Part I

Item 1. Business

General
Southwest Royalties Institutional Income Fund VIII-B, L.P. (the
"Partnership" or "Registrant") was organized as a Delaware limited
partnership on November 30, 1987. The offering of limited partnership
interests began March 31, 1988, reached minimum capital requirements on
July 11, 1988 and concluded on March 31, 1989. The Partnership has no
subsidiaries.

The Partnership has expended its capital and acquired interests in
producing oil and gas properties. After such acquisitions, the Partnership
has produced and marketed the crude oil and natural gas produced from such
properties. In most cases the Partnership purchased royalty or overriding
royalty interests and working interests in oil and gas properties that were
converted into net profits interests or other nonoperating interests. The
Partnership purchased either all or part of the rights and obligations
under various oil and gas leases.

The principal executive offices of the Partnership are located at 407 N.
Big Spring, Suite 300, Midland, Texas, 79701. The Managing General Partner
of the Partnership, Southwest Royalties, Inc. (the "Managing General
Partner") and its staff of 98 individuals, together with certain
independent consultants used on an "as needed" basis, perform various
services on behalf of the Partnership, including the selection of oil and
gas properties and the marketing of production from such properties. H. H.
Wommack, III, a stockholder, director, President and Treasurer of the
Managing General Partner, is also a general partner. The Partnership has
no employees.

Principal Products, Marketing and Distribution
The Partnership has acquired and holds royalty interests and net profit
interests in oil and gas properties located in New Mexico and Texas. All
activities of the Partnership are confined to the continental United
States. All oil and gas produced from these properties is sold to
unrelated third parties in the oil and gas business.

The revenues generated from the Partnership's oil and gas activities are
dependent upon the current market for oil and gas. The prices received by
the Partnership for its oil and gas production depend upon numerous factors
beyond the Partnership's control, including competition, economic,
political and regulatory developments and competitive energy sources, and
make it particularly difficult to estimate future prices of oil and natural
gas.


During 1998 oil prices fell to their lowest daily levels since 1986 and to
their lowest annual average since 1976. In two years, oil prices have been
sliced by more than half. The factors that started the decline in oil
prices in 1997 are the same ones that have kept them down in 1998. It was
believed that there would be continued heavy consumption coming from the
Asian region, but the collapse of their markets late in 1997 carried over
to this year bringing demand down with it. Asian consumption had all but
disappeared in 1998, creating an oversupply of crude oil on the market.
That drop in demand has lasted longer than anyone had anticipated, but
hopes of a recovery abound. Another reason for the continued drop in
prices has been OPEC's unwillingness to completely comply with production
cuts established in March and again in June. Although they have been near
90% compliance at times, they have also been below 70% on a monthly basis.
Even a four-day bombing in December of Iraqi military sites could create
only a one-day rally in oil prices. Crude oil closed December 31, 1998 at
$12.05 per barrel on the NYMEX and posted prices closed at $9.50 per
barrel.

In a year of fairly optimistic expectations for gas prices, the average
price of natural gas wound up declining in 1998 to its lowest level since
1995. Although the nationwide average did remain above $2.00 per MMBTU,
1998's prices were approximately 17% lower than those seen in 1997. The
combination of mild weather throughout the year and a gas storage surplus
both contributed to the low prices. Analysts' predictions for 1999 prices
vary, ranging from a low of $1.87 per MMBTU to a high of $2.40 per MMBTU.
Reduced production throughout the U.S. industry, along with large gas
storage withdrawals during the first weeks of January 1999, are both key
factors in our belief that the 1999 average gas price will remain around
$1.80 per MMBTU level.

Following is a table of the ratios of revenues received from oil and gas
production for the last three years:

Oil Gas

1998 86% 14%
1997 87% 13%
1996 88% 12%

As the table indicates, the majority of the Partnership's revenue is from
its oil production; therefore, Partnership revenues will be highly
dependent upon the future prices and demands for oil.

Seasonality of Business
Although the demand for natural gas is highly seasonal, with higher demand
in the colder winter months and in very hot summer months, the Partnership
has been able to sell all of its natural gas, either through contracts in
place or on the spot market at the then prevailing spot market price. As a
result, the volumes sold by the Partnership have not fluctuated materially
with the change of season.


Customer Dependence
No material portion of the Partnership's business is dependent on a single
purchaser, or a very few purchasers, where the loss of one would have a
material adverse impact on the Partnership. Two purchasers accounted for
74% of the Partnership's total oil and gas production during 1998:
Scurlock Permian LLC for 50%, and Mobil Corporation for 24%. Two
purchasers accounted for 73% of the Partnership's total oil and gas
production during 1997: Scurlock Permian Corporation for 50%, and Mobil
Corporation for 23%. Two purchasers accounted for 77% of the Partnership's
total oil and gas production during 1996: Scurlock Permian Corporation 52%
and Mobil Corporation 25%. All purchasers of the Partnership's oil and gas
production are unrelated third parties. In the event any of these
purchasers were to discontinue purchasing the Partnership's production, the
Managing General Partner believes that a substitute purchaser or purchasers
could be located without undue delay. No other purchaser accounted for an
amount equal to or greater than 10% of the Partnership's sales of oil and
gas production.

Competition
Because the Partnership has utilized all of its funds available for the
acquisition of net profits or royalty interests in producing oil and gas
properties, it is not subject to competition from other oil and gas
property purchasers. See Item 2, Properties.

Factors that may adversely affect the Partnership include delays in
completing arrangements for the sale of production, availability of a
market for production, rising operating costs of producing oil and gas and
complying with applicable water and air pollution control statutes,
increasing costs and difficulties of transportation, and marketing of
competitive fuels. Moreover, domestic oil and gas must compete with
imported oil and gas and with coal, atomic energy, hydroelectric power and
other forms of energy.

Regulation

Oil and Gas Production - The production and sale of oil and gas is subject
to federal and state governmental regulation in several respects, such as
existing price controls on natural gas and possible price controls on crude
oil, regulation of oil and gas production by state and local governmental
agencies, pollution and environmental controls and various other direct and
indirect regulation. Many jurisdictions have periodically imposed
limitations on oil and gas production by restricting the rate of flow for
oil and gas wells below their actual capacity to produce and by imposing
acreage limitations for the drilling of wells. The federal government has
the power to permit increases in the amount of oil imported from other
countries and to impose pollution control measures.


