Payment prior to January 28, 2008, Cambrex shall deposit into the Escrow Account

the Note Payment prior to September 30, 2007, the total amount of the Note
Payment due and owing under Section 2.1.2(b) shall be reduced by the amount of
12% interest per annum, calculated per day, from the date of the prepayment

Liabilities suffered or incurred by Cambrex arising out of, resulting from or
relating to (x) the presence of Hazardous Materials at any of the Rutherford
Facilities or (y) Remediation, fines or penalties relating to any Off-Site
release or threatened release of toluene from the toluene plume at the Seal
Sands Facility.

          2.4.2 If Cambrex shall receive notice or otherwise learn of a Third
Party Claim with respect to which Rutherford is obligated to provide
indemnification pursuant to Section 2.4.1 including without limitation any Third
Party Claim brought under any Environmental Laws, Cambrex shall give Rutherford
written notice thereof promptly after becoming aware of such Third Party Claim;
provided, however, that the failure of Cambrex to give notice as provided in
this provision shall not relieve Rutherford of its obligations under Section 2.4
except to the extent that Rutherford is prejudiced by such failure to give
notice. Such notice shall describe the Third Party Claim in reasonable detail
and, if ascertainable, shall indicate the amount (estimated if necessary) of the
Loss that has been or may be sustained by Cambrex.


                                        9

          2.4.3 Rutherford may elect to defend or seek to settle or compromise,
at Rutherford's own expense and by Rutherford's own counsel, any Third Party
Claim. Within thirty (30) days after the receipt of notice from Cambrex in
accordance with Section 2.4.2 (or sooner, if the nature of such Third Party
Claim so requires), Rutherford shall notify Cambrex whether Rutherford will
assume responsibility for defending such Third Party Claim. After notice from
Rutherford to Cambrex of its election to assume the defense of a Third Party
Claim, Rutherford shall not be liable to Cambrex under this Section 2.4 for any
legal or other expenses (except expenses approved in advance by Rutherford )
incurred by Cambrex in connection with the defense thereof; provided that if the
defendants in any such claim include both Rutherford and Cambrex and, in
Cambrex's reasonable judgment, a conflict of interest between Rutherford and
Cambrex exists in respect of such claim, Cambrex shall have the right to employ
separate counsel to represent itself at its own expense. If Rutherford elects
not to assume responsibility for defending a Third Party Claim, or fails to
notify Cambrex of its election as provided in this Section 2.4.3, Cambrex may
defend or (subject to the remainder of this Section 2.4) seek to compromise or
settle such Third Party Claim and seek redress from Rutherford under the terms
of this Agreement.

          2.4.4 If Rutherford chooses to defend or to seek to compromise or
settle any Third Party Claim, Cambrex shall make available to Rutherford any
personnel or any books, records or other documents within Cambrex's control or
which it otherwise has the ability to make available that are necessary or
appropriate for such defense, settlement or compromise, and shall otherwise
cooperate in the defense, settlement or compromise of such Third Party Claim.

          2.4.5 In the event of payment by Rutherford to Cambrex in connection
with any Third Party Claim that Cambrex is not responsible for under the terms
of this Agreement, Rutherford shall, to the fullest extent permitted by
applicable law, be subrogated to and shall stand in the place of Cambrex as to
any events or circumstances in respect of which Cambrex may have any right or
claim relating to such Third Party Claim against any claimant or plaintiff
asserting such Third Party Claim or against any other Person. Cambrex shall
cooperate with Rutherford in a reasonable manner, and at the cost and expense of
Rutherford, in prosecuting any subrogated right or claim.

          2.4.6 Other Procedures for Indemnification. Any claim for
indemnification by Cambrex under Section 2.4 which does not result from a Third
Party Claim shall be asserted by written notice given by Cambrex to Rutherford.
Rutherford shall have a period of twenty (20) days after the receipt of such
notice within which to respond thereto. If Rutherford does not respond within
such twenty (20) day period, Rutherford shall be deemed to have refused to
accept responsibility to make payment. If Rutherford does not respond within
such twenty (20) day period or rejects such claim in whole or in part, Cambrex
shall be free to pursue such remedies as may be available to such party under
this Agreement.

