Securities covered under the Registration Statement filed under (i) remain
unsold during the effective period of such Registration Statement, then within
20 days following receipt of a written notice from the holders representing a
majority of such unsold Registrable Securities, another Registration Statement
so as to permit a resale of the Securities under the Securities Act by the
Holders as selling stockholders and not as underwriters."

LOAN AGREEMENT

 

Second Amendment

(this “Second Amendment”) dated as of February 20, 2003 between MEDIS

WHEREAS, the

Borrower and the Bank are parties to a Loan Agreement dated as of December 29,

2000 (the “Agreement”); and

 

WHEREAS, the

Borrower and the Bank entered into the First Amendment to the Agreement, dated

as of October 24, 2002 and effective as of September 30, 2002, amending the

definition of Termination Date to read December 26, 2003; and

 

WHEREAS, the

Borrower has requested that the Bank amend, and the Bank has agreed to amend

certain provisions of the Agreement.

 

NOW, THEREFORE,

the parties hereto hereby agree as follows:

 

1.             All capitalized terms used herein, unless otherwise

defined herein, have the same meanings provided therefor in the Agreement.

 

2.             The definition of Termination Date as defined in Section

1.1 (Defined Terms) of the Agreement is hereby amended in its entirety to read

as follows:

 

“Termination Date”

shall mean July 1, 2004 or, if such date is not a Business Day, the Business

Day next succeeding such date.

 

3.             The Borrower hereby represents and warrants to the Bank

that:

 

(a)           Each and every of the representations

and warranties set forth in the Agreement and/or the documents executed

pursuant thereto or in connection therewith is true as of the date hereof and

with the same effect as though made on the date hereof, and is hereby

incorporated herein in full by reference as if fully restated herein in its

entirety.

 

(b)           No Default or Event of Default and no

event or condition which, with the giving of notice or lapse of time or both,

would constitute such a Default or Event of Default, now exists or would exist.

 

4.             All obligations in connection with the Agreement are and

shall continue to be (i) secured by the collateral referenced in the

Agreement and more fully described in one or more pledge agreements in favor of

documents referred to therein.  Whenever
