         This Prospectus relates to the offer and sale from time to time of up
to an aggregate 5,910,263 common shares (the "Resale Shares") of beneficial
interest, par value $0.10 per share ("Common Shares"), of American Industrial

"Selling Shareholders."  The Trust is registering the Resale Shares pursuant to
the Trust's obligations under certain registration rights agreements between
the Trust and each of the Selling Shareholders, but the registration of the

offered or sold by the Selling Shareholders hereunder.

         The Common Shares are listed on the New York Stock Exchange (the
"NYSE") under the symbol "IND."

 SEE "RISK FACTORS" ON PAGE 6 FOR MATERIAL RISKS RELEVANT TO AN INVESTMENT IN
                              THE COMMON SHARES.

         The Selling Shareholders from time to time may offer and sell any
Resale Shares directly or through agents or broker-dealers on terms to be
determined at the time of sale.  To the extent required, the names of any agent
or broker- dealer and applicable commissions or discounts and any other
required information with respect to any particular offer will be set forth in
an accompanying Trust prospectus supplement.  See "Plan of Distribution."  The
Selling Shareholders reserve the right to accept or reject, in whole or in
part, any proposed purchase of the Resale Shares to be made directly or through
agents.

         The Selling Shareholders and any agents or broker-dealers that
participate with the Selling Shareholders in the distribution of the Resale
Shares may be deemed to be "underwriters" within the meaning of the Securities
Act of 1933, as amended (the "Securities Act"), and any commissions received by
them and any profit on the resale of the Resale Shares may be deemed to be
underwriting commissions or discounts under the Securities Act.  See
"Registration Rights" for a description of certain indemnification arrangements
between the Trust and the Selling Shareholders.

         The Trust will not receive any proceeds from the sale of the Resale
Shares by the Selling Shareholders, but has agreed to bear the expenses of
registration of such shares under federal and state securities laws.  All
capitalized terms not otherwise defined herein shall have the meanings ascribed
to them in the Trust's Third Amended and Restated Declaration of Trust (the
"Declaration of Trust").

THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE

                               PROSPECTUS SUMMARY

         The following summary is qualified in its entirety by, and should be
read in conjunction with, the more detailed information appearing elsewhere in
this Prospectus or incorporated herein. This Prospectus, including incorporated
documents, contains forward-looking statements within the meaning of Section
27A of the Securities Act and Section 21E of the Exchange Act.  The Trust's
actual results could differ materially from those set forth in the
forward-looking statements.  Certain factors, among others, which may cause
such a difference are set forth under the caption "Risk Factors" in this
Prospectus.  The information contained herein reflects the Trust's one-for-five
reverse share split (the "Reverse Share Split"), which was approved by the
shareholders and became effective on October 15, 1997.

                                   THE TRUST

         American Industrial Properties REIT (together with its subsidiaries,
the "Trust") is a Texas real estate investment trust that was organized on
September 26, 1985 by the issuance of Common Shares.  On November 27, 1985, the
Trust completed an initial public offering and commenced operations.  The
Trust's investment objective is to maximize the total return to its
shareholders through the acquisition, leasing, management, and disposition of
real estate properties.  The direct and indirect subsidiaries of the Trust
include two operating partnerships of which the Trust is the sole general
partner and owns substantially all of the economic interests directly or
indirectly.

         As of March 31, 1998, the Trust directly or indirectly owned a
portfolio of 39 real estate properties aggregating 4.36 million net rentable
square feet. Included in these amounts are 10 properties aggregating 1.4
million net rentable square feet which the Trust acquired in a merger with four
real estate limited partnerships effective December 31, 1997 (the "Merger").
The Trust's emphasis is in the light industrial sector, which it characterizes
as office showroom, service center and flex properties, low rise offices, and
small bay distribution properties.  Based on net rentable square feet as of
March  31, 1998, approximately 71% of the Trust's portfolio is represented by
light industrial properties, 23% of the portfolio is represented by office
properties and 6% of the portfolio is represented by retail properties.  The
light industrial properties are leased for office, office-showroom, warehouse,
distribution, research and development, and light assembly purposes.  The
retail properties are leased to retail merchandise establishments, restaurants
and a cinema.

         In June 1997, the authorized Common Shares of the Trust were increased
by vote of the shareholders from 10,000,000 to 500,000,000 Common Shares and
the shareholders authorized 50,000,000 Preferred Shares of Beneficial Interest.

         The Trust has qualified as a real estate investment trust ("REIT") for
federal income tax purposes since 1985 and intends to maintain its REIT
qualification in the future.  In order to preserve its REIT status, the Trust
must meet certain criteria with respect to assets, income and shareholder
ownership.  In addition, the Trust is required to distribute at least 95% of
taxable income (as defined in the Internal Revenue Code of 1986, as amended
(the "Code")) to its shareholders.

         The Trust's executive offices are located at 6210 North Beltline Road,
Suite 170, Irving, Texas 75063.  The Trust's main telephone number is
(972)756-6000.


                                  RISK FACTORS

         An investment in Common Shares involves various risks, and prospective
investors should carefully consider the matters discussed under "Risk Factors"
prior to any investment in the Trust.

                                  THE OFFERING

         This Prospectus relates to the possible offer and sale from time to
time of 5,910,263 Resale Shares by the Selling Shareholders.  The Resale Shares
are Common Shares beneficially owned or controlled by the Selling Shareholders.
See "Selling Shareholders."  The Trust is registering the Resale Shares for
sale by the Selling Shareholders pursuant to its obligations under certain
registration rights agreements between the Trust and each of the Selling
Shareholders. The Trust will not receive any proceeds from the sale of any
Resale Shares.

                                  RISK FACTORS

         An investment in the Common Shares involves various risks.
Prospective investors should carefully consider the following information in
conjunction with the other information contained or incorporated by reference
in this Prospectus before making a decision to purchase any Resale Shares.

HISTORY OF LOSSES

         The Trust has generated losses from operations every year since 1988.
Although the Trust anticipates that it will generate income from operations in
the future based on current growth plans, there can be no assurance as to when,
or if, such a change will occur. Furthermore, a significant part of the losses
from operations during the five years ended December 31, 1997 resulted from
write-downs on real estate reflecting permanent impairments in value. Although
additional writedowns are not currently necessary, there can be no assurance
that such writedowns will not be required in the future.

UNCERTAINTY OF DISTRIBUTIONS

         The Trust has not made distributions for four consecutive quarters
since 1993. A distribution of $0.18 per share was paid on April 14, 1998 to
shareholders of record on April 3, 1998. On April 30, 1998, the Board of Trust
Managers declared a distribution for the second quarter of 1998 of $0.20 per
share, payable on July 14, 1998, to shareholders of record as of July 3, 1998.
Prior to April, the Trust made a quarterly distribution on February 13, 1996 of
$0.20 per share.  Any future distributions to shareholders will be evaluated by
the Trust Managers based on the liquidity of the Trust, performance of the
Trust's property portfolio, cash flow of the Trust and other relevant financial
considerations. It is impossible to predict with certainty whether, and when,
the Trust will continue making quarterly distributions after the July 14, 1998
distribution.

ANTI-TAKEOVER PROVISIONS

         The Trust's Declaration of Trust and Fifth Amended and Restated
Bylaws, as amended (the "Bylaws"), as well as the Texas REIT Act, contain a
number of provisions that might have the effect of entrenching current
management or delaying or discouraging an unsolicited takeover of the Trust.
These provisions include, among others, the following: (a) the power of the
Trust Managers to issue 50,000,000 preferred shares of beneficial interest,
$0.10 par value per share (the "Preferred Shares"), with such rights and
preferences as determined by the Trust Managers; (b) the power of the Trust
Managers to stop transfers and/or redeem Shares (as defined in the Declaration
of Trust) under the following conditions: (i) from any shareholder who owns,
directly or indirectly, 9.8% or more of the outstanding Shares, (ii) from any
five or fewer shareholders who own, directly or indirectly more than 50% of the
outstanding Shares and (iii) from any other shareholder if the Trust Managers
otherwise determine in good faith that ownership of the outstanding Shares has
or may become concentrated to an extent that may prevent the Trust from
qualifying as a REIT under the Code; (c) Trust Managers remain in office unless
removed by the shareholders or if another nominee for Trust Manager receives
the vote of a majority of the outstanding Shares regardless of whether they
receive a vote of the majority of the outstanding Shares at the Trust's annual
meeting; and (d) except in certain circumstances, the affirmative vote of the
holders of not less than 80% of the outstanding Shares, including the
affirmative vote of the holders of not less than 50% of the outstanding Shares
not owned, directly or indirectly, by any Related Person (as defined in the
Declaration of Trust), is required for the approval of certain Business
Combinations (as defined in the Declaration of Trust).  Any Shares transferred
in violation of the restrictions set forth in clause (b) of the preceding
sentence become "Excess Securities" with no voting or distribution rights.  The
Trust has the power to purchase or direct the sale of such Excess Securities,
with the sale proceeds being paid to the former owner.

SIGNIFICANT INCREASE IN PORTFOLIO SIZE

         Upon consummation of the Merger, the Trust increased its portfolio of
net leasable square feet owned or controlled by 51% to 4,138,641.  Several of
the properties that were acquired by the Trust in the Merger are in markets
where the Trust has not historically operated properties. Due primarily to the
number and relative geographic diversity of its properties after the Merger,
the Trust may not have adequate management or other personnel or adequate
systems or other resources to manage its portfolio or its properties to the
same level of efficiency after the Merger, which could adversely affect
operations and result in less cash available for distribution to shareholders.

