3.1                               Term. The Commencement Date, Expiration Date and Term of this Lease are as specified in Paragraph 1.3.

3.2                               Delay in Possession. If for any reason Landlord cannot deliver possession of the Premises to Tenant by the Commencement Date, Landlord shall not be subject to any liability therefor, nor shall such failure affect the validity of this Lease or the obligations of Tenant hereunder. In such case, Tenant shall not, except as otherwise provided herein, be obligated to pay Rent or perform any other obligation of Tenant under the terms of this Lease until Landlord delivers possession of the Premises to Tenant. The term of the Lease shall commence on the earlier of (a) the date upon which Tenant takes possession of the Premises, or (b) ten (10) days following notice to Tenant that the Leasehold Improvements (as defined in the Tenant Improvements Addendum) are substantially complete (as such term is defined in the Tenant Improvements Addendum) and Landlord is prepared to tender possession of the Premises to Tenant. If possession of the Premises is not delivered to Tenant within sixty (60) days after the receipt of a building permit in respect of the Premises from the City of Grand Prairie and such delay is not due to Tenant’s acts, failure to act or omissions, then Tenant shall be entitled, as its sole remedy, to receive one (1) day’s rental abatement (effective as of the Commencement Date) for each day of delay beyond such sixty (60) day period. If possession of the Premises is not delivered to Tenant within ninety (90) days after the receipt of a building permit in respect of the Premises from the City of Grand Prairie and such delay is not due to Tenant’s acts, failure to act or omissions, then Tenant shall be entitled, as its sole remedy, to receive two (2) days’ rental abatement (effective as of the Commencement Date) for each day of delay beyond such ninety (90) day period. If possession of the Premises is not delivered to Tenant within one hundred twenty (120) days after the receipt of a building permit in respect of the Premises from the City of Grand Prairie and such delay is not due to Tenant’s acts, failure to act or omissions, then Tenant may, as its sole remedy, cancel this Lease by notice in writing to Landlord within ten (10) days after the end of said one hundred twenty (120)

3

day period, and in such event the parties shall be discharged from all obligations hereunder. If such written notice from Tenant is not received by Landlord within said ten (10) day period, Tenant’s right to cancel this Lease shall terminate. If the Commencement Date is after August 1, 1999, and is not the first day in a calendar month, then the Term shall end, and the Expiration Date shall be, the last day of the eighty-four (84) month period that begins on the first day of the first full calendar month of the Term.

3.3                               Commencement Date Certificate. At the request of Landlord, Tenant shall execute and deliver to Landlord a completed certificate (“Commencement Date Certificate”) in the form attached hereto as Exhibit B.

4.                                      Rent.

4.1                               Base Rent. Tenant shall pay to Landlord Base Rent and other monetary obligations of Tenant to Landlord under the terms of this Lease (such other monetary obligations are herein referred to as “Additional Rent”) in lawful money of the United States, without offset or deduction, in advance on or before the first day of each month. Base Rent and Additional Rent for any period during the term hereof which is for less than one full month shall be prorated based upon the actual number of days of the month involved. Payment of Base Rent and Additional Rent shall be made to Landlord at its address stated herein or to such other persons or at such other addresses as Landlord may from time to time designate in writing to Tenant. Base Rent and Additional Rent are collectively referred to as “Rent”. All monetary obligations of Tenant to Landlord under the terms of this Lease are deemed to be rent.

4.2                               Operating Expenses. Tenant shall pay to Landlord on the first day of each month during the term hereof, in addition to the Base Rent, Tenant’s Share of all Operating Expenses in accordance with the following provisions:

(a).                              “Operating Expenses” are all costs incurred by Landlord relating to the ownership and operation of the Industrial Center, Building and Premises including, but not limited to, the following:

(i)                                     The operation, repair, maintenance and replacement in neat, clean, good order and condition of the Common Areas, including parking areas, loading and unloading areas, trash areas, roadways, sidewalks, walkways, parkways, driveways, landscaped areas, striping, bumpers, irrigation systems, drainage systems, lighting facilities, fences and gates, exterior signs and tenant directories.

(ii)                                  Water, gas, electricity, telephone and other utilities servicing the Common Areas.

(iii)                               Trash disposal, janitorial services, snow removal, property management and security services.

(vii)                           Environmental monitoring and insurance programs.

(viii)                        Monthly amortization of capital improvements to the Common Areas and the Building, it being agreed that the monthly amortization of any given capital improvement shall be equal to the quotient obtained by dividing the cost of the capital improvement by Landlord’s estimate of the number of months of useful life of such

4

improvement.

(ix)                              Maintenance of the Building including, but not limited to, painting, caulking and repair and replacement of Building components, including, but not limited to, roof, elevators, mechanical, systems, and fire detection and sprinkler systems.

(xi)                              If Tenant fails to maintain the Premises, any expense incurred by Landlord for such maintenance.

(b)                                 Tenant’s Share of Operating Expenses that are not specifically attributed to the Premises or Building (“Common Area Operating Expenses”) shall be that percentage shown in Paragraph 1.5(a). Tenant’s Share of Operating Expenses that are attributable to the Building (“Building Operating Expenses”) shall be that percentage shown in Paragraph 1.5(b). Landlord in its reasonable discretion shall determine which Operating Expenses are Common Area Operating Expenses, Building Operating Expenses or expenses to be entirely borne by Tenant.

(c)                                  The inclusion of the improvements, facilities and services set forth in Subparagraph 4.2(a) shall not be deemed to impose any obligation upon Landlord to either have said improvements or facilities or to provide those services.

(d)                                 Tenant shall pay monthly in advance on the same day as the Base Rent is due Tenant’s Share of estimated Operating Expenses in the amount set forth in Paragraph 1.6. Landlord shall deliver to Tenant within ninety (90) days after the expiration of each calendar year a reasonably detailed statement showing Tenant’s Share of the actual Operating Expenses incurred during the preceding year. If Tenant’s estimated payments under this Paragraph 4(d) during the preceding year exceed Tenant’s Share as indicated on said statement, Tenant shall be credited the amount of such overpayment against Tenant’s Share of Operating Expenses next becoming due. If Tenant’s estimated payments under this Paragraph 4.2(d) during said preceding year were less than Tenant’s Share as indicated on said statement, Tenant shall pay to Landlord the amount of the deficiency within ten (10) days after delivery by Landlord to tenant of said statement. At any time Landlord may adjust the amount of the estimated Tenant’s Share of Operating Expenses to reflect Landlord’s estimate of such expenses for the year.

(e)                                  Notwithstanding anything contained herein to the contrary, the Controllable Operating Expenses (as hereinafter defined) payable by Tenant for each calendar year after 2000 shall not be more than the sum of (i) the aggregate amount of Controllable Operating Expenses for the year 2000 and (ii) the product obtained by multiplying (A) .15, times (B) the number of complete calendar years that have elapsed between January 1 of the year 2000 and January 1 of the year for which such calculation is being made, times (C) the aggregate amount of Controllable Operating Expenses for the year 2000. For purposes of this Lease, the term “Controllable Operating Expenses” shall mean all items of Operating Expenses which are within the reasonable control of Landlord; thus, excluding Real Property Taxes, insurance, utilities, and other costs beyond the reasonable control of Landlord. The limit on the increases in Controllable Operating Expenses shall continue during any renewal or extended Term, using the year 2000 as the base year to calculate the applicable limit.

(f)                                   After giving Landlord thirty (30) days’ prior written notice thereof, Tenant may inspect or audit Landlord’s records relating to Operating Expenses for any periods of time within one year before the audit or inspection; however, no audit or inspection shall extend to periods of time before the Commencement Date. If Tenant fails to object to the calculation of Operating Expenses on an annual Operating Expense statement within thirty (30) days after the statement has been delivered to Tenant, then Tenant shall have waived its right to object to the calculation of Operating Expenses for the year in question and the calculation of Operating Expenses set forth on such statement shall be final. Tenant’s audit or inspection shall be conducted only during business hours reasonably designated by Landlord. Tenant shall pay the cost of such audit or inspection, including $100 per hour of Landlord’s or the building manager’s employee time devoted to such inspection or audit, to reimburse Landlord for its overhead costs allocable to the inspection or audit, unless the total Operating Expenses charged to Tenant for the time period

5

in question is determined to be in error by more than five percent (5 %) in the aggregate, in which case Landlord shall pay the audit cost. Tenant may not conduct an inspection or have an audit performed more than once during any calendar year. If such inspection or audit reveals that an error was made in the Operating Expenses previously charged to Tenant, then Landlord shall refund to Tenant any overpayment of any such costs, or Tenant shall pay to Landlord any underpayment of any such costs, as the case may be, within thirty (30) days after notification thereof. Tenant shall maintain the results of each such audit or inspection confidential and shall not be permitted to use any third party to perform such audit or inspection, other than an independent firm of certified public accountants reasonably acceptable to Landlord which agrees with Landlord in writing to maintain the results of such audit or inspection confidential.

5.                                      Security Deposit. Tenant shall deposit with Landlord upon Tenant’s execution hereof the Security Deposit set forth in Paragraph 1.7 as security for Tenant’s faithful performance of Tenants obligations under this Lease. If Tenant fails to pay Base Rent or Additional Rent or otherwise defaults under this Lease (as defined in Paragraph 13.1), Landlord may use the Security Deposit for the payment of any amount due Landlord or to reimburse or compensate Landlord for any liability, cost, expense, loss or damage (including attorney’s fees) which Landlord may suffer or incur by reason thereof. Tenant shall on demand pay Landlord the amount so used or applied so as to restore the Security Deposit to the amount set forth in Paragraph 1.7. Landlord shall not be required to keep all or any part of the Security Deposit separate from its general accounts. Landlord shall, at the expiration or earlier termination of the term hereof and after Tenant has vacated the Premises, return to Tenant that portion of the Security Deposit not used or applied by Landlord. No part of the Security Deposit shall be considered to be held in trust, to bear interest, or to be prepayment for any monies to be paid by Tenant under this Lease.

