                Subject to Completion Dated May 30, 2000

                           CANAAN ENERGY CORPORATION


                        PARTNERSHIP ROLLUP TRANSACTION

          Canaan Energy Corporation, an Oklahoma based oil and gas company
previously known as Coral Reserves Group, Ltd., is offering shares of common
stock in connection with a plan of combination.  Under the plan:

          .    Canaan will acquire all of the limited partners' interests in
               eight private oil and gas limited partnerships previously
               sponsored by Coral Reserves, Inc. and Coral Reserves Energy
               Corp., affiliates of Canaan.

          .    Canaan will acquire 100% of the stock of Coral Reserves, Inc. and
               Coral Reserves Energy Corp.

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock.


          The owners of each of the entities involved in the transactions will
receive shares of Canaan common stock in proportion to the exchange value of
such entity relative to the total exchange value of all entities. Limited
partners will have a right to receive cash as described in this document. A
total of 5,000,000 shares of Canaan common stock will be issued and be
outstanding after the combination transactions, less the number of shares
otherwise issuable to limited partners who elect to receive cash.


          The plan of combination requires the approval of limited partners and
the plan requires that all partnerships adopt the plan. A combined special
meeting of the partnerships to vote on the plan is scheduled for__________,
2000.

          Prior to this transaction there has been no public market for Canaan
common stock. Canaan has applied for shares to be quoted in the NASD National
Market System under the proposed symbol "KNAN".

          Neither the Securities and Exchange Commission nor any state
securities commission has approved or disapproved of these securities or
determined if this document or the accompanying prospectus supplement is
truthful or complete. Any representation to the contrary is a criminal offense.



          The combination transactions involve various risks. Please See
"Summary - Risk Factors" beginning on Page 20 and "Risk Factors and Material
Considerations" on Page 30. These risks include among others:


 .   Fundamental change in nature of investment.


 .   Elimination of cash distributions.


 .   No prior market for Canaan common stock.

 .   Conflicts of interest in establishing terms of the transaction.

 .   Uncertainties in valuation process.

 .   No adjustment for changes in commodity prices.

 .   Continuation or liquidation of partnerships could be more beneficial to the
    limited partners.


 .   No independent representative of limited partners or fairness opinion.


    The Information in this document is not complete and may be changed. We may
    not sell these securities until the registration statement filed with the
    Securities and Exchange Commission is effective. This prospectus is not an
    offer to sell these securities and it is not soliciting an offer to buy
    these securities in any state where the offer or sale is not permitted.

                             QUESTIONS AND ANSWERS


Q:   What is being proposed?

A:   Canaan is proposing a series of combination transactions to combine eight
     private limited partnerships previously sponsored by its affiliates and
     Indian Oil Company and Canaan Securities, Inc. into a new publicly traded
     oil and gas company.



Q:   What will I receive as a result of the combination transactions?

A:   Limited partners will receive shares of Canaan common stock based on the
     relative value of their ownership interest in a partnership compared to the
     total value of all entities involved in the transaction. The number of
     shares limited partners will receive in each partnership is estimated on
     page 16. The method of determining relative value is described on page 62.


Q:   What happens to my partnership cash distributions?

A:   The partnerships currently pay limited partners regular cash distributions.
     You will continue to receive cash distributions from the partnerships until
     closing of the combination transactions. Thereafter, you will receive no
     further cash distributions from the partnerships or dividends as Canaan
     does not anticipate paying dividends on its common stock.

Q:   What if I do not want Canaan common stock?

A:   A limited partner may elect to receive cash in lieu of Canaan common stock
     in an amount equal to the appraisal value of his interest based on an
     appraisal of the partnership assets by an independent appraiser.  There is
     a limit of $15 million on the amount of cash payable to electing limited
     partners.


Q:   What are the tax consequences of the combination transactions?

A:   The combination transaction will be treated as a transfer of your interest
     in a partnership to Canaan and be tax free to you, unless you elect to
     receive cash.  After the combination transactions, you will be a
     shareholder rather than a limited partner so you will no longer receive the
     pass-through tax treatment accorded to partners and you will no longer
     receive a Schedule K-1.  You should consult your tax advisor concerning the
     Federal and other tax consequences of the proposed combination
     transactions.

Q:   What do I need to do now?

A:   After carefully considering the enclosed information, please indicate how
     you want to vote and sign and return your proxy and cash election form and
     letter of transmittal in the enclosed envelope as soon as possible.  Your
     interest will then be voted at the special meeting in accordance with your
     instructions.


                                      -1-
<PAGE>

Q:   What happens if I don't vote my interest?

A:   The failure to vote at the special meeting will have the same effect as
     voting against the combination transactions.

Q:   When do you expect the combination transactions to be completed?

A:   We expect the combination transactions to be completed within one or two
     business days after receiving approvals of all partnerships at the special
     meeting.

Q:   When will shares of Canaan begin trading?

A:   We anticipate that Canaan shares will begin trading on the NASDAQ National
     Market System on the day after the combination transactions are completed.

Q:   How do I sell my shares of Canaan?

A:   Once you receive your new certificate for shares of Canaan common stock you
     can sell your shares of Canaan through any brokerage firm.  It is
     anticipated that certificates for Canaan common stock will be issued
     promptly after completion of the combination transactions if you have
     previously submitted a properly completed and executed letter of
     transmittal.

Q:   What do the General Partners of the partnerships recommend?

A:   The General Partners and Canaan recommend that limited partners vote for
     approval of the combination transactions.

Q:   Who can help answer additional questions that I may have?


A:   Canaan Energy Corporation - (405) 232-3222.  However, Canaan has conflicts
     of interests in connection with the transaction as described elsewhere in
     this document.

The Parties

Canaan Energy Corporation
119 N. Robinson, Suite 600
Oklahoma City, OK 73102

          Canaan, formerly known as Coral Reserves Group, Ltd., is an
independent oil and gas company headquartered in Oklahoma City, Oklahoma.
Canaan was formed in March, 1987, as an Oklahoma corporation, by Leo E. Woodard
and John K. Penton.  Mr. Woodard continues to serve the company as chief
executive officer and Mr. Penton serves as president.

          Canaan has been continuously engaged in the acquisition, production,
development and operation of oil and natural gas properties.  As of December 31,
1999, Canaan operated 110 wells in which it or the partnerships own an interest.
Operations are located entirely within the state of Oklahoma and are
concentrated in Kingfisher County in north central Oklahoma and Garvin and
McClain counties in south central Oklahoma.  As of December 31, 1999, the
estimated present value of Canaan's proved oil and gas reserves was less than
$500,000.

          Since 1990, when Coral Reserves, Inc. and Coral Reserves Energy Corp.
began sponsoring partnerships, Canaan has provided management services to them
as the General Partners of the partnerships.

          As a result of the combination transactions, Canaan will acquire all
of the other parties to the combination transactions and the equity owners of
the other parties to the combination transactions will become shareholders of
Canaan.  Canaan will continue the combined businesses of the entities involved
after the completion of the combination transactions.

          Canaan is currently 100% owned by its management, Leo E. Woodard,
47.5%, John K. Penton, 47.5%,  and Michael S. Mewbourn, 5%.

activities.

          Coral Reserves Energy Corp., which we refer to as Coral Corp., serves

          We occasionally refer to Coral, Inc. and Coral Corp. individually as
"General Partner" and collectively as "General Partners".

          Coral Reserves, Inc. and Coral Reserves Energy Corp. are affiliated
with Canaan by common management and ownership.  Each of these companies is
owned by management of Canaan in the same ownership percentages that they own of
Canaan which are Leo E. Woodard, 47.5%, John K. Penton, 47.5%, and Michael S.

Indian Oil Company
9400 North Broadway, Suite 800
Oklahoma City, OK 73114

          Indian Oil Company is a privately-held Oklahoma corporation which is
engaged in oil and gas exploration, development and production, primarily in
Oklahoma.  Indian is not affiliated with Canaan or the General Partners.  On
February 15, 1999, Indian,  Canaan and the General Partners entered into an
agreement for Canaan to acquire Indian as a part of the combination transactions
and since that date Canaan has been responsible for the day to day management of
Indian subject to control by the Indian board of directors.

          Indian is owned by five stockholders who are not currently affiliated
with Canaan, including Anthony Lasuzzo, a proposed executive officer of Canaan.

Canaan Securities, Inc.

New Canaan, CT 06840

          Canaan Securities, Inc. is not affiliated with Canaan and the General
Partners and is a registered broker/dealer with the SEC and the National
Association of Securities Dealers. Canaan Securities served as a placement agent
in connection with the private placement of the limited partnership interests in
the partnerships.  Canaan Securities also engaged other unaffiliated brokers to
assist in the placement, which are referred to as "Placing Brokers". Canaan
Securities and the Placing Brokers receive fees for these services based on the
partnerships' ongoing cash distributions from oil and gas properties.  In
addition, Canaan Securities provides ongoing

                                      -4-

continues to receive fees based on the partnerships' revenues from oil and gas
properties. Canaan Securities does not engage in any other business activities.

          Canaan Securities is 100% owned by Thomas H. Henson, a proposed
executive officer and director of Canaan.

The Partnerships
119 N. Robinson, Suite 600
Oklahoma City, OK 73102

          The partnerships consist of Oklahoma limited partnerships previously
sponsored by the General Partners for purposes of acquiring producing oil and
gas properties primarily in Oklahoma and conducting limited additional
development activity relating to the acquired properties.  In each of the
partnerships, Leo Woodard and John Penton, officers and shareholders of Canaan,
serve as "Additional General Partners".  Each of the partnerships raised capital
in private offerings from limited partners, primarily individuals and
substantially all of whom are considered "accredited investors" under the
federal securities laws.  There is no market for the limited partnership
interests and Canaan and the General Partners are not aware of any purchases or
sales of interests within the last five years except for isolated transactions
not involving brokers or other market participants.  The following table sets
forth information about the partnerships:

          The cost sharing in each partnership provides for limited partners to
bear all of the costs of acquisition and development of the partnership's oil
and gas properties until capital contributions of limited partners were fully
expended.  Thereafter, capital expenditures are shared based on revenue sharing
percentages.  As provided by the terms of each partnership, the General Partner
and Additional General Partners did not make any capital contributions for their
interests in the partnership.  The sharing of partnership net revenues and cash
distributions for all partnerships except 1993-I and 1996-I vary depending on
whether "payout" has occurred. Payout is calculated on an individual limited
partner basis and is the point when cash distributions to such partner equal the
amount of original investment.  As of December 31, 1999, the 1990 and 1991
partnerships have achieved payout for all limited partners and the 1992
partnership has achieved payout as to some of the limited partners.  The other
partnerships have not reached payout.  The following table sets forth
information about the ongoing net revenue and cash distribution sharing in each
of the partnerships:

 The Combination Transactions

          The combination transactions consist of:

          .    The acquisition of all of the limited partners' interests in each
               of the partnerships by Canaan by a merger between each
               partnership and separate acquisition corporations organized by
               Canaan for purposes of the transactions;

          .    The acquisition of 100% of the stock of the General Partners of
               the partnerships by Canaan;

          .    The acquisition of 100% of the stock of Indian by Canaan.

          .    The acquisition of 100% of the stock of Canaan Securities by
               Canaan; and

          .    An increase in Canaan's outstanding common stock held by its
               current shareholders to result in the appropriate number of
               shares outstanding based on Canaan's relative share of the total
               Exchange Value.

          A total of 5,000,000 shares of Canaan common stock will be issued and
be outstanding after the combination transactions, less the number of shares
otherwise issuable to limited partners who elect to receive cash.  The owners of
each of the entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of such entity relative to the total Exchange Value of all
entities.  The Exchange Value has been determined by Canaan and is based on a
valuation of each entity's oil and gas reserves and other assets and
liabilities.  Any limited partner in any partnership may elect to receive cash
in lieu of Canaan common stock equal to the appraised value of his interest in a
partnership.


          A combined special meeting of the partnerships will be held to
consider and vote upon the proposal to adopt the plan of combination on
__________, 2000 at _____ a.m. at _________________, Oklahoma City, Oklahoma.
Proxies are being solicited by Canaan and the General Partners of the
partnerships. Adoption of the plan of combination by a partnership requires the
consent of the General Partners of the partnership and a majority-in-interest of
limited partners and the plan requires that all partnerships adopt the plan.
Owners of Canaan, the General Partners, and Canaan Securities have already
unanimously approved the plan of combination. The shareholders of Indian owning
a majority of Indian common stock must also vote in favor of the plan of
combination.

Method of Determining Combination Exchange Values

General

          The Exchange Values for each of the entities was determined based on
methods determined by Canaan.  The first component of the Exchange Value is the
oil and gas reserve values for each entity's oil and gas properties as estimated
by Netherland, Sewell & Associates, Inc. an independent petroleum engineering
and consulting firm.  Netherland Sewell estimated the reserves, future net
revenues therefrom, and the present value of such future net revenues for each
entity involved in the transaction as of September 30, 1999 using the following
assumptions:

          .    Gas prices were established for each well separately based on a
               ----------
               12 month average of gas prices for the 12 months ending March 31,
               2000. This average was constructed using the average of composite
               spot wellhead prices as published by Natural Gas Week for the 8
               months ending November 30, 1999 and the forward market prices for
               the 4 months ending March 31, 2000 based on futures prices quoted
               on the New York Mercantile Exchange ("NYMEX") as of October 29,
               1999 adjusted for the historical differential between NYMEX and
               Natural Gas Week composite spot wellhead prices. The prices for
               all wells averaged $2.52 per MMbtu before adjustment by well for
               transportation fees, BTU content and regional price differentials
               and were held constant for the life of the properties. After
               adjustments by well for transportation fees, BTU content and
               regional price differentials, the weighted average gas price for
               all wells in the report was $2.43/Mcf. The actual weighted
               average gas price for all wells for all entities as of September
               30, 1999 was $2.49/Mcf.

          .    Oil prices were established for each well separately based on
               ----------
               an 8 year average of West Texas Intermediate crude oil posted
               prices for the 8 year period beginning in 1992 and ending on
               December 31, 1999. This average was constructed using average
               posted prices for West Texas Intermediate crude oil for 1992
               through October 1999 and the forward market prices for November
               and December of 1999 as quoted on NYMEX as of October 29, 1999
               adjusted for the differential between such forward market prices
               and West Texas Intermediate posted prices. The prices for all
               wells averaged $18.10 per barrel before adjustment by well for
               gravity, transportation fees and regional price differentials and
               were held constant for the life of the properties. After
               adjustments by well for gravity, transportation fees and regional
               price differentials, the weighted average oil price for all wells
               in the report was $19.68/Bbl. The actual weighted average oil
               price for all wells for all entities as of September 30, 1999 was
               $22.81/Bbl.

          .    Operating costs and production taxes were based on costs and tax
               ------------------------------------
               rates in effect as of September 30, 1999 and were not escalated.

          .    A discount rate of 10% was used to discount future net revenues
               ---------------
               to present value at September 30, 1999.

          We refer to the evaluation date of September 30, 1999 as the
"Effective Date" and we refer to the present value of the estimated future net
revenues from oil and gas reserves as of the Effective Date as the "Reserve
Value" for each entity involved in the combination transaction. A summary of the
reserve reports prepared by Netherland, Sewell & Associates showing the Reserve
Value for each entity is included in Appendix A.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term proved
reserves is defined by the Society of Petroleum Engineers.  However, because the
reserves are estimated using prices different from those required by the
Securities and Exchange Commission, we use the term "Exchange" instead of
"proved" to describe the reserve estimates for the Exchange Value.  Properties
with developed reserves have less risk than properties with undeveloped
reserves.  However, there was no risk factor assigned to the type of reserves
for purposes of determining the Reserve Values.  No attempt was made to assign
value to oil and gas reserves categorized as probable or possible because the
General Partners and Canaan believe such reserves are too speculative to value.
Further, no value has been assigned for purposes of the combination transaction
to any undeveloped acreage or prospects owned by any entity which does not
contain Exchange Reserves.


          In addition to the Reserve Value, the Exchange Value will take into
consideration other assets and liabilities for each entity and additional
adjustments will be made to the value of Canaan, Indian and the 1996 and 1996-I
Partnerships for purposes of determining the Exchange Value as described below.


          The "Exchange Value" for each entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the Effective Date.

          .    Plus or minus working capital at the Effective Date.

          .    Minus interest paid or accrued on bank debt from the Effective
               Date to the closing date.

                                      -9-

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.


          .    For Canaan, an upward adjustment for the value of its "operating
               rights" as described below.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for a production payment
               obligation of Indian described below.

Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners, the General Partner and the
Additional General Partners in each partnership and Canaan Securities and the
Placing Brokers, the Exchange Value will generally be allocated among them in
the ratio in which net revenues and cash distributions are shared. In each of
the partnerships except 1993-I and 1996-I, the General Partners' share of the
net revenues and cash distributions increases when "payout" occurs as to each
individual limited partner. Accordingly, in each of those partnerships in which
payout has not already occurred as to all limited partners as of the Effective
Date, the Reserve Value was allocated first among the parties in their
respective before payout sharing ratios until payout occurred and any remaining
Reserve Value and other components of Exchange Value were allocated in
after-payout sharing ratios.


          For the limited partners, the Additional General Partners, Canaan
Securities and the Placing Brokers, an adjustment to their Exchange Values will
be made for cash distributions from production subsequent to the Effective Date
and before the closing date.

          If the allocation of Exchange Value within a partnership, plus
historical cash distributions, is not at least 115% of capital contributions of
the limited partners as a group, the Exchange Value shall be first allocated to
limited partners until this amount is achieved and the balance of the Exchange
Value will be allocated based on revenue sharing percentages.  Canaan and the
General Partners believe that the 1996 partnership will be the only partnership
in which this priority allocation of Exchange Value may be necessary.

Canaan Exchange Value

          The Exchange Value for Canaan will be determined based on its Reserve
Value, bank debt and working capital in the same manner as other entities as
described above.

          Canaan's Exchange Value within the Coral Group will be further
adjusted to take into account its operating rights. As of December 31, 1999,
Canaan served as operator of 110 wells in which the partnerships owned
interests. As such, Canaan receives monthly operating fees which represent a
source of additional income to Canaan. For purposes of calculation of Canaan's
Exchange Value within the Coral Group, the future cash flows attributable to
these operating fees, based on existing reimbursement rights without escalation,
has been determined and the present value thereof as of the Effective Date will
be an additional component of its Exchange Value. The amount of this adjustment
is $5.0 million.

          For purposes of determining relative Exchange Values between Indian
and the Coral Group as a whole, the operating rights value allocated to Canaan
is disregarded because the combination of the Coral Group results in the
elimination of a significant portion of Canaan's operating fees. After the
combination transaction, Canaan will no longer receive operating fees from the
partnerships but will continue to receive fees from other unrelated owners.
Further, Canaan and Indian have agreed that neither of them will be allocated
value for operating rights for purposes of determining the Exchange Value. This
agreement is advantageous to the Coral Group because Indian's operating fees are
higher than Canaan's.

Indian Exchange Value

          The Exchange Value for Indian will be determined using the Reserve
Value, bank debt and working capital in the same manner as described above.

          In connection with the negotiation of the acquisition agreement
between Indian and Canaan, Indian agreed that its Exchange Value would be
reduced by its production payment obligation to the 1996 and 1996-I
partnerships, in consideration of such partnerships advancing to Indian a total
of $6 million in exchange for a "Contingent Production Payment" from Indian to
the partnerships payable at the rate of $56,250 per month until paid in full.
The Contingent Production Payment is $9 million if the combination transactions
are consummated and $6 million if they are not. Accordingly, Indian's Exchange
Value will be adjusted downward by the remaining amount of the Contingent
Production Payment obligation as of the Effective Date, $5,602,250, plus the
additional $3 million as a result of the combination transactions, and the
Exchange Values for the 1996 and 1996-I partnerships will be adjusted upward by
the same amount. As between the 1996 and 1996-I partnerships, the Contingent
Production Payment adjustment will be shared in the same percentages as their
original advances to Indian of 53% for 1996 and 47% for 1996-I.

Summary of Estimated Exchange Values

          The following tables summarize the estimated Exchange Values allocated
to the various parties.  All of these tables assume closing of the combination
transactions on July 31, 2000, and use actual cash distributions and interest
expense through March 31, 2000, and estimated revenues and expenses from the
Netherland Sewell reserve reports for purposes of calculating estimated cash
distributions thereafter.  Variances in actual cash distributions and interest
expense or a change in the closing date will result in a change in the Exchange
Value for any entity affected.

          The "Estimated Exchange Value" as of the closing date for the
partnerships and Canaan set forth in the table is approximately 96.3% of the sum
of their respective components of Exchange Value because the operating rights
adjustment to Canaan's Exchange Value within the Coral Group is excluded for
purposes of computing the relative Exchange Value between the Coral Group and
Indian.

          "Closing Date Estimated Exchange Value" and percentages reflect
effects of elimination of the Canaan operating rights adjustment for purposes of
the relative Exchange Values between the Coral Group and Indian. "Total Coral
Group with Operating Fees" calculates Reserve Value including operating fees
paid by partnerships to Canaan. "Total Coral Group without Operating Fees"
excludes operating fees paid to Canaan so that it is calculated on a consistent
basis with the Exchange Value calculation for Indian.

Determination of Appraised Value

          A limited partner may elect to receive cash equal to the "Appraised
Value" of his interest in a partnership. The Appraised Value was determined
based on an appraisal by Madison Energy Advisors of each partnership's oil and
gas properties as of the Effective Date. The oil and gas properties of each
partnership were valued as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice,
taking into consideration costs of sale. An adjustment was made to reduce the
appraised value of the properties for oil and gas net revenues between the
Effective Date and the closing date, so the property value is established on the
same date as the Exchange Value.

          Canaan and the General Partners then computed the estimated value of
each limited partner's interest in a partnership based on the assumption that
the partnership's oil and gas properties were sold for the resulting value and
the gain on sale was allocated to the partners in accordance with the provisions
of the applicable partnership agreement and that each partnership was
liquidated, with the proceeds of liquidation, including estimated working
capital at the closing date, and after payment of any partnership debt as of the
closing date being distributed as required by the partnership agreement. A
further adjustment will be made for any gas imbalances which are not expected to
be material. The resulting amount is referred to as the "Appraised Value".

          The economic terms of each of the partnerships generally provided for
the limited partners to provide all of the capital of the partnership and to
bear a greater percentage of the share of costs associated with each
partnership's initial acquisition and development of properties. As a result,
the limited partners in each partnership have capital account balances which are
higher, on a relative capital account basis, than their interest in revenues of
the partnership. The partnership agreement for each partnership requires that
the capital accounts be recognized or "balanced" in connection with any
liquidation of a partnership. These balancing provisions result in the limited
partners receiving a priority allocation of the liquidation proceeds as a result
of their relatively higher capital account balances. The effect of this priority
allocation is that the limited partners receive a greater share of liquidation
proceeds than what limited partners would have received from the production of
the oil and gas properties owned by each partnership had the properties been
produced to depletion. Any liquidation of a partnership would therefore result
in a relative higher proportion of value being allocated to the limited partners
than is being done in connection with the combination transactions in which the
allocation between the limited partners and the general partners is being done
based on revenue sharing percentages. However, Canaan and the General Partners
believe that the discounted prices expected to be realized in a sale of
properties in a liquidation offsets any potential incremental liquidation value
allocated to limited partners.

          For purposes of determining the appraised value of partnership oil and
gas properties, Madison calculated the estimated present value of future net
revenues from production of oil and gas reserves, but used price assumptions
different from those being used to calculate Exchange Value, applied certain
risk factors to nonproducing or undeveloped reserves and used a discount rate of
20%.

          Madison Energy Advisors provides oil and gas reserve acquisition,
divestment and valuation advisory services to the upstream oil and gas industry,
including fair market value assessments of oil and gas properties. Madison
Energy has offices in Houston, Texas and Denver, Colorado, and has a staff of
professionals with significant experience in advising both buyers and sellers of
oil and gas properties. Madison Energy was selected to perform this appraisal
because it is one of the recognized valuation experts in the industry.

          For additional information concerning the methodology used in
calculating the Appraised Value, see "Method of Determining Combination Exchange
Values - Appraised Values" beginning on page 8.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to equal such amount. Canaan and the General Partners believe
that the 1996 and 1996-I partnerships will be the only partnerships in which the
Appraised Value plus historical cash distributions may not meet the 110% of
original investment amount.

          The Appraised Value for each partnership ranges from 56% to 93% of the
Exchange Values. The following table sets forth for each partnership the
historical and estimated cash distributions, the estimated Appraised Value, and
cash distributions and Appraised Value as a percent of original investment for
the limited partners as a group and for each limited partner per $1,000 of
investment. All of these tables assume closing of the combination transactions
on July 31, 2000, and use actual cash distributions and interest expense through
March 31, 2000, and estimated revenues and expenses from the Netherland Sewell
reserve reports for purposes of calculating estimated cash distributions
thereafter. Variances in actual cash distributions and interest expense or a
change in the closing date will result in a change in the Appraised Value for
any entity affected.

Risk Factors

          There are numerous risks associated with the combination transactions
which are summarized below.  For a more complete description of these risk
factors, please see "Risk Factors".

Risks Related to the Combination Transactions

 .    Limited partners will own stock in a corporation with perpetual existence
     rather than a partnership interest in a limited partnership with a limited
     life resulting in material changes in the nature of their investment.

 .    Limited partners have received cash distributions from the partnerships
     but will receive no cash distributions or dividends in the foreseeable
     future from Canaan.

                                      -20-
<PAGE>

 .    There has been no prior market for our common stock and there is no
     assurance that a market will develop.  There is no assurance that the value
     of the common stock received by a limited partner will be equal to the
     Exchange Value.  The Exchange Values are being used solely to determine the
     relative ownership of Canaan by each entity involved and do not necessarily
     represent the fair value of Canaan or its net assets.

 .    The consideration to be received by the limited partners and the General
     Partners and Canaan and the other terms of the combination transactions
     were determined by Canaan and the General Partners, which have inherent
     conflicts of interest, and may not reflect the value of the net assets of
     the respective partnership if sold to an unaffiliated third party in an
     arms length negotiation.

 .    The Exchange Values were based primarily on estimates of reserves and
     future net cash flows which has inherent uncertainties.  Exchange Values do
     not represent fair market value.

 .    The price assumptions used to calculate the Reserve Value will not be
     modified for changes in prices which could alter the relative values of the
     entities involved or the relative share of the limited partners and General
     Partners in partnerships which have not achieved payout.

 .    The alternative of continuing the partnerships or liquidating their assets
     could potentially be more beneficial to limited partners than the
     combination transactions.

 .    No independent representative was engaged to represent the limited
     partners in negotiating the terms of the combination transactions which may
     be inferior to those that could have been negotiated by an independent
     representative.  No fairness opinion has been obtained regarding the
     fairness of the combination transactions to limited partners.


 .    The cash being offered to limited partners who elect to receive cash is
     intended to approximate the fair market value of their interests in a
     partnership based on a liquidation of the partnerships, but there is no
     assurance such value is in fact fair market value.

 .    The combination transactions will reduce and dilute a limited partner's
     voting rights.

 .    The combination transactions will result in a limited partner being
     exposed to risks of a larger enterprise without restrictions on leverage.

 .    For the 1996 and 1996-I partnerships, failure to approve the combination
     transactions may result in a material adverse effect on returns to limited
     partners due to a $3 million downward adjustment in the Indian Contingent
     Production Payment.
                                      -21-
<PAGE>

 .    We have not requested a ruling from the IRS on the tax consequences of the
     combination transactions and the IRS may disagree with the opinion of our
     counsel on the tax consequences.

 .    If the combination transactions are not approved, limited partners in each
     partnership will bear a portion of the transaction expenses.

Risks Related to Canaan

 .    Our future performance depends upon our ability to find or acquire
     additional oil and gas reserves that are economically recoverable.

 .    We are subject to anti-takeover provisions in our charter that could delay
     or prevent an acquisition of our company, even if such an acquisition would
     be beneficial to our shareholders.

 .    If we are unable to retain and hire senior management and key employees,
     it will have a material impact on us.

 .    Investors will be relying on our board and management judgment regarding
     the future direction and activities of the Company

 .    We will need additional financing to grow and our ability to raise further
     financing is uncertain.

Risks Related to the Oil and Gas Industry

 .    A substantial decrease in oil and gas prices would have a material impact
     on us.

 .    Estimating our reserves and future net cash flows is difficult to do with
     any certainty.

 .    We may incur writedowns of the net book value of our oil and gas
     properties which would adversely affect our shareholders' equity and
     earnings.

 .    Operational risks in our business are numerous and could materially impact
     us.

 .    Governmental and environmental regulations could adversely affect our
     business.

 .    Competition in the oil and gas industry is strong and can harm our
     business.

Background and Reasons for the Combination Transactions

          The partnerships were formed between 1990 and 1996.  As contemplated
when the partnerships were organized, the oil and gas production from the
producing properties owned by the older partnerships has steadily declined over
time.  These reductions are due to the natural decline occurring in connection
with the depletion of oil and gas properties.  These production declines have
contributed to a reduction in cash distributions, particularly in the earlier
partnerships.  Similar production declines can be expected from the recently
formed 1996 and 1996-I partnerships in the future.  Please see "Information
Concerning the Partnerships - Selected Historical Financial and Operating Data
for Individual Partnerships" on page 121 for cash distribution information.

          Each partnership has a specified term of existence of 20 years and can
be terminated earlier upon recommendation of the General Partner with approval
of the majority-in-interest of limited partners.  At the time the partnerships
were organized, there were no specific plans to terminate any partnership on the
occurrence of any specific events.

          In 1997, Canaan and the General Partners began to consider the
possibility of combining the partnerships into a publicly held oil and gas
company in order to achieve the benefits of a corporate entity with a larger
asset base and greater growth potential than available to any individual
partnership.  Actions to implement the plan were not taken at that time pending
the closing of the offering of partnership interests for the 1996 and 1996-I
partnerships and the investment of the capital contributions in oil and gas
properties.  In addition, Canaan entered into an agreement in February 1999 to
include Indian in the combination transaction so the new company would have a
larger size.

          Canaan and the General Partners recommend that the limited partners in
each of the partnerships vote in favor of the combination transactions.  In
considering the combination transactions, Canaan and the General Partners took
into account various advantages and disadvantages of the combination
transactions to each of the partnerships and its respective limited partners.
The advantages they considered included:

          .    Canaan believes that shares of publicly-held oil and gas
               companies generally trade at values greater than their cash
               liquidation values affording limited partners potentially greater
               value than represented by the cash value of the partnership's oil
               and gas properties, either in immediate liquidation or in
               continuing the partnership. Canaan believes publicly-held oil and
               gas companies generally trade at premiums to their potential cash
               liquidation values due to values attributable to going concern
               and potential growth and due to the fact that public company
               stock valuations do not reflect discounts for nonproducing
               reserves typically applied in cash transactions.

          .    The partnerships may not have the cash nor the ability to borrow
               funds necessary to develop their non-producing reserves. This may
               result in reduction or temporary suspension of cash distributions
               in order to

                                      -23-
<PAGE>

               participate in proposals to place these non-producing reserves on
               production, or the partnerships may be forced to forego
               participation in these proposals.

          .    The continuation of the partnerships will likely result in
               declining cash distributions to limited partners as a result of
               the natural depletion of each of the partnership's oil and gas
               properties and the requirement that partnerships other than the
               1995 partnership repay borrowings with cash flow otherwise
               distributable to partners.

          .    The combination transactions permit the limited partners to
               participate in an investment in a larger company with a more
               diversified property base and a potential for growth and
               appreciation in the future. Each partnership owns interests in 52
               to 163 gross (3.5 to 27.3 net) wells whereas, on a pro forma
               basis as of December 31, 1999, Canaan will have interests in 965
               gross (192 net) wells.

          .    For limited partners whose investment is based on the potential
               for increases in oil or gas prices, ownership of stock in a
               publicly traded oil and gas company continues to afford an
               opportunity to benefit indirectly from these price increases.

          .    The structure of the transaction gives limited partners the
               opportunity to exchange their interest in the partnerships for
               common stock without immediate tax consequences or to receive
               cash equal to Appraised Value in a taxable transaction if they do
               not wish to receive Canaan common stock.

          .    The ownership of common stock in a publicly traded company will
               afford the limited partners the opportunity to liquidate their
               investment should they desire to do so.

          .    The organization of a publicly held oil and gas company will
               potentially afford access to capital and other resources that
               will provide Canaan opportunities for future growth that are not
               available in the partnerships or the other entities.

          .    The inclusion of Indian in the combination transactions adds
               reserves in the same areas as reserves owned by the Coral Group
               and further diversifies Canaan's reserve base and property
               ownership. Indian and the Coral Group are being valued in a
               consistent manner for purposes of the combination transactions.

          .    For the 1996 and 1996-I partnerships, the terms of the Indian
               Contingent Production Payment obligation to them effectively
               provide an enhanced return compared to the return such
               partnerships could realistically achieve if the combination
               transactions are not consummated.

                                      -24-
<PAGE>

          Canaan and the General Partners also considered disadvantages of the
combination transactions that included:

          .    Limited partners will own stock in a corporation which is a
               different investment objective from investing in a partnership
               designed to generate recurring cash distributions. However, the
               cash election is intended to provide limited partners the option
               to receive cash if they prefer.

          .    Limited partners will no longer receive cash distributions.
               However, most limited partners are high income or high net worth
               individuals classified as "accredited investors" under the SEC
               rules and are likely to be less dependent on partnership cash
               distributions than individuals with lower incomes or net worths.

          .    Canaan will engage in the acquisition and exploitation of new oil
               and gas properties which will expose limited partners to all of
               the attendant risks associated with such activities. The
               partnerships generally do not conduct significant drilling
               activities, but own producing properties. The activities of
               Canaan may, therefore, involve greater risks than the activities
               of the partnerships, but also offer the potential for additional
               benefits if the acquisition and exploitation activities are
               successful.

          .    Increases in prices for oil and gas may have a more direct effect
               on limited partners in the partnerships due to the immediate
               effect on potential cash distribution. However, Canaan and the
               General Partners believe that an increase in oil and gas prices
               will also have an indirect beneficial effect on the market price
               for Canaan common stock.

          .    Limited partners will become subject to the volatility of the
               market value of Canaan common stock. Market factors that may
               affect the common stock price will include factors other than
               those that affect the value of a limited partner's interest in a
               partnership, such as general market conditions.

Fairness of the Combination Transactions

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value, and are fair to the
partnerships as a whole.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions receiving Canaan common stock
is the determination of the Exchange Values.  As noted elsewhere, the Exchange
Values are based primarily on the Reserve Value based on Netherland Sewell's
independent valuations.

                                      -25-
<PAGE>

          By using Reserve Values calculated in a consistent manner by a single
engineer based on the same price, cost and discount assumptions, Canaan and the
General Partners believe that the relative value of each of the entities has
been fairly determined for purposes of determining its relative ownership of
Canaan after the combination transactions.  Canaan and the General Partners also
considered various other factors in evaluating the fairness of the combination
transactions as described under "Recommendation of the General Partners and
Fairness of the Combination Transaction" beginning on page 74.

          The cash amount being offered to limited partners electing to receive
cash is based on an appraisal of the value of each partnership's oil and gas
properties by an independent appraiser and, accordingly, Canaan and the General
Partners believe such cash election amount is fair for limited partners electing
to receive cash.

 Alternatives to the Combination Transactions

          Canaan and the General Partners have given consideration to the
alternatives of continued operation of the partnerships for a longer period or
the possibility of selling the partnership assets and liquidation of the
partnerships prior to proposing the combination transactions to limited partners
for their approval.


          Continuation of the partnerships, while avoiding the risks associated
with the combination transactions and the discontinuance of cash distributions,
would result in declining operating results and distribution rates for each of
the partnerships due to the depletion of reserves, ongoing general and
administrative expense and debt service requirements for all partnerships.  A
sale of the partnership assets and liquidation of the partnership would result
in immediate cash distributions to the limited partners and avoid the market
risks associated with the ownership of Canaan common stock.  However, Canaan and
the General Partners believe liquidation of the partnerships is less beneficial
to limited partners primarily because the properties owned by many of the
partnerships consist of small non-operated interests which are not likely to be
valued favorably in the property market, resulting in discounted sale
prices.


          Canaan and the General Partners conducted an analysis of the going
concern and liquidation values of each partnership compared to the Exchange
Value.  Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions -Consideration of Alternatives" beginning on page 78
for a more detailed analysis of the alternatives.


 Appraisal Rights; Investor Lists

          Under Oklahoma law, limited partners of the partnerships are not
entitled to dissenters' rights.  However, pursuant to the rules of the National
Association of Securities Dealers applicable to rollup transactions, limited
partners in each partnership will be entitled to exercise appraisal rights.  The
right of a limited partner to receive a cash payment for their interest in a
partnership equal to the Appraised Value provides limited partners with the
required appraisal rights.

                                       26
<PAGE>

          A limited partner may obtain a list of limited partners in his
partnership by making a written request to the General Partners at 119 North
Robinson, Suite 600, Oklahoma City, Oklahoma 73102.

Accounting Treatment

          The combination transactions are expected to be accounted for as:

          .    A reorganization of entities under common control for the General
               Partners and the partnerships. As a result, the value of the
               assets and liabilities of the partnerships and the General
               Partners will be recorded at their historical cost.

          .    A purchase of Indian. As a result, the purchase price equal to
               the fair value of Indian's assets acquired and liabilities
               assumed will be allocated to the assets and liabilities of Indian
               as of the date of closing of the combination transactions.

          .    A purchase of Canaan Securities. As a result, the purchase price
               equal to the fair value of Canaan Securities' right to receive
               cash distributions and future fees for services based on the
               partnerships' ongoing revenues from oil and gas properties will
               be allocated to the assets and liabilities of Canaan Securities
               based on their estimated values as of the date of closing of the
               combination transactions.

Business After the Completion of the Combination Transactions

          Canaan will become an independent publicly held oil and gas company
after the completion of the combination transactions.

          Canaan will seek growth through an active development drilling
program, identification and development of extension prospects and impact
acquisitions.  The company will utilize in-house geological and engineering
expertise to identify and evaluate prospective locations, whether proved or
unproved.  Canaan will employ aggressive land strategies to increase ownership
in existing properties with development potential and to obtain acreage in areas
of interest through acquisitions, leases or farm-ins.  Canaan will concentrate
its efforts in the Mid-Continent area, with a preference for natural gas
producing properties, and will seek operations whenever possible.

          On a pro forma basis as of December 31, 1999, Canaan will have
interests in 754 gross (132 net) gas wells, 211 gross (60 net) oil wells for a
total of 965 gross (192 net) wells, of which 201 or 21% will be operated by
Canaan.  Its proved reserves will consist of 103.6 Bcfe with an estimated
Present Value of $75.6 million.

                                      -27-
<PAGE>

          Canaan intends to finance its growth through various methods including
public and private offerings of equity and debt securities and bank and other
borrowings.  Canaan expects to complete a public offering of common stock after
closing of the combination transactions when Canaan determines market conditions
are desirable.

Comparative Rights of Security Holders

          For comparison of the rights of Canaan's shareholders under Oklahoma
law and Canaan's certificate of incorporation and bylaws with rights of the
partners of each of the partnerships under Oklahoma law and the respective
partnership agreements, please see "Comparative Rights of Security Holders".


Resales of Canaan Common Stock

          The shares of Canaan common stock that will be issued to limited
partners and the shareholders of Indian in connection with the combination
transactions have been registered under the Securities Act.  All shares of
common stock received by limited partners will be freely tradeable after
completion of the combination transactions.

          The shares of Canaan common stock issued in the combination
transactions to the shareholders of Canaan, the General Partners and Canaan
Securities will not be registered under the Securities Act and may not be sold
unless registered or in transactions exempt from registration.  In addition, all
of the shareholders of Canaan, the General Partners and Canaan Securities and
all but two shareholders of Indian have entered into an agreement granting to
each other reciprocal rights of first refusal in connection with any proposed
sales of Canaan common stock by them, except sales of less than a nominal number
of shares.  The shareholders who are parties to this agreement will collectively
own 42% -60% of Canaan's common stock, depending on the level of limited partner
cash elections.

Conditions to Combination Transactions

          The closing of the combination transactions is conditioned upon, among
other things:

          .    The approval of the Plan of Combination by a majority in interest
               of the limited partners in all of the partnerships.

          .    The absence of any material adverse change affecting any of the
               entities participating in the combination transactions.

          .    No more than $15 million will be required to be paid in cash to
               limited partners electing to receive cash.

Limited partners will own stock in a corporation with perpetual existence rather
than a partnership interest in a limited partnership with a limited life
resulting in material changes in the nature of their investments.

          Limited partners currently own interests in the partnerships which are
subject to a single level of federal and state income taxes at the partner level
and which were organized for the purposes of acquiring producing properties and
making cash distributions to limited partners. The partnerships have a limited
life and a limited purpose.  Upon consummation of the transaction, the limited
partners will become shareholders of a corporation subject to income tax at both
the corporate and shareholder levels with perpetual existence and with a broad
business purpose.  While the rights of limited partners and shareholders are in
some respects similar, there are material differences to the nature of an
investment in a limited partnership and a corporation.

Limited partners have received cash distributions from the partnerships, but
will receive no cash distributions or dividends in the foreseeable future.

          The combination transactions will result in the limited partners
holding shares of our common stock, unless a limited partner elects to receive
cash.  We do not anticipate paying dividends on our common stock in the
foreseeable future.  Limited partners have historically received cash
distributions as described under "Information Concerning the Partnerships -
Selected Historical and Financial Operating Information".

There has been no public market for our common stock and there is no assurance
that a market will develop.  There is no assurance that the value of the Canaan
common stock received by a limited partner will be equal to the Exchange Value.
The Exchange Values are being used solely to determine the relative ownership of
Canaan by the owners of each entity involved and do not represent the fair value
of Canaan or its net assets.

          Our common stock will be listed on the NASDAQ National Market System
but there has been no prior market for our common stock.  The price at which the
common stock will trade will be established by the market and there is no
assurance such price will bear any relationship to the Exchange Value.
Liquidity for our common stock may be limited because the number of holders will
be relatively small.  There may be a large number of shares of our common stock
offered for sale immediately after the closing date for various reasons,
including the liquidity that the combination transactions will afford to limited
partners, who have not had access to a trading market for the partnership
interests and now may wish to liquidate their investment at the

                                      -30-
<PAGE>

first opportunity. The inclusion of the cash election for limited partners may
mitigate some of this risk. However, sales by limited partners may tend to lower
the market price for our common stock.

          A decline in oil or gas prices or depressed conditions in the oil and
gas industry in general could adversely affect the market price of our common
stock.  A downturn in the general economic and stock market conditions or in our
drilling record and production performance or results of our operations that are
lower than expected by the marketplace could also be expected to have a negative
effect on the market price of our common stock.

The consideration limited and general partners receive and the other terms of
the combination transactions were determined by Canaan and the General Partners,
which have inherent conflicts of interest, and may not reflect the value of the
net assets of the respective partnerships if sold to an unaffiliated third party
in an arm's length transaction.

          Canaan and the General Partners determined the Exchange Values of the
partnerships based, in part, on the estimated value of each of the partnerships'
oil and gas reserves as of September 30, 1999 as estimated by Netherland Sewell,
its bank debt and net working capital.  The determination of the Exchange Values
involves a conflict of interest because the General Partners serve as general
partners of the partnerships, their principal shareholders have been involved in
the organization and promotion of the combination transactions, and Canaan will
be allocated additional Exchange Value for its operating rights. Accordingly,
the determination of the Exchange Values may not reflect the allocation of
relative value between the limited partners and the General Partners if the
combination transactions were negotiated with an unaffiliated third party in an
arm's length transaction.

The Exchange Values are based primarily on estimates of oil and gas reserves and
future net cash flows which have inherent uncertainties.  Exchange Values do not
represent fair market value.

          The present value of estimated future net cash flows from oil and gas
reserves is the primary factor considered in determining the Exchange Values.
However, reserves cannot be determined with a high degree of certainty.  There
are numerous uncertainties inherent in estimating quantities of oil and gas
reserves and in projecting future rates of production, future development,
recompletion and workover expenditures, prices to be received upon the sale, and
costs to be incurred in production.  The Reserve Value for each of the entities
involved only represents an estimate and may vary materially from the quantities
of oil and gas actually recovered, and consequently the future net cash flows
received upon the sale thereof.  The use of these estimates in determining the
Exchange Values for the entities involved could therefore result in an
undervaluation or overvaluation of the various entities, including the
partnership interests owned by limited partners.  For these reasons the Exchange
Values do not represent fair market value.

                                      -31-
<PAGE>

The price assumptions used to calculate the Reserve Value will not be modified
for changes in prices which could alter the relative values of the entities
involved in the combination transaction or the relative share of the limited
partners and General Partners which have not achieved payout.

          Canaan and the General Partners established the oil and gas prices
used by Netherland Sewell & Associates to calculate the Reserve Value of the
entities involved in the combination transaction. These prices did not take into
consideration existing hedge transactions which the partnerships and Indian have
entered into which expire on or before December 31, 2000 and which are at prices
different from the prices used to calculate Reserve Value. Further, the Reserve
Value will not be adjusted for any changes in oil and gas prices that occur
subsequent to the Effective Date and prior to the closing date. Although the
Reserve Value of all of the entities should be equally affected by changes in
oil and gas prices, different oil and gas prices from those used to calculate
the Reserve Value would have an effect on the timing of payout in the
partnerships which have not yet achieved payout and thereby affect the
allocation of Reserve Value between the limited partners and the General
Partner. In addition, changes in prices would affect the Exchange Value of the
entities differently because of the differences in relative levels of
indebtedness of these entities.

The alternatives to continuing the partnerships or liquidating their assets
potentially could be more beneficial to limited partners than the combination
transactions.

          Instead of entering into the combination transactions, a partnership
instead could continue to operate, or with the approval of the limited partners
of the partnership, seek to liquidate the partnership's assets and distribute
the liquidation proceeds in accordance with the provisions of the respective
partnership agreement, enabling limited partners to reinvest proceeds from the
asset sales in the case of a liquidation and avoid the market risks associated
with the ownership of Canaan common stock. Please see "Background and Reasons
For the Combination Transactions - Alternatives to the Combination
Transactions".

No independent representative was engaged to represent the limited partners in
negotiating the terms of the combination transactions, which terms may be
inferior to those that could have been negotiated by an independent
representative. Furthermore, no fairness opinion has been obtained regarding the
fairness of the combination transactions.

          We did not engage an independent representative, such as an investment
bank, to negotiate the terms of the combination transactions. As a result, the
Exchange Values and other terms of the combination transactions may not be as
favorable as the terms that an independent representative might have obtained.
In addition, we did not retain an independent third party to render an opinion
with regard to the fairness of the combination transactions to the limited
partners and/or the partnerships.

                                      -32-
<PAGE>

The cash being offered to limited partners who elect to receive cash is intended
to approximate the fair market value of their interests in a partnership, but
there is no assurance such value is in fact fair market value.

          A limited partner may elect to receive cash equal to the Appraised
Value of his partnership interest, which is based on an appraisal of the
partnership's oil and gas properties by an independent appraiser. This appraisal
represents an opinion and the Appraised Value may or may not represent the fair
market value of the limited partner's interest in the partnership. The cash
election is being offered as a means for limited partners who do not wish to
bear the market risk associated with ownership of Canaan common stock to receive
cash in lieu thereof and to meet a requirement of the National Association of
Securities Dealers that limited partners be offered the right to receive
Appraised Value.

The combination transactions will reduce and dilute a limited partner's voting
rights.

          The combination transactions will result in each limited partner
receiving a smaller proportionate ownership interest in Canaan than the interest
such partner owns in the partnership. This will reduce a limited partner's
ability to influence the taking of action in those instances where the
partnership agreements provide for the vote or consent of limited partners.

The combination transactions will result in a limited partner being exposed to
risks of a larger enterprise without restrictions on leverage.

          Each of the partnerships acquired specific producing properties and
they have not engaged in material additional development activities. The limited
additional development that has been conducted by the partnerships was financed
using borrowings which under the terms of each of the partnership agreements was
limited to 20-30% of original capital contributions. After the combination
transactions, Canaan will engage in additional oil and gas property acquisitions
and development drilling without any specific limitations on the amount of
leverage that may be incurred to conduct its activities. As of December 31,
1999, the level of indebtedness in partnerships ranged from 9% to 39% of the
present value of estimated future net revenues from proved reserves, whereas
Canaan's pro forma percentage was 42%. While the limited partners in an
individual partnership will reduce the risk of ownership of specific properties
by obtaining an indirect ownership interest in a more diversified group of
properties, they will forsake the economic benefit of any extraordinary increase
in value attributable to the specific oil and gas properties now held by their
individual partnerships. In addition, the additional property acquisition and
development activities will expose limited partners to all of the risks
associated with the conduct of those activities and the absence of any
limitation on the amount of leverage that may be incurred by Canaan exposes its
shareholders to greater risk than exists in the partnerships.

                                      -33-
<PAGE>

The 1996 and 1996-I partnerships' failure to approve the combination
transactions may result in a material adverse effect on returns to limited
partners due to the loss of a $3 million upward adjustment in the Indian
Contingent Production Payment.

          In connection with the negotiation of the acquisition agreement
between Indian and Canaan, Indian agreed that its Exchange Value would be
reduced by its production payment obligation to the 1996 and 1996-I Partnerships
in consideration of such partnerships advancing to Indian a total of $6 million
in exchange for a "Contingent Production Payment" from Indian to the
partnerships payable at the rate of $56,250 per month until paid in full. The
Contingent Production Payment is $9 million if the combination transactions are
consummated and $6 million if they are not. The 1996 share of the Contingent
Production Payment is 53% and the 1996-I share of the Contingent Production
Payment is 47%. If the combination transactions are not consummated, Indian is
expected to be liquidated and proceeds of liquidation after payment of all
obligations to be shared 50% by the Indian shareholders and 50% by the Coral
Group. Accordingly, if the combination transactions are consummated, the 1996
and 1996-I partnerships may not receive any gain or return on the amount of
their investments in the Contingent Production Payment. The payment of this
obligation is subordinate to Indian's obligations to its bank lenders and
depending upon the amount of liquidation proceeds, the Contingent Production
Payment may not be paid in full. The amount invested in the Contingent
Production Payment represented 33% of the initial capital of the 1996
partnership and 43% of the initial capital of the 1996-I partnership.

We have not requested a ruling from the IRS on the tax consequences of the
combination transactions and the IRS may disagree with the opinion of our
counsel on the tax consequences.

          Canaan has received an opinion of counsel relating to material income
tax consequences of the combination transactions. However, counsel has not
expressed an opinion on all consequences. No rulings have been, or will be,
requested from the IRS with respect to the tax consequences resulting from the
proposed combination transactions and, accordingly, we can give no assurance
that the IRS or the courts would agree with the opinion described in "Material
Federal Income Tax Consequences."

          The partnerships presently are taxed as limited partnerships and, as
such do not generally pay federal income tax at the partnership level. Rather,
the items of income, gain, loss and deduction flow through to their partners.
The limited partners will receive Canaan common stock in the proposed
combination transactions. Because Canaan is a corporation, its income will be
taxed at the corporate level and, to the extent distributions are made to its
shareholders, such distributions will be taxable to the shareholders to the
extent of Canaan's accumulated and current earnings and profits. As a result of
the proposed combination transactions, the former limited partners who become
Canaan shareholders will no longer receive the pass-through tax treatment
accorded to partners.

If the combination transactions are not approved, limited partners in each
partnership will bear a portion of the transaction expenses.

          The transaction and fees and expenses incurred in connection with the
proposed combination transactions will be allocated to the limited partnerships
in proportion to their relative Exchange Values. The General Partner will bear a
portion of the fees allocated to the partnership equal to its percentage
interest in the partnership operating costs plus a percentage equal to the
percentage of limited partners who abstain or vote against the combination
transactions. The limited partners will bear a percentage of the allocated
expenses in proportion to the percentages of limited partners who voted to
approve the combination transactions. The estimated expenses allocatable to the
limited partnerships range from an estimated $25,500 for the low value
partnerships to $187,000 for the highest value partnership. The maximum expenses
chargeable to the limited partners in any partnership if the combination
transactions are not approved range from approximately $19,000 in the lowest
value partnership to approximately $168,000 in the highest value partnership.
Please see "The Combination Transactions - Expenses and Fees".

Risks Related to Canaan

Our future performance depends upon our ability to find or acquire additional
oil and gas reserves that are economically recoverable.

          Unless we successfully replace the reserves that we produce, our
reserves will decline, resulting eventually in a decrease in oil and gas
production and lower revenues and cash flow from operations. While we believe
that we can replace reserves through drilling and acquisitions, we may not be
able to replace such reserves at acceptable costs. The business of exploring
for, developing or acquiring reserves is capital intensive. We may not be able
to make the necessary capital investment to maintain or expand our oil and gas
reserves if cash flow from operations is reduced, due to lower oil and gas
prices or otherwise, or if external sources of capital become limited or
unavailable. In addition, our drilling activities will be subject to numerous
risks, including the risk that no commercially productive oil or gas reserves
will be encountered. Exploratory drilling involves more risk than development
drilling because exploratory drilling is designed to test formations for which
proved reserves have not been discovered.

          Although we will continually identify and evaluate acquisition
opportunities, we cannot assure you that we will successfully consummate any
acquisition, that we will be able to acquire producing oil and gas properties
that contain economically recoverable reserves or that any acquisition will be
profitably integrated into our operations.

We are subject to anti-takeover provisions in our charter that could delay or
prevent an acquisition of our company, even if such an acquisition would be
beneficial to our shareholders.

          Our certificate of incorporation, our bylaws, Oklahoma law and
management contracts contain provisions which could make it more difficult for a
third party to acquire us even if doing so might be beneficial to our
shareholders. These provisions include:

          .    A classified board, the members of which serve staggered three-
               year terms and may be removed by shareholders only for cause;

          .    A prohibition on shareholders calling special meetings and acting
               by written consent;

          .    A requirement for advance notice of shareholder proposals and
               director nominations; and,

          .    Restrictions on business combinations with interested
               shareholders and limitations on voting power of control share
               acquisitions.

          .    Contracts providing severance benefits to management of a change
               in control.

Please see "Management - Change in Control Agreements" and "Description of
Securities."

If we are unable to retain and hire senior management and key employees, it will
have a material impact on us.

          As we continue to grow, we will need to hire additional personnel in
all areas. In order to be successful, we must attract, retain and motivate key
employees and we face significant competition from other oil and gas companies
in doing so. We may be unable to retain our key employees or retain other
qualified employees in the future. Please see "Management" for detailed
information on our senior management.

Investors will be relying on our board and management judgment regarding the
future directions and activities of the company.

          Our management and board of directors will have broad discretion with
respect to the future activities of Canaan and limited partners will be relying
on a judgment of our management regarding our activities. The Board and
management will be responsible for making all decisions regarding the
acquisition and development of additional unspecified oil and gas properties and
the general manner in which the Company is operated. Please see "Information
concerning Canaan - Business after the Combination Transactions".

                                      -36-
<PAGE>

We will need additional financing to grow and our ability to raise further
financing is uncertain.

          After completion of the combination transactions, we anticipate that
our cash flow from operations will be sufficient to meet our anticipated working
capital and debt service requirements, but such cash flow may not be sufficient
to finance significant growth through additional acquisitions or drilling. On a
pro forma basis, Canaan will have 110 undeveloped locations containing proved
reserves with an estimated present value as of December 31, 1999 of $9,178,700.
Costs to develop these reserves are estimated at $13,125,600 over a seven-year
period. Upon the completion of the combination transactions, we anticipate
seeking additional equity financing by an underwritten public offering of common
stock at such time as we believe market conditions are appropriate. There is no
assurance we will complete such an offering. We may pursue alternative sources
of financing through private placements of equity or debt securities or through
asset sales. If financing is not obtained, we may not be able to develop all of
our reserves.

          If additional funds are raised through the issuance of equity or
convertible securities, the percentage ownership of our shareholders will be
reduced and these newly issued securities may have rights, preferences or
privileges senior to those of existing shareholders, including those receiving
shares in the combination transactions. We cannot assure you that additional
financing will be available on terms favorable to us or at all. If adequate
funds are not available or not available on acceptable terms, our ability to
fund our operations and take advantage of unanticipated opportunities will be
significantly limited.

Risks Related to the Oil and Gas Industry

A substantial decrease in oil and gas prices would have a material impact on us.

          Our future financial condition and results of operations are dependent
upon the prices we receive for our oil and gas production. Oil and gas prices
historically have been volatile and likely will continue to be volatile in the
future. This price volatility also affects our common stock price. We cannot
predict oil and gas prices and such prices may decline in the future. The
following factors have an influence on oil and gas prices:

          .    relatively minor changes in the supply of and demand for oil and
               gas;

          .    weather conditions;

          .    market uncertainty;

          .    domestic and foreign governmental regulations;

          .    the availability and cost of alternative fuel sources;

                                      -37-
<PAGE>

          .    the domestic and foreign supply of oil and gas;

          .    the price of foreign oil and gas;

          .    political conditions in oil and gas producing regions, including
               the Middle East; and

          .    overall economic conditions.

Estimating our reserves and future net cash flows is difficult to do with any
certainty.

          There are numerous uncertainties inherent in estimating quantities of
proved oil and gas reserves and their values, including many factors beyond our
control. The reserve data included in this document represents only estimates.
Reserve engineering is a subjective process of estimating underground
accumulations of oil and gas that cannot be measured in an exact manner. The
accuracy of any reserve estimate is a function of the quality of available data,
the precision of the engineering and geological interpretation, and judgment. As
a result, estimates of different engineers often vary. The estimates of
reserves, future cash flows and present value are based on various assumptions,
including those prescribed by the SEC, and are inherently imprecise. Actual
future production, cash flows, taxes, development expenditures, operating
expenses and quantities of recoverable oil and gas reserves may vary
substantially from our estimates. Also, the use of a 10% discount factor for
reporting purposes may not necessarily represent the most appropriate discount
factor, given actual interest rates and risks to which our business or the oil
and gas industry in general are subject.

          Quantities of proved reserves are estimated based on economic
conditions, including oil and gas prices in existence at the date of assessment.
Our reserves and future cash flows may be subject to revisions, based upon
changes in economic conditions, including oil and gas prices, as well as due to
production results, results of future development, operating and development
costs, and other factors. Downward revisions of our reserves could have an
adverse effect on our financial condition and operating results.

We may incur write-downs of the net book values of our oil and gas properties
which would adversely affect our shareholders equity and earnings.

          The full cost method of accounting which we follow requires that we
periodically compare the net book value of our oil and gas properties, less
related deferred taxes, to a calculated "ceiling". The ceiling is the estimated
after-tax present value of the future net revenues from proved reserves using a
10% discount rate and using constant prices and costs. Any excess of net book
value of oil and gas properties is written off as an expense and may not be
reversed in subsequent periods even though higher oil and gas prices may have
increased the ceiling in these periods. A write-off constitutes a charge to
earnings and reduces shareholders equity, but does not

                                      -38-
<PAGE>

impact our cash flows from operating activities. Future write-offs may occur
which would have a material adverse effect on our net income in the period
taken, but would not affect our cash flows.

Operational risks in our business are numerous and could materially impact us.

          Our operations will involve operational risks and uncertainties
associated with drilling for, and production and transportation of, oil and gas,
all of which can affect our operating results. Our operations may be materially
curtailed, delayed or canceled as a result of numerous factors, including:

          .    the presence of unanticipated pressure or irregularities in
               formations;

          .    accidents;

          .    title problems;

          .    weather conditions;

          .    compliance with governmental requirements; and

          .    shortages or delays in the delivery of equipment.

          Also, our ability to market oil and gas production depends upon
numerous factors, many of which are beyond our control, including:

          .    capacity and availability of oil and gas systems and pipelines;

          .    effect of federal and state production and transportation
               regulations; and

          .    changes in supply and demand for oil and gas.

We do not insure against all potential losses and could be materially impacted
by uninsured losses.

          Our operations will be subject to the risks inherent in the oil and
gas industry, including the risks of fire, explosions, blow-outs, pipe failure,
abnormally pressured formations and environmental accidents, such as oil spills,
gas leaks, salt water spills and leaks, ruptures or discharges of toxic gases.
If any of these risks occur in our operations, we could experience substantial
losses due to:

          .    injury or loss of life;

                                      -39-
<PAGE>

          .    severe damage to or destruction of property, natural resources
               and equipment;

          .    pollution or other environmental damage;

          .    clean-up responsibilities;

          .    regulatory investigation and penalties; and

          .    other losses resulting in suspension of our operations.

          In accordance with customary industry practice, we maintain insurance
against some, but not all, of the risks described above. The occurrence of an
uninsured loss could have a material adverse effect on our financial condition
or results of operations.

Governmental and environmental regulations could adversely affect our business.

          Our business will be subject to certain foreign, federal, state and
local laws and regulations on taxation, the exploration for and development,
production and marketing of oil and gas, and environmental and safety matters.
Many laws and regulations require drilling permits and govern the spacing of
wells, rates of production, prevention of waste and other matters. Such laws and
regulations have increased the costs of planning, designing, drilling,
installing, operating and abandoning our oil and gas wells and other facilities.
In addition, these laws and regulations, and any others that are passed by the
jurisdictions where we have production, could limit the total number of wells
drilled or the allowable production from successful wells which could limit our
revenues.

          Our operations will be subject to complex environmental laws and
regulations adopted by the various jurisdictions where we operate. We could
incur liability to governments or third parties for any unlawful discharge of
oil, gas or other pollutants into the air, soil or water, including
responsibility for remedial costs. We could potentially discharge these
materials into the environment in any of the following ways:

          .    from a well or drilling equipment at a drill site;

          .    leakage from gathering systems, pipelines, transportation
               facilities and storage tanks;

          .    damage to oil and gas wells resulting from accidents during
               normal operations; and

          .    blowouts, cratering and explosions.

                                      -40-
<PAGE>

          Because the requirements imposed by all of the laws and regulations
relating to our business are frequently changed, we cannot assure you that laws
and regulations enacted in the future, including changes to existing laws and
regulations, will not adversely affect our business. In addition, because we may
acquire interests in properties that have been operated in the past by others,
we may be liable for environmental damage caused by such former operators.

Competition in the oil and gas industry is strong and can harm our business.

          The oil and gas industry is highly competitive. We will compete in the
areas of proved reserve and undeveloped acreage acquisitions and the
development, production and marketing of oil and gas, as well as contracting for
equipment and recruiting and retaining qualified employees. Our competitors
include major oil and gas companies, other independent oil and gas concerns, gas
marketing companies, and individual producers and operators. Most of our
competitors have financial and other resources which substantially exceed those
which are available to us. Competition in the regions in which we own properties
may result in occasional shortages or unavailability of drilling rigs and other
equipment used in drilling activities, as well as limited availability of and
access to pipelines. Competitive circumstances could result in curtailment of
activities, increased costs, delays or losses in production or revenues, or
cause interests in oil and gas leases to lapse. All of the competitive
influences could have a material adverse impact on our operations and
profitability.

              BACKGROUND AND REASONS FOR COMBINATION TRANSACTIONS

Background of Partnerships

          Each of the partnerships was organized by the General Partners for the
purpose of acquiring interests in producing oil and gas properties and to engage
in drilling of development and offset wells, for the reworking, recompletion,
deepening or plugging back of existing wells and secondary or tertiary recovery
operations and other production enhancement techniques incident to the operation
of producing properties acquired by the partnerships. The partnerships were not
organized to engage in exploratory drilling activities. The objective of each of
the partnerships is to provide cash distributions generated by the sale of oil
and gas from the properties acquired. Each of the partnerships raised capital in
private offerings from limited partners, primarily individuals and substantially
all of whom are considered "accredited investors" under the federal securities
laws. In each of the partnerships, Leo E. Woodard and John Penton, officers and
shareholders of Canaan, serve as "Additional General Partners". As provided by
the terms of each partnership, the General Partner and Additional General
Partners did not make any capital contributions for their interests in the
partnership.

          All of the funds invested by limited partners have been invested in
oil and gas properties as contemplated by the partnership agreements, after
required payments of organization and offering costs. Properties acquired by

          Neither Canaan, the General Partners nor Canaan Securities have
experienced since January 1, 1998, or is likely to experience, any material
adverse financial development. All of the partnerships except the 1995
partnership have incurred significant indebtedness in order to finance limited
development activities. Through March 31, 2000, all of the partnerships have
generally paid interest only on such borrowings and no material principal
payments have been made because the collateral value of each partnership's oil
and gas properties has been substantially more than required by the
partnership's lender. In some of the partnerships, the level of debt in relation
to the collateral value of the partnership's oil and gas properties is
sufficiently high that repayment of principal of the debt will need to be
commenced in 2000 if the combination transactions do not occur. The partnerships
likely to require debt repayment are the 1990 and 1991 partnerships.
Commencement of principal payments on indebtedness of these partnerships will
reduce cash distributions to limited partners in these partnerships, and limited
partners will also be required to report as income their share of partnership
principal repayments. If the combination transactions are consummated, the
partnerships' debt will be paid by Canaan.

                                      -42-
<PAGE>

          Each partnership has a specified term of existence of 20 years and
could be terminated earlier upon recommendation of the General Partner with
approval of the majority-in-interest of limited partners. At the time the
partnerships were organized, there were no specific plans to terminate any
partnership on the occurrence of any specific events.

Background of Combination Transactions

          The partnerships were formed between 1990 and 1996. As contemplated
when the partnerships were organized, the oil and gas production from the
producing properties owned by the older partnerships has steadily declined over
time. These reductions are due to the natural decline occurring in connection
with the depletion of oil and gas properties. These production declines have
contributed to a reduction in cash distributions, particularly in the earlier
partnerships. Similar production declines can be expected from the recently
formed 1996 and 1996-I partnerships in the future. Please see "Information
Concerning the Partnerships - Selected Historical Financial and Operating Data
for Individual Partnerships".

          In 1997, Canaan and the General Partners began to consider the
possibility of combining the partnerships in order to achieve the benefits of a
corporate entity with a larger asset base and greater growth potential than
available to the General Partners or any individual partnership. Actions to
implement the Plan were not taken at that time pending the closing of the
offering of partnership interests for the 1996 and 1996-I partnerships and the
investment of the capital contributions in oil and gas properties.

          In evaluating the possible combination of the partnerships into a
publicly traded corporation, management of Canaan considered whether the size of
the combined partnerships would be sufficient to attract a market following and
determined it would be desirable to include additional oil and gas properties in
the new entity. Canaan sought another company to join in the transaction and
management became aware that Indian was considering a possible sale or business
combination from information provided to them by employees of Indian. Canaan and
Indian executed an acquisition agreement in February 1999 providing for Indian
to be included in the combination transactions with Indian and the Coral Group
to receive shares of the new entity based on their relative Exchange Values. In
order to induce Indian to make this agreement, the 1996 and 1996-I partnerships
advanced to Indian a combined sum of $6 million. The partnerships received in
exchange a Contingent Production Payment from Indian payable out of production
revenues at the rate of $56,250 per month until paid in full. The Contingent
Production Payment is $9 million if the combination transactions are consummated
and $6 million if they are not, less any payments previously made. At the same
time, Indian and Canaan entered into a management agreement providing for Canaan
to manage the business of Indian subject to the control of Indian's board of
directors.

<PAGE>

          After the execution of the Indian acquisition agreement and the full
investment of the 1996 and 1996-I partnerships, Canaan and the General Partners
began the process of evaluating the combination transactions and reviewing the
oil and gas properties of all of the entities involved to prepare them for a
reserve evaluation by Netherland Sewell. Canaan also engaged Crowe & Dunlevy, a
Professional Corporation, Oklahoma City, Oklahoma, as legal counsel and KPMG
LLP, as independent certified public accountants, to audit the financial
statements of Canaan in connection with the transaction. Neither Crowe & Dunlevy
nor KPMG LLP had any prior relationship with Canaan, the General Partners, the
partnerships or Canaan Securities. Crowe & Dunlevy also had no prior
relationship with Indian. KPMG LLP has served as independent auditors of
Indian's financial statements since 1991.

Reasons for the Combination Transactions

          Canaan and the General Partners recommend that the limited partners in
each of the partnerships vote in favor of the combination transactions. In
considering the combination transactions, Canaan and the General Partners took
into account various advantages and disadvantages of the combination
transactions to each of the partnerships and its respective limited partners.
The advantages they considered included:

          .    Canaan believes that shares of publicly held oil and gas
               companies generally trade at values greater than their cash
               liquidation values, affording limited partners potentially
               greater value than represented by the cash value of the
               partnership's oil and gas properties, either in immediate
               liquidation or in continuing the partnership. Canaan believes
               that publicly-held oil and gas companies generally trade at
               premiums to their potential cash liquidation values due to value
               attributable to going concern and potential growth and due to the
               fact that public company stock valuations do not reflect
               discounts for nonproducing reserves typically applied in cash
               transactions.

          .    The partnerships may not have the cash nor the ability to borrow
               funds necessary to develop their non-producing reserves. This may
               result in reduction or temporary suspension of cash distributions
               in order to participate in proposals to place these non-producing
               reserves on production, or the partnerships may be forced to
               forego participation in these proposals.

          .    The continuation of the partnerships will likely result in
               declining cash distributions to limited partners as a result of
               the natural depletion of each of the partnership's oil and gas
               properties and the requirement that partnerships, other than the
               1995 partnership, repay borrowings with cash flow otherwise
               distributable to partners.

                                      -44-
<PAGE>


          .    The combination transactions permit the limited partners to
               participate in an investment in a larger company with a more
               diversified property base and a potential for growth and
               appreciation in the future. Each partnership owns interests in 52
               to 163 gross wells whereas, on a pro forma basis as of December
               31, 1999, Canaan will have interests in 965 gross (192 net)
               wells.

          .    For limited partners whose investment is based on the potential
               for increases in oil or gas prices, ownership of stock in a
               publicly traded oil and gas company continues to afford an
               opportunity to benefit indirectly from these price increases.

          .    The structure of the transaction gives limited partners the
               opportunity to exchange their interest in the partnerships for
               Canaan common stock without immediate tax consequences or to
               receive cash in a taxable transaction if they do not wish to
               receive Canaan common stock.

          .    The ownership of common stock in a publicly traded company will
               afford those limited partners the opportunity to liquidate their
               investment should they desire to do so.

          .    The organization of a publicly held oil and gas company will
               potentially afford access to capital and other resources that
               will provide Canaan opportunities for future growth that are not
               available in the partnerships or the other entities.

          .    The inclusion of Indian in the combination transactions adds
               reserves in the same areas as reserves owned by the Coral Group
               and enhances Canaan's reserve base and property ownership. Indian
               and the Coral Group are being valued in a consistent manner for
               purposes of the combination transactions.

          .    For the 1996 and 1996-I partnerships, the terms of the Indian
               Contingent Production Payment obligations to them effectively
               provide an enhanced return compared to the return such
               partnerships could realistically achieve if the combination
               transactions are not consummated.


          Canaan and the General Partners also considered disadvantages of the
combination transactions that included:

          .    Limited partners will own stock in a corporation which is a
               different investment objective from investing in a partnership
               designed to generate recurring cash distributions. However, the
               cash election is intended to provide limited partners the option
               to receive cash if they prefer.

                                      -45-
<PAGE>

          .    Limited partners will no longer receive cash distributions.
               However, most limited partners are high income or high net worth
               individuals classified as "accredited investors" under the SEC
               rules and are likely to be less dependent on partnership cash
               distributions than individuals with lower incomes or net worths.

          .    Canaan will engage in the acquisition and exploitation of new oil
               and gas properties which will expose limited partners to all of
               the attendant risks associated with such activities. The
               partnerships generally do not conduct significant drilling
               activities, but own producing properties. The activities of
               Canaan may, therefore, involve greater risks than the activities
               of the partnerships, but also offer the potential for additional
               benefits if the acquisition and exploitation activities are
               successful.

          .    Increases in prices for oil and gas may have a more direct effect
               on limited partners in the partnerships due to the immediate
               effect on potential cash distributions. However, Canaan and the
               General Partners believe that an increase in oil and gas prices
               will also have an indirect beneficial effect on the market price
               for Canaan common stock.

          .    Limited partners will become subject to the volatility of the
               market value of Canaan common stock. Market factors that may
               affect the common stock price will include factors other than
               those that affect the value of a limited partner's interest in a
               partnership, such as general market conditions.


          .    Canaan will incur the costs required to maintain its status as a
               reporting company under the Exchange Act listed on the NASDAQ
               National Market System. These costs will likely exceed the
               continuing administrative costs which would be incurred by the
               partnerships if they continue in existence.

          Canaan and the General Partners also considered the advantages and
disadvantages of the combination transactions for individual partnerships as
described below:

          .    None of the individual partnerships have a concentrated
               investment in a single property or group of properties that
               exposes any partnership to the individual risks and potential
               benefits of ownership of a property that might be materially
               different from the properties owned by any other partnership.


          .    The 1995 Partnership does not have any significant bank
               indebtedness whereas the other partnerships have bank
               indebtedness ranging from 9% to 39% of present value of reserves
               as of December 31, 1999. If the 1995 Partnership were continued
               and it did not borrow funds in the future for development costs,
               its partners would continue to receive cash distributions

                                      -46-
<PAGE>


               without a requirement to amortize bank indebtedness as exists in
               the remaining partnerships unless the 1995 partnership incurs
               significant debt for development drilling or other purposes.
               Therefore, the continuation of the 1995 Partnership might not
               result in a reduction in cash distributions to limited partners
               for debt service unless additional indebtedness is incurred.

          .    The terms of the Indian Contingent Production Payment obligation
               to the 1996 and 1996-I partnerships effectively provide an
               enhanced return compared to the return such partnerships could
               realistically achieve if the combination transactions are not
               consummated. The terms of such obligation increase the Exchange
               Value of the 1996 partnership by 21% and the 1996-I partnership
               by 23% over the Exchange Value without the Contingent Production
               Payment.

          .    Except the 1996 partnership, the Exchange Value for all
               partnerships plus historical cash distributions is more than 115%
               of the limited partners' original investment. Because the 1996
               partnership was formed later and its cash distributions to
               limited partners have been less, Canaan and the General Partners
               agreed to reduce their share of the Exchange Value in the 1996
               partnership so that the limited partners receive at least 115% of
               their original investment from the Exchange Value plus prior cash
               distributions so that the limited partners will receive value in
               this form closer to that received by limited partners in the
               other partnerships. For the same reason, the Appraised Value plus
               prior cash distributions for the 1996 and 1996-I partnerships
               will be at least 110% of a limited partner's original investment
               for a cash electing partner.

          Canaan and the General Partners are proposing the combination
transactions at this time because

          .    The size of the combined partnerships and Indian are, in their
               opinion, sufficient to become an independent oil and gas company
               that will gain some market following in the public securities
               markets;

          .    Oil and gas company stocks are trading at relatively favorable
               levels primarily due to relatively high commodity prices; and


          .    Deferring the combination transactions will result in a resulting
               entity of smaller size due to depletion of reserves and cash
               distributions to partners.

          The combination transactions are structured as an exchange of
partnership interests or stock of all of the entities involved for stock in
Canaan because, in the opinion of Canaan and the General Partners:

                                      -47-
<PAGE>


          .    The most common form of organization for a publicly held
               independent oil and gas company is a corporation;

               Including all of the partnerships in the combination transaction,
               rather than only some, treats all partnerships the same and
               maximizes the size of the resulting entity;

          .    Structuring the combination transactions by vote of the limited
               partners permits the combination transactions to be consummated
               by a majority vote; and

          .    The structure is designed to be tax-free to the owners of all
               entities, except limited partners electing to receive cash.

          Canaan and the General Partners have given consideration to
alternatives of continued operation of the partnerships for a longer period or
the possibility of selling the partnership assets and liquidation of the
partnerships prior to proposing the combination transactions to limited partners
for their approval. See "Recommendation of the General Partners and Fairness of
the Combination Transactions" for a complete discussion of these alternatives.


Other Transactions

          Since January 1, 1997, there have been no contacts, negotiations or
transactions concerning any of the following matters relating to the
partnerships, except the contacts, negotiations and transactions with respect to
the Indian acquisition described above:

          .    A merger, consolidation or combination of any of the
               partnerships;

          .    An acquisition of any of the partnerships or of a material amount
               of any of their assets;

          .    A tender offer for or other acquisition of securities of any
               class issued by any of the partnerships; or

          .    A change in control of any of the partnerships.

                         THE COMBINATION TRANSACTIONS

 Description of the Combination Transactions

          The combination transactions consist of:

          .    The acquisition of all of the limited partners' and additional
               general partners' interests in each of the partnerships by Canaan
               by a merger between each partnership and acquisition corporations
               organized by Canaan for purposes of the transaction;

          .    The acquisition of 100% of the stock of the General Partners of
               the partnerships by Canaan;

          .    The acquisition of 100% of the stock of Indian by Canaan;

          .    The acquisition of 100% of the stock of Canaan Securities by
               Canaan; and

          .    An increase in Canaan's outstanding common stock held by its
               current shareholders to result in the appropriate number of
               shares outstanding based on Canaan's relative share of the total
               Exchange Value.

          As a result of the combination transactions, the partnerships, the
General Partners, Indian and Canaan Securities will be wholly-owned subsidiaries
of Canaan. We refer to Canaan, the General Partners, Indian, the partnerships
and Canaan Securities as the "Combining Entities".

          A total of 5,000,000 shares of Canaan common stock will be issued and
be outstanding after the combination transactions, less the number of shares
otherwise issuable to limited partners who elect to receive cash. The owners of
each of the Combining Entities will receive shares of Canaan common stock in
proportion to the "Exchange Value" of such entity relative to the total Exchange
Value of all Combining Entities. The Exchange Value has been determined by
Canaan and is based on a valuation of each Combining Entity's oil and gas
reserves and other assets and liabilities. The Reserve Values were determined by
Netherland, Sewell & Associates, an independent petroleum engineering and
consulting firm, using the same price, cost, effective date and discount rate
assumptions for each entity. A limited partner in any partnership may also elect
to receive cash equal to the "Appraised Value" of his interest in the
partnership.

The Plan of Combination and Indian Acquisition Agreement

          In February 1999, Canaan and the General Partners entered into an
agreement for Canaan to acquire Indian based on their relative Exchange Values
simultaneously with the consummation of the remaining portions of the
combination transactions. We refer to this agreement as the "Indian Acquisition
Agreement". Because the details of the combination

                                      -49-
<PAGE>

transactions had not been finalized at the time of execution of the Indian
Acquisition Agreement, the Combining Entities subsequently entered into the
"Plan of Combination" in February 2000, which supplements the Indian Acquisition
Agreement and provides for the details of the combination transactions. The Plan
of Combination was amended in May 2000 to modify certain terms after Canaan
received comments from the Securities and Exchange Commission on a preliminary
filing of this document.

          Copies of the Indian Acquisition Agreement and the Plan of
Combination, as amended, have been filed as exhibits to the registration
statement of which this document is a part, are incorporated in this document by
reference and are available to limited partners upon request to Canaan at 119 N.
Robinson, Suite 600, Oklahoma City, Oklahoma 73102, (405) 232-3222.

          The Indian Acquisition Agreement obligated the Coral Group to advance
to Indian the sum of $6 million in return for a contingent production payment
("the Contingent Production Payment") payable out of Indian's oil and gas
production proceeds at the rate of $56,250 per month until paid in full.  The
1996 partnership provided 53% of the $6 million in funding and the 1996-I
partnership provided 47% of the $6 million in funding.  The Indian Acquisition
Agreement provides that for purposes of calculating the Exchange Values, the
Indian Exchange Value will be adjusted downward by the remaining amount of the
Contingent Production Payment obligation as of the Effective Date, plus an
additional $3 million and the Exchange Values for the 1996 and 1996-I
partnerships will be adjusted upward by the same amount.

          If the combination transactions do not occur, the Indian Acquisition
Agreement provides that the Contingent Production Payment remains at $6 million,
less any payments previously made, and Indian will be liquidated, with the
proceeds of the liquidation after payment of all liabilities, including the
Contingent Production Payment, to be shared 50% by the shareholders of Indian
and 50% by the Coral Group.

          Simultaneously with the execution of the Indian Acquisition Agreement,
Indian entered into a management agreement with Canaan providing for Canaan to
manage the business of Indian pending the consummation of the combination
transactions subject to the control of Indian's board of directors with respect
to specified matters.  The management agreement provides for Canaan to be
responsible for the day to day operations of Indian, including the authority to
make employment hiring and termination decisions and to manage the collection of
Indian's revenues and payment of Indian's obligations and expenses.  The
management agreement reserved authority to Indian's board of directors to
approve:

          .    Any sales of Indian's oil and gas properties except as
               contemplated by the Indian Acquisition Agreement;

          .    Actions that would change or substantially expand or enlarge the
               business of Indian;

                                      -50-
<PAGE>

          .    The conduct of any exploratory or development drilling;

          .    Any agreement to create liens on Indian's oil and gas properties
               or refinance any of its indebtedness;

          .    Loans to any person from the funds of Indian;

          .    The use of insurance proceeds received upon a total or
               substantial destruction of Indian's oil and gas properties in any
               manner other than may be dictated by any of Indian's loan
               agreements;

          .    Execute or deliver any assignment to the benefit of creditors of
               Indian, confess a judgment against Indian or do any act that
               would make it impossible to carry on the ordinary business of
               Indian;

          .    Any act that would subject a shareholder or member of the board
               of directors of Indian to personal liability; or

          .    Any changes in the terms of the Indian Acquisition Agreement or
               any action which would cause Indian to be in default or in breach
               of any of its representations, warranties or obligations under
               the Indian Acquisition Agreement.

          In order to carry out the management agreement, Leo E. Woodard,
chairman and chief executive officer of Canaan was appointed as president of
Indian and John K. Penton, president of Canaan was appointed as executive vice
president of Indian.

Effective Time of the Combination Transactions

          Closing of the combination transactions. Unless the Combining Entities
otherwise agree, the closing of the combination transactions will occur on the
first business day after the date on which all closing conditions have been
satisfied or waived. The closing of the combination transactions is expected to
take place immediately after the approval of the combination transactions by the
partnerships at the special meeting.

          Effective time of the combination transactions. At the closing,
certificates of merger for the partnership mergers into separate acquisition
corporations organized by Canaan, and a certificate of acquisition for the share
acquisition of Indian by Canaan will be filed with the Oklahoma Secretary of
State and the mergers and share acquisition will be effective at the time the
certificates are so filed. Simultaneously, Canaan will acquire 100% of the stock
of the General Partners and Canaan Securities, and Canaan's existing common
stock will be reclassified.

                                      -51-

          Surviving corporation. Canaan will be the parent company of the other
Combining Entities. Indian, the partnerships, the General Partners and Canaan
Securities will become wholly-owned subsidiaries of Canaan. The certificate of
incorporation and bylaws of Canaan in effect immediately prior to the closing
will be the certificate of incorporation and bylaws of the surviving entity. See
"Comparison of Security Holder Rights".

          The initial directors and senior executive officers of Canaan
following the combination transactions will be as described in "Management".


Consideration to be Received in the Combination Transactions.

          A total of 5,000,000 shares of Canaan common stock will be issued and
outstanding immediately after the combination transactions, less the number of
shares otherwise issuable to limited partners in the partnerships who elect to
receive cash. The owners of each of the Combining Entities will receive shares
of Canaan common stock in proportion to the Exchange Value of such entity
relative to the total Exchange Value of all Combining Entities. Placing Brokers
will receive cash equal to 40% of their Exchange Value and their share of Canaan
common stock will be determined based on the balance of their Exchange Value.


Issuance of Shares; Fractional Shares

          Exchange agent. Prior to consummation of the combination transactions,
Canaan will appoint UMB Bank, N.A., Kansas City, Kansas or another exchange
agent reasonably acceptable to Canaan to effect the issuance of certificates
representing shares of Canaan common stock in the combination transactions.

          Issuance of shares. The owners of the Combining Entities other than
limited partners in the partnerships will receive certificates for Canaan common
stock issuable in the combination transactions at the closing in exchange for
the surrender of the certificates of stock in the Combining Entities. Canaan
common stock will be issued to a limited partner in the partnerships by the
exchange agent as soon as the limited partner has submitted a properly completed
and signed proxy and cash election form and letter of transmittal. The proxy and
cash election form and letter of transmittal is being provided to limited
partners with this document and should be submitted prior to the special
meeting. For limited partners who have not previously submitted a proxy and cash
election form and letter of transmittal, after consummation of the combination
transactions, the exchange agent will mail to each of these limited partners a
letter of transmittal and instructions explaining how to complete and submit the
letter. Limited partners will receive a certificate for the number of shares
that he is entitled to receive in accordance with the terms of the combination
transactions rounded to the nearest whole share. No fractional shares of Canaan
common stock will be issued.

Limited Partner Cash Election

          A limited partner in any partnership may elect to receive cash in lieu
of Canaan common stock equal to the Appraised Value of his interest in the
partnership regardless of whether the limited partner has voted in favor of the
combination transactions.

          In order to make an election to receive cash, limited partners must
properly complete the cash election portion of the proxy and cash election form
and letter of transmittal accompanying this document and return it to the
General Partner prior to the special meeting. If an election to receive cash is
properly indicated and the combination transactions are approved, the electing
limited partner will receive cash as provided above. If no specific election is
made, and the combination transactions are consummated, the limited partner will
receive Canaan common stock.

          Canaan will make payments to cash electing limited partners within
five days after the completion of the combination transactions.

          There is a limit on the amount of cash payable to limited partners
electing to receive cash of $15 million. If the amount of cash elections is more
than this limit, the combination transactions will not be consummated.

Revocation of Limited Partner Cash Election

          A limited partner may revoke his election at any time before the
special meeting. Any limited partner who attends a special meeting and wishes to
change his election may change his election at that time. Otherwise, a limited
partner must advise the General Partner of any change to his election in
writing, which writing must be received by the General Partner at its offices at
119 N. Robinson, Suite 600, Oklahoma City, Oklahoma 73102, prior to the time the
vote is taken at the special meeting.

Appraisal Rights


          The right of limited partners in any partnership to elect to receive
cash based on the Appraised Value of their interest in a partnership effectively
provides appraisal rights to all limited partners.


          Please see "The Combination Transaction - Cash Election" for
additional information.

NASDAQ Listing

          Canaan has applied to the NASDAQ National Market System for the
listing on a "when issued" basis of the shares of Canaan common stock to be
issued in the combination transactions under the proposed symbol "KNAN".

Interest of Certain Persons in the Transaction

          Leo E. Woodard and John K. Penton, directors and officers of Canaan,
are Additional General Partners of each of the partnerships and have each
personally guaranteed the partnerships' bank borrowings. Major shareholders of
Indian have on a limited basis personally guaranteed Indian bank borrowings. All
of these personal guarantees are expected to be released upon consummation of
the combination transactions. Upon the completion of the combination
transactions, Canaan
                                      -58-
<PAGE>


should have sufficient borrowing capacities to obtain credit without the need of
personal guarantees.

          Anthony Lasuzzo, a proposed executive officer of Canaan, is a
consultant to Indian and assists Indian in reserve evaluation and property sale
and drilling decisions.  Mr. Lasuzzo received a consulting fee of $75,000 paid
on March 1, 2000 for services from the period April 1, 1999 through March 1,
2001.  If the combination transactions are consummated, Mr. Lasuzzo is entitled
to a bonus of an additional $75,000 payable on consummation.  In addition,
pursuant to an agreement with Richard R. Dunning, a shareholder and director of
Indian, Mr. Lasuzzo has an option to purchase common stock of Indian from Mr.
Dunning immediately preceding consummation of the combination transactions
having a value equal to $150,000 based on Indian's Exchange Value for a price of
$1.00 per share, subject to the right of Mr. Dunning to deliver $150,000 cash in
lieu of shares of Indian common stock.

Resales of Canaan Common Stock

          Shares of Canaan common stock to be issued to limited partners in
connection with the combination transactions have been registered under the
Securities Act.   All shares of common stock received by them will be freely
tradeable after completion of the combination transactions.

          Likewise, all shares of Canaan common stock issued in the combination
transactions to shareholders of Indian will be registered under the Securities
Act.  The shareholders of Indian who are affiliates will be subject to
restrictions on sale pursuant to Rule 145 under the Securities Act. The shares
issued to shareholders of the General Partners and Canaan Securities will not be
registered under the Securities Act and will not be freely tradable unless
registered or exempt from registration.

Shareholder's Agreement

          Shareholders of Indian owning 81% of Indian's outstanding common stock
and the shareholders of Canaan and Canaan Securities will enter into a
shareholders' agreement among themselves and with Canaan which will go into
effect on closing of the combination transactions. This agreement grants Canaan
a right of first refusal on any sales of Canaan common stock by these
shareholders to the extent the sales by any shareholder would exceed 1% of the
outstanding Canaan common stock in any three month period.  In addition, these
shareholders have a pro rata right to participate in any purchases of shares by
any one of the shareholders that exceed 1% of the outstanding Canaan common
stock in any three month period.  The shareholders' agreement has a term of five
years.  All of the existing directors and executive officers of Canaan are
parties to the shareholders' agreement.  The shareholders who are parties to
this agreement will own 42%-60% of Canaan's outstanding common stock, depending
on the level of limited partner cash elections.

Accounting Treatment

          The combination transactions are expected to be accounted for as:


          .    A reorganization of entities under common control for the Coral
               Companies and the partnerships. As a result, the value of the
               assets and liabilities of the partnerships and the General
               Partners will be recorded at their historical cost.

          .    A purchase of Indian. As a result, the purchase price equal to
               the fair value of Indian's assets acquired and liabilities
               assumed will be allocated to the assets and liabilities of Indian
               as of the date of closing of the combination transactions.

          .    A purchase of Canaan Securities. As a result, the purchase price
               equal to the fair value of Canaan Securities' right to receive
               cash distributions and future fees for service based on the
               partnerships ongoing revenues from oil and gas properties will be
               allocated to the assets and liabilities of Canaan Securities
               based on their estimated values as of the date of closing of the
               combination transactions.

Expenses and Fees

          The costs and expenses incurred in connection with the combination
transactions are expected to be approximately $1,000,000, as summarized below:

          All of such fees and expenses will be borne by either Canaan or Indian
and will not be borne by the partnerships, unless the combination transactions
do not occur.  Indian has incurred and expensed its share of the combination
expenses totaling $150,000 related to the reserve report preparation fees.  If
the combination transactions do not occur, the remaining combination costs will
be borne by the Coral Group.  The partnerships will bear a share of the total
transaction costs based on their relative Exchange Values.  With respect to each
partnership, its share of the transaction costs will be allocated:

          .    To the General Partner in proportion to their percentage interest
     in the partnership operating costs, plus a percentage equal to the
     percentage of limited partners who abstain or vote against the Plan of
     Combination; and

          .    To the limited partners in proportion to the percentages of
     limited partners who voted to approve the plan of combination.

          The following table sets forth the allocation of the estimated
expenses within the Coral Group, the minimum amount of expenses allocable to the
General Partner and the Additional General Partners and the balance of expenses
to be allocated between the General Partner and the limited partners based on
the percentages of limited partners voting in favor of the combination
transactions.

          Funds for purposes of making cash payments to Placing Brokers and
limited partners electing to receive cash are expected to be borrowed by Canaan

               METHOD OF DETERMINING COMBINATION EXCHANGE VALUES
                              AND APPRAISED VALUES


General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities.  The following discussion describes all of the
factors considered in the determination of the Exchange Value.  The Exchange
Value takes into consideration the value of each of the Combining Entity's oil
and gas reserves determined as described below and the other assets and
liabilities of each Combining Entity as adjusted for other items for Canaan,
Indian and the 1996 and 1996-I partnerships.  The Exchange Value is used to
allocate the shares of Canaan common stock to each Combining Entity based on
relative Exchange Values.  This methodology is used based on the arm's length
negotiated agreement between Indian and Canaan and the General Partners in
connection with the negotiation of the Indian Acquisition Agreement and because
it is a consistent methodology for establishing the relative value of each
Combining Entity.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity.  Netherland Sewell
is a nationally recognized international petroleum consulting firm with
significant experience in petroleum engineering and geology.  Netherland Sewell
was selected by Canaan to perform the reserve studies being used for purposes of
the combination transactions based on its reputation in the industry and its
experience in evaluating reserves in the Mid-Continent basin where substantially
all of the reserves owned by the Combining Entities are located.  Netherland
Sewell & Associates is an international petroleum consulting firm with offices
in Dallas and Houston.  Netherland Sewell's staff includes petroleum engineers
and geological consultants.  Services they provide include reserve estimates,
fair value estimates, geological studies, expert witness testimony and
arbitration.  Netherland Sewell has previously performed isolated consulting
services for Canaan, for which it has received fees of less than $15,000 since
January 1, 1997.  There are no other relationships between Netherland Sewell and
any of the Combining Entities.  The fees paid to Netherland Sewell in connection
with the performance of its reserve analysis for the combination transactions
are not contingent in any respect on the approval or completion of the
combination transactions.

          Upon written request by a limited partner or his representative who
has been so designated in writing, a copy of the Netherland Sewell reserve
report shall be transmitted promptly, without charge, by the General Partner.
Request for copies of the reserve report should be directed to Canaan Energy
Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
                                      -62-
<PAGE>

Oklahoma 73102. A summary of the reserve reports of Netherland Sewell for each
Combining Entity is included in Appendix A.

          Neither Canaan nor the General Partner have had any contacts with any
other person concerning the possible preparation of reports by such persons
concerning the estimated reserves of the Combining Entities, evaluation of any
of the partnerships or their assets, the fairness of the combination
transactions or any other report with respect to the combination transactions
other than with Madison Energy Advisors who prepared appraisals of the
partnership oil and gas properties as described elsewhere in this document.


          Netherland Sewell estimated the reserves, future net revenues
therefrom and the present value of such future net revenues for each Combining
Entity as of September 30, 1999. We refer to the evaluation date of September
30, 1999 as the "Effective Date" and the present value of the estimated future
net revenues from estimated reserves as of the Effective Date as the "Reserve
Value" for each Combining Entity.  Netherland Sewell estimated each Combining
Entity's oil and gas reserves and applied the assumptions described below
regarding prices and costs for purposes of calculating future net revenue.
Future net revenue by year was calculated for each property.  The future net
revenue was then discounted at 10% for time using mid-year discounting.  The 10%
discount factor, as used by Netherland Sewell, is considered to be an industry
standard for valuing oil and gas properties and it is the standard promulgated
by the SEC for the valuation of oil and gas reserves reported on the balance
sheet.  However, this discount factor does not necessarily represent fair market
value.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers.  However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term"Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.  Properties with developed
reserves have less risk than properties with undeveloped reserves.  However,
there was no risk factor assigned to the type of reserves for purposes of
determining the Reserve Values.  No attempt was made to assign value to oil and
gas reserves categorized as probable or possible, because the General Partners
and Canaan believe such reserves are too speculative to value. Further no value
has been assigned for purposes of the combination transaction to any undeveloped
acreage or prospects owned by any Combining Entity which does not contain
Exchange Reserves.   Assigning a risk factor to reserves would cause a Combining
Entity with higher risk reserves to receive a lower Reserve Value.  Because none
of the Partnerships have significant reserves classified as undeveloped, or
probable or possible, Canaan does not expect the lack of "risk weighting" would
materially affect the relative Reserve Values of the partnerships.  However,
Indian's reserves are approximately 34% undeveloped and assigning a risk factor
to Indian's undeveloped reserves would likely lower Indian's relative Reserve
Value and its relative ownership of Canaan.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties.  The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions. See "Risk Factors and Material
Considerations" for additional information concerning risks associated with the
estimation of oil and gas reserves.

          The future net revenues from the properties for purposes of computing
the Reserve Value were based on the following assumptions which were provided to
Netherland Sewell by Canaan and the General Partners:

          .      Gas prices were established for each well separately based on a
                 ----------
                 12 month average of gas prices for the 12 months ending March
                 31, 2000. This average was constructed using the average of
                 composite spot wellhead prices as published by Natural Gas Week
                 for the 8 months ending November 30, 1999 and the forward
                 market prices for the 4 months ending March 31, 2000 based on
                 future prices quoted on the New York Mercantile Exchange
                 ("NYMEX") as of October 29, 1999 adjusted for the historical
                 differential between the New York Mercantile Exchange and
                 Natural Gas Week composite spot wellhead prices. The prices for
                 all wells averaged $2.52 per MMbtu before adjustment by well
                 for transportation fees, BTU content and regional price
                 differentials and were held constant for the life of the
                 properties. After adjustments by well for transportation fees,
                 BTU content and regional price differentials, the weighted
                 average gas price for all wells in the report was $2.43/Mcf.
                 The actual weighted average gas price for all wells for all
                 entities as of September 30, 1999 was $2.49/Mcf.

          .      Oil prices were established for each well separately based on
                 ----------
                 an 8 year average of West Texas Intermediate crude oil posted
                 prices for the 8 year period beginning in 1992 and ending on
                 December 31, 1999. This average was constructed using average
                 posted prices for West Texas Intermediate crude oil for 1992
                 through October 1999 and the forward market prices for November
                 and December of 1999 as quoted on the NYMEX as of October 29,
                 1999 adjusted for the differential between such forward market
                 prices and West Texas Intermediate posted prices. The prices
                 for all wells averaged $18.10 per barrel before adjustment by
                 well for gravity, transportation fees and regional price
                 differentials and were held constant for the life of the
                 properties. After adjustments by well for gravity,
                 transportation fees and regional price differentials, the
                 weighted average oil price for all wells in the report was
                 $19.68/Bbl. The actual weighted average oil price for all wells
                 for all entities as of September 30, 1999 was $22.81/Bbl.

                                      -64-

          .      Operating costs and production taxes were based on costs and
                 ------------------------------------
                 tax effect as of September 30, 1999 and were not escalated.

          .      A discount rate of 10% was used to discount future net
                 ---------------
                 revenues to present value at September 30, 1999.

          The Reserve Value will not be adjusted to take into account any actual
changes in oil and gas prices or costs subsequent to the Effective Date.  The
prices for gas used to compute the Reserve Value were based on average prices
for a one year period ending on March 31, 2000 in order to eliminate seasonal
variances, which included forward market prices quoted on October 29, 1999 for
periods subsequent to October 31, 1999.  The prices for oil were based on
average prices for the 8 years ending December 31, 1999.  In excess of 70% of
the reserves of each of the Combining Entities is gas and the Reserve Value is
more sensitive to changes in gas prices than oil prices.  Further, the Reserve
Value is being used to calculate the relative ownership of Canaan by each
Combining Entity and the Reserve Value of each entity is affected similarly by
changes in prices.

          Information concerning the ownership interest owned by each Combining
Entity was provided to Netherland Sewell by the Coral Group or Indian.  With
respect to undeveloped properties, the timing of planned development
expenditures was also provided by Canaan.

          The Reserve Value for each Combining Entity will be reduced by any
bank debt owed by each entity at the Effective Date.  No adjustments for
principal payments subsequent to the Effective Date are made because such
payments would be offset by a reduction in Reserve Value which would otherwise
be used to make such payments.

          The Exchange Value for each Combining Entity will also include an
amount attributable to its "working capital" as of the closing date of the
combination transactions. Working capital includes cash, short term investments,
oil and gas sales receivables and other accounts receivable and other current
assets less any current liabilities other than bank debt.  All of these assets
and liabilities were valued at book value, which in the opinion of Canaan and
the General Partners represents fair market value.

          The Reserve Value of the properties for each Combining Entity has been
established as of the Effective Date.  Interest paid or accrued on bank or any
other debt being assumed by Canaan subsequent to the Effective Date up to the
closing date will be a reduction to Exchange Value.  The Exchange Value for
limited partners, Additional General Partners, Canaan Securities and the Placing
Brokers will also be adjusted by reducing the Exchange Value for their share of
cash distributions after the Effective Date and before the closing date.  No
similar adjustments are being made for the other Combining Entities including
the General Partners because the revenues received by them will not be
distributed to owners or lenders and will be retained and used in their
respective businesses between the Effective Date and the closing date. It

                                      -65-
<PAGE>

is currently anticipated that substantially all net revenues of each partnership
received prior to the closing will be distributed to partners consistent with
past practice.

          In addition, an adjustment will be made at the closing for any gas
imbalances.  If a Combining Entity has produced and sold more than its share of
oil and gas from a property, its Exchange Value will be reduced by the estimated
value of the overproduction and if it has produced and sold less than its share
of oil and gas from a property, its Exchange Value will be increased by the
estimated value of the underproduction.  Canaan does not expect the amount of
this adjustment to have a material effect on the relative Exchange Values of all
Combining Entities.

          Additional adjustments will be made to the value of Canaan, Indian and
the 1996 and 1996-I partnerships as described below.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.


          .    For Canaan, an upward adjustment of $5.0 million for the value of
               its "operating rights" as described below.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for the Indian Contingent
               Production Payment as described below.

          The Exchange Values do not take into consideration any other assets or
liabilities of the Combining Entities. In the case of Canaan, Indian and Canaan
Securities, other assets would include furniture and equipment which Canaan and
Indian consider to be immaterial for purposes of establishing their relative
values. The partnerships do not own any furniture and equipment. In the case of
Indian, additional assets also include approximately $5.7 million of net
operating loss carryforwards as of March 31, 2000 and $1.6 million of statutory
depletion carryforwards, the use of which by Canaan in

                                      -66-
<PAGE>

future periods will be subject to limitations under Section 382 of the Internal
Revenue Code because the acquisition of Indian by Canaan will constitute a
change in control.

Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be  allocated among them in the ratio in which revenues and cash
distributions are shared.  This allocation method was selected because it fairly
represents the ongoing economic rights of the partners.  In each of the
partnerships except 1993-I and 1996-I, the General Partners' share of the net
revenues and cash distributions increases when "payout" occurs as to each
individual limited partner. Accordingly, in each of those partnerships in which
payout has not already occurred as to all limited partners as of the Effective
Date, the Reserve Value was allocated first among the partners in their
respective before payout sharing ratios until payout occurred and any remaining
Exchange Value was allocated in after payout sharing ratios.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues.  In each of these
partnerships, a portion of the Reserve Value, calculated based on gross
revenues, will be allocated to Canaan Securities representing rights to receive
such fee adjusted for any payments for such fee subsequent to the Effective Date
and before the closing date.  This allocation will be made prior to the
allocation of the remaining Reserve Value to the limited partners and the
General Partners.

          The Exchange Value for the General Partner and Additional General
Partners of the partnerships will be determined based on their share of the
Exchange Value for each of the partnerships as described above.

          The marketing arrangements entered into in connection with the sale of
interests in the partnerships provided for specified fees to be paid to Canaan
Securities and Placing Brokers.  Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships.  Accordingly, the Exchange Value allocated to the General Partner
in these partnerships will be reduced to take into consideration the amount of
the Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share.  The Placing Brokers will receive cash equal to 40% of their
Exchange Value and their share of Canaan common stock for the balance.

                                      -67-
<PAGE>

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Reserve Values will be made for cash distributions from production subsequent to
the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership does not
produce an "assumed return" of 100% of capital contributions plus 15% for the
limited partners as a group, the Exchange Value shall be first allocated to
limited partners until this assumed return is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages.  The
assumed return is based on the sum of historical cash distributions to limited
partners as a group through the closing date plus allocated Exchange Value as a
percentage of the original capital contributions of all limited partners.
Canaan and the General Partners believe that the 1996 partnership will be the
only partnership in which this priority allocation of Exchange Value may be
necessary.

Canaan Securities Exchange Value

          The Exchange Value for Canaan Securities will be determined in the
same manner as described above and will include an allocation to it attributable
to its rights to receive cash distributions from the partnerships and the
General Partners, less the Exchange Value allocated to Placing Brokers, as
described above under "Partnership Exchange Values and Allocation to Partners,
Canaan Securities and Placing Brokers".

Canaan Exchange Value

          The Exchange Value for Canaan will be determined based on its Reserve
Value, bank debt and working capital in the same manner as other entities as
described above.

          Canaan's Exchange Value will be further adjusted to take into account
its operating rights.  As of December 31, 1999, Canaan served as operator of 110
wells in which the partnerships own interests.  As such, Canaan receives monthly
operating fees which represent a source of additional income to Canaan.  For
purposes of calculation of Canaan's Exchange Value within the Coral Group, the
future cash flows attributable to these operating fees, based on existing
reimbursement rights without escalation, will be determined and the present
value thereof as of the Effective Date will be an additional component of its
Exchange Value.  The amount of this adjustment is approximately $5.0 million.
Canaan's net working capital adjustment will exclude any receivables
attributable to these fees.

          For purposes of determining relative Exchange Values between Indian
and the Coral Group as a whole, the operating rights value allocated to Canaan
is disregarded because the combination of the Coral Group results in the
elimination of a significant portion of Canaan's operating fees.  After the
combination transaction, Canaan will no longer receive operating fees from the
partnerships but will continue to receive fees from other unrelated owners.
Further, Canaan and Indian have agreed that neither of them will be allocated
value for operating rights for

                                      -68-
<PAGE>

purposes of determining the Exchange Value. This agreement is advantageous to
the Coral Group because Indian's operating fees are higher than Canaan's.

Indian Exchange Value

          The Exchange Value for Indian will be determined using the Reserve
Value, bank debt and working capital in the same manner as described above.

          In connection with the negotiation of the acquisition agreement
between Indian and the General Partners, Indian agreed that its Exchange Value
would be reduced by its production payment obligation to the 1996 and 1996-I
partnerships, in consideration of such partnerships advancing to Indian a total
of $6 million in exchange for a "Contingent Production Payment" from Indian to
the partnerships payable at the rate of $56,250 per month until paid in full.
The Contingent Production Payment is $9 million if the combination transactions
are consummated and $6 million if they are not.  Accordingly, Indian's Exchange
Value will be adjusted downward by the remaining amount of the Contingent
Production Payment obligation as of the Effective Date, $5,606,250, plus the
additional $3 million as a result of the combination transactions,  and the
Exchange Values for the 1996 and 1996-I partnerships will be adjusted upward by
the same amount.  As between the 1996 and 1996-I partnerships, the Contingent
Production Payment adjustment will be shared in the same percentages as their
original advances to Indian of 53% for the 1996 partnership and 47% for the
1996-I partnership.

Summary of Allocation of Exchange Values

          Summaries of the allocation of the estimated Exchange Values for the
partnerships, Canaan, Indian, the limited partners, the General Partners, the
Additional General Partners, Canaan Securities and Placing Brokers are contained
in the tables in the "Summary -Summary of Estimated Exchange Values".  More
detailed information concerning the calculation of the Exchange Value for each
individual partnership is contained in the individual partnership supplement for
each partnership.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership.  The Appraised Value was determined
based on an appraisal by Madison Energy Advisors of each partnership's oil and
gas properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values.  The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes  the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership.  The appraisal was obtained in
order to satisfy the

                                      -69-
<PAGE>

requirements of the National Association of Securities Dealers that limited
partners be offered the opportunity to receive cash equal to the Appraised Value
of their interest in the partnership.

          Madison Energy Advisors provides oil and gas reserve acquisition,
divestment and valuation advisory services to the upstream oil and gas industry,
including fair market value assessments of oil and gas properties.  Madison
Energy Advisors has offices in Houston, Texas and Denver, Colorado and has a
staff of professionals with significant experience in advising both buyers and
sellers of oil and gas properties.  Madison Energy Advisors was selected to
perform this appraisal because it is one of the recognized valuation experts in
the industry.  None of the Combining Entities has had any prior relationship
with Madison Energy Advisors.  The fees paid to Madison Energy Advisors are not
contingent in any respect on the approval or completion of the combination
transactions.

          A copy of the appraisal report of Madison Energy Advisors is included
as an exhibit to this document.  Upon written request by a limited partner or
his representative who has been so designated in writing, a copy of the report
shall be transmitted promptly, without charge, by the General Partner.  Request
for copies of the appraisal report should be directed to Canaan Energy
Corporation, 119 N. Robinson, Suite 600, Oklahoma City, Oklahoma, 73102.

          Madison Energy Advisors prepared the estimate of the appraised value
of the partnerships' oil and gas properties as of September 30, 1999, the
Effective Date for the calculation of the Exchange Value.  For purposes of
determining the value of the oil and gas properties, Madison Energy Advisors
reviewed the reserve estimates made by Netherland Sewell for its estimation of
the Reserve Value and concluded that the Netherland Sewell estimated reserve
quantities were reasonable and prepared in accordance with generally accepted
petroleum engineering and evaluation principles.

          For purposes of determining the appraised value of the oil and gas
properties, Madison Energy Advisors used the following criteria:

          .    Oil and gas prices.  For purposes of determining the estimated
               ------------------
               future net revenues from the Exchange Reserves, Madison Energy
               Advisors applied more current pricing based on its April 1, 2000
               quarterly pricing poll for active middle market buyers.  These
               prices reflect representative prices used in connection with the
               purchase and sale of oil and gas properties. Before adjustment
               for transportation fees, BTU content and gravity and regional
               price differentials, the prices used by Madison Energy Advisors
               were $2.74/Mcf for gas and $25.97/Bbl for crude oil.  These
               prices were adjusted as follows:

                Thereafter   1% per year increase  2.44% per year increase


          .    Operating costs and production taxes were based on costs and tax
               rates in effect as of the Effective Date and costs were escalated
               at the rate of 1.75% per year.

