ITEM 1.        BUSINESS.

GENERAL

             Data Systems Network Corporation ("Data Systems"), incorporated in
Michigan in 1986, provides computer network services and products that allow
companies to control their complex distributed computing environments, allowing
companies to capitalize on their investments in technology and people. Data
Systems' wide range of services includes Applications Development, Network
Services, Enterprise Management, Help Desk and Security Services. Data Systems
also provides a wide range of network integration services including
installation, consultation, technical support and training to governmental and
corporate accounts.

             In February 1996, Data Systems acquired 70% of the common stock of
Unified Network Services, Inc. ("UNS"), a start-up network management operation
based in Raleigh, North Carolina. Data Systems also acquired the Network Systems
Group ("NSG") of SofTech, Inc. in September 1996 for 540,000 shares of Data
Systems' Common Stock and $890,000 in cash. During 1998, Data Systems sold its
interest in UNS, effective June 1, 1998.

RECENT DEVELOPMENTS

               On February 1, 1999, Data Systems announced that a definitive
merger agreement was signed with Alydaar Software Corporation now known as
Information Architects Corp. of Charlotte, North Carolina. Under the terms of
the agreement, approved by the Board of Directors of both companies, Information
Architects was to exchange 1.6 million shares of its common stock for all
outstanding shares of Data Systems' stock.

               On September 15, 1999, Data Systems and Information Architects
mutually agreed to terminate their Agreement and Plan of Merger dated January
31, 1999. As a result of the termination, Information Architects signed a
promissory note payable to Data Systems in the amount of $250,000 as
reimbursement for expenses incurred as a result of the terminated merger. The
note will be repaid in 10 equal installments of $25,000. Payments began October
1, 1999 and will end July 1, 2000. Payments for the period October 1999 through
March 2000 have been received.

                                       2

               On February 17, 1999, Data Systems announced that it had agreed
to a stipulation of settlement of the consolidated complaint in the shareholder
class action lawsuit captioned, In Re: Data Systems Network Corporation
Securities Litigation, Case No. 98-70854. The stipulation of settlement was
filed in federal court in Detroit, Michigan and the court determined the
settlement to be fair on May 24, 1999. Under the terms of the settlement, and
subject to various conditions, Data Systems created a gross settlement fund. The
fund benefits a settlement class of purchasers who bought Data Systems' stock
during the period from May 16, 1996 through February 24, 1998. The fund was
comprised of $900,000 provided by Data Systems' insurer, and 650,000 shares of
Data Systems' common stock which were issued June 22, 1999. In agreeing to the
settlement, Data Systems and individual defendants made no admission of any
wrongdoing.

               On February 18, 2000, Data Systems and TekInsight.Com, Inc.
("TekInsight") entered into an Agreement and Plan of Merger pursuant to which
Data Systems will be merged (the "Merger") into Astratek, Inc., a wholly owned
and operating subsidiary of TekInsight. In consideration for the Merger, Data
Systems' shareholders will receive a number of shares of a new class of
TekInsight convertible preferred stock with a value (the "Merger Price") which
will equal $12,500,000 if the market price of Tekinsight's common stock at the
time of closing (the "Market Price") is less than $5.00 per share, $16,000,000
if the Market Price is between $5.00 and $7.00 per share, and $18,000,000 if the
Market Price is over $7.00 per share. The new class of TekInsight convertible
preferred stock is proposed to be listed on the Nasdaq Small Cap market, with
the aggregate number of such shares to be issued determined by dividing the
applicable Merger Price by the Market Price. Completion of the Merger is subject
to a number of conditions, including receipt of TekInsight and Data Systems
shareholder approval, acceptance by Nasdaq for the listing of the convertible
preferred stock and other customary closing conditions. There can be no
assurance the Nasdaq listing will be obtained for the newly issued convertible
preferred stock, or that any of the closing conditions will be satisfied.
Although no assurances can be given, the parties intend to close the merger no
later than June 30, 2000.




PRODUCTS AND SERVICES

               Data Systems' principal business is to provide computer network
services and products that allow companies to control their complex distributed
computing environments. Such services include the design, sale and service of
local area networks ("LANs") and wide area networks ("WANs"). Data Systems
generates revenues by providing consulting and network installation services,
selling add-on hardware components to existing clients and providing
after-installation service and support, training services and network management
services. Data Systems is an authorized dealer, reseller or integrator for the
products of many major vendors, including, but not limited to: Compaq, Sun
Microsystems, Dell, Nortel Networks, Hewlett-Packard, Novell, Microsoft, Cisco,
Meridian Data, 3COM, Intel, and Oracle. Data Systems has developed applications
for remote network management and can sell private label computer systems,
primarily to state governments. In addition, the Company provides application
development services in database management.

               Resellers who meet specified qualifications receive customer
referrals and recommendations and advanced technical assistance and support from
certain manufacturers, giving the qualifying resellers a competitive advantage
over other resellers in the market. These qualifications vary from manufacturer
to manufacturer and typically include some or all of the following components:
specific training for technical personnel, specific training for sales
personnel, possession of certain advanced equipment, ongoing training
requirements, and minimum purchase targets. The process of obtaining and
maintaining these manufacturer authorizations is time consuming and has costs
associated with obtaining and maintaining a single authorization. These costs
include, but are not limited to, acquisition of hardware, software, facilities
and spare parts, training fees, personnel and travel expenses and fees paid to
the manufacturer for certification.

               Data Systems generally sells equipment in conjunction with its
higher margin network engineering services. These services include design,
consulting, installation, and network administration for both LANs and WANs.
Data Systems provides turnkey implementation and support services and, for some
customers, on-site support personnel who work in conjunction with the customer's
personnel on a continuous basis.

               Data Systems also provides on-going technical and maintenance
support through a variety of service programs tailored to fit each specific
customer's service needs and budget. These programs include a two-hour response
service for critical network components, help desk, Computer Associates
Unicenter and dispatch services. Data Systems generally passes through
warranties provided by manufacturers to the purchaser. Data Systems offers no
warranty separate from manufacturers' warranties.

MARKETING AND CUSTOMERS

             Data Systems markets its products and services through its internal
sales force. Data Systems has sales and service personnel in the following
states: Florida, Louisiana, Massachusetts, Michigan and New York. Data Systems
has no retail sales outlets and has no intention of entering the retail market.

             Data Systems directs its marketing efforts at state and local
governments, Fortune 1000 and middle market corporations and institutional users
such as hospitals and universities. Current marketing efforts are generally
focused on customers located in the states in which the Company has offices.

             The State of Michigan accounted for 4% of Data Systems' revenue in
1999 and 29% of Data Systems' revenue in each of 1998 and 1997. Purchases by
agencies of the State of Michigan were made pursuant to a blanket agreement,
which expired in September 1998. Data Systems continues to provide network
services and maintenance services to the State of Michigan through a third-party
master contractor blanket purchase order. As with all of Data Systems' service
contracts and purchase orders, there are no assurances that any contract can be
extended further or that, if re-bid, Data Systems will be awarded a new
agreement under the same terms and conditions.