FUTURE DILUTION TO SHAREHOLDERS

         Shareholders are subject to the risk that their equity interests in
the Trust may be diluted through the issuance of additional equity securities
if such securities are issued for less than their fair market value.  The Trust
has the right to issue, at the discretion of its Trust Managers, additional
Common Shares upon such terms and conditions and at such prices as the Trust
Managers may establish.  Additionally, the Trust may in the future issue
Preferred Shares that might have priority over the Common Shares as to
distributions and liquidation proceeds.

DISTRIBUTIONS SUBORDINATE TO PAYMENTS ON DEBT

         Distributions to shareholders of the Trust will be subordinate to the
prior payment of the Trust's current debts and obligations.  If the Trust makes
distributions in the future and, for any reason, the Trust did not have
sufficient funds to pay its current debts and obligations, distributions to
shareholders would be suspended pending the payment of such debts and
obligations.

EFFECT OF MARKET INTEREST RATES ON PRICE OF COMMON SHARES

         An increase in market interest rates may lead prospective purchasers
of the Common Shares to demand a higher anticipated annual yield from future
dividends.  Such an increase in the required anticipated dividend yield may
adversely affect the market price of outstanding Common Shares.

REAL ESTATE INVESTMENT RISKS

EFFECT OF ECONOMIC AND REAL ESTATE CONDITIONS

         Investments in real estate typically involve a high level of risk. One
of the risks of investing in real estate is the possibility that the Trust's
properties will not generate income sufficient to meet operating expenses or
will generate income and capital appreciation, if any, at rates lower than
those anticipated or available through investment in comparable real estate or
other investments. Income from properties and yields from investments in
properties may be affected by many factors, including the type of property
involved, the form of investment, conditions in financial markets,
over-building, a reduction in rental income as the result of the inability to
maintain occupancy levels, adverse changes in applicable tax laws, changes in
general economic conditions, adverse local conditions (such as changes in real
estate zoning laws that may reduce the desirability of real estate in the area)
and acts of nature, such as earthquakes or floods. Some or all of the foregoing
conditions may affect the Trust's properties.

RENEWAL OF LEASES AND RELETTING OF SPACE

         The Trust is subject to the risks that, upon expiration of leases on
the Trust's properties, the leases may not be renewed, the space may not be
relet or the terms of renewal or reletting (including the costs of required
renovation or concessions to tenants) may be less favorable than current lease
terms. If the Trust were unable to promptly relet or renew the leases for all
or a substantial portion of the space, if the rental rate upon such renewal or
reletting were significantly lower than expected or if its reserves proved
inadequate, then the Trust's cash flow and funds from





                                       7
   9
operations ("FFO") and ability to make expected distributions to its
shareholders may be adversely affected.  (The Trust believes FFO is an
appropriate measure of performance and provides investors with an understanding
of the ability of the Trust to incur and service debt and make capital
expenditures.  FFO should not be considered as an alternative to net income or
other measurements under generally accepted accounting principles as an
indicator of the Trust's operating performance or to cash flows from operating,
investing or financing activities as a measure of liquidity.)  Leases on
approximately 13% of the total net leasable area of the properties owned by the
Trust will expire in 1998. The expiring leases represent approximately 9.9% of
the total property annualized base rent received by the Trust. Management will
attempt to negotiate renewals with certain of the tenants with expiring leases;
however, no assurance can be given that such negotiations will be successful.

MARKET ILLIQUIDITY

         Real estate investments are relatively illiquid. Such illiquidity will
tend to limit the ability of the Trust to vary its portfolio promptly in
response to changes in economic or other conditions. In addition, federal
income tax provisions applicable to REITs could limit the Trust's ability to
sell properties held for fewer than four years, which may affect the Trust's
ability to sell properties at a time which would be in the best interest of its
shareholders.

OPERATING RISKS

         The Trust's properties will be subject to all operating risks common
to real estate developments in general, any or all of which might adversely
affect occupancy or rental rates. In addition, increases in operating costs due
to inflation and other factors may not necessarily be offset by increased
rents. If operating expenses increase, the local rental market for properties
similar to the Trust may limit the extent to which rents may be increased to
meet increased expenses without decreasing occupancy rates. If any of the above
occur, the Trust's ability to make distributions to shareholders could be
adversely affected.

COMPETITION

         The Trust's properties are predominantly located in the South and
Southwest.  All of the Trust's properties are located in areas that include
competing properties.  The number of competitive properties in a particular
area could have a material adverse effect on both the Trust's ability to lease
space at any of its properties or at any newly developed or acquired properties
and the rents charged.  The Trust may be competing with owners, including, but
not limited to, other REITs, insurance companies and pension funds that have
greater resources than the Trust.

CONCENTRATION OF INVESTMENTS

         Manhattan Towers, a 301,000 square foot office building, has rental
revenues in excess of 10% of the total revenues of the Trust. Rental revenues
and tenant reimbursements from Manhattan Towers totaled $999,000 in the first
quarter of 1998, representing 11.4% of the Trust's total revenues for the
period.

NO LIMITATION ON DEBT

         The Trust's organizational documents do not contain any limitation on
the amount or percentage of indebtedness the Trust can incur. The Trust could
become more highly leveraged, resulting in an increase in debt service that
could adversely affect the Trust's ability to make distributions to its
shareholders and would result in an increased risk of default on its
obligations.

         Subject to other existing loan documents, the Trust may borrow funds
in the future and secure such loans with mortgages on its properties.  In the
event such mortgage loans require balloon payments, the ability of the Trust to
make such payments will depend upon its ability to sell or refinance its
properties for amounts sufficient to repay such loans.





                                       8
   10
In addition, the payment of debt service in connection with any borrowings may
adversely affect cash flow and the value of the Common Shares.

         As of March 31, 1998, the Trust had $129,000,000 in debt outstanding
and the debt to total market capitalization of the Trust was approximately 44%.

CHANGES IN POLICIES

         The investment and financing policies of the Trust and its policies
with respect to all other activities, including its growth, debt,
capitalization, distribution and operating policies will be determined by its
Trust Managers.  Although the Trust Managers have no present intention to do
so, these policies may be amended or revised at any time and from time to time
at the discretion of the Trust Managers without a vote of the shareholders of
the Trust.  A change in these policies could adversely affect the Trust's
financial condition or results of operations or the market price of its Common
Shares.

POSSIBLE ENVIRONMENTAL LIABILITIES

         Under various federal, state and local environmental laws, ordinances
and regulations, an owner or operator of real estate may become liable for the
costs of removal or remediation of certain hazardous substances released on or
in its property. Such laws typically impose cleanup responsibility and
liability without regard to whether the owner knew of or was responsible for
the presence of the contaminants. The costs of investigation, remediation or
removal of such substances may be substantial, and the presence of such
substances, or the failure to properly remediate such property, may adversely
affect the owner's ability to sell or rent such property or to borrow using
such property as collateral.  Persons who arrange for the disposal or treatment
of hazardous or toxic substances also may be liable for the costs of removal or
remediation of such substances at the disposal or treatment facility, whether
or not such facility is owned or operated by such person. Finally, the owner of
a site may be subject to common law claims by third parties based on damages
and costs resulting from environmental contamination emanating from a site.

         The Trust has been notified of the possible existence of underground
contamination at Tamarac Square, the retail property in Denver, Colorado. The
source of the possible contamination is apparently related to underground
storage tanks located on an adjacent property. This adjacent property was
placed on Colorado's list of leaking underground storage tanks. A second
potential source of contamination is a nearby tract on which a service station
was formerly operated. The owner of the adjacent property is currently
conducting studies under the direction of the Colorado Department of Health in
an attempt to define the contamination and institute an appropriate plan to
address the situation. At this time, management does not anticipate any
exposure to the Trust relative to either issue.

         The due diligence performed by the Trust with respect to the CST
Office Products Building (formerly the Bowater Communications Paper Building)
in Lakeland, Florida, acquired in the Merger, revealed the presence of
naturally occurring metals in groundwater near a former septic system on the
property, but at concentrations which exceeded regulatory thresholds and
expected naturally occurring concentrations.  During its due diligence, the
Trust also conducted an environmental investigation of the Apollo Computer
Building in Chelmsford, Massachusetts. Near the place where underground storage
tanks were formerly operated at the property, such investigation revealed the
presence of hydrocarbons in soil at levels below regulatory thresholds, and
naturally occurring metals in groundwater at concentrations which exceeded
regulatory thresholds and expected naturally occurring concentrations.  The
result of additional investigation by third-party experts indicated that no
discernable liability existed for either property, nor was there any exposure
to future cleanup costs.

         Certain federal, state and local laws, regulations and ordinances
govern the removal, encapsulation or disturbance of asbestos-containing
materials ("ACMs") when such materials are in poor condition or in the event of
building, remodeling, renovation or demolition. Such laws may impose liability
for release of ACMs and may provide for third parties to seek recovery from
owners or operators of real estate for personal injuries associated with ACMs.





                                       9
   11
In connection with its ownership, management and operation of its properties,
the Trust may be potentially liable for such costs. Except as described above,
the Trust has not been notified by any governmental authority or any other
third party of any noncompliance, liability or other claim in connection with
any of the Trust's properties.

         The Trust's management believes that the Trust's properties are in
compliance in all material respects with all federal, state and local laws,
ordinances and regulations regarding hazardous or toxic substances or petroleum
products.  The Trust has not been notified (except with respect to the Tamarac
Square Property), and is not otherwise aware, of any material noncompliance,
liability or claim relating to hazardous or toxic substances in connection with
any of the Trust's properties.

