Proxies in the form enclosed, properly executed by stockholders and returned to

accordance with the judgment of the persons designated as proxies. Any proxy on

the office of director named herein. A proxy may be revoked by giving written
notice of such revocation to the Secretary of the Company at any time before
such proxy is voted at the Meeting.

     The Annual Report to Stockholders with respect to the Company's fiscal year
ended December 31, 2001 (Annual Report) is being mailed to stockholders
contemporaneously with the proxy solicitation materials. The Annual Report does

                            EXECUTIVE COMPENSATION

Compensation

     The Company did not pay any compensation to Walter M. Mischer, the Chief
Executive Officer, in 2001, 2000 or in 1999. No other executive officer of the
Company received aggregate direct remuneration from the Company and its
subsidiaries in excess of $100,000 during the 2001, 2000 and 1999 fiscal years.
The Company has no stock option, retirement or pension plans.

Certain Transactions

Sale of Lajitas

     With debt of more than $4,780,000 that had matured and was currently due,
the Company determined in late 1999 that the sale of Lajitas (a resort property
in the Big Bend region of Texas), its sole remaining operating asset, would
facilitate the Company's ability to settle its existing liabilities most
favorably. The Company's decision to sell Lajitas at that time was also
influenced by its perception that a strong marketplace then favored sellers of
specialty properties. Although there had been sporadic efforts to sell Lajitas
prior to 1999, only a few potential buyers ever seriously examined the property
or conducted any due diligence. After considering the efficacy of the Company's
past efforts and reviewing sales of other specialty properties, the Company
determined that the best alternative would be to sell the property through an
auction process. As a result, the Company retained the National Auction Group,
Inc., to conduct an auction of Lajitas. The auction was conducted on February
24, 2000, and the property was sold for $3,950,000.

                                    Page 7

<PAGE>

     The sale of Lajitas included the sale of the capital stock of Lajitas
Utility Co., Inc. (Lajitas Utility), a company which provides water and related
utility services to the resort town.  The Lajitas Utility facilities were in
need of certain repairs and improvements, which were ordered by regulatory
agencies.  The transfer of the capital stock of Lajitas Utility was also subject
to the approval of the regulatory agency.  Subsequent to the auction, the
estimated costs of these repairs increased and, as a result, the Company and the
buyer entered into a series of discussions in order to resolve this matter and
to obtain the necessary approvals.  As a result of these negotiations, the
Company agreed to a reduction in the purchase price of $400,000.  The sale of
the Lajitas property closed on May 2, 2000.  The Company realized a gain during
2000 on the sale of Lajitas of $755,000 and received net cash proceeds of
approximately $2.4 million, after the payment of a mortgage note related to the
property sold.

     The Lajitas resort property was subject to a mortgage in the amount of
$726,000, including accrued interest, in favor of Walter M. Mischer, Chairman of
the Board and Chief Executive Officer of the Company. At closing of the sale of
Lajitas, the Company used a portion of the proceeds to repay this indebtedness
in order to remove the mortgage lien from the property and convey free and clear
title to the buyer.  As part of the property sold, the buyer purchased a portion
of the employee housing at the resort previously owned by Mr. Mischer.  Mr.
Mischer agreed to provide such employee housing for Lajitas at a time when the
Company was unable to finance its construction on acceptable terms.  Mr. Mischer
agreed to sell this housing to the Company for $237,000 which was the cost
incurred by Mr. Mischer in connection with the construction.

Continued Operations and Going Concern Matters

     The Company has attempted to use the net proceeds from the sale of Lajitas
to settle or restructure existing debt, of which approximately $4,831,000 (plus
accrued interest) has matured and is currently past due, and to realize the
carrying amount of its remaining assets.  On March 26, 2002, the Board of
Directors of the Company determined that the best alternative to settle the
Company's existing debt was to file a voluntary petition for relief under
Chapter 11 of Title 11 of the United States Bankruptcy Code (Chapter 11) with
the United States Bankruptcy Court (Bankruptcy Court).   The Company currently
anticipates that it will file its voluntary petition during 2002 and that any
plan of liquidation submitted to the Bankruptcy Court in connection therewith
will call for the disposition of the Company's remaining assets and the
distribution of all the net proceeds therefrom to the Company's creditors.  It
is not presently determinable what amounts the creditors will agree to accept in
settlement of the obligations due them.  Accordingly, the Company believes that
the equity of the Company has, and will continue to have, no value and that any
Chapter 11 plan confirmed by the Bankruptcy Court will result in the elimination
of the equity interests of all of the Company's stockholders.  The Company
anticipates that it will take approximately nine months to complete its
liquidation process; however, any and all Chapter 11 plans that may be proposed
will be subject to obtaining all necessary approvals, including but not limited
to creditor votes and judicial determinations of confirmability.  There can be
no assurance, therefore, as to how long it may take to complete the Company's
liquidation process.

