                                LEASE AGREEMENT
                                ---------------

        This lease entered into on the 29th day of March, 1994, by and between
BF REALTY INVESTORS ROCHESTER II LIMITED PARTNERSHIP, an Ohio limited
partnership with an office at 1241 Dublin Road, Columbus, Ohio 43215,
hereinafter called "Landlord," and WORLD OF SCIENCE, INC., a New York
corporation with an office at 900 Jefferson Road, Building 4, Rochester, New
York 14625, hereinafter called "Tenant."

        Upon the terms and subject to the conditions hereinafter set forth, 
Landlord leases to Tenant, and Tenant leases from Landlord, the property 
hereafter described.

(S)1.  THE LEASED PREMISES. The property hereby leased to Tenant, upon and
       ------------------- 
subject to the terms, covenants, conditions and provisions hereof, is commonly
known as 275 Commerce Drive, Rochester, New York and being more particularly
described in Schedule A attached hereto and made a part hereof, together with
all improvements now or hereafter located thereon (the "leased premises").

        The lease is subject to applicable zoning and building ordinances and 
regulations, conditions, restrictions, rights-of-way, and easements of record 
and the condition and state of repair of the leased premises.

(S)2.  TERM. The term of this lease shall be a period of sixteen (16) months, 
       ----
commencing on the 1st day of April, 1994, and ending on the 31st day of July, 
1995. Notwithstanding the commencement date set forth in the immediately 
preceding sentence, Landlord shall make the leased premises available to Tenant 
after the date hereof and prior to such commencement date for the purposes of 
remodeling, decorating, furnishing and equipping the leased premises. The use of
the leased premises prior to the commencement date for such work shall not
create a landlord-tenant relationship between the parties, nor constitute
occupancy of the lease premises for the commencement of base rent, but the
provisions of (S)(S)6, 8, 10, 11, 12, 16 and 37 of this lease shall apply.

(S)3.  RENT. Tenant does hereby agree to pay as base rent for the Premises the
       ---- 
sum of One Hundred Fifty Thousand Dollars ($150,000.00) payable in advance in
monthly installments of Ten Thousand Dollars ($10,000.00) on the first day of
each and every month during the term of this lease without demand, deduction or
set-off; provided, however, that the

 
obligation to pay base rent shall commence on May 1, 1994. Rent checks shall be 
made payable to Landlord and shall be mailed to 1241 Dublin Road, Columbus, Ohio
43215. 

(S)4.  ADDITIONAL RENT. In addition to the base rent, Tenant shall pay as
       --------------- 
additional rent during the term of this lease: all taxes, assessments and other
governmental charges (including taxes, assessments and other governmental
charges paid prior to the commencement date of the term of this lease to the
extent they relate to any period of time after such commencement date), all
public and private utility charges, all premiums on insurance policies required
by the terms hereof and except as otherwise set forth in this lease, all other
expenses and charges, which during the continuance of this lease, shall arise,
be levied, assessed, charged or imposed upon or with respect to, or be incurred
in connection with, the ownership, possession, rent, use, occupation, operation,
maintenance, repair and alteration of the leased premises; provided, however,
that nothing herein shall be construed to require Tenant to pay any income or
franchise taxes imposed on Landlord. If permitted by the applicable governmental
authority, Tenant may pay assessments in installments in which event Tenant
shall only be liable for installments due and payable during the term of this
lease. All taxes, assessments, and governmental charges shall be pro-rated so
that tenant shall pay only those costs which are attributable to its period of
occupancy.

(S)5.  OPTION TO RENEW. If, and only if, Tenant shall have fully done, performed
       ---------------
and observed all of the terms, covenants and conditions required hereunder to be
done, performed or observed by it, then Tenant shall have the right to renew
this lease for a renewal term of one (1) year.

        If, after having renewed the lease for the first renewal term Tenant has
continued to observe and perform all of its obligations under this lease, Tenant
shall have the right to renew this lease for a second renewal term of one (1) 
year. If, after having renewed the lease for the second renewal term Tenant has 
continued to observe and perform all of its obligations under this lease, Tenant
shall have the right to renew this lease for a third renewal term of one (1) 
year.

        All renewal terms shall be upon all of the same terms, covenants and 
conditions as the initial term of this lease, except that the rent shall be as 
hereinafter provided. Such options to renew shall be exercised by notice in 
writing to Landlord on or before one hundred five (105) days prior to the 
expiration of the original or then renewal term, as the case may be.

                                      -2-

 
        The base rent for the first renewal term shall be One Hundred Seventy 
Thousand Dollars ($170,000) payable in advance in monthly installments of 
Fourteen Thousand One Hundred Sixty-Six and 67/100 Dollars ($14,166.67) on the 
first day of each and every month during the first renewal term without demand, 
deduction or setoff. The base rent for the second renewal term shall be One 
Hundred Eighty Thousand Dollars ($180,000) payable in advance in monthly 
installments of Fifteen Thousand Dollars ($15,000) on the first day of each and 
every month during the second renewal term without demand, deduction or setoff. 
The base rent for the third renewal term shall be One Hundred Ninety Thousand 
Dollars ($190,000) payable in advance in monthly installments of Fifteen 
Thousand Eight Hundred Thirty-Three and 33/100 Dollars ($15,833.33) on the first
day of each and every month during the third renewal term without demand, 
deduction or setoff.