6.                                      Use.

6.1                               Permitted Use. Tenant shall use and occupy the Premises only for the Permitted Use set forth in Paragraph 1.8. Tenant shall not commit any nuisance, permit the emission of any objectionable noise or odor, suffer any waste, or make any use of the Premises which is contrary to any law or ordinance, or which would invalidate any of Landlord’s insurance, or which would increase the premiums for any insurance carried by Landlord which is typically carried by landlords of properties comparable to the Industrial Center. Tenant shall not service, maintain or repair vehicles on the Premises, Building or Common Areas. Tenant shall not store foods, pallets, drums or any other materials outside the Premises.

Landlord acknowledges and agrees that Tenant will be using the Premises for the manufacture, storing and distribution of pharmaceutical and related materials (some of which may contain Hazardous Substances) in the ordinary course of Tenant’s business (collectively, “Tenant’s Products”). Nothing contained in this Lease shall be construed to prohibit Tenant from bringing Tenant’s Products upon the Premises; provided, however, that Tenant must comply with all Applicable Requirements in respect of Tenant’s Products. With the exception of Tenant’s Products, Tenant shall not, without the prior written consent of Landlord, generate, possess, store, use, transport, or dispose of a Hazardous Substance (i) that requires a permit from, or with respect to which a report, notice, registration or business plan is required to be filed with, any governmental authority, or (ii) with respect to which any Applicable Requirements require that a notice be given to persons entering or occupying the Premises or neighboring properties.

6.4                               Inspection; Compliance with Law. In addition to Landlord’s environmental monitoring and insurance program, the cost of which is included in Operating Expenses, Landlord and the holders of any mortgages, deeds of trust or ground leases on the Premises (“Lenders”) shall have the right to enter the Premises at any time in the case of an emergency, and otherwise at reasonable times, for the purpose of inspecting the condition of the Premises and for verifying compliance by Tenant with this Lease and all Applicable Requirements. Landlord shall be entitled to employ experts and/or consultants in connection therewith to advise Landlord with respect to Tenant’s installation, operation, use, monitoring, maintenance, or removal of any Hazardous Substance on or from the Premises. Any inspection of the Premises conducted by Landlord or Lenders (other than in the event of an emergency) shall be done in compliance with any applicable requirements of the federal Food and Drug Administration (the “FDA”) or any requirements imposed by Tenant in order to comply with requirements of the FDA. The cost and expenses of any such inspections shall be paid by the party requesting same unless a violation of Applicable Requirements exists or is imminent or the inspection is requested or ordered by a governmental authority.

Subject to Section 8.6, Tenant shall indemnify, defend, and hold harmless Landlord, its successors, assigns, agents, employees, contractors, partners, directors, officers and affiliates (collectively, the “Indemnified Parties) from and against all fines, suits, losses, costs, liabilities, claims, demands, actions and judgments of every kind or character (a) arising from Tenant’s failure to perform its covenants hereunder, (b) recovered from or asserted against any of the Indemnified Parties on account of any Loss (defined below) to the extent that any such Loss is caused by a Tenant Party or any other person entering upon the Premises under or with a Tenant Party’s express or implied invitation or permission, (c) arising from or out of the occupancy or use by a Tenant Party or arising from or

9

out of any occurrence in the Premises, or (d) suffered by, recovered from or asserted against any of the Indemnified Parties by a Tenant Party, regardless of whether Landlord’s negligence caused such loss or damage. However, such indemnification of the Indemnified Parties by Tenant shall not be applicable if such loss, damage, or injury is caused by the gross negligence or willful misconduct of Landlord or any of its duly authorized agents or employees. The provisions of this Paragraph 8.5 shall survive the termination of this Lease with respect to any claims or liability accruing prior to such termination.

8.6                               Exemption of Landlord from Liability. Landlord shall not be liable to Tenant or those claiming by, through, or under Tenant for any injury to or death of any person or persons or the damage to or theft, destruction, loss or loss of use of any property or inconvenience (a “Loss”) caused by casualty, theft, fire, third parties, or any other matter (including Losses arising through repair or alteration of any part of the Building, or failure to make repairs, or from any other cause), regardless of whether the negligence (other than gross negligence) of either party caused such Loss in whole or in part, Landlord and Tenant each waives any claim it might have against the other for any damage to or theft, destruction, loss, or loss of use of any property, to the extent the same is insured against under any insurance policy maintained by it that covers the Building, the Premises, Landlord’s or Tenant’s fixtures, personal property, leasehold improvements, or business, or is required to be insured against by the waiving party under the terms hereof, regardless of whether the negligence or fault of the other party caused such loss; however, Landlord’s waiver shall not apply to any deductible amounts maintained by Landlord under its insurance. Each party shall cause its insurance carrier to endorse all applicable policies waiving the carrier’s rights of recovery under subrogation or otherwise against the other party.

8.7                               Breach of Lease by Landlord. Nothing contained in Section 8.5 or Section 8.6 above shall be construed to limit the remedies for breach of contract which Tenant may have for breach of this Lease by Landlord (it being agreed, however, that such remedies shall in all events be subject to other applicable provisions of this Lease, including, without limitation, Section 16.4 hereof).

9.                                      Damage or Destruction.

9.1                               Termination Right. Tenant shall give Landlord immediate written notice of any damage to the Premises. Thereafter, Landlord shall send Tenant written notice (the “Estimated Time Notice”) of the estimated period of time, as determined by Landlord’s architect, that repair of such damage will substantially interfere with the conduct of Tenant’s business at the Premises. Subject to the provisions of Paragraph 9.2, if the damage to the Premises is such that, in the opinion of Landlord’s architect as set forth in the Estimated Time Notice, there will be substantial interference with the conduct by Tenant of its business at the Premises for a period exceeding ninety (90) consecutive days, then Tenant may terminate this Lease by sending Landlord written notice thereof within ten (10) days after Tenant receives the Estimated Time Notice (time being of the essence), which termination shall be effective thirty (30) days after delivery of such notice of termination to Landlord. If the Estimated Time Notice states that repair of damage will not interfere with the conduct of Tenant’s business at the Premises for more than ninety (90) consecutive days, but such repair does in fact interfere with the conduct of Tenant’s business at the Premises for a period in excess of ninety (90) days (excluding delays caused by events of force majeure), then Tenant may terminate this Lease by sending Landlord written notice thereof within ten (10) days after the expiration of such ninety (90) day period (time being of the essence), which termination shall be effective thirty (30) days after delivery of such notice of termination to Landlord. No such termination shall excuse the performance by Tenant of those covenants which under the terms hereof survive termination. Rent shall be abated in proportion to the degree of interference during the period that there is such substantial interference with the conduct of Tenant’s business at the Premises. Abatement of rent and Tenant’s right of termination pursuant to this provision shall be Tenant’s only remedies for failure of Landlord to keep in good order, condition and repair the foundations and exterior walls of the Building, Building roof, utility systems outside the Building, the Common Areas and HVAC.

9.2                               Damage Caused by Tenant. Tenant’s termination rights under Paragraph 9.1 shall not apply if the damage to the Premises or Building is the result of any act or omission of Tenant or of any of Tenant’s agents,

10

employees, customers, invitees or contractors (“Tenant Acts”). Any damage resulting from a Tenant Act shall be promptly repaired by Tenant. Landlord at its option may at Tenant’s expense repair any damage caused by Tenant Acts. Tenant shall continue to pay all rent and other sums due hereunder and shall be liable to Landlord for all damages that Landlord may sustain resulting from a Tenant Act.

10.                               Real Property Taxes.

10.1                        Payment of Real Property Taxes. Landlord shall pay the Real Property Taxes due and payable during the term of this Lease and, except as otherwise provided in Paragraph 10.3, any such amounts shall be included in the calculation of Operating Expenses in accordance with the provisions of Paragraph 4.2. The amount of Real Property Taxes included in Operating Expenses shall take into account fully any tax abatement in effect with respect to the Industrial Center, such that Tenant derives its proportionate share of the benefit of any such tax abatement.

10.2                        Real Property Tax Definition. As used herein, the term “Real Property Taxes” is any form of tax or assessment, general, special, ordinary or extraordinary, imposed or levied by any governmental authority or by any owners’ association upon the Industrial Center or any interest of Landlord in the Industrial Center. Real Property Taxes include (a) any tax or charge which replaces or is in addition to any of such above-described “Real Property Taxes,” (b) any charge or assessment imposed upon the Industrial Center by an owners’ association or similar entity, and (c) any fees, expenses or costs (including attorney’s fees, expert fees and the like) incurred by Landlord in protesting or contesting any assessments levied or any tax rate. Real Property Taxes for tax years commencing prior to, or extending beyond, the term of this Lease shall be prorated to coincide with the corresponding Commencement Date or Expiration Date.

10.3                        Additional Improvements. Operating Expenses shall not include Real Property Taxes attributable to improvements placed upon the Industrial Center by other tenants or by Landlord for the exclusive enjoyment of such other tenants. Notwithstanding Paragraph 10.1 hereof, Tenant shall, however, pay to Landlord at the time Operating Expenses are payable under Paragraph 4.2, the entirety of any increase in Real Property Taxes if assessed by reason of improvements placed upon the Premises by Tenant or at Tenant’s request.

10.4                        Joint Assessment. If the Building is not separately assessed, Real Property Taxes allocated to the Building shall be based upon the assessed value of the Building and the land associated with the Building relative to the total assessed value of all of the land and improvements included within the tax parcel assessed (it being agreed that Tenant shall be responsible for payment of Tenant’s Share of taxes allocated to the Building, as set forth in Section 1.5(b) of the Basic Provisions). In the absence of manifest error, Landlord’s allocation of Real Property Taxes to the Building shall be binding upon Landlord and Tenant.

10.5                        Tenant’s Property Taxes. Tenant shall pay prior to delinquency all taxes assessed against and levied upon Tenant’s improvements, fixtures, furnishings, equipment and all personal property of Tenant contained in the Premises or stored within the Industrial Center.

11.                               Utilities. Tenant shall pay directly for all utilities and services supplied to the Premises, including but not limited to electricity, HVAC, telephone, security, gas and cleaning of the Premises, together with any taxes thereon.

