(a) Seller shall defend, hold harmless and indemnify each of the Purchaser Indemnitees from and against, and shall reimburse each of the Purchaser Indemnitees for, any Damages which are suffered or incurred by any of the Purchaser Indemnitees or to which any of the Purchaser Indemnitees may otherwise become subject at any time (regardless of whether of not such Damages relate to any third party claim) and which arise from or as a result of: (i) any gross negligence or willful misconduct of Seller or Seller Personnel; (ii) any Seller material breach, violation, or non-performance of any term, condition, or provision of this Agreement; (iii) Seller’s or Seller Personnel’s violation of applicable law that in each case relate to the use or occupancy of the Covered Facilities to the extent not attributable to Purchaser; or (iv) Seller’s or Seller Personnel’s storage, use, release or disposal of Hazardous Materials on or about the Covered Facilities.

Failure by the Indemnitee to comply with the obligations under this Section 8.3 shall relieve the Indemnitor of its obligations under Sections 8.1 and 8.2 only if and to the extent that the Indemnitor can show that its ability to defend the claim or settle the claim on favorable terms was materially prejudiced by the Indemnitee’s failure to comply with its obligations under this Section 8.3.

PURCHASER ACKNOWLEDGES THAT SELLER IS PROVIDING THE SERVICES AND OTHER ASSISTANCE DESCRIBED IN THIS AGREEMENT IN ORDER TO ASSIST THE FACILITATION OF PURCHASER’S INDEPENDENT OPERATIONS.

(b) Dispute Resolution. Except with respect to any claim seeking injunctive relief hereunder, in the event of any controversy or claim arising out of, relating to or in connection with any provision of this Agreement or the rights or obligations of the parties hereunder, the parties will try to settle their differences amicably between themselves as contemplated herein. To the extent not provided for herein, any party may initiate such informal dispute resolution by sending written notice of the dispute to the other party, and within [*] after such notice, the Chief Executive Officer of the Purchaser will meet with the Senior Vice President, Business Development of the Seller, for attempted resolution by good faith negotiations. If such persons are unable to resolve promptly such disputed matter, such dispute shall be finally settled by arbitration in accordance with the arbitration rules of the American Arbitration Association (“AAA”), then in force, by one (1) arbitrator appointed in accordance with said rules, provided that the appointed arbitrator shall have appropriate experience in the biopharmaceutical industry. The place of arbitration shall be San Francisco, California if initiated by the Seller, and Boston, Massachusetts, if initiated by the Purchaser.

Period		Monthly Rent
*[]**		[*]

(ii) “[*],” as that term is used in this subsection shall mean the [*] rate per month being charged to [*] for [*] leases of [*] and [*], determined as follows:

(1) At least [*] but not more than [*] days prior to [*], Sublandlord shall give Subtenant written notice of its estimate of [*]. Subtenant shall have [*] days after receipt of Sublandlord’s notice to accept such value or to object thereto in writing. In the event Subtenant objects, Sublandlord and Subtenant shall attempt to agree upon the [*], using their best good faith efforts. If Sublandlord and Subtenant fail to reach agreement within such [*] days, then each party’s determination shall be submitted to arbitration in accordance with the procedure set forth in the following subsections.

(2) Sublandlord and Subtenant shall each appoint one arbitrator who shall by profession be a real estate broker who shall have been active over the five (5) year period immediately preceding the date of such appointment in the leasing of [*].

(3) Not later than [*] days after both arbitrators are appointed, each party shall separately but simultaneously submit in a sealed envelope to each arbitrator their separate suggested [*] values. If the higher rate of the two submitted suggested [*] values does not exceed the lower rate by more than [*], then the two rates shall be averaged (thus splitting the difference and avoiding additional arbitration costs), with the resulting value becoming the [*].

(4) If the [*] is not established by the provisions in subsection (3) above, the two arbitrators appointed shall, on of before [*] days from the date of the appointment of the last appointed arbitrator, agree upon and appoint a third arbitrator who shall be qualified under the same criteria set forth above for qualification of the initial two arbitrators.

(5) Each of the three arbitrators, within [*] days of the appointment of the third arbitrator, shall independently determine the Fair Market Rental. If the higher and lower values determined by the arbitrators so not differ by more [*] from the middle value, all values shall be averaged and the resulting value shall be determined to be the [*]. If either of the arbitrator’s values differ from the middle value by more than [*], such value shall not be considered and the remaining values shall be averaged to determine the [*]. If two of the arbitrators’ values differ from the middle value by more than [*], neither such value shall be considered, and the middle value shall be deemed to be the [*].

(6) The cost of arbitration shall be paid by [*].

(b) Additional Rent. Subtenant shall pay to Sublandlord, as additional rent (“Additional Rent”), Subtenant’s Pro Rata Share of Operating Expenses accruing during the term of this Sublease.

66.

benefit of Sublandlord, such amounts shall not be pro rated between Sublandlord and Subtenant and shall be the sole responsibility of Sublandlord. For purposes hereof, Subtenant’s Pro Rata Share means [*].

Notwithstanding the foregoing, the following Sections of the Master Lease are not incorporated herein: Sections [*].

(b) In the event of any conflict between this Sublease and the Master Lease, as between Sublandlord and Subtenant, the terms and conditions of this Sublease shall control. Further, if Rent is abated under the Master Lease, Rent hereunder shall also be abated in the same proportion.

Subtenant expressly acknowledges that the foregoing representations under this clause (c) are made with respect to the period from and after February 12, 2002.

10. Brokerage. Each party warrants and represents to the other that such party has not retained any other real estate broker, finder or any other person whose services would form the basis for any claim for any commission or fee in connection with this Sublease or the transactions contemplated hereby. Each party agrees to save, defend, indemnify and hold the other party free and harmless from any breach of its warranty and representation as set forth in the preceding sentence, including the other party’s attorneys’ fees.

11. Sublandlord’s Obligations. Sublandlord shall have no obligation to Subtenant with respect to the Sublease Premises during the term hereof except as expressly otherwise provided herein nor shall Sublandlord have any obligation to Subtenant with respect to the performance by Master Landlord of any obligations of Master Landlord under the Master Lease, except to use best efforts to enforce Master Landlord’s obligations under the Master Lease. Such enforcement shall include, without limitation, upon Subtenant’s request, (a) immediately notifying Master Landlord of its non-performance under the Master Lease and requesting that

68.

Master Landlord perform its obligations under the Master Lease and/or (b) assigning Sublandlord’s rights under the Master Lease to Subtenant to the extent necessary to permit Subtenant to institute legal proceedings against Master Landlord to obtain the performance of Master Landlord’s obligations under the Master Lease; provided, however, that if Subtenant commences a lawsuit or other action, Subtenant shall pay all costs and expenses incurred in connection therewith, and Subtenant shall indemnify Sublandlord against, and hold Sublandlord harmless from, all costs and expenses incurred by Sublandlord in connection therewith.

12. Early Termination of Master Lease. If, without the fault of Sublandlord hereunder the Master Lease should terminate prior to the expiration of this Sublease, Sublandlord shall have no liability to Subtenant. To the extent that the Master Lease grants Sublandlord any discretionary right to terminate the Master Lease, whether due to casualty, condemnation, or otherwise, Sublandlord shall have the right to exercise such right with regard to the Sublease Premises in its sole and absolute discretion.

13. Modifications to Master Lease. Sublandlord shall not amend or modify the Master Lease in such a manner as to adversely affect Subtenant’s use of the Sublease Premises or increase the obligations or decrease the rights of Subtenant hereunder, without the prior written consent of Subtenant, which may be granted or withheld at Subtenant’s sole discretion.

14. Quiet Enjoyment. Subtenant shall peacefully have, hold and enjoy the Sublease Premises, subject to the terms and conditions of this Sublease and subject to the Master Lease, provided that Subtenant pays all rent and performs all of Subtenant’s covenants and agreements contained herein. If Master Landlord seeks to terminate the Master Lease because of a default or alleged default by Sublandlord under the Master Lease (other than a default or alleged default caused by the default by Subtenant under this Sublease), Sublandlord shall take all action required to reinstate the Master Lease. In the event that Sublandlord defaults in the performance or observance of any of Sublandlord’s obligations under this Sublease or receives a notice of default from Master Landlord under the Master Lease, then Subtenant shall give written notice to Sublandlord specifying in what manner Sublandlord has defaulted. If such default shall not be cured within a reasonable time, but in no event later than [*] days after Sublandlord’s receipt of such written notice from Subtenant (except that if such default cannot be cured within said [*] day period, this period shall be extended for an additional reasonable time, provided that Sublandlord commences to cure such default within such [*] day period and proceeds diligently thereafter to effect such cure as quickly as possible), then Subtenant shall be entitled, at Subtenant’s option, to cure such default and promptly collect from Sublandlord Subtenant’s reasonable expenses in so doing (including, without limitation, reasonable attorneys’ fees and court costs) unless such default by Sublandlord is caused by a default of Subtenant hereunder (in which case Sublandlord shall not be liable for Subtenant’s costs to cure the default). Subtenant shall not be required to wait the entire cure period provided for herein if earlier action is required to prevent a termination by Master Landlord of the Master Lease and Sublandlord has failed to take such earlier action. Nothing contained herein shall entitle Subtenant to act on behalf of Sublandlord or in Sublandlord’s name.

15. Consent of Master Landlord. If Subtenant desires to take any action which requires the consent of Master Landlord pursuant to the terms of the Master Lease, including, without limitation, the making of any alterations, then, notwithstanding anything to the contrary

69.

herein, (a) Sublandlord, independently, shall have the same rights of approval or disapproval as Master Landlord has under the Master Lease, (b) Subtenant shall not take any such action until it obtains the consent of both Sublandlord and Master Landlord, and (c) Subtenant shall request that Sublandlord obtain Master Landlord’s consent on Subtenant’s behalf and Sublandlord shall use commercially reasonable efforts to obtain such consent and any out-of-pocket expense of obtaining such consent shall be borne by Subtenant, unless Sublandlord and Master Landlord agree that Subtenant may contact Master Landlord directly with respect to the specific action for which Master Landlord’s consent is required.