          2.4.7 Indemnification Procedures Apply Equally to Rutherford and
Cambrex.

          In the event Rutherford receives notice of a Third Party Claim
described or covered in Section 2.3.1 (a)(ii) or receives notice of a claim
relating to Off Site Hazardous Materials described or covered in Section
2.3.1(a)(i), Rutherford and Cambrex shall follow and adhere to the provisions of
Section 2.4.2, 2.4.3, 2.4.4, 2.4.5 and 2.4.6, EXCEPT THAT the rights and


                                       10

<PAGE>

obligations set forth for Cambrex in each of these Sections shall apply to
Rutherford and the rights and obligations set forth for Rutherford in each of
these Sections shall apply to Cambrex.

          2.4.8 Notice of Remediation Activities at Nepera.

               (a) Until the earlier of such time as (i) Cambrex receives a "no
further action" letter or its equivalent from the New York State Department of
Environmental Conservation ("NYSDEC") or such other Governmental or Regulatory

RFI corrective action process has been completed as required by applicable law,
Cambrex shall have the right to receive copies of material reports, work plans,
agreements or letters submitted by Rutherford to a Governmental or Regulatory
Authority and other material documents that relate to Remediation at the Nepera
Facility at the same time as such reports, plans, agreements or documents are
submitted to the Governmental or Regulatory Authority, and shall receive prior
notice of and attend any meetings (as an observer) with such Governmental or
Regulatory Authorities; provided that the Parties recognize that ultimate
decision-making authority with respect to such Remediation (other than
Remediation pursuant to the ROD) is retained by Rutherford.

               (b) Until such time as Cambrex receives a "no further action"
letter or its equivalent from NYSDEC or such other Governmental or Regulatory
Authority that Cambrex has completed all required Remediation of Hazardous
Materials at the Nepera Facility pursuant to the ROD, Rutherford shall have the
right to receive copies of any material reports, work plans, agreements or
letters submitted by Cambrex to a Governmental or Regulatory Authority, and
other material documents that relate to Remediation under the ROD at the Nepera
Facility at the same time as such reports, plans, agreements or documents are
submitted to the Governmental or Regulatory Authority, and shall receive prior
notice of and attend any meetings (as an observer) with such Governmental or
Regulatory Authorities; provided that the Parties recognize that ultimate
decision-making authority with respect to such Remediation under the ROD is
retained by Cambrex.

               (c) Rutherford shall not, without first providing reasonable
prior notice to, and obtaining the express written consent of, Cambrex,
communicate with the NYSDEC or any other Governmental or Regulatory Authority or
any third Person regarding Remediation of Hazardous Materials at the Nepera
Facility pursuant to the ROD, and Rutherford shall facilitate the participation
of Cambrex in all such communications. Cambrex shall not, without first
providing reasonable prior notice to, and obtaining the express written consent
of, Rutherford, communicate with the NYSDEC or any other Governmental or
Regulatory Authority or any third Person regarding Remediation of Hazardous
Materials at the Nepera Facility pursuant to the RCRA RFI corrective action
process or Remediation that is otherwise not Cambrex's responsibility under
Section 2.3.1(a)(iv) hereof, and Cambrex shall facilitate the participation of
Rutherford in all such communications.

          2.4.9 Notice of Remediation Activities at CasChem.

               (a) Until such time as Cambrex receives a "no further action"
letter or its equivalent from the New Jersey Department of Environmental
Protection ("NJDEP") or any other Governmental or Regulatory Authority with
jurisdiction over the CasChem Facility that Cambrex has completed all required
Remediation of Hazardous Materials at the CasChem Facility pursuant to ISRA,
Cambrex shall have the right to receive copies of material reports, work plans,
agreements submitted by Rutherford to a Governmental or Regulatory Authority,
and other material documents that relate to Remediation at the CasChem Facility
at the same time as such reports, plans, agreements or documents are submitted
to the Governmental or Regulatory Authority, and shall receive prior notice of
and attend any meetings (as an observer) with such Governmental or Regulatory
Authorities; provided that the Parties recognize that ultimate decision-making
authority with respect to such Remediation (other than Remediation pursuant to
ISRA) is retained by Rutherford.

