association with which AMICUS or an AFFILIATED COMPANY has any agreement,
understanding or arrangement with respect to consideration (such as, among other
things, an option to purchase stock or actual stock ownership, or an arrangement
involving division of profits or special rebates or allowances), the royalties
to be paid hereunder for any such LICENSED PRODUCT shall be based upon the
greater of: 1) the net selling price at which the purchaser of LICENSED PRODUCTS
resells such products to the end user, 2) the fair market value of the LICENSED
PRODUCT which shall be determined based on the sales price of similar products
or services sold in the market, as applicable, or as may be mutually agreed by
the parties, or 3) the net selling price of LICENSED PRODUCTS paid to AMICUS or
an AFFILIATED COMPANY.

COMPANY is for the purpose of investment.

     3.8 FOREIGN CURRENCY. To the extent NET SALES of Licensed Products
manufactured in the United States are made by AMICUS or a SUBLICENSEE in a
foreign country, any royalties due to UMBC based thereon shall be first
determined in the currency of the country in which the royalties were earned and
then converted to their equivalent in United States Dollars using an average of
the currency exchange rates quoted in the Wall Street Journal for the last
business day of each of the three (3) consecutive calendar months constituting
the calendar quarter in which the royalties were earned. To the extent that
statutes, laws, codes, or government regulations (including currency exchange
regulations) shall prevent or limit royalty payments by AMICUS or its
SUBLICENSEES in any country, all monies due to UMBC shall promptly be deposited
by AMICUS or its SUBLICENSEE, as the case may be, in an account in a local bank
in such country, said bank to be designated by UMBC in writing; or paid to UMBC,
or deposited in its account, in any other country where such payment or deposit
is lawful under the currency restrictions, as directed in writing by UMBC.

     3.9 LATE PAYMENTS. In the event that any payment due hereunder is not made
when due, the payment shall accrue interest beginning on the tenth day following
the due date thereof, calculated at the annual rate of the sum of (a) two

on the date said payment is due, the interest being compounded on the last day
of each calendar quarter, provided however, that in no event shall said annual
interest rate exceed the maximum legal interest rate for corporations. Each such
payment when made shall be accompanied by all interest so accrued. Said interest
and the payment and acceptance thereof shall not negate or waive the right of
UMBC to seek any other remedy, legal or

equitable, to which it may be entitled because of the delinquency of any payment
including, but not limited to termination of this Agreement as set forth in
Paragraph 9.2.

     ARTICLE IV - PATENT PROSECUTION, MAINTENANCE, & INFRINGEMENT

     4.1 PROSECUTION & MAINTENANCE. UMBC, at AMICUS' expense, shall maintain all
patents specified under PATENT RIGHTS upon authorization of AMICUS and AMICUS
shall be licensed thereunder. Title to all such patents and patent applications
shall reside in UMBC. UMBC shall have full and complete control over all patent
matters related to the PATENT RIGHTS, provided however, that UMBC will consider
and incorporate reasonable comments received from AMICUS. AMICUS will provide
payment authorization to UMBC at least one (1) month before an action is due,
provided that AMICUS has received timely notice of such action from UMBC and has
the opportunity to provide comments. Failure to provide authorization can be
considered by UMBC as an AMICUS decision not to authorize an action.

     4.2 NOTIFICATION. Each party will notify the other promptly in writing when
any infringement of the PATENT RIGHTS by another is uncovered or suspected.

     4.3 INFRINGEMENT. AMICUS shall have the first right to enforce any patent
within PATENT RIGHTS in the FIELD against any infringement or alleged
infringement thereof, and shall at all times keep UMBC informed as to the status
thereof. AMICUS may, in its sole judgment and at its own expense, institute suit
against any such infringer or alleged infringer and control, settle, and defend
such suit in a manner consistent with the terms and provisions hereof and
recover, for its account subject to Paragraph 4.4, any damages, awards or
settlements resulting therefrom. This right to sue for infringement shall not be
used in an arbitrary or capricious manner. UMBC shall reasonably cooperate in
any such litigation, including being joined as a party plaintiff if AMICUS'
attorneys, in their sole discretion, determine that UMBC is necessary to any

such litigation, at AMICUS' expense using AMICUS' counsel of choice. UMBC shall
have the right to retain counsel of its own selection, at UMBC's expense, in any
litigation instituted by AMICUS pursuant to this Paragraph 4.3, provided that
AMICUS' counsel shall be lead counsel.

     If AMICUS elects not to enforce any patent within the PATENT RIGHTS, then
it shall so notify UMBC in writing within ninety (90) days of receiving notice
that an infringement exists, and UMBC may, in its sole judgment and at its own
expense, take steps to enforce any patent and control, settle, and defend such
suit in a manner consistent with the terms and provisions hereof, and recover,
for its own account, any damages, awards or settlements resulting therefrom.
UMBC shall reasonably consider any comments from AMICUS regarding any settlement
that may impair AMICUS' rights under this Agreement in any way prior to UMBC
entering into such settlement. AMICUS shall have the right to participate in
such litigation and, if it elects to do so, will retain counsel of its own
selection and at its expense, provided that UMBC's counsel shall be lead
counsel.

