     That the Parties hereto do hereby mutually agree as follows:

     1.   Premises; Condition and Expansion of Premises.

     A.   Tenant hereby leases from Landlord those certain premises (hereinafter
referred to as the "Premises") depicted by cross-hatching on the diagram
attached hereto as EXHIBIT A. As used in this Lease, the "Building" shall mean
that certain building located at 1401 Sheridan Road, North Chicago, Illinois
60064, commonly known as the M3 Building, and including the use in common with
the Landlord of the Building, the common areas and parking areas serving the
Building. Landlord shall install firewalls to separate the private networks of
the Landlord and Tenant. These separation firewalls shall be deployed at both
the Landlord's and Tenant's networks on either end of the Inter-Company Link and
Gigabit connection. Other than Landlord's installation of the firewalls, Tenant
acknowledges that it is leasing the Premises "as is" without any representation
or warranty.

     B.   Tenant shall have the right to reduce the size of the Premises at any
time during the Term upon not less than ninety (90) days written notice to
Landlord, at which time Base Rent (as described in PARAGRAPH 3 below) shall be
proportionately reduced. Each reduction of the Premises shall comprise a minimum
of 2,000 square feet of space contiguous to Abbott useable space.

     C.   Upon the written agreement of the Parties, Tenant shall be permitted
to add space within the Building or adjacent to the Building on the same general
terms and conditions of this Lease.

     2.   LEASE TERM. The term (the "Term") of this Lease shall commence on the
Effective Date and shall end on __________, 200_ (the "Termination Date").
Notwithstanding

<Page>

the foregoing, Tenant shall have the right to terminate this Lease at any time
upon not less than 180 days written notice to Landlord.

     3.   BASE RENT. Tenant agrees to pay as annual base rent ("Base Rent")
Landlord's fully burdened cost per square foot of the Premises for each year
("Lease Year") during the Term payable in equal monthly installments ("Monthly
Base Rent"). Monthly Base Rent for each Lease Year is set forth in the Schedule
attached hereto as EXHIBIT A-1. The obligation to pay Rent (defined below) shall
commence on the Effective Date. The first Lease Year shall commence on the
Effective Date and end on December 31, 2004, and each succeeding Lease Year
shall commence on January 1 of the following calendar year. The final Lease Year
shall commence on January 1, 2014 and end on ___________ __, 2014. Rent shall be
paid to Landlord in advance on or before the first day of each month of the
Term, and shall be payable to Landlord at the address shown in the Schedule, or
at such other place as Landlord may direct from time to time in writing. If the
Term shall commence on a day other than the first day of a calendar month,
Tenant shall pay a prorated monthly Rent for such initial partial month.
Payments not made when due shall bear interest at a rate per annum equal to the
rate which Citibank N.A. (or its successor or another major money center
commercial bank agreed to by the Parties) announces as its prime lending rate,
as in effect from time to time plus two percent (2%).

     All Base Rent and the cost of any Additional Services or Extra Services
provided pursuant to PARAGRAPHS 6 and 7 hereof, together with any other sum
required to be paid by Tenant pursuant to this Lease (such sums are collectively
referred to herein as "Rent") shall be paid when due, without demand, deduction,
offset or discount and all in lawful money of the United States. The payment of
Rent hereunder is independent of each and every other covenant and agreement
contained in this Lease.

     4.   USE OF PREMISES. The Premises shall be occupied and used only for
office, laboratory and manufacturing purposes and for no other purpose. Without
limiting the generality of the foregoing, no use shall be made of the Premises
nor acts done which will increase the existing rate of insurance upon the
Building or cause a cancellation of any insurance policy covering the Building
or any part thereof. Tenant shall not commit, or suffer to be committed, any
waste upon the Premises, or any public or private nuisance, or other act or
thing which may disturb the quiet enjoyment of any other tenant in the Building,
nor, without limiting the generality of the foregoing, shall Tenant allow the
Premises to be used for any improper, immoral, unlawful or objectionable
purpose.

     Tenant agrees that Tenant, together with any other Person (as defined
below) entering the Premises with Tenant's permission, will comply with (i) all
federal, state and municipal laws, ordinances and regulations applicable to
Tenant's use and occupancy of the Premises, (ii) all covenants, conditions and
restrictions of record applicable to Tenant's use and occupancy of the Premises,
and (iii) the rules and regulations attached hereto as EXHIBIT C together with
all other reasonable rules and regulations which Landlord may reasonably make
from time to time for the management, safety, care and cleanliness of the
Building, consistent with the same rules and regulations which Landlord
implements for its other buildings with analogous uses. The violation of any
such items shall be deemed a material breach of this Lease by Tenant. "PERSON"

<Page>

means an individual, a general or limited partnership, a corporation, a trust, a
joint venture, an unincorporated organization, a limited liability entity, any
other entity and any Governmental Authority.

     5.   PRIVILEGES OF HOSPIRA EMPLOYEES. Tenant, its employees and invitees,
may use in common with Landlord, its employees and invitees the conference rooms
located in the Building, the cafeteria serving the Building and the exercise
facilities serving the Building. Tenant's use of conference rooms shall be in
accordance with Landlord's reservation procedures. Tenant's use of exercise
facilities and the cafeteria shall be in accordance with the rules and
procedures applicable to Landlord's employees.

     6.   UTILITIES AND OTHER SERVICES FURNISHED BY LANDLORD. On a twenty-four
(24) hour and seven (7) days per week basis, Landlord shall furnish to Tenant
during the Term: (i) automatic passenger elevator service; (ii) restroom
facilities with hot and cold water; (iii) heating and air conditioning, as
appropriate (excluding Tenant process areas); (iv) emergency lighting,
electricity for lighting, computers, telecommunications equipment but excluding
any electricity used in providing the Additional Services (as defined below) or
the Extra Services (as defined below); and (v) cold water as required for
existing plumbing for the Premises.

