ITEM 1.  BUSINESS

         The Company supplies network information  security products that enable
the secure  transmission  and  authentication  of data over local area  networks
("LANs"),  wide area networks ("WANs") and public packet switched networks, such
as the  Internet.  The Company's  broad line of  information  security  products
provides  an  integrated   solution  that   prevents   unauthorized   access  or
manipulation  of  information,  enables  secure  electronic  commerce  over  the
Internet and allows mobile users to securely access corporate  networks.  Cylink
further   offers  a  line  of  spread   spectrum  radio  products  for  wireless
transmission  of voice and data  communications  which operate in the unlicensed
spread  spectrum  bands adopted by the U.S.  Federal  Communications  Commission
("FCC") in 1985 and subsequently  adopted in many other countries throughout the
world. The Company's spread spectrum radio products focus primarily on the fixed
location, outdoor, wireless communications infrastructure market.

         The  Company  was  formed  in 1984 as a  partnership  and  subsequently
incorporated  in California in 1989. In February and March of 1996,  the Company
completed its initial public  offering and its Common Stock began trading on the
Nasdaq National Market under the symbol CYLK. Through the offering,  the Company
sold 5,750,000  shares of its Common Stock which generated  approximately  $79.3
million of cash, net of underwriting  discounts,  commissions and other offering
costs.  The Company  operates in one industry  segment -- secure  communications
products.  The  Company's  operations  outside  of  the  United  States  consist
primarily  of a sales and service  office in the United  Kingdom,  with  smaller
sales  offices  in  several  other  countries.  See  Note  11 of  the  Notes  to
Consolidated Financial Statements for geographic area information.

Industry Background

         The demand  for  information  security  and  authentication  of data in
computer  networks  has  increased  significantly  as a result of the shift from
mainframe to  distributed  computing  and the  increasing  use of shared  public
packet switched  




                                       2
<PAGE>

networks, such as the Internet. The increased number of users that can now share
computing  resources and communicate  with each other over LANs, WANs and public
networks  raises  significant  new  access  and  security  issues  that are more
difficult to address than in mainframe-based host systems.

         Over the last decade, the shift from mainframe to distributed computing
has   increased   the  level  of  electronic   information   transmission.   The
client/server    environment   enables   information   sharing   and   efficient
communications that are increasingly seen as competitive advantages in business.
In addition,  the prevalence and  ease-of-use  of modem-based  connections  have
broadened the definition of a LAN,  enabling users in remote locations to access
the central  databases and  applications on the LAN.  However,  as organizations
increasingly rely on electronic  transmission of data, their information becomes
increasingly vulnerable. Individuals have been able to exploit system weaknesses
to gain unauthorized  access to networks,  network  transmissions and individual
network computers,  and have used such access to alter or steal data or, in some
cases,  to launch  destructive  attacks on data or  computers  within a network.
Several  well-publicized  attacks have brought  attention to certain  attackers'
techniques (given colorful names such as "packet spoofing," "password sniffing,"
"Trojan horse," and "session hijacking").

         Until 1993, the primary means by which  sensitive data was  transmitted
between distant points within a WAN was through  private leased lines.  Cost and
other  factors have led  organizations  to move away from these  private  leased
lines to public  networks,  such as the  Internet.  Compared  to private  leased
lines,  public  networks offer improved  support at a  significantly  lower user
charge due to economies  of scale  achieved  through the larger  number of users
sharing the network.  While providing these benefits, the use of public networks
increases the need to ensure the security of information  transmitted over these
networks. In public networks,  transmitted information is exposed to others, who
can, in the absence of effective security  measures,  gain access to, manipulate
and divert the transmitted data.

         Public networks enable  connections among home personal computer ("PC")
users,  remote users and  corporate  networks.  Much of the recent growth of the
Internet has been attributed to an increase in commercial  access  providers and
organizations  seeking to market products or services to users. The Internet and
other  public  networks  are enabling  increasing  numbers of computer  users to
engage in electronic commerce,  such as banking,  trading securities,  verifying
credit  and  purchasing  products  and  services.  These  increasing  levels  of
electronic  commerce  place a premium on ensuring the  integrity and security of
information transmission.

         Complete  information  security  solutions  for LANs,  WANs and  public
networks must perform each of the following five critical functions:

o    Access  control -- Access to a  computer  network  must be limited  only to
     specific authorized users.

o    Privacy  -- An  authorized  user must be  prevented  from  viewing  another
     party's private data.

o    Authentication -- The receiver of the transmitted  information must be able
     to verify the identity of the sender.

o    Integrity  -- The  receiver  and the sender must know that the  transmitted
     data has not been changed or compromised by any unauthorized manipulation.

o    Non-repudiation -- Both the sender and receiver must be able to verify that
     a data  transmission  has been  executed and cannot be later  repudiated by
     either party.

         To date, a substantial  portion of the demand for information  security
over public  networks has been addressed by only partial  solutions.  "Firewall"
products offer access control primarily by filtering incoming  information based
on packet addresses. Greater access control is possible with secret passwords of
various types, including the use of time-varying and challenge-response password
tokens.  These tokens and access control systems generally provide some level of
user authentication,  but no privacy,  integrity or non-repudiation.  Many other
encryption  products  provide  privacy,  but do not perform  the other  security
functions,  nor are they easily controlled or managed from one central location.
The Company believes that the use of public networks for electronic commerce and
other  applications has been slowed to date by concern over network security and
that solving security issues will increase the types of applications that can be
accessed through public networks.

The Cylink Solution

         Through its recently  introduced  products and those under development,
Cylink offers information  security products designed to provide a comprehensive
system-wide  information  security  solution  that  addresses  the five critical
functions   of  access   control,   privacy,   authentication,   integrity   and
non-repudiation in a scaleable, centrally-managed 


                                       3
<PAGE>

system. The Company's  products  incorporate the latest  commercially  available
security   technologies,   including  Public  Key   cryptography-based   digital
signatures,  certificates and key exchange techniques,  which enable the Company
to offer a broad,  flexible and scaleable  information  security  solution.  The
Company's  information  security products incorporate Cylink's Secure Enterprise
Architecture  Stack,  an  integrated  group of software  security  modules  that
provide the foundation for an enterprise-wide information security solution.

The Cylink Strategy

         The Company  intends to maintain its position as a leading  provider of
enterprise-wide  information  security solutions and to establish  standards for
the  secure  exchange  of  information  among  users  of LANs,  WANs and  public
networks, such as the Internet. The Company seeks to achieve these goals through
the following strategies:

o    Offer Comprehensive  Enterprise-Wide  Information  Security Solutions.  The
     Company's strategy is to offer a broad,  centrally  manageable and flexible
     line of  information  security  products  that  provides a virtual  private
     network  from end  node to end  node.  The  Company's  recently  introduced
     products and those under  development are designed to authenticate the user
     (not just the IP  address)  and  prevent  unauthorized  access to a network
     system and information within that system.

o    Maintain and Leverage Technology Expertise in Public Key Cryptography.  The
     Company plans to maintain its  technology  expertise in the  application of
     Public Key  cryptography  through a  combination  of internal  research and
     development  efforts,  government  research and  development  contracts and
     customer funded research,  and partnering with strategic vendors,  focusing
     on  technologies  that are  critical  to the  proliferation  of  electronic
     commerce  over  public  switched  networks.  The  Company's   technological
     achievement  has  resulted  in the use of  Cylink's  products  by the  U.S.
     Federal  Reserve  System and  Society  for  Worldwide  Interbank  Financial
     Telecommunications  ("S.W.I.F.T."), and the development of one of the first
     government  approved key recovery  architectures.  In 1996, the Company had
     net research and development expenses of approximately $11.3 million.

o    Broaden Use of Public Key Technology through  Licensing.  The Company seeks
     to proliferate its specific  methods of implementing  Public Key technology
     by licensing  certain of its core  technical  components and its Public Key
     cryptographic  libraries to  strategic  partners.  To encourage  the use of
     Public Key  cryptography,  the Company has licensed  the  Stanford  Patents
     (defined  below)  to over  30  companies,  including  Cisco  Systems,  Inc.
     ("Cisco"),  3Com Corporation,  Hughes Aircraft Company,  Intel Corporation,
     Microsoft  Corporation,  Motorola,  Inc.,  Open  Market,  Inc.,  PictureTel
     Corporation,  Scientific-Atlanta,  Inc., Sun Microsystems,  Inc. and Tandem
     Computers,  Inc. The Company's technology licensing partnership with Cygnus
     Solutions,  Inc.  enables software  developers to incorporate  basic Cylink
     information security protocols and techniques into their software products.
     The Company's goal is to provide a migration  path that enables  vendors to
     upgrade their systems with certain base technology  which is  complementary
     with the Company's products.

o    Expand  into  Emerging  Public  Network  Markets.  The  Company  intends to
     leverage its expertise in providing  solutions for virtual private networks
     by introducing new information  security products for public network users.
     Demand for information  security has historically  been limited to business
     in  security-conscious  industries  such  as  banking,  telecommunications,
     aerospace and defense.  However, with the increased use of the Internet and
     public  networks,  as well as  remote  access  to LANs  and  WANs,  network
     security  is  of   increasing   concern  to  most   businesses   and  other
     organizations that use network-based information resources.

o    Build and Foster Strategic  Relationships.  The Company intends to continue
     to develop strategic marketing and product  development  relationships with
     key original  equipment  manufacturers  ("OEMs") in order to further market
     acceptance of the Company's products. For example, the Company has licensed
     to Cisco certain of its software  security  module  protocols under its OEM
     agreement to provide enhanced  information  security  solutions for Cisco's
     customers.

         Note, however,  that the market for the Company's  information security
products is only beginning to emerge.  This market is  characterized  by rapidly
changing technology,  emerging industry standards, new product introductions and
changes in customer  requirements  and  preferences.  The Company's  future will
depend in part upon end  users'  demand for  information  security  products  in
general,  and upon the Company's ability to enhance its existing products and to
develop  and  introduce  new  products  and  technologies   that  meet  customer
requirements.  Any significant advance in techniques for attacking cryptographic
systems  could  render some or all of the  Company's  existing  and new products
obsolete or unmarketable.  To the extent that the Company is unable to adopt and
incorporate emerging standards for implementing information security in a market
segment,  sales of the  Company's  existing and planned  products in that market
segment would be significantly less than the levels currently anticipated by the
Company. There can be no assurance that 



                                       4
<PAGE>

information  security-related  products or technologies developed by others will
not adversely affect the Company's  competitive  position or render its products
or technologies  noncompetitive  or obsolete.  See "Business - Risk Factors That
May Affect  Future  Results --  Competition,  -- Evolving  Information  Security
Market, and -- Rapid Technological Change."

Technology

         The  Company's  information  security  products are based on Public Key
cryptography  techniques,  which  were  first  developed  in  1976  at  Stanford
University by Drs.  Diffie and Hellman.  The Company has the exclusive  right to
sublicense  certain  patents that were  granted to Stanford  with respect to the
original  Public Key methods (the  "Stanford  Patents").  The  Stanford  Patents
issued in the  United  States  will  expire in the third  quarter  of 1997.  See
"Business - Risk Factors That May Affect Future Results -- Intellectual Property
and Other  Proprietary  Rights." The Public Key cryptography  methods adopted by
the Company require that each user be assigned both a private  number,  which is
confidential,  and a mathematically related public number, which can be revealed
without  compromising  the user's private  number.  Diffie-Hellman  key exchange
provides  for two users in a data network to exchange  their public  numbers and
then compute a shared secret  number that is unique to them.  This shared secret
number  can  then  be  used  as the  secret  encryption  key  in a  conventional
encryption  system to  maintain  the  privacy of the  communication  between two
users.

         The Company has adopted advanced Public Key digital signature  methods.
An individual's  digital  signature is a set of unique binary numbers,  which is
derived from a combination of the message and the signer's  private number.  Any
user in the network can verify this digital signature by using only the sender's
public number.  Digital  signature methods are part of the foundation for secure
electronic  transactions  that  can  scale  to  potentially  millions  of  users
conducting commerce on the Internet.

         The  Company's  products  enable  network   administrators  to  act  as
certificate  authorities that permit each authorized user in the network to have
his or  her  public  number  validated  for  the  purpose  of  establishing  its
authenticity  to  other  users.  The  certification   authority   provides  each
authorized user with an electronic  message  containing that user's name, public
number,  unique  privileges within the network and expiration date. This message
is  digitally  signed  by  the  network   administrator  to  create  the  user's
certificate,  which in effect  serves to notarize the user's  public  number and
enable that user to conduct secure  communications  with other  certified  users
within the network.  Certificates can also be issued by a public authority, such
as that contemplated by the U.S. Postal Service's pilot program, to authenticate
users of public networks such as the Internet.

         The Company has developed an  integrated  set of  independent  software
modules on which the Company's  information  security  products are based.  This
software  incorporates Public Key cryptography  techniques in its key management
system,  digital  signatures and  certificates  to provide  complete,  scaleable
enterprise-wide  security  solutions.  This  flexible  architecture  includes  a
certification authority and a network management system that enables the network
administrator to create virtual private workgroups.

         The Company designs application  specific integrated circuits ("ASICs")
and custom integrated circuits to implement its encryption algorithms and Public
Key  techniques  in  order  to  provide  increased  performance,   security  and
functionality in its products at reduced cost.  Cylink's  significant  technical
achievements  in the area of proprietary  ASIC design include  encryption  chips
with speeds up to 155 megabits per second  ("Mbps") and Public Key  co-processor
chips that have the capability of handling 1,024 bit numbers.

         Cylink has developed  hardware and software  implementations of network
interfaces,  standards and protocols.  Cylink information  security products are
designed to secure existing  networks without reducing  performance or requiring
modifications  of  existing  network  hardware  or  software.  The  Company  has
developed a broad range of network  interfaces  for its products,  which enables
the  Company's  security  products  to  connect  to most  networks  in use today
throughout  the world.  The current list of network  interfaces  used in Company
products  include:  T1 (1.5 Mbps),  T2 (6.2 Mbps), T3 (45 Mbps), E1 (2 Mbps), E3
(34 Mbps),  X.25,  V.35,  X.21,  Frame Relay  (FRF.1,  FRF.3 and FRF.4),  NTT T1
(Japan), 10 Base 2, 10 Base 5, 10 Base T, HSSI, RS-232 and RS-422.

Information Security Products

         Cylink originally entered the information  security market in 1986 with
hardware-based  link  encryptors to secure  transmissions  between users in WANs
that were communicating over private, leased communication lines. These original
products formed the foundation for Cylink's  SecureWAN  product line, which is a
family of encryption  products that 


                                       5
<PAGE>

provide security solutions for WANs operated by government  agencies,  financial
institutions,  Fortune  1000  companies  and  telecommunications  companies.  In
response to the movement of WAN users to public  networks,  Cylink has developed
packet encryptors that enable secure transmission of packets of data between two
points  in  X.25  and  Frame  Relay  based  public  networks.   Because  of  the
proliferation  of LANs,  the Company  developed  its  SecureLAN  product line to
manage,  control and monitor information within a LAN. Cylink also developed its
SecureAccess  product line to allow  remote and mobile  users  secure  access to
their corporate computing resources.

         The  Company's   products  are  designed  to  be  modular,   scaleable,
configurable  and easy to use.  Customers can easily configure and upgrade their
Cylink security  systems through the purchase of Cylink products that meet their
specific,  evolving  information  security needs. Most of the Company's recently
introduced products are based upon the Company's Secure Enterprise  Architecture
Stack and are designed to be managed as an  integrated,  interoperable  security
system by the Company's SecureManager products.

         SecureWAN Product Family.  The Company's  SecureWAN product family is a
complete line of link  encryptors  that utilize  Diffie-Hellman  key  management
techniques  to  support  conventional  encryption  algorithms,  such as the data
encryption standard ("DES") and Cylink proprietary algorithms.  Depending on the
product  model,  the  SecureWAN  encryptors  operate at varying  data rates over
private and public networks and support most widely used data link protocols.

         The Company's original CIDEC line of data and voice encryption products
offers full encryption and access control and is available in a number of models
that range from high speed T1 and T3 data transfer rates (1.54 Mbps and 45 Mbps,
respectively)  to low speed transfer rates (1200 bits per second to 256 kilobits
per second ("kbps")).  The Company believes that its CIDEC-VHS/VHX  products are
the fastest data link encryptors commercially available in the world today.

         Cylink's  high  speed   SecureX25H  and  low  speed   SecureX25L  offer
encryption for public switched packet networks based on X.25 packet transmission
technology and support data rates up to 64 kbps and up to 512 virtual circuits.

         Cylink's  SecureFrame  product is  designed  to operate as a  dedicated
Frame  Relay  encryptor  capable of  operations  on any public or private  Frame
Relay-based  network. The SecureFrame is designed to support data rates of up to
2.048 Mbps and up to 1,024 user addresses.

         SecureLAN  Product Family.  The Company's  SecureLAN  product family is
designed to provide packet-based  security solutions for both private and public
networks.  The Company's  SecureLAN products are designed to allow a customer to
create and control access to groups within the network, known as virtual private
workgroups.  For example,  a customer could  segregate  within a network certain
departments,  such as human resources and finance,  denying employees from other
departments  access to files  within the  virtual  private  workgroup.  Further,
within a  virtual  private  workgroup,  the  Company's  SecureLAN  products  are
designed  to allow  certain  users,  such as the  director  of human  resources,
greater access to files than other users.

         The SecureDomain  product is a hardware device that resides between the
router and  subnet in a LAN.  The  SecureDomain  product  supports  simultaneous
secured  TCP/IP  and  IPX  communications   among  networks  and  subnets.   The
SecureDomain  product is designed to allow  organizations to use the Internet as
part of their own secure virtual private network.  Under the Company's  existing
licensing relationship with Cisco, Cisco is authorized to embed the SecureDomain
software product in its router products as part of Cisco's IOS operating system.

         Cylink's  SecureNode  products  are  under  development  and are  being
designed to extend the  functionality  of  SecureDomain to the desktop level and
enable  encryption at substantially  faster speeds than are currently  available
from software-only solutions.

         SecureAccess  Product  Family.  Addressing  the need for secure  remote
access to private networks,  the Company's SecureAccess product line is designed
to enable secure dial-up access to a corporation's  LAN or WAN. The SecureAccess
products can be combined to create an access control  solution that provides the
network administrator with the five critical functions of network security for a
virtual private network over public switched  telephone  networks  ("PSTNs") and
the  Internet.  The  SecureAccess  product  line  is  scaleable  to  accommodate
thousands of users and, among other applications, can enable electronic commerce
over the Internet.

         The SecureGate Server,  which physically resides between the customer's
communications  server and modems, can monitor and protect corporate information
resources by  controlling  incoming and outgoing  calls to and from the network.
SecureGate  provides  centralized  management  and  tracking of remote users and
their individual security profiles,  with audit trails of all system activities.
SecureGate also acts as the certificate authority for the SecureAccess system.

         SecureTraveler  for Windows is a PC-based  software security client for
SecureGate and responds to customers'  needs to share critical  information over
PSTNs and the Internet. SecureTraveler is designed to operate transparently with
Windows  communications  applications  to secure  end-to-end  sessions  in their
entirety.

         SecurePocket Traveler is a pocket-sized,  hardware security device that
is inserted between a laptop PC, desktop PC or other computer device and a modem
and provides security  functions similar to those provided by SecureTraveler for
Windows.

         SecureManager.  The  SecureManager  is  designed  to allow the  network
administrator  to centrally  manage the security  features of a secured network,
subnet,  host and node within a LAN, to create or dissolve secure workgroups and
to  monitor  the  performance  of other  Cylink  products  within  the  network.
SecureManager  enables the network administrator to configure,  manage,  install
and modify all  information  security  within a LAN or WAN from one point in the
network.

         The Company's  future results of operations will be highly dependent on
the   successful   marketing  and  customer   acceptance  of  the   SecureFrame,
SecureManager,    SecureGate,   SecureTraveler,    SecurePocket   Traveler   and
SecureDomain products, which were recently introduced.  To date, the Company has
made only  modest  commercial  shipments  of  certain  of such  products  and no
commercial  shipments of the  remainder of such  products.  No assurance  can be
given  that  these  products  will  not  require  additional  development  work,
enhancement,  testing or further  refinement  before they can be 



                                       7
<PAGE>

introduced  and made  commercially  available  by the  Company or that they will
achieve market  acceptance.  If such new and recently  introduced  products have
performance,  reliability,  quality or other  shortcomings,  then such  products
could fail to achieve market  acceptance and the Company may experience  reduced
orders, higher manufacturing costs, delays in collecting accounts receivable and
additional  warranty  and  service  expenses,  which in each case  could  have a
material  adverse  effect on the  Company's  financial  condition and results of
operations.  See  "Business - Risk  Factors  That May Affect  Future  Results --
Dependence on Recently Introduced and New Information Security Products,  and --
Product Liability Risks."

Sales, Marketing and Customer Support

         Cylink markets its information  security products primarily through its
direct sales force and, to a lesser extent,  through  distributors and OEMs. The
Company's  direct  sales  force  operates  from the  Company's  headquarters  in
Sunnyvale,  California  and from four sales  offices,  and  directs  its efforts
primarily at government agencies, financial institutions, Fortune 1000 companies
and telecommunication  carriers.  Cylink's sales force,  engineers and technical
personnel  work closely with  customers in order to design  system  security and
network configurations that are tailored to the customers' needs.

         International sales of information security products are made primarily
through the Company's six foreign sales offices and numerous  distributors.  The
Company  does  not  have  long-term  contractual  relationships  with any of its
distributors  and,  therefore,  has no assurance  of a  continuing  relationship
within a given market.

         To date, the customers of the Company's  information  security products
have  primarily  consisted of Fortune 1000  companies,  financial  institutions,
government  agencies  and  telecommunication  carriers  who  use  the  Company's
SecureWAN  products to encrypt and secure their private  leased line WANs.  From
inception  through  December  31,  1996,  the Company  sold over $125 million of
information  security  products in the U.S. and abroad.  Demand for computer and
network   security   has   historically    been   limited   to   businesses   in
security-conscious industries such as banking, telecommunications, aerospace and
defense.  However,  with the increased use of WANs,  public  networks and remote
access to LANs and WANs,  network  security  is of  increasing  concern  to most
businesses  and  other   organizations   that  use  computer-  or  network-based
information resources.

Wireless Communications Product Line

         Cylink offers a line of spread  spectrum  radio  products that are used
for wireless  transmission of voice and data communications which operate in the
unlicensed  spread  spectrum  bands adopted by the FCC in 1985 and  subsequently
adopted in many other countries throughout the world. In 1990, the Company began
to focus on the growing market for 



                                       8
<PAGE>

wireless  communications,  particularly that section of the wireless market that
cannot be addressed by conventional  wireless cellular  solutions.  During 1994,
1995 and 1996, sales of AirLink products  accounted for  approximately  32%, 38%
and 50%,  respectively,  of the Company's revenue. A large portion of the demand
for wireless  communications  products comes from developing countries where the
absence  of  a  reliable  wired  telecommunications  infrastructure  provides  a
significant opportunity for a wireless spread spectrum based solution to respond
to the growing need for modern data communications capabilities.

