Item 1. Description of Registrant's Securities to be Registered.

As of August 11, 2006, the Registrant's authorized Common Stock consisted of
20,000,000 shares, of which, 13,519,481 shares were outstanding.

Holders of Common Stock are entitled to one vote for each share held of record
on all matters to be voted on by stockholders. There are no preemptive or
conversion rights or other subscription rights and there are no redemption or
sinking fund provisions applicable to the Common Stock.

Subject to the rights of any preferred stock which may be outstanding at the
time, holders of Common Stock have equal rights, share for share, to receive
dividends when, as and if declared by the Board of Directors. The current policy
of the Registrant's Board of Directors is to retain all future earnings of the
Registrant, if any, and not to pay cash dividends which, under the Delaware
General Corporation Law (the "DGCL"), can only be paid from earnings. The
payment of future dividends, if any, will be at the discretion of the Board of
Directors and will depend upon many factors, including the Registrant's
earnings, financial position, capital requirements and other factors. Therefore,
there can be no assurance as to future dividends.

The Common Stock is currently listed on the American Stock Exchange under the
symbol "MED."
