Commitments or as otherwise expressly agreed by the parties, nothing in this
Agreement shall be deemed to obligate GWI to purchase any given Primary Product,
or any specific quantity of a Primary Product, under this Agreement.
Notwithstanding the foregoing, GWI shall be obligated with respect to Guaranteed
Revenues as described in Article VI below.

          (b) Additional Purchased Capacity.  To the extent Supplier at any time
              -----------------------------                                     
has available Reactor Gallons in excess of the applicable Contract Reservation
and Flex Capacity amounts, GWI may, by advance written notice of not less than
twelve (12) months and not more than fifteen (15) months, commit to reserve an
amount of such Reactor Gallons ("Additional Purchased Capacity") for (i) a
minimum period of [*] months if the total Reactor Gallons included in such
Additional Purchased Capacity does not exceed by more than [*]% the total
Reactor Gallons which were required to be made available to GWI for the calendar
quarter immediately prior to the beginning of that [*]-month period (calculated
on an annualized basis by multiplying by [*]) or (ii) in any other event, a
minimum period of [*] months In no event shall Supplier be obligated to provide
GWI Additional Purchased Capacity beyond the Primary Term. Reactor Gallons will
be deemed to be available for purchase as Additional Purchased Capacity, taking
into account practical constraints such as maximum efficient utilization, unless
Supplier is conducting good faith negotiations for such capacity which result in
[*] The Profile Plant for the period in which any Additional Purchased Capacity
is reserved by GWI will be revised by the mutual agreement of the parties to
include the Additional Purchased Capacity.

          (c) Release of Reactor Gallons.  By advance written notice to
              --------------------------

period of at least [*] ("Released Capacity") which Supplier would otherwise be
obligated pursuant to this Agreement to make available for the production of
Primary Products. In such event, Supplier shall use its reasonable efforts to
utilize the Released Capacity for other customers of Supplier. If Supplier uses
the Released Capacity for itself or another customer, or otherwise receives any
payment from another customer to reserve such Released Capacity (whether or not
utilized), Supplier shall provide GWI a credit against other amounts payable by
GWI pursuant to this Agreement. If Supplier uses the Released Capacity for
another customer, the credit shall be in an amount equal to the lesser of (i)
[*]% of the price effectively obtained for such Released Capacity, if the
effective price is at least $[*] per Reactor Gallon or (ii) $[*] per Reactor
Gallon of Released Capacity, assuming in either event that such Released
Capacity was utilized for a full calendar year, proportionally adjusted for any
shorter period actually released by GWI. If the price effectively obtained for
the Released Capacity is less than $[*] per Reactor Gallon, Supplier shall
notify GWI in writing and GWI shall have a period of fifteen (15) days from
receipt of such notice to elect, in its sole discretion, to retain rights to the
Released Capacity and to obligate Supplier to make it available for the
production of Primary Products. The effective price per gallon of Released
Capacity shall be determined in good faith by the mutual agreement of the
parties, taking into account all amounts (other than amounts equal to Supplier's
costs for any materials calculated in a manner consistent with the provisions of
the second sentence of Section 5.2(a)) paid by the customer to Supplier for such
products), divided by the aggregate Reactor Gallons required to produce such
products delivered by Supplier to that customer or otherwise reserved for that
customer, or in the case such Released Capacity is utilized by Supplier for its
own products, the credit shall be $[*] per Reactor Gallon. In determining such
effective price, the parties shall consider and appropriately

(d)  Does not include Reactor Gallons utilized by Supplier to manufacture
     Specialty Products in these periods.

The following two tests shall be applied to determine if Supplier shall be
obligated to supply all Products designated within a given Binding Primary
Commitment as provided in notes (b) and (c) above:

          (i) In order to determine whether Firm Capacity Committed for a given
calendar quarter falls with the Contract Reservation for that period, the
Reactor Gallons for each calendar quarter covered by Firm Capacity Committed,
must be equal to or less than the Contract Reservation for the applicable
calendar quarter, plus any Additional Purchased Capacity for that period, on an
annualized basis, [*] and

          (ii) In order to determine whether the Reactor Gallons required to
produce the volumes of Primary Products for each calendar quarter covered by the
Binding Primary Commitment could be produced within the Firm Capacity Committed
for that quarter, the Reactor Gallons required to produce the Primary Products
for that calendar quarter (including volumes projected for any non-binding
portion of the forecast falling within a calendar quarter covered by the Primary
Binding Commitment), based on the Reactor Gallon Factors shown in Schedule
                                                                  --------

Commitments during that calendar year and (ii) if applicable, the volume of
Primary Products projected by GWI for the remainder of that calendar year in the
nonbinding portion of the then current forecast can be manufactured within the
parameters of the applicable Profile Plant.  This determination will be made
using the linear programming model described in Schedule 2.4(b)(ii) attached

              -----------------------------------                             
Commitments are consistent with customary lead times for Materials procurement,
Supplier shall be obligated to produce Primary Products in accordance with the
terms of this Agreement.  Schedule 2.4(c) attached hereto and incorporated
                          ---------------                                 
herein by reference sets forth the agreed upon customary lead times for
procurement of Materials with lead times of three (3) months or longer. The
parties acknowledge, however, that occasional delays in the availability of
Materials beyond the reasonable control of Supplier may from time to time occur.
Provided that Supplier maintains an inventory of Materials consistent with the
parameters set forth in Section 8.3 below, the Delivery Dates for any Primary
Products and Secondary/Steriles Products affected by such a delay shall be
extended to the earliest practicable date following the date that the necessary
Materials become available.

          2.5 Effect of Certain Activities.  If the activities of GWI
              ----------------------------                           
conducted at the Facility pursuant to the Environmental Agreement cause a loss
of Reactor Gallon capacity (based on the manner of operations at the Facility
immediately prior to the Effective Time), one-half of such lost Reactor Gallons
shall be charged against the Contract Reservation for the calendar year in
which such loss occurs. To support any assertion by Supplier of lost capacity,
Supplier shall provide

reasonable substantiation (A) of Supplier's lost revenue as a consequence of
such loss of Reactor Gallons caused by GWI's activities, and (B) that such lost
hours cannot otherwise reasonably be recovered or replaced by Supplier [*]
without additional cost to Supplier. Otherwise, only those Reactor Gallons

Clinical Materials, Replenishment Forecast or a PO for Primary Inventory, or
other factors that:  (i) there are not sufficient volumes of Primary Products in
Primary Inventory to support Supplier's obligations to ship Secondary/Steriles
Products or Clinical Materials under Article III or fill POs for Primary
Products out of Primary Inventory at the times and in the quantities required
under this Agreement or (ii) the requirements for Primary Products cannot be met
within the applicable Contract Reservation plus Additional Purchased Capacity
plus Flex Capacity or within the Profile Plant, Supplier shall promptly notify
GWI and provide GWI with supporting information relating to Supplier's
determination.   Supplier's notice under this Section 4.3(a) must be given no
less than fifteen (15) days after obtaining information indicating those
problems.

