         2.1 Appointment as Distributor. Subject to the terms and conditions of
this Agreement, Orphan Medical hereby appoints Celltech, and Celltech accepts
such appointment, as Orphan Medical's exclusive distributor of the Product in
the Territory. During the Term of this Agreement, Celltech shall purchase all of
its requirements of the Product from Orphan Medical as the sole supplier except
as follows:

                  (a) Celltech Manufacturing. Orphan Medical agrees to discuss
with Celltech the feasibility and commercial viability of transferring the
manufacture of the Product to Celltech's FDA approved facilities or qualifying
and registering Celltech as a back-up manufacturer for the Product for the
Territory and/or for the rest of the world.

                  (b) Third Party Manufacturing. If Orphan Medical is unable to
manufacture or supply the quantity of Product ordered by Celltech in accordance
with this Agreement for any reason whatsoever, including, without limitation, by
reason of an event described in Section 16.1 (Events of Force Majeure), Celltech
shall have the right at its sole election to (A) take over the manufacture of
the Product or appoint a Third Party manufacturer to fulfill Orphan Medical's
manufacturing and supply obligations under this Agreement thereafter through the
remaining Term of this Agreement and/or (B) purchase the API from Orphan Medical
and itself convert, or appoint a Third Party manufacturer to convert, the API
into Product through the Term of the Agreement; provided, however, such right
shall be exercisable only if (1) Orphan Medical's inability to manufacture or
supply the Product could reasonably be expected to result in a period of time of
at least three (3) months during which less than fifty percent (50%) of Product
ordered pursuant to Celltech's last firm purchase order would be available to
Celltech for commercial sale, (2) Celltech provides reasonable evidence of its
ability to procure a Third Party manufacturer or take over the manufacture of
the Product or the API more rapidly than Orphan Medical could restart production
and supply of Product, and (3) Orphan Medical's inability to manufacture or
supply Product did not result, wholly or in part, from a breach by Celltech of
its obligations hereunder. Orphan Medical shall provide Celltech with all
reasonable assistance in taking over or obtaining and qualifying a Third Party
manufacturer, including without limitation, licensing its Manufacturing Know-How
to Celltech and/or such Third Party manufacturer solely for the purpose of
manufacturing the API and/or the Product pursuant to this Section 2.1(b).

                  (c) Price for Manufacturing Changes. In the event Celltech
shall manufacture Product or API or cause Product or API to be manufactured
pursuant to this Agreement, a manufacturing royalty, transfer price or price of
manufacturing services to Orphan Medical, and any other related terms therefor,
shall be negotiated in good faith.

                  (d) Component Sourcing. Celltech shall be permitted at any
time during the Term on sixty (60) days prior written notice to Orphan Medical
to cease purchasing some or all Components from Orphan Medical and purchase some
or all of the Components directly from


                                       6
<PAGE>


Orphan Medical's suppliers or qualify another Third Party(ies) to supply
Components; provided that, subject to Sections 7.7 and 7.12, Celltech must
purchase all Components delivered by Orphan Medical pursuant to a firm order
regardless of whether such delivery is made after Celltech delivers notice to
Orphan Medical of its intent to purchase the Components from Orphan Medical's
suppliers or another Third Party(ies). Celltech shall bear any and all costs
associated with qualifying any Third Party(ies) to supply Components pursuant to
this Section 2.1(d); provided that if Orphan Medical desires to purchase the
same Components from such Third Party(ies) as Celltech is purchasing, then
Orphan Medical and Celltech shall each bear fifty percent (50%) of any such
costs.

         2.2 License Grant. Subject to the terms and conditions of this
Agreement, Orphan Medical hereby grants Celltech an exclusive nontransferable,
royalty-bearing right and license (with the right of sublicense, as specifically
set forth herein), to use the NDA, Know How, Trademark, Patent Rights and all
Improvements and Proprietary Information of Orphan Medical related thereto or to
the Product together with the goodwill associated therewith (the "LICENSED
INTELLECTUAL PROPERTY") during the Term, solely in the Territory, and solely for
the purposes of (i) preparing applications for Marketing Authorizations and
obtaining and maintaining Registrations and packaging, labeling, promoting,
marketing, selling and distributing the Product under the Trademark in the
Territory solely for the Licensed Indications and (ii) exercising its other
rights under this Agreement including those provided in Articles X and XI hereof
and making or having made API and/or Product but only as provided in Section
2.1. Except as set forth in Section 6.8, no license is granted to Celltech
hereunder for any rights to market the Product for other Indications. Except as
provided in Section 14.6, the license set forth above shall terminate
automatically upon termination or expiration of this Agreement. Subject only to
the foregoing express license grant and its other rights as herein provided,
Celltech shall not have and shall not assert any claim, right, title or interest
in or to the Licensed Intellectual Property.

         2.3 Right of First Negotiation for Other Indications.

                  (a) Negotiation Notice. If, during the Term of this Agreement,
Orphan Medical desires to pursue further development of the Product in the
Territory for one or more Indications other than the Licensed Indications, or in
the Option Countries or in Australia for the Licensed Indications or one or more
Indications other than the Licensed Indications, Orphan Medical shall provide
written notice to Celltech (the "NEGOTIATION NOTICE") of its intent to negotiate
an agreement therefor. The Negotiation Notice shall identify the relevant
country or countries and Indications. Delivery of a Negotiation Notice shall
create a mutual obligation to negotiate in good faith on an exclusive basis for
the grant to Celltech of exclusive rights to the Product for the specified
countries for such Indication(s). If no response is received within ninety (90)
days after delivery of the Negotiation Notice to Celltech, the offer shall be
deemed declined, and Orphan Medical may then negotiate with any Third Party for
the grant of any license for the Product for such countries for such
Indication(s) subject, however, to the last sentence of Section 2.3(b).

                  (b) Procedure of Negotiations. The parties shall have ninety
(90) days from the date Orphan Medical receives Celltech's response to the
Negotiation Notice to negotiate in good faith (and on a confidential basis), and
enter into a letter of intent, term sheet or final agreement with regard to, as
applicable, Celltech's distribution of the Product in the Territory for


                                       7
<PAGE>


the new Indication(s) or in the Option Countries or Australia for the Licensed
Indications or one or more Indications other than the Licensed Indications. In
the event that (i) Celltech shall have failed to have responded to the
Negotiation Notice within the 90-day period provided in paragraph (a) above or
(ii) within the 90-day period provided in this paragraph (b) Orphan Medical and
Celltech have not entered into such letter of intent, term sheet or final
agreement, Orphan Medical shall have no further obligation to undertake or
continue negotiations with Celltech for such license, and Orphan Medical shall
be free to commence negotiations for a license to the Product for such countries
for such Indication(s) with any Third Party subject to the following: (i) if a
letter of intent, term sheet or final agreement with a Third Party shall not
have been signed by Orphan Medical and such Third Party within two hundred
seventy (270) days of the termination of Celltech's right of first negotiation,
then Celltech's right of first negotiation shall again become effective on the
terms herein provided and (ii) without Celltech's prior written consent, the
terms and conditions agreed by Orphan Medical with such Third Party may not be
in the aggregate materially more favorable to such Third Party than those last
offered to Celltech.

                  (c) Option Countries. If Orphan Medical shall determine to
enter into a license for the Product with a Third Party in an Option Country
upon expiration of Celltech's right of first negotiation pursuant to Section
2.3(b) above, such license shall contain a provision automatically terminating
such License should such country subsequently join the European Union or
European Free Trade Area during the Term and Celltech shall have exercised its
Option under Section 2.6 as to such country.

                  (d) No Trademark License. If pursuant to this Section 2.3
Orphan Medical licenses to a Third Party the Product in the Territory for one or
more Indications other than the Licensed Indications or in the Option Countries
or Australia for one or more Indications other than the Licensed Indications,
then such Third Party shall be obligated to market the Product under a trademark
different from the Product Trademark and Orphan Medical shall not grant, license
or otherwise transfer to such Third Party any rights to the Trademark or
otherwise permit any use of the Trademark by such Third Party.

         2.4 Subdistributors/Sublicensees. Celltech may appoint Subdistributors
and Sublicensees with the prior written approval of Orphan Medical, which
approval shall not be unreasonably withheld. No such appointment or delegation
shall relieve Celltech from any obligations hereunder, and each agreement with a
Subdistributor or Sublicensee shall include terms ensuring the protection of
Orphan Medical's rights under this Agreement. Celltech shall guarantee and be
responsible for the making of all payments due, and the making of reports
required under this Agreement by its Subdistributors and Sublicensees, and their
compliance with all applicable terms of this Agreement. All agreements between
Celltech and its Subdistributors and Sublicensees shall include a provision
prohibiting the further appointment of Subdistributors or Sublicensees, as the
case may be, and a provision terminating the Subdistributor or Sublicensee
agreement to the extent such agreement relates to the Product in the Territory
upon termination of this Agreement for any reason.

         2.5 Sales Outside the Territory. Except as otherwise set forth in this
Agreement, Celltech shall not distribute, sell or otherwise provide the Product
outside of the Territory and shall not solicit customers for the Product outside
the Territory or establish any office through


                                       8
<PAGE>


which orders are solicited or any depot at which inventories of the Product are
stored outside the Territory. Celltech shall not sell the Product to customers
outside the Territory, provided that nothing herein shall preclude Celltech from
selling the Product to any customer, wherever located, who purchases Product
with a view to its use within any country of the Territory.

         2.6 Option to Expand the Territory. If, after the Effective Date, an
Option Country joins the European Union or European Free Trade Area, Celltech,
in its sole discretion, may add such Option Country to the Territory and may
designate such Option Country as a Major European Country or a Minor European
Country. Celltech shall notify Orphan Medical of its decision within thirty (30)
days after the date Celltech first learns of such country joining the European
Union or European Free Trade Area, and, if Celltech so chooses to add such
Option Country to either the Major European Countries or Minor European
Countries, then Appendix A hereto shall be amended to so reflect such addition.

         2.7 Competitive Product. Orphan Medical acknowledges that (i) Celltech
has developed and is marketing methylphenidate in certain countries within the
Territory for Indications other than the Licensed Indications, but that
methylphenidate is occasionally used on an off-label basis to treat the Licensed
Indications; (ii) Celltech is marketing dexedrine in the United Kingdom for the
Licensed Indications; and (iii) Celltech will be marketing Equasym IR in France
for the Licensed Indications. With the exception of the off-label use of
methylphenidate in the Territory, dexedrine in the United Kingdom, and Equasym
IR in France, Celltech shall not, for five (5) years from the Effective Date of
this Agreement, either directly or indirectly through subdistributors,
sublicensees or otherwise, develop, manufacture, promote, market or distribute
products in the Territory that are competitive with the Product; provided,
however, nothing herein shall prohibit Celltech from acquiring, by stock
purchase, asset purchase or merger any company, or division of a company, that
is developing, marketing, manufacturing, promoting or distributing a competitive
product where the annual sales (or in the case of a product in development, the
projected sales) of such competitive product in the Territory are less than
twenty percent (20%) of such company's or division's total annual sales. For
purposes of this Section 2.7, a competitive product shall be one that: (a) is
approved for prescription for a Licensed Indication or (b) is used off-label for
a Licensed Indication and such off-label sales comprise more than twenty percent
(20%) of such product's sales in the Territory or more than twenty percent (20%)
of the sales of the Product in the Territory.