Various aspects of the Partnership's oil and gas activities are regulated
by administrative agencies under statutory provisions of the states where
such activities are conducted and by certain agencies of the federal
government for operations on Federal leases. Moreover, certain prices at
which the Partnership may sell its natural gas production are controlled by
the Natural Gas Policy Act of 1978, the Natural Gas Wellhead Decontrol Act
of 1989 and the regulations promulgated by the Federal Energy Regulatory
Commission.

Environmental - The Partnership's oil and gas activities are subject to
extensive federal, state and local laws and regulations governing the
generation, storage, handling, emission, transportation and discharge of
materials into the environment. Governmental authorities have the power to
enforce compliance with their regulations, and violations carry substantial
penalties. This regulatory burden on the oil and gas industry increases
its cost of doing business and consequently affects its profitability. The
Managing General Partner is unable to predict what, if any, effect
compliance will have on the Partnership.

Industry Regulations and Guidelines - Certain industry regulations and
guidelines apply to the registration, qualification and operation of oil
and gas programs in the form of limited partnerships. The Partnership is
subject to these guidelines which regulate and restrict transactions
between the Managing General Partner and the Partnership.

The Partnership complies with these guidelines and the Managing General
Partner does not anticipate that continued compliance will have a material
adverse effect on Partnership operations.

Partnership Employees
The Partnership has no employees; however the Managing General Partner has
a staff of geologists, engineers, accountants, landmen and clerical staff
who engage in Partnership activities and operations and perform additional
services for the Partnership as needed. In addition to the Managing
General Partner's staff, the Partnership engages independent consultants
such as petroleum engineers and geologists as needed. As of December 31,
1998, there were 98 individuals directly employed by the Managing General
Partner in various capacities.


Item 2. Properties

In determining whether an interest in a particular producing property was
to be acquired, the Managing General Partner considered such criteria as
estimated oil and gas reserves, estimated cash flow from the sale of
production, present and future prices of oil and gas, the extent of
undeveloped and unproved reserves, the potential for secondary, tertiary
and other enhanced recovery projects and the availability of markets.

As of December 31, 1998, the Partnership possessed an interest in oil and
gas properties located in Eddy and Lea Counties of New Mexico; Andrews,
Borden, Cochran, Crane, Crockett, Dawson, Dimmitt, Gaines, Garza,
Glasscock, Hockley, Martin, Nolan, Pecos, Reagan, Reeves, Scurry, Sterling,
Stonewall, Terry, Winkler, Ward, Yoakum and Zavala Counties of Texas. The
Partnership owns royalty interests and net profit interests in the wells;
however, a substantial majority of the interests are net profit interests.
These properties consist of various interests in approximately 2,469 wells
and units.

Due to the Partnership's objective of maintaining current operations
without engaging in the drilling of any developmental or exploratory wells,
or additional acquisitions of producing properties, there has not been any
significant changes in properties during 1998, 1997 and 1996.

During 1998, twelve leases were sold for approximately $10,800. During
1997, three leases were sold for approximately $47,800. During 1996, there
were no property sales.

*Ryder Scott Company Petroleum Engineers prepared the reserve and present
value data for 96.4% of the Partnership's existing properties as of January
1, 1999. Another independent petroleum engineer prepared the remaining
3.6% of the Partnership's properties. The reserve estimates were made in
accordance with guidelines established by the Securities and Exchange
Commission pursuant to Rule 4-10(a) of Regulation S-X. Such guidelines
require oil and gas reserve reports be prepared under existing economic and
operating conditions with no provisions for price and cost escalation
except by contractual arrangements.

The New York Mercantile Exchange price at December 31, 1998 of $12.05 was
used as the beginning basis for the oil price. Oil price adjustments from
$12.05 per barrel were made in the individual evaluations to reflect oil
quality, gathering and transportation costs. The results are an average
price received at the lease of $10.11 per barrel in the preparation of the
reserve report as of January 1, 1999.

In the determination of the gas price, the New York Mercantile Exchange
price at December 31, 1998 of $1.95 was used as the beginning basis. Gas
price adjustments from $1.95 per Mcf were made in the individual
evaluations to reflect BTU content, gathering and transportation costs and
gas processing and shrinkage. The results are an average price received at
the lease of $1.86 per Mcf in the preparation of the reserve report as of
January 1, 1999.


As also discussed in Part II, Item 7, Management's Discussion and Analysis
of Financial Condition and Results of Operations, oil and gas prices were
subject to frequent changes in 1998.

The evaluation of oil and gas properties is not an exact science and
inevitably involves a significant degree of uncertainty, particularly with
respect to the quantity of oil or gas that any given property is capable of
producing. Estimates of oil and gas reserves are based on available
geological and engineering data, the extent and quality of which may vary
in each case and, in certain instances, may prove to be inaccurate.
Consequently, properties may be depleted more rapidly than the geological
and engineering data have indicated.

Unanticipated depletion, if it occurs, will result in lower reserves than
previously estimated; thus an ultimately lower return for the Partnership.
Basic changes in past reserve estimates occur annually. As new data is
gathered during the subsequent year, the engineer must revise his earlier
estimates. A year of new information, which is pertinent to the estimation
of future recoverable volumes, is available during the subsequent year
evaluation. In applying industry standards and procedures, the new data
may cause the previous estimates to be revised. This revision may increase
or decrease the earlier estimated volumes. Pertinent information gathered
during the year may include actual production and decline rates, production
from offset wells drilled to the same geologic formation, increased or
decreased water production, workovers, and changes in lifting costs, among
others. Accordingly, reserve estimates are often different from the
quantities of oil and gas that are ultimately recovered.

The Partnership has reserves which are classified as proved developed
producing, proved developed non-producing and proved undeveloped. All of
the proved reserves are included in the engineering reports which evaluate
the Partnership's present reserves.

Because the Partnership does not engage in drilling activities, the
development of proved undeveloped reserves is conducted pursuant to farm-
out arrangements with the Managing General Partner or unrelated third
parties. Generally, the Partnership retains a carried interest such as an
overriding royalty interest under the terms of a farm-out, or receives
cash.

The Partnership or the owners of properties in which the Partnership owns
an interest can engage in workover projects or supplementary recovery
projects, for example, to extract behind the pipe reserves which qualify as
proved developed non-producing reserves. See Part II, Item 7, Management's
Discussion and Analysis of Financial Condition and Results of Operations.

