                  PROPERTY AND PARTNERSHIP MANAGEMENT AGREEMENT

        THIS PROPERTY MANAGEMENT AGREEMENT is entered into effective as of the
28th day of January, 1999, by and between HARTMAN REIT OPERATING PARTNERSHIP,
L.P., a Delaware limited partnership (hereinafter called "Owner"), and HARTMAN
MANAGEMENT, INC., (hereinafter called "Manager"),

                                   WITNESSETH

        WHEREAS, Owner is the owner of the properties described in Schedule A
attached hereto (collectively, the "Properties"); and

        WHEREAS, Owner wishes to obtain the benefits of Manager's expertise in
the field of real estate management by relinquishing to Manager control in the
operation, direction, management and supervision of the Properties, subject to
the terms and provisions of this Agreement, and Manager for a fee agrees to
assume said control and discretion in the operation, direction, management and
supervision of the Properties on behalf of Owner.

        NOW, THEREFORE, in consideration of the mutual covenants herein
contained and of other good and valuable consideration, the parties hereto agree
as follows:

                                    ARTICLE 1

                                   APPOINTMENT

        Owner contracts with Manager to manage, operate, direct and supervise
the Properties, as well as all other properties acquired by Owner from time to
time, on behalf of Owner and to provide services as required under this
Agreement.

                                      TERM

        Subject to and upon the terms and conditions set forth in this Agreement
(including without limitation Article 12), the term of this Agreement shall
commence on February 1, 1999, and shall automatically renew for successive one
year terms unless terminated in writing by either party at least thirty (30)
days prior to the expiration of a previous term.

                                    ARTICLE 3

                                  RELATIONSHIP

        Manager shall at all times be the independent contractor of Owner and
not the employee or agent of Owner. Manager shall have no right or power to
contract with third parties for, on behalf of, or in the name of Owner or
otherwise to bind Owner. Except as expressly provided herein to the contrary,
Owner agrees to be responsible for and shall reimburse Manager for all costs,
expenses and disbursements reasonably and properly incurred by Manager in
accordance with the provisions of this Agreement in providing management and
operational services hereunder, such as, but not limited to, contracts for
cleaning services, contracts for landscaping or maintenance services and orders
for supplies and equipment, and Owner agrees to indemnify and hold Manager
harmless from and against the same. Owner agrees to name Manager as an
additional insured on all comprehensive general liability insurance maintained
by Owner and relating to the Properties, and Owner shall pay the cost of any
comprehensive general liability insurance policy maintained by Manager and
relating to the Properties, but only to the extent that such is reasonable, is
not duplicate of insurance maintained by Owner (but only if such insurance of
Owner names Manager as an additional insured), and is approved by Owner.

                                  ASSIGNABILITY

        Manager shall not assign this Agreement or any rights hereunder, nor
shall Manager delegate its duties hereunder, without the prior written consent
of Owner; provided, however, Manager may assign this Agreement and delegate its
duties to any entity which succeeds to all or substantially all of the assets of
Manager and/or to any entity which is owned or controlled by Allen R. Hartman,
and Manager may delegate certain of its duties to its employees, agents and
contractors as contemplated by the provisions of this Agreement.

                                    ARTICLE 5

                               SERVICES OF MANAGER

        5.1     Manager shall manage, operate and maintain the Properties in a
manner normally associated with the management and operation of properties that
are similar in size, scope and use as the Properties. Manager shall at all times
deal with third parties (whether or not affiliated with Manager) at arms' length
and in Owner's interest at all times.

        5.2     Manager shall have in its employ at all times a sufficient
number of capable employees to enable it to properly, adequately, safely and
economically manage, operate and maintain the Properties. All matters pertaining
to the employment, supervision, compensation, promotion and discharge of such
employees are the responsibility of Manager. Manager is in all respects the
employer of such employees, but Owner may require that any particular employee
or employees be removed from duty with respect to the Properties, if Owner
reasonably deems such employee or employees to be incompetent, careless,
insubordinate or otherwise objectionable. Manager shall fully comply with all
applicable laws and regulations

                                       -3-

<PAGE>

having to do with workman's compensation, social security, unemployment
insurance, hours of labor, wages, working conditions, and other
employer-employee related subjects. All employees engaged by Manager shall be
the employees of Manager and not of Owner.

