paragraph 23 hereinbelow, through October 1, 2002, Amendola shall dispose of no
Currently-Owned Shares for less than the greater of (x) ten dollars and no cents

<PAGE>
executing this Agreement, and that this Agreement shall not become effective

      15. This Agreement shall not in any way be construed as an admission by

of the Released Parties arising from or in any manner connected with, Amendola's
employment relationship with the Company, the cessation of Amendola's employment

Company pursuant to this Agreement, or to waive and forfeit his right to
Additional Stock Options and to Supplemental Stock Options or to reimburse the
Company and the Released Parties for their attorneys' fees and costs incurred in
connection with any such lawsuit or other legal claim or challenge). For
purposes of this paragraph 16, the determination of whether Amendola has
breached this paragraph 16 shall be within the sole discretion of the Company.

      17. Amendola, for, together with and on behalf of himself and his heirs,
beneficiaries, executors, administrators, agents, representatives, attorneys,
successors and assigns, expressly


                                       19
<PAGE>
represents and warrants to the Company that it is understood and agreed that, as

Company are to remain strictly confidential. Amendola, for, together with and on
behalf of himself and his heirs, beneficiaries, executors, administrators,
agents, representatives, attorneys and successors, and his counsel, agrees and
promises to keep the terms and conditions of this Agreement and of Amendola's
separation from the Company, and the exchange of consideration hereunder,
strictly confidential to the extent permitted by law, and that he will not
disclose or consent to disclosure by others, discuss, or otherwise disseminate
that information to anyone in any way, unless specifically required by law to do

from the Company, Amendola is prohibited from responding orally, and is
permitted to respond in writing only in the form annexed hereto as Exhibit B,
and shall not reveal the terms or substance of any part of this Agreement or of
his separation from the Company. Amendola agrees that any breach by him or any
person or entity on his behalf of this paragraph 17 shall constitute a material
breach of this Agreement, as a result of which, and in addition to any other
legal and equitable remedies available to the Company, Amendola shall waive and
forfeit, and hereby waives and forfeits, his right to any Additional Stock
Options and any Supplemental Stock Options as set forth in paragraph 6
hereinabove, which right shall be irrevocably forfeited, and shall be obligated
to pay the attorneys' fees and


                                       20
<PAGE>
costs incurred by the Company in connection with any lawsuit or other proceeding
related to enforcement or litigation of this paragraph 17. For purposes of this
paragraph 17, the determination of whether Amendola has breached thus paragraph
17 shall be within the sole discretion of the Company.

      18. (a) Amendola, to the best of his knowledge and belief, for, together
with and on behalf of himself and his heirs, beneficiaries, executors,
administrators, agents, representatives, attorneys, successors and assigns,
expressly represents and warrants to the Company that, during the Inventions
Employment Period, Amendola did not commit any act(s) or omission(s), or make
any oral or written statement(s), representation(s) or disclosure(s), accurate
or inaccurate, that, directly or indirectly, during the Employment Inventions
Period, may have resulted in, caused or otherwise contributed to, or, following
the termination of the Inventions Employment Period, may result in, cause or
otherwise contribute to, any reduction, impingement or other compromise of the
Company's interest(s) in any of its intellectual property, including, without
limitation, patentable inventions, the patents and other intellectual property
that the Company acquired from Amendola and GP Strategies Corporation pursuant
to that certain Amended and Restated Agreement dated August 1, 2000 by and among
Amendola, GP Strategies Corporation and the Company and Appendix A thereto
(consisting of an Assignment by Amendola to the Company executed by Amendola on
May 24, 2000), and the patents and other intellectual property that the Company
acquired from Amendola and GP Strategies Corporation pursuant to that certain
Assignment and Assumption of License Agreement dated as of December 17, 1998
between GP Strategies Corporation and the Company to which Amendola consented.
In the event that it is determined by the Company that any such


                                       21
<PAGE>
act(s) or omission(s) that Amendola committed, or oral or written statement(s),
representation(s) or disclosure(s) that Amendola made, has directly or
indirectly resulted in, caused or otherwise contributed to, or directly or
indirectly results in, causes or otherwise contributes to, any reduction,
impingement upon or other compromise of the Company's interest(s) in any such
intellectual property of the Company, such event shall constitute a material
breach of this Agreement, as a result of which Amendola shall forfeit, and
hereby forfeits, his right to any Additional Stock Options and any Supplemental
Stock Options as set forth in paragraph 6 hereinabove, which right shall be
irrevocably forfeited. For purposes of this paragraph 18(a), the determination
of whether any act(s) or omission(s) that Amendola committed, or oral or written
statement(s), representation(s) or disclosure(s) that Amendola made, has
directly or indirectly resulted in, caused or otherwise contributed to, or
directly or indirectly results in, causes or otherwise contributes to, any
reduction, impingement upon or other compromise of the Company's interest(s) in
any such intellectual property of the Company, shall be within the sole
discretion of the Company.