     4.4 RECOVERY. Any recovery by AMICUS under Paragraph 4.3 shall be deemed to
reflect loss of commercial sales, and AMICUS shall pay to UMBC a percent,
according to the rate determined for Sublicense Consideration as described in
Paragraph 3.5, of the recovery net of all reasonable costs and expenses
associated with each suit or settlement. If the cost and expenses exceed the
recovery, then one-half (1/2) of the excess shall be credited against royalties
payable by AMICUS to UMBC hereunder in connection with sales in the country of
such legal proceedings, provided, however, that any such credit under this
Paragraph shall not exceed fifty percent (50%) of the royalties otherwise
payable to UMBC with regard to sales in the country of such action in any one
calendar year, with any excess credit being carried forward to future calendar
years.

Inventors and students who were involved with the creation of the inventions
covered by the PATENT RIGHTS, as applicable, harmless as against any judgments,
fees, expenses, or other costs arising from or incidental to any product
liability or other lawsuit, claim, demand or other action brought as a
consequence of the practice of said inventions by any of the foregoing entities,
whether or not UMBC or said Inventors, either jointly or severally, is named as
a party defendant in any such lawsuit. Practice of the inventions covered by the

party on behalf of or for the account of AMICUS or by a third party who
purchases LICENSED PRODUCTS from AMICUS, an AFFILIATED COMPANY, or a
SUBLICENSEE, shall be considered AMICUS' practice of said inventions for
purposes of this Paragraph. The obligation of AMICUS to defend, indemnify, and
hold harmless, as set forth in this Paragraph, shall survive the termination of
this Agreement.

     7.2 INDEMNIFICATION BY UMBC. UMBC will indemnify and hold AMICUS harmless
from any and all losses, claims, liabilities, damages, costs and expenses
(including reasonable attorney's fees) which arise out of the acts or omissions
of the University, its agents, employees or students in connection with this
Agreement or by any breach or default in the performance of the obligations of
the University hereunder. The obligations of UMBC pursuant to this Paragraph 7.2
are contingent upon the existence of an appropriation to UMBC by the State
Legislature for the purpose of satisfying this clause in particular or clauses
of this type, in general at the time that the acts or omissions giving rise to
the University's obligations occur. If UMBC has no such appropriation at the
time such acts or omissions occur, it will seek an appropriation to satisfy
claims pursuant to this subsection, but its obligations to pay AMICUS will be
subject to the receipt of such an appropriation.

                         ARTICLE VIII - CONFIDENTIALITY

     8.1 CONFIDENTIALITY. In performing under this Agreement, the parties may
exchange information that they consider to be confidential. The recipient of
such information agrees to accept the disclosure of said information which is
(a) marked as confidential at the time it is sent to the recipient, or (b)
orally, is stated by the disclosing party to be confidential, or (c) is of such
a nature that the receiving party in the exercise of reasonable business
judgment should know is confidential, and to employ all reasonable efforts to
maintain the information secret and confidential, such efforts to be no less
than the degree of care employed by the recipient to preserve and safeguard its
own confidential information. The information shall not be disclosed or revealed
to anyone except employees and consultants of the recipient who have a need to
know the information and who have entered into a secrecy agreement with the
recipient under which such employees and consultants are required to maintain
confidential the proprietary information of the recipient and such employees and
consultants shall be advised by the recipient of the confidential nature of the
information and that the information shall be treated accordingly; provided
however, a receiving party may disclose confidential information to its
accountants, banks, financing sources, financial officers, lawyers, and related
professionals or such other persons having a legitimate need to know such
information, or as otherwise permitted by the disclosing party, provided that
such individuals are under an obligation to keep such information confidential.

     The obligations of this Paragraph shall also apply to the confidential
information of AFFILIATED COMPANIES and/or SUBLICENSEES provided by AMICUS to
UMBC. UMBC's, AMICUS', and its AFFILIATED COMPANIES' obligations under this
Paragraph shall extend until three (3) years after the termination of this
Agreement.

               publicly known and readily available to the trade or the public
               prior to the date of the disclosure; or

          B.   that can be demonstrated from written records to have been in the
               recipient's possession or readily available to the recipient from
               another source not under obligation of secrecy to the disclosing

               by or for the receiving party without reference to confidential
               information disclosed by the disclosing party.

     8.3 COMPLIANCE WITH LAW. The prohibitions on the disclosure of confidential
information of a disclosing party under this Agreement shall not preclude a
receiving party, on the advice of counsel, from complying with applicable law or
other demand under lawful process, including a discovery request in a civil
litigation, so long as the receiving party first gives the disclosing party
written notice of the required disclosure and reasonably cooperates with the
disclosing party, at the disclosing party's sole expense, in seeking reasonable
protective arrangements with respect to such confidential information. In no
event shall the receiving party's cooperation with the disclosing party require
the receiving party to take any action that, on the advice of their counsel,
could result in the imposition of any sanctions or other penalties against it.