12.                               Assignment and Subletting.

12.1                        Landlord’s Consent Required.

(a)                                 Except as otherwise provided in Paragraph 12.1(c) below, Tenant shall not assign, transfer, mortgage or otherwise transfer or encumber (collectively, “assign”) or sublet all or any part of Tenant’s interest in this Lease or in the Premises without Landlord’s prior written consent, which consent shall not be unreasonably withheld. Relevant criteria in determining reasonableness of consent include, but are not limited to, credit history of a proposed

11

assignee or sublessee, references from prior landlords, any change or intensification of use of the Premises or the Common Areas and any limitations imposed by the Internal Revenue Code and the Regulations promulgated thereunder relating to Real Estate Investment Trusts. Any assignment or subletting shall not release Tenant from its obligations hereunder. Tenant shall not (i) sublet or assign or enter into other arrangements such that the amounts to be paid by the sublessee or assignee thereunder would be based, in whole or in part, on the income or profits derived by the business activities of the sublessee or assignee; (ii) sublet the Premises or assign this Lease to any person in which Landlord owns an interest, directly or indirectly (by applying constructive ownership rules set forth in Section 856(d)(5) of the Internal Revenue Code (the “Code”); or (iii) sublet the Premises or assign this Lease in any other manner which could cause any portion of the amounts received by Landlord pursuant to this Lease or any sublease to fail to qualify as “rents from real property” within the meaning of Section 856(d) of the Code, or which could cause any other income received by Landlord to fail to qualify as income described in Section 856(c)(2) of the Code. The requirements of this Section 12.1 shall apply to any further subleasing by any subtenant.

(b)                                 A change in the control of Tenant shall constitute an assignment requiring Landlord’s consent. The transfer, on a cumulative basis, of twenty-five percent (25%) or more of the voting or management control of Tenant shall constitute a change in control for this purpose.

(c)                                  Notwithstanding the provisions of Paragraph 12.1(a), Landlord agrees that during the twelve (12) month period after the Commencement Date, Tenant may assign this Lease, without obtaining the consent of Landlord, to a limited partnership (to be named PFab LP) in which the partners (general and limited) are entities owned or controlled by PharmaFab, Inc., Bruce K. Montgomery or Darlene Ryan (or a combination thereof). However, Tenant shall promptly notify Landlord of such assignment. No such assignment shall relieve Tenant of its obligations under this Lease or relieve Bruce K. Montgomery or Darlene Ryan of their obligations as guarantors of the obligations of Tenant under this Lease. Upon the request of Landlord, Tenant shall (i) cause the assignee to execute an instrument reasonably satisfactory to Landlord evidencing the assumption by such assignee of all of Tenant’s obligations under this Lease, and (ii) cause each guarantor of this Lease to execute a ratification of his or her guaranty.

12.2                        Rent Adjustment. If, as of the effective date of any permitted assignment or subletting the then remaining term of this Lease is less than three (3) years, Landlord may terminate this Lease as of the date of assignment or subletting subject to the performance by Tenant of those covenants which under the terms hereof survive termination.

13.                               Default; Remedies.

13.1                        Default. The occurrence of any one of the following events shall constitute an event of default on the part of Tenant (“Default”):

(a)                                 The abandonment of the Premises by Tenant;

(b)                                 Failure to pay any installment of Base Rent, Additional Rent or any other monies due and payable hereunder for a period of three (3) days after Landlord has delivered to Tenant written notice thereof; provided, however, that a Default shall immediately occur hereunder, without Landlord first having to give Tenant written notice, if Tenant is more than three (3) days delinquent in paying any Base Rent, Additional Rent or any other monies due under this Lease and Landlord has given Tenant written notice under this Paragraph 13.1(b) on more than one (1) occasion during the Term.

(c)                                  A general assignment by Tenant or any guarantor for the benefit of creditors;

(d)                                 The filing of a voluntary petition in bankruptcy by Tenant or any guarantor, the filing of a voluntary petition for an arrangement, the filing of a petition, voluntary or involuntary, for reorganization, or the filing of an involuntary petition by Tenant’s creditors or guarantors;

12

(e)                                  Receivership, attachment, of other judicial seizure of the Premises or all or substantially all of Tenant’s assets on the Premises;

(f)                                   Failure of Tenant to maintain insurance as required by Paragraph 8.2;

(g)                                  Any breach by Tenant of its covenants under Paragraph 6.2;

(h)                                 Failure in the performance of any of Tenant’s covenants, agreements or obligations hereunder (except those failures specified as events of Default in other Paragraphs of this Paragraph 13.1 which shall be governed by such other Paragraphs), which failure continues for 10 days after written notice thereof from Landlord to Tenant provided that, if Tenant has exercised reasonable diligence to cure such failure and such failure cannot be cured within such ten (10) day period despite reasonable diligence, Tenant shall not be in default under this subparagraph unless Tenant fails thereafter diligently and continuously to prosecute the cure to completion; and

(i)                                     The default of any guarantors of Tenant’s obligations hereunder under any guaranty of this Lease, or the attempted repudiation or revocation of any such guaranty.

13.2                        Remedies. In the event of any Default by Tenant, Landlord shall have the remedies set forth in the Addendum attached hereto entitled “Landlord’s Remedies in Event of Tenant Default”.

13.3                        Late Charges. Tenant hereby acknowledges that late payment by Tenant to Landlord of rent and other sums due hereunder will cause Landlord to incur costs not contemplated by this Lease, the exact amount of which will be extremely difficult to ascertain. Such costs include, but are not limited to, processing and accounting charges. Accordingly, if any installment of rent or other sum due from Tenant shall not be received by Landlord or Landlord’s designee within 10 days after such amount shall be due, then, without any requirement for notice to Tenant, Tenant shall pay to Landlord a late charge equal to 5% of such overdue amount. The parties hereby agree that such late charge represents a fair and reasonable estimate of the costs Landlord will incur by reason of late payment by Tenant. Acceptance of such late charge by Landlord shall in no event constitute a waiver of Tenant’s Default with respect to such overdue amount, nor prevent Landlord from exercising any of the other rights and remedies granted hereunder.

14.                               Condemnation. If the Premises or any portion thereof are taken under the power of eminent domain or sold under the threat of exercise of said power (all of which are herein called “condemnation”), this Lease shall terminate as to the part so taken as of the date the condemning authority takes title or possession, whichever first occurs. If more than ten percent (10%) of the floor area of the Premises, or more than twenty-five (25%) of the portion of the Common Areas designated for Tenant’s parking, is taken by condemnation, Tenant may, at Tenant’s option, to be exercised in writing within ten (10) days after Landlord shall have given Tenant written notice of such taking (or in the absence of such notice, within ten (10) days after the condemning authority shall have taken possession) terminate this Lease as of the date the condemning authority takes such possession. If Tenant does not terminate this Lease in accordance with the foregoing, this Lease shall remain in full force and effect as to the portion of the Premises remaining, except that the Base Rent shall be reduced in the same proportion as the rentable floor area of the Premises taken bears to the total rentable floor area of the Premises. No reduction of Base Rent shall occur if the condemnation does not apply to any portion of the Premises. Any award for the taking of all or any part of the Premises under the power of eminent domain or any payment made under threat of the exercise of such power shall be the property of Landlord, provided, however, that Tenant shall be entitled to any compensation, separately awarded to Tenant for Tenant’s relocation expenses and/or loss of Tenants trade fixtures. In the event that this Lease is not terminated by reason of such condemnation, Landlord shall to the extent of its net severance damages in the condemnation matter, repair any damage to the Premises caused by such condemnation authority. Tenant shall be responsible for the payment of any amount in excess of such net severance damages required to complete such repair.

13

15.                               Estoppel Certificate and Financial Statements.

15.1                        Estoppel Certificate. Each party (herein referred to as “Responding Party”) shall within 10 days after written notice from the other Party (the “Requesting Party”) execute, acknowledge and deliver to the Requesting Party, to the extent it can truthfully do so, an estoppel certificate in the form attached hereto, plus such additional information, confirmation a/or statements as be reasonably requested by the Requesting Party.

15.2                        Financial Statement. If Landlord desires to finance, refinance, or sell the Building, Industrial Center or any part thereof, Tenant and all Guarantors shall deliver to any potential lender or purchaser designated by Landlord such financial statements of Tenant and such Guarantors as may be reasonably required by such lender or purchaser, including but not limited to Tenant’s financial statements for the past 3 years. All such financial statements shall be received by Landlord and such lender or purchaser in confidence and shall be used only for the purposes herein set forth.

16.                               Additional Covenants and Provisions.

16.1                        Severability. The invalidity of any provision of this Lease, as determined by a court of competent jurisdiction, shall not affect the validity of any other provision hereof.

16.2                        Interest on Past-Due Obligations. Any monetary payment due Landlord hereunder not received by Landlord within 10 days following the date on which it was due shall bear interest from the date due at twelve percent (12%) per annum, but not exceeding the maximum rate allowed by law in addition to the late charge provided for in Paragraph 13.3.

16.3                        Time of Essence. Time is of the essence with respect to the performance of all obligations to be performed or observed by the Parties under this Lease.

16.4                        Landlord Liability. Tenant, its successors and assigns, shall not assert nor seek to enforce any claim for breach of this Lease against any of Landlord’s assets other than Landlord’s interest in the Industrial Center. Tenant agrees to look solely to such interest for the satisfaction of any liability or claim against Landlord under this Lease. In no event whatsoever shall Landlord (which term shall include, without limitation, any general or limited partner, trustees, beneficiaries, officers, directors, or stockholders of Landlord) ever be personally liable for any such liability.

16.5                        No Prior or Other Agreements. This Lease contains all agreements between the Parties with respect to any matter mentioned herein, and supersedes all oral, written prior or contemporaneous agreements or understandings.