        5.3     Manager shall prepare and submit to Owner a proposed operating
budget for the Properties for the management and operation of the Properties for
the forthcoming calendar year (or in the case of the first calendar year in
which the term hereof commences, the remainder of such year if it is not a full
calendar year). The first such budget shall be submitted to Owner within thirty
(30) days after the commencement of the term of this Agreement and in the future
a subsequent proposed budget shall be delivered to Owner no later than November
1 of each calendar year. By November 1 of each calendar year, Manager will
submit to Owner a summary of the actual (through September 30) and projected
(for the full year) results of management and operation of the Properties for
such calendar year. Owner will consider the proposed budgets and then will
consult with Manager within thirty (30) days after they are submitted in order
to agree on an "Approved Operating Budget". Manager shall have the right from
time to time during each calendar year to submit revised budgets to Owner, and
Owner shall endeavor to approve the same or revisions thereto as Owner and
Manager may deem proper and as promptly as practicable.

Manager agrees to use diligence and to employ all reasonable efforts to ensure
that the actual costs (net of amounts, if any, recovered from third parties) of
maintaining and operating the Properties shall not exceed the approved budget
pertaining thereto.

        5.4     Manager shall use diligent efforts to collect all rents
(including billings resulting from tenant participation in operating expenses,
taxes and common area maintenance

                                       -4-

charges) and other charges which may become due at any time from any tenant or
from others for services provided in connection with or for the use of the
Properties or any portion thereof. Manager shall identify any amounts due to
Owner from miscellaneous services provided to tenants or the public including,
but not limited to, parking income, tenant storage, and retail income. All
monies so collected shall be deposited in the Receipts Account. Manager cannot
and may not terminate any lease, lock out a tenant, institute a suit for rent or
for use and occupancy, or institute proceedings for recovery of possession of
any properties, without the prior written approval of Owner. In connection with
such suits or proceedings only legal counsel designated by Owner shall be
retained. The estimated costs of legal services to be incurred in bringing such
approved suit or proceeding shall be submitted to Owner for its approval.
Manager shall not write off any rental income of more than $1,000 for any single
tenant without the prior written approval of Owner.

        5.5     Manager shall act as leasing manager for the Properties and be
responsible for the leasing activities of the Properties, including the
development of a marketing program and leasing guidelines (including rental
rates, lease terms, and similar items). It is understood that a marketing
program and leasing guidelines will be submitted to Owner prior to November 1 of
each year, and Owner shall endeavor to approve a marketing program and leasing
guidelines within thirty (30) days after a submission is made by Manager. Once
the marketing program and leasing guidelines are approved by Owner, Manager may
act without further approvals as long as Manager acts within the approved
guidelines of the marketing program and leasing guidelines. It is understood
that Owner is the only signatory authority for the execution of all lease and
related

                                       -5-

<PAGE>

leasing documents and Manager shall not represent to the contrary to prospective
tenants and other parties.

        5.6     Manager shall institute and supervise all ordinary and
extraordinary repairs, decorations and alterations, including the administration
of a preventative maintenance program for all mechanical, electrical and
plumbing systems and equipment, provided that such (unless the same relate to
emergencies) are included in an Approved Operating Budget.

        5.7     Manager shall institute and supervise all operational activities
of the Properties (such as the following, but not limited to this listing):

        (a)     Supervision of the cleaning;

        (b)     Supervision of the security on behalf of Owner;

        (c)     Supervision of any landscaping;

        (d)     Supervision of the window washing;

        (e)     Responsibility for and supervision of the central plant and
    other H.V.A.C. equipment;

        (i)     Responsibility for making arrangements for and administering

        (j)     Any other activity expedient to the normal operation of
    properties similar to the Properties.

        As used herein, "supervise" and "supervision" shall also include
responsibility for the particular task to the extent the Owner so directs and
provides the funds therefor.

