Re: Confidentiality Agreement ("Agreement")

Dear Don:

In connection with your engagement as a consultant (the "Relationship") with
Amicus Therapeutics, Inc. (the "Company"), the Company expects to make available
to you certain nonpublic information concerning its businesses, financial
condition, operations, assets and liabilities. As a condition to such
information being furnished to you and your partners, directors, officers,
employees, agents, advisors, and your affiliated or subsidiary companies
(including, without limitation, attorneys, accountants, consultants, bankers and
financial advisors) (collectively, "Representatives"), you agree to treat any
nonpublic information concerning the Company (whether prepared by the Company,
its Representatives or otherwise and irrespective of the form of communication)
which is furnished hereunder to you or to your Representatives by or on behalf
of the Company in accordance with the provisions of this Agreement, and to take
or abstain from taking certain other actions hereinafter set forth.

            1. CONFIDENTIAL INFORMATION.

                  (a) "Trade Secrets" shall mean information belonging to the
Company or its Representatives (collectively, the "Disclosing Party") or
licensed by it including, without limitation, formulae, patterns, compilations,
programs, devices, methods, techniques, or processes (including such information
that has commercial value to the Disclosing Party from a negative viewpoint,
such as the results of research which proves that certain processes used to
attempt to develop new technology will be unsuccessful), which is not commonly
known by or available to the public, was not your or your Representatives'
(collectively, the "Receiver") legitimate possession prior to the time of
entering this Agreement, and which information: (a) derives independent economic
value, actual or potential, from not being generally known to, and not being
readily ascertainable by proper means by, other persons who can obtain economic
value from their disclosure or use; and (b) is the subject of efforts that are
reasonable under the circumstances to maintain its secrecy.

                                  Page 5 of 8

<PAGE>

                  (b) "Proprietary Information" shall mean any information,
other than Trade Secrets, without regard to form, belonging to the Disclosing
Party or licensed by it including, without limitation, formulae, patterns,
compilations, programs, devices, methods, techniques, or processes, which is not
commonly known by or available to the public and which information is material
to the Disclosing Party, and all notes, analyses, compilations, studies,
interpretations or other documents prepared by the Receiver which contain,
reflect or are based upon, in whole or in part, the information furnished to the
Receiver by the Disclosing Party pursuant hereto; provided, however that
"Proprietary Information" shall not include any information which Receiver can
show (i) is or shall become generally known to the industry or the public
through no act or fault of Receiver, (ii) is received in good faith from any
third party who has the right to disclose such information and who has not
received such information, either directly or indirectly, from the Disclosing
Party, or (iii) any information which Receiver can show was in Receiver's
legitimate possession prior to the time of entering this Agreement.

                  (c) "Confidential Information" shall mean, collectively, both
Proprietary Information and Trade Secrets that are disclosed to the Receiver (a)
in documents or other tangible materials clearly marked as proprietary and
delivered to the recipient by the disclosing party, or (b) orally, or in any
other intangible form, provided, however, when first disclosed to the recipient,
the disclosing party tells the recipient the information is proprietary, and the
information is described and disclosed in documents or other tangible materials
clearly marked as proprietary and then delivered to the Receiver by the
Disclosing Party within thirty (30) calendar days after the information is first
disclosed to the Receiver.

            2. USE OF CONFIDENTIAL INFORMATION. You hereby agree that you and
your Representatives shall use the Confidential Information solely for the
purpose of evaluating a possible Relationship, and that the Confidential
Information will be kept confidential and you and your Representatives will not
disclose or use for purposes other than as permitted herein any of the
Confidential Information in any manner whatsoever; provided, however, that you
may make any disclosure of Confidential Information to your Representatives (i)
who need to know such information for the sole purpose of evaluating a possible
Relationship between the parties, (ii) who are provided with a copy of this
letter agreement and (iii) who agree to treat such information confidentially.
In addition to the foregoing, you agree as follows:

                  (a) Receiver will treat as confidential and will not, without
the prior written approval of the Disclosing Party, use (other than as set forth
herein), publish, disclose, copyright or authorize anyone else to use, publish,
disclose or copyright, either during the term of this Agreement or at any time
subsequent thereto, any information that constitutes Trade Secrets whether or
not the Trade Secrets are in written or tangible form.

