  • Commercial Lease. Start a state-specific lease for the rental of commercial property. Specify the term and rent due, as well as whether the landlord or tenant is responsible for property taxes, insurance, and maintenance and repairs.
  • Commercial Sublease. When a tenant vacates commercial property before the lease term has expired, it may be able to rent the premises to a third party. The tenant would be the sublessor and the third party would be the sublessee. Besides preparing a sublease, both parties will want to review the provisions for assignment or subletting in the original lease agreement between the landlord and the sublessor.
  • Sublease Agreement. Tenants of residential property should prepare a sublease agreement if they are seeking to sublease a room or the entire apartment or house to a third party. All parties should review the original lease agreement to see if there are any restrictions on subletting or assigning the premises.
  • Triple Net Lease. Triple net leases are a type of commercial leases where the tenant has to pay for property taxes, insurance, utilities, and maintenance, in addition to the monthly rent.
  • Office Space Lease. When renting an office space, tenants should understand the amount of the rent and duration of the lease. Other important terms include whether the space can be subleased, which parties are responsible for maintenance, and whether any furniture and furnishings will be provided.

         2.2.     Option to Purchase. Landlord hereby grants to Tenant an
         exclusive option to purchase the Premises at any time during the Term
         from and after the third anniversary of the Construction Commencement
         Date (as defined in Section 3.1 below) and in accordance with the terms
         and conditions set forth in attached EXHIBIT B (the "Option"). The
         Option shall survive the termination of this Lease for a period of one
         (1) year and may be exercised at any time during such one year period,
         provided such Lease termination occurs after the third anniversary of
         the Construction Commencement Date, and the Option shall inure to the
         benefit of the successors and assigns of Tenant. Upon Tenant's delivery
         to Landlord of written notice of Tenant's election to exercise the
         Option, Landlord shall convey the Premises to Tenant as provided in
         attached EXHIBIT B. In addition to all other rights and remedies
         provided herein, Tenant shall be entitled to the remedy of specific
         performance with regard to the Option. Notwithstanding the foregoing,
         in the event that Landlord has not, despite good faith efforts, closed
         on financing for the design, engineering, installation, equipping,
         construction and building of the Facility the gross proceeds of which
         are not less than $120,000,000 (the "Financial Closing") within
         seventy-five (75) days of the date set forth in the first paragraph of
         this Lease, this Lease shall terminate, subject to the survivability of
         provisions relating to choice of law, interpretation of the Lease,
         dispute resolution, indemnity, confidentiality and notice, and the
         parties shall have no further obligation hereunder.

         2.3.     Tenant's Right of Early Termination of Lease. Landlord and
         Tenant acknowledge that Tenant has not completed its due diligence
         review of the Premises and supporting documents. Tenant shall have the
         right to terminate this Lease in its sole and absolute discretion at
         any time within ninety (90) days of the date of execution of this
         Lease, in the event Tenant determines that the Premises are not
         suitable for development of the Facility, the exhibits to the Lease are
         not finalized, or that any of the due diligence documentation,
         including surveys and title evidence, are not complete or satisfactory
         for a transaction of this nature. Notwithstanding any of the foregoing
         to the contrary, Tenant shall have no right to terminate this Lease
         pursuant to Section 2.3 hereunder after the Financial Closing has
         occurred; provided, however, the Landlord acknowledges and agrees that
         the Financial Closing shall not take place until such time as the
         Tenant has approved the terms and conditions, except as to interest
         rate and prepayment schedule, and documentation of such financing and
         Tenant has completed to its satisfaction its due diligence review of
         the Property and approved the condition of the Property for development
         of the Facility and all documents which are exhibits to the Lease have
         been approved by Tenant. In the event Tenant exercises its right to
         terminate the Lease pursuant to this Section 2.3, the Lease shall
         terminate upon receipt by Landlord of Tenant's written notice of
         termination delivered in accordance with the notice provisions of
         Section 30 hereof, subject to survivability of provisions relating to
         choice of law, interpretation of the Lease, dispute resolution,
         indemnity, confidentiality and notice, and the parties shall have no
         further obligation hereunder.

3.       COMPLETION BY LANDLORD.

         3.1.     Construction. Landlord shall promptly commence, and shall
         pursue with due diligence and continuously until completion, the
         construction of the Facility in accordance with the provisions of the
         Construction Addendum attached hereto as EXHIBIT C, as the same may be
         amended from time to time. The date upon which Landlord commences
         construction of the Facility is referred to herein as the "Construction
         Commencement Date". Construction will be deemed to have commenced upon
         the pouring of footers for the Facility.

         3.2.     Delivery of Premises. On the Term Commencement Date, Landlord
         agrees that: (a) Landlord shall deliver possession of the Premises free
         of all leases, tenancies, occupants, construction lien claims (except
         to the extent a bond may have been posted against such claims in
         accordance with Section 14.2 below), and material defects in material
         and workmanship; (b) the Premises shall be in material compliance with
         all Applicable Laws (as defined in Section 11 below), and the
         provisions of the Construction Addendum (except as the same strictly
         relate to the Operational Qualification and Performance Qualification
         phases of Validation); (c) the Premises shall not be subject to any
         title exceptions except Permitted Encumbrances (as defined in Section
         28.1 below); and (d) Landlord shall have satisfied all those
         obligations imposed upon Landlord by the provisions of this Lease, or
         the Construction Addendum, which are required to be complied with prior
         to the Term Commencement Date.

         3.3.     Project Cost. Within one hundred twenty (120) days from and
         after the Term Commencement Date, Landlord will deliver to Tenant a
         final written certification of the Project Cost (as defined in Section
         5.2.1(b) below), specified by line item, consistent with the terms and
         requirements of this Lease and the Construction Addendum. The Project
         Cost as certified by Landlord will be subject to Tenant's reasonable
         review and approval, provided, however, that if the Project Cost does
         not exceed the preliminary estimate thereof, as detailed on attached
         EXHIBIT E with additions and subtractions as agreed to by the Tenant
         pursuant to the Construction Addendum, by more than one percent (1%),
         then Tenant will have no basis for objection thereto. Upon approval of
         the Project Cost by both Landlord and Tenant, the parties will execute
         and deliver an instrument specifying the Project Cost.

4.       USE OF PREMISES. Tenant may use the Premises for operation of a
         biopharmaceutical manufacturing facility with appurtenant offices or
         for any other lawful use; provided, however, that Tenant shall not be
         permitted to use the Premises for any use not permitted by (i)
         applicable zoning regulations, or (ii) any covenants and restrictions
         to which the Premises (with the prior written consent of Tenant) is
         made subject during the Term.

5.       RENT.

         5.1.     Basic Rent. During each year of the Term, Tenant hereby
         covenants and agrees to pay Annual Rental (as defined below) to
         Landlord, calculated in

                                       3

<PAGE>

         accordance with Section 5.2 below, in advance in twelve (12) equal
         monthly installments (each such installment being referred to herein as
         "Basic Rent"). Additionally, Tenant covenants and agrees to pay,
         directly to the taxing authority, the amount of any and all rental,
         sales or use taxes levied by any governmental body having authority
         upon the use or occupancy of the Premises. Basic Rent shall be due and
         payable beginning on the Rent Commencement Date (as defined below) and
         continuing on the first day of each and every month thereafter
         throughout the Term and shall be paid without demand, set-off or
         deduction except as otherwise provided herein to Landlord at its
         address set forth in Section 30 below. Provided, however, that if the
         Rent Commencement Date should be a date other than the first day of a
         calendar month, the Basic Rent for the first month will be prorated to
         the end of that calendar month. For purposes hereof, "Rent Commencement
         Date" shall mean the date of Substantial Completion (as defined in the
         Construction Addendum) of the Facility.

         5.2.     Basic Rent Calculation.

                  5.2.1    Definitions. For purposes of this Section 5.2.1, the
                  following terms shall have the meanings set forth below:

                           (a)      The term "Incentives" shall mean certain
                           local and state government incentives, as listed on
                           attached EXHIBIT D, paid or granted to Tenant in
                           connection with its operation in the Premises.

                           (b)      The term "Project Cost" shall mean the
                           actual, bona fide cost to Landlord with respect to
                           the acquisition, investigation, financing, design,
                           engineering, procurement, installation, construction,
                           interconnection, testing, commissioning, and
                           Validation (as defined in the Construction Addendum)
                           of the Premises, a preliminary estimate of which is
                           attached as EXHIBIT E hereto.

                  5.2.2    Rent Calculation. Annual Rental shall be calculated
                  based upon a fifteen percent (15%) capitalization rate of the
                  difference of the Project Cost less (i) the Incentives, [(ii)
                  the Tenant capital contributions (if any),] (iii) the Escrow
                  Amount (as defined in Section 31 below) and (iv) the value of
                  warrants issued by Tenant to Tiger Trust pursuant to
                  [reference to agreement]. For example, based upon an assumed
                  Project Cost of $150,137,402, Incentives in the amount of
                  $7,000,000, an Escrow Amount of $10,000,000 and the value of
                  warrants issued by Tenant of $18,750,000, the Annual Rental
                  would be $17,158,110 ($150,137,402 - $35,750,000 =
                  $114,387,402 x 0.15 = $17,158,110 and each monthly installment
                  of Basic Rent would be $1,429,833.

                  5.2.3    Annual Rent for First Two Years. Notwithstanding the
                  rent calculation illustration and other provisions in Section
                  5.2.2, the Annual

                                       4

<PAGE>

                  Rental for the first two (2) years after the Rental
                  Commencement Date shall be $13,750,000.

                  5.2.4    Additional Monetary Obligations. In addition to Basic
                  Rent, Tenant will be obligated to bear certain direct costs
                  and expenses associated with the Premises as provided in this
                  Lease (any such amounts being referred to herein as
                  "Additional Monetary Obligations"). Unless the Lease provides
                  otherwise, all Additional Monetary Obligations shall be paid
                  by Tenant to Landlord within thirty (30) days of Landlord's
                  demand for the same.

6.       TAXES AND OTHER IMPOSITIONS.

         6.1.     Tenant's Payment. As Additional Monetary Obligations
         hereunder, and except to the extent included in the Project Cost, at
         least thirty (30) days before any fine, penalty, interest or cost may
         be added thereto for the non-payment thereof (or sooner if elsewhere
         herein required), Tenant shall pay throughout the Term, unless
         otherwise set forth herein, all levies, rental, sales and use taxes,
         ad valorem property taxes, assessments, water and sewer rents and
         charges, liens, license and permit fees, charges for public utilities
         and all other charges, imposts or burdens of whatsoever kind and
         nature, general or special, foreseen or unforeseen, whether or not
         particularized by name, ordinary or extraordinary, which are
         applicable to the Term, and which are created, levied, assessed,
         confirmed, adjudged, imposed or charged by any federal, state or
         municipal government or public authority, or under any law, ordinance
         or regulation thereof, or pursuant to any Permitted Encumbrances (all
         of which are hereinafter referred to as "Impositions") upon or with
         respect to the Premises or directly upon this Lease or the Basic Rent
         payable hereunder or amounts payable by any subtenants or other
         occupants of the Premises, or upon this transaction or any related
         documents to which Tenant is a party or successor in interest, or
         against Landlord because of Landlord's estate or interest herein. If
         Tenant is permitted by the assessing and collecting authorities and
         elects to pay any Imposition in installments, Tenant shall not be
         responsible for any unpaid installments thereof which become due and
         payable after the expiration or earlier termination of the Term.
         Tenant shall pay any Imposition directly to the government or other
         public authority charged with the collection of such Imposition and
         shall furnish Landlord, not later than ten (10) days prior to the
         last day upon which they may be paid without any fine, penalty,
         interest or cost, receipts or other evidence satisfactory to Landlord
         of the payment of all such Impositions.

         6.2.     Fee in Lieu of Property Tax. Landlord will submit the
         appropriate applications and enter into the appropriate agreements to
         cause the Premises to be subject to a "Fee In Lieu of Property Tax"
         under South Carolina law; provided, however, that all such
         applications and agreements, including, without limitation, any lease
         agreement between Landlord and Sumter County, will be subject to
         Tenant's prior written approval, which will not be unreasonably
         withheld. Tenant has been advised that Landlord will apply for a Fee
         In Lieu of Property Tax at an assessment rate of ten and one-half
         percent (10.5%) (the "Assessment Rate");

                                        5

<PAGE>

         provided, however, the Assessment Rate shall be reduced to six percent
         (6%) for all investments which are (i) subject to fee in lieu of tax
         payments, (ii) invested within five (5) years of the execution of the
         original fee in lieu of tax agreement and (iii) are in excess of
         $85,000,000.00. Landlord will obtain Tenant's and any and all
         mortgagees' prior written consent before applying for a Fee In Lieu of
         Property Tax at any rate higher than the applicable Assessment Rate set
         forth above.

         6.3.     Landlord's Payment. Nothing herein contained shall be
         interpreted as requiring Tenant to pay any income, excess profits,
         corporate, capital stock, or franchise tax imposed or assessed upon
         Landlord, unless such tax or any similar tax is levied or assessed in
         lieu of all or any part of any Imposition or an increase in any
         Imposition.

