Attn:  John R. Alm, Chief Executive Officer

     Re:  1998-2010 Cold Drink Equipment Purchase Partnership
          Program ("Program")

Dear John:

This letter agreement ("Amendment") amends the letter agreement ("Canadian CAPPr
Agreement") dated January 23, 2002 among Coca-Cola Ltd. ("CCL") and Coca-Cola
Bottling Company ("CCBC"). All capitalized terms used in this Amendment have the
same meaning given to them in the Canadian CAPPr Agreement unless otherwise
defined herein.

Effective January 1, 2004 the parties agree to amend the Canadian CAPPr
Agreement as follows:

Term
----

The "Term" paragraph of the Canadian CAPPr Agreement, which currently reads,

          "Except as otherwise provided herein, the term of this agreement is
          eleven (11) years, beginning as of January 1, 1998, and ending
          December 31, 2008 ("Term"). If CCBC is required to perform any
          obligations of the Program after the end of the eleven-year Term, such
          obligations of CCBC shall remain in effect beyond the eleven-year
          Term."

<PAGE>

is hereby deleted in its entirety and replaced with the following:

          "Except as otherwise provided herein, the term of this Agreement is
          thirteen (13) years, beginning as of January 1, 1998 and ending
          December 31, 2010 ("Term"). If CCBC is required to perform any
          obligations of the Program after the end of the thirteen-year Term,
          such obligations of CCBC shall remain in effect beyond the
          thirteen-year Term."

Purchase Plan
-------------

The second paragraph in the "Purchase Plan" section of the Canadian CAPPr
Agreement, which currently reads,

          "As part of the Plan CCBC agrees to purchase and place, at a minimum,
          242,665 cumulative units of cold drink equipment in the Division over
          the eleven (11) year period from and including 1998 to 2008 (as
          provided in Exhibit B).

is hereby deleted in its entirety and replaced with the following:

          "As part of the Plan CCBC agrees to purchase and place, at a minimum,
          242,665 cumulative units of cold drink equipment in the Division over
          the thirteen (13) year period from and including 1998 to 2010 (as
          provided in Exhibit B).

In addition, Exhibit B attached to the Canadian CAPPr Agreement is deleted in
its entirety and replaced with the following:

*** Material hs been omitted pursuant to a request for confidential treatment
and filed separately with the SEC.

In view of the fact that fewer units of cold drink equipment will be purchased
and placed in the Division in 2004 and 2005 than originally planned, and for the
fact that half of the purchases and placements originally planned for 2004 and
2005 will now occur in 2009 and 2010, CCBC agrees to pay CCL a total of
$2,000,000US as follows: $200,000US annually in years 2004 and 2009, and
$400,000US annually in years 2005 through and including 2008.

This Amendment shall be executed simultaneously with the August 9, 2004
amendment to the Cold Drink Equipment Purchase Partnership Program dated January
23, 2002 between The Coca-Cola Company and Coca-Cola Enterprises Inc.

CCL and CCBC agree that this Amendment may be executed in counterparts and if so
executed in counterparts, will be enforceable and effective upon the exchange of
executed counterparts or the exchange of facsimile transmissions of the executed
counterparts.

Except as stated herein, all other terms of the Canadian CAPPr Agreement remain
unchanged.

CCL and CCBC each expressly acknowledge that this letter agreement was
negotiated at arms length, is valid and enforceable according to its terms, and
is supported by adequate consideration.

If this accurately reflects our agreement and understanding, please sign where
indicated below and return a signed copy to me.

Sincerely,

COCA-COLA LTD.

         1. GRANTING CLAUSE. In consideration of the obligation of Tenant to pay
rent as herein provided and in consideration of the other terms, covenants, and
conditions hereof, Landlord leases to Tenant, and Tenant takes from Landlord,
the Premises, subject to the terms, covenants and conditions of this Lease.

                                      -2-
<PAGE>

         2. ACCEPTANCE OF PREMISES. Tenant shall accept the Premises in its
condition as of the Commencement Date, subject to all applicable laws,
ordinances, regulations, covenants and restrictions. Landlord has made no
representation or warranty as to the suitability of the Premises for the conduct
of Tenant's business, and Tenant waives any implied warranty that the Premises
are suitable for Tenant's intended purposes. Except as provided in Paragraph 10,
in no event shall Landlord have any obligation for any defects in the Premises
or any limitation on its use. The taking of possession of the Premises shall be
conclusive evidence that Tenant accepts the Premises and that the Premises were
in good condition at the time possession was taken except for items that are
Landlord's responsibility under Paragraph 10 and any punchlist items agreed to
in writing by Landlord and Tenant. Landlord represents and warrants, to its
knowledge, that as of the Commencement Date, Landlord has full power, right and
authority to execute and perform this Lease and all corporate action necessary
to do so has been duly taken and that the Premises are zoned Light Industrial.
See Addendum #2.

         3. USE. The Premises shall be used only for the purposes of receiving,
storing, shipping and selling (but limited to wholesale sales) products,
materials and merchandise made and/or distributed by Tenant, for manufacturing
and assembly, and for such other lawful purposes as may be incidental thereto.
Tenant will use the Premises in a careful, safe and proper manner and will not
commit waste, overload the floor or structure of the Premises or subject the
Premises to use that would damage the Premises. Tenant shall not permit any
objectionable or unpleasant odors, smoke, dust, gas, noise or vibrations to
emanate from the Premises, or take any other action that would constitute a
nuisance or would disturb, unreasonably interfere with, or endanger Landlord or
any other tenants of the Project. Outside storage, including without limitation,
storage of trucks and other vehicles, is prohibited without Landlord's prior
written consent. Tenant, at its sole expense, shall use and occupy the Premises
in compliance with all laws, orders, judgments, ordinances, regulations, codes,
directives, permits, licenses, covenants and restrictions now or hereafter
applicable to the Premises (collectively, "Legal Requirements"). Tenant shall,
at its expense, make any alterations or modifications, within or without the
Premises, that are required by Legal Requirements related to Tenant's use or
occupation of the Premises. Any occupation of the Premises by Tenant prior to
the Commencement Date shall be subject to all obligations of Tenant under this
Lease.

         4. BASE RENT. Tenant shall pay Base Rent in the amount set forth above,
plus the corresponding value added tax that may be due pursuant to Mexican or
other applicable law. The first month's Base Rent, the Security Deposit, and the
first monthly installment of estimated Operating Expenses (as hereafter defined)
shall be due and payable on the date hereof, and Tenant promises to pay to
Landlord in advance, without demand, deduction or set-off, (unless as otherwise
required to be deducted by order or directive of applicable Legal Requirements),
monthly installments of Base Rent and estimated Operating Expenses on the first
day of each calendar month succeeding the Commencement Date. Payments of Base
Rent and estimated Operating Expenses for any fractional calendar month shall be
prorated. All payments required to be made by Tenant to Landlord hereunder shall
be payable by check or bank wire transfer at such address as Landlord and Tenant
mutually may specify from time to time by written notice delivered in accordance
herewith. The obligation of Tenant to pay Base Rent and other sums to Landlord
and the obligations of Landlord under this Lease are independent obligations.
Tenant shall have no right at any time to abate, reduce, or set-off any rent due
hereunder except as may be expressly provided in this Lease. If Tenant is
delinquent in any monthly installment of Base Rent or of estimated Operating
Expenses for more than 5 days, Tenant shall pay to Landlord on demand a late
charge equal to 5 percent of such delinquent sum. The provisions for such late
charge shall be in addition to all of Landlord's other rights and remedies
hereunder or at law and shall not be construed as a penalty. All payments
required to be made by Tenant to Landlord hereunder shall carry the
corresponding value added tax, as applicable, which shall be Tenant's
obligation.

                  The Base Rent and any other amounts payable by Tenant to
Landlord hereunder may be paid in Dollars, currency of the United States of
America or its equivalent in Mexican currency, on the date payment is received
by Landlord, at the exchange rate to meet obligations denominated in foreign
currency payable in the Mexican Republic, published by the Banco de Mexico in
the Official Gazette of the Federation on the date of payment. Should the
amounts received by Landlord in Mexican currency be less than the required
United States of America equivalency on the date of receipt, Tenant will, upon
demand, pay the difference to Landlord. See Addendum #1.

         5. SECURITY DEPOSIT. The Security Deposit shall be held by Landlord,
without interest, as security for the performance of Tenant's obligations under
this Lease. The Security Deposit is not an advance rental deposit or a measure
of Landlord's damages in case of Tenant's default. Upon each occurrence of an
Event of Default (as hereinafter defined), Landlord may use all or part of the
Security Deposit to pay delinquent payments due under this Lease, and the cost
of any damage, injury, expense or liability caused by such Event of Default,
without prejudice to any other remedy provided herein or provided by law. Tenant
shall pay Landlord on demand the amount that will restore the Security Deposit
to its original amount. Landlord's obligation respecting the Security Deposit is
that of a debtor, not a trustee; no interest shall accrue thereon. The Security
Deposit shall be returned to Tenant when Tenant's obligations under this Lease
have been completely fulfilled. Landlord shall be released from any obligation
with respect to the Security Deposit upon transfer of this Lease and the
Premises to a person or entity assuming Landlord's obligations under this
Paragraph 5, provided that the Security Deposit has been transferred to such
person or entity.