          (b) GWI Notice.  If GWI determines following receipt of notice from

Supplier under Section 4.3(a) above or otherwise that, based on information
available to it, Supplier is unlikely to be able to schedule production for
Primary Products needed to support Supplier's obligations under this Agreement
or the requirements for Primary Products cannot be met within the applicable
Contract Reservation plus Additional Purchased Capacity plus Flex Capacity or
the Profile Plant, GWI shall inform Supplier and provide Supplier with
supporting information relating to GWI's determination.  Nothing contained in
this Section 4.3(b) shall, however, relieve Supplier from its obligations to
deliver a notice required by Section 4.3(a) above or to supply Products in
accordance with the terms of this Agreement and the priority of orders as
determined by GWI under Section 4.3(c) below.

to be able to schedule production as indicated in Section 4.3(b) above, then GWI
shall advise Supplier of the priority of production within the Primary Facility
for GWI's Binding Primary Commitments, Binding Secondary/Steriles Commitments,
POs for Clinical Materials or for Primary Inventory and Replenishment Products.
If a change in a Replenishment Forecast previously delivered by GWI, the
issuance by GWI of a new PO for Secondary/Steriles Products or for Primary
Products from Primary Inventory or other causes under GWI's primary control (but
not under Supplier's control) is the basis for the delivery of such notice, the
parties' obligations with respect to the production, purchase and sale of
Products, including without limitation obligations with respect to service
level, shall be modified in accordance with the adjustments in scheduled
delivery dates made by GWI pursuant to this Section 4.3.

          4.4 Cooperation of the Parties.  In recognition of the fact that
              --------------------------                                  
GWI's business is dynamic and evolving based on market demand, regulatory
approvals and other factors,  Supplier shall in good faith, but subject to the
provisions of this Agreement, seek to accommodate any GWI request to manufacture
quantities of Products in excess of the Supplier's obligations hereunder, on
commercially reasonable terms, so long as such request is reasonably related to
marketing of, supply of or demand for the Products, and such manufacturing
activities will not have a material adverse impact on Supplier's other business
activities.

          The Conversion Charge for each New Presentation shall be recalculated
following the [*] the New Presentation is supplied under this Agreement (or
until that New Presentation is no longer supplied, whichever first occurs), [*]
by Supplier with respect to that New Presentation and the actual unit volumes of
that New Presentation with Delivery Dates during the period. Incremental costs
used in the recalculation shall include only the types of costs included in the
initial calculation, and only increases or decreases therein shall be reflected
in the recalculation. If the recalculated Conversion Charge exceeds the
Conversion Charge calculated prior to the commencement of supply of any such New
Presentation, GWI shall promptly pay to Supplier an amount equal to the excess
times the number of units of that New Presentation with Delivery Dates in such
period. If the recalculated Conversion Charge is less than the Conversion Charge
calculated prior to the commencement of supply of any such New Presentation,
Supplier shall credit to GWI an amount equal to the difference times the number
of units of such New Presentation with Delivery Dates in such period on
Supplier's next invoices for Products until fully recovered. The amount of any
credits not applied against invoices to GWI as of the Termination Date shall be
paid by Supplier to GWI within [*] the Termination Date.

day of each April, July, October and January during the Term of this Agreement
(other than October 10, 1997), Supplier shall deliver to GWI Supplier's good-
faith estimate of the aggregate amount paid by Supplier to purchase Designated
Materials purchased for Products shipped under the terms of this Agreement
during that calendar year (or, in the case of January, the immediately preceding
calendar year) through the end of the immediately preceding calendar quarter. In
the event that such estimate less any payments under this Section made through
such date varies from the amount calculated by multiplying [*] costs for the
Designated Materials as provided in Schedule 5.2(c) attached hereto and

incorporated herein by reference by the volume of the Designated Materials
purchased for Products shipped by Supplier for the time period in question by an
amount greater than [*] then Supplier shall, as the case may be, either deliver
an invoice to GWI for the shortfall, payable within [*] receipt by GWI, or
provide GWI with one or more credits in the aggregate amount of the overpayment
on Supplier's next invoices for Products until fully recovered.  The amount of
any credits not applied against invoices to GWI as of the Termination Date shall
be paid by Supplier to GWI within [*] the Termination Date.  In this Section
5.2(c), "Materials purchased for Products shipped" shall include the Designated
Materials purchased for Primary Products and Secondary/Steriles Products,

year during the Term of this Agreement, Supplier shall prepare and deliver to
GWI a final accounting of its actual costs for all Materials actually utilized
in Products shipped under the terms of this Agreement the previous year,
together with verification of the actual costs in a manner reasonably
acceptable to GWI. In this Section 5.2(d), "Materials actually utilized in
Products shipped" shall include Materials actually utilized in the manufacture
of Primary Products and Secondary/Steriles Products, including without
limitation, Replenishment Production, that were shipped and invoiced to GWI
during the applicable period. GWI shall have [*] receipt of the required
detailed schedule to notify Supplier in writing of its acceptance thereof or
of any objection thereto. If a written objection is made by GWI and not
resolved by the parties within [*] issuance by GWI, then a Selected Accounting
Firm shall conclusively determine the amount of Supplier's Materials costs for
the prior year. If the aggregate actual Materials costs exceed that paid by
GWI pursuant to (i) invoices for the Products as provided in Section 5.2(b),
and (ii) Section 5.2(c) above, GWI shall pay the difference to Supplier within
[*] the final determination thereof and receipt of an invoice from Supplier
for such amount. If the aggregate actual Materials costs are less than the
total payments made by GWI pursuant to such invoices and Section 5.2(c) above,
then Supplier shall provide GWI with one or more credits in the aggregate
amount of the overpayment on Supplier's next invoices for Products until fully
recovered. The amount of any

all Products through December 31, 2001 in the periods shown below and payments
for Transition of Products made to Supplier pursuant to Section 18.3 of this
Agreement shall be not less than the aggregate annual amounts as follows
("Guaranteed Revenues"):

               For the period ending December 31, 1997    $ 77.0 million
               For the year ending December 31, 1998      $166.4 million
               For the year ending December 31, 1999      $ 94.0 million
               For the year ending December 31, 2000      $ 72.6 million
               For the year ending December 31, 2001      $ 22.6 million

Conversion Charges for Products shall be credited toward GWI's Guaranteed
Revenues obligation as of the Delivery Date or, in the case of Replenishment
Products, as of the date on which shipment to GWI would be required to meet
Supplier's obligations under Section 3.2.  Conversion Charges for Primary
Products required for use in Secondary/Steriles Products shall, for purposes of
this Section 6.1 and Sections 6.2 and 6.3 below, be treated as part of the
Conversion Charge for the Secondary/Steriles Products regardless of how
designated on the applicable invoice.  The Conversion Charges with respect to
Products for which the Delivery Date falls in one year, but which were not
delivered until a subsequent year as a result of Supplier not timely making
available the Products for shipment (as required in Sections 2.2(c), 3.2(c) or
3.3(b) above) without GWI's consent, shall be credited in the year in which the
Delivery Date fell.  Any amounts payable by GWI to Supplier pursuant to Section
18.3 shall be credited against GWI's Guaranteed Revenue obligations as of the
invoice date.

