ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION.

General

        Southwestern Water Exploration Co. (the "Company"), 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.

(c)  Recent Sales of Unregistered Securities

        From March to June 1998, the Company offered its stockholder the
opportunity to convert shares of Preferred Stock of AIFE into shares of Common
Stock of the Company and to convert their warrants of the Company into shares of
Common Stock of the Company. Shares of Preferred Stock of AIFE were converted
into shares of Common Stock of the Company on a one for one basis. Warrants of
the Company were converted into shares of Common Stock of the Company on a 1:.76
basis. No general form of advertising was used in connection with the exchange
of such securities. No underwriters were used in connection with the exchange of
these securities and no commissions were paid to any person. The Company relied
on the exemptions from registration contained in Sections 3(a)(9) of the
Securities Act of 1933 (the "1933 Act") and Regulation D promulgated under the
1933 Act. As a result of the conversion and exchange, 1,744,160 shares of Common
Stock of the Company were issued to existing stockholders.

        From September 30, 1995 to September 30, 1998, the Company issued
approximately 582,000 Units to certain sophisticated individuals at a price per
Unit of $1.00 for a total offering of $582,000. 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 expired 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 1933 Act
and Regulation S and Regulation D promulgated under the 1933 Act.