                                      -3-
<PAGE>

         6. OPERATING EXPENSE PAYMENTS. During each month of the Lease Term, on
the same date that Base Rent is due, Tenant shall pay Landlord an amount equal
to 1/12 of the annual cost, as estimated by Landlord from time to time, of
Tenant's Proportionate Share (as hereinafter defined) of Operating Expenses for
the Project, plus the corresponding value added tax that may be due pursuant to
Mexican or other applicable law. Payments thereof for any fractional calendar
month shall be prorated. The term "Operating Expenses" means all costs and
expenses incurred by Landlord with respect to the ownership, maintenance, and
operation of the Project including, but not limited to costs of: Taxes (as
hereinafter defined) and fees payable to tax consultants and attorneys for
consultation and contesting taxes; insurance; utilities; maintenance, repair and
replacement of all portions of the Project, including without limitation, paving
and parking areas, roads, roofs (including the roof membrane), alleys, and
driveways, mowing, landscaping, snow removal, exterior painting, utility lines,
heating, ventilation and air conditioning systems, lighting, electrical systems
and other mechanical and building systems; amounts paid to contractors and
subcontractors for work or services performed in connection with any of the
foregoing; charges or assessments of any association to which the Project is
subject; market-rate property management fees payable to a property manager,
including any affiliate of Landlord; security services, if any; trash
collection, sweeping and removal; and additions or alterations made by Landlord
to the Project or the Building in order to comply with Legal Requirements (other
than those expressly required herein to be made by Tenant) or that are
appropriate to the continued operation of the Project or the Building, provided
that the cost of additions or alterations that are required to be capitalized
for income tax purposes shall be amortized on a straight line basis over a
period equal to the lesser of the useful life thereof for income tax purposes or
10 years. Operating Expenses do not include costs, expenses, depreciation or
amortization for capital repairs and capital replacements required to be made by
Landlord under Paragraph 10 of this Lease, debt service under mortgages or
ground rent under ground leases, costs of restoration to the extent of net
insurance proceeds received by Landlord with respect thereto, leasing
commissions, or the costs of renovating space for tenants.

                  Tenant shall not be obligated to pay for Controllable
Operating Expenses in any year to the extent they have increased by more than
fifty percent (50%) per annum. For purposes of this Paragraph, Controllable
Operating Expenses shall mean all Operating Expenses as set forth in Paragraph 6
of the Lease, except for Taxes, insurance premiums and utility costs.
Controllable Operating Expenses shall be determined on an aggregate basis and
not on an individual basis, and the cap on Controllable Operating Expenses shall
be determined on Operating Expenses as they have been adjusted for vacancy or
usage pursuant to the terms of the Lease.

                  If Tenant's total payments of Operating Expenses for any year
are less than Tenant's Proportionate Share of actual Operating Expenses for such
year, then Tenant shall pay the difference to Landlord within 30 days after
demand, and if more, then Landlord shall retain such excess and credit it
against Tenant's next payments. For purposes of calculating Tenant's
Proportionate Share of Operating Expenses, a year shall mean a calendar year
except the first year, which shall begin on the Commencement Date, and the last
year, which shall end on the expiration of this Lease. With respect to Operating
Expenses which Landlord allocates to the entire Project, Tenant's "Proportionate
Share" shall be the percentage set forth on the first page of this Lease as
Tenant's Proportionate Share of the Project as reasonably adjusted by Landlord
in the future for changes in the physical size of the Premises or the Project;
and, with respect to Operating Expenses which Landlord allocates only to the
Building, Tenant's "Proportionate Share" shall be the percentage set forth on
the first page of this Lease as Tenant's Proportionate Share of the Building as
reasonably adjusted by Landlord in the future for changes in the physical size
of the Premises or the Building. Landlord may equitably increase Tenant's
Proportionate Share for any item of expense or cost reimbursable by Tenant that
relates to a repair, replacement, or service that benefits only the Premises or
only a portion of the Project or Building that includes the Premises or that
varies with occupancy or use. The estimated Operating Expenses for the Premises
set forth on the first page of this Lease are only estimates, and Landlord makes
no guaranty or warranty that such estimates will be accurate.

         7. UTILITIES. Tenant shall pay for all water, gas, electricity, heat,
light, power, telephone, sewer, sprinkler services, refuse and trash collection,
and other utilities and services used on the Premises, all maintenance charges
for utilities, and any storm sewer charges or other similar charges for
utilities imposed by any governmental entity or utility provider together with
any Taxes, penalties, surcharges or the like pertaining to Tenant's use of the
Premises. Landlord may cause at Tenant's expense any utilities to be separately
metered or charged directly to Tenant by the provider. Tenant shall pay its
share of all charges for jointly metered utilities based upon consumption, as
reasonably determined by Landlord. No interruption or failure of utilities shall
result in the termination of this Lease or the abatement of rent.

         8. TAXES. Landlord shall pay all real estate taxes, assessments and
governmental charges (collectively referred to as "Taxes") that specifically
accrue against the Project during the Lease Term, which shall be included as
part of the Operating Expenses charged to Tenant. Landlord may contest by
appropriate legal proceedings the amount, validity, or application of any real
estate Taxes or liens thereof. If Landlord fails to contest the real estate
taxes, Tenant shall have the right to request Landlord to contest such taxes,
and Landlord shall so contest, at Tenant's sole cost and expense (including,
without limitation, Landlord's reasonable attorneys' fees and reasonable fees
payable to tax consultants and attorneys for consultation and contesting taxes),
if, in Landlord's reasonable judgment, such contest is warranted; provided,
however, Tenant's request of such contesting of Taxes shall be limited to one
request in a calendar year. Landlord shall cooperate in the institution and
prosecution of any such proceedings of contesting taxes and will execute any
documents reasonably required therefor. All reductions, refunds, or rebates of
Taxes paid or payable by Tenant shall belong to Tenant whether as a consequence
of a Tenant proceeding or otherwise. All capital levies or other taxes assessed
or imposed on Landlord upon the rents payable to Landlord under this Lease and
any value added, franchise tax, any excise, transaction, sales or privilege tax,
assessment, levy or charge measured by or based, in whole or in part, upon such
rents from the Premises and/or the Project or any portion thereof shall be paid
by Tenant to Landlord monthly in full or in estimated installments or upon
demand, at the option of Landlord, as additional rent; provided, however, in no
event shall Tenant be liable for any net income taxes imposed on Landlord unless
such net income taxes are in substitution for any real estate Taxes payable
hereunder. If any such Taxes are levied or assessed directly against Tenant,
then Tenant shall be responsible for and shall pay the same at such times and in
such manner as the taxing authority shall require. Tenant shall be liable for
all taxes levied or assessed against any personal property or fixtures placed in
the Premises, whether levied or assessed against Landlord or Tenant.

         9. INSURANCE. Landlord shall maintain all risk property insurance
covering the full replacement cost of the Building. Landlord may, but is not
obligated to, maintain such other insurance and additional coverages as it may
deem necessary, including, but not limited to, commercial liability insurance
and rent loss insurance. All such insurance shall be included as part of the
Operating Expenses charged to Tenant. Landlord covenants to obtain and maintain
property and liability insurance on the Project in forms and amounts customary
for properties substantially similar to the Project, subject to customary
deductibles. The Project or Building may be included in a blanket policy (in
which case the cost of such insurance allocable to the Project or Building will
be determined by Landlord based upon the insurer's cost calculations).

                  Tenant, at its expense, shall maintain during the Lease Term:
all risk property insurance included in the so-called "Extended Coverage" rider
in Mexico covering the full replacement cost of all property and improvements
installed or placed in the Premises by Tenant at Tenant's expense; and
commercial liability insurance, with a minimum limit of US$1,000,000 per
occurrence and a minimum umbrella limit of US$1,000,000, for a total minimum
combined general liability and umbrella limit of US$2,000,000 (together with
such additional umbrella coverage as Landlord may reasonably require) for
property damage, personal injuries, or deaths of persons occurring in or about
the Premises. Landlord may from time to time require reasonable increases in any
such limits. The commercial liability policies shall name Landlord as an
additional insured, insure on an occurrence and not a claims-made basis, be
issued by insurance companies which are reasonably acceptable to Landlord, not
be cancelable unless 30 days prior written notice shall have been given to
Landlord, contain a hostile fire endorsement and a contractual liability
endorsement and provide primary coverage to Landlord (any policy issued to
Landlord providing duplicate or similar coverage shall be deemed excess over
Tenant's policies). Such policies or certificates thereof shall be delivered to
Landlord by Tenant upon commencement of the Lease Term and upon each renewal of
said insurance.

<PAGE>

                  The all risk property insurance obtained by Landlord and
Tenant shall include a waiver of subrogation by the insurers and all rights
based upon an assignment from its insured, against Landlord or Tenant, their
officers, directors, employees, managers, agents, invitees and contractors, in
connection with any loss or damage thereby insured against. Neither party nor
its officers, directors, employees, managers, agents, invitees or contractors
shall be liable to the other for loss or damage caused by any risk coverable by
all risk property insurance, and each party waives any claims against the other
party, and its officers, directors, employees, managers, agents, invitees and
contractors for such loss or damage. The failure of a party to insure its
property shall not void this waiver. Landlord and its agents, employees and
contractors shall not be liable for, and Tenant hereby waives all claims against
such parties for, business interruption and losses occasioned thereby sustained
by Tenant or any person claiming through Tenant resulting from any accident or
occurrence in or upon the Premises or the Project from any cause whatsoever,
including without limitation, damage caused in whole or in part, directly or
indirectly, by the negligence of Landlord or its agents, employees or
contractors.

                  Tenant and its subtenants, assignees, invitees, employees,
contractors and agents shall not be liable for, and Landlord hereby waives all
claims against Tenant and its subtenants, assignees, invitees, employees,
contractors and agents for damage to property sustained by Landlord or any
person claiming through Landlord resulting from any insurable accident or
occurrence in or upon the Premises or in or about the Project from any cause
whatsoever, including, without limitation, damage caused in whole or in part,
directly or indirectly, by the negligence of Tenant or its subtenants,
assignees, invitees, employees, contractors or agents; provided, however, such
waiver shall only apply to claims in excess of the commercially reasonable
deductible under Landlord's insurance policy.

         10. LANDLORD'S REPAIRS. Landlord shall keep in good repair and shall
maintain and repair, at its expense, the structural soundness of the roof,
foundation, and exterior walls of the Building in good repair, reasonable wear
and tear and uninsured losses and damages caused by Tenant, its agents,
contractors and customers excluded. The term "walls" as used in this Paragraph
10 shall not include windows, glass or plate glass, doors or overhead doors,
special store fronts, dock bumpers, dock plates or levelers, or office entries.
Tenant shall promptly give Landlord written notice of any repair required by
Landlord pursuant to this Paragraph 10, after which Landlord shall have a
reasonable opportunity to repair.