16.6                        Notice Requirements. All notices required or permitted by this Lease shall be in writing and may be delivered in person (by hand or by messenger or courier service) or may be sent by regular, certified or registered mail or U.S. Postal Service Express Mail, with postage prepaid, or by facsimile transmission during normal business hours, and shall be deemed sufficiently given if served in a manner specified in the Paragraph 16.6. The addresses noted adjacent to a Party’s signature on this Lease shall be that Party’s address for delivery or mailing of notice purposes. Either Party may by written notice to the other specify a different address for notice purposes, except that upon Tenant’s taking possessing of the Premises, the Premises shall constitute Tenant’s address for the purpose of mailing or delivering notices to Tenant. A copy of all notices required or permitted to be given to Landlord hereunder shall be concurrently transmitted to such party or parties at such addresses as Landlord may from time to time hereafter designate by written notice to Tenant.

16.7                        Date of Notice. Any notice sent by registered or certified mail, return receipt requested, shall be deemed given on the date of delivery shown on the receipt card, or if no delivery date is shown, the postmark thereon. If sent by regular mail, the notice shall be deemed given 48 hours after the same is addressed as required herein and

14

mailed with postage prepaid. Notices delivered by United States Express Mail or overnight courier that guarantees next day delivery shall be deemed given 24 hours after delivery of the same to the United States Postal Service or courier. If any notice is transmitted by facsimile transmission or similar means, the same shall be deemed served or delivered upon telephone or facsimile confirmation of receipt of the transmission thereof, provided a copy is also delivered via hand or overnight delivery or certified mail. If notice is received on a Saturday or a Sunday or a legal holiday, it shall be deemed received on the next business day.

16.8                        Waivers. No waiver by Landlord or Tenant of a default by the other party shall be deemed a waiver of any subsequent default by such defaulting party or a waiver of any other term, covenant or condition hereof.

16.9                        Holdover. Tenant has no right to retain possession of the Premises or any part thereof beyond the expiration or earlier termination of this Lease. If Tenant holds over with the consent of Landlord: (a) the Base Rent payable shall be increased to one hundred fifty percent (150%) of the Base Rent applicable during the month immediately preceding such expiration or earlier termination; (b) Tenant’s right to possession shall terminate on thirty (30) days notice from Landlord and (c) all other terms and conditions of this Lease shall continue to apply. Nothing contained herein shall be construed as a consent by Landlord to any holding over by Tenant. Tenant shall indemnify, defend and hold Landlord harmless from and against any and all claims, demands, actions, losses, damages, obligations, costs and expenses, including, without limitation, attorneys’ fees incurred or suffered by Landlord by reason of Tenant’s failure to surrender the Premises on the expiration or earlier termination of this Lease in accordance with the provisions of this Lease.

16.10                 Cumulative Remedies. No remedy or election hereunder shall be deemed exclusive but shall, wherever possible, be cumulative with all other remedies in law or in equity.

16.11                 Binding Effect; Choice of Law. This Lease shall be binding upon the Parties, their personal representatives, successors and assigns and be governed by the laws of the State in which the Premises are located. Any litigation between the Parties hereto concerning this Lease shall be initiated in the county in which the Premises are located.

16.12                 Landlord. The covenants and obligations contained in this Lease on the part of Landlord are binding on Landlord, its successors and assigns, only during and in respect of their respective period of ownership of such interest in the Industrial Center. In the event of any transfer or transfers of such title to the Industrial Center, Landlord (and in case of any subsequent transfers or conveyances, the then grantor) shall be concurrently freed and relieved from and after the date of such transfer or conveyance, without any further instrument or agreement, of all liability with respect to the performance of any covenants or obligations on the part of Landlord contained in this Lease thereafter to be performed.

16.13                 Attorneys’ Fees and Other Costs. If any Party brings an action or proceeding to enforce the terms hereof or declare rights hereunder, the Prevailing Party (as hereafter defined) in any such proceeding shall be entitled to reasonable attorneys’ fees. The term “Prevailing Party” shall include, without limitation, a Party who substantially obtains or defeats the relief sought. Landlord shall be entitled to attorneys’ fees, costs and expenses incurred in preparation and service of notices of Default and consultations in connection therewith, whether or not a legal action is subsequently commenced in connection with such Default or resulting breach. Tenant shall reimburse Landlord on demand for all reasonable legal, engineering and other professional services expenses incurred by Landlord in connection with all requests by Tenant for consent or approval hereunder.

16.14                 Landlord’s Access; Showing Premises; Repairs. Landlord and Landlord’s agents shall have the right to enter the Premises at any time, in the case of an emergency, and otherwise at reasonable times upon reasonable notice for the purpose of showing the same to prospective purchasers, lenders, or tenants, and making such alterations, repairs, improvements or additions to the Premises or to the Building, as Landlord may reasonably deem necessary. Any inspection of the Premises conducted by Landlord or Landlord’s agents (other than in the event of an emergency)

15

shall be done in compliance with any applicable requirements of the FDA or any requirements imposed by Tenant in order to comply with requirements of the FDA. Landlord may at any time place on or about the Premises or Building any ordinary “For Sale” signs and Landlord may at any time during the last one hundred eighty (180) days of the term hereof place on or about the Premises any ordinary “For Lease” signs. All such activities of Landlord shall be without abatement of rent or liability to Tenant.

16.15                 Signs. Tenant shall not place any signs at or upon the exterior of the Premises or the Building, except that Tenant may, with Landlord’s prior written consent, install (but not on the roof) such signs as are reasonably required to advertise Tenant’s own business so long as such signs are in a location designated by Landlord and comply with sign ordinances and the sign age criteria established for the Industrial Center by Landlord. The sign age criteria of Landlord is attached hereto as Exhibit C.

16.16                 Termination: Merger. Unless specifically stated otherwise in writing by Landlord, the voluntary or other surrender of this Lease by Tenant, the mutual termination or cancellation hereof, or a termination hereof by Landlord for Default by Tenant, shall automatically terminate any sublease or lesser estate in the Premises; provided, however, Landlord shall, in the event of any such surrender, termination or cancellation, have the option to continue any one or all of any existing subtenancies. Landlord’s failure within ten (10) days following any such event to make a written election to the contrary by written notice to the holder of any such lesser interest, shall constitute Landlord’s election to have such event constitute the termination of such interest.

16.17                 Quiet Possession. Upon payment by Tenant of the Base Rent and Additional Rent for the Premises and the performance of all of the covenants, conditions and provisions on Tenant’s part to be observed and performed under this Lease, Tenant shall have quiet possession of the Premises for the entire term hereof subject to all of the provisions of this Lease.

16.18                 Subordination; Attornment; Non-Disturbance.

(a)                      Subordination. This Lease shall be subject and subordinate to any ground lease, mortgage, deed of trust, or other hypothecation or mortgage (collectively, “Mortgage”) now or hereafter placed by Landlord upon the real property of which the Premises are a part, to any and all advances made on the security thereof and to all renewals, modifications, consolidations, replacements and extensions thereof. Tenant agrees that any person holding any Mortgage shall have no duty, liability or obligation to perform any of the obligations of Landlord under this Lease. In the event of Landlord’s default with respect to any such obligation, Tenant will give any Lender, whose name and address have previously in writing been furnished Tenant, notice of a default by Landlord. Tenant may not exercise any remedies for default by Landlord unless and until Landlord and the Lender shall have received written notice of such default and a reasonable time (not less than sixty (60) days) shall thereafter have elapsed without the default having been cured. If any Lender shall elect to have this Lease superior to the lien of its Mortgage and shall give written notice thereof to Tenant, this Lease shall be deemed prior to such Mortgage. The provisions of a Mortgage relating to the disposition of condemnation and insurance proceeds shall prevail over any contrary provisions contained in this Lease.

(b)                      Attornment. Subject to the non-disturbance provisions of subparagraph C of this Paragraph 16.18, Tenant agrees to attorn to a Lender or any other party who acquires ownership of the Premises by reason of a foreclosure of a Mortgage. In the event of such foreclosure, such new owner shall not: (i) be liable for any act or omission of any prior landlord or with respect to events occurring prior to acquisition of ownership, (ii) be subject to any offsets or defenses which Tenant might have against any prior Landlord, or (iii) be liable for security deposits or be bound by prepayment of more than one month’s rent.

(c)                       Non-Disturbance. With respect to Mortgage entered into by Landlord after the execution of this Lease, Tenant’s subordination of this Lease shall be subject to receiving assurance (a “non-disturbance agreement”) from the Mortgage holder not disturbing Tenant’s possession of the Premises so long as this Lease is in full force and

16

effect and Tenant is not in default under this Lease.

(d)                       Self-Executing. The agreements contained in this Paragraph 16.18 shall be effective without the execution of any further documents; provided, however, that upon written request from Landlord or a Lender in connection with a sale, financing or refinancing of Premises, Tenant and Landlord shall execute such further writings as may be reasonably required to separately document any such subordination or non-subordination, attornment and/or non-disturbance agreement as is provided for herein. Landlord is hereby irrevocably vested with full power to subordinate this Lease to a Mortgage.

16.19                 Financing by Tenant. Landlord acknowledges and agrees that Tenant may grant a security interest in the personalty, furniture, trade fixtures and inventory owned by Tenant in the Premises to an institutional lender. Upon the grant of such security interest, Landlord shall, upon the request of Tenant, execute and deliver to Tenant a subordination agreement in the form of Exhibit D attached hereto.

16.20                 Rules and Regulations. Tenant agrees that it will abide by, and to cause its employees, suppliers, shippers, customers, tenants, contractors and invitees to abide by all reasonable rules and regulations (“Rules and Regulations”) which Landlord may make from time to time for the management, safety, care, and cleanliness of the Common Areas, the parking and unloading of vehicles and the preservation of good order, as well as for the convenience of other occupants or tenants of the Building and the Industrial Center and their invitees. Landlord shall not be responsible to Tenant for the non-compliance with said Rules and Regulations by other tenants of the Industrial Center; provided, however, that Landlord agrees to use reasonable efforts to attempt to enforce the Rules and Regulations on a uniform basis.

16.21                 Security Measures. Tenant acknowledges that the rental payable to Landlord hereunder does not include the cost of guard service or other security measures. Landlord has no obligations to provide same. Tenant assumes all responsibility for the protection of the Premises, Tenant, its agents and invitees and their property from the acts of third parties.