16. No Third Party Rights. The benefit of the provisions of this Sublease is expressly limited to Sublandlord and Subtenant and their permitted successors and assigns. Under no circumstances will any third party be construed to have any rights as a third party beneficiary with respect to any of said provisions.

17. Master Landlord Consent to Sublease. This Sublease and Sublandlord’s and Subtenant’s obligations hereunder are conditioned upon having obtained the written consent of the Master Landlord to this Sublease.

18. Surrender. Subtenant’s obligation to surrender the Sublease Premises shall be fulfilled if Subtenant (i) surrenders possession of the Sublease Premises in the condition existing immediately prior to the Commencement Date, ordinary wear and tear, Hazardous Materials existing immediately prior to the Commencement Date, and interior improvements made by Subtenant which Sublandlord states in writing may be surrendered at the termination of the Sublease excepted; and (ii) completes all site closure activities relative to the Sublease Premises and receives all necessary governmental or regulatory approvals as may be required to decommission the Sublease Premises and obtain the site closure of all permits and licenses relating to Subtenant’s use of Hazardous Materials in the Sublease Premises.

19. Mutual Waiver of Subrogation. The waiver of subrogation provision set forth in Section 12.4 of the Master Lease shall be deemed a three party agreement binding among and inuring to the benefit of Sublandlord, Subtenant and Master Landlord (by reason of its consent to hereto).

20. Non-Disturbance. In the event that the Sublease terminates prior to the expiration of the term thereof for any reason other than as a result of an event of default by Subtenant under the Sublease, the Sublease shall continue in full force and effect, at Subtenant’s option, as a direct lease between the Master Landlord and Subtenant upon all of the terms, covenants and conditions of the Sublease and Master Landlord shall recognize Subtenant’s right to possession of the Premises as provided for in the Sublease and shall not disturb Subtenant’s right to possession so long as an event of default does not exist in the performance of Subtenant’s obligations under the Sublease.

21. Counterparts. This Sublease may be executed in any number of counterparts, each of which counterparts shall be deemed to be an original, and all of which together shall constitute one and the same instrument.

(b) Landlord shall not lease all or any portion of the First Refusal Space at any time during the term of this Lease (including any duly elected extension terms) except in compliance with the procedure set forth in Section 1.3(c) hereof; provided, however, that the foregoing restriction shall not apply during any period in which Tenant is in default (beyond any applicable cure periods) under this Lease; provided further, that the foregoing restriction shall not apply to any renewal or extension options duly elected by the applicable tenant or any successor tenant pursuant to a contractual renewal or extension option set forth in the lease documents governing the respective portions of the First Refusal Space on the date of this Lease, but such restriction shall apply to any future lease amendments or grants of renewal or extension rights with respect to any portion of the First Refusal Space that would have the effect of either extending the term of any existing occupancy of any portion of the First Refusal Space beyond the term presently specified in the lease documents governing such portion, or granting renewal or extension rights beyond those presently set forth in the applicable lease documents with respect to any portion of the First Refusal Space; and provided further, that the foregoing restriction shall not apply to any leasing, subleasing or other occupancy by Raven Pharmaceuticals, Inc. of all or any portion of the space described in clause (iii) of Section 1.3(a), whether pursuant to the sublease presently in effect between ViroLogic, Inc. and Raven Pharmaceuticals, Inc. or otherwise, provided that such leasing, subleasing or other occupancy by Raven Pharmaceuticals, Inc. shall not in any event be authorized to extend beyond June 30, 2003.

(c) If Landlord intends during the term of this Lease (including any duly elected extension terms) to lease all or any portion of the First Refusal Space, and if Tenant is not then in default (beyond any applicable cure periods) under this Lease, then Landlord shall give to Tenant written notice of such intention (the “Offer Notice”), specifying the material terms on which Landlord proposes to lease the First Refusal Space or applicable portion thereof (the “Offered Space”) and offering to Tenant the opportunity to lease the Offered Space on the terms specified in the Offer Notice. The time period within which Tenant is entitled to accept such offer by written notice to Landlord (the “Offer Period”), measured from the date of Tenant’s receipt of the Offer Notice, shall be ten (10) business days, except that if the Offered Space is all or substantially all of the 000 Xxxx Xxxxx Xxxxxxxx, then the Offer Period shall be thirty (301 days unless Tenant has previously received and failed to accept an Offer Notice with respect to such Offered Space in the 280 East Grand Building and Landlord is thereafter, within one hundred eighty (180) days after expiration of the Offer Period for such prior Offer Notice, coming back to Tenant with a further Offer Notice reflecting terms more favorable to the lessee than the terms offered in the prior Offer Notice, in which event the Offer Period for such further Offer Notice shall be ten (10) business days. Upon timely acceptance of an Offer Notice by Tenant, the Offered Space shall be leased to Tenant on the terms set forth in the Offer Notice and on the additional terms and provisions set forth herein (except to the extent inconsistent with the terms set forth in the Offer Notice) and the parties shall promptly execute an amendment to this Lease adding the Offered Space to the Premises and making any appropriate amendments to provisions of this Lease

to reflect different rent and other obligations applicable to the Offered Space under the terms of the Offer Notice. If Tenant does not accept Landlord’s offer within the allotted time, Landlord shall thereafter have the right to lease the Offered Space to a third party at any time within one hundred eighty (180) days after the expiration of the Offer Period, at a minimum rental and on other terms and conditions not more favorable to the lessee than the minimum rental and other terms offered to Tenant in the Offer Notice. If Landlord does not thereafter lease the Offered Space to a third party within one hundred eighty (180) days as contemplated in the preceding sentence, or if Landlord does lease the Offered Space to a third party within such 180-day period but the Offered Space thereafter again becomes available during the term of this Lease (including any duly elected extension terms), then in either such event Landlord shall be required to comply again with the provisions of this Section 1.3 prior to any further leasing of the Offered Space.

2.4 [Omitted.]

2.5 Holding Over. If Tenant holds possession of the Premises or any portion thereof after the term of this Lease with Landlord’s written consent, then except as otherwise specified in such consent, Tenant shall become a tenant from month to month at [*] the rental and otherwise upon the terms herein specified for the period immediately prior to such holding over and shall continue in such status until the tenancy is terminated by either party upon not less than thirty (30) days prior written notice. If Tenant holds possession of the Premises or any portion thereof after the term of this Lease without Landlord’s written consent, then Landlord in its sole discretion may elect (by written notice to Tenant) to have Tenant become a tenant either from month to month or at will, at [*] the rental (prorated on a daily basis for an at-will tenancy, if applicable) and otherwise upon the terms herein specified for the period immediately prior to such holding over, or may elect to pursue any and all legal remedies available to Landlord under applicable law with respect to such unconsented holding over by Tenant. Tenant shall indemnify and hold Landlord harmless from any loss, damage, claim, liability, cost or expense (including reasonable attorneys’ fees) resulting from any delay by Tenant in surrendering the Premises or any portion thereof (except to the extent such delay is with Landlord’s prior written consent), including but not limited to any claims made by a succeeding tenant by reason of such delay. Acceptance of rent by Landlord following expiration or termination of this Lease shall not constitute a renewal of this Lease.

2.6 Option To Extend Term. Tenant shall have the option to extend the term of this Lease, at the minimum rental set forth in Section 3.1(c) and (d) and otherwise upon all the terms and provisions set forth herein with respect to the initial term of this Lease, for up to [*] additional periods of [*] each, the first commencing upon the expiration of the initial term hereof and the second commencing upon the expiration of the first extended term, if any. Exercise of such

option with respect to the first such extended term shall be by written notice to Landlord at least nine (9) months and not more than twelve (12) months prior to the expiration of the initial term hereof; exercise of such option with respect to the second extended term, if the first extension option has been duly exercised, shall be by like written notice to Landlord at least nine (9) months and not more than twelve (12) months prior to the expiration of the first extended term hereof. If Tenant is in default hereunder, beyond any applicable notice and cure periods, on the date of such notice or on the date any extended team is to commence, then the exercise of the option shall be of no force or effect, the extended term shall not commence and this Lease shall expire at the end of the then current term hereof (or at such earlier time as Landlord may elect pursuant to the default provisions of this Lease). If Tenant properly exercises one or more extension options under this Section, then all references in this Lease (other than in this Section 2.6) to the “term” of this Lease shall be construed to include the extension terms) thus elected by Tenant. Except as expressly set forth in this Section 2.6, Tenant shall have no right to extend the term of this Lease beyond its prescribed term.

3. RENTAL

3.1 Minimum Rental.

(a) Rental Amounts. Tenant shall pay to Landlord as minimum rental for the Premises, in advance, without deduction, offset, notice or demand, on or before the Commencement Date and on or before the first day of each subsequent calendar month of the initial term of this Lease, the following amounts per month:


Months	Monthly Minimum Rental
[*]		[*]	[*]

If the obligation to pay minimum rental hereunder commences on other than the first day of a calendar month or if the term of this Lease terminates on other than the last day of a calendar month, the minimum rental for such first or last month of the term of this Lease, as the case may be, shall be prorated based on the number of days the term of this Lease is in effect during such month. If an increase in minimum rental becomes effective on a day other than the first day of a calendar month, the minimum rental for that month shall be the sum of the two applicable rates, each prorated for the portion of the month during which such rate is in effect.

