      For and in consideration of the covenants herein contained, and upon the
terms and conditions herein set forth, Lessor and Lessee agree as follows:

      1. DESCRIPTION. Lessor hereby leases to Lessee, and Lessee hereby hires
from Lessor, the Demised Premises as defined on the Reference Page (hereinafter
called "Demised Premises" or "Premises"), as shown on the plan or plans,
initialed by the parties hereto, marked Exhibit A attached hereto and made part
of this Lease in the Building as defined on the Reference Page (hereinafter
called the "Building") which is situated as part of that Complex of Buildings
known as 401, 407, 411 and 433 Hackensack Avenue, Hackensack, New Jersey, also
known as Continental Plaza (hereinafter called the "Complex"), all located on
that certain Parcel as defined on the Reference Page (hereinafter called the
"Parcel"), as described on Exhibit A-1, together with the right to use in common
with other lessees of the Building, their invitees, customers and employees,
those public areas of the Common Facilities as hereinafter defined.

      2. TERM. The Premises are leased for the Term to commence on the
Commencement Date, and to end at 12:00 midnight on the Expiration Date, all as
defined on the Reference Page.

      3. BASIC RENT. The Lessee shall pay to the Lessor during the Term, the
Term Fixed Basic Rent as defined on the Reference Page (hereinafter called the
"Term Fixed Basic Rent"), payable in such coin or currency of the United States
of America as at the time of payment shall be legal tender for the payment of
public and private debts. The Term Fixed Basic Rent shall accrue at the Annual
Fixed Basic Rent as defined on the Reference Page and shall be payable in
advance on the first day of each calendar month during the Term in installments
of Monthly Fixed Basic Rent as defined on the Reference Page, except that a
proportionately lesser sum may be paid for the first and last months of the Term
of this Lease if the Term commences on a day other than the first day of the
month, in accordance with the provisions of this Lease herein set forth. Lessor
acknowledges receipt from Lessee of the first installment of Monthly Fixed Basic
Rent for the Term, by check, subject to collection. Lessee shall pay Fixed Basic
Rent and any Additional Rent as hereinafter provided, to Lessor at Lessor's
above stated address, or at such other place as Lessor may designate in writing,
without demand and without counterclaim, deduction or setoff. The aforesaid
Fixed Basic Rent shall be subject to adjustment as in Section 24 provided. As
used in this Lease, Fixed Basic Rent shall mean either Term Fixed Basic Rent,
Annual Fixed Basic Rent or Monthly Fixed Basic Rent, as appropriate.

      4. USE, OCCUPANCY AND THE NON-VIOLATION OF LAW. Lessee shall use and
occupy the Premises for the Permitted Use as defined on the Reference Page and
for no other purpose. Notwithstanding anything to the contrary contained in this
Lease, Lessee, in the use and occupancy of the Premises and in the prosecution
and conduct of any business thereon, shall conform to all requirements of all
laws, orders, ordinances, rules and regulations of the Federal, State, county
and municipal authorities and with any direction or certificate of occupancy
issued pursuant to any law of or by any public officer or officers. Lessee
covenants that it will not use or permit to be used any part of the Premises for
any unlawful purpose or for any dangerous, noxious or offensive trade or
business and will not cause or maintain any nuisance in, at or on the Premises.


                                       3

      5. COMPLIANCE WITH LAW/CARE AND REPAIR OF PREMISES/ENVIRONMENTAL.

            A. Lessee covenants to commit no act of waste and to take good care
      of the Premises and the fixtures and appurtenances thereon, and shall, in
      the use and occupancy of the Premises, comply with all present and future
      laws, orders and regulations of the Federal, State and municipal
      governments or any of their departments affecting the Premises and with
      any and all environmental requirements resulting from the Lessee's use of
      the Premises; this covenant to survive the expiration or sooner
      termination of the Lease. Lessor shall, at Lessee's expense, make all
      necessary repairs to the Premises except where the need for said repair is
      due to the Lessor's acts or that of its agents or employees. Lessor shall
      make all necessary repairs to the Common Facilities and to the parking
      areas, if any, the same to be included as an Operating Cost pursuant to
      Section 25 herein, except where the repair has been made necessary by
      misuse or neglect by Lessee or Lessee's agents, servants, visitors or
      licensees, in which event Lessor shall nevertheless make the repair but
      Lessee shall pay to Lessor, as Additional Rent, immediately upon demand,
      the costs therefor (net of any insurance proceeds which Lessor may receive
      on account of such repair). If any repairs, alterations or improvements to
      the Demised Premises are necessary to comply with the aforesaid
      governmental rules and regulations, and said repairs or improvements are
      not required as a result of Lessee's specific manner of use, then Lessor
      shall make said repair and/or improvement, and the cost shall be included
      as an Operating Cost. The term "specific use" shall mean the manner in
      which Lessee uses the Premises in contradiction to the mere use by Lessee
      of the Premises as general offices. Lessor shall comply with all present
      and future laws, orders and regulations of the federal, state and
      municipal governments or any of their departments affecting the Common
      Facilities, the same to be included as an Operating Cost, except where the
      need for such compliance has been made necessary by the specific manner of
      Lessee's use, in which case Lessor shall effect the compliance but Lessee
      shall pay to Lessor, as Additional Rent, immediately upon demand, the
      costs thereof. All improvements made by Lessee to the Premises, which are
      so attached to the Premises that they cannot be removed without material
      injury to the Premises, shall become the property of Lessor upon
      installation. Not later than the last day of the Term, Lessee shall, at
      Lessee's expense, remove all Lessee's personal property and those
      improvements made by Lessee which have not become the property of Lessor,
      including trade fixtures (other than built-in cabinetwork), movable
      paneling partitions, electrical, telephone, computer and antenna wiring,
      cabling and related conduit, connection boxes, switches and outlets
      installed in the ceilings, floors and walls of the Demised Premises and
      the like; repair all injury done by or in connection with the installation
      or removal of said property, improvements, wiring and the like; cap or
      terminate all electrical and telephone connections at service entry panels
      as required by law; and surrender the Premises in as good condition as
      they were at the beginning of the Term, reasonable wear and damage by
      fire, the elements, casualty, or other cause not due to the misuse or
      neglect by Lessee, Lessee's agents, servants, visitors or licensees
      excepted. All other property of Lessee remaining on the Premises after the
      last day of the Term of this Lease shall be conclusively deemed abandoned
      and may be removed by Lessor, and Lessee shall reimburse Lessor for the
      cost of such removal. Lessor may have any such property stored at Lessee's
      risk and expense. Notwithstanding anything


                                       4
<Page>

      contained herein to the contrary, Lessee shall not be obligated to remove
      any of the initial installation described on Exhibit C attached hereto.

            B. Lessee acknowledges the existence of environmental laws, rules
      and regulations, including but not limited to the provisions of ISRA, as
      hereinafter defined. Lessee shall comply with any and all such laws, rules
      and regulations. Lessee represents to Lessor that Lessee's Standard
      Industrial Classification (SIC) Number as designated in the Standard
      Industrial Classifications Manual prepared by the office of Management and
      Budget in the Executive Office of the President of the United States will
      not subject the Demised Premises to ISRA applicability. Any change by
      Lessee to an operation with an SIC Number subject to ISRA shall require
      Lessor's written consent. Any such proposed change shall be sent in
      writing to Lessor sixty (60) days prior to the proposed change. Lessor, at
      its sole option, may deny consent.

            C. Lessee hereby agrees to execute such documents as Lessor
      reasonably deems necessary and to make such applications as Lessor
      reasonably requires to assure compliance with ISRA. Lessee shall bear all
      costs and expenses incurred by Lessor associated with any required ISRA
      compliance resulting from Lessee's use of the Demised Premises including
      but not limited to State agency fees, engineering fees, clean-up costs,
      filing fees and suretyship expenses. As used in this Lease, ISRA
      compliance shall include applications for determinations of
      nonapplicability by the appropriate governmental authority. The foregoing
      undertaking shall survive the termination or sooner expiration of the
      Lease and surrender of the Demised Premises and shall also survive sale,
      or lease or assignment of the Demised Premises by Lessor. Lessee agrees to
      indemnify and hold Lessor harmless from any violation of ISRA occasioned
      by Lessee's use of the Demised Premises. The Lessee shall immediately
      provide the Lessor with copies of all correspondence, reports, notices,
      orders, findings, declarations and other materials pertinent to the
      Lessee's compliance and the requirements of the New Jersey Department of
      Environmental Protection ("NJDEP") under ISRA as they are issued or
      received by the Lessee.

            D. Lessee agrees not to generate, store, manufacture, refine,
      transport, treat, dispose of, or otherwise permit to be present on or
      about the Demised Premises, any Hazardous Substances. As used herein,
      Hazardous Substances shall be defined as any "hazardous chemical,"
      "hazardous substance" or similar term as defined in the Comprehensive
      Environmental Responsibility Compensation and Liability Act, as amended
      (42 U.S.C. 9601, et seq.), the New Jersey Environmental Cleanup
      Responsibility Act, as amended, N.J.S.A. 13:1K-6 ET SEQ. and/or the
      Industrial Site Recovery Act ("ISRA"), the New Jersey Spill Compensation
      and Control Act, as amended, N.J.S.A. 58:10-23.11b, ET SEQ., any rules or
      regulations promulgated thereunder, or in any other applicable Federal,
      State or local law, rule or regulation dealing with environmental
      protection. It is understood and agreed that the provisions contained in
      this Section shall be applicable notwithstanding the fact that any
      substance shall not be deemed to be a Hazardous Substance at the time of
      its use by the Lessee but shall thereafter be deemed to be a Hazardous
      Substance.


                                       5
<Page>

            E. In the event Lessee fails to comply with ISRA as stated in this
      Section or any other governmental law as of the termination or sooner
      expiration of the Lease and as a consequence thereof Lessor is unable to
      rent the Demised Premises, then the Lessor shall treat the Lessee as one
      who has not removed at the end of its Term, and thereupon be entitled to
      all remedies against the Lessee provided by law in that situation
      including a monthly rental of two hundred (200%) percent of the
      installment of Monthly Fixed Basic Rent for the last month of the Term of
      this Lease or any renewal term, payable in advance on the first day of
      each month, until such time as Lessee provides Lessor with a negative
      declaration or confirmation that any required clean-up plan has been
      successfully completed.

            F. Lessee agrees that Lessee, its agents and contractors, licensees,
      or invitees shall not handle, use, manufacture, store or dispose of any
      Hazardous Substances on, under, or about the Premises, without Lessor's
      prior written consent (which consent may be given or withheld in Lessor's
      sole discretion), provided that Lessee may handle, store, use or dispose
      of products containing small quantities of Hazardous Substances, which
      products are of a type customarily found in offices and households (such
      as aerosol cans containing insecticides, toner for copies, paints, paint
      remover, and the like), and provided further that Lessee shall handle,
      store, use and dispose of any such Hazardous Substances in a safe and
      lawful manner and shall not allow such Hazardous Substances to contaminate
      the Premises or the environment.

            G. Without limiting the above, Lessee agrees to reimburse, defend,
      indemnify and hold harmless the Lessor and each mortgagee of the Demised
      Premises from and against any and all liabilities, damages, claims,
      losses, judgments, causes of action, costs and expenses, including without
      limitation, loss of rental income, loss due to business interruption, and
      the reasonable fees and expenses of counsel which may be incurred by the
      Lessor or any such mortgagee or threatened against .the Lessor or such
      mortgagee, arising out of or in any way connected with the use,
      manufacture, storage or disposal of Hazardous Substances by Lessee, its
      agents or contractors on, under or about the Premises including, without
      limitation, the costs of any required or necessary investigation, repair,
      cleanup or detoxification, and the preparation of any closure or other
      required plans in connection herewith, whether voluntary or compelled by
      governmental authority, or any breach by Lessee of the undertakings set
      forth in this Section. The indemnity obligations of Lessee under this
      clause shall survive any termination or expiration of the Lease.

            H. Notwithstanding anything set forth in this Lease, Lessee shall
      only be responsible for contamination of Hazardous Substances or any
      cleanup resulting directly therefrom, resulting directly from matters
      occurring or Hazardous Substances deposited (other than by contractors,
      agents or representatives controlled by Lessor) during the Lease Term, and
      any other period of time during which Lessee is in actual or constructive
      occupancy of the Premises. Lessee shall take reasonable precautions to
      prevent the contamination of the Premises with Hazardous Substances by
      third parties.

            I. It shall not be unreasonable for Lessor to withhold its consent
      to any proposed assignment or sublease if (i) the proposed assignee's or
      sublessee's anticipated


                                       6
<Page>

      use of the Premises involves the generation, storage, use, treatment or
      disposal of Hazardous Substances; (ii) the proposed assignee or sublessee
      has been required by any prior landlord, lender or governmental authority
      to take remedial action in connection with Hazardous Substances
      contaminating a property if the contamination resulted from such
      assignee's or sublessee's actions or use of the property in question; or
      (iii) the proposed assignee or sublessee is subject to an enforcement
      order issued by any governmental authority in connection with the use,
      disposal, or storage of a Hazardous Substance.

      6. ALTERATIONS, ADDITIONS OR IMPROVEMENTS. Lessee shall not, without first
obtaining the written consent of Lessor, make any alterations, additions or
improvements in, to or about the Premises which consent shall not be
unreasonably withheld, conditioned or delayed provided the requested alteration,
addition or improvement does not affect or impact the Building Structure, the
Building exterior or the Building mechanical, electrical or plumbing systems. As
used herein, "Building Structure" shall be the footings, foundation, the steel
supporting columns, exterior walls, and pipes leading from the Building line to
the street.

      7. ACTIVITIES INCREASING FIRE INSURANCE RATES. Lessee shall not do or
suffer anything to be done on the Premises which will increase the rate of fire
insurance on the Building.

      8. ASSIGNMENT AND SUBLEASE. Lessee may not mortgage, pledge, hypothecate,
assign, transfer, sublet or otherwise deal with this Lease or the Premises in
any manner except as specifically provided for in this Section 8:

            A. In the event that the Lessee desires to sublease or assign the
      Premises or sublease all or any portion of the Premises to any other
      party, the terms and conditions of such sublease or assignment and the
      identity of the sublessee or assignee, provided all by means of an
      executed agreement conditioned on Lessor's approval, shall be communicated
      to the Lessor in writing not less than twenty (20) days prior to the
      effective date of any such sublease or assignment, and, prior to such
      effective date, the Lessor shall have the option, exercisable in writing
      to the Lessee within ten (10) business days following Lessor's receipt of
      the above-referenced agreement, to, if an assignment, recapture the within
      Lease so that such prospective assignee shall then become the sole lessee
      of Lessor hereunder or, if a sublease, to recapture said space proposed to
      be sublet for its proposed duration and the within Lessee shall be fully
      released from any and all obligations hereunder as to said space for said
      proposed duration.