         6.4.     Monthly Deposits. Notwithstanding the foregoing provisions of
         this Section 6, Landlord shall have the right upon the occurrence and
         continuance of a default by Tenant under this Lease, after giving
         effect to any applicable grace periods contained herein, at its option,
         to require Tenant to pay to Landlord or to any mortgagee, at the time
         when the monthly installment of Basic Rent is payable, an amount equal
         to one-twelfth (1/12th) of the annual Impositions as reasonably
         estimated by Landlord and, to the extent such payments are timely made,
         Landlord or such mortgagee shall be responsible for timely payment of
         such Impositions to the applicable governmental entities. If Landlord
         elects to have Tenant make such payments, Tenant also shall pay to
         Landlord or to such mortgagee, as the case may be, at least thirty (30)
         days before any fine, penalty, interest or cost may be added thereto
         for the non-payment thereof, the amount by which the Impositions
         becoming due exceed the monthly payments on account thereof previously
         made by Tenant and Landlord or such mortgagee shall be responsible for
         timely payment of such Impositions to the applicable governmental
         entities.

         6.5.     Contest by Tenant. Tenant may bring proceedings to contest the
         validity or amount of any Imposition or to recover payments therefor
         and may postpone payment to the extent allowed by applicable law,
         except with respect to the payment of the Fee in Lieu of Property Tax.
         Tenant shall save Landlord harmless from all costs and expenses in
         connection with such proceedings. Landlord shall cooperate with Tenant
         with respect to such proceedings to the extent reasonably necessary,
         but all costs, fees and expenses incurred in connection with such
         proceedings shall be borne by Tenant. Tenant shall give Landlord
         advance written notice of Tenant's intention to take any such action.

7.       INSURANCE.

         7.1.     Types. Tenant, at Tenant's sole cost and expense, shall
         maintain and keep in effect throughout the Term with policies from an
         insurer and in form and substance all reasonably satisfactory to
         Landlord the following types of insurance:

                                       6

<PAGE>

                  7.1.1    Property Insurance. Tenant will maintain insurance
                  against loss or damage to the Facility and all other
                  improvements, and the Equipment (as defined in the
                  Construction Addendum), now or hereafter located on the
                  Premises, by fire, earthquake and such other casualties as may
                  be included in the "all-risk" insurance from time to time
                  available, in an amount equal to the full insurable
                  replacement value thereof. Such policy will also include
                  business interruption coverage (including rent loss coverage)
                  in sufficient amounts. Landlord or Tenant periodically may
                  request an adjustment of the amount of the "all-risk"
                  insurance to reflect the then current full replacement cost of
                  the Facility and other improvements;

                  7.1.2    Commercial General Liability Insurance. Tenant will
                  maintain commercial general liability insurance covering
                  claims arising from bodily injury and property damage
                  occurring on, in or about the Premises with minimum limits of
                  $1,000,000 per occurrence and $2,000,000 general aggregate;

                  7.1.3    Excess Liability Insurance. Tenant will maintain
                  umbrella liability insurance with a limit of not less than
                  $10,000,000 per occurrence; and

                  7.1.4    Other Insurance. Tenant will maintain boiler
                  insurance (if applicable), plate glass insurance, and such
                  other forms of insurance as may be specified from time to time
                  by Landlord; all such insurance shall be in such reasonable
                  types and amounts as may be specified from time to time by
                  Landlord or by any mortgagee and commercially available at
                  reasonable cost.

         7.2.     Insured Parties. The policies of insurance described in
         Section 7.1 above shall name Landlord as an additional insured, and in
         addition shall contain a standard mortgagee endorsement in favor of all
         mortgagees.

         7.3.     Policies. Each policy of insurance required by Section 7.1
         above shall provide that it shall not be canceled without at least
         thirty (30) days prior written notice to Landlord and to any mortgagee
         named in any endorsement thereto. Subject to the consent of the
         insurer, each policy shall have an executive notice endorsement or
         comparable form of coverage attached thereto to the effect that no act
         or omission of Tenant shall affect the obligation of the insurer to pay
         the full amount of any loss sustained.

         7.4.     Evidence of Coverage. At least ten (10) days prior to the Term
         Commencement Date, a certificate of insurance for each policy shall be
         delivered to Landlord by Tenant. Tenant may carry any insurance
         required by this Section 7 under a blanket policy, applicable to the
         Premises, in which event Tenant shall deliver the insurer's
         certificates thereof and two certified copies of the underlying policy
         in lieu of the original, showing all of the terms of such coverage
         applicable to the Premises and showing the insured parties as
         aforesaid. If Tenant shall

                                       7

<PAGE>

         fail, refuse or neglect to obtain or to maintain any insurance that it
         is required to provide, or to furnish Landlord with satisfactory
         evidence of coverage within the time required, and Tenant shall fail to
         cure such insurance deficiency after Landlord has provided Tenant with
         five (5) days advance written notice of such insurance deficiency,
         Landlord shall have the right to purchase such insurance. All payments
         for such insurance made by Landlord shall be recoverable by Landlord
         from Tenant, together with interest thereon, as Additional Monetary
         Obligations promptly upon being billed therefor.

         7.5.     Waiver of Subrogation. Each of the parties hereto hereby
         releases the other, to the extent of the releasing party's insurance
         coverage, from any and all liability for any loss or damage covered by
         such insurance which may be inflicted upon the property of such party
         even if such loss or damage shall be brought about by the fault or
         negligence of the other party, its agents or employees. Landlord and
         Tenant shall require their respective insurance companies to include a
         standard waiver of subrogation provision in their respective policies.

8.       REPAIRS AND MAINTENANCE.

         8.1.     Tenant's Obligations. Tenant, at its sole cost and expense and
         throughout the Term, shall keep and maintain in good order and
         condition, subject to normal wear and tear, the Facility and the other
         improvements now or hereafter located upon the Premises, and any
         sidewalks, parking areas, curbs and access ways upon the Premises, and
         shall promptly make all repairs necessary to keep and maintain such
         good order and condition, whether such repairs are interior or
         exterior, ordinary or extraordinary, foreseen or unforeseen. Landlord
         shall extend to Tenant the benefit from warranties on such items, if
         any, that have been made by Landlord's contractors or vendors. Tenant
         shall keep and maintain all open areas of the Premises not built upon
         or paved as landscaped areas in a neat and orderly condition by
         performing all necessary tasks, including, but not limited to, grass
         cutting, seeding, watering, weeding and replacing any dead or diseased
         planting. Tenant shall not use or permit the use of any portion of the
         Premises for outdoor storage to the extent such use would violate
         applicable zoning ordinances or restrictive covenants. When used in
         this Section 8, the term "repairs" shall include replacements and
         renewals when necessary. All repairs made by Tenant shall utilize
         materials and equipment which are at least equal in quality and
         usefulness to those originally used in constructing the Premises.
         Tenant shall maintain and repair all HVAC systems appurtenant to the
         Facility using a service firm or firms reasonably acceptable to
         Landlord which shall provide service and maintenance in accordance with
         the manufacturer's recommendations and, upon request of Landlord, shall
         provide a copy of the contract to Landlord.

         8.2.     Landlord's Obligations. Landlord, throughout the Term and at
         Landlord's sole cost and expense, shall make all necessary repairs to
         the footings and foundations, and the structural elements of the
         Facility (including, without limitation, structural steel columns and
         girders, and the roof); provided, however, that Landlord shall have no
         responsibility to make any repair unless and until

                                       8

<PAGE>

         Landlord receives written notice of the need for such repair, and
         provided further that Landlord shall have no responsibility to repair
         any damage which arises out of or is caused by the acts or omissions of
         Tenant or any employee, agent, contractor or invitee of Tenant.

9.       UTILITY CHARGES. Tenant shall be solely responsible for and shall pay
         promptly all rents, costs and charges for water service, sewer service,
         gas, electricity, light, heat, steam, power, telephone and other
         communication services, and any and all other utilities or services
         rendered or supplied upon or in connection with the Premises.

10.      NET LEASE. Except for the obligations of Landlord expressly set forth
         herein, this Lease is a "net lease" and Landlord shall receive the
         Basic Rent as hereinabove provided as net income from the Premises, not
         diminished by any Imposition or any expenses or charges required to be
         paid to maintain the Premises or to continue the ownership of Landlord
         other than payments contemplated under Section 6.3 or under any
         mortgages now existing or hereafter created by Landlord, and, except as
         set forth herein, Landlord is not and shall not be required, to render
         any services of any kind to Tenant.

11.      GOVERNMENTAL REGULATIONS. Landlord covenants and agrees that it shall
         deliver the Premises to Tenant in a condition such that the Premises
         comply with all Applicable Laws (as defined below). With regard to all
         or any part of the Premises or to the use or manner of use of the
         Premises, or to the sidewalks, parking areas, curbs and access ways
         within the Premises, or to the fixtures and equipment in the Premises,
         throughout the Term and at its sole cost and expense, Tenant shall: (i)
         comply promptly with all Applicable Laws relating to Tenant's business
         and Tenant's obligations under this Lease; (ii) keep in force at all
         times all licenses, consents and permits necessary for the lawful use
         of the Premises for the purposes herein provided; and (iii) comply with
         the requirements of all public liability, fire, and other policies of
         insurance covering the Premises. Provided, however, that Tenant shall

         footings and foundations and the structural elements of the Facility
         (including, without limitation, structural steel columns and girders,
         and the roof), unless the need for such compliance arises out of or is
         caused by the acts or omissions of Tenant or any employee, agent,
         contractor or invitee of Tenant. For purposes hereof, "Applicable Laws"
         shall mean all legal requirements, laws, ordinances, orders, rules or
         regulations, permit conditions and requirements of all federal, state,
         county and municipal governments, courts, departments, commissions,
         boards and offices, or any other body exercising functions similar to
         any of those of the foregoing, which may be applicable to the Premises
         or any part thereof.

12.      SIGNS. Except for signs which are located wholly within the interior of
         the Facility and which are not visible from the exterior of the
         Premises, no signs shall be placed, erected, maintained or painted at
         any place upon the Premises without the prior written consent of
         Landlord as to the size, design, color, location, content,
         illumination, composition or material and mobility thereof, which

                                       9

<PAGE>

         consents shall not be unreasonably withheld, conditioned or delayed;
         provided, upon consent of the architectural review committee to the
         same, as required pursuant to certain Permitted Encumbrances, Landlord
         hereby consents to the sign(s) detailed in the Review Plans and
         Specifications attached to the Construction Addendum. All signs shall
         be maintained by Tenant in good condition during the Term, and Tenant
         shall remove all signs at the termination of this Lease and shall
         repair and restore any damage caused by the installation or removal
         thereof.

13.      ALTERATIONS, ADDITIONS AND FIXTURES.

         13.1.    Installation of Fixtures. Subject to the provisions of Section
         14, Tenant shall have the right to install in the Facility any trade
         fixtures from time to time during the Term; provided, however, that no
         such installation or removal thereof shall compromise the structural
         portions of the Facility and Tenant shall repair and restore any damage
         or injury to the Premises caused thereby.

         13.2.    Tenant's Alterations. Except as otherwise set forth herein,
         Tenant shall not make or permit to be made any material alterations,
         improvements or additions to the Premises without on each occasion
         first presenting to Landlord plans and specifications therefor and
         obtaining Landlord's prior written consent thereto, which consent shall
         not be unreasonably withheld or delayed; except that Tenant may make
         alterations, improvements or additions to those portions of the
         Premises that Landlord is not obligated to maintain pursuant to Section
         8.2 above, without the consent of Landlord, provided that: (i) Tenant
         supplies Landlord with plans and specifications and any necessary
         permits therefor at least ten (10) days in advance of commencing
         construction thereof; (ii) such alterations and improvements do not
         impair the structural strength of the Facility or any other
         improvements or reduce the value of the Premises; and (iii) Tenant
         shall take or cause to be taken all steps that are required by Section
         14 hereof and that are required or permitted by law in order to avoid
         the imposition of any mechanic's lien upon the Premises. Any and all
         alterations, improvements and additions to the Premises which are
         constructed, installed or otherwise made by Tenant shall be the
         property of Tenant until the expiration or earlier termination of this
         Lease. Subject to Tenant's exercise of and rights under the Option,
         upon the expiration or earlier termination of this Lease, all
         alterations and additions shall remain on the Premises and become the
         property of Landlord without payment therefor by Landlord unless, upon
         the expiration or earlier termination of this Lease, Landlord shall
         give written notice to Tenant to remove the same; in which event Tenant
         will remove such alterations, improvements and additions, and repair
         and restore any damage to the Premises caused by the installation or
         removal thereof. Prior to the completion of any material alteration,
         improvement or addition, Landlord and Tenant agree to execute a written
         statement as to whether or not the alteration, improvement or addition
         shall be required to be removed upon the expiration or earlier
         termination of this Lease.

14.      MECHANICS' LIENS.

         14.1.    Tenant's Obligations. Tenant shall promptly pay any
         contractors and materialmen engaged by Tenant to supply labor, work or
         materials at the Premises so as to minimize the possibility of a lien
         attaching to the Premises. Tenant shall take all reasonable steps
         permitted by law in order to avoid the imposition of any such
         mechanic's lien upon the Premises relating to work contracted for by
         Tenant. Should any such lien be filed, for work performed for Tenant
         other than by Landlord, Tenant shall bond against or discharge the same
         within thirty (30) days after the lien is filed and served on Tenant,
         as provided in Section 29-5-110 of the South Carolina Code of Laws of
         1976, as amended. Nothing in this Lease is intended to authorize Tenant
         to do or cause any work or labor to be done or any materials to be
         supplied for the account of Landlord, all of the same to be solely for
         Tenant's account and at Tenant's risk and expense. Throughout this
         Lease the term "mechanic's lien" is used to include any lien,
         encumbrance or charge levied or imposed upon the Premises or any
         interest therein or income therefrom on account of any mechanic's,
         laborer's or materialmen's lien or arising out of any debt or liability
         to or any claim or demand of any contractor, mechanic, supplier,
         materialmen or laborer and shall include without limitation any
         injunctive or equitable action brought by any person entitled to any
         mechanic's lien.

