                               PROSPECTUS SUMMARY
   
  The following is a summary of certain significant matters discussed elsewhere
in this document. This Summary is qualified in its entirety by reference to the
more detailed information appearing elsewhere in this Prospectus including
information under "Risk Factors." Prospective investors are urged to read the
entire Prospectus. Certain terms used in this Summary and elsewhere in this
Prospectus are used as defined in the Summary or elsewhere in this Prospectus.
See the "Glossary of Certain Industry Terms" appearing at the end of this
Prospectus for the definitions of certain terms used herein. Unless otherwise
indicated, all information contained in this Prospectus assumes that the
Underwriters' over-allotment option as described in "Underwriting" is not
exercised. The "Company" means Zydeco Energy Inc. and its wholly-owned
subsidiaries, Zydeco Exploration Inc. and Wavefield Image, Inc., and, unless
the context otherwise requires, such subsidiaries are also included in the
description of the Company. The Shares offered hereby involve a high degree of
risk and investors should carefully consider information set forth in "Risk
Factors."     
 
                                  THE COMPANY
   
  Zydeco Energy, Inc. ("Zydeco" or the "Company") is an independent energy
company engaged in the exploration for oil and gas in areas utilizing advanced
3D seismic and computer aided exploration ("CAEX") techniques. The Company
believes it is one of the few independent exploration companies with
comprehensive in-house technology and expertise enabling it to use the most
recent advances in such 3D seismic and CAEX technology. Zydeco's geophysicists
design the seismic data acquisition survey, manage the acquisition of seismic
data and process and interpret the resulting data. The Company believes that
its technology and expertise enable it to acquire and analyze seismic data
efficiently over large geographical areas. The Company attempts to concentrate
its efforts in areas previously unexplored with advanced 3D seismic technology.
Based upon analysis of processed data, Zydeco personnel identify and rank
potential oil and gas prospects for leasehold acquisition. The Company intends
to enter into agreements with experienced industry partners for the development
of such prospects and retain significant non-operating production interests in
those prospects.     
   
  Zydeco's present exploration efforts are focused in the Louisiana Transition
Zone, the region of land and shallow water extending several miles both onshore
and offshore from the coastline of Louisiana. The Louisiana Transition Zone is
part of a geologically complex trend in which large oil and natural gas
reserves have been discovered and produced. However, the Company believes that
the Louisiana Transition Zone has historically been underexplored with 3D
seismic techniques relative to nearby and geologically related deeper waters
and lands inland from the coastline, primarily due to characteristics that make
seismic data acquisition difficult and expensive. The Company believes that the
comparatively low levels of 3D seismic exploration in the Louisiana Transition
Zone provide significant opportunities for prospect identification in a region
with prolific historical oil and gas production.     
   
  The Company's three senior executives have an average of 29 years experience
in the oil and gas exploration business. In addition, the Company has assembled
an experienced exploration team of geophysicists and geologists with
substantial industry experience in exploration and advanced seismic technology
and analysis. This team has successfully assembled an integrated hardware and
software seismic processing system which allows the Company to capitalize on
the most recent developments in 3D seismic and CAEX technology. These recent
developments include a processing technique initially licensed and recently
acquired by the Company ("Wavefield Imaging Technology") which substantially
reduces the cost of seismic data acquisition for certain surveys while
improving the resolution of the subsurface image. The Company recently acquired
Wavefield Image, Inc. ("Wavefield"), the owner and licensor of the Wavefield
Imaging Technology. On July 3, 1997, the Company received notice that a patent
application in respect of Wavefield Imaging Technology has been allowed for
patent issuance by the United States Patent and Trademark Office. The Company
expects that the patent will be issued in a few months.     
   
  The Company's primary objective is to discover and develop oil and gas
reserves and increase cash flow through exploration, prospect identification
and participation in projects to develop such prospects. Key elements of the
Company's strategy include: (i) focusing its efforts in geologic areas that it
believes are seismically underexplored and have the potential for substantial
oil and gas reserves; (ii) continuing to develop and apply its advanced in-
house     
 
                                       4
<PAGE>
 
   
3D seismic technology and expertise; and (iii) pursuing joint ventures with
industry partners to drill and develop producing properties from such
prospects. To date, the Company has not generated net income primarily because
of the significance and timing of its exploration expenditures and the
substantial investments in advanced supercomputing processors and software
required to keep pace with the most recent advances in CAEX technologies.     
   
  In August 1996, the Company commenced an extensive 3D seismic exploration
program in a part of the Louisiana Transition Zone in western Cameron Parish,
Louisiana (the "West Cameron Seismic Project") utilizing the Wavefield Imaging
Technology. As of July 1, 1997, the Company had acquired seismic permits and
exclusive seismic options on approximately 151,000 contiguous acres onshore and
in state and federal waters, including 51,000 acres with respect to which the
Company has an exclusive seismic permit and 36,000 acres with respect to which
the Company has lease options. As of July 1, 1997, seismic data acquisition has
been completed over approximately 90% of the West Cameron Seismic Project
acreage. The Company presently expects to complete data acquisition in the
summer of 1997 and commence lease acquisition for identified prospects in late
1997. While the Company believes the preliminary analysis of the data acquired
from the West Cameron Seismic Project is promising for prospect identification,
no assurances can be made as to the results of further processing and analysis
of such data or as to the existence of recoverable hydrocarbons on the West
Cameron Seismic Project acreage. No assurances can be made as to the existence
of recoverable hydrocarbons on the West Cameron Seismic Project acreage or in
any other areas in which the Company explores.     
   
  The Company is financing the West Cameron Seismic Project in part through an
exploration agreement (the "Cheniere Exploration Agreement") with Cheniere
Energy Operating Co., Inc. ("Cheniere"). Pursuant to the Cheniere Exploration
Agreement, Cheniere agreed to pay for all of the costs of permits, options and
seismic data acquisition and processing for the West Cameron Seismic Project up
to a maximum of $13.5 million, plus 50% of such costs in excess of $13.5
million, in exchange for an interest of up to 50% in the West Cameron Seismic
Project. As of July 1, 1997, Cheniere had paid $12.0 million. Under the terms
of the Cheniere Exploration Agreement, Cheniere may elect to cease payment of
costs at any time, in which case its interest in the West Cameron Seismic
Project would be proportionately reduced.     
   
  In addition to its interests in the West Cameron Seismic Project, the Company
has identified a number of other potential prospects in the Louisiana
Transition Zone, most of which were identified prior to conducting any 3D
seismic surveys. As of March 31, 1997, the Company held oil and gas leases
covering approximately 21,480 gross acres (11,326 net acres) in Louisiana State
and Federal waters. Approximately two-thirds of these potential prospects are
owned equally by Fortune Petroleum Corp. ("Fortune") pursuant to an agreement
(the "Fortune Exploration Agreement") between the Company and Fortune. In June
1997, Fortune exercised its right under the Fortune Exploration Agreement to
have returned to it $2.2 million in unexpended funds which it had previously
advanced to the Company to cover anticipated lease acquisition and exploration
expenses relating to the co-owned prospects. Although the Company plans to
pursue further evaluation of certain of these potential prospects, including
the possible sale of some of these prospects, there can be no assurance that
any of the potential prospects will be drilled or will contain any commercially
recoverable amounts of oil and gas.     
 
  The Company's principal offices are located at Two Allen Center, 1200 Smith
Street, Suite 1710, Houston Texas 77002. Its telephone number is (713) 659-
2222.

                                 RISK FACTORS
 
  Statements contained in this Prospectus concerning expected results or
estimates of future capital expenditures, production volumes, reserve volumes,
reserve values, number of development and exploration projects, total assets,
cash flow and earnings are forward-looking statements. When used in this
Prospectus the words "expect," "estimate," "project" and similar expressions
are also intended to identify forward-looking statements. All such statements
are based on assumptions concerning, among other things, the timing and
completion of projects, commodity prices, recompletion and drilling results,
lease operating expenses, administrative expenses, interest, and other
financing costs that management believes are reasonable based on currently
available information. The Company's assumptions and the Company's actual
future performance, however, are both subject to a wide range of business
risks and there is no assurance that these goals and projections can or will
be met. The securities offered hereby involve a high degree of risk. Each
prospective investor should carefully consider, among other factors, the
following risks inherent in, and affecting the business of the Company and the
securities offered hereby before making an investment decision. Some of these
risks are described in summary form below. Investors should read the section
or sections of this Prospectus cross-referenced below for a more complete
discussion of certain of these risks.
 
LIMITED OPERATING HISTORY AND SIGNIFICANT HISTORICAL OPERATING LOSSES
 
  The Company has a limited operating history. Potential investors, therefore,
have limited historical financial and operating information upon which to base
an evaluation of the Company's performance and an investment in the Shares.
The Company's potential must be considered in light of the risks, expenses and
difficulties frequently experienced by companies in the early stages of their
development. As a result of operating expenses, the Company has incurred
significant operating and net losses to date. Net losses for the period from
inception on March 17, 1994 through December 31, 1994, and for the years ended
December 31, 1995 and 1996 were approximately $0.1 million, $1.2 million and
$1.9 million respectively. Net loss for the three month period ended March 31,
1997 was approximately $0.6 million. At March 31, 1997, the Company had
accumulated a deficit of $3.7 million. The Company's future financial results
will depend primarily on its ability to locate hydrocarbons economically in
commercial quantities, to identify drillable prospects that result in
profitable productive wells and on the market prices for oil and gas. There
can be no assurance that the Company will achieve or sustain profitability or
positive cash flows from operating activities in the future. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
   
NEED FOR ADDITIONAL FINANCING     
   
  Most of the Company's operations are in the early stages of oil and gas
exploration. The Company's operations have not generated and, in the near
future, are not expected to generate, cash flows sufficient to fund operations
and exploration expenditures. Accordingly, the Company expects that it will
need substantial additional capital in order to sustain operations, to fund
anticipated expenditures for the acquisition of additional oil and gas leases
and to drill wells on the Company's prospects, if any. The Company incurred
capital expenditures of $11.2 million (including exploration costs of
approximately $1.8 million) in the six months ended June 30, 1997 and plans to
incur capital expenditures of approximately $4.5 million (including
exploration costs of approximately $2.7 million) in the remaining two quarters
of 1997. Management believes that the Company will have sufficient cash,
including the net proceeds of the offering made by this Prospectus (the
"Offering"), to fund planned expenditures to January 1, 1999. Additional
capital may be secured from a combination of funding sources that may include
borrowings from financial institutions, joint venture partnerships, vendor
financings, production payment financings, debt offerings, or additional
offerings of the Company's stock. The timing and extent of the need for
additional financing will depend, in part, on whether Cheniere elects to
continue to provide funds pursuant to the Cheniere Exploration Agreement. The
Company's ability to access additional capital will depend on its success in
acquiring and developing oil and gas exploration prospects with commercial oil
and gas reserve potential and on the productivity of the oil and gas leases
which the Company owns, or controls or acquires in the future. The Company's
ability to meet its needs for additional financing will also depend on the
    
                                       8
<PAGE>
 
status of various capital markets and industry conditions at the time such
additional capital is sought. There is no assurance that capital will be
available to the Company from any source or that, if available, it will be on
terms acceptable to the Company. There can be no assurance that the Company
will be able to generate or raise sufficient capital to enable it to realize
fully all of its strategic objectives. Should sufficient financing not be
available because costs are higher than estimated, a partner on a project
fails to meet its financing obligations or otherwise, the development and
exploration of any prospect developed by the Company would be delayed or
possibly lost and, accordingly, the implementation of the Company's business
strategy could be adversely affected. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations" and "Business and
Properties--Strategy."
 
OIL AND GAS INDUSTRY CONDITIONS AND PRICE VOLATILITY
 
  As an independent energy company, the Company's revenues and profits will be
substantially dependent on the oil and gas industry in general and the
prevailing prices for oil and gas in particular. Historically, the markets for
oil and gas have been volatile and are likely to continue to be volatile in
the future. Prices for oil and gas are subject to wide fluctuations in
response to small changes in supply of and demand for oil and gas, market
uncertainty and a variety of additional factors that are beyond the control of
the Company. These factors include political conditions in the Middle East,
the domestic and foreign supply of oil and gas, the price of foreign imports,
the level of consumer demand, weather conditions, domestic and foreign
government regulations, the price and availability of alternative fuels and
overall economic conditions. It is impossible to predict future oil and gas
price movements with any certainty. Declines in oil and gas prices would
adversely affect the Company's cash flow, liquidity and profitability, and
will reduce the amount of the Company's oil and gas reserves that can be
economically produced or make some potential prospects uneconomical to
develop. In addition, various factors, including the availability and capacity
of gas gathering systems and pipelines, the effect of federal regulations on
production and transportation, general economic conditions and changes in
supply and demand, may materially adversely affect the Company's ability to
market its oil and gas production. See "Business and Properties--Competition
and Markets" and "--Governmental Regulation."
 
RELIANCE ON TECHNOLOGY
   
  The Company uses its recently developed Wavefield Imaging Technology to
gather and analyze the seismic data it acquires. The Company has recently
acquired Wavefield, the owner of the Wavefield Imaging Technology. The
Wavefield Imaging Technology has not yet been used to identify a prospect
which was then drilled and shown to have proved reserves. On July 3, 1997, the
Company received notice that a patent application in respect of the Wavefield
Imaging Technology has been allowed for patent issuance by the United States
Patent and Trademark Office. The Company expects that the patent will be
issued in a few months. Prior to the acquisition, Wavefield granted licenses
for the Wavefield Imaging Technology to one major oil company and one foreign
company and offered a license to another foreign company.     
 
  A number of other companies are engaged in the research and development of
seismic acquisition and analysis technology. In the future, such companies may
develop more advanced seismic imaging and analysis technology which could be
made available to the Company's competitors, but may not be made available to
the Company. If the Company is unable to utilize the most advanced
commercially available technology, the Company's business, financial condition
and results of operations could be materially and adversely affected. See
"Business and Properties--Technology."
 
DEPENDENCE UPON SUCCESSFUL IDENTIFICATION OF PROSPECTS
 
  The Company will, for the near future, dedicate substantial capital
resources to identifying and developing potential prospects on existing or
future acquired leases utilizing its enhanced 3D seismic technology. A
significant investment will be required to obtain, process and interpret the
additional geophysical and geological data necessary to complete this
analysis, particularly with respect to the West Cameron Seismic Project. There
 
                                       9
<PAGE>
 
can be no assurance that after such expenditures the Company will identify any
prospects suitable for drilling on its current leases or on future acquired
leases. Because of the inherent uncertainties in developing specific
exploratory prospects pursuant to this analysis, there is also no assurance as
to the timing or amount of drilling operations that the Company may undertake.
The inability to identify sufficient prospects suitable for drilling will have
a material adverse effect on the Company's business, financial position and
results of operations. See "Business and Properties."
 
DEPENDENCE UPON SUCCESSFUL LEASE ACQUISITION ACTIVITIES
 
  If the Company identifies areas with significant potential for oil and gas
reserves, the success of the Company's business plan will be dependent upon
the successful acquisition of leasehold or other drilling rights in the
identified properties. Governmental entities generally award oil and gas
leases on a competitive bidding basis. For example, while the Company has
retained the exclusive right to nominate for bid any acreage covered by its
state waters seismic permit relating to the West Cameron Seismic Project until
February 1998, the bidding for such acreage will be competitive. The
acquisition of onshore oil and gas leaseholds and related seismic rights is
often extremely competitive. The Company expects that other major and
independent oil and gas companies having financial resources significantly
greater than those of the Company will compete with the Company for the
acquisition of oil and gas leases in areas targeted by the Company.
Accordingly, there can be no assurance that the Company will be successful in
acquiring any leases on which it bids even after incurring significant
expenditures. See "Business and Properties."
 
EXPLORATION AND OPERATING RISKS OF OIL AND GAS OPERATIONS
 
  The Company's oil and gas operations are subject to all of the risks and
hazards typically associated with the exploration for, and the development and
production of, oil and gas in the Louisiana Transition Zone and any other
areas in which the Company may conduct such activities. Risks in exploratory
drilling include the risk that no commercially productive oil and gas
reservoirs will be encountered. Risks in exploration also include liability to
landowners for damage caused by seismic charges and delays due to weather and
sea conditions. The cost of drilling, completing and operating wells is often
uncertain and drilling operations may be curtailed, delayed or canceled as a
result of a variety of factors including unexpected formation and drilling
conditions, pressure or other irregularities in formations, equipment failures
or accidents and delays in the delivery of equipment. Risks in drilling
operations also include blowouts, oil spills, fires and offshore risks such as
capsizing, collision, hurricanes and other adverse weather and sea conditions.
Such risks can result in personal injury, loss of life, substantial damage to
or destruction of oil and gas wells, platforms, production facilities or other
property, suspension of operations and liabilities to third parties, any or
all of which could adversely affect the Company.
 
  The Company's operations could also result in liability for oil spills,
discharge of hazardous materials, other environmental damages and other
property damage. In accordance with customary industry practices, the Company
intends to maintain insurance against some, but not all, of such risks and
some, but not all, of such losses. There can be no assurance, however, that
any insurance coverage the Company intends to carry will be available to the
Company when applied for or, if available and carried, will be adequate to
cover the Company's liability in all circumstances. See "Business and
Properties--Operational Risks and Insurance." The occurrence of an event not
fully covered by insurance could have a material and adverse effect on the
financial position and results of operations of the Company. In addition, the
Company may be liable for environmental damages caused by previous owners of
any property which may be purchased by the Company, which liabilities would
not be covered by insurance. See "Business and Properties--Governmental
Regulation."
 
  Most of the oil and gas leases the Company has acquired or currently expects
to acquire are or will be located offshore in water depths of less than 130
feet. Drilling operations offshore in such water depths are by their nature
more remote, exposed and, consequently, more susceptible to the risks
described above.
 
COMPETITION
 
  The exploration for and production of oil and gas are highly competitive.
Many companies and individuals are engaged in the business of exploring for,
acquiring interests in and developing onshore and near onshore oil and gas
properties in the United States. The Company competes with major and
independent oil and gas
 
                                      10
<PAGE>
 
companies for the acquisition of oil and gas leases and producing properties
as well as for the capital, equipment and experienced labor required to
locate, develop and operate such properties. Many of these competitors have
financial, technical, human and other resources substantially greater than
those of the Company. Such competitive disadvantages could affect the
Company's ability to successfully identify, obtain rights to, and develop
prospects. See "Business and Properties--Competition and Markets"
 
FLUCTUATIONS IN QUARTERLY OPERATING RESULTS
 
  The Company may experience significant fluctuations in its quarterly
operating results. The Company's future operating results are dependent upon a
number of factors, including, but not limited to, the success of the
exploration and drilling activities of the Company and its industry partners,
the timing of the expenses incurred for such activities, the demand for oil
and gas and economic conditions, both generally and in the oil and gas
industry. In particular, a dry hole or failure to obtain a lease for a
prospect on which the Company has incurred substantial exploration costs could
have an almost immediate impact on the Company's business, financial condition
and results of operations. See "Management's Discussion and Analysis of
Financial Condition and Results of Operation."

  Certain of the Company's officers, directors, employees and stockholders own
working and overriding royalty interests in leases owned by the Company or
that adjoin, or are in the vicinity of, some of the potential prospects
described herein. Such officers, directors, employees and stockholders will
continue to conduct operations on such leases, including, without limitation,
acquiring or shooting, processing and/or reprocessing seismic data,
remediating or recompleting existing wells and/or the drilling of new wells.
Hence, a conflict of interest may exist if the Company proposes to drill or
farmout for the drilling of a well or wells upon leases it currently owns and
leases immediately offsetting the leases owned by its officers, directors,
employees or stockholders.
 
  Certain members of the Company's management team are also investors,
executive officers and/or directors of other small privately owned independent
oil companies with limited operations. Though these members of the Company's
management team intend to spend the substantial majority of their business
time managing the affairs of the Company, there may be a conflict of interest
in the apportionment of management time between the business matters of the
Company and any other positions they hold. Company transactions with related
parties have been and will be subject to the approval of the independent
directors. See "Management--Conflicts of Interest."
 
DEPENDENCE ON MANAGEMENT AND KEY PERSONNEL
   
  The Company believes that its success will be highly dependent upon its
continued ability to attract and retain skilled senior management and key
personnel, including Sam B. Myers, Jr., Chairman and Chief Executive Officer,
Edward R. Prince, Jr., Vice Chairman, John O. Smith, President and Chief
Operating Officer and Norman S. Neidell, Vice President--Innovation, and
skilled exploration personnel. Furthermore, due to the recent increase in
exploration activity in the Gulf Coast, it is becoming increasingly more
difficult to attract and retain experienced and skilled exploration personnel.
Although the Company's employees intend to devote substantially all of their
time to the Company, they may devote a minor portion of their business time to
other business ventures. In the event that the Company loses the services of
any of its key personnel, there could be a material adverse effect on the
Company's business and prospects. The Company has not entered into employment
agreements with any of the foregoing individuals (other than Dr. Neidell), or
obtained key-man insurance on any officers or employees of the Company. The
Company does have employment agreements with three of its other employees. See
"Management."     
 