          .    A discount rate of 20% was used to discount future net revenues
               to present value as of the Effective Date. Madison Energy
               Advisors believes the 20% discount rate is appropriate due to the
               classification of the partnership properties as "lower tier".
               Lower tier properties are those which are small non-operated
               interests with no field or basin concentration or control.

          .    Risk factors were applied to the present value of the estimated
               future net revenues from the oil and gas reserves to reduce to
               the percentage of estimated present value set forth below:

                    .  Developed non-producing - 65%

                    .  Undeveloped - 35%

          .    The appraised value of the properties also reflects a 5%
               reduction for estimated commissions and transaction expenses
               payable in connection with the sale of the properties and
               winding-up of the partnership affairs.

          Madison Energy Advisors prepared its appraisal of the partnership oil
and gas properties on May 3, 2000, using its prior assumptions for oil and gas
as of April 1, 2000.  It is not anticipated that the appraisal of Madison Energy
Advisors will be updated.  Canaan and the General Partners are not aware of any
conditions that have changed since the date of the appraisals that would have
caused material change in the value of the appraised value of the partnerships'
oil and gas properties as estimated by Madison Energy Advisors.

          The following table sets forth the appraised value of each of the
partnerships' oil and gas properties in comparison to the Reserve Value used for
purposes of calculating the Exchange Value, both as of September 30, 1999.  As
noted elsewhere in this document, the

                                      -71-
<PAGE>

Reserve Value is used solely for purposes of calculating the Exchange Value and
does not represent the fair market value of the partnerships' oil and gas
properties. The appraised value of the properties represents Madison Energy
Advisor's opinion of the price at which they could be sold. These values are
different primarily due to the differing assumptions with respect to oil and gas
prices, costs, discount rates and risk factors.

</TABLE>

          After the appraised value of the partnerships' oil and gas properties
was established by Madison Energy Advisors for each partnership as of the
Effective Date, such property values were reduced for actual and estimated net
revenues from the properties for the period from the Effective Date to the
closing date to arrive at the estimated appraised value as of such date.   This
adjustment is made so that the appraised value of the properties is computed as
of a date consistent with the date of calculation of the Exchange Value.

          Canaan and the General Partners then computed the estimated value of
each limited partner's interest in the partnership based on the assumption that
the partnership's oil and gas properties were sold for the resulting value and
the gain on sale was allocated to the partners in accordance with the provisions
of the applicable partnership agreement and that each partnership was
liquidated, with the proceeds of liquidation, including estimated working
capital at the closing date and after payment of any partnership debt as of the
closing date, being distributed as required by the partnership agreement.  The
resulting amount is referred to as the "Appraised Value".

          The economic terms of each of the partnerships generally provided for
the limited partners to provide all of the capital of the partnership and to
bear a greater percentage of the share of costs associated with each
partnership's initial acquisition and development of properties.  As a result,
the limited partners in each partnership have capital account balances which are
higher, on a relative capital account basis, than their interest in revenues of
the partnership.  The partnership agreement for each partnership requires that
the capital accounts be recognized or "balanced" in connection with any
liquidation of the partnership.  These balancing provisions result in the
limited

                                      -72-
<PAGE>

partners receiving a priority allocation of the liquidation proceeds as a result
of their relatively higher capital account balances. The effect of this priority
allocation is that the limited partners receive a greater share of liquidation
proceeds than what limited partners would have received from the production of
the oil and gas properties owned by each partnership had the properties been
produced to depletion. Any liquidation of a partnership would therefore result
in a relative higher proportion of liquidation value being allocated to the
limited partners than is being done in connection with the combination
transactions in which the allocation of Exchange Value between the limited
partners and the general partners is being done based on revenue sharing
percentages. However, Canaan and the General Partners believe that the
discounted prices expected to be realized in a sale of properties in a
liquidation based on the appraisal of Madison Energy Advisors offsets the
potential incremental liquidation value allocated to limited partners.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to equal such amount. Canaan and the General Partners believe
that the 1996 and 1996-I partnerships will be the only partnerships in which the
Appraised Value plus historical cash distributions may not meet the 100% of
original investment amounts.

          The Appraised Value for each partnership ranges from 54% to 83% of the
Exchange Values.  The following table sets forth for each partnership the
historical and estimated cash distributions, the estimated Appraised Value plus
cash distributions and Appraised Value as a percent of original investment for
the limited partners as a group and for each limited partner per $1,000 of
investment.  All of these tables assume closing of the combination transactions
on July 31, 2000, and use actual property net revenues through  March 31, 2000,
and estimated revenues and expenses from the Netherland Sewell reserve reports
for purposes of calculating estimated property net revenues thereafter.
Variances in net revenues or a change in the closing date will result in a
change in the Appraised Value for any entity affected.  See "Recommendation of
the General Partners and Fairness of the Combination Transactions -Comparison of
the Alternatives" for a discussion of the variances between the partnerships in
the measure of Appraised Value in relation to Exchange Value.

                  RECOMMENDATION OF THE GENERAL PARTNERS AND
                   FAIRNESS OF THE COMBINATION TRANSACTIONS

General

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

                                      -74-
<PAGE>

          See "Background and Reasons For the Combination Transactions", for
information concerning factors Canaan and the General Partners considered in
recommending the combination transaction in addition to those discussed in this
section.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions receiving Canaan common stock
is the determination of the Exchange Values.  As noted elsewhere in this
document, the Exchange Values are based primarily on the Reserve Value based on
Netherland Sewell's independent valuations.  By using Reserve Values calculated
in a consistent manner by a single engineering firm based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions. Further, Canaan and the General Partners believe the following
facts support the fairness of the transaction to the limited partners:

          .    Owners of all of the Combining Entities in the combination
               transactions are receiving the same form of consideration,
               consisting of common stock of Canaan, except limited partners who
               elect to receive cash, and the relative number of shares to be
               received by the owners of each entity is being calculated on a
               consistent basis for each Combining Entity.

          .    Canaan believes that shares of publicly held oil and gas
               companies generally trade at values greater than their cash
               liquidation values, affording limited partners potentially
               greater value than represented by the cash value of the
               partnership's oil and gas properties, either in immediate
               liquidation or in continuing the partnership. Canaan believes
               publicly held oil and gas companies generally trade at premiums
               to their potential cash liquidation values due to value
               attributable to going concern and potential growth and due to the
               fact that public company stock valuations do not reflect
               discounts for nonproducing reserves typically applied in cash
               transactions.

          .    All of the partnerships had similar investment objectives and all
               own similar properties, principally non-operating interests in
               proved developed producing gas properties located primarily in
               Oklahoma in the Mid-Continent basin. Therefore, Canaan and the
               General Partners do not believe that there are material
               differences in the assets of the partnerships that would cause
               their values to vary based on quality of reserves or differences
               in commodity prices for gas or oil.

          .    The use of Reserve Value to evaluate the Combining Entities is a
               commonly used method in valuing oil and gas properties.

                                      -75-
<PAGE>

          .    As between the General Partners and the limited partners, the
               allocation of Exchange Value in each partnership is based on the
               profit sharing percentages provided in the partnership agreements
               and there is no additional consideration being allocated to the
               General Partners or Canaan which is not currently being received.

          .    The actual market value of the Canaan common stock received by
               limited partners may be more or less than their Exchange Value,
               but the owners of Canaan, the General Partners and Indian will
               all be similarly affected by any differences.

          .    The methodology for determining Exchange Values as between Indian
               and the Coral Group was agreed to by the owners of Indian in an
               arms length negotiated transaction between Indian and Canaan.

          .    The combination transactions will not be approved unless the
               holders of a majority of the interests in each partnership
               approve the combination transactions. Further, all partnerships
               are required to be included in the combination transactions for
               it to be consummated so it is not possible that any one
               partnership will be excluded.

          .    A limited partner of a partnership may elect to receive cash in
               lieu of Canaan common stock in an amount equal to the Appraised
               Value of such limited partner's interest. This cash election
               provides the opportunity for limited partners who are unwilling
               to take market risks with respect to Canaan common stock the
               opportunity to receive cash in an amount which Canaan and the
               General Partners believe approximates fair value based on an
               appraisal of the partnership oil and gas properties performed by
               an independent appraiser.

          .    In each partnership, the General Partner is entitled to receive a
               reimbursement for a portion of its overhead expenses, including
               office rent and salaries for clerical staff and appropriate
               production supervisory personnel and any other overhead expenses
               which the General Partner deems reasonable. The amount of the
               overhead reimbursement is limited to 5% of the amount of
               distributable cash. This overhead reimbursement amount is not
               being taken into consideration in the calculation of the General
               Partner's share of the Exchange Value. However, if the
               partnerships continued to operate, the General Partner would
               continue to be entitled to such reimbursement. Thus, the present
               value of future cash distributable to limited partners, if the
               partnerships were continued, based on the same projections of
               future net revenues used to calculate the Exchange Values would
               be less than the Exchange Value allocated to limited partners.


                                      -76-

          The Exchange Value does not represent the absolute fair market value
of a partnership's oil and gas properties or the interest of a limited partner.
No firm offer has been made by any person during the preceding 18 months
regarding the merger or consolidation of any of the partnerships, the sale or
transfer of all or any substantial part of the assets of any partnership or
securities of any partnership which would enable the holder thereof to exercise
control over a partnership.

          For purposes of determining the relative Exchange Value of Canaan
within the Coral Group, Canaan's Exchange Value includes, in addition to the
valuation of its oil and gas properties, a value attributable to its operating
rights.  The allocation of value to Canaan for its operating rights recognizes
that Canaan is entitled to receive fees for these activities from the
partnerships and other nonoperating owners which Canaan would be entitled to
continue to receive if the combination transactions did not occur.  This
allocation of Exchange Value to Canaan is intended to recognize the economic
benefits that Canaan currently receives in connection with the partnerships and
is not intended to allocate additional new economic benefits to Canaan.

          For purposes of determining relative Exchange Values between Indian
and the Coral Group as a whole, the operating rights value allocated to Canaan
is disregarded because the combination of the Coral Group essentially results in
the elimination of a significant portion of Canaan's operating fees.  After the
combination transaction, Canaan will no longer receive operating fees from the
partnerships but will continue to receive fees from other unrelated owners.
Further, Canaan and Indian have agreed that neither of them will be allocated
value for operating rights for purposes of determining the Exchange Value.  This
agreement is advantageous to the Coral Group because Indian's operating fees are
higher than Canaan's.

          The Reserve Value for each of the Combining Entities will not be
adjusted for any changes in oil and gas prices subsequent to the Effective Date.
The gas prices used to calculate the Reserve Value were based on an average of
12 months of prices for a period ending on March 31, 2000 using 8 months of
historical actual prices and 4 months of forward market prices in effect at the
Effective Date.  The oil prices were based on an 8 year average price ending
December 31, 1999.  The Reserve Value thus takes into effect seasonal
fluctuations in gas prices and historical volatility of oil prices.  Further,
more than 69% of the Reserve Value of each Combining Entity is gas and the
Reserve Values are, therefore, more sensitive to gas price changes than oil
price changes.  Canaan and the General Partners believe that the Reserve Value
of all of the Combining Entities would be affected similarly by changes in
prices.  Canaan and the General Partners have also disregarded short term hedges
of oil and gas production by the partnerships and Indian in the calculation of
Reserve Values because these hedges expire on or before the end of 2000 and are
not expected to have a material effect on production revenues over the life of
the properties.  However, because all of the partnerships except the 1995
Partnership and Indian have bank indebtedness, the Exchange Value for such
entities will be more than proportionately benefited by increases in oil and gas
prices and more than proportionately disadvantaged by decreases in oil and gas
prices.  Because Indian has more debt relative to Reserve Value than any other
Combining Entity, its

                                      -77-
<PAGE>

Exchange Value is more dramatically affected by changes in prices. However,
because of the numerous uncertainties associated with the calculation of the
Reserve Value in addition to the price assumptions, Canaan and the General
Partners do not believe that a recalculation of the Reserve Value based on
temporary changes in product prices is appropriate.

 Consideration of Alternatives

          In evaluating the fairness of the transaction, Canaan and the General
Partners also considered the possible value of the consideration to be received
in the combination transactions compared to the values that Canaan and the
General Partners estimated would be received by the limited partners if the
partnerships were continued or liquidated.


          Continuation. Continuation of the partnerships, while avoiding the
risks associated with the combination transactions and the discontinuance of
cash distributions, would result in declining operating results and distribution
rates for each of the partnership because:

          .    Reserves will be depleted in the ordinary course from ongoing
               production.

          .    Lease operating costs will remain the same or increase and
               potentially become a greater percentage of oil and gas revenues
               as production declines regardless of the operating results of the
               partnerships assets.

          .    The partnerships would have to incur the costs of plugging and
               abandoning partnership wells when they become uneconomic or any
               future sale of the partnerships' wells would be at a price which
               would reflect the anticipated costs of such plugging and
               abandonment expenses. Canaan will bear these expenses if the
               combination transactions are consummated but may be able to
               achieve some expense savings by being a larger organization.


          .    The partnerships do not have additional sources of capital to
               support growth or additional development activity. The
               partnerships may not have the cash nor the ability to borrow
               funds necessary to develop their non-producing reserves. This may
               result in reduction or temporary suspension of cash distributions
               in order to participate in proposals to place these non-producing
               reserves on production, or the partnerships may be forced to
               forego participation in these proposals.

          .    All of the partnerships except the 1995 partnership have incurred
               significant debt to engage in additional development. This debt
               has not been amortized in any material respect. Principal
               payments on partnership debt will adversely affect cash
               distributions and require limited partners to report taxable
               income on principal repayments.

                                      -78-
<PAGE>

          .    The partnerships will continue to incur general and
               administrative reimbursement costs in favor of the General
               Partner.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was continued after the estimated closing date of
July 31, 2000.  This value is referred to as the "Continuation Value".  Such
continuation analysis is based on the following assumptions:

          .    The estimated future net revenues from the sale of oil and gas
               after July 31, 2000 are based on the same prices and costs that
               are used to estimate the Reserve Value for purposes of the
               Exchange Value.

          .    The partnerships will continue to incur general and
               administrative expenses in favor of the General Partner as
               provided in the applicable partnership agreement in the amount of
               5% of the amount of distributable cash.

          .    Any partnership with bank debt is assumed to amortize such debt
               on a 36 month level amortization basis, assuming an interest rate
               of 9%, beginning July 31, 2000.

          .    The estimated future net cash flows were then discounted at a
               discount rate of 10% to arrive at the estimated Continuation
               Value.

          The following table sets forth by partnership the estimated
Continuation Value for all limited partners as a group and per $1,000 of
investment.

          The actual amount that limited partners would receive if the
partnerships continue their respective operations will depend on production
levels and future oil and gas prices, which cannot be predicted with certainty.
To the extent that future prices for those commodities are materially higher or
lower than the pricing assumptions made to estimate Continuation Value, those
fluctuations would likely have a similar effect on the operating of wells,
distribution rates and Continuation Value.

          Liquidation.  A sale of the partnership assets and liquidation of the
partnership would result in immediate cash distributions to the limited partners
and avoid the market risks associated with the ownership of Canaan common stock.
Canaan and the General Partners believe that the material risks relating to a
liquidation of any one or more of the partnerships outweigh the potential
benefits thereof.  The principal benefits to limited partners of any partnership
of liquidation as opposed to continuation or participation in the combination
transactions would be the immediate realization of the cash proceeds of the sale
of such properties and the avoidance of the risks and uncertainties associated
with realizing the value of such properties over time or ownership of Canaan
common stock.  The material risks of such liquidation would be that the prices
the partnership would receive for its properties upon liquidation from third
party purchasers would be materially less than the value of the future cash
flows from such property discounted

                                      -80-
<PAGE>


solely for the time value of money and less than the market value of Canaan
common stock received.

          Canaan and the General Partners believe the liquidation of the
partnerships would be less beneficial to limited partners because:

          .    The prices paid by purchasers of partnership properties in
               liquidation would likely include a substantial discount for the
               risks and uncertainties of future cash flows which are not
               included in the calculation of Reserve Values. Purchasers
               typically apply risk discounts to reserve values for reserves
               which are not proved developed producing reserves.

          .    In addition, Canaan and the General Partners believe that
               additional discounts would be applied in the valuation of
               partnership oil and gas properties related to:

               .    The relative large number of individual properties owned by
                    each partnership and the relatively small working and
                    revenue interests owned by the partnerships in each of its
                    properties;

               .    The fact that all partnership's properties are non-operated
                    and many third party purchasers prefer to operate
                    properties;

               .    The additional costs incurred during the extended amount of
                    time it would take to orderly dispose of a large number of
                    properties including the costs of brokers and agents
                    employed to facilitate the sale of properties;

               .    The complexity involved administratively to transfer a large
                    number of properties from several entities to a third party
                    purchaser.

          .    Liquidation would result in a taxable transaction to all limited
               partners, many of whom may not desire such consequences. The
               ability of limited partners to receive shares of Canaan common
               stock in a tax-free transaction gives them the benefit of an
               investment in a larger more diversified property base, together
               with the ability to liquidate their investment in whole or in
               part in the market by selling their common stock if they desire
               to do so and to determine the timing of any tax consequences. In
               addition, a cash liquidation would result in a material portion
               of the liquidation proceeds being taxed as ordinary income as a
               result of the requirement to recapture cumulative tax deductions
               for depletion, depreciation and intangible drilling costs. A sale
               of Canaan common stock will be potentially taxable at lower long-
               term capital gain rates.

          .    Canaan and the General Partners believe that shares of publicly
               held oil and gas companies are generally traded in the market at
               prices in excess of net liquidation value based on estimated oil
               and gas property values. As a result, limited partners are
               expected to have more value in Canaan common stock than if the
               underlying assets were sold.

          .    Liquidation would deprive limited partners of the ability to
               benefit from future increases in prices for oil and gas which
               Canaan and the General Partners believe would have an indirect
               beneficial effect on the price of Canaan common stock.

          .    Liquidation would require additional administrative, legal and
               accounting costs for winding up of the partnerships.

          In order to offer limited partners who do not desire to receive Canaan
common stock an alternative, Canaan and the General Partners have structured the
transaction to permit limited partners to receive cash equal to the Appraised
Value of their partnership interests which they believe, based on the
independent opinion of Madison Energy Advisors, approximates the liquidation
value of their interests.

          The economic terms of each of the partnerships generally provided for
the limited partners to provide all of the capital of the partnership and to
bear a greater percentage of the share of costs associated with each
partnership's initial acquisition and development of properties.  As a result,
the limited partners in each partnership have capital account balances which are
higher, on a relative capital account basis, than their interest in revenues of
the partnership.  The partnership agreements for each partnership require that
the capital accounts be recognized or "balanced" in connection with any
liquidation of a partnership.  These balancing provisions result in the limited
partners receiving a priority allocation of the liquidation proceeds as a result
of their relatively higher capital account balances.  The effect of this
priority allocation is that the limited partners receive a greater share of
liquidation proceeds than what limited partners would have received from the
production of the oil and gas properties owned by each partnership had the
properties been produced to depletion.  Any liquidation of a partnership would
therefore result in a relative higher proportion of value being allocated to the
limited partners than is being done in connection with the combination
transactions in which the allocation between the limited partners and the
general partners is being done based on revenue sharing percentages.  However,
Canaan and the General Partners believe that the discounted prices expected to
be realized in a sale of properties in a liquidation offsets any potential
incremental liquidation value allocated to limited partners.

          Canaan and the General Partners have computed a liquidation analysis
of each of the partnerships which for each partnership is equal to the Appraised
Value based on the appraisal of the partnership's oil and gas properties
conducted by Madison Energy Advisors. The appraisal by Madison supported the
belief of Canaan and the General Partners that substantial discounts are applied
in calculating the market value of the partnership's properties due to the
nature of the

                                      -82-
<PAGE>


properties. A description of the methodology for computing the Appraised Value
is set forth under "Method of Determining Combination Exchange Values -
Determination of Appraised Value".

</TABLE>

          Variances in Appraised Value in relation to Exchange Value for the
limited partners of each of the partnerships as a group result primarily from
the following factors:

     .    The appraisal value of the oil and gas properties is substantially
          less than the Reserve Value used to calculate the Exchange Value.
          While the property appraisal values were based on higher future prices
          than used for the Reserve Value, the Appraised Value is based on a 20%
          discount rate and applies risk factors to non-producing reserve
          categories, whereas the Reserve Value is based on a 10% discount rate
          and no risk factors.

     .    The level of debt in each partnership in relation to the appraisal
          value of the properties varies. Partnerships with higher debt levels
          relative to property values, such as the 1990 and 1991 partnerships,
          have relatively lower Appraised Value in relation to reserve value.



                                      -83-
<PAGE>


          .    The Appraised Values of the 1996 and 1996-I partnerships are
               adversely affected by the elimination of the $3 million Indian
               Contingent Production Payment adjustment, which increases the
               Exchange Values of such partnerships, but is not applicable in a
               liquidation assumption for the Appraised Value.

           .   The 1993 and 1995 partnerships have relatively high Appraised
               Values in relation to Exchange Values for the limited partners of
               each partnership as a group. This is primarily attributable to
               the before-payout, priority allocation of liquidation proceeds to
               the limited partners, and, in the case of the 1995 partnership,
               the absence of significant debt.

          .    The 1990, 1991 and 1992 partnerships' Appraised Values for
               limited partners are relatively lower in each case because, in
               these partnerships, payout has already occurred or is near
               occurring resulting in a greater percentage of liquidation
               proceeds being allocated to the General Partners.

          As noted elsewhere, the Exchange Value does not necessarily represent
the fair value of the partnerships or any partnership's net assets, and is being
used solely for purposes of determining the relative ownership of Canaan by each
of the entities involved. Accordingly, there is no assurance that the value of
the common stock received by a limited partner will be equal to the Exchange
Value allocable to such limited partner. Notwithstanding the foregoing, Canaan
and the General Partners believe that the combination transactions are fair
because:

          .    Canaan and the General Partners believe that shares of publicly
               held oil and gas companies generally trade at values greater than
               their underlying reserve cash liquidation values, affording
               limited partners potentially greater value than represented by a
               partnership's liquidation or continuation value; and

          .    The cash election affords limited partners desiring to receive
               liquidation value the opportunity to do so in lieu of accepting
               Canaan common stock.

 Fiduciary Duties of General Partners

          General. The General Partners' fiduciary duties to the limited
partners include legal responsibilities of loyalty, care and good faith. The
General Partners may not profit by any conduct or transaction in contravention
of its fiduciary obligations to limited partners. Rights of action by or on
behalf of the limited partners for any breach of these duties are provided under
Oklahoma partnership law. If a limited partner believes that the proposed Plan
of Combination or the consummation thereof would constitute a breach of his
General Partner's fiduciary duties, the limited partner could institute legal
action against the General Partner to enjoin the consummation transactions or to
recover damages resulting from the consummation of the transactions. In

                                     -84-
<PAGE>


appropriate circumstances, a limited partner may institute a class action
against his General Partner on behalf of himself and the other similarly
situated limited partners or a derivative action against his General Partner on
behalf of the partnership to recover damages for a breach of his General
Partner's fiduciary duties. A limited partner who votes to approve the
combination transactions may not be able to assert claims for breaches of
fiduciary duty by the General Partners in the absence of a claim that all facts
necessary for the limited partner to make an informed decision were not properly
disclosed. This is a developing area of the law, and limited partners who have
questions concerning the General Partners' duties should consult with their own
legal counsel.

          Operating Rights. As of March 31, 2000, Canaan served as operator of
107 of the wells in which the partnerships own non-operating working interests
and received operating fees for such services from the partnerships. This
arrangement is permitted by the terms of the applicable partnership agreements.
While Canaan is not the General Partner of the partnerships, it is owned by the
same persons who own the General Partners and its principal business activity is
providing services to the General Partners. As a result of this relationship, it
is possible that Canaan could be considered to be a fiduciary to the limited
partners and owe to them the same duties of loyalty, care and good faith as owed
by the General Partners. The limited partners may therefore have the same rights
with respect to Canaan as they have with respect to the General Partners.
Further, the value of the partnership oil and gas properties might be enhanced
if the partnerships had the right to operate the properties rather than Canaan
or if Canaan would relinquish its operating rights in connection with a sale of
properties by a partnership. In such event, the liquidation value of the
partnership properties may be greater than the value of the properties without
the right to operate. However, the partnerships do not have the administrative
and other staff necessary to serve as operator of wells.

          Limitations on Limited Partners' Remedies. The partnership agreements
for the partnerships provide that the General Partner and its affiliates are not
liable to the partnership or any partner for any losses arising out of any
action or inaction of the general partners if the general partners, in good
faith, determine that such course of conduct was in the best interest of the
partnership and such course of conduct did not constitute negligence or
misconduct of the general partners. In addition, the partnership agreements
provide that the partnerships will indemnify the general partners for any
losses, judgments and amounts paid in settlement of any claims sustained by them
in connection with the partnership provided that they were not the result of
negligence or misconduct on the part of the general partners. The partnership
agreements further provide for the advancement of legal expenses and other costs
incurred by the general partner in connection with any proceeding arising by
reason of the fact that it is or was a general partner of the partnership, but
such advancement of legal expenses and other costs is not available to a general
partner when an action is initiated by a limited partner.

 Access to Investor List

          Under Oklahoma law and the partnership agreement of each partnership,
a limited partner may obtain a list of limited partners in his partnership by
making a written request to the General Partners at 119 N. Robinson, Suite 600,
Oklahoma City, Oklahoma 73102.  Limited partners also have the right under the
partnership agreements to inspect the books and records of his partnership at
reasonable times and upon reasonable notice.

 Conflicts of Interest

          Canaan and the General Partners have conflicts of interest with the
limited partners with respect to the combination transactions arising from,
among other things:

          .    Canaan and the General Partners determined the structure of the
               proposed combination transactions and the Exchange Values without
               any independent third party representing the limited partners of
               any partnership. As a result, the determination of the Exchange
               Values and the relative ownership of Canaan by limited partners
               may not reflect the allocation of relative value that would
               result if the combination transactions were negotiated with an
               unaffiliated third party in an arms length transaction.

          .    Officers and directors of Canaan and the General Partners will
               continue to serve as officers and directors of Canaan. They may
               receive compensation and other benefits associated with this
               employment as determined by the board of directors and which may
               be higher than their current compensation arrangements.

          .    Legal counsel engaged to assist with the preparation of the
               documentation for the combination transactions, including this
               document was engaged by Canaan and did not serve, or purport to
               serve, as legal counsel for the limited partners.

          .    For purposes of the allocation of the Exchange Value within the
               Coral Group, Canaan is being allocated additional Exchange Value
               attributable to its rights to operate partnership properties.
               Approximately 62% of Canaan's ongoing operating fees come from
               the partnerships. For purposes of determining the relative value
               of the Coral Group as a whole and Indian, these operating fees
               are disregarded because after giving effect to the combination
               transactions, this intercompany item as between Canaan and the
               partnerships is eliminated. Canaan and the General Partner
               believe this allocation of value is consistent with industry
               practices generally, but it has not been established on an arms
               length basis and may have the effect of allocating to Canaan a
               greater share of the total Exchange Value.

                                     -86-
<PAGE>

 No Independent Representative

          No independent representative of the limited partners was engaged for
purposes of negotiating the terms of the combination transactions, nor was a
fairness opinion obtained from an unaffiliated third party. The absence of these
protections was considered, but was not judged to be significant by Canaan and
the General Partners, in determining the fairness of the proposed combination
transaction to the limited partners. Because the Exchange Values used in
determining the shares of Canaan common stock to be received by the limited
partners in the partnerships in exchange for their interest were primarily based
on the Reserve Values determined by Netherland Sewell with immaterial adjustment
based on such variables as cash, short term investments, liabilities and cash
flow, Canaan and the General Partners determined that the likelihood that such
an unaffiliated representative of the limited partners or a fairness opinion
would add value to the process of structuring the combination transactions was
minimal and outweighed the costs of retaining such a representative or fairness
opinion. As a result, the Exchange Values and other terms of the combination
transactions may not be as favorable as the terms that might have been obtained
had an independent representative been retained or a fairness opinion requested.


                FAILURE TO APPROVE THE COMBINATION TRANSACTIONS

          If one of the partnerships fails to approve the combination
transactions, the combination transactions will not be consummated for any of
the partnerships. If the combination transactions are not approved, each
partnership will continue in its business as previously conducted. However, it
is possible that a new transaction might be proposed by Canaan or the General
Partners, but no other terms have been discussed or considered by them. In
addition, Canaan and the General Partners may also explore other alternatives,
such as sale of the Coral Group to a third party, but there is no assurance that
Canaan or the General Partners could find a third party interested in purchasing
the assets or that the terms and conditions of any such purchase and sale
agreement would be as favorable as the terms offered pursuant to the combination
transactions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships. Limited partners
in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interests of limited partners voting in
favor of the combination transactions. Please see "The Combination Transactions-
Expenses and Fees" for a discussion of the sharing of transaction costs.

          If the combination transactions are not consummated, the amount of the
remaining balance of the Contingent Production Payment owing from Indian to the
1996 and 1996-I partnerships will be reduced by $3 million. This will result in
no gain or return on the amount of these partnerships' investments in the
Contingent Production Payment. The payment of this

                                     -87-
<PAGE>

obligation is subordinate to Indian's obligations to its bank lenders and
depending on the amount of the liquidation proceeds, the Contingent Production
Payment may not be paid in full. These partnerships would also be entitled to
share a portion of the 50% of the remaining proceeds of liquidation otherwise
distributable to Indian shareholders, which is uncertain. The amount invested in
the Contingent Production Payment represented 33% of the initial capital of the
1996 partnership and 43% of the initial capital of the 1996-I partnership. Thus,
the failure to approve the combination transactions would adversely affect the
returns to the limited partners in these partnerships unless the Contingent
Production Payment repayment proceeds are successfully reinvested.


                      SPECIAL MEETING OF THE PARTNERSHIPS

 General

          A combined special meeting of the partnerships is being called by the
General Partners for limited partners to consider and vote to approve or
disapprove of the Plan of Combination relating to the combination transactions
and to transact such other business as may be properly presented at the special
meeting or any adjournments or postponements thereof.

          The combined special meeting will be held on ___________________, at
____________ p.m. at __________________________________________, Oklahoma City,
Oklahoma ________.

 Voting Rights

          Each limited partner appearing on the records of each of the
partnerships as of _________________, 2000 is entitled to notice of the special
meeting and is entitled to vote his partnership interests at the meeting. Each
partnership is voting separately on the Plan of Combination. Accordingly, not
all of the partnerships may approve the Plan of Combination. Limited partners in
each partnership may vote "FOR" or "AGAINST" their respective partnership
participating in the Plan of Combination.

          The General Partners appointed UMB Bank, N.A., Kansas City, Kansas to
receive and tabulate all votes and dissents of limited partners in each
partnership. UMB Bank has no other relationship with the Combining Entities
other than being appointed to serve as exchange agent and transfer agent for
Canaan's common stock. UMB Bank will make the tabulation available to the
General Partners and any limited partner upon request at any time during and
after the voting occurs. Requests should be addressed to UMB Bank, N.A., P. O.
Box 410064, Kansas City, Kansas 64141-0064, Attention: Nancy Hoffman.

Proxy and Cash Election Form and Letter of Transmittal

          A sample of the form of proxy and cash election form and letter of
transmittal is attached to this document. The actual Voting Form to be used to
register your vote on the plan of combination involving your partnership is the
separate green sheet of paper included with this document. Please Use the Green
Proxy and Cash Election Form and Letter of Transmittal to Cast Your Vote on the
Plan of Combination.


Approval/Revocation of Proxy and Cash Election Form

          If a Voting Form is properly signed and is not revoked by a limited
partner, the partnership interest it represents will be voted in accordance with
the instructions of the limited partner. If no specific instructions are given,
the partnership interest will be voted FOR the Plan of Combination involving
your partnership. A limited partner may revoke his vote at any time before it is
voted at the special meeting. Any limited partner who attends the special
meeting and wishes to vote in person may revoke his vote at that time.
Otherwise, a limited partner must advise the General Partner of revocation of
his vote in writing, which revocation must be received by the General Partner at
119 N. Robinson, Suite 600, Oklahoma City, Oklahoma 73102 prior to the time the
vote is taken.

          The Voting Form also includes methods by which a limited partnership
in each partnership can make an election to receive cash as described under "The
Combination Transactions - Cash Election".

 Solicitation

          The solicitations of proxies are being made by Canaan, the General
Partners of the partnerships and Canaan Securities. The proxies will be
solicited in person, through the mail and over the telephone. No solicitation
will occur over the Internet and no special compensation will be paid for such
solicitations. The costs of the preparation of this document and of the
solicitation of proxies and such costs for each partnership will be borne as
described under "The Combination Transactions - Expenses and Fees".

 Voting Requirements

          Approval of the Plan of Combination by each partnership requires the
approval of each General Partner, the Additional General Partners and the
approval of holders of more than fifty percent (50%) of the  partnership
interests owned by limited partners calculated based on the limited partners'
share in the profits of the partnership.  If any one partnership fails to
receive approval of the Plan of Combination, the combination transactions will
not be consummated.

                                     -89-
<PAGE>

          For purposes of determining the requisite percentage of partnership
interests, votes will be tabulated based on the percentage interests each
partner, including the General Partner and the Additional General Partner, has
in the profits of the applicable partnership as of the record date.  The table
below sets forth information concerning the percentage interest in each
partnership as of the record date:

         The General Partners and the Additional General Partners intend to
vote in favor of the Plan of Combination.

 Rights of Appraisal


          Under the rules adopted by the NASD, limited partners in roll-up
transactions such as the combination transactions are entitled to appraisal
rights. The right to make an election to receive cash equal to the Appraised
Value of a limited partner's interest is intended to satisfy this requirement.



                    MATERIAL FEDERAL INCOME TAX CONSEQUENCES

 General

          This section summarizes the material Federal income tax consequences
of general application that should be considered by holders of interests in the
partnerships and holders of common stock of Indian and the General Partners,
resulting from their participation in the proposed combination transactions.
This section does not, however, comment on all tax matters that may affect the
partnerships, the General Partners, Indian, Canaan Securities or holders of
interests in the partnerships, holders of the General Partners common stock,
holders of Indian common stock and holders of Canaan Securities common stock,
and this section does not consider various facts or limitations applicable to
any particular participant that may modify or alter the results described in
this document. It may not be applicable to various classes of taxpayers,
including, without limitation, insurance companies, tax-exempt organizations,
financial institutions, securities dealers, broker-dealers, and foreign persons.


                                     -90-
<PAGE>

          Except as otherwise indicated, statements of legal conclusion
regarding tax treatments, tax effects or tax consequences reflect the opinions
of Crowe & Dunlevy, A Professional Corporation, counsel for Canaan and the
General Partners, based on laws, regulations, rulings, practice and judicial
decisions in effect at the date of this document. However, legislative, judicial
or administrative changes or interpretations may be forthcoming that could
repeal, overrule or modify any of these authorities. Any such change could be
retroactive and, accordingly, could alter or modify the statements and
conclusions set forth in this document. No rulings have been requested from the
Internal Revenue Service with respect to any aspect of the proposed combination
transactions. The IRS has announced generally that it will not issue rulings
regarding the tax consequences of transactions similar to the combination
transactions. Furthermore, there can be no assurance that the IRS or the courts
would agree with the conclusions set forth in this discussion below.

          A copy of the tax opinion of Crowe & Dunlevy has been filed as an
exhibit to the registration statement of which this document is a part. Crowe &
Dunlevy's tax opinion is based, in part, on various assumptions of fact and
certificates. Upon receipt of a written request by a limited partner or his
representative designated in writing, a copy of the opinion and related
certificates will be provided promptly, without charge, by Canaan. Please make
any written request to Canaan Energy Corporation, 119 North Robinson, Suite 600,
Oklahoma City, Oklahoma, 73102.


          All persons affected by proposed combination transactions are urged to
consult their own tax advisor as to the particular federal income and other tax
consequences of the combination transactions.

 Limited Partners

          In the combination transactions, a Canaan subsidiary acquisition
corporation will merge with and into each separate partnership. The limited
partners of each merging partnership will receive Canaan common stock based on
their share of the partnership's Exchange Value. Because the merging partnership
survives the merger transaction, each merger will be treated for Federal income
tax purposes as if the limited partners transferred their interests in each
respective merging limited partnership to Canaan in exchange for common stock of
Canaan in a transaction described in Section 351(a) of the Code or for cash.
Each merging partnership will not recognize any gain or loss as a result of each
respective partnership merger.

          A limited partner who receives Canaan common stock in the combination
transactions will not recognize gain or loss as a result of the receipt of the
stock.

          A limited partner who elects to receive cash will recognize gain or
loss equal to the difference between the cash received and his adjusted tax
basis in his partnership interest on the date of the merger.

                                     -91-
<PAGE>

          Gain, if any, recognized by a limited partner will be treated as gain
from the sale or exchange of his interest in the partnership. Therefore, gain
recognized by a limited partner generally will be capital except to the extent
of the cash received in exchange for his share of the partnership's ordinary
income assets, i.e. unrealized receivables and any inventory items. Unrealized
receivables include some types of recapture items, including depreciation,
depletion and intangible drilling costs with respect to deductions previously
taken by the limited partnership.

         A limited partner's basis in Canaan common stock received will be equal
to his aggregate basis in his partnership interest transferred. Such basis will
be prorated among all of the shares of Canaan common stock received.

          The holding period required for long-term capital gain treatment is
one year. In tax-free and partially tax-free exchanges where the relinquished
property is a capital or Section 1231 asset, the Code generally provides that
the holding period of the property received in the exchange includes the holding
period of the property relinquished. However, the IRS has published authority
providing that the holding period of common stock received in a tax-free
exchange for a partnership interest does not include the holding period of the
partnership interest to the extent the value of the common stock received is
attributable to unrealized receivables of the partnership that are neither
capital assets nor Section 1231 assets. If the IRS ruling position applies, the
holding period of a portion of the Canaan common stock received by each limited
partner for the value of the partnership's ordinary income assets will begin on
the day following the date of the exchange, and the holding period for the
remaining portion of the Canaan common stock will include each respective
limited partner's holding period for the partnership interest exchanged
therefor. The IRS cites no authority for its ruling position and, accordingly,
it is questionable whether the IRS ruling position is valid. If a limited
partner takes the position that the general tacking principles apply, the IRS
may assert its ruling position on the examination of a limited partner's federal
income tax return.

          The Code provides special rules suspending a partner's ability to
deduct his allocable share of partnership losses when the partner lacks tax
basis in his partnership interest, the losses are generated by "passive
activities", or by activities with respect to which the partner is not "at
risk."  Following the combination transactions, any prior partnership loss
allocated to a limited partner that was suspended by the at risk rules or by a
lack of basis will continue to be suspended and effectively will be lost.
Losses suspended by the at risk rules, however, should be available to offset
any taxable gain recognized as a result of the combination transactions, as
described above.  Any prior partnership loss allocated to a limited partner that
was suspended by the passive activity loss rules should be available to offset
any gain recognized as a result of the combination transactions, because that
income should be passive income, but will not be available to offset nonpassive
income, including dividends receive on Canaan common stock, until such limited

General

          Canaan, formerly known as Coral Reserves Group, Ltd., is an
independent oil and gas company headquartered in Oklahoma City, Oklahoma. Canaan
was formed in March, 1987, as an Oklahoma corporation, by Leo E. Woodard, who

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

          The following discussion is intended to assist in an understanding of
Canaan's financial position as of December 31, 1998 and 1999, and March 31,
2000, and its results of operations for each year in the three-year period ended
December 31, 1999, and for the three months ended March 31, 1999 and 2000. The
financial statements and notes thereto included elsewhere in this document
contain additional information and should be referred to in conjunction with
this discussion.

General

          Canaan is an Oklahoma corporation formerly known as Coral Reserves
Group, Ltd., organized in March of 1987 for the purpose of originating,
evaluating, engineering, negotiating, closing and managing producing oil and gas
property acquisitions on a contract basis for several limited partnerships
sponsored by others. Since 1990, its primary activities have consisted of
acquiring, developing, producing and operating oil and natural gas properties.
Also, since 1990, when the General Partners began sponsoring partnerships,
Canaan has managed the limited partnerships on behalf of the General Partners.
In February 1999, as a result of the Indian Acquisition Agreement, Canaan has
and will continue to manage Indian's operations until completion of the
combination transactions.

          As a result of the combination transactions, Canaan will acquire all
of the other parties to the combination transactions while the equity owners of
the other parties to the combination transactions will become shareholders of
Canaan. Canaan will continue the combined businesses of the partnerships, the
General Partners and Indian after the completion of the combination transactions
in a manner similar to the business activities of such entities prior to such
transactions.

          Canaan has been continuously engaged in the acquisition, production,
development and operation of oil and natural gas properties.  As of March 31,
2000, Canaan operated 107 of the 129 wells in which it owns an interest.
Operations are located entirely within the state of Oklahoma and are
concentrated in Kingfisher County in north central Oklahoma and Garvin and
McClain counties in south central Oklahoma.  Canaan's net production during the
three months ended March 31, 2000 was approximately 164 Mcfe per day, of which
84% was natural gas. Canaan's production is located entirely within Oklahoma,
except for one lease in Texas.  As of December 31, 1999, the total value of
Canaan's proved oil and gas reserves approximated $500,000.

          Historically, Canaan has utilized cash flows from operations and debt
to fund its capital expenditure programs.  Management intends to fund future
capital expenditures through cash flows from operations and other various
capital markets made possible by the combination transactions.  Canaan believes
that once the combination transactions are complete, it will be better

                                       98
<PAGE>

positioned to pursue many of the prospects resulting from the combination, as
well as projects that are likely to arise as a result of Canaan's ongoing
activities.

          The markets for oil and gas have been volatile and are likely to
remain so in the future. Prices for oil and gas are subject to wide fluctuations
in response to relatively minor changes in the supply and demand for oil and
gas, market uncertainty and a variety of additional factors that are beyond the
control of Canaan. In the future, lower oil and gas prices may reduce
the attractiveness or viability of exploration prospects and the amount of oil
and gas reserves that may be produced economically, Canaan's cash flow from
operations, the amount of outstanding borrowings under Canaan's credit
facilities, and Canaan's net income and capital expenditures.

          Canaan may from time to time enter into certain oil and gas price swap
agreements in an attempt to manage its exposure to oil and gas price volatility.
To the extent Canaan is unable to effect such transactions, continued
fluctuations in oil and gas prices could have an effect on Canaan's operating
results.  Canaan and the combined entities have entered into price swap
contracts to fix the sales price of certain of its oil and gas production for
the remainder of 2000 through May, 2001.

          Canaan uses the full cost method of accounting for its investment in
oil and natural gas properties. Under the full cost method of accounting, all
costs of acquisition, exploration and development of oil and gas reserves are
capitalized into a "full cost pool" as incurred, and properties in the pool are
amortized and charged to operations using the units-of-production method based
on the ratio of current production to total proved oil and gas reserves. To the
extent that such capitalized costs, net of depreciation, and amortization and
deferred income taxes, exceed the present value of estimated future net
revenues, discounted at 10%, from proved oil and gas reserves, after income tax
effects, such excess costs are charged to operations. Once incurred, a write
down of oil and gas properties is not reversible at a later date, even if oil or
gas prices increase.


          During the course of normal operation, Canaan will take more or less
than its respective ownership share of the natural gas volumes produced.  These
volumetric imbalances are monitored over the lives of the wells' production
capability.  If an imbalance exists at the time the wells' reserves are
depleted, cash settlements are made among the joint interest owners under a
variety of arrangements.

          Canaan follows the sales method of accounting for natural gas
imbalances.  A liability is recorded only if Canaan's excess takes of natural
gas volumes exceed its estimated remaining recoverable reserves.  No receivables
are recorded for those wells where Canaan has taken less that its ownership
share of natural gas production.  Canaan's production imbalance position in
terms of volumes and value was not significant as of March 31, 2000.  Such
imbalance position is not expected to significantly impact Canaan's future
operating results or financial position.

Year Ended December 31, 1998 Compared with the Year Ended December 31, 1997

          Revenues. Total revenues for the year ended December 31, 1998 were
$156,535, a decrease of $21,286 from revenues of $177,821 for the year ended
1997.  Revenues from oil and natural gas sales decreased $28,760 to $83,652 in
1998, from $112,412 in 1997.  The primary reason for the decrease in oil and
natural gas sales in 1998 is a result of a significant decrease of $8.56 per
barrel in the average price received for oil in 1998 when compared to 1997, and
a significant decrease of $.46 per Mcf in the average price received for gas in
1998, when compared to 1997.  The average price per barrel of oil and Mcf of gas
received in 1998 and 1997 was $13.52 and $1.98, and $22.08 and $2.44,
respectively.  Production of oil and natural gas was 1,903 Bbls and 29,263 Mcf,
respectively, in 1998, as compared to 1,570 Bbls and 31,828 Mcf, respectively,
in 1997. On an equivalent basis, there was only a slight decrease in production
in 1998, as compared to 1997, resulting from the late 1997 Boswell Acquisition
of producing properties and development activities adding production, offset by
normal declines in production rates, and the sale of marginal wells in 1998.
Canaan acquired producing properties in December 1998 (the Marathon
Acquisition), which did not significantly impact 1998 production.

          Salt water disposal services revenues increased only 4% for the year
ended December 31, 1998, as compared to the same period in 1997, as the salt
water production levels and the number of wells operated by Canaan remained
relatively constant.  Production engineering services revenue increased by
approximately 33% or $5,474 for the year ended December 31, 1998, as compared to
the same period in 1997.  This is a result of an increase in the number of wells
operated in 1998 compared to 1997 resulting from the late 1997 and 1998
acquisitions.  The newly acquired properties required additional operational
field supervision in 1998 due to Canaan's unfamiliarity with the properties.
Operational field supervision is billed by the company to the working interest
owners of its operated wells as production engineering services based on
services provided.

          Approximately 55% of salt water disposal services revenue and 60% of
production engineering services revenue was earned from services provided to the
limited partnerships.  After completion of the combination transactions, salt
water disposal services revenues and production engineering services revenue
will only be recognized for services provided to non-affiliated third parties
who own working interest in producing oil and natural gas properties operated by
Canaan.

          Lease operating expense. Lease operating expense increased $9,801 to
$27,593 in 1998, as compared to $17,792 in 1997, as a result of the continued
operation of marginal wells acquired in the late 1997 Boswell Acquisition which
were plugged in mid-1998. On a Mcfe basis, lease operating expense increased 58%
in 1998 to $0.67 per Mcfe from $0.43 per Mcfe in 1997, due to the reason
discussed above.

          Gross Production Taxes. Gross production taxes decreased 23% to $5,577
in 1998, as compared to $7,213 in 1997. This decrease was a result of a 26%
decrease in oil and natural gas revenues in 1998, as compared to 1997.

                                      100
<PAGE>


          Depreciation and amortization expense.  Depreciation and amortization
expense decreased $10,954 to $48,350 in 1998, from $59,304 in 1997. Depreciation
and amortization expense from oil and natural gas properties increased only
slightly to $29,700 in 1998, as compared to $29,084 in 1997. The depreciation
and amortization expense rate increased to $0.73 per Mcfe for 1998, from $0.71
per Mcfe for 1997, as net oil and natural gas properties costs changed only
slightly and production rates compared to proved reserves were consistent with
1997. Depreciation and amortization expense resulting from non-oil and natural
gas properties decreased $11,654 as a result of assets being fully depreciated
in 1996 and 1997.

          General and administrative expense.  Net general and administrative
expense increased $58,077 to $(33,780) in 1998, as compared to $(91,857) in
1997. Gross general and administrative expense decreased 27% to $936,720 in
1998, from $1,281,169 in 1997.  Gross general and administrative expense
decreased primarily as a result of decreased salaries and bonuses of $260,000 in
1998, compared to 1997, due to lower levels of earnings in 1998.  Also impacting
the decrease was a $122,000 increase in general and administrative costs
recovered from the other working interest owners in 1998, compared to 1997.
This increase resulted from an increase in the reimbursement rates Canaan was
able to charge to the other interest owners in 1998, compared to 1997 and an
increase in the number of operated properties in 1998, compared to 1997.  The
decrease in gross general and administrative expenses were offset by a $402,500,
or 29% decrease in the management fees Canaan earns from the partnerships it
manages in behalf of the General Partners. The management fees are based
primarily on the General Partners' net distributable cash flows from the limited
partnerships.  Therefore, the decrease in the 1998 management fees is
attributable to the decrease in the net distributable cash flows from the
limited partnerships.

          Income taxes.  Income tax expense decreased $22,000 to $46,000 in 1998
from $68,000 in 1997.  The change in tax expense was due to a $73,089 decrease
in earnings before income taxes in 1998 compared to 1997.  Canaan's effective
tax rate was 31% and 30% in 1998 and 1997, respectively.


Year Ended December 31, 1999 Compared with the Year Ended December 31, 1998


          Revenues. Total revenues for the year ended December 31, 1999 were
$199,857, a 28% increase as compared to revenues of $156,535 for the year ended
December 31, 1998. Revenues from oil and natural gas sales increased 68% or
$56,794 to $140,446 in 1999, from $83,652 in 1998.  One reason for the increase
in oil and natural gas sales in 1999 is a significant increase of $4.58 per
barrel and $.42 per Mcf in the average price received for oil and gas,
respectively, in 1999, when compared to 1998.  The average price per barrel of
oil and Mcf of gas received in 1999 and 1998 was $18.10 and $2.40, and $13.52
and $1.98, respectively.  Production of oil and natural gas was 1,585 barrels
and 46,506 Mcf, respectively, in 1999, as compared to 1,903 Bbls and 29,263 Mcf,
respectively, in 1998. On an equivalent basis, there was a 38% increase in
production in 1999, as compared to 1998, as a result of drilling and completing
one

                                     -101-
<PAGE>


significant natural gas well in April 1999, and the acquisition of producing
properties from Marathon in December 1998.

          Revenues from salt water disposal services decreased $3,000 to $48,000
for the year ended December 31, 1999, from $51,000 for the same period in 1998.
The decrease is a result of small changes in salt water production levels from
period to period.  Production engineering services revenue decreased by $10,472
for the year ended December 31, 1999, as compared to the same period in 1998.
In 1998, additional time was required in the field by the company's manager of
operations resulting from the acquisition of operated properties in late 1997
and 1998.  In 1999, the amount of time required in the field by the manager of
operations was significantly reduced due to improved operating efficiencies of
the operated properties acquired in late 1997 and 1998.

          Approximately 57% of salt water disposal services revenue and 60% of
production engineering services revenue was earned from services provided to the
limited partnerships.  After completion of the combination transactions, salt
water disposal services revenues and production engineering services revenue
will only be recognized for services provided to non-affiliated third parties
who own working interest in producing oil and natural gas properties operated by
Canaan.

          Lease operating expense. Lease operating expense decreased $11,332 to
$16,261 in 1999, as compared to $27,593 in 1998, as a result of the cessation of
operations of the marginal wells acquired in the 1997 Boswell Acquisition which
were plugged in mid-1998.  On a Mcfe basis, lease operating expense decreased
57% in 1999 to $.29 per Mcfe from $0.67 per Mcfe in 1998 due to a significant
increase in production from the drilling and completion of a significant natural
gas well in April 1999, and the December 1998 Marathon Acquisition, and as a
result of the reduction in lease operating expenses as discussed above.

          Gross Production Taxes. Gross production taxes increased $6,693 to
$12,270 in 1999 as compared to $5,577 in 1998. This increase was a result of a
68% increase in oil and natural gas revenues in 1999 as compared to 1998.

          Depreciation and amortization expense.  Depreciation and amortization
expense increased $7,413 to $55,763 in 1999, from $48,350 in 1998.  Depreciation
and amortization expense from oil and natural gas properties increased $15,071
to $44,771 in 1999, as compared to $29,700 in 1998.  This increase was a result
of increased oil and natural gas property costs and an increase in production
rates compared to proved reserves in 1999 compared to 1998.  Depreciation and
amortization expense rate increased to $.80 per Mcfe for 1999 from $0.73 per
Mcfe for 1998 as a result of the above discussion.  Depreciation and
amortization expense resulting from non-oil and natural gas properties decreased
$7,658 as a result of additional assets being fully depreciated in 1999 at the
end of 1998.

          General and administrative expense.  Net general and administrative
expense increased $58,922 to $25,142 in 1999, as compared to $(33,780) in 1998.
Gross general and administrative expense decreased $55,578 to $881,142 in 1999
from $936,720 in 1998.  This

                                      102
<PAGE>


resulted from an increase of $105,000 in general and administrative costs
recovered from the other working interest owners in 1999 as compared to 1998
resulting from the increase in operated properties acquired in late 1998.  Also
increasing the general and administrative costs recovered was a 5.8% increase in
recovery rates charged to other working interest owners in 1999.  Offsetting
this increase was an increase in salary and related costs resulting from
increased staffing needs. The increase in net general and administrative
expenses was attributable to a 13% decrease in the management fees Canaan earns
from the partnerships it manages on behalf of the General Partners. The
management fees are based primarily on the General Partners' net distributable
cash flows from the limited partnerships.  Therefore, the decrease in the 1999
management fees is attributable to the decrease in the net distributable cash
flows from the limited partnerships.

          Income taxes.  Income tax expense decreased $7,000 to $39,000 in 1999,
from $46,000 in 1998.  The change in tax expense was due to the decrease in
earnings before income taxes in 1999, compared to 1998.  Canaan's effective tax
rate was 31% in 1999 and 1998, respectively.


Three Months Ended March 31, 2000 Compared with the Three Months Ended March 31,
1999

          Revenues. Total revenues for the three months ended March 31, 2000
were $58,756, a 89% increase as compared to revenues of $31,102 for the three
months ended March 31, 1999. Revenues from oil and natural gas sales increased
161% or $23,285 to $37,740 for the three months ended March 31, 2000, from
$14,455 for the same period in1999. One reason for the increase in oil and
natural gas sales for the three months ended March 31, 2000 was a significant
increase of $12.18 per barrel and $0.67 per Mcf in the average price received
for oil and gas, respectively, for the three months ended March 31, 2000
compared to the same period in 1999. The average price per barrel of oil and Mcf
of gas received for the three months ended March 31, 2000 and 1999 was $24.07
and $2.28 and $11.89 and $1.61, respectively.  Production of oil and natural gas
was 390 barrels and 12,433 Mcf, respectively, for the three months ended March
31, 2000, as compared to 310 barrels and 6,705 Mcf, respectively, for the same
period in 1999.  On an equivalent basis, there was a 72% increase in production
for the three months ended March 31, 2000, as compared to the same period in
1999, as a result of drilling and completing one significant natural gas well in
April, 1999.

          Revenues from salt water disposal services increased $4,000 to $16,000
for the three months ended March 31, 2000, from $12,000 for the same period in
1999.  The increase is a result of small changes in salt water production levels
from period to period.  Production engineering services revenue increased only
slightly for the three months ended March 31, 2000, as compared to the same
period in 1999.

