Item 2.    Acquisition or Disposition of Assets

     On June 18, 1999, National Discount Brokers Group, Inc. (the "Registrant")
and its wholly owned subsidiary, SHD Corporation ("SHD"), disposed of their
membership interests in Equitrade Partners, L.L.C., a New York Stock Exchange
specialist ("Equitrade"), pursuant to the Amended and Restated Purchase
Agreement dated as of June 11, 1999 among Spear, Leeds & Kellogg Specialists
LLC, the Selling Members listed on the Signature Pages thereto and the Members'
Representative (the "Purchase Agreement").  The Registrant and SHD owned a
combined 46.845% membership interest in Equitrade.  Prior to the closing, the
Registrant exercised its right to purchase .03% membership interests in
Equitrade from three special members in exchange for cash equal to the capital
accounts of these special members. The balance of the membership interests in
Equitrade were also purchased by Spear, Leeds & Kellogg Specialists LLC ("SLK")
pursuant to the Purchase Agreement.

     The description of the Purchase Agreement contained herein is a summary and
is not complete.  The Purchase Agreement which is filed as an exhibit with this
filing is incorporated herein by reference.  The Registrant and SHD (the "NDB
Group") received approximately $85 million in cash from SLK, of which
approximately $3.6 million is being held in escrow pending post closing
adjustments.  The cash received is net of the repayment of a $15 million loan
plus accrued interest from the parent of SLK to the Registrant.  The cash
payment represented principally the gain on the sale, the return of NDB Group
capital invested in Equitrade, and the repayment to the Registrant of
subordinated indebtedness of Equitrade.  The cash payments made to the NDB Group
are subject to post closing adjustments described in the Purchase Agreement.

     SLK is owned by Spear, Leeds & Kellogg, L.P.  Peter R. Kellogg, a senior
managing director of Spear, Leeds & Kellogg, L.P., beneficially owns 2,940,222
shares of common stock of the Registrant (approximately 21% of the outstanding
shares of common stock of the Registrant).  Charles Kirkland Kellogg, the son of
Peter R. Kellogg, is a director of the Registrant.


Item 5.    Other Events

     The Registrant entered into an amendment to a lease for space at 90 Hudson
Street, Jersey City, New Jersey previously filed with the Commission.  The
amendment and the amended lease are filed as exhibits hereto.

             Pro Forma Condensed Consolidated Financial Statements

                             Introductory Paragraph

  In June 1999, the Company sold 100% of its membership interests in Equitrade
Partners, L.L.C. ("Equitrade") to Spear, Leeds & Kellogg Specialists LLC. Under
the terms of the sale agreement, all intercompany assets and liabilities were
cash settled and the Company repaid its $15,000,000 loan payable to Spear,
Leeds & Kellogg, LP. The following unaudited pro forma condensed consolidated
financial statements give effect to the sale agreement as if it occurred as of
June 1, 1995. The unaudited pro forma condensed consolidated financial
statements are not necessarily indicative of what the financial results would
have been if Equitrade had been sold on June 1, 1995 and are not necessarily
indicative of future results. These unaudited pro forma condensed consolidated
financial statements are based on certain assumptions which are set forth
below.

  The following unaudited pro forma condensed consolidated financial statements
give effect to the adjustments to record the sale of the Company's membership
interests in Equitrade. The adjustments comprise the elimination of the
operations, assets and liabilities of Equitrade, receipt of cash of
approximately $82,400,000 (consisting of gain on sale, return of capital and
net repayment of notes receivable), recording the after-tax gain of
approximately $20,500,000, accruing income taxes payable of $15,500,000 and the
bonus to the Company's chief executive officer of approximately $6,400,000, and
additional adjustments which are directly attributable to the sale. Such pro
forma information is based upon the historical consolidated statement of
financial condition of the Company and Equitrade as of February 28, 1999.

  The unaudited pro forma condensed consolidated statements of income give
effect to the sale of the Company's membership interests in Equitrade as if the
sale had occurred as of June 1, 1995. Therefore, the revenues and expenses of
Equitrade subsequent to June 1, 1995 have been eliminated and additional
adjustments which are directly attributable to the sale have been recorded. The
unaudited pro forma condensed consolidated statements of income are presented
for the three years ended May 31, 1996, 1997, and 1998 and for the nine months
ended February 28, 1998 and 1999.

  These unaudited pro forma condensed consolidated financial statements should
be read in conjunction with the Company's historical financial statements and
notes thereto included elsewhere in this registration statement.

(1) The pro forma condensed consolidated statement of income has been adjusted
   to eliminate the income and expenses of Equitrade as well as the related
   income tax at the statutory rate of 43%. An additional adjustment to reduce
   NDBG's compensation and benefits expense of approximately $1,042,000 has
   been made to reflect the reduction in the bonus to NDBG's CEO which would
   have resulted if the net income of Equitrade were not included in the
   consolidated results of NDBG. Income from continuing operations does not
   reflect the gain recognized on sale of Equitrade.

(1) The pro forma condensed consolidated statement of income has been adjusted
   to eliminate the income and expenses of Equitrade as well as the related
   income tax at the statutory rate of 43%. An additional adjustment to reduce
   NDBG's compensation and benefits expense of approximately $396,000 has been
   made to reflect the reduction in the bonus to NDBG's CEO which would have
   resulted if the net income of Equitrade were not included in the
   consolidated results of NDBG. Income from continuing operations does not
   reflect the gain recognized on sale of Equitrade.

to NDB, on behalf of the NDB Group, and the Members' Representative, on behalf
of the Seller Individuals, an unaudited balance sheet of the Company as of the
Closing Date, which balance sheet shall be prepared in accordance with GAAP and

of Schedule 3.12 from June 1, 1999 through the Closing Date, in each case as of
the Closing Date (collectively with such balance sheet, the "Final Closing Date
Balance Sheet"). The Buyer shall deliver reasonably detailed calculations with
the Final Closing Date Balance Sheet showing adjustments to the Closing Date
Balance Sheet. Within 10 Business Days after receipt of such Final Closing Date
Balance Sheet, NDB, on behalf of the NDB Group, or the Members' Representative,
on behalf of the Seller Individuals, may deliver to the Buyer a notice that
explains with reasonable specificity (with reasonably detailed calculations) any
adjustments to the Final Closing Date Balance Sheet that Sellers request. Upon
prior written request of NDB or the Members' Representative made to the Buyer,
the Buyer will provide NDB and the Members' Representative with reasonable
access during normal business hours to relevant working papers used in the
preparation of the Final Closing Date Balance Sheet. If NDB or the Members'
Representative does not deliver such notice to the Buyer within such time,
Sellers shall be deemed to have waived any right to contest or otherwise adjust
the Final Closing Date Balance Sheet. If NDB or the Members' Representative
provides the notice described in the preceding sentence, Sellers and the Buyer
will use their reasonable best efforts to reach a mutual agreement on any
appropriate adjustments to be made to the Final Closing Date Balance Sheet
within 10 Business Days of the receipt of such notice. If Sellers and the Buyer
are unable to resolve any disputes within ten (10) Business Days of receipt of
notice from NDB or the Members' Representative, then such disputes shall be
referred to a nationally recognized independent certified public accounting firm
mutually agreed upon by the Buyer, NDB and the Members' Representative. The
accounting firm to which such disputes are referred shall, within twenty (20)
Business Days after such disputes shall have been referred to it deliver to
Sellers and the Buyer a written report indicating its views on the item or items
in dispute and its resolution thereof. The determination of the independent
accounting firm pursuant to the terms of this Section 2.5 shall be final and
binding on the Buyer and the Sellers in the absence of manifest error (so long
as the Buyer has complied with its obligation to provide NDB and the Members'
Representative, upon their prior written request, with reasonable

                                       10

access during normal business hours to relevant working papers in accordance
with this Section 2.5). In the event that a dispute regarding the Final Closing

above, the cost thereof shall be divided equally among the Seller Individuals
(to be paid by the Members' Representative), NDB Group (to be paid by NDB) and
the Buyer.

is provided in Section 2.3 hereof on the Settlement Date, or at such other place
and time and at such other time and date as may be mutually agreed upon in
writing by the Buyer, NDB and the Members' Representative. At the Supplemental
Closing, the Buyer shall pay (1) NDB, on behalf of the NDB Group, by wire
transfer of immediately available funds, the amount, if any, by which the
Adjusted NDB Group Purchase Price exceeds the amount of the Estimated NDB Group
Purchase Price, plus any accrued and unpaid interest on its Capital Account from
June 1, 1999 through the Closing Date and (2) each Seller Individual, by wire
transfer of immediately available funds, the amount, if any, by which the
Adjusted Seller Individuals Purchase Price exceeds the Estimated Seller
Individuals Purchase Price, plus any accrued and unpaid interest on the Capital
Account of any Seller identified in the last paragraph of Schedule 3.12 from
June 1, 1999 through the Closing Date. In the event that the amount of the
Estimated Purchase Price shall exceed the Adjusted Purchase Price, NDB (on
behalf of the NDB Group) and the Seller Individuals shall pay to the Buyer at
the Supplemental Closing, by wire transfer of immediately available funds, the
amount of such excess; in such event, payments by NDB and the Seller Individuals
shall be pro rata on the basis of the portion of the Purchase Price received by
the NDB Group and each respective Seller Individual, unless the adjustment is
other than pro rata as provided in a written notice from the Buyer to NDB and
the Members' Representative.

by such Seller to the Buyer in connection with this Agreement contains any
untrue statement of a material fact or omits to state a material fact necessary
to make the statements not misleading in light of the circumstances under which
they were made. There is no fact known to such Seller which materially adversely
affects, or in the future may (so far as can be reasonably foreseen) materially
adversely affect, the financial condition, business, assets, results of
operations, properties, or prospects of the Company which has not been set forth
in this Agreement or the schedules hereto.

                  SECTION 3.22. Finders' Fees. There is no investment banker,

                                --------------
all "employee benefit plans", as defined in Section 3(3) of ERISA, and all other
employee benefit arrangements, policies or payroll practices, including, without
limitation, severance pay, sick leave, vacation pay, salary continuation for
disability, retirement, deferred compensation, bonus, stock purchase, stock
option, hospitalization, medical insurance, life insurance, tuition
reimbursement and scholarship programs maintained for the benefit of or to which
contributions are made on behalf of current or former employees of the Company
and the Subsidiaries. Such plans, policies, programs and practices shall
hereinafter be referred to as the "Company Benefit Plans".

                  (b) None of the Company Benefit Plans is a "multiemployer
plan", as defined in Section 3(37) of ERISA ("Multiemployer Plan"). Neither the
Company nor or any trade or business (whether or not incorporated) which is or
has ever been

                                       19
<PAGE>

treated as a single employer with the Company under Section 414(b), (c), (m) or
(o) of the Code ("ERISA Affiliate") has incurred any liability due to a complete
or partial withdrawal from a Multiemployer Plan or due to the termination or
reorganization of a Multiemployer Plan, except for any such liability which has
been satisfied in full, and no events have occurred and no circumstances exist
that could reasonably be expected to result in any such liability to the
Company. Neither the Company nor any ERISA Affiliate has engaged in any
transaction described in Section 4212 of ERISA that could result in liability to
the Company with respect to any Multiemployer Plan.

                  (c) None of the Company Benefit Plans is a "single-employer
plan", as defined in Section 4001(a)(15) of ERISA ("Pension Plan"). With respect
to each Pension Plan sponsored by, or to which contributions are required of,
any ERISA Affiliate, there does not exist any accumulated funding deficiency
within the meaning of Section 412 of the Code or Section 302 of ERISA, whether
or not waived. Neither the Company nor any ERISA Affiliate has any outstanding
liability under Section 4062 of ERISA to the PBGC or to a trustee appointed
under Section 4042 of ERISA, and no events have occurred and no circumstances
exist that could reasonably be expected to result in any such liability to the
Company.

                  (d) Each of the Company Benefit Plans that are intended to
qualify under Section 401(a) of the Code, and the trusts maintained pursuant
thereto, have been determined to be exempt from federal income taxation under
Section 501 of the Code by the Internal Revenue Service (or remain within the
remedial amendment period for obtaining an initial determination of exemption
from tax), and no material event has occurred with respect to the operation of
any such Company Benefit Plans which could cause the loss of such qualification
or exemption or the imposition of any liability, penalty or tax under ERISA or
the Code.

                  (e) All contributions (including all employer contributions
and employee contributions) required to have been made under the Company Benefit
Plans or by law to any funds or trusts established thereunder or in connection
therewith have been made by the due date thereof (including any valid
extension), and all contributions for any period ending on or before the Closing
which are not yet due will have been paid or accrued by the Closing.

                  (f) Except as set forth in Schedule 3.23(f), there has been no
material violation of ERISA or the Code with respect to the filing of applicable
documents, notices or reports (including, but not limited to, annual reports
filed on IRS Form 5500) regarding the Company Benefit Plans with the Department
of Labor and the Internal Revenue Service, or the furnishing of such

                                       20
<PAGE>

required documents to the participants or beneficiaries of the Company Benefit
Plans.

                  (g) True, correct and complete copies of the following
documents, with respect to each of the Company Benefit Plans, have been
delivered to the Buyer: (i) the plan and its related trust document, including
any amendments thereto; (ii) the most recent IRS Forms 5500 filed with the
Internal Revenue Service; (iii) summary plan descriptions; and (iv) written
communications to employees relating to the Company Benefit Plans.

                  (h) Except as set forth in Schedule 3.23(h), there are no
pending actions, claims or lawsuits which have been asserted or instituted
against the Company Benefit Plans, the assets of any of the trusts under such
Company Benefit Plans or the Company Benefit Plans' sponsor or the Company
Benefit Plans' administrator, or against any fiduciary of the Company Benefit
Plans with respect to such Company Benefit Plans (other than routine benefit
claims), and neither the Company nor any ERISA Affiliate has knowledge of any
facts which could reasonably form the basis for any such actions, claims or
lawsuits.

                  (i) Except as set forth in Schedule 3.23(i), the Company
Benefit Plans have been maintained, in all material respects, in accordance with
their express terms and with all provisions of ERISA and the Code (including
rules and regulations thereunder) and other applicable federal and state laws
and regulations, and neither the Company, nor any "party in interest" or
"disqualified person" with respect to the Company Benefit Plans has engaged in a
"prohibited transaction", as defined in Section 4975 of the Code or Section 406
of ERISA, or taken any actions, or failed to take any actions, which could
reasonably result in any material liability under ERISA or the Code. Except as
set forth in Schedule 3.23(i), no fiduciary has any liability for breach of
fiduciary duty or any other failure to act or comply in connection with the
administration or investment of the assets of any of the Company Benefit Plans,
and neither the Company nor any ERISA Affiliate has knowledge of any facts which
could reasonably form the basis for any such liability.

                  (j) The Company and each ERISA Affiliate that maintains a
"group health plan", as defined in Section 4980B of the Code, has complied in
all material respects with the notice and coverage continuation requirements of
Section 4980B of the Code and Section 601 of ERISA, and the regulations
thereunder ("COBRA"). None of the Company Benefit Plans provide retiree health
or life insurance benefits except as may be required by COBRA or at the expense
of the participant or the participant's beneficiary.

                  (k) Except as otherwise provided in this Agreement, neither
the execution and delivery of this Agreement nor the consummation of the
transactions contemplated hereby will: (i) result in any payment becoming due to
any current or former

                                       21
<PAGE>

employee of the Company, (ii) increase any benefits otherwise payable under any
of the Company Benefit Plans or (iii) result in the acceleration of the time of
payment or vesting of any benefits provided under any of the Company Benefit
Plans.

                  (l) The Company has no contract, plan or commitment, whether
legally binding or not, to create any additional employee benefit plan or to
modify any existing Company Benefit Plans, except with respect to changes
required by ERISA, the Code or other applicable law.

                  (m) There has been no mass layoff or plant closing as defined
by the Worker Adjustment and Retraining Notification Act or any similar state or
local "plant closing" law with respect to the employees of the Company.

bargaining agreement and there are no labor or collective bargaining agreements

the Company are represented by any labor organization. No labor organization or
group of employees of the Company has made a pending demand for recognition or
certification, and there are no representation or certification proceedings
presently pending or threatened in writing to be brought or filed with the

                  (c) There are no strikes, work stoppages, slowdowns, lockouts,
material arbitrations or material grievances or other material labor disputes
pending or threatened in writing against or involving the Company. There are no
unfair labor practice charges, grievances or complaints pending or threatened in
writing by or on behalf of any employee or group of employees of the Company
which, if individually or collectively resolved against the Company, could
result in a material liability.

                  (d) There are no complaints, charges or claims against the
Company pending or threatened in writing to be brought or filed with any public
or governmental authority, arbitrator, court or other Governmental Entity based
on, arising out of, in connection with, or otherwise relating to the employment
or termination of employment by the Company of any individual.

contained herein) as shall be valid and enforceable under such applicable law.

are entitled to all refunds and deductions for all taxable periods relating to
the Company ending on or prior to the Closing Date, except for charges, reserves
and accrual of liabilities reflected on the Closing Date Balance Sheet and

to be prepared and file or cause to be filed all Tax Returns for the Company due
prior to the Closing Date.

                  (c) Without the prior written consent of the Buyer, neither
Sellers nor the Company shall, to the extent it may affect or relate to the

file any amended Tax Return, enter into any closing agreement, settle any Tax
claim or assessment, surrender any right to claim a Tax refund, consent to any

                  (d) Without the prior written consent of NDB, on behalf of the
NDB Group, and the Members' Representative, on behalf of the Seller Individuals,

Members' Representative, on behalf of the Seller Individuals, however, shall not
be unreasonably withheld.

                  (e) The Company shall not make any payment of Taxes to any

amount of federal income tax on such gain equal to such gain multiplied by the
highest marginal rate of tax imposed by the Code on corporations for the taxable
year in which the sale occurs.

                  SECTION 9.4. Other Tax Matters. All transfer, documentary,
                               -----------------
sales, use, stamp, registration, value added and other such Taxes and fees
arising out of the transactions contemplated by this Agreement (including any
New York Real Estate Transfer Tax, New York City Real Property Transfer Tax and
any similar Tax imposed in other states or subdivisions) shall be borne and paid
by Sellers when due, and Sellers will, at their own expense, file all necessary
Tax returns and other documentation with respect to all such Taxes and fees,
and, if required by applicable law, the Buyer will, and will cause its
Affiliates to, join in the execution of any such Tax returns and other
documentation.

                  SECTION 9.5. Cooperation on Tax Matters. (a) The Buyer shall
                               --------------------------
prepare or cause to be prepared and file any Tax Returns due after the Closing.
Sellers shall cooperate fully in connection with the preparation and filing of
any such Tax Returns. The Buyer shall notify NDB (on behalf of the NDB Group)

                                       40
<PAGE>

and the Members' Representative of any amounts related to such Tax Returns that
are the responsibility of the Sellers under the provisions of this Article. If
NDB or the Members' Representative, respectively, do not object within 10
Business Days of the receipt of such notice, Sellers shall remit to the Buyer
any such amounts. If NDB or the Members' Representative gives notice to the
Buyer within 10 business days that NDB or the Members' Representative,
respectively objects to the notice, then (a) the parties shall attempt in good
faith to resolve their differences during the ten (10) business day period
following the date of delivery of the notice of objection from the Members'
Representative or NDB (the "Closing Return Resolution Period"), and (b) if the
parties fail to resolve their disagreement during the Closing Return Resolution
Period, each party shall select a representative from a nationally or regionally
recognized accounting firm, and these two individuals shall select a third such
person, and this group of three individuals shall resolve the dispute by a
determination agreed to by a majority of such group within twenty-one (21) days
after the individuals are initially identified in a writing among the parties.
Any resolution of any such dispute entered into in compliance with this
subsection (a) shall also be binding on the parties in the same manner as if a
final judgment or decree had been entered by a court of competent jurisdiction
in the amount of the determination.

                  Sellers and the Buyer shall cooperate fully in connection with
any audit, litigation, or other proceeding with respect to Taxes. The Buyer
shall retain for three years the records and information that are reasonably
relevant to any such audit, litigation or other proceeding.

                  (b) The Buyer and Sellers further agree, upon request, to
use all reasonable efforts to obtain any certificate or other document from any
governmental authority or customer of the Company or any other person as may be
necessary to mitigate, reduce or eliminate any Tax that could be imposed
(including, but not limited to, with respect to the transactions contemplated
hereby).

                  SECTION 9.6. Tax Indemnification. (a) Each Seller Individual
                               -------------------
hereby severally (but not jointly) indemnifies each Buyer Indemnitee against and
agrees to hold each Buyer Indemnitee harmless from any (x) Tax of the Company or
any successor of the Company related to the Tax Indemnification Period for Buyer
Indemnitees, except for charges, reserves and accrual of liabilities reflected
on the Closing Date Balance Sheet and described in Section 9.2(b)(iv), (y) Tax
of the Company or any successor of the Company resulting from a breach of any
provisions of this Article IX, and (z) liabilities, costs, expenses (including,
without limitation, reasonable expenses of investigation and attorneys' fees and
expenses), losses, damages, assessments, settlements or judgments arising out of
or incident to the imposition, assessment, or assertion of any Tax described

                                       41
<PAGE>

in (x) or (y), including those incurred in the contest in good faith in
appropriate proceedings relating to the imposition, assessment or assertion of
any such Tax, and any liability as transferee. The sum of (x), (y) and (z) is
referred to herein as a "Buyer Tax Loss."