          6.2  Interim Payments.
               ---------------- 

          (a) By the tenth (10th) day of each month during the Term of this
Agreement Supplier will deliver to GWI Supplier's good faith estimate of the
aggregate Conversion Charges for that calendar year (or, in the case of January,
the immediately preceding calendar year) through the 

                                      45
<PAGE>
 
end of the immediately preceding month.  GWI shall, within 30 days of its
receipt of an invoice, pay to Supplier the amount if any by which the Guaranteed
Revenues for the applicable calendar year through the end of such month
(assuming, except as provided in Section 6.2(b) below, that Guaranteed Revenues
are earned and accrued in twelve equal monthly installments) exceed the
cumulative aggregate Conversion Charges for Products with Delivery Dates in the
applicable calendar year through the end of such month.  All payments made to
Supplier pursuant to this Section 6.2 shall be credited towards GWI's Guaranteed
Revenue obligation.

          (b) For purposes of the interim payments to be made pursuant to
Section 6.2(a) above, it shall be deemed that the Guaranteed Revenues for 1998
are earned as follows:

          For each month ending on or before June 30, 1998    [*] million
          For each month after June 30, 1998 and on or before
           December 31, 1998                                  [*] million

          (c) For purposes of the interim payments to be made pursuant to
Section 6.2(a) above, it shall be deemed that the Guaranteed Revenues for 2001
are earned as follows:

          For each month ending on or before June 30, 2001    [*] million
          For each month after June 30, 2001 and on or before
           December 31, 2001                                  [*] million
          
          6.3  Annual Accounting.
               ----------------- 

          (a) On or before March 30 of each year during the Term of this
Agreement, Supplier shall prepare and deliver to GWI a final accounting of the
aggregate Conversion  Charges hereunder for the preceding calendar year.

          (b) GWI shall have thirty (30) days from receipt of the final
accounting to notify Supplier in writing of its acceptance thereof or of any
objection thereto.  If a written objection is made by GWI and not resolved by
the parties within sixty (60) days after issuance by GWI, then Selected
Accounting Firm shall conclusively determine the amount of the aggregate
Conversion Charges for the prior year.  GWI shall pay to Supplier within thirty
(30) days after receipt of an invoice therefor (or following the final
determination if GWI issues an objection) the amount, if any, by which the
Guaranteed Revenues specified in Section 6.1 above for such year exceed the
aggregate Conversion Charges for that year, taking into account all payments
made under Section 6.2 above.  If the aggregate Conversion Charges for that
year, plus all payments made under Section 6.2 above, exceed accrued Guaranteed
Revenues, then Supplier shall provide GWI with one or more credits on Supplier's
next invoices for the Products as provided below.  The aggregate amount of such
credits shall be equal to (i) all of the payments made pursuant to Section 6.2
during the immediately preceding year, if the aggregate Conversion Charges
exceed Guaranteed Revenues or (ii) the amount by which all the payments made
pursuant to Section 6.2 during the immediately preceding year, plus the
aggregate Conversion Charges exceed Guaranteed Revenues, if the aggregate
Conversion Charges were less than Guaranteed Revenues.  The amount of any
credits not applied against invoices to GWI as of the Termination Date shall be
paid by Supplier to GWI within thirty (30) days after the Termination Date.

          6.4  Secondary/Steriles Allowance.  GWI shall credit against its
               ----------------------------                               
Guaranteed Revenue obligation for a given year Conversion Charges for Primary
Products used in Secondary/Steriles Products which such Primary Products were or
should have been manufactured by Supplier in such year to meet delivery
requirements for Replenishment Production or Delivery 

                                      47

Dates in that year. In no event, however, shall GWI receive a credit against
Guaranteed Revenues for the same Conversion Charge twice.

          6.5  Required Payment.  During the term of this Agreement, GWI's
               ----------------                                           
obligation to pay Guaranteed Revenues under this Article VI shall remain in
effect except as expressly provided in Sections 20.5(b) or 24.3.

                            MANUFACTURE OF PRODUCTS

          7.1  Specifications.
               -------------- 

          (a)  General.  Supplier shall manufacture, test, package, label and
               -------                                                       
deliver all Products in accordance with the Specifications as revised from time
to time in accordance with the provisions of this Agreement.  GWI represents
that the Specifications in Schedule 7.1(a) attached hereto and incorporated
                           ---------------
herein by reference (i) with respect to Products other than TPMA Products, are
GWI's specifications for the Products identified on Schedule 7.1(a) immediately
                                                    --------------- 
prior to the Effective Time and (ii) with respect to TPMA Products, are the
Specifications in effect under the applicable TPMA immediately prior to the
Effective Time.

          (b)  GWI Requested Changes.  GWI shall be entitled to change the
               ---------------------                                      
Specifications for a Product from time to time, and Supplier shall make and
validate all revisions to the Specifications requested by GWI in accordance with
this Section 7.1.

          (c)  Evaluation of Changes.  GWI may request Supplier to evaluate a
               ---------------------                                         
potential revision to the Specifications, and Supplier shall promptly provide to
GWI at no charge a detailed written estimate of all expenses outside the
ordinary course of business that such evaluation will 

                                      48

require.  Upon GWI's approval of the written estimate, Supplier shall proceed
with such evaluation and GWI shall reimburse Supplier for its actual expenses
outside the ordinary course of business involved in such evaluation consistent
with the approved estimate.  GWI shall be obligated to reimburse Supplier for
expenses in excess of the approved estimate only if the basis for the excess
costs is substantiated by Supplier and approved in writing by GWI, which
approval shall not be unreasonably withheld.

          (d)  Certain Expenditures.  If  a revision to Specifications, other
               --------------------                                          
than revisions described in Section 7.1(h) below or Section 7.5 below, requires
Supplier to pay for additional equipment or otherwise pay for costs that, either
on a one-time or an on-going basis, exceed the [*] (including Materials and
Conversion Charges) for that Product projected to be paid to Supplier under this
Agreement pursuant to the most recent applicable forecasts, then GWI shall bear
all necessary and reasonable costs incurred by Supplier directly as a result of
such revision to the Specifications to the extent the same are incurred outside
of Supplier's ordinary course of business. Supplier shall pay all costs
associated with any revisions to Specifications that (i) are described in
Section 7.1(h) below or for which Supplier is responsible pursuant to Section
7.5 below or (ii) GWI is not obligated to bear under this Section 7.1(d).

          (e)  Ownership of Assets.  If GWI bears the costs of changes in

Specifications under Section 7.1(d) for the purchase of capital assets (the "GWI
Assets"), title to such GWI Assets shall be vested in Supplier.  GWI and
Supplier shall determine, however, prior to the installation of GWI Assets at
the Facility whether such GWI Assets are (i) easily removable, in which case GWI
may elect at GWI's expense to remove the GWI Assets from the Facility at the
completion of the

applicable Term, or, if earlier, upon completion of the Transition(s) for each
Product for which the GWI Assets are utilized and, without further obligation to
Supplier, have title to the GWI Assets transferred to GWI; (ii) removable from
the Facility but are either integral to the functioning of certain of Supplier's
assets or would require extensive renovations if removed, in which case at the
earlier of completion of the applicable Term or upon Transition of the relevant
Products for which the GWI Assets are utilized, GWI may, at GWI's expense and
provided it can do so without unreasonably interfering with Supplier's
operations at the Facility, remove the GWI Assets from the Facility and restore
the Facility to a condition comparable (less ordinary wear and tear) to that
existing immediately prior to the installation of such GWI Assets and have title
transferred to GWI, subject to a right of Supplier to acquire the GWI Assets
from GWI at the amount that would have been GWI's depreciated cost on the date
of transfer of title to GWI if GWI had owned the assets; or (iii) are not
practicably removable from the Facility, in which case Supplier shall retain
title to the GWI Assets and have no further obligation to GWI.  During any
period that the GWI Assets are at the Facility, except as otherwise provided in
Section 7.1(d), Supplier shall have all rights and obligations of ownership and
shall be responsible for maintaining, repairing and insuring such GWI Assets as
Supplier, in its reasonable discretion, deems necessary.