         14.2.    Landlord's Obligations. Landlord shall promptly pay any
         contractors and materialmen who supply labor, work or materials on
         Landlord's behalf, or at Landlord's direction, at the Premises so as to
         minimize the possibility of a lien attaching to the Premises. Landlord
         shall take all reasonable steps permitted by law in order to avoid the
         imposition of any such mechanic's lien upon the Premises relating to
         work performed on Landlord's behalf or at the direction of Landlord
         pursuant to the terms of this Lease or the Construction Addendum.
         Should any such lien be filed, Landlord shall bond against or discharge
         the same within thirty (30) days after the lien is filed and served on
         Landlord, as provided in Section 29-5-110 of the South Carolina Code of
         Laws of 1976, as amended.

15.      LANDLORD'S RIGHT OF ENTRY.

         15.1.    Landlord's Access. Subject to the provisions of Section 15.2
         below, Tenant shall permit Landlord and the authorized representatives
         of Landlord and of any mortgagee to enter the Premises for the purpose
         of (i) inspecting the Premises, or (ii) making any necessary repairs
         thereto and performing any work therein pursuant to the terms of this
         Lease.

         15.2.    Conditions to Landlord's Access. Landlord's right of entry to
         the Premises, as set forth in Section 15.1 above, is subject to the
         following conditions:

                           (a)      Landlord shall provide to Tenant at least
                           twenty-four (24) hours prior written notice of any
                           proposed entry by Landlord and/or its authorized
                           representatives into the Premises. Such notice shall
                           specify the type of inspection and/or repairs to be
                           performed by

                                       11

<PAGE>

                           Landlord and/or its authorized representatives in the
                           Premises, and, to the extent that the same may have
                           any effect upon Tenant's manufacturing operations in
                           the Premises, such inspection and/or repairs shall be
                           scheduled at a time mutually agreeable to the
                           parties;

                           (b)      Landlord and its authorized representatives,
                           and any persons accompanying any of them into the
                           Premises, shall be accompanied at all times by a
                           representative of Tenant;

                           (c)      Any entry into the Premises by Landlord and
                           its authorized representatives, and any persons
                           accompanying any of them, shall be in strict
                           compliance with all security procedures, and with all
                           standard operating procedures required by good
                           manufacturing practice, as enacted by Tenant from
                           time to time;

                           (d)      Prior to making any repairs or commencing
                           any construction in the Premises, Landlord shall
                           provide to Tenant evidence of such types of
                           insurance, and in such amounts, as may be reasonably
                           specified by Tenant; and

                           (e)      No inspection or repairs undertaken by
                           Landlord in the Premises shall unreasonably interfere
                           with the operation of the Premises or the conduct of
                           Tenant's business therein.

16.      DAMAGE BY FIRE OR OTHER CASUALTY.

         16.1.    Tenant shall promptly notify Landlord if the Premises shall be
         damaged or destroyed by fire or other casualty. Except during the final
         five (5) years of the Term, Landlord, subject to the conditions set
         forth in this Section 16, shall repair, rebuild or replace such damage
         and restore the Premises to substantially the same condition in which
         they were immediately prior to such damage or destruction. During the
         final five (5) years of the Term, Landlord shall have the option to not
         repair the Premises. If Landlord elects not to repair the Premises
         during the final five (5) years of the Term, then Landlord shall
         provide written notice of its election to Tenant with fifteen (15) days
         of the occurrence of such fire or other casualty. In such event, Tenant
         may, within fifteen (15) days of its receipt of Landlord's written
         election, either (i) terminate this Lease; or (ii) elect to exercise
         its Option pursuant to Section 2.2 and the insurance proceeds payable
         as a result of the damage or destruction shall first be applied to the
         Option Purchase Price, as calculated in accordance with the terms set
         forth in attached EXHIBIT B, with any remaining proceeds being
         distributed to Tenant.

         16.2.    Subject to Section 16.1 above, within thirty (30) days of the
         occurrence of a fire or other casualty, Landlord shall deliver to
         Tenant a notice (the "Casualty Notice") setting forth the time that
         Landlord estimates will be necessary to repair the Premises from the
         earlier of commencement of the reconstruction or repair or the date of
         Landlord's receipt of the net insurance proceeds (the "Probable

                                       12

<PAGE>

         Restoration Period"). In the event that the notice specifies a Probable
         Restoration Period longer than one hundred eighty (180) days, exclusive
         of the time necessary to perform Validation, then Tenant shall have the
         option, to be exercised within ten (10) days of its receipt of the
         Casualty Notice, to terminate this Lease. If Landlord and Tenant shall
         disagree as to the Probable Restoration Period, then such period shall
         be determined by a qualified independent general contractor reasonably
         acceptable to both parties, and, upon receipt by Tenant of notice of
         the Probable Restoration Period, as determined by such general
         contractor, Tenant shall have ten (10) days within which to exercise
         its option to terminate this Lease, if applicable.

         16.3.    Landlord's work shall be commenced promptly upon Landlord's
         receipt of the insurance proceeds, and shall be completed with due
         diligence, subject to Excusable Delay (as defined in the Construction
         Addendum) within the Probable Restoration Period. Landlord shall
         proceed in good faith and with due diligence to effect a settlement
         with the insurance company and to procure the insurance proceeds.
         Notwithstanding anything in this Section 16 to the contrary, if
         Landlord (i) has not effected a settlement with the insurance company
         and procured the insurance proceeds within sixty (60) days from and
         after the occurrence of such fire or other casualty, (ii) has failed
         during such sixty (60) day period or thereafter fails to proceed in
         good faith and with due diligence to effect a settlement and (iii)
         fails to diligently prosecute the work, Tenant may terminate this Lease
         by written notice to Landlord. Furthermore, if Landlord fails to
         complete Landlord's work within the Probable Restoration Period, then
         Tenant shall have the option, to be exercised within ten (10) days
         following the end of the Probable Restoration Period, to terminate this
         Lease by written notice to Landlord.

         16.4.    The net amount of any insurance proceeds (excluding proceeds
         received pursuant to any rental coverage endorsement) recovered by
         reason of the damage or destruction of the Premises in excess of the
         reasonable cost of adjusting the insurance claim and collecting the
         insurance proceeds (such excess amount being hereinafter called the
         "net insurance proceeds") shall be applied towards the cost of
         restoration and sums held by Landlord for that purpose shall be
         maintained in a segregated account. If in Landlord's reasonable
         judgment the net insurance proceeds will not be adequate to complete
         such restoration, then upon Landlord's written request, Tenant shall
         pay out of funds other than such net insurance proceeds, the amount by
         which the cost of restoration estimated by Landlord will exceed the net
         insurance proceeds, such sum payable by Tenant to be later readjusted
         to such actual excess promptly upon the completion of restoration. If
         such net insurance proceeds are more than adequate, the amount by which
         such net insurance proceeds exceed the cost of restoration will be
         retained by Landlord or applied to repayment of any mortgage secured by
         the Premises.

         16.5.    Landlord's obligation or election to restore the Premises
         under this Section 16 shall not include the repair, restoration or
         replacement of the fixtures, equipment, improvements, alterations,
         furniture or any other property owned, installed, made by, or in the
         possession of Tenant; provided, however, that

                                       13

<PAGE>

         Landlord's obligation or election to restore the Premises shall include
         the repair, restoration or replacement of the Equipment (as defined in
         the Construction Addendum).

         16.6.    Commencing with the date of any damage to the Premises, the
         Basic Rent provided for in this Lease shall abate proportionally, to
         the extent that and for so long as, any portion of the Premises is not
         reasonably usable with reasonable ingress and egress and its
         proportionate number of required parking spaces, and is not actually
         used, by Tenant in the ordinary conduct of its business. In calculating
         the foregoing abatement of Basic Rent, the parties agree that, to the
         extent that any portion of the Premises utilized for Tenant's
         manufacturing operations is not reasonably usable as a result of such
         damage, all portions of the Premises utilized for Tenant's
         manufacturing operations will be considered not reasonably usable for
         purposes hereof.

17.      NO ABATEMENT OF RENT. Except as otherwise set forth herein, there shall
         be no abatement or reduction of the Basic Rent, the Additional Monetary
         Obligations or other sums payable hereunder for any cause whatsoever,
         and this Lease shall not terminate, and Tenant shall not be entitled to
         surrender the Premises.

18.      INDEMNIFICATION OF LANDLORD AND TENANT.

         18.1.    Tenant's Obligations. Tenant indemnifies and agrees to save
         Landlord harmless from and against any and all claims, actions,
         damages, liability and expense (including without limitation reasonable
         fees of attorneys, investigators and experts) in connection with loss
         of life, personal injury or damage to property caused to any person in
         or about the Premises arising from the acts or omissions of Tenant, its
         agents, contractors, employees, licensees or invitees; unless such
         loss, injury or damage occurs as a proximate result of (i) the acts or
         omissions of Landlord, its agents, contractors, employees, licensees or
         invitees, or (ii) the structural or mechanical failure of the Premises
         due to an inherent defect or failure to maintain (to the extent that
         Landlord is required to maintain the same pursuant to the terms of
         Section 8.2 hereof). Without limiting the foregoing, Tenant will
         forever release and hold Landlord harmless from all claims arising out
         of damage to Tenant's property unless such damage occurs as a proximate
         result of (i) the acts or omissions of Landlord, its agents, employees,
         licensees or invitees, or (ii) the structural or mechanical failure of
         the Premises due to an inherent defect or failure to maintain (to the
         extent that Landlord is required to maintain the same pursuant to the
         terms of Section 8.2 hereof). In case any such claim, action or
         proceeding is brought against Landlord, upon notice from Landlord and
         at Tenant's sole cost and expense, Tenant shall resist or defend such
         claim, action or proceeding or shall cause it to be resisted or
         defended by an insurer.

         18.2.    Landlord's Obligations. Landlord indemnifies and agrees to
         save Tenant harmless from and against any and all claims, actions,
         damages, liability and expense (including without limitation reasonable
         fees of attorneys, investigators

                                       14

<PAGE>

         and experts) in connection with loss of life, personal injury or damage
         to property arising from (i) the acts or omissions of Landlord, its
         agents, contractors, employees, licensees or invitees, or (ii) the
         structural or mechanical failure of the Premises due to an inherent
         defect or failure to maintain (to the extent that Landlord is required
         to maintain the same pursuant to the terms of Section 8.2 hereof),
         except to the extent such loss, injury or damage occurs as a proximate
         result of the acts or omissions of Tenant, its agents, employees,
         licensees or invitees. In case any such claim, action or proceeding is
         brought against Tenant, upon notice from Tenant and at Landlord's sole
         cost and expense, Landlord shall resist or defend such claim, action or
         proceeding or shall cause it to be resisted or defended by an insurer.

         18.3.    Environmental Indemnity. Tenant agrees that during the Term,
         neither Tenant nor any of Tenant's agents, employees, contractors,
         invitees, assignees, or sublessees shall cause any hazardous material
         to be brought on, kept, or used in, on or about the Premises, or
         transported to or from the Premises except for hazardous material that
         is necessary or useful to Tenant's business, which shall at all times
         be used, kept, stored, and disposed of in a manner that fully complies
         with all Applicable Laws and all policies of any fire insurance
         underwriter relating to any such hazardous material.

                  If Tenant breaches any of its obligations contained in this
         Section 18.3, or if any act or omission of Tenant or any of its agents,
         employees, contractors, invitees, assignees, or sublessees causes any
         hazardous material to be discharged or released from, on, or in the
         Premises, then Tenant shall indemnify Landlord against and hold
         Landlord harmless from, any and all claims, judgments, damages,
         penalties, fines, costs, liabilities, losses, and expenses (including,
         but not limited to, reasonable attorney fees, consultant fees, and
         expert fees) arising during or after the Term as a result of that
         breach or that discharge or release. This indemnification includes, but
         is not limited to, costs incurred in connection with the investigation
         of site conditions or any cleanup, repair, removal, or detoxification
         work required by any federal, state, or local governmental agency or
         political subdivision. Without limiting the above, if the presence of
         any hazardous material in or on the Premises caused by Tenant or any of
         Tenant's agents, employees, contractors, invitees, assignees, or
         sublessees results in any discharge or release of hazardous material
         from, in, or on the Premises, Tenant shall promptly take all action, at
         its sole expense, as necessary or appropriate to meet the requirements
         of regulatory agencies including, but not limited to, all site
         assessment and remediation required by federal, state or local
         regulatory agencies.

19.      CONDEMNATION.

         19.1.    Landlord's Termination. (i) If fifty percent (50%) or more of
         the Premises are taken by eminent domain or condemnation or any
         transfer in lieu of condemnation; or (ii) subject to the provisions
         of Section 19.3.1 below, if any of the Premises is taken by eminent
         domain or condemnation or any transfer in lieu of condemnation and,
         in Landlord's reasonable opinion, it would be impractical,

                                       15

<PAGE>

         or the condemnation proceeds are insufficient to restore the remainder
         of the Premises; then, in any such event, at Landlord's option, this
         Lease shall terminate and all obligations hereunder shall cease as of
         the date upon which possession is taken by the condemnor and the Basic
         Rent and the Additional Monetary Obligations herein reserved shall be
         apportioned and paid in full by Tenant to Landlord to that date and all
         Basic Rent and Additional Monetary Obligations prepaid for periods
         beyond that date shall forthwith be repaid by Landlord to Tenant.

