                               INDEMNITY AGREEMENT

                  THIS INDEMNITY AGREEMENT, dated as of April 3, 2000 is made by
and between TekInsight.Com, Inc., a Delaware corporation having an address at 5
Hanover Square, New York, NY 10004 (the "Company"), and [ ], an individual
residing at [ ] (the "Indemnitee").

                                R E C I T A L S :

         A. The Company recognizes that competent and experienced persons are
increasingly reluctant to serve as directors and officers of corporation unless
they are protected by comprehensive liability insurance or indemnification, or
both, due to increased exposure to litigation costs and risks resulting from
their service to such corporations, and due to the fact that the exposure
frequently bears no reasonable relationship to the compensation of such
directors and officers;

         B. The statutes and judicial decisions regarding the duties of
directors and officers are often difficult to apply, ambiguous or conflicting,
and therefore fail to provide such directors and officers with adequate,
reliable knowledge of legal risks to which they are exposed or information
regarding the proper course of action to take;

         C. The Company and Indemnitee recognize that plaintiffs often seek
damages in such large amounts and the costs of litigation may be so enormous
(whether or not the case is meritorious), that the defense and/or settlement of
such litigation is often beyond the personal resources of officers and
directors;

         D. The Company believes that it is unfair for its directors and
officers and those serving other entities at the request of the Company to
assume the risk of huge judgments and other expenses which may occur in cases in
which the director or officer received no personal profit and in cases where the
director or officer acted in good faith;

         E. The Delaware General Corporation Law (the "DGCL"), under which the
Company is organized, empowers the Company to indemnify its officers, directors,
employees and agents by agreement and to indemnify persons who serve, at the
request of the Company, as the directors, officers, employees or agents of other
corporations or enterprises, and expressly provides that the indemnification
provisions of the DGCL are not exclusive;

         F. The Board of Directors has determined that contractual
indemnification as set forth herein is not only reasonable and prudent but
necessary to promote the best interests of the Company and its stockholders;

         G. The Company has requested the Indemnitee to serve or continue to
serve the Company free from undue concern for claims for damages arising out of
or related to such services to the Company;

         NOW, THEREFORE, in consideration of the mutual covenants and agreements
set forth below, the parties hereto, intending to be legally bound, hereby agree
as follows:

         1. Definitions.

             (a) Affiliate(s). Means any affiliate, subsidiary or other entity
         similarly related to Company.

             (b) Company. For purposes of this Agreement, "Company" shall
         include TekInsight.Com, Inc., as well as all of its Affiliates.

             (c) Expenses. For purposes of this Agreement. "Expenses" includes
         all direct and indirect costs of any type or nature whatsoever
         (including, without limitation, attorneys' fees and related
         disbursements, other out-of-pocket costs and compensation for time
         spent by the Indemnitee for which he or she is not otherwise
         compensated by the Company or any third party), incurred by the
         Indemnitee in connection with either (i) the investigation, defense or
         appeal of or being a witness or otherwise participating or preparing
         for a Proceeding or (ii) the establishment or enforcement of
         Indemnitee's right to indemnification under this Agreement, the DGCL or
         otherwise, including judgments, fines and amounts paid in settlement by
         or on behalf of Indemnitee.

             (d) Proceedings. For the purposes of this Agreement, "Proceeding"
         means any investigation or any threatened, pending or completed action,
         suit or other proceeding, whether civil, criminal, administrative,
         investigative or any other type whatsoever, whether instituted by, or
         in the right of, the Company or by any other person or entity to which
         the Indemnitee was or is a party or a witness or is otherwise involved
         or is threatened to be made a party or a witness or to be otherwise
         involved, by reason of the fact that he is or was a director, officer,
         employee, fiduciary or other agent of the Company, or who is or was
         serving at the request of the Company as a director, officer, employee,
         fiduciary, or agent of another corporation, partnership, joint venture,
         trust or other enterprise of the Company.

             (e) Reviewing Party. For purposes of this Agreement, "Reviewing
         Party" shall be the Special Independent Counsel.