        Except where the context otherwise requires or otherwise is indicated, 
the phrase "the term of this lease" whenever used in this lease shall be 
construed to include any renewal terms for which Tenant has exercised its option
or options set forth in this section.

(S)6.  USE OF PREMISES AND SIGNS. A. Tenant shall be permitted to use the leased
       -------------------------
premises for a warehouse, distribution center and offices and for no other
purposes, without the prior written consent of Landlord, which consent shall not
be unreasonably withheld.

        B. The use by Tenant of the leased premises shall be in a careful, safe,
legal, and proper manner, and Tenant shall not permit the leased premises to be 
used for any unlawful purposes, nor commit or suffer any waste.

        C. Tenant shall not place any sign on the exterior of the building 
comprising part of the leased premises without first obtaining the approval of 
the Landlord. Approval by Landlord for any sign shall not be unreasonably
withheld and each sign must comply with all applicable governmental laws,
ordinances and regulations. During the term of this Lease, Tenant shall maintain
said signs in a good state of repair and shall save Landlord harmless from any
loss, cost or damage that may occur as a result of the maintenance of said signs
or the lack thereof. At the end of the term, Tenant shall remove said signs at
its sole cost and expense, and shall repair any material damage resulting from
such removal.

(S)7.  COMPLIANCE WITH LAWS. A. Except as stated herein, Tenant shall,
       --------------------
throughout the term of this lease at no cost or expense whatsoever to Landlord,
promptly comply, or

                                      -3-

 
cause compliance, with all laws, ordinances, orders, rules, regulations and 
requirements of all federal (including the Americans with Disabilities Act), 
state, county and municipal governments and all departments, commissions, boards
and officers thereof, whether present or future, foreseen or unforeseen, 
ordinary or extraordinary, and whether or not the same shall be presently within
the contemplation of Landlord and Tenant which may be applicable to Tenant's use
of the leased premises.

        B. Except as expressly provided in this lease, no abatement, diminution
or reduction in rent, or any other charges required to be paid by Tenant
pursuant hereto, shall be claimed by or allowed to Tenant for an inconvenience
or interruption, cessation, or loss of business caused, directly or indirectly
by any present or future laws, ordinances, rules, regulations, requirements or
orders to the federal, state, county, township or municipal governments or any
other lawful authority whatsoever, or by priorities, rationing or curtailment of
labor or materials, or by war, civil commotion, strikes, or riots, or any matter
or thing resulting therefrom, or by any other cause or causes beyond the control
of Landlord, nor shall this lease be affected by any such causes.

(S)8.  ALTERATIONS, MAINTENANCE AND REPAIRS. Tenant takes the leased premises
       ------------------------------------
in an "as is" condition. Tenant will comply with all building code requirements 
and government regulations, including the Americans with Disabilities Act, in 
the performance of any alterations. Tenant may, at its own cost and expense, 
make all alterations, improvements and installations in or to the leased 
premises as it may require in connection with its use and occupancy thereof; 
provided, however, that Tenant shall not remove any existing improvements or 
installations nor make any structural alterations in or to the walls, roof, 
floor or foundation of the leased premises or additions thereto without 
Landlord's prior written consent.

        All such alterations, improvements, installations and additions shall 
immediately become the property of Landlord subject to the rights of Tenant 
hereunder. The cost of any such change, alterations or constructions shall be 
paid in cash or its equivalent, so that the leased premises shall at all times 
be free of liens for labor, materials supplied or claimed to have been supplied 
to the leased premises. Tenant shall have the right to contest the validity of 
any lien filed as a result of its occupancy at its sole expense.

                                      -4-

 
     All business equipment, machinery and trade fixtures installed by Tenant 
shall remain the personal property of Tenant and may be removed by it upon 
termination or cancellation of this lease, or any extension thereof, or at any 
time prior thereto; provided, however, that any material damage caused by such 
removal shall be repaired, and the leased premises restored to substantially the
same condition as before installation of the items removed, normal wear and tear
excepted, by Tenant at its expense.

     Tenant shall, throughout the term of this lease, and, except as 
specifically herein otherwise provided, at Tenant's sole cost and expense, take 
good care of and maintain in good order and repair the leased premises. Tenant 
shall not commit or suffer to be committed any waste upon or about the same, and
shall promptly, as its own cost and expense except as set forth herein, make all
necessary repairs to the leased premises and appurtenances thereto, whether 
interior or exterior, ordinary or extraordinary, and foreseen or unforeseen. 
Tenant shall, at its own cost and expense, keep the leased premises free and 
clear from all rubbish, dirt, ice, snow, goods or other obstacles. Landlord's 
repair and maintenance obligations hereunder shall be limited to the following:

              (a)  Landlord shall take good care of and maintain the roof and 
     the exterior walls and foundation of the building comprising part of the
     leased premises; provided, however, Tenant shall be responsible for repairs
     to the roof and the exterior walls and foundation to the extent such
     repairs are necessary due to the fault or negligence of anyone other than
     Landlord; and