            B. In the event that the Lessor elects not to recapture the Lease or
      part thereof as the case may be in accordance with (A) above, the Lessee
      may nevertheless assign this Lease or sublet the whole or any portion of
      the Premises so offered to Lessor, subject to the Lessor's prior written
      consent, which consent shall not be unreasonably withheld, and subject to
      the consent of any mortgagee, trust deed holder or ground lessor, on the
      basis of the terms and conditions enumerated herein in this Subsection
      8(B). However, Lessor shall not be deemed unreasonable if it refuses to
      consent to any proposed sublease or an assignment of the Lease to a
      tenant, subtenant or other occupant of the Building or


                                       7
<Page>

      Complex (or to a subsidiary or affiliate), or if, in the reasonable
      judgment of Lessor, the business of such proposed subtenant or assignee is
      not compatible with the type of occupancy of the Building, violates any
      exclusive granted to any other tenant in the Building, or such business
      will create increased use of the Common Facilities of the Parcel and/or
      Building or if the proposed sublease or assignment is to any State,
      Federal or municipal agency or bureau.

                  (1) The Lessee shall provide to the Lessor the name and
            address of the assignee or sublessee, and copies of financial
            reports and other relevant financial information of the assignee or
            sublessee reasonably required by Lessor.

                  (2) The assignee shall assume, by written instrument, all of
            the obligations of this Lease, and a copy of such assumption
            agreement shall be furnished to the Lessor within ten (10) days of
            its execution. Any sublease shall be subject to the Lease and said
            sublessee shall expressly acknowledge that said sublessee's rights
            against the Lessor shall be no greater than those of the Lessee.

                  (3) The Lessee and each assignee shall be and remain liable
            for the observance of all the covenants and provisions of this
            Lease, including, but not limited to, the payment of Term Fixed
            Basic Rent and Additional Rent reserved herein as and when required
            to be paid, through the entire Term of this Lease, as the same may
            be renewed, extended or otherwise modified.

                  (4) The Lessee and any assignee shall promptly pay to Lessor
            any consideration received for any assignment or all of the rent
            (Fixed Basic and Additional), and any other consideration payable by
            the subtenant to Lessee under or in connection with the sublease
            (including, but not limited to, sums paid for the sale of Lessee's
            fixtures, leasehold improvements, equipment, furniture, or other
            personal property in excess of its depreciable book value or in
            excess of its fair rental value if said items are rented to the
            assignee or sublessee), as and when received, in excess of the Term
            Fixed Basic Rent and Additional Rent required to be paid by Lessee
            for the period affected by said assignment or sublease for the area
            sublet, computed on the basis of an average square foot rent for the
            gross square footage Lessee has leased and net of the reasonable
            costs incurred by Lessee in connection with any such sublet or
            assignment.

                  (5) In any event, the acceptance by the Lessor of any rent
            (Fixed Basic and Additional) from the assignee or from any of the
            subtenants or the failure of the Lessor to insist upon a strict
            performance of any of the terms, conditions and covenants herein
            shall not release the Lessee herein, nor any assignee assuming this
            Lease, from any and all of the obligations herein during and for the
            entire Term of this Lease.

                  (6) Lessor shall require a Five Hundred and 00/100 ($500.00)
            Dollar payment to cover its handling charges for each request for
            consent to any sublet or assignment prior to its consideration of
            the same, except that the aforesaid payment shall be waived once
            during the Term.


                                       8
<Page>

                  (7) Lessee shall have no claim, and hereby waives the right to
            any claim, against Lessor for money damages by reason of any
            refusal, withholding or delaying by Lessor of any consent, and in
            such event, Lessee's only remedies therefor shall be an action for
            specific performance, injunction or declaratory judgment to enforce
            any such requirement.

            C. Any sublet or assignment to an "Affiliate" as hereinafter defined
      shall not be subject to the provisions of Subsections 8(A), 8(B)(4) or
      8(B)(6) hereof and shall not require Lessor's prior written consent, but
      all other provisions of this Section shall, apply.

            D. In the event that any or all of Lessee's interest in the Premises
      and/or this Lease is transferred by operation of law to any trustee,
      receiver, or other representative or agent of Lessee, or to Lessee as a
      debtor in possession, and subsequently any or all of Lessee's interest in
      the Premises and/or this Lease is offered or to be offered by Lessee or
      any trustee, receiver, or other representative or agent of Lessee as to
      its estate or property (such person, firm or entity being hereinafter
      referred to as the "Grantor"), for assignment, conveyance, lease, or other
      disposition to a person, firm or entity other than Lessor (each such
      transaction being hereinafter referred to as a "Disposition"), it is
      agreed that Lessor has and shall have a right of first refusal to
      purchase, take, or otherwise acquire, the same upon the same terms and
      conditions as the Grantor thereof shall accept upon such Disposition to
      such other person, firm, or entity; and as to each such Disposition the
      Grantor shall give written notice to Lessor in reasonable detail of all of
      the terms and conditions of such Disposition within twenty (20) days next
      following its determination to accept the same but prior to accepting the
      same, and Grantor shall not make the Disposition until and unless Lessor
      has failed or refused to accept such right of first refusal as to the
      Disposition, as set forth herein.

            Lessor shall have sixty (60) days next following its receipt of
      the written notice as to such Disposition in which to exercise the
      option to acquire Lessee's interest by such Disposition, and the
      exercise of the option by Lessor shall be effected by notice to that
      effect sent to the Grantor; but nothing herein shall require Lessor to
      accept a particular Disposition or any Disposition, nor does the
      rejection of any one such offer of first refusal constitute a waiver or
      release of the obligation of the Grantor to submit other offers
      hereunder to Lessor. In the event Lessor accepts such offer of first
      refusal, the transaction shall be consummated pursuant to the terms and
      conditions of the Disposition described in the notice to Lessor. In the
      event Lessor rejects such offer of first refusal, Grantor may
      consummate the Disposition with such other person, firm, or entity; but
      any decrease in price of more than two (2%) percent of the price sought
      from Lessor or any change in the terms of payment for such Disposition
      shall constitute a new transaction requiring a further option of first
      refusal to be given to Lessor hereunder.

            E. Without limiting any of the provisions of Sections 13 and 14, if
      pursuant to the Federal Bankruptcy Code (or any similar law hereafter
      enacted having the same general purpose), or if pursuant to any State
      insolvency or bankruptcy law, Lessee 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 or law shall be deemed to mean the deposit of cash security in
      an amount equal to the sum of one (1) year's Annual Fixed Basic Rent and
      Additional Rent for the next


                                       9
<Page>

      succeeding twelve (12) months (which Additional Rent shall be reasonably
      estimated by Lessor), which deposit shall be held by Lessor for the
      balance of the Term, without interest, as Additional Security Deposit, as
      hereinafter defined, for the full performance of all of Lessee's
      obligations under this Lease, to be held and applied in the manner
      specified for the Security Deposit in Section 17 hereof.

            F. The sale or transfer of stock control, if Lessee be a
      corporation, shall be deemed an assignment of this Lease unless: (a) it
      involves the sale or issuance of securities registered under the
      Securities Act of 1933, as amended, (b) it is made amongst the existing
      stockholders of Lessee, (c) it results from the death of a stockholder of
      Lessee, or (d) it is in connection with a sale of all or substantially all
      of Lessee's assets. Additionally, the sale or transfer of stock control in
      connection with private financing by Lessee for its business shall not be
      deemed an assignment of this Lease if to (i) a company whose securities
      are registered under the Securities Act of 1933, as amended, or (ii) an
      investor or lender whose members have not been convicted of a criminal
      offense provided the existing shareholders of Lessee, or their survivors,
      continue to maintain an ownership interest with voting rights in Lessee.

            G. Except as specifically set forth above, no portion of the Demised
      Premises or of Lessee's interest in this Lease may be acquired by any
      other person or entity, whether by assignment, mortgage, sublease,
      transfer, operation of law or act of the Lessee, nor shall Lessee pledge
      its interest in this Lease or in any Security Deposit required hereunder.

            H. Subject to the provisions of Subsection 8(F) above, if Lessee is
      a corporation other than a corporation whose stock is listed and traded on
      a nationally recognized stock exchange, the provisions of this Subsection
      8(H) shall apply to a transfer (however accomplished, whether in a single
      transaction or in a series of related or unrelated transactions) of stock
      [or any other mechanism such as, by way of example, the issuance of
      additional stock, a stock voting agreement or change in class(es) of
      stock] which results in a change of control of Lessee as if such transfer
      of stock (or other mechanism) which results in a change of control of
      Lessee were an assignment of this Lease, and if Lessee is a partnership or
      joint venture, said provisions shall apply with respect to a transfer (by
      one or more transfers) of an interest in the distributions of profits and
      losses of such partnership or joint venture (or other mechanism, such as,
      by way of example, the creation of additional general partnership or
      limited partnership interests) which results in a change of control of
      such a partnership or joint venture as if such transfer of an interest in
      the distributions of profits and losses of such partnership or joint
      venture which results in a change of control of such partnership or joint
      venture were an assignment of this Lease; but said provisions shall not
      apply to transactions with a corporation into or with which Lessee is
      merged or consolidated or to which all or substantially all of Lessee's
      assets are transferred or to any corporation which controls or is
      controlled by Lessee or is under common control with Lessee, provided that
      in the event of such merger, consolidation or transfer of all or
      substantially all of Lessee's assets, (i) the successor to Lessee has a
      net worth computed in accordance with generally accepted accounting
      principles at least equal to the greater of (a) the net worth of Lessee
      immediately prior to such merger, consolidation or transfer or (b) the net
      worth of Lessee


                                       10
<Page>

      herein named on the date of this Lease, and (ii) proof satisfactory to
      Lessor of such net worth shall have been delivered to Lessor at least ten
      (10) days prior to the effective date of any such transaction.

      9. COMPLIANCE WITH RULES AND REGULATIONS. Lessee shall observe and comply
with the Rules and Regulations hereinafter set forth in Exhibit B attached
hereto and made a part hereof and with such further reasonable Rules and
Regulations as Lessor may prescribe, on notice to the Lessee, for the safety,
care and cleanliness of the Building and the comfort, quiet and convenience of
other occupants of the Building. Lessor shall enforce any such Rules and
Regulations in a non-discriminatory manner.

      10. DAMAGES TO BUILDING. If the Building is damaged by fire or any other
cause to such extent that the cost of restoration, as reasonably estimated by
Lessor, will equal or exceed twenty-five (25%) percent of the replacement value
of the Building (exclusive of foundations) just prior to the occurrence of the
damage, then Lessor may, no later than the sixtieth (60th) day following the
damage, give Lessee a notice of election to terminate this Lease, or if the cost
of restoration will equal or exceed fifty (50%) percent of such replacement
value and if the Premises shall not be reasonably usable for the purpose for
which they are leased hereunder, then Lessee may, no later than the sixtieth
(60th) day following the damage, give Lessor a notice of election to terminate
this Lease. In either said event of election, this Lease shall be deemed to
terminate on the thirtieth (30th) day after the giving of said notice, and
Lessee shall surrender possession of the Premises within a reasonable time
thereafter; and the Term Fixed Basic Rent and any Additional Rent shall be
apportioned as of the date of said surrender, and any Term Fixed Basic Rent or
Additional Rent paid for any period beyond the latter of the thirtieth (30th)
day after said notice, or the date Lessee surrenders possession, shall be repaid
to Lessee. If the cost of restoration shall not entitle Lessor to terminate this
Lease or if, despite the cost, Lessor does not elect to terminate this Lease,
Lessor shall restore the Building and the Premises with reasonable promptness,
subject to Force Majeure, as hereinafter defined, and except as stated above,
Lessee shall have no right to terminate this Lease. Lessor need not restore
fixtures and improvements owned by Lessee.

      Except as provided in Section 5 hereof, notwithstanding the provisions of
this Section or any other provision of this Lease, Lessor shall not have any
obligation whatsoever to repair, reconstruct, or restore the Premises when the
damages resulting from any casualty covered by the provisions of this Section
occur during the last twelve (12) months of the Term or any extension thereof,
and if Lessor elects not to restore the Premises pursuant to this sentence, this
Lease shall terminate and Lessee shall be released of any obligations thereafter
accruing.

      In any case in which use of the Premises is affected by any damage to the
Building, there shall be either an abatement or an equitable reduction in Term
Fixed Basic Rent and an equitable reduction in the Base Period Costs as
established in Section 25 depending on the period for which and the extent to
which the Premises are not reasonably usable for the purpose for which they are
leased hereunder. The words "restoration" and "restore" as used in this Section
10 shall include repairs. If the damage results from the fault of the Lessee, or
Lessee's agents, servants, visitors or licensees, Lessee shall not be entitled
to any abatement or reduction in Term Fixed Basic Rent or Additional Rent,
except to the extent of any rent insurance received by Lessor.


                                       11
<Page>

      11. WAIVER OF SUBROGATION. Except as provided in Section hereof,
notwithstanding the provisions of this Section or any other provision of this
Lease, in the event of any loss or damage to the Building, the Premises and/or
any contents (herein "property damage"), each party waives all claims against
the other for any such loss or damage and each party shall look only to any
insurance which it has obtained to protect against such loss (or in the case of
Lessee, waives all claims against any tenant of the Building that has similarly
waived claims against such Lessee), and each party shall obtain, for each policy
of such insurance, provisions waiving any claim against the other party [and
against any other tenant(s) in the Building that has waived subrogation against
the Lessee] for loss or damage within the scope of such insurance.

      12. EMINENT DOMAIN. If Lessee's use of the Premises is materially affected
due to the taking by eminent domain of (a) the Premises or any part thereof or
any estate therein; or (b) any other part of the Building; then, in either
event, this Lease shall terminate on the date when title vests pursuant to such
taking. The Term Fixed Basic Rent and any Additional Rent shall be apportioned
as of said termination date and any Term Fixed Basic Rent or Additional Rent
paid for any period beyond said date shall be repaid to Lessee. Lessee shall not
be entitled to any part of the award for such taking or any payment in lieu
thereof, but Lessee may file a separate claim for any taking of fixtures and
improvements owned by Lessee which have not become the Lessor's property, and
for moving expenses, provided the same shall in no way affect or diminish
Lessor's award. In the event of a partial taking which does not effect a
termination of this Lease but does deprive Lessee of the use of a portion of the
Demised Premises, there shall either be an abatement or an equitable reduction
of the Term Fixed Basic Rent, and an equitable adjustment reducing the Base
Period Costs depending on the period for which and the extent to which the
Premises so taken are not reasonably usable for the purpose for which they are
leased hereunder.

      13. INSOLVENCY OF LESSEE. Either (a) the appointment of a receiver to take
possession of all or substantially all of the assets of Lessee, or the filing of
any bankruptcy or insolvency proceeding consented to or acquiesced in by Lessee
or, if involuntary, not stayed or dismissed within sixty (60) days, or (b) a
general assignment by Lessee for the benefit of creditors, or (c) any action
taken or suffered by Lessee under any insolvency or bankruptcy act, shall
constitute a default of this Lease by Lessee, and Lessor may terminate this
Lease forthwith and upon notice of such termination Lessee's right to possession
of the Demised Premises shall cease, and Lessee shall then quit and surrender
the Premises to Lessor but Lessee shall remain liable as hereinafter, provided
in Section 14 hereof.