         19.2.    Tenant's Termination. In addition to the foregoing, (i) if
         fifty percent (50%) or more of the Premises or fifty percent (50%) or
         more of the floor area of the Facility are taken by eminent domain or
         condemnation or any transfer in lieu of condemnation, or (ii) if less
         than fifty percent (50%) of the Premises are taken by eminent domain or
         condemnation or any transfer in lieu of condemnation and, in the good
         faith judgment of Tenant, the remaining portion of the Premises cannot
         be economically and practically used by Tenant for the conduct of its
         business; or (iii) if less than fifty percent (50%) of the Premises are
         taken by eminent domain or condemnation or any transfer in lieu of
         condemnation and such condemnation prevents or effectively prevents
         access to the Premises or the entrances of the Facility, or has a
         material adverse effect upon the number of parking spaces reasonably
         available to Tenant or the providing of other essential services of the
         Premises, unless Landlord shall have provided reasonable substitutes
         therefor; then, in any such event, Tenant shall have the right upon
         written notice to Landlord to terminate this Lease. In the event of
         such a termination, then, this Lease shall terminate and all
         obligations hereunder shall cease as of the date upon which possession
         is taken by the condemnor and the Basic Rent and the Additional
         Monetary Obligations herein reserved shall be apportioned and paid in
         full by Tenant to Landlord to that date and all Basic Rent and
         Additional Monetary Obligations prepaid for periods beyond that date
         shall forthwith be repaid by Landlord to Tenant.

         19.3.    Partial Condemnation.

                  19.3.1   If there is a partial condemnation or transfer in
                  lieu of condemnation and Landlord decides to terminate
                  pursuant to Section 19.1 hereof, then, except during the last
                  five (5) years of the Term, Tenant may require Landlord to
                  withdraw its notice of termination by: (i) giving Landlord
                  written notice thereof within ten (10) days from and after its
                  receipt of Landlord's notice to Tenant of Landlord's intention
                  to terminate, (ii) agreeing to pay the cost of restoration in
                  excess of the condemnation proceeds reduced by those sums
                  reasonably expended by Landlord in collecting the condemnation
                  proceeds, and (iii) giving Landlord adequate security for such
                  payment within such ten (10) day period. During the final five
                  (5) years of the Term, Tenant may require Landlord to withdraw
                  its notice of termination by giving written notice of Tenant's
                  election to exercise the Option with ten (10) days from and
                  after its receipt of Landlord's notice to Tenant of Landlord's
                  intention to terminate. In such event, the condemnation
                  proceeds shall first be applied to the Option

                                       16

<PAGE>

                  Purchase Price, as calculated in accordance with the terms set
                  forth in attached EXHIBIT B, with any remaining proceeds being
                  distributed to Tenant.

                  19.3.2   If there is a partial condemnation or transfer in
                  lieu of condemnation and this Lease has not been terminated
                  pursuant to Section 19.1 or Section 19.2 hereof, Landlord
                  shall restore the Facility and the improvements which are part
                  of the Premises to a condition and size as nearly comparable
                  as reasonably possible to the condition and size thereof
                  immediately prior to the date upon which possession shall have
                  been taken by the condemnor. Except as otherwise set forth
                  herein, if the condemnation proceeds are more than adequate to
                  cover the cost of restoration and Landlord's reasonable
                  expenses in collecting the condemnation proceeds, any excess
                  proceeds shall be retained by Landlord or applied to repayment
                  of any mortgage secured by the Premises.

                  19.3.3   If there is a partial condemnation and neither
                  Landlord nor Tenant has exercised its right to terminate on
                  the date upon which the condemnor shall have obtained
                  possession, the obligations of Landlord and Tenant under the
                  Lease shall be unaffected by such condemnation except that the
                  Basic Rent and the Additional Monetary Obligations provided
                  for herein shall abate proportionately to the extent that any
                  portion of the Premises is not reasonably useable by Tenant in
                  the conduct of its business. In the event that the parties are
                  unable to agree upon the amount of such abatement, either
                  party may submit the issue to arbitration.

         19.4.    Award.   In the event of a condemnation or transfer in lieu of
         condemnation, Tenant shall have the right to make a claim against the
         condemnor and/or share in an award of proceeds for (i) removal
         expenses, business dislocation damages and moving expenses, (ii) costs
         incurred and paid by Tenant in connection with any alteration or
         improvement made by Tenant to the Premises, (iii) the value of any of
         Tenant's property taken, and (iv) any other separate claim which Tenant
         may be permitted to make, provided such other separate claim under this
         item (iv) shall not reduce or adversely affect the amount of Landlord's
         award.

         19.5.    Temporary Taking. If the condemnor should take only the right
         to possession for a fixed period of time or for the duration of an
         emergency or other temporary condition, then, notwithstanding anything
         hereinabove provided, this Lease shall continue in full force and
         effect without any abatement of Basic Rent or any Additional Monetary
         Obligations, and the amounts payable by the condemnor with respect to
         any period of time prior to the expiration or earlier termination of
         this Lease shall be paid by the condemnor to Tenant as compensation for
         the condemnation of Tenant's business operations in the Premises.

                                       17

<PAGE>

         19.6.    Settlement. Landlord and Tenant, jointly, shall approve and be
         a party to all condemnation and eminent domain proceedings or any
         transfer in lieu thereof. Any settlement shall be approved by both
         Landlord and Tenant.

20.      QUIET ENJOYMENT. Tenant, upon paying the Basic Rent, and the Additional
         Monetary Obligations and the other charges herein provided for, and
         observing and keeping all covenants, agreements and conditions of this
         Lease on its part to be kept, shall quietly have and enjoy the Premises
         during the Term without hindrance or molestation by anyone claiming by
         or through Landlord, and, except as otherwise provided in the Fee in
         Lieu of Tax Agreement with Sumter County, South Carolina or in Section
         15 hereof, no person or entity claiming by or through Landlord shall
         take any action that interferes with Tenant's peaceful and quiet
         enjoyment and possession of the Premises, subject, however, to the
         Permitted Encumbrances.

21.      ASSIGNMENT AND SUBLETTING.

         21.1.    Tenant's Right to Assign and Sublet. Tenant may not assign,
         mortgage, pledge or encumber this Lease, or sublet the whole or any
         part of the Premises, without the prior written consent of Landlord,
         which consent will not be unreasonably withheld. Notwithstanding the
         foregoing to the contrary, Tenant shall have the right, without
         Landlord's consent, at any time and from time to time, to assign this
         Lease, or sublet all or any part of the Premises to: (i) an Affiliate
         of Tenant; (ii) any entity rated BBB or better by Moody's investment
         services; or (iii) any person or entity for the operation of dining,
         daycare, fitness and similar facilities for use by Tenant's employees.
         For purposes of this Section 21.1, the term "Affiliate" means a person
         or entity which (either directly or indirectly, through one or more
         intermediaries) controls, is in common control with or is controlled
         by, another person or entity. For purposes of this definition, the term
         "control" means (a) legal or beneficial ownership of more than fifty
         percent (50%) of the voting interests of an entity, or (b) the
         possession, directly or indirectly, of the power to direct or cause the
         direction of the management or policies of a person or entity, whether
         through the ownership of voting securities, by contract or otherwise.

         21.2.    Waiver of Lien. Contemporaneous with the full execution of
         this Lease, Landlord agrees to use best efforts to obtain the consent
         and acknowledgement by Landlord's mortgagee for execution by Landlord
         of a waiver, in form and substance reasonably acceptable to the
         parties, Landlord's mortgagee and their respective counsel, of any lien
         in favor of Landlord with respect to Tenant's FF&E (as defined in the
         Construction Addendum) located on the Premises.

22.      SECURITY AGREEMENT. The obligations of the Tenant pursuant to this
         Lease, including but not limited to the payment of rent, shall be
         secured by a pledge of the intellectual property right of the Tenant
         pursuant to the Security Agreement, a form of which is attached hereto
         as EXHIBIT M.

                                       18

<PAGE>

23.      SUBORDINATION. This Lease and Tenant's rights hereunder shall be
         subject and subordinate at all times in lien and priority to any first
         mortgage or other primary encumbrance now or hereafter placed upon or
         affecting the Premises, and to any second mortgage or encumbrance with
         the consent of the first mortgagee, and to all renewals, modifications,
         consolidations and extensions thereof, without the necessity of any
         further instrument or act on the part of Tenant; provided, however,
         that such subordination shall be subject to Tenant's right not to have
         its rights under this Lease disturbed so long as Tenant shall not be in
         default with respect to any of its obligations under this Lease beyond
         any applicable cure period provided for herein, and shall be subject
         further to Landlord not making Tenant a party to any proceeding to
         foreclose any such mortgage unless required by law. Tenant's
         subordination and right not to be disturbed shall be memorialized in a
         commercially reasonable subordination and non-disturbance agreement in
         form and substance reasonably acceptable to Landlord's mortgagee and
         Tenant and their respective counsel. Tenant shall execute and deliver,
         within fifteen (15) days of receipt of Landlord's demand therefor, any
         further instrument or instruments confirming the subordination of this
         Lease to the lien of any such first mortgage or to the lien of any
         other mortgage if requested to so do by Landlord with the consent of
         the first mortgagee, and any further instrument or instruments of
         attornment, consistent with the terms of this Lease and Tenant's rights
         hereunder, that may be desired by any such mortgagee or Landlord.
         Notwithstanding the foregoing, any mortgagee may at any time
         subordinate its mortgage to this Lease, without Tenant's consent, by
         giving notice in writing to Tenant, and thereupon this Lease shall be
         deemed prior to such mortgage without regard to their respective dates
         of execution and delivery, and in that event such mortgagee shall have
         the same rights with respect to this Lease as though this Lease had
         been executed prior to the execution and delivery of the mortgage and
         had been assigned to such mortgagee. In addition to the foregoing,
         Tenant agrees to deliver, for the benefit of Landlord's construction
         lender, a Nondisturbance, Attornment and Subordination Agreement in
         substantially the form attached hereto as EXHIBIT F.

24.      MEMORANDUM OF LEASE; ESTOPPEL CERTIFICATES.

         24.1.    Memorandum of Lease. Tenant and Landlord, at any time and from
         time to time and within ten (10) days after Landlord's or Tenant's, as
         the case may be, written request, shall execute, acknowledge and
         deliver to Landlord or Tenant, as the case may be, a short form or
         memorandum of this Lease for recording purposes. Landlord and Tenant
         agree to use the form of Memorandum of Lease attached hereto as EXHIBIT
         G.

         24.2.    Estoppel Certificates. Tenant or Landlord, at any time and
         from time to time and within fifteen (15) days after written request
         from the other, shall execute, acknowledge and deliver to Landlord or
         Tenant, as the case may be, a written instrument (in the form attached
         hereto as EXHIBIT H or such other form as either party may reasonably
         request) in recordable form certifying, as applicable, that this Lease
         is unmodified and in full force and effect (or, if there have been
         modifications, that it is in full force and effect as modified and
         stating

                                       19

<PAGE>

         the modifications); stating that the improvements required by Section 3
         hereof have been Substantially Completed (as defined in the
         Construction Addendum); certifying that Tenant has accepted possession
         of the Premises; stating the Term Commencement Date and the dates to
         which Basic Rent, Additional Monetary Obligations and other charges
         have been paid in advance, if any; stating that to the best knowledge
         of the signer of such instrument Landlord or Tenant, as the case may
         be, is not in default of this Lease; stating any other fact or
         certifying any other condition reasonably requested by Landlord or
         Tenant, as the case may be, or reasonably required by any mortgagee or
         prospective mortgagee or purchaser of the Premises or any interest
         therein; and stating that it is understood that such instrument may be
         relied upon by any mortgagee or prospective mortgagee or purchaser of
         the Premises or any interest therein or by any assignee of Landlord's
         or Tenant's interest in this Lease or by any assignee of any mortgagee.
         The foregoing instrument shall be addressed to Landlord or Tenant, as
         the case may be, and to any mortgagee, prospective mortgagee, purchaser
         or other party specified by Landlord or Tenant, as the case may be. In
         addition to the foregoing, Tenant agrees to deliver, for the benefit of
         Landlord's construction lender, the following documents: (i) a
         pre-construction estoppel in substantially the form attached hereto as
         EXHIBIT I; and (ii) a post-construction estoppel in substantially the
         form attached hereto as EXHIBIT J.

25.      CURING DEFAULTS. If Tenant or Landlord shall be in default in the
         performance of any of their respective obligations hereunder, the
         non-defaulting party, without any obligation to do so, in addition to
         any other rights it may have in law or equity, and giving effect to
         applicable grace periods, may elect to cure such default on behalf of
         the defaulting party after written notice (except in the case of
         Emergency) to the defaulting party. The defaulting party shall
         reimburse the non-defaulting party upon demand for any sums paid or
         costs incurred by the non-defaulting party in curing such default,
         including interest thereon from the respective dates of the
         non-defaulting party's making the payments and incurring such costs,
         which sums and costs together with interest thereon shall be payable
         promptly upon being billed therefor. In the event of a Tenant default,
         such sums together with interest thereon shall be deemed Additional
         Monetary Obligations. For purposes hereof, "Emergency" means fire,
         release of hazardous substances, explosion, severe weather, hazardous
         situations necessitating the extraction of personnel, any condition
         which a party reasonably believes poses an eminent threat of bodily
         injury, death, environmental or substantial property damage, or other
         similar incidents.

