                            REGENT TECHNOLOGIES, INC.
                          NOTES TO FINANCIAL STATEMENTS
                March 31, 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 of furniture and fixtures 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 tax purposes.

Income Taxes

The Company utilizes the method of accounting for income taxes 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 in 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 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 income per share of the Company.

Cash Equivalents

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

(3) TRANSACTIONS WITH RELATED PARTIES

During the first quarter, 1999, the Directors approved settlement agreements
with the Chairman, the President, the General Counsel, the Director of Marketing
and the Chief Technical Officer to terminate each of their employment contracts
and the deferred compensation amounts due thereunder.

The Chairman accepted a $90,000 promissory note for the $90,000 deferred
compensation owed. The promissory note was assigned to a third party and
redeemed by the Company with 900,000 shares of restricted Common Stock. In
addition, the Chairman agreed to accept conveyance of 100% of the ownership and
interests in Regent Digital Imaging, Inc. and ConnecTen, L.L.C. in exchange for
all other monies owed to the Chairman including $200,000 owed under a secured
line of credit and termination of his employment contract. From the assets of
the transferred companies, the Chairman agreed to pay certain Company payables,

Item 2. Management's Discussion and Analysis of Financial Conditions and Results
        of Operations

The statements contained in this Form 10-QSB that are not historical facts are
forward-looking statements (as such term is defined in the Private Securities
Litigation Reform Act of 1995) that involve risks and uncertainties. Such
forward-looking statements may be identified by, among other things, the use of
forward-looking terminology such as "believes," "expects," "may," "will,"
should" or "anticipates" or the negative thereof or other variations thereon or
comparable terminology, or by discussions of strategy that involve risks and
uncertainties. From time to time, the Company or its representatives have made
or may make forward-looking statements, orally or in writing. Such
forward-looking statements may be included in various filings made by the
Company with the Securities and Exchange Commission (the "SEC"), or press
releases or oral statements made by or with the approval of an authorized
executive officer of the Company. These forward-looking statements, such as
statements regarding anticipated future revenues, capital expenditures and other
statements regarding matters that are not historical facts, involve predictions.
The Company's actual results, performance or achievements could differ
materially from the results expressed in, or implied by, these forward-looking
statements.

Business and Acquisition Strategy

With the Company's decision to return to the landfill and waste related
businesses, the Company will seek to expand this business with the acquisition
of companies in markets where consolidations are an appropriate method for
long-term growth. The Company expects to initiate operation centers in four new
markets primarily by the acquisition of existing companies primarily with
issuance of the Company's restricted Common Stock.

Financial Condition

Liquidity and Capital Resources

At March 31, 1999, the Company had net working capital of $10,000. The Company
has no amortization requirements under any term loan agreements. The Company is
not current on its trade payables including amounts owed to officers and
affiliates. The Company continues to raise monies as needed through proceeds
from the sale of the Company's common stock.

Results of Operations

COMPARISION OF THE THREE MONTHS ENDED MARCH 31, 1999 TO THE THREE MONTHS ENDED
MARCH 31, 1998

     The Company's net loss for the three months ending March 31, 1999 was
$7,000 or $.002 cents per common share, compared with a net loss of $290,000 for
the same period in 1998. The $4,000 recorded as Other Income was due to the
receipt of 42,876 shares of Common Stock of the Company for the settlement of an
employee contract. A total of $10,000 was recorded as expense related to the
100,000 shares of Common Stock granted to settle employee related compensation.
The primary difference for the current three month period as compared to the
previous year was the decrease of general and administrative costs for the
current period.