                                  ARTICLE III.
                              REGULATORY APPROVALS;
                      COMPLIANCE WITH LAWS AND REGULATIONS

         3.1 Marketing Authorizations. Celltech shall prepare and submit to
Orphan Medical, (i) within sixty (60) days of the Effective Date, a written plan
for obtaining approval from the EMEA to commercially promote and distribute the
Product for the cataplexy Licensed Indication and (ii) within one hundred twenty
(120) days of the Effective Date, a written plan for obtaining approval to
commercially promote and distribute the Product for the cataplexy Licensed
Indication from the Regulatory Authority of each country in the Territory not
covered by an EMEA Registration. On the basis of Orphan Medical's NDA and the
Know How and related Proprietary Information delivered pursuant to Section 3.2,
Celltech shall collect, assemble, organize and format all necessary components
required to apply for such approvals, and shall


                                       9
<PAGE>


submit such materials to the appropriate Regulatory Authorities in accordance
with Section 3.2. Celltech shall maintain, at its own expense, the Registrations
and other authorizations necessary to import, label, promote, market, sell and
distribute the Product in the Territory. Orphan Medical shall provide, at its
own cost and expense (but subject to the limitations set forth in Section 3.2),
reasonable assistance to Celltech in the acquisition of such Registrations,
including without limitation, the services set forth on Appendix H hereto. All
applications for Marketing Authorizations for the Product shall be submitted in
the name of Celltech and all Marketing Authorizations for the Product shall be
assigned to Orphan Medical upon termination of this Agreement for any reason.
Celltech shall ensure that all pages of documents submitted to Regulatory
Authorities for the purpose of obtaining Registrations and Marketing
Authorizations shall be coded as confidential.

         3.2 Regulatory Timelines. (a) Within thirty (30) days of the Effective
Date, Orphan Medical shall (i) transfer the Orphan Medical Drug Designation in
the Territory from IDIS World Medicines to Celltech, and (ii) provide Celltech
with the NDA and the Know How and the related Proprietary Information to enable
Celltech to prepare and timely file the applications to commercially promote and
distribute the Product for the cataplexy Licensed Indication in the Territory.
Celltech shall use its Commercially Reasonable Efforts to cause a pre-submission
meeting to be held with the EMEA in respect of the cataplexy Licensed Indication
within one hundred eighty (180) days of the Effective Date. Within thirty (30)
days of such meeting with the EMEA, Celltech shall report to Orphan Medical
about the content of such meeting and advise Orphan Medical as to whether
additional data or documentation or additional action is required or deemed
reasonably necessary by Celltech to obtain approval from the EMEA to
commercially promote and distribute the Product for the cataplexy Licensed
Indication. If additional data or documentation or additional action is required
or deemed reasonably necessary by Celltech to obtain such approval and Orphan
Medical has or could readily produce such data or documentation or take such
additional action, Orphan Medical shall so provide the additional data or
documentation or take the additional action at its sole cost and expense;
provided, however, that in the event the cost of any single study or other
report required by the EMEA or deemed reasonably necessary by Celltech shall
exceed * or the aggregate cost of all studies or other reports required by
the EMEA or deemed reasonably necessary by Celltech shall exceed *, Celltech
and Orphan Medical shall meet and discuss in good faith the apportionment of
such costs between them. Provided that Orphan Medical's NDA and other relevant
Know How and related Proprietary Information are deemed reasonably sufficient by
Celltech, Celltech shall, at its own expense, file the application for approval
of the Product by the EMEA as an orphan drug.

                  (b) Following approval from the EMEA to commercially promote
and distribute the Product for the cataplexy Licensed Indication, Celltech shall
use Commercially Reasonable Efforts to obtain Registration of the Product for
the cataplexy Licensed Indication (i) in the Major European Countries no later
than December 31, 2005 (the "REGISTRATION DATE") and (ii) in the other countries
in the Territory within such time frames as are consistent with the regulatory
plan submitted by Celltech to Orphan Medical as provided in Section 3.1; unless,
in any such case, additional data or documentation or additional action is
required, in which case, the timeframe shall be extended by the time required to
generate the additional data or documentation or take the additional action.
Where a Regulatory Authority requires additional data or documentation or
additional action that is not within Orphan Medical's sole obligation as


                                       10
<PAGE>


delineated in paragraph (a) above and that neither party has or could readily
produce or which cannot readily be taken by either party, the parties shall
negotiate in good faith the terms upon which such data or documentation should
be generated or actions taken by either party, if at all, or failing agreement,
to terminate this Agreement in so far as it relates to a country in the
Territory not a member of the European Union or the European Free Trade Area.

                  (c) Anything herein to the contrary notwithstanding, (i)
except as provided in paragraphs (a) and (b) above, in connection with providing
additional data and documentation or taking additional actions pursuant to this
Section 3.2, each party shall be responsible for all costs and expenses of its
respective employees, agents, contractors, sublicensees and subdistributors, and
(ii) no party shall be obligated to conduct any clinical trials after the
Effective Date.

                  (d) Following the development by Orphan Medical of a
supplemental NDA for the excessive daytime sleepiness Licensed Indication, which
such supplemental NDA shall be developed by Orphan Medical as soon as
practicable after the Effective Date, a copy thereof shall be delivered to
Celltech to enable it to prepare an application to the EMEA for approval to
commercially promote and distribute the Product in the Territory for the
excessive daytime sleepiness Licensed Indication. Such application shall be
filed by Celltech no later than the later of (i) issuance of the license to
Celltech by the EMEA for the cataplexy Licensed Indication or (ii) one hundred
eighty (180) days after Orphan Medical delivers such supplemental NDA to
Celltech, unless additional data or documentation or additional action is
required from Orphan Medical or a Third Party, in which case the one hundred
eighty (180) days shall be extended by the time required to generate the
additional data or documentation or take the additional action.

         3.3 Other Approvals. Celltech undertakes and covenants that as soon as
reasonably practicable following the Effective Date it shall take all other
actions to obtain and maintain during the Term all other approvals, licenses and
permits necessary to import, promote, market, sell and distribute the Product in
the Territory.

         3.4 Return of Initial Payment. In the event that following and as a
result of the pre-submission meeting with the EMEA, the parties mutually agree
that it is not possible or commercially viable under the prevailing
circumstances to obtain Registration for the Product in the Major European
Countries, the parties may agree to terminate this Agreement, and such
termination shall be subject to the terms of Article 14. * ountries is not
possible or commercially viable under the prevailing circumstances, then they
shall submit the matter to arbitration in accordance with the provisions of
Section 15.2 of this Agreement.

         3.5 Product Changes. Orphan Medical shall give Celltech ninety (90)
days prior written notice of any major formulation or packaging change to the
Product being requested or required by the FDA, or any other U.S. Regulatory
Authority, whenever such change affects a Registration in any country within the
Territory. Orphan Medical may change the Product, or analytical test methods as
it deems appropriate, provided Orphan Medical continues to supply


                                       11
<PAGE>


Product conforming to the Product Specifications then in effect until such times
as the Marketing Authorizations are amended to reflect such changes. In the
event of such changes, Celltech shall be solely responsible for additional
submissions and/or regulatory updates which may be required by the Regulatory
Authorities in the Territory, provided that all necessary data and information
shall be furnished by Orphan Medical at Orphan Medical's expense for such
purposes, and provided; further that in no event shall Celltech's failure to
obtain any required amendments to the Marketing Authorizations to reflect such
additional submissions and/or regulatory updates, relieve Orphan Medical of its
obligation to supply Product conforming to the Product Specifications. In the
event a Regulatory Authority in any country in the Territory requires a
formulation or packaging change to the Product, Orphan Medical and Celltech
shall cooperate to develop a mutually agreeable plan to address the regulatory
requirement, and, if necessary, to include the production of separate lots, at
Celltech's expense, for the Territory. In the event Orphan Medical and Celltech
mutually agree it is not commercially reasonable to meet such requirements,
Celltech shall cease promoting, marketing, selling and/or distributing the
Product in that country in the Territory and shall promptly terminate the
Registrations in such country. If the parties are in disagreement as to whether
it is commercially reasonable to meet such requirements, then they shall submit
the matter to arbitration in accordance with the provisions of Section 15.2 of
this Agreement.

         3.6 Clinical Trials. The parties shall keep one another fully and
currently informed as to all tests and trials that they intend to carry out for
purposes of compliance with regulatory requirements in the Territory or that
might affect Marketing Authorization applications or Registrations in the
Territory. The parties shall cooperate in the design of such tests and trials in
order to ensure to the maximum possible extent that duplication of effort shall
be avoided, and that the results shall be suitable for filing with the
Regulatory Authorities in the Territory and shall otherwise be useful for
purposes of meeting all applicable regulatory requirements. Without limiting the
generality of the foregoing, the parties shall use their Commercially Reasonable
Efforts to ensure that all clinical trials undertaken after the Effective Date,
if any, shall be designed and conducted in accordance with good clinical
practices and good laboratory practices as established for both the United
States and the European Union.

         3.7 Compliance With Applicable Laws. Celltech shall comply with all
applicable laws and regulations of each country in the Territory (including,
without limitation, any laws or regulations in the Territory governing the
distribution of a scheduled drug, as designated under regulations promulgated by
the DEA). Celltech shall also comply with all U.S. laws applicable to the
Registration, promotion, marketing, sale and distribution of the Product in the
Territory, including but not limited to U.S. Export Administration Regulations,
the US Foreign Corrupt Practices Act and all regulations promulgated by the DEA.
Celltech shall comply with all Marketing Authorizations issued in the Territory.

         3.8 Approved Product Packaging and Labeling; Relevant Testing. After
the Product receives a Marketing Authorization in any country of the Territory,
Celltech shall package and label the Product and shall include all required
labeling for Product sold in such country(ies). For all orders submitted by
Celltech after Registration is received in a particular country, Orphan Medical
shall supply to Celltech unlabeled bottles, and final labeling and packaging of
Product for such country(ies) shall be completed by Celltech. After the Product
receives Marketing Authorization in a country in the Territory, Celltech shall
be solely responsible for all final


                                       12
<PAGE>


release testing in such country(ies) and for ensuring in such country(ies) that
the Product labeling and packaging complies with the Marketing Authorizations
and all other applicable laws of each such country in the Territory. Celltech
shall provide Orphan Medical with copies of all foreign language labels. To the
extent permitted by applicable laws and regulations in each country in the
Territory, all labels shall identify Orphan Medical as the manufacturer of the
Product for Celltech.

