The outline of the Premises is set forth in Exhibit A attached hereto. The outline of the "Building" and the "Project," as those terms are defined in Section 1.1.2 below, are further depicted on the Site Plan attached hereto as Exhibit A-1. The parties hereto agree that the lease of the Premises is upon and subject to the terms, covenants and conditions herein set forth, and Tenant covenants as a material part of the consideration for this Lease to keep and perform each and all of such terms, covenants and conditions by it to be kept and performed and that this Lease is made upon the condition of such performance. The parties hereto hereby acknowledge that the purpose of Exhibit A is to show the approximate location of the Premises only, and such Exhibit is not meant to constitute an agreement, representation or warranty as to the construction of the Premises, the precise area thereof or the specific location of the "Common Areas," as that term is defined in Section 1.1.3, below, or the elements thereof or of the accessways to the Premises or the "Project," as that term is defined in Section 1.1.2, below. Except as specifically set forth in this Lease and in the Tenant Work Letter attached hereto as Exhibit B (the "Tenant Work Letter"), Landlord shall not be obligated to provide or pay for any improvement work or services related to the improvement of the Premises. Tenant also acknowledges that neither Landlord nor any agent of Landlord has made any representation or warranty regarding the condition of the Premises, the Building or the Project or with respect to the suitability of any of the foregoing for the conduct of Tenant's business, except as specifically set forth in this Lease and the Tenant Work Letter (including, without limitation, Landlord’s obligation to cause the completion of the Landlord Work (as defined in Section 1.1 of the Tenant Work Letter) and correct any deficiencies in the construction of the Landlord Work, as and to the extent set forth in the Tenant Work Letter). The taking of possession of the Premises by Tenant shall conclusively establish that the Premises and the Building were at such time in good and sanitary order, condition and repair, except with respect to deficiencies and latent defects to the extent provided in the Tenant Work Letter. Upon the date Tenant accepts possession of the Premises, the Building Systems shall be in good working condition and repair, and Landlord hereby covenants that the Building Systems shall remain in good working condition for a period of one (1) year following the date Tenant takes possession under this Lease. Notwithstanding anything in this Lease to the contrary, Landlord shall, at Landlord's sole cost and expense (which shall not be deemed an "Operating Expense," as that term is defined in Section 4.2.4), repair or replace any failed or inoperable portion of the Building Systems during such one (1) year period ("Landlord’s One Year Warranty"), provided that the need to repair or replace was not caused by the misuse, misconduct, damage, destruction, omissions, and/or negligence of Tenant, its subtenants and/or assignees, if any, or any company which is acquired, sold or merged with Tenant (collectively, "Tenant Damage"), or by any modifications, Alterations or improvements constructed by or on behalf of Tenant. To the extent repairs which Landlord is required to make pursuant to this Section 1.1.1 are necessitated in part by Tenant Damage, then Tenant shall reimburse Landlord for an equitable proportion of the cost of such repair. In addition, to the extent that as of the delivery of the Premises to Tenant (a) the Premises are not in compliance with applicable laws (including the Americans With Disabilities Act) to the extent required to allow the legal occupancy of the Premises, Landlord shall remedy any such non-compliance at Landlord's sole cost and expense. If as of the date of delivery of the Premises to Tenant the Premises are found to contain any asbestos containing material or other "Hazardous Materials" (as defined in Section, 5.3.1.1 below) in violation of applicable laws, Landlord will remedy such violation of applicable laws at Landlord's sole cost and expense. Following the date the Premises are delivered to Tenant, Tenant shall have access to the Premises, the Building, and the parking areas serving the Building twenty-four) hours per day, seven (7) days per week, every day of the year during the Lease Term, subject to all applicable laws, Landlord’s reasonable access control procedures, and the terms of this Lease.