         The Company's AirLink product line was first introduced in 1991 and has
two  primary  applications.  The  first  application  is  to  provide  telephone
connectivity  to remote  locations  where the  limited  number of users does not
justify the cost of a cellular station or wired  communications link. AirLink is
capable of providing  point-to-point  communications over distances up to thirty
miles.  The  second  application  is to provide a data  transmission  network in
locations,   such  as  developing  countries,   where  wired  telecommunications
infrastructure is either  unreliable or nonexistent.  Cellular phone systems are
designed for voice communications,  and are believed by Cylink's customers to be
too expensive for, and do not support sufficiently fast data transfer rates for,
data communications.

         In addressing these two markets, the Company has positioned its AirLink
product  line  between  the  full  featured,  point-to-point,  very  high  speed
microwave radio links and the high volume,  low power spread  spectrum  wireless
devices. The Company believes that its AirLink product line responds to a market
need that exists between these two ends of the marketplace for a cost effective,
ruggedized, outdoor wireless product offering that is capable of transmitting at
medium  data rates  between  19.2 kbps and 2 Mbps.  The  Company  offers over 20
different models of its AirLink products to specifically address a wide range of
individual customer needs within this market segment.

         The Company's  strategy for its AirLink product line is to provide last
mile and data  network  solutions at ranges of up to 30 miles and to continue to
seek  feature  improvements  and cost  reductions  to enhance and  maintain  its
position within this market segment.  The Company intends to maintain its strong
technical  position in the  wireless  communications  market  through  continued
improvement  of its radio  frequency  designs,  ASIC  modem  chips and  software
modules.

                                       9
<PAGE>

         The Company believes that it has certain core technical competencies in
spread spectrum signal  processing that have enabled its AirLink product line to
be high performance, cost-effective solutions for its targeted applications. The
Company has developed  certain  radio  frequency  ("RF") and  microwave  circuit
designs that provide  high  sensitivity  to weak  signals  while  retaining  the
ability to reject  out-of-band  interference.  The AirLink product line has been
approved for use by over 30 foreign  governments.  All Cylink wireless  products
are based on  proprietary,  custom  integrated  circuits  that  permit low power
operation,  are cost-effective and easy to manufacture.  The Company has further
developed a number of wireless  architecture  features and  algorithms and holds
five U.S.  patents for such  features  as spread  spectrum  correlation  design,
multi-user  detection  schemes and spread spectrum  modulation and  demodulation
designs. The Company believes that this combination of proprietary  technologies
and experience in spread  spectrum  radio have given it a competitive  advantage
with  respect  to the  breadth  of data rates  covered,  network  manageability,
transmission range and ease of use.

         The Company directs its wireless sales and marketing  efforts primarily
at   countries   that  do  not   have  a   reliable   wired   telecommunications
infrastructure.  These sales are made  primarily  through value added  resellers
("VARs") and distributors and, to a lesser extent, directly by Cylink in certain
targeted  applications.  Cylink intends to pursue strategic  alliances with both
international  and domestic  system  integrators  and other  partners that would
integrate  AirLink  products  into their last mile  solutions for voice and data
networks. Cylink believes that this strategy will be particularly significant in
developing  countries  where  alliances  with local  partners can provide better
access to and knowledge of these local markets.  International customers for the
AirLink  products  include  Dole  Fruit & Nut Co.  (Central  America),  Pakistan
Telecommunications  Corp., Unicom (China), IUSAC (Mexico), Banco Popular (Puerto
Rico),  the post office for the Czech Republic and Chase Manhattan Bank.  United
States end users of AirLink products include AT&T Corp.  ("AT&T"),  Southwestern
Bell, Cellular One, the U.S. State Department,  Lockeed Martin Corporation,  the
U.S. Department of Energy, AirTouch Cellular, GTE MobilNet, Peek Traffic/Transyt
and McCain Traffic Supply.

Research and Development

         The  Company's   research  and  development   efforts  are  focused  on
developing  new  products,   core  technologies  and  enhancements  to  existing
products.  For its information  security  products,  the Company's  research and
development strategy has in recent periods focused on the development of modular
software and hardware products that can be readily integrated and adapted to the
changing standards and requirements of the  communications  and  internetworking
industries.  A focus of the Company's  research and development  efforts in 1996
has  been the  development  of the  SecureLAN,  SecureAccess  and  SecureManager
product  families.   The  Company  expects  that  it  will  continue  to  devote
substantial research and development  resources to the enhancement of its Secure
Enterprise Architecture Stack software modules for the foreseeable future.

         The Company's research and development  efforts for its AirLink product
line are focused on strengthening  its position in the fixed location,  outdoor,
wireless  communications  infrastructure  market.  The Company's  principal 1996
development effort for its AirLink products was the development and introduction
of a new AirLink  T1/E1  wireless  system,  which the Company  expects will be a
primary focus of its continuing product  enhancement and cost reduction efforts.
The Company also  expects to continue  development  of its custom ASIC  wireless
components, which provide the core for the AirLink product line.

         In 1994,  1995 and 1996, the Company's  gross research and  development
expenses were $8.8 million, $11.3 million and $17.4 million, respectively.  From
time to time, the Company receives  engineering funding for development projects
to apply or enhance the Company's  technology to a particular  customer's  need.
The amount recognized under these research and development  contracts are offset
against research and development expense. Amounts recognized under non-recurring
engineering  contracts  totaled $0.7  million,  $1.1 million and $6.1 million in
1994, 1995 and 1996, respectively.

         The Company  believes that its ability to attract and retain  qualified
development  personnel is essential to the success of its development  programs.
The  market  for  such  personnel  is  highly   competitive  and  the  Company's
development   activities   could  be  adversely   affected  if  the  Company  is
unsuccessful  in  attracting  and retaining  skilled  technical  personnel.  See
"Business - Risk Factors That May Affect  Future  Results --  Dependence  on Key
Personnel,  and  --Management  of  Growth."  In  addition,  the  markets for the
Company's products are characterized by rapidly changing technologies, extensive
research and new product  introductions.  The Company  believes  that its future
success will depend in part upon its ability to continue to enhance its existing
products and to develop and  introduce new  products.  As a result,  the Company
expects to continue to make a significant  investment in  engineering,  research
and  development.  There can be no  assurance  that the Company  will be able to
develop and introduce new products or enhancements to its existing 



                                       10
<PAGE>

products  in a timely  manner  which  satisfy  customer  needs,  achieve  market
acceptance or address  technological  changes in its target markets. The failure
of the Company to develop  products and introduce  them in a timely manner could
adversely affect the Company's  competitive  position,  financial  condition and
results of  operations.  See  "Business - Risk  Factors  That May Affect  Future
Results -- Competition, -- Dependence on Recently Introduced and New Information
Security   Products,   --  Evolving   Information   Security  Market,  --  Rapid
Technological  Change,  and  --  Wireless   Communications  Industry  Regulatory
Environment."

Regulatory Matters

         The Company's  information  security products are subject to the export
restrictions  recently  transferred to administration by the U.S.  Department of
Commerce,  which  license the export of encryption  products  subject to certain
technical restrictions.  In addition, these U.S. export laws prohibit the export
of encryption  products to a number of hostile  countries.  Although to date the
Company has been able to secure all U.S. export licenses routinely, there can be
no assurance  that the Company will  continue to be able to secure such licenses
in a timely manner in the future, or at all. In certain foreign  countries,  the
Company's  distributors  are  required to secure  licenses or formal  permission
before encryption products can be imported.  To date, except for certain limited
cases, the Company's  distributors have not been denied permission to import the
Company's products.  See "Business - Risk Factors That May Affect Future Results
- -- Risks  Associated  with  International  Sales;  Reliance Upon Local Partners;
Restrictions on Export."

         The Company's  wireless  products are subject to regulations of the FCC
and regulations of the  telecommunications  regulatory authority in each country
where the  Company  sells its  products.  These  regulations  are in the form of
general  approval to sell  products  within a given  country for  operation in a
given frequency  band, one time equipment  certification,  and, at times,  local
approval for  installation.  In the United States,  all Cylink wireless products
are subject to FCC Part 15 rules on unlicensed spread spectrum operation. In the
international markets, government regulations vary. In those countries that have
accepted certain worldwide standards,  such as the FCC rulings or those from the
European  Telecommunications  Standards  Institute,  Cylink has not  experienced
significant  regulatory  issues in bringing its products to market.  Approval in
these  markets  involves  retaining  local testing  agencies to verify  specific
product  compliance.  However,  many developing  countries,  including the large
markets  in India and  China,  have not  fully  developed  or have no  frequency
allocation,  equipment certification or telecommunications regulatory standards.
In these markets,  Cylink is actively  working,  both directly and with industry
standard bodies, to conform regulations to worldwide standards.  See "Business -
Risk Factors That May Affect Future Results -- Wireless  Communications Industry
Regulatory Environment."

Backlog

         Orders for the Company's products are usually placed by customers on an
as-needed  basis and the Company has typically been able to ship products within
thirty days after the customer  submits a firm  purchase  order.  The  Company's
backlog consists of all orders received,  regardless of the anticipated shipping
date.  Because of the possibility of customer  changes in delivery  schedules or
cancellation of orders,  the Company's backlog as of any particular date may not
be  indicative  of sales in any future  period.  The Company does not  generally
maintain  long-term  contracts  with its  customers  that  require  customers to
purchase the Company's  products.  The Company's backlog as of December 31, 1995
and 1996 was  approximately  $5.1 million and $6.9  million,  respectively.  See
"Business - Risk Factors That May Affect Future Results -- Lengthy Sales Cycle."

Manufacturing

         The Company's  manufacturing  operations consist primarily of component
procurement,  final assembly and test, and quality control of subassemblies  and
systems.  The  Company  generally  uses  domestic  independent   contractors  to
manufacture  and assemble  printed  circuit boards.  The  manufacturing  process
enables the Company to configure  the hardware and software in  combinations  to
meet a wide variety of customer requirements.  The Company installs its software
into the  electronically  programmable  read  only  memory  of its  products  to
maintain  quality control and security,  and performs  "burn-in"  procedures and
functional tests, as well as comprehensive inspections to assure the quality and
reliability of its products.

         The Company's product designs are proprietary but generally incorporate
industry-standard  hardware components.  However, certain semiconductor devices,
electronic components and subassemblies are presently purchased from sole source
suppliers.  Certain other  components  are presently  available or acquired from
only a limited number of suppliers.


                                       11
<PAGE>

         The Company's  ability to timely deliver its products is dependent upon
the  availability  of quality  components and subsystems used in these products.
The Company depends in part upon  subcontractors  to  manufacture,  assemble and
deliver  certain  items in a  timely  and  satisfactory  manner.  A  significant
interruption in the delivery of such items could have a material  adverse effect
on the Company's  results of  operations.  See "Business - Risk Factors That May
Affect Future  Results -- Dependence  on Component  Availability,  Subcontractor
Performance and Key Suppliers."

Employees

         As of December 31,  1996,  the Company had 347  employees,  of whom 119
were primarily engaged in research and development,  98 in sales,  marketing and
related   customer  support   services,   26  in   administration   and  104  in
manufacturing.  Of these employees, 326 were located in the United States, 15 in
Europe  and 6 in Asia.  None of the  Company's  employees  is  represented  by a
collective  bargaining  agreement  with respect to his or her  employment by the
Company,  nor has the Company  experienced  any  organized  work  stoppage.  The
Company considers its relations with its existing employees to be good.

RISK FACTORS THAT MAY AFFECT FUTURE RESULTS

Recent Losses;  Potential  Fluctuations in Operating  Results,  Future Operating
Results Uncertain.

          Due  primarily  to  increased  research  and  development,  sales  and
marketing, and litigation expenses, the Company incurred losses in 1994 and 1995
and the first six months of 1996.  There can be no  assurances  that the Company
will  increase or maintain  its revenue or be  profitable  on a quarterly  or an
annual basis in the future.

         The Company has historically  experienced  significant  fluctuations in
its operating  results on an annual and a quarterly  basis and could  experience
such fluctuations in the future. The Company's operating results are affected by
a number  of  factors,  many of which  are  outside  of the  Company's  control,
including:  the timing of the  introduction  of new or enhanced  products by the
Company or its  competitors;  market  acceptance of new products of the Company,
its customers and its competitors; the timing, cancellation or delay of customer
orders,   including  cancellation  or  delay  in  anticipation  of  new  product
introduction   or  enhancement  or  resulting  from   uncertainty   relating  to
intellectual property claims;  competitive factors, including pricing pressures;
changes  in  operating  expenses,  including  those  resulting  from  changes in
available  production capacity of independent  foundries and other suppliers and
the availability of raw materials; expenses associated with obtaining, enforcing
and defending claims with respect to intellectual  property  rights;  the mix of
products sold;  changes in the percentage of products sold through the Company's
direct  sales  force;  personnel  changes;  general  economic  conditions;   and
fluctuations  in  foreign  currency  exchange  rates.  The  Company  expects  to
introduce a number of new products in 1997.  The failure of such new products to
achieve market  acceptance at the time  anticipated  by the Company,  or at all,
would  materially  and adversely  affect the Company's  financial  condition and
results of operations.

Pending Litigation

See Item 3. "Legal Proceedings."

Dependence on Key Personnel

         On November 13, 1996, the Company  announced the appointment of Fernand
B. Sarrat as President and Chief  Executive  Officer  ("CEO").  Mr. Sarrat,  45,
succeeds Lewis C. Morris,  64, who resigned in July, 1996. Dr. Jim Omura,  Chief
Technology Officer, had been serving as acting CEO. At this time, the Company is
unable to assess the  potential  impact  resulting  from the  retirement  of Mr.
Morris,  a co-founder  of the Company,  and the  transition to Mr. Sarrat as new
CEO.

         The  Company's  future  success  will  depend to a large  extent on the
abilities of and successful  transition to Mr. Sarrat as the new CEO, as well as
the  contributions  by its  executive  officers,  key  management  and technical
personnel.  The failure to  successfully  integrate Mr. Sarrat into the Company,
loss of the services of one or more of the Company's  executive  officers or key
personnel,  or the inability to continue to attract qualified  personnel,  could
delay product  development cycles or otherwise have a material adverse effect on
the Company's business and operating results.


                                       12
<PAGE>

Lengthy Sales Cycle

         Sales  of  the  Company's  products  generally  involve  a  significant
commitment  of  capital  by  customers,  with the  attendant  delays  frequently
associated  with large capital  expenditures.  For these and other reasons,  the
sales cycle  associated  with the  Company's  products is typically  lengthy and
subject to a number of significant risks over which the Company has little or no
control.  The  Company  is often  required  to ship  products  shortly  after it
receives orders and, consequently,  order backlog at the beginning of any period
has in the past  represented  only a small  portion  of that  period's  expected
revenue. As a result,  product revenue in any period is substantially  dependent
on orders  booked and shipped in that period.  The Company  typically  plans its
production and inventory levels based on internal  forecasts of customer demand,
which is highly unpredictable and can fluctuate substantially.  If revenue falls
significantly  below anticipated  levels, the Company's  financial condition and
results of operations would be materially and adversely  affected.  In addition,
the Company's  operating expenses are based on anticipated  revenue levels and a
high percentage of the Company's expenses are generally fixed in the short term.
Based on these  factors,  a small  fluctuation  in the timing of sales can cause
operating results to vary significantly  from period to period. In addition,  it
is possible that in the future the Company's operating results will be below the
expectations of securities  analysts and investors.  In such an event, or in the
event that adverse  conditions  prevail or are perceived to prevail generally or
with respect to the Company's business,  the price of the Company's Common Stock
would likely be materially adversely affected.

Dependence on Recently Introduced and New Information Security Products

         The Company's  future results of operations will be highly dependent on
the successful completion of the design,  development,  introduction,  marketing
and manufacture of the SecureManager and SecureNode products,  some of which are
under development,  and the SecureGate,  SecureTraveler,  SecurePocket Traveler,
SecureFrame and SecureDomain products, which were recently introduced.  To date,
the  Company  has made only  limited  commercial  shipments  of  certain of such
products and no  commercial  shipments of the  remainder  of such  products.  No
assurance  can be given that any of such  products  will not require  additional
development work, enhancement,  testing or further refinement before they can be
introduced  and made  commercially  available  by the  Company or that they will
achieve market  acceptance.  If such new and recently  introduced  products have
performance,  reliability,  quality or other  shortcomings,  then such  products
could fail to achieve market  acceptance and the Company may experience  reduced
orders, higher manufacturing costs, delays in collecting accounts receivable and
additional  warranty  and  service  expenses,  which in each case  could  have a
material  adverse  effect on the  Company's  financial  condition and results of
operations.

Competition

         Competition is intense among providers of information  security systems
and wireless communications  equipment and systems, and the Company expects such
competition to increase in the future.  Significant competitive factors in these
markets  include the  development of new products and features,  product quality
and  performance,  the quality and  experience  of sales,  marketing and service
organizations,  product  price and name  recognition.  Many of these factors are
beyond the Company's control.

         The Company's  competitors in the information  security markets include
Security  Dynamics,   Semaphore,  Cray  Research,   Racal-Guardata,   Inc.,  and
Information Resource Engineering,  Inc. Northern Telecom Limited, AT&T, Motorola
Corporation,  Digital  Equipment  Corporation and Sun  Microsystems,  Inc. offer
certain  information  security  products  as part of  their  overall  networking
solutions.  In addition,  a number of significant  vendors,  including Microsoft
Corporation,   Netscape  Communications  Corporation  and  Cisco  have  embedded
security  solutions  in their  software.  To the extent  that these  embedded or
optional  security  capabilities  provide all or a portion of the  functionality
provided by the  Company's  products,  the  Company's  products may no longer be
required by customers to attain information security.

         RSA Data Security, Inc., a subsidiary of Security Dynamics, ("RSA DSI")
licenses various methods of implementing Public Key cryptography, including some
that are  different  than (and  incompatible  with) the  method of  implementing
Public Key  cryptography  currently used by the Company in most of its products.
Although  Cylink has a license to use all of the Public Key methods  promoted by
RSA DSI, to the extent relevant  industries impose technical standards different
than  those  currently  used by the  Company in any  segment of the  information
security  market,  sales of the Company's  existing and planned products in that
market segment may be adversely  impacted,  which could have a material  adverse
effect on the Company's financial condition and results of operations.


                                       13
<PAGE>

         The Company  competes  with a large number of companies in the wireless
communications  markets,  including  U.S.  local  exchange  carriers and foreign
telephone  companies.  The most significant  competition for sub-T1 rate AirLink
products in the wireless  market is from  telephone  companies that offer leased
line data services.  The Company also competes with other  suppliers of wireless
products such as Digital  Wireless,  Utilicom,  Western Multiplex and California
Microwave, Inc.

         Many of the Company's competitors have substantially greater financial,
technical, marketing, distribution and other resources, greater name recognition
and longer standing  relationships with customers than the Company.  Competitors
with greater  financial  resources are better able to engage in sustained  price
reductions  in order  to gain  market  share.  Any  period  of  sustained  price
reductions  would  have a material  adverse  effect on the  Company's  financial
condition and results of operations.  There can be no assurance that the Company
will be able to compete successfully in the future or that competitive pressures
will not materially and adversely affect the Company's  financial  condition and
results of operations.

Product Liability Risks

         Customers  rely  on the  Company's  information  security  products  to
prevent  unauthorized  access  to  their  networks  and  data  transmissions.  A
malfunction or the inadequate  design of the Company's  products could result in
tort or warranty  claims.  Although  the Company  attempts to reduce the risk of
such losses through warranty disclaimers and liability limitation clauses in its
sales agreements and by maintaining product liability insurance, there can be no
assurance  that such  measures  will be  effective  in  limiting  the  Company's
liability  for any such  damages.  Any  liability  for  damages  resulting  from
security  breaches could be substantial and could have a material adverse effect
on  the  Company's   business  and  results  of  operations.   In  addition,   a
well-publicized  actual or perceived  security breach could adversely affect the
market's  perception of security products in general,  or the Company's products
in  particular,  regardless  of  whether  such  breach  is  attributable  to the
Company's  products.  This could result in a decline in demand for the Company's
products,  which would have a material adverse effect on the Company's financial
condition and results of operations.

Management of Growth

         The Company has recently  experienced  and may  continue to  experience
substantial  growth  in the  number  of  its  employees  and  the  scope  of its
operations,  resulting in increased  responsibilities for management.  To manage
growth   effectively,   the  Company  will  need  to  continue  to  improve  its
operational,  financial and management  information  systems and to hire, train,
motivate and manage a growing  number of employees.  Competition  is intense for
qualified  technical,  marketing and management  personnel,  particularly highly
skilled  engineers.  In  particular,   the  current  availability  of  qualified
engineers  is  quite  limited,   and  competition   among  companies,   academic
institutions,  government  entities  and other  organizations  for  skilled  and
experienced  engineering  personnel  is very  intense.  The Company is currently
attempting to hire a number of engineering  personnel and has experienced delays
in  filling  such  positions.   The  Company  expects  to  experience  continued
difficulty  in filling its needs for qualified  engineers  and other  personnel.
There can be no assurance that the Company will be able to  effectively  achieve
or manage any  future  growth,  and its  failure  to do so could  delay  product
development  cycles or otherwise have a material adverse effect on the Company's
financial condition and results of operations.

Intellectual Property and Other Proprietary Rights

         The Company  relies on patents,  trademarks,  copyrights,  licenses and
trade secret law to establish and preserve its intellectual property rights. The
Company owns twelve U.S. patents covering certain aspects of its product designs
and has one additional U.S. patent application pending. The Company also has the
exclusive right to sublicense the Stanford  Patents,  which expire in the United
States in the third quarter of 1997.  There can be no assurance that any patent,
trademark,  copyright  or  license  owned  or held by the  Company  will  not be
invalidated, circumvented or challenged, that the rights granted thereunder will
provide  competitive  advantages  to the  Company  or that any of the  Company's
pending  or future  patent  applications  will be  issued  with the scope of the
claims sought by the Company, if at all. Further, there can be no assurance that
others  will not  develop  technologies  that are  similar  or  superior  to the
Company's  technology,  duplicate the Company's  technology or design around the
patents  owned by the  Company.  The Company  may be subject to or may  initiate
interference   proceedings  in  the  U.S.  Patent  Office,   which  can  require
significant financial and management resources. In addition, the laws of certain
countries in which the Company's products are or may be developed,  manufactured
or sold may not protect the Company's products and intellectual  property rights
to the same  


                                       14
<PAGE>

extent as the laws of the United States. The inability of the Company to protect
its intellectual property adequately could have a material adverse effect on its
financial condition and results of operations.