      14. LESSOR'S REMEDIES ON DEFAULT. If Lessee defaults in the payment of
Term Fixed Basic Rent or any Additional Rent, or defaults in the performance of
any of the other covenants and conditions hereof or permits the Premises to
become deserted, abandoned or vacated, Lessor may give Lessee notice of such
default, and if Lessee does not cure any Term Fixed Basic Rent or Additional
Rent default within five (5) days of the giving of such notice or other default
within fifteen (15) days after giving of such notice [or if such other default
is of such nature that it cannot be completely cured within such period, if
Lessee does not commence such curing within such fifteen (15) days and
thereafter proceed with reasonable diligence and in good faith to cure such
default], then Lessor may terminate this Lease on not less than ten (10) days'
notice to Lessee unless, prior to Lessor's ten (10) day notice to Lessee, Lessee
shall have


                                       12
<Page>

cured said default, and on the date specified in said notice, Lessee's right to
possession of the Demised Premises shall cease, and Lessee shall then quit and
surrender the Premises to Lessor, but Lessee shall remain liable as hereinafter
provided. If this Lease shall have been so terminated by Lessor pursuant to
Sections 13 or 14 hereof, Lessor may at any time thereafter resume possession of
the Premises by any lawful means and remove Lessee or other occupants and their
effects.

      15. DEFICIENCY. In any case where Lessor has recovered possession of the
Premises by reason of Lessee's default, Lessor may, at Lessor's option, occupy
the Premises or cause the Premises to be redecorated, altered, divided,
consolidated with other adjoining premises, or otherwise changed or prepared for
reletting, and may relet the Premises or any part thereof as agent of Lessee or
otherwise, for a term or terms to expire prior to, at the same time as, or
subsequent to, the original expiration date of this Lease, at Lessor's option,
and receive Term Fixed Basic Rent and Additional Rent therefor. Term Fixed Basic
Rent or Additional Rent so received shall be applied first to the payment of
such expenses as Lessor may have incurred in connection with the recovery of
possession, redecorating, altering, dividing, consolidating with other adjoining
premises, or otherwise changing or preparing for reletting, and the reletting,
including brokerage and reasonable attorney's fees, and then to the payment of
damages in amounts equal to the Term Fixed Basic Rent and Additional Rent
hereunder and to the costs and expenses of performance of the other covenants of
Lessee as herein provided. Lessee agrees, in any such case, whether or not
Lessor has relet, to pay to Lessor damages equal to the Term Fixed Basic Rent
and Additional Rent and other sums herein agreed to be paid by Lessee, as and
when due, less the net proceeds of the reletting, if any, as ascertained from
time to time, as of the due date, and the same shall be payable by Lessee on the
several rent days above specified. Lessee shall not be entitled to any surplus
accruing as a result of any such reletting, nor shall any surplus be applied to
offset the damages referred to in the preceding sentence. In reletting the
Premises as aforesaid, Lessor may grant rent concessions consistent with the
then market practice, and Lessee shall not be credited therewith. No such
reletting shall constitute a surrender and acceptance or be deemed evidence
thereof. If Lessor elects, pursuant hereto, actually to occupy and use the
Premises or any part thereof during any part of the balance of the Term as
originally fixed or since extended, there shall be allowed against Lessee's
obligation for Term Fixed Basic Rent and Additional Rent or damages as herein
defined, during the period of Lessor's occupancy, the reasonable value of such
occupancy, not to exceed in any event the Term Fixed Basic Rent and Additional
Rent herein reserved and such occupancy shall not be construed as a release of
Lessee's liability hereunder. Alternatively, in any case where Lessor has
recovered possession of the Premises by reason of Lessee's default, Lessor may
at Lessor's option, and at any time thereafter, and without notice or other
action by Lessor, and without prejudice to any other rights or remedies it might
have hereunder or at law or equity, become entitled to recover from Lessee, as
damages for such breach, in addition to such other sums herein agreed to be paid
by Lessee, to the date of re-entry, expiration and/or dispossess, an amount
equal to the difference between the Term Fixed Basic Rent and the Additional
Rent reserved in this Lease from the date of such default to the date of
expiration of the original Term demised and the then fair and reasonable rental
value (inclusive of Additional Rent and Term Fixed Basic Rent) of the Premises
for the same period. Said damages shall become due and payable to Lessor
immediately upon such breach of this Lease and without regard to whether this
Lease be terminated or not, and if this Lease is terminated, without regard to
the manner in which it is terminated. In the computation of such damages, the
difference between any installments of rent


                                       13
<Page>

(Fixed Basic and Additional) thereafter becoming due, and fair and reasonable
rental value of the Premises (inclusive of the same rent components) for the
period for which such installment was payable shall be discounted to the date of
such default at the rate of not more than four (4%) percent per annum.

      Lessee hereby waives all right of redemption to which Lessee or any
person under Lessee might be entitled by any law now or hereafter in force.
In addition, in the event of a default which results in the Lessor recovering
possession of the Premises, Lessor shall be under a duty to mitigate Lessor's
damages to the extent required by law and then only if Lessor does not have
comparable space available for lease within the Complex.

      Lessor's remedies hereunder are in addition to any remedy allowed by
law.

      Lessee agrees to pay, as Additional Rent, all attorney's fees and other
expenses incurred by the Lessor in enforcing any of the obligations under
this Lease, this covenant to survive the expiration or sooner termination of
this Lease.

      16. SUBORDINATION OF LEASE. This Lease and any option contained herein
shall, at Lessor's option, or at the option of any holder of any underlying
lease or holder of any first mortgage or first deed of trust, be subject and
subordinate to any such underlying leases and to any such first mortgage and/or
first trust deed which may now or hereafter affect the real property of which
the Premises form a part, and also to all renewals, modifications,
consolidations and replacements of said underlying leases and said first
mortgage and first trust deed. Although no instrument or act on the part of
Lessee shall be necessary to effectuate such subordination, Lessee will,
nevertheless, execute and deliver such further instruments confirming such
subordination of this Lease as may be desired by the holders of said first
mortgage and first trust deed or by any of the lessors under such underlying
leases. If any underlying lease to which this Lease is subject terminates,
Lessee shall, on timely request, attorn to the owner of the reversion. Lessor
agrees to request, on behalf of Lessee, a nondisturbance agreement from the
holder of any of the aforesaid underlying leases or first mortgages or first
trust deeds in the form attached hereto as Exhibit D; however, this Lease is not
conditioned upon the same being granted, and any charges assessed by the holders
of such aforesaid underlying leases or first mortgages or first trust deeds in
connection with the obtaining of the aforesaid nondisturbance agreement shall be
paid by Lessee. Notwithstanding anything contained herein to the contrary, this
Lease shall only be subordinate to first mortgages or trust deeds first placed
of record subsequent to the date of this Lease provided the holders thereof
agree not to disturb Lessee's possession if Lessee is not in default under this
Lease and provided Lessee agrees to attorn to said holder.

      17. SECURITY DEPOSIT. In the event of the insolvency of Lessee, or in the
event of the entry of a judgment in bankruptcy in any court against Lessee which
is not discharged within thirty (30) days after entry, or in the event a
petition is filed by or against Lessee under any chapter of the bankruptcy laws
of the State of New Jersey or the United States of America, then, in such event,
Lessor may require the Lessee to deposit security in the amount specified in
Subsection 8(E) to adequately assure Lessee's performance of all of its
obligations under this Lease including all payments subsequently accruing.
Failure of Lessee to deposit the Security Deposit required by this Section
within ten (10) days after Lessor's written demand shall constitute a material
breach of this Lease by Lessee.

      In the event any security is required to be deposited pursuant to the
terms of this Lease and in the event Lessor uses any of said security deposit to
cure Lessee's default(s) or meet any of Lessee's obligations, Lessee covenants
to upon demand replace the amount so utilized. In the


                                       14
<Page>

event of a bona fide sale, subject to this Lease, Lessor shall have the right to
transfer the Security Deposit to the vendee for the benefit of Lessee, and
Lessor shall be considered released by Lessee from all liability for the return
of such security; and Lessee agrees to look solely to the new lessor for the
return of the said Security Deposit, and it is agreed that this shall apply to
every transfer or assignment made of the Security Deposit to a new lessor. The
security deposited as provided for herein shall not be mortgaged, assigned or
encumbered by Lessee without the written consent of Lessor.

      18. RIGHT TO CURE LESSEE'S BREACH. If Lessee breaches any covenant or
condition of this Lease, Lessor may, on reasonable notice to Lessee (except that
no notice need be given in case of emergency), cure such breach at the expense
of Lessee and the reasonable amount of all expenses, including attorneys' fees,
incurred by Lessor in so doing inclusive of a reasonable charge for any in-house
counsel shall be deemed Additional Rent payable on demand, with interest at two
(2%) percent per annum over the prime lending rate announced as such by Chase
Manhattan Bank to its most creditworthy customers or the highest rate permitted
by law, whichever is lower.

      19. LIENS. Lessee shall not do any act, or make any contract, which may
create or be the foundation for any lien or other encumbrance upon any interest
of Lessor or any ground or underlying lessor in any portion of the Premises. If,
because of any act or omission (or alleged act or omission) of Lessee, any
Construction Lien Claim or other lien (collectively "Lien"), charge, or order
for the payment of money or other encumbrance shall be filed against Lessor
and/or any ground or underlying lessor and/or any portion of the Premises
(whether or not such Lien, charge, order, or encumbrance is valid or enforceable
as such), Lessee shall, at its own cost and expense, cause same to be discharged
of record or bonded within fifteen (15) days after the filing thereof; and
Lessee shall indemnify and save harmless Lessor and all ground and underlying
lessor(s) against and from all costs, liabilities, suits, penalties, claims, and
demands, including reasonable counsel fees, resulting therefrom. If Lessee fails
to comply with the foregoing provisions, Lessor shall have the option of
discharging or bonding any such Lien, charge, order, or encumbrance, and Lessee
agrees to reimburse Lessor for all costs, expenses and other sums of money in
connection therewith (as additional rental) with interest at the maximum rate
permitted by law promptly upon demand. All materialmen, contractors, artisans,
mechanics, laborers, and any other persons now or hereafter contracting with
Lessee or any contractor or subcontractor of Lessee for the furnishing of any
labor services, materials, supplies, or equipment with respect to any portion of
the Premises, at any time from the date hereof until the end of the Lease Term,
are hereby charged with notice that they look exclusively to Lessee to obtain
payment for same.

      20. RIGHT TO INSPECT AND REPAIR. Lessor may enter the Premises but shall
not be obligated to do so (except as required by any specific provision of this
Lease) at any reasonable time on reasonable notice to Lessee (except that no
notice need be given in case of emergency) for the purpose of inspection or the
making of such repairs, replacement or additions, in, to, on and about the
Premises or the Building, as Lessor deems necessary or desirable. During the
last twelve (12) months of the Term, Lessor may immediately enter, alter,
renovate or redecorate the Premises if Lessee shall have removed all or
substantially all of Lessee's property from the Premises. Such actions by Lessor
shall have no effect on this Lease or Lessee's obligations hereunder, and Lessee
shall have no claims or cause of action against


                                       15
<Page>

Lessor by reason thereof, but Lessor agrees, to the extent reasonably possible,
to not unreasonably interfere with, Lessee's use of the Premises, or to
unnecessarily store tools or materials within the Premises or to materially
reduce Lessee's floor space.

      21. SERVICES TO BE PROVIDED BY LESSOR. Subject to intervening laws,
ordinances, regulations and executive orders, while Lessee is not in default
under any of the provisions of this Lease, Lessor agrees to furnish, on
"Business Days," as hereinafter defined:

            A. Janitorial services to be performed in accordance with Building
      standards and practices, to include restroom supplies.

            B. Heating, ventilating and air conditioning (herein "HVAC"), as
      appropriate for the season, together with Common Facilities lighting and
      electric energy all during "Building Hours," as hereinafter defined.

            C. Cold and hot water for drinking and lavatory purposes.

            D. Elevator service including freight elevator service during
      Building Hours.

            E. Notwithstanding any other provision of this Lease, Lessor shall
      not be liable for failure to furnish any of the aforesaid services when
      such failure is due to Force Majeure, as hereinafter defined.

      22. AFTER-HOURS USE. Lessee shall be entitled to make use of HVAC beyond
Building Hours, at Lessee's sole cost and expense, provided Lessee shall notify
the Lessor twenty-four (24) hours prior to such desired overtime use, except if
such use is desired for a weekend, in which event Lessee shall notify Lessor no
later than 5:00 p.m. on the Thursday immediately preceding said weekend. It is
understood and agreed that Lessee shall pay the sum of Eighty-five and 00/100
($85.00) Dollars per hour, plus such additional percentage increase of the
aforesaid hourly sum computed by measuring the percentage increase of the rate
in effect (including fuel surcharges or adjustments) during the month for which
such overtime use is requested against the Base Utility Rate, as defined on the
Reference Page, with appropriate proportionate allocation among other Building
tenants within the zone servicing Lessee who also request overtime service
during the same period.

      In no event shall the Lessee pay less than the sum of Eighty-five and
00/100 ($85.00) Dollars per hour for such aforesaid overtime use.

      23. INTERRUPTION OF SERVICES OR USE. Interruption or curtailment of any
service maintained in the Building or the Complex or at the Parcel, if caused by
Force Majeure, as hereinafter defined, shall not entitle Lessee to any claim
against Lessor or to any abatement in Term Fixed Basic Rent or Additional Rent,
and shall not constitute a constructive or partial eviction, unless Lessor fails
to take measures as may be reasonable under the circumstances to restore the
service. If Lessor fails to take such measures as may be reasonable under the
circumstances to restore the curtailed service, Lessee's remedies shall be
limited to an equitable abatement of Term Fixed Basic Rent and Additional Rent
for the duration of the curtailment beyond said reasonable period, to the extent
such Premises are not reasonably usable by Lessee or to a claim of constructive
eviction. If the Premises are rendered untenantable in whole or in


                                       16
<Page>

part, for a period of ten (10) consecutive business days, by the making of
repairs, replacements or additions, other than those made with Lessee's consent
or caused by misuse or neglect by Lessee, or Lessee's agents, servants, visitors
or licensees, there shall be a proportionate abatement of Term Fixed Basic Rent
and Additional Rent from and after said tenth (10th) consecutive business day
and continuing for the period of such untenantability. In no event shall Lessee
be entitled to claim a constructive eviction from the Premises unless Lessee
shall first have notified Lessor in writing of the condition or conditions
giving rise thereto, and, if the complaints be justified, unless Lessor shall
have failed, within a reasonable time after receipt of such notice, to remedy,
or commence and proceed with due diligence to remedy, such condition or
conditions, all subject to Force Majeure, as hereinafter defined. The remedies
provided for in this Section 23 shall be Lessee's sole remedies for any
interruption of services or use as described above.

      24. ELECTRICITY.

            A. Lessor, subject to the provisions of this Section 24, shall
      furnish electrical energy to or for the use of Lessee in the Premises in
      accordance with this Section 24.

