A copy of this agreement is attached. In addition, as a condition of employment
Amicus requires a pre-employment drug screening.

      In consideration for all your services to be rendered to the Company your

(20) days paid vacation, three weeks during the year and one between Christmas
and New Years. Vacation accrues on a monthly basis. Because the Company expects
to regularly review its benefit programs to keep them up to date and
competitive, these programs are subject to periodic adjustments so that certain
features may be added, modified or deleted over time.

      If you are terminated without Cause, you will be eligible for a
continuation of six (6)month salary, an additional six (6) months of option

preceding year. "Cause" means for any of the following reasons: (i) willful or
deliberate misconduct by you that materially damages the company; (ii)
misappropriation of company assets; (iii) conviction of or a plea of guilty or
"no contest" to, a felony; or (iv) any willful disobedience of the lawful and
unambiguous instructions of the CEO of the company; provided that the CEO has
given you written notice of such disobedience or neglect and you have failed to
cure such disobedience or neglect within a period reasonable under the
circumstances.

      If there is a Change in Control Event and you resign for Good Reason or
are terminated without Cause within six months of such Change in Control Event,
then (i) you will be entitled to receive a continuation of twelve (12) months
salary, plus payment of a bonus payment equal to the bonus earned in the
preceding year and (ii) all unvested stock options will have their remaining
vesting schedule accelerated so that all stock options are fully vested.

      "Change in Control Event" means any of the following: (i) any person or
entity (except for a current stockholder) becomes the beneficial owner of
greater than 50% of the then outstanding voting power of the company; (ii) a
merger or consolidation with another entity where the voting securities of the
company outstanding immediately before the transaction constitute less than a
majority of the voting power of the voting securities of the company or the
surviving entity outstanding immediately after the transaction, or (iii) the
sales or disposition of all or substantially all of the company's assets. "Good
Reason" means (i) a change in your position with the company or its successor
that materially reduces your title, duties or level of responsibility; or (ii)
the relocation of the company or its successor greater than 50 miles away from
the then current location of the company's principal offices.

      Your right to receive accelerated vesting and severance payments pursuant
to the preceding three paragraphs shall be subject to the condition that you
execute a full release and waiver of all claims against the company and related
parties, in a form acceptable to the company.

      There is a two (2) year term on this agreement that will automatically