     Consistent with Landlord's current practice with respect to Landlord's own
buildings which are analogous to the Building, Landlord shall furnish to Tenant
the services described in EXHIBIT B-1 which may be changed from time to time in
Landlord's reasonable discretion upon thirty (30) days advance written notice to
Tenant. Upon written request and reasonable written notice, Landlord shall
furnish janitorial, cleaning and security services during weekend hours at rates
determined in accordance with EXHIBIT B-5 attached hereto. During normal
business hours and upon written request and reasonable prior notice, Landlord
shall furnish freight elevator service to Tenant.

     Landlord may, but shall have no obligation to, provide, at Tenant's
request, any other Additional Services as it is reasonably possible for Landlord
to provide within a reasonable period after the time such additional service is
requested (each, an "Additional Service") including, but not limited to, the
services described in EXHIBIT B-2 attached hereto.

     To the extent Landlord incurs any additional cost or expense as a result of
Landlord providing Additional Services at Tenant's request, Tenant shall
reimburse Landlord for such cost or expense, such amount to be considered
additional Rent hereunder. All charges for such Additional Services shall be due
and payable at the same time as the installment of Monthly Base Rent with which
they are billed, or if billed separately, shall be due and payable within thirty
(30) days after Tenant receives Landlord's bill therefor. Any such billings for
Additional Services shall include an itemization of the Additional Services
rendered and the charge for each such service, which charge shall be calculated
as Landlord's fully burdened cost to perform such services, determined in
accordance with EXHIBIT B-5. The Additional Services shall be performed by
Landlord in the same manner Landlord performs such services for itself.

     If the Tenant fails to promptly pay charges for Additional Services,
Landlord, upon not less than ten (10) days' notice, may, in addition to any
other remedies available to Landlord,

<Page>

discontinue furnishing Additional Services until such time as Tenant has made
payment therefor. Such discontinuance shall not be deemed an eviction or
disturbance of Tenant's use of the Premises, shall not render Landlord liable
for damages, nor shall it relieve Tenant from performance of Tenant's
obligations under this Lease.

     Landlord shall not be liable for any loss or damage caused by or resulting
from any variation, interruption or failure of any utilities and services to be
provided by Landlord hereunder due to any cause whatsoever, other than
Landlord's negligence or willful misconduct, and no temporary interruption or
failure of such utilities and services incident to the making of repairs,
alterations or improvements, or due to accident, strike or conditions or events
beyond Landlord's reasonable control shall be deemed an eviction of Tenant or
relieve Tenant from any of Tenant's obligations hereunder, including, without
limitation, the payment of Rent.

     7.   EXTRA SERVICES.

     A.   LANDLORD'S DELIVERY OF EXTRA SERVICES. At Tenant's expense, Landlord
shall furnish the extra services described on EXHIBITS B-3 and B-4 attached
hereto ("EXTRA SERVICES").

               1.   Landlord shall perform all Extra Services in a manner which
          is substantially similar in nature, quality and timeliness to the
          analogous services provided by Landlord prior to the Commencement
          Date.

               2.   Landlord shall perform its duties and responsibilities
          hereunder in good faith based on its past practices. Landlord shall
          not be liable or held accountable, in damages or otherwise, for any
          error of judgment or any mistake of fact or law or for anything that
          Landlord does or refrains from doing in good faith hereunder, except
          in the case of its gross negligence or willful misconduct.

               3.   Nothing in this Lease shall require Landlord to perform any
          Extra Service in a manner that would constitute a violation of
          applicable laws.

               4.   Landlord shall not be obligated to perform any Extra Service
          in a volume or quantity which exceeds the planned 2004 volumes or
          quantities of analogous services performed for the applicable
          operation of Tenant, without reference to the transactions
          contemplated by the Separation and Distribution Agreement of even date
          herewith between Landlord and Tenant (the "Separation and Distribution
          Agreement"). Tenant may request a higher volume or quantity of such
          historical volumes or quantities of an Extra Service, which request
          Landlord may accept or reject in its sole discretion. If Landlord
          agrees to such a request, the Parties shall cooperate and act in good
          faith to make any modifications to the applicable Schedule for such
          Extra Service.

               5.   (i) Landlord will not be required to perform any of the
          Extra Services for the benefit of any Person other than Tenant, and
          (ii) EXCEPT AS EXPRESSLY PROVIDED ABOVE IN THIS PARAGRAPH 7A., EACH
          PARTY ACKNOWLEDGES AND AGREES THAT ALL EXTRA SERVICES

<Page>

          AND PRODUCTS ARE PROVIDED ON AN "AS-IS" BASIS AND THAT, LANDLORD MAKES
          NO WARRANTIES, EXPRESS OR IMPLIED, WITH RESPECT TO THE EXTRA SERVICES
          AND PRODUCTS, AND HEREBY DISCLAIMS ANY REPRESENTATION OR WARRANTY OF
          MERCHANTABILITY, FITNESS FOR ANY PARTICULAR PURPOSE, NON-INFRINGEMENT
          OR ANY OTHER WARRANTY WHATSOEVER.

     B.   CHARGES FOR EXTRA SERVICES. The charges for the Extra Services (the
"Extra Service Charges") shall be determined in accordance with EXHIBIT B-5. If
the Tenant fails to timely pay Landlord's charges for Extra Services, Landlord,
upon not less than ten (10) days' notice, may, in addition to any other remedies
available to Landlord, discontinue furnishing such Extra Services until such
time as Tenant has made payment therefor. No such discontinuance shall be deemed
an eviction or disturbance of Tenant's use of the Premises or render Landlord
liable for damages or relieve Tenant from performance of Tenant's obligations
under this Lease.