(b) Rental Adjustment Due to Change in Square Footage. The minimum rental amounts specified in this Section 3.1 are based upon an agreed area of 136,242 square feet for the Premises as they exist on the Commencement Date. If the area of the Premises increases during the initial term of this Lease as a result of the construction of the new mezzanine area as contemplated in Section 2.3(b) and/or the construction of the new lobby area as contemplated in Section 2.3(c), then beginning on the date the applicable construction is substantially completed and the applicable new area becomes available for use or is actually used by Tenant in the ordinary course of its business, the minimum monthly rent for the remainder of the initial term of this Lease shall be increased, for each month, by an amount equal to the square footage of the newly constructed area (measured in accordance with Section 2.3(b)(iii) or 2.3(c)(iii), as applicable) multiplied by the applicable rental rate per square foot as set forth in Section 3.1(al above. In the event of any such increase in the area of the Premises during any extended term of this Lease, the minimum monthly rent during such extended term (as otherwise determined pursuant to Section 3.1(c) or 3.1(d), as applicable) shall be increased on a similar basis in strict proportion to the increase in the size of the Premises as a result of the newly constructed area being added to the Premises. Any rental increases due to a change in the square footage of the Premises as a result of Tenant’s exercise of a first refusal right under Section 1.3 hereof with respect to any of the First Refusal Space shall be determined and implemented in accordance with the provisions of Section 1.3 and the applicable Offer Notice thereunder.

(c) Rental Amounts During First Extended Term. If Tenant properly exercises its right to extend the term of this Lease pursuant to Section 2.6 hereof, the minimum rental during the first year of the first extended term shall be equal to the fair market rental value of the Premises (as defined below), including any cost-of-living adjustments or other rental increase provisions then customary in the City of South San Francisco for comparable commercial leases, determined as of the commencement of such extended term in accordance with this paragraph. Upon Landlord’s receipt of a proper notice of Tenant’s exercise of its option to extend the term of this Lease, the parties shall have sixty (60) days in which to agree on the initial fair market rental (including any applicable rental increase provisions) for the Premises at the commencement of the first extended term for the uses permitted hereunder. If the parties agree on

such initial fair market rental and rental increase provisions (if any), they shall execute an amendment to this Lease stating the amount of the applicable minimum monthly rental and any applicable rental increase provisions. If the parties are unable to agree on such rental (including any applicable rental increase provisions) within such sixty (60) day period, then within fifteen (15) days after the expiration of such period each party, at its cost and by giving notice to the other party, shall appoint a real estate appraiser with at least five (5) years experience appraising similar commercial properties in northeastern San Mateo County to appraise and set the initial fair market rental and any applicable rental increase provisions for the Premises at the commencement of the first extended term in accordance with the provisions of this Section 3.1(c). If either party fails to appoint an appraiser within the allotted time, the single appraiser appointed by the other party shall be the sole appraiser. If an appraiser is appointed by each party and the two appraisers so appointed are unable to agree upon an initial fair market rental (and any appropriate rental increase provisions) within thirty (30) days after the appointment of the second, the two appraisers shall appoint a third similarly qualified appraiser within ten (10) days after expiration of such 30-day period; if they are unable to agree upon a third appraiser, then either party may, upon not less than five (5) days notice to the other party, apply to the Presiding Judge of the San Mateo County Superior Court for the appointment of a third qualified appraiser. Each party shall bear its own legal fees in connection with appointment of the third appraiser and shall bear one-half of any other costs of appointment of the third appraiser and of such third appraiser’s fee. The third appraiser, however selected, shall be a person who has not previously acted for either party in any capacity. Within thirty (30) days after the appointment of the third appraiser, a majority of the three appraisers shall set the initial fair market rental and any applicable rental increase provisions for the first extended term and shall so notify the parties. If a majority are unable to agree within the allotted time, then (i) the three appraised initial fair market rentals shall be added together and divided by three and the resulting quotient shall be the initial fair market rental for the first extended term, and (ii) the applicable rental increase provision shall be equal to the mathematical average (or the nearest reasonable approximation thereto) of the two rental increase provisions that are most closely comparable, which determinations shall be binding on the parties and shall be enforceable in any further proceedings relating to this Lease. For purposes of this Section 3.1(c), the “fair market rental” of the Premises shall be determined with reference to the then prevailing market rental rates for properties in the City of South San Francisco with shell and office, laboratory and research and development improvements and site (common area) improvements comparable to those then existing in the Premises and in the Center, taking into account for such determination all tenant improvements then existing in the Premises (including, but not limited to, all fixtures, equipment and laboratory improvements in place in the Premises on the Commencement Date) other than alterations, improvements or equipment which were constructed or installed by Tenant at its sole expense and which Tenant has a right or obligation to remove from the Premises at the expiration of this Lease pursuant to the provisions of Article 9 hereof.

(d) Rental Amounts During Second Extended Term. If Tenant properly exercises its right to a second extended term of this Lease pursuant to Section 2.6 hereof, the minimum rental and any applicable rental increase provisions during such second extended term shall be determined in the same manner provided in the preceding paragraph for the first extended term, except that the determination shall be made as of the commencement of the second extended term.

3.2 Late Charge. If Tenant fails to pay rental or other amounts due Landlord hereunder on or before the fifth (5^th) day after such rental or other amount is due, such unpaid amounts shall bear interest for the benefit of Landlord at a rate equal to the lesser of [*] per annum or the maximum rate permitted by law, from the date due to the date of payment. In addition to such interest, Tenant shall pay to Landlord a late charge in an amount equal to [*] of any installment of minimum rental and any other amounts due Landlord if not paid in full on or before the fifth (5^th) day after such rental or other amount is due, Tenant acknowledges that late payment by Tenant to Landlord of rental or other amounts due hereunder will cause Landlord to incur costs not contemplated by this Lease, including, without limitation, processing and accounting charges and late charges which may be imposed on Landlord by the terms of any loan relating to the Center or any portion thereof. Tenant further acknowledges that it is extremely difficult and impractical to fix the exact amount of such costs and that the late charge set forth in this Section 3.2 represents a fair and reasonable estimate thereof. Acceptance of any late charge by Landlord shall not constitute a waiver of Tenant’s default with respect to overdue rental or other amounts, nor shall such acceptance prevent Landlord from exercising any other rights and remedies available to it. Acceptance of rent or other payments by Landlord shall not constitute a waiver of late charges or interest accrued with respect to such rent or other payments or any prior installments thereof, nor of any other defaults by Tenant, whether monetary or non-monetary in nature, remaining uncured at the time of such acceptance of rent or other payments.

4. [Omitted.]

5. [Omitted.]

6. TAXES

6.1 Personal Property. Tenant shall be responsible for and shall pay prior to delinquency all taxes and assessments levied against or by reason of (a) any and all alterations, additions and items installed or placed on or in the Premises and taxed as personal property rather than as real property, and/or (b) all personal property, trade fixtures and other property placed by Tenant on or about the Premises. Upon request by Landlord, Tenant shall furnish Landlord with satisfactory evidence of Tenant’s payment thereof. If at any time during the term of this Lease any of said alterations, additions or personal property, whether or not belonging to Tenant, shall be taxed or assessed as pan of the Center, then such tax or assessment shall be paid by Tenant to Landlord within fifteen (15) days after presentation by Landlord of copies of the tax bills in which such taxes and assessments are included and shall, for the purposes of this Lease, be deemed to be personal property taxes or assessments under this Section 6.1.

6.2 Real Property. To the extent any real property taxes and assessments on any portions of the Center (including, but not limited to, the Improvements or any portion thereof) leased or occupied solely by Tenant are assessed directly to Tenant, Tenant shall be responsible for and shall pay prior to delinquency all such taxes and assessments levied against the applicable portions of the Center. Upon request by Landlord, Tenant shall furnish Landlord with satisfactory evidence of Tenant’s payment thereof. To the extent the Center and/or Improvements are taxed or assessed to Landlord following the Commencement Date, such real property taxes and assessments shall constitute Operating Expenses (as that term is defined in Section 7.2 of this Lease) and shall be paid in accordance with the provisions of Article 7 of this Lease

7. OPERATING EXPENSES

7.1 Payment of Operating Expenses.

(a) Tenant shall pay to Landlord, at the time and in the manner hereinafter set forth, as additional rental, an amount equal to [*] (“Tenant’s Operating Cost Share”) of the Operating Expenses defined in Section 7.2, provided however, that the Tenant’s Operating Cost Share set forth in the preceding portion of this sentence shall apply only to expenses that are determined and allocated by Landlord on a Center-wide basis, subject to any adjustments required under any other applicable provisions of this Section 7.1, and that Tenant’s Operating Cost Share shall be [*] with respect to any Operating Expenses defined in Section 7.2 that are reasonably allocable solely to the Phase I Property. As of the date of this Lease, Landlord represents that the four buildings in which the Premises are located are the only buildings located on the Phase I Property and that Landlord’s current practice is to determine and allocate all Operating Expenses (including, but not limited to, real and personal property taxes and assessments, insurance, building maintenance, property management, landscape maintenance and irrigation, and parking area maintenance and lighting) on a stand-alone basis to the Phase I Property.

