         This 10-KSB report contains forward looking statements that involve
risks and uncertainties.  The Company's actual results could differ materially
from those discussed herein.  Factors that could cause or contribute to such
differences include, but are not limited to, the factors set forth in the
section entitled "Description of Business-Risk Factors", those discussed in
"Management's Discussion and Analysis of Financial Condition and Results of
Operations" and those discussed elsewhere in this report.

Item 1.  Description of Business

         Adair International Oil and Gas, Inc. (the "Company") was originally
incorporated in the state of Texas on November 7, 1980, as Roberts Oil and Gas,
Inc.  The name of the Company was changed to its present title pursuant to an
amendment to its articles of incorporation effective July 25, 1997.  The
Company generally engages in the holding of interests in oil and gas
properties.  Until 1997 the Company's activities were limited to the United
States.

         The Company began to acquire interests in oil and gas properties in
1981 and, following a registration of its shares of common stock with the
Securities and Exchange Commission (the "SEC"), to file reports under the
Securities Exchange Act of 1934 (the "Exchange Act").  However, by the
mid-1980's the oil and gas market was in a downturn, the Company was
experiencing financial difficulties and it did not have sufficient resources to
continue the exploration and development of oil and gas properties.  While the
Company continued to hold interests in wells, it had become essentially
dormant.  One of the consequences of that situation was that, beginning in
1989, the Company filed its annual report on Form 10-K under the Exchange Act
without including audited financial statements as required by the Exchange Act.
In addition, the Company may not have fully complied with other formalities
required under the Exchange Act and the filings due thereunder.

         During 1997 the Company has made numerous changes in its operations
and the focus of its business.  The Company's business expanded to, and became
highly dependent upon, foreign operations when it acquired interests in
contracts pertaining to oil and/or gas properties in Colombia, Yemen and
Paraguay.  In connection with the transactions relating to those acquisitions,
the controlling interest in the Company's common stock was issued to persons
not previously affiliated with the Company.  In June, following the resignation
of members of the board then in office, three new members of the board were
elected.  The new board then selected a new chief executive officer and a new
chief financial officer.

         The oil and gas wells which the Company holds in the United States
have experienced normal declines in production during past
<PAGE>   4
years and the Company does not expect that it will be able to generate any
substantial increases in revenue from those interests in the future than is
currently being derived.  The Company's future prospects will be dependent upon
its ability to benefit from the interests which it holds in properties and
contracts in foreign countries.  However, as described hereafter, it will be
necessary to find a source of funds or form joint venture partners in order for
the Company to develop its interests in the foreign properties.

         Management of the Company has been concentrating efforts on financing
the exploration and development of its foreign properties.

Transactions pertaining to properties in Colombia.

         On February 27, 1997, the Company entered into an agreement with
Geopozos, S.A. ("Geopozos") pursuant to which it agreed to issue shares of its
common stock to Geopozos (the "Geopozos Agreement"), subject to approval of the
agreement by the Company's board of directors, in connection with the
acquisition of specified assets.   As part of the Geopozos Agreement the
Company agreed to issue to Geopozos two million (2,000,000) shares of its
common stock and a promissory note in the principal amount of six hundred
thousand dollars ($600,000).  The promissory note does not bear any interest
and does not have a maturity date but instead provides that it is due and
payable from the first proceeds of any funds raised in order to fund the
exploration of the relevant properties.  However, if Ecopetrol, the national
oil company of Colombia, grants commercialization of a specified property the
Company may be due a like amount from recovered expenses.

         In connection with the acquisition of those assets, on March 14, 1997,
the Company also entered into an agreement with ROGI International, a company
incorporated under the laws of Panama, (the "ROGI International Agreement")
pursuant to which the Company agreed to issue, as required by the Geopozos
Agreement, the two million (2,000,000) shares of its common stock to persons or
entities as directed by Geopozos and four million (4,000,000) shares of its
common stock to persons or entities as directed by ROGI International in
exchange for the assets being acquired.  Thus, a total of six million
(6,000,000) shares were issued in exchange for the assets.  The Geopozos
Agreement also provides that Geopozos may, at its election, nominate a person
to serve on the board of directors of the Company.  Geopozos has not nominated
any person to serve on the Company's board.

         The shares issued pursuant to the Geopozos and ROGI International
Agreements were authorized but unissued shares of the Company.  On behalf of
Geopozos the two million (2,000,000) shares were issued to two corporations and
ROGI International directed that the four million (4,000,000) shares be issued
to seven corporations and one individual.  The Company has not been
<PAGE>   5
informed of the relationship or affiliation, if any, among those entities.
Assuming that none of the entities acquiring shares are affiliated, following
the completion of the transaction with Adair Oil International Canada, Inc., as
hereafter described, the only entity which acquired as a holder of record five
percent (5%) or more of the then- outstanding shares of the Company's common
stock in connection with the aforesaid transaction was Petroleum Exploration
Services, Inc. which acquired one million six hundred thousand (1,600,000)
shares of common stock, representing 7.5% of the Company's outstanding common
stock as of July 31, 1997.

         The assets which were transferred to the Company in exchange for the
promissory note and the issuance of shares consist of a one hundred percent
(100%) interest in the Chimichagua Association Contract in Colombia.  For a
description of the assets acquired, see "Item 2. Description of Property"
herein.

Transaction with Adair Oil International Canada, Inc.

         On June 16, 1997, the Company closed on an agreement with Adair Oil
International Canada, Inc. ("Adair Oil"), a Bahamas corporation, pursuant to
which the Company transferred to Adair Oil a fifty-one percent (51%)
controlling interest in the outstanding common stock of the Company.  As a
result of that agreement 10,200,000 shares of the Company's common stock were
issued to Adair Oil in exchange for a portion of Adair Oil's rights with
respect to certain contracts.  The shares issued to Adair Oil consisted of
10,000,000 shares of the Company's authorized but unissued shares and, in order
to complete the transaction with Adair Oil, 200,000 shares which were loaned
and returned to the Company by two of the entities which received shares as
part of the ROGI International Agreement.

         In connection with the Adair Oil transaction all of the former
directors of the Company, except Earl Roberts, agreed to resign and Earl
Roberts agreed to elect persons designated by Adair Oil to the Company's board
of directors.  Immediately following the closing of the Adair Oil transaction
and the resignation of members of the Company's board of directors, Earl
Roberts caused John Adair, Jalal Alghani and Abdul Aziz M. Al-Abdulkader, the
designees of Adair Oil, to be elected to the Company's board of directors.

         As part of the Company's agreement with Adair Oil certain stockholders
of the Company also entered into a voting agreement, effective until December
31, 1997, with each other with respect to certain matters which might be voted
upon by the shareholders of the Company.  Certain shareholders also each
individually granted to John Adair, the president of Adair Oil, irrevocable
proxies until December 31, 1997, to vote on their behalf shares of the
Company's common stock owned by the grantors of the proxies with respect to
those same matters.  The matters covered by the voting agreement and the
proxies include the increase in
<PAGE>   6
the number of shares which the Company is authorized to issue and the
determination of the rights and privileges of each class of the Company's
stock.  The shareholders entering into the voting trust agreement included
Adair Oil and those entities which acquired shares pursuant to the Geopozos and
ROGI International Agreements.  Thus, at the time the voting agreement was
entered into the parties to the voting agreement controlled fourteen million
(14,000,000) shares of the Company's outstanding common stock.  The entities
which executed the proxies held four million (4,000,000) shares of the
Company's common stock.

