The second floor of the building (the “Building”) located at 441 Charmany Drive, Madison, Dane County, Wisconsin, consisting of approximately 17,500 rentable square feet of space (herein referred to as the “Leased Premises”) and all Common Area (defined below) situated upon the property described in Exhibit A attached hereto (the Property described in Exhibit A is referred to herein as the “Landlord’s Property”). The location of the Leased Premises on the Landlord’s Property is indicated on the map attached hereto as Exhibit B-1, and the floor plan attached hereto as Exhibit B-2.

1.2.         Term of Lease.  The term of this Lease (“the Term”) shall begin on November 1, 2009 (“the Commencement Date”) and, unless otherwise terminated in accordance with the terms of this Lease, shall end at midnight on October 31, 2014 and, as applicable, shall include the Extended Term (as hereinafter defined).  In addition, Tenant shall have one (1) option to extend the Term for a period of five (5) years (the “Extended Term”).  If Tenant exercises its option, the resulting Extended Term shall begin upon the expiration of the original Term, and all terms, covenants and provisions of this Lease shall apply during the Extended Term with the exception that (i) Tenant shall not have any further option to extend the Term; and (ii) base rent shall be due and payable as provided in Section 2.1 below.  If Tenant elects to exercise its option to extend, provided this Lease is in full force and effect and Tenant has performed all of the terms, covenants and provisions hereof on Tenant’s part to be performed, Tenant shall do so only by giving Landlord notice in writing of its intention to exercise its option to extend not later than six (6) months prior to the expiration of the original Term.  If at any time during the Term, Tenant vacates the Leased Premises, Tenant shall automatically forfeit its option to extend the Term as more particularly described herein.

1.3.         Condition of Leased Premises.  Landlord shall deliver, and Tenant shall accept the Leased Premises in AS-IS, WHERE-IS condition without any representations and/or warranties with respect to said condition.  Notwithstanding the foregoing, Landlord shall service,

2

as necessary, as of the Commencement Date, the roof of the Building and the HVAC system, electrical and plumbing systems exclusively serving the Leased Premises so that same shall be in good order, condition and repair as of the Commencement Date.  In addition, in order to separate the Leased Premises from other tenant spaces located within the Building, Landlord shall: (i) install locks on the doors located at the top of the east and west stairwells serving the Leased Premises on or before the Commencement Date; and (ii) install three (3) additional doors in the lobby located on the first floor of the Building on or before the date that is three (3) months after the Commencement Date.

1.4.         Security Deposit.  Tenant shall pay to Landlord upon execution of this Lease the sum of Twenty-One Thousand Eight Hundred Seventy-Five and No/100 Dollars ($21,875.00) as security for the performance of the obligations hereof by Tenant, payable in the form of cash or equivalent.  This security deposit shall be returned to Tenant within thirty (30) days following the termination of this Lease, less any amount appropriately applied by Landlord to cure a Tenant default.

2.  RENT

2.1.         Base Rent.  Tenant shall pay to Landlord at its office in Madison, Wisconsin, or such other place as Landlord may designate in writing, and without any deduction or offset whatsoever, as base rent, the following amounts in advance on or before the first day of each calendar month during the period indicated:

*The base rent listed above reflects annual increases of two and one-half percent (2.5%) annually.  The first such annual increase shall occur on November 1, 2010 and shall occur annually on each November 1 thereafter occurring during the Term, including without limitation, the Extended Term, if applicable.  If, during the Term,  Landlord and Tenant agree to an expansion of the Leased Premises, the base rent  per square foot due and payable with respect to such expansion of the Leased Premises shall be at the same rate as the base rent per square foot then due and payable under this Lease.

If the Term does not commence on the first day of a calendar month, the base rent for such fractional month shall be computed pro rata on the basis of thirty (30) days per month and paid to Landlord on the first day of the next succeeding calendar month along with the rent for such succeeding month.

3

2.2.         Additional Rent.  During the Term, in addition to base rent, Tenant shall pay as part of the consideration for this Lease and as additional rent, hereinafter designated “additional rent,” all additional amounts hereinafter provided for and the same shall be payable upon Landlord’s demand except as otherwise expressly provided, including, but not limited to Tenant’s Proportionate Share, as defined in Section 5.6. of real estate taxes, Common Area charges, and Tenant’s Proportionate Share of Landlord’s insurance and utilities.  Landlord reserves the right to deviate from the estimates so that the amounts due as additional rent for the Leased Premises are consistent with the amounts due as additional rent as determined by the more detailed provisions pertaining thereto within this Lease.  Consistent with the forgoing, Tenant agrees to pay those amounts, if any, in excess of the estimates set forth above.

2.3.         Past Due Rent.  If Tenant shall fail to pay when due any base rent or additional rent, and such amount shall not be paid within ten (10) days after the date when due, such unpaid amounts shall bear interest from the due date thereof to the date of payment at the rate of ten percent (10%) per annum or the prime interest rate then charged by the U.S. Bank National Association or its successors or assigns, whichever is greater.

2.4.         Real Estate Taxes.  Landlord shall pay all general taxes on Landlord’s Property, including all general real estate taxes, personal property taxes on Landlord’s personal property located at Landlord’s Property and installments for special assessments arising during the Term.  Tenant agrees to reimburse Landlord for Tenant’s Proportionate Share of such taxes and assessments.

Tenant’s obligation for each tax described in this section shall be further prorated for the first year of this Lease between Landlord and Tenant as of the Commencement Date of this Lease. Tenant’s obligation for each tax described in this section shall be further prorated for the last year of the Term as of the last day of the Term.