            B. Throughout the Term, Lessor shall redistribute electrical energy
      to the Premises during Building Hours upon the following terms and
      conditions: (i) Lessee shall pay for such electrical energy as provided by
      this Section 24; (ii) Lessor will redistribute electricity to Lessee
      through presently installed electrical facilities for Lessee's reasonable
      use of normal office equipment and such lighting, electrical appliances
      and equipment as Lessor may permit to be installed in the Premises, all
      consistent with that wiring capacity that has been installed in the
      Premises; (iii) Lessee agrees that an independent electrical engineering
      consultant selected by Lessor shall from time to time make a survey of the
      electric power demand of the electric lighting fixtures and the electric
      equipment of Lessee used in the Premises to determine the average monthly
      electric consumption thereof, said survey to be at Lessee's expense.
      Lessor reserves the right to estimate Lessee's electric consumption until
      such a survey is made. The estimate will be based on One and 25/100
      ($1.25) Dollars per square foot per year of the rentable area of the
      Premises and Lessee agrees that the Annual Fixed Basic Rent, as defined on
      the Reference Page, has been increased to compensate Lessor for supplying
      Lessee with electric current by an estimated Electric Rent Inclusion
      Factor as defined on the Reference Page. The aforesaid survey shall take
      into account, among other things, any special electrical requirements of
      Lessee and use by Lessee of electrical energy at times other than during
      Building Hours on Business Days. The findings of such engineering
      consultant as to the proper Electric Rent Inclusion Factor based on such
      average monthly electric consumption shall, unless objected to by Lessee
      within ten (10) days of its receipt by Lessee, be conclusive and binding
      upon the parties and the amount thereof, less the Electric Rent Inclusion
      Factor, if in excess of the Electric Rent Inclusion Factor, shall be added
      to the Annual Fixed Basic Rent which shall be payable in installments of
      Monthly Fixed Basic Rent, payable for each month from the Commencement
      Date or if the amount thereof shall be lower than the Electric Rent
      Inclusion Factor, the difference therein shall be subtracted from the
      Annual Fixed Basic Rent and the resulting sum shall be the revised Annual
      Fixed Basic Rent which shall be payable in installments of Monthly Fixed
      Basic Rent (except that if the amount of such rent increase or decrease


                                       17
<Page>

      shall not have been determined on the Commencement Date, then, upon such
      subsequent determination, Lessee shall pay or receive a credit, as the
      case may be, for the retroactive determination from the Commencement Date
      to the date of such determination); (iv) If the Electric Rates (as
      hereinafter defined) on which the initial determination of said consultant
      was based shall be increased or decreased, then the Annual Fixed Basic
      Rent shall be increased or decreased in the amount equal to the change in
      Lessor's cost of supplying electrical current to the Premises resulting
      from such rate change, retroactive if necessary to the date of such
      increase or decrease in such Electric Rates. The Term Fixed Basic Rent, as
      defined on the Reference Page, shall be deemed modified accordingly by any
      of the aforesaid modifications. If Lessee objects to said findings of said
      independent engineering consultant within the aforesaid period and
      designates an independent engineering consultant of its own who shall be
      paid for by Lessee, the two consultants will, within the next ten (10)
      business days, seek to resolve any differences and if, within said ten
      (10) business day period they are unable to do so, they shall, within two
      (2) business days, designate a mutually acceptable electrical engineer
      whose decision, absent manifest error, shall be final and binding. If,
      within said two (2) business day period, Lessor's consultant and Lessee's
      consultant cannot agree on an independent third electrical engineering
      consultant acceptable to both whose decision shall be final and binding,
      either party may request the American Arbitration Association in Somerset,
      New Jersey to appoint such independent third electrical engineering
      consultant, whose decision shall be final and binding (the "AAA
      Consultant"). The cost of the AAA Consultant shall be assessed to the
      party whose position is at greatest variance from the finding of the AAA
      Consultant.

            C. Lessee shall make no material alterations or additions to the
      electric equipment appliances without first obtaining written consent from
      Lessor in each instance. If Lessee installs additional or substituted
      electrical equipment or appliances or otherwise increases its use of
      current, then the Electric Rent Inclusion Factor shall be redetermined by
      Lessor's electrical engineer or consultant, at Lessee's expense, and such
      determination shall be conclusive and binding upon Lessor and Lessee
      unless Lessee objects in the manner provided for in Subsection 24 (B)
      above in which case the dispute shall be resolved as provided for in said
      subsection. Lessee may at any time it believes any change in its
      electrical equipment or appliances or fixtures has reduced its electrical
      consumption request a resurvey of the Premises by Lessor's electrical
      engineer or consultant, at Lessee's expense. Any change in the Electric
      Rent Inclusion Factor resulting from a change in Lessee's consumption
      shall be effective as of the date of such change, and the Term Fixed Basic
      Rent enumerated herein shall be deemed modified accordingly, retroactive
      if necessary.

            D. Lessor shall not be liable in any way to Lessee for any loss,
      damage or expense which Lessee may sustain or incur as a result of any
      failure, defect or change in the quantity or character of electrical
      energy available for redistribution to the Premises pursuant to this
      Section nor for any interruption in the supply (except to the extent said
      interruption results from Lessor's nonpayment of electrical bills), and
      Lessee agrees that such supply may be interrupted for inspection, repairs
      and replacement and in emergencies. In any event, the full measure of
      Lessor's liability for any interruption in the supply due to Lessor's acts
      or omissions shall be an abatement of Term Fixed Basic


                                       18
<Page>

      Rent and Additional Rent. In no event shall Lessor be liable for any
      business interruption suffered by Lessee. Lessee covenants and agrees that
      at all times its use of electric current shall never exceed the capacity
      of existing feeders to the Building or the risers or wiring installation.
      Any riser or risers to supply Lessee's electrical requirements, upon
      written request of Lessee, shall be installed by Lessor, at the sole cost
      and expense of Lessee, if, in Lessor's sole judgment, the same are
      necessary and will not cause or create a dangerous or hazardous condition
      or entail excessive or unreasonable alterations, repairs or expense or
      interfere with or disturb other tenants or occupants. In addition to the
      installation of such riser or risers, Lessor shall also, at the sole cost
      and expense of Lessee, install all other equipment proper and necessary in
      connection therewith subject to the aforesaid terms and conditions.

            E. Provided Lessee is able to obtain service from a utility
      servicing the Building, Lessor reserves the right to terminate the
      redistribution of electricity to the Premises at any time, upon thirty
      (30) days' written notice to Lessee, in which event Lessee may make
      application directly to the utility company servicing the Building for
      Lessee's entire separate supply of electricity. Lessor, upon the
      expiration of the aforesaid thirty (30) day period, may discontinue
      furnishing the electric current, in which latter event Lessee's Annual
      Fixed Basic Rent shall be decreased by the charge for Electric Rent
      Inclusion Factor as of the date of discontinuance of the supplying of
      electric current, but this Lease shall otherwise remain in full force and
      effect. The term "Electric Rates" shall be deemed to mean the rates for
      the comparable usage charged by the public utility company furnishing
      electrical energy to the Building, including but not limited to any
      charges or surcharges incurred or taxes payable by Lessor in connection
      therewith or increase or decrease thereof by reason of fuel adjustment or
      any substitutions for such Electric Rates or additions thereto.

            F. If Lessor discontinues the furnishing of electricity, as provided
      in this Section 24, then, and in such event, Lessor shall permit Lessee to
      receive electrical service directly from the public utility supplying
      electrical service to the Building and shall permit the existing feeders,
      risers, wiring and other electrical facilities serving the Premises to be
      used by Lessee for such purpose to the extent that they are available,
      suitable and safe. If Lessor discontinues the furnishing of electricity
      due to actions of the utility company, Lessee shall, at its own expense,
      install any necessary electrical meter equipment, panel boards, feeders,
      risers, wiring and other conductor and equipment which may be required to
      obtain electrical energy directly from the public utility supplying the
      same. otherwise, if Lessor discontinues the furnishing of electricity,
      Lessor, at its own expense, shall install such items. Lessor shall have no
      liability whatsoever to Lessee by reason of Lessor's discontinuance of
      electrical service.

            G. Lessor, at Lessee's expense, shall furnish and install all lamps
      (including incandescent and fluorescent), starters and ballasts used in
      the Premises.

            H. Following a determination of an increase or decrease in the
      Electric Rent Inclusion Factor attributable to the furnishing of
      electrical energy to the Premises by Lessor as set forth in this Section
      24, Lessor and Lessee shall, upon request of either party, execute,
      acknowledge and deliver to each other a supplemental agreement in form


                                       19
<Page>

      satisfactory to Lessor reflecting such change in the Annual Fixed Basic
      Rent and Monthly Installment of Term Fixed Basic Rent, but any such change
      shall be effective whether or not such agreement is entered into.

            I. In addition to payments of the Electric Rent Inclusion Factor, if
      Lessee makes use of electric current on non-Business Days or after
      Building Hours, then Lessee shall pay to Lessor, as Additional Rent,
      Lessor's cost of supplying electrical current to the Premises at all such
      times when electrical current is so used. Such charge shall be made on a
      per hour (or any portion thereof) basis determined by the hourly cost of
      supplying electrical current to the Premises or such portions of the
      Building as must be supplied to provide electric current to the Premises;
      provided, however, that Lessee shall not be required under this Section to
      pay for use of electrical current which shall have previously been
      included in a survey of Lessee's use of electrical current pursuant to
      Subsection 24 (B) above.

            J. Notwithstanding anything contained herein to the contrary, Lessor
      reserves the right; at Lessor's cost and expense, to install a separate
      meter to measure electrical consumption to the Premises for lighting and
      equipment purposes, in which event Lessee shall pay the meter charges
      based upon the Electric Rates for said consumption in lieu of the amount
      determined pursuant to Subsection 24 (B) hereof, in which event Lessee's
      Annual Fixed Basic Rent shall be decreased by the charge for Electric Rent
      Inclusion Factor as of the date of installation of the meter.

      25. ADDITIONAL RENT. It is expressly agreed that Lessee will pay in
addition to the Term Fixed Basic Rent provided in Section 3 above, an Additional
Rent to cover Lessee's Percentage, as defined on the Reference Page, of the
increased cost to Lessor, for each of the categories enumerated herein, over the
"Base Period Costs," as defined on the Reference Page, for said categories.

            A. OPERATING COST ESCALATION. If during the Lease Term the Operating
Costs incurred for the Building in which the Demised Premises are located,
Complex and Parcel, for any Lease Year or proportionate part thereof if the
Lease Term expires prior to the expiration of a Lease Year (herein the
"Comparison Period") shall be greater than the Base Operating Costs (adjusted
proportionately if the Comparison Period is less than a Lease Year), then Lessee
shall pay to Lessor, as Additional Rent, Lessee's Percentage of all such excess
Operating Costs. Operating Costs shall include, by way of illustration and not
of limitation: personal property taxes; management fees; labor for Building
managers and staff, including all wages and salaries; social security taxes, and
other taxes which may be levied against Lessor upon such wages and salaries;
employee benefits and payroll taxes; accounting and legal fees; any sales, use
or service taxes incurred in connection with the operation of the Complex or
Parcel; supplies; repairs and maintenance; maintenance and service contracts;
the cost of security and alarm services; license permits and inspection fees;
painting of Common Facilities; wall and window washing; laundry and towel
service; tools and equipment (which are not required to be capitalized for
Federal income tax purposes); fire and other insurance; the cost of any loss
which is the responsibility of Lessor because of the existence of commercially
reasonable deductibles; trash removal; lawn care; snow removal and all other
items properly constituting direct operating costs according to standard
accounting practices (hereinafter collectively referred to as the "Operating
Costs").


                                       20
<Page>

Lessor shall be entitled to amortize and include in operating Costs an allocable
portion of the cost of capital improvement items (excluding any such
improvements made for a specific tenant's benefit), including life safety
systems, which are reasonably calculated to reduce operating expenses or which
are required under any governmental laws, regulations or ordinances which were
not applicable to the Building or Complex or Parcel at the time it was
constructed. All such costs shall be amortized over the reasonable life of such
improvements with interest at two (2%) percent over the prime lending rate
announced as such by Chase Manhattan Bank to its most creditworthy borrowers on
the unamortized amount in accordance with such reasonable life and amortization
schedules as shall be determined by Lessor in accordance with generally accepted
accounting principles. As used in this Subsection 25(A), the Base Period Costs
for Operating Costs shall be as defined on the Reference Page.

            B. FUEL, UTILITIES AND ELECTRIC COST ESCALATION. If during the Lease
Term the utility and energy costs, including any fuel surcharges or adjustments
with respect thereto, incurred for water, sewer, other utilities and heating,
ventilating and air conditioning for the Building, Complex and Parcel to include
all leased and leasable areas (not separately billed or metered within the
Building) and Common Facilities electric, lighting, water, sewer and other
utilities for the Building, the Complex and Parcel (hereinafter "Utility and
Energy Costs") for any Comparison Period shall be greater than the Base Utility
and Energy Costs (adjusted proportionately if the Comparison Period is less than
a Lease Year), then Lessee shall pay to Lessor as Additional Rent, Lessee's
Percentage of all such excess Utility and Energy Costs. Common Facilities
electric consumption shall be charged at the bulk rate at which Lessor purchases
electrical energy from the public utility supplying electrical service to the
Building. As used in this Subsection 25(B), the Base Utility and Energy Costs
shall be as defined on the Reference Page.

            C. TAX ESCALATION. If during the Lease Term the Real Estate Taxes
for the Building, the Complex and Parcel at which the Demised Premises are
located for any Comparison Period shall be greater than the Base Real Estate
Taxes (adjusted proportionately if the Comparison Period is less than a Lease
Year), then Lessee shall pay to Lessor as Additional Rent, Lessee's Percentage
of all such excess Real Estate Taxes.

      As used in this Subsection 25(C), the words and terms which follow mean
and include the following:

                  (i) The Base Period Costs for "Real Estate Taxes" shall be as
            defined on the Reference Page.

                  (ii) "Real Estate Taxes" shall mean the property taxes and
            assessments imposed upon the Building, the Complex and Parcel, or
            upon the Term Fixed Basic Rent and Additional Rent, as such, payable
            by the Lessor including, but not limited to, real estate, city,
            county, village, school and transit taxes, or taxes, assessments or
            charges levied, imposed or assessed against the Building and Complex
            by any other taxing authority, whether general or specific, ordinary
            or extraordinary, foreseen or unforeseen. If due to a future change
            in the method of taxation, any franchise, income or profit tax shall
            be levied against Lessor in substitution for, or in lieu of, or in
            addition to, any tax which would otherwise


                                       21
<Page>

            constitute a Real Estate Tax, such franchise, income or profit tax
            shall be deemed to be a Real Estate Tax for the purposes hereof;
            conversely, any additional real estate tax hereafter imposed in
            substitution for, or in lieu of, any franchise, income or profit tax
            (which is not in substitution for, or in lieu of, or in addition to,
            a Real Estate Tax as hereinbefore provided) shall not be deemed a
            Real Estate Tax for the purposes hereof. Notwithstanding anything
            contained herein to the contrary, Lessee shall assume and pay to
            Lessor in full at the time of paying the Term Fixed Basic Rent, any
            excise, sales, use, gross receipts or other taxes(other than a net
            income or excess profits tax) which may be imposed on or measured by
            such Term Fixed Basic Rent or Additional Rent or may be imposed on
            Lessor or on account of the letting or which Lessor may be required
            to pay or collect under any law now in effect or hereafter enacted.