          (f)  Development Work. For all changes to the Specifications requested
               ----------------
by GWI, GWI shall, in its discretion, either (x) perform, or arrange for the
performance of, all development work in connection therewith or (y) have
Supplier perform such development work at the Facility. GWI shall reimburse
Supplier for expenses reasonably incurred in connection with such work which are
outside the costs of Supplier's ordinary course of business, except that any
development work required as a result of changes described in Section 7.1(h)
below or the first sentence of Section 7.5 

                                      50

below shall be conducted at Supplier's sole expense.  In the event that Supplier
has insufficient non-financial resources, including equipment, to validate any
revision or to undertake any development activities requested of it, GWI shall
have the right, subject to Section 12.1 below, to employ its own or any third
party's personnel at the Facility in order to conduct such validation

any non-delivery that is directly attributable to a reduction in inventories
below the then applicable inventory planning parameters to the extent required
to meet increased demand in the [*] of a Replenishment Forecast as provided in
Section 8.3(a) above. This penalty shall be in addition to, and not exclusive
of, any remedies which may be otherwise available to GWI pursuant to Section
20.1.

delivery of the certificates of analysis as soon after the Effective Time as
possible, but may, notwithstanding the provisions of Section 9.3(a) above,
substitute certificates of compliance in lieu of the certificates of analysis
required to be delivered pursuant to such Section 9.3(a) above for a period not
to exceed twelve (12) months from the Effective Time in the form attached to
Schedule 9.3(a).  Notwithstanding the foregoing, Supplier shall deliver any

[*] after receipt of such Rejected Quantity by GWI or GWI's designee that
received such Product. GWI's notice of rejection shall state the basis for such
rejection, including any information contained in the certificate of analysis
delivered by Supplier or any testing or inspection results. Failure to so notify
Supplier within such [*] period shall constitute acceptance of any Product

Rejected Quantity meets the Specifications, then samples and/or batch records,
as appropriate, from the batch which is in dispute shall promptly be submitted
for testing and evaluation to an independent third party (including a testing
laboratory) as shall be agreed to in writing by both parties.  The determination
of such third party as to whether the Rejected Quantity meets the Specifications
will be final and binding.  The cost of the testing and evaluation by the third
party shall be borne by Supplier if the third party determines that the Rejected
Quantity in question does not meet the Specifications and by GWI if the third
party determines the Rejected Quantity meets the Specifications.  If any sampled
Rejected Quantity is found by the third party not to conform to the
Specifications, the Rejected Quantity may be handled as provided in Section 9.9
below.

trade name or other designation of origin.  GWI's failure to register or
election not to register any of the Marks shall not be deemed an abandonment or
waiver of any such rights.

          14.2      New Developments and Modifications.
                    ---------------------------------- 

          (a) Supplier Developments.  All Intellectual Property conceived,
              ---------------------                                       
reduced to practice or otherwise developed solely by or on behalf of Supplier in
connection with the Agreement, unless made at the request of GWI pursuant to
Section 14.2(b) below, including any inventions, whether patentable or not,
trade secrets or copyrights ("Supplier Developments") shall be owned by
Supplier.

          (i) As soon as practicable, Supplier shall inform GWI in writing of
any proposal to develop a Supplier Development utilizing or based on any of the
GWI Rights prior to such development, and shall not begin substantial work in
connection therewith without the prior written consent of GWI.  In addition,
Supplier shall inform GWI of any Supplier Development not 

                                      86
<PAGE>
 
utilizing or based on any of the GWI Rights promptly after reduction to practice
of such Supplier Development.  Supplier may not implement or use any Supplier
Development that would require a change to the Specifications without the prior
written consent of GWI, in accordance with Section 7.1(g) above.  Supplier's
failure to give notice required under this Section 14.2(a)(i) will neither (i)
affect Supplier's ownership of any Supplier Development, nor (ii) be deemed to
grant Supplier any rights to use the GWI Rights.

          (ii)  Upon GWI's request, Supplier and GWI shall enter into good faith
negotiations regarding the terms of Supplier's license to GWI of the right to
use and/or exploit a Supplier Development, including royalty terms.  The parties
contemplate that such license terms would provide GWI with the nonexclusive,
nontransferable right to make, have made, use and sell products that practice
such Supplier Development at any location.

          (iii) Supplier will inform GWI in writing of those countries
in which Supplier will file a patent application covering any Supplier
Development prior to filing such patent application.  GWI will have the right
to, at its option:  (a) file a patent application in other countries in
Supplier's name covering such Supplier Development at its own expense, or (b)
require Supplier to file and prosecute patent applications in other countries
covering such Supplier Development at GWI's expense.  All fees and expenses paid
by GWI under this Section 14.2(a)(iii) with regard to patent activities relative
to a particular Supplier Development shall be deducted from any royalties due to
Supplier pursuant to an agreement entered into under Section 14.2(a)(ii) above
with respect to the applicable Supplier Development.  Supplier will use
reasonable efforts to provide GWI with the opportunity to review any publication
by Supplier or any Supplier Affiliate relating to a patentable Supplier
Development prior to such publication, and will upon GWI's request delay 

                                      87
<PAGE>
 
publication for up to 60 days so that a patent application may be filed for such
Supplier Development.

          (b) GWI Developments.  All Intellectual Property conceived, reduced to
              ----------------                                                  
practice or otherwise developed by or on behalf of GWI, including any
developments by Supplier made at the request of GWI pursuant to a further
written agreement, including any inventions, whether patentable or not, any
trademarks, trade dress, trade secrets or copyrights ("GWI Developments") shall
be owned by GWI; provided, it is understood that Supplier shall have no
obligation to conduct any development activities on behalf of GWI.

          14.3      Grant of Licenses.
                    ----------------- 

          (a) By GWI.  Under the terms and subject to the conditions of this
              ------                                                        
Agreement, GWI hereby grants Supplier the non-exclusive, royalty-free  right
during the Term of this Agreement, under the Retained Intellectual Property and
the GWI Developments (collectively, the "GWI Rights") to make, manufacture and
supply Products solely for GWI and solely to perform Supplier's obligations
under this Agreement.  Supplier will have no right or license to make,
manufacture, supply, distribute or sell Products for any other purpose or for or
to any other Person, and, further, Supplier may not use any GWI Rights to make,
manufacture, supply, distribute or sell any products other than the Products.
Except as expressly set forth in this Agreement, GWI shall have no obligation to
provide Supplier with technical information concerning the Products, nor to
otherwise provide technical assistance to Supplier.  All license rights with
respect to each Product granted to Supplier hereunder immediately shall
terminate and revert to GWI upon the termination of the manufacture of such
Product at the Facility pursuant to the terms of this Agreement.  Except on
behalf of GWI, as expressly required under Section 7.4 or conducted pursuant to
Section 14.2(b) of

                                      88
<PAGE>
 
this Agreement, Supplier will have no right or license to use directly or
indirectly the Specifications, any Products or any GWI Rights in connection with
any research and development activities, provided, Supplier may, subject to the
noncompete provision of the Purchase Agreement (Section 7.4 therein) and any
other applicable provisions of this Agreement, use any information within the
GWI Rights obtained independently of this Agreement which enters the public
domain through no breach of this Agreement by Supplier.  GWI reserves all rights
not expressly granted herein.