                                      103
<PAGE>


          Approximately 58% of salt water disposal services revenue and 42% of
production engineering services revenue was earned from services provided to the
limited partnerships.  After completion of the combination transactions, salt
water disposal services revenues and production engineering services revenue
will only be recognized for services provided to non-affiliated third parties
who own working interest in producing oil and natural gas properties operated by
Canaan.

          Lease operating expense. Lease operating expense increased $1,085 to
$4,225 for the three months ended March 31, 2000, as compared to $3,140 for the
three months ended March 31, 1999, as a result of costs associated with the
operating costs of a significant natural gas well drilled and completed in
April, 1999.  On a Mcfe basis, lease operating expense decreased 22% to $.29 for
the three months ended March 31, 2000, as compared to $.37 per Mcfe during the
same period in 1999 due to a 72% increase in production on an Mcfe basis.

          Gross Production Taxes. Gross production taxes increased $2,045 to
$2,670 for the three months ended March 31, 2000, as compared to $625 for the
three months ended March 31, 1999.  This increase was a result of a 161%
increase in oil and natural gas revenues for the three months ended March 31,
2000, as compared to the same period in 1999.  In addition, during the three
months ended March 31, 1999, the company recognized some gross production tax
credits not available in the same period in 2000.

          Depreciation and amortization expense.  Depreciation and amortization
expense increased $5,756 to $14,338 for the three months ended March 31, 2000,
from $8,582 for the same period in 1998.  Depreciation and amortization expense
from oil and natural gas properties increased $6,166 to $12,010 for the three
months ended March 31, 2000, as compared to $5,834 for the three months ended
March 31, 1999.  This increase was a result of an increase in production rates
compared to proved reserves for the three months ended March 31, 2000 compared
to the same period in 1999.  The depreciation and amortization rate increased to
$.81 per Mcfe for the three months ended March 31, 2000, as compared to $.68 for
the same period in 1999 as a result of the above discussion.

          General and administrative expense.  Net general and administrative
expense increased $46,499 to $8,634 for the three months ended March 31, 2000,
as compared to $(37,865) for the three months ended March 31, 1999. Gross
general and administrative expense increased $148,499 to $297,634 for the three
months ended March 31, 2000, from $149,135 for the same period in 1999.  $45,000
of the increase is a result of accounting fees incurred during the three months
ended March 31, 2000, which are not directly related to the combination
transactions.  The other increases are a result of increases in salary related
costs caused by salary level increases and an increase in personnel for the
three months ended March 31, 2000, compared to the same period in 1999.  This
increase in gross general and administrative expense was partially offset by an
increase of $10,000 in general and administrative expenses recovered from the
other working interest owners in the three months ended March 31, 2000, as
compared to the same period in 1999.  The increase in gross general and
administrative expense was also offset by a $102,000 or 55% increase in the
management fees Canaan earns from the partnerships it manages on behalf of

                                     -104-
<PAGE>


the General Partners.  The management fees are based primarily on the General
Partners' net distributable cash flows from the limited partnerships.
Therefore, the increase in the management fee is attributable to an increase in
the limited partnerships' net distributable cash flows for the three months
ended March 31, 2000, compared to the same period in 1999.

          Income taxes.  Income tax expense decreased $8,000 to $13,000 for the
three months ended March 31, 2000, from $21,000 for the same period in 1999.
The change in tax expense is due to a decrease in earnings before income taxes
for the three months ended March 31, 2000, compared to the same period in 1999
for the reasons discussed above.  Canaan's effective tax rate approximated 31%
for the three months ended March 31, 2000 and 1999, respectively.

Capital Expenditures, Capital Resources and Liquidity

          As of December 31, 1999 and 1998, Canaan had cash balances of $587,680
and $749,538, respectively.  The decrease in working capital to $238,443 as of
December 31, 1999, from $369,930 as of December 1998, relates primarily to an
increase of approximately $107,000 in capital expenditures and $258,000 of costs
incurred related to the combination transactions in 1999, as compared to the
same period in 1998.  This decrease was offset by an increase in accounts
receivable at December 31, 1999 compared to December 31, 1998, resulting from
increased levels of acquiring oil and gas assets on behalf of the limited
partnerships. Also offsetting the decrease is an increase of current deferred
tax assets as of December 31, 1999, compared to December 31, 1998. The decrease
in working capital of $262,408 to $(23,965) for the three months ended March 31,
2000, as compared to $238,443 for the period ending 1999 reflects mainly an
increased level of costs incurred in connection with the combination
transactions during the three months ended March 31, 2000.

          For 1999, net cash provided by operating activities was $32,509, as
compared to $416,062 in 1998. The decrease in net cash provided by operating
activities in 1999 as compared to 1998, relates primarily to the timing and
disbursements of payments made for accounts payable, accrued expenses and other
liabilities and the changes in operating results in 1999 compared to 1998,
discussed above.  For the three months ended March 31, 2000, net cash used in
operating activities was $223,882 as compared to $314,495 for the same period in
1999. This decrease in net cash used in operating activities for the period
ended March 31, 2000, as compared to the same period in 1999, relates primarily
to timing and disbursements of payments made for accounts payable, accrued
expenses and other liabilities and the changes in operating results during the
three months ended March 31, 2000, compared to the same period in 1999,
discussed above.

          Net cash used in investing activities in 1999 was $194,367, as
compared to $26,796 for the same period in 1998.  This was a result of drilling
and completing a significant natural gas well in April, 1999 and costs
associated with the proposed combination transactions incurred during 1999.  Net
cash used in investing activities for the three months ended March 31, 2000, was
$80,109, as compared to $9,752 for the same period in 1999.  Again, this was
mainly a result of costs associated with the proposed combination transactions
incurred during 2000.

          Capital expenditures. Canaan's capital expenditures to date have
focused primarily on the development of oil and natural gas properties in
Oklahoma and to a lesser extent on acquisitions of proved developed producing
oil and natural gas properties located in Oklahoma.

          Canaan's capital expenditures to date have been financed with cash
flow provided by operations.  After completion of the combination transactions,
Canaan's capital expenditures will increase.  The actual level of capital
expenditures and the allocation of such expenditures have not been specifically
determined.

          Capital Resources.  Canaan's cash requirements have been met primarily
in the past through cash generated from operations.  See "Business of Canaan
After Completion of the Combination Transactions" elsewhere in this document for
a discussion of Canaan's anticipated future capital resources.

          Liquidity.  Canaan intends to meet the remainder of its 2000 capital
requirements primarily from existing cash balances, cash flow from operations,
and subsequent to the combination, with funding under a credit facility.
Canaan's cash flow from operations will be dependent upon its future
performance, which will be subject to prevailing economic conditions and to
financial and business conditions and other factors, many of which are beyond
its control. At some point, Canaan also intends to seek additional capital
through offerings of equity securities. Canaan, as needed will also seek
additional financing through its credit facility available subsequent to the
completion of the combination transactions.  There can be no assurance, however,
that the lenders will extend or increase the borrowing limits under the credit
facility or that such offerings can be successfully completed. Should sufficient
financing not be available from these or other sources, implementation of
Canaan's business plan would be delayed and, accordingly, Canaan's growth
strategy could be adversely affected.

          Canaan does not intend to pay dividends on its common stock in the
near future. Earnings generated will be redeployed by Canaan as it continues its
growth strategies.

(1)      Because of depletion (which is usually higher in the early years of
         production), a portion of every distribution of revenues from
         properties represents a return of a limited partner's original
         investment. Until a limited partner receives cash distributions equal
         to his original investment, 100% of such distributions may be deemed to
         be a return of capital.

(1)    Because of depletion (which is usually higher in the early years of
       production), a portion of every distribution of revenues from properties
       represents a return of a limited partner's original investment. Until a
       limited partner receives cash distributions equal to his original
       investment, 100% of such distributions may be deemed to be a return of
       capital.

      production), a portion of every distribution of revenues from properties

/(1)/    Because of depletion (which is usually higher in the early years of
         production), a portion of every distribution of revenues from
         properties represents a return of a limited partner's original
         investment. Until a limited partner receives cash distributions equal
         to his original investment, 100% of such distributions may be deemed to
         be a return of capital.

(1)      Because of depletion (which is usually higher in the early years of
         production), a portion of every distribution of revenues from
         properties represents a return of a limited partner's original
         investment. Until a limited partner receives cash distributions equal
         to his original investment, 100% of such distributions may be deemed to
         be a return of capital.

                          INFORMATION CONCERNING INDIAN

General

          Indian is an Oklahoma corporation founded in 1981 and engaged in the
exploration, development and production of natural gas, and to a lessor extent,
crude oil. In addition to the above activities, Indian has made significant
acquisitions of producing oil and natural gas properties during the last 19
years. The most significant acquisition was in December 1997. For approximately
$30.2 million, Indian acquired producing Oklahoma and western Arkansas
properties. Indian funded the purchase through borrowings under a line of credit
and term note.

          As of March 31, 2000, Indian operated 94 of the 307 wells in which it
owns a working interest. Operations are concentrated in Oklahoma and Arkansas.
Total net production is 10,988 Mcf/day of natural gas and 171 Bbls/day of oil
and condensate as of March 31, 2000. The company's production is located
primarily in Oklahoma and western Arkansas, with minor amounts of production in
Kansas and Texas. As of December 31, 1999, total net proved reserves are 57.4
Bcfe of which 93% was natural gas, with proved developed reserves representing
66% of the total and proved undeveloped reserves accounting for 34% of the
total. The total Present Value of Indian's proved reserves has been estimated at
$37.6 million as of December 31, 1999.

          Indian has an inventory of 70 proved undeveloped locations to be
drilled. Of these locations, 64 are located in Oklahoma, primarily in the Strong
City field in the Anadarko Basin of western Oklahoma. The remaining six
locations are in the Massard field of western Arkansas, but they represent 53%
of the total proved undeveloped reserve value.

          On March 31, 2000, Indian sold minor properties consisting of
nonoperated interests in approximately 183 gross wells or 18.38 net wells with
an aggregate Reserve Value of approximately $1.5 million. Because Reserve Values
have been established as of September 30, 1999 and these properties were
included, no adjustment to Indian's Exchange Value will be made to reflect this
sale.

                  BUSINESS OF CANAAN AFTER COMPLETION OF THE
                           COMBINATION TRANSACTIONS

General

     Canaan will become an independent publicly held oil and gas company after
the completion of the combination transactions.

     Canaan will seek growth through an active development drilling program,
identification and development of extension prospects and impact acquisitions.
The company will utilize in-house geological and engineering expertise to
identify and evaluate prospective locations, whether proved or unproved.
Aggressive land strategies will be employed to increase ownership in existing
properties with development potential and to obtain acreage in areas of interest
through acquisitions, leases or farm-ins. Canaan will concentrate its efforts in
the Mid-Continent area, with a preference for natural gas producing properties,
and will seek operations whenever possible.

     On a pro forma basis as of December 31, 1999, Canaan operates 201 of the
965 wells in which it owns a working interest, and these wells represent 38% of
total net production. Pro forma total net production is 20,734 Mcf/day of
natural gas and 580 Bbls/day of oil and condensate as of March 31, 2000. As
indicated below, total net reserves are 103.6 Bcfe, of which 88% are natural
gas, with proved developed reserves representing 76% of the total and proved
undeveloped reserves accounting for 24% of the total as indicated below:

     There are numerous uncertainties inherent in estimating quantities of
proved reserves, including many factors beyond our control or the control of the
reserve engineers. Reserve engineering is a subjective process of estimating
underground accumulations of oil and gas that cannot be measured in an exact
manner, and the accuracy of any reserve or cash flow estimate is a function of
the quality of available data and of engineering and geological interpretation
and judgment. Estimates by different engineers often vary, sometimes
significantly. In addition, physical factors, such as the results of drilling,
testing and production subsequent to the date of an estimate, as well as
economic factors, such as an increase or decrease in product prices that renders
production of such reserves more or less economic, may justify revision to such
estimates. Accordingly, reserve estimates are different from the quantities of
oil and gas that are ultimately recovered.

     Neither Canaan nor any other Combining Entity has filed any reports with
other federal agencies which contain an estimate of their net proved oil and gas
reserves.

     Independent engineering has confirmed an inventory of 110 proved
undeveloped locations. The greatest areas of interest are 80 locations in the
Strong City field, located in the Anadarko Basin of western Oklahoma, and six
high-value locations in the Massard field, located in the Arkoma Basin of
western Arkansas. The Golden Trend in south central Oklahoma will also be an
area of interest.

     Canaan has no plans to sell any of the properties acquired in the
combination transactions and has not identified any specific properties to
acquire.

 Marketing

          The ability of Canaan to market oil and gas often depends on factors
beyond its control.  The potential effects of governmental regulation and market
factors, including alternative domestic and imported energy sources, available
pipeline capacity, and general market conditions are not entirely predictable.

          Natural Gas.  Natural gas is generally sold pursuant to individually
negotiated gas purchase contracts, which vary in length from spot market sales
of a single day to term agreements that may extend several years.  Customers who
purchase natural gas include marketing affiliates of the major pipeline
companies, natural gas marketing companies, and a variety of commercial and

                                     -139-
<PAGE>

public authorities, industrial, and institutional end-users who ultimately
consume the gas. Gas purchase contracts define the terms and conditions unique
to each of these sales. The price received for natural gas sold on the spot
market may vary daily, reflecting changing market conditions. The deliverability
and price of natural gas are subject to both governmental regulation and supply
and demand forces. During the past several years, regional surpluses and
shortages of natural gas have occurred, resulting in wide fluctuations in prices
achieved. During 1999, the average monthly gas prices received by the Combining
Entities ranged from $1.89 to $2.46 per mcf.

     The lengths of the contracts vary widely. Substantially all of Canaan's gas
will be sold under contracts providing for market sensitive terms.

     During the past several years, an overabundance of natural gas supplies and
the promulgation of state and federal regulations pertaining to the sale,
transportation, and marketing of natural gas resulted in increasing competition
and declining prices. It is likely that supply and demand factors will continue
to be the driving force in the changing marketplace.

     Crude Oil. Oil produced from Canaan's properties will be sold at the
prevailing field price to one or more of a number of unaffiliated purchasers in
the area. Generally, purchase contracts for the sale of oil are cancelable on
30-days notice. The price paid by these purchasers is generally an established,
or "posted," price that is offered to all producers. During 1999, the average
monthly prices received by the Combining Entities ranged from $16.54 to $18.19
per barrel. During the last several years prices paid for crude oil have
fluctuated substantially. Future oil prices are difficult to predict due to the
impact of worldwide economic trends, coupled with supply and demand variables,
and such non-economic factors as the impact of political considerations on OPEC
pricing policies and the possibility of supply interruptions. Oil production
comprised approximately 14% of Canaan's total pro forma oil and gas production
calculated on an equivalent Mcf basis for 1999. Therefore, an increase or
decrease in oil prices has a minimal effect on revenues when compared to the
effect on the price of natural gas.

Competition

     The oil and natural gas industry is intensely competitive. Competition is
particularly intense in the acquisition of prospective oil and natural gas
properties and oil and gas reserves. Canaan's competitive position depends on
our geological, geophysical and engineering expertise, our financial resources,
our ability to develop properties and our ability to select, acquire and develop
proved reserves. We compete with a substantial number of other companies having
larger technical staffs and greater financial and operational resources. Many
such companies not only engage in the acquisition, exploration, development and
production of oil and natural gas reserves, but also carry on refining
operations, generate electricity and market refined products. We also compete
with major and independent oil and gas companies in the marketing and sale of
oil and gas to transporters, distributors and end users. The oil and natural gas
industry competes with other industries supplying energy and fuel to industrial,
commercial and individual

                                     -140-
<PAGE>

consumers. Canaan also competes with other oil and natural gas companies in
attempting to secure drilling rigs and other equipment necessary for drilling
and completion of wells. Such equipment may be in short supply from time to
time. Finally, companies not previously investing in oil and natural gas may
choose to acquire reserves to establish a firm supply or simply as an
investment. Such companies also provide competition for Canaan.

     Canaan's business is affected not only by such competition, but also by
general economic developments, governmental regulations and other facts that
affect out ability to market our oil and natural gas production. The prices of
oil and natural gas realized by Canaan are highly volatile. The price of oil is
generally dependent on world supply and demand, while the price we receive for
our natural gas is tied to the specific market sin which such gas is sold.
Declines in crude oil prices or natural gas prices adversely impact Forest's
activities. Our financial position and resources may also adversely affect our
competitive position. Lack of available funds or financing alternatives will
prevent us from executing our operating strategy and from deriving the expected
benefits therefrom.

Regulation

     Exploration and Production. The exploration, production and sale of oil and
gas are subject to various types of local, state and federal laws and
regulations. These laws and regulations govern a wide range of matters,
including the drilling and spacing of wells, allowable rates of production,
restoration of surface areas, plugging and abandonment of wells and requirements
for the operation of wells. These regulations may adversely affect the rate at
which wells produce oil and gas.

     Environmental Matters. The discharge of oil, gas or other pollutants into
the air, soil or water may give rise to liabilities to the government and third
parties and may require Canaan to incur costs to remedy discharges. Natural gas,
oil or other pollutants, including salt water brine, may be discharged in many
ways, including from a well or drilling equipment at a drill site, leakage from
pipelines or other gathering and transportation facilities, leakage from storage
tanks and sudden discharges from damage or explosion at natural gas facilities
of oil and gas wells. Discharged hydrocarbons may migrate through soil to water
supplies or adjoining property, giving rise to additional liabilities.

     A variety of federal and state laws and regulations govern the
environmental aspects of natural gas and oil production, transportation and
processing and may, in addition to other laws, impose liability in the event of
discharges, whether or not accidental, failure to notify the proper authorities
of a discharge, and other noncompliance with those laws. Compliance with such
laws and regulations may increase the cost of oil and gas exploration,
development and production, although the Company does not currently anticipate
that compliance will have a material adverse effect on capital expenditures or
earnings of Canaan. Failure to comply with the requirements of the applicable
laws and regulations could subject Canaan to substantial civil and/or criminal


                                     -141-
<PAGE>

penalties and to the temporary or permanent curtailment or cessation of all or a
portion of our operations.

     Canaan does not believe that its environmental risks will be materially
different from those of comparable companies in the oil and gas industry. Canaan
believes the present activities of the Combining Entities substantially comply,
in all material respects, with existing environmental laws and regulations.
Nevertheless, Canaan cannot assure you that environmental laws will not result
in a curtailment of production or material increase in the cost of production,
development or exploration or otherwise adversely affect Canaan's financial
condition and results of operations. Although Canaan maintains liability
insurance coverage for liabilities from pollution, environmental risks generally
are not fully insurable.

     Marketing and Transportation. The interstate transportation and sale for
resale of natural gas is regulated by the Federal Energy Regulatory Commission
under the Natural Gas Act of 1938. The sale and transportation of natural gas
also is subject to regulation by various state agencies. The Natural Gas
Wellhead Decontrol Act of 1989 eliminated all gas price regulation effective
January 1, 1993. In addition, FERC recently has proposed several rules and
orders concerning transportation and marketing of natural gas. We cannot predict
the impact of these rules and other regulatory developments on Canaan.

     In 1992, FERC finalized Order 636, and also has promulgated regulations
pertaining to the restructuring of the interstate transportation of natural gas.
Pipelines serving this function have since been required to "unbundle" the
various components of their service offerings, which include gathering,
transportation, storage, and balancing services. In their current capacity,
pipeline companies must provide their customers with only the specific service
desired, on a non-discriminatory basis. Although Canaan is not an interstate
pipeline, Canaan believes the changes brought about by Order 636 have increased
competition in the marketplace, resulting in greater market volatility.

     Various rules, regulations and orders, as well as statutory provisions may
affect the price of natural gas production and the transportation and marketing
of natural gas.

Operating Hazards and Uninsured Risks

     Canaan's oil and gas operations are subject to all operating hazards and
risks normally incident to drilling for and producing oil and gas, such as
encountering unusual formations and pressures, blow-outs, environmental
pollution, and personal injury. Canaan will maintain such insurance coverage as
it believes to be appropriate, taking into account the size of Canaan and its
proposed operations. Canaan currently does not maintain insurance coverage for
physical loss or damage to equipment located on the wells or for selected
properties, such as crude oil stored in tanks. Canaan's insurance policies also
have standard exclusions. Losses can occur from an uninsurable risk or in
amounts more than existing insurance coverage. The occurrence of

                                     -142-
<PAGE>

an event which is not insured or not fully insured could have an adverse impact
on Canaan's revenues and earnings.

Employees

     At March 31, 2000, on a pro forma basis Canaan had 23 full and part-time
employees in its Oklahoma City headquarters and eight employees in various field
offices. None of these employees is represented by a union and Canaan believes
that it maintains good relations with its employees. After consummation of the
combination transactions, Canaan expects to add nine additional office employees
to manage its greater size.

Facilities

     Canaan currently leases 5,867 square feet in downtown Oklahoma City for its
corporate headquarters and expects to add additional space after consummation of
the combination transactions.

Legal Proceedings

     Canaan expects to be involved from time to time in various legal and
administrative proceedings and threatened legal and administrative proceedings
incidental to the ordinary course of its business. Neither Canaan nor any of the
Combining Entities is now involved in any litigation, individually or in the
aggregate, which could have a material adverse effect on Canaan's business,
financial condition, results of operations, or cash flows.

Capitalization

     The following table sets forth as of March 31, 2000 the pro forma
capitalization of Canaan giving effect to the combination transactions assuming
consummation of the combination transactions as of such date and no limited
partners elect to receive cash or exercise dissenters rights. The table also
reflects the pro forma capitalization assuming that limited partners elect to
receive cash or exercise dissenters rights to the maximum $15.0 million limit.

Credit Facilities

     As a result of the combination transactions, Canaan expects to succeed to
the obligations of Indian on its senior bank debt under a secured credit
facility provided by Bank One, Oklahoma, N.A., unless Canaan elects to seek
similar financing from another commercial lender. The Bank One credit facility
provides for a line of credit of up to $50 million, subject to a borrowing base
which is based on a periodic valuation of oil and gas reserves (the "Borrowing
Base"). The amount of credit available to Indian at any time under the credit
facility is the lesser of the Borrowing Base or the amount of commitment. As of
March 31, 2000, Indian's Borrowing Base was $20 million. Canaan expects that
its borrowing base under the Bank One credit facility will be increased
significantly upon consummation of the combination transactions based on its pro
forma reserves to make available sufficient funds for its general corporate
purposes. The credit facility has a maturity date of January 15, 2001, which
Canaan expects to extend upon consummation of the combination transactions.
Indian has, and Canaan expects to have, the option of either borrowing at the
LIBOR rate plus a margin currently ranging from 2.5% to 2.75%

                                     -144-
<PAGE>

depending on the amount of advances outstanding in relation to the Borrowing
Base or at a base rate which will approximate the prime rate. Indian is
obligated to make monthly principal payments in amounts determined by Bank One
after taking into consideration the expected reductions in the borrowing base as
a result of production. Indian's most recent determination of the Borrowing Base
was as of January 15, 2000 and Indian is currently making monthly principal
reductions in the amount of $215,000. Canaan expects that the monthly principal
reduction amount will be reset at the completion of the combination transactions
based on Canaan's Borrowing Base which will lead to a material reduction in the
required principal payments.

     The Bank One credit facility contains various affirmative and restrictive
covenants. These covenants, among other things, limit additional indebtedness,
sales of assets, mergers and consolidations, dividends and distributions and
require the maintenance of certain financial ratios. Borrowings under the Indian
agreement with Bank One are secured by substantially all of Indian's oil and gas
properties and Canaan expects that such security arrangements will remain in
effect following consummation of the combination transactions with the addition
of Coral Group properties to the security.

     Funding for any cash payments to be made to Placing Brokers or to limited
partners electing to receive cash or exercising dissenters rights are expected
to be provided under the Bank One credit facility. In addition, the partnerships
collectively are indebted to Bank One in the amount of $7.327 million as of
March 31, 2000 under separate individual partnership loans. Canaan expects to
repay these obligations at the closing with advances under the Bank One credit
facility.

     Indian also has outstanding $6.376 million in debt to Mid-First Bank which
matures on March 1, 2001. On July 1, 2000, Indian is obligated to make an
interim principal payment of $376,000 plus accrued interest. Thereafter,
interest only is payable quarterly commencing September 30, 2000 until maturity.
The Mid-First debt is subordinate and junior to the Bank One debt. The Mid-First
debt bears interest at the rate of the prime rate as published in The Wall
Street Journal which was 8.25% at March 31, 2000 and is secured by the personal
guarantees of certain Indian shareholders, the security for which is limited to
the guarantor's stock and other securities of an affiliated company, and a
corporate guaranty from this same affiliated company that is secured by a pledge
of certain of its investment accounts. The personal guarantees and pledges are
required to be released as a part of the combination transactions. Canaan
expects that it will borrow under the Bank One facility to repay Mid-First upon
consummation of the combination transactions or will negotiate a further
extension of payment of the Mid-First debt.

     Pro forma total long term debt outstanding as of March 31, 2000 will be
$31.578 million, assuming no limited partners elect to exercise dissenters'
rights and Canaan's pro forma long term debt as a percentage of its total pro
forma capitalization will be 56%. Canaan believes that the borrowing capacity
that will be available under the Bank One credit facility, combined with the
company's internal cash flows, will be adequate to finance the initial capital
expenditure

                                     -145-
<PAGE>

programs of Canaan. Repayment of the Bank One credit facility will be made from
cash flow from operations.

 Financing Plans

          Canaan intends to finance its growth through various methods,
including bank debt and public and private offerings of equity and debt
securities.  Canaan believes that a public offering of its common stock would be
desirable in order to improve the trading market for its common stock and to
raise additional capital for specified purposes.  Canaan expects to complete a
public offering of its common stock after closing of a combination transaction
when Canaan determines market conditions are desirable for such purpose and an
appropriate use of proceeds can be determined.

 Quantitative and Qualitative Disclosures about Market Risk

          The following information provides quantitative and qualitative
information about Canaan's potential exposure to market risks.  The term "market
risk" refers to the risk of loss arising from adverse changes in oil and gas
prices and interest rates.  The disclosures are not meant to be precise
indicators of expected future losses, but rather indicators of reasonably
possible losses.  All of the historical market risk sensitive instruments
entered into by Indian and the partnerships were for purposes other than
trading.

          Commodity Price Risk.  Canaan's major market risk exposure will be in
the pricing applicable to its oil and gas production.  Realized pricing will be
primarily driven by the prevailing worldwide price for crude oil and spot market
prices applicable to its U.S. natural gas production. Pricing for oil and gas
production has been volatile and unpredictable for several years.

          Indian and the partnerships have entered into, and Canaan expects to
periodically enter into, financial hedging activities with respect to a portion
of projected oil and gas production through financial price swaps whereby they
receive a fixed price for production and pay a variable market price to the
contract counterparty.  These financial hedging activities are intended to
reduce exposure to oil and gas price fluctuations.  Realized gains or losses
from the settlement of these financial hedging instruments are recognized in oil
and gas sales when the associated production occurs.  The gains and losses
realized as a result of these hedging activities are substantially offset in the
cash market when the hedged commodity is delivered.

          During 1999, the partnerships and Indian entered into financial oil
and gas price hedging instruments which represented approximately 3,001,950
MMBtu of gas production during the period from April 1, 1999 to December 31,
1999 at the rate of 333,550 MMBtu per month at a weighted average price of $2.01
per MMBtu.  The hedged gas volumes represented approximately 33% of pro forma
combined total production for the year ending December 31, 1999.

</TABLE>

          These arrangements hedged approximately 53% of Canaan's pro forma
combined estimated production on an Mcfe basis for the balance of calendar year
2000 based on the Netherland Sewell reserve reports.

          Interest Rate Risk.  On a pro forma combined basis, Canaan had long-
term debt outstanding of $31.578 million as of March 31, 2000.  All of the debt
outstanding at March 31, 2000 bears interest at floating rates which averaged
8.52% as of March 31, 2000. A 10% increase in short-term interest rates on
the floating-rate debt outstanding at December 31, 1999 would equal
approximately 85 basis points. Such an increase in interest rates would have
increased Canaan's interest expense on a pro forma basis for 1999 and the first
three months by approximately $261,000 and $69,000, respectively.

          The above sensitivity analysis for interest rate risk excludes
accounts receivable, accounts payable and accrued liabilities because of the
short-term maturity of such instruments.

                                     -148-
<PAGE>

     Leo E. Woodard

Change in Control Agreements

          Canaan has entered into agreements with Messrs. Woodard, Penton,
Mewbourn and Henson providing for the payment of severance benefits upon
involuntary termination of such persons, other than for cause, within two years
after a Change in Control (as defined in these agreements) of Canaan, including
constructive termination as a result of certain changes in duties or reduction
of compensation.  Canaan expects to enter into similar agreements with other
officers including Mr. Lasuzzo, if he is employed.  The agreements are intended
to promote the retention of these officers by providing them with an extra
measure of financial security in the event of a Change of Control of Canaan.  In
the event of involuntary termination within two years after a Change in Control,
the agreements provide that the officers will receive a lump sum severance
payment equal to three times the officers' annual compensation defined as annual
salary immediately prior to the Change in Control plus the highest annual bonus
received by the officer in the three years immediately preceding the Change in
Control or any lesser period the officer has been employed by Canaan.  No
amounts are payable by Canaan under these agreements unless a Change in Control
occurs and the Change in Control is followed within two years by the involuntary
termination of the officer.  The amounts payable under the agreement are subject
to a limitation that the amounts paid may in no event be greater than the amount
that would be deductible by Canaan under applicable Internal Revenue Code
(golden parachute) payment limitations, after taking into consideration all
payments to the officer covered by such limitation, which would include payments
deemed to have been received due to any acceleration of vesting of stock options
or other benefits.

Compensation Decisions

          Canaan does not currently have a compensation committee.  Messrs.
Woodard and Penton participated in the decision making process with respect to
each of their compensation and the compensation of Mr. Mewbourn.

Stock Option Plan

          In January, 2000, the Board of Directors and Canaan's shareholders
adopted Canaan's 2000 Stock Option Plan (the "Option Plan").  Under the Option
Plan, Canaan may grant both incentive stock options intended to qualify under
Section 422 of the Internal Revenue Code and options which are not qualified as
incentive stock options.

          The maximum number of shares of Common Stock issuable under the Option
Plan is 500,000, subject to appropriate equitable adjustment in the event of a
reorganization, stock split, stock dividend, reclassification or other change
affecting Canaan's Common Stock. All executive officers of Canaan and other key
employees who hold positions of significant responsibility are eligible to
receive awards under the Option Plan.  The exercise price of options granted
under the Plan is not less than 100% of the fair market value of the shares on
the date of grant.  Options granted under the Plan become exercisable at such
time as the Board may determine in connection

                                     -153-
<PAGE>

with the grant of each option. In addition, the Board may at any time accelerate
the date that any option granted becomes exercisable. Certain limitations exist
on the duration, exercise price and number of shares that may be subject to or
exercised in connection with incentive stock options. The exercise price of
options may be paid in cash, in shares of Common Stock (valued at fair market
value at the date of exercise), by surrender of a portion of the option, or by a
combination of such means of payment, as may be determined by the Board of
Directors.

          In the event of any reorganization, merger, consolidation or sale of
substantially all of the assets of Canaan while options remain outstanding under
the Option Plan, the Option Plan provides for substitute options with an
appropriate number of shares or other securities of the reorganized, merged,
consolidated or acquiring corporation which were distributed to the shareholders
of Canaan.  Unless the Board of Directors expressly provides otherwise, in the
event of a Change in Control (as defined in the Option Plan) of Canaan, all
outstanding options will become immediately and fully exercisable and optionees
will be entitled to surrender, within 60 days following the Change in Control,
unexercised options or portions of options in return for cash payment equal to
the difference between the aggregate exercise price of the surrendered options
and the fair market value of the shares of Common Stock underlying the
surrendered options.

          The Board of Directors may amend or terminate the Option Plan at any
time, except that no amendment will become effective without the approval of the
shareholders except to the extent such approval may be required by applicable
law or by the rules of any securities exchange upon which the Canaan shares are
admitted to listed trading.  The Option Plan will terminate in 2010, except with
respect to awards then outstanding.

          Prior to the offering, no options have been granted by Canaan pursuant
to the Option Plan.  Upon completion of the Offering, Canaan expects to grant to
executive officers and eligible participants under the Option Plan incentive and
nonqualified stock options in amounts which will be determined at a later date.

Profit Sharing Plan

          Canaan has historically maintained a tax qualified profit sharing plan
pursuant to which Canaan makes annual discretionary contributions for the
benefit of all eligible employees based on a percentage of covered compensation.
In 1997, 1998 and 1999, Canaan accrued discretionary contributions to the plan
in the aggregate amount of $132,000, $124,000 and $132,000 respectively,
including $65,400, $63,663 and $64,033 respectively, for the account of Canaan's
named executive officers.

Certain Transactions

          In 1998 Michael S. Mewbourn, Senior Vice President and Chief Financial
Officer of Canaan, purchased 5% of the stock of Canaan and the General Partners
for an aggregate purchase price of $32,819 payable on or before November 30,
2001 with interest at the Federal Reserve discount rate.  Canaan and the General
Partners agreed to forgive such indebtedness over a three year period and to pay
an annual bonus equal to 40% of the amount of debt forgiveness, subject to Mr.
Mewbourn continuing his employment.  In 1999, $10,939 of the indebtedness was
forgiven by Canaan and the General Partners and Mr. Mewbourn received a bonus of
$6,017 of which $ 4,376 related to this arrangement.  At December 31, 1999, the
amount of the remaining indebtedness to Canaan and the General Partners was a
total of $10,939.

          Canaan Securities, of which Thomas H. Henson is sole owner and
President, receives fees from the partnerships for services in connection with
providing reports and distribution information to limited partners.  Canaan
Securities also receives fees from the general partner of each partnership for
services in connection with the sale of partnership interests in the
partnerships.  In 1999, Canaan received $89,810 in fees from the partnerships
and $185,586 in fees from the General Partners.

          Twister Gas Services L.L.C., of which Michael P. Cross is President
and a principal owner, has purchased natural gas from certain Coral partnerships
in the ordinary course of Twister's gas marketing business for more than the
past five years.  In 1999, the aggregate sales of natural gas by the Coral
partnerships to Twister was $1,529,930.  This represented 14.2% of the total
1999 sales by the Coral partnerships, and less than 2% of Twister's total 1999
purchases.


                   SECURITY OWNERSHIP OF CERTAIN BENEFICIAL
                             OWNERS AND MANAGEMENT


          The following table sets forth certain information regarding the
beneficial ownership of Canaan's Common Stock as of January 1, 2000 and the pro

Each of the partnerships is a pass-through entity for tax purposes, in which income is not
 taxed at the entity level but instead is allocated, along with losses, directly to the partners.
 The partners are taxed on income allocated to them, whether or not actual cash distributions
 are made to the partners.  On the other hand, to the extent that Canaan has any net income,
 such income will be taxed at the corporate level at the standard corporate tax rates.

Shareholders have greater control over management of Canaan than the limited partners have
over the management of the partnerships because the members of the Board of Directors of
Canaan are elected on an annual basis by the shareholders of Canaan. However, in both cases,
limited partners and shareholders must rely upon management for the prudent administration
of their investments.

The basic operating strategy of Canaan will be substantially similar to the operating
strategies of the partnerships.  However, Canaan's oil and natural gas interests will be
substantially larger and more diversified than any of the individual partnerships or all of the
partnerships taken together.  Furthermore, unlike the partnerships, Canaan has substantial
flexibility to raise equity, through the sale of common stock or preferred stock, to finance its
operations.

------------------------------------------------------------------------------------------------------
The fiduciary duty owed to shareholders of Canaan is substantially the same as the fiduciary
duty owed to the limited partners in the partnerships.   Therefore, the combination
transactions generally will not involve any reduction in the standard of care owed to
investors or any reduction in the remedies available for any breach of those duties.

With the exception of the right to participate in annual elections of directors, the voting rights
of shareholders of Canaan will be substantially the same as the voting rights of limited
partners in the partnerships; however, because the former limited partners will own a smaller
percentage interest in Canaan than they did of their respective partnerships, the former
limited partners will experience a corresponding decrease in their relative voting power once
they become shareholders of Canaan.

The ability of the shareholders of Canaan to call a special meeting of the shareholders will be
more difficult than the ability of the limited partners to call a meeting of the limited partners.

The shareholders of Canaan are subject to various anti-takeover provisions in the certificate
of incorporation and bylaws of Canaan which the limited partners did not face in the
partnership.  These anti-takeover provisions could work to delay or frustrate the assumption
of control of Canaan by a holder of a large block of common stock or the removal of
incumbent members of the Board of Directors of Canaan, even if such actions would be
beneficial to the shareholders of Canaan.

The partnership agreement provides,
however, that (i) in any such event if there is
at least one remaining General Partner, the
business of the partnership may be continued
without dissolution by a remaining General
Partner or (ii) within ninety (90) days of a
General Partner's withdrawal, all the
remaining partners may agree in writing to
continue the business of the partnership and
elect additional General Partners, if
necessary or desired.
----------------------------------------------------------------------------------------------------------------------------------
Although the partnerships provide for dissolution upon certain events, there are no unilateral rights of the limited partners to
compel a dissolution of the partnerships. As such, the right of the shareholders to compel dissolution of Canaan will be
substantially the same as the limited partners rights to compel dissolution of the partnerships.

          After the completion of the combination transactions, any
distributions or compensation paid by the partnerships will be paid to Canaan
for the benefit of all shareholders of Canaan.

                         DESCRIPTION OF CAPITAL STOCK

General

          Canaan's authorized capital stock consists of 50,000,000 shares of
common stock, $.01 par value, and 1,000,000 shares of preferred stock, $.01 par
value.

Common Stock

          The holders of common stock are entitled to one vote for each share of
common stock held  on all matters voted upon by shareholders, including the
election of directors. Subject to the rights of any then outstanding shares of
preferred stock, the holders of common stock are entitled to dividends as may be
declared in the discretion of the board of directors out of funds legally
available for the payment of dividends.  The holders of common stock are
entitled to share ratably in Canaan's net assets upon liquidation after Canaan
pays or provides for all liabilities and for any preferential liquidation rights
of any preferred stock then outstanding. The common shareholders have no
preemptive rights to purchase shares of Canaan stock.  Shares of common stock
are not subject to any redemption provisions and are not convertible into any of
our other securities.  All of the shares of common stock which we are going to
issue in the combination transactions will be fully paid and nonassessable.

                                     -169-
<PAGE>

Preferred Stock

          Our board of directors has the authority, without further action by
shareholders, to issue shares of undesignated preferred stock from time to time
in one or more series and to fix the related number of shares and the
designations, voting powers, preferences, optional and other special rights, and
restrictions or qualifications of that preferred stock.  The rights,
preferences, privileges and restrictions or qualifications of different series
of preferred stock may differ with respect to dividend rates, amounts payable on
liquidation, voting rights, conversion rights, redemption provisions, sinking
fund provisions and other matters. The issuance of preferred stock could:

          .    decrease the amount of earnings and assets available for
               distribution to holders of common stock;

          .    adversely affect the rights and powers, including voting rights,
               of holders of common stock; and

          .    have the effect of delaying , deferring or preventing a change in
               control.

Oklahoma Law and Certificate and Bylaw Provisions - Anti-Takeover Effects

          General.  Canaan's certificate and bylaws, and the OGCA include a
number of provisions which may have the effect of encouraging persons
considering unsolicited tender offers or other unilateral takeover proposals to
negotiate with Canaan's board of directors rather than pursue non-negotiated
takeover attempts.  These provisions include a classified board of directors,
advance notice requirements for shareholder proposals and director nominations,
restrictions on business combinations and stock repurchases, prohibition against
actions approved by written consent without the approval of all the
shareholders, and the adoption of the Oklahoma control share provisions.  These
certificate and bylaws provisions could work to delay or frustrate the
assumption of control of Canaan by the holder of a large block of common stock
or the removal of incumbent directors, even if such actions would be beneficial
to the shareholders as a whole.  Furthermore, these provisions may discourage or
prevent a merger, tender offer or proxy contest even if it would be favorable to
the interests of the shareholders as a whole.  The following is a more specific
description of each of these certificate and bylaws provisions:

          Classified Board of Directors.  Canaan's certificate and bylaws
contain provisions for a staggered board of directors with one-third (1/3) of
the Board standing for election each year.  The term of each director is three
years, and in each year the terms of the directors in one class will expire.
Directors may be removed only for cause and by the affirmative vote  of the
holders of a majority of the shares entitled to vote in an election of
directors.  A staggered board of directors makes it more difficult for
shareholders to change the majority of the members of the board of directors and
instead promotes continuity of existing management.

          Advance Notice Requirements for Shareholder Proposals and Director
Nominations.  Under the bylaws, a notice of intent of a shareholder to bring any
matter before a meeting of the shareholders must be made in writing and received
by our corporate secretary not more than one hundred fifty (150) days and not
less than ninety (90) days in advance of the annual meeting, or, in the event of
a special meeting of shareholders, such notice must be received by the secretary
not later than the close of the fifteenth (15th) day following the day on which
notice of the special meeting is first mailed to the shareholders.  Every notice
by a shareholder must state:

          .    The name and address of the shareholder who intends to bring up
               any matter.

          .    A representation that the shareholder is a registered holder of
               Canaan's voting stock and intends to appear in person or by proxy
               at the meeting to bring up the matter specified in the notice.

          .    With respect to notice of an intent to make a director
               nomination, a description of all understandings among the
               shareholder and each nominee and any other person, naming such
               person or persons, pursuant to which the nomination or
               nominations are to be made by the shareholder and such other
               information regarding each nominee proposed by the shareholder as
               would have been required to be included in a proxy statement
               filed pursuant to the proxy rules of the SEC had each nominee
               been nominated by the board of directors of Canaan.

          .    With respect to notice of an intent to bring up any other matter,
               a description of the matter, and any material interest of the
               shareholder in the matter.

          .    Notice of intent to make a nomination shall be accompanied by the
               written consent of each nominee to serve as a director, if
               elected.

          Business Combinations with Interested Shareholders.  Canaan's
certificate contains a provision expressly electing to be governed by Section
1090.3 of the OGCA which places restrictions on Canaan's ability to enter into
business combinations and effect stock repurchases.  Specifically, Section
1090.3 of the OGCA generally prevents an "interested shareholder" from engaging
in a "business combination" with a corporation for three years following the
date such person became an interested shareholder, unless:

          .    Prior to the time such person became an interested shareholder,
               the board of directors of the corporation approved the
               transaction in which the interested shareholder became an
               interested shareholder or approved the business combination;

                                     -171-
<PAGE>

          .    Upon consummation of the transaction that resulted in the
               interested shareholder becoming an interested shareholder, the
               interested shareholder owns at least 85% of the voting stock of
               the corporation outstanding at the time the transaction
               commenced, excluding stock held by directors who are also
               officers of the corporation and stock held by some employee stock
               plans; or

          .    On or subsequent to the time of the transaction in which such
               person became an interested shareholder, the business combination
               is approved by the board of directors of the corporation and
               authorized at a meeting of shareholders by the affirmative vote
               of the holders of two-thirds (2/3) of the outstanding voting
               stock of the corporation not owned by the interested shareholder.

The statute defines a "Business Combination" to include:

          .    any merger or consolidation involving the corporation and an
               interested shareholder;

          .    any sale, transfer, pledge or other disposition involving an
               interested shareholder of ten percent (10%) or more of the assets
               of the corporation;

          .    subject to exceptions, any transaction which results in the
               issuance or transfer by the corporation of any stock of the
               corporation to an interested shareholder;

          .    any transaction involving the corporation which has the effect of
               increasing the proportionate share of the stock of any class or
               series of the corporation beneficially owned by the interested
               shareholder;

          .    the receipt by an interested shareholder of any loans,
               guarantees, pledges or other financial benefits provided by or
               through the corporation; or

          .    any share acquisition by the interested shareholder pursuant to
               Section 1090.1 of the OGCA.

          In addition, the statutes define "interested shareholder" as any
entity or person beneficially owning fifteen percent (15%) or more of the
outstanding voting stock of the corporation and any entity or person affiliated
with or controlling or controlled by such entity or person.

                                     -172-

          Prohibition Against Actions by Written Consent.  Canaan's certificate
provides for any action required by the OGCA to be taken or otherwise permitted
to be taken at any annual or special meeting of shareholders of the corporation
may be taken without a meeting, without prior notice and without a vote, only if
a consent or consents in writing, setting forth the action taken, shall be
signed by the holders of all outstanding stock entitled to vote thereon.  This
provision effectively prevents any actions without a meeting, notice and a vote
of our shareholders.

          Control Share Provisions.  Canaan's certificate specifically provides
that we will be subject to the Oklahoma control share acquisition statute
("Oklahoma Control Share Statute"), codified at Sections 1145-1155 of the OGCA.
Section 1145 of the OGCA defines "control shares" as those issued and
outstanding shares of an "issuing public corporation" that, in the absence of
the Oklahoma Control Share Statute, would have voting power, when added to all
the other shares of the issuing public corporation which are owned, directly or
beneficially, by an acquiring person or over which the acquiring person has the
ability to exercise voting power, that would entitle the acquiring person,
immediately after the acquisition of the shares to exercise, or direct the
exercise of, the voting power of the issuing public corporation in the election
of directors within any of the following ranges of voting power:


     .    one-fifth (1/5) or more but less than one-third (1/3) of all voting
          power;


     .    one-third (1/3) or more but less than a majority of all voting power;
          or


     .    a majority of all voting power.

          A "control share acquisition" means the acquisition by any person of
ownership of, or the power to direct the exercise of voting power with respect
to, "control shares."  After a control share acquisition occurs, the acquiring
person is subject to limitations on the ability to vote such control shares.
Specifically, Section 1149 of the OGCA provides in pertinent part that under
most control share acquisition scenarios, "the voting power of control shares
having voting power of one-fifth (1/5) or more of all voting power is reduced to
zero unless the shareholders of the issuing public corporation approve a
resolution . . . according the shares the same voting rights as they had before
they became control shares."  Section 1153 of the OGCA provides the procedures
for obtaining shareholder consent of a resolution of an "acquiring person" to
determine the voting rights to be accorded the shares acquired or to be acquired
in the control share acquisition.  Accordingly, "to be approved, the resolution
shall receive the affirmative votes of a majority of all voting power, excluding
all interested shares."  Therefore, Canaan's adoption of the Oklahoma Control
Share Statute makes it more difficult for a person acquiring "control shares" to
exercise his voting rights as a shareholder.

          General Result of Anti-Takeover Measures.  By discouraging takeover
attempts, these provisions may have the incidental effect of inhibiting the
temporary fluctuations of the market price of Canaan's common stock or other
securities which may result from actual or rumored takeover attempts.  In
addition, these provisions could limit or reduce the price that investors might
be willing to pay for our shares and may limit the ability of Canaan's
shareholders to receive premium prices for their shares which an acquiring party
might be willing to pay in connection with the acquisition of control of Canaan.

                          FORWARD LOOKING STATEMENTS

          All statements made in this document and accompanying supplements
other than purely historical information are "forward looking statements" within
the meaning of the federal securities laws.  These statements reflect
expectations and are based on historical operating trends, proved reserve
positions and other currently available information.  Forward looking statements
include statements regarding future plans and objectives, exploration and
development budgets and number and location of planned wells and statements
regarding the quality of our properties and potential reserve and production
levels.  This statement may be preceded or followed by or otherwise include the
words "believes", "expects", "anticipates", "intends", "plans", "estimates",
"projects" or similar expressions or statements that events "will" or "may"
occur.  These statements assume that no significant changes will occur in the
operating environment for oil and gas properties and that there will be no
material acquisitions or divestitures except as otherwise described.

          The forward looking statements are subject to all the risks and
uncertainties incident to the combination transactions and acquisition,
exploration, development, marketing of oil and gas reserves, including the risks
described under "Risk Factors."  Canaan may also make material acquisitions or
divestitures or enter into financing transactions.  None of these events can be
predicted with certainty or not taken into consideration in the forward looking
statements.

          For all of these reasons, actual results may vary materially from the
forward looking statements and there is no assurance that the assumptions used
are necessarily the most likely.  Canaan will not update any forward looking
statements to reflect events or circumstances occurring after the date the
statement is made except as may be required by federal securities laws.

tangible or intangible, necessary to complete a well and bring it into
production, including installation of service equipment, tanks and other
materials necessary to enable the well to deliver production.

          Developed Acreage.  "Developed Acreage" means the number of acres
          -----------------
which are allocated or assignable to producing wells or wells capable of
production.

          Development Location.  "Development Location" means a location on

          ------
taxes, depreciation, depletion and amortization and impairment.  We believe that
EBITDA is a financial measure commonly used in the oil and gas industry as an
indicator of a company's ability to service and incur debt.  However, EBITDA
should not be considered in isolation or as a substitute for net income, cash
flows provided by operating activities or other data prepared in accordance with
generally accepted accounting principles, or as a measure of a company's

Exchange Reserves consist of  proved reserves as defined by the Society of
Petroleum Engineers based on the oil and gas prices specified by Canaan and the
General Partners for purposes of the calculation of Exchange Reserves.  Because
the prices specified by Canaan and the General Partners for the calculation of
Exchange Reserves do not use prices in effect as of September 30, 1999, the
Exchange Reserves do not constitute Proved Reserves as defined by the Securities
and Exchange Commission.

          Exchange Value.  "Exchange Value" means the value assigned to the
          --------------
Combining Entities and the respective owners thereof for purposes of the

and production of proved undeveloped reserves that lie within an area bounded by
producing wells.

          Lease Operating Expense.  "Lease Operating Expense" means all direct
          -----------------------
costs associated with and necessary to operate a producing property.

          Lifting Costs.  "Lifting Costs" means the expenses of lifting oil from
          -------------
a producing formation to the surface, consisting of the costs incurred to
operate and maintain wells and related equipment and facilities, including labor
costs, repair and maintenance, supplies, insurance, production, severance and
windfall profit taxes.

          Overriding Royalty Interest.  "Overriding Royalty Interest" means an
          ---------------------------
interest in an oil and gas property entitling the owner to a share of oil and
gas production free of well or production costs.

          Present Value.  "Present Value," when used with respect to oil and gas
          -------------
reserves, means the estimated future gross revenue to be generated from the
production of proved reserves, net of estimated production, future development
costs, future income tax expense and future abandonment costs, using prices and
costs in effect as of the date of the report or estimate, without giving effect
to non-property related expenses such as general and administrative expenses and
debt service or to deprecation, depletion and amortization, discounted using an
annual discount rate of 10%.  Present Value is the same as the "Standard Measure
of Discounted Future Net Cash Flows" as prescribed by Statement of Financial
Accounting Standards No. 69 promulgated by the Financial Accounting Standards
Board.

          Productive Well.  "Productive Well" means a well that is producing oil
          ---------------
or gas or that is capable of production.

          Proved Developed Reserves.  "Proved Developed Reserves" means proved
          -------------------------
reserves that are expected to be recovered through existing wells with existing
equipment and operating methods.  Additional oil and gas expected to be obtained
through the application of fluid injection or other improved recovery techniques
for supplementing the natural forces and mechanisms of primary recovery are
included as proved developed reserves only after testing by pilot project or
after the operation of an installed program as confirmed through production
response that increased recovery will be achieved.

          Proved Reserves.  "Proved Reserves" means the estimated quantities of
          ---------------
crude oil, natural gas and natural gas liquids which geological and engineering
data demonstrate with reasonable certainty to be recoverable in future years
from known reservoirs under existing economic and operating conditions; i.e.,
prices and costs as of the date the estimate is made. Prices include
consideration of changes in existing prices provided only by contractual
arrangements, but not on escalations based upon future conditions.

          Proved Undeveloped Reserves.  "Proved Undeveloped Reserves" means
          ---------------------------
proved reserves that are expected to be recovered from new wells on undrilled
acreage, or from existing wells where a relatively major expenditure is required
for recompletion.  Reserves on undrilled acreage are limited to those drilling
units offsetting productive units that are reasonably certain of production when
drilled.  Proved reserves for other undrilled units can be claimed only where it
can be demonstrated with certainty that there is continuity of production from
the existing productive formation.  Under no circumstances do estimates for
proved undeveloped reserves be attributable to any acreage for which an
application of fluid injection or other improved recovery techniques is
contemplated, unless such techniques have been proved effective by actual tests
in the area and in the same reservoir.

                                     -180-

          Recompletion.  "Recompletion" means the completion for production of
          ------------
an existing wellbore in another formation from that in which the well has
previously been completed.

          Reserve Value.  "Reserve Value" means the estimated future gross
          -------------
revenue to be generated from production of Exchange Reserves, net of estimated
production, future development costs and future abandonment costs, using prices
as specified by Canaan and the General Partners.  The Reserve Value is
calculated for purposes of the calculation of the Exchange Value and is not the
same as the term present value.

          Royalty Interest.  "Royalty Interest" mean an interest in an oil and
          ----------------
gas property entitling the owner to a share of oil and gas production, or the
proceeds of the sale thereof, free of the costs of production.

          3-D Seismic.  "3-D Seismic" means the method by which a three
          -----------
dimensional image of the earth's substance is created through the interpretation
of aerially collected seismic data.  3-D surveys allow for a more detailed
understanding of the subsurface than do conventional surveys and contribute
significantly to field appraisal, development and production.

          Undeveloped Acreage.  "Undeveloped Acreage" means lease acreage on
          -------------------
which wells have not been drilled or completed to a point that would permit the
production of commercial quantities of oil and gas regardless of whether such
acreage contains proved reserves.

          Working Interest.  "Working Interest" means the operating interest
          ----------------
which gives the owner the right to drill, produce and conduct operating
activities on the property and a share of production.

                          INDEPENDENT AUDITORS' REPORT



The Board of Directors and Stockholders
Canaan Energy Corporation:

We have audited the accompanying balance sheets of Canaan Energy Corporation, as
of December 31, 1998 and 1999, and the related statements of operations,
stockholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1999.  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 Canaan Energy Corporation, as
of December 31, 1998 and 1999, and the results of its operations and its cash
flows for each of the years in the three-year period ended December 31, 1999, in
conformity with generally accepted accounting principles.

                         Notes to Financial Statements

                       December 31, 1997, 1998 and 1999
           (Information insofar as it relates to March 31, 2000 and
         the three months ended March 31, 1999 and 2000 is unaudited)


1.   Organization and Basis of Presentation

     Canaan Energy Corporation (Canaan) is engaged primarily in the acquisition,
development and production of oil and natural gas properties. Canaan serves as
operator for approximately 107 producing oil and natural gas wells located in
Oklahoma.

     Canaan also manages eight oil and natural gas limited partnerships (the
Coral Limited Partnerships) on behalf of Coral Reserves, Inc. and Coral Reserves
Energy Corporation, the general partners of the Coral Limited Partnerships (the
General Partners). Canaan and the General Partners have the same ownership.

