ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS

Our wholly owned subsidiary, FORTESA International, Inc. purchased a
controlling 75% interest in the ALGOA Field in Galveston County Texas on the
16th of August 2000 from RIATA ENERGY, Inc., a Texas corporation, as a result
of our arms-length negotiation with this non-affiliated party. We also
purchased new exploration acreage to the east of Algoa Field directly from
landowners on three (3) year leases to supplement the above mentioned
'held-by-production' acreage interests purchased from Riata. Combined, these
properties encompass up to 4,000 acres, and as a result of these transactions
we now operate Algoa's seven (7) producing oil and gas wells. In addition to
our share of these interests, approximately 15% of the working interest was
purchased by companies controlled by related parties, including our President
of Fortesa International, Inc. (5%), our Chairman (5%), and other
shareholders and investors through an investment partnership managed by our
Chairman (5%). These affiliates helped to finance this property acquisition
with us, and none of these affiliates are 'carried' by us on their working
interests.  Non-related parties hold the balance of the working interests in
this field.

The present costs of operating the Algoa Field exceed its current revenues by
approximately $15,000 per month.  Our plan is to seek financing to re-enter
and 'work-over' several of the existing wells to increase production, and to
recover additional reserves that we believe may be 'behind pipe' in such
wells. Following these intended workovers, we intend to cause a new 3D
seismic survey to be acquired over our field to delineate the Field and to
set locations for new drilling.  We intend to promote partners, shareholders,
or co-venturers to work with us to provide the funds for the above actions
and to drill new well(s) to develop new areas of the field that we believe
may have hydrocarbons remaining in-place.

We paid approximately $350,000 for the new acreage plus the controlling
interests of the former operator. We qualified to operate in Texas with the
Texas Railroad Commission.  We borrowed the funds to acquire our interest
this Field on short term financing from limited partners of the investment
partnership that will hold a 5% working interest in the Algoa Field.

ITEM 5. OTHER EVENTS

1) In the Republic of Senegal, we have commitments to install a gas pipeline
to place on-line our farm-in interests from the Petrosen discovery well for
delivery to the main power plant in Senegal.  Our Form 10-K for 1999
disclosed that we had a loan commitment letter from a large Senegalese Bank,
but that we were still negotiating to agree on terms for the project
financing that was approved to complete the pipeline installation.  In late
July 2000, we agreed on all terms with the Compangnie Bancaire de L'Afrique
Occidental, that is the 'CBAO Bank' in Dakar, and executed loan agreements
for $1,000,000 of project financing. We will not borrow any of these funds to
start the pipeline installation of our pipe that is in Senegal until we
receive the formal Ministerial Decree from the new government in Senegal
formally authorizing us to sell the gas.  We have formally applied for the
required decree and are awaiting approval by the Prime Minister of Senegal.

2) On August 29th 2000, the Company mailed its Annual Report for fiscal year
1999 on Form 10-K, with a cover letter from the Chairman.  A copy of the text
of this cover letter is as follows:-

TO OUR SHAREHOLDERS:

1999 WAS A SUCCESSFUL YEAR FOR OUR COMPANY AS WE WERE ABLE TO COMPLETE OUR
RESTRUCTURING.  THIS LONG AND DIFFICULT PROCESS RESULTED IN THE RETIREMENT OF
OUR LONG-TERM DEBT, OUR ACQUISITION OF AN INTEREST IN NATURAL GAS RESERVES IN
WEST AFRICA, AND OUR SUCCESSFUL DEVELOPMENT OF A NEW DIGITAL INFORMATION
PROCESS TO REVITALIZE OUR INFORMATION BUSINESS IN THE FUTURE.  THIS
RESTRUCTURING ENABLES US TO PROCEED WITH (I) OUR SEC FILINGS (II)
DISTRIBUTION OF OUR PROXY INFORMATION (III) AN ANNUAL MEETING OF
SHAREHOLDERS, AND (IV) COMPLIANCE WITH SEC REPORTING REQUIREMENTS.