     C.   CHANGES TO EXTRA SERVICES. Except as provided in PARAGRAPH 7F. below,
the Parties acknowledge that Landlord may make changes from time to time in the
manner of performing the Extra Services if Landlord is making similar changes in
performing analogous services for itself and if Landlord furnishes to Tenant
substantially the same notice (in content and timing, but in any event no less
than thirty (30) days) as Landlord shall furnish to others in its own
organization respecting such changes. No such change shall affect the Extra
Services Charges for the applicable Extra Service.

     D.   TRANSITIONAL NATURE OF EXTRA SERVICES. The Parties acknowledge the
transitional nature of the Extra Services and agree to cooperate in good faith
and to use commercially reasonable efforts to effectuate a smooth transition of
the Extra Services from Landlord to Tenant (or its designee).

     E.   COOPERATION. In the event that (i) there is nonperformance of any
Extra Service as a result of a Force Majeure (as defined in PARAGRAPH 30.F.
below), or (ii) the provision of an Extra Service would violate applicable law,
the Parties agree to work together in good faith to arrange for an alternative
means by which Tenant may obtain, at Tenant's sole cost, the Extra Service so
affected.

     F.   USE OF THIRD PARTIES TO PROVIDE THE EXTRA SERVICES. Landlord may
perform its obligations through its Subsidiaries (as defined below) or, if
Landlord is obtaining analogous services for itself from agents, subcontractors
or independent contractors, through the use of such agents, subcontractors or
independent contractors if Landlord furnishes Tenant substantially the same
notice (in content and timing) as Landlord shall furnish to its own organization
respecting such use of Third Parties. If Landlord is not obtaining analogous
services for itself from Third Parties, Landlord may perform its obligations
hereunder through the use of agents, subcontractors or independent contractors
only upon obtaining the prior written consent of Tenant. Notwithstanding the
foregoing, Landlord shall not be relieved of its obligations under this Lease by
use of such Subsidiaries, agents, subcontractors or contractors. "SUBSIDIARY" or
"Subsidiaries" means another Person or Persons directly or indirectly controlled
by such first

<Page>

Person. As used herein, "control" means the possession, directly or indirectly,
of the power to direct or cause the direction of the management and policies of
such Person(s), whether through ownership of voting securities or other
interests, by contract or otherwise.

     G.   EARLY TERMINATION OF EXTRA SERVICES. Tenant shall have the right at
any time during the Term to terminate its obligation to purchase any individual
Extra Service, upon the giving of one hundred eighty (180) days, advance written
notice to Landlord. Effective on the second anniversary of the Effective Date
and any time thereafter, Landlord shall have the right, upon one hundred eighty
180 days advance written notice to Tenant, to terminate its obligation to
provide any of the Extra Services described on EXHIBIT B-4.

     H.   INFORMATION TRANSMISSION. On or prior to the last day of the term of
an Extra Service, Landlord shall use reasonable commercial efforts to support
any transfer of Information concerning the relevant Extra Services to Tenant. If
requested by Tenant, Landlord shall deliver to Tenant, within such time periods
as the Parties may reasonably agree, all Information received or computed for
the benefit of Tenant during the term of an Extra Service, in electronic and/or
hard copy form; provided, however, that (i) Landlord shall not have any
obligation to provide Information in any non-standard format, and (ii) Landlord
shall be reimbursed for its reasonable out-of-pocket costs for providing
Information in any format other than its standard format.

     I.   MUTUAL COOPERATION. The Parties shall cooperate with each other in
connection with the performance of the Extra Services hereunder, including
producing on a timely basis all Information that is reasonably requested with
respect to the performance of Extra Services and the transition of such Extra
Services at the end of their applicable term; provided, however, that such
cooperation shall not unreasonably disrupt the normal operations of the Parties.

     J.   LIMITATIONS ON LIABILITY FOR FAILURE TO PROVIDE EXTRA SERVICES. FOR
EACH TWELVE (12) MONTH PERIOD DURING THE TERM, THE FIRST SUCH PERIOD COMMENCING
ON THE EFFECTIVE DATE AND SUBSEQUENT SUCH PERIODS COMMENCING ON EACH YEARLY
ANNIVERSARY THEREAFTER, THE MAXIMUM LIABILITY OF LANDLORD TO, AND THE SOLE
REMEDY OF, TENANT WITH RESPECT TO ANY AND ALL CLAIMS ARISING UNDER OR IN
CONNECTION WITH THE PROVISION OF EXTRA SERVICES UNDER THIS LEASE, REGARDLESS OF
THE THEORY UPON WHICH THE LIABILITY IS PREMISED, SHALL NOT EXCEED THE LANDLORD'S
PROFITS FOR PERFORMING EXTRA SERVICES HEREUNDER, WHICH SHALL BE DEEMED TO BE
EQUAL TO THE AMOUNT OF THE MARK-UP RECEIVED BY LANDLORD AS SET FORTH ON EXHIBIT
B-5 AND AS MAY BE ADJUSTED PURSUANT TO THE TERMS OF EXHIBIT-B-5. IN NO EVENT
SHALL LANDLORD, ITS SUBSIDIARIES OR THEIR RESPECTIVE DIRECTORS, OFFICERS,
EMPLOYEES OR AGENTS BE LIABLE TO THE OTHER PARTY FOR INDIRECT, EXEMPLARY,
INCIDENTAL, CONSEQUENTIAL OR PUNITIVE DAMAGES (INCLUDING LOST OR ANTICIPATED
PROFITS RELATING TO THE SAME) IN CONNECTION WITH THE PERFORMANCE OF EXTRA
SERVICES UNDER THIS LEASE, EVEN IF THEY HAVE BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES, AND TENANT HEREBY WAIVES ON BEHALF OF ITSELF AND ITS SUBSIDIARIES
ANY CLAIM FOR SUCH

<Page>

DAMAGES, INCLUDING ANY CLAIM FOR PROPERTY DAMAGE OR LOST PROFITS, WHETHER
ARISING IN CONTRACT, TORT OR OTHERWISE.