         The network information security and wireless communications industries
in which the  Company  sells  its  products  are  characterized  by  substantial
litigation regarding patent and other intellectual property rights. From time to
time, the Company has received  communications from third parties asserting that
the Company's patents,  features or content of certain of the Company's products
infringe upon the  intellectual  property rights held by third parties,  and the
Company may receive such  communications in the future. The Company is not aware
that any of the features or content of its products  wrongfully  infringe on any
valid  intellectual  property  rights of others.  There can be no assurance that
third  parties  will not  assert  claims  against  the  Company  that  result in
litigation.  Any litigation,  whether or not determined in favor of the Company,
could result in significant  expense to the Company and could divert  management
and  other  resources.  In the  event of an  adverse  ruling  in any  litigation
involving  intellectual  property,  the Company might be required to discontinue
the use of certain processes, cease the manufacture,  use and sale of infringing
products,  expend significant resources to develop non-infringing  technology or
obtain licenses to the infringing technology and may suffer significant monetary
damages,  which could include  treble  damages.  There can be no assurance  that
under  such  circumstances  a  license  would be  available  to the  Company  on
reasonable  terms or at all.  In the event of a  successful  claim  against  the
Company and the Company's failure to develop or license a substitute  technology
on commercially  reasonable terms, the Company's financial condition and results
of  operations  would be  adversely  affected.  There can be no  assurance  that
existing claims or any other  assertions (or claims for indemnity from customers
resulting from infringement claims) will not materially and adversely affect the
Company's financial condition and results of operations.

Evolving Information Security Market

         The market for the  Company's  information  security  products  is only
beginning  to  emerge.   This  market  is   characterized  by  rapidly  changing
technology,  emerging industry standards,  new product introductions and changes
in customer  requirements  and  preferences.  The Company's  future success will
depend in part upon end  users'  demand for  information  security  products  in
general,  and upon the Company's ability to enhance its existing products and to
develop  and  introduce  new  products  and  technologies   that  meet  customer
requirements.   Any   significant   advance  in   technologies   for   attacking
cryptographic systems could render some or all of the Company's existing and new
products  obsolete or  unmarketable.  To the extent that a specific method other
than the  Company's  is adopted as the  standard  for  implementing  information
security  in any  segment  of the  information  security  market,  sales  of the
Company's  existing and planned products in that market segment may be adversely
impacted,  which could have a material adverse effect on the Company's financial
condition and results of operations.  There can be no assurance that information
security-related products or technologies developed by others will not adversely
affect the Company's competitive position or render its products or technologies
noncompetitive or obsolete.

         In  addition,  a  portion  of the  sales of the  Company's  information
security  products  will depend upon a robust  industry and  infrastructure  for
providing access to public switched networks, such as the Internet. There can be
no assurance that the infrastructure or complementary products necessary to make
these networks into viable  commercial  marketplaces  will be developed,  or, if
developed, that these networks will become viable commercial marketplaces.

Rapid Technological Change

         The markets for the  Company's  products are  characterized  by rapidly
changing  technologies,  extensive research and new product  introductions.  The
Company believes that its future success will depend in part upon its ability to
continue to enhance its existing products and to develop, manufacture and market
new products. As a result, the Company expects to continue to make a significant
investment in engineering,  research and development.  There can be no assurance
that  the  Company  will  be able to  develop  and  introduce  new  products  or
enhancements to its existing  products in a timely manner which satisfy customer
needs, achieve market acceptance or address  technological changes in its target
markets.  The  failure of the Company to develop  products  and  introduce  them
successfully  and in a  timely  manner  could  adversely  affect  the  Company's
competitive position, financial condition and results of operations.

Wireless Communications Industry Regulatory Environment

         Wireless communications are subject to regulations by United States and
foreign laws and  international  treaties.  In the United States,  the Company's
wireless  communications products are subject to various regulations of the FCC.
Current FCC regulations permit  license-free  operation of certain FCC certified
wireless  products.  The  future of  remote  


                                       15
<PAGE>

wireless  communications is highly volatile,  due in part to ongoing uncertainty
regarding telecommunications deregulation and the status of initiatives relating
to  the  auction  of  licenses  for  personal   communications  service  ("PCS")
frequencies.   Regulatory  changes,  including  changes  in  the  allocation  of
available  frequencies,  could significantly  affect the Company's operations by
diverting the Company's development efforts, making current products obsolete or
increasing the opportunity for additional competition. There can be no assurance
that new regulations will not be promulgated which could have a material adverse
effect on the Company's financial condition and results of operations.

         The  Company  also is subject  to  regulatory  requirements  in foreign
markets.  Equipment  can be marketed in a country  only if permitted by suitable
frequency  allocations and regulations,  and only if such equipment has received
type  approval by the country in  question.  The process of  complying  with new
regulations  and of obtaining type approval is often complex and lengthy and can
result in significant  expense and delays in the introduction of products in new
countries.

         Changes in, or the failure by the  Company to comply  with,  applicable
domestic and  international  regulations could have a material adverse effect on
the Company's business and operating results. There can be no assurance that the
Company will be able to comply with regulations in any particular country.

Risks  Associated  with  International  Sales;  Reliance  Upon  Local  Partners;
Restrictions on Export

         International product sales represented  approximately 35%, 47% and 59%
of revenue in 1994,  1995 and 1996,  respectively.  In particular,  sales of the
Company's  wireless   communications  products  are  currently  concentrated  in
developing countries.  The Company plans to continue to expand its foreign sales
channels  and to enter  additional  international  markets,  both of which  will
require significant management attention and financial resources.  International
sales  are  subject  to a number  of  risks,  including  unexpected  changes  in
regulatory  requirements,  tariffs  and  other  trade  barriers,  political  and
economic   instability  in  foreign  markets,   difficulties  in  the  staffing,
management and integration of foreign operations, longer payment cycles, greater
difficulty  in  collecting  accounts  receivable,   currency   fluctuations  and
potentially adverse tax consequences.  Since most of the Company's foreign sales
are  denominated  in U.S.  dollars,  the  Company's  products  become less price
competitive in countries in which local currencies  decline in value relative to
the U.S. dollar. The uncertainty of monetary exchange values has caused, and may
in the future cause, some foreign customers to delay new orders or delay payment
for existing  orders.  The long-term impact of such  devaluation,  including any
possible effect on the business outlook in other developing countries, cannot be
predicted.

         The Company's  ability to compete  successfully in foreign countries is
dependent  in part on the  Company's  ability to obtain and retain  reliable and
experienced  in-country  distributors and other strategic partners.  The Company
does not have  long-term  relationships  with any of its  value-added  resellers
("VARs")  and  distributors  and,  therefore,  has no  assurance of a continuing
relationship within a given market.

         United  States  government  regulations  restrict the export of certain
cryptographic  devices,  including certain of the Company's information security
products.  As a result,  the Company may be at a  disadvantage  in competing for
international sales compared to companies located outside the United States that
are not subject to such restrictions.

Dependence  on  Component  Availability,   Subcontractor   Performance  and  Key
Suppliers

         The Company's  ability to timely deliver its products is dependent upon
the  availability  of quality  components and subsystems used in these products.
The Company depends in part upon  subcontractors  to  manufacture,  assemble and
deliver certain items in a timely and satisfactory  manner.  The Company obtains
certain  components and subsystems from single, or a limited number of, sources.
A significant  interruption  in the delivery of such items could have a material
adverse effect on the Company's financial condition and results of operations.


ITEM 2.  PROPERTIES

         The Company's  headquarters  occupies  86,000 square feet in Sunnyvale,
California,  the lease for which expires in June 1999. During the second quarter
of 1996, the Company signed a five-year lease agreement for approximately 35,000
square feet of office and manufacturing space, also in Sunnyvale.  Substantially
all  manufacturing  activities  have been moved to this site. The Company leases
facilities for sales offices in New Jersey, Virginia, United Kingdom, Singapore,
China, India and Pakistan.  The Company believes that its current facilities are
well  maintained and are adequate for the  



                                       16
<PAGE>

foreseeable  future and that suitable  additional or  alternative  space will be
available in the future on commercially reasonable terms as needed.


ITEM 3.  LEGAL PROCEEDINGS

         On  September  6, 1995,  the  Company  obtained  an  arbitration  award
dissolving a former partnership,  known as Public Key Partners ("PKP"),  between
the  Company's  wholly-owned  subsidiary,  Caro-Kann  Corporation,  and RSA DSI.
Although various claims between the Company and RSA DSI were settled on December
31, 1996, a third party  continues to pursue  various claims against PKP and RSA
DSI for wrongful  business  practices in action  C-94-20512 SW before the United
States  District Court for the Northern  District of California.  An unfavorable
outcome might affect the residual  value the Company may receive from the former
partnership.

         On March 7, 1997,  ten former  employees  of the Company  filed suit in
action No. CV764647 in the Superior Court of California,  County of Santa Clara,
against the Company,  each of its Directors and its General  Counsel,  asserting
claims for wrongful  termination,  fraud,  libel,  slander,  age discrimination,
invasion of privacy,  and  violation of the federal RICO  statute.  Although the
Company  has placed its  insurers on notice of these  claims,  none of them have
admitted coverage. The Company believes the terminations were lawful and intends
to defend  the  matter  vigorously.  The  defense  of this  matter  may divert a
material  amount of  management's  attention  and  require  the  expenditure  of
significant  legal fees and costs.  An  unfavorable  outcome  which  exceeds the
Company's  insurance  coverage,  if any,  may also result in a material  adverse
effect on the Company's financial condition.


ITEM 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

         No  matters  were  submitted  to a vote of  security  holders,  through
solicitation  of proxies or otherwise,  during the fourth  quarter of the fiscal
year covered by this report.

The  following  table sets forth  certain  information  regarding  the Company's
information security products and wireless communications products:

                                                      Year ended December 31,
                                                   -----------------------------
                                                   1996         1995       1994

                                                     (dollars in thousands)
Information security product revenue              $25,793    $21,534    $18,008
Information security product gross margin              62%        67%        66%

Wireless communications product revenue           $26,165     13,368      8,638
Wireless communications product gross margin           54%        49%        50%


         Revenue. The Company's revenue increased 49% from $34.9 million in 1995
to $52.0 million in 1996.  Sales of information  security  products and wireless
communications  products  increased by 20% and 96%,  respectively,  from 1995 to
1996. The increased revenue from information security products was primarily due
to increased unit sales of the Company's  Secure WAN, LAN and Access  encryption
product line, which are used in public and private linked  networks.  Unit sales
of the Company's older CIDEC  encryption  product line were  essentially flat in
comparison  with  1995.  The  increased  revenue  from  wireless  communications
products  was  primarily  a  result  of  significantly  increased  shipments  in
international markets.

         The Company's revenue increased 31% from $26.6 million in 1994 to $34.9
million  in  1995.   Sales  of  information   security   products  and  wireless
communications  products  increased by 20% and 55%,  respectively,  from 1994 to
1995.  These  increases were primarily due to higher unit sales of the Company's
existing products.


                                       20
<PAGE>

         International product revenue was 35%, 47% and 59% of revenue for 1994,
1995 and 1996,  respectively.  International  product revenue as a percentage of
total   revenue   increased   for  both   information   security   and  wireless
communications products in 1995 and 1996, but the overall increase was primarily
due to increased unit sales of wireless communications products.

         Gross Profit.  Gross profit increased 43% from $21.1 million in 1995 to
$30.2 million in 1996, but decreased  slightly as a percentage of sales from 60%
to 58%. As a  percentage  of revenue,  gross profit was  negatively  affected by
increased  sales of wireless  communications  products,  which  generally have a
lower gross margin than information security products.  Further, gross margin on
information  security  products  declined as some of the new products have lower
gross margins than the Company's older CIDEC  encryption  products and these new
products represented an increased percentage of revenue.  This decrease in gross
margin was  partially  offset by an overall  increase in wireless  communication
product gross margins due to increased  average  selling prices and reduced unit
costs.

         Gross profit  increased 31% from $16.2 million in 1994 to $21.1 million
in 1995  primarily  due to increased  unit volume.  As a percentage  of revenue,
gross profit  decreased  marginally  from 1994 to 1995 due to increased sales of
wireless communications products.

         Research and  Development.  Research and development  expenses  consist
primarily  of salaries and other  personnel-related  expenses,  depreciation  of
development equipment,  facilities and supplies.  Gross research and development
expenses  increased  28% from $8.8 million in 1994 to $11.3  million in 1995 and
54% to  $17.4  million  in  1996.  From  time  to  time,  the  Company  receives
engineering  funding for development  projects to apply or enhance the Company's
technology to a particular  customer's need. The amounts  recognized under these
research and development  contracts are offset against  research and development
expense.  Amounts recognized under non-recurring  engineering  contracts totaled
$0.7  million,   $1.1  million  and  $6.1  million  in  1994,   1995  and  1996,
respectively.

         Selling and Marketing. Selling and marketing expenses consist primarily
of personnel  costs,  including  sales  commissions,  and costs of  advertising,
public  relations,  seminars and trade  shows.  Selling and  marketing  expenses
increased 47% from $6.5 million in 1994 to $9.6 million in 1995 and 44% to $13.8
million in 1996. The increases were  primarily due to expenses  associated  with
expansion  of the  Company's  direct  sales  force,  personnel  increases in the
marketing  group,  and  increased  costs  associated  with  advertising,  public
relations and trade shows.

         General and Administrative. General and administrative expenses consist
primarily of personnel  and related  costs,  recruitment  expenses,  information
system costs, and audit, legal and other professional  service fees. General and
administrative  expenses increased 23% from $4.1 million in 1994 to $5.0 million
in 1995 and 23% to $6.2 million in 1996. General and administrative expense as a
percentage  of  revenue  was  15%,  14%  and  12%  for  1994,   1995  and  1996,
respectively.  The  dollar  increases  in 1995  and 1996  are  primarily  due to
increased  staffing and  professional  fees  necessary to manage and support the
Company's  recent  growth  and  provide  infrastructure  required  for a  public
company.  The  decreases  as a  percentage  of  revenue  in 1995 and  1996  were
primarily due to general and  administrative  expenses  allocated  over a larger
revenue base.

         Employee  Severance  Costs.  During  the fourth  quarter  of 1996,  the
Company recorded a $634,000  one-time charge related to the  reorganization  and
replacement of several senior management positions.

         Other Income  (Expense),  Net.  Other income  (expense),  net primarily
consists of  royalties,  interest  income and  interest  expense.  Other  income
increased  33% from $1.4 million in 1994 to $1.9 million in 1995 and 73% to $3.2
million in 1996.  The  increase  in 1995 was  primarily  due to an  increase  in
royalty  income  partially  offset by a decrease in interest  and other  income.
Royalty income in 1994 and 1995 included  royalty payments from two licensees of
the Company's  wireless ASIC products for cordless  telephones.  The increase in
other  income for 1996 was  principally  due to an increase  in interest  income
resulting  from funds  derived from the  Company's  initial  public  offering in
February and March 1996.  The Company  sustained a decrease in royalty income in
1996  from  the  aforementioned  licensees.   Additionally,   the  Company  sold
marketable securities at a loss of $432,000 in 1996.

         Provision  (Benefit)  for Income  Taxes.  The  provision  (benefit) for
income taxes as a percentage  of income (loss) before taxes was a benefit of 39%
in 1994, a benefit of 41% in 1995 and a provision  of 17% in 1996.  Net deferred
tax  assets of $1.4  million  at  December  31,  1996,  were  based  both on the
Company's  carryback  capacity and management's  determination  that the Company
will more likely than not realize such assets based on expected future income in
the next

twelve  months.  However,  there can be no  assurance  that the Company  will be
profitable  in future  periods.  See Item I  "Business - Risk  Factors  That May
Affect Future  Results -- Recent  Losses;  Potential  Fluctuations  in Operating
Results,  Future Operating Results  Uncertain." The Company's effective tax rate
for 1997 is expected to increase to approximately the federal statutory rate.

         Net income (loss).  The Company had losses of $700,000 in 1994 and $1.1
million in 1995,  and net income of $1.2 million in 1996.  In 1994,  the Company
began a  strategic  research  and  development  program  designed  to create new
products and enhance  existing  products.  While revenue  increased in 1995, the
Company  incurred  a net loss due to  continued  high  levels  of  research  and
development expenses related to the Company's strategic research and development
project.  In 1996,  increased  gross  profit  resulting  from newer  information
security products and international  sales of wireless  communications  products
was largely  offset by higher  spending for research and  development,  net, and
selling and marketing resulting in a loss from operations.

LIQUIDITY AND CAPITAL RESOURCES

         In February and March 1996,  the Company  completed its initial  public
offering and its Common Stock began trading on the Nasdaq  National Market under
the symbol CYLK.  Through the offering the Company sold 5,750,000  shares of its
Common  Stock  which  generated  approximately  $79.3  million  in cash,  net of
underwriting discounts, commissions and other offering costs. As of December 31,
1996, the Company had $78.8 million in cash and cash equivalents.

         Cash provided by operating  activities in 1994 consisted primarily of a
decrease  in  accounts  receivable  and  increases  in accrued  liabilities  and
deferred  revenue,  offset in part by a net loss and an increase in inventories.
Cash used in operating  activities  for 1995 was  principally  a result of a net
loss and  increased  inventory  and  accounts  receivable  to support  increased
revenue,  which were offset only in part by  increases  in accounts  payable and
accrued liabilities. Cash used in operating activities in 1996 was principally a
result of increased  inventory  and  accounts  receivable  to support  increased
revenue,  which was  offset in part by net  income  and  increases  in  accounts
payable and accrued liabilities.

         The Company made capital  expenditures of  approximately  $1.2 million,
$614,000 and $2.8 million in 1994, 1995 and 1996, respectively. Additionally, in
1995 and 1996 the Company acquired  $493,000 and $256,000 of equipment  financed
by capital  leases.  These  acquisitions  have  generally  consisted of computer
workstations,   networking  equipment,   office  furniture  and  equipment,  and
leasehold additions and improvements.  In 1994, the Company purchased marketable
securities of $2.8 million. These securities were sold in 1994 and 1996.

         The Company  believes that  existing  cash balances and cash  generated
from  operations  will be  sufficient  to fund  necessary  purchases  of capital
equipment and to provide working capital through 1997. However,  the Company may
require  additional  funds to support its working  capital  requirements  or for
other  purposes and may seek to raise such  additional  funds through  public or
private equity  financing or from other sources.  No assurance can be given that
additional financing will be available or that, if available,  will be available
on  terms  favorable  to the  Company  or its  shareholders.  See  Item 3 "Legal
Proceedings"  and  Item 1  "Business  - Risk  Factors  That  May  Affect  Future
Results."

                        Report of Independent Accountants

        To the Board of Directors and Shareholders of
          Cylink Corporation

        In our opinion,  the  consolidated  financial  statements  listed in the
        above index  present  fairly,  in all material  respects,  the financial
        position of Cylink Corporation and its subsidiaries at December 31, 1996
        and 1995,  and the results of their  operations and their cash flows for
        each of the three  years in the  period  ended  December  31,  1996,  in
        conformity  with  generally  accepted   accounting   principles.   These
        financial statements are the responsibility of the Company's management;
        our   responsibility  is  to  express  an  opinion  on  these  financial
        statements  based  on our  audits.  We  conducted  our  audits  of these
        statements in accordance  with  generally  accepted  auditing  standards
        which  require  that we plan and perform the audit to obtain  reasonable
        assurance  about whether the financial  statements  are free of material
        misstatement.  An audit includes  examining,  on a test basis,  evidence
        supporting  the amounts and  disclosures  in the  financial  statements,
        assessing the accounting  principles used and significant estimates made
        by  management,   and  evaluating   the  overall   financial   statement
        presentation.  We believe that our audits provide a reasonable basis for
        the opinion expressed above.

Cylink Corporation
Notes to Consolidated Financial Statements


1.   The Company and a Summary of its Significant Accounting Policies

     The Company

         Cylink  Corporation  (the "Company") was  incorporated in California in
     October  1989  to  engage  in the  development,  manufacture,  license  and
     marketing of  electronic  encryption  devices and in 1990 began  developing
     wireless communication products.

         The Company's operations outside of the United States consist primarily
     of a sales office in the United Kingdom.

     Basis of presentation

         The  consolidated  financial  statements  include  the  accounts of the
     Company and its  subsidiaries.  All significant  intercompany  accounts and
     transactions have been eliminated.

         The Company's  interim  quarters end on the Friday nearest the calendar
     quarter end. The Company's year end is December 31.

     Foreign currency

         The functional currencies of the Company's foreign subsidiaries are the
     local  currencies.  The balance sheet accounts are  translated  into United
     States  dollars at the exchange rate  prevailing at the balance sheet date.
     Revenues,  costs and expenses are translated  into United States dollars at
     average rates for the period.  Gains and losses  resulting from translation
     are presented as a component of shareholders'  equity. Net gains and losses
     resulting  from  foreign   exchange   transactions   are  included  in  the
     consolidated statement of operations and were not significant during any of
     the periods presented.

     Cash equivalents and short-term investments

         Cash equivalents consist of highly liquid investment instruments with a
     maturity at the time of purchase of three months or less.

         The    Company's    short-term    investments    are    classified   as
     available-for-sale and therefore are reported at fair value with unrealized
     gains and losses as a separate component of shareholders' equity.

     Inventories

         Inventories   are  stated  at  the  lower  of   standard   cost  (which
     approximates actual cost on a first-in, first-out basis) or market.

     Other assets

         Patent  acquisition costs are amortized using the straight-line  method
     over 10 years.  Patents,  net of  amortization,  of $18,000 and $27,000 are
     included in other assets as of December 31, 1996 and 1995, respectively.

     Property and equipment

         Property and equipment are recorded at cost.  Depreciation  is computed
     using the  straight-line  method  over the  estimated  useful  lives of the
     assets,  generally five years.  Amortization  of leasehold  improvements is
     computed using the  straight-line  method over the shorter of the estimated
     useful lives of the assets or the remaining lease term.

     Revenue recognition

         Revenue is  recognized  upon  shipment to  customers.  Concurrently,  a
     provision is made for estimated  cost to repair or replace  products  under
     warranty  arrangements.  Revenue from sales to  distributors  is recognized
     upon shipment;  no right of return,  stock rotation or price  protection is
     given.  Revenue  from sales to value added  resellers  is  recognized  upon
     shipment and concurrently a provision for estimated returns is recorded.

         Royalty  income of  $1,308,000,  $1,772,000  and $866,000 for the years
     ended December 31, 1996, 1995 and 1994, respectively,  is included in other
     income and is  generally  recognized  upon the  reported  sale of  products
     subject to royalties.

     Research and development

         Research and  development  costs are charged to operations as incurred.
     The  Company on  occasion  receives  nonrecurring  engineering  funding for
     development  projects to apply or enhance  the  Company's  technology  to a
     particular  customer's needs.  Non-refundable  receipts are recognized over
     the term of the  respective  contract  using the  percentage  of completion
     method.  Receipts,  which are refundable pending the achievement of certain
     results,  are deferred and  recognized  upon  acceptance  by the  customer.
     Amounts  billed  on  contracts  and  collected  prior to being  earned  are
     recorded as deferred revenue. At the time of recognition,  amounts received
     under research and  development  contracts are offset against  research and
     development expenses.

