Results of Operations and Changes in Financial Conditions
---------------------------------------------------------

(a) General
-----------

As of June 30, 2000, the developed properties owned by the Partnership were 100%
occupied, whereas they were 99.8% occupied at June 30, 1999.  Gross revenues of
the Partnership were $924,717 for the six months ended June 30, 2000, as
compared to $829,668 for the six months ended June 30, 1999.  The increase was
attributable primarily to the equity in income of joint venture due to the
increase in gross revenues at the ABB property which is now 100% occupied and
income from the parking lot expansion at the Iomega property.  Expenses of the
Partnership decreased to $50,907 for the six months ended June 30, 2000, as
compared to $62,686 for the same period in 1999, as a result of decreased costs
primarily in administrative salaries. As a result, net income of the Partnership
was $873,810 for the six months ended June 30, 2000, as compared to a net income
of $766,982 for the six months ended June 30, 1999.

The Partnership's net cash used in operating activities decreased to $(50,907)
for 2000, as compared to $(61,590) for 1999, which is due primarily to the
decrease in expenses.  Net cash provided by investing activities decreased to
$1,326,243 from $1,343,591 because of the decreased distributions received from
joint ventures.  Net cash used in financing activities decreased from $1,301,811
to $1,374,044 due to the distribution to partners from accumulated earnings.
Cash and cash equivalents decreased from $228,636 to $75,719 for the same period
in 2000.

The Partnership's distributions per unit for Class A Unit holders for the second
quarter of 2000 was $0.23 per weighted average unit compared to $0.23 for the
same period in 1999.  No cash distributions were made to the Limited Partners
holding Class B Units or to the General Partners.  The Partnership currently
anticipates that distributions will continue to be paid on a quarterly basis on
a level at least consistent with 1999 distributions.

The Partnership expects to continue to meet its short-term liquidity
requirements generally through net cash provided by operations which the
Partnership believes will continue to be adequate to meet both operating
requirements and distributions to limited partners.

The Partnership expects to make future real estate investments, directly or
through investments in joint ventures, from limited partners' capital
contributions.  As of June 30, 2000, the Partnership was holding $73,604
available for investment in properties.

Subsequent Event
----------------

On June 15, 2000, the Fund VIII-IX-REIT Joint Venture was formed between Wells
OP and Fund VIII and Fund IX Associates, a Georgia joint venture partnership
between the Partnership and Wells Real Estate Fund VIII, L.P.  On July 1, 2000,
the Fund VIII-Fund IX Joint Venture transferred its interest in the Bake Parkway
Property, (formerly the "Matsushita Building"), into the Fund VIII-IX-REIT Joint
Venture.  The Bake Parkway Building is a two-story office building containing
approximately 65,006 rentable square feet on a 4.4 acre tract of land in Irvine,
California.

                                       9
<PAGE>

A 42-month lease for the entire Bake Parkway Building has been signed by Quest
Software, Inc.  Quest is a publicly traded corporation that provides software
database management and disaster recovery for its clients.

Construction of tenant improvements regarding the Quest lease is anticipated to
cost approximately $1,250,000 and will be funded by Wells OP.

Matsushita Avionics and the Fund VIII-IX Joint Venture have entered into a Lease
and Guaranty Termination Agreement dated February 18, 1999. Matsushita Avionics
vacated its current space in January 2000, and was relieved of any of its
obligations under the existing lease. In consideration for the Fund VIII-IX
Joint Venture releasing Matsushita Avionics from its obligations under the
existing lease and thereby allowing Wells OP to enter into the Matsushita lease
with Matsushita Avionics, Wells OP entered into a rental income guaranty
agreement dated as of February 18, 1999, whereby Wells OP guaranteed the Fund
VIII-IX Joint Venture that it will receive rental income on the existing
building at least equal to the rent and building expenses that the Fund VIII-IX
Joint Venture would have received over the remaining term of the Matsushita
lease.

Operating expenses are negative due to actual expenses being lower than Wells OP
operating expense reimbursements in 2000, which is based on budget and will be
reconciled later this year.  Management and leasing expense will not be paid
until the building is re-leased and occupied.

Rental income, depreciation and management and leasing fees remain relatively
stable while other operating expenses increased for the six months ended June
30, 2000, as compared to the same period in 1999, due primarily to differences
in the annual adjustment for common area maintenance billing to the tenant.
Tenants are billed an estimated amount for the current year common area
maintenance which is then reconciled the following year and the difference
billed to the tenant.  Property taxes increased substantially in 1998, but the
tenant was not billed until the annual adjustment was computed in the second
quarter of 1999.

common area maintenance billings to the tenants were increased in 2000 to offset
1999 underpayments.

</TABLE>

Rental income increased in 2000, over 1999, due primarily to the increased
occupancy level of the property.  Total expenses decreased due to a decrease in
depreciation expense.  This decrease resulted from an accelerated depreciation
on tenant improvement for a short term lease in 1999 for 23,092 square feet.
Other operating expenses are negative due to an offset of tenant reimbursements
in operating costs, as well as management and leasing fee reimbursements.
Tenants are billed an estimated amount for the current year common area
maintenance which is then reconciled the following year and the difference
billed to the tenant.  Net income and cash distributions increased in 2000 over
1999, due to a combination of increased rental income and decreased expenses.

The Partnership's ownership interest  increased due to the contribution of
additional cash fundings to the IX-X-XI-REIT Joint Venture in the first quarter
of 2000.

</TABLE>

Net income decreased in 2000, as compared to 1999, due to an overall increase in
expenses.  Operating expenses increased significantly due to the rise in real
estate taxes, which stemmed from the revaluation of the property by Boulder
County authorities in 1999.  A later reduction in taxes due to an appeal in 2000
was offset by a common area maintenance  reimbursement credit to the tenant.

Cash distributions have decreased largely because of the decrease in net income.
The Partnership's ownership interest increased due to additional cash fundings
to the IX-X-XI-REIT Joint Venture in the first quarter.

</TABLE>

Rental income increased due to a tenant occupying additional space previously
leased to another tenant at a lower rate.  Other operating expenses are negative
due to an offset of tenant reimbursements in operating costs, as well as
management and leasing fee reimbursement.  Tenants are billed an estimated
amount for current year common area maintenance which is then reconciled the
following year and the difference billed to the tenants.  Due to these CAM
reimbursements, management and leasing fees increased since these fees are
charged only on actual receipts received.

Cash distributions and net income allocated to the Partnership for the quarter
ended June 30, 2000, increased in 2000 over 1999, due to an increase in net
income.  The Partnership's ownership interest in the Fund IX-X-XI-REIT Joint
Venture increased due to additional fundings by the Partnership to the Joint
Venture.

</TABLE>


Rental income, depreciation and management and leasing fees remained stable in
2000, as compared to 1999, while other operating expenses are slightly lower,
due primarily to a one-time charge for consulting fees in 1999, which did not
occur in 2000.

The Partnership's ownership interest in the Fund IX-X-XI-REIT Joint Venture
increased due to additional fundings by the Partnership to the Joint Venture in
the first quarter.

</TABLE>

Rental income increased in 2000, as compared to 1999, due to the completion of
the parking lot complex in the second quarter of 1999.  Total expenses increased
in 2000, over 1999 due to an increase in depreciation and real estate tax
expenses relating to the new parking lot.  Cash distributions increased in 2000,
over 1999, due primarily to the increase in net income.

The Partnership's ownership interest in the Fund IX-X-XI-REIT Joint Venture
increased due to additional funding by the Partnership to the Joint Venture in
the first quarter.