      (b) Amendola agrees to provide any and all assistance and cooperation
requested by the Company in connection with any and all issues and/or disputes
concerning, relating to or arising from the Company's rights to or interests in
any of its intellectual property, including, without limitation, issues or
disputes concerning, relating to or arising from claims of persons or entities
other than the Company to any right to or interest in any such intellectual
property. With respect to any such request for assistance or cooperation,
provided that the Independent Consulting Agreement is in force and has not been
terminated, Amendola shall not be entitled to any compensation for such
assistance or cooperation by virtue of this Agreement, provided


                                       22
<PAGE>
however, that the Company shall compensate the Independent Consultant in
accordance with the terms and conditions of the Independent Consulting
Agreement. With respect to any such request by the Company for acceptance or
cooperation made by the Company subsequent to the termination of the Independent
Consulting Agreement, the Company shall compensate Amendola at the rate of
$125.00 per hour, such hourly rate to be increased annually on the anniversary
date of the termination of the Independent Consulting Agreement at the rate of
five percent per annum. In the event that Amendola fails to provide any
assistance or cooperation requested by the Company in connection with any such
issues or disputes, such failure shall constitute a material breach of this
Agreement, as a result of which Amendola shall forfeit, and hereby forfeits, his
right to any Additional Stock Options and any Supplemental Stock Options as set
forth in paragraph 6 hereinabove, which right shall be irrevocably forfeited.
For purposes of this paragraph 18(b), the determination of whether Amendola has
breached this paragraph 18(b) shall be within the sole discretion of the
Company.

      19. Amendola understands and acknowledges that, pursuant to this
Agreement, other than the rights expressly set forth in this Agreement, he has
expressly waived all his rights against the Released Parties.

      20. Amendola represents and warrants to the Company that he has the full
power, capacity, and authority to enter into this Agreement, and that no portion
of any claim, right, demand, action, or cause of action that Amendola has or
might have had arising out of the acts, events, transactions, and occurrences
referred to herein have been assigned, transferred, or conveyed to any person
not a party to this Agreement, by way of subrogation, operation of law, or
otherwise, and that no releases or settlement agreements are necessary or need
to be obtained from any other


                                       23
<PAGE>
person or entity to release and discharge completely any of Amendola's claims
released in this Agreement.

      21. Amendola represents and warrants to the Company that Amendola
understands that if the facts upon which this Agreement are found hereafter to
be different from the facts now believed to be true, this Agreement will remain
binding and effective and the parties expressly accept and assume the risk of
such possible differences and agree that this Agreement shall remain binding and
effective, notwithstanding such potential differences.

      22. Amendola acknowledges that he has entered into this Agreement freely,
knowingly, and voluntarily; it is further understood and agreed that this
Agreement was reached and agreed to by the parties in order to avoid the expense
and uncertainties of potential litigation.

      23. This Agreement shall become effective on the eighth day after Amendola
and the Company execute this Agreement, provided however, that Amendola has not
revoked this Agreement in writing within seven days after executing this
Agreement in accordance with paragraph 14(f) hereinabove or in any other manner
("the Effective Date"). Amendola's non-revocation of this Agreement in writing
within seven days after executing this Agreement in accordance with paragraph
14(f) hereinabove or in any other manner is a condition precedent to this
Agreement becoming effective, to each and every obligation of the Company set
forth in this Agreement, including, without limitation, the Company's
obligations set forth in paragraphs 4 through 9 hereinabove, and to the
effectiveness of the Independent Consulting Agreement.

      24. Amendola covenants not to seek or apply for future employment with the
Company or any of its parents, subsidiaries, affiliates or successors. Amendola
also acknowledges that his employment relationship with the Company and its
parents, subsidiaries, affiliates and successors has been permanently and
irrevocably severed and that neither the Company nor any of its parents,
subsidiaries,


                                       24
<PAGE>
affiliates or successors has any obligation, contractual or otherwise, to
rehire, recall or hire him in the future. Amendola agrees that any attempt by
him to become employed by the Company or any of its parents, subsidiaries,
affiliates or successors will constitute a material breach of this Agreement.

      25. (a) This Agreement shall inure to the benefit of and be binding upon
Amendola and any of his heirs, administrators, executives and assigns or any
other individual or entity who may claim by or through him. Amendola's rights
and obligations under this Agreement shall not be assigned, pledged, or
encumbered by him without the Company's written consent.

      (b) No modification, amendment or waiver of any provision of this
Agreement shall be effective unless approved in writing by both parties. The
failure of either party at any time to enforce any of the provisions of this
Agreement shall not be construed as a waiver of such provisions and shall not
affect the right of such party thereafter to enforce each and every provision
hereof in accordance with its terms.

      (c) Whenever possible, each provision of this Agreement shall be
interpreted in such manner as to be effective and valid under applicable law,
but if any provision of this Agreement shall be held to be prohibited by or
invalid under applicable law, such provision shall be ineffective only to the
extent of such prohibition or invalidity, without invalidating the remainder of
such provision or the remaining provisions of this Agreement.

      (d) This Agreement is complete and sets forth the entire understanding of
the parties regarding the subject matter thereof. All existing agreements,
contracts, or understandings between the parties, whether oral or written,
relating to the subject matter of this Agreement are hereby superseded and
rendered invalid by this Agreement, with the sole exception of the


                                       25
<PAGE>
following: (i) that certain Stock Option Agreement (Incentive and Non-Qualified
Stock Options) dated October 3, 2000, (ii) that certain Stock Option Grant
Notice dated July 13, 2000, (iii) the Independent Consulting Agreement, (iv)
that certain Amended and Restated Agreement dated August 1, 2000 by among
Amendola, GP Strategies Corporation and the Company and Appendix A thereto
(consisting of an Assignment by Amendola to the Company executed by Amendola on
May 24, 2000), and (v) that certain Assignment and Assumption of License
Agreement dated as of December 17, 1998 between GP Strategies Corporation and
the Company to which Amendola consented. The parties acknowledge that, as of
October 1, 2001, the Company possesses no right of first refusal with respect to
Inventions that Amendola created, conceived of, made, prepared, worked on or
contributed to the creation of during the Inventions Employment Period.

      (e) All questions concerning the construction, validity, interpretation
and enforcement of this Agreement shall be governed by the internal laws of the
State of New York without regard to its conflicts of laws principles.

      (f) Any and all disputes relating to this Agreement shall be brought
exclusively in the federal or state courts located in the City, County, and
State of New York, and the parties hereby expressly represent and agree that
they are subject to the personal jurisdiction of said courts, and each of the
parties hereby irrevocably consents to the jurisdiction of such courts in any
legal or equitable proceedings related to such dispute and waives, to the
fullest extent permitted by law, any objection which it may now or hereafter
have that the laying of the venue of any legal proceedings related to such
dispute which is brought in any such court is improper or that such proceedings
have been brought in an inconvenient forum.

      (g) Amendola acknowledges that any breach of paragraphs 11 or 12 would
constitute a material breach of this Agreement and may cause great or
irreparable injury to the Company for which pecuniary compensation would not
afford adequate relief, or it would be extremely


                                       26
<PAGE>
difficult to ascertain the amount of the compensation which would afford
adequate relief. Therefore, in the event of an actual or threatened breach of
paragraphs 11 or 12 of this Agreement, Amendola agrees that the Company has the
right to seek and obtain equitable relief, including injunctive relief and
specific performance as against Amendola, in addition to any other rights and
remedies it may have, for Amendola's threatened or actual breach of paragraphs
11 and 12 hereinabove.

      (h) The "WHEREAS" recitals are an integral part of this Agreement, and are
therefore incorporated herein as a part of this Agreement.

      (i) This Agreement may be executed in counterparts, each of which together
constitute one and the same instrument.

      26. Amendola expressly acknowledges and agrees that he has had the
opportunity to consult with an attorney of his own choice and has entered into
this Agreement freely, knowingly and voluntarily. It is further understood and
agreed that this Agreement was reached and agreed to by the parties in order to
avoid the expense of litigation, as well as the uncertainties of potential
litigation. Amendola agrees and acknowledges that he has read this Agreement
carefully and fully understands all of its provisions, including the legal
effect of all of its provisions. By signing below, Amendola acknowledges that he
has voluntarily accepted the terms and conditions of this Agreement.

Mr. Steven C. Amendola

Dear Mr. Amendola:

      This letter is in reference to that certain Separation Agreement and
Release in Full effective as of December 11, 2001 (the "Agreement"), between
Millennium Cell Inc., a Delaware corporation (the "Company") and you, a resident
of the State of New Jersey. Capitalized terms used herein, unless otherwise
defined or unless the context otherwise indicates, shall have the same meanings
as set forth in the Agreement. The Agreement is hereby amended as follows:

1.    Section 7(a).

      Section 7(a) is hereby amended to read in its entirety as follows:

      "7. (a) The parties hereby acknowledge that Amendola beneficially owns

the Company as of the Effective Date, as term is defined in paragraph 23
hereinbelow (the "Currently-Owned Shares")."

2.    Section 8.

      Section 8 is hereby amended to ready in its entirety as follows:

      "8. In the event that Amendola's "Continuous Service", as that term is

<PAGE>

requests not to stand for election or reelection to the Company's Board of
Directors, then notwithstanding anything in this Agreement to the contrary,
Amendola shall have a period of up to one year following his termination of
"Continuous Service" to exercise his Additional Stock Options and his

shall not apply in the event that: (w) the Independent Consultant terminates the

the Independent Consulting Agreement, (x) the Company terminates the Independent
Consulting Agreement for Cause pursuant to paragraph 12(b) of the Independent
Consulting Agreement, (y) Amendola ceases to own at least seventy-five percent
of the outstanding capital of Independent Consultant, or (z) Amendola ceases to

      Except for the aforementioned amendments to Section 7(a) and Section 8 of
the Agreement set forth in this letter, no other terms or provisions of the
Agreement are being or have been amended, and all other terms and provisions of
the Agreement shall remain in full force and effect.

                                Very truly yours,
