provided, however, that API may not enter into any understanding or contract of
--------  -------
more than (i) six months (twelve months duration if entered into during Contract
Year 5 through Contract Year 10) duration to purchase Black Colorformers from a
third party (other than YK) which has previously supplied such Black
Colorformers or (ii) twelve months duration to purchase Black Colorformers from
a third party (other than YK) which has not previously supplied such Black
Colorformers unless, at the time of the rejection by the Supplier of the
relevant Purchase Notice, the Supplier is unable to provide reasonable
assurances that it will have the capacity or ability to fill Purchase Notices
for the Excess Quantities identified in the relevant Purchase Notice. In the
event that API purchases any

                                       8

<PAGE>

such Black Colorformers from a third party, API shall, on or before the date of
such purchase, deliver to the Supplier (or its authorized designee) a notice
(the "Third Party Purchase Notice") describing the terms and conditions of such
      ---------------------------
third party's agreement to sell such Black Colorformers to API and shall provide
reasonable evidence to the Supplier that such agreement is for the purchase of
no more than the Black Colorformers identified in the rejected portion of the
Purchase Notice on the terms and conditions (including price, quantities and
delivery dates) of such rejected portion of such Purchase Notice.

           (e) Conflicting Terms. If and to the extent that the terms and
               -----------------
conditions of this Agreement conflict with the terms and conditions of any
purchase orders or Purchase Notices submitted by API to the Supplier under this
Section 2.03, the terms and conditions of this Agreement shall control.

           (f) Substitute Products. In the event the Supplier develops a Black
               -------------------
Colorformer that it proposes be substituted for [*] or [*] or any then-existing
Equivalent hereunder in respect of API's obligation to purchase the Guaranteed
Quantities, it shall send to API a test sample of such Black Colorformer and
provide to API information about the properties and characteristics of the
proposed substitute, but excluding information relating to manufacturing
processes. If API agrees that the Black Colorformer is an acceptable substitute,
then such Black Colorformer shall be so substituted as an Equivalent to the
extent that API and the Supplier agree, except that the price shall be
determined according to Section 2.04(b).

           (g) Proposed Equivalents. In the event API or any third party
               --------------------
develops a Black Colorformer that API proposes be substituted for [*] or [*] or
any then-existing Equivalent hereunder in respect of API's obligation to
purchase the Guaranteed Quantities, API shall provide the Supplier and/or YK
with specifications and such know-how and other technical

                                       9

<PAGE>

information in API's possession, which is not protected against disclosure by
bona fide confidentiality restrictions benefiting third parties, as the Supplier
or YK may reasonably request within 15 days after receipt of API's proposal in
order to determine whether such Black Colorformer (a "Proposed Equivalent") can
                                                      -------------------
be an Equivalent hereunder. If the Supplier agrees to manufacture such Proposed
Equivalent, (i) API shall license or sublicense the Supplier and/or YK to
manufacture and supply the same solely for API's Use and (ii) the Proposed
Equivalent shall be deemed to be an Equivalent hereunder to the extent agreed by
API and the Supplier, except that the price shall be determined according to
Section 2.04(b). In no event shall API initiate, continue or conduct any
discussions with any third party (other than MTC or YK) regarding the possible
purchase by API or its subsidiaries of any Proposed Equivalents prior to the
expiration of 60 days from the date that API complies in all material respects
with the first sentence of this Section 2.03(g).

           2.04. Price.
                 -----

                 (a) Basic Products. The price for the Basic Products included
                     --------------
in the Guaranteed Quantities shall be as set forth (i) in Exhibit A hereto for
the first four Contract Years and (ii) in the next paragraph for Contract Years
five through ten, subject to such adjustment as may be agreed pursuant to
Section 2.05 hereof.

                 The price for the Basic Products included in the Guaranteed
Quantities for each of the fifth through the tenth Contract Years shall be the
Current Market Price (defined below) plus [*].

The price for the Basic Products included in the Excess Quantities for each of
the fifth through tenth Contract Years shall be the Current Market Price.