OWNERSHIP LIMITS

         In order to maintain its qualification as a REIT, not more than 50% in
value of the outstanding shares of the Trust may be owned, directly or
indirectly, by five or fewer individuals (as defined in the Code to include
certain entities) during the last half of a taxable year, and such shares must
be beneficially owned by 100 or more persons during at least 335 days of a
taxable year of 12 months, or during a proportionate part of a shorter taxable
year.  In order to protect the Trust against the risk of losing its status as a
REIT due to a concentration of ownership among its shareholders, the
Declaration of Trust authorizes the Trust Managers to take such action as may
be necessary to preserve the Trust's qualification as a REIT.  Additionally,
the Declaration of Trust provides that, subject to certain exceptions, no
holder may own, or be deemed to own, more than 9.8% of the aggregate value of
any class of Shares or 9.8% of the total number of outstanding Shares of any
class of Shares. The Trust Managers are permitted, however, to waive this
restriction if the Trust Managers receive satisfactory evidence and assurances
that the qualification of the Trust as a REIT would not be jeopardized thereby.
Shares acquired or transferred in breach of this limitation will automatically
be deemed to be Excess Securities held by the Trust in trust and not entitled
to vote or to participate in dividends or other distributions.  Additionally,
Shares acquired or transferred in breach of this limitation may be purchased by
the Trust for the lesser of the price paid and the market price (as determined
in the manner set forth in the Declaration of Trust).

         These ownership limits, as well as the ability of the Trust to issue
other classes of equity securities, may delay, defer or prevent a change in
control of the Trust and also may deter tender offers for the Common Shares,
which offers may be attractive to the shareholders, or limit the opportunity of
shareholders to receive a premium for their Common  Shares that might otherwise
exist if an investor were attempting to effect a change in control of the
Trust.

RISKS OF DEVELOPMENT AND ACQUISITION ACTIVITIES

         The Trust will incur risks associated with any development activities
it undertakes, including the risks that: (i) occupancy rates and rents at a
newly completed project may not be sufficient to make the project profitable;
(ii) financing may not be available on favorable terms for the project; (iii)
construction and lease-up may not be completed on schedule, resulting in
increased debt service expense and construction costs; (iv) construction costs
of a project may exceed original estimates, possibly making the project
uneconomical; (v) zoning, occupancy and other required governmental approvals
or authorizations may not be granted and development costs associated therewith
may not be recovered; and (vi) development opportunities explored by the Trust
may be abandoned. Acquisitions of properties entail risks that investments will
fail to perform in accordance with expectations and that judgments with respect
to the costs of improvements to bring an acquired property up to standards
established for the market position intended for that property will prove
inaccurate, as well as general investment risks associated with any new real
estate investment.

         The Trust anticipates that its new developments and acquisitions will
be financed under lines of credit or other interim forms of secured or
unsecured financing. There is no assurance that permanent financing for such
newly developed or acquired projects will be available or might be available
only on disadvantageous terms. In addition, the fact that the Trust must
distribute 95% of its taxable income in order to maintain its qualification as
a REIT will limit the ability of the Trust to rely upon income from operations
or cash flow from operations to finance new development or acquisitions. As a
result, if permanent debt or equity financing is not available on acceptable
terms to refinance new developments or acquisitions undertaken without
permanent financing, further development activities or acquisitions





                                       10
   12
might be curtailed or cash available for distribution might be adversely
affected. In the case of an unsuccessful development or acquisition, the
Trust's loss could exceed its investment in the project.

UNINSURED AND UNDERINSURED LOSSES COULD RESULT IN LOSS OF VALUE OF PROPERTY

         The Trust carries comprehensive liability, fire, flood, extended
coverage and rental loss insurance with respect to its properties and its
management believes such coverage is of the type and amount customarily
obtained for or by an owner of real property assets similar to the Trust's real
property assets. Similar coverage will be obtained for properties acquired in
the future. However, there are certain types of losses, generally of a
catastrophic nature, such as losses from floods or earthquakes, that may be
uninsurable or not economically insurable. The Trust's management exercises its
discretion in determining amounts, coverage limits and deductibility provisions
of insurance, with a view to maintaining appropriate insurance on the Trust's
investments at a reasonable cost and on suitable terms. This may result in
insurance coverage that in the event of a substantial loss would not be
sufficient to pay the full current market value or current replacement cost of
the Trust's lost investment. Inflation, changes in building codes and
ordinances, environmental considerations and other factors also might make it
infeasible to use insurance proceeds to replace the property after such
property has been damaged or destroyed.

COSTS OF COMPLIANCE WITH FEDERAL LAWS

         The Americans with Disabilities Act of 1990 (the "ADA") requires
public accommodations to meet certain federal requirements related to access
and use by disabled persons. These requirements became effective in 1992.
Compliance with the ADA could require removal of structural barriers to
handicapped access in certain public areas of properties owned by the Trust
where such removal is readily achievable. Failure to comply with the ADA could
result in the imposition of fines or the award of damages to private litigants.
If required changes involve greater expenditures than the Trust currently
anticipates, or if the changes must be made on a more accelerated basis than it
anticipates, the Trust's ability to make distributions to its shareholders
could be adversely affected.

         Additional and future legislation may impose other burdens or
restrictions on owners with respect to access by disabled persons. The ultimate
costs of complying with the ADA and other similar legislation are not currently
ascertainable and, while such costs are not expected to have a material adverse
effect on the Trust, such costs could be substantial. Limitations or
restrictions on the completion of certain renovations may limit application of
the Trust's investment strategy in certain instances or reduce overall returns
on the Trust's investments.

ADVERSE CONSEQUENCES OF FAILURE TO QUALIFY AS A REIT

         The Trust believes that it has operated so as to qualify as a REIT
under the Code since its formation. Although management of the Trust believes
that the Trust is organized and is operating in such a manner, no assurance can
be given that the Trust will be able to continue to operate in a manner so as
to qualify or remain so qualified.  Qualification as a REIT involves the
application of highly technical and complex Code provisions for which there are
only limited judicial or administrative interpretations and the determination
of various factual matters and circumstances not entirely within the Trust's
control. For example, in order to qualify as a REIT, at least 95% of the
Trust's gross income in any year must be derived from qualifying sources and
the Trust must make distributions to shareholders aggregating annually at least
95% of its REIT taxable income (excluding net capital gains). In addition, no
assurance can be given that new legislation, regulations, administrative
interpretations or court decisions will not change the tax laws with respect to
qualification as a REIT or the federal income tax consequences of such
qualification. The Trust is not aware, however, of any currently pending tax
legislation that would adversely affect its ability to continue to qualify as a
REIT.

         For any taxable year that the Trust fails to qualify as a REIT, the
Trust will be subject to federal income tax (including any applicable
alternative minimum tax) on its taxable income at corporate rates. In addition,
unless entitled to relief under certain statutory provisions, the Trust also
will be disqualified from treatment as a REIT for the four taxable years
following the year during which qualification is lost. This treatment would
reduce the net earnings of the





                                       11
   13
Trust available for investment or distribution to shareholders because of the
additional tax liability to the Trust for the year or years involved. In
addition, distributions no longer would be required to be made. To the extent
that distributions to shareholders would have been made in anticipation of the
Trust's qualifying as a REIT, the Trust might be required to borrow funds or to
liquidate certain of its investments to pay the applicable tax.

UNCERTAINTIES RELATED TO LITIGATION

         On August 20, 1997, a purported class action lawsuit (the"Arizona
Lawsuit"), which was filed in the Superior Court of the State of Arizona, was
served upon USAA Real Estate Company, USAA Investors I, Inc. ("RELP GP I"),
USAA Investors II, Inc. ("RELP GP II"), USAA Income Properties III, Inc. ("RELP
GP III"), USAA Income Properties IV, Inc.  ("RELP GP IV" and, together with
RELP GP I, RELP GP II and RELP GP III, the "RELP GPs"), certain other
affiliated entities and the individual members of the boards of directors of
each of the RELP GPs. The Trust was also named as a defendant. The Arizona
Lawsuit has been subsequently transferred to the United States District Court
for the Western District of Texas, San Antonio Division.  On April 13, 1998,
another purported class action lawsuit, which was filed on behalf of the former
limited partners of USAA Income Properties III Limited Partnership in the
United States District Court of the Western District of Texas, San Antonio
Division, was served upon USAA Properties III, Inc., Edward B.  Kelley, USAA
Real Estate Company, United Services Automobile Association and the Trust. Both
lawsuits allege, among other things, breaches of fiduciary duty in connection
with the transactions contemplated by merger agreements entered into by USAA
Real Estate Investments I, a California Limited Partnership; USAA Real Estate
Investments II Limited Partnership; USAA Income Properties III Limited
Partnership; and USAA Income Properties IV Limited Partnership and the Trust,
dated as of June 30, 1997.

           Each lawsuit seeks, among other things, damages, including
attorneys' fees and expenses. The Trust believes that the plaintiffs' claims in
both lawsuits are without merit and intends to defend vigorously against each.
However, no assurance can be given that the plaintiffs in the lawsuits will not
be successful.  If such plaintiffs were to succeed in either lawsuit it could
have a material adverse effect on the Trust.


                                USE OF PROCEEDS

         The Common Shares offered hereby are being registered for the account
of the Selling Shareholders and, accordingly, the Trust will not receive any of
the proceeds from the sale of the Resale Shares.

                              SELLING SHAREHOLDERS

         This Prospectus relates to the possible offer and sale from time to
time of 5,910,263 Resale Shares by the Selling Shareholders.  The Selling
Shareholders consist of the following: (i) Praedium, (ii)  Realco, (iii) USAA
I, (iv) USAA II, (v) USAA III, (vi) USAA IV,  (vii) MSRE, (viii) MSAM (as agent
for certain institutional clients and affiliates for whom MSAM acts as an
investment adviser), (ix) ABKB (as agent for certain clients for whom ABKB acts
as an investment adviser), and (x) LaSalle Advisers (as agent for a particular
client for whom LaSalle Advisers acts as an investment adviser).