COMPLIANCE WITH GOVERNMENTAL REGULATIONS
 
  The Company's business is regulated by certain federal, state and local laws
and regulations relating to the development, production, marketing and
transportation of oil, gas and related products as well as certain
environmental and safety matters. These laws may be changed from time to time
in response to economic or
 
                                      11
<PAGE>
 
political conditions. Matters subject to regulation include permits for
drilling operations, drilling and abandonment bonds, reports concerning
operations, the spacing of wells, unitization and forced pooling of properties
and taxation. From time to time, regulatory agencies have imposed price
controls and limitations on production by restricting the rate of flow of oil
and gas wells below actual production capacity in order to conserve supplies
of oil and gas. In addition, the production, handling, storage, transportation
and disposal of oil and gas, by-products therefrom and other substances and
materials produced or used in connection with oil and gas operations are
subject to regulation under federal, state and local laws and regulations
primarily relating to the protection of human health and the environment.
These laws and regulations have imposed increasingly strict requirements for
water and air pollution control and solid waste management. The Company
believes the trend of more expansive and stricter environmental legislation
and regulations will continue and such legislation may result in increasing
costs to the Company in the future. Amendments to laws regulating the disposal
of oil and gas exploration and production wastes have been considered by
Congress and may be adopted. Moreover, new and additional taxes have been
proposed on energy consumption in the form of a BTU tax or a gasoline tax. Any
new legislation or taxes, if enacted, could have a significant adverse impact
on the Company's operating costs. See "Business and Properties--Governmental
Regulation."
 
UNCERTAINTY OF ESTIMATES OF OIL AND GAS RESERVES
 
  There are numerous uncertainties inherent in estimating oil and gas reserves
and in projecting future rates of production. Petroleum engineering is a
subjective process of estimating underground accumulations of oil and gas that
cannot be measured in an exact manner. Estimates of economically recoverable
oil and gas reserves and of future net cash flows depend upon a number of
variable factors and assumptions, such as historical production from the area
compared with production from other producing areas, the assumed effects of
regulations by governmental agencies, and assumptions concerning future oil
and gas prices, future operating costs, severance and excise taxes,
development costs, and workover and remedial costs, all which may vary
considerably from actual results. For these reasons, estimates of the
economically recoverable quantities of oil and gas attributable to any
particular group of properties, classifications of such reserves based on risk
of recovery and estimates of the future net cash flows, expected therefrom
prepared by different engineers or by the same engineers at different times
may vary substantially. Actual production, revenues and expenditures with
respect to the Company's reserves will likely vary from estimates, and such
variances may be material. See "Business and Properties--Oil and Gas
Reserves."
 
SHARES ELIGIBLE FOR FUTURE SALES; POTENTIAL ADVERSE EFFECT ON MARKET PRICE AND
DILUTION FROM EXERCISE OF WARRANTS AND OPTIONS
   
  The Company's Certificate of Incorporation authorizes the issuance of
50,000,000 shares of Common Stock, of which 8,707,098 shares would be
outstanding as of the date of this Prospectus after giving effect to
completion of the Offering. In addition, as of the date of this Prospectus,
the Company had outstanding (i) unit options and warrants to acquire 4,005,668
shares of Common Stock exercisable at an average price of $5.50 per share;
(ii) options to acquire 993,131 shares of Common Stock at an average price of
$1.60 per share, granted by Zydeco Exploration to its employees and assumed by
the Company; and (iii) 995,000 shares eligible for issuance pursuant to the
Company's 1996 Incentive Equity Plan and the Company's 1996 Non-employee
Directors Stock Option Plan, of which options for the purchase of 887,000
shares have been granted and currently remain outstanding as of the date of
this Prospectus and are exercisable at an average price of $5.92 per share.
See "Description of the Company's Securities." Most of the shares issuable
upon the exercise of outstanding options and warrants will become immediately
available for resale in the public market. In addition, the Company expects to
issue 150,000 additional shares to the shareholders of Wavefield pursurant to
the issuance of a patent of the Wavefield Imaging Technology. See "Business
and Properties--Technology." The Company and its officers, directors and
certain stockholders have agreed to not offer, sell, grant any option (except
pursuant to stock option plans) to purchase or otherwise dispose of a total of
4,436,470 shares held by such parties during the 180 days following the sale
of the shares being offered hereby without the prior consent of Brean Murray &
Co., Inc. See "Underwriting" and "Principal Stockholders." Sales of
substantial numbers of such shares in the public market could adversely affect
the market price of the Common Stock.     
 
                                      12
<PAGE>
 
STOCK PRICE VOLATILITY; LIMITED MARKET FOR THE COMPANY'S COMMON STOCK
 
  Factors such as announcements of technological innovations by the Company or
its competitors, as well as market conditions generally or in the oil and gas
industry, or changes in earnings estimates by securities analysts may cause
the market price of the Common Stock to fluctuate significantly. In addition,
the stock market in recent years has experienced significant price and volume
fluctuations which have particularly affected the market prices of equity
securities of many high technology and oil and gas exploration companies and
which often have been unrelated to the operating performance of such
companies. These market fluctuations may adversely affect the price of the
Common Stock. See "Price Range of Common Stock and Dividend Policy." In
addition, although the Common Stock is listed on the Nasdaq SmallCap Market,
the public market for the Common Stock has been relatively small. Stocks with
small markets and limited liquidity may experience fluctuations in their
prices due to imbalances between orders to buy and orders to sell the stock.
There can be no assurance as to when an active public market for the Common
Stock will develop, if at all. If, during the time in which the Common Stock
is quoted on the Nasdaq SmallCap Market, the Common Stock in any transaction
is priced below $5.00 per share, trading of the Common Stock may become
subject to federal regulations governing "penny stocks" (the "Penny Stock
Rules"). Application of the Penny Stock Rules may make it more difficult for
brokers to sell the Common Stock, and purchasers of the Common Stock offered
hereby may have difficulty in selling their shares in the future in the
secondary trading market.
 
POTENTIAL ADVERSE IMPACT OF ANTI-TAKEOVER PROVISIONS
 
  The Company's Certificate of Incorporation and Bylaws and the provisions of
Delaware General Corporation Law contain provisions which may be deemed to
have the effect of discouraging a third party from pursuing a non-negotiated
takeover of the Company because they have the effect of delaying, deterring or
preventing a change in control of the Company. The Company's Certificate of
Incorporation authorizes the issuance of "blank check" preferred stock with
such rights and preferences as may be determined from time to time by the
Board of Directors without stockholder approval. In the event of issuance, the
preferred stock could be used, under certain circumstances, to discourage,
delay or prevent a change in control of the Company even though such an
attempt might be economically beneficial to the stockholders of the Company.
Such provisions may have an adverse impact on the price of the securities of
the Company that are traded in the public market. See "Description of
Company's Securities."

                                USE OF PROCEEDS
   
  The net proceeds to the Company from the sale of the 2,000,000 Shares
offered hereby are estimated to be approximately $9,634,600, ($11,143,990 if
the Underwriters' over-allotment option is exercised in full) based on an
assumed public offering price of $5.41 per share, after deducting underwriting
discounts and commissions and estimated offering expenses payable by the
Company.     
 
  The Company currently intends to use such net proceeds to finance leasehold
acquisition costs, seismic data acquisition costs, processing and analysis
costs primarily in connection with the West Cameron Seismic Project, and, to a
lesser extent, for general corporate purposes, including working capital. The
Company may use a portion of the net proceeds from the Offering to participate
in the drilling of oil and gas wells if an opportunity to do so arises.
Pending such uses, the Company intends to invest the net proceeds in short-
term, interest bearing, investment grade securities.
 
  The Company expects to require funds, in addition to the proceeds from this
Offering, to complete all of the leasehold acquisitions for the West Cameron
Seismic Project. There can be no assurance that the Company will be able to
generate or raise sufficient capital to enable it to realize fully all of its
strategic objectives. The timing of the need for additional funds will depend,
in part, on whether or not Cheniere continues to provide funds for the West
Cameron Seismic Project. See "Risk Factors--Need for Additional Financing" and
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Liquidity and Capital Resources."

  As of July 1, 1997, the last reported sales price for the Company's Common
Stock on the Nasdaq SmallCap Market was $5.41 per share. At July 1, 1997, the
Company had approximately 56 stockholders of record. The Company believes that
certain holders of record hold a substantial number of shares of Common Stock
as nominees for a significant number of beneficial owners.     
 
  The Company has not paid any dividends on its shares of Common Stock to date
and the payment of future dividends is in the discretion of the Board of
Directors. It is the present intention of the Board of Directors to retain all
earnings, if any, for use in the Company's business operations and,
accordingly, the Board does not anticipate declaring any dividends in the
foreseeable future.

(1) As of March 31, 1997, the Company had outstanding (i) options to acquire
    150,000 units, exercisable at $6.60 per unit, composed of one share of
    Common Stock and two warrants to purchase one share of Common Stock each
    for $5.50; (ii) warrants to acquire 3,558,129 shares of Common Stock
    exercisable at an average price of $5.45 per share; (iii) options to
    acquire 1,004,693 shares of Common Stock at an average price of $1.60 per
    share, granted by Zydeco Exploration to its employees and assumed by the
    Company; and (iv) 995,000 shares of Common Stock eligible for issuance
    pursuant to the Company's 1996 Incentive Equity Plan and the Company's
    1996 Non-employee Director Stock Option Plan, of which options for the
    purchase of 615,000 shares of Common Stock were outstanding with a
    weighted average exercise price of $6.06 per share. Since March 31, 1997,
    the Company has (i) issued 13,450 shares of Common Stock as a result of
    the exercise of 11,562 employee options and 1,888 Zydeco Exploration
    Warrants (net of 573 Zydeco Exploration Warrants tendered as payment of
    the exercise price); (ii) granted options to purchase 272,000 shares of
    Common Stock pursuant to the 1996 Incentive Equity Plan, and (iii) the
    Company acquired all the outstanding stock of Wavefield Image, Inc., in
    exchange for 100,000 shares of Common Stock and an additional 150,000
    shares contingent upon the issuance of the U.S. patent in respect of the
    Wavefield Imaging Technology, which patent application has been allowed
    for patent issuance by the United States Patent and Trademark Office.

                                   DILUTION
   
  The net tangible book value of the Company as of March 31, 1997 was
$5,766,290 or $0.87 per share of Common Stock. Net tangible book value per
share of Common Stock represents the net tangible assets, less the total
liabilities, divided by the number of shares of Common Stock outstanding.
After giving effect to the sale by the Company of the 2,000,000 Shares offered
hereby at an assumed public offering price of $5.41 per share, and after
deducting underwriting discounts and commissions and estimated offering
expenses, the net tangible book value of the Company as of March 31, 1997
would have been $15,401,290 or $1.79 per share of Common Stock. This
represents an immediate increase in such net tangible book value of $0.92 per
share to existing stockholders and an immediate dilution of $3.62 per share to
new investors. The following table illustrates this per share dilution:

  The foregoing assumes no exercise of the Underwriters over-allotment option
or options, unit options and warrants after March 31, 1997. As of March 31,
1997, there were outstanding options, unit options or warrants to purchase an
aggregate of 5,627,822 shares of Common Stock, and the Company had also
reserved up to an additional 380,000 shares of Common Stock for issuance upon
the exercise of options which had not yet been granted under the Company's
1996 Incentive Equity Plan and 1996 Non-employee Director Stock Option Plan.
To the extent options, unit options or warrants are exercised, there will be
further dilution to new investors. See "Capitalization."

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
  The Company (formerly "TN Energy Services Acquisition Corp.") was
incorporated in June 1993. Other than raising capital and reviewing
acquisition candidates, the Company did not engage in any significant business
activities prior to December 1995. Zydeco Exploration, the Company's wholly
owned subsidiary, was incorporated as an independently owned corporation in
March 1994. Zydeco Exploration immediately commenced exploration activities in
the Louisiana Transition Zone. On December 20, 1995, the Company acquired all
the outstanding common stock and preferred stock of Zydeco Exploration
pursuant to a merger (the "Merger") and changed its name to Zydeco Energy,
Inc. For accounting purposes, the Merger has been treated as a
recapitalization of Zydeco Exploration with Zydeco Exploration as the acquiror
(a reverse acquisition). Accordingly, the historical financial statements
prior to December 20, 1995, are those of Zydeco Exploration. No pro forma
information giving earlier effect to the transaction has been presented since
the transaction was accounted for as a recapitalization.
   
  In May 1996, the Company entered into a license agreement with Dr. Norman
Neidell ("Neidell") for the use of the Wavefield Imaging Technology, the
benefits of which may substantially reduce the Company's total costs of
seismic data acquisition for certain surveys. On July 1, 1997, the Company
acquired Wavefield, the owner and licensor of the rights to the Wavefield
Imaging Technology. On July 3, 1997, the Company received notice that a patent
application in respect of the Wavefield Imaging Technology was allowed for
issuance by the United States Patent and Trademark Office. The Company expects
that the patent will be issued in a few months. See "Business and Properties--
Technology."     
 
  In February 1996, the Company obtained an exclusive seismic permit from the
State of Louisiana covering approximately 51,000 acres of state waters in
western Cameron Parish, Louisiana, which will expire on August 18, 1997. The
Company paid a fee of $783,754 for the permit. The Company may extend the
permit period to February 18, 1998 by payment of an additional fee of
$391,877. During such period the Company has the exclusive right to nominate
parcels of such area for competitive bidding for drilling rights. Under the
permit, the State of Louisiana is required to keep the information obtained
from the survey confidential for a period of ten years. See "Business and
Properties--West Cameron Seismic Project."
   
  In April 1996, the Company executed the Cheniere Exploration Agreement with
Cheniere, for the West Cameron Seismic Project, covering an area of land and
waters in western Cameron Parish, Louisiana, including the area covered by the
seismic permit described above. Cheniere holds an interest of 50% in the West
Cameron Seismic Project. In exchange for such interest, Cheniere has agreed to
fund the costs of seismic acquisition up to $13.5 million and 50% of such
costs in excess of $13.5 million. Such costs include the purchase of seismic
rights, the cost of lease options on the related onshore acreage of the West
Cameron Seismic Project, and data acquisition and processing of a 3D seismic
survey of the onshore and offshore areas. Cheniere may elect to discontinue
funding of the West Cameron Seismic Project at any time, in which case its
interest would be reduced pro rata in relation to total project costs. As of
July 1, 1997, Cheniere had made payments of $12.0 million against costs
incurred on the West Cameron Seismic Project of approximately $15.5 million.
See "Risk Factors--Need for Additional Financing."     
   
  In connection with the West Cameron Seismic Project, the Company began
onshore leasing and permitting in February 1996. Seismic data acquisition
commenced in August 1996 and was discontinued in early December due to weather
conditions and recommenced in April 1997. As of July 1, 1997, approximately
132,000 acres, out of a total of 146,000 acres to be surveyed, had been
surveyed and seismic data acquired.     
 
  The Company had originally negotiated a turnkey seismic services agreement
with a survey contractor, Grant Geophysical, Inc. ("Grant"), in an effort to
control some of the costs and risks associated with the West Cameron Seismic
Project survey. In December 1996, after Grant informed the Company it was
ceasing survey operations due to winter weather conditions, Grant filed for
protection and reorganization under Chapter 11 of
 
                                      19
<PAGE>
 
the U. S. Bankruptcy Code and is currently restructuring its operations. In
March 1997, the Company and Grant executed a new Master Geophysical Data
Acquisition Agreement (the "Grant Agreement"), providing for reimbursement of
Grant under a "cost plus" services arrangement, which could have the effect of
increasing seismic data acquisition costs. See "--Liquidity and Capital
Resources."
 
  The Company accounts for its oil and gas exploration and production
activities using the successful efforts method of accounting. Under this
method, acquisition costs for proved and unproved properties are capitalized
when incurred. Exploration costs, including geological and geophysical costs
and the costs of carrying and retaining unproved properties, are expensed.
Exploratory drilling costs are initially capitalized, but charged to expense
if and when the well is determined not to have found proved reserves. Costs of
productive wells, developmental dry holes, and productive leases are
capitalized and amortized on a property-by-property basis using the unit-of-
production method. The estimated costs of future plugging, abandonment,
restoration, and dismantlement are considered as a component of the
calculation of depreciation, depletion and amortization. Unproved properties
with significant acquisition costs are assessed periodically on a property-by-
property basis and any impairment in value is charged to expense.
 
RESULTS OF OPERATIONS
 
THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THREE MONTHS ENDED MARCH 31,
1996
 
  Oil and Gas Sales. Oil and gas sales increased by $122,459, or 49%, to
$373,994 for the quarter ended March 31, 1997 from $251,535 for the quarter
ended March 31, 1996. The increase was attributable to an increase in
production volumes of $67,482 and an increase in the average prices for oil
and natural gas of $54,977. The increased prices and volumes from oil and gas
in first quarter 1997, compared to the same quarter in 1996, demonstrate the
sensitivity of the Company's operations to price fluctuations and its current
dependence on a small number of producing wells. The following table sets
forth information concerning crude oil, and natural gas sales volumes, average
sales prices, and per barrel oil equivalent ("NBOE") operating costs
(excluding depreciation, depletion, and amortization hereinafter referred to
as "DD&A") for the Company's exploration and production activities for the
indicated periods:

  Operating Expenses. Exploration expenses increased $252,088, or 121%, to
$460,688 for the quarter ended March 31, 1997 from $208,600 for the quarter
ended March 31, 1996. The increase was primarily a result of increased
personnel associated with the Company's two exploration projects. Production
costs from the one working interest well decreased 13% to $5,690. DD&A expense
in the first quarter of 1997 increased $58,278, or 53%, to $168,643 from
$110,365 for the first quarter of 1996. The increase was principally a result
of additional depreciation and amortization on additions of computer equipment
and geophysical software.

  Other Income (Expense). Net other income decreased $21,280, or 29%, to
$51,531 for the three months ended March 31, 1997 compared to net other income
of $72,811, for the three months ended March 31, 1996, principally as a result
of decreased interest income due to the decrease in available cash.
 
  Net Loss. For the quarter ended March 31, 1997, operations resulted in a net
loss of $565,617 ($.09 per share) compared to a net loss of $388,566 ($.07 per
share) for the comparable period in 1996. The increase in net loss of
$177,051, or 46%, was due to increased revenue of $122,459, increased
operating expenses of $278,230, and a decrease in net other income of $21,280.
The $.02 increase in per share loss was also affected by the increased number
of shares of common stock outstanding in the first quarter of 1997,
principally due to the conversion of the preferred stock in July 1996.
 
YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995
 
  During 1996 and 1995, the Company's primary operations consisted of the
acquisition of federal and state oil and gas leases, the acquisition of 3D
seismic analysis hardware and software, the purchase of an interest in a gas
well which commenced production in January 1995, and the farmout of two leases
(one of which resulted in commercial production commencing in December 1995).
Exploration activities in 1995 also included a one-eighth participation in the
drilling of an exploratory well which resulted in a dry hole in March 1995.
Exploration activities in 1996 included a joint venture participation in the
drilling of one well that was abandoned in September 1996 without reaching the
well's primary objectives. The Company also initiated two seismic exploration
joint ventures, one in 1995 and one in 1996, with industry partners who are
required under the agreements to fund substantially all the Company's share of
the seismic project costs, up to certain limits. See "Note 2--Exploration
Agreements" in Notes to Consolidated Financial Statements.

(1) Excludes depreciation on seismic computer hardware and software of
    $488,521 and $278,297 for the years ended December 31, 1996 and 1995
    respectively.
 
  Oil and Gas Sales. Oil and gas sales increased by $1,252,992, or 740%, to
$1,422,227 for the year ended December 31, 1996 from $169,235 for the year
ended December 31, 1995. Of this increase, $856,961 was attributable to an
increase in production volumes and $396,031 was due to increases in the
average prices for oil and gas. Of the increase in oil and gas sales,
production from one well aggregated $1,007,613. This well commenced initial
production in December 1995 from a completion by Bois D'Arc Resources in which
 
                                      21
<PAGE>
 
the Company has an overriding royalty interest of 7.33% after payout (4.33%
before payout). Payout on this well occurred in June 1996. The Company's share
of production from this well was 229,501 mcf and 18,866 barrels of oil in
1996. The increased prices and volumes from oil and gas in 1996, compared to
1995, demonstrate the sensitivity of the Company's operations to price
fluctuations and its current dependence on a small number of producing wells.
   
