                          NOTES TO FINANCIAL STATEMENTS
                 June 30, 1999 (unaudited) and December 31, 1998


(1) BASIS OF PRESENTATION

The accompanying financial statements, which should be read in conjunction
with the financial statements of Regent Technologies, Inc. ("the Company")
included in the 1998 Annual Report filed on Form 10-KSB, are unaudited but
have been prepared in the ordinary course of business for the purpose of
providing information with respect to the interim period. The Company
believes that all adjustments (none of which were other than normal recurring
accruals) necessary for a fair presentation for such periods have been
included.

(2) ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Organization and Business

Regent Technologies, Inc., formerly Regent Petroleum Corporation, was
incorporated on January 18, 1980, for the purpose of exploration and development
of oil and gas properties in the United States. Activities of the Company up to
1992 were primarily organization, issuance of equity capital and acquisition of
developed and undeveloped oil and gas properties which included the formation of
Earth Minerals, Inc. in 1991, which was later renamed Regent Industries, Inc. In
1992, the Company redirected its core activities and acquired SSB Environmental,
Inc. ("SSBE"), which was organized for the purpose of obtaining waste and
landfill reclamation contracts and accounted for under the purchase method of
accounting. Effective January 1, 1996, the Company sold 100% of Regent
Industries and 81% of its interest in SSBE, and the remaining 19% was accounted
for on the cost method of accounting. In September, 1996, the Company entered
into a license agreement for the technologies necessary to offer dialup access
to the Internet (the "Technology License" or "License"). During the fourth
quarter of 1996, the Company organized Regent TEL1 Communications, Inc. ("TEL1")
as a Nevada corporation and a wholly owned subsidiary to market its Internet
products and services primarily to consumer markets. In the third quarter of
1997, the Company acquired ConnecTen, L.L.C. as a wholly owned subsidiary to
market its dedicated Internet access services to professionals and corporations.
Effective January 1, 1998, the Company acquired Channel Services, LC, to expand
its telecommunications products to include wireless telephone services. The
acquisitions of ConnecTen and Channel Services were accounted for under the
purchase method of accounting. During the first quarter of 1998, the Company
organized Regent Digital Imaging, Inc. to offer digital printing and prepress
services with access available via the Internet. Effective January 1, 1998, the
Company divested 100% of its ownership in all subsidiary companies. The
investment in SSBE was written off without value as of December 31, 1998.

Depreciation

Depreciation is provided in amounts sufficient to relate the cost of depreciable
assets to operations over their estimated service lives (5 years). The
straight-line method of depreciation is used for financial reporting purposes,
while accelerated methods are used for federal income tax purposes.

Income Taxes

The Company utilizes the method of accounting for federal income tax set forth
in Statement of Financial Accounting Standards No. 109 "Accounting for Income
Taxes" (SFAS 109). SFAS 109 requires the recognition of deferred tax liabilities
and assets for the expected future tax consequences of events that have been
recognized in the Company's financial statements or tax returns. Under this
method, deferred tax liabilities and assets are determined based on the
difference between the financial statement carrying amounts and tax bases of
assets and liabilities, using enacted tax rates in effect in the years which the
differences are expected to reverse. These temporary differences primarily
relate to depreciation, depletion and amortization. The Company has not
recognized the benefit of any net operating loss carryforwards as the result of
adopting SFAS 109, and no deferred tax assets have been recorded on the books of
the Company due to uncertainty as to the Company's ability to utilize the loss
carryforwards.

Loss Per Share

Loss per share is based on the weighted average number of common shares
outstanding for each period presented. Common Stock equivalents are included if
dilutive. In February 1997, the Financial Accounting Standards Board issued
Statement No. 128, "Earnings per Share," which is required to be adopted for
years ending after December 15, 1997. Under the new requirements for calculating
primary earnings per share, the dilutive effect of stock options and warrants
will be excluded. Statement No. 128 is not expected to have a material impact on
the net loss per share of the Company.

Cash Equivalents

The Company does not consider any of its assets to meet the definition of a cash
equivalent.

     The Company's net loss for the six months ending June 30, 1999 was $14,000
or $.003 cents per common share, compared with a net loss of $493,000 for the
same period in 1998. The $4,000 recorded as Other Income was due to the receipt
of 42,876 shares of restricted Common Stock for the settlement of an employment
contract. A total of $10,000 was recorded as expense related to the 100,000
shares of restricted Common Stock issued to fulfill previous commitments. The