         In exchange for the issuance of shares of its stock to Adair Oil, the
Company acquired five percent (5%) of the net profits in Adair Oil's interest
in each of the contracts pertaining to properties in Yemen and Paraguay.  The
Company did not acquire the right or obligation to participate in the
management or operation of any of the properties.  For a description of the
assets acquired, see "Item 2.  Description of Property" herein.

The Interests in Yemen.

         The Yemen contracts (the "Yemen Contracts") were initially acquired in
1993 by Adair Oil International, Inc.  ("AOI"), a Bahamas corporation, from the
Republic of Yemen and relate to two different areas, one of which is off the
coast of Yemen.  AOI assigned its rights to the Yemen Contracts to Adair Oil on
June 16, 1997.  The Yemen Contracts grant to AOI the rights and obligations to
explore for oil, gas and/or related extractable resources and to develop the
areas covered by the contracts if AOI deems the areas to be worthy of
commercial development.  The contracts reserve a royalty interest of ten
percent (10%) to the Republic of Yemen, after which AOI and its assignees have
the right, after payment of specified production costs, to share in the
revenues with the Ministry of Oil and Mineral Resources of Yemen.  This revenue
sharing arrangement provides that AOI shall receive revenues ranging from ten
percent (10%) to thirty percent (30%), depending upon the amount of production.

         Under the Yemen Contracts AOI was required to expend at least eighteen
million dollars ($18,000,000) on the exploration of one of the areas within
thirty (30) months, and fifteen million dollars ($15,000,000) on the
exploration of the other area within thirty-six (36) months, after the
effective date of the contracts.  The effective date of each of the contracts
was June 20, 1993.  The terms of the contracts also imposed certain financial
conditions on AOI.  AOI has indicated that it is of the opinion that it
provided evidence of financial capability with respect to its exploration
obligations in accordance with the terms of the contracts.

         The Yemen Contracts also imposed certain obligations on AOI with
respect to the exploration of the properties.  Under those obligations AOI was
required to acquire and process seismic data and mobilize, drill and evaluate
two exploration wells during the
<PAGE>   7
relevant exploration time.  AOI did not perform each of the obligations with
respect to the exploration of the areas.  However, under the terms of the
contracts, if AOI is prevented from doing so because of "force majeure", the
time for compliance with that portion of each of the contracts is extended for
such period of time as the force majeure continues.  One of the conditions
defined as being force majeure is the order, regulation or direction of the
government of Yemen which prevents AOI from performing its obligations under
the contract.  During a portion of the time since AOI executed the Yemen
Contracts Yemen was in civil war and the government in political upheaval.  AOI
believes that those factors prevented AOI from performing under the Yemen
Contracts and that such prevention constitutes force majeure as that term is
defined in the Yemen Contracts.  AOI therefore believes that, it continues to
have rights with respect to the Yemen Contracts.  AOI's representative in Yemen
has discussed these issues with the Minister of Oil of Yemen and has indicated
to AOI that he believes that AOI continues to have the rights specified under
the contracts.  The representative has also indicated that he believes that AOI
has the right to renegotiate the terms of its Yemen Contracts and that it may
be possible to obtain terms which are more favorable to the holder of the
rights.  Adair Oil has indicated that it intends to pursue such negotiation.

The Interests in Paraguay.

         Adair Oil International Co. Canada, Inc., a Canadian corporation
("Adair-Canada") acquired, subject to the fulfillment of certain obligations,
on May 30, 1997, from Guarani Petroleum Exploration, S.A. ("Guapex"), a
Paraguay corporation, as representative of a consortium of entities, including
Guapex, a portion of a concession contract relating to 3,292,900 hectares
located in Paraguay (the "Alto Parana Contract").   A portion of the interests
in second concession contract respecting 2,400,000 hectares located in Paraguay
(the "San Pedro Contract") was obtained, subject to the fulfillment of certain
obligations, by Adair-Canada from Guapex on May 31, 1997.  Adair-Canada
assigned all of its interests in the San Pedro Contract and the Alto Parana
Contract to Adair Oil on June 16, 1997, and Adair Oil succeeded to the rights
and obligations of Adair-Canada.  Thus, in describing the aforesaid contracts,
Adair Oil is used hereafter to describe the rights and obligations initially
held by Adair-Canada.

         Adair Oil acquired ninety nine percent (99%) of Guapex's interest in
the concession (the "San Pedro Concession") which is the subject of the San
Pedro Contract, with Guapex retaining the remaining one percent (1%).  The
expenses and revenues of the wells, after payment by Adair Oil of certain
expense obligations as hereafter described, are shared pro rata by Adair Oil
and Guapex in those same ratios.  Guapex also retained a ten percent (10%)
overriding royalty interest in the hydrocarbons which are recovered from any
wells drilled on the San Pedro Concession.
<PAGE>   8
Under the terms of the San Pedro Contract, the interests being acquired by
Adair Oil are being held in escrow until Adair Oil has met certain conditions,
referred to as "Earning Obligations."  After complying with those Earning
Obligations Adair Oil will be entitled to receive the assignment of 99% of
Guapex's interests in the San Pedro Concession contract.

         The Earning Obligations of Adair Oil with respect to the San Pedro
Contract require that (i) Adair Oil pay an aggregate of three million dollars
($3,000,000) to Guapex for the San Pedro Concession and the Alto Parana
Concession on or before July 31, 1997, (ii) Adair Oil drill and complete, at
Adair Oil's expense, two wells on the San Pedro Concession no later than
December 1, 1998, and (iii) Adair Oil pay all of the costs, up to a maximum of
$2,272,000, of the seismic work required with respect to the exploration of the
San Pedro Concession.  The seismic work must begin before October 1, 1997.
Adair Oil did not pay the three million dollars ($3,000,000) prior to July 31,
1997.  However, Adair Oil has been given an extension of time by Guapex to meet
that obligation.

         Adair Oil and Guapex have agreed to enter into a Joint Operating
Agreement with respect to the development of the San Pedro Concession.  The
terms of such operating agreement are to be determined through negotiations
between the parties.

         The Alto Parana Concession was initially acquired from the government
of Paraguay in 1989 by Texaco Exploration Paraguay and subsequently assigned to
Guapex, which assignment was approved by the government of Paraguay.  Adair Oil
is acquiring sixty percent (60%) of Guapex's interest in the Alto Parana
Concession.  The assignment to Adair Oil has been made by Guapex and been
placed in escrow.  Adair Oil has the right to receive the interest assigned
upon timely completion of the Earning Obligations imposed on Adair Oil in the
Alto Parana Contract.

         The Earning Obligations of Adair Oil with respect to the Alto Parana
Contract require that (i) Adair Oil pay an aggregate of three million dollars
($3,000,000) to Guapex for the San Pedro Concession and the Alto Parana
Concession, with one million dollars ($1,000,000) attributable to the Alto
Parana Concession to be paid on or before May 31, 1997, (ii) Adair Oil drill
and complete, at Adair Oil's expense, two wells on the Alto Parana Concession
no later than January 1, 1999, with the first well to be completed no later
than March 31, 1997, and (iii) Adair Oil pay all of the costs, up to a maximum
of $2,272,000, of the seismic work required with respect to the exploration of
the Alto Parana Concession.  The seismic work was to begin before July 31,
1997.  Adair Oil did not pay the one million dollars ($1,000,000) prior to May
31, 1997, nor has it begun the seismic work.  However, Adair Oil has been given
an extension of time by Guapex to meet those obligations.  Adair Oil also
believes that the contract provision which required the drilling of a well by
March 31, 1997, was one of mutual mistake and will not be considered by
<PAGE>   9
Guapex as a default.  Adair Oil and Guapex have agreed, if Adair Oil meets its
Earning Obligations, to share the revenues and expenses of the Alto Parana
Concession on a pro rata basis.


Risk Factors.

         The prospects of the Company are subject to a number of risks.  The
risk factors which management considers to be the highest are set forth
hereafter.  There may exist, however, other factors which constitute additional
risks but which are not currently foreseen or fully appreciated by management.

Reliance on efforts of others.

         The Company intends to form joint ventures or sell part of its
interests in order to explore on the prospects.  At this time it will depend on
other operating companies to operate its wells and properties.  Thus, the
prospects of the Company will be highly dependent upon its ability to engage
the services of competent parties to perform those functions with respect to
the Company's properties.

         With respect to the Yemen and Paraguay interests, the Company did not,
however, acquire the right to develop the properties, such responsibilities
remaining those of Adair Oil.  The Company has no rights to require Adair Oil
to perform any particular functions at any specified times.

         The Company has not yet received from Ecopetrol and the government of
Colombia their consents to the assignments of the Chimichagua Association
contract to the Company.  Accordingly, the Company has entered into a joint
operating agreement with Geopozos with respect to that property.  For a
description of the agreement, see Description of Property-The Interest in
Colombia" herein.

Ability to obtain additional capital.

         The Company anticipates that its future revenues will be derived
substantially from the Yemen, Paraguay and Colombia properties.  To explore
those properties and, if warranted, develop them, significant funding will be
required.

         In order to complete development of the properties in Colombia, the
Company could require approximately six million dollars ($6,000,000) during the
next twelve months.

         The Company acquired only a five percent (5%) net profits interest in
Adair Oil's interest in the Yemen and Paraguay contracts and did not acquire
any right to manage or develop either of those properties, such rights
remaining with Adair Oil.  The Company is therefore unable to determine the
extent of funding which Adair Oil will require under either of those contracts.
<PAGE>   10
         In order to obtain the funds the Company and Adair Oil are reviewing a
number of options.  Some of the options which may be pursued include the
formation of a joint venture; the investment by another party in equity
capital; the issuance of debt by the Company or Adair Oil, as applicable; or
borrowing from a lending institution.  The parties are limited in their ability
to borrow from banks in the United States with respect to the Yemen and
Paraguay properties and, therefore, if the borrowing from a lending institution
alternative is utilized, the parties expect to seek such borrowing from foreign
institutions.

Factors Relating to Colombia Operations.

         Colombia has indicated an intent to play a growing role in
international oil markets while expanding and privatizing its domestic gas and
electricity industries.  Officials have a stated objective of curbing the
government's spending on energy development while increasing its energy
revenues.  The plans imply growing participation in energy prospects by private
companies.

         Colombia has been beset, however, by violence and political unrest in
recent years.  These factors have had an impact on the energy infrastructure
and driven up the costs of operating in that country due to security reasons
alone.  The government responded by, among other things, providing additional
security forces to guard pipeline, production and exploration sites.  The
Company's interests in Colombia could also be affected by the policies of the
United States toward Colombia and the responses of the Colombia government to
those policies.

         Despite its political uncertainties, Colombia has strong sovereign
credit and one of South America's most stable economies.  Its economy in 1995
grew by 5.5% and has shown sustained strength in this decade.  Colombian
officials have stated they believe the country's financial reputation and range
of opportunities will attract the estimated $27 billion needed through 2000 for
new infrastructure, including big expansions oil, gas and power facilities.
Despite its laudable economic stability and improving oil and gas
prospectivity, political impediments could interfere with progress toward the
lofty energy goals.

Ability to retain Yemen and Paraguay Contracts.

         The Company anticipates that future revenues may be derived from its
net profits interests in the Yemen and Paraguay contracts.  Adair Oil has
indicated to the Company that it believes that a provision in each of the Yemen
contracts which extends the time for compliance by Adair Oil in the event of a
force majeure is applicable to the present situation.  Adair Oil has also
informed the Company that
<PAGE>   11
it has received assurances from the current government of Yemen that it agrees
with Adair Oil's position and that the government of Yemen will honor the
contracts.

         The contracts with respect to the property in Paraguay required the
holder to pay one million dollars ($1,000,000) by May 31, 1997, and another two
million dollars ($2,000,000) by July 31, 1997, to Guapex, the holder of the
applicable concessions. Adair Oil has informed the Company that it has received
assurances from Guapex that the contract will not be considered in default as a
result of the failure to make the required payment if the payment is made by
November 1, 1997.

International Operations.

         The Company anticipates that a significant portion, if not
substantially all, of its future revenues will be derived from its interests in
properties located in Colombia, Yemen and Paraguay.  The Company may also
acquire interests in other foreign countries in the future.  Currency controls
and fluctuations, royalty and tax rates, import and export regulations and
other foreign laws or policies governing the operations of foreign companies in
the applicable countries, as well as the policies and regulations of the United
States with respect to companies operating in the applicable countries, could
all have an adverse impact on the operations of the Company.

         The Company's interests could also be adversely affected by changes in
the contracts applicable to the Company's interest, including the renegotiation
of terms by the government of the country or the expropriation of interests. In
addition, the contracts are governed by foreign laws and subject to
interpretation by the courts in the applicable foreign countries.  Foreign
properties, operations and investments may also be adversely affected by the
political and social developments of the applicable countries.

Price volatility.

         The revenues generated by the Company are highly dependent upon the
prices of crude oil and natural gas.  Fluctuations in the energy market make it
difficult to estimate future prices of crude oil and natural gas.  Such
fluctuations are caused by a number of factors beyond the control of the
Company, including regional and international demand, energy legislation of
various countries, taxes imposed by applicable countries and the abundance of
alternative fuels.  International political and economic conditions may also
have a significant impact on prices of oil and gas.

Imprecise nature of reserve estimates.

         The estimations of possible and/or probable reserves of oil and gas
are imprecise.  While such estimations are based upon
<PAGE>   12
engineering and other data, the process is a subjective one consisting of
estimating underground accumulations of oil and gas that can not be measured in
an exact way.  The accuracy of an estimate is a function of the quality of
available data and of engineering and geological interpretation and judgement.
Accordingly, such estimates often change as more data becomes available and
there can be no assurances that the information regarding reserves set forth
herein will ultimately be produced.

Environmental regulation.

         The oil and gas industry is subject to substantial regulation with
respect to the discharge of materials into the environment or otherwise
relating to the protection of the environment.  The exploration, development
and production of oil and gas are regulated by various governmental agencies
with respect to the storage and transportation of the hydrocarbons, the use of
facilities for processing, recovering and treating the hydrocarbons and the
clean up of the sites of the wells.  Many of these activities require
governmental approvals before they can be undertaken.  The costs associated
with compliance with the applicable laws and regulations have increased the
costs associated with the planning, designing, drilling, installing, operating
and plugging or abandoning of wells.  To the extent that the Company owns an
interest in a well it may be responsible for costs of environmental regulation
compliance even well after the plugging or abandonment of that well.

Operating hazards and uninsured risks.

         The operation of an oil or gas well are subject to risks such as
blowouts, cratering, pollution and fires, any of which could result in damage
or destruction of the well or production facility or persons working.  The
operator of the well may be unable to purchase adequate insurance against each
of these risks.   The occurrence of a significant event could have a material
adverse affect on the Company.

General risks of the oil and gas industry.

         The Company's operations will be subject to those risks generally
associated with the oil and gas industry.  Such risks include title problems
associated with wells, weather conditions at well sites, shortages or delays in
delivery of equipment and the stability of operators and well servicing
companies.  The Company's prospects will also be impacted by the proximity of
its wells to pipelines for the distribution of any oil or gas produced.