                  (b) Each of NDB and SHD hereby guarantees the full payment,
when due, of the obligations of the Seller Individuals provided for in Section
9.6(a) of this Agreement.

                  (c) The Buyer hereby indemnifies each Seller Indemnitee
against and agrees to hold each Seller Indemnitee harmless from any (x) Tax of
the Company or any successor of the Company related to the Tax Indemnification
Period for Seller Indemnitee (other than any Tax properly allocable to any
period ending on or before the Closing Date), (y) Tax of the Company or any
successor of the Company resulting from a breach of any provisions of this
Article IX, and (z) liabilities, costs, expenses (including, without limitation,
reasonable expenses of investigation and attorneys' fees and expenses), losses,
damages, assessments, settlements or judgments arising out of or incident to the
imposition, assessment, or assertion of any Tax described in (x) or (y),
including those incurred in the contest in good faith in appropriate proceedings
relating to the imposition, assessment or assertion of any such Tax, and any
liability as transferee. The sum of (x), (y) and (z) is referred to herein as a
"Seller Tax Loss", provided, however, that Buyer shall have no liability under
this Section 9.6 unless and until the aggregate of all Seller Tax Losses exceeds
the sum of $50,000 (the "Seller's Minimum Amount"), in which event Buyer shall
be liable for all Seller Tax Losses, irrespective of the Seller's Minimum
Amount.

                  (d) For purposes of this Section 9.6, in the case of any Taxes
that are imposed on a periodic basis and are payable for a Tax period that
includes (but does not end on) the Closing Date, the portion of such Tax related
to the portion of such Tax period ending on and including the Closing Date shall
(x) in the case of any Taxes other than gross receipts, sales, withholding, or
use Taxes and Taxes based upon or related to income, be deemed to be the amount
of such Tax for the entire Tax period multiplied by a fraction of the numerator
of which is the number of days in the Tax period ending on and including the
Closing Date and the denominator of which is the number of days in the entire
Tax period, and (y) in the case of any gross receipts, sales, withholdings or
use Taxes or Taxes based upon or related to income, be deemed equal to the
amount which would be payable if the relevant Tax period ended on and included
the Closing Date. The portion of any credits relating to a Tax period that
begins before and ends after the Closing Date shall be determined as though the
relevant Tax period ended on and included the Closing Date.

                                       42

                  (e) A party (the "Indemnified Party") may assert a Claim that
it is entitled to, or may become entitled to, indemnification under this Article
IX by giving written notice of its Claim to the party or parties that are, or
may become, required to indemnify the Indemnified Party (the "Indemnifying
Party"), providing reasonable details of the facts giving rise to the Claim and
a statement of the Indemnified Party's loss in connection with the Claim, to the
extent such loss is then known to the Indemnified Party and, otherwise, an
estimate of the amount of the loss that it reasonably anticipates that it will
incur or suffer. If the Indemnifying Party does not object to the Claim during
the twenty (20) day period following the date of delivery of the Indemnified
Party's notice of its Claim (the "Objection Period"), the Claim shall be
considered undisputed and the Indemnified Party shall be entitled to recover the
amount of its Loss. The fact that a Claim is not disputed by the Indemnifying
Party shall not constitute an admission or create any inference that the
asserted Claim is valid for any purpose other than the indemnity obligation of
the Indemnifying Party as to such Claim pursuant to this Section 9.6.

                  (f) If the Indemnifying Party gives notice to the Indemnified
Party within the Objection Period that the Indemnifying Party objects to the
Claim, then (a) the parties shall attempt in good faith to resolve their
differences during the ten (10) business day period following the date of
delivery of the Indemnifying Party's notice of its objection (the "Resolution
Period"), and (b) if the parties fail to resolve their disagreement during the
Resolution Period, each party shall select a representative from a nationally or
regionally recognized accounting firm, and these two individuals shall select a
third such person, and this group of three individuals shall resolve the dispute
by a determination agreed to by a majority of such group within twenty-one (21)
days after the individuals are initially identified in a writing among the
parties. Any resolution of any such dispute entered into in compliance with this
Section 9.6(f) shall also be binding on the parties in the same manner as if a
final judgment or decree had been entered by a court of competent jurisdiction
in the amount of the determination.

                  (g) In the case of any third party suit ("Third Party Suit"),
the Indemnifying Party shall control the defense of the Third Party Suit, and
shall be fully responsible for the costs of counsel related thereto; provided,
                                                                     --------
however, that the Indemnifying Party shall control the defense of the Third
- -------
Party Suit only if the Indemnifying Party first admits in a writing, which
writing shall be binding on the Indemnifying Party, delivered to the Indemnified
Party that the Indemnifying Party will be obligated, pursuant to Section 9.6
hereof, to indemnify the Indemnified Party for any liability arising out of such
Third Party Suit. The Indemnifying Party shall consult with the Indemnified
Party with respect to the Third Party Suit upon the Indemnified Party's
reasonable request for consultation, and the Indemnified Party

                                       43
<PAGE>

may, at its expense, participate in (but not control) the defense and employ and
pay for counsel separate from the counsel employed by the Indemnified Party. All
parties shall cooperate in the defense of the Third Party Suit.

                  (h) If an Indemnified Party is conducting the defense of a
Third Party Suit, the Indemnified Party shall give the Indemnifying Party at
least fifteen (15) days prior written notice of any proposed settlement or
compromise, during which time the Indemnifying Party may assume the defense of
the Third Party Suit and, if it does so (or if the Indemnifying Party has
already assumed control of such Third Party Suit), the proposed settlement or
compromise may not be made without the Indemnified Party's consent, which shall
not be unreasonably withheld. If an Indemnifying Party does not so assume the
defense of the Third Party Suit, the Indemnified Party may enter into the
proposed settlement. Any settlement or compromise of any Third Party Suit by
either the Indemnifying Party or the Indemnified Party entered into in
compliance with this Section 9.6(h) shall also be binding on the other party in
the same manner as if a final judgment or decree had been entered by a court of
competent jurisdiction in the amount of the settlement or compromise.

                  (i) Any failure by an Indemnified Party to defend a Third
Party Suit shall not relieve the Indemnifying Party of its indemnification
obligations if the Indemnified Party gives the Indemnifying Party at least
thirty (30) days prior written notice of the Indemnified Party's intention not
to defend and affords the Indemnifying Party the opportunity to assume the
defense.

                  (j) The Buyer and Sellers shall jointly control the defense of
any claim that relates to Taxes payable for a Tax period that includes (but does
not end on) the Closing Date.

                  (k) An Indemnifying Party shall not be liable under this
Section 9.6 with respect to any Tax resulting from a claim or demand the defense
of which the Indemnifying Party was not offered the opportunity to assume as
provided under Section 9.6(g) to the extent the Indemnifying Party's liability
under this section is adversely affected as a result thereof. No investigation
by an Indemnified Party or any of its Affiliates at or prior to the Closing Date
shall relieve the Indemnifying Party of any liability hereunder.

                  (l) Any claim of any Buyer Indemnitee (other than the Buyer)
under this section may be made and enforced by the Buyer on behalf of such Buyer
Indemnitee. Any claim under this Section of a Seller Indemnitee related to the
NDB Group rather than a Seller Individual shall be made and enforced only by NDB
on behalf of such Seller Indemnitee. Any claim under this Section of a Seller
Indemnitee related to a Seller Individual shall be made and enforced only by the
Members' Representative on behalf of such Seller Indemnitee.

                  SECTION 9.7. Audits. (a) Buyer shall notify Sellers promptly
                               ------
of any examinations, audits, litigation or other proceedings respecting the
Company with respect to any taxable period ending on or prior to the Closing
Date and Seller Individuals shall have the right to control the conduct of any
such examination, audit, litigation or other proceeding. Buyer shall provide, or
shall cause the Company to provide, Sellers with such assistance and
cooperation, including the execution of powers of attorney, as Sellers may
reasonably request in order to enable Sellers to exercise such control.

                  (b) Buyer shall have the sole right to represent the
Company in any Tax audit or administrative or court proceeding for all taxable
periods ending after the Closing Date, and to employ counsel of choice at its
own expense.

                  (c) Buyer and Seller shall provide timely notice to the other
party (or parties) in writing of any pending or threatened tax audit with
respect to the Company for a taxable period for which the other party may have a
liability under this Article IX. Buyer and Sellers shall furnish each other with
copies of all correspondence received from any Taxing Authority in connection
with any tax audit or information request with respect to such taxable periods.

                  SECTION 9.8. Allocation of Purchase Price. (a) As soon as
                               ----------------------------
practicable after the Closing, the Members' Representative shall deliver a
schedule to the Buyer setting forth on a reasonable basis the federal income tax
basis of all of the assets, properties and business of every kind and
description, wherever located, real, personal or mixed, tangible or intangible
owned by the Company as the same shall exist on the Closing Date (the "Closing
Date Assets"). Within a reasonable amount of time thereafter, the Buyer shall
deliver to the Members' Representative a statement (the "Allocation Statement"),
setting forth the value of all of the Closing Date Assets, which shall be used
for the allocation of the Purchase Price. The Allocation Statement will not be
binding on a Seller to the extent Revenue Ruling 99-6, 1999-6 I.R.B 6, or
similar position of the Internal Revenue Service makes the Allocation Statement
not relevant to such Seller.

                  (b) Any adjustment made with respect to the Purchase Price
of this Agreement shall be allocated in a manner consistent with the methodology
used in preparing the Allocation Statement.

                  (c) The Sellers and the Buyer agree to act in accordance with
the Allocation Statement in the preparation of financial statements and filing
of all tax returns and in the course of any tax audit, tax review or tax
litigation relating thereto.

                  SECTION 9.9. Purchase Price Adjustment. Any amount paid by the
                               -------------------------
Sellers or Buyer under Section 9.6 will be treated either

                                       45
<PAGE>

as an adjustment to the Purchase Price or as a contribution to the Company
unless a Final Determination is inconsistent with such treatment.

                  SECTION 9.10. Survival. Notwithstanding anything in this
                                --------
Agreement to the contrary, the provisions of this Article IX shall survive for
the full period of all applicable statutes of limitations (giving effect to any
waiver, mitigation or extension thereof).

                  Company of its registration as the specialist for any security
                  shall not be deemed a material adverse change unless such
                  security (excluding, for this purpose, BankBoston
                  Corporation), considered singly or in the aggregate with any

                  months ended at the month end immediately prior to the date
                  such registration was lost.

                  Sellers have complied with the covenant set forth in Section
                  7.8.

                                    (ix) The Buyer shall have received the

                  together with a schedule reflecting each Seller's Capital
                  Account and the aggregate Mark to Market-Off Floor Trading

                  Seller identified in the last paragraph of Schedule 3.12 cash

                  government or governmental authority or agency, domestic or

                  Subordinated Loan.

                                    (vii) Spear, Leeds & Kellogg, L.P. shall

                                   ARTICLE XI.

                  SECTION 11.1. Survival. The covenants, agreements,
                                --------
representations and warranties of the parties hereto contained in this Agreement
or in any certificate or other writing delivered pursuant hereto or in
connection herewith shall survive the Closing for a period of one year;
provided, however, that (i) the covenants and agreements contained in Section
- --------  -------
7.4 shall survive for the period set forth therein, (ii) the covenants and
agreements contained in Section 7.7 shall survive for so long as the promissory
notes issued to the Seller Individuals pursuant to Section 2.3(b) of this
Agreement are outstanding, (iii) the covenants, agreements, representations and
warranties contained in Sections 3.23 and 3.24 and Article IX shall survive
until expiration of the statute of limitations applicable to the matters covered

<PAGE>

or extension thereof) and (iv) the representations contained in Sections 3.7,
3.8, 4.5, 5.6 and 5.7 shall survive without limitation as to time.
Notwithstanding the preceding sentence, any covenant, agreement, representation

shall survive the time at which it would otherwise terminate pursuant to the
preceding sentence, if notice of the inaccuracy or breach thereof giving rise to
such right of indemnity shall have been given to the party against whom such
indemnity may be sought prior to such time.

                  SECTION 11.2. Indemnification. (a) Each Seller Individual
                                ---------------
(other than the RSF Group) hereby severally (but not jointly) agrees to
indemnify the Buyer, any Affiliate of the Buyer, or their respective
stockholders, partners, members, directors, officers, agents, employees and
representatives, their successors and assigns and, effective upon the Closing,
the Company (the "Buyer Indemnitees") against and agree to hold each of them
harmless from any and all damages, loss, liability, cost, expense (including
without limitation reasonable expenses of investigation and reasonable
attorneys' fees and expenses in connection with any action, suit or proceeding),
deficiency, interest, penalty, imposition, assessment or fine ("Damages")
reasonably and proximately incurred or suffered by any Buyer Indemnitee arising
out of any misrepresentation or breach of warranty, covenant or agreement made
or to be performed by such Seller Individual pursuant to this Agreement.

                  (b) Each member of the RSF Group hereby severally (but not
jointly) agrees:

                  (i) other than with respect to any representation, warranty,
covenant or agreement covered under Section 11.2(b)(ii), to indemnify the Buyer
Indemnitees against and agree to hold each of them harmless from any Damages
reasonably and proximately incurred or suffered by any Buyer Indemnitee arising
out of any misrepresentation or breach of warranty, covenant or agreement made
or to be performed by such member of the RSF Group pursuant to this Agreement;
and

                  (ii) with respect to any representation, warranty, covenant or
agreement contained in Article III, to indemnify any Buyer Indemnitee and hold
it harmless to the extent any Seller Individual (other than the RSF Group) is
unable (due to bankruptcy or for any other reason) to satisfy its obligations
under this Section 11.2; provided, however, that the RSF Group shall have no
                         --------  -------
indemnity obligations as to Sections 3.2, 3.3, 3.4, 3.5 (with respect to other
Seller Individuals), 3.7, 3.12, 3.14, 3.19, 3.21, 3.22 and 3.26. The Buyer
agrees to use its reasonable efforts to collect amounts owed by a Seller
Individual under Section 11.2(a) prior to availing itself of this Section
11.2(b)(ii), and agrees to keep each member of the RSF Group reasonably informed
of such efforts. The RSF Group shall be subrogated to the rights of an
Indemnified Party to the extent of

                                       52
<PAGE>

any payment made to such Indemnified Party pursuant to this Section 11.2(b)(ii).

                  (c) NDB and SHD hereby jointly and severally agree:

                  (i) other than with respect to any representation, warranty,
covenant or agreement covered under Section 11.2(c)(ii), to indemnify the Buyer
Indemnitees against and agree to hold each of them harmless from any Damages
reasonably and proximately incurred or suffered by any Buyer Indemnitee arising
out of any misrepresentation or breach of warranty, covenant or agreement made
or to be performed by NDB or SHD pursuant to this Agreement; and

                  (ii) with respect to any representation, warranty, covenant or
agreement contained in Article III or Article IV, to indemnify any Buyer
Indemnitee and hold it harmless to the extent any Seller Individual is unable
(due to bankruptcy or for any other reason) to satisfy its obligations under
this Section 11.2; provided, however, that NDB and SHD shall have no indemnity
                   --------  -------
obligations as to Section 3.2, 3.3, 3.4, 3.5 (with respect to Seller
Individuals), 3.7, 3.12, 3.14, 3.19, 3.21, 3.22, 3.26, 4.1, 4.2, 4.5, 4.7, 4.8
and 4.12. The Buyer agrees to use its reasonable efforts to collect amounts owed
by a Seller Individual under Section 11.2(a) prior to availing itself of this
Section 11.2(c)(ii), and agrees to keep NDB (on behalf of the NDB Group)
reasonably informed of such efforts. NDB (on behalf of the NDB Group) shall be
subrogated to the rights of an Indemnified Party to the extent of any payment
made to such Indemnified Party pursuant to this Section 11.2(c)(ii).

                  (d) The Buyer hereby agrees to indemnify each Seller, any
Affiliate of such Seller, or their respective stockholders, partners, members,
directors, officers, agents, employees and representatives (the "Seller
Indemnitees") against and agrees to hold each of them harmless from any and all
Damages reasonably and proximately incurred or suffered by any Seller Indemnitee
arising out of any misrepresentation or breach of warranty, covenant or
agreement made or to be performed by the Buyer pursuant to this Agreement.

                  SECTION 11.3. Procedures. The party seeking indemnification
                                ----------
under Section 11.2 (the "Indemnified Party") agrees to give prompt notice to the
party against whom indemnity is sought (the "Indemnifying Party") of the
assertion of any claim, or the commencement of any suit, action or proceeding,
or the existence of any liability, in respect of which indemnity may be sought
under such Section. The failure by an Indemnified Party to so notify an
Indemnifying Party will not relieve the Indemnifying Party of any
indemnification responsibility under this Article X, except to the extent, if
any, that such failure materially prejudices the ability of the Indemnifying
Party to defend such claim, suit, action or proceeding (brought by a Person not
a party to this Agreement). The Indemnifying Party

                                       53
<PAGE>

may in its discretion participate in and control the defense, compromise or
settlement of any such claim, suit, action or proceeding at its own expense. The
Indemnified Party shall not settle any claim, litigation or proceeding without
the consent of the Indemnifying Party, such consent not to be unreasonably
withheld.

Individuals.

                  (a) Notwithstanding any other provision of this Agreement, the
Sellers' indemnification obligations under Section 9.6 and Section 11.2 shall on
a cumulative basis be limited to an amount equal to the Purchase Price.

                  (b) Notwithstanding any other provision of this Agreement,
each Seller's indemnification obligations under Section 9.6 and Section 11.2
shall on a cumulative basis be limited to that share of the Purchase Price
received by it.

                  (c) Notwithstanding any other provision of this Agreement, the
Sellers, collectively, shall have no obligation to make any payment under
Sections 9.6 or 11.2 unless the aggregate amount to which all Buyer Indemnitees
are entitled by reason of all claims under Sections 9.6 or 11.2 exceeds $50,000;
provided, however, that the Sellers shall be obligated to make all payments
- --------  -------
under Sections 9.6 and 11.2 to the extent the aggregate amount to which all
Buyer Indemnitees are entitled by reason of all claims against the Sellers under
Section 9.6 and all claims under Section 11.2 exceeds $50,000.

                  (d) The RSF Group's indemnification obligations pursuant to
Section 9.6 and Section 11.2 shall on a cumulative basis be limited to
$2,000,000; provided, however, that this Section 11.4(d) shall not be applicable
to any indemnification obligations arising out of or relating to the
representations and warranties contained in Section 4.5.

                  (e) Payments by Sellers pursuant to Section 9.6 and Section
11.2 shall be limited in the aggregate to the amount of any Damages and Buyer
Tax Loss that remain after deducting therefrom any direct tax benefit to the
Buyer and any insurance proceeds and any indemnity, contribution or other
similar payment actually received by the Buyer from any third party with respect
thereto.

                  (f) Except as otherwise provided in this Agreement,
indemnification for obligations related to the tax matters is covered by Article
IX.

                  (g) The Buyer hereby acknowledges and agrees that its
exclusive remedy with respect to any and all claims relating to the subject
matter of this Agreement and the transactions contemplated hereby shall be
pursuant to the indemnification

                                       54
<PAGE>

provisions set forth in Articles IX and XI of this Agreement, except for
equitable relief; provided, that nothing contained herein shall limit the right
                  --------
of any party to exercise or enforce (i) any right of contribution available
under any law, rule or regulation from any other party; (ii) any rights under
any other agreement entered into between the parties hereto, including, without
limitation, the Promissory Notes and the letter agreements related thereto; or
(iii) any cause of action that may exist, not based upon breach of contract, for
fraud.

                  (h) Any notices to be given to any Seller Individual may be
given to the Members' Representative, on behalf of such Seller Individual.

                  Closing shall not have been consummated on or before July 15,

                  Representative and the Buyer);

                  Group), the Members' Representative or the Buyer if there
                  shall be any law or regulation that makes consummation of the
                  transactions contemplated hereby illegal or otherwise
                  prohibited or if consummation of the transactions contemplated
                  hereby would violate any nonappealable final order, decree or
                  judgment of any court or governmental body having competent
                  jurisdiction;

                                    (iv) by the Buyer or NDB if NDB's board of
                  directors does not approve this Agreement by May 20, 1999; or

                                    (v) by NDB (on behalf of the NDB Group), the
                  Members' Representative or the Buyer if any condition to such
                  party's obligations hereunder becomes incapable of fulfillment
                  through no fault of such party and is not waived by such
                  party.

The party desiring to terminate this Agreement shall give notice of such

agreement contained herein, such party shall be fully liable for any and all
Damages incurred or suffered by the other party as a result of such failure or
breach; provided, further, that a termination pursuant to 12.1(iv) shall be
        --------
deemed not to be a termination described in any of clause (A), (B) or (C) of
this sentence. The provision of Section 14.3 shall survive any termination
hereof pursuant to Section 12.1.

