                                     PART I


ITEM 1.  DESCRIPTION OF BUSINESS

General

         Datakey,  Inc. (the "Company") was  incorporated  under the laws of the
State of Minnesota in 1976 under the name "The Systems Group, Inc." In 1980, the
Company  changed  its  name to  Datakey,  Inc.  The  Company  provides  product,
subsystem  and  system  solutions  to  record,  store  and  transmit  electronic
information.  Datakey also  manufactures and sells products and systems directed
to the  information  security market which will enable user  identification  and
authentication,  secure  data  exchange  and  information  validation.  It  also
provides OEM products,  consisting of proprietary  memory keys,  cards and other
custom-shaped  tokens  that  serve  as a  convenient  way  to  carry  electronic
information and are packaged to survive in portable environments.

         The  Company's  first  portable  information  system,  consisting of an
electronic key and support electronics,  was introduced in 1981 for applications
requiring convenient storage,  transportation and management of information. The
Company's current system utilizes semiconductor  technology to provide a storage
device more versatile than conventional  portable  information  products such as
keys,  badges and magnetic stripe cards.  The Company's  current product line of
portable  data  carriers  and  associated   interface  products  provide  up  to
16,384,000  bits of data storage which are used in a wide range of  applications
including communications security, computer security, facility security, vending
and process control.

         Each of the Company's personal portable information systems consists of
one or more  portable data  carriers,  access  devices and, for certain  models,
interface modules containing  microprocessors.  These components,  together with
the user's processor-based equipment,  function as an integrated system allowing
instantaneous  processing of  personalized  data carried  within a portable data
carrier.  Through the incorporation of advanced semiconductor memory technology,
the  Company's  portable  data  carrier  is able to store and carry  substantial
amounts of  information.  When the portable data carrier is used in  conjunction
with  the  other  components  of  the  Company's  system,   information  can  be
selectively  altered,  added to or  erased,  as  required,  to  effectively  and
reliably manage or control a particular activity or transaction.

         The Company has  introduced  an end-user  system level product which is
designed to provide  electronic  signatures  on computer  aided  drafting  (CAD)
drawings and additional  end-user  systems that are designed to provide advanced
information security utilizing digital signatures and encryption.  These systems
incorporate  hardware and software to provide a higher level of security than is
obtainable with current software only solutions.

Current Products and Products Under Development

Electronic Products

         Portable Data Carrier  Devices.  Portable data carriers are  electronic
memory devices which store information. They have a plastic exterior, are in the
forms of keys,  cards,  or custom  shaped tokens and  encapsulate  semiconductor
memory.  Certain  devices have been designed to store  information  which may be
retrieved, altered, erased or updated; while other devices have been designed to
store one-time  programmable  information which may be retrieved but not altered
or updated.  The storage  capacities of the Company's  portable  memory  devices
range from 1,024 bits (150  alphanumeric  characters)  to 16,384,000  bits.  The
portable  data  carriers  are  priced  generally  between  $2 and $100 per unit,
depending on capacities and quantities purchased.


<PAGE>

         Access  Device.  The access device is the element into which a portable
data  carrier is inserted to provide the  interconnection  between the  portable
data carrier and the electronic  interface circuitry or the host processor-based
equipment.  It is through this physical  interconnection that the data contained
in the portable data carrier's memory is transmitted to the electronic interface
or to the  host  interface.  Several  models  of the  access  device  have  been
developed to handle the Company's  different portable data carriers.  The access
devices are priced generally between $15 and $120 per unit,  depending on models
and quantities purchased.

         Interface.  The interface is the electronics control module between the
access device and a customer's  processor-based  equipment.  This module is used
with the  Company's  serial  communication  key and contains  all the  necessary
electronics  to  control  information  within  the  key  and to  coordinate  the
information  requests  of the host  equipment.  This  communication  process  is
managed by the system's  firmware,  which is a software  program existing within
the interface.  For some  applications,  this firmware  structures,  secures and
verifies the  information  within the portable  device,  and may allow  separate
groups or files of data to reside in a single portable device and be secure from
access except by equipment  authorized  to manage a particular  group or file of
data. The interface is priced between $70 and $120 per unit, depending on models
and quantities purchased.

Integrated System Solutions

         For the past two years,  Datakey has been  developing new products that
provide advanced security solutions to the problems of organizations, worldwide.
The  first  release  of  these  token-based  information  security  systems  was
introduced  in  September  1997  and  additional  versions  are  expected  to be
introduced in the first half of 1998. The launch and success of such products is
dependent on further successful development efforts and market acceptance, along
with other risks. See "Forward Looking Statements."

         SignaSURE  CIP.   Password-based   software   programs  that  implement
public-key   cryptography  technology  for  information  security  offer  easier
operation  and  improved  data  integrity  over  older  symmetric   cryptography
software. Password-based security, however, is insufficient for private networks
with  connections  outside  of the  corporation.  The  Company's  SignaSURE  CIP
(Cryptographic  Interface Provider) is designed to solve this problem,  allowing
the Internet to be used safely for electronic commerce.

         SignaSURE CIP allows users and  value-added  resellers to upgrade their
software-only  systems to token-based  information security and gain the benefit
of secure Internet  operation.  Token-based  information  security  implements a
two-level  security  scheme--something  that is owned  (a  hardware  token)  and
something that is known (a password to activate the  token)--for a much stronger
level of security than password-based software solutions. SignaSURE CIP provides
token upgrades for Cryptoki or PKCS-11 standard  information  security interface
applications and for applications that incorporate Microsoft's CryptoAPI.  These
products  offer  "load,  plug  and  play"  convenience  for  strong  information
security.

         SignaSURE CIP products  include a  user-unique  smart card or smart key
that holds the  critical  information  to perform  the  cryptographic  functions
necessary for information privacy and data integrity, a companion  reader/writer
that plugs into a computer's  serial port, PCMCIA port or floppy disk drive, and
software which is loaded into the  workstation and interfaces to the application
program.  The Company introduced,  in September 1997, a version of SignaSURE CIP
that utilizes the standard PKCS #11 (Cryptoki) Interface and plans to release in
early 1998 a version that utilizes Microsoft's CryptoAPI.


<PAGE>

         SignaSURE  DTK. As  public-key  information  security  grows due to the
technology's  adoption by well-known  software  companies  such as Microsoft and
Netscape,   smaller  software   developers  are  also  implementing   public-key
information security into their specialized applications. Because no easy method
was  available  for smaller  application  developers  to implement a token-based
public key  infrastructure,  the Company developed its SignaSURE DTK (Developers
Tool Kit) so that  developers  could  easily and  cost-effectively  launch their
applications with the much stronger, token-based information security.

         SignaSURE DTK is a turnkey  package that the Company  designed to allow
software  developers  to  integrate  Datakey  hardware  tokens and a  public-key
infrastructure  into  their   applications.   DTK  includes  up  to  three  main
components:  hardware  cryptographic tokens,  interface and integration software
and security  infrastructure  products.  DTK is available in four configurations
ranging from just a token with a reader/writer and integration  software, to the
full public-key  infrastructure  configuration  that issues and manages hardware
tokens and digital certificates. This product flexibility allows user-developers
who  utilize   SignaSURE  DTK  to  integrate  just  what  is  needed  for  their
application. The Company began selling the SignaSURE DTK in mid-1997.

         SignaSURE EDM. Design and drafting was  revolutionized  several decades
ago with the  introduction of computer  aided-design  (CAD)  software.  However,
engineers still must print their CAD-created designs, approve the documents with
hand-written  signatures,  and archive these  hand-signed  originals to maintain
change  control and ensure  design  traceability.  The  Company's  SignaSURE EDM
(Electronic  Document  Manager),  which  Datakey  began  to sell  in late  1996,
provides a way to sign an electronic  document to ensure its authenticity,  thus
eliminating  the need  for  hand-signed  originals  and all of the  storage  and
archiving requirements for paper-based engineering drawings and documents.

         SignaSURE  EDM adds digital  signatures  to CAD and other  documents to
ensure document authenticity,  configuration control and conformance to ISO 9000
document   management   requirements.   SignaSURE   EDM  provides  for  copying,
distributing and archiving of electronically generated documents with a level of
authenticity  formerly  obtainable only with  hand-signed  paper  documents.  It
answers  questions of document  authorship,  integrity and culpability  quickly,
easily and  unambiguously.  With SignaSURE EDM, documents in electronic form can
be transmitted  over local area networks,  intranets and the Internet with their
authenticity assured.

         SignaSURE  EDM  includes a smart card or smart key that  generates  the
user's digital signature, a companion reader/writer that plugs into a computer's
serial  port,  and a  software  program  which is loaded  into the  workstation.
SignaSURE EDM operates on all Windows operating systems,  is compatible with all
CAD  programs  and file  formats,  and moves  design and drafting to a paperless
environment.  A new SignaSURE version of EDM with a more "windows like" look and
feel is scheduled for release in the second quarter of 1998.

         SignaSURE ESS. Many of today's  organizations  have made the transition
from  large  mainframe   systems  to  more  flexible,   but  much  less  secure,
client-server networks and intranets. Client-server networks and intranets allow
digital  information  to reside  on  networks,  rather  than at the  desktop  so
authorized users can access the same  information.  Authorized users can include
company employees,  suppliers and customers who can be connected to the network,
or  located  remotely  from the  enterprise.  With the  advent of the  Internet,
information  transmission over any distance can be accomplished quickly and cost
effectively,  but not securely.  Datakey  believes its SignaSURE ESS (Enterprise
Security  Suite)  offers a solution to manage a network,  intranet  and Internet
computing  structure to allow authorized users ready access to information,  but
deny it to the  unauthorized.  Information can then be transmitted  securely and
stored  safely on both  private  and public  networks  without  privacy and data
integrity concerns.


<PAGE>

         SignaSURE ESS is an integrated end-to-end data security system that the
Company  believes will assure secure network  access,  confidential  information
exchange,   integrity   of  data  and   transaction   non-repudiation.   Secure,
personalized  smart tokens are employed  within a public key  infrastructure  to
provide a higher level of information security than is provided by software-only
solutions.  Security  functions are integrated into  applications like Microsoft
Office(TM), thereby providing seamless security operation to the user. SignaSURE
ESS will operate over the Internet,  and wide and local area  networks  enabling
secure  information  exchange  for all  users,  whether  local or  remote to the
enterprise.

         SignaSURE  ESS  includes  a  user-personalized  smart card or smart key
hardware  token and  companion  reader/writer  for  workstation  or laptop  that
perform the functions necessary for information  privacy and data integrity.  It
also incorporates client software that manages secure information and interfaces
to  applications,  and  server-based,  enterprise  infrastructure  hardware  and
software that  initialize  SignaSURE ESS and  continually  ensures all users are
authorized.  The Company  expects to begin  selling  SignaSURE ESS in the second
quarter of 1998.

Year 2000

         The Company's  products are designed on an operating  system which uses
four digits in designating the year. As a result, these products can distinguish
the year  2000  from the year  1900;  therefore,  the year  2000  will not cause
problems.


Research and Development

         During 1997,  the Company  continued the  development  of portable data
carriers  to expand  its line of  standard  products  as well as newly  designed
custom  products.  The Company also  substantially  increased its development of
token-based information security products.

         As the need for  computer  security  products  continues  to grow,  the
Company has been expending  significant  effort into  development of token-based
computer   information   security  systems.  The  Company's  SignaSURE  line  of
information  security  products,  which were initially  released for sale during
1997,  are designed to provide  encryption and digital  signatures  required for
electronically generated documents on computer networks.


<PAGE>

         The  technology  involved in  information  systems in undergoing  rapid
expansion and advancement  which could result in the development of new products
and systems which may make the Company's present  information  security products
obsolete.  The initial development effort for the Company's information security
products  was  completed  in 1997 but the Company  must  continue to improve its
present information security products in order to remain competitive.

         In  1997,  1996  and  1995,  research  and  development  expenses  were
$3,186,000,  $2,263,000  and $704,000,  respectively.  The Company  expects that
research and development expenses in 1998 will be about 45% less than in 1997.

Manufacturing

         The   Company's    in-house    manufacturing    capabilities    include
microelectronic  assembly,  plastic injection  molding,  automated surface mount
assembly, and general electronic assembly. The Company also utilizes independent
subcontractors from time to time to perform certain manufacturing functions. The
Company  provides a 90-day  warranty on domestic  sales,  a 180-day  warranty on
sales to its  international  distributors  to cover the longer shelf life of the
Company's products, and a 180-day warranty on sales to the government.

         In an effort to more efficiently  produce  products,  to reduce product
costs,  and to increase its  manufacturing  flexibility,  the Company intends to
continue to improve certain manufacturing processes and add capital equipment to
its manufacturing  operations.  While the Company believes that these steps will
provide a greater level of control over, and flexibility  in, its  manufacturing
processes,  there  are no  assurances  that the  Company's  ability  to  produce
products and to meet required delivery  schedules will be sufficiently  improved
to meet the demands  created by increased  sales and more complex  manufacturing
processes.

Sources of Supply

         The Company  purchased  microprocessors  for its  advanced  information
security  products (the SignaSURE  line of products)  from a single  supplier in
1997. This supplier also provided a proprietary  card and key (token)  operating
system which will be discontinued after the current supply of microprocessors is
depleted.  The Company has also  developed its own  proprietary  card  operating
system which is "masked" into a new  microprocessor.  The new  microprocessor is
being  purchased  from a different  single  supplier,  will be placed into smart
cards and smart keys and introduced to the  marketplace  when the current supply
of microprocessors is depleted.

         Due to the unique nature of these cryptographic microprocessors,  there
are  currently a limited  number of  alternative  sources of supply and,  due to
different   operating   systems  and  other   characteristics,   one  supplier's
microprocessors  are not  easily  interchanged  with  another.  Should the newly
arranged  source of supply become  inadequate or inferior to other  offerings in
the  future,  the  Company  will be  required  to incur a  significant  cost and
possibly experience a gap in supply to switch to a new supplier.

         The  Company  has  several  qualified  sources  from which to  purchase
printed  circuit  boards  and  electronic  components  for most of its  standard
portable  data  carriers.  The  components  for the  Company's  products are, in
general,  available from multiple suppliers.  Some of the plastic components are
molded  on the  Company's  in-house  molding  equipment  or  suppliers'  molding
equipment using Company-owned tooling.