  Operating Expenses. Exploration expenses increased $1,006,964, or 152%, to
$1,667,523 for the year ended December 31, 1996 from $660,559 for the year
ended December 31, 1995. The increase was primarily a result of one well
abandoned in September 1996 ($647,355) and increased exploration expense
($569,354) related to increased personnel associated with the Company's two
exploration projects. Production costs from the one working interest well
decreased 18% to $22,508. DD&A expense increased $238,478, or 61%, to $630,865
in 1996 from $392,387 in 1995. DD&A expense on oil and gas properties was
$142,344 in 1996 compared to $114,090 in 1995 and represented a significant
per equivalent barrel decrease as a result of increased reserves due to
revisions in engineering estimates (34,952 net equivalent barrels) principally
associated with the Bois D'Arc well. Depreciation and amortization expense of
equipment and software increased $210,224, or 76%, to $488,521 in 1996 from
$278,297 in 1995 principally as a result of additions aggregating $818,497 in
computer equipment and geophysical software. General and administrative
expense increased $800,343, or 175%, to $1,256,489 in 1996 from $456,146 in
1995 principally due to increases in personnel of $262,587 and estimated
additional costs of being a public company of approximately $172,549.     
 
  Other Income (Expense). Net other income increased $273,021 for the year
ended December 31, 1996 compared to a net expense of $23,814, for the year
ended December 31, 1995, principally as a result of increased interest income
due to the increase in available cash resulting from the Merger in December
1995.
 
  Net Loss. For the year ended December 31, 1996, operations resulted in a net
loss of $1,858,132 ($.30 per share) compared to a net loss of $1,173,646 ($.30
per share) for the year ended December 31, 1995. The increase in net loss of
$684,486 is comprised of increased revenue of $883,294, increased expenses of
$1,840,801, and increased other income of $273,021.
   
PERIOD FROM INCEPTION, MARCH 17, 1994, TO DECEMBER 31, 1995     
 
  From March 17, 1994, (the inception of Zydeco Exploration) through December
31, 1995, Zydeco Exploration's primary operations consisted of the acquisition
of federal and state oil and gas leases, the acquisition of 3D seismic
analysis hardware and software, the purchase of an interest in a gas well
which commenced production in early 1995, the farmout of two leases (one of
which resulted in commercial production in late 1995), and a one-eighth
participation in the drilling of an exploratory well, which resulted in a dry
hole. Due to its limited operations and because Zydeco Exploration had
completed only one full fiscal year, analysis of comparable interim periods is
not meaningful.
 
  Oil and Gas Sales. The Company had no revenue or oil and gas reserves during
1994. The Company's primary operations, prior to January 1, 1995, related to
(i) an initial capitalization, primarily through a private placement of
781,255 shares of convertible preferred stock at $3.20 per share which closed
on December 2, 1994; (ii) the acquisition of computer hardware equipment and
software; and (iii) the acquisition of certain oil and gas leases.
 
  Operating Costs and Expenses. Expenses incurred from inception through
December 31, 1994, consisted primarily of $72,981 of general and
administrative expenses and $71,268 of interest expense on advances to the
Company totaling approximately $1.3 million from related parties. These
advances were repaid with proceeds from the issuance of convertible preferred
stock. For the year ended December 31, 1995, the Company had revenues of
$586,752 consisting of seismic services revenue of $300,000, oil and gas
sales, primarily from one gas well which began production in January 1995 of
$169,235, and gains on sales of unproved leases of $117,517. Seismic services
revenue of $200,000 and the related cost of service were recognized under an
exchange agreement between the Company and a related party. Under this
agreement, the Company agreed to
 
                                      22
<PAGE>
 
provide 3D seismic analysis services in exchange for a license to use the
underlying seismic data owned by the related party. As this exchange agreement
represented an exchange of dissimilar goods, income and expense for 1995
reflects the gross value of seismic service revenues and related data costs
associated with this transaction. The remaining $100,000 of seismic services
revenue was realized in connection with performing certain seismic analysis
services under the Fortune Exploration Agreement. The Company had no revenues
for the comparable period from inception (March 17, 1994,) to December 31,
1994, since it had not yet commenced revenue producing activities following
organization.
   
  During the year ended December 31, 1995, the Company had exploration costs
of $261,956 primarily related to dry hole costs and related costs of plugging
and abandoning a well in which the Company participated in drilling in March
1995. Geological and geophysical expense of $398,603 was composed principally
of salaries and related personnel cost of $275,399 and geological and
geophysical software maintenance expense of $91,593. Production from the one
working interest well commenced in January 1995 and represented the increase
in production costs of $27,492 compared to 1994. The principal components of
the $456,146 of general and administrative expenses for 1995 included $294,527
of employee salaries and related costs, $41,225 of legal and accounting costs,
and $43,149 of office and facilities rent. DD&A expense totaling $392,387 for
1995 was comprised of DD&A of $114,090 on oil and gas properties and
depreciation of $278,297 primarily related to geophysical software (which is
depreciated over two years because of rapid changes in seismic-analysis
technology) and related equipment (which is depreciated over three to seven
years). General and administrative expenses for the comparable period from
inception (March 17, 1994) to December 31, 1994, were $72,981 consisting
primarily of legal and office expense related to initial office operations.
The Company paid no salaries in 1994. Increased revenues and expenses for the
year ended December 31, 1995, reflect increased operations resulting from
lease prospecting activities under the Fortune Exploration Agreement and
increased expense from the addition of employees.     
 
  Other Income (Expense). Net other expense increased $1,175, or 5%, to
$23,814 for the year ended December 31, 1995 compared to net other expense of
$22,639 for the period from inception (March 17, 1994) through December 31,
1994.
 
  Net Loss. For the year ended December 31, 1995, operations resulted in a net
loss of $1,173,646 ($.30 per share) compared to a net loss of $132,881 ($.03
per share) for the prior period. The increase in net loss of $1,040,765 was
due to increased revenue of $586,752, increased operating expenses of
$1,626,342 and increased net other expenses of $1,175.
 
LIQUIDITY AND CAPITAL RESOURCES
   
  The Company has generated funds from public and private equity offerings,
cash flow from the Company's operations, and cash payments made to it under
the Fortune Exploration Agreement and the Cheniere Exploration Agreement. The
Company may use its cash for any general corporate purposes except for the
funds advanced by Fortune and Cheniere, which are committed to the project
operations for which they were intended. Sources of funds include
approximately $10.1 million from the sale of securities in 1993, 1994 and
1995, advances in 1995 under the Fortune Exploration Agreement and $12.0
million, as of July 1, 1997, provided under the Cheniere Exploration
Agreement.     
   
  The Company expects that capital needs for 1997 will be satisfied through
cash on hand (including the proceeds from this Offering and internal cash
reserves) and cash available under the Cheniere Exploration Agreement.
Although Cheniere may elect to discontinue its funding of the remaining
payment of $1.5 million due on July 22, 1997, and thus substantially reduce
its interest in the West Cameron Seismic Project, Cheniere     
 
                                      23
<PAGE>
 
   
is responsible for funding 50% of the costs in excess of $13.5 million. The
Company believes that the Company has adequate existing cash to meet its
obligations incurred in connection with the West Cameron Seismic Project. The
Company has estimated approximately $13.2 million of costs in 1997 related to
the West Cameron Seismic Project, of which, Cheniere had advanced $6.7 million
as of July 1, 1997 and is expected to advance an additional $4.0 million. The
Company's share of 1997 costs budgeted for the West Cameron Seismic Project is
$2.5 million, which is included in its capital expenditure budget discussed
below. The Company's share of the budgeted costs could increase if Cheniere
elects to discontinue funding of the West Cameron Seismic Project. Such
additional costs and other capital needs may be funded from available cash of
the Company, the issuance of additional equity securities, including the
exercise of outstanding warrants and options of the Company, securing
additional project partners, or the sale of prospects, if any, identified by
the Company's projects. Depending upon the results of the West Cameron Seismic
Project, the Company may need additional funds in the future, principally in
order to undertake leasehold acquisitions, exploratory drilling or other
related costs. The Company does not maintain any credit facilities. The
Company may in the future explore the possibility of obtaining such a facility
in the event the Company increases oil and gas production through the
successful completion of oil and gas wells drilled by the Company. There can
be no assurance that the Company will be successful in securing additional
partners or additional project financing or credit financing. See "Risk
Factors--Need for Additional Financing."     
 
  The Company's current budget for its capital expenditures for 1997 is
approximately $3.0 million, including $2.5 million of West Cameron Seismic
Project costs (prior to any revisions for seismic acquisition costs) and
$393,000 related to the purchase of computer equipment and software. Other
significant additional capital expenditures may include the acquisition of
additional oil and gas leases, the drilling of prospects identified by the
Company, the acquisition of interests in producing wells, and other oil and
gas exploration and production related investment opportunities determined by
management and the Board of Directors to be in the interest of the Company.
The amount and timing of these expenditures will be dependent upon numerous
factors including the availability of capital to the Company, availability of
seismic data, the number and type of drilling prospects, if any, identified as
a result of the Company's 3D seismic analysis, the terms under which industry
partners may participate in the Company's prospects and the cost of drilling
and completing wells in the Louisiana Transition Zone and the Timbalier
Trench.
   
  Although the Company has incurred net losses since its inception in 1994,
cash flow from operating activities was $342,668 for the year ended December
31, 1996. The Company does not expect to generate operating cash flow or net
income in 1997. The Company expects to generate a net loss in 1997, including
its 50% share of geological and geophysical costs of approximately $2.5
million which it expects to incur on the West Cameron Seismic Project
primarily during the third quarter. The successful efforts method of
accounting generally requires that geological and geophysical expenses be
expensed when incurred.     
 
  The Company currently maintains a $300,000 bond required to hold its present
federal oil and gas leases. This bond is collateralized by a United States
Treasury Note. In the event the Company determines to act as operator on a
federal offshore lease or is otherwise required to increase its bonding by
federal or state authorities, such additional bonding may require significant
amounts of capital as collateral.

                            BUSINESS AND PROPERTIES
 
THE COMPANY
   
  Zydeco Energy, Inc. is an independent energy company engaged in the
exploration for oil and gas utilizing advanced 3D seismic and computer aided
exploration ("CAEX") techniques. The Company believes it is one of the few
independent exploration companies with comprehensive in-house technology and
expertise enabling it to use the most recent advances in such 3D seismic and
CAEX technology. Such technology includes the Wavefield Imaging Technology, a
data processing technique designed to substantially reduce the cost of 3D
seismic data acquisition for certain surveys while improving the resolution of
the subsurface image. Zydeco's geophysicists design the seismic data
acquisition survey, manage the acquisition of seismic data and process and
interpret the resulting data. The Company believes that its technology and
expertise enable it to acquire and analyze seismic data efficiently over large
geographical areas. The Company attempts to concentrate its efforts in areas
previously unexplored with advanced 3D seismic applications. Based upon
analysis of processed data, Zydeco personnel identify and rank potential oil
and gas drilling prospects for leasehold acquisition. The Company intends to
enter into agreements with experienced industry partners for the development
of its prospects and retain significant non-operating production interests in
those prospects. Zydeco's current exploration efforts are focused on the
Louisiana Transition Zone.     
 
STRATEGY
 
  The Company's primary objective is to discover and develop oil and gas
reserves and increase cash flow through exploration, prospect identification
and participation in projects to develop such prospects. In pursuing this
strategy the Company intends to:
   
  Continue Focused Exploration Activities. The Company focuses its efforts in
geologic areas worldwide that it believes are underexplored with 3D seismic
techniques and have the potential for substantial oil and gas reserves. Such
areas include geologically complex trends with characteristics that have
discouraged exploration in the past due to difficult seismic data acquisition
and analysis using conventional methods. The Company believes that use of its
Wavefield Imaging Technology and the most advanced available 3D seismic
processing techniques provides it with the capability to economically collect
and evaluate seismic data for such areas.     
   
  Continue Development of Industry Leading Seismic Technology and Expertise.
The Company believes the seismic data collection, processing and analysis
techniques it employs are significantly more advanced than those commonly used
in the industry. The Company intends to continue to expand its exploration
expertise through acquisition of high speed computers and parallel processing
software as they become available, integration of in-house capabilities and,
when appropriate, collaboration with individuals and other companies in the
development of new seismic technologies. The Company believes its Wavefield
Imaging Technology gives it a current advantage over exploration companies
that do not have access to it by substantially reducing the costs of seismic
data acquisition for certain surveys and improving spacial resolution in the
seismic imaging process. The Company may exploit its Wavefield Imaging
Technology by application to both its own seismic surveys and, through joint
ventures or similar arrangements, to seismic surveys by other companies.     
 
  Pursue Joint Ventures. The Company intends to pursue exploration and
development joint ventures with strategic industry partners in order to (i)
obtain funds necessary to explore for and identify potential prospects; (ii)
control and reduce the Company's exposure to the risks related to the
drilling, completion, production operation, and abandonment of properties;
and, where applicable, (iii) utilize the bonding and insurance capabilities of
experienced operating partners in order to be able to purchase leases and
drill wells in the offshore federal domain without having to collateralize
these activities with the substantial bonding and insurance amounts required
pursuant to governmental legislation.
 
IMPLEMENTATION
 
  Identify Areas Believed to Have Underexplored Potential. The Company intends
to continue to identify areas that it believes have underexplored potential
for substantial oil and gas reserves. Such areas include coastal transition
zones and similar areas that have characteristics that make seismic data
acquisition and analysis
 
                                      25
<PAGE>
 
difficult and expensive using conventional methods. For example, seismic data
in the coastal transition zones is difficult and expensive to acquire due to
the combinations of land and marine recordings that must be obtained across
the marshlands, bays, highland, and open water areas. Different types of
sources and receivers may be required for a true transition survey over a
beach area which complicates the processing and quality control of a seismic
survey. Surf related noise creates additional complications for a coastal
transition zone seismic survey. The Company's West Cameron Seismic Project in
the Louisiana Transition Zone is an example of such a survey.
   
  Acquire Seismic Rights or Proprietary Data. Once the Company has identified
an area of interest, it then seeks to obtain the rights to acquire seismic
data and engages a contractor to shoot 3D seismic data in a survey designed by
the Company for processing with the Wavefield Imaging Technology. The Company
may also purchase existing seismic data if it is available and can be usefully
processed with the Company's technical resources. The ability to assemble the
rights to shoot seismic data over large areas may be important to the success
of a 3D survey. A seismic survey for 3D analysis must gather data over an area
broader than the subsurface area intended for analysis, especially for deeper
objectives. Data from a broader area is necessary because the data from the
edges of a seismic survey cannot produce 3D imaging of the immediate
subsurface. To effect a proper 3D image requires a significant distance
between the sources and receivers which is not available at the edges of the
survey. In its West Cameron Seismic Project, the Company has assembled survey
rights over approximately 151,000 acres from highly fragmented ownership.     
 
  Identify Prospects. The seismic data is then processed or reprocessed and
then interpreted to identify potential prospects. Such processing includes
correlating the seismic data with subsurface well control and historical
production data from similar properties, and integrating all such available
data with enhanced 3D structural and stratigraphic imaging and attribute
analysis techniques by the Company's expert geophysicists and geologists. The
decision to drill any exploratory prospect is based on an analysis of the
economic risk associated with the potential return. Such analysis involves a
number of factors, including: (i) the availability of leases on reasonable
terms and permits for the prospect; (ii) the results of the review and
analysis of the seismic data, including the results of 3D seismic surveys;
(iii) the availability of sufficient capital resources to the Company and the
other participants for the drilling of the prospect; (iv) the approval of
other participants in the drilling of the prospect after additional data has
been compiled; (v) rig availability; and (vi) economic conditions at the time
of drilling, including prevailing and anticipated prices for crude oil and
natural gas.
 
  Acquire Leases and Drilling Rights. The Company acquires leases and
concessions for the potential prospects it identifies. Depending on whether
governmental or private individuals own the property in the area of interest
to the Company, the Company may be able, or required, to acquire such rights
prior to acquisition of the seismic data or it may wait until after
identifying potential prospects before acquiring any leases or drilling
rights. In the case of state properties, an interested party must nominate a
property for bid. The right to survey and/or lease the property is then
publicly auctioned by the state government. Leases for federal properties
available for drilling are publicly auctioned at least once each year. In the
case of privately held land or foreign concessions the right to explore the
property is normally privately negotiated.
 
  Establish Exploration Joint Ventures and Partnerships. Once the Company has
identified potential prospects and obtained leases and drilling rights for the
potential prospects, the Company may enter into agreements with experienced
industry partners for drilling and development. The Company may enter into a
joint venture for the drilling and development of the prospect or it may
farmout or sell the prospect for a combination of cash and/or a retained
interest. The Company will seek partners with proven records at managing
drilling and production activities in the area of the prospect. Generally, the
Company intends to retain only a nonoperating production interest with respect
to its prospects.
 
TECHNOLOGY
 
  Traditionally, seismic analysis involved the acquisition, processing and
interpretation of seismic data collected along a single line of seismic
detectors and sources. Processing of the resulting data created a two
dimensional cross section of the earth's subsurface beneath this line. This
technique constitutes 2D seismic
 
                                      26
<PAGE>
 
surveying ("2D seismic"). The advent of high speed, large storage capacity
computers and advanced geophysical software development has permitted the
acquisition, processing and interpretation of seismic data collected in an
areal array, usually from multiple relatively closely spaced lines of seismic
detectors and sources. Processing of the resulting data creates a three
dimensional image of the earth's subsurface. This technique constitutes 3D
seismic surveying ("3D seismic"). 3D seismic provides a substantially improved
image for interpretation and analysis than the cross section created by 2D
seismic. As a result, the industry's success rate with respect to the drilling
of prospects has risen with the adoption of 3D seismic technology.
 
  Basic 3D seismic imaging and analysis are now routinely used in oil and gas
exploration. The goal of 3D seismic processing is to image the subsurface for
detailed structural and stratigraphic interpretation. When sound waves from
seismic sources move through various strata of rock, the speed and the angle
of transmission of these waves change from one strata to another. If the
strata is tilting or "dipping", the path of the sound waves is further
complicated. These factors will cause the seismic events indicating structural
changes to be misplaced from their true locations unless the data is corrected
by processing. The basic processes used in 3D seismic processing are Dip-
Moveout ("DMO"), Common Depth Point stacking ("CDP") and poststack migration.
Each of these processes is intended to adjust the collected seismic data to
more accurately image the subsurface.
 
  Migration is an imaging process that "relocates" seismic events to account
for changes in the dip of the underlying strata and moves those events into
their proper location. This process requires knowledge of the velocity of the
sound waves as they are transmitted and reflected through the strata.
 
  For approximately the past thirty-five years, the most commonly used
technique to improve the signal quality of seismic data has been CDP stacking.
This technique simply adds or "stacks" the seismic traces which have a common
mid-point between each source and receiver after time correcting the data for
the offset or distance between the sources and the receivers.
 
  Dip-Moveout (DMO) is a more recently developed process to correct the CDP
data so that dipping events will stack or focus better using a common
velocity. This technique is sometimes referred to as a partial migration.
Nevertheless, migration is a necessary process applied poststack, i.e. after
summation of the common midpoint traces.
 
  Continuing improvements in computing speed and capacity resulted in the
development of more advanced 3D processing techniques. These advanced 3D
processing techniques include prestack migration which migrates the individual
data traces prior to any summation of the data with respect to either time or
depth. Prestack migration requires a more accurate analysis of sound velocity
through the various subsurface strata present in the area surveyed than the
more commonly used sequence of CDP and poststack migration. Determining an
accurate velocity model is an iterative process requiring close coordination
between the processing and interpretation experts. Not all oil and gas
exploration companies are capable of performing prestack migration processing.
   
  Most recently, the Wavefield Imaging Technology, developed by Dr. Norman S.
Neidell, an independent researcher, represents a further advancement of 3D
seismic processing and analysis. Wavefield Imaging is a method of producing a
more finely resolved image of the subsurface than is possible with previously
existing 3D processing techniques. Consequently, Wavefield Imaging Technology
permits the Company to use more broadly spaced seismic receivers in its
surveys thereby reducing the cost of data acquisition for certain surveys and
improving the resolution of the subsurface image. Under the present survey
configuration used by the Company in its West Cameron Seismic Survey, the
Wavefield Imaging Technology is limited to analysis of seismic objectives
below 8,000 feet. The Company believes the technology may also be applied in
the analysis of shallower objectives by increasing receiver and sound source
densities, although with diminishing cost advantages. In May 1996, the Company
entered into a license with Dr. Neidell for the Wavefield Imaging Technology.
       
  On July 1, 1997, the Company acquired all of the outstanding capital stock
of Wavefield, the owner of the Wavefield Imaging Technology. Pursuant to the
acquisition, the Company issued 100,000 shares of Common Stock to shareholders
of Wavefield Image, Inc., including its principal shareholder, Dr. Norman S.
    
