                           INDEMNIFICATION AGREEMENT
                                        
     This Agreement, made and entered into this  __day of February 1998
("Agreement"), by and between Applied Intelligence Group, Inc., an Oklahoma
Corporation ("Corporation"), and  __________"Indemnitee"):

     WHEREAS, recently highly competent persons have become more reluctant to
serve publicly-held corporations as directors, officers, or in other capacities,
unless they are provided with better protection from the risk of claims and
actions against them arising out of their service to and activities on behalf of
such corporations; and

     WHEREAS, the current impracticability of obtaining adequate insurance and
uncertainties related to indemnification have increased the difficulty of
attracting and retaining such persons; and

     WHEREAS, the Board of Directors of the Corporation (the "Board") has
determined that the inability to attract and retain such persons is detrimental
to the best interests of the Corporation's shareholders and that such persons
should be assured that they will have better protection in the future; and

     WHEREAS, it is reasonable, prudent and necessary for the Corporation to
obligate itself contractually to indemnify such persons to the fullest extent
permitted by applicable law, so that such persons will serve or continue to
serve the Corporation free from undue concern that they will not be adequately
indemnified; and

     WHEREAS, this Agreement is a supplement to and in furtherance of Article VI
of the By-laws of the Corporation, any rights granted under the certificate of
incorporation of the Corporation and any resolutions adopted pursuant thereto
shall not be deemed to be a substitute therefor nor to diminish or abrogate any
rights of Indemnitee thereunder; and

     WHEREAS Indemnitee is willing to serve, continue to serve and to take on
additional service for or behalf of the Corporation on the condition that he be
indemnified according to the terms of this Agreement;

     NOW, THEREFORE, in consideration of the premises and the convenants
contained herein, the Corporation and Indemnitee do hereby covenant and agree as
follows:

     Section 1. Definitions. For purposes of this Agreement:
            (a)  "Change in Control" means a change in control of the
                 Corporation of a nature that would be required to be reported
                 in response to Item 6(e) of Schedule 14A-of Regulation 14A (or
                 in response to any similar item on any similar schedule or
                 form) promulgated under the Securities Exchange Act of 1934
                 (the "Act"), whether or not the Corporation is then subject to
                 such reporting requirement; provided, however, that, without
                 limitation, such a Change in Control shall be deemed to have
                 occurred if (i) any "person" (as such term is used in Sections
                 13(d) and 14(d) of the Act) is or becomes the "beneficial
                 owner" (as defined in rule 1 3d-3 under the Act), directly or
                 indirectly, of securities of the Corporation representing 20%
                 or more of the combined voting power of
<PAGE>
 
                 the Corporation's then outstanding securities without the prior
                 approval of at least two-thirds of the members of the Board in
                 office immediately prior to such person attaining such
                 percentage interest; (ii) the Corporation is a party to a
                 merger, consolidation, sale of assets or other reorganization,
                 or a proxy contest, as a consequence of which members of the
                 Board in office immediately prior to such transaction or event
                 constitute less than a majority of the Board thereafter; or
                 (iii) during any period of two consecutive years, individuals
                 who at the beginning of such period constituted the Board
                 (including for this purpose any new director whose election or
                 nomination for election by the Corporation's stockholders was
                 approved by a vote of at least two-thirds of the directors then
                 still in office who were directors at the beginning of such
                 period) cease for any reason to constitute at least a majority
                 of the Board.

            (b)  "Corporate Status" means the status of a person who is or was a
                 director, officer, employee, agent or fiduciary of the
                 Corporation or of any other corporation, partnership, joint
                 venture, trust, employee benefit plan or other enterprise which
                 such person is or was serving at the request of the
                 Corporation.

            (c)  "Disinterested Director" means a director of the Corporation
                 who is not and was not a party to the Proceeding in respect of
                 which indemnification is sought by Indemnitee.

            (d)  "Expenses" means all reasonable attorneys' fees, retainers,
                 court costs, transcript costs, fees of experts, witness fees,
                 travel expenses, duplicating costs, printing and binding costs,
                 telephone charges, postage, delivery service fees, and all
                 other disbursements or expenses of types customarily incurred
                 in connection with prosecuting, defer-ding, preparing to
                 prosecute or defend, investigating, or being or preparing to be
                 a witness in a Proceeding.

            (e)  "Independent Counsel" means a law firm, or a member of a law
                 firm, that is for indemnification hereunder. Notwithstanding
                 the foregoing, the term "Independent Counsel" shall not include
                 any person who, under the applicable standards of professional
                 conduct then prevailing, would have a conflict of interest in
                 representing either the Corporation or Indemnitee in an action
                 to determine Indemnitee's rights under this Agreement.