26.      SURRENDER.

         26.1.    Condition Upon Termination. Subject to the terms of Sections
         13.2, 16, and 19 hereof, upon the expiration or earlier termination of
         the Term, Tenant shall promptly yield up, clean and neat, and in the
         same condition, order and repair in which they are required to be kept
         throughout the Term, the Premises and all improvements, alterations and
         additions thereto, ordinary wear and tear (and damages from fire or
         casualty not required to be repaired by Tenant hereunder) excepted.

         26.2.    Holding Over. If Tenant, or any person claiming through
         Tenant, shall continue to occupy the Premises after the expiration or
         earlier termination of the Term, such occupancy shall be deemed to be
         under a month-to-month tenancy under the same terms and conditions set
         forth in this Lease except that such month-to-month tenancy may be
         terminated by either party upon thirty (30) days written notice to the
         other. Anything to the contrary notwithstanding, any holding over by
         Tenant without Landlord's prior written consent shall constitute a
         default hereunder and shall be subject to all the remedies set forth in
         Section 27 hereof.

27.      DEFAULTS; REMEDIES.

         27.1.    Defaults by Tenant. It shall be an event of default if any of
         the following listed conditions occur. Landlord shall give Tenant
         written notice specifying in what manner Tenant has defaulted and such
         notice shall commence the tolling of any grace period provided in
         Section 27.5 hereof:

                           (a)      If Tenant does not pay in full when due and
                           without demand any and all installments of Basic Rent
                           or Additional Monetary Obligations or any other
                           charges or payments required by this Lease; or

                           (b)      If Tenant violates or fails to perform or
                           otherwise breaches any material agreement, term,
                           covenant or condition herein contained, or

                           (c)      If Tenant becomes insolvent or bankrupt or
                           makes an assignment for the benefit of creditors or
                           if a petition in bankruptcy or for reorganization or
                           for an arrangement with creditors under any federal
                           or state law is filed by or against Tenant, or a bill
                           in equity or other proceeding for the appointment of
                           a receiver, trustee, liquidator, custodian,
                           conservator or similar official for any of Tenant's
                           assets is commenced, or if any of the real or
                           personal property of Tenant shall be levied upon by
                           any sheriff, marshal or constable, provided, however,
                           that any proceeding brought by anyone other than the
                           parties to this Lease under any bankruptcy,
                           reorganization arrangement, insolvency, readjustment,
                           receivership or similar law shall not constitute a
                           default unless such proceeding has continued for more
                           than thirty (30) consecutive days.

         27.2.    Landlord's Remedies Upon Tenant's Default. Subject to the
         provisions of Section 27.5 below, in the event of any default hereunder
         by Tenant, Landlord shall have the following rights:

                  27.2.1   To charge a late payment penalty of four percent (4%)
                  of any amount owed to Landlord pursuant to this Lease which is
                  not paid within ten (10) days of the date which is set forth
                  in the Lease if a date is specified, or, if a date is not
                  specified, within thirty (30) days of the receipt by Tenant of
                  a bill therefor from Landlord. If Landlord incurs a penalty in
                  connection with any payment which Tenant has failed to make
                  within the times required in this Lease, and Landlord has
                  timely requested such payment from Tenant, Tenant shall pay
                  Landlord, in addition to such sums, the full amount of such
                  penalty incurred by Landlord.

                  27.2.2   To accelerate the whole or any part of the Basic Rent
                  for the lesser of the entire unexpired balance of the Term or
                  a period of eighteen (18) months, reduced to present value,
                  and any Basic Rent if so accelerated shall, in addition to any
                  and all installments of Basic Rent already due and payable and
                  in arrears, be deemed due and payable as if, by the terms and
                  provisions of this Lease, such accelerated Basic Rent were on
                  that date payable in advance. In the event of such
                  acceleration, Landlord shall use commercially reasonable
                  efforts to relet the Premises and shall credit Tenant, up to
                  the amount of accelerated Basic Rent and other charges
                  actually received by Landlord, for the amount of rent actually
                  received from such reletting.

                  27.2.3   Landlord may proceed with eviction proceedings as
                  allowed by applicable law. Upon recovering possession of the
                  Premises as a result of a default on the part of Tenant,
                  Landlord may, at Landlord's option, either terminate this
                  Lease or make such alterations and repairs as may be necessary
                  in order to relet the Premises and relet the Premises or any
                  part of parts thereof, either in Landlord's name or otherwise,
                  for a term or terms which may, at Landlord's option, be less
                  than or exceed the period which would otherwise have
                  constituted the balance of the Term and at such rent or rents
                  and upon such other terms and conditions as in Landlord's sole
                  discretion may seem advisable and to such person or persons as
                  may in Landlord's discretion seem best; upon each such
                  reletting all rents received by Landlord from such reletting
                  shall be applied: first, to the payment of reasonable costs
                  and expenses of such reletting, including brokerage fees and
                  attorney's fees and all costs of such alterations and repairs;
                  second, to the payment of any indebtedness other than Basic
                  Rent due hereunder from Tenant to Landlord; third, to the
                  payment of Basic Rent and Additional Monetary Obligations due
                  and unpaid hereunder; and the residue, if any, shall be held
                  by Landlord and applied in payment of future Basic Rent and
                  Additional Monetary Obligations as the same may become due and
                  payable hereunder. If such rentals received from such
                  reletting during any month shall be less than that to be paid
                  during that month by Tenant, Tenant shall pay any

                                       22

<PAGE>

                  such deficiency to Landlord. Such deficiency shall be
                  calculated and paid monthly. No such re-entry or taking
                  possession of the Premises or the making of alterations or
                  improvements thereto or the reletting thereof shall be
                  construed as an election on the part of Landlord to terminate
                  this Lease unless written notice of such intention be given to
                  Tenant. Landlord shall in no event be liable in any way
                  whatsoever for failure to relet the Premises or, in the event
                  that the Premises or any part or parts thereof are relet, for
                  failure to collect the rent under such reletting. Effective
                  upon an event of default, and giving effect to applicable
                  notice and cure periods, Tenant, for Tenant and Tenant's
                  successors and assigns, hereby irrevocably constitutes and
                  appoints Landlord Tenant's and their agent to collect the
                  rents due and to become due under all subleases of the
                  Premises or any parts thereof without in any way affecting
                  Tenant's obligation to pay any unpaid balance of Basic Rent
                  due or to become due hereunder. Notwithstanding any such
                  reletting without termination, Landlord may at any time
                  thereafter elect to terminate this Lease for such previous
                  breach.

                  27.2.4   To terminate this Lease and the Term hereby created
                  without any right on the part of Tenant to waive the
                  forfeiture by payment of any sum due or by other performance
                  of any condition, term or covenant broken. Whereupon Landlord
                  shall be entitled to recover, in addition to any and all sums
                  and damages for violation of Tenant's obligations hereunder in
                  existence at the time of such termination, damages for
                  Tenant's default in an amount equal to the amount of the Basic
                  Rent reserved for the balance of the Term, discounted at the
                  rate of eight and one half percent (8.5%) per annum to its
                  then present value, all of which amount shall be immediately
                  due and payable from Tenant to Landlord. In such event,
                  Landlord shall use commercially reasonable efforts to relet
                  the Premises and, if the Premises is relet, shall reimburse to
                  Tenant at the time of the receipt of payment, less reasonable
                  actual transaction costs incurred by Landlord in reletting the
                  Premises, a pro rata monthly amount, or lump sum amount,
                  which, if discounted at eight and one half (8.5%) per annum
                  and if presumed to be paid by the new tenant throughout the
                  then remaining Term, would equal the present value amount paid
                  by the Tenant to Landlord pursuant to the terms of this
                  Section 27.2.4. Landlord's reimbursement to Tenant of a lump
                  sum amount hereunder is dependent upon Landlord's ability to
                  refinance its interest in the Premises. Landlord shall use
                  commercially reasonable efforts to obtain such financing.

         27.3.    Default by Landlord. If Landlord defaults in the performance
         or observance of any provision of this Lease, Tenant shall give
         Landlord notice specifying in what manner Landlord has defaulted, and
         if such default shall not be cured by Landlord within the time period
         set forth in Section 27.5 below, Tenant may cure such default and
         invoice Landlord for the reasonable and necessary costs and expenses
         (including, without limitation, reasonable attorneys' fees and court
         costs) incurred by Tenant therefor, plus interest

                                       23

<PAGE>

         thereon. Notwithstanding the foregoing, if any default by Landlord in
         the performance of its obligations under this Lease shall result in an
         Emergency, and Landlord does not commence to cure the Emergency within
         48 hours, Tenant shall have the right, but not the obligation, to
         undertake such minimum remediative actions as are required to avoid or
         minimize such Emergency without waiting for the expiration of the
         notice and/or cure periods stated herein and Tenant shall invoice
         Landlord for the reasonable and necessary costs and expenses
         (including, without limitation, reasonable attorneys' fees and court
         costs) incurred by Tenant therefor, plus interest thereon.

         27.4.    Non-Waiver by Either Party. Failure by either party to
         complain of any action, non-action or default of the other party shall
         not constitute a waiver of any aggrieved party's rights hereunder.
         Waiver by either party of any right for any default of the other party
         shall not constitute a waiver of any right for either a subsequent
         default of the same obligation or for any other default, past, present
         or future.

         27.5.    Grace Period. Notwithstanding anything hereinabove stated,
         except in the case of an Emergency, and except in the event of a
         default by Tenant with respect to its obligations under Section 7,
         neither party hereto will exercise any right or remedy provided for in
         this Lease or allowed by law because of any default of the other,
         except those remedies on the part of Landlord contained in Section
         27.2.1, unless such party shall have first given ten (10) days written
         notice thereof to the defaulting party with respect to a monetary
         default and thirty (30) days written notice thereof with respect to a
         non-monetary default, and the defaulting party shall have failed to
         cure the default within such period; provided, however, that if the
         default consists of something other than the failure to pay money and
         cannot reasonably be cured within thirty (30) days, neither party
         hereto will exercise any such right or remedy if the defaulting party
         begins to cure the default within the thirty (30) days and continues
         actively and diligently in good faith to completely cure said default;
         and further provided that Landlord shall not be required to give such
         ten (10) days notice in the case of any payment default more than two
         (2) times during any twelve (12) month period.

         27.6.    Rights and Remedies Cumulative. No right or remedy herein
         conferred upon or reserved to Landlord or Tenant, as the case may be,
         is intended to be exclusive of any other right or remedy provided
         herein or by law, but each shall be cumulative and in addition to every
         other right or remedy given herein or now or hereafter existing at law
         or in equity or by statute.

28.      CONDITION OF TITLE AND OF PREMISES.

         28.1.    Landlord represents and warrants that it has good and
         marketable title to the Premises, subject only to such exceptions as
         are set forth on EXHIBIT K attached hereto (the "Permitted
         Encumbrances"). Tenant warrants that it has inspected the marketability
         of title and accepted the same. Landlord covenants and agrees that the
         Facility's HVAC systems and other Process Facility Systems (as defined
         in the Construction Addendum) shall be in good working order and in

                                       24

<PAGE>

         full compliance with Applicable Laws upon the delivery of the Premises
         to Tenant.

         28.2.    Notwithstanding the foregoing, Landlord agrees that, upon
         completion of the Facility, Landlord shall prepare and deliver to
         Tenant copies of all warranties and guaranties relating to the
         construction thereof and all systems, machinery and equipment
         (including the Equipment) contained therein. Landlord agrees to obtain
         the warranties and guaranties set forth on EXHIBIT L attached hereto.
         To the extent permitted by such warranties and guaranties, Landlord
         shall assign the same to Tenant. To the extent not so permitted,
         Landlord shall forward to Tenant the benefit of and right to enforce
         the same in Landlord's name. Notwithstanding any previous assignment to
         Tenant, Landlord shall have the right to enforce on its own behalf and
         with respect to its own obligations, any warranty or guaranty relating
         to the Facility and all systems, machinery, and equipment contained
         therein.

         28.3.    In the event that (i) there shall be any defect(s) in
         workmanship, materials, or design, with respect to any portion of the
         Work (as defined in the Construction Addendum), (ii) except in the case
         of an Emergency, Tenant shall have attempted in good faith, for a
         period of at least one (1) month, to enforce the above described
         warranties or guaranties that are applicable to the defect(s) in
         workmanship, materials, or design, and (iii) the party originally
         providing the warranty or guaranty shall refuse or fail to honor or
         perform the warranty or guaranty, then Landlord agrees that it shall,
         at its sole cost and expense and with all due diligence, repair,
         replace or correct, or cause to be repaired, replaced or corrected any
         defect(s) in workmanship, materials, or design, with respect to any
         portion of the Work, specified in a written notice or notices given by
         Tenant to Landlord within the applicable period of such original
         warranty or guaranty. Landlord shall have no obligation to Tenant under
         this Section 28.3 after the expiration of any such original warranty or
         guaranty.

         28.4.    Tenant shall not knowingly or negligently suffer or permit the
         Premises or any portion thereof to be used by the public without
         restriction or in such manner as might reasonably tend to impair
         Landlord's title to the Premises or in such manner as might reasonably
         make possible a claim or claims of adverse usage or adverse possession
         by the public, as such, or of implied dedication of the Premises or any
         portion thereof.

