             REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Plan Administrator and Participants
Cambrex Corporation Savings Plan

We have audited the accompanying statement of net assets available for benefits
of Cambrex Corporation Savings Plan as of December 31, 2005, and the related
statement of changes in net assets available for benefits for the year then
ended. These financial statements are the responsibility of the Plan's
management. Our responsibility is to express an opinion on these financial
statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audit provides a
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the net assets available for benefits of Cambrex
Corporation Savings Plan as of December 31, 2005, and the changes in its net
assets available for benefits for the year then ended, in conformity with
accounting principles generally accepted in the United States of America.

Our audit was performed for the purpose of forming an opinion on the 2005 basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes is presented for the purpose of additional analysis and
is not a required part of the 2005 basic financial statements but is
supplementary information required by the Department of Labor's Rules and
Regulations for Reporting and Disclosure under the Employee Retirement Income
Security Act of 1974. This supplemental schedule is the responsibility of the
Plan's management. The supplemental schedule has been subjected to the auditing
procedures applied in the audit of the 2005 basic financial statements and, in
our opinion, is fairly stated in all material respects in relation to the 2005
basic financial statements taken as a whole.

CAMBREX CORPORATION SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

1.   DESCRIPTION OF PLAN

     The following brief description of the Cambrex Corporation Savings Plan
     (the "Plan") is provided for general information purposes only.
     Participants should refer to the Plan document for a more complete
     description of the Plan's provisions.

     GENERAL

     The Plan is a defined contribution plan to provide all eligible employees
     of Cambrex Corporation ("Cambrex" or the "Company") and its subsidiaries a
     vehicle to accumulate savings. The Plan is subject to the provisions of the
     Employee Retirement Income Security Act of 1974 ("ERISA"). The Plan was
     designed to enhance the existing retirement program for employees of the
     Company. The assets of the Plan are maintained, and transactions therein
     are executed, by Fidelity Management Trust Company ("Fidelity" or the
     "Trustee"). Fidelity also serves as recordkeeper and custodian of the Plan.

     ELIGIBILITY FOR PARTICIPATION

     Each employee who was a participant in a previous plan shall continue as a
     participant under the provisions of the Plan as of the Effective Date, as
     defined by the Plan document. All other employees, except those covered
     under a collective bargaining agreement who must bargain for the benefit,
     who work at least 20 hours per week or 1,000 hours per year, are eligible
     to participate in the Plan on the first of the month following completion
     of thirty consecutive days of service.

     PARTICIPANT ACCOUNTS

     Each participant's account is credited with the participant's contribution
     and allocations of (a) the Company's contribution and (b) Plan earnings,
     and charged with an allocation of administrative expenses. Allocations are
     based on participant earnings or account balances, as defined. The benefit
     to which a participant is entitled is the benefit that can be provided from
     the participant's vested account.

     CONTRIBUTIONS

     Participants may elect to make, through payroll deduction, contributions in
     whole percentages of at least 1%, and not more than 50%, of their
     compensation on a before-tax or after-tax basis. Pre-tax participant
     contributions may not exceed the smaller of 50% of the participant's base
     compensation or $14,000 in 2005. Participants who have attained age 50
     before the end of the Plan year are eligible to make catch-up
     contributions. The catch-up contribution itself is limited to $4,000 in
     2005 and will increase to $5,000 in 2006. Participants may also contribute
     eligible amounts representing distributions from other qualified defined
     benefit or defined contribution plans or certain individual retirement
     accounts.

     The Company matches 100% of employees' contributions based on the first 3%
     of their compensation; an additional 50% of the contribution based on the
     succeeding 3%; and no match with respect to contributions in excess of 6%.
     All Company matching is made in the form of Company common stock, which
     participants can self-direct in this fund at anytime after the employer
     contribution is made.

     VESTING

     A participant's contributions plus corresponding actual earnings shall
     always be fully and immediately vested. Participants shall vest in the
     matching employer contributions at twenty percent (20%) for each year of
     service completed. If not already fully vested under the preceding basis,
     participants shall be 100% vested in their matching employer contributions
     upon normal


                                       6



CAMBREX CORPORATION SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS - (CONTINUED)

     retirement date, permanent disability, or death. At the time of
     termination, any unvested employer contributions are applied to a
     forfeiture account within the Plan. These forfeited Company contributions
     are accumulated in the forfeiture account and are available to reduce
     subsequent Company contributions. Forfeitures for 2005 and 2004 were
     $180,086 and $135,607, respectively. Cumulative unused balances in the
     forfeiture account amounted to $23,430 and $147,448 at December 31, 2005
     and 2004, respectively. Also, in 2005, employer contributions were reduced
     by $247,223 from forfeited nonvested accounts.

     PAYMENT OF BENEFITS

     On termination of service due to death, disability, or retirement, a
     participant may elect to receive a lump-sum amount equal to the value of
     the participant's vested interest in his or her account. For termination of
     service for other reasons, a participant may receive the value of the
     vested interest in his or her account as a lump-sum distribution. Effective
     March 28, 2005, all vested amounts less than $1,000 will be immediately
     distributed.

     LOANS TO PARTICIPANTS

     Participants may borrow from their accounts a minimum of $1,000 up to a
     maximum equal to the lesser of 50% of their vested account balance or
     $50,000, subtracting the participants' highest outstanding loan balances
     over the previous twelve months. Only one outstanding loan is allowed at
     any given time, and no more than one loan will be approved for any
     participant in any twelve-month period. There are two types of loans
     available: a regular loan, with a repayment period from one year up to five
     years; and a primary residence loan, with a repayment period from one year
     up to 15 years. Loans are collateralized by the balance in the
     participant's account and bear interest at 0.5% above the prime rate
     determined each October 1, or the first business day thereafter. The
     amounts borrowed are transferred from the investment funds to the
     participant loan fund on a proportional basis. On a monthly basis,
     repayments of principal and interest are transferred to the investment
     funds. The loans are secured by the balance in the participant's account
     and bear interest at rates which are commensurate with local prevailing
     rates. In 2005, interest rates ranged from 4.5 percent to 10 percent.
     Principal and interest is paid ratably through payroll deductions.