        (f)  "Proceeding" means any action, suit, arbitration, alternate dispute
             resolution mechanism, investigation, administrative hearing or any
             other proceeding, whether civil, criminal, administrative or
             investigative, except one initiated by an Indemnitee pursuant to
             Section 11 of this Agreement to enforce his rights under this
             Agreement.

     Section 2. Services by Indemnitee. Indemnitee agrees to continue to serve
as an officer or director of the Corporation. Indemnitee may at any time and for
any reason resign from such position (subject to any other contractual
obligation or any obligation unposed by operation of law).
<PAGE>
 
     Section 3. Indemnification - General. The Corporation shall indemnify, and
advance Expenses to, Indemnitee as provided in this Agreement to the fullest
extent permitted by applicable law in effect on the date hereof and to such
greater extent as applicable law may thereafter from time to time permit. The
rights of Indemnitee provided under the preceding sentence shall include, but
shall not be limited to, the rights set forth in the other Sections of this
Agreement.

     Section 4. Proceedings Other Than Proceedings by or in the Right of the
Corporation. Indemnitee shall be entitled to the rights of indemnification
provided in this Section if, by reason of his Corporate Status, he is, or is
threatened to be made, a party to any threatened, pending or completed
Proceeding, other than a Proceeding by or in the right of the Corporation.
Pursuant to this Section, Indemnitee shall be indemnified against Expenses,
judgments, penalities, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with any such
Proceeding or any claim, issue or matter therein, if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best interests
of the corporation, and, with respect to any criminal Proceeding, had no
reasonable cause to believe his conduct was unlawful.

    Section 5. Proceedings by or in the Right of the Corporation. Indemnitee
shall be entitled to the rights of indemnification provided in this Section if,
by reason of his Corporate status, he is, or is threatened to be made a party to
any threatened, pending or completed Proceeding brought by or in the right of
the Corporation to procure a judgment in its favor. Pursuant to this Section,
Indemnitee shall be indemnified against Expenses actually and reasonably
incurred by him or on his behalf in connection with any such Proceeding if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Corporation. Notwithstanding the foregoing,
no indemnification against such Expenses shall be made in respect of any claim,
issue or matter in any such Proceeding as to which Indemnitee shall have been
adjudged to be liable to the Corporation if applicable law prohibits such
indemnification unless the District Court of Oklahoma County of the State of
Oklahoma, or the court in which such Proceeding shall have been brought or is
pending, shall determine that indemnification against Expenses may nevertheless
be made by the Corporation.

     Section 6. Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provision of this Agreement, to the extent
that Indemnitee is, by reason of his Corporate Status, a party to and is
successful, on the merits or otherwise, in any Proceeding, he shall be
indemnified against all Expenses actually and reasonably incurred by him or on
his behalf in connection therewith. If Indemnitee is not wholly successful in
such Proceeding but is successful, on the merits or otherwise, as to one or more
but less than all claims, issues or matters in such Proceeding, the Corporation
shall indemnify Indemnitee against all Expenses actually and reasonably incurred
by him or on his behalf in connection with each successfully resolved claim,
issue or matter. For the purposes of this Section and without limiting the
foregoing, the termination of any claim, issue or matter in any such Proceeding
by dismissal, with or without prejudice, shall be deemed to be a successful
result as to such claim, issue or matter.

       Section 7. Indemnification for Expenses of a Witness. Notwithstanding any
other provision of this Agreement, to the extent that Indemnitee is, by reason
of his Corporate Status, a witness in any Proceeding, he shall be indemnified
against all Expenses actually and reasonably incurred by him or on his behalf in
connection therewith.

        Section 8. Advancement of Expenses. The Corporation shall advance all
Expenses incurred by or on behalf of Indemnitee in connection with any
Proceeding within twenty days after the receipt by the Corporation of a
statement or statements from Indemnitee requesting such advance or advances 
<PAGE>
 
from time to time, whether prior to or after final disposition of such
Proceeding. Such statement or statements shall reasonably evidence the Expenses
incurred by Indemnitee and shall include or be preceded or accompanied by an
undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it
shall ultimately be determined that Indemnitee is not entitled to be indemnified
against such Expenses.

     Section 9. Procedure for Determination of Entitlement to Indemnification.