Tenant shall, upon notice from Landlord, pay in escrow to Landlord one-twelfth (1/12) its Proportionate Share of the estimated annual real estate taxes, personal property taxes and installments for special assessments for Landlord’s Property on the first day of each month after such request, provided, however, that if the sum of such installments shall be less than the total amount of Tenant’s Proportionate Share of such taxes, Tenant shall pay such deficiency at least ten (10) days in advance of the due date of such taxes, taking into account any installment payment arrangements offered by the taxing authority without the imposition of any finance charge, penalty or other cost.  Tenant’s escrow payment shall be applied by Landlord to the payment of the taxes on the Landlord’s Property.  At the termination of this Lease, Tenant shall promptly pay Landlord for Tenant’s Proportionate Share of the estimated taxes based upon that portion of the termination year that exceeds the amount of tax payments from Tenant then held in escrow.  Such estimate shall be based upon the taxes for the preceding year.  Any payment by Tenant in excess of its Proportionate Share of taxes for any tax year shall be refunded to Tenant within ninety (90) days after the expiration of such tax year.

For the purpose of this Section 2.4, Tenant’s Proportionate Share shall be calculated by dividing the rentable square footage of the Leased Premises by the rentable square footage of all buildings located from time to time on Landlord’s Property.

3.  INSTALLATIONS, REPAIRS AND

MAINTENANCE OF LEASED PREMISES

3.1.         Maintenance by Tenant.  Tenant shall at all times keep the Leased Premises and all partitions, doors, fixtures, equipment and appurtenances thereof (including but not limited to electrical, lighting, HVAC, and plumbing equipment, lines and fixtures servicing only the Leased Premises) in good order, condition and repair, reasonable wear and tear excepted. If Tenant refuses or neglects to repair property as required hereunder and to the reasonable satisfaction of Landlord as soon as reasonably possible after written demand, Landlord may make such repairs without liability to Tenant for any loss or damage that may accrue to Tenant’s property or to Tenant’s business by reason thereof and upon completion thereof, Tenant shall pay Landlord’s costs for making such repairs plus twenty percent (20%) for overhead, upon presentation of bill therefor, as additional rent. When used in this section, the term “repairs” shall include replacements and renewals when necessary and all such repairs shall be equal in quality and class of original work.

3.2.         Maintenance by Landlord.  Landlord shall keep foundations, exterior walls, roof and all other interior and exterior structural members of the Leased Premises and all Common Areas including, shared use equipment and any electrical, HVAC, and plumbing lines and equipment not exclusively servicing the Leased Premises (all of which shall be considered as part of the Common Areas) in good repair and shall have access to the Leased Premises for such purpose, but Landlord shall not be required to make any such repairs which become necessary or desirable by reason of the negligence of Tenant, its agents, servants, employees or customers.  Landlord shall enter into service contracts on all heating, ventilating and air conditioning units, including but not limited to changing filters, checking belts and oiling of units.  Tenant shall pay its Proportionate Share of the cost of such contracts as a Common Area charge pursuant to Section 5.5.

3.3.         Signs.  Upon completion of the multi-tenant monument sign located immediately adjacent to the Building (the “Monument Sign”), Tenant shall, subject to the terms and conditions of this Section 3.3, have the right to install its sign panel on the Monument Sign in the location designated by Landlord.  Landlord shall make available suite number signage and lobby directory signage.  All exterior signs to be installed by Tenant shall be approved in advance in writing by the Design Review Board appointed by the Board of Regents of the University of Wisconsin System. All signs to be installed by Landlord shall be approved in advance in writing by the Design Review Board.

Tenant shall remove all signs installed by Tenant at the termination of this Lease. Such installations and removals shall be made in such a manner as to avoid injury, defacement or any other damages to the buildings and improvements. The cost of repairing any damage to the building caused by the installation, removal, or maintenance of the sign shall be borne by the Tenant.

The cost of all signs, other than those furnished by Landlord, including the installation, maintenance, and removal thereof, shall be the responsibility of the Tenant.

5

3.4.         Alterations, Changes and Installations by Tenant.  Tenant shall not make or cause to be made any alterations, additions or improvements (collectively, “Alterations”) to the Leased Premises, or cause to be installed any fixtures, interior or exterior lighting, plumbing equipment or mechanical equipment within the Leased Premises or any Common Areas without the prior written consent of Landlord, not to be unreasonably withheld, conditioned or delayed.  Any such Alterations shall be made by Tenant, at Tenant’s sole cost and expense, using a competitive bid process.  With respect to the making of any such Alterations, Tenant, at Tenant’s sole cost and expense, shall hire a general contractor, which general contractor shall be subject to Landlord’s approval, not to be unreasonably withheld, conditioned or delayed.

3.5.         Fixtures and Equipment.  Subject to Section 3.4, Tenant may, at its own expense, furnish and install such business and trade fixtures in and on the Leased Premises as may be necessary or desirable for Tenant’s business. Upon expiration of this Lease, Tenant may remove such business and trade fixtures provided that Tenant shall promptly repair any damage caused by their removal.  Landlord and Tenant acknowledge that all business and trade fixtures located within the Leased Premises prior to the Commencement Date that are not installed by Tenant are the property of the Landlord.  Tenant may, at its own expense, install equipment within the Leased Premises and such equipment shall remain the property of Tenant and shall be removed by Tenant upon the termination of this Lease.