The 1982 Partnership

In 1982 the Board of Directors instituted a Key Employee Equity Participation
Incentive Plan (Incentive Plan) designed to provide incentive compensation for
certain key employees of Mischer Development, Inc. (MDI), the Company's former
wholly owned subsidiary engaged in developing and managing office buildings.  To
implement the Incentive Plan, the Compensation Committee of the Board of
Directors allocated to the participating employees, in the aggregate, a 4.58%
interest in a limited partnership formed in January 1982 (1982 Partnership).
Their interests in the 1982 Partnership are as follows: Walter M. Mischer, Jr.,
President, Chief Operating Officer, and director  1.67%; C. Ronald Blankenship
  1.67%; George Ruhlen  0.83%; and Robert E. McDonald  0.41%.  The limited
partners made capital contributions to the 1982 Partnership at the time of its
formation.  The 1982 Partnership owns a 20% equity interest in a ten-story
office building in Houston, Texas completed in 1983.  As of the date of this
Proxy Statement, the value, if any, ultimately realizable from a limited
partner's interest in the 1982 Partnership is not ascertainable.

Other Transactions

     During 1992, the Company restructured the debt of one of its partnerships.
In connection with this restructure, the Company issued a $300,000 principal
amount note payable to the other joint venture partner. This note was secured by
the Company's 20% equity interest in the venture and was due September 1995. Due
to the Company's financial condition, it was unable to retire this note at
maturity. During December 1995, the partnership through which the Company held
its 20% interest in the joint venture admitted a new class of limited partner (a
company affiliated with Walter M. Mischer) in exchange for a capital
contribution of $306,000. These funds were used to repay the note and accrued
interest. In exchange for the capital contribution, the new limited partner will
receive (i) the first $306,000 of any future cash flow, (ii) interest on the
$306,000 at 10% compounded annually, and (iii) 66 2/3% of any remaining cash
flow. As a result of this transaction, the Company's effective ownership in this
partnership was reduced to 6.7%.

     The Company has no paid employees, and during 2000 entered into an oral
management agreement with a company affiliated with Walter M. Mischer to provide
accounting and other administrative services and related office facilities and
supplies.  These services are provided for a fee of $1,000 per month and totaled
$12,000 for each of 2001 and 2000.

                                    Page 9
<PAGE>

     During 1996, the Company executed a note payable to Mr. Mischer which note
was secured by receivables, was payable monthly as collections on the related
receivables are received, and bore interest at the rate of 9%, with a final
maturity of July 2001.  During 2000, the Company made principal payments
aggregating $65,000 in connection with this note.  As of December 31, 2000, the
outstanding principal balance was $124,000, and the note was paid in full during
2001.  During 1999, the Company executed an additional promissory note in the
principal amount of $200,000 payable to Mr. Mischer. This note was secured by
the Company's ownership interest in a real estate partnership, bore interest at
8% and was due March 31, 2000.  During 1999, the Company borrowed $162,000 on
this note, the proceeds of which were used to fund the auction expenses in
connection with the proposed sale of Lajitas.  The auction expenses were
refunded to the Company at the closing of the Lajitas sale and accordingly the
note was repaid.

     During 1993, in connection with the restructure of the Company's
debentures, the Company issued $3,440,000 in unsecured promissory notes to
certain directors, stockholders and affiliates, including notes to Mr. Mischer,
Mr. Mischer, Jr., John D. Weil and John W. Storms, Trustee, in the aggregate
principal amount of $2,995,000 to consolidate amounts due for the debentures
held by them and accrued and unpaid interest.  These notes bear interest at 6%
compounded annually and were due October 2, 1996.  No payments have been made on
these notes to date.

            SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the Securities Exchange Act of 1934, as amended, requires
the Company's officers, directors and persons who own more than ten percent of a
registered class of the Company's securities to file reports of ownership and
changes in ownership with the Securities and Exchange Commission (the "SEC").
Based solely upon a review of copies of reports filed with the SEC and written
representations from certain of the Company's directors and executive officers
that no other reports were required, the Company notes that all forms required
to be filed during fiscal 2001 under Section 16(c) were timely filed.

                             STOCKHOLDER PROPOSALS

     Stockholders of record desiring to present an appropriate resolution at the
2003 Annual Meeting of Stockholders must furnish the proposed resolution to the
Company no later than December 31, 2002 for inclusion in the Company's proxy
statement and form of proxy relating to such meeting. Furthermore, a stockholder
proposal may be considered untimely if the Company has not received notice of
the proposal at least 45 days prior to the mailing of the proxy statement. In
order to avoid controversy as to the date on which any such proposal is received
by the Company, it is suggested that stockholders submit their proposals by
Certified Mail-Return Receipt Requested.

               RELATIONSHIP WITH INDEPENDENT PUBLIC ACCOUNTANTS

     In past years, including the year ended December 31, 2001, the Audit
Committee has recommended the appointment of independent auditors for the
current year to the Board of Directors, which in turn has recommended
ratification of such appointment by the Company's shareholders. Arthur Andersen
LLP has served as the Company's independent auditor for a number of years,
including the year ended December 31, 2001, and is familiar with the Company's
business affairs, financial controls and accounting procedures. In light of
recent events surrounding Arthur Andersen LLP, the Audit Committee and
management of the Company are performing additional due diligence with respect
to the selection of the Company's independent auditors for the current fiscal
year. Accordingly, the shareholders are not being asked to ratify the
appointment of independent auditors to audit the Company's financial statements
for the year ending December 31, 2002. While the Company is continuing to work
with Arthur Andersen LLP as its independent auditor for the financial statement
review for the first quarter of 2002, the Audit Committee will continue to
monitor the situation and to gather additional information. The Audit Committee
intends to make a decision with respect to the appointment of the Company's
independent auditors for the year ending December 31, 2002 that it believes to
be in the best interests of the Company and its shareholders. Representatives of
Arthur Andersen LLP will be present at the meeting, will have the opportunity to
make a statement if they desire to do so and will be available to respond to
appropriate questions.

Fees

     Arthur Andersen LLP billed the Company the following fees for the fiscal
year ended December 31, 2001:

Company's 2001 fiscal year for review of the Company's annual financial

     The Company did not engage Arthur Andersen LLP to provide advice to the
Company regarding financial information systems design and implementation during
the fiscal year ended December 31, 2001.

All Other Fees

     The Company did not engage Arthur Andersen LLP to provide any other non
audit or tax related services during the fiscal year ended December 31, 2001.

REPORT OF THE AUDIT COMMITTEE

      In connection with the December 31, 2001 financial statements of the
Company, the Audit Committee: (i) reviewed and discussed the audited financial
statements with management, (ii) discussed with the independent auditor the
matters required by Statement on Accounting Standards No. 61, (iii) received the
written disclosures and letter from the independent auditor required by
Independence Standards Board Standard No. 1 and discussed with the independent
auditor the independent auditor's independence, and (iv) considered the
compatibility of any non-audit services provided by the independent auditor with
the auditor's independence. Based upon these reviews and discussions, the Audit
Committee has recommended to the Board of Directors, and the Board of Directors
has approved, that the Company's audited financial statements be included in the
Securities and Exchange Commission Annual Report on Form 10-KSB for the fiscal
year ended December 31, 2001.

                                 OTHER MATTERS

     The enclosed proxy is being solicited on behalf of the Board of Directors
of the Company. The expense of preparing, printing and mailing the form of proxy
and the material used in the solicitation thereof will be borne by the Company.
In addition to solicitation by mail, certain officers and employees may solicit
the return of proxies by telephone, telegram or personal interview. The Company
has requested brokers, custodians, nominees and other record holders to forward
copies of the proxies and soliciting material to persons for whom they hold

expenses.

     The Board of Directors has no information that any matters other than those
referred to in this Proxy Statement will be brought before the Meeting. If,
however, other matters do come before the Meeting, the proxy confers
discretionary authority on the persons named in the proxy to vote it in
accordance with the recommendations of management.