                                       10

<PAGE>

     The "Current Market Price", as that term is used in this Section 2.04(a),
means the price which is to be established pursuant to a meeting (the "Annual
Meeting") to be held annually between representatives of API, Supplier and YK.
The Annual Meeting shall be held during the last Calendar Quarter of the
Contract Year immediately preceding each Contract Year for which the Current
Market Price is to be established (such preceding Contract Year being referred
to as the "Current Contract Year" and such following Contract Year for which the
Current Market Price is to be established being referred to as the "Following
Contract year"), but not later than thirty (30) days prior to the end of such
Calendar Quarter. At each Annual Meeting, Supplier's or YKs representative shall
inform API of (i) [*] and (ii) [*]. The lowest of such prices shall be
established as the Current Market Price for the Following Contract Year unless
API notifies Supplier, not later than at the Annual Meeting, that API is aware
of a lower price that was charged on a regular basis by Supplier, YK or any
other significant supplier of Basic Products, or was offered by Supplier or YK
to be charged on a regular basis on new business, during such Current Contract
Year up to the date of the Annual Meeting, in which case the Current Market
Price shall be such lower price if API provides Supplier with information
evidencing such lower price or if Supplier, in attempting in good faith to
determine the validity any such claim, determines the validity of such claim.

     If the parties disagree regarding the amount of the "Current Market Price"
for the Following Contract Year, such price shall be deemed to be the "Current
Market Price" for the Current Contract Year. Once the "Current Market Price" is
determined, it shall be applied retroactively to the beginning of the Following
Contract Year and the party owing an additional amount or a refund, as the case
may be, shall pay the amount thereof promptly plus interest at eighteen percent
(18%) per annum from the date each payment for Products was due to Supplier.

                                       11

<PAGE>

     The term "regular basis", as used in this Section, shall mean on a regular,
recurring basis and not (A) on a "spot" basis, (B) as a special price in
consideration of past business done or services provided or (C) as some other
special promotion or price not constituting the normal price to be charged to a
non-affiliated customer. The term "significant supplier", as used in this
Section, shall mean an entity which is a recognized specialty chemical
manufacturer of the Products which has the resources and capacity to supply
Basic Products to meet API's quoted requirements on a continuing basis.

           (b) Equivalents. The price for any Equivalent included in the
               -----------
Guaranteed Quantities shall initially be a price to be agreed upon by API and
the Supplier, which shall equal the amount necessary to permit the Supplier to
achieve substantially the same profit margin with respect to the Equivalent as
it expected to achieve with respect to the Guaranteed Quantity for which the
Equivalent is a substitute ("Level Profit Margin"). Until the marginal
                             -------------------
manufacturing cost of an Equivalent stabilizes, its price may be adjusted from
time to time by agreement between API and the Supplier, which adjustment shall
be made in order to maintain a Level Profit Margin. After the parties agree that
the manufacturing cost for an Equivalent has stabilized, the price for such
Equivalent shall be increased at a rate of [*]% per annum from a date agreed
upon by the parties. The price for Equivalents shall be subject to such
adjustment as may be agreed pursuant to Section 2.05 hereof.

     2.05. Price Adjustments. From time to time during the term of this
           -----------------
Agreement, in the event that either API or the Supplier believes that the
Supplier has experienced a significant change in manufacturing costs of the
Products as a result of drastic changes in external economic conditions, such
party shall have the right to give notice to the other party of such event and
to request that the other party discuss with it whether there should be an
adjustment, either up or

                                       12

<PAGE>

down, in the price of one or more of the Products. Promptly after any such
notice is given, the parties shall discuss, in good faith, whether and on what
terms there should be a price adjustment. The party requesting a price
adjustment shall provide reasonable information to the other party to support
its belief that the Supplier has experienced such a significant change. In
discussing whether there should be a price adjustment, the parties shall
consider all relevant factors, including, without limitation, changes in the
costs of labor, materials, freight, taxes and compliance with environmental laws
and regulations. The foregoing agreement of the parties to discuss in good faith
whether to adjust the price of any Product shall in no way constitute a binding
obligation on the part of either party to agree to any request for a price
adjustment or relieve either party of its obligations to perform under this
Agreement.

         2.06. Effect of Imports. If API notifies Supplier that the quantity of
               -----------------
either carbonless or thermal paper sold in the United States during any
particular Contract Year by suppliers based in other countries was in excess of
[*] percent ([*]%) of the total quantity thereof sold in the United States
during such Contract Year, and provides documentation to Supplier establishing
that such is the case, then Supplier and API shall discuss the prices paid by
such foreign-based suppliers for colorformer and shall negotiate in good faith
in an attempt to address the impact of such colorformer prices on API's ability
to compete in the United States with foreign-based suppliers of such carbonless
or thermal paper.