                                       4

<PAGE>   5
             The State of New York accounted for 25% of Data Systems' revenue in
1999 and 12% of Data Systems' revenue in 1998. Data Systems was awarded a
three-year contract, renewable in one-year increments, to provide system
peripheral equipment. The first year expired May 1999. The contract was renewed
and the second year expires May 2000. Data Systems is also an authorized
reseller of Novell, Nortel Systems and Cisco products and software to the State
of New York.

VENDORS

             Data Systems purchases the microcomputers and related products it
sells directly from manufactures and indirectly through distributors such as
Merisel, Tech Data and Ingram Micro Corporation. In general, Data Systems must
be authorized by a manufacturer in order to sell its products, whether the
products are purchased from distributors or directly from manufacturers. Data
Systems is an authorized reseller for microcomputers, workstations, and related
products of over 50 manufacturers. Sales by Data Systems of products
manufactured by Compaq, Hewlett-Packard, Cisco, Novell, Sun Microsystems, Nortel
Networks, Dell, and IBM accounted for between 35% an 40% of revenues during each
of the last three fiscal years. However, sales of commodity products, such as
IBM and Dell, have substantially declined over this period. Typically, vendor
agreements provide that Data Systems has been appointed, on a non-exclusive
basis, as an authorized reseller of specified products at specified locations.
The agreements generally are terminable on 30 to 90 days' notice or immediately
upon the occurrence of certain events, and are subject to periodic renewal. The
loss of a major manufacturer or the deterioration of Data Systems' relationship
with a major manufacturer could have a material adverse effect on Data Systems'
business as certain product offerings that are requested by customers would not
be available to Data Systems.

             Data Systems determines whether to purchase products from
distributors or directly from manufacturers by surveying prices and product
availability among the manufacturers and the distributors with whom it has
contractual relationships. Distributors, which purchase products in large
quantities, often are able to offer a better price on products due to volume
discounts granted by manufacturers. Data Systems' agreement with Ingram Micro,
through which it made 17.6% of its product purchases in 1999, provides
competitive pricing, inventory and asset management terms and conditions. The
loss of Data Systems' relationships with distributors could result in higher
product prices to Data Systems and potentially reduce Data Systems' profit
margins. Data Systems believes, however, that the loss of its relationship with
any particular distributor would not have a material adverse effect on Data
Systems' results of operations or financial condition due to the availability of
other sources of supply.

COMPETITION

             The network integration market is highly competitive. Data Systems
competes with different classes of competitors, depending on the type of
business opportunity. For project-oriented sales, Data Systems competes with
system integrators and with computer hardware manufacturers. Data Systems also
competes with a wide variety of local, regional and national hardware resellers
for add-on equipment sales. Because Data Systems is not as price-aggressive as
some of these competitors, Data Systems relies on its sales force to provide
superior servicing and post-sale technical support to maintain its customer
relationships. Depending on the customer, Data Systems competes on the basis of
technological capability, price, breadth of product offerings and quality of
service. Competitors also vary project-to-project depending upon the geographic
location of the work to be performed.

             Many competitors are larger than Data Systems and have
significantly greater financial, marketing and human resources, and geographic
coverage. Data Systems believes that it can compete against these competitors on
the basis of its extensive experience in the network integration and management
market, authorization to sell a broad range of products and experienced
technical staff.

EMPLOYEES

             As of December 31, 1999, Data Systems employed 180 persons, 44 were
sales personnel, 118 were service personnel and the remainder were
administrative or management personnel. The Data Systems' employees have no
union affiliations and Data Systems believes its relationship with its employees
is good.


ITEM 2.        PROPERTIES.

             Data Systems' corporate headquarters are located in Farmington
Hills, Michigan, in a leased facility consisting of approximately 12,555 square
feet of office space rented under a lease expiring in November 2002. Data
Systems also leases a technical facility located in Farmington Hills, Michigan
with approximately 7,000 square feet rented under a lease expiring in March
2003. Data Systems also has a telephone "help desk" center located in Baton
Rouge, Louisiana, which is part of its State of Louisiana maintenance contract,
and is located in a facility with 8,200 square feet rented under a lease that
expired in November 1999, and is currently leased on a month-to-month basis.

         Data Systems also leases direct sales offices totaling approximately
25,000 square feet under leases with terms of one to five years, in 10 locations
in the United States. Data Systems believes that its existing facilities and
offices and additional space available to it are adequate to meet its
requirements for its present and reasonably foreseeable needs.

ITEM 3.        LEGAL PROCEEDINGS.

                  On or about October 29, 1998, the Securities and Exchange
Commission ("SEC") informed Data Systems that it was conducting a formal private
investigation of the accounting irregularities experienced by Data Systems in
the fiscal years 1996 and 1997. This inquiry is ongoing, and Data Systems is
cooperating with the investigation.

             On December 9, 1999, Data Systems filed suit against Unified
Network Services, Inc ("UNS") in the State of Michigan, Oakland County Circuit
Court. Effective June 1, 1998, Data Systems sold its interest in the UNS
subsidiary for $7,000 in cash and a note for $3,000,000, secured by the stock of
UNS. The note called for interest only payments to commence July 1, 1998 for a
period of twelve months followed by monthly payments of $50,000 plus interest on
the unpaid balance until the note is fully repaid at June 1, 2004. Interest was
to accrue on the unpaid balance at a per annum rate equal to the Bank One,
Michigan prime rate. The suit alleges that UNS breached its agreement with Data
Systems by failing and refusing to make payments due on the note. See Item 7
"Year Ended December 31, 1998 Compared to Year Ended December 31, 1997 -
Discontinued Operations".

             On June 16 1998, Data Systems filed suit in Oakland County Circuit
Court, Michigan, against Softech, Inc. alleging that Softech wrongfully retained
monies due Data Systems in accordance with the Asset Purchase Agreement dated
September 12, 1996. In addition, the suit alleged that Softech owed Data Systems
rent under a sublease agreement, had not paid invoices for work completed by
Data Systems and also alleged that software acquired by Data Systems in the
acquisition of the Network Systems Group did not perform properly. The Complaint
alleges fraud, breach of contract, conversion and unjust enrichment (the "Data
Allegations").

             Data Systems' claim was dismissed due to the arbitration provision
in the Asset Purchase Agreement. On November 3, 1998, Softech, Inc. filed a
Demand for Arbitration against Data Systems. Softech alleges that Data Systems
breached the September 12, 1996 Asset Purchase Agreement by failure to register
shares of stock on a timely basis, monies owed for inventory purchases and
receivables, failure to pay for equipment and commissions paid by Softech on
behalf of Data Systems, commissions owed to employees of Softech, advances to
former employees who became employees of Data Systems and rents. Data Systems
filed a counter claim with respect to the Data Allegations in connection with
the arbitration. The arbitration hearing is scheduled for June 2000 and Data
Systems intends to pursue its counter claim and vigorously defend itself against
Softech's claims.