             (f) Special Independent Counsel. For purposes of this Agreement,
         "Special Independent Counsel" shall mean counsel selected by Indemnitee
         and approved by the Company (which approval shall not be unreasonably
         withheld) and who has not, unless waived by the Company and Indemnitee,
         otherwise performed services for the Company or Indemnitee, within the
         last three (3) years. The Company agrees to pay the reasonable fees of
         the Special Independent Counsel referred to above and to fully
         indemnify such counsel against, any and all expenses (including
         attorneys' fees), claims, liabilities and damages arising out of or
         relating to this Agreement or its engagement pursuant hereto.

                                       2

             (g) Voting Securities. For purposes of this Agreement, "Voting
         Securities" shall mean any securities of the Company which vote
         generally in the election of directors.

         2. Agreement to Serve. The Indemnitee has served and agrees to continue
to serve as a member of the board of directors, an officer, employee and/or
consultant, at his will and will serve in such capacities, so long as he is duly
appointed or elected and qualified as such or until such time as he tenders his
resignation in writing.

         3.  Basic Indemnity.

             (a) The Company shall indemnify the Indemnitee if the Indemnitee is
         or was a witness or a party to or is threatened to be made a party to
         or is otherwise involved in any Proceeding brought by any person or
         entity to the fullest extent permitted by law as soon as practicable,
         but in any event no later than ten (10) days after written demand is
         presented to the Company, against any and all Expenses, judgments,
         fines, penalties and amounts paid or owing in settlement (including all
         interest assessments and other charges paid or payable in connection
         with or in respect of such Expenses, judgments, fines, penalties or
         amounts paid in settlement) of such Proceeding.

             (b) Notwithstanding anything in this Agreement to the contrary, (i)
         the obligations of the Company under Section 3(a) shall be subject to
         the condition that the Reviewing Party shall not have determined in a
         writing stating the reasons therefor that Indemnitee would not be
         permitted to be indemnified under applicable law and (ii) the
         obligation of the Company to make an Expense Advance pursuant to
         Section 6 shall be subject to the condition that, if, when and to the
         extent that the Reviewing Party determines that Indemnitee would not be
         permitted to be so indemnified under applicable law, the Company shall
         be entitled to be reimbursed by Indemnitee (who hereby agrees to
         reimburse the Company) for all such amounts theretofore paid; provided,
         however, that if Indemnitee has commenced legal proceedings in a court
         of competent jurisdiction to secure a determination that Indemnitee
         should be indemnified under applicable law, any determination made by
         the Reviewing Party that Indemnitee would not be permitted to be
         indemnified under applicable law shall not be binding and Indemnitee
         shall not be required to reimburse the Company for any Expense Advance
         until such a final judicial determination is made with respect thereto
         (as to which all rights of appeal therefrom have been exhausted or
         lapsed).

             (c) If the Reviewing Party determines that Indemnitee would not be
         permitted to be indemnified in whole or in part under applicable law
         (such determination to be made by the Reviewing Party independent of
         any position of the Company on any aspect of the indemnification
         including but not limited to the appropriateness of the amount of any
         settlement), Indemnitee shall have the right to commence litigation in
         any court, having subject matter jurisdiction thereof, and in which
         venue is proper, seeking an initial determination by the court or
         challenging any such determination by the Reviewing Party or any aspect
         thereof, and the Company hereby consents to service of any process and
         to appear in any such proceeding. Any determination by the Reviewing
         Party otherwise shall be conclusive and binding on the Company and
         Indemnitee.

                                       3

         4. Exceptions. Notwithstanding any other provision of this Agreement,
the Company shall not be obligated pursuant to the terms of this Agreement to
indemnify or make Expense Advances to Indemnitee with respect to any Proceeding
arising out of acts, omissions or transactions for which Indemnitee is
prohibited from receiving indemnification under applicable law.

         5. Partial Indemnity Etc. If Indemnitee is entitled under any provision
of this Agreement to indemnification by the Company for some or a portion of the
Expenses, judgments, fines, penalties and amounts paid in settlement of a
Proceeding but not, however, for all of the total amount thereof, the Company
shall nevertheless indemnify Indemnitee for the portion thereof to which
Indemnitee is entitled. Moreover, notwithstanding any other provision of this
Agreement, to the extent that Indemnitee has been successful on the merits or
otherwise in defense of any Proceeding or in defense of any issue or matter
therein, including dismissal without prejudice, Indemnitee shall be indemnified
against all Expenses incurred in connection therewith. In connection with any
determination by the Reviewing Party as to whether Indemnitee is entitled to be
indemnified hereunder, the burden of proof shall be on the Company to establish
that Indemnitee is not so entitled.