16.22                 Reservations. Landlord reserves the right to grant such easements that Landlord deems necessary and to cause the recordation of parcel maps, so long as such easements and maps do not reasonably interfere with the use of the Premises by Tenant. Tenant agrees to sign any documents reasonably requested by Landlord to effectuate any such easements or maps.

16.23                 Conflict. Any conflict between the printed provisions of this Lease and the typewritten or handwritten provisions shall be controlled by the typewritten or handwritten provisions.

16.24                 Offer. Preparation of this Lease by either Landlord or Tenant or Landlord’s agent or Tenant’s agent and submission of same to Tenant or Landlord shall not be deemed an offer to lease. This Lease is not intended to be binding until executed and delivered by all Parties hereto.

16.25                 Amendments. This Lease may be modified only in writing, signed by the parties in interest at the time of the modification.

16.26                 Multiple Parties. Except as otherwise expressly provided herein, if more than one person or entity is named herein as Tenant, the obligations of such persons shall be the joint and several responsibility of all persons or entities named herein as such Tenant.

16.27                 Authority. Each person signing on behalf of Landlord or Tenant warrants and represents that she or is authorized to execute and deliver this Lease and to make it a binding obligation of Landlord or Tenant.

Landlord’s Remedies Addendum In Event of Tenant Default

(State of Texas)

(a)                                 Upon any Default, Landlord may, in addition to all other rights and remedies afforded Landlord hereunder or by Applicable Requirements, take any of the follow actions:

(i)                                     Terminate this Lease by giving Tenant written notice thereof, in which event, Tenant shall pay to Landlord the sum of (A) all unpaid past due rent accrued hereunder through the date of termination, (B) all amounts due under paragraph (b) below, and (C) an amount equal to (1) the total rent that Tenant would have been required to pay for the remainder of the Term discounted to a present value at a per annum rate equal to the “Prime Rate” as published on the date this Lease is terminated by The Wall Street Journal, Southwest Edition, in its listing of “Money Rents”, minus (2) the then present fair rental value of the Premises for such period, as determined by Landlord in good faith, similarly discounted; or

(ii)                                  Terminate Tenant’s right to possess the Premises and change the door locks to the Premises without terminating this Lease, with or without notice thereof to Tenant, and without judicial proceedings, in which event Tenant shall pay to Landlord (A) all unpaid past due rent and other amounts accrued hereunder to the date of termination of possession, (B) all amounts due from time to time under paragraph (b) below, and (C) all rent and other sums required hereunder to be paid by Tenant during the remainder of the Term, diminished by any net sums thereafter received by Landlord through reletting the Premises during such period. Tenant shall not be entitled to the excess of any consideration obtained by reletting over the rent due hereunder. Reentry to Landlord in the Premises shall not affect Tenant’s obligations hereunder for the unexpired Term; rather, Landlord may, from time to time, bring action against Tenant to collect amounts due by Tenant, without the necessity of Landlord’s waiting until the expiration of the Term. Unless Landlord delivers written notice to Tenant expressly stating that it has elected to terminate this Lease, all actions taken by Landlord to exclude or dispossess Tenant of the Premises shall be deemed to be taken under this paragraph (a)(ii). If Landlord elects to proceed under this paragraph (a)(ii), it may at any time elect to terminate this Lease under paragraph (a)(i) above. Landlord and Tenant hereby confirm that the terms and provisions of this addendum supersedes Section 93.002 of the Texas Property Code to the extent of any conflict.

(b)                                 Tenant shall pay to Landlord all reasonable costs and expenses incurred by Landlord (including court costs and reasonable attorney’s fees and expenses) in (i) obtaining possession of the Premises, (ii) removing and storing Tenant’s or any other occupant’s property, (iii) renovating, repairing and altering the Premises for a new tenant or tenants, (iv) if Tenant is dispossessed of the Premises and this Lease is not terminated, reletting all or any part of the Premises (including brokerage commissions, reasonable cost of tenant finish work, and other costs incidental to such reletting), (v) performing Tenant’s obligations which Tenant failed to perform, and (vi) enforcing, or advising Landlord of its rights, remedies, and recourses. Landlord’s acceptance of rent following the occurrence of a Default shall not waive Landlord’s rights regarding such Default. Landlord’s receipt of rent with knowledge of any Default by Tenant hereunder shall not be a waiver of such Default, and no waiver by Landlord of any provision of this Lease shall be deemed to have been made unless set forth in writing and signed by Landlord. No waiver by Landlord of any violation or breach of any of the terms contained herein shall waive Landlord’s rights regarding any future violation of such term or violation of any other term. If Landlord repossesses the Premises pursuant to the authority herein granted, then Landlord shall have the right to (A) keep in place and use or (B) remove and store, at Tenant’s expense, all of the furniture, fixtures, equipment or other property, deemed abandoned by Tenant in the Premises, including that which is owned by or leased to Tenant at all times before any foreclosure thereon by Landlord or repossession thereof by any lessor thereof or third party having a lien thereon. Landlord may relinquish possession of all or any portion of such furniture, fixtures, equipment and other property to any person (a “Claimant”) who presents to Landlord a copy of any instrument represented by Claimant to have been executed by Tenant (or any predecessor of Tenant) granting Claimant the right under various circumstances to take possession of such furniture, fixtures, equipment or other property, without the necessity on the part of Landlord to inquire into the authenticity or legality of the instrument. The rights

19

of Landlord herein stated are in addition to any and all other rights that Landlord has or may hereafter have at law or in equity, and Tenant agrees that the rights herein granted Landlord are commercially reasonable.

Tenant Improvements Addendum

1.                                      Landlord shall construct the leasehold improvements in the Premises (the “Leasehold Improvements”) in substantial accordance with plans and specifications (the “Plans”) which have been mutually approved in writing by Landlord and Tenant. Landlord and Tenant will endeavor to agree upon the Final Plans not later than June 10, 1999. Tenant shall be responsible for the costs of preparing the Final Plans and any other architectural and design costs in respect of the Leasehold Improvements (which costs may be paid from the Tenant Allowance, as hereinafter defined).

2.                                      After the Plans have been approved by Landlord and Tenant, Landlord shall competitively bid the job to a minimum of three (3) qualified general contractors reasonably acceptable to Landlord and Tenant. Landlord shall contract with the lowest qualified bidder, or such other bidder as is agreed upon by Landlord and Tenant (the “Contractor”), to construct the Leasehold Improvements in the Premises; provided, however, that if the lowest bid (or such other bid agreed upon by Landlord and Tenant) is more than Nine Hundred Thousand Dollars ($900,000), Landlord and Tenant shall revise the Plans in such a manner that the cost of constructing the Leasehold Improvements reflected in the Plans, as revised, is not more than Nine Hundred Thousand Dollars ($900,000). Landlord shall cause the Contractor to construct the Leasehold Improvements in substantial accordance with the approved Plans and in a good and workmanlike manner utilizing all new materials. The contract with the Contractor shall obligate the Contractor to obtain necessary permits and approvals from local governmental authorities in respect of the construction of the Leasehold Improvements and to construct the Leasehold Improvements in accordance with all applicable laws, codes and regulations (it being expressly agreed that it shall be the responsibility of Tenant to cause any requirements of the FDA to be incorporated into the approved Plans). During the construction period, Tenant shall have access to the Premises during reasonable times to observe the progress and quality of the work; provided, however, that Tenant shall at all time when visiting the Premises comply with Contractor’s safety requirements. Any changes which the Tenant may request during the construction of Leasehold Improvements shall be submitted to the Landlord in written form, and change orders shall be subject to the written approval of both Landlord and Tenant. Thereupon, Landlord shall prepare a written change order for Tenant’s review and approval, which, when signed by Tenant and Landlord, shall authorize Landlord to make such change in the Leasehold Improvements.

3.                                      The Leasehold Improvements shall be deemed to be “substantially complete”and ready for delivery to Tenant at such time as a certificate of occupancy for the Premises is secured from the City of Grand Prairie. At such time as the Leasehold Improvements are substantially complete, Landlord, Tenant and Contractor shall walk the Premises for the purpose of preparing a “punch list” of items needing correction. Thereafter, the architect for construction of the Leasehold Improvements shall issue a certificate of substantial completion to which the “punch list” shall be attached. Landlord shall cause the Contractor to correct or complete the items on the “punch list” as soon as reasonably practicable, but in no event later than thirty (30) days after the date upon which the Leasehold Improvements are substantially complete.

4.                                      Tenant shall be responsible for the payment of all costs associated with the construction of the Leasehold Improvements, including, but not limited to, the following: (a) all costs, including professional fees, of the architect and all other design and planning costs; (b) the costs of labor and material associated with the construction of the Leasehold Improvements; and (c) a fee to Trammell Crow Dallas Fort Worth equal to four percent (4%) of the sum of all design, planning and construction costs associated with the construction of the Leasehold Improvements. It is understood and agreed that the Tenant Allowance, as hereinafter defined, may be used to pay the costs described in clauses (a), (b) and (c) of the preceding sentence.

21

5.                                      Notwithstanding anything to the contrary contained herein, Landlord grants to Tenant an allowance (the “Tenant Allowance”) in the amount of Seven Hundred Ninety-Two Thousand Dollars ($792,000) to be applied to the cost of the Leasehold Improvements and other costs described in Paragraph 4 above. In the event that the bid for the Leasehold Improvements exceeds the Tenant Allowance, Tenant shall prepay to Landlord the amount of such excess prior to the time Landlord enters into the construction contract with Contractor, it being agreed that the Tenant Allowance shall be advanced before such funds deposited by Tenant are used to pay for construction of the Leasehold Improvements. If the cost of constructing the Leasehold Improvements is less than the Tenant Allowance, Tenant may, within the twelve (12) month period after the Commencement Date, apply the unused portion of the Tenant Allowance towards the cost of additional construction in the Premises or an upgrade of the tenant finish work in the Premises. In the event that any portion of the Tenant Allowance remains unused upon the expiration of the twelve (12) month period after the Commencement Date, Landlord shall have no obligation to pay such unused portion to Tenant or otherwise allow Tenant the benefit thereof.