             Other than the above, Data Systems is not party to any other legal
proceedings other than routine legal matters arising in the normal course of
business, which management believes will not be material to Data Systems'
financial condition or operations.

               MATTERS

  As of December 31, 1999 Data Systems' Common Stock was traded on the
Over-the-Counter Bulletin Board ("OTCBB") under the symbol "DSYS." During 1998,
Data Systems was also listed on the Nasdaq SmallCap Market (symbol "DSYS") and
on the Pacific Stock Exchange ("PSE") under the symbol "DSY." Due to late SEC
filings and other related issues experienced during the first two quarters of
1998, Data Systems was de-listed from Nasdaq and the PSE. The high and low sales
prices for the Common Stock on the Nasdaq SmallCap Market and the OTC Bulletin
Board during the period from January 1, 1998 through December 31, 1999 are set

                  Data Systems has never declared or paid any dividends on its
capital stock. Data Systems does not anticipate paying any cash dividends in the
foreseeable future. Future cash dividends, if any, will be at the discretion of
the Data Systems' Board of Directors and will depend upon, among other things,
Data Systems' future earnings, operations, capital requirements and surplus,
general financial condition, contractual restrictions, and such other factors as
the Board of Directors may deem relevant. Data Systems' primary lender, Foothill
Capital Corporation, must also approve any dividend distribution.

ITEM 7.        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
               RESULTS OF OPERATIONS

The following discussion and analysis compares the financial results for the
three-year period ending December 31, 1999 and should be read in conjunction
with Data Systems' financial statements and notes thereto.

               The following discussion and analysis contain a number of
"forward looking statements" within the meaning of the Securities Exchange Act
of 1934 and are subject to a number of risks and uncertainties. These risks may
include the continuation of current favorable economic conditions, the ability
of Data Systems' customers to fulfill contractual commitments, the ability of
Data Systems to recruit and retain qualified personnel, the ability of Data
Systems to develop and sustain new customers, the willingness of Data Systems'
bank lender to continue to lend under its current credit facility or Data
Systems' ability to secure alternative working capital financing, the relative
uncertainties in the market direction of emerging technologies, the potential
loss of key personnel, Data Systems' ability to retain its commercial and
governmental contracts, the potential lack of market acceptance of Data Systems'
products and services, and certain risks associated with the closing of the
merger between Data Systems and TekInsight.

                              RESULTS OF OPERATIONS

        For the periods indicated, the following table sets forth selected items

                    COMPARED TO YEAR ENDED DECEMBER 31, 1998

REVENUES.

         Data Systems' total revenues declined to $52.8 million in 1999,
compared to $85.3 million in 1998. The decline (38.1%) is the cumulative effect
of the termination of a specific product sales contract, non-recurring product
project work and a change in sales strategy to an emphasis on service sales.

         The Data Systems' product sales component of the business declined to
$32.4 million in 1999 from $63.5 million in 1998 due primarily to the completion
and expiration on September 30, 1998, of Data Systems' master contractor
purchase order with the State of Michigan. Product sales to the State of
Michigan were made under that agreement and accounted for $17.1 million in sales
in 1998. The State of Michigan continues to buy network services and service
maintenance contracts from Data Systems. Non-recurring product project work
completed in 1998 for Hooper Homes and the State of Louisiana accounted for $4.7
million and $3.1 million, respectively, of the decline in product revenues from
1998 to 1999.

          In prior periods, Data Systems would sell equipment and absorb the
full burden of financing those sales. During 1999, Data Systems worked with key
vendors to pass-through hardware sales directly to the customer. This allows the
vendor to absorb the risk and burden of financing the equipment component of the
sale. As a result, Data Systems recognized a commission on the sale without the
risk and cost associated with carrying a receivable for equipment sales. This
change was implemented as part of Data Systems' strategic move towards service
sales with less emphasis on the hardware component of its business. The change
implemented by Data Systems of equipment sales pass -through to the vendors
accounted for approximately $10.9 million of the product revenue decline from
1998 to 1999. Data Systems' shift in emphasis to service sales from product
sales is due to the expectation of higher margins generally associated with
sales of technical services.

         Service revenues declined 6.4% to $20.4 million in 1999 from $21.8
million in 1998. The decline is due to the loss of the service revenue
associated with the State of Michigan master product purchase order, which
expired September 30, 1998, and the termination of unprofitable imaging
services. Service sales accounted for 38.6% of total revenue in 1999 versus
25.5% in 1998. This percentage increase was due to the overall decline in
product revenue as described above.

<PAGE>   12

COST OF REVENUES.

                The decline in cost of revenues in 1999 is consistent with the
reduction in product sales due to the termination of the Sate of Michigan master
contractor purchase order, non-recurring product project work and Data Systems'
success with involving key vendors in the financing of large equipment sales. In
addition, Data Systems continues to manage external labor costs, increase
internal technical workforce utilization and increase high-end network service
work. Primarily as a result of this activity, cost of revenues decreased to
81.1% of total revenues in 1999 from 83.5% of total revenues in 1998.

                Cost of product revenue decreased as a percentage of total
revenues to 50.4% in 1999 from 61.2% in 1998. The decline in product revenue and
the ability to pass through product sales accounts for the reduction in the cost
of product revenue. Product revenue gross margins increased to 18.0% in 1999
versus 17.8% in 1998.

                Cost of service revenue increased to 30.7% of total revenues in
1999 from 22.3% of total revenues in 1998 due to the decrease in overall sales.
However, service revenue gross margins increased to 20.6% in 1999 versus 12.7%
in 1998 due to Data Systems' management of external labor while increasing the
utilization of the internal technical workforce.

                Overall, gross profit in 1999 decreased $4.1 million, or 29.0%,
from 1998. However, gross margin as a percent of revenue increased in 1999 to
18.9%, versus 16.5% in 1998. The increase in margin is attributable to Data
Systems' ability to negotiate vendor discounts for product purchases, vendor
financing of large equipment transactions and increases in service margins as
described above.

OPERATING EXPENSES.

                Operating expenses increased to 20.4% of total revenues in 1999
from 18.0% of total revenues in 1998. Sales expenses remained constant at 11.6%
of total revenues in 1999 and 1998 respectively. General and administrative
expense increased to 8.8% of total revenues in 1999 from 6.4% of total revenues
in 1998. The increase in operating expense margin is directly related to the
decrease in total revenue. However, overall operating expenses declined 29.8%
due to cost controls and overhead reductions put in place during 1999.
Specifically, sales offices in Chicago, Ill, Raleigh, NC, and Lexington, KY were
closed and administrative positions were consolidated through attrition, without
jeopardizing controls or procedures. Included in 1999, are non-recurring
expenses for professional fees and unprofitable operations as a result of Data
Systems operating under the terms of the merger agreement with Information
Architects that was terminated on September 15, 1999. The differential between
1998 and 1999 was impacted by the fact that 1998 included some non-recurring
costs required to complete Data Systems' year-end audits for 1997 and 1996
reporting, costs associated to Data Systems' shareholder class action lawsuit,
and bank audit and examination expenses.

OTHER INCOME (EXPENSES).

                Other income for 1999 increased $3,397,373 to $978,252
and was primarily attributable to the settlement of Data Systems' shareholder
class action lawsuit. Data Systems established an accrual in 1998 of
approximately $1.8 million for the estimated fair market value of the shares of
Data Systems' common stock that were to be contributed into the gross settlement
fund for the suit. At the time of settlement (June 22, 1999), Data Systems
recognized as income approximately $1.1 million of the accrual because the
actual fair market value of the common stock issued was $630,500. The remaining
change was due to Data Systems' reversal of certain accrued costs offset by a
loss on sale of non-revenue producing assets. The disposal of the assets was
related to the closure of three sales offices.

                Interest expense decreased $.2 million due primarily to Data
Systems' success at negotiating more advantageous payment terms with its key
vendors and overall reductions in Data Systems' bank borrowings.

                    COMPARED TO YEAR ENDED DECEMBER 31, 1997

         Data Systems' total revenues declined slightly to $85.3 million in
1998, compared to $86.0 million in 1997. The decline (0.8%) was due to the net
effect of the termination of a specific product sales contract offset by Data
Systems' organic growth in service sales and in the eastern region of the United
States.

         Data Systems' product sales component of the business declined to $63.5
million in 1998 from $67.8 million in 1997 due primarily to the completion and
expiration on September 30, 1998, of Data Systems' master contractor purchase
order with the State of Michigan. Product sales to the State were made under
that agreement. The State continues to buy network services and service
maintenance contracts from Data Systems. Of the $4.3 million decline in product
sales, approximately $3.8 was attributed to the completion of the State of
Michigan agreement. The remainder of the decline in product sales was due to
management's continued focus on new account penetration through the offering of
advanced services, including network management services. Data Systems' shift in
emphasis to service sales from product sales was due to the expectation of high
margins generally associated with sales of technical services.

         Service revenues increased 20.4% to $21.8 million in 1998 from $18.1
million in 1997. Service sales accounted for 25.5% of total revenue in 1998
versus 21.1% in 1997. This increase was primarily due to the allocation of
additional resources to further develop Data Systems' capabilities to deliver
advanced services.

                The decline in cost of revenues in 1998 was consistent with the
reduction in product sales due to the termination of the Sate of Michigan master
contractor purchase order and the shift to service revenue. Management had
refocused Data Systems' business in conjunction with these changes by shifting
resources away from the lower margin direct product component of revenue, in
favor of the higher returns generated from advanced service and network
management offerings. Primarily as a result of this activity, cost of revenues
decreased to 83.5% of total revenues in 1998 from 85.5% of total revenues in
1997.

                Cost of product revenue decreased as a percentage of total
revenues to 61.2% in 1998 from 68.9% in 1997. Certain software purchases in
support of maintenance contracts were reclassified as cost of services versus
cost of products. This change, along with the decline in product revenue,
accounts for the reduction in the cost of product revenue. Product revenue gross
margins increased to 17.8% in 1998 versus 12.7% in 1997. Data Systems had been
more selective in pricing large projects and believes that the increase in
product gross margin is reflective of the strategic shift away from low margin
sales.

                Cost of service revenue increased to 22.3% of total revenues in
1998 from 16.6% of total revenues in 1997 due to the significant increase in
total service revenues and reclassification of software costs that are more
closely related to service revenue. Additionally, due to Data Systems' decision
to move towards a higher mix of service sales, Data Systems increased its
technical personnel to assist the sales effort with specialized internal
resources. By providing in-house technical resources to support revenue growth,
Data Systems increased expenditures in third party consultants and technicians
to support existing contracts.

                Overall, gross profit increased $1.6 million or 12.9% over 1997.
Gross margin in 1998 was 16.5% versus 14.5% in 1997. To maintain its strategic
direction, emphasizing a shift towards higher margin service sales, Data Systems
did invest resources in technical personnel, hardware, software and processes.

OPERATING EXPENSES.

                Operating expenses decreased to 18.0% of total revenues in 1998
from 18.8% of total revenues in 1997. Sales expenses decreased to 11.6% of total
revenues in 1998 versus 12.0% of total revenues in 1997. General and
administrative expense decreased to 6.4% of total revenues in 1998 from 6.8% of
total revenues in 1997. Overall, operating expenses declined due to cost
controls and overhead reductions put in place during 1998. Specifically, sales
offices in Atlanta, GA, Charlotte, NC, Greensboro, NC, Pittsburgh, PA and
Dallas, TX were closed or consolidated into other more strategically located
offices. Administrative and other overhead reductions were completely offset by
the additional expenditures necessary to address legal and auditing issues. The
non-recurring legal, auditing, and professional fees exceeded just over $1.0
million during 1998. These expenses related to the extraordinary efforts
required to complete Data Systems' year-end 1997 and 1996 reporting, the class
action lawsuits, and bank audit and examination expenses. All totaled, these
matters account for 1.2% of total revenue.

OTHER INCOME (EXPENSES).

                The increase in other expense in 1998 was due primarily to the
recognition of $1.8 million of liability associated with the proposed
stipulation of settlement of Data Systems' shareholder class action lawsuit.
Data Systems established an accrual for the estimated fair market value of the
shares of Data Systems' common stock that will be contributed into the gross
settlement fund. Other expenses, net of the shareholder lawsuit accrual,
declined to $.6 million from $.8 million in 1997. The decrease was due to a $.8
million decrease in interest expense due primarily to Data Systems' success at
negotiating more advantageous payment terms with its key vendors and overall
reductions in Data Systems' bank borrowings.

DISCONTINUED OPERATIONS.

                  Pursuant to the terms of the original 1996 purchase agreement
by which Data Systems acquired UNS, the minority shareholders of UNS elected to
exercise a contract right to initiate re-purchase of the the stock of UNS owned
by Data Systems. Data Systems' Board of Directors accepted the proposal and
adopted a plan to discontinue operations. Effective June 1, 1998, Data Systems
sold its 70% interest in the UNS subsidiary for cash and notes and discontinued
operations in its large account network management business. The terms of the
sale included $7,000 in cash and a note for $3,000,000, secured by the stock of
UNS. The buyers also assumed the existing liabilities of UNS. The gain upon
disposal of the discontinued segment was $705,742 which is net of an allowance
of $3,000,000 due to the uncertainty of the buyers ability to pay the note. Data
Systems deferred the recognition of a gain on sale related to the note until
payments on the note are received. The gain is also net of additional allowances
of $614,000 and $375,000, due to the uncertainty of the buyer's ability to
reimburse Data Systems for working capital and payment of certain assumed
liabilites.

         Data Systems has restated its prior financial statements to present the
operating results of the UNS segment as a discontinued operation.

         On December 9, 1999, Data Systems filed suit against UNS in the State
of Michigan, Oakland County Circuit Court. The suit alleges UNS breached its
agreement with Data Systems by failing and refusing to make payments due on the
note.


FINANCIAL CONDITION

         As of December 31, 1999, cash and investments totaled $1.5 million, a
decrease of $1.1 million from 1998. Cash used in operating activities for 1999
was $3.1 million compared to cash provided by operations of $18.1 million in
1998. The cash used in operating activities was primarily due to a decrease in
accounts payable of $3.3 million, reversal of the Shareholder lawsuit accrual by
$1.1 million and recognition of deferred maintenance revenues of $2.3 million.
These uses were partially offset by income of $191,190 generated in 1999 and
depreciation of $1.1 million and collection of accounts receivable of $2.2
million. Data Systems, in accordance with its bank financing agreement, applies
all available cash to its outstanding line of credit balance. During the year,
Data Systems borrowed $2.0 million against the line of credit. In accordance
with Data Systems' credit agreement with Foothill Capital Corporation, all funds
are applied to the outstanding loan balance. Daily working capital requirements
are managed through daily borrowings.

                                       16

<PAGE>   17

         On September 30, 1998 Data Systems and Foothill Capital Corporation
("Foothill") entered into a credit facility ("Foothill Agreement"). The Foothill
Agreement provides for an initial revolving line of credit not to exceed $15
million. Data Systems may, at its option and subject to certain collateral
requirements, increase the line to $20 million during the term of the Foothill
Agreement. Borrowing limits under the Foothill Agreement are determined based on
a collateral formula, which includes 85% of qualified trade receivables.
Borrowings under the Foothill Agreement bear interest at 1% over Norwest Bank's
prime rate and have a term extending to September 30, 2001. As of December 31,
1999, the line of credit under the Foothill Agreement bore interest at 9.5%. As
of December 31, 1999, the line of credit collateral formula permitted borrowings
of up to $6.2 million, of which $5.2 million was outstanding.

         The Foothill Agreement contains certain financial covenants related to
earnings before interest, taxes, depreciation and amortization ("EBITDA"), net
worth and capital expenditures. There are other covenants that require Data
Systems' receivables to be genuine and free of all other encumbrances and
requires Data Systems' inventory to be kept only at certain locations and to be
free of all other encumbrances. In addition, there are restrictions with respect
to dividend distributions. At December 31, 1999, Data Systems was in compliance
with all of the financial covenants referenced above.

         The Data Systems' working capital deficiency as of December 31, 1999
was $2.2 million. Data Systems believes that the combination of present cash
balances, future operating cash flows, and working capital provided by the
Foothill Agreement or alternate working capital financing secured by Data
Systems will be adequate to fund Data Systems' current short and long term cash
flow requirements. Included in Data Systems' cash is $1.5 million, which is
restricted in connection with various maintenance agreements, "Note A of Notes
to Consolidated Financial Statements".

         Upon completion of its proposed merger with TekInsight.Com, Data
Systems' believes that additional financing resources will be available and
certain synergies relating to business opportunities will arise. See "Note Q of
Notes to Consolidated Financial Statements." However, the Agreement and Plan of
Merger requires Data Systems to conduct business in the usual and ordinary
course but under certain restrictions and limitations. These restrictions and
limitations, in the aggregate, could have an effect on Data Systems' ability to
quickly respond to changes in its business.

YEAR 2000 COMPLIANCE

           The Year 2000 ("Y2K") issue arose as a result of computer programs
using a two-digit format, as opposed to four digits, to indicate the year. The
concern was that computer systems would be unable to interpret dates beyond the
year 1999, which could cause a system failure or other computer errors, leading
to disruptions in operations. In 1997, Data Systems developed a three-phase
program for Y2K information systems compliance. Phase I was to identify those
systems with which Data Systems has exposure to Y2K issues. Phase I was
completed in 1998. Phase II was the development and implementation of action
plans to be Y2K compliant in all areas by mid 1999. Those plans were developed
and implemented as scheduled. Phase III was the final testing of each major area
of exposure to ensure compliance and was completed during the fourth quarter
1999. In implementing its three-phrase program, the Company had identified three
major areas determined to be critical for successful Y2K compliance: (1)
financial and informational system applications, (2) customer relationships and
equipment applications and (3) third-party consultant and vendor relationships.

         Data Systems, in accordance with Phase I of the program, conducted an
internal review and inventory of all systems (including information technology
and non-information technology systems), and contacted all critical suppliers to
determine major areas of exposure to Y2K issues. In the financial and
information system area, a number of applications were identified as Y2K
compliant due to their recent implementation. Data Systems' core financial and
reporting systems were completely replaced as of January 1, 1999, which brought
this critical area into Y2K compliance. In the customer relationships and
equipment applications area, Data Systems completed all remediation and testing
efforts. As a result of its Phase I assessment of its non-information technology
systems, Data Systems did not incur significant costs remediating those systems
for Y2K compliance. In the third-party consultant and vendor relationships area,
Data Systems contacted most of those parties and they stated they were to be Y2K
compliant.

         Data Systems spent approximately $154,000 in 1998 to replace its core
financial and reporting systems and had spent 1,100 man-hours through December
31, 1999 to bring the systems network, financial and informational applications
into Y2K compliance at an estimated cost of $55,000. Because of Data Systems'
expertise in this area, internal personnel undertook the majority of this work.

         Data Systems believes it did not experience any Y2K disruptions due to
the three-phase program it developed and implemented.

         The foregoing disclosure contains information regarding Y2K readiness
that constitutes a "Year 2000 Readiness Disclosure" as defined in the Year 2000
Readiness Disclosure Act.

ITEM 7A        QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

         In the normal course of business, the financial position of Data
Systems is routinely subjected to a variety of risks. In addition to the market
risk associated with interest on outstanding debt, other examples of risk
include collectibility of accounts receivable and recoverability of residual
values of assets placed in service.

         Data Systems' contains an element of market risk due to possible
changes in interest rates. Data Systems regularly assesses these risks and has
established collection policies and business practices to minimize the adverse
effects of these and other potential exposures. Data Systems does not currently
anticipate any material losses in these areas, due primarily to the lack of
significant fluctuation in the prime-lending rate on which Data Systems'
interest expenses are determined. The financial instruments included in the debt
of Data Systems consist of all of Data Systems' cash and cash equivalents, bank
financing, bank credit facilities and lines of credit, vendor credit lines,
leases, and, if applicable, marketable securities, and any short and long-term
investments.

         Data Systems assesses the risk of loss due to the impact of changes in
interest rates on market sensitive instruments. Interest rates effecting Data
Systems' debt are market based and will fluctuate as a result. Data Systems
prepares forecasts and cost of funds analysis on significant purchases to
anticipate the effect of market interest rate changes.

         Data Systems' earnings are affected by changes in short-term interest
rates as a result of its use of bank (line of credit) financing for working
capital. If market interest rates based on the prime lending rate average 2%
more in 2000 than they did during 1999, Data Systems' interest expense, after
considering the effects of interest income, would increase, and income before
taxes would decrease by approximately $.1 million assuming comparable average
borrowings. Comparatively, if market interest rates based on the prime lending
rate averaged 2% more in 1999 than they did in 1998, Data Systems' interest
expense, after considering the effects of any interest income, would have
increased, and income before taxes would have decreased, by $.2 million assuming
comparable average borrowings. These amounts are determined by considering the
impact of the hypothetical change in the interest rates on Data Systems'
borrowing cost and short-term investment balances, if any. These analyses do not
consider the effects of the reduced level of overall economic activity that
could exist in such an environment. Further, in the event of a change of such
magnitude, management would likely take actions to further mitigate its exposure
to the change. However, due to the uncertainty of the specific actions that
would be taken and their possible effects, the sensitivity analysis assumes no
changes in Data Systems financial structure.

               REPORT OF INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS



Board of Directors
Data Systems Network Corporation

We have audited the consolidated balance sheets of Data Systems Network
Corporation and Subsidiaries (a Michigan corporation) as of December 31, 1999
and 1998, and the related statements of operations, stockholders' equity, and
cash flows for the years then ended. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. 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, based on our audits, the financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Data Systems Network Corporation and Subsidiaries as of December 31, 1999 and
December 31, 1998, and the results of operations and cash flows for the years
then ended, in conformity with generally accepted accounting principles.

The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note B to the
financial statements, the Company has suffered recurring losses from operations
and has a deficit in working capital. These matters, among others, as discussed
in Note B to the financial statements, raise substantial doubt about the
Company's ability to continue as a going concern. Management's plans in regard
to these matters are also described in Note B. The financial statements do not
include any adjustments that might result from the outcome of this uncertainty.

We have also audited Schedule II of Data Systems Network Corporation and
Subsidiaries as of and for the year ended December 31, 1999. In our opinion this
schedule presents fairly in all material respects, the information required to
be set forth therein.

NOTE A - NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Data Systems Network Corporation ("Data Systems"), incorporated in Michigan in
1986, provides computer network services and products that allow companies to
control their complex distributed computing environments, allowing companies to
capitalize on their investments in technology and people. Data Systems' wide
range of services includes Applications Development, Network Services,
Enterprise Management, Help Desk and Security Services. Data Systems also
provides a wide range of network integration services including installation,
consultation, technical support and training to governmental and corporate
accounts.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of Data Systems and
its former subsidiary, Unified Network Service, Inc (UNS). The operations of UNS
were sold during 1998 and they are shown as discontinued operations (See Note
C).

CASH EQUIVALENTS

For purposes of the statement of cash flows, Data Systems considers all highly
liquid debt instruments purchased with maturity of three months or less to be
cash equivalents.

RESTRICTED CASH

At December 31, 1999, cash of $1,513,000 was restricted in connection with
maintenance agreements. It will become unrestricted as revenue is recognized
according to the terms of the agreements.

INVENTORIES

Inventories are stated at the lower of cost or market as determined by the
weighted average method. Inventories consist of goods for resale and service
parts, which represent equipment spares utilized for service contracts.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciation and amortization are
computed principally using the straight-line method based upon estimated useful
lives ranging from 5 to 7 years. Amortization of leasehold improvements is
provided over the terms of the various leases.

GOODWILL AND LONG-LIVED ASSETS

The cost in excess of net assets acquired (goodwill) is amortized using the
straight-line method over twenty years, which is the estimate of future periods
to be benefited. Data Systems performs a review for impairment when events or
changes in circumstances indicate that the carrying amount of an asset may not
be recoverable. Undiscounted estimated future cash flows of an asset are
compared with its carrying value, if the cash flows are less than the carrying
value, an impairment loss is recognized.


<PAGE>   28

INCOME TAXES

Income taxes are accounted for by using an asset and liability approach.
Deferred tax assets and liabilities are recognized for the expected future tax
consequences of temporary differences between the financial basis and tax basis
of assets and liabilities. Assets and liabilities are measured using enacted tax
rates expected to apply to taxable income in the years in which those temporary
differences are expected to be recovered or settled.

REVENUE RECOGNITION

Revenue recognition for consulting, network installation services, time and
materials services, and training is recognized when the services are rendered.
Revenue from the sale of merchandise is recognized when the customer receives
the product. Revenue from the sales of after-installation service maintenance
contracts is recognized on a straight-line basis over the lives of the
respective contracts.

PRODUCT RETURNS AND SERVICE ADJUSTMENTS

Product returns and service adjustments are estimated based upon historical
data. Data Systems' customers have no contractual rights to return products.
Data Systems determines whether to accept product returns on a case-by-case
basis and will generally accept product returns only upon payment of a
restocking fee and/or if the products may be returned to the manufacturer. Data
Systems offers no warranty separate from the product manufacturers' warranties.

EARNINGS OR LOSS PER SHARE

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, "Earnings per Share" ("SFAS 128"). SFAS 128 specifies the computation and
presentation and disclosure requirements for earnings per share ("EPS") of
entities with publicly held common stock or potential common stock. SFAS 128
defines two EPS calculations, basic and diluted. The objective of basic EPS is
to measure the performance of an entity over the reporting period by dividing
income available to common stock by the weighted average of shares outstanding.
The objective of diluted EPS is consistent with that of basic EPS while giving
effect to all dilutive potential common shares that were outstanding. For year
ended December 31, 1999, there were no potentially dilutive common shares. For
year ended December 31, 1998, all potential common shares were excluded from the
computation of diluted earnings per share because the effect would have been
anti-dilutive.

USE OF ESTIMATES

The preparation of financial statements in accordance 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.


<PAGE>   29

FAIR VALUE OF FINANCIAL INSTRUMENTS

The carrying amounts of Data Systems' financial instruments consist primarily of
cash and cash equivalents, bank lines of credit, accounts receivables, accounts
payable and short-term and long-term debt, approximate their fair values.

FINANCIAL STATEMENT PRESENTATION

Certain amounts in the 1998 and 1997 financial statements have been reclassified
to conform to the 1999 presentation.


NOTE B - GOING CONCERN

The accompanying financial statements have been prepared on a going concern
basis, which contemplates the realization of assets and the satisfaction of
liabilities in the normal course of business. As shown in the financial
statements, the year ended December 31, 1999 reflected net earnings of
approximately $191,000, however, Data Systems had a loss from operations of
approximately $787,000. During the years ended December 31, 1998 and 1997, Data
Systems incurred losses of $4,678,893 and $4,974,100, respectively. These losses
have contributed to Data System's deficit in working capital of $2,177,185 at
December 31, 1999. These factors, among others, raise substantial doubt about
Data Systems' ability to continue as a going concern. The accompanying financial
statements do not include any adjustments that might result from the outcome of
this uncertainty.

Management's plans with respect to this matter include: continued focus on
reducing operational and overhead costs and the implementation of a change in
strategy to emphasize service sales rather than product sales, which is expected
to increase margins. Management believes the consolidation of its business
operations and the stabilization of strategic business relationships will enable
Data Systems to meet its obligations and attain a level of operations that are
profitable.

