June 18, 2001

Mr. Joseph A. Hensley, President
AVIDYN, Inc.
16980 Dallas Pkwy., Suite 120
Dallas, TX 75248

Dear Joe:

Please allow this letter and the attached Schedules A & B to serve as the entire
agreement between AVIDYN, Inc. (the Company), Randall Kurtz (the Employee) and
Tatum CFO Partners, LLP (Tatum CFO).

This letter creates an employment relationship between the Employee and the
Company. This is for the benefit of the Company and to ensure its absolute
control of the Employee in the exercise of his or her employment.

For the services of the Employee, the Company agrees to pay $4,500 per month as
set forth in Schedule A, which also includes other related employment terms.

Tatum CFO's obligation is to make the Employee available to the Company and to
make our resources available to the Employee. Since we do not have a direct
relationship with the Company and the Company controls and directs the Employee,
Tatum CFO cannot and does not assume the same risks we might assume if we
directly supervised the Employee. Schedule B sets forth provisions dealing with
the limitation of liability of Tatum CFO. This allows Tatum CFO to provide this
unique relationship that offers the value of a traditional employment
relationship and the resources and benefits of our national CFO firm.

The Company may for any reason and with 30 days prior written notice to the
Employee and Tatum CFO, terminate the Employee "at will," and the parties
expressly acknowledge that no provision in this agreement, including Schedules A
and B changes the "at will" nature or in any way creates an expressed or implied
term of duration. Likewise, Tatum CFO or the Employee may terminate this letter
agreement for any reason with 30 days prior written notice to the Company, and
immediately if the Company has not remained current in its obligations under
this letter or if the Company engages in or asks the Employee to engage in
illegal or unethical conduct.

<PAGE>   2

Any disputes between the Company and Tatum CFO (whether or not it includes the
Employee as a party) shall be resolved by binding arbitration in Dallas, Texas
under the rules of the American Arbitration Association and governed by Texas
law.

The terms of this letter agreement are severable and may not be amended except
in a writing signed by the parties. Please sign below and return a signed copy
of this letter to indicate your agreement with its terms and conditions.

We look forward to serving you.

Sincerely yours,

TATUM CFO PARTNERS, LLP                     EMPLOYEE

                                   SCHEDULE A

1.      Term of Employment

        Employee will work one day per week beginning July 9, 2001 ("Effective
        Date").

2.      Costs

        Employee will be paid a Monthly Salary ("Salary") of $3,750 and Tatum
        CFO will be paid a Resource Fee ("Fee") of $750. The daily rate for
        additional days (beyond the stated number of days per week) is $900 as
        Salary and $180 as Fee.

        Salary and Fee for the first month will be prorated based upon the
        number of normal workdays remaining in the month. The Salary and Fee
        shall be subject to adjustment annually or at the time the Company makes
        any adjustments or if the Company does not do so, at the time Tatum CFO
        makes its rate adjustments.

3.      Payments

        The Salary will be processed through payroll and paid at the same time
        as other employees. Tatum CFO will invoice the Fee and it will be due by
        the 15th day of the month for which amounts are invoiced.

4.      Payments

        The Company will pay Tatum CFO one full month of the Fee ($750) as a
        deposit upon execution of this Agreement. The deposit will be applied
        against any open amounts due upon the termination of this agreement. Any
        deposit remaining will be promptly returned.

5.      Employee Benefits

        The Company will promptly reimburse the Employee for all out-of-pocket
        business expenses expended on behalf of the Company with appropriate
        prior approval.

        The Employee elects not to participate in the Company's employee
        retirement plan or any other employee benefit plan, and waives any
        coverage that may otherwise exist. The Company will not include Employee
        as a participant in any such plan, unless required to do so by law for
        plan qualification. However, notwithstanding the foregoing, Employee may
        participate in the Company's 401(k) plan at the Company's option.

6.      Other Terms

        For Employee's protection, the following shall apply:

                                       3
<PAGE>   4

        To the extent the Company has directors' and officers' liability
        insurance ("including entity coverage") and/or errors and omissions
        liability insurance in effect, the Company will provide such insurance
        coverage for the Employee along with written evidence to the Employee
        and Tatum CFO that Employee is covered by such insurance.