         6. Advancement of Expenses. The Company shall advance all Expenses
incurred by the Indemnitee in connection with the investigation, defense,
settlement or appeal of any Proceeding for which the Indemnitee is entitled to
such advances, and any such advances to be made hereunder shall be paid by the
Company to or on behalf of the Indemnitee within ten (10) days following
delivery of a written demand therefor by the Indemnitee to the Company.

         7. Notice and Other Indemnification Procedures.

             (a) Promptly after receipt by the Indemnitee of notice of the
         commencement, or the threat of commencement, of any Proceeding, the
         Indemnitee shall, if the Indemnitee believes that indemnification with
         respect thereto may be sought from the Company under this Agreement,
         notify the Company of the commencement or threat of commencement
         thereof. The failure to notify the Company shall not affect the
         Company's obligations to indemnify otherwise than under this Agreement.

             (b) In the event the Company shall be obligated hereunder to
         provide indemnification for or make any Expense Advances with respect
         to the Expenses of any Claim, the Company, if appropriate, shall be
         entitled to assume the defense of such Claim upon the delivery to
         Indemnitee of written notice of the Company's election to do so. The
         Company shall keep the Indemnitee and his counsel (which shall be
         retained at the Company's expense) reasonably and currently apprised
         throughout such negotiations and/or defense of the status thereof and
         shall promptly pay the amount of all final judgments and agreed
         settlements, including attorneys' fees and costs. The Indemnitee shall
         cooperate with the Company in all reasonable ways in such negotiations
         and/or defense, but at the sole expense of the Company, and without
         incurring or being deemed to have incurred any obligation or liability
         of any kind, nature or description by reason thereof.

                                       4

             (c) The Company shall indemnify Indemnitee against any and all
         expenses (including attorneys' fees) and, if requested by Indemnitee,
         shall, within ten (10) days of such request, advance such expenses to
         Indemnitee which are incurred by Indemnitee in connection with any
         claim asserted against or action brought by Indemnitee for (i)
         indemnification hereunder or advance payment of Expenses by the Company
         under this Agreement (or any other agreement or the Company's
         Certificate of Incorporation or By-Laws now or hereafter in effect)
         relating to Proceedings and/or (ii) recovery under any director and
         officer liability insurance policies maintained by the Company,
         regardless of whether Indemnitee ultimately is determined to be
         entitled to such indemnification, advance, expense payment or insurance
         recovery, as the case may be.

             (d) For purposes of this Agreement, the termination of any claim,
         action, suit or proceeding by judgment, order, settlement (whether with
         or without court approval) or conviction, or upon a plea of nolo
         contendere, or its equivalent shall not create a presumption that
         Indemnitee did not meet any particular standard of conduct or have any
         particular belief or that a court has determined that indemnification
         is not permitted by applicable law.

         8. Insurance. The Company may, but is not obligated to, obtain
directors' and officers' liability insurance ("D&O Insurance") as may be or
become available with respect to which the Indemnitee is named as an insured.
Notwithstanding any other provision of this Agreement, the Company shall not be
obligated to indemnify the Indemnitee for expenses, judgments, fines or
penalties which have been paid directly to the Indemnitee by D&O Insurance. If
the Company has D&O Insurance in effect at the time the Company receives from
the Indemnitee any notice of the commencement of a Proceeding, the Company shall
give prompt notice of the commencement of such Proceeding to the insurers to
pay, on behalf of the Indemnitee, all amounts payable as a result of such
Proceeding in accordance with the terms of such policy.

