                       COMPANY'S RIGHT TO PURCHASE WARRANT
                           AND CANCELLATION OF RIGHTS

         THIS  AGREEMENT,  (the  "Agreement")  dated as of the 5th day of April,
2001, by and between TechSys, Inc. (formerly Continental Choice Care, Inc.) (the
"Company") and Lazar & Company I.G., LLC (the "Holder").

         WHEREAS,  on August 21, 2000 the Company  issued to the Holder a Common
Stock  Purchase  Warrant to Purchase  up to  6,800,000  shares of the  Company's
Common Stock (the "Warrant"); and

         WHEREAS,  on  August  21,  2000 the  Holder  issued  to the  Company  a
Promissory Note in the principal amount of $1,050,000 (the "Note"); and

         WHEREAS,  on  December  5, 2000 the Holder  granted to the  Company the
right to purchase  certain  warrant  rights and  executed a  Company's  Right To
Purchase Warrant (the Warrant Rights Purchase Agreement"); and

         WHEREAS,  in accordance with the Warrant Rights Purchase  Agreement the
Company  exercised its rights  thereunder to reduce the Common Stock purchasable
under the Warrant and reduced the amount due under the Note; and

         WHEREAS,  the Holder and the Company  wish to amend the Warrant  Rights
Purchase  Agreement  by  accelerating  the  purchase  rights of the  Company and
altering the remaining rights of the Holder under the Warrant; and

         WHEREAS,  the terms used but not defined in this  Agreement  shall have
the meanings  ascribed to them as in the Warrant,  the Warrant  Rights  Purchase
Agreement, or the Note, as applicable.

         NOW THEREFORE,  in consideration of the mutual covenants and agreements
set forth below, the parties hereby agree as follows:

         1.       COMPANY'S RIGHT TO PURCHASE WARRANT.

         a. The  Company's  rights  pursuant to  Paragraphs 1 (c) and (d) of the
Warrant Rights Purchase Agreement to purchase from the Holder the Holder's right
to purchase  Shares under the Warrant,  are  accelerated and may be exercised by
the  Company  either on the dates  thereof  as set forth in the  Warrant  Rights
Purchase  Agreement  or, if  earlier,  at the  Effective  Time,  as  hereinafter
defined,  and,  if not  exercised  prior to the  Effective  Time shall be deemed
exercised  at the  Effective  Time  and the  Note  will  be  deemed  reduced  in
accordance  with the terms  thereof;  as a result of which,  together with prior
purchases under the Warrant Rights Purchase Agreement, all rights of the Company
to make such purchases  thereunder,  to the extent remaining  unexercised at the
Effective Time will have been fully exercised at the Effective time.

         b. The Holder  hereby  grants to the Company the right to purchase from
the Holder, at the Effective Time, the Holder's right to purchase 850,000 Shares
under  the  Warrant  for  $145,833.37  which  shall  be paid by a  reduction  of
$145,833.37  of the unpaid  principal  amount due from the Holder to the Company
pursuant to the Note, thus reducing the Note to an outstanding  principal amount
of  $700,000,  and the Company  hereby  exercises  such right  effective  at the
Effective Time.

         c. The  rights  to  purchase  shares  under  the  Warrant  having  been
purchased in their entirety by the Company on or before the Effective  Time, the
Warrant will be cancelled, will be no longer outstanding, and will be expired at
the  Effective  Time.  The holder will deliver the Warrant to the Company at the
Effective  time.  The Warrant is deemed hereby to have been  surrendered  to the
Company at the Effective Time.


         2.  AMENDMENT OF NOTE.  The Note shall remain in full force and effect,
except as it may be  specifically  amended or modified by this  Agreement and by
the purchases hereunder and under the Warrant Rights Purchase Agreement.

         3. AMENDMENT OF OTHER  DOCUMENTS.  The Warrant  having been  cancelled,
having expired,  being no longer outstanding,  and being deemed surrendered,  at
the Effective  Time,  all rights of the Holder  pursuant to any other  agreement
between  the  Company  and the  Holder  which  rights  expire  or are no  longer
effective when the Warrant is cancelled,  has expired, is no longer outstanding,
or has been  surrendered,  or when the  Holder  owns less that 25% of the Common
Stock of the Company, are terminated, expire, and are no longer effective, as of
the Effective Time.