6.                                      Tenant shall cooperate with the Contractor to promote the efficient and expeditious completion of the Leasehold Improvements. Tenant agrees that in the event of default in payment hereunder, including, but not limited to, those payments due under Paragraph 5 above, Landlord, in addition to any and all other remedies at law or in equity, shall have the same rights and remedies against Tenant as in the event of default in payment of rent under the Lease.

7.                                      It is understood and agreed that any delay in construction of the Leasehold Improvements caused by Tenant shall not operate to delay the Commencement Date. Any of the following shall constitute a delay caused by Tenant: (a) Tenant’s failure to have preliminary plans prepared or Tenant’s failure to approve the plans in a timely manner; (b) any delay resulting from Tenant’s changes in the Plans; (c) any delay resulting from Tenant’s request for materials, finishes or installations which are not readily available; or (d) any delay in the construction of the Leasehold Improvements otherwise caused by Tenant.

Option To Extend Addendum

This Option To Extend Addendum is a part of the Lease dated June 29, 1999 by and between WALSTIB, L.P., a Delaware limited partnership (“Landlord”) and PharmaFab, Inc., a Texas corporation (“Tenant”) for the premises commonly known as 360 Riverside Business Center (Building B).

1.                                      Option to Extend.  Landlord hereby grants to Tenant the option to extend the term of this Lease for the following periods (“Option Periods”) commencing when the prior term expires:

Months 85 — 145 “Period One”

Months 145 — 205 “Period Two”

2.                                      Exercise Dates.  For purposes of Paragraph 5 of this Addendum:

(a)            the Earliest Exercise Date is 12 months prior to the date that the applicable Option Period would commence; and

(b)             the Last Exercise Date is 9 months prior to the date that the applicable Option Period would commence.

3.                                      Monthly Base Rent.  The monthly Base Rent for each month of an Option Period shall be the amount calculated in accordance with the alternative selected below (“Rent Adjustment Alternative”).

x Market rent (“Market Rent Adjustment”)

4.                                       Conditions to Exercise of Option.  Tenant’s right to extend is conditioned upon and subject to each of the following:

(a)            In order to exercise an option to extend, Tenant must give written notice of such election to Landlord and Landlord must receive the same by the Last Exercise Date but not prior to the Earliest Exercise Date. If proper notification of the exercise of an option is not given and/or received, such option shall automatically expire. Options (if there are more than one) may only be exercised consecutively. Failure to exercise an option terminates that option and all subsequent options. Tenant acknowledges that because of the importance to Landlord of knowing no later than the Last Exercise Date whether or not Tenant will exercise the option, the failure of Tenant to notify Landlord by the Last Exercise Date will conclusively be presumed an election by Tenant not to exercise the option.

(b)              Tenant shall have no right to exercise an option (i) if Tenant is in Default, or (ii) if during the twelve (12) month period immediately preceding the exercise of the option, three (3) or more Defaults have occurred which were not cured within any applicable notice or grace period. The period of time within which an option may be exercised shall not be extended or enlarged by reason of Tenant’s inability to exercise an option because of the provisions of this paragraph.

(c)               All of the terms and conditions of this Lease except where specifically modified by this Addendum shall apply.

23

(d) The options are personal to Tenant, cannot be assigned or exercised by anyone other than Tenant and only while Tenant is in full possession of the Premises and without the intention of thereafter assigning or subletting. For purposes of the preceding sentence only, the term “Tenant” shall include any entity to which Tenant assigns the Lease pursuant to Section 12.1(c) of the Lease.

5.             Calculation of Rent Adjustment

(a) Market Rent Adjustment. Four months prior to the commencement of each Option Period, if the selected Rent Adjustment Alternative is the Market Rent Adjustment, the Parties shall negotiate in good faith to determine the Base Rent for the Option Period. If agreement cannot be reached within 30 days, then Landlord and Tenant shall each, no later then 90 days prior to the commencement of the Option Period, make a reasonable determination of the fair market rental for the Premises for the Option Period and submit such determination, in writing, to arbitration in accordance with the following provisions:

(i)           No later than 90 days prior to the commencement of the Option Period, Landlord and Tenant shall each select an industrial leasing broker to act as an arbitrator. The two arbitrators so appointed shall, no later then 75 days prior to the commencement of the Option Period, select a third mutually acceptable industrial leasing broker to act as a third arbitrator.

(ii)          The three arbitrators, acting by a majority, shall no later then 75 days prior to the commencement of the Option Period, determine the actual fair market rental for the Premises for the Option Period. The decision of a majority of the arbitrators shall be binding on the parties. The fair market rental determination of Landlord or Tenant which is closest to the fair market rental as determined by the arbitrators shall be the Base Rent for the Option Period.

(iii)        If either of the parties fails to appoint an arbitrator within the period required by this Addendum, the arbitrator timely appointed shall determine the Base Rent for the Option Period.

(iv)         The entire cost of such arbitration shall be paid by the party whose fair market rental submission is not selected.

GUARANTY OF LEASE

WHEREAS, WALSTIB, L.P., a Delaware limited partnership (“Landlord”), and PharmaFab, Inc., a Texas corporation (“Tenant”) are about to execute a lease (“Lease”) dated June 29 1999, for the premises commonly known as 360 Riverside Business Center (Building B).

WHEREAS, Bruce K. Montgomery and Darlene Ryan (each a “Guarantor”) have a financial interest in Tenant;

WHEREAS, Landlord would not execute the Lease if Guarantor did not execute and deliver to Landlord this Guaranty of Lease.

NOW THEREFORE, in consideration of the execution of the foregoing Lease by Landlord and as a material inducement to Landlord to execute the Lease:

1.          Guarantor hereby jointly, severally, unconditionally and irrevocably guarantee the prompt payment by Tenant of all rents and all other sums payable by Tenant under the Lease and the faithful and prompt performance by Tenant of each and every one of the terms, conditions and covenants of the Lease to be kept and performed by Tenant.

2.          The terms of the Lease may, without the consent of or notice to Guarantor, be modified by Landlord and Tenant or by a course of conduct and this Guaranty shall guarantee the performance of said Lease as so modified. The Lease may be assigned by Landlord or any assignee of Landlord without consent or notice to Guarantor.

3.          This Guaranty shall not be released, modified or affected by the failure or delay on the part of Landlord to enforce any of the rights or remedies of the Landlord under the Lease, whether pursuant to the terms thereof or at law or in equity.

4.          No notice of default need be given to Guarantor. The guaranty of the undersigned is a continuing guaranty under which Landlord may proceed immediately against Tenant and/or against any Guarantor (or each Guarantor) following any breach or default by Tenant or for the enforcement of any rights which Landlord may have against Tenant under the terms of the Lease or at law or in equity.

5.          Landlord shall have the right to proceed against any Guarantor (or each Guarantor) hereunder following any breach or default by Tenant without first proceeding against Tenant and without previous notice to or demand upon either Tenant or any Guarantor.

6.          Each Guarantor hereby waives (a) notice of acceptance of this Guaranty, (b) demand of payment, presentation and protest, (c) any right to require the Landlord to proceed against the Tenant or any other Guarantor or any other person or entity liable to Landlord, (d) any right to require Landlord to apply to any default any security deposit or other security it may hold under the Lease, (e) any right to require Landlord to proceed under any other remedy Landlord may have before proceeding against Guarantor and (f) any right of subrogation.

7.          Each Guarantor does hereby subrogate all existing or future indebtedness of Tenant to such Guarantor to the obligations owed to Landlord under the Lease and this Guaranty.

8.          If a Guarantor is married, such Guarantor expressly agrees that recourse may be had against his or her separate property for all of the obligations hereunder. If there is more than one Guarantor, the obligations of each Guarantor hereunder shall be joint and several.

9.          The obligations of Tenant under the Lease to execute and deliver estoppel certificates and financial

27

statements shall be deemed to also require each Guarantor hereunder to do and provide the same.

10.    The term “Landlord” refers to and means the Landlord named in the Lease and also Landlord’s successors and assigns. So long as Landlord’s interest in the Lease, the leased premises or the rents, issues and profits therefrom, are subject to any mortgage or deed of trust or assignment for security, no acquisition by Guarantor of the Landlord’s interest shall affect the continuing obligation of Guarantor under this Guaranty which shall nevertheless continue in full force and effect for the benefit of the mortgagee, beneficiary, trustee or assignee under such mortgage, deed of trust or assignment and their successors and assigns.

11.    The term “Tenant” refers to and means the Tenant named in the Lease and also Tenant’s successors and assigns.

12.    In the event any action be brought by said Landlord against Guarantor hereunder to enforce the obligation of Guarantor hereunder, the unsuccessful party in such action shall pay to the prevailing party therein a reasonable attorney’s fee which shall be fixed by the court.

13.     After three (3) years, provided Tenant has not had an uncured Default as described in the Lease, the aggregate liability of the Guarantors hereunder shall be limited to the sum of $380,000.00 on a joint and several basis (i.e. the liability of Bruce K. Montgomery hereunder shall be limited to $380,000, and the liablity of Darlene Ryan hereunder shall be limited to $3 80,000, but the maximum aggregate amount Landlord can recover from the Guarantors under this Guranty shall be limited to a total of $380,000). If no uncured Default has occurred under the Lease at the expiration of the fifth (5th) year of Tenant’s occupancy, this Guaranty shall terminate. It is agreed that if a Default occurs under the Lease which continues beyond the expiration of any applicable grace or cure period, Landlord may condition its acceptance of any cure of such Default upon keeping this Guaranty in effect.

Executed on the 10th day of June, 1999.

RECITALS

A.                                    Landlord and PharmaFab, Inc., a Texas corporation (“PharmaFab”), entered into that certain Commercial Lease Agreement dated on or about June 29, 1999, and having a Commencement Date as of October 25, 1999 (as same may have been amended and assigned, the “Lease”) regarding certain premises (the “Premises”) located at 360 Riverside Business Center in the City of Grand Prairie, Tarrant County, Texas, as more particularly described in the Lease.