               (b) Until such time as Cambrex receives a "no further action"
letter or its equivalent from the NJDEP or any other Governmental or Regulatory
Authority with jurisdiction over the CasChem Facility that Cambrex has completed
all required Remediation of Hazardous Materials at the CasChem Facility pursuant
to ISRA, Rutherford shall have the right to receive copies of any material
reports, work plans, agreements submitted by Cambrex to a Governmental or
Regulatory Authority, and other material documents that relate to Remediation at
the CasChem Facility at the same time as such reports, plans, agreements or
documents are submitted to the Governmental or Regulatory Authority, and shall
receive prior notice of and attend any meetings (as an observer) with such
Governmental or Regulatory Authorities; provided that the Parties recognize that
ultimate decision-making authority with respect to such Remediation pursuant to
ISRA is retained by Cambrex.

               (c) Rutherford shall not, without first providing reasonable
prior notice to, and obtaining the express written consent of, Cambrex,
communicate with the NJDEP or any other Governmental or Regulatory Authority or
any third Person regarding Remediation of Hazardous Materials at the CasChem
Facility pursuant to ISRA, and Rutherford shall facilitate the participation of
Cambrex in all such communications. Cambrex shall not, without first providing
reasonable prior notice to, and obtaining the express written consent of,
Rutherford, communicate with the NJDEP or any other Governmental or Regulatory
Authority or any third Person regarding Remediation of Hazardous Materials at
the CasChem Facility that is not Cambrex's responsibility under Section
2.3.1(a)(iii) hereof, and Cambrex shall facilitate the participation of
Rutherford in all such communications.

          2.4.9 Remedies Cumulative. The remedies provided in this Section 2.4
shall be cumulative and shall not preclude the assertion by any Party of any
other rights or the request for any and all other remedies, to the extent
permitted by this Agreement.

     2.5 Sale and Assignability.

          2.5.1 This Agreement shall be binding upon the Parties hereto, their
successors, subsidiaries (except non-wholly owned subsidiaries in China),
assigns, agents, directors, officers and employees, provided that no Party may
assign, delegate or otherwise transfer any of its rights


                                       12

<PAGE>

or obligations under this Agreement or the APA without the consent of the other
Parties hereto. Notwithstanding the foregoing, Rutherford may transfer or assign
in whole or in part its rights and obligations under this Agreement to: (i) one
or more of its subsidiaries or affiliates; (ii) any financial institution
providing purchase money or other financing to Rutherford or to one or more of
its subsidiaries or affiliates; (iii) a purchaser of all or a substantial
portion of the assets of the Rutherford Chemicals Business; or (iv) a purchaser
of all or a substantial portion of the assets of Nepera, but no such transfer or
assignment shall relieve Rutherford of any of its obligations hereunder. In the
case of a sale of all or a substantial portion of the assets of the Rutherford
Chemicals Business, the transferee shall assume the related obligations of
Rutherford hereunder and, in the case of the sale of all or a substantial
portion of the assets of Nepera, only the Person that purchases all or a
substantial portion of the assets of the Nepera Facility directly from
Rutherford (the "Initial Nepera Asset Transferee") shall assume the related
obligations of Rutherford hereunder as they apply to the Nepera Facility. The
Initial Nepera Asset Transferee shall have no obligation to bind future
transferees to the terms of this Agreement; provided, however, that in the event
the Initial Nepera Asset Transferee sells or transfers all or a substantial
portion of the assets of Nepera to a Wholly-Owned Affiliate, such Wholly-Owned
Affiliate shall assume the related obligations of Rutherford hereunder as they
apply to the Nepera Facility. Such obligations shall survive until the earlier
of: (i) thirty (30) months after the Initial Nepera Asset Transfer directly from
Rutherford; or (ii) when all remedial construction required as part of the RCRA
RFI corrective action process is complete or the Nepera Facility receives a
"Completion Notice" from the jurisdictional Governmental or Regulatory
Authorities (such as a "no further action" letter or its equivalent or
acceptance by such Governmental or Regulatory Authority of Rutherford's final
notice of completion). For purposes of this Section 2.5.1, the Initial Nepera
Asset Transferee shall not include any entity that is an Affiliate of
Rutherford. Rutherford hereby represents that it will maintain sufficient assets
to fulfill its obligations under this Agreement in the event of a sale of assets
of the Rutherford Chemicals Business that are material to the overall financial
condition of Rutherford or the sale of a Rutherford Facility by Rutherford.