         Software development costs are included in research and development and
     are expensed as incurred.  Statement of Financial  Accounting Standards No.
     86 (SFAS 86) requires the  capitalization  of certain software  development
     costs once  technological  feasibility  is  established,  which the Company
     defines as  completion of a working  model.  The  capitalized  cost is then
     amortized on a straight-line  basis over the estimated  product life, or on
     the  ratio  of  current  revenues  to  total  projected  product  revenues,
     whichever is greater.  To date, the period between achieving  technological
     feasibility  and the general  availability  of such software has been short
     and software  development  costs  qualifying for  capitalization  have been
     insignificant.  Accordingly,  the Company has not  capitalized any software
     development costs.

     Stock-based compensation

         The Company  accounts for stock based  compensation using the intrinsic
     value method  prescribed in Accounting  Principles  Board Opinion (APB) No.
     25,   "Accounting   for   Stock   Issued   to   Employees,"   and   related
     Interpretations.  The Company provides  additional pro forma disclosures as
     required  under  Statement of Financial  Accounting  Standard No. 123 (SFAS
     123), "Accounting for Stock-Based Compensation." See Note 7.

     Income taxes

         Deferred tax assets and liabilities are recognized for the expected tax
     consequences of temporary  differences  between the tax bases of assets and
     liabilities and their financial statement reported amounts.

     Net income (loss) per share

         Net income  (loss) per share is  computed  using the  weighted  average
     number of outstanding  shares of common stock and common stock equivalents.
     Common stock equivalents consist of stock options (using the treasury stock
     method).  Common stock  equivalents  are excluded from the  computation  if
     their effect is antidilutive,  except that, pursuant to the requirements of
     the Securities and Exchange Commission, common stock equivalents (using the
     treasury  stock  method  and the  initial  public  offering  price)  issued
     subsequent  to  November  30,  1994  through  February  15,  1996 have been
     included in the  computation  as if they were  outstanding  for all periods
     through the effective date of the Company's initial public offering.

     Off-balance sheet risk and concentrations of credit risk

         Financial   instruments  that   potentially   subject  the  Company  to
     significant concentration of credit risk consist primarily of cash and cash
     equivalents,  short-term investments,  accounts receivable, and to a lesser
     extent  currency  fluctuation of balances  denominated in currencies  other
     than the United States dollar.  The Company limits the amount of investment
     exposure to any one financial  institution  and financial  instrument.  The
     Company  performs  on-going credit  evaluations and maintains  reserves for
     potential credit losses; historically such losses have been 


                                       29
<PAGE>

     immaterial.  The Company minimizes the amount of cash it maintains in local
     currencies by maintaining excess cash in United States dollars.

         No customer accounted for more than 10% of total accounts receivable at
     December 31, 1996 and 1995 and no customer  accounted  for greater than 10%
     of revenue in any period presented.

     Use of estimates

         The  preparation of financial  statements in conformity  with generally
     accepted  accounting  principles  requires management to make estimates and
     assumptions  that affect the reported amounts of assets and liabilities and
     disclosure  of  contingent  assets  and  liabilities  at  the  date  of the
     financial statements,  and reported amounts of revenues and expenses during
     the reporting period. Actual results could differ from those estimates.

     Reclassifications

         Certain amounts in the 1995 financial statements have been reclassified
     to conform to the 1996 presentation.

     Dependence on suppliers

         The Company's  ability to timely deliver its products is dependent upon
     the  availability  of  quality  components  and  subsystems  used in  these
     products.  The Company depends in part upon  subcontractors to manufacture,
     assemble and deliver certain items in a timely and satisfactory manner. The
     Company obtains certain components and subsystems from single, or a limited
     number of sources. A significant interruption in the delivery of such items
     could have a material adverse effect on the Company's  financial  condition
     and results of operations.

2.   Initial Public Offering

         In February 1996, the Company completed its initial public offering and
     issued  5,000,000  shares of its  common  stock to the public at a price of
     $15.00 per share. In March 1996, the underwriters exercised their option to
     cover over-allotments and an additional 750,000 shares of common stock were
     issued at $15.00 per share. The Company received  approximately $79 million
     of cash,  net of  underwriting  discounts,  commissions  and other offering
     costs.

     In connection  with the Company's  initial  public  offering,  the Board of
     Directors authorized the issuance of up to 5,000,000 shares of undesignated
     preferred  stock and the Board has the authority to issue the  undesignated
     preferred  stock in one or more series and to fix the rights,  preferences,
     privileges and restrictions  thereof. No preferred stock had been issued as
     of December 31, 1996.

4.   Short-term Investments

         The cost and fair value of the Company's  short-term  investments as of
     December 31, 1995 were as follows (in thousands):


                                                                   Unrealized

         Short-term  investments generally consisted of preferred stock and were
     sold  during  1996  resulting  in a loss of  $432,000.  The  Company had no
     short-term investments as of December 31, 1996.

5.   Bank Line of Credit

         In July 1995, the Company  signed a credit  agreement with a bank which
     provided a line of credit for working capital  advances of up to $5,000,000
     or a specified percentage of eligible accounts receivable,  plus $2,000,000
     or a specified  percentage of  short-term  investments,  respectively.  Any
     advances under the line of credit were  collaterized  by certain assets and
     intellectual property of the Company. Interest on borrowings under the line
     of credit was set at the 30 day LIBOR plus 2.0%.  Among  other  provisions,
     the  Company  was  required to maintain  certain  financial  


                                       31
<PAGE>

     covenants.  In addition,  payment of cash dividends was prohibited  without
     the bank's  consent.  At December  31,  1995,  the  Company had  $1,000,000
     outstanding under the line of credit which was repaid during 1996. The line
     of  credit  agreement  expired  in July  1996  and was not  renewed  by the
     Company.

6.   Income Taxes

         The provision (benefit) for income taxes consists of the following:

<PAGE>

         Net deferred tax assets of  $1,420,000  at December 31, 1996 were based
     on the Company's  carryback capacity and expected future income in the next
     twelve months.  Based on the available  objective  evidence,  including the
     operating losses  experienced in recent years,  management  cannot conclude
     that it is more likely than not a portion of the  deferred  tax assets will
     be realized and,  therefore,  the Company has recorded a partial  valuation
     against the deferred tax assets.

         The provision  (benefit)  reconciles to the amount computed by applying
     the United States federal statutory rate to income before taxes as follows:

                                                     Year ended December 31,

         The Company has not provided  United States federal income taxes on the
     undistributed  earnings of foreign subsidiaries because it is the Company's
     intention to permanently reinvest such earnings. At December 31, 1996, 1995
     and  1994,  total   undistributed   earnings  of  these  subsidiaries  were
     approximately $1,846,000, $1,579,000 and $1,341,000, respectively.

         The Company had  research  and  development  credit  carry  forwards of
     approximately  $980,000  and  $1,200,000  at  December  31,  1996 and 1995,
     respectively, which expire from 2009 to 2010.


7.   Stock Option Plans

     The Company has  adopted the 1987 Stock  Option Plan and the 1994  Flexible
     Stock Incentive Plan (collectively  known as the "Plans") which provide for
     the grant of incentive  stock  options and  nonqualified  stock  options to
     executives,  employees  and  consultants  to purchase up to  2,010,000  and
     3,950,000  common  shares,  respectively.  Stock  options may be granted at
     prices  not less than 100% and 85% for  incentive  and  nonqualified  stock
     options, respectively, of the fair market value of the stock on the date of
     grant.  Through December 31, 1996, all nonqualified stock options have been
     granted at 100% of the fair market value of the stock on the date of grant.
     Options  granted  under the Plans are  exercisable  at such times and under
     such conditions as determined by the Board of Directors, and generally vest
     over five years. Options expire ten years from the date of grant.

     Shares issued upon exercise of options are subject to certain  restrictions
     on their  transferability.  The  Company has the right to  repurchase  such
     shares,  at a price equal to the fair market value, when the optionee is no
     longer associated with the Company.  Shares repurchased increase the number
     of shares available for grant under the Plans.

</TABLE>

         The weighted  average  estimated  grant date fair value,  as defined by
SFAS 123, for options granted during 1995 at market price and below market price
on the dates of grant were $1.04 and $1.47,  respectively.  The weighted average
estimated  grant date fair value, as defined by SFAS 123, for options granted at
market  price  during  1996 was  $6.03.  The  estimated  grant  date fair  value
disclosed  by the  Company is  calculated  using the  Black-Scholes  model.  The
Black-Scholes  model,  as well as  other  currently  accepted  option  valuation
models,  was  developed  to estimate the fair value of freely  tradeable,  fully
transferable  options without vesting  restrictions,  which significantly differ
from the  Company's  stock  option  awards.  These  models also  require  highly
subjective  assumptions,  including  future stock price  volatility and expected
time until exercise, which greatly affect the calculated grant date fair value.


                                       34
<PAGE>

         The  following  weighted  average   assumptions  are  included  in  the
estimated  grant date fair value  calculations  for the  Company's  stock option
awards:

                                                   1996                1995

Expected life (years)                               3.04                3.04
Risk-free interest rate                             5.93%               6.22%
Volatility                                         69.46%              54.89%
Dividend yield                                      0.00%               0.00%


         Had the Company  recorded  compensation  costs  based on the  estimated
     grant date fair value, as defined by SFAS 123, for awards granted under its
     stock option  plans,  the Company's net income (loss) and net income (loss)
     per share would have been  reduced to the pro forma  amounts  below for the
     years ended December 31, 1996 and 1995 (in thousands,  except for per share
     amounts):

                                                             1996        1995

Net income (loss)                     As reported          $ 1,197     $(1,079)
                                      Pro forma               (325)     (1,354)

Net income (loss) per share           As reported          $  0.05     $ (0.06)
                                      Pro forma              (0.01)      (0.07)


         The pro forma  effect on net income  (loss)  and net income  (loss) per
     share for 1996 and 1995 is not  representative  of the pro forma  effect on
     net income in future years because it does not take into  consideration pro
     forma compensation expense related to grants made prior to 1995.

         As of December 31, 1995,  the Company had granted  certain  options for
     the  purchase of common stock at less than the deemed fair market value and
     approximately  $417,000 of compensation expense is being amortized over the
     five-year vesting period of the options.

8.   Notes Receivable From Shareholders

         During  November  1995,  the Company  made loans  totaling  $515,000 to
     certain  employees  pursuant to the Company's 1994 Flexible Stock Incentive
     Plan.  The loans bear interest at 8.0% per annum and are secured by 427,000
     shares of the Company's  common stock.  The loans were due in November 1996
     or, if earlier,  upon the  borrower's  termination  of employment  with the
     Company.  During 1996, the Company extended the due dates on certain of the
     loans.  As of  December  31,  1996,  the  remaining  balance on these loans
     totaled $301,000 and is due in February 1997.

9.   Research and Development Contracts

         During the years ended  December 31, 1996,  1995 and 1994,  the Company
     performed   research  and  development  under  several   government  funded
     arrangements aggregating $3,777,000,  $526,000 and $297,000,  respectively.
     These contracts provide funding  (irrespective of the results) for research
     and development of certain cryptographic technologies which will be jointly
     owned by the Company and these government agencies.  Amounts received under
     these contracts are offset against research and development expenses.

         The Company  performed  research and  development  under  several other
     research and  development  contracts  which provide for the development and
     transfer of technology  in exchange for  development  funding.  The Company
     recorded as a reduction of research and  development  expenses  $2,363,000,
     $604,000 and $367,000 under such  arrangements  in the years ended December
     31, 1996, 1995 and 1994,  respectively.  The funds received under contracts
     in  progress,   included  in  deferred   revenue  pending   achievement  of
     milestones,  totaled  $1,050,000 as of December 31, 1995. No funds had been
     received under such  contracts in advance of the  achievement of milestones
     as of December 31, 1996.


                                       35
<PAGE>

         In 1991,  the Company  entered into an agreement  with a third party to
     partially fund research and  development  related to certain  cryptographic
     technology.  The  Company is required  to pay  royalties  of 5% on sales of
     products  developed  under this  research  project.  In  connection  with a
     contract  amendment in 1993, the Company  prepaid  royalties of $300,000 in
     exchange for limitations on total royalties,  not to exceed  $712,000.  The
     prepaid royalties were fully amortized as of December 31, 1995.


10.  Joint Venture and Contingencies

         On  September  6, 1995,  the  Company  obtained  an  arbitration  award
     dissolving  a former  partnership,  known as Public Key  Partners  ("PKP"),
     between the Company's wholly-owned subsidiary,  Caro-Kann Corporation,  and
     RSA DSI.  Although  various  claims  between  the  Company and RSA DSI were
     settled on December  31, 1996,  a third party  continues to pursue  various
     claims  against PKP and RSA DSI for wrongful  business  practices in action
     C-94-20512  SW before the United  States  District  Court for the  Northern
     District of California. Management believes that the ultimate resolution of
     this  matter  will not have a  material  adverse  effect  on the  Company's
     financial position or results of operations.

     Subsequent event (unaudited)

         On March 7, 1997,  ten former  employees  of the Company  filed suit in
     action No.  CV764647 in the Superior Court of  California,  County of Santa
     Clara, against the Company,  each of its Directors and its General Counsel,
     asserting  claims for wrongful  termination,  fraud,  libel,  slander,  age
     discrimination,  invasion of privacy,  and  violation  of the federal  RICO
     statute.  Although  the Company has placed its  insurers on notice of these
     claims,  none of them have  admitted  coverage.  The Company  believes  the
     terminations were lawful and intends to defend the matter  vigorously.  The
     defense  of this  matter  may  divert a  material  amount  of  management's
     attention and require the expenditure of significant  legal fees and costs.
     An unfavorable outcome which exceeds the Company's  insurance coverage,  if
     any,  may  also  result  in a  material  adverse  effect  on the  Company's
     financial  condition.   However,  management  believes  that  the  ultimate
     resolution  of this matter will not have a material  adverse  effect on the
     Company's financial position or results of operations.

12.  Lease Commitments

         The Company  leases its  headquarters  and  manufacturing  facility and
     sales offices under various  noncancelable  operating leases.  These leases
     expire at various  dates  through  June 2001 and  certain of the leases are
     renewable  for an additional  five years.  In addition to the minimum lease
     payments,  the Company is responsible  for  insurance,  repairs and certain
     other  operating  costs  under the terms of the leases.  The  Company  also
     leases  certain   equipment  under  long-term  lease  agreements  that  are
     classified as capital leases. These capital leases, which consist primarily
     of computer  equipment,  terminate at various  dates  through  2000.  Total
     equipment  acquired  under  these  capitalized  leases,  which  secure such
     borrowings,  was  $621,000  at cost and  $445,000  at net book  value as of
     December 31, 1996.

     capital leases are as follows (in thousands):

                                       OF
                               CYLINK CORPORATION,
                            a California Corporation

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



         The undersigned Harold S. Yang and Robert Fougner hereby certify that:

                  ONE:They  are the duly elected and acting Vice  President  and
Secretary,  respectively,  of Cylink Corporation,  a California corporation (the
"Corporation").

                  TWO:The Amended and Restated Articles of Incorporation of said
Corporation  are  amended  as  follows:  Article  Third  shall be amended in its
entirety to read as follows:

                  "THIRD: A. Classes of Stock. This Corporation is authorized to
                  issue two classes of shares,  designated "Preferred Stock" and
                  "Common   Stock."  The  total   number  of  shares  which  the
                  Corporation  is  authorized  to issue is  forty  five  million
                  (45,000,000)  shares.  Forty million (40,000,000) shares shall
                  be Common Stock, $.01 par value, (the "Common Stock") and five
                  million  (5,000,000) shares shall be Preferred Stock, $.01 par
                  value (the "Preferred Stock").

                                    B. Preferred Stock. The undesignated  shares
                  of Preferred Stock shall be issued from time to time in one or
                  more  series.  The Board of  Directors  is hereby  authorized,
                  within  the  limitations  and  restrictions  stated  in  these
                  Articles  of  Incorporation,  to fix or alter  the  individual
                  rights,  dividend  rate,  conversion  rights,  voting  rights,
                  rights  and  terms  of  redemption   (including  sinking  fund
                  provisions),  the redemption price or prices,  the liquidation
                  preference of any wholly unissued  shares of Preferred  Stock,
                  and the number of shares  constituting any such series and the
                  designation  thereof,  or any of  them,  and  to  increase  or
                  decrease the number of shares of any series  subsequent to the
                  issue of shares of that  series,  but not below the  number of
                  shares of such series then outstanding.  In case the number of
                  shares  of  any  series  shall  be so  decreased,  the  shares
                  constituting  such decrease shall resume the status which they
                  had

<PAGE>

                  prior to the adoption of the resolution  originally fixing the
                  number of shares of such series."



         Article Sixth shall be added to read as follows:


                  "SIXTH: A. Date Effective. This Article shall become effective
                  only when the Corporation shall become a "listed  corporation"
                  within  the  meaning  of Section  301.5(d)  of the  California
                  Corporations Code.

                           B. No Cumulative Voting. The election of directors by
                  the shareholders  shall not be by cumulative  voting.  At each
                  election of directors by the  shareholders,  each  shareholder
                  entitled  to  vote  may  vote  all  the  shares  held  by that
                  shareholder  for each of several  nominees  for director up to
                  the number of directors to be elected. The shareholder may not
                  cast more  votes for any  single  nominee  than the  number of
                  shares held by that shareholder."

         Article Seventh shall be added to read as follows:


                  "SEVENTH:  A.  Date  Effective.   This  Article  shall  become
                  effective  only when the  Corporation  shall  become a "listed
                  corporation"  within the  meaning of Section  301.5(d)  of the
                  California Corporations Code.

                                    B.  Classified  Board of  Directors.  For so
                  long as the  board of  directors  consists  of at  least  nine
                  directors,  the directors shall be divided into three classes,
                  designated  Class I, Class II and Class III.  Each class shall
                  consist,  as nearly as may be possible,  of one-third (1/3) of
                  the total number of directors constituting the entire Board of
                  Directors.  The initial  classes  shall be elected as follows:
                  Class I directors shall be elected for a one-year term,  Class
                  II directors for a two-year term and Class III directors for a
                  three-year   term.  At  each  succeeding   annual  meeting  of
                  shareholders,  successors to the class of directors whose term
                  expires at the annual meeting of shareholders shall be elected
                  for three-year  terms.  If the number of directors is changed,
                  any  increase  or  decrease  shall be elected  for  three-year
                  terms. If the number of directors is changed,  any increase or
                  decrease  shall be  apportioned  among  the  classes  so as to
                  maintain the number of directors in each class as nearly equal
                  as possible,  and any additional director of any class elected
                  to fill a vacancy  resulting  from an  increase  in such class
                  shall  hold  office for a term that  shall  coincide  with the
                  remaining  term of that class,  but in no case will a decrease
                  in the number of directors  shorten the term of any  incumbent
                  director.  A  director  shall  hold  office  until the  annual
                  meeting  for the year in which  his or her  term  expires  and
                  until his or her successor shall be elected and shall qualify,
                  subject,  however,  to prior death,  resignation,  retirement,
                  disqualification  or removal from office.  Except as otherwise
                  required by law,  any vacancy on the Board of  


<PAGE>

                  Directors  that  results  from an  increase  in the  number of
                  directors  and any  other  vacancy  occurring  in the Board of
                  Directors  shall be filled by a majority of the directors then
                  in office,  even if less than a quorum, or by a sole remaining
                  director. Any director elected to fill a vacancy not resulting
                  from an  increase  in the number of  directors  shall have the
                  same remaining term as that of his or her predecessor."

                  THREE:  The  foregoing  amendments  of  Amended  and  Restated
Articles of  Incorporation  have been duly approved by the Board of Directors of
the Corporation.

                  FOUR:  The  foregoing   amendments  of  Amended  and  Restated
Articles of  Incorporation  were duly  approved by the holders of the  requisite
number of shares of the  Corporation  in  accordance  with  Sections  902 of the
California  General  Corporation  Law;  the total number of  outstanding  shares
entitled to vote with respect to the foregoing  amendment was 19,029,490  shares
of  Common  Stock.  The  number  of  shares  voting  in favor  of the  foregoing
amendments  equaled or exceeded the vote  required,  such  required vote being a
majority of the outstanding shares of Common Stock.

Amendment  of Amended and  Restated  Articles of  Incorporation  this 9th day of

provided  that  the  Employment  Term  shall be  extended  (subject  to  earlier
termination as provided in Section 9 hereof) for additional one (1) year periods
(the "Additional Terms"),  unless, at least thirty (30) days prior to the end of
the  Original  Employment  Term  or any  Additional  Term,  the  Company  or the
Executive  has  notified  the other in writing  that the  Employment  Term shall
terminate at the end of the then current term. If and when this  Agreement is so
extended,  the term "Employment Term" used herein shall also refer to the 


                                       3
<PAGE>

period of such extension.  Notwithstanding  anything else herein, the provisions
of  Section  12,  13,  14 and 16  hereof  shall  survive  and  remain  in effect
notwithstanding  the  termination  of the  Employment  Term or a  breach  by the
Company or Executive of this Agreement or any of its terms.

                  3.       Compensation.

                           (a) As  compensation  for  his  services  under  this
Agreement,  the  Company  shall  pay  Executive  a salary  at a rate of at least
$300,000  per year ("Base  Salary").  Such Base Salary shall be payable in equal
installments  (not less  frequently  than monthly) and subject to withholding in
accordance with the Company's normal payroll practices.

                           (b)  Executive's  Base Salary may be increased by the
Board, in its sole discretion, from time to time.

                           (c) In addition to the Base Salary, for each calendar
year completed during the Employment Term, the Company shall pay to Executive an
annual bonus which shall not be less than  $100,000 per year,  provided that the
minimum annual bonus for the 1996 calendar year shall be prorated by multiplying
$100,000 by a fraction the  numerator of which is 


                                       4
<PAGE>

the number of days during 1996 that the  Executive  was  employed by the Company
and the  denominator  of which is 365. The Company shall pay fifty percent (50%)
of the minimum  annual  bonus in July of each  calendar  year of the  Employment
Term,  with the remainder of such year's minimum annual bonus paid in January of
the following  calendar year. Any annual bonuses beyond the annual minimum bonus
shall be discretionary  with the Board or a Committee  thereof (the "Committee")
and, if declared and paid,  shall be paid at such time as bonuses are  generally
paid or as otherwise determined by the Board or Committee.

                           (d) The  Company  shall pay  Executive  a  $2,000,000
special bonus in January 2001 if Executive remains continuously  employed by the
Company  through  December 31, 2000. The Company may offset against such special
bonus (after any applicable  taxes are withheld) any amounts owed the Company by
the Executive.

                           (e) The Company  shall  reimburse  Executive  for all
reasonable expenses incurred by him in the course of performing his duties under
this Agreement which are consistent  with the Company's  policies in effect form
time to time with respect to travel,  entertainment and other business expenses,
subject  to  the   Company's   requirements   with  respect  



                                       5
<PAGE>

to reporting and documentation of such expenses.