          (b) Sublicenses.  Solely to the extent: (i) necessary for Supplier to
              -----------                                                      
perform under this Agreement and (ii) that GWI has the right to grant such
sublicense, GWI hereby grants Supplier a non-exclusive, royalty-free sublicense
to make, manufacture and supply Products solely for GWI or any GWI Affiliate
under any and all patent rights, trade secrets, trademarks, know-how and other
proprietary non-patented information owned by a third party which GWI or a GWI
Affiliate has licensed or otherwise has rights to during the Term of this
Agreement ("Sublicense Agreements").  Supplier agrees to comply with all
restrictions and other terms and conditions contained in any agreements or
licenses with third parties of which it is aware relating to the foregoing
rights; provided, GWI and its Affiliates shall be responsible for all payment
obligations due to third parties pursuant to such Sublicense Agreements.  GWI
agrees not to terminate any Sublicense Agreement while Supplier continues to
manufacture and supply Product(s) subject to such a Sublicensed Agreement
pursuant to this Agreement.

          (c) Trademark License.  Subject to the terms and conditions of this
              -----------------                                              
Agreement, GWI grants Supplier during the Term of this Agreement the personal,
nonexclusive and nontransferable license to use the Marks solely in accordance
with the Specifications on and in connection with the packaging, sale, and
distribution of Products as permitted by this Agreement.

                                      89
<PAGE>
 
Supplier shall in no event have any right or license to use any other Marks in
connection with the Products.  The parties acknowledge that Supplier's
obligation to comply with the Specifications is important to preserve the
quality of the products associated with the Marks and GWI's good will associated
with the Marks.  In this connection, Supplier's use of the Marks is expressly
conditioned on compliance with the provisions of Article 9 of this Agreement
regarding testing and quality assurance.  All of the other license limitations
in Section 14.3(a) above shall also apply to the license set forth in this
Section 14.3(c).

                                    06/30/99

          (c) Obligations of Supplier.  Supplier agrees as follows:
              -----------------------                              

          (i) Supplier will use reasonable efforts to ensure that there will be
no failure or production of erroneous results as a result of the inability to
receive, store, process or output date information regardless of the date or
dates utilized, including without limitation related to the change of century in
any computer software, computer hardware, automation systems and devices owned,
licensed or used by Supplier or any suppliers of Supplier (collectively, the
"Computing Devices") that would result in either:  (a) the inability of Supplier
to manufacture and supply Products and supporting documentation and information
under this Agreement, or (b) the failure of defined system interfaces and
connections between Supplier systems and GWI systems (each, a "Failure").

          (ii) Supplier will use reasonable efforts to perform within six (6)
months after the Effective Time such additional testing and assessment of the
Computing Devices not being replaced by Supplier necessary to determine whether
any such Computing Devices may have a Failure as described in Section 15.4(c)(i)
above. Supplier will also, within ninety (90) days after the Effective Time,
prepare a preliminary written plan of action to ensure that the Computing
Devices will not be the subject of a Failure (the "Millennium Compliance Plan").
To the extent

                                      95
<PAGE>
 
reasonably necessary to ensure Supplier's compliance with Section 15.4(c)(i)
above, Supplier will also, within six (6) months after the Effective Time,
contact and use reasonable efforts to determine whether suppliers of goods or
services to Supplier, including without limitation suppliers of computer
software, computer hardware, automation systems and devices, will warrant that
each of the Computing Devices owned, licensed or used by such supplier will not
be the subject of Failures. Supplier will inform GWI in writing of all such
suppliers who will not make such warranties.

          (iii) Supplier shall deliver to GWI a copy of the preliminary
Millennium Compliance Plan not later than ninety (90) days after the Effective
Time, and deliver to GWI a detailed Millennium Compliance Plan within six (6)
months after the Effective Time. Supplier thereafter shall deliver GWI at the
end of each calendar quarter a written report on updates, issues, progress and
changes in schedule, if any, made in relation to the Millennium Compliance Plan.
Supplier shall also use reasonable efforts to implement a plan promptly after
the Effective Time the goal of which is to prevent the purchase or license of
Computing Devices that may be the subject of Failures. Supplier shall notify GWI
in writing and provide GWI with details promptly in the event that Supplier
obtains: (a) information (other than information already included in the Year
2000 report prepared by Data Dimension, Inc. for GWI prior to the Effective Time
(the "DDI Report")) that any Computing Devices owned, licensed or used by
Supplier may be the subject of a Failure, or (b) any material supplements,
modifications or clarifications of the DDI Report. Supplier shall also notify
GWI in the event Supplier becomes aware that any computer software or systems
owned, licensed or used by GWI and related to the Facility may be the subject of
a Failure. Upon GWI's written request, Supplier agrees to participate at GWI's
expense in additional tests to be conducted

securities, on a fully diluted basis, of either Supplier or Parent or (ii) any
proposed transaction involving the acquisition by any party on or before June
30, 2000 of more than 50% of the voting securities, on a fully diluted basis, of
either Supplier or Parent, other than any transaction permitted by Section
25.6(b) below (either, a "Proposed Change in Control Transaction"), which shall
not include the issuance of Class A and Class B Common Stock by Parent as of the
Effective Time.  Notwithstanding the foregoing, if neither Supplier nor Parent
knows or has reason to know of a Proposed Change in Control Transaction at least
ninety (90) days prior thereto, then Supplier or Parent shall notify GWI of the
Proposed Change in Control Transaction promptly upon Supplier or Parent learning
of, or having reason to know of, the Proposed Change in Control Transaction.
For 

                                      121

a period of sixty (60) days after receipt of a written notice from Supplier or
Parent of a Proposed Change in Control Transaction, GWI may elect to terminate
this Agreement by providing written notice to Supplier of such election, and any
such termination shall be effective not less than six (6) months from the date
of the GWI notice of election to terminate. Failure of GWI to notify Supplier of
its election to terminate within sixty (60) days of receipt of a written notice
from Supplier or Parent of a Proposed Change in Control Transaction will be
deemed a waiver by GWI of its right to terminate, but GWI's right to terminate
this Agreement with respect to a given Proposed Change in Control Transaction
shall be reinstated, if Supplier or Parent provides GWI with a written notice of
a Proposed Change in Control Transaction, and such Proposed Change in Control
Transaction is not consummated within 180 days of delivery of such notice by
Supplier or Parent.

          20.9      No Suspension of Obligations.  Notwithstanding anything to
                    ----------------------------                              
the contrary herein, if any dispute arises between the parties, in no event nor
for any reason (i) shall Supplier interrupt, slow down or reduce in any way the
manufacturing, packaging, testing, delivery, supply or Transition of Products,
unless authority to do so has been granted by GWI or specifically conferred by a
court of competent jurisdiction or (ii) shall GWI fail to make any payment when
due to Supplier unless specifically permitted by a court of competent
jurisdiction or the portion of any payment hereunder which is the subject of a
pending dispute identified by GWI in a written notice delivered to Supplier
following receipt of an invoice or other demand for payment made hereunder
stating the amount and basis of GWI's good faith objection or challenge pursuant
to Sections 5.1(c), 5.2(d), 5.3(a), 6.3(b), 7.1(c), 7.1(d), 8.1(c), 9.10, 9.12
or 15.4(b) of this Agreement.