     K.   THIRD PARTY CLAIMS. Tenant shall indemnify, defend and hold harmless
Landlord, its Subsidiaries and each of their directors, officers and employees,
and each of the successors and assigns of any of the foregoing (collectively,
the "Landlord Indemnitees"), from and against any and all claims of any Person
other than Abbott, any Abbott Subsidiary, Hospira and any Hospira Subsidiary
(each herein a "Third Party") relating to, arising out of or resulting from
Landlord's furnishing or failing to furnish the Extra Services provided for in
this Lease, other than Third Party claims arising out of the gross negligence or
willful misconduct of any Landlord Indemnitee.

     L.   TITLE TO INTELLECTUAL PROPERTY. Tenant acknowledges that it will
acquire no right, title or interest (including any license rights or rights of
use) in any intellectual property which is owned or licensed by Landlord, by
reason of the provision of the Extra Services provided hereunder. Tenant will
not remove or alter any copyright, trademark, confidentiality or other
proprietary notices that appear on any intellectual property owned or licensed
by Landlord, and shall reproduce any such notices on any and all copies thereof.
Tenant will not attempt to decompile, translate, reverse engineer or make
excessive copies of any intellectual property owned or licensed by Landlord, and
shall promptly notify Landlord or any such attempt, regardless of whether by
Tenant or any Third Party, of which Tenant becomes aware.

     8.   ALTERATIONS AND REPAIRS. Tenant shall not make a structural change or
changes which can be seen from the exterior of the Building without Landlord's
prior written consent. For purposes of this Lease, hot work, work requiring core
drilling and surface penetration and work involving pressurized lines shall
automatically be deemed a structural change requiring Landlord's prior written
consent. Tenant shall not do any painting or decorating, erect any non-moveable
partitions or make any additions, improvements, alterations or repairs to the
Premises costing in each case more than $50,000.00 without Landlord's prior
written consent, which consent shall not be unreasonably withheld or delayed. In
the event Tenant proposes to make any addition, improvement, alteration or
repair requiring Landlord's prior written approval, Tenant shall, prior to
commencing any such activity, submit to Landlord for its prior written approval:
(i) detailed plans and specifications; (ii) all necessary governmental permits
evidencing compliance with all applicable governmental rules, regulations and
requirements; (iii) certificates of insurance in form and amounts reasonably
required by Landlord, naming Landlord and any other Parties designated by
Landlord as additional insureds; and (iv) all other documents and information as
Landlord may reasonably request in connection with such work. Neither approval
of the plans and specifications nor supervision of the addition, improvement or
alteration by Landlord shall constitute a representation or warranty by Landlord
as to the accuracy, adequacy, sufficiency or propriety of such plans and
specifications or as to the quality of workmanship or the compliance of such
alteration with applicable law. Tenant shall pay the entire cost of the
addition, improvement or alteration. Each addition, improvement, alteration and
repair shall be performed in a good and workmanlike manner, in accordance with
the plans and specifications approved by Landlord, and shall meet or exceed the
standards for construction and quality of materials established by Landlord for
the Building. In addition, each addition,

<Page>

improvement, alteration and repair shall be performed in compliance with all
applicable governmental laws, ordinances, codes, orders, rules and regulations.
Each addition, improvement, alteration and repair shall be performed by
contractors approved by Landlord and all contractors shall act in harmony with
Landlord's employees and contractors.

     Tenant agrees to protect, defend and indemnify the Landlord Indemnitees,
the Premises and the Building from and against any and all liabilities of every
kind and description which may arise out of or be connected in any way with said
additions, alterations, improvements or repairs or the like, whether performed
by or under the direction of Tenant and at the cost of Tenant. Upon completion
of any addition, improvement, alteration or repair, if Landlord requests, Tenant
shall promptly furnish Landlord with sworn owner's and contractors' statements
and full and final waivers of lien covering all labor and materials included in
such work. Tenant shall not permit any mechanic's lien to be filed against the
Building, or any part thereof, arising out of any alteration performed, or
alleged to have been performed, by or on behalf of Tenant. If any such lien is
filed, Tenant shall within thirty (30) days thereafter have such lien released
of record or deliver to Landlord a bond in form, amount, and issued by a surety
satisfactory to Landlord, indemnifying Landlord against all costs and
liabilities resulting from such lien and the foreclosure or attempted
foreclosure thereof. If Tenant fails to have such lien so released or to deliver
such bond to Landlord, Landlord, without investigating the validity of such
lien, may pay or discharge the same; and Tenant shall reimburse Landlord upon
demand for the amount so paid by Landlord, including Landlord's reasonable
expenses and attorneys' fees.

     Unless otherwise provided in this Paragraph or by written agreement, all
additions, improvements, alterations, repairs and fixtures (except Tenant's
furniture, trade fixtures and equipment) installed by Tenant during the Term
shall be surrendered with the Premises and shall become Landlord's property
without compensation to Tenant. Landlord shall have the option at the time of
granting consent to additions, improvements and alterations to require their
removal and the restoration of the Premises to the condition existing
immediately prior to their installation at the expiration or early termination
of the Lease. For any such installations which do not require Landlord's
consent, Landlord shall have the option of requiring their removal and the
restoration of the Premises to the condition existing immediately prior to their
installation at the expiration or early termination of the Lease.

