request that such Proprietary Materials be supplied as a Custom Product, which
will be supplied at prices to be negotiated in good faith, and taking into
account all concerns under Sections 5.1.3 and 5.2.5.

                  5.1.8 In the event that MPI waives its rights to exclusively
manufacture a specific Licensed Material, CI shall have the right to make or
have made such Licensed Material for use in accordance with Article 2, subject
to the provisions of Sections 3.6, 6.2 and 6.5.

                  5.1.9 Notwithstanding the provisions of Section 11.2, CI shall
have the right to make or have made a given Proprietary Material, subject to the
provisions of Section 3.6, 6.2 and 6.5 in the event that:

                           (i) MPI fails to deliver such Proprietary Material as
stated on any CI firm purchase order, where such order for Proprietary
Material(s) conforms to the terms and conditions of this Agreement with respect
to:

                                    (a)      the price to be paid for such
                                             Proprietary Material;

                                    (b)      the amount of Proprietary Material
                                             to be delivered;

                                    (c)      the time frame for delivery of the
                                             Proprietary Material;

                                    (d)      the time frame for delivery of
                                             payment for Proprietary Material;

                                    (e)      the specifications for the
                                             Proprietary Material; and

                                    (f)      the location of the delivery of
                                             Proprietary Material;


                                                                               9
<PAGE>   10

and MPI fails to correct such failure within sixty (60) days of a written notice
of deficiency from CI, provided CI is not in default under any other provision
of this Agreement; or

                           (ii) MPI is declared insolvent pursuant to Section
365(n)(1) of the Bankruptcy Code or any similar provision of any controlling
state insolvency law(s);

until such time as MPI resumes manufacturing of such Proprietary Materials in
quantities sufficient to supply CI with Proprietary Materials consistent with
the terms and conditions set forth in this Agreement, and MPI notifies CI that
MPI is prepared to resume exclusive manufacture of such Proprietary Materials.

                  5.1.10 In the event that the provisions of Section 5.1.9
apply, MPI shall transfer to CI that documentation possessed by MPI that would
be reasonably necessary for a person with a Bachelor of Science degree in
organic chemistry and reasonably skilled in the relevant manufacturing and/or
analytical processes, to reproduce and manufacture the Proprietary Material(s)
previously available from MPI under the terms of this Agreement, including
without limitation, lists of raw materials, and their commercial sources,
synthesis and purification protocols, and methods and procedures for the
characterization and quality control. To the extent such documentation contains
Confidential Information of MPI, CI shall institute reasonable measures to
prevent its unauthorized use and/or disclosure.

         5.2 Supply. Subject to the terms and conditions of Section 5.1 and this
Section 5.2, MPI shall manufacture Licensed Materials in accordance with CI
Specifications, and shall supply CI with CI's requirements for Licensed
Materials. At CI's request, MPI shall also supply CI with Non-Proprietary
Material(s) subject to Sections 5.2.4, 5.2.5 and 5.5 (i) non-exclusively as
Stock Item(s) or (ii) exclusively as a Custom Product(s) or non-exclusively,
pursuant to Section 5.2.5, at CI's option. CI shall have the right to repackage
Licensed Materials (subject to the terms and conditions of Sections 2.1-2.3, 6.2
and 6.5), and Non-Proprietary Materials supplied by MPI hereunder

                  5.2.1 Forecasts. For so long as MPI is supplying Licensed
Materials to CI hereunder, at least thirty (30) days prior to the start of any
calendar quarter ("Q1"), CI shall provide MPI with a rolling written forecast of
the quantities of Licensed Materials (on a product-by-product basis) estimated
to be required on a quarter-by-quarter basis for four (4) consecutive quarters
("Q1" to "Q4", respectively). Each forecast shall indicate the estimated
quantities of Licensed Materials. CI will provide such forecasts as a means of
production planning only and such forecasts shall not constitute a binding
obligation upon MPI or CI. CI may also provide forecasts of its estimated
requirements for Non-Proprietary Materials, at its option, if CI desires such
estimates to be included in MPI's production planning for the purposes of
extending the provisions of Sections 5.2.3 to such Non-Proprietary Materials.

                  5.2.2 Form of Order. CI's orders shall be made pursuant to a
written purchase order which is in a form mutually acceptable to the parties.
MPI shall use reasonable efforts to notify CI within ten (10) days from receipt
of an order of its ability to fill quantities ordered thereunder, subject to
Section 5.2.3 below.