                                  ARTICLE XIII.

event of the issuance of any certificate for Landlord's Work which is temporary
as the result of the non-completion of any items for which Landlord is
responsible as part of Landlord's Work, Landlord shall obtain a permanent
certificate as expeditiously as possible.  If, after Tenant has commenced doing
business from the Demised Premises, Tenant is prevented by order of the code
enforcement official having jurisdiction over the Demised Premises, from legally
occupying the Demised Premises for the Permitted Uses as the result of
Landlord's failure to obtain such permanent certificate due to the non-
completion of any items for which Landlord is responsible as part of Landlord's
Work, then in addition to all other rights and remedies in this Lease and at
law, Fixed Rent and Additional Charges for Real Estate Taxes and Operating

equal to the period Tenant was prevented from so using the Demised Premises.

that in

imposition, license fee or charge wholly or partially as a capital levy or
otherwise on the rents received therefrom, or (b) any other such additional or

imposed in lieu of real estate taxes, assessments and special assessments, "Real
Estate Taxes" shall not be deemed to include (i) Landlord's gross personal and

gains, succession, capital stock, excise, excess profit, foreign ownership or
control, payroll, mortgage recording or stamp tax, or (ii) provided Tenant has
paid all Rent when due, any late penalty or interest as the result of late
payment of such Real Estate Taxes by Landlord. Nothing contained herein shall be

Person, and any check received by Landlord shall be deemed received subject to

payment in question when required under this Lease.

lesser amount than the correct Rent shall be deemed to be other than a payment
on account, nor shall any endorsement or statement on any check or any letter

Landlord may accept such check or payment without prejudice to Landlord's right
to recover the balance or pursue any other remedy in this Lease or at law
provided.

     3.04.  If Tenant is in arrears in payment of Rent, Tenant waives Tenant's

request by Tenant as to the items to which any such payments shall be credited.

any check tendered by Tenant to Landlord is returned for insufficient funds,
Tenant shall pay to Landlord, in addition to the charge imposed by the preceding
sentence, a fee of $25.00.  Any such Late Charges if not previously paid shall,
at the option of the Landlord, be added to and become part of the next

have the right to submit such dispute to arbitration in accordance with the
provisions of Article 36 of this Lease, provided however that Tenant's right to
submit such matter to arbitration shall be conditioned upon Tenant having first

liability whatsoever to Tenant or any other party therefor, Landlord shall use
reasonable efforts to avoid exposing Tenant's Data Center (as hereinafter
defined) to water hazards by reason of the resulting build-out on the seventh
floor area above the Data Center.

     5.04.  Landlord reserves the right, at any time and from time to time, to
increase, reduce or change the number, type, size, location, elevation, nature
and use of any of the Common Areas and the Building and any other buildings and
other improvements on the Land consistent with a first class office building,
including, without limitation, the right to move and/or remove same, provided
same shall not unreasonably block or interfere with Tenant's use of the Demised
Premises and means of ingress or egress to and from the Demised Premises. In the
event that any such work or repairs shall require Tenant to either: switch to
backup power, or vacate the Demised Premises, Landlord shall, except in cases of
emergency where such notice is not practicable, provide Tenant with not less
than twenty-five (25) days prior notice of such work or repair to permit Tenant
to coordinate utilization of its backup equipment and facilities, if required.

                 ARTICLE 6 - TAX AND OPERATING EXPENSE PAYMENTS


     6.01.  Tenant shall pay to Landlord, as hereinafter provided, Tenant's
Fraction of the Real Estate Taxes.  Tenant's Fraction of the Real Estate Taxes
shall be the Real Estate Taxes in respect of the Building for the period in
question, less the Real Estate Taxes attributable to the Base Year, multiplied
by the Tenant's Fraction, plus the Real Estate Taxes in respect of the Land for
the period in question, less the Real Estate Taxes attributable to the Base
Year, multiplied by the Tenant's  Fraction.  If any portion of the Building
shall be exempt from all or any part of the Real Estate Taxes, then for the
period of time when such exemption is in effect, the Floor Space on such exempt
portion shall be excluded when making the above computations in respect of the
part of the Real Estate Taxes for which such portion shall be exempt.  Landlord
shall reasonably estimate the annual amount of Tenant's Fraction of the Real
Estate Taxes (which estimate may be changed by Landlord at any time and from
time to time), and Tenant shall pay to Landlord 1/12th of the amount so
estimated on the first day of each month in advance.  Tenant shall also pay to
Landlord on demand from time to time the amount which, together with said
monthly installments, will be sufficient in Landlord's estimation to pay
Tenant's Fraction of any Real Estate Taxes thirty (30) days prior to the date
when such Real Estate Taxes shall first become due.  When the amount of any item
comprising Real Estate Taxes is finally determined for a real estate fiscal tax
year, Landlord shall submit to Tenant a statement in reasonable detail of the
same, and the figures used for computing Tenant's Fraction of the same, and if
Tenant's Fraction so stated is more or less than the amount theretofore paid by
Tenant for such item based on Landlord's estimate, Tenant shall pay to Landlord
the deficiency within ten (10) days after submission of such statement, or
Landlord shall refund to Tenant the excess, or at Landlord's option, apply same
to future installments of Real Estate Taxes due hereunder, with the balance of
any such overpayment by Tenant, if any, remaining after such credit to Tenant to
be refunded to Tenant within ten (10) days of Landlord's statement showing such
overpayment.  Any Real Estate Taxes for a real estate fiscal tax year, a part of
which is included within the Term and a part of which is not so included, shall
be apportioned on the basis of the number of days in the real estate fiscal tax
year included in the Term, and the real estate fiscal tax year for any
improvement assessment will be deemed to be the one-year period commencing on
the date when such assessment is due, except that if any improvement assessment
is payable in installments, the real estate fiscal tax year for each installment
will be deemed to be the one-year period commencing on the date when such
installment is due.  The above computations shall be made by Landlord in
accordance with generally accepted accounting principles, and the Floor Space
referred to will be based upon the average of the Floor Space in existence on
the first day of each month during the period in question.  In addition to the
foregoing, Tenant shall be responsible for any increase in Real Estate Taxes
attributable to assessments for improvements installed by or for the account of
Tenant at the Demised Premises.  If the Demised Premises are not separately
assessed, the amount of any such increase shall be determined by reference to
the records of the tax assessor.

     6.02.  Tenant shall pay to Landlord, as hereinafter provided, Tenant's
Fraction of the Operating Expenses.  Tenant's Fraction of the Operating Expenses
shall be the Operating Expenses for the period in question, less the Operating
Expenses for the Base Year, multiplied by Tenant's Fraction.  Landlord shall
reasonably estimate Tenant's annual Fraction of the

                                       12
<PAGE>

Operating Expenses (which estimate may be reasonably changed by Landlord from
time to time), and Tenant shall pay to Landlord 1/12th of the amount so
estimated on the first day of each month in advance. If at any time Landlord
changes its estimate of Tenant's Fraction of the Operating Expenses for the then
current Calendar Year or partial Calendar Year, Landlord shall give notice to
Tenant of such change and within ten (10) days after such notice Landlord and
Tenant shall adjust for any overpayment or underpayment during the prior months
of the then current Calendar Year or partial Calendar Year. After the end of
each Calendar Year, including any partial Calendar Year at the beginning of the
Term, and after the end of the Term, Landlord shall submit to Tenant a statement
in reasonable detail stating Tenant's Fraction of the Operating Expenses for
such Calendar Year, or partial Calendar Year in the event the Term shall begin
on a date other than a January 1st and/or end on a date other than a December
31st, as the case may be, and stating the Operating Expenses for the period in
question and the figures used for computing Tenant's Fraction, and if Tenant's
Fraction so stated for such period is more or less than the amount paid for such
period, Tenant shall pay to Landlord the deficiency within ten (10) days after
submission of such statement, or Landlord shall refund to Tenant the excess, or
at Landlord's option, apply same to future installments of Operating Expenses
due hereunder, with the balance of any such overpayment by Tenant, if any,
remaining after such credit to Tenant to be refunded to Tenant within ten (10)
days of Landlord's statement showing such overpayment. All computations shall be
made in accordance with generally accepted accounting principles. Landlord's
statement shall be substantially in the form of Exhibit M attached hereto.

     6.03. Landlord shall, within thirty (30) days after written request from
Tenant (given no later than sixty (60) days after the issuance of the Landlord's
statement of Real Estate Taxes or Operating Expenses pursuant to Section 6.01 or
6.02 hereof which Tenant desires to review), provide Tenant with such
information as Tenant may reasonably request to permit Tenant to verify the
charges first appearing in such statement including, without limitation access
to and review of  Landlord's relevant books, records and other financial
information.  Each such statement given by Landlord pursuant to Section 6.01 or
Section 6.02 shall be conclusive and binding upon Tenant unless before the date
which is one hundred fifty (150) days after the receipt of such statement,
Tenant shall notify Landlord in writing that it disputes the correctness of the
statement or that Landlord has failed to provide Tenant with the relevant,
books, records or other financial information reasonably requested by Tenant,
specifying the particular respects in which the statement is claimed to be
incorrect or which books, records or information has not been furnished. Upon
the furnishing of such books, records, or information, each such statement given
by Landlord pursuant to Section 6.01 or Section 6.02 shall be conclusive and
binding upon Tenant unless before the date which is sixty (60) after the receipt
of such books, records or information, Tenant shall notify Landlord in writing
that it disputes the correctness of the statement  If such dispute is not
settled by agreement, either party may submit the dispute to arbitration as
provided in Article 36.  Pending the determination of such dispute by agreement
or arbitration as aforesaid, Tenant shall, within ten (10) days after receipt of
such statement, pay the Additional Charges in accordance with such statement,
without prejudice to Tenant's or Landlord's position.  If the dispute shall be
determined in Tenant's favor, Landlord shall reimburse Tenant the amount of
Tenant's overpayment resulting from compliance with, and if such overpayment is
the result of an overestimation by Landlord of any Additional Charge by more
than five percent (5%), such

                                       13
<PAGE>

overpayment shall be reimbursed to Tenant, within ten (10) days after such
determination, together with interest thereon at the Prime Rate as announced in
the Wall Street Journal (or a successor index reasonably selected by Landlord)
plus two percent (2%), per annum, or at Landlord's option, apply same to future
installments of Operating Expenses due hereunder, with the balance of any such
overpayment by Tenant, if any, remaining after such credit to Tenant to be
refunded to Tenant within ten (10) days of Landlord's statement showing such
overpayment.

  6.04.  In the event the Building ceases to be covered by the Long Term Tax
exemption granted pursuant to the Financial Agreement with the City of Jersey
City, dated May 13, 1998, as the result of a breach of such Financial Agreement
by Landlord or a Superior Lessor, not caused by a default or breach by Tenant,
then Real Estate Taxes which cease to be covered by such exemption shall be
deemed to be equal to the payments which would have been made under said
Financial Agreement had such Financial Agreement not been terminated early as
the result of such breach, as reasonably determined by Landlord.

                            ARTICLE 7 - COMMON AREAS


     7.01. Subject to the provisions of Section 5.04, Landlord will operate,
manage, equip, light, repair and maintain, or cause to be operated, managed,
equipped, lighted, repaired and maintained, the Common Areas for their intended
purposes.  Landlord reserves the right, at any time and from time to time, to
construct within the Common Areas kiosks, fountains, aquariums, planters, pools
and sculptures, and to install vending machines, telephone booths, benches and
the like consistent with a first class office building, provided same shall not
unreasonably block or interfere with Tenant's means of ingress or egress to and
from the Demised Premises.

     7.02.  Tenant and its subtenants and concessionaires, and their respective
officers, employees, agents, customers and invitees, shall, subject to the
provisions of this Lease, have the non-exclusive right, in common with Landlord
and all others to whom Landlord has granted or may hereafter grant such right,
but subject to the Rules and Regulations, to use the Common Areas.  Landlord
reserves the right, at any time and from time to time, to close temporarily all
or any portions of the Common Areas when in Landlord's reasonable judgment any
such closing is necessary or desirable (a) to make repairs or changes or to
effect construction, (b) to prevent the acquisition of public rights in such
areas, (c) to discourage unauthorized parking, or (d) to protect or preserve
natural persons or property. Landlord may do such other acts in and to the
Common Areas as in its judgment may be desirable to improve or maintain same.
In all such events, such repairs and changes shall be commenced and prosecuted
diligently by Landlord in a good and workmanlike manner and with as little
interference as practicable with Tenant's access to and use of the Building and
the Demised Premises. Nothing contained herein shall be construed, however, as
requiring Landlord to perform such work at times other than Monday through
Friday Business Days and during Business Hours except in cases of emergency. In
the event that any such work or repairs shall require Tenant to either: switch
to backup power, or vacate the Demised Premises, Landlord shall, except in cases
of emergency where such notice is not practicable, provide Tenant

                                       14
<PAGE>

with not less than twenty-five (25) days prior notice of such work or repair to
permit Tenant to coordinate utilization of its backup equipment and facilities,
if required.

     7.03.  Tenant agrees that it, any subtenant or licensee and their
respective officers, employees, contractors and agents will park their
automobiles and other vehicles only where and as permitted by Landlord.  Tenant
will, if and when so requested by Landlord, furnish Landlord with the license
numbers of any vehicles of Tenant, any subtenant or licensee and their
respective officers, employees and agents.

                              ARTICLE 8 - SECURITY


     8.01.  Tenant has deposited with Landlord the Security Deposit as security
for the full and faithful payment and performance by Tenant of Tenant's
obligations under this Lease.  If Tenant defaults in the full and prompt payment
and performance of any of its obligations under this Lease, including, without
limitation, the payment of Rent, Landlord may use, apply or retain the whole or
any part of the Security Deposit to the extent required for the payment of any
Rent or any other sums as to which Tenant is in default or for any sum which
Landlord may expend or may be required to expend by reason of Tenant's default
in respect of any of Tenant's obligations under this Lease, including, without
limitation, any damages or deficiency in the reletting of the Demised Premises,
whether such damages or deficiency accrue before or after summary proceedings or
other re-entry by Landlord.  If Landlord shall so use, apply or retain the whole
or any part of the security, Tenant shall upon demand immediately deposit with
Landlord a sum equal to the amount so used, applied and retained, as security as
aforesaid.  If Tenant shall fully and faithfully pay and perform all of Tenant's
obligations under this Lease, the Security Deposit or any balance thereof to
which Tenant is entitled shall be returned or paid over to Tenant after the date
on which this Lease shall expire or sooner end or terminate, and after delivery
to Landlord of entire possession of the Demised Premises.  In the event of any
sale or leasing of the Land, Landlord shall have the right to transfer the
security to which Tenant is entitled to the vendee or lessee and Landlord shall
thereupon be released by Tenant from all liability for the return or payment
thereof; and Tenant shall look solely to the new landlord for the return or
payment of the same; and the provisions hereof shall apply to every transfer or
assignment made of the same to a new landlord.  Tenant shall not assign or
encumber or attempt to assign or encumber the monies deposited herein as
security, and neither Landlord nor its successors or assigns shall be bound by
any such assignment, encumbrance, attempted assignment or attempted encumbrance.

     (b). In lieu of the cash security required by this Lease, Tenant shall
provide to Landlord an irrevocable Letter of Credit in the amount of the
Security Deposit in form and substance satisfactory to Landlord and issued by a
financial institution approved by Landlord  (which approval shall not be
unreasonably withheld) and otherwise conforming to Exhibit F, annexed hereto and
made a part hereof.  Landlord shall have the right, upon written notice to
Tenant (except for Tenant's non-payment of Rent or for Tenant's failure to
comply with Article 8.03 for which no notice shall be required), and regardless
of the exercise of any other remedy the

                                       15
<PAGE>

Landlord may have by reason of a default, to draw upon said Letter of Credit to
cure any default of Tenant or for any purpose authorized by section 8.01(a) of
this Lease and if Landlord does so, Tenant shall, upon demand, additionally fund
the Letter of Credit with the amount so drawn so that Landlord shall have the
full deposit on hand at all times during the Term of the Lease and for a period
of thirty (30) days' thereafter. In the event of a sale of the Building or a
lease of the Building subject to this Lease, Landlord shall have the right to
transfer the security to the vendee or lessee.

     8.02. The Letter of Credit shall expire not earlier than thirty (30) days
after the Expiration Date of this Lease.  Upon Landlord's prior consent, the
Letter of Credit may be of the type which is automatically renewed on an annual
basis (Annual Renewal Date), provided however, in such event Tenant  shall
maintain the Letter of Credit and its renewals in full force and effect during
the entire Term of this Lease (including any renewals or extensions) and for a
period of thirty (30) days thereafter. The Letter of Credit will contain a
provision requiring the issuer thereof to give the beneficiary (Landlord) sixty
(60) days' advance written notice of its intention not to renew the Letter of
Credit on the next Annual Renewal Date.

     8.03.  In the event Tenant shall fail to deliver to Landlord a substitute
irrevocable Letter of Credit, in the amount stated above, on or before thirty
(30) days prior to the next Annual Renewal Date, Landlord shall be permitted to
draw upon the Letter of Credit without further notice to Tenant.  In addition,
said failure shall be deemed a default under this Lease unless Tenant provides
such substitute irrevocable Letter of Credit within the cure period set forth in
Section 27.02(b). Any cash balance remaining after applying the amount of any
draw of such Letter of Credit, shall be held and applied as cash security under
this Article 8. In the event Tenant provides a replacement Letter of Credit
pursuant to this Article, Landlord shall return any unused cash security
remaining after such draw upon the original Letter of Credit.

     8.04. Notwithstanding anything to the contrary contained in this Article 8,
in the event that during the Term of this Lease, Tenant's tangible net worth, as
determined in accordance with generally accepted accounting principals
("Tenant's Net Worth"), is less than One Hundred Thirty Million Dollars
($130,000,000) then Tenant shall be required to increase the amount of the
Security Deposit and the Letter of Credit for such time as Tenant's Net Worth is
less than $130,000,000 (including all renewal and extensions) to an amount equal
to six (6) months' Fixed Rent then payable under this Lease. At such time as
Tenant's Net Worth is again equal or greater than $130,000,000 for two (2)
consecutive fiscal quarters, the Security Deposit and Letter of Credit shall be
reduced to an amount equal to three (3) months' Fixed Rent then payable under
this Lease. Such increase or decrease to the Letter of Credit, as the case may
be, may be by amendment or replacement with a new Letter of Credit conforming to
the requirements of this Article 8.

                           ARTICLE 9 - SUBORDINATION

                                       16
<PAGE>

     9.01. Provided that (a) a Superior Mortgagee shall execute and deliver to
Tenant an agreement, in recordable form, substantially in the form attached
hereto and made a part hereof as Exhibit H, or if required by such Mortgagee, in
such Mortgagee's substantively  equivalent standard form, to the effect that,
provided no default has occurred and is continuing beyond any applicable notice
and cure period provided in this Lease, such Superior Mortgagee will not name or
join Tenant as a party defendant or otherwise in any suit, action or proceeding
to enforce any rights granted to such Superior Mortgagee against Landlord under
its Superior Mortgage, and to the further effect that if there shall be a
foreclosure of its Superior Mortgage, that the Superior Mortgagee will not make
Tenant a party defendant to such foreclosure, evict Tenant, disturb Tenant's
possession under this Lease, or terminate or disturb Tenant's Leasehold estate
or rights, hereunder, or (b) a Superior Lessor shall execute and deliver to
Tenant an agreement, in recordable form, substantially in the form attached
hereto and made a part hereof as Exhibit I, to the effect that, provided no
default has occurred and is continuing beyond any applicable notice and cure
period provided in this Lease, such Superior Lessor will not name or join Tenant
as a party defendant or otherwise in any suit, action or proceeding to enforce
any rights granted to such Superior Lessor against Landlord under its Superior
Lease, and to the further effect that if its Superior Lease shall terminate or
be terminated for any reason, such Superior Lessor will recognize Tenant as the
direct tenant of such Superior Lessor on the same terms as are contained in this
Lease (any such agreement of similar import from a Superior Mortgagee or a
Superior Lessor, as the case may be, being hereinafter referred to as a "Non-
Disturbance Agreement"), this Lease, and all rights of Tenant hereunder, are and
shall be subject and subordinate to all ground leases and underlying leases of
the Land and/or the Building now or hereafter existing and to all Mortgages
which may now or hereafter affect the Land and/or building and/or any of such
leases, whether or not such Mortgages or leases shall also cover other lands
and/or buildings, to each and every advance made or hereafter to be made under
such Mortgages, and to all renewals, modifications, replacements and extensions
of such leases and such Mortgages and spreaders and consolidations of such
Mortgages.  The provisions of this Section 9.01 shall be self-operative and no
further instrument of subordination shall be required.  In confirmation of such
subordination, Tenant shall promptly execute, acknowledge and deliver any
instrument that Landlord, the lessor under any such lease or the Mortgagee of
any such Mortgage or any of their respective successors in interest may
reasonably request to evidence such subordination.

     9.02.  If any act or omission of Landlord would give Tenant the right,
immediately or after lapse of a period of time, to cancel or terminate this
Lease, or to claim a partial or total eviction, Tenant shall not exercise such
right (a) until it has given written notice of such act or omission to Landlord
and each Superior Mortgagee and each Superior Lessor whose name and address
shall previously have been furnished to Tenant, and (b) until a thirty (30) day
period for remedying such act or omission shall have elapsed following the
giving of such notice or such longer period as may be reasonably required if
such condition is not susceptible to remedy within such thirty (30) day period
provided such Superior Mortgagee or Superior Lessor commences and diligently
pursues such remedy (which reasonable period shall in no event be less than the
period to which Landlord would be entitled under the Lease, after similar
notice, to effect such remedy, and with respect to any Superior Lessor which is
an Affiliate of Landlord, shall not exceed the period to which Landlord would be
entitled under the Lease).