              (b)  After the two air rotation furnaces (located in the existing
     pit area at the northeast area of the building) have been moved and
     properly reinstalled in good working order by Tenant, Landlord shall then
     reimburse Tenant for any costs in excess of $2,000 for each individual
     repair required to be made to each such furnace, such reimbursement to be
     made promptly after Tenant sends Landlord a paid invoice for each such
     repair from a third party repair service. If Tenant determines that either
     or both of such furnaces need to be replaced during the lease term then
     Tenant shall, at its sole cost and expense, replace such furnace or
     furnaces with a furnace or furnaces whose type and size are mutually agreed
     upon by Landlord and Tenant. Landlord agrees to reimburse Tenant for the
     unamortized cost of such new furnace or furnaces

                                      -5-

 
         within thirty (30) days after the normal expiration of the lease term
         or any renewal thereof. Landlord shall have no such reimbursement
         obligation if this lease or Tenant's possession of the leased premises
         is terminated due to a default by Tenant under the terms of this lease
         or if Tenant purchases the leased premises from Landlord. For purposes
         of determining such unamortized cost, the cost of such new furnace or
         furnaces shall be amortized over a twenty year period with no interest.
         For example, if Tenant installs one such new furnace at a cost of
         $10,000 at the end of the fourth month of the initial term of the lease
         and the lease term expires at the end of the initial term (i.e., one
                                                                    ---
         year after installation of the new furnace) without Tenant having
         elected to renew the term, then Landlord shall reimburse Tenant for
         $9,500 of the cost of such new furnace ($10,000 cost divided by 20
         years equals $500 per year amortization multiplied by 1 year,
         subtracted from the original $10,000 cost).

(S)9.  INTENTIONALLY OMITTED.
       ---------------------

(S)10. MECHANIC'S LIENS. Landlord shall not be liable for any labor or materials
       ----------------
furnished to Tenant. Tenant shall not permit any mechanic's or other liens for
such labor and materials to attach to or affect Landlord's interest in the
Premises. Tenant hereby agrees to pay, discharge by bond or deposit or to
successfully defend against any such liens, and failing to do so, Landlord may,
upon giving ten (10) days written notice to Tenant, pay or discharge the same
and the amount so paid or deposited, together with interest at the rate of ten
percent (10%) per annum, shall be deemed additional rent due hereunder and
payable with the next month's base rent.

(S)11. INDEMNITY AND INSURANCE. A. Tenant shall indemnify Landlord for, defend
       -----------------------
Landlord against, and save Landlord harmless from any liability, loss, cost, 
injury, damage, or other expense that may occur or be claimed by or with respect
to any person or property on or about the leased premises resulting from the 
use, misuse, occupancy, possession, or unoccupancy of the leased premises by 
Tenant, its agents, employees, licensees, invitees or guests, or from the 
condition of same. Tenant shall, at its own cost and expense, defend against any
and all such accidents, claims and demands and shall indemnify Landlord for all 
costs and expenses it may incur in connection therewith, Landlord shall not have
any

                                      -6-

 
liability for any loss, cost, injury or damage to the leased premises, to Tenant
or Tenant's employees, agents, licensees, invitees, or guests or to any property
of such persons and Landlord shall not be responsible or liable for loss or 
damage to the contents of the leased premises, regardless of who owns the 
contents and regardless of how or by whom the loss or damage is caused, unless 
same was due to the gross negligence of Landlord.

        B. Tenant agrees to maintain in full force and effect at its sole cost 
and expense throughout the term of this lease (and any renewals), policies of 
fire insurance, including broad forms perils coverage, on the leased premises.
Such insurance shall name Landlord and any mortgagee as loss payees and shall at
all times be in an amount equal to the replacement value of the leased premises,
which value may be redetermined by Landlord from time to time but no more often
than every three (3) years. It shall be the responsibility of Landlord to give
Tenant written notice of such redetermined value, the obligations of Tenant
hereunder being limited to the amount stated in the written notice last received
by Tenant. A certificate of the insurance (or copy of the policy if requested by
Landlord or its mortgagee) required under this section shall be delivered to
Landlord at least fifteen (15) days prior to the time such insurance is required
to be carried by Tenant, and thereafter at least fifteen (15) days prior to the
expiration of any such policies. Such insurance shall be written by a company or
companies rated A or A+ by Best's Insurance Guide, with a ten (10) or better
financial rating, authorized to engage in the business of fire and extended
coverage insurance in the State of New York and reasonably acceptable to
Landlord and any mortgagee. Such policies of insurance obtained pursuant to the
provisions hereof shall contain a provision that no act or omission of Tenant
shall affect or limit the obligation of the insurance company to pay to Landlord
or its mortgagee the amount of any loss sustained and shall bear an endorsement
stating that the insuer agrees to notify Landlord in writing by certified mail
not less than twenty (20) days in advance of any modification, cancellation, or
termination thereof.

        The insurance required hereunder may, at the option of Tenant, be 
effected by blanket and/or umbrella policy or policies issued to Tenant covering
the building and other properties owned or leased by Tenant and/or its 
affiliated entities, and, in the event that the insurance required by this lease
shall be effected by any such blanket or umbrella policy or policies, Tenant 
shall furnish to Landlord a certificate or certificates of such policy or

                                      -7-

 
policies with a statement of value thereto attached showing the amount of 
insurance afforded by such policy or policies directly applicable to the 
building leased by Landlord under this lease.