         Pursuant to the terms of the Common Share Purchase Agreement
("Purchase Agreement") dated as of January 29, 1998 between the Trust and
Praedium, Praedium obtained full observation rights with respect to the Trust's
Board of Trust Managers ("Observation Rights"), including the right to obtain
full and timely notice of all meetings of the Board of Trust Managers and of
each of its committees, to obtain copies of all written and other materials
disseminated to the Board of Trust Managers and to designate a person to attend
in person or by telephone all meetings of the Board of Trust Managers or its
committees. Praedium's Observation Rights shall terminate upon the earlier of
(i) the occurrence of the Trust's annual meeting in 1999, or (ii) such time
that Praedium owns less than 50% of the Common Shares acquired pursuant to the
terms of the Purchase Agreement. In connection with its Observation Rights and
contemporaneously with the execution of the Purchase Agreement, Praedium
executed a confidentiality agreement.

         Edward B. Kelley and T. Patrick Duncan, President and Senior Vice
President of Real Estate Operations of Realco, respectively, currently serve as
Trust Managers of the Trust.  Pursuant to the terms of the Share Purchase
Agreement dated as of December 13, 1996 between the Trust and Realco, as
amended, Realco retains the right to nominate an additional two Trust Managers
to the Trust's Board of Trust Managers, subject to approval by shareholders.
Messrs.  Kelley and Duncan also serve as directors and officers of each of USAA
I, USAA II, USAA III and USAA IV, each of which is a wholly-owned subsidiary of
Realco.  An affiliate of Realco currently manages and leases the properties
acquired by the Trust in the Merger.

         Pursuant to the terms of an agreement by and among the Trust, USAA,
ABKB, LaSalle Advisers, MSAM and MSRE dated January 29, 1998, the Trust shall
nominate for election or re-election as Trust Manager at each annual meeting of
shareholders one nominee of MSAM and one nominee of ABKB, in each case as agent
and for the benefit of particular clients. The Trust shall have no further
obligation to nominate MSAM's and ABKB's nominee, as applicable, at the time
MSAM's or ABKB's holdings, as applicable, of the Trust's Common Shares fall
below 5% of the Trust's issued and outstanding shares. Upon determining that a
party has fallen below the threshold, the Trust may require such party's
nominee to immediately resign or to not seek election at the next annual
meeting of shareholders.

         The Resale Shares offered by this Prospectus will be offered from time
to time by the Selling Shareholders, or by pledgees, donees, transferees or
other successors in interest thereto.  The following table provides the number
of Common Shares beneficially owned and offered by each Selling Shareholder.

                              PLAN OF DISTRIBUTION

         This Prospectus relates to the offer and sale from time to time of up
to an aggregate of 5,910,263 Resale Shares by the Selling Shareholders, or by
pledgees, donees, transferees or other successors in interest thereto. The
Trust is registering the Resale Shares pursuant to the Trust's obligations
under the Registration Rights Agreements, but the registration of the Resale
Shares does not necessarily mean that any of the Resale Shares will be offered
or sold by the Selling Shareholders thereunder.  The Trust will not receive any
proceeds from the sale of the Resale Shares by the Selling Shareholders.

         The distribution of the Resale Shares may be effected from time to
time in one or more underwritten transactions at a fixed price or prices, which
may be changed, or at market prices prevailing at the time of sale, at prices
related to such prevailing market prices or at negotiated prices.  Any such
underwritten offering may be on a "best efforts" or a "firm commitment" basis.
In connection with any such underwritten offering, underwriters or agents may
receive compensation in the form of discounts, concessions or commissions from
the Selling Shareholders.  Underwriters may sell the Resale Shares to or
through dealers, and such dealers may receive compensation in the form of
discounts, concessions or commissions from the underwriters and/or commissions
from the purchasers for whom they act as agents.

         The Selling Shareholders and any underwriters, dealers or agents that
participate in the distribution of the Resale Shares may be deemed to be
"underwriters" within the meaning of the Securities Act, and any profit on the
sale of the Resale Shares by them and any discounts, commissions or concessions
received by any such underwriters, dealers or agents might be deemed to be
underwriting discounts and commissions under the Securities Act.

         At a time a particular offer of Resale Shares is made by the Selling
Shareholders, a Prospectus Supplement, if required, will be distributed that
will set forth the names of any underwriters, dealers or agents and any
discounts, commissions and other terms constituting compensation from the
Selling Shareholders and any other required information.





                                       14
   16
         The sale of Resale Shares by the Selling Shareholders also may be
effected from time to time by selling Resale Shares directly to purchasers or
to or through broker-dealers.  In connection with any such sale, any such
broker-dealer may act as agent for the Selling Shareholders or may purchase
from the Selling Shareholders all or a portion of the Resale Shares as
principal, and may be made pursuant to any of the methods described below.
Such sales may be made on the NYSE or other exchanges on which the Common
Shares are then traded, in the over-the-counter market, in negotiated
transactions or otherwise at prices and at terms then prevailing or at prices
related to the then-current market prices or at prices otherwise negotiated.

         The Resale Shares also may be sold in one or more of the following
transactions: (a) block transactions in which a broker-dealer may sell all or a
portion of such shares as agent but may position and resell all or a portion of
the block as principal to facilitate the transaction; (b) purchases by any such
broker-dealer as principal and resale by such broker-dealer for its own account
pursuant to a Prospectus Supplement; (c) a special offering, an exchange
distribution or a secondary distribution in accordance with applicable NYSE or
other stock exchange rules; (d) ordinary brokerage transactions and
transactions in which any such broker-dealer solicits purchasers; (e) sales "at
the market" to or through a market maker or into an existing trading market, on
an exchange or otherwise, for such shares; and (f) sales in other ways not
involving market makers or established trading markets, including direct sales
to purchasers.  In effecting sales, broker-dealers engaged by the Selling
Shareholders may arrange for other broker-dealers to participate.
Broker-dealers will receive commissions or other compensation from the Selling
Shareholders in amounts to be negotiated immediately prior to the sale that
will not exceed those customary in the types of transactions involved.
Broker-dealers may also receive compensation from purchasers of the Resale
Shares which is not expected to exceed that customary in the types of
transactions involved.

         In order to comply with the securities laws of certain states, if
applicable, the Resale Shares may be sold only through registered or licensed
brokers or dealers.  In addition, in certain states, Resale Shares may not be
sold unless they have been registered or qualified for sale in such state or an
exemption from such registration or qualification requirement is available and
is satisfied.

         All expenses incident to the offering and sale of the Resale Shares,
other than commissions, discounts and fees of underwriters, broker-dealers or
agents, shall be paid by the Trust.  The Trust has agreed to indemnify the
Selling Shareholders against certain losses, claims, damages and liabilities,
including liabilities under the Securities Act.

                        FEDERAL INCOME TAX CONSEQUENCES

         The Trust has elected to be taxed as a REIT for federal income tax
purposes since its taxable year ended December 31, 1985.  The following general
summary of the Federal tax rules governing a REIT and its shareholders is based
on the Code, judicial decisions, Treasury Regulations, rulings and other
administrative interpretations, all of which are subject to change. Because
many provisions of the Code have been revised substantially by recent
legislation, very few judicial decisions, Treasury Regulations, rulings or
other administrative pronouncements have been issued interpreting many of the
revisions to the Code. Liddell, Sapp, Zivley, Hill & LaBoon, L.L.P. has acted
as counsel to the Trust and has reviewed this summary and has rendered an
opinion that the description of the law and the legal conclusions contained
herein are correct in all material respects, and that the discussion hereunder
fairly summarizes the federal income tax considerations that are likely to be
material to the Trust and a holder of Common Shares.  However, investors should
be aware that Congress continues to consider new tax bills. Accordingly, no
assurance can be given that future legislation, administrative regulations,
rulings, or interpretations or court decisions will not alter significantly the
tax consequences described below or that such changes or decisions will not be
retroactive. The Trust has not requested, nor does it presently intend to
request, a ruling from the Internal Revenue Service (the "Service") with
respect to any of the matters discussed below. Because the provisions governing
REITs are complex, no attempt is made in the following discussion to discuss in
detail all of the possible tax consequences applicable to the Trust or its
shareholders, including state tax laws. ACCORDINGLY, THIS DISCUSSION IS NOT
INTENDED AS A SUBSTITUTE FOR CAREFUL TAX PLANNING AND EACH PROSPECTIVE INVESTOR
IS URGED TO CONSULT HIS OR HER OWN TAX ADVISER WITH SPECIFIC REFERENCE TO HIS
OR HER OWN TAX SITUATION BEFORE PURCHASING COMMON SHARES.





                                       15
   17
GENERAL

         In general, as long as the Trust qualifies as a REIT, it will not be
subject to Federal income tax on income or capital gains that it distributes in
a timely manner to shareholders. The Trust will, however, be subject to tax at
normal corporate rates upon any taxable income or capital gain not distributed.

         If the Service successfully challenged the tax status of the Trust as
a REIT, the Trust's income and capital gains would become subject to Federal
income tax (including any applicable minimum tax) at corporate rates.
Consequently, the amount of after tax earnings available for distribution to
shareholders would decrease substantially.  In addition, "net capital gain"
(net long-term capital gain in excess of net short-term capital loss)
distributed by the Trust would be taxed as ordinary dividends to shareholders
rather than as long-term capital gain. The Trust would not be eligible to
re-elect REIT status under the Code until the fifth taxable year beginning
after the taxable year in which it failed so to qualify, unless its failure to
qualify was due to reasonable cause and not to willful neglect and certain
other requirements were satisfied. Also, immediately prior to requalification
as a REIT under the Code, the Trust could be taxed on any unrealized
appreciation in its assets.

