                          NOTES TO FINANCIAL STATEMENTS

1.       Basis of presentation

         The balance sheets of Diapulse Corporation of America as of March 31, 
1999, and as of December 31, 1998, the related statements of income and cash
flows for the three months ended March 31, 1999 and 1998 have been prepared by
the Company without audit. In the opinion of management, all adjustments (which
included only normal recurring adjustments) necessary to present fairly the
financial position, results of operations and changes in cash flows for the
three months ended March 31, 1999 and 1998 and for all periods presented have
been made. Certain information and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been omitted. It is suggested that these financial statements be
read in conjunction with the financial statements and notes thereto included in
the Company's December 31, 1998 annual report to shareholders. There have been
no changes of significant accounting policies since December 31, 1998. Results
of operations for the three month period ended March 31, 1999 are not
necessarily indicative of the results that may be expected for the year ending
December 31, 1999.

2.  Principles of Consolidation

         The consolidated financial statements as of and for the three (3)
months ended March 31, 1999 include the accounts of the Company and its wholly
owned subsidiary DCA Healthcare. All significant intercompany accounts and
transactions have been eliminated in consolidation.

3.  Income Taxes

         The Company accounts for income taxes under the asset and liability
method.

4.  Inventories

         Inventories as of  March 31, 1999 and December 31, 1998 consisted
of the following:

5.       Basic and diluted Loss per Common Share

         Effective December 31, 1997, the Company adopted Statement of Financial
Accounting Standards No. 128, "Earnings Per Share," which required the
presentation of basic earnings per share and diluted earnings per share for all
periods presented. Basic earnings per share is based on the weighted average
number of outstanding common shares for the period. Diluted earnings per share
adjusts the weighted average for the potential dilution that could occur if
stock options, warrants, or other convertible securities were exercised or
converted into common stock. Diluted earnings per share equals basic earnings
per share for all periods presented because the effect of such items was
anti-dilutive.

6.  New Accounting Standards

         In June 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 130, "Reporting Comprehensive Income," and
Statement of Financial Accounting Standards No. 131, "Disclosures about Segments
of an Enterprise and Related Information," which are both effective for the year
ending December 31, 1998. SFAS No. 130 establishes standards for reporting
comprehensive income in a full set of general purpose financial statements
either in the income statement or in a separate statement. SFAS No. 131
establishes standards for reporting information about operating segments,
including related disclosures about products and services, geographic areas and
major customers. The Company has adopted SFAS No. 130 during the first quarter
of 1998 and has no items of comprehensive income to report.

In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities." This Statement requires that any entity recognize all
derivatives as either assets or liabilities in the statement of financial
position and measured those instruments as fair value. The Company will be
required to adopt this new accounting standard by January 1, 2000. Management
does not anticipate early adoption. The Company believes that the effect of
adoption of SFAS No. 133 will not be material

                 DIAPULSE CORPORATION OF AMERICA AND SUBSIDIARY

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF

                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Results of Operations

         Net sales for the current three months decreased by $82,821 to $309,671
from last year's comparable three month period of $392,492. This was due
primarily to a decrease in Medicare machine rentals in the Florida and New York
regions.

         Operating expenses for the current three months increased to $373,680
from last year's comparable three month period of $ 330,140. This was due
primarily to an increase in salaries and office personnel.

Liquidity and Capital Resources

         As of March 31, 1999, the Company had working capital of ($343,475) and
a current ratio of 0.66 to 1. This represents a decrease in working capital
since December 31, 1998 of $358,887.

         The Company intends to fund its future operations, pursue research and
development of current and future products and expand operations through product
rental and sales.

Impact of Inflation

         Although the Company has not attempted to calculate the effect of
inflation, management does not believe inflation has had a material effect on
its results of operations. Material increases in costs and expenses in the
future could have a significant impact on the Company's operating results to the
extent that the effect of such increases cannot be transferred to its customers.

Impact of Year 2000 Issue

         The Company is in the process of assessing its computer applications to
insure their functionality with respect to the "Year 2000" millennium change. At
present, the Company does not anticipate that material incremental costs will be
incurred in any single future year due to the year 2000 issue.

Forward-Looking Information

         The Private Securities Litigation Reform Act of 1995 provides a "safe
harbor" for certain forward-looking statements made by the Company in its
disclosures to the public. There is certain information contained herein in the
Company's press releases and in oral statements made by authorized officers of
the Company which are forward-looking statements, as defined by such Act. When
used herein, in the Company's press releases and in such oral statements, the
words "estimate," "project", "anticipate", "expect", "intend", "believe",
"plans", and similar expressions are intended to identify forward-looking
statements. Because such forward-looking statements involve risks and
uncertainties, there are important factors that could cause actual results to
differ materially from those expressed or implied by such forward-looking
statements

                           PART II - OTHER INFORMATION
               For the Three Months Ended March 31, 1999 and 1998

Item 1.  Legal Proceedings

The Company is involved as plaintiff in litigation filed in August 1994,
alleging deceptive acts and practices, false advertising, unfair competition,
breach of fiduciary duty under New York law and under Federal Law. The complaint
demands damages in an unspecified amount for compensatory, punitive and treble
damages, profits and attorneys' fees. The defendants answered in April 1997 and
asserted counterclaims against the Company for alleged Federal Law violations,
interference with contract, deceptive acts and unfair trade practices and trade
disparagement. The counterclaims demand unspecified damages.

It is impossible for counsel at this time to assess the defendants'
counterclaims. Management for the Company believes that the defendants at this
time may not have significant assets and that all of the counterclaims are
without merit.

The Company was initially involved as a defendant in litigation, commenced on
June 19, 1997, with a former employee. The complaint alleges that the Company
entered into a salary-loan agreement in the amount of $94,064 with the employee
and that said amount was not paid. The Company is vigorously defending the
lawsuit on the grounds that (1) the amount was only to be paid when the Company
had sufficient funds to make the payments and (2) the action is barred by the
applicable statute of limitations. The Company also interposed a counterclaim
for the misuse of corporate funds. The parties are currently conducting
discovery; an evaluation of the likely outcome cannot be made at this early
stage of litigation. The liability for the amount in question is reflected on
the 1998 and 1997 financial statements.

On September 10, 1997 and on October 28, 1997 the Health Care Financing
Administration of the United States Department of Health & Human Services
Departmental Appeals Board ("the Appeals Board") notified the Company that the
Medicare Appeals Council ("the Council") had decided to review certain decisions
made earlier in 1997 wherein an ALJ had concluded that the Company's diapulse
equipment was durable medical equipment and that the related treatment to the
beneficiary was medically necessary, and therefore, the Company was entitled to
be paid. The Company was notified that the Council is reviewing these decisions
because it believes that the ALJ's decisions are not supported by substantial
evidence, and because there is a broad policy issue in these cases that may
affect the public interest. With respect to the September 10, 1997 notification,
the Council vacated the


                                      -11-

ALJ's decision and remanded the cases back to an ALJ for further proceedings
including a new decision. In view of (1) the foregoing and (2) the lack of
significant collections and age of the receivables, the Company has provided an
allowance for doubtful receivables of approximately $1,493,000, the remaining
uncollected balance as of December 31, 1998. For the year ended December 31,
1997 the Company provided an allowance of approximately $1,007,000, the
remaining uncollected balance of the Medicare Accounts Receivable as of October
12, 1998. In connection with the above, the Company (1) provided an allowance
for doubtful accounts of $11,306 and $37,949 for commission advances for the
years 1998 and 1997, respectively, and (2) reversed accrued commissions payable
of $99,681 and $58,197 for the years 1998 and 1997, respectively.