          2.5.2 If Rutherford enters into any agreement to sell all or a
substantial portion of a Rutherford Facility, Rutherford shall provide Cambrex
with notice of such transaction within 48 hours of closing and shall disclose
all material terms relating to any assumption by the transferee of any of
Rutherford's obligations under this Settlement Agreement.

                                   ARTICLE IV
                    ENFORCEMENT OF THIS AGREEMENT AND THE APA

     4.1 Enforcement of this Agreement and the APA.

          4.1.1 Any claim arising out of or relating to this Agreement, or the
subject matter thereof, including any claim for breach, enforcement,
indemnification or damages under this Agreement, and any future claims arising
out of, relating to, or regarding breach, enforcement, indemnification or
damages under the APA, as amended and modified herein, will be resolved solely
and exclusively through dispute resolution conducted in accordance with the
procedures and rules of the International Institute of Conflict Prevention and
Resolution ("CPR") Rules for Non-Administered Arbitration then in effect; except
that pursuant to Section 13.2 of the CPR Rules for Non-Administered Arbitration,
a Party may seek interim measures and/or provisional relief from a court in
order to protect its rights under this Agreement or the APA. The process for
dispute resolution is prescribed as follows, to the extent such procedures
differ from those set forth in the CPR Rules for Non-Administered Arbitration:

               (a) If, in the opinion of one of the Parties, there is a dispute
between Rutherford and Cambrex with respect to the interpretation or
implementation of this Agreement, the opining Party shall send a written Notice
of Dispute to the other party which outlines the nature of the dispute and
requests informal negotiations to resolve the dispute. Such period of informal
negotiations shall not extend beyond twenty (20) days from the date when the
Notice of Dispute was received unless the period is extended by written
agreement of the Parties. After initiation of the informal negotiation period,
any Party to the dispute may, upon seven (7) days' prior written notice to the
other Party, terminate the informal negotiations.

               (b) If informal negotiations are unsuccessful or are terminated
in accordance with Subparagraph (a), a Party may initiate arbitration by
sending, via certified mail, a written notice of the claim to the other Party
that (i) identifies and describes the nature of each claim asserted, (ii) the
facts upon which each claim is based, and (iii) the relief or remedy sought. The
Party initiating arbitration shall notify CPR that a demand for arbitration has
been made and the Parties shall endeavor to agree on the appointment of a single
arbitrator. If the Parties have not agreed on a mutually satisfactory arbitrator
within fifteen (15) days of the written notice of the claim, the CPR shall
forthwith appoint an arbitrator pursuant to CPR Rule 5.4.

               (c) Within thirty (30) days of receiving a written notice of
claim for arbitration, the responding Party may file an answering statement
setting forth a response to the claim and the issues presented. The filing of
the answering statement shall in no way limit the responding Party's right to
assert other defenses or to assert timely counterclaims or take other positions
that may become apparent during the course of the arbitration.

               (d) The arbitrator will promptly set a hearing date and time,
taking into account the Parties' need to take discovery reasonably necessary for
the prosecution or defense of any claim, and will mail written notice of the
hearing date to each of the Parties at least sixty (60) days in advance, unless
the Parties otherwise agree or mutually waive notice.


                                       15

<PAGE>

               (e) The arbitration shall be held in New York City and the laws
of the State of New York shall apply, without resort to choice of law
principles.

               (f) The arbitrator is empowered to subpoena witnesses and compel
the production of documents to the extent permitted in a judicial proceeding,
upon his or her own initiative or the request of one of the Parties. The
arbitrator may grant injunctions or other relief in such dispute, but may not
award punitive or exemplary damages, unless such limitation is prohibited by
law.

               (g) No later than fifteen (15) days before the arbitration, the
Parties will exchange lists of witnesses, including any experts, and copies of
all exhibits intended to be used at the arbitration. Each party shall have the
right to subpoena witnesses and documents for the arbitration, as well as
documents relevant to the case from third parties.