1.1.3 Common Areas. Tenant shall have the non-exclusive right to use in common with other tenants in the Project, and subject to the rules and regulations referred to in Article 5 of this Lease, those portions of the Project which are provided, from time to time, for use in common by Landlord, Tenant and any other tenants of the Project (such areas, together with such other portions of the Project designated by Landlord, in its discretion, are collectively referred to herein as the "Common Areas"). The Common Areas shall be maintained and operated by Landlord in a condition consistent with other First Class Life Sciences Projects, and the use thereof shall be subject to such reasonable rules, regulations and restrictions as Landlord may make from time to time for all tenants of the Project. Landlord reserves the right to close temporarily, make alterations or additions to, or change the location of elements of the Project and the Common Areas, provided that, in connection therewith, Landlord shall perform such closures, alterations, additions or changes in a commercially reasonable manner and, in connection therewith, shall use commercially reasonable efforts to minimize any material interference with Tenant's use of and access to the Premises, and provided that Tenant’s use of the Premises and parking areas and access thereto is not materially adversely affected thereby.

1.1.4 Outside Delivery Date. In the event that Landlord fails to cause the Premises to be Ready for Occupancy on or before September 1, 2014 (the "Outside Date"), for any reason other than a Force Majeure Delay or a Tenant Delay (as defined and referenced below, respectively), then Tenant's sole and exclusive remedy at law or in equity for Landlord's failure to cause the Premises to be Ready for Occupancy on or prior to the Outside Date shall be to terminate this Lease pursuant to the terms of this Section 1.1.4. If Landlord does not cause the Premises to be Ready for Occupancy on or before the Outside Date, then Tenant shall have the right to deliver a notice to Landlord (an "Outside Date Termination Notice") electing to terminate this Lease effective upon the date (the "Effective Termination Date") occurring five (5) business days following receipt by Landlord of the Outside Date Termination Notice. The Outside Date Termination Notice must be delivered by Tenant to Landlord, if at all, not earlier than the Outside Date (as the same may be extended pursuant to the terms of Section 3.1.3, below) nor later than ten (10) business days after the Outside Date. In the event that Tenant fails to timely deliver the Outside Date Termination Notice to Landlord on or before such ten (10) business days, then Tenant's right to terminate the Lease pursuant to the terms of this Section 1.1.4 shall be deemed terminated and without any further force or effect. In the event that Tenant delivers to Landlord the Outside Date Termination Notice in accordance with the terms of this Section 1.1.4, then this Lease shall automatically terminate and be of no further force or effect, and Landlord and Tenant shall be relieved of their respective obligations under this Lease, as of the Effective Termination Date, provided that, Landlord shall, within thirty (30) days following the Effective Termination Date, return to Tenant the Security Deposit and any prepaid Base Rent paid by Tenant under this Lease. The Scheduled Delivery Date and the Outside Date shall each be extended to the extent of any delays beyond the reasonable control of Landlord, including any delay or delays caused by "Force Majeure," as that term is defined in Section 29.16 of this Lease (a “Force Majeure Delay”), and any "Tenant Delay," as that term is defined in Section 1(j) of the Tenant Work Letter.

1.1.5 No Holdover Obligations. In the event that the Premises are not Ready for Occupancy on or before June 30, 2014 (the "Delivery Delay"), and, as the result of such Delivery Delay Tenant is unable to vacate its existing Premises in the building of the Project located at 000 Xxxx Xxxxx Xxxxxx (the "Existing Space"), then, notwithstanding the terms of Tenant's sublease in such Existing Space (the "Sublease"), or of the lease to which such sublease is subject (the "Prime Lease"), Landlord will not charge any additional "holdover rent" (i.e., any increased rent above the rental rates payable as of the expiration of such lease or sublease) to Tenant under its sublease, or to the tenant under the Prime Lease, for the period from June 20, 2014, through the date the Premises are Ready for Occupancy, nor shall Landlord hold Tenant or the tenant under the Prime Lease liable for any direct or consequential damages arising from some holdover where it is caused by a Delivery Delay.