     Tenant shall remove its furniture, trade fixtures and equipment and all
other items of personal property from the Premises prior to the end of the Term
or any extension thereof, or at the termination of right of possession, however
ended. Tenant shall repair any damages caused by the removal of such items. If
Tenant does not remove such items, Tenant shall be conclusively presumed to have
conveyed the same to Landlord under this Lease as a bill of sale without further
payment or credit by Landlord to Tenant, or at Landlord's sole option, Landlord
may cause the items covered in this Paragraph to be removed and stored at the
risk and cost of Tenant. Tenant shall pay to Landlord, upon demand, any and all
reasonable expenses incurred in such removal and all reasonable storage charges
against such property so long as the same shall be in Landlord's possession or
under Landlord's control. Any such property of Tenant not removed from the
Premises or retaken from storage by Tenant within thirty (30) days after the

<Page>

end of the Term, however terminated or any extension thereof, at Landlord's sole
option, shall be conclusively deemed to have been forever abandoned by Tenant.

     9.   MAINTENANCE AND REPAIR.

     A.   Landlord shall at its own expense, maintain and keep in good repair
and in a manner consistent with the maintenance and standards of other similar
buildings owned by Landlord the foundation, walls (load bearing and wall
surfaces in common corridors), exterior doors and doors through load bearing
walls, floors, flooring (building standard carpet and tile), ceilings (excluding
false ceilings not located in common areas), roof, elevators and other
structural portions of the Building and common areas, and shall maintain the
fire mains and sprinkler system in the Building and the Building's mechanical,
electrical, plumbing, heating and ventilating equipment and systems. Landlord
shall, also, at its sole cost and expense, maintain the following
infrastructures serving the Premises:

     Distribution piping up to the first isolation valve upstream of any Tenant
process for fresh water and steam plant;

     Distribution piping downstream of the utilities backflow preventer for
Nitrogen, Carbon Dioxide, Compressed Air and Plant Air;

     Distribution piping downstream of the utilities isolation valve for
distilled water and lake water;

     WFI stills, tanks and recirculation loop;

     ACW water line up to the inlet of the ACW's back flow preventer;

     Condensate distribution piping downstream of first isolation valve from the
first trap;

     Power Distribution up to MCC panels; and

     Nine (9) break tanks located within the basement of the Premises and all
associated piping discharging from the break tanks only.

     Landlord shall perform its maintenance in a manner designed to minimize
interference with Tenant's use of the Premises to the extent such is reasonably
possible without incurring additional costs. Landlord shall perform its
maintenance obligations in accordance with the laws of the United States, the
State of Illinois and all directions and regulations of governmental agencies
having jurisdiction over the Premises. Landlord shall have no obligation for
Tenant's personal property, furniture, trade fixtures and equipment, which shall
be Tenant's responsibility.

     B.   Tenant shall at its own expense, maintain and keep in good repair and
in a manner consistent with the current standards of the Building, the process
HVAC systems and controls, the flooring (excluding building standard carpet and
tile); false ceilings, interior doors, non-load

<Page>

bearing walls within the Premises. Tenant shall also, at its sole cost and
expense maintain the following components of system infrastructure list:

     Above grade chemical sewer piping; storm sewer other than below grade
piping and grade roof drains piping;

     Power Distribution from the MCC panels and beyond;

     Nitrogen, carbon dioxide and distilled water systems up to the inlet
isolation valve to the secondary backflow preventer or up to the first isolation
valve upstream of any process takeoff;

     WFI inlet control valve to the break tank and beyond; and

     ACW system from the backflow preventer and beyond.

     C.   Tenant shall, at its expense, maintain its furniture, trade fixtures
and equipment, at all times in good condition and repair. Tenant shall be
responsible for the cleaning and maintenance of all Tenant's furniture, trade
fixtures and equipment. Tenant shall commit no waste of any kind on or about the
Premises and Tenant shall pay for all damage to the Building, as well as damage
to tenants or occupants thereof, caused by misuse or neglect of the Premises, by
Tenant or Tenant's employees, agents or invitees. At the expiration of the Term,
Tenant shall surrender the Premises in good condition, normal wear and tear and
damage by fire or other insured casualty excepted.

     10.  ASSIGNMENT-SUBLEASE. This Agreement shall be binding upon
and inure to the benefit of the Parties hereto and their respective successors
and permitted assigns; PROVIDED, HOWEVER, that neither Party may assign its
rights or delegate its obligations under this Agreement without the express
prior written consent of the other Party hereto. Notwithstanding the
foregoing, this Agreement shall be assignable by either Party in whole with
the prior written consent of the other Party (which consent shall not be
unreasonably withheld, delayed or conditioned) in connection with: (i) a
merger or consolidation of such Party; (ii) the sale of all or substantially
all of the assets of such Party; or (iii) the acquisition by a Third Party of
at least 30% of the combined voting power of the then-outstanding securities
of such Party entitled to vote generally in the election of directors (each
such occurrence, a "Change of Control Event"), in each case so long as the
resulting, surviving or transferee Person assumes all the obligations of the
assignor hereunder by operation of law or pursuant to an agreement in form and
substance reasonably satisfactory to the other Party. It shall not be deemed
to be unreasonable for a Party to withhold consent to assignment in connection
with a Change of Control Event on the basis that the proposed assignee is a
competitor of such Party. In the event a Party effects a Change of Control
Event without the other Party's prior written consent to assign this Agreement
as set forth above, the latter Party may terminate this Agreement, in its sole
discretion, with effect immediately upon the occurrence of such Change of
Control Event.

