	       2.  The Company shall retain Beck as a consultant, the terms of
such consultancy to be as follows:
		   a.   The period of the consultancy arrangement shall
commence on January 1, 1995 and end on December 31, 1999 (the "Consulting
Period") unless sooner terminated (i) by the Company for "Cause" (as defined
below) or (ii) by Beck for "Cause".  During the Consulting Period, Beck will
render such advice and services as the Company may reasonably require, and
will assist and cooperate with the Company in connection with any litigation
or Claims in which any of the Companies is involved in which Beck's testimony
or assistance is deemed necessary by the Company's internal or external legal
counsel; provided, however, that the parties agree that Beck shall not be
required to devote more than 90 days in any twelve-month period to the
performance of his obligations under this Agreement.  The termination of this
consultancy arrangement, whether by either or both Beck and the Company or by
the expiration of the Consulting Period, in no way terminates or modifies the
parties' obligations, duties, and rights set forth in Paragraphs 11, 14, 18
and 19 of this Agreement or in the Termination Agreement.  The Consulting
Period shall not be extended or renewed, except as mutually agreed to and set
forth in writing by Beck and the Company.
		   b.   For purposes of Paragraph 2 of this Agreement, "Cause"
for termination by the Company of the consulting portion of this Agreement
shall be limited to the following conduct, actions, or inactions of Beck:

			(i)  Beck's engaging in willful or intentional
	       conduct, actions, or inactions in violation of his obligations
	       under this Agreement or under the Termination Agreement or
	       knowing violation or reckless disregard of law, governmental
	       regulation, or judicial decree which has caused substantial
	       injury to any of the Companies, financial or otherwise;

		       (ii)  Beck's conviction of a felony, as evidenced by a
	       binding and final judgment, order, or decree of a court of
	       competent jurisdiction, in effect after exhaustion or lapse of
	       all rights of appeal; or

		      (iii)  the willful or continual failure by Beck to
	       perform his duties and responsibilities under this Agreement.

		   c.   For purposes of Paragraph 2 of this Agreement, "Cause"
for termination by Beck of the consulting portion of this Agreement shall be
limited to the Company's engaging in intentional conduct in violation of its
obligations under this Agreement.
		   d.  Any termination of this Agreement for Cause shall not
take effect until the party attempting to so terminate the Agreement shall
have notified the other party in writing of the specific event(s) or
circumstance(s) constituting Cause, and the recipient of such notice shall
have had a period of not less than 30 days following the receipt of such
notice to cure such event or circumstance.
	       3.  a.   During the Consulting Period, Beck shall be available
to perform such services, including assistance with Claims and litigation as
described above, as shall be reasonably requested by the Company.  In
consideration of Beck's agreement to be available to perform such services,
the Company shall pay Beck $8,333 per month during the Consulting Period.
Such payments shall be made monthly, in arrears.
		   b.   If, pursuant to Paragraph 2(a) of this Agreement, this
consultancy arrangement is terminated for Cause by the Company, Beck shall not
be entitled to any further payment hereunder, except that Beck shall be paid
for services rendered through the date of termination.  If this consulting
arrangement is terminated for Cause by Beck, or is terminated as a result of
Beck's death or Beck's inability to perform his obligations hereunder as a
result of his physical or mental disability, the Company will remain obligated
to make all payments owing hereunder to Beck or his estate, as the case may
be, in accordance with the provisions of this Agreement.
		   c.   Beck will be given reasonable advance notice in
writing of the Company's needs for his professional services.
	       4.  Beck agrees to execute any forms or documents that the
Company normally requires independent contractors to complete in order to
comply with accounting and tax requirements.
	       5.  During the Consulting Period, Beck shall reside in the
location of his choice but shall make himself reasonably available to provide
consulting services hereunder at such locations as may be reasonably requested
by the Company, including at the offices of the Company's clients, outside
legal counsel, and/or experts.  The time Beck spends in traveling to the
offices of the Company, its clients, its outside legal counsel, or its experts
or to a legal proceeding on behalf of the Company shall not be treated as time
spent providing consultant services.  Beck shall be responsible for all
travel, transit, lodging, meal and other expenses incurred in the performance
of his duties hereunder; provided, however, that Beck shall be reimbursed for
such expenses in connection with any travel requested by the Company to a
destination more than fifty miles from his place of residence.