(b) Tenant’s Operating Cost Share as specified in paragraph (a) of this Section with respect to Operating Expenses which are determined and allocated on a Center-wide basis is based upon an area of 136,242 square feet for the Premises and upon an aggregate area of 562,859 square feet for the existing buildings owned by Landlord in the Center as depicted in the Site Plan. Tenant’s Operating Cost Share as specified in paragraph (a) of this Section with respect to Operating Expenses which are determined and allocated solely to the Phase I Property is based upon an area of 136,242 square feet for the Premises and upon an aggregate area of 177,938 square feet for the existing buildings on the Phase I Property, if the actual area of the buildings on the Phase I Property from time to time or of the buildings owned from time to time by Landlord in the Center and consolidated with the buildings in which the Premises are located for operation, maintenance, common area and Operating Expense purposes, as applicable, as such area is determined in good faith by Landlord’s architect on the same basis of measurement under which the Premises have been determined to contain 136.242 square feet (from the exterior faces of exterior walls and from the dripline of any overhangs, except that in the case of any two-story recesses or overhangs, the area to the dripline of the overhang is counted as part of the area of the first story but not as part of the area of the second story), differs from the assumed figures set forth above (including, but not limited to, any such difference arising from the construction of additional buildings in the Center as contemplated in Section 7.1(c) hereof), or if the area of the Premises changes from time to time pursuant to the construction of additional areas of the Premises pursuant to Section 2.3(b) and/or 2.3(c) and/or pursuant to Tenant’s exercise of a first refusal right pursuant to Section 1.3 hereof, then Tenant’s Operating Cost Share as it applies to Operating Expenses that are determined and allocated on a Center-wide basis or that are determined and allocated solely with respect to the Phase I Property, as applicable, shall be adjusted to reflect the actual areas so determined as they exist from time to time; provided, however, that in the event Tenant exercises a first refusal right with respect to the 000 Xxxx Xxxxx Xxxxxxxx. Xxxxxxxx hereby advises Tenant that it is presently Landlord’s practice to account for all Operating Expenses attributable or allocable to the

separate legal parcel on which the 000 Xxxx Xxxxx Xxxxxxxx is located on a stand-alone basis and to allocate such Operating Expenses one hundred percent (100%) to the tenant(s) of the 280 Fast Grand Building.

(c) If Landlord at any time constructs additional buildings in the Center or on any adjacent property owned by Landlord and operated, for common area purposes, on an integrated basis with the Center, then Tenant’s Operating Cost Share as it applies to Operating Expenses that are determined and allocated on a Center-wide basis shall be adjusted to be equal to the percentage determined by dividing the gross square footage of the Premises as they exist from time to time by the gross square footage of all buildings located in the Center or on any applicable adjacent property owned by Landlord as described above. In determining such percentage, a building shall be taken into account from and after the date on which a tenant first enters into possession of the building or a portion thereof, and the good faith determination of the gross square footage of any such building by Landlord’s architects shall be final and binding upon the parties.

7.2 Definition Of Operating Expenses.

7.3 Determination Of Operating Expenses. Tenant is already paying estimated Operating Expenses, pursuant to the Existing Lease, for calendar year 2001 based on estimates previously furnished by Landlord to Tenant. During the last month of each calendar year of the term of this Lease (“Lease Year”), or as soon thereafter as practical. Landlord shall provide Tenant notice of Landlord’s estimate of the Operating Expenses for the ensuing Lease Year or applicable portion thereof. On or before the first day of each month during each Lease Year or applicable portion thereof, beginning on the Commencement Date, Tenant shall pay to Landlord Tenant’s Operating Cost Share of the portion of such estimated Operating Expenses allocable (on a prorata basis) to such month; provided, however, that if such notice is not given in the last month of a Lease Year, Tenant shall continue to pay on the basis of the prior year’s estimate, if any, until the month after such notice is given. If at any time or times it appears to Landlord that the actual Operating Expenses will vary from Landlord’s estimate by more than five percent (5%). Landlord may, by notice to Tenant, revise its estimate for such year and subsequent payments by Tenant for such year shall be based upon such revised estimate.

7.4 Final Accounting For Lease Year.

(a) Within ninety (90) days after the close of each Lease Year, or as soon after such 90-day period as practicable, Landlord shall deliver to Tenant a statement of Tenant’s Operating Cost Share of the Operating Expenses for such Lease Year prepared by Landlord from Landlord’s books and records, which statement shall be final and binding on Landlord and Tenant (except as provided in Section 7.4(b)), if on the basis of such statement Tenant owes an amount that is more or less than the estimated payments for such Lease Year previously made by Tenant, Tenant or Landlord, as the case may be, shall pay the deficiency to the other party within thirty (30) days after delivery of the statement. Failure or inability of Landlord to deliver the annual statement within such ninety (90) day period shall not impair or constitute a waiver of Tenant’s obligation to pay Operating Expenses, or cause Landlord to incur any liability for damages.

(b) At any time within three (3) months after receipt of Landlord’s annual statement of Operating Expenses as contemplated in Section 7.4(a), Tenant shall be entitled, upon reasonable written notice to Landlord and during normal business hours at Landlord’s office or such other places as Landlord shall designate, to inspect and examine those books and records of Landlord relating to the determination of Operating Expenses for the immediately preceding Lease Year covered by such annual statement or, if Tenant so elects by written notice to Landlord, to request an independent audit of such books and records. The independent audit of the books and records shall be conducted by a certified public accountant acceptable to both Landlord and Tenant or, if the parties are unable to agree, by a certified public accountant appointed by the Presiding Judge of the San Mateo County Superior Court upon the application of either Landlord or Tenant I with notice to the other party). In either event, such certified public accountant shall be one who is not then employed in any capacity by Landlord or Tenant or by any of their respective affiliates. The audit shall be limited to the determination of the amount of Operating Expenses for the subject Lease Year, and shall be based on generally accepted accounting principles and tax accounting principles, consistently applied. If it is determined, by mutual agreement of Landlord and Tenant or by independent audit, that the amount of Operating Expenses billed to or paid by Tenant for the applicable Lease Year was incorrect, then the appropriate party shall pay to the other party the deficiency or overpayment, as applicable, within thirty (30) days after the final determination of such deficiency or overpayment. All costs and expenses of the audit shall be paid by Tenant unless the audit shows that Landlord overstated Operating Expenses for the subject Lease Year by more than five percent (5%), in which case Landlord shall pay all costs and expenses of the audit. Each party agrees to maintain the confidentiality of the findings of any audit in accordance with the provisions of this Section 7.4.

7.5 Proration. If the Commencement Date falls on a day other than the first day of a Lease Year or if this Lease terminates on a day other than the last day of a Lease Year, then the amount of Operating Expenses payable by Tenant with respect to such first or last partial Lease Year shall be prorated on the basis which the number of days during such Lease Year in which this Lease is in effect bears to 365. The termination of this Lease shall not affect the obligations of Landlord and Tenant pursuant to Section 7.4 to be performed after such termination.

Such insurance shall name Landlord, its general partners, its Managing Agent and any lender holding a deed of trust on the Center or any portion thereof from time to time (as designated in writing by Landlord to Tenant from time to time) as additional insureds thereunder. The amount of such insurance shall not be construed to limit any liability or obligation of Tenant under this Lease. Tenant shall also procure and maintain in full force and effect at all times during the term of this Lease, at Tenant’s cost and expense, products/completed operations coverage in an amount of not less than [*]

18.

and on other terms customary in Tenant’s industry for companies engaged in the marketing of products on a scale comparable to that in which Tenant is engaged from time to time.

(b) Landlord shall procure and maintain in full force and effect at all times during the term of this Lease, at Landlord’s cost and expense (but reimbursable as an Operating Expense under Section 7.2 hereof), commercial general liability insurance to protect against liability arising out of or related to the use of or resulting from any accident occurring in, upon or about the Center, with combined single limit of liability of not less than [*] per occurrence for bodily injury and property damage.

Landlord shall have no obligation to carry property damage -insurance for Tenant’s Property, for Tenant’s personal property or, except as expressly set forth in paragraph (d) below, for any alterations, additions or improvements installed by Tenant or by any predecessor tenant in the buildings in which the Premises are located or on or about the Center.

(d) Landlord shall procure and maintain in full force and effect at all times during the term of this Lease, at Tenant’s cost and expense (chargeable, in Landlord’s discretion, either as an Operating Expense allocable 100% to Tenant or as a direct pass-through to Tenant), policies of property insurance providing protection against “all risk of direct physical loss” (as defined by and detailed in the Insurance Service Office’s Commercial Property Program “Cause of Loss-Special Form [CP1030]” or its equivalent) for the tenant improvements existing in the Premises on the Commencement Date (other than Tenant’s Property, which it shall be Tenant’s responsibility to insure pursuant to paragraph (e) below), on a full replacement cost basis (with no co-insurance or, if coverage without co-insurance is not reasonably available, then on an “agreed amount” basis).

The coverage required to be maintained under this paragraph (d) may, in Landlord’s discretion, be added to or combined with Landlord’s master policy carried under paragraph (c) above (but, if not actually carried as part of Landlord’s master policy under paragraph (c) above, shall not carry a premium materially higher than would apply if such coverage were being carried as part of Landlord’s master policy under paragraph (c) above), in which event Tenant shall be named as an insured only with respect to the portion of the policy that covers tenant improvements as described in this paragraph (d). Tenant shall provide to Landlord from time to time, upon request by Landlord annually or at other reasonable intervals, an updated schedule of values for such existing tenant improvements, and Landlord shall have no obligation or liability with respect to any underinsurance of tenant improvements that results from Tenant’s failure to keep Landlord informed from time to time, on a current basis, of the insurable value of such tenant improvements.

Tenant shall deliver to Landlord copies of policies or certificates of insurance showing that said policies are in effect. The coverage provided by such

19.

policies shall include the clause or endorsement referred to in Section 12.4. If Tenant fails to acquire, maintain or renew any insurance required to be maintained by it under this Article 12 or to pay the premium therefor, then Landlord, at us option and in addition to its other remedies, but without obligation so to do, may procure such insurance, and any sums expended by it to procure any such insurance on behalf of or in place of Tenant shall be repaid upon demand, with interest as provided in Section 3.2 hereof. Tenant shall obtain written undertakings from each insurer under policies required to be maintained by it to notify all insureds thereunder at least thirty (30) days prior to cancellation of coverage.