In addition, upon completion of the merger with TekInsight.Com (See Note P),
Data Systems believes that additional financial resources will be available and
certain synergies relating to business opportunities will be realized to help
return Data Systems to profitability.

NOTE C - DISCONTINUED OPERATIONS - SALE OF UNIFIED NETWORK SERVICES INC.

During 1998, Data Systems decided to sell its 70% interest in its large account
network management services operation, Unified Network Services Inc. Under the
terms of the original purchase agreement, the minority shareholders of UNS
elected to exercise a contract option to purchase the UNS subsidiary. The terms
of the sale included $7,000 in cash and a note for $3,000,000, which is secured
by the stock of UNS. The buyers also assumed the existing liabilities of UNS.
The gain upon disposal of the discontinued operations is net of allowances of
$3,000,000 due to the uncertainty of the buyer's ability to repay the note and
$989,400 in advances made by Data Systems for working capital, and payment of
certain assumed liabilities.

The results of operations of the discontinued operations for the years ended
December 31, 1998 and 1997 are summarized below:

NOTE G - LINES OF CREDIT

On September 30, 1998 Data Systems and Foothill Capital Corporation ("Foothill")
entered into a credit facility ("Foothill Agreement"). The Foothill Agreement
provides for a revolving line of credit not to exceed $15 million. The available
line of credit at December 31,1999 was $644,003. Data Systems may, at its option
and subject to certain collateral requirements, increase the line to $20 million
during the term of the Foothill Agreement. Borrowing limits under the Foothill
Agreement are determined based on a collateral formula, which includes 85% of
qualified trade receivables. Borrowings under the Foothill Agreement bear
interest at 1% over Norwest Bank prime (9.5 % at December 31, 1999) and have a
term extending to September 30, 2001.

Data Systems is required to maintain certain financial ratios. At December 31,
1999 Data Systems was in compliance with all of the ratios required by Foothill
Capital Corporation. In addition, there are restrictions with respect to
dividend distributions.

In connection with the Foothill Agreement, Data Systems issued a warrant for
50,000 shares of common stock with an exercise price not greater than $2.20 per
share. This warrant will expire September 30, 2003.

NOTE J - REDEMPTION OF WARRANTS

During February 1997, Data Systems called all of its outstanding Redeemable
Common Stock Purchase Warrants ("Purchase Warrants") for redemption as of March
10, 1997 pursuant to the Warrant Agreement, dated October 28, 1994, setting
forth the terms of the Purchase Warrants. Approximately 99% of the Warrants were
exercised on or prior to the date of redemption at a price of $6.25 per Warrant,
resulting in net proceeds to Data Systems of approximately $7,400,000. In
connection with the receipt of consent to the redemption Data Systems agreed to
file a registration statement with the Securities and Exchange Commission with
respect to 60,000 units, issued to the underwriters' representatives in Data
Systems' initial public offering, consisting of two common shares and two
warrants to purchase an additional two common shares which may be purchased upon
exercise of a warrant. The exercise price of these warrants was reduced from
$16.50 to $12.50 per unit and the exercise price of the purchase warrants was
reduced from $10.3125 to $6.25 per unit. The registration was completed in July
1997 and during the third quarter of 1997, all related warrants were exercised,
resulting in net proceeds to Data Systems of approximately $1,400,000.

NOTE K - STOCK OPTION PLANS

In April 1994 Data Systems adopted the 1994 Stock Option Plan ("the Plan"). A
total of 200,000 shares were reserved for issuance under the plan. The options
vest over a two-year period at the rate of 50% per year, beginning on the first
anniversary of the grant date. In April 1997, Data Systems amended the Plan to
increase the reserved shares to 600,000. The vesting period in Data Systems'
form option grant agreement was also changed to 50% on the second anniversary of
the grant date and 25% on each of the third and fourth anniversaries of the
grant date. Data Systems' Compensation Committee retains the ability to change
the vesting schedule at any time.

In 1999 Data Systems granted options for 50,000 shares to a Director of Data
Systems exercisable at a price of $.66 per share when the fair market value at
the date of the grant was $1.03. Such options vest 50% on the second anniversary
date, and the 25% vest each of the next two years. In 1998 and 1997, Data
Systems granted options for 40,000 and 3,000, shares, respectively, exercisable
at a price of $.88 and $9.83 per share, respectively, which was the fair market
value at the date of grant, to Directors of Data Systems. Such options vest one
year from the grant date.


<PAGE>   34

The per share weighted-average fair value of stock options granted during 1999,
1998 and 1997 was $1.03, $3.86 and $9.83 per share, respectively.

As of December 31, 1999, 1998 and 1997 the number of options exercisable was
169,512, 193,123 and 62,461, respectively and the weighted average exercise
price of those options was $5.89, $5.29 and $4.53, respectively.

The Financial Accounting Standard Board has issued Statement No. 123,
"Accounting for Stock Based Compensation" ("SFAS No. 123"). The Statement
established a fair value method of accounting for employee stock options and
similar equity instruments such as warrants, and encourages all companies to
adopt that method of accounting for all of their stock compensation plans.
However, the statement allows companies to continue measuring compensation for
such plans using accounting guidance in place prior to SFAS No. 123. Companies
that elect to remain with the former method of accounting must make pro-forma
disclosures of net earnings and earnings per share as if the fair value method
provided for in SFAS No. 123 had been adopted.


<PAGE>   35
The fair value of each grant is estimated on the date of grant using the
Black-Scholes option - pricing model with the following weighted average
assumptions for grants in 1999: dividend yield of 0%, expected volatility of
136.820%, risk-free interest rate of 6.751% and expected life of ten years.

Data Systems has not adopted the fair value accounting provisions of SFAS No.
123. Accordingly, SFAS No. 123 has no impact on Data Systems' financial position
or results of operations.

Data Systems accounts for the stock option plan under APB Opinion No. 25,
"Accounting for Stock Issued to Employees." No compensation costs have been
recognized. Had compensation cost for the plan been determined based on the fair
value of the options at the grant dates consistent with the method of SFAS No.
123, Data Systems' net earnings (loss) and earnings (loss) per share would have
been as follows (in thousands, except for per share data):

NOTE L - EMPLOYEE BENEFIT PLANS

Data Systems maintains a defined contribution 401(k) plan that covers
substantially all employees. Contributions to the Plan may be made by Data
Systems (which are discretionary) or by plan participants through elective
salary reductions. No contributions were made to the plan by Data Systems during
the years ended December 31, 1999, 1998, and 1997.


NOTE M - MAJOR CUSTOMERS

In 1998 and 1997, the State of Michigan accounted for approximately 29% of
revenue in each year. Additionally, the State of New York represented 25% and
12% of total revenues for 1999 and 1998 respectively.

NOTE N -COMMITMENTS AND CONTINGENCIES

Data Systems is involved in certain routine legal proceedings which are
incidental to its business. All of these proceedings arose in the ordinary
course of Data Systems' business and, in the opinion of Data Systems, any
potential liability of Data Systems with respect to these legal actions will
not, in the aggregate, be material to Data Systems' financial condition or
operations.

