Item 2. Management's Discussion and Analysis or Plan of Operation.

General

        Southwestern Water Exploration Co. (the "Company"), formerly Star
Acquisitions Corporation, was incorporated in the State of Colorado on June 10,
1987. The Company's activities from inception consisted primarily of reviewing
possible business opportunities and acquisitions, and maintaining the business
entity. The Company had only nominal net assets and no operational activities
from the fiscal years 1987 through 1995 and all expenses incurred were solely
related to maintaining the entity and reviewing potential business
opportunities.

        The Company intends to develop and market potable water throughout the
American Southwest. During its development stage, the Company acquired the
Database which it believes will provide surface drilling locations to mine deep
(below 2,000 ft) subsurface aquifers.

        The Company has identified a number of sites which it believes will
provide potable water, including a significant water reservoir in Nevada, by
utilizing the Database. Once developed, it is the intent of the Company to
market the water from these sites. If the marketing effort is unsuccessful, the
Company intends to sell the water rights to these sites. The Database provides
specific information including surface location, depth(s) of aquifers,
temperature, production capability, and mineral properties from wells previously
drilled for hydrocarbons and subsequently abandoned.

        Management believes that the Company can satisfy its cash requirements
from existing funds for another three months. The Company intends to meet its
future capital needs by raising additional funds through a private placement of
its securities. The Company anticipates that funding of future operations will
be provided by the completion of this private placement for a minimum of $1.5
million. There can be no assurances, however, that the Company will be
successful in the completion of the private placement. In the event the private
placement is not successful, or fails to raise sufficient funds, the Company may
seek alternative financing in the form of short-term or long-term debt or
securities convertible into common stock of the Company.

        In the event the private financing is successful, the Company intends to
engage Messrs. Misner and Webb as full-time employees and pay them monthly
salaries of approximately $5,000 per month, respectively. Even if the amount
raised in the private placement meets the Company's expectations, the Company
does not plan to hire additional employees or purchase or acquire plant or
significant equipment. The Company will meet its personnel, drilling and
pipeline requirements by contracting for these services with third parties.

                                OTHER INFORMATION

Item 1. Legal Proceedings.

        The Company is not a party to any legal proceedings which in the opinion
of Company's management are individually or collectively, material to its
business.

Item 2. Changes in Securities and Use of Proceeds.

(c)  Recent Sales of Unregistered Securities

        From September 30, 1994 to September 30, 1997, the Company issued
approximately 486,000 Units to certain sophisticated individuals at a price per
Unit of $1.00 for a total offering of $486,000. Each Unit consisted of one share
of its $.001 par value common stock; a warrant to purchase one share of common
stock of the Company at an exercise price of $2.00 which expires on April 30,
1998; and a redeemable preferred share in the Company's subsidiary, AIFE. The
preferred share is redeemable at the option of the Company at any time or from
time to time at the discretion of AIFE's Board of Directors at a price of $1.00
per share. An overwhelming majority of investors were residents of Canada. The
securities comprising the Units were issued with a Rule 144 restrictive legend.
Each purchaser of a Unit was informed and advised about certain matters
concerning the Company including its business and financial affairs. No general
form of advertising was used in connection with the placement of such
securities. No underwriters were used in connection with the issuance of these
securities and no commissions were paid to any person. The Company relied on the
exemptions from registration contained in Sections 4(2) and 3(b) of the
Securities Act of 1933 (the "1933 Act") and Regulation S and Regulation D
promulgated under the 1933 Act.

SOUTHWESTERN WATER EXPLORATION CO.
(A Development Stage Enterprise)
Notes to Consolidated financial Statements

Period ended September 30, 1997

(Unaudited)
(Expressed in U.S. Dollars)

--------------------------------------------------------------------------------


INCORPORATION AND BASIS OF PRESENTATION:

    The Company is incorporated under the laws of the State of Colorado and is
    planning to develop projects for the production of water reservoirs in the
    United States but has not commenced active business.

    These financial statements are presented using U.S. dollars as the
    functional and reporting currency and have been prepared in accordance with
    generally accepted accounting principles in the United States. They include
    the accounts of the Company and its wholly owned subsidiary.


1.  ORGANIZATION AND BUSINESS:

    These financial statements have been prepared on the basis of accounting
    principles applicable to a going concern, which assume that the Company will
    continue in operations for the foreseeable future and will be able to
    realize its assets and discharge its obligations in the normal course of
    operations.