                                  Page 6 of 8

<PAGE>

                  (b) Receiver will treat as confidential and will not, without
the prior written approval of the Disclosing Party, use (other than in the
performance of the purpose described in this Agreement), publish, disclose,
copyright or authorize anyone else to use, publish, disclose or copyright, any
Proprietary Information either during the term of this Agreement or for five (5)
years after the expiration or termination of this Agreement, with or without
cause, and whether or not the Proprietary Information is in written or other
tangible form.

            3. REQUIRED DISCLOSURE. In the event you or your Representatives are
requested or required (by oral questions, interrogatories, requests for
information or documents in a legal proceeding, subpoena, civil investigative
demand or other similar process) to disclose any of the Confidential
Information, you or your Representatives so requested or required shall provide
the Company with prompt notice of any such request or requirement so that the
Company may seek a protective order or other appropriate remedy and/or waive
compliance with the provisions of this letter agreement. If, in the absence of a
protective order or other remedy or the receipt of a waiver by the Company, you
or your Representatives are nonetheless, in the opinion of outside counsel,
legally compelled to disclose the Confidential Information, you or your
Representatives may, without liability hereunder, disclose to such tribunal only
that portion of the Confidential Information which such counsel advises is
legally required to be disclosed, provided, however, that you or your
Representatives exercise reasonable efforts to preserve the confidentiality of
the Confidential Information, including, without limitation by cooperating with
the Company to obtain an appropriate protective order or other reliable
assurance that confidential treatment will be accorded the Confidential
Information by such tribunal.

            4. RETURN OF CONFIDENTIAL INFORMATION. Upon termination of this
Agreement and at any time upon the request of the Company for any reason, you
will (i) promptly deliver to Company or destroy all written Confidential
Information furnished to you by or on behalf of the Company pursuant hereto (and
all copies-thereof and extracts therefrom) and (ii) promptly destroy all written
Confidential Information prepared by you which contain, reflect or are based
upon, in whole or in part, the information furnished to you by the Company
pursuant hereto (and all copies thereof and extracts therefrom) and such return
or destruction shall be certified in writing by your authorized officer;
provided, however, that in either case a copy may be retained by counsel of each
party solely for the purposes of maintaining an accurate record of the
Confidential Informations should a dispute under this letter agreement ever
arise. Notwithstanding the return or destruction of Confidential Information,
you and your Representatives will continue to be bound by their other
obligations as provided in this Agreement.

            5. NO REPRESENTATION OF ACCURACY. You understand and hereby
acknowledge that neither the Company nor any of its Representatives makes any
representation or warranty, express or implied, as to the accuracy or
completeness of the

                                  Page 7 of 8

<PAGE>

Confidential Information made available by it. You agree that neither the
Company nor any of its Representatives shall have any liability to you or your
Representatives relating to or resulting from the use of, or reliance upon, the
Confidential Information or any errors therein or omissions therefrom.

            6. MISCELLANEOUS. You agree to be responsible for any breach of this
agreement by any of your Representatives. No failure or delay by the Company or
any of its Representatives in exercising any right, power or privileges under
this agreement shall operate as a waiver thereof nor shall any single or partial
exercise thereof preclude any other or further exercise of any right, power or
privilege hereunder. In case any provision of this agreement shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions of this agreement shall not in any way be affected or
impaired thereby.

            7. GOVERNING LAW. This Agreement shall be governed by, and construed
in accordance with, the internal laws of the State of New Jersey without giving
effect to the principles of conflicts of laws thereof.

            8. COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

            9. TERM. Confidential Information may be disclosed hereunder until
the date that is one year from the date first written above unless otherwise
terminated or extended in writing by the parties. Notwithstanding the
termination of this Agreement, the obligations with respect to the use of
confidential information contained in Section 2 shall survive.

Please confirm your agreement with the foregoing by signing and returning one
copy of this letter to the undersigned, whereupon this letter agreement shall
become a binding agreement.

                                            Very truly yours,
