                               CADEMA CORPORATION
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  SIX MONTHS IN THE PERIOD ENDED JUNE 30, 1998

(1)  NATURE OF BUSINESS AND CURRENT OPERATING ENVIRONMENT:

     The principal business of Cadema Corporation (the "Company") is the
     financing and operating of business enterprises with the potential to
     generate profits and cash flow. Currently the Company is exploring possible
     acquisitions and mergers throughout the United States and abroad, as it has
     done in the past, seeking to enter into new operating businesses and to use
     the Company's liquid assets in connection therewith. As part of this
     strategy, the Company entered into a joint venture agreement with Global
     Environmental, Inc. in December 1993. The Company did not generate any
     revenues from operations in 1998 or 1997, and is currently pursuing
     additional contracts.

     While the principal business of the Company is the financing and operating
     of business enterprises with the potential to generate profits and cash
     flow, it still intends to invest in and sell marketable securities as
     outlined in a plan approved by stockholders in 1988.

     The Company intends to continue to invest in trading securities, including
     but not limited to stocks, bonds, options and warrants.

     The Company now holds and currently expects to invest primarily in the
     stock of smaller, lesser known and often more speculative companies, which
     while entailing above-average risk, offer the potential of above-average
     reward.

     There are significant risk factors affecting the Company, including
     potential operating losses it may incur from operating ventures, the
     volatility of market values of its investment securities portfolio, and the
     possible need for additional capital. These and other factors may adversely
     affect the Company's future operations.

(2)  SIGNIFICANT ACCOUNTING POLICIES

     CASH AND CASH EQUIVALENTS

     For purposes of the Consolidated Balance Sheet and Statements of Cash
     Flows, the Company considers its short-term investments purchased with a
     maturity of three (3) months or less to be cash equivalents.

     REVENUES

     Revenues are the result of contract revenues recognized utilizing the
     percentage of completion method of accounting. Contract revenues are the
     total of contract costs, which include all direct material and labor costs
     and those indirect costs related to contract performance, and provisions
     for estimated gain or loss on the contracts. The provisions for estimated
     gain or loss on the contracts are adjusted during the period in which the
     Company first becomes aware of the need for a change.


                                        7


<PAGE>   8


(2)  SIGNIFICANT ACCOUNTING POLICIES: (CONT.)

     REVENUES (CONT.)

     Total estimated costs are periodically revised, if necessary, to reflect
     changes to the original contracts and changes to total estimated contract
     costs based on deviations of actual cost to date from original estimates
     and anticipated future deviations from such original estimates. Selling,
     General and Administrative costs are charged to expense as incurred.

     TRADING SECURITIES

     Effective January 1, 1994 the Company adopted Statement of Financial
     Accounting Standards (SFAS) ("Statement") No. 115, "Accounting for Certain
     Investments in Debt and Equity Securities." The Company's adoption of the
     Statement requires its marketable securities to be classified as "trading"
     and accounted for at fair market value, with unrealized gains and losses
     reported as a component of net income (loss).

     Realized gains and losses are determined on a first-in, first-out basis.

     NET INCOME (LOSS) PER SHARE BASIC AND DILUTED

     Net income (loss) per share is calculated in accordance with SFAS No. 128.
     Basic earnings per share is calculated using net income less preferred
     stock dividend, divided by the weighted overage number of shares of common
     stock outstanding during the period, stock options outstanding are not
     included. Diluted earning per share extends this calculation to include the
     dilutive effect of preferred stock, options and warrants. Currently all
     Cadema preferred stock, options and warrants have an anti-dilutive effect,
     which by rule excludes them, and result in the two per share definitions
     being equal for this period.

(3)  JOINT VENTURE:

     On December 31, 1993 the Company entered into a Joint Venture Agreement
     with Global Environmental, Corp., a New York corporation, to create the
     Joint Venture entity Global Environmental Offshore Company ("Global" or
     "Joint Venture"). The Joint Venture Company engages in contracting for the
     design and installation of Air Pollution Control equipment and facilities
     in areas located outside the United States. Under the terms of the Joint
     Venture Agreement, the Company contributed $350,000 and received 51%
     control of the Joint Venture.

     Under the Joint Venture Agreement, Global Environmental, Corp. has the
     right to acquire the Company's interest in the Joint Venture for, at the
     Company's option, 875,000 shares of Global stock or the greater of $350,000
     or the Company's existing capital account. The Company has the option to
     convert its Joint Venture interest into 875,000 shares of Global
     Environmental, Corp.'s common stock.


                                        8

(3)  JOINT VENTURE: (CONT.)

     The financial statements of the Joint Venture are consolidated with the
     Company's results in the accompanying financial statements of this report.
     The portion of the Joint Venture's income that is not applicable to the
     Company is recorded as Minority Interest on the Statement of Operations.
     That income along with Global Environmental Corp.'s capital contribution to
     the Joint Venture is recorded under the caption "Minority Interest in
     Subsidiary" on the Balance Sheet.

     Notes payable issued by Global Environmental Corp. to the Joint Venture are
     carried on the Balance Sheet as Notes Receivable and were due on December
     31, 1996. Negotiations are in process for the refinancing of the note. As
     collection of the note in 1998 is not likely, the note has been classified
     as long-term.

     Negotiations are in process for the refinancing of this note receivable.
     Global Environmental Corp. does not have funds available to repay the Note
     in cash and has offered to exchange its stock for the Note. The Company has
     established a 70% reserve against the carrying value of the Note in
     recognition of the potential costs involved in liquidating any noncash
     settlement of this Note. Although the Company believes such 70% reserve to
     be adequate, the reserve is an estimate based on information presently
     available. The Company's estimate could change, which would result in a
     change in the reserve in the future.

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

     The principal business of Cadema Corporation (the Company) is the financing
     and operating of business enterprises with the potential to generate
     profits and cash flow. Currently the Company's sole operating subsidiary,
     Global Environmental Offshore Company, engages in contracting for the
     design and installation of Air Pollution Control equipment and facilities
     for international markets. The Company continues to explore possible
     acquisitions and mergers as it has done in the past, seeking to enter into
     new operating situations with it can utilize its liquid assets.

     While the principal business of the Company is the financing and operating
     of business enterprises with the potential to generate profits and cash
     flow, it still intends to invest in and sell marketable securities as
     outlined in a plan approved by stockholders in 1988.

     RESULTS OF OPERATIONS

     There were no revenues in the first six months of 1998, as the Company's
     operating subsidiary Global Environmental Offshore Company had no revenue
     activity. In 1997, the operating activity of Global Environment Offshore
     Company produced no revenues in the same period.

     Operating expenses for the first six months of 1998 were $17,340 and
     represented administrative expenses of the parent Company. These expenses
     exceeded 1997 first half operating expense of $12,982.

     Other income in this first half totaled a loss of $112,376 as compared to a
     1997 loss of $130,689. This contrast is due to a larger unrealized loss on
     the company's Investment Portfolio in 1997 as compared to the same period
     of 1998.

     The net loss applicable to common stock for the first half, after an
     accrual for a Preferred Stock dividend, was $214,267 or $.02 per share. For
     the same period of the prior year, a comparable loss of $228,562 or $.02
     per share was recognized.

     LIQUIDITY AND CAPITAL RESOURCES

     Liquidity and working capital decreased by $129,376 to $406,504 in the
     first half of 1998 due primarily to the performance of the Company's
     marketable securities portfolio.

     The Company believes it has sufficient working capital to meet its
     liquidity needs over the next twelve months.