NOTE O - SETTLEMENT OF LAWSUIT

On February 17, 1999, Data Systems announced that it had agreed to a stipulation
of settlement of the consolidated complaint in the shareholder class action
lawsuit captioned, In Re: Data Systems Network Corporation Securities
Litigation, Case No. 98-70854. The stipulation of settlement has been filed in
federal court in Detroit, Michigan and the court determined the settlement to be
fair on May 24, 1999.. Under the terms of the settlement, and subject to various
conditions, Data Systems created a gross settlement fund. The fund benefits a
settlement class of purchasers who bought Data Systems' stock during the period
from May 16, 1996 through February 24, 1998. The fund was comprised of $900,000
provided by Data Systems' insurer, and, 650,000 shares of Data Systems' common
stock which were issued June 22, 1999. In agreeing to the settlement, Data
Systems and individual defendants made no admission of any wrongdoing.

As of December 31, 1998, Data Systems recorded a liability for this settlement
in the amount of $ 1,768,000. The amount of the liability was calculated
assuming that a proposed merger with Information Architects had taken place and
that the shares to be issued were those of Information Architects.

When the plan of merger with Information Architects did not take place as
planned the shares issued in the settlement were those of Data Systems rather
than Information Architects. As a result, the amount of the settlement of the
lawsuit was less than anticipated at December 31, 1998 and Data Systems
recognized $ 1,137,500 as income in 1999.



NOTE P - SUBSEQUENT EVENT

On January 18, 2000, Data Systems signed a letter of intent with TekInsight.Com,
Inc. (Teks). Pursuant to the letter of intent, Data Systems agreed to enter into
a proposed acquisition transaction calling for Data Systems to be merged into
Astratek, Inc., a wholly owned and principal operating subsidiary of Teks (the
"Merger"). In consideration for the merger, Data Systems' shareholders will
receive a number of shares of a new class of Teks convertible Preferred Stock
(convertible into Teks common stock on a one to one basis) proposed to be listed
on the NasdaqSmall Cap market that will have a market value of between
$12,500,000 and $18,000,000, with such value to be based upon the market price
of Teks Common stock at the time of closing. Although no assurances can be
given, the parties intend to close the Merger by June 30, 2000.

On February 18, 2000, Data Systems and TekInsight.Com, Inc. ("TekInsight")
entered into an Agreement and Plan of Merger pursuant to which Data Systems will
be merged (the "Merger") into Astratek, Inc., a wholly owned and operating
subsidiary of TekInsight. In consideration for the Merger, Data Systems'
shareholders will receive a varying purchase price (the "Merger Price") which
will equal $12,500,000 if the market price of Tekinsight's common stock at the
time of closing (the "Market Price") is less than $5.00 per share, $16,000,000
if the Market Price is between $5.00 and $7.00 per share, and $18,000,000 if the
Market Price is over $7.00 per share. The Merger Price will be delivered to Data
Systems' shareholders through a distribution of a number of a new class of
TekInsight convertible preferred stock proposed to be listed on the Nasdaq Small
Cap market, with the number of such shares to be found by dividing the
applicable Merger Price by the Market Price. Completion of the Merger is subject
to a number of conditions, including receipt of TekInsight and Data Systems
shareholder approval, acceptance by Nasdaq for the listing of the convertible
preferred stock and other customary closing conditions. There can be no
assurance the Nasdaq listing will be obtained for the newly issued convertible
preferred stock, or that any of the closing conditions will be satisfied.
Although no assurances can be given, the parties intend to close the merger no
later than June 30, 2000.

ITEM 9. CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND
        FINANCIAL DISCLOSURE

         On October 15, 1998, Plante & Moran, LLP ("Plante") informed the Board
  of Directors of Data Systems that it would decline to stand for reappointment,
  if asked, as auditors for Data Systems. Plante also notified Data Systems at
  that time that, as of the date of such notification, the client-auditor
  relationship between the parties was terminated. Data Systems placed no
  limitations on Plante responding fully to inquiries of the successor
  accountant.

         The reports of Plante on Data Systems financial statements for each of
  the fiscal years ended December 31, 1997 and 1996 contained no adverse opinion
  or disclaimer of opinion and were not qualified or modified as to uncertainty,
  audit scope or accounting principle, except that, as issued, Plante's report
  dated August 20, 1998 included a modification addressing Data Systems' going
  concern uncertainty. The Data Systems' plans concerning these matters are
  described in the footnotes attached to the financial statement referenced in
  that report.

         In connection with its audits for the fiscal years December 31, 1997and
  1996, and through October 15, 1998, (i) there were no disagreements between
  Data Systems and Plante on any matter of accounting principles or practices,
  financial statement disclosure, or auditing scope or procedure, which
  disagreements if not resolved to the satisfaction of Plante would have caused
  them to make reference thereto in their report on the financial statement for
  such fiscal years and (ii) there were no reportable events as defined in
  Regulation S-K Item 304(a)(1)(v) except that Plante advised the Audit
  Committee of Data Systems' Board of Directors, by letter dated May 21, 1998,
  of certain items it considered to be material weaknesses in internal controls
  in 1997 relating to Data Systems' general accounting practices then in place,
  including those relating to billing, accounts payable, and inventory. These
  items were discussed with the Audit Committee on September 15, 1998.
  Management has addressed and will continue to address the recommendations of
  Plante.

         SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

        Section 16(a) of the Securities Exchange Act of 1934 requires Data
Systems' officers and directors, and persons who own more than 10% of a
registered class of Data Systems' equity securities, to file reports of
ownership and changes in ownership with the Securities and Exchange Commission.
Officers, directors and greater than 10% shareholders are required by SEC
regulation to furnish Data Systems with copies of all Section 16(a) forms they
file. Based solely on its review of the copies of such forms received by it
since January 1, 1999, or written representations from certain reporting persons
that no Forms 5 were required for those persons, Data Systems believes that its
officers, directors, and greater than 10% beneficial owners filed all reports

(a)      Value was determined by multiplying the number of shares subject to the
         option by the difference between the last sale price of the Common
         Stock reported for December 31, 1999 on the Over-the-Counter Bulletin
         Board and the option exercise price.

DIRECTOR COMPENSATION

         Customarily, Data Systems has paid non-employee directors an annual
retainer of $1,000 and a fee of $500 for each Board or committee meeting
attended. On the date of each annual shareholders meeting, each non-employee
director elected or reelected as such will also receive an option under the 1994
Stock Option Plan to purchase 1,000 shares of Common Stock, exercisable
beginning one year after the grant date, at an exercise price equal to the fair
market value on the grant date. Data Systems also reimburses out-of-pocket
expenses related to non-employee directors in attendance at such meetings.

         Data Systems did not hold an annual shareholder meeting in 1999. During
1999 Data Systems did not pay the Directors for their services. However, in
order to compensate the Board for their services to Data Systems, it was
resolved that the Board members would receive shares of Data Systems' stock in
lieu of cash. The compensation is $2,000 per month in value of common stock