               (h) The arbitrator shall have the authority to entertain a motion
to dismiss or a motion for summary judgment by any Party and shall apply the
standards governing such motions under the New York CPLR.

               (i) The award of the arbitrator shall be FINAL AND BINDING on the
Parties and may be enforced by any court of competent jurisdiction and may be
executed against the person and assets of the losing Party in any jurisdiction.

          4.1.2 No claim for damages may be made for breach of this Agreement or
for breach of any surviving portion of the APA unless the value of such claim
exceeds $75,000. The arbitrator shall immediately dismiss any claim submitted
for arbitration where the complaining party can not establish that the value of
its claim will exceed $75,000; provided, however, that this provision shall not
apply to a claim or a motion by a Party for interim measures, provisional relief
or injunctive relief as permitted under this Agreement.

     IN WITNESS WHEREOF, the Parties to this Agreement have caused this
Agreement to be duly executed by their respective authorized officers as of the
day and year first written above.

accordance with the schedule of payments set forth in Section 2.1 of the

"Environmental Deposit") shall be made via wire transfer of immediately
available funds to the following account maintained by the Escrow Agent:

                    Bank: Wells Fargo Bank, National Association
                    Location: Indianapolis, Indiana
                    Account Number: TBD
                    ABA Number: 121-000-248
                    Reference: Rutherford Vertellus Environmental Escrow
                    Attention: John D. Alexander

          1.3.2 The Escrow Agent shall invest the Environmental Deposit in an
interest-


                                       19

<PAGE>

bearing account ("Escrow Account") by no later than the close of business on the
business day next following the day on which the Environmental Deposit is
received. In the absence of other written investment instructions, the
Environmental Deposit shall be invested in a Wells Fargo Bank Money Market
Deposit Account (the "MMDA"). The Parties understand that amounts on deposit in
the MMDA are insured, subject to the applicable rules and regulations of the
Federal Deposit Insurance Corporation (FDIC), in the basic FDIC insurance amount
of $100,000 per depositor, per insured bank. This includes principal and accrued
interest up to a total of $100,000. The Parties understand that deposits in the
MMDA are not secured. All reasonable administrative costs, fees and expenses of
the Escrow Agent related to such account (collectively, "Fees") may be deducted
by the Escrow Agent from the Escrow Account.

          1.3.3 All Permitted Investments shall be considered part of the Escrow
Account. In determining whether and how much of the Escrow Account to deposit or
hold in Permitted Investments, the Escrow Agent shall ensure that there are
sufficient funds available to pay Qualified Expenses within the time periods set
forth in 1.4.5 of this Escrow Agreement.

     1.4 Distribution of the Escrow Account.

          1.4.1 Qualified Expenses. For purposes of this Environmental Escrow
Agreement, "Qualified Expenses" means costs incurred on or after July 1, 2007 by
Rutherford or any of its successors, assigns, contractors, agents, employees or
representatives relating to or in connection with Remediation at the five
Rutherford Facilities as follows: any and all Remediation at the Nepera facility
and the Heico Facility; any or all Remediation of toluene at the Seal Sands
Facility; and/or any and all Remediation of mercury at the Zeeland Facility or
any Hazardous Materials at any of the seven closed and inactive lagoons at the
Zeeland Facility and the closed Ketone Sludge Pond at the Zeeland Facility
formerly used to store a variety of chemicals between the 1950s and the 1970s.
Qualified Expenses shall include, without limitation, all costs and expenses
related to the management of the work by Rutherford, attorneys' fees for legal
services rendered in connection with Remediation as described herein, and costs
and expenses related to community relations and outreach to the community to the
extent such costs and expenses relate to Remediation as described herein;
provided that any such Remediation Work has been performed in accordance with
the standards set forth in Section 1.4.3 of this Environmental Escrow Agreement;
provided further that not more than one million dollars ($1,000,000) may be used
for the purpose of paying Rutherford or its designated Representatives for
Qualified Expenses relating to Remediation at the Zeeland, Seal Sands or Heico
Facilities combined and provided further that any costs incurred by Rutherford
with respect to the Remediation Work shall not be considered "Qualified
Expenses" for the purposes of this Environmental Escrow Agreement if such costs
relate to actions taken following the issuance of a "no further action" letter,
certificate of completion, or equivalent notice from a Governmental or
Regulatory Authority issued on or after the date of the execution of this
Agreement, reflecting that the respective Remediation Work to which the incurred
costs related has been completed.