        5.8     Manager shall obtain and verify bills for real estate and
personal property taxes, improvement assessments and other like charges which
are or may become liens against any portion of the Properties and recommend
payment or appeal as its best judgment may decide. If and when received by
Manager, Manager shall forward such bills to Owner in such time to permit Owner
to avoid penalty for late payment or to permit Owner to take advantage of
discounts and upon the written direction of Owner, Manager shall pay such bills
from the Disbursement Account. Manager shall not make any payments on account of
any ground lease, mortgage, deed of trust or other security instrument, if any,
affecting any Properties unless such payments are included in the Approved
Operating Budget.

        5.9     Manager shall operate the Properties in compliance with any
ground lease, space lease, mortgage, deed of trust or other security instruments
affecting the Properties and of which Manager has knowledge, but Manager shall
not be required to make any payment or incur any liability on account thereof.

        5.10    Manager shall pay all leasing and operating expenses from the

        5.13    Manager shall conduct, from time to time as Manager deems
necessary or as Owner requests, inspections of the Properties and provide Owner
with a written report on its findings to the extent requested by Owner.

        5.14    Manager shall, on behalf of Owner, maintain complete and
identifiable records and files on all matters pertaining to the Properties,

and leases, all of which records and files shall be the property of Owner.

        5.15    Manager shall have competent personnel available at all times

Owner, shall maintain adequate and separate books and records for the Properties
in accordance with acceptable accounting standards for a modified cash basis
accounting method, which shall be supported by sufficient documentation to
ascertain that said entries are properly and accurately recorded, which books
and records shall be the property of Owner. However, any computer software or
other systems of Manager which are used to generate or keep such books and
records shall remain the property of Manager. Such books and records shall
include all information necessary to calculate and to audit amounts contained
therein and shall otherwise comply with the requirements of the documents
referred to in Section 5.9 hereof. Such books and records

                                       -8-

<PAGE>

shall be maintained by Manager at the Properties or at such other location as
may be mutually agreed upon in writing. Manager shall utilize procedures to
attempt to ensure such control over accounting and financial transactions as is
reasonably required to protect Owner's assets from theft, error or fraudulent
activity.

        5.18    (b)     Manager shall maintain records of, and furnish customary
(as requested) reports summarizing, all transactions occurring from the first
day of the prior calendar quarter to the last day of the prior calendar quarter.
These reports are to be received by Owner no later than thirty (30) calendar
days after the end of the above described accounting period (or sooner if
necessary for Owner or any partner of Owner to comply with governmental
requirements of which Manager is given reasonable advance notice) and must
report financial details which Owner may request. Reports on vacancies and other
matters pertaining to the management, operation, and maintenance of the
Properties will be provided on an annual basis. The reports shall include a
comparison of quarterly and year-to-date actual income and expense with the
Approved Operating Budget for the Properties.

        5.18    (c)     As additional support to the quarterly financial

compliance with Federal, State and Municipal laws, ordinances, regulations and
orders relative to the leasing, use, operation, repair and maintenance of the
Properties and with the rules, regulations or orders of the local Board of Fire
Underwriters or other similar body. Manager shall promptly remedy any violation
of any such law, ordinance, rules, regulation or order which comes to its
attention, all at Owner's expense. Expenses incurred in remedying violations may
be paid by Manager provided such expenses do not exceed $1,000 in any one
instance. When more than such amount is required or if the violation is one for
which the Property's title holder might be subject to penalty, Manager shall
notify Owner by the end of the next business day to assure that prompt
arrangements may be made to remedy the violation.

        5.20    Notwithstanding anything contained herein to the contrary, in
case of emergency, Manager may make expenditures for repairs and other items
which exceed approved budgets or prior approvals from Owner without prior
written approval if in the reasonable judgment of Manager it is necessary to
prevent damage or injury. Owner must be informed of any such expenditures before
the end of the next business day.

        5.21    Partnership and Company Management. Manager shall perform the
following administrative services for Owner:

        (a)     Forwarding to the partners of Owner, within a reasonable time
    after receipt thereof, all statements, reports and other information to be
    sent to them pursuant to the Limited Partnership Agreement of Owner (the
    "Limited Partnership Agreement") or as required by law; and

        (b)     Forwarding to the partners of Owner, within a reasonable time
    after receipt thereof, checks of Owner, payable to the order of the partners
    of Owner representing cash distributions to be made pursuant to the Limited
    Partnership Agreement. All statements, reports, other information and checks
    that are to be forwarded to the partners of Owner, as aforesaid, shall be
    deemed to have been so forwarded when the same are deposited in the United
    States mail addressed to the addresses set forth in the Owner's records, or
    at such other addresses of which Manager has been notified in writing.