                                       17
<PAGE>

     9.03.  If any Superior Lessor or Superior Mortgagee shall succeed to the
rights of Landlord under this Lease, whether through possession or foreclosure
action or delivery of a new lease or deed, then at the request of such party so
succeeding to Landlord's rights ("Successor Landlord") and upon such Successor
Landlord's written agreement to accept Tenant's attornment, Tenant shall attorn
to and recognize such Successor Landlord as Tenant's landlord under this Lease
and shall promptly execute and deliver any instrument that such Successor
Landlord may reasonably request to evidence such attornment.  Upon such
attornment this Lease shall continue in full force and effect as a direct lease
between the Successor Landlord and Tenant upon all of the terms, conditions and
covenants as are set forth in this Lease except that the Successor Landlord
(unless such Successor Landlord is an Affiliate of Landlord) shall not (a) be
liable for any previous act or omission of Landlord under this Lease; (b) be
subject to any offset, not expressly provided for in this Lease, which
theretofore shall have accrued to Tenant against Landlord; (c) be liable for the
return of any Security Deposit, in whole or in part, to the extent that same is
not paid over to the Successor Landlord; or (d) be bound by any previous
modification of this Lease or by any previous prepayment of more than one
month's Fixed Rent or Additional Charges, unless such modification or prepayment
shall have been expressly approved in writing by the Superior Lessor of the
Superior Lease or the Mortgagee of the Superior Mortgage through or by reason of
which the Successor Landlord shall have succeeded to the rights of Landlord
under this Lease.

                          ARTICLE 10 - QUIET ENJOYMENT


     10.01.  So long as Tenant pays all of the Rent and performs all of Tenant's
other obligations hereunder, Tenant shall peaceably and quietly have, hold and
enjoy the Demised Premises without hindrance, ejection or molestation by
Landlord or any person lawfully claiming through or under Landlord, subject,
nevertheless, to the provisions of this Lease.

               ARTICLE 11 - ASSIGNMENT, SUBLETTING AND MORTGAGING


     11.01.  Tenant shall not, whether voluntarily, involuntarily, or by
operation of law or otherwise, (a) assign or otherwise transfer this Lease, (b)
sublet the Demised Premises or any part thereof, or allow the same to be used,
occupied or utilized by anyone other than Tenant (or Tenant's Affiliates, as
hereinafter provided), or (c) mortgage, pledge, encumber or otherwise
hypothecate this Lease in any manner whatsoever, without in each instance
obtaining the prior written consent of Landlord.

                                       18
<PAGE>

     Landlord agrees not to unreasonably withhold or delay its consent to the
subletting of the Demised Premises or an assignment of this Lease. Landlord
shall reply to Tenant's request for consent to assignment or subletting within
ten (10) business days after receipt of notice of such request.  In the event
Landlord denies such consent, Landlord shall, upon request of Tenant, provide
Tenant with the reasons considered by Landlord in denying such consent. In
determining reasonableness, Landlord may take into consideration all relevant
factors surrounding the proposed sublease or assignment, including, without
limitation, the following: (i) The ability and history of the proposed assignee
or subtenant complying with Legal Requirements and lease and business
obligations; (ii) the nature of the business and the proposed use of the Demised
Premises by the proposed assignee or subtenant in relation to the other tenants
or occupants of the Building or Development; (iii) whether the proposed assignee
or subtenant is then a tenant (or subsidiary, affiliate or parent of a tenant)
of other space in the Building or Development (if Landlord or its affiliates
have or anticipate having a substantially equivalent sized space for a
substantially equivalent term available); (iv) the financial condition of the
proposed assignee or subtenant; and (v) any material adverse effect that the
proposed assignee's or subtenant's occupancy or use of the Demised Premises
would have upon the operation and maintenance of the Building and the
Development.  In any event, at no time shall Tenant be permitted to have any
sublease (or further sublease) for less than one-half a floor of the Building
with respect to the portions of the Demised Premises located on the fifth and
sixth floors, or more than one subtenant with respect to the grade level space.
Notwithstanding anything to the contrary contained herein, Landlord shall not be
entitled to deny approval by reason of a leasing restriction granted to any
other tenant, other than a restriction with regard to Discover, MasterCard or
Visa.

     In the event the Demised Premises are sublet or licensed or this Lease is
assigned or otherwise transferred, Tenant shall pay to Landlord, in addition to
the Rent otherwise payable under this Lease, an Additional Charge (herein the
"Excess Amount") equal to: (i) in the case of an assignment or transfer, fifty
percent (50%) of all sums and other consideration paid to Tenant by the assignee
or transferee for or by reason of such assignment or transfer, and (ii) in the
case of a sublease or license, fifty percent (50%) of the rents, additional
charge and other consideration payable under the sublease to Tenant by the
subtenant in excess of the Fixed Rent and Additional Charges payable under this
Lease (other than the Excess Amount) during the term of the sublease in respect
of the subleased space (at the rate per square foot payable by Tenant under this
Lease). Tenant shall be entitled to a credit against the Excess Amount to be
applied against the first dollars payable on account of the Excess Amount and
continuing until the credit is fully depleted, equal to the total aggregate
actual reasonable expense incurred by Tenant in connection with such assignment
or subletting, licensing or transfer, as substantiated by Tenant, in writing, to
Landlord's reasonable satisfaction, including, without limitation, fit-up costs
and reasonable and actual subtenant lease inducement costs, a reasonable
brokerage fee and reasonable legal fees, as the case may be; provided, however,
in no event shall such credit exceed the Excess Amount paid to Landlord.

     Tenant shall not be required to obtain Landlord's consent to an assignment
or sublease to an Affiliate of Tenant, provided however that Tenant shall be
required to comply with the

                                       19
<PAGE>

notice and other provisions of this Article 11 with respect to such assignment
or sublease. The Tenant shall not be required to pay the Excess Amount with
respect to any assignment or sublease to an Affiliate of Tenant. Notwithstanding
anything contained herein to the contrary Tenant shall not form or sublet,
assign or transfer to a Tenant Affiliate for the principal or primary purpose of
evading the Excess Amount payments otherwise required hereunder, or the
restrictions on subletting, assignment or transfer otherwise provided in this
Lease; in the event of any such transfer Tenant shall be required to comply with
Excess Amount provisions and the restrictions on subletting, assignment and
transfer otherwise provided in this Article 11 (including, but not limited to
Landlord's recapture rights pursuant to section 11.08) as if such subtenant,
assignee or transferee were not an Affiliate of Tenant. Landlord acknowledges
that Tenant's Affiliate, Triac Services Corp., a New York corporation, doing
business as National Discount Brokers, shall be permitted to occupy the Demised
Premises pursuant to a sublease or other occupancy agreement between Tenant and
such Tenant Affiliate.

     If Landlord fails to respond to a request for consent made by Tenant
pursuant to this Section 11.01 within ten (10) Business Days of receipt thereof,
Landlord shall be deemed to have given consent as to such request.

     11.02.  If at any time (a) the original Tenant named herein, (b) the then
Tenant, (c) any Guarantor, or (d) any Person owning a majority of the voting
stock of, or directly or indirectly controlling, the then Tenant shall be a
corporation or partnership, any transfer of voting stock or partnership interest
resulting in the person(s) who shall have owned a majority of such corporation's
shares of voting stock or the general partners' interest in such partnership, or
member's interest in any limited liability company or similar entity, as the
case may be, immediately before such transfer, ceasing to own a majority of such
shares of voting stock or general partner's interest, or member's interest, as
the case may be, except as the result of transfers by inheritance, or transfers
to an Affiliate of Tenant as provided in this Section 11.02 shall be deemed to
be an assignment of this Lease as to which Landlord's consent shall have been
required, and in any such event Tenant shall notify Landlord.  The provisions of
this Section 11.02 shall not be applicable to any corporation all the
outstanding voting stock of which is listed on a national securities exchange
(as defined in the Securities Exchange Act of 1934, as amended) or is traded in
the over-the-counter market with quotations reported by the National Association
of Securities Dealers through its automated system for reporting quotations and
shall not apply to, and Landlord's consent shall not be required for,
transactions with a corporation or other entity (w) into or with which the then
Tenant is merged or consolidated, or (x) to which substantially all of the then
Tenant's assets are transferred, or (y) to any corporation or other entity which
controls or is controlled by the then Tenant or is under common control with the
then Tenant, provided that in any of such events (i) the successor to Tenant has
a net worth computed in accordance with generally accepted accounting principles
at least equal to the greater of (1) the net worth of Tenant immediately prior
to such merger, consolidation or transfer, or (2) the net worth of the original
Tenant on the date of this Lease, and (ii) proof satisfactory to Landlord of
such net worth shall have been delivered to Landlord at least 10 days prior to
the effective date of any such transaction.  For the purposes of this Section,
the words "voting stock" shall refer to shares of stock regularly entitled to
vote for the election of directors of the corporation.  Landlord

                                       20
<PAGE>

shall have the right at any time and from time to time during the Term to
inspect the stock record books of the corporation to which the provisions of
this Section 11.02 apply, and Tenant will produce the same on request of
Landlord.

     11.03  If this Lease is assigned, whether or not in violation of this
Lease, Landlord may collect rent from the assignee.  If the Demised Premises or
any part thereof are sublet or used or occupied by anybody other than Tenant,
whether or not in violation of this Lease, Landlord may, after default by
Tenant, and expiration of Tenant's time to cure such default, collect rent from
the subtenant or occupant.  In either event, Landlord may apply the net amount
collected to the Rent, but no such assignment, subletting, occupancy or
collection shall be deemed a waiver of any of the provisions of Section 11.01 or
Section 11.02, or the acceptance of the assignee, subtenant or occupant as
tenant, or a release of Tenant from the performance by Tenant of Tenant's
obligations under this Lease.  The consent by Landlord to any assignment,
mortgaging, subletting or use or occupancy by others shall not in any way be
considered to relieve Tenant from obtaining the express written consent of
Landlord to any other or further assignment, mortgaging or subletting or use or
occupancy by others not expressly permitted by this Article 11.  References in
this Lease to use or occupancy by others (that is, anyone other than Tenant)
shall not be construed as limited to subtenants and those claiming under or
through subtenants but shall be construed as including also licensees and others
claiming under or through Tenant, immediately or remotely.

     11.04.  Any permitted assignment or transfer, whether made with Landlord's
consent pursuant to Section 11.01 or without Landlord's consent if permitted by
Section 11.02, shall be made only if, and shall not be effective until, the
assignee shall execute, acknowledge and deliver to Landlord an agreement in form
and substance satisfactory to Landlord whereby the assignee shall assume
Tenant's obligations under this Lease and whereby the assignee shall agree that
all of the provisions in this Article 11 shall, notwithstanding such assignment
or transfer, continue to be binding upon it in respect to all future assignments
and transfers.  Notwithstanding any assignment or transfer, whether or not in
violation of the provisions of this Lease, and notwithstanding the acceptance of
Rent by Landlord from an assignee, transferee, or any other party, the original
Tenant and any other person)s) who at any time was or were Tenant shall remain
fully liable for the payment of the Rent and for Tenant's other obligations
under this Lease.

     11.05.  The liability of the original named Tenant and any other Person(s)
(including but not limited to any Guarantor) who at any time are or become
responsible for Tenant's obligations under this Lease shall not be discharged,
released or impaired by any agreement extending the time of, or modifying any of
the terms or obligations under this Lease, or by any waiver or failure of
Landlord to enforce, any of this Lease.

     11.06.  The listing of any name other than that of Tenant, whether on the
doors of the Demised Premises or the Building directory, or otherwise, shall not
operate to vest any right or interest in this Lease or in the Demised Premises,
nor shall it be deemed to be the consent of Landlord to any assignment or
transfer of this Lease or to any sublease of the Demised Premises or to the use
or occupancy thereof by others.  Notwithstanding anything contained in this
Lease to the contrary, Landlord shall have the absolute right to withhold its
consent to an assignment

                                       21
<PAGE>

or subletting to a Person who is otherwise a tenant or occupant of the Building,
or of a building in the Development owned or managed by Landlord or its
affiliated entities in the event Landlord or its affiliates have or anticipate
having a substantially equivalent sized space for a substantially equivalent
term available.

     11.07.  Without limiting any of the provisions of Article 27, if pursuant
to the Federal Bankruptcy Code (or any similar law hereafter enacted having the
same general purpose), Tenant is permitted to assign this Lease notwithstanding
the restrictions contained in this Lease, adequate assurance of future
performance by an assignee expressly permitted under such Code shall be deemed
to mean the deposit of cash security in an amount equal to the sum of one (1)
year's Fixed Rent plus an amount equal to the Additional Charges for the
Calendar Year preceding the year in which such assignment is intended to become
effective, which deposit shall be held by Landlord for the balance of the Term,
without interest, as security for the full performance of all of Tenant's
obligations under this Lease, to be held and applied in the manner specified for
security in Section 8.01.

     11.08.  If Tenant shall propose to assign or in any manner transfer this
Lease or any interest therein, or sublet the Demised Premises or any part or
parts thereof, or grant any concession or license or otherwise permit occupancy
of all or any part of the Demised Premises by any person, Tenant shall give
notice thereof to Landlord, together with a copy of the proposed instrument that
is to accomplish same and such financial and other information pertaining to the
proposed assignee, transferee, subtenant, concessionaire or licensee as Landlord
shall require. Except with respect to an assignment or sublease to an Affiliate
of Tenant, or a merger or consolidation or transfer of substantially all of the
assets of Tenant as permitted pursuant to Section 11.02, if Tenant proposes to
assign this Lease or to sublet more than fifty percent (50%) of the Floor Space
of the Demised Premises in the aggregate and/or if either (x) such sublease or
assignment is for a term of more than five (5) years, or (y) upon the scheduled
expiration of such sublease or assignment there would then be remaining less
than two (2) years of the Term hereunder.  Landlord may, in addition to
Landlord's right to give or withhold consent, terminate this Lease with respect
to the Demised Premises in the event of an assignment, or such portion thereof
as is sublet or licensed in the event of a sublease or license, by notice given
to Tenant within thirty (30) days after receipt of said proposed instrument and
financial and other information, and upon the date specified in such notice,
which date shall be not less than 30 days and not more than 60 days after the
giving of said notice, this Lease shall terminate in case of assignment or, in
case of a sublet or license, the portion of the Demised Premises proposed to be
sublet shall be excluded from this Lease and the Floor Space of the Demised
Premises shall be reduced to reflect such exclusion.  If Landlord does not so
terminate this Lease, and (if Landlord consents to the subject transaction or if
Landlord's consent is not required to same) if Tenant does not consummate the
subject transaction within 60 days after the last day on which Landlord might
have so terminated this Lease as a result of such transaction, Tenant shall
again be required to comply with the provisions of this Section 11.08 in
connection with any such transaction as if the notice by Tenant referred to
above in this Section 11.08 had not been given.  Notwithstanding anything
contained in this Lease to the contrary, Landlord shall not be obligated to
entertain or consider any request by Tenant to consent to any proposed
assignment of this Lease or sublet of

                                       22
<PAGE>

all or any part of the Demised Premises unless each request by Tenant is
accompanied by a non-refundable fee payable to Landlord in the amount of One
Thousand Dollars ($1,000.00) to cover Landlord's administrative, legal, and
other costs and expenses incurred in processing each of Tenant's requests.
Neither Tenant's payment nor Landlord's acceptance of the foregoing fee shall be
construed to impose any obligation whatsoever upon Landlord to consent to
Tenant's request.

                       ARTICLE 12 - COMPLIANCE WITH LAWS


     12.01.  Tenant shall comply with all Legal Requirements which shall, in
respect of the Tenant's particular use of the Demised Premises, or the abatement
of any nuisance in, on or about the Demised Premises, Tenant's Work or Tenant's
installations, impose any violation, order or duty on Landlord or Tenant; and
Tenant shall pay all the costs, expenses, fines, penalties and damages which may
be imposed upon Landlord or any Superior Lessor by reason of or arising out of
Tenant's failure to fully and promptly comply with and observe the provisions of
this Section 12.01.  However, Tenant need not comply with any such law or
requirement of any public authority so long as Tenant shall be contesting the
validity thereof, or the applicability thereof to the Demised Premises, in
accordance with Section 12.02. The cost of compliance by Landlord with any Legal
Requirements with respect to the Building which are not attributable to Tenant,
its business, Tenant's Work or Tenant's installations, or the Tenant's
particular use of the Demised Premises, shall be performed by Landlord and shall
be included in Operating Expenses, subject to the provisions of Section R5 of
the Rider.

     12.02.  Tenant may contest, by appropriate proceedings prosecuted
diligently and in good faith, the validity, or applicability to the Demised
Premises, of any Legal Requirement, provided that (a) Landlord shall not be
subject to criminal penalty or to prosecution for a crime, and neither the
Demised Premises nor any part thereof shall be subject to being condemned or
vacated, by reason of non-compliance or otherwise by reason of such contest; (b)
before the commencement of such contest, Tenant shall furnish to Landlord either
(i) the bond of a surety company satisfactory to Landlord, which bond shall be,
as to its provisions and form, satisfactory to Landlord, and shall be in an
amount at least equal to 125% of the cost of such compliance (as estimated by a
reputable contractor designated by Landlord) and shall indemnify Landlord
against the cost thereof and against all liability for damages, interest,
penalties and expenses (including reasonable attorneys' fees and expenses),
resulting from or incurred in connection with such contest or non-compliance, or
(ii) other security in place of such bond satisfactory to Landlord;  (c) such
non-compliance or contest shall not constitute or result in any violation of any
Superior Lease or Superior Mortgage, or if any such Superior Lease and/or
Superior Mortgage shall permit such non-compliance or contest on condition of
the taking of action or furnishing of security by Landlord, such action shall be
taken and such security shall be furnished at the expense of Tenant; and (d)
Tenant shall keep Landlord advised as to the status of such  proceedings.
Without limiting the application of the above, Landlord shall be deemed subject
to prosecution for a crime if Landlord, or its  managing agent, or any officer,
director, partner, shareholder or employee of Landlord or its managing agent, as
an individual, is charged with a crime of any kind or degree whatsoever, whether
by service of a summons or otherwise, unless such charge is withdrawn

                                       23
<PAGE>

before Landlord or its managing agent, or such officer, director, partner,
shareholder or employee of Landlord or its managing agent (as the case may be)
is required to plead or answer thereto. Notwithstanding anything contained in
this Lease to the contrary, Tenant shall not file any Real Estate Tax Appeal
with respect to the Land, Building or the Demised Premises.

                      ARTICLE 13 - INSURANCE AND INDEMNITY


     13.01.  Landlord shall maintain or cause to be maintained All Risk
insurance in respect of the Building and other improvements on the Land normally
covered by such insurance (except for the property Tenant is required to cover
with insurance under Section 13.02 and similar property of other tenants and
occupants of the Building or buildings and other improvements which are on land
neither owned by nor leased to Landlord) for the benefit of Landlord, any
Superior Lessors, any Superior Mortgagees and any other parties Landlord may at
any time and from time to time designate, as their interests may appear, but not
for the benefit of Tenant, and shall maintain rent insurance as required by any
Superior Lessor or any Superior Mortgagee.  The All Risk insurance will be in
the amounts required by any Superior Lessor or any Superior Mortgagee but not
less than the replacement cost of the Building (exclusive of footings and
foundations). Landlord may also maintain any other forms and types of insurance
as Landlord may reasonably determine in respect of the Building and Land.
Landlord shall have the right to provide any insurance maintained or caused to
be maintained by it under blanket policies.

     13.02.  Tenant shall maintain the following insurance:  (a) comprehensive
general public liability insurance in respect of the Demised Premises and the
conduct and operation of business therein, having not less than a $5,000,000.00
combined single limit per occurrence for bodily injury or death to any one
person and for bodily injury or death to any number of persons in any one
occurrence, and for property damage, including water damage and sprinkler
leakage legal liability (coverage to include but not be limited to (i) premises
operation, completed operations, broad form contractual liability and product
liability, (ii) comprehensive automobile, truck and vehicle liability insurance
covering all owned, hired and non-owned vehicles used by the contractor(s) in
connection with their work and any loading of such vehicles, with limits as
stated above and (iii) worker's compensation, employers liability and
occupational disease insurance as required by statutes, but in any event not
less than $500,000.00 for Coverage B covering all damages and injuries arising
from each accident or occupational disease); and  (b) All Risk insurance in
respect of Tenant's stock in trade, fixtures, furniture, furnishings, removable
floor coverings, equipment, signs and all other property of Tenant in the
Demised Premises in any amounts required by any Superior Lessor or any Superior
Mortgagee but not less than the replacement cost of the property covered and not
more than the amount sufficient to avoid the effect of the co-insurance
provisions of the applicable policy or policies, and (c) such other insurance as
is commonly required by landlords of tenants for the benefit of landlords in
buildings of similar character, quality and location. Landlord may at any time
and from time to time, but not more frequently than once every five (5) years
during the Term) require that the limits for the comprehensive general public
liability insurance to be maintained by Tenant be increased to the limits that
new tenants in the Building are required by Landlord to maintain.  Tenant shall
deliver

                                       24
<PAGE>

to Landlord and any additional named insured(s) certificates for such fully
paid-for policies upon execution hereof. Tenant shall procure and pay for
renewals of such insurance from time to time before the expiration thereof, and
Tenant shall deliver to Landlord and any additional insured(s) certificates
therefor at least thirty (30) days before the expiration of any existing policy.
All such policies shall be issued by companies of recognized responsibility,
having a Bests Key Rating Guide of not less than A, Class VII, licensed to do
business in New Jersey, and all such policies shall contain a provision whereby
the same cannot be canceled unless Landlord and any additional insured(s) are
given at least thirty (30) days' prior written notice of such cancellation. The
certificates of insurance to be delivered to Landlord by Tenant shall (with
respect to policies under a(i), a(ii) and, where applicable,(c)) name Landlord
as an additional insured and, at Landlord's request, shall also name any
Superior Lessors or Superior Mortgagees as additional insureds, and the
following phrase must be typed on the certificate of insurance: "Hartz Mountain
Industries, Inc., and its respective subsidiaries, affiliates, associates, joint
ventures, and partnerships, are hereby named as additional insureds as their
interests may appear (and if Landlord has so requested, Tenant shall include any
Superior Lessors and Superior Mortgagees as additional insured(s)). It is
intended for this insurance to be primary and non-contributing." Tenant shall
give Landlord at least thirty (30) days' prior written notice that any such
policy is being canceled or replaced. Any dispute regarding the coverages to be
required under subsection (c) of this Section 13.02 may be submitted to
arbitration in accordance with Article 36 of this Lease.

