ITEM 8.01  OTHER EVENTS

As reported in the Diomed Holdings, Inc. (the "Company") Current Report on Form
8-K filed on June 2, 2006, the American Stock Exchange ("AMEX") notified the
Company that it failed to satisfy Section 1003(a)(ii) of the AMEX Company
Guide's standards for continued listing on the AMEX. The basis for this failure
is that the Company's stockholders' equity, as reported in the Company's
Quarterly Report on 10-QSB for the quarter ended March 31, 2006, is less than
$4,000,000. Application of this standard excludes $7.9 million of
mezzanine-level preferred stock reported on the Company's balance sheet at March
31, 2006.

The AMEX invited the Company to submit to it a plan setting forth the action
that the Company has taken, or will take, that would bring the Company into
compliance with this continued listing standard within 18 months. The Company
timely submitted such a plan to the AMEX.

On August 3, 2006, the AMEX notified the Company that the AMEX has determined
that the Company made a reasonable demonstration of an ability to regain
compliance with the continued listing standards by the end of the plan period
(which is December 1, 2007). Accordingly, the Company expects to continue its
listing on the AMEX and to regain compliance with Section 1103(a)(ii) and to be
in compliance will all other applicable AMEX continued listing criteria.

As a condition to the continued listing during the plan period, the Company will
provide the AMEX with updates regarding the initiatives set forth in the plan
from time-to-time (and at least quarterly), and will be subject to periodic
review by the AMEX. If the Company does not demonstrate to the AMEX that it has
made progress consistent with the plan to regain compliance with the AMEX
continued listing standards by December 1, 2007, or if the AMEX determines that
delisting is appropriate in the public interest, then the AMEX may initiate
delisting proceedings.

The Company's proposed $10 million private placement equity financing, announced
July 27, 2006, is one of the significant milestones set forth in the plan. If
this financing is completed, stockholders' equity will increase to up to $20
million as a result of both the new $10 million to be invested in exchange for a
new series of preferred stock (which will be included in stockholders' equity
for purposes of AMEX Rule 1103(a)(ii)) and the exchange of all currently
outstanding shares of preferred stock (which are not currently included in
stockholders' equity for the purposes of AMEX Rule 1103(a)(ii)) for a shares of
the new series of preferred stock. Therefore, the Company will be in compliance
with AMEX Rule 1103(a)(ii) immediately upon completion of this proposed
financing.

A copy of the Notice is attached hereto as Exhibit 99.1, and a copy of the
Company's press release regarding receipt of the AMEX August 7, 2006 notice is
attached hereto as Exhibit 99.2.