        If Tenant fails to comply with the requirements of this subsection, 
Landlord may (but shall not be obligated to) obtain such insurance and keep the 
same in effect and Tenant shall pay Landlord the premium cost thereof, as 
additional rent, upon demand with interest at ten percent (10%) per annum until 
paid. The parties agree that the replacement value as of April 1, 1994 for 
purposes of this section shall be equal to $1,800,000.

        C. Tenant, at its own cost and expense, shall procure and maintain in
full force and effect general liability insurance against any and all claims for
personal and bodily injury to persons or damage to property occurring in, on or
about the leased premises during the term of this lease and any renewals
thereof, if exercised. Such insurance shall be written on the occurrence basis
and shall name Landlord and any mortgagee as additional insureds and shall at
all times be in an amount not less than One Million Dollars ($1,000,000) in
respect to personal or bodily injury to or death of one (1) person as a result
of any one (1) occurrence, Three Million Dollars ($3,000,000) in respect to
personal or bodily injuries to or death of more than one (1) person as a result
of any one (1) occurrence, and Five Hundred Thousand Dollars ($500,000) for
property damage as a result any one (1) occurrence. Such insurance shall be
written by a company or companies rated A or A+ by Best's Insurance Guide with a
ten (10) or better financial rating, authorized to engage in the business of
general liability insurance in the State of New York and reasonably acceptable
to Landlord and any mortgagee. A certificate of all such policies (or a copy of
the policies themselves, if requested by Landlord or its mortgagee) procured by
Tenant in compliance herewith shall be delivered to Landlord at least fifteen
(15) days prior to the time such insurance is required to be carried by Tenant
and thereafter at least fifteen (15) days prior to the expiration of any such
policy. Such policy shall bear an endorsement stating that the insurer agrees to
notify Landlord by certified mail not less than twenty (20) days in advance of
any modification, cancellation, or termination thereof.

        If Tenant fails to comply with the requirements of this subsection, 
Landlord may (but shall not be obligated to) obtain such insurance and keep the 
same in effect and

                                      -8-

 
Tenant shall pay Landlord the premium cost thereof, as additional rent, upon 
demand with interest at ten (10%) per annum until paid.

        D.  Tenant shall carry workers' compensation and employer's liability
insurance in amounts of not less than that required by applicable law.

(S)12.  WAIVER OF SUBROGATION.  Tenant hereby releases Landlord from any and all
        ---------------------
liability or responsibility to Tenant or anyone claiming through or under Tenant
by way of subrogation or otherwise for any loss or damage specifically insured 
against, or required by the terms of this lease to be insured against, by
Tenant, even if such loss or damage shall have been caused by the fault or
negligence of Landlord or anyone for whom Landlord may be responsible, and
Tenant agrees to cause its insurance policies to contain a clause pursuant to
which the insurance company or companies (a) waive the right of subrogation
against Landlord for losses covered by such policies and (b) agree that such
policies shall not be invalidated because Tenant has hereby waived any right of
recovery for losses covered by such policies.

(S)13.  PERSONAL PROPERTY.  Landlord shall not be liable for any loss or damage 
        -----------------
to any personal property of Tenant or of anyone claiming by or through Tenant 
including any loss or damage resulting from burst, stopped or leaking water or 
sewer pipes, or from electrical wiring, equipment and fixtures, unless same was 
due to the gross negligence of Landlord.

(S)14.  DESTRUCTION OF PREMISES.  In the event of any damage or destruction to 
        -----------------------
improvements on the leased premises, Tenant shall forthwith repair, restore or
replace the damaged or destroyed improvements, and complete the same as soon as 
reasonably possible to the condition they were in prior to such damage or 
destruction, except for such changes in design or materials as may then be 
required by law.  Landlord, in such event, shall, to the extent and at the times
the insurer and Landlord's mortgagee make the proceeds of the insurance 
available for such purposes, reimburse Tenant for the costs of making such 
repairs, restoration, rebuilding and replacements; provided, further, that said 
reimbursements need be made only under such conditions that Landlord and its 
mortgagee are assured that at all times the leased premises shall be free of 
liens or claims of liens by reason of such work; and, provided, further, that
the portion of the proceeds paid out at any time shall not exceed the value of
the actual work and materials incorporated in the repaired, restored, rebuilt or
replaced premises. To the extent, if any, that the proceeds of insurance made
available for

                                      -9-





 
such purposes are insufficient to pay the entire costs of making such repairs, 
restoration, rebuilding and replacements, Tenant shall bear such costs.  The 
obligation to pay the rent provided in this lease shall continue unabated by 
reason of any such damage or destruction, that is, there shall be no abatement 
or diminution of rent by reason of such damage or destruction regardless of the
period of time, if any, during which the leased premises or any part thereof 
remain untenantable.

        In the event of any loss or destruction on the leased premises, Tenant 
shall promptly notify Landlord and its mortgagee and shall make prompt proof of 
loss to the relevant insurance company or companies involved.