         3.9 Steering Committee. Within a reasonable period of time after the
Effective Date, Orphan Medical and Celltech shall form a Steering Committee made
up of commercial and technical employees from both companies that shall have
certain decision-making authority, and provide oversight for the administration
of this Agreement. Each party shall maintain two (2) members on the Steering
Committee with other members added as needed. The parties shall each select one
of its representatives to serve as a co-chairperson of the Steering Committee.
The Steering Committee shall have the authority to conduct the following
activities and such other activities as may be agreed to in writing by the
parties: (a) review ongoing regulatory issues, (b) review the medical aspects of
standards of care in the Territory, (c) review clinical developments across
territories, (d) review marketing campaigns and new marketing plans, (e) review
sales activities and results, (f) review aspects of Product manufacturing
campaigns and Product forecasts, consignment and non-consignment inventory
stocks and ordering, and (g) review the arrangement for distributing Product on
a Named Patient Basis. In the event and to the extent that the Steering
Committee is unable to come to a consensus on any matter relating to the
development or manufacture of the Product or the Registration, packaging,
labeling, promoting, marketing, sale or distribution of the Product outside the
Territory, the views of the Orphan Medical Steering Committee members shall
prevail. In the event and to the extent that the Steering Committee is unable to
come to a consensus on any matter relating to the Registration, packaging,
labeling, promoting, marketing, sale or distribution of the Product within the
Territory, the views of the Celltech Steering Committee members shall prevail.
Notwithstanding the foregoing, in the event a particular matter for which there
is no consensus of the Steering Committee could, in the good faith judgment of
the party who does not have the ultimate decision making authority as to such
matter (as provided in the previous two sentences), materially affect the rights
or obligations under this Agreement of such party, Orphan Medical and Celltech
agree to use Commercially Reasonable Efforts to resolve the matter in a manner
which will minimize the impact on such rights or obligations of such party.
During each Contract Year, the parties shall hold at least four (4) regular
meetings of the Steering Committee. Members of the Steering Committee may
participate in meetings of the Steering Committee in person or by conference
telephone call. At least one (1) of the four (4) Steering Committee meetings
shall be conducted in-person. Employees of each party who are not members of the
Steering Committee may attend meetings of the Steering Committee as required.
In-person Steering Committee meetings shall alternate between Orphan Medical's
designated facility and a facility designated by Celltech. The co-chairpersons
of the Steering Committee shall alternate responsibility for the preparation of
minutes setting forth discussions made at each committee meeting, with the
Orphan Medical Chairperson preparing minutes for the first Steering Committee
meeting; provided, however, that such minutes shall not become official until
agreed upon by both co-chairpersons.

                        ROYALTIES AND MILESTONE PAYMENTS

         4.1 Milestone Payments. In consideration of the rights and licenses
granted hereunder, Celltech shall pay to Orphan Medical milestone payments
totaling $15,500,000 US Dollars according to the following schedule:

                  (a) $2,500,000 US Dollars on the Effective Date.

         *


         4.5 Exchange Rates. For purposes of determining the amount of Net Sales
and the amount of royalties payable pursuant to Section 4.2 during any calendar
quarter, the total of all sales in each currency during such quarter shall be
converted into US Dollar currency at the average daily exchange rate for such
calendar quarter as reported by oanda.com or, if such website is not available,
the Wall Street Journal. For purposes of determining the minimum royalty amount
for each Contract Year as provided in Section 4.3, the amounts set forth therein
shall be converted into US dollar currency at the average daily exchange rate
for such Contract Year as reported by oanda.com or, if such website is not
available, The Wall Street Journal.

         4.6 Taxes. Celltech shall be entitled to deduct from royalties paid
hereunder the amount of any withholding taxes or other taxes, levies or charges
required to be withheld by Celltech, to the extent Celltech pays to the
appropriate governmental authority on behalf, and for the account of, Orphan
Medical such taxes, levies or charges. Celltech shall use reasonable efforts
(including making, or assisting Orphan Medical in making, any relevant
application to any tax authority) to minimize any such taxes, levies or charges
which are required to be withheld by Celltech from royalties paid hereunder and
paid on behalf of Orphan Medical by Celltech. Celltech shall promptly deliver to
Orphan Medical proof of payment of all such taxes, levies and other charges,
together with copies of all communications from or with such governmental
authority with respect thereto.

         4.7 Reports. Each royalty payment made by Celltech hereunder shall be
accompanied by a report showing all revenue generated by sales of the Product to
Third Parties (including all sales by Subdistributors and Sublicensees) during
the immediately preceding quarter, the computation of Net Sales, and the
calculation of royalty payments due for such quarter, all on a
country-by-country basis. If actual Net Sales of any Subdistributor or
Sublicensee for that quarter is unavailable at the time such quarterly report is
due, Celltech shall include in its report for that quarter a good faith estimate
of such Net Sales, and an appropriate adjustment for the difference between the
actual and estimated Net Sales shall be made in the report for the following
quarter, with a corresponding adjustment in the amount of royalties payable in
respect of that quarter.

         4.8 Books and Records; Audit. Celltech shall keep for at least three
(3) years or such longer period as may be required by law following the end of
the calendar year to which they pertain, accurate and complete records showing
all sales of the Product by Celltech and its Subdistributors and Sublicensees.
Such records shall include all information reasonably necessary to verify the
total amount and computation of earned royalties hereunder, and shall be open to
inspection and audit, during reasonable business hours, to the extent necessary
to verify the amount of such royalties. Such inspection and audit shall be
conducted at the request and expense of Orphan Medical by an independent
Certified Public Accountant appointed by Orphan Medical. Such inspection and
audit shall be made not more often than once in each Contract Year. Such
Certified Public Accountant shall undertake a confidentiality obligation to
Celltech permitting it to disclose only to Orphan Medical the amount of the
royalties due hereunder, and no other information. Orphan Medical shall bear the
costs of any such inspection and audit; provided that if any inspection and
audit reveals an underpayment of more than five percent


                                       16

relating to the Product required by the Regulatory Authorities in each country
in the Territory and shall deliver a copy of each such report in hardcopy and on

Territory.

                  (b) Subject to Section 5.2(c) below, in the event of a recall,
market withdrawal or correction (i) by reason of the failure of all or part of
the Product supplied by Orphan Medical to meet the Product Specifications, any
requirement of the FDA or any Marketing Authorization or other requirement of
applicable law that is not the result of any action or omission of Celltech or
its Subdistributors or Sublicensees as described in paragraph (c) below or (ii)
because Product that meets the Product Specifications, by whomsoever
manufactured, is inherently defective, unsafe, dangerous or may harm users of
the Product, Orphan Medical shall bear the costs of such recall, market
withdrawal or correction (including without limitation Celltech's reasonable
attorney's fees).

                  (c) In the event of a recall, market withdrawal or correction
by reason of the failure of Celltech to have obtained or properly maintained or
complied with a Marketing Authorization or as a result of Celltech's (or its
Subdistributors', Sublicensees' or Third Party manufacturers') breach of any of
their obligations under this Agreement (including without limitation Section
3.7), or the willful misconduct or negligent acts or omissions of Celltech (or
its Subdistributors, Sublicensees' or Third Party manufacturers'), Celltech
shall bear all costs of such recall, market withdrawal, or correction (including
without limitation Orphan Medical's reasonable attorneys' fees).

                  (b) Celltech agrees to inform Orphan Medical in writing of all
significant complaints regarding the Product that relate to Product
Specifications within fifteen (15) business days after Celltech's receipt
thereof in all countries of the Territory. Celltech shall also provide written
quarterly reports of all complaints regarding the Product, regardless of
significance, in English, as well as the actions taken by Celltech to address
all such complaints. Such reports shall be delivered to Orphan Medical within
thirty (30) days after the end of each calendar quarter during the Term.

         5.5 Translations. Celltech shall provide Orphan Medical English
translations of any material regulatory correspondence received in a language
other than the English language relating to a Serious Adverse Event (as defined

translations of any other regulatory correspondence and reports delivered
pursuant to Sections 5.1, 5.3 or 5.4 to the extent Celltech has otherwise
translated such correspondence and reports for its own purposes.

         5.6 Manufacture; Quality. Subject to Article VII, Orphan Medical agrees
to manufacture Celltech's requirements for Product as necessary to satisfy
Celltech's forecasts and purchase orders submitted by Celltech pursuant to this
Agreement. Products delivered to Celltech pursuant to this Agreement shall be
manufactured in accordance with the Quality Agreement negotiated and finalized
between Orphan Medical and Celltech prior to Marketing Authorization approval in
any country in the Territory, such agreement to be substantially in the form
attached hereto as Appendix E. Such Quality Agreement shall be agreed upon by
the parties no later than twelve (12) months after the Effective Date. The
Quality Agreement shall include the obligations and pharmaceutical
responsibilities of Orphan Medical, Orphan Medical's sub-contractors and
Celltech relating to the quality assurance requirements for the manufacture and
supply of the Product, all in accordance with cGMP and applicable regulatory
requirements.

         5.7 Product Specifications. Product supplied to Celltech by Orphan
Medical shall meet the Product Specifications that are approved by the
Regulatory Authorities in the Territory. Should the approved Product
Specifications differ from the specifications contained in Orphan Medical's NDA
which are set forth on Appendix C, the Product Specifications approved by the
Regulatory Authorities shall control.

         5.8 Manufacturing Audits by Celltech. Upon sixty (60) days prior
written notice for cause, or with one hundred eighty (180) days written notice
for an annual audit, Celltech or a representative thereof shall have the right,
if within the power of Orphan Medical to grant such right, to participate in the
conduct of compliance or other inspections, audits and/or investigations of the
operations and facilities where the Product and the raw materials and components
used to manufacture, package, inspect, test, store and supply the Product,
including, without limitation, the API and the Components, are manufactured,
packaged, inspected, tested and stored. Such inspections, audits and/or
investigations shall take place during normal business hours at the relevant
manufacturing site(s) in the presence of Celltech and Orphan Medical's
representatives and Celltech shall abide by any confidentiality requirements or
security procedures of Orphan Medical's suppliers. Orphan Medical shall
facilitate and lead the audit, and it shall be Orphan Medical's responsibility
to discuss any audit findings with its sub-contractors and suppliers. Celltech
and Orphan Medical along with any other licensing partner


                                       18
<PAGE>


will agree upon a final single audit report that will be sent to the vendor by
Orphan Medical. In the event of any disagreement among the parties relating to
the audit report, Orphan Medical shall be the deciding entity and will finalize
the audit report. Orphan Medical shall require its sub-contractors and suppliers
to take all reasonably necessary corrective actions identified by Celltech as
necessary to comply with cGMP requirements and Registrations in the Territory.
In the case where a vendor will not allow Celltech to accompany Orphan Medical
during such audit, Orphan Medical will either audit on behalf of Celltech, or
will jointly, with Celltech engage an independent third party to audit the
supplier on behalf of both parties. Orphan Medical is generally allowed one
audit each year of each vendor. If additional costs are imposed due to
accompaniment of Celltech with Orphan Medical during such audits, Celltech shall
bear the burden of any additional costs.