         Qualification of the Trust as a REIT for Federal tax purposes will
depend on its continuing to meet various requirements governing, among other
things, the ownership of its Common Shares, the nature of its assets, the
sources of its income, and the amount of its distributions to shareholders.
Although the Trust Managers intend to cause the Trust to continue to operate in
a manner that will enable it to comply with such requirements, there can be no
certainty that such intention will be realized. In addition, because the
relevant laws may change, compliance with one or more of the REIT requirements
may be impossible or impractical.

REQUIREMENTS FOR QUALIFICATION AS A REAL ESTATE INVESTMENT TRUST

         Although the Trust must meet certain qualifications to be a real
estate investment trust under the Texas REIT Act, the Trust must independently
qualify as a REIT under the Code. To qualify as a REIT under the Code, the
Trust must properly elect to be a real estate investment trust and must satisfy
various requirements in each taxable year.  Generally, for federal income tax
purposes an entity will not qualify as a REIT unless it is a corporation, trust
or association (i) which is managed by one or more trustees or directors; (ii)
the beneficial ownership of which is evidenced by transferable shares, or by
transferable certificates of beneficial interest; (iii) which would be taxable
as a domestic corporation, but for Sections 856 through 859 of the Code; (iv)
which is neither a financial institution nor an insurance Trust subject to
certain provisions of the Code; (v) the beneficial ownership of which is held
by 100 or more persons; (vi) during the last half of each taxable year not more
than 50% in value of the outstanding stock of which is owned, directly or
constructively, by five or fewer individuals (as defined in the Code to include
certain entities); and (vii) which meets certain other tests, described below,
regarding the nature of its income and assets.  The Code provides that
conditions (i) to (iv), inclusive, must be met during the entire taxable year
and that condition (v) must be met during at least 335 days of a taxable year
of 12 months, or during a proportionate part of a taxable year of less than 12
months. Conditions (v) and (vi) will not apply until after the first taxable
year for which an election is made to be taxed as a REIT.

         The Trust believes that it has issued sufficient shares to allow it to
satisfy conditions (v) and (vi). In addition, the Declaration of Trust provides
for restrictions regarding the transfer and ownership of shares, which
restrictions are intended to assist the Trust in continuing to satisfy the
share ownership requirements described in (v) and (vi) above. Those
restrictions may not ensure that the Trust in all cases will be able to satisfy
the share ownership requirements described above. If the Trust fails to satisfy
those share ownership requirements, the Trust's status as a REIT will
terminate. Pursuant to the Taxpayer Relief Act of 1997, enacted August 5, 1997,
starting with a REIT's first taxable year that begins after August 5, 1997, a
REIT that complies with Treasury Regulations for ascertaining the ownership of
its shares and that does not know or, exercising reasonable diligence would not
have known, whether it failed condition





                                       16
   18
(vi) will be treated as meeting condition (vi). The provisions of the Taxpayer
Relief Act of 1997 will apply to each of the Trust's taxable years which begin
after August 5, 1997.

         Share Ownership. (a) The beneficial ownership of Common Shares of the
Trust must be held by a minimum of 100 persons for at least 335 days of a
taxable year consisting of 12 months (or a proportionate part of a taxable year
consisting of less than 12 full months), and (b) Common Shares representing no
more than 50% (by value) of the Trust may be owned (directly or under rules of
constructive ownership prescribed by the Code) by five or fewer individuals at
any time during the last half of a taxable year (the "50% Shareholder Test").
Certain tax-exempt entities are treated as individuals for purposes of the 50%
Shareholder Test. In addition, the applicable constructive ownership rules
provide, among other things, that Common Shares held by a corporation,
partnership, trust or estate will be regarded as being held proportionately by
its shareholders, partners or beneficiaries, as the case may be, and Common
Shares owned by certain persons may be regarded as being owned by certain
members of their families. Common Shares held by a qualified pension plan will
be treated as held proportionately by its beneficiaries; however, Common Shares
held by a qualified pension plan will be treated as held by one individual if
persons related to the plan (such as the employer, employees, officers, or
Trust Managers) own in the aggregate more than 5% by value of the Common Shares
and the Trust has accumulated earnings and profits attributable to any period
for which it did not qualify as a REIT.

         To assure continued compliance with the 50% Shareholder Test, the
Trust's Declaration of Trust prohibits any individual investor from acquiring
an interest in the Trust such that the individual would own (or be deemed under
the applicable rules of constructive ownership to own) more than 9.8% of the
outstanding Common Shares, unless the Trust Managers (including a majority of
the independent Trust Managers) are provided evidence satisfactory to them in
their sole discretion that the qualification of the Trust as a REIT will not be
jeopardized.

         Treasury Regulations require the Trust to maintain records of the
actual and constructive beneficial ownership of its Common Shares. Pursuant to
the Taxpayer Relief Act of 1997, if the Trust fails to comply with regulations
to ascertain its ownership it will be subject to a penalty for failing to do
so. The penalty is $25,000 ($50,000 for intentional violations) for any year in
which the Trust does not comply with the ownership regulations. The Trust will
also be required, when requested by the Service, to send curative demand
letters. In accordance with those Regulations, the Trust must and will demand
from shareholders written statements concerning the actual and constructive
beneficial ownership of Common Shares. Any shareholder who does not provide the
Trust with required information concerning share ownership will be required to
include certain information relating thereto with his income tax return.

         Asset Diversification. At the close of each quarter of the taxable
year, at least 75% of the value of the Trust's total assets must be represented
by "real estate assets" (which category includes interests in real property,
mortgages on real property and certain temporary investments), cash, cash items
and U.S. Government securities (the "75% Asset Test"). In addition, no more
than 25% of the value of the Trust's total assets may consist, in whole or in
part, of securities that do not qualify under the 75% Asset Test (the "25%
Asset Test"). Further, the value of any one issuer's securities owned by the
Trust may not exceed 5% of the value of the Trust's total assets (the "5% Asset
Test"), and the Trust may not own more than 10% of any one issuer's voting
securities (the "10% Test"). If the Trust is in violation of the foregoing
requirements (due to a discrepancy between the value of its investments and
such requirements) after the acquisition of any security or property, then the
Trust will be treated as not violating the requirements if it cures the
violation within 30 days of the close of the quarter during which the Trust
acquires such asset.

         While the Trust Managers intend to manage the Trust to meet the 75%
Asset Test, 25% Asset Test, 5% Asset Test and 10% Test, no assurance can be
given that the Trust will be able to do so.

         The assets of the Trust's wholly-owned subsidiaries will be
attributable directly to the Trust for purposes of the asset diversification
rules. Additionally, the Trust will be deemed to own a proportionate share
(based upon its capital interest) of the assets of any partnerships in which
the Trust owns an interest.





                                       17
   19
         Sources of Income. The Trust must satisfy three distinct income-based
tests for each taxable year: the "75% Income Test," the "95% Income Test" and
the "30% Income Test."

         The 75% Income Test requires that at least 75% of the Trust's gross
income (other than from certain "prohibited transactions") in each taxable year
consist of certain types of income identified in the Code, including qualifying
rents from real property; qualifying interest on obligations secured by
mortgages on real property or interests in real property; gain from the sale or
other disposition of real property (including interests in real property and
mortgages on real property) held for investment and not primarily for sale to
customers in the ordinary course of business; income and gain from certain
properties acquired by the Trust through foreclosure; and income earned from
certain qualifying types of temporary investments. Income earned from
qualifying temporary investments means income that is (i) attributable to stock
or debt instruments, (ii) attributable to the temporary investment of capital
received by the Trust from the issuance of shares of beneficial interest or
from a public offering of debt securities that have a maturity of at least five
years, and (iii) received or accrued within one year from the date the Trust
receives such capital. Interest income and gain realized from the disposition
of loans which are secured solely by real property will constitute qualifying
income for purposes of the 75% Income Test, assuming that such interest income
is not excluded from the calculation of interest for purposes of the 75% Income
Test by reason of such interest being dependent on income or profits as
described in Code Section 856(f) and assuming that any such loan which is
disposed of is held for investment and not primarily for sale to customers in
the ordinary course of a trade or business.

         Under the 95% Income Test, at least 95% of the Trust's gross income
(other than from certain "prohibited transactions") in each taxable year must
consist of income which qualifies under the 75% Income Test as well as
dividends and interest from any other source, gain from the sale or other
disposition of Shares and other securities which is not dealer property, any
payment to the Trust under an interest rate swap or cap agreement entered into
as a hedge against variable rate indebtedness incurred to acquire or carry real
estate assets, and any gain from the disposition of such an agreement.

         Finally, under the 30% Income Test, the Trust must limit its
realization of certain types of income so that, in each taxable year, less than
30% of its gross income is derived from sale or other disposition of (a) Shares
or securities held for less than one year (which includes an interest rate swap
or cap agreement entered into by the Trust as a hedge against any variable rate
indebtedness incurred to acquire or carry real estate assets), (b) with certain
limited exceptions, real property (including interests in and mortgages on real
property) held for less than four years and (c) property in a transaction
treated as a "prohibited transaction" under the Code. Pursuant to the Taxpayer
Relief Act of 1997, the 30% Income Test is eliminated, starting with a REIT's
first taxable year that begins after August 5, 1997.

         The income of the Trust's wholly-owned subsidiaries will be
attributable to the Trust for purposes of the income tests described above.
Additionally, a proportionate share of the items of income of any partnership
in which the Trust owns an interest will be attributable to the Trust (based on
the Trust's capital interest in any such partnership).

         If the Trust fails to meet the requirements of either or both the 75%
Income Test or the 95% Income Test in a taxable year but otherwise meets the
applicable requirements for qualification as a REIT, it may nevertheless
continue to qualify under the Code as a REIT if certain conditions are met.
While satisfaction of the conditions would prevent the Trust from losing its
tax status as a REIT, the Trust generally would be liable for a special tax
equal to 100% of the greater amount by which the Trust fails the 75% Income
Test or the 95% Income Test. The Code does not provide for any mitigation
provisions with respect to the 30% Income Test. Accordingly, if the Trust
failed to meet the 30% Income Test, if applicable, its tax status as a REIT
would terminate.