     13.03.  Tenant shall not do, permit or suffer to be done any act, matter,
thing or failure to act in respect of the Demised Premises or use or occupy the
Demised Premises or conduct or operate Tenant's business in any manner
objectionable to any insurance company or companies whereby the fire insurance
or any other insurance then in effect in respect of the Land and Building or any
part thereof shall become void or suspended or whereby any premiums in respect
of insurance maintained by Landlord shall be higher than those which would
normally have been in effect for the occupancy contemplated under the Permitted
Uses.  In case of a breach of the provisions of this Section 13.03, in addition
to all other rights and remedies of Landlord hereunder, Tenant shall (a)
indemnify Landlord and the Superior Lessors and hold Landlord and the Superior
Lessors harmless from and against any loss which would have been covered by
insurance which shall have become void or suspended because of such breach by
Tenant and (b) pay to Landlord any and all increases of premiums on any
insurance, including, without limitation, rent insurance, resulting from any
such breach.

     13.04  (a).  Tenant shall indemnify and hold harmless Landlord and all
Superior Lessors and its and their respective partners, joint venturers,
directors, officers, agents, servants and employees from and against any and all
claims arising from or in connection with (a) the conduct or management of the
Demised Premises or of any business therein, or any work or thing whatsoever
done, or any condition created (other than by Landlord) in the Demised Premises
during the Term or during the period of time, if any, prior to the Commencement
Date that Tenant may have been given access to the Demised Premises; (b) any
act, omission or negligence of Tenant or any of its subtenants or licensees or
its or their partners, joint venturers, directors, officers, agents, employees
or contractors; and (c) any accident, injury or damage whatever

                                       25
<PAGE>

(unless caused solely by Landlord's negligence) occurring in the Demised
Premises; together with all costs, expenses and liabilities incurred in or in
connection with each such claim or action or proceeding brought thereon,
including, without limitation, all attorneys' fees and expenses. In case any
action or proceeding is brought against Landlord and/or any Superior Lessor
and/or its or their partners, joint venturers, directors, officers, agents
and/or employees by reason of any such claim, Tenant, upon notice from Landlord
or such Superior Lessor, shall resist and defend such action or proceeding by
counsel reasonably satisfactory to Landlord.

     (b).  Landlord shall indemnify and hold harmless Tenant and its partners,
directors, officers, agents, servants and employees from and against any and all
claims arising from any tortious act or omission of Landlord, or negligence of
Landlord or its agents or partners, joint ventures, directors, officers, or
employees in the conduct or management of the Common Areas; together with all
costs, expenses and liabilities incurred in or in connection with each such
claim or action or proceeding brought thereon, including , without limitation,
reasonable attorneys' fees and expenses.  In the event any action or proceeding
is brought against Tenant and/or its directors, officers, agents and/or
employees by reason of any such claim, Landlord, upon notice from Tenant, shall
resist and defend such action or proceeding by counsel reasonably satisfactory
to Tenant. Counsel satisfactory to Landlord's insurance carrier shall be deemed
satisfactory to Tenant for purposes of this paragraph.

     13.05 (a).  Neither Landlord nor any Superior Lessor shall be liable or
responsible for, and Tenant hereby releases Landlord and each Superior Lessor
from, all liability and responsibility to Tenant and any person claiming by,
through or under Tenant, by way of subrogation or otherwise, for any injury,
loss or damage to any person or property in or around the Demised Premises or to
Tenant's business irrespective of the cause of such injury, loss or damage, and
Tenant shall require its insurers to include in all of Tenant's insurance
policies which could give rise to a right of subrogation against Landlord or any
Superior Lessor a clause or endorsement whereby the insurer waives any rights of
subrogation against Landlord and such Superior Lessors or permits the insured,
prior to any loss, to agree with a third party to waive any claim it may have
against said third party without invalidating the coverage under the insurance
policy.

     (b).  Tenant shall not be liable or responsible for, and Landlord hereby
releases Tenant from, all liability and responsibility to Landlord and any
person claiming by, through or under Landlord, by way of subrogation or
otherwise, for any injury, loss or damage to any person or property in or around
the Building or Land to Landlord's business irrespective of the cause of such
injury, loss or damage, and Landlord shall require its insurers to include in
all of Landlord's insurance policies which could give rise to a right of
subrogation against Tenant a clause or endorsement whereby the insurer waives
any rights of subrogation against or permits the insured, prior to any loss, to
agree with a third party to waive any claim it may have against said third party
without invalidating the coverage under the insurance policy.

                       ARTICLE 14 - RULES AND REGULATIONS

                                       26
<PAGE>

     14.01.  Tenant and its employees and agents shall faithfully observe and
comply with the Rules and Regulations and such reasonable changes therein
(whether by modification, elimination or addition) as Landlord at any time or
times hereafter may make and communicate to Tenant, which in Landlord's
judgment, shall be necessary for the reputation, safety, care or appearance of
the Land and Building, or the preservation of good order therein, or the
operation or maintenance of the Building or its equipment and fixtures, or the
Common Areas; provided, however, that in case of any conflict or inconsistency
between the provisions of this Lease and any of the Rules and Regulations, the
provisions of this Lease shall control.  Nothing in this Lease contained shall
be construed to impose upon Landlord any duty or obligation to enforce the Rules
and Regulations against any other tenant or any employees or agents of any other
tenant, and Landlord shall not be liable to Tenant for violation of the Rules
and Regulations by any other tenant or its employees, agents, invitees or
licensees. Landlord shall not discriminatorily enforce any Rule or Regulation
against Tenant which Landlord is not enforcing, to the extent applicable,
against the other tenants in the Building.

                            ARTICLE 15 - ALTERATIONS


     15.01 Tenant shall not make any structural alterations or additions to the
Demised Premises, or make any holes or cuts in the walls, ceilings, roofs, or
floors thereof, or change the exterior color or architectural treatment of the
Demised Premises, or make any non-structural alterations costing One Hundred
Thousand Dollars ($100,000.00) or more (exclusive of the cost of carpeting or
decoration) in the aggregate with respect to each project (herein referred to as
the "Threshold Amount"), without on each occasion first obtaining the consent of
Landlord, which consent with respect to non-structural alterations shall not be
unreasonably withheld or delayed or conditioned.  Landlord's consent shall not
be required for proposed non-structural alterations costing, in the aggregate
per project, less than the Threshold Amount; provided however that in all events
Tenant shall submit to Landlord plans and specifications for such work at the
time Landlord's consent is sought, or if no consent is required, prior to
commencement of such proposed alterations.  Tenant shall pay to Landlord upon
demand the actual cost and expense of Landlord in (a) reviewing said plans and
specifications and (b) inspecting the alterations to determine whether the same
are being performed in accordance with the approved plans and specifications and
all Legal Requirements and Insurance Requirements, including, without
limitation, the fees of any architect or engineer employed by Landlord for such
purpose (any dispute as to such cost may be submitted to arbitration in
accordance with Article 36). Before proceeding with any permitted alteration
project which will cost more than the Threshold Amount, as estimated by a
reputable contractor designated by Landlord, Tenant shall obtain and deliver to
Landlord either (i) a performance bond and a labor and materials payment bond
(issued by a corporate surety licensed to do business in New Jersey), each in an
amount equal to 125% of such estimated cost and in form satisfactory to
Landlord, or (ii) such other security as shall be satisfactory to Landlord.
Tenant shall fully and promptly comply with and observe the Rules and
Regulations then in force in respect of the making of alterations.  The
Threshold Amount shall be increased by $50,000 on the tenth anniversary of the
Rent Commencement Date and on each tenth anniversary thereafter during the Term
(as extended by the exercise of any renewal options

                                       27
<PAGE>

by Tenant hereunder). Any review or approval by Landlord of any plans and/or
specifications with respect to any alterations is solely for Landlord's benefit,
and without any representation or warranty whatsoever to Tenant in respect of
the adequacy, correctness or efficiency thereof or otherwise. At the time
Landlord replies to Tenant's request for consent to an alteration, or if no
consent is required, within ten (10) business days after Tenant notifies
Landlord of a proposed alteration, Landlord will notify Tenant whether or not
such alteration must be removed and the Demised Premises restored at the end of
the Term.


     15.02.  Tenant shall obtain all necessary governmental permits and
certificates for the commencement and prosecution of permitted alterations and
for final approval thereof upon completion, and shall cause alterations to be
performed in compliance therewith and with all applicable Legal Requirements and
Insurance Requirements.  Alterations shall be diligently performed in a good and
workmanlike manner, using new materials and equipment at least equal in quality
and class to the better of (a) the original installations of the Building, or
(b) the then standards for the Building reasonably established by Landlord.
Alterations shall be performed by contractors first approved by Landlord;
provided, however, that any alterations in or to the mechanical, electrical,
sanitary, heating, ventilating, air conditioning or other systems of the
Building shall be performed either by the contractor(s) designated by Landlord
or by Tenant's contractor(s) jointly in consultation with the contractor(s)
designated by Landlord.  Alterations shall be made in such manner as not to
unreasonably interfere with or delay and as not to impose any additional expense
upon Landlord in the construction, maintenance, repair or operation of the
Building; and if any such additional expense shall be incurred by Landlord as a
result of Tenant's making of any alterations, Tenant shall pay any such
additional expense upon demand.  Throughout the making of alterations, Tenant
shall carry, or cause to be carried, worker's compensation insurance in
statutory limits and general liability insurance, with completed operation
endorsement, for any occurrence in or about the Building, under which Landlord
and its managing agent and any Superior Lessor whose name and address shall
previously have been furnished to Tenant shall be named as parties insured, in
such limits as Landlord may reasonably require, with insurers reasonably
satisfactory to Landlord.  Tenant shall furnish Landlord with reasonably
satisfactory evidence that such insurance is in effect at or before the
commencement of alterations and, on request, at reasonable intervals thereafter
during the making of alterations.

     15.03.  In performing Tenant's Work or any alterations pursuant to this
Lease Tenant shall be permitted to utilize a general contractor or construction
manager of Tenant's choosing, subject to Landlord's approval which shall not be
unreasonably withheld or delayed. Landlord shall not charge Tenant a
construction supervisory fee for any Tenant's Work or alterations performed by
Tenant's general contractor, or Tenant's construction manager.  In the event
Landlord provides Tenant with temporary power, HVAC, elevator, or hoist use
during such work, the charges by Landlord to Tenant for such services shall be
limited to Landlord's cost, except as provided in Section R12 of the Rider.

                 ARTICLE 16 - LANDLORD'S AND TENANT'S PROPERTY


     16.01  All fixtures, equipment, improvements and appurtenances attached to
or built into the Demised Premises at the commencement of or during the Term,
whether or not by or at the expense of Tenant, shall be and remain a part of the
Demised Premises, shall be deemed to be the property of Landlord and shall not
be removed by Tenant, except as provided in Section 16.02.  Further, any
carpeting or other personal property in the Demised Premises on the Commencement
Date, unless installed and paid for by Tenant, shall be and shall remain
Landlord's property and shall not be removed by Tenant.

     16.02.  All movable partitions, business and trade fixtures, machinery and
equipment, communications equipment and office equipment, whether or not
attached to or built into the Demised Premises, which are installed in the
Demised Premises by or for the account of Tenant without expense to Landlord and
can be removed without structural damage to the Building and all furniture,
furnishings, and other movable personal property owned by Tenant and located in
the Demised Premises (collectively, "Tenant's Property") shall be and shall
remain the property of Tenant and may be removed by Tenant at any time during
the Term; provided that if any of the Tenant's Property is removed, Tenant shall
repair or pay the cost of repairing any damage to the Demised Premises, the
Building or the Common Areas resulting from the installation and/or removal
thereof.

     16.03.  At or before the Expiration Date or the date of any earlier
termination of this Lease, or within fifteen (15) days after such an earlier
termination date, Tenant shall remove from the Demised Premises all of the
Tenant's Property (except such items thereof as Landlord shall have expressly
permitted to remain, which property shall become the property of Landlord if not
removed), and Tenant shall repair any damage to the Demised Premises, the
Building and the Common Areas resulting from any installation and/or removal of
the Tenant's Property. Any items of the Tenant's Property which shall remain in
the Demised Premises after the Expiration Date or after a period of fifteen (15)
days following an earlier termination date, may, at the option of Landlord, be
deemed to have been abandoned, and in such case such items may be retained by
Landlord as its property or disposed of by Landlord, without accountability, in
such manner as Landlord shall reasonably determine at Tenant's Expense.

                      ARTICLE 17 - REPAIRS AND MAINTENANCE


     17.01.  Tenant shall, throughout the Term, take good care of the Demised
Premises, the fixtures and appurtenances therein.  Tenant shall be responsible
for all repairs, interior and exterior, structural and nonstructural, ordinary
and extraordinary, in and to the Demised Premises, and the Building (including
the facilities and systems thereof) and the Common Areas the need for which
arises out of (a) the performance or existence of the Tenant's Work or
alterations, (b) the installation, use or operation of the Tenant's Property in
the Demised Premises, (c) the moving of the Tenant's Property in or out of the
Building, or (d) the wrongful act or omission, or the misuse or neglect of
Tenant or any of its subtenants or its or their employees, agents, contractors

                                       29

or invitees.  Tenant shall promptly replace all scratched, damaged or broken
doors and glass in and about the Demised Premises and shall be responsible for
all repairs, maintenance and replacement of wall and floor coverings in the
Demised Premises and for the repair and maintenance of all sanitary and
electrical fixtures and equipment therein.  Tenant shall promptly make all
repairs in or to the Demised Premises for which Tenant is responsible, and any
repairs required to be made by Tenant to the mechanical, electrical, sanitary,
heating, ventilating, air-conditioning or other systems of the Building shall be
performed only by contractor(s) designated by Landlord.  Any other repairs in or
to the Building and the facilities and systems thereof for which Tenant is
responsible shall be performed by Landlord at Tenant's expense; but Landlord
may, at its option, before commencing any such work or at any time thereafter,
require Tenant to furnish to Landlord such security, in form (including, without
limitation, a bond issued by a corporate surety licensed to do business in New
Jersey) and amount, as Landlord shall reasonably deem necessary to assure the
payment for such work by Tenant.  Tenant shall not permit or suffer the
overloading of the floors of the Demised Premises beyond 100 pounds per square
foot live load.

     17.02.  Landlord shall be responsible for all repairs and maintenance in
and to the Building (including the facilities and systems thereof), except for
those repairs and maintenance for which Tenant is responsible pursuant to any of
the provisions of this Lease.

     17.03.  Except as otherwise expressly provided in this Lease, Landlord
shall have no liability to Tenant, nor shall Tenant's covenants and obligations
under this Lease be reduced or abated in any manner whatsoever, by reason of any
inconvenience, annoyance, interruption or injury to business arising from
Landlord's doing any repairs, maintenance, or changes which Landlord is required
or permitted by this Lease, or required by Law, to make in or to any portion of
the Building.  Landlord shall perform all repairs, maintenance or changes
diligently, with as little interference as practicable to Tenant's access to and
occupancy and use of the Building and Demised Premises. Nothing contained herein
shall be construed, however, as requiring Landlord to perform such work at times
other than Monday through Friday Business Days and during Business Hours, except
in cases of emergency. In the event that any such work or repairs shall require
Tenant to either: switch to backup power, or vacate the Demised Premises,
Landlord shall, except in cases of emergency where such notice is not
practicable, provide Tenant with not less than twenty-five (25) days prior
notice of such work or repair to permit Tenant to coordinate utilization of its
backup equipment and facilities, if required.

                          ARTICLE 18 - ELECTRIC ENERGY


     18.01. Tenant shall purchase the electric energy required by it in the
Demised Premises at its own expense on a direct-metered basis from the public
utility servicing the Building, and Landlord shall permit the risers, conduits
and feeders in the Building, to the extent available, suitable and safely
capable, to be used for the purpose of transmitting such electric energy to the
Demised Premises.  Landlord shall not be liable for any failure, inadequacy or
defect in the character or supply of electric current furnished to the Demised
Premises.

     18.02.  Tenant's use of electric energy in the Demised Premises shall not
at any time exceed the capacity of any of the electrical conductors and
equipment in or otherwise serving the Demised Premises.  In order to insure that
such capacity is not exceeded and to avert possible adverse effect upon the
Building's electric service, if and when Tenant's cumulative maximum peak demand
exceeds the amount stipulated in Exhibit C, then Tenant shall not, except as
contemplated by Exhibit C, without Landlord's prior consent in each instance
(which shall not be unreasonably withheld or delayed), connect any fixtures,
appliances or equipment to the Building's electric distribution system or make
any alteration or addition to the electric system of the Demised Premises
existing on the Tenant Possession Date.  Should Landlord grant such consent, all
additional risers or other equipment required therefor shall be provided by
Landlord and the cost thereof shall be paid by Tenant to Landlord on demand.

              ARTICLE 19 - HEAT, VENTILATION AND AIR-CONDITIONING


     19.01.   So long as Tenant is not in default under this Lease beyond any
applicable notice or cure periods, Landlord shall maintain and operate the
heating, ventilating and air-conditioning systems installed by Landlord as part
of Landlord's Work ("HVAC") serving the Demised Premises, and shall furnish HVAC
in the Demised Premises as may be reasonably required (except as otherwise
provided in this Lease and except for any special requirements of Tenant arising
from its particular use of the Demised Premises) for reasonably comfortable
occupancy of the Demised Premises, during Business Hours on Business Days within
the limits prescribed by the Legal Requirements and as specified in Exhibit C.
If Tenant shall require HVAC at any other time, Landlord agrees that access to
such service will be provided to Tenant through use of a key switch or remote or
telephone access to computerized building system (with each floor above grade
consisting of two (2) zones of approximately one-half ( 1/2) floor, with the
grade level portion of the Demised Premises space consisting of one zone and the
sixth floor portion of the Demised Premises consisting of one zone), and Tenant
shall pay to Landlord, within thirty (30) days of invoice or demand, an
Additional Charge for such service at the rate of Thirty-seven and 50/100
Dollars ($37.50) per hour, per zone of the Demised Premises for such services;
Landlord shall also make available to Tenant supplemental condenser water
capacity to provide up to 100 tons of supplemental cooling 24 hours per day, 365
days per year at the initial rate of Six & 00/100 ($6.00) Dollars per hour
utilized (such rates for HVAC and supplemental condenser water being referred to
herein as

                                       31
<PAGE>

the "HVAC Rates"). The HVAC Rates shall be subject to increase (but not
decrease) upon each anniversary of the Rent Commencement Date, by the greater of
(a) the percentage increase (but not decrease) in the CPI in effect on such
anniversary over the CPI in effect on date which is twelve months prior to the
date for which such increase is being calculated, or (b) the percentage increase
(but not decrease) in the utility rates in effect with respect to the Building
in effect on such anniversary over the utility rates in effect with respect to
the Building on date which is twelve months prior to the date for which such
increase is being calculated.

     19.02.  The performance by Landlord of its obligation under Section 19.01
in respect of HVAC is conditioned on the connected electric load within the
Demised Premises not exceeding the specifications set forth in Exhibit C. Use of
the Demised Premises, or any part thereof, in a manner exceeding the HVAC design
conditions (including occupancy and connected electrical load), or rearrangement
of partitioning which interferes with normal operation of the HVAC in the
Demised Premises, or the use of computer or data processing machines or other
machines or equipment, may require changes in the HVAC systems servicing the
Demised Premises, in order to provide comfortable occupancy.  Such changes, so
occasioned, shall be made by Tenant, at its expense, as alterations in
accordance with the provisions of Article 15, but only to the extent permitted
and upon the conditions set forth in Article 15.

               ARTICLE 20 - OTHER SERVICES; SERVICE INTERRUPTION


     20.01. Landlord shall provide elevator service to the Demised Premises
during Business Hours on Business Days, and Landlord shall have at least one (1)
elevator subject to call at all other times.  The use of the elevators shall be
subject to the Rules and Regulations.

     20.02.  So long as Tenant is not in default under this Lease beyond any
applicable notice or cure period, Landlord shall cause the Demised Premises,
including the exterior and the interior of the windows thereof, to be cleaned in
a manner standard to the Building and in accordance with the standards set forth
in Exhibit E.  Tenant shall pay to Landlord on demand the costs incurred by
Landlord for (a) extra cleaning work in the Demised Premises required because of
(i) wrongful acts or omissions or the misuse or neglect on the part of Tenant or
its subtenants or its or their employees or visitors, (ii) use of portions of
the Demised Premises for preparation, serving, consumption of food or beverages,
training rooms, data processing or reproducing operations, private lavatories or
toilets or other special purposes requiring greater or more difficult cleaning
work than office areas, (iii) interior glass partitions or unusual quantity of
interior glass surfaces, and (iv) non-building standard materials or finishes
installed by Tenant or at its request, and (b) removal from the Demised Premises
and the Building of any refuse and rubbish of Tenant in excess of that
ordinarily accumulated in business office occupancy or at times other than
Landlord's standard cleaning times, and (c) the use of the Demised Premises by
Tenant other than during Business Hours on Business Days.

     20.03.  Landlord, its cleaning contractor and their employees shall have
access to the

                                       32
<PAGE>

Demised Premises after 6:00 P.M. and before 11:00 P.M. and shall have the right
to use, without charge therefor, all light, power and water in the Demised
Premises reasonably required to clean the Demised Premises as required under
Section 20.02.

     20.04.  Landlord shall furnish adequate hot and cold water to the Demised
Premises for drinking, lavatory and cleaning purposes.  If Tenant uses water for
any other purpose Landlord may install and maintain, at Tenant's expense, meters
to measure Tenant's consumption of cold water and/or hot water for such other
purpose.  Tenant shall reimburse Landlord for the quantities of cold water and
hot water shown on such meters on demand.

                     ARTICLE 21 - ACCESS, CHANGES AND NAME


     21.01.  Except for the space within the inside surfaces of all walls, hung
ceilings, floors, windows and doors bounding the Demised Premises, all of the
Building, including, without limitation, exterior Building walls, core corridor
walls and doors and any core corridor entrance, any terraces or roofs adjacent
to the Demised Premises, and any space in or adjacent to the Demised Premises
used for shafts, stacks, pipes, conduits, fan rooms, ducts, electric or other
utilities, sinks or other Building facilities and the use thereof, as well as
access thereto through the Demised Premises (subject to the provisions of
Section 21.04 hereof) for the purpose of operating, maintenance, decoration and
repair, are reserved to Landlord.  Landlord also reserves the right, to install,
erect, use and maintain pipes, ducts and conduits in and through the Demised
Premises, provided such are properly enclosed, do not materially reduce Tenant's
usable facilities or unreasonably interfere with Tenant's use of the Demised
Premises.  Any dispute with regard thereto may be submitted to arbitration in
accordance with Article 36.

     21.02.  Landlord and its agents shall have the right to enter and/or pass
through the Demised Premises at any time or times, upon not less than one (1)
days prior notice (except that no such notice shall be required in cases of
emergency) (a) to examine the Demised Premises and to show them to actual and
prospective Superior Lessors, Superior Mortgagees, or prospective purchasers of
the Building, and (b) to make such repairs, alterations, additions and
improvements in or to the Demised Premises and/or in or to the Building or its
facilities and equipment as Landlord is required or desires to make (subject to
the provisions of Section 21.04 hereof).  Landlord shall (subject to the
provisions of Section 21.04 hereof) be allowed to take all materials into and
upon the Demised Premises that may be required in connection therewith, without
any liability to Tenant and without any reduction of Tenant's obligations
hereunder.  During the period of twelve (12) months prior to the Expiration
Date, Landlord and its agents may exhibit the Demised Premises to prospective
tenants.

     21.03.  If at any time any windows of the Demised Premises are temporarily
darkened or obstructed by reason of any repairs, improvements, maintenance
and/or cleaning in or about the Building, or if any part of the Building or the
Common Areas, other than the Demised Premises,

                                       33
<PAGE>

is temporarily or permanently closed or inoperable, the same shall not be deemed
a constructive eviction and shall not result in any reduction or diminution of
Tenant's obligations under this Lease.

     21.04.  Landlord reserves the right, at any time and from time to time, to
make such changes, alterations, additions and improvements in or to the Building
and the fixtures and equipment thereof as Landlord shall deem necessary or
desirable. In all such events, such repairs and changes shall be commenced and
prosecuted diligently by Landlord in a good and workmanlike manner and with as
little interference as practicable with Tenant's access to and use of the
Building and the Demised Premises. Nothing contained herein shall be construed,
however, as requiring Landlord to perform such work at times other than Monday
through Friday Business Days and during Business Hours except in cases of
emergency. In the event that any such work or repairs shall require Tenant to
either: switch to backup power, or vacate the Demised Premises, Landlord shall,
except in cases of emergency where such notice is not practicable, provide
Tenant with not less than twenty-five (25) days prior notice of such work or
repair to permit Tenant to coordinate utilization of its backup equipment and
facilities, if required.

     21.05.  Landlord may adopt any name for the Building.  Landlord reserves
the right to change the name and/or address of the Building at any time.

                 ARTICLE 22 - MECHANICS' LIENS AND OTHER LIENS


     22.01.  Nothing contained in this Lease shall be deemed, construed or
interpreted to imply any consent or agreement on the part of Landlord to subject
Landlord's interest or estate to any liability under any mechanic's or other
lien law.  If any mechanic's or other lien or any notice of intention to file a
lien is filed against the Land, or any part thereof, or the Demised Premises, or
any part thereof, for any work, labor, service or materials claimed to have been
performed or furnished for or on behalf of Tenant or anyone holding any part of
the Demised Premises through or under Tenant, Tenant shall cause the same to be
canceled and discharged of record by payment, bond or order of a court of
competent jurisdiction promptly, but in no event later than (20) days after
notice by Landlord to Tenant.

                           ARTICLE 23 - NON-LIABILITY


     23.01.  Subject to the provisions of Section 13.04 (b) of this Lease,
neither Landlord nor any partner, joint venturer, director, officer, agent,
servant or employee of Landlord shall be liable to Tenant for any loss, injury
or damage to Tenant or to any other Person, or to its or their property,
irrespective of the cause of such injury, damage or loss, unless caused by or
resulting from the negligence or intentional tortious act of Landlord, its
agents, servants or employees in the operation or maintenance of the Land or
Building without negligence or other tortious conduct on the part of Tenant or
any of its subtenants or licensees or its or their employees, agents or
contractors.  Further, neither Landlord nor any partner, joint venturer,
director, officer, agent,

                                       34
<PAGE>

servant or employee of Landlord shall be liable for, nor shall the provisions of
Section 13.04(b) apply with respect to (a) any such damage caused by other
tenants or Persons in, upon or about the Land or Building, or caused by
operations in construction of any private, public or quasi-public work; or (b)
even if negligent or culpable, for consequential damages arising out of any loss
of use of the Demised Premises or any equipment or facilities therein by Tenant
or any Person claiming through or under Tenant.

     23.02.  [Intentionally Omitted.]

     23.03.  Notwithstanding any provision to the contrary, Tenant shall look
solely to the estate and property of Landlord in and to the Land and Building
(and the proceeds of insurance maintained with respect to the Building, or
received by Landlord from a sale of such estate and property, but not the
proceeds of any financing or refinancing thereof) in the event of any claim
against Landlord arising out of or in connection with this Lease, the
relationship of Landlord and Tenant or Tenant's use of the Demised Premises or
the Common Areas, and Tenant agrees that the liability of Landlord arising out
of or in connection with this Lease, the relationship of Landlord and Tenant or
Tenant's use of the Demised Premises or the Common Areas shall be limited to
such estate and property of Landlord (or such insurance or sale proceeds).  No
other properties or assets of Landlord or any partner, joint venturer, director,
officer, agent, servant or employee of Landlord shall be subject to levy,
execution or other enforcement procedures for the satisfaction of any judgement
(or other judicial process) or for the satisfaction of any other remedy of
Tenant arising out of, or in connection with, this Lease, the relationship of
Landlord and Tenant or Tenant's use of the Demised Premises or the Common Areas
and if Tenant shall acquire a lien on or interest in any other properties or
assets by judgment or otherwise, Tenant shall promptly release such lien on or
interest in such other properties and assets by executing, acknowledging and
delivering to Landlord an instrument to that effect prepared by Landlord's
attorneys.  Tenant hereby waives the right of specific performance and any other
remedy allowed in equity if specific performance or such other remedy could
result in any liability of Landlord for the payment of money to Tenant, or to
any court or governmental authority (by way of fines or otherwise) for
Landlord's failure or refusal to observe a judicial decree or determination, or
to any third party.

                       ARTICLE 24 - DAMAGE OR DESTRUCTION


     24.01.  If the Building or the Demised Premises shall be partially or
totally damaged or destroyed by fire or other casualty (and if this Lease shall
not be terminated as in this Article 24 hereinafter provided), Landlord shall
repair the damage and restore and rebuild the Building and/or the Demised
Premises (except for the Tenant's Property) with reasonable dispatch after
notice to it of the damage or destruction and the collection of the insurance
proceeds attributable to such damage.

     24.02.  Subject to the provisions of Section 24.05, if all or part of the
Demised Premises shall be damaged or destroyed or rendered completely or
partially untenantable on account of fire

                                       35
<PAGE>

or other casualty, or if a portion of the Building shall be damaged or destroyed
or rendered completely or partially untenantable on account of fire or other
casualty and such damage or destruction prevents Tenant from occupying the
Demised Premises, the Rent shall be abated or reduced, as the case may be, in
the proportion that the untenantable area of the Demised Premises bears to the
total area of the Demised Premises, for the period from the date of the damage
or destruction to (a) the date the damage to the Demised Premises shall be
substantially repaired, or (b) if the Building and not the Demised Premises is
so damaged or destroyed, the date on which the Demised Premises shall be made
tenantable; provided, however, should Tenant reoccupy a portion of the Demised
Premises during the period the repair or restoration work is taking place and
prior to the date that the Demised Premises are substantially repaired or made
tenantable the Rent allocable to such reoccupied portion, based upon the
proportion which the area of the reoccupied portion of the Demised Premises
bears to the total area of the Demised Premises, shall be payable by Tenant from
the date of such occupancy.

     24.03.  If (a) the Building or the Demised Premises shall be totally
damaged or destroyed by fire or other casualty, or (b) the Building shall be so
damaged or destroyed by fire or other casualty (whether or not the Demised
Premises are damaged or destroyed) that its repair or restoration requires the
expenditure, as estimated by a reputable contractor or architect designated by
Landlord, of more than twenty percent (20%) (or ten percent [10%] if such
casualty occurs during the last two [2] years of the Term) of the full insurable
value of the Building immediately prior to the casualty, then in either such
case Landlord may terminate this Lease by giving Tenant notice to such effect
within ninety (90) days after the date of the fire or other casualty. Landlord's
right to terminate the Lease pursuant to this paragraph 24.03 in the event of
damage or destruction which does not include the Demised Premises, shall be
conditioned on Landlord terminating all other space leases in the Building to
the extent Landlord shall have such right.

     24.04.  Tenant shall not be entitled to terminate this Lease (except as
provided in Section 24.08), as the result of any damage or destruction of the
Building or the Demised Premises. No damages, compensation or claim shall be
payable by Landlord for inconvenience, loss of business or annoyance arising
from any repair or restoration of any portion of the Demised Premises or of the
Building pursuant to this Article 24.  Landlord shall use its best efforts to
make such repair or restoration promptly and in such manner as not unreasonably
to interfere with Tenant's use and occupancy of the Demised Premises, but
Landlord shall not be required to do such repair or restoration work except
during Business Hours on Business Days. In the event that any such work or
repairs shall require Tenant to either: switch to backup power, or vacate the
Demised Premises, Landlord shall, except in cases of emergency where such notice
is not practicable, provide Tenant with not less than twenty-five (25) days
prior notice of such work or repair to permit Tenant to coordinate utilization
of its backup equipment and facilities, if required.


     24.05.  Notwithstanding any of the foregoing provisions of this Article 24,
if by reason of some act or omission on the part of Tenant or any of its
subtenants or its or their partners, directors, officers, servants, employees,
agents or contractors, either (a) Landlord or any Superior Lessor or any
Superior Mortgagee shall be unable to collect all of the insurance proceeds

                                       36
<PAGE>

(including, without limitation, rent insurance proceeds) applicable to damage or
destruction of the Demised Premises or the Building by fire or other casualty,
or (b) the Demised Premises or the Building shall be damaged or destroyed or
rendered completely or partially untenantable on account of fire or other
casualty, then, without prejudice to any other remedies which may be available
against Tenant, there shall be no abatement or reduction of the Rent, except to
the extent Landlord receives the proceeds of rent insurance with respect to the
Rent which would have been payable by Tenant with respect to Demised Premises.
Further, nothing contained in this Article 24 shall relieve Tenant from any
liability that may exist as a result of any damage or destruction by fire or
other casualty.

     24.06.  Landlord will not carry insurance of any kind on the Tenant's
Property, and, except as provided by law or by reason of Landlord's breach of
any of its obligations hereunder, shall not be obligated to repair any damage to
or replace the Tenant's Property.

     24.07.  The provisions of this Article 24 shall be deemed an express
agreement governing any case of damage or destruction of the Demised Premises
and/or Building by fire or other casualty, and any law providing for such a
contingency in the absence of an express agreement, now or hereafter in force,
shall have no application in such case.

     24.08  In the event of (i) damage or destruction with respect to the
Demised Premises which prevents the use and occupancy of more than fifty (50%)
of the Demised Premises by Tenant, or (ii) damage or destruction with respect to
the Building the repair or restoration of which requires the expenditure, as
estimated by a reputable contractor or architect designated by Landlord, of more
than twenty-five percent (25%) of the full insurable value of the Building
immediately prior to the casualty, then in either of such events Landlord shall
and Tenant (provided Tenant is not in monetary default under this Lease beyond
any applicable notice and cure period and such damage or destruction prevents
the use and occupancy of the Demised Premises by Tenant) shall have the right to
request within thirty (30) days after such event the Architect to determine the
estimated time for restoration.  The Landlord shall cause the Architect to
provide notice to Landlord and Tenant of such determination (the "Architect's
Notice") within thirty (30) days after notice from Landlord or Tenant requesting
such determination. Any dispute with respect to such determination may be
submitted to arbitration pursuant to Article 36 of this Lease. If the Architect
determines that the restoration of same is estimated to take more than twelve
(12) months from the date of the casualty, Landlord and Tenant shall each
(provided, however that Tenant's right shall be conditioned upon (i) Tenant not
being in monetary or material non-monetary default under this Lease beyond any
applicable notice and cure period and (ii) Tenant being prevented from using and
occupying the Demised Premises for a period of not less than twelve months as
estimated by such contractor or architect; and Landlord's right shall be
conditioned on Landlord terminating all other space leases in the Building to
the extent Landlord shall have such right) have the right to terminate this
Lease, upon thirty (30) days prior written notice to the other, given within
thirty (30) days of the Architect's Notice.  Landlord's right to terminate the
Lease pursuant to this Section shall be in addition to and not in limitation of
Landlord's other rights pursuant to this Article 24. Nothing contained herein
shall be construed as limiting Landlord's right to

                                       37
<PAGE>

collect the full amount of the proceeds of rent insurance or business
interruption insurance. If, such restoration is not substantially completed with
respect to the Demised Premises within eleven (11) months from the date of the
casualty (which period may be extended by Landlord up to six (6) months by
reason of Unavoidable Delays) (herein the "Restoration Period"), Tenant shall
have the right, upon not less than thirty (30) days prior written notice given
not later than the thirty (30) days prior to the expiration of the Restoration
Period, to terminate this Lease, unless Landlord is diligently proceeding with
such repairs and such restoration is substantially completed within such thirty
(30) day notice period.


                          ARTICLE 25 - EMINENT DOMAIN


     25.01  If the whole of the Demised Premises shall be taken by any public or
quasi-public authority under the power of condemnation, eminent domain or
expropriation, or in the event of conveyance of the whole of the Demised
Premises in lieu thereof, this Lease shall terminate as of the day possession
shall be taken by such authority.  If 25% or less of the Floor Space of the
Demised Premises shall be so taken or conveyed, this Lease shall terminate only
in respect of the part so taken or conveyed as of the day possession shall be
taken by such authority.  If more than 25% of the Floor Space of the Demised
Premises shall be so taken or conveyed, this Lease shall terminate only in
respect of the part so taken or conveyed as of the day possession shall be taken
by such authority, but either party shall have the right to terminate this Lease
upon notice given to the other party within 30 days after such taking
possession.  If more than 25% of the Floor Space of the Building shall be so
taken or conveyed, Landlord may, by notice to Tenant, terminate this Lease as of
the day possession shall be taken.  If so much of the parking facilities shall
be so taken or conveyed that the number of parking spaces necessary, in
Landlord's reasonable judgment, for the continued operation of the Building
shall not be available, Landlord shall, by notice to Tenant, terminate this
Lease as of the day possession shall be taken.  If this Lease shall continue in
effect as to any portion of the Demised Premises not so taken or conveyed, the
Rent shall be computed as of the day possession shall be taken on the basis of
the remaining Floor Space of the Demised Premises.  Except as specifically
provided herein, in the event of any such taking or conveyance there shall be no
reduction in Rent.  If this Lease shall continue in effect, Landlord shall, at
its expense, but shall be obligated only to the extent of the net award or other
compensation (after deducting all expenses in connection with obtaining same)
available to Landlord for the improvements taken or conveyed (excluding any
award or other compensation for land or for the unexpired portion of the term of
any Superior Lease), make all necessary alterations so as to constitute the
remaining Building a complete architectural and tenantable unit, except for the
Tenant's Property, and Tenant shall make all alterations or replacements to the
Tenant's Property and decorations in the Demised Premises.  All awards and
compensation for any taking or conveyance, whether for the whole or a part of
the Land or Building, the Demised Premised or otherwise, shall be the property
of Landlord, and Tenant hereby assigns to Landlord all of Tenant's right, title
and interest in and to any and all such awards and compensation, including,
without limitation, any award or compensation for the value of the unexpired
portion of the Term.  Tenant shall be entitled to claim, prove and receive in
the condemnation proceeding

                                       38
<PAGE>

such award or compensation as may be allowed for the Tenant's Property and for
loss of business, good will, and depreciation or injury to and cost of removal
of the Tenant's Property, but only if such award or compensation shall be made
by the condemning authority in addition to, and shall not result in a reduction
of, the award or compensation made by it to Landlord.

     25.02.  If the temporary use or occupancy of all or any part of the Demised
Premises shall be taken during the Term, Tenant shall be entitled, except as
hereinafter set forth, to receive that portion of the award or payment for such
taking which represents compensation for the use and occupancy of the Demised
Premises, for the taking of the Tenant's Property and for moving expenses, and
Landlord shall be entitled to receive that portion which represents
reimbursement for the cost of restoration of the Demised Premises.  This Lease
shall be and remain unaffected by such taking and Tenant shall continue to be
responsible for all of its obligations hereunder insofar as such obligations are
not affected by such taking and shall continue to pay the Rent in full when due.
If the period of temporary use or occupancy shall extend beyond the Expiration
Date, that part of the award or payment which represents compensation for the
use and occupancy of the Demised Premises (or a part thereof) shall be divided
between Landlord and Tenant so that Tenant shall receive (except as otherwise
provided below) so much thereof as represents compensation for the period up to
and including the Expiration Date and Landlord shall receive so much thereof as
represents compensation for the period after the Expiration Date.  All monies to
be paid to Tenant as, or as part of, an award or payment for temporary use and
occupancy for a period beyond the date to which the Rent has been paid shall be
received, held and applied by the first Superior Mortgagee (or if there is no
Superior Mortgagee, by Landlord as a trust fund) for payment of the Rent
becoming due hereunder.

                             ARTICLE 26 - SURRENDER


     26.01.  On the Expiration Date, or upon any earlier termination of this
Lease, or upon any re-entry by Landlord upon the Demised Premises, Tenant shall
quit and surrender the Demised Premises to Landlord "broom-clean" and in good
order, condition and repair, except for ordinary wear and tear and such damage
or destruction as Landlord is required to repair or restore under this Lease,
and Tenant shall remove all of Tenant's Property therefrom except as otherwise
expressly provided in this Lease.

     26.02.  If Tenant remains in possession of the Demised Premises after the
expiration of the Term, Tenant shall be deemed to be occupying the Demised
Premises at the sufferance of Landlord subject to all of the provisions of this
Lease, except that the monthly Fixed Rent shall be one and one quarter times the
Fixed Rent in effect during the last month of the Term for the first month of
such holdover, one and one half times the Fixed Rent in effect during the last
month of the Term for the second month of such holdover, one and three quarters
times the Fixed Rent in effect during the last month of the Term for the third
month of such holdover, and thereafter twice the Fixed Rent in effect during the
last month of the Term.

     26.03.  No act or thing done by Landlord or its agents shall be deemed an
acceptance of

                                       39
<PAGE>

a surrender of the Demised Premises, and no agreement to accept such surrender
shall be valid unless in writing and signed by Landlord.

