                              AMENDED AND RESTATED
                          SELLING SHAREHOLDER AGREEMENT

          THIS AMENDED AND RESTATED SELLING SHAREHOLDER AGREEMENT (this
"Agreement") is made and enter into on the effective date of 7th day of
February, 2002 by and among Paul A. Kruger, Randel T. Dunn, John F. Luther,
Billy Rhodes Trustee of Rhodes Family Trust, Mary L. Kelly, and Leland S.
Chaffin, Jr. (collectively, "Selling Shareholders" or singly, "Selling
Shareholder"), Judith H. Henkels ("Judith"), Mary L. Kelly ("Mary"), and Precis,
Inc., an Oklahoma corporation ("Precis").

                                    RECITALS

          1. The Selling Shareholders in the aggregate intend to offer for sale
and sell 2,500,000 shares of Precis common stock, $0.01 pare value per share
("Common Stock") through Stonegate Securities, Inc. ("Stonegate") pursuant to
registration under the Securities Act of 1933, as amended (the "1933 Act") (such
offer to sell and sale is referred to as the "Public Offering"). The 2,500,000
shares of Common Stock will be offered in two groups, the first to be 1,333,000
shares ("Primary Shares") and 1,167,000 shares ("Secondary Shares"). For
purposes of this Agreement, Primary Shares and Secondary Shares are collectively
referred to as the "Shares."

          2. Each Selling Shareholder intends to offer for sale pursuant to the
Public Offering the number of Primary Shares and Secondary Shares set forth
opposite each Selling Shareholder's name as follows:

</Table>

          3. Pursuant to the agreement amongst Precis, Stonegate, the Selling
Shareholders dated as of February 7, 2002 (the "Stonegate Agreement"), Judith
and, in her absence, Mary are appointed as the contact person for purposes of
determining those Selling Shareholders desiring to sell all or any portion of
their Primary Shares and, if applicable, Secondary Shares at the sale price
proposed by Stonegate or offered by the purchaser.

          4. Precis does not require any additional capital as of the date of
this agreement; however, the Board of Directors of Precis has concluded that it
is in the best interest of Precis and its non-affiliate shareholders to take
actions to increase the number of shares of Common Stock owned by non-affiliates
(ultimately to increase the "public float" of the Common Stock) in order to
establish and maintain a more orderly market of and broaden ownership of the
Common Stock and reduce to some extent the volatility of the Common Stock in the
market place, while avoiding any additional dilution to the current shareholders
of Precis.

          5. Each of the Selling Shareholders will constitute an "underwriter"
within the meaning of the 1933 Act and have the attendant liability.

          6. Each Selling Shareholder desires to be (i) indemnified by Precis
for any and all liabilities and claims arising from or attributable to the offer
and sale of the Shares and (ii) receive contributions from the other Selling
Shareholders for any and all liabilities, claims and expenses arising from or
attributable to the offer and sale of the Shares on a pro rata basis based upon
the sale proceeds that each Selling Shareholder receives pursuant to the sale of
the Shares and the Public Offering.

          NOW, THEREFORE, in consideration of the foregoing and the mutual
covenants and agreements herein contained, and intending to be legally bound
hereby, Selling Shareholders and Precis hereby agree as follows:

          1. SELECTION OF REPRESENTATIVE. Selling Shareholders hereby appoint
and authorize Judith or in her absence, Mary, as their agent and representative
for all purposes under the Stonegate Agreement and for all purposes set forth
herein ("Representative").

          2. PROCEDURES FOR SALE OF SHARES. Pursuant to the Stonegate Agreement,
each offer to purchase Shares ("Purchase Offer") received by Stonegate will be
made to and through Representative.

          2.1 ESTABLISHMENT OF MINIMUM PER SHARE SALE PRICES. Upon execution of
     this Agreement, each Selling Shareholder shall provide to Representative in
     writing the number of Primary Shares and Secondary Shares the Selling
     Shareholder is willing to sell at a specific price per share ("Minimum Sale
     Price"). Each Selling Shareholder shall have the right to change the
     previously established Minimum Sale Price by giving Representative three
     days prior written notice.

          2.2 PURCHASE OFFER GREATER THAN MINIMUM SALE PRICE. In the event
     Stonegate notifies Representative of an offer to purchase Shares ("Purchase
     Offer") and the purchase price per share equals or exceeds the Minimum Sale
     Price, Representative is hereby authorized to sell the Selling
     Shareholder's pro rata portion of the Shares, giving priority to the sale
     of Primary Shares as set forth below, without any further consent or notice
     to the Selling Shareholder. Each Selling Shareholder shall take all
     necessary actions to effectuate any sale in accordance with the provisions
     of this Section 2.2 and the other provisions of this Agreement.