(S)15.  CONDEMNATION.  A. In the event that at any time during the continuance
        ------------
of this lease, title shall be taken to over five percent (5%) of the square
footage of the building or five (5%) of the parking lot of the leased premises,
by the exercise of the right of condemnation or eminent domain or by agreement
between Landlord and those authorized to exercise such right this lease shall
terminate and expire on the date of such taking and the rent provided to be paid
by Tenant shall be apportioned and paid to the date of such taking. In the event
of any such taking Landlord shall be entitled to all damages, consequential 
damages, and compensation for such taking and Tenant shall not be entitled to
share in any such award nor have any claim against Landlord for any part
thereof; provided, however, if the laws then in effect permit a separate award
to Tenant for any or all of its losses, nothing contained herein shall prevent
or prohibit Tenant from seeking and obtaining such separate award.

        B.  In the event of any taking other than as provided in subparagraph A,
above, this lease shall continue unaffected, and, except as hereinafter 
specifically otherwise provided, Landlord shall be entitled to all damages, 
consequential damages and compensation for such taking and Tenant shall not be 
entitled to share in any such award or have any claim against Landlord for any 
part thereof, except as provided in subparagraph A. above; provided, however, 
that Landlord shall, to the extent the net proceeds of such award are made 
available to it and to the extent Landlord's mortgagee, if any, does not require
the same to be applied upon the mortgage indebtedness, reimburse Tenant for its 
costs of demolition, repair and restoration to return the leased premises to a 
tenantable condition.  Tenant shall promptly upon any such partial taking make 
such demolitions, repairs and

                                     -10-

 
restorations as are necessary to return the leased premises to a tenantable
condition and, in the event that the cost of such demolition, repairs and
restoration shall exceed the then amount collected by Landlord, Tenant
shall pay the deficiency.

(S)16.  UTILITIES.  Tenant shall furnish, at its own expense, trash removal,
        ---------
all utilities of every type and nature required by it in its use of the leased
premises and shall pay or cause to be paid, when due, all bills for water,
sewage, gas and electricity used on, in connection with, or chargeable
against the leased premises until the termination of this lease; and Tenant
shall indemnify and save harmless Landlord from and against any loss, cost
and expense in connection therewith.

(S)17.  PROTECTION OF LANDLORD'S MORTGAGE.  A.  This lease shall be subject and
        ---------------------------------
subordinate to any mortgages that may have been placed or may be hereafter
placed upon the leased premises by Landlord, and to any advances to be made
thereunder, and to all renewals, replacements, and extensions thereof; 
provided, however, that any mortgagee may elect by written notification to 
Tenant to give the rights and interest of Tenant under this lease priority
over the lien of its mortgage.  However, Tenant's obligations to so
subordinate to any such mortgagee shall be conditioned upon Tenant's receipt
of an acceptable non-disturbance agreement from such mortgagee.

      B.  Although this (S)17 is self-executing, Tenant shall execute and
deliver whatever instruments may be required by Landlord's mortgagee, within
ten (10) days of written notice by such mortgagee, for the purposes of 
evidencing the subordination of this lease or making this lease superior.
Failure by Tenant to execute such instruments shall constitute an irrevocable
appointment by Tenant of Landlord as its attorney-in-fact for the purpose
of executing such instruments.

      C.  At Landlord's written request, Tenant shall furnish to Landlord 
within one hundred twenty (120) days following the end of each fiscal year
during the term of this lease, beginning in 1994, and at such other times 
as Landlord may request, but not more often than semi-annually, a copy of
Tenant's current financial statements, including balance sheets and income
statements, such statements to be prepared in accordance with generally 
accepted accounting principles consistently applied.  Such statements shall
be certified by an independent certified public accountant or by Tenant's
chief financial officer.  Such financial statements shall be received and
held by Landlord on a strictly confidential basis; provided,



                                     -11-

 
however, that Landlord may disclose such financial statements to 
prospective mortgagees or purchasers of the Premises.

      D.  At any time and from time to time, Tenant agrees, upon request
in writing from Landlord, to promptly execute, acknowledge and deliver to
Landlord or to the holder of any mortgage on the leased premises a 
statement, in form and substance satisfactory to Landlord, certifying, if
true, (i) that this lease is unmodified and in full force and effect (or if
there have been modifications, that the same is in force and effect as 
modified and stating the modifications), (ii) that there are no defaults
of Landlord hereunder (or if same exists, a statement indicating same), (iii)
the dates to which the base rent, additional rent and other charges have been
paid and (iv) that Tenant has accepted possession of the leased premises and
the term of the lease has commenced, giving the date of such commencement.
If Tenant fails to provide such a statement within ten (10) days after 
written request therefore, Tenant does hereby make, constitute and irrevocably
appoint Landlord or any such mortgagee as its attorney-in-fact and in its
name, place and stead so to do.

(S)18.  LIMITATION OF LIABILITY.  Tenant specifically agrees to look solely
        ------------------------
to Landlord's interest in the premises for the recovery of any judgment 
Tenant may obtain against Landlord, it being agreed that neither Landlord
nor any of its partners shall ever be personally liable for any such
judgment.  Landlord will, however, carry at all times during the lease term
at least $3,000,000.00 of liability insurance and give Tenant, upon request,
proof of payment thereof.

(S)19.  TRANSFER OF LANDLORD'S INTEREST.  If Landlord should sell or otherwise
        --------------------------------
transfer its interest in the leased premises upon an undertaking by the
purchaser or transferee to be responsible for all of the covenants and 
undertakings of Landlord, Tenant agrees that Landlord shall thereafter have
no liability to Tenant under this lease or any modifications or amendments
thereof, or extensions thereof, except for such liabilities which might have
accrued prior to the date of such sale or transfer of its interest by Landlord.

(S)20.  SEVERABILITY OF PROVISIONS.  The invalidity or unenforceability of any
        ---------------------------
particular provision of this lease shall not affect the other provisions
hereof and this lease shall be construed in all respects as if such invalid
or unenforceable provision were omitted; provided that, in lieu of such
invalid or unenforceable provisions, there shall be added

                                     -12-

 
automatically as part of this lease a provision as similar in terms to such
illegal, invalid or unenforceable provisions as may be possible and 
as may be legal, valid or enforceable.

(S)21.  NON-WAIVER.  Neither a failure by Landlord to exercise any of its
        ----------
options hereunder, nor failure to enforce its right or seek its remedies 
upon any default, nor the acceptance by Landlord of any rent accruing before 
or after any default, shall effect or constitute a waiver of Landlord's right
to exercise such option, to enforce such rights, or to seek such remedy with
respect to that default or to any prior or subsequent default.  The remedies
provided in this lease shall be cumulative and shall not in any way abridge,
modify or preclude any other rights or remedies to which Landlord is entitled
either by law or in equity.

(S)22.  ENJOYMENT WITHOUT MOLESTATION.  If Tenant pays the rent it is obligated
        ------------------------------
hereunder to pay, and observes all other terms, covenants and conditions hereof,
it shall occupy and enjoy the use of the leased premises during the continuance
hereof, without any hindrance, molestation, or ejection by Landlord, its
successors or assigns.

(S)23.  SUCCESSORS IN INTEREST ASSIGNMENT.  Tenant shall not assign or sublet;
        ----------------------------------
the leased premises except to affiliates or subsidiaries or except through
the transfer of a majority interest in the stock of Tenant or a merger of
Tenant, without the prior written consent of Landlord, which consent will
not be unreasonably withheld.  No assignment of this lease, whether by act 
of Tenant or by operation of law, and no sublease by or from Tenant, shall
relieve or release Tenant from any of its obligations hereunder.  Landlord
shall have the right to cancel this lease upon any assignment made or 
attempted to be made to an unaffiliated assignee of Tenant or any assignment
not approved by Landlord, for any reason.  In the event of such cancellation
Tenant will be released from any further obligations hereunder.

(S)24.  ENTRY BY LANDLORD.  Landlord and its duly authorized representatives
        -----------------
shall have the right to enter the leased premises at all reasonable times
with forty-eight (48) hours prior notice (except in emergencies and as set
forth below) for the purposes of (a) inspecting the condition of same and
making such repairs, alterations, additions or improvements thereto as may
be necessary or desirable (but Landlord shall have no duty to make any such
repairs, alterations, additions or improvements), and (b) exhibiting the same 
to persons who may wish to purchase or lease the same, and during the last
three (3) months of the term of this

                                     -13-

 
lease and any renewal term, placing any notice of reasonable size on the leased 
premises offering the same or any part thereof for sale or rent; provided, 
however, in no event shall Landlord unreasonably interfere with Tenant's use of 
the leased premises. In addition, Landlord, the previous tenant of the leased 
premises, the New York Department of Environmental Conservation and their 
authorized representatives shall have access to the former exterior sites of the
underground fuel oil tanks at all reasonable times without prior notice in order
to complete the remediation of the soils around such sites; provided, however, 
in no event shall any of such parties unreasonably interfere with Tenant's use
of the leased premises.

(S)25.  DEFAULT. If Tenant fails to pay any installments of base rent or make 
        -------
any payment of additional rent or fails to supply evidence of any insurance
required by the terms hereof, within ten (10) days after it becomes due
hereunder and after written demand has been made therefor, or if Tenant fails to
observe and perform any other provision, covenant or condition of this lease
required under this lease to be observed and performed by Tenant, within thirty
(30) days after Landlord shall have given written notice to Tenant of the
failure of Tenant to observe and perform the same, and if Tenant fails to
proceed timely and promptly with all due diligence and in good faith to the
curing of such default, or if Tenant abandons the leased premises, or any part
thereof, during the continuance of this lease, or if Tenant makes any assignment
for the benefit of creditors or enters into a composition agreement with its
creditors, or if the interest of Tenant in the leased premises is attached,
levied upon, or seized by legal process, or if a bankruptcy or insolvency
proceeding is filed by or against Tenant, or if a court of competent
jurisdiction or other governmental authority approves a petition seeking
reorganization, arrangement, composition or similar relief with respect to
Tenant, or appoints a trustee, receiver or liquidator of Tenant of all, or
substantially all of its property or affairs, or assumes custody or control of
all, or substantially all, of the property or affairs of Tenant, or if this
lease is assigned in violation of the terms hereof, or is terminated by
operation of law, then and in any such event, immediately or at any time
thereafter, at the option of Landlord, Landlord shall have the right to
immediately re-enter and take possession of the leased premises, and, as it
elects, either (a) declare this lease to be terminated, in which event this
lease, all rights of Tenant, and all duties of Landlord shall immediately cease
and terminate, and Landlord may possess and enjoy the leased premises as

                                     -14-

 
though this lease had never been made, without prejudice, however, to any and 
all rights of action against Tenant which Landlord may have for rent, damages or
breach of covenant, in respect to which Tenant shall remain and continue liable 
notwithstanding such termination, or (b) relet the leased premises, or any part 
thereof, for such term or terms and on such conditions, as Landlord determines 
for and on behalf of Tenant for the highest rental reasonably obtainable in the 
judgment of Landlord, which reletting shall not be considered as a surrender or 
acceptance back of the leased premises or a termination of this lease and, 
recover from Tenant any deficiency between the amount of rent, additional rent 
and all other charges payable under this lease, plus any expenses incurred by 
Landlord in connection with such reletting, including, without limitation, the 
reasonable expenses of any redecorating or repairs Landlord deems necessary or 
appropriate to make in connection with such re-letting and sums expended for 
brokerage commissions and reasonable attorney's fees; but the Landlord shall be 
under no duty to relet the leased premises.

        In the event that Tenant fails to pay by its respective due dates all 
charges and other obligations to be paid by it pursuant to the terms hereof, or
fails to make necessary repairs to the leased premises as required by this 
lease, or fails to restore to its former state any damaged or destroyed portion 
hereof, or fails to carry insurance as provided herein, then Landlord, at its 
option, may do so and the amount of such expenditure, plus accrued interest at 
the rate of ten percent (10%) per annum from the time each such expenditure is 
made until reimbursed, shall immediately become due and payable to Landlord and 
be considered additional rent hereunder, but no such payment or compliance by 
Landlord shall constitute a waiver of any such failure by Tenant or affect any 
right or remedy of Landlord with respect thereto. In addition, a late charge 
shall be assessed as additional rent in the amount of three percent (3%) of the 
amount due for any rental payment received after the tenth of any lease month.

(S)26.  SURRENDER OF PREMISES. Upon termination of this lease, whether by lapse 
        ---------------------
of time or otherwise, or upon the exercise by Landlord of the power to re-enter 
and repossess the leased premises without terminating this lease, as 
hereinbefore provided, Tenant shall at once surrender the possession of the same
to Landlord in good order and repair, ordinary wear and tear excepted, and at 
once remove all of Tenant's property therefrom. If, upon such an event, Tenant 
does not at once surrender possession of the same and remove all its

                                     -15-

 
property therefrom, Landlord may forthwith re-enter and repossess the same and 
remove all of Tenant's property therefrom and store the same without being 
guilty of trespass or of forcible entry or detainer without incurring liability 
to Tenant for loss or damage to the Tenant's property, and thereafter, Landlord 
may recover from Tenant all reasonable costs and expenses incurred by Landlord 
in removing Tenant's property and storing the same, together with interest as 
aforesaid.

(S)27.  HOLDING OVER BY TENANT. If Tenant shall continue in possession of the 
        ----------------------
leased premises beyond the termination of the term hereof, such holding over 
shall be considered an extension of this lease for a one month period, and so on
from month to month, until terminated by either party giving not less than 
thirty (30) days' written notice of termination. Such month-to-month extension 
shall be on the same terms and conditions set forth herein except that the base 
rent payable hereunder shall be equal to twice the amount of the base rent for 
the immediately preceding term, unless Landlord and Tenant are in active 
discussions for a new lease agreement or Tenant has contracted to purchase the 
leased premises. 

(S)28.  REAL ESTATE BROKERS. Tenant represents and warrants that the only 
        -------------------
brokers, agents or other persons it has dealt with in connection with this 
transaction are Moore & Bowles, Inc. and Remax, and Tenant agrees to indemnify, 
defend and hold Landlord harmless from and against any claims by any other 
brokers, agents or other persons claiming a commission or other form of 
compensation by virtue of having dealt with Tenant with regard to this leasing 
transaction. Landlord shall be responsible for all brokerage commissions payable
to Moore & Bowles, Inc. and to Remax as the cooperating broker for Moore & 
Bowles, Inc., in connection with this transaction.

(S)29. TIME OF THE ESSENCE. Time is of the essence in the doing, performance and
       -------------------
observation of each and every term, covenant and condition of this lease by both
Landlord and Tenant.

(S)30.  NOTICE. Any notice, exercise of option or election, communication, 
        ------
request or other document or demand required or desired to be given to Landlord 
or Tenant shall be in writing and shall be deemed given: (a) to Landlord when 
deposited in the United States mail, certified or registered, postage prepaid, 
addressed to Landlord at its address set forth at the beginning hereof, and (b) 
to Tenant when deposited in the United States mail, certified or

                                -16-

 
registered, postage prepaid, addressed to Tenant at its address set forth at the
beginning hereof. Either party may, from time to time, change the address at 
which such written notices, exercises of options or elections, communications, 
requests, or other documents or demands are to be mailed, by giving the other 
party written notice of such changed address.

(S)31.  AMENDMENTS. No amendment of this lease shall be valid or binding unless 
        ----------
such amendment is in writing and executed by both Landlord and Tenant.

(S)32.  SHORT FORM LEASE. The parties shall upon request of Landlord or Tenant 
        ----------------
execute a short form of lease for recording purposes only, in form satisfactory 
to Landlord's counsel. Such short form lease may be recorded by either Landlord 
or Tenant in lieu of recording this lease. This lease shall not be recorded in 
the public records.