     11.  INDEMNIFICATION AND INSURANCE. Landlord shall not be liable to Tenant
or to any other Persons for any injury to or death of any Person or for loss or
damage to property (including property of Tenant) occurring in the Building or
the Premises from any cause whatsoever, except to the extent caused by
Landlord's negligence or willful misconduct. Tenant agrees to indemnify and save
Landlord harmless from all loss, damage, liability and expense

<Page>

(including expense of defending claims) relating to any actual or alleged injury
to or death of any Person or loss or damage to property caused by or resulting
from any occurrence on the Premises, except to the extent caused by Landlord's
negligence or willful misconduct. Tenant shall, at Tenant's expense, maintain
liability insurance and "All Risk" insurance with insurers, coverages, amounts
and waiver of subrogation and cancellation clauses acceptable to Landlord. The
liability insurance coverage shall include, without limitation, minimum limits
of $2,000,000.00 (combined single limit per occurrence and $10,000,000.00 annual
aggregate) for property damage. For bodily injuries and death, Tenant's
insurance carrier should be licensed to do business in Illinois and maintain a
minimum Best's rating of "A", category "X". Tenant's "All Risk" insurance
coverage shall include coverage of its moveable fixtures, office equipment,
furniture, trade fixtures and all other items of Tenant's property on the
Premises. Such policy or policies shall name Landlord as an additional insured
and shall be noncancellable as to Landlord and not subject to material change
except upon at least thirty (30) days' prior written notice given to Landlord.
Tenant shall furnish Landlord with a copy of said policy or policies or other
acceptable evidence that said insurance is in effect on the date hereof and at
least fifteen (15) days prior to the expiration of the then current policies.
Landlord shall maintain commercial general liability insurance and "All Risk"
insurance for the full replacement value of the Building and all improvements,
machinery and fixtures. Each Party may self-insure its insurance obligations
hereunder.

     12.  INSPECTION. Landlord may retain a key to the Premises and Landlord and
its employees and agents shall have the right to inspect the Premises at all
reasonable times and to enter the same whenever reasonably necessary to exercise
any right or privilege of Landlord under this Lease.

     13.  EMINENT DOMAIN. If the entire Premises (or a material portion thereof
such that the remainder of the Premises is no longer suitable for Tenant's use)
shall be taken by any public or governmental authority under the power of
eminent domain, the Term shall cease as of the date possession is taken by such
authority and the Rent shall be paid up to that date. If only a part of the
Premises shall be taken and the remainder remains tenantable for the purposes
for which Tenant has been using the Premises, then this Lease shall continue in
effect, except that the Rent shall be reduced in proportion to the amount of
square footage of the Premises so taken, and Landlord, at its expense, shall
make all necessary repairs and alterations to the Premises required by such
taking. However, Landlord shall not be required to make such repairs and
alterations, and this Lease shall terminate on the date possession is taken by
the applicable authority, if so much of the Building is taken by eminent domain
so as to make such repairs and alterations, in Landlord's reasonable judgment,
economically disadvantageous. All damages awarded for such taking may be
retained by Landlord, whether such damage is awarded as compensation for
diminution in the value of the leasehold or to the fee of the Premises. Tenant
shall be entitled to make a separate claim for cost of removal of equipment and
fixtures and Landlord shall not be entitled to any separate award arising out of
such claim. The term "eminent domain" as used herein shall include the exercise
of any similar governmental power and any purchase or other acquisition in lieu
thereof.

<Page>

     14.  FIRE AND OTHER CASUALTY. Should the Building or the Premises be
damaged by fire or other casualty, and if the damage is repairable within ninety
(90) days from the date of such casualty (with the repair work and the
preparation therefor to be done during regular working hours on regular working
days), as determined by Landlord's architect, then the damage shall be repaired
with due diligence by Landlord. In the meantime, Rent shall be abated in the
same proportion that the untenantable portion of the Premises bears to the whole
thereof. Should the Premises or the Building be completely destroyed by fire or
other casualty, or should they be damaged to such an extent that the damage
cannot be repaired within ninety (90) days from the date of the casualty, as
determined by Landlord's architect, Landlord and Tenant shall each have the
option of terminating this Lease and shall so advise the other within thirty
(30) days after the date of the casualty. If neither Party has elected to
terminate this Lease within said thirty (30) day period, Landlord shall commence
and prosecute with reasonable diligence any work necessary to restore or repair
the Premises. For the period from the occurrence of any damage to the Premises
to the date of completion of the repairs (or to the date of termination of this
Lease) the Rent shall be abated in the same proportion as the untenantable
portion of the Premises bears to the whole thereof. Rent hereunder shall not
abate if Tenant's negligence was the cause of the damage or casualty.

     15.  WAIVER OF SUBROGATION. Tenant and Landlord hereby mutually release
each other from liability and waive all right of recovery against each other for
any loss from perils insured against under their respective "All Risk" insurance
policies, including any extended coverage and endorsements thereto, and agree to
cause their respective insurers to do the same.

     16.  DEFAULTS AND REMEDIES.

     A.   DEFAULTS BY TENANT. The occurrence of any of the following shall
constitute a default ("Default") by Tenant hereunder:

               1.   If Tenant  defaults in the payment of Rent, and if the
          default is not remedied within five (5) days after written notice
          thereof by Landlord to Tenant;

               2.   If Tenant defaults in the prompt and full performance of any
          term, covenant or provision of this Lease (except those specified in
          SUBPARAGRAPHS (1), (3), (4), (5), (6) and (7) of this SUBPARAGRAPH A
          of PARAGRAPH 16) and if such default is not remedied within thirty
          (30) days after notice thereof by the Landlord; provided, however, if
          such default is capable of being cured but cannot by its nature be
          cured within thirty (30) days, Tenant shall have such longer period as
          is reasonably necessary (not to exceed ninety (90) days from the date
          of the initial default) to cure such default, provided Tenant has
          promptly commenced and is diligently pursuing such cure;