Failure to file reports under the Exchange Act.

         The Company had filed a registration statement with the Commission
under the Securities Act of 1933 in November, 1981, and therefore became
subject to the requirement that it file
<PAGE>   13
reports thereafter under the Securities Exchange Act of 1934 (the "Exchange
Act").  The Company filed reports under the Exchange Act, including annual
reports on Form 10-K, during a portion of the 1980's.  However, the Company
experienced financial difficulties during the mid-1980's due to a downturn in
the market for oil and gas and by the late 1980's had become essentially a
dormant company.  It continued to hold interests in oil and gas wells but was
generating very little revenue.  Consequently, by 1989 the Company could no
longer afford the costs associated with audited financial statements.  The
Company filed its Form 10-K under the Exchange Act in 1989 without including
audited financial statements and has continued to make 10-K filings under the
Exchange Act without audited financial statements.  The Company may also not
have complied with certain other formalities required by the Exchange Act with
respect to the 10-Ks and other reports due thereunder.

ITEM 2.  Description of Property.

         The Company holds interests in existing oil and gas wells in the
United States, has interests in proved producing properties in Colombia and
holds interests in contracts relating to properties in Yemen and Paraguay.  The
Colombia, Yemen and Paraguay properties are intended to be explored and, if
warranted, developed as oil and gas properties.

The United States Properties.

         The Company holds working interests in oil and gas wells located
throughout the United States. The Company holds an interest in seventy-nine
(79) oil and gas wells, with a net interest of 1.68 oil wells and 7.91 gas
wells.  The Company has received a report from a petroleum engineer which
indicates that as of May 31, 1997, there were proved reserves of 778 barrels
attributable to the Company's net interest in the oil wells and proved reserves
of 124.8 million cubic feet attributable to the Company's net interest in the
gas wells.

Yemen Property Interests.

         The Company holds interests in two properties, one located in the
country of Yemen and the other located off the coast of Yemen.  The Company
acquired five percent (5%) of the interests of Adair Oil in the profits to
which Adair Oil is entitled from the production of oil from those properties.
Adair Oil, through an affiliated company, acquired the interests from the
government of Yemen pursuant to contracts dated June 20, 1993.  One contract
relates to an area generally described as Block 24 offshore of the Hodeidah
Province (the "Hodeidah Contract"), covering an area of approximately two
million five hundred thousand (2,500,000) acres and the second contract relates
to an area generally described as Block 28 in the Shabwa Province (the "Shabwa
Contract") and covers approximately one million (1,000,000) acres.  Other than
the geographical locations to which they
<PAGE>   14
apply, the Hodeidah Contract and the Shabwa Contract each contains
substantially identical terms, except as to the initial exploration periods, as
defined in the contracts, and the funds required to be expended by the holder
for exploration.  Collectively, the Hodeidah and Shabwa contracts are referred
to as the "Yemen Contracts."

         The Yemen Contracts assign to the holder the exclusive right to
explore for oil in the designated areas and to conduct petroleum operations if
warranted.  The government of Yemen has retained a ten percent (10%) royalty
interest and has retained the rights to all gas which might be discovered in
the area.  The initial exploration period for the Hodeidah Contract was thirty
months from the effective date of the contract, during which time the holder
was required to expend eighteen million dollars ($18,000,000) toward the
acquisition and processing of seismic data relating to the area and the
drilling and evaluation of at least two wells.  The initial exploration period
for the Shabwa Contract was thirty-six months from the effective date of the
contract, during which time the holder was required to expend fifteen million
dollars ($15,000,000) toward the acquisition and processing of seismic data
relating to the area and the drilling and evaluation of at least two wells.
Adair Oil believes that the holder was prevented from doing the before
mentioned work program as a result of force majeure, as defined in the
contracts, and that it has until December 31, 1998, to perform its obligations
under the Hodeidah Contract and until December 31, 1998, to perform its
obligations under the Shabwa Contract.  The current government of Yemen has
indicated to the representative of Adair Oil that it is in agreement with the
position taken by Adair Oil.

         Following the initial exploration period, the holder has the option to
enter into a second exploration period which would extend its rights to further
explore the designated area for, in the case of the Hodeidah Contract, thirty
(30) months and, in the case of the Shabwa Contract, thirty-six (36) months.
After completion of the exploration period, twenty-five percent (25%) of the
area covered by each of the Yemen Contracts is then relinquished back to the
Yemen government, except any area which has been converted into a development
area.

         If Adair Oil determines that sufficient quantities of oil exist to
warrant development of an area it must apply to the Ministry of Oil and Natural
Resources of Yemen for designation of that area for development.  The Ministry
is to grant such designation if the holder is in compliance with the terms of
its contract.

         The Company has received a report from an independent petroleum
engineer which indicates that from the information which was made available to
the engineer, the proved or probable reserves could not be quantified and the
project should be considered as strictly exploratory.
<PAGE>   15
Paraguay Property Interests.

         The Company holds a five percent (5%) net profits interest in Adair
Oil's interest in a Farmout Agreement relating to the Alto Parana Concession in
the Republic of Paraguay.  Adair Oil acquired the interests of an affiliated
company in that agreement in June, 1997.  The affiliate acquired a sixty
percent (60%) participating interest in the Alto Parana Concession on May 31,
1997, from Guapex.  The Alto Parana Concession relates to approximately
3,292,900 hectares.

         The Company also holds a five percent (5%) net profits interest in
Adair Oil's interest in a Farmout Agreement relating to the San Pedro
Concession in the Republic of Paraguay.  Adair Oil acquired the interests of an
affiliated company in that agreement in June, 1997.  The affiliate acquired a
ninety-nine percent (99%) participating interest in the San Pedro Concession on
May 30, 1997, from Guapex.  The Alto Parana Concession relates to approximately
2,400,000 hectares.

         Each of the interests in the Paraguay contracts are to be assigned
when the holder has complied with the Earning Obligations specified in the
relevant contracts.  For a description of those obligations, see "Business-The
Interests in Paraguay" herein.

         The Company has received a report from an independent petroleum
engineer which indicates that from the information which was made available to
the engineer, the proved or probable reserves could not be quantified and the
project should be considered as strictly exploratory.

The Colombia Properties.

         In 1997, the Company acquired, subject to certain consents as
hereafter described, rights with respect to a contract relating to the
exploration, drilling and development of oil and gas property in Colombia. The
asset consists of the rights and obligations of Geopozos with respect to a
contract, known as the Chimichagua Association contract (the "Association
Contract").  The Association Contract grants the right to explore, drill and
extract hydrocarbons from a specified area in Colombia.  The Association
Contract relates to an area of approximately 164,900 hectares (a hectare is
2.47 acres) in the Magdalena valley of Colombia, approximately 500 miles north
of Bogota.  The Association Contract was originally acquired by Esso Colombia
in 1988 and, following an intervening assignment, was acquired by Geopozos on
September 14, 1996.

         The Association Contract, between Ecopetrol, the national oil company
of Colombia, and the holder, provides that the parties shall share equally the
hydrocarbons produced from the relevant properties, subject to an overriding
royalty interest of twenty percent (20%) which is reserved for Ecopetrol, and
the
<PAGE>   16
expenses of development of the properties.  The holder is responsible for the
exploration of the properties but has the right to receive reimbursement of
those costs with respect to fields which are commercially developed by the
parties.  The effective date of the Association Contract was January 20, 1989,
and the contract terminates for all purposes twenty-eight (28) years
thereafter.  The contract provides for an exploration period of six (6) years,
subject to certain extensions, and an exploitation period of twenty-two (22)
years.  Under the terms of the contract a portion of the property which has not
been commercially developed is reduced over a period of years, beginning in the
sixth year.  In a letter to the Company dated August 4, 1997, Geopozos
indicated that fifty percent (50%) of the original area covered by the
Association Contract had been returned to Ecopetrol and that Ecopetrol had not
issued any declarations of commerciality with respect to the remaining area.