          1.4.2 Cessation or Modification of Remediation Work. Rutherford shall
deliver to Cambrex and the Escrow Agent (a) any order of, or agreement with, any
Governmental or Regulatory Authority in respect of which Rutherford might make a
claim for a distribution hereunder, as well as any modifications or amendments
of or supplements to existing


                                       20

<PAGE>

orders or agreements, as promptly as practicable following the issuance or
execution thereof and (b) any "no further action" letter, certificate of
completion or equivalent document issued with respect to any aspect of, or all,
the Remediation Work as promptly as practicable following the issuance thereof.

          1.4.3 Remediation Work Standards. In order for an expense to be deemed
a Qualified Expense, such expense shall be incurred in connection with
Remediation Work which (a) is conducted in accordance with applicable
Environmental Laws and (b) unless required by a Governmental or Regulatory
Authority, is (i) technically feasible and practicable and (ii) based on
customary and accepted engineering practices.

          1.4.4 Claims by Rutherford. From time to time during the term of this
Environmental Escrow Agreement, Rutherford or any of its successors, assigns,
contractors, agents, employees or representatives (collectively
"Representatives") authorized by Rutherford to act on its behalf may submit to
the Escrow Agent, with copy to Cambrex, a certificate substantially in the form
of Exhibit B (a "Certificate of Instruction"), setting forth the amount of
expenses incurred by Rutherford or its Representatives (the "Owed Amount") which
Rutherford or its Representatives believes to be Qualified Expenses. Each such
Certificate of Instruction shall describe such expenses in reasonable detail and
be accompanied by receipts, invoices and other appropriate and customary
documentation sufficient to demonstrate the amount of such expenses and to
support Rutherford's claim that such expenses are Qualified Expenses.

          1.4.5 Objections and Payment. Cambrex shall have fifteen (15) calendar
days from the date it receives the Certificate of Instruction to provide the
Escrow Agent and Rutherford with written notice objecting to such Certificate or
any portion thereof ("Objection Period"). If the Escrow Agent has not received
from Cambrex a certificate in substantially the form of Exhibit C attached
hereto (an "Objection Certificate") within the Objection Period, the Escrow
Agent shall deliver to Rutherford within seven (7) calendar days following the
expiration of the Objection Period the portion of the Escrow Account equal to
the dollar amount of the Qualified Expenses set forth in the Certificate of
Instruction, up to an aggregate amount equal to the Escrow Account (less any
fees). If the Escrow Agent and Rutherford each receive an Objection Certificate
from Cambrex objecting to the Certificate of Instruction or any portion thereof,
the Escrow Agent shall (i) deliver to Rutherford within such seven calendar day
period the amount of Qualified Expenses that is not in dispute and (ii) retain
the amount disputed pending resolution of the dispute as follows:

               (a) Rutherford and Cambrex shall use their commercially
reasonable efforts to resolve Cambrex's objection by mutual agreement, in which
case Rutherford and Cambrex shall provide the Escrow Agent with a certificate
substantially in the form of Exhibit D attached hereto (a "Resolution
Certificate") stating that Rutherford and Cambrex have agreed that the Owed
Amount referred to in such Certificate of Instruction (or a specified portion
thereof) is payable to Rutherford, so long as sufficient funds are on deposit in
the Escrow Account to make such payment.

               (b) If Rutherford and Cambrex cannot mutually resolve Cambrex's
objection within thirty (30) days after the expiration of the Objection Period,
then Cambrex shall submit the dispute to the Special Master, who shall make a
determination within thirty (30) days


                                       21

<PAGE>

as to whether the Owed Amount, or any portion thereof, constitutes a Qualified
Expense. The Special Master shall base any such determination on whether the
expenses constituting the Owed Amount are costs relating to or associated with a
Qualified Expense as defined in Section 1.4.1 of this Agreement. The decision of
the Special Master shall be final and binding upon the Parties.