                                    ARTICLE 6

                              MANAGEMENT AUTHORITY

        6.1     Manager's authority is expressly limited to the provisions
provided herein or as may be amended in writing from time to time by Owner and
mutually agreed to and accepted by Manager in writing.

        6.2     The Approved Operating Budget shall constitute an authorization
for Manager to expend money to operate and manage the Properties and Manager may
do so without further approval as long as Manager does not exceed the total
budgeted amount for all budget

                                      -11-

<PAGE>

categories. Whenever the total budgeted amount is (or appears likely to be)
exceeded, a cumulative budget variance and a revised operating budget shall be
presented to Owner for its consideration. Except as expressly permitted in this
Agreement, Manager may not act outside of the Approved Operating Budget until
the revised budget is approved in writing by Owner, which approval Owner will
endeavor to give in a timely manner. Once approved, Manager's authority with the
revised or any additionally revised budgets is the same as that authorized for
the original budget.

        6.3     Any capital expenditures must be specifically authorized by
Owner. With respect to the purchase and installation of capital items, Manager
shall recommend that Owner purchase these items when Manager believes such
purchase to be necessary or desirable. Owner may arrange to purchase and install
the same itself or may authorize Manager to do so subject to prescribed
supervision and specification requirements and conditions. Unless Owner
specifically waives such requirements, either by memorandum or as an amendment
to the contract, all new or replacement capital items exceeding Fifteen Thousand
and No/100 Dollars ($15,000.00) shall be awarded on the basis of competitive
bidding, solicited in the following manner:

        (a)     A minimum of two written bids will be obtained for each purchase
    in excess of $15,000. A minimum of three written bids will be obtained for
    each purchase in excess of $25,000;

        (b)     Each bid will be solicited in a form prescribed by Owner so that
    uniformity will exist in the bid quotes;

        (c)     Manager shall provide Owner with all bid responses accompanied
    by Manager's recommendations as to the most acceptable bid. If Manager
    advises acceptance

                                      -12-

<PAGE>

    of other than the lowest bidder, Manager shall adequately support, in
    writing, its recommendations; and

        (d)     Owner shall be free to accept or reject any and all bids. Owner
    will communicate to Manager in writing its acceptance or rejection of bids.
    Owner may pay for capital expenses from its own resources or may authorize
    payment by Manager out of an appropriate account.

        6.4     Manager shall not enter into any contract with a party
affiliated with or related to Manager for cleaning, maintaining, repairing or
servicing the Properties or any of the constituent parts of the Properties
without the prior written consent of Owner. As a condition to obtaining such
consent, Manager shall supply Owner with a copy of the proposed contract and
shall state to Owner the affiliation or relationship between Manager (or other
person or persons in control of Manager) and the party proposed to supply such
goods or services, or both. Prior to entering into any such contract, whether or
not with an affiliated or related party, Manager shall submit a proposal to
Owner and Owner may veto the same if Owner reasonably deems it to be
unnecessary, wasteful or inappropriate. Any such contract will include prudent
cancellation rights.

        6.5     All leases and related lease documents, all contracts and all
purchases, and all legal documentation related thereto, are to be in the name of
Owner in the form prescribed by Owner and shall be executed by Owner, with the
exception of contracts permitted under Section 6.4 hereof and of purchase orders
related to the purchase of items within approved budgets, which may be executed
by Manager. Owner expressly withholds from Manager any power or authority to
make any structural change in the building or to make any other major
alterations or

                                      -13-

<PAGE>

additions in or to the building or equipment therein, or to incur any expense
chargeable to Owner other than expenses related to exercising the express powers
herein vested in Manager, without the prior written direction of Owner.

                                    ARTICLE 7

                                    INSURANCE

        7.1     Manager will upon written request, obtain in Owner's name and at
Owner's expense and keep in force, in an amount requested by Owner, insurance
against physical damage (e.g. fire and extended coverage endorsement, boiler and
machinery, etc.) and against liability for loss, damage or injury to property or
persons which might arise out of the occupancy, management, operation or
maintenance of the Properties covered by this Agreement. Manager will be covered
as an additional insured in all liability insurance maintained by Owner with
respect to the Properties. Owner shall save Manager harmless from any liability
on account of loss, damage or injury actually insured against by Owner provided
Manager:

        (a)     notifies Owner within twenty-four (24) hours after Manager
    receives notice of any such loss, damage or injury;

        (b)     takes no action (such as admission of liability), and omits no
    actions, which might bar Owner from obtaining any protection afforded by any
    policy Owner may hold or which might prejudice Owner in its defense to a
    claim based on such loss, damage or injury; and

        (c)     agrees that Owner shall have the exclusive right, at its option,
    to conduct the defense to any claim, demand or suit within limits prescribed
    by the policy or policies of insurance.

                                      -14-

<PAGE>

Nothing herein shall be construed as indemnifying Manager against any
intentional tort of Manager or his employees or agents or to indemnify Manager
against any act or omission for which insurance protection is not available;
neither is the foregoing intended to affect the general requirement of this
Agreement that the Properties shall be managed, operated and maintained in a
safe condition and in a proper and careful manner.

        7.2     Manager shall furnish whatever information is requested by Owner
for the purpose of establishing the placement of insurance coverages and shall
aid and cooperate in every reasonable way with respect to such insurance and any
loss thereunder. Owner shall include in its hazard policy covering the
Properties and the personal property, fixtures and equipment located thereon,
and Manager shall include in any fire policies for its furniture, furnishings or
fixtures situated in the Properties, appropriate clauses pursuant to which the
respective insurance carriers shall waive all rights of subrogation (and Owner
and Manager hereby waive all claims against the other) with respect to losses
arising from causes insured against under such policies, even if caused by the
negligence of a party, its agents or employees.

                                    ARTICLE 8

                             OWNER'S RIGHT TO AUDIT

        8.1     Owner reserves the right for Owner's employees or others
appointed by Owner, to conduct examinations, during normal business hours upon
written notice, of the books and records maintained for Owner by Manager no
matter where the books and records are located. Owner also reserves the right to
perform any and all additional audit tests relating to Manager's activities,
either at the Properties or at any office of Manager, provided such audit tests
are related to those activities performed by Manager for Owner.

                                      -15-

<PAGE>

        8.2     Should Owner's employees or appointees discover either
weaknesses in internal control or errors in record keeping, Manager shall
correct such discrepancies either upon discovery or within a reasonable period
of time thereafter. Manager shall inform Owner in writing of the action taken to
correct such audit discrepancies. Any and all such audits conducted either by
Owner's employees or appointees will be at the sole expense of Owner, unless
such audits indicate fraud or gross neglect.

                                    ARTICLE 9

                                  BANK ACCOUNTS

        9.1     Manager shall deposit all rents and other funds collected from
the operation of the Properties, including any and all advance funds, in a bank
account designated by Owner (the "Receipt Accounts") for the Properties in the
name of Owner. The bank shall be informed in writing that the funds are held in
trust for Owner and of the designated representatives of Manager that Owner has
approved as having access to such accounts. If requested by Owner, Manager shall
establish a second account (the "Disbursement Account"). It established, Manager
shall pay the operating expenses of the Properties and any other payments
relative to the Properties as required by the terms of this Agreement (including
Manager's fee under Article 20 hereof) out of the Disbursement Account. Money
shall be transferred from the Receipts Account to the Disbursement Account as
deemed necessary by Manager.

        9.2     Manager shall, on behalf of Owner, maintain detailed records of
all security deposits and such records will be open for inspection by Owner's
employees or appointees.

        9.3     Owner may direct the Manager to change a depository bank or the
depository arrangements.

                                      -16-

<PAGE>

        9.4     Through the use of signature cards, authorized representatives
of Owner shall be permitted access to any and all funds in the bank account
described in Section 9.1. However, Owner and Owner's representative may not draw
against said bank accounts without written communication to Manager. Manager's
authority, and the authority of any designated representative of Manager, to
