Hundred Eighty-Seven Dollars and Twenty-Nine Cents ($2,987.29) for each month.
Each monthly installment shall be paid in advance on the FIRST DAY of each and
every calendar month during the term hereof. If the term of this lease shall
begin on a day other than the 1st of a month, the Lessee shall pay a PRO RATA
portion of a month's rent on the day the term commences and thereafter the

         3.2      Any payment by Lessee or acceptance by Lessor of a lesser
amount than shall be due from Lessee to Lessor shall be treated as a payment on
account. The acceptance by Lessor of a check or payment for a lesser amount with
an endorsement or statement thereon, or upon any letter accompanying such a
check or payment, that such lesser amount is payment in full, shall be given no

other rights or remedies which Lessor may have against Lessee.

         3.3      Lessee covenants and agrees to pay Lessor at the place

being 19.626% of the charges, costs and expenses defined in paragraphs 6.3, 7.2,
10.1 and 19.1 of this Lease. Lessee shall pay Lessor such additional rent in

additional rent in monthly installments shall be One Thousand Six Hundred Eight
Dollars and Fifty-Four Cents ($1,608.54) until notification of further
adjustment in accordance with this Lease. In addition to the foregoing, Lessor

Eighty-Seven Dollars and Twenty-Nine Cents ($2,987.29) with the Lessor, the
receipt of which is hereby acknowledged, as security for the full and faithful
performance by the Lessee of each and every term, covenant and condition of this
Lease. Lessee shall maintain the full amount of the security deposit throughout
the term of this Lease. In the event that the Lessee defaults with respect to
any terms, provisions, covenants and conditions of this Lease, including but not
limited to payment of any rentals, the Lessor may use, apply or retain the whole
or any part of the security so deposited for the payment of any such rentals in
default or for any such sums which Lessor may expend or be required to expend by
reason of the Lessee's default, including any damages or deficiency in the
reletting of the Demised Premises, whether such damages or deficiency may accrue
before or after summary proceedings or other reentry by the Lessor. In the event
that the Lessee shall fully and faithfully comply with all terms, provisions,
covenants and conditions of this Lease, the security or the balance thereof will
be returned to the Lessee after the time fixed as the expiration thereof. The
Lessee shall not be entitled to any interest on the security. In the absence of
evidence satisfactory to the Lessor of any assignment of the right to receive
this security, or the remaining balance thereof, the Lessor may return the
security to the original Lessee, regardless of one or more assignments of the
Lease itself.

         Prior to the time when the Lessee shall be entitled to return of the
security deposit, the Lessor shall be entitled to intermingle such deposit with
its own funds and to use such funds for purposes as the Lessor may determine.

         In the event of a bona fide sale, subject to this Lease, the Lessor
shall have the right to transfer the security deposit to the vendee for the
benefit of the Lessee, and the Lessor shall be considered released by the Lessee
from all liability for return of

is hereby defined and agreed as being 19.626% of (a) the real property taxes
upon the land and/or building comprising 20 Industrial Park Drive, Nashua, New
Hampshire and (b) any assessment, betterment charge or other special levy
against or upon such land and building.

         13.2     "Real estate taxes" shall mean all real estate taxes, sewer
taxes and any other charges made by a public authority which upon assessment or
failure of payment become a lien or liens upon the Leased Premises or any part
thereof, or upon any buildings or appurtenances thereto, or any parts thereof,
or which may become due and payable with respect thereto. Real estate taxes
shall not include any franchise, estate, inheritance, succession, capital levy
or transfer tax of Lessor or any income tax of Lessor.

         13.3     Lessee shall automatically pay and discharge all taxes which
shall or may during the term of this Lease be charged, laid, levied or imposed
upon or become a lien upon the personal property of Lessee attached to or used
in connection with Lessee's business conducted on the Leased Premises. Nothing
herein contained shall require Lessee to pay any taxes on the rent reserved to
Lessor hereunder.