            D. LEASE YEAR. As used in this Lease, Lease Year shall mean the
twelve (12) month period commencing on the Commencement Date and each twelve
(12) month period thereafter. Once the base costs are established, in the event
any lease period is less than twelve (12) months, then the Base Period Costs for
the categories listed above shall be adjusted to equal the proportion that said
period bears to twelve (12) months, and Lessee shall pay to Lessor as Additional
Rent for such period, an amount equal to Lessee's Percentage of the excess for
said period over the adjusted base with respect to each of the aforesaid
categories. Notwithstanding anything contained herein to the contrary, once the
base costs are established, Lessor reserves the right to calendarize billing and
payment in order to establish operating consistency.

            E. PAYMENT. At any time, and from time to time, after the
establishment of the Base Period Costs for each of the categories referred to
above, Lessor shall advise the Lessee in writing of Lessee's Percentage, as
defined on the Reference Page, with respect to each of the categories as
estimated for the current Lease Year [and for each succeeding Lease Year or
proportionate part thereof if the last period prior to the Lease's termination
is less than twelve (12) months] as then known to the Lessor, and thereafter,
the Lessee shall pay as Additional Rent, Lessee's Percentage of the excess of
these costs over the Base Period Costs for the then current period affected by
such advice (as the same may be periodically revised by Lessor as additional
costs are incurred) in equal monthly installments on the first day of each
month, such new rates being applied to any months for which the installments of
Monthly Fixed Basic Rent shall have already been paid which are affected by the
Operating Cost Escalation and/or Utility and Energy Cost Escalation and/or Tax
Escalation Costs above referred to, as well as the unexpired months of the
current period the adjustment for the then expired months to be made at the
payment of the next succeeding installment of Monthly Fixed Basic Rent, all
subject to final adjustment at the expiration of each Lease Year as defined in
Subsection 25 (D) hereof [or proportionate part thereof, if the last period
prior to the Lease's termination is less than twelve (12) months]. In the event
the last period prior to the Lease's termination is less than twelve (12)
months, the Base Period Costs during said period shall be proportionately
reduced to correspond to the duration of said final period.

            F. BOOKS AND RECORDS. For the protection of Lessee, Lessor shall
maintain books of account which shall be open to Lessee and its representatives
at all reasonable times so that Lessee can determine that such Operating,
Utility, Energy and Tax Costs have, in fact, been paid or incurred. Any
disagreement with respect to any one or more of said charges if not


                                       22
<Page>

satisfactorily settled between Lessor and Lessee shall be referred by either
party to an independent certified public accountant to be mutually agreed upon,
and if such an accountant cannot be agreed upon, the American Arbitration
Association may be asked by either party to select an arbitrator, whose decision
on the dispute will be final and binding upon both parties, who shall jointly
share any cost of such arbitration. Pending resolution of said dispute, the
Lessee shall pay to Lessor the sum so billed by Lessor subject to its ultimate
resolution as aforesaid.

            G. RIGHT OF REVIEW. Once Lessor shall have finally determined said
Operating, Utility and Energy or Tax Costs at the expiration of a Lease Year,
then, as to the item so established, Lessee shall only be entitled to dispute
said charge as finally established for a period of six (6) months after such
charge is finally established, and Lessee specifically waives any right to
dispute any such charge at the expiration of said six (6) month period.

            H. OCCUPANCY ADJUSTMENT. If, with respect to Operating Cost
Escalation, as established in Subsection 25(A) hereof, and Utility and Energy
Cost Escalation, as established in Subsection 25 (B) hereof, the Building is not
ninety-five (95%) percent occupied during the establishment of the respective
Base Period Costs, then the Base Period Costs incurred with respect to said
Operating Cost or Utility and Energy Cost shall be adjusted during any such
period so as to reflect ninety-five (95%) percent occupancy. Similarly, if,
during any Lease Year or proportionate part thereof subsequent to the
establishment of the respective Base Period Costs the Building is less than
ninety-five (95%) percent occupied, then the actual costs incurred for Operating
Cost and Utility and Energy Cost shall be increased during any such period to
reflect ninety-five (95%) percent occupancy so that at all times after the
establishment of the aforesaid Base Period Costs, the Utility and Energy Cost
and Operating Cost shall be actual costs, but in the event less than ninety-five
(95%) percent of the Building is occupied during all or part of the Lease Year
involved, the Utility and Energy Cost and Operating Cost shall not be less than
that which would have been incurred had ninety-five (95%) percent of the
Building been occupied. The aforesaid adjustment shall only be made with respect
to those items that are in fact affected by variations in occupancy levels. To
the extent any Operating Cost or Utility and Energy Cost is separately billed or
metered or paid for directly by any Building tenant, to include but not be
limited to Lessee, or for which Lessor receives reimbursements, said space shall
be considered vacant space for purposes of the aforesaid adjustment.

      26. LESSEE'S/LESSOR'S ESTOPPEL.

            A. Lessee or Lessor shall, from time to time, within ten (10) days
      of said other party's written request, execute, acknowledge and deliver to
      the party requesting the same a written statement certifying that the
      Lease is unmodified and in full force and effect, or that the Lease is in
      full force and effect as modified and listing the instruments of
      modification; the dates to which the Monthly Fixed Basic Rent and
      Additional Rent and charges have been paid; and, to the best of the
      party's knowledge, whether or not said other party is in default
      thereunder, and if so, specifying the nature of the default; and any other
      information which said requesting party shall reasonably request. It is
      intended that any such statement delivered pursuant to this Section 26 may
      be relied on by a prospective purchaser of Lessor's interest or mortgagee
      of Lessor's interest or assignee of any mortgage of Lessor's interest or
      assignee of Lessee's interest or purchaser of Lessee


                                       23
<Page>

      or prospective lender of Lessee. The party who has failed to deliver said
      estoppel hereby irrevocably appoints the other party or, in the case of
      Lessor if Lessor is a trust, Lessor's beneficiary or agent, as
      attorney-in-fact for the said party who has failed to deliver the
      estoppel, with full powers and authority to execute and deliver in the
      name of the party failing to deliver the estoppel such estoppel
      certificate if said party fails to deliver the same within such ten (10)
      day period and such certificate as signed by the requesting party or in
      the case of Lessor if Lessor is a trust, Lessor's beneficiary or agent, as
      the case may be, shall be fully binding on the party failing to deliver
      the estoppel, if said party fails to deliver a contrary certificate within
      five (5) days after receipt by said party of a copy of the certificate
      executed by the requesting party or in the case of Lessor if Lessor is a
      trust, Lessor's beneficiary or agent, as the case may be.

            B. Lessee's or Lessor's failure to deliver such statement within
      such time shall be conclusive upon the other party that: (i) this Lease is
      in full force and effect and not modified except as said party requesting
      such statement may represent; (ii) not more than one (1) installment of
      Monthly Fixed Basic Rent has been paid in advance; and (iii) there are no
      such defaults. Notwithstanding the presumptions of this Section, said
      party to whom a request for a statement has been made shall not be
      relieved of its obligation to deliver said statement.

      27. HOLDOVER TENANCY. If Lessee holds possession of the Premises after the
Term of this Lease, Lessee, at Lessor's option, shall become a tenant from month
to month under the provisions herein provided, but at a Monthly Fixed Basic Rent
as provided for pursuant to N.J.S.A. 2A:42-6 and without the requirement for
demand or notice by Lessor to Lessee demanding delivery of possession of said
Premises (but Additional Rent shall continue as provided in this Lease), which
sum shall be payable in advance on the first day of each month, and such tenancy
shall continue until terminated by Lessor by notice to Lessee given at least
thirty (30) days prior to the intended date of termination, or until Lessee
shall have given to Lessor, at least sixty (60) days prior to the intended date
of termination, a written notice of intent to terminate such tenancy, which
termination date must be as of the end of a calendar month. Lessee shall pay
Term Fixed Basic Rent and Additional Rent until such alterations and corrections
as are required to be made by Lessee are made, and until such additions and
improvements as Lessee is entitled to remove have been removed. Lessee shall
also pay all damages sustained by Lessor from any loss or liability resulting
from such holding over and delay in surrender. The time limitations described in
this Section 27 shall not be subject to extension for Force Majeure.

      28. RIGHT TO SHOW PREMISES. Lessor may show the Premises to prospective
purchasers and mortgagees; and, during the twelve (12) months prior to
termination of this Lease, to prospective tenants, during Building Hours on
reasonable notice to Lessee.

      29. LESSOR'S WORK - LESSEE'S DRAWINGS.

            A. Lessor agrees that prior to the commencement of the Term of this
      Lease, it will do substantially all of the work in the Demised Premises in
      accordance with Exhibit C attached hereto and made a part hereof and, in
      addition thereto, shall have laid the floor covering or an alternative
      thereto as specified in Exhibit C. All of said Exhibit C work,


                                       24
<Page>

      whether paid for in whole or in part by Lessee, is and shall remain the
      Lessor's property. Lessor shall contribute the sum of Sixty-seven Thousand
      and 00/100 ($67,000.00) Dollars towards the cost of the Exhibit C work and
      Lessee shall pay all sums in excess of Sixty-seven Thousand and 00/100
      ($67,000.00) Dollars promptly upon receipt of Lessor's invoice therefor.
      Lessee shall, upon execution of this Lease, deliver an unconditional
      evergreen irrevocable letter of credit having as its expiration date a
      date no earlier than six (6) months after the Term's Anticipated
      Expiration Date, drawn on a New York money center bank to Lessor's benefit
      and assignable without fee by Lessor in the principal amount of
      Sixty-seven Thousand and 00/100 ($67,000.00) Dollars. Said letter of
      credit may, if Lessor certifies in writing that as of the Operable Date
      (as hereinafter defined), Lessee is not in default under any of the
      provisions of this Lease, be reduced by Thirteen Thousand Four Hundred and
      00/100 ($13,400.00) Dollars. The Operable Date shall be the first (1st)
      anniversary of the Commencement Date and each anniversary thereafter. At
      the expiration date of this Lease, the letter of credit shall, if Lessee
      is not in default, be returned to Lessee. If Lessee shall be in default
      under any provision of this Lease beyond any notice or grace period,
      Lessor shall be entitled to negotiate said letter of credit and apply the
      proceeds against any damages to which it may be entitled pursuant to this
      Lease. Lessee acknowledges and agrees that it shall pay, upon Lessor's
      demand as Additional Rent under the Lease, any and all costs or fees
      charged in connection with the letter of credit that arise due to:(i)
      Lessor's sale or transfer of all or a portion of the Building or Complex;
      or (ii) the addition, deletion, or modification of any beneficiaries under
      the letter of credit.

            B. Lessee will timely supply such drawings and information to Lessor
      as set forth in Exhibit C. Any delay occasioned by Lessee's failure to
      timely supply such drawings and information shall not delay the
      Commencement Date of the Term, as hereinafter defined, and Lessee's
      obligations hereunder and the Commencement Date shall be the date the
      Premises would have been delivered to Lessee pursuant to Section 2, but
      for Lessee's delay.

            C. Lease Commencement shall occur and the Commencement Date is
      defined as that date when Lessor has done substantially all of the work to
      be done by Lessor in accordance with Exhibit C unless Lessor has been
      precluded from completing said work as a result of Lessee's acts or
      omissions including but not limited to its failure to comply with (B)
      above. Occupancy by Lessee or the delivery of a Certificate of Occupancy
      (temporary or permanent) by Lessor (if required pursuant to local law), so
      long as the floor covering has been installed, shall be prima facie
      evidence that Lessor has done substantially all of the work. Lessor shall
      complete any incomplete items existing as of the Commencement Date within
      a reasonable time thereafter.

      30. WAIVER OF TRIAL BY JURY. To the extent such waiver is permitted by
law, the parties waive trial by jury in any action or proceeding brought in
connection with this Lease or the Premises.

      31. LATE CHARGE. Lessee recognizes that late payment of any Term Fixed
Basic Rent or Additional Rent or other sum due hereunder will result in
administrative expense to Lessor, the extent of which additional expense is
extremely difficult and economically


                                       25
<Page>

impractical to ascertain. Lessee therefore agrees that if Monthly Fixed Basic
Rent or Additional Rent or any other sum is due and payable pursuant to this
Lease, and such amount remains due and unpaid ten (10) days after said amount is
due, such amount shall be increased by a late charge in an amount equal to the
greater of: (a) Fifty and 00/100 ($50.00) Dollars; or (b) a sum equal to five
(5%) percent of the unpaid monthly Fixed Basic Rent or Additional Rent or other
payment. The amount of the late charge to be paid by Lessee shall be reassessed
and added to Lessee's obligation for each successive monthly period until paid.
The provisions of this Section 31 in no way relieve Lessee of the obligation to
pay Term Fixed Basic Rent or Additional Rent or other payment on or before the
date on which they are due nor do the terms of this Section 31 in any way affect
Lessor's remedies pursuant to Section 14 in the event said Term Fixed Basic Rent
or Additional Rent or other payment is unpaid after date due.

      32. INSURANCE.

            A. LESSEE'S INSURANCE.

                  (1) Lessee covenants and represents, said representation being
            specifically designed to induce Lessor to execute this Lease, that
            during the entire Term hereof, at its sole cost and expense, Lessee
            shall obtain, maintain and keep in full force and effect the
            following insurance:

                        (a) "All Risk" property insurance against fire, theft,
                  vandalism, malicious mischief, sprinkler, leakage and such
                  additional perils as are now, or hereafter may be, included in
                  a standard extended coverage endorsement from time to time in
                  general use in the State of New Jersey upon property of every
                  description and kind owned by Lessee or under Lessee's care,
                  custody or control and located in the Building, Complex or
                  Parcel or for which Lessee is legally liable or installed by
                  or on behalf of Lessee, including by way of example and not by
                  way of limitation, furniture, fixtures, fittings,
                  installations and any other personal property (including the
                  work done by Lessor in connection with Exhibit C) in an amount
                  equal to the full replacement cost thereof.

                        (b) Commercial General Liability Insurance coverage to
                  include personal injury, bodily injury, broad form property
                  damage, operations hazard, owner's protective coverage,
                  contractual liability, products and completed operations
                  liability naming Lessor and Lessor's mortgagee or trust deed
                  holder and ground lessors (if any) as additional named
                  insureds in limits of not less than One Million and 00/100
                  ($1,000,000.00) Dollars.

                        (c) Business interruption insurance in such amounts as
                  will reimburse Lessee for direct or indirect loss of earnings
                  attributable to all perils commonly insured against by prudent
                  tenants or assumed by Lessee pursuant to this Lease or
                  attributable to prevention or denial of access to the
                  Premises, Building, Complex or Parcel as a result of such
                  perils.


