                                    SUBLEASE

         This SUBLEASE, dated July 31, 2003, is made by and between Corning
Property Management Corporation ("Sublandlord"), a Delaware corporation, and
Avanex Corporation ("Subtenant"), a Delaware corporation.

         WHEREAS, the parties have entered into a Share Acquisition and Asset
Purchase Agreement dated May 12, 2003 (the "Purchase Agreement"), pursuant to
which Subtenant has agreed to purchase and Sublandlord shall has agreed to sell
Subtenant certain assets of Sublandlord's business located on the Demised
Premises (as defined below), as well as certain other assets; and

         WHEREAS, The Steuben County Industrial Development Agency ("SCIDA") as
tenant entered into a Lease Agreement dated December 1, 2001, as amended from
time to time with Corning Incorporated (as property owner or "Parent") and
thereafter entered into a Leaseback Agreement, as amended from time to time with
Parent dated December 1, 2001 ("Master Lease"); and

         WHEREAS, Parent assigned the Master Lease to Sublandlord by that
certain Assignment and Assumption Agreement between Parent and Sublandlord dated
as of December 1, 2001; and

         WHEREAS, the Subtenant desires to continue to conduct the businesses
conducted at the Demised Premises prior to the effective date of the Purchase
Agreement and Sublandlord desires to sublease the Demised Premises to Subtenant
for such purpose, pursuant to the terms of this Sublease.

         NOW, THEREFORE, the parties hereto, for themselves, their successors
and assigns, hereby covenant as follows:

ARTICLE I.THE DEMISED PREMISES AND SUBTENANT'S PERMITTED USE

         Section 1.01 Demised Premises.

         Sublandlord hereby subleases to Subtenant, and Subtenant hires from
Sublandlord, subject to the terms, conditions and provisions contained in this
Sublease, certain real property located at 9676 Lynn Morse Drive, Painted Post,
Steuben, County, New York, which real property is further described on EXHIBIT
A-1 attached hereto, together with all of Sublandlord's buildings (the
"Buildings") and improvements, located thereon, all as shown on EXHIBIT A-2
attached hereto (collectively, the "Demised Premises" or "Premises"). Equipment
identified on EXHIBIT A-3 shall be used by Subtenant during the Sublease Term
and shall remain the property of Sublandlord. Subtenant covenants that it shall
use such equipment for the purpose and manner it is intended, shall keep the
equipment in good condition and shall repair such equipment as necessary at its
own expense, costs related to reasonable wear and tear excluded. Information
Technology Assets that have been, or will be transferred to Subtenant, are
identified on EXHIBIT A-4.

         Section 1.02 Subtenant's Permitted Use.

         Subtenant may use and occupy the Demised Premises for the manufacturing
of electronic and/or optical products using processes comparable to the
manufacturing currently conducted on the Demised Premises and for associated
research and development, office, parking and other legal

<PAGE>

related uses and for no other use whatsoever. Subtenant's use and occupancy of
the Demised Premises shall in no way adversely affect the qualification of the
Demised Premises as a "project" as such quoted term is defined in Section 854 of
Article 18-A of the General Municipal Law of The State of New York (the "Act").

ARTICLE II. CONDITION OF DEMISED PREMISES

         Notwithstanding anything to the contrary in this Sublease, Sublandlord
warrants and represents that as of the Commencement Date (as defined in Article
III below), (i) the Demised Premises will be in good condition and repair and
the electrical, mechanical, HVAC, plumbing, elevator and other systems serving
the Demised Premises will be in good condition and repair; and (ii) the Demised
Premises shall conform to all requirements of covenants, conditions,
restrictions and encumbrances ("CC&R's"), all underwriter's requirements, and
all rules, regulations, statutes, ordinances, laws and building codes,
(collectively, "Laws") applicable thereto. Subtenant shall not be required to
construct or pay the cost of complying with any CC&R's, underwriter's
requirements or Laws requiring construction of improvements in the Premises
which are properly capitalized under general accounting principles, unless such
compliance is necessitated solely because of Subtenant's particular use of the
Demised Premises. Subtenant's acceptance of the Demised Premises shall not be
deemed a waiver of Subtenant's right to have defects in the Demised Premises
repaired at Sublandlord's sole expense. Subtenant shall give notice to
Sublandlord whenever any such defect becomes reasonably apparent, and
Sublandlord shall repair such defect as soon as practicable. Sublandlord also
hereby assigns to Subtenant all warranties with respect to the Premises, which
would reduce Subtenant's maintenance obligations hereunder and shall cooperate
with Subtenant to enforce all such warranties. Except as otherwise expressly
provided in this Sublease, Subtenant accepts possession of the Demised Premises
in its "as is" condition as of the date of this Sublease. SCIDA makes no
representations or warranties to the condition of or title to the Demised
Premises.