31.      ESCROW DEPOSIT. Tenant has previously deposited into escrow with HSBC

         Amount") to be utilized in accordance with the terms of that certain
         Escrow Agreement made as of April 5, 2001, among Landlord, Tenant and
         Escrow Agent (the "Escrow Agreement"). Landlord shall reimburse Tenant

         of tax exempt bonds on or before that date which is twelve (12) months
         from and after the date of Approval, Tenant shall have the right to (i)
         exercise its rights and remedies as mortgagee and holder of the
         security interest in the Premises and (ii) to apply such outstanding
         due amount (plus interest thereon) as an offset against the Basic Rent
         due under this Lease.

32.      ADDITIONAL CONTRIBUTION. Tenant has previously expended [$3,440,000] to
         pay for detailed engineering and shop drawings, which amount is
         separate from and in addition to the Escrow Amount deposited by Tenant
         in accordance with Section 31. Such amount will be refunded and paid to
         Tenant by Landlord as soon as possible, but in any event, no later than
         by consecutive monthly installation payments the amount of which will
         not be less than one-sixth (1/6th) of such amount, with the first such
         payment being due and owing, without invoice or notice by Tenant to
         Landlord on the day sixty (60) days after the date of execution of this
         Lease, and remaining payments to be due and owing on the same calendar
         day in each successive month until such amount is paid in full.

         Tenant has executed and delivered to [Tiger Trust] (the "Lender") that
         certain Warrant to Purchase Class A Common Stock of Biopure Corporation
         (the "Warrant"). The Warrant includes a Repurchase Option to Tenant,
         more particularly described therein, and provides that the funds used
         to repurchase any of the shares upon Tenant's exercise of the
         Repurchase Option will be deposited by Lender into an escrow account
         and applied either (i) to the final payments of Basic Rent owed under
         this Lease, or (ii) as a credit on the

         Purchase Price in the event Tenant exercises its Option to acquire the
         Premises under Section 2.2 of this Lease, as more particularly
         described in the Warrant.

Lease and for other good and valuable consideration, and intending to be legally
bound, each party hereto has caused this Lease to be duly executed under seal.

                   TERMS AND CONDITIONS OF OPTION TO PURCHASE

         As set forth in Section 2.2 of the Lease, Tenant (or "Buyer") shall
have the option to purchase the Premises from Landlord (or "Seller"), at any
time during the Term from and after the third anniversary of the Construction
Commencement Date, pursuant to and in accordance with the following terms and
conditions. Capitalized terms not specifically defined in this EXHIBIT B will
have the same meanings as ascribed thereto in the Lease.

1.       Purchase Price. The purchase price (the "Purchase Price") for the
Premises shall be the sum of the remaining payments of Basic Rent from the
Closing Date (as defined below) through the Expiration Date of the Lease,
reduced to present value utilizing a discount rate of eight and one-half percent
(8.5%) per annum.

2.       Survey and Title Insurance. Within thirty (30) days of receipt of
notice by Landlord pursuant to Section 2.2, Seller shall deliver to Buyer a
current ALTA/ACSM survey of the Premises and a title commitment from a title
insurance company acceptable to Buyer committing to insure the Deed (as defined
below), in the amount of the Purchase Price, subject only to exceptions
permitted in paragraph 3 below. Buyer shall have ten (10) days after its receipt
of the title commitment and the survey, whichever is received last, in which to
examine the same and determine any objections thereto. Provided, Buyer expressly
waives objection to all Permitted Encumbrances (as defined in the Lease). If
Buyer provides written objection to any matters in the title commitment or
survey, within such ten (10) day period, then Seller shall have sixty (60) days
thereafter to cure defects. If Seller cannot cure the defects, within such sixty
(60) day period, after making a good faith effort to do so, Buyer may decline to
close on the purchase of the Premises. Notwithstanding the foregoing, Seller
shall cure any title exceptions which may be cured by the payment of money
(i.e., liens, mortgages, taxes, etc. that Tenant is not obligated to satisfy
pursuant to the terms of the Lease) and such amounts may be deducted from the
Purchase Price at Closing. Seller shall cause the title insurance company to
issue its title insurance policy in favor of Buyer at the Closing, as provided
above.

3.       Conveyance and Permitted Exceptions. Upon payment of the Purchase
Price, Seller shall convey title and possession of the Premises to Buyer by
limited warranty deed (the "Deed") in form reasonably acceptable to Buyer and
proper for recordation in Sumter County, South Carolina subject to the following
permitted exceptions:

(a)      real property taxes for the year of Closing and thereafter;

(b)      zoning and land use ordinances and regulations adopted by a
         governmental authority;

(c)      matters created by Buyer; and

                                      B-1

<PAGE>

(d)      the Permitted Encumbrances (as defined in the Lease).

Seller shall convey title to the Equipment (as defined in the Construction
Addendum) to Buyer by a bill of sale in form and substance reasonably acceptable
to the parties and their respective counsel. Seller and Buyer shall execute and
deliver closing statements and such other documents as may be reasonably
required by the parties or the title insurance company or any mortgagee to
complete Closing and accomplish transfer of the Premises to Buyer hereunder.

4.       Closing Costs and Prorations. Seller shall pay all documentary deed
stamps/deed recording fees and deed transfer taxes, if any, costs of recording
any corrective instruments, one-half of the survey cost and Seller's attorney's
fees and costs. Buyer shall pay the nominal cost of recording the Deed, any
financing obtained, the title insurance premium, one-half of the survey cost and
Buyer's attorney's fees and costs.

5.       Time and Place of Closing. Closing shall occur not later than fifteen
(15) days following the notice period provided to Seller pursuant to paragraph 2
above (but in any event not later than fifteen (15) days following cure of all
of Buyer's objections) at the offices of Seller's counsel, commencing at 10:00
a.m. or at such other time and place as may be mutually agreed upon by the
parties. The actual date of Closing is referred to herein as the "Closing Date".

6.       Brokerage. Each party represents and warrants that no broker of any
kind has been consulted in connection with this transaction. Each party shall be
responsible for paying any broker with whom such party dealt.

7.       Seller's Affidavit. At the Closing, Seller shall execute and deliver to
Buyer and the title insurance company an affidavit to the effect that (a) no
labor, services or materials have been furnished to the Premises on behalf of
Seller for which any sums remain unpaid, there are no mechanic's liens against
the Premises resulting from any work performed by or on behalf of Seller, and
Seller has no knowledge of any person or entity entitled to file a mechanic's
lien against the Premises; (b) there are no persons or entities in possession of
the Premises other than the Buyer; (c) there are no encumbrances affecting the
Premises other than the Permitted Encumbrances; and (d) no action, suit or other
proceeding is pending or has been threatened that concerns or involves the
Premises or Seller's interest therein.

8.       Assignment. Buyer may assign this Option to any third party upon
written notice to Seller.

9.       Continuing Effect. This Option shall be deemed a continuing option to
acquire the Premises notwithstanding that Landlord subsequently may convey its
interests in the Premises to a third party, it being understood that the Option
will be binding upon Landlord's successors and assigns.

Construction Contractor to prepare (and, as appropriate, revise) site plans,
concept plans, foundation and construction documents and other plans, drawings,
specifications and construction and Process documents for the Facility as
specified and in accordance with the relevant time-frames set forth on the
Construction Schedule. All such plans, drawings, specifications, procedures and
other construction and Process documents will be consistent in all material
respects with the scope, design and general quality of the Facility as reflected
in the Review Plans and Specifications. All such plans, drawings,
specifications, procedures, construction and Process documents will be submitted
to Tenant and Tenant's Consultant (if any), not for Tenant's approval, but only
to allow Tenant to confirm that the same are consistent in all material respects
with the scope, design and general quality of the Facility as reflected in the
Review Plans and Specifications, and Tenant may, by appropriate marking, provide
specific indications of any non-compliance with the Review Plans and
Specifications or any requested revisions. Tenant will provide specific
indications of any non-compliance with the Review Plans and Specifications or
requested revisions to any items submitted (or resubmitted) pursuant to this
Section 2.1.1 no later than ten (10) Business Days after receipt by Tenant. The
failure of Tenant to notify Landlord of any non-compliance or requested
revisions within ten (10) Business Days after Tenant's receipt of such items
will be deemed to be a lack of objection thereof by Tenant.

                 2.1.2    Final Plans and Specifications. Upon final approval
by the required party or parties of each part of the plans, drawings,
specifications, procedures and construction and Process documents for the
Facility, whether actual or deemed as set forth in this Section 2.1, two (2)
sets thereof will be initialed by, and delivered to, Landlord and Tenant to
reflect their applicability to the Lease and same will become a part of the
Process Facility Plans.

                 2.1.3    Cooperation. Notwithstanding anything contained in
this Section 2.1 to the contrary, it is the intent of Landlord and Tenant to
proceed as quickly as reasonably possible to resolve any issues regarding the
consistency of the proposed Process Facility Plans with the Review Plans and
Specifications and finalize the Process Facility Plans, and Landlord and Tenant
agree to fully cooperate with each other in an effort to accelerate the
completion and finalization of the Process Facility Plans.

                                       8

<PAGE>

         2.2     Effect of Approval. To the extent that Tenant's approval or
consent is required or contemplated hereunder, approval by Tenant or Tenant's
Consultant will (a) not relieve Landlord of responsibility for proper and
adequate design, engineering, procurement, construction, installation,
interconnection, testing, performance of the Work and Installation Qualification
of the Facility, and (b) not be deemed approval by Tenant of any extension of
the period in which Landlord is to Substantially Complete the Facility, as
provided in this Addendum or the Lease. Landlord will ensure that the structure
and detail of the utilities, including the Utilities, and the mechanical,
electrical and other Process Facility Systems meet all applicable Legal
Requirements and the Process Facility Plans and that all of the Work satisfies
all Legal Requirements. Landlord will obtain from Construction Contractor, and
from any electrical, mechanical or structural engineer providing services for
the design or construction of the Facility (including the Engineer), and from
the original manufacturers of the Equipment, warranties and guarantees, in a
form acceptable to Landlord, in Landlord's reasonable discretion, as to the
sufficiency and adequacy of the construction and installation of the Facility
and the Process Facility Systems. Landlord will obtain from Construction
Contractor (or its designated design professional) a certificate, in a form
acceptable to Landlord, in Landlord's reasonable discretion, as to the
sufficiency and adequacy of the design of the Facility and the Process Facility
Systems.

         2.3     Construction Contract for Facility. Landlord may solicit bids
for or enter into on a negotiated basis Construction Contracts for the design,
engineering, and construction of the Facility (including, without limitation, a
Construction Contract based upon a fixed, lump sum price for the construction of
the Facility), as determined by Landlord; provided, however, that any
substitution or replacement of Construction Contractor must be approved in
writing by Tenant, which approval will not be unreasonably withheld or delayed.
Landlord will include a provision in any Construction Contract naming Tenant as
an express third party beneficiary, such that Tenant may, at its election,
assert a direct right of interest thereunder; provided, however, that in no
event will there exist or be deemed to exist a contractual relationship between
Tenant and Construction Contractor or any other contractor. To the extent
practicable, Landlord will give Tenant and Tenant's Consultant (if any) two (2)
Business Days' prior notice of any pre-bid or pre-negotiation conferences with
Construction Contractor and major subcontractors who will perform the Work and
any replacement or substitute therefor, and will permit Tenant and Tenant's
Consultant (if any) to attend such meetings.

         2.4     Payment and Performance Bonds. Prior to commencing the Work,
Landlord will cause Construction Contractor to obtain payment and performance
bonds, or other security acceptable to Tenant in its sole discretion, covering
the faithful performance of the Construction Contract for the completion of the
Work. Such bonds shall be substantially in the form AIA Form A312, 1984 Edition,
with modifications to provide for coverage of costs of corrective work, shall be
in an amount equal to 100% of the contract price under the Construction
Contract, and conditioned on Construction Contractor's faithful performance of

3.       CHANGES IN PROCESS FACILITY PLANS AND COST OF CHANGES.

         3.1     Changes to the Process Facility Plans by Landlord. Landlord
will not, without the prior written consent of Tenant, make, or permit to be
made, any material changes or any other changes in the Process Facility Plans
which would materially and adversely affect Tenant's safe, reliable and
efficient use, enjoyment, operation, or maintenance (to the extent that Tenant
is required to maintain pursuant to the terms of the Lease) of the Property or
approve or acquiesce in any material deviations from the Process Facility Plans.
Notwithstanding the foregoing, Landlord may, without the prior written consent
of Tenant, make, or permit to be made, material changes or any other changes in
the Process Facility Plans or approve or acquiesce in any material deviations
from the Process Facility Plans to the extent such changes or deviations are
required to comply with Legal Requirements or to correct construction defects or
hazardous conditions and Landlord will be solely liable and obligated to pay all
costs, expenses and changes relating to or resulting from such changes. From
time to time, Landlord may request, by submitting an analysis of the additional
cost or savings and change, if any, in the Substantial Completion date, that
Tenant approve any changes in the Process Facility Plans, or to the Work already
installed prior to Substantial Completion. If Tenant should fail to disapprove
in writing such change requested by Landlord within ten (10) days following
receipt thereof, the same will be approved in all respects by Tenant, and
Landlord will be authorized to make such requested change. Unless otherwise
approved in writing by Tenant, Landlord will be solely liable and obligated to
pay all costs, expenses and changes relating to or resulting from any changes to
the Process Facility Plans requested by Landlord. No change in the Process
Facility Plans requested by Landlord, unless otherwise approved in writing by
Tenant, will be the basis of any Tenant Delay.