         11. TENANT'S REPAIRS. Landlord, at Tenant's expense as provided in
Paragraph 6, shall maintain in good repair and condition the parking areas and
other common areas of the Building, including, but not limited to driveways,
alleys, landscape and grounds surrounding the Premises. Subject to Landlord's
obligation in Paragraph 10 and subject to Paragraphs 9 and 15, Tenant, at its
expense, shall repair, replace and maintain in good condition all portions of
the Premises and all areas, improvements and systems exclusively serving the
Premises including, without limitation, dock and loading areas, truck doors,
plumbing, water and sewer lines up to points of common connection, fire
sprinklers and fire protection systems, entries, doors, ceilings, windows,
interior walls, and the interior side of demising walls, and heating,
ventilation and air conditioning systems. Such heating, ventilation and air
conditioning systems and other mechanical and building systems serving the
Premises shall be maintained at Tenant's expense pursuant to maintenance service
contracts entered into by Tenant or, at Landlord's election, by Landlord. The
scope of services and contractors under such maintenance contracts shall be
reasonably approved by Landlord. At Landlord's request, Tenant shall enter into
a joint maintenance agreement with any railroad that services the Premises. If
Tenant fails to perform any repair or replacement for which it is responsible,
Landlord may perform such work and be reimbursed by Tenant within 10 days after
demand therefor. Subject to Paragraphs 9 and 15, Tenant shall bear the full cost
of any repair or replacement to any part of the Building or Project that results
from damage caused by Tenant, its agents, contractors, or invitees and any
repair that benefits only the Premises. See Addendum #3.

         12. TENANT-MADE ALTERATIONS AND TRADE FIXTURES. Any alterations,
additions, or improvements made by or on behalf of Tenant to the Premises
("Tenant-Made Alterations") shall be subject to Landlord's prior written
consent, which consent may include conditions. Tenant shall cause, at its
expense, all Tenant-Made Alterations to comply with insurance requirements and
with Legal Requirements and shall construct at its expense any alteration or
modification required by Legal Requirements as a result of any Tenant-Made
Alterations. All Tenant-Made Alterations shall be constructed in a good and
workmanlike manner by contractors reasonably acceptable to Landlord and only
good grades of materials shall be used. All plans and specifications for any
Tenant-Made Alterations shall be submitted to Landlord for its approval.
Landlord may monitor construction of the Tenant-Made Alterations at Tenant's
expense. Tenant shall reimburse Landlord for its third party, out-of-pocket
costs in reviewing plans and specifications and in monitoring construction up to
a maximum amount of $500 per occurrence. Landlord's right to review plans and
specifications and to monitor construction shall be solely for its own benefit,
and Landlord shall have no duty to see that such plans and specifications or
construction comply with applicable Legal Requirements and all laws, codes,
rules and regulations. Tenant shall provide Landlord with the identities and
mailing addresses of all persons performing work or supplying materials, prior
to beginning such construction, and Landlord may post on and about the Premises
notices of non-responsibility pursuant to applicable law. Tenant shall furnish
security or make other arrangements satisfactory to Landlord to assure payment
for the completion of all work free and clear of liens and shall provide
certificates of insurance for worker's compensation and other coverage in
amounts and from an insurance company satisfactory to Landlord protecting
Landlord against liability for personal injury or property damage during
construction. Upon completion of any Tenant-Made Alterations, Tenant shall
deliver to Landlord sworn statements setting forth the names of all contractors
and subcontractors. Upon surrender of the Premises, all Tenant-Made Alterations
and any leasehold improvements constructed by Landlord or Tenant shall remain on
the Premises as Landlord's property, except to the extent Landlord requires
removal at Tenant's expense of any such items or Landlord and Tenant have
otherwise agreed in writing in connection with Landlord's consent to any
Tenant-Made Alterations. Tenant shall repair any damage caused by such removal.

                  Tenant, at its own cost and expense and without Landlord's
prior approval, may erect such shelves, bins, machinery and trade fixtures
(collectively "Trade Fixtures") in the ordinary course of its business, provided
that such items do not alter the basic character of the Premises, do not
overload or damage the Premises, and may be removed without injury to the
Premises, and the construction, erection, and installation thereof complies with
all Legal Requirements and with Landlord's requirements set forth above. Tenant
shall remove its Trade Fixtures and shall repair any damage caused by such
removal.

         13. SIGNS. Tenant shall not make any changes to the exterior of the
Premises, install any exterior lights, decorations, balloons, flags, pennants,
banners, or painting, or erect or install any signs, windows or door lettering,
placards, decorations, or advertising media of any type which can be viewed from
the exterior of the Premises, without Landlord's prior written consent. Upon
surrender or vacation of the Premises, Tenant shall have removed all signs and
repair, paint, and/or replace the Building facia surface to which its signs are
attached. Tenant shall obtain all applicable governmental permits and approvals
for sign and exterior treatments. All signs, decorations, advertising media,
blinds, draperies and other window treatment or bars or other security
installations visible from outside the Premises shall be subject to Landlord's
prior written approval and conform in all respects to Landlord's requirements
and to Legal Requirements. See Addendum #4.

         14. PARKING. Tenant shall be entitled to park in common with other
tenants of the Project in those areas designated for nonreserved parking.
Landlord may allocate parking spaces among Tenant and other tenants in the
Project if Landlord determines that such parking facilities are becoming
crowded. Landlord shall not be responsible for enforcing Tenant's parking rights
against any third parties.

         15. RESTORATION. If at any time during the Lease Term the Premises are
damaged by a fire or other casualty, Landlord shall notify Tenant within 60 days
after such damage as to the amount of time Landlord reasonably estimates it will
take to restore the Premises. If the restoration time is estimated to exceed 6
months, either Landlord or Tenant may elect to terminate this Lease upon notice
to the other party given no later than 30 days after Landlord's notice. If
neither party elects to terminate this Lease or if Landlord estimates that
restoration will take 6 months or less, then, subject to receipt of sufficient
insurance proceeds, Landlord shall promptly restore the Premises excluding the
improvements installed by Tenant or by Landlord and paid by Tenant, subject to
delays arising from the collection of insurance proceeds or from Force Majeure
events. Tenant at Tenant's expense shall promptly perform, subject to delays
arising from the collection of insurance proceeds, or from Force Majeure events,
all repairs or restoration not required to be done by Landlord and shall
promptly re-enter the Premises and commence doing business in accordance with
this Lease. Notwithstanding the foregoing, either party may terminate this Lease
if the Premises are damaged during the last year of the Lease Term and Landlord
reasonably estimates that it will take more than one month to repair such
damage. Base Rent and Operating Expenses shall be abated for the period of
repair and restoration in the proportion which the area of the Premises, if any,
which is not usable by Tenant bears to the total area of the Premises. Such
abatement shall be the sole remedy of Tenant, and except as provided herein,
Tenant waives any right to terminate the Lease by reason of damage or casualty
loss.

                                      -7-
<PAGE>

         16. CONDEMNATION. If any part of the Premises or the Project should be
taken for any public or quasi-public use under governmental law, ordinance, or
regulation, or by right of eminent domain, or by private purchase in lieu
thereof (a "Taking" or "Taken"), and the Taking would prevent or materially
interfere with Tenant's use of the Premises or in Landlord's judgment would
materially interfere with or impair its ownership or operation of the Project,
then upon written notice by Landlord this Lease shall terminate and Base Rent
shall be apportioned as of said date. If part of the Premises shall be Taken,
and this Lease is not terminated as provided above, the Base Rent payable
hereunder during the unexpired Lease Term shall be reduced to such extent as may
be fair and reasonable under the circumstances. In the event of any such Taking,
Landlord shall be entitled to receive the entire price or award from any such
Taking without any payment to Tenant, and Tenant hereby assigns to Landlord
Tenant's interest, if any, in such award. Tenant shall have the right, to the
extent that same shall not diminish Landlord's award, to make a separate claim
against the condemning authority (but not Landlord) for such compensation as may
be separately awarded or recoverable by Tenant for moving expenses and damage to
Tenant's Trade Fixtures, if a separate award for such items is made to Tenant.

         17. ASSIGNMENT AND SUBLETTING. Without Landlord's prior written
consent, Tenant shall not assign this Lease or sublease the Premises or any part
thereof or mortgage, pledge, or hypothecate its leasehold interest or grant any
concession or license within the Premises and any attempt to do any of the
foregoing shall be void and of no effect. For purposes of this paragraph, a
transfer of the ownership interests controlling Tenant shall be deemed an
assignment of this Lease unless such ownership interests are publicly traded.
Notwithstanding the above, Tenant may assign or sublet the Premises, or any part
thereof, to any entity controlling Tenant, controlled by Tenant or under common
control with Tenant (a "Tenant Affiliate"), without the prior written consent of
Landlord. Tenant shall reimburse Landlord for all of Landlord's reasonable
out-of-pocket expenses in connection with any assignment or sublease. Upon
Landlord's receipt of Tenant's written notice of a desire to assign or sublet
the Premises, or any part thereof (other than to a Tenant Affiliate), Landlord
may, by giving written notice to Tenant within 30 days after receipt of Tenant's
notice, terminate this Lease with respect to the space described in Tenant's
notice, as of the date specified in Tenant's notice for the commencement of the
proposed assignment or sublease.

                  Notwithstanding any assignment or subletting, Tenant and any
guarantor or surety of Tenant's obligations under this Lease shall at all times
remain fully responsible and liable for the payment of the rent and for
compliance with all of Tenant's other obligations under this Lease. In the event
that the rent due and payable by a sublessee or assignee (or a combination of
the rental payable under such sublease or assignment plus any bonus or other
consideration therefor or incident thereto) exceeds the rental payable under
this Lease, then Tenant shall be bound and obligated to pay Landlord as
additional rent hereunder 50% of all such excess rental and other excess
consideration within 10 days following receipt thereof by Tenant.