	       6.  During the Consulting Period, Beck shall perform such
services as shall be requested by Francis X. Ferrara (the Company's
"Designee").  The Company shall notify Beck in writing of any successor
Designee.  Under no circumstances shall Beck render any consultant services to
the Company without the express prior request of the Designee.  Beck shall
have exclusive control over the details and the means by which, and the manner
in which, he accomplishes the duties he has been retained to perform.
	       7.  Beck shall make every reasonable effort to make himself
available to perform his consultant services during normal business hours (8
a.m. to 5 p.m.) of the normal business week (Monday to Friday) or at such other
hours or days as the parties may mutually agree to in writing.  Beck shall
make every reasonable effort to accommodate the legitimate and significant
schedule requirements of the Company, its outside legal counsel, or its
experts, and the Company shall make every reasonable effort to accommodate the
legitimate and significant schedule requirements of Beck.
	       8.  During the Consulting Period, Beck will be an independent
contractor and not an employee or agent of any of the Companies for any
purpose whatsoever.  Beck acknowledges that he will not participate in any
benefits or privileges available to employees of any of the Companies during
the Consulting Period.
	       9.  Beck is not authorized to enter into any contractual
obligations of any nature whatsoever on behalf of any of the Companies.
Nothing in this Agreement is intended to nor shall be interpreted to confer
any authority upon Beck to enter into any contractual obligations of any
nature whatsoever on behalf of any of the Companies.  Beck shall not at any
time during the Consulting Period represent that, or act as if, he were so
authorized.
	     10.   Because Beck will be an independent contractor, the Company
will not withhold federal, state, and local taxes and Social Security from any
amounts due Beck under this Agreement.  In the event an administrative agency
or a court of competent jurisdiction determines that all or part of any amount
paid to Beck under this Agreement is subject to withholding or tax, (i) such
determination will not affect the enforceability of this Agreement and will
not entitle Beck to receive any additional payments from any of the Companies,
(ii) Beck will be solely responsible for paying any such taxes or amounts
determined not to have been properly withheld, including any interest and
penalties that may be assessed, and (iii) Beck will indemnify and hold the
Company harmless from and against any Claims for any such taxes or amounts
determined not to have been properly withheld, including any interest and
penalties that may be assessed.
	     11.   Beck acknowledges and represents that upon termination of
the Consulting Period he will immediately return to the Company all originals
and copies of all documents, memoranda, notes, records, reports, and other
property of the Companies that he possessed or had under his control during
the Consulting Period and that he will not disclose to any other person or
Entity, or use for his own benefit or gain, and agrees to return to the
Company if in his possession or under his control, any Confidential
Information of the Companies obtained by him incident to this consultancy
arrangement.  The obligations of Beck under this Paragraph 11 shall be in
furtherance of, and not in limitation of, any other similar covenants Beck may
have entered into in the Termination Agreement.
	     12.   Beck shall not transfer or assign any of his rights or
obligations under this Agreement without the express prior written consent of
the Company.
	     13.   The parties hereto represent and acknowledge that, in
executing this Agreement, they do not rely and have not relied upon any
representation or statement, written or oral, made by any of the parties or by
any of the parties' agents, attorneys, or representatives with regard to the
subject matter, basis, or effect of this Agreement or otherwise, other than
those specifically stated in this written Agreement and in the Termination
Agreement.
	     14.   This Agreement shall be binding upon and shall inure to the
benefit of the parties hereto, the Other Defendants and their respective
heirs, administrators, representatives, executors, Companies, successors, and
assigns.
	     15.   Any waiver by either party of a breach of any provision of
this Agreement shall not operate as or be construed as a waiver of any
subsequent breach hereof, or as a waiver of a breach of any other provision.