     8.4 RIGHT TO PUBLISH. Each party may publish manuscripts, abstracts or the
like describing the PATENT RIGHTS and inventions contained therein provided

confidential information of the other as defined in Paragraph 8.1, is not
included without first obtaining approval from the disclosing party to include
such confidential information. Otherwise, either party shall be free to publish
manuscripts and abstracts or the like related to the PATENT RIGHTS without the
other party's prior approval.

                         ARTICLE IX - TERM & TERMINATION

     9.1 TERM. The term of this Agreement shall commence on the EFFECTIVE DATE
and shall continue until the date of expiration of the patent included within
PATENT RIGHTS.

     9.2 TERMINATION BY EITHER PARTY. This Agreement may be terminated by either
party, in the event that the other party (a) becomes insolvent or seeks
protection under any bankruptcy, receivership, trust deed, creditors
arrangement, composition or comparable proceeding, or if any such proceeding is
instituted against a party and not dismissed within fourteen (14) days, or (b)
fails to perform or otherwise breaches any of its obligations hereunder, if,
following the giving of notice by the terminating party of its intent to
terminate and stating the grounds therefore, the party receiving such notice
shall not have cured the failure or breach within thirty (30) days. In no event,
however, shall such notice or intention to terminate be deemed to waive any
rights to damages or any other remedy that the party giving notice of breach may
have as a consequence of such failure or breach.

     9.3 TERMINATION BY AMICUS. Notwithstanding termination pursuant to
Paragraph 9.2, above, AMICUS may terminate this Agreement and the license
granted herein, for any reason, upon giving UMBC sixty (60) days written notice.

terminated, both parties shall be released from all obligations and duties
imposed or assumed hereunder to the extent so terminated, except as expressly

contrary in this Agreement. Upon termination, both parties shall cease any
further use of the confidential information disclosed to the receiving party by
the other party. This obligation extends as well to any other persons to whom a
party has disclosed confidential information of the other. Termination of this
Agreement, for whatever reason, shall not affect the obligation of either party
to make any payments for which it is liable prior to or upon such termination.
Termination shall not affect UMBC's right to recover unpaid royalties or fees or
reimbursement for patent expenses incurred pursuant to Paragraph 4.1 prior to
termination. At the end of the Sell-Off Period (defined below), AMICUS shall
submit a final royalty report to UMBC (which UMBC shall treat as confidential
information of AMICUS) and any royalty payments and unreimbursed patent expenses
due UMBC shall become immediately due and payable. Upon termination of this
Agreement, all rights in and to the PATENT RIGHTS shall revert immediately to
UMBC at no cost to UMBC; provided, however, that if this Agreement is terminated
pursuant to Paragraphs 9.2 or 9.3, AMICUS, its AFFILIATED COMPANIES and/or
SUBLICENSEES, shall have the right to continue to manufacture LICENSED PRODUCTS
to the extent AMICUS, its AFFILIATED COMPANIES and/or SUBLICENSEES, have parts,
components, or supplies on hand or on order, and to sell LICENSED PRODUCTS
already in inventory at the time of such termination ("Sell-Off Period"),
provided that the Sell-Off Period shall not exceed a period of one (1) year, and
subject to the royalty payment obligations of Paragraph 3.3, the reporting
provisions of Paragraph 5.1, and any other obligations that survive as set forth
in Paragraph 10.13. In the event of termination of this Agreement, AMICUS shall
provide all of its SUBLICENSEES with written notice of: (i) termination of this
Agreement; (ii) termination of all sublicenses under this Agreement; and (iii)
the right of any SUBLICENSEES to negotiate a license to PATENT RIGHTS directly
with UMBC. A copy of all such notices shall be provided to UMBC, and treated as
confidential information of AMICUS.

                            ARTICLE X - MISCELLANEOUS

     10.1 USE OF NAME. AMICUS shall not use the name of UMBC or The University
System of Maryland or any of its constituent parts, or any contraction thereof
or the name of the Inventors in any advertising, promotional, sales literature
or fundraising documents without prior written notice to UMBC. AMICUS shall
allow at least seven (7) business days notice of any proposed public disclosure
for UMBC's review and approval. If UMBC does not respond by the end of said
seven day period, any proposed use of the names contemplated herein shall be
deemed approved provided, however, that UMBC's name shall not be used in any
case as an endorsement of LICENSED PRODUCTS.

     10.2 NO PARTNERSHIP. Nothing in this Agreement shall be construed to create
any agency, employment, partnership, joint venture or similar relationship
between the parties other than that of a licensor/licensee. Neither party shall
have any right or authority whatsoever to incur any liability or obligation
(express or implied) or otherwise act in any manner in the name or on the behalf
of the other, or to make any promise, warranty or representation binding on the
other.