                  4.       Benefits and Fringes.

                           (a) During the Employment  Term,  Executive  shall be
entitled to (i) all benefits and fringes, if any, as are generally provided from
time to time by the Company to its senior executive officers, including, without
limitation,  any life,  medical  and  disability  insurance  plans and  pension,
incentive,  profit-sharing,  deferred  compensation  and  other  similar  plans,
practices, policies and programs, subject to the Executive's satisfaction of the
applicable eligibility requirements and with due credit against any annual bonus
plan or program for the minimum  annual  bonus set forth in Section 3(c) hereof,
and (ii)  such  other  benefits  and  fringes  set forth in this  Agreement.  In
addition,  the  Company  shall  reimburse  Executive  annually  during each full
calendar year during the  Employment  Term for the  reasonable  annual cost of a
policy of term life insurance in the amount of $1,250,000,  upon presentation of
evidence of payment of the premiums on such  policy.  To the extent a commercial
life  insurance  policy has not been  obtained,  the Company will  self-fund the
$1,250,000 life insurance policy for the sixty (60) day period commencing on the
Effective Date. In addition,  during the Original  Employment  Term, 



                                       6
<PAGE>

the Company shall  reimburse  Executive  annually during each full calendar year
during  the  Employment  Term for the  reasonable  annual  cost of a policy  for
additional term life insurance in the amount of the lesser of (i) $2,000,000, or
(ii)  the  outstanding  principal  of the  Loan  under  Section  6  hereof  (the
"Additional Life Insurance").  The foregoing  reimbursements  for life insurance
premiums shall, based on Executive's  representation  that he is in good health,
be limited to payment of only a reasonable  amount (which  includes,  but is not
limited to,  standard  premium  amounts).  The Company  shall  gross-up  for tax
purposes the deemed income to Executive for providing life insurance  under this
Section 4(a) such that the  economic  effect to Executive is the same as if such
insurance was provided to Executive on a non-taxable  basis. Such gross up shall
be in accordance with Section 19 hereof. The Executive shall grant the Company a
first security  interest through a collateral  assignment in the Additional Life
Insurance to secure the loan under Section 6 hereof.

                           (b) During the Employment Term, the Company shall, in
its discretion,  either pay Executive a monthly automobile allowance of $500, or
make  available to Executive an  automobile of the type provided to other senior
executives of the Company for his 


                                       7
<PAGE>

exclusive  use in  connection  with the  official  business  of the  Company and
incidental personal use. If an automobile is made available,  Executive shall be
responsible  for all costs  associated  with  garaging  and  operating  any such
automobile,  other than those costs arising out of the official  business of the
Company,  provided that the Company shall be  responsible  for  maintenance  and
insurance.  Executive  shall be  responsible  for any  income  tax  consequences
arising from the use of the automobile under this arrangement.

                           (c) No later  than  sixty  (60)  days  after  (i) the
Effective Date or (ii) any required increase in coverage hereunder,  and subject
to Executive  cooperating with the insurance company  underwriting  requirements
and being accepted for the policy coverage at not more than  reasonable  premium
rates (with  respect to (i) above) and at no more than one  hundred  twenty-five
percent  (125%) of standard  premium  rates (with  respect to (ii)  above),  the
Company  shall  provide,  during the  Employment  Term,  a long term  disability
coverage  policy or policies  for  Executive's  benefit in an amount equal to at
least  sixty-six  and  two-thirds  percent  (66 and 2/3%) of the  greater of (A)
$500,000 per annum,  or (B) the sum of Executive's  then current Base Salary and
minimum  annual bonus,  provided that the amounts in (A) or (B) above and/or the
percentage  



                                       8
<PAGE>

above  shall be limited or reduced  to the extent  that the  Company  after good
faith effort is unable to obtain such policy.  The long term  disability  policy
shall be based upon the same waiting  period  (which shall be no longer than six
(6) months) and  substantially the same terms as the Company's current long term
disability policies for its executives.

                           (d) The Company agrees to reimburse Executive for (i)
all  reasonable  expenses  incurred by Executive in moving any items of personal
property owned by Executive and his family from Connecticut to California,  (ii)
the reasonable  cost of up to three (3) one-person  round trip airfare trips per
month  from  Connecticut  to  California  (coach  class),  which  may be used by
Executive,  his spouse,  or any of his children,  until Executive  relocates his
family  to  California,  but in no event  for more  than one (1) year  after the
Effective  Date, and (iii) the  reasonable  cost of three (3) round trip airfare
trips for  Executive's  family from  Connecticut  to California  during the same
period as  specified  in (ii).  In  addition,  during  the  period  prior to his
relocation (but in no event for more than one (1) year from the Effective Date),
the Company shall provide a suitable apartment for Executive's use when he is at
the Company's  headquarters.  The Company shall also reimburse Executive for the
following reasonable costs:


                                       9
<PAGE>

                                (i) All reasonable  transaction costs associated
with Executive purchasing his new residence in the area of the Company's current
headquarters,  including, but not limited to, closing costs, inspections,  title
insurance,  reasonable  legal  expenses  (other  than  for any  litigation)  and
statutory expenses; and

                                (ii) All reasonable transaction costs associated
with  Executive  selling his current  principal  residence,  including,  but not
limited to, standard brokerage commissions, closing costs, legal expenses (other
than for any  litigation)  and statutory  fees,  but not any costs of repairing,
changing or decorating the residence  prior to, or as a condition of, selling or
any costs to pay off or bond any liens or judgments.

                  In addition,  the Company  shall gross up for tax purposes any
deemed income arising pursuant to the benefits provided under this Section 4(d),
including  this  sentence,  so that the economic  benefit is the same as if such
benefits  were  provided  on a  non-taxable  basis.  Such  gross  up shall be in
accordance with Section 19 hereof.

                  5.       Stock Options.

                  On November 6, 1996, the  Compensation  Committee of the Board
(the  "Compensation  Committee")  granted  Executive  non-qualified  options  to
purchase 1,000,000 


                                       10
<PAGE>

shares  of  Company  common  stock at an  exercise  price of $11.00  per  share,
pursuant and subject to the Company's  1994 Flexible  Stock  Incentive Plan (the
"Plan"),  provided that options to purchase  250,000 shares of such common stock
were conditioned on shareholder approval of an amendment to the Plan, adopted at
the Board  meeting  held on  November 6, 1996,  increasing  the number of shares
permitted to be issued  under the Plan and the number  permitted to be issued to
any individual.  The terms of the Options,  which will be set forth in an Option
agreement,  substantially  in the  form as set  forth in the  Option  agreement,
annexed  as Exhibit A hereto  (as  specifically  modified  by this  Section  5),
include that the Options (i) shall fully vest upon the occurrence of a Change in
Control of the Company  (as such term is  currently  defined in the Plan),  (ii)
shall be for a maximum  ten (10) year  term,  and (iii)  shall  vest and  become
exercisable  ratably  over a five (5) year  period on the last day of each month
during such period, if the Executive is employed on each vesting date,  provided
that the  initial  twenty  percent  (20%) of the  Options  shall not vest and be
exercisable until the first  anniversary of the grant. In addition,  the Options
will provide that in the event of a termination  of  Executive's  employment (i)
prior to the second  anniversary of the Effective Date without Cause or for Good
Reason, or (ii) as a result of 


                                       11
<PAGE>

the  Executive's  death or  Disability,  in addition  to any  Options  which are
already vested and exercisable,  the Executive's  Options shall vest, and become
immediately  exercisable for a period of three (3) months after such termination
(except in the case of a death or  Disability  termination,  in which case,  the
period will be one (1) year),  but in no event beyond the original  Option term,
with respect to 200,000 Options, or in the case of Disability,  100,000 Options.
Upon any other  termination,  the periods of exercise are those set forth in the
annexed form agreement.

                  6.       Relocation Loan; etc.

                           (a) In  connection  with the transfer of  Executive's
principal place of employment to California from Connecticut,  the Company shall
provide Executive with a five (5) year interest-free mortgage loan in the amount
of up to $2,400,000 for purposes of  Executive's  acquisition of a new principal
residence  (the "Loan").  The Loan shall not be for more than the purchase price
of the  residence  and shall  promptly  be  reduced to  $2,000,000  upon sale by
Executive of his residence in  Connecticut  (or, if Executive does not sell such
residence, within two (2) years after the making of the Loan). The Loan shall be
subject to, and governed by, the terms and  conditions  of a loan  agreement and
mortgage  between the Executive  and the 


                                       12
<PAGE>

Company,  which the parties shall enter into at the time the Executive purchases
the new residence.  The Company shall retain a first mortgage  security interest
in the  residence  during the term of the Loan.  The Loan is intended to satisfy
the requirements of Temporary Treasury  Regulation Section  1.7872-5T(c)(1)  and
the parties  hereto agree to execute such  documents as are  necessary to comply
therewith.

                           (b) In the  event  the  Original  Employment  Term is
renewed,  (i) the Loan,  which shall be evidenced by a promissory note, shall be
converted  to, or  substituted  with, an  interest-bearing  loan (secured by the
first mortgage) with a thirty (30) year amortization schedule and with a rate of
interest equal to the lesser of (i) the rate then charged by Bank of America for
similar  mortgages,  or (ii) the lesser of (A) eight  percent  (8%),  or (B) the
percentage equal to the number determined by dividing the difference between the
sum of  Executive's  then  current  Base  Salary and minimum  annual  bonus less
$400,000 by $10,000 (provided that if originally (B) is the lower amount, as (B)
increases  a new  calculation  under (ii) shall be made and the rate of interest
adjusted accordingly.



                                       13
<PAGE>

                           (c)  Notwithstanding  anything else herein,  the Loan
shall  become  due and  payable in full upon the  earliest  of (i) sale or other
transfer of the residence  securing the Loan, (ii) uncured breach of the term of
the mortgage (which shall have normal  commercial  default  provisions) or (iii)
one hundred  twenty (120) days after  Executive  commenced  other  substantially
full-time  employment  or  consulting.  In addition,  the Loan shall be promptly
reduced by the after-tax  amount of the bonus referred to in Section 3(d) hereof
upon receipt by Executive of such bonus.

                           (d)  The  Loan  referred  to in (a)  above  shall  be
forgiven  in the  Specified  Amount (as defined  below),  and, to the extent the
Specified Amount exceeds the outstanding  balance of the Loan, the Company shall
pay Executive  such excess in the event (i)  Executive is still  employed at the
end of the  Original  Employment  Term,  (ii)  terminated  theretofore  for Good
Reason, or (iii) is terminated  theretofore by the Company without Cause. In the
case of (i) the Specified  Amount is the amount by which the Appraised  Value of
his residence secured by the mortgage at the end of the Original Employment Term
is less than his purchase cost of the residence (or, if the residence costs more
than $2.4 million,  the relative percentage of the 


                                       14
<PAGE>

difference based on the ratio of $2.4 million to the actual purchase price), but
in no event more than $2,000,000.  Appraisal shall be determined by an appraisal
obtained  from an appraiser  mutually  agreed upon by Executive  and the Company
(paid for by the Company) and, if they cannot agree on an appraiser, the average
appraisal obtained from three (3) appraisers  appointed by the AAA in accordance
with its procedures (paid for by the Company).

                  In the event of (ii) or (iii), the same terms shall apply, but
the Appraisals  shall occur at the time of termination  and, if those Appraisals
show a  Specified  Amount,  another  Appraisal  shall occur at the time the Loan
becomes due. If the second appraisal occurs and shows a Specified  Amount,  then
the amount due shall be based on the lesser of the two Specified Amounts. If the
first  appraisal  shows a difference,  no payment shall be made, but Interest on
the Loan thereafter shall be paid only on principal of the then remaining amount
on the Loan less the aforesaid difference (subject to the limitation).

                  In the  event  of  termination  of the  Employment  Term,  the
following provisions shall apply:

                           (A) In the event of  termination  by the  Company for
Cause,  the Loan  shall  become  due and  payable in full one (l) year after the
termination,  provided that, if such  


                                       15
<PAGE>

termination is in the Original  Employment Term, the Loan shall be converted to,
or be substituted by, an Interest (as defined herein) bearing  similarly secured
loan, with quarterly  amortization on a 30-year  amortization  basis during such
one year period.

                           (B) In the  event  of  voluntary  termination  by the
Executive other than for Good Reason or in the event of the  Executive's  death,
the Loan shall become immediately due and payable in full.

                           (C) In the event of termination  for  Disability,  by
the Company  without Cause or by the  Executive for Good Reason,  the Loan shall
become due and payable in full three (3) years after the  Termination,  provided
that, if such Termination is in the Original  Employment Term, the Loan shall be
converted to, or be substituted by, an Interest bearing  similarly secured loan,
with quarterly payments of Interest (as defined herein) only.

                  (e) During the Original  Employment  Term,  the Company  shall
reimburse  Executive's  property  taxes and  reasonable  home owner's  insurance
(building and furnishings  only) including,  without  limitation,  fire,  flood,
earthquake,  and  mudslide  coverage  for the new  residence  in the Palo  Alto,
California area (the  "Residence  Reimbursement").  The Residence


                                       16
<PAGE>

Reimbursement shall be made promptly upon presentation of invoices or notices of
the amount due. The  Residence  Reimbursement  shall not exceed  $42,000 for any
calendar  year.   Notwithstanding  the  foregoing,   in  the  event  Executive's
employment is  terminated  by the Company for Cause or by the Executive  without
Good Reason,  Executive  will promptly  refund to the Company the portion of any
Residence  Reimbursement  received  or made on  behalf  of  expenses  which  are
allocable to the period  subsequent  to the date of  termination.  The Residence
Reimbursement  (and the amounts payable under this sentence) shall be grossed up
in such  manner  than  the  economic  effect  to  Executive  is the  same as the
Residence  Reimbursement  was provided to Executive on a nontaxable  basis.  The
gross up shall be in accordance with Section 19 hereof.

                  (f)  Interest  shall  mean  the  lower  of (i) the  prevailing
commercial  mortgage  rates of Bank of America,  N.A.  for  mortgages of similar
amounts, periods and terms, and (ii) eight (8%) percent per annum.

                  7.       Child's Medical and Schooling Expenses.


                                       17
<PAGE>

                  Certain  benefits as set forth below shall be  conferred  upon
Executive  with  respect  to  Executive's  child who is  currently  in a special
program (the "Child"),  provided  Executive complies with the provisions of this
Section  7. The  Company  agrees  to pay for the  Executive  up to  $60,000  per
calendar year for COBRA coverage and supplemental medical and schooling expenses
(until  the  earlier  of the end of the  Original  Employment  Term or the Child
completing  high school)  incurred by the Child in a facility  equivalent to the
facility  in which the Child is  enrolled  as of the  Effective  Date,  provided
Executive uses his best efforts to mitigate such expenses  through any available
programs (including  governmental programs) or other medical coverage (including
available  spousal or COBRA  coverage).  The Executive  will provide the Company
with information and documentation to support such expenses  consistent with the
Company's  requirements with respect to reporting and documentation of expenses.
In addition,  the Company  shall  gross-up  for tax purposes any income  arising
pursuant to the benefits provided under this Section 7, including this sentence,
so that the economic  effect to Executive is the same as if such  benefits  were
provided  in a  non-taxable  basis.  Such gross up shall be in  accordance  with
Section 19 hereof.



                                       18
<PAGE>

                  8.       Vacation.

                  During the  Employment  Term,  Executive  shall be entitled to
four (4) weeks  paid  vacation  in each full  calendar  year  (prorated  for any
partial year) to be taken at such times as mutually  agreed by the Executive and
the Chairman of the Board or the Board.  Unused  vacation in any  calendar  year
shall be lost and not carried over from year to year.

                  9.       Termination.

                           (a) Executive's employment under this Agreement shall
terminate prior to December 31, 2001 upon the occurrence of any of the following
events:

                                (i)  Automatically  on the  date of  Executive's
death.

                                (ii) Upon  written  notice by the Company to the
Executive,  if the Executive (as determined by the Board in good faith) fails to
regularly  perform the material duties hereunder by reason of mental or physical
illness or incapacity  for an aggregate  period of more than 180 days during any
365 day period (a "Disability"), provided that, during the Employment Term prior
to such termination, the Company's obligations hereunder shall be reduced by any
payments being received by Executive under any long-term disability program.

                                (iii) Upon written  notice by the Company to the
Executive for Cause.  Cause shall mean (A) the Executive  being convicted of (or
pleading nolo  contendere to) a felony (other than a  traffic-related  offense);
(B) the barring of the Executive by any  regulatory  


                                       19
<PAGE>

authority from holding his positions or any  limitations  imposed on the Company
by any regulatory agency if the Executive  continued to hold his positions;  (C)
willful  refusal by the  Executive  to attempt to properly  perform his material
obligations  under this  Agreement,  or attempt to follow any  direction  of the
Board  consistent  with this  Agreement,  which in either  case is not  remedied
within  ten (10)  business  days  (with  appropriate  reasonable  adjustment  if
Executive  is at the time of  notice  away on  vacation)  after  receipt  by the
Executive of written  notice from the Company  specifying  the details  thereof,
provided the refusal to follow a direction  shall not be Cause if the  Executive
in good faith  believes that such  direction is not legal and promptly  notifies
the Board in writing of such belief;  (D) the Executive's  willful misconduct or
material gross  negligence  with regard to the business,  assets or employees of
the Company or its affiliated entities (including as willful misconduct, without
limitation,  the Executive's  willful breach of any fiduciary duty he may owe to
the Company or its affiliates  under applicable law or this agreement but not de
minimis  personal use of Company assets or reasonable good faith expense account
disputes),  (E) the  Executive's  theft,  dishonesty or fraud with regard to the
Company or its  affiliates  which is intended to enrich the Executive or another
person or entity but not de minimis personal use of Company assets or reasonable
good faith expense  account  disputes,  or (F) any other material  breach by the
Executive  of this  Agreement  that  remains  uncured for twenty (20) days after
written notice thereof is given to the Executive. During any period in which the
Executive is charged with  committing a crime covered by (A) above,  the Company
may suspend  Executive  from his titles,  duties and  authority  herein  pending
resolution of his status under applicable law; such suspension shall be with pay
for up to six (6) months and thereafter shall be without pay.


                                       20
<PAGE>

                                (iv)  Immediately  upon  written  notice  to the
Executive by the Company  without  Cause.  A  termination  of this  Agreement by
virtue  of  the  Company  notifying  Executive  that  the  Agreement  shall  not
automatically extend pursuant to Section 2 hereof shall constitute a termination
of Executive by the Company other than for Cause as of the end of the Employment
Term.

                                (v)  Upon  the  voluntary   termination  of  the
Executive  without Good Reason upon thirty (30) days prior written notice to the
Company (which the Company may, in its sole discretion, make effective earlier).
A notice by Executive of non-renewal  of the  Employment  Term shall be deemed a
voluntary termination by Executive.

                                (vi) Upon written  notice by the  Executive  for
Good Reason  stating with  specificity  the details of the Good  Reason,  if the
stated  Good Reason is not cured  within  twenty (20) days of the giving of such
notice. Any notice for Good Reason shall be given within ninety (90) days of the
later of (i) the occurrence of the triggering event, or (ii) the date upon which
Executive  could be  reasonably  expected to know of such event.  "Good  Reason"
shall mean (A) any material reduction in authority,  duties or  responsibilities
(except  temporarily in connection with a suspension as set forth in (iii) above
or during any period of  physical  or mental  illness);  (B) any  reduction,  in
Executive's title or level of reporting;  (C) the relocation of the Executive to
a facility or a location more than fifty (50) miles from the Executive's then


                                       21
<PAGE>

present  location,  without the Executive's  written  consent;  or (D) any other
material  breach of any  provision of this  Agreement by the Company,  including
without  limitation,  a  reduction  by the Company in the Base Salary or minimum
annual bonus of the Executive as in effect; immediately prior to such reduction.
In addition,  the Executive may terminate  employment by written notice given to
the Company within the thirty (30) day period following the first anniversary of
a Change in Control of the Company (as  currently  defined in the Plan) and have
such termination treated as a termination for Good Reason.

                           (b) Upon such earlier  termination  of the Employment
Term,  the  Executive  shall be  promptly  paid any unpaid  salary  and  accrued
vacation  through  his date of  termination,  a  prorated  portion of his unpaid
annual  minimum bonus for the calendar year of his  termination,  reimbursed for
any expenses  incurred in  connection  with the business of the Company prior to
his date of termination  which he would be otherwise  entitled to  reimbursement
for in accordance with the Company's  policies on the  reimbursement of business
expenses,  receive any  benefits or fringes due under any benefit or fringe plan
or arrangement in accordance  with the terms of said plan or arrangement due for
the period prior to such termination. In


                                       22
<PAGE>

addition,  if the  termination is pursuant to Section  9(a)(iv) or (a)(vi) above
and prior to the Executive's  sixty-fifth birthday,  the Executive shall receive
in full settlement of all amounts owed him,  provided he signs a release running
to the Company and its related entities and their respective officers, directors
and employees of all claims,  relating to his employment and termination thereof
(other  than any  right to  indemnification  under  the  Company's  Articles  of
Incorporation or By-Laws or the  Indemnification  Agreement annexed as Exhibit B
hereto,  which  shall  survive)  in such  form as  reasonably  requested  by the
Company, (i) twelve (12) monthly installments of severance pay each in an amount
equal to the  greater  of  $41,375  or  one-twelfth  of the then sum of his Base
Salary and minimum annual bonus,  subject to the offset of any amounts due under
Section  6  hereof,  and  (ii)  payment  by  the  Company  of the  premiums  for
Executive's  and  his  dependents'  COBRA  coverage  for  the  Company's  health
insurance  plan that  generally  applies to  executives  for the period in which
Executive is  receiving  severance  pursuant to (i) above or, if earlier,  until
Executive and his dependents  cease to be eligible for such COBRA  coverage.  In
addition,  in the event  Executive's  employment is terminated prior to December
31,  2000  pursuant  to Section  9(a)(iv) or  9(a)(vi),  the Company  shall pay,
provided Executive (or, in


                                       23
<PAGE>

the case of his death,  his executors)  executes the release of claim  described
above,  the special bonus in Section 3(d) hereof  (subject to the same rights of
offset as set forth  therein).  The  Company's  payment  obligations  under this
Section 9(b) (other than those in the first sentence) shall immediately cease in
the event Executive  materially  breaches any of his obligations  under Sections
12, 13 or 14 of this Agreement.

                           (c) If the  Employment  Term ends early  pursuant  to
Section  9(a)(ii)  hereof on account of Disability,  and Executive  executes the
release of claim set forth in  subsection  (b) above,  the Company  shall pay to
Executive  monthly,  until the second anniversary of the date of the termination
for Disability,  the amount of $27,750,  less any payments to which Executive is
entitled for such month under any disability benefit plan or the like sponsored,
or  contributed  to,  by the  Company  (including,  without  limitation,  Social
Security);  provided, however, that in the event of Executive's death during the
payment  period,  the Company  shall not be  obligated  to pay any such  amounts
subsequent to the date of Executive's death. In addition, in the event Executive
is terminated for Disability prior to December 31, 2000 and such Disability is a
"Total and Permanent  Disability"  within the meaning of Section 72(m)(7) of the
Internal  



                                       24
<PAGE>

Revenue Code of 1986, as amended (the "Code"), the Company shall pay (subject to
Executive's  execution of the release of claim described in subsection (b) above
and the right to offset as provided in Section 3(d)),  the special bonus payable
under Section 3(d) hereof. The Company's payment  obligations under this Section
9(c) shall immediately cease in the event Executive  materially  breaches any of
his obligations under Sections 12, 13 or 14 of this Agreement.  After the end of
such two (2) year period, Executive shall only be entitled to receive amounts as
he may be entitled to under any  disability  policy  specified  in Section  4(c)
hereof or otherwise sponsored by the Company.