	     16.   Should any part, term, or provision of this Agreement be
declared or be determined by any court of competent jurisdiction to be
illegal, invalid, or unenforceable, the legality, validity, and enforceability
of the remaining parts, terms, or provisions shall not be effected thereby,
and said illegal, unenforceable, or invalid part, term, or provision shall be
deemed not to be a part of this Agreement.
	     17.   This Agreement shall be interpreted in accordance with the
plain meaning of its terms and not strictly for or against any of the parties
hereto.
	     18.   This Agreement and all provisions hereof shall be governed
by and construed under the laws of the State of New Jersey.
	     19.   a.   Except as provided in subparagraph (d) immediately
below, any and all Claims against the Companies or the Other Defendants
arising out of or relating to (i) this Agreement or (ii) any breach of any
provision of this Agreement shall be settled by arbitration.  Such arbitration
proceeding shall be conducted pursuant to the Commercial Arbitration Rules of
the American Arbitration Association ("AAA") then in effect, by a single
arbitrator, and shall be held in Branchburg, New Jersey or such other location
as the parties mutually agree to in writing.  The arbitrator shall not have
the power to award punitive damages.  Each party shall pay his or its own
costs of the arbitration proceeding.  The judgment upon the award rendered by
the arbitrator may be entered in any court having competent jurisdiction
thereof.  Before resorting to arbitration, the parties agree first to try in
good faith to settle the dispute by mediation administered by the AAA under its
Commercial Mediation Rules.  With respect to Claims that are within the scope
of this Paragraph 19, if Beck has the same, similar or related Claims against
any of the Other Defendants, and if Beck seeks to litigate such Claims against
the Other Defendants in a civil action or any other proceeding (including
before an administrative agency), Beck agrees that any or all of such Other
Defendants may compel Beck to arbitrate his Claims against them pursuant to the
terms of this Paragraph 19.
		   b.   The arbitrator selected by the parties pursuant to the
AAA rules shall have expertise in commercial arbitration and shall hear and
determine the case promptly.  The burden of persuasion shall at all times be
upon the party seeking relief.
		   c.   In the event Beck files suit in a court of competent
jurisdiction and asserts that certain Claims are not subject to arbitration
under this Paragraph 19 because of the limitation on the power of the
arbitrator to award punitive damages (the "Limitation"), the parties agree that
they will request the court to resolve that legal issue on an expedited basis,
and if the court rules in favor of Beck on the Limitation issue, the parties
agree as follows:  (i) the arbitration shall proceed as if this Paragraph 19
did not contain such Limitation; (ii) the parties will request the court to
enter judgment in favor of Beck on the Limitation issue, at which time the
Company may appeal that ruling; (iii) in the event the arbitrator determines
that Beck is entitled to punitive damages, the punitive damages aspect of the
arbitrator's award will be stayed pending the exhaustion or lapse of all
rights of appeal of the Company under (ii) immediately above; and (iv) in the
event an appellate court rules in favor of the Company on the Limitation
issue, the arbitrator shall vacate the award of punitive damages.
	       The procedures set forth in this subparagraph (c) shall also
apply in the event Beck seeks relief in some other tribunal, such as an
administrative agency, and the Company files a civil action to compel
arbitration.
		   d.   Nothing in subparagraph (a) immediately above shall be
construed or interpreted to preclude the Company from filing suit in a court
of competent jurisdiction in order to enforce its rights and remedies under
Paragraph 11 of this Agreement.  In any such suit, the court is empowered to
and shall resolve any dispute as to whether the Claim asserted by the Company
is within the scope of Paragraph 11 of this Agreement, and the court shall not
refer such dispute to arbitration under subparagraph (a) immediately above.
	     20.   All representations and warranties herein shall survive any
termination or expiration of this Agreement, and the termination or expiration
of this Agreement shall not affect the enforceability of Paragraphs 10, 11,
12, 14, 18, 19, 20 and 21 of this Agreement, which Paragraphs shall survive
the termination or expiration of this Agreement.
	     21.   All notices required to be transmitted herein shall be sent
in writing and by first class mail or hand delivery as follows:
