            WOLVERINE ENERGY 1998-1999(A) DEVELOPMENT COMPANY, L.L.C.
                          NOTES TO FINANCIAL STATEMENTS
                                  June 30, 2000

     NOTE 1 - NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Wolverine Energy 1998-1999(A) Development Company, L.L.C. (the LLC) was
organized on May 30, 1998 under the laws of the State of Michigan to engage in
oil and gas exploration, drilling, production and sales of natural gas at
properties located throughout the United States. During 1999, the LLC advanced
monies for re-completion at properties located in Kansas. In the first quarter
of 2000, work was completed on the wells and efforts began to tie the wells in
to production.

Cash and Cash Equivalents - The LLC considers all liquid investments purchased
with an original maturity date of three months or less to be cash and cash
equivalents.

Turnkey Agreements - The LLC enters into contracts with the Manager to drill oil
and gas wells. Under the terms of the contracts, the Manager manages the
drilling of the wells and the LLC pays a fixed cost per well working interest.
The LLC advances funds to the Manager in order to finance the drilling activity.

Wells in Process - The LLC uses the successful efforts method of accounting for
its oil and gas working interests. Costs to acquire the working interest, which
include the LLC's proportionate share of acquisition, drilling and completion
costs, are capitalized. Capitalized costs of acquiring the working interests are
depreciated and depleted by the unit of production method once the wells are
completed. Costs to acquire working interests that do not find proven reserves
are expensed.

Income Taxes - No provision for Federal income taxes has been included in the
financial statements since all income and expenses of the LLC are allocated to
the members in their respective Federal income tax returns.

Fair Value of Financial Instruments - The fair value of short-term financial
instruments, including cash and cash equivalents, accounts receivable and
accounts payable, approximate their carrying value in the financial statements
due to the short maturity of such instruments.

Syndication - Costs and expenses incurred by the LLC in connection with
syndication have been charged to members' equity.

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 these estimates.

NOTE 2 - STATUS OF WELLS IN PROCESS

         As of December 31, 1999, approximately 70 percent of the wells the LLC
         owns an interest in were drilled, with the remaining 30 percent being
         completed during the first three months of 2000. The wells are
         connected to a pipeline that is experiencing mechanical restraints and
         capacity limitations that affect the amount of gas that can flow from
         the wells. Subsequent to December 31, 1999, the Manager began
         negotiations to acquire the pipeline.

NOTE 3 - RELATED PARTY TRANSACTIONS

         The LLC acquires working interests in oil and gas properties. Wolverine
         Energy, L.L.C. (WELLC) serves as manager for the LLC and, as such, has
         full and exclusive discretion in the management and control of the LLC.
         The operating agreement provides that investor interest holders pay
         approximately 95 percent of the cost of acquiring the working interests
         and the Manager pays the remaining five percent of such costs.
         Intangible drilling costs are allocated 100 percent to the investor
         interest holders. Net profits from sales of production are allocated
         approximately 90 percent to the investor interest holders and 10
         percent to the Manager; until such time that the investor interest
         holders have recovered their investment in the LLC. Thereafter, net
         profits are allocated approximately 70 percent to the investor interest
         holders and 30 percent to the Manager.

         During 1999, the LLC incurred $1,937,629 in costs under turnkey
         agreements to WELLC. Of this amount, $58,065 and $59,320, respectively,
         is included in accounts payable at June 30, 2000 and 1999.

         In connection with the sponsorship of the LLC, WELLC is entitled to
         management fees of two and one-half percent from the investor interest
         holder subscriptions, which are expensed when incurred. During 1999,
         the LLC paid WELLC $53,109 in management fees.

NOTE 4 - CASH FLOWS

         During 1999, the LLC acquired working interests in oil and gas wells
         that were still in process at year-end. Accounts payable includes
         $58,065 and $59,320 respectively, at June 30, 2000 and 1999.

                            WOLVERINE ENERGY, L.L.C.
                          NOTES TO FINANCIAL STATEMENTS
                                  June 30, 2000

         Note 1 - Nature of Business and Significant Accounting Policies
         Wolverine Energy, L.L.C. (WELLC) acquires working interests in natural
         gas prospects throughout the United States, forms oil and gas entities
         and sells them the interests on a turnkey basis. WELLC is responsible
         for managing the operations of the entities.