                                   ARTICLE III

                               PERMITTED PURCHASES

         3.01. Permitted Purchases.  API shall not, and shall not permit any of
               -------------------
its wholly owned subsidiaries (each an "API Company") to, purchase any Black
                                        -----------
Colorformers from any suppliers other than the Supplier except as follows
("Permitted Purchases"):
  -------------------

                                       13

<PAGE>

            (a)    Rejected Purchase Notice. In any Contract Year, API and the
                   ------------------------
API Companies shall be entitled to purchase solely for API's Use Black
Colorformers, as to which a Purchase Notice has been rejected by the Supplier,
from suppliers other than the Supplier in accordance with Section 2.03(d).

            (b)    Failure to Supply; Nonconforming Product. Except as otherwise
                   ----------------------------------------
provided herein, API and the API Companies shall be entitled to purchase Black
Colorformers solely for API's Use from suppliers other than the Supplier if and
to the extent that, (i) the Supplier shall fail to fill properly submitted
purchase orders therefor or Purchase Notices that the Supplier has accepted or
(ii) the Supplier shall fail, within 30 days (for Products supplied from Japan)
or within 15 days (for Products supplied domestically) of its receipt from API
of timely notice with respect thereto, to replace any Product supplied hereunder
which does not conform to the warranties set forth in Section 4.01 hereof.

            (c)    [*] Pounds. API and the API Companies shall be entitled to
                   ----------
purchase solely for API's Use up to an aggregate of [*] pounds per Contract Year
of Black Colorformers from suppliers other than the Supplier or YK; provided,
however, that (i) up to, but not more than, [*] pounds per Contract Year may be
comprised of Basic Products and Equivalents, and (ii) up to, but not more than,
[*] pounds per Contract Year may be comprised of Restricted Black Colorformers,
including [*].

            (d)    Custom Coating.  API shall be entitled to purchase,
                   --------------
from third parties, [*] or other Black Colorformers (other than the Basic
Products or Equivalents) specified by Wiggins Teape Appleton plc or its
subsidiaries that do not have their headquarters in North America (the "Parent")
                                                                        ------
for use in paper products produced by API for sale to the Parent and which are,
in turn, intended for resale to third party customers outside of North America.
API shall, at no cost to it,

                                       14

<PAGE>

provide reasonable assistance, subject to confidentiality obligations to third
parties, in any efforts by the Supplier to become an approved supplier of Black
Colorformers so specified by the Parent.

                (e)   Obligations Not Impaired. Notwithstanding anything herein
                      ------------------------
to the contrary, nothing contained in this Section 3.01 shall be construed or
interpreted to impair in any way API's obligation to purchase the Guaranteed
Quantities or to submit Purchase Notices for Excess Quantities pursuant to
Section 2.03 or to purchase Black Colorformer from YK pursuant to Section 3.04.

         3.02.  License. If requested by API, the Supplier shall grant the
                -------
suppliers of the Permitted Purchases under Section 3.01(a), (b) and (c) a
royalty-free, nonexclusive license to use the Transferred Technologies and to
make and sell Products for API's Use for the limited and express purpose of
supplying such Permitted Purchases subject to the prior execution by any such
suppliers of a license agreement (a "License Agreement") substantially in the
                                     -----------------
form attached as Exhibit B hereto; provided, however, that if the supplier of
the Permitted Purchase is Hilton-Davis Company, the license shall relate only to
the patents and patent applications included in the Transferred Technology and
such know-how and trade secrets of which Hilton-Davis has as of the date of this
Agreement. In the event that API proposes to make a Permitted Purchase from a
third party supplier and has requested that the Supplier grant such a license,
API shall provide to the Supplier a License Agreement executed by the third
party supplier with all blanks filled in and a written statement describing the
proposed Permitted Purchase; if, within 15 days of the Supplier's receipt of
such License Agreement, the Supplier has neither (i) executed and returned such
License Agreement to API, nor (ii) given API a written notice stating that the
proposed Permitted Purchase fails to comply with the provisions of Section 3.01,
and specifying the