                           (d) If the  Employment  Term ends early  pursuant  to
Section 9 hereof for any reason, except as expressly provided in this Section 9,
Executive  shall  cease to have any rights to salary,  bonus or  benefits  other
than:  (i) salary or bonus  which has accrued but is unpaid as of the end of the
Employment  Term,  and (ii) but only to the extent  provided  in any  benefit or
equity plan or arrangement in which Executive has participated as an employee of
the Company,  any benefits or rights which by their specific terms extend beyond
termination of Executive's employment.

                                       25
<PAGE>

                           (e) All aforesaid  amounts in this Section 9 shall be
subject to required  withholding.  The Company and its affiliated entities shall
have  no  other  obligations  to the  Executive  upon a  termination  except  as
specifically provided in this Agreement.

                  10.      Special Tax Provision.

                           (a)  Anything  in  this  Agreement  to  the  contrary
notwithstanding, in the event that any amount or benefit paid, payable, or to be
paid, or distributed,  distributable, or to be distributed to or with respect to
Executive  (whether  pursuant to the terms of this  Agreement or any other plan,
arrangement or agreement with the Company,  any person whose actions result in a
change of ownership or effective  control  covered by Section  280G(b)(2) of the
Code or any person  affiliated with the Company or such person) as a result of a
change in ownership or effective  control of the Company or a direct or indirect
parent  (within the meaning of Section 280G of the Code)  thereof (or the assets
of any of the foregoing) covered by Code Section 280G(b)(2)  (collectively,  the
"Covered  Payments") is or becomes subject to the excise tax imposed by or under
Section  4999 of the Code (or any similar tax that may  hereafter  be  imposed),
and/or any  interest or  penalties  with respect to such excise tax (such excise
tax,  


                                       26
<PAGE>

together with such interest and penalties, is hereinafter  collectively referred
to as the "Excise Tax"), the Company shall pay to Executive an additional amount
(the "Tax  Reimbursement  Payment")  such that after payment by Executive of all
taxes (including,  without limitation,  any interest or penalties and any Excise
Tax  imposed  on or  attributable  to the  Tax  Reimbursement  Payment  itself),
Executive retains an amount of the Tax Reimbursement Payment equal to the sum of
(i) the amount of the Excise Tax  imposed  upon the Covered  Payments,  and (ii)
without  duplication,  an  amount  equal to the  product  of (A) any  deductions
disallowed  for  federal,  state or local  income  tax  purposes  because of the
inclusion of the Tax Reimbursement Payment in Executive's adjusted gross income,
and (B) the highest applicable  marginal rate of federal,  state or local income
taxation,  respectively,  for the calendar  year in which the Tax  Reimbursement
Payment is made or is to be made.  The  intent of this  Section 10 is that after
Executive  pays  federal,  state and local  income  tax and any  payroll  taxes,
Executive  will be in the same position as if Executive  were not subject to the
Excise Tax under Section 4999 of the Code and did not receive the extra payments
pursuant  to  this  Section  10  and  this  Section  10  shall  be   interpreted
accordingly.

                                       27
<PAGE>

                           (b) Except as  otherwise  provided in Section  10(a),
for purposes of determining  whether any of the Covered Payments will be subject
to the Excise Tax and the amount of such Excise Tax, such Covered  Payments will
be treated as "parachute  payments" (within the meaning of Section 280G(b)(2) of
the Code) and such  payments  in excess  of the Code  Section  280G(b)(3)  "base
amount" shall be treated as subject to the Excise Tax, unless, and except to the
extent that, the Company's  independent  certified public accountants  appointed
prior to the change in  ownership  covered by Code Section  280G(b)(2)  or legal
counsel   (reasonably   acceptable  to  Executive)   appointed  by  such  public
accountants (or, if the public accountants  decline such appointment and decline
appointing such legal counsel,  such independent certified public accountants as
promptly  mutually  agreed on in good faith by the Company and  Executive)  (the
"Accountant"),  deliver a written opinion to Executive,  reasonably satisfactory
to  Executive's  legal counsel,  that, in the event such  reporting  position is
contested by the Internal Revenue Service,  there will be a more likely than not
chance of success with respect to a claim that the Covered Payments (in whole or
in  part)  do  not  constitute   "parachute   payments,"   represent  reasonable
compensation  for  services  actually  rendered  (within  the meaning of Section



                                       28
<PAGE>

280G(b)(4)  of the  Code) in  excess  of the  "base  amount"  allocable  to such
reasonable compensation,  or such "parachute payments" are otherwise not subject
to such Excise Tax (with  appropriate  legal  authority,  detailed  analysis and
explanation  provided therein by the  Accountant);  and the value of any Covered
Payments which are non-cash  benefits or deferred  payments or benefits shall be
determined by the  Accountant in accordance  with the principles of Section 280G
of the Code.

                           (c) For purposes of determining the amount of the Tax
Reimbursement  Payment,  Executive shall be deemed: to pay federal, state and/or
local income taxes at the highest  applicable  marginal rate of income  taxation
for the calendar year in which the Tax Reimbursement Payment is made or is to be
made, and to have otherwise  allowable  deductions for federal,  state and local
income tax purposes at least equal to those  disallowed  due to the inclusion of
the Tax Reimbursement Payment in Executive's adjusted gross income.

                           (d)(i)(A)  In  the  event  that  prior  to  the  time
Executive  has filed any of  Executive's  tax returns for the  calendar  year in
which the change in ownership event covered by Code Section 280G(b)(2) occurred,
the Accountant determines,  for any reason whatsoever, the 


                                       29
<PAGE>

correct  amount of the Tax  Reimbursement  Payment  to be less  than the  amount
determined at the time the Tax Reimbursement  Payment was made,  Executive shall
repay to the  Company,  at the time  that the  amount of such  reduction  in Tax
Reimbursement Payment is determined by the Accountant,  the portion of the prior
Tax Reimbursement  Payment attributable to such reduction (including the portion
of the Tax  Reimbursement  Payment  attributable  to the Excise Tax and federal,
state and local  income  tax  imposed on the  portion  of the Tax  Reimbursement
Payment  being  repaid by  Executive,  using  the  assumptions  and  methodology
utilized  to  calculate  the  Tax  Reimbursement   Payment  (unless   manifestly
erroneous)),  plus interest on the amount of such repayment at the rate provided
in Section 1274(b)(2)(B) of the Code.

                                 (B) In the  event  that the  determination  set
forth in (A) above is made by the  Accountant  after the filing by  Executive of
any of  Executive's  tax  returns for the  calendar  year in which the change in
ownership event covered by Code Section 280G(b)(2) occurred but prior to one (1)
year after the occurrence of such change in ownership,  Executive  shall file at
the  request  of the  Company  an  amended  tax  return in  accordance  with the
Accountant's  determination,  but no  portion of the Tax  Reimbursement  Payment
shall be required 


                                       30
<PAGE>

to be refunded to the Company  until actual refund or credit of such portion has
been made to Executive, and interest payable to the Company shall not exceed the
interest  received or credited to Executive by such tax authority for the period
it held such portion (less any tax Executive must pay on such interest and which
Executive is unable to deduct as a result of payment of the refund).

                                 (C) In the event  Executive  receives  a refund
pursuant  to (B) above and repays such amount to the  Company,  Executive  shall
thereafter  file for any  refunds or  credits  that may be due to  Executive  by
reason  of the  repayments  to the  Company.  Executive  and the  Company  shall
mutually agree upon the course of action,  if any, to be pursued (which shall be
at the expense of the Company) if Executive's claim for such refund or credit is
denied.

                              (ii) In the  event  that the  Excise  Tax is later
determined  by the  Accountant  or the  Internal  Revenue  Service to exceed the
amount taken into account hereunder at the time the Tax Reimbursement Payment is
made (including by reason of any payment the existence or amount of which cannot
be determined at the time of the Tax Reimbursement  Payment),  the Company shall
make an additional Tax Reimbursement Payment in respect of such excess (plus any
interest or  penalties  payable  with respect to such excess) once the amount of
such excess is finally determined.

                              (iii)  In the  event of any  controversy  with the
Internal  Revenue  Service (or other  taxing  authority)  under this Section 10,
subject to the second  sentence of 


                                       31
<PAGE>

subpart  (i)(C)  above,  Executive  shall  permit the Company to control  issues
related to this Section 10 (at its  expense),  provided  that such issues do not
potentially  materially adversely affect Executive,  but Executive shall control
any other issues.  In the event the issues are  interrelated,  Executive and the
Company  shall in good faith  cooperate so as not to  jeopardize  resolution  of
either issue,  but if the parties  cannot agree  Executive  shall make the final
determination with regard to the issues. In the event of any conference with any
taxing  authority as to the Excise Tax or  associated  income  taxes,  Executive
shall  permit the  representative  of the Company to  accompany  Executive,  and
Executive  and his  representative  shall  cooperate  with the  Company  and its
representative.

                              (iv)  With  regard  to any  initial  filing  for a
refund or any other action  required  pursuant to this Section 10 (other than by
mutual  agreement) or, if not required,  agreed to by the Company and Executive,
Executive shall  cooperate  fully with the Company,  provided that the foregoing
shall not apply to actions that are provided  herein to be at  Executive's  sole
discretion.

                           (e) The Tax  Reimbursement  Payment,  or any  portion
thereof,  payable  by the  Company  shall be paid not  later  than the fifth day
following the  determination by the Accountant,  and any payment made after such
fifth  day  shall  bear   interest  at  the  rate   provided  in  Code   Section
1274(b)(2)(B). The Company shall use its best efforts to cause the Accountant to

                                       32
<PAGE>

promptly  deliver  the  initial  determination  required  hereunder  and, if not
delivered,  within ninety (90) days after the change in ownership  event covered
by Section  280G(b)(2)  of the Code,  the Company  shall pay  Executive  the Tax
Reimbursement  Payment  set  forth in an  opinion  from  counsel  recognized  as
knowledgeable  in the  relevant  areas  selected by  Executive,  and  reasonably
acceptable to the Company,  within five (5) days after delivery of such opinion.
In  accordance  with  Section  9(e),  the  Company  may  withhold  from  the Tax
Reimbursement  Payment and  deposit  into  applicable  taxing  authorities  such
amounts as they are required to withhold by  applicable  law. To the extent that
Executive  is required to pay  estimated  or other taxes on amounts  received by
Executive  beyond any  withheld  amounts,  Executive  shall  promptly  make such
payments.  The amount of such payment  shall be subject to later  adjustment  in
accordance with the determination of the Accountant as provided herein.

                           (f) The  Company  shall  be  responsible  for (i) all
charges of the Accountant, (ii) if (e) is applicable, the reasonable charges for
the opinion given by Executive's  counsel,  and (iii) all reasonable  charges in
connection  with the preparation and filing of any amended tax returns on behalf
of the Executive requested by the Company,  required  hereunder,  


                                       33
<PAGE>

or required by applicable  law. The Company shall  gross-up for tax purposes any
income to Executive arising pursuant to this subsection (f) so that the economic
effect  to  Executive  is  the  same  as if  the  benefits  were  provided  on a
non-taxable basis. Such gross-up shall be in accordance with Section 19 hereof.

                           (g) Executive and the Company shall mutually agree on
and  promulgate  further  guidelines in  accordance  with this Section 10 to the
extent,  if any,  necessary to effect the reversal of excessive or shortfall Tax
Reimbursement  Payments. The foregoing shall not in any way be inconsistent with
Section 10(d)(i)(C) hereof.

                  11.      No Duty to Mitigate/Set-Off.

                  The  Company's  obligation  to make  payments  provided  under
Section  9 of this  Agreement,  other  than as  specifically  set  forth in this
Agreement,  shall not be  affected  by any  set-off,  counterclaim,  recoupment,
defense,  or other claim, right or action which the Company may have against the
Executive or others. The Company agrees that if Executive's  employment with the
Company  is  terminated  during  the  Employment  Term,  Executive  shall not be
required to seek other employment or to attempt in any way to reduce any amounts
payable to Executive by 


                                       34
<PAGE>

the Company  pursuant to this Agreement.  Further,  the amount of any payment or
benefit  provided for in this Agreement shall not be reduced by any compensation
earned by Executive or benefit provided to Executive as the result of employment
by another employer or otherwise. Any amounts due under Section 9 are inclusive,
and in lieu of, any amounts payable under any other salary  continuation or cash
severance  arrangement  of the Company and to the extent paid or provided  under
any other such arrangement shall be offset from the amount due under Section 9.

                  12.      Inventions and Other Intellectual Property.

                  The  Company  and  Executive  agree to  promptly  execute  the
Proprietary Information and Invention Agreement, annexed as Exhibit C hereto.

                  13.      Confidential Information.

                  Executive acknowledges that the information,  observations and
data obtained by him while  employed by the Company  pursuant to this  Agreement
concerning the business or affairs of the Company or any of its  subsidiaries or
affiliates  or any  predecessor  thereof  ("Confidential  Information")  are the
property of the Company or such subsidiary or affiliate.  


                                       35
<PAGE>

Executive  agrees that he shall not disclose to any  unauthorized  person or use
for his own  account any  Confidential  Information  without  the prior  written
consent  of the  Chairman  of the Board or the Board  unless  and  except to the
extent that the  aforementioned  matters become generally known to and available
for use by the public other than as a result of Executive's acts or omissions to
act or, while employed,  he discloses based on his good faith determination that
to do so is in the best  interests of the Company.  If Executive  receives legal
process,  he may comply with it provided  he promptly  notifies  the Company and
cooperates  with the Company in obtaining a protective  order.  Executive  shall
deliver to the Company at the  termination  of the  Employment  Term,  or at any
other time the  Company may  request,  all  memoranda,  notes,  plans,  records,
reports,  computer  tapes and software and other  documents and data (and copies
thereof)  relating  to the  Confidential  Information,  the Work  Product or the
business of the Company or any of its  subsidiaries  or affiliates  which he may
then possess or have under his control.

                  14.      Non-Compete, Non-Solicitation.

                           (a) Executive  acknowledges that in the course of his
employment  with the Company  pursuant to this Agreement he will become familiar
with trade secrets of and other 


                                       36
<PAGE>

Confidential  Information  concerning  the  Company  and  its  subsidiaries  and
affiliates  and  predecessors  thereof and that his services will be of special,
unique and extraordinary value to the Company.

                           (b) During the Employment  Term and for two (2) years
thereafter,  Executive shall not enter into  Competition with the Company or its
affiliates  to the  extent  such  Competition  requires  Executive  to  divulge,
disclose or  communicate  to any third party any Company  "trade secret" as that
term  is  defined  under   California  law.  For  purposes  of  this  Agreement,
Competition shall mean participating,  directly or indirectly,  as an individual
proprietor,  partner, stockholder,  officer, employee, director, joint venturer,
investor,  lender,  consultant or in any capacity  whatsoever (within the United
States  or in any  foreign  country  where  the  Company  or its  affiliates  do
business)  in a business  in  competition  with any  business  conducted  by the
Company or its affiliates with regard to which Executive worked or otherwise had
responsibilities  or had  access  to  material  Confidential  Information  while
employed  by the  Company  or  its  affiliates;  provided,  however,  that  such
participation  shall not  include  (i) the mere  ownership  of not more than two
percent (2%) of the total outstanding stock of a publicly 


                                       37
<PAGE>

held company,  (ii) the performance of services for any enterprise to the extent
such services are not performed,  directly or indirectly,  for a business in the
aforesaid  competition,  (iii) any  activity  engaged in with the prior  written
approval of the Chairman of the Board, or (iv)  Executive's  employment by a non
Competitive  division  (or  other  business  unit)  of a  company  which  is  in
Competition  with the  Company so long as  Executive  is not  involved  with the
competitive division (or other business unit).  Notwithstanding anything else in
this Section 14(b) to the contrary, subsequent to the termination of Executive's
employment hereunder, Executive may, in his sole discretion, passively invest in
any entity,  provided  Executive does not divulge,  disclose or communicate  any
Company  "trade  secrets" or  Confidential  Information  to such  company or its
affiliates,  employees, officers, consultants,  directors, lenders, or investors
and further  provided  Executive  does not render  services  to such  company in
violation of this Section 14 or otherwise  violates  this Section 14 (other than
by making such passive investments).

                           (c) During the Employment  Term and for two (2) years
thereafter,  Executive shall not directly or indirectly  solicit for Competitive
products or induce any customer of the Company or its  affiliates  to terminate,
or otherwise to cease,  reduce, or diminish in any 



                                       38
<PAGE>

way its relationship with the Company or its affiliates.

                           (d) During the  Employment  Term and the one (1) year
thereafter,  Executive  shall not  recruit,  solicit or induce  any  nonclerical
employees of the Company or its affiliates to terminate their  employment  with,
or otherwise  cease their  relationship  with,  the Company or its affiliates or
hire or assist another person or entity to hire any nonclerical  employee of the
Company or its  affiliates  or any  person who within six (6) months  before had
been  a  nonclerical   employee  of  the  Company  or  any  of  its  affiliates.
Notwithstanding  the foregoing,  if requested by any entity with which Executive
is not affiliated,  Executive may serve as a reference for any person who at the
time of the request is not an employee of the Company or any of its affiliates.

                           (e) If, at the time of  enforcement  of this  Section
14, a court holds that the  restrictions  stated herein are  unreasonable  under
circumstances  then existing,  the parties hereto agree that the maximum period,
scope  or  geographical  area  reasonable  under  such  circumstances  shall  be
substituted  for the stated  period,  scope or area and that the court  shall be
allowed to revise the restrictions contained herein to cover the maximum period,
scope and area 



                                       39

permitted by law.

                  15.      Enforcement.

                  Because Executive's  services are unique and because Executive
has  access to  Confidential  Information  and  intellectual  properties  of the
Company and its affiliates, the parties hereto agree that money damages would be
an inadequate remedy for any breach of this Agreement. Therefore, in the event a
breach or threatened breach of this Agreement,  the Company or its successors or
assigns may, in addition to other  rights and remedies  existing in their favor,
apply to any court of competent  jurisdiction  for specific  performance  and/or
injunctive or other relief in order to enforce,  or prevent any  violations  of,
the provisions hereof (without posting a bond or other security).

                  16.      Indemnification.

                  Executive   shall  be  entitled  to  be  indemnified  for  his
activities as an officer or director to the full extent provided in the Articles
of  Incorporation  and  By-Laws  of the  Company  and  in  accordance  with  the
Indemnification  Agreement  annexed as Exhibit B hereto,  which the  Company and
Executive  agree to promptly  execute.  In  addition,  the  Company  shall cover

                                       40
<PAGE>

Executive under Directors and Officers Liability  Insurance both during and, for
six (6) years  after,  the  Employment  Term in the same  amount and to the same
extent as the Company covers its other officers and directors.

                  17.      Executive Representations.

                  Executive  represents and warrants to the Company that (i) the
execution,  delivery and performance of this Agreement by Executive does not and
will not conflict with,  breach,  violate or cause a default under any contract,
agreement,  instrument,  order, judgment or decree to which Executive is a party
or by which he is bound,  (ii) except with respect to agreements which have been
furnished to the Company and relate primarily to  confidentiality,  intellectual
properties  and/or  ethical  conduct  entered into between  Executive and IBM or
between  Executive and other entities in the course of his employment  with IBM,
Executive  is not a party to or bound by any  employment  agreement,  change  in
control agreement,  non-compete agreement or confidentiality  agreement with any
other person or entity,  (iii) upon the execution and delivery of this Agreement
by the Company,  this  Agreement  shall be the valid and binding  obligation  of
Executive,  enforceable in accordance with its terms, (iv) Executive is a United
States  citizen or a 


                                       41
<PAGE>

resident  alien  thereof  entitled to work therein,  and (v)  Executive  will in
performing  his duties not utilize  any  confidential  information  of any other
person or entity.

                  18.      Entire Agreement; Modification.

                  This Agreement constitutes the full and complete understanding
of  the  parties   hereto  and  will   supersede   all  prior   agreements   and
understandings, oral or written, with respect to the subject matter hereof. Each
party  to this  Agreement  acknowledges  that no  representations,  inducements,
promises or agreements,  oral or otherwise,  have been made by either party,  or
anyone acting on behalf of either party,  which are not embodied herein and that
no other  agreement,  statement or promise not contained in this Agreement shall
be valid or binding.  This Agreement may not be modified or amended except by an
instrument in writing signed by the party against whom or which  enforcement may
be sought.

                  19.      Gross Ups.

                  All gross ups  hereunder  shall be  determined by agreement of
the Company's,  and  Executive's  accountants.  The Executive  shall provide the
Company's  accountants with such information as they reasonably request in order
to  make  the  necessary  determination  as to  


                                       42
<PAGE>

Executive's tax rates and the deductibility of various items. In calculating the
gross up, the  Company's  gross up items when combined  with  Executive's  other
deductions  shall  receive the most favored  treatment and the Company shall get
the  full  benefits  of  any  deductions  available.  If  Executive  voluntarily
terminates  employment without Good Reason or is terminated with Cause, any lost
tax deduction on any gross up item shall be treated as if such  termination  did
not occur. Gross ups shall be paid as soon as reasonably  possible after payment
of the  respective  item  (and  shall  generally  be  withheld  and  paid to the
applicable taxing authorities), subject to adjustment at year end (including, if
applicable, repayment).

                  20.      Survival.

                  The  provisions of this  agreement  which by their terms imply
continuation beyond the end of the Employment Term shall survive notwithstanding
any termination of the Employment Term.

                  21.      Severability.

                  Any term or  provision of this  Agreement  which is invalid or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such invalidity or  


                                       43
<PAGE>

unenforceability  without rendering invalid or unenforceable the remaining terms
and provisions of this Agreement or affecting the validity or  enforceability of
any of the terms of provisions of this Agreement in any other jurisdiction.

                  22.      Waiver of Breach.

                  The waiver by any party of a breach of any  provisions of this
Agreement, which waiver must be in writing to be effective, shall not operate as
or be construed as a waiver of any subsequent breach.

                  23.      Notices.

                  All notices  hereunder shall be in writing and shall be deemed
to have been duly given when  delivered by hand, or one (1) day after sending by
express mail or other  "overnight mail service," or three (3) days after sending

                  24.      Assignability; Binding Effect.

                  This Agreement  shall be binding upon and inure to the benefit
of Executive and Executive's legal representatives,  heirs and distributees, and
shall be binding  upon and inure to the benefit of the Company,  its  successors
and assigns. This Agreement may not be assigned by the Executive. This Agreement
may not be assigned by the Company, except in connection with a merger or a sale
by the Company of all or substantially  all of its assets and then only provided
the assignee  specifically  assumes in writing all of the Company's  obligations
hereunder.