ARTICLE III. TERM

         The initial term of this Sublease ("Initial Term") shall commence as of
the date of this Sublease (the "Commencement Date") and shall continue until
July 31, 2005 at 11:59 p.m. So long as Subtenant is not then in Default as
defined in Section 15.01 hereof, Subtenant shall have two (2) two (2) year
options to renew this Sublease on the terms and conditions of EXHIBIT B attached
hereto. (Each such additional two-year period hereinafter referred to as a
"Renewal Term"). The Initial Term and all renewals thereof shall together be
referred to as the "Term". Subtenant hereby agrees that if it fails to surrender
the Premises at the end of the Term, or any renewal thereof, (i) all of the
terms of this Sublease shall continue on a month-to-month basis until terminated
by either party by not less than thirty (30) days prior written notice to the
other; (ii) Subtenant will be liable to Sublandlord for any and all damages
which Sublandlord shall suffer by reason thereof; and (iii) Subtenant will
indemnify Sublandlord against all claims and demands made by any succeeding
subtenants against Sublandlord, founded upon delay by Sublandlord in delivering
possession of the Premises to such succeeding subtenant.

ARTICLE IV. RENT AND SECURITY DEPOSIT

         Section 4.01 Base Rent.

                                       2

<PAGE>

During the Initial Term, Subtenant shall pay base rent (the "Base Rent") to
Sublandlord at the annual rate of $[*], which Base Rent shall be paid annually
on the Commencement Date and each anniversary thereof.

         Section 4.02 Additional Rent/Payment of Operating Expenses.

         Wherever it is provided in this Sublease that Subtenant is required to
make any payment other than Base Rent to Sublandlord, the payment shall be
deemed to be "Additional Rent" and all remedies applicable to the non-payment of
Base Rent shall also be applicable to the nonpayment of Additional Rent. As used
herein the word "Rent" shall mean, collectively, Base Rent and Additional Rent.
Subtenant agrees to pay, as Additional Rent, the following: (i) Subtenant's
portion of Major Capital Repairs as provided in Section 6.01 below, and (ii)
Sublandlord's out-of-pocket costs for third party contracts maintained by
Sublandlord (including, without limitation, those contained on EXHIBIT A-5
attached hereto) with respect to Sublandlord's repair and maintenance
obligations set forth in Section 6.03 hereof, (iii) Sublandlord's charges for
the Culinary Services pursuant to Section 7.03 hereof, and (iv) Sublandlord's
charges for the Security Services pursuant to Section 7.04 hereof (collectively,
the "Sublandlord Operating Expense Charges"). Sublandlord shall provide an
invoice to Subtenant for Sublandlord Operating Expense Charges no more
frequently than once per calendar month. Subtenant shall reimburse Sublandlord
for the invoiced amount of Sublandlord's Operating Expense Charge no later than
thirty (30) days following Subtenant's receipt thereof. Upon request,
Sublandlord shall promptly provide Subtenant with back-up information regarding
the Sublandlord Operating Expense Charges. The parties shall cooperate in good
faith to resolve any disputes regarding invoiced amounts.

         Section 4.03 Taxes.