          2.3 PURCHASE OFFER LESS THAN MINIMUM SALE PRICE. In the event the
     Purchase Offer is at a per share price less than the Minimum Sale Price,
     Representative shall use her best efforts to immediately notify, either
     orally or in writing, the Selling Shareholder regarding the terms of the
     offer to purchase Shares, the price per Share, the amount of Primary Shares
     or, if applicable, Secondary Shares that the Selling Shareholder will be
     entitled to sell under the Purchase Offer. Notwithstanding any other
     provision contained in this Agreement, Paul A. Kruger and Randel T. Dunn
     shall first be entitled to sell their Primary Shares and Secondary Shares
     before any other Selling Shareholder. Each Selling Shareholder shall have
     the right and authority to accept or reject such Purchase Offer (in whole
     or in part). In the event a Selling Shareholder elects, either orally or in
     writing, not to sell Selling Shareholder's Primary Shares or, if
     applicable, Secondary Shares, Representative shall be authorized to
     allocate the Shares among Selling Shareholders, including Representative in
     her capacity as a Selling Shareholder, to be sold in connection with such
     Purchase Offer as the Representative determines, in Representative's sole
     and absolute discretion, however, giving first priority to those Selling
     Shareholders that elect to accept such Purchase Offer and that have not
     previously sold all of their Primary Shares until all of their Primary
     Shares have been sold. Although Representative shall use her best efforts
     to notify all of the other Selling Shareholders of any Purchase Offer
     pursuant to this Section 2.3, Representative shall not have any liability
     for failure to notify a Selling Shareholder of such Purchase Offer. The
     failure of a Selling Shareholder to affirmatively accept any offer to
     purchase Shares within 24 hours following Representative's notice of such
     Purchase Offer pursuant to this Section 2.3 shall constitute an election by
     such Selling Shareholder to not accept the Purchase Offer.

          2.4 PRO RATA SALE OF SHARES. Each Selling Shareholder shall have the
     right, but not the obligation, to sell a proportionate number of Primary
     Shares based upon the number of Primary Shares held by the Selling
     Shareholders at the time of the Purchase Offer is received by the
     Representative that have not been previously sold or committed to be sold
     by the Selling Shareholder. Notwithstanding any other provision contained
     in this Agreement, Paul A. Kruger and Randel T. Dunn shall first be
     entitled to sell their Primary Shares and Secondary Shares before any other
     Selling Shareholder. Except as otherwise provided herein, in the event all
     of the Primary Shares have been sold or have been committed to be sold by
     the Selling Shareholder, each Selling Shareholder shall have the right, but
     not the obligation, to sell a proportionate number of Second Shares based
     upon the number of Secondary Shares based upon the number of Secondary
     Shares held by the
                                       -2-
<Page>

     Selling Shareholders at the time of the Purchase Offer is received by the
     Representative that have not been previously sold or committed to be sold
     by the Selling Shareholders.

          2.4 EXPENSES OF PUBLIC OFFERING. Precis hereby agrees to bear all
     costs and expenses of the Public Offering, including without limitation all
     registration and filing fees, printing expenses, fees and disbursement of
     Precis' legal counsel, accounting and auditing fees and disbursement of
     Precis' independent accountants, stock transfer, and sales commissions and
     discounts, if any, associated with the sale of the Shares (including the
     costs and expenses of Stonegate under the Stonegate Agreement and the
     letter agreement dated January 31, 2002) (collectively, the "Offering
     Costs"). To the extent that any Selling Shareholder pays an item of the
     Offering Costs, the Selling Shareholder that paid such Offering Costs shall
     be entitled to reimbursement of such Offering Costs.

     3.  PRECIS INDEMNIFICATION. Precis shall indemnify and hold harmless each
Selling Shareholder (the "Indemnified Party") against any and all investigations
of, preparation for or defense of any pending or threatened liabilities, claims,
judgment, fines and amounts paid in settlement and expenses (including attorneys
fees) actually and reasonably incurred by the Indemnified Party (collectively
the "Loss, Claim or Expense") in connection with any claim or any threatened,
pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative ("Proceeding"), including any action by or in
the right of Precis, to which the Indemnified Party is, was or at any time
becomes a party, or is threatened to be made a party, by reason of the fact that
the Indemnified Party is, was or at any time participant in the sale and
distribution of the Shares as part of the Public Offering and by reason of any
misstatement or omissions to state a material fact by Precis. Precis further
agrees that the Indemnified Party shall not have any liability to Precis or its
affiliates, officers, directors, agents, employees, persons deemed to be in
control of Precis within the meaning of either Section 15 of the Securities Act
of 1933, as amended, or Section 20 of the Securities Exchange Act of 1934, as
amended, or shareholders for any Losses, Claims or Expenses. Precis agrees that
the provisions of this Section 3shall apply (i) whether or not the Indemnified
Party is a formally named party to or the subject or target of any Proceeding
and (ii) in addition to any liability that Precis may otherwise have and shall
be binding upon and inure to the benefit of any successors, assigns, heirs and
personal representatives of Precis or an Indemnified Party.