         13.4     Lessee shall have the right to contest or review (in the name
of Lessee, or of Lessor, or both, as Lessee shall elect) by appropriate
proceedings which, if instituted, shall be conducted promptly at Lessee's own
expense free of all expense to Lessor, any tax, charge or other governmental
imposition aforementioned upon condition that before instituting any such
proceeding Lessee shall pay (under protest) such tax, charge or other
governmental imposition aforementioned, or furnish to Lessor a surety company
performance bond in a company acceptable to Lessor or other security
satisfactory to Lessor sufficient to cover the amount of the contested item or
items with interest for the period which such proceedings may reasonably be
expected to take and costs securing the payment of such contested item or items
and all interest and costs in connection therewith when finally determined.
Notwithstanding the furnishing of any such bond or security, Lessee shall pay
all such items before the date when the Leased Premises or any part thereof
would, under applicable law, be forfeited. Lessor shall timely file the annual
inventory required by Chapter




                                       11
<PAGE>

74:7 of the Revised Statutes Annotated of New Hampshire, the filing of which, by
virtue of Chapter 76:16 of such Revised Statutes Annotated, is a condition
precedent to tax abatement.

         13.5     Lessor, at its option, may, but shall not be obligated to,
contest or review by any appropriate proceedings, and at Lessor's expense, any
tax, charge or other governmental imposition aforementioned which shall not be
contested or reviewed as aforesaid by Lessee, and unless Lessee shall promptly
join with Lessor in such contest or review, Lessor shall be entitled to receive
and retain any refund payable by the taxing authorities with respect thereto.
The Lessor shall notify the Lessee promptly of the institution of any such
proceedings.

                                   SECTION 14

                                 MECHANIC'S LIEN

         In the event of the filing in the Hillsborough County Registry of Deeds
of any notice of a builder's, supplier's or mechanic's lien on the Leased
Premises arising out of any work performed by or on behalf of Lessee, Lessee
shall cause without delay proper proceedings to be instituted to test the
validity of the lien claimed, and before the end of the term to discharge the
same by the posting of bond or otherwise; and during the pendency of any such
proceeding, Lessee shall completely defend and indemnify Lessor against any such
claim or lien and all costs of such proceedings wherein the validity of such
lien is contested by Lessee, and during the pendency of such proceeding such
lien may continue until disposition of such proceeding, and after disposition
thereof, Lessee shall cause said lien to be released and discharged.

                                   SECTION 15

                                 EMINENT DOMAIN

         In the event that the Leased Premises shall be lawfully condemned or
taken by any public authority either in their entirety or in such proportion
that they are no longer suitable for the intended use by Lessee, this Lease
shall automatically terminate without further act of either party hereto on the
date when possession of the Leased Premises shall be taken by such public
authority, and each party hereto shall be relieved of any further obligation to
the other except that Lessee shall be liable for and shall promptly pay to
Lessor any rent or other payments due hereunder then in arrears or the Lessor
shall promptly rebate to Lessee a PRO RATA portion of any rent or other such
payments paid in advance. In the event the proportion of the Leased Premises so
condemned or taken is such that they are still suitable for the intended use by
Lessee, this Lease shall continue in effect in




                                       12
<PAGE>

accordance with its terms and a portion of the rent and other payments due
hereunder shall abate equal to the proportion of the rental value of the Leased
Premises so condemned or taken. In either of the above events, the award for the
property so condemned or taken shall be payable solely to Lessor except that if
the property so condemned or taken includes in whole or in part (a) the land
thereon at the beginning of the term hereof and (b) machinery, equipment and
appurtenances constructed or installed thereon by Lessee at its expense after
the beginning of the term hereof which would have been removable by Lessee
pursuant to Section 21 hereof, then such award shall be apportioned between
Lessor and Lessee in accordance with the then relative values of the property
described in clause (a) and clause (b) above, so condemned or taken.

                                   SECTION 16

                                    LIABILITY

         Except for injury or damage caused by the willful act of Lessor, its
servants or agents, Lessor shall not be liable for any injury or damage to any
person happening on or about the Leased Premises or for any injury or damage to
the Leased Premises or to any property of Lessee or to any property of any third
person, firm, association or corporation on or about the Leased Premises. The
Lessee shall, except for injury or damage caused as aforesaid, defend, indemnify
and save the Lessor harmless from and against any and all liability and damages,
costs and expenses, including reasonable attorney's fees, and from and against
any and all suits, claims and demands of any kind or nature whatsoever, by and
on behalf of any person, firm, association or corporation arising out of or
based upon any incident, occurrence, injury or damage which shall or may happen
on or about the Leased Premises and from and against any matter or thing growing
out of the condition, maintenance, repair, alteration, use, occupation or
operation of the Leased Premises or the installation of any property therein or
the removal of any property therefrom.