     Canaan, the Coral Limited Partnerships, the General Partners and Canaan
Securities, Inc. (CSI), an unaffiliated broker/dealer which has previously
participated in marketing of the limited partnership interests, are in the
process of merging (subject to the approval of all parties), whereby the Coral
Limited Partnerships, the General Partners and CSI will merge with and into
Canaan for shares of Canaan's common stock. The merger with the Coral Limited
Partnerships and the General Partners is expected to be accounted for as a
reorganization of interests in a manner similar to a pooling of interests and
the merger with CSI is expected to be accounted for as a purchase. Additionally,
on February 15, 1999 Canaan entered into an agreement and plan of merger with
Indian Oil Company (Indian), an unaffiliated oil and natural gas company. Under
the agreement, Indian will merge with and into Canaan for shares of Canaan's
common stock in a business combination to be accounted for as a purchase. The
mergers are anticipated to be completed in July 2000.

     On January 3, 2000, Coral Reserves Group, Ltd. changed its name to Canaan
Energy Corporation but continues to conduct business as Coral Reserves Group,
Ltd.

     Accounting policies employed by Canaan reflect industry practices and
conform to generally accepted accounting principles. The more significant of
such policies are discussed below.

     In the opinion of management, the accompanying unaudited financial
statements as of March 31, 2000 and for the three months ended March 31, 1999
and 2000, reflect all adjustments (which were normal and recurring) which, in
the opinion of management, are necessary for a fair statement of the financial
position and results of operations of the interim periods presented.


2.   Summary of Significant Accounting Policies

     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 the
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 amounts could differ from those estimates.

                         Notes to Financial Statements
                                  (Continued)


     Cash and Cash Equivalents

     Canaan considers all highly liquid investments with a maturity of three
months or less at time of purchase to be cash equivalents. Cash equivalents
consist of overnight investments in money market funds.

     Fair Value of Financial Instruments

     Canaan's financial instruments consist of cash and cash equivalents,
accounts receivable, accounts payable, accrued expenses, other liabilities and
oil and natural gas price swap contracts. Fair value of nonderivative financial
instruments approximates carrying value due to the short-term nature of the
instruments. See "Hedging Activities" policy note for estimated fair values of
the price swap contracts.

     Property and Equipment

     Canaan follows the full cost method of accounting for its oil and natural
gas properties. Accordingly, all costs incidental to the acquisition,
exploration, and development of oil and natural gas properties, including costs
of undeveloped leasehold, dry holes and leasehold equipment, are capitalized.
Net capitalized costs (capitalized costs less accumulated amortization and
deferred income taxes) are limited to the estimated after-tax future net
revenues using period-end pricing, discounted at 10% per annum, from proved oil,
natural gas and natural gas liquids reserves plus the lower of cost or estimated
fair value of undeveloped properties subject to amortization. Canaan subjects
all costs of undeveloped properties to amortization as such costs are
insignificant. Capitalized costs less accumulated amortization plus estimated
future development cost of proved undeveloped reserves are amortized by an
equivalent unit-of-production method, converting natural gas to oil at the ratio
approximating their relative energy content of one barrel ("Bbl") of oil to six
thousand cubic feet ("Mcf") of natural gas. No gain or loss is recognized upon
disposal of oil and natural gas properties unless such dispositions
significantly alter the relationship between capitalized costs and proved oil
and natural gas reserves.

     Depreciation and amortization of other equipment are provided using the
straight-line method based on estimated useful lives of the related assets,
which range from 3 to 7 years.

     Canaan accounts for its non-oil and natural gas long-lived assets in
accordance with the provisions of Statement of Financial Accounting Standards
(SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets and Assets
to be Disposed Of". SFAS No. 121 requires that long-lived assets and
identifiable intangibles be reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future undiscounted net cash
flows expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at the lower of the carrying amount or fair value less
cost to sell.

     Other Assets

     Other assets as of December 31, 1999 and March 31, 2000, represent legal,
accounting and engineering costs incurred in connection with Canaan's proposed
merger with the Coral Limited Partnerships, the General Partners, Indian and
CSI, discussed above. Costs incurred in connection with the proposed merger of
the Coral Limited Partnerships and the General Partners are deferred as incurred
and will be

                                  (Continued)


expensed when the merger is completed or terminated since the transactions are
being accounted for as reorganization of interests under common control in a
manner similar to a pooling of interests. Costs incurred and deferred in
connection with the proposed merger of the Coral Limited Partnerships and the
General Partners approximated $258,000 and $526,000 for the year ended December
31, 1999 and the three months ended March 31, 2000, respectively. Costs incurred
in connection with the acquisitions of Indian and CSI are being deferred and
will be included in the purchase price upon completion of the acquisitions or
will be expensed if the transactions are terminated.

     Revenue and Royalty Distributions Payable

     For certain oil and natural gas properties, Canaan receives production
proceeds, from the purchaser and further distributes such amounts to other
revenue and royalty owners. Production proceeds applicable to other revenue and
royalty owners are reflected as revenue and royalty distributions payable in the
accompanying balance sheets. Canaan accrues revenue for only its net interest in
its oil and natural gas properties.

     Hedging Activities

     Canaan periodically enters into oil and natural gas price swap agreements
to manage its exposure to oil and natural gas price volatility. These contracts
have no cash requirements at inception and are with counterparties that Canaan
believes have minimal credit risks. The oil and natural gas reference prices
upon which the price hedging instruments are based reflect various market
indices that have a high degree of historical correlation with actual prices
received by Canaan.

     Canaan accounts for it's hedging contracts using the deferral method of
accounting. Under this method, realized gains and losses from Canaan's price
risk management activities are recognized in oil and natural gas revenues when
the associated production occurs and the resulting cash flows are reported as
cash flows from operating activities. In the event of a loss of correlation
between changes in oil and natural gas reference prices under a hedging contract
and actual oil and natural gas prices, a gain or loss is recognized currently to
the extent the hedging contract has not offset changes in actual oil and natural
gas prices.

     Canaan was not a party to any hedging contracts as of December 31, 1998. On
September 24, 1999, Canaan, as a participating party with the Coral Limited
Partnerships, entered into a natural gas price swap covering 1,500,000 cubic
feet of monthly production, or approximately 30% of its natural gas production
beginning October 1999 through September 2000. The price to be received for this
production is $2.60 per Mcf, while Canaan will pay the counterparty a floating
index price. On November 18, 1999, Canaan as a participating party with the
Coral Limited Partnerships, entered into an oil price swap covering 100 barrels
of monthly oil production or approximately 70% of its oil production beginning
January 2000 through December 2000. The price to be received for this production
is $22.00 per barrel, while Canaan will pay the counterparty a floating index
price.

     In April 2000, Canaan, as a participating party with the Coral Limited
Partners, entered into an additional natural gas price swap covering 1,500,000
cubic feet of monthly production or approximately 30% of its natural gas
production beginning June 2000 through May 2001. The price to be received for
this production is $2.97 per Mcf, while Canaan will pay the counterparty a
floating index price.

                           CANAAN ENERGY CORPORATION

                         Notes to Financial Statements
                                  (Continued)

     The fair value of Canaan's natural gas and oil price hedging contracts
approximated $4,000 and $(6,000) at December 31, 1999 and March 31, 2000,
respectively. This asset (liability) represents the estimated amount Canaan
would receive (pay) to cancel the contracts or transfer them to other parties.
No deferred hedging gains or losses were recorded as of December 31, 1999 or
March 31, 2000.

     Revenue Recognition and Natural Gas Balancing

     Oil and natural gas sales are recognized in the month in which the oil and
natural gas reserves are produced and sold by Canaan. Salt water disposal
service revenue and production engineering services revenues are recognized
after the services are provided at daily rates.

     During the course of normal operations, Canaan and other joint interest
owners of natural gas reservoirs will take more or less than their respective
ownership share of the natural gas volumes produced. These volumetric imbalances
are monitored over the lives of the wells' production capability. If an
imbalance exists at the time the wells' reserves are depleted, cash settlements
are made among the joint interest owners under a variety of arrangements. Canaan
follows the sales method of accounting for natural gas imbalances. A liability
is recorded only if Canaan's excess takes of natural gas volumes exceed its
estimated remaining recoverable reserves. No receivables are recorded for those
wells where Canaan has taken less than its ownership share of natural gas
production. Canaan's production imbalance position in terms of volumes and value
was not significant as of December 31, 1998 and 1999 and March 31, 2000.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
production levels from an existing completion interval, along with production
related taxes are expensed as incurred.

     Major Purchasers

     Canaan markets its oil and natural gas production to numerous purchasers
under a variety of contracts. Three purchasers accounted for 58%, four
purchasers accounted for 64% and three purchasers accounted for 66% of Canaan's
1997, 1998 and 1999 oil and natural gas revenues, respectively. Canaan had no
other purchasers that accounted for greater than 10% of its oil and natural gas
revenues. Canaan does not believe that the loss of any single customer would
have a material effect on the results of its operations.

     General and Administrative Expenses

     General and administrative expenses are reported net of amounts allocated
to working interests of the oil and natural gas properties operated by Canaan,
and net of amounts capitalized pursuant to the full cost method of accounting.
No general and administrative costs were capitalized for the years ended
December 31, 1997, 1998 and 1999 or the three months ended March 31, 1999 and
2000, due to nominal exploration and development activities of Canaan.

     General and administrative costs recovered through allocation to other
working interest owners approximated $416,000, $538,000, $643,000, $156,000 and
$166,000 for the years ended December 31, 1997, 1998 and 1999 and the three
months ended March 31, 1999 and 2000, respectively.

                                  (Continued)


     Income Taxes

     Canaan accounts for income taxes using the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized at the enacted tax rates for the future tax consequences attributable
to differences between the financial statement carrying amounts of existing
assets and liabilities and the respective tax bases and tax operating losses and
tax credit carryforwards. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

     Earnings Per Share

     Basic earnings per share data is computed by dividing net earnings
attributable to common shareholders by the weighted average number of common
shares outstanding during the period. Canaan has no other securities that would
dilute its basic earnings per share.

     Comprehensive Income

     SFAS No. 130, "Reporting Comprehensive Income," establishes standards for
reporting and display of "comprehensive income" and its components in a set of
financial statements. It requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. Canaan had no items of comprehensive income as
defined by SFAS No. 130 not included in the accompanying statements of
operations; therefore, statements of comprehensive income have not been
presented in the accompanying financial statements.


3.   Property Acquisitions

     In November 1997, Canaan acquired oil and natural gas producing properties
located in Oklahoma from Boswell Energy Corp. (Boswell) for $16,000. Estimated
proved reserves acquired in the Boswell acquisition approximated 31,000 Mcf of
natural gas equivalent (unaudited). As a result of the acquisition, Canaan
assumed operations of 15 of the producing oil and natural gas properties.

     In December 1998, Canaan acquired oil and natural gas producing properties
located in Oklahoma from Marathon Oil Co. (Marathon) for $18,000. Estimated
proved reserves acquired in the Marathon acquisition approximated 24,000 Mcf of
natural gas equivalent (unaudited). As a result of the acquisition, Canaan
assumed operations of 16 of the producing oil and natural gas properties.

     The acquired properties described above were accounted for by the purchase
method and accordingly, operations have been included in the financial
statements from the date of the respective acquisitions.

The plan allows employees to make voluntary deferred contributions subject to
Internal Revenue Code limits. Benefits payable under the plan are limited to the
amount of plan assets allocable to the account of each plan participant. Canaan
retains the right to modify, amend or terminate the plan at any time. Canaan
recorded $132,000, $124,000, $126,000, $27,000 and $27,000 of expenses related
to discretionary contributions to the plan for the years ended December 31,
1997, 1998 and 1999 and the three months ended March 31, 1999 and 2000,
respectively. Such costs were accrued by Canaan during the year and funded in
the following year.

     Canaan leases office space and equipment under operating leases expiring
over the next three years. Future minimum lease payments under non-cancelable
operating leases having remaining terms in excess of one year as of December 31,

of the promissory note equaled the fair value of the shares issued. The note
earns interest at the annual rate equal to the discount rate charged by the New
York Federal Reserve Bank, redetermined semi-annually, and is secured by the
common stock. The note matures in November 2001; however, it allows Canaan to
forgive the note as services are provided by the officer over the term of the
note. Canaan forgave approximately $7,000 of the note in 1998 and 1999 and
approximately $2,000 for the three months ended March 31, 2000. The note is
reflected in the accompanying balance sheets and statements of stockholders'
equity as a stock subscription receivable. Compensation

     Results of Operations for Oil and Natural Gas Activities

     Below is a summary of results of operations for oil and natural gas
producing activities. The results do not include any allocation of Canaan's
general corporate overhead and, therefore, are not necessarily indicative of the
contribution to net earnings of its oil and natural gas operations. Income tax
expense has been calculated by applying statutory income tax rates to oil and
natural gas sales after deducting costs, including depreciation and amortization
and considering permanent differences, tax credits and allowances related to oil
and gas producing activities.

     Quantities of Oil and Natural Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
oil and natural gas and reserves for each of the years in the three year period
ended December 31, 1999. Canaan's proved reserves at December 31, 1998 and 1999
were calculated by the independent petroleum consultants of Netherland, Sewell &
Associates, Inc. Canaan cautions that there are many uncertainties inherent in
estimating reserve quantities, and in projecting future production rates and the
timing of future development cost expenditures. In addition, reserve estimates
of new discoveries are more imprecise than those of properties with a production
history. Accordingly, these estimates are subject to change as additional
information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
oil, condensate, natural gas and natural liquids that geological and engineering
data demonstrate with reasonable certainty to be recoverable in future years
from known reservoirs under existing economic conditions. Proved developed oil
and natural gas reserves are those reserves expected to be recovered through
existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
reserves of crude oil, including condensate and natural gas liquids, and natural
gas, as well as the changes in proved reserves during the periods indicated, are
set forth in the tables below. All reserves are located in the United States.

     Canaan prepared the estimated reserves as of December 31, 1996 and 1997
based on geological and engineering evaluations performed as of December 31,
1998. The reserve estimates as of the prior year-end dates were derived by
analyzing actual historical production amounts and by adjusting the reserves
attributable to wells acquired or disposed of during the relevant periods. In
addition, in deriving the estimates as of December 31, 1996 and 1997, Canaan
used production costs based on actual costs incurred during the years and actual
oil and natural gas prices received on December 31, 1996 and 1997. Canaan has
estimated its reserves as of December 31, 1996 and 1997 in this manner because
the actual information necessary to calculate estimated proved reserves and
related information in accordance with guidelines of the SEC as of each date is
not available. Because the reserve estimates as of December 31, 1998 are based
on additional information gained from the result of drilling, testing and
production subsequent to the dates of the estimated reserves, the reserve
estimates as of December 31, 1996 and 1997 are not necessarily reflective of
quantities that might have been estimated based on information available as of
such dates had estimates in accordance with SEC guidelines been made at such
dates. Management believes that, because of the methodology used, the reserve
information presented is more reflective of actual reserve quantities than
estimates that might have been generated as of such dates.

estimating the expenditures to be incurred in developing and producing proved
oil and gas reserves at the end of each year, based on respective year-end costs
and assuming continuation of existing economic conditions.

         Future income tax expenses are computed by applying the appropriate
statutory rates to the future pre-tax net cash flows relating to proved
reserves, net of the tax basis of the properties involved giving effect to
permanent differences, tax credits and allowances relating to proved oil and gas
reserves.

         Principal changes in the standardized measure of discounted future net
cash flows attributable to Canaan's proved reserves are as follows:

The Board of Directors and Stockholders
Indian Oil Company:

We have audited the accompanying balance sheets of Indian Oil Company as of
December 31, 1998 and 1999, and the related statements of operations,
stockholders' equity (deficit), and cash flows for each of the years in the
three-year period ended December 31, 1999. 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 Indian Oil Company as of
December 31, 1998 and 1999, and the results of its operations and its cash flows
for each of the years in the three-year period ended December 31, 1999, in

                              INDIAN OIL COMPANY

                         Notes to Financial Statements

                       December 31, 1997, 1998 and 1999
           (Information insofar as it relates to March 31, 2000 and
         the three months ended March 31, 1999 and 2000 is unaudited)

1.   Organization and Basis of Presentation

     Indian Oil Company (Indian) is engaged in the exploration, development and
production of natural gas, and to a lesser extent, crude oil. Indian's oil and
natural gas operations are concentrated in Oklahoma and western Arkansas, and to
a lesser extent in Texas, Kansas and Louisiana.

     On February 15, 1999, Indian entered into an Agreement and Plan of Merger
with Canaan Energy Corporation (Canaan) and its affiliates (the Coral Group).
Under the plan, within 18 months, Indian will merge with and into Canaan and all
of its issued and outstanding shares will be converted into shares of Canaan.
During the interim period prior to the merger, Indian authorized Canaan to
manage Indian on a day-to-day basis.

     In the opinion of management, the accompanying unaudited financial
statements as of March 31, 2000 and for the three months ended March 31 1999 and
2000, reflect all adjustments (which were normal and recurring) which, in the
opinion of management, are necessary for a fair statement of the financial
position and results of operations of the interim periods presented.


2.   Summary of  Significant Accounting Policies

Use of Estimates

     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates, judgments
and assumptions that affect the reported amounts of assets and liabilities as of
the date of the financial statements and revenues and expenses during the
reporting periods. Actual results could differ from those estimates.

Cash and Cash Equivalents

     Indian considers all highly liquid investments with maturity of three
months or less at time of purchase to be cash equivalents. Cash equivalents
consist of overnight investments in money market funds.

Property and Equipment

     Indian follows the full cost method of accounting for its oil and natural
gas properties. Accordingly, all costs associated with acquisition, exploration
and development of oil and natural gas properties are capitalized, including
nonproductive costs and overhead costs directly identified with acquisition,
exploration and development activities. Indian capitalized $240,000, $200,000,
$60,000 and $60,000 for the years ended December 31, 1997, 1998 and 1999, and
the three months ended March 31, 2000, respectively, of overhead costs related
to acquisition, exploration and development activities. No costs were
capitalized for the three months ended March 31, 1999 due to nominal
acquisition, exploration and development activities of Indian during the period.
Net capitalized costs (capitalized costs less accumulated amortization and
deferred income

                                      F-27
<PAGE>

                              INDIAN OIL COMPANY

                         Notes to Financial Statements
                                  (Continued)

taxes) are limited to the estimated after-tax future net revenues based on
period end pricing, discounted at 10% per year, from proved oil and natural gas
reserves plus the lower of cost or estimated fair value of unproved properties
subject to amortization. Indian compares the carrying value of its oil and
natural gas properties to the calculated limitation at each period end.
Capitalized costs less accumulated amortization plus estimated future
development costs are amortized by an equivalent units-of-production method,
converting barrels to natural gas at the ratio approximating their relative
energy content of one barrel of oil to six Mcf of natural gas. No gain or loss
is recognized upon the disposal of oil and natural gas properties, unless such
dispositions significantly alter the relationship between capitalized costs and
proved oil and natural gas reserves.

     Oil and natural gas properties not subject to amortization consist of the
cost of undeveloped leaseholds which have not been assigned proved reserves.
These unproven properties are evaluated, on an individual basis, by management
for impairment, with the impairment provision included in the cost of oil and
natural gas properties subject to amortization. Factors considered by management
in its impairment assessment include drilling results by Indian and other
operators, the terms of oil and natural gas leases not held by production, and
available funds for exploration and development.

     Depreciation and amortization of other property and equipment, including
leasehold improvements, are provided using the straight-line method based on
estimated useful lives of the related assets, which range from 3 to 7 years.

     Indian accounts for its non-oil and natural gas long-lived assets in
accordance with the provisions of Statement of Financial Accounting Standards
(SFAS) No. 121, "Accounting for the Impairment of Long-Lived Assets and Assets
to be Disposed Of." SFAS No. 121 requires that long-lived assets and
identifiable intangibles be reviewed for impairment whenever events or changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Recoverability of assets to be held and used is measured by a
comparison of the carrying amount of an asset to future undiscounted cash flows
expected to be generated by the asset. If such assets are considered to be
impaired, the impairment to be recognized is measured by the amount by which the
carrying amount of the assets exceeds the fair value of the assets. Assets to be
disposed of are reported at the lower of the carrying amount or fair value less
cost to sell.

Debt Issuance Costs

     Indian capitalized $279,000 of costs related to the issuance of debt in
December 1997. Included in the amount capitalized was $125,000 of costs paid to
certain stockholders and an affiliated company for their guaranty of a portion
of the debt and for modifications to the terms of the subordinated 1998 notes
payable to stockholders. Also included in the amount capitalized was $45,000
paid to the president of Indian for his role as legal counsel in the preparation
and review of the related debt agreements. In 1999, Indian capitalized $120,000
of costs related to the modification of its debt agreements. Amortization of
debt issuance costs is recognized as interest expense over the repayment terms
of the related debt using the straight-line method, which does not materially
differ from the use of the effective interest method.

     Accumulated amortization of debt issuance costs as of December 31, 1998 and
1999, and March 31, 2000, approximated $145,000, $379,000 and $399,000,
respectively.

                              INDIAN OIL COMPANY

                         Notes to Financial Statements
                                  (Continued)

Revenue and Royalty Distributions Payable

     For certain oil and natural gas properties, Indian receives production
proceeds from the purchaser and further distributes such amounts to other
revenue and royalty owners. Production proceeds applicable to other revenue and
royalty owners are reflected as revenue and royalty distributions payable in the
accompanying balance sheets. Indian accrues revenue for only its net revenue
interest in oil and natural gas properties.

Hedging Activities

     Indian periodically enters into oil and natural gas price swap agreements
to manage its exposure to oil and natural gas price volatility. These contracts
have no cash requirements at inception and are with counterparties that Indian
believes have minimal credit risks. The oil and natural gas reference prices
upon which the price hedging contracts are based reflect various market indices
that have a high degree of historical correlation with actual prices received by
Indian.

     Indian accounts for its hedging contracts using the deferral method of
accounting. Under this method, realized gains and losses from Indian's price
risk management activities are recognized in oil and natural gas revenues when
the associated production occurs and the resulting cash flows are reported as
cash flows from operating activities. In the event of a loss of correlation
between changes in oil and natural gas reference prices under a hedging contract
and actual oil and natural gas prices, a gain or loss is recognized currently to
the extent the hedging contract has not offset changes in actual oil and natural
gas prices.

     Indian was not a party to any hedging contracts as of December 31, 1998. At
December 31, 1999, Indian was a party to two natural gas price-hedging contracts
covering 300 million cubic feet of monthly natural gas production. One price
hedging contract covering 50 million cubic feet of monthly natural gas
production terminates on April 1, 2000. The remaining hedge contract terminates
on October 1, 2000. The weighted average price to be received for the hedged
production is $2.14 per Mcf, while Indian will pay the counterparty a floating
index price.

     On November 18, 1999, Indian as a participating party with the Coral Group,
entered into an oil price swap covering 2,000 barrels of its monthly oil
production beginning January 2000 through December 2000. The price to be
received for this production is $22.00 per barrel, while Indian will pay the
counterparty a floating index price.

     The fair value of Indian's natural gas and oil price hedging contract
liability approximated $208,000 and $1,348,000 at December 31, 1999 and March
31, 2000, respectively. This liability represents the estimated amount Indian
would have to pay to cancel the contracts or transfer them to other parties. No
deferred hedging gains or losses were recorded as of December 31, 1998, 1999 or
March 31, 2000, respectively.

Natural Gas Balancing

     During the course of normal operation, Indian and other joint interest
owners of natural gas reservoirs will take more or less than their respective
ownership share of the natural gas volumes produced. These volumetric imbalances
are monitored over the lives of the wells' production capability. If an
imbalance exists at the time the wells' reserves are depleted, cash settlements
are made among the joint interest owners under a variety of arrangements.

                                      F-29
<PAGE>

                              INDIAN OIL COMPANY

                         Notes to Financial Statements
                                  (Continued)

     Indian follows the sales method of accounting for natural gas imbalances. A
liability is recorded only if Indian's excess takes of natural gas volumes
exceed its estimated remaining recoverable reserves. No receivables are recorded
for those wells where Indian has taken less that its ownership share of natural
gas production. As of December 31, 1998 and 1999 and March 31, 2000, Indian had
a net underproduced imbalance position of 822 million, 834 million and 366
million cubic feet of natural gas, respectively. The fair value of the net
underproduced imbalance position as of December 31, 1998, 1999 and March 31,
2000, approximated $1,600,000, $1,790,000 and $950,000, respectively, using
natural gas prices at the end of the respective periods.

General and Administrative Expenses

     General and administrative expenses are reported net of amounts allocated
to working interest owners of the oil and natural gas properties operated by
Indian and net of amounts capitalized pursuant to the full cost method of
accounting.

Production Costs

     Lease operating costs, including costs incurred to maintain or increase
production levels from existing completion intervals, along with production
related taxes are expensed as incurred.

Major Purchasers

     Indian markets its oil and gas production to numerous purchasers under a
variety of short-term contracts. During 1997, 1998 and 1999, Indian's two, three
and one largest purchasers accounted for 40%, 38% and 28%, respectively, of its
oil and natural gas revenues. Indian had no other purchasers that accounted for
greater than 10% of its oil and natural gas revenues. Indian does not believe
that the loss of any single customer would have a material effect on the results
of its operations.

Income Taxes

     Indian accounts for income taxes using the asset and liability method.
Under the asset and liability method, deferred tax assets and liabilities are
recognized at the enacted tax rates for the future tax consequences attributable
to differences between the financial statement carrying amounts of existing
assets and liabilities and the respective tax bases and tax operating losses and
tax credit carryforwards. The effect on deferred tax assets and liabilities of a
change in tax rates is recognized in income in the period that includes the
enactment date.

Comprehensive Income

     SFAS No. 130, "Reporting Comprehensive Income," establishes standards for
reporting and display of "comprehensive income" and its components in a set of
financial statements. It requires that all items that are required to be
recognized under accounting standards as components of comprehensive income be
reported in a financial statement that is displayed with the same prominence as
other financial statements. Indian had no items of comprehensive income as
defined by SFAS No. 130 not included in the accompanying statements of
operations; therefore, statements of comprehensive income have not been
presented in the accompanying financial statements.

                                  (Continued)

3.   Property Acquisition

     In December 1997, Indian acquired certain producing Oklahoma and western
Arkansas properties from Sonat Exploration Inc. (Sonat) for approximately $30.2
million. Estimated proved reserves of the Sonat properties as of December 31,
1997 were 48.8 billion cubic feet of natural gas equivalent (unaudited). Indian
funded the purchase through borrowings under a line of credit and a term note.

     Included in the acquisition were numerous natural gas properties in which
Sonat had taken more or less than its ownership share of natural gas volumes
produced. On the acquisition date and through December 31, 1998, Indian was
unable to estimate the value of the volumetric imbalances which may ultimately
be settled in cash with other working interest owners. Accordingly, the purchase
price of the Sonat properties did not include a value for these acquired
volumetric imbalances. If the volumetric imbalances are settled in cash with
other working interest owners, Indian will record the settlements as other
revenues/expenses. Most of the volumetric imbalances between Indian and other
working interest owners are expected to be eliminated through production;
however, cash receipts or payments may occur as the individual properties
approach depletion.

     The acquisition of the Sonat properties described above was accounted for
by the purchase method and accordingly have been included in Indian's financial
statements from the date of the acquisition.

4.   Accounts Receivable

     Accounts receivable consisted of the following:

     Indian requires other joint interest owners to pay drilling costs in
advance. The advances are recorded as liabilities by Indian. Indian does not
require parties to collaterize amounts owing for joint interest billings after
completion of the well. To mitigate this credit risk, Indian has the ability to
offset amounts owed through application of revenues of joint interest owners and
also has the ability to file liens on the related properties.

     Accounts receivable - other, at December 31, 1998 represents amounts due
from Sonat for post closing adjustments to the purchase price of oil and natural
gas assets discussed in Note 3. Accounts receivable - other, at March 31, 2000,
represents amounts due from Indian selling numerous low-margin oil and natural
gas assets on March 31, 2000 for $1,462,000. The sales proceeds were received on
April 14, 2000.

                         Notes to Financial Statements
                                  (Continued)

1997 Line of Credit
-------------------

     In conjunction with the Sonat property acquisition in December 1997, Indian
established a line of a credit pursuant to which it can borrow up to an amount
determined by the bank based on evaluation of the assets and cash flow of
Indian. The established borrowing base at December 31, 1999 and March 31, 2000
was $20 million. Amounts borrowed under the line of credit bear interest at
various fixed rate options, which Indian may elect for periods up to 90 days.
Such rates are generally less than the prime rate. Indian may also elect to
borrow at the prime rate. The average interest rate at December 31, 1998 and
1999 and March 31, 2000 was 7.80%, 8.13% and 8.55%, respectively. The line of
credit is secured by essentially all of Indian's oil and natural gas properties.

     On March 31, 1999, in conjunction with the merger agreement with the Coral
Group, a monthly borrowing base reduction of $244,000 per month was established
for a period of eighty-two (82) months. On January 1, 2000, the bank renewed the
line of credit extending the maturity to January 15, 2001 and lowering the
borrowing base reduction to $215,000 per month.

1997 Term Loan
--------------

     Also in conjunction with the Sonat property acquisition in December 1997,
Indian established a $12 million term loan with a bank. Amounts borrowed under
the term loan bear interest at a specified prime rate redetermined annually. The
interest rate at December 31, 1998 and 1999 and March 31, 2000 was 8.00%, 8.25%
and 8.25%, respectively. The term loan is secured by certain assets of
affiliates of Indian.

     As discussed below, in March 1999, Indian repaid $6 million of the term
loan with proceeds received from its issuance of a $6 million production payment
obligation to the Coral Group.

     On February 1, 2000, the bank amended the term loan agreement extending its
maturity to March 1, 2001 and increased the loan's principal balance by
approximately $377,000 for accrued interest on the loan.

     As of December 31, 1999, Indian was not in compliance with certain
financial covenants required to be met under the 1997 line of credit and 1997
term loan. The financial institutions waived noncompliance with the debt
covenants.

Production Payment Obligation
-----------------------------

     In March 1999, as a result of the Agreement and Plan of Merger with the
Coral Group, the Coral Group loaned Indian $6 million in return for a monthly
production payment of $56,250 until the obligation is paid in full. The
production payment obligation is unsecured and interest free.

Subordinated 2003 Notes Payable
-------------------------------

     As of December 31, 1998 and 1999, Indian had $2 million of 10% (discounted
using a 13.7% interest rate) subordinated, unsecured notes payable to
stockholders. In conjunction with the December 1997 Sonat property acquisition
and execution of the 1997 line of credit, the terms of the subordinated 2003
notes were modified to defer all payments of interest until maturity of the 1997
line of credit. In connection with the

planned merger with the Coral Group, on February 14, 2000 the stockholders
contributed the notes to Indian's equity.

Subordinated 1998 Notes Payable
-------------------------------

     As of December 31, 1998 and 1999, Indian had two subordinated notes
payable, secured by treasury stock, outstanding. The notes were held by two
former stockholders and in April 1996 the notes were purchased by an affiliate
of Indian. The notes accrued interest at the national prime rate plus one half
percent, redetermined annually. The interest rate at December 31, 1998 and 1999
was 8.0% and 8.25%, respectively. In conjunction with the December 1997 Sonat
property acquisition and execution of the 1997 line of credit, the terms of the
subordinated notes were modified to defer all payments of interest until
maturity of the 1997 line of credit. In connection with the planned merger with
the Coral Group, on February 14, 2000 the affiliate contributed the notes to
Indian's equity.

Note Payable to Affiliate
-------------------------

     In October 1999, INDCO L.L.C. (INDCO), an entity with substantially the
same ownership as Indian loaned Indian $500,000 for an unsecured promissory
note. The note payable accrues interest at an annual rate of 6%. The principal
balance and accrued interest thereon are due December 31, 2001.

subsequent to December 31, 1999, are as follows:

                              INDIAN OIL COMPANY

                         Notes to Financial Statements
                                  (Continued)

     Indian has recognized $2.67 million of net deferred tax assets as of
December 31, 1999, which consist of various carryforwards available to offset
future income taxes. The carryforwards include federal net operating loss
carryforwards, the majority of which do not begin to expire until 2018, and
state net operating loss carryforwards, which expire primarily between 2006 and
2019. The tax benefits of carryforwards are recorded as an asset to the extent
that management assesses the utilization of such carryforwards to be "more
likely than not" realizable. When the future utilization of some portion of the
carryforwards is determined not to be likely, a valuation allowance is provided
to reduce the recorded tax benefits from such assets.

     Indian believes that its future taxable income will be sufficient to
utilize a significant amount of its carryforwards prior to their expiration.
Indian expects the tax benefit from the net operating loss and statutory
depletion carryforwards to be utilized between 2000 and 2009. Such expectation
is based upon current estimates of taxable income during this period.
Significant changes in such estimates caused by variables such as future oil and
natural gas prices or capital expenditures could alter the timing and amount of
utilization of such carryforwards. There can be no assurance that Indian will
generate any specific level of continuing taxable earnings.


8.   Stockholders' Equity

     On April 1, 1999, certain Indian stockholders transferred a total of 6,632
shares of their common stock, equal to 10% of Indian's outstanding shares, to
two individuals as additional compensation for prior services performed. The
individuals were officers of Indian who were terminated in March of 1999, as a
result of the Agreement and Plan of Merger with Canaan. Also on April 1, 1999,
as a result of a consulting arrangement between Indian and one of the
individuals discussed above, Indian issued 3,283 shares of its common stock to
the individual as additional compensation. Indian estimated the common shares
transferred or issued had no value on the date of issuance and transfer.
Accordingly, no compensation expense was recorded. The method used by management
to value Indian's common stock was based on the estimated fair value of proved
oil and natural gas reserves, and working capital at March 31, 1999, less non-
stockholder debt obligations and other noncurrent liabilities.

     On September 29, 1999, Indian's Chief Executive Officer and principal
stockholder granted the individual providing consulting services to Indian, an
option to purchase shares of the principal stockholders' common stock for $1.00
per share. The option may only be exercised when the individual's consulting
agreement is terminated as a result of a liquidation, reorganization or the
occurrence of other such transactions (a Transaction Event) by Indian. The
number of shares subject to the option is dependent on Indian's Transaction
Event value. The value of shares subject to the option is limited to $150,000.

     As disclosed in Note 1, in February 1999, Indian entered into an Agreement
and Plan of Merger with Canaan. Effective September 30, 1999, Indian and Canaan
agreed to Indian's merger value, thereby establishing the number of shares
subject to the purchase option. Indian recorded compensation expense of $149,000
based on the option's fair value.

     On October 10, 1999, Indian transferred certain assets to be excluded from
the merger with Canaan to INDCO, for two notes approximating $1,088,000. The
transferred assets included certain undeveloped leases, office fixtures, other
equipment and receivables due from Indian's officers and stockholders. The
notes'

                                  (Continued)

principal amount equaled the book value of transferred assets on the date of
transfer. Also in October 1999, Indian issued INDCO a $500,000 note for cash
(see Note 6). The $500,000 note payable to INDCO is expected to be repaid;
however, the notes receivable from INDCO are not expected to be collected and
have been accounted for as a distribution to stockholders.


9.   Employee Benefit Plan

     Employees of Indian, if eligible, may participate in a defined contribution
plan with features under Section 401(k) of the Internal Revenue Code. The plan
allows employees to make voluntary deferral contributions up to a maximum of 15%
of their compensation. Indian matches 50% of each employee's contribution up to
6% of such employee's compensation. Benefits payable under the plan are limited
to the amount of plan assets allocable to the account of each plan participant.
Indian retains the right to modify, amend or terminate the plan at any time. For
the years ended December 31, 1997, 1998 and 1999 and the three months ended
March 31, 1999 and 2000, Indian made matching contributions of $35,000, $44,000,
$31,000, $11,000 and $4,300, respectively.


10.  Related Party Transactions

     Indian subleased a condominium and leased a boat and an automobile from an
affiliate in 1997 and 1998. Indian reimbursed the affiliate for related expenses
incurred. Lease and reimbursement costs incurred by Indian approximated $77,000
and $71,000 for the years ended December 31, 1997 and 1998, respectively.

     Terms of the sublease and lease allowed Indian to cancel upon 30 days
notice. Indian terminated the lease in September 1998.

     During 1997, Indian received $100,000 from an affiliate, as a reimbursement
for management services provided. Such services were not provided in either 1998
or 1999.


11.  Commitments and Contingencies

     Indian leases its corporate offices through several lease obligations
expiring August 1, 2001 and leases field operations equipment expiring in July
2001. Minimum future rental payments under non-cancelable operating leases
having remaining terms in excess of one year as of December 31, 1999 are as
follows:

     Rent expense for the years ended December 31, 1997, 1998 and 1999
approximated $118,000, $292,000 and $389,000, respectively. Rent expense for the
three months ended March 31, 1999 and 2000 approximated $101,000 and $94,000,
respectively.

12.      Reduction of Carrying Cost of Oil and Natural Gas Properties

         Under the full cost method of accounting, the net book value of oil and
natural gas properties, less related deferred income taxes, may not exceed a
calculated "ceiling." The ceiling limitation is the discounted estimated
after-tax future net revenues from proved oil and natural gas properties. In
calculating future net revenues, current prices and costs are generally held
constant indefinitely. The net book value less deferred income taxes is compared
to the ceiling with any excess written off as an expense. An expense recorded in
one period may not be reversed in a subsequent period even though higher oil and
natural gas prices may have increased the ceiling applicable to the subsequent
period.

         At December 31, 1998, the carrying value of Indian's oil and natural
gas properties, less related deferred income taxes, exceeded the full cost
ceiling by $4 million. Accordingly, a $4 million pre-tax reduction of the
carrying value of such properties was recorded. This reduction was partially
offset by a $1.5 million deferred income tax benefit, resulting in an after-tax
charge of $2.5 million.


13.      Oil and Natural Gas Operations

         Below is a summary of results of operations for oil and natural gas
producing activities. The results do not include any allocation of Indian's
interest costs or general corporate overhead. Income tax expense (benefit) has
been calculated by applying statutory income tax rates to oil and gas sales
after deducting costs, including depreciation, depletion and amortization and
after giving effect to permanent differences, tax credits and allowances
relating to proved oil and gas reserves.

14.      Supplemental Information on Oil and Natural Gas Operations (Unaudited)

         The following supplemental unaudited information regarding the oil and
natural gas activities of Indian is presented pursuant to the disclosure
requirements promulgated by the Securities and Exchange Commission (SEC) and
SFAS No. 69 "Disclosures About Oil and Gas Producing Activities."

Oil and Natural Gas Quantities
------------------------------

         The reserve information for the year ended December 31, 1998 and 1999
presented below was prepared by the independent engineering firm of Netherland,
Sewell & Associates, Inc. Indian cautions that there are many uncertainties
inherent in estimating reserve quantities, and in projecting future production
rates and the timing of future development expenditures. In addition, reserve
estimates of new discoveries are more imprecise than those of properties with a
production history. Accordingly, these estimates are subject to change as
additional information becomes available.

         Proved oil and natural gas reserves are the estimated quantities of
crude oil, condensate, natural gas and natural gas liquids that geological and
engineering data demonstrate with reasonable certainty to be recoverable in
future years from known reservoirs under existing economic conditions. Proved
developed oil and natural gas reserves are those reserves expected to be
recovered through existing equipment and operating methods.

         Estimates of net quantities of proved reserves and proved developed
reserves of crude oil, including condensate and natural gas liquids, and natural
gas, as well as the changes in proved reserves during the periods indicated, are
set forth in the tables below. All reserves are located in the United States.

         Indian prepared the estimated reserves as of December 31, 1996 and 1997
based on geological and engineering evaluations performed as of December 31,
1998. The reserve estimates as of the prior year-end dates were derived by
analyzing actual historical production amounts and by adjusting the reserves
attributable to wells acquired or disposed of during the relevant periods. In
addition, in deriving the estimates as of December 31, 1996 and 1997, Indian
used production costs based on actual costs incurred during the years and actual
oil and natural gas prices received on December 31, 1996 and 1997. Indian has
estimated its reserves as of December 31, 1996 and 1997 in this manner because
the actual information necessary to calculate estimated proved reserves and
related information in accordance with guidelines of the SEC as of each date is
not available. Because the reserve estimates as of December 31, 1998 are based
on additional information gained from the result of drilling, testing and
production subsequent to the dates of the estimated reserves, the reserve
estimates as of December 31, 1996 and 1997 are not necessarily reflective of
quantities that might have been estimated based on information available as of
such dates had estimates in accordance

with SEC guidelines been made at such dates. Management believes that, because
of the methodology used, the reserve information presented is more reflective of
actual reserve quantities than estimates that might have been generated as of
such dates.

         On March 31, 2000, Indian sold 230 non-strategic oil and gas properties
to a third party for $1.46 million. The information as to changes in proved
reserves, standardized measure of discounted future net cash flows and changes
in the standardized measure does not include the effect of the sale.

Standardized Measure of Discounted Future Net Cash Flows
--------------------------------------------------------

         The following table sets forth the standardized measure of the
discounted future net cash flows attributable to Indian's proved oil and natural
gas reserves. Future cash inflows were computed by applying prices of oil and
natural gas being received at December 31 of each year presented to the
estimated future production of proved oil and natural gas reserves. All prices
were held constant except where definite price escalation is provided for in the
sales contracts.

         Future development and production costs are computed by estimating the
expenditures to be incurred in developing and producing proved oil and gas
reserves at the end of each year, based on respective year-end costs and
assuming continuation of existing economic conditions.


         Future income tax expenses are computed by applying appropriate
statutory rates to the future pre-tax net cash flows relating to proved
reserves, net of the tax basis of the properties involved giving effect to
permanent differences and tax credits and allowances relating to proved oil and
gas reserves.

15.      Liquidity

         As of March 31, 2000, Indian had a working capital deficiency of $22
million as a result of inclusion in Indian's current liabilities of $23.8
million of borrowings from the 1997 line of credit which matures in January 2001
and from the 1997 term loan which matures in March 2001.

         As disclosed in Note 1, Indian entered into an Agreement and Plan of
Merger with the Coral Group, whereby Indian will be acquired by Canaan for
shares of Canaan. If the merger is completed, Canaan will assume Indian's 1997
line of credit and 1997 term loan obligations and Canaan will seek to extend the
maturity date of the obligations or seek alternative financing from other
commercial lenders.

         If the merger with Canaan is not completed, the merger agreement
provides for the liquidation of Indian's assets, with any remaining proceeds
after satisfying Indian's obligations being shared equally between Indian's
stockholders and the Coral Group. If Indian is liquidated, management currently
believes proceeds from the sale of its assets would be sufficient to satisfy its
obligations. However, due to the effect of oil and natural gas prices on the
value of Indian's assets, there can be no assurance actual sales proceeds would
be sufficient to satisfy all of the obligations.

         1990 Limited Partnership
Oklahoma City, Oklahoma


         We have audited the balance sheets of Coral Reserves Natural Gas Income
Fund 1990 Limited Partnership as of December 31, 1998 and 1999 and the related
statements of operations, partners' equity and cash flows for each of the years
in the three year period ended December 31, 1999. These financial statements are
the responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves
Natural Gas Income Fund 1990 Limited Partnership as of December 31, 1998 and
1999, and the results of its operations and its cash flow for each of the years
in the three year period ended December 31, 1999 in conformity with generally
accepted accounting principles.

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves Natural Gas Income Fund 1990 Limited Partnership
     ("Partnership") is organized as an Oklahoma limited partnership. Coral
     Reserves, Inc., an Oklahoma corporation, and its two principal stockholders
     serve as Managing General Partner and Additional General Partners,
     respectively. The remaining 109 participants are limited partners.

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated among
     the partners as follows:

          .    The allowance for cost depletion is allocated 99% to the Limited
               Partners and 1% to the Managing General Partner.

          .    Depreciation of lease and well equipment and amortization of
               organization costs are allocated 99% to the Limited Partners and
               1% to the Managing General Partner.

          .    All other items of income and expense, with certain limited
               exceptions, and cash distributions are allocated 90% to the
               Limited Partners and 10% to the General Partners until payout is
               achieved. After payout, these items are allocated 75% to the
               Limited Partners and 25% to the General Partners. Payout occurs
               on an individual partner basis, and is reached at the point in
               time when cash distributions to a Limited Partner equal his or
               her capital contributions made to the Partnership. A portion of
               the Limited Partners reached payout status during 1995, and the
               remainder reached payout during 1996.

     The terms of the Partnership offering called for a subscription price of
     $100,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 38.875 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

                         Notes to Financial Statements
                                  (Continued)

     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma and Texas.

     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not captialize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less
     accumulated amortization plus estimated future development cost of proved
     undeveloped reserves are amortized by an equivalent unit-of-production
     method, converting natural gas to oil at the ratio approximating their
     relative energy content of one barrel ("Bbl") of oil to six thousand cubic
     feet ("Mcf") of natural gas. No gain or loss is recognized upon disposal of
     oil and natural gas properties unless such dispositions significantly alter
     the relationship between capitalized costs and proved oil and natural gas
     reserves.

        CORAL RESERVE NATURAL GAS INCOME FUND 1990 LIMITED PARTNERSHIP
                         Notes to Financial Statements
                                  (Continued)

     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances indicate that the carrying amount of an
     asset may not be recoverable. Recoverability of assets to be held and used
     is measured by a comparison of the carrying amount of an asset to future
     undiscounted net cash flows expected to be generated by the asset. If such
     assets are considered to be impaired, the impairment to be recognized is
     measured by the amount by which the carrying amount of the assets exceeds
     the fair market value of the assets. Assets to be disposed of are reported
     at the lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining recoverable reserves. No receivables are recorded for those wells
     where the Partnership has taken less than its ownership share of gas
     production.

                                  (Continued)

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1997 and
     1998, the Partnership's largest two purchasers accounted for approximately
     35%, and during 1999 the Partnership's three largest purchasers accounted
     for 35%, of its oil and natural gas revenues. The Partnership does not
     believe that the loss of any single customer would have a material effect
     on the results of its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Long-Term Debt

     The balances at December 31, 1999 and 1998 consist of a note payable to a
     bank. These borrowings have been made against a revolving line of credit
     maturing on April 15, 2001. The established borrowing base available to
     the Partnership under this credit facility was $750,000 at December 31,
     1999 and 1998, respectively. Borrowings bear interest at 1% above a
     specified prime rate and are collateralized by certain oil and gas
     properties of the Partnership, as well as guarantees by the Managing and
     Additional General Partners. The average interest rate under this credit
     facility outstanding at December 31, 1999 was 8.15%. At December 31, 1999
     and 1998, the balances of the revolving line of credit facility were
     classified as long-term, based on the Partnership's continuing intent and
     ability to refinance, as evidenced by the renewal of the credit facility in
     May 2000, extending the maturity date to April 15, 2001.

4.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

5.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves, Inc., the Managing
     General Partner of the Partnership, and certain affiliated partnerships,
     whose Managing General Partner is Coral Reserves, Inc. or Coral Reserves
     Energy Corp. Coral Reserves, Inc. and Coral Reserves Energy Corp. have
     common shareholders.

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of five percent
     (5%) of "Distributable Cash", as defined in the Partnership Agreement. Such
     overhead reimbursements amounted to $22,883, $30,676 and $40,086 for 1999,
     1998 and 1997, respectively, and are

                                  (Continued)

     Under an agreement between the Partnership and the Selling Agent, the
     Selling Agent is to receive compensation for services performed in the
     amount of 1 1/2% of Partnership gross annual revenues, plus 1% of
     Partnership monthly distributable cash before payout and an additional 1%
     after payout (paid solely out of the Managing General Partner's share of
     monthly distributable cash). Effective January 1, 1992, the Selling Agent
     sold the rights to these fees to Coral Reserves Natural Gas Income Fund
     1991 Limited Partnership ("Coral 1991"), with the sole exception being that
     the Selling Agent retained the additional 1% after payout interest in
     Partnership monthly distributable cash. Fees subsequently paid to Coral
     1991, in lieu of the Selling Agent, totaled $13,397, $18,603 and $22,191
     for the years ended December 31, 1999, 1998 and 1997, respectively. The
     Selling Agent must continue to perform the services for the Partnership as
     originally contracted.

7.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of the Partnership presented pursuant to the disclosure
     requirements promulgated by the Securities and Exchange Commission and
     Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
     and Gas Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The Partnership cautions that there are many uncertainties
     inherent in estimating reserve quantities, and in projecting future
     production rates and the timing of future development cost expenditures. In
     addition, reserve estimates of new discoveries are more imprecise than
     those of properties with a production history. Accordingly, these estimates
     are subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the changes in proved reserves during the periods
     indicated, are set forth in the tables below. All reserves are located in
     the United States.

     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, the Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information

     gained from the result of drilling, testing and production subsequent to
     the dates of the estimated reserves, the reserve estimates as of December
     31, 1996 and 1997 are not necessarily reflective of quantities that might
     have been estimated based on information available as of such dates had
     estimates in accordance with SEC guidelines been made at such dates.
     Management believes that, because of the methodology used, the reserve
     information presented is more reflective of actual reserve quantities than
     estimates that might have been generated as of such dates.

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

                         INDEPENDENT AUDITOR'S REPORT


To the Partners
Coral Reserves Natural Gas Income Fund
         1991 Limited Partnership
Oklahoma City, Oklahoma


         We have audited the balance sheets of Coral Reserves Natural Gas Income
Fund 1991 Limited Partnership as of December 31, 1998 and 1999 and the related
statements of operations, partners' equity and cash flows for each of the years
in the three year period ended December 31, 1999. These financial statements are
the responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves
Natural Gas Income Fund 1991 Limited Partnership as of December 31, 1998 and
1999, and the results of its operations and its cash flow for each of the years
in the three year period ended December 31, 1999 in conformity with generally
accepted accounting principles.

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves Natural Gas Income Fund 1991 Limited Partnership
     ("Partnership") is organized as an Oklahoma limited partnership. Coral
     Reserves, Inc., an Oklahoma corporation, and its two principal stockholders
     serve as Managing General Partner and Additional General Partners,
     respectively. The remaining 124 participants are limited partners.

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated among
     the partners as follows:

        .   The allowance for cost depletion is allocated 99% to the Limited
            Partners and 1% to the Managing General Partner.

        .   Depreciation of lease and well equipment and amortization of
            organization costs are allocated 99% to the Limited Partners and 1%
            to the Managing General Partner.

        .   All other items of income and expense, with certain limited
            exceptions, and cash distributions are allocated 90% to the Limited
            Partners and 10% to the General Partners until payout is achieved.
            After payout, these items are allocated 75% to the Limited Partners
            and 25% to the General Partners. Payout occurs on an individual
            partner basis, and is reached at the point in time when cash
            distributions to a Limited Partner equal his or her capital
            contributions made to the Partnership. A portion of the Limited
            Partners reached payout status during 1996, and the remainder
            reached payout during 1997.

     The terms of the Partnership offering called for a subscription price of
     $100,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 44.80 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

                         Notes to Financial Statement
                                  (Continued)


     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma and Texas.

     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not captialize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less
     accumulated amortization plus estimated future development cost of proved
     undeveloped reserves are amortized by an equivalent unit-of-production
     method, converting natural gas to oil at the ratio approximating their
     relative energy content of one barrel ("Bbl") of oil to six thousand cubic
     feet ("Mcf") of natural gas. No gain or loss is recognized upon disposal of
     oil and natural gas properties unless such dispositions significantly alter
     the relationship between capitalized costs and proved oil and natural gas
     reserves.

                         Notes to Financial Statement
                                  (Continued)


     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances indicate that the carrying amount of an
     asset may not be recoverable. Recoverability of assets to be held and used
     is measured by a comparison of the carrying amount of an asset to future
     undiscounted net cash flows expected to be generated by the asset. If such
     assets are considered to be impaired, the impairment to be recognized is
     measured by the amount by which the carrying amount of the assets exceeds
     the fair market value of the assets. Assets to be disposed of are reported
     at the lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining recoverable reserves. No receivables are recorded for those wells
     where the Partnership has taken less than its ownership share of gas
     production.

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1998 and
     1999, the Partnership's single largest purchaser accounted for
     approximately 30% and 20%, respectively, of its oil and natural gas
     revenues. During 1997, no single purchaser accounted for more than 10% of
     oil and natural gas revenues. The Partnership does not believe that the
     loss of any single customer would have a material effect on the results of
     its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Long-Term Debt

     The balances at December 31, 1998 and 1999 consist of a note payable to a
     bank. These borrowings have been made against a revolving line of credit
     maturing on October 1, 2000. The established borrowing base available to
     the Partnership under this credit facility was $750,000 at December 31,
     1999 and 1998. Borrowings bear interest at 1% above a specified prime rate
     and are collateralized by certain oil and gas properties of the
     Partnership, as well as guarantees by the Managing and Additional General
     Partners. The average interest rate under this credit facility outstanding
     at December 31, 1999 was 8.15%. At December 31, 1999 and 1998, the balances
     of the revolving line of credit facility were classified as long-term,
     based on the Partnership's continuing intent and ability to refinance, as
     evidenced by the renewal of the credit facility in May 2000, extending the
     maturity date to April 15, 2001.

4.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

5.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves Energy Corp., the
     Managing General Partner of the Partnership, and certain affiliated
     partnerships, whose Managing General Partner is Coral Reserves, Inc. or
     Coral Reserves Energy Corp. Coral Reserves, Inc. and Coral Reserves Energy
     Corp. have common shareholders.

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of five percent
     (5%) of "Distributable Cash", as defined in the Partnership Agreement. Such
     overhead reimbursements amounted to $35,154, $39,606, and $42,908 for 1999,
     1998 and 1997, respectively, and are included in "General and
     administrative" expenses in the accompanying statements of operations.

                         Notes to Financial Statement
                                  (Continued)


     During 1997, the Partnership sold interests in various producing oil and
     gas properties to Coral Reserves Energy Income Fund 1996 Limited
     Partnership and Coral Reserves 1996 Institutional Limited Partnership, two
     affiliated partnerships, for aggregate consideration of $193,246. The
     proceeds were accounted for as an adjustment to the capitalized oil and gas
     properties.

     Effective January 1, 1992, the Partnership purchased for $67,500 the rights
     to consulting fees paid by Coral Reserves Natural Gas Income Fund 1990
     Limited Partnership ("Coral 1990") to the Selling Agent of Coral 1990. The
     fees are paid by Coral 1990 for services performed by the Selling Agent,
     and consist of 1 1/2% of Coral 1990's gross annual revenues, plus 1% of
     monthly distributable cash before payout and an additional 1% after payout.
     The sole exception to this fee structure as purchased is that the Selling
     Agent will retain the additional 1% after payout interest in Partnership
     monthly distributable cash. Revenues received by the Partnership under this
     arrangement totaled $13,397, $18,603, and $22,191 for the years ended
     December 31, 1999, 1998 and 1997, respectively.