     10.3 NOTICE OF CLAIM. Each party shall give the other or its representative
immediate notice of any suit or action filed, or prompt notice of any claim
made, against them arising out of the performance of this Agreement.

     10.4 PRODUCT LIABILITY. Prior to initial human testing or first commercial
sale of any LICENSED PRODUCT, as the case may be, in any particular country,
AMICUS shall establish and maintain, in each country in which AMICUS, an
AFFILIATED COMPANY or a SUBLICENSEE shall test or sell a LICENSED PRODUCT,
product liability or other appropriate insurance coverage appropriate to the
risks involved in marketing LICENSED PRODUCTS; provided however, such insurance
shall include coverage of at least one million dollars ($1,000,000) per

request, UMBC agrees to reasonably consider agreeing to insurance coverage of
less than one million dollars ($1,000,000) subject to AMICUS ability to provide
evidence that a lesser amount of coverage is usual, customary, and sufficient to
cover product liability risk for LICENSED PRODUCTS or comparable products in the
industry. Upon UMBC's request, AMICUS will furnish UMBC with a Certificate of
Insurance for each product liability insurance policy obtained, which shall be
treated as confidential information of AMICUS. UMBC shall be listed as an
additional insured in AMICUS' said insurance policies. If such product liability
insurance is underwritten on a 'claims made' basis, AMICUS agrees that any
change in underwriters during the term of this Agreement will require the
purchase of 'prior acts' coverage to ensure that coverage will be continuous
throughout the term of this Agreement.

     10.5 GOVERNING LAW. This Agreement shall be construed, and legal relations
between the parties hereto shall be determined, in accordance with the laws of
the State of Maryland applicable to contracts solely executed and wholly to be
performed within the State of Maryland without giving effect to the principles
of conflicts of laws. Any disputes between the parties to the Agreement shall be
brought in the state or federal courts of Maryland.

     10.6 NOTICE. All notices or communication required or permitted to be given
by either party hereunder shall be deemed sufficiently given if mailed by
registered mail or certified mail or sent by overnight courier, such as Federal
Express, to the other party at its respective address set forth below or to such
other address as one party shall give notice of to the other from time to time
hereunder. Mailed notices shall be deemed received on the third business day
following the date of mailing. Notices sent by overnight courier shall be deemed
received the following business day. Notices may be sent by facsimile provided
that any notice sent by facsimile is confirmed by registered mail or certified
mail or sent by overnight courier. Notices received by facsimile shall be deemed
received on the day either party receives such a facsimile at the number listed
below.

                      FIRST AMENDMENT TO LICENSE AGREEMENT

         This Amendment having an effective date as of March 31, 2007, is made
by and between AMICUS THERAPEUTICS, INC., a Delaware corporation having a
principal place of business at 6 Cedar Brook Drive, Cranbury, New Jersey 08512
(hereinafter "AMICUS") and UNIVERSITY OF MARYLAND, BALTIMORE COUNTY, having an
address of 1000 Hilltop Circle, Baltimore, Maryland 21250, a constituent
institution of the University System of Maryland, which is an agency of the
State of Maryland (hereinafter "UMBC").

         WHEREAS, UMBC and AMICUS entered into a license agreement dated
June 26, 2003 (hereinafter the "Agreement"); and

         WHEREAS, UMBC and AMICUS find it in their mutual best interests to
amend said Agreement to broaden the "Licensed Field" to include all human
therapeutics; and

          NOW THEREFORE; the parties hereto agree as follows:

 1.      PARAGRAPH 1.6 SHALL BE REVISED TO READ AS FOLLOWS:

         "LICENSED FIELD" shall mean the prevention or treatment of any human
         disease, indication or clinical condition.

 2.      PARAGRAPH 3.4, SUBPARAGRAPHS 1) AND 2) SHALL BE REPLACED WITH THE
         FOLLOWING:

         1)   [***] the first demonstration of safety and efficacy of a LICENSED
              PRODUCT over a dosing interval of greater than 28 days in a human
              phase II clinical trial for each disease, indication or clinical
              condition and

         2)   [***] upon receiving marketing approval from the U.S. Food and
              Drug Administration  for a LICENSED PRODUCT for each disease,
              indication, or clinical condition.

         The remaining paragraph of Paragraph 3.4 to the License Agreement shall
         remain in effect.

 3.      ADD TO THE END OF PARAGRAPH 5.3 THE FOLLOWING:

         AMICUS shall also exercise commercially reasonable efforts to develop
         other LICENSED PRODUCTS suitable for different markets, so that the
         PATENT RIGHTS can be commercialized as broadly and as speedily as good
         scientific and business judgment would deem possible.