     (a) To obtain indemnification under this Agreement in connection with any
     Proceeding, and for the duration thereof, Indemnitee shall submit to the
     Corporation a written request, including therein or therewith such
     documentation and information as is reasonably available to Indemnitee and
     is reasonably necessary to determine whether and to what extent Indemnitee
     is entitled to indemnification. The Secretary of the Corporation shall,
     promptly upon receipt of any such request for indemnification, advise the
     Board in writing that Indemnitee has requested indemnification.

     (b) Upon written request by Indemnitee for indemnification pursuant to
     Section 9(a) hereof, a determination, if required by applicable law, with
     respect to Indemnitee's entitlement thereto shall be made in such case: (i)
     if a Change in Control shall have occurred, by Independent Counsel (unless
     Indemnitee shall request that such determination be made by the Board or
     the shareholders, in which case in the manner provided for in clauses (ii)
     or (iii) of this Section 9(b)) in a written opinion to the Board, a copy of
     which shall be delivered to Indemnitee; (ii) if a Change in Control shall
     not have occurred, (A) by the Board by a majority vote of a quorum
     consisting of Disinterested Directors, or (B) if a quorum of the Board
     consisting of Disinterested Directors is not obtainable, or even if such
     quorum is obtainable, if such quorum of Disinterested Directors so directs,
     either (x) by Independent Counsel in a written opinion to the Board, a copy
     of which shall be delivered to Indemnitee, or ((y)) by the shareholders of
     the Corporation as determined by such quorum of Disinterested Directors, or
     a quorum of the Board, as the case may be; or (iii) as provided in Section
     10(b)) of this Agreement. If it is so determined that Indemnitee is
     entitled to indemnification, payment to Indemnitee shall be made within ten
     (10) days after such determination. Indemnitee shall cooperate with the
     person, persons or entity making such determination with respect to
     Indemnitee's entitlement to indemnification, including providing to such
     person, persons or entity upon reasonable advance request any documentation
     or information which is not privileged or otherwise protected for
     disclosure-and which is reasonably available to Indemnitee and reasonably
     necessary to such determination. Any costs or expenses (including
     attorneys' fees and disbursements) incurred by Indemnitee in so cooperating
     with the person, persons or entity making such determination shall be borne
     by the Corporation (irrespective of the indemnification) and the
     Corporation hereby indemnifies and agrees to hold Indemnitee harmless
     therefrom.

     (c) If required, Independent Counsel shall be selected as follows: (i) if a
     Change in Control shall not have occurred, Independent Counsel shall be
     selected by the Board, and the Corporation shall give written notice to
     Indemnitee advising him of the identity of Independent Counsel so selected;
     or (ii) if a Change in Control shall have occurred, Independent Counsel
     shall be selected by Indemnitee (unless Indemnitee shall request that such
     selection be made by the Board, in which event (I) shall apply), and
     Indemnitee shall give written notice to the Corporation advising it of the
     identity of Independent Counsel so selected. In either event, Indemnitee or
     the Corporation, as the case may be, may, within seven (7) days after such
     written notice of selection shall have been given, deliver to the
     Corporation or to Indemnitee,, as the case may be, a written objection to
     such 
<PAGE>
 
     selection. Such objection may be asserted only on the ground that
     Independent Counsel so selected does not meet the requirements of
     "Independent Counsel" as defined in Section 1 of this Agreement, and the
     objection shall set forth with particularity the factual basis of such
     assertion. If such written objection is made, Independent Counsel so
     selected may not serve as Independent Counsel unless and until a court has
     determined that such objection is without merit. If, within 20 days after
     submission by Indemnitee of a written request for indemnification pursuant
     to Section 9(a) hereof, no Independent Counsel shall have been selected and
     not objected to, either the Corporation of Indemnitee may petition the
     District Court of Oklahoma County of the State of Oklahoma, or other court
     of competent jurisdiction, for resolution of any objection which shall have
     been made by the Corporation or Indemnitee to the other's selection of
     Independent Counsel and/or for the appointment as Independent Counsel of a
     person selected by such court or by such other person a such court shall
     designate, and the person with respect to whom an objection is so resolved
     or the person so appointed shall act as Independent Counsel under Section
     9(b) hereof. The Corporation shall pay any and all reasonable fees and
     expenses of Independent Counsel incurred by such Independent Counsel in
     connection with its action pursuant to this Agreement, and the Corporation
     shall pay all reasonable fees~and expenses incident to the procedures of
     this Section 9(c), regardless of the manner in which such Independent
     Counsel was selected or appointed. Upon the due commencement date of any
     judicial proceeding or arbitration pursuant to Section l I (a)(iii) of this
     Agreement, Independent Counsel shall be discharged and relieved of any
     further responsibility in such capacity (subject to the applicable
     standards of professional conduct then prevailing).