<PAGE>

         The Company purchases  integrated circuits primarily through nationwide
multivendor  distributors.  If, for any reason, the Company would have to cancel
or reduce a particular integrated circuit order, it might thereafter have to pay
a higher price for the integrated  circuits.  Since general economic  conditions
have an  effect  on the  supply  and cost of  integrated  circuits,  there is no
guarantee  that  the  Company  will be able to  obtain  adequate  quantities  of
integrated  circuits to meet all of its production needs during periods of short
supply.

Significant Customer

         The Company  sells its  electronic  products to a number of  commercial
original  equipment   manufacturers   (OEMs)  and  other  customers,   including
governmental  entities.  At this time,  the Company is not  dependent on any one
customer  or few  customers,  the loss of which  would have a  material  adverse
effect on its business.

Marketing

         General.  While there appears to be a broad range of  applications  and
potential customers for portable data carriers,  no single application group has
evidenced  strong,  long-term  growth  potential.  The  diversity  of  potential
applications  has  made it  difficult  for the  Company  to  focus  its  limited
marketing  resources.   In  1995,  sales  to  OEM  customers  increased  23%  to
$7,219,000, in 1996 they decreased 9% to $6,559,000,  and in 1997 they decreased
11% to $5,868,000.  The Company  believes that commercial OEM sales may decrease
again in 1998.

         New end-user  products  being  developed for the  information  security
marketplace  were introduced in 1997 and, based upon current  expectations,  are
expected to result in material  revenue  during the second half of 1998. As with
any new product line, revenue will depend on customer acceptance,  the extent of
which is difficult to assess at this time.

         Market of OEM Products.  To date,  most  applications in the commercial
and  government  market  have  used  the Data Key for  electronic  security  and
equipment  control  applications.  The  Company  is  seeking  to  develop  other
long-term  business in this  market.  The Company  markets its  products to both
domestic and international customers using the following channels.

                  Domestic.   The  Company  markets  its  portable   information
products  domestically  through a  combination  of  direct  and  indirect  sales
personnel. In addition, it utilizes advertising,  trade shows and direct mail to
reach  its  buying  audience.  In 1997,  1996 and 1995,  OEM  sales to  domestic
customers, and the corresponding percentage of total revenue, were approximately
$4,068,000 (68%), $4,653,000 (71%) and $5,312,000 (74%), respectively.

                  International.  The Company  presently  markets  its  portable
information products  internationally  through an independent sales agent in the
United Kingdom and agents and/or distributors in Columbia,  Australia,  Belgium,
the  Netherlands  and Germany.  The Company has customers in other countries who
are  handled on a direct  basis from the  Company's  headquarters  in the United
States. The Company intends to expand into other  international  market areas in
the future.  In 1997, 1996 and 1995, OEM sales to international  customers,  and
the corresponding  percentage of total revenue,  were  approximately  $1,800,000
(30%), $1,906,000 (29%) and $1,907,000 (26%), respectively.

End-User Products

         Datakey  plans to market  and sell its  advanced  information  security
products  (the  initial  offerings  in its  end-user  systems  line)  through  a
combination  of direct sales and  marketing  personnel,  dealers,  distributors,
value added resellers and system integrators/developers.

         The direct sales and marketing personnel will concentrate  primarily on
relationships with large security-conscious  organizations either through direct
or indirect contact,  establishing alliances with system  integrators/developers
and setting up  dealer/distributor  relationships  for its products.  The future
revenue of Datakey  end-user  systems is  dependent  on the success of a new and
untested  marketing  and  direct  sales  organization.   Also,  see  "Risks  and
Uncertainties"  in the  Management's  Discussion  and Analysis  contained in the
Company's 1997 Annual Report,  portions of which are included in Exhibit 13.1 of
this Report.

Backlog

         As of  March 9,  1998,  the  Company  had an  order  backlog,  totaling
approximately  $3,047,000,   including  approximately  $404,000  with  scheduled
shipment dates in 1999,  compared to $4,127,000 a year ago,  $1,187,000 of which
were  scheduled  for  shipment in 1998.  Although the orders  contain  scheduled
shipment dates,  they may be accelerated,  delayed or canceled at the customer's
request.  The Company does not believe that the current  backlog is  necessarily
indicative of future backlog levels.

Competition

         Electronic   Products.   The  Company's  primary  competition  for  its
electronic  products  sold to OEMs is  presently,  and is  expected  to  remain,
conventional  portable  information  systems,  such as keys and cards,  and more
advanced  portable  information  systems  including those in the familiar credit
card format,  such as "smart  cards,"  Personal  Computer  Memory Card  Industry
Association  (PCMCIA)  cards,  magnetic  stripe cards,  bar-code cards and laser
technology cards. The Company's products, when used as a portable data base, may
also compete with  centralized data base systems.  Many of the  manufacturers of
these  portable  information  devices and  systems  are large,  well-established
companies.

         A number of European and Japanese  firms continue to develop and refine
the smart card  technologies.  Some of these companies have  established  branch
offices in the United States to explore the United States  market.  To date, the
smart card has been used primarily in Europe,  where it has been  implemented in
prepaid telephone systems. In the United States, smart cards are currently being
used  mainly in field trial  environments.  Although  the Company  does not have
complete  information  about the status of these  trials,  the Company  believes
that, in time, the smart card will be successfully  developed and could become a
competitor,  especially in those markets which have a history of using a card or
a preference for card-type devices.

         Memory  cards,   such  as  PCMCIA  standard  cards,   are  functionally
equivalent  to the  Company's  portable  data  carriers  in  that  they  utilize
semiconductor  memory in  card-shaped  devices  made of  plastic.  Memory  cards
generally have larger memory  capacities than the devices  currently  offered by
the  Company  and  historically  incorporated  volatile,  battery-backed  memory
elements.  More  recently,   nonvolatile  (principally  "Flash  Memory")  memory
elements which do not require  battery backup have become more  prominent.  They
are  used  in  such  applications  as  laser  printer  fonts,   instrumentation,
electronic lettering machines and fax/modems,  and are also used as replacements
or "add ons" to diskettes  and hard drives for data storage in certain  desktop,
notebook and smaller portable computers.


<PAGE>

         Magnetic   stripe  cards  are  relatively   inexpensive  and  are  used
extensively  in the access  control  industry and in the banking and credit card
industries.  These markets are not priority  markets for the Company's  portable
information devices.  Magnetic stripe cards are not conveniently  updated,  have
limited  storage  capacity and generally have a useful life of one or two years.
As a result, the Company believes its products are technologically  superior and
may be more cost-effective for applications requiring more complex technologies.

         Another  technology  utilizes a strip of reflective  material  which is
laminated into a card.  Information is inscribed on this material through use of
a laser beam. Since these cards can contain several million bits of information,
the Company  believes  that this  technology  will be a  competitor  in portable
information markets where very large information storage capacities are required
and instantaneous management of information is not essential.

         The  Company's  ability to compete in the portable  information  market
will depend primarily on its ability to demonstrate superior product performance
at  cost-effective  prices and on the enhanced features of its system which make
it more effective than competing systems.

         Integrated  System  Solutions.  Datakey  currently  offers  token-based
(smart  card,  smart  key)  information  security  systems  which are  primarily
utilized in encryption  for  electronic  mail  privacy,  private and secure file
transfer and digital  signatures for  electronic  document  authentication.  The
Company also sells a digital  signature  based product,  known as SignaSURE EDM,
which  enables  users  to  electronically  sign  computer-aided  drafting  (CAD)
documents. The Company is continuing a significant product development effort to
expand the  applications  and  ease-of-use  of its  products  and  systems.  See
"Products--Integrated System Solutions."

         Competition  in  the  information  security  business  is  varied  with
companies  offering hardware  solutions,  software solutions and combinations of
hardware and software  solutions.  As  awareness  for security on the  Internet,
company  intranets and on other local area networks has increased  over the past
few years,  many  companies  have  introduced  software  and/or  hardware  based
products to provide security.  These products range from software-based password
only systems to firewalls,  which may be very sophisticated.  Other applications
are using hand held hardware devices, commonly referred to as tokens, to provide
access to networks and, in some cases, use encryption and digital  signatures to
further secure networks.

         The Company's advanced information security products, some of which are
released and some of which are currently in development,  are based upon a smart
card or smart key and  utilize  encryption  and  digital  signatures.  They also
include  extensive  software to make the system  user-friendly and seamless with
common desktop software  packages.  The Company feels this will provide a unique
combination of advanced security features at a reasonable  selling price.  There
are several companies  operating in this highly competitive and rapidly changing
marketplace,  however,  and many of such companies have strong name  recognition
and vast financial  resources.  The Company believes it can compete on the basis
of its unique  design and ease of use. The initial  reception  to the  Company's
products in the  marketplace,  beginning in late 1997, has been  encouraging and
sales of evaluation  units and units for pilot  programs  have been  progressing
very  well.  There are no  assurances,  however,  that the  existing  and future
products will, in the long term, be accepted in the marketplace.

Patents and Trademarks

         The  Company  has been  granted  several  patents by the United  States
Patent and Trademark  Office relative to the Data Key, its key interface and its
overall portable information device technology. The Company has sought and will,
when  appropriate,  continue  to  seek  patent  protection  in  several  foreign
countries.  The federal  registration  of the Datakey  trademark was approved in
1985. The Company also has patents in application or in the filing  process.  In
an industry  characterized by rapid  technological  change, the Company believes
that the knowledge,  experience and creativity of its employees will prove to be
more important than patent protection.

Employees

         The Company  presently employs 55 full-time  employees,  14 of whom are
involved in manufacturing,  5 in materials handling, 3 in quality assurance,  14
in engineering, 11 in marketing/sales and 8 in general and administrative areas.
In addition,  the Company uses contract labor during peak  production  times and
for major  projects.  The  Company's  employees  are not subject to a collective
bargaining  agreement,  and the Company believes that its employee relations are
good.

Forward Looking Statements

Certain  statements  made in this Form 10-KSB,  which are  summarized  here, are
forward-looking  statements  that  involve  risk and  uncertainties,  and actual
results may be materially different.  Factors that could cause actual results to
differ include, but are not limited to those identified:

- --   The  expectation  that  Datakey  in the first  half of 1998 will  introduce
     additional versions of its token-based  information security systems, a new
     version of SignaSURE  CIP, and a new version of SignaSURE EDM is subject to
     the risk of  unanticipated  problems or delays in  development  and depends
     upon  market  acceptance  and  demand,  as well  as  other  general  market
     conditions and  competitive  conditions  within this market,  including the
     introduction of products by competitors.

- --   The expectation that Datakey will begin to sell SignaSURE ESS in the second
     quarter of 1998 depends upon successful development efforts and meeting the
     currently scheduled timetable for such development.

- --   The expectation that the Company will continue to improve its manufacturing
     processes,  leading to more efficient production,  depends on the Company's
     ability to monitor  such  processes  and to add  capital  equipment  to its
     manufacturing operations.

- --   The expectation that the Company will expand sales in international markets
     depends on the acceptance of its products in such markets,  the quality and
     performance of the Company's products as compared to competitive  products,
     the  effectiveness  of relatively  new marketing and sales  personnel,  and
     other general market and competitive conditions within such markets.

ITEM 2.  DESCRIPTION OF PROPERTY

         The Company's corporate offices and manufacturing facility,  located at
407 West Travelers Trail, Burnsville, Minnesota, consists of 18,488 square feet.
Approximately  one-half of the space is used for  manufacturing and warehousing,
and the balance for present and future office space. All of this space is rented
under a lease  which  extends  through  June 1999.  The  Company  also  utilizes
approximately 2,400 square feet in a nearby office under a sublease that expires
in May 1999.  The  annual  rent  expense  for the space  currently  occupied  is
$156,000,  plus a portion of the operating  expenses and real estate taxes.  The
Company  believes  its  space is  sufficient  for its  needs in the  foreseeable
future, and it believes its property is adequately insured.

                          INDEPENDENT AUDITOR'S REPORT



To the Stockholders
Datakey, Inc.
Burnsville, Minnesota



We have audited the accompanying  consolidated  balance sheets of Datakey,  Inc.
and  Subsidiary as of December 31, 1997 and 1996,  and the related  consolidated
statements of operations,  stockholders'  equity, and cash flows for each of the
three years in the period ended December 31, 1997. These consolidated  financial
statements   are  the   responsibility   of  the   Company's   management.   Our
responsibility  is  to  express  an  opinion  on  these  consolidated  financial
statements based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable  assurance about whether the  consolidated  financial  statements are
free of material  misstatement.  An audit includes  examining,  on a test basis,
evidence  supporting the amounts and disclosures in the  consolidated  financial
statements.  An audit also includes assessing the accounting principles used and
significant  estimates  made by  management,  as well as evaluating  the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

In our opinion, the consolidated  financial statements referred to above present
fairly, in all material respects,  the financial  position of Datakey,  Inc. and
Subsidiary as of December 31, 1997 and 1996, and the results of their operations
and their cash flows for each of the three  years in the period  ended  December
31, 1997, in conformity with generally accepted accounting principles.

Note 1.  Nature of Business and Significant Accounting Policies

Nature of business:  Datakey,  Inc. is an  international  supplier of electronic
products and services. The Company designs,  manufactures, and markets products,
subsystems,  and systems  solutions to record,  store,  and transmit  electronic
information.  The Company is  developing  products  and systems  directed to the
information   security  market  which  will  enable  user   identification   and
authentication,  secure data exchange, and information  validation.  The Company
also provides OEM products,  consisting of proprietary  memory keys,  cards, and
other  custom-shaped  tokens, that serve as a convenient way to carry electronic
information and are packaged to survive in portable environments.  The Company's
practice is to grant credit on an unsecured  basis to customers who meet certain
financial criteria.

A summary of significant accounting policies follows:

Principles of consolidation:  The consolidated  financial statements include the
accounts of Datakey,  Inc.  and its  wholly-owned  subsidiary.  All  significant
intercompany accounts and transactions have been eliminated in consolidation.

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 the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates.

Cash and cash  equivalents:  For purposes of reporting  the  statements  of cash
flows,  the  Company  includes  all cash  accounts  and all highly  liquid  debt
instruments  purchased with an original maturity of three months or less as cash
and cash equivalents on the accompanying consolidated balance sheets.