TREATMENT HAS BEEN REQUESTED. ALL SUCH OMITTED MATERIAL HAS BEEN FILED WITH THE
SECURITIES AND EXCHANGE COMMISSION PURSUANT TO RULE 24b-2 PROMULGATED UNDER THE
SECURITIES EXCHANGE ACT OF 1934, AS AMENDED.
<PAGE>
4.       ADD THE FOLLOWING AS PARAGRAPH 5.5:

         OTHER PRODUCTS. In the event that evidence is provided, in writing by
         UMBC or by another party, to AMICUS, demonstrating the practicality of
         a particular market which is not being developed or commercialized by
         AMICUS; AMICUS shall either provide UMBC with a reasonable development
         plan and start development or attempt to reasonably sublicense the
         particular technology to a third party. If within six (6) months of
         such notification by UMBC, AMICUS has not initiated such development
         efforts or sublicensed that particular market, UMBC may terminate this
         license for such particular market. This Paragraph shall not be
         applicable if AMICUS reasonably demonstrates to UMBC that
         commercializing such additional LICENSED PRODUCTS or granting such a
         sublicense in said particular market would have a potentially adverse
         commercial effect upon marketing or sales of the LICENSED PRODUCTS
         developed and being sold by AMICUS or its SUBLICENSEES.

5.       In consideration for UMBC agreeing to amend the Agreement, AMICUS
         agrees to pay UMBC [***] as a non-refundable licensing fee, which shall
         not be creditable against future royalties or other fees due to UMBC
         pursuant to the Agreement. Said licensing fee shall be due within
         thirty (30) days of the effective date of this Amendment.

6.       All other terms and conditions of the Agreement shall remain in full
         force and effect.

IN WITNESS WHEREOF, the parties hereto have caused this Amendment to be executed
the day and year first written above.

          power to direct the management and policies of such non-corporate
          entities.

     2.1.2 "Agreement" shall mean this Exclusive License Agreement including its
          appendices.

     2.1.3 "Analogue" shall mean any chemical structure that is a structural
          homolog to, or derived from, the Compound and is covered by NOVO
          NORDISK Intellectual Property Rights.

     2.1.4 "Annual Net Sales" means the gross invoice price of the Licensed
          Product per year sold by AMICUS THERAPEUTICS, its Affiliates or
          sublicensees to independent Third Party customers in bona fide
          arms-length transactions, less the following deductions:

          (a)  trade, cash and/or quantity discounts actually taken;

          For Annual Net Sales of a Licensed Product sold or supplied as a
          Combination, the Annual Net Sales of such a Combination in a country
          shall be determined as follows:

          A) by multiplying the Annual Net Sales of the Combination by the
          fraction A/(A+B), where A is the invoice price of the Licensed Product
          in that country if sold separately and B is the total invoice price of
          any other active component or components in the Combination in that
          country if sold separately; or If the Licensed Product and the other
          active component or components in the Combination are not sold
          separately, the Annual Net Sales, for purposes of determining
          royalties on the Combination, will be calculated by multiplying the
          Annual Net Sales of the Combination by the fraction determined by
          mutual agreement of the Parties, that reflects the relative
          contribution in value that the Licensed Product contained in the
          Combination makes to the total value of such Combination to the end
          user.; and

          B) if the Licensed Product contained in the Combination is not sold in

          as a pharmaceutical product containing, in addition to the Licensed
          Product, one or more biologically active pharmaceuticals which are not

     Notwithstanding the foregoing, if (a) AMICUS THERAPEUTICS and/or its
     Affiliates (and/or appertaining sublicensees, as the case may be) is
     required to obtain from any Third Party that is not an Affiliate or a

     (including, without limitation, attorneys' fees, but excluding any
     judgments or any settlements in connection with such claims) incurred by
     AMICUS THERAPEUTICS and/or its Affiliates (and/or appertaining
     sublicensees, as the case may be) in connection with any such infringement
     claim against the running royalty for the subject Licensed Products, in the
     appertaining country(ies) during the appertaining time period. However, not
     withstanding the above the minimum royalty payable by AMICUS THERAPEUTICS
     and its Affiliates and sublicensees to NOVO NORDISK shall never be reduced
     below [***] of the royalties set forth in this Article 3.4, Table 1 and
     which are payable for Licensed Product in the specific country or countries
     in question.

3.5  All payments required under this Agreement shall be made in US Dollars to
     the following bank account or to such account as NOVO NORDISK may, from
     time to time, notify AMICUS THERAPEUTICS in writing:

     Danske Bank,
     Copenhagen
     Account number: [***] send via the correspondent bank:

     Bank of America N.A.
     New York
     SWIFT code: BOFAUS3N.

3.6  Royalty Accounting. The tiered royalties under this Agreement shall be paid
     quarterly but calculated on an annual basis. Only a single royalty rate
     shall be applicable in any given year and that rate will be determined by
     the total Annual Net Sales. An adjustment to prior quarters in any given
     year shall be made in any subsequent quarter of the same year in which a
     threshold in a higher royalty bracket has exceeded. A yearend adjustment
     will be made, if a royalty threshold is exceeded in the fourth quarter.