         Rents received by the Trust will qualify as "rents from real property"
in satisfying the gross income requirements for a REIT described above only if
several conditions are met. First, the amount of rent must not be based in
whole or in part on the income or profits of any person. However, an amount
received or accrued generally will not be excluded from the term "rents from
real property" solely by reason of being based on a fixed percentage or
percentages of receipts or sales. Second, the Code provides that rents received
from a tenant will not qualify as "rents





                                       18
   20
from real property" in satisfying the gross income tests if the REIT, or an
owner of 10% or more of the REIT, directly or constructively owns 10% or more
of such tenant (a "Related Party Tenant"). Third, if rent attributable to
personal property, leased in connection with a lease of real property, is
greater than 15% of the total rent received under the lease, then the portion
of rent attributable to such personal property will not qualify as "rents from
real property." Finally, for rents received to qualify as "rents from real
property," the REIT generally must not operate or manage the property or
furnish or render services to the tenants of such property, other than through
an independent contractor from whom the REIT derives no revenue, provided,
however, the Trust may directly perform certain services that are "usually or
customarily rendered" in connection with the rental of space for occupancy only
and are not otherwise considered "rendered to the occupant" of the property.
Moreover, pursuant to the Taxpayer Relief Act of 1997, income derived by a REIT
from non-qualifying services provided to tenants or from managing or operating
a property which it owns will not be treated as rent from real property unless
such income does not exceed one percent of the REIT's gross income from the
property. The Trust does not and will not (i) charge rent for any property that
is based in whole or in part on the income or profits of any person (except by
reason of being based on a percentage of receipts or sales, as described
above), (ii) rent any property to a Related Party Tenant, (iii) derive rental
income attributable to personal property (other than personal property leased
in connection with the lease of real property, the amount of which is less than
15% of the total rent received under the lease), or (iv) perform services
considered to be rendered to the occupant of the property (unless the income
from those services qualifies as rent from real property pursuant to the
Taxpayer Relief Act of 1997) other than through an independent contractor from
whom the Trust derives no revenue. The Trust believes that the aggregate amount
of any non-qualifying income in any taxable year will not exceed the limit on
non- qualifying income under the gross income tests.

         Distribution Requirements. With respect to each taxable year, the
Trust must distribute to shareholders an amount at least equal to the sum of
95% of its "REIT taxable income," computed without regard to the dividends paid
deduction and by excluding any net capital gain ("net investment income"), and
95% of the excess of its net income from "foreclosure property" over the
Federal income tax imposed on such income, minus certain items of noncash
income. The Trust distributes substantially all of its net investment income
annually. The Trust likewise distributes annually substantially all of its
realized net capital gains. The Service may waive the distribution requirements
for any tax year if the Trust establishes that it was unable to meet such
requirements by reason of distributions previously made to meet the requirement
of section 4981 of the Code (relating to the 4% Federal excise tax on
undistributed income discussed below).

         Unlike net investment income, the Trust's net capital gain need not be
distributed in order for the Trust to maintain its status under the Code as a
REIT; however, the Trust will be taxable on any net capital gain and net
investment income which it fails to distribute in a timely manner. Pursuant to
the Taxpayer Relief Act of 1997, a REIT may elect to retain and pay income tax
on net long-term capital gains that it receives during a taxable year. If a
REIT makes this election, its shareholders are required to include in their
income as long-term capital gain their proportionate share of the undistributed
long-term capital gains so designated by the REIT. A shareholder will be
treated as having paid his or her share of the tax paid by the REIT in respect
of long-term capital gains so designated by the REIT, for which the shareholder
will be entitled to a credit or refund. In addition, the shareholder's basis in
his or her REIT shares will be increased by the amount of the REIT's designated
undistributed long-term capital gains that are included in the shareholder's
long-term capital gains, reduced by the shareholder's proportionate share of
tax paid by the REIT on those gains that the shareholder is treated as having
paid. The earnings and profits of the REIT will be reduced, and the earnings
and profits of any corporate shareholder of the REIT will be increased, to take
into account amounts designated by the REIT pursuant to this rule. A REIT must
pay its tax on its designated long-term capital gains within 30 days of the
close of any taxable year in which it designates long-term capital gains
pursuant to this rule, and it must mail a written notice of its designation to
its shareholders within 60 days of the close of the taxable year.

         Distributions in excess of current and accumulated earnings and
profits will not be taxable to a shareholder to the extent that they do not
exceed the adjusted basis of the shareholder's shares, but rather will reduce
the adjusted basis of such shares. To the extent that such distributions exceed
the adjusted basis of a shareholder's shares they will be included in income as
long-term capital gain (or short-term capital gain if the shares have been held
for one year or less)





                                       19
   21
assuming the shares are a capital asset in the hands of the shareholder. In
general, gain will be treated as long-term capital gain if the Common Shares
have been held for more than one year and as short-term capital gain if the
Common Shares have been held for one year or less.  The Taxpayer Relief Act of
1997 has changed the tax rates and holding periods applicable to long-term
capital gains of individuals.  In general, under applicable provisions of the
Taxpayer Relief Act of 1997, which are generally effective for taxable years
ending after May 1, 1997, the maximum tax rate applicable to net capital gains
of individuals realized upon the sale of property held for 18 months or more is
20% (10% for individuals in a tax bracket below 28%), and the maximum tax rate
on net capital gains of individuals realized upon the sale of property for more
than one year and for not more than 18 months is 28%.  The Taxpayer Relief Act
of 1997 does not affect the taxation of a corporation's capital gains.

         While the Trust expects to meet its distribution requirements, its
ability to make distributions may be impaired if it has insufficient cash flow
or otherwise has excessive noncash income or nondeductible expenditures.
Furthermore, the distribution requirement may be determined not to have been
met in a given year by reason of the Service later successfully challenging the
deductibility of a Trust expenditure. In such event, however, it may be
possible to cure a failure to meet the distribution requirement with a
"deficiency dividend," but if the Trust uses that procedure, it may incur
substantial tax penalties and interest.

         The Trust will be subject to a nondeductible 4% Federal excise tax
with respect to undistributed ordinary income and capital gain net income
unless it also meets a calendar year distribution requirement. To meet this
requirement, the Trust must, in general, distribute with respect to each
calendar year an amount equal to the sum of (a) 85% of its ordinary income
(adjusted under the Code for various items), (b) 95% of its capital gains in
excess of its capital losses (subject to certain adjustments) and (c) any
ordinary income and capital gain net income not distributed in prior calendar
years. The Trust intends to make distributions to shareholders so that it will
not incur this tax but, as noted above, various situations could make it
impractical to meet the prescribed distribution schedule.

         The Trust is authorized to issue Preferred Shares. Should the Trust do
so, and should the Trust distribute a capital gain dividend while Preferred
Shares are outstanding, it may be required to designate a portion of dividends
entitled to be received by holders of the Preferred Shares as capital gain
dividends, thereby reducing the portion of total distributions paid to holders
of the Trust's Common Shares which may be characterized as capital gains
dividends.

FEDERAL TAXATION OF THE TRUST -- SPECIFIC ITEMS

         Dispositions of Assets. The Trust may realize a gain or loss on the
disposition of an asset that it owns. The gain or loss may be capital or
ordinary in character, depending upon a number of factors and the tax rules
governing the type of disposition involved.

         If the Trust were deemed to be holding property (such as real property
or loans) primarily for sale to customers in the ordinary course of business
(i.e., as a "dealer"), then (a) any gains recognized by the Trust upon the
disposition of such property would be subject to a 100% tax on prohibited
transactions and (b) depending on the composition of the Trust's total gross
income, the Trust could fail the 30% Income Test or the 75% Income Test for
qualification as a real estate investment trust.

         Under existing law, whether property is held primarily for sale to
customers in the ordinary course of business must be determined from all the
facts and circumstances surrounding the particular property and sale in
question. The Trust intends to hold all property for investment purposes and to
make occasional dispositions which are, in the opinion of the Trust Managers
and the Investment Manager, consistent with the Trust's investment objectives
and in compliance with all the rules discussed above governing the
qualification of the Trust for REIT status under the Code. Accordingly, the
Trust does not expect to be treated as a "dealer" with respect to any of its
assets. No assurance, however, can be given that the Service will not take a
contrary position.





                                       20
   22
         Alternative Minimum Tax. Under certain circumstances, the Trust may be
subject to the alternative minimum tax on its items of tax preference.

         Net Income From Foreclosure Property. If the Trust has net income from
foreclosure property that is not otherwise qualifying income for REIT purposes,
it will be subject to tax on such income at the highest corporate rate.
Foreclosure property generally means real property (and any personal property
incident to such real property) which is acquired as a result of a default
either on a lease of such property or on indebtedness which such property
secured and with respect to which an appropriate election is made.

PROPOSED LEGISLATION

         President Clinton's budget proposal for 1999 includes several
provisions that would affect the tax treatment of REITs. Included among these
provisions is a call for a freeze on the grandfathered status of "stapled" or
paired REITs.  Some REITs had previously bypassed certain REIT requirements,
including the 95% Income Test, by pairing or stapling REIT shares with
management Trust shares. These shares remained legally separate, but were
traded as a pair. The Tax Reform Act of 1984 changed the law governing REITs,
and specified that entities could no longer operate as stapled REITs.  However,
the law grandfathered several entities which already were operating as stapled
REITs. President Clinton has also proposed that Code Section 856(c)(5)(B) be
amended to prohibit REITs from holding stock possessing more than 10 percent of
the vote or value of all classes of stock of a corporation. Further, another
Clinton proposal would impose an additional requirement for REIT qualification.
Specifically, under the Clinton proposal, no person could own stock of a REIT
possessing more than 50% of the total combined voting power of all classes of
voting stock, or more than 50% of the total value of shares of all classes of
stock.

