ITEM 2 - PURCHASE OF STOCK FROM J.C. LANDON

On June 1, 1988 the Company and Dr. Landon agreed to consolidate the previous
loan facilities available to Dr. Landon from the Company into a single loan of
$100,000. The consolidated loan had a five year term with repayment of
principal deferred for three years. The loan bears interest at the six month
certificate of deposit rate paid by Signet Bank, Maryland and the rate is
adjusted quarterly. On September 29, 1989 the Company agreed to increase the
loan to $125,000. On September 21, 1990, the Company agreed to increase the
loan to $150,000. Pursuant to Dr. Landon's current employment agreement, the
loan is to be repaid in five installments of $30,000 plus interest within six
weeks after the end of each of the next five fiscal years beginning with fiscal
year 1992.

The largest amount owed by Dr. Landon during the fiscal year ended May 31, 1995
in respect to his loan facilities was $90,000, excluding interest accrued
amounting to $4,455. There was no addition to the loan during this fiscal
year. On July 1, 1994, Dr. Landon made a payment of $2,745 on accrued
interest. On June 6, 1994, the Company agreed to defer Dr. Landon's third
$30,000 repayment and make the payment due as two $15,000 installments paid
with the fourth and fifth $30,000 repayments respectively. On May 31, 1995, in
recognition of Dr. Landon's service to the Company and in order to promote Dr.
Landon's continued employment with the Company, the Board of Directors agreed
in principle to purchase common stock of the Company held by Dr. Landon at
market value in an amount sufficient to fund the payment of the $45,000
installment payment plus accrued interest due after fiscal year 1995 and in a
similar manner to purchase common stock of the Company held by Dr. Landon at
market value in an amount sufficient to fund the payment of the final $45,000
installment payment plus accrued interest due after fiscal year 1996. The 1996
payment would be made at the time the loan payment is due.

The Board's resolution was approved (3-0, J.C. Landon abstaining).

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR APPROVAL OF PURCHASE OF DIAGNON
SHARES FROM DR. LANDON TO RETIRE DR. LANDON'S COMPANY LOAN. PROXIES SOLICITED
BY THE BOARD WILL BE SO VOTED UNLESS SHAREHOLDERS SPECIFY A CONTRARY CHOICE ON
THE PROXY CARD.

ITEM 3 - RATIFICATION OF INDEPENDENT PUBLIC ACCOUNTANTS

The Board of Directors recommends the ratification of the firm of Deloitte &
Touche LLP as independent public accountants for fiscal year 1996. As in prior
years, representatives of Deloitte & Touche LLP will be present at the Annual
Meeting with the opportunity to make a statement if they desire to do so and
will be available to respond to appropriate questions raised at the meeting.

Deloitte & Touche LLP has audited the financial statements of Diagnon since
1982. Services provided in connection with the audit function by Deloitte &
Touche LLP for the fiscal year 1995 included primarily the examination of
Diagnon consolidated financial statements, and the review of filings with the
Securities and Exchange Commission.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE ELECTION OF DELOITTE & TOUCHE
LLP AS INDEPENDENT PUBLIC ACCOUNTANTS FOR THE FISCAL YEAR 1996. PROXIES
SOLICITED BY THE BOARD WILL BE SO VOTED UNLESS SHAREHOLDERS SPECIFY A CONTRARY