3.7  Payments and Reports. Royalties payable pursuant to this agreement shall be
     due quarterly within forty five (45) days following the end of each
     calendar quarter for Annual Net Sales in such calendar quarter. All sales
     in foreign currencies shall be converted into United States dollars using
     the rate of exchange quoted by Bank of America and its successor(s) on the
     last business day of the calendar quarter in which the sales were made.
     Each such payment shall be accompanied by a statement of Annual Net Sales
     for the quarter (including number of units), applicable exchange rates and
     the calculation of royalty payable hereunder by Licensed Product and
     country. AMICUS THERAPEUTICS shall keep and shall cause its Affiliates and
     sublicensees to keep complete, true and accurate records for at least five
     (5) years for the purpose of showing the derivation of all milestone
     payments and royalties payable under this Agreement.

     3.7.1 NOVO NORDISK duly accredited representatives, which are reasonably
          acceptable to AMICUS THERAPEUTICS, shall have the rights to inspect
          and audit such records at any time with reasonable prior notice to
          AMICUS THERAPEUTICS or any of its Affiliates or sublicensees, but such
          right will not be exercised more often than once a year.

     3.7.2 Any adjustment required as a result of an audit conducted under this
          Article shall be made within thirty (30) days after the date on which
          NOVO NORDISK completed the audit. In the event of an underpayment by
          AMICUS THERAPEUTICS, its Affiliates and/or sublicensees, AMICUS
          THERAPEUTICS shall pay to NOVO NORDISK the amount underpaid plus
          interest (calculated on a daily basis) on the overdue payment from the
          date such payment was due to the date of actual payment an annual rate

          equal to the discount rate ("diskontoen") of the Danish National Bank
          plus 2% (two percent). In case of overpayment by AMICUS THERAPEUTICS,
          ifs Affiliates and/or sublicensees, AMICUS THERAPEUTICS may, at its
          option, offset any future royalty payments payable to NOVO NORDISK by
          the amount of the overpayment. Each Party shall have five (5) years
          after receipt by NOVO NORDISK of any royalty paid by AMICUS
          THERAPEUTICS, its Affiliates and/or sublicenses pursuant to this
          Agreement to dispute the amount of any such royalty payment.

3.8  Transfer of NOVO NORDISK Data. NOVO NORDISK will transfer, and will
     instruct its contractors about transfer, of NOVO NORDISK Data to AMICUS
     THERAPEUTICS after AMICUS THERAPEUTICS has given NOVO NORDISK a written
     notice that AMICUS wishes to receive such NOVO NORDISK Data. NOVO NORDISK's
     obligations on transfer of data will cease six (6) months after the
     Effective Date. After this date NOVO NORDISK will in good faith consider
     fulfilling requests from AMICUS THERAPEUTICS regarding additional
     information. NOVO NORDISK will charge AMICUS THERAPEUTICS the costs
     associated with such requests at a cost basis. The contact person at NOVO
     NORDISK will be head of Scientific Licensing, Pierre Honore
     (pfh@novonordisk.com).

3.9  AMICUS THERAPEUTICS shall deliver a written annual report on each
     anniversary of the Effective Date covering the preceding year regarding the
     status of the NOVO NORDISK Intellectual Property Rights and the Licensed
     Products identified, discovered or developed fully or partly through the
     use of Intellectual Property Rights by AMICUS THERAPEUTICS. Such annual
     report shall include, as a minimum; (a) identification by code number of
     Licensed Products identified, discovered or developed, using a method
     covered in whole or in part by the Intellectual Property Rights, or which
     reasonably could not have been identified, discovered or developed but for
     the Intellectual Property Rights or which are otherwise covered by the
     Intellectual Property Rights, unless AMICUS THERAPEUTICS provides
     contemporaneous written evidence to NOVO NORDISK that such identification,
     discovery or development took place before the date of issue or grant of
     relevant Intellectual Property Rights; (b) the status of any submissions to
     a regulatory agency in any country concerning Licensed Product; the
     identity of Third Parties that AMICUS THERAPEUTICS has granted sublicensees
     to under this agreement to; and, (c) such additional material as NOVO
     NORDISK may reasonably request. NOVO NORDISK shall maintain the
     confidentiality of all such reports and shall not use the information
     therein for any purpose other than determining compliance of AMICUS
     THERAPEUTICS with the terms of this Agreement.

3.10 The AMICUS THERAPEUTICS contact person responsible for communicating with
     the NOVO NORDISK under the reporting requirements of this Agreement shall
     be the same as is given in Article 16 (NOTICES), unless AMICUS THERAPEUTICS
     designates otherwise to NOVO NORDISK in writing.

3.11 All payments due under this Agreement shall be made without deduction other
     than such amount as AMICUS THERAPEUTICS is required to deduct or withhold
     by law. When making any payment due under this Agreement, AMICUS
     THERAPEUTICS shall also pay any value added (or similar) tax which is
     payable. The sums payable by AMICUS THERAPEUTICS are non-creditable and
     non-refundable. The previous sentences of this Article notwithstanding,
     each Party undertakes to cooperate with the other Party to achieve the tax
     arrangements that are most favourable for both Parties.