                                       15

<PAGE>

grounds for such objection, then in such event API shall be entitled to execute
and deliver to the third party supplier such License Agreement in the name of
the Supplier as the Supplier's attorney-in-fact attached hereto as Exhibit D.
If, within 10 days after API's receipt of the Supplier's objections, API and the
Supplier shall fail to resolve any disputes they may have as respects compliance
with Section 3.01, then API may execute and deliver such License Agreement as
the Supplier's attorney-in-fact; provided, however, that API shall pay to the
                                 --------  -------
Supplier an amount equal to 8% of the purchase price for each pound of Product
supplied by the other supplier pursuant to such License Agreement, if it should
be finally determined, in an arbitration or legal proceeding relating thereto,
that the said proposed Permitted Purchase did not comply with Section 3.01 for
reasons substantially similar to those specified by the Supplier in its written
notice. The existence of the remedy provided in the immediately preceding
sentence shall not preclude the Supplier from pursuing other legal or equitable
remedies, whether provided by this Agreement or otherwise. The limited
power-of-attorney granted hereunder shall (i) be solely for the purpose of
executing and delivering a License Agreement and not for any other purpose
(including, without limitation, amending or modifying a License Agreement), (ii)
be irrevocable during the term of this Agreement and shall be revoked upon the
termination hereof and (iii) shall be in a form substantially similar to Exhibit
D attached hereto and shall be executed and delivered by the Supplier to API
along with the execution and delivery of this Agreement. As between API and the
Supplier, API shall be responsible for any failures by such suppliers to comply
with any License Agreement granted in connection with Permitted Purchases
pursuant to Section 3.01(c), and the Supplier shall be responsible for any
failures by such suppliers to comply with any License Agreement granted in
connection with Permitted Purchases pursuant to Section 3.01(a) and (b).

         3.03.  Representation by API. API represents and warrants that neither
                ---------------------
it nor any API Company is required or bound to purchase Black Colorformers from
any other party [except pursuant to that certain agreement dated 1981 between
API and Hilton-Davis Company].

         3.04.  Right of First Negotiation. During the term hereof, if API
                --------------------------
(including for this purpose its affiliates which are headquartered in North
America and its subsidiaries) develops any new Black Colorformers or new
technology related to the manufacture of the same (any of the foregoing, "New
                                                                          ---
Products") that API commercializes for use in carbonless or thermal paper, API
--------
shall not license any third party (other than MTC or YK) to make, use and/or
sell such New Products and shall not discuss any such license with any third
party (other than MTC or YK) except in accordance with the following procedures:
(a) API shall deliver to the Supplier, MTC and YK a notice describing the New
Products in sufficient detail to permit the Supplier, MTC and YK to determine
whether the New Products are commercially practicable for manufacture by the
Supplier, MTC or YK; (b) the Supplier, MTC and YK shall have 30 days from the
receipt of such notice to advise API whether the Supplier, MTC and/or YK are
interested in negotiating the terms of a license with respect to the New
Products; (c) if the Supplier, MTC and/or YK gives notice to API that the
Supplier, MTC and/or YK, as the case may be, are interested in negotiating the
terms of such a license, then API and the Supplier, MTC and/or YK, as the case
may be, shall negotiate in good faith the terms of an exclusive license to make,
use and/or sell, but not have made, the New Products for API's sole benefit
unless otherwise agreed; and (d) if (i) none of the Supplier, MTC or YK, within
said 30-day period, shall have advised API that it is interested in negotiating
the terms of an exclusive license with respect to the New Products or (ii) API
and the Supplier, MTC and/or YK negotiate in good faith for a period of 60 days
from the receipt by API of notice that the Supplier, MTC and/or YK is interested
in negotiating the terms

                                       17

<PAGE>

of an exclusive license with respect to the New Product but are unable to reach
agreement on the terms for such a license, then API shall be permitted to
contact third parties regarding the New Products and to enter into license
agreements with such third parties. In the event API enters into any such
license agreement with any third party, API shall, upon request, grant to the
Supplier, MTC and/or YK a nonexclusive license with respect to the New Products
on terms no less favorable to the Supplier, MTC and/or YK than those contained
in the license granted to any third party; provided, however, that nothing
                                           --------  -------
herein shall require API to grant the Supplier, MTC and/or YK a license with
respect to New Products on terms as favorable as those granted to API's
affiliates. If during the term hereof, API (including for this purpose its
subsidiaries which are headquartered in North America) develops any new
commercial uses for any existing Black Colorformers or any new technology
related to the manufacture of Black Colorformers (any of the foregoing, "Related
                                                                         -------
Technology") that API commercializes for use in record or imaging systems (other
----------
than carbonless or thermal paper), API shall discuss in good faith with the
Supplier, MTC and YK the possibility of licensing the Related Technology to the
Supplier, MTC and/or YK; provided, however, that API shall have no obligation to
                         --------  -------
grant any such license to the Supplier, MTC and/or YK.

                               PRODUCT WARRANTIES

            4.01. Product Warranties. The Supplier represents and warrants to
                  ------------------
API that (a) the Basic Products sold hereunder shall conform to the
specifications set forth on Exhibit C hereto as now in effect and as from time
to time amended by mutual agreement and (b) the Equivalents

18


<PAGE>

and other Black Colorformers sold hereunder shall conform to such specifications
as the Supplier and API agree upon in writing at or prior to the time of sale
thereof.

           4.02.  No Other Warranties. API ACKNOWLEDGES AND AGREES THAT THE
                  -------------------
PRODUCTS ARE SOLD WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES (INCLUDING
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE) EXCEPT FOR
THOSE CONTAINED IN SECTION 4.01 HEREOF.

           4.03.  Warranty Claims. Any notice of breach of warranty must be made
                  ---------------
by API in writing to the Supplier within 90 days of API's receipt of the
Products at issue and no claim for breach of warranty may be made by API
thereafter.

hereunder shall pass to API upon the Supplier's tender of delivery of the
Products, at Harrisburg, as to the Products ordered to be delivered at
Harrisburg, and at Muskegon, as to all remaining Products.

           5.03.  Inspection. API shall promptly inspect Products sold hereunder
                  ----------
upon its receipt thereof and shall promptly, but in no event later than 90 days
after such receipt, notify the Supplier of any shortfalls in quantity or of any
claims of breach of warranty. If API makes any claim of breach of warranty, it
shall (a) hold the goods for a reasonable period for the Supplier's inspection
and provide reasonable access during normal business hours for the Supplier's

                                       19

<PAGE>

inspectors to conduct such inspection or (b), at the Supplier's request and
expense, ship all or part of the delivery back to the Supplier for testing. No
such request by the Supplier to API to return Products to the Supplier for
testing shall be deemed an admission that the Products are non-conforming.

           5.04.  Production Methods. The Supplier shall give 60 day's written
                  ------------------
notice to API prior to any material changes in the production methods used by
the Supplier relating to the Products and shall provide to API such samples and
information about the properties and characteristics of such samples (excluding
information relating to manufacturing processes) as may be reasonably requested
by API in order to permit API to analyze and conduct tests of the Products to be
produced by such new production methods; provided, however, that no such samples
                                         --------  -------
or information need be provided by the Supplier in the event it adopts the
production methods used as of the date of this Agreement by YK to make [*] for
API. API shall advise the Supplier of the results of such analyses and tests
within 30 days of its receipt of such samples. Notwithstanding anything herein
to the contrary, the Supplier shall determine in its sole discretion the
production methods to be employed in the Supplier's manufacturing facilities.

                                  PAYMENT TERMS

          6.01.   Time of Payment. The payment of the purchase price of the
                  ---------------
Products included in the Guaranteed Quantities shall be made to the Supplier or
a designee of the Supplier within 30 days following the tender of delivery
thereof in United States Dollars for the full amount of each sale and purchase
under this Agreement. The payment of the purchase price for such Products in the
United States shall be made by, at API's option, company check written on APIs
accounts or

                                       20

wire transfer. API and the Supplier shall endeavor in good faith to establish an
appropriate payment mechanism as respects any payments to be made outside of the
United States.

         6.02. Taxes. If any additional United States federal or state sales,
               -----
value added or other similar tax or surcharge (except only for customs duties)
is imposed on the sale of the Products to API in such fashion that the Supplier
would be required by the relevant authority to account for the same, the full
amount for which the Supplier is so held accountable shall be charged to and
paid by API; provided, however, that API shall not be obligated to pay or
             --------  -------
discharge any Taxes applicable to the Supplier's, YK's or MTC's production
facilities or operations, income or profits; provided, further, that the
                                             --------  -------
Supplier shall afford reasonable assistance, in the form of supplying data and
information, to API in connection with any challenge or contest by API, as
respects the validity or amount of any tax or surcharge which API shall be

herein of such Products, plus (ii) any Other Damages incurred by the Supplier
arising from or out of API's breach.

         (b) Supplier's Resale. In the event that API commits a Payment Breach

             entitled to receive from API:

             have made from full performance by API of its obligations to pay

             the Supplier arising from or out of API's breach, and minus (B) the

<PAGE>

         (c) Repudiation of Current Obligation. in the event that API wrongfully

  -----------------------
(b) hereof, the Supplier shall be entitled to receive from API:

         (x) the excess of the price provided for herein for such Products over

             by the Supplier arising from or out of such breach, and minus (B)
             any expenses saved in consequence of API's breach; or

         (y) if the remedy provided for in clause (x) is inadequate to put the
             Supplier in as good a position as the Supplier would have been in
             if API had not committed such Current Purchase Breach, then the
             Supplier shall be entitled to receive from API the profit
             (including reasonable overhead) which the Supplier would have made
             from full performance by API of its obligations under this
             Agreement to purchase such Products together with any Other Damages
             incurred by the Supplier arising from or out of such breach.

         (d) Breach Giving Rise to Termination. In the event that API breaches
             ---------------------------------
or otherwise anticipatorily repudiates (in either event by reason of the
occurrence of any of the events entitling the Supplier to terminate this
Agreement) any other obligations hereunder with respect to the purchase of or
offer to purchase (i) all the Guaranteed Quantities and (ii) all Excess
Quantities, if any, as to which API has delivered a Purchase Notice that the
Supplier has previously accepted (the Products described in clauses (i) and (ii)
are referred to as "Future Products" and any such breach is referred to as an
                    ---------------
"API Termination Breach"), and no adequate remedy is available under Section

             Products over the market price, if any, for such Future Products
             determined as of the time and place of such breach, plus (A) any
             Other Damages incurred by the Supplier arising from or out of such

                                       23

<PAGE>

             breach, and minus (B) any expenses saved in consequence of API's
             breach; or

         (y) if the remedy provided for in clause (x) is inadequate to put the
             Supplier in as good a position as the Supplier would have been in
             if API had not committed such API Termination Breach, then the
             Supplier shall be entitled to receive from API the profit
             (including reasonable overhead) which the Supplier would have made
             from full performance by API of its obligations under this
             Agreement to purchase Future Products together with any Other
             Damages incurred by the Supplier arising from or out of such
             breach.

     In calculating damages under this Section 7.01(d), the parties shall assume
that the ratio among the [*] Guaranteed Quantity, [*] Guaranteed Quantity and
Equivalent Guaranteed Quantity (and ratio of such Equivalents within the
Equivalent Guaranteed Quantity) continues to be the same during the remaining
term hereof as those reflected in the immediately preceding notice given under
Section 2.02(b).

         (e) Non-Permitted Purchases. In the event API purchases Black
             -----------------------
Colorformer from a third party in violation of Sections 2.03(c), 2.03(d),
2.03(g), or 3.01, the Supplier shall be entitled to liquidated damages in an
amount equal to 20% of the amount paid, directly or indirectly, by or on behalf
of API to such third party in respect of such Black Colorformer. The parties
specifically agree that the actual loss arising from such breach would be
difficult to prove and that such liquidated damages are reasonable in light of
the anticipated or actual harm.

         (f) Additional Costs and Interest. In the event of any breach the
             -----------------------------
remedy for which is governed by this Agreement, the Supplier's damages shall
also include the costs of enforcing this Agreement (including fees and expenses
of counsel) and interest at the Prime Rate plus 2% from the date of breach.

         (g) Unrecovered Expansion-Related Costs. In acknowledgment of the fact
             -----------------------------------
that the Supplier expanded its production capacity of its plant in Muskegon,
Michigan, and

                                       24

<PAGE>

incurred the costs related thereto in order to satisfy its obligations to supply
the quantity of Products required by the Prior Supply Agreement and expected to
be required by this Agreement, the parties understand that, as a consequence of
any breach hereunder by API, the Supplier may, in an appropriate case, be
entitled to recover as damages unrecovered costs (such as the costs of such
expansion or any additional expansion, costs incurred in connection with the
purchase or lease of additional properties and equipment, the hiring of
additional management and labor and the construction of additional facilities)
that the Supplier actually shall have incurred after the date of this Agreement
in order to satisfy its obligation to sell Products pursuant to the Prior Supply
Agreement and/or this Agreement, if and to the extent such costs are determined
to be appropriate damages under the circumstances; it being further agreed that
API reserves the right to challenge the Supplier's entitlement to such damages
as well as the amount thereof.

