opinion of management, all adjustments (which included only normal recurring

2002 annual report to shareholders. There have been no changes of significant

                         DIAPULSE CORPORATION OF AMERICA
                           PART II - OTHER INFORMATION
               For the Three Months Ended March 31, 2003 and 2002

Results of Operations

         Net sales and rentals for the current three months increased by
$243,652 to $457,729 from last year's comparable three month period of $214,077.
This was due primarily to machine sales.

         Operating expenses for the current three months increased to $400,053
from last year's comparable three month period of $210,252. This was due mainly
to reserve for bad debts set up in this quarter.

Liquidity and Capital Resources

         As of March 31, 2003 the Company had working capital of $388,393 and a
current ratio of 1.87 to 1. This represents a decrease in working capital since
December 31, 2002 of $7,301.

         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.

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, 2003 and 2002

Item 1.  Legal Proceedings

The Company was 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 against corporate and individual
defendants. In early 2000, a settlement agreement was reached whereby all claims
against the Company were dismissed with prejudice and one of the corporate
defendants agreed to pay the Company the sum of $50,000 with interest rate of 9%
per year, in level monthly installment payments of $1,867.41. The agreement
further provided that in the event of failure to make the installment payments
when due, the entire balance would immediately become due and payable and the
Company would be entitled to enter a judgement for the balance. The agreement
also provides for the defendants to refrain from engaging in certain marketing
practices in the future. The defendants failed to make any payments after the
payment due on January 2001 and in late 2001 a judgment for $39, 215.61 was
entered against the corporate defendant who had agreed to the monetary
settlement. The Company is currently attempting to enforce the judgement but is
not aware of any assets owned by the judgment debtor.

A former employee of the Company, who was terminated in May 1999, filed five
small claim actions against the Company and other employees and an
officer-shareholder of the Company. Each action seeks $3,000 in damages. The
former employee's son also filed one small claim action for approximately $1,500
against the Company and an employee and an officer-shareholder of the Company.
Most of the cases allege various employment contract and/or labor violations;
some allege liability for property allegedly held or used by the Company. All
actions were instituted after the employee was terminated from employment. It is
the opinion of counsel that the actions filed by the former employee and his son
are either without merit or frivolous. The Company is awaiting a decision.

                         DIAPULSE CORPORATION OF AMERICA
                           PART II - OTHER INFORMATION
               For the Three Months Ended March 31, 2003 and 2002

The Company also sued a former employee alleging that this former employee,
without authorization, took trade secrets and other confidential information and
documents relating to the Company. The lawsuit seeks to recover possession of
the items allegedly taken by the former employee and to enjoin the former
employee from distributing, sharing or selling the trade secrets and other
confidential information. The former employee counterclaimed for malicious
prosecution and seeks damages in the sum of $1,000,000. In late 2001 the lawsuit
was settled by a stipulation that was "so ordered" by the court. The stipulation
provides that the defendant be enjoined from utilizing, distributing, sharing,
selling or disseminating the Company's trade secrets which were the subject of
the litigation.

A former independent contractor sued the Company for an amount in excess of
$75,000 pursuant to a signed Commission salesperson Agreement. In January 2003
The Company deposited $75,000 in escrow pending a decision by arbitration on the
Company's claim for loss of revenue on two machines utilized by the independent
contractor. The Company is awaiting a decision.

The Company filed a claim with one of its insurance carriers for loss of, and
damage to, property that was being stored with a storage company. The insurance
carrier was unable to process the claim because the storage company refused to
allow access to inspect the property unless the insurance carrier agreed not to
exercise its right of subrogation. The property remains at the storage company
facility pending final resolution of the claim. In September 2001, the storage
company sued the Company for unpaid storage of approximately $80,000. The
company denies liability on the merits of the case and also has raised the
statute of limitations as a partial defense. The Company counter sued the
storage company for $80,000 for damages done to their machines. Counsel ventures
no opinion on the ultimate outcome, but believes there are good defenses
although some liability is possible.