    At September 30, 1997 the Company is in the development stage, has a working
    capital deficiency, and has no history of generating cash flow from its
    operations. The Company intends to develop and market potable water
    throughout the United States southwest. During the development stage of the
    Company it has acquired the rights to a proprietary computerized drill stem
    test database (the "Database") which it believes will provide surface
    drilling locations to access deep (below 2,000 ft) subsurface aquifers. The
    Database provides specific information including surface location, depth(s)
    of aquifers, temperature, production capability, and mineral properties from
    wells previously drilled for hydrocarbons and subsequently abandoned.

    The Company has identified a number of sites which it believes will provide
    potable water, including a significant water reservoir in Nevada, by
    utilizing the Database. In order to develop these sites the Company needs to
    acquire access rights and raise financing in order to commence drilling.
    Once developed , it is the intent of the Company to market the water from
    these sites, or in the event it is unsuccessful, to sell the water rights.

    During its development stage, the Company has funded the acquisition of the
    Database and its operating activities primarily by issuing equity and other
    financial instruments. The Company anticipates that funding of future
    activities will be provided by the completion of a private placement of
    common stock for a minimum of $1.5 million. There can be no assurances,
    however, that the Company will be successful in completing the private
    placement.

--------------------------------------------------------------------------------


1.  ORGANIZATION AND BUSINESS (CONTINUED):

    In the event the private placement is not completed, the Company may incur
    additional short or long term debt, or seek to sell additional shares of
    common stock or stock purchase warrants, as deemed necessary by the Company,
    to generate working capital. There can be no assurance of the Company's
    ability to continue as a going concern. The application of the going concern
    concept is dependent upon the Company receiving the continued support of its
    shareholders, its ability to raise new capital and its ability to achieve a
    commercial level of production and sales and profitable operations.



2. SIGNIFICANT ACCOUNTING POLICIES:

    (a) Property, plant and equipment

        Property, plant and equipment are stated at cost. Depreciation is
        provided using a rate of 20% on a declining balance.

    (b) Development costs:

        Costs incurred in the development of water projects are expensed in the
        period incurred.

    (c) Foreign currency translation:

        The functional currency of the company is the U.S. dollar. Monetary
        assets and liabilities expressed in other currencies are translated at
        the period end rate and the resulting translation adjustments are
        recognized in income. Operating statement items are translated at the
        exchange rate in effect at the transaction date.

    (d) Use of estimates:

        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 revenue and expenses
        during the period. Actual results could differ from these estimates.

    (e) Period from commencement of operations:

        April 1, 1992 is considered the commencement of the current development
        stage activities of the Company. Prior to this date, the subsidiary was
        involved in other unrelated activities. Accordingly, cumulative amounts
        from April 1, 1992 to September 30, 1997 have been reported in the
        statements of loss and deficit, cash flow and the share capital note.

3. RELATED PARTY TRANSACTIONS:

    AIFE, American Institute of Formation Evaluation Ltd. ("AIFE Canada"), a
    related company, provides updates to the Company's licensed proprietary data
    base. During the three months ended September 30, 1997 $53,400 (1996 -
    $53,400) was charged by AIFE Canada for the updates, which costs are
    included in development expenses of the Company. In addition, $3,000 (1996 -
    $3,000) of office expenses were allocated by AIFE Canada to the Company.
    These transactions are in the normal course of operations and are measured
    at the exchange amount, which is the amount of consideration established and
    agreed to by the related parties.

    From time to time amounts are also advanced by AIFE Canada to the Company as
    and when required for operating purposes. There is, however, no obligation
    for AIFE Canada to make future advances. During the six months ended
    September 30, 1997 a net amount of $65,369 was advanced (1996: $3,983).

    On September 1, 1993 the Company acquired an exclusive 20 year license to
    use data owned by AIFE Canada to explore for water in the Continental United
    States. The license was acquired for $1 plus a license fee of 10% of the
    annual net cash flow from operations of the Company, to a maximum aggregate
    license fee of $1.5 million over the license term.

    The amount due to related company (AIFE Canada) of $561,377 (March 1997:
    $496,008) is non-interest bearing with no fixed terms of repayment and is
    classed as long term as AIFE Canada has agreed not to demand repayment
    within the next year.


4. MINORITY INTEREST:

    The minority interest consists of preferred shares issued by the Company's
    operating subsidiary. The 852,000 preferred shares are redeemable at the
    discretion of the subsidiary at the issued value of $1 per share and
    dividends are payable at the discretion of the subsidiary.