Item 3. Legal Proceedings

There are no material pending legal proceedings to which the Partnership is
a party.

Item 4. Submission of Matters to a Vote of Security Holders

No matter was submitted to a vote of security holders during the fourth
quarter of 1998 through the solicitation of proxies or otherwise.


Part II


Item 5. Market for the Registrant's Common Equity and Related Stockholder
Matters

Market Information
Limited partnership interests, or units, in the Partnership were initially
offered and sold for a price of $500. Limited partner units are not traded
on any exchange and there is no public or organized trading market for
them. The Managing General Partner has become aware of certain limited and
sporadic transfers of units between limited partners and third parties, but
has no verifiable information regarding the prices at which such units have
been transferred. Further, a transferee may not become a substitute
limited partner without the consent of the Managing General Partner.

After completion of the Partnership's first full fiscal year of operations
and each year thereafter, the Managing General Partner has offered and will
continue to offer to purchase each limited partner's interest in the
Partnership, at a price based on tangible assets of the Partnership, plus
the present value of the future net revenues of proved oil and gas
properties, minus liabilities with a risk factor discount of up to one-
third which may be implemented in the sole discretion of the Managing
General Partner. However, the Managing General Partner's obligation to
purchase limited partner units is limited to an expenditure of an amount
not in excess of 10% of the total limited partner units initially
subscribed for by limited partners. In 1998, 339.5 limited partner units
were tendered to and purchased by the Managing General Partner at an
average base price of $108.56 per unit. In 1997, 44 limited partner units
were tendered to and purchased by the Managing General Partner at an
average base price of $286.98 per unit. In 1996, 117 limited partner units
were tendered to and purchased by the Managing General Partner at an
average base price of $161.94 per unit.

Number of Limited Partner Interest Holders
As of December 31, 1998, there were 601 holders of limited partner units in
the Partnership.

Distributions
Pursuant to Article IV, Section 4.01 of the Partnership's Certificate and
Agreement of Limited Partnership "Net Cash Flow" is distributed to the
partners on a monthly basis. "Net Cash Flow" is defined as "the cash
generated by the Partnership's investments in producing oil and gas
properties, less (i) General and Administrative Costs, (ii) Operating
Costs, and (iii) any reserves necessary to meet current and anticipated
needs of the Partnership, as determined in the sole discretion of the
Managing General Partner."


During 1998, distributions were made totaling $240,472, with $218,472
distributed to the limited partners and $22,000 to the general partners.
For the year ended December 31, 1998, distributions of $21.53 per limited
partner unit were made, based upon 10,147 limited partner units
outstanding. The decline in distributions experienced in 1998 will be
expected to continue into 1999 based on the continued low oil price
economy. During 1997, twelve monthly distributions were made totaling
$581,000, with $522,900 distributed to the limited partners and $58,100 to
the general partners. For the year ended December 31, 1997, distributions
of $51.53 per limited partner unit were made, based upon 10,147 limited
partner units outstanding. During 1996, twelve monthly distributions were
made totaling $605,540, with $545,540 distributed to the limited partners
and $60,000 to the general partners. For the year ended December 31, 1996,
distributions of $53.76 per limited partner unit were made, based upon
10,147 limited partner units outstanding.

Item 6. Selected Financial Data

The following selected financial data for the years ended December 31,
1998, 1997, 1996, 1995 and 1994 should be read in conjunction with the

Item 7. Management's Discussion and Analysis of Financial Condition and
Results of Operations

General
The Partnership was formed to acquire nonoperating interests in producing
oil and gas properties, to produce and market crude oil and natural gas
produced from such properties and to distribute any net proceeds from
operations to the general and limited partners. Net revenues from
producing oil and gas properties are not reinvested in other revenue
producing assets except to the extent that producing facilities and wells
are reworked or where methods are employed to improve or enable more
efficient recovery of oil and gas reserves. The economic life of the
Partnership thus depends on the period over which the Partnership's oil and
gas reserves are economically recoverable.

Increases or decreases in Partnership revenues and, therefore,
distributions to partners will depend primarily on changes in the prices
received for production, changes in volumes of production sold, lease
operating expenses, enhanced recovery projects, offset drilling activities
pursuant to farm-out arrangements and on the depletion of wells. Since
wells deplete over time, production can generally be expected to decline
from year to year.

Well operating costs and general and administrative costs usually decrease
with production declines; however, these costs may not decrease
proportionately. Net income available for distribution to the limited
partners is therefore expected to fluctuate in later years based on these
factors.

Based on current conditions, management anticipates performing no workovers
during 1999 to enhance production. With expected price improvement,
workovers may be performed in the year 2002. The partnership may have an
increase in the year 2002, otherwise, the Partnership will most likely
experience it's historical decline of approximately 7% to 8% per year.


Results of Operations

A. General Comparison of the Years Ended December 31, 1998 and 1997

The following table provides certain information regarding performance
factors for the years ended December 31, 1998 and 1997:

Year Ended Percentage
December 31, Increase
1998 1997 (Decrease)
---- ---- ---------
Average price per barrel of oil $ 12.86 19.51 (34%)
Average price per mcf of gas $ 1.96 2.58 (24%)
Oil production in barrels 48,700 49,200 (1%)
Gas production in mcf 52,300 56,400 (7%)
Income from net profits interests $ 195,313 563,071 (65%)
Partnership distributions $ 240,472 581,000 (59%)
Limited partner distributions $ 218,472 522,900 (58%)
Per unit distribution to limited partners $ 21.53 51.53 (58%)
Number of limited partner units 10,147 10,147

Revenues

The Partnership's income from net profits interests decreased to $195,313
from $563,071 for the years ended December 31, 1998 and 1997, respectively,
a decrease of 65%. The principal factors affecting the comparison of the
years ended December 31, 1998 and 1997 are as follows:

1. The average price for a barrel of oil received by the Partnership
decreased during the year ended December 31, 1998 as compared to the
year ended December 31, 1997 by 34%, or $6.65 per barrel, resulting in
a decrease of approximately $327,200 in income from net profits
interests. Oil sales represented 86% of total oil and gas sales during
the year ended December 31, 1998 as compared to 87% during the year
ended December 31, 1997.

The average price for an mcf of gas received by the Partnership
decreased during the same period by 24%, or $.62 per mcf, resulting in
a decrease of approximately $35,000 in income from net profits
interests.