                  If this Lease be assigned or if the Premises be subleased
(whether in whole or in part) or in the event of the mortgage, pledge, or
hypothecation of Tenant's leasehold interest or grant of any concession or
license within the Premises or if the Premises be occupied in whole or in part
by anyone other than Tenant, then upon a default by Tenant hereunder Landlord
may collect rent from the assignee, sublessee, mortgagee, pledgee, party to whom
the leasehold interest was hypothecated, concessionee or licensee or other
occupant and, except to the extent set forth in the preceding paragraph, apply
the amount collected to the next rent payable hereunder; and all such rentals
collected by Tenant shall be held in deposit for Landlord and immediately
forwarded to Landlord. No such transaction or collection of rent or application
thereof by Landlord, however, shall be deemed a waiver of these provisions or a
release of Tenant from the further performance by Tenant of its covenants,
duties, or obligations hereunder.

         18. INDEMNIFICATION. Except for the negligence of Landlord, its agents,
employees or contractors, and to the extent permitted by law, Tenant agrees to
indemnify, defend and hold harmless Landlord, and Landlord's agents, employees
and contractors, from and against any and all losses, liabilities, damages,
costs and expenses (including attorney's fees) resulting from claims by third
parties for injuries to any person and damage to or theft or misappropriation or
loss of property occurring in or about the Project and arising from the use and
occupancy of the Premises by Tenant, its subtenants, assignees, invitees,
employees, contractors and agents, or from any activity, work, or thing done,
permitted or suffered by Tenant in or about the Premises or due to any other act
or omission of Tenant, its subtenants, assignees, invitees, employees,
contractors and agents. The furnishing of insurance required hereunder shall not
be deemed to limit Tenant's obligations under this Paragraph 18.

                                      -8-
<PAGE>

         19. INSPECTION AND ACCESS. Landlord and its agents, representatives,
and contractors may enter the Premises at any reasonable time upon reasonable
prior notice (except in the case of an emergency) to inspect the Premises and to
make such repairs as may be required or permitted pursuant to this Lease and for
any other business purpose. Upon Tenant's request, Landlord shall provide Tenant
with the contractor's name(s) performing such repairs. Landlord and Landlord's
representatives may enter the Premises during business hours upon reasonable
prior notice for the purpose of showing the Premises to prospective purchasers
and, during the last year of the Lease Term, to prospective tenants. Landlord
may erect a suitable sign on the Premises stating the Premises are available to
rent or that the Project is available for sale. Landlord may grant easements,
make public dedications, designate common areas and create restrictions on or
about the Premises, provided that no such easement, dedication, designation or
restriction materially interferes with Tenant's use or occupancy of the Premises
or Tenant's quiet enjoyment rights as set forth below. At Landlord's request,
Tenant shall execute such instruments as may be necessary for such easements,
dedications or restrictions.

         20. QUIET ENJOYMENT. If Tenant shall perform all of the covenants and
agreements herein required to be performed by Tenant, Tenant shall, subject to
the terms of this Lease, at all times during the Lease Term, have peaceful and
quiet enjoyment of the Premises against any person claiming by, through or under
Landlord.

         21. SURRENDER. Upon termination of the Lease Term or earlier
termination of Tenant's right of possession, Tenant shall surrender the Premises
to Landlord in the same condition as received, broom clean, ordinary wear and
tear and casualty loss and condemnation covered by Paragraphs 15 and 16
excepted. Any Trade Fixtures, Tenant-Made Alterations and property not so
removed by Tenant as permitted or required herein shall be deemed abandoned and
may be stored, removed, and disposed of by Landlord at Tenant's expense, and
Tenant waives all claims against Landlord for any damages resulting from
Landlord's retention and disposition of such property. All obligations of Tenant
hereunder not fully performed as of the termination of the Lease Term shall
survive the termination of the Lease Term, including without limitation,
indemnity obligations, payment obligations with respect to Operating Expenses
and obligations concerning the condition and repair of the Premises. See
Addendum #5.

         22. HOLDING OVER. If Tenant retains possession of the Premises after
the termination of the Lease Term, unless otherwise agreed in writing, such
possession shall be subject to immediate termination by Landlord at any time,
and all of the other terms and provisions of this Lease (excluding any expansion
or renewal option or other similar right or option) shall be applicable during
such holdover period, except that Tenant shall, in addition to all other
payments required hereunder, pay Landlord from time to time, upon demand, as
Base Rent for the holdover period, an amount equal to 150% of the Base Rent in
effect on the termination date, computed on a monthly basis for each month or
part thereof during such holding over. In addition, Tenant shall be liable for
all damages incurred by Landlord as a result of such holding over. No holding
over by Tenant, whether with or without consent of Landlord, shall operate to
extend this Lease except as otherwise expressly provided, and this Paragraph 22
shall not be construed as consent for Tenant to retain possession of the
Premises.

         23. EVENTS OF DEFAULT. Each of the following events shall be an event
of default ("Event of Default") by Tenant under this Lease:

                  (i) Tenant shall fail to pay any installment of Base Rent or
         any other payment required herein when due, and such failure shall
         continue for a period of 5 days from the date such payment was due.

                  (ii) Tenant or any guarantor or surety of Tenant's obligations
         hereunder shall (A) make a general assignment for the benefit of
         creditors; (B) commence any case, proceeding or other action seeking to
         have an order for relief entered on its behalf as a debtor or to
         adjudicate it bankrupt or insolvent, or seeking reorganization,
         arrangement, adjustment, liquidation, dissolution or composition of it
         or its debts or seeking appointment of a receiver, trustee, custodian
         or other similar official for it or for all or of any substantial part
         of its property (collectively a "proceeding for relief"); (C) become
         the subject of any proceeding for relief which is not dismissed within
         60 days of its filing or entry; or (D) be dissolved or otherwise fail
         to maintain its legal existence (if Tenant, guarantor or surety is a
         corporation, partnership or other entity).

                                      -9-
<PAGE>

                  (iii) Any insurance required to be maintained by Tenant
         pursuant to this Lease is not obtained or shall be canceled or
         terminated or shall expire, except, in each case, as permitted in this
         Lease.

                  (iv) Tenant shall not occupy or shall vacate the Premises or
         shall fail to continuously operate its business at the Premises for the
         permitted use set forth herein, whether or not Tenant is in monetary or
         other default under this Lease. Notwithstanding the foregoing, Tenant's
         vacating of the Premises shall not constitute an Event of Default if,
         prior to vacating the Premises, Tenant has made arrangements reasonably
         acceptable to Landlord to (a) insure that Tenant's insurance for the
         Premises will not be voided or cancelled with respect to the Premises
         as a result of such vacancy, (b) insure that the Premises are secured
         and not subject to vandalism, and (c) insure that the Premises will be
         properly maintained after such vacation. Tenant shall inspect the
         Premises at least once each month and report monthly in writing to
         Landlord on the condition of the Premises.

                  (v) Tenant shall attempt or there shall occur any assignment,
         subleasing or other transfer of Tenant's interest in or with respect to
         this Lease except as otherwise permitted in this Lease.

                  (vi) Tenant shall fail to comply with any provision of this
         Lease other than those specifically referred to in this Paragraph 23,
         and such default shall continue for more than 30 days after Landlord
         shall have given Tenant written notice of such default.

         24. LANDLORD'S REMEDIES. Upon the occurrence of an Event of Default
Landlord shall have all of the remedies against Tenant permitted by law
including, without limitation, the right to (i) terminate this Lease and recover
possession of the Property or (ii) seek specific performance of this Lease. In
either event, Landlord shall also be entitled to recover from Tenant, as
liquidated damages, the balance of the Base Rent and all other amounts accrued
or to accrue hereunder for the remainder of the unexpired portion of the Term
discounted to present value at the rate of eight percent (8%) per annum, all of
which amount shall be due and payable upon demand.

         25. TENANT'S REMEDIES/LIMITATION OF LIABILITY. Landlord shall not be in
default hereunder unless Landlord fails to perform any of its obligations
hereunder within 30 days after written notice from Tenant specifying such
failure (unless such performance will, due to the nature of the obligation,
require a period of time in excess of 30 days, then after such period of time as
is reasonably necessary). All obligations of Landlord hereunder shall be
construed as covenants, not conditions. All obligations of Landlord under this
Lease will be binding upon Landlord only during the period of its ownership of
the Premises and not thereafter. The term "Landlord" in this Lease shall mean
only the owner, for the time being of the Premises, and in the event of the
transfer by such owner of its interest in the Premises, such owner shall
thereupon be released and discharged from all obligations of Landlord thereafter
accruing, but such obligations shall be binding during the Lease Term upon each
new owner for the duration of such owner's ownership. Any liability of Landlord
under this Lease shall be limited solely to its interest in the Project, and in
no event shall any personal liability be asserted against Landlord in connection
with this Lease nor shall any recourse be had to any other property or assets of
Landlord. Landlord's interest in the Project shall be deemed to include: (i) the
rents or other income from the Project received by Landlord after Tenant obtains
a final judgment against Landlord, (ii) the net proceeds received by Landlord
from the sale or other disposition of all or any part of Landlord's right, title
and interest in the Project after Tenant obtains a final judgment against
Landlord, (iii) the net proceeds received by Landlord from any condemnation or
conveyance in lieu of condemnation of all or any portion of the Project after
Tenant obtains a final judgment against Landlord, and (iv) the net proceeds of
insurance received by Landlord from any casualty loss of all or any portion of
the Project after Tenant obtains a final judgment against Landlord.

         26. TRANSLATION. This Agreement, in its original form, is prepared in
both Spanish and English. Landlord shall arrange for such Spanish translation
and shall provide a copy of said translation to Tenant. In the event of any
conflict in the translation between the Spanish version and the English version
of the Lease, the English version of the Lease shall control.

                                      -10-
<PAGE>

         27. ESTOPPEL CERTIFICATES. Tenant agrees, from time to time, within 10
days after request of Landlord, to execute and deliver to Landlord, or
Landlord's designee, any estoppel certificate requested by Landlord, stating
that this Lease is in full force and effect, the date to which rent has been
paid, that Landlord is not in default hereunder (or specifying in detail the
nature of Landlord's default), the termination date of this Lease and such other
matters pertaining to this Lease as may be requested by Landlord. Tenant's
obligation to furnish each estoppel certificate in a timely fashion is a
material inducement for Landlord's execution of this Lease. No cure or grace
period provided in this Lease shall apply to Tenant's obligations to timely
deliver an estoppel certificate.