3.12 In the event of any delay in effecting the payments due under this
     Agreement by the due date, AMICUS THERAPEUTICS, its Affiliates and
     sublicensees agree to pay

     shall purchase and NOVO NORDISK shall sell and deliver to AMICUS
     THERAPEUTICS, [***] kg of the Compound, at a price of $[***] per gram. Such
     delivery shall be shipped no later than fifteen (15) calendar days after
     receipt of the purchase order. Payment terms and other terms for use of the
     Compound shall be established in such purchase order. NOVO NORDISK may
     require that a Materials Transfer Agreement is entered into in connection
     with such purchase.

     shall not apply to

     a)   Information, which at the time of disclosure is already in the public
          domain;

     b)   Information, which, after disclosure, becomes part of the public
          domain through no violation of this Agreement;

     c)   Information, which Disclosing Party is able to prove has been

          by Recipient's written records;

     f)   Information disclosed to the extent required by law or regulation
          provided that Recipient shall give the Disclosing Party prompt written
          notice and sufficient opportunity to object, time permitting, to such
          disclosure.

4.5  Notwithstanding the foregoing, Recipient may disclose Information of the
     Disclosing Party to reliable employees, consultants and agents if necessary

     order to fulfil its obligations under this Agreement, provided that such
     persons are bound by obligations of confidentiality and non-use to
     Recipient which are equal to the terms of this Agreement. Recipient shall
     ensure that such employees, consultants and agents be fully aware of the
     obligations of this Agreement and shall be responsible for any breach of

7    ENFORCEMENT OF INTELLECTUAL PROPERTY RIGHTS

7.1  Notification. Should NOVO NORDISK become aware that a Third Party has been
     or is threatening to infringe any of the Intellectual Property Rights, or
     that a Third Party is challenging the validity of any Intellectual Property
     Rights, NOVO NORDISK shall give AMICUS THERAPEUTICS prompt written notice
     detailing as many facts as possible concerning such infringement or
     potential infringement or challenge to validity.

     responsible for taking action as AMICUS THERAPEUTICS - in any event after
     consulting with NOVO NORDISK - may deem necessary to prevent an
     infringement of the Intellectual Property Rights; to enforce the
     Intellectual Property Rights and to defend the NOVO NORDISK Intellecutal
     Property Rights against any action challenging the validity of the NOVO
     NORDISK Patent Rights. No settlement shall be made unless with the prior
     written approval of NOVO NORDISK. Any sums recovered in a suit or
     settlement shall belong to AMICUS THERAPEUTICS. However, AMICUS
     THERAPEUTICES shall not name NOVO NORDISK as a coparty in the enforcement
     and defense of the Intellectual Property Rights without the express written
     consent of NOVO NORDISK and AMICUS THERAPEUTICS shall hold harmless NOVO
     NORDISK from all reasonable costs and expenses of such litigation,
     including reasonable attorney's fees. In the event NOVO NORDISK as the

     choice.

7.3  Obligations. AMICUS THERAPEUTICS shall be obligated to enforce any of the
     Intellectual Property Rights covered by this Agreement at its own expense.

8.1  If any claim challenging the validity or enforceability of any Intellectual
     Property Rights shall be brought against NOVO NORDISK, NOVO NORDISK shall
     promptly notify AMICUS THERAPEUTICS. Article 9.2 shall govern the
     disposition of any such claim.

8.2  If any Third Party challenges the validity or enforceability of any of the
     Intellectual Property Rights, AMICUS THERAPEUTICS agrees not to suspend any
     payments due to NOVO NORDISK until such time as that patent in Intellectual
     Property Rights is determined to be invalid or unenforceable by final
     judgement of a governmental agency or a court of competent jurisdiction
     from which no appeal can be or has been taken.

11.2 Either Party may terminate this Agreement on thirty (30) days written
     notice to the other Party ("the Notified Party") if any of the following
     events occur:

     (a)  If the Notified Party is in breach of any of the material terms or
          obligations of this Agreement and such breach remains uncured for
          sixty (60) days following receipt by the Notified Party of written
          notice of such breach (if such default is cured within the cure
          period, such written notice shall be null and void), provided that, if
          the Notified Party can establish to the reasonable satisfaction of the
          other Party that it is diligently and actively pursuing a cure at the
          expiration of the cure period, and that the default is reasonably
          capable of being cured, then the cure period shall be extended for up
          to ninety (90) days from the date of receipt of the written notice of
          breach by the Notified Party. For the avoidance of doubt, in the event
          of a dispute whether a Party is in breach of the material terms and
          obligations of the Agreement and/or whether the cure period shall be
          extended, the dispute shall be resolved under Article 10. The
          Agreement shall not terminate until a final decision has been reached
          either by the Parties or under Arbitration as set forth in Article 10.