The total decrease in income from net profits interests due to the
change in prices received from oil and gas production is approximately
$362,200. The market price for oil and gas has been extremely volatile
over the past decade and management expects a certain amount of
volatility to continue in the foreseeable future.


2. Oil production decreased approximately 500 barrels or 1% during the
year ended December 31, 1998 as compared to the year ended December 31,
1997, resulting in a decrease of approximately $6,400 in income from
net profits interests.

Gas production decreased approximately 4,100 mcf or 7% during the same
period, resulting in a decrease of approximately $8,000 in income from
net profits interests.

The total decrease in income from net profits interests due to the
change in production is approximately $14,400.

3. Lease operating costs and production taxes were 2% lower, or
approximately $9,100 less during the year ended December 31, 1998 as
compared to the year ended December 31, 1997.

Costs and Expenses

Total costs and expenses increased to $596,467 from $255,828 for the years
ended December 31, 1998 and 1997, respectively, an increase of 133%. The
increase is the result of higher depletion expense, provision for
impairment and general and administrative expense.

1. General and administrative costs consists of independent accounting and
engineering fees, computer services, postage, and Managing General
Partner personnel costs. General and administrative costs increased
12% or approximately $10,000 during the year ended December 31, 1998 as
compared to the year ended December 31, 1997.

2. Depletion expense increased to $249,000 for the year ended December
31, 1998 from $175,000 for the same period in 1997. This represents an
increase of 42%. Depletion is calculated using the units of revenue method
of amortization based on a percentage of current period gross revenues to
total future gross oil and gas revenues, as estimated by the Partnership's
independent petroleum consultants.

A contributing factor to the increase in depletion expense between the
comparative periods was the decrease in the price of oil and gas used
to determine the Partnership's reserves for January 1, 1999 as compared
to 1998. Another contributing factor was due to the impact of
revisions of previous estimates on reserves. Revisions of previous
estimates can be attributed to the changes in production performance,
oil and gas price and production costs. The impact of the revision
would have increased depletion expense approximately $32,000 as of
December 31, 1997.

3. The Partnership reduced the net capitalized costs of oil and gas
properties by $256,624. This provision for impairment had the effect of
reducing net income, but did not affect cash flow or partner distributions.

Revenues

The Partnership's income from net profits interests decreased to $563,071
from $745,147 for the years ended December 31, 1997 and 1996, respectively,
a decrease of 24%. The principal factors affecting the comparison of the
years ended December 31, 1997 and 1996 are as follows:

1. The average price for a barrel of oil received by the Partnership
decreased during the year ended December 31, 1997 as compared to the
year ended December 31, 1996 by 8%, or $1.61 per barrel, resulting in a
decrease of approximately $92,100 in income from net profits interests.
Oil sales represented 87% of total oil and gas sales during the year
ended December 31, 1997 as compared to 88% during the year ended
December 31, 1996.

The average price for an mcf of gas received by the Partnership
decreased during the same period by 6%, or $.17 per mcf, resulting in a
decrease of approximately $10,000 in income from net profits interests.

The net total decrease in income from net profits interests due to the
change in prices received from oil and gas production is approximately
$102,100. The market price for oil and gas has been extremely volatile
over the past decade and management expects a certain amount of
volatility to continue in the foreseeable future.



2. Oil production decreased approximately 8,000 barrels or 14% during the
year ended December 31, 1997 as compared to the year ended December 31,
1996, resulting in a decrease of approximately $156,100 in income from
net profits interests.

Gas production decreased approximately 2,300 mcf or 4% during the same
period, resulting in a decrease of approximately $5,900 in income from
net profits interests.

The total decrease in income from net profits interests due to the
change in production is approximately $162,000. The decrease from 1996
to 1997 is in part due to normal decline and mechanical problems on two
wells.

3. Lease operating costs and production taxes were 13% lower, or
approximately $82,000 less during the year ended December 31, 1997 as
compared to the year ended December 31, 1996. Decrease from 1996 due
largely to significant cost in 1996 to re-equip a well.

Costs and Expenses

Total costs and expenses increased to $255,828 from $189,502 for the years
ended December 31, 1997 and 1996, respectively, an increase of 35%. The
increase is the result of higher depletion expense, partially offset by
general and administrative expense.

1. General and administrative costs consists of independent accounting and
engineering fees, computer services, postage, and Managing General
Partner personnel costs. General and administrative costs decreased 1%
or approximately $700 during the year ended December 31, 1997 as
compared to the year ended December 31, 1996.

4. Depletion expense increased to $175,000 for the year ended December
31, 1997 from $108,000 for the same period in 1996. This represents an
increase of 62%. Depletion is calculated using the units of revenue method
of amortization based on a percentage of current period gross revenues to
total future gross oil and gas revenues, as estimated by the Partnership's
independent petroleum consultants.

A contributing factor to the increase in depletion expense between the
comparative periods was the decrease in the price of oil and gas used
to determine the Partnership's reserves for January 1, 1998 as compared
to 1997. Another contributing factor was due to the impact of
revisions of previous estimates on reserves. Revisions of previous
estimates can be attributed to the changes in production performance,
oil and gas price and production costs. The impact of the revision
would have increased depletion expense approximately $60,000 as of
December 31, 1996.



C. Revenue and Distribution Comparison

Partnership net income (loss) for the years ended December 31, 1998, 1997
and 1996 was $(398,635), $319,497 and $558,108, respectively. Excluding
the effects of depreciation, depletion, amortization and provision for
impairment net income for the years ended December 31, 1998,1997 and 1996
would have been $106,989, $494,497 and $666,108, respectively.
Correspondingly, Partnership distributions for the years ended December 31,
1998, 1997 and 1996 were $240,472, $581,000 and $605,540, respectively.
These differences are indicative of the changes in oil and gas prices,
production and properties during 1998, 1997 and 1996.

The sources for the 1998 distributions of $240,472 were oil and gas
operations of approximately $208,000 and the change in oil and gas
properties of approximately $62,200, resulting in excess cash for
contingencies or subsequent distributions. The sources for the 1997
distributions of $581,000 were oil and gas operations of approximately
$554,100 and the change in oil and gas properties of approximately $1,000,
with the balance from available cash on hand at the beginning of the
period. The sources for the 1996 distributions of $605,540 were oil and
gas operations of approximately $595,800 and property sales of $1,000, with
the balance from available cash on hand at the beginning of the period.