                                   SECTION 17

                               LIABILITY INSURANCE

         Lessee shall, from the date on which it takes possession of the Leased
Premises even if such date precedes the commencement of the term hereof and
throughout the term hereof procure and carry at its expense comprehensive
liability insurance on the Leased Premises with an insurance company authorized
to do business in New Hampshire and acceptable to Lessor. Such insurance shall
be carried in the name of and for the benefit of Lessee and Lessor; shall be
written on an "occurrence" basis; and shall provide coverage of at lease One
Million Dollars ($1,000,000) in case of death of or injury to one person, Two
Million Dollars ($2,000,000)


                                       13
<PAGE>


in case of death of or injury to more than one person in the same occurrence,
and One Hundred Thousand Dollars ($100,000) in case of loss, destruction or
damage to property. If applicable, Lessee shall comply with the requirements of
the Boilers and Unfired Pressure Vessels Law (RSA 157-A), and in such event the
policy or policies referred to above shall contain an endorsement providing
pressure vessels insurance coverage and naming Lessor as an additional insured.
Lessee shall furnish to Lessor a certificate of such insurance which shall
provide that the insurance indicated therein shall not be cancelled without at
least ten (10) days' written notice to Lessor. At the end of the first term of
this Lease and every three (3) years thereafter, Lessee shall increase the
insurance coverages provided herein if requested to do so by Lessor to such
amounts which are then adequate to protect against increases in insurance awards
whether caused by inflation or otherwise. Lessee shall also maintain insurance
for all glass and all signs installed in the Leased Premises.


                                   SECTION 18

                            BUILDER'S RISK INSURANCE

         During any period or periods of construction by Lessee on the Leased
Premises, the construction of which (a) is of a type to which Builder's Risk
insurance is applicable and (b) requires the advance written approval of Lessor
pursuant to Section 8(F) hereof, Lessee shall obtain and maintain in effect
standard Builder's Risk insurance written on a completed value basis, including
extended coverage, and utilizing a maximum value at date of completion not less
than the greater of (a) the aggregate contract price or prices for the
construction of such facilities or (b) the amount which may be required by a
mortgagee which is financing such construction. Such insurance shall be obtained
from an insurance company authorized to do business in New Hampshire and
acceptable to Lessor, and there shall be furnished to Lessor a certificate of
such insurance which shall provide that the insurance indicated therein shall
not be cancelled without at least ten (10) days' written notice to Lessor. If
such construction by Lessee is of a type to which Builder's Risk insurance is
not applicable, Lessee shall provide the necessary additional coverage under the
policies referred to herein.

                                   SECTION 19

                         SPECIAL FORM PROPERTY INSURANCE

         19.1     Lessor shall procure and continue in force during the term
hereof Special Form Property insurance upon the facilities constructed, erected
or installed on the Leased Premises by Lessor on a full value, repair or
replacement basis. In accordance with




                                       14
<PAGE>

paragraph 3.3 of this Lease, Lessee shall reimburse Lessor for Lessee's pro RATA
share of the premiums paid for such insurance as additional rent.

         19.2     During the term hereof, Lessee shall procure and continue in
force insurance which contains all risk coverage on a full value, repair or
replacement basis upon machinery, equipment and appurtenances constructed ,
erected or installed on or in the Leased Premises by Lessee and which have or
may be the property of Lessor pursuant hereto. The policies evidencing such
insurance shall provide that loss, if any, payable thereunder shall be payable
to Lessor and/or Lessee and/or mortgagee of the Leased Premises as their
respective interests may appear, and all such policies together with evidence of
payment of the premiums thereon shall be delivered to Lessor and/or any such
mortgagee. All such policies shall be taken in such responsible companies
authorized to do business in New Hampshire as Lessor shall approve (which
approval shall not be unreasonably withheld) and shall be in form satisfactory
to the Lessor. Upon receipt of a copy of notice of cancellation of any insurance
which is the responsibility of Lessee hereunder, Lessor may pay the premiums
necessary to reinstate the same. The amount so paid shall constitute additional
rent payable by Lessee at the next rental payment date. Payment of premiums by
Lessor shall not be deemed a waiver or release by Lessor of the default by
Lessee in failing to pay the same or of any action which Lessor may take
hereunder as a result of such default. Lessee shall not violate, nor permit any
person, firm, association or corporation to violate, any of the terms,
conditions and provisions of such policies. In the event of loss, Lessor shall
promptly initiate action to effect a settlement with the insurer, Lessee shall
cooperate with Lessor and any mortgagee in connection with the proceeding and
collection of claims, and shall execute and deliver to Lessor such proofs of
loss, releases and other instruments as may be necessary to settle any such
claims and obtain the proceeds thereof, and in the event Lessee shall fail or
neglect so to cooperate or to execute and deliver any such instrument Lessor
may, as the agent or attorney in fact of Lessee, execute and deliver any such
instrument, and Lessee here by nominates and appoints Lessor the proper and
legal attorney in fact of Lessee for such purpose, hereby ratifying all that
Lessor may lawfully do as such attorney in fact.