                                  ARTICLE VI.
                                MARKETING EFFORTS

         6.1 Marketing Efforts. Celltech shall have, directly or through its
Subdistributors or Sublicensees, the following obligations with respect to the
marketing and distribution of the Product in the Territory:

                  (a) To use its Commercially Reasonable Efforts to promote,
market, sell and distribute the Product in the countries in the Territory where
Registrations are in good standing; provided, however, * ;

                  (b) To promptly respond to all inquiries or complaints from
purchasers of the Product;

                  (c) To maintain adequate and qualified staff to enable it to
fully perform its obligations hereunder;

                  (d) To provide adequate and appropriate training to its staff
concerning the Product; and

                  (e) To conduct its business in a professional manner.

         6.2 Approved Product Claims. Celltech shall not make and shall cause
its Subdistributors and Sublicensees to not make claims to any Third Party
concerning the Product except as contained in or permitted by the relevant
Marketing Authorization or as approved in the Territory by the appropriate
Regulatory Authority.

         6.3 Development of Marketing Strategy. Celltech agrees to cooperate in
the development of a consistent message strategy to promote the Product in an
effort to protect and strengthen branding. The global positioning of the Product
for the U.S. and the Territory should be discussed before Celltech launches the
Product in a country in the Territory and at least once per year (or more
frequently if reasonably requested by Orphan Medical) to ensure a message which
is consistent with the local Marketing Authorizations and local treatment
guidelines in


                                       19
<PAGE>


such country, and, where possible, consistent with the international message.
Celltech and Orphan Medical agree to work in good faith to develop such a
strategy.

         6.4 Marketing Materials. Celltech agrees to provide Orphan Medical with
copies of all marketing and promotional materials within thirty (30) days of
first use. Celltech shall be solely responsible for the text, graphics, and
compliance of such materials with the laws and regulations of the Territory, but
may rely (without further investigation) on all Product information provided by
Orphan Medical, except that Celltech may not rely on such information to the
extent Celltech knows or reasonably should know that such information is
inaccurate.

         6.5 Sales and Technical Literature Developed by Orphan Medical. From
time to time during the Term Orphan Medical shall provide to Celltech reasonable
quantities of such training, sales and technical literature and materials
relating to the Product as Orphan Medical may have prepared, including, without
limitation, the materials set forth on Appendix H hereto, and shall make
available copies of promotional artwork it may have. The cost of printing
quantities or customizing materials shall be borne by Celltech. Orphan Medical
shall provide the same to Celltech in electronic format. Orphan Medical shall
also provide Celltech with copies of all post-marketing studies and updates to
its regulatory filings that it provides to the FDA. Celltech shall use such
materials solely as provided under this Agreement. Orphan Medical retains all
right, title and interest in and to such materials subject, however, to the
terms of this Agreement.

         6.6 Marketing Reports. (a) At least one hundred eighty (180) days prior
to the anticipated date of the First Commercial Sale, Celltech shall provide
Orphan Medical with sales and marketing plans for the Major European Countries
for the balance of the Contract Year in which such First Commercial Sale occurs;
provided, however, that in respect of Italy, Celltech shall deliver a proposal
to appoint a sub-licensee within one hundred eighty (180) days prior to the
anticipated date of the First Commercial Sale, and shall provide Orphan Medical
with a sales and marketing plan for Italy as soon as practicable after executing
an agreement with a sub-licensee relating to distribution of the Product in
Italy.

                  (b) By 31 January of each Contract Year following the year in
which the First Commercial Sale occurs, Celltech shall provide Orphan Medical
with a written report summarizing its sales and marketing activities in the
Major European Countries for the immediately preceding year, and sales and
marketing plans in the Major European Countries for the current Contract Year.
Simultaneously with delivery of each marketing report described in this Section
6.6(b), Celltech shall deliver reports as to the sales and marketing activities
in the Minor European Countries (for the same periods as provided for the Major
European Countries), provided that such reports need only outline the most
important aspects and plans of the sales and marketing in such Minor European
Countries. Each report shall include the potential market for the Product in all
countries of the Territory where Registration has been achieved and is
anticipated during the Contract Year in question, and other information that
Celltech deems helpful to determine the market for Product and the proper
marketing methods for the same.

         6.7 Cooperation. Orphan Medical and Celltech agree to maintain open
communications relating to the ongoing performance of this Agreement to ensure
joint understanding of current or new issues, data, and information. Orphan
Medical shall answer reasonable technical or marketing questions Celltech may
submit to Orphan Medical. Celltech


                                       20
<PAGE>


acknowledges that Orphan Medical does not have international marketing and
regulatory staff for preparation of regulatory submissions and marketing plans.
Orphan Medical and Celltech agree to provide each other copies of market
research study protocols and subsequent results therefrom, which studies are
designed to generate qualitative and/or quantitative data pertaining to the
Product, subject to any Third Party rights therein.

         7.3 Consignment of Product.

                  (a) General. Within a reasonable period in advance of the
anticipated date of the First Commercial Sale, to the extent importation is then
permitted under applicable law, Orphan Medical shall transfer to Celltech's
specified facility in England at least one full lot quantity * of the Product
(such Product, together with subsequent inventory of the Product to be held by
Celltech as baillee pursuant to the terms of this Section 7.3, shall be
"CONSIGNMENT INVENTORY"). Orphan Medical shall thereafter transfer to Celltech
such quantities of the Product as the parties, with input from the Steering
Committee, may subsequently agree in order that the amount of Consignment
Inventory plus the amount of finished goods inventory maintained by Celltech
shall equal approximately the next six (6) months anticipated demand for the
Product in the Territory; provided, that, Orphan Medical shall in no event be
required to transfer, and Celltech shall in no event be required to hold
Consignment Inventory of more than one and one-half full lot quantities *
without its prior written consent. Celltech shall hold the Consignment Inventory
as baillee for and on behalf of Orphan Medical. Celltech hereby acknowledges and
agrees that Celltech's holding the Consignment Inventory in its premises
pursuant to the terms of this Section 7.3 shall constitute a gratuitous bailment
and not a bailment for valuable consideration governed by the U.K. Supply of
Goods and Services Act 1982. The Product in the Consignment Inventory will at
all times remain under the control of Celltech and be held for and on behalf of
Orphan Medical by Celltech as baillee until such time as the Product is removed
from the Consignment Inventory by Celltech in fulfillment of a purchase order
placed by Celltech in accordance with Section 7.4 hereof or repossessed by
Orphan Medical or returned by Celltech in accordance with Section 7.3(e)(iii)
hereof.

                           (ii) Celltech agrees to act as the fiscal
                  representative of Orphan Medical for purposes of customs,
                  duties and VAT, and Celltech shall be solely responsible for
                  payment of all such duties and taxes to the appropriate U.K.
                  authorities when due.

                           (iii) Celltech shall pay (or reimburse Orphan Medical
                  for) all freight charges, insurance in transit, taxes
                  (including import VAT) and import duties incurred in
                  connection with the transfer of the Consignment Inventory from
                  Orphan Medical's designated supplier in the U.S. to Celltech's
                  facilities.

                  (c) Storage and Risk.

                           (i) Celltech will at all times store the Consignment
                  Inventory in premises which have been certified by the
                  Medicines Healthcare Regulatory Authority and any other
                  relevant Regulatory Authority as suitable for U.K. Schedule 4,
                  Part 1 controlled substances and as otherwise provided in
                  Section 7.11.

                           (ii) In the event that any item of Consignment
                  Inventory is lost or damaged through no fault of Orphan
                  Medical, Celltech shall indemnify Orphan Medical in respect of
                  any such loss or damage by paying the Transfer Price for each
                  item lost or damaged, plus duties and VAT, if any.

                           (iii) Celltech will store the Consignment Inventory
                  separately from any goods that belong to Celltech or any Third
                  Party and shall clearly mark and identify the Consignment
                  Inventory as being held on behalf of Orphan Medical.

                           (iv) Celltech shall at its expense at all times
                  maintain adequate insurance covering any risk of loss or
                  damage to the Consignment Inventory for its full Transfer
                  Price and naming Orphan Medical as sole loss payee and shall
                  forward a copy of evidence of such insurance and any amendment
                  thereto to Orphan Medical.

                  (d) Records. Celltech shall maintain full and accurate records
showing the quantity of Consignment Inventory, the lot identification,
expiration dates and such other information as is necessary to enable a Third
Party to identify that each item of Consignment Inventory forms part of the
Consignment Inventory and is being held on behalf of Orphan Medical under the
supervision and control of Celltech.

                  (e) Termination.

                           (i) The bailment created pursuant to this Section 7.3
                  shall terminate with immediate effect on the last day of the
                  Term of this Agreement.

                           (ii) Orphan Medical may also terminate the bailment
                  created pursuant to this Section 7.3 with immediate effect, by
                  giving written notice to that effect to Celltech, if any
                  liquidation, receivership, administration or other insolvency
                  procedure is commenced or threatened with respect to Celltech
                  or any entity


                                       23
<PAGE>


                  which has control over Celltech. Orphan Medical may also
                  terminate this Agreement if any action is taken or threatened
                  which might jeopardise Orphan Medical's rights in the
                  Consignment Inventory.

                           (iii) Termination of the bailment for whatever reason
                  shall be without prejudice to the accrued rights of a party.
                  Celltech shall not thereafter use any items of Consignment
                  Inventory or remove any items from Consignment Inventory
                  without the specific prior written consent of Orphan Medical.
                  Upon such termination, Celltech's obligations under this
                  Section 7.3 shall continue in full force and effect until such
                  time as Orphan Medical has repossessed the Consignment
                  Inventory as provided in paragraph (f) or Celltech has
                  returned the Consignment Inventory by shipment to Orphan
                  Medical Ex Works (Incoterms 2000) at the Celltech facility at
                  which it is kept.

                  (f) Return of Consignment Inventory. Orphan Medical shall be
entitled to repossess the Consignment Inventory immediately upon termination of
the bailment or prior to termination if Orphan Medical determines in its sole
discretion that repossession is necessary for any reason. Celltech, or any
person managing Celltech's activities, shall give any duly authorised
representative or agent of Orphan Medical such access to Celltech's premises as
are required for purposes of repossessing the Consignment Inventory.

                  (g) Periodic Review. At any time and from time to time, either
party may request the other party to discuss and consider in good faith changes
in, or termination of, the arrangements for Consignment Inventory, whereupon the
parties shall be mutually obligated to negotiate in good faith as to such
matters.

         7.4 Purchase Orders.

                  (a) Content. All purchase orders placed by Celltech shall be
in writing and shall state the quantity of Product, the delivery date, shipping

pursuant to Section 7.3) and such other similar information as may be reasonably
requested by Orphan Medical.