     Under an agreement between the Partnership and the Selling Agent, the
     Selling Agent is to receive compensation for services performed in the
     amount of 1 1/2% of Partnership gross annual revenues, plus 1% of
     Partnership monthly distributable cash before payout and an additional 1%
     after payout (paid solely out of the Managing General Partner's share of
     monthly distributable cash). Effective January 1, 1994, the Selling Agent
     sold the rights to these fees to Coral Reserves 1993 Institutional Limited
     Partnership ("Coral 1993-I"), with the sole exception being that the
     Selling Agent retained the additional 1% after payout interest in
     Partnership monthly distributable cash. Fees subsequently paid to Coral
     1993-I, in lieu of the Selling Agent, totaled $20,603, $23,936, and
     $24,188, for the years ended December 31, 1999, 1998 and 1997,
     respectively. The Selling Agent must continue to perform the services for
     the Partnership as originally contracted.

7.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of the Partnership presented pursuant to the disclosure
     requirements promulgated by the Securities and Exchange Commission and
     Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
     and Gas Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The Partnership cautions that there are many uncertainties
     inherent in estimating reserve quantities, and in projecting future
     production rates and the timing of future development cost expenditures. In
     addition, reserve estimates of new discoveries are more imprecise than
     those of properties with a production history. Accordingly, these estimates
     are subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

                                  (Continued)


     Estimates of net quantities of proved reserves of crude oil, including
     condensate and natural gas liquids, and natural gas, as well as the changes
     in proved reserves during the periods indicated, are set forth in the
     tables below. All reserves are located in the United States.

     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, The Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information gained from the result of drilling, testing and
     production subsequent to the dates of the estimated reserves, the reserve
     estimates as of December 31, 1996 and 1997 are not necessarily reflective
     of quantities that might have been estimated based on information available
     as of such dates had estimates in accordance with SEC guidelines been made
     at such dates. Management believes that, because of the methodology used,
     the reserve information presented is more reflective of actual reserve
     quantities than estimates that might have been generated as of such dates.

</TABLE>

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2,25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

     Principal changes in the standardized measure of discounted future net cash
     flows attributable to the Partnership's proved reserves are as follows:

To the Partners
Coral Reserves Natural Gas Income Fund
         1992 Limited Partnership
Oklahoma City, Oklahoma


         We have audited the balance sheets of Coral Reserves Natural Gas Income
Fund 1992 Limited Partnership as of December 31, 1998 and 1999 and the related
statements of operations, partners' equity and cash flows for each of the years
in the three year period ended December 31, 1999. These financial statements are
the responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves
Natural Gas Income Fund 1992 Limited Partnership as of December 31, 1998 and
1999, and the results of its operations and its cash flow for each of the years
in the three year period ended December 31, 1999 in conformity with generally
accepted accounting principles.

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves Natural Gas Income Fund 1992 Limited Partnership
     ("Partnership") is organized as an Oklahoma limited partnership. Coral
     Reserves Energy Corp., an Oklahoma corporation, and its two principal
     stockholders serve as Managing General Partner and Additional General
     Partners, respectively. The remaining 191 participants are limited
     partners.

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated among
     the partners as follows:

          .  The allowance for cost depletion is allocated 99% to the Limited
             Partners and 1% to the Managing General Partner.

          .  Depreciation of lease and well equipment and amortization of
             organization costs are allocated 99% to the Limited Partners and
             1% to the Managing General Partner.

          .  All other items of income and expense, with certain limited
             exceptions, and cash distributions are allocated 90% to the Limited
             Partners and 10% to the General Partners until payout is achieved.
             After payout, these items are allocated 75% to the Limited Partners
             and 25% to the General Partners. Payout occurs on an individual
             partner basis, and is reached at the point in time when cash
             distributions to a Limited Partner equal his or her capital
             contributions made to the Partnership. A portion of the Limited
             Partners reached payout status during 1999.

     The terms of the Partnership offering called for a subscription price of
     $100,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 75.00 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

                         Notes to Financial Statements
                                  (Continued)


     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma, Texas, Nebraska and Wyoming.

     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not capitalize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less
     accumulated amortization plus estimated future development cost of proved
     undeveloped reserves are amortized by an equivalent unit-of-production
     method, converting natural gas to oil at the ratio approximating their
     relative energy content of one barrel ("Bbl") of oil to six thousand cubic
     feet ("Mcf") of natural gas. No gain or loss is recognized upon disposal of
     oil and natural gas properties unless such dispositions significantly alter
     the relationship between capitalized costs and proved oil and natural gas
     reserves.

                         Notes to Financial Statements
                                  (Continued)

     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances indicate that the carrying amount of an
     asset may not be recoverable. Recoverability of assets to be held and used
     is measured by a comparison of the carrying amount of an asset to future
     undiscounted net cash flows expected to be generated by the asset. If such
     assets are considered to be impaired, the impairment to be recognized is
     measured by the amount by which the carrying amount of the assets exceeds
     the fair market value of the assets. Assets to be disposed of are reported
     at the lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining recoverable reserves. No receivables are recorded for those wells
     where the Partnership has taken less than its ownership share of gas
     production.

                                  (Continued)

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1997, 1998
     and 1999, the Partnership's largest three purchasers accounted for
     approximately 50%, of its oil and natural gas revenues. The Partnership
     does not believe that the loss of any single customer would have a material
     effect on the results of its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.


     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Long-Term Debt

     The balances at December 31, 1999 and 1998 consist of a note payable to a
     bank. These borrowings have been made against a revolving line of credit
     maturing on October 1, 2000. The established borrowing base available to
     the Partnership under this credit facility was $725,000 and $600,000 at
     December 31, 1999 and 1998, respectively. Borrowings bear interest at 1%
     above a specified prime rate and are collateralized by certain oil and gas
     properties of the Partnership, as well as guarantees by the Managing and
     Additional General Partners. The average interest rate under this credit
     facility outstanding at December 31, 1999 was 8.15%. At December 31, 1999
     and 1998, the balances of the revolving line of credit facility were
     classified as long-term, based on the Partnership's continuing intent and
     ability to refinance, as evidenced by the renewal of the credit facility in
     May 2000, extending the maturity date to April 15, 2001.

4.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

5.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves Energy Corp., the
     Managing General Partner of the Partnership.

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of five percent
     (5%) of "Distributable Cash", as defined in the Partnership Agreement. Such
     overhead reimbursements amounted to $42,042, $50,165, and $74,405 for 1999,
     1998 and 1997, respectively, and are included in "General and
     administrative" expenses in the accompanying statements of operations.

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The Partnership cautions that there are many uncertainties
     inherent in estimating reserve quantities, and in projecting future
     production rates and the timing of future development cost expenditures. In
     addition, reserve estimates of new discoveries are more imprecise than
     those of properties with a production history. Accordingly, these estimates
     are subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the changes in proved reserves during the periods
     indicated, are set forth in the tables below. All reserves are located in
     the United States.

     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, The Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information gained from the result of drilling, testing and
     production subsequent to the dates of the estimated reserves, the reserve
     estimates as of December 31, 1996 and 1997 are not necessarily reflective
     of quantities that might have been estimated based on information available
     as of such dates had estimates in accordance with SEC guidelines been made
     at such dates. Management believes that, because of the ethodology used,
     the reserve information presented is more reflective of actual reserve
     quantities than estimates that might have been generated as of such dates.

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

                         INDEPENDENT AUDITOR'S REPORT





To the Partners
Coral Reserves Natural Gas Income Fund
         1993 Limited Partnership
Oklahoma City, Oklahoma


         We have audited the balance sheets of Coral Reserves Natural Gas Income
Fund 1993 Limited Partnership as of December 31, 1998 and 1999 and the related
statements of operations, partners' equity and cash flows for each of the years
in the three year period ended December 31, 1999. These financial statements are
the responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves
Natural Gas Income Fund 1993 Limited Partnership as of December 31, 1998 and
1999, and the results of its operations and its cash flow for each of the years
in the three year period ended December 31, 1999 in conformity with generally
accepted accounting principles.

                         Notes to Financial Statements
                       December 31, 1997, 1998 and 1999
             (Information insofar as it relates to March 31, 2000

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves Natural Gas Income Fund 1993 Limited Partnership
     ("Partnership") is organized as an Oklahoma limited partnership. Coral
     Reserves Energy Corp., an Oklahoma corporation, and its two principal
     stockholders serve as Managing General Partner and Additional General
     Partners, respectively. The remaining 173 participants are limited
     partners.

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated among
     the partners as follows:

     .    The allowance for cost depletion is allocated 99% to the Limited
          Partners and 1% to the Managing General Partner.

     .    Depreciation of lease and well equipment and amortization of
          organization costs are allocated 99% to the Limited Partners and 1% to
          the Managing General Partner.

     .    All other items of income and expense, with certain limited
          exceptions, and cash distributions are allocated 90% to the Limited
          Partners and 10% to the General Partners until payout is achieved.
          After payout, these items are allocated 75% to the Limited Partners
          and 25% to the General Partners. Payout occurs on an individual
          partner basis, and is reached at the point in time when cash
          distributions to a Limited Partner equal his or her capital
          contributions made to the Partnership.

     The terms of the Partnership offering called for a subscription price of
     $100,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 65.250 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

                         Notes to Financial Statements
                                  (Continued)


     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma, Nebraska, Wyoming and Colorado.

     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Inventories

     Inventories are comprised of salvaged lease and well equipment and are
     accounted for at the lower of cost or fair market value. Items are removed
     from inventory utilizing the first-in, first-out method.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not captialize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less
     accumulated amortization plus estimated future development cost of proved
     undeveloped reserves are amortized by an equivalent unit-of-production
     method, converting natural gas to oil at the ratio approximating their
     relative energy content of

                                     F-91

        CORAL RESERVES NATURAL GAS INCOME FUND 1993 LIMITED PARTNERSHIP

                         Notes to Financial Statements
                                  (Continued)


     one barrel ("Bbl") of oil to six thousand cubic feet ("Mcf") of natural
     gas. No gain or loss is recognized upon disposal of oil and natural gas
     properties unless such dispositions significantly alter the relationship
     between capitalized costs and proved oil and natural gas reserves.

     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances indicate that the carrying amount of an
     asset may not be recoverable. Recoverability of assets to be held and used
     is measured by a comparison of the carrying amount of an asset to future
     undiscounted net cash flows expected to be generated by the asset. If such
     assets are considered to be impaired, the impairment to be recognized is
     measured by the amount by which the carrying amount of the assets exceeds
     the fair market value of the assets. Assets to be disposed of are reported
     at the lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining

     recoverable reserves. No receivables are recorded for those wells where the
     Partnership has taken less than its ownership share of gas production.

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1998 and
     1999, the Partnership's largest two purchasers accounted for approximately
     50% and 55%, respectively, and in 1997 its largest single purchaser
     accounted for 35% of its oil and natural gas revenues. The Partnership does
     not believe that the loss of any single customer would have a material
     effect on the results of its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Long-Term Debt

     The balances at December 31, 1999 and 1998 consist of a note payable to a
     bank. These borrowings have been made against a revolving line of credit
     maturing on October 1, 2000. The established borrowing base available to
     the Partnership under this credit facility was $600,000 at December 31,
     1999 and 1998, respectively. Borrowings bear interest at 1% above a
     specified prime rate and are collateralized by certain oil and gas
     properties of the Partnership, as well as guarantees by the Managing and
     Additional General Partners. The average interest rate under this credit
     facility outstanding at December 31, 1999 was 8.15%. At December 31, 1999
     and 1998, the balances of the revolving line of credit facility were
     classified as long-term, based on the Partnership's continuing intent and
     ability to refinance, as evidenced by the renewal of the credit facility in
     May 2000, extending the maturity date to April 15, 2001.

4.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

5.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves Energy Corp., the
     Managing General Partner of the Partnership, and certain affiliated
     partnerships, whose Managing General Partner is Coral Reserves, Inc. or
     Coral Reserves Energy Corp. Coral Reserves, Inc. and Coral Reserves Energy
     Corp. have common shareholders.

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of five percent
     (5%) of "Distributable Cash", as defined in the Partnership Agreement. Such
     overhead reimbursements amounted to $41,374, $50,869, and $80,000 for 1999,
     1998 and 1997, respectively, and are included in "General and
     administrative" expenses in the accompanying statements of operations.

                                  (Continued)


6.   Reduction of Carrying Cost of Oil and Natural Gas Properties

     Under the full cost method of accounting, the net book value of oil and
     natural gas properties may not exceed a calculated "ceiling." The ceiling
     limitation is the discounted estimated after-tax future net revenues from
     proved oil and natural gas properties. In calculating future net revenues,
     current prices and costs are generally held constant indefinitely. The net
     book value is compared to the ceiling with any excess written off as an
     expense. An expense recorded in one period may not be reversed in a
     subsequent period even though higher oil and natural gas prices may have
     increased the ceiling applicable to the subsequent period.

     At December 31, 1998, the carrying value of the Partnership's oil and
     natural gas properties exceeded the full cost ceiling by $244,823.
     Accordingly, a $245,000 reduction of the carrying value of such properties
     was recorded.

8.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of the Partnership presented pursuant to the disclosure
     requirements promulgated by the Securities and Exchange Commission and
     Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
     and Gas Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The Partnership cautions that there are many uncertainties
     inherent in estimating reserve quantities, and in projecting future
     production rates and the timing of future development cost expenditures. In
     addition, reserve estimates of new discoveries are more imprecise than
     those of properties with a production history. Accordingly, these estimates
     are subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the

     changes in proved reserves during the periods indicated, are set forth in
     the tables below. All reserves are located in the United States.

     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, the Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information gained from the result of drilling, testing and
     production subsequent to the dates of the estimated reserves, the reserve
     estimates as of December 31, 1996 and 1997 are not necessarily reflective
     of quantities that might have been estimated based on information available
     as of such dates had estimates in accordance with SEC guidelines been made
     at such dates. Management believes that, because of the methodology used,
     the reserve information presented is more reflective of actual reserve
     quantities than estimates that might have been generated as of such dates.

</TABLE>

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

     Principal changes in the standardized measure of discounted future net cash
     flows attributable to the Partnership's proved reserves are as follows:

To the Partners
Coral Reserves 1993 Institutional Limited Partnership
Oklahoma City, Oklahoma


         We have audited the balance sheets of Coral Reserves 1993 Institutional
Limited Partnership as of December 31, 1998 and 1999 and the related statements
of operations, partners' equity and cash flows for each of the years in the
three year period ended December 31, 1999. These financial statements are the
responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves 1993
Institutional Limited Partnership as of December 31, 19978 and 1999, and the
results of its operations and its cash flow for each of the years in the three
year period ended December 31, 1999 in conformity with generally accepted
accounting principles.

     $500,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 4.725 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma, Nebraska, Wyoming and New Mexico.

                                  (Continued)


     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not capitalize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less
     accumulated amortization plus estimated future development cost of proved
     undeveloped reserves are amortized by an equivalent unit-of-production
     method, converting natural gas to oil at the ratio approximating their
     relative energy content of one barrel ("Bbl") of oil to six thousand cubic
     feet ("Mcf") of natural gas. No gain or loss is recognized upon disposal of
     oil and natural gas properties unless such dispositions significantly alter
     the relationship between capitalized costs and proved oil and natural gas
     reserves.

     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable

                         Notes to Financial Statements
                                  (Continued)


     intangibles be reviewed for impairment whenever events or changes in
     circumstances indicate that the carrying amount of an asset may not be
     recoverable. Recoverability of assets to be held and used is measured by a
     comparison of the carrying amount of an asset to future undiscounted net
     cash flows expected to be generated by the asset. If such assets are
     considered to be impaired, the impairment to be recognized is measured by
     the amount by which the carrying amount of the assets exceeds the fair
     market value of the assets. Assets to be disposed of are reported at the
     lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining recoverable reserves. No receivables are recorded for those wells
     where the Partnership has taken less than its ownership share of gas
     production.

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1997 the
     Partnership's largest single purchaser accounted for approximately 20% and
     during 1998 and 1999 the Partnership's largest two purchasers accounted for
     30% and 35%, respectively, of its

                                  (Continued)

     oil and natural gas revenues. The Partnership does not believe that the
     loss of any single customer would have a material effect on the results of
     its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Long-Term Debt

     The balances at December 31, 1999 and 1998 consist of a note payable to a
     bank. These borrowings have been made against a revolving line of credit
     maturing on October 1, 2000. The established borrowing base available to
     the Partnership under this credit facility was $600,000 and $500,000 at
     December 31, 1999 and 1998, respectively. Borrowings bear interest at 1%
     above a specified prime rate and are collateralized by certain oil and gas
     properties of the Partnership, as well as

     guarantees by the Managing and Additional General Partners. The average
     interest rate under this credit facility outstanding at December 31, 1999
     was 8.15%. At December 31, 1999 and 1998, the balances of the revolving
     line of credit facility were classified as long-term, based on the
     Partnership's continuing intent and ability to refinance, as evidenced by
     the renewal of the credit facility in May 2000, extending the maturity date
     to April 15, 2001.

4.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

5.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves, Inc., the Managing
     General Partner of the Partnership, and certain affiliated partnerships,
     whose Managing General Partner is Coral Reserves, Inc. or Coral Reserves
     Energy Corp. Coral Reserves, Inc. and Coral Reserves Energy Corp. have
     common shareholders.

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of three
     percent (3%) of "Distributable Cash", as defined in the Partnership
     Agreement. Such overhead reimbursements amounted to $14,210, $13,580, and
     $20,611 for 1999, 1998 and 1997, respectively, and are included in "General
     and administrative" expenses in the accompanying statements of operations.

     Effective January 1, 1994, the Partnership purchased for $106,123 the
     rights to consulting fees paid by Coral Reserves Natural Gas Income Fund
     1991 Limited Partnership ("Coral 1991") to the Selling Agent of Coral 1991.
     The fees are paid by Coral 1991 for services performed by the Selling
     Agent, and consist of 1 1/2% of Coral 1991's gross annual revenues, plus 1%
     of monthly distributable cash before payout and an additional 1% after
     payout. The sole exception to this fee structure as purchased is that the
     Selling Agent will retain the additional 1% after payout interest

     in Partnership monthly distributable cash. Revenues received by the
     Partnership under this arrangement totaled $20,603, $23,937 and $24,645 for
     the years ended December 31, 1999, 1998 and 1997, respectively.

6.   Reduction of Carrying Cost of Oil and Natural Gas Properties

     Under the full cost method of accounting, the net book value of oil and
     natural gas properties may not exceed a calculated "ceiling." The ceiling
     limitation is the discounted estimated after-tax future net revenues from
     proved oil and natural gas properties. In calculating future net revenues,
     current prices and costs are generally held constant indefinitely. The net
     book value is compared to the ceiling with any excess written off as an
     expense. An expense recorded in one period may not be reversed in a
     subsequent period even though higher oil and natural gas prices may have
     increased the ceiling applicable to the subsequent period.

     At December 31, 1998, the carrying value of the Partnership's oil and
     natural gas properties exceeded the full cost ceiling by $99,640.
     Accordingly, a $100,000 reduction of the carrying value of such properties
     was recorded.

8.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of the Partnership presented pursuant to the disclosure
     requirements promulgated by the Securities and Exchange Commission and
     Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
     and Gas Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The Partnership cautions that there are many uncertainties
     inherent in estimating reserve quantities, and in projecting future
     production rates and the timing of future development cost expenditures. In
     addition, reserve estimates of new discoveries are more imprecise than
     those of properties with a production history. Accordingly, these estimates
     are subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the changes in proved reserves during the periods
     indicated, are set forth in the tables below. All reserves are located in
     the United States.

                         Notes to Financial Statements
                                  (Continued)

     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, The Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information gained from the result of drilling, testing and
     production subsequent to the dates of the estimated reserves, the reserve
     estimates as of December 31, 1996 and 1997 are not necessarily reflective
     of quantities that might have been estimated based on information available

     at such dates. Management believes that, because of the methodology used,
     the reserve information presented is more reflective of actual reserve
     quantities than estimates that might have been generated as of such dates.

</TABLE>

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

     Principal changes in the standardized measure of discounted future net cash
     flows attributable to the Partnership's proved reserves are as follows:

To the Partners
Coral Reserves Energy Income Fund
         1995 Limited Partnership
Oklahoma City, Oklahoma


         We have audited the balance sheets of Coral Reserves Energy Income Fund
1995 Limited Partnership as of December 31, 1998 and 1999 and the related
statements of operations, partners' equity and cash flows for each of the years
in the three year period ended December 31, 1999. These financial statements are
the responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves
Energy Income Fund 1995 Limited Partnership as of December 31, 1998 and 1999,
and the results of its operations and its cash flow for each of the years in the
three year period ended December 31, 1999 in conformity with generally accepted
accounting principles.

                         Notes to Financial Statements
                       December 31, 1997, 1998 and 1999
             (Information insofar as it relates to March 31, 2000
        or the three months ended March 31, 1999 and 2000 is unaudited)


1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves Energy Income Fund 1995 Limited Partnership ("Partnership")
     is organized as an Oklahoma limited partnership. Coral Reserves Energy
     Corp., an Oklahoma corporation, and its two principal stockholders serve as
     Managing General Partner and Additional General Partners, respectively. The
     remaining 196 participants are limited partners.

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated among
     the partners as follows:

          .    The allowance for cost depletion is allocated 99% to the Limited
               Partners and 1% to the Managing General Partner.

          .    Depreciation of lease and well equipment and amortization of
               organization costs are allocated 99% to the Limited Partners and
               1% to the Managing General Partner.

          .    All other items of income and expense, with certain limited
               exceptions, and cash distributions are allocated 90% to the
               Limited Partners and 10% to the General Partners until payout is
               achieved. After payout, these items are allocated 75% to the
               Limited Partners and 25% to the General Partners. Payout occurs
               on an individual partner basis, and is reached at the point in
               time when cash distributions to a Limited Partner equal his or
               her capital contributions made to the Partnership.

     The terms of the Partnership offering called for a subscription price of
     $100,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 68.050 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

                         Notes to Financial Statements
                                  (Continued)



     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma, Arkansas and Wyoming.

     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Inventories

     Inventories are comprised of salvaged lease and well equipment and are
     accounted for at the lower of cost or fair market value. Items are removed
     from inventory utilizing the first-in, first-out method.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not capitalize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less

     one barrel ("Bbl") of oil to six thousand cubic feet ("Mcf") of natural
     gas. No gain or loss is recognized upon disposal of oil and natural gas
     properties unless such dispositions significantly alter the relationship
     between capitalized costs and proved oil and natural gas reserves.

     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances indicate that the carrying amount of an
     asset may not be recoverable. Recoverability of assets to be held and used
     is measured by a comparison of the carrying amount of an asset to future
     undiscounted net cash flows expected to be generated by the asset. If such
     assets are considered to be impaired, the impairment to be recognized is
     measured by the amount by which the carrying amount of the assets exceeds
     the fair market value of the assets. Assets to be disposed of are reported
     at the lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining

     recoverable reserves. No receivables are recorded for those wells where the
     Partnership has taken less than its ownership share of gas production.

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1997, the
     Partnership's largest single purchaser accounted for approximately 50% and
     during 1998 the Partnership's largest three purchasers accounted for 70% of
     its oil and natural gas revenues. During 1999, the Partnership's two
     largest purchasers accounted for 65% of its oil and natural gas revenues.
     The Partnership does not believe that the loss of any single customer would
     have a material effect on the results of its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk. At December 31,
     1999, a significant concentration of credit risk existed with respect to
     $234,216 deposited with one financial institution.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Long-Term Debt

     A revolving line of credit maturing on October 1, 2000, was established in
     September 1999. Borrowings bear interest at 1% above a specified prime rate
     and are collateralized by certain oil and gas properties of the
     Partnership, as well as guarantees by the Managing and Additional General
     Partners. The borrowing base available to the Partnership under this credit
     facility is $2,000,000. No borrowings have been made under this line of
     credit as of December 31, 1999. An initial draw of $10,000 was made against
     the line of credit in March, 2000. The balance of the revolving line of
     credit facility was reclassified as long-term, based on the Partnership's
     continuing intent and ability to refinance, as evidenced by the renewal of
     the credit facility in May 2000, extending the maturity date to April 15,
     2001.

4.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

5.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves Energy Corp., the
     Managing General Partner of the Partnership

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of five percent
     (5%) of "Distributable Cash", as defined in the Partnership Agreement. Such
     overhead reimbursements amounted to $59,253, $58,639, and $78,659 for 1999,
     1998 and 1997, respectively, and are included in "General and
     administrative" expenses in the accompanying statements of operations.

7.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of the Partnership presented pursuant to the disclosure
     requirements promulgated by the Securities and Exchange Commission and
     Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
     and Gas Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The

          CORAL RESERVES ENERGY INCOME FUND 1995 LIMITED PARTNERSHIP

                         Notes to Financial Statements
                                  (Continued)


     Partnership cautions that there are many uncertainties inherent in
     estimating reserve quantities, and in projecting future production rates
     and the timing of future development cost expenditures. In addition,
     reserve estimates of new discoveries are more imprecise than those of
     properties with a production history. Accordingly, these estimates are
     subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the changes in proved reserves during the periods
     indicated, are set forth in the tables below. All reserves are located in
     the United States.

     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, The Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information gained from the result of drilling, testing and
     production subsequent to the dates of the estimated reserves, the reserve
     estimates as of December 31, 1996 and 1997 are not necessarily reflective
     of quantities that might have been estimated based on information available
     as of such dates had estimates in accordance with SEC guidelines been made
     at such dates. Management believes that, because of the methodology used,
     the reserve information presented is more reflective of actual reserve
     quantities than estimates that might have been generated as of such dates.

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

                         INDEPENDENT AUDITOR'S REPORT





To the Partners
Coral Reserves Energy Income Fund
         1996 Limited Partnership
Oklahoma City, Oklahoma


     We have audited the balance sheets of Coral Reserves Energy Income Fund
1996 Limited Partnership as of December 31, 1998 and 1999 and the related
statements of operations, partners' equity and cash flows for each of the years
in the three year period ended December 31, 1999. These financial statements are
the responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves Energy Income
Fund 1996 Limited Partnership as of December 31, 1998 and 1999, and the results
of its operations and its cash flow for each of the years in the three year
period ended December 31, 1999 in conformity with generally accepted accounting
principles.

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves Energy Income Fund 1996 Limited Partnership ("Partnership")
     is organized as an Oklahoma limited partnership. Coral Reserves Energy
     Corp., an Oklahoma corporation, and its two principal stockholders serve as
     Managing General Partner and Additional General Partners, respectively. The
     remaining 226 participants are limited partners.

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated among
     the partners as follows:

        .   The allowance for cost depletion is allocated 99% to the Limited
            Partners and 1% to the Managing General Partner.

        .   Depreciation of lease and well equipment and amortization of
            organization costs are allocated 99% to the Limited Partners and 1%
            to the Managing General Partner.

        .   All other items of income and expense, with certain limited
            exceptions, and cash distributions are allocated 90% to the Limited
            Partners and 10% to the General Partners until payout is achieved.
            After payout, these items are allocated 75% to the Limited Partners
            and 25% to the General Partners. Payout occurs on an individual
            partner basis, and is reached at the point in time when cash
            distributions to a Limited Partner equal his or her capital
            contributions made to the Partnership.

     The terms of the Partnership offering called for a subscription price of
     $100,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 96.350 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma and Texas.

                         Notes to Financial Statements
                                  (Continued)


     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not captialize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less
     accumulated amortization plus estimated future development cost of proved
     undeveloped reserves are amortized by an equivalent unit-of-production
     method, converting natural gas to oil at the ratio approximating their
     relative energy content of one barrel ("Bbl") of oil to six thousand cubic
     feet ("Mcf") of natural gas. No gain or loss is recognized upon disposal of
     oil and natural gas properties unless such dispositions significantly alter
     the relationship between capitalized costs and proved oil and natural gas
     reserves.

     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances

     indicate that the carrying amount of an asset may not be recoverable.
     Recoverability of assets to be held and used is measured by a comparison of
     the carrying amount of an asset to future undiscounted net cash flows
     expected to be generated by the asset. If such assets are considered to be
     impaired, the impairment to be recognized is measured by the amount by
     which the carrying amount of the assets exceeds the fair market value of
     the assets. Assets to be disposed of are reported at the lower of the
     carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining recoverable reserves. No receivables are recorded for those wells
     where the Partnership has taken less than its ownership share of gas
     production.

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1997, the
     Partnership's largest five purchasers accounted for approximately 80%, and
     during 1998 the largest two purchasers accounted for 50% of its oil and
     natural gas revenues. During 1999, the Partnership's three largest
     purchasers accounted for 60% of its oil and natural gas

     revenues. The Partnership does not believe that the loss of any single
     customer would have a material effect on the results of its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Notes Receivable

     Effective February 1999, the Partnership made an advance of $3,200,000 to
     Indian Oil Company (Indian). In return for the advance, the Partnership
     receives a production payment payable from Indian in the amount of $30,000
     per month.

4.   Long-Term Debt

     The balance at December 31, 1999 consists of a note payable to a bank.
     These borrowings have been made against a revolving line of credit maturing
     on October 1, 2000. The established borrowing base available to the
     Partnership under this credit facility was $2,400,000 at December 31, 1999.
     Borrowings bear interest at 1% above a specified prime rate and are
     collateralized by certain oil and gas properties of the Partnership, as
     well as guarantees by the Managing and Additional General Partners. The
     average interest rate under this credit facility outstanding at December
     31, 1999 was 8.19%. At December 31, 1999, the balance of the revolving line
     of credit facility was reclassified as long-term, based on the
     Partnership's continuing intent and ability to refinance, as evidenced by
     the renewal of the credit facility in May 2000, extending the maturity date
     to April 15, 2001.

5.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

6.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves Energy Corp., the
     Managing General Partner of the Partnership, and certain affiliated
     partnerships, whose Managing General Partner is Coral Reserves, Inc. or
     Coral Reserves Energy Corp. Coral Reserves, Inc. and Coral Reserves Energy
     Corp. have common shareholders.

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of five percent
     (5%) of "Distributable Cash", as defined in the Partnership Agreement. Such
     overhead reimbursements amounted to $80,193, $53,583 and $24,511 for 1999,
     1998 and 1997, respectively, and are included in "General and
     administrative" expenses in the accompanying statements of operations.

     During 1997, the Partnership purchased interests in various producing oil
     and gas properties from Coral Reserves Natural Gas Income Fund 1991 Limited
     Partnership, for aggregate consideration of $96,623.

7.   Reduction of Carrying Cost of Oil and Natural Gas Properties

     Under the full cost method of accounting, the net book value of oil and
     natural gas properties may not exceed a calculated "ceiling." The ceiling
     limitation is the discounted estimated after-tax future net revenues from
     proved oil and natural gas properties. In calculating future net revenues,
     current prices and costs are generally held constant indefinitely. The net
     book value is compared to the ceiling with any excess written off as an
     expense. An expense recorded in one period may not be reversed in a
     subsequent period even though higher oil and natural gas prices may have
     increased the ceiling applicable to the subsequent period.

     At December 31, 1998, the carrying value of the Partnership's oil and
     natural gas properties exceeded the full cost ceiling by $886,779.
     Accordingly, a $887,000 reduction of the carrying value of such properties
     was recorded.

9.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of the Partnership presented pursuant to the disclosure
     requirements promulgated by the Securities and Exchange Commission and
     Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
     and Gas Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999 The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The Partnership cautions that there are many uncertainties
     inherent in estimating reserve quantities, and in projecting future
     production rates and the timing of future development cost expenditures. In
     addition, reserve estimates of new discoveries are more imprecise than
     those of properties with a production history. Accordingly, these estimates
     are subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the changes in proved reserves during the periods
     indicated, are set forth in the tables below. All reserves are located in
     the United States.

                         Notes to Financial Statements
                                  (Continued)


     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, The Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information gained from the result of drilling, testing and
     production subsequent to the dates of the estimated reserves, the reserve
     estimates as of December 31, 1996 and 1997 are not necessarily reflective
     of quantities that might have been estimated based on information available
     as of such dates had estimates in accordance with SEC guidelines been made
     at such dates. Management believes that, because of the methodology used,
     the reserve information presented is more reflective of actual reserve
     quantities than estimates that might have been generated as of such dates.

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

                         INDEPENDENT AUDITOR'S REPORT



To the Partners
Coral Reserves 1996 Institutional Limited Partnership
Oklahoma City, Oklahoma


         We have audited the balance sheets of Coral Reserves 1996 Institutional
Limited Partnership as of December 31, 1998 and 1999 and the related statements
of operations, partners' equity and cash flows for each of the years in the
three year period ended December 31, 1999. These financial statements are the
responsibility of the Partnership's Managing General Partner. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 Coral Reserves 1996
Institutional Limited Partnership as of December 31, 1998 and 1999, and the
results of its operations and its cash flow for each of the years in the three
year period ended December 31, 1999 in conformity with generally accepted
accounting principles.

             (Information insofar as it relates to March 31, 2000

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves 1996 Institutional Limited Partnership ("Partnership") is
     organized as an Oklahoma limited partnership. Coral Reserves Energy Corp.,
     an Oklahoma corporation, and its two principal stockholders serve as
     Managing General Partner and Additional General Partners, respectively. The
     remaining 54 participants are limited partners.

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated among
     the partners as follows:

          .   The allowance for cost depletion is allocated 99% to the Limited
              Partners and 1% to the Managing General Partner.

          .   Depreciation of lease and well equipment and amortization of
              organization costs are allocated 99% to the Limited Partners and
              1% to the Managing General Partner.

          .   All other items of income and expense, with certain limited
              exceptions, and cash distributions are allocated 87.5% to the
              Limited Partners and 12.5% to the General Partners.

     The terms of the Partnership offering called for a subscription price of
     $500,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 13.040 units in
     the Partnership.

     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

                         Notes to Financial Statements
                                  (Continued)


     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma and Texas.

     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Property and Equipment

     The Partnership follows the full cost method of accounting for its oil and
     natural gas properties. Accordingly, all costs incidental to the
     acquisition, exploration, and development of oil and gas properties,
     including costs of undeveloped leasehold, dry holes and leasehold
     equipment, are capitalized. The Partnership does not captialize any
     internal costs as part of the full cost pool. Net capital costs
     (capitalized costs less accumulated amortization) are limited to the
     estimated future net revenues, discounted at 10% per annum, from proved
     oil, natural gas and natural gas liquids reserves plus the lower of cost or
     estimated fair market value of undeveloped properties subject to
     amortization. The Partnership subjects all costs of undeveloped properties
     to amortization, as such costs are insignificant. Capitalized costs less
     accumulated amortization plus estimated future development cost of proved
     undeveloped reserves are amortized by an equivalent unit-of-production
     method, converting natural gas to oil at the ratio approximating their
     relative energy content of one barrel ("Bbl") of oil to six thousand cubic
     feet ("Mcf") of natural gas. No gain or loss is recognized upon disposal of
     oil and natural gas properties unless such dispositions significantly alter
     the relationship between capitalized costs and proved oil and natural gas
     reserves.

                         Notes to Financial Statements
                                  (Continued)


     The Partnership accounts for its non-oil and natural gas long-lived assets
     in accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances indicate that the carrying amount of an
     asset may not be recoverable. Recoverability of assets to be held and used
     is measured by a comparison of the carrying amount of an asset to future
     undiscounted net cash flows expected to be generated by the asset. If such
     assets are considered to be impaired, the impairment to be recognized is
     measured by the amount by which the carrying amount of the assets exceeds
     the fair market value of the assets. Assets to be disposed of are reported
     at the lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the Partnership receives production
     proceeds, from the purchaser and further distributes such amounts to other
     revenue and royalty owners. Production proceeds applicable to other revenue
     and royalty owners are reflected as revenue and royalty distributions
     payable in the accompanying balance sheets. The Partnership accrues revenue
     for only its net interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated
     remaining recoverable reserves. No receivables are recorded for those wells
     where the Partnership has taken less than its ownership share of gas
     production.

     Major Purchasers

     The Partnership markets its oil and natural gas production to numerous
     purchasers under a combination of short-term contracts. During 1997, the
     Partnership's largest five purchasers accounted for approximately 80%, and
     during 1998 and 1999 the largest two purchasers accounted for 50% and 65%,
     respectively, of it's oil and natural gas revenues. The Partnership does
     not believe that the loss of any single customer would have a material
     effect on the results of its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Notes Receivable

     Effective February 1999, the Partnership made an advance of $2,800,000 to
     Indian Oil Company (Indian). In return for the advance, the Partnership
     receives a production payment payable from Indian in the amount of $26,250
     per month.

4.   Long-Term Debt

     The balance at December 31, 1999 consists of a note payable to a bank.
     These borrowings have been made against a revolving line of credit maturing
     on October 1, 2000. The established borrowing base available to the
     Partnership under this credit facility was $1,950,000 at December 31, 1999.
     Borrowings bear interest at 1% above a specified prime rate and are
     collateralized by certain oil and gas properties of the Partnership, as
     well as guarantees by the Managing and Additional General Partners. The
     average interest rate under this credit facility outstanding at December
     31, 1999 was 8.19%. At December 31, 1999, the balance of the revolving line
     of credit facility was reclassified as long-term, based on the
     Partnership's continuing intent and ability to refinance, as evidenced by
     the renewal of the credit facility in May 2000, extending the maturity date
     to April 15, 2001.

5.   Income Taxes

     The items of taxable income and expense generated by Partnership operations
     are includable in the income tax returns of the partners, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The Partnership income tax returns, the
     qualifications of the Partnership as such for tax purposes, and the amount
     of the Partnership's taxable income or loss are subject to examination by
     federal and state taxing authorities. If such examinations resulted in
     changes with respect to the partnership qualification or in changes to
     taxable partnership income or loss, the tax liability of the partners could
     change accordingly.

6.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnership
     engaged in certain transactions with Coral Reserves Energy Corp., the
     Managing General Partner of the Partnership, and certain affiliated
     partnerships, whose Managing General Partner is Coral Reserves, Inc. or
     Coral Reserves Energy Corp. Coral Reserves, Inc. and Coral Reserves Energy
     Corp. have common shareholders.

     The Partnership is required to reimburse the Managing General Partner for
     overhead expenses, including office rent and salaries for clerical staff
     and appropriate production supervisory personnel, or any other overhead
     expenses which the Managing General Partner deems reasonable. The
     reimbursement for overhead expenses is limited to a maximum of five percent
     (5%) of "Distributable Cash", as defined in the Partnership Agreement. Such
     overhead reimbursements amounted to $40,390, $53,583, and $24,511 for 1999,
     1998 and 1997, respectively, and are

     included in "General and administrative" expenses in the accompanying
     statements of operations.

     During 1997, the Partnership purchased interests in various producing oil
     and gas properties from Coral Reserves Natural Gas Income Fund 1991 Limited
     Partnership, for aggregate consideration of $96,623.


7.   Reduction of Carrying Cost of Oil and Natural Gas Properties

     Under the full cost method of accounting, the net book value of oil and
     natural gas properties may not exceed a calculated "ceiling." The ceiling
     limitation is the discounted estimated after-tax future net revenues from
     proved oil and natural gas properties. In calculating future net revenues,
     current prices and costs are generally held constant indefinitely. The net
     book value is compared to the ceiling with any excess written off as an
     expense. An expense recorded in one period may not be reversed in a
     subsequent period even though higher oil and natural gas prices may have
     increased the ceiling applicable to the subsequent period.

     At December 31, 1998, the carrying value of the Partnership's oil and
     natural gas properties exceeded the full cost ceiling by $886,779.
     Accordingly, a $887,000 reduction of the carrying value of such properties
     was recorded.

9.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of the Partnership presented pursuant to the disclosure
     requirements promulgated by the Securities and Exchange Commission and
     Statement of Financial Accounting Standards No. 69, "Disclosures About Oil
     and Gas Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. The Partnership's proved reserves were
     calculated by the independent petroleum consultants of Netherland, Sewell &
     Associates, Inc. The Partnership cautions that there are many uncertainties
     inherent in estimating reserve quantities, and in projecting future
     production rates and the timing of future development cost expenditures. In
     addition, reserve estimates of new discoveries are more imprecise than
     those of properties with a production history. Accordingly, these estimates
     are subject to change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the

                         Notes to Financial Statements
                                  (Continued)

     changes in proved reserves during the periods indicated, are set forth in
     the tables below. All reserves are located in the United States.

     The Partnership prepared the estimated reserves as of December 31, 1996 and
     1997 based on geological and engineering evaluations performed as of
     December 31, 1998. The reserve estimates as of the prior year-end dates
     were derived by analyzing actual historical production amounts and by
     adjusting the reserves attributable to wells acquired or disposed of during
     the relevant periods. In addition, in deriving the estimates as of December
     31, 1996 and 1997, The Partnership used production costs based on actual
     costs incurred during the years and actual oil and natural gas prices
     received on December 31, 1996 and 1997. The Partnership has estimated its
     reserves as of December 31, 1996 and 1997 in this manner because the actual
     information necessary to calculate estimated proved reserves and related
     information in accordance with guidelines of the SEC as of each date is not
     available. Because the reserve estimates as of December 31, 1998 are based
     on additional information gained from the result of drilling, testing and
     production subsequent to the dates of the estimated reserves, the reserve
     estimates as of December 31, 1996 and 1997 are not necessarily reflective
     of quantities that might have been estimated based on information available
     as of such dates had estimates in accordance with SEC guidelines been made
     at such dates. Management believes that, because of the methodology used,
     the reserve information presented is more reflective of actual reserve
     quantities than estimates that might have been generated as of such dates.

     Future cash inflows are computed by applying year-end prices (averaging
     $22.75 per barrel of oil, adjusted for transportation and other charges,
     and $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities
     of proved reserves, except where fixed and determinable price changes are
     provided by contractual arrangements in existence at year-end. Future
     development and production costs are computed by estimating the
     expenditures to be incurred in developing and producing proved oil and gas
     reserves at the end of the year, based on year-end costs and assuming
     continuation of existing economic conditions.

     Principal changes in the standardized measure of discounted future net cash
     flows attributable to the Partnership's proved reserves are as follows:

                         Notes to Financial Statements

Summary of significant accounting policies

     This summary of significant accounting policies of Canaan Securities, Inc.
     (the "Company") is presented to assist in understanding the Company's
     financial statements. The financial statements and notes are
     representations of the Company's management who is responsible for their
     integrity and objectivity. These accounting policies conform to generally
     accepted accounting principles and have been consistently applied in the
     preparation of the financial statements.

     Description of business - Canaan Securities, Inc. was incorporated in the
     State of Delaware in 1989.
         The Company is a registered broker/dealer engaged in selling interests
         in oil and gas limited partnerships and is subject to certain
         regulations of the Securities and Exchange Commission (SEC) and the
         National Association of Securities Dealers, Inc. (NASD).

     Accounting period - the Company maintains a calendar year-end for both
         fiscal and tax purposes.

     Revenue recognition - commission income is recognized by the Company as of
         the date of acceptance of the limited partners' investment. All other
         income is recognized when earned.

     Cash and cash equivalents - the Company considers all short term
         investments with an original maturity of 90 days or less to be cash
         equivalents.

     Office furniture and equipment - office furniture and equipment are
         recorded at cost. Depreciation is provided on a straight-line basis
         over the estimated useful lives of the assets, generally 5 to 10 years.

     Income taxes - income taxes are provided for the tax effects of
         transactions reported in the financial statements and consist of taxes
         currently due plus deferred taxes related primarily to differences
         between financial and income tax reporting. The deferred tax assets and
         liabilities represent the future tax return consequences of those
         differences, which will either be taxable or deductible when the assets
         and liabilities are recovered or settled. Deferred taxes also are
         recognized for operating losses that are available to offset future
         taxable income.

     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.

Officer loan receivable

     This represents various advances to the Company's officer/sole stockholder
     under a note dated January 31, 1994, and extended in 1997. Under the
     agreement, the principal balance outstanding is not to exceed $300,000 and
     is payable on demand. Interest accrues at the rate of 6% per annum, and is
     payable quarterly. In 1997, the maturity date of the note was extended to
     June 15, 2002. Interest income recorded on these advances was $4,904 and
     $5,621 for the years ended December 31, 1999 and 1998, respectively.

Customer securities - possession and control requirements

     The Company is exempt from certain provisions of Rule 15c3-3 of the

     does not otherwise hold funds or securities of customers.

Capital requirements

     The Company is subject to the Uniform Net Capital Rule (Rule 15c3-1) under
     the Securities Exchange Act of 1934, which requires that aggregate
     indebtedness (as defined) shall not exceed fifteen times net capital (as
     defined).

     Company's common stock in exchange for shares in Canaan Energy. Completion
     of the transaction is subject to several conditions, including the

To the Stockholders
Coral Reserves, Inc.
Oklahoma City, Oklahoma


     We have audited the consolidated balance sheets of Coral Reserves, Inc. as
of December 31, 1998 and 1999 and the related consolidated statements of
operations, stockholders' equity and cash flows for each of the years in the
three year period ended December 31, 1999. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 consolidated financial position of Coral Reserves,
Inc. as of December 31, 1998 and 1999, and the consolidated results of its
operations and its cash flow for each of the years in the three year period

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves, Inc. ("CRI") was formed as an Oklahoma corporation in
     December, 1989 for the sole purpose of serving as Managing General Partner
     for Coral Reserves Natural Gas Income Fund 1990 Limited Partnership ("Coral
     1990"). In addition, CRI has subsequently served as Managing General
     Partner for Coral Reserves 1993 Institutional Limited Partnership ("Coral
     1993-I") and Coral Reserves 1996 Institutional Limited Partnership ("Coral
     1996-I"). All of the aforementioned partnerships are also collectively
     referred to in these footnotes as "the Partnerships".

     By the terms of the respective partnership agreements of the Partnerships
     ("the Partnership Agreements"), revenues, costs and expenses are allocated
     to CRI as follows:

     Payout occurs on an individual limited partner basis, and is reached at the
     point in time when cumulative cash distributions made to a limited partner
     equal his or her capital contributions made to the Partnership.

     CRI is not required to make any capital contributions to the Partnership,
     unless there exists a deficit balance in their capital accounts at the time
     of termination or dissolution of the Partnership. In such case, the General
     Partners would be required to make a contribution equal to such deficit.

                         Notes to Financial Statements
                                  (Continued)

     Accounting policies employed by CRI reflect industry practices and conform
     to generally accepted accounting principles. The more significant of such
     policies are discussed below.

     The accompanying financial statements include the accounts of CRI and the
     three limited partnerships that it controls as Managing General Partner.
     All significant intercompany balances and transactions have been eliminated
     in consolidation.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, CRI considers all short-term
     debt securities purchased with a maturity of three months or less to be
     cash equivalents.

     Property and Equipment

     CRI follows the full cost method of accounting for its oil and gas
     properties. Accordingly, all costs incidental to the acquisition,
     exploration, and development of oil and gas properties, including costs of
     undeveloped leasehold, dry holes and leasehold equipment, are capitalized.
     CRI does not capitalize any internal costs as part of the full cost pool.
     Net capitalized costs (capitalized costs less accumulated amortization) are
     limited to the estimated future net revenues, discounted at 10% per annum,
     from proved oil, natural gas and natural gas liquids reserves plus the
     lower of cost or estimated fair market value of undeveloped properties
     subject to amortization. Capitalized costs less accumulated amortization
     plus estimated future development cost of proved undeveloped reserves are
     amortized by an equivalent unit-of-production method, converting natural
     gas to oil at the ratio approximating their respective energy content of
     one barrel ("Bbl") of oil to six thousand cubic feet ("Mcf") of natural
     gas. No gain or loss is recognized upon disposal of oil and gas properties
     unless such dispositions significantly alter the relationship between
     capitalized costs and proved oil and natural gas reserves.

     CRI accounts for its non-oil and natural gas long-lived assets in
     accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed

                         Notes to Financial Statements
                                  (Continued)

     for impairment whenever events or changes in circumstances indicate that
     the carrying amount of an asset may not be recoverable. Recoverability of
     assets to be held and used is measured by a comparison of the carrying
     amount of an asset to future undiscounted net cash flows expected to be
     generated by the asset. If such assets are considered to be impaired, the
     impairment to be recognized is measured by the amount by which the carrying
     amount of the assets exceeds the fair market value of the assets. Assets to
     be disposed of are reported at the lower of the carrying amount or fair
     value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, CRI receives production proceeds, from
     the purchaser and further distributes such amounts to other revenue and
     royalty owners. Production proceeds applicable to other revenue and royalty
     owners are reflected as revenue and royalty distributions payable in the
     accompanying balance sheets. CRI accrues revenue for only its net interest
     in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, CRI and other joint interest owners
     of natural gas reservoirs will take more or less than their respective
     ownership share of the natural gas volumes produced. These volumetric
     imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. CRI follows the sales method of accounting for gas
     imbalances. A liability is recorded only if CRI's excess takes of natural
     gas volumes exceeds its estimated remaining recoverable reserves. No
     receivables are recorded for those wells where CRI has taken less than its
     ownership share of gas production.

     Major Purchasers

     CRI markets its oil and natural gas production to numerous purchasers under
     a combination of short-term contracts. During 1997, 1998 and 1999 CRI's
     single largest purchaser accounted for approximately 14%, 22% and 36%,
     respectively, of its oil and natural gas revenues. CRI does not believe
     that the loss of any single customer would have a material effect on the
     results of its operations.

                                  (Continued)

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject CRI to credit risk consist
     primarily of cash and cash equivalents and trade receivables.

     CRI maintains its cash and cash equivalents with one major financial
     institution. At times, such amounts may exceed the FDIC insured limit. CRI
     has not experienced any losses in such accounts, and believes it is not
     exposed to any significant credit risk.

     Trade receivables subject CRI to the potential for credit risk with
     customers within the oil and gas industry. To reduce risk, CRI performs
     ongoing evaluations of its customers' financial condition, but does not
     generally require collateral.

2.   Accounts Receivable

     Accounts receivable consisted of the following:

3.   Notes Receivable

     Effective February 1999, one of the partnerships that is controlled by CRI
     made an advance of $2,800,000 to Indian Oil Company (Indian). In return for
     the advance, the Partnership receives a production payment payable from
     Indian in the amount of $26,250 per month.

4.   Long-Term Debt

     The balance at December 31, 1999 consists of notes payable to a bank. These
     borrowings have been made against a revolving line of credit maturing on
     April 15, 2001. The established borrowing base available to the
     Partnerships that CRI controls under these credit facilities was $3,300,000
     at December 31, 1999. Borrowings bear interest at 1% above a specified
     prime rate and are collateralized by certain oil and

     gas properties of the Partnerships, as well as guarantees by CRI and the
     Additional General Partners. The average interest rate under these credit
     facilities outstanding at December 31, 1999 was 8.15%.

5.   Income Taxes

     CRI is an S Corporation for federal and state income tax purposes. The
     items of taxable income and expense generated by its operations are
     includable in the income tax returns of the shareholders, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The CRI income tax returns, the qualifications
     of CRI as such for tax purposes, and the amount of CRI's taxable income or
     loss are subject to examination by federal and state taxing authorities. If
     such examinations resulted in changes with respect to CRI's qualification
     as an S Corporation or in changes to taxable income or loss, the tax
     liability of the shareholders could change accordingly.

6.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnerships
     engaged in certain transactions with Coral Reserves, Inc., the Managing
     General Partner of the Partnerships, and certain affiliated partnerships,
     whose Managing General Partner is Coral Reserves Energy Corp. Coral
     Reserves, Inc. and Coral Reserves Energy Corp. have common shareholders.

     The Partnerships are required to reimburse the CRI for overhead expenses,
     including office rent and salaries for clerical staff and appropriate
     production supervisory personnel, or any other overhead expenses that the
     Managing General Partner deems reasonable. The reimbursement for overhead
     expenses is limited to a maximum of five percent (5%) of "Distributable
     Cash", as defined in the Partnership Agreement. Such overhead
     reimbursements amounted to $77,716, $74,524 and $77,482 for 1997, 1998 and
     1999, respectively, and are included in "General and administrative"
     expenses in the accompanying statements of operations.

     During 1997, one of the Partnerships controlled by CRI purchased interests
     in various producing oil and natural gas properties from Coral Reserves
     Natural Gas Income Fund 1991 Limited Partnership, for aggregate

7.   Reduction of Carrying Cost of Oil and Natural Gas Properties

     Under the full cost method of accounting, the net book value of oil and
     natural gas properties may not exceed a calculated "ceiling." The ceiling
     limitation is the discounted estimated after-tax future net revenues from
     proved oil and natural gas properties. In calculating future net revenues,
     current prices and costs are generally held constant indefinitely. The net
     book value is compared to the ceiling with any

     excess written off as an expense. An expense recorded in one period may not
     be reversed in a subsequent period even though higher oil and natural gas
     prices may have increased the ceiling applicable to the subsequent period.

     At December 31, 1998, the carrying value of the Coral 1993-I and Coral
     1996-I partnerships' oil and natural gas properties exceeded the full cost
     ceiling. Accordingly, an aggregate reduction of $749,000 of the carrying
     value of such properties was recorded.

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. CRI's proved reserves were calculated by
     the independent petroleum consultants of Netherland, Sewell & Associates,
     Inc. CRI cautions that there are many uncertainties inherent in estimating
     reserve quantities, and in projecting future production rates and the
     timing of future development cost expenditures. In addition, reserve
     estimates of new discoveries are more imprecise than those of properties
     with a production history. Accordingly, these estimates are subject to
     change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the changes in proved reserves during the periods
     indicated, are set forth in the tables below. All reserves are located in
     the United States.

     CRI prepared the estimated reserves as of December 31, 1996 and 1997 based
     on geological and engineering evaluations performed as of December 31,
     1998. The reserve estimates as of the prior year-end dates were derived by
     analyzing actual historical production amounts and by adjusting the
     reserves attributable to wells acquired or disposed of during the relevant
     periods. In addition, in deriving the estimates as of December 31, 1996 and
     1997, CRI used production costs based on actual costs incurred during the
     years and actual oil and natural gas prices received on December 31, 1996
     and 1997. CRI has estimated its reserves as of December 31, 1996 and 1997
     in this manner because the actual information necessary to calculate
     estimated proved reserves and related information in accordance with
     guidelines of the SEC as of each date is not available. Because the reserve
     estimates as of December 31, 1998 are based on additional information
     gained from the result of drilling, testing and production subsequent to
     the dates of the estimated reserves, the reserve estimates as of December
     31, 1996 and 1997 are not necessarily reflective of quantities that might
     have been estimated based on information available as of such dates had
     estimates in accordance with SEC guidelines been made at such dates.
     Management believes that, because of the methodology used, the reserve
     information presented is more reflective of actual reserve quantities than
     estimates that might have been generated as of such dates.