FAILURE TO QUALIFY

         If the Trust fails to qualify for taxation as a REIT in any taxable
year, and the relief provisions do not apply, the Trust will be subject to tax
(including any applicable alternative minimum tax) on its taxable income at
regular corporate rates. Distributions to shareholders in any year in which the
Trust fails to qualify will not be deductible by the Trust nor will they be
required to be made. In such event, to the extent of current and accumulated
earnings and profits, all distributions to shareholders will be taxable as
ordinary income, and, subject to certain limitations of the Code, corporate
distributees may be eligible for the dividends received deduction. Unless
entitled to relief under specific statutory provisions, the Trust will also be
disqualified from taxation as a REIT for the four taxable years following the
year during which qualification was lost. It is not possible to state whether
in all circumstances the Trust would be entitled to such statutory relief.

TAXATION OF SHAREHOLDERS

         Distributions by the Trust of net investment income will be taxable to
shareholders as ordinary income to the extent of the current or accumulated
earnings and profits of the Trust. Distributions of net capital gain, if any,
designated by the Trust as capital gain dividends generally will be taxable to
shareholders as long-term capital gain, regardless of the length of time the
Common Shares have been held by the shareholders. However, corporate
shareholders may be required to treat up to 20% of certain capital gain
dividends as ordinary income pursuant to Section 291 of the Code. All
distributions are taxable, at least to the extent of the current or accumulated
earnings and profits of the Trust, whether received in cash or invested in
additional Common Shares. Dividends declared by the Trust in October, November
or December payable to shareholders of record on a date in such a month and
paid during the following January will be treated as having been received by
shareholders on December 31 in the year in which such dividends were declared.
Income (including dividends) from the Trust normally will be characterized as
"portfolio" income (as opposed to "passive" income) for purposes of the tax
rules governing "passive" activities; accordingly, passive losses of the
shareholder may not be used to offset income derived by the shareholder from
the Trust.





                                       21
   23
         None of the distributions from the Trust (as a REIT) received by
corporate shareholders, whether characterized as ordinary income or capital
gain, will qualify for the dividends received deduction generally available to
corporations.

         The Trust may be required to withhold and remit to the Service 31% of
the dividends paid to any shareholder who (a) fails to furnish the Trust with a
properly certified taxpayer identification number, (b) has under reported
dividend or interest income to the Service or (c) fails to certify to the Trust
that he is not subject to backup withholding. Any amount paid as backup
withholding will be creditable against the shareholder's income tax liability.
The Trust will report to its shareholders and the Service the amount of
dividends paid during each calendar year and the amount of any tax withheld.

         In general, any gain or loss realized upon a taxable disposition of
Common Shares of the Trust or upon receipt of a liquidating distribution by a
shareholder who is not a dealer in securities will be treated as long-term
capital gain or loss if the Common Shares have been held for more than one year
and as short-term capital gain or loss if the Common Shares have been held for
one year or less. The Taxpayer Relief Act of 1997 has changed the tax rates and
holding periods applicable to long-term capital gains of individuals. In
general, under applicable provisions of the Taxpayer Relief Act of 1997, which
are generally effective for taxable years ending after May 1, 1997, the maximum
tax rate applicable to net capital gains of individuals realized upon the sale
of property held for 18 months or more is 20% (10% for individuals in a tax
bracket below 28%), and the maximum tax rate on net capital gains of
individuals realized upon the sale of property for more than one year and for
not more than 18 months is 28%. The Taxpayer Relief Act of 1997 does not affect
the taxation of a corporation's capital gains. Because the tax rates and
applicable holding periods will vary depending upon a shareholder's individual
circumstances, investors should consult their own tax advisers concerning the
effect of these Taxpayer Relief Act of 1997 changes. If, however, the
shareholder receives any capital gain dividends with respect to Common Shares
held six months or less, any loss realized upon a taxable disposition of such
Common Shares shall, to the extent of such capital gain dividends, be treated
as a long-term capital loss. All or a portion of any loss realized upon a
taxable disposition of Common Shares of the Trust may be disallowed if other
Common Shares of the Trust are purchased (under a dividend reinvestment plan or
otherwise) within 30 days before or after the disposition.

TAXATION OF TAX-EXEMPT SHAREHOLDERS

         Except as noted below, based upon a revenue ruling issued by the
Service, dividend distributions by the Trust to a shareholder that is a
tax-exempt entity should not constitute "unrelated business taxable income"
("UBTI"), provided that the tax-exempt entity has not financed the acquisition
of its Common Shares with "acquisition indebtedness" within the meaning of the
Code and the Common Shares are not otherwise used in an unrelated trade or
business of the tax-exempt entity. However, if a tax-exempt entity borrows
money to purchase its Common Shares, a portion of its income from the Trust
will constitute UBTI pursuant to the "debt-financed property" rules of the
Code.  Furthermore, social clubs, voluntary employee benefit associations,
supplemental unemployment benefit trusts, and qualified group legal service
organizations that are exempt from taxation under Code Sections 501(c)(7), (9),
(17) and (20), respectively, are subject to different UBTI rules, which
generally will require them to characterize distributions from the Trust as
UBTI. Also, it should be noted that dividend distributions by a REIT to an
exempt organization that is a private foundation should constitute investment
income for purposes of the excise tax on net investment income of private
foundations imposed by Section 4940 of the Code. If an employee trust qualified
under Code Section 401(a) (a "qualified trust") owns more than 10% by value of
the Common Shares in the Trust at any time during a tax year, then a portion of
the dividends paid by the Trust to such trust may be treated as UBTI, but only
if (i) the Trust would not have qualified as a REIT but for the provisions of
the Code which "look through" such a qualified trust for purposes of
determining ownership of a REIT and (ii) at least one qualified trust holds
more than 25% (by value) of the Common Shares in the Trust or one or more
qualified trusts (each of which holds more than 10% of the Common Shares) hold
in the aggregate more than 50% (by value) of the Common Shares. If the Trust
were treated as a "taxable mortgage pool," a substantial portion of the
dividends paid to a tax-exempt shareholder may be UBTI. Although the Trust does
not believe that the Trust, or any portion of its assets will be treated as a
taxable mortgage pool, no assurance can be given that the Service might not
successfully maintain that such a taxable mortgage pool exists.





                                       22
   24
         Because of the complexity and variations of the UBTI rules, tax-exempt
entities should consult their own tax advisers.

TAXATION OF FOREIGN SHAREHOLDERS

         The rules governing United States Federal income taxation of
nonresident alien individuals, foreign corporations, foreign partnerships and
other foreign shareholders (collectively, "non-U.S. shareholders") are complex
and no attempt will be made herein to provide more than a summary of such
rules. Prospective non-U.S. shareholders should consult with their own tax
advisers to determine the impact of Federal, state and local income tax laws
with regard to an investment in Common Shares, including any reporting
requirements.

         Distributions that are not attributable to gain from sales or
exchanges by the Trust of "United States Real Property Interests" and not
designated by the Trust as capital gain dividends will be treated as dividends
of ordinary income to the extent that they are made out of current or
accumulated earnings and profits of the Trust. Generally, such distributions
will be subject to a U.S. withholding tax equal to 30% of the gross amount of
the distribution unless an applicable tax treaty reduces or eliminates that
tax. However, if income from the investment in the Common Shares is treated as
effectively connected with the non-U.S. shareholder's conduct of a United
States trade or business, the non- U.S. shareholder generally will be subject
to a tax at graduated rates, in the same manner as U.S. shareholders are taxed
with respect to such dividends (and may also be subject to the 30% branch
profits tax in the case of a shareholder that is a foreign corporation). The
Trust expects to withhold United States income tax at the rate of 30% on the
gross amount of any such dividends made to a non-U.S. shareholder unless (a) a
lower treaty rate applies and the non-U.S.  shareholder files an IRS Form 1001
or (b) the non-U.S. shareholder files an IRS Form 4224 with the Trust claiming
that the distribution is effectively connected income. Any distributions in
excess of current and accumulated earnings and profits of the Trust will not be
taxable to a non-U.S. shareholder to the extent that they do not exceed the
adjusted basis of the shareholder's Common Shares, but rather will reduce the
adjusted basis of such Common Shares. To the extent that such distributions
exceed the adjusted basis of a non-U.S. shareholder's Common Shares, they will
give rise to tax liability if the non-U.S. shareholder would otherwise be
subject to tax on any gain from the sale or disposition of his Common Shares,
as described below. If it cannot be determined at the time a distribution is
made whether or not such distribution will be in excess of current and
accumulated earnings and profits, the distributions will be subject to
withholding at the same rate as dividends. However, amounts thus withheld are
refundable if it subsequently is determined that such distribution was, in
fact, in excess of current and accumulated earnings and profits of the Trust.

         For any year in which the Trust qualifies as a real estate investment
trust, distributions that are attributable to gain from sales or exchanges by
the Trust of "United States real property interests" will be taxed to a
non-U.S. shareholder under the provisions of the Foreign Investment in Real
Property Tax Act of 1980, as amended ("FIRPTA"). Under FIRPTA, these
distributions are taxed to a non-U.S. shareholder as if such gain were
effectively connected with a United States business. Non-U.S. shareholders
would thus be taxed at the normal capital gain rates applicable to U.S.
shareholders (subject to applicable alternative minimum tax). Also,
distributions subject to FIRPTA may be subject to a 30% branch profits tax in
the hands of a foreign corporate shareholder not entitled to treaty exemption.
The Trust is required by applicable Treasury Regulations to withhold 35% of any
distribution that could be designated by the Trust as a capital gain dividend
to the extent that such capital gain dividends are attributable to the sale or
exchange by the Trust of United States real property interests. This amount is
creditable against the non- U.S. shareholder's Federal tax liability. Fixed
rate mortgage loans will not normally be classified as "United States real
property interests."