                  (b) Lead Time. *

                  (e) Miscellaneous. Orphan Medical shall use its Commercially
Reasonable Efforts to fill purchase orders that exceed the quantity limits

than one hundred twenty (120) days in advance of the requested delivery date(s)
as required by paragraph (b) above in respect of purchase orders to be filled by
Orphan Medical from other than Consignment Inventory. No accepted order may be
modified or canceled by either party except as agreed in writing by the parties.

provide prompt written notice to Celltech in the event of any anticipated delays

delivery at the earliest possible date so as to minimize the impact on Celltech,
provided, however, the foregoing shall in no way modify or mitigate Orphan
Medical's obligation to supply Product properly ordered in accordance with this
Agreement or Celltech's rights and remedies under this Agreement in respect of
any failure to timely supply, including Celltech's right to assert its remedies
in respect of a breach hereof and Celltech's rights to appoint a Third Party
manufacturer in accordance with Section 2.1(b) or to terminate this Agreement in
accordance with Section 14.2(b). Orphan Medical shall send Celltech on the date

of Celltech's orders for Product hereunder in a timely manner, Orphan Medical
shall equitably allocate its available sources and supplies among Celltech,
Orphan Medical and Orphan Medical's other partners (distributors, licensees,
agents, etc.) and internal needs, taking into consideration the respective
requirements of each of the parties during a reasonable time period prior to
allocation and their requirements during the allocation period, provided,
however, the foregoing shall in no way modify or mitigate Orphan Medical's
obligation to supply Product properly ordered in accordance with this Agreement
or Celltech's rights and remedies under this Agreement in respect of any failure
to timely supply, including in respect of a breach hereof and Celltech's rights
to appoint a Third Party manufacturer in accordance with Section 2.1(b) or to

thirty-six (36) months at the time of its delivery Ex Work's Orphan Medical's
designated supplier pursuant to Section 7.5.

                  (b) The Product delivered in the initial transfer of
Consignment Inventory from Orphan Medical to Celltech made in accordance with
the first sentence of Section 7.3(a) shall have minimum expiration dating of
forty-two (42) months at the time it is delivered to Celltech's facility in
England. Thereafter, all Product delivered by Orphan Medical as Consignment
Inventory pursuant to Section 7.3 shall have minimum expiration dating of
thirty-six (36) months at the time it is delivered to Celltech's facility in
England. Celltech shall not be required to draw out of Consignment Inventory any
Product with expiration dating of less than twenty-four (24) months on the date
that it is drawn out of Consignment Inventory; provided, however, that if the
Consignment Inventory shall at any time contain Product with less than
24-month's expiration dating, Celltech shall use Commercially Reasonable Efforts
to sell such Consignment Inventory, and provided, further, however, that if
Celltech shall not be able to sell such short-dated Consignment Inventory,
Celltech shall, at Orphan Medical's direction, either return such Product to
Orphan Medical Ex Work's Celltech's facility in England or destroy the Product
and provide the certification described in Section 7.12, and in either such
event Orphan


                                       27

Medical shall reimburse Celltech for all amounts paid by Celltech pursuant to
Sections 7.3(b)(ii) and (iii).

                  (c) In the event the applicable Regulatory Authority grants an
expiration date of less than thirty-six (36) months, Orphan Medical and Celltech
shall negotiate in good faith a reasonable minimum expiration, taking into
account the differing expiration dates set forth herein for Product which is and
Product which is not drawn out of Consignment Inventory.

                  (d) Celltech shall not sell any Product beyond its stated
expiration date.

         7.10 Certificate of Analysis. With each delivery of the Product into
Consignment Inventory pursuant to Section 7.3 or to Celltech from other than
Consignment Inventory, Orphan Medical shall provide to Celltech (i) a
Certificate of Analysis and Certificate of Conformity confirming that the
Product has been manufactured in accordance with cGMP and the Product
Specifications, (ii) a copy of all batch documentation from the Product
manufacturer for the first three (3) batches of Product delivered to Celltech
and (iii) a copy of the annual stability test report, provided that the
provision of the certificates and other documents listed in (i) - (iii) above
shall not release Celltech from any of its obligations hereunder, including,
without limitation, its obligation to conduct all necessary release testing to
ensure that the Products distributed in the Territory comply with all applicable
regulatory requirements in the Territory.

         7.11 Storage. Celltech shall at its own expense maintain adequate and
suitable storage facilities for the storage of Consignment Inventory and Product
delivered to Celltech from other than Consignment Inventory, in each case in
accordance with cGMP, the Marketing Authorizations, and all applicable laws and
regulations. Orphan Medical or its representative shall have the right no more
than twice per calendar year to inspect, during normal business hours, such
storage facilities upon sixty (60) days prior written notice.

         7.12 Rejection of Shipments For Product Non-Conformance. If Celltech
rejects a shipment from other than Consignment Inventory on the determination
that such shipment of Product fails to conform to the purchase order therefor or
a shipment of Consignment Inventory or Product delivered to Celltech from other
than Consignment Inventory or drawn by Celltech out of Consignment Inventory on
the grounds that it fails to conform to the Product Specifications, Celltech
shall give written notice of such rejection to Orphan Medical within fifteen
(15) days after receipt thereof, in the case of apparent non-conformance, and
sixty (60) days of the receipt of definitive test results obtained pursuant to
Section 7.13 in the case of non-conformance established by such tests. Such
notice of rejection shall specify the manner in which the Product fails to
conform to the relevant purchase order, or otherwise fails to conform to the
Product Specifications. If Celltech fails to provide Orphan Medical such notice
in respect of Product delivered to Celltech pursuant to a purchase order,
whether drawn from Consignment Inventory or otherwise, within fifteen (15) or
sixty (60) days, as the case may be, of the date of delivery, the Product shall
be deemed accepted by Celltech; provided, however, that such deemed acceptance
shall not (i) impair Celltech's right to reject shipment or recover damages in
respect of any non-conformance that is not apparent and cannot be determined by
such tests or (ii) reduce, diminish or alter Celltech's rights to
indemnification as specified in Article IX hereof or to terminate this Agreement
in accordance with Section 14.2(b). If Celltech expects to make a claim against
Orphan Medical in accordance with this Section 7.12, Celltech shall not dispose
or


                                       28
<PAGE>


allow the disposal of the Product in question without the express written
authorization and instructions of Orphan Medical. Any such instructions from
Orphan Medical, or Celltech's compliance therewith, shall not relieve Celltech
of its obligation to dispose of any Product in accordance with all applicable
laws and regulations in the relevant country in the Territory. Celltech shall
not return any rejected Product to Orphan Medical without a Return Material
Authorization ("RMA") from Orphan Medical. Orphan Medical shall promptly issue a
RMA for any reasonably rejected Product, provided, however, appropriate samples
may be retained by Celltech as evidence of the basis for such rejection by
Celltech. Proof of destruction or disposal shall be certified in writing to
Orphan Medical by an officer of Celltech. Within thirty (30) days of receipt of
a statement detailing and documenting all of Celltech's costs and expenses
associated with Orphan Medical's delivery of non-conforming Products, including
without limitation, any payments made or other Indemnification Amounts arising
out of Claims and the return, destruction or disposal of such Product pursuant
to this Section 7.12, Orphan Medical shall reimburse Celltech for all such
amounts. Any disputes between the parties relating to such reimbursement amounts
shall be resolved in accordance with the procedures set forth in Section 15.2

         7.13 Testing of Product Upon Receipt. Celltech shall, as soon as
practical after receipt of Product into Consignment Inventory or from other than
Consignment Inventory, examine the Product for any apparent non-conformance and
carry out or have carried out, routine laboratory testing and other chemical
analysis of the Product as required by the relevant Marketing Authorizations
and/or Regulatory Authority(ies). Celltech shall promptly notify Orphan Medical
if such examination or testing establishes the basis to reject the Product for
non-conformance. Any such notice shall identify the specific claims of
non-conformance and include copies of relevant test results or other materials
indicating such non-conformance. Upon receipt of a notification of
non-conformance, Orphan Medical and Celltech shall compare test results obtained
during release testing of the Product by Orphan Medical to the results Celltech
obtained during acceptance testing to evaluate the potential cause of
discrepancy. If Orphan Medical confirms such non-conformity, it shall promptly
so notify Celltech. If Orphan Medical does not confirm such non-conformity, it
shall promptly so notify Celltech, and the parties shall submit the disputed
Product shipment for testing to an independent testing laboratory or other
independent Third Party expert mutually acceptable to the parties.
Notwithstanding Section 15.2, the findings of the testing laboratory or Third
Party expert shall be binding on the parties. The expenses of such testing shall
be borne by Orphan Medical if the non-conformity is confirmed, and otherwise by
Celltech. Without limiting Celltech's other remedies as herein provided, Orphan
Medical shall promptly replace properly rejected Product. Celltech shall return
such Product or, if requested by Orphan Medical, destroy the Product and provide
the certification described in Section 7.12.

MEDICAL MAKES NO WARRANTIES, EXPRESS OR IMPLIED, INCLUDING WITHOUT LIMITATION
THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND
NON-INFRINGEMENT WITH RESPECT TO THE PRODUCT OR CELLTECH'S SALE AND DISTRIBUTION
THEREOF IN THE TERRITORY. The warranties given by Orphan Medical are for the
sole benefit of Celltech and Celltech shall not extend such warranties to any
customer thereof or any Third Party. This provision does not affect the right of
any patient to pursue legal remedy in the event Orphan Medical provides Product
that is adulterated or misbranded or if Product does not meet Product
Specifications. Except as provided in Section 2.1, nothing in this Agreement
shall be construed as, and Orphan Medical expressly disclaims, any warranty or
agreement to furnish any manufacturing information beyond that required to
obtain Registrations for the Product in the Territory. Celltech agrees that as
between Celltech and Orphan Medical, Celltech alone shall be liable, to the
exclusion of Orphan Medical, for the breach of any warranties given by Celltech,
its Subdistributors or its Sublicensees to customers or others regarding the
Product, provided, however, nothing herein shall reduce, diminish or alter
Celltech's rights as herein provided including its right to assert claims
against Orphan Medical in respect of the same facts that form or might form the
basis of Claims against Celltech by its Subdistributors or Sublicensees and its
or their customers.

         8.3 Celltech Warranties. Celltech represents and warrants to Orphan
Medical that:

                  (a) It is a corporation duly organized, validly existing and
in good standing under the laws of England and has the corporate power to own
its assets and properties and to carry on its business as now being and
heretofore conducted.

                  (b) It has all requisite power and authority (corporate and
otherwise) to enter into this Agreement and it has duly authorized, by all
necessary action, the execution and delivery hereof by the officer or individual
whose name is signed on its behalf below. Celltech's execution and delivery of
this Agreement does not and will not conflict with or result in a breach of or a
default under its organizational documents or any agreement, instrument, order,
law or regulation applicable to it or by which it or the Product may be bound.
This Agreement has been duly and validly executed and delivered by Celltech and
constitutes Celltech's valid and legally binding obligation, enforceable against
Celltech in accordance with its terms, except as enforcement may be limited by
laws of bankruptcy or insolvency or other laws of general application relating
to or affecting the enforcement of creditor's rights and general equitable
principles.

                  (c) It shall and shall cause its Subdistributors, Sublicensees
and Third Party manufacturers to manufacture (if applicable), store, package,
label, promote, market, sell and distribute the Product in compliance with this
Agreement, the Registrations and all applicable laws and regulations in the
Territory.

                  (d) Celltech shall not, and shall cause its Subdistributors,
Sublicensees and Third Party manufacturers to not knowingly, infringe any Third
Party patents, copyrights, trademarks, trade secrets or other Third Party

                  or any action taken or proposed to be taken by Celltech
                  pursuant hereto or thereto or in connection with the
                  transactions contemplated hereby, or (B) would if adversely
                  determined, singly or in the aggregate, prohibit or materially
                  impair Orphan Medical's or Celltech's ability to perform its

                  decrees, writs, awards, stipulations, injunctions of any

                  if adversely determined, singly or in the aggregate, prohibit
                  or materially impair Celltech's ability to perform its
                  obligations under this Agreement.

provided in this Agreement, including, without limitation, the representations
and warranties set forth in Section 8.l, (ii) an allegation that bodily injury
(including death) or tangible personal property damage was caused by, resulted
from or arose out of the use of the Product for a Licensed Indication by
whomsoever such Product was sold (including Celltech, its Subdistributors and
Sublicensees) and regardless of the legal theory on which such Claim is based,
except, however, where such bodily injury and/or property damage is due to (a) a
circumstance described in Section 9.2(i) or 9.2(iii) hereof or (b) failure of a
Third Party manufacturer appointed by Celltech pursuant to Section 2.1 to
manufacture, store or ship the Product in accordance with cGMP, the Marketing
Authorizations and other applicable laws and regulations or due to the action or
inaction of such Third Party manufacturer which causes the Product to be
adulterated or misbranded within the meaning of the United States Food, Drug and
Cosmetic Act, as in effect at the time of shipment; and (iii) negligence, gross
negligence or willful misconduct of or attributable to Orphan Medical, its
sublicensees (other than Celltech, its Subdistributors, Sublicensees or Third
Party manufacturers), contractors, manufacturers and its or their directors,
officers, agents, employees, consultants or clinical investigators in connection
with the manufacture, storage or supply of API and/or the Product.

         9.2 Indemnification by Celltech. Celltech agrees to indemnify, defend
and hold harmless Orphan Medical and its directors, officers, employees and
agents from and against all Claims and Indemnification Amounts arising out of
(i) a breach by Celltech of any representation, warranty or covenant provided in
this Agreement, (ii) an allegation that bodily injury (including death) or
tangible personal property damage was caused by, resulted from or arose out of
the Products sold by Celltech, its Subdistributors, Sublicensees or Third Party
manufacturers that were used other than for a Licensed Indication, regardless of
the legal theory on which such Claim is based, except, however, where such
bodily injury and/or property damage is due to a circumstance described in
Sections 9.1(i) and 9.1(iii) hereof, (iii) negligence, gross negligence or
willful misconduct of or attributable to Celltech, its Subdistributors,
Sublicenses or Third Party manufacturers and its or their directors, officers,
agents, employees, consultants or clinical investigators in connection with the
storage, packaging, labeling, promotion, marketing, sale and distribution of the
Product in the Territory; and (iv) any express or implied warranty, whether oral
or written, including any implied warranty or the merchantability or fitness of
the Product for a particular purpose asserted by any customer of Celltech, its
Subdistributors or Sublicensees, if such warranty was extended by or arising
from any undertaking, action or inaction of Celltech, its Subdistributors or
Sublicensees.

         9.3 Procedure. A party seeking indemnification (an "INDEMNIFIED PARTY")
shall give the other party (an "INDEMNIFYING PARTY") written notice of any Claim
promptly upon becoming aware thereof. The indemnifying party shall have sole and
exclusive control of the defense of any Claim, including the choice and
direction of legal counsel. The indemnified party shall have the right to
participate in such defense through its own counsel, at its own expense. Neither
party may settle or compromise any Claim for which indemnification is being
sought without the written consent of the other party, which may not be
unreasonably withheld.

                          INTELLECTUAL PROPERTY RIGHTS
                               PERFECTION AND USE

         10.1 License Perfection. In the event that the execution and filing of
any document is required in connection with the license granted in Section 2.2
to Celltech for the Trademark or Patent Rights under the laws of any country in
the Territory, Celltech shall promptly notify Orphan Medical, and Orphan Medical
shall cause such document to be executed and filed, and Celltech shall sign such
document if necessary and otherwise cooperate in the filing thereof.

         10.2 Quality Standards. All Products sold and marketed under the
Trademark by Celltech or its Subdistributors or Sublicensees, including all
related advertising, promotional materials, and all other related uses of the
Trademark shall comply with the reasonable trademark use standards adhered to by
Orphan Medical in the manufacture, sale and promotion of the Product, which such
standards are set forth in Appendix I. In particular, and without limiting the
generality of the foregoing, upon reasonable request by Orphan Medical, Celltech
shall provide Orphan Medical with samples of Products bearing the Trademark, as
well as copies of all materials, including but not limited to brochures,
professional literature, packaging and consumer instructions, which are created
or intended for use by Celltech, its Subdistributors and/or Sublicensees in the
advertising, promotion, marketing or sale or other distribution of the Product
in the Territory, for examination and testing to verify compliance with the
trademark use standards set forth in Appendix I. Celltech shall also permit
Orphan Medical, not more than once per Contract Year and upon thirty (30) days
prior written notice and at reasonable times during normal business hours, to
examine stocks of the Product held by it or its Subdistributors or Sublicensees
to verify compliance with such standards. Orphan Medical shall notify Celltech
in writing of any noncompliance herewith, and Celltech shall use Commercially
Reasonable Efforts to correct the problem and bring such Products into
compliance with applicable standards.

         10.3 Use of Trademark. Celltech shall and shall cause its
Subdistributors and Sublicensees to market the Product under the Trademark;
provided, however that if the Trademark is unavailable or unusable in a
particular country in the Territory, the parties shall mutually agree on a
suitable alternative. In addition, to the extent permitted by applicable law in
each country in the Territory, all labeling for the Product shall bear a legend,
identifying Orphan Medical as the manufacturer of the Product for Celltech.

         10.4 Registration and Approvals. Attached hereto as Appendix B is a
list of the registrations and pending applications for registration for the
Trademark and Patent Rights in the Territory. Orphan Medical shall file
applications and maintain trademark registrations (including for the Trademark
and any alternative trademarks pursuant to Section 10.3) and patent


                                       35
<PAGE>


registrations (including for the Patent Rights) in each country in the Territory
including without limitation the registrations and pending applications for the
Trademark and Patent Rights in each country listed in Appendix B as shall be
reasonably useful or necessary to protect Celltech's rights under this
Agreement; provided, however, that if Orphan Medical shall fail to file a useful
or necessary application or maintain a useful or necessary registration for any
trademarks, alternative trademarks or patents in a country in the Territory, or
to maintain the Trademark and Patent Rights registrations in each country listed
in Appendix B, Celltech shall have the right to file such applications and
maintain such registrations in each such country in the Territory for such
trademarks, alternative trademarks or patents at the expense and in the name and
on behalf of Orphan Medical (or in Celltech's own name if that is not permitted
in the applicable country). Such registration and use of the Trademark and
Patent Rights shall inure to the benefit of and be on behalf of Orphan Medical.
On any termination of this Agreement pursuant to Article XIV hereof, Celltech
shall promptly assign to Orphan Medical registrations and any applications for
registration of trademarks, alternative trademarks or patents for the Product in
the Territory filed in its name pursuant to this Section 10.4.

         10.5 Reservation of Rights. Except as otherwise provided herein, (i)
nothing in this Agreement shall entitle Celltech to any right, title or interest
in or to any of the Patent Rights, Know How, Manufacturing Know How, Trademark,
Improvements, and Proprietary Information of Orphan Medical or any associated
goodwill, which is and shall remain the sole and exclusive property of Orphan
Medical and (ii) Celltech shall not take and shall cause its Subdistributors,
Sublicensees and Third Party manufacturers to not take any action that might (a)
impair any right, title or interest of Orphan Medical in and to the Patent
Rights, Know How, Manufacturing Know How, Trademark, Improvements and
Proprietary Information; or (b) create any right, title or interest in or to
such Patent Rights, Know How, Trademark, Improvements and Proprietary
Information in Celltech or any other Person. Celltech acknowledges Orphan
Medical's proprietary rights as provided in the preceding sentence, and hereby
waives in favor of Orphan Medical any right Celltech may have in and to the
Patent Rights, Know How, Manufacturing Know How, Trademark, Improvements and
Proprietary Information except as herein provided.

                                   ARTICLE XI
                       INTELLECTUAL PROPERTY INFRINGEMENTS

         11.1 Protection of Intellectual Property. Celltech shall cooperate with
Orphan Medical and take all reasonable actions which Orphan Medical may
reasonably request, at Orphan Medical's sole cost and expense, in order to
protect and enforce Orphan Medical's intellectual property rights, including,
but not limited to, carrying out any act Orphan Medical may reasonably require
in connection with any registration, enforcement or protection thereof. Celltech
shall promptly notify Orphan Medical upon becoming aware of any use in the
Territory by a Third Party of the Patent Rights, Know How, Manufacturing Know
How, Trademark, Improvements or Proprietary Information of Orphan Medical
related thereto, or any other Orphan Medical intellectual property relating to
the Product which may constitute an infringement thereof. Orphan Medical shall
have the first right, at its option, to institute proceedings against Third
Party infringers in respect of infringements occurring in the Territory. If
Orphan Medical elects not to institute such proceedings within a period of
thirty (30) days after its discovery of the infringement, Celltech shall have
the right at its option to do so. The party instituting proceedings in the
Territory pursuant to this Article XI shall bring all such


                                       36
<PAGE>


proceedings in the name of both parties. Orphan Medical shall have the exclusive
right in its sole discretion to institute proceedings solely in its name against
Third Party infringers in respect of infringements occurring outside the
Territory. Each party shall cooperate fully with the other party in connection
with any such proceedings against third-party infringers. All expenses of any
such proceedings shall be borne by the party instituting the proceedings and
damages which may be awarded or agreed upon in settlement of such action shall
be allocated first to reimburse the documented costs of the proceedings incurred
by the party bringing suit, with the balance of such amounts, if any, to be
allocated between the parties in accordance with their relative economic loss
from such infringement.

                                  ARTICLE XII
                                  IMPROVEMENTS

         12.1 Improvements by Celltech. Subject to Celltech's rights therein as
provided elsewhere in this Agreement, including without limitation Section 2.2,
Celltech hereby irrevocably assigns, releases, and transfers to Orphan Medical
its entire right, title and interest in and to any Improvement solely relating
to the API and/or Product (whether patentable or not) made or conceived solely
by Celltech employees or contractors.

         12.2 Improvements by Orphan Medical. Subject to Celltech's rights
therein as provided elsewhere in this Agreement, including without limitation
Section 2.2, Orphan Medical shall own all right, title and interest in and to
any Improvement relating to the API and/or Product (whether patentable or not)
made or conceived solely by Orphan Medical employees or by any Orphan Medical
contractor, other than Celltech, including, without limitation, any
manufacturing or analytical process, procedure or method or any source of
synthesis given to Celltech.

         12.3 Disclosure. Celltech shall promptly disclose to Orphan Medical any
and all Improvements relating to the API and/or Product by Celltech's employees
or contractors, either alone or together with Orphan Medical's employees or
contractors. Celltech shall execute at Orphan Medical's expense any assignments,
applications or other instruments or documents reasonably requested by Orphan
Medical to obtain, maintain, and otherwise to perfect Orphan Medical's interest
therein as provided by this Agreement. Celltech's and Orphan Medical's
obligations hereunder shall survive termination of this Agreement.

                                  ARTICLE XIII
                                 CONFIDENTIALITY

         13.1 Proprietary Information. During the Term hereof and for a period
of five (5) years thereafter, any Proprietary Information disclosed by one party
(the "DISCLOSING PARTY"), directly or indirectly, to the other party (the
"RECEIVING PARTY") under this Agreement shall be deemed confidential, and trade
secret information, whether so designated or not, and shall not be disclosed by
the Receiving Party to any Third Party, except as set forth below. Access to
such Proprietary Information shall be limited to employees, agents, consultants
or contractors of the Receiving Party who reasonably require such Proprietary
Information for purposes of performing the Receiving Party's obligations
hereunder and who are bound to the Receiving Party by similar obligations in
respect of confidentiality and use. Such employees, agents, consultants or


                                       37
<PAGE>


contractors shall be advised of the nature and existence of the undertakings in
respect of such Proprietary Information pursuant to this Agreement and of the
applicability of such undertakings to them. The Receiving Party shall use such
Proprietary Information only to carry out its obligations or to exercise its
rights hereunder and shall not use such Proprietary Information for its own
benefit or for the benefit of others or in any way inconsistent with this
Agreement.

         13.2 Exclusions. Information shall not be deemed Proprietary
Information which:

                  (a) at the time of disclosure, is already in the public domain
or thereafter becomes part of the public domain through no act or omission of
the Receiving Party;

                  (b) was rightfully in the possession of the Receiving Party
prior to the time of the disclosure;

                  (c) is independently disclosed to the Receiving Party by a
Third Party who has not violated any confidential obligation owed to the
Disclosing Party;

                  (d) was independently developed by the Receiving Party without
any use of or reliance on any Proprietary Information of the Disclosing Party;

                  (e) is required to be disclosed by legal process, provided
that, in each case the party so disclosing information timely informs the other
and uses its best efforts to limit the disclosure and maintain confidentiality
to the extent possible and permits the other party to attempt by appropriate
legal means to limit such disclosure;

                  (f) is information which is required to be included in patent
applications or required to be provided to the FDA or any other Regulatory
Authority in the Territory in order that Registrations for the Product can be
obtained or otherwise to comply with applicable regulatory requirements;
provided, however, that no Proprietary Information of Celltech or Orphan Medical
shall be disclosed in any such patent application or Registration without the
prior written consent of the Disclosing Party, which consent shall not be
unreasonably withheld; or

                  (g) is information which is required to be disclosed to
customers, users, and prescribers of the Product or which is reasonably
necessary to disclose in connection with the ethical marketing of the Product,
if applicable.

         13.3 Third Party Disclosure. Disclosure by the Receiving Party to a
Third Party shall be made only to the extent necessary to enable the Receiving
Party to comply with its contractual obligations to the Disclosing Party, and
only if such Third Party has executed a confidentiality agreement containing
terms that are at least as protective as the terms of this Agreement.

         13.4 Third Party Confidentiality Agreement. Each Third Party to which
Proprietary Information is disclosed other than a Regulatory Authority shall
agree in writing prior to such disclosure to keep the Proprietary Information in
strict confidence.


                                       38
<PAGE>


         13.5 Confidentiality of Agreement. Except as otherwise required by law,
applicable regulations or the terms of this Agreement or as mutually agreed upon
by the parties hereto, each party shall treat as confidential the terms and
conditions of this Agreement.

         13.6 Prior Confidentiality Agreement. The Confidentiality Disclosure
Agreement between the parties hereto dated 20 November 2002 is hereby superseded
and terminated. Any disclosure of Proprietary Information by either party
pursuant to such Confidentiality Agreement shall be deemed to have been made
hereunder and shall be subject to this Article 13.

                                  ARTICLE XIV
                              TERM AND TERMINATION

         14.1 Term. This Agreement shall become effective as of the Effective
Date and shall remain in full force and effect until the last of Orphan
Medical's Patent Rights to expire or ten (10) years from the date Celltech
receives approval from the EMEA to commercially promote and distribute the
Product, whichever is longer. This Agreement will be automatically extended
indefinitely thereafter unless and until terminated by Celltech upon not less
than twelve (12) months written notice to Orphan Medical. All references herein
to "TERM" or "TERM OF THIS AGREEMENT" shall be deemed to include both the

normal Term as follows:

                  (a) Either party may terminate this Agreement immediately upon
notice if the other party files a petition of any type as to its bankruptcy, is
declared bankrupt, becomes insolvent, makes an assignment for the benefit of
creditors, goes into liquidation or receivership, or otherwise loses legal
control of its business involuntarily.

                  (b) Either party may terminate this Agreement if the other
party materially defaults or commits a material breach of this Agreement and has
failed to cure such default or breach within ninety (90) days of receipt of
written notice thereof from the first party.

                  (c) Either party may terminate this Agreement in accordance
with Section 16.2 or Section 16.3.

uncured for a period of ninety (90) days following receipt of written notice
thereof from Orphan Medical:

                  (a) Celltech shall have failed to meet the applicable minimum
royalty payment requirements for the Product as provided in Article IV hereof.

                  (b) Celltech ceases to sell the Product in the Territory.

                  (c) Celltech alters any Product except as permitted hereunder
or with Orphan Medical's prior written consent.

<PAGE>


                  (d) Except as otherwise herein provided, as to the countries
in which EMEA approval is required for a Registration, if Celltech shall have
failed to obtain a Registration in at least one Major European Country by
December 31, 2006, and as to each other country in the Territory, if Celltech
shall have failed to use Commercially Reasonable Efforts to obtain a
Registration in such country, if, in each case, such failure shall not be due to
a breach by Orphan Medical of its obligations under this Agreement.

         14.4 Rights and Obligations on Termination. In the event of termination
of this Agreement for any reason, the parties shall have the following rights
and obligations:

                           (i) Neither party shall be released from the
                  obligation to make payment of all amounts then or thereafter
                  due and payable in respect of the Term prior to such
                  termination as otherwise herein provided.

                           (ii) Except as provided in Section 14.6, Celltech
                  shall cease to market, promote, sell and distribute the
                  Product and shall return to Orphan Medical, at Celltech's
                  expense, all copies of promotional and technical materials and
                  artwork provided by Orphan Medical; provided, however, that if
                  this Agreement is terminated by Celltech pursuant to Section
                  14.2(b), Orphan Medical shall pay all expenses related to such
                  return of materials and artwork;

                           (iii) Orphan Medical may, if Celltech elects not to
                  pursue its sell-off rights under Section 14.6, repurchase
                  Celltech's inventory of non-obsolete and non-expired Product
                  at the price paid by Celltech for such Product or direct
                  Celltech to sell them to the Third Party or parties selected
                  by Orphan Medical at the price paid by Celltech; provided,
                  however, that if this Agreement is terminated by Celltech
                  pursuant to Section 14.2(b), Orphan Medical must repurchase
                  such inventory at the price paid by Celltech if Celltech
                  elects not to pursue its sell-off rights under Section 14.6;

                           (iv) Celltech shall return or, if requested by Orphan
                  Medical, destroy all of Orphan Medical's Proprietary
                  Information, including, if applicable, all electronic copies
                  thereof and shall certify in writing that it has done so; and

                           (v) Celltech shall comply with the provisions of
                  Section 10.4 regarding the assignment to Orphan Medical of
                  trademark and/or patent rights registrations filed in
                  Celltech's name.

         14.5 Partial Termination. In the event that a cause of termination
shall relate solely to any country not subject to regulation by the EMEA, then
termination of this Agreement shall be limited and applied only to such country
or portion of the Territory.

         14.6 Sell-Off Period. Notwithstanding anything to the contrary in
Section 14.4 hereto, upon expiration or termination of this Agreement, Celltech
shall have the right to continue to distribute its existing inventory of
non-expired Product for a period of six (6) months after the effective date of
expiration or the effective date of termination of this Agreement as the case
may be. Any such continued distribution shall be in accordance with all
applicable laws and regulations and the terms of this Agreement.

         14.7 Survival. The provisions of Articles I (Definitions), VIII
(Representations & Warranties), IX (Indemnification), XIII (Confidentiality),

as the provisions of Articles III (Compliance with Laws and Regulations), XI
(Intellectual Property Infringement), XII (Improvements) Article XIII

intended to survive the expiration or termination of this Agreement (including
without limitation, Sections 3.4 (Return of Initial Payment), Section 4.8 (Books
and Records) and Section 7.3(e) (Consignment of Product - Return of Consignment
Inventory) shall survive any termination or expiration of this Agreement.

         14.8 Assignment of Authorizations. As soon as possible following the
expiration or earlier termination of this Agreement, Celltech shall take all
necessary steps to ensure expeditious assignment of all Marketing Authorizations
and Orphan Drug Designations which are in Celltech's name to Orphan Medical. If
an assignment to Orphan Medical is prohibited under the laws of a country in the
Territory, Celltech agrees to and hereby grants Orphan Medical authorization to
distribute the Product under such Marketing Authorization until Orphan Medical
or its designee has obtained Marketing Authorizations and Orphan Drug
Designations in its own name for the Product in that country; provided that
Orphan Medical shall defend, indemnify and hold harmless Celltech from and
against all Claims and Indemnification Amounts of whatsoever kind or nature that
result from, arise out of or relate to Orphan Medical's distribution of the
Product under the Marketing Authorizations and Drug Designations continuing in
Celltech's name as contemplated by this Section 14.8.

         14.9 Rights on Termination for Cause. In the event of termination of
this Agreement by Orphan Medical pursuant to the provisions of Sections 14.2(a)

expense to Orphan Medical, its then current list of prospects and customers,
including company name, contact, address and telephone number.

         14.10 No Compensation. In the event of any expiration or termination of
this Agreement for any reason, neither party shall owe any compensation to the
other party for lost profits, lost opportunities, good will, or any other loss
or damage in respect of future periods as a result of or arising from such
termination or expiration.

                                   ARTICLE XV
                                   ARBITRATION

         15.1 Litigation Rights Reserved. If any dispute arises with respect to
the unauthorized use of Proprietary Information by either Party or, Orphan
Medical's Trademark, Patent Rights, Know How, Manufacturing Know How, and
Improvements by Celltech, or with respect to acts or omissions of Celltech or
Orphan Medical relating to the Product which in the good faith discretion of
Orphan Medical or Celltech, as the case may be, negatively impact the safety of
the public, Orphan Medical or Celltech, as the case may be, may seek any
available equitable remedy from a court of competent jurisdiction.