                                      27
<PAGE>
 
   
Neidell, inventor of the Wavefield Imaging Technology. In addition, the
Company expects to issue an additional 150,000 shares of Common Stock to the
shareholders of Wavefield for a patent of the Wavefield Imaging Technology
which the Company received notice that the patent application has been allowed
for issuance by the United States Patent and Trademark Office. The Company
also entered into a four year agreement with Dr. Neidell regarding his
employment with the Company. In addition, the Company granted Dr. Neidell
options, vesting over four years, to purchase 150,000 shares of the Company's
Common Stock. As a result of the acquisition, the Company owns the Wavefield
Imaging Technology subject to licenses granted previously by Wavefield. Prior
to the acquisition, Wavefield granted licenses for the Wavefield Imaging
Technology to one major oil company and one foreign company and offered a
license to another foreign company. In addition, Dr. Neidell's employment
agreement with the Company grants Dr. Neidell an option to obtain a limited,
nontransferable license to the Wavefield Imaging Technology under certain
conditions. Currently, the Company is not aware of any company, including the
licensees, employing Wavefield Imaging Technology in the design of its seismic
surveys and processing of its seismic data. The Company and Dr. Neidell have
also agreed to negotiate in good faith to form a joint venture between them to
own and exploit any non-seismic applications of the Wavefield Imaging
Technology.     
 
  The Company believes it is one of the few independent exploration companies
to perform both 3D seismic data processing and seismic interpretation in-
house. As described above, prestack migration involves an iterative process.
Most independent exploration companies use outside contractors to process
their 3D data in this iterative process. However, this iterative process
requires continual free exchange of information between the data processing
experts and the interpretation experts. Use of outside contractors can result
in slower turn-around time for processing. In addition, exploration companies
are often reluctant, for confidentiality reasons, to disclose more than the
necessary data to the outside processing experts and this may further limit
the effectiveness of the process. Finally, outside processing contractors
generally do not specialize in processing data from any particular area. The
Company believes processes such as prestack migration analysis can be most
effectively and efficiently accomplished by performing seismic survey design,
data processing and interpretation in-house. The Company believes performance
of such work in-house allows the Company to integrate all of those processes
and thereby produce a more accurate image of the subsurface to identify
prospects for leasing and drilling.
 
  The Company has selected and assembled the computers and software necessary
to perform this advanced 3D seismic imaging and analysis. This equipment is
specifically designed to handle the scale and complexity of large scale
seismic projects such as the Company's West Cameron Seismic Project. The
Company has also assembled a team of geophysicists and geologists with
expertise in these advanced 3D processes. The Company believes its personnel,
software and Wavefield Imaging Technology combined with its hardware
processing capacity represents unique in-house capabilities with respect to
advanced 3D seismic analysis leading to more accurate 3D images at a reduced
cost. See "Risk Factors--Technology."
 
GEOLOGIC AND GEOPHYSICAL EXPERTISE
   
  The Company has employed a group of talented and experienced geologists and
geophysicists. The Company currently employs three geologists and eight
geophysicists. These experts have an average of 20 years of experience in
seismic imaging and analysis. As discussed above, the Company believes this
in-house expertise is a critical factor in enabling the Company to effectively
and efficiently use the most recent developments in 3D seismic imaging.     
 
LOUISIANA TRANSITION ZONE AND OTHER AREAS OF INTEREST
 
  The Company has identified and is evaluating numerous potential prospects
offshore in the Louisiana Transition Zone and the Timbalier Trench, the
Company's current principal areas of concentration.
 
  Louisiana Transition Zone. The Louisiana Transition Zone is a narrow trend
paralleling the coastline of Louisiana. It is approximately six miles wide
(three miles on either side of the beach) and extends approximately 300 miles
from the Sabine River eastward to the Mississippi River. Water depths in the
Louisiana Transition Zone range up to approximately 40 feet. The Louisiana
Transition Zone contains the Miocene Trend which has produced many of the
largest oil and gas fields developed in the continental United States and its
territorial waters. Productive zones within the Miocene Trend have excellent
reservoir characteristics and have historically exhibited multiple pay zones,
which allow a single strategically placed well bore to drain multiple
reservoirs. The western portion of the Louisiana Transition Zone contains the
gas prolific Planulina sands.
 
                                      28
<PAGE>
 
  The Louisiana Transition Zone is populated with salt domes with numerous
radial and tangential faults surrounding the salt domes. The use of advanced 3D
seismic technology is essential to the exploration of such salt features and
fault blocks. Historically, there have been relatively few 3D surveys conducted
in the Louisiana Transition Zone because of the relatively high cost of such
surveys compared to land or deepwater surveys. The high cost is a result of the
problems associated with seismic surveys in coastal transition zones discussed
in "Implementation" above. Seismic activity has also been limited due to
wildlife sanctuaries. Leases in this area are controlled by sophisticated land
owners onshore and the State of Louisiana within three miles of the beach
offshore. Permits for 3D acquisition require the consent of all landholders and
all leaseholders. Such consents are not required in Federal waters. Thus,
seismic contractors have been reluctant to conduct speculative 3D surveys due
to the difficulty of permitting acreage in the Louisiana Transition Zone. Due
to these limitations, this zone is considered a "seismically blind" area and is
thus reflected on virtually every onshore and offshore 2D seismic coverage map
for the State of Louisiana as an area of "no seismic coverage." Given this low
level of historical exploration and the high recovery factors characterizing
the Louisiana Transition Zone, the Company believes that this zone has the
potential for containing substantial undeveloped oil and gas reserves. Many of
these prospective areas in the Louisiana Transition Zone are located in shallow
waters near existing pipeline infrastructure. As a result, reserves underlying
these areas are generally less costly to develop and connect to pipeline
infrastructure than reserves in deeper water areas.
   
  Timbalier Trench. The Timbalier Trench is a narrow, circuitous channel
approximately seven miles wide and situated 600 feet beneath the floor of the
Gulf of Mexico. This trench is an ancestral channel of the Mississippi River.
Water depths range from 40 to 130 feet in the Company's prospect areas. The
Timbalier Trench contains an irregular shale section deposited over a normal
sedimentary section. The differences in the reflective qualities of these
sections cause a distortion in the penetration and recording of energy from a
seismic source which results in a lack of data continuity and resolution. This
lack of continuity and resolution with respect to seismic shot in the Timbalier
Trench has historically been considered a "poor quality data" area because
abnormally low seismic velocities in the shale "Trench" create data processing
problems.     
 
WEST CAMERON SEISMIC PROJECT
   
  In August 1996, the Company commenced the West Cameron Seismic Project, an
extensive 3D seismic exploration program in a part of the Louisiana Transition
Zone in western Cameron Parish, Louisiana. The Company anticipates the West
Cameron Seismic Project will encompass approximately 146,000 gross acres. At
the core of the West Cameron Seismic Project is a 51,000 acre exclusive seismic
permit on state waters obtained by the Company from the State of Louisiana.
    
  Options and Permits. In connection with the West Cameron Seismic Project, the
Company has negotiated seismic options covering approximately 35,775 gross
acres (32,398 net acres) and has secured seismic permits covering approximately
98,454 gross acres (97,762 net acres). Options and permits aggregating 57,913
gross acres (54,325 net acres) are located onshore in Cameron Parish,
Louisiana, including the exclusive seismic permit with the State of Louisiana.
In connection with the exclusive seismic permit, for eighteen months,
commencing February 1996, the Company has the exclusive right to acquire
seismic data on the State's acreage and nominate any of the acreage for
competitive lease bids. In Louisiana, a public auction of leases is held
approximately 90 days after the property is nominated for bid and the auction
is generally announced only 30 days prior to the auction date. A bidder at the
auction may bid on all or only a portion of the property nominated for bid. The
Company is obligated to deliver to the State of Louisiana a copy of a 3D
seismic survey over the state acreage included in the permit or pay a
substantial penalty. Under the Company's seismic permit, the State of Louisiana
is required to keep the information obtained from the survey confidential for a
period of ten years. The Company can, and currently intends to, extend the time
period for delivery of the survey for a six month period ending February 14,
1998 for an additional payment of $391,877.
 
  Exploration Agreement. In April, 1996, the Company executed the Cheniere
Exploration Agreement covering the West Cameron Seismic Project. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--General". The Cheniere Exploration Agreement provides for aggregate
payments to Zydeco of at least $13.5 million to fund the costs of seismic
acquisition, including the purchase of
 
                                       29
<PAGE>
 
   
seismic rights or lease options on the related onshore acreage of the West
Cameron Seismic Project, and to complete data acquisition and processing of a
3D seismic survey of the onshore and offshore areas. The Cheniere Exploration
Agreement, as amended, provides that Cheniere may receive a 50% interest in
the West Cameron Seismic Project and any leases acquired as a result thereof
through May 2001, based on Cheniere completing its funding of the initial
$13.5 million and 50% of any costs incurred thereafter. As of July 1, 1997,
Cheniere had funded a total of $12.0 million pursuant to the Cheniere
Exploration Agreement. The Cheniere Exploration Agreement provides that
Cheniere may discontinue funding at any time and its interest would then be
reduced pro rata based on the West Cameron Seismic Project's total cost.     
 
  Cheniere has the right to farm out a portion or all of its interest in each
prospect identified in the project to Zydeco under a put arrangement in the
Cheniere Exploration Agreement. In the event of such a farmout, Cheniere would
retain a 1% overriding royalty interest, as to its interest in the project,
convertible into a 10% working interest as to its interest in the project,
after Zydeco, or its partners, has recouped the cost of drilling, completion,
and hook-up of completed wells. Should Cheniere farm out a smaller working
interest to Zydeco, the overriding royalty and after-payout working interests
would be proportionately reduced. Zydeco has similar farmout rights under the
Cheniere Exploration Agreement.
 
  Seismic Data Acquisition. In September 1996, seismic data acquisition
commenced under a turnkey seismic contract with Grant. Data acquisition
operations were suspended for the winter in December 1996. In December 1996,
Grant filed for protection under Chapter 11 of the U. S. Bankruptcy statutes.
The Company executed a new contract with Grant in March 1997, and seismic data
acquisition operations recommenced in April 1997. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations--Liquidity and
Capital Resources."
   
  Data Analysis. In January 1997, the Company completed the assembly of an
exploration team of geophysicists, geologists, and seismic analysts and the
integration of its 3D seismic interpretive hardware and software. As of July
1, 1997, the Company had collected seismic data for analysis and
interpretation on approximately 90% of the original West Cameron contract
acreage. The Company is presently analyzing such data and applying various
advanced 3D seismic processing techniques to improve data resolution and to
develop routines for more complicated processes, including pre-stack migration
and velocity analyses. These techniques will also be used in analyzing future
data obtained for the West Cameron Seismic Project. While the Company believes
the preliminary data results are promising, the exploration potential of the
data is still not known and identification of prospects would be premature.
The analysis of the exploration potential of the data will be dependent on
further seismic processing and analysis and the availability of additional
data covering the West Cameron Seismic Project area.     
 
FORTUNE PROJECT
   
  In February 1995, Zydeco Exploration entered into the Fortune Exploration
Agreement with a predecessor of Fortune. Pursuant to the Fortune Exploration
Agreement Fortune advanced to Zydeco $4.8 million and agreed to advance 50% of
any additional funds necessary for the acquisition and processing of seismic
data and acquiring leases on certain of the potential prospects described in
"Potential Prospects and Leases" below in exchange for Fortune's right to
maintain up to a 50% interest in such prospects. Fortune's interest in such
potential prospects may drop below 50% if it elects not to contribute to
development costs for such potential prospects. Since the inception of the
Fortune Exploration Agreement, Zydeco has spent approximately $2.6 million to
acquire and maintain leases and to purchase and process seismic data. In June
1997, Fortune exercised its right under the Fortune Exploration Agreement to
have returned to it $2.2 million in unexpended funds which it had previously
advanced to the Company to cover anticipated lease acquisition and exploration
expenses relating to the co-owned prospects. In addition to the initial
potential prospects, Zydeco and Fortune have established areas of mutual
interest ("AMIs") adjoining each potential prospect. No assurance can be given
that any new projects within the AMIs will be identified.     
 
  Fortune has the right to farm out a portion or all of its interest in each
prospect to Zydeco under a put arrangement in the Fortune Exploration
Agreement. In the event of such a farmout, Fortune would retain a 1%
overriding royalty interest, as to its interest in the prospect, convertible
into a 10% working interest in its interest in the prospect after Zydeco or
its partners, have recouped the cost of drilling, completion, and hook-up
 
                                      30

of the well. Should Fortune farm out a smaller working interest to Zydeco, the
overriding royalty and after-payout working interests would be proportionately
reduced. Zydeco has similar farmout rights under the Fortune Exploration
Agreement.
 
POTENTIAL PROSPECTS AND LEASES
   
  Undeveloped Properties. The Company has identified and is evaluating a
number of potential prospects outside of the West Cameron Seismic Project
under oil and gas leases in which the Company has an interest. These leases
are located primarily in the Miocene Trend of southern Louisiana. The
potential prospects have generally been identified by shooting or purchasing
certain 2D and 3D seismic data; processing or reprocessing thereof, and
correlating the seismic data with subsurface well control and historical
production data from similar properties. As of July 1, 1997, the Company held
oil and gas leases covering approximately 21,480 gross acres (11,326 net
acres) in the Louisiana Transition Zone and the Timbalier Trench. The Company
owns 100% of the interest in five of the potential prospects in the Bay
Marchand and Timbalier Bay areas. The Company owns a 50% interest in 17 of the
potential prospects in which Fortune owns the remaining 50% interest, and the
Company owns limited interests in the four other potential prospects which are
all located in the Louisiana Transition Zone. The Company is currently
offering to sell interests or farmout five of the potential prospects in which
it has an interest in the Bay Marchand area. The Company is currently in the
process of acquiring 3D seismic data and analyzing such data for certain of
the other potential prospects. As of December 31, 1996, the Company had
licensed 3D seismic data covering approximately 88,320 acres offshore
Louisiana encompassing approximately 10,366 gross acres in which the Company
has leases covering all or portions of the potential prospects. In addition,
during 1997, the Company licensed 3D seismic data covering approximately
55,000 acres over federal and state waters adjacent to the Company's West
Cameron Seismic Project. The Company does not have any leases in the area
covered by the recently acquired data.     
 
  The Company is in the process of collecting and analyzing the seismic data
for the West Cameron Seismic Project. As a result, the Company has not
commenced any lease acquisitions in that area. The Company acquired Fortune's
interest in a 116 acre potential prospect in the area of the West Cameron
Seismic Project to eliminate any conflict between the AMIs for the West
Cameron Seismic Project and the Fortune project.
 
  Lease Terms. All the leases currently held by the Company are Federal or
State of Louisiana offshore leases. The Company's leases have expiration dates
ranging from 1997 to 2001. Federal offshore leases generally provide for a
minimum royalty of 16.67%, have a primary lease term of five years, comprise
an approximately 5,000 acre lease block, and are administered by the U.S.
Department of Interior Minerals Management Service (the "MMS"). Annual rentals
on Federal leases are $5.00 per acre. In general, the Company's federal leases
consist of portions of 5,000 acre lease blocks. If production is not
established or an extension is not obtained during the primary term, the lease
terminates. Louisiana state leases are administered by the State Mineral Board
of the State of Louisiana and generally provide for: (i) a minimum royalty of
20%; (ii) a five year primary term; and (iii) annual rentals in an amount
equal to 50% of the original lease acquisition cost. Generally, title to state
and federal leases is merchantable in all respects and operations thereon are
not normally subject to litigation resulting from the legal doctrine of
adverse possession or any other similar challenge to title.
 
DRILLING ACTIVITIES
 
  In May 1994, Zydeco purchased a 10% working interest in a tested but
unproven well in the Falcon Prospect. In January 1995, the well began
production of natural gas. In April 1995, Bois D'Arc Exploration successfully
tested a well in the Thunder West prospect as a farmout from Zydeco. Zydeco
has a 7.33% overriding royalty interest in the well. In October 1994, Zydeco
purchased a one-eighth working interest and participated in an exploratory
well in the Bon Ton Prospect. In March 1995, the well was determined to be a
dry hole and was plugged and abandoned. Subsequently in August 1995, the
Company acquired a 50% interest in an adjacent state lease in the Bon Ton
Prospect. In March 1996, Zydeco and Fortune farmed out the Polaris Prospect to
FW Oil Interests, Inc. ("FW"). FW commenced drilling a well in July 1996,
which was unsuccessful and abandoned in October 1996.
 
  In August 1996, the Company purchased certain non-producing leasehold
interests from Neomar Resources, Inc., an affiliate of Mr. Sam B. Myers, Jr.,
Chief Executive Officer of the Company, and participated in the
 
                                      31
<PAGE>
 
drilling of an exploratory well located in Timbalier Bay in state waters
offshore Louisiana. See "Management--Certain Relationships and Related
Transactions." The Company paid $187,500 for a 37.5% working interest in the
prospect leases, subject to a 25% back-in interest by Neomar after payout.
Drilling of the exploratory well commenced in August 1996 and was abandoned in
September 1996 for mechanical reasons without testing the well's primary
objectives. Neomar Resources, Inc. participated for a 41.2% working interest
in the well. The Company incurred $647,355 in exploration expense in 1996 in
connection with the drilling and abandonment of the well. At December 31,
1996, the Company had undertaken to sell or farm out all or a portion of its
interest in this prospect.
 
OIL AND GAS RESERVES
 
  The Company engaged Ryder Scott Company, Petroleum Engineers ("Ryder Scott")
to estimate the proved oil and gas reserves of the Company as of December 31,
1996, for all of the Company's proved properties. Ryder Scott is an
independent oil and gas reserve engineering firm. Prior to 1995, the Company
had no proved oil and gas reserves. Ryder Scott was also engaged to estimate
the future net revenues to be derived from such properties. In preparing their
report, Ryder Scott reviewed and examined such geological, economic,
engineering, and other data provided by the Company as considered necessary
under the circumstances, and examined the reasonableness of certain economic
assumptions regarding estimated operating and development costs and recovery
rates in light of economic circumstances as of December 31, 1996. As of
December 31, 1996, the proved oil reserves were estimated to be 10,052 Bbls.
and the proved natural gas reserves were estimated to be 243,000 Mcf.
 
  There are numerous uncertainties inherent in estimating quantities of
reserves and in projecting future rates of production and timing of
development expenditures, including many factors beyond the control of the
producer. The reserve data set forth in this Prospectus represent only
estimates. Reserve engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
way, and the accuracy of any reserve estimate is a function of the quality and
quantity of available data and of engineering and geological interpretation
and judgment. As a result, estimates of different engineers often vary. In
addition, results of drilling, testing, and production subsequent to the date
of an estimate may justify revision of such estimate. Accordingly, reserve
estimates at a specific point in time are often different from the quantities
of oil and gas that are ultimately recovered, which differences may be
significant. Additionally, the estimates of future net revenues from proved
reserves of the Company and the present value of future net revenues are based
upon certain assumptions about future production levels, prices, and costs
that may not prove correct over time. The meaningfulness of such estimates is
highly dependent upon the accuracy of the assumptions upon which they were
based.
 
INFORMATION RELATING TO OIL AND GAS PROPERTIES
 
  Production. The Company had no oil and gas reserves or production prior to
1995. The following table summarizes the sales volumes of the Company's net

(1) "Productive Wells" are producing wells and wells capable of production,
    and include gas wells awaiting pipeline connections or necessary
    governmental certifications to commence deliveries and oil wells to be
    connected to production facilities.
(2) "Developed Acres" include all acreage (on a leasehold basis in the United
    States) as to which proved reserves are attributed, whether or not
    currently producing, but exclude all producing acreage as to which the
    Company's interest is limited to royalty, overriding royalty, and other
    similar interests.
(3) "Undeveloped Acres" are considered to be those lease acres on which wells
    have not been drilled or completed to a point that would permit the
    production of commercial quantities of oil or gas regardless of whether
    such acreage contains proved reserves.

</TABLE>
--------
(1) "Wells Drilled" refers to the number of wells completed at any time during
    the fiscal year, regardless of when drilling was initiated. The term
    "completed" refers to the installation of permanent equipment for the
    production of oil or gas, or, in the case of a dry hole, to the reporting
    of abandonment to the appropriate agency.
(2) A dry well is an exploratory or a development well found to be incapable
    of producing either oil or gas in sufficient quantities to justify
    completion as an oil or gas well. A productive well is an exploratory or a
    development well that is not a dry well.
 
  At December 31, 1996, the Company was not participating in any drilling
wells.
 
PROPRIETARY RIGHTS AND LICENSES
   
  The Company believes that its success depends primarily on the innovative
skills, technical competence, and sales and marketing abilities of its
personnel rather than upon the ownership of patents or other intellectual
property. The Company has obtained licenses to use all software necessary to
its business. On July 3, 1997, the Company received notice that an application
in respect of the Wavefield Imaging Technology has been allowed for issuance
of a patent by the United States Patent and Trademark Office. The Company
expects that the patent will be issued in a few months. As discussed above,
the Company has acquired a non-exclusive license to use the Wavefield Imaging
Technology throughout the world and an exclusive license to use it in the
Louisiana Transition Zone. See "--Strategy" and "--Technology."     
 