3.6.         Liens and Obligations.  Tenant agrees not to create or to permit others to create any lien or obligations against Landlord or the Leased Premises in making alterations, repairs or in installing materials, fixtures or equipment.  If a lien or obligation is claimed against Landlord or the Leased Premises, Tenant shall either (a) provide Landlord with a bond in the amount of that claim, or (b) cause that claim to be released.  Tenant further agrees to hold Landlord harmless from all claims and demands by any third party in any manner connected with such alterations, repairs or installations or with Tenant’s occupancy for such purpose.  Tenant shall comply with all laws and all directions, rules and regulations of all governmental regulatory bodies or officials having jurisdiction over such alterations, repairs or installations, except that Tenant shall not be required to comply with any laws, regulations or orders by governmental authority necessitating structural alterations, changes, repairs or additions, unless made necessary by the act or work performed by Tenant, in which case Tenant shall so comply, at its own expense, after first procuring the written consent of Landlord.

4.  CONDUCT OF BUSINESS

4.1.         Business Use.  It is understood and agreed that the Leased Premises shall be used and occupied by Tenant for general office, laboratory, and storage purposes. Tenant shall not use the Leased Premises for any use not identified as a permitted use by any zoning ordinance or other governmental regulation relating to the Leased Premises or approved as a conditional use by the governmental bodies having zoning authority. No use shall be permitted, or acts done, which will cause a cancellation of any insurance policy covering the Leased Premises. Tenant shall not sell, permit to be kept, used or sold in or about the Leased Premises any article which may be prohibited by the standard form of fire insurance policy. In the event Tenant’s use of the Leased Premises results in an increase in the cost of any insurance relating to the Landlord’s Property, Tenant shall pay such additional cost to Landlord upon demand. Tenant shall comply with all applicable laws, ordinances, regulations, and/or deed and plat restrictions affecting the

6

use and occupancy of the Leased Premises. Tenant shall not commit, or permit to be committed, any waste or nuisance on the Leased Premises.

4.2.         Utility Charges.  Landlord shall furnish to the Leased Premises heat, gas, sewer, electricity and other utilities.  Tenant shall be solely responsible for and promptly pay all charges for heat, water, gas, sewer, electricity or any other utility used or consumed in the Leased Premises, including supplemental heating. In the event utilities are not separately metered, Tenant shall pay Tenant’s Proportionate Share of utility costs for the Leased Premises.  For the purpose of this Section 4.2., Tenant’s Proportionate Share shall be calculated by dividing the rentable square footage of the Leased Premises by the rentable square footage of the building in which the Leased Premises is located or another appropriate allocation method which fairly allocates utility costs between tenants in the building based on differing usage, e.g. laboratory versus office use.  In addition, during those portions of the Term in which the first floor of the Building (the “First Floor”) is leased to EMD Chemicals Inc. (“EMD”) but is not occupied, Landlord and Tenant hereby acknowledge and agree that (i) Landlord shall have the right to allocate the utility costs of the Building as Landlord deems reasonably appropriate based upon those portions of the Building that are then-currently occupied; and (ii) in no event shall the utility costs allocated to the unoccupied portion of the First Floor exceed $1.25 per square foot per annum.  In no event shall Landlord be liable for an interruption or failure in the supply of any such utilities to the Leased Premises.

4.3.         Taxes on Leasehold.  Tenant shall be responsible for and shall pay before delinquency all municipal, county, state, or other taxes assessed during the Term against any leasehold interest or personal property of any kind, owned by or placed in, upon or about Leased Premises by Tenant.

4.4.         Assignment or Subletting.  Tenant shall have the right to assign this Lease to (a) any affiliate of Tenant; (b) to the entity resulting from any corporate reorganization to which Tenant is a party; (c) any entity resulting from a merger; or (d) to an entity purchasing substantially all of the assets of Tenant, provided such an assignment shall not release Tenant from the covenant to pay rent or any other covenant owed by Tenant to Landlord under this Lease.  Except as provided in (a), (b), (c) and (d) preceding, Tenant agrees not to sell, assign, mortgage, pledge or in any manner transfer this Lease or any estate or interest thereunder and not to sublet the Leased Premises or any part or parts thereof without the prior written consent of Landlord in each instance which consent shall not be unreasonably withheld, conditioned or delayed.  Notwithstanding anything to the contrary set forth herein, Landlord hereby grants its consent to a sublease (the “Aldevron Sublease”) of all or any portion of the Leased Premises by Tenant, as sublessor, to Aldevron LLC, as sublessee.  Landlord’s consent to the Aldevron Sublease does not constitute a consent to any subsequent subletting or assignment and does not relieve Tenant or any person claiming under or through Tenant of the obligation to obtain the consent of Landlord with respect to any future assignment or sublease.  One hundred percent (100%) of any consideration paid to Tenant for a sublease or assignment that exceeds the amount Tenant must pay Landlord under this Lease (the “Excess Consideration”) shall be paid to Landlord.  Where a part of the Leased Premises is subleased or assigned, there shall be a prorating of the rent payable under this Lease and the rent payable under the assignment or the sublease to determine whether Excess Consideration is payable to Landlord.  Excess Consideration shall exclude reasonable leasing commissions paid by Tenant, payments

7

attributable to the amortization of the cost of Tenant improvements made to the Leased Premises at Tenant’s cost for the assignee or subtenant, and other reasonable, actual cash out-of-pocket costs paid by Tenant, such as attorneys’ fees directly related to Tenant’s obtaining an assignee or sublease.  Tenant shall pay this Excess Consideration to Landlord at the end of each calendar year during which Tenant collects any Excess Consideration.  Each payment shall be sent with a detailed statement showing the total consideration paid by the subtenant or assignee and any exclusions from consideration permitted by this section.

Consent by Landlord to one assignment of this Lease or to one licensing or subletting of the Leased Premises shall not be a waiver of Landlord’s rights hereunder as to subsequent assignment or subletting, or act to release any guaranty of this Lease, Landlord’s rights to assign this Lease are and shall remain unqualified.  Furthermore, Landlord’s consent to any assignment or sublease shall not, in the absence of language to the contrary contained within said assignment or sublease, release Tenant from the covenant to pay rent or any other covenant owed by Tenant to Landlord under this Lease.

4.5.         Corporate Ownership.  If the Tenant is a corporation and if at any time during the Term any part or all of the corporate shares of said corporation shall be transferred by sale, assignment, operation or law or other disposition (except transfers by gift, bequest or inheritance) so that the result of such transfer would be the loss of voting control of said corporation by the person or persons owning a majority of said corporate shares at the date of this Lease, the Tenant shall notify the Landlord in writing of such changes in voting control and Landlord may terminate this Lease by giving Tenant written notice of such termination within ninety (90) days after receipt of Tenant’s notice. This section, however, shall not apply if on the date this Lease is executed the Tenant is a corporation, the outstanding common stock of which is listed on a recognized security exchange, or if at least eighty percent (80%) of the Tenant’s stock is owned by another corporation, the common stock of which is so listed.

4.6.         Rules and Regulations.  The rules and regulations appended to this Lease as Exhibit C are hereby made a part of this Lease.  The rules and regulations adopted by the Landlord shall be in writing and provided to Tenant in order to be effective.  Tenant agrees to comply with and observe the rules and regulations. Tenant’s failure to keep and observe said rules and regulations shall constitute a breach of the terms of this Lease in the manner as if the same were contained herein as covenants. Landlord reserves the right from time to time to amend or supplement said rules and regulations and to adopt and promulgate additional rules and regulations applicable to Leased Premises, and the property described in Exhibit A, provided that such additional rules and regulations apply equally to all lessees with the project and do not unreasonably interfere with Tenant’s use and enjoyment of the Leased Premises. Any such additional rules and regulations, and amendments and supplements, if any, shall be given to Tenant in writing, and Tenant agrees thereupon to comply with and observe all such rules and regulations and amendments thereto and supplements thereof.

4.7.         Surrender.  On the last day of the Term, including any option term, or upon the sooner termination thereof, Tenant shall peaceably and quietly surrender the Leased Premises and all improvements thereon in the same condition as at the commencement of this Lease, in good order, condition and repair, fire and other unavoidable casualty, and reasonable wear and tear excepted. All alterations, additions, and improvements other than business and trade fixtures

8

which may be made or installed by either Landlord or Tenant upon the Leased Premises or in common areas including business and trade fixtures installed by Tenant pursuant to Section 3.5, shall remain the property of Landlord and shall remain upon and be surrendered without disturbance, molestation or injury at the termination of the Term, whether by the elapse of time or otherwise, all without compensation or credit to Tenant. Tenant shall remove all equipment and personal property and shall repair any damage occasioned by such removal.  Any personal property not removed by Tenant shall be deemed abandoned and shall become the property of Landlord; provided, that the Landlord shall have the option to effect said removals and Tenant shall pay Landlord, on demand, the cost of removal thereof, with interest at the rate of ten (10%) percent per annum from the date of such removal by Landlord, or the prime interest rate established by U.S. Bank National Association or its successors or assigns, whichever is higher.

The delivery to Landlord at the place then fixed for the payment of rent of the keys to the Leased Premises shall constitute surrender of the premises by Tenant and acceptance of the keys by Landlord shall constitute acceptance by Landlord of such surrender. Such acceptance by Landlord shall not constitute a waiver of any rights to recover damages under terms of this Lease. This method of surrender shall not be exclusive and shall be in addition to all other methods of surrender.

Anything in this section to the contrary notwithstanding, at any termination of this Lease, Landlord shall have a lien upon all of the property of Tenant then located in or upon the Leased Premises to secure the payment of any amounts due from Tenant to Landlord by reason of this Lease or to secure the payment of damages, and Landlord may retain possession of such property until payment in full of said amounts. Said lien shall not be defeated by placing such property in storage. If Tenant has not redeemed said property within ninety (90) days after the termination of said Lease, Landlord may sell such property at public or private sale without further notice to Tenant, and shall apply in a reasonable manner determined by Landlord the proceeds of sale to reduce the amounts then owed from Tenant to Landlord.

5.  COMMON USE AREAS AND FACILITIES

5.1.         Common Area.  As used herein, “Common Area” shall include those improvements on and all areas within Landlord’s Property which are designed for common use and benefit, exclusive of space in buildings (or any additional buildings) designed for rental to tenants as the same may exist from time to time. Landlord reserves the right to change building perimeters, add additional buildings, drives, or other structures and to make other changes desired, provided that reasonable access to and use of the Leased Premises is provided and Landlord uses reasonable measures to minimize any disruption or interruption to the conduct of Tenant’s business operations at the Premises.

5.2.         Use of Common Area.  Landlord hereby grants to Tenant, its employees, agents, customers and invitees, the nonexclusive right during the Term to use the Common Areas and all equipment and fixtures therein as the same may exist from time to time, such use to be in common with Landlord and all tenants of Landlord from time to time, its and their employees, agents, customers and invitees, except when the same are being repaired.

9

5.3.         Operation and Maintenance.  The Common Area shall at all times be subject to the exclusive control and management of Landlord and Landlord shall manage, operate, repair and maintain the Common Area and its facilities in a clean and sightly condition. The manner in which such area and facilities shall be maintained and the expenditures therefor shall be at the Landlord’s sole discretion.  Landlord reserves the right to add and remove equipment and fixtures from the Common Areas in its sole discretion.

5.4.         Preventing Public Rights.  If Landlord deems it necessary in order to prevent the acquisition of special rights, Landlord may from time to time close all or any portion of the Common Area or take such action as shall be reasonably appropriate for that purpose.

5.5.         Charge for Common Area and Facilities.  During the Term, Tenant shall pay to Landlord an annual charge which shall be Tenant’s Proportionate Share of the Landlord’s actual cost of operating, repairing, and maintaining the Common Area and other facilities which shall include, but shall not be limited to common conference rooms, kitchen areas, hallways and lobbies, driveways, parking areas, landscaped and vacant areas, area-ways, walks, curbs, corridors, gardens, sanitary and storm sewers, signs, public facilities such as washrooms, drinking fountains, toilets, the cost of operating, repairing, lighting, heating, air conditioning, cleaning, painting, removing of snow, ice and debris, policing and inspecting, insurance for hazards and other risks, maintenance including but not limited to such repair of paving, curbs, walkways, driveways, landscaping and drainage and lighting facilities as may be necessary from time to time to keep the same in good condition and repair, a reasonable allowance for the depreciation of maintenance equipment, a reasonable allowance for Landlord’s overhead costs in conjunction with the foregoing, and all costs and expenses other than those of a capital nature, but excluding legal fees recovered by Tenant from Landlord in any litigation relating to this Lease. Landlord reserves the right to charge separate and reasonable user fees for certain equipment and fixtures located in the Common Areas.  Landlord shall provide Tenant with an itemized statement of Common Area costs and user fees.

Tenant shall have the right, upon not less than ten business days notice, to audit Landlord’s records regarding the Common Area Costs provided (i) the audit is conducted at Landlord’s home office during Landlord’s normal business hours; and (ii) the audit is done at Tenant’s sole cost and expense.  Tenant shall deliver to Landlord a copy of the results of the audit within ten days of its receipt by Tenant.

5.6.         Formula For Proportionate Share.  The annual charge for Common Area maintenance and facilities shall be computed on the basis of twelve (12) consecutive calendar months commencing and ending on dates designated by the Landlord and shall be paid in advance in monthly installments on the first day of each calendar month in an amount estimated by Landlord. Within sixty (60) days after the end of each such twelve (12) month period, Landlord shall determine and furnish to Tenant a computation of the actual amount charged for such period; and the amounts so estimated and paid during such period shall be adjusted promptly (including adjustments on a pro rata basis for any partial such period at either end of the Term) by one party’s paying to the other whatever amount is necessary to effectuate such adjustment.  Tenant, at Tenant’s sole cost and expense, shall have the right to conduct an audit of Common Area maintenance and facilities charges.  Any such audit shall be limited to the current year and the two (2) previous years.  In the event the audit reveals a discrepancy, Landlord and

10

Tenant shall work together diligently to resolve such discrepancy in a timely and equitable manner.

The Tenant’s Proportionate Share of the Landlord’s actual costs defined in this Article which are applicable to all tenants occupying space on Landlord’s Property shall be that proportion which the rentable area in the Leased Premises bears to the total rentable area in the buildings located from time to time on the Landlord’s Property.  If Landlord restricts use of certain Common Areas or equipment and fixtures within Common Areas to Tenant’s dwelling or buildings in which such Common Areas are located, the expenses of such Common Areas shall be allocated among tenants of that particular building or buildings, not all buildings on Landlord’s Property.  In that case, Tenant’s Proportionate Share shall be that portion which the rentable area in the Leased Premises bears to the total rentable area in the building or buildings to which the costs being allocated apply.

5.7.         Basis For Changes.  Changes in any particular floor area occurring during any calendar month shall be effective on the first day of the next succeeding calendar month and the amounts of any floor area in effect for the whole of any year shall be the average of the total amounts in effect on the first day of each calendar month in such year.

5.8.         Hazardous Materials.  Landlord represents and warrants that, as of Commencement Date there are no Hazardous Materials (as hereinafter defined) present in the Leased Premises or in, on or under Landlord’s Property.  Landlord agrees that the remediation, removal or neutralization, if and to the extent required by Environmental Regulations (as hereinafter defined), of any Hazardous Materials in the Leased Premises or in, on or under the Landlord’s Property shall be done by Landlord, at its sole cost and expense, if such Hazardous Materials discovered were not introduced in the Leased Premises or in, on or under the Landlord’s Property by Tenant, its agents, employees or contractors.  Tenant agrees that the remediation, removal or neutralization, if and to the extent required by Environmental Regulations, of any Hazardous Materials in the Leased Premises or in, on or under the Landlord’s Property shall be done by Tenant, at its sole cost and expense, if such Hazardous Materials discovered were introduced in the Leased Premises or in, on or under the Landlord’s Property by Tenant, its agents, employees or contractors.  “Hazardous Materials” shall mean (i) any waste, material or substance (whether in the form of a liquid, a solid, or a gas and whether or not air-borne) which is deemed to be a pollutant or a contaminant, or to be hazardous, toxic, ignitable, reactive, infectious, explosive, corrosive, dangerous, harmful or injurious to public health or to the environment, and which is now or becomes regulated in the future by or under the authority of any applicable local, state or federal laws, judgments, ordinances, orders, rules, regulations, codes or other governmental restrictions or requirements, any amendments or successor(s) thereto, replacements thereof or publications promulgated pursuant thereto, relating to environmental quality, health, safety, contamination and clean-up (collectively “Environmental Regulations”, and individually, “Environmental Regulation”); (ii) petroleum; (iii) asbestos and asbestos containing materials; (iv) any polychlorinated biphenyl; and (v) any radioactive material. Landlord and Tenant each agree that neither Landlord nor Tenant shall cause any Hazardous Materials to exist on, or to escape, seep, leak, spill or be discharged, emitted or released from Landlord’s Property during the Term in violation of any applicable Environmental Regulation.