THIS FINANCIAL RESTRUCTURING AND OUR MAJOR CHANGE IN BUSINESS PURPOSE AND
DIRECTION WERE COMPLETED THROUGH THE HARD WORK OF A SMALL NUMBER OF DEDICATED
AND KEY EMPLOYEES, CERTAIN OF OUR SHAREHOLDERS AND SECURED LENDERS THAT
ASSISTED IN OUR REFINANCING, THE OUTSIDE BOARD OF DIRECTORS THAT HAS
FAITHFULLY SERVED AND CONTRIBUTED INDEPENDENCE, LEADERSHIP ALTERNATIVES,
JUDGMENT, AND SERVICE, ALL WITHOUT CASH COMPENSATION, AND SEVERAL SIGNIFICANT
CUSTOMERS AND SUPPLIERS. WE SINCERELY THANK THESE PERSONS AND ENTITIES, AND
LOOK FORWARD TO THE CONTINUATION OF MUTUALLY SUCCESSFUL BUSINESS
RELATIONSHIPS WITH EACH.

OUR COMPANY HAS A DIFFERENT SET OF BUSINESS GOALS THAN IT DID IN 1992.  AT
THAT TIME, WITH THE DECREASING IMPORTANCE OF 2D SEISMIC DATA AND THE COLLAPSE
OF DOMESTIC NATURAL GAS PRICES, OUR CUSTOMERS RETREATED FROM U.S. DOMESTIC
EXPLORATION OPPORTUNITIES.  WE CEASED ALL OPERATIONS IN FIRST SEISMIC
CORPORATION IN DECEMBER 1993, AND REFOCUSED OUR EFFORTS ON (I) A BROAD RANGE
OF GEO-SCIENTIFIC STUDIES AND (II) THE INTERNATIONAL OIL AND GAS UPSTREAM
EXPLORATION BUSINESS.  THIS NEW BUSINESS FOCUS WAS EXECUTED THROUGH A WHOLLY
OWNED SUBSIDIARY, FIRST EXCHANGE CORPORATION, WITH FOCUSES INITIALLY IN SOUTH
AMERICA (1994-1995), THEN IN THE CASPIAN SEA REGION (1996-1997), AND FINALLY
IN WEST AFRICA (1998 TO PRESENT).  THIS SUCCESSFUL EFFORT PROVIDED THE
REVENUE STREAM TO FUND OPERATIONS AND RETIRE OBLIGATIONS LEFT FROM THE LOSS
OF FIRST SEISMIC'S FORMERLY SUCCESSFUL DOMESTIC U.S. 2D SEISMIC BUSINESS
PLAN.

OUR ANNUAL REPORT ON FORM 10-K FOR 1999 HAS BEEN RECENTLY FILED WITH THE SEC,
AND THIS AND THE ACCOMPANYING AUDITED 1999 FINANCIAL STATEMENTS AND FOOTNOTES
PROVIDE A DETAILED EXPLANATION OF OUR BUSINESS OPERATIONS, FINANCIAL
CONDITION, RESULTS OF OPERATIONS, AND THE CURRENT PROJECTS UPON WHICH WE HOPE
TO NOW REBUILD SHAREHOLDER VALUE.  ADDITIONAL INFORMATION REGARDING OUR
OPERATIONS IS INCLUDED IN THE ACCOMPANYING 10-K AND FINANCIALS THAT DISCUSSES
THE TWO SYNERGISTIC CAPABILITIES ON WHICH WE SEEK TO BUILD IN THE FUTURE: THE
DIGITAL INFORMATION BUSINESS AND THE HYDROCARBON EXPLOITATION BUSINESS.

--> DIGITAL INFORMATION - Our FIRST EXCHANGE product line is composed of a
    series of geo-scientific products that we own or manage and distribute for
    license fees to interested exploration companies.  Our capabilities also
    include promoting acreage and investment opportunities for our customers and
    partners.