This provision is intended to waive fully, and for the benefit of each party, any rights and claims which might give rise to a right of subrogation in any insurance carrier. Each party shall procure a clause or endorsement on any casualty insurance policy denying to the insurer rights of subrogation against the other party to the extent rights have been waived by the insured prior to the occurrence of injury or loss. Coverage provided by insurance maintained by Tenant shall not be limited, reduced or diminished by virtue of the subrogation waiver herein contained.

12.5 Increase in Premiums. Tenant shall do all acts and pay all expenses necessary to insure that the Premises are not used for purposes prohibited by any applicable fire insurance, and that Tenant’s use of the Premises and the Center complies with all requirements necessary to obtain any such insurance. If Tenant uses or permits the Premises to be used in a manner which increases the existing rate of any insurance carried by Landlord on the Center and such use continues for longer than a reasonable period specified in any written notice from Landlord to Tenant identifying the rate increase and the factors causing the same, then Tenant shall pay the amount of the increase in premium caused thereby, and Landlord’s costs of obtaining other replacement insurance policies, including any increase in premium, within ten (10) days after demand therefor by Landlord.

12.6 Indemnification.

(a) Tenant shall indemnify, defend and hold Landlord and its partners, shareholders, officers, directors, agents and employees harmless from any and all liability for injury to or death of any person, or loss of or damage to the property of any person, and all actions, claims, demands, costs (including, without limitation, reasonable attorneys’ fees), damages or expenses of any kind arising therefrom which may be brought or made against Landlord or which Landlord may pay or incur by reason of the use, occupancy and enjoyment of the Premises and the Center by Tenant or any invitees, sublessees, licensees, assignees, employees, agents or contractors of Tenant or holding under Tenant from any cause whatsoever other than negligence or willful misconduct or omission by Landlord, its agents or employees. Landlord and its partners, shareholders, officers, directors, agents and employees shall not be liable for, and Tenant hereby waives all claims against such persons for, damages to goods, wares and merchandise in or upon the Premises or the Center, or for injuries to Tenant, its agents or third persons in or upon the Premises or the Center, from any cause whatsoever other than negligence or willful misconduct or omission by Landlord, its agents or employees. Tenant shall give prompt notice to Landlord of any casualty or accident in, on or about the Premises or the Center.

(b) Landlord shall indemnify, defend and hold Tenant and its partners, shareholders, officers, directors, agents and employees harmless from any and all liability for injury to or death of any person, or loss of or damage to the property of any person, and all actions, claims, demands, costs (including, without limitation, reasonable attorneys’ fees), damages or expenses of any kind arising therefrom which may be brought or made against Tenant or which Tenant may pay or incur, to the extent such liabilities or other matters arise in, on or about the Premises or the Center by reason of any negligence or willful misconduct or omission by Landlord, its agents or employees.

20.

13. SUBLEASE AND ASSIGNMENT

13.1 Assignment of Lease and Sublease of Premises. Except in the case of a Permitted Transfer, Tenant shall not have the right or power to assign its interest in this Lease, or make any sublease of the Premises or any portion thereof, nor shall any interest of Tenant under this Lease be assignable involuntarily or by operation of law, without on each occasion obtaining the prior written consent of Landlord, which consent shall not be unreasonably withheld or delayed. Any purported sublease or assignment of Tenant’s interest in this Lease requiring but not having received Landlord’s consent thereto (to the extent such consent is required hereunder) shall be void. Without limiting the generality of the foregoing, Landlord may withhold consent to any proposed subletting or assignment for which consent is requested solely on the ground, if applicable, that the use by the proposed subtenant or assignee is reasonably likely to be incompatible with Landlord’s use of any adjacent property owned or operated by Landlord, unless the proposed use is within the permitted uses specified in Section 11.1, in which event it shall not be reasonable for Landlord to object to the proposed use. Except in the case of a Permitted Transfer, any dissolution, consolidation, merger or other reorganization of Tenant, or any sale or transfer of substantially all of the stock or assets of Tenant in a single transaction or series of related transactions, shall be deemed to be an assignment hereunder and shall be void without the prior written consent of Landlord as required above. Notwithstanding the foregoing, (i) any public offering of the common stock of Tenant shall not be deemed to be an assignment hereunder; (ii) any transfer of Tenant’s stock during any period in which Tenant has a class of stock listed on any recognized securities exchange or traded in the NASDAQ over-the-counter market shall not be deemed to be an assignment hereunder; (iii) any transfer of Tenant’s stock in connection with a bona fide financing, capitalization or recapitalization of Tenant shall not be deemed to be an assignment hereunder, provided that such financing, capitalization or recapitalization does not result in a material reduction in Tenant’s net worth or materially change the nature of Tenant’s ongoing business as a going concern; and (iv) Tenant shall have the right to assign this Lease or sublet the Premises or any portion thereof, without Landlord’s consent (but with prior or concurrent written notice by Tenant to Landlord, except to the extent Tenant is advised by its counsel that such prior or concurrent notice would be in violation of applicable law, in which event Tenant shall give such written notice as soon as reasonably possible after the giving of such notice is no longer in violation of applicable law), to any Affiliate of Tenant, or to any entity which results from a merger or consolidation with Tenant, or to any entity which acquires substantially all of the stock or assets of Tenant as a going concern (hereinafter each a “Permitted Transfer”). For purposes of the preceding sentence, an “Affiliate” of Tenant shall mean any entity in which Tenant owns at least a fifty percent (50%) equity interest, any entity which owns at least a fifty percent (50%) equity interest in Tenant, and/or any entity which is related to Tenant by a chain of ownership interests involving at least a fifty percent (50%) equity interest at each level in the chain. Landlord shall have no right to terminate this Lease in connection with, and shall have no right to any sums or other economic consideration resulting from, any Permitted Transfer. Except as expressly set forth in this Section 13.1, however, the provisions of Section 13.2 shall remain applicable to any Permitted Transfer and the transferee under such Permitted Transfer shall be and remain subject to all of the terms and provisions of this Lease.

13.2 Rights Of Landlord.

(a) Consent by Landlord to one or more assignments of this Lease, or to one or more sublettings of the Premises or any portion thereof, or collection of rent by Landlord from any assignee or sublessee, shall not operate to exhaust Landlord’s rights under this Article 13, nor constitute consent to any subsequent assignment or subletting. No assignment of Tenant’s interest in this Lease and no sublease shall relieve Tenant of its obligations hereunder, notwithstanding any waiver or extension of time granted by Landlord to any assignee or sublessee, or the failure of Landlord to assert its rights against any assignee or sublessee, and regardless of whether Landlord’s consent thereto is given or required to be given hereunder. In the event of a default by any assignee, sublessee or other successor of Tenant in the performance of any of the terms or obligations of Tenant under this Lease. Landlord may proceed directly against Tenant without the necessity of exhausting remedies against any such assignee, sublessee or other successor. In addition, Tenant immediately and irrevocably assigns to Landlord, as security for Tenant’s obligations under this Lease, all rent from any subletting of all or a part of the Premises as permitted under this Lease, and Landlord, as Tenant’s assignee and as attorney-in-fact for Tenant, or any receiver for Tenant appointed on Landlord’s application, may collect such rent and apply it toward Tenant’s obligations under this Lease; except that, until the occurrence of an act of default by Tenant, Tenant shall have the right to collect such rent and to retain all sublease profits (subject to the provisions of Section 13.2(c), below).

(b) Upon any assignment of Tenant’s interest in, this Lease for which Landlord’s consent is required under Section 13.1 hereof, Tenant shall pay to Landlord, within ten (10) days after receipt thereof by Tenant from time to time, one-half (1/2) of all cash sums and other economic considerations received by Tenant in connection with or as a result of such assignment, after first deducting therefrom (i) any costs incurred by Tenant for leasehold improvements

14.1 Right Of Entry. Landlord and its authorized representatives shall have the right to enter the Premises at any time during the term of this Lease during normal business hours and upon not less than twenty-four (24) hours prior notice, except in the case of emergency (in which event no notice shall be required and entry may be made at any time), for the purpose of inspecting and determining the condition of the Premises or for any other proper purpose including, without limitation, to make repairs, replacements or improvements which Landlord may deem necessary, to show the Premises to prospective purchasers, to show the Premises to prospective tenants (but only during the final year of the term of this Lease), and to post notices of nonresponsibility.

14.2 Quiet Enjoyment. Landlord covenants that Tenant, upon paying the rent and performing its obligations hereunder and subject to all the terms and conditions of this Lease, shall peacefully and quietly have, hold and enjoy the Premises and the Common Areas of the Center throughout the term of this Lease, or until this Lease is terminated as provided by this Lease.

15. CASUALTY AND TAKING

15.1 Damage or Destruction.

(a) If the Premises, or the Common Areas of the Center necessary for Tenant’s use and occupancy of the Premises, are damaged or destroyed in whole or in part under circumstances in which (i) repair and restoration is permitted under applicable governmental laws, regulations and building codes then in effect and (ii) repair and restoration reasonably can be completed within a period of one (1) year (or, in the case of an occurrence during the last year of the term of this Lease, within a period of sixty (60) days) following the date of the occurrence, then Landlord, as to the Common Areas of the Center and the cold shell of the buildings in which the Premises are located, and Tenant, as to all other improvements existing in or about the Premises immediately prior to such occurrence, shall commence and complete, with all due diligence and as promptly as is reasonably practicable under the conditions then existing, all such repair and restoration as may be required to return the affected portions of the Premises and the Center to a condition comparable to that existing immediately prior to the occurrence. In the event of damage or destruction the repair of which is not permitted under applicable governmental laws, regulations and building codes then in effect, if such damage or destruction (despite being corrected to the extent then permitted under applicable governmental laws, regulations and building codes) would still materially impair Tenant’s ability to conduct its business in the Premises, then either party may terminate this Lease as of the date of the occurrence by giving written notice to the other within thirty (30) days after the date of the occurrence; if neither party timely elects such termination, or if such damage or destruction does not materially impair Tenant’s ability to conduct its business in the Premises, then this Lease shall continue in full force and effect,

22.

except that there shall be an equitable adjustment in monthly minimum rental and of Tenant’s Operating Cost Share of Operating Expenses, based upon the extent to which Tenant’s ability to conduct its business in the Premises is impaired, and Landlord and Tenant respectively shall restore the Common Areas and the cold shell of the applicable buildings and the other improvements in and about such buildings to a complete architectural whole and to a functional condition. In the event of damage or destruction which cannot reasonably be repaired within one (1) year (or, in the case of an occurrence during the last year of the term of this Lease, within a period of sixty (60) days) following the date of the occurrence, then either Landlord or Tenant, at its election, may terminate this Lease as of the date of the occurrence by giving written notice to the other within thirty (30) days after the date of the occurrence; if neither party timely elects such termination, then this Lease shall continue in full force and effect and Landlord and Tenant shall each repair and restore applicable portions of the Premises and the Center in accordance with the first sentence of this Section 15.1.