         Gain recognized by a non-U.S. shareholder upon a sale of Common Shares
generally will not be taxed under FIRPTA if the Trust is a "domestically
controlled real estate investment trust," defined generally as a real estate
investment trust in which at all times during a specified testing period less
than 50% in value of the Common Shares were held directly or indirectly by
non-U.S. persons. Additionally, gain recognized by a non-U.S. shareholder upon
a sale of Common Shares generally will not be taxed under FIRPTA unless the
shareholder beneficially owns more than 5% of the total fair market value of
the Common Shares at any time during the shorter of the five-year period ending
on the date of disposition or the period during which the shareholder held the
Common Shares. Gain not subject to





                                       23
   25
FIRPTA will be taxable to a non-U.S. shareholder if (a) investment in the
Common Shares is effectively connected with the non-U.S. shareholder's United
States trade or business, in which case the non-U.S. shareholder will be
subject to the same treatment as U.S. shareholders with respect to such gain or
(b) the non-U.S. shareholder is a nonresident alien individual who was present
in the United States for 183 days or more during the taxable year, in which
case the nonresident alien individual will be subject to a 30% tax on his U.S.
source capital gains. If the gain on the sale of Common Shares becomes subject
to taxation under FIRPTA, the non-U.S. shareholder will be subject to the same
treatment as U.S. shareholders with respect to such gain (subject to applicable
alternative minimum tax and a special alternative minimum tax in the case of
nonresident alien individuals).

         Subject to the provisions of any tax treaty that may exist between the
United States and the country in which the foreign holder is domiciled at the
time of his death, an individual foreign shareholder who owns Common Shares at
the time of his death will have the Common Shares subject to Federal estate
tax. The federal estate tax will be assessed on the fair market value of such
Common Shares at the time of the foreign holder's death.

OTHER TAXATION

         Tax treatment of the Trust and its shareholders under tax laws other
than those governing federal income tax may differ substantially from the
Federal income tax treatment described in this summary. CONSEQUENTLY, EACH
PROSPECTIVE SHAREHOLDER SHOULD CONSULT WITH HIS OWN TAX ADVISER WITH REGARD TO
THE STATE, LOCAL AND OTHER TAX CONSEQUENCES (OTHER THAN FEDERAL TAX
CONSEQUENCES) OF AN INVESTMENT IN THE TRUST.

Managers and officers for liabilities arising under the Securities Act is
against public policy and is unenforceable pursuant to Section 14 of the
Securities Act.

ITEM 15. INDEMNIFICATION OF TRUST MANAGERS AND OFFICERS.

         Subsection (B) of Section 9.20 of the Texas Real Estate Investment
Trust Act, as amended (the "Texas REIT Act"), empowers a real estate investment
trust to indemnify any person who was, is, or is threatened to be made a named
defendant or respondent in any threatened, pending, or completed action, suit,
or proceeding, whether civil, criminal, administrative, arbitrative, or
investigative, any appeal in such an action, suit, or proceeding, or any
inquiry or investigation that can lead to such an action, suit or proceeding
because the person is or was a trust manager, officer, employee or agent of the
real estate investment trust or is or was serving at the request of the real
estate investment trust as a trust manager, director, officer, partner,
venturer, proprietor, trustee, employee, agent, or similar functionary of
another real estate investment trust, corporation, partnership, joint venture,
sole proprietorship, trust, employee benefit plan, or other enterprise against
expenses (including court costs and attorney fees), judgments, penalties, fines
and settlements if he conducted himself in good faith and reasonably believed
his conduct was in or not opposed to the best interests of the real estate
investment trust and, in the case of any criminal proceeding, had no reasonable
cause to believe that his conduct was unlawful.

         The Texas REIT Act further provides that, except to the extent
otherwise permitted by the Texas REIT Act, a person may not be indemnified in
respect of a proceeding in which the person is found liable on the basis that
personal benefit was improperly received by him or in which the person is found
liable to the real estate investment trust.  Indemnification pursuant to
Subsection (B) of Section 9.20 of the Texas REIT Act is limited to reasonable
expenses actually incurred and may not be made in respect of any proceeding in
which the person has been found liable for willful or intentional misconduct in
the performance of his duty to the real estate investment trust.

         Subsection (C) of Section 15.10 of the Texas REIT Act provides that a
trust manager shall not be liable for any claims or damages that may result
from his acts in the discharge of any duty imposed or power conferred upon him
by the real estate investment trust, if, in the exercise of ordinary care, he
acted in good faith and in reliance upon information, opinions, reports, or
statements, including financial statements and other financial data, concerning
the real estate investment trust, that were prepared or presented by officers
or employees of the real estate investment trust, legal counsel, public
accountants, investment bankers, or certain other professionals, or a committee
of trust manager of which the trust manager is not a member. In addition, no
trust manager shall be liable to the real estate investment trust for any act,
omission, loss, damage, or expense arising from the performance of his duty to
a real estate investment trust, save only for his own willful misfeasance,
willful malfeasance or gross negligence.

         The Declaration of Trust provides that the Trust shall indemnify every
Indemnitee (as defined below) against all judgments, penalties, fines, amounts
paid in settlement and reasonable expenses actually incurred by the Indemnitee
in connection with any Proceeding (as defined in the Declaration of Trust) in
which Indemnitee was, is, or is threatened to be named defendant or respondent
or called as a witness, by reason of his serving or having served in various
capacities for the Trust if it is determined that the Indemnitee conducted
himself in good faith, reasonably believed that his conduct was in the Trust's
best interests (or, in certain cases, not opposed to the Trust's best
interests) and, in the case





                                      II-1
   29
of any criminal proceeding, had no reasonable cause to believe that his conduct
was unlawful.  For purposes of the Declaration of Trust, "Indemnitee" shall
mean (i) any present or former Trust Manager or officer of the Trust; (ii) any
person who while serving in any of such capacities served at the Trust's
request as a director, officer, partner, venturer, proprietor, Trust Manager,
employee, agent or similar functionary of another REIT or other enterprise; and
(iii) any person nominated or designated by the Board of Trust Managers or any
committee thereof to serve in any of the capacities referred to in the
preceding clauses (i) or (ii).

         Pursuant to indemnification agreements entered into between the Trust
and each of its Trust Managers and executive officers, the Trust has agreed to
indemnify such Trust Managers and executive officers for certain liabilities,
including liabilities under the Securities Act of 1933.

ITEM 17.  UNDERTAKINGS.

         (a)     The undersigned Registrant hereby undertakes:

                 1.       To file, during any period in which offers or sales
         are being made, a post-effective amendment to this registration
         statement:

                          (i)       To include any prospectus required by
                 Section 10(a)(3) of the Securities Act of 1933;

                          (ii)      To reflect in the prospectus any facts or
                 events arising after the effective date of the registration
                 statement (or the most recent post-effective amendment
                 thereof) which, individually or in the aggregate, represent a
                 fundamental change in the information set forth in the
                 registration statement. Notwithstanding the foregoing, any
                 increase or decrease in volume of securities offered (if the
                 total dollar value of securities offered would not exceed that
                 which was registered) and any deviation from the low or high
                 end of the estimated maximum offering range may be reflected
                 in the form of prospectus filed with the Commission pursuant
                 to Rule 424(b) if, in the aggregate, the changes in volume and
                 price represent no more than 20 percent change in the maximum
                 aggregate offering price set forth in the "Calculation of
                 Registration Fee" table in the effective registration
                 statement.

                          (iii)     To include any material information with
                 respect to the plan of distribution not previously disclosed
                 in the registration statement or any material change to such
                 information in the Registration statement;

         provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not
         apply if the registration statement is on Form S-3, form S-8 or Form
         F-3, and the information required to be included in a post-effective
         amendment by those paragraphs is contained in periodic reports filed
         with or furnished to the Commission by the registrant pursuant to
         Section 13 or 15(d) of the Securities Exchange Act of 1934 that are
         incorporated by reference in the registration statement.

                 2.       That, for the purpose of determining any liability
         under the Securities Act of 1933, each such post-effective amendment
         shall be deemed to be a new registration statement relating to the
         securities offered





                                      II-3
   31
         therein, and the offering of such securities at that time shall be
         deemed to be the initial bona fide offering thereof.

                 3.       To remove from registration by means of a
         post-effective amendment any of the securities being registered which
         remain unsold at the termination of the offering.

         (b)     The undersigned registrant hereby undertakes that, for
purposes of determining any liability under the Securities Act of 1933, each
filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of
the Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to Section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

         (c)     Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to trust managers, directors, officers
and controlling persons of the registrant pursuant to the foregoing provisions
or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public
policy as expressed in the Act and is, therefore, unenforceable. In the event
that a claim for indemnification against such liabilities (other than in
payment by the registrant of expenses incurred or paid by a trust manager,
director, officer or controlling person in the successful defense of any
action, suit or proceeding) is asserted against the registrant by such trust
manager, director, officer or controlling person in connection with the
securities being registered, the registrant will, unless in the opinion of its
counsel the matter has been settled by controlling precedent, submit to a court
of appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Act and will be governed by the final
adjudication of such issue.

         Pursuant to the requirements of the Securities Act of 1933, the
registrant certifies that it has reasonable grounds to believe that it meets
all of the requirements for filing on Form S-3 and has duly caused this
registration statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Dallas, State of Texas, on the 14th of May,
1998.