          20.10     Remedies.  Except as expressly set forth in this Agreement,
                    --------                                                   
none of the remedies set forth in this Agreement are intended to be exclusive,
and each party shall have available 

                                      122
<PAGE>
 
to it all remedies available under law or in equity.  The parties specifically
acknowledge and agree that GWI will have available the remedy of specific
performance under this Agreement upon a Supplier Material Default.

          20.11     Injunctive Relief.  In the event that Supplier breaches or
                    -----------------                                         
threatens to breach any provision of Article XXII of this Agreement, irreparable
harm to GWI should be presumed and the damage to GWI would probably be very
difficult to ascertain and would be inadequate. Accordingly, in the event of
such circumstances, Supplier agrees that, in addition to any other right and
remedies available at law or in equity, GWI shall have the right to obtain
injunctive relief from any court of competent jurisdiction.

                                  ARTICLE XXI

                         LIABILITY AND INDEMNIFICATION

          21.1      Indemnity by Supplier.  Subject to the limitation set forth
                    ---------------------                                      
in Section 9.9, with respect to Rejected Quantities not distributed to third
parties and the provisions of Section 21.5 below, Supplier shall indemnify,
defend and hold GWI and each GWI Affiliate who receives a Product subject to
indemnity hereunder and their respective directors, officers, employees and
agents (each a "GWI Indemnitee") harmless from and against all Losses arising
from, based upon or caused by the failure of any Products to conform to the
Specifications prior to placement with the carrier, or Supplier's (a) negligence
or willful misconduct, including any such negligence or willful misconduct which
results in an event described in Section 9.6  (in which case the Losses of GWI
to be indemnified by Supplier, subject to Section 9.7(d), may also include the
price paid by GWI to Supplier for such an affected Product and all costs
incurred by GWI in connection therewith, 

                                      123

Requirements, the Environmental Laws or the FD&C Act, (c) material breach of any
of Supplier's covenants, obligations, representations or warranties under this
Agreement or(d) destruction of any Product by Supplier in accordance with the
terms of this Agreement. The foregoing indemnification obligations shall not
apply in each case to the extent any particular Loss is a direct result of (i)
the negligence or intentional misconduct of a GWI Indemnitee; (ii) a breach by
GWI of a representation or covenant hereunder or under the Purchase Agreement;
(iii) any failure by GWI to comply with the FD&C Act or the provisions of

Specifications or an order of a Governmental Body directed to Supplier
specifically regarding its compliance with CGMPs, the FD&C Act, Environmental

Supplier hereunder, such Products (a) have been altered or adulterated, (b) have
not been maintained in accordance with CGMP, applicable transportation, storage,
handling or maintenance requirements, (c) have been damaged by negligence or
accident or (d) have been damaged by acts of nature, vandalism, burglary,
neglect or misuse other than by Supplier or its representatives. Nothing in this
Section 21.1 or Section 21.3 below shall be construed to limit, and these
provisions shall be in addition to, any indemnification provision in the
Purchase Agreement and any other agreement between the parties.

To the extent any breach of a representation and warranty hereunder constitutes
a breach of a representation and warranty under the Purchase Agreement, then the
indemnified party's exclusive 

                                      124
<PAGE>
 
remedy with respect to such breach shall be to seek indemnification pursuant to
the provisions of the Purchase Agreement.

          21.2      Indemnity by GWI.  Subject to Section 21.5 below, GWI shall
                    ----------------                                           
indemnify, defend and hold Supplier and the Supplier Affiliates and their
respective directors, officers, employees and agents (each a "Supplier
Indemnitee") harmless from and against all Losses not otherwise reimbursed by
GWI to Supplier arising from, based upon or caused by (a) the distribution or
marketing of Products by GWI or any GWI Affiliate acquiring Product directly or
indirectly pursuant to this Agreement and/or the administration or use thereof,
(b) GWI's failure to obtain, maintain or comply in any respect with any of its
Consents which are required to perform any of its obligations hereunder, or

FD&C Act, (c) material breach of any of GWI's covenants, obligations,
representations or warranties under this Agreement or the Deed of Easement or
GWI's representations, warranties, covenants or obligations under the Purchase
Agreement, (d) Supplier's compliance with the Specifications or use of any Key
Ingredients provided Supplier complies with the provisions of this Agreement
relating to testing of such Key Ingredients and could not have reasonably
discovered the defects contributing to such Loss, (e) destruction of any Product
by GWI in accordance with the terms of this Agreement or (f) any claim that the
practice of the Licensed Technology by Supplier, or the manufacture, use or sale
of the Materials or Products constitutes trade secret misappropriation or
infringes the intellectual property rights of any third party. The foregoing
indemnification obligations shall not apply in each case to the extent any
particular Loss is a direct result of the negligence or intentional misconduct
of a Supplier Indemnitee or for which Supplier is obligated to indemnify GWI
pursuant to Section 21.1 above. Nothing in this Section 21.2 or Section 21.3
below

                                      125
<PAGE>
 
shall be construed to limit, and these provisions shall be in addition to, any
indemnification provision in the Purchase Agreement and any other agreement
between the parties. To the extent any breach of a representation and warranty
hereunder constitutes a breach of a representation and warranty under the
Purchase Agreement, then the indemnified party's exclusive remedy with respect
to such breach shall be to seek indemnification pursuant to the provisions of
the Purchase Agreement.

          21.3      Environmental Indemnity.  Without limiting the generality of
                    -----------------------                                     
Section 21.1 above or any other obligation of Supplier under any other agreement
between Supplier and GWI, Supplier shall indemnify, defend and hold GWI and each
GWI Affiliate harmless from and against Environmental Losses as provided in, and
subject to the limitations of, Section 8.2 and Article XII of the Purchase
Agreement.  GWI shall indemnify, defend and hold Supplier and each Supplier
Affiliate harmless from and against Environmental Losses to the extent such
Environmental Losses arise from acts under GWI's control during any period in
which GWI occupies a portion of the Facility under the provisions of Section
20.5 hereunder and the terms of Exhibit G hereto.