         In connection with the agreement between Geopozos and the Company,
Geopozos retained a two percent (2%) overriding royalty interest in
hydrocarbons produced from the properties developed under the Association
Contract.  Geopozos also agreed to act as the operator under the Association
Contract for a period of up to twelve (12) months until the Company or its
assignee has been approved by Ecopetrol and the Ministry of Mines and Energy of
Colombia.  The parties also agreed to enter into joint operating agreement
covering those operations.  The agreement is to provide, among other things,
that Geopozos will be allowed to mark up expenditures which it incurs, and
which have been agreed to in advance, by ten percent (10%).

         The Association Contract provides, among other things, that Geopozos
was required to perform certain exploration of the properties prior by December
18, 1996, and that the consents of Ecopetrol and the Colombian Ministry of
Mines and Energy are required in order for the assignment to the Company from
Geopozos to be effective.  On August 4, 1997, the Company received a letter
from Geopozos which indicated that (i) Geopozos has fulfilled all of its
obligations to Ecopetrol, (ii) Geopozos has provided Ecopetrol with all
necessary and requested technical information and data and (iii) the
Association Contract is valid.

         The Company has received a report from a petroleum engineer which
indicates that the information provided to him by the Company with respect to
the properties in Colombia indicates that there are 22.150 billion cubic feet
of gas which would be classified as proved reserves.

         Geopozos and the Company entered into a Joint Operating Agreement
("JOA") effective March 5, 1997, and terminating upon termination of the
Association Contract.  The JOA provides, among other things, that Geopozos will
remain as Operator, for the purpose of the Association Contract and the JOA,
for a period of time ending no sooner than twelve months from the effective
date
<PAGE>   17
of the JOA, or until the Company is approved as Operator by Ecopetrol,
whichever occurs first.  Under the JOA, the Company owns 100% of the benefits
of the Association Contract and is responsible for 100% of the costs and
expenses of exploration and exploitation incurred by Geopozos, as Operator.
These costs and expenses are payable by the Company on a quarterly basis,
either in advance or at the end of the quarterly period, at the election of
Geopozos.  As security against the Company's obligation to pay these costs and
expenses, Geopozos retains an interest in the Company's rights in the
Association Contract as well as an interest in and a lien against any
production to which the Company has a right under the Association Contract.

Item 3.  Legal Proceedings.

         In July, 1985, the Company entered into a revolving credit agreement
with a lending bank.  This note was collateralized by mortgage, deed of trust
and assignment of production on the majority of the Company's oil and gas
properties, causing the majority of the revenues of these properties to be paid
directly to the lender.  The Company became delinquent in the payment of
principal and interest on the note during 1987.  In January, 1988, the lender
was placed in receivership, and in May, 1989, the FDIC sold this note to a
third party.  The third party holder failed to collect on this note.  In the
meantime, the Company held in suspense the revenues which otherwise might be
payable to the third party holder under the terms of this note.  Eventually,
the Company filed an Action for Declaratory Judgment against the third party
holder in the 281st Judicial District Court of Harris County, Texas.  In this
litigation, the Company requested the court to determine the rights of the
third party holder with regard to this note and the security instruments
collateralizing this note.  On March 21, 1997, the court in this proceeding
entered a default judgment against the third party holder.  This default
judgment declared the third party holder's interest in the note and the
security instruments given as collateral thereunder to be null and void and of
no force and effect, being barred by statute of limitation.  Further, the court
declared that the $252,476 previously held in suspense in lieu of payment to
the third party holder to be the property of the Company, free and clear of any
claims of the third party holder.

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

         A special meeting of shareholders of the Company was held on July 8,
1997.  Proxies with respect to the matters to be acted upon at the meeting were
not solicited by management.  At the meeting shareholders approved an amendment
to the Company's articles of incorporation to change the name to Adair
International Oil and Gas, Inc., to increase the number of authorized shares of
common stock from 20,000,000 shares to 100,000,000 shares and to change the par
value of the shares of common stock from thirty cents ($.30) to no par value.
<PAGE>   18
Shareholders were also requested to ratify the transaction with Adair Oil.  A
total of 16,502,480 shares were voted on each of the issues voted on at the
meeting, with all shares voting in favor of each of the issues and no shares
voting against any of the proposals.

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

         The Company's stock has been traded very infrequently during the past
two years and, to the best of the Company's knowledge, no broker made a market
or regularly submitted quotations for the Company's stock during that time.  In
the last two fiscal years less than one thousand shares were traded in any
year.

         As of July 31, 1997, there were approximately 800 holders of the
Company's common stock.  The Company has not paid any cash dividends on its
common stock during the past two fiscal years.  The Company may only pay
dividends from surplus.

Recent Sales of Unregistered Securities.

         The Company issued shares of its common stock to directors as
compensation for acting as directors of the Company and to one employee without
the shares being registered under the Securities Act of 1933 (the "Securities
Act") in reliance upon the exemption contained in Section 4(2) promulgated
under the Securities Act.  The directors of the Company had not received any
compensation for serving as directors for a number of years.  In recognition of
the many years of service by the various directors without the payment of
compensation, the Company issued as aggregate of nine hundred ninety thousand
(990,000) shares to four directors.  For a description of the transaction, see
"Item 10.  Executive Compensation" herein.  At the same time that the shares
were issued to the directors, the Company also issued ten thousand (10,000)
shares to a long time employee of the Company in recognition of the employee's
many years of service to the Company.

         The Company sold an aggregate of six million (6,000,000) shares of its
common stock in exchange for assets consisting of rights with respect to
properties located in Colombia.  For a description of the transaction, see
"Item 1.  Description of Business" and "Item 2. Description of Properties"
herein.  The shares were sold in reliance upon the exemption contained in
Section 4(2) under the Securities Act.

         The Company sold an aggregate of ten million two hundred thousand
(10,200,000) shares of common stock on June 16, 1997, in exchange for certain
assets consisting of a portion of the rights to contracts respecting properties
in Yemen and Paraguay.  For a description of the transaction, see "Item 1.
Description of Business" and "Item 2.  Description of Properties" herein.  The
shares were sold in reliance upon the exemption contained in
<PAGE>   19
Section 4(2) under the Securities Act.

         In July, 1997, the Company sold one million (1,000,000) shares of its
restricted common stock for a price of twenty cents ($.20) per share to two
individuals.  The shares were sold in reliance upon the exemption contained in
Section 4(2) under the Securities Act.


Item 6.  Management's Discussion and Analysis or Plan of Operation.

         The following summary of the Company's financial position and results
of operations should be read in conjunction with the Financial Statements,

</TABLE>

         The increase in oil and gas property costs includes $3,600,000 from
the acquisition of foreign oil and gas property in Colombia described in Note 2
to the financial statements.

         Oil and Gas Sales-  The increase from $118,705 to $204,633 reflects
approximately $100,000 of revenues which were received in May 1997 by the
Company from release of suspended production revenues held in connection with
the promissory note described in Note 3 to the financial statements.  The
release of revenues results from the cancellation of such indebtedness.
<PAGE>   20
         Operating Expenses-Lease operating expenses increased from $15,479 to
$51,249 due to the inclusion of additional production expenses on the revenues
which had been suspended.  General and administrative costs increased from
$44,214 to $155,355 due to last quarter business activity and the inclusion of
approximately $23,000 of legal expenses in connection with the Colombia
acquisition described in Note 2.  Payroll expenses increased by approximately
$35,000 attributable to personnel associated with the acquisition.