         4. WARRANT GRANT.  At the Effective Time the Company shall grant to the
Holder a warrant  for the  purchase  of  100,000  common  shares  (the  "Warrant
Shares") of the Company,  exercisable  after the Effective Time until August 20,
2005, at a price of $1.50 per share.

         5. EFFECTIVE TIME.  The Effective Time under this Agreement is the time
of the  occurrence  of both (i) the  Effective  Time of the  currently  proposed
merger (the  "Merger") of Newco TKSS,  Inc., a wholly  owned  subsidiary  of the
Company,  with and into Fuel  Cell  Companies,  Inc.  ("FCCI")  pursuant  to the
agreement  executed by FCCI, the Company,  and a subsidiary of the Company dated
as of April 5,  2001  including  the  Merger or other  acquisition  transaction,
arising from the  amendment or revision of such  agreement and (ii) the delivery
to the Holder of the shares of TechSys,  Inc, or other survivor in the Merger or
other  acquisition  transaction,  arising from the amendment or revision of such
agreement,  in accordance with the letter agreement  between the Holder and FCCI
dated  the  date  hereof  (the  "Letter  Agreement  Shares")  accompanied  by an
undertaking by the Company,  in accordance with paragraph 6 hereof,  to grant to
the Holder "piggyback" registration rights.

         6. Undertaking to provide Piggyback  Registrations.  In the undertaking
relating to  "piggyback"  registration  rights  referred to in  paragraph 5, the
Company shall provide for rights substantially as follows:

         (a) Right to Include.  Each time the Company proposes for any reason to
register any of its common stock under the  Securities  Act for the account of a
stockholder  or  stockholders   of  the  Company,   other  than  pursuant  to  a
Registration  Statement on Forms S-4 or S-8 (or similar or  successor  forms) (a
"Proposed Registration"), the Company shall promptly give written notice of such
Proposed  Registration  to the Holder (which notice shall be given not less than
30 days  prior to the  expected  effective  date of the  Company's  Registration
Statement)  and shall offer the Holder the right to request  inclusion of any or
all of the  Holder's  Letter  Agreement  Shares;  provided,  that,  the  maximum
percentage  of the Holder's  Letter  Agreement  Shares that the Company shall be
required to register on any such registration  statement shall equal the maximum
percentage of shares of common stock of any stockholder being registered for the
account of such stockholder pursuant to such Registration Statement.  The rights
to piggyback  registration may be exercised an unlimited number of occasions but
such rights shall expire on December 31, 2007.

         (b) Procedure.  The Holder shall have 10 days after the date of receipt
of the Company's  notice to deliver to the Company a written request  specifying
the  number  of Letter  Agreement  Shares  the  Holder  intends  to sell and the
Holder's  intended  method of  disposition.  The Holder  shall have the right to
withdraw the Holder's  request for  inclusion of the Holder's  Letter  Agreement
Shares, in any Registration Statement by giving written notice to the Company of
such  withdrawal;  provided,  however,  that the  Company may ignore a notice of
withdrawal made within the 24 hours before the time the  Registration  Statement
is to become effective. The Company may at any time withdraw or cease proceeding
with any such  Proposed  Registration  if it shall at the same time  withdraw or
cease  proceeding  with the  registration  of all other  shares of common  stock
originally   proposed  to  be  registered.   In  the  event  that  the  Proposed
Registration  by the Company  is, in whole or in part,  an  underwritten  public
offering of securities of the Company, any request under this Section 6(b) shall
specify that the Letter  Agreement Shares be included in the underwriting on the
same terms and conditions as the shares,  if any,  otherwise  being sold through
underwriters  under such  registration.  The  Company  may at any time limit the
number of the Holder's  Letter  Agreement  Shares to be included in any Proposed
Registration (either underwritten or not) upon a good faith determination by the
board of  directors of the Company or upon the advice of such  underwriter  that
the  inclusion  of the  entire  amount  of such  Letter  Agreement  Shares  will
materially  interfere with the success of the offer of other shares  included in
the registration;  provided, that, any such limitation made by the Company shall
be made pro rata on the basis of shares to be registered  for the account of the
Holder and all other stockholders to be included in the Proposed Registration.

         IN WITNESS WHEREOF,  the parties have executed this Agreement as of the
date first set forth above.