         Working Interests Held for Resale - WELLC has acquired certain oil and
         gas working interests for the purpose of selling these interests to oil
         and gas entities. Such working interests held for resale are recorded
         at cost, but are periodically reviewed to determine if the market value
         of the working interest has been impaired. If impairment exists,
         recording an impairment allowance recognizes a loss. Abandonments of
         working interests held for resale are charged to expense. As of June
         30, 2000 no reserve for impairment has been recorded.

         Investments in Related Entities - Investments in related entities are
         accounted for under the equity method since WELLC has significant
         influence over the management of these entities. WELLC is the manager
         of the oil and gas entities and makes initial capital contributions in
         accordance with provisions in the respective placement memorandum or
         prospectus governing the activities of the particular entity. Income or
         losses are allocated to the investment accounts according to WELLC's
         ownership interest in the entities. Distributions received are deducted
         from the investment accounts.

         Turnkey Agreements - WELLC enters into contracts with affiliated
         entities to sell them oil and gas working interests under turnkey
         drilling agreements. Under the terms of the agreements, the entities
         pay a fixed price for acquisition, drilling and completion costs and
         receive working interests in the wells. WELLC agrees to monitor the
         well operators' obligation to conduct the drilling and completion of
         each well. Turnkey revenue is recognized when the related services have
         been performed (working interests have been sold) and substantially all
         future obligations have been settled.

         Cost of Sales - The Company acquires oil and gas working interests for
         resale that require the Company to pay a pro rata portion of all costs
         to drill and complete a well. The Company sells these oil and gas
         working interests in the wells at a fixed price, generally before the
         drilling is completed. Actual costs to drill and complete a well may
         exceed the sales price. The Company has the burden of paying all costs
         in excess of the turnkey price. Included in the accounts payable at
         June 30, 2000 and 1999, and cost of sales, is the estimated total cost
         that the Company will be required to pay on working interests that have
         been sold. Due to the uncertainties inherent in the estimation process,
         it is at least reasonably possible that the Company may incur expenses
         in excess of the amount recorded. Management is of the opinion that any
         adjustment of the amount recorded would not have a material adverse
         effect on the financial statements.

         Management Fees - In connection with the organization and offering
         stage of related oil and gas entities, WELLC may receive a management
         fee, an organizational and offering cost allowance and/or an
         organizational fee. Fees and cost allowances are credited to income as
         earned.



                                       12

<PAGE>   13


         Equipment - Equipment is recorded at cost. Depreciation is computed
         using straight line and accelerated methods over the estimated useful
         lives of the assets. Costs of maintenance and repairs are charged to
         expense as incurred.

         Income Taxes - No provision for Federal income taxes has been included
         in the financial statements since all income and expenses of WELLC are
         allocated to the member in his respective Federal income tax return.

         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 these estimates.

NOTE 2 - AFFILIATED OIL AND GAS ENTITIES

         WELLC sponsors the formation of entities, typically limited liability
         corporations, for the purpose of conducting oil and gas exploration,
         development and production activities on oil and gas properties. WELLC
         serves as manager of these entities and, as such, has full and
         exclusive discretion in the management and control. The turnkey
         drilling and operating agreements that WELLC enters into with the
         entities provide that the entities pay for the drilling costs of the
         wells at an agreed upon price per well. Profits from oil and gas
         properties are allocated based on the working interest ownership
         percentage of the properties.

         WELLC holds the following investment interest in the following
         entities:

NOTE 5 - RELATED PARTY TRANSACTIONS

         Because of the nature of WELLC's business, a significant number of
         transactions are with related parties. During the first two quarters of
         2000 and 1999, WELLC earned turnkey revenue from related entities in
         the amount of $2,608,374, and $904,992, respectively. The balance of
         turnkey revenues and allocated expenses owed to WELLC included in
         accounts receivable at June 30, 2000 and 1999 totaled $1,829,251 and
         $164,464, respectively.

NOTE 6 - COMMITMENTS AND CONTINGENCIES

         As managing member in various affiliated oil and gas entities, WELLC is
         subject to contingencies that may arise in the normal course of
         business of those entities. Management is of the opinion that
         liabilities, if any, related to such contingencies that may arise would
         not be material to the financial statements.

