                          DATAKEY, INC. AND SUBSIDIARY
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


GENERAL

In the opinion of management, the accompanying unaudited financial statements
contain all adjustments necessary to present fairly Datakey's financial position
as of October 2, 1999, and December 31, 1998, and results of its operations and
cash flows for the three-month and nine-month periods ended October 2, 1999, and
October 3, 1998. The adjustments that have been made are of a normal recurring
nature.

The accounting policies followed by the Company are set forth in Note 1 to the
Company's financial statements in the 1998 Datakey, Inc. Annual Report and in
Form 10-KSB for the year ended December 31, 1998.


PRIVATE COMMON STOCK FINANCING - RECENT EVENTS

The Company completed, in October 1999, a $1.5 million private equity financing
with 28 accredited investors. Each investor paid $1.25 per common share, with
each share accompanied by a ten-year warrant to purchase one common share for
$1.25. A portion of the proceeds was used to pay off the bank credit line and to
provide working capital.


OPERATING SEGMENTS

The Company adopted SFAS No. 131, Disclosures About Segments of an Enterprise
and Related Information, for the year ended December 31, 1998. This statement
requires public enterprises to report selected information about operating
segments in annual and interim reports issued to shareholders. The adoption of
this statement had no impact on the Company's financial condition or results of
operations.

The Company's reportable segments are strategic business units that offer
different products and services. They are managed separately because each
business requires different technology and marketing strategies. The Company has
two reportable segments: Electronic Products (EP) and Integrated Systems
Solutions (ISS). The Electronic Products segment produces and markets
proprietary memory keys, cards, and other custom-shaped tokens that serve as a
convenient way to carry electronic information. The Integrated Systems Solutions
segment produces and markets products for the information security market, which
enable user identification and authentication, secure data exchange, and
information validation.

The accounting policies of the segments are the same as those described in the
summary of significant accounting policies. There are no intersegment
transactions. The Company evaluates performance based on operating earnings of
the respective segments.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION
                          DATAKEY, INC. AND SUBSIDIARY
                  RESULTS OF OPERATIONS AND FINANCIAL CONDITION


RESULTS OF OPERATIONS

         REVENUE - Revenue for the three-month period ended October 2, 1999,
increased by $113,000, or 8 percent, compared to the same period in 1998. The
increase in revenue is due both to resumption in shipments to Electronic
Products (EP) customers during the quarter who had stopped shipments in the
second quarter, and an increase in shipments to Information Security Systems
(ISS) customers.

         Two major EP customers resumed shipments during the quarter and have
recently indicated their requirements for the year may exceed the total for
1998. Additionally, other EP customers are expected to increase shipments during
the fourth quarter of 1999, and the Company expects to secure several new pilot
programs in the ISS business units, as well as convert a few pilot programs to
production deployment phase during the balance of 1999. Should the Company be
successful in arranging new ISS pilot programs and production deployments, as
management currently expects, revenue for the 1999 fiscal year may equal or
exceed that achieved in 1998. The Company continues to expect an operating loss
for 1999, however, as the R&D and sales and marketing expenses related to the
ISS business unit will substantially exceed its revenue for at least several
quarters.

         GROSS PROFIT MARGIN - Gross profit as a percentage of revenue decreased
to 36 percent in the three-month period ended October 2, 1999 compared to 37
percent for the same period in 1998 and remained at 39 percent in the nine-month
period ended October 2, 1999. The reduction in margin in the three-month period
ended October 2, 1999, is primarily the result of unfavorable product mix. The
Company expects the gross profit margin as a percentage of revenue to remain at
the current levels, or improve slightly, for the balance of 1999.

         OPERATING EXPENSES - Operating expenses increased by $95,000 or 9
percent, and $527,000 or 16 percent in the three-month and nine-month periods,
ended October 2, 1999, respectively compared to the same periods in 1998. The
increases principally relate to a year to date increase of $133,000 in sales and
marketing expense to continue advertising and promoting the Company's ISS
product line. Research and development expense also increased $100,000 in the
three-month period and $329,000 in the nine-month period, as the Company
continued to develop more features and enhancements to its information security
products. Other expense increases result primarily from general inflationary
increases in rent, corporate insurance, and salaries.

         The Company expects to continue spending on product promotional and
product developmental activities at a rate that will trend upward on a quarterly
basis. General and administrative expenses are expected to remain at about the
level incurred in the third quarter.

         INTEREST INCOME - Interest income declined from $16,000 to $1,000 in
the three-month periods and from $40,000 to $2,000 in the nine-month periods,
ended October 2, 1999, compared to 1998 as proceeds from interest bearing
accounts were utilized to fund new product development and product promotion
activities, and the Company began borrowing on its working capital line of
credit. Interest income is expected to increase in the fourth quarter as the
Company has invested a portion of the proceeds of its recent private equity
placement in an interest-bearing account.

         FINANCIAL CONDITION - The Company experienced a decrease in cash and
cash equivalents of $834,000 for the nine-month period ended October 2, 1999.
The decreases in cash in 1999 resulted primarily from an increase in the
operating losses in the period.