         28. ENVIRONMENTAL REQUIREMENTS. Except for Hazardous Material contained
in products used by Tenant in de minimis quantities for ordinary cleaning and
office purposes and except for Hazardous Materials as permitted pursuant to the
provisions of Addendum 8 attached hereto, Tenant shall not permit or cause any
party to bring any Hazardous Material upon the Premises or transport, store,
use, generate, manufacture or release any Hazardous Material in or about the
Premises without Landlord's prior written consent. Tenant, at its sole cost and
expense, shall operate its business in the Premises in strict compliance with
all Environmental Requirements and shall remediate in a manner satisfactory to
Landlord any Hazardous Materials released on or from the Project by Tenant, its
agents, employees, contractors, subtenants or invitees. Tenant shall complete
and certify to disclosure statements as requested by Landlord from time to time
relating to Tenant's transportation, storage, use, generation, manufacture or
release of Hazardous Materials on the Premises. The term "Environmental
Requirements" means all applicable present and future statutes, laws,
regulations, ordinances, rules, codes, judgments, orders or other similar
enactments of any governmental authority or agency regulating or relating to
health, safety, or environmental conditions on, under, or about the Premises or
the environment, including without limitation, the General Law of Ecological
Balance and Environmental Protection, Regulations of the General Law of
Ecological Balance and Environmental Protection Regarding Environmental Impact,
Prevention and Control of Air Pollution and of Hazardous Waste, Official Mexican
Standards, International Treaties and the Guidelines issued by the National
Institute of Ecology of Mexico and all state and local counterparts thereto, and
any regulations or policies promulgated or issued thereunder. The term
"Hazardous Materials" means and includes any substance, material, waste,
pollutant, or contaminant listed or defined as hazardous or toxic, under any
Environmental Requirements, asbestos and petroleum, including crude oil or any
fraction thereof, natural gas liquids, liquified natural gas, or synthetic gas
usable for fuel (or mixtures of natural gas and such synthetic gas). As defined
in Environmental Requirements, Tenant is and shall be deemed to be the
"operator" of Tenant's "facility" and the "owner" of all Hazardous Materials
brought on the Premises by Tenant, its agents, employees, contractors or
invitees, and the wastes, by-products, or residues generated, resulting, or
produced therefrom.

                  Tenant shall indemnify, defend, and hold Landlord harmless
from and against any and all losses (including, without limitation, diminution
in value of the Premises or the Project and loss of rental income from the
Project), claims, demands, actions, suits, damages (including, without
limitation, punitive damages), expenses (including, without limitation,
remediation, removal, repair, corrective action, or cleanup expenses), and costs
(including, without limitation, actual attorneys' fees, consultant fees or
expert fees and including, without limitation, removal or management of any
asbestos brought into the property or disturbed in breach of the requirements of
this Paragraph 28, regardless of whether such removal or management is required
by law) which are brought or recoverable against, or suffered or incurred by
Landlord, directly or indirectly, as a result of any release of Hazardous
Materials for which Tenant is obligated to remediate as provided above or any
other breach of the requirements under this Paragraph 28 by Tenant, its agents,
employees, contractors, subtenants, assignees or invitees, regardless of whether
Tenant had knowledge of such noncompliance. The obligations of Tenant under this
Paragraph 28 shall survive any termination of this Lease.

                  Landlord shall have access to, and a right to perform
inspections and tests of the Premises to determine Tenant's compliance with
Environmental Requirements, its obligations under this Paragraph 28, or the
environmental condition of the Premises. Access shall be granted to Landlord
upon Landlord's prior notice to Tenant and at such times so as to minimize, so
far as may be reasonable under the circumstances, any disturbance to Tenant's
operations. Such inspections and tests shall be conducted at Landlord's expense,
unless such inspections or tests reveal that Tenant has not complied with any
Environmental Requirement, in which case Tenant shall reimburse Landlord for the
reasonable cost of such inspection and tests. Landlord's receipt of or
satisfaction with any environmental assessment in no way waives any rights that
Landlord holds against Tenant.

invalid or unenforceable under present or future laws, then and in that event,
it is the intention of the parties hereto that the remainder of this Lease shall
not be affected thereby. It is also the intention of the parties to this Lease
that in lieu of each clause or provision of this Lease that is illegal, invalid
or unenforceable, there be added, as a part of this Lease, a clause or provision
as similar in terms to such illegal, invalid or unenforceable clause or
provision as may be possible and be legal, valid and enforceable.

         34. BROKERS. Tenant represents and warrants that it has dealt with no
broker, agent or other person in connection with this transaction and that no
broker, agent or other person brought about this transaction, other than the
broker, if any, set forth on the first page of this Lease, and Tenant agrees to
indemnify and hold Landlord harmless from and against any claims by any other
broker, agent or other person claiming a commission or other form of
compensation by virtue of having dealt with Tenant with regard to this leasing
transaction.

         35. LIMITATION OF LIABILITY OF TRUSTEES, SHAREHOLDERS AND OFFICERS OF
LANDLORD: Any obligation or liability whatsoever of Landlord, of any of its
parents, subsidiaries or affiliates (collectively "Landlord"), which may arise
at any time under this Lease or any obligation or liability which may be insured
by it pursuant to any other instrument, transaction, or undertaking contemplated

enforcement thereof be had to the property of, its trustees, directors,
shareholders, officers, employees or agents, regardless of whether such
obligation or liability is in the nature of contract, tort, or otherwise, and
any liabilities shall be limited solely to Landlord's interest in the Property,
and no recourse shall be had to any other property or assets of Landlord.

                  LIMITATION OF LIABILITY OF SHAREHOLDERS AND OFFICERS OF

subsidiaries or affiliates (collectively "Tenant"), which may arise at any time
under this Lease or any obligation or liability which may be insured by it

hereby shall not be personally binding upon, nor shall resort for the
enforcement thereof be had to the property of, its directors, shareholders,
officers, employees or agents, regardless of whether such obligation or
liability is in the nature of contract, tort, or otherwise.

         36. MISCELLANEOUS. (a) Any payments or charges due from Tenant to
Landlord hereunder shall be considered rent for all purposes of this Lease.

         (b) If and when included within the term "Tenant," as used in this
instrument, there is more than one person, firm or corporation, each shall be
jointly and severally liable for the obligations of Tenant.

         (c) All notices required or permitted to be given under this Lease
shall be in writing and shall be sent by a reputable national overnight courier
service, postage prepaid, or by hand delivery addressed to the parties at their
addresses below, and with a copy sent to Landlord at 14100 EAST 35TH PLACE,

otherwise required by law, Landlord retains the absolute right to withhold any
consent or approval.

or 12 percent per year. It is expressly the intent of Landlord and Tenant at all
times to comply with applicable law governing the maximum rate or amount of any
interest payable on or in connection with this Lease. If applicable law is ever
judicially interpreted so as to render usurious any interest called for under
this Lease, or contracted for, charged, taken , reserved, or received with
respect to this Lease, then it is Landlord's and Tenant's express intent that
all excess amounts theretofore collected by Landlord be credited on the
applicable obligation (or, if the obligation has been or would thereby be paid
in full, refunded to Tenant), and the provisions of this Lease immediately shall
be deemed reformed and the amounts thereafter collectible hereunder reduced,
without the necessity of the execution of any new document, so as to comply with
the applicable law, but so as to permit the recovery of the fullest amount
otherwise called for hereunder.

         (i) Construction, interpretation and enforcement of this Lease shall be
governed by the laws of the state in which the Project is located, excluding any
principles of conflicts of laws and the parties submit to the jurisdiction of
the competent courts of the corresponding state, waiving hereby the jurisdiction
of any other court to which they may be subject by virtue of their present or
future domiciles or otherwise.

such exhibits or addenda and the terms of this Lease, such exhibits or addenda
shall control.

         37. WAIVER OF RIGHT OF FIRST OFFER/RIGHT OF FIRST REFUSAL. Tenant

Premises and/or the Building and/or the land over other possible tenants and
buyer of the Premises. Further, except as otherwise expressly set forth in this

                                                      GUARANTY

         The undersigned, Wilson Greatbatch Technologies, Inc. ("Guarantor"),
being the owner and holder of a majority of the issued and outstanding capital
stock of the Tenant, hereafter named, in consideration of the leasing of the
leased premises described in that certain Lease (the "Lease"), dated April 22,
2004, between Tijuana Mexico Investment I LLC, as Landlord (the "Landlord"), and
Wilson Greatbatch Technologies, Inc., as Tenant (the "Tenant"), does hereby
covenant and agree as follows:

     A.   Guarantor does hereby guarantee the full, faithful and timely payment
          and performance by Tenant of all of the payments, covenants and other
          obligations of Tenant under or pursuant to the Lease. If Tenant shall
          default at any time in the payment of any rent or any other sums,
          costs or charges whatsoever including, without limitation, late
          charges, additional rent (however termed or defined), court costs and
          attorneys' fees, or in the performance of all warranties,
          representations and any of the other covenants and obligations of
          Tenant, under or pursuant to the Lease, then Guarantor, at its
          expense, shall on demand of Landlord fully and promptly, and well and
          truly, pay all rent, sums, costs and charges to be paid by Tenant, and
          perform all the other covenants and obligations to be performed by
          Tenant, under or pursuant to the Lease, and in addition shall on
          Landlord's demand pay to Landlord any and all sums due to Landlord,
          including, without limitation, all interest on past due obligations of
          Tenant, costs advanced by Landlord, and damages and all expenses
          (including attorneys' fees and litigation costs), that may arise in
          consequence of Tenant's default. Guarantor hereby waives (a) notice of
          acceptance hereof (which acceptance is conclusively presumed by
          delivery to Landlord); (b) grace, demand, presentment and protest with
          respect to the obligations and liabilities guaranteed hereunder or to
          any instrument, agreement or document evidencing or creating same; (c)
          notice of grace, demand, presentment and protest; (d) notice of
          non-payment or other defaults, of intention to accelerate and of
          acceleration of the obligations and liabilities guaranteed hereunder;
          (e) notice of and/or any right to consent or object to the assignment
          of any interest in the Lease or the obligations and liabilities
          guaranteed hereunder; (f) the renewal, extension, amendment and/or
          modification of any of the terms and provisions of the Lease; (g)
          filing of suit and diligence by Landlord in collection or enforcement
          of the obligations and liabilities guaranteed hereunder; and (h) any
          other notice regarding the obligations and liabilities guaranteed
          hereunder.