The Company  maintains its cash in bank deposit  accounts which,  at times,  may
exceed federally  insured limits.  The Company has not experienced any losses in
such accounts.

Fair value of financial instruments: The Company's financial instruments consist
of cash and cash equivalents and short-term  trade  receivables and payables for
which current carrying amounts approximate fair market value.

Inventories:  Inventories are stated at the lower of cost  (first-in,  first-out
method) or market.

Licenses and patents: Licenses and patents are stated at cost. Patents are being
amortized using the straight-line  method over their economic useful lives which
has been  estimated  to be five years.  The cost of the license  agreements  are
amortized to cost of goods sold as the products incorporating the licensed units
are sold (Note 8).

The Company periodically  reviews the utilization of its licenses,  patents, and
long-lived  assets for  impairment.  To date,  management has determined that no
impairment in the value of these assets has occurred.

<PAGE>


Note 1. Nature of Business and Significant Accounting Policies
(Continued)

Depreciation:  Depreciation of equipment and leasehold  improvements is computed
on the straight-line and accelerated methods over the following estimated useful
lives:

                                       Years

Production tooling                      2-5

Equipment                               5-7

Furniture and fixtures                    7

Leasehold improvements                 Life of lease


Warranty costs:  The Company provides for estimated normal warranty costs at the
time of product  sales to the  customers  and for other  costs  associated  with
specific items at the time their existence and amounts are determinable.

Income taxes: Deferred taxes are provided on a liability method whereby deferred
tax assets are  recognized for deductible  temporary  differences  and operating
loss or tax credit  carryforwards,  and deferred tax  liabilities are recognized
for taxable  temporary  differences.  Temporary  differences are the differences
between  the  amounts  of assets  and  liabilities  recorded  for income tax and
financial  reporting  purposes.  Deferred  tax assets are reduced by a valuation
allowance when  management  determines that it is more likely than not that some
portion or all of the  deferred  tax assets will not be  realized.  Deferred tax
assets and  liabilities  are adjusted for the effects of changes in tax laws and
rates on the date of enactment.

Revenue  recognition:  The Company  records  sales  revenue upon shipment to the
customer.

Research and development:  Research and development costs are charged to expense
as incurred.

Advertising:  Expenditures for advertising costs are expensed as
incurred.

Earnings (loss) per share: The Financial  Accounting  Standards Board has issued
Statement  No. 128,  Earnings Per Share,  which  supersedes  APB Opinion No. 15.
Statement  No.  128  requires  the  presentation  of  earnings  per share by all
entities  that have common stock or  potential  common  stock,  such as options,
warrants, and convertible securities, outstanding that trade in a public market.
Those entities that have only common stock  outstanding  are required to present
basic  earnings  per share  amounts.  Basic per share  amounts  are  computed by
dividing net income  (loss) (the  numerator) by the  weighted-average  number of
common shares outstanding (the denominator).  All other entities are required to
present basic and diluted per share  amounts.  Diluted per share amounts  assume
the conversion,  exercise, or issuance of all potential common stock instruments
unless the effect is to reduce the loss or increase  the income per common share
from continuing operations.

The Company  initially applied Statement No. 128 for the year ended December 31,
1997, and, as required by the statement,  has restated all per share information
for the prior years to conform to the statement.

The Company had  outstanding  options to purchase  701,333 and 517,167 shares of
common  stock at an average  price of $3.84 and $4.37 per share during the years
ended  December  31, 1997 and 1996,  respectively.  The Company also has 150,000
shares  of  convertible  preferred  stock  outstanding.  Those  options  and the
preferred  stock were not included in the  computation of diluted loss per share
in 1997 and 1996 as they would be antidilutive.

Of the 452,334  options  outstanding  at December  31,  1995, a total of 125,000
options to purchase common stock at an average price of $5.60 per share were not
included in the  computation  of diluted  income per share  because the exercise
price of those options exceeded the average market price of the common shares in
1995.

Realization  of  deferred  tax  assets  is  dependent  upon  the  generation  of
sufficient  future  taxable  income.  At  December  31,  1996,  the  Company had
established  a valuation  allowance  against a portion of the net  deferred  tax
assets in recognition of the risk that part of the loss  carryforward may not be
realized.  During 1997, management determined that sufficient uncertainty exists
regarding the  realizability of the deferred tax assets,  and  accordingly,  the
Company  increased the valuation  allowance to entirely reserve the net deferred
tax asset of the Company.

At  December  31,  1997,  the  Company's  net  operating  loss  carryforward  is
approximately $5,390,000 and expires as follows:



2011                  $       1,850,000
2012                          3,540,000


Note 5.  Preferred Stock

The preferred  shares are  convertible  at the rate of one share of common stock
for each share of preferred stock, subject to certain antidilution  adjustments.
Conversion  is  mandatory  in the event of certain  future  public  offerings of
corporate stock.  The holders of the preferred stock have certain  piggyback and
demand registration  rights,  have a liquidation  preference of $2.50 per share,
and share in dividends paid on common stock.

Note 6.  Stock Options

The Company has reserved  800,000 common shares for issuance under qualified and
nonqualified stock options for its key employees and directors.  The Company has
also reserved  50,000 common shares for issuance under  nonqualified  options to
various  distributors,  dealers,  and  consultants.  Option  prices are the fair
market  value of the stock at the time the option was  granted.  Options  become
exercisable  as  determined  at the date of grant by a committee of the Board of
Directors.  Options  expire ten years after the date of grant  unless an earlier
expiration date is set at the time of grant.

The Company has adopted the disclosure-only provisions of Statement of Financial
Accounting   Standards  No.  123,   Accounting  for  Stock-Based   Compensation.
Accordingly,  no  compensation  cost has been  recognized  for the stock  option
plans.  Had  compensation  cost  for  the  Company's  stock  option  plans  been
determined  based on the fair value at the grant date for awards in 1997,  1996,
and 1995  consistent  with the  provisions  of SFAS No. 123, the  Company's  net
income  (loss) and basic and diluted  income (loss) per share would have changed
to the pro forma amounts indicated below:



                                               Years Ended December 31
                                            1997            1996         1995

Net income (loss), as reported         $ (4,182,879)   $ (1,706,332)  $ 175,626

Net income (loss), pro forma             (4,391,620)     (1,844,604)    112,348

Basic and diluted income (loss), per
  share, as reported                          (1.45)          (0.60)       0.06

Basic and diluted income (loss), per
  share, pro forma                            (1.52)          (0.64)       0.04


The fair value of each option  grant is estimated on the date of grant using the
Black-Scholes   option-pricing   model  with  the   following   weighted-average
assumptions used for grants in 1997, 1996, and 1995:



                                             Years Ended December 31
                                             1997        1996        1995

Expected dividend yield                       --          --          --
Expected stock price volatility             53.26%      48.39%      32.76%
Risk-free interest rate                      6.17%       5.87%       6.71%
Expected life of options                   3.6 years   3 years     3 years
Weighted-average fair value of options
  granted during the year                  $ 1.39      $ 1.29      $ 1.15


The pro forma  effect on net loss or net income in 1997,  1996,  and 1995 is not
representative  of the pro forma effect in future years because it does not take
into consideration pro forma  compensation  expense related to grants made prior
to 1995.

Note 8.  Commitments and Contingencies

License  agreement:  In  December  1996,  the  Company  entered  into a  license
agreement  with a software  company to allow the Company to bundle the  licensed
products into certain of the Company's products.  Under the agreement,  payments
to the software  company for the licensed  products are based upon the number of
units sold and the nature of the  software  bundled.  In  addition,  the Company
agreed to purchase a minimum  quantity of software units over a specified period
of time.  The value of the minimum  purchase is included in the initial  license
agreement.

At December 31, 1996, the Company had paid $109,750 as the first payment for the
license  agreement,  with an additional  $768,250 to be paid in seven  quarterly
installments  pending the successful  delivery of a beta version of the licensed
product from the software company in 1997. Upon delivery of the product in 1997,
the Company  recorded an  additional  liability of $768,250 and a  corresponding
asset for prepaid license fees.  Subsequently,  the software  company  announced
that  certain of the  licensed  software  would be  available  at no cost to the
general  public.  As a result of this  announcement,  the Company has  suspended
payments, with $439,000 remaining under the original agreement,  and the Company
is seeking to  renegotiate  the  agreement to reduce or eliminate  the remaining
liability.  Upon completion of any contract  amendment,  the prepaid license fee
and corresponding liability would be adjusted to reflect the new agreement.

Leases:   The  Company  leases  its  office  and  warehouse   facilities   under
noncancelable operating leases which expire in May and June 1999. Minimum annual
cash  commitments  under this lease are  approximately  $156,000 and $75,000 for
1998 and 1999,  respectively.  Total rent  expense  under these  leases  totaled
$136,000 in 1997 and $97,000 in 1996 and 1995.

Note 9.  Subsequent Event

In January 1998,  the Company  obtained a $1,000,000  line of credit from a bank
which  bears  interest  at 1.25  percent  above the prime rate and is secured by
substantially all assets of the Company.  The line of credit expires in May 1998
and is subject to annual renewal.

                              EMPLOYMENT AGREEMENT


         This  Employment  Agreement  made and entered into  effective as of the

2.       Term of Employment

                  (i)      Mutual  written   agreement   between  the  Board  of
                           Directors of Datakey and  Executive to terminate  his

                  (iii)    Executive's   disability  defined  as  physically  or

                           Engineering for a period of six  consecutive  months;

shall not be eligible to receive any severance benefits. The date of termination
under this Section 7 shall be on the day the notice of termination  for cause is

<PAGE>

8.       Payment Upon Termination of Employment Without Cause

         a. If during the term of this Agreement Executive is terminated without
cause,  and without cause shall include death,  disability or mutual  agreement,
Executive  shall not be  entitled  to receive  his agreed  compensation  for the
balance of the term of this  Agreement  but shall  instead  receive a  severance
payment  equal  to his base  monthly  compensation  payable  for six  months  in
accordance with Datakey's payment periods beginning on the 10th day of the first
month following the last month of his employment term.

         b. Base  compensation  shall be deemed to be no less than $7,500.00 per

         d. The Company will  continue to provide  medical and health  coverage,
under its plans as they currently exist or may hereafter be amended,  at Company
subsidized  rates  during  the  six-month  severance  pay  period.   Thereafter,
Executive  and his  covered  dependents  will be  entitled  to elect to continue
coverage  under COBRA to the extent it is available.  Coverage by the Company or
under COBRA will end on the earlier of  Executive's  obtaining  new  employment,
which gives him the ability to provide medical and health insurance coverage for
himself  and his family  through  his new  employer,  or the  failure to pay any
premium when due.

of the first month following the last month of the Employment Term in accordance
with Datakey's payment periods.

         b. The payments  provided for under this Section 9 shall,  in the event
of Executive's death,  continue and shall be payable to his wife if she survives
or, if not, to his estate.

         c. The Company will  continue to provide  medical and health  coverage,
under its plans as they currently exist or may hereafter be amended,  at Company
subsidized  rates  during  the  six-month  severance  pay  period.   Thereafter,
Executive  and his  covered  dependents  will be  entitled  to elect to continue
coverage  under COBRA to the extent it is available.  Coverage by the Company or
under COBRA will end on the earlier of  Executive's  obtaining  new  employment,
which gives him the ability to provide medical and health insurance coverage for
himself  and his family  through  his new  employer,  or the  failure to pay any
premium when due.

10.      Termination of Employment or Resignation  Within Six Months of a Change
         in Control

         a. If Employee's employment is terminated within six months of a Change
of  Control,  or if  Employee  resigns  within six months of a Change of Control
because of a diminution of either  position  responsibilities  or  remuneration,
notwithstanding such termination or resignation, Employee shall receive his base
monthly compensation for a period of six months. The severance payments shall be
made in six monthly  installments  beginning  on the 10th day of the first month
following Employee's termination or resignation in accordance with the Company's
payroll periods.

         b. A Change in  Control  shall be deemed to have  occurred  if: (a) any
person or entity  becomes the beneficial  owner of thirty-five  percent (35%) or
more  of the  Company's  outstanding  securities  other  than  any  institution,
individual,  individuals acting in concert, or entity owning thirty-five percent
(35%) or more of the  Company's  outstanding  securities  as of the date of this
Agreement; (b) the consummation of a merger or consolidation of the Company into
or with  any  other  corporation;  (c) the  consummation  of a plan of  complete
liquidation of the Company; or (d) the consummation of the sale of substantially
all of the Company's assets.

         c. The payments  provided for under this Section 10 shall, in the event
of Employee's death,  continue and be payable to his wife if she survives or, if
not, to his estate.

11.      Nondisclosure

         Except by  written  permission  from  Datakey,  Executive  shall  never
disclose or use any trade secrets,  sales  projections,  formulations,  customer
lists or information, product specifications or information, credit information,
production  know-how,  research and development  plans or other  information not
generally known to the public ("Confidential  Information")  acquired or learned
by Executive during the course,  and on account,  of his employment,  whether or
not developed by Executive,  except as such disclosure or use may be required by
his duties to Datakey,  and then only in strict  accordance with his obligations
of service and loyalty thereto. Upon termination of employment, Executive agrees
to deliver to Datakey all Confidential Information.

12.      Inventions

         Any invention,  discovery,  improvement, or idea, whether patentable or
copyrightable  or not,  and  whether  or not shown or  described  in  writing or
reduced to practice  ("Invention")  shall be  promptly  and fully  disclosed  by
Executive to the Company,  and the Company will hold in trust for its sole right
and benefit, any Invention that Executive,  during the period of employment, and
for one year thereafter,  make,  conceive,  or reduce to practice or cause to be
made,  conceived,  or reduced to practice,  either alone or in conjunction  with
others, that:

                  a. Relates to any subject  matter  pertaining  to  Executive's
         employment with the Company;


<PAGE>

                  b. Relates to or is directly or indirectly  connected with the
         Company's business, products, projects, or Confidential Information; or

                  c. Involves the use of any time, material,  or facility of the
         Company's.

Executive hereby assigns to the Company all of his right, title, and interest in
and to all such  Inventions  and, upon the  Company's  request,  shall  execute,
verify, and deliver to the Company such documents including, without limitation,
assignments and  applications  for Letters Patent,  and shall perform such other
acts,  including,  without  limitation,  appearing  as a witness  in any  action
brought in connection with this Employment Agreement that is necessary to enable
the Company to obtain the sole right, title, and benefit to all such Inventions.

13.      Specific Performance

         Executive acknowledges that a breach of this Employment Agreement would
cause  Datakey  irreparable  injury and damage  which  could not be  remedied or
adequately compensated by damages at law; therefore,  Executive expressly agrees
that  Datakey  shall be  entitled,  in  addition to any other  remedies  legally
available,  to injunctive  and/or other equitable  relief to prevent a breach of
this Employment Agreement.

14.      Noncompetition

         a. For a period of six months from and after the end of the  Employment
Term or any extension thereof or after termination of employment, Executive will
not, directly or indirectly, alone or in any capacity with another legal entity,
(i) engage in any  activity  that  competes in any respect  with  Datakey,  (ii)
contact or in any way interfere or attempt to interfere with the relationship of
Datakey with any current or potential  customers of Datakey,  or (iii) employ or
attempt to employ any employee of Datakey (other than a former employee  thereof
after such employee has terminated employment with the Datakey), and

         b. Executive  acknowledges that Datakey markets products throughout the
United States and that Datakey would be harmed if Executive conducted any of the
activities  described  in  this  Section  14  anywhere  in  the  United  States.
Therefore,  Executive  agrees that the  covenants  contained  in this Section 14
shall apply to all portions of, and throughout, the United States.

         c. Executive  acknowledges  that if he fails to fulfill his obligations
under this  Section  14,  the  damages to  Datakey  would be very  difficult  to
determine.  Therefore,  in addition to any other rights or remedies available to
Datakey at law,  in equity,  or by  statute,  Executive  hereby  consents to the
specific  enforcement of the provisions of this Section 14 by Datakey through an
injunction or restraining order issued by the appropriate court.


<PAGE>

         d. To the extent any  provision  of this Section 14 shall be invalid or
unenforceable, it shall be considered deleted herefrom and the remainder of such
provision  and this Section 14 shall be  unaffected  and shall  continue in full
force and effect.  In  furtherance  to and not in limitation  of the  foregoing,
should the duration or geographical  extent of, or business  activities  covered
by,  any  provision  of this  Section 14 be in excess of that which is valid and
enforceable  under  applicable  law, then such  provision  shall be construed to
cover only that duration, extent or activities which are validly and enforceably
covered.  Executive  acknowledges the uncertainty of the law in this respect and
expressly  stipulates  that  this  Section  14 be given the  construction  which
renders  its  provisions  valid  and  enforceable  to the  maximum  extent  (not
exceeding its expressed terms) possible under applicable laws.

15.      Miscellaneous

         a. Waiver by Datakey of a breach of any provision of this  Agreement by
Executive shall not operate or be construed as a waiver of any subsequent breach
by Executive.

         b. This  Agreement  shall be binding  upon and inure to the  benefit of
Datakey,  its successors and assigns, and as to Executive,  his heirs,  personal
representatives, estate, legatees, and assigns.

         c. This Agreement  constitutes the entire agreement between the parties
hereto  with  respect to the  subject  matter  hereof and  supersedes  all prior
agreements whether written or oral relating hereto.

         d. This Agreement  shall be governed by and construed under the laws of
the State of Minnesota.


         IN WITNESS  WHEREOF,  the parties have hereto  executed this Employment
Agreement effective as of the day and year first above written.

         The  purpose of the Plan is to promote  the  success of the Company and

approval by the  shareholders of the Company within twelve (12) months before or

                             EFFECTIVE DATE OF PLAN

<PAGE>

                                   SECTION 4.

                                 ADMINISTRATION

         The Plan shall be administered by the Board of Directors of the Company
(hereinafter  referred  to as  the  "Board")  or by a  Committee  which  may  be
appointed  by the  Board  from  time to time  (collectively  referred  to as the
"Administrator").  The  Administrator  shall have all of the powers vested in it
under the  provisions  of the  Plan,  including  but not  limited  to  exclusive
authority  (where  applicable and within the  limitations  described  herein) to
determine,  in its  sole  discretion,  whether  an  incentive  stock  option  or
nonqualified  stock option shall be granted,  the  individuals  to whom, and the
time or times at which,  options shall be granted,  the number of shares subject
to each option and the option price and terms and conditions of each option. The
Administrator  shall have full power and authority to  administer  and interpret
the Plan, to make and amend rules,  regulations and guidelines for administering
the Plan, to prescribe the form and  conditions of the  respective  stock option
agreements (which may vary from Optionee to Optionee) evidencing each option and
to make all other  determinations  necessary or advisable for the administration
of the Plan.  The  Administrator's  interpretation  of the Plan, and all actions
taken and determinations made by the Administrator  pursuant to the power vested
in it hereunder, shall be conclusive and binding on all parties concerned.

         No member of the Board or the Committee  shall be liable for any action
taken or determination  made in good faith in connection with the administration
of the Plan. In the event the Board appoints a Committee as provided  hereunder,
any action of the Committee with respect to the administration of the Plan shall
be taken pursuant to a majority vote of the Committee members or pursuant to the
written resolution of all Committee members.


                                   SECTION 5.

                                  PARTICIPANTS

         The  Administrator  shall  from  time to time,  at its  discretion  and
without  approval of the  shareholders,  designate  those  employees,  officers,
directors (including Non-Employee Directors),  consultants,  and advisors of the
Company or of any Subsidiary to whom nonqualified stock options shall be granted
under this Plan;  provided,  however,  that consultants or advisors shall not be
eligible to receive stock options  hereunder  unless such  consultant or advisor
renders bona fide  services to the Company or  Subsidiary  and such services are
not in  connection  with the offer or sale of  securities  in a capital  raising
transaction;  and, provided further, that Non-Employee Directors will be granted
options   pursuant  to  Section  11  hereof   without   further  action  by  the
Administrator. The Administrator shall, from time to time, at its discretion and
without approval of the  shareholders,  designate those employees of the Company
or any  Subsidiary to whom  incentive  stock options shall be granted under this
Plan.  The  Administrator  may  grant  additional  incentive  stock  options  or
nonqualified  stock  options  under this Plan to some or all  participants  then
holding options or may grant options solely or partially to new participants. In
designating  participants,  the Administrator shall also determine the number of
shares to be optioned to each such participant.  The Board may from time to time
designate individuals as being ineligible to participate in the Plan.

                                   SECTION 6.

                                      STOCK

         The Stock to be optioned  under this Plan shall  consist of  authorized
but unissued shares of Option Stock.  Five Hundred Thousand  (500,000) shares of
Option  Stock  shall be  reserved  and  available  for  options  under the Plan;
provided,  however, that the total number of shares of Option Stock reserved for
options under this Plan shall be subject to adjustment as provided in Section 13
of the Plan.  In the event that any  outstanding  option  under the Plan for any
reason  expires or is terminated  prior to the exercise  thereof,  the shares of
Option Stock allocable to the unexercised  portion of such option shall continue
to be reserved for options under the Plan and may be optioned hereunder.


                                   SECTION 7.

                                DURATION OF PLAN

         Incentive  stock options may be granted  pursuant to the Plan from time
to time during a period of ten (10) years from the effective  date as defined in
Section 3.  Nonqualified  stock options may be granted pursuant to the Plan from
time to time  after  the  effective  date of the  Plan  and  until  the  Plan is
discontinued  or terminated by the Board.  Any  incentive  stock option  granted
during such ten-year period and any  nonqualified  stock option granted prior to
the  termination  of the Plan by the Board shall remain in full force and effect
until the  expiration  of the option as  specified  in the written  stock option
agreement and shall remain subject to the terms and conditions of this Plan.


                                   SECTION 8.

                                     PAYMENT

         Optionees may pay for shares upon exercise of options granted  pursuant
to this Plan with cash,  personal check,  certified check or, if approved by the
Administrator in its sole discretion, Common Stock of the Company valued at such
Stock's  then  Fair  Market  Value,  or such  other  form of  payment  as may be
authorized by the Administrator.  The Administrator may, in its sole discretion,
limit the forms of payment  available  to the  Optionee  and may  exercise  such
discretion  any time  prior to the  termination  of the  option  granted  to the
Optionee or upon any exercise of the option by the Optionee.

         With respect to payment in the form of Common Stock of the Company, the
Administrator  may  require  advance  approval  or adopt  such rules as it deems
necessary to assure compliance with Rule 16b-3, or any successor  provision,  as
then in  effect,  of the  General  Rules and  Regulations  under the  Securities
Exchange Act of 1934, if applicable.

                                   SECTION 9.

                 TERMS AND CONDITIONS OF INCENTIVE STOCK OPTIONS

         Each incentive stock option granted pursuant to this Section 9 shall be
evidenced by a written  stock option  agreement  (the "Option  Agreement").  The
Option  Agreement  shall be in such form as may be approved from time to time by
the  Administrator  and may vary from Optionee to Optionee;  provided,  however,
that each Optionee and each Option Agreement shall comply with and be subject to
the following terms and conditions:

         (a) Number of Shares and Option Price. The Option Agreement shall state
         the total number of shares  covered by the incentive  stock option.  To
         the extent  required to qualify the Option as an incentive stock option
         under  Section  422 of the  Internal  Revenue  Code,  or any  successor
         provision,  the  option  price  per  share  shall  not be less than one
         hundred percent (100%) of the Fair Market Value of the Common Stock per
         share  on the date  the  Administrator  grants  the  option;  provided,
         however,  that if an  Optionee  owns  stock  possessing  more  than ten
         percent  (10%) of the total  combined  voting  power of all  classes of
         stock of the  Company  or of its Parent or any  Subsidiary,  the option
         price per share of an incentive  stock option  granted to such Optionee
         shall  not be less  than one  hundred  ten  percent  (110%) of the Fair
         Market  Value of the Common Stock per share on the date of the grant of
         the option. The Administrator  shall have full authority and discretion
         in  establishing  the option  price and shall be fully  protected in so
         doing.

         (b) Term and  Exercisability of Incentive Stock Option. The term during
         which  any  incentive  stock  option  granted  under  the  Plan  may be
         exercised  shall be established in each case by the  Administrator.  To
         the extent  required to qualify the Option as an incentive stock option
         under  Section  422 of the  Internal  Revenue  Code,  or any  successor
         provision,  in no event shall any incentive stock option be exercisable
         during a term of more than ten (10) years after the date on which it is
         granted;  provided,  however, that if an Optionee owns stock possessing
         more than ten percent (10%) of the total  combined  voting power of all
         classes of stock of the Company or of its parent or any Subsidiary, the
         incentive  stock option  granted to such Optionee  shall be exercisable
         during a term of not more than  five (5) years  after the date on which
         it is granted.

         The Option  Agreement  shall  state  when the  incentive  stock  option
         becomes  exercisable and shall also state the maximum term during which
         the option may be exercised.  In the event an incentive stock option is
         exercisable  immediately,  the manner of  exercise of the option in the
         event it is not exercised in full immediately shall be specified in the
         Option Agreement.  The Administrator may accelerate the  exercisability
         of  any  incentive   stock  option  granted   hereunder  which  is  not
         immediately exercisable as of the date of grant.


<PAGE>

         (c) Other  Provisions.  The  Option  Agreement  authorized  under  this
         Section 9 shall  contain  such other  provisions  as the  Administrator
         shall deem  advisable.  Any such Option  Agreement  shall  contain such
         limitations and  restrictions  upon the exercise of the option as shall
         be  necessary  to  ensure  that  such  option  will  be  considered  an
         "incentive  stock  option" as defined  in Section  422 of the  Internal
         Revenue Code or to conform to any change therein.

                                   SECTION 10.

               TERMS AND CONDITIONS OF NONQUALIFIED STOCK OPTIONS

         Each  nonqualified  stock  option  granted  pursuant to this Section 10
shall be evidenced by a written Option Agreement.  The Option Agreement shall be
in such form as may be approved from time to time by the  Administrator  and may
vary from Optionee to Optionee;  provided,  however, that each Optionee and each
Option  Agreement  shall comply with and be subject to the  following  terms and
conditions:

         (a) Number of Shares and Option Price. The Option Agreement shall state
         the total number of shares  covered by the  nonqualified  stock option.
         Unless otherwise determined by the Administrator,  the option price per
         share shall be one hundred  percent  (100%) of the Fair Market Value of
         the  Common  Stock per share on the date the  Administrator  grants the
         option.

         (b) Term and  Exercisability  of  Nonqualified  Stock Option.  The term
         during which any  nonqualified  stock option granted under the Plan may
         be exercised  shall be established  in each case by the  Administrator.
         The Option  Agreement  shall state when the  nonqualified  stock option
         becomes  exercisable and shall also state the maximum term during which
         the option may be exercised.  In the event a nonqualified  stock option
         is exercisable immediately, the manner of exercise of the option in the
         event it is not exercised in full immediately shall be specified in the
         stock  option   agreement.   The   Administrator   may  accelerate  the
         exercisability of any nonqualified stock option granted hereunder which
         is not immediately exercisable as of the date of grant.

         (c)  Withholding.  The Company or its  Subsidiary  shall be entitled to
         withhold  and deduct  from  future  wages of the  Optionee  all legally
         required  amounts  necessary  to satisfy  any and all  withholding  and
         employment-related  taxes attributable to the Optionee's  exercise of a
         nonqualified  stock option. In the event the Optionee is required under
         the  Option  Agreement  to  pay  the  Company,   or  make  arrangements
         satisfactory to the Company respecting payment of, such withholding and
         employment-related  taxes, the Administrator may, in its discretion and
         pursuant to such rules as it may adopt,  permit the Optionee to satisfy
         such  obligation,  in whole or in part, by electing to have the Company
         withhold shares of Common Stock otherwise issuable to the Optionee as a
         result of the  option's  exercise  equal to the amount  required  to be
         withheld for tax purposes.  Any stock  elected to be withheld  shall be
         valued at its Fair Market Value, as of the date the amount of tax to be
         withheld  is  determined  under  applicable  tax  law.  The  Optionee's
         election to have shares  withheld for this purpose  shall be made on or
         before the date the option is exercised or, if later, the date that the
         amount of tax to be withheld is determined  under  applicable  tax law.
         Such  election  shall be approved by the  Administrator  and  otherwise
         comply  with  such  rules as the  Administrator  may  adopt  to  assure
         compliance  with Rule 16b-3,  or any  successor  provision,  as then in
         effect,  of the  General  Rules and  Regulations  under the  Securities
         Exchange Act of 1934, if applicable.


<PAGE>

         (d) Other  Provisions.  The  Option  Agreement  authorized  under  this
         Section 10 shall  contain such other  provisions  as the  Administrator
         shall deem advisable.


                                   SECTION 11.

                  GRANTING OF OPTIONS TO NON-EMPLOYEE DIRECTORS

         (a) Upon Joining Board. Each Non-Employee Director of the Company whose
         initial  election or appointment to the Board of Directors occurs on or
         after the date  this Plan is  approved  by the  Company's  shareholders
         shall,  as of the date of such  election,  automatically  be granted an
         option to purchase 15,000 shares of the Common Stock at an option price
         per share equal to 100% of the Fair Market Value of the Common Stock on
         such date.  Options  granted  pursuant to this  subsection (a) shall be
         immediately  exercisable  to the extent of 3,000 shares subject to such
         option and to the extent of an  additional  3,000 shares on each of the
         first, second, third and fourth anniversaries of the date of grant.

         (b) Upon Re-election to Board. Each  Non-Employee  Director who, on and
         after the date this Plan is approved by the Company's shareholders,  is
         re-elected  as a  director  of the  Company  or  whose  term of  office
         continues  after a  meeting  of  shareholders  at which  directors  are
         elected  shall,  as of the  date of  such  re-election  or  shareholder
         meeting, automatically be granted an option to purchase 2,500 shares of
         the Common Stock at an option price per share equal to 100% of the Fair
         Market  Value of the Common  Stock on the date of such  re-election  or
         shareholder  meeting.  Options granted  pursuant to this subsection (b)
         shall be immediately exercisable in full.

         (c) General. No director shall receive more than one option pursuant to
         subsection  (b) of this Section 11 in any one fiscal year.  All options
         granted pursuant to this Section 11 shall be designated as nonqualified
         options  and shall be subject to the same terms and  provisions  as are
         then in effect  with  respect to granting  of  nonqualified  options to
         officers  and  employees of the  Company,  including  Section 13 of the
         Plan,  except that the option  shall expire on the earlier of (i) three
         months after the Optionee ceases to be a director (except by death) and
         (ii) ten  (10)  years  after  the date of  grant.  Notwithstanding  the
         foregoing,  in the event of the death of a Non-Employee  Director,  any
         option granted to such  Non-Employee  Director pursuant to this Section
         11 may be  exercised at any time within six months of the death of such
         Non-Employee  Director or on the date on which the option, by its terms
         expires, whichever is earlier.

                                   SECTION 12.

                               TRANSFER OF OPTION

         No incentive stock option shall be  transferable,  in whole or in part,
by the  Optionee  other than by will or by the laws of descent and  distribution
and,  during the  Optionee's  lifetime,  the option may be exercised only by the
Optionee.  If the Optionee  shall  attempt any transfer of any  incentive  stock
option  granted  under the Plan during the  Optionee's  lifetime,  such transfer
shall be void and the incentive stock option, to the extent not fully exercised,
shall terminate.

         The Administrator  may, in its sole discretion,  permit the Optionee to
transfer any or all  nonqualified  stock options to any member of the Optionee's
"immediate  family" as such term is defined in Rule 16a-1(e)  promulgated  under
the Securities  Exchange Act of 1934, or any successor  provision,  or to one or
more  trusts  whose  beneficiaries  are  members of such  Optionee's  "immediate
family" or  partnerships  in which such family  members  are the only  partners;
provided,  however, that the Optionee receives no consideration for the transfer
and such transferred  nonqualified  stock option shall continue to be subject to
the same terms and  conditions  as were  applicable to such  nonqualified  stock
option immediately prior to its transfer.


                                   SECTION 13.

                    RECAPITALIZATION, SALE, MERGER, EXCHANGE
                                 OR LIQUIDATION

         In the event of an  increase  or  decrease  in the  number of shares of
Common Stock  resulting  from a subdivision  or  consolidation  of shares or the
payment of a stock  dividend or any other  increase or decrease in the number of
shares of Common Stock effected without receipt of consideration by the Company,
the number of shares of Option  Stock  reserved  under  Section 6 hereof and the
number of shares of Option  Stock  covered  by each  outstanding  option and the
price per share  thereof  shall be adjusted by the Board to reflect such change.
Additional  shares which may be credited  pursuant to such  adjustment  shall be
subject to the same restrictions as are applicable to the shares with respect to
which the adjustment relates.

         Unless otherwise  provided in the stock option agreement,  in the event
of

         (i)      an acquisition  of the Company by a corporation,  partnership,
                  trust or other entity not  controlled  by the Company  through
                  (A) the sale of substantially  all of the Company's assets and
                  the consequent discontinuance of its business or (B) through a
                  merger,     consolidation,      exchange,      reorganization,
                  reclassification,   extraordinary  dividend,   divestiture  or
                  liquidation   of  the   Company,   other   than  a  merger  or
                  consolidation  which 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  combined   voting  power  of  the  voting
                  securities of the Company or such surviving entity outstanding
                  immediately  after such merger or consolidation  (collectively
                  referred to as a "transaction"), or


<PAGE>

         (ii)     a change of control such that (A) any individual, partnership,
                  trust or other entity  becomes after the effective date of the
                  Plan the  "beneficial  owner" (as  defined in Rule 13d-3 under
                  the Exchange Act),  directly or indirectly,  of 30% or more of
                  the  combined  voting  power  of  the  Company's   outstanding
                  securities ordinarily having the right to vote at elections of
                  directors of the Company,  or (B)  individuals  who constitute
                  the Board of Directors of the Company on the effective date of
                  the  Plan  cease  for any  reason  to  constitute  at  least a
                  majority thereof, provided that any person becoming a director
                  subsequent to the effective  date of the Plan whose  election,
                  or nomination for election by the Company's shareholders,  was
                  approved  by a vote of at least a  majority  of the  directors
                  comprising  the  Board  of  Directors  of the  Company  on the
                  effective  date of the Plan  (either by a specific  vote or by
                  approval of the proxy  statement  of the Company in which such
                  person is named as a nominee for director,  without  objection
                  to such nomination)  shall be, for purposes of this clause (B)
                  considered as though such person were a member of the Board of
                  Directors  of the  Company on the  effective  date of the Plan
                  (collectively referred to as a "change of control"),

all outstanding  options shall become  immediately  exercisable,  whether or not
such  options  had  become  exercisable  prior to the  transaction  or change of
control;  provided,  however,  that if the  acquiring  party  seeks  to have the
transaction  accounted for on a "pooling of interests" basis and, in the opinion
of the Company's  independent  certified  public  accountants,  accelerating the
exercisability  of such  options  would  preclude a pooling of  interests  under
generally  accepted  accounting  principles,  the exercisability of such options
shall not  accelerate.  In  addition  to the  foregoing,  in the event of such a
transaction  or change of control,  the Board may provide for one or more of the
following:

         (a)  the  complete   termination  of  this  Plan  and  cancellation  of
         outstanding  options not  exercised  prior to a date  specified  by the
         Board (which date shall give  Optionees a reasonable  period of time in
         which  to  exercise  the  options  prior to the  effectiveness  of such
         transaction);

         (b)  that  Optionees  holding  outstanding  incentive  or  nonqualified
         options  shall  receive,  with  respect to each  share of Option  Stock
         subject  to  such  options,  as of  the  effective  date  of  any  such
         transaction,  cash in an amount  equal to the excess of the Fair Market
         Value  of such  Option  Stock  on the date  immediately  preceding  the
         effective date of such  transaction  over the option price per share of
         such  options;  provided  that  the  Board  may,  in lieu of such  cash
         payment, distribute to such Optionees shares of stock of the Company or
         shares of stock of any corporation  succeeding the Company by reason of
         such transaction,  such shares having a value equal to the cash payment
         herein; or

         (c) the continuance of the Plan with respect to the exercise of options
         which were  outstanding as of the date of adoption by the Board of such
         plan for such transaction and provide to Optionees holding such options
         the right to  exercise  their  respective  options as to an  equivalent
         number of shares of stock of the corporation  succeeding the Company by
         reason of such transaction.


<PAGE>

The Board may restrict the rights of or the  applicability of this Section 13 to
the extent necessary to comply with Section 16(b) of the Securities Exchange Act
of 1934,  the Internal  Revenue Code or any other  applicable law or regulation.
The grant of an option pursuant to the Plan shall not limit in any way the right
or power of the Company to make adjustments, reclassifications,  reorganizations
or changes  of its  capital  or  business  structure  or to merge,  exchange  or
consolidate or to dissolve,  liquidate,  sell or transfer all or any part of its
business or assets.


                                   SECTION 14.

                            SECURITIES LAW COMPLIANCE

         No shares of Common  Stock shall be issued  pursuant to the Plan unless
and until there has been compliance,  in the opinion of Company's counsel,  with
all applicable legal requirements,  including without limitation, those relating
to securities laws and stock exchange  listing  requirements.  As a condition to
the issuance of Option Stock to Optionee, the Administrator may require Optionee
to (i)  represent  that the  shares of  Option  Stock  are  being  acquired  for
investment  and  not  resale  and to  make  such  other  representations  as the
Administrator shall deem necessary or appropriate to qualify the issuance of the
shares  as  exempt  from the  Securities  Act of 1933 and any  other  applicable
securities  laws,  and (ii)  represent  that  Optionee  shall not dispose of the
shares of Option Stock in violation of the  Securities  Act of 1933 or any other
applicable securities laws.

         As a further  condition to the grant of any  incentive or  nonqualified
stock option or the issuance of Option Stock to Optionee, Optionee agrees to the
following:

         (a) In the  event  the  Company  advises  Optionee  that  it  plans  an
         underwritten public offering of its Common Stock in compliance with the
         Securities  Act of 1933,  as amended,  and the  underwriter(s)  seek to
         impose  restrictions  under which certain  shareholders may not sell or
         contract  to sell or grant any  option to buy or  otherwise  dispose of
         part or all of their stock  purchase  rights of the  underlying  Common
         Stock,  Optionee will not, for a period not to exceed 180 days from the
         prospectus,  sell or  contract  to sell or  grant an  option  to buy or
         otherwise dispose of any incentive or nonqualified stock option granted
         to  Optionee  pursuant to the Plan or any of the  underlying  shares of
         Common Stock without the prior written consent of the underwriter(s) or
         its representative(s).

         (b)  In  the  event  the  Company  makes  any  public  offering  of its
         securities and determines in its sole  discretion  that it is necessary
         to reduce the number of issued but unexercised stock purchase rights so
         as to comply  with any states  securities  or Blue Sky law  limitations
         with respect thereto,  the Board of Directors of the Company shall have
         the right (i) to  accelerate  the  exercisability  of any  incentive or
         nonqualified  stock  option and the date on which such  option  must be
         exercised,  provided  that the Company  gives  Optionee  prior  written
         notice of such acceleration, and (ii) to cancel any options or portions
         thereof which Optionee does not exercise prior to or  contemporaneously
         with such public offering.


<PAGE>

         (c) In the event of a  transaction  (as  defined  in  Section 13 of the
         Plan)  which is treated as a "pooling  of  interests"  under  generally
         accepted accounting  principles,  Optionee will comply with Rule 145 of
         the  Securities  Act of 1933 and any other  restrictions  imposed under
         other  applicable  legal or  accounting  principles  if  Optionee is an
         "affiliate"  (as  defined  in  such  applicable  legal  and  accounting
         principles) at the time of the  transaction,  and Optionee will execute
         any documents necessary to ensure compliance with such rules.

         The  Company  reserves  the  right  to  place  a  legend  on any  stock
certificate  issued upon exercise of an option  granted  pursuant to the Plan to
assure compliance with this Section 14.


                                   SECTION 15.

                             RIGHTS AS A SHAREHOLDER

         An Optionee (or the Optionee's  successor or successors)  shall have no
rights as a  shareholder  with respect to any shares  covered by an option until
the date of the  issuance of a stock  certificate  evidencing  such  shares.  No
adjustment shall be made for dividends  (ordinary or  extraordinary,  whether in
cash, securities or other property), distributions or other rights for which the
record  date is prior to the date such  stock  certificate  is  actually  issued
(except as otherwise provided in Section 13 of the Plan).


                                   SECTION 16.

                              AMENDMENT OF THE PLAN

         The Board may from time to time,  insofar as permitted by law,  suspend
or discontinue the Plan or revise or amend it in any respect; provided, however,
that no such revision or amendment, except as is authorized in Section 13, shall
impair the terms and  conditions of any option which is  outstanding on the date
of such revision or amendment to the material  detriment of the Optionee without
the consent of the Optionee.  Notwithstanding the foregoing, no such revision or
amendment shall (i) materially increase the number of shares subject to the Plan
except as provided  in Section 13 hereof,  (ii)  change the  designation  of the
class of  employees  eligible to receive  options,  (iii)  decrease the price at
which options may be granted,  or (iv) materially increase the benefits accruing
to  Optionees  under the Plan without the  approval of the  shareholders  of the
Company if such approval is required for compliance with the requirements of any
applicable  law or  regulation.  Furthermore,  the  Plan may  not,  without  the
approval of the shareholders, be amended in any manner that will cause incentive
stock  options to fail to meet the  requirements  of Section 422 of the Internal
Revenue Code.


                                   SECTION 17.

                        NO OBLIGATION TO EXERCISE OPTION

         The granting of an option shall impose no obligation  upon the Optionee
to exercise such option.  Further, the granting of an option hereunder shall not
impose upon the Company or any  Subsidiary any obligation to retain the Optionee
in its employ for any period.



                                  DATAKEY, INC.

                        INCENTIVE STOCK OPTION AGREEMENT


         THIS AGREEMENT, made effective as of this _____ day of _______________,
199___, by and between DATAKEY,  INC., a Minnesota  corporation (the "Company"),
and __________________ ("Optionee").