1.3 Right of First Offer. Landlord hereby grants to the Tenant named in the Summary (the "Original Tenant") and its "Permitted Transferees," as defined in Section 14.8, below, an ongoing right of first offer with respect to the separately demised space directly contiguous to the Premises (the "First Offer Space"). Notwithstanding the foregoing, such first offer right of Tenant shall commence only following the expiration or earlier termination of the existing lease (including any renewals) of the First Offer Space, and such right of first offer shall be subordinate to all existing rights currently held by CytoKinetics, Inc., under its existing Lease in the Project, including any renewal, extension or expansion rights set forth in any such lease, regardless of whether such renewal, extension or expansion rights are executed strictly in accordance with their terms, or pursuant to a lease amendment or a new lease (the "Superior Right Holder") with respect to such First Offer Space. Tenant's right of first offer shall not be applicable during any Option Term. Tenant's right of first offer shall be on the terms and conditions set forth in this Section 1.3.

1.3.1 Procedure for Offer. Landlord shall notify Tenant (the "First Offer Notice") from time to time when the First Offer Space or any portion thereof becomes available for lease to third parties, provided that no Superior Right Holder wishes to lease such space pursuant to such superior right. Pursuant to such First Offer Notice, Landlord shall offer to lease to Tenant the then available First Offer Space. The First Offer Notice shall describe the space so offered to Tenant and shall set forth the "First Offer Rent," as that term is defined in Section 1.3.3 below, and the other economic terms upon which Landlord is willing to lease such space to Tenant.

1.3.2 Procedure for Acceptance. If Tenant wishes to exercise Tenant's right of first offer with respect to the space described in the First Offer Notice, then within ten (10) days of delivery of the First Offer Notice to Tenant, Tenant shall deliver notice to Landlord of Tenant's election to exercise its right of first offer with respect to the entire space described in the First Offer Notice on the terms contained in such notice. If Tenant elects to exercise the right of first offer, such space shall be leased upon the terms and conditions contained in the first offer notice, and otherwise upon all of the terms and conditions of this Lease. If Tenant does not so notify Landlord within the ten (10) day period, then Landlord shall be free to lease the space described in the First Offer Notice to anyone to whom Landlord desires on any terms Landlord desires; provided that, if Landlord desires to lease the space described in the First Offer Notice to a third party for a net effective rent per square foot that is less than 95% of the rent set forth in the First Offer Notice, or fails to enter into a lease upon such terms within six (6) months of the First Offer Notice, then Tenant’s first offer right under this Lease shall revive and Landlord shall comply with the requirements of this Section 1.3 before leasing such space to any third party. Notwithstanding anything to the contrary contained herein, Tenant must elect to exercise its right of first offer, if at all, with respect to all of the space offered by Landlord to Tenant at any particular time, and Tenant may not elect to lease only a portion thereof.

1.3.3 First Offer Space Rent. The "Rent," as that term is defined in Section 4.1, below, payable by Tenant for the First Offer Space (the "First Offer Rent") shall be equal to the "Fair Rental Value", as defined in Section 2.2.2, below, as of the "First Offer Commencement Date," as that term is defined in Section 1.3.5, below.

1.3.4 Construction In First Offer Space. Tenant shall take the First Offer Space in its "as is" condition, subject to any improvement allowance granted as a component of the Fair Rental Value, and the construction of improvements in the First Offer Space shall comply with the terms of Article 8 of this Lease.

1.3.5 Amendment to Lease. If Tenant timely exercises Tenant's right to lease the First Offer Space as set forth herein, Landlord and Tenant shall promptly thereafter execute an amendment to this Lease for such First Offer Space upon the terms and conditions as set forth in the First Offer Notice and this Section 1.3. Tenant shall commence payment of Rent for the First Offer Space, and the term of the First Offer Space shall commence upon the date of delivery of the First Offer Space to Tenant (the "First Offer Commencement Date") and terminate on the date set forth in the First Offer Notice. Failure of either party to enter into such amendment shall not release such party from its obligations with respect to the First Offer Space.

1.3.6 Termination of Right of First Offer. The rights contained in this Section 1.3 shall be personal to the Original Tenant and its Permitted Transferees, and may only be exercised by the Original Tenant or a Permitted Transferee (and not any other assignee, sublessee or other transferee of the Original Tenant's interest in this Lease). The right of first offer granted herein shall terminate as to particular First Offer Space upon the failure by Tenant to exercise its right of first offer with respect to such First Offer Space as offered by Landlord. Tenant shall not have the right to lease First Offer Space, as provided in this Section 1.3, if, as of the date of the attempted exercise of any right of first offer by Tenant, Tenant is in default under this Lease, after the expiration of any applicable notice and cure period.