         9. Settlement. The Company shall have no obligation under this
Agreement to indemnify the Indemnitee for any amounts paid in settlement of any
Proceeding effected without the Company's prior written consent. The Company
shall not settle any claim in which it takes the position that the Indemnitee is
not entitled to indemnification in connection with such settlement without the
prior written consent of the Indemnitee, nor shall the Company settle any
Proceeding in any manner which would impose any fine or any obligation on the
Indemnitee, without the Indemnitee's prior written consent. Neither the Company
nor the Indemnitee shall unreasonably withhold such consent to any proposed
settlement; provided, however, that the Indemnitee shall not be obligated to
consent to any proposed settlement unless in connection with such settlement the
Indemnitee shall be fully released from all liability with respect to the
relevant Proceeding either because such Proceeding was settled without liability
to the Indemnitee or, if the Indemnitee shall have any liability with respect to
such Proceeding, the Indemnitee shall be fully Indemnified hereunder from all
Expenses resulting from such Proceeding and/or shall receive payment in the
amount of such Expenses pursuant to D&O Insurance.

                                       5
<PAGE>

         10. Nonexclusivity. The provisions for indemnification and advance of
Expenses set forth in this Agreement shall not be deemed exclusive of any other
rights which the Indemnitee may have pursuant to (i) any provision of law, the
Company's Certificate of Incorporation (as amended or restated from time to
time) or Bylaws, (ii) the order or judgment of any court in which a Proceeding
is brought, (iii) the vote of the Company's stockholders or disinterested
directors, or (iv) any other agreements or otherwise, both as to action in his
or her official capacity and to action in another capacity while an Agent of the
Company. The Indemnitee's rights hereunder shall continue after the Indemnitee
has ceased acting as an Agent of the Company and shall inure to the benefit of
the heirs, executors and administrators of the Indemnitee. To the extent that a
change in applicable law (whether by statute or judicial decision) permits
greater indemnification by agreement than would be afforded currently, it is the
intent of the parties hereto that the Indemnitee shall enjoy by this Agreement
the greater benefits afforded by such change.

         11. Subrogation. In the event of payment under this Agreement, the
Company shall be subrogated to the extent of such payment to all of the rights
of recovery of the Indemnitee, who shall execute all papers required and shall
do everything that may be necessary to secure such rights, including the
execution of such documents necessary to enable the Company effectively to bring
suit to enforce such rights.

         12. Termination. No termination of this Agreement shall nullify any of
the rights and obligations of either Indemnitee or the Company hereunder in
respect of any matter occurring prior to the effective date of termination.

         13. Severability. If any provision or provisions of this Agreement
shall be held to be invalid, illegal or unenforceable for any reason whatsoever,
the validity, legality and enforceability of the remaining provisions of the
Agreement (including without limitation, all portions of any paragraphs of this
Agreement containing any such provision held to be invalid, illegal or
unenforceable, that are not themselves invalid, illegal or unenforceable) shall
not in any way be affected or impaired thereby.

         14. Modification and Waiver. No supplement, modification or amendment
of this Agreement shall be binding unless executed in writing by both of the
parties hereto. No waiver of any of the provisions of this Agreement shall be
deemed or shall constitute a waiver of any other provision hereof (whether or
not similar) nor shall such waiver constitute a continuing waiver.

         15. Successors and Assigns. The terms of this Agreement shall bind, and
shall inure to the benefit of, the heirs, administrators, successors (including
any direct or indirect successor by purchase, merger, consolidation or otherwise
to all or substantially all of the business and/or assets of the Company) and
assigns of the parties hereto.

                                       6

a recognized overnight carrier, such as Federal Express; or (iii) if by

counterparts, all of which shall be considered one and the same Agreement.

matter hereof.

                                                                    EXHIBIT 10.2

                               AFFILIATE AGREEMENT

         THIS AFFILIATE AGREEMENT (the "Agreement") is entered into as of this
18th day of February, 2000 by and between TekInsight.Com, Inc. a Delaware
corporation ("Tek"), and the undersigned stockholder ("Stockholder") of DATA
SYSTEMS NETWORK CORPORATION, a Michigan corporation ("DSNC").

         This Agreement is entered into in connection with that certain
Agreement and Plan of Merger, dated as of February 18, 2000 (the "Merger
Agreement"), among Tek, Astratek, Inc., a New York corporation and a
wholly-owned subsidiary of Tek ("Merger Sub"), and DSNC. The Merger Agreement
provides for the merger (the "Merger") of DSNC with and into Merger Sub in a
transaction in which issued and outstanding shares of common stock, $.01 par
value per share, of DSNC (the "DSNC Common Stock") will be converted into shares
of preferred stock, $.0001 par value per share, of Tek (the "Tek Preferred
Stock") on the terms and conditions set forth in the Merger Agreement.
Capitalized terms used herein and not defined herein shall have their defined
meanings as set forth in the Merger Agreement.