COMPETITION AND MARKETS
 
  Competition in the Louisiana Transition Zone and the Timbalier Trench is
intense, particularly with respect to the acquisition of producing properties
and proved undeveloped acreage. The Company competes with the major oil
companies and other independent producers of varying sizes, all of which are
engaged in the exploration, development, and acquisition of leases and
producing properties. Many of the Company's competitors have financial
resources and exploration and development budgets that are substantially
greater than those of the Company, which may adversely affect the Company's
ability to compete, particularly in regions other than the Gulf Coast.
 
  The availability of a ready market for and the price of any hydrocarbons
produced will depend on many factors beyond the control of the Company,
including the extent of domestic production and imports of foreign oil, the
marketing of competitive fuels, the proximity and capacity of natural gas
pipelines, the availability of transportation and other market facilities, the
demand for hydrocarbons, the political conditions in the Middle East, the
effect of federal and state regulation of allowable rates of production,
taxation and the conduct of drilling operations, and federal regulation of
natural gas. In the past, as a result of excess deliverability of natural gas,
many pipeline companies have curtailed the amount of natural gas taken from
producing wells, shut-in some producing wells, significantly reduced gas taken
under existing contracts, refused to make payments under applicable "take-or-
pay" provisions, and have not contracted for gas available from some newly
completed
 
                                      34
<PAGE>
 
wells. The Company can give no assurance that such problems will not arise
again. In addition, the ongoing restructuring of the natural gas pipeline
industry will eliminate the gas purchasing activity of traditional interstate
gas transmission pipeline buyers. See "--Governmental Regulation" and "Risk
Factors--Competition."
 
  Producers of natural gas, therefore, will be required to develop new markets
among gas marketing companies, end users of natural gas, and local
distribution companies. All of these factors, together with economic factors
in the marketing area, generally may affect the supply and/or demand for oil
and gas and thus the prices available for sales of oil and gas.
 
GOVERNMENTAL REGULATION
 
  The Company's oil and gas exploration, development, production, and related
operations are subject to extensive rules and regulations promulgated by
Federal and state agencies. Failure to comply with such rules and regulations
can result in substantial penalties. The regulatory burden on the oil and gas
industry increases the Company's cost of doing business and affects its
profitability. Because such rules and regulations are frequently amended or
reinterpreted, the Company is unable to predict the future cost or impact of
complying with such rules and regulations.
 
  Production. In most, if not all, areas where the Company may conduct
activities, there may be statutory provisions regulating the production of oil
and natural gas under which administrative agencies may promulgate rules in
connection with the operation and production of both oil and gas wells,
determine the reasonable market demand for oil and gas, and establish
allowable rates of production. Such regulations may restrict the rate at which
the Company's wells produce oil or gas below the rate at which such wells
would be produced in the absence of such regulations, with the result that the
amount or timing of the Company's revenues could be adversely affected.
 
  Louisiana State Regulation. The State of Louisiana requires permits for
seismic or drilling operations, drilling bonds, and reports concerning
operations and imposes other requirements relating to the exploration and
production of oil and gas. The State of Louisiana also has statutes or
regulations addressing conservation matters, including provisions for the
unitization or pooling of oil and gas properties, the establishment of maximum
rates of production from wells, and the regulation of spacing, plugging, and
abandonment of such wells.
 
  Offshore Leasing. The Company has acquired and plans to acquire additional
oil and gas leases in the Gulf of Mexico, which will be granted by the Federal
government and administered by the MMS. Such leases are issued through
competitive bidding, contain relatively standardized terms, and require
compliance with detailed MMS regulations and orders pursuant to the Outer
Continental Shelf Lands Act ("OCSLA") (which are subject to change by the
MMS). For offshore operations, lessees must obtain MMS approval for
exploration plans and development and production plans prior to the
commencement of such operations. In addition to permits required from other
agencies such as the Coast Guard, the Army Corps of Engineers, and the
Environmental Protection Agency (the "EPA"), lessees must obtain a permit from
the MMS prior to the commencement of drilling. The MMS has promulgated
regulations requiring offshore production facilities located on the Outer
Continental Shelf to meet stringent engineering and construction
specifications. Similarly, the MMS has promulgated other regulations governing
the plugging and abandoning of wells located offshore and the removal of all
production facilities. With respect to any Company operations conducted on
offshore federal leases, liability may generally be imposed under the OCSLA
for the costs of clean-up and damages caused by pollution resulting from such
operations, other than damages caused by acts of war or the negligence of
third parties. Under certain circumstances, including but not limited to,
conditions deemed a threat or harm to the environment, the MMS may also
require any Company operations on federal leases to be suspended or terminated
in the affected area.
 
  Under the OCSLA, all oil and natural gas pipelines operating on the Outer
Continental Shelf must provide "open and non-discriminatory" access to both
owner and non-owner shippers. Consequently, the Company's gathering and
transportation facilities located on the Outer Continental Shelf must be made
available to third parties.
 
                                      35
<PAGE>
 
  Bonding and Financial Responsibility Requirements. The Company is required
to obtain bonding, or otherwise demonstrate financial responsibility, at
varying levels by governmental agencies in connection with obtaining state or
federal leases or acting as operator on such leases. These bonds may cover
such obligations as plugging and abandonment of unproductive wells, removal of
related production facilities, and pollution liabilities on federal and state
leases. A substantially larger bond than the current $300,000 bond currently
issued on behalf of the Company is required in order to act as operator on
federal offshore leases. The Company will have to satisfy these increased
bonding requirements in the event that it elects to operate any wells on
federal leases. The Company expects to be able to enter into participation
arrangements on its prospects with industry partners who are qualified to act
as operators on Federal leases. In addition, the State of Louisiana recently
adopted financial responsibility requirements with respect to plugging and
abandonment liabilities on Louisiana leases.
 
  Natural Gas Marketing and Transportation. The Federal Energy Regulatory
Commission ("FERC") regulates the transportation and sale for resale of
natural gas in interstate commerce pursuant to the Natural Gas Act of 1938
("NGA") and the Natural Gas Policy Act of 1978 ("NGPA"). In the past, the
Federal government has regulated the prices at which oil and gas could be
sold. Deregulation of wellhead sales in the natural gas industry began with
the enactment of the NGPA in 1978. In 1989, Congress enacted the Natural Gas
Wellhead Decontrol Act (the "Decontrol Act"). The Decontrol Act removed all
NGA and NGPA price and nonprice controls affecting wellhead sales of natural
gas effective January 1, 1993. While sales by producers of natural gas can
currently be made at uncontrolled market prices, Congress could reenact price
controls in the future.
 
  On April 8, 1992, the FERC issued Order No. 636, as amended by Order No.
636-A (issued in August 1992) and Order No. 636-B (issued in November 1992) as
a continuation of its efforts to improve the competitive structure of the
interstate natural gas pipeline industry and maximize the consumer benefits of
a competitive wellhead gas market. The FERC proposed to generally require
interstate pipelines to "unbundle," or separate their traditional merchant
sales services from their transportation and storage services and to provide
comparable transportation and storage services with respect to all gas
supplies whether purchased from the pipeline or from other merchants such as
marketers or producers. The pipelines must now separately state the applicable
rates for each unbundled service (e.g., for natural gas transportation and for
storage). This unbundling process has been implemented through negotiated
settlement in individual pipeline services restructuring proceedings.
 
  On July 16, 1996, the Court of Appeals for the District of Columbia Circuit
("D.C. Circuit") issued its opinion on review of Order No. 636. The opinion
upheld most elements of Order No. 636 including the unbundling of sales and
transportation services, curtailment of pipeline capacity, implementation of
the capacity release program and the mandatory imposition of straight-fixed-
variable ("SFV") rate design for interstate pipeline companies. The D.C.
Circuit did remand certain aspects of Order No. 636 to the FERC for further
explanation including, inter alia, the FERC's decision to exempt pipelines
from sharing in gas supply realignment ("GSR") costs caused by restructuring;
FERC's selection of a twenty-year term matching cap for the right -of-first-
refusal mechanism; the FERC's restriction on the entitlement of no-notice
transportation service to only those customers receiving bundled sales service
at the time of restructuring; and FERC's determination that pipelines should
focus on individual customers, rather than customer classes, in mitigating the
effects of SFV rate design. On February 27, 1997, the FERC issued its order on
remand. The order reaffirmed the holding of Order No. 636 that pipelines
should be entitled to recover 100 percent of their prudently incurred GSR
costs. Moreover, since Order No. 636, few, if any, pipeline customers have
been willing, or required, to commit to twenty-year contracts for existing
capacity. Thus, FERC reduced the contract-matching cap for the right-of-first-
refusal mechanism to five years. In light of the varied post-restructuring
experience with no-notice service, the FERC also decided to no longer limit a
pipeline's no-notice service to its bundled sales customers at the time of
restructuring. Finally, the FERC reaffirmed that pipelines should focus on
individual customers, rather than customer classes, in mitigating the effects
of SFV rate design. Four petitions were filed with the Supreme Court on
January 27, 1997 for writ of certiorari to review those portions of the D.C.
Circuit's opinion which affirmed the capacity release and right-of-first-
refusal provisions adopted in Order No. 636. Those petitions are still pending
before the Court.

  Although the Company is unable to predict the consequences of Order No. 636,
the Company believes that Order No. 636 could have a significant effect on all
segments of the natural gas industry. While Order No. 636 will not directly
regulate the production and sale of gas that may be produced from the
Company's properties, the FERC has stated that the order was intended
primarily to foster increased competition in the natural gas industry and to
allow for the transmission of more accurate price signals. Thus, the order
could affect the market conditions in which the gas is sold and the
availability of transportation services to deliver the gas to market.
 
  Oil Sales and Transportation Rates. The FERC regulates the transportation of
oil in interstate commerce pursuant to the Interstate Commerce Act. Sales of
crude oil, condensate, and gas liquids by the Company are not regulated and
are made at market prices. However, the price a company receives from the sale
of these products is affected by the cost of transporting the products to
market. Effective as of January 1, 1995, the FERC implemented regulations
establishing an indexing system for transportation rates for oil pipelines,
which would generally index such rates to inflation, subject to certain
conditions and limitations. Under the new regulations petroleum pipelines are
able to change their rates within prescribed ceiling levels that are tied to
the Producer Price Index for Finished Goods, minus one percent. Rate increases
made pursuant to the index will be subject to protest, but such protests must
show that the portion of the rate increase resulting from application of the
index is substantially in excess of the pipeline's increase in costs. The new
indexing methodology can be applied to any existing rate, even if the rate is
under investigation. If such rate is subsequently adjusted, the ceiling level
established under the index must be likewise adjusted.
 
  In the order adopting the new regulations the FERC said that as a general
rule pipelines must utilize the indexing methodology to change their rates.
FERC indicated, however, that it was retaining cost-of-service ratemaking,
market-based rates, and settlements as alternatives to the indexing approach.
A cost-of-service proceeding will be instituted to determine just and
reasonable initial rates for new services. A pipeline can also follow a cost-
of-service approach when seeking to increase its rates above index levels for
uncontrollable circumstances. A pipeline can seek to charge market-based rates
if it can establish that it lacks market power. Finally, a pipeline can
establish rates pursuant to settlement if agreed upon by all current shippers.
 
  On May 10, 1996, the D.C. Circuit affirmed the new regulations. The Court
held that by establishing a general indexing methodology along with limited
exceptions to indexed rates, FERC had reasonably balanced its dual
responsibilities of ensuring just and reasonable rates and streamlining
ratemaking through generally applicable procedures. Because of the novelty and
uncertainty surrounding the indexing methodology, as well as the possibility
of the use of cost-of-service ratemaking and market-based rates, the Company
is not able to predict with certainty what effect, if any, these regulations
will have on it. However, other factors being equal, the regulations may tend
to increase transportation costs or reduce wellhead prices for such
commodities.
 
  Environmental. The Company's operations are subject to numerous laws and
regulations governing the discharge of materials into the environment or
otherwise relating to environmental protection. These laws and regulations may
require the acquisition of a permit before drilling commences, restrict the
types, quantities, and concentration of various substances that can be
released into the environment in connection with drilling and production
activities, limit or prohibit drilling activities on certain lands lying
within wilderness, wetlands, and other protected areas, and impose substantial
liabilities for pollution resulting from the Company's operations. Moreover,
the recent trend toward stricter standards in environmental legislation and
regulation is likely to continue. For instance, legislation has been proposed
in Congress from time to time that would reclassify certain oil and gas
exploration and production wastes as "hazardous wastes" which would make the
reclassified wastes subject to much more stringent handling, disposal, and
clean-up requirements. If such legislation were to be enacted, it could have a
significant impact on the operating costs of the Company, as well as the oil
and gas industry in general. State initiatives to further regulate the
disposal of oil and gas wastes are also pending in certain states, and these
various initiatives could have a similar impact on the Company. See "--
Governmental Regulations."
 
  The Comprehensive Environmental Response, Compensation, and Liability Act
("CERCLA"), also known as the "Superfund" law, imposes liability, without
regard to fault or the legality of the original conduct, on
 
                                      37
<PAGE>
 
certain classes of persons that are considered to have contributed to the
release of a "hazardous substance" into the environment. These persons include
the owner or operator of the disposal site or sites where the release occurred
and companies that disposed of or arranged for the disposal of the hazardous
substances found at the site. Persons who are or were responsible for releases
of hazardous substances under CERCLA may be subject to joint and several
liability for the costs of cleaning up the hazardous substances that have been
released into the environment and for damages to natural resources. It is not
uncommon for neighboring landowners and other third parties to file claims for
personal injury and property damage.
 
OPERATIONAL RISKS AND INSURANCE
 
  The drilling of wells is subject to the usual drilling hazards such as
cratering, explosions, uncontrollable flows of oil, gas or well fluids, fires,
pollution, and other environmental risks. The Company's activities are also
subject to perils specific to marine operations, such as capsizing, collision,
and damage or loss from severe weather. These hazards can cause personal
injury and loss of life, severe damage to and destruction of property and
equipment, pollution or environmental damage, and suspension of operations. In
accordance with customary industry practices, the Company maintains insurance
against some, but not all, of such risks and some, but not all, of such
losses. The occurrence of a significant event not fully insured or indemnified
against could materially and adversely affect the Company's financial
condition and operations. Moreover, no assurance can be given that the Company
will be able to maintain adequate insurance in the future at rates it
considers reasonable. See "Risk Factors--Exploration and Operating Risks of
National Gas and Oil Operations."
 
FACILITIES
 
  The Company leases approximately 12,600 square feet of office space in
Houston, Texas under a lease expiring in 1999.
 
EMPLOYEES
   
  As of July 1, 1997, the Company had 25 full-time employees, including three
geologists, eight geophysicists and three landmen. The Company considers its
relations with its employees to be good.

  In 1995, Zydeco Exploration entered into employment agreements with Messrs.
Knecht and McTigue. Each of the agreements provides: (i) for a five year term
ending December 31, 1999 (the "Primary Term"); (ii) that
 
                                      42
<PAGE>
 
Zydeco Exploration may terminate employment with or without cause during the
Primary Term; (iii) for a base salary of $150,000 and $100,000 for Messrs.
Knecht and McTigue, respectively, subject to the Zydeco Exploration Board's
discretion to elect to defer up to 50% of the base salary for not more than
one year; (iv) for the payment of base salary for the entirety of the Primary
Term if the employee is terminated other than for death, disability or for
cause; (v) if terminated for "cause" during the Primary Term, the agreement is
terminated immediately and Zydeco Exploration shall have no further payment
obligations; and (vi) that the employee will retain confidentiality of certain
information and will not compete in the Timbalier Trench or Louisiana
Transition Zone with Zydeco Exploration for a period ending one year after the
expiration of the Primary Term or the termination of the agreement, whichever
occurs first.
 
  Mr. McTigue's agreement also provided for the issuance of certain employee
stock options under the employee stock option plan then in effect for Zydeco
Exploration.
 
  Mr. Knecht's agreement entitles him to receive a 1% overriding royalty
interest in Zydeco Exploration's interest in all oil and gas prospects
generated for Zydeco Exploration by Mr. Knecht. Mr. Knecht relinquished
500,000 shares of Zydeco Exploration Common Stock to Zydeco Exploration in
exchange for the right to receive the overriding royalties under this
agreement.
   
  On July 1, 1997, Zydeco Energy entered into an employment agreement with Dr.
Neidell. Dr. Neidell's agreement provided (i) for a four year term (the
"Neidell Term") ending July 1, 2001; (ii) that Zydeco may terminate employment
with or without cause; (iii) for a base salary of $150,000; (iv) for the
payment of base salary for the entirety of the Neidell Term if he is
terminated other than for death, disability or for cause; (v) that if
terminated for "cause" during the Primary Term, the agreement is terminated
immediately and Zydeco Energy shall have no further payment obligations; and
(vi) that the employee will retain confidentiality of certain information and
will not compete with the Company for one year after termination.     
   
  The Company has not entered into any other employment agreements. The
Company has entered into confidentiality agreements with all of its employees.
    
COMPENSATION OF DIRECTORS
 
  The Company does not compensate its directors, who are executive officers,
for their services other than their compensation as officers and employees of
the Company. The Company pays an annual fee of $12,000, in equal monthly
amounts, to directors who are not executive officers or employees. In 1996 the
Company adopted the 1996 Non-employee Directors Stock Option Plan (the
"Directors Plan"). The Board has granted 15,000 options to each of Messrs.
Tuttle, Bradley and Johnson, pursuant to the Directors Plan. The options
granted vest in one-third increments annually with the first one-third vesting
April 1, 1997. The exercise price of the options granted is $6.69, the average
of the high bid price and low asked price for the Common Stock on the date of
grant.
 
1996 NON-EMPLOYEE DIRECTORS STOCK OPTION PLAN
   
  The Directors Plan was adopted by the Company in 1996. Pursuant to the
Directors Plan, each Non-employee Director is granted an option (a "Director
Option") to purchase 15,000 shares of Common Stock at the average of the
closing bid price and asked price on the date appointed or elected. As of July
1, 1997, three persons were eligible for, and had been granted, Director
Options covering 45,000 shares under the Directors Plan. Each Director Option
that is vested may be exercised in full at one time or in part from time to
time. The exercise price may be paid in cash or shares of Common Stock. Unless
sooner terminated, the Directors Plan will expire on December 31, 2005, and
any Director Option outstanding on such date will remain outstanding until it
has either expired or has been fully exercised.     
 
                                      43
<PAGE>
 
  The Directors Plan provides for adjustments to the maximum number of shares
for which Director Options may be granted, the number of shares subject to
outstanding Director Options and the exercise price of such outstanding
Director Options in the event of a declaration of a stock dividend or any
recapitalization resulting in a stock split-up, combination or exchange of
shares of Common Stock in order to prevent dilution or enlargement of the
rights of optionee. In the event of a "Change in Control," as defined in the
Directors Plan, options granted more than six months prior to the "Change in
Control" will be canceled in exchange for a cash payment equal to the value of
such options.
 
  The Company has filed a registration statement registering the sale of the
shares of Common Stock acquired upon exercise of the Directors Options.
 
EMPLOYEE STOCK OPTIONS
 
  1995 Zydeco Exploration Employee Options. Zydeco Exploration adopted as of
February 22, 1995, the Zydeco 1995 Employee Stock Option Plan (the "1995
Plan"). Pursuant to the 1995 Plan, the Company granted the options summarized
in the table under "1995 Employee Options" on March 3, 1995. These Zydeco
Exploration options (the "1995 Employee Options") were assumed by the Company
pursuant to the Merger.
 
  The following table summarizes the 1995 Employee Options granted by Zydeco
Exploration and which have been assumed by the Company pursuant to the Merger.
The Company did not assume or adopt the Zydeco 1995 Employee Stock Option
Plan.

(1) These amounts represent assumed rates of appreciation in the price of the
    Company's Common Stock during the terms of the options. Actual gains, if
    any, on stock option exercises will depend on the future price of the
    Common Stock and overall stock market conditions. There is no
    representation that the rates of appreciation reflected in this table will
    be achieved.
 
  The exercise price of a 1995 Employee Option may be paid in cash or delivery
of already owned shares of Common Stock having a fair market value equal to
the exercise price. Thirty days prior to certain major corporate events such
as, among other things, certain changes in control, mergers or sales of
substantially all of the assets of Zydeco, each 1995 Employee Option shall
immediately become exercisable in full. All the 1995 Employee Options expire
on March 3, 2005. The number of shares subject to the 1995 Employee Options
and the exercise price of the 1995 Employee Options are subject to adjustment
in the event of a declaration of a stock dividend or any recapitalization
resulting in a stock split-up, combination or exchange of shares of Common
Stock. The shares issuable pursuant to the exercise of the 1995 Employee
Options are registered under the Securities Act of 1933, as amended (the
"Securities Act").
 