         The oil and gas production which the Company holds in the United
States continued to decline during 1997.  Further declines in domestic
productions are anticipated and the Company intends to focus future plans on
exploring and developing foreign reserves acquired in the acquisition described
in Notes 2 and 12.  Future revenues from the Company's domestic production at
May 31, 1997 is expected to be minimal.

         Net income for the fourth quarter ended May 31, 1997 was $672,172 or
$.10 per share on revenues of $873,314 versus a net income at $4,977 or $.00
per share on revenues of $95,683 for the quarter May 31, 1996.  The fourth
quarter of fiscal year ended May 31, 1997 benefitted from non-recurring
forgiveness of debt income aggregating $722,530 or $.07 per share from the
cancellation of a promissory note which had been outstanding since January 1,
1987.

         In 1995 and prior the financial results of the Company were
insignificant because the Company has not conducted any oil and gas exploration
or development activities since May 31, 1989.  Activity from May 31, 1989
through May 31, 1997 focused on production from the Company's domestic oil and
gas reserves and cost cutting.

         Inflation's Impact-Inflation was not a significant factor in 1997
operations and is not expected to be a major factor in 1998 operations.

Liquidity and Capital Resources

         Cash provided by operating activities increased by $124,618 during the
year ended May 31, 1997.  Such cash flow is not sufficient to finance the
future exploration and development of the Company's foreign oil and gas
properties.  Therefore the Company will continue efforts to farm out high risk
prospects from inventory to oil companies with greater resources thereby
avoiding the risk and cash drain of exploratory drilling activities.  Given the
present economic conditions in the industry , no assurances can be made that
the Company will be successful in its efforts.  The Company is also pursuing
bank lines of credit to supplement future working capital requirements.

Item 8.  Changes to and Disagreements With Accountants on Accounting and
Financial Disclosures.


         On July 15, 1997, the Company engaged the services of Braden, Bennink,
Goldstein, Gazaway & Company, PLLC, Houston, Texas, to conduct an independent
audit of the Company's financial statements through the year ended May 31,
1997.  The Company had not engaged any firm to conduct an independent audit of
the Company's financial statements since 1989.

Dresser Engineering Co. from 1995 to 1997.  Since 1990 Mr. Alghani has served
as an executive officer of Adair Oil International.

         Abdul Aziz M. Al-Abdulkader has been involved with a number of
companies during the past five years as an officer, director and investor, the
majority of which are located in the Middle East.  His primary employment has
been the management of AMA group of companies located in Saudi Arabia, whose
activities include furniture manufacturing and retailing, maintenance
operations of residential compounds, ownership of restaurants and metal
insulation production.

Section 16(a) Beneficial Ownership Reporting Compliance.

         No reports were filed on Forms 3, 4 or 5 under the Exchange Act during
the last fiscal year.  Earl Roberts, a current officer and director of the
Company, and former directors, Robert Steelhammer, Jim Shindler and Raymond
Kerr, should each have filed two Form 4s with respect to shares which they
acquired during the year.  Current directors, John Adair, Jalal Alghani and
Abdul Aziz M. Al-Abdulkader should each have filed a Form 3 after becoming
directors.  Petroleum Exploration Services, Inc. should have filed a Form 3
when it became the beneficial owner of more than ten percent (10%) of the
Company's common stock.  Adair International Oil Canada, Inc. should have filed
a Form 3 when it became the holder of more than ten percent (10%) of the
Company's common stock.

Item 10.  Executive Compensation.

          During the past three fiscal years the Company has employed only one
person as an executive officer.  No executive officer received any compensation
from the Company during the past three
<PAGE>   23
fiscal years.  Mr. Earl Roberts, the president and chief executive officer of
the Company during each of those years, received shares of common stock of the
Company as a director during the fiscal year ended May 31, 1997, as hereafter
described.

         The directors of the Company did not receive any compensation for
serving as directors for a number of years.  On August 1, 1996, the directors
determined that, in recognition of the many years of service by the various
directors without the payment of compensation, the Company should issue shares
of its common stock to the directors.  The issuance of the shares was
contingent upon the completion of the transactions pursuant to which the
Company was to acquire the interests in Colombia.  See "Item 1.  Description of
Business."  Thus, on March 14, 1997, the Company issued 321,750 shares of its
common stock to Earl Roberts for service as a director and 222,750 shares of
its common stock to each of the remaining directors, Robert Steelhammer, Jim
Shindler and Raymond Kerr.  In 1997 the Company incurred legal fees of $25,373
which were payable to a law firm of which Raymond Kerr, a director of the
Company was a partner.

         The Company has no employment contracts with any of its executive
officers.  Beginning in June, 1997, the Company agreed to pay John Adair, Earl
Roberts and Jalal Alghani a salary of five thousand dollars ($5,000) per month
each.

REPORT OF INDEPENDENT ACCOUNTANTS


To the Board of Directors
Adair International Oil and Gas, Inc.

         We have audited the accompanying balance sheet of Adair International
Oil and Gas, Inc. as of May 31, 1997, and the related statements of operations,
changes in stockholders' equity and cash flows for each of the two years ended
May 31, 1997 and 1996. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.

         We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. An audit
also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

         In our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of Adair International
Oil and Gas, Inc. as of May 31, 1997, and the results of their operations,
changes in stockholders' equity and their cash flows for each of the two years
ended May 31, 1997 and 1996, in conformity with generally accepted accounting
principles.

         As discussed in Note 2 to the financial statements, the realization of
significant assets is contingent upon obtaining financing sufficient to fund
the necessary development costs. Final arrangements for such financing has not
yet been obtained. As described in Notes 2 and 6, in connection with the asset
acquisition described in Note 2, shares have been issued to foreign
corporations whose ownership is unknown to the company and we were unable to
verify management's representations that these entities are not related parties.
See also, Note 11 for subsequent events which have occurred since May 31, 1997.

                         NOTES TO FINANCIAL STATEMENTS

1.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

                  Adair International Oil and Gas, Inc. (Formerly Roberts Oil
         and Gas, Inc.)("the Company") was incorporated under the laws of the
         state of Texas on November 7, 1980. Since inception the Company's
         primary purpose has been the exploration, development and production
         of oil and gas properties in the United States. During the year ended
         May 31, 1997, as described in Note 2, the Company acquired proven
         properties located in Colombia. After May 31, 1997 as described in
         Note 11, a 51% interest in the Company's outstanding Common Stock was
         acquired by Adair Oil and Gas International of Canada, Bahama
         Corporation, and the Company name was changed to Adair International
         Oil and Gas, Inc.

         ACCOUNTS RECEIVABLE

                  Accounts receivable result from revenues attributable to
         non-operating interests in domestic oil and gas properties. No reserve
         for bad debts exists because they are all deemed to be fully
         collectible.

         CASH AND CASH EQUIVALENTS

                  For purposes of the statement of cash flows, the Company
         considers all highly liquid debt instruments purchased with a maturity
         of three months or less to be cash equivalents. The carrying amount
         approximates fair value because of the short maturities of those
         instruments.

<PAGE>   33

         PROPERTY AND EQUIPMENT

                  The Company follows the full-cost method of accounting for
         its oil and gas properties and, accordingly, capitalizes all costs
         associated with property acquisition, exploration and development in
         separate cost centers for each country. Such costs do not exceed the
         sum of the present value of estimated proved reserves and the value of
         unproved properties including consideration for income tax benefits.