                  25.      Legal Fee Reimbursement.

                  The Company agrees to pay  Executive's  reasonable  legal fees
associated with entering into this Agreement up to $10,000 upon  presentation of

                 This Agreement may be executed in several  counterparts,  each
of which  shall be  deemed to be an  original  but all of which  together  shall
constitute one and the same instrument.

                  IN WITNESS  WHEREOF,  the Company has caused this Agreement to
be duly  executed and  Executive  has hereunto set his hand as of the date first

                                    EXHIBIT A

                               CYLINK CORPORATION

                       NONQUALIFIED STOCK OPTION AGREEMENT


                  This Agreement is made as of November 6, 1996,  between CYLINK
CORPORATION,  a  California  corporation  (the  "Company"),  and Fernand  Sarrat
("Optionee").

                                   WITNESSETH:

                  WHEREAS,  the  Company has  adopted  its 1994  Flexible  Stock
Incentive  Plan (the "Plan"),  which Plan is  incorporated  in this Agreement by
reference and made a part of it; and

                  WHEREAS,  the Company regards Optionee as a valuable  employee
of or service  provider to the Company,  and has determined  that it would be to
the advantage and in the interests of the Company and its  shareholders to grant
the options  provided  for in this  Agreement  to Optionee as an  inducement  to
remain in the employ or service of the Company and as an incentive for increased
efforts during such employment or service;

                  NOW,  THEREFORE,  in  consideration  of the  mutual  covenants
hereinafter set forth, the parties to this Agreement hereby agree as follows:

                  1. Option  Grant.  The Company  hereby  grants to Optionee the
right and  option  to  purchase  from the  Company  on the terms and  conditions
hereinafter  set forth,  all or any part of an aggregate of 1,000,000  shares of
the Company's  Common Stock,  $0.01 par value (the "Stock").  This option is not
intended to satisfy the requirements of Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code") and qualify as an incentive  stock option.  All
of the terms and  conditions  of this  Option  Grant are  subject to  Optionee's
Employment Agreement dated November 6, 1996 (the "Employment Agreement"), and in
the event of any  conflict  between  Optionee's  Employment  Agreement  and this
Option Grant, the terms of the Employment Agreement shall prevail.

                  2. Option  Price.  The per share  purchase  price of the Stock
subject to this option shall be $11.00, which price is not less than one hundred
percent  (100%) of the per share fair market value of such Stock as of the Grant
Date (defined below) as determined by the Board of Directors of the Company or a
Committee designated by it (the "Committee"). The term "Option Price" as used in
this  agreement  refers to the per share  purchase price of the Stock subject to
this option.


                                       1
<PAGE>

                  3. Option Period. This option shall be exercisable only during
the Option Period,  and during such Option  Period,  the  exercisability  of the
option  shall be subject  to the  limitations  of  paragraph  4 and the  vesting
provisions of paragraph 5. The Option Period shall  commence on November 6, 1996
(the "Grant  Date") and except as provided in paragraph 4, shall  terminate  ten
(10) years from the Grant Date (the "Termination Date").

                  4. Limits on Option  Period.  The Option Period may end before
the Termination Date, as follows:

                           (a) If Optionee  ceases to be a bona fide employee of
or service  provider to the Company or an Affiliate (as defined in the Plan) for
any reason other than  disability  (within the meaning of  subparagraph  (c)) or
death during the Option Period,  unless  otherwise  determined by the Committee,
(i) the Option  Period shall  terminate  three (3) months after the date of such
cessation of employment or service or on the Termination  Date,  whichever shall
first  occur,  and  (ii) the  option  shall be  exercisable  only to the  extent
exercisable under paragraph 5 on the date of Optionee's  cessation of employment
or service and shall thereafter cease to be exercisable.

                           (b)  If  Optionee  dies  while  in the  employ  of or
service to the  Company or an  Affiliate,  unless  otherwise  determined  by the
Committee,  (i) the Option Period shall end one (1) year after the date of death
or on the Termination  Date,  whichever  shall first occur,  and (ii) Optionee's
executor or  administrator  or the person or persons to whom  Optionee's  rights
under this option  shall pass by will or by the  applicable  laws of descent and
distribution  may  exercise  this  option only to the extent  exercisable  under
paragraph 5 on the date of Optionee's death.

                           (c) If Optionee's employment or service is terminated
by reason of medically determinable  disability,  unless otherwise determined by
the  Committee,  (i) the Option  Period shall end one (1) year after the date of
Optionee's  cessation  of  employment  or  service or on the  Termination  Date,
whichever  shall first occur,  and (ii) the option shall be exercisable  only to
the extent exercisable under paragraph 5 on the date of Optionee's  cessation of
employment or service.

                           (d) If  Optionee  is on a leave of  absence  from the
Company or an Affiliate because of Optionee's disability,  or for the purpose of
serving the government of the country in which the principal place of employment
of Optionee is located,  either in a military or civilian capacity,  or for such
other  purpose or reason as the  Committee  may approve,  Optionee  shall not be
deemed during the period of such absence,  by virtue of such absence  alone,  to
have terminated employment or service with the Company or an Affiliate except as
the Committee may otherwise expressly provide.

                  5. Vesting of Right to Exercise Options.  Subject to the terms
of the Employment  Agreement,  and any limitations  contained in this Agreement,
the Optionee shall 


                                       2
<PAGE>

have the right to exercise  the options  granted  hereunder  as to 1.666% of the
number  of shares  of Stock  covered  by the  option  per  month for each  month
following the Grant Date, such that the option shall be fully  exercisable  five
(5) years after the Grant Date. Provided,  however,  that the Optionee shall not
have the right to exercise any options unless and until the Optionee  remains in
the  Company's  employment  for a period of one year from the date the  Optionee
commences his employment by the Company.

                           (a) Any portion of the option  that is not  exercised
shall accumulate and may be exercised at any time during the Option Period prior
to the Termination Date. No partial exercise of this option may be for less than
five percent (5%) of the total  number of shares of Stock then  available  under
this  option.  In no event shall the  Company be  required  to issue  fractional
shares.

                  6. Method of Exercise.  Optionee may exercise this option with
respect to all or any part of the shares of Stock then subject to such  exercise
as follows:

                           (a) By  giving  the  Company  written  notice of such
exercise,  specifying the number of such shares of Stock as to which this option
is exercised.  Such notice shall be accompanied by an amount equal to the Option
Price of such shares,  in the form of any one or  combination  of the following:
cash, a certified  check,  bank draft,  postal or express money order payable to
the order of the Company in lawful money of the United States. The Committee, at
its sole  discretion,  may also  permit  Optionee  to pay the Option  Price with
shares of Stock valued at fair market value,  a promissory  note of the Optionee
or in any  combination of the foregoing.  The shares of Stock shall be valued in
accordance  with  procedures  established  by the  Committee.  Any note  used to
exercise  this  option  shall be a full  recourse,  interest-bearing  obligation
containing such terms as the Committee shall determine.  If a promissory note is
used, the Optionee agrees to execute such further documents as the Committee may
deem necessary or appropriate in connection with issuing the note,  perfecting a
security interest in the Stock purchased with the note, and any related terms or
conditions that the Committee may propose.  Such further  documents may include,
not by way of limitation,  a security agreement,  an escrow agreement,  a voting
trust agreement and an assignment  separate from certificate.  In the event that
the exercise  price is satisfied by the Committee  retaining  from the shares of
Stock otherwise to be issued to Optionee shares of Stock having a value equal to
the exercise price, the Committee may issue Optionee an additional option,  with
terms  identical  to this  option  agreement,  entitling  Optionee  to  purchase
additional  Stock  in an  amount  equal  to the  number  of  shares  of Stock so
retained.

                           (b)  Optionee  shall  be  required,  as  a  condition
precedent to acquiring Stock through  exercise of the option,  to execute one or
more  agreements  relating to  obligations  in connection  with ownership of the
Stock or  restrictions  on  transfer of the Stock no less  restrictive  than the
obligations and restrictions to which the other  shareholders of the Company are
subject at the time of such exercise.

                           (c) If required by the Committee, Optionee shall give
the Company satisfactory assurance in writing,  signed by Optionee or Optionee's
legal  representative,  as the 


                                       3
<PAGE>

case may be, that such shares are being  purchased for investment and not with a
view to the distribution thereof;  provided,  however, that such assurance shall
be deemed  inapplicable  to (1) any sale of such shares by such Optionee made in
accordance with the terms of a registration  statement covering such sale, which
may hereafter be filed and become effective under the Securities Act of 1933, as
amended  (the  "Securities  Act"),  and with  respect  to  which  no stop  order
suspending the effectiveness  thereof has been issued, and (2) any other sale of
such  shares with  respect to which in the  opinion of counsel for the  Company,
such  assurance  is not  required  to be  given  in  order  to  comply  with the
provisions of the Securities Act.

                  As soon as practicable after receipt of the notice required in
paragraph 6(a) and  satisfaction  of the conditions set forth in paragraphs 6(b)
and 6(c),  the Company  shall,  without  transfer or issue tax and without other
incidental  expense  to  Optionee,  deliver  to  Optionee  at the  office of the
Company,  at 910 Hermosa Court,  Sunnyvale,  California 94086,  attention of the
Secretary,  or such other place as may be mutually acceptable to the Company and
Optionee,  a  certificate  or  certificates  of such shares of Stock;  provided,
however, that the time of such delivery may be postponed by the Company for such
period as may be  required  for it with  reasonable  diligence  to  comply  with
applicable  registration  requirements  under the Securities Act, the Securities
Exchange Act of 1934, as amended,  any applicable  listing  requirements  of any
national  securities exchange or the Nasdaq Stock Market, and requirements under
any other law or  regulation  applicable  to the  issuance  or  transfer of such
shares.

                  7.       Corporate Transactions.

                           (a) If there should be any change in a class of Stock
subject  to  this  option,   through  merger,   consolidation,   reorganization,
recapitalization, reincorporation, stock split, stock dividend (in excess of two
percent  (2%)) or other change in the  corporate  structure of the Company,  the
Company  may make  appropriate  adjustments  in order  to  preserve,  but not to
increase,  the  benefits to  Optionee,  including  adjustments  in the number of
shares of such Stock subject to this option and in the per share  purchase price
thereof.  Any adjustment made pursuant to this paragraph 7 as a consequence of a
change in the corporate  structure of the Company shall not entitle  Optionee to
acquire a number of shares of such  Stock of the  Company  or shares of stock of
any successor  company  greater than the number of shares Optionee would receive
if, prior to such change,  Optionee had actually held a number of shares of such
Stock equal to the number of shares subject to this option.

                           (b) For  purposes of this  paragraph  7, a "Corporate
Transaction"   shall   include   any  of  the   following   shareholder-approved
transactions to which the Company is a party:

                                       (i) a merger  or  consolidation  in which
         the Company is not the surviving  entity,  except for a transaction the
         principal  purpose  of which is to change  the  state of the  Company's
         incorporation;

                                       (ii)   the   sale,   transfer   or  other
         disposition of all or substantially all of the assets of the Company in
         liquidation or dissolution of the Company; or

                                       4
<PAGE>

                                       (iii)  any  reverse  merger  in which the
         Company is the surviving entity but in which securities possessing more
         than fifty  percent  (50%) of the total  combined  voting  power of the
         Company's outstanding securities are transferred to a holder or holders
         different from those who held such securities immediately prior to such
         merger.

                            (c) In the event of any Corporate Transaction,  this
option shall  terminate as of the closing of the  Corporate  Transaction  to the
extent unexercised;  provided,  however,  that notwithstanding the terms of this
option, the surviving or acquiring  corporation or its parent company may assume
the outstanding option, or issue in place hereof options providing substantially
equal value and having substantially equivalent provisions as this option.

                  8.  Limitations  on  Transfer.   This  option  shall,   during
Optionee's  lifetime,  be exercisable only by Optionee,  and neither this option
nor any right hereunder shall be transferable by Optionee by operation of law or
otherwise  other than by will or the laws of descent  and  distribution.  In the
event of any attempt by Optionee to alienate,  assign, pledge,  hypothecate,  or
otherwise  dispose of this option or of any right hereunder,  except as provided
for in this Agreement, or in the event of the levy of any attachment, execution,
or similar process upon the rights or interest hereby conferred,  the Company at
its  election  may  terminate  this option by notice to Optionee and this option
shall thereupon become null and void.

                  9. No  Shareholder  Rights.  Neither  Optionee  nor any person
entitled to exercise  Optionee's rights in the event of his death shall have any
of the rights of a  shareholder  with respect to the shares of Stock  subject to
this option  except to the extent the  certificates  for such shares  shall have
been issued upon the exercise of this option.

                           INDEMNIFICATION AGREEMENT

     THIS AGREEMENT is entered into,  effective as of 11/6,  1996 by and between
CYLINK CORPORATION,  California corporation (the "Company"),  and Fernand Sarrat
("Indemnitee").

     WHEREAS,  it is essential to the Company to retain and attract as directors
and officers the most capable person available;

     WHEREAS, Indemnitee is a director and/or officer of the Company;

     WHEREAS,  both the Company and  Indemnitee  recognize the increased risk of
litigation  and other claims  currently  being  asserted  against  directors and
officers of corporations; and

     WHEREAS,  in recognition of Indemnitee's  need for  substantial  protection
against  personal  liability  in order to  enhance  Indemnitee's  continued  and
effective  service to the Company,  and in order to induce Indemnitee to provide
services  to the Company as a director  and/or  officer,  the Company  wishes to
provide  in this  Agreement  for the  indemnification  of and the  advancing  of
expenses to  Indemnitee  to the fullest  extent  (whether  partial or  complete)
permitted  by  California  law and as set forth in this  Agreement,  and, to the
extent  insurance  is  maintained,  for the  coverage  of  Indemnitee  under the
Company's directors' and officers' liability insurance policies.

     NOW, THEREFORE,  in consideration of the above premises and of Indemnitee's
continuing  to serve the  Company  directly  or, at its  request,  with  another
enterprise,  and  intending to be legally  bound  hereby,  the parties  agree as
follows:

     1. Certain Definitions:

        (a) Board: the Board of Directors of the Company.

        (b)  Change in  Control:  shall be deemed  to have  occurred  if (i) any
"person"  (as such term is used in  Sections  13(d) and 14(d) of the  Securities
Exchange  Act of 1934,  as amended (the  "Act")),  other than a trustee or other
fiduciary holding  securities under an employee benefit plan of the Company or a
corporation  owned directly or indirectly by the  shareholders of the Company in
substantially the same proportions as their ownership of stock of


<PAGE>

the  Company,  is or becomes  the  "Beneficial  Owner" (as defined in Rule 13d-3
under  the  Act),   directly  or  indirectly,   of  securities  of  the  Company
representing 30% or more of the total voting power  represented by the Company's
then outstanding Voting Securities, or (ii) during any period of two consecutive
years,  individuals who at the beginning of such period constitute the Board and
any new director  whose  election by the Board or nomination for election by the
Company's  shareholders  was approved by a vote of at least  two-thirds (2/3) of
the directors then still in office who either were directors at the beginning of
the period or whose  election or  nomination  for  election  was  previously  so
approved,  cease for any reason to  constitute  a majority of the Board,  or, or
(iii) the  shareholders of the Company approve a merger or  consolidation of the
Company with any other  corporation,  other than a merger or consolidation  that
would result in the Voting  Securities  of the Company  outstanding  immediately
prior thereto  continuing to represent  (either by remaining  outstanding  or by
being converted into Voting  Securities of the surviving entity) at least 80% of
the total voting power  represented  by the Voting  Securities of the Company or
such   surviving   entity   outstanding   immediately   after  such   merger  or
consolidation,  or  (iv)  the  shareholders  of the  Company  approve  a plan of
complete  liquidation of the Company or an agreement for the sale or disposition
by the  Company  (in one  transaction  or a  series  of  transaction)  of all or
substantially all of the Company's assets.

        (c) Expenses:  any expense,  liability,  or loss,  including  attorneys'
fees, judgments, fines, ERISA excise taxes and penalties,  amounts paid or to be
paid in settlement, any interest, assessments, or other charges imposed thereon,
and any  federal,  state,  local,  or foreign  taxes  imposed as a result of the
accrual or deemed receipt of any payments under this Agreement, paid or incurred
in  connection   with   investigating,   defending,   being  a  witness  in,  or
participating  in (including  on appeal),  or preparing for any of the foregoing
in, any Proceeding relating to any Indemnifiable Event.

        (d) Indemnifiable Event: any event or occurrence that takes place either
prior to or after the  execution  of this  Agreement,  related  to the fact that
Indemnitee  is or was a  director  or an  officer  of the  Company,  or  while a
director  or  officer  is or was  serving  at the  request  of the  Company as a
director,  officer, employee, trustee, agent, or fiduciary of another foreign or
domestic corporation,  partnership, joint venture, employee benefit plan, trust,
or other enterprise, or was a director, officer, employee, or agent of a foreign
or domestic corporation that was a predecessor  corporation of the Company or of
another enterprise at the request of such predecessor corporation, or related to
anything done or not done by Indemnitee in any such capacity, whether or not the
basis of the Proceeding is alleged action in an official capacity as a director,
officer,  employee,  or  agent  or in any  other  capacity  while  serving  as a
director, officer, employee, or agent of the Company, as described above.

        (e) Independent Counsel: the person or body appointed in connection with
Section 3.

        (f) Potential Change in Control: shall be deemed to have occurred if (i)
the Company enters into an agreement or arrangement,  the  consummation of which
would


<PAGE>

result in the occurrence of a Change in Control;  (ii) any person (including the
Company) publicly  announces an intention to take or to consider  taking actions
that, if  consummated,  would  constitute a Change in Control;  (iii) any person
(other than a trustee or other fiduciary  holding  securities  under an employee
benefit  plan of the Company  acting in such  capacity or a  corporation  owned,
directly or indirectly,  by the shareholders of the Company in substantially the
same proportions as their ownership of stock of the Company),  who is or becomes
the  Beneficial  Owner,  directly or  indirectly,  of  securities of the Company
representing  10% or more of the  combined  voting power of the  Company's  then
outstanding  Voting  Securities,  increases  his  beneficial  ownership  of such
securities by 5% or more over the percentage so owned by such person on the date
hereof,  or (iv) the Board adopts a resolution to the effect that,  for purposes
of this Agreement, a Potential Change in Control has occurred.

        (g) Proceeding: (i) any threatened,  pending, or completed action, suit,
or proceeding,  or whether civil, criminal,  administrative,  investigative,  or
other; (ii) any inquiry,  hearing,  or  investigation,  whether conducted by the
Company or any other party, that Indemnitee in good faith believes might lead to
the institution of any such action, suit, or proceeding.

        (h) Reviewing  Party:  the person or body  appointed in accordance  with
Section 3.

        (i) Voting Securities: any securities of the Company that vote generally
in the election of directors.

     2. Agreement to Indemnify:

        (a) General  Agreement.  In the event  Indemnitee  was, is, or becomes a
party to or witness or other participant in, or is threatened to be made a party
to or witness or other  participant in, a Proceeding by reason of (or arising in
part out of) an Indemnifiable Event, the Company shall indemnify Indemnitee from
and against any and all Expenses to the fullest extent  permitted by law, as the
same exists or may hereafter be amended or  interpreted  (but in the case of any
such  amendment  or  interpretation,  only to the extent that such  amendment or
interpretation  permits the Company to provide  broader  indemnification  rights
than  were  permitted  prior  thereto).  The  parties  hereto  intend  that this
Agreement  shall  provide  for  indemnification  in  excess  of  that  expressly
permitted  by  statute,  including,   without  limitation,  any  indemnification
provided by the Company's  Articles of  Incorporation,  its bylaws,  vote of its
shareholders or disinterested directors, or applicable law.

        (b) Initiation of Proceeding. Notwithstanding anything in this Agreement
to the contrary, Indemnitee shall not be entitled to indemnification pursuant to
this Agreement in connection with any Proceeding initiated by Indemnitee against
the Company or any director or officer of the Company unless (i) the Company has
joined in or the Board has consented to the initiation of such Proceeding;  (ii)
the Proceeding is one to enforce
<PAGE>

indemnification  rights under Section 5; or (iii) the  Proceeding  is instituted
after a Change in Control and Independent Counsel has approved its initiation.

        (c) Expense Advances.  If so requested by Indemnitee,  the Company shall
advance  (within ten  business  days of such  request)  any and all  Expenses to
Indemnitee (an "Expense Advance");  provided that, if and to the extent that the
Reviewing  Party  determines  that  Indemnitee  would not be  permitted to be so
indemnified under applicable law, the Company shall be entitled to be reimbursed
by Indemnitee  (who hereby agrees to reimburse the Company) for all such amounts
theretofore  paid. If Indemnitee has commenced  legal  proceedings in a court of
competent  jurisdiction  to secure a  determination  that  Indemnitee  should be
indemnified  under  applicable law, as provided in Section 4, any  determination
made by the  Reviewing  Party  that  Indemnitee  would  not be  permitted  to be
indemnified  under  applicable law shall not be binding and Indemnitee shall not
be required to  reimburse  the  Company  for any Expense  Advance  until a final
judicial  determination  is made with respect thereto (as to which all rights of
appeal therefrom have been exhausted or have lapsed). Indemnitee's obligation to
reimburse  the Company for Expense  Advances  shall be unsecured and no interest
shall be charged thereon.

        (d) Mandatory  Indemnification.  Notwithstanding  any other provision of
this Agreement  (other than Section 2(f) below),  to the extent that  Indemnitee
has been successful on the merits in defense of any Proceeding relating in whole
or in part to an  Indemnifiable  Event or in  defense  of any  issue  or  matter
therein,  Indemnitee  shall be  indemnified  against  all  Expenses  incurred in
connection therewith.

        (e)  Partial  Indemnification.  If  Indemnitee  is  entitled  under  any
provision  of this  Agreement  to  indemnification  by the Company for some or a
portion of Expenses, but not, however, for the total amount thereof, the Company
shall  nevertheless  indemnify  Indemnitee  for the  portion  thereof  to  which
Indemnitee is entitled.

        (f)  Prohibited  Indemnification.  No  indemnification  pursuant to this
Agreement  shall be paid by the  Company on account of any  Proceeding  in which
judgment is rendered  against  Indemnitee for an accounting of profits made from
the purchase or sale by Indemnitee of securities of the Company  pursuant to the
provisions  of Section  16(b) of the Act or similar  provisions  of any federal,
state, or local laws.