(b) The respective obligations of Landlord and Tenant pursuant to Section 15.1(a) are subject to the following limitations:

(i) If the occurrence results from a peril which is required to be insured pursuant to Sections 12.1(c), (d) and (e) above, then Landlord and Tenant shall use their respective best efforts and cooperate diligently, reasonably and in good faith to recover any available proceeds from the respective insurance which they are required to maintain pursuant to Sections 12.1(c), (d) and/or (e), as applicable, and to divide or allocate such proceeds between themselves in accordance with their respective rebuilding obligations under Section 15.1(a), and the obligations of each party shall not exceed its respective share of the amount of insurance proceeds received from insurers (or, in the case of any failure to maintain required insurance, proceeds that reasonably would have been available if the required insurance had been maintained) by reason of such occurrence, plus the amount of any deductible under the applicable insurance, and, if such proceeds (including, in the case of a failure to maintain required insurance, any proceeds that reasonably would have been available) are insufficient, either party may terminate the Lease unless the other party promptly elects and agrees, in writing, to contribute the amount of the shortfall; and

(ii) if the occurrence results from a peril which is not required to be insured pursuant to Sections 12.1(c), (d) and (e) above and is not actually insured, Landlord shall be required to repair and restore the cold shells of the applicable buildings and the Common Areas to the extent necessary for Tenant’s continued use and occupancy of the Premises, and Tenant shall be required to repair and restore the other improvements in and about the Premises to the extent necessary for Tenant’s continued use and occupancy of the Premises marked that each party’s obligation to repair and restore shall not exceed an amount equal to five percent (5%) of the replacement cost of the cold shells of the applicable buildings and the Common Area improvements, as to Landlord, or five percent (5%) of the replacement cost of the other improvements in and about the Premises, as to Tenant; if the replacement cost as to either party exceeds such amount, then the party whose limit has been exceeded may terminate this Lease unless the other party promptly elects and agrees, in writing, to contribute the amount of the shortfall.

(c) If this Lease is terminated pursuant to the foregoing provisions of this Section 15.1 following an occurrence which is a peril actually insured or required to be insured against pursuant to Sections 12.1(c), (d) and (e), Landlord and Tenant agree (and any Lender shall he asked to agree) that such insurance proceeds shall be allocated between Landlord and Tenant in a manner which fairly and reasonably reflects their respective ownership rights under this Lease, as of the termination or expiration of the term of this Lease, with respect to the improvements, fixtures, equipment and other items to which such insurance proceeds are attributable.

(d) From and after the date of an occurrence resulting in damage to or destruction of the Premises or of the Common Areas necessary for Tenant’s use and occupancy of the Premises, and continuing until repair and restoration thereof are completed, there shall be an equitable abatement of minimum rental and of Tenant’s Operating Cost Share of Operating Expenses based upon the degree to which Tenant’s ability to conduct its business in the Premises is impaired.

15.2 Condemnation.

(a) If during the term of this Lease the Premises or the Common Areas of the Center, or any substantial part of either, is taken by eminent domain or by reason of any public improvement or condemnation proceeding, or in any manner by exercise of the right of eminent domain (including any transfer in avoidance of an exercise of the power of eminent domain), or receives irreparable damage by reason of anything lawfully done under color of public or other authority, then (i) this Lease shall terminate as to the entire Premises at Landlord’s election by written

23.

notice given to Tenant within sixty (60) days after the taking has occurred, and (ii) this Lease shall terminate as to the entire Premises at Tenant’s election, by written notice given to Landlord within thirty (30) days after the nature and extent of the taking have been finally determined, if the portion of the Premises taken is of such extent and nature as substantially to handicap, impede or permanently impair Tenant’s use of the balance of the Premises. If Tenant elects to terminate this Lease, Tenant shall also notify Landlord of the date of termination, which xxxx shall not be earlier than thirty (30) days nor later than ninety (90) days after Tenant has notified Landlord of Tenant’s election to terminate, except that this Lease shall terminate on the date of taking if such date falls on any date before the date of termination designated by Tenant. If neither party elects to terminate this Lease as hereinabove provided, this Lease shall continue in full force and effect (except that there shall be an equitable abatement of minimum rental and of Tenant’s Operating Cost Share of Operating Expenses based upon the degree to which Tenant’s ability to conduct its business in the Premises is impaired). Landlord shall restore the shell of the buildings in which the Premises are located and Common Area improvements to a complete architectural whole and a functional condition and as nearly as reasonably possible to the condition existing before the taking, and Tenant shall restore the other improvements in the Premises and Tenant’s other alterations, additions and improvements to a complete architectural whole and a functional condition and as nearly as reasonably possible to the condition existing before the taking. In connection with any such restoration, each party shall use its respective best efforts (including, without limitation, any necessary negotiation or intercession with its respective lender, if any) to ensure that any severance damages or other condemnation awards intended to provide compensation for rebuilding or restoration costs are promptly collected and made available to Landlord and Tenant in portions reasonably corresponding to the cost and scope of their respective restoration obligations, subject only to such payment controls as either party or its lender may reasonably require in order to ensure the proper application of such proceeds toward the restoration of the Improvements. Each party waives the provisions of Code of Civil Procedure Section 1265.130, allowing either party to petition the Superior Court to terminate this Lease in the event of a partial condemnation of the Premises or the Center.

(b) The respective obligations of Landlord and Tenant pursuant to Section 15.2(a) are subject to the following limitations:

(i) Each party’s obligation to repair and restore shall not exceed, net of any condemnation awards or other proceeds available for and allocable to such restoration as contemplated in Section 15.2(a), an amount equal to five percent (5%) of the replacement cost of the shell of the buildings in which the Premises are located and the Common Area improvements, as to Landlord, or five percent (5%) of the replacement cost of the other improvements in the Premises as to Tenant: if the replacement cost as to either party exceeds such amount, then the party whose limit has been exceeded may terminate this Lease unless the other party promptly elects and agrees, in writing, to contribute the amount of the shortfall; and

(ii) If this Lease is terminated pursuant to the foregoing provisions of this Section 15.2, or if this Lease remains in effect but any condemnation awards or other proceeds become available as compensation for the loss or destruction of any of the improvements, then Landlord and Tenant agree (and any Lender shall be asked to agree) that such proceeds shall be allocated between Landlord and Tenant, respectively, in the respective proportions in which Landlord and Tenant would have shared, under Section 15.1(c), the proceeds of any insurance proceeds following loss or destruction of the applicable improvements by an insured casualty.

15.3 Reservation Of Compensation. Landlord reserves, and Tenant waives and assigns to Landlord, all rights to any award or compensation for damage to the Premises, the Improvements, the Center and the leasehold estate created hereby, accruing by reason of any taking in any public improvement, condemnation or eminent domain proceeding or in any other manner by exercise of the right of eminent domain or of anything lawfully done by public authority, except that (a) Tenant shall be entitled to any and all compensation or damages paid for or on account of Tenant’s moving expenses, trade fixtures and equipment and any leasehold improvements installed by Tenant in the Premises at its own sole expense, but only to the extent Tenant would have been entitled to remove such items at the expiration of the term of this Lease and then only to the extent such compensation or damages are expressly and specifically allocated by the condemning authority, in response to a direct claim by Tenant, to Tenant’s moving expenses, trade fixtures, equipment and/or removable leasehold improvements as set forth in this clause (a), and (b) any condemnation awards or proceeds described in Section 15.2(b)(ii) shall be allocated and disbursed in accordance with the provisions of Section 15.2th)(ii), notwithstanding any contrary provisions of this Section 15.3.

15.4 Restoration Of Improvements. In connection with any repair or restoration of the Premises or other improvements by either party following a casualty or taking as hereinabove set forth, the party responsible for such repair or restoration shall, to the extent possible, return such Improvements to a condition substantially equal to that which

24.

existed immediately prior to the casualty or taking. To the extent such party wishes to make material modifications to the Premises or to such Improvements, such modifications shall be subject to the prior written approval of the other party (not to be unreasonably withheld or delayed), except that no such - approval shall be required for modifications that are required by applicable governmental authorities as a condition of the repair or restoration, unless such required modifications would impair or impede Tenant’s conduct of its business in the Premises (in which case any such modifications in Landlord’s work shall require Tenant’s consent, not unreasonably withheld or delayed) or would materially and adversely affect the exterior appearance, the structural integrity or the mechanical or other operating systems of the buildings in which the Premises are located (in which case any such modifications in Tenant’s work shall require Landlord’s consent, not unreasonably withheld or delayed).