         As of June 30, 2000, WELLC has two offerings it is soliciting with a
         combined maximum investor contribution limit of $9,100,000. WELLC is
         required to match every capital contribution from an investor with a
         capital contribution ranging from one and one-half to five percent of
         the investor contribution. If maximum investor contributions are
         obtained, WELLC is committed to purchase an additional $210,000 in
         limited company memberships.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS


                 PROGRAM A - FOR THE PERIOD ENDING JUNE 30, 2000

FINANCIAL CONDITION

         Liquidity and Capital Resources - As a passive investment entity,
         Program A does not engage in active operations of the sort which
         require it to maintain liquidity beyond that required to pay its
         operating costs as they occur. Such operating costs are a small
         percentage of the capital, which it invests in relatively illiquid
         fractional working interests in natural gas well development projects.
         Program A engaged minimally in operations during the six months ending
         June 30, 2000 and recognized minimal cash flows during the period.
         Program A's cash flow during the period was derived from operating
         activities and interest income and outflows for administrative and
         operating expenses. Program A will, in the future, generate additional
         liquidity from operations after additional wells are connected to the
         pipeline and the mechanical constraints on the pipeline are resolved.
         Program A has no commitments to provide it with a lending facility from
         which it could borrow funds to provide additional liquidity in the
         future.

RESULTS OF OPERATIONS

         Program A is engaged in the development and operation of natural gas
         wells and the sale of natural gas production therefrom. During the six
         months ending June 30, 2000, income and expenses were recognized from
         initial operations. The level of revenues from operations will increase
         as additional wells are tied in to the sales pipeline and as mechanical
         restraints are removed from the pipeline. The level of revenues from
         operations of the registrant will be closely tied to the level of
         prices for natural gas deliveries and price levels generally. However,
         the levels of operating expenses related to production of natural gas
         from wells in which the registrant owns a fractional interest may not
         always change in response to economic conditions generally, resulting
         in diminished levels of profitability in periods of decreasing natural
         gas prices without corresponding decreases in operating costs.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         Program A is indirectly engaged exclusively in the development and
         operation of natural gas wells as an owner of fractional working
         interests therein. Such wells are developed and operated by
         unaffiliated parties who have primary responsibility for and control of
         the production and marketing of natural gas therefrom. Program A is,
         therefore, entirely subject to fluctuations in the value of its share
         of the natural gas production from such wells, which are reflective of
         the greater market for natural gas and the cost of transportation
         thereof. Various factors beyond the control of the registrant will
         affect prices of gas and natural gas liquids, including but not limited
         to, the worldwide supply of gas, political instability or armed
         conflict in gas-producing regions, the price of foreign imports, the




                                       16

         levels of consumer demand, the price and availability of alternative
         fuels, the availability of and proximity to pipelines and changes in
         existing Federal regulations and price controls. Prices for gas have
         historically fluctuated greatly and markets for gas and natural gas
         liquids continue to be volatile. The generally unsettled nature of
         energy markets makes it particularly difficult to estimate future
         prices of gas and any assumptions about future prices may prove
         inaccurate.


                THE MANAGER - FOR THE PERIOD ENDING JUNE 30, 2000

RESULTS OF OPERATIONS

         Net loss for the first half of 2000 was $650,579 as compared to
         $484,798 for the first half of 1999. Although turnkey revenues have
         risen substantially, cost of goods sold has risen disproportionately.
         This is because well interests for new projects are located in a very
         active area with resultant higher costs.

         The natural gas investment programs organized by the Manager have not
         begun to generate sufficient levels of production to result in
         meaningful distributions of operating profits to the Manager. Therefore
         the Manager has not recognized a meaningful level of profits from its
         interests in such programs.

         Total turnkey expenses and related costs increased 218 percent
         ($1,417,006) while turnkey revenues have increased only 188 percent
         ($1,703,382) resulting in a decrease in profit margin to 20.79 percent
         from 28.29 percent. General and administrative expense increased 54.27
         percent, reflecting the higher level of capital raising through
         affiliated natural gas investment programs and the cumulative effect on
         the level of administrative efforts of the new capital to the capital
         already under management.

WORKING INTERESTS HELD FOR RESALE

         Historically high prices for natural gas have piqued investor interest
         in direct investment in natural gas development. The Manager's sales
         for the first half of the year are at record levels. In anticipation of
         the continuation of this trend, the company has acquired a significant
         acreage position in the Wyoming Powder River Basin to ensure
         availability of product through 2002.