        Employee may sign federal or state securities filings and reps and
        warranties on behalf of the Company, but only if Employee and Tatum CFO
        receives written evidence that, in signing such filings, reps and
        warranties, he or she is covered by applicable adequate insurance
        (whether director and officer insurance or a special policy) maintained
        by the Company at no additional cost to Employee or Tatum CFO.

        If the Company requests, Employee will serve as an officer of the
        Company, but only if (i) Employee is duly elected as an officer by the
        Company's Board of Directors and (ii) Employee and Tatum CFO has
        received written evidence that he or she is covered as an officer by the
        director and officer insurance maintained by the Company at no
        additional cost to Employee or Tatum CFO.

                                   SCHEDULE B

The following provisions are aimed exclusively at limiting the liability of
Tatum CFO for the reasons stated in the first page of this letter agreement.
Note that these provisions do not affect any traditional employer remedies
against an employee.

1.      Tatum CFO does not make any representations or warranties concerning
        Employee's services. The Company is solely responsible for directing
        Employee as it would any other employee and for evaluating, managing and
        using Employee's services. Tatum CFO makes no representation or warranty
        as to the accuracy or reliability of reports, projections and/or
        forecasts and will not be held liable for any claims of reliance on such
        reports, projections and/or forecasts. Tatum CFO will not be liable for
        any non-compliance with federal, state or local laws or regulations.

2.      The Company may pursue against Employee any remedies the Company may
        have under this letter agreement or at law for breach by Employee of his
        or her duties to the Company. The Company agrees that, absent Tatum
        CFO's breach of express obligations under this letter agreement, or an
        intentional tort by Tatum CFO or Employee, Tatum shall have no liability
        to the Company or third parties based on Employee's breach of duties
        that Employee owes to the Company or third parties.

3.      With the exception of intentional tort by Tatum CFO or Employee, the
        Company agrees to indemnify Tatum CFO to the full extent permitted by
        law for any losses, costs, damages and expenses, including reasonable
        attorneys' fees, as such are incurred, in connection with (i) any cause
        of action, suit or other proceeding arising in connection with Tatum
        CFO's engagement by the Company under this letter agreement, Employee's
        employment with the Company or the provision of services by Employee,
        and (ii) any legal proceeding in which Tatum CFO may be required or
        agree to participate, but in which Tatum CFO is not a party.

4.      If the Company and Tatum CFO are defendants in any action, suit or other
        proceeding, the defense of Tatum CFO will be represented by counsel
        selected by the Company, unless upon advice of Tatum CFO's counsel,
        Tatum CFO will not be adequately represented by the Company's counsel
        because of a conflict of interest or inability to present a defense that
        would otherwise be available to us if separately represented, in which
        case Tatum CFO may be represented by counsel of its own choosing.

5.      As a condition for recovery of any liability, the Company must give
        Tatum CFO written notice of the alleged basis for liability within 30
        days of discovering the circumstances giving rise to such alleged
        liability.

6.      Tatum CFO shall not be liable in any event for incidental or
        consequential damages of the Company, including without limitation, any
        interruption of business or loss of business, profit, or goodwill.

                       AMENDMENT DATED AS OF JULY 17, 2001

     Pursuant to Section 12 of the 1992 Stock Option and Incentive Plan, amended
and restated as of March 14, 1997, as previously amended as of December 19, 1997
and April 15, 1999 (the "Plan"), the Board of Directors of Thornburg Mortgage,
Inc. (the "Company") hereby revises and amends the terms of the Plan as follows:

     1.   The title of the Plan is hereby amended and restated in its entirety
          to read as follows:

          THORNBURG MORTGAGE INC. 1992 STOCK OPTION AND INCENTIVE PLAN

     2.   Section 2(m) of the Plan is amended and restated in its entirety to
          read as follows:

          (m). "Grant" shall mean the issuance of an Incentive Stock Option,
          Non-Statutory Stock Option, DER, SAR, PSR, Restricted Stock, or any
          combination thereof to an Eligible Person.