         Datakey's balance sheet reflects $1,192,000 in working capital as of
October 2, 1999 and a current assets to current liabilities ratio of 2.00 to 1.
The Company expects to continue spending on R&D and on marketing and sales
activities at an increased amount compared to 1998. Inventory and accounts
receivable levels are expected to increase during the balance of 1999 to support
the expected ramp-up in revenue from the Company's new information security
products. The Company believes that its $1.5 million private equity financing,
which closed in late October 1999, in addition to its $1 million bank line of
credit, renewed in April 1999 for an additional year, will be sufficient to fund
its operation until at least mid 2000. Beyond that point, the Company's need for
additional financing depends largely on its success in selling more pilot units
to customers and converting ISS customers from the pilot to the production
phase. There is no assurance that a significant increase in ISS sales will occur
or that any necessary capital will be available on terms satisfactory to the
Company, or at all.

         YEAR 2000 - The Company began addressing the Year 2000 issue in 1997
using a multi-step approach, including inventory and assessment, remediation and
testing, and contingency planning. The Company, with the assistance of outside
consultants, began by analyzing and testing its major internal software programs
to determine the level of compliance with the changeover in Year 2000. At this
point, the Company believes all "mission critical" systems are materially
compliant.

         The Company is currently seeking assurances from key suppliers and
customers regarding their Year 2000 readiness. The Company has not yet completed
this part of the assessment phase and cannot predict the outcomes of other
companies' remediation efforts.

         The Company currently plans to substantially complete its Year 2000
compliance efforts by November 30, 1999. The Company has also formed a team to
develop contingency plans in the event certain suppliers are unable to deliver
critical parts and components in early 2000. At this time, the Company believes
that its most reasonably likely worst case scenario is that the Company could
experience delays in delivery of critical parts and supplies and/or key
customers could experience a delay in delivery of needed Datakey parts. In the
event that either of these scenarios occurs, the Company expects that it would
have a material adverse effect on the Company's financial condition and results
of operations.

         The Company estimates that the total cost of efforts, in 1999, to make
hardware and software Year 2000 compliant, will be approximately $20,000.

FORWARD-LOOKING STATEMENTS AND RISKS

As provided for under the Private Securities Litigation Reform Act of 1995, the
Company wishes to caution investors that the following important factors, among
others, in some cases have affected and in the future could affect the Company's
actual results of operations and cause such results to differ materially from
those anticipated in forward-looking statements made in this document.

o    The expectations that the Company's revenues may equal or exceed those of
     1998 due to (i) EP customers increasing shipments during the remainder of
     1999; (ii) new pilot programs emerging within the ISS business unit; and
     (iii) the conversion of current pilot programs to the production deployment
     phase depends on the new products performing as currently anticipated,
     market acceptance of the products in general, the potential introduction of
     competitive products, the sales cycle and timing of commitments from
     potential customers, in addition to general competitive and market
     conditions.

o    The expectation of gross profit margin remaining at current level or
     improving slightly depends on the Company's ability to control costs as
     necessary.

o    The expectation that interest income will increase for the fourth quarter
     of 1999 depends on the interest rates in the market and other general
     market conditions, as well as the ability to retain the recently acquired
     funds in an interest bearing account as long as possible.

o    The ability of the Company to fund operations as least through mid-2000
     depends in large part on the Company's ability to sell more pilot units
     within its ISS segment and on current ISS customers converting from the
     pilot to the production phase.

o    The impact of Year 2000 issues on its business depends on the accuracy,
     reliability, and effectiveness of the Company's and its suppliers' and
     customers' assessment and remediation of Year 2000 issues.

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

On October 29, 1999, the Company issued an aggregate of 1,200,000 shares of
common stock at $1.25 per share and ten-year warrants to purchase 1,200,000
shares of common stock at $1.25 for gross proceeds of $1,500,000. The shares
were sold with the assistance of Miller, Johnson & Kuehn, Incorporated (MJK) to
28 accredited investors. MJK received commissions equal to $144,000 plus
accountable expenses as part of the offering, and ten-year warrants to purchase
120,000 shares of Common Stock, with an exercise price of $1.375 per share.
Because the offering was not a public offering and was offered only to
accredited investors, the Company relied upon Section 4 (6) and Rule 506 of
Regulation D of the Securities Act of 1933, as amended, for exemptions from the
registration requirements of such Act. The Company will file, by November 30,
1999, a Registration Statement on Form S-3 covering the resale of the shares of
Company Common Stock issued in connection with the offering and those shares
issuable upon exercise of the agent and investor warrants.

On November 11, 1999 the Company issued an aggregate of 940,000 shares of Common
Stock to Special Situations Private Equity Fund, L.P. and Special Situations
Technology Fund, L.P. (the "Special Situations Funds") in exchange for the
Special Situations Funds (i) surrendering all outstanding 74,367 shares of the
Company's Series A Convertible Preferred Stock (with such shares issuable upon
exercise included in the aggregate 940,000), and releasing the Company of any
dividend obligations and antidilution adjustments, and (ii) surrendering all
warrants held by the Special Situations Funds to the Company, again forfeiting
any antidilution or other adjustments that may result due to the October 1999
financing. As additional consideration for the issuance of the Common Stock, the
Special Situations Funds executed a waiver of any and all rights they have or
might have to bring any action against the Company and its affiliates, whether
for damages or equitable remedies, arising out of either their purchase of
securities in the May 1998 offering or relating to Datakey's 1999 private
offerings of Common Stock and warrants.