     B.   The obligations of Guarantor hereunder are independent of the
          obligations of Tenant. A separate action or actions may, at Landlord's
          option, be brought and prosecuted against Guarantor, whether or not
          any action is first or subsequently brought against Tenant or any
          other guarantor, or whether or not Tenant or any other guarantor is
          joined in, or made a party to, any such action, and Guarantor may, at
          Landlord's option, be joined in any action or proceeding commenced by
          Landlord against Tenant or any other guarantor arising out of, in
          connection with or based upon the Lease. Guarantor waives any right or
          claim to require Landlord to proceed against Tenant or any other
          guarantor or pursue any other remedy in Landlord's power whatsoever,
          whether arising from any documents executed by Tenant, any common law,
          applicable statute or otherwise, any right to complain of delay in the
          enforcement of or refusal to enforce Landlord's rights under the
          Lease, any demand by Landlord and/or prior action by Landlord of any
          nature whatsoever against Tenant, or otherwise. Guarantor further
          agrees not to assert any defense (other than payment) available to
          Tenant against Landlord with regard to the obligations and liabilities
          guaranteed hereunder, any defense based upon an election of remedies
          of any type, any defense based on any duty of Landlord to disclose
          information of any type to the undersigned regarding Tenant or the
          obligations and liabilities guaranteed hereunder. Guarantor waives any
          defense or right arising by reason of any disability or lack of
          authority or power of Tenant and shall remain liable hereunder if
          Tenant or any other party shall not be liable under the Lease for such
          reason.

                                      -17-
<PAGE>

     C.   The undersigned agrees that Landlord may at any time, and from time to
          time, at Landlord's discretion and with or without notice or
          consideration to or consent from any party: (a) release any party
          liable on the Lease, including without limitation, Tenant and any
          other guarantor; and (b) extend, renew, rearrange, modify or amend any
          of the terms and provisions of the Lease. Any of such actions may be
          taken without impairing or diminishing the obligations and liabilities
          of Guarantor hereunder. This Guaranty shall remain and continue in
          full force and effect and shall not be discharged in whole or in part
          notwithstanding (whether prior or subsequent to the execution hereof)
          any alteration, renewal, extension, modification, amendment or
          assignment of, or subletting, concession, franchising, licensing or
          permitting under, the Lease. Guarantor hereby waives notices of any of
          the foregoing, and agrees that the liability of the undersigned
          hereunder shall be based upon the obligations of Tenant set forth in
          the Lease as the same may be altered, renewed, extended, modified,
          amended or assigned. For the purpose of this Guaranty and the
          obligations and liabilities of the undersigned hereunder, "Tenant"
          shall be deemed to include any and all concessionaires, licensees,
          franchisees, department operators, assignees, subtenants, permittees
          or others directly or indirectly operating or conducting a business in
          or from the leased premises, as fully as if any of the same were the
          named Tenant under the Lease.

     D.   The liability of Guarantor shall not be impaired, reduced or in any
          way affected by: (a) Landlord's failure, refusal, or neglect to
          collect or enforce the obligations and liabilities guaranteed
          hereunder, by way of, without limitation, any indulgence, forbearance,
          compromise, settlement or waiver of performance which may be extended
          to Tenant by Landlord or agreed upon by Landlord and Tenant; (b) any
          termination of the Lease to the extent that Tenant thereafter
          continues to be liable; (c) any sublease of the space covered by the
          Lease or any assignment of the Lease by any means or to any entity or
          person whatsoever regardless of whether Tenant thereafter continues to
          be liable; (d) loss or subordination of any other guaranty, if any, or
          by the existence of any indebtedness of Tenant to Landlord other than
          the indebtedness guaranteed hereby; (e) the taking of any security or
          any other guaranty for the obligations and liabilities guaranteed
          hereby in addition to the guaranty presently existing; (f) the
          misapplication of collateral at any time given as security for
          Tenant's obligations (including other guaranties).

     E.   The obligations of Guarantor hereunder shall not be reduced, impaired
          or in any way affected by: (a) receivership, insolvency, bankruptcy or
          other proceedings, whether in or outside of Mexico, affecting the
          Tenant or any of the Tenant's assets; (b) receivership, insolvency,
          bankruptcy or other proceedings affecting the undersigned or any of
          the undersigned's assets; or (c) the release or discharge of Tenant
          from the Lease or any other indebtedness of the Tenant to Landlord or
          from the performance of any obligation contained in the Lease or other
          instrument issued in connection with, evidencing or securing any
          indebtedness guaranteed by this instrument, whether occurring by
          reason of law or any other cause, whether similar or dissimilar to the
          foregoing. This Guaranty shall continue to be effective or be
          reinstated, as the case may be, if at any time any payment of any of
          the indebtedness guaranteed hereby is rescinded or must otherwise be
          returned by Landlord upon the insolvency, bankruptcy or reorganization
          of Tenant or otherwise.

     F.   Guarantor hereby fully subordinates the payment of all indebtedness
          owing to the undersigned by Tenant (including principal and interest)
          to the prior payment of all indebtedness of Tenant to Landlord
          (including, without limitation, interest accruing on any such
          indebtedness after any insolvency or reorganization proceeding as to
          Tenant) and agrees not to accept any payment on the same until payment
          in full of the obligations and liabilities guaranteed hereunder, and
          not to attempt to set off or reduce any obligations hereunder because
          of such indebtedness. Until all of the obligations and liabilities
          guaranteed hereunder shall have been paid or performed in full,
          Guarantor shall have no right of subrogation or any other right to
          enforce any remedy which Landlord now has or may hereafter have
          against Tenant.

     G.   All payments to be made and obligations to be performed hereunder
          shall be payable or performable at the offices of Landlord in The
          United States of America. If it becomes necessary for Landlord to
          enforce this Guaranty by legal action, the undersigned hereby waives
          the right to be sued in the Country of Mexico or any political
          subdivision thereof, and also waives the right to be sued in the
          county or state of Guarantor's residence and agrees to submit to the
          jurisdiction and venue of the appropriate federal, state or other
          governmental court in such county and state within the United States
          of America where Landlord maintains an office. Guarantor
          unconditionally agrees to pay Landlord's collection expenses
          (including, without limitation, court costs and reasonable attorneys'
          fees) if enforcement hereof is placed in the hands of an attorney,
          including, but expressly not limited to, enforcement by suit or
          through probate, bankruptcy or any judicial proceedings.

     H.   If Guarantor is or becomes liable for any indebtedness of Tenant to
          Landlord other than the obligations and liabilities guaranteed
          hereunder by any means other than under this Guaranty, such liability
          shall not be impaired, reduced or affected in any manner hereby but
          shall have all and the same force and effect it would have had if this
          Guaranty had not existed, and Guarantor's liability hereunder shall
          not be impaired, reduced or affected in any manner thereby.

                                      -18-

     I.   All rights of Landlord hereunder or otherwise arising under any
          documents executed in connection with the obligations and liabilities
          guaranteed hereunder are separate and cumulative and may be pursued
          separately, successively or concurrently, or not pursued, without
          affecting or limiting any other right of Landlord and without
          affecting or impairing the liability of the undersigned.

     J.   Notwithstanding any other provisions herein contained, no provision of
          this Guaranty shall require or permit the collection from the
          undersigned of interest in excess of the maximum rate or amount that
          such guarantor may be required or permitted to pay to Landlord
          pursuant to applicable law and as to which such guarantor could
          successfully assert the claim or defense of usury.

     K.   This Guaranty is intended for and shall inure to the benefit of
          Landlord and each and every person who shall from time to time be or
          become the legal or equitable owner or holder of all or any part of
          the Lease and/or the obligations and liabilities guaranteed hereunder,
          and each and every reference herein to "Landlord" shall include and
          refer to each and every successor or assignee of Landlord at any time
          holding or owning any part of or interest in any part of the Lease
          and/or the obligations and liabilities guaranteed hereunder. This
          Guaranty shall be assignable or transferable with the same force and
          effect, and to the same extent, that the Lease and/or the obligations
          and liabilities guaranteed hereunder are assignable or transferable,
          it being understood and stipulated that upon assignment or transfer by
          Landlord of the Lease and/or any of the obligations and liabilities
          guaranteed hereunder, the legal holder or owner thereof (or a part
          thereof or interest therein thus transferred or assigned) shall
          (except as otherwise stipulated by Landlord in its assignment) have
          and may exercise all of the rights granted to Landlord under this
          Guaranty to the extent of that part of or interest in the obligations
          and liabilities guaranteed hereunder thus assigned or transferred.

     L.   Any notice or demand to Guarantor in connection herewith may be given
          and shall conclusively be deemed to have been given and received upon
          deposit thereof in writing, in the U.S. Mails, duly stamped and
          addressed to the undersigned at the address shown below. Guarantor
          shall have the right to designate from time to time another address
          for purposes of this instrument by written notice to Landlord sent by
          United States mail, certified mail, return receipt requested. Actual
          notice or demand, however given or received, shall always be
          effective. The provisions of this Paragraph L shall not be construed
          to affect or impair any waiver of notice or demand herein provided or
          to require giving of notice or demand to or upon the undersigned in
          any situation or for any reason.

     M.   Landlord may apply any payments received from any source against that
          portion of the obligations and liabilities guaranteed hereunder in
          such priority and fashion as Landlord may deem appropriate.

     N.   The payment by Guarantor of any amount pursuant to this Guaranty shall
          not, without Landlord's consent, entitle the undersigned (whether by
          way of subrogation or otherwise) to a right of possession of, or to
          any other right, title or interest in, the premises covered by the
          Lease.

     O.   If this Guaranty is signed by more than one party, their obligations
          shall be joint and several, and the release of one of such guarantors
          shall not release any other of such guarantors.