         A.       As used in this Sublease, the term "Real Property Taxes" shall
mean all taxes, assessments, water, sewer, or other rents and charges, excises,
levies, fees (including, without limitation, licenses, permits, inspections,
authorizations and similar fees), and all other governmental charges, whether
general or special, ordinary or extraordinary, foreseen or unforeseen, which are
imposed against all or any portion of the Demised Premises during the Term. If,
at any time during the Term, the methods of taxation prevailing on the
Commencement Date shall be altered, modified, or changed, in whole or in part,
so that in lieu of, or as an addition to, or as a substitute for the whole or
any part of the Real Property Taxes, there shall be levied, assessed or imposed
on the Demised Premises any new taxes, assessments, levies, impositions, charges
or special assessments, then all such taxes, assessments, levies, impositions,
charges or special assessments shall be deemed to be included within the term
Real Property Taxes.

         B.       Subtenant shall pay, on the first day of each month 1/12th of
the annual Real Property Taxes paid by Sublandlord for the fiscal tax year the
applicable month occurs.

         C.       If, at any time during the Term, a tax on Rent or other tax,
however described, is assessed, levied or imposed upon the Demised Premises or
against Sublandlord under the laws of the State of New York or any political
subdivision thereof, in lieu of, or as a substitute in whole or in part for, the
Real Property Taxes referred to in Section 4.03.A, then the same shall be deemed
included in the term "Real Property Taxes.

<PAGE>

         D.       Real Property Taxes which accrue partially prior to the
Commencement Date and subsequent to the expiration or termination of this
Sublease shall be equitably apportioned so that Subtenant shall pay only such
portion of such Real Property Taxes as shall be attributable to the portion of
any such fiscal tax year occurring during the Term.

         E.       Notwithstanding anything to the contrary in this Sublease, the
definition of "Real Property Taxes" shall not include taxes, assessments, or
governmental levies on Sublandlord's income, or with respect to any inheritance
or estate planning or with respect to any improvements or services not made
available for Subtenant's use or that do not otherwise benefit Subtenant. In no
event shall Subtenant be responsible or liable in any manner for any payment,
clawback, charge, expense, reimbursement or liability associated with any tax
abatements or tax benefits granted to Sublandlord or any Affiliate of
Sublandlord (as defined in the Purchase Agreement).

         F.       Not withstanding anything to the contrary in the Sublease or
any other document, Subtenant's agreement to pay Real Property Taxes shall in no
way relieve, discharge or reduce Sublandlord's obligation to make payments under
that Certain Payment-in-Lieu-of-Tax-Agreement, dated as of December 1, 2001, by
and between Sublandlord (as assignee of Parent) and SCIDA, as amended from time
to time (the "PILOT Agreement").

         Section 4.04 Sublandlord's Casualty Insurance.

                  Subtenant shall pay, on a monthly basis at the same time as
monthly payments of Base Rent are due, 1/12th of the annual insurance premium
paid by Sublandlord for the casualty insurance policy referenced in Section
11.03(a).

         Section 4.05 Place of Payment.

                  Rent shall be payable by Subtenant to Sublandlord to the
attention of President, Corning Property Management Corporation, at the address
set forth in Section 19.04(C) hereof or at any other place designated by notice
given by Sublandlord to Subtenant pursuant to Section 19.04.

         Section 4.06 Late Fee.

                  Any Rent payment that is not made when due shall be subject to
a late fee equal to five percent (5%) of the amount not paid when due for each
month or portion thereof from the due date to the date of payment.

         Section 4.07 Security Deposit.

                  No later than five (5) business days after execution of the
Lease, Subtenant will provide a security deposit in the amount of $[*] in
readily available funds payable to Sublandlord (the "Deposit"). The Deposit
provided herein shall be considered as security for the payment and performance
by Subtenant of all Subtenant's obligations covenants, conditions and agreements
under this Lease. In the event of any default by Subtenant hereunder,
Sublandlord shall have the right, but shall not be obligated, to apply all or
any portion of the Deposit to cure such default, in which event Subtenant shall
be obligated to promptly Deposit with Sublandlord that portion of the Deposit
used to cure the default. In the event Subtenant fails to perform its
obligations, said Deposit shall not be

<PAGE>

deemed liquidated damages, and application of the Deposit to reduce Subtenant's
damages shall not preclude Sublandlord from recovering additional damages
incurred by Sublandlord. The Deposit (or any remaining portion after proceeds
have been applied by Sublandlord to a default of Subtenant hereunder as
permitted herein) shall be returned by Sublandlord to Subtenant within thirty
(30) days of the Lease termination. If Sublandlord assigns or transfers its
interest in the Premises, Sublandlord shall deliver or credit the Security
Deposit to Sublandlord's successor in interest in the Premises and thereupon be
relieved of further responsibility with respect to the Security Deposit so long
as such assignee or transferee expressly agrees in writing to return such
Security Deposit to Subtenant in accordance with this Section 4.07.