16. DEFAULT

16.1 Events Of Default. The occurrence of any of the following shall constitute an event of default on the part of Tenant:

(a) [Omitted]

(b) Nonpayment. Failure to pay, when due, any amount payable to Landlord hereunder, such failure continuing for a period of five (5) business days after written notice of such failure; provided, however, that any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 et seq., as amended from time to time;

(c) Other Obligations. Failure to perform any obligation, agreement or covenant under this Lease other than those matters specified in subsection (b) hereof, such failure continuing for thirty (30) days after written notice of such failure; provided, however, that if such failure is curable in nature but cannot reasonably be cured within such 30-day period, then Tenant shall not be in default if, and so long as, Tenant promptly (and in all events within such 30-day period) commences such cure and thereafter diligently pursues such cure to completion; and provided further, however, that any such notice shall be in lieu of, and not in addition to, any notice required under California Code of Civil Procedure Section 1161 et seq., as amended from time to time;

(d) General Assignment. A general assignment by Tenant for the benefit of creditors;

(e) Bankruptcy.

Specifically, but without limiting the generality of the foregoing, such adequate assurances must include assurances that the Premises continue to be operated only for the use permitted hereunder. The provisions hereof are to assure that the basic understandings between Landlord and Tenant with respect to Tenant’s use of the Premises and the Common Areas and the benefits to Landlord therefrom are preserved, consistent with the purpose and intent of applicable bankruptcy laws:

(f) Receivership. The employment of a receiver appointed by court order to take possession of substantially all of Tenant’s assets or the Premises, if such receivership remains undissolved for a period of thirty (30) days;

25.

arrangement, composition, readjustment, liquidation, dissolution or similar relief under any present or future statute, law or regulation, such proceeding shall not have been dismissed.

16.2 Remedies Upon Tenant’s Default.

(a) Upon the occurrence of any event of default described in Section 16.1 hereof, Landlord, in addition to and without prejudice to any other rights or remedies it may have, shall have the immediate right to re-enter the Premises or any part thereof and repossess the same, expelling and removing therefrom all persons and property (which property may be stored in a public warehouse or elsewhere at the cost and risk of and for the account of Tenant), using such force as may be necessary to do so (as to which Tenant hereby waives any claim for loss or damage that may thereby occur). In addition to or in lieu of such re-entry, and without prejudice to any other rights or remedies it may have, Landlord shall have the right either (i) to terminate this Lease and recover from Tenant all damages incurred by Landlord as a result of Tenant’s default, as hereinafter provided, or (ii) to continue this Lease in effect and recover rent and other charges and amounts as they become due.

(b) Even if Tenant has breached this Lease and abandoned the Premises, this Lease shall continue in effect for so long as Landlord does not terminate Tenant’s right to possession under subsection (a) hereof and Landlord may enforce all of its rights and remedies under this Lease, including the right to recover rent as it becomes due, and Landlord, without terminating this Lease, may exercise all of the rights and remedies of a lessor under California Civil Code Section 1951.4 (lessor may continue lease in effect after lessee’s breach and abandonment and recover rent as it becomes due, if lessee has right to sublet or assign, subject only to reasonable limitations), or any successor Code section.

The “worth at the time of award” of the amounts referred to in clauses (i) and (ii) above shall be computed by allowing interest at ten percent (10%) per annum from the date such amounts accrued to Landlord. The “worth at the time of award” of the amounts referred to in clause (iii) above shall be computed by discounting such amount at one percentage point above the discount rate of the Federal Reserve Bank of San Francisco at the time of award.

16.3 Remedies Cumulative. All rights, privileges and elections or remedies of Landlord contained in this Article 16 are cumulative and not alternative to the extent permitted by law and except as otherwise provided herein.

17. SUBORDINATION, ATTORNMENT AND SALE

17.1 Subordination To Mortgage. This Lease, and any sublease entered into by Tenant under the provisions of this Lease, shall be subject and subordinate to any ground lease, mortgage, deed of trust, sale/leaseback transaction or any other hypothecation for security now or hereafter placed upon any portion(s) of the Center on which the Premise are located, and to the rights of any assignee of Landlord or of any ground lessor, mortgagee, trustee, beneficiary or leaseback lessor under any of the foregoing, and to any and all advances made on the security thereof and to all renewals, modifications, consolidations, replacements and extensions thereof; provided, however, that such subordination in the case of any future ground lease, mortgage, deed of trust, sale/leaseback transaction or any other hypothecation for security placed upon any portion(s) of the Center on which the Premises are located shall be conditioned on Tenant’s receipt from the ground lessor, mortgagee, trustee, beneficiary or leaseback lessor of a Non-Disturbance Agreement in a form reasonably acceptable to Tenant (i) confirming that so long as Tenant is not in material default hereunder beyond any applicable cure period (for which purpose the occurrence of any event of default under Section 16.1 hereof shall be

26.

deemed to be “material”), Tenant’s rights hereunder shall not be disturbed by such person or entity and (ii) agreeing that the benefit of such Non-Disturbance Agreement shall be transferable to any transferee under a Permitted Transfer and to any other assignee or subtenant that is acceptable to the ground lessor, mortgagee, trustee, beneficiary or leaseback lessor at the time of transfer. Moreover, Tenant’s obligations under this Lease shall be conditioned on Tenant’s receipt, within sixty (60) days after the date hereof (provided that Landlord shall have the right to extend such period for up to an additional thirty (30) days in order to continue pursuing receipt of the agreement required hereunder if not received within such initial 60-day period), from The Northwestern Mutual Life Insurance Company, the beneficiary under an existing deed of trust on the Phase I Property, of a Non-Disturbance Agreement in a form reasonably acceptable to Tenant acknowledging and approving this Lease and confirming (i) that so long as Tenant is not in material default hereunder beyond any applicable cure period (for which purpose the occurrence of any event of default under Section 16.1 hereof shall be deemed to be “material”), Tenant’s rights hereunder shall not be disturbed by such person or entity and (ii) agreeing that the benefit of such Non-Disturbance Agreement shall be transferable to any transferee under a Permitted Transfer and to any other assignee or subtenant that is acceptable to the ground lessor, mortgagee, trustee, beneficiary or leaseback lessor at the time of transfer. If any mortgagee, trustee, beneficiary, ground lessor, sale/leaseback lessor or assignee elects to have this Lease be an encumbrance prior to the lien of its mortgage, deed of trust, ground lease or leaseback lease or other security arrangement upon any portion(s) of the Center on which the Premises are located and gives notice thereof to Tenant, this Lease shall be deemed prior thereto, whether this Lease is dated prior or subsequent to the date thereof or the date of recording thereof. Tenant, and any sublessee, shall execute such documents as may reasonably be requested by any mortgagee, trustee, beneficiary, ground lessor, sale/leaseback lessor or assignee to evidence the subordination herein set forth, subject to the conditions set forth above, or to make this Lease prior to the lien of any mortgage, deed of trust, ground lease, leaseback lease or other security arrangement, as the case may be. Upon any default by Landlord in the performance of its obligations under any mortgage, deed of trust, ground lease, leaseback lease or assignment, Tenant (and any sublessee) shall, notwithstanding any subordination hereunder, attorn to the mortgagee, trustee, beneficiary, ground lessor, leaseback lessor or assignee thereunder upon demand and become the tenant of the successor in interest to Landlord, at the option of such successor in interest, and shall execute and deliver any instrument or instruments confirming the attornment herein provided for.

17.2 Sale of Landlord’s Interest. Upon sale, transfer or assignment of Landlord’s entire interest in the portion(s) of the Center on which the Premises are located. Landlord shall be relieved of its obligations hereunder with respect to liabilities accruing from and after the date of such sale, transfer or assignment.

17.3 Estoppel Certificates. Tenant or Landlord (the “responding party”), as applicable, shall at any time and from time to time, within ten (10) days after written request by the other party (the “requesting party”), execute, acknowledge and deliver to the requesting party a certificate in writing stating: (i) that this Lease is unmodified and in full force and effect, or if there have been any modifications, that this Lease is in full force and effect as modified and stating the date and the nature of each modification; (ii) the date to which rental and all other sums payable hereunder have been paid; (iii) that the requesting party is not in default in the performance of any of its obligations under this Lease, that the certifying party has given no notice of default to the requesting party and that no event has occurred which, but for the expiration of the applicable time period, would constitute an event of default hereunder, or if the responding party alleges that any such default, notice or event has occurred, specifying the same in reasonable detail; and (iv) such other matters as may reasonably be requested by the requesting party or by any institutional lender, mortgagee, trustee, beneficiary, ground lessor, sale/leaseback lessor or prospective purchaser of any portion(s) of the Center on which the Premises are located, or any prospective sublessee or assignee of this Lease. Any such certificate provided wider this Section 17.3 may be relied upon by any lender, mortgagee, trustee, beneficiary, assignee or successor in interest to the requesting party, by any prospective purchaser, by any purchaser on foreclosure or sale, by any grantee under a deed in lieu of foreclosure of any mortgage or deed of trust on the Center (or any portion thereof), by any subtenant or assignee, or by any other third party. Failure to execute and return within the required time any estoppel certificate requested hereunder, if such failure continues for five (5) days after a second written request by the requesting party for such estoppel certificate, shall be deemed to be an admission of the truth of the matters set forth in the form of certificate submitted to the responding party for execution.

