Dear Sirs,

CARGILL FINANCIAL MARKETS PLC AND OTHERS V POLYGON GLOBAL OPPORTUNITIES MASTER
FUND AND OTHERS
------------------------------------------------------------------------------

We refer to the proceedings issued last week by Cargill Financial Markets Plc
and others against Polygon Global Opportunities Master Fund and others.

This letter confirms our view that, as a consequence of these proceedings,
there exists a common interest between our clients (the First to Third
Defendants) and your clients (the Fourth to Ninth Defendants).  In this regard,
to the extent that there are communications between us, they will be cloaked
by common interest privilege.

We should be grateful if you would confirm that this accords with your view.

Yours faithfully



MCDERMOTT WILL & EMERY