Total distributions during the year ended December 31, 1998 were $240,472
of which $218,472 was distributed to the limited partners and $22,000 to
the general partners. The per unit distribution to limited partners during
the same period was $21.53. Total distributions during the year ended
December 31, 1997 were $581,000 of which $522,900 was distributed to the
limited partners and $58,100 to the general partners. The per unit
distribution to limited partners during the same period was $51.53. Total
distributions during the year ended December 31, 1996 were $605,540 of
which $545,540 was distributed to the limited partners and $60,000 to the
general partners. The per unit distribution to limited partners during the
same period was $53.76.

Since inception of the Partnership, cumulative monthly cash distributions
of $5,581,587 have been made to the partners. As of December 31, 1998,
$5,043,913 or $497.08 per limited partner unit, has been distributed to the
limited partners, representing a 99% return of the capital contributed.


Liquidity and Capital Resources

The primary source of cash is from operations, the receipt of income from
interests in oil and gas properties. The Partnership knows of no material
change, nor does it anticipate any such change.

Cash flows provided by operating activities were approximately $208,000 in
1998 compared to $554,100 in 1997 and approximately $595,800 in 1996. The
primary source of the 1998 cash flow from operating activities was
profitable operations.

Cash flows provided by investing activities were $62,200 in 1998 compared
to $1,030 in 1997 and approximately $1,000 in 1996. The principal source
of the 1998 cash flow from investing activities was the sale of oil and gas
properties.

Cash flows used in financing activities were approximately $240,100 in 1998
compared to $581,100 in 1997 and approximately $605,500 in 1996. The only
use in financing activities was the distributions to partners.

As of December 31, 1998, the Partnership had approximately $54,700 in
working capital. The Managing General Partner knows of no unusual
contractual commitments and believes the revenue generated from operations
are adequate to meet the needs of the Partnership.

Liquidity - Managing General Partner

The Managing General Partner has a highly leveraged capital structure with
over $21.0 million of interest payments due in 1999 on its debt
obligations. Due to severely depressed commodity prices, the Managing
General Partner is experiencing difficulty in generating sufficient cash
flow to meet its obligations and sustain its operations. The Managing
General Partner is currently in the process of renegotiating the terms of
its various obligations with its creditors and/or attempting to seek new
lenders or equity investors. Additionally, the Managing General Partner
would consider disposing of certain assets in order to meet its
obligations.

There can be no assurance that the Managing General Partner's debt
restructuring efforts will be successful or that the lenders will agree to
a course of action consistent with the Managing General Partners
requirements in restructuring the obligations. Even if such agreement is
reached, it may require approval of additional lenders, which is not
assured. Furthermore, there can be no assurance that the sales of assets
can be successfully accomplished on terms acceptable to the Managing
General Partner. Under current circumstances, the Managing General
Partner's ability to continue as a going concern depends upon its ability
to (1) successfully restructure its obligations or obtain additional
financing as may be required, (2) maintain compliance with all debt
covenants, (3) generate sufficient cash flow to meet its obligations on a
timely basis, and (4) achieve satisfactory levels of future earnings. If
the Managing General Partner is unsuccessful in its efforts, it may be
unable to meet its obligations making it necessary to undertake such other
actions as may be appropriate to preserve asset values.

Information Systems for the Year 2000

The Managing General Partner is continuing in its effort to identify and
assess its exposure to the potential Year 2000 software and imbedded chip
processing and date sensitivity issue. Through the Managing General
Partners data processing subsidiary, Midland Southwest Software, Inc., the
Managing General Partner proactively initiated a plan to identify
applicable hardware and software, assess impact and effect, estimate costs,
construct and implement corrective actions, and prepare contingency plans.


Identification & Assessment

The Managing General Partner currently believes it has identified the
internal and external software and hardware that may have date sensitivity
problems. Four critical systems and/or functions were identified: (1) the
proprietary software of the Partnership (OGAS) that is used for oil & gas
property management and financial accounting functions, (2) the DEC VAX/VMS
hardware and operating system, (3) various third-party application software
including lease economic analysis, fixed asset management, geological
applications, and payroll/human resource programs, and (4) External Agents.

The proprietary software of the Partnership is currently in process of
meeting compliance requirements with an estimated completion date of mid-
year 1999. Since this is an internally generated software package, the
Managing General Partner has estimated the cost to be approximately $25,000
by estimating the necessary man-hours. These modifications are being made
by internal staff and do not represent additional costs to the Partnership.
The Managing General Partner has not made contingency plans at this time
since the conversion is ahead of schedule and being handled by Managing
General Partner controlled internal programmers. Given the complexity of
the systems being modified, it is anticipated that some problems may arise,
but with an expected early completion date, the Managing General Partner
feels that adequate time is available to overcome unforeseen delays.

DEC has released a fully compliant version of its operating system that is
used by the Partnership on the DEC VAX system. It will be installed in
August 1999, the Managing General Partner believes that this will solve any
potential problems on the system.

The Managing General Partner has identified various third-party software
that may have date sensitivity problems and is working with the vendors to
secure solutions as well as prepare contingency plans. After review and
evaluation of the vendor plans and status, the Managing General Partner
believes that the problems will be resolved prior to the year 2000 or the
alternate contingency plan will sufficiently and adequately remediate the
problem so that there is no material disruption to business functions.


The External Agents of the Partnership include suppliers, customers,
owners, vendors, banks, product purchasers including pipelines, and other
oil and gas property operators. The Managing General Partner is in the
process of identifying and communicating with each critical External Agent
about its plan and progress thereof in addressing the Year 2000 issue.
This process is on schedule and the Managing General Partner, at this time,
believes that there should be no material interference or disruption
associated with any of the critical External Agent's functions necessary to
the Partnership's business. The Managing General Partner estimates
completion of this audit by mid-year 1999 and believes that alternate plans
can be devised to circumvent any material problems arising from critical
External Agent noncompliance.

Cost

To date, the Managing General Partner has incurred only minimal internal
man-hour costs for identification, planning, and maintenance. The Managing
General Partner believes that the necessary additional costs will also be
minimal and most will fall under normal and general maintenance procedures
and updates. An accurate cost cannot be determined at this time, but it is
expected that the total cost to remediate all systems to be less than
$50,000.