         19.3     If and to the extent permitted without prejudice to any rights
of Lessor under the applicable insurance policies, Lessee shall be held free and
harmless from liability for loss or damage to the Leased Premises by fire, the
extended coverage perils, sprinkler leakage, vandalism and malicious mischief if
and to the extent actually insured against, whether or not such loss or damage
be the result of the negligence of Lessee, its employees or agents. This
subsection does not impose any added obligation or expense upon Lessor nor
require that it carry any insurance of any kind and




                                       15
<PAGE>

is to be construed only as a limitation upon the rights of the insurance
carriers to subrogation.

         19.4     If and to the extent permitted without prejudice to any rights
of the Lessee under the applicable insurance policies, Lessor shall be held free
and harmless from liability for loss or damage to personal property of Lessee in
the Leased Premises by fire, the extended coverage perils, sprinkler leakage,
vandalism and malicious mischief if and to the extent actually insured against,
whether or not such loss or damage be the result of the negligence of Lessor,
their employees or agents. This subsection does not impose any added obligation
or expense upon Lessee nor require that it carry any insurance of any kind and
is to be construed only as a limitation upon the rights of the insurance
carriers to subrogation.

                                   SECTION 20

                              DESTRUCTION OR DAMAGE

         In the event that the Leased Premises shall be totally destroyed by
fire or other casualty insured against, or shall be so damaged that repairs and
restoration cannot, in the opinion of Lessor in its sole discretion, be
accomplished within a period of one hundred twenty (120) days from the date of
such destruction or damage, this Lease shall automatically terminate without
further act of either party hereto, and each party shall be relieved of any
further obligation to the other except for the rights and obligations of the
parties under Sections 18 and 19 hereof, and except that Lessee shall be liable
for and shall promptly pay Lessor any rent then in arrears or Lessor shall
promptly rebate to Lessee a PRO RATA portion of any rent paid in advance. In the
event such facilities shall be so damaged that repairs and restoration can be
accomplished within a period of one hundred twenty (120) days from the date of
such destruction or damage, this Lease shall continue in effect in accordance
with its terms; such repairs and restoration shall, unless otherwise agreed by
Lessor and Lessee, be performed as closely as practicable to the original
specifications (utilizing therefor the proceeds of the insurance applicable
thereto without any apportionment thereof for damages to the leasehold interest
created by this Indenture), and until such repairs and restoration have been
accomplished a portion of the rent shall abate equal to the proportion of the
Leased Premises rendered unusable by the damage. It is understood that Lessor's
obligation to restore, replace or rebuild such facilities shall not exceed in
amount the sum of the insurance proceeds paid to it and/or released to it by any
mortgagee with which settlement was made. Lessee agrees to execute and deliver
to Lessor all instruments and documents necessary to evidence the fact that the
right to such insurance proceeds is vested in Lessor. Lessor shall




                                       16
<PAGE>

notify Lessee within fifteen (15) days of such casualties whether or not the
Lessor will repair the Leased Premises.


                                   SECTION 21

                             REPOSSESSION BY LESSOR

         At the expiration of this Lease or upon the earlier termination of this
Lease for any cause herein provided for, Lessee shall peaceably and quietly quit
the Leased Premises and deliver possession of the same to Lessor together in
good working condition and in a state of repair and readiness for the same use,
with the facilities thereon at the beginning of the term hereof and all
facilities constructed thereon by Lessee which are not removed pursuant to the
terms hereof and all machinery, equipment and appurtenances installed therein
which have become part of the Leased Premises, or which are not to be removed
pursuant to Section 9 hereof. Lessee covenants and agrees that at the time of
delivery of possession to Lessor at the expiration of this Lease any and all
machinery, equipment and appurtenances constructed or installed on or in the
Leased Premises by Lessee at its expense after the beginning of the term hereof
and which have become the property of Lessor pursuant to Section 9 hereof shall
be free and clear of any mortgage, lien, pledge or other encumbrance or charge.


                                   SECTION 22

                                  MORTGAGE LIEN

         Lessee agrees that this Lease and all rights of Lessee hereunder are
and shall be subject and subordinate to the lien of (a) any mortgage or deed of
trust constituting a first lien on the Leased Premises, or any part thereof, at
the date hereof, and (b) the lien of any mortgage or deed of trust hereafter
executed to a person, bank, trust company, insurance company or other recognized
lending institution to provide permanent financing or refinancing of the
facilities on the Leased Premises, and (c) any renewal, modification,
consolidation or extension of any mortgage or deed of trust referred to in
clause (a) or (b), and Lessee shall, upon demand at any time or times, execute,
acknowledge and deliver to Lessor without any expense to the Lessor, any an all
instruments that may be necessary or proper to subordinate this Lease and all
rights of Lessee hereunder to the lien of any mortgage, deed of trust or other
instrument referred to in clause (b) or clause (c) of the preceding sentence;
provided, however, that the subordination of this Lease shall be conditioned
upon the execution and delivery by the mortgagee or trustee of an agreement (i)
that so long as Lessee is not in default under the terms of this Indenture the
mortgagee or trustee, or any person succeeding to the




                                       17
<PAGE>

rights of the mortgagee or trustee, or any purchaser at a foreclosure sale under
said mortgage or deed of trust, shall not disturb the peaceful possession of
Lessee hereunder, and (ii) that the proceeds of insurance policies held by it
will be applied to the cost of repairs and restoration in those instances in
which Lessor is obligated to repair and restore pursuant to the provisions
hereof.


                                   SECTION 23

                                     DEFAULT

         In the event (i) any installment of rent or additional rent shall not
be paid within ten (10) days after it's due date; or (ii) failure to remove snow
and ice from sidewalks, stairs and dock area adjacent to the Leased Premises for
more than 48 hours after such snow or ice appears; or (iii) Lessee defaults in
the performance or observance of any other covenant or condition in this
Indenture and such default remains unremedied for twenty (20) days after written
notice thereof has been given to Lessee by Lessor; or (iv) any warranty or
representation made by Lessee herein proves to be false or misleading; or (v)
Lessee makes an assignment for the benefit of creditors, is generally not paying
its debts as such debts become due, a custodian was appointed or took possession
of its assets other than a trustee, receiver or agent appointed or authorized to
take charge of less than substantially all of the property of Lessee for the
purpose of enforcing a lien against such property, commences any proceeding
relating to Lessee or any substantial part of its property arrangement,
readjustment of debt, dissolution or liquidation law or statute of any
jurisdiction whether now or hereafter in effect, or there is commenced against
Lessee any such proceeding which remains undismissed for a period of sixty (60)
days, or any order approving the petition in any such proceeding is entered, or
Lessee by any act indicates its consent to, or acquiescence in, any such
proceeding or the appointment of any receiver or trustee for Lessee or any
substantial part of its property, or suffers any such receivership or
trusteeship to continue undischarged for a period of sixty (60) days, or any
party holding a security interest in any of Lessee's fixtures or personal
property of any nature whatsoever that are located on the Leased Premises
institutes or gives notice of foreclosure against any such property, then, in
any of such events, Lessor may immediately or at any time thereafter and without
demand or notice enter upon the Leased Premises or any part thereof in the name
of the whole and repossess the same as of Lessor's former estate and expel
Lessee and those claiming through or under Lessee and remove their effects
forcibly if necessary, without being deemed guilty of any manner of trespass and
without prejudice to any remedies which might otherwise be used for arrears of
rent or preceding breach of covenant, and upon such entry this Lease shall
terminate, and





                                       18
<PAGE>

Lessee covenants that, in case of such termination or in case of termination
under the provisions of statute by reason of the default of Lessee, Lessee shall
remain and continue liable to Lessor in an amount equal to the total rent
reserved for the balance of the term plus all additional rent reserved for the
balance of the term hereof less the net amounts (after deducting the expenses of
repair, renovation or demolition) which Lessor realizes, or with due diligence
should have realized from the reletting of the Leased Premises, plus all costs
associated with the correction of the default or the termination of the Lease,
including Lessor's reasonable attorney's fees. As used in this Section, the term
"additional rent" means the value of all considerations other than rent agreed
to be paid or performed by Lessee hereunder, including, without limiting the
generality of the foregoing, taxes, assessments, maintenance charges and
insurance premiums. Lessor shall have the right from time to time to relet the
Leased Premises upon such terms as they may deem fit, and if a sufficient sum
shall not be thus realized to yield the net rent required under this Lease,
Lessee agrees to satisfy and pay all deficiencies as they may become due during
each month of the remaining term of this Lease. Nothing herein contained shall
be deemed to require Lessor to await the date whereon this Lease, or the term
hereof, would have expired had there been no default by Lessee, or no such
termination or cancellation. Lessee expressly waives service of any notice of
intention to reenter and waives any and all right to recover or regain
possession of the Leased Premises, or to reinstate or redeem this Lease as may
be permitted or provided for by or under any statute or law now or hereafter in
force and effect. The rights and remedies given to Lessor in this Lease are
distinct, separate and cumulative remedies, and no one of them, whether or not
exercised by Lessor, shall be deemed to be in exclusion of any of the others
herein or by law or equity provided. Nothing contained in this Section shall
limit or prejudice the right of Lessor to prove and obtain, in proceedings
involving the bankruptcy or insolvency of, or a composition with creditors by,
Lessee the maximum allowed by any statute or rule of law at the time in effect.

                                   SECTION 24

                               ACCESS TO PREMISES

         Lessor or its representatives shall have free access to the Leased
Premises at reasonable intervals during normal business hours for the purpose of
inspection, or for the purpose of showing the Premises to prospective purchasers
or tenants, or for the purpose of making repairs which Lessee is obligated to
make hereunder but has failed or refused to make. The preceding sentence does
not impose upon Lessor any obligation to make repairs. During the One Hundred
Twenty (120) days next preceding the expiration of this Lease, Lessor may keep
affixed to any





                                       19
<PAGE>

suitable part of the outside of the building on the Leased Premises a notice
that the Leased Premises are for sale or rent.

                                     NOTICES

         Any written notice, request or demand required or permitted by this
Indenture shall, until either party shall notify the other in writing of a
different address, be properly given if hand delivered or sent by certified or
registered first class mail, postage prepaid, and addressed as follows:

         If to Lessor:  FIVE N ASSOCIATES

                        Nashua, NH 03060

                                   SECTION 26

                           SIGNS; EXTERIOR APPEARANCE

         Lessee may advertise its presence in the Leased Premises, provided,
however, that the signage shall conform to the ordinances of the City of Nashua
and shall be placed on the sign fronting the Everett Turnpike.
Lessor shall have the prior right to approve the signage to be placed by Lessee.

                                   SECTION 27

                                 OPTION TO RENEW

         Provided Lessee be not at the time in default in the payment of the
rent or in the performance of any of its obligations hereunder, the Lessee, upon
not less than one hundred twenty (120) days notice in writing to Lessor, may
renew this Lease for one (1) additional term of three (3) years. Such renewal
shall be upon all of the terms and conditions of this Lease except that there
shall be no further option of renewal following the last renewal term and the
rent for the renewal term shall be as set forth in Section 28 hereof.

                                   SECTION 28

                              RENT FOR RENEWAL TERM

         28.1     If the first option to renew shall be exercised, the base
monthly rent during such renewal term shall be an amount determined by
multiplying the monthly rent of Two Thousand Nine Hundred Eighty-Seven Dollars
and Twenty-Nine Cents ($2,987.29) by a fraction, the numerator of which shall be
the Price Index on the first of the month closest to the expiration of the
original term hereof, and the denominator of which shall be the Price Index as
of the month prior to the beginning of the term hereof; PROVIDED, HOWEVER, that
if such fraction is one or less the base monthly rent shall be Two Thousand Nine
Hundred Eighty-Seven Dollars and Twenty-Nine Cents ($2,987.29).

         28.2     As used in this paragraph, the term "Price Index" means (i)
the "Consumers' Price Index - For all urban consumers, U.S. City Average, All
Items, (1982-84 = 100) (referred to as CPI-U)" published by the Bureau of Labor
Statistics of the United States Department of Labor, or (ii) if the publication
of such Consumers' Price Index shall be discontinued, the comparable index most
closely reflecting diminution of the real value of the base rent herein provided
for. In the event of a change in the base rent for the Price Index, the