                                       26
<Page>

                        (d) Workers' Compensation insurance in form and amount
                  as required by law.

                        (e) Business auto liability covering owned, non-owned
                  and hired vehicles with a limit of not less than One Million
                  and 00/100 ($1,000,000.00) Dollars per accident.

                        (f) Any other form or forms of insurance or any increase
                  in the limits of any of the aforesaid enumerated coverages or
                  other forms of insurance as Lessor or the mortgagees or ground
                  lessors (if any) of Lessor may reasonably require from time to
                  time if in the reasonable opinion of Lessor or said mortgagees
                  or ground lessors said coverage and/or limits become
                  inadequate or less than that commonly maintained by prudent
                  tenants in similar buildings in the area by tenants making
                  similar uses.

                  (2) All insurance policies required pursuant to this Section
            32 shall be taken out with insurers rated at least A+XV by A.M. Best
            Company, Oldwick, New Jersey, who are licensed to do business in the
            State and shall be in form satisfactory from time to time to Lessor.
            A policy or certificate evidencing such insurance together with a
            paid bill shall be delivered to Lessor not less than fifteen (15)
            days prior to the commencement of the Term hereof. Such insurance
            policy or certificate will provide an undertaking by the insurers to
            notify Lessor and the mortgagees or ground lessors (if any) of
            Lessor in writing not less than thirty (30) days prior to any
            material change, reduction in coverage, cancellation, or other
            termination thereof. Should a certificate of insurance initially be
            provided a policy shall be furnished by Lessee within thirty (30)
            days of the Term's commencement. The aforesaid insurance shall be
            written with no deductible.

                  (3) In the event of damage to or destruction of the Building
            and/or Premises entitling Lessor or Lessee to terminate this Lease
            pursuant to Section hereof, and if this Lease be so terminated,
            Lessee will immediately pay to Lessor all of its insurance proceeds,
            if any, relating to the leasehold improvements and alterations (but
            not Lessee's trade fixtures, equipment, furniture or other personal
            property of Lessee in the Premises) which have become Lessor's
            property on installation or would have become Lessor's property at
            the Term's expiration or sooner termination. If the termination of
            the Lease, at Lessor's election, is due to damage to the Building,
            and if the Premises have not been so damaged, Lessee will deliver to
            Lessor, in accordance with the provisions of this Lease, the
            improvements and alterations to the Premises which have become on
            installation or would have become at the Term's expiration, Lessor's
            property.

                  (4) Lessee agrees that it will not keep or use or offer for
            sale (if sales of goods is a permitted use pursuant to Section 4
            hereof) in or upon the Premises or within the Building, Complex or
            Parcel, any article which may be prohibited by any insurance policy
            in force from time to time covering the Building, Complex or Parcel.
            In the event Lessee's occupancy or conduct of business in or on the
            Premises, Building, Complex or Parcel, whether or not Lessor has


                                       27
<Page>

            consented to the same, results in any increase in premiums for
            insurance carried from time to time by Lessor with respect to the
            Building, Complex or Parcel, Lessee shall pay such increase in
            premiums as Additional Rent within ten (10) days after being billed
            therefor by Lessor. In determining whether increased premiums are a
            result of Lessee's use and occupancy, a schedule issued by the
            organization computing the insurance rate on the Building, Complex
            or Parcel showing the components of such rate shall be conclusive
            evidence of the items and charges making up such rate. Lessee shall
            promptly comply with all reasonable requirements of the insurance
            authority or of any insurer now or hereafter in effect relating to
            the Premises, Building, Complex or Parcel.

                  (5) If any insurance policy carried by either party as
            required by this Section 32 shall be cancelled or cancellation shall
            be threatened or the coverage thereunder reduced or threatened to be
            reduced in any way by reason of the use or occupation of the
            Premises, Building, Complex or Parcel or any part thereof by Lessee
            or any assignee or sublessee of Lessee or anyone permitted by Lessee
            to be upon the Premises, and if Lessee fails to remedy the
            conditions giving rise to said cancellation or threatened
            cancellation or reduction in coverage on or before the earlier of
            (i) forty-eight (48) hours after notice thereof from Lessor, or (ii)
            prior to said cancellation or reduction becoming effective, Lessee
            shall be in default hereunder and Lessor shall have all of the
            remedies available to Lessor pursuant to this Lease.

            B. LESSORS INSURANCE. Lessor covenants and agrees that throughout
the Term it will insure the Building [excluding any property with respect to
which Lessee is obligated to insure pursuant to Subsection 32 (A) (1) (a) above]
against damage by fire and standard extended coverage perils and public
liability insurance in such reasonable amounts with such reasonable deductibles
as required by any-mortgagee or ground lessor, or if none, as would be carried
by a prudent owner of a similar building in the area. In addition, Lessor shall
maintain and keep in force and effect during the Term, rental income insurance
insuring Lessor against abatement or loss of Term Fixed Basic Rent, including
items of Additional Rent, in case of fire or other casualty similarly insured
against, in an amount at least equal to the Term Fixed Basic Rent and Additional
Rent during, at the minimum, one (1) Lease Year hereunder. Lessor may, but shall
not be obligated to, take out and carry any other forms of insurance as it or
the mortgagee or ground lessor (if any) of Lessor may require or reasonably
determine available. A11 insurance carried by Lessor on the Building, Complex or
Parcel shall be included as an Operating Cost pursuant to Subsection 25(A).
Notwithstanding its inclusion as an Operating Cost or any contribution by Lessee
to the cost of insurance premiums by Lessee as provided herein, Lessee
acknowledges that it has no right to receive any proceeds from any such
insurance policies carried by Lessor. Lessee further acknowledges that the
exculpatory provisions of this Lease as set forth in Section 39 and the
provisions of this Section 32 as to Lessee's insurance are designed to insure
adequate coverage as to Lessee's property and business without regard to fault
and avoid Lessor obtaining similar coverage for said loss for its negligence or
that of its agents, servants or employees which could result in additional costs
includable as part of Operating Costs which are payable by Lessee. Lessor will
not carry insurance of any kind on Lessee's furniture or furnishings, or on any
fixtures, equipment, appurtenances or improvements (other than those enumerated
in Exhibit C which belong to Lessor) of Lessee under this Lease and


                                       28
<Page>

Lessor shall not, except as to the aforesaid Exhibit C items owned by Lessor, be
obligated to repair any damage thereto or replace the same.

            C. WAIVER OF SUBROGATION. Any policy or policies of fire, extended
coverage or similar casualty insurance, which either party obtains in connection
with the Premises, Building, Complex or Parcel shall include a clause or
endorsement denying the insurer any rights of subrogation against the other
party (i.e. Lessor or Lessee) for all perils covered by said policy.

Should such waiver not be available, then the policy for which the waiver is not
available must name the other party as an additional named insured affording it
the same coverage as that provided the party obtaining said coverage.

      33. NO OTHER REPRESENTATIONS. No representations or promises shall be
binding on the parties hereto except those representations and promises
contained herein or in some future writing signed by the party making such
representation(s) or promise(s).

      34. QUIET ENJOYMENT. Lessor covenants that if, and so long as, Lessee pays
the Term Fixed Basic Rent and any Additional Rent as herein provided, and
performs the covenants hereof, Lessor and those acting by, through or under
Lessor have done and shall do nothing to affect Lessee's right to peaceably and
quietly have, hold and enjoy the Premises for the Term herein mentioned, subject
to the provisions of this Lease and to any mortgage or deed of trust to which
this Lease shall be subordinate.

      35. INDEMNITY. Lessee shall indemnify and save harmless Lessor and its
agents against and from (a) any and all claims (i) arising from (x) the conduct
or management by Lessee, its subtenants, licensees, its or their employees,
agents, contractors or invitees on the Demised Premises or of any business
therein, or (y) any work or thing whatsoever done, or any condition created
(other than by Lessor or Lessor's agents, servants or contractors for Lessor's
or Lessee's account) in or about the Demised Premises during the Term of this
Lease or during the period of time, if any, prior to the Commencement Date that
Lessee may have been given access to the Demised Premises, or (ii) arising from
any negligent or otherwise wrongful act or omission of Lessee or any of its
subtenants or licensees or its or their employees, agents, contractors or
invitees, and (b) all costs, expenses and liabilities incurred in or in
connection-with each such claim or action or proceeding brought thereon. In case
any action or proceeding be brought against Lessor by reason of any such claim,
Lessee, upon notice from Lessor, shall resist and defend such action or
proceeding. The provisions of this Section 35 shall survive the expiration or
sooner termination of this Lease.

      36. RULES OF CONSTRUCTION/APPLICABLE LAW. Any 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 no implication or inference shall be drawn from the fact that said words
or phrases were so stricken out or


                                       29
<Page>

otherwise eliminated. Each covenant, agreement, obligation or other provision of
this Lease on Lessee's part to be performed, shall be deemed and construed as a
separate and independent covenant of Lessee, 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. This Lease shall
be governed and construed in accordance with the laws of the State of New Jersey
(excluding New Jersey conflict of laws) and by the State courts of New Jersey.
If any of the provisions of this Lease, or the application thereof to any
person or circumstances, shall-to-any extent be invalid or unenforceable, the
remainder of this Lease, or the application of such provision or provisions to
persons or circumstances other than those as to whom or which it is held invalid
or unenforceable, shall not be affected thereby, and every provision of this
Lease shall be valid and enforceable to the fullest extent permitted by law.

      37. APPLICABILITY TO HEIRS AND ASSIGNS. The provisions of this Lease shall
apply to, bind and inure to the benefit of Lessor and Lessee, and their
respective heirs, successors, legal representatives and assigns. It is
understood that the term "Lessor" as used in this Lease means only the owner, a
mortgagee in possession or a term lessee of the Building, so that in the event
of any sale of the Building or of any lease thereof, or if a mortgagee shall
take possession of the Premises, the Lessor named herein shall be and hereby is
entirely freed and relieved of all covenants and obligations of Lessor hereunder
accruing thereafter, and it shall be deemed without further agreement that the
purchaser, the term lessee of the Building, or the mortgagee in possession has
assumed and agreed to carry out any and all covenants and obligations of Lessor
hereunder.

      38. PARKING. Lessor agrees that Lessee, its employees, agents, permitted
subtenants, customers and invitees shall be entitled, in the aggregate, to the
use of those parking spaces as enumerated on the Reference Page, from time to
time, as, when and where available in the parking areas appurtenant to the
Building. Lessor hereby expressly reserves the right, from time to time, to
change the area, level, location and arrangement of the parking areas; to build
multi-story parking facilities; to restrict parking by tenants and to the
occupants of the Building and their employees, agents, permitted subtenants,
customers and invitees; to enforce parking charges (by operation of meters or
otherwise) except that no such parking charge shall be charged Lessee unless the
same is applicable to all Building or Complex tenants with access to the parking
spaces then being charged for; and to close temporarily all or any portion of
the parking areas or other common areas for the purpose of making repairs or
changes thereto and to discourage non-customer parking. If any vehicle of
Lessee, or of any subtenant, licensee, or concessionaire, or of their respective
officers, agents or employees, is parked in any part of the Common Facilities
other than the employee parking area (s) designated therefor by Lessor, Lessee
shall pay to Lessor such reasonable penalty as may be fixed by Lessor from time
to time. All amounts due under the provisions of this Section shall be deemed to
be Additional Rent. Lessee agrees promptly to execute Lessor's standard parking
agreement if, as and when promulgated by Lessor for use in connection with the
Building, provided that Lessee shall have been provided with a copy of such
agreement. Notwithstanding anything contained herein to the contrary, it is
understood and agreed that a gate-controlled area is utilized for covered
parking spaces. The spaces within said covered area shall not be specifically
assigned on an individual basis anal those spaces enumerated on the Reference
Page as being covered shall be undercover but not specifically earmarked for
Lessee, said spaces to be available on a first come first serve


                                       30
<Page>

basis to all those entitled to covered spaces who have been assigned spaces
within said area. The total spaces available within said area shall equal the
total number of people with access to said area. Nothing contained herein shall
be deemed to impose any obligation on Lessor to police the parking area. Lessor
shall enforce the provisions set forth in this Section 38 in a
non-discriminatory manner.

      39. LESSOR'S EXCULPATION. Lessor shall not be liable to Lessee for any
loss suffered by Lessee under any circumstances, including, but not limited to
(i) that arising from the negligence of Lessor, its agents, servants, invitees,
contractors or subcontractors, or from defects, errors or omissions in the
construction or design of the Premises and/or the Building and/or the Complex
and/or the Parcel including the structural and nonstructural portions thereof;
or (ii) for loss of or injury to Lessee or to Lessee's property or that for
which Lessee is legally liable from any cause whatsoever, including but not
limited to theft or burglary; or (iii) for that which results from or is
incidental to the furnishing of or failure to furnish or the interruption in
connection with the furnishing of any service which Lessor is obligated to
furnish pursuant to this Lease; or (iv) for that which results from any
inspection, repair, alteration or addition or the failure thereof undertaken or
failed to be undertaken by Lessor; or (v) for any interruption to Lessee's
business, however occurring. The aforesaid exculpatory Section is to induce the
Lessor, in its judgment, to avoid or minimize covering risks which are better
quantified and covered by Lessee either through insurance (or self-insurance or
combinations thereof if specifically permitted pursuant to this Lease), thereby
permitting potential cost savings in connection with the Operating Costs borne
by Lessee pursuant to Section 25, but is not intended to preclude Lessee from
any cause of action otherwise available to Lessee under this Lease for Lessor's
breach of its obligations under this Lease subject to whatever limitations
otherwise exist under this Lease.

      40. COMMISSION. Lessee and Lessor represent and warrant one to the other
that the Broker, as defined on the Reference Page, is the sole broker with whom
either party has negotiated in bringing about this Lease and Lessee and Lessor
agree to indemnify and hold each other and Lessor's mortgagee(s) harmless from
any and all claims of other brokers and expenses in connection therewith arising
out of or in connection with any conduct inconsistent with the representations
tendered by one to the other herein. In no event shall Lessor's mortgagee(s)
have any obligation to any broker involved in this transaction. In the event
that no broker was involved as aforesaid, then Lessee and Lessor represent and
warrant one to the other that no broker brought about this transaction, and
Lessee and Lessor agree to indemnify and hold each other harmless from any and
all claims of any brokers arising out of or in connection with any conduct
inconsistent with the representations tendered by one to the other herein.

      41. RECORDATION. Lessee shall not record this Lease or a short form
memorandum hereof without the prior written consent of Lessor. If Lessee does
record this Lease or a short form memorandum without the prior written consent
of Lessor, it shall be considered a default under the Lease entitling the Lessor
to terminate the Lessee's occupancy.

      42. NO OPTION. The submission of this Lease Agreement for examination does
not constitute a reservation of, or option for, the Premises, and this Lease
Agreement becomes effective as a Lease Agreement only upon execution and
delivery thereof by Lessor and Lessee.