2.	LEASE TERM; OPTION TERM

2.1 Lease Term. The terms and provisions of this Lease shall be effective as of the date of this Lease. The term of this Lease (the "Lease Term") shall be as set forth in Section 3.1 of the Summary, shall commence on the date set forth in Section 3.2 of the Summary (the "Lease Commencement Date"), and shall terminate on the date set forth in Section 3.3 of the Summary (the "Lease Expiration Date") unless this Lease is sooner terminated as hereinafter provided. For purposes of this Lease, the term "Lease Year" shall mean each consecutive twelve (12) month period during the Lease Term. At any time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in Exhibit C, attached hereto, as a confirmation only of the information set forth therein, which Tenant shall execute and return to Landlord within five (5) business days of receipt thereof.

2.2 Option Term.

2.2.1 Option Right. Landlord hereby grants the Tenant originally named in this Lease (the “Original Tenant”), its Permitted Transferees, or any assignee of Tenant's entire interest in this Lease approved by Landlord in accordance with the terms of Article 14, below, one (1) option to extend the Lease Term for a period of three (3) years (the “Option Term”). Such option to extend shall be exercisable only by written notice delivered by Tenant to Landlord not more than twelve (12) months nor less than nine (9) months prior to the expiration of the initial Lease Term, stating that Tenant is thereby irrevocably exercising its option to lease the Premises during the Option Term. Upon the proper exercise of the option to extend, and provided that, at Landlord’s option, as of the date of delivery of such notice, Tenant is not in default under this Lease, beyond applicable notice and cure periods, and as of the end of the initial Lease Term Tenant is not in default under this Lease, the Lease Term shall be extended for a period of three (3) years. In the event that Tenant fails to timely and appropriately exercise its initial option to extend the Lease Term in accordance with the terms of this Section 2.2, then such option shall automatically terminate and shall be of no further force or effect.

2.2.2 Option Rent. The annual Rent payable by Tenant during the Option Term (the "Option Rent") shall be equal to the "Fair Rental Value," as that term is defined below, for the Premises as of the commencement date of the Option Term. The "Fair Rental Value," as used in this Lease, shall be equal to the annual rent per rentable square foot on a net basis, including all escalations, at which tenants (pursuant to leases consummated within the twelve (12) month period preceding the first day of the Option Term), are leasing non-sublease, non-encumbered, non-equity space which is not significantly greater or smaller in size than the subject space, with a comparable level of improvements (excluding any property that Tenant would be allowed to remove from the Premises at the termination of the Lease), for a comparable lease term, in an arm's length transaction, which comparable space is located in the "Comparable Buildings," as that term is defined in this Section 2.2.2, below (transactions satisfying the foregoing criteria shall be known as the "Comparable Transactions"), taking into consideration the following concessions (the "Concessions"): (a) rental abatement concessions, if any, being granted such tenants in connection with such comparable space; (b) tenant improvements or allowances provided or to be provided for such comparable space, and taking into account the value, if any, of the existing improvements in the subject space, such value to be based upon the age, condition, design, quality of finishes and layout of the improvements and the extent to which the same can be utilized by a general office user other than Tenant; and (c) other reasonable monetary concessions being granted such tenants in connection with such comparable space; provided, however, that in calculating the Fair Rental Value, no consideration shall be given to (i) the fact that Landlord is or is not required to pay a real estate brokerage commission in connection with Tenant's exercise of its right to extend the Lease Term, or the fact that landlords are or are not paying real estate brokerage commissions in connection with such comparable space, and (ii) any period of rental abatement, if any, granted to tenants in comparable transactions in connection with the design, permitting and construction of tenant improvements in such comparable spaces. If the stock of the Guarantor is no longer traded on a national public stock exchange, then the Fair Rental Value shall additionally include a determination as to whether, and if so to what extent, Tenant must provide Landlord with financial security, such as a letter of credit or guaranty, for Tenant's Rent obligations in connection with Tenant's lease of the Premises during the Option Term. Such determination shall be made by reviewing the extent of financial security then generally being imposed in Comparable Transactions from tenants of comparable financial condition and credit history to the then existing financial condition and credit history of Tenant (with appropriate adjustments to account for differences in the then-existing financial condition of Tenant and such other tenants). The Concessions (A) shall be reflected in the effective rental rate (which effective rental rate shall take into consideration the total dollar value of such Concessions as amortized on a straight-line basis over the applicable term of the Comparable Transaction (in which case such Concessions evidenced in the effective rental rate shall not be granted to Tenant)) payable by Tenant, or (B) at Landlord’s election, all such Concessions shall be granted to Tenant in kind. The term “Comparable Buildings” shall mean the Building and those other comparable life sciences buildings which are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation of to the building), quality of construction, level of services and amenities, size and appearance, and are located in South San Francisco, California and the surrounding commercial area. Notwithstanding any provision to the contrary contained in this Section 2.2.2, Landlord and Tenant hereby acknowledge and agree that if there are not a sufficient number of Comparable Transactions with a comparable term to the Option Term to determine the Fair Rental Value for a lease of such duration, then the Fair Rental Value for purposes of Section 2.2.2 shall be equal to that of Comparable Transactions with a term of up to five (5) years, provided that the concessions shall be appropriately prorated on a fractional basis to account for the shorter term of the Option Term.