          21.4      Procedures.  Any indemnification of GWI, GWI Affiliates,
                    ----------                                              
Supplier or Supplier Affiliates hereunder shall include and extend to the
benefit of their respective shareholders, directors, officers and employees.
Any person that may be entitled to indemnification under this Agreement (an
"Indemnified Party") shall give written notice to the Person obligated to
indemnify it (an "Indemnifying Party") with reasonable promptness upon becoming
aware of any claim or other facts upon which a claim for indemnification will be
based; the notice shall set forth such information with respect thereto as is
then reasonably available to the Indemnified Party.  The Indemnifying Party
shall have the right to undertake the defense of any such claim asserted by a
third party with counsel reasonably satisfactory to the Indemnified Party and
the Indemnified Party shall 

                                      126
<PAGE>
 
cooperate in such defense and make available all records, materials and
witnesses reasonably requested by the Indemnifying Party in connection therewith
at the Indemnifying Party's expense.  If the Indemnifying Party shall have
assumed the defense of the claim with counsel reasonably satisfactory to the
Indemnified Party, the Indemnifying Party shall not be liable to the Indemnified
Party for any legal or other expenses (other than for reasonable costs of
investigation) subsequently incurred by the Indemnified Party in connection with
the defense thereof.  The Indemnifying Party shall not be liable for any claim
settled without its consent, which consent shall not be unreasonably withheld or
delayed.  The Indemnifying Party shall obtain the written consent of the
Indemnified Party prior to ceasing to defend, settling or otherwise disposing of
any claim if as a result thereof the Indemnified Party would become subject to
injunctive or other equitable relief or if the Indemnified Party may reasonably
object to such disposition of such claim based on a continuing adverse effect on
the Indemnified Party.

          21.5      Limitations.  In no event shall either party be liable to
                    -----------                                              
the other, or have any obligation to indemnify any GWI Indemnitee, or Supplier
Indemnitee, as the case may be, for any consequential or indirect damages or
Losses including any loss of profits suffered by GWI or Supplier, however caused
and on any theory of liability.  This limitation shall apply notwithstanding any
failure of essential purpose of any remedy available under this Agreement. The 
foregoing limitation on liability shall not be applicable to lost profits 
incurred by GWI as a direct result of any failure by Supplier to timely ship 
Products to GWI which would be a Supplier Material Default pursuant to Section 
20.1(b) which GWI can demonstrate is due to willful misconduct by Supplier taken
in bad faith with the intent to manufacture products for a third party with the 
knowledge that as a direct result Supplier will be unable to timely ship 
Products to GWI as provided by the terms


                                      127
<PAGE>
 
of this Agreement; provided, in no event should Supplier's liability for lost 
profits under this Section exceed $50 million. GWI shall inform Supplier in
writing of its intent to seek damages pursuant to the foregoing sentence and
provide Supplier with a reasonable opportunity to remediate any such Loss;
provided, that nothing in this sentence shall relieve Supplier of its
obligations to supply and manufacture Products in accordance with the terms of
this Agreement. For the avoidance of doubt, it is understood and agreed that
Supplier's business is dynamic and evolving based on market demand, regulatory
approvals and other factors, and Supplier has the right and authority to conduct
its business as it deems appropriate, and shall have no obligations or
liabilities under this Section 21.5 except as expressly provided above.

only for the purpose of performing under this Agreement.

          (b) Permitted Exceptions.  Each party may disclose the other party's

Confidential Information and will require such Representative to agree in

of each such requirement and identify the documents so required thereby, so that
the other party may seek an appropriate protective order or other remedy and/or
waive compliance by the first party with the provisions of this Article XXII,
(ii) consult with the other party on the advisability of taking legally
available steps to resist or narrow the scope of such requirement, (iii) assist
the other party in seeking a protective order or equivalent, and (iv) comply

otherwise make any public statement or advertisement with respect to this
Agreement, any of the Products, or the transactions contemplated hereby without
the prior written consent of GWI, and GWI will not issue any press release or
otherwise make any public statement with respect to this Agreement or that
refers directly or indirectly to Supplier as a manufacturer of the Products
without the prior written consent of Supplier, provided, however, that either
party shall be entitled to make a public announcement of this Agreement after
giving prior written notice to the other party hereto, if, in the opinion of the
disclosing party's legal counsel, such announcement is required to comply with
 
                                      132

applicable laws and provided to the extent practicable the other party has
received at least two (2) days' notice. Once consent is given by GWI for a
required disclosure in a filing made with the Securities and Exchange
Commission, Supplier may make additional disclosures in other filings made with
the Securities and Exchange Commission that do not materially differ therefrom
without any further consents, provided that the surrounding circumstances have
not changed.

          22.7      Return of Confidential Information.  At any time upon the
                    ----------------------------------                       
request of the other party, to the extent such Confidential Information is not
reasonably necessary to enable a party to perform its obligations under this
Agreement, the receiving party shall promptly return to the other party or
destroy the other party's Confidential Information, and shall destroy all copies
thereof, together with all notes, drawings, abstracts and other information
relating to the other party's Confidential Information prepared by the receiving

information is stored; provided, however, that the receiving party may maintain
a single archival copy of the other party's Confidential Information in its
files for purposes of establishing the extent of disclosures by the other party
under this Agreement.  At either party's written request, such party's
Confidential Information that is otherwise required to be returned to it shall
be destroyed by the receiving party and such destruction shall be certified in
writing by an authorized officer of the receiving party.  The return and/or
destruction of such Confidential Information as provided above shall not relieve
the receiving party of its other obligations under this Article XXII. In the

                                 FORCE MAJEURE

          24.1      Force Majeure Event.  Neither party shall be liable to the
                    -------------------                                       
other on account of any failure to perform or on account of any delay in
performance of any obligation under this Agreement, if and to the extent that
such failure or delay shall be due to a cause beyond the control of the relevant
party and which, by the exercise of its commercially reasonable efforts of
diligence and care, such party could not reasonably have been expected to avoid
(a "Force Majeure Event").  The party affected shall promptly notify in writing
the non-affected party of the specific causes beyond the control of that party
and the probable duration of the delay and be excused from such performance of
such obligation to the extent that it is necessarily prevented, hindered or
delayed thereby during the continuance of any such happening or event.  This
Agreement, in so far as it relates to such obligation, shall be deemed suspended
so long as and to the extent that such cause delays the performance of any Force
Majeure Event obligation.

          24.2      Extended Force Majeure Event.  Notwithstanding Section 24.1
                    ----------------------------                               
above, (i) in the event that Supplier is unable to supply for any period of [*]
of the then applicable Binding Primary Commitment because of any Force Majeure
Event, GWI may, upon written notice to Supplier, terminate this Agreement; (ii)
in the event that Supplier is unable to

                                      135

supply any Products for any period of [*] due to such Force Majeure Event, GWI
may, upon written notice to Supplier, effect a Transition with respect to such
Product(s); or (iii) in the event of either clause (i) or (ii) occurring, GWI
may agree to and implement a recovery plan with respect to Supplier's
obligations for supplying such Product in a manner that ensures continuity of
supply. Part of any such recovery plan may include, if GWI so elects, temporary
relocation of the manufacture of such Product to an Outside Facility. In the
event that Supplier fails to perform under any recovery plan, GWI shall have the
right, in addition to any of its other rights hereunder, upon notice to Supplier
immediately to manufacture such Product or have such Product manufactured by a
third party supplier at an Outside Facility or pursuant to an arrangement
substantially similar to that described in Section 20.5 above until Supplier is
able to resume the manufacture and supply of such Product. Supplier shall
promptly cooperate with and provide all necessary technical assistance to GWI,
in effecting any manufacture of any Product at another facility as if it were a
Transition of such Product. The expenses of such assistance shall be borne by
Supplier if the affected Products are being permanently Transitioned out of the
Facility and shall be shared equally by the parties if the transition is
temporary.