                     ARTICLE 27 - CONDITIONS OF LIMITATION


     27.01.  This Lease is subject to the limitation that whenever Tenant or any
Guarantor (a) shall make an assignment for the benefit of creditors, or (b)
shall commence a voluntary case or have entered against it an order for relief
under any chapter of the Federal Bankruptcy Code (Title 11 of the United States
Code) or any similar order or decree under any federal or state law, now in
existence, or hereafter enacted having the same general purpose, and such order
or decree shall have not been stayed or vacated within 60 days after entry, or
(c) shall cause, suffer, permit or consent to the appointment of a receiver,
trustee, administrator, conservator, sequestrator, liquidator or similar
official in any federal, state or foreign judicial or nonjudicial proceeding, to
hold, administer and/or liquidate all or substantially all of its assets, and
such appointment shall not have been revoked, terminated, stayed or vacated and
such official discharged of his duties within 60 days of his appointment, then
Landlord, at any time after the occurrence of any such event, may give Tenant a
notice of intention to end the Term at the expiration of five (5) days from the
date of service of such notice of intention, and upon the expiration of said
five (5) day period, whether or not the Term shall theretofore have commenced,
this Lease shall terminate with the same effect as if that day were the
expiration date of this Lease, but Tenant shall remain liable for damages as
provided in Article 29.

     27.02.  This Lease is subject to the further limitations that: (a) if
Tenant shall default in the payment of any Rent and such Rent shall not be paid
within five (5) days after notice or invoice, or (b) if Tenant shall, whether by
action or inaction, be in default of any of its obligations under this Lease
(other than a default in the payment of Rent) and such default shall continue
and not be remedied within twenty (20) days after Landlord shall have given to
Tenant a notice specifying the same, or, in the case of a default which cannot
with due diligence be cured within a period of twenty (20) days and the
continuance of which for the period required for cure will not subject Landlord
or any Superior Lessor to prosecution for a crime (as more particularly
described in the last sentence of Section 12.02) or termination of any Superior
Lease or foreclosure of any Superior Mortgage, if Tenant shall not, (i) within
said twenty (20) day period advise Landlord of Tenant's intention to take all
steps necessary to remedy such default, (ii) duly commence within said twenty
(20) day period, and thereafter diligently prosecute to completion all steps
necessary to remedy the default, and (iii) complete such remedy within a
reasonable time after the date of said notice by Landlord, or (c) if any event
shall occur or any contingency shall arise whereby this Lease would, by
operation of law or otherwise, devolve upon or pass to any person, firm or
corporation other than Tenant, except as expressly permitted by Article 11, then
in any of said cases Landlord may give to Tenant a notice of intention to end
the Term at the expiration of five (5) days from the date of the service of such
notice of intention, and upon the expiration of said five (5) days, whether or
not the Term shall theretofore have commenced, this Lease shall terminate with
the same effect as if that day were the expiration date of this Lease, but
Tenant shall remain liable for damages as provided in Article 29.

                       ARTICLE 28 - RE-ENTRY BY LANDLORD


     28.01.  If Tenant shall default in the payment of any Rent and such Rent
shall not be paid within five (5) days after notice or invoice, or if this Lease
shall terminate as provided in Article 27, Landlord or Landlord's agents and
employees may immediately or at any time thereafter re-enter the Demised
Premises, or any part thereof, either by summary dispossess proceedings or by
any suitable action or proceeding at law without being liable to indictment,
prosecution or damages therefor, and may repossess the same, and may remove any
Person therefrom, to the end that Landlord may have, hold and enjoy the Demised
Premises.  The word "re-enter," as used herein, is not restricted to its
technical legal meaning.  If this Lease is terminated under the provisions of
Article 27, or if Landlord shall re-enter the Demised Premises under the
provisions of this Article 28,  or in the event of the termination of this
Lease, or of re-entry, by or under any summary dispossess or other proceedings
or action by reason of default hereunder on the part of Tenant, Tenant shall
thereupon pay to Landlord the Rent payable up to the time of such termination of
this Lease, or of such recovery of possession of the Demised Premises by
Landlord, as the case may be, and shall also pay to Landlord damages as provided
in Article 29.

     28.02.  In the event of a breach or threatened breach by Tenant of any of
its obligations under this Lease, Landlord shall also have the right of
injunction.  The special remedies to which Landlord may resort hereunder are
cumulative and are not intended to be exclusive of any other remedies to which
Landlord may lawfully be entitled at any time and Landlord may invoke any remedy
allowed at law or in equity as if specific remedies were not provided for
herein.

     28.03.  If this Lease shall terminate under the provisions of Article 27,
or if Landlord shall re-enter the Demised Premises under the provisions of this
Article 28, or in the event of the termination of this Lease, or of re-entry, by
or under any summary dispossess or other proceeding or action by reason of
default hereunder on the part of Tenant, Landlord shall be entitled to retain
all monies, if any, paid by Tenant to Landlord, whether as Advance Rent,
security or otherwise, but such monies shall be credited by Landlord against any
Rent due from Tenant at the time of such termination or re-entry or, at
Landlord's option, against any damages payable by Tenant under Article 29 or
pursuant to law.

                              ARTICLE 29 - DAMAGES


     29.01.  If this Lease is terminated under the provisions of Article 27, or
if Landlord shall re-enter the Demised Premises under the provisions of Article
28, or in the event of the termination of this Lease, or of re-entry, by or
under any summary dispossess or other proceeding or action or any provision of
law by reason of default hereunder on the part of Tenant, Tenant shall pay as
Additional Charges to Landlord, at the election of Landlord, either or any
combination (but without duplication) of:

                                       41
<PAGE>

     (a)  a sum which at the time of such termination of this Lease or at the
     time of any such re-entry by Landlord, as the case may be, represents the
     then value of the excess, if any, of (i) the aggregate amount of the Rent
     which would have been payable by Tenant (conclusively presuming the average
     monthly Additional Charges to be the same as were the average monthly
     Additional Charges payable for the year, or if less than 365 days have then
     elapsed since the Commencement Date, the partial year, immediately
     preceding such termination or re-entry) for the period commencing with such
     earlier termination of this Lease or the date of any such re-entry, as the
     case may be, and ending with the Expiration Date, over (ii) the aggregate
     rental value of the Demised Premises for the same period; or

     (b)  sums equal to the Fixed Rent and the Additional Charges which would
     have been payable by Tenant had this Lease not so terminated, or had
     Landlord not so re-entered the Demised Premises, payable upon the due dates
     therefor specified herein following such termination or such re-entry and
     until the Expiration Date, provided, however, that if Landlord shall relet
     the Demised Premises during said period, Landlord shall credit Tenant with
     the net rents received by Landlord from such reletting, such net rents to
     be determined by first deducting from the gross rents as and when received
     by Landlord from such reletting the expenses incurred or paid by Landlord
     in terminating this Lease or in re-entering the Demised Premises and in
     securing possession thereof, as well as the expenses of reletting,
     including, without limitation, altering and preparing the Demised Premises
     for new tenants, brokers' commissions, legal fees, and all other expenses
     properly chargeable against the Demised Premises and the rental therefrom,
     it being understood that any such reletting may be for a period shorter or
     longer than the period ending on the Expiration Date; but in no event shall
     Tenant be entitled to receive any excess of such net rents over the sums
     payable by Tenant to Landlord hereunder, nor shall Tenant be entitled in
     any suit for the collection of damages pursuant to this subsection (b) to a
     credit in respect of any rents from a reletting, except to the extent that
     such net rents are actually received by Landlord.  If the Demised Premises
     or any part thereof should be relet in combination with other space, then
     proper apportionment on a square foot basis shall be made of the rent
     received from such reletting and of the expenses of reletting.

     If the Demised Premises or any part thereof should be relet by Landlord
before presentation of proof of such damages to any court, commission or
tribunal, the amount of rent reserved upon such reletting shall be presumed to
be the fair and reasonable rental value for the Demised Premises, or part
thereof, so relet during the term of the reletting.  Landlord shall not be
liable in any way whatsoever for its failure to relet the Demised Premises or
any part thereof, or if the Demised Premises or any part thereof are relet, for
its failure to collect the rent under such reletting, and no such failure to
relet or failure to collect rent shall release or affect Tenant's liability for
damages or otherwise under this Lease. Landlord shall use commercially
reasonable efforts to relet the Demised Premises to mitigate Landlord's damages.
In addition to any other damages recoverable by Landlord pursuant to Section
29.01 hereof, Landlord shall be entitled, in addition to such costs and expenses
as Landlord may incur or be entitled to recover from Tenant, a reletting fee in
amount equal to two and one half percent (2-1/2%) of the gross rentals

                                       42
<PAGE>

payable under any lease(s) entered into with any replacement tenant(s) for the
Demised Premises or any part thereof for the portion of the term of the lease
entered into with the replacement tenant which is co-terminous with the term of
this Lease (herein the "Reletting Override"). The parties agree that the
Reletting Override is fair and reasonable and that such fee shall be in addition
to any brokerage fees or commissions payable to third parties. For the purposes
hereof, "commercially reasonable efforts" shall mean the following actions,
which actions shall create an irrebuttable presumption that Landlord has
fulfilled such obligation: (i) Landlord shall include the availability of the
Demised Premises in Landlord's monthly listing to brokers (if any), commencing
with the first such report (if any) issued following Landlord's recovery of
possession of the Demised Premises, and ending upon re-leasing of the Demised
Premises; and (ii) Landlord shall include the availability of the Demised
Premises in Landlord's periodic real estate guide (if any), commencing with the
first such guide (if any) issued following Landlord's recovery of possession of
the Demised Premises, and ending upon re-leasing of the Demised Premises; and
(iii) Landlord shall hold an "Open House" for the Demised Premises within sixty
(60) days of Landlord's recovery of possession of the Demised Premises, or (iv)
in lieu of (i), (ii) and (iii) of this paragraph, upon Tenant's written request,
Landlord shall engage an independent commercial real estate broker to relet the
Demised Premises, the cost and expense of which shall be an element of
Landlord's damages in addition to any other damages recoverable pursuant to
Section 29.01 hereof. Nothing contained herein shall require Landlord to relet
the Demised Premises prior to or with any preference over the leasing of any
other similar premises of Landlord or any affiliate of Landlord, nor shall any
rental of such other premises reduce the damages which Landlord would be
entitled to recover from Tenant. In the event Tenant, on behalf of itself or any
and all persons claiming through or under Tenant, attempts to raise a defense or
assert any affirmative obligations on Landlord's part to mitigate such damages
or relet the Demised Premises other than a defense or assertion that Landlord
has failed to mitigate damages as expressly provided in this Section, Tenant
shall reimburse Landlord for any costs and expenses incurred by Landlord as a
result of any such defense or assertion, including but not limited to Landlord's
attorneys' fees incurred in connection therewith.

     29.02.  Suit or suits for the recovery of such damages or, any installments
thereof, may be brought by Landlord at any time and from time to time at its
election, and nothing contained herein shall be deemed to require Landlord to
postpone suit until the date when the Term would have expired if it had not been
so terminated under the provisions of Article 27, or under any provision of law,
or had Landlord not re-entered the Demised Premises.  Nothing herein contained
shall be construed to limit or preclude recovery by Landlord against Tenant of
any sums or damages to which, in addition to the damages particularly provided
above, Landlord may lawfully be entitled by reason of any default hereunder on
the part of Tenant.  Nothing herein contained shall be construed to limit or
prejudice the right of Landlord to prove for and obtain as damages by reason of
the termination of this Lease or re-entry of the Demised Premises for the
default of Tenant under this Lease, an amount equal to the maximum allowed by
any statute or rule of law in effect at the time, whether or not such amount be
greater than, equal to, or less than any of the sums referred to in Section
29.01. 29.03.  In addition, if this Lease is terminated under the provisions of
Article 27, or if Landlord shall re-enter the Demised Premises under the
provisions of Article 28, Tenant covenants that:  (a) the Demised Premises then
shall be in the

                                       43
<PAGE>

same condition as that in which Tenant has agreed to surrender the same to
Landlord at the Expiration Date; (b) Tenant shall have performed prior to any
such termination any obligation of Tenant contained in this Lease for the making
of any alteration or for restoring or rebuilding the Demised Premises or the
Building, or any part thereof; and (c) for the breach of any covenant of Tenant
set forth above in this Section 29.03, Landlord shall be entitled immediately,
without notice or other action by Landlord, to recover, and Tenant shall pay, as
and for liquidated damages therefor, the cost of performing such covenant (as
estimated by an independent contractor selected by Landlord).

     29.04.  In addition to any other remedies Landlord may have under this
Lease, and without reducing or adversely affecting any of Landlord's rights and
remedies under this Article 29, if any Rent or damages payable hereunder by
Tenant to Landlord are not paid upon demand therefor, the same shall bear
interest at the Late Payment Rate or the maximum rate permitted by law,
whichever is less, from the due date thereof until paid, and the amounts of such
interest shall be Additional Charges hereunder.

     29.05.  In addition to any remedies which Landlord may have under this
Lease, if there shall be a default hereunder by Tenant which shall not have been
remedied within the applicable grace period, Landlord shall not be obligated to
furnish to Tenant or the Demised Premises any HVAC services outside of Business
Hours or Business Days, or any extra or additional cleaning services; and the
discontinuance of any one or more such services shall be without liability by
Landlord to Tenant and shall not reduce, diminish or otherwise affect any of
Tenant's covenants and obligations under this Lease.

                        ARTICLE 30 - AFFIRMATIVE WAIVERS


     30.01.  Tenant, on behalf of itself and any and all persons claiming
through or under Tenant, does hereby waive and surrender all right and privilege
which it, they or any of them might have under or by reason of any present or
future law, to redeem the Demised Premises or to have a continuance of this
Lease after being dispossessed or ejected from the Demised Premises by process
of law or under the terms of this Lease or after the termination of this Lease
as provided in this Lease.

     30.02.  Landlord and Tenant hereby waive trial by jury in any action,
proceeding or counterclaim brought by either against the other on any matter
whatsoever arising out of or in any way connected with this Lease, the
relationship of Landlord and Tenant, and Tenant's use or occupancy of the
Demised Premises and use of the Common Area, including, without limitation, any
claim of injury or damage, and any emergency and other statutory remedy with
respect thereto.  Tenant shall not interpose any counterclaim of any kind in any
action or proceeding commenced by Landlord to recover possession of the Demised
Premises, other than mandatory or compulsory counterclaims.

                                       44
<PAGE>

                            ARTICLE 31 - NO WAIVERS


     31.01.  The failure of either party to insist in any one or more instances
upon the strict performance of any one or more of the obligations of this Lease,
or to exercise any election herein contained, shall not be construed as a waiver
or relinquishment for the future of the performance of such one or more
obligations of this Lease or of the right to exercise such election, but the
same shall continue and remain in full force and effect with respect to any
subsequent breach, act or omission.  The receipt by Landlord of Fixed Rent or
Additional Charges with knowledge of breach by Tenant of any obligation of this
Lease shall not be deemed a waiver of such breach.

                     ARTICLE 32 - CURING TENANT'S DEFAULTS


     32.01.  If Tenant shall default in the performance of any of Tenant's
obligations under this Lease beyond any applicable notice and cure periods,
Landlord, without thereby waiving such default, may (but shall not be obligated
to) perform the same for the account and at the expense of Tenant, without
notice in a case of emergency, and in any other case only if such default
continues after the expiration of twenty (20) days from the date Landlord gives
Tenant notice of the default.  Any costs or expenses incurred by Landlord in
connection with any such performance by it for the account of Tenant, and
interest on all sums advanced by Landlord under this Article at the Late Payment
Rate or the maximum rate permitted by law, whichever is less, shall be payable
by Tenant within thirty (30) days of demand and, in addition to any other rights
or remedies of Landlord under this Lease, any bills received by Landlord for
same may be sent by Landlord to Tenant for payment by Tenant monthly, or
immediately, at Landlord's option.

     32.02.  If Landlord shall default in the performance of any of Landlord's
obligations under this Lease beyond any applicable notice or cure period,
Tenant, without thereby waiving such default, may (but shall not be obligated
to) perform the same for the account and at the expense of Landlord, without
notice in a case of emergency posing a threat to life or safety, and in any
other case only if such default continues after the expiration of sixty (60)
days from the date Tenant gives Landlord notice of the default, unless Landlord
has commenced and is then diligently pursuing such cure. In the event of an
emergency (such emergency posing a threat to life or safety) Tenant shall have
the right to perform such obligation itself and seek reimbursement from
Landlord, but Tenant shall, where practicable, endeavor to give Landlord
reasonable notice and the opportunity to cure such emergency. Any costs or
expenses incurred by Tenant in connection with any such performance by it for
the account of Landlord, and interest on all sums advanced by Tenant under this
Article at the rate of ten percent (10%) per annum, or the maximum rate
permitted by law, whichever is less, shall be payable by Landlord within thirty
(30) days of demand and, in addition to any other rights or remedies of Tenant
under this Lease, any bills received by Tenant for same may be sent by Tenant to
Landlord for payment by Landlord monthly, or immediately, at Tenant's option. In
no event shall the failure of Landlord to perform any repair or other obligation
which is the subject matter hereof, whether or not requested by Tenant, be
deemed to be an acknowledgment that the Landlord had a duty or obligation to
perform the same. In the event Landlord disputes the necessity of the
performance

                                       45
<PAGE>

of the repair or other obligation in question, its obligations to make same, or
the cost thereof, or if Landlord fails to pay same when due hereunder, Tenant's
remedy shall, subject to Landlord's and Tenant's option to require arbitration
of such claim under Article 36 hereof, be an action at law to recover such
claimed amount and Tenant shall not, in any case, be entitled to any offsets or
deductions from Rent. Nothing contained in this Section 32.02 shall be construed
to allow or permit Tenant to deduct or offset or reduce any amounts due against
any Rent under this Lease.

  32.03.  In any litigation between the parties regarding this Lease, the losing
party shall pay to the prevailing party all reasonable expenses and court costs
including reasonable attorney's fees incurred by the prevailing party.  A party
shall be considered the prevailing party if:

  (i)  it initiated the litigation and substantially obtains the relief it
sought, either through a judgment or the losing party's voluntary action before
arbitration (after it is scheduled), trial, or judgment; or

  (ii)  the other party withdraws its action without substantially obtaining the
relief it sought.



                              ARTICLE 33 - BROKER


     33.01.  Tenant represents that no broker except the Broker was instrumental
in bringing about or consummating this Lease and that Tenant had no
conversations or negotiations with any broker except the Broker concerning the
leasing of the Demised Premises.  Tenant agrees to indemnify and hold harmless
Landlord against and from any claims for any brokerage commissions and all
costs, expenses and liabilities in connection therewith, including, without
limitation, attorneys' fees and expenses, arising out of any conversations or
negotiations had by Tenant with any broker other than the Broker.  Landlord
shall pay any brokerage commissions due the Broker pursuant to a separate
agreement between Landlord and the Broker.

                              ARTICLE 34 - NOTICES


     34.01.  Any notice, statement, demand, consent, approval or other
communication required or permitted to be given, rendered or made by either
party to the other, pursuant to this Lease or pursuant to any applicable Legal
Requirement, shall be in writing and shall be deemed to have been properly
given, rendered or made only if hand delivered, sent by recognized overnight
courier providing receipted delivery, such as Federal Express, or UPS, or sent
by United States registered or certified mail, return receipt requested,
addressed to the other party at the address hereinabove set forth (except that
after the Commencement Date, Tenant's address, unless Tenant shall give notice
to the contrary, shall be the Building), as to Tenant to the attention of

                                       46
<PAGE>

General Counsel and as to Landlord, to the attention of General Counsel with a
concurrent notice to the attention of Controller, and shall be deemed to have
been given, rendered or made on the day of delivery or refusal.  Either party
may, by notice as aforesaid, designate a different address or addresses for
notices, statements, demands, consents, approvals or other communications
intended for it.  In addition, upon and to the extent requested by Landlord,
copies of notices shall be sent to the Superior Mortgagee.

                       ARTICLE 35 - ESTOPPEL CERTIFICATES


     35.01.  Each party shall, at any time and from time to time, as requested
by the other party, upon not less than ten (10) days' prior notice, execute and
deliver to the requesting party a statement certifying that this Lease is
unmodified and in full force and effect (or if there have been modifications,
that the same is in full force and effect as modified and stating the
modifications), certifying the dates to which the Fixed Rent and Additional
Charges have been paid, stating whether or not, to the best knowledge of the
party giving the statement, the requesting party is in default in performance of
any of its obligations under this Lease, and, if so, specifying each such
default of which the party giving the statement shall have knowledge, and
stating whether or not, to the best knowledge of the party giving the statement,
any event has occurred which with the giving of notice or passage of time, or
both, would constitute such a default of the requesting party, and, if so,
specifying each such event; any such statement delivered pursuant hereto shall
be deemed a representation and warranty to be relied upon by the party
requesting the certificate and by others with whom such party may be dealing,
regardless of independent investigation.  Tenant also shall include in any such
statement such other information concerning this Lease as Landlord may
reasonably request.

                                       47
<PAGE>

                            ARTICLE 36 - ARBITRATION


     36.01.  Landlord may at any time request arbitration, and Tenant may at any
time when not in default in the payment of any Rent request arbitration, of any
matter in dispute but only where arbitration is expressly provided for in this
Lease. If Tenant desires to arbitrate any demand by Landlord for compliance with
any provision of this Lease, Tenant shall as a condition of Tenant's right to
require arbitration, comply with such demand during the pendency of such
arbitration proceeding.  The party requesting arbitration shall do so by giving
notice to that effect to the other party, specifying in said notice the nature
of the dispute, and said dispute shall be determined in Newark, New Jersey, in
accordance with the rules then obtaining of the American Arbitration Association
(or any comparable organization designated by Landlord).  The award in such
arbitration may be enforced on the application of either party by the order or
judgment of a court of competent jurisdiction.  The fees and expenses of any
arbitration shall be borne by the parties equally, but each party shall bear the
expense of its own attorneys and experts and the additional expenses of
presenting its own proof.  If Tenant gives notice requesting arbitration as
provided in this Article, Tenant shall simultaneously serve a duplicate of the
notice on each Superior Mortgagee and Superior Lessor whose name and address
shall previously have been furnished to Tenant, and such Superior Mortgagees and
Superior Lessor shall have the right to participate in such arbitration. In the
event such arbitration is with respect to a matter concerning a determination by
the Architect, such arbitration shall be conducted in accordance with the
construction industry rules of the American Arbitration Association on an
expedited bases (or their substantial equivalent, if such arbitration is
conducted by an alternative organization providing alternative dispute
resolution services).