Risks/Contingency

The failure to correct critical systems of the Partnership, or the failure
of a material business partner or External Agent to resolve critical Year
2000 issues could have a serious adverse impact on the ability of the
Partnership to continue operations and meet obligations. Based on the
Managing General Partner's evaluation and assessment to date, it is
believed that any interruption in operation will be minor and short-lived
and pose no material monetary loss, safety, or environmental risk to the
Partnership. However, until all assessment is complete, it is impossible
to accurately identify the risks, quantify potential impacts or establish a
final contingency plan. The Managing General Partner believes that its
assessment and contingency planning will be complete no later than mid-year
1999.

Worst Case Scenario

The Securities and Exchange Commission requires that public companies must
forecast the most reasonably likely worst case Year 2000 scenario, assuming
that the Managing General Partner's Year 2000 plan is not effective.
Analysis of the most reasonably likely worst case Year 2000 scenarios the
Partnership may face leads to contemplation of the following possibilities
which, though considered highly unlikely, must be included in any
consideration of worst cases: widespread failure of electrical, gas, and
similar supplies by utilities serving the Partnership; widespread
disruption of the services of communications common carriers; similar
disruption to means and modes of transportation for the Partnership and its
employees, contractors, suppliers, and customers; significant disruption to
the Partnership's ability to gain access to, and continue working in,
office buildings and other facilities; and the failure, of third-parties
systems, the effects of which would have a cumulative material adverse
impact on the Partnership's critical systems. The Partnership could
experience an inability by customers, traders, and others to pay, on a
timely basis or at all, obligations owed to the Partnership. Under these
circumstances, the adverse effect on the Partnership, and the diminution of
Partnership revenues, could be material, although not quantifiable at this
time.

Notes to Financial Statements


1. Organization
Southwest Royalties Institutional Income Fund VIII-B, L.P. was
organized under the laws of the state of Delaware on November 30,
1987, for the purpose of acquiring producing oil and gas properties
and to produce and market crude oil and natural gas produced from such
properties for a term of 50 years, unless terminated at an earlier
date as provided for in the Partnership Agreement. The offering of
limited partner units began March 31, 1988, minimum capital
requirements were met July 11, 1988, with the offering concluded on
March 31, 1989.

The Partnership sells its oil and gas production to a variety of
purchasers with the prices it receives being dependent upon the oil
and gas economy. Southwest Royalties, Inc. serves as the Managing
General Partner and H. H. Wommack, III, as the individual general
partner. Revenues, costs and expenses are allocated as follows:

Limited General
Partners Partners
-------- --------
Interest income on capital contributions 100% -
Oil and gas sales from net profits interests 90% 10%
All other revenues 90% 10%
Organization and offering costs (1) 100% -
Amortization of organization costs 100% -
Property acquisition costs 100% -
Gain/loss on property dispositions 90% 10%
Operating and administrative costs (2) 90% 10%
Depreciation, depletion and amortization
of oil and gas properties 100% -
All other costs 90% 10%

(1) All organization costs in excess of 3% of initial capital
contributions will be paid by the Managing General Partner and
will be treated as a capital contribution. The Partnership paid
the Managing General Partner an amount equal to 3% of initial
capital contributions for such organization costs.

(2) Administrative costs in any year which exceed 2% of capital
contributions shall be paid by the Managing Partner and will be
treated as a capital contribution.

Notes to Financial Statements


2. Summary of Significant Accounting Policies

Oil and Gas Properties
Oil and gas properties are accounted for at cost under the full-cost
method. Under this method, all productive and nonproductive costs
incurred in connection with the acquisition, exploration and
development of oil and gas reserves are capitalized. Gain or loss on
the sale of oil and gas properties is not recognized unless
significant oil and gas reserves are involved.

The Partnership's policy for depreciation, depletion and amortization
of oil and gas properties is computed under the units of revenue
method. Under the units of revenue method, depreciation, depletion
and amortization is computed on the basis of current gross revenues
from production in relation to future gross revenues, based on current
prices, from estimated production of proved oil and gas reserves.

Under the units of revenue method, the Partnership computes the
provision by multiplying the total unamortized cost of oil and gas
properties by an overall rate determined by dividing (a) oil and gas
revenues during the period by (b) the total future gross oil and gas
revenues as estimated by the Partnership's independent petroleum
consultants. It is reasonably possible that those estimates of
anticipated future gross revenues, the remaining estimated economic
life of the product, or both could be changed significantly in the
near term due to the potential fluctuation of oil and gas prices or
production. The depletion estimate would also be affected by this
change.

Should the net capitalized costs exceed the estimated present value of
oil and gas reserves, discounted at 10%, such excess costs would be
charged to current expense. As of December 31, 1998, net capitalized
cost exceeded the estimated present value of oil and gas reserves,
thus an adjustment of $256,624 was made to the financial statement.
As of December 31, 1997 and 1996 the net capitalized costs did not
exceed the estimated present value of oil and gas reserves.

The Partnership's interest in oil and gas properties consists of net
profits interests in proved properties located within the continental
United States. A net profits interest is created when the owner of a
working interest in a property enters into an arrangement providing
that the net profits interest owner will receive a stated percentage
of the net profit from the property. The net profits interest owner
will not otherwise participate in additional costs and expenses of the
property.

2. Summary of Significant Accounting Policies - continued

Estimates and Uncertainties
The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the
date of the financial statements and the reported amounts of revenues
and expenses during the reporting period. Actual results could differ
from those estimates.

Syndication Costs
Syndication costs are accounted for as a reduction of partnership
equity.

Environmental Costs
The Partnership is subject to extensive federal, state and local
environmental laws and regulations. These laws, which are constantly
changing, regulate the discharge of materials into the environment and
may require the Partnership to remove or mitigate the environmental
effects of the disposal or release of petroleum or chemical substances
at various sites. Environmental expenditures are expensed or
capitalized depending on their future economic benefit.

Costs which improve a property as compared with the condition of the
property when originally constructed or acquired and costs which
prevent future environmental contamination are capitalized.
Expenditures that relate to an existing condition caused by past
operations and that have no future economic benefits are expensed.
Liabilities for expenditures of a non-capital nature are recorded when
environmental assessment and/or remediation is probable, and the costs
can be reasonably estimated.

Gas Balancing
The Partnership utilizes the sales method of accounting for gas-
balancing arrangements. Under this method the Partnership recognizes
sales revenue on all gas sold. As of December 31, 1998, 1997 and
1996, there were no significant amounts of imbalance in terms of units
and value.