                                                W I T N E S S E T H:

         WHEREAS,  Optionee on the date hereof is a key  employee of the Company
or one of its Subsidiaries; and

         WHEREAS,  the  Company  wishes to grant an  incentive  stock  option to
Optionee  to  purchase  shares of the  Company's  Common  Stock  pursuant to the
Company's 1997 Stock Option Plan (the "Plan"); and

         WHEREAS,  the  Administrator of the Plan has authorized the grant of an
incentive stock option to Optionee and has determined  that, as of the effective
date of this Agreement,  the fair market value of the Company's  Common Stock is
$_______ per share;

         NOW,  THEREFORE,  in  consideration  of the  premises and of the mutual
covenants herein contained, the parties hereto agree as follows:

         1. Grant of Option.  The Company  hereby grants to Optionee on the date
set forth above (the "Date of Grant"),  the right and option (the  "Option")  to
purchase  all or  portions of an  aggregate  of  _____________________  (______)
shares  of  Common  Stock at a per  share  price of  $________  on the terms and
conditions set forth herein, subject to adjustment pursuant to Section 13 of the
Plan. Except as otherwise provided in Paragraph 2(c), this Option is intended to
be an incentive stock option within the meaning of Section 422, or any successor
provision,  of the Internal  Revenue Code of 1986, as amended (the "Code"),  and
the regulations thereunder.

         2. Duration and Exercisability.

                  a. The term during  which this Option may be  exercised  shall
terminate  at the close of  business on  ________,  20___,  except as  otherwise
provided in  Paragraphs  2(b)  through  2(e) below.  This  Option  shall  become
exercisable according to the following schedule:


Vesting Date                  Percentage/Number of Shares






<PAGE>

Once the Option becomes  exercisable to the extent of one hundred percent (100%)
of the  aggregate  number of shares  specified  in  Paragraph  1,  Optionee  may
continue  to  exercise  this  Option  under  the terms  and  conditions  of this
Agreement  until the termination of the Option as provided  herein.  If Optionee
does not  purchase  upon an  exercise  of this  Option the full number of shares
which  Optionee is then  entitled to purchase,  Optionee  may purchase  upon any
subsequent   exercise  prior  to  this  Option's   termination  such  previously
unpurchased  shares in  addition  to those  Optionee  is  otherwise  entitled to
purchase.

                  b.  Termination  of Employment  (other than Change of Control,
Disability  or  Death).  If  Optionee's  employment  with  the  Company  or  any
Subsidiary is terminated for any reason other than because of a "transaction" or
"change of control" as described in Paragraph  2(c) or because of  disability or
death, this Option shall completely terminate on the earlier of (i) the close of
business on the three-month  anniversary date of such termination of employment,
and (ii) the expiration date of this Option stated in Paragraph 2 above.

                      In such period following  the  termination  of  Optionee's
employment,  this Option shall be exercisable  only to the extent the Option was
exercisable  on the vesting  date  immediately  preceding  such  termination  of
employment but had not previously been exercised.  To the extent this Option was
not  exercisable  upon such  termination  of  employment or if Optionee does not
exercise the Option within the time specified in this Paragraph 2(b), all rights
of Optionee under this Option shall be forfeited.

                  c. Change of Control.  If (i) Optionee's  employment  with the
Company or any Subsidiary is terminated because of a "transaction" or "change of
control  transaction"  (as those  terms are  defined in Section 13 of the Plan),
(ii) such  transaction  is treated as a "pooling of interests"  under  generally
accepted  accounting  principles,  and (iii)  Optionee is an  "affiliate" of the
Company or Subsidiary  under applicable  legal and accounting  principles,  this
Option shall  completely  terminate on the later of (A) the close of business on
the three-month  anniversary  date of such  termination of employment or (B) the
close of business on the date that is 60 days after the date on which affiliates
are no longer  restricted from selling,  transferring or otherwise  disposing of
the shares of stock received in the change of control transaction.

                      In such period following  the  termination  of  Optionee's
employment because of a "transaction" or "change of control",  this Option shall
become immediately  exercisable unless the acceleration of the exercisability of
this Option has been  prevented as provided in Section 13 of the Plan,  in which
case,  this  Option  shall be  exercisable  only to the  extent  the  Option was
exercisable  on the vesting  date  immediately  preceding  such  termination  of
employment, but had not previously been exercised. To the extent this Option was
not  exercisable  upon such  termination of employment,  or if Optionee does not
exercise the Option within the time specified in this Paragraph 2(c), all rights
of Optionee  under this Option shall be forfeited.  If Optionee  exercises  this
Option on a date that is after the three-month anniversary of the termination of
Optionee's  employment  or on a date that is more than ten years (or five years,
if applicable)  after the Date of Grant,  this Option shall not be treated as an
incentive stock option within the meaning of Code Section 422.


<PAGE>

                  d.  Disability.  If  Optionee  ceases to be an employee of the
Company or any  Subsidiary  due to  disability  (as such term is defined in Code
Section  22(e)(3),  or any successor  provision),  this Option shall  completely
terminate  on the  earlier  of (i) the  close of  business  on the  twelve-month
anniversary date of such termination of employment, and (ii) the expiration date
under this Option stated in Paragraph 2(a) above. In such period  following such
termination of employment,  this Option shall be exercisable  only to the extent
the Option was exercisable on the vesting date immediately preceding the date of
Optionee's  termination of employment.  If Optionee does not exercise the Option
within the time specified in this  Paragraph  2(d), all rights of Optionee under
this Option shall be forfeited.

                  e. Death. In the event of Optionee's  death, this Option shall
terminate  on the  earlier  of (i) the  close of  business  on the  twelve-month
anniversary  date of the date of Optionee's  death, and (ii) the expiration date
of this  Option  stated  in  Paragraph  2(a)  above.  In such  period  following
Optionee's  death,  this Option shall be exercisable by the person or persons to
whom Optionee's rights under this Option shall have passed by Optionee's will or
by the laws of  descent  and  distribution  only to the  extent  the  Option was
exercisable  on the vesting date  immediately  preceding  the date of Optionee's
death.  If such person or persons do not  exercise  this Option  within the time
specified  in this  Paragraph  2(e),  all  rights  under  this  Option  shall be
forfeited.

         3. Manner of Exercise.

                  a. General.  The Option may be exercised  only by Optionee (or
other  proper  party  in the  event  of death  or  incapacity),  subject  to the
conditions  of the Plan and  subject to such other  administrative  rules as the
Administrator may deem advisable, by delivering within the Option Period written
notice of exercise  to the Company at its  principal  office.  The notice  shall
state the number of shares as to which the Option is being  exercised  and shall
be accompanied by payment in full of the Option price for all shares  designated
in the notice. The exercise of the Option shall be deemed effective upon receipt
of such notice by the Company and upon payment that  complies  with the terms of
the Plan and this  Agreement.  The Option may be  exercised  with respect to any
number  or all of the  shares  as to  which  it can then be  exercised  and,  if
partially exercised, may be so exercised as to the unexercised shares any number
of times during the Option period as provided herein.

                  b. Form of  Payment.  Payment of the Option  price by Optionee
shall be in the form of cash,  personal  check,  certified  check or  previously
acquired shares of Common Stock of the Company, or any combination  thereof. Any
stock so  tendered  as part of such  payment  shall be valued at its Fair Market
Value as  provided in the Plan.  For  purposes  of this  Agreement,  "previously
acquired  shares of Common Stock" shall include  shares of Common Stock that are
already owned by Optionee at the time of exercise.

                  c. Stock Transfer  Records.  As soon as practicable  after the
effective exercise of all or any part of the Option,  Optionee shall be recorded
on the stock transfer books of the Company as the owner of the shares purchased,
and the  Company  shall  deliver  to  Optionee  one or more  duly  issued  stock
certificates evidencing such ownership. All requisite original issue or transfer
documentary stamp taxes shall be paid by the Company.


<PAGE>

         4. Miscellaneous.

                  a. Employment; Rights as Shareholder. This Agreement shall not
confer on Optionee any right with respect to  continuance  of  employment by the
Company or any of its  Subsidiaries,  nor will it  interfere in any way with the
right of the Company to terminate such employment. Optionee shall have no rights
as a shareholder with respect to shares subject to this Option until such shares
have been issued to Optionee upon exercise of this Option.  No adjustment  shall
be made for dividends (ordinary or extraordinary, whether in cash, securities or
other  property),  distributions  or other  rights for which the record  date is
prior to the date such  shares are  issued,  except as provided in Section 13 of
the Plan.

                  b. Securities Law Compliance. The exercise of all or any parts
of this Option  shall only be  effective  at such time as counsel to the Company
shall have determined that the issuance and delivery of Common Stock pursuant to
such  exercise  will not violate any state or federal  securities or other laws.
Optionee may be required by the Company,  as a condition of the effectiveness of
any  exercise of this  Option,  to agree in writing  that all Common Stock to be
acquired  pursuant  to such  exercise  shall be held,  until such time that such
Common  Stock is  registered  and freely  tradable  under  applicable  state and
federal  securities  laws,  for  Optionee's  own  account  without a view to any
further distribution  thereof,  that the certificates for such shares shall bear
an  appropriate  legend  to  that  effect  and  that  such  shares  will  not be
transferred  or  disposed  of except in  compliance  with  applicable  state and
federal securities laws.

                  c. Mergers, Recapitalizations, Stock Splits, Etc. Pursuant and
subject to Section 13 of the Plan, certain changes in the number or character of
the Common Stock of the Company (through sale, merger, consolidation,  exchange,
reorganization,     divestiture    (including    a    spin-off),    liquidation,
recapitalization,  stock split,  stock dividend or otherwise) shall result in an
adjustment,  reduction or enlargement, as appropriate, in Optionee's rights with
respect to any unexercised portion of the Option (i.e., Optionee shall have such
"anti-dilution"  rights under the Option with respect to such events,  but shall
not have "preemptive" rights).

                  d.  Withholding  Taxes on  Disqualifying  Disposition.  In the
event of a disqualifying disposition of the shares acquired through the exercise
of  this  Option,   Optionee  hereby  agrees  to  inform  the  Company  of  such
disposition.  Upon notice of a disqualifying  disposition,  the Company may take
such action as it deems  appropriate to insure that, if necessary to comply with
all applicable  federal or state income tax laws or regulations,  all applicable
federal and state  payroll,  income or other taxes are withheld from any amounts
payable by the Company to  Optionee.  If the Company is unable to withhold  such
federal and state taxes, for whatever  reason,  Optionee hereby agrees to pay to
the  Company an amount  equal to the  amount  the  Company  would  otherwise  be
required to withhold  under federal or state law.  Optionee may,  subject to the
approval and discretion of the Administrator or such administrative rules it may
deem  advisable,  elect  to  have  all or a  portion  of  such  tax  withholding
obligations  satisfied by delivering shares of the Company's Common Stock having
a fair market value equal to such obligations.


<PAGE>

                  e.  Nontransferability.  During the lifetime of Optionee,  the
accrued  Option  shall be  exercisable  only by  Optionee  or by the  Optionee's
guardian  or  other  legal  representative,  and  shall  not  be  assignable  or
transferable by Optionee, in whole or in part, other than by will or by the laws
of descent and distribution.

                  f. 1997  Stock  Option  Plan.  The  Option  evidenced  by this
Agreement  is granted  pursuant to the Plan,  a copy of which Plan has been made
available  to Optionee  and is hereby  incorporated  into this  Agreement.  This
Agreement is subject to and in all respects  limited and conditioned as provided
in the Plan.  The Plan governs this Option and, in the event of any questions as
to the  construction of this Agreement or in the event of a conflict between the
Plan and this  Agreement,  the Plan shall govern,  except as the Plan  otherwise
provides.

                  g. Lockup Period Limitation. Optionee agrees that in the event
the Company advises  Optionee that it plans an  underwritten  public offering of
its Common Stock in compliance with the Securities Act of 1933, as amended,  and
that  the  underwriter(s)  seek  to  impose  restrictions  under  which  certain
shareholders  may not sell or  contract  to sell or grant  any  option to buy or
otherwise  dispose  of  part  or all  of  their  stock  purchase  rights  of the
underlying Common Stock,  Optionee hereby agrees that for a period not to exceed
180 days from the date of the prospectus,  Optionee will not sell or contract to
sell or grant an option to buy or otherwise dispose of this option or any of the
underlying  shares of Common  Stock  without  the prior  written  consent of the
underwriter(s) or its representative(s).

                  h.  Blue  Sky  Limitation.  Notwithstanding  anything  in this
Agreement to the contrary, in the event the Company makes any public offering of
its  securities and  determines in its sole  discretion  that it is necessary to
reduce the  number of issued  but  unexercised  stock  purchase  rights so as to
comply  with any  state  securities  or Blue Sky law  limitations  with  respect
thereto,  the Board of  Directors  of the  Company  shall  have the right (i) to
accelerate the  exercisability  of this Option and the date on which this Option
must be  exercised,  provided  that the  Company  gives  Optionee 15 days' prior
written  notice of such  acceleration,  and (ii) to cancel  any  portion of this
Option or any other option granted to Optionee pursuant to the Plan which is not
exercised prior to or contemporaneously with such public offering.  Notice shall
be deemed given when delivered personally or when deposited in the United States
mail,  first class  postage  prepaid and addressed to Optionee at the address of
Optionee on file with the Company.

                  i. Accounting Compliance. Optionee agrees that, in the event a
"change of control  transaction" (as defined in Paragraph 2(c) above) is treated
as a "pooling of interests" under generally accepted  accounting  principles and
Optionee  is an  "affiliate"  of the  Company or any  Subsidiary  (as defined in
applicable  legal  and  accounting  principles)  at the time of such  change  of
control  transaction,  Optionee will comply with all requirements of Rule 145 of
the Securities Act of 1933, as amended, and the requirements of such other legal
or accounting  principles,  and will execute any  documents  necessary to ensure
such compliance.

                  j.  Stock  Legend.  If  applicable,  the  Company  may  put an
appropriate  legend on the certificates for any shares of Common Stock purchased
by Optionee  (or, in the case of death,  Optionee's  successors)  to reflect the
restrictions of Paragraphs 4(b), 4(g), 4(h) and 4(i) of this Agreement.