         NOW, THEREFORE, in consideration of the foregoing and the mutual
representations, warranties and covenants set forth herein, the parties agree as
follows:

         1. Tax and Accounting Treatment. Each Stockholder understands and
agrees that it is intended that the Merger will be treated as a "reorganization"
for federal income tax purposes. Stockholder further understands and agrees that
Stockholder may be deemed to be an "Affiliate" of DSNC within the meaning of
Rule 145 ("Rule 145") promulgated under the Securities Act of 1933, as amended
(the "Securities Act"), although nothing contained herein should be construed as
an admission of either such fact.

         2. Reliance upon Representations, Warranties and Covenant. Stockholder
has been informed that a reorganization for federal income tax purposes requires
that a sufficient number of former stockholders of DSNC maintain a meaningful
continuing equity ownership interest in Tek after the Merger. Each Stockholder
understands that the representations and warranties and covenants set forth
herein will be relied upon by Tek, DSNC, their respective counsel and accounting
firms and other stockholders of DSNC.

         3. Representations, Warranties and Covenants of each Stockholder. Each
Stockholder represents, warrants and covenants as follows:

                  (a) Such Stockholder has full power and authority to execute
this Agreement, to make the representations, warranties and covenants herein
contained and to perform such Stockholder's obligations hereunder.

                  (b) Appendix A attached hereto sets forth all shares of DSNC
Common Stock owned by such Stockholder, including all DSNC Common Stock as to
which such Stockholder bas sole or shared voting or investment power and all
rights and options to acquire DSNC Common Stock.

<PAGE>

                  (c) Such Stockholder will not sell, transfer, exchange,
pledge, or otherwise dispose of, or make any offer or agreement relating to any
of the foregoing with respect to, any shares of Tek Preferred Stock that such
Stockholder may acquire in connection with the Merger or acquire upon exercise
of any option or right to acquire Tek Preferred Stock, which option or right is
acquired in connection with the Merger, or any securities that may be paid as a
dividend or otherwise distributed thereon or with respect thereto or issued or
delivered in exchange or substitution therefor (all such shares and other
securities of Tek being herein sometimes collectively referred to as "Restricted
Securities"), or any option, right or other interest with respect to any
Restricted Securities, unless (i) such transaction is permitted pursuant to Rule
145(c) and 145(d) under the Securities Act (as described in Section 6 below), or
(ii) counsel representing such Stockholder shall have advised Tek in a written
opinion letter satisfactory to Tek and Tek's legal counsel, and upon which Tek
and its legal counsel may rely, that no registration under the Securities Act
would be required in connection with the proposed sale, transfer or other
disposition, or (iii) a registration statement under the Securities Act covering
the Tek Preferred Stock proposed to be sold, transferred or otherwise disposed
of, describing the manner and terms of the proposed sale, transfer or other
disposition, and containing a current prospectus, shall have been filed with the
SEC and made effective under the Securities Act, or (iv) an authorized
representative of the SEC shall have rendered written advice to such Stockholder
(sought by such Stockholder or counsel to such Stockholder, with a copy thereof
and all other related communications delivered to Tek) to the effect that the
SEC would take no action, or that the staff' of the SEC would not recommend that
the SEC take action, with respect to the proposed disposition if consummated.

                  (d) Notwithstanding any other provision of this Agreement to
the contrary, such Stockholder will not sell, transfer, exchange, pledge or
otherwise dispose of, or in any other way reduce such Stockholder's risk of
ownership or investment in, or make any offer or agreement relating to any of
the foregoing with respect to any DSNC Common Stock or any rights, options or
warrants to purchase DSNC Common Stock, or any Restricted Securities or other
securities of Tek (i) during the 30-day period immediately preceding the
Effective Time of the Merger and (ii) until such time after the Effective Time
of the Merger as Tek has publicly released a report including the combined
financial results of Tek and DSNC for a period of at least 30 days of combined
operations of Tek and DSNC within the meaning of Accounting Series Release No.
130, as amended, of the SEC. Tek agrees to publish such financial results
expeditiously in a manner consistent with its prior practices; provided, that
nothing contained herein shall obligate Tek to publish its financial results
other than on a quarterly basis.

                  (e) Each Stockholder has, and as of the Effective Time of the
Merger will have, no present plan or intention (a "Plan") to sell, transfer,
exchange, pledge (other than in a pre-existing bona fide margin account) or
otherwise dispose of, including a distribution by a partnership to its partners,
or a corporation to its stockholders, or any other transaction which results in
a reduction in the risk of ownership (any of the foregoing, a "Sale") of more

50% of the aggregate fair market value of all shares of outstanding DSNC Common
Stock immediately prior to the Merger. For purposes of the preceding sentence,

rights are exercised, (ii) which are exchanged for cash in lieu of fractional
shares of Tek Preferred Stock or (iii) with respect to which a pre-Merger Sale
occurs in a Related Transaction, shall be considered to be shares of DSNC
Preferred Stock that are exchanged for Tek Preferred Stock in the Merger and
then disposed of pursuant to a Plan. A Sale of Tek Preferred Stock shall be
considered to have occurred pursuant to a Plan if, among other things, such Sale
occurs in a Related Transaction. For purposes of this Section 3(e), a "Related
Transaction" shall mean a transaction that is in contemplation of, or related or

Act"), referred to in paragraph (c)(1) of Rule 144 under the Securities Act, in
order to permit Stockholder to sell the Tek Preferred Stock held by it pursuant
to the terms and conditions of Rule 145 and the applicable provisions of Rule
144. Any future disposition by Stockholder of Tek Preferred Stock will be
accomplished in compliance with all applicable securities laws. Stockholder

other disposition of any Restricted Securities by or on behalf of such
Stockholder or to take any other action necessary in order to make compliance

Rule 145(d)(2) or Rule 145(d)(3) set forth below become available, public
resales of Restricted Securities may only be made by such Stockholder in
compliance with the requirements of Rule 145(d)(1). Rule 145(d)(1) permits such
resales only (i) while Tek meets the public information requirements of Rule
144(c), (ii) in "brokers' transactions" or in transactions with a "market maker"
in accordance with Rule 144(f) and Rule 144(g) and (iii) where the aggregate
number of Restricted Securities sold at any time together with all sales of Tek
Preferred Stock sold for such Stockholder's account during the preceding
three-month period does not exceed the greater of (x) 1% of the Tek Preferred
Stock outstanding, (y) the average weekly volume of trading in Tek Preferred
Stock on all national securities exchanges and/or reported through the automated
quotation system of a registered securities association during the four calendar
weeks preceding the date of receipt of the order to execute the sale or (z) the
average weekly volume of trading in Tek Preferred Stock reported through the

Exchange Act during the four-week period specified in subsection (y) above.

                  (b) Each Stockholder may make unrestricted resales of
Restricted Securities pursuant to Rule 145(d)(2) if (i) such Stockholder has
beneficially owned (within the meaning of Rule 144(d) under the Securities Act)
the Restricted Securities for at least one year after the Effective Time of the
Merger, (ii) such Stockholder is not an affiliate of Tek and (iii) Tek meets the
public information requirements of Rule 144(c).

                  (c) Each Stockholder may make unrestricted resales of
Restricted Securities pursuant to Rule 145(d)(3) if such Stockholder (i) has
beneficially owned (within the meaning of Rule 144(d) under the Securities Act)
the Restricted Securities for at least two years and (ii) is not and has not
been for at least three months, an affiliate of Tek.

                  (d) Tek acknowledges that the provisions of Section 3(c) of
this Agreement will be satisfied as to any sale by the undersigned of the
Restricted Securities pursuant to Rule 145(d) by delivery to Tek of a broker's
letter and a letter from the undersigned with respect to that sale stating that
each of the above-described requirements of Rule 145(d)(1) has been met or is
inapplicable by virtue of Rule 145(d)(2) or Rule 145(d)(3); provided, that Tek
has no reasonable basis to believe such sales were not made in compliance with
such provisions of Rule 145(d).