  1996 Incentive Equity Plan. In 1996, the Company adopted the 1996 Incentive
Equity Plan (the "1996 Incentive Plan"). The 1996 Incentive Plan provides for
the granting of stock options, stock appreciation rights, phantom shares,
restricted stock, performance units and bonus shares. The aggregate amount of
Common Stock with respect to which awards may be made may not exceed 950,000
shares of Common Stock. The 1996 Incentive Plan is administered by the
Compensation Committee of the Board of Directors (the "Committee"). Subject to
the terms of the 1996 Incentive Plan, the Committee determines to whom
discretionary awards will be made and the terms and conditions of such awards.

the Board, effective on the date of such event. Upon cancellation a
participant would be paid in cash an amount equal to the net value of the
cancelled award.
 
  The Board may make or provide for such adjustments in the numbers of shares

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
  In June 1996, the Company, with the approval of the Board of Directors (Mr.
Sam B. Myers, Jr. abstaining), purchased all the working interest in certain
unproved properties consisting of five non-producing offshore oil and gas
leases from entities (the "Myers Family Interests") owned by the adult
children of the Company's Chief Executive Officer, Mr. Sam B. Myers, Jr., who
subsequently became an officer of certain of the entities. At the time of the
purchase, Mr. Knecht and Mr. Reed were President and Vice President,
respectively, of one of the sellers. The Company paid $302,464 (represented by
the Myers Family Interests as their accumulated cost in the property
interests) for the leases which are located in state waters offshore
Louisiana. The leases are subject to a 7.5% working interest back-in after
payout by the Myers Family Interests. The Myers Family Interests also own an
aggregate of between 4.5% and 7.5% overriding royalty interest in these
leases, which interests were owned by the Myers Family Interests prior to this
transaction with the Company. In addition, Messrs. Knecht and Reed and an
employee of the Company own overriding royalty interests under the leases and
Mr. Knecht received an additional 1.0% overriding royalty interest in three of
the leases pursuant to his employment contract. In addition, at the time of
purchase of the property interests, Messrs. Knecht and Reed also received an
aggregate one-half percent overriding royalty interest in two of the leases
directly from the Myers Family Interests. In May 1996, the Company purchased
certain proprietary geologic and geophysical data and computer equipment which
was being utilized by the Company from a Myers Family Interest for $145,490
(represented by the seller to the Company as the depreciated book value of the
purchased property).
 
  In August 1996, the Company, with the approval of the Board of Directors
(Mr. Sam B. Myers, Jr. abstaining), purchased non-producing leasehold
interests owned by certain Myers Family Interests and agreed to participate
with a Myers Family Interest in the drilling of an exploratory well located in
Timbalier Bay in state waters offshore Louisiana. Mr. Myers was at the time of
the sale, and remains, President of both of the selling entities. The Company
paid $187,500 for a 37.5% working interest in the drilling prospect. The Myers
Family Interests own an aggregate of between 33.1% and 37.3% net revenue
interest in the prospect leases and Mr. Myers owns an approximate 1.6%
overriding royalty interest under portions of the leases. The Myers Family
Interests participated in the well with a working interest of 41.2% and paid
their proportionate share of the estimated cost of drilling and well
completion. The Myers Family Interests can also back-in for a 25.0% working
interest of a well after payout. In addition, an affiliate of a director of
the Company also purchased a 5.0% working interest in the properties on the
same basis as the terms of the Company's participation. Messrs. Knecht and
 
                                      46
<PAGE>
 
Reed also own net revenue interests in the prospect leases, one of which also
purchased an additional 1% working interest participation in the property at
the same time and on the same basis as the terms of the Company's
participation. Drilling of the exploratory well commenced in August 1996 and
was abandoned in September 1996 for mechanical reasons without testing the
well's primary objectives. The Company has undertaken to sell a portion or
farmout its interest in this prospect and at December 31, 1996, reflected
$187,500 in unproved and unevaluated properties related to the prospect. The
Company charged $647,355 to exploration expense in 1996 in connection with the
drilling and abandonment of the well.
 
  In 1996, the Company licensed software and purchased related software
maintenance services aggregating $325,768 from a subsidiary of GeoScience
Corporation. Subsequently, in October 1996, Mr. Prince became a director of
GeoScience Corporation.
   
  In connection with the acquisition of Wavefield, the Company agreed to lease
certain office furniture and equipment owned by Dr. Neidell which was and is
used by Wavefield.     
   
  Dr. Neidell is a director of MMS Petroleum PLC, a licensee of the Wavefield
Imaging Technology. The license was negotiated and executed prior to the
Company's acquisition of Wavefield.     
 
  The Company believes all of the transactions with related parties have been
on terms no less favorable to the Company than those terms which may have been
obtained from unrelated third parties.
 
  None of the officers or directors of the Company is related to any other
executive officer or director of the Company.
 
CONFLICTS OF INTEREST
 
  Certain of the Company's officers, directors, employees and stockholders own
working and overriding royalty interests in leases owned by the Company or that
adjoin, or are in the vicinity of, some of the potential prospects described
herein. Such officers, directors, employees and stockholders will continue to
conduct operations on such leases, including, without limitation, acquiring or
shooting, processing and/or reprocessing seismic data, remediating or
recompleting existing wells and/or the drilling of new wells. Hence, a conflict
of interest may exist if the Company proposes to drill or farmout for the
drilling of a well or wells upon leases it currently owns and leases
immediately offsetting the leases owned by its officers, directors, employees
or stockholders.
 
  Certain members of the Company's management team are also investors,
executive officers and/or directors of small privately owned companies with
limited oil and gas operations. Though the Company's management team intends to
devote their full time to managing the affairs of the Company, they may
occasionally devote a minimal amount of time to other positions they hold.
Company transactions with related parties have been and will be subject to the
approval of the independent directors. See "Risk Factors--Conflicts of
Interest."

                    DESCRIPTION OF THE COMPANY'S SECURITIES
 
GENERAL
   
  The Company is authorized to issue 50,000,000 shares of Common Stock, par
value $.001 per share, and 1,000,000 shares of Preferred Stock, par value
$.001 per share. As of the date of this Prospectus, 6,707,098 shares of Common
Stock are outstanding, and such shares are owned by approximately 56 persons
of record and are owned beneficially by approximately 750 persons. As of the
date of this Prospectus, there are no shares of Preferred Stock outstanding.
    
COMMON STOCK
 
  The holders of shares of Common Stock are entitled to one vote for each
share held of record on all matters to be voted on by stockholders. There is
no cumulative voting with respect to the election of directors, with the
result that the holders of more than 50% of the shares voting for the election
of directors can elect all of the directors then being elected. The holders of
shares of Common Stock are entitled to receive dividends when, as and if
declared by the Board of Directors out of funds legally available therefor. In
the event of liquidation, dissolution or winding up of the Company, the
holders of shares of Common Stock are entitled to share ratably in all assets
remaining available for distribution to them after payment of liabilities and
after provision has been made for each class of stock, if any, having
preference over the shares of Common Stock. Holders of shares of Common Stock,
as such, have no conversion, redemption, preemptive or other subscription
rights. All of the outstanding shares of Common Stock and the shares of Common
Stock included in the Units, described below, are fully paid and
nonassessable.
 
PREFERRED STOCK
 
  The Company's Certificate of Incorporation authorizes the issuance of
1,000,000 shares of Preferred Stock with such designations, rights and
preferences as may be determined from time to time by the Board of Directors.
Accordingly, the Board of Directors is empowered, without stockholder
approval, to issue shares of Preferred Stock with dividend, liquidation,
conversion, voting or other rights which could adversely affect the voting
power or other rights of the holders of shares of Common Stock. In addition,
the shares of Preferred Stock could be utilized, under certain circumstances,
as a method of discouraging, delaying or preventing a change in control of the
Company. In July 1996, all 781,255 shares of Preferred Stock then outstanding
were converted into 781,255 shares of Common Stock. There are no shares of
Preferred Stock currently outstanding.
 
REDEEMABLE COMMON STOCK PURCHASE WARRANTS
 
  Each Redeemable Common Stock Purchase Warrant (a "Redeemable Warrant")
entitles the registered holder to purchase one share of Common Stock for
$5.50, subject to adjustment in certain circumstances. The Redeemable Warrants
expire on December 13, 2000. The Company may call the Redeemable Warrants for
redemption, in whole and not in part, at a price of $.01 per Redeemable
Warrant at any time if the last sale price of the shares of Common Stock has
been at least $10.00 per share for the 20 consecutive trading days ending on
the third day prior to the date on which the notice of redemption is given.
The notice of redemption must be given at least 30 days in advance of the
redemption date. The holders of Redeemable Warrants have exercise rights until
the close of business on the redemption date.
 
  The exercise price, number of shares of Common Stock issuable on exercise of
the Redeemable Warrants and redemption price are subject to adjustment in
certain circumstances including in the event of a stock dividend,
recapitalization, reorganization, merger or consolidation of the Company.
However, the Redeemable Warrants are not subject to adjustment for issuances
of shares of Common Stock at a price below their exercise price.
 
  The Company has the right, in its sole discretion, to decrease the exercise
price of the Redeemable Warrants for a period of not less than 30 days on not
less than 30 days prior written notice to the warrant holders. In addition,

the Company has the right, in its sole discretion, to extend the expiration
date of the Redeemable Warrants on five business days prior written notice to
the holders of the Redeemable Warrants.
 
  The Redeemable Warrants are quoted on the Nasdaq SmallCap Market. As of the
date of this Prospectus there are 3,300,000 Redeemable Warrants outstanding.
 
UNIT OPTIONS
 
  The Company's Unit Options are currently exercisable at $6.60 per Unit. Each
Unit consists of one share of Common Stock and two Common Stock Purchase
Warrants ("Unit Option Warrants"). Each Unit Option Warrant will entitle the
holder to purchase one share of Common Stock under terms similar to the terms
of the Redeemable Warrants except that the Unit Option Warrants are not
redeemable. The exercise price of the Unit Options and the number of Units
issuable upon exercise of a Unit Option are subject to adjustment in the event
Common Stock (or warrants, options or convertible securities exercisable or
convertible into Common Stock) (including the Shares offered hereby) are
issued at less than either the Unit Option exercise price or trading price of
the Common Stock. The holders of Unit Options may elect to convert Unit
Options into a number of Units equal to the difference between the trading
price of Common Stock and the then current Unit Option exercise price, divided
by the exercise price. The result of the foregoing provisions is that the
number of Unit Options will adjust upward and the related exercise price will
adjust downward in the event the Shares are sold in the Offering at a Price to
the Public of less than $6.60 per share. The foregoing provisions could, under
certain circumstances, afford the holders of the Unit Options the opportunity
to purchase a substantial amount of the Company's securities at a price
significantly below market. The holders of Unit Options are entitled to demand
and piggyback registration rights with respect to the Unit Options and all
underlying securities. The demand registration rights expire December 13, 1998
and the piggyback registration rights expire on December 13, 2000. As of the
date of this Prospectus there were 150,000 Unit Options outstanding.
 
1995 BRIDGE WARRANTS
 
  In connection with certain private financing, the Company issued a total of
225,028 warrants (the "1995 Bridge Warrants") to certain persons. The terms
and conditions of the 1995 Bridge Warrants are substantially the same as the
terms and conditions of the $5.50 Warrants except as described in this
paragraph. The exercise price for the 1995 Bridge Warrants is $5.33 per share,
and they include a "cashless" exercise right pursuant to which 1995 Bridge
Warrants may be surrendered in order to pay the exercise price on other 1995
Bridge Warrants. In addition, the 1995 Bridge Warrants may not be redeemed by
the Company. The 1995 Bridge Warrants were not registered with the Securities
and Exchange Commission (the "Commission"). One of the Underwriters owns
75,000 of the 1995 Bridge Warrants.
 
ZYDECO EXPLORATION WARRANTS
 
  Certain Company warrants (the "Zydeco Exploration Warrants") were issued by
Zydeco Exploration, Inc. prior to the Merger with TN Energy and assumed by the
Company in connection with the Merger. Each Zydeco Exploration Warrant
entitles the registered holder to purchase one share of Common Stock for
$1.60, subject to adjustment in certain circumstances, at any time ending on
December 1, 1999, at which time the Warrants will expire. The Zydeco
Exploration Warrants are not redeemable.
 
  The exercise price and the number of shares of Common Stock issuable on
exercise of the Zydeco Exploration Warrants are subject to adjustment in
certain circumstances including in the event of a stock dividend,
recapitalization, reorganization, merger or consolidation of the Company. The
exercise price may be paid in cash or with shares of Common Stock. The holders
of Zydeco Exploration Warrants do not have the rights or privileges of holders
of shares of Common Stock prior to the exercise of the Zydeco Exploration
Warrants.
 
  The Company has registered the resale of the shares of Common Stock issuable
upon exercise of the Zydeco Exploration Warrants with the Commission. As of
the date of this Prospectus there were 30,640 Zydeco Exploration Warrants
outstanding.

</TABLE>
 
  Upon the terms and subject to the conditions of the Underwriting Agreement,
the Company is obligated to sell, and the Underwriters are obligated to
purchase, all of the Common Shares set forth in the above table if any of the
Common Shares are purchased.
 
  The Underwriters propose to offer the Shares to the public initially at the
public offering price set forth on the cover page of this Prospectus, and to
selected dealers at such public offering price less a concession not to exceed
$       per share. The Underwriters or such dealers may reallow a commission
to certain other dealers not to exceed $     per share. After the Offering to
the public, the offering price, the concession to selected dealers and the
reallowance to other dealers may be changed by the Representative.
 
  The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to 300,000 additional
Shares to cover over-allotment, if any, at the public offering price, less
underwriting discounts and commissions, as set forth on the cover page of this
Prospectus. If the Underwriters exercise this option, then each of the
Underwriters will have a firm commitment, subject to certain conditions, to
purchase a number of option shares proportionate to such Underwriters' initial
commitment as indicated in the table above. The Underwriters may exercise such
option only to cover over-allotments made in connection with the sale of the
Shares offered hereby.
   
  The Company, its officers and directors and certain stockholders (who
beneficially hold in the aggregate 4,361,470 shares of Common Stock) have
agreed not to sell, offer to sell, issue, distribute or otherwise dispose of
any shares of Common Stock of the Company for a period of 180 days from the
date of this Prospectus (subject to certain limited exceptions) without the
prior written consent of the Representative.     
 
  The Company has agreed to reimburse the Underwriters for up to $150,000 of
the Underwriters' out-of-pocket expenses (including fees of their counsel) in
connection with the sale of the Shares offered hereby. The Company has also
agreed to indemnify the Underwriters or contribute to losses arising out of
certain liabilities that may be incurred in connection with this Offering,
including liabilities under the Securities Act.
 
  In connection with this Offering, certain Underwriters may engage in passive
market making transactions in the Common Stock on the Nasdaq SmallCap Market
immediately prior to the commencement of sales in this Offering, in accordance
with Rule 103 of Regulation M. Passive market making consists of displaying
bids on the Nasdaq SmallCap Market limited by the bid prices of independent
market makers and purchases limited by such prices and effected in response to
order flow. Net purchases by a passive market maker on each day are limited to
a specified percentage of the passive market maker's average daily trading
volume in the Common Stock during a specified period and must be discontinued
when such limit is reached. Passive market making
 
                                      51
<PAGE>
 
may stabilize the market price of the Common Stock at a level above that which
might otherwise prevail and, if commenced, may be discontinued at any time.
 
  In connection with this offering, the Underwriters may engage in
stabilizing, syndicate short covering transactions, penalty bids or other
transactions during the offering that may stabilize, maintain or otherwise
affect the market price of the Common Stock at a level above that which might
otherwise prevail in the open market. Stabilizing transactions are bids for
and purchases of the Common Stock for the purpose of preventing or retarding a
decline in the market price of the Common Stock to facilitate the Offering.
Syndicate short covering transactions are bids to purchase and actual
purchases of Common Stock on behalf of the Underwriters to provide them with
enough Common Stock to deliver to those purchasing Common Stock in the
Offering. A penalty bid is an arrangement that permits the Representative to
reclaim a selling concession when the Common Stock originally sold by the
syndicate member are purchased in a syndicate covering transaction. Such
stabilizing, syndicate short covering transactions, penalty bids and other
transactions, if commenced, may be discontinued at any time.

                             CHANGE OF ACCOUNTANTS
 
  On January 17, 1996, the Company advised BDO Seidman, LLP that its services
would no longer be required as independent accountants for auditing the annual
financial statements of the Company. As a result of the Merger of the Company
with Zydeco Exploration, the historical financial statements of Zydeco
Exploration became the financial statements of the Company. Arthur Andersen
LLP were the independent accountants for Zydeco Exploration prior to the
Merger and became the independent accountants of the Company commencing with
the audit of the Company's consolidated financial statements for the year
ended December 31, 1995. During the two most recent fiscal years prior to
January 17, 1996, there were no disagreements with BDO Seidman, LLP on any
matter of accounting principles or practices, financial statement disclosure,
auditing scope or procedure, or any reportable events. The report of BDO
Seidman, LLP for fiscal years 1993 and 1994 contained no adverse opinion or
disclaimer of opinion and was not qualified or modified as to uncertainty,
audit scope or accounting principles.
 
  BDO Seidman, LLP, at the request of the Company, furnished a letter
addressed to the Commission stating their agreement with the above statements.
A copy of the BDO Seidman letter to the Commission, dated January 19, 1996,
was filed as Exhibit 16.1 to the Company's Form 8-K, dated January 22, 1996.

                      GLOSSARY OF CERTAIN INDUSTRY TERMS
 
  The definitions set forth below shall apply to the indicated terms as used
in this Prospectus. All volumes of natural gas referred to herein are stated
at the legal pressure base of the state or area where the reserves exist and
at 60 degrees Fahrenheit and in most instances are rounded to the nearest
major multiple.
 
  Area of Mutual Interest. An area designated by exploration contract or other
oil and gas agreement in which the contract parties have mutual and exclusive
rights to conduct exploration and development for oil and gas.
 
  2-D Seismic. The method by which a cross-section of the earth's subsurface
is created through the processing of reflected seismic data collected along a
single source profile.
 
  3-D Seismic. The method by which a three dimensional image of the earth's
subsurface is created through the processing of reflected seismic data
collected over surface grid. 3-D seismic surveys allow for a more detailed
understanding of the subsurface than do 2-D seismic surveys and contribute
significantly to field appraisal, development and production.
 
  Back-in Interest. A portion of an economic interest in an oil and gas lease
that may be returned to its former owner after a predetermined amount of
production or income has been produced.
 
  Bbl. One stock tank barrel, or 42 U.S. gallons liquid volume, used herein in
reference to crude oil or other liquid hydrocarbons.
 
  CAEX. Computer aided exploration for oil and gas.
 
  Completion. The installation of permanent equipment for the production of
oil or gas, or in the case of a dry hole, the reporting of abandonment to the
appropriate agency.
 
  Common Depth Point stacking or CDP. A method of improving the signal quality
of seismic data by adding or "stacking" the seismic traces which have a common
midpoint between each source and receiver after time-correcting the data for
the offset or distance between the sources and receivers.
 
  Dip-Moveout or DMO. A process to correct CDP data so that dipping events
will stack or focus better using a common velocity.
 
  Discounted Present Value. A method of determining the present value of
proved reserves in accordance with Commission requirements. Under the
Commission method, the future net revenues before income taxes from proved
reserves are estimated assuming that oil and natural gas prices and production
costs remain constant. The resulting stream of revenues is then discounted at
the rate of 10% per year to obtain the present value.
 
  Dry hole or well. A well found to be incapable of producing hydrocarbons in
sufficient quantities such that proceeds from the sale of such production
exceed production expenses and taxes.
 
  Exploratory well. A well drilled to find and produce oil or gas reserves not
classified as proved, to find a new reservoir in a field previously found to
be productive of oil or gas in another reservoir, or to extend a known
reservoir.
 
  Farmout. An agreement whereunder the owner of a working interest in an oil
and gas lease assigns the working interest or a portion thereof to another
party who desires to drill on the leased acreage. Generally, the assignee is
required to drill one or more wells in order to earn its interest in the
acreage. The assignor usually retains a royalty or reversionary interest in
the lease. The interest transferred by the assignor is a "farmout."
 
  Field. An area consisting of a single reservoir or multiple reservoirs all
grouped on or related to the same individual geological structural feature
and/or stratigraphic condition.

property.     
 
  Nonoperating Interest. An interest in a well which does not include the
responsibility for the development and operation of the well.
 
  Operating Interest. An interest in a well which includes responsibility for
the development and operation of the well.
 