- 7 -

2.2.3 Determination of Option Rent. In the event Tenant timely and appropriately exercises an option to extend the Lease Term, Landlord shall notify Tenant of Landlord's determination of the Option Rent within thirty (30) days thereafter. If Tenant, on or before the date which is ten (10) days following the date upon which Tenant receives Landlord's determination of the Option Rent, in good faith objects to Landlord's determination of the Option Rent, then Landlord and Tenant shall attempt to agree upon the Option Rent using their best good-faith efforts. If Landlord and Tenant fail to reach agreement within ten (10) days following Tenant's objection to the Option Rent (the "Outside Agreement Date"), then Tenant shall have the right to withdraw its exercise of the option by delivering written notice thereof to Landlord within five (5) days thereafter, in which event Tenant’s right to extend the Lease pursuant to this Section 2.2 shall be of no further force or effect. If Tenant does not withdraw its exercise of the extension option, each party shall make a separate determination of the Option Rent, as the case may be, within ten (10) days after the Outside Agreement Date, and such determinations shall be submitted to arbitration in accordance with Sections 2.2.3.1 through 2.2.3.7, below. If Tenant fails to object to Landlord's determination of the Option Rent within the time period set forth herein, then Tenant shall be deemed to have objected to Landlord's determination of Option Rent.

2.2.3.1 Landlord and Tenant shall each appoint one arbitrator who shall be a real estate appraiser who shall have been active over the five (5) year period ending on the date of such appointment in the appraisal of other class A life sciences buildings located in the South San Francisco market area. The determination of the arbitrators shall be limited solely to the issue of whether Landlord's or Tenant's submitted Option Rent is the closest to the actual Option Rent, taking into account the requirements of Section 2.2.2 of this Lease, as determined by the arbitrators. Each such arbitrator shall be appointed within fifteen (15) days after the Outside Agreement Date. Landlord and Tenant may consult with their selected arbitrators prior to appointment and may select an arbitrator who is favorable to their respective positions. The arbitrators so selected by Landlord and Tenant shall be deemed "Advocate Arbitrators."

2.2.3.2 The two (2) Advocate Arbitrators so appointed shall be specifically required pursuant to an engagement letter within ten (10) days of the date of the appointment of the last appointed Advocate Arbitrator to agree upon and appoint a third arbitrator ("Neutral Arbitrator") who shall be qualified under the same criteria set forth hereinabove for qualification of the two Advocate Arbitrators, except that neither the Landlord or Tenant or either parties' Advocate Arbitrator may, directly or indirectly, consult with the Neutral Arbitrator prior or subsequent to his or her appearance. The Neutral Arbitrator shall be retained via an engagement letter jointly prepared by Landlord's counsel and Tenant’s counsel.

