            WOLVERINE ENERGY 1998-1999(A) DEVELOPMENT COMPANY, L.L.C.

                          NOTES TO FINANCIAL STATEMENTS
                                 MARCH 31, 2001

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 and 2000, the LLC advanced monies for re-completion at properties
         located in Kansas. By the end of 2000, the LLC had 36 net well
         interests in 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 entered into contracts with the Manager to
         drill gas wells. Under the terms of the contracts, the Manager managed
         the drilling of the wells and the LLC paid a fixed cost per well
         working interest. The LLC advanced 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 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, 2000, all of the Wells in which the LLC owns an
         interest were completed and in production. 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.
         The Manager participated in a joint venture that acquired the pipeline
         in 2000. In the first quarter of 2001, the joint venture undertook
         certain improvements to the pipeline. Nonetheless, the volume of
         production is still not meeting expectations, and the Manager is
         engaged in further study of the wells and their infrastructure.

NOTE 3 - RELATED PARTY TRANSACTIONS

         The LLC had acquired working interests in 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 required the investor interest holders to pay
         approximately 95 percent of the cost of acquiring the working interests
         and the Manager to pay 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, $62,039 and $173,993,
         respectively, is included in accounts payable at March 31, 2001 and
         2000.

         WELLC advanced $90,791 to the LLC during the first quarter of 2001. The
         balance sheet also reflects advances from WELLC to the LLC made in 2000
         in the amount of $67,725. These amounts are due on demand.

NOTE 4 - CASH FLOWS

         The LLC still owes money associated with the expense of acquiring the
         gas well working interests and drilling expense that were incurred in
         1999 and 2000. Accounts payable includes $62,039 and $173,993,
         respectively for this purpose, at March 31, 2001 and 2000. Accounts
         payable for operations were $18,778 and $0 respectively at March 31,
         2001 and 2000.

                            WOLVERINE ENERGY, L.L.C.
                          Notes to Financial Statements
                                 March 31, 2001

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 and land leases 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 interests and land leases have been
         impaired. If impairment exists, a loss is recognized by recording an
         impairment allowance. Abandonments of working interests and land leases
         held for resale are charged to expense. As of March 31, 2001 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 Drilling Revenue - 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
         March 31, 2001 and 2000, 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.

         Organizational Fees - In connection with the organization and offering
         stage of related oil and gas entities, WELLC may receive an
         organizational fee ranging from 1.0 to 2.5 percent from investor




                                       11
<PAGE>   12

         subscriptions, which is credited to income as earned.

         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 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
         companies, 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
         at March 31:

         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 March 30, 2001, WELLC currently has one offering it is soliciting
         with a maximum investor contribution limit of $6,000,000. WELLC is
         required to match every capital contribution from an investor with a
         capital contribution of one percent of the investor contribution. If
         maximum investor contributions are obtained, WELLC is committed to
         purchase an additional $60,000 in limited company memberships.

         In the first quarter of 2001, WELLC guaranteed 20 percent of the
         outstanding $3,100,000 in debt of a related party, for a total of
         $620,000.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS


         This discussion should be read in conjunction with the financial
statements and accompanying notes.

                PROGRAM A - FOR THE PERIOD ENDING MARCH 31, 2001

RESULTS OF OPERATIONS

         During the three months ending March 31, 2001, Program A sold 977 mcf
         of gas at an average price $7.08 per mcf, compared to the sale of 201
         mcf at an average price of $2.08 per mcf during the first three months
         of 2000. Revenues from operations were $6,934 during the first quarter
         of 2001, compared with $418 during the first quarter of 2000.

         Operating expenses averaged $7.01 per mcf during the first three months
         of 2001 compared to $4.57 per mcf during the first three months of
         2000. This is reflected in well operating fees for the first three
         months of 2001 of $6,851 compared with $919 for the first three months
         of 2000. The reason for this significant increase in operating expenses
         during the year 2001 was the very cold conditions in the field, which
         caused freezing problems at the wells and created difficulty in keeping
         the compressors running. It is impossible to predict from year to year
         how severe winter weather conditions will be and what impact that may
         have on operating expenses.

         Other expenses during the first quarter of 2001 were significantly
         greater than the first quarter of 2000. For example, a depreciation and
         depletion expense of $4,000 was recorded for the first quarter of 2001.
         Because the wells were not yet in production during the first quarter
         of 2000, there was no depreciation and depletion expense recorded in
         the first quarter of 2000. In addition, professional fees were
         significantly higher in the first three months of 2001 ($21,003
         compared with $2,729 in the first three months of 2000). This
         difference in expense levels for professional fees is explained in part
         by the fact that the Company's financial statements for the year 1999
         were completed late in the year of 2000, with invoices paid during the
         first quarter of 2001. Additional legal fees were also recorded because
         of certain regulatory problems associated with the Company's reliance
         on prior counsel to register the offering of memberships in Program A
         with certain state regulatory offices and the later discovery that this
         had not occurred in some cases. Expenses for general and administrative
         were recorded at $7,886 in the first quarter of 2000, as compared to
         $11,897 in the first quarter of 2001. This $4,001 variance reflects the
         cost of the engineering report for the evaluation of reserves. An
         engineering report will be obtained annually from this point forward at
         an anticipated annual cost of $4,000 to $6,000.

         As reflected in the Company's 10-KSB for the fiscal year ending
         December 31, 2000, CB Pipeline, L.L.C., which is owned 50 percent by
         affiliates of the Manager and 50 percent by Spartan Energy, Ltd.,
         purchased Great Eastern Pipeline, which is intended to service the
         wells in Program A. During the first quarter of 2001, CB Pipeline,
         L.L.C. replaced two compressors associated with the pipeline, including
         the main compressor at the Williams Tap. While there has been some
         improvement in overall volumes, the response has not met the Manager's
         expectations. Accordingly, the Manager has contracted with Bach
         Enterprises, an independent third party based in Kalkaska, Michigan, to
         review all of the wells and infrastructure in the Independence
         Prospect, which is



                                       15
<PAGE>   16

         where all of the wells owned by Program A are located. Bach
         Enterprises' report is expected to be received in late summer or early
         fall of 2001, and will provide the basis for any additional steps to be
         taken with a goal of improving results.

         Natural gas prices reached an all-time high of close to $10 per mcf in
         January, 2001. By March 2001, gas prices had fallen to an average of
         $3.91 per mcf. Various factors beyond the control of Program A and the
         Manager will affect prices of gas in the future including, but not
         limited to, the world wide supply of gas, political instability or
         armed conflict in gas-producing regions, the price of foreign imports,
         the levels of consumer demand, the price and availability of
         alternative fuels, and changes in existing federal regulations and
         price controls. Prices for gas have historically fluctuated greatly,
         and markets for gas 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
         to be inaccurate. Nonetheless, the Manager does anticipate that gas
         prices will probably be higher during the winter heating season than
         during periods of warmer weather.

         Under Program A's operating agreement, the Manager is entitled to
         receive an administrative cost allowance. The Manager is allowed to
         waive or defer the administrative cost allowance. For the first quarter
         of 2001, the Manager has elected to waive its administrative cost
         allowance from Program A. Accordingly, no liability was booked for this
         expense.

LIQUIDITY AND CAPITAL RESOURCES

         During the first quarter of 2001, Program A's cash flow from operations
         was $(16,538), compared to $8,730 in 2000. This difference was caused
         predominantly by the higher operating costs created by the cold
         weather, as reflected in the discussion above.

         Program A continues to owe the Manager $62,039 as the balance due on
         the turnkey price payable to the Manager for the well interests
         purchased by Program A. This compares to a balance owed to the Manager
         for the turnkey price of $173,993 owed as of March 31, 2000. The
         Manager has made advances to Program A to permit distributions to the
         investors. These advances are payable on demand. During the first
         quarter of 2001, the Manager advanced $90,791 to Program A, and Program
         A made distributions to members equal to $70,778. Program A continues
         to experience shortages of cash flow due to unexpectedly low
         production. To date, shortfall has been satisfied through advances from
         the Manager. Program A does not have any line of credit or similar debt
         facility.

               THE MANAGER - FOR THE PERIOD ENDING MARCH 31, 2001

RESULTS OF OPERATIONS


         Total turnkey revenues earned by the Manager have risen significantly.
         During the first quarter of 2000, turnkey revenues were $568,030.
         During the first quarter of 2001, turnkey revenues were $2,078,281,
         reflecting an increase of $1,510,251 or 366 percent. Costs of sales
         associated with the turnkey revenues also increased significantly from
         $500,028 in the first quarter of 2000 to $1,603,834 in the first
         quarter of 2001. This is a difference of $1,103,806 or 321 percent.
         There was a resulting increase in gross margin from 11.97 percent in
         the first quarter of 2000 to 22.82 percent in the first quarter of
         2001.

         The Manager also experienced a significant increase in general
         administrative expense, from $373,730 in the first quarter of 2000, to
         $983,517 in the first quarter of 2001, an increase of $609,787, or 263
         percent. This increase reflects the Manager's focus on growing the
         business during a period of strong demand for natural gas. In addition,
         because of the substantial number of programs now under management by
         the Manager, additional administrative personnel support had to be
         added. There was also a significant increase in expenditures for
         travel.

         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 investments in natural gas investment programs.

LIQUIDITY AND CAPITAL RESOURCES

         At March 31, 2001, the Manager had $99,622 in cash and cash equivalents
         available. This compares with $126,367 available at March 31, 2000. The
         Manager has a line of credit in the amount of $325,000, which had not
         been drawn on at March 31, 2000, but which has been entirely drawn down
         as of March 31, 2001. While the Manager's accounts payable have
         increased substantially as of March 31, 2001 ($5,426,218) compared to
         March 31, 2000 ($1,711,823), the Manager's accounts receivable have
         also increased substantially (March 31, 2001 of $2,721,454 compared to
         March 31, 2000 of $1,056,765). The accounts receivable at March 31,
         2001 are all due on demand and include amounts due from related
         entities in the amount of $2,272,106 and an account receivable from the
         Manager's member for a loan advance in the amount of $238,000. The
         Manager does not contemplate having to borrow additional moneys or open
         an additional line of credit.