17.4 Subordination to CC&R’s. This Lease, and any permitted sublease entered into by Tenant under the provisions of this Lease, and the interests in real property conveyed hereby and thereby shall be subject and subordinate to any declarations of covenants, conditions and restrictions affecting the Center (or any portion thereof) from time to time, provided that the terms of such declarations are reasonable, do not materially impair Tenant’s ability to conduct the uses permitted hereunder on the Premises and in the Center, and do not discriminate against Tenant relative to other similarly situated tenants occupying the portion(s) of the Center covered by such declaration(s). Moreover, this Lease, and any permitted sublease entered into by Tenant under the provisions of this Lease, and the interests in real property conveyed

27.

hereby and thereby shall also be subject and subordinate (a) to the Declaration of Covenants, Conditions and Restrictions for Pointe Grand Business Park dated November 4, 1991 and recorded on February 25, 1992 as Instrument No. 92025214, Official Records of San Mateo County, as amended from time to time (the “Master Declaration”), the provisions of which Master Declaration are an integral part of this Lease to the extent this sentence is applicable, (b) to the Declaration of Covenants, Conditions and Restrictions dated November 23, 1987 and recorded on November 24, 1987 as Instrument No. 87177987, Official Records of San Mateo County, which declaration imposes certain covenants, conditions and restrictions on the Pointe Grand Business Park, and (c) to the Environmental Restriction and Covenant (Pointe Grand) dated as of April 16, 1997 and recorded on April 16, 1997 as Instrument No. 97-043682, Official Records of San Mateo County, which declaration imposes certain covenants, conditions and restrictions on the Pointe Grand Business Park. Tenant agrees to execute, upon request by Landlord, any documents reasonably required from time to time to evidence such subordination.

17.5 Mortgagee Protection. If, following a default by Landlord under any mortgage, deed of trust, ground lease, leaseback lease or other security arrangement covering any portion(s) of the Center on which the Premises are located, any such portion(s) of the Center are acquired by the mortgagee, beneficiary, master lessor or other secured party, or by any other successor owner, pursuant to a foreclosure, trustee’s sale, sheriffs sale, lease termination or other similar procedure (or deed in lieu thereof), then any such person or entity so acquiring any portion(s) of the Center on which the Premises are located shall not be:

(a) liable for any act or omission of a prior landlord or owner of such portion(s) of the Center (including, but not limited to, Landlord);

(b) subject to any offsets or defenses that Tenant may have against any prior landlord or owner of such portion(s) of the Center (including, but not limited to, Landlord):

(c) bound by any rent or additional rent that Tenant may have paid in advance to any prior landlord or owner of such portion(s) of the Center (including, but not limited to, Landlord) for a period in excess of one month, or by any security deposit, cleaning deposit or other prepaid charge that Tenant may have paid in advance to any prior landlord or owner (including, but not limited to, Landlord), except to the extent such deposit or prepaid amount has been expressly turned over to or credited to the successor owner thus acquiring such portion(s) of the Center:

(d) liable for any warranties or representations of any nature whatsoever, whether pursuant to this Lease or otherwise, by any prior landlord or owner of such portion(s) of the Center (including, but not limited to, Landlord) with respect to the use, construction, zoning, compliance with laws, title, habitability, fitness for purpose or possession, or physical condition (including, without limitation, environmental matters) of the Center or any portion thereof; or

REPRESENTATIONS AND WARRANTIES OF PURCHASERS.

Each Purchaser hereby represents and warrants to the Company, severally and not jointly, as follows (provided that such representations and warranties do not lessen or obviate the representations and warranties of the Company set forth in this Agreement):

4.1 Requisite Power and Authority. Purchaser has all necessary power and authority to execute and deliver this Agreement and the Related Agreements and to carry out their provisions. All action on Purchaser’s part required for the lawful execution and delivery of this Agreement and the Related Agreements has been taken. Upon their execution and delivery, this Agreement and the Related Agreements will be valid and binding obligations of Purchaser, enforceable in accordance with their terms, except (a) as limited by applicable bankruptcy, insolvency, reorganization, moratorium or other laws of general application affecting enforcement of creditors’ rights, (b) as limited by general principles of equity that restrict the availability of equitable remedies and (c) to the extent that the enforceability of the indemnification provisions of the Investor Rights Agreement may be limited by applicable laws.

4.2 Investment Representations. Purchaser understands that neither the Shares nor the Conversion Shares have been registered under the Securities Act. Purchaser also understands that the Shares are being offered and sold pursuant to an exemption from registration contained in the Securities Act based in part upon Purchaser’s representations contained in the Agreement. Purchaser hereby represents and warrants as follows:

(a) Purchaser Bears Economic Risk. Purchaser has substantial experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its own interests. Purchaser must bear the economic risk of this investment indefinitely unless the Shares (or the Conversion Shares) are registered pursuant to the Securities Act, or an exemption from registration is available. Purchaser understands that the Company has no present intention of registering the Shares, the Conversion Shares or any shares of its Common Stock. Purchaser also understands that there is no assurance that any exemption from registration under the Securities Act will be available and that, even if available, such exemption may not allow Purchaser to transfer all or any portion of the Shares or the Conversion Shares under the circumstances, in the amounts or at the times Purchaser might propose.

(b) Acquisition for Own Account. Purchaser is acquiring the Shares and the Conversion Shares for Purchaser’s own account for investment only, and not with a view towards their distribution.

(c) Purchaser Can Protect Its Interest. Purchaser represents that by reason of its, or of its management’s, business or financial experience, Purchaser has the capacity to protect its own interests in connection with the transactions contemplated in this Agreement, and the Related Agreements. Further, Purchaser is aware of no publication of any advertisement in connection with the transactions contemplated in the Agreement.

(d) Accredited Investor. Purchaser represents that it is an accredited investor within the meaning of Regulation D under the Securities Act.

(e) Company Information. Purchaser has had an opportunity to discuss the Company’s business, management and financial affairs with directors, officers and management of the Company and has had the opportunity to review the Company’s operations

10.

and facilities. Purchaser has also had the opportunity to ask questions of and receive answers from, the Company and its management regarding the terms and conditions of this investment.

(f) Rule 144. Purchaser acknowledges and agrees that the Shares, and, if issued, the Conversion Shares are “restricted securities” as defined in Rule 144 promulgated under the Securities Act as in effect from time to time and must be held indefinitely unless they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser has been advised or is aware of the provisions of Rule 144, which permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public information about the Company, the resale occurring following the required holding period under Rule 144 and the number of shares being sold during any three-month period not exceeding specified limitations.

(g) Residence. If Purchaser is an individual, then Purchaser resides in the state or province identified in the address of Purchaser set forth on Exhibit A; if Purchaser is a partnership, corporation, limited liability company or other entity, then the office or offices of Purchaser in which its investment decision was made is located at the address or addresses of Purchaser set forth on Exhibit A.

(h) Foreign Investors. If Purchaser is not a United States person (as defined by Section 7701(a)(30) of the Code), Purchaser hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in connection with any invitation to subscribe for the Shares or any use of this Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Shares, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any government or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant to the purchase, holding, redemption, sale or transfer of the Shares. The Company’s offer and sale and Purchaser’s subscription and payment for and continued beneficial ownership of the Shares will not violate any applicable securities or other laws of Purchaser’s jurisdiction.

6.3 Successors and Assigns. Except as otherwise expressly provided herein, the provisions hereof shall inure to the benefit of, and be binding upon the parties hereto and their respective successors, assigns, heirs, executors and administrators and shall inure to the benefit of and be enforceable by each person who shall be a holder of the Shares from time to time; provided, however, that prior to the receipt by the Company of adequate written notice of the transfer of any Shares specifying the full name and address of the transferee, the Company may deem and treat the person listed as the holder of such Shares in its records as the absolute owner and holder of such Shares for all purposes.

14.

6.4 Entire Agreement. This Agreement, the exhibits and schedules hereto, the Related Agreements and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard to the subjects hereof and no party shall be liable or bound to any other in any manner by any oral or written representations, warranties, covenants and agreements except as specifically set forth herein and therein. Each party expressly represents and warrants that it is not relying on any oral or written representations, warranties, covenants or agreements outside of the Agreement and the Related Agreements.

6.5 Severability.

6.6 Amendment and Waiver.

(a) Except as otherwise expressly provided for in Section 2.3, this Agreement may be amended or modified only upon the written consent of the Company and holders of at least a majority of the then outstanding Shares (treated as if converted and including any Conversion Shares into which the then outstanding Shares have been converted that have not been sold to the public).

(b) The obligations of the Company and the rights of the holders of the Shares and the Conversion Shares under the Agreement may be waived only with the written consent of the holders of at least a majority of the then outstanding Shares (treated as if converted and including any Conversion Shares into which the then outstanding Shares have been converted that have not been sold to the public).

6.7 Delays or Omissions. It is agreed that no delay or omission to exercise any right, power or remedy accruing to any party, upon any breach, default or noncompliance by another party under this Agreement, the Related Agreements or the Restated Charter, shall impair any such right, power or remedy, nor shall it be construed to be a waiver of any such breach, default or noncompliance, or any acquiescence therein, or of or in any similar breach, default or noncompliance thereafter occurring.

16.

6.10 Expenses.

6.12 Titles and Subtitles. The titles of the sections and subsections of the Agreement are for convenience of reference only and are not to be considered in construing this Agreement.

6.13 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be an original, but all of which together shall constitute one instrument.

6.14 Broker’s Fees. Each party hereto represents and warrants that no agent, broker, investment banker, person or firm acting on behalf of or under the authority of such party hereto is or will be entitled to any broker’s or finder’s fee or any other commission directly or indirectly in connection with the transactions contemplated herein.

6.15 Exculpation Among Purchasers. Each Purchaser acknowledges that it is not relying upon any person, firm, or corporation, other than the Company and its officers and directors, in making its investment or decision to invest in the Company. Each Purchaser agrees that no Purchaser nor the respective controlling persons, officers, directors, partners, agents, or employees of any Purchaser shall be liable to any other Purchaser for any action heretofore or hereafter taken or omitted to be taken by any of them in connection with the Shares and Conversion Shares.

6.16 Pronouns. All pronouns contained herein, and any variations thereof, shall be deemed to refer to the masculine, feminine or neutral, singular or plural, as to the identity of the parties hereto may require.