     3. Reviewing  Party.  Prior to any Change in Control,  the Reviewing  Party
shall be any appropriate person or body consisting of a member or members of the
Board or any other  person or body  appointed by the Board who is not a party to
the  particular   Proceeding  with  respect  to  which   Indemnitee  is  seeking
indemnification:  after a Change in Control,  the  Reviewing  Party shall be the
Independent Counsel referred to below. With respect to all matters arising after
a Change in Control  (other  than a Change in Control  approved by a majority of
the directors on the Board who were directors  immediately  prior to such Change
in Control)  concerning  the rights of  Indemnitee  to  indemnity  payments  and
Expense Advances under this Agreement or any other agreement or under applicable
law or the Company's Articles of


<PAGE>


Incorporation  or Bylaws now or hereafter in effect relating to  indemnification
for  Indemnifiable  Events,  the  Company  shall  seek  legal  advice  only from
independent  Counsel  selected by Indemnitee  and approved by the Company (which
approval  shall  not be  unreasonably  withheld),  and  who  has  not  otherwise
performed  services for the Company or the Indemnitee  (other than in connection
with  indemnification  matters)  within  the last five  years.  The  Independent
Counsel  shall not include any person who,  under the  applicable  standards  of
professional  conduct  then  prevailing,  would have a conflict  of  interest in
representing  either  the  Company  or  Indemnitee  in an  action  to  determine
Indemnitee's  rights under this  Agreement.  Such  counsel,  among other things,
shall render its written opinion to the Company and Indemnitee as to whether and
to what  extent the  Indemnitee  should be  permitted  to be  indemnified  under
applicable law. The Company agrees to pay the reasonable fees of the Independent
Counsel  and to  indemnify  fully  such  counsel  against  any and all  expenses
(including attorneys' fees), claims, liabilities,  loss, and damages arising out
of or  relating to this  Agreement  or the  engagement  of  Independent  Counsel
pursuant hereto.

     4. Indemnification Process and Appeal.

        (a)   Indemnification   Payment.   Indemnitee   shall  be   entitled  to
indemnification of Expenses, and shall receive payment thereof, from the Company
in accordance  with this Agreement as soon as practicable  after  Indemnitee has
made written  demand on the Company for  indemnification,  unless the  Reviewing
Party has given a written opinion to the Company that Indemnitee is not entitled
to indemnification under applicable law.

        (b) Suit to Enforce  Right.  Regardless  of any action by the  Reviewing
Party,  if Indemnitee has not received full  indemnification  within thirty days
after making a demand in accordance with Section 4(a). Indemnitee shall have the
right to enforce its  indemnification  rights under this Agreement by commencing
litigation  in any  court  in the  State of  California  having  subject  matter
jurisdiction   thereof  and  in  which  venue  is  proper   seeking  an  initial
determination  by the court or challenging  any  determination  by the Reviewing
Party or any aspect  thereof.  The Company hereby consents to service of process
and to appear in any such proceeding.  Any  determination by the Reviewing Party
not challenged by the Indemnitee shall be binding on the Company and Indemnitee.
The remedy  provided  for in this  Section 4 shall be in  addition  to any other
remedies available to Indemnitee in law or equity.

        (c)  Defense to  Indemnification, Burden of Proof and  Presumptions.  It
shall be a defense to any action  brought by  Indemnitee  against the Company to
enforce  this  Agreement  (other  than an action  brought to enforce a claim for
Expenses  incurred in defending a Proceeding in advance of its final disposition
where the required  undertaking has been tendered to the Company) that it is not
permissible under applicable law for the Company to indemnify Indemnitee for the
amount claimed.  In connection with any such action or any  determination by the
Reviewing  Party  or  otherwise  as to  whether  Indemnitee  is  entitled  to be
indemnified  hereunder,  the burden of proving  such a defense or  determination
shall be on the  Company.  Neither  the  failure of the  Reviewing  Party or the
Company (including its Board, independent


<PAGE>

legal counsel,  or its  shareholders) to have made a determination  prior to the
commencement of such action by Indemnitee that  indemnification  of the claimant
is proper under the  circumstances  because  Indemnitee  has met the standard of
conduct  set  forth  in  applicable  law,  nor an  actual  determination  by the
Reviewing Party or Company (including its Board,  independent legal counsel,  or
its  shareholders)  that the Indemnitee had not met such applicable  standard of
conduct,  shall be a defense  to the  action or  create a  presumption  that the
Indemnitee has not met the applicable standard of conduct.  For purposes of this
Agreement,  the  termination  of any claim,  action,  suit,  or  proceeding,  by
judgment,   order,   settlement   (whether  with  or  without  court  approval),
conviction,  or upon a plea of nolo  contendere,  or its  equivalent,  shall not
create a presumption  that  Indemnitee did not meet any  particular  standard of
conduct  or have any  particular  belief  or that a court  has  determined  that
indemnification is not permitted by applicable law.

     5.  Indemnification  for Expenses Incurred in Enforcing Rights. The Company
shall  indemnify  Indemnitee  against any and all Expenses  and, if requested by
Indemnitee,  shall  (within ten  business  days of such  request),  advance such
Expenses to Indemnitee,  that are incurred by Indemnitee in connection  with any
claim asserted against or action brought by Indemnitee for

        (i) Indemnification of Expenses or Expense Advances by the Company under
this Agreement or any other  agreement or under  applicable law or the Company's
Articles  of  Incorporation  or Bylaws now or  hereafter  in effect  relating to
indemnification for Indemnifiable Events, and/or

        (ii)  recovery  under  directors'  and  officers'   liability  insurance
policies maintained by the Company.

regardless of whether Indemnitee ultimately is determined to be entitled to such
indemnification. Expense Advances, or insurance recovery, as the case may be.

     6. Notification and Defense of Proceeding.

        (a)  Notice.  Promptly  after  receipt  by  Indemnitee  of notice of the
commencement of any Proceeding.  Indemnitee shall, if a claim in respect thereof
is to be made against the Company  under this  Agreement,  notify the Company of
the  commencement  thereof,  but the  omission so to notify the Company will not
relieve the Company from any liability that it may have to Indemnitee, except as
provided in Section 6(c).

        (b)  Defense.  With  respect to any  Proceeding  as to which  Indemnitee
notifies the Company of the commencement  thereof, the Company shall be entitled
to  participate  in the  Proceeding  at its own expense and except as  otherwise
provided below,  to the extent the Company so wishes,  it may assume the defense
thereof with counsel  reasonably  satisfactory to Indemnitee.  After notice from
the company to Indemnitee of its election to assume the defense


<PAGE>

of any  Proceeding,  the Company  shall not be liable to  Indemnitee  under this
Agreement or otherwise for any Expenses  subsequently  incurred by Indemnitee in
connection  with the defense of such Proceeding  other than reasonable  costs of
investigation or as otherwise provided below. Indemnitee shall have the right to
employ his or her own legal counsel in such Proceeding, but all Expenses related
thereto  incurred after notice from the Company of its assumption of the defense
shall be at Indemnitee's  expense unless: (i) the employment of legal counsel by
Indemnitee has been  authorized by the Company,  (ii)  Indemnitee has reasonably
determined that there may be a conflict of interest  between  Indemnitee and the
Company in the defense of the  Proceeding,  (iii) after  Change in Control,  the
employment  of  counsel  by  Indemnitee  has been  approved  by the  Independent
Counsel,  or (iv) the Company shall not in fact have employed  counsel to assume
the  defense  of such  Proceeding,  in each of which  case all  Expenses  of the
Proceeding  shall be borne by the Company.  The Company shall not be entitled to
assume the defense of any  Proceeding  brought by or on behalf of the Company or
as to which  Indmenitee shall have made the  determination  provided for in (ii)
above.

        (c)  Settlement of Claims.  The Company shall not be liable to indemnify
Indemnitee  under this Agreement or otherwise for any amounts paid in settlement
of any Proceeding  effected  without the Company's  written  consent,  provided,
however,  that if a Change in Control has occurred,  the Company shall be liable
for  indemnification  of  Indemnitee  for  amounts  paid  in  settlement  if the
Independent  Counsel has approved the  settlement.  The Company shall not settle
any  Proceeding  in any manner that would  impose any penalty or  limitation  on
Indemnitee  without  Indemnitee's  written consent.  Neither the Company nor the
Indemnitee will unreasonably  withhold their consent to any proposed settlement.
The Company shall not be liable to indemnify the Indemnitee under this Agreement
with regard to any judicial  award if the Company was not given a reasonable and
timely  opportunity,  at its  expense,  to  participate  in the  defense of such
action; he Company's  liability  hereunder shall not be excused if participation
in the Proceeding by the Company was barred by this Agreement.

     7.  Establishment  of  Trust.  In the  event of a Change  in  Control  or a
Potential  Change in  Control,  the  Company  shall,  upon  written  request  by
Indemnitee,  create a Trust for the benefit of the  Indemnitee  and from time to
time  upon  written  request  of  Indemnitee  shall  fund the Trust in an amount
sufficient to satisfy any and all Expenses reasonably anticipated at the time of
each such request to be incurred in  connection  with  investigating,  preparing
for,   participating  in,  and/or  defending  any  Proceeding   relating  to  an
Indenmifiable Event. The amount or amounts to be deposited in the Trust pursuant
to the foregoing funding  obligation shall be determined by the Reviewing Party.
The terms of the Trust  shall  provide  that upon a Change in  Control,  (i) the
Trust shall not be revoked or the principal thereof invaded, without the written
consent of the Indemnitee,  (ii) the Trustee shall advance,  within ten business
days of a request by the Indemnitee, any and all Expenses to the Indemnitee (and
the Indemnitee hereby agrees to reimburse the Trust under the same circumstances
for which the  Indemnities  would be required  to  reimburse  the Company  under
Section 2(c) of this  Agreement,  (iii) the Trust shall continue to be funded by
the Company in accordance with the funding  obligation set forth above, (iv) the
Trustee  shall  promptly  pay  to the  Indemnitee  all  amounts  for  which  the
Indemnitee shall be


<PAGE>


entitled to indemnification pursuant to this Agreement or otherwise, and (v) all
unexpended  funds  in the  Trust  shall  revert  to  the  Company  upon a  final
determination  by the Reviewing Party or a court of competent  jurisdiction,  as
the case may be, that the Indemnitee has been fully  indemnified under the terms
of this  Agreement.  The Trustee shall be chosen by the  Indemnitee.  Nothing in
this Section 7 shall  relieve the Company of any of its  obligations  under this
Agreement.  All income  earned on the assets held in the Trust shall be reported
as income by the Company for federal,  state,  local,  and foreign tax purposes.
The Company shall pay all costs of  establishing  and  maintaining the Trust and
shall indemnify the Trustee against any and all expenses  (including  attorney's
fees), claims, liabilities, loss, and damages arising out of or relating to this
Agreement or the establishment and maintenance of the Trust.

     8. Non-Exclusivity. The rights of Indemnitee hereunder shall be in addition
to any  other  right  Indemnitee  may  have  under  the  Company's  Articles  of
Incorporation, Bylaws, applicable law, or otherwise. To the extent that a change
in  applicable  law (whether by statute or judicial  decision)  permits  greater
indemnification  by  agreement  than  would  be  afforded  currently  under  the
Company's Articles of Incorporation.  Bylaws, applicable law, or this Agreement,
it is the intent of the parties  that  Indemnitee  enjoy by this  Agreement  the
greater benefits so afforded by such change.

     9. Liability  Insurance.  To the extent the Company  maintains an insurance
policy or policies  providing  directors'  and  officers'  liability  insurance,
Indemnitee  shall be covered by such policy or policies,  in accordance with its
or their terms, to the maximum extent of the coverage  available for any Company
director or officer.

     10. Period of Limitations. No legal action shall be brought and no cause of
action  shall be asserted by or on behalf of the Company or any affiliate of the
Company against Indemnitee,  Indemnitee's spouse, heirs,  executors, or personal
or legal  representatives  after the  expiration  of two years  from the date of
accrual of such cause of action,  or such  longer  period as may be  required by
state law under the  circumstances.  Any claim or cause of action of the Company
or its affiliate  shall be  extinguished  and deemed released unless asserted by
the timely filing of a legal action within such period; provided,  however, that
if any shorter period of  limitations is otherwise  applicable to any such cause
of action the shorter period shall govern.

     11. Amendment of this Agreement. No supplement,  modification, or amendment
of this Agreement  shall be binding  unless  executed in writing by both of  the
parties  hereto.  No waiver of any of the  provisions  of this  Agreement  shall
operate as a waiver of any other provisions hereof (whether or not similar), nor
shall  such  waiver  constitute  a  continuing  waiver.  Except as  specifically
provided herein,  no failure to exercise or any delay in exercising any right or
remedy hereunder shall constitute a waiver thereof.

     12. Subrogation.  In the event of payment under this Agreement, the Company
shall be  subrogated  to the  extent  of such  payment  to all of the  rights of
recovery  of  Indemnitee,  who shall  execute all papers  required  and shall do
everything that may be necessary to secure



<PAGE>


such rights,  including the execution of such documents  necessary to enable the
Company effectively to being suit to enforce such rights.

     13. No Duplication of Payments.  The Company shall not be liable under this
Agreement  to make any  payment  in  connection  with  any  claim  made  against
Indemnitee to the extent  Indemnitee has otherwise  received  payment (under any
insurance  policy,  Bylaw, or otherwise) of the amounts otherwise  indemnifiable
hereunder.

     14. Binding  Effect.  This Agreement shall be binding upon and inure to the
benefit  of and be  enforceable  by the  parties  hereto  and  their  respective
successors  (including  any direct or indirect  successor by  purchase,  merger,
consolidation,  or otherwise to all or substantially  all of the business and/or
assets  of the  Company),  assigns,  spouses,  heirs,  and  personal  and  legal
representatives.  The Company  shall  require and cause any  successor  (whether
direct or indirect by purchase,  merger,  consolidation,  or  otherwise) to all,
substantially  all, or a substantial  part, of the business and/or assets of the
Company, by written agreement in form and substance satisfactory to  Indemnitee,
expressly to assume and agree to perform  this  Agreement in the same manner and
to the same  extent  that the  Company  would be  required to perform if no such
succession had taken place.  The  indemnification  provided under this Agreement
shall  continue as to Indemnitee for any action taken or not taken while serving
in an indemnified  capacity  pertaining to an Indemnifiable Event even though he
or she may have ceased to serve in such capacity at the time of any Proceeding.

     15.  Severability.  If any provision (or portion thereof) of this Agreement
shall be held by a court of  competent  jurisdiction  to be  invalid,  void,  or
otherwise  unenforceable,  the remaining  provisions shall remain enforceable to
the  fullest  extent  permitted  by  law.  Furthermore,  to the  fullest  extent
possible, the provisions of this Agreement (including,  without limitation, each
portion of this Agreement containing any provision held to be invalid,  void, or
otherwise  unenforceable,  that is not itself invalid,  void, or  unenforceable)
shall be  constructed  so as to give  effect  to the  intent  manifested  by the
provision held valid, void or uneforceable.

     16.  Governing Law. This  Agreement  shall be governed by and construed and
enforced in accordance  with the laws of the State of  California  applicable to
contracts  made and to be performed in such State  without  giving effect to the
principles of conflicts of laws.

                                   EXHIBIT C
                               CYLINK CORPORATION

                          PROPRIETARY INFORMATION AND
                      INVENTIONS AND EMPLOYMENT AGREEMENT

     I  recognize  that  Cylink   Corporation   (the   "Company")  a  California
corporation,  is engaged in a continuous  program of research,  development  and
production  respecting  its  business,  present  and  future.  As  used  in this
Agreement, the term "Company" means Cylink Corporation, its successor companies,
subsidiaries and all affiliated  companies or operations in which it may have an
interest whether by stock ownership, joint venture arrangements or otherwise.

     I understand that:

     A. As part of my  employment  by the  Company,  I am  expected  to make new
contributions and inventions of value to the Company;

     B. My employment  creates a relationship of confidence and trust between me
and the Company with respect to any information:

        (1) Applicable to the business of the Company; or

        (2) Applicable to the business of any client or customer of the Company,
which may be made known to me by the Company or by any client or customer of the
Company, or learned by me in such context during the period of my employment.

     C. The Company possesses and will continue to possess  information that has
been created,  discovered,  developed,  or otherwise become known to the Company
(including, without limitation,  information created, discovered,  developed, or
made known by me during the period of or  arising  out of my  employment  by the
Company)  and/or in which  property  rights  have  been  assigned  or  otherwise
conveyed to the Company,  which information has commercial value in the business
in which the  Company  is  engaged.  All of the  aforementioned  information  is
hereinafter called "Proprietary  Information".  By way of illustration,  but not
limitation, Proprietary Information includes trade secrets,

                                      -1-


<PAGE>

processes, structures,  formulas, data and know-how,  improvements,  inventions,
techniques, marketing plans, strategies, forecasts, and customer lists.

     D. As used herein, the period of my employment includes any time in which I
may be retained by the Company as a consultant.

     In consideration of my employment or continued employment,  as the case may
be, and the  compensation  received by me from the Company  from time to time, I
hereby agree as follows:

     1. All  Proprietary  Information  shall be the sole property of the Company
and its assigns,  and the Company and its assigns shall be the sole owner of all
patents and other rights in connection therewith. I hereby assign to the Company
any right I may have or acquire in such Proprietary  Information.  At all times,
both during my employment by the Company and after its termination,  I will keep
in  confidence  and trust  all  Proprietary  Information,  and I will not use or
disclose any Proprietary Information or anything directly relating to it without
the written  consent of the Company,  except as may be necessary in the ordinary
course of  performing  my duties as an employee of the Company.  Notwithstanding
the  foregoing,  it is understood  that, at all such times, I am free to use (a)
information  in the public domain not as a result of a breach of this  Agreement
and (b) my own skill, knowledge,  know-how and experience to whatever extent and
in whatever way I wish.

     2. I agree that  during the period of my  employment  by the Company I will
not, without the Company's express written consent,  engage in any employment or
business other than for the Company.

     3. In the event of the termination of my employment by me or by the Company
for any reason,  I will deliver to the Company all  documents  and data (whether
written or  electronically  stored) of any nature pertaining to my work with the
Company and I will not take with me or deliver to anyone else any  documents  or
data of any description or any  reproduction  of any  description  containing or
pertaining to any Proprietary Information.

     4. I will promptly  disclose to the Company,  or any persons  designated by
it,  all  improvements,   inventions,   designs,  ideas,   copyrightable  works,
discoveries, trade marks, copyrights, trade secrets, formulas, processes,

                                      -2-


<PAGE>


techniques,  know-how, and data, whether or not patentable, made or conceived or
reduced to  practice  or learned by me,  either  alone or jointly  with  others,
during  the  period  of my  employment  which  are  related  to or useful in the
business  of the  Company,  or result  from tasks  assigned me by the Company or
result from use of premises owned, leased, or contracted for by the Company (all
said improvements, inventions, designs, ideas, copyrightable works, discoveries,
trade marks,  copyrights,  trade  secrets,  formulas,   processes,   techniques,
know-how, and data shall be collectively hereinafter call "Inventions").

     5. I agree that all  Inventions  shall be the sole  property of the Company
and its assigns,  and the Company and its assigns shall be the sole owner of all
patents and other rights in connection therewith. I hereby assign to the Company
any rights I may have or acquire in such  Inventions.  I further agree as to all
such  Inventions to assist the Company in every proper way (but at the Company's
expense) to obtain and from time to time enforce  patents on said  inventions in
any and all  countries,  and to that end I will execute all documents for use in
applying for and  obtaining  such patents  thereon and  enforcing  same,  as the
Company  may desire,  together  with any  assignments  thereof to the Company or
persons  designated  by it. My obligation to assist the Company in obtaining and
enforcing  patents for such  Inventions in any and all countries  shall continue
beyond the termination of my employment,  but the Company shall compensate me at
a reasonable  rate after such  termination  for time actually spent by me at the
Company's request on such assistance.

     Any  provision  in this  Agreement  requiring me to assign my rights in any
invention  does not  apply to an  invention  which  qualifies  fully  under  the
provisions of Section 2870 of the California  Labor Code. That section  provides
as follows:

          Any  provision  in an  employment  agreement  which  provides  that an
     employee shall assign,  or offer to assign,  any of his or her rights in an
     invention to his or her employer  shall not apply to an invention  that the
     employee  developed  entirely  on his or her own  time  without  using  the
     employer's  equipment,  supplies,  facilities,  or trade secret information
     except for those inventions that either;

                                      -3-


<PAGE>


          (1) Relate at the time of  conception  or reduction to practice of the
     invention to the employer's business, or actual or demonstrably anticipated
     research or development of the employer.

          (2) Result from any work performed by the employee for the employer.

I  acknowledge  that receipt and execution of this  Agreement by me  constitutes
written notification,  as required by Section 2872 of the California Labor Code,
regarding above Section 2870 and its protective effect on certain  inventions by
me.

     6. As a matter of record I have identified on Exhibit A attached hereto all
inventions or  improvements  relevant to the subject  matter of my employment by
the Company which have been made or conceived or first reduced to practice by me
alone or jointly with others  prior to my  engagement  by the  Company,  which I
desire to remove from the operation of this Agreement;  and I covenant that such
list is complete. If there is no such list on Exhibit A, I represent that I have
made no such inventions and improvements at the time of signing this Agreement.

     7. I represent  that my  performance of all the terms of this Agreement and
as an employee of the Company does not, to the best of my present  knowledge and
belief,  and  will  not  breach  any  agreement  or duty  to keep in  confidence
proprietary  information  acquired by me in  confidence  or in trust prior to my
employment by the Company. I have not entered into, and I agree I will not enter
into, any agreement either written or oral in conflict herewith.

     8. I understand  as part of the  consideration  for the offer of employment
extended to me by the Company and of my  employment  or continued  employment by
the Company, that I have not brought and will to bring with me to the Company or
use in the  performance of my  responsibilities  at the Company any materials or
documents of a former employer which are not generally  available to the public,
unless I have obtained written  authorization from the former employer for their
possession and use.

     Accordingly,  this is to advise  the  company  that the only  materials  or
documents of a former  employer which are not generally  available to the public
that I will bring to

                                      -4-


<PAGE>


the Company or use in my employment are identified on Exhibit A attached hereto,
and as to  each  such  item,  I  represent  that I have  obtained  prior  to the
effective data of my employment with the Company written authorization for their
possession and use in my employment with the Company.

     I also  understand  that,  in my employment  with the Company,  I am not to
breach  any  obligation  of  confidentiality  or  duty  that  I have  to  former
employers,  and I agree  that I shall  fulfill  all such  obligations during  my
employment with the Company.

     9. I agree that the Company is not by reason of this Agreement obligated to
continue me in its employment.

     10. I agree that any breach of this Agreement by me would cause irreparable
damage to the Company and that,  in the event of such breach,  the Company shall
have,  in addition to any and all remedies of law,  the right to an  injunction,
specific  performance or other  equitable  relief to prevent the violation of my
obligations hereunder.

     11. If any provision hereof shall be declared unenforceable for any reason,
such  unenforceability  shall not affect  the  enforceability  of the  remaining
provisons  of this  Agreement.  Further,  such  provision  shall be reformed and
construed to the extent  permitted  by law so that it would be valid,  legal and
enforceable to the maximum extent possible.

     12. This Agreement  shall be effective as of the first day of my employment
by the Company, namely:________________________________________________________.

     13. This Agreement shall be binding upon me, my heirs, executors,  assigns,
and  administrators,  shall inure to the benefit of the Company,  is successors,
and assigns and shall survive my employment by the Company.