  MBbls. One thousand barrels of crude oil or other liquid hydrocarbons.
 
  Mcf. One thousand cubic feet of natural gas.
 
  Mcf/d. One thousand cubic feet of natural gas per day.
 
  Mcfe. One thousand cubic feet equivalent, determined using the ratio of six
Mcf of natural gas to one Bbl of crude oil, condensate or natural gas liquids.
 
  Migration. An imaging process that "relocates" seismic events to account for
changes in the dip of the underlying strata.
 
  Net acres or net wells. The sum of the fractional working interests owned in
gross acres or gross wells.
 
  Pay or Pay Zone. An industry term used to describe reservoirs in the
subsurface which contain hydrocarbons.

have been "stacked."
 
  Present Value. When used with respect to oil and gas reserves, the estimated
future gross revenue to be generated from the production of proved reserves,
net of estimated production and future development costs, using prices and
costs in effect as of the date indicated, without giving effect to non-
property related expenses such as general and administrative expenses, debt
service and future income tax expense or to depreciation, depletion and
amortization, discounted using an annual discount rate of 10%.
 
  Prestack Migration. Migration applied to individual seismic traces prior to
"stacking."
 
  Productive Well. A well that is found to be capable of producing
hydrocarbons in sufficient quantities such that proceeds from the sale of such
production exceed production expenses and taxes.
 
  Proved developed producing reserves. Proved developed reserves that are
expected to be recovered from completion intervals currently open in existing
wells and able to produce to market.
 
  Proved developed reserves. Proved reserves that can be expected to be
recovered from existing wells with existing equipment and operating methods.

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
TO THE STOCKHOLDERS AND THE BOARD OF DIRECTORS OF ZYDECO ENERGY, INC.:
 
  We have audited the accompanying consolidated balance sheets of Zydeco
Energy, Inc. (a Delaware corporation) and subsidiary as of December 31, 1996,
and 1995, and the related consolidated statements of operations, stockholders'
equity and cash flows for the years then ended and the period from inception
(March 17, 1994) through December 31, 1994. 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 audit 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 Zydeco Energy, Inc. and
subsidiary as of December 31, 1996 and 1995, and the results of its operations
and its cash flows for the years ended December 31, 1996, and 1995, and the
period from inception (March 17, 1994) through December 31, 1994, in
conformity with generally accepted accounting principles.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES.
 
  Organization. Zydeco Energy, Inc. was incorporated in Delaware in June 1993,
as a "special purpose acquisition corporation" under the name TN Energy
Services Acquisition Corp. ("TN Energy"), for the purpose of raising funds and
acquiring an operating business engaged in the energy services industry. Other
than its efforts to acquire an energy services business, TN Energy did not
engage in any business activities prior to December 1995. On December 20,
1995, the Company acquired all the outstanding common stock and preferred
stock of Zydeco Exploration, Inc. ("Zydeco") pursuant to a merger (the "TN
Acquisition") and changed its name to Zydeco Energy, Inc. As used herein,
unless the context indicates otherwise, the term "Company" refers to Zydeco
Energy, Inc. and Zydeco, its wholly-owned subsidiary. See "Note 3--Reverse
Acquisition by Zydeco".
 
  The Company is engaged in identifying drilling prospects, acquiring leases,
drilling, and producing reserves from those properties and utilizing focused
geologic concepts and advanced 3D seismic technology. In addition to utilizing
advanced 3D seismic technology to evaluate and analyze prospects for the
Company, the Company performs advanced geophysical seismic analysis services
for third parties, principally for its exploration partners. The Company's
current focus is to explore for oil and gas in the Louisiana Transition Zone,
the region of land and shallow waters within a few miles of the shoreline. The
Company's future operations are dependent upon a variety of factors,
including, but not limited to, successful application of 3D seismic evaluation
and interpretation expertise in developing oil and gas prospects, future
generation of 3D seismic analysis fees, profitable exploitation of future
prospects, and the Company's ability to access capital sources necessary for
continued growth.
 
 Significant Accounting Policies
 
  Basis of Presentation. For accounting purposes the TN Acquisition has been
treated as a recapitalization of Zydeco with Zydeco as the acquiror (reverse
acquisition). Accordingly, the historical financial statements prior to
December 20, 1995, are those of Zydeco. The consolidated financial statements
at December 31, 1996, and 1995, include the accounts of the Company and Zydeco
Exploration, Inc., the wholly-owned subsidiary of the Company. All significant
intercompany transactions have been eliminated in consolidation.
   
  In connection with the Company's two exploration agreements (See "Note 2--
Exploration Agreements"), advances to the Company are treated as exploration
obligations and expenditures made by the Company pursuant to the exploration
agreements are charged against the related exploration obligation. No costs or
expenses incurred pursuant to the exploration agreements are recognized by the
Company until the Company, pursuant to the terms of the exploration
agreements, begins sharing in such costs.     
 
  Cash and Cash Equivalents. The Company considers all highly liquid
investments purchased with original maturities of three months or less to be
cash equivalents.
   
  Marketable Securities. The Company's investments in marketable securities
primarily consisted of short-term U. S. Treasury bills at December 31, 1996,
and short-term investments in federal agency obligations under guaranteed bank
repurchase agreements at December 31, 1995. As the Company's investments in
marketable securities are all short-term in nature, their carrying values at
December 31, 1996 and 1995 approximate fair value. Such investments are
classified as trading securities since they are generally invested for periods
of thirty days or less with no intent of holding to maturity. As a result of
their short-term nature, any unrealized gains or losses are not significant.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
  Oil and Gas Properties. The Company accounts for its oil and gas exploration
and production activities using the successful efforts method of accounting.
Under this method, acquisition costs for proved and unproved properties are
capitalized when incurred. Exploration costs, including geological and
geophysical costs and the costs of carrying and retaining unproved properties,
are expensed. Exploratory drilling costs are initially capitalized, but
charged to expense if and when the well is determined not to have found proved
reserves. Costs of productive wells, developmental dry holes and productive
leases are capitalized and amortized on a property-by-property basis using the
unit-of-production method. The estimated costs of future plugging,
abandonment, restoration and dismantlement are considered as a component of
the calculation of depreciation, depletion, and amortization. Unproved
properties with significant acquisition costs are assessed periodically on a
property-by-property basis and any impairment in value is charged to expense.
 
  Equipment. Hardware and software associated with the 3D seismic technology
equipment, office furniture, and leasehold improvements are recorded at cost,
and the related depreciation is calculated on a straight-line basis over the
estimated useful lives of the assets, which range from 2 to 7 years.
 
  Impairment of Long-Lived Assets. The Company elected to adopt Statement of
Financial Accounting Standards (SFAS) No. 121 "Accounting for the Impairment
of Long-Lived Assets and for Long-Lived Assets to be Disposed of" effective in
1994. Management reviews its long-lived assets (i.e., oil and gas properties
and equipment) whenever events or changes in circumstances indicate that the
carrying amounts of such assets may not be recoverable. If the carrying
amounts of any of the Company's oil and gas properties or equipment are
greater than their projected undiscounted future cash flows, an impairment
loss to adjust the properties or equipment to fair value is recognized.
Through December 31, 1996, no such provision for impairment was necessary.
This determination of future cash flows from proved properties is based on
current proved oil and gas reserve estimates and current oil and gas prices
and costs. Management's estimates of fair value also reflect a discount factor
on future cash flows consistent with the rate used by the Company in other
fair-value determinations.
 
  Income Taxes. The Company accounts for income taxes under SFAS No. 109 which
requires the asset and liability approach to accounting for income taxes.
Under this approach, deferred income taxes are determined based upon
differences between the financial statement and tax bases of the Company's
assets and liabilities and operating loss carryforwards using enacted tax
rates in effect for the years in which the differences are expected to
reverse. Deferred tax assets are recognized if it is more likely than not that
the future tax benefit will be realized.
 
  Oil and Gas Revenues. Oil and gas revenues are recorded using the
entitlements method of accounting, whereby the Company recognizes oil and gas
revenues as their entitlement share is produced. Individually and in the
aggregate, the Company has no material gas imbalances as of December 31, 1996.
 
  Seismic Service Revenues. Seismic service revenues are recognized as
services are performed.
   
  Earnings Per Share. Earnings per share of common stock and common stock
equivalent (primary earnings per share) is based on the weighted average
number of shares of common stock and common stock equivalents outstanding
during the period. The common stock options, common stock warrants, and
convertible preferred stock are common stock equivalents but were anti-
dilutive in all periods presented.     
 
  In February 1997, the Financial Accounting Standards Board (FASB) issued
Statement of Financial Accounting Standards (SFAS) No. 128--"Earnings per
Share" effective for interim and annual periods after December 15, 1997. This
statement replaces primary earnings per share ("EPS") with a newly defined
basic EPS and modifies the computation of diluted EPS. The Company's basic and
diluted EPS computed using the requirements of SFAS 128, are the same as the
currently disclosed primary EPS.
 
  Treasury Stock. Treasury stock is recorded at cost and represents the value
of 781,255 common shares purchased in January 1995, from an officer of the
Company in consideration for an overriding royalty interest in certain
properties in which the Company had an interest at the time of the treasury
stock purchase. The Company

                      ZYDECO ENERGY, INC. AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
had no proved reserves at the time of the transaction. The cost of treasury
stock of $7,252 was determined on the basis of a pro-rata allocation of the
Company's accumulated cost in unproved properties at the time of the
transaction in comparison to the net revenue interest transferred.
 
  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 revenues and expenses during the
reporting period. Actual results could differ from those estimates.
Significant estimates with regard to these financial statements include the
estimate of proved oil and gas reserve volumes and the related discounted
future net cash flows therefrom. See "Supplemental Information on Oil and Gas
Producing Activities".
 
  Reclassifications. Certain reclassifications of prior period amounts have
been made to conform with current year presentation.
 
  Unaudited Interim Financial Information. The consolidated financial
statements for the three months ended March 31, 1997 and 1996 included herein
have been prepared by the Company without audit pursuant to the rules and
regulations of the Securities and Exchange Commission. Accordingly, these
statements reflect all adjustments (consisting only of normal recurring
entries) which are, in the opinion of management, necessary for a fair
statement of the financial results for the interim periods. Certain
information and notes normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed
or omitted pursuant to such rules and regulations, although management
believes that the disclosures are adequate to make the information presented
not misleading. Interim period results are not necessarily indicative of the
results to be achieved for an entire year.
 
2. EXPLORATION AGREEMENTS.
 
  Fortune Exploration Agreement--In February 1995, Zydeco entered into an
Exploration Agreement (the "Fortune Agreement") with a predecessor of Fortune
Petroleum Corporation ("Fortune"). Under the Fortune Agreement, Fortune
advanced $4.8 million in a series of payments to purchase a 50% interest in
certain potential prospects ("Prospects") owned by the Company and to fund the
initial development of the potential Prospects. Pursuant to the Fortune
Agreement, $628,547 represented a reimbursement of certain of the costs
previously incurred by the Company on the potential Prospects. The remaining
funds are designated for all third-party costs of preparing the potential
Prospects for evaluation, including lease acquisition, lease maintenance, and
the acquisition, processing and interpretation of seismic data. Thereafter,
the Fortune Agreement provides that the parties shall bear any additional
costs equally. At December 31, 1996, and 1995, the portion not yet expended is
recorded as an exploration obligation and classified as a current liability.
Future expenditures incurred on Prospect leads will be charged against the
obligation. No expenditures incurred pursuant to the Fortune Agreement will be
recognized by the Company until the parties begin sharing equally in such
costs, if any. At December 31, 1996, inception-to-date expenditures under the
Fortune Agreement aggregated approximately $2,352,770, net of interest earned
of $161,758 and revenue from farmout of interests of $66,319. Inception-to-
date expenditures through March 31, 1997, aggregated $2,393,498 (unaudited)
net of interest earned of $185,279 (unaudited).
 
  The Fortune Agreement provides that the Company may, at its option, perform
seismic data or well log processing on the Prospects utilizing its own
facilities rather than engaging third parties. Revenues related to in-house
processing of the Prospects were $31,500 and $100,000 for the years ended
December 31, 1996, and 1995, respectively.
 
  Cheniere Exploration Agreement--In April 1996, the Company executed an
Exploration Agreement (the "Cheniere Agreement") with Cheniere Energy
Operating Co., Inc. ("Cheniere") covering an area of land and waters in
western Cameron Parish, Louisiana ("West Cameron Seismic Project"). The
Cheniere Agreement
 
                                      F-9
<PAGE>
 
                      ZYDECO ENERGY, INC. AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
provides for aggregate payments to Zydeco of $13.5 million to fund the costs
of seismic acquisition, including the purchase of seismic rights or lease
options on the related onshore acreage of the West Cameron Seismic Project,
and to complete data acquisition and processing of a 3D seismic survey of the
onshore and offshore areas. The Cheniere Agreement, as amended, provides that
Cheniere may receive up to a 50% interest in the West Cameron Seismic Project
and in any leases acquired as a result thereof through May 2001, based on
Cheniere completing its funding of the entire $13.5 million. The Cheniere
Agreement provides that Cheniere may discontinue funding at any time and its
interest would then be reduced pro rata based on the West Cameron Seismic
Project's total cost. Seismic operations commenced in August 1996. At December
31, 1996, the Company had incurred costs of approximately $5,806,113 in
connection with the West Cameron Seismic Project net of interest earned of
$31,067 on the unused project funds. Inception-to-date expenditures through
March 31, 1997, aggregated $7,171,605 (unaudited) net of interest earned of
$41,471 (unaudited). As amended, the Cheniere Agreement provides for the
remaining payments to be paid by Cheniere consistent with the Company's
current expectations of the timing of costs to be incurred on the Project. At
December 31, 1996, Cheniere had advanced $6 million under the Cheniere
Agreement.
 
  Each of the above exploration agreements contains provisions whereby either
party to the agreement has the right to "farmout" a portion or all of its
interest in a prospect under a put arrangement. In the event of such a
farmout, the farmor would retain a two percent of eight eighths overriding
royalty interest in the project, convertible into a 20% of eight eighths
working interest after the other party recouped its drilling, completion, and
hook-up costs of the well from production. Should either party farmout a
smaller working interest, the overriding royalty and after-payout working
interests would be proportionately reduced.
 
3. REVERSE ACQUISITION BY ZYDECO.
 
  On December 20, 1995, the shareholders of TN Energy approved a merger with
Zydeco ("the Merger"). Pursuant to the Merger Agreement, each outstanding
share of common stock of Zydeco, par value $.000333 per share, was converted
into the right to receive 1.56251 shares of Common Stock of TN Energy, par
value $.001 per share; each share of convertible preferred stock of Zydeco,
par value $5.00 per share, was converted into the right to receive 1.56251
shares of Convertible Preferred Stock of TN Energy, par value $.001 per share,
and any fractional shares settled in cash.
 
  In addition, TN Energy assumed Zydeco's existing stock options issued in
connection with Zydeco's 1995 Employee Stock Option Plan (the "Plan"),
substituting shares of Common Stock of TN Energy as the shares subject to
purchase under the Plan. Further, TN Energy assumed each existing common stock
warrant issued by Zydeco, substituting Common Stock of TN Energy as the shares
subject to purchase under the warrants. The number of shares subject to
purchase under option and warrant agreements was adjusted by multiplying the
number of Zydeco option or warrant shares by the exchange ratio of 1.56251
shares. The exercise prices for Zydeco options and warrants were adjusted by
dividing the stated exercise price by the exchange ratio. After completion of
the Merger, TN Energy changed its name to Zydeco Energy, Inc. At the
conclusion of the Merger on December 21, 1995, Zydeco Energy, Inc. had
5,781,275 shares of Common Stock outstanding and 781,255 shares of Convertible
Preferred Stock outstanding.
   
  The Merger was treated as a reverse acquisition for accounting purposes with
Zydeco as the acquiror and TN Energy as the acquiree based upon Zydeco's then
current officers and directors assuming management control of the resulting
entity and the value and ownership interest being received by current Zydeco
stockholders exceeding that received by TN Energy stockholders. The Merger,
for accounting purposes, was treated as if Zydeco issued additional capital
stock to TN Energy shareholders for cash. The net assets of TN Energy on the
date of the Merger were $7,971,525 and, accordingly, the shares of common
stock of TN Energy on such date were recorded as an increase in common stock
and additional paid-in capital. The costs incurred in connection with the
Merger of approximately $669,700 were charged to additional paid-in capital at
December 31, 1995.

  As of December 31, 1996, the Company had a net operating loss carryforward
for federal income tax purposes approximately equal to the accumulated deficit
recognized for book purposes, which will be available to reduce future taxable
income. The full realization of the tax benefit associated with the
carryforward depends predominantly upon the Company's ability to generate
taxable income during the carryforward period. Because of the current
uncertainty of realizing such tax asset in the future, a valuation allowance
has been recorded equal to the amount of the net deferred tax asset, which
caused the Company's effective tax rate to differ from the statutory income
tax rate. The net operating loss carryforward, if not utilized, will begin to
expire in the year 2009.
 
5. INDEBTEDNESS.
 
  Long-term Obligations. Balances of the Company's long-term obligations at
December 31, 1996 and 1995 consist of the following:

  Capital Lease--Computer Hardware. Amortization is calculated on a three-
year, straight-line basis and aggregated $316,747 as of December 31, 1996.
This lease has a stated interest rate of 19.45%. The lease is collateralized
by the computer equipment utilized under the lease.
 
  Bridge Financing. In connection with the Merger, TN Energy entered into a
financing arrangement ("Bridge Financing") and ultimately borrowed $225,028
from three investors ("Bridge Lenders") to finance TN Energy's share of legal,
accounting, and printing costs of the Merger. The notes, including accrued
interest at 10%, were repaid in January 1996. In December 1995, in connection
with arranging the Bridge Financing, the Company issued to the Bridge Lenders
warrants to purchase 225,028 shares of Common Stock ("Non-Redeemable Bridge
Warrants") at a purchase price of $5.33 per share. See "Note 6--Convertible
Preferred Stock, Common Stock, and Warrants".
 
  In addition, options to purchase 225,000 outstanding shares of the Company
were granted in December 1995, by certain stockholders of the Company. The
options were granted by the stockholders for 150,000 shares to the Bridge
Lenders as an inducement to make the Bridge Financing and for 75,000 shares to
other Principals in connection with discussions with TN Energy that resulted
in the introduction of Zydeco. The aggregate

exercise price for all the options granted was approximately $30. The cost of
such options was reflected as a financing expense and capital contribution,
respectively, by the Company prior to the Merger.
 
  Maturities. The Company's existing indebtedness matures in 1997. The
aggregate amount of the remaining lease payments for the Company's capital
lease obligation discussed above is $170,750 in 1997, including interest of
$13,213.
 
  Operating Leases. The Company incurred rental expense of $125,734 and
$37,465 in 1996, and 1995, respectively, in connection with its office leases.
See "Note 7--Related-Party Transactions". At December 31, 1996, future minimum
lease payments for leases having initial or remaining noncancelable lease
terms in excess of one year are presented below:

6. CONVERTIBLE PREFERRED STOCK, COMMON STOCK, AND WARRANTS.
 
  In connection with a $2.5 million private placement in December 1994 (the
"1994 Private Placement"), Zydeco issued 781,255 shares of convertible
preferred shares. During the six month period ended June 30, 1995, Zydeco
issued 218,753 common shares for nominal consideration. In connection with the
Merger, 1,875,000 shares of Common Stock were effectively issued to the
shareholders of TN Energy with entries to common stock and additional paid-in
capital totaling $7,971,525, the net assets of TN Energy on the date of the
Merger (comprised primarily of cash and marketable securities).
 
  Conversion of Preferred Stock. Shares of Convertible Preferred Stock, par
value $.001, were subject to conversion at a rate of one share of Common Stock
for each share of Convertible Preferred Stock upon either (i) the occurrence
of a successful public offering or (ii) in the event the closing price for the
Common Stock equaled or exceeded $6.50 for a period of 30 consecutive trading
days. The price of the Common Stock exceeded the minimum price for the
required period in June 1996, and, accordingly, the Company exercised its
option to convert all shares of Convertible Preferred Stock to Common Stock
effective July 15, 1996.
 
  Placement Warrants. In connection with the 1994 Private Placement, Zydeco
issued 72,268 Common Stock purchase warrants ("Placement Warrants") to the
participating placement agents, each of which entitles the holder to purchase
one share of Common Stock at an exercise price of $1.60 per share at any time
prior to their expiration on December 1, 1999. These warrants are subject to a
cashless exercise provision (i.e., the exercise price may be satisfied by
canceling a number of unexercised warrants valued by the difference between
the exercise price and the market value of the shares). The initial value of
such warrants issued in connection with the private placement was immaterial.
No Placement Warrants had been exercised prior to 1996. In 1996, Placement
Warrants were exercised for 29,592 shares of Common Stock, net of 9,575
warrant shares tendered in satisfaction of the exercise price. At December 31,
1996, there were 33,101 unexercised Placement Warrants outstanding.
 