<PAGE>

                  k. Scope of Agreement.  This Agreement shall bind and inure to
the benefit of the Company and its  successors  and assigns and Optionee and any
successor or successors of Optionee permitted by Paragraph 4(e) above.

                  l. Arbitration. Any dispute arising out of or relating to this
Agreement  or the  alleged  breach  of it,  or the  making  of  this  Agreement,
including  claims of fraud in the  inducement,  shall be  discussed  between the
disputing parties in a good faith effort to arrive at a mutual settlement of any
such controversy.  If,  notwithstanding,  such dispute cannot be resolved,  such
dispute  shall be  settled  by  binding  arbitration.  Judgment  upon the  award
rendered  by the  arbitrator  may be  entered in any court  having  jurisdiction
thereof. The arbitrator shall be a retired state or federal judge or an attorney
who has practiced  securities or business  litigation for at least ten years. If
the parties cannot agree on an arbitrator  within 20 days, any party may request
that the chief  judge of the  District  Court for  Hennepin  County,  Minnesota,
select an arbitrator.  Arbitration will be conducted  pursuant to the provisions
of  this  Agreement,  and  the  commercial  arbitration  rules  of the  American
Arbitration Association,  unless such rules are inconsistent with the provisions
of this Agreement. Limited civil discovery shall be permitted for the production
of documents and taking of  depositions.  Unresolved  discovery  disputes may be
brought to the attention of the arbitrator who may dispose of such dispute.  The
arbitrator  shall have the  authority to award any remedy or relief that a court
of this  state  could  order or  grant;  provided,  however,  that  punitive  or
exemplary  damages  shall  not be  awarded.  The  arbitrator  may  award  to the
prevailing party, if any, as determined by the arbitrator,  all of its costs and
fees,  including the arbitrator's  fees,  administrative  fees, travel expenses,
out-of-pocket  expenses and reasonable  attorneys' fees. Unless otherwise agreed
by the  parties,  the place of any  arbitration  proceedings  shall be  Hennepin
County, Minnesota.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed on the day and year first above written.

                       NONQUALIFIED STOCK OPTION AGREEMENT


         THIS AGREEMENT,  made effective as of this _____ day of ______________,
199__, by and between  DATAKEY,  INC., a Minnesota  corporation (the "Company"),
and _____________________________ ("Optionee").


                                                W I T N E S S E T H:

         WHEREAS,  Optionee  on the  date  hereof  is a key  employee,  officer,
director, consultant or advisor of the Company or one of its Subsidiaries; and

         WHEREAS,  the Company  wishes to grant a  nonqualified  stock option to
Optionee  to  purchase  shares of the  Company's  Common  Stock  pursuant to the
Company's 1997 Stock Option Plan (the "Plan"); and

         WHEREAS,  the  Administrator has authorized the grant of a nonqualified
stock option to Optionee and has  determined  that, as of the effective  date of
this  Agreement,  the fair market value of the  Company's  Common Stock is $ per
share;

         NOW,  THEREFORE,  in  consideration  of the  premises and of the mutual
covenants herein contained, the parties hereto agree as follows:

         1. Grant of Option.  The Company  hereby grants to Optionee on the date
set forth above (the "Date of Grant"),  the right and option (the  "Option")  to
purchase all or portions of an aggregate of ____________ (____) shares of Common
Stock at a per share  price of  $______  on the terms and  conditions  set forth
herein, subject to adjustment pursuant to Section 13 of the Plan. This Option is
a  nonqualified  stock  option  and will not be treated  as an  incentive  stock
option,  as defined  under  Section  422,  or any  successor  provision,  of the
Internal  Revenue Code of 1986,  as amended (the  "Code"),  and the  regulations
thereunder.

         2. Duration and Exercisability.

                  a. The term during  which this Option may be  exercised  shall
terminate on  _______________,  20__, except as otherwise provided in Paragraphs
2(b) through 2(e) below. This Option shall become  exercisable  according to the
following schedule:

         Vesting Date                                Percentage/Number of Shares





<PAGE>

Once the Option becomes  exercisable to the extent of one hundred percent (100%)
of the  aggregate  number of shares  specified  in  Paragraph  1,  Optionee  may
continue  to  exercise  this  Option  under  the terms  and  conditions  of this
Agreement  until the termination of the Option as provided  herein.  If Optionee
does not  purchase  upon an  exercise  of this  Option the full number of shares
which  Optionee is then  entitled to purchase,  Optionee  may purchase  upon any
subsequent   exercise  prior  to  this  Option's   termination  such  previously
unpurchased  shares in  addition  to those  Optionee  is  otherwise  entitled to
purchase.

                  b. Termination of Relationship  (other than Change of Control,
Disability or Death). If Optionee ceases to be an employee, director, consultant
or an advisor of the Company or any Subsidiary for any reason other than because
of a "transaction" or "change of control  transaction" as described in Paragraph
2(c) or because of disability or death,  this Option shall completely  terminate
on the earlier of (i) the close of business on the three-month  anniversary date
of the  termination of all such  relationships,  and (ii) the expiration date of
this Option  stated in  Paragraph  2(a) above.  In such  period  following  such
termination,  this Option shall be exercisable only to the extent the Option was
exercisable on the vesting date  immediately  preceding the date on which all of
Optionee's relationships with the Company or Subsidiary have terminated, but had
not previously  been  exercised.  To the extent this Option was not  exercisable
upon the termination of such relationship,  or if Optionee does not exercise the
Option within the time specified in this Paragraph  2(b), all rights of Optionee
under this Option shall be forfeited.

                  c.  Change  of  Control.  If  (i)  Optionee  ceases  to  be an
employee,  director,  consultant  or  advisor of the  Company or any  Subsidiary
because of a "transaction"  or "change of control  transaction"  (as those terms
are defined in Section 13 of the Plan),  (ii) such  transaction  is treated as a
"pooling of interests" under generally accepted accounting principles, and (iii)
Optionee is an "affiliate" of the Company or Subsidiary  under  applicable legal
and accounting  principles,  this Option shall completely terminate on the later
of (A)  the  close  of  business  on the  three-month  anniversary  date  of the
termination of all such  relationships  with the Company or any Subsidiary,  and
(B) the close of  business  on the date that is 60 days  after the date on which
affiliates  are no longer  restricted  from selling,  transferring  or otherwise
disposing of the shares of stock received in the change of control  transaction.
In such period following such termination,  this Option shall become immediately
exercisable  unless the  acceleration of the  exercisability  of this Option has
been prevented as provided in Section 13 of the Plan, in which case, this Option
shall be  exercisable  only to the  extent the  Option  was  exercisable  on the
vesting date immediately preceding such termination of Optionee's  relationships
with the Company or Subsidiary,  but had not previously been  exercised.  To the
extent  this  Option  was  not  exercisable   upon  such   termination  of  such
relationships,  or if  Optionee  does not  exercise  the Option  within the time
specified in this Paragraph 2(c), all rights of Optionee under this Option shall
be forfeited.

                  d. Disability. If Optionee ceases to be an employee, director,
consultant or advisor of the Company or any Subsidiary because of disability (as
such term is defined in Code Section 22(e)(3), or any successor provision), this
Option shall completely terminate on the earlier of (i) the close of business on
the twelve-month  anniversary date of the termination of all such  relationships
with the  Company or any  Subsidiary,  and (ii) the  expiration  date under this
Option  stated  in  Paragraph  2(a)  above.   In  such  period   following  such
termination,  this Option shall be exercisable only to the extent the Option was
exercisable on the vesting date immediately  preceding the termination of all of
Optionee's  relationships.  If Optionee  does not exercise the Option within the
time specified in this Paragraph  2(d), all rights of Optionee under this Option
shall be forfeited.

                  e. Death. In the event of Optionee's  death, this Option shall
terminate  on the  earlier  of (i) the  close of  business  on the  twelve-month
anniversary  date of the date of Optionee's  death, and (ii) the expiration date
of this  Option  stated  in  Paragraph  2(a)  above.  In such  period  following
Optionee's  death, this Option may be exercised by the person or persons to whom
Optionee's  rights under this Option shall have passed by Optionee's  will or by
the  laws  of  descent  and  distribution  only to the  extent  the  Option  was
exercisable  on the vesting date  immediately  preceding  the date of Optionee's
death.  If such person or persons fail to exercise  this Option  within the time
specified  in this  Paragraph  2(e),  all  rights  under  this  Option  shall be
forfeited.

         3. Manner of Exercise.

                  a. General.  The Option may be exercised  only by Optionee (or
other  proper  party  in the  event  of death  or  incapacity),  subject  to the
conditions  of the Plan and  subject to such other  administrative  rules as the
Administrator may deem advisable, by delivering within the option period written
notice of exercise  to the Company at its  principal  office.  The notice  shall
state the number of shares as to which the Option is being  exercised  and shall
be accompanied by payment in full of the option price for all shares  designated
in the notice. The exercise of the Option shall be deemed effective upon receipt
of such notice by the Company and upon payment that  complies  with the terms of
the Plan and this  Agreement.  The Option may be  exercised  with respect to any
number  or all of the  shares  as to  which  it can then be  exercised  and,  if
partially exercised, may be exercised as to the unexercised shares any number of
times during the option period as provided herein.

                  b. Form of  Payment.  Payment of the option  price by Optionee
shall be in the form of cash,  personal  check,  certified  check or  previously
acquired shares of Common Stock of the Company, or any combination  thereof. Any
stock so  tendered  as part of such  payment  shall be valued at its Fair Market
Value as  provided in the Plan.  For  purposes  of this  Agreement,  "previously
acquired  shares of Common Stock" shall include  shares of Common Stock that are
already owned by Optionee at the time of exercise.

                  c. Stock Transfer  Records.  As soon as practicable  after the
effective exercise of all or any part of the Option,  Optionee shall be recorded
on the stock transfer books of the Company as the owner of the shares purchased,
and the  Company  shall  deliver  to  Optionee  one or more  duly  issued  stock
certificates evidencing such ownership. All requisite original issue or transfer
documentary stamp taxes shall be paid by the Company.


<PAGE>

         4. Miscellaneous.

                  a. Rights as  Shareholder.  This Agreement shall not confer on
Optionee any right with respect to the continuance of any relationship  with the
Company or any of its  Subsidiaries,  nor will it  interfere in any way with the
right of the Company to terminate any such relationship.  Optionee shall have no
rights as a shareholder with respect to shares subject to this Option until such
shares have been issued to Optionee upon exercise of this Option.  No adjustment
shall  be made  for  dividends  (ordinary  or  extraordinary,  whether  in cash,
securities  or other  property),  distributions  or other  rights  for which the
record date is prior to the date such  shares are issued,  except as provided in
Section 13 of the Plan.

                  b. Securities Law Compliance. The exercise of all or any parts
of this Option  shall only be  effective  at such time as counsel to the Company
shall have determined that the issuance and delivery of Common Stock pursuant to
such  exercise  will not violate any state or federal  securities or other laws.
Optionee may be required by the Company,  as a condition of the effectiveness of
any  exercise of this  Option,  to agree in writing  that all Common Stock to be
acquired  pursuant  to such  exercise  shall be held,  until such time that such
Common  Stock is  registered  and freely  tradable  under  applicable  state and
federal  securities  laws,  for  Optionee's  own  account  without a view to any
further  distribution  thereof and that such shares will be not  transferred  or
disposed of except in compliance  with applicable  state and federal  securities
laws.

                  c. Mergers, Recapitalizations, Stock Splits, Etc. Pursuant and
subject to Section 13 of the Plan, certain changes in the number or character of
the Common Stock of the Company (through sale, merger, consolidation,  exchange,
reorganization,     divestiture    (including    a    spin-off),    liquidation,
recapitalization,  stock split,  stock dividend or otherwise) shall result in an
adjustment,  reduction or enlargement, as appropriate, in Optionee's rights with
respect to any unexercised portion of the Option (i.e., Optionee shall have such
"anti-dilution"  rights under the Option with respect to such events,  but shall
not have "preemptive" rights).

                  d. Withholding Taxes. In order to permit the Company to comply
with all applicable federal or state income tax laws or regulations, the Company
may take such action as it deems  appropriate to insure that, if necessary,  all
applicable federal or state payroll, income or other taxes are withheld from any
amounts payable by the Company to Optionee. If the Company is unable to withhold
such federal and state taxes, for whatever reason, Optionee hereby agrees to pay
to the Company an amount  equal to the amount the  Company  would  otherwise  be
required to withhold  under federal or state law.  Optionee may,  subject to the
approval and discretion of the Administrator or such administrative rules it may
deem  advisable,  elect  to  have  all or a  portion  of  such  tax  withholding
obligations  satisfied by delivering shares of the Company's Common Stock having
a fair market value equal to such obligations.

                  e.  Nontransferability.  During the lifetime of Optionee,  the
accrued  Option  shall be  exercisable  only by  Optionee  or by the  Optionee's
guardian  or  other  legal  representative,  and  shall  not  be  assignable  or
transferable by Optionee, in whole or in part, other than by will or by the laws
of descent and distribution.