                         INDEPENDENT AUDITOR'S REPORT



To the Stockholders
Coral Reserves Energy Corp.
Oklahoma City, Oklahoma


         We have audited the consolidated balance sheets of Coral Reserves
Energy Corp. as of December 31, 1998 and 1999 and the related consolidated
statements of operations, stockholders' equity and cash flows for each of the
years in the three year period ended December 31, 1999. 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 audits to obtain
reasonable assurance about whether the financial statements are free from
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 consolidated financial position of Coral

1.   Summary of Significant Accounting Policies

     Organization and Business Activity

     Coral Reserves Energy Corp. ("CREC") was formed as an Oklahoma corporation
     in January, 1991 for the sole purpose of serving as Managing General
     Partner for Coral Reserves Natural Gas Income Fund 1991 Limited Partnership
     ("Coral 1991"). In addition, CREC has subsequently served as Managing
     General Partner for Coral Reserves Natural Gas Income Fund 1992 Limited
     Partnership ("Coral 1992"), Coral Reserves Natural Gas Income Fund 1993
     Limited Partnership ("Coral 1993"), Coral Reserves Energy Income Fund 1995
     Limited Partnership ("Coral 1995") and Coral Reserves Energy Income Fund
     1996 Limited Partnership ("Coral 1996"). All of the aforementioned
     partnerships are also collectively referred to in these footnotes as "The
     Partnerships".

     By the terms of the Amended and Restated Agreement of Limited Partnership
     ("Partnership Agreement"), revenues, costs and expenses are allocated to
     CREC as follows:

          .    The allowance for cost depletion is allocated 99% to the Limited
               Partners and 1% to the Managing General Partner.

          .    Depreciation of lease and well equipment and amortization of
               organization costs are allocated 99% to the Limited Partners and
               1% to the Managing General Partner.

          .    All other items of income and expense, with certain limited
               exceptions, are allocated 90% to the Limited Partners and 10% to
               the General Partners until payout is achieved. After payout,
               these items are allocated 75% to the Limited Partners and 25% to
               the General Partners. Payout occurs on an individual partner
               basis, and is reached at the point in time when cash
               distributions to a Limited Partner equal his or her capital
               contributions made to the Partnership.

     The terms of the Partnership offering called for a subscription price of
     $100,000 per unit. Fractional units could be sold at the discretion of the
     Managing General Partner. Subscriptions were received for 96.350 units in
     the Partnership.

                         Notes to Financial Statements
                                  (Continued)


     The General Partners are not required to make any capital contributions to
     the Partnership, unless there exists a deficit balance in their capital
     accounts at the time of termination or dissolution of the Partnership. In
     such case, the General Partners would be required to make a contribution
     equal to such deficit.

     The Partnership is engaged primarily in the acquisition and development of
     producing oil and gas properties. These activities have occurred in the
     states of Oklahoma and Texas.

     Accounting policies employed by the Partnership reflect industry practices
     and conform to generally accepted accounting principles. The more
     significant of such policies are discussed below.

     The accompanying financial statements include the accounts of CREC and the
     five limited partnerships that it controls as Managing General Partner. All
     significant intercompany balances and transactions have been eliminated in
     consolidation.

     Uses 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
     the 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 amounts could differ from those
     estimates.

     Cash and Cash Equivalents

     For purposes of the statements of cash flows, the Partnership considers all
     short-term debt securities purchased with a maturity of three months or
     less to be cash equivalents.

     Property and Equipment

     CREC follows the full cost method of accounting for its oil and gas
     properties. Accordingly, all costs incidental to the acquisition,
     exploration, and development of oil and gas properties, including costs of
     undeveloped leasehold, dry holes and leasehold equipment, are capitalized.
     CREC does not capitalize any internal costs as part of the full cost pool.
     Net capitalized costs (capitalized costs less accumulated amortization) are
     limited to the estimated future net revenues, discounted at 10% per annum,
     from proved oil, natural gas and natural gas liquids reserves plus the
     lower of cost or estimated fair market value of undeveloped properties
     subject to amortization. Capitalized costs less accumulated amortization
     plus estimated future development cost of proved undeveloped reserves are
     amortized by an equivalent unit-of-

                         Notes to Financial Statements
                                  (Continued)


     production method, converting natural gas to oil at the ratio approximating
     their respective energy content of one barrel ("Bbl") of oil to six
     thousand cubic feet ("Mcf") of natural gas. No gain or loss is recognized
     upon disposal of oil and gas properties unless such dispositions
     significantly alter the relationship between capitalized costs and proved
     oil and natural gas reserves.

     CREC accounts for its non-oil and natural gas long-lived assets in
     accordance with the provisions of Statement of Financial Accounting
     Standards (SFAS) No. 121, "Accounting for the Impairment of Long-Lived
     Assets and Assets to be Disposed of". SFAS No. 121 requires that long-lived
     assets and identifiable intangibles be reviewed for impairment whenever
     events or changes in circumstances indicate that the carrying amount of an
     asset may not be recoverable. Recoverability of assets to be held and used
     is measured by a comparison of the carrying amount of an asset to future
     undiscounted net cash flows expected to be generated by the asset. If such
     assets are considered to be impaired, the impairment to be recognized is
     measured by the amount by which the carrying amount of the assets exceeds
     the fair market value of the assets. Assets to be disposed of are reported
     at the lower of the carrying amount or fair value less cost to sell.

     Revenue and Royalty Distributions Payable

     For certain oil and gas properties, the CREC receives production proceeds,
     from the purchaser and further distributes such amounts to other revenue
     and royalty owners. Production proceeds applicable to other revenue and
     royalty owners are reflected as revenue and royalty distributions payable
     in the accompanying balance sheets. CREC accrues revenue for only its net
     interest in its oil and natural gas properties.

     Production Costs

     Lease operating costs, including costs incurred to maintain or increase
     production levels from an existing completion interval, along with
     production related taxes are expensed as incurred.

     Gas Balancing

     During the course of normal operations, the Partnership and other joint
     interest owners of natural gas reservoirs will take more or less than their
     respective ownership share of the natural gas volumes produced. These
     volumetric imbalances are monitored over the lives of the wells' production
     capability. If an imbalance exists at the time the wells' reserves are
     depleted, cash settlements are made among the joint interest owners under a
     variety of arrangements. The Partnership follows the sales method of
     accounting for gas imbalances. A liability is recorded only if the
     Partnership's excess takes of natural gas volumes exceeds its estimated

     recoverable reserves. No receivables are recorded for those wells where the
     Partnership has taken less than its ownership share of gas production.

     Major Purchasers

     CREC markets its oil and natural gas production to numerous purchasers
     under a combination of short-term contracts. During 1997, 1998 and 1999
     CREC's single largest purchaser accounted for approximately 35%, 34% and
     32%, respectively, of its oil and natural gas revenues. CRI does not
     believe that the loss of any single customer would have a material effect
     on the results of its operations.

     Commitments and Contingencies

     Liabilities for loss contingencies arising from claims, assessments,
     litigation or other sources are recorded when it is probable that a
     liability has been incurred and the amount can be reasonably estimated.

     Concentration of Credit Risks

     Financial investments that potentially subject the Partnership to credit
     risk consist primarily of cash and cash equivalents and trade receivables.

     The Partnership maintains its cash and cash equivalents with one major
     financial institution. At times, such amounts may exceed the FDIC insured
     limit. The Partnership has not experienced any losses in such accounts, and
     believes it is not exposed to any significant credit risk.

     Trade receivables subject the Partnership to the potential for credit risk
     with customers within the oil and gas industry. To reduce risk, the
     Partnership performs ongoing evaluations of its customers' financial
     condition, but does not generally require collateral.

3.   Notes Receivable

     Effective February 1999, one of the Partnerships that is controlled by CREC
     made an advance of $3,200,000 to Indian Oil Company (Indian). In return for
     the advance, the Partnership receives a production payment payable from
     Indian in the amount of $30,000 per month.

4.   Long-Term Debt

     The balance at December 31, 1999 consists of a notes payable to a bank.
     These borrowings have been made against a revolving line of credit maturing
     on April 15, 2001. The established borrowing base available to these
     Partnerships under this credit facility was $5,375,000 at December 31,
     1999. Borrowings bear interest at 1% above a specified prime rate and are
     collateralized by certain oil and gas properties of the Partnerships, as
     well as guarantees by the Managing and Additional General Partners. The
     average interest rate under these credit facilities outstanding at December
     31, 1999 was 8.15%.

5.   Income Taxes

     CREC is an S Corporation for federal and state income tax purposes. The
     items of taxable income and expense generated by its operations are
     includable in the income tax returns of the shareholders, therefore, no
     provision or liability for federal or state income taxes is reflected in
     these financial statements. The CREC income tax returns, the qualifications
     of the CREC as such for tax purposes, and the amount of CREC's taxable
     income or loss are subject to examination by federal and state taxing
     authorities. If such examinations resulted in changes with respect to
     CREC's qualification as an S Corporation or in changes to taxable income or
     loss, the tax liability of the shareholders could change accordingly.

6.   Related Party Transactions

     During the years ended December 31, 1999, 1998 and 1997, the Partnerships
     engaged in certain transactions with Coral Reserves Energy Corp., the
     Managing General Partner of the Partnerships, and certain affiliated
     partnerships, whose Managing General Partner is Coral Reserves, Inc. Coral
     Reserves Energy Corp. and Coral Reserves, Inc. have common shareholders.

     The Partnerships are required to reimburse CREC for overhead expenses,
     including office rent and salaries for clerical staff and appropriate
     production supervisory personnel, or any other overhead expenses that the
     Managing General Partner deems reasonable. The reimbursement for overhead
     expenses is limited to a maximum of five percent (5%) of "Distributable
     Cash", as defined in the Partnership Agreement. Such overhead
     reimbursements amounted to $300,483, $252,862 and $258,016 for

     1997, 1998 and 1999, respectively, and are included in "General and
     administrative" expenses in the accompanying statements of operations.

     During 1997, Coral 1991 sold interests in various producing oil and gas
     properties to Coral 1996 and another affiliated partnership, for aggregate
     consideration of $193,246.

7.   Reduction of Carrying Cost of Oil and Natural Gas Properties

     Under the full cost method of accounting, the net book value of oil and
     natural gas properties may not exceed a calculated "ceiling." The ceiling
     limitation is the discounted estimated after-tax future net revenues from
     proved oil and natural gas properties. In calculating future net revenues,
     current prices and costs are generally held constant indefinitely. The net
     book value is compared to the ceiling with any excess written off as an
     expense. An expense recorded in one period may not be reversed in a
     subsequent period even though higher oil and natural gas prices may have
     increased the ceiling applicable to the subsequent period.

     At December 31, 1998, the carrying value of the Coral 1993 and Coral 1996
     partnerships' oil and natural gas properties exceeded the full cost
     ceiling. Accordingly, an aggregate reduction of $1,132,000 of the carrying
     value of such properties was recorded.

9.   Supplemental Information on Oil and Gas Operations (Unaudited)

     The following supplemental unaudited information regarding the oil and gas
     activities of CREC is presented pursuant to the disclosure requirements
     promulgated by the Securities and Exchange Commission and Statement of
     Financial Accounting Standards No. 69, "Disclosures About Oil and Gas
     Producing Activities".

     Quantities of Oil and Gas Reserves

     Set forth below is a summary of the changes in the net quantities of crude
     oil and natural gas and reserves for each of the years in the three-year
     period ended December 31, 1999. CREC's proved reserves were calculated by
     the independent petroleum consultants of Netherland, Sewell & Associates,
     Inc. CREC cautions that there are many uncertainties inherent in estimating
     reserve quantities, and in projecting future production rates and the
     timing of future development cost expenditures. In addition, reserve
     estimates of new discoveries are more imprecise than those of properties
     with a production history. Accordingly, these estimates are subject to
     change as additional information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
     oil, condensate, natural gas and natural liquids that geological and
     engineering data demonstrate with reasonable certainty to be recoverable in
     future years from known reservoirs under existing economic conditions.
     Proved developed oil and natural gas reserves are those reserves expected
     to be recovered through existing equipment and operating methods.

     Estimates of net quantities of proved reserves and proved developed
     reserves of crude oil, including condensate and natural gas liquids, and
     natural gas, as well as the changes in proved reserves during the periods
     indicated, are set forth in the tables below. All reserves are located in
     the United States.

                                  (Continued)


     CREC prepared the estimated reserves as of December 31, 1996 and 1997 based
     on geological and engineering evaluations performed as of December 31,
     1998. The reserve estimates as of the prior year-end dates were derived by
     analyzing actual historical production amounts and by adjusting the
     reserves attributable to wells acquired or disposed of during the relevant
     periods. In addition, in deriving the estimates as of December 31, 1996 and
     1997, CREC used production costs based on actual costs incurred during the
     years and actual oil and natural gas prices received on December 31, 1996
     and 1997. CREC has estimated its reserves as of December 31, 1996 and 1997
     in this manner because the actual information necessary to calculate
     estimated proved reserves and related information in accordance with
     guidelines of the SEC as of each date is not available. Because the reserve
     estimates as of December 31, 1998 are based on additional information
     gained from the result of drilling, testing and production subsequent to
     the dates of the estimated reserves, the reserve estimates as of December
     31, 1996 and 1997 are not necessarily reflective of quantities that might
     have been estimated based on information available as of such dates had
     estimates in accordance with SEC guidelines been made at such dates.
     Management believes that, because of the methodology used, the reserve
     information presented is more reflective of actual reserve quantities than
     estimates that might have been generated as of such dates.

    Future cash inflows are computed by applying year-end prices (averaging
    $22.75 per barrel of oil, adjusted for transportation and other charges, and
    $2.25 per Mcf of gas at December 31, 1999) to the year-end quantities of
    proved reserves, except where fixed and determinable price changes are
    provided by contractual arrangements in existence at year-end. Future
    development and production costs are computed by estimating the expenditures
    to be incurred in developing and producing proved oil and gas reserves at
    the end of the year, based on year-end costs and assuming continuation of
    existing economic conditions.

    Principal changes in the standardized measure of discounted future net cash
    flows attributable to the Partnership's proved reserves are as follows:

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION

      The following unaudited pro forma financial information has been prepared
to assist in the analysis of the financial effects of the combination
transactions involving Canaan, Indian, the General Partners, the partnerships,
and Canaan Securities. This pro forma information is based on the historical
financial statements of the entities participating in the combination
transactions.

      The information was prepared based on the following:

  .   After completion of the combination transactions, 5,000,000 Canaan common
      shares are assumed to be outstanding assuming no limited partners elect to
      receive cash in lieu of Canaan common stock. Assuming the full $15 million
      is paid to electing limited partners, there will be approximately
      3,106,938 shares outstanding after completion of the combination
      transactions. The 2,671,175 shares potentially distributable to the
      limited partners would be reduced to 778,113 if the limited partners elect
      to receive the full $15 million. For information regarding the appraised
      value of the limited partners' share of the partnerships, see Method of
      Determining Combination Exchange Values and Appraised Values elsewhere in
      this document. Canaan will borrow under its credit line the amount, if
      any, up to $15 million, to be paid to cash-electing limited partners.

  .   Canaan utilizes the full cost method of accounting for its oil and gas
      activities.

  .   The combination transactions are completed by July 31, 2000.

  .   The combination transactions are accounted for as a reorganization of
      interests under common control in a manner similar to a pooling of
      interests for the partnerships and the General Partners and as purchases
      of Indian and Canaan Securities.

  .   The unaudited pro forma balance sheet has been prepared as if the
      combination transactions occurred on March 31, 2000. The unaudited pro
      forma statement of operations and cash flows have been prepared as if the
      combination transactions occurred on January 1, 1999.

  .   Targeted annual general and administrative expense savings from the
      combination transactions have not been reflected as an adjustment to the
      historical data.

  .   Costs of the combination transactions incurred are estimated to be
      $850,000 (excluding $150,000 of transaction costs previously incurred by
      Indian) with $50,000 attributable to the acquisition of Indian, $10,000
      attributable to the acquisition of Canaan Securities and $790,000
      attributable to the combination of Canaan, the partnerships and the
      General Partners. Through March 31, 2000, Canaan has incurred and
      capitalized $545,000 of the reorganization and acquisition costs. Costs
      related to the combination transactions with the partnerships and the
      General Partners will be expensed in the period the combination
      transactions are completed. Costs related to the acquisitions of Indian
      and Canaan Securities will be capitalized as part of the purchase price.

      The unaudited pro forma financial statements and related notes are
presented for illustrative purposes only. If the combination transactions had
occurred in the past, Canaan's financial position or operating results might
have been different from those presented in the unaudited pro forma information.
The unaudited pro forma information should not be relied on as an indication of
the financial position or operating results that Canaan would have achieved if
the combination transactions had occurred as of March 31, 2000 or January 1,
1999. The unaudited pro forma information also should not be relied on as an
indication of the future results that Canaan will achieve after the completion
of the combination transactions.

              Notes to Unaudited Pro Forma Financial Information

1.   Method of Accounting for the Combination Transactions

     In presentation of the accompanying pro forma financial information, Canaan
accounted for the combination transactions as:

     .    A reorganization of entities under common control for the partnerships
          and the General Partners in a manner similar to a pooling of
          interests. Canaan does not believe the amount of cash elections
          offered in the combination transaction with the limited partners will
          be significant. See note 3 to Pro Forma Financial Information. As a
          result, the historical recorded amounts for the assets and liabilities
          of the partnerships and the General Partners were not adjusted to fair
          value and the operating results of the partnerships and the General
          Partners have been included since formation.

     .    A purchase of Indian by Canaan. Accordingly, the assets acquired and
          the liabilities assumed by Canaan were revalued and recorded at their
          estimated "fair values" and the results of operations of Indian have
          been included only since January 1, 1999.

     .    A purchase of Canaan Securities by Canaan. Accordingly, the assets
          acquired by Canaan were revalued and recorded at their estimated "fair
          values." The operations of Canaan Securities before the combination
          transactions will not continue after the combination transactions and
          Canaan Securities assets and liabilities other than its right to
          receive cash distributions from the partnerships will be distributed
          to the sole owner of Canaan Securities prior to completion of the
          combination transactions.

     .    The purchase price of the acquired net assets of Indian was based on
          the risk-adjusted, present value (using a 20% discount rate) of
          estimated future net revenues from oil and gas reserves, less the fair
          value of liabilities to be assumed by Canaan plus the fair value of
          non-oil and gas assets and working capital of Indian as of March 31,
          2000.

     .    The purchase price of the acquired net assets of Canaan Securities was
          based on the fair value of the right to receive cash distributions
          from production revenues of the partnerships. The fair value was
          determined using the same assumptions to value the oil and gas assets
          of Indian.

2.   Pro Forma Adjustments Related to the Combination Transactions

The unaudited pro forma balance sheet includes the following adjustments:

     (a)  This adjustment eliminates duplicative balances of the partnerships
          which are also included in the combined General Partners' financial
          statements. The General Partners manage and control the operations of
          the partnerships, and therefore consolidate the partnerships' assets
          and liabilities.

     (b)  This entry adjusts the historical book values of Indian's assets and
          liabilities to their estimated fair values as of March 31, 2000 and
          eliminates Indian's historical financial equity. The calculation of
          the total purchase price and the preliminary allocation to assets and
          liabilities are as follows:

          The above purchase price and allocation are as of March 31, 2000. The
          ultimate actual purchase price will be determined as of the date the
          combination transactions are completed and will be allocated to assets
          and liabilities as of that date. The fair value of Indian's oil and
          gas properties as of the date the acquisition is completed may be
          different than as of March 31, 2000 due to changes in oil and gas
          reserve quantities and estimated future prices used to value the
          reserve quantities.

          Current liabilities and other non-current liabilities being assumed by
          Canaan are less than corresponding amounts recorded by Indian by
          $84,778 and $28,259, respectively. Such amounts represent the deferred
          gain from a previous sale-leaseback transaction which does not
          obligate Canaan in the future.

          As of March 31, 2000, Canaan had incurred and capitalized $19,180 of
          Indian-related transaction costs.

          Based on relative exchange values, Indian's shareholders will receive
          1,110,500 shares of Canaan common stock which represents approximately
          22% of Canaan assuming no limited partners elect to receive cash in
          lieu of Canaan common stock.

     (c)  This adjustment records goodwill resulting from the combination
          transaction with Indian and increases deferred income taxes by $2.7
          million. This adjustment equals the deferred income tax effect of the
          difference between the fair value assigned to Indian's assets and
          liabilities and their estimated income tax basis for income tax
          purposes. Due to the tax-free nature of the combination transactions
          to the shareholders of Indian, Canaan's tax basis in those assets and
          liabilities will be the same as Indian's tax basis. Future utilization
          of Indian's tax operating loss carryforwards will be limited as a
          result of the "change of control" of Indian which will occur if the
          combination transactions are approved. The $2.7 million net deferred
          tax liability consists of tax-effected (using 38% combined federal and
          state tax rate) future taxable temporary differences of $3.3 million
          reduced by $.6 million tax-effected operating loss carryforwards of
          Indian.

                                                                    Appendix B


     (d)  This adjustment increases Canaan's oil and gas properties by $1.4
          million for the fair value of the future fees based on the
          partnerships' ongoing cash distributions from oil and gas properties
          to be received by Canaan Securities and the Placing Brokers. Even
          though Canaan is acquiring all the common stock of Canaan Securities
          in exchange for Canaan common stock, all recorded assets and
          liabilities of Canaan Securities will be distributed to the sole owner
          of Canaan Securities prior to completion of the combination
          transactions. Accordingly, the only asset being acquired by Canaan is
          the right to receive future payments based on the partnerships'
          ongoing cash distributions from oil and gas properties. The fair value
          of future payments based on cash distributions from the partnerships
          was determined in the same manner as the fair value of Indian's oil
          and gas properties. See The Combination Transactions - Description of
          the Combination Transactions elsewhere in this document. Canaan is
          acquiring the rights to receive cash distributions from the
          partnerships from the Placing Brokers in exchange for Canaan common
          stock and cash. The Placing Brokers will receive 40% of the exchange
          value in cash which approximates $390,582. This payment is in addition
          to the maximum $15 million cash option to the limited partners of the
          partnerships. See Summary - Method of Determining Combination Exchange
          Values. The owner of Canaan Securities will receive an estimated
          119,950 shares of Canaan and the Placing Brokers will receive an
          estimated 56,100 shares of Canaan which shares approximate 2.40% and
          1.14% of total Canaan shares, respectively, assuming that no limited
          partners elect to receive cash in lieu of Canaan common stock.

          This adjustment also records goodwill resulting from the combination
          transactions with Canaan Securities and increases deferred income
          taxes by $293,000. This adjustment equals the deferred income tax
          effect of the difference between the fair value assigned to Canaan
          Securities' assets and their estimated tax basis for income tax
          purposes. Due to the tax-free nature of the combination transactions
          to the shareholder of Canaan Securities, Canaan's tax basis in those
          assets will be the same as Canaan Securities' tax basis. The deferred
          tax adjustment was based on a combined federal and state tax rate of
          38%.

     (e)  This adjustment eliminates receivables and payables between Canaan,
          the General Partners and Indian. The adjustment also eliminates the
          monetary production payment receivable and payable between the General
          Partners and Indian.

     (f)  This adjustment increases Canaan's deferred income taxes for the tax
          effect of the differences between the financial carrying amounts and
          the tax bases of the partnerships' assets and liabilities at March 31,
          2000 using a combined federal and state tax rate of 38%. The
          partnerships have not recorded deferred income taxes since any tax
          liabilities are the responsibility of the individual partners. The
          $2.05 million has been excluded from the unaudited pro forma
          statements of operations as the amount will not recur and is directly
          attributable to the combination transactions. The deferred income
          taxes will be recorded as part of operations in the period in which
          the combination transactions are completed.

     (g)  This adjustment reflects expensing the deferred costs incurred by
          Canaan related to the combination transactions with the General
          Partners and the partnerships. The actual deferred costs related to
          the combination transactions with the General Partners and the
          partnerships will be expensed in the period the transactions are
          completed.

     (h)  This adjustment reflects additional compensation expense to a
          consultant of Indian (who is a proposed executive officer of Canaan)
          payable upon completion of the combination transactions.

     (i)  This adjustment records the par value ($.01) of the 5,000,000 common
          shares of Canaan which will be outstanding after completing the
          combination transactions and reclassifies the partnerships' equity to
          additional paid-in capital and accumulated deficit of Canaan. The
          adjustment assumes that no limited partners will elect to receive cash
          in lieu of Canaan common stock.

The unaudited pro forma statement of operations include the following
adjustments:

     (j)  These adjustments eliminate duplicative operations of the partnerships
          which are also included in the combined General Partners' financial
          statements. The General Partners manage and control the operations of
          the partnerships and therefore consolidate the partnerships' revenues
          and expenses.

     (k)  These adjustments eliminate oil and natural gas well overhead and
          various services charged to the partnerships as working interests
          owners in wells operated by Canaan. The overhead charges are recorded
          by Canaan as a reduction in general and administrative expenses.

     (l)  These adjustments eliminate sales commissions, consulting fees and
          investor services income, and other income of Canaan Securities
          derived from the General Partners. Canaan Securities derives all of
          its revenues from the General Partners. The adjustments also eliminate
          commission expense which will not be incurred after the combination
          transactions, and interest income resulting from the loan receivable
          from Canaan Securities' officer which is excluded from the combination
          transaction.

     (m)  These adjustments eliminate interest expense applicable to Indian's
          shareholder debt, which was contributed to Indian's equity in February
          2000.

     (n)  These adjustments record depreciation and amortization of property and
          equipment on a consolidated basis assuming the combination
          transactions were completed on January 1, 1999. The adjustments also
          record amortization of goodwill resulting from the combination
          transactions with Indian and Canaan Securities, assuming the
          transactions were completed on January 1, 1999. Goodwill amortization
          is based on the estimated life of the acquired oil and gas assets.

     (o)  This adjustment reflects additional compensation expense to a
          consultant of Indian (who is a proposed executive officer of Canaan),
          the payment of which is contingent upon the completion of the
          combination transactions. The adjustment assumes the combination
          transactions were completed on January 1, 1999.

     (p)  These adjustments record the net tax effect of all pro forma
          adjustments at a combined statutory federal and state tax rate of 38%
          after consideration of permanent differences. The adjustments include
          income taxes for the applicable period for the partnerships for which
          no income taxes have been previously recorded.

     (q)  This adjustment records estimated transaction costs net of income tax
          of $300,000 (using a 38% effective tax rate) related to the
          combination of the General Partners and the partnerships, assuming the
          combination transactions were completed on January 1, 1999. Total
          combination transaction costs are expected to be $790,000.

The unaudited pro forma statements of cash flows include the following
adjustments:

     (r)  These adjustments eliminate the cash flows of the partnerships, which
          are also included in the combined general partners' financial
          statements. The General Partners manage and control the operations of
          the partnerships, and therefore consolidate the partnerships' cash
          flows.

     (s)  These adjustments reflect the net adjustments to the pro forma
          statement of operations and reflect pro forma adjustments effecting
          the reconciliation of net earnings to net cash provided by operating
          activities.

     (t)  This adjustment reflects the acquisition of Indian's cash, assuming
          the transaction was completed on January 1, 1999. The adjustment also
          reflects the $390,528 Canaan will pay in acquiring the Placing
          Brokers' rights to receive cash distributions from the partnerships
          (see adjustment (d)).

     (u)  This adjustment eliminates the advances/borrowings and repayments
          related to the monetary production payment receivable and payable
          between the General Partners and Indian.

     (v)  These adjustments eliminate Canaan Securities' beginning historical
          cash balances, and historical net cash provided (used in) operating
          and investing activities. Canaan Securities' assets are excluded from
          the acquisition, and its liabilities are not being assumed (see
          adjustment (d)).

     (w)  These adjustments reflect the change in deferred income taxes,
          resulting from pro forma adjustments effecting the differences between
          financial carrying amounts and the tax bases of the combination
          entities.

     (x)  This adjustment eliminates the historical deferred transaction costs
          related to the combination with the General Partners and the limited
          partners to reflect the expensing of such costs.

3.   Pro Forma Effect of Cash Offer to Limited Partners

     A limited partner may elect to receive cash in lieu of Canaan common stock
in an amount equal to the appraisal value of his partnership interest based on
an independent appraisal of the partnership assets. See Summary - Determination
of Appraised Value. There is a limit of $15 million on the amount of cash
payable to electing limited partners.

     The pro forma financial information has been prepared based on no limited
partners electing to receive cash.  Accordingly, the combination of the
partnerships and Canaan has been accounted for as a reorganization of interests
under common control in a manner similar to a pooling of interests.

     If the limited partners elect to receive the full $15 million,
approximately 71% of the limited partners interests in the partnerships will be
purchased for cash. While Canaan does not expect to purchase a significant
portion of the limited partner interests for cash, a payment of $15 million
would likely require the combination of Canaan and the partnerships to be
accounted for as a purchase of the limited partners interests rather than as a
reorganization of interests under common control.

     However, the net book of the partnerships' oil and gas properties as
reflected on the accompanying pro forma balance sheet as of March 31, 2000 does
not differ materially from the fair value of such properties. Accordingly, the
differences resulting from different accounting treatment of the combination of
Canaan and the partnerships under reorganization accounting or purchase
accounting would not materially affect the pro forma balance sheet of Canaan as
of March 31, 2000.

     Assuming Canaan borrows the entire $15 million (at 8.75%) for the purchase
of electing-limited partners' partnership interests, the effect on the
accompanying pro forma statements of operations would be as follows:

4.   Pro Forma Outstanding Shares of Canaan

     A total of 5,000,000 shares of Canaan common stock will be issued and be
outstanding after the combination transactions, less the number of shares
otherwise issuable to the limited partners who elect to receive cash. The owners
of each of the participating entities will receive shares of Canaan common stock
in proportion to the "Exchange Value" of each entity to the total Exchange Value
of all entities. The Exchange Value has been determined by Canaan and is based
on a valuation of each entity's oil and gas reserves and other assets and
liabilities. Any limited partner in any partnership may elect to receive cash in
lieu of Canaan common stock equal to the appraisal value of his interest in a
partnership.

     The number of shares to be received by each participating entity, assuming
no limited partner elects to receive cash in lieu of Canaan common stock, is
reflected in the table on page 16 under the heading Canaan Common Stock - Number
of Shares.

     Assuming the full $15 million is paid to electing partners, there will be
3,106,938 shares outstanding after completion of the combination transactions.
The 2,671,175 shares potentially distributable to the limited partners would be
reduced to 778,113 if the limited partners elect to receive the full $15
million. For every $100,000 of cash paid to electing limited partners, the
number of shares otherwise distributable to limited

partners decreases by 12,620 or approximately .5% of the total shares
distributable to the limited partners. To effect a 1% decrease in the total
shares expected to be outstanding after completion of the combination
transactions, limited partners would have to elect to receive an aggregate of
approximately $396,000 which is 1.9% of the total appraised value of all the
partnerships.

5.   Pro Forma Oil and Gas Property Acquisition and Development Activities

     The pro forma oil and gas property acquisition and development activities
set forth below assumes the combination transactions were completed on January
1, 1999. The pro forma adjustments reflect the estimated fair value of the oil
and gas assets purchased from Indian, and the estimated fair value of Canaan
Securities' and the Placing Brokers' future payments from the partnerships'
ongoing cash distributions from oil and gas properties.

6.   Pro Forma Information on Oil and Gas Operations

     The pro forma reserve information set forth below assumes the combination
transactions were completed on January 1, 1999. Since the General Partners
consolidate the assets, liabilities, revenues and expenses of the partnerships
for financial reporting purposes, the partnerships' reserve quantities and the
standardized measure of discounted future net cash flows of the partnerships are
included in the column for the General Partners. There are many uncertainties
inherent in estimating reserve quantities, and in projecting future production
rates and the timing of future development expenditures. In addition, reserve
estimates of new discoveries are more imprecise than those of properties with a
production history. Accordingly, estimates are subject to change as additional
information becomes available.

     Proved oil and natural gas reserves are the estimated quantities of crude
oil, condensate, natural gas and natural gas liquids that geological and
engineering data demonstrate with reasonable certainty to be recoverable in
future years from known reservoirs under existing economic conditions. Proved
developed oil and natural gas reserves are those reserves expected to be
recovered through existing equipment and operating methods.

     All reserves are located in the United States.

     The pro forma adjustment to standardized measure and changes in
standardized measure of discounted future net cash flows reflects the purchase
of Indian's oil and gas reserves, assuming the combination transactions were
completed on January 1, 1999. The adjustment also reflects the future income tax
expense impact on the General Partners' standardized measure and changes in
standardized measure of discounted future net cash flows using a combined
federal and state tax rate of 38%. Future income tax expense has been excluded
from the General Partners' standardized measure and changes in standardized
measure of discounted future net cash flows since any tax liabilities are the
responsibility of the individual partners.

               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities".  When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers.  A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash.  The owners of each of the
Combining
<PAGE>

Entities will receive shares of Canaan common stock in proportion to the
"Exchange Value" of such entity relative to the total Exchange Value of all
Combining Entities. The Exchange Value was determined by Canaan and is based on
a valuation of each Combining Entity's oil and gas Reserve Values and other
assets and liabilities. The Reserves Values were determined by Netherland,
Sewell & Associates, Inc. an independent petroleum engineering and consulting
firm, using the same price, cost, effective date and discount rate assumptions
for each entity. A limited partner in any partnership may also elect to receive
cash in lieu of Canaan common stock equal to the "Appraised Value" of his
interest in the partnership.

          The Prospectus/Proxy Statement dated ___________, 2000, which we refer
to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions.  This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1990
Partnership.  The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.


                                 RISK FACTORS

                               TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .    No gain or loss will be recognized by a limited partner as a
               result of the receipt of Canaan common stock in connection with
               the combination transactions.

          .    The basis of the Canaan common stock received by each limited
               partner will be equal to the basis of his partnership interest
               exchanged for such stock.

          .    The holding period for the Canaan common stock for purposes of
               computing eligibility for long-term capital gain or loss will
               include the period of a limited partner's ownership of his
               partnership interest exchanged for such stock and, to the extent
               the Canaan common stock received is attributable to certain
               ordinary income assets of the partnership, may begin on the day
               after the closing of the combination transactions.

          .    A limited partner who receives cash will recognize gain or loss
               equal to the difference between the cash received and his
               adjusted tax basis of his limited partnership interest on the
               date of the closing of the combination transactions. Gain
               recognized by a limited partner will be capital except to the
               extent of such limited partner's share of ordinary income assets,
               including recapture of depletion, depreciation and intangible
               drilling cost deductions previously allocated to a limited
               partner.

            METHOD OF DETERMINING COMBINATION EXCHANGE VALUES AND
                               APPRAISED VALUES

          The following is a summary of the methods of determining the Exchange
Values and Appraised Values.  For more detailed information concerning the

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities.  The Exchange Value takes into consideration the
value of each Combining Entities oil and gas reserves determined as described
below and the other assets and liabilities of each Combining Entity as adjusted
for other items for Canaan, Indian and the 1996 and 1996-I partnerships.  The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values.  This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity.  The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity.  Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999.  We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers.  However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties.  The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

                                      -4-
<PAGE>

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.

          .    For Canaan, an upward adjustment of $5.0 million for the value of
               its "operating rights" as described in the Prospectus.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for the Indian Contingent
               Production Payment as described in the Prospectus.


Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared.  In each of the partnerships except 1993-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner.  Accordingly, in
each of those partnerships in which payout has not already occurred as to all
limited partners as of the Effective Date, the Reserve Value was allocated first
among the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          As of March 31, 2000, "payout" had occurred for all limited partners
in the 1990 Partnership.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues.  In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date.  This allocation will be made prior
to the allocation of the remaining Reserve Value and other components of
Exchange Value to the limited partners and the General Partners.

                                      -5-
<PAGE>

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships.  Accordingly, the Exchange Value allocated to the General Partner
in these partnerships will be reduced to take into consideration the amount of
the Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share.  The Placing Brokers will receive cash equal to the 40% of
their Exchange Value and their share of Canaan common stock will be determined
based on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership.  The Appraised Value was determined
based on an appraisal by Madison Energy Advisors of each partnership's oil and
gas properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values.  The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes  the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership.  The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership.  The Appraised
Value for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount.  Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

                                      -6-

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1990 Partnership and Table B for the calculation of the Appraised Value
of the 1990 Partnership.


                   FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions.  The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values.  The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations.  By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest.  This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

                  INFORMATION CONCERNING THE 1990 PARTNERSHIP

General
          The 1990 Partnership was formed in April, 1990 and raised $3.9 million
of limited partner capital contributions.  As of March 31, 2000, the 1990
Partnership had distributed $5.5 million in cash to limited partners
representing 143% of their original investment.  The 1990 Partnership has
achieved payout for all limited partners.

          The term of the 1990 Partnership is until December 31, 2009 unless the
partnership is earlier terminated in accordance with the applicable provisions
of the Partnership Agreement.

                                      -7-

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1990 Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1990 Partnership
will continue in its business as previously conducted.  However, it is possible
a new transaction might be provoked by Canaan or the General Partners, but no
other terms have been discussed or considered by them.  In addition, Canaan and
the General Partners may also explore other alternatives, such as the sale of
the Coral Group to a third party, but there is no assurance that Canaan and the
General Partners could find a third party interested in purchasing as such.  The
terms and conditions of any such purchase and sale agreement would be as
favorable as the terms offered pursuant to the combination transactions.

          As of December 31, 1999, the 1990 Partnership had bank indebtedness of
$690,455 which is equal to 39% of the Present Value of its oil and gas reserves.
If the combination transactions are not approved, the General Partners
anticipate that amortization of such bank debt will begin prior to year end 2000
and such amortization will have an adverse affect on limited partner cash
distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1990 Partnership is $25,500 of which a maximum of $19,125 would be allocated
to limited partners if all limited partners voted in favor of the combination
transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was continued.  This value is referred to as the
"Continuation Value" and is based on the following assumptions:

          .  The estimated future net revenues from the sale of oil and gas are
             based on the same prices and costs that are used to estimate the
             Reserve Value for purposes of the Exchange Value.

          .  The partnerships will continue to incur general administrative
             expenses in favor of the General Partners as provided in the
             applicable partnership agreement in the amount of 5% of the amount
             of distributable cash.

          .  Any partnership with bank debt is assumed to amortize such debt on
             a 36 month level amortization basis, assuming an interest rate of
             9%, beginning July 31, 2000.

                                      -8-
<PAGE>

          .    The estimated future net cash flows have been discounted at a
               discount rate of 10% to arrive at the estimated Continuation
               Value.

Appraised Value and Continuation Value for the 1990 Partnership

                    Calculation of Estimated Exchange Value

          The Exchange Value is estimated based on Canaan's estimate of cash
distributions and interest expense from the September 30, 1999 Effective Date to
an assumed closing date of July 31, 2000.  Variances in actual cash
distributions and interest expense or a change in the closing date will result
in a change in the Exchange Value for the partnership and will similarly change
Exchange Values for other Combining Entities.

                           1990 Limited Partnership

                   Calculation of Estimated Appraised Value

          The Appraised Value is estimated based on Canaan's estimate of
property net revenue from the September 30, 1999 Effective Date to an assumed
closing date of July 31, 2000. Variances in actual net revenue or a change in
the closing date will result in a change in the Appraised Value for the
partnership and will similarly change Appraised Values for other partnerships.
Property net revenues include proceeds from sale of production less production
taxes and operating expense.

             The date of this Supplement is _______________, 2000

General

          This Supplement relates to the proposed "combination transactions"
involving Canaan Energy Corporation. In the proposed combination transactions:

          .    Canaan will acquire all of the limited partners' and Additional
               General Partners' interests in the eight oil and gas limited
               partnerships previously sponsored by Coral Reserves, Inc. and
               Coral Reserves Energy Corp., affiliates of Canaan and the General
               Partners of the partnerships;

          .    Canaan will acquire 100% of the stock of the General Partners of
               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities". When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers. A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash. The owners of each of the
Combining Entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of
<PAGE>

such entity relative to the total Exchange Value of all Combining Entities. The
Exchange Value was determined by Canaan and is based on a valuation of each
Combining Entity's oil and gas Reserve Value and other assets and liabilities.
The Reserves Values were determined by Netherland, Sewell & Associates, Inc. an
independent petroleum engineering and consulting firm, using the same price,
cost, effective date and discount rate assumptions for each entity. A limited
partner in any partnership may also elect to receive cash in lieu of Canaan
common stock equal to the "Appraised Value" of his interest in the partnership.

          The Prospectus/Proxy Statement dated ___________, 2000, which we refer
to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions. This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1991
Partnership. The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.

                                 RISK FACTORS

          There are numerous risks associated with the combination transactions.
For a more complete description of these risk factors, please see:

          .   "Risk Factors and Material Considerations" beginning on page 30 of
              the Prospectus.

          .   "Comparison of Securityholder Rights" beginning on page 156 of the
              Prospectus.

Risks Related to the 1991 Partnership

          There are no risk factors applicable to the 1991 Partnership that are
materially different from the risk factors described in the Prospectus.

                               TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .   No gain or loss will be recognized by a limited partner as a
              result of the receipt of Canaan common stock in connection with
              the combination transactions.

          .   The basis of the Canaan common stock received by each limited
              partner will be equal to the basis of his partnership interest
              exchanged for such stock.

          .   The holding period for the Canaan common stock for purposes of
              computing eligibility for long-term capital gain or loss will
              include the period of a limited partner's ownership of his
              partnership interest exchanged for such stock and, to the extent
              the Canaan common stock received is attributable to certain
              ordinary income assets of the partnership, may begin on the day
              after the closing of the combination transactions.

          .   A limited partner who receives cash will recognize gain or loss
              equal to the difference between the cash received and his adjusted
              tax basis of his limited partnership interest on the date of the
              closing of the combination transactions. Gain recognized by a
              limited partner will be capital except to the extent of such
              limited partner's share of ordinary income assets, including
              recapture of depletion, depreciation and intangible drilling cost
              deductions previously allocated to a limited partner.

              the Prospectus.

     METHOD OF DETERMINING COMBINATION EXCHANGE VALUES AND APPRAISED VALUES

          The following is a summary of the methods of determining the Exchange
Values and Appraised Values. For more detailed information concerning the
subject, please see the following sections of the Prospectus:

              Values" on page 62.

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities. The Exchange Value takes into consideration the value
of each Combining Entities oil and gas reserves determined as described below
and the other assets and liabilities of each Combining Entity as adjusted for
other items for Canaan, Indian and the 1996 and 1996-I partnerships. The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values. This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity. The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity. Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999. We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers. However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties. The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .   Reserve Value as of the Effective Date.

          .   Less bank debt at the closing date.

                                      -4-
<PAGE>

          .   Minus interest paid or accrued on bank or other debt assumed by
              Canaan from the Effective Date to the closing date.

          .   For limited partners, Additional General Partners, Canaan
              Securities and Placing Brokers, minus their share of cash
              distributions from production subsequent to the Effective Date and
              before the closing date.

          .   An adjustment for any gas imbalances which are not expected to be
              material.

          .   For Canaan, an upward adjustment of $5.0 million for the value of
              its "operating rights" as described in the Prospectus.

          .   For the 1996 and 1996-I Partnerships, upward adjustments, and for
              Indian, a downward adjustment, for the Indian Contingent
              Production Payment as described in the Prospectus.

Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared. In each of the partnerships except 1993-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner. Accordingly, in each
of those partnerships in which payout has not already occurred as to all limited
partners as of the Effective Date, the Reserve Value was allocated first among
the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          As of March 31, 2000, "payout" had occurred for all limited partners
in the 1991 Partnership.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues. In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date. This allocation will be made prior
to the allocation of the remaining Reserve Value and other components of
Exchange Value to the limited partners and the General Partners.

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships. Accordingly, the Exchange Value allocated to the General Partner
in these partnerships will be reduced to take into consideration the amount of
the Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share. The Placing Brokers will receive cash equal to the 40% of their
Exchange Value and their share of Canaan common stock will be determined based
on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership. The Appraised Value was determined based
on an appraisal by Madison Energy Advisors of each partnership's oil and gas
properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values. The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership. The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership. The Appraised Value
for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount. Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1991 Partnership and Table B for the calculation of the Appraised Value
of the 1991 Partnership.

                   FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions. The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values. The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations. By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest. This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

                  INFORMATION CONCERNING THE 1991 PARTNERSHIP

General

          The 1991 Partnership was formed in April, 1991 and raised $4.5 million
of limited partner capital contributions. As of March 31, 2000, the 1991
Partnership had distributed $6.5 million in cash to limited partners
representing 144% of their original investment. The 1991 Partnership has
achieved payout for all limited partners.

          The term of the 1991 Partnership is until December 31, 2010 unless the
partnership is earlier terminated in accordance with the applicable provisions
of the Partnership Agreement.

                                      -7-
<PAGE>

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1991 Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1991 Partnership
will continue in its business as previously conducted.  However, it is possible
a new transaction might be provoked by Canaan or the General Partners, but no
other terms have been discussed or considered by them.  In addition, Canaan and
the General Partners may also explore other alternatives, such as the sale of
the Coral Group to a third party, but there is no assurance that Canaan and the
General Partners could find a third party interested in purchasing as such.  The
terms and conditions of any such purchase and sale agreement would be as
favorable as the terms offered pursuant to the combination transactions.

          As of December 31, 1999, the 1991 Partnership had bank indebtedness of
$742,734 which is equal to 32% of the Present Value of its oil and gas reserves.
If the combination transactions are not approved, the General Partners
anticipate that amortization of such bank debt will begin prior to year end 2000
and such amortization will have an adverse affect on limited partner cash
distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1991 Partnership is $34,000 of which a maximum of $25,500 would be allocated
to limited partners if all limited partners voted in favor of the combination
transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was continued.  This value is referred to as the
"Continuation Value" and is based on the following assumptions:

          .  The estimated future net revenues from the sale of oil and gas are
             based on the same prices and costs that are used to estimate the
             Reserve Value for purposes of the Exchange Value.

          .  The partnerships will continue to incur general administrative
             expenses in favor of the General Partners as provided in the
             applicable partnership agreement in the amount of 5% of the amount
             of distributable cash.

          .  Any partnership with bank debt is assumed to amortize such debt on
             a 36 month level amortization basis, assuming an interest rate of
             9%, beginning July 31, 2000.

                                      -8-
<PAGE>

          .   The estimated future net cash flows have been discounted at a
              discount rate of 10% to arrive at the estimated Continuation
              Value.

          Table E in this Supplement provides a comparison of Exchange Value,
Appraised Value and Continuation Value for the 1991 Partnership

                    Calculation of Estimated Exchange Value

          The Exchange Value is estimated based on Canaan's estimate of cash
distributions and interest expense from the September 30, 1999 Effective Date to
an assumed closing date of July 31, 2000. Variances in actual cash distributions
and interest expense or a change in the closing date will result in a change in
the Exchange Value for the partnership and will similarly change Exchange Values
for other Combining Entities.

(1)  Because of depletion (which is usually higher in the early years of
     production), a portion of every distribution of revenues from properties
     represents a return of a limited partner's original investment. Until a
     limited partner receives cash distributions equal to his original
     investment, 100% of such distributions may be deemed to be a return of
     capital.

          The Exchange Value does not represent the fair value of the
partnership or its net assets and is being used solely for purposes of
determining the relative ownership of Canaan by the 1991 Partnership. There is
no assurance that the value of common stock received by a limited partner will
be equal to Exchange Value. The Appraised Value is the amount a limited partner
may elect to receive in cash and is based on an appraisal of the partnership's
assets and an assumed liquidation of the 1991 Partnership.

             The date of this Supplement is _______________, 2000

General

          This Supplement relates to the proposed "combination transactions"
involving Canaan Energy Corporation.  In the proposed combination transactions:

          .    Canaan will acquire all of the limited partners' and Additional
               General Partners' interests in the eight oil and gas limited
               partnerships previously sponsored by Coral Reserves, Inc. and
               Coral Reserves Energy Corp., affiliates of Canaan and the General
               Partners of the partnerships;

          .    Canaan will acquire 100% of the stock of the General Partners of
               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities".  When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers.  A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash.  The owners of each of the
Combining Entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of
<PAGE>

such entity relative to the total Exchange Value of all Combining Entities. The
Exchange Value was determined by Canaan and is based on a valuation of each
Combining Entity's oil and gas Reserve Values and other assets and liabilities.
The Reserves Values were determined by Netherland, Sewell & Associates, Inc. an
independent petroleum engineering and consulting firm, using the same price,
cost, effective date and discount rate assumptions for each entity. A limited
partner in any partnership may also elect to receive cash in lieu of Canaan
common stock equal to the "Appraised Value" of his interest in the partnership.

          The Prospectus/Proxy Statement dated __________, 2000, which we refer
to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions.  This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1992
Partnership.  The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.


                                 RISK FACTORS

          There are numerous risks associated with the combination transactions.
For a more complete description of these risk factors, please see:

               the Prospectus.


 Risks Related to the 1992 Partnership

          There are no risk factors applicable to the 1992 Partnership that are
materially different from the risk factors described in the Prospectus.

                               TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .    No gain or loss will be recognized by a limited partner as a
               result of the receipt of Canaan common stock in connection with
               the combination transactions.

          .    The basis of the Canaan common stock received by each limited
               partner will be equal to the basis of his partnership interest
               exchanged for such stock.

          .    The holding period for the Canaan common stock for purposes of
               computing eligibility for long-term capital gain or loss will
               include the period of a limited partner's ownership of his
               partnership interest exchanged for such stock and, to the extent
               the Canaan common stock received is attributable to certain
               ordinary income assets of the partnership, may begin on the day
               after the closing of the combination transactions.

          .    A limited partner who receives cash will recognize gain or loss
               equal to the difference between the cash received and his
               adjusted tax basis of his limited partnership interest on the
               date of the closing of the combination transactions. Gain
               recognized by a limited partner will be capital except to the
               extent of such limited partner's share of ordinary income assets,
               including recapture of depletion, depreciation and intangible
               drilling cost deductions previously allocated to a limited
               partner.

    METHOD OF DETERMINING COMBINATION EXCHANGE VALUES AND APPRAISED VALUES

          The following is a summary of the methods of determining the Exchange
Values and Appraised Values. For more detailed information concerning the
subject, please see the following sections of the Prospectus:

               page 8.

               Values" on page 62.

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities.  The Exchange Value takes into consideration the
value of each Combining Entities oil and gas reserves determined as described
below and the other assets and liabilities of each Combining Entity as adjusted
for other items for Canaan, Indian and the 1996 and 1996-I partnerships.  The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values.  This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity.  The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity.  Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999.  We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers.  However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties.  The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

                                      -4-
<PAGE>

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.

          .    For Canaan, an upward adjustment of $5.0 million for the value of
               its "operating rights" as described in the Prospectus.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for the Indian Contingent
               Production Payment as described in the Prospectus.


Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared. In each of the partnerships except 1993-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner. Accordingly, in each
of those partnerships in which payout has not already occurred as to all limited
partners as of the Effective Date, the Reserve Value was allocated first among
the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          As of March 31, 2000, "payout" had occurred for some but not all
limited partners in the 1992 Partnership.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues.  In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date.  This allocation will be made prior
to the allocation of the remaining Reserve Value and other components of
Exchange Value to the limited partners and the General Partners.

                                      -5-
<PAGE>

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships. Accordingly, the Exchange Value allocated to the General Partner
in these partnerships will be reduced to take into consideration the amount of
the Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share. The Placing Brokers will receive cash equal to the 40% of their
Exchange Value and their share of Canaan common stock will be determined based
on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership. The Appraised Value was determined based
on an appraisal by Madison Energy Advisors of each partnership's oil and gas
properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values. The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership. The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership. The Appraised Value
for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount.  Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

                                      -6-

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1992 Partnership and Table B for the calculation of the Appraised Value
of the 1992 Partnership.


                   FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions.  The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values. The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations. By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest. This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

                  INFORMATION CONCERNING THE 1992 PARTNERSHIP

General

          The 1992 Partnership was formed in June, 1992 and raised $7.5 million
of limited partner capital contributions.  As of March 31, 2000, the 1992
Partnership had distributed $7.2 million in cash to limited partners
representing 97% of their original investment.  The 1992 Partnership has
achieved payout for some limited partners but not all.

          The term of the 1992 Partnership is until December 31, 2011 unless the
partnership is earlier terminated in accordance with the applicable provisions
of the Partnership Agreement.

                                      -7-
<PAGE>

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1992 Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1992 Partnership
will continue in its business as previously conducted.  However, it is possible
a new transaction might be provoked by Canaan or the General Partners, but no
other terms have been discussed or considered by them.  In addition, Canaan and
the General Partners may also explore other alternatives, such as the sale of
the Coral Group to a third party, but there is no assurance that Canaan and the
General Partners could find a third party interested in purchasing as such.  The
terms and conditions of any such purchase and sale agreement would be as
favorable as the terms offered pursuant to the combination transactions.

          As of December 31, 1999, the 1992 Partnership had bank indebtedness of
$589,000 which is equal to 11% of the Present Value of its oil and gas reserves.
If the combination transactions are not approved, the General Partners
anticipate that amortization of such bank debt will begin prior to year end 2000
and such amortization will have an adverse affect on limited partner cash
distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1992 Partnership is $93,500 of which a maximum of $84,150 would be allocated
to limited partners if all limited partners voted in favor of the combination
transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was continued.  This value is referred to as the
"Continuation Value" and is based on the following assumptions:

          .  The estimated future net revenues from the sale of oil and gas are
             based on the same prices and costs that are used to estimate the
             Reserve Value for purposes of the Exchange Value.

          .  The partnerships will continue to incur general administrative
             expenses in favor of the General Partners as provided in the
             applicable partnership agreement in the amount of 5% of the amount
             of distributable cash.

          .  Any partnership with bank debt is assumed to amortize such debt on
             a 36 month level amortization basis, assuming an interest rate of
             9%, beginning July 31, 2000.

                                      -8-
<PAGE>

          .    The estimated future net cash flows have been discounted at a
               discount rate of 10% to arrive at the estimated Continuation
               Value.

                           1992 Limited Partnership

                    Calculation of Estimated Exchange Value


          The Exchange Value is estimated based on Canaan's estimate of cash
distributions and interest expense from the September 30, 1999 Effective Date to
an assumed closing date of July 31, 2000.  Variances in actual cash
distributions and interest expense or a change in the closing date will result
in a change in the Exchange Value for the partnership and will similarly change
Exchange Values for other Combining Entities.

     Determining Combination Exchange Values and Appraised Values" in the
     Prospectus.  No partnerships own an individual property representing more
     than 10% of the Reserve Value or from which the partnership derived more
     than 10% of its cash flow or net income for the year ended December 31,
     1999.

(2)  Assumes no limited partners elect to receive cash.  Placing Brokers' shares
     based on 60% of Exchange Value.