2. Summary of Significant Accounting Policies - continued

Cash and Cash Equivalents
For purposes of the statement of cash flows, the Partnership considers
all highly liquid debt instruments purchased with a maturity of three
months or less to be cash equivalents. The Partnership maintains its
cash at one financial institution.

Income Taxes
No provision for income taxes is reflected in these financial
statements, since the tax effects of the Partnership's income or loss
are passed through to the individual partners.

In accordance with the requirements of Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes", the
Partnership's tax basis in its oil and gas properties at December 31,
1998 and 1997 is $512,811 and $212,510, more respectively, than that
shown on the accompanying Balance Sheets in accordance with generally
accepted accounting principles.

Number of Limited Partner Units
As of December 31, 1998, 1997 and 1996, there were 10,147 limited
partner units outstanding held by 601, 615 and 631 partners.

Concentrations of Credit Risk
The Partnership is subject to credit risk through trade receivables.
Although a substantial portion of its debtors' ability to pay is
dependent upon the oil and gas industry, credit risk is minimized due
to a large customer base. All partnership revenues are received by
the Managing General Partner and subsequently remitted to the
partnership and all expenses are paid by the Managing General Partner
and subsequently reimbursed by the partnership.

Fair Value of Financial Instruments
The carrying amount of cash and accounts receivable approximates fair
value due to the short maturity of these instruments.

Net Income (loss) per limited partnership unit
The net income (loss) per limited partnership unit is calculated by
using the number of outstanding limited partnership units.

3. Liquidity - Managing General Partner
The Managing General Partner has a highly leveraged capital structure
with over $21.0 million of interest payments due in 1999 on its debt
obligations. Due to severely depressed commodity prices, the Managing
General Partner is experiencing difficulty in generating sufficient
cash flow to meet its obligations and sustain its operations. The
Managing General Partner is currently in the process of renegotiating
the terms of its various obligations with its creditors and/or
attempting to seek new lenders or equity investors. Additionally, the
Managing General Partner would consider disposing of certain assets in
order to meet its obligations.

There can be no assurance that the Managing General Partner's debt
restructuring efforts will be successful or that the lenders will
agree to a course of action consistent with the Managing General
Partners requirements in restructuring the obligations. Even if such
agreement is reached, it may require approval of additional lenders,
which is not assured. Furthermore, there can be no assurance that the
sales of assets can be successfully accomplished on terms acceptable
to the Managing General Partner. Under current circumstances, the
Managing General Partner's ability to continue as a going concern
depends upon its ability to (1) successfully restructure its
obligations or obtain additional financing as may be required, (2)
maintain compliance with all debt covenants, (3) generate sufficient
cash flow to meet its obligations on a timely basis, and (4) achieve
satisfactory levels of future earnings. If the Managing General
Partner is unsuccessful in its efforts, it may be unable to meet its
obligations making it necessary to undertake such other actions as may
be appropriate to preserve asset values.

4. Commitments and Contingent Liabilities
After completion of the Partnership's first full fiscal year of
operations and each year thereafter, the Managing General Partner has
offered and will continue to offer to purchase each limited partner's
interest in the Partnership, at a price based on tangible assets of
the Partnership, plus the present value of the future net revenues of
proved oil and gas properties, minus liabilities with a risk factor
discount of up to one-third which may be implemented in the sole
discretion of the Managing General Partner. However, the Managing
General Partner's obligation to purchase limited partner units is
limited to an expenditure of an amount not in excess of 10% of the
total limited partner units initially subscribed for by limited
partners.

The Partnership is subject to various federal, state and local
environmental laws and regulations which establish standards and
requirements for protection of the environment. The Partnership
cannot predict the future impact of such standards and requirements,
which are subject to change and can have retroactive effectiveness.
The Partnership continues to monitor the status of these laws and
regulations.

As of December 31, 1998, the Partnership has not been fined, cited or
notified of any environmental violations and management is not aware
of any unasserted violations which would have a material adverse
effect upon capital expenditures, earnings or the competitive position
in the oil and gas industry.

However, the Managing General Partner does recognize by the very
nature of its business, material costs could be incurred in the near
term to bring the Partnership into total compliance. The amount of
such future expenditures is not reliably determinable due to several
factors, including the unknown magnitude of possible contaminations,
the unknown timing and extent of the corrective actions which may be
required, the determination of the Partnership's liability in
proportion to other responsible parties and the extent to which such
expenditures are recoverable from insurance or indemnifications from
prior owners of Partnership's properties.

5. Related Party Transactions
A significant portion of the oil and gas properties in which the
Partnership has an interest are operated by and purchased from the
Managing General Partner. As is usual in the industry and as provided
for in the operating agreement for each respective oil and gas
property in which the Partnership has an interest, the operator is
paid an amount for administrative overhead attributable to operating
such properties, with such amounts to Southwest Royalties, Inc. as
operator approximating $102,200, $97,000 and $94,000 for the years
ended December 31, 1998, 1997 and 1996, respectively. In addition,
the Managing General Partner and certain officers and employees may
have an interest in some of the properties that the Partnership also
participates.

Certain subsidiaries or affiliates of the Managing General Partner
perform various oilfield services for properties in which the
Partnership owns an interest. Such services aggregated approximately
$2,600, $2,600 and $14,000 for the years ended December 31, 1998,
1997, and 1996, respectively, and the Managing General Partner
believes that these costs are comparable to similar charges paid by
the Partnership to unrelated third parties.

Southwest Royalties, Inc., the Managing General Partner, was paid
$72,000 during 1998, 1997 and 1996, as an administrative fee for
reimbursement of indirect general and administrative overhead
expenses.

Receivables from Southwest Royalties, Inc., the Managing General
Partner, of approximately $21,620 and $122,680 are from oil and gas
production, net of lease operating costs and production taxes, as of
December 31, 1998 and 1997, respectively.

In addition, a director and officer of the Managing General Partner is
a partner in a law firm, with such firm providing legal services to
the Partnership. There were no legal services provided for the year
ended December 31, 1998, 1997 and approximately $70 for the year ended
December 31, 1996.