<PAGE>

                  f. 1997  Stock  Option  Plan.  The  Option  evidenced  by this
Agreement  is granted  pursuant to the Plan,  a copy of which Plan has been made
available  to Optionee  and is hereby  incorporated  into this  Agreement.  This
Agreement is subject to and in all respects  limited and conditioned as provided
in the Plan.  The Plan governs this Option and, in the event of any questions as
to the  construction of this Agreement or in the event of a conflict between the
Plan and this  Agreement,  the Plan shall govern,  except as the Plan  otherwise
provides.

                  g. Lockup Period Limitation. Optionee agrees that in the event
the Company advises  Optionee that it plans an  underwritten  public offering of
its Common Stock in compliance with the Securities Act of 1933, as amended,  and
that  the  underwriter(s)  seek  to  impose  restrictions  under  which  certain
shareholders  may not sell or  contract  to sell or grant  any  option to buy or
otherwise  dispose  of  part  or all  of  their  stock  purchase  rights  of the
underlying Common Stock,  Optionee hereby agrees that for a period not to exceed
180 days from the date of prospectus, Optionee will not sell or contract to sell
or grant an  option to buy or  otherwise  dispose  of this  option or any of the
underlying  shares of Common  Stock  without  the prior  written  consent of the
underwriter(s) or its representative(s).

                  h.  Blue  Sky  Limitation.  Notwithstanding  anything  in this
Agreement to the contrary, in the event the Company makes any public offering of
its  securities and  determines in its sole  discretion  that it is necessary to
reduce the  number of issued  but  unexercised  stock  purchase  rights so as to
comply  with any  state  securities  or Blue Sky law  limitations  with  respect
thereto,  the Board of  Directors  of the  Company  shall  have the right (i) to
accelerate the  exercisability  of this Option and the date on which this Option
must be  exercised,  provided  that the  Company  gives  Optionee 15 days' prior
written  notice of such  acceleration,  and (ii) to cancel  any  portion of this
Option or any other option granted to Optionee pursuant to the Plan which is not
exercised prior to or contemporaneously with such public offering.  Notice shall
be deemed given when delivered personally or when deposited in the United States
mail,  first class  postage  prepaid and addressed to Optionee at the address of
Optionee on file with the Company.

                  i. Accounting Compliance. Optionee agrees that, in the event a
"change of control  transaction" (as defined in Paragraph 2(c) above) is treated
as a "pooling of interests" under generally accepted  accounting  principles and
Optionee  is an  "affiliate"  of the  Company or any  Subsidiary  (as defined in
applicable  legal  and  accounting  principles)  at the time of such  change  of
control  transaction,  Optionee will comply with all requirements of Rule 145 of
the Securities Act of 1933, as amended, and the requirements of such other legal
or accounting  principles,  and will execute any  documents  necessary to ensure
such compliance.

                  j.  Stock  Legend.  If  applicable,  the  Company  may  put an
appropriate  legend on the certificates for any shares of Common Stock purchased
by Optionee  (or, in the case of death,  Optionee's  successors)  to reflect the
restrictions of Paragraphs 4(b), 4(h), 4(i) and 4(j) of this Agreement.


<PAGE>

                  k. Scope of Agreement.  This Agreement shall bind and inure to
the benefit of the Company and its  successors  and assigns and Optionee and any
successor or successors of Optionee permitted by Paragraph 4(e) above.

                  l. Arbitration. Any dispute arising out of or relating to this
Agreement  or the  alleged  breach  of it,  or the  making  of  this  Agreement,
including  claims of fraud in the  inducement,  shall be  discussed  between the
disputing parties in a good faith effort to arrive at a mutual settlement of any
such controversy.  If,  notwithstanding,  such dispute cannot be resolved,  such
dispute  shall be  settled  by  binding  arbitration.  Judgment  upon the  award
rendered  by the  arbitrator  may be  entered in any court  having  jurisdiction
thereof. The arbitrator shall be a retired state or federal judge or an attorney
who has practiced  securities or business  litigation for at least ten years. If
the parties cannot agree on an arbitrator  within 20 days, any party may request
that the chief  judge of the  District  Court for  Hennepin  County,  Minnesota,
select an arbitrator.  Arbitration will be conducted  pursuant to the provisions
of  this  Agreement,  and  the  commercial  arbitration  rules  of the  American
Arbitration Association,  unless such rules are inconsistent with the provisions
of this Agreement. Limited civil discovery shall be permitted for the production
of documents and taking of  depositions.  Unresolved  discovery  disputes may be
brought to the attention of the arbitrator who may dispose of such dispute.  The
arbitrator  shall have the  authority to award any remedy or relief that a court
of this  state  could  order or  grant;  provided,  however,  that  punitive  or
exemplary  damages  shall  not be  awarded.  The  arbitrator  may  award  to the
prevailing party, if any, as determined by the arbitrator,  all of its costs and
fees,  including the arbitrator's  fees,  administrative  fees, travel expenses,
out-of-pocket  expenses and reasonable  attorneys' fees. Unless otherwise agreed
by the  parties,  the place of any  arbitration  proceedings  shall be  Hennepin
County, Minnesota.

         IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be
executed on the day and year first above written.

Comparison of 1997 with 1996

Total  Revenue:  Total  revenue was  $5,977,000 in 1997, a decrease of 9 percent
from  $6,558,000  in 1996.  The revenue  decrease is  primarily  due to customer
requested  delays in major  electronic  products  customer  shipments during the
second half of 1997  resulting  from delays,  cancellation,  or  non-renewal  of
orders from their  customers.  The Company  anticipates that sales of electronic
products  will  continue  to  decrease  in 1998.  Its future  growth will depend
primarily on the market  acceptance of new end-user  products  introduced to the
information security marketplace.

Gross margins:  The gross profit margin  decreased to 27 percent in 1997 from 35
percent in 1996 primarily as a result of lower revenue, product costs associated
with zero charge  evaluation  units to customers,  and increases in reserves for
inventory obsolescence.

Research and development: Research and development expenses increased 41 percent
to $3,186,000 in 1997 from  $2,263,000 in 1996 due to the Company's  significant
increase in product development activities for token-based  information security
systems.

Marketing and sales, General and administrative:  Marketing and sales expense in
1997 increased 31 percent to $1,716,000 from $1,312,000 in 1996 due to a planned
increase in product promotion expense to achieve market  introduction of the new
token-based information security systems.
   General and administrative  expenses decreased 38 percent to $713,000 in 1997
from  $1,156,000  in 1996  primarily due to an accrual in 1996 for severance pay
and benefits due the Company's former chief executive officer.

Interest  income:  Interest income decreased 53 percent to $170,000 in 1997 from
$361,000  in 1996 due to a  decline  in the  Company's  investment  in  interest
bearing investments.

Income tax  expense  (benefit):  The  Company  recorded an income tax expense of
$325,000 in 1997 as compared to an income tax benefit of $388,000 in 1996.  As a
result of the net operating  loss  carryover in excess of $5,000,000 at December
31, 1997, the Company  determined that the realization of the future tax benefit
of the operating  losses for tax purposes was uncertain  and,  accordingly,  the
deferred  tax asset of $325,000  recorded at December  31,  1996,  was  entirely
reserved and charged to expense in 1997.


<PAGE>

Comparison of 1996 with 1995

Total  Revenue:  Total  revenue was  $6,558,000 in 1996, a decrease of 9 percent
from  $7,219,000  in 1995.  The revenue  decrease was  primarily due to customer
requested  delays in commercial OEM product  shipments during the second half of
1996 resulting from delays in shipments to their customers.

Gross margins:  The gross profit margin  increased to 35 percent in 1996 from 33
percent in 1995 in spite of a reduction in revenue  which  normally  reduces the
margin percentage. The improved margin percentage was primarily due to increases
in  product   selling  prices  in  excess  of  the  increases  in  material  and
manufacturing costs.

Research  and  development:  Research and  development  expenses  increased  221
percent  to  $2,263,000  in 1996  from  $704,000  in 1995  due to the  Company's
significant  increase  in  product  development   activities  for  new  end-user
products.

Marketing and sales, General and administrative:  Marketing and sales expense in
1996  increased  17  percent to  $1,312,000  from  $1,124,000  in 1995 due to an
increase in product  promotion  expense for newly  developed and  in-development
end-user products.
   General and  administrative  expenses  increased 73 percent to  $1,156,000 in
1996 from  $670,000 in 1995  primarily  due to an accrual for  severance pay and
benefits due the Company's former chief executive officer.

Interest  income:  Interest income  decreased 6 percent to $361,000 in 1996 from
$381,000  in 1995 due to a  decline  in the  Company's  investment  in  interest
bearing investments.

Income tax  expense  (benefit):  Income tax  benefit  for 1996 was  $388,000  as
compared to an income tax expense of $106,000 in 1995. The benefit is related to
the 1996 loss  before  taxes of  $2,094,000  for which the  Company  recorded  a
deferred  tax asset of  $325,000,  and 1995  expense is related to the  $282,000
income before taxes.

Liquidity and Capital Resources

The  Company  had  a  reduction  of  $4,828,000  in  cash  and  held-to-maturity
marketable  debt securities in 1997 compared to a reduction of $834,000 in 1996.
The 1997 reduction in cash and marketable  debt  securities  resulted  primarily
from significant expenditures,  totaling $4,902,000, in research and development
and  marketing  expenses  principally  related  to  the  Company's  new  product
development activities. Inventory decreased $46,000 to $1,083,000 as of December
31, 1997,  compared to $1,129,000 as of December 31, 1996. Accrued  compensation
expense decreased by $129,000  primarily due to the payment of severance pay and
benefits due the Company's former chief executive officer.  The Company invested
$822,000 in the purchase of equipment and maintenance of licenses and patents in
1997, compared to $515,000 in 1996. The 1997 increase is primarily  attributable
to prepaid  license fees related to licensed  software that will be bundled with
the Company's  information  security systems and purchase of automated equipment
to improve  factory  efficiency.  Cash,  cash  equivalents,  and  investment  in
held-to-maturity  marketable  debt  securities as of December 31, 1997,  totaled
$1,305,000 as compared to $6,133,000 as of December 31, 1996. See "Outlook".
   Datakey's balance sheet reflects  $1,951,000 in working capital and a current
assets to current liabilities ratio of 2.7 to 1 as of December 31, 1997.

Outlook

Certain  statements in the following  Outlook section and in other parts of this
Annual Report are forward looking and are based upon current expectations. These
statements are forward  looking and actual results may differ  materially due to
risks and uncertainties, including those set forth below.

Revenue:  Shipment delays experienced in the second half of 1997 are expected to
continue through the first half of 1998 and likely will result in a reduction in
electronic  products  revenue  for the year as compared  to 1997.  New  end-user
products being introduced to the information  security  marketplace are expected
to result in significant revenue during the second half of 1998. If this revenue
meets  the  Company's  present  expectations,  the  total  revenue  from the new
products could exceed the revenue from the electronic products group.

Gross  margins:  A gradual  improvement  in gross profit  margins during 1998 is
expected through selective price increases,  effective material  purchasing,  an
increase  in revenue  without an  attendant  increase  in factory  overhead  and
improvements in manufacturing efficiency.

Research  and  development:  The  Company  will  continue  to fund  new  product
development activities in 1998 but at about 45 percent less than in 1997.

Marketing and sales,  General and  administrative:  Marketing and sales expenses
are  expected  to  increase  about 40  percent in 1998 to  support  new  product
introductions and the expected  increase in revenue,  but will be about the same
percent of revenue  provided  revenue  from new product  sales  materializes  as
expected.  General and administrative  expenses in 1998 are expected to increase
slightly from the 1997 level.

Interest income (expense):  Interest income is expected to decline materially in
early  1998 as the  Company  intends  to use cash and cash  equivalents  to fund
continuing product development and marketing activities to support the Company's
entry into advanced  information  security products.  Beginning in the second or
third quarter the Company expects to borrow money and begin  incurring  interest
expense under the recently arranged bank line of credit.

Income tax expense (benefit): As a result of a net operating loss carry-forward,
the Company  does not expect to record an income tax  benefit or expense  during
1998.

Expected first half loss: The Company expects to report a loss in the first half
of 1998 but may return to  profitability  by the end of 1998 if revenue from the
new product line materializes as expected.

Liquidity  and  capital  resources:  The Company  plans to continue  new product
development in 1998 at a lower level than in 1997 and marketing  activities will
continue  at an  increased  level  during  1998.  The  Company  expects to spend
$4,000,000 to $4,500,000 on these  activities.  Inventory levels are expected to
increase slightly in 1998 to support advanced  information  security products as
well as electronic  products.  1998  investments in equipment and maintenance of
licenses  and patents are expected to return to a level of $500,000 to $550,000.
The  Company  believes  its  working  capital  and cash  equivalent  investments
together  with  its bank  line of  credit  are  sufficient  to fund its  planned
operations and continued  development  and promotional  activities  during 1998,
provided that the revenue from new products  materialize  as expected.  The bank
line is scheduled to expire in May 1998,  but the Company  expects to be able to
renew it for another year. The Board of Directors believes the prudent course of
action is for the Company to seek additional debt or equity  financing,  and the
Company  is  currently   discussing   financing   options  with  several   local
broker-dealers.

Risks and Uncertainties

   Rapid technological change:  Datakey's information security end-user products
such as SignaSURE  CIP and  SignaSURE ESS will  integrate  hardware  tokens with
software   that   provides  a  much  higher  level  of  security  than  software
implementations  alone. There is a possibility that software-only  solutions may
overcome this deficiency in the future.
   Customer acceptance:  While Datakey performs market research and beta testing
to determine  the  viability of its new products,  actual user  acceptance  will
ultimately  dictate  the  success  of the  marketing  and sales  efforts  of new
products such as SignaSURE CIP and ESS.  Although the Company  believes that the
decision to fund these new  products is correct,  there are no  assurances  that
investments already made and additional investments planned for 1998 will result
in a financial return.
   Product delivery schedules:  Delays in the release of new products will cause
operational inefficiencies, increased development costs and reduced revenues.
   Price  competition:  While  Datakey  believes  that its strategy of providing
token-based  product solutions at a price that is competitive with software-only
products is attainable,  there are no assurances that competitive pressures will
not force the Company to accept reduced margins to compete in the future.  Large
companies with  significantly  greater  resources  have  recognized the need for
information  security  and could  enter  this  market as  competitors  with much
greater  financial  resources.  A portion  of the new  end-user  products'  cost
consists of royalties and license fees which would need to be  re-negotiated  in
order to maintain acceptable profit margins.
   Integrated information security products: Although the Company's new products
will operate  seamlessly  with popular  application  programs,  new  application
programs that integrate  information security into their product could erode the
future market for these Datakey products.
   Marketing  and sales:  The future  revenue  of  Datakey  end-user  systems is
dependent  on the  success of a new and  untested  marketing  and  direct  sales
organization.
   Need for  information  security:  Corporate  utilization  of the Internet and
internal  intranets  dictate a need for information  security,  but there are no
assurances that other, more secure information transmission media may not become
available in the future that would preclude the need for the type of information
security provided by the Company's products.
   Financing: There is no assurance that the Company's current negotiations with
broker-dealers  will lead to a financing on acceptable terms.  Should there be a
delay in new orders or if new product revenue does not materialize to the extent
currently  projected,   the  inability  to  obtain  acceptable  financing  could
jeopardize the Company's ability to maintain its current business operations.

Other Matters

The Company has begun its analysis of the impact, if any, from the changeover of
various computer systems during the year 2000. Based upon its internal  analysis
and results of  questions  posed to major  software and service  suppliers,  the
Company feels that year 2000 will have no  significant  financial or operational
impact.