               3.   If the leasehold interest of Tenant is levied upon under
          execution or is attached under process of law, which levy or
          attachment continues for a period of thirty (30) days;

<Page>

               4.   If Tenant shall generally not pay its debts as they become
          due or shall admit in writing its inability to pay its debts or shall
          make a general assignment for the benefit of creditors;

               5.   If Tenant shall commence any case, proceeding or other
          action seeking reorganization, arrangement, adjustment, liquidation,
          dissolution or composition of it or its debts under any law relating
          to bankruptcy, insolvency, reorganization or relief of debtors, or
          seeking appointment of a receiver, trustee, custodian or other similar
          official for it or for all or any substantial part of its property;

               6.   If Tenant shall take any corporate or other action to
          authorize any of the actions set forth above in SUBPARAGRAPHS A(4) and
          A(5) of this PARAGRAPH 16; or

               7.   If any case, proceeding or other action against Tenant shall
          be commenced seeking to have an order for relief entered against it as
          debtor, or seeking reorganization, arrangement, adjustment,
          liquidation, dissolution or composition of it or its debts under any
          law relating to bankruptcy, insolvency, reorganization or relief of
          debtors, or seeking appointment of a receiver, trustee, custodian or
          other similar official for it or for all or any substantial part of
          its property, and such case, proceeding or other action (i) which
          results in the entry of an order for relief against it which is not
          fully stayed within seven (7) business days after the entry thereof or
          (ii) which is not dismissed for a period of thirty (30) days.

     B.   LANDLORD'S REMEDIES.

               1.   Upon the occurrence of any one or more Defaults by Tenant,
          Landlord may elect to terminate this Lease and Tenant's right to
          possession of the Premises. Upon any termination of this Lease,
          whether by lapse of time or otherwise, Tenant shall surrender
          possession and vacate the Premises and deliver possession thereof to
          Landlord. In such event, Tenant hereby grants to Landlord full and
          free license (a) to enter into and upon the Premises with or without
          process of law, (b) to repossess the Premises, (c) to expel or remove
          Tenant and any others who may be occupying or be within the Premises,
          and (d) to remove any and all property therefrom using such force as
          may be necessary without being deemed in any manner guilty of
          trespass, eviction or forcible entry or detainer, and without
          relinquishing Landlord's rights to Rent or any other right given to
          Landlord hereunder or by operation of law.

               2.   Landlord may but shall not be obligated to cure any Default
          by Tenant hereunder. If Landlord so elects, all costs and expenses
          paid by Landlord in curing such Default and reasonable legal fees in
          connection therewith shall be additional rent due on the next rent
          date.

<Page>

               3.   Notwithstanding anything in the Lease to the contrary, any
          and all remedies set forth in this Lease (i) shall be in addition to
          any and all other remedies Landlord may have at law or in equity, (ii)
          shall be cumulative, and (iii) may be pursued successively or
          concurrently as the Landlord may elect. The waiver by Landlord of any
          breach of any term, covenant or condition herein contained shall not
          be deemed to be a waiver of such term, covenant or condition or any
          subsequent breach of the same, or any other term, covenant or
          condition herein contained. Neither the acceptance of Rent nor any
          other action or omission of Landlord at any time or times after the
          happening of any breach by Tenant of any term, covenant or condition
          of this Lease, shall operate as a waiver of any past or future breach
          of any term, covenant or condition hereof or to deprive Landlord of
          its right to exercise its remedies on account of such breach, or be
          construed so as to at any future time estop Landlord from promptly
          exercising any other option, right or remedy that it may have under
          any term or provision of this Lease.

     C.   LANDLORD'S DEFAULT AND TENANT'S REMEDIES. If Landlord fails to observe
or perform any material covenant, agreement or obligation to be performed by
Landlord under this Lease, and if such failure shall continue for more than
thirty (30) days after notice thereof from Tenant to Landlord (unless such
failure requires work to be performed, acts to be done, or conditions to be
removed which, by their nature, cannot reasonably be performed, done or removed,
as the case may be, within such period, in which event, if the Landlord shall
have commenced curing or correcting the same within such period and shall have
diligently prosecuted such cure, or correction, such thirty (30) day period
shall be extended by such additional time period as may be reasonably required
for Landlord to cure or correct such failure), then Tenant shall have and may
exercise such rights and remedies to which it may be entitled at law or in
equity upon such default of Landlord, including, but not limited to, the right
to expend amounts necessary to cure such Default and to deduct such amounts from
Rent payments due Landlord.

     17.  NOTICES. All notices or other communications under this Lease must be
in writing and shall be deemed to be duly given (a) when delivered in person,
(b) upon transmission via confirmed facsimile transmission, provided that such
transmission is followed by delivery of a physical copy thereof in person, via
U.S. first class mail, or via a private express mail courier, or (c) two (2)
days after deposit with a private express mail courier, in any such case
addressed as provided in PARAGRAPHS 5 and 6 of the Lease Schedule. Any Party
may, by notice to the other Party, change the address to which such notices are
to be given.

     18.  HOLDING OVER. In the event Tenant remains in possession of the
Premises or any part thereof after the expiration of this Lease, without a
written lease, Tenant shall be deemed to be occupying the Premises as a tenant
from month-to-month subject to all of the conditions, provisions and obligations
of this Lease insofar as they may be applicable to such month-to-month tenancy,
except as provided in this PARAGRAPH 18. During such holding over, Tenant shall
pay Rent at one hundred twenty five percent (125%) the rate payable for the year
immediately preceding said holding over computed on a monthly basis for the time
Tenant thus remains in

<Page>

possession. The provisions of this Paragraph do not waive Landlord's rights of
re-entry or right to regain possession by actions at law or in equity or by any
other rights hereunder.

