ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS.

        The following discussion and analysis should be read in conjunction with
the Company's financial statements and the notes thereto contained elsewhere in
this filing.

Overview

        Sustainable Development International, Inc., a Nevada corporation, is a
development stage company formed on May 27, 1998 to provide innovative
technologies, products and services to improve efficiency, quality and
environmental concerns in a variety of fields, with a particular emphasis on
solutions to environmental problems, reductions in energy consumption, health
and wellness and responsible resource development. The Company is divided into
five divisions: Energy, Sustainable Health, Funding, Natural Resources and
Alternative Energy.

        On November 22, 1999, the company announced that it has incorporated
Intercontinental Granite Incorporated. The company will own 80% of the
outstanding common shares of International Granite Incorporated for nominal
consideration.

        On December 16, 1999, the company entered into an agreement to form
Pro-Active Incorporated. The company will own 60% of Pro-Active Incorporated for
nominal consideration, which will manage health care information through the use
of integrated systems, customized databases and intelligent ID cards.

        On January 14, 2000, the company acquired 22,500 acres of mineral claims
under a metallic and industrial mineral permit.

        On March 21, 2000, the company entered into an agreement to form
Watergas Incorporated. The company will own 70% of Watergas Incorporated for
nominal consideration, which will be in the business of producing,
merchandising, marketing, distribution, promotion and selling of products
manufactured by The WGI Process (Hydrogen/Oxygen Generator).

Results of Operations for the three months ended April 30, 1999

      Total operating expenses from continuing operations were $63,498 for the
three months ended April 30, 2000, a 89 day period, as compared to the operating
expenses of $224,896 for the period of inception of the Company through its year
end of October 31, 1999, a period of 522 days. Utilizing an average daily
calculation of operating expenses of $713.46 for the period ending April 30,
2000, and an average daily calculation of operating expenses of $473.38 for the
annual period ending October 31, 1999, this represented a 50% increase in
average daily operating expenses.

      The increase in expenses was primarily the result of the Company
increasing its business activities in generating sales during the period ending
April 30, 2000.



                                                                          Page 9

Forward-Looking Statements and Associated Risks

     This Quarterly Report on Form 10-QSB contains forward-looking statements
made pursuant to the safe harbor provisions of the Securities Litigation Reform
Act of 1995. These forward looking statements are based largely on the Company's
expectations and are subject to a number of risks and uncertainties, many of
which are beyond the Company's control, including, but not limited to, economic,
competitive and other factors affecting the Company's operations, markets,
products and services, expansion strategies and other factors discussed
elsewhere in this report and the documents filed by the Company with the
Securities and Exchange Commission. Actual results could differ materially from
these forward- looking statements. In light of these risks and uncertainties,
there can be no assurance that the forward-looking information contained in this
report will in fact prove accurate. The Company does not undertake any
obligation to revise these forward-looking statements to reflect future events
or circumstances.

Liquidity and Capital Reserves

As of April 30, 2000 (Unaudited)

     As of April 30, 2000, the Company's assets were $1,757,390 and its
liabilities were $738,361, resulting in an excess of assets of $1,019,029. Cash
was $137,918 at April 30, 2000 as compared to cash of $155,042 on October 31,
1999, a decrease of $17,124. This represented a 12% decrease in available cash.
This decrease was primarily the result of an increase in operating expenses and
a cash deposit of $40,406 to Enviro-Mining for purposes of acquiring additional
oil related technologies.

     The Company has continued to fund its deficit cash flow from private
placements of the Company's common stock. It is anticipated that loans and the
sale of the Company's stock will continue until such time as the Company
generates sufficient revenues from its operations to cover operating expenses.



                                                                         Page 10
<PAGE>   11

Year 2000 Issues

     Certain of the Company's computer systems and software may interpret the
year 2000 as some other date. The operating system generally employed by the
Company is Windows 95, which is year 2000 compliant. The networking, general
ledger and accounts payable and facility point-of-sale and software programs
require software updates or modifications to address the year 2000 problem. The
Company is further addressing the matter by replacing certain older computers
and installing off-the-shelf and other third-party software that is year 2000
compliant, at an estimated cost of less than $1,000. The Company anticipates
that installation of year 2000 compliant software and hardware will be completed
by the end of 1999. The Company does not believe that the year 2000 problem will
have a material affect on the Company's operations, however, no assurance can be
given that the software updates and new computers will resolve the problem as
scheduled or at all.