               (c) In the event Cambrex submits or makes any objection under any
provision of this Environmental Escrow Agreement or other challenge to
Rutherford's submission for payment from the Escrow Account or request for
Termination of the Environmental Escrow Agreement under Paragraph 1.6 of this
Agreement, and that objection or challenge is resolved by the Special Master in
Rutherford's favor in whole or in part, Cambrex shall pay to Rutherford, within
ten (10) days after resolution of the matter by the Special Master: (i) all fees
and costs incurred by Rutherford in responding to and addressing that part of
Cambrex's objection or challenge that was resolved in Rutherford's favor,
including but not limited to all consultant's and attorneys' fees and the
reasonable hourly fee for employee time used to address such objection or
challenge; and (ii) all fees and costs of the Special Master associated with
addressing and adjudicating that part of Cambrex's objection or challenge that
was resolved in Rutherford's favor. Failure of Cambrex to make a payment of fees
and costs required under this paragraph shall forfeit and extinguish Cambrex's
right to make future objections or challenges to Rutherford's submission of any
claim for reimbursement from the Escrow Account.

               (d) In the event that Cambrex submits or makes any objection
under any provision of this Environmental Escrow Agreement or other challenge to
Rutherford's submission for payment from the Escrow Account or request for
Termination of the Environmental Escrow Agreement under Paragraph 1.6 of this
Agreement, and that objection or challenge is resolved by the Special Master in
Cambrex's favor in whole or in part, Rutherford shall pay Cambrex, within ten
(10) days after resolution of the matter by the Special Master: (i) all fees and
costs incurred by Cambrex in submitting that part of Cambrex's objection that
was resolved in Cambrex's favor by the Special Master, including but not limited
to all consultant's and attorneys' fees and the reasonable hourly fee for
employee time used to address such objection or challenge; and (ii) all fees and
costs of the Special Master associated with addressing and adjudicating that

     1.6 Termination. This Environmental Escrow Agreement shall terminate upon
the earlier of (a) the distribution of all of the Escrow Account in accordance
with the terms hereof, (b) the date that is ten years from the date of the
execution of this Agreement or (c) such earlier date on which the Escrow Agent
receives a written assurance of concurrence (a "Completion Notice") by the
jurisdictional Governmental or Regulatory Authorities (such as a "no further
action" letter or its equivalent or acceptance by such Governmental or
Regulatory Authority of Rutherford's final notice of completion) that
Remediation at the Nepera Facility required under the RCRA RFI corrective action
process has been completed as required by applicable law or, in


                                       22

<PAGE>

the event monitoring or maintenance of the Nepera Facility is required after
completion of any Remediation, such monitoring and/or maintenance (exclusive of
any pump-and-treat remedy involving groundwater) having been conducted for a
period of at least two years without the imposition of additional remediation
requirements, provided, however, that a Completion Notice will not terminate the
Environmental Escrow Agreement if within twenty (20) days following Cambrex's
receipt of a copy of the Completion Notice, Cambrex provides written notice to
the Escrow Agent, with a copy to Rutherford, of its objection to the Completion
Notice under Section 1.4.2 hereof (the "Completion Objection"); and provided
further that subsequent to the Escrow Agent's receipt of a Completion Objection,
this Environmental Escrow Agreement shall terminate if the Escrow Agent receives
either (x) a joint notice from Rutherford and Cambrex stating that Rutherford
and Cambrex have agreed that this Environmental Escrow Agreement shall be
terminated, or (y) a copy of a final, non-appealable judgment of an arbitrator
stating that the Completion Notice satisfies the requirements of Section 1.4.2
hereof. In the event that this Environmental Escrow Agreement terminates
pursuant to Subsection (b) or (c) of this Section 1.6, the Escrow Agent shall
deliver the amount of the Escrow Account then remaining (less any Fees) to
Rutherford. In any event, upon termination of this Environmental Escrow
Agreement, any remaining balance in the Escrow Account shall be paid to
Rutherford.