     Section 10. Presumptions and Effects of Certain Proceedings.

     (a) If a Change in Control shall have occurred, in making a determination
     with respect to entitlement to indemnification hereunder, the person or
     persons or entity making such determination shall presume that Indemnitee
     is entitled to indemnification under this Agreement if Indemnitee has
     submitted a request for indemnification in accordance with Section 9(a) of
     this Agreement, and the Corporation shall have the burden of proof to
     overcome that presumption in connection with the making by any person,
     persons or entity of any determination contrary to that presumption.

     (b) If the person, persons or entity empowered or selected under Section 9
     of this Agreement to determine whether Indemnitee is entitled to
     indemnification shall not have made a determination within sixty (60) days
     after receipt by the Corporation of the request therefor, the requisite
     determination of entitlement to indemnification shall be deemed to have
     been made and Indemnitee shall be entitled to such indemnification, absent
     (i) a misstatement by Indemnitee of a material fact, or an omission of a
     material fact necessary to make Indemnitee's statement not materially
     misleading, in connection with the request for indemnification, or (ii)
     prohibition of such indemnification under applicable law; provided,
     however, that such sixty-day (60-day) period may be extended for a
     reasonable time, not to exceed an additional thirty (30) days, if the
     person, persons or entity making the determination with respect to
     entitlement to indemnification in good faith require(s) such additional
     time for the obtaining or evaluating of documentation and/or information
     relating thereto; and provided, further, that the foregoing provisions of
     this Section 10(b) shall not apply (i) if the determination of entitlement
     to indemnification is to be made by the shareholders pursuant to Section
     9(b) of 
<PAGE>
 
     this Agreement and if (A) within fifteen (15) days after receipt by the
     Corporation of the request for such determination the Board has resolved to
     submit such determination to the shareholders for their consideration at an
     annual meeting thereof to be held within seventy-five (75) days after such
     receipt and such determination is-made thereat, or (B) a special meeting of
     shareholders is called within fifteen ((15) days after such receipt for the
     purpose of making such determination, such meeting is held for such purpose
     within sixty (60) days after having been so called and such determination
     is made thereat, or (ii) if the determination of entitlement to
     indemnification is to be made by Independent Counsel pursuant to Section
     9(b) of this Agreement.

     (c) The termination of any Proceeding or of any claim, issue or matter
     therein, by judgment, order settlement or conviction, or upon a plea of
     nolo contendere or its equivalent, shall not (except as otherwise expressly
     provided in this Agreement) of itself adversely affect the right of
     Indemnitee to indemnification or create a presumption that Indemnitee did
     not act in good faith and in a manner which he reasonably believed to be in
     or not opposed to the best interests of the Corporation or, with respect to
     any criminal Proceeding, that Indemnitee had reasonable cause to believe
     that his conduct was unlawful.

     Section 11. Remedies of Indemnitee.

     (a) In the event that (i) a determination is made pursuant to Section 9 of
     this Agreement that Indemnitee is not entitled to indemnification under
     this Agreement, (ii) advancement of Expenses is not timely made pursuant to
     Section 8 of this Agreement, (iii) the determination of entitlement to
     indemnification is to be made by Independent Counsel pursuant to Section
     9(b) of this Agreement and such determination shall not have been made and
     delivered in a written opinion within ninety (90) days after receipt by the
     Corporation of the request for indemnification, (iv) payment of
     indemnification is not made pursuant to section 7 of this Agreement within
     ten (10) days after receipt by the Corporation of a written request
     therefor, or (v) payment of indemnification is not made within ten (10)
     days after a determination has been made that Indemnitee is entitled to
     indemnification or such determination is deemed to have been made pursuant
     to Section 9 or 10 of this Agreement, Indemnitee shall be entitled to an
     adjudication in an appropriate court of the State of Oklahoma, or in any
     other court of competent jurisdiction, of his entitlement to such
     indemnification or advancement of Expenses. Alternatively, Indemnitee, at
     his option, may seek an award in arbitration to be conducted by a single
     arbitrator pursuant to the rules of the American Arbitration Association.
     Indemnitee shall commence such proceeding seeking an adjudication or an
     award in arbitration within one hundred and eighty (180) days following the
     date on which Indemnitee first has the right to commence such proceeding
     pursuant to this Section 1 l(a). The Corporation shall not oppose
     Indemnitee's right to seek any such adjudication or award in arbitration.