    DETAILS OF OUR PRODUCTS CAN BE VIEWED AT WWW.FIRST-EXCHANGE.COM. IN
    ADDITION, WITH ONE INITIAL CUSTOMER AS A KEY USER, WE HAVE DEVELOPED A
    PROCESS WHEREBY WE CAN SCAN AND USE OCR (OPTICAL CHARACTER RECOGNITION) ON
    ANY EXPLORATION INDUSTRY IMAGE USED BY AN OIL COMPANY, AND DELIVER THAT IN
    DIGITAL FORM INTO A NORMAL PC ENVIRONMENT UNDER OPEN STANDARDS FOR USE
    WITHIN AN EDMS (ELECTRONIC DATA MANAGEMENT SYSTEM) OR PC NETWORK, OR FOR
    USE THROUGH THE INTERNET.  OUR PROCESS CAN ACCOMMODATE ANY SIZE DOCUMENT
    NORMALLY USED, IN BOTH COLOR AND BLACK AND WHITE IMAGES.  THESE IMAGES
    INCLUDE SEISMIC DATA, WELL LOGS, GEOLOGIC MAPS AND FIGURES, AS WELL AS TEXT
    DOCUMENTS.

    THIS PROCESS MAY HELP DISTRIBUTE OUR FIRST EXCHANGE BROKERED GEO-SCIENTIFIC
    MATERIALS THROUGH A PLAN TO CONVERT OUR INTERNET WEBSITE INTO AN E-COMMERCE
    DISTRIBUTION SYSTEM.  SUMMARY DETAILS OF OUR PROCESS CAN BE SEEN ON THE NEW
    WEBSITE OF OUR SUBSIDIARY AT WWW.ESMARTIMAGE.COM.  IT IS OUR GOAL FOR OUR
    ESMARTIMAGE PROCESS TO MAKE OUR INFORMATION LICENSING BUSINESS MORE
    COMPETITIVE BY DECREASING OUR COSTS OF DISTRIBUTION.

--> HYDROCARBON EXPLOITATION - OUR FORTESA INTERNATIONAL, INC. SUBSIDIARY HAS
    CONTRACTUAL RIGHTS TO AND OPERATING CONTROL OF A GAS DISCOVERY WELL IN AN
    ONSHORE EXPLORATION AREA IN THE REPUBLIC OF SENEGAL THROUGH A 'FARM-IN' WITH
    THAT COUNTRY'S NATIONAL OIL COMPANY.  WE ANTICIPATE RECEIVING THE NECESSARY
    DECREES FROM THE RECENTLY ELECTED GOVERNMENT IN SENEGAL TO PROCEED WITH THE
    INSTALLATION OF THE DELIVERY PIPELINE TO BRING NATURAL GAS TO BE PRODUCED
    FROM THIS AREA TO A READY MARKET IN SENEGAL FOR POWER GENERATION.  WE HAVE
    SPENT SEVERAL YEARS OF GEO-TECHNICAL PREPARATIONS FOR DRILLING AND
    PRODUCING, AND HAVE SECURED FINANCING NECESSARY TO START PRODUCTION FROM THE
    DISCOVERY WELL.  WE WILL NEED AN EXTENSION OF TIME TO COMPLETE THE FIRST
    PHASE OF OPERATIONS DUE TO DELAYS IN 1999 AND 2000 THAT WERE BEYOND OUR
    CONTROL, AND WE NEED TO RAISE ADDITIONAL FUNDS TO DRILL AT LEAST SEVERAL
    CONFIRMATION WELLS ONCE THE PIPELINE IS OPERATIONAL, WHICH COULD OCCUR LATE
    THIS YEAR.

