7.4 The Parties shall establish a Manufacturing Committee with two
representatives of each Party and with such other committee
members as may reasonably be required from time to time. The
Manufacturing Committee shall liaise as may be agreed from
time to time in connection with;

7.4.1 The supply of API and finished Product to Shire
during the Supply Period under Clause 10;

{PAGE}

7.5 The Manufacturing Committee shall meet alternately in London
and in Palo Alto, California unless otherwise agreed and shall
liaise by telephone and other communication as reasonably
required from time to time by either Party. It is proposed
that the initial members of the Manufacturing Committee shall
be:

Shire: Rob Haslam, Jenny Fox

Glycyx: John Brough, Randy Hamilton

Each Party shall use reasonable endeavours to maintain
effective membership of the Manufacturing Committee and, if a
person shall cease to be a member of the Manufacturing
Committee, shall replace him with a suitably qualified
replacement. The Parties shall at all times have an equal
number of representatives on the Manufacturing Committee.

7.6 It is the intention of the Parties that all matters relating
to the further development of the Product and the manufacture
of API and the Product during the Supply Period and thereafter
shall be discussed in good faith and considered by the
Development Committee or the Manufacturing Committee as may be
agreed between the Parties from time to time. Without in any
way limiting the obligations of Glycyx in respect of the
transfer of the Product Registrations to Shire, Shire may
refer matters concerning the detailed arrangements for such
transfer to the Development Committee. Decisions of the
Development Committee and the Manufacturing Committee shall be
valid only if unanimously agreed by the two representatives of
each Party on the committee.

7.7 In the event that either the Development Committee or the
Manufacturing Committee are unable to reach agreement on any
particular issue, either committee may refer the matter for
determination by the Chief Executive Officers of each Party
("CEOs"). In the event of any such referral each Party shall
prepare and submit to the CEOs a memorandum or statement
setting out its position in respect of the matter in dispute
and its reasons for adopting that position and the CEOs shall
consider the dispute in the light of those statements. If the
CEOs agree upon the resolution of the dispute they shall issue
a joint statement setting out the agreed terms and shall
exercise all powers available to them to procure that the
agreed


17
{PAGE}

terms are fully and promptly carried into effect by the
relevant committee and the Parties.

7.8 If the matter is not resolved or disposed of in accordance
with Clause 7.7 the matter shall be referred to an independent
expert (experienced in the manufacture of pharmaceuticals or
the development of pharmaceutical products, as appropriate who
shall act as an expert and not an arbitrator) appointed by the
agreement of the Parties, or in the event that the Parties are
unable to agree on the independent expert, such expert shall
be appointed at the request of either Party by the President
for the time being of the Royal Pharmaceutical Society of
Great Britain who shall have the authority to appoint such an
expert.

Shire and Glycyx (or their Affiliates, Sublicensees or
sublicensees) sufficient to satisfy the demand for API and/or

10.10.3 in respect of the [*] within their respective
markets at the date of any such shortage of supply.

10.11 Shire undertakes to use all reasonable commercial endeavours

price. Shire will use reasonable commercial endeavours to
procure that [*] in respect of its premises at [*] and at [*]

impact on the Transfer Date. Notwithstanding that Shire shall
order and obtain API from Third Party Contractors direct on
its own account during the Supply Period, the Parties shall
make such payments as shall ensure that the price borne by
Shire for all quantities of API delivered to Shire during the
Supply Period (up to a maximum aggregate total of [*] [(*)]
tonnes (the "Maximum Quantity")) shall be (pound)[*]p ([*]

(thirty) days of each of 31 December 2000 and 31 December
2001, the Parties shall review the total aggregate quantity
of API delivered to Shire, the price paid by Shire for such
quantity and upon review in December 2001, sums paid by
either Party on the December 2000 reconciliation and upon such
review shall effect such payment taking account of the
aggregate total to the date of the reconciliation and any sums
paid on the previous reconciliation, as may be required to
procure that the price borne by Shire for API shall be the
Price. Any such payment shall be made by Shire to Glycyx in
the event that the actual price paid shall be less than the
Price and shall be made by Glycyx to Shire in the event that
the actual price paid shall be greater than the Price.

10.12 Shire shall not enter into any contract with any Third Party
Contractor for the supply of API during the Supply Period
without the prior approval of Glycyx (such approval not to be
unreasonably withheld or delayed subject to Glycyx being
satisfied as to the price of supply and the availability of
supply to meet the demand of both Glycyx and Shire for API
during the Supply Period). In the event that Shire proposes to
obtain its supplies of API during the Supply Period from a
Third Party at a price different from the Price it shall
notify Glycyx and if the price exceeds the Price Shire will
give Glycyx the opportunity to obtain the supply to Shire of
the quantities required to be delivered in the Supply Period
(up to the Maximum Quantity) from such Third Party Contractor
or Third Party as Glycyx may designate.