2.   SIGNIFICANT ACCOUNTING POLICIES

     BASIS OF ACCOUNTING

     The financial statements of the Plan have been prepared on the accrual
     basis of accounting.

     PLAN EXPENSES

     All costs of administering the Plan are paid by the participants to the
     extent not paid by the Company.

     PAYMENT OF BENEFITS

     Benefits are recorded when paid.

     USE OF ESTIMATES

     The preparation of financial statements in conformity with accounting
     principles generally accepted in the United States of America requires
     management to make significant estimates and assumptions that affect the
     reported amounts of net assets available for benefits and disclosures of
     contingent assets and liabilities at the date of the financial statements.
     Actual results could differ from those estimates.

CAMBREX CORPORATION SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS - (CONTINUED)

     RISKS AND UNCERTAINTIES

     The Plan provides for various investment options in funds that can invest
     in a combination of stocks, bonds, fixed income securities, mutual funds,
     and other investment securities. Investment securities are exposed to
     various risks, such as interest rate, market and credit. Due to the level
     of risk associated with certain investment securities and the level of
     uncertainty related to changes in the value of investment securities, it is
     at least reasonably possible that changes in risks in the near term would
     materially affect participants' account balances and the amounts reported
     in the Statements of Net Assets Available for Benefits and the Statement of
     Changes in Net Assets Available for Benefits.

     INVESTMENT VALUATION AND INCOME RECOGNITION

     The Plan's investments are stated at fair value. Cambrex common stock is
     traded on a national securities exchange and is valued at the last reported
     sales price of the day. Mutual funds are valued based on the published
     market value as quoted on a national securities exchange. Securities traded
     on the over-the-counter market are valued at the last reported bid price.
     Purchase and sale of securities are reflected on a trade date basis with
     the gain or loss recognized on the sale of securities being based on the
     average cost. Dividend income is recorded on the ex-dividend date. Interest
     income is recorded as earned on an accrual basis. Participant loans are
     valued at their outstanding balance, which approximates fair value.

3.   INVESTMENTS IN EXCESS OF 5% OF NET ASSETS

     The following presents investments that represent 5% or more of the Plan's
     net assets as of December 31, 2005 and 2004:



                                                  2005          2004

Spartan US Equity Index                         7,217,892     6,812,756


     During 2005, the Plan's investments (including gains and losses on
     investments bought and sold, as well as held during the year) depreciated
     in value by $6,521,871 as follows:


                  
Cambrex Stock Fund   $(5,950,829)
Mutual Funds            (571,042)

   Total             $(6,521,871)
                     ===========


     Calculations of the portion of the total funds to be allocated to the Plan
     have been made by the Trustee. The assets held by each fund are described
     in the prospectus of the fund, which are available to the Plan
     participants. Each fund offers different investment opportunities from
     assets consisting of cash and short-term investments, corporate bonds,
     common stocks, preferred stocks and government securities. Each fund has an
     investment manager who exercises discretionary authority concerning
     investment vehicles within the fund.

4.   RELATED PARTY TRANSACTIONS

     The Cambrex Stock Fund invests primarily in Cambrex common stock and
     maintains approximately 3%-4% of its assets in cash and temporary liquid
     investments. Employee contributions and the employer match are used to buy
     units in the fund. Shares of Cambrex common stock are purchased by the
     Trustee on the open market or in stock issued by Cambrex at the average of
     the high and low trading price on the day of contribution. All other
     transactions of Cambrex common shares were traded on the New York Stock
     Exchange ("NYSE"). Employee and employer contributions, dividends, and
     appreciation thereon can be transferred out of the Cambrex Stock Fund or
     transferred to another investment fund without restriction. These Plan
     transactions are permitted under the Plan provisions and are specifically
     exempt from any ERISA "Party in Interest" regulations. Each participant can
     exercise voting rights attributable to the shares allocated to their
     account. Fidelity serves as Trustee, recordkeeper, and custodian of the
     Plan and, therefore, is a party-in-interest. Fees paid by the Plan for the
     investment management services amount to $62,488 for the year ended
     December 31, 2005.

5.   PLAN TERMINATION

     Although the Company has not expressed any intention to do so, the Company
     has the right under the Plan to temporarily or permanently discontinue its
     employer contributions to the Plan or to terminate or partially terminate
     the Plan at any time subject to the provisions set forth by ERISA.

     In the event of, and upon, the Company's termination or partial termination
     of the Plan or complete discontinuance of contributions, the interest in
     the portion of each participant's account balance attributable to employer
     contributions shall become fully vested. Unless the Company's Board of
     Directors (the "Board") deems otherwise, termination of the Plan shall not
     accelerate any such payments for the benefit of the participants or their
     beneficiaries, but the assets shall continue to be held for distribution
     and application in the manner prescribed by the Plan.

6.   TAX STATUS

     The Internal Revenue Service issued its latest determination letter on
     April 4, 2003, which stated that the Plan and its underlying trust qualify
     under the applicable provisions of the Internal Revenue Code and,
     therefore, are exempt from Federal income taxes. Although the Plan has been
     amended since receiving the determination letter, the Plan administrator
     believes that the Plan is currently designed and being operated in
     compliance with the applicable requirements of the Internal Revenue Code.