ARTICLE V. ALTERATIONS, SIGNS

         Section 5.01 Alterations to the Demised Premises.

         Upon prior notice to Sublandlord, Subtenant shall have the right to
perform any nonstructural alterations, installations, additions, improvements or
capital replacements to the Demised Premises (collectively "Alterations")
costing less than $[*] per project. Subtenant shall not perform any structural
Alterations or any Alterations costing more than $[*] per project without
obtaining the prior written consent of Sublandlord, which consent shall not be
unreasonably withheld, conditioned or delayed. Any Alterations shall be
performed at Subtenant's sole expense, in a good and workmanlike manner and in
compliance with all laws applicable to the Demised Premises. Upon substantial
completion of any Alterations, Subtenant shall provide Sublandlord with a copy
of any as-built plans of the Alterations that it has obtained at Subtenant's
sole costs and expense. Any approval of Sublandlord shall not be construed as an
opinion as to whether the Alterations will comply with applicable laws or be
sufficient for Subtenant's purposes and Sublandlord shall have no liability
therefore. Notwithstanding anything to the contrary contained in this Section
5.01, Sublandlord acknowledges that Subtenant shall not be required to provide
Sublandlord notice or obtain Sublandlord's consent in the event Subtenant is
relocating its personal property, including its equipment or machinery
("Subtenant's Equipment Relocation") notwithstanding the amount of the cost of
Subtenant's Equipment Relocation. Any such alterations or Subtenant's Equipment
Relocation shall not result in the use and operation of the Demised Premises to

         It is the intent that the service contracts listed on EXHIBIT A-6
attached hereto be assigned to Subtenant as of the Commencement Date or that

Sublandlord shall have the right to charge Subtenant the out-of-pocket costs of
the Sublandlord Service Contracts pursuant to Section 4.02 hereof. Sublandlord
shall have the right to change vendors or re-negotiate the Sublandlord Service
Contracts, provided, however, that if the change of any vendor or contract
results in a material increase in the cost of the service covered by such
contract, Sublandlord shall consult with Subtenant with respect to such
contract, and Subtenant shall have the right, on thirty (30) days advance
written notice to Sublandlord, to assume in writing the repair and maintenance
responsibilities relating to such contract under Section 6.01, and upon such
assumption, Sublandlord shall no longer have the corresponding responsibility

caused by circumstances beyond the control of Subtenant that continues for a
period of sixty (60) days or more and is not caused by damage or casualty to the
Premises (which time period shall not commence until Subtenant has provided

to the Security Services shall be provided at a reasonable cost that is agreed
upon by the Parties. Sublandlord will provide the Security Services to Subtenant
for the Term of this Lease Agreement, provided, however, Subtenant may terminate

ARTICLE XII. CONDEMNATION

         A.       If all the Demised Premises are taken by eminent domain (a
"Taking"), this Sublease shall terminate when Subtenant is required to vacate
the Demised Premises.

         B.       If a partial Taking results in so much of the Demised Premises
being taken as to render the remaining portion of the Demised Premises
unsuitable for Subtenant's continued use and occupancy as reasonably determined
by Subtenant (hereinafter for the purposes of this Article XII "Material Partial
Taking"), then Subtenant may, by delivering written notice to Sublandlord within
sixty (60) days after Subtenant receives written notice of the Material Partial
Taking, elect to terminate this Sublease as of the date Subtenant is required to
vacate the portion of the Demised Premises so taken.

         C.       If a partial Taking does not result in a Material Partial
Taking, then this Sublease shall not be terminated and Sublandlord shall, to the
extent of any Taking proceeds actually received by Sublandlord, and to the
extent reasonably practical, proceed with all reasonable dispatch to do such
work that may be reasonably required to restore what remains of the Demised
Premises as nearly as may be to its condition prior to the Taking.

         D.       Sublandlord shall be entitled to any and all proceeds
resulting from any Taking with respect to Sublandlord's interest in the Demised
Premises.

survive the expiration or other termination of this Sublease.

         Notwithstanding anything to the contrary in this Section 13.02, except
to the extent of the gross negligence or willful misconduct of Sublandlord, or
any breach by Sublandlord of its obligations under this Sublease, Sublandlord
shall not be responsible or liable to Subtenant, or to those claiming by,
through or under Subtenant, for any loss or damage which may be occasioned by or
through the acts or omissions of persons occupying space adjoining the Premises
or any part of the premises adjacent to or connecting with the premises, or
otherwise, or for any loss or damage resulting to Subtenant, or those claiming
by, through or under Subtenant, or its property, from the breaking, bursting,

shall expire, Subtenant shall deliver to Sublandlord certificates for all
insurance which Subtenant is required to carry under the terms of this Sublease.
The renewal or replacement policy or certificate shall be delivered by Subtenant
to Sublandlord by certified mail, return receipt requested. If Subtenant fails
to give Sublandlord a copy of any required certificate of insurance within ten
(10) business days after written notice and demand therefore is given by
Sublandlord to Subtenant, in addition to the remedies provided in Article XV
below, Sublandlord may obtain and pay for that insurance coverage, in which
event the cost of such insurance coverage, together with interest at the
Interest Rate shall be due and payable by Subtenant as Additional Rent
immediately upon demand.

         B.       All insurance policies required to be carried under this
Sublease by or on behalf of either party (i) shall be issued by insurance
companies licensed to do business in the State of New

                                       16

<PAGE>

York, and maintaining during the policy term a "General Policyholders Rating" of
at least A-, as set forth in the most current issue of "Best's Insurance Guide"
and (ii) shall provide that (and any certificate evidencing the existence of any
insurance policies, shall certify that) unless Sublandlord shall have been given
thirty (30) days' written notice of any cancellation, the insurance shall not be
canceled and shall continue in full force and effect.

ARTICLE XIV. COVENANT OF QUIET ENJOYMENT

         Sublandlord covenants that provided a "Default" (as defined in Article
XV below) has not occurred under this Sublease, Subtenant shall at all times
during the Sublease Term peaceably and quietly have, hold and enjoy the Demised
Premises, without any interruption or disturbance.

ARTICLE XV. DEFAULTS & REMEDIES

         Section 15.01 Defaults.

         Any of the following shall constitute a "Default" under this Sublease:

         A.       Subtenant shall fail to pay any installment of Rent when the
same shall be due and payable, and such failure shall continue for a period of
ten (10) days after receipt by Subtenant of written notice thereof from
Sublandlord; or

         B.       If Subtenant shall fail to maintain the insurance coverage
required by this Sublease or Subtenant shall fail to timely deliver a copy of
any certificate of insurance required hereunder and such default shall continue
for a period of ten business (10) days after written notice is given by
Sublandlord to Subtenant specifying such default; or default shall be made with
respect to any assignment of this Sublease or subletting of the Demised Premises
as provided in Article IX hereof; or default shall be made with respect to
Subtenant's obligation to make certifications as provided in Article XVI
hereof(such notice provided herein constituting a second notice in addition to
that provided for in Article XVI); or

         C.       Subtenant shall fail to perform any of the other covenants,
conditions and agreements herein contained on Subtenant's part to be performed
and such failure shall continue for a period of thirty (30) days after receipt
by Subtenant of notice in writing from Sublandlord specifying in detail the
nature of such failure, except that if within the thirty (30) day period
Subtenant commences and thereafter proceeds diligently to remedy the violation
or failure within a reasonable period of time, Subtenant shall not be in default
hereunder.