B.                                    Pursuant to that certain Assignment of Lease dated on or about June 29, 1999, to be effective as of July 1, 1999, PharmaFab assigned its right, title and interest in the Lease to Tenant.

D.                                    Landlord and Tenant have agreed to amend the Lease as hereinafter set forth, and Darlene M. Ryan has agreed to execute a new guaranty of Tenant’s obligations under the Lease as hereinafter set forth.

NOW, THEREFORE, in consideration of the premises, Landlord and Tenant agree as follows:

1.                                      Defined Terms. All capitalized terms not defined herein shall have the meanings set forth for such terms in the Lease.

2.                                      Expansion of Premises. Landlord and Tenant agree that the Premises shall be expanded to include the space comprised of approximately 50,000 rentable square feet in Building A of the Industrial Center that is denoted on Exhibit A attached hereto and made a part hereof (and herein referred to) as the “Expansion Space”. Tenant acknowledges that Tenant has inspected the Expansion Space and agrees to accept the Expansion Space in “as is” condition.

5.                                      Adjustment in Tenant’s Share. As used in the Lease, the term “Building” shall refer to Building A and Building B. Landlord and Tenant agree that, as a result of adding the Expansion Space to the Premises, Tenant’s Share is as follows:

6.                                          Refurbishment Allowance. On December 1, 2005, Landlord shall provide to Tenant an allowance (the “Refurbishment Allowance”) of Two Hundred Fifty Thousand Dollars ($250,000) to be used by Tenant to design and construct improvements in the Premises; provided, however, that Landlord shall have no obligation to provide the Refurbishment Allowance if at such time (a) Tenant is the subject of a bankruptcy proceeding or any other insolvency proceeding, or (b) Tenant is in Default, or any circumstance exists which, with the giving of notice or the passage of time, or both, would constitute a Default. All improvements constructed with the Refurbishment Allowance shall be subject to the provisions of the Lease governing alterations to the Premises, and, unless waived in writing by Landlord, Trammell Crow Dallas Fort Worth (or its designee) shall serve as the construction manager for such improvements. The Refurbishment Allowance shall be used only for payment of the following: (i) costs, including professional fees, of the architect and other design and planning costs in connection with tenant improvements constructed in the Premises; (ii) the costs of labor and material associated with the construction of the tenant improvements in the Premises; and (iii) a fee equal to four percent (4%) of the sum of all design, planning and construction costs associated with the construction of the tenant improvements in the Premises, unless Landlord has waived in writing the requirement that Trammell Crow Dallas Fort Worth (or its designee) serve as construction manager, in which event no fee shall be owed. Landlord shall have the right to require, as a condition to any disbursement of any portion of the Refurbishment Allowance requested by Tenant, that Tenant provide Landlord copies of invoices and/or similar evidence that the requested disbursement is for one of the purposes set forth in the foregoing clauses (i), (ii) or (iii). In no event shall Landlord have any obligation to make any disbursement of the Refurbishment Allowance requested after May 1, 2006, it being agreed that after such date any unused portion of the Refurbishment Allowance shall be deemed forfeited by Tenant. Each payment of the Refurbishment Allowance shall be made within thirty (30) days after Landlord

has received a request therefor together with all other documents reasonably required by Landlord.

7.                                      Right of First Offer. Tenant shall have a right of first offer with respect to the space in Building A shown on Exhibit B attached hereto and made a part hereof (the “Offered Space”), under the following terms and conditions:

(a)                                 Subject to the provisions of Section 7(d) below, if at any time during the term of the Lease any lease for any portion of the Offered Space shall expire and if Landlord intends to market the Offered Space to prospects for lease with third parties (a “Proposed Tenant”) other than the tenant then occupying such space (or its affiliates), Landlord shall first allow Tenant the right to include the Offered Space within the Premises.

(b)                                 Such offer shall be made by Landlord to Tenant in a written notice (hereinafter called the “Offer Notice”) which notice shall designate the space being offered and shall specify the terms for such Offered Space that Landlord intends to submit to prospective tenants in an effort to market the Offered Space. Tenant may accept the offer set forth in the Offer Notice by delivering to Landlord an unconditional acceptance (hereinafter called “Tenant’s Notice”) of such offer within five (5) business days after delivery by Landlord of the Offer Notice to Tenant. Time shall be of the essence with respect to the giving of Tenant’s Notice. If Tenant does not accept (or fails to timely accept) an offer made by Landlord pursuant to the provisions hereof with respect to the Offered Space designated in the Offer Notice, Landlord shall be under no further obligation whatsoever respect to such space. In order to send the Offer Notice, Landlord does not need to have negotiated a lease with any particular Proposed Tenant but may merely have determined on what basis it will market the Offered Space to Proposed Tenants. Tenant must make its decision with respect to the Offered Space as long as it has received a description of such material economic terms.

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

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

(e)                                  Tenant shall not have the benefit of the foregoing right of first offer if Tenant is in Default at the time the Offer Notice is to be sent, or if at such time any

3

circumstance exists which, with the giving of notice or the passage of time, or both, would constitute a Default. The period of time Tenant’s right of first offer may be exercised shall not be extended or enlarged by reason of Tenant’s inability to exercise such right because of the provisions of this paragraph.

8.                                      Option to Extend. The addendum to the Lease captioned “Option to Extend Addendum” is hereby deleted in its entirety. Landlord hereby grants to Tenant the options to extend the term of this Lease for the periods (the “Option Periods”) (1) from December 1, 2010 to November 30, 2015, and (2) from December 1, 2015 to November 30, 2020, under the following terms and conditions.

(a)                                 In order to exercise an option to extend, Tenant must give written notice of such election to Landlord and Landlord must receive the same by no later than twenty four (24) months prior to the date (the “Last Exercise Date”) that the applicable Option Period would commence, but not earlier than thirty (30) months prior to the date that the applicable Option Period would commence. If proper notification of the exercise of an option is not given and/or received, such option shall automatically expire. The renewal options may only be exercised consecutively. Failure to exercise an option terminates that option and all subsequent options. Tenant acknowledges that because of the importance to Landlord of knowing no later than the Last Exercise Date whether or not Tenant will exercise the option, the failure of Tenant to notify Landlord by the Last Exercise Date will conclusively be presumed an election by Tenant not to exercise the option. Upon the exercise of an option to extend, both parties shall execute an amendment to the Lease evidencing the renewal thereof and setting forth the new Base Rent (as determined pursuant to Section 8(c) below) no later than eighteen (18) months prior to the date that the applicable Option Period would commence.

(b)                                 Tenant shall have no right to exercise an option (i) if Tenant is in Default. or (ii) if during the twelve (12) month period immediately preceding the exercise of the option, three (3) or more Defaults have occurred which were not cured within any applicable notice or grace period. The period of time within which an option may be exercised shall not be extended or enlarged by reason of Tenant’s inability to exercise an option because of the provisions of this paragraph.

(c)                                  If an option to extend is exercised, all of the terms and conditions of this Lease shall apply, except that (i) Landlord shall not be required to grant any allowance or perform any tenant improvement work in the Premises, and (ii) for each Option Period, Base Rent shall be adjusted to equal fair market rent. After an option to renew is exercised, Landlord and Tenant shall negotiate in good faith to determine the Base Rent for the applicable Option Period. If agreement cannot be reached within thirty (30) days, then Landlord and Tenant shall each, no later than sixty (60) days after the date of exercise of the option, make a reasonable determination of the fair market rental for the Premises for the applicable Option Period and submit such determination, in writing, to arbitration in accordance with the following provisions:

4

(i)                                     No later than ninety (90) days after the option to renew is exercised, Landlord and Tenant shall each select an industrial leasing broker to act as an arbitrator. The two arbitrators so appointed shall, no later then one hundred twenty (120) days after the option to renew is exercised, select a third mutually acceptable industrial leasing broker to act as a third arbitrator.

(ii)                                  The three arbitrators, acting by a majority, shall no later then one hundred fifty (150) days after the option to renew is exercised, determine the actual fair market rental for the Premises for the Option Period. The decision of a majority of the arbitrators shall be binding on the parties. The fair market rental determination of Landlord or Tenant which is closest to the fair market rental as determined by the arbitrators shall be the Base Rent for the Option Period.

(iii)                               If either of the parties fails to appoint an arbitrator within the period required by this Addendum, the arbitrator timely appointed shall determine the Base Rent for the Option Period.

(iv)                              The entire cost of such arbitration shall be paid by the party whose fair market rental submission is not selected.

(d)                                 The renewal options set forth herein are personal to Tenant, cannot be assigned or exercised by anyone other than Tenant and only while Tenant is in full possession of the Premises and without the intention of thereafter assigning or subletting.

9.                                      Guaranty. Concurrently with the execution hereof, Tenant shall cause Darlene M. Ryan to execute and deliver to Landlord a guaranty in the form of Exhibit C attached hereto and made a part hereof, which shall supersede the Original Guaranty.

10.                               Commission Agreement. Attached hereto as Exhibit D is a copy of the Commission Agreement (herein so called) executed between Landlord, as “Owner,” and Fobare Commercial, as “Agent,” in connection with the Lease. The Commission Agreement shall remain in full force and effect, except that in connection with this Amendment (and this Amendment only) the compensation paid to Agent shall be as set forth on Exhibit E attached hereto. The Commission Agreement, as modified with respect to this Amendment only in the manner described on Exhibit E, shall be deemed included as a provision of this Lease in compliance with Section 62.022 of the Texas Property Code.

11.                               Counterparts. The parties may execute this Amendment in any number of counterparts with the same effect as if all parties to this Amendment had signed the same document.

12.                               Governing Law. The Lease, as amended hereby, shall be governed and construed in accordance with the laws of the State of Texas.

13.                               Continued Effect. The Lease, as amended hereby, is ratified and confirmed and shall continue in full force and effect.

IN WITNESS WHEREOF, Landlord and Tenant have duly executed this Amendment to be effective as of the day and year first above written.