     (b)  In the event the Notified Party shall have become bankrupt, or shall
          have made an assignment for the benefit of its creditors or there
          shall have been appointed a trustee or receiver of the Notified Party
          or for all or a substantial part of its property or any case or
          proceeding shall have been commenced or other action taken by or
          against the Notified Party in bankruptcy or seeking reorganization,
          liquidation, dissolution, winding-up, arrangement, composition or
          readjustment of its debts or any other relief under any bankruptcy,
          insolvency, reorganization, or other similar act or law of any
          jurisdiction now or hereafter in effect and any such event shall have
          continued for ninety (90) days undismissed, unbonded and/or
          undischarged. All rights and license granted under this Agreement by
          one Party to the other Party are, and shall otherwise be deemed to be,
          for purposes of Section 365(n) of the Bankruptcy Code, license of
          rights to "intellectual property" as defined under Section 101 (56) of
          the Bankruptcy Code. The Parties agree that the licensor under this
          Agreement shall retain and may fully exercise all of its rights and
          elections under the Bankruptcy Code in the event of a bankruptcy by
          the other Party. The Parties further agree that in the event of the
          commencement of a bankruptcy proceeding by or against one Party under
          the Bankruptcy Code of their respective countries, the other Party
          shall be entitled to complete access to any such intellectual property
          pertaining to the rights granted in the licenses hereunder of the
          Party by or against whom a bankruptcy proceeding has been commenced
          and all embodiments of such intellectual property. However, if NOVO
          NORDISK is the bankrupt party, this above shall only apply to the
          extent this is allowed under the Danish Bankruptcy Code
          ("Konkursloven").

11.3 Lack of payments due to NOVO NORDISK under this License Agreement or in
     relation to maintenance, defending and enforcing the Intellectual Property
     Rights shall always be considered material breach.

11.4 AMICUS THERAPEUTICS may terminate this License Agreement in its entirety at
     any time upon one hundred and eighty (180) days written notice to NOVO
     NORDISK.

     Party to oppose, the grant of any of the Intellectual Property Rights or
     disputes, or directly or indirectly assists any Third Party to dispute, the
     validity of any of the NOVO NORDISK Intellectual Property Rights.

11.6 The provisions under which this Agreement may be terminated shall be in
     addition to any and all other legal remedies which either Party may have
     for the enforcement of any and all terms hereof, and do not in any way

     Rights.

12   TERMINATION OF CERTAIN INTELLECTUAL PROPERTY RIGHTS

     of ninety (90) days that AMICUS THERAPEUTICS wishes to exclude certain NOVO
     NORDISK Intellectual Property Rights from the license granted under this
     Agreement. In this case those NOVO NORDISK Intellectual Property Rights
     excluded from the license granted under this Agreement shall revert to NOVO
     NORDISK. The Parties shall enter into an amendment to this Agreement
     stating that Intellectual Property Rights continue to be included in the
     Agreement. The license granted under this Agreement shall continue to be in
     full force and effect with respect to this remaining part of the
     Intellectual Property Rights.

     and 17 which shall survive expiration or any termination of the Agreement

13.3 The grant under Article 3 of this Agreement shall cease by termination of
     this Agreement and AMICUS THERAPEUTICS shall return its rights to NOVO
     NORDISK Intellectual Property Rights to NOVO NORDISK.

     rights to use in advertising, publicity or other promotional activities any
     name, trade name, trademark, or other designation of a party hereto,
     including any contraction, abbreviation, or simulation of any of the
     foregoing, unless the express written permission of the other party has

     party without prior written approval from such other party.

     obligations as set forth in the License Agreement. No such consent of the
     other party will be required for assignment of the License Agreement (a) in

     business of such party to which the agreement relates to a Third Party,
     whether by merger, sale of stock, sale of assets or otherwise, or (b) to
     any Affiliate. However, in the event of assignment to a successor by merger
     or by sale of all or substantially all of a party's assets, such successor
     shall not be entitled to exercise any rights or receive any benefits from
     this License Agreement until it has expressly assumed in writing to the
     other party the performance and obligations of all the assigning party's
     duties and obligations as set forth in the License Agreement. Any
     assignment of the License Agreement which is not in accordance with the
     aforementioned shall be void.

18.2 AMICUS THERAPEUTICS shall have the rights to assign or transfer any or all
     of its rights or obligations under this Agreement at any time after AMICUS
     THERAPEUTICS has paid the consideration set forth in Article 3.3.a, so long
     as the obligations in Article 18.1. are fulfilled.

18.6 No Waiver. The failure of any Party to enforce at any time any provision of

     such provision, right or election, or in any way affect the validity of
     this Agreement. The exercise by any Party of any right or election under
     the terms or covenants herein shall not preclude or prejudice any party
     from exercising the same or any other right it may have under this
     Agreement, irrespective of any previous action or proceeding taken by the
     Parties hereunder.

18.7 Severability. Should a court of competent jurisdiction later consider any

     into this Agreement.