               CONCERNING THE ESCROW AGENT AND THE SPECIAL MASTER

     2.1 Concerning the Escrow Agent.

          2.1.1 General. Cambrex and Rutherford acknowledge and agree that the
Escrow Agent (a) shall not be responsible for any of the other agreements
referred to herein but shall be obligated only for the performance of such
duties of the Escrow Agent as are specifically set forth in this Environmental
Escrow Agreement, (b) shall not be obligated to take any legal or other action
hereunder which might in its judgment involve expense or liability unless it
shall have been furnished with indemnity acceptable to it, (c) may rely on and
shall be protected in acting or refraining from acting upon any written notice,
instruction, instrument, statement, request or document furnished to it
hereunder and believed by it to be genuine and to have been signed or presented
by the proper person, and shall have no responsibility for determining the
accuracy thereof, and (d) may, at its sole expense, consult counsel satisfactory
to it and the advice or opinion of such counsel shall be full and complete
authorization and protection in respect of any action taken, suffered or omitted
by it hereunder in good faith and in accordance with the advice or opinion of
such counsel.

          2.1.2 Expenses of Escrow. The Escrow Agent shall be entitled to
compensation for out-of-pocket expenses incurred in performing the duties and
obligations imposed under this Environmental Escrow Agreement and an annual fee
in the amount of two-thousand and five hundred dollars ($2,500) for the term of
this Environmental Escrow Agreement. All expenses incurred, and fees paid, shall
be paid from the Environmental Deposit. The Escrow Agent shall not be entitled
to any other fee or compensation.

          2.1.3 Waiver of Liens. Without prejudice to Section 1.6, 2.1.2, and
any other provision of this Environmental Escrow Agreement specifically
providing for the payment of amounts due to the Escrow Agent hereunder, the
Escrow Agent hereby waives and agrees not to

<PAGE>

assert any right of setoff or bank, statutory, equitable or other lien in
respect of the Escrow Account or the distribution thereof.

          2.1.4 Liability of the Escrow Agent. Upon disbursement of all of the
Escrow Account in accordance with the terms hereof, the Escrow Agent shall be
fully and finally released and discharged from any and all duties, obligations
and liabilities hereunder. In the event of a dispute between any of the parties
hereto as to their respective rights and interests hereunder, the Escrow Agent
shall be entitled to hold the Escrow Account then in its possession hereunder
until such dispute shall have been resolved by the parties in dispute and the
Escrow Agent has been notified by instrument jointly signed by all of the
parties in dispute, or until such dispute shall have been finally adjudicated as
provided in Section 3.9. In the event of a dispute, the Escrow Agent may file an
interpleader action and pay the Escrow Account into the registry of the court.
Neither the Escrow Agent nor any of its directors, officers or employees shall
be liable to anyone for any action taken or omitted to be taken by it or any of
its directors, officers or employees hereunder except in the case of any loss,
liability or expense primarily caused by the Escrow Agent's gross negligence,
bad faith or willful misconduct. Cambrex and Rutherford shall, jointly and
severally, indemnify the Escrow Agent and hold it harmless without limitation
from and against any loss, liability or expense of any nature incurred by the
Escrow Agent arising out of or in connection with this Environmental Escrow
Agreement or with the administration of its duties hereunder, including, legal
fees and expenses and other costs and expenses of defending or preparing to
defend against any claim of liability, unless such loss, liability or expense is
primarily caused by the Escrow Agent's gross negligence, bad faith or willful
misconduct. In no event shall the Escrow Agent be liable for indirect, punitive,
special or consequential losses or damages (including without limitation lost
profits), even if advised of the possibility of such losses or damages and
regardless of the form of action.

          2.1.5 Resignation. The Escrow Agent may at any time resign as Escrow
Agent hereunder by providing sixty (60) calendar days' prior written notice of
resignation to the other parties hereto. Prior to the effective date of the
resignation as specified in such notice, Cambrex and Rutherford shall issue to
the Escrow Agent a written instruction authorizing redelivery of the Escrow
Account to a successor escrow agent selected by Cambrex and Rutherford. If no
successor escrow agent is named by Cambrex and Rutherford, the Escrow Agent may
apply to a court of competent jurisdiction for the appointment of a successor
escrow agent. The provisions of 2.1.4 above shall survive the resignation or
removal of the Escrow Agent or the termination of this Environmental Escrow
Agreement.