11

5.9.         Landlord’s Indemnity.  Landlord hereby indemnifies Tenant, its successors and assigns, and their respective agents, contractors, employees, members, partners, officers, and directors (“Tenant Indemnified Parties”), and agrees to hold Tenant Indemnified Parties harmless from and against any and all losses, liabilities, damages, injuries, penalties, fines, costs, expenses and claims of any and every kind whatsoever, including reasonable attorney’s fees and costs (collectively “Environmental Liabilities”) paid, incurred or suffered by, or asserted against, Tenant Indemnified Parties with respect to, or as a direct or indirect result of, the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission or release from Landlord’s Property of any Hazardous Materials which was brought in to Landlord’s Property by Landlord, its agents, employees, or their respective predecessors-in-interest, or caused by breach by Landlord, its agents, employees or their respective predecessors-in-interest of any Environmental Regulation to which Landlord is subject, and/or which was located upon the Leased Premises or Landlord’s Property prior to the Commencement Date.  This indemnity shall survive the termination of this Lease.

5.10.       Tenant’s Indemnity.  Tenant hereby indemnifies Landlord, its successors and assigns, and their respective agents, contractors, employees, members, partners, officers, and directors (“Landlord Indemnified Parties”), and agrees to hold Landlord Indemnified Parties harmless from and against any and all Environmental Liabilities paid, incurred or suffered by, or asserted against, Landlord Indemnified Parties with respect to, or as a direct or indirect result of, the presence on or under, or the escape, seepage, leakage, spillage, discharge, emission or release from the Leased Premises or Landlord’s Property of any Hazardous Materials which was brought in to the Leased Premises or Landlord’s Property by Tenant, its agents or employees, or caused by breach by Tenant of any Environmental Regulation to which Tenant is subject.  This indemnity shall survive the termination of this Lease.

5.11.       Remediation.  In the event Hazardous Materials are or become present at Landlord’s Property as the result of any cause whatsoever (other than Hazardous Material which were brought in to the Leased Premises by Tenant, its agents, employees or invitees), and such presence of Hazardous Materials renders the Leased Premises Unusable (as hereinafter defined), then all rent shall be abated with respect to the portion of the Leased Premises so damaged until such time as the portion(s) of the Leased Premises so damaged are no longer rendered Unusable.  For the purpose of this subsection, “Unusable” means that the Tenant does not have access to all or any portion of the Leased Premises because of the enforcement of any Environmental Regulation or the need to use all or any portion of the Leased Premises for remediation of any Hazardous Materials, or because the use of the Leased Premises would represent a risk to the health or safety of Tenant, Tenant’s employees, agents or invitees.

6. INSURANCE

6.1.         Casualty Insurance.  Landlord shall at all times during the Term keep all improvements which are now or hereafter located on the Landlord’s Property insured against loss or damage by fire and the extended coverage hazards at full insurance value with loss payable to Landlord, Landlord’s mortgagee and such other parties as Landlord may designate, as their interests may appear.

12

Tenant agrees to reimburse Landlord for Tenant’s Proportionate Share of the cost of such insurance.

6.3.         Tenant’s Contents.  Tenant shall be responsible for obtaining such insurance as it may deem advisable for all property located in the Leased Premises and in common areas. It is understood that the insurance carried by Landlord does not cover the risk of loss or damage to Tenant’s property.

6.4.         Increase in Fire Insurance.  Tenant agrees that it will not keep or use, in or upon the Leased Premises any article which may be prohibited by the standard form fire insurance policy. If Tenant’s use or occupancy causes any increase in premiums for fire or casualty insurance on the Landlord’s Property, or the Leased Premises, or any part thereof, above the rate of the least hazardous type of occupancy legally permitted in the Leased Premises, Tenant shall pay the additional premium on such insurance. No part of such additional premium resulting from the use or occupancy of another tenant shall be charged to Tenant under Sections 6.1 and/or 6.2 of this Lease. The Tenant shall also pay in such event any additional premium on any rent insurance policy that may be carried by the Landlord for its protection against rent loss through fire or other casualty. Bills for such additional premiums shall be rendered by Landlord to Tenant at such times as Landlord may elect, and shall be due and payable by Tenant when rendered, and the amount thereof shall be deemed to be, and be paid as, additional rent.

13

8.1.         Total Condemnation.  In the event that the Leased Premises or such part of the Leased Premises as will render the remainder untenantable, shall be appropriated or taken under the power of eminent domain by any public or quasi-public authority, this Lease shall terminate and expire as of the date of taking.

8.2.         Partial Condemnation.  In the event of any other partial condemnation, Tenant shall have the option of terminating this Lease on the effective date of such condemnation by written notice to Landlord prior to such effective date, unless Landlord shall provide to Tenant within a reasonable time after such effective date reasonably comparable space to that taken.  For purposes of this Section, reasonably comparable space shall mean space which is in the same general area as that condemned, is in a similar type of building and contains a similar floor plan, and is leased on similar economic and other terms as this Lease.

8.3.         Landlord’s Damages.  In the event of any condemnation or taking, whether whole or partial, the Tenant shall not be entitled to any part of the award paid for such condemnation and Landlord is to receive the full amount of such award.

8.4.         Tenant’s Damages.  Although all damages in the event of any condemnation are to belong to the Landlord whether such damages are awarded as compensation for diminution in value of the leasehold or to the fee of the Leased Premises, Tenant shall have the right to claim and recover from the condemning authority, but not from Landlord, such compensation as may be separately awarded or recoverable by Tenant in Tenant’s own right on account of any and all damage to Tenant’s business by reason of the condemnation, and for or on account of any cost or loss to which Tenant might be put in removing Tenant’s property.