     (b) In the event that a determination shall have been made pursuant to
     Section 9 of this Agreement that Indemnitee is not entitled to
     indemnification, any judicial proceeding or arbitration commenced pursuant
     to this Section 11 shall be conducted in all respects as a de novo trial or
     arbitration on the merits and Indemnitee shall not be prejudiced by reason
     of that adverse determination. If a Change in Control shall have occurred
     in any judicial proceeding or arbitration commenced pursuant to this
     Section 11, the Corporation shall have the burden of proving that
     Indemnitee is not entitled to indemnification or advancement of Expenses,
     as the case may be.

     (c) If a determination shall have been made or deemed to have been made
     pursuant to Section 9 or 10 of this Agreement that Indemnitee is entitled
     to indemnification, the Corporation shall be bound by such determination in
     any judicial proceeding or arbitration commenced pursuant 
<PAGE>
 
     to this Section 11, absent (i) a misstatement by Indemnitee of a material
     fact, or an omission of a material fact necessary to make Indemnitee's
     statement not materially misleading, in connection with the request for
     indemnification, or (ii) prohibition of such indemnification under
     applicable law.

     (d) The Corporation shall be precluded from asserting in any judicial
     proceeding or arbitration commenced pursuant to this Section 11 that the
     procedures and presumptions of this Agreement are not valid, binding and
     enforceable and shall stipulate in any such court or before any such
     arbitrator that the Corporation is bound by all the provisions of this
     Agreement.
            (f)  In the event that Indemnitee, pursuant to this Section 11,
                 seeks judicial adjudication of, or an award in arbitration to
                 enforce, his rights under, or to recover damages for breach of,
                 this Agreement, Indemnitee shall be entitled to recover from
                 the Corporation, and shall be indemnified by the Corporation
                 against, any and all expenses (of the kinds described in the
                 definition of Expenses) actually and reasonably incurred by him
                 in such judicial adjudication or arbitration, but only if he
                 prevails therein. If it shall be determined in such judicial
                 adjudication or arbitration that Indemnitee is entitled to
                 receive part but not all of the indemnification or advancement
                 of expenses sought, the Expenses incurred by Indemnitee in
                 connection with such judicial adjudication or arbitration shall
                 be appropriately prorated.

     Section 12. Non-Exclusivity; Survival of Rights: Insurance: Subrogation.

     (a) The rights of indemnification and to receive advancement of Expenses as
     provided by this Agreement shall not be deemed exclusive of any other
     rights to which Indemnitee may at any time be entitled under applicable
     law, the certificate of incorporation or By-laws of the Corporation, any
     agreement, a vote of shareholders or a resolution of directors, or
     otherwise. No amendment, alteration or repeal of this Agreement or any
     provision hereof shall be effective as to any Indemnitee with respect to
     any action taken or omitted by such Indemnitee with respect to any action
     taken or omitted by such Indemnitee in his Corporate Status prior to such
     amendment, alternation or repeal.

     (b) To the extent that the Corporation maintains an insurance policy or
     policies providing liability insurance for directors, officers, employees,
     agents or fiduciaries of the Corporation or of any other corporation,
     partnership, joint venture, trust, employee benefit plan or other
     enterprise which such person serves at the request of the Corporation,
     Indemnitee shall be covered by such policy or policies in accordance with
     its or their terms to the maximum extent of the coverage available for any
     such director, officer, employee, agent or fiduciary under such policy or
     policies.

     (c)  In the event of any payment under the Agreement, the Corporation shall
          be subrogate to the extent of such payment to all of the rights of
          recovery of Indemnitee, who shall execute all papers required and take
          all action necessary to secure such rights, including execution of
          such documents as are necessary to enable the Corporation to bring
          suit to enforce such rights.

     (d)  The Corporation shall not be liable under this Agreement to make any
          payment of amounts otherwise indemnifiable hereunder if and to the
          extent that Indemnitee has otherwise actually received such payment
          under any insurnace policy, contract, agreement or otherwise.

     Section 13. Duration of Agreement. This Agreement shall continue until and
     terminate under the later of:

     (a) Ten (10) years after the date that Indemnitee shall have ceased to
     serve as a director, 
<PAGE>
 
     officer, employee, agent or fiduciary of the Corporation or of any other
     corporation, partnership, joint venture, trust, employee benefit plan or