                        ARTICLE 37 - MEMORANDUM OF LEASE


     37.01.  Tenant shall not record this Lease.  However, at the request of
Landlord or Tenant, each party shall promptly execute, acknowledge and deliver
to the other a memorandum of lease in respect of this Lease sufficient for
recording.  Such memorandum shall not be deemed to change or otherwise affect
any of the obligations or provisions of this Lease.  Whichever party records
such memorandum of Lease shall pay all recording costs and expenses, including
any taxes that are due upon such recording.

                       ARTICLE 38 - INTENTIONALLY OMITTED

                           ARTICLE 39 - MISCELLANEOUS


     39.01.  Tenant expressly acknowledges and agrees that Landlord has not made
and is not making, and Tenant, in executing and delivering this Lease, is not
relying upon, any warranties, representations, promises or statements, except to
the extent that the same are expressly set forth in this Lease or in any other
written agreement(s) which may be made between the parties concurrently with the
execution and delivery of this Lease.  All understandings and agreements
heretofore had between the parties are merged in this Lease and any other
written agreement(s) made concurrently herewith, which alone fully and
completely express the agreement of the parties and which are entered into after
full investigation.  Neither party has relied upon any statement or
representation not embodied in this Lease or in any other written agreement(s)
made concurrently herewith.  The submission of this Lease to Tenant does not
constitute by Landlord a reservation of, or an option to Tenant for, the Demised
Premises, or an offer to lease on the terms set forth herein and this Lease
shall become effective as a lease agreement only upon execution and delivery
thereof by Landlord and Tenant.

     39.02.  No agreement shall be effective to change, modify, waive, release,
discharge, terminate or effect an abandonment of this Lease, in whole or in
part, unless such agreement is in writing, refers expressly to this Lease and is
signed by the party against whom enforcement of the change, modification,
waiver, release, discharge, termination or effectuation of abandonment is
sought.

     39.03.  If Tenant shall at any time request Landlord to sublet or let the
Demised Premises for Tenant's account, Landlord or its agent is authorized to
receive keys for such purposes without releasing Tenant from any of its
obligations under this Lease, and Tenant hereby releases Landlord of any
liability for loss or damage to any of the Tenant's Property in connection with
such subletting or letting.

     39.04.  Except as otherwise expressly provided in this Lease, the
obligations under this Lease shall bind and benefit the successors and assigns
of the parties hereto with the same effect as if mentioned in each instance
where a party is named or referred to; provided, however, that (a) no violation
of the provisions of Article 11 shall operate to vest any rights in any
successor or assignee of Tenant and (b) the provisions of this Section 39.04
shall not be construed as modifying the conditions of limitation contained in
Article 27.

     39.05.  Except for Tenant's obligations to pay Rent, the time for Landlord
or Tenant, as the case may be, to perform any of its respective obligations
hereunder shall be extended if and to the extent that the performance thereof
shall be prevented due to any Unavoidable Delay (subject to the limits on
extensions for Unavoidable Delay expressly provided for in this Lease). The
extension shall be limited to the duration of the Unavoidable Delay measured
from the date notice thereof is given by one party to the other. Except as
expressly provided to the contrary, the obligations of Tenant hereunder shall
not be affected, impaired or excused, nor shall Landlord

                                       49
<PAGE>

have any liability whatsoever to Tenant, (a) because Landlord is unable to
fulfill, or is delayed in fulfilling, any of its obligations under this Lease
due to any of the matters set forth in the first sentence of this Section 39.05,
or (b) because of any failure or defect in the supply, quality or character of
electricity, water or any other utility or service furnished to the Demised
Premises for any reason beyond Landlord's reasonable control.

     39.06.  Any liability for payments hereunder (including, without
limitation, Additional Charges) shall survive the expiration of the Term or
earlier termination of this Lease.

     39.07.  If Tenant shall request Landlord's consent and Landlord shall fail
or refuse to give such consent, Tenant shall not be entitled to any damages for
any withholding by Landlord of its consent; Tenant's sole remedy shall be an
action for specific performance or injunction, and such remedy shall be
available only in those cases where Landlord has expressly agreed in writing not
to unreasonably withhold or delay its consent or where as a matter of law
Landlord may not unreasonably withhold its consent. Notwithstanding the
foregoing to the contrary, in the event Landlord wrongfully withholds its
consent to a proposed assignment or subletting, Tenant shall have the right to
pursue an action for its actual direct damages. In no event shall Landlord be
liable for any consequential or exemplary damages, or any damages in excess of
the Fixed Rent and Additional Charges (other than Tenant's share of the Excess
Amount) payable by Tenant for the period of such proposed sublease or
assignment.

     39.08.  If an excavation shall be made upon land adjacent to or under the
Building, or shall be authorized to be made, Tenant shall afford to the Person
causing or authorized to cause such excavation, license to enter the Demised
Premises for the purpose of performing such work as said Person shall reasonably
deem necessary or desirable to preserve and protect the Building from injury or
damage and to support the same by proper foundations, without any claim for
damages or liability against Landlord and without reducing or otherwise
affecting Tenant's obligations under this Lease.

     39.09.  Tenant shall not exercise its rights under Article 15 or any other
provision of this Lease in a manner which would violate Landlord's union
contracts or create any work stoppage, picketing, labor disruption or dispute or
any interference with the business of Landlord or any tenant or occupant of the
Building.

     39.10.  Tenant shall give prompt notice to Landlord of (a) any occurrence
in or about the Demised Premises for which Landlord might be liable, (b) any
fire or other casualty in the Demised Premises, (c) any damage to or defect in
the Demised Premises, including the fixtures and equipment thereof, for the
repair of which Landlord might be responsible, and (d) any damage to or defect
in any part of the Building's sanitary, electrical, heating, ventilating, air-
conditioning, elevator or other systems located in or passing through the
Demised Premises or any part thereof.

     39.11.  This Lease shall be governed by and construed in accordance with
the laws of the State of New Jersey.  Tenant hereby irrevocably agrees that any
legal action or proceeding arising

                                       50
<PAGE>

out of or relating to this Lease may be brought in the Courts of the State of
New Jersey, or the Federal District Court for the District of New Jersey, as
Landlord may elect. By execution and delivery of this Lease, Tenant hereby
irrevocably accepts and submits generally and unconditionally for itself and
with respect to its properties, to the jurisdiction of any such court in any
such action or proceeding, and hereby waives in the case of any such action or
proceeding brought in the courts of the State of New Jersey, or Federal District
Court for the District of New Jersey, any defenses based on jurisdiction, venue
or forum non conveniens. If any provision of this Lease shall be invalid or
unenforceable, the remainder of this Lease shall not be affected and shall be
enforced to the extent permitted by law. The table of contents, captions,
headings and titles in this Lease are solely for convenience of reference and
shall not affect its interpretation. This Lease shall be construed without
regard to any presumption or other rule requiring construction against the party
causing this Lease to be drafted. If any words or phrases in this Lease shall
have been stricken out or otherwise eliminated, whether or not any other words
or phrases have been added, this Lease shall be construed as if the words or
phrases so stricken out or otherwise eliminated were never included in this
Lease and no implication or inference shall be drawn from the fact that said
words or phrases were so stricken out or otherwise eliminated. Each covenant,
agreement, obligation or other provision of this Lease on Tenant's part to be
performed, shall be deemed and construed as a separate and independent covenant
of Tenant, not dependent on any other provision of this Lease. All terms and
words used in this Lease, regardless of the number or gender in which they are
used, shall be deemed to include any other number and any other gender as the
context may require. In the event Landlord permits Tenant to examine Landlord's
books and records with respect to any Additional Charge imposed under this
Lease, such examination shall be conducted at Tenant's sole cost and expense and
shall be conditioned upon Tenant performing such examination utilizing Tenant's
own employees or retaining an independent accounting firm for such purposes who
or which shall not be compensated on any type of contingent fee basis with
respect to such examination. Wherever in this Lease or by law Landlord or Tenant
is authorized to charge or recover costs and expenses for legal services or
attorneys' fees, same shall include, without limitation, the costs and expenses
for in-house or staff legal counsel or outside counsel at rates not to exceed
the reasonable and customary charges for any such services as would be imposed
in an arms length third party agreement for such services.

                                       51

     39.12.  Within thirty (30) days of each anniversary date of this Lease,
Tenant shall annually furnish to Landlord a copy of its then current audited

otherwise
without prior authorization of Tenant.

     IN WITNESS WHEREOF, Landlord and Tenant have duly executed this Lease as of
the day and year first above written.

RIDER TO LEASE AGREEMENT DATED MAY__, 1999 BETWEEN 90 HUDSON STREET L.L.C.
("LANDLORD") AND NATIONAL DISCOUNT BROKERS GROUP, INC. ("TENANT")
___________________________________________________________________________

     R1.  Rider Governs. If any of the provisions of this Rider shall conflict
          -------------
with any of the provisions, printed or typewritten, of this Lease, such conflict
shall be resolved in every instance in favor of the provisions of this Rider.

     R2.  Renewal Options.   Provided Tenant is not in default of its monetary
          ---------------
or material non-monetary obligations under this Lease beyond any applicable
notice and cure periods, Tenant, shall, subject to the provisions of sub-section
5 hereof, have two (2) options to extend the Term of its lease of the Demised
Premises, from the date upon which this Lease would otherwise expire for an
extended period of five (5) years (each herein referred to as an "Extended
Period", the first of which referred to as the "First Extended Period" and the
second referred to as the "Second Extended Period" respectively), upon the
following terms and conditions:

          1.  If Tenant elects to exercise any one or both of said options, it
     shall do so by giving notice of such election to Landlord on or before the
     date which is one (1) year before the beginning of the Extended Period for
     which the Term is to be extended by the exercise of such option.  Tenant
     agrees that it shall have forever waived its right to exercise any such
     option if it shall fail for any reason whatsoever to give such notice to
     Landlord by the time provided herein for the giving of such notice, whether
     such failure is inadvertent or intentional, time being of the essence as to
     the exercise of each such option.

          2.  If Tenant elects to exercise any one or both of said options, the
     Term shall be automatically extended for the Extended Period covered by the
     option so exercised without execution of an extension or renewal lease.
     Within ten (10) days after request of either party following the effective
     exercise of any such option, however, Landlord and Tenant shall execute,
     acknowledge and deliver to each other duplicate originals of an instrument
     in recordable form confirming that such option was effectively exercised.

          3.  Each Extended Period shall be upon the same terms and conditions
     as are in effect immediately preceding the commencement of such Extended
     Period; provided, however, that Tenant shall have no right or option to
     extend the Term for any period of time beyond the expiration of the Second
     Extended Period and, provided further, that in the Extended Period(s) the
     Fixed Rent shall be as follows:

          The Fixed Rent during the Extended Periods shall be at ninety-five
          percent (95%) of Fair Market Value ("FMV").  FMV shall be determined
          by mutual agreement of the parties.  If the parties are unable to
          agree on the FMV within thirty (30) days of Tenant's exercise of its
          option, the parties shall choose a licensed Real

                                       53
<PAGE>

          Estate Appraiser who shall determine the FMV. The cost of said Real
          Estate Appraiser shall be borne equally by the parties. If the parties
          are unable to agree on a licensed Real Estate Appraiser within forty-
          five (45) days of Tenant's exercise of its option, each party shall
          select one Appraiser to appraise the FMV. All appraisals shall be
          rendered within thirty (30) days of appointment of the respective
          Appraiser appointed under this paragraph. If the difference between
          the two appraisals is 20% or less of the lower appraisal, then the FMV
          shall be the average of the two appraisals. If the difference between
          the two appraisals is greater than 20% of the lower appraisal, the two
          Appraisers shall select a third licensed Real Estate Appraiser to
          appraise the FMV. The FMV shall in such case be the average of the
          three appraisals. The cost of the third appraisal shall be borne
          equally by the parties.

          Anything to the contrary contained herein notwithstanding, the Fixed
          Rent for the Extended Periods shall not be less than the Fixed Rent
          for the period immediately preceding the Extended Period for which the
          Fixed Rent is being calculated.

     4.  Any termination, expiration, cancellation or surrender of this Lease
shall terminate any right or option for the Extended Period(s) not yet
exercised.

     5.  If Tenant at any time during the Term (including, but not limited to
the First Extended Period has (other than to an Affiliate of Tenant) assigned
this Lease or sublet all or more than fifty percent (50%) of the Demised
Premises and is itself not in occupation and conducting business in at least one
half (1/2) of the Demised Premises in accordance with the terms of this Lease,
the renewal options granted pursuant to this Section R2 shall be limited to the
First Extended, if such sublease, assignment or failure to occupy occurs during
the original Term; and if such sublease, assignment, or failure to occupy occurs
during the First Extended Period; the Second Extended Period shall expire on the
date which is five (5) years after the date of such sublease or assignment.

     6.  The options provided herein to extend the Term of the Lease may not be
severed from the Lease or separately sold, assigned or otherwise transferred.

     R3.   Tenant Allowance.  Landlord agrees that provided this Lease is in
           ----------------
full force and effect, Landlord shall contribute the sum of Twenty-seven &00/100
Dollars ($27.00) multiplied by the Floor Space of the Demised Premises
(Landlord's Contribution) towards the cost of Tenant's Work and Tenant's
furniture, fixtures and equipment to be installed at the Demised Premises, and
the ancillary costs actually incurred by Tenant in connection with Tenant's
preparation of and move to the Demised Premises, including Tenant's moving
costs, and Tenant's architectural, engineering and filing fees (collectively,

     (A) Landlord's Contribution shall be paid monthly as work progress, in
proportion to the total work to be completed, subject to certification by
Tenant's architect (i) as to the

                                       54
<PAGE>

percentage completed and (ii) that the total amount of Tenant's Work completed
(inclusive of Tenant's Ancillary Costs) is estimated to be not less than Twenty-
seven &00/100 Dollars ($27.00) multiplied by the number of square feet of Floor
Space of the Demised Premises. At, Tenant's option, Landlord shall pay
Landlord's Contribution directly to Tenant's contractors, suppliers or
materialmen, as directed by Tenant.

     (B) Prior to and as a condition precedent to Landlord's obligation to make
such payments, Tenant shall deliver to Landlord:  (i) lien waivers executed by
Tenant's general contractor and all subcontractors, materialmen and suppliers,
such partial lien waivers to be accompanied by affidavits of Tenant's general
contractor setting forth the names of all such subcontractors, materialmen and
suppliers; (ii) an affidavit from the architect having supervision over Tenant's
Work, to the effect that such Tenant's Work has been performed in accordance
with the plans and specifications approved by Landlord and in compliance with
all Legal Requirements.

     (C) In addition to Landlord's Contribution Landlord agrees that provided
this Lease is in full force and effect, Landlord shall contribute the sum of
$156,948 (the "Raised Floor Allowance") to be applied to the cost of the
installation of an eight inch concrete filled raised floor by Tenant on the
portion of the Demised Premises located on the fifth floor of the Building on
the terms set forth below:  Landlord's Raised Floor Allowance shall be paid upon
lien free completion of such installation by Tenant as certified by Tenant's
architect. Prior to and as a condition precedent to Landlord's obligation to
make such payment, Tenant shall deliver to Landlord:  (i) lien waivers executed
by Tenant's general contractor and all subcontractors, materialmen and
suppliers, such partial lien waivers to be accompanied by affidavits of Tenant's
general contractor setting forth the names of all such subcontractors,
materialmen and suppliers; (ii) an affidavit from the architect having
supervision over Tenant's Work, to the effect that such installation has been
performed in accordance with the plans and specifications approved by Landlord
and in compliance with all Legal Requirements.

     (D) If Landlord defaults in the payment of Landlord's Contribution or the
Raised Floor Allowance, and such default is not cured within thirty (30) days
after notice, then Tenant shall have the right to recoup, by offsetting against
the next installment(s) of Fixed Rent and Additional Charges due hereunder, an
amount equal to any portion of the Landlord's Contribution or the Raised Floor
Allowance as to which Landlord is in default, together with interest at the rate
of ten percent (10%) per annum on any outstanding amount not so offset.

          ---------------------------------------------
reasonable efforts to cause the Tenant Possession Date to occur by June 1, 1999,
subject to delays caused by Tenant or its agents or contractors, or other

be postponed (but without duplication of any postponement or abatement otherwise
provided in this Lease as the result of late completion of Landlord's Work) by
one (1) day for each day of delay, in the event such delay is the cause of a
corresponding delay in Tenant's ability to obtain a certificate of occupancy for
the Demised Premises, for up to sixty (60) days of delay, and by two (2) days
for each day of delay thereafter, in the event such delay is the cause of a
corresponding delay in Tenant's ability to obtain a certificate of occupancy for

Tenant, to subordinate its rights to enforce its Landlord's Lien on Tenant's
furniture, fixtures and equipment to the extent they constitute Tenant's
Property under this Lease to the rights of Tenant's secured lender to enforce
its lien thereon, provided such lender is a banking institution or recognized
commercial lender, licensed or authorized to do business in New Jersey, is not a
Tenant Affiliate, and holds a perfected security interest in such Tenant's
Property  (herein a " Tenant's Lender").  Tenant's Lender shall have rights only
to Tenant's Property that can be removed without damage to the Demised Premises
or the Building.   Tenant's Lender may, upon prior written notice to Landlord,
remove such Tenant's Property from the Premises at any time while Tenant has
legal possession of the Demised Premises or within fifteen (15) days after
termination of this Lease, provided Tenant's Lender first pays Landlord all Rent
due under the Lease (as defined therein) for such period, time being of the
essence in connection with the preceding obligations of Tenant's Lender.
Tenant's Lender shall be responsible for paying the cost of repairing any damage
to the Demised Premises and the Building in which its collateral is located
resulting from the removal of any such Tenant's Property or the acts, omissions
or negligence of Tenant's Lender or its agents or representatives, and shall

subordination provided herein, Tenant's Lender shall indemnify and hold harmless
Landlord and its Superior Lessors and Superior

                                       61

Mortgagees against all loss, damage, costs, claims, suits, liabilities and
expenses, including but not limited to reasonable attorney's fees arising from
or in connection with the acts, omissions or negligence of Tenant's Lender or
its agents or representatives or the enforcement or claim of such lien. Prior to
removal of such Tenant's Property, Tenant's Lender shall provide Landlord with
appropriate proof of its security interest therein and entitlement thereto, as
well as proof of liability insurance in the amount of at least $5,000,000.00
covering such entry into the Premises and removal of Tenant's Property, and
shall name Landlord and, at Landlord's request, any Superior Lessors and
Superior Mortgagees as additional insureds. Nothing contained herein shall be
deemed to be an assignment of this Lease or a consent to an assignment of the
Lease.

         R15.  Mortgagee Approval.  Landlord shall use reasonable efforts to

Lease from the proposed Mortgagee having issued a loan commitment (i.e. Teachers

mortgage loan) all in accordance with the provisions of Article 9 hereof.
Tenant shall, upon execution of this Lease execute and deliver to Landlord
Superior Mortgage Non-Disturbance Agreements in the forms annexed hereto as
Exhibit H.  In the event said Mortgagees do not provide such agreements to
Tenant by the date which is fourteen (14) days after the date hereof (the
"Contingency Period"), Tenant shall have the right upon written notice to
Landlord given not later than the expiration of the initial Contingency Period
to either (i) terminate this Lease, or (ii) extend the Contingency Period for up
to sixty (60) days, or (iii) waive the contingency contained herein for
obtaining Non-Disturbance Agreements.  If Tenant does not exercise its right
under this Paragraph R15 to terminate this Lease by the expiration of the
Contingency Period, as the same may be extended, such termination right shall be
waived and be deemed null and void and of no further force or effect.  Landlord
agrees that it shall not offer the Demised Premises for lease to other
prospective tenants during the pendency of the Contingency Period, as the same
may be extended pursuant to this Paragraph R15.

         R16.  Recapture of Certain Grade Level Areas.  Landlord shall have the
               --------------------------------------

costs due to the operation of any HVAC by Tenant and for Landlord's costs in
connection with any standby steam fitter or electrician required as the result
of Tenant's usage thereof).

only to the minimum extent necessary.  For the purposes hereof  "Data Center"
shall mean that certain portion of the Demised Premises located on the sixth
floor containing Tenant's primary computer data facility, as more particularly
shown on Exhibit O hereto.

  (b) In the event that Tenant is denied access to or is unable to utilize (i)
the Data Center, or (ii) five (5%) percent or more of the Demised Premises, for
three (3) consecutive Business Days or more, by reason of the rights reserved to
Landlord under the sections identified in subsection (a) of this Paragraph R18,
then Rent shall be abated on the Demised Premises or the portions thereof to
which Tenant has been denied access or is unable to utilize until the earlier to

space.