          24.3      Tolling of Certain Obligations.  During the continuance of
                    ------------------------------                            
any Force Majeure Event, the Guaranteed Revenues payable by GWI under Article VI
shall be reduced by the amount of the Conversion Charges for the affected
Products contained in the relevant Binding Product Commitment and relevant
forecast.

contemporaneous agreements and understandings between the parties with respect

allegedly in breach of the applicable restrictions after the Effective Time,

Specifications, Products, GWI Rights and other information. However, despite
these efforts, the parties acknowledge the possibility of involuntary or
inadvertent omissions from the Schedules. The parties will agree in writing to
the changes to be made to the Schedules to add these inadvertent or involuntary
omissions and any such written agreement executed by the parties shall serve as
an amendment to this Agreement.

delegated or otherwise disposed of by Supplier without the prior written consent
of GWI (which consent may be given or withheld by GWI in it sole discretion),
including any assignment by operation of law or as a result of a Proposed Change
in Control Transaction, provided, however, that (i) Supplier or Supplier's
primary lenders or lending syndicate or the agent for such lenders or syndicate
(for purposes of this Section 25.6(a), the "Lenders") may assign this Agreement
pursuant to a Proposed Change in Control Transaction with respect to which
Supplier has complied with the provisions of Section 20.8 above, (ii) Supplier
may assign to the Lenders Supplier's right to payments and to enforce payments
due from GWI under this Agreement and the Deed of Easement in the form attached
as Exhibit G, and (iii) Supplier may assign as collateral to the
   ---------           
Lenders Supplier's interests under this Agreement and the Deed of Easement in
the form attached hereto as Exhibit G, provided that any such collateral
                            --------- 
assignment shall expressly provide that (A) the Lenders' rights to foreclose
upon or otherwise dispose of Supplier's interests in this Agreement will be
subject to the condition that such foreclosure or disposition occur in
connection with a foreclosure or sale in lieu of foreclosure of the Lenders'
security interests in the Facility and/or the capital stock of Supplier and/or
Parent, (B) the Lenders shall not be entitled to exercise any remedy with
respect to this Agreement other than (x) a foreclosure sale and assignment of
this Agreement to a Permitted Transferee subject to and upon the terms contained
in Section 25.6(b) of this Agreement, (y) to enforce rights to payment as
provided in clause (a) (ii) above and (z) upon the occurrence and during the
continuance of an event of default as defined in the applicable security
agreement or other instrument or agreement pursuant to or in connection with
which such collateral assignment shall have been made, the right to demand that

Agreement must also acquire the Facility and/or the capital stock of Supplier
and/or Parent, (D) in no event shall the Lenders be entitled to assume, perform,
satisfy or discharge any of Supplier's obligations other than with respect to
payment of money or issuance of credits to GWI due by Supplier under this
Agreement, (E) the provisions described in this Section 25.6 (a) shall not be
amended without the prior written consent of GWI, which consent (in the case of
amendments as to form, but not as to substance) shall not be unreasonably
withheld and (F) GWI is a third-party beneficiary of such provisions with full
rights at law and in equity to enforce the same. GWI and each GWI Affiliate may
assign its rights (but not its obligations) under this Agreement to any GWI
Affiliate. This Agreement shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and permitted assigns. Except as
otherwise expressly provided herein, none of the provisions of this Agreement is
intended to grant any right or benefit to any person or entity other than GWI,
the GWI Affiliates, Supplier, the Supplier Affiliates, Parent or the GWI
Affiliates.

          (b) This Agreement may be assigned to a "Permitted Transferee" as
defined below in connection with a foreclosure or sale in lieu of foreclosure of
any security interests in (i) the Facility and/or (ii) the capital stock of
Supplier and/or Parent by Supplier's primary lender(s) or lending syndicate or
the agent for such lenders or syndicate (collectively the "Foreclosing Party").
GWI acknowledges and agrees that any action of the Foreclosing Party in
foreclosing on a pledge of the capital stock of Parent or Supplier and any sale
(including any sale in lieu of foreclosure) of such capital stock to a Permitted
Transferee shall not be subject to the provisions of Section 20.8 hereof.  The
parties acknowledge that notwithstanding anything in this Agreement to the 
contrary

                                      142
<PAGE>
 
the provisions of this Section 25.6(b) may be enforced by, and shall be deemed
for the benefit of, the Foreclosing Party.

          As used herein, "Permitted Transferee" shall mean only a Person who:

          (i) shall agree in writing to assume Supplier's obligations under this
Agreement and to be bound by all the terms and provisions of this Agreement;

          (ii) is not at the time of the assignment of this Agreement engaged,

          (iii) is experienced in or has, or will have as a condition to such

noncompetition agreement on the terms provided in Section 7.4 of the Purchase
Agreement;

          (vi) is in good standing with the FDA and has for the five (5) year
period prior to the assignment of this Agreement a satisfactory record of

agencies or divisions thereof as (demonstrated to the reasonable satisfaction of

                                      143

GWI), except to the extent any noncompliance would not reasonably be expected to
have a material adverse effect on the ability of such Permitted Transferee to
operate a pharmaceutical manufacturing facility of the type described in (iii)
above; and

          (vii) is not, and has no affiliate that is, at the time of assignment
or during any time within the two (2) year period prior thereto has been engaged
in any litigation or arbitration involving GWI or any GWI Affiliate involving
claims, or Products with annual revenues, in excess of at least [*]

          In the event that the Foreclosing Party desires to sell the Facility
and/or the stock of Parent and/or Supplier in connection with an exercise of the
Foreclosing Party's rights under security interests therein and in this
Agreement to the extent permitted under Section 25.6(a), the Foreclosing Party
shall make a proposal to GWI for the sale thereof at a specified price (the
"Proposal"). The Foreclosing Party shall provide GWI with a period within which
to elect to purchase the Facility or stock at the price and on the terms
contained in the Proposal, which period shall end no earlier than [*] from the
date of delivery of the Proposal if the Proposal is made prior to a foreclosure

Party has provided GWI with notice at [*] delivery of the Proposal of the
Foreclosing Party's intent to effect a foreclosure or sale in lieu of
foreclosure. In no event may the Foreclosing Party sell less than the entire
Facility; provided, the Foreclosing Party may sell either (i) the Steriles
Facility on a stand alone basis or (ii) the combination of the Primary Facility
and the Secondary Facility on a stand alone basis, in each case if (x) the
transferee has received all Consents that would be required to operate the 
Steriles Facility and (y) the sale would not be reasonably expected to result in

elect but fails, within [*] from the date of such election, to effect the
purchase, the Foreclosing Party may sell the Facility, and/or stock at a price
equal to or higher than that contained in the Proposal and on terms no more
favorable to the buyer within [*] after (i) the deadline for GWI to respond to
the Proposal or (ii) if GWI accepts the Proposal but fails to effect the
purchase [*] after its acceptance of the Proposal, after the end of such [*]
(such 12-month period, the "Sale Period"). The Foreclosing Party must repeat the
procedures set forth above prior to any sale at a lower price or on terms more
favorable to the buyer after the Sale Period.

          25.7      Amendment.  Any amendment, modification or supplement of or
                    ---------

Agreement to be invalid or unenforceable, such holding shall in no way affect
the validity or enforceability of the remainder of this Agreement, and the
invalid or unenforceable provision shall be fully severed from this Agreement
and there shall automatically be added in lieu thereof a provision as similar in
terms and intent to such severed provision as may be legal, valid and
enforceable.