15

9.2.         Re-Entry by Landlord.  Upon such termination of the Lease or termination of Tenant’s right to use and occupy the Leased Premises as aforesaid, or if Tenant at any time during the Term vacates the Leased Premises or ceases operating said business in the entire or any appreciable part of the Leased Premises, except for causes beyond its control, Landlord may reenter the Leased Premises.

9.3.         Right to Relet.  Should Landlord elect to reenter, as herein provided, or should it take possession pursuant to legal proceedings or pursuant to any notice provided for by law, it may either terminate this Lease or it may from time to time without terminating this Lease, make such alterations and repairs as may be necessary in order to relet the Leased Premises, and relet the Leased Premises or any part thereof for such term or terms (which may be for a term extending beyond the Term) and at such rental or rentals upon such other terms and conditions as Landlord in its sole discretion may deem advisable upon each such reletting. All rentals received by the Landlord from such reletting shall be applied, first, to the payment of any indebtedness other than rent due hereunder from Tenant to Landlord; second, to the payment of any costs of such alterations and repairs; third, to the payment of rent due and unpaid future rent as the same may become due and payable hereunder. If such rentals received from such reletting during the month be less than that to be paid during that month by Tenant hereunder, Tenant shall pay any such deficiency to Landlord. Such deficiency shall be calculated and paid monthly. No such re-entry or taking possession of said Leased Premises by Landlord shall be construed as an election in its part to terminate this Lease unless a written notice of such intention be given to Tenant or unless the termination thereof be decreed by a court of competent jurisdiction. Notwithstanding any such reletting without termination, Landlord may at any time thereafter elect to terminate this Lease for such previous breach. Should Landlord at any time reenter or terminate this Lease for any breach, in addition to any other remedies it may have, it may recover from Tenant all damages it may incur by reason of such breach, including the cost of recovering the Leased Premises and reasonable attorney’s fees. All which amounts shall be immediately due and payable from Tenant to Landlord.

9.4.         Parties May Remedy Defaults.  In the event of any breach hereunder by either party, and in lieu of Landlord’s terminating this Lease as herein provided, Landlord or Tenant respectively may immediately or at any time thereafter, after having given the other party the requisite notice to correct the same and that time for such correction having elapsed, cure such breach for the account and at the expense of the other party. If Landlord or Tenant at any time, by reason of such breach, is compelled to pay, or elects to pay, any sum of money or do any act which will require the payment of any sum of money, or incurs any expense, including reasonable attorney’s fees, in instituting or prosecuting any action or proceeding to enforce such party’s rights hereunder, the sum or sums so paid or incurred by such party, if paid or incurred by Landlord, shall be deemed to be additional rent hereunder and shall be due from Tenant to Landlord on the first day of the month following the payment of such respective sums, and if paid or incurred by Tenant, shall be due and payable by Landlord on demand with interest at the rate provided in Section 4.7 hereof. This option is given to the parties is intended for their protection and its existence shall not release the parties from the obligation to perform the terms and covenants herein provided to be performed by the respective parties or deprive Landlord of any legal rights which it may have by reason of any default of Tenant.

16

9.5.         Landlord’s Remedies:  Liquidated Damages.  In the event that at any time, whether before or after the commencement of the Term hereof, a bankruptcy petition shall be filed by Tenant or against Tenant and Tenant shall thereafter be adjudicated a bankrupt, or such petition shall be approved by the court, in any court or pursuant to any statute either of the United States or of any State, whether in bankruptcy, insolvency, for reorganization under Chapter XI or XIII of the Bankruptcy Act or under any other provisions of the Bankruptcy Act, or under the provisions of any law of like impact, for the appointment of a receiver or trustee of Tenant or for the property of Tenant, or if Tenant shall make an assignment of Tenant’s property for the benefit of its creditors, or if proceedings are instituted in a court of competent jurisdiction for the reorganization, liquidation or involuntary dissolution of Tenant, then immediately upon the happening of any such event, and without any entry or other act by Landlord, this Lease and the Term and estate hereby granted (whether or not the Term shall therefore have commenced) shall expire, terminate and come to an end in the same manner and with the same force and effect as if the date of such occurrence were the date hereinbefore fixed for the expiration of the Term hereof. In the event of the termination of the Term hereof by the happening of any such event, Landlord shall forthwith upon such termination, and any other provisions of this Lease to the contrary notwithstanding, become entitled to recover as and for liquidated damages caused by such breach of the provisions of this Lease an amount equal to the difference between the then cash value of the rent reserved hereunder for the unexpired portion of the demised Term and the then cash rental value of the Leased Premises for such unexpired portion of the Term hereby demised unless the statute which governs or shall govern the proceeding in which such damages are to be provided limits or shall be entitled to prove as and for liquidated damages an amount equal to that allowed by or under such statute. The provision of this section shall be without prejudice to Landlord’s right to prove in full damages for rent accrued prior to the termination of this Lease but not paid. This provision of this Lease shall be without prejudice of any rights given Landlord by any pertinent statute to prove any amounts allowed thereby. In making such computation, the then cash rental value of the Leased Premises shall be deemed prima facie to be the rent realized upon any reletting, if such reletting can be accomplished by Landlord within a reasonable time after such a termination of this Lease.

9.6.         Expenses of Landlord.  Upon the occurrence of an event of default by Tenant, notwithstanding anything herein to the contrary and whether or not Landlord terminates this Lease, Tenant shall promptly, upon request, reimburse Landlord for all costs and expenses reasonably incurred in enforcing this Lease, including reasonable attorneys’ fees.