Exhibit C

GUARANTY OF LEASE

This Guaranty of Lease (this “Guaranty”) is made to be effective as of September 1, 2002, by DARLENE M. RYAN (“Guarantor”) for the benefit of WALSTIB, L.P., a Delaware limited partnership (“Landlord”).

A.                                    Landlord and PharmaFab, Inc., a Texas corporation (“PharmaFab”), entered into that certain Commercial Lease Agreement dated on or about June 29, 1999, and having a Commencement Date as of October 25, 1999 (as same may have been amended and assigned, the “Original Lease”) regarding certain premises located at 360 Riverside Business Center in the City of Grand Prairie, Tarrant County, Texas, as more particularly described in the Original Lease.

B.                                    Pursuant to that certain Assignment of Lease dated on or about June 29, 1999, to be effective as of July 1, 1999, PharmaFab assigned its right, title and interest in the Original Lease to PFab, LP, a Texas limited partnership (“Tenant”).

C.                                    Pursuant to that certain Guaranty of Lease (the “Original Guaranty”), Bruce K. Montgomery (“Montgomery”) and Guarantor guaranteed the obligations of Tenant under the Original Lease, subject to certain limitations set forth in said Original Guaranty.

D.                                    Landlord would not have executed the Original Lease if Montgomery and Guarantor had not executed and delivered the Original Guaranty to Landlord.

E.                                     Landlord and Tenant have entered into that certain First Amendment to Lease of even date herewith (the “First Amendment”) providing for, among other things, the expansion of the premises demised by Landlord to Tenant (the Original Lease, as amended by the First Amendment, being herein referred to as the “Lease”).

F.                                      In connection with the First Amendment, Guarantor (who owns an interest in Tenant) has agreed to execute and deliver to Landlord, and Landlord has agreed to accept, this Guaranty as a replacement of the Original Guaranty, it being understood that Landlord is not willing to execute the First Amendment if Guarantor does not execute and deliver this Guaranty to Landlord.

NOW THEREFORE, in consideration of the execution of the First Amendment by Landlord and as a material inducement to Landlord to execute the First Amendment:

1.                                      Guarantor hereby unconditionally and irrevocably guarantees the prompt payment by Tenant of all rents and all other sums payable by Tenant under the Lease and the faithful and prompt performance by Tenant of each and every one of the terms, conditions and covenants of the Lease to be kept and performed by Tenant.

2.                                      The terms of the Lease may, without the consent of or notice to Guarantor, be modified by Landlord and Tenant or by a course of conduct and this Guaranty shall guarantee the

9

performance of said Lease as so modified. The Lease may be assigned by Landlord or any assignee of Landlord without consent or notice to Guarantor.

3.                                      This Guaranty shall not be released, modified or affected by the failure or delay on the part of Landlord to enforce any of the rights or remedies of the Landlord under the Lease, whether pursuant to the terms thereof or at law or in equity.

4.                                      No notice of default need be given to Guarantor. The guaranty of the undersigned is a continuing guaranty under which Landlord may proceed immediately against Tenant and/or against Guarantor following any breach or default by Tenant or for the enforcement of any rights which Landlord may have against Tenant under the terms of the Lease or at law or in equity.

5.                                      Landlord shall have the right to proceed against Guarantor hereunder following any breach or default by Tenant without first proceeding against Tenant and without previous notice to or demand upon either Tenant or Guarantor.

6.                                      Guarantor hereby waives (a) notice of acceptance of this Guaranty, (b) demand of payment, presentation and protest, (c) any right to require Landlord to proceed against Tenant or any other person or entity liable to Landlord, (d) any right to require Landlord to apply to any default any security deposit or other security it may hold under the Lease, (e) any right to require Landlord to proceed under any other remedy Landlord may have before proceeding against Guarantor, and (f) any right of subrogation.

7.                                      Guarantor does hereby subrogate all existing or future indebtedness of Tenant to such Guarantor to the obligations owed to Landlord under the Lease and this Guaranty.

8.                                      If a Guarantor is married, such Guarantor expressly agrees that recourse may be had against his or her separate property for all of the obligations hereunder.

9.                                      The obligations of Tenant under the Lease to execute and deliver estoppel certificates and financial statements shall be deemed to also require Guarantor to do and provide the same.

10.                               The term “Landlord” refers to and means the Landlord named in the Lease and also Landlord’s successors and assigns. So long as Landlord’s interest in the Lease, the leased premises or the rents, issues and profits therefrom, are subject to any mortgage or deed of trust or assignment for security, no acquisition by Guarantor of the Landlord’s interest shall affect the continuing obligation of Guarantor under this Guaranty which shall nevertheless continue in full force and effect for the benefit of the mortgagee, beneficiary, trustee or assignee under such mortgage, deed of trust or assignment and their successors and assigns.

11.                               The term “Tenant” refers to and means the Tenant named in the Lease and also Tenant’s successors and assigns.

12.                               In the event any action be brought by said Landlord against Guarantor hereunder to enforce the obligation of Guarantor hereunder, the unsuccessful party in such action shall pay to the prevailing party therein a reasonable attorney’s fee which shall be fixed by the court.

10

13.                               Provided Tenant has not had an uncured Default as described in the Lease, as of October 25, 2002, the liability of Guarantor hereunder shall be limited to the sum of $760,000.00. If no uncured Default has occurred under the Lease as of October 25, 2004, then this Guaranty shall terminate. It is agreed that if a Default occurs under the Lease which continues beyond the expiration of any applicable grace or cure period, Landlord may condition its acceptance of any cure of such Default upon keeping this Guaranty in effect.

14.                               This Guaranty shall supersede the Original Guaranty in its entirety, it being specifically agreed that Montgomery shall no longer have any liability as a guarantor of the Lease.

Executed to be effective as of the date and year first above written.

This instrument was acknowledged before me on August 30, 2002, by DARLENE M. RYAN.

Copy of Commission Agreement

COMMISSION AGREEMENT BETWEEN

WALSTIB, L.P., A DELAWARE LIMITED PARTNERSHIP

AND

FOBARE COMMERCIAL

THIS CONTRACT OF AGREEMENT, entered into by and between Walstib, L.P., a Delaware limited partnership hereinafter referred to as “Owner,” and Fobare Commercial hereinafter referred to as “Agent.”

W I T N E S S E T H :

Agent has assisted or is assisting Owner in negotiating and consummating a Lease Agreement between Owner and PharmaFab, Inc., hereinafter referred to as “Prospect,” covering an approximate 44,000 square foot facility located at (in) 360 Riverside Business Park (Building B) (the “Project”) for a term of 84 months beginning June 1, 1999 with rentals being due to Owner as therein provided, to which lease reference is hereby made, and the same is hereby incorporated herein for all purposes; and

Agent and Owner hereby and herein desire to agree upon a commission to which Agent shall be entitled for such services based on rentals actually received by Owner, as hereinafter provided.

It is mutually agreed as follows:

1. REGISTRATION

a.                                      Registration of the Prospect requires either (a) this Registration Letter from Agent naming the Prospect and a face-to-face meeting with a decision maker representing the Prospect or (b) a duly executed and authorized letter from the Prospect designating Agent as its exclusive Agent.

b.                                      This Registration and Agreement is effective for sixty (60) days after the date hereof and may be extended for another sixty (60) days if the Agent shows evidence satisfactory to Owner that Agent is actively pursuing the execution of a Lease Agreement between Owner and the Prospect.

c.                                       If at any time following the registration of the Prospect pursuant to (a) or (b) above, Agent loses control of the Prospect as evidenced by a letter from the Prospect designating some other Agent as the Prospect’s Agent, then upon notification of such event to Agent by Owner, this Registration Letter and Commission Agreement shall become null and void.

d.                                      Agent has satisfied the aforesaid initial registration requirements of Owner and accordingly Owner agrees to recognize PharmaFab, Inc. as Agent’s Prospect and agrees to pay a commission to Agent if a lease of space of the Project is consummated between the Prospect and Owner during the term of this Agreement.

2. CASH COMMISSION

a.                                      Primary Term. (1) If Agent requests a front-end cash-out of commission obligation hereunder, and if Prospect in Owner’s opinion has sufficient credit to meet all of Prospect’s obligations under the lease, Owner shall, as set forth in d. below, pay Agent as the Commission hereunder four and one-half percent (4-1/2%) of the total Rentals as hereafter payable for the entire initial term of the lease up to ten (10) years. Financial statements and other information necessary to determine credit risk are to be provided by Agent.

b.                                      Renewal. If Agent requests a front-end cash-out of the commission obligation hereunder with respect to a renewal option contained in the lease which has been duly exercised, and if Prospect in Owner’s opinion then has sufficient credit to meet all of Prospect’s obligations under the lease during the renewal term, Owner shall pay Agent the then prevailing market commission for a renewal, based upon the total Rentals payable for the renewal term, up to ten (10) years, providing that Agent is instrumental in assisting Owner in obtaining such renewal.

c.                                       Expansion. If Agent requests a front-end cash-out of the commission obligation hereunder with respect to an Option to Expand contained in the Lease Agreement which has been duly exercised prior to the termination of the Lease Agreement and if Prospect in Owner’s opinion then has sufficient credit to meet all of Prospect’s obligations under the lease as so expanded, Owner may pay Agent a commission of four and one-half percent (4-1/2%) of the total Rentals payable for the expansion space providing that Agent is instrumental in assisting Owner in obtaining such expansion.

d.                                      Time of Payment. (1) Initial Term. One-half (1/2) upon execution of the lease by Owner and Prospect, delivery thereof to both parties and receipt by Owner of first full month’s rent and any security deposit; and the balance upon occupancy by Prospect, delivery to Owner of satisfactory commencement letter executed by Prospect. In addition, no payment shall be payable until contingencies relating to the actual consummation or cancellation of the agreement by Prospect (including but not limited to contingencies regarding zoning, restrictive covenants, permitting, plan approvals and finish cost limits) are satisfactorily eliminated by the parties to the Lease Agreement. In addition for Build-to-Suit facilities no commission will be payable until Owner has received interim financing for the project.