         D.       Subtenant shall file a voluntary petition in bankruptcy or
shall be adjudicated a bankrupt or insolvent or shall file any petition or
answer seeking any reorganization, arrangement, composition, readjustment,
liquidation, dissolution or similar relief under the present or any future
federal bankruptcy act or any other present or future applicable federal, state
or other stature or law, or shall seek or consent to or acquiesce in the
appointment of any trustee, receiver or liquidator of Subtenant or of all or any
substantial part of its properties or of the Demised Premises; or

         E.       If within sixty (60) days after the commencement of any
proceeding against Subtenant seeking any reorganization, arrangement
composition, readjustment, liquidation, dissolution or similar relief under the
present or any future federal bankruptcy act or any other present or future
applicable

                                       17

<PAGE>

federal, state or other statute or law, such proceeding shall not have been
dismissed, or if, within sixty (60) days after the appointment, without the
consent or acquiescence of Subtenant of any trustee, receiver or liquidator of
Subtenant, or of all or any substantial part of its properties or of the Demised
Premises, such appointment shall not have been vacated or stayed on appeal or
otherwise, or if, within sixty (60) days after the expiration of any such stay,
such appointment shall not have been vacated.

         F.       The abandonment of the Demised Premises by Subtenant at any
time following delivery of possession of the Demised Premises to Subtenant.

         Section 15.02 Sublandlord Remedies.

         A.       After the occurrence of a Default, Sublandlord may, at its
option, give Subtenant a notice of election to end the Term upon a date
specified in such notice, which date shall not be less than five (5) days after
the date such notice is given to Subtenant, and upon the date specified in such
notice, this Sublease and the Term shall cease and any and all other right,
title and interest of Subtenant hereunder shall likewise cease without further
notice or lapse of time, as fully and with like effect as if the entire Term had
elapsed, but Subtenant shall continue to be liable to Sublandlord as hereinafter
provided.

         B.       Upon any termination of this Sublease pursuant to Section
15.02(A) or at any time thereafter, Sublandlord may, in addition to and without
prejudice to any other rights and remedies Sublandlord shall have at law or in
equity, re-enter the Demised Premises and recover possession thereof and
dispossess any or all occupants of the Demised Premises in the manner prescribed
by the statute relating to summary proceedings, or similar statutes; but
Subtenant in such case shall remain liable to Sublandlord as hereinafter
provided.

         C.       Upon any termination of this Sublease pursuant to Section
15.02(A), (i) the Rent shall become due thereupon and be paid up to the time of
such reentry, expiration and/or dispossession; and (ii) Subtenant or the legal
representatives of Subtenant shall also pay Sublandlord as damages for the
failure of Subtenant to observe and perform Subtenant's covenants herein
contained, any deficiency between the Rent hereby reserved and/or covenanted to
be paid and the net amount, if any, of the rents collected on account of any
sublease or subleases of the Demised Premises entered into by Sublandlord for
each month of the period which would otherwise have constituted the balance of
the Term. When determining the balance of the Term for the purposes of this
Section 15.02(c), it will be assumed that Subtenant would, on the date the
Sublease is terminated by Sublandlord, have exercised its election to terminate
or not renew the Sublease pursuant to Article III. Any such damages shall be
paid in monthly installments by Subtenant on the first day of each month, and
any suit brought to collect the amount of the deficiency for any month shall not
prejudice in any way the fight of Sublandlord to collect the deficiency for any
subsequent month by a similar proceeding.

         D.       In the event of the occurrence of a Default, or a threatened
breach by Subtenant of any of the agreements, terms, covenants or conditions of
this Sublease on Subtenant's part to be performed, Sublandlord shall have the
right to enjoin such Default or threatened breach by Subtenant.

         E.       If Subtenant shall fail to perform or observe any term or
condition in this Sublease, and shall not cure such failure within ten (10)
business days after Sublandlord notifies Subtenant of such failure or shall have
not commenced a cure during such time period and be diligently prosecuting such
cure to completion, Sublandlord may, but shall not be obligated to, cure such
failure by Subtenant under this Sublease. Whenever Sublandlord so elects to
cure, all costs and expenses incurred by

                                       18

<PAGE>

Sublandlord, including reasonable attorneys' fees, shall be considered Rent
hereunder and shall be paid by Subtenant to Sublandlord within five (5) days of
demand, together with interest at the Interest Rate.