          3.1 LIMITATIONS ON INDEMNITY. No indemnity pursuant to this Section 3
     shall be paid to the Indemnified Party (i) for the amount of such Loss,
     Claim or Expense for which the Indemnified Party is indemnified pursuant to
     any insurance purchased and maintained by Precis or (ii) on account of the
     Indemnified Party's conduct that is finally adjudged to have been knowingly
     fraudulent, deliberately dishonest or willful misconduct.

          3.2 CONTINUATION OF INDEMNIFY. The provisions of this Section 3 shall
     continue during the period that the Indemnified Party shall be subject to
     any possible Proceeding by reason of the fact that the Indemnified Party
     is, was or at any time a participant in the sale and distribution of the
     Shares as part of the Public Offering.

          3.3 NOTIFICATION AND DEFENSE OF CLAIM. Within 30 days after receipt by
     the Indemnified Party of notice of the commencement of any Proceeding in
     which the Indemnified Party has a right to indemnification pursuant to this
     Section 3, the Indemnified Party shall notify Precis; however, the omission
     of the Indemnified Party to timely notify Precis shall not relieve Precis
     from any liability that Precis may have to the Indemnified Party under this
     Section 3 or otherwise. With respect to any such action, suit or proceeding
     as to which the Indemnified Party notifies Precis of the commencement
     thereof

          (i) Precis will be entitled to participate therein at its own expense
     and

          (ii) Except as otherwise provided below, to the extent that Precis may
     wish, any other person similarly notified by the Indemnified Party will be
     entitled to assume defense thereof, with counsel satisfactory to the
     Indemnified Party. After notice from Precis of its election to assume the
     defense thereof, Precis will not be liable to the Indemnified Party under
     this Section for any additional legal or other expenses subsequently
     incurred by the Indemnified Party in connection with the defense thereof
     other than as otherwise provided below. The Indemnified Party shall have
     the right to employ its own counsel in such action, suit or

                                       -3-
<Page>

     proceeding; provided, however, that the fees and expenses of such counsel
     incurred after notice from Precis of the assumption of the defense thereof
     shall be at the expense of the Indemnifying Party, unless (a) the
     employment of counsel by the Indemnified Party has been authorized by
     Precis, (b) the Indemnified Party shall have reasonably concluded that
     there may be a conflict of interest between Precis and the Indemnified
     Party in the conduct of the defense of such action, or (C)) Precis shall
     not have employed counsel to assume the defense of such action, in each of
     which cases the fees and expense of counsel shall be at the expense of
     Precis. Precis shall not be entitled to assume the defense of any action,
     suit or proceeding brought by or on behalf of Precis or as to which the
     Indemnified Party shall have made the conclusion provided for in (b) above.
     Notwithstanding the foregoing, in no event shall Precis be obligated to
     reimburse the fees or expenses of more than one counsel for the Indemnified
     Party.

          (iii) Precis shall not be liable to indemnify the Indemnified Party
     under this Section 3 for any amount paid in settlement of any Losses,
     Claims or Expenses and related Proceeding effected without Precis' written
     consent. Precis shall not settle any Losses, Claims or Expenses and related
     Proceedings in any manner that would impose any obligation, penalty or
     limitation on the Indemnified Party without the Indemnified Party's written
     consent. Neither Precis nor the Indemnified Party will unreasonably
     withhold its consent to any proposed settlement.

          3.4 REPAYMENT OF EXPENSES. The Indemnified Party shall reimburse
     Precis for all reasonable expenses paid by Precis in defending any
     Proceeding against the Indemnified Party in the event and only to the
     extent that it shall be ultimately determined that the Indemnified Party is
     not entitled to be indemnified by Precis for such expenses under this
     Agreement.

          3.5 ENFORCEMENT. It is hereby acknowledged that the provisions of this
     Section 3 are contained in this Agreement to induce the Indemnified Party
     to participate in the Public Offering with the other Selling Shareholders
     and that the Indemnified Party's participation is, in part, in reliance
     upon the provisions of this Section 3. In the event the Indemnified Party
     is required to bring any action to enforce the Indemnified Party's right to
     collect moneys due under this Section 3 and is successful in such action,
     Precis shall reimburse the Indemnified Party for all of the Indemnified
     Party's attorneys fees and expenses in bringing and pursuing such action.