         3.2     Changes to the Process Facility Plans by Tenant. From time to
time after Tenant has reviewed the Process Facility Plans, Tenant may request
Landlord to make changes in the Process Facility Plans or to the Work already
installed prior to Substantial Completion. Any changes to the Process Facility
Plans so requested by Tenant (herein referred to as "Tenant's Changes") will be
subject to Landlord's prior written approval, which will not be unreasonably
withheld. Landlord will, within ten (10) days following receipt of Tenant's
proposed changes, deliver to Tenant (a) a statement of the estimated change, if
any, in the cost of design, engineering or construction of the Facility (the
"Facility Cost") in connection with such Tenant's Changes as above provided, and
(b) an estimate of the period of time, if any, that such Tenant's Changes will
delay the Substantial Completion of the Facility. In the case of Tenant's
Changes requested prior to the awarding of a Construction Contract for the
subject work, Landlord's statement of estimated change in the Facility Cost will
be based on a good faith estimate of such costs by Landlord and, in the case of
Tenant's Changes requested after the awarding of a Construction Contract for the
subject work, the statement of estimated change in Facility Cost will be based
on the proposed change order to the Construction Contract to be issued and
approved by Landlord for such Tenant's Changes. If Tenant shall fail to approve
in writing Landlord's submission within ten (10) days following receipt thereof,
the same will be deemed disapproved in all respects by Tenant, and Landlord will
not be authorized to make the change. If Tenant

                                       10

<PAGE>

approves in writing the statement of cost and the delay in Substantial
Completion as submitted by Landlord, [Tenant shall place funds in the amount of
the approved costs in a construction escrow account (the "Construction Escrow")
with a national banking institution and subject to terms and conditions which
are mutually acceptable to Landlord and Tenant and] Landlord will promptly cause
the Process Facility Plans to be modified to provide for such change and will
submit such modified Process Facility Plans to Tenant. Landlord shall submit to
Tenant and Tenant's Consultant with the monthly progress report provided in
accordance with Section 4.3 an invoice and accounts, records, invoices, and
evidences of payment as Tenant may reasonably request to evidence the costs for
the portion of the increase in Facility Cost arising from the approved change
for Work performed in the prior month. Tenant shall within thirty (30) days of
the delivery of such invoice pay the undisputed portion thereof and provide to
Landlord and the Construction Escrow agent a detailed statement of the basis for
its non-payment or non-acceptance of any amount in dispute. All interest which
accrues on funds in the Construction Escrow will be to the benefit of Tenant,
unless Landlord is determined to have been entitled to payment of money disputed
by Tenant, in which case the interest accrued on such withheld amount in the
Construction Escrow shall be paid to Landlord.

         3.3     Accounting for Changes. During the performance of the Work,
Landlord will cause to be submitted to Tenant and Tenant's Consultant monthly
progress reports prepared by Construction Contractor as to the Work, specifying
any change in the estimated date of Substantial Completion, and showing the
progress of the Work, and, as to those items for which the cost is the
responsibility of Tenant, the amount of estimated costs and/or savings
attributable to any approved changes under Section 3.1 and Section 3.2 or delay
of any kind including Tenant Delay. Landlord will submit to Tenant such
accounts, records, invoices, and evidences of payment as Tenant may reasonably
request to evidence the costs or savings as to those items for which the cost is
the responsibility of Tenant or for which the savings will benefit Tenant. All
changes will be submitted on a lump sum basis. Approval of proposed changes
shall be in accordance with Sections 3.1 and 3.2. Landlord will cause Contractor
to track all changes weekly and summarize changes in a monthly report, which
shall be delivered to Tenant upon receipt by Landlord. Tenant will be obligated
to pay the fees (including, but not limited to, the fees of any professionals
engaged and utilized by Landlord), expenses, and charges of Landlord and all
contractors, subcontractors, suppliers, materialmen, and laborers to the extent,
but only to the extent, that such fees, expenses, and charges are directly
incurred as a result of Tenant's Changes or Tenant Delay.

4.       CONSTRUCTION OF THE FACILITY

         4.1     Performance. Landlord will cause to be furnished, installed,
and performed completely all of the Work as shown on and in strict accordance
with the Process Facility Plans, as modified by approved changes as provided in
Article 3. Landlord will be fully responsible for all matters that must be
accomplished to complete the Work in accordance with the provisions of this
Addendum including, without limitation, filing plans and other required
documentation with the proper Governmental

                                       11

<PAGE>

Authority, securing all necessary permits, supervising all details of the Work,
and promptly removing or otherwise handling to Tenant's reasonable satisfaction
all mechanics', materialmen's and like liens from the public record by payment
or surety bond. Landlord will cause all construction on or in the Facility to be
performed in strict accordance with all applicable Legal Requirements in a good
and workmanlike manner and in strict accordance with good construction and
engineering practices accepted in the pharmaceutical industry, free from
material defects (structural, mechanical, or otherwise) in design, workmanship,
and materials, and with new materials (unless otherwise specified in the Process
Facility Plans), all as more specifically set forth in the Process Facility
Plans.

         4.2     Non-Liability of Tenant. Subject to the terms and conditions
of Sections 4.4 and 4.5, Tenant will not be liable for any injury, loss, or
damage to any person (including, but not limited to, death) or property on or
about the Property during construction until the time of Substantial Completion,
unless directly caused by Tenant, its employees, agents, or invitees, and
Landlord will indemnify and save Tenant harmless against and from any such
liability, and any costs or charges (including, without limitation, reasonable
attorneys' fees and court costs) which Tenant may incur on account of such
injury, loss, or damage.

         4.3     Information; Monthly Report. During the period prior to
achievement of Installation Qualification, Landlord will provide all reasonable
cooperation to keep Tenant informed as to material aspects pertaining to the
design, engineering, procurement, construction, installation, interconnection,
testing, and Installation Qualification of the Facility. Accordingly, upon
written request, Landlord will furnish Tenant's Designated Representative (as
defined below) with copies of all progress reports, correspondence, or other
information as may be material and pertinent to the Property, other than
internal communications or confidential matters between Landlord and its
attorneys or accountants. Tenant's Designated Representative and Tenant's
Consultant (if any) will have the right to attend scheduled meetings material to
the interest of Tenant as may be held with respect to the Property between
Landlord, Construction Contractor and any other outside person or firm (other
than Landlord's attorneys or accountants) furnishing materials, services, or
labor to or with respect to the Property. Landlord agrees to provide Tenant with
reasonable prior notice of any scheduled meetings material to the interest of
Tenant, but will not be obligated to attempt to schedule any such meetings to
accommodate Tenant's availability or convenience. Furthermore, Tenant's failure
to timely attend any such scheduled meetings will not constitute a basis for any
claim by Tenant that Landlord has violated the foregoing provisions. Prior to
the Term Commencement Date, Landlord and its construction team will meet no less
frequently than once each month to discuss and analyze the progress of
construction and Landlord will prepare and deliver to Tenant a written report
(which may be in the form of the minutes of the meeting) (the "Construction
Meeting Report") summarizing the material items discussed at such meeting and
the effect of such items, if any, on the Construction Schedule. Each
Construction Meeting Report will specifically identify any event or condition
which would constitute an Excusable Delay or a Tenant Delay (and any incurred
cost directly or

                                       12

<PAGE>

indirectly resulting from a Tenant Delay) which has occurred since issuance of
the immediately prior Construction Meeting Report.

         4.4     General Access. Landlord will afford or will obtain for
Tenant, its employees, and its representatives regular access during normal
business hours to the (i) Land and the Facility, all materials thereon and
therein, and all Work being performed thereon and therein, and (ii) the premises
and facilities of any subcontractors or vendors, and the materials therein
relating to the Work; provided, however, that in exercising such right of
access, Tenant and its employees and representatives will comply with all
applicable laws and regulations (including, but not limited to, all construction
site rules and safety regulations and to all OSHA safety regulations and
standards) and will coordinate such access with Construction Contractor. Tenant
will be required to provide at least twenty-four (24) hours prior notice to
Construction Contractor for the purpose of coordinating Tenant's entry onto the
Property with Work then in progress. Tenant acknowledges that its ability to
gain entry to the Property occasionally may be limited or restricted due to the
particular stage of Work then in progress. Tenant will be accompanied by a
representative of Landlord or Construction Contractor except during periods in
which Tenant, its employees and representatives will be engaged in the
installation of Tenant's FF&E as provided in Section 4.5. Tenant or its agents
will be required to attend and complete the required training by Construction
Contractor prior to being granted unescorted access to the Land and the
Facility.

         4.5     Installation of Tenant's FF&E and Qualification Activities;
Early Occupancy.

                 4.5.1    At such time as the Facility will be in a state
suitable for the commencement of (i) the installation of Tenant's personal
property (as reasonably determined by Landlord in good faith), which in any
event will be no later than the Early Occupancy Date, (ii) activities by Tenant
and its contractors and consultants to achieve Operation Qualification,
Performance Qualification and Process Validation, Tenant and its employees,
agents, contractors, and subcontractors may enter upon the Property for the
purpose of (x) installing and arranging Tenant's furniture, furnishings, office
equipment, artwork, trade fixtures and other property (the "FF&E") (y)
performing activities necessary or incidental to the achievement of Operation
Qualification, Performance Qualification and Process Validation and (z)
otherwise making the Property ready for Tenant's use and occupancy. In
exercising such right of access, Tenant and its employees and agents will comply
with all reasonable standards and regulations established by Landlord and will
coordinate their efforts with Construction Contractor to facilitate timely
completion of all Work, and maintenance of the Property in a safe condition.
During performance of any such work, Tenant's employees and agents will also
coordinate with Landlord the delivery, storage, movement and installation of
FF&E. Any work performed by Tenant's employees and agents will be conducted in
such manner so as to maintain harmonious labor relations and not to interfere
with or delay Construction Contractor or Landlord's Work. Landlord will provide
Tenant's employees and agents with reasonable access to the Property for the
purpose of making inspections and taking measurements in advance of the period
for the

                                       13

<PAGE>

installation of Tenant's FF&E and commencement of activities for achievement of
Operation Qualification, Performance Qualification and Process Validation;
provided that the construction of the Facility will have reached a point in
Landlord's reasonable judgment such that Landlord will not be unreasonably
delayed or hampered in the completion thereof by permitting such access. In
connection with the access permitted under this Section 4.5, Tenant covenants
(xx) to cease immediately upon request by Landlord any activity or work during
any period which, in Landlord's reasonable judgment, will unreasonably interfere
with or delay Landlord's prosecution or completion of the Work, or in Landlord's
or Construction Contractor's reasonable judgement will create any unsafe
condition at the Property, (yy) that such access will be at the sole risk of
Tenant and will be deemed to be a license, and (zz) that prior to exercising
such right, Tenant will deliver to Landlord such certificates of insurance
evidencing such insurance as may be required by Landlord, in Landlord's
reasonable discretion, including public liability, property damage and worker's
compensation to protect Landlord, Construction Contractor and Tenant during the
period of Tenant's access. Tenant will not permit any mechanic's or
materialman's lien to be placed upon the Property caused by or resulting from
any work performed, materials furnished or obligation incurred in connection
with the installation of Tenant's FF&E or activities necessary for or incidental
to achievement of Operation Qualification, Performance Qualification and Process
Validation and, in the case of the filing of any such lien Tenant will promptly
pay same or bond around such claims to the satisfaction of Landlord, in
Landlord's reasonable discretion. Landlord will furnish at no additional cost to
Tenant and Tenant's employees and agents water, electricity, adequate elevator
service (freight and passenger) to move personnel and FF&E within the capacity
and purpose for which they are designed, and HVAC to the Facility, if available,
during the installation and the aforementioned activities by Tenant, if any,
during the normal working hours of the construction of the Facility.

                 4.5.2    Elevators and equipment will be suitable to lift
Tenant's materials and personnel within the capacity limitations shown on the
Review Plans and Specifications. Subject to priority of use given to Landlord's
contractors and subcontractors, Landlord will furnish at no additional cost to
Tenant equipment and hoists to elevate and lift Tenant's FF&E and personnel,
equipment and materials necessary for or incidental to achievement of Operation
Qualification, Performance Qualification and Process Validation, but only to the
extent that such equipment and hoists are still being used by Landlord and are
physically situated on the Land. Landlord will have the right to remove the
equipment and hoists at any time the same are no longer needed by Landlord for
the construction of the Facility, provided that Landlord shall provide Tenant
ten (10) days advance notice of such intent. Landlord will designate the method
established for scheduling equipment, elevator and hoist use.

                 4.5.3    From and after the Early Occupancy Date, Tenant will
have the right to use, occupy and operate the Facility for the purposes
permitted under the Lease, provided that Tenant does not interfere with or delay
Construction Contractor or Landlord's Work. Any such use, occupancy and
operation by Tenant will be subject to the same terms and conditions of the
Lease, provided however, that no Annual Rent will

                                       14

<PAGE>

accrue and be due and payable during the period from the Early Occupancy Date
to the Rent Commencement Date (as defined in Section 5.1 of the Lease).