                                                                              10
<PAGE>   11

                  5.2.3 Shipping. All Licensed Materials and Non-Proprietary
Materials delivered pursuant to the terms of this Section 5.2 shall be suitably
packed for shipment by MPI, marked for shipment to the destination point
indicated in CI's purchase order. Unless otherwise agreed between the parties in
writing, orders for less than twenty-five (25) units of the same Stock Item for
which MPI has previously received a forecast pursuant to Section 5.2.1 shall be
shipped to CI within five (5) business days of receipt of the order; orders for
twenty-five (25) units or more of the same Stock Item shall be shipped within
thirty (30) days of receipt of the order. The shipment schedules for orders of
Custom Products will be determined at the time such order is placed, in
accordance with MPI's standard completion schedules for custom synthesis. All
Licensed Materials and Non-Proprietary Materials shipped to CI will be
delivered FOB (U.C.C.) the shipping point. All shipping and insurance costs, as
well as any special packaging expenses, shall be paid by CI.

                  5.2.4 Prices. MPI shall provide to CI all Licensed Materials
and Non-Proprietary Materials to CI for use in Finished Products and Services as
follows:

                           (i) MPI shall provide Stock Items at MPI's standard
retail rates as set forth in MPI's website for the period in which the purchase
order was submitted. CI shall be entitled to any standard quantity discounts MPI
offers to industry customers  [*]  .

                           (ii) In addition to the discount set forth above, CI
shall receive an additional discount rebate within thirty (30) days after the
conclusion of a semi-annual period, for aggregate purchases of Licensed
Materials and Non-Proprietary Materials that are Stock Items from the attached
MPI Technology Packages according to the following schedule:

                                    (1) for aggregate annual purchases of less

                                    (2) for aggregate annual purchases of at
least  [*] ; a discount rebate that is  [*]  of such annual aggregate purchases
within the specified range;

                                    (3) for aggregate annual purchases of at
least  [*]  a discount rebate that is  [*]  of such annual aggregate purchases
within the specified range;

                                    (4) for aggregate annual purchases of at
least  [*]  ; a discount rebate that is  [*]  of such annual aggregate purchases
within the specified range.

                           (iii) MPI shall provide Custom Products at prices to
be negotiated in good faith, subject to Sections 5.1.3, 5.1.5, 5.1.7 and 5.2.5.
Prior to determination of the price to be paid for such Custom Product, MPI and
CI shall agree on the degree of exclusivity (pursuant to Section 5.2.5) as well
as the quality control specifications and packaging specifications for such
Custom Product, which agreed specifications shall become the CI Specifications
for such Custom Product, and in the event such Custom Product shall become a
Stock Item, subject to Sections 5.1.3 and 5.2.5, for such Stock Item. Such
Custom Products shall not be included in the annual aggregate purchases



     "CONFIDENTIAL [*] CERTAIN CONFIDENTIAL INFORMATION CONTAINED IN THIS
DOCUMENT, MARKED BY BRACKETS, HAS BEEN OMITTED AND FILED SEPARATELY WITH THE
SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 406 OF THE SECURITIES ACT
OF 1933, AS AMENDED."


                                                                              11
<PAGE>   12

that qualify for the discount rebate, unless and until such Custom Products
shall become available as Stock Items.

                  5.2.5 Prior to MPI accepting an order for a Custom Product, CI
and MPI shall agree in writing whether MPI may convert such Custom Product into
a Stock Item or produce it as a custom product for other party/ies, without
further approval from CI, to address CI's concerns about preserving CI's trade
secrets and MPI's concerns about maintaining flexibility in offering MPI's
technology to third parties for uses other than those exclusively licensed to
CI.

                  5.2.6 Invoicing and Payment. MPI shall submit an invoice to CI
upon shipment of Licensed Materials and Non-Proprietary Materials ordered by CI.
All invoices shall be sent to CI's address for notices hereunder and marked
"Attention: Accounting Department." Each such invoice shall state CI's aggregate
price therefor in a given shipment, plus any insurance, taxes or other costs
incident to the purchase or shipment initially paid by MPI but to be borne by CI
hereunder. Payment shall be made within thirty (30) days after the invoice is
sent to CI.

         5.3 Product Acceptance/Returns.

                  5.3.1 Unless agreed otherwise in writing prior to or
concurrently with acceptance of an order in accordance with Section 5.2.2, any
Licensed Materials and Non-Proprietary Materials supplied hereunder shall
conform at the time of shipment to MPI's internal specifications for research
grade reagents and packaged according MPI's internal packaging protocols.