         F.       No acceptance by Sublandlord of a lesser sum than the Rent, or
any charge then due shall be deemed to be other than on account of the earliest
installment of such Rent or charge due, nor shall any endorsement or statement
on any check or any letter accompanying any check or payment as Rent or other
charge be deemed as an accord and satisfaction, and Sublandlord may accept such
check or payment without prejudice to Sublandlord's right to recover the balance
of such installment or pursue any other remedy in this Sublease provided.

         G.       Any failure of Sublandlord to complain of any act or omission
on the part of Subtenant, no matter how long the same may continue, shall not be
deemed to be a waiver by Sublandlord of any of its rights hereunder. No waiver
by Sublandlord at any time, express or implied, of any breach of any provision
of this Sublease shall be deemed a waiver of a breach of any other provision of
this Sublease or a consent to any subsequent breach of the same or any other
provision. No covenant term or condition of this Sublease shall be deemed to
have been waived by Sublandlord, unless such waiver is acknowledged in writing
by Sublandlord.

         H.       Each right and remedy provided for in this Sublease shall be
cumulative and shall be in addition to every other right or remedy provided for
in this Sublease or now or hereafter existing at law or in equity or by statute
or otherwise, and the exercise or beginning of the exercise by Sublandlord of
any one or more of the rights or remedies provided for in this Sublease, or now
or hereafter existing in law or in equity, shall not preclude the simultaneous
or later exercise by Sublandlord of any or all other available rights or
remedies Sublandlord may elect. In no event shall either party be liable to the
other for consequential or incidental damages. In the event of any default of
Subtenant hereunder, Sublandlord shall act reasonably to mitigate its damages.

         I.       In the event Subtenant shall default more than two times by
failing to pay Rent when due, the five percent (5%) late fee referenced in
Section 4.06 shall be increased to ten percent (10%) to compensate Sublandlord
for additional administrative costs related to multiple breaches of this
Sublease by Subtenant.

         J.       If a judicial remedy is necessary to enforce or interpret any
provision of the Sublease, the prevailing party shall be entitled to reasonable
attorneys' fees, costs and other expenses, in addition to any other relief to
which is available under the terms of this Sublease.

         Section 15.03 Sublandlord Default.

         In the event Sublandlord fails to perform any of its obligations under
this Sublease and (except in case of emergency posing an immediate threat to
persons or property, in which case no prior notice shall be required) fails to
cure such default within thirty (30) days after written notice from Subtenant
specifying the nature of such default where such default could reasonably be
cured within said thirty (30) day period, or fails to commence such cure within
said thirty (30) day period and thereafter continuously with due diligence
prosecute such cure to completion where such default could not reasonably be
cured within said thirty (30) day period, then Subtenant may: (i) proceed in
equity or at law to compel Sublandlord to perform its obligations and/or to
recover damages proximately caused by such failure to perform (except to the
extent Subtenant has waived its right to damages resulting from injury to person
or damage to property as provided herein); or (ii) cure any

                                       19

<PAGE>

default of Sublandlord at Sublandlord's cost. If Subtenant at any time by reason
of Sublandlord's default reasonably pays any sum or does any act that requires
the payment of any sum, the sum paid by Subtenant shall be immediately due from
Sublandlord to Subtenant at the time the sum is paid. Any and all rights and
remedies herein created for Subtenant shall be cumulative and use of one remedy
shall not be taken to exclude or waive the right to the use of another and
Subtenant shall have the remedies available to Subtenant under applicable law.

ARTICLE XVI. ESTOPPEL CERTIFICATE

         At any time within ten business (10) days after request by Sublandlord
or Subtenant ("Requesting Party"), by written instrument, duly executed and

the date to which such rental has been paid; and

         E.       Such other terms, covenants and conditions which the

certificate shall reasonably require.

         A.       Upon one (1) day advance oral notice, inspect the Demised

equipment. Sublandlord shall use its best efforts to minimize disruption to
Subtenant's operations during such access.

         Section 17.02 Sublandlord's Covenants.

         If Sublandlord enters the Demised Premises, Sublandlord shall do so

Sublandlord shall comply with all reasonable security and health and safety
requirements of Subtenant.