         7.02. Remedies Non-Exclusive. Unless otherwise expressly provided in
               ----------------------
this Agreement, the remedies provided for herein in the event of a breach by API
shall be in addition to all other remedies available to the Supplier at law or
in equity, including, without limitation, remedies provided by the Uniform
Commercial Code as from time to time in effect in the State of New York, and by
the common and other statutory laws of the State of New York. To that end, in a
proper case, the Supplier's remedies may include, without limitation, injunctive
relief and replevin and the Supplier's other Damages may include, without
limitation, incidental and consequential damages. Except as otherwise expressly
provided herein, the remedies provided to the Supplier by law, equity or this
Agreement shall be liberally administered to the end that if the Supplier is
injured by a breach hereof the Supplier shall be put in as good a position (but
not unjustly enriched) as it would have been in if API had fully performed.

the market price for such Products determined as of the time and place of such
breach over (ii) the price provided for herein for such Products, plus, (A) any
Other Damages incurred by API arising from or out of the Supplier's breach,
minus (B) any expenses saved in consequence of the Supplier's breach.

as those reflected in the immediately preceding purchase notice given under
Section 2.02(b).

hereto submits to the jurisdiction of, and consents to venue in, any Federal or
state court located in the State of New York in connection with any dispute,
claim, motion, suit or action arising out of or in connection with this
Agreement and, except for disputes, claims or actions subject to arbitration
under Section 11.01, each irrevocably waives any claim that any such court would
be an inconvenient or improper forum for the resolution of such dispute, claim,
motion, suit or action.

                  ----------

respective successors and permitted assigns, but neither this Agreement nor any
of the rights, interests or obligations hereunder shall be assigned by any of

transaction or a series of transactions, all or substantially all of its assets

hereunder and to be substituted for it herein and executes and delivers to the
others an assignment and assumption agreement in form and substance reasonably
satisfactory to the other parties hereto. Notwithstanding anything to the
contrary contained in this Agreement, it is understood and agreed that (a) MTC
anticipates merging with Mitsui Petrochemicals Industries, Ltd. ("MPC"), which
is expected to be the surviving corporation in such merger and to be renamed
"Mitsui Chemicals, Inc.", and (b) the surviving entity of any such merger shall,
as and if renamed and upon effectiveness of such merger, automatically be deemed
to have assumed the rights and obligations of MTC, and be substituted for MTC in
all respects, under this Agreement without any consent by MCI or any of the
other parties to this Agreement or any further action by MCI or any of the other
parties to this Agreement.

their successors and permitted assigns, any rights or remedies under or by
reason of this Agreement.

after it has actual knowledge of the beginning of any such delay, notified the
other party of such delay and of the reason therefor and (b) shall, following
the cessation of the event causing such delay, perform as promptly as
practicable all of its obligations that were temporarily suspended in addition
to, and not in substitution for, its ongoing obligations.

have reasonable access during reasonable business hours to, and the right from
time to time to inspect, copy and make extracts from Licensee's records to the
extent reasonably necessary for the sole purpose of determining whether Licensee
is in compliance with the terms of this Agreement. Such accounting firm shall be
obligated to maintain the confidentiality of Licensee's records and facilities

            ------------------------------------------------------
that any infringement of any of the Patents by or to any third party comes to

infringement, use or disclosure. Thereupon, Licensor in its sole discretion
shall decide what means, if any, shall be employed to eliminate the infringement
of the Patents.

         7. Default.
            -------

            (a) If Licensee uses the license granted hereunder in any way other

         Licensor under the terms hereof for a period of ten days following
         notice from Licensor of such failure, or fails to remedy any other
         violation of this Agreement within ten days of receipt of written
         notice from Licensor of such failure, then Licensor may, at its option,
         terminate this Agreement forthwith. If this Agreement is terminated
         pursuant to this clause (b), Licensor shall thereafter give prompt

         hands of a receiver or trustee in bankruptcy, or if proceedings in
         voluntary or involuntary bankruptcy be instituted on behalf of or
         against Licensee, then Licensor may forthwith terminate this Agreement
         on written notice to Licensee. Licensor shall provide a copy of a
         notice of termination under this clause (c) to API.