                                       31
<Page>

      43. DEFINITIONS.

            A. AFFILIATE. Affiliate shall mean any corporation related to Lessee
as a parent, subsidiary or brother-sister corporation so that such corporation
and such party or such corporation and such party and other corporations
constitute a controlled group as determined under Section 1563 of the Internal
Revenue Code of 1986, as amended and as elaborated by the Treasury Regulations
promulgated thereunder or any business entity in which Lessee has more than a
fifty (50%) percent interest.

            B. BUSINESS DAYS AND BUILDING HOURS. As used in this Lease, the
"Business Days" and the "Building Hours" shall be Monday through Friday, 8:00
a.m. to 6:00 p.m., and on Saturdays from 8:00 a.m. to 1:00 p.m., excluding those
Federal and/or State holidays observed by the employees of Lessor, except that
Common Facilities lighting in the Building, the Complex and Parcel shall be
maintained for such additional hours as, in Lessor's sole judgment, is necessary
or desirable to insure proper operation of the Building, the Complex and Parcel.

            C. COMMON FACILITIES. Common Facilities shall include, by way of
example and not by way of limitation, the parking areas; ingress and egress
areas to the Complex; lobby; elevator(s); public hallways; public lavatories;
all other general Building or Complex facilities that service all Building
tenants; air conditioning rooms; fan rooms; janitors' closets; electrical
closets; telephone closets; elevator shafts and machine rooms; flues; stacks;
pipe shafts and vertical ducts with their enclosing walls. Lessee's use of those
Common Facilities not open to all tenants is subject to Lessor's consent which
may be denied for any reason. Lessor may at any time close temporarily any of
the Common Facilities to make repairs or changes therein or to effect
construction, repairs or changes within the Building, Complex or Parcel, or to
discourage non-tenant parking or to prevent the dedication of the same, and may
do such other acts in and to any of the Common Facilities as in its judgment may
be desirable to improve the convenience thereof but shall always in connection
therewith endeavor to minimize any inconvenience to Lessee.

            D. FORCE MAJEURE. Force Majeure shall mean and include those
situations beyond either party's control, including by way of example and not by
way of limitation, acts of God; accidents; repairs; strikes; shortages of labor,
supplies or materials; inclement weather; or, where applicable, the passage of
time while waiting for an adjustment of insurance proceeds. Any time limits
required to be met by either party hereunder, whether specifically made subject
to Force Majeure or not, except those related to the payment of Term Fixed Basic
Rent or Additional Rent and except as to the time periods set forth in Section
27, shall, unless specifically stated to the contrary elsewhere in this Lease,
be automatically extended by the number of days by which any performance called
for is delayed due to Force Majeure.

            E. LESSEE'S PERCENTAGE. The parties agree that Lessee's Percentage,
as defined on the Reference Page, reflects and will be continually adjusted to
reflect the sum arrived at by dividing the gross square feet of the area rented
to Lessee (including an allocable share of all Common Facilities) as set forth
in Section 1 [the numerator], plus any additional gross square footage leased
from time to time pursuant to this Lease, by the total number of gross square
feet of the Complex (or additional buildings that may be constructed within the
Parcel), [the denominator], measured outside wall to outside wall less five (5%)
percent vacancy allowance of


                                       32
<Page>

the Complex. Lessor shall have the right to make changes or revisions in the
Common Facilities of the Building or Complex so as to provide additional leasing
area. Lessor shall also have the right to construct additional buildings in the
Parcel for such purposes as Lessor may deem appropriate and subdivide the lands
for that purpose if necessary, and upon so doing, the Parcel shall become the
subdivided lot on which the Building in which the Demised Premises is located.
If any service provided for in Subsection 25 (A) or any utility provided for in
Subsection 25(B) is separately billed or separately metered within the Building
or within the Complex, then the square footage so billed or metered shall be
deemed vacant and if applicable subject to the Occupancy Adjustment set forth in
Subsection 25 (H). Lessee understands that as a result of changes in the layout
of the Common Facilities from time to time occurring due to, by way of example
and not by way of limitation, the rearrangement of corridors, the aggregate of
all tenant Building proportionate shares or complex proportionate shares may be
equal to, less than or greater than one hundred (100%) percent.

      44. LEASE COMMENCEMENT. Notwithstanding anything contained herein to the
contrary, if Lessor, for any reason whatsoever, including Lessor's negligence,
cannot deliver possession of the Premises as provided for in Subsection 29 (A)
to Lessee at the commencement of the agreed Term as set forth in Section 2, this
Lease shall not be void or voidable, nor shall Lessor be liable to Lessee for
any loss or damage resulting therefrom, but in that event, the Lease Term shall
be for the full Term as specified above to commence from and after the date
Lessor shall have delivered possession of the Premises to Lessee or from the
date Lessor would have delivered possession of the Premises to Lessee but for
Lessee's failure to timely supply to Lessor such drawings and/or information
required by Exhibit C or for any other reason attributable to Lessee (herein the
"Commencement Date") and to terminate midnight of the Expiration Date, and if
requested by Lessor, Lessor and Lessee shall, by a writing signed by the
parties, ratify and confirm said commencement and termination dates. Nothing
contained herein shall be deemed to modify the commencement of the Lease Term as
set forth in Section 2 and Lessee's obligations hereunder if Lessor is unable to
deliver the Demised Premises on the Commencement Date by reason of Lessee's
failure to comply with the requirements of Subsection 29(B).

      45. NOTICES. Any notice by either party to the other shall be in writing
and shall be deemed to have been duly given only if (a) delivered personally or
(b) sent by registered mail or certified mail in a postpaid envelope or by
regulated carrier service with return receipt or (c) sent by nationally
recognized overnight courier service such as Federal Express, addressed if to
Lessee, at 401 Hackensack Avenue, Fifth Floor, Hackensack, New Jersey 07601,
Attention: Arnold Lippa; with copy to Friedman Siegelbaum LLP, 7 Becker Farm
Road, Roseland, New Jersey 07068-1757, Attention: Joseph Siegelbaum, Esq.; if to

Lessee or Lessor, respectively, may designate in writing. Notice shall be deemed
to have been duly given upon its receipt or rejection as evidenced by a bill of
lading or return receipt or upon delivery if personally served.

      46. ACCORD AND SATISFACTION. No payment by Lessee or receipt by Lessor of
a lesser amount than the Monthly Fixed Basic Rent and Additional Rent payable
hereunder shall be deemed to be other than a payment on account of the earliest
stipulated Monthly Fixed


                                       33
<Page>

Basic Rent and Additional Rent, nor shall any endorsement or statement on any
check or any letter accompanying any check or payment for Fixed Basic Rent or
Additional Rent be deemed an accord and satisfaction, and Lessor may accept such
check or payment without prejudice to Lessor's right to recover the balance of
such Fixed Basic Rent and Additional Rent or pursue any other remedy provided
herein or by law.

      47. EFFECT OF WAIVERS. No failure by Lessor to insist upon the strict
performance of any covenant, agreement, term or condition of this Lease, or to
exercise any right or remedy consequent upon a breach thereof, and no acceptance
of full or partial monthly Fixed Basic Rent or Additional Rent during the
continuance of any such breach, shall constitute a waiver of any such breach or
of such covenant, agreement, term or condition. No consent or waiver, express or
implied, by Lessor to or of any breach of any covenant, condition or duty of
Lessee shall be construed as a consent or waiver to or of any other breach of
the same or any other covenant, condition or duty, unless in writing signed by
Lessor.

      48. LESSOR'S RESERVED RIGHT. Lessor and Lessee acknowledge that the
Premises are in a Building and Complex which are not open to the general public.
Access to the Building or Complex is restricted to Lessor, Lessee, their agents,
employees and contractors and to their invited visitors. In the event of a labor
dispute including a strike, picketing, informational or associational activities
directed at Lessee or any other tenant, Lessor reserves the right unilaterally
to alter Lessee's ingress and egress to the Building or Complex or make any
other change in operating conditions to restrict pedestrian, vehicular or
delivery ingress and egress to a particular location.

      49. FEES AND EXPENSES. The parties agree that either party who brings an
action to enforce any obligation of the other party under this Lease shall, if
successful, be entitled to recover from said unsuccessful party all reasonable
attorneys' fees and other reasonable expenses incurred in enforcing said
obligation against the unsuccessful party, this to survive the expiration or
sooner termination of this Lease.

      50. CORPORATE AUTHORITY. If Lessee is a corporation, Lessee represents and
warrants that this Lease and the undersigned's execution of this Lease has been
duly authorized and approved by the corporation's Board of Directors. The
undersigned officers and representatives of the corporation executing this Lease
on behalf of the corporation represent and warrant that they are officers of the
corporation with authority to execute this Lease on behalf of the corporation,
and within fifteen (15) days of execution hereof, Lessee will provide Lessor
with a corporate resolution confirming the aforesaid.

      51. NUMBER AND GENDER. The terms "Lessor" and "Lessee" or any pronoun used
in place thereof shall indicate and include Landlord and Tenant, the masculine
or feminine, the singular or plural number, individuals, firms or corporations,
and their and each of their respective successors, executors, administrators and
permitted assigns, according to the context hereof. In any case, where this
Lease is signed by more than one person, the obligations hereunder shall be
joint and several.

      52. LESSEE RESTRICTION. Lessee acknowledges that it has been advised by
Lessor that Lessor shall be precluded from permitting leases in the Building or
Complex to any


                                       34
<Page>

cafeteria/restaurant operation including take-out service, coffee wagon service,
delivery service and/or catering service, and Lessee agrees that Lessor's
refusal to consent to any sublease or assignment proposed by Lessee to any of
the aforesaid entities shall not be considered unreasonable.

      53. GOVERNMENT REQUIREMENTS. In the event of the imposition of Federal,
State, or local governmental control, rules, regulations, or restrictions on the
use or consumption of energy or other utilities or with respect to any other
aspect of this Lease during the Term, both Lessor and Lessee shall be bound
thereby. In the event of a difference in interpretation of any governmental
control, rule, regulation or restriction between Lessor and Lessee, the
interpretation of Lessor shall prevail, and Lessor shall have the right to
enforce compliance, including the right of entry into the Premises to effect
compliance.

      54. YEAR 2000 COMPLIANCE. The Lessor and Lessee acknowledge the existence
of what is commonly referred to as the Year 2000 problem. Lessor shall endeavor
to ensure that all Computer Controlled Facility Components are Year 2000
Compliant by, among other things, seeking written confirmation from the
component and/or systems manufacturer and taking such other measures to prevent
and/or mitigate any Year 2000 problems, all as part of the Operating Costs for
the Building, Complex and Parcel and chargeable as such as Additional Rent as
provided for in this Lease.

            A. Computer Controlled Facility Components refers to software driven
      technology and embedded microchip technology. This includes, but is not
      limited to, programmable thermostats, HVAC controllers, elevator
      controllers, utility monitoring and control systems, fire detection and
      suppression systems, alarms, security systems and any other Building
      control systems utilizing microcomputer, minicomputer, or programmable
      logic controllers.

            B. Year 2000 Compliant means Computer Controlled Facility Components
      that accurately process date/time data (including, but not limited to,
      calculating, comparing and sequencing) from, into, and between the
      twentieth and twenty-first centuries and the years 1999 and 2000 and leap
      year calculations.

            C. Lessee acknowledges that Lessor relies upon the manufacturer of
      said Computer Controlled Facility Components and/or systems to ensure that
      they are Year 2000 Compliant and that Lessor cannot and does not warrant
      or represent that said components and/or systems will in fact be Year 2000
      Compliant. Lessee hereby waives any claim against Lessor, to include but
      not be limited to, any business interruption claim, property damage claim
      or constructive eviction claim resulting from any failure of said Computer
      Controlled Facility Components and/or systems to be Year 2000 Compliant.

      55. LIMITATION OF LESSOR'S LIABILITY. Notwithstanding anything to the
contrary provided in this Lease, it is specifically understood and agreed, such
agreement being a primary consideration for the execution of this Lease by
Lessor, that there shall be absolutely no personal liability on the part of
Lessor, its constituent members (to include but not be limited to officers,
directors, partners and trustees), their respective successors, assigns or any
mortgagee in


                                       35
<Page>

possession (for the purposes of this Section, collectively referred to as
"Lessor"), with respect to any of the terms, covenants and conditions of this
Lease, and that Lessee shall look solely to the equity of Lessor in the Building
for the satisfaction of each and every remedy of Lessee in the event of any
breach by Lessor of any of the terms, covenants and conditions of this Lease to
be performed by Lessor, such exculpation of liability to be absolute and without
any exceptions whatsoever. A deficit capital account of any portion in Lessor
shall not be deemed an asset or property of Lessor. The foregoing limitation of
liability shall be noted in any judgment secured against Lessor and in the
judgment index.

      IN WITNESS WHEREOF, the parties hereto have hereunto set their hands and
seals the day and year first above written.

                              RULES AND REGULATIONS

      1. No sign, placard, picture, advertisement, name or notice shall be
installed or displayed on any part of the outside or inside of the Building if
visible from a public area without prior written consent of the Lessor. Lessee
shall be permitted an exterior sign at a location to be agreed to by Lessor.
Lessee shall pay all costs of installation, maintenance, and operation of said
sign. Lessor shall have the right to remove, at Lessee's expense and without
notice, any sign installed or displayed in violation of this rule. All approved
signs or lettering in public corridors shall be inscribed or affixed at the
expense of Lessee by a person or vendor chosen by Lessor and in conformance with
the Building standard signage program. In addition, Lessor reserves the right to
change from time to time the format of the signs or lettering and to require
previously approved signs or lettering to be appropriately altered. Lessor
agrees to install, at Lessee's sole cost and expense, Building standard signage

      THIS SUBORDINATION, ATTORNMENT AND NON-DISTURBANCE AGREEMENT ("this
Agreement") is made this _______ day of ________________, 1999, by and among
UNITED STATES FIDELITY AND GUARANTY CO., having an address c/o Criimi Mae

Pennsylvania 19102 (the "Landlord"); and DOV PHARMACEUTICALS INC., a New Jersey
corporation, with offices at 401 Hackensack Avenue, Fifth Floor, Hackensack, New
Jersey 07601 (the "Tenant").

                                    RECITALS

      A. The Landlord and the Tenant have entered into a lease (hereinafter
referred to as the "Lease") dated __________________, 1999, by which the
Landlord has leased to the Tenant certain premises (the "Leased Premises")
located on a portion of that land, situate and lying in Hackensack, New Jersey,
which is described in EXHIBIT A attached hereto and made a part hereof (the
"Property").

      B. The Lender is the holder of a Mortgage and Security Agreement and
Assignment of Leases and Rents (the "Indenture") dated February 20, 1997
recorded among the Land Records of Bergen County, New Jersey from the Landlord
to the Lender, securing a loan made by the Lender to the Landlord, covering the
property (including the Leased Premises).

      C. The Tenant has agreed that the Lease shall be and is subject and
subordinate to the lien of the Indenture, and that so long as the Tenant is not
in default under the Lease the Tenant is assured that the Lease and the Tenant's
rights thereunder will not be terminated by any foreclosure proceeding brought
under the provisions of the Indenture.