     P.   Neuter terms should also refer, where applicable, to the feminine
          gender and the masculine gender; the singular reference shall also
          include the plural of any word if the context so requires.

     Q.   This Guaranty shall be applicable to and binding upon the heirs,
          executors, administrators, representatives, successors and assigns of
          Guarantor.

     R.   In the event that Landlord should institute any suit against Guarantor
          for violation of or to enforce any of the covenants or conditions of
          this Guaranty or to enforce any right of Landlord hereunder, or should
          Guarantor institute any suit against Landlord arising out of or in
          connection with this Guaranty, or should either party institute a suit
          against the other for a declaration of rights hereunder, or should
          either party intervene in any suit in which the other is a party to
          enforce or protect its interest or rights hereunder, the prevailing
          party in any such suit shall be entitled to the fees of its
          attorney(s) in the reasonable amount thereof, to be determined by the
          court and taxed as a part of the costs therein.

                                      -19-

     S.   The execution of this Guaranty prior to execution of the Lease shall
          not invalidate this Guaranty or lessen the obligations of Guarantor(s)
          hereunder.

     T.   This Guaranty is made pursuant to, and shall be interpreted and
          applied in accordance with, the laws of the State of Texas.

     U.   This Guaranty shall be irrevocable and shall remain in full force and
          effect for so long as any obligations may remain in connection with
          this Lease.

     V.   This Guaranty is a guaranty of payment and performance and not merely
          a guaranty of collection.

     W.   Guarantor understands and agrees that this Guaranty is a material
          factor and inducement to Landlord in entering into the Lease and that
          absent such Guaranty, Landlord would not have entered into this Lease.

     X.   This instrument may not be changed, modified, discharged or terminated
          orally or in any manner other than by an agreement in writing signed
          by Guarantor and the Landlord.

     Y.   Guarantor and Landlord waive any right to have a jury participate in
          resolving any dispute, whether sounding in contract, tort, or
          otherwise, between Landlord and Guarantor arising out of this Guaranty
          or any other document or instrument executed in connection herewith or
          any transaction related to this Guaranty.

         IN WITNESS WHEREOF, the undersigned has executed this Guaranty this 19
day of MARCH, 2004.

                                   ALLOWANCE

                  ATTACHED TO AND A PART OF THE LEASE AGREEMENT
                          DATED APRIL 22, 2004, BETWEEN

                         TIJUANA MEXICO INVESTMENT I LLC
                                       and

                      WILSON GREATBATCH TECHNOLOGIES, INC.

                   (a) Landlord agrees to furnish or perform those items of
construction and those improvements (the "INITIAL IMPROVEMENTS") specified
below:

PHASE I:       i.   12,000 sf of Standard Landlord office build-out
                    (includes bathrooms,
                    locker rooms, and break room)

              ii.   49,500 sf of Production Area (drop ceiling, HVAC)

              iii.  2,500 sf of Warehouse Area

              iv.   Installation of a 750 KVA electrical transformer and
                    switchgear

              v.    Provide 500 KVA rights.]

              vi.   Provide 30 f.c. of lighting in warehouse with 400 watt
                    metal halide fixtures.

              vii.  Provide 70 f.c. of lighting in production area.

              viii. Install Fire Protection System.

              ix.   HVAC space to be air conditioned at a rate
                    of 3 tons/1000 sf

PHASE II:                  To be determined

          Landlord shall pay for the Initial Improvements up to a maximum amount
of $416,000, which such amount shall be applied toward the Initial Improvements
relative to Phase I construction, and Tenant shall pay for the cost of any and
all of the Initial Improvements (Phase I and/or Phase II) in excess of such
amount. If the cost of the Initial Improvements is estimated to exceed such
amount, such estimated overage shall be paid by Tenant before Landlord begins
construction and a final adjusting payment based upon the actual costs of the
Initial Improvements shall be made when the Initial Improvements are complete.
Landlord may collect a construction management fee, payable by Tenant within 30
days following receipt of Landlord's invoice from time to time throughout the
period of construction of the Initial Improvements, which such fee shall be
calculated based upon the scope of work of the Initial Improvements as described
herein, taking into account costs generally payable for similar services within
the market area in which the Project is located. All parties hereby acknowledge
that such construction management fee shall not be included as part of the
allowance for the Initial Improvements as set forth herein.

                  (b) If Tenant shall desire any changes, Tenant shall so advise
Landlord in writing and Landlord shall determine whether such changes can be
made in a reasonable and feasible manner. Any and all costs of reviewing any
requested changes, and any and all costs of making any changes to the Initial
Improvements which Tenant may request and which Landlord may agree to shall be
at Tenant's sole cost and expense and shall be paid to Landlord upon demand and
before execution of the change order.

                                      -23-
<PAGE>

                  (c) Landlord shall proceed with and complete the construction
of the Initial Improvements in accordance with the construction schedule
attached hereto as Exhibit C so long as Tenant executes this Lease no later than
March 16, 2004; provided, however, in the event that the Initial Improvements
are Substantially Completed by November 5, 2004, Tenant shall pay to Landlord an
amount equal to $150,000 within 30 days following the date of Substantial
Completion of the Initial Improvements. As soon as such improvements have been
Substantially Completed, Landlord shall notify Tenant in writing of the date
that the Initial Improvements were Substantially Completed. The Initial
Improvements shall be deemed substantially completed ("SUBSTANTIALLY COMPLETED")
when, in the opinion of the construction manager (whether an employee or agent
of Landlord or a third party construction manager) ("CONSTRUCTION MANAGER"), the
Premises are substantially completed except for punch list items which do not
prevent in any material way the use of the Premises for the purposes for which
they were intended. In the event Tenant, its employees, agents, or contractors
cause construction of such improvements to be delayed, the date of Substantial
Completion shall be deemed to be the date that, in the opinion of the
Construction Manager, Substantial Completion would have occurred if such delays
had not taken place. Without limiting the foregoing, Tenant shall be solely
responsible for delays caused by Tenant's request for any changes in the plans,
Tenant's request for long lead items or Tenant's interference with the
construction of the Initial Improvements, and such delays shall not cause a
deferral of the Commencement Date beyond what it otherwise would have been.
After the Initial Improvements are Substantially Completed, Tenant shall, upon
demand, execute and deliver to Landlord a letter of acceptance of delivery of
the Premises. In the event of any dispute as to the Initial Improvements,
including the Commencement Date, the certificate of the Construction Manager
shall be conclusive absent manifest error.

                  (d) The failure of Tenant to take possession of or to occupy
the Premises shall not serve to relieve Tenant of obligations arising on the
Commencement Date or delay the payment of rent by Tenant. Subject to applicable
ordinances and building codes governing Tenant's right to occupy or perform in
the Premises, Tenant shall be allowed to install its tenant improvements,
machinery, equipment, fixtures, or other property on the Premises during the
final stages of completion of construction provided that Tenant does not thereby
interfere with the completion of construction or cause any labor dispute as a
result of such installations, and provided further that Tenant does hereby agree
to indemnify, defend, and hold Landlord harmless from any loss or damage to such
property, and all liability, loss, or damage arising from any injury to the
Project or the property of Landlord, its contractors, subcontractors, or
materialmen, and any death or personal injury to any person or persons arising
out of such installations, unless any such loss, damage, liability, death, or
personal injury was caused by Landlord's negligence. Any such occupancy or
performance in the Premises shall be in accordance with the provisions governing
Tenant-Made Alterations and Trade Fixtures in the Lease, and shall be subject to
Tenant providing to Landlord satisfactory evidence of insurance for personal
injury and property damage related to such installations and satisfactory
payment arrangements with respect to installations permitted hereunder. Delay in
putting Tenant in possession of the Premises shall not serve to extend the term
of this Lease or to make Landlord liable for any damages arising therefrom.

                  (e) Except for incomplete punch list items, Tenant upon
Substantial Completion of the Initial Improvements shall have and hold the
Premises as the same shall then be without any liability or obligation on the
part of Landlord for making any further alterations or improvements of any kind
in or about the Premises.

                            HVAC MAINTENANCE CONTRACT

                  ATTACHED TO AND A PART OF THE LEASE AGREEMENT
                          DATED APRIL 22, 2004, BETWEEN

                                       and

                      WILSON GREATBATCH TECHNOLOGIES, INC.

         Paragraph 11, captioned "TENANT REPAIRS," is revised to include the
following:

         Tenant agrees to enter into and maintain through the term of the Lease,
a regularly scheduled preventative maintenance/service contract for servicing
all hot water, heating and air conditioning systems and equipment within the
Premises. The Landlord requires a qualified HVAC contractor perform this work.

       The service contract must become effective within thirty (30) days of
occupancy, and a copy of the Service Contract must be provided to Landlord
during the same period of time. Service visits should be performed on a
quarterly basis. The HVAC contractor that is used to service the equipment is
required to provide a faxed copy of all work performed to the Landlord within a
24-hour period after work is completed. If the service provider cannot provide
the Landlord with faxed copies within 24 hours, then Tenant will be required to
contract with a service provider who can meet the requirement. We suggest that
you send the following list to a qualified HVAC contractor to be assured that
these items are included in the maintenance contract:

         1.       Adjust belt tension;
         2.       Lubricate all moving parts, as necessary;
         3.       Inspect and adjust all temperature and safety controls;
         4.       Check refrigeration system for leaks and operation;
         5.       Check refrigeration system for moisture;
         6.       Inspect compressor oil level and crank case heaters;
         7.       Check head pressure, suction pressure and oil pressure;

                      WILSON GREATBATCH TECHNOLOGIES, INC.

         Per Paragraph 21, Tenant is obligated to check and address prior to
move-out of the Premises the following items. Landlord expects to receive the
Premises in a well maintained condition, with normal wear and tear of certain
areas acceptable. The following list is designed to assist Tenant in the
move-out procedures but is not intended to be all inclusive.

1.       All lighting is to be placed into good working order both prior and
         subsequent to tenants occupancy. This includes replacement of bulbs,
         ballasts, and lenses as needed.

2.       All truck doors and dock levelers should be serviced and placed in good
         operating order. This would include the necessary replacement of any
         dented truck door panels and adjustment of door tension to insure
         proper operation. All door panels which are replaced need to be painted
         to match the Building standard.

3.       All structural steel columns in the warehouse and office should be
         inspected for damage. Repairs of this nature should be pre-approved by
         the Landlord prior to implementation.

4.       Heating/air-conditioning systems should be placed in good working
         order, including the necessary replacement of any parts to return the
         unit to a well maintained condition. This includes warehouse heaters
         and exhaust fans. Upon move-out, Landlord will have an exit inspection
         performed by a certified mechanical contractor to determine the
         condition.

5.       All holes in the sheet rock walls should be repaired prior to move-out.

6.       The carpets and vinyl tiles should be in a clean condition and should
         not have any holes or chips in them. Landlord will accept normal wear
         on these items provided they appear to be in a maintained condition.

7.       Facilities should be returned in a clean condition which would include
         cleaning of the coffee bar, restroom areas, windows, and other portions
         of the space.

8.       The warehouse should be in broom clean condition with all inventory and
         racking removed. There should be no protrusion of anchors from the
         warehouse floor and all holes should be appropriately patched. If
         machinery/equipment is removed, the electrical lines should be properly
         terminated at the nearest junction box.

9.       All exterior windows with cracks or breakage should be replaced.

10.      The Tenant shall provide keys for all locks on the Premises, including
         front doors, rear doors, and interior doors.

11.      Items that have been added by the Tenant and affixed to the Building
         will remain the property of Landlord, unless agreed otherwise. This
         would include but is not limited to mini-blinds, air conditioners,
         electrical, water heaters, cabinets, flooring, etc. Please note that if
         modifications have been made to the space, such as the addition of
         office areas, Landlord retains the right to have the Tenant remove
         these at Tenant's expense.

                                      -27-

12.      All electrical systems should be left in a safe condition that conforms
         to code. Bare wires and dangerous installations should be corrected
         prior to move-out.

13.      All plumbing fixtures should be in good working order, including the
         water heater. Faucets and toilets should not leak.

                  ATTACHED TO AND A PART OF THE LEASE AGREEMENT
                          DATED APRIL 22, 2004, BETWEEN

                         TIJUANA MEXICO INVESTMENT I LLC

                                       and

                      WILSON GREATBATCH TECHNOLOGIES, INC.

     (a) Provided that as of the time of the giving of the First Extension
Notice and the Commencement Date of the First Extension Term, (x) Tenant is the
Tenant originally named herein, (y) Tenant actually occupies all of the Premises
initially demised under this Lease and any space added to the Premises, and (z)
no Event of Default exists or would exist but for the passage of time or the
giving of notice, or both; then Tenant shall have the right to extend the Lease
Term for an additional term of 5 years (such additional term is hereinafter
called the "FIRST EXTENSION TERM") commencing on the day following the
expiration of the Lease Term (hereinafter referred to as the "COMMENCEMENT DATE
OF THE FIRST EXTENSION TERM"). Tenant shall give Landlord notice (hereinafter
called the "FIRST EXTENSION NOTICE") of its election to extend the term of the
Lease Term at least 6 months, but not more than 10 months, prior to the
scheduled expiration date of the Lease Term.

     (b) Provided that as of the time of the giving of the Second Extension
Notice and the Commencement Date of the Second Extension Term, (x) Tenant is the
Tenant originally named herein, (y) Tenant actually occupies all of the Premises
initially demised under this Lease and any space added to the Premises, and (z)
no Event of Default exists or would exist but for the passage of time or the
giving of notice, or both and provided Tenant has exercised its option for the
First Extension Term; then Tenant shall have the right to extend the Lease Term
for an additional term of 5 years (such additional term is hereinafter called
the "SECOND EXTENSION TERM") commencing on the day following the expiration of
the First Extension Term (hereinafter referred to as the "COMMENCEMENT DATE OF
THE SECOND EXTENSION TERM"). Tenant shall give Landlord notice (hereinafter
called the "SECOND EXTENSION NOTICE") of its election to extend the term of the
Lease Term at least 6 months, but not more than 10 months, prior to the
scheduled expiration date of the First Extension Term.

     (c) The Base Rent payable by Tenant to Landlord during the First Extension
Term shall be the greater of (i) the Base Rent applicable to the last year of
the initial Lease term and (ii) the then prevailing market rate for comparable
space in the Project and comparable buildings in the vicinity of the Project,
taking into account the size of the Lease, the length of the renewal term,
market escalations and the credit of Tenant. The Base Rent shall not be reduced
by reason of any costs or expenses saved by Landlord by reason of Landlord's not
having to find a new tenant for such premises (including, without limitation,
brokerage commissions, costs of improvements, rent concessions or lost rental
income during any vacancy period). In the event Landlord and Tenant fail to
reach an agreement on such rental rate and execute the Amendment (defined below)
at least 4 months prior to the expiration of the Lease, then Tenant's exercise
of the renewal option shall be deemed withdrawn and the Lease shall terminate on
its original expiration date.

     (d) The Base Rent payable by Tenant to Landlord during the Second Extension
Term shall be the greater of (i) the Base Rent applicable to the last year of
the First Extension Term and (ii) the then prevailing market rate for comparable
space in the Project and comparable buildings in the vicinity of the Project,
taking into account the size of the Lease, the length of the renewal term and
the credit of Tenant. The Base Rent shall not be reduced by reason of any costs
or expenses saved by Landlord by reason of Landlord's not having to find a new
tenant for such premises (including, without limitation, brokerage commissions,
costs of improvements, rent concessions or lost rental income during any vacancy
period). In the event Landlord and Tenant fail to reach an agreement on such
rental rate and execute the Amendment (defined below) at least 4 months prior to
the expiration of the Lease, then Tenant's exercise of the renewal option shall
be deemed withdrawn and the Lease shall terminate at the end of the First
Extension Term.

                                      -29-

     (e) The determination of Base Rent does not reduce the Tenant's obligation
to pay or reimburse Landlord for operating expenses and other reimbursable items
as set forth in the Lease, and Tenant shall reimburse and pay Landlord as set
forth in the Lease with respect to such Operating Expenses and other items with
respect to the Premises during the First Extension Term and Second Extension
Term without regard to any cap on such expenses set forth in the Lease.

     (f) Except for the Base Rent as determined above, Tenant's occupancy of the
Premises during the First Extension Term and the Second Extension Term shall be
on the same terms and conditions as are in effect immediately prior to the
expiration of the initial Lease Term or the First Extension Term; provided,
however, Tenant shall have no further right to any allowances, credits or
abatements or any options to expand, contract, renew or extend the Lease.

     (g) If Tenant does not give the First Extension Notice within the period
set forth in paragraph (a) above, Tenant's right to extend the Lease Term for
the First Extension Term and the Second Extension Term shall automatically
terminate. If Tenant does not give the Second Extension Notice within the period
set forth in paragraph (b) above, Tenant's right to extend the Lease Term for
the Second Extension Term shall automatically terminate. Time is of the essence
as to the giving of the First Extension Notice and Second Extension Notice.

     (h) Landlord shall have no obligation to refurbish or otherwise improve the
Premises for the First Extension Term or the Second Extension Term. The Premises
shall be tendered on the Commencement Date of the First Extension Term and
Second Extension Term in "as-is" condition.

     (i) If the Lease is extended for either the First Extension Term or Second
Extension Term, then Landlord shall prepare and Tenant shall execute an
amendment to the Lease confirming the extension of the Lease Term and the other
provisions applicable thereto (the "Amendment").

     (j) If Tenant exercises its right to extend the term of the Lease for the
First Extension Term or Second Extension Term pursuant to this Addendum, the
term "Lease Term" as used in the Lease, shall be construed to include, when
practicable, the First Extension Term or Second Extension Term, as applicable,
except as provided in (f) above.

                      WILSON GREATBATCH TECHNOLOGIES, INC.

         (a) "OFFERED SPACE" shall mean Tijuana Industrial Center #10,
consisting of approximately 40,000 s.f. as more fully described on the
attachment Exhibit B.

         (b) Provided that as of the date of the giving of Landlord's Notice,
(x) Tenant is the Tenant originally named herein, (y) Tenant actually occupies
all of the Premises originally demised under this Lease and any premises added
to the Premises, and (z) no Event of Default or event which but for the passage
of time in the giving of notice, or both, would constitute an Event of Default
has occurred and is continuing, if at any time during the Lease Term any lease
for any portion of the Offered Space shall expire, then Landlord, before
offering such Offered Space to anyone, other than the tenant then occupying such
space (or its affiliates), shall offer to Tenant the right to include the
Offered Space within the Premises on the same terms and conditions upon which
Landlord intends to offer the Offered Space for lease.

         (c) Such offer shall be made by Landlord to Tenant in a written notice
(hereinafter called the "FIRST OFFER NOTICE") which offer shall designate the
space being offered and shall specify the terms which Landlord intends to offer
with respect to any such Offered Space. Tenant may accept the offer set forth in
the First Offer Notice by delivering to Landlord an unconditional acceptance
(hereinafter called "TENANT'S NOTICE") of such offer within 5 business days
after delivery by Landlord of the First Offer Notice to Tenant. Time shall be of
the essence with respect to the giving of Tenant's Notice. If Tenant does not
accept (or fails to timely accept) an offer made by Landlord pursuant to the
provisions of this Addendum with respect to the Offered Space designated in the
First Offer Notice, Landlord shall be under no further obligation with respect
to such space by reason of this Addendum.

         (d) Tenant must accept all Offered Space offered by Landlord at any one
time if it desires to accept any of such Offered Space and may not exercise its
right with respect to only part of such space. In addition, if Landlord desires
to lease more than just the Offered Space to one tenant, Landlord may offer to
Tenant pursuant to the terms hereof all such space which Landlord desires to
lease, and Tenant must exercise its rights hereunder with respect to all such
space and may not insist on receiving an offer for just the Offered Space.

         (e) If Tenant at any time declines any Offered Space offered by
Landlord, Tenant shall be deemed to have irrevocably waived all further rights
under this Addendum, and Landlord shall be free to lease the Offered Space to
third parties including on terms which may be less favorable to Landlord than
those offered to Tenant.