                  5.3.2 Unless agreed otherwise in writing prior to or
concurrently with acceptance of an order in accordance with Section 5.2.2, any
Custom Products supplied hereunder shall conform at the time of shipment to CI
Specifications.

                  5.3.3 The parameters for evaluating the performance of
Licensed Materials in a particular application undertaken by CI are beyond the
control of MPI and, while such parameters may determine the suitability of
materials for such application, such parameters shall not be used to determine
acceptance of materials. Only written specifications agreed to between the
parties shall be used to determine acceptance of materials supplied by MPI.

                  5.3.4 Each shipment of Licensed Materials and Non-Proprietary
Materials hereunder shall be accompanied by a certificate of analysis for each
lot therein as well as such customs and other documentation as is necessary or
appropriate for shipment of materials from MPI to CI.

                  5.3.5 MPI will provide, upon CI's request, those test
procedures and test data that are the basis for the certificate of analysis
pertaining to Licensed Materials and Non-Proprietary Materials.

                  5.3.6 Without limiting the foregoing, if any Licensed
Materials or Non-Proprietary Materials supplied hereunder fail to conform to the
applicable CI Specifications or certificate of analysis, then CI shall promptly
notify MPI and present reasonable evidence to MPI of such nonconformity, if
requested to do so. Subject to the limitations in Sections 5.1, 5.2.4, 5.3.1,
5.3.2 and 5.3.3, MPI agrees to replace, at no additional expense to CI, such
nonconforming Licensed


                                                                              12
<PAGE>   13

Materials or Non-Proprietary Materials with conforming product within thirty
(30) days after receipt of CI's notification under this Section 5.3.

                  5.3.7 In the event that MPI disputes CI's evidence of
nonconformity, MPI may, at its own expense, request that an independent third
party tester selected by the parties analyze any unit of Licensed Materials or
Non-Proprietary Materials rejected by or on behalf of CI for nonconformity and,
if the independent third party tester determines that any such unit of Licensed
Materials or Non-Proprietary Materials was conforming, then CI shall be
responsible for payment of such units and for such analysis.

                  5.3.8 All returns of Licensed Materials and Non-Proprietary
Materials shall be in accordance with a mutually agreeable product return
protocol.

         5.4 Allocation. In the event that MPI is unable (due to force majeure
or otherwise) to supply both MPI's worldwide requirements of Licensed Materials
or Non-Proprietary Materials, and quantities of such Materials forecast pursuant
to Section 5.2.1 and ordered by CI under Section 5.2.2 above, MPI shall allocate
the quantities of such Licensed Materials or Non-Proprietary that MPI has in
inventory, and that MPI is able to produce, so that CI receives at least its
proportional share of available supplies as determined based on reasonable
forecasts of the requirements of CI, MPI and other third parties (taking into
consideration past requirements for such Materials relative to past forecasts).

         5.5 Compliance with Regulatory Agency Requirements. MPI shall comply
with all laws and regulations applicable to the manufacture of Licensed
Materials and Non-Proprietary Materials. Upon CI's prior written approval, such
approval not to be unreasonably withheld, CI shall reimburse MPI up to $400 for
each low volume exemption ("LVE") filing required for non-research use, in
performance of MPI's obligations hereunder. Non-Proprietary Materials for which
such non-research use is intended shall be identified by CI prior to such
non-research use, for determination of such LVE filing requirement and for
inclusion in Exhibit C attached hereto.


                                    ARTICLE 6
              OWNERSHIP OF INTELLECTUAL PROPERTY AND PATENT RIGHTS

         6.1 Patent Prosecution. MPI shall control, at its sole expense, the
prosecution and maintenance activities pertaining to MPI Patents, using counsel
of its choice and in such countries as it deems appropriate.

         6.2 Patent Marking. CI shall use reasonable efforts to mark
advertisements, labels, and product literature that pertain to Finished Products
to mention the patent number of MPI Patents or a statement of pending patent
status, and a statement to the effect that Licensed Materials are limited to use
in the Field only.

         6.3 Patent Enforcement. If either party reasonably believes that any
MPI Technology Package is infringed or misappropriated by a third party or is
subject to a declaratory judgement action arising from such infringement, such
party shall promptly notify the other party. Both parties shall use their best
efforts in cooperating with each other to terminate such infringement or


                                                                              13
<PAGE>   14

misappropriation without litigation. If such efforts without litigation are
unsuccessful, prosecution of a third party for the infringing use of MPI's
Technology Package may be undertaken.

