Item 8      Other Events

     Cambrex Corporation (the "Company") is reporting that on April 4, 2006, the
Company and certain of its subsidiaries received a summons and complaint
("Complaint") from the Buyer of the Rutherford Chemicals Business ("Buyer"),
which was filed in the Supreme Court of the State of New York, County of New
York. The Complaint seeks indemnification, declaratory and injunctive relief. As
disclosed in the Company's Quarterly Report on Form 10-Q for the quarterly
period ending September 30, 2005, Buyer is seeking indemnity pursuant to the
October 2003 Purchase Agreement for alleged (i) for alleged breaches of
representations, warranties and covenants covering each of the five operating
sites sold to Buyer related to facility structures, utilities and equipment and
an allegedly related breach by Buyer of a Customer Supply Agreement arising from
a breach of equipment warranty at the Harriman facility (collectively "Equipment
Matters"); and (ii) claims related to several environmental matters at each of
the five operating locations, most of which relate to the former Harriman
location (collectively "Environmental Matters"). The Complaint includes all of
the claims for indemnity and damages related to Equipment Matters and
Environmental Matters as disclosed in the Company's Quarterly Report on Form
10-Q as well as additional environmental claims.

     The Company continues its evaluation of Purchaser's allegations and intends
to defend itself against these claims vigorously. As such the Company has
recorded no reserves for this matter. The Company believes that the Equipment
Matters are without merit. Concerning the Environmental Matters, the Company
believes that based on current information the majority of the claims are either
Buyer's responsibility or without merit and the remaining are otherwise not
reasonably estimable at this time.


The information contained in this Current Report on Form 8-K shall not be deemed
"filed" for purposes of Section 18 of the Securities Exchange Act of 1934 or
otherwise subject to the liabilities of that Section, nor shall it be deemed
incorporated by reference in any registration statement or other document under
the Securities Act of 1933.
