                                                                   JUNE 30, 1999


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 drilling at properties located
         in Kansas.

         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 general
         member to drill oil and gas wells. Under the terms of the contracts,
         the general member manages the drilling of the wells and the LLC pays a
         fixed cost per well working interest. The LLC advances funds to the
         general member in order to finance the drilling activity.

         Wells in Process - The Company uses the successful efforts method of
         accounting for its oil and gas working interests. Costs to acquire the
         working interests, which includes the LLCs proportionate share of
         acquisition, drilling and completion costs are capitalized. Capitalized
         costs of acquiring the working interests are depreciated and depleted
         by the u n it-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.

         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 revenue and expenses during the reporting period.
         Actual results could differ from those estimates.

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

                                                   NOTES TO FINANCIAL STATEMENTS
                                                                   JUNE 30, 1999

Note 2 - 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 interestholders pay
         approximately 95 percent of the cost of acquiring the working interests
         and the manager pays the remaining 5 percent of such costs. Intangible
         drilling costs are allocated 100 percent to the investor
         interestholders. Net profits from sales of production are allocated
         approximately 90 percent to the investor interestholders and 10 percent
         to the manager, until such time that the investor interestholders have
         recovered their investment in the LLC. Thereafter, net profits are
         allocated approximately 70 percent to the investor interestholders and
         30 percent to the manager.

         During 1999, the LLC incurred $379,4801 in costs under turnkey
         agreements to WELLC. Of this amount, $59,320 is included in accounts
         payable at June 30, 1999.

         In connection with the sponsorship of the LLC, WELLC is entitled to
         management fees of 2.5 percent from investor interestholder
         subscriptions, which are expensed when incurred. During 1999, the LLC
         paid WELLC $10,700 in management fees.

Note 3 - Cash Flows

         During 1998, the LLC acquired working interests in oil and gas wells
         that were still in process at the end of the period. Accounts payable
         includes $59,320 of these acquisition costs.

         The LLC received capital contributions totaling $449,400 during 1999
         and incurred syndication costs related to those contributions totaling
         $49,220, of which $10,140 are accrued at June 30, 1999.

ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.

         Management's discussion and analysis of financial condition and results
of operations should be read in conjunction with the financial statements and
notes thereto.

Six Months ended June 30, 1999

Financial Condition

         Liquidity and Capital Resources

As an passive investment entity, the registrant 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. The
registrant did not engage in operations during the three months ended June 30,
1999, and, therefore, did not realize any net cash flows from operating
activities during that period. The registrant's cash flows during the period
resulted from the net inflow of capital from the sale of interests in the
registrant to investors and payments by the registrant related to (i) turnkey
drilling and development arrangements made to an affiliate of the Manager, and
(ii) costs to unaffiliated parties related to the offering and sale of interests
in the registrant in a public offering. The registrant's sole present source of
liquidity is the proceeds of the sale of interests in the registrant. The
registrant will in the future generate liquidity from operations after it begins
to realize proceeds from the sale of natural gas production from wells in which
it owns a fractional working interest. The registrant has no commitments to
provide it with a lending facility from which it could borrow funds to provide
additional liquidity in the future.

The registrant realized gross proceeds from the sale of interests totaling
$449,400 in the period, of which $320,160 was paid to unaffiliated parties in
respect of wells in progress in which the registrant holds a fractional working
interest and $67,655 was paid to unaffiliated parties in respect of syndication
and offering costs for the offering and sale of interests.

The registrant has not entered into any new material commitments for capital
expenditures in excess of those which were funded during the period. The
registrant will undertake additional commitments for capital expenditures only
for new turnkey arrangements in respect of natural gas well development and
drilling activities and only then when it has received additional capital
contributions from investors from which to fund such commitments. The registrant
does not expect that it will undertake any capital commitments in excess of
capital contributions received in the foreseeable future. The availability of
capital resources and liquidity for the registrant is and will likely remain
closely tied to the level of prices for natural gas deliveries and price levels
generally, and the actual and perceived trends in changes thereof.

Results of Operations

The registrant is engaged in the development and operation of natural gas wells
and the sale of

<PAGE>   9


natural gas production therefrom. During the three months ended June 30, 1999,
the registrant entered into an agreement to acquire interests in natural gas
well development projects on a turnkey basis with an affiliate of the Manager
and made payments totaling $379,480 thereunder. The development of the projects
subject to such turnkey arrangements is proceeding under the supervision of an
operator which is not affiliated with the Manager or the registrant, but has not
yet been completed. Consequently, the registrant did not realize any revenues
from operations in the three months ended June 30, 1999. The registrant did
incur operating expenses during the period, primarily management fees and
professional expenses related to its organization, offering of interests and
management of its turnkey drilling activities. 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, and the actual and perceived
trends in changes thereof. However, the levels of operating expense related to
production of natural gas from wells in which the registrant owns a fractional
working 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.

ITEM 3.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

The registrant 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. The registrant 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 levels of consumer
demand, the price and availability of alternative fuels, the availability of and
proximity to pipelines, and changes in existing federal regulation 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 make it particularly difficult to estimate future
prices of gas, and any assumptions about future prices may prove incorrect.
