Dear Hamid:

     AMICAS, Inc., including its subsidiaries (the "Company") and you have
mutually decided to terminate your at-will employment effective as of April 30,
2005. Upon termination, you shall receive payment for all work performed by you
through your termination date along with payment for any accrued but unused
vacation time.

     In light of your service to the Company, if you sign and return this letter
agreement postmarked on or before April 4, 2005, and as long as you abide by the
other terms of this separation as described herein, the Company will provide you
with the severance benefits described in detail below. BY SIGNING AND RETURNING
THIS LETTER AGREEMENT (THE "AGREEMENT"), YOU WILL BE ENTERING INTO A BINDING
AGREEMENT WITH THE COMPANY REGARDING THE TERMS AND CONDITIONS SET FORTH IN THE
NUMBERED SECTIONS BELOW, INCLUDING THE SECTION REGARDING A RELEASE OF CLAIMS.
Therefore, you are advised to consult with an attorney before signing this
letter and you may take up to twenty-one (21) days to do so. If you sign this
letter, you may change your mind and revoke your agreement during the seven (7)
day period after you have signed it (the "Revocation Period") by notifying Carol
Camarda, Vice President, Human Resources in writing of your revocation. If you
do not so revoke, this letter will become a binding agreement between you and
the Company upon the expiration of the Revocation Period. If you choose not to
timely sign and return this letter, or if you revoke your acceptance in writing,
you shall not receive any severance benefits from the Company.

     Regardless of whether you sign this Agreement, you may be eligible to elect
to continue receiving group health insurance for any Company-sponsored health
plans participated in by you (including medical, dental, vision, and
prescription drugs, if applicable) as of your last date of employment with the
Company, pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985
("COBRA"). If you are eligible for and elect continuation of group health
insurance under COBRA, all premium costs shall be paid by you on a monthly basis
for as long as, and to the extent that, you remain eligible for COBRA coverage.
Please consult the COBRA materials to be provided by the Company under separate
cover for details regarding these COBRA benefits. All other Company-provided
benefits will cease upon your termination.

     The following numbered sections set forth the terms and conditions that
will apply if you timely sign and return this Agreement and do not revoke your
consent to this Agreement within the Revocation Period and you abide by the
other obligations described herein including but not limited to your obligation
to provide ongoing transition services to the Company not to exceed 16 hours per
week through June 30, 2005 under the direction and sole discretion of the
Company's CEO:
