Re: Amendment to Section 4.2 of the June 30, 1998 Development
---------------------------------------------------------
Agreement
---------
Ladies and Gentlemen:
Xxxxxx Healthcare Corporation, a Delaware corporation ("Baxter") is a party to
that certain Development, Manufacturing and Marketing Agreement with Cerus
Corporation, a Delaware corporation ("Cerus"), originally dated April 1, 1996,
as amended and restated June 30, 1998 (the "Agreement"). Section 4.2 of the
Agreement sets forth certain "standstill" obligations on the part of Baxter and
its "Affiliates" (as that term is defined in Section 2, sub-heading "Baxter"),
as to Cerus equity securities.
Baxter hereby agrees, covenants and consents that all references in Section 4.2
of the Agreement to "twenty and one-tenth percent" or "20.1%" shall, as of the
date of this letter, be amended to read "five and four-tenths percent", or
"5.4%" respectively.
No other term of the Agreement shall be deemed amended hereby.
It is understood that our consent to these changes effectively renders any Cerus
equity securities acquired by Baxter in excess of this newly lowered 5.4%
threshold "Prohibited Securities" as that term is defined in the Agreement.
Sincerely,
Xxxxxxx X. Xxxxxxxx
Senior Vice President