     3.   Section 2 of the Plan is amended by adding as Section 2(ee) and (ff)
          thereof, the following:

               (ee) "Restricted Stock" shall mean an award of Shares to an
          Eligible Person subject to restrictions on vesting of ownership based
          upon the completion of the Restricted Period or achievement of
          specified performance objectives.

               (ff) "Restricted Period" shall have the meaning ascribed to such
          term in Section 7 (l) (iii).

     4.   Section 7 of the Plan is amended by adding as Section 7(l) thereof,
          the following:

          (l)  Restricted Stock.

               (i) General. Restricted Stock may be granted either alone or in
addition to other Grants under the Plan. The Committee shall determine the
Eligible Persons to whom, and the time or times at which, Grants of Restricted
Stock shall be made. The terms and conditions of a Restricted Stock Grant shall
be determined by the Committee as specified in the Agreement, including but not
limited to: the number of Shares to be Granted; the price, if any, to be paid by
the recipient of Restricted Stock Grants; the Restricted Period as defined in
Section 7(l)(iii); any performance objectives as may be specified in the
Agreement; the date or dates on which restrictions applicable to such Restricted
Stock Grants shall lapse during such Restricted Period; whether the recipient
Eligible Person shall have the right to vote with respect to the Restricted
Stock; whether the recipient Eligible Person shall receive distributions
applicable to the Restricted Stock; and all other conditions of the Restricted
Stock awards. The Committee may also condition the Grant of Restricted Stock
upon such other criteria as the Committee may determine in its sole discretion.
The provisions of Restricted Stock Grants need not be the same with respect to
each recipient.

               (ii) Rights in Restricted Stock. The prospective recipient of a
Restricted Stock Grant shall not have any rights with respect to such Grant,
unless and until such recipient has executed an Agreement evidencing the award
and delivered a fully executed copy thereof to the Company, within a period of
sixty days (or such other period as the Committee may specify) after the Grant
date. Except as may be provided in the applicable Agreement, no dividend shall
be paid to such recipient Eligible Person and such Restricted Stock shall have
no right to vote until the end of the Restricted Period.

               (iii) Restrictions and Conditions. The Grants of Restricted Stock
granted pursuant to this Section 7(l) shall be subject to the following
restrictions and conditions:

                         (A) Subject to the provisions of the Plan and the
Agreement, during such period as may be set by the Committee commencing on the
Grant date (the "Restricted Period"), the Eligible Person shall not be permitted
to sell, transfer, pledge or assign shares of Restricted Stock granted to the
Eligible Person; provided,

<PAGE>   2

however, that the Committee may determine, in its sole discretion, to provide
for the lapse of such restrictions in installments and may accelerate or waive
such restrictions in whole or in part based on such factors and such
circumstances as the Committee may determine, in its sole discretion, including,
but not limited to, the attainment of certain performance related goals, the
Eligible Person's termination, death or Disability or the occurrence of a
"Change of Control" as defined in Section 10.

                         (B) Subject to the provisions of the Agreement and this
Section 7(l), upon termination of employment of any reason during the Restricted
Period, all shares subject to any restriction as of the date of such termination
shall be forfeited by the Eligible Person, and the Eligible Person shall only
receive the amount, if any, paid by the Eligible Person for Restricted Stock.

                         (C) Any Grant of Restricted Stock may be evidenced in
such manner as the Committee may deem appropriate including, without limitation,
book-entry registration or issuance of a stock certificate. If a stock
certificate is issued to evidence the shares of Restricted Stock, such
certificate shall bear an appropriate legend disclosing the restrictions on
transfer hereunder and under the Agreement during the Restricted Period. The
Committee may require that the certificates evidencing Restricted Stock must be
placed in escrow or trust, along with a stock power endorsed in blank, until all
restrictions are removed or expire.

     The Company has caused this amendment of the Plan to be executed in the
name and on behalf of the Company by an officer of the Company thereunto duly
authorized as of July 17, 2001.