                  Depreciation and depletion of oil and gas properties is
         computed using all capitalized costs and estimated future development
         and abandonment costs, exclusive of oil and gas properties not yet
         evaluated, on a unit of production method based on estimated proved
         reserves.

                  The cost of other categories of property and equipment are
         depreciated on a straight-line basis over the estimated useful lives
         of the assets for financial statement purposes and accelerated methods
         for federal income tax purposes.

                  Gains and losses on dispositions of oil and gas properties
         are recognized only when there is a significant change in the
         relationship between costs and proved reserves. Gains or losses on
         dispositions of assets other that oil and gas properties are credited
         or charged to operations. Expenditures for repairs and minor
         replacements are charged to expense.

                  In accordance with the full cost method of accounting, the
         net capitalized costs of oil and gas properties are not to exceed
         their related estimated future net revenues discounted at 10 percent,
         net of tax considerations, plus the lower of cost or estimated fair
         market value of unproved properties.

                  Substantially all of the Company's exploration, development
         and production activities are conducted jointly with others and,
         accordingly, the financial statements reflect only the Company's
         proportionate interest in such activities.

         INCOME TAXES

                  The Company accounts for income taxes pursuant to the asset
         and liability method of computing deferred income taxes. Deferred tax
         assets and liabilities are established for the temporary differences
         between the financial reporting bases and the tax bases of the
         Company's assets and liabilities at enacted tax rates expected to be
         in effect when such amounts are realized or settled. Valuation
         allowances are established, when necessary, to reduce deferred tax
         assets to the amount expected to be realized.

         SIGNIFICANT ACCOUNTING ADJUSTMENTS

                  The full cost pool was written down by $55,785 and $75,122 in
         1997 and 1996 respectively. The write-down primarily reflects a
         decrease in the valuation of proved reserves. Future write-downs of
         the full cost pool may be required if (i) declining prices and other
         unfavorable industry trends continue, (ii) production is not replaced
         by reserve additions and (iii) further impairments of unevaluated
         properties or downward revisions to proved reserves are required.

         EARNINGS PER SHARE INFORMATION

                  Earnings per share are computed by dividing earnings (loss)
         by the weighted average number of common shares outstanding adjusted
         for conversion of common stock equivalents, where applicable
         outstanding during the period. The calculation of fully diluted
         earnings per common share additionally assumes the conversion of the
         cumulative convertible preferred stock.
<PAGE>   34
         USE OF ESTIMATES

                  The preparation of financial statements in conformity with
         generally accepted accounting principles requires management to make
         estimates and assumptions that effect 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.

         RECLASSIFICATIONS

                  Certain previously reported financial information has been
         reclassified and prior unaudited results have been restated to conform
         to the current year's presentation and to give effect to adjustments
         resulting from the audit.

2.       ACQUISITION

                  On February 27, 1997, Roberts Oil and Gas, Inc. (The
         "Company") entered into an agreement with Geopozos, S.A. ("Geopozos")
         pursuant to which it agreed to issue shares of its common stock to
         Geopozos (the "Geopozos Agreement"), subject to approval by the
         Company's board of directors and to be implemented on May 20, 1997. As
         part of the Geopozos Agreement the Company agreed to issue to Geopozos
         two million (2,000,000) shares of its common stock and a promissory
         note in the principal amount of six hundred thousand dollars
         ($600,000) in exchange for certain assets. In connection with the
         acquisition of those assets, on March 14, 1997, the Company was
         directed by ROGI International S.A., (a party to the Geopozos
         agreement and an unrelated company incorporated under the laws of
         Panama), to issue the aforementioned two million (2,000,000) shares of
         its common stock to two entities and four million (4,000,000) shares
         of its common stock to seven foreign corporations and one individual
         in exchange for the assets being acquired.

                  The assets which were transferred to the Company in exchange
         for the promissory note and the issuance of shares consisted of a
         contract, known as the "Chimichaqua Association" contract relating to
         a 100% working interest covering rights to explore and drill for
         hydrocarbons in specified locations in Colombia. The assignment of the
         interest from Geopozos to the Company is subject to the approval of
         the Colombian Ministry of Mines and Ecopetrol (the Colombian
         government owned oil company).

                  The shares issued in connection with this acquisition were
         authorized but unissued shares of the Company. To date, the Company
         has not been informed of the relationship or affiliation, if any,
         among the entities to whom these shares were issued.

                  At May 31, 1997 the property acquired contained proven
         non-producing gas reserves, as described in Note 9, " Supplemental Oil
         and Gas Disclosures", which was recorded at a cost basis of
         $3,600,000, and issued 6,000,000 common shares valued at $0.50 per
         share. On March 5, 1997 the parties to this acquisition executed a
         joint operating agreement which requires Geopozos to operate the
         property for an initial period of twelve months.

                  Pursuant to the purchase agreement, Geopozos may nominate one
         individual to serve on the Board of Directors and will receive a 2%
         overriding royalty in all hydrocarbons produced from the properties.
         At May 31, 1997 

<PAGE>   35

         the Company was in process of determining a development plan for the
         acquired property. Realization of the value of these reserves is
         contingent upon the Company obtaining financing sufficient to fund the
         development costs. Firm commitments for such financing have not yet
         been obtained.

3.       NOTES PAYABLE AND LONG-TERM DEBT

                  The Company issued a $600,000 unsecured promissory note to
         Geopozos in connection with the acquisition of the Colombia properties
         described in Note 2. The note bears no interest and is due and payable
         in full from first funds raised for the Chimichaqua Association
         Development Project, if Ecopetrol (the Colombia National Oil Company)
         grants commercialization on the first well in the project. The Company
         may be able to recover a like amount from recovered expenses paid by
         Ecopetrol. At May 31, 1997 the note was not classified as current
         because events which must occur to make the note due and payable are
         not expected to occur within the next twelve months. The note has not
         been discounted because it has no maturity date and the ultimate date
         of payment cannot be determined.

                  In October , 1986, the Company renewed, rearranged and
         extended a revolving credit agreement and related promissory note
         dated July 1, 1985 in the original principal sum of $900,000. The note
         was payable on or before December 31, 1991. As no demand for full
         payment of outstanding principal and interest was made prior to the
         maturity date, monthly installments of principal and interest of
         $19,631 were due and payable commencing January 1, 1987 through
         maturity. The note was collateralized by a mortgage, deed of trust and
         assignment of production on the majority of the Company's oil and gas
         properties. The majority of revenues from the Company's oil and gas
         production were received directly by the lender. Payments including
         this note and preferred stock dividends and redemptions were
         administered by the lender. In January of 1988, the lending bank was
         placed into receivership and the note began to be administered by the
         Federal Deposit Insurance Corporation (FDIC). In May 1989, the FDIC
         sold the note to a third party individual. There were no revisions or
         modifications to the original note agreement after the FDIC or the
         third party individual

         assumed administration of the note. The majority of revenue from the
         Company's oil and gas production were forwarded to the new third party
         and subsequently, placed in suspense. Preferred stock dividends, note
         payments and payments of operating and general and administrative
         expenses of the Company were administered by the new third party.

                  On March 21, 1997 in a Houston District Court, the Company
         received a declaratory judgement ruling that the holder was barred
         from collection by the statute of limitations which canceled the note.
         Production revenues which had been held in suspense since 1989,
         aggregating $ 252,476 were released and deposited by the company in
         May 1997. The promissory note was removed from the balance sheet and
         forgiveness of debt income of $ 722,530 was included in the results of
         operations during the year ended May 31, 1997.