(3)  Assumes closing on July 31, 2000, and uses Netherland, Sewell reserve
     report to estimate property revenues and expenses and estimated interest
     rate on bank debt for purposes of calculating interest expense.

(4)  The "Estimated Exchange Value at Closing" for all of the partnerships and
     Canaan set forth in the table is approximately 96.3% of the sum of their
     respective components of Exchange Value because the operating rights
     adjustment to Canaan's Exchange Value within the Coral Group is excluded
     for purposes of computing the relative Exchange Value between the Coral
     Group and Indian.  See "Method of Determining Combination Exchange Values
     and Appraised Values" in the Prospectus for a more detailed explantation.

                           1992 Limited Partnership

                   Calculation of Estimated Appraised Value


          The Appraised Value is estimated based on Canaan's estimate of
property net revenue from the September 30, 1999 Effective Date to an assumed
closing date of July 31, 2000. Variances in actual net revenue or a change in
the closing date will result in a change in the Appraised Value for the
partnership and will similarly change Appraised Values for other partnerships.
Property net revenues include proceeds from sale of production less production
taxes and operating expense.

(1)  Because of depletion (which is usually higher in the early years of
     production), a portion of every distribution of revenues from properties
     represents a return of a limited partner's original investment. Until a
     limited partner receives cash distributions equal to his original
     investment, 100% of such distributions may be deemed to be a return of
     capital.

          The Exchange Value does not represent the fair value of the
partnership or its net assets and is being used solely for purposes of
determining the relative ownership of Canaan by the 1992 Partnership.  There is
no assurance that the value of common stock received by a limited partner will
be equal to Exchange Value.  The Appraised Value is the amount a limited partner
may elect to receive in cash and is based on an appraisal of the partnership's
assets and an assumed liquidation of the 1992 Partnership.

General

          This Supplement relates to the proposed "combination transactions"
involving Canaan Energy Corporation. In the proposed combination transactions:

          .    Canaan will acquire all of the limited partners' and Additional
               General Partners' interests in the eight oil and gas limited
               partnerships previously sponsored by Coral Reserves, Inc. and
               Coral Reserves Energy Corp., affiliates of Canaan and the General
               Partners of the partnerships;

          .    Canaan will acquire 100% of the stock of the General Partners of
               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities". When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers. A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash. The owners of each of the
Combining Entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of
<PAGE>

such entity relative to the total Exchange Value of all Combining Entities. The
Exchange Value was determined by Canaan and is based on a valuation of each
Combining Entity's oil and gas Reserve Values and other assets and liabilities.
The Reserves Values were determined by Netherland, Sewell & Associates, Inc. an
independent petroleum engineering and consulting firm, using the same price,
cost, effective date and discount rate assumptions for each entity. A limited
partner in any partnership may also elect to receive cash in lieu of Canaan
common stock equal to the "Appraised Value" of his interest in the partnership.

          The Prospectus/Proxy Statement dated _________, 2000, which we refer
to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions. This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1993-I
Partnership. The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.


                                 RISK FACTORS

          There are numerous risks associated with the combination transactions.
For a more complete description of these risk factors, please see:

          .    "Risk Factors and Material Considerations" beginning on page 30
               of the Prospectus.

          .    "Comparison of Securityholder Rights" beginning on page 156 of
               the Prospectus.


 Risks Related to the 1993-I Partnership

          There are no risk factors applicable to the 1993-I Partnership that
are materially different from the risk factors described in the Prospectus.

                               TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .    No gain or loss will be recognized by a limited partner as a
               result of the receipt of Canaan common stock in connection with
               the combination transactions.

          .    The basis of the Canaan common stock received by each limited
               partner will be equal to the basis of his partnership interest
               exchanged for such stock.

          .    The holding period for the Canaan common stock for purposes of
               computing eligibility for long-term capital gain or loss will
               include the period of a limited partner's ownership of his

               the Canaan common stock received is attributable to certain
               ordinary income assets of the partnership, may begin on the day
               after the closing of the combination transactions.

               date of the closing of the combination transactions. Gain
               recognized by a limited partner will be capital except to the
               extent of such limited partner's share of ordinary income assets,
               including recapture of depletion, depreciation and intangible

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities. The Exchange Value takes into consideration the value
of each Combining Entities oil and gas reserves determined as described below
and the other assets and liabilities of each Combining Entity as adjusted for
other items for Canaan, Indian and the 1996 and 1996-I partnerships. The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values. This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity. The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity. Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999. We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers. However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties. The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

                                      -4-
<PAGE>

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.

          .    For Canaan, an upward adjustment of $5.0 million for the value of
               its "operating rights" as described in the Prospectus.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for the Indian Contingent
               Production Payment as described in the Prospectus.


Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared. In each of the partnerships except 1993-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner. Accordingly, in each
of those partnerships in which payout has not already occurred as to all limited
partners as of the Effective Date, the Reserve Value was allocated first among
the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues. In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date. This allocation will be made prior
to the allocation of the remaining Reserve Value and other components of
Exchange Value to the limited partners and the General Partners.

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships. Accordingly, the Exchange Value allocated to the General Partner
in these

                                      -5-
<PAGE>

partnerships will be reduced to take into consideration the amount of the
Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share. The Placing Brokers will receive cash equal to the 40% of their
Exchange Value and their share of Canaan common stock will be determined based
on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership. The Appraised Value was determined based
on an appraisal by Madison Energy Advisors of each partnership's oil and gas
properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values. The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership. The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership. The Appraised Value
for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount. Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

<PAGE>

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1993-I Partnership and Table B for the calculation of the Appraised Value
of the 1993-I Partnership.


                   FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions. The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values. The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations. By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest. This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

                 INFORMATION CONCERNING THE 1993-I PARTNERSHIP

General
          The 1993-I Partnership was formed in September, 1993 and raised $2.4
million of limited partner capital contributions. As of March 31, 2000, the
1993-I Partnership had distributed $2.6 million in cash to limited partners
representing 112% of their original investment.

          The term of the 1993-I Partnership is until December 31, 2012 unless
the partnership is earlier terminated in accordance with the applicable
provisions of the Partnership Agreement.

                                      -7-
<PAGE>

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1993 Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1993 Partnership
will continue in its business as previously conducted.  However, it is possible
a new transaction might be provoked by Canaan or the General Partners, but no
other terms have been discussed or considered by them.  In addition, Canaan and
the General Partners may also explore other alternatives, such as the sale of
the Coral Group to a third party, but there is no assurance that Canaan and the
General Partners could find a third party interested in purchasing as such.  The
terms and conditions of any such purchase and sale agreement would be as
favorable as the terms offered pursuant to the combination transactions.

          As of December 31, 1999, the 1993 Partnership had bank indebtedness of
$494,800 which is equal to 9% of the Present Value of its oil and gas reserves.
If the combination transactions are not approved, the General Partners
anticipate that amortization of such bank debt will begin prior to year end 2000
and such amortization will have an adverse affect on limited partner cash
distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1993 Partnership is $76,500 of which a maximum of $68,850 would be allocated
to limited partners if all limited partners voted in favor of the combination
transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was continued.  This value is referred to as the
"Continuation Value" and is based on the following assumptions:

          .  The estimated future net revenues from the sale of oil and gas are
             based on the same prices and costs that are used to estimate the
             Reserve Value for purposes of the Exchange Value.

          .  The partnerships will continue to incur general administrative
             expenses in favor of the General Partners as provided in the
             applicable partnership agreement in the amount of 5% of the amount
             of distributable cash.

          .  Any partnership with bank debt is assumed to amortize such debt on
             a 36 month level amortization basis, assuming an interest rate of
             9%, beginning July 31, 2000.

                                      -8-
<PAGE>

          .   The estimated future net cash flows have been discounted at a
              discount rate of 10% to arrive at the estimated Continuation
              Value.

          Table E in this Supplement provides a comparison of Exchange Value,
Appraised Value and Continuation Value for the 1993-I Partnership

                    Calculation of Estimated Exchange Value

          The Exchange Value is estimated based on Canaan's estimate of cash
distributions and interest expense from the September 30, 1999 Effective Date to
an assumed closing date of July 31, 2000. Variances in actual cash distributions
and interest expense or a change in the closing date will result in a change in
the Exchange Value for the partnership and will similarly change Exchange Values
for other Combining Entities.

    represents a return of a limited partner's original investment. Until a

    capital.

General

          This Supplement relates to the proposed "combination transactions"
involving Canaan Energy Corporation. In the proposed combination transactions:

          .    Canaan will acquire all of the limited partners' and Additional
               General Partners' interests in the eight oil and gas limited
               partnerships previously sponsored by Coral Reserves, Inc. and
               Coral Reserves Energy Corp., affiliates of Canaan and the General
               Partners of the partnerships;

          .    Canaan will acquire 100% of the stock of the General Partners of
               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities". When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers. A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash. The owners of each of the
Combining Entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of
<PAGE>

such entity relative to the total Exchange Value of all Combining Entities. The
Exchange Value was determined by Canaan and is based on a valuation of each
Combining Entity's oil and gas Reserve Values and other assets and liabilities.
The Reserves Values were determined by Netherland, Sewell & Associates, Inc. an
independent petroleum engineering and consulting firm, using the same price,
cost, effective date and discount rate assumptions for each entity. A limited
partner in any partnership may also elect to receive cash in lieu of Canaan
common stock equal to the "Appraised Value" of his interest in the partnership.

          The Prospectus/Proxy Statement dated ____________, 2000, which we
refer to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions. This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1993
Partnership. The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.


                                 RISK FACTORS

          There are numerous risks associated with the combination transactions.
For a more complete description of these risk factors, please see:

               the Prospectus.


Risks Related to the 1993 Partnership

          There are no risk factors applicable to the 1993 Partnership that are
materially different from the risk factors described in the Prospectus.

                               TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .    No gain or loss will be recognized by a limited partner as a
               result of the receipt of Canaan common stock in connection with
               the combination transactions.

          .    The basis of the Canaan common stock received by each limited
               partner will be equal to the basis of his partnership interest
               exchanged for such stock.

          .    The holding period for the Canaan common stock for purposes of
               computing eligibility for long-term capital gain or loss will
               include the period of a limited partner's ownership of his
               partnership interest exchanged for such stock and, to the extent
               the Canaan common stock received is attributable to certain
               ordinary income assets of the partnership, may begin on the day
               after the closing of the combination transactions.

          .    A limited partner who receives cash will recognize gain or loss
               equal to the difference between the cash received and his
               adjusted tax basis of his limited partnership interest on the
               date of the closing of the combination transactions. Gain
               recognized by a limited partner will be capital except to the
               extent of such limited partner's share of ordinary income assets,
               including recapture of depletion, depreciation and intangible
               drilling cost deductions previously allocated to a limited
               partner.

    METHOD OF DETERMINING COMBINATION EXCHANGE VALUES AND APPRAISED VALUES

          The following is a summary of the methods of determining the Exchange
Values and Appraised Values. For more detailed information concerning the
subject, please see the following sections of the Prospectus:

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities. The Exchange Value takes into consideration the value
of each Combining Entities oil and gas reserves determined as described below
and the other assets and liabilities of each Combining Entity as adjusted for
other items for Canaan, Indian and the 1996 and 1996-I partnerships. The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values. This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity. The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity. Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999. We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers. However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties. The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

                                      -4-
<PAGE>

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.

          .    For Canaan, an upward adjustment of $5.0 million for the value of
               its "operating rights" as described in the Prospectus.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for the Indian Contingent
               Production Payment as described in the Prospectus.


Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared. In each of the partnerships except 1993-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner. Accordingly, in each
of those partnerships in which payout has not already occurred as to all limited
partners as of the Effective Date, the Reserve Value was allocated first among
the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          As of March 31, 2000, "payout" had not occurred for any limited
partners in the 1993 Partnership.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues. In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date. This allocation will be made prior
to the allocation of the remaining Reserve Value and other remaining components
of Exchange Value to the limited partners and the General Partners.

                                      -5-
<PAGE>

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships. Accordingly, the Exchange Value allocated to the General Partner
in these partnerships will be reduced to take into consideration the amount of
the Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share. The Placing Brokers will receive cash equal to the 40% of their
Exchange Value and their share of Canaan common stock will be determined based
on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership. The Appraised Value was determined based
on an appraisal by Madison Energy Advisors of each partnership's oil and gas
properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values. The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership. The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership. The Appraised Value
for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount. Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

                                      -6-

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1993 Partnership and Table B for the calculation of the Appraised Value
of the 1993 Partnership.


           FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions. The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values. The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations. By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest. This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

          INFORMATION CONCERNING THE 1993 PARTNERSHIP

General
          The 1993 Partnership was formed in July, 1993 and raised $6.5
million of limited partner capital contributions. As of March 31, 2000, the 1993
Partnership had distributed $5.9 million in cash to limited partners
representing 91% of their original investment. The 1993 Partnership has not
achieved payout for any limited partners.

          The term of the 1993 Partnership is until December 31, 2012 unless the
partnership is earlier terminated in accordance with the applicable provisions
of the Partnership Agreement.

<PAGE>

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1993-I Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1993-I
Partnership will continue in its business as previously conducted.  However, it
is possible a new transaction might be provoked by Canaan or the General
Partners, but no other terms have been discussed or considered by them.  In
addition, Canaan and the General Partners may also explore other alternatives,
such as the sale of the Coral Group to a third party, but there is no assurance
that Canaan and the General Partners could find a third party interested in
purchasing as such.  The terms and conditions of any such purchase and sale
agreement would be as favorable as the terms offered pursuant to the combination
transactions.

          As of December 31, 1999, the 1993-I Partnership had bank indebtedness
of $375,500 which is equal to 18% of the Present Value of its oil and gas
reserves.  If the combination transactions are not approved, the General
Partners anticipate that amortization of such bank debt will begin prior to year
end 2000 and such amortization will have an adverse affect on limited partner
cash distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1993-I Partnership is $34,000 of which a maximum of $29,750 would be
allocated to limited partners if all limited partners voted in favor of the
combination transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was continued.  This value is referred to as the
"Continuation Value" and is based on the following assumptions:

          .  The estimated future net revenues from the sale of oil and gas are
             based on the same prices and costs that are used to estimate the
             Reserve Value for purposes of the Exchange Value.

          .  The partnerships will continue to incur general administrative
             expenses in favor of the General Partners as provided in the
             applicable partnership agreement in the amount of 5% of the amount
             of distributable cash.

          .  Any partnership with bank debt is assumed to amortize such debt on
             a 36 month level amortization basis, assuming an interest rate of
             9%, beginning July 31, 2000.

                                      -8-
<PAGE>

          .    The estimated future net cash flows have been discounted at a
               discount rate of 10% to arrive at the estimated Continuation
               Value.

Appraised Value and Continuation Value for the 1993 Partnership

                    Calculation of Estimated Exchange Value

          The Exchange Value is estimated based on Canaan's estimate of cash
distributions and interest expense from the September 30, 1999 Effective Date to
an assumed closing date of July 31, 2000. Variances in actual cash distributions
and interest expense or a change in the closing date will result in a change in
the Exchange Value for the partnership and will similarly change Exchange Values
for other Combining Entities.

         more than 10% of the Reserve Value or from which the partnership
         derived more than 10% of its cash flow or net income for the year ended
         December 31, 1999.

         and Canaan set forth in the table is approximately 96.3% of the sum of
         their respective components of Exchange Value because the operating

                   Calculation of Estimated Appraised Value

          The Appraised Value is estimated based on Canaan's estimate of
property net revenue from the September 30, 1999 Effective Date to an assumed
closing date of July 31, 2000. Variances in actual net revenue or a change in
the closing date will result in a change in the Appraised Value for the
partnership and will similarly change Appraised Values for other partnerships.
Property net revenues include proceeds from sale of production less production
taxes and operating expense.

(1)  Because of depletion (which is usually higher in the early years of
     production), a portion of every distribution of revenues from properties
     represents a return of a limited partner's original investment. Until a
     limited partner receives cash distributions equal to his original
     investment, 100% of such distributions may be deemed to be a return of
     capital.

          The Exchange Value does not represent the fair value of the
partnership or its net assets and is being used solely for purposes of
determining the relative ownership of Canaan by the 1993 Partnership. There is
no assurance that the value of common stock received by a limited partner will
be equal to Exchange Value. The Appraised Value is the amount a limited partner
may elect to receive in cash and is based on an appraisal of the partnership's
assets and an assumed liquidation of the 1993 Partnership.

                          PROSPECTUS/PROXY STATEMENT
                           Dated ____________, 2000


              The date of this Supplement is _______________, 2000

General

          This Supplement relates to the proposed "combination transactions"
involving Canaan Energy Corporation.  In the proposed combination transactions:

          .    Canaan will acquire all of the limited partners' and Additional
               General Partners' interests in the eight oil and gas limited
               partnerships previously sponsored by Coral Reserves, Inc. and
               Coral Reserves Energy Corp., affiliates of Canaan and the General
               Partners of the partnerships;

          .    Canaan will acquire 100% of the stock of the General Partners of
               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities".  When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers.  A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash.  The owners of each of the
Combining Entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of


<PAGE>

such entity relative to the total Exchange Value of all Combining Entities. The
Exchange Value was determined by Canaan and is based on a valuation of each
Combining Entity's oil and gas Reserve Values and other assets and liabilities.
The Reserves Values were determined by Netherland, Sewell & Associates, Inc. an
independent petroleum engineering and consulting firm, using the same price,
cost, effective date and discount rate assumptions for each entity. A limited
partner in any partnership may also elect to receive cash in lieu of Canaan
common stock equal to the "Appraised Value" of his interest in the partnership.

          The Prospectus/Proxy Statement dated _____________, 2000, which we
refer to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions.  This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1995
Partnership.  The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.


                                  RISK FACTORS

          There are numerous risks associated with the combination transactions.
For a more complete description of these risk factors, please see:

                                TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .    No gain or loss will be recognized by a limited partner as a
               result of the receipt of Canaan common stock in connection with
               the combination transactions.

          .    The basis of the Canaan common stock received by each limited
               partner will be equal to the basis of his partnership interest
               exchanged for such stock.

          .    The holding period for the Canaan common stock for purposes of
               computing eligibility for long-term capital gain or loss will
               include the period of a limited partner's ownership of his
               partnership interest exchanged for such stock and, to the extent
               the Canaan common stock received is attributable to certain
               ordinary income assets of the partnership, may begin on the day
               after the closing of the combination transactions.

          .    A limited partner who receives cash will recognize gain or loss
               equal to the difference between the cash received and his
               adjusted tax basis of his limited partnership interest on the
               date of the closing of the combination transactions. Gain
               recognized by a limited partner will be capital except to the
               extent of such limited partner's share of ordinary income assets,
               including recapture of depletion, depreciation and intangible
               drilling cost deductions previously allocated to a limited
               partner.

               of the Prospectus.

     METHOD OF DETERMINING COMBINATION EXCHANGE VALUES AND APPRAISED VALUES

          The following is a summary of the methods of determining the Exchange
Values and Appraised Values.  For more detailed information concerning the
subject, please see the following sections of the Prospectus:

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities.  The Exchange Value takes into consideration the
value of each Combining Entities oil and gas reserves determined as described
below and the other assets and liabilities of each Combining Entity as adjusted
for other items for Canaan, Indian and the 1996 and 1996-I partnerships.  The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values.  This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity.  The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity.  Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999.  We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers.  However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties.  The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

                                      -4-
<PAGE>

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.

          .    For Canaan, an upward adjustment of $5.0 million for the value of
               its "operating rights" as described in the Prospectus.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for the Indian Contingent
               Production Payment as described in the Prospectus.


Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared.  In each of the partnerships except 1993-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner.  Accordingly, in
each of those partnerships in which payout has not already occurred as to all
limited partners as of the Effective Date, the Reserve Value was allocated first
among the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          As of March 31, 2000, "payout" had not occurred for any limited
partners in the 1995 Partnership.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues.  In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date.  This allocation will be made prior
to the allocation of the remaining Reserve Value and other components of
Exchange Value to the limited partners and the General Partners.

                                      -5-
<PAGE>

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships.  Accordingly, the Exchange Value allocated to the General Partner
in these partnerships will be reduced to take into consideration the amount of
the Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share.  The Placing Brokers will receive cash equal to the 40% of
their Exchange Value and their share of Canaan common stock will be determined
based on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership.  The Appraised Value was determined
based on an appraisal by Madison Energy Advisors of each partnership's oil and
gas properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values.  The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes  the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership.  The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership.  The Appraised
Value for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount.  Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1995 Partnership and Table B for the calculation of the Appraised Value
of the 1995 Partnership.


            FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions.  The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values.  The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations.  By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest.  This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

          INFORMATION CONCERNING THE 1995 PARTNERSHIP

General
          The 1995 Partnership was formed in April, 1995 and raised $6.8 million
of limited partner capital contributions.  As of March 31, 2000, the 1995
Partnership had distributed $5.2 million in cash to limited partners
representing 76% of their original investment.  The 1995 Partnership has not
achieved payout for any limited partners.

          The term of the 1995 Partnership is until December 31, 2014 unless the
partnership is earlier terminated in accordance with the applicable provisions
of the Partnership Agreement.

                                      -7-
<PAGE>

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1995 Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1995 Partnership
will continue in its business as previously conducted.  However, it is possible
a new transaction might be provoked by Canaan or the General Partners, but no
other terms have been discussed or considered by them.  In addition, Canaan and
the General Partners may also explore other alternatives, such as the sale of
the Coral Group to a third party, but there is no assurance that Canaan and the
General Partners could find a third party interested in purchasing as such.  The
terms and conditions of any such purchase and sale agreement would be as
favorable as the terms offered pursuant to the combination transactions.

          The 1995 Partnership does not have any material bank indebtedness.  If
the combination transactions are not approved, the General Partners anticipate
that the 1995 Partnership may incur indebtedness to provide funds to finance
additional development costs.  If so amortization of any bank debt will have an
adverse affect on limited partner cash distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1995 Partnership is $127,500 of which a maximum of $114,750 would be
allocated to limited partners if all limited partners voted in favor of the
combination transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was continued.  This value is referred to as the
"Continuation Value" and is based on the following assumptions:

          .    The estimated future net revenues from the sale of oil and gas
               are based on the same prices and costs that are used to estimate
               the Reserve Value for purposes of the Exchange Value.

          .    The partnerships will continue to incur general administrative
               expenses in favor of the General Partners as provided in the
               applicable partnership agreement in the amount of 5% of the
               amount of distributable cash.

          .    Any partnership with bank debt is assumed to amortize such debt
               on a 36 month level amortization basis, assuming an interest rate
               of 9%, beginning July 31, 2000.

                                      -8-
<PAGE>

          .    The estimated future net cash flows have been discounted at a
               discount rate of 10% to arrive at the estimated Continuation
               Value.

          Table E in this Supplement provides a comparison of Exchange Value,
Appraised Value and Continuation Value for the 1995 Partnership

                    Calculation of Estimated Exchange Value

          The Exchange Value is estimated based on Canaan's estimate of cash
distributions and interest expense from the September 30, 1999 Effective Date to
an assumed closing date of July 31, 2000.  Variances in actual cash
distributions and interest expense or a change in the closing date will result
in a change in the Exchange Value for the partnership and will similarly change
Exchange Values for other Combining Entities.

                    Calculation of Estimated Appraised Value

          The Appraised Value is estimated based on Canaan's estimate of
property net revenue from the September 30, 1999 Effective Date to an assumed
closing date of July 31, 2000. Variances in actual net revenue or a change in
the closing date will result in a change in the Appraised Value for the
partnership and will similarly change Appraised Values for other partnerships.
Property net revenues include proceeds from sale of production less production
taxes and operating expense.

(1) Because of depletion (which is usually higher in the early years of
    production), a portion of every distribution of revenues from properties
    represents a return of a limited partner's original investment.  Until a
    limited partner receives cash distributions equal to his original
    investment, 100% of such distributions may be deemed to be a return of
    capital.

be equal to Exchange Value.  The Appraised Value is the amount a limited partner
may elect to receive in cash and is based on an appraisal of the partnership's

General

          This Supplement relates to the proposed "combination transactions"
involving Canaan Energy Corporation.  In the proposed combination transactions:

          .    Canaan will acquire all of the limited partners' and Additional
               General Partners' interests in the eight oil and gas limited
               partnerships previously sponsored by Coral Reserves, Inc. and
               Coral Reserves Energy Corp., affiliates of Canaan and the General
               Partners of the partnerships;

          .    Canaan will acquire 100% of the stock of the General Partners of
               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities".  When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers.  A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash.  The owners of each of the
Combining Entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of
<PAGE>

such entity relative to the total Exchange Value of all Combining Entities. The
Exchange Value was determined by Canaan and is based on a valuation of each
Combining Entity's oil and gas Reserve Values and other assets and liabilities.
The Reserves Values were determined by Netherland, Sewell & Associates, Inc. an
independent petroleum engineering and consulting firm, using the same price,
cost, effective date and discount rate assumptions for each entity. A limited
partner in any partnership may also elect to receive cash in lieu of Canaan
common stock equal to the "Appraised Value" of his interest in the partnership.

          The Prospectus/Proxy Statement dated ___________, 2000, which we refer
to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions.  This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1996-I
Partnership.  The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.

                                 RISK FACTORS

          There are numerous risks associated with the combination transactions.
For a more complete description of these risk factors, please see:

          .    "Risk Factors and Material Considerations" beginning on page 30
     of the Prospectus.

          .    "Comparison of Securityholder Rights" beginning on page 156 of
               the Prospectus.

Risks Related to the 1996-I Partnership

          For the 1996-I Partnership, failure to approve the combination
transactions may result in a material adverse affect on the current limited
partners due to a $3,000,000 downward adjustment in the Indian Contingent
Production Payment negotiated in connection with the Indian Acquisition
Agreement.

                               TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .    No gain or loss will be recognized by a limited partner as a
               result of the receipt of Canaan common stock in connection with
               the combination transactions.

          .    The basis of the Canaan common stock received by each limited
               partner will be equal to the basis of his partnership interest
               exchanged for such stock.

          .    The holding period for the Canaan common stock for purposes of
               computing eligibility for long-term capital gain or loss will
               include the period of a limited partner's ownership of his
               partnership interest exchanged for such stock and, to the extent
               the Canaan common stock received is attributable to certain
               ordinary income assets of the partnership, may begin on the day
               after the closing of the combination transactions.

          .    A limited partner who receives cash will recognize gain or loss
               equal to the difference between the cash received and his
               adjusted tax basis of his limited partnership interest on the
               date of the closing of the combination transactions. Gain
               recognized by a limited partner will be capital except to the
               extent of such limited partner's share of ordinary income assets,
               including recapture of depletion, depreciation and intangible
               drilling cost deductions previously allocated to a limited
               partner.

          For additional information please see:

          .    "Material Federal Income Tax Consequences" beginning on page 90
     of the Prospectus.

    METHOD OF DETERMINING COMBINATION EXCHANGE VALUES AND APPRAISED VALUES

          The following is a summary of the methods of determining the Exchange
Values and Appraised Values.  For more detailed information concerning the
subject, please see the following sections of the Prospectus:

          .    "Summary - Method of Determining Combination Exchange Values" on
               page 8.

               Values" on page 62.

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities.  The Exchange Value takes into consideration the
value of each Combining Entities oil and gas reserves determined as described
below and the other assets and liabilities of each Combining Entity as adjusted
for other items for Canaan, Indian and the 1996 and 1996-I partnerships.  The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values.  This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity.  The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity.  Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999.  We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers.  However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties.  The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

                                      -4-
<PAGE>

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.

          .    For Canaan, an upward adjustment of $5.0 million for the value of

Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared.  In each of the partnerships except 1996-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner.  Accordingly, in
each of those partnerships in which payout has not already occurred as to all
limited partners as of the Effective Date, the Reserve Value was allocated first
among the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          In the partnerships other than 1990, 1991, 1996-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues.  In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date.  This allocation will be made prior
to the allocation of the remaining Reserve Value and other components of
Exchange Value to the limited partners and the General Partners.

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships.  Accordingly, the Exchange Value allocated to the General Partner
in these

                                      -5-
<PAGE>

partnerships will be reduced to take into consideration the amount of the
Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share. The Placing Brokers will receive cash equal to the 40% of their
Exchange Value and their share of Canaan common stock will be determined based
on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership.  The Appraised Value was determined
based on an appraisal by Madison Energy Advisors of each partnership's oil and
gas properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values.  The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes  the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership.  The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership.  The Appraised
Value for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount.  Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1996-I Partnership and Table B for the calculation of the Appraised Value
of the 1996-I Partnership.


                   FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions.  The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values.  The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations.  By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest.  This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

                 INFORMATION CONCERNING THE 1996-I PARTNERSHIP

General
          The 1996-I Partnership was formed in December, 1995 and raised $6.5
million of limited partner capital contributions.  As of March 31, 2000, the
1996-I Partnership had distributed $3.0 million in cash to limited partners
representing 47% of their original investment.

          The term of the 1996-I Partnership is until December 31, 2014 unless
the partnership is earlier terminated in accordance with the applicable
provisions of the Partnership Agreement.

                                      -7-
<PAGE>

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1996 Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1996 Partnership
will continue in its business as previously conducted.  However, it is possible
a new transaction might be provoked by Canaan or the General Partners, but no
other terms have been discussed or considered by them.  In addition, Canaan and
the General Partners may also explore other alternatives, such as the sale of
the Coral Group to a third party, but there is no assurance that Canaan and the
General Partners could find a third party interested in purchasing as such.  The
terms and conditions of any such purchase and sale agreement would be as
favorable as the terms offered pursuant to the combination transactions.

          If the combination transactions are not consummated, the amount of the
remaining balance of the Contingent Production Payment owing from Indian to the
1996 and 1996-I partnerships will be reduced by $3 million.  This will result in
no gain or return on the amount of these partnerships' investments in the
Contingent Production Payment.  The payment of this obligation is subordinate to
Indian's obligations to its bank lenders and depending on the amount of the
liquidation proceeds, the Contingent Production Payment may not be paid in full.
The Coral Group, including these partnerships, would also be entitled to share a
portion of the 50% of the remaining proceeds of liquidation otherwise
distributable to Indian shareholders, which is uncertain.  The amount invested
in the Contingent Production Payment represented 33% of the initial capital of
the 1996 partnership and 43% of the initial capital of the 1996-I partnership.
Thus, the failure to approve the combination transactions would adversely affect
the returns to the limited partners in these partnerships unless the Contingent
Production Payment repayment proceeds are successfully reinvested.

          As of December 31, 1999, the 1996 Partnership had bank indebtedness of
$2,272,000 which is equal to 31% of the Present Value of its oil and gas
reserves.  If the combination transactions are not approved, the General
Partners anticipate that amortization of such bank debt will begin prior to year
end 2000 and such amortization will have an adverse affect on limited partner
cash distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1996 Partnership is $187,000 of which a maximum of $168,300 would be
allocated to limited partners if all limited partners voted in favor of the
combination transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was

                                      -8-
<PAGE>

continued. This value is referred to as the "Continuation Value" and is based on
the following assumptions:

          .    The estimated future net revenues from the sale of oil and gas
               are based on the same prices and costs that are used to estimate
               the Reserve Value for purposes of the Exchange Value.

          .    The partnerships will continue to incur general administrative
               expenses in favor of the General Partners as provided in the
               applicable partnership agreement in the amount of 5% of the
               amount of distributable cash.

          .    Any partnership with bank debt is assumed to amortize such debt
               on a 36 month level amortization basis, assuming an interest rate
               of 9%, beginning July 31, 2000.

          .    The estimated future net cash flows have been discounted at a
               discount rate of 10% to arrive at the estimated Continuation
               Value.

Appraised Value and Continuation Value for the 1996-I Partnership

an assumed closing date of July 31, 2000.  Variances in actual cash
distributions and interest expense or a change in the closing date will result
in a change in the Exchange Value for the partnership and will similarly change
Exchange Values for other Combining Entities.

(1) Because of depletion (which is usually higher in the early years of
    production), a portion of every distribution of revenues from properties
    represents a return of a limited partner's original investment.  Until a
    limited partner receives cash distributions equal to his original
    investment, 100% of such distributions may be deemed to be a return of
    capital.

is no assurance that the value of common stock received by a limited partner
will be equal to Exchange Value.  The Appraised Value is the amount a limited

             The date of this Supplement is _______________, 2000

General

          This Supplement relates to the proposed "combination transactions"
involving Canaan Energy Corporation.  In the proposed combination transactions:

          .    Canaan will acquire all of the limited partners' and Additional
               General Partners' interests in the eight oil and gas limited
               partnerships previously sponsored by Coral Reserves, Inc. and
               Coral Reserves Energy Corp., affiliates of Canaan and the General
               Partners of the partnerships;

          .    Canaan will acquire 100% of the stock of the General Partners of
               the partnerships;

          .    Canaan will acquire 100% of the stock of Indian Oil Company, an
               unaffiliated oil and gas company;

          .    Canaan will acquire 100% of the stock of Canaan Securities, Inc.,
               an unaffiliated broker/dealer which has previously participated
               in the marketing of the limited partnership interests and
               provides ongoing reporting services to limited partners; and

          .    Existing owners of Canaan's common stock will receive additional
               shares of common stock based on Canaan's relative share of the
               total "Exchange Value" as described below.

          We refer to Canaan, the partnerships, the General Partners, Indian Oil
Company and Canaan Securities as the "Combining Entities".  When we refer to the
Coral Group we mean Canaan, the partnerships, the General Partnerships, the
Additional General Partners, Canaan Securities and the Placing Brokers.  A total
of 5,000,000 shares of Canaan common stock will be issued and be outstanding
after the combination transactions, less the number of shares otherwise issuable
to limited partners who elect to receive cash.  The owners of each of the
Combining Entities will receive shares of Canaan common stock in proportion to
the "Exchange Value" of
<PAGE>

such entity relative to the total Exchange Value of all Combining Entities. The
Exchange Value was determined by Canaan and is based on a valuation of each
Combining Entity's oil and gas Reserve Values and other assets and liabilities.
The Reserves Values were determined by Netherland, Sewell & Associates, Inc. an
independent petroleum engineering and consulting firm, using the same price,
cost, effective date and discount rate assumptions for each entity. A limited
partner in any partnership may also elect to receive cash in lieu of Canaan
common stock equal to the "Appraised Value" of his interest in the partnership.

          The Prospectus/Proxy Statement dated ____________, 2000, which we
refer to as the "Prospectus" describes the combination transactions in detail.
However, the effects of the combination transactions may be different for
limited partners in the various partnerships. Accordingly, a supplement has been
prepared for each of the eight partnerships eligible to participate in the
combination transactions. This Supplement provides information regarding the
effects of the combination transactions on the limited partners of the 1996
Partnership. The General Partner will promptly mail a copy of any supplement
relating to other partnerships, without charge, upon request by any limited
partner or his representative who has been so designated in writing, addressed
to: Canaan Energy Corporation, 119 N. Robinson, Suite 600, Oklahoma City,
Oklahoma 73102.

          Before voting on the plan of combination, limited partners should
carefully consider the following factors in addition to the other information
included in the Prospectus.

                                 RISK FACTORS

          There are numerous risks associated with the combination transactions.
For a more complete description of these risk factors, please see:

          .    "Risk Factors and Material Considerations" beginning on page 30
               of the Prospectus.

          .    "Comparison of Securityholder Rights" beginning on page 156 of
               the Prospectus.

 Risks Related to the 1996 Partnership

          For the 1996 Partnership, failure to approve the combination
transactions may result in a material adverse affect on the current limited
partners due to a $3,000,000 downward adjustment in the Indian Contingent
Production Payment negotiated in connection with the Indian Acquisition
Agreement.

                               TAX CONSEQUENCES

          Crowe & Dunlevy, counsel to Canaan, has rendered an opinion that:

          .    No gain or loss will be recognized by a limited partner as a
               result of the receipt of Canaan common stock in connection with
               the combination transactions.

          .    The basis of the Canaan common stock received by each limited
               partner will be equal to the basis of his partnership interest
               exchanged for such stock.

          .    The holding period for the Canaan common stock for purposes of
               computing eligibility for long-term capital gain or loss will
               include the period of a limited partner's ownership of his
               partnership interest exchanged for such stock and, to the extent
               the Canaan common stock received is attributable to certain
               ordinary income assets of the partnership, may begin on the day
               after the closing of the combination transactions.

          .    A limited partner who receives cash will recognize gain or loss
               equal to the difference between the cash received and his
               adjusted tax basis of his limited partnership interest on the
               date of the closing of the combination transactions. Gain
               recognized by a limited partner will be capital except to the
               extent of such limited partner's share of ordinary income assets,
               including recapture of depletion, depreciation and intangible
               drilling cost deductions previously allocated to a limited
               partner.

    METHOD OF DETERMINING COMBINATION EXCHANGE VALUES AND APPRAISED VALUES

          The following is a summary of the methods of determining the Exchange
Values and Appraised Values.  For more detailed information concerning the
subject, please see the following sections of the Prospectus:

               page 8.

               Values" on page 62.

General

          Canaan and the General Partners determined the Exchange Value for each
of the Combining Entities.  The Exchange Value takes into consideration the
value of each Combining Entities oil and gas reserves determined as described
below and the other assets and liabilities of each Combining Entity as adjusted
for other items for Canaan, Indian and the 1996 and 1996-I partnerships.  The
Exchange Value is used to allocate the shares of Canaan common stock to each
Combining Entity based on relative Exchange Values.  This methodology is used
based on the arm's length negotiated agreement between Indian and Canaan and the
General Partners in connection with the negotiation of the Indian Acquisition
Agreement and because it is a consistent methodology for establishing the
relative value of each Combining Entity.  The Exchange Value may not represent
fair market value.

          Canaan engaged Netherland, Sewell & Associates, Inc. to estimate a
value of the oil and gas reserves for each Combining Entity.  Netherland Sewell
estimated the reserves, future net revenues therefrom and the present value of
such future net revenues for each Combining Entity as of September 30, 1999.  We
refer to the evaluation date of September 30, 1999 as the "Effective Date" and
the present value of the estimated future net revenues from estimated reserves
as of the Effective Date as the "Reserve Value" for each Combining Entity.

          We refer to the reserves estimated by Netherland Sewell as "Exchange
Reserves". They include estimates of proved undeveloped reserves as well as
proved developed reserves, both producing and nonproducing, as the term "proved"
is defined by the Society of Petroleum Engineers.  However, because the reserves
are estimated using prices different from those required by the Securities and
Exchange Commission, we use the term "Exchange" instead of "proved" to describe
the reserve estimates for the Exchange Value.

          The Reserve Value is an estimate only and does not represent the fair
market value of the underlying properties.  The Reserve Values are being used
solely for purposes of determining the relative value of each of the Combining
Entities in the combination transactions.

          The "Exchange Value" for each Combining Entity will be equal to:

          .    Reserve Value as of the Effective Date.

          .    Less bank debt at the closing date.

                                      -4-
<PAGE>

          .    Minus interest paid or accrued on bank or other debt assumed by
               Canaan from the Effective Date to the closing date.

          .    For limited partners, Additional General Partners, Canaan
               Securities and Placing Brokers, minus their share of cash
               distributions from production subsequent to the Effective Date
               and before the closing date.

          .    An adjustment for any gas imbalances which are not expected to be
               material.

          .    For Canaan, an upward adjustment of $5.0 million for the value of
               its "operating rights" as described in the Prospectus.

          .    For the 1996 and 1996-I Partnerships, upward adjustments, and for
               Indian, a downward adjustment, for the Indian Contingent
               Production Payment as described in the Prospectus.

Partnership Exchange Values and Allocation to Partners, Canaan Securities and
Placing Brokers

          The Exchange Value for each of the partnerships will first be
determined as described above.

          As between the limited partners and the General Partner and the
Additional General Partners in each partnership, the Exchange Value will
generally be allocated among them in the ratio in which net revenues and cash
distributions are shared.  In each of the partnerships except 1993-I and 1996-I,
the General Partners' share of the net revenues and cash distributions increases
when "payout" occurs as to each individual limited partner.  Accordingly, in
each of those partnerships in which payout has not already occurred as to all
limited partners as of the Effective Date, the Reserve Value was allocated first
among the partners in their respective before payout sharing ratios until payout
occurred and any remaining Reserve Value and other components of Exchange Value
was allocated in after payout sharing ratios.

          As of March 31, 2000, "payout" had not occurred for any limited
partners in the 1996 Partnership.

          In the partnerships other than 1990, 1991, 1993-I and 1996-I, Canaan
Securities receives a fee for providing reporting services to the partnership
which is equal to 1.5% of partnership gross revenues.  In each of these
partnerships, a portion of the Reserve Value (calculated based on gross
revenues) will be allocated to Canaan Securities representing its rights to
receive such fee adjusted for any payments for such fee subsequent to the
Effective Date and before the closing date.  This allocation will be made prior
to the allocation of the remaining Reserve Value and other components of
Exchange Value to the limited partners and the General Partners.

                                      -5-
<PAGE>

          The marketing arrangements entered into in connection with the sale of
interests in partnerships provided for certain fees to be paid to Canaan
Securities and Placing Brokers. Such fees are payable out of the cash
distributions otherwise distributable to the General Partner in such
partnerships.  Accordingly, the Exchange Value allocated to the General Partner
in these partnerships will be reduced to take into consideration the amount of
the Exchange Value allocable to the rights of Canaan Securities and the Placing
Brokers to receive future distributions of net cash flow out of the General
Partner's share.  The Placing Brokers will receive cash equal to the 40% of
their Exchange Value and their share of Canaan common stock will be determined
based on the balance of their Exchange Value.

          As discussed above, for the limited partners, the Additional General
Partners, Canaan Securities and the Placing Brokers, an adjustment to their
Exchange Values will be made for cash distributions from production subsequent
to the Effective Date and before the closing date.

          If the allocation of Exchange Value within a partnership plus
historical cash distributions is not at least 115% of the capital contributions
of the limited partners as a group, the Exchange Value shall be first allocated
to limited partners until this amount is achieved and the balance of the
Exchange Value will be allocated based on revenue sharing percentages. Canaan
and the General Partners believe that the 1996 partnership will be the only
partnership in which this priority allocation of Exchange Value will be
necessary.

Method of Determining Appraised Value

          A limited partner may elect to receive cash equal to the Appraised
Value of his interest in a partnership.  The Appraised Value was determined
based on an appraisal by Madison Energy Advisors of each partnership's oil and
gas properties valuing them as if sold in an orderly manner and in a reasonable
period of time and in a manner consistent with appropriate industry practice.
Other assets and liabilities of each partnership, consisting primarily of bank
debt and working capital were valued at their respective book values.  The
Appraised Value also takes into consideration the cost associated with the sale
of the partnership oil and gas properties and assumes  the proceeds of sale of
the partnership properties and working capital after payment of liabilities are
distributed in a liquidation of the partnership.  The appraisal was obtained in
order to satisfy the requirements of the National Association of Securities
Dealers that limited partners be offered the opportunity to receive cash equal
to the Appraised Value of their interest in the partnership.  The Appraised
Value for each partnership ranges from 56% to 93% of the Exchange Values.

          If the Appraised Value of a limited partner's interest plus historical
cash distributions is less than 110% of the amount of the limited partner's
original investment, the Appraised Value for a limited partner electing cash
will be increased to such amount.  Canaan and the General Partners believe that
the limited partners of the 1996 and 1996-I partnerships will be the only
limited partners whose Appraised Value will be affected by this adjustment.

Calculation of Exchange Value and Appraised Value

          See Table A in this Supplement for calculation of the Exchange Value
of the 1996 Partnership and Table B for the calculation of the Appraised Value
of the 1996 Partnership.


                   FAIRNESS OF THE COMBINATION TRANSACTIONS

          Canaan and the General Partners believe that the proposed combination
transactions are fair to the limited partners of each of the partnerships
receiving Canaan common stock or cash at Appraised Value and are fair to the
partnerships as a whole.

          Please see "Recommendation of the General Partners and Fairness of the
Combination Transactions" on page 74 of the Prospectus for a detailed discussion
of the reasons for the General Partners' opinions.  The following summarizes the
principal reasons for the General Partners' opinions.

          The principal structural element affecting the limited partners and
the other parties to the combination transactions is the determination of the
Exchange Values.  The Exchange Values are based primarily on the Reserve Value
based on Netherland Sewell's independent valuations.  By using Reserve Values
calculated in a consistent manner by a single engineer based on the same price,
cost and discount assumptions, Canaan and the General Partners believe that the
relative value of each of the Combining Entities has been fairly determined for
purposes of determining its relative ownership of Canaan after the combination
transactions.

          A limited partner of a partnership may elect to receive cash in lieu
of Canaan common stock in an amount equal to the Appraised Value of such limited
partner's interest.  This cash election provides the opportunity for limited
partners who are unwilling to take market risks with respect to Canaan common
stock the opportunity to receive cash in an amount which Canaan and the General
Partners believe approximates fair value of their interest based on an appraisal
of the partnership oil and gas properties performed by an independent appraiser.

                  INFORMATION CONCERNING THE 1996 PARTNERSHIP

General
          The 1996 Partnership was formed in May, 1996 and raised $9.6 million
of limited partner capital contributions.  As of March 31, 2000, the 1996
Partnership had distributed $3.1 million in cash to limited partners
representing 32% of their original investment.  The 1996 Partnership has not
achieved payout for any limited partner.

          The term of the 1996 Partnership is until December 31, 2015 unless the
partnership is earlier terminated in accordance with the applicable provisions
of the Partnership Agreement.

                                      -7-
<PAGE>

          See "Information Concerning Partnerships" beginning on page 110 of the
Prospectus for additional information about the 1996-I Partnership.

Failure to Approve the Combination Transactions

          If the combination transactions are not approved, the 1996-I
Partnership will continue in its business as previously conducted.  However, it
is possible a new transaction might be provoked by Canaan or the General
Partners, but no other terms have been discussed or considered by them.  In
addition, Canaan and the General Partners may also explore other alternatives,
such as the sale of the Coral Group to a third party, but there is no assurance
that Canaan and the General Partners could find a third party interested in
purchasing as such.  The terms and conditions of any such purchase and sale
agreement would be as favorable as the terms offered pursuant to the combination
transactions.

          If the combination transactions are not consummated, the amount of the
remaining balance of the Contingent Production Payment owing from Indian to the
1996 and 1996-I partnerships will be reduced by $3 million.  This will result in
no gain or return on the amount of these partnerships' investments in the
Contingent Production Payment.  The payment of this obligation is subordinate to
Indian's obligations to its bank lenders and depending on the amount of the
liquidation proceeds, the Contingent Production Payment may not be paid in full.
The Coral Group, including these partnerships, would also be entitled to share a
portion of the 50% of the remaining proceeds of liquidation otherwise
distributable to Indian shareholders, which is uncertain.  The amount invested
in the Contingent Production Payment represented 33% of the initial capital of
the 1996 partnership and 43% of the initial capital of the 1996-I partnership.
Thus, the failure to approve the combination transactions would adversely affect
the returns to the limited partners in these partnerships unless the Contingent
Production Payment repayment proceeds are successfully reinvested.

          As of December 31, 1999, the 1996-I Partnership had bank indebtedness
of $1,948,000 which is equal to 33% of the Present Value of its oil and gas
reserves.  If the combination transactions are not approved, the General
Partners anticipate that amortization of such bank debt will begin prior to year
end 2000 and such amortization will have an adverse affect on limited partner
cash distributions.

          If the combination transactions are not consummated, costs and
expenses incurred in connection with the combination transaction proposals will
be borne by the Combining Entities, including the partnerships.  Limited
partners in each partnership will bear a portion of the costs allocated to each
partnership based on the percentage interest of limited partners voting in favor
of the combination transactions.  The estimated share of expenses allocated to
the 1996-I Partnership is $153,000 of which a maximum of $133,875 would be
allocated to limited partners if all limited partners voted in favor of the
combination transactions.

          Canaan and the General Partners have prepared an analysis of the
present value of the estimated future net cash flows to the limited partners
assuming that each partnership was

                                      -8-
<PAGE>

continued. This value is referred to as the "Continuation Value" and is based on
the following assumptions:

          .    The estimated future net revenues from the sale of oil and gas
               are based on the same prices and costs that are used to estimate
               the Reserve Value for purposes of the Exchange Value.

          .    The partnerships will continue to incur general administrative
               expenses in favor of the General Partners as provided in the
               applicable partnership agreement in the amount of 5% of the
               amount of distributable cash.

          .    Any partnership with bank debt is assumed to amortize such debt
               on a 36 month level amortization basis, assuming an interest rate
               of 9%, beginning July 31, 2000.

          .    The estimated future net cash flows have been discounted at a
               discount rate of 10% to arrive at the estimated Continuation
               Value.

                    Calculation of Estimated Exchange Value

          The Exchange Value is estimated based on Canaan's estimate of cash
distributions and interest expense from the September 30, 1999 Effective Date to
an assumed closing date of July 31, 2000.  Variances in actual cash
distributions and interest expense or a change in the closing date will result
in a change in the Exchange Value for the partnership and will similarly change
Exchange Values for other Combining Entities.

(1)  As determined by Netherland, Sewell & Associates, Inc.  See "Method of
     Determining Combination Exchange Values and Appraised Values" in the
     Prospectus.  No partnerships own an individual property representing more
     than 10% of the Reserve Value or from which the partnership derived more
     than 10% of its cash flow or net income for the year ended December 31,
     1999.

(2)  Assumes no limited partners elect to receive cash.  Placing Brokers' shares
     based on 60% of Exchange Value.

(3)  Assumes closing on July 31, 2000, and uses Netherland, Sewell reserve
     report to estimate property revenues and expenses and estimated interest
     rate on bank debt for purposes of calculating interest expense.

(4)  Adjustment for Indian Contingent Production Payment.  Balance before
     adjustment included in Working Capital as of Effective Date.

(5)  The "Estimated Exchange Value at Closing" for all of the partnerships and
     Canaan set forth in the table is approximately 96.3% of the sum of their
     respective components of Exchange Value because the operating rights
     adjustment to Canaan's Exchange Value within the Coral Group is excluded
     for purposes of computing the relative Exchange Value between the Coral
     Group and Indian.  See "Method of Determining Combination Exchange Values
     and Appraised Values" in the Prospectus for a more detailed explanation.

(6)  Estimated Exchange Value for limited partners adjusted to increase Exchange
     Value so limited partners receive Exchange Value plus cash distributions
     equal to 115% of original investment and other participants reduced
     accordingly.

                   Calculation of Estimated Appraised Value

          The Appraised Value is estimated based on Canaan's estimate of
property net revenue from the September 30, 1999 Effective Date to an assumed
closing date of July 31, 2000. Variances in actual net revenue or a change in
the closing date will result in a change in the Appraised Value for the
partnership and will similarly change Appraised Values for other partnerships.
Property net revenues include proceeds from sale of production less production
taxes and operating expense.

(1) Because of depletion (which is usually higher in the early years of
    production), a portion of every distribution of revenues from properties
    represents a return of a limited partner's original investment.  Until a
    limited partner receives cash distributions equal to his original
    investment, 100% of such distributions may be deemed to be a return of
    capital.

          The Exchange Value does not represent the fair value of the
partnership or its net assets and is being used solely for purposes of
determining the relative ownership of Canaan by the 1996 Partnership.  There is
no assurance that the value of common stock received by a limited partner will
be equal to Exchange Value.  The Appraised Value is the amount a limited partner
may elect to receive in cash and is based on an appraisal of the partnership's
assets and an assumed liquidation of the 1996 Partnership.

                    INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers.

     The Registrant's Certificate of Incorporation provides that, pursuant to
Oklahoma law, its directors shall not be liable for monetary damages for breach
of the directors' fiduciary duty of care to the Registrant and its stockholders.
The provision in the Certificate of Incorporation does not eliminate the duty of
care and, in appropriate circumstances, equitable remedies such as injunctive or
other forms of non-monetary relief will remain available under Oklahoma law.  In
addition, each director will continue to be subject to liability for breach of
the director's duty of loyalty to the Registrant, as well as for acts or
omissions not in good faith or involving intentional misconduct, for knowing
violations of law, for actions leading to improper personal benefit to the
director, and for payment of dividends or approval of stock repurchases or
redemptions that are unlawful under Oklahoma law.  The provision also does not
affect a director's responsibilities under any other law, such as the state or
federal securities laws.

     Under Section 1031 of the Oklahoma General Corporation Act, the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act of 1933, as amended (the "Securities Act").

     The Registrant's Certificate of Incorporation provides that the Registrant
shall indemnify its directors and officers to the fullest extent permitted by
Oklahoma law.  The Certificate of Incorporation requires the Registrant to
indemnify such person against expenses, judgments, fines, settlements and other
amounts incurred in connection with any proceeding, whether actual or
threatened, to which any such person may be made a party by reason of the fact
that such person is or was a director or an officer of the Registrant or any of
its affiliated enterprises, provided such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the Registrant, and, with respect to any criminal proceeding, had
no reasonable cause to believe his conduct was unlawful.  However, in the case
of a derivative action, an officer or director will not be entitled to
indemnification in respect of any claim, issue or matter as to which such person
is adjudged to be liable to the Registrant, unless and only to the extent that
the court in which the action was brought determines that such person is fairly
and reasonably entitled to indemnity for expenses.

     The Registrant has entered into Indemnification Agreements with each non-
employee director of the Registrant that require the Registrant to indemnify
such persons against certain liabilities and expenses incurred by any such
persons by reason of their status or service as directors of the Registrant.
The Indemnification Agreements also set forth procedures that will apply in the
event of a claim for indemnification under such agreements.  In addition, the
Indemnification Agreements require that the Registrant use commercially
reasonable efforts to maintain policies of directors' liability insurance.

     At present, there is no pending litigation or proceeding involving a
director or officer of the Registrant as to which indemnification is being
sought nor is the Registrant aware of any threatened litigation that may result
in claims for indemnification by any officer or director.

Item 22.  Undertakings.

     The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

     The undersigned Registrant undertakes that every prospectus (i) that is
filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to
meet the requirements of Section 10(a)(3) of the Act and is used in connection
with an offering of securities subject to Rule 415, will be filed as a part of
an amendment to the registration statement and will not be used until such
amendment is effective, and that, for purposes of determining any liability
under the Securities Act of 1933, each such post-effective amendment 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.

     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
or paid by a director, officer or controlling person of the Registrant 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 it is against public
policy as expressed in the Act and will be governed by the final adjudication of
such issue.

     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the Joint Proxy
Statement/Prospectus pursuant to Items 4, 10(b), 11 or 13 herein, within one
business day of receipt of such request, and to send the incorporated documents
by first class mail or other equally prompt means.  This includes information
contained in documents filed subsequent to the effective date of the
Registration statement through the date of responding to the request.

     The undersigned Registrant hereby undertakes to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in the
Registration Statement when it became effective.