6. Major Customers
No material portion of the Partnership's business is dependent on a
single purchaser, or a very few purchasers, where the loss of one
would have a material adverse impact on the Partnership. Two
purchasers accounted for 74% of the Partnership's total oil and gas
production during 1998: Scurlock Permian LLC for 50% and Mobil
Corporation for 24%. Two purchasers accounted for 73% of the
Partnership's total oil and gas production during 1997: Scurlock
Permian Corporation 50%, and Mobil Corporation 23%. Two purchasers
accounted for 77% of the Partnership's total oil and gas production
during 1996: Scurlock Permian Corporation 52% and Mobil Corporation
25%. All purchasers of the Partnership's oil and gas production are
unrelated third parties. In the event any of these purchasers were to
discontinue purchasing the Partnership's production, the Managing
General Partner believes that a substitute purchaser or purchasers
could be located without undue delay. No other purchaser accounted
for an amount equal to or greater than 10% of the Partnership's sales
of oil and gas production.

December 31, 1997 331,000 349,000
======= =======
December 31, 1998 193,000 147,000
======= =======

All of the Partnership's reserves are located within the continental
United States.

*Ryder Scott Company Petroleum Engineers prepared the reserve and
present value data for 96.4% of the Partnership's existing properties
as of January 1, 1999. Another independent petroleum engineer
prepared the remaining 3.6% of the Partnership's properties. The
reserve estimates were made in accordance with guidelines established
by the Securities and Exchange Commission pursuant to Rule 4-10(a) of
Regulation S-X. Such guidelines require oil and gas reserve reports
be prepared under existing economic and operating conditions with no
provisions for price and cost escalation except by contractual
arrangements.

The New York Mercantile Exchange price at December 31, 1998 of $12.05
was used as the beginning basis for the oil price. Oil price
adjustments from $12.05 per barrel were made in the individual
evaluations to reflect oil quality, gathering and transportation
costs. The results are an average price received at the lease of
$10.11 per barrel in the preparation of the reserve report as of
January 1, 1999.

Notes to Financial Statements


7. Estimated Oil & Gas Reserves (unaudited) - continued
In the determination of the gas price, the New York Mercantile
Exchange price at December 31, 1998 of $1.95 was used as the beginning
basis. Gas price adjustments from $1.95 per Mcf were made in the
individual evaluations to reflect BTU content, gathering and
transportation costs and gas processing and shrinkage. The results
are an average price received at the lease of $1.86 per Mcf in the
preparation of the reserve report as of January 1, 1999.

The evaluation of oil and gas properties is not an exact science and
inevitably involves a significant degree of uncertainty, particularly
with respect to the quantity of oil or gas that any given property is
capable of producing. Estimates of oil and gas reserves are based on
available geological and engineering data, the extent and quality of
which may vary in each case and, in certain instances, may prove to be
inaccurate. Consequently, properties may be depleted more rapidly
than the geological and engineering data have indicated.

Unanticipated depletion, if it occurs, will result in lower reserves
than previously estimated; thus an ultimately lower return for the
Partnership. Basic changes in past reserve estimates occur annually.
As new data is gathered during the subsequent year, the engineer must
revise his earlier estimates. A year of new information, which is
pertinent to the estimation of future recoverable volumes, is
available during the subsequent year evaluation. In applying industry
standards and procedures, the new data may cause the previous
estimates to be revised. This revision may increase or decrease the
earlier estimated volumes. Pertinent information gathered during the
year may include actual production and decline rates, production from
offset wells drilled to the same geologic formation, increased or
decreased water production, workovers, and changes in lifting costs,
among others. Accordingly, reserve estimates are often different from
the quantities of oil and gas that are ultimately recovered.

The Partnership has reserves which are classified as proved developed
producing, proved developed non-producing and proved undeveloped. All
of the proved reserves are included in the engineering reports which
evaluate the Partnership's present reserves.

Because the Partnership does not engage in drilling activities, the
development of proved undeveloped reserves is conducted pursuant to
farm-out arrangements with the Managing General Partner or unrelated
third parties. Generally, the Partnership retains a carried interest
such as an overriding royalty interest under the terms of a farm-out,
or receives cash.

Item 9. Changes in and Disagreements With Accountants on Accounting and
Financial Disclosure

On June 9, 1997 Southwest Royalties, Inc. the Partnership's Managing
General Partner (Southwest Royalties, Inc.) dismissed Joseph Decosimo and
Company as the Partnership's independent accountants. The Managing General
Partner's Board of Directors approved the decision to change the
Partnership's independent accountants.

The report of Joseph Decosimo and Company on the financial statements for
the fiscal year ended December 31, 1996 contained no adverse opinion or
disclaimer of opinion and was not qualified or modified as to uncertainty,
audit scope or accounting principle.

In connection with its audit for the fiscal year ended December 31, 1996
and through June 9, 1997, there have been no disagreements with Joseph
Decosimo and Company on any matter of accounting principles or practices,
financial statements disclosure, or auditing scope or procedure, which
disagreements if not resolved to the satisfaction of Joseph Decosimo and
Company would have caused them to make reference thereto in their report on
the financial statements for such year.

The Registrant has requested that Joseph Decosimo and Company furnish it
with a letter addressed to the SEC stating whether or not is agrees with
the above statements. A copy of that letter is included as Exhibit 16 and
has been filed with the Securities and Exchange Commission.

In certain instances, the Managing General Partner will engage professional
petroleum consultants and other independent contractors, including
engineers and geologists in connection with property acquisitions,
geological and geophysical analysis, and reservoir engineering. The
Managing General Partner believes that, in addition to its own "in-house"

partner. Through repurchase offers to the limited partners, the Managing
General Partner also owns 922.5 limited partner units, a 9.1% limited
partner interest. The Managing General Partner total percentage interest
ownership in the Partnership is 16.5%.

No officer or director of the Managing General Partner owns Units in the

Item 13. Certain Relationships and Related Transactions

In 1998, the Managing General Partner received $72,000 as an administrative
fee. This amount is part of the general and administrative expenses
incurred by the Partnership.

In some instances the Managing General Partner and certain officers and
employees may be working interest owners in an oil and gas property in
which the Partnership also has a net profits interest. Certain properties
in which the Partnership has an interest are operated by the Managing
General Partner, who was paid approximately $102,200 for administrative
overhead attributable to operating such properties during 1998.

Certain subsidiaries or affiliates of the Managing General Partner perform
various oilfield services for properties in which the Partnership owns an
interest. Such services aggregated approximately $2,600 for the year ended
December 31, 1998.

In the opinion of management, the terms of the above transactions are
similar to ones with unaffiliated third parties.