         8.  Indemnity; Disclaimers.
             ----------------------

             (a) Nothing in this Agreement shall be construed as (i) a
         representation or warranty by Licensor that the invention of the
         Patents or the manufacture, use or sale or other disposition of
         Licensed Products does not or will not infringe on the patents or other
         property rights of any third party or an assumption of any
         responsibility or liability by Licensor for any such infringement by
         Licensee, (ii) a representation or warranty by Licensor that any
         particular level of technical or commercial results can be obtained by
         the invention of the Patents or (iii) any other representation or
         warranty other than as expressly provided herein.

             (b) Licensee shall indemnify and hold harmless Licensor and its
         agents and employees, from and against any and all claims, actions,
         damages, liabilities, losses, costs and expenses (including fees and
         expenses of counsel) incurred by reason of any claim of third parties
         (including employees of Licensee) arising, directly or indirectly, out
         of the use of the Patents or out of the manufacture, use, sale or other
         disposition of Licensed Products.

         9.  Complete Agreement. This Agreement shall constitute the entire

hereof.

         10. Waiver Discharge, etc. This Agreement may not be waived, amended,

discharged, abandoned, changed or modified in any manner, except by an
instrument in writing signed on behalf of each of the parties hereto by their
duly authorized representative; provided, however, that for purposes of this
                                --------  -------
paragraph, no attorney-in-fact or person acting under a power of attorney shall
be deemed an authorized representative of Licensor.** The failure of any party
hereto to enforce at any time any of the provisions of this Agreement shall in
no way be considered to be a waiver of any such provision, nor in any way be
construed to affect the validity of this Agreement or any part thereof or the
right of any party thereafter to enforce each and every such provision. No

         12. Governing Law: Jurisdiction. This Agreement shall be governed by
             ---------------------------
the laws of the State of New York, without regard to the applicable principles
of conflicts of law. Licensee hereby submits to the non-exclusive jurisdiction
of, and consents to venue in, any Federal or state court located in the State of
New York in connection with any dispute, claim, motion, suit or action arising
out of or in connection with this Agreement and irrevocably waives any claim
that any such court would be an inconvenient forum for the resolution of such
dispute, claim, motion, suit or action.

         13. Severability. If any provision of this Agreement or the application
             ------------
of any such provision to any person or circumstance shall be held invalid,
illegal or unenforceable in any respect by a court of competent jurisdiction,
such invalidity, illegality or unenforceability shall not affect any other
provision hereof.

         14. Successors and Assigns. This Agreement shall be binding on and
             ----------------------
inure to the benefit or the parties hereto and the successors or permitted
assigns of the parties hereto; provided, however, that Licensee may not
                               --------  -------
sublicense or assign this Agreement, in whole or in part, without the prior
written consent of Licensor and any purported assignment without such consent
(which may be withheld without reason) shall be void and shall entitle Licensor
to terminate this Agreement forthwith. Licensor may assign this Agreement, in
whole or in part.

         15. Counterparts. This Agreement may be executed in two or more
             ------------
counterparts all of which shall be considered one and the same instrument and
each of which shall be deemed an original.

         16. No Third Party Beneficiaries. It is hereby agreed that the parties
             ----------------------------
hereto, their successors and permitted assigns shall have the sole right to
enforce the performance of the provisions of this Agreement, and that no other
person shall be entitled to, or shall have any claim, right, title or interest
to or in any such amounts by virtue of this Agreement.

         17. Specific Performance. Licensee acknowledges and agrees that any
             --------------------
material violation by it of its obligations hereunder will cause irreparable
injury for which adequate remedy at law is not available and that any violation
of any obligation under paragraph 2 of this Agreement shall constitute a
material violation of Licensee's obligations for purposes hereof. Accordingly,
Licensee agrees that its obligations hereunder shall be enforceable by an order
for specific performance or restraining the breach thereof from any court of
competent jurisdiction, in addition to any other remedies that Licensor may
have.

         18. Jury Waiver. LICENSEE HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY
             -----------
HAVE TO TRIAL BY JURY OF ANY SUIT, ACTION PROCEEDING, CLAIM, DEFENSE, OR
COUNTERCLAIM ARISING BETWEEN LICENSEE AND LICENSOR HEREUNDER Ox IN CONNECTION
WITH OR RELATING IN ANY WAY TO THIS AGREEMENT.

         19. Costs of Enforcement. Licensee shall reimburse Licensor for the
             --------------------
costs, including reasonable attorneys' fees and disbursements, of enforcing
Licensor's rights under this Agreement.