  Redeemable Warrants. On December 21, 1993, the Company sold 1,500,000 units
("Units") in its initial public offering ("IPO"). Each Unit consists of one
share of the Company's Common Stock, $.001 par value, and two redeemable
Common Stock Purchase Warrants ("Redeemable Warrants"). Each Redeemable
Warrant entitles the holder to purchase from the Company one share of Common
Stock at an exercise price of $5.50, during the period commencing on the later
of the consummation by the Company of a Business Combination or
 
                                     F-12

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
one year from the effective date of the IPO, effectively December 20, 1995,
and ending seven years from the effective date of the IPO, effectively
December 13, 2000. The Merger constituted a business combination under the
terms of the Redeemable Warrants. The Redeemable Warrants will be redeemable
at a price of $.01 per warrant upon 30 days' notice at any time, only in the
event that the last sale price of the Common Stock is at least $10.00 per
share for 20 consecutive trading days ending on the third day prior to the
date on which notice of redemption is given.
 
  The Company also issued, in connection with the IPO, an aggregate of
$150,000 of promissory notes to certain accredited investors. These notes bore
interest at the rate of 10% per annum and were repaid on the consummation of
the Public Offering with accrued interest thereon. In addition, the investors
were issued 300,000 Redeemable Warrants valued at a nominal amount. At
December 31, 1996, no Redeemable Warrants had been exercised.
 
  Unit Purchase Options. Also on December 21, 1993, the Company sold to the
underwriters in the IPO and their designees, for nominal consideration, the
right to purchase up to 150,000 units ("Unit Purchase Options"). The Unit
Purchase Options are exercisable initially at $6.60 per Unit ("Option Exercise
Price") until December 13, 1998, when they expire. The Unit Purchase Options
contain anti-dilution provisions providing for adjustment of the Option
Exercise Price upon the occurrence of certain events, including the issuance
of shares of Common Stock or other securities convertible into or exercisable
for shares of Common Stock at a price per share less than the Option Exercise
Price or the market price of the Common Stock, or in the event of any
recapitalization, reclassification, stock dividend, stock split, stock
combination, or similar transaction. The Unit Purchase Options grant to the
holders thereof certain "piggyback" and demand registration rights for periods
of seven and five years, respectively, from the date of the IPO. The
underwriters' units issuable upon the exercise of the Unit Purchase Options
are identical to the Units discussed above, except that the warrants contained
therein expire five years from the effective date of the IPO, or December 13,
1998, and cannot be redeemed. At December 31, 1996, no Unit Purchase Options
had been exercised.
 
  Non-Redeemable Bridge Warrants. In December 1995, in connection with
arranging the Bridge Financing, the Company issued to the Bridge Lenders
warrants to purchase 225,028 shares of Common Stock ("Non-Redeemable Bridge
Warrants"), at an exercise price of $5.33 per share. The terms of the Non-
Redeemable Bridge Warrants are identical to the terms of the Redeemable
Warrants, except that they are not redeemable and are subject to a cashless
exercise provision. At December 31, 1996, no Non-Redeemable Bridge Warrants
had been exercised.
 
7. RELATED-PARTY TRANSACTIONS.
   
  In June 1996, the Company, with the approval of the Board of Directors (Mr.
Sam B. Myers, Jr. abstaining), purchased all the working interest in certain
unproved properties consisting of five non-producing offshore oil and gas
leases from entities beneficially owned or controlled by affiliates (the
"Myers Affiliates") of the Company's Chief Executive Officer, Mr. Sam B.
Myers, Jr. The Board of Directors, then composed of a majority of three
outside directors, reviewed the related-party transactions discussed above,
including the geological and geophysical studies prepared by the Company's
geologist and exploration vice president. Two of the three independent
directors are experienced chief executive officers of publicly traded
companies with oil and gas operations and negotiated the transactions,
including certain terms regarding price and the amount of retained interests.
The information reviewed and discussed by the Board included analysis of
possible reserves, typical reservoir economics, representative costs of
drilling and completion of wells and costs of production platform
construction. The Company paid $302,464 (represented by the Myers Affiliates
as its accumulated cost in the property interests) for the leases which are
located in state waters offshore Louisiana. The leases are subject to 7.5%
back-in after payout by the Myers Affiliates. The Myers Affiliates also own an
aggregate of between 4.5% and 7.5% overriding royalty interest in these
leases, which interests were owned by the Myers Affiliates prior to     
 
                                     F-13

                      ZYDECO ENERGY, INC. AND SUBSIDIARY
 
            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
this transaction with the Company. In addition, two Vice Presidents and an
employee of the Company (formerly officers of certain Myers Affiliates) own
overriding royalty interests under the leases and one such employee received
an additional 1% overriding royalty interest pursuant to an employment
contract. In addition, at the time of purchase of the property interests, the
two Vice Presidents also received an aggregate one-half percent overriding
royalty interest in the properties directly from the Myers Affiliate. In May
1996, the Company purchased certain proprietary geologic and geophysical data
and computer equipment which was being utilized by the Company from a Myers
Affiliate for $145,490.
   
  In August 1996, the Company, with the approval of the Board of Directors
(Mr. Sam B. Myers, Jr. abstaining), purchased non-producing leasehold
interests owned by a Myers Affiliate and agreed to participate in the drilling
of an exploratory well located in Timbalier Bay in state waters offshore
Louisiana. The Company paid $187,500 for a 37.5% working interest in the
drilling prospect. The Myers Affiliate owns an aggregate of between 33.1% and
37.25 % net revenue interest in the prospect leases and Mr. Myers owns an
approximate 1.6% net revenue interest under portions of the leases. The Myers
Affiliates participated in the well with a working interest of 41.2% and paid
their proportionate share of the estimated cost of drilling and completion of
the well. The Myers Affiliates can also back-in for 25% of the well after
payout. In addition, an affiliate of a director of the Company also purchased
a 5% working interest in the properties on the same basis as the terms of the
Company's participation. Two of the Company's Vice Presidents also own net
revenue interests in the prospect leases, one of which also purchased an
additional 1% working interest participation in the property at the same time
and on the same basis as the terms of the Company's participation. Drilling of
the well commenced in August 1996. In September 1996 while drilling for
hydrocarbon objectives at a depth over 10,000 feet, the drillstring
encountered caving of the wellbore due to the high angle of drillstring bend
designed to reach multiple objectives and the inability of the drilling mud
system to control the wellbore's condition. The well was abandoned as a result
of the increasing risk of losing the drilling contractor's drillstring in the
wellbore for which the interest owners were financially responsible. The
Company has undertaken to sell a portion or farmout its interest in this
prospect and at December 31, 1996, reflected $187,500 in unproved and
unevaluated properties related to the prospect. The Company charged $647,355
to exploration expense in 1996 in connection with the drilling and abandonment
of the well.     
 
  In 1996, the Company licensed software and purchased related software
maintenance services aggregating $325,768 from an unaffiliated vendor.
Subsequently, in October 1996, an officer and director of the Company became a
director of the vendor.
 
  The Company engaged the services of a law firm, including the services of a
partner in the firm who is a relative of an officer and director of the
Company. The Company incurred expenses of approximately $109,902 and $118,970
to this firm during the years ended December 31, 1996, and 1995, respectively.
 
  Zydeco entered into an exchange agreement, dated January 1, 1995, with an
entity beneficially owned by certain Myers Affiliates where certain officers
and/or directors are officers and/or directors of the Company, and agreed to
provide 3D seismic analysis services in exchange for a license to such data.
The value of this exchange was determined by the parties to be $200,000. As
this exchange agreement represents an exchange of dissimilar goods, income and
expense reflects the gross value of seismic service revenues and related data
costs associated with this transaction for 1995.
 
  Effective January 1, 1995, Zydeco assumed an obligation for office
facilities under an operating lease agreement expiring in March 1997, from a
Myers Affiliate where certain officers of the Company were, at the time, also
officers and/or directors of the Myers Affiliate. The lease agreement required
base monthly payments of $3,122. In connection with the relocation of the
Company's offices in June 1996, the Company bought out the remaining nine
month term under this lease for $24,615. Rental expense related to this lease
was $44,887 and $37,340 which is included in general and administrative
expenses for the years ended 1996, and 1995, respectively.

  Effective December 15, 1994, Zydeco assumed an obligation related to certain
computer equipment and related software under a capital financing lease
expiring October 1997, from a Myers Affiliate where certain officers of the
Company were, at the time, also officers and/or directors of the Myers
Affiliate. The leased equipment was assigned to the Company by such entity,
and the original lender has released the entity from all liability in the
event of the Company's non-performance.
 
8. STOCK OPTION PLANS.
 
  At December 31, 1996, the Company had three stock-based compensation plans,
which are described below. Each Plan provides for the granting of options
generally at not less than the per share market price on the date of grant.
The Company applies APB Opinion 25 and related Interpretations in accounting
for its plans. Accordingly, no compensation cost has been recognized for its
fixed stock option plans. Had compensation cost for the Company's three stock-
based compensation plans been determined based on the fair value at the grant
dates for awards under those plans consistent with the method of SFAS No. 123
"Accounting for Stock-Based Compensation", the Company's net loss and loss per
share would have been reduced to the pro forma amounts indicated below:

</TABLE>    
 
  For purposes of the above pro forma disclosure, the fair value of each
option grant is estimated on the date of grant using the Black-Scholes option-
pricing model with the following weighted average assumptions used for grants
in 1996 and 1995, respectively: no dividend yield for both years, expected
volatility of .52 and .10, risk-free interest rates of 5.2% for both years,
and expected lives of 10 years for all options. In connection with the above
assumptions, the estimated weighted average fair value of options granted in
1996 and 1995 is $4.07 and $.56 per share, respectively.
   
  In February 1995, Zydeco's board of directors approved the 1995 Employee
Stock Option Plan (the "Zydeco Plan") for certain employees of the Company and
any subsequently incorporated subsidiaries of the Company. The Zydeco Plan
provides for the granting of stock options to purchase up to an aggregate of
one million (pre-Merger) shares of common stock. Options to purchase 1,006,256
(post-Merger) shares of stock at a price of $1.60 per share, as adjusted
pursuant to the Merger, were granted in March 1995. Such options are non-
compensatory, vest over a four-year period and terminate no later than March
2005. Pursuant to the terms of the Merger, options granted pursuant to the
Zydeco Plan were assumed by the Company and an equivalent number of shares of
Common Stock are reserved for issuance upon exercise of the assumed Zydeco
Plan options. See "Note 3--Reverse Acquisition by Zydeco". Common Stock was
issued in the amount of 1,562 shares in connection with stock options
exercised in 1996, under the Zydeco Plan. Shares exercisable under vested
options issued under the Zydeco Plan aggregated 501,565 shares and 251,564
shares at December 31, 1996, and 1995, respectively.     
 
  On January 4, 1996 the Board of Directors approved and adopted the Zydeco
Energy, Inc. 1996 Incentive Equity Plan (the "1996 Incentive Plan"). The 1996
Incentive Plan authorizes the grant of various stock and stock-related awards
to key management and other personnel on the basis of individual and corporate
performance. The 1996 Incentive Plan provides for the granting of stock
options to purchase an aggregate of 350,000 shares of Common Stock, which are
reserved for such purpose. In 1996, options to purchase 495,000 shares were
granted to employees at exercise prices ranging between $5.22 and $6.69 per
share. Options for

100,000 shares of Common Stock granted in January 1996, expired in February
1996, upon termination of an employee. The net 45,000 option shares granted in
excess of the authorized limit of the 1996 Incentive Plan were granted subject
to the approval of shareholders at the Company's next Annual Meeting scheduled
in May 1997. At December 31, 1996, no options had been exercised or were
exercisable under the 1996 Incentive Plan. The weighted average exercise price
of stock options outstanding under the 1996 Incentive Plan at December 31,
1996, was $5.83 per share. Such options are non-compensatory, vest over a
four-year period and terminate no later than ten years after the date of grant
unless otherwise determined by the Compensation Committee.
 
  Also on January 4, 1996, the Board of Directors adopted the 1996 Non-
employee Directors Stock Option Plan (the "1996 Directors Plan") and granted
an aggregate of 45,000 shares of Common Stock to three non-employee directors.
The options vest, one third on April 1, 1997, 1998, and 1999, and have an
exercise price of $6.69 per share. The options terminate no later than ten
years after the date of grant. Both the 1996 Incentive Plan and the 1996
Directors Plan were approved by the Company's shareholders at the Annual
Meeting on July 9, 1996.
 
9. SEGMENT INFORMATION.
 
  The Company operates principally in one industry segment--oil and gas
exploration and production ("E&P"). In 1995, the Company also had operations
in one other reportable segment: 3D seismic analysis services. The assets
reported in the 3D seismic analysis services segment in 1995 were used in both
segments and are included in the oil and gas E&P segment in 1996. During 1994,
the Company had limited operations and no revenue, other than interest income.
The following table sets forth key operating information for each business
segment:

  Major Customers. Oil and gas sales to two customers of $1,030,424 and
$391,803, respectively, in 1996, and $133,589 to one customer in 1995, each
constituted more than 10% of consolidated revenue for such years. In addition,
3D seismic services revenue of $100,000 in 1995, from one customer represented
more than 10% of consolidated revenue for 1995.
 
10. COMMITMENTS AND CONTINGENCIES.
 
  In February 1996, the Company purchased an exclusive seismic option permit
from the state of Louisiana covering approximately 51,000 acres of state
waters in western Cameron Parish, Louisiana. The Company paid $783,754 for the
permit. Under the Agreement with the state of Louisiana, the Company is
obligated to deliver within 18 months a 3D seismic survey over the state
acreage included in the permit or pay a penalty equivalent to the initial
payment for the permit and/or unspecified damages. Under the option, the State
of Louisiana is required to keep the information obtained from the survey
confidential for a period of ten years. The Company can extend the time period
for delivery of the survey for a six month period for an additional payment of
$391,877. In August, 1996, the Company commenced operations for a 3D survey
project (the "West Cameron Seismic Project") which includes the area covered
by the permit and additional contiguous land acreage.
 
  In May 1996, the Company entered into a license agreement with an individual
to use a proprietary 3D seismic processing and wavefield imaging technology
("Wavefield Imaging"). The Company is authorized to use Wavefield Imaging
worldwide and exclusively in certain transition zone areas of the Gulf of
Mexico, including the area covered by the West Cameron Seismic Project. The
Company paid the first year's royalty fee of $40,000 in May 1996, and can, at
its option, renew the license annually by payment of annual royalties as
follows:

                   1997                     $40,000
                   1998                     $60,000
                   1999                     $80,000
                   2000                     $80,000
                   Thereafter              $100,000
</TABLE>
 
  In August 1996, the Company negotiated and executed a turnkey seismic
services agreement with its survey contractor Grant Geophysical, Inc.
("Grant") in an effort to control some of the risks associated with a survey
as large as the West Cameron Seismic Project. In December 1996, after Grant
informed the Company it was ceasing survey operations due to winter weather
conditions, Grant filed for protection and reorganization under Chapter 11 of
the U. S. Bankruptcy statutes and currently is attempting to restructure its
operations. On March 14, 1997, the Company and Grant executed a new Master
Geophysical Data Acquisition Agreement ("the Agreement") to commence survey
operations in mid-April 1997 under a "cost plus" services arrangement. The

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
nature of such an agreement increases both the risks and the management
efforts associated with the seismic acquisition phase of the West Cameron
Seismic Project. The current estimates of the cost to complete the survey
(assuming no reduction in the survey area) are substantially higher than the
estimates or the actual costs incurred (approximately $44,000 per square mile)
under the former turnkey contract with Grant. The Company paid a commitment
fee of $150,000 and advanced $350,000 upon execution of the Agreement.
Management currently believes that it will be able to meet its obligations
under the Permit.

  On June 20, 1997, at the request of Fortune, the Company returned $2,153,645
to Fortune representing the unexpended funds previously advanced to the
Company under the Fortune Agreement. The funds returned to Fortune were
reported as an exploration liability on the Company's balance sheet and their
return will be accounted for as a reduction of such balance, with no effect on
working capital. The Company will retain its current undivided 50% working
interest in each of the existing properties.

  On July 1, 1997, the Company acquired Wavefield Image, Inc. ("Wavefield"), a
privately held company that develops and licenses a seismic data processing
technique known as Wavefield Imaging Technology. The Company is utilizing
Wavefield Imaging Technology in its West Cameron Seismic Project pursuant to a
license negotiated in May 1996. The Company issued 100,000 shares of Common
Stock to stockholders of Wavefield, including its founder, Dr. Norman S.
Neidell, in exchange for all of the outstanding stock of Wavefield. An
additional 150,000 shares of Common Stock are expected to be issued to
Wavefield's stockholders with respect to a patent for the Wavefield Imaging
Technology, for which the Company received notice on July 3, 1997, that the
application has been allowed for issuance of a patent by the United States
Patent and Trademark Office. The historical operations of Wavefield are not

         SUPPLEMENTAL INFORMATION ON OIL AND GAS PRODUCING ACTIVITIES
 
  The following unaudited information has been provided pursuant to Statement
of Financial Accounting Standards No. 69 "Disclosures about Oil and Gas
Producing Activities". There are numerous uncertainties inherent in estimating
quantities of proved reserves and in projecting future rates of production and
timing of development expenditures, including many factors beyond the control
of the Company. Reserve engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
way. Accordingly, reserve estimates are often different from quantities of oil
and gas that are ultimately recovered. The Company's proved oil and gas
reserves were estimated by Ryder Scott Company, Petroleum Engineers.
 
PROVED DEVELOPED RESERVE QUANTITIES
 
  The Company's oil and gas producing activities have been conducted solely in
the United States. The Company had no proved undeveloped reserves at December
31, 1996, 1995, or 1994. The following table sets forth the changes in the
Company's total proved reserves (all of which are developed) for the periods
ended December 31, 1996, 1995, and 1994:

STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATING TO PROVED
OIL AND GAS RESERVE QUANTITIES
 
  Future cash inflows from the sale of production of proved reserves, net of
estimated production and development costs, as calculated by the Company's
independent reserve engineers, are discounted at 10%. The calculations are
based on year-end prices and costs and statutory tax rates that relate to
existing proved oil and gas reserves in which the Company has mineral
interests. Actual oil and gas sales prices continue to be subject to wide
fluctuations due to market changes. The standardized measure is not intended
to represent the market value of reserves and, in view of the uncertainties
involved in the reserve estimation process, including the instability of
energy markets, may be subject to material future revisions. See "Note 1--
Organization and Summary of Significant Accounting Policies".

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
  Section 145 of the Delaware General Corporation Law ("Section 145") permits
indemnification of directors, officers, agents and controlling persons of a
corporation under certain conditions and subject to certain limitations.
Article Eighth of the Company's Certificate of Incorporation and Section 8.1
of the Company's Bylaws) provide for the indemnification of directors,
officers and other authorized representatives of the Company to the maximum
extent permitted by the Delaware General Corporation Law. Section 145 empowers
a corporation to indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation or enterprise.
Depending on the character of the proceeding, a corporation may indemnify
against expenses (including attorneys' fees), judgments, fines and amounts
paid in settlement actually and reasonably incurred in connection with such
action, suit or proceeding if the person seeking indemnification acted in good
faith and in a manner he reasonably believed to be in or not opposed to the
best interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful. In
the case of an action by or in the right of the corporation, no
indemnification may be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine that despite the adjudication
of liability such person is fairly and reasonably entitled to indemnity for
such expenses which the court shall deem proper. Section 145 further provides
that to the extent a director or officer of a corporation has been successful
in defense of any action, suit or proceeding referred to above or in defense
of any claim, issue or matter therein, he shall be indemnified against
expenses (including attorneys' fees) actually and reasonably incurred by him
in connection therewith.
 
  Section 8.6 of the Company's Bylaws permits it to purchase and maintain
insurance on behalf of any such person who is or was a director, officer,
employee or agent of the Company or is or was serving at the request of the
Company, as a director, officer, employee or agent of another corporation or
enterprise against any liability asserted against him and incurred by him in
such capacity, or arising out of his status as such, whether or not the
Company would have the power to indemnify him against such liability under the
foregoing provisions of the Bylaws.

ITEM 17. UNDERTAKINGS
 
  (1) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, the
registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred by paid by a director officer or controlling
person in the successful defense of any action, suit or proceeding) is
asserted by such director, officer or controlling person in connection with
the securities being registered, the registrant will, unless in the opinion of
its counsel the matter has been settled by controlling precedent, submit to a
court of appropriate jurisdiction the question whether such indemnification by
its against public policy as expressed in the Act and will be governed by the
final adjudication of such issue.
 
  (2) The undersigned registrant hereby undertakes that:
 
    (a) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (b) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.