         15.2 Arbitration. Except as provided in Sections 7.13 and 15.1, all
disputes arising between the parties in connection with this Agreement shall be
settled through friendly


                                       41
<PAGE>


consultations between the parties and if no agreement can be reached through
consultations, they shall be submitted to arbitration for settlement. The
arbitration shall take place in New York, New York, and be conducted by the
American Arbitration Association in accordance with the commercial arbitration
rules thereof (the "RULES") except as modified hereby. All necessary
determinations, including the arbitration decision, shall be made by a panel of
three arbitrators (the "PANEL"). Within ten (10) days after delivery of a notice
of arbitration, each of the two parties shall select one arbitrator as a member
of the Panel. The two parties shall select as the third member of the Panel an
independent arbitrator with no past or current business affiliations with either
party, and if the parties cannot agree on such independent arbitrator within ten
(10) days after delivery of a notice of arbitration, such independent arbitrator
shall be selected in accordance with the Rules. The Panel shall establish a
schedule of discovery and hearing such that the Panel's final written decision
shall be issued within one hundred and twenty (120) days after selection of the
independent arbitrator serving on the Panel. Each party must produce all
relevant non-privileged documents requested by the other party within thirty
(30) days after the request therefor. The Panel's decision must be in writing
and shall set forth the reasons therefor. Such decision shall be conclusive
determination of the matter and binding on the parties, shall have the effect of
an arbitration award, and shall not (to the extent permitted by applicable law)
be contested by any of them. The fees and expenses of an arbitrator selected by
a party shall be borne by such party. The fees and expenses of the third
independent arbitrator shall initially be borne equally by the parties, and
shall be allocated between the parties in accordance with the final decision of
the Panel, which decision shall allocate such fees between the parties as
determined by the Panel.

         15.3 Governing Law. This Agreement shall be governed by, and
interpreted and construed in accordance with, the laws of the State of New York,
U.S.A., excluding (i) its choice of law rules and (ii) the United Nations
Convention on the International Sale of Goods, provided that (x) enforcement and
operation of the Consignment Inventory arrangements in Section 7.3 shall be
governed by the laws of England, and (y) enforcement and operation of the
arbitration agreement contained in Section 15.2 hereof, and the enforcement of
any award rendered pursuant thereto, shall be governed by United States federal
law to the exclusion of State law.

                                  ARTICLE XVI
                                  FORCE MAJEURE

         16.1 Events of Force Majeure. Anything in this Agreement to the
contrary notwithstanding, neither party shall be liable or responsible for any
failure or delay in performance (excluding payment of sums owed hereunder) due
to causes affecting such party and, in the case of Orphan Medical, its
designated suppliers, and, in the case of Celltech, its Subdistributors,
Sublicensees and Third Party manufacturers, beyond the reasonable control of
such party, including, without limitation, any act of God; regulation or law of
any government or an agency thereof, excluding, however, if a Regulatory
Authority enjoins manufacture of the Product or otherwise closes the Product
manufacturing facilities due to Orphan Medical's failure to comply with cGMP or
any other breach by Orphan Medical of its obligations under this Agreement; war;
terrorism; insurrection or civil commotion; earthquake, tornado, fire, flood or
storm; epidemic; or failure of public utilities or common carriers. Such excuse
shall continue as long as the condition preventing the performance continues.
Upon cessation of such condition, such party shall promptly resume performance
hereunder.


                                       42
<PAGE>


         16.2 Notice. A party affected by an event of force majeure shall give
the other party prompt written notice of the occurrence of any event of force
majeure and the nature and duration thereof. An affected party shall use all
Commercially Reasonable Efforts to resume performance as quickly as possible and
to give the other party prompt written notice when it is again fully able to
perform such obligations. If such event of force majeure continues for more than
one hundred eighty (180) days, either party may terminate this Agreement by
giving ten (10) days written notice to the other party. If Celltech is the
affected party, such notice of resumption of performance shall state the
quantities of Product Orphan Medical needs to ship to enable Celltech to resume
performance of obligations.

         16.3 Hardship. In the event that, during the Term, any law or
government-enacted regulation or decree renders the performance by either party
of its respective obligations hereunder unduly onerous or infeasible to
implement, Celltech and Orphan Medical shall consult each other and show mutual
understanding with a view to making such adjustments as would appear to be
necessary and feasible. The party who considers that the change in regulation or
decree is unduly onerous or infeasible to implement, shall notify the other
within ninety (90) days of the change in regulation or decree, specifying the
specific date and change, an evaluation of the hardship which is or shall be
suffered and the proposal made by it to remedy that change if feasible. If the
parties fail to reach an agreement within ninety (90) days after the date of the
notice, either party shall at any time thereafter be entitled to terminate this
Agreement upon written notice only with respect to the country or countries
affected by such change in regulation or decree.

courier service or (c) facsimile transmission with electronic confirmation of
receipt. Notices so given shall be effective (1) upon receipt by the party to
whom notice is given, or (2) on the tenth (10th) day following international
mailing, as may be the case, whichever occurs first.

         17.2 Waiver. No failure by either party to take any action or assert
any right hereunder shall be deemed to be a waiver of such right in the event of
the continuation or repetition of the circumstances giving rise to such right.

         17.3 Entire Agreement. This Agreement and the Schedules and Appendices
hereto constitute the entire agreement of the parties with respect to the
subject matter hereof, and supersede all previous agreements by and between the
parties as well as all proposals, oral or written, and all negotiations,
conversations or discussions heretofore had between the parties related to this
Agreement.

         17.4 Amendment. No modification or amendment of this Agreement shall be
binding unless in writing and signed by both parties.

         17.5 Headings. Article, section and paragraph headings used in this
Agreement are for convenience only, have no legal significance, and in no way
change the construction or meanings of the terms hereof.

         17.6 Relationship of the Parties. The parties shall be deemed
independent contractors of each other and, as such, they shall not be entitled
to any benefits applicable to employees of the other party. Nothing contained in
this Agreement shall be construed or implied to create an agency, partnership,
or employer and employee relationship between Orphan Medical and Celltech. At no
time shall one party make commitments or incur any charges or expenses for or in
the name of the other party except as specifically provided herein.

         17.7 Assignment. Neither party may assign this Agreement without the
prior written consent of the other party except that either Orphan Medical or
Celltech may assign this Agreement (a) to an Affiliate or (b) in connection with
a merger, stock sale, or the sale or transfer of all or substantially all of the
assets of such party or the division of such party manufacturing or marketing
the Product, as the case may be, provided, however, any permitted assignee shall
assume all obligations of its assignor under this Agreement and in the case of
clause (a), the assigning party shall remain primarily liable for the
performance of such Affiliate. Any purported assignment in violation of the
foregoing sentence shall be null and void. No assignment shall relieve either
party of responsibility for the performance of any accrued obligation under this
Agreement. Subject to the foregoing, this Agreement shall be binding upon and
inure to the benefit of the permitted successors or permitted assigns of
Celltech and Orphan Medical, respectively.

         17.8 Severability. If any term or condition of this Agreement is found
by a court of competent jurisdiction to violate the provisions of any applicable
statute, law or regulation, the remainder of this Agreement shall remain in full
force and effect. The parties shall then negotiate in good faith to modify this
Agreement, to the extent necessary to make the affected term or condition of
this Agreement valid and enforceable, having full regard for the original intent
of the parties.


                                       44

         17.9 Publicity. This Agreement is confidential and neither party shall
issue press releases or engage in other types of publicity of any nature
(whether written or oral) dealing with the existence or details of this
Agreement without the other party's prior written approval, which approval shall
not be unreasonably withheld; provided that, approval of such disclosure shall
be deemed to be given to the extent such disclosure is required to comply with
governmental rules, regulations or requirements. In such event, the disclosing
party shall furnish a copy of such disclosure to the other party.

         17.10 Counterparts. This Agreement may be executed in one or more
counterparts, each of which shall be deemed to be an original, and all of which
together shall constitute one and the same Agreement. This Agreement may be
executed and delivered via facsimile transmission with the same force and effect
as if it were executed and delivered in writing. In making proof of this
Agreement, it shall not be necessary to produce or account for more than one
fully executed counterpart.

         17.11 LIMITATION OF DAMAGES. NEITHER ORPHAN MEDICAL NOR CELLTECH SHALL
HAVE ANY LIABILITY OF ANY KIND TO THE OTHER PARTY FOR ANY SPECIAL, INDIRECT,
INCIDENTAL OR CONSEQUENTIAL LOSSES OR DAMAGES, EVEN IF ORPHAN MEDICAL OR
CELLTECH, AS THE CASE MAY BE, SHALL HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH
POTENTIAL LOSS OR DAMAGE BY THE OTHER PARTY. FOR PURPOSES OF THE LIMITATION OF
LIABILITY IN THE IMMEDIATELY PRECEDING SENTENCE, (i) LEGAL FEES AND EXPENSES
THAT ARE RECOVERABLE AS PROVIDED IN ARTICLE IX SHALL NOT BE CONSIDERED INDIRECT
DAMAGES, (ii) INDIRECT DAMAGES PAYABLE BY AN INDEMNIFIED PARTY TO A THIRD PARTY
THAT WOULD BE RECOVERABLE UNDER THE INDEMNITY PROVISIONS IN ARTICLE IX BUT FOR
SUCH LIMITATION OF LIABILITY SHALL BE RECOVERABLE NOTWITHSTANDING SAID
LIMITATION OF LIABILITY AND (III) LOST PROFITS SHALL NOT BE DEEMED TO BE
SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES EXCEPT IN RESPECT OF FUTURE PERIODS

                                   APPENDIX D
            STANDARD OPERATING PROCEDURE FOR EXCHANGE OF SAFETY DATA

         The Orphan Medical and Celltech individuals in charge of
pharmacovigilance shall follow the procedure outlined below in reporting adverse
experiences.

         1. Definitions. Definitions shall be those in use by the International
Conference on Harmonization (ICH) as may be amended by ICH from time to time.
Current definitions are:

                  1.1. Adverse Event ("AE") means any untoward medical
occurrence in a patient or clinical investigation subject administered a
pharmaceutical product and which does not necessarily have to have a causal
relationship with this treatment. An AE can therefore be any unfavorable and
unintended sign (including an abnormal laboratory finding), symptom, or disease
temporarily associated with the use of a medicinal (investigational) product,
whether or not related to the medicinal (investigational) product.

                  1.2. Serious Adverse Event ("SAE") means any untoward medical
occurrence that at any dose:

                           o        results in death,

                           o        is life-threatening,

                           o        requires inpatient hospitalization or
                                    prolongation of existing hospitalization,

                           o        results in persistent or significant
                                    disability/incapacity, or

                           o        results in a congenital anomaly/birth
                                    defect.

                  1.3. Adverse Drug Reaction ("ADR")

                           o        ADRs in the clinical setting refer to all
                                    noxious and unintended responses to a
                                    medicinal product (i.e., where the