(S)33.  GOVERNING LAW. This lease shall be subject to and governed by the laws 
        -------------
of the State of New York.

(S)34.  SUCCESSORS AND ASSIGNS. This lease and the respective rights and 
        ----------------------
obligations of the parties hereto shall inure to the benefit of and be binding 
upon the parties hereto and their respective successors and assigns.

(S)35.  CAPTIONS AND TABLE OF CONTENTS. The captions of the several sections 
        ------------------------------
and the Table of Contents of this lease are not a part of the context hereof and
shall be ignored in construing this lease. They are intended only as aids in
locating and reading the various provisions hereof.

(S)36.  AUTHORITY. Each party represents and warrants to the other that it has 
        ---------
the full capacity and authority to enter into, execute, deliver and perform its 
obligations under this lease.

(S)37.  HAZARDOUS MATERIALS. Tenant covenants and agrees that it shall not 
        -------------------
receive, transport, store, process, manufacture, package, assemble, distribute, 
generate, produce, release, emit or discharge at or from the leased premises any
hazardous material or substances, as defined under the Comprehensive
Environmental Response, Compensation and Liability Act, 42 U.S.C. Sections 9601,
et seq., or any hazardous waste as defined under the Solid Waste Disposal Act,
42 U.S.C. Sections 7401, et seq., or any toxic pollutants as defined under the
Clean Water Act, 33 U.S.C. Sections 1251, et seq or as defined under any other
applicable federal, state or local law, rule, ordinance or regulation
("Hazardous Materials or Substances"), or cause any contamination to the leased
premises arising out of
                                -17-

 
the presence of any Hazardous Material or Substances. However, the term 
"Hazardous Materials or Substances" shall not apply to items that are used in 
the normal course of Tenant's business, provided that such items are used, 
handled, transported and stored in strict compliance with any and all applicable
federal, state and local laws, rules, regulations, codes, ordinances and 
requirements. Tenant agrees to indemnify and hold Landlord harmless for any 
damages, losses, fines, penalties, costs and expenses, including reasonable 
attorney's fees and expenses (including court and administrative costs), 
incurred by or arising out of any claim for bodily injury (including death), 
property damage, contamination of or adverse effects on the environment as a 
reasonable result of Tenant's breach of any of the covenants contained in this 
paragraph, and further agrees that the provisions of this paragraph shall 
survive the termination of this lease or any extension thereof. Landlord agrees 
to remove or encapsulate the asbestos, if any, now existing at the leased 
premises if Landlord is specifically ordered to do so by any governmental agency
having jurisdiction thereover.

        If, after the Commencement Date, there is any spill, contamination, 
discharge, leakage, the release or escape of any Hazardous Material or Substance
upon or affecting the leased premises, whether sudden or gradual, accidental or 
anticipated, or of any other nature (hereinafter "Spill"), Tenant shall 
immediately give Landlord written notice thereof and shall take all steps 
necessary to clean up such Spill and any contamination related to the Spill and 
to restore the leased premises to substantially the same condition and utility 
that existed prior to the Spill, all in accordance with the requirements, rules 
and regulations of any state or federal environmental department or agency 
having jurisdiction over the Spill and Tenant shall allow Landlord or its agents
or any state or federal environmental department or agency having jurisdiction 
thereof to monitor and inspect all clean-up and restoration related to such 
Spill at the sole cost and expense of Tenant.

(S)38.  ATTORNEY'S FEES. In the event Tenant defaults in the performance of any 
        ---------------
of the material terms, covenants, agreements or conditions contained in this 
lease and Landlord places the enforcement of this lease, or any part thereof, or
the collection of any rent due or to become due hereunder, or recovery of 
possession of the leased premises in the hands of outside legal counsel, or 
files suit upon the same, Tenant agrees to pay Landlord reasonable attorneys' 
fees and costs whether or not suit is instituted. If suit is instituted and 
Landlord substantially prevails in such action, Tenant agrees to pay Landlord's 
reasonable attorneys

                                -18-

 
fees and costs incurred at the trial level and at all levels of appeal.  If 
Tenant substantially prevails in such action, Landlord agrees to pay Tenant the 
reasonable cost of its outside legal counsel and costs incurred at the trial 
level and at all levels of appeal.

(S)39.  CUMULATIVE RIGHTS AND REMEDIES.  All rights and remedies of Landlord or 
        ------------------------------    
Tenant under this Lease shall be cumulative and none shall exclude any other 
rights or remedies allowed by law.

(S)40. ENTIRE AGREEMENT.  Landlord and Tenant acknowledge and agree that all 
       ----------------
promises, warranties and agreements with respect to this lease, the leased 
premises and the relationship between Landlord and Tenant are in writing.  This 
Lease may be executed in any number of counterparts, each of which shall be an 
original, but all of which shall constitute one instrument.

(S)41.  BANK WAIVER.  Landlord shall execute simultaneously with the execution
        -----------
of this lease, a bank waiver as herein attached acknowledging Tenant's financial
institution's interest and right with respect to Tenant's inventory kept at the
leased premises.

             IN WITNESS WHEREOF, Landlord and Tenant have caused this lease to
be duly executed and delivered on the day and year aforesaid.