    IN ADDITION, THIS SUMMER WE ACQUIRED LEASES TO, AND THE OPERATING
    RESPONSIBILITY FOR A PRODUCING OIL AND GAS FIELD OUTSIDE OF HOUSTON IN ALGOA
    TEXAS.  WE ACQUIRED CONTROLLING INTEREST IN 4,000 ACRES IN AND AROUND A
    KNOWN GEOLOGIC STRUCTURE, INCLUDING NEW ACREAGE THAT WE BELIEVE MIGHT HAVE
    DEEP DRILLING POTENTIAL.  NEXT, WE WILL SEEK FUNDS TO WORKOVER SEVERAL OF
    THE OLD WELLS TO INCREASE PRODUCTION, TO ACQUIRE A 3D SEISMIC SURVEY OVER
    THIS FIELD AND TO DRILL NEW IN-FILL WELLS.  THIS PROPERTY IS NOT
    COMMERCIALLY VIABLE AT ITS PRESENT LEVEL OF PRODUCTION, BUT WITH THE
    APPLICATION OF NEW INVESTMENT AND TECHNOLOGY, WE BELIEVE IT CAN BECOME AN
    EXCELLENT COMPLEMENT TO OUR RESERVES AND OPERATIONS IN SENEGAL.

WE INTEND TO CALL FOR AN ANNUAL MEETING OF SHAREHOLDERS DURING THE FOURTH
QUARTER OF 2000 TO DISCUSS OUR BUSINESS PLANS.  WE BELIEVE WE HAVE THE KEY
PERSONNEL AND THE EXPERTISE WITHIN THE COMPANY TO REBUILD A SOLID BASE OF
OPERATIONS, RECOVER FROM THE LOSS OF OUR 2D SEISMIC BUSINESS AT THE END OF
1991, AND OVERCOME OUR LOSSES IN 1998 AND 1999 CAUSED BY THE PRECIPITOUS
DECLINE IN OIL AND GAS PRICES.  THOUGH WORLDWIDE OIL AND GAS EXPLORATION HAS
NOT YET RETURNED TO LEVELS THAT EXISTED BEFORE 1998, WE EXPECT OUR BUSINESS
TO REBOUND AND GROW.

FORM 8-K                                                                Page 4

OUR FUTURE SUCCESS DEPENDS UPON (1) OUR EXPERTISE AND ABILITY TO APPLY
GEO-SCIENTIFIC TECHNOLOGY IN A COST-EFFECTIVE MANNER TO ASSIST EITHER OUR
CUSTOMERS OR OURSELVES IN DEVELOPING OWNERSHIP INTERESTS IN HYDROCARBON
PRODUCING ASSETS, AND (2) OBTAINING AN ADEQUATE FINANCING TO EFFECT OUR PLANS
TO DEVELOP HYDROCARBON RESERVES, AND TO BRING OUR SPECIAL EXPERTISE IN THE
DISTRIBUTION OF INFORMATION IN DIGITAL FORM TO THE MARKETPLACE.

THANK YOU FOR YOUR PATIENCE OVER THE PAST SEVERAL YEARS AS WE HAVE WORKED TO
INTERNALLY RESTRUCTURE THE COMPANY AND TO REGAIN AN ADEQUATE CAPITAL BASE.
WE HAVE SUCCEEDED IN TRANSITIONING OUR COMPANY TO A NEW BUSINESS PURPOSE IN
AN EVER CHANGING AND DYNAMIC BUSINESS CLIMATE; A CLIMATE THAT HAS BECOME
INCREASINGLY TECHNOLOGICAL AND COMMUNICATIONS ORIENTED.  WE ARE PROUD OF WHAT
WE HAVE ACHIEVED AND BELIEVE THE POTENTIAL EXISTS FOR SIGNIFICANT GROWTH IF
WE ARE SUCCESSFUL IN RAISING THE CAPITAL NECESSARY TO IMPLEMENT OUR CONTRACTS
AND APPLY OUR TECHNOLOGIES IN THE IMMEDIATE FUTURE.