                  6.3.1 MPI Initiating Enforcement Actions. MPI shall have the
initial right (but not the obligation) to enjoin such misappropriation, to
enforce the MPI Patents with respect to such infringement, or to defend any
declaratory judgment with respect to the MPI Technology Package (for purposes of
this Section 6.3, any such action is herein after referred to as an "Enforcement
Action"). MPI shall keep CI reasonably informed of the progress of any such
Enforcement Action, and CI shall have the right to participate with counsel of
its own choice at its own expense.

                  6.3.2 CI Initiating Enforcement Actions. In the event that MPI
fails to initiate an Enforcement Action to protect MPI Technical Information or
to enforce the MPI Patents against a commercially significant infringement by a
third party, which infringement or misappropriation consists of the manufacture,
Sale or use of a product in the Field, within one hundred twenty (120) days of a
request by CI to initiate such Enforcement Action, CI may initiate an
Enforcement Action against such infringement with MPI's prior written approval,
which approval shall not be unreasonably withheld or delayed, and at CI's
expense. MPI's approval for initiation of an Enforcement Action notwithstanding,
CI shall not enter into any settlement of an Enforcement Action initiated by CI,
if such settlement admits the unpatentability, invalidity or unenforceability of
any MPI Patent without the written consent of MPI.

                  6.3.3 Recoveries. If a party undertakes an Enforcement Action
at its own expense, it shall be entitled to 100% of the recoveries therefrom. If
the other party chooses to join such Enforcement Action at its own expense, the
parties shall agree in advance what the apportionment of expenses and recoveries
shall be.

         6.4 Defensive Actions. If a claim, suit or proceeding (any for purposes
of this Section 6.4, an "Action") is brought against CI or MPI (the "Subject
Party") and such Action is directed to the subject of a patent or patent
application within the MPI Patents, the Subject Party shall promptly notify the
other party. As between the parties to this Agreement, the Subject Party shall
be entitled to control the defense in any such action(s); provided that the
other party shall have the right to participate in the defense or settlement
thereof at its own expense with counsel of its own choosing. Except as agreed in
writing by the other party, the Subject Party shall not enter into any
settlement of an Action, if such settlement admits the unpatentability,
invalidity or unenforceability of any MPI Patent. The Subject Party agrees to
keep the other party hereto reasonably informed of all material developments in
connection with any Action.

         6.5 MPI Trademarks. CI shall use trademarks of MPI to identify Licensed
Materials that are supplied by MPI. CI shall not use MPI's trademarks to
identify Licensed Materials if such Licensed Materials contain no components
that are supplied by MPI and CI shall not use any other of MPI's trademarks,
trade names, slogans, logos, or packaging designs (or any similar trademarks,
trade names, slogans, logos, or packaging designs), except where such use is
specifically authorized in writing by MPI in advance.


                                                                              14
<PAGE>   15

                  6.5.1 CI shall properly use all such trademarks and shall
acknowledge MPI's ownership of such trademark(s) in advertisements,
publications, and product literature. Where space is available, product labels
shall acknowledge MPI's ownership of such trademarks.

                  6.5.2 CI shall not register nor assist a third party to
register any of MPI's trademarks, trade names, slogans, logos, or packaging
designs (or any similar trademarks, trade names, slogans, logos, or packaging
designs) except as specifically authorized in writing by MPI in advance.

         6.6 Reservation. Other provisions of this Article 6 notwithstanding, in
the event that any third party shall file an infringement suit against either
party, where the suit alleges that a Finished Product or Service, only when used
as offered for Sale by CI, infringes the patent of such third party, (i.e. it is
the particular method of use offered by CI that is the issue, rather than the
materials furnished by MPI); then CI shall have the option to discontinue such
use or to indemnify and hold MPI harmless from and against all proceedings and
claims by third parties arising out of the use or sale of Finished Products or
Services in the allegedly infringing manner. Where the suit alleges that it is a
Licensed Material that infringes the patent of such third party, MPI shall have
the option to waive its exclusive right to the manufacture of such Licensed
Material in accordance with Section 5.1.8 above, but not to otherwise limit the
access of CI to such Licensed Material.

                                    ARTICLE 7
                         REPRESENTATIONS AND WARRANTIES

         7.1 MPI Warranties. MPI hereby represents, warrants and covenants to CI
that (i) it has the full right and authority to enter into this Agreement and
grant the rights and licenses granted herein; (ii) it has not previously granted
and will not grant any rights in conflict with the rights and licenses granted
herein; (iii) to MPI's knowledge and belief, MPI is not aware of any third party
intellectual property rights that are infringed by Licensed Materials, and there
are no existing or threatened actions, suits or claims pending against it with
respect to its right to enter into and perform its obligations under this
Agreement; and (iv) to MPI's knowledge and belief, the Licensed Materials are
useful for the methods described or claimed in MPI Patents, but MPI MAKES NO
WARRANTIES OR REPRESENTATIONS OF MERCHANTABILITY OR SUITABILITY FOR A PARTICULAR
PURPOSE.

         7.2 CI Warranties. CI hereby represents, warrants and covenants that it
has the full right and authority to enter into this Agreement.


                                    ARTICLE 8
                                 CONFIDENTIALITY

         8.1 Confidential Information. Except as expressly provided herein, the
parties agree that, for the term of this Agreement and for five (5) years
thereafter, the receiving party shall not publish or otherwise disclose and
shall not use for any purpose any information furnished to it by the other party
hereto pursuant to this Agreement which if disclosed in tangible form is marked
"confidential" or with other similar designation to indicate its confidential or
proprietary nature, or if disclosed


                                                                              15
<PAGE>   16

orally is confirmed as confidential (any oral disclosures must be identified in
writing as confidential within (30) thirty days of such disclosure) or
proprietary by the party disclosing such information at the time of such
disclosure (collectively, "Confidential Information"). Notwithstanding the
foregoing, it is understood and agreed that Confidential Information shall not
include information that, in each case as demonstrated by written documentation:

                  8.1.1 was already known to the receiving party, other than
under an obligation of confidentiality, at the time of disclosure;

                  8.1.2 was generally available to the public or otherwise part
of the public domain at the time of its disclosure to the receiving party;

                  8.1.3 became generally available to the public or otherwise
part of the public domain after its disclosure and other than through any act or
omission of the receiving party in breach of this Agreement; or

                  8.1.4 was subsequently lawfully disclosed to the receiving
party by a person other than a party hereto or developed by the receiving party
without reference to any information or materials disclosed by the disclosing
party.

                  8.1.5 Sections 8.1.1 through 8.1.4 notwithstanding,
information disclosed by one party to another shall still be deemed Confidential
Information of the disclosing party subject to the protection of this Section
8.1 if such disclosed information is

                           (i) a specific embodiment that is only generally
described by information in the public domain or the receiving party's
possession or

                           (ii) a combination that can be pieced together and
reconstructed from multiple sources, none of which shows the whole combination
of materials, its principle of operation, and method of use.

         8.2 Permitted Disclosures. Notwithstanding the provisions of Section
8.1 above, each party hereto may use and disclose the other's Confidential
Information to the extent such use and disclosure is reasonably necessary, in
defending litigation, complying with applicable governmental regulations,
submitting information to tax or other governmental authorities or in exercising
its rights hereunder, provided that if a party is legally required to make any
such disclosure of the other party's Confidential Information, to the extent it
may legally do so, it will give reasonable advance written notice to the latter
party of such disclosure and, save to the extent inappropriate in the case of
patent applications, will use its reasonable efforts to secure confidential
treatment of such Confidential Information prior to its disclosure (whether
through protective orders or otherwise).


                                    ARTICLE 9
                                 INDEMNIFICATION

         9.1 Indemnification of CI. MPI shall indemnify each of CI and its
directors, officers and employees and the successors and assigns (only as
authorized under Section 11.7) of the foregoing


                                                                              16
<PAGE>   17

(collectively, the "CI Indemnitees"), and hold each CI Indemnitee harmless from
and against any and all liabilities, damages, settlements, claims, actions,
suits, penalties, fines, costs or expenses (including, without limitation,
reasonable attorneys' fees and other expenses of litigation) incurred by any CI
Indemnitee arising from or occurring as a result of any claim, action, suit, or
other proceeding brought by third parties against a CI Indemnitee arising from
or occurring as a result of the gross negligence or willful tortious misconduct
of a MPI Indemnitee.

         9.2 Indemnification of MPI. CI shall indemnify each of MPI and its
directors, officers and employees and the successors and assigns of the
foregoing (collectively, the "MPI Indemnitees"), and hold each MPI Indemnitee
harmless from and against any and all liabilities, damages, settlements, claims,
actions, suits, penalties, fines, costs or expenses (including, without
limitation, reasonable attorneys' fees and other expenses of litigation)
incurred by any MPI Indemnitee arising from or occurring as a result any claim,
action, suit, or other proceeding brought by third parties against a MPI
Indemnitee arising from or occurring as a result of the gross negligence or
willful tortious misconduct of a CI Indemnitee.