      NOW, THEREFORE, FOR AND IN CONSIDERATION of the mutual entry into this
Agreement by the parties hereto, and for other good and valuable consideration,
the receipt and adequacy of which are hereby acknowledged by each party hereto,
and anything contained in the provisions of the Lease to the contrary
notwithstanding, the parties hereto hereby agree as follows:

      Section 1. Subordination. The Lease is and shall be subject and
subordinate to the lien, operation and effect of the Indenture and all renewals,
modifications, consolidations, replacements, increases and extensions thereof.

      Section 2. Effect of Foreclosure.

      2.1. Foreclosure under Indenture. If any foreclosure proceeding is brought
under the provisions of the Indenture,
<Page>

      2.1.1. (a) such proceeding shall not operate to terminate the Lease or the
Tenant's rights thereunder (except that such proceeding shall operate to
terminate any option to purchase, right of first refusal or other right to
purchase any or all of the Leased Premises held by the Tenant under the
provisions of the Lease), and (b) the Lender, for itself and its heirs, personal
representatives, successors and assigns shall not terminate the Lease or the
Tenant's rights thereunder, or disturb the Tenant in its possession of the
Leased Premises, provided that the Tenant is not then in default under the Lease
beyond applicable periods of notice and grace and continues to pay the rent and
otherwise to perform its obligations hereunder and under the provisions of the
Lease; but

      2.1.2. neither the Lender nor any purchaser at such foreclosure shall be:

      (a) liable for any breach, act or omission of the Landlord or any other
person under the Lease,

      (b) subject to any offset or defense which the Tenant may have against the
Landlord or any other person under the Lease, bound by any payment of rent made
by the Tenant to the Landlord or any other person for a period beyond the month
during which such foreclosure proceeding is ratified,

      (d) bound by any amendment or modification of the Lease made without the
Lender's express, written consent thereto,

      (e) bound by any notice given by the Tenant to the Landlord pursuant to
the provisions of the Lease or otherwise, unless and until a copy of it is given
to the Lender at the address stated above, or

      (f) liable for any security deposit or other payment made under the Lease,
unless both (i) the Landlord has actually delivered it in cash to the Lender or
such purchaser, as the case may be, and (ii) it has been specifically
identified, and accepted by the Lender or such purchaser, as the case may be, as
such and for such purpose.

      2.1.3. In such event, the Lender shall sell the Leased Premises subject to
the operation and effect of the Lease.

      2.2. Foreclosure under Other Instruments or Liens.

      2.2.1. The Tenant shall not subordinate the Lease or any of the Tenant's
right, title and interest in and to the Leased Premises thereunder to the lien
of any mortgage, deed of trust, other security agreement or other instrument
other than the Indenture.

      2.2.2. If any foreclosure proceeding is brought by any person under any
instrument or lien (other than that of the Indenture) against the Landlord's
estate in the Leased Premises (whether or not (a) the Lender has consented to
such instrument or lien, or (b) this Lease is subordinate thereto), the Tenant
shall promptly attorn to the purchaser in such foreclosure proceeding, upon all
of the terms, covenants and conditions of the Lease, provided that such
purchaser agrees with the Tenant in writing to recognize the Tenant's rights
under the Lease for the original term and the term of any renewal thereof
permitted the Tenant by the provisions of


                                       2
<Page>

the Lease, so long as the Tenant continues to pay the rent and otherwise to
perform its obligations hereunder and under the provisions of the Lease.

      2.3. Attornment to Persons Owning or Controlling Leased Premises. The
Tenant shall:

      2.3.1. attorn to (a) the Lender whenever the Lender is in possession of
the Leased Premises; (b) any receiver appointed by or for the Lender in any
action to take possession of the Leased Premises; and (c) any party hereafter
acquiring title to the Leased Premises while the Lease remains in effect, and

      2.3.2. execute and deliver to the Lender, promptly on its receipt of a
written request therefor from the Lender, an appropriate agreement of attornment
thereunder confirming that the Tenant is and then remains bound under all of the
terms, covenants and conditions of the Lease.

      Section 3. Election by Lender. If the Lender, pursuant to the provisions
of the Assignment of Leases and Rents dated February 20, 1997, from the Landlord
to the Lender, and covering the Property, elects to require the Tenant to pay to
the Lender the rent and other charges payable by the Tenant under the provisions
of the Lease, then (unless and until the Lender cancels such election by written
notice to the Tenant),

      3.1. the Tenant shall be bound to the Lender and shall attorn to the
Lender as its landlord and Landlord shall release Tenant from any rental
payments made directly to Lender, and

      3.2. the Lender shall accept such attornment, upon the terms set forth in
the provisions of paragraphs 2.1.1 and 2.1.2, and provided that the conditions
precedent set forth therein are satisfied at the time of such election.

      Section 4. Landlord's Defaults.

      4.1. Notices to Landlord. Anything contained in the provisions of the
Lease to the contrary notwithstanding, the Tenant shall provide to the Lender a
copy of each notice which the Tenant may from time to time serve upon the
Landlord pursuant to the provisions of the Lease or otherwise in connection
therewith, and no such notice given to the Landlord shall be effective unless
such copy is provided to the Lender.

      4.2. Opportunity to Cure. Before the Lease is terminated or any of the
Landlord's rights thereunder or in connection therewith are forfeited or
adversely affected because of any default by the Landlord thereunder, the Tenant
shall give express, written notice of such default to the Lender. The Lender,
following such notice, shall have the right, but not the obligation, to cure any
such default within (a) fifteen (15) days if such default may be cured upon the
payment of money, or (b) thirty (30) days for any other default, unless the cure
requires the Lender to obtain possession of the Leased Premises. If Lender's
cure of the default requires the Lender to obtain possession of the Leased
Premises, the thirty (30) day period shall not commence until Lender acquires
possession of the Leased Premises, so long as the Lender proceeds promptly to
acquire possession of the Leased Premises with due diligence, by foreclosure or
otherwise. All payments so made, and all things so done and performed, by the
Lender shall be as effective to


                                       3
<Page>

prevent the Landlord's rights from being forfeited or adversely affected because
of such default as if it had been done and performed by the Landlord.

      Section 5. [Intentionally Deleted].

      Section 6. Acknowledgment of Assignment of Lease. The Tenant hereby
acknowledges that the Lease has been or will be assigned by the Landlord to the
Lender by an assignment of leases and rents, and agrees that from and after the
date hereof, unless the Lender has first consented thereto. expressly and in
writing, the Tenant will (a) pay no rent under the Lease more than thirty (30)
days before its due date, (b), except as may be expressly permitted by the
provisions of the Lease, pay such rent when due, without any deduction, set-off
or counterclaim whatsoever, and (c) not surrender its leasehold estate.

upon its execution and delivery by each party hereto.

                            FIRST AMENDMENT TO LEASE

      AGREEMENT made as of July 31, 2000 ("this Agreement") by and between
STELLAR CONTINENTAL LLC, a Delaware limited liability company with an office at
156 William Street, New York, New York 10038 ("Lessor"), and DOV PHARMACEUTICALS
INC., 433 Hackensack Avenue, Hackensack, New Jersey 07601 ("Lessee").

                                   WITNESSETH:

      WHEREAS, Lessor's predecessor-in-interest and Lessee entered into a lease
dated May 24, 1999 (the "Lease") respecting approximately 4,922 gross rentable
square feet on the lobby level (the "Premises") of the building known as 433
Hackensack Avenue, Hackensack, New Jersey (the "Building"), as the Premises are
more particularly delineated on Schedule A annexed to and a part of the Lease;
and

      WHEREAS, the Building is part of an office complex consisting of 401, 407,
411 and 433 Hackensack Avenue, Hackensack, New Jersey, which complex is known as
Continental Plaza (the "Complex"); and

      WHEREAS, Lessee wishes to lease and hire from Lessor, additional space
consisting of approximately 2,263 gross rentable square feet on the lobby level
of the Building (the "First Additional Premises'); and

      WHEREAS, Lessee has advised Lessor that Lessee may require in the future
additional space at the Complex of not less than 8,000 rentable square feet (the
"Second Additional Premises').

      NOW, THEREFORE, in consideration of the sum of Ten ($10.00) Dollars and
other good and valuable consideration exchanged by Lessor and Lessee, the
receipt and sufficiency of which hereby expressly are acknowledged; it is
AGREED:

      1. For the purposes of this Agreement, capitalized terms used herein and
not otherwise defined herein shall have the respective meanings ascribed to them
in the Lease.

      2. Lessor and Lessee hereby confirm that the current Expiration Date of
the Lease is June 25, 2004.

      3. (a) Lessor hereby leases to Lessee, and Lessee hereby hires from
Lessor, the First Additional Premises (as shown on Exhibit A annexed hereto and
made a part hereof) for the period commencing September 1, 2000 and expiring on
the Expiration Date (the "First Additional Premises Term").

            (b) Lessor, at Lessor's sole cost and expense and using contractors
of Lessor's choosing, shall perform the work to prepare the First Additional
Premises for Lessee's occupancy shown on Exhibit B hereto ("Landlord's Work") on
or prior to September 1, 2000. If the work has not been substantially completed
(other than punchlist items), through no fault of

<Page>

Lessee, on or before such date, the commencement of the First Additional
Premises Term nonetheless shall commence but Lessee shall have no responsibility
for rent and additional rent for the First Additional Premises until the earlier
of: (i) substantial completion of Landlord's Work and (ii) Lessee taking
possession of the First Additional Premises.

      4. During the First Additional Premises Term, with respect to the First
Additional Premises only, the Annual Fixed Basic Rent shall be $75,810.50
(inclusive of $1.50 per gross rentable square foot per annum constituting the
Electric Rent Inclusion Factor for the First Additional Premises), and the
Monthly Fixed Basic Rent shall be $6,317.54.

      5. With respect to the First Additional Premises, only: (a) Lessee's
Percentage shall be 0.39%; (b) on the Reference Page at subsections (2)(A), (B)
and (C), "Calendar Year 1999" shall be deleted and replaced with "Calendar Year
2000"; (c) Landlord's Work shall be completed by September 1, 2000 and consist
of repainting and recarpeting the First Additional Premises at Building standard
at Landlord's sole cost and expense not in excess of $13,800 in total; (d)
Lessee shall be entitled to nine (9) non-reserved parking spaces of which six
(6) shall be in the covered garage; and (e) Lessee shall be given rights
respecting directory listings, keys and signage in proportion to the increase in
gross rentable square footage by reason of Lessee leasing the First Additional
Premises.

      6. Except as provided in this Agreement, the letting of the First
Additional Premises shall be upon all of the terms and conditions of the Lease.

      7. (a) Not earlier than the 21-month anniversary nor later than the
22-month anniversary of the date of this Agreement, time being of the essence,
Lessee may notify Lessor in writing ("Lessee's Expansion Notice") whether Lessee
wishes to lease the Second Additional Premises. Silence shall be deemed waiver
by Lessee of the right, but not a default under the Lease. Unless Lessee shall
have timely sent Lessee's Expansion Notice, such right of Lessee (and obligation
of Lessor) automatically shall cease and expire. If there shall occur and be
continuing any uncured Event of Default under the Lease at any time from and
after Lessee's Expansion Notice, Lessee shall be conclusively deemed to have
withdrawn Lessee's Expansion Notice, ab initio, and to have waived any further
right to subsequently send Lessee's Expansion Notice.

            (b) Promptly after receipt of Lessee's Expansion Notice, Lessor
shall send to Lessee a list of then available space at the Complex comprising a
minimum of 8,000 contiguous gross rentable square feet along with the rent,
additional rent and other material terms and conditions applicable to such space
or, if no such space exists, a statement to that effect ("Lessor's Offer
Notice"). Promptly after receipt of Lessor's Offer Notice, Lessor and Lessee
shall commence good faith negotiations to formalize a mutually acceptable lease
for the Second Additional Premises if such space and the terms of the proposed
letting are acceptable to Lessee.

            (c) Upon entering into the lease for the Second Additional Premises,
the Term and all other provisions of the Lease (except those specific to the
Second Additional Premises) of the Lease automatically shall be deemed to have
been extended to and including June 25, 2009; however, Lessee shall have the
option, upon taking possession of the Second Additional Premises and making
payment of the first installment of Monthly Fixed Basic Rent therefore, of

<Page>

terminating the Lease only with respect to the First Additional Premises, such
right to be exercised, if at all, not later than five (5) business days of the
payment of such first installment of Monthly Fixed Basic Rent for the Second
Additional Premises, time being of the essence.

            (d) In determining whether negotiations for the Second Additional
Premises are being conducted in good faith, there shall be taken into account
the size and location of the space, the attractiveness of the space, the amount
of Landlord's Work to be done, the credit worthiness of Lessee at the time and
whether Lessee has fully and timely paid and performed its obligations under the
Lease (as amended to the date of the negotiations).

            (e) Lessor shall have no liability to Lessee if at the time of
Lessee's Expansion Notice there is no space at the Complex suitable for the
Second Additional Premises (i.e., there is no vacant unit of at least 8,000
contiguous gross rentable square feet at the Complex). Until such time as
Lessor's Offer Notice identifies vacant space at the Complex suitable for the
Second Additional Premises, Lessee's Expansion Notice shall remain open for
response by Lessor. In no event shall any vacant space be unsuitable because of
any reason other than gross rentable square footage including, without
limitation, rent and other material provisions.

      8. Lessee represents and warrants to Lessor that Cushman & Wakefield of
New Jersey, Inc. ("Broker") is the sole broker with whom Lessee has dealt in
bringing about this Agreement. Lessee and Lessor each agrees to hold the other
harmless and indemnify and defend the other from and against any and all loss,
cost, liability, damage and expense arising out of the inaccuracy of the
representation contained in the preceding sentence. Lessor shall pay Broker any
fees or commissions due Broker as a result of this Agreement pursuant to the
terms of a separate agreement with Broker.

      9. Lessee and Lessor each represents, warrants and covenants that the
other is not in default under any of its obligations under the Lease and that,
to the best of its knowledge, the other is not in default of its obligations
under the Lease, and no event has occurred nor do any circumstances exist which,
with lapse of time or notice or both, would constitute a default by Lessor or
Lessee under the Lease as modified by this Agreement.

      10. Except as modified by this Agreement, the Lease and all of the
covenants, agreements, terms, provisions and conditions thereof shall remain in
full force and effect and are hereby ratified and affirmed. The covenants,
agreements, terms, provisions and conditions contained in this Agreement shall
bind the parties hereto and their respective successor and assigns and shall
inure to the benefit of the parties hereto and their respective permitted
successors and assigns. In the event of any conflict between the provisions of
this Agreement and the Lease, the provisions contained in this Agreement shall
prevail and be paramount. From and after the date hereof, "Demised Premises" and
"Premises" also shall include the First Additional Premises.

      11. The submission of this Agreement for examination does not constitute a
reservation of, or option for, the First Additional Premises or the Second
Additional Premises, and this Agreement becomes binding and effective only upon
execution and delivery thereof by Lessor and Lessee.

<Page>

      IN WITNESS WHEREOF, Lessor and Lessee have entered into this Agreement as
of the day and year first written above, and acknowledge one to the other that
they possess the requisite authority to enter into this transaction and to sign
this Agreement.