          3.6 JUDICIALLY IMPOSED LIMITATIONS. If for any reason the
     indemnification provisions of this Section 3 are judicially determined to
     be unavailable or insufficient to hold any Indemnified Party harmless, then
     Precis agrees to contribute to the Losses, Claims or Expenses for which
     indemnification is held unavailable in such proportion as is appropriate to
     reflect not only the relative benefits received by Precis and such
     Indemnified Party, but also relevant fault of each such person or entity,
     as well as any relevant equitable considerations.

     4.  SELLING SHAREHOLDER CONTRIBUTIONS. In recognition of the "underwriter"
status of each Selling Shareholder under the 1933 Act and the Public Offering is
the type of transaction that sometimes results in litigation, in the event
Precis fails to fully indemnify the Indemnified Parties or is prohibited from
indemnifying the Indemnified Parties with respect to any Loss, Claim or Expense
pursuant to Section 3 of this Agreement, each Selling Shareholder (the
"Contributing Shareholder") hereby agrees to contribute and hold harmless each
of the other Selling Shareholders (the "Benefitting Shareholder") against that
percent of any such Loss, Claim or Expenses determined by dividing the sale
proceeds received by the Contributing Shareholder from sale of Shares pursuant
to the Public Offering by the aggregate sum of all proceeds received by the
Selling Shareholders as s group from sale of Shares pursuant to the Public
Offering. The Contributing Shareholder agrees that the provisions of this
Section 4shall apply (i) whether or not the Benefitting Party is a formally
named party to or the subject or target of any Proceeding and (ii) in addition
to any liability that the Contributing Shareholder may otherwise have and shall
be binding upon and inure to the benefit of any successors, assigns, heirs and
personal representatives of the Contributing Shareholder or the Benefitting
Shareholder.

          4.1 LIMITATIONS ON INDEMNITY. No contribution pursuant to this Section
     4 shall be paid to the Benefitting Shareholder (i) for the amount of such
     Loss, Claim or Expense for which the Indemnified Party is

                                       -4-
<Page>

     indemnified pursuant to any policy of insurance or (ii) on account of the
     Benefitting Shareholder's conduct that is finally adjudged to have been
     knowingly fraudulent, deliberately dishonest or willful misconduct.

          4.2 CONTINUATION OF INDEMNIFY. The provisions of this Section 4 shall
     continue during the period that the Benefitting Shareholder shall be
     subject to any possible Proceeding by reason of the fact that the
     Indemnified Party is, was or at any time a participant in the sale and
     distribution of the Shares as part of the Public Offering.

          4.3 NOTIFICATION AND DEFENSE OF CLAIM. Within 30 days after receipt by
     the Benefitting Shareholder of notice of the commencement of any Proceeding
     in which the Benefitting Shareholder has a possible right to contribution
     pursuant to this Section 4, the Benefitting Shareholder shall notify the
     Contributing Shareholder; however, the omission of the Benefitting
     Shareholder to timely notify the Contributing Shareholder shall not relieve
     the Contributing Shareholder from any liability that the Contributing
     Shareholder may have to the Benefitting Shareholder under this Section 4 or
     otherwise. The Benefitting Shareholder shall have the right to employ its
     own counsel in such action, suit or proceeding; provided, however, in no
     event shall the Contributing Shareholder be obligated to reimburse the fees
     or expenses of more than one counsel for the Benefitting Shareholder. The
     Contributing Shareholder shall not be liable for contribution to the
     Indemnified Party under this Section 4 for any amount paid in settlement of
     any Losses, Claims or Expenses and related Proceeding effected without the
     Contributing Shareholder's written consent. The Contributing Shareholder
     will not unreasonably withhold its consent to any proposed settlement.

          4.4 REPAYMENT OF EXPENSES. The Benefitting Shareholder shall reimburse
     the Contributing Shareholder for all reasonable expenses paid by
     Contributing Shareholder, if any, in defending any Proceeding against the
     Benefitting Shareholder in the event and only to the extent that it shall
     be ultimately determined that the Benefitting Shareholder is not entitled
     to receive contribution for such expenses under this Agreement.

          4.5 ENFORCEMENT. It is hereby acknowledged that the provisions of this
     Section 4 are contained in this Agreement to induce the Benefitting
     Shareholder to participate in the Public Offering with the other Selling
     Shareholders and that the Indemnified Party's participation is, in part, in
     reliance upon the provisions of this Section 4. In the event the
     Indemnified Party is required to bring any action to enforce the
     Benefitting Shareholder's right to collect moneys due under this Section 4
     and is successful in such action, the Contributing Shareholder shall
     reimburse the Benefitting Shareholder for all of the Benefitting
     Shareholder's attorneys fees and expenses in bringing and pursuing such
     action.

     5. NOTICES. All notices and other communications given or made pursuant
hereto shall be in writing and shall be deemed to have been duly given or made

Agreement at addresses appearing below the signature of each such party or sent

     13. FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE. No failure or