         4.6     No Assumption of Responsibility. Except as otherwise expressly
provided herein, neither the exercise nor the failure to exercise by Tenant or
its representatives of any right afforded Tenant under this Addendum (including
specifically, but without limitation, the exercise or the failure to exercise of
a right to review, comment upon, approve, or disapprove documents, plans,
specifications, drawings, or other matters, or the performance by Landlord) or
the failure by Tenant to insist upon the performance by Landlord of any
obligation imposed upon Landlord under this Addendum, will (a) impose upon
Tenant, or be deemed to be an assumption by Tenant, of any obligation or
liability with respect to the design, engineering, procurement, construction,
installation, interconnection, testing or Installation Qualification of the
Facility, or (b) constitute or be deemed to constitute acquiescence by Tenant to
any act or failure to act on the part of Landlord which is in conflict with any
provision of this Addendum. The parties acknowledge that Tenant has provided
design criteria in the form of process and instrumentation diagrams from an
existing facility and other guidance which is documented in "Notes of Meetings"
issued by the Engineer and comments provided in writing on documents submitted
by the Engineer for Tenant review that have been used by Landlord to develop the
Process Facility Plans.

         4.7     Designated Representatives. Landlord and Tenant each hereby
appoint a representative (each a "Designated Representative"), and in the event
that a Designated Representative is unavailable for any reason whatsoever, an
alternative representative (each an "Alternative Representative"), to make
timely binding decisions on design, development and construction matters (but
not other matters) relating to the Facility. The Designated Representatives are:

         Landlord                 Ray E. Gentry

         Tenant                   Geoffrey J. Filbey

The Alternative Representatives are:

         Landlord                 James Wilson

         Tenant                   Donald Clarkson

At any time and from time to time hereafter, Landlord and Tenant will each have
the right to appoint a successor or substitute Designated Representative and/or
Alternative Representative to act on behalf of such party, each such appointment
to be effected by delivering ten (10) days' prior written notice to the other
party hereto in accordance with the terms and provisions of Section 29 of the
Lease. Any action which may be taken by a Designated Representative may also be
taken by an Alternative Representative and any party may rely thereon as if such
action had been taken by the Designated

                                       15

<PAGE>

Representative and such party will have no duty to inquire why the Designated
Representative was unavailable to act.

5.       COST OBLIGATIONS

         5.1     Landlord's Cost. Except as otherwise specifically provided in
Article 3, Landlord will be liable and obligated to pay for all costs of
preparation of the Process Facility Plans and all costs related to the design,
engineering, procurement, installation, construction, interconnection, testing
and Installation Qualification of the Facility, including, but not limited to,
all labor and materials. All such costs will be included in the Project Cost as
defined in Section 5 of the Lease; provided, however, that certain Qualified
Expenses (as defined in the Escrow Agreement) relating to the acquisition of the
Land, and the design, engineering and construction of the Facility, will be paid
out of the Escrow Funds (as defined in the Escrow Agreement). Landlord will,
from and after the full execution of this Lease and until the delivery of
landlord's final written certification pursuant to Section 3.3 of the Lease,
deliver to Tenant on a monthly basis a written certification of the Project Cost
to date, specified by line item, consistent with the terms and requirements of
the Lease and this Addendum. Additionally, from and after the full execution of
the Lease, Landlord will provide to Tenant and Tenant's Consultant, during
normal business hours, full and complete access to all books, records and
accounts of Landlord to verify the amount of the Project Cost.

6.       SCHEDULE FOR CONSTRUCTION

         6.1     Time to Completion. Time is of the essence to this Addendum.
Landlord will cause the completion of the Facility in strict accordance with the
Process Facility Plans, all applicable Legal Requirements, and the provisions of
this Addendum with due diligence, which requires Landlord to (a) Substantially
Complete the Facility on or before the Projected Completion Date, and (b) to
provide and perform Work to support and assist Tenant, as it pertains to Work
performed up through Installation Qualification, to achieve
Operation/Performance Completion as it pertains to Work performed up through
Installation Qualification, as extended by Excusable Delays and/or Tenant
Delays, in which case the Projected Completion Date may be, if adversely
affected by Excusable Delay and/or Tenant Delay, will be extended by one day for
each day of such Excusable Delay and/or Tenant Delay.

         6.2     Installation Acceptance Certificate. Landlord guarantees that
best efforts will be made so that Installation Qualification will be achieved on
or before the Projected Completion Date. Tenant agrees to accept the
Installation Acceptance Certificate within twenty (20) days from and after
achievement of Installation Qualification; provided, however, that such period
will be extended, if necessary, so that Tenant shall not be obligated to accept
the Installation Acceptance Certificate until ten (10) days after the date that
Tenant receives a copy of the as-built plans and specifications for the
Property, the reports and results of all trials, tests, and analyses necessary
and incidental to document achievement of Installation Qualification, together
with copies of the certificate of occupancy for the Facility, and all permits
related to the Property. Tenant's acceptance of the Installation Acceptance
Certificate shall not constitute a

                                       16

<PAGE>

waiver of any claims that Tenant may have pertaining to any matter that would
not have come to Tenant's attention in connection with a commercially reasonable
diligent investigation of the Property at the time of Tenant's acceptance of the
Installation Acceptance Certificate. If Tenant cannot accept the Installation
Acceptance Certificate because Tenant does not believe the certification
required therein to be true with respect to any significant matter, Tenant shall
accept the Installation Acceptance Certificate with such significant exceptions
and significant qualifications as it deems appropriate based on a certification
from Tenant's Consultant. If Landlord's disagrees with such exceptions and
qualifications and the parties are unable to resolve such disagreement for a
period of fifteen (15) days, then Landlord's Consultant and Tenant's Consultant
shall select a third person who is an independent design professional (the
"Independent Consultant"). The Independent Consultant shall resolve the dispute
in its sole and absolute discretion. If Landlord's Consultant and Tenant's
Consultant shall be unable to agree upon the appointment of the Independent
Consultant within ten (10) days after the end of such fifteen (15) day period,
they shall give written notice of such failure to each of Landlord and Tenant
and if Landlord and Tenant shall fail to agree upon the appointment of such
Independent Consultant within ten (10) days after the Tenant's Consultant and
Landlord's Consultant give such notice, then, within ten (10) days thereafter,
either of the parties upon notice to the other party may apply for such
appointment to the American Arbitration Association in Charlotte, North
Carolina. Landlord and Tenant shall each bear all the respective costs and
expenses of the consultants they respectively choose and shall share equally the
costs and expenses of selecting and authorizing any Independent Consultant. Upon
resolution of any such dispute, Tenant shall accept the Installation Acceptance
Certificate consistent with the Independent Consultant's determination. During
any dispute between Landlord and Tenant as to whether Installation Qualification
has been achieved by Landlord, Tenant shall occupy the Property and commence
paying Basic Rent (to the extent otherwise required under the Lease) as if the
date of Installation Qualification is the date originally designated by
Landlord; provided, however, that Tenant may state that such Basic Rent (or a
portion thereof) is being paid under protest. If the Independent Consultant
determines that the Facility had not achieved Installation Qualification on the
date initially designated by Landlord, (A) the Independent Consultant shall
include in its determination (i) a statement of the percentage of the Property
that was not available to Tenant and its consultants and contractors for the
achievement of Operation Qualification, Performance Qualification and/or Process
Validation for the period in which Tenant occupied the Property prior to
achievement of Installation Qualification by Landlord and (ii) the additional
costs and expense incurred by Tenant to achieve or cause the achievement of
Operation Qualification, Performance Qualification and Process Validation as a
result thereof and (B) Tenant shall be entitled to an abatement of Basic Rent
(i) in proportion to such percentage and (ii) the amount of such additional
costs and expense as determined by the Independent Consultant.

         6.3     Substantial Completion Acceptance Certificate. Landlord
guarantees that best efforts will be made so that Substantial Completion will be
achieved on or before the Projected Completion Date. Tenant agrees to accept the
Substantial Completion Acceptance Certificate within twenty (20) days from and
after the date of delivery by the Engineer. Tenant's acceptance of the
Substantial Completion Acceptance Certificate

                                       17

<PAGE>

shall not constitute a waiver of any claims that Tenant may have pertaining to
any matter that would not have come to Tenant's attention in connection with a
commercially reasonable diligent investigation of the Property at the time of
Tenant's acceptance of the Substantial Completion Acceptance Certificate. If
Tenant cannot accept the Substantial Completion Acceptance Certificate because
Tenant does not believe the certification required therein to be true with
respect to any significant matter, Tenant shall provide notice to Engineer and
Landlord of the exceptions and qualifications thereto as it deems appropriate
based on a certification from Tenant's Consultant. If Engineer or Landlord's
Consultant disagrees with the exceptions and qualifications taken by Tenant's
Consultant after trying to resolve a disagreement for a period of fifteen (15)
days, then any dispute regarding achievement and/or date of Substantial
Completion may be referred to arbitration by either party in accordance with the
Lease. During the pendency of any such dispute, Tenant may use, occupy and
operate the Property.

         6.4     Failure to Timely Proceed with Work. In the event Construction
Contractor is not progressing with its Work in accordance with the Construction
Schedule, and, as a result, the progression of the Work is at a stage that is
more than thirty (30) days behind schedule as provided in the Construction
Schedule, then Landlord shall cause Construction Contractor to take such
measures as are reasonably necessary to accelerate the progression of its Work
to bring the progression of the Work into compliance with the Construction
Schedule. In the event Construction Contractor is not progressing with its Work
in accordance with the Construction Schedule, and, as a result, the progression
of the Work is at a stage that is more than ninety (90) days behind schedule as
provided in the Construction Schedule, then, immediately upon Tenant's notice
and demand, Landlord shall cause such Construction Contractor to be removed and
shall replace such Construction Contractor with a new Construction Contractor
approved in writing by Tenant, in Tenant's reasonable discretion. In the event
Engineer is not progressing with its Work in accordance with the Construction
Schedule, and, as a result, the progression of the Work is at a stage that is
more than thirty (30) days behind schedule as provided in the Construction
Schedule, then Landlord shall cause Engineer to take such measures as are
reasonably necessary to accelerate the progression of its Work to bring the
progression of the Work into compliance with the Construction Schedule. In the
event Engineer is not progressing with its Work in accordance with the
Construction Schedule, and, as a result, the progression of the Work is at a
stage that is more than ninety (90) days behind schedule as provided in the
Construction Schedule, then, immediately upon Tenant's notice and demand,
Landlord shall cause such Engineer to be removed and shall replace such Engineer
with a new Engineer approved in writing by Tenant, in Tenant's reasonable
discretion.

         6.5     Failure of Substantial Completion. Notwithstanding anything to
the contrary herein contained, if (i) Substantial Completion of the entire
Facility has not occurred, (ii) one hundred eighty (180) days after the
Projected Completion Date have passed, as extended by Tenant Delay and/or
Excusable Delay, (iii) Construction Contractor is not progressing in its
performance of the Work, and (iv) Landlord's lender is not funding the
performance of the Work, then Tenant may terminate the Lease by

                                       18

<PAGE>

giving written notice of such election to Landlord in which event the parties
will have no further obligations and liabilities under this Lease except for
such obligations and liabilities which specifically survive the termination of
the Lease.

         6.6     Management Meetings. Landlord and Tenant will attempt to
resolve any disputes, disagreements or claims arising with respect to the
performance of obligations and duties under this Addendum by holding a meeting
of management or executive level representatives within fifteen (15) days of
written notice by a party of the existence of a dispute, disagreement or claim.
Such meetings will not relieve the parties from the performance of their
respective obligations under the Lease or this Addendum. Such meeting shall be
held at the offices of Tenant unless the parties agree otherwise. If as a result
of such meeting Landlord and Tenant are unable to resolve any such dispute,
disagreement or claim, the dispute shall be referred to arbitration in
accordance with the Lease. Landlord and Tenant agree that the arbitration of any
dispute, disagreement or claim arising under this Addendum will not be
consolidated or joined with any other action, arbitration or proceeding and
Landlord and Tenant hereby expressly waive and disclaim any right to request any
such consolidation or joinder.

7.       LEASE

         7.1     Term Commencement Date. The Term of the Lease will commence
upon the Term Commencement Date. On the Term Commencement Date, Landlord agrees,
that: (a) Landlord will deliver possession of the Facility, free of all leases
and tenancies (except the Lease), occupants, construction lien claims not
discharged or transferred to security within thirty (30) days of the filing
thereof, and material defects in material and workmanship; (b) the Facility will
be in strict compliance with all Legal Requirements; (c) the Property will not
be subject to any Title Exceptions except Permitted Exceptions; and (d) Landlord
will satisfy all those obligations imposed upon Landlord by the provisions of
the Lease and this Addendum which are required to be complied with prior to the
commencement of the Term of the Lease and this Addendum.

8.       GENERAL COVENANTS OF LANDLORD

         8.1     Compliance with Legal Requirements. From the date hereof until
the Term Commencement Date, Landlord shall, taking into account the then state
of construction, design, construct, own, occupy, lease, manage, maintain,
operate, and insure the Property, or cause the Property to be designed,
constructed, owned, managed, maintained, operated, and insured, in accordance
with all Legal Requirements other than as maybe applicable due solely to a
special use by Tenant and good industry practices.

Construction Contractor to obtain and maintain, from the date hereof until the
Term Commencement Date, at no cost to Tenant, builder's risk insurance,

statutory benefits covering employees of Construction Contractor and with such
endorsements as may be reasonably requested by Tenant. Landlord will deliver to
Tenant, promptly as same are issued, true and complete copies or certificates of
all policies of insurance, together with all subsequent endorsements thereto, as
are required to be obtained and maintained by Landlord pursuant to the terms
hereof. Any insurance required by the terms of this Section 8.2 to be carried by
Landlord may be under a blanket policy (or policies) covering other properties
of Landlord and/or its affiliates; provided, however that Landlord will procure
and deliver to Tenant a statement from the insurer or general agent of the
insurer setting forth the coverage maintained and the amounts thereof allocated
to the risks intended to be insured hereunder.
