                          PDK LABS INC. AND SUBSIDIARY
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                      THREE MONTHS ENDED FEBRUARY 29, 2000

1.     Basis of Presentation:

      The interim condensed consolidated financial statements furnished reflect
all adjustments which are, in the opinion of management, necessary to present a
fair statement of the financial position, as of February 29, 2000 and the
results of operations and statements of cash flows for the three month periods
ended February 29, 2000 and February 28, 1999. The balance sheet as of November
30, 1999 has been derived from the audited balance sheet as of that date. This
report should be read in conjunction with the Company's annual report filed on
Form 10-K for the fiscal year ended November 30, 1999. The results of operations
and cash flows for the three month period ended February 29, 2000 are not
necessarily indicative of the results to be expected for the full year.

2.      Principles of Consolidation:

        The accompanying consolidated financial statements include the accounts
of PDK Labs Inc. ("PDK") and its subsidiary, Futurebiotics, Inc.
("Futurebiotics") (collectively the "Company"). All intercompany balances and
transactions have been eliminated.

3.      Concentration of Credit Risk:

        Financial instruments which potentially expose the Company to
concentrations of credit risk, as defined by Statement of Accounting Standards
No. 105, consist primarily of trade accounts receivable.

4.      Inventories:

         Inventories have been estimated by using the gross profit method for
the interim periods. The components of the inventories are as follows:

5.      Stockholders' Equity:

        Basic earnings per common share is computed by dividing the net earnings
after dividends on preferred shares by the weighted average number of shares of
common stock outstanding during the period. Dilutive earnings per share gives
effect to stock options which are considered to be dilutive common stock
equivalents. Certain options were not included in the computation due to their
exercise price exceeding the average market price of the common shares. Treasury
shares have been excluded from the weighted average number of shares. The
assumed conversion of the preferred stock and the related reduction to the
preferred stock was not included in the computation as the effect was
antidilutive. EPS was calculated for the three months ended February 29, 2000
and February 28, 1999 as follows:

                                   (Continued)

        Preferred stockholders are entitled to cumulative annual dividends of
$.49 per share, payable at the election of the Company in cash, common stock, or
a combination thereof. Such dividends are payable semi-annually on or about
April 15 and October 15 of each year. Dividends earned for each of the three
month periods ended February 29, 2000 and February 28, 1999 approximated $58,000
and $64,000, respectively.

        The Company's Board of Directors has authorized the Company's management
to repurchase up to $7,000,000 worth of its own common stock, par value $.01, in
the public market at such time or times, and at such prices, as management
believes appropriate. As of February 29, 2000, the Company had authorization to
repurchase an additional $344,000 worth of its own stock.

        In addition, the Company's Board of Directors authorized the management
to repurchase up to $500,000 worth of its own preferred stock, par value $ .01
in the public market. As of February 29, 2000, the Company had authorization to
repurchase an additional $261,000 worth of its own preferred stock.

6.      Income Taxes:

        Effective December 17, 1999, the Company and its subsidiary will file a
consolidated federal income tax return. The Company and its subsidiary each
report current and deferred income tax expense (benefit) under an allocation
method that results in a profitable company recognizing a tax provision as if
the individual company filed a separate return and loss companies recognizing
benefits to the extent their losses contribute to reduce consolidated taxes. In
addition, during the quarter ended February 29, 2000 the change in the valuation
allowance ($197,000) of the subsidiary's deferred tax asset resulting from its
ability to file a consolidated return with the Company was recorded as a tax
benefit on the books of the subsidiary.

      The consolidated current and deferred tax assets and liabilities are
recorded on the books of the Company, and the net tax-related balances due
to/from the subsidiary are included in the intercompany balance.