                  The Company had no long term leases at May 31, 1997 and May
         31, 1996. Rental expense for 1997 and 1996 was $6,897 and
         $9,218,respectively.

4.       REDEEMABLE CUMULATIVE CONVERTIBLE PREFERRED STOCK

                  During the fiscal year 1986 the shareholders of the Company
         authorized 5,000,000 shares of redeemable cumulative convertible
         preferred stock (preferred stock) for $100 per share. The preferred
         stock is non-voting and was convertible to 166.67 shares of common
         stock for each share of preferred stock at any time at the
         shareholders option within five years from the date of issuance.

                  The preferred stock was to accrue dividends at the rate of
         12% per annum to be funded by a sinking fund account at a bank, to the
         extent, and only to the extent, that revenues from certain oil and gas
         properties being deposited with the bank exceeded operating expenses
         and agreed bank debt repayment. Dividends were accumulated and the
         first quarterly dividend payment was made on January 5, 1987.
         Thereafter, the amount initially paid for the preferred shares were
         scheduled for repayment of $100 per share plus accrued dividends in
         twenty equal quarterly installments beginning April 5, 1987. The
         Company was unable to make any of the scheduled principal and interest
         payments on its preferred stock.

                  The preferred stock contained a conversion feature allowing
         the holders to convert the preferred shares to common stock. At the
         earlier of five years from the stock issuance date or at liquidation
         of related shareholder notes, if any, the preferred shareholder could
         elect one on the following redemption options:

             a.       To convert each share of preferred stock to 166.67 share
                      of common stock;
             b.       To have the Company redeem the preferred stock at $150 
                      per share; or
             c.       To redeem the preferred stock utilizing a combination 
                      of (a) and (b).

                  The premium over issue price of $50 per share was accreted
         over twenty quarters using the interest method.

                  Prior to May 31, 1997 all preferred shares were converted to
         common stock, except for 600 shares held by three shareholders. Legal
         counsel for the Company determined that, pursuant to the preferred
         stock agreement, the preferred shareholders who failed to convert no
         longer retained their redemption rights because the statute of
         limitations on such rights expired prior to May 31, 1997. The
         preferred stock purchase agreement provides that, in such
         circumstances, the Company may convert all remaining preferred shares
         to common stock at the rate of 166.67 shares of common, subject to
         adjustment for a 30:1 reverse stock split and the stock dividend on
         May 12, 1997 described in Note 10. It is anticipated that in August,
         1997 the Company will issue approximately 6,666 common shares in
         redemption of the remaining preferred stock outstanding at May 31,
         1997. Such shares are considered common stock equivalents in computing
         fully diluted earnings per share.

5.       INCOME TAXES

                  The company adopted Statement on Financial Accounting
         Standards Opinion No. 109, "Accounting for Income Taxes" effective
         June 1, 1994. The effect of this change did not have significant
         impact on the Company's financial statements.

                  The difference between the approximate effective rates
         presented for federal income taxes and the amounts which would be
         determined by applying the statutory federal rates for fiscal 1997,
         and fiscal 1996, to earnings before provision for federal income taxes
         are presented below:

         </TABLE>


                  Deferred taxes result primarily from the writedown of the
         domestic full cost pool for book purposes which was not deductible for
         tax purposes. At May 31, a valuation allowance was established to
         reduce the deferred tax asset resulting from the benefit of net
         operating loss carryforwards. Such allowance was established because
         Section 382 of the Internal Revenue Code limits the use of operating
         loss carry forwards and other tax attributes in the event of a greater
         than 50% change in ownership as described in Notes 2 and 11. Because
         of the ownership changes explained in Notes 2 and 11, all net
         operating loss carryforwards at May 31, 1997, no longer exist.

6.       RELATED PARTY TRANSACTIONS

                  During the years ended May 31, 1996 and 1997, the Company
         incurred approximately $25,373 and $7,692 , respectively, in legal
         costs paid to a Director. At May 31, 1997, $50,830 was owed.

                  As described in Note 2, the Company has not been informed of
         the relationship or affiliation, if any, of the entities who obtained
         stock in connection with that acquisition.

7.       COMMITMENTS AND CONTINGENCIES

                  The Company is subject to extensive Federal, state, and local
         environmental laws and regulations. These requirements, which change
         frequently, regulate the discharge of materials into the environment.
         The Company believes that it is in compliance with existing laws and
         regulations.

         ENVIRONMENTAL CONTINGENCIES

                  The oil and gas industry is subject to substantial regulation
         with respect to the discharge of materials into the environment or
         otherwise relating to the protection of the environment. The
         exploration, development and production of oil and gas are regulated
         by various governmental agencies with respect to the storage and
         transportation of the hydrocarbons, the use of facilities for
         processing, recovering and treating the hydrocarbons and the clean up
         of the sites of the wells. Many of these activities require
         governmental approvals before they can be undertaken. The costs
         associated with compliance with the applicable laws and regulations
         have increased the costs associated with the planning, designing,
         drilling, installing, operating and plugging or abandoning of wells. To
         the extent that the Company owns an interest in a well it may be
         responsible for costs of environmental regulation compliance even well
         after the plugging or abandonment of that well.

8.       MAJOR CUSTOMERS

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS AND CHANGES THEREIN 
RELATING TO PROVED OIL AND GAS RESERVES

The following information has been prepared in accordance with Statement of
Financial Accounting Standards No. 69, which requires the standardized measure
of discounted future net cash flows to be based on sales prices, costs and
statutory income tax rates in effect at the time the projections are made and a
10 percent per year discount rate. The projections should not be viewed as
estimates of future cash flows nor should the "standardized measure" be
interpreted as representing current value to the Company.

10.      STOCK DIVIDEND

                  In May , 1997 the Board of Directors approved a stock
         dividend on the basis of a one share dividend for each share owned for
         all shareholders of record at May 12, 1997. In connection with this
         dividend 2,000,000 shares were issued.

11.      SUBSEQUENT EVENTS

                  On June 16, 1997, the Company acquired a five percent net
         profits interests in exploration acreage totaling 14 million acres in
         Paraguay, South America and 3.5 million acres in Yemen from Adair Oil
         and Gas International Canada, Inc. in exchange for 10,200,000 voting
         shares in common stock. The initial 10,000,000 shares were newly
         issued and the additional 200,000 came from the Company treasury stock
         which, together, represent 51% of the Company's issued and then
         outstanding common stock. The Company will record the cost of the
         acquisition at $5,100,000 using a stock valuation of $0.50 per share.
         Under the purchase agreement members of the Board of Directors at May
         31, 1997 resigned and were replaced by a new board headed by the
         Chairman and Chief Executive Officer of Adair. The new board retained
         the services of Earl K. Roberts, as 


<PAGE>   41

         President and Chief Operating Officer. On July 9, 1997 the company 
         changed its name to Adair International Oil and Gas, Inc. and
         appointed three new directors. It is expected that two additional
         board members will be added in the future.

                  The development of the Yemen and Paraguay properties are
         expected to be funded by a joint venture. The Company's net profits
         interest in such properties does not require it to fund any of the
         cost of exploration or development of the Yemen or Paraguay
         properties.

                  On June 27, 1997 the Bylaws provided for an increase in
         Directors from four to six.

                  On July 25, 1997 the Board of Directors increased the number
         of authorized common shares to 100,000,000 and changed those shares to
         no par value.

                  In July 1997 the Company sold 1,000,000 restricted common
         shares to one of the new directors for $200,000.

removed if the votes cast against his removal would be sufficient to elect him