     19.  SUCCESSORS OR ASSIGNS. This Lease shall be binding upon and inure to
the benefit of the Parties hereto, and their respective successors and permitted
assigns.

     20.  SUBORDINATION. Tenant agrees that this Lease shall be subordinate in
interest to any mortgage or ground lease covering the Building now in effect or
hereafter given by Landlord or others provided that so long as Tenant is not in
default hereunder, this Lease shall remain in full force and effect and Tenant's
possession of the Premises shall not be disturbed. Tenant agrees at Landlord's
request to execute an appropriate instrument confirming its subordination in
exchange for a written non-disturbance agreement executed by any such lender or
ground lessor in a form as may be reasonably acceptable to Tenant.

     21.  QUIET ENJOYMENT. Landlord covenants that Tenant, on paying the Rent
and performing Tenant's obligations under this Lease, shall peaceably have, hold
and enjoy the Premises for the Term without any hindrance by or through
Landlord, or its successors or assigns.

     22.  PARKING. Tenant and its employees, guests and visitors shall be
permitted to park, along with other tenants of the Building, their employees,
guests and visitors in parking areas adjacent to the Building in accordance with
Landlord's standard parking procedures.

     23.  SALE BY LANDLORD. In the event of an arms length sale or conveyance by
Landlord to an unrelated third party of Landlord's interest in the Building or
in this Lease, the same shall operate to release Landlord from any future
liability under this Lease accruing from and after such transfer. Tenant agrees
to look solely to the successor in interest of Landlord in and to this Lease for
the performance of Landlord's covenants and obligations.

     24.  ESTOPPEL CERTIFICATE. Tenant shall, at the request of Landlord at any
time and from time to time upon not less than ten (10) business days' prior
written notice, furnish to Landlord, or an entity designated by Landlord, a
certificate stating (i) that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease, as so modified, is in full force and effect), (ii) the dates to
which the Rent and other charges are paid, (iii) that Tenant is in possession
and paying Rent on a current basis with no offsets, defenses or claims, (iv)
that there are not any uncured defaults on the part of Tenant and to Tenant's
knowledge, on the part of Landlord, under the Lease (or specifying such
defaults, if any are claimed) and (v) such other matters as Landlord may
reasonably require or that any prospective purchaser, mortgagee or ground lessor
may require.

     25.  TRANSFER OF PERSONAL PROPERTY, EQUIPMENT AND TRADE FIXTURES. In
consideration of Tenant's obligations and covenants hereunder, Landlord hereby
sells, assigns, transfers and conveys to Tenant all of its right, title and
interest in and to the personal property, equipment and trade fixtures located
on the Premises as of the Effective Date. From and after the Effective Date, all
personal property, equipment and trade fixtures located on the Premises shall be
deemed the property of Tenant.

<Page>

     26.  HAZARDOUS MATERIALS. Prior to executing this Lease, Tenant has
completed, executed and delivered to Landlord a Hazardous Materials Disclosure
Certificate ("Initial Disclosure Certificate") a fully completed copy of which
is attached hereto as EXHIBIT E and incorporated herein by this reference.
Tenant covenants, represents and warrants to Landlord that the information on
the Initial Disclosure Certificate is true and correct and accurately describes
all Hazardous Materials (as defined below) which will be manufactured, treated,
used, handled, transported or stored on or about the Premises by Tenant or
Tenant's agents. Tenant shall on each anniversary of the Commencement Date and
at such other times as Tenant desires to manufacture, treat, use, handle,
transport or store on or about the Premises new or additional Hazardous
Materials which were not listed on the Initial Disclosure Certificate, complete,
execute and deliver to Landlord an updated Disclosure Certificate (each, an
"Updated Disclosure Certificate") describing the then current and proposed
future presence of Hazardous Materials on or about the Premises, which Updated
Disclosure Certificate shall be in the same format as that which is set forth in
EXHIBIT E or in such updated format as Landlord may require from time to time.
Tenant shall deliver an Updated Disclosure Certificate to Landlord not less than
thirty (30) days prior to the date Tenant intends to commence the manufacture,
treatment, use, handling, transportation or storage of new or additional
Hazardous Materials on or about the Premises, and Landlord shall have the right
to approve or disapprove such new or additional Hazardous Materials in its sole
and absolute discretion. Tenant shall not allow the presence of Hazardous
Materials on or about the Premises except as described in the Initial Disclosure
Certificate or as otherwise approved by Landlord in writing in accordance with
this PARAGRAPH 26, which approval shall not be withheld if consistent with
Landlord's past practice on the Premises.

     Tenant shall not cause or permit any Hazardous Material to be generated,
produced, brought upon, used, stored, treated or disposed of in or about the
Premises by Tenant, its agents, employees, contractors, sublessees or invitees
without (a) the prior written consent of Landlord, which consent shall not be
unreasonably withheld, and (b) complying with all applicable federal, state and
local laws and ordinances pertaining to the transportation, storage, use,
treatment, handling, manufacture or disposal of such Hazardous Materials,
including but not limited to obtaining and complying with proper licenses and
permits. Landlord shall be entitled to take into account such other factors or
facts as Landlord may reasonably determine to be relevant in determining whether
to grant or withhold consent to Tenant's proposed activity with respect to
Hazardous Material. In no event, however, shall Landlord be required to consent
to the installation or use of any underground storage tanks.

     If, during the Term, the treatment, handling, manufacture, transportation,
storage, use, release or disposal of Hazardous Materials on the Premises results
in the contamination of leasehold improvements (including buildings), equipment,
soil or surface or ground water or loss or damage to Person(s) or property, then
Tenant agrees to: (a) notify Landlord immediately of any contamination, claim of
contamination, loss or damage, (b) after consultation with the Landlord, clean
up the contamination in full compliance with all applicable statutes,