9.7.         Waiver of Redemption.  Tenant hereby expressly waives any and all rights of redemption granted by or under any present or future laws in the event of Tenant’s being evicted or dispossessed for any cause, or in the event of Landlord’s obtaining possession of the Leased Premises, by reason for the violation by Tenant of any of the covenants or conditions of this Lease, or otherwise.

9.8.         Defaults of Landlord.  Should Landlord be in default under the terms of this Lease, Landlord shall cure such default within thirty (30) days after written notice of such default from Tenant, or in the event such default is of such a character as to require more than thirty (30) days to cure, Landlord shall use due diligence to cure such default.

Tenant shall execute whatever instruments may be required to effect such subordination.

10.2.       Sale of Property.  Landlord shall have the right at any time to sell, transfer or convey its interest in all or any portion(s) of Landlord’s Property, improvements and buildings of which the Leased Premises are a part to any person, firm or corporation whatsoever, and upon any such sale, transfer or conveyances, Landlord shall cease to be liable under any covenant, condition or obligation imposed upon it by this Lease, or any of the terms and provisions thereof; provided, however, that any such sale, transfer or conveyance shall be subject to this Lease and that all of the Landlord’s covenants and obligations contained herein shall be binding upon the subsequent owner or owners thereof; and provided further that such transferee from Landlord shall in writing assume the obligations of Landlord hereunder.

18

as Landlord or such person or persons, firms or corporations shall deem to be necessary to preserve the walls or structures of the building from injury, and to protect the building by proper securing of foundations. Insofar as Landlord may have control over the same, all such work shall be done in a manner as will not materially interfere with the operation of Tenant’s business in the Leased Premises.

10.7.       Access to Leased Premises.  Tenant shall permit Landlord, its agents and employees, upon reasonable prior notice, to enter the Leased Premises at all reasonable times, for the purpose of making repairs, additions or alterations to the building in which the Leased Premises are located, or for the purpose of inspecting (including without limitation inspections for determining the compliance by any laboratory and animal operations with minimum health and safety requirements or standards) or for the purpose of posting notices of availability for rent without any rebate or abatement of rent and without any liability for any loss of occupation or quiet enjoyment of the Leased Premises.  For purposes of this section, the standards set forth in the Guide for the Care and Use of Laboratory Animals (which outlines the rules and regulations of the Animal Welfare Act and the Public Health Service Policy on Human Care and Use of Laboratory Animals) shall constitute such minimum standards.  In addition, upon the request of Landlord, Tenant will promptly, within ten (10) days of Landlord’s request, furnish to Landlord copies of all reports, filings and records required to be maintained by Tenant with respect to hazardous materials located or used in the Leased Premises, including all “Material Safety Data Sheets.”  The exercise by Landlord of any of its rights under this provision shall not be deemed an eviction or disturbance of Tenant’s use and possession of the Leased Premises.

10.15.     Force Majeure.  In the event that either Landlord or Tenant shall be delayed or hindered in or prevented from the performance of any act required hereunder by reason of strikes, lock outs, labor disputes, inability to procure materials, failure of power, restrictive governmental laws or regulations, riots, insurrection, war or other reason of a like nature not attributable to the negligence or fault of the party delayed in performing work or doing acts required under the terms of this Lease, then performance of such act shall be excused for the period of the unavoidable delay and the period for the performance of any such act shall be extended for an equivalent period. Provided, however, that this provision shall not operate to excuse Tenant from the timely payment of rent and other payments required by the terms of this Lease.

10.16.     General.  Nothing contained in this Lease shall be deemed or construed by the parties hereto or by any third party to create the relationship of principal and agent or of partnership or of joint venture or of any association between Landlord and Tenant, it being expressly understood and agreed that neither the method of computation of rent nor any other provisions contained in this Lease nor any acts of the parties hereto shall be deemed to create any relationship between Landlord and Tenant other than the relationship of landlord and tenant.

The consent or approval by Landlord to or of any act by Tenant requiring the Landlord’s consent or approval shall not be deemed to waive or render unnecessary Landlord’s consent or approval to or of any subsequent similar act by Tenant. The invalidity or unenforceability of any provision hereof shall not affect or impair any provision. The plural sense where there is more than one tenant and to either corporations, associations, partnership or individuals, male or females, shall in all instances be assumed as though in each case fully expressed. The laws of the State of Wisconsin shall govern the validity, performance and enforcement of this Lease. The submission of this Lease for

20

(“Broker”), and Landlord agrees that Landlord shall be solely responsible for the fees and commissions of the Brokers pursuant to separate agreement(s).  Landlord and Tenant agree to indemnify, defend and hold each other harmless against any and all claims by any other person for brokerage commissions or fees arising out of any conversation, negotiations or other dealings held by the other party with any other broker regarding this Lease.

10.18.     Landlord’s Contingency.  Notwithstanding anything to the contrary set forth herein, Landlord and Tenant hereby acknowledge and agree that (i) as of the date of this Lease, the Leased Premises are leased to EMD; and (ii) Landlord’s obligations under this Lease are contingent upon Landlord entering into a lease amendment with EMD wherein EMD agrees to release its rights with respect to the Leased Premises (the “EMD Amendment”).  In the event EMD fails to execute the EMD Amendment, Landlord shall so notify Tenant in writing, and this Lease shall automatically terminate as of the date seven (7) days after the date upon which Landlord so notifies Tenant.  Landlord and Tenant further acknowledge and agree that Landlord shall have no liability to Tenant in the event this Lease is terminated by Landlord pursuant to this Section 10.18.  Landlord shall use good faith efforts and due diligence to cause the full execution of the EMD Amendment.

10.19.  Attachments.  The following are attached hereto and made a part hereof with the same force and effect as if set forth in full herein:
