Schedule 13D/A

CUSIP No. 46426P103  Page 7 of 9 Pages

The undersigned, Alexander Finance, L.P. ("Alexander")
hereby amends its Schedule 13D as filed on November 12,
1999 and as previously amended (the "Schedule 13D")
relating to the Common Stock of ISCO International, Inc.
Unless otherwise indicated, all capitalized terms used
herein but not defined herein shall have the same meaning
as set forth in the Schedule 13D.  Except as set forth
herein, the Schedule 13D, as previously amended, remains
unchanged.

Item 3. Source and Amount of Funds

The Common Stock beneficially owned by Alexander and Grace
was purchased with working capital and partnership funds.

Item 4. Purpose of Transaction

The Company provided the following information in a form
8-K filed on May 20, 2009:

   As previously reported by ISCO International, Inc. (the
   "Company"), as of April 30, 2009, the Company had
   approimately $25.2 million in outstanding indebtedness
   due and owning to its lenders, Alexander Finance, L.P.
   and Manchester Securities Corporation (together, the
   "Lenders").  On May 1, 2009, the Lenders delivered a
   notice of default to the Company, in which the Lenders
   declared the entire outstanding amount of indebtedness
   immediately due and payable.  Pursuant to the terms of
   the loan documents, the indebtedness was secured by a
   lien on all of the Company's assets.  On May 19, 2009,
   the Lenders conducted a public foreclosure sale pursuant
   to Article 9 of the New York Uniform Commercial Code
   (the "Asset Sale").  At the Asset Sale, ISCO
   International, LLC (the "Buyer") purchased substantially
   all of the assets (the "Purchased Assets") of the
   company by issuing a successful credit bid of $10
   million consisting of secured obligations of the Company
   which the Buyer previously obtained from the Lenders.
   The Buyer is owned by the Company's Lenders.

In connection with the $10 million successful credit bid
described above, Alexander credit bid the following debt of
the Company, which totaled $5,300,000 principal amount
(In addition, Manchester Securities Corporation credit bid
$4,700,000 of their debt as part of this transaction):
a. $975,000 in principal of 9.5% Secured Grid Notes due
8/1/2010
b. $1,650,000 in principal of 9.5% Secured Convertible
Notes due 8/1/2010
c. $1,500,000 in principal of 7.0% Senior Secured
Convertible Notes due 8/1/2009
d. $1,175,000 in principal of 7.0% Senior Secured
Convertible Notes due 8/1/2009

As a result, the Company's current debt held by Alexander
is as follows:
a. $4,172,874.96 in principal of 7.0% Senior Secured
Convertible Notes due 8/1/2009
b. $2,500,000 in principal of 5% Senior Convertible Notes
due 6/22/2010

This current principal amount of debt, $6,672,874.96, along
with accrued and unpaid interest associated with debt of
the Company held by Alexander, amounting to $1,440,745.80,
is currently convertible into 34,405,010 shares of the
Company's common stock.


Item 5. Interest in Securities of the Issuer

(a) As of the date of this Amendment, Alexander, if it
converted its 5% convertible notes, 7% convertible
notes and accrued interest on the various convertible
notes, would beneficially own 71,469,856 shares of Common
Stock, representing approximately 27.2% of the outstanding
shares of Common Stock.  Grace beneficially owns 11,000,000
shares of Common Stock, representing approximately 4.2% of
the outstanding shares of Common Stock.  As general partner
of Grace and Alexander, Spurgeon may be deemed beneficial
owner of 82,469,856 shares of Common Stock, or 31.4% of the
outstanding shares of Common Stock, although they otherwise
disclaim beneficial ownership. As general partner of
Alexander, Bun may be deemed beneficial owner of 71,469,856