         9.3 Procedure. A party (for purposes of this Section 9.3, the
"Indemnitee") that intends to claim indemnification under any provision of this
Agreement shall: (i) promptly notify the indemnifying party (the "Indemnitor")
in writing of any claim, action, suit, or other proceeding brought by third
parties in respect of which the Indemnitee, or their directors, officers,
employees, successors or assigns intend to claim such indemnification hereunder;
(ii) provide the Indemnitor sole control of the defense and/or settlement
thereof, and (iii) provide the Indemnitor, at the Indemnitor's request and
expense, with reasonable assistance and full information with respect thereto.
Notwithstanding the foregoing, the indemnity obligation in this Article 9 shall
not apply to amounts paid in settlement of any loss, claim, damage, liability or
action if such settlement is effected without the consent of the Indemnitor, to
the extent such consent is not withheld unreasonably or delayed. Without
limiting the foregoing provisions of this Section 9.3, the Indemnitor shall keep
the Indemnitee reasonably informed of the progress of any claim, suit or
proceeding under this Section 9.3 and the Indemnitee shall have the right to
participate in any such claim, suit or proceeding with counsel of its choosing
at its own expense.

         10.2 Effect of Expiration.

                  10.2.1 Accrued Obligations. Expiration of this Agreement for
any reason shall not release either party hereto from any liability which, at
the time of such expiration, has already accrued to the other party or which is
attributable to a period prior to such expiration nor preclude either party from
pursuing all rights and remedies it may have hereunder or at law or in equity
with respect to any breach of this Agreement.

         10.3 Termination.

                  10.3.1 In the event of a material breach of a party of its
obligations hereunder, the nonbreaching party shall be entitled to terminate
this Agreement upon written notice to the breaching party, if such breach is not
cured within thirty (30) days after written notice is given by the nonbreaching
party to the breaching party specifying the breach.

                  10.3.2 In the event that CI terminates its rights to all MPI
Technology Packages pursuant to Section 2.6, CI may terminate this Agreement
upon sixty (60) days written notice to MPI.

         10.4 Effect of Termination.

                  10.4.1 Accrued Obligations. Termination of this Agreement for
any reason shall not release either party hereto from any liability which, at
the time of such termination, has already accrued to the other party or which is
attributable to a period prior to such termination nor preclude either party
from pursuing all rights and remedies it may have available hereunder or at law
or equity with respect to any breach hereunder.

                  10.4.2 Return of Materials. Upon any termination of this
Agreement, CI and MPI shall promptly return to the other party all Confidential
Information received from the other party (except one copy which may be retained
for archival purposes only).

         10.5 Survival. Sections 5.3, 10.2, 10.4, 11.1 and 11.6, and Articles
6,7,8 and 9 shall survive the expiration or termination of this Agreement for
any reason.


                                   ARTICLE 11
                                  MISCELLANEOUS

         11.1 Governing Law. This Agreement and any dispute arising from the
performance or breach hereof shall be governed by and construed and enforced in
accordance with, the laws of the State of New York, without reference to
conflicts of laws principles.

         11.2 Force Majeure. Nonperformance of any party (except for payment of
amounts due hereunder, and as provided in Section 5.1.9) shall be excused to the
extent that performance is rendered impossible by strike, fire, earthquake,
flood, governmental acts or orders or restrictions, or any other reason,
including failure of suppliers, where failure to perform is beyond the
reasonable


                                                                              18

control of the nonperforming party. Without limiting the foregoing, the party
subject to such inability shall use reasonable efforts to minimize the duration
of any force majeure event.

         11.3 No Implied Waivers; Rights Cumulative. No failure on the part of
MPI or CI to exercise and no delay in exercising any right under this Agreement,
or provided by statute or at law or in equity or otherwise, shall impair,
prejudice or constitute a waiver of any such right, nor shall any partial
exercise of any such right preclude any other or further exercise thereof or the
exercise of any other right.

         11.4 Independent Contractors. Nothing contained in this Agreement is
intended implicitly, or is to be construed, to constitute MPI or CI as partners
in the legal sense. No party hereto shall have any express or implied right or
authority to assume or create any obligations on behalf of or in the name of any
other party or to bind any other party to any contract, agreement or undertaking
with any third party.