2.2.3.3 The three arbitrators shall, within thirty (30) days of the appointment of the Neutral Arbitrator, reach a decision as to whether the parties shall use Landlord's or Tenant's submitted Option Rent, and shall notify Landlord and Tenant thereof.

- 8 -

2.2.3.4 The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant.

2.2.3.5 If either Landlord or Tenant fails to appoint an Advocate Arbitrator within fifteen (15) days after the Outside Agreement Date, then either party may petition the presiding judge of the Superior Court of San Mateo County to appoint such Advocate Arbitrator subject to the criteria in Section 2.2.3.1 of this Lease, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such Advocate Arbitrator.

2.2.3.6 If the two (2) Advocate Arbitrators fail to agree upon and appoint the Neutral Arbitrator within ten (10) business days after the appointment of the last appointed Advocate Arbitrator, then either party may petition the presiding judge of the Superior Court of San Mateo County to appoint the Neutral Arbitrator, subject to criteria in Section 2.2.3.1 of this Lease, or if he or she refuses to act, either party may petition any judge having jurisdiction over the parties to appoint such arbitrator.

2.2.3.7 The cost of the arbitration shall be paid by Landlord and Tenant equally.

2.2.3.8 In the event that the Option Rent shall not have been determined pursuant to the terms hereof prior to the commencement of the Option Term, Tenant shall be required to pay the Option Rent initially provided by Landlord to Tenant, and upon the final determination of the Option Rent, the payments made by Tenant shall be reconciled with the actual amounts of Option Rent due, and the appropriate party shall make any corresponding payment to the other party.

3. BASE RENT Tenant shall pay, without prior notice or demand, to Landlord or Landlord's agent at the management office of the Project, or, at Landlord's option, at such other place as Landlord may from time to time designate in writing reasonably in advance of such change taking effect, by a check for currency which, at the time of payment, is legal tender for private or public debts in the United States of America, base rent ("Base Rent") as set forth in Section 4 of the Summary, payable in equal monthly installments as set forth in Section 4 of the Summary in advance on or before the first day of each and every calendar month during the Lease Term, without any setoff or deduction whatsoever. The Base Rent for the first full month of the Lease Term shall be paid at the time of Tenant's execution of this Lease. If any Rent payment date (including the Lease Commencement Date) falls on a day of the month other than the first day of such month or if any payment of Rent is for a period which is shorter than one month, the Rent for any fractional month shall accrue on a daily basis for the period from the date such payment is due to the end of such calendar month or to the end of the Lease Term at a rate per day which is equal to 1/365 of the applicable annual Rent. All other payments or adjustments required to be made under the terms of this Lease that require proration on a time basis shall be prorated on the same basis.

4.	ADDITIONAL RENT

4.1 General Terms.

4.1.1 Direct Expenses; Additional Rent. In addition to paying the Base Rent specified in Article 3 of this Lease, Tenant shall pay "Tenant's Share" of the annual "Direct Expenses," as those terms are defined in Sections 4.2.6 and 4.2.2 of this Lease, respectively. Such payments by Tenant, together with any and all other amounts payable by Tenant to Landlord pursuant to the terms of this Lease, are hereinafter collectively referred to as the "Additional Rent", and the Base Rent and the Additional Rent are herein collectively referred to as "Rent."

4.1.2 Triple Net Lease. Landlord and Tenant acknowledge that, except as otherwise provided to the contrary in this Lease, it is their intent and agreement that this Lease be a "TRIPLE NET" lease and that as such, the provisions contained in this Lease are intended to pass on to Tenant or reimburse Landlord for the costs and expenses reasonably associated with this Lease, the Building and the Project, and Tenant's operation therefrom. To the extent such costs and expenses payable by Tenant cannot be charged directly to, and paid by, Tenant, such costs and expenses shall be paid by Landlord but reimbursed by Tenant as Additional Rent.

- 13 -

4.3 Allocation of Direct Expenses. The parties acknowledge that the Building is a part of a multi-building project and that the costs and expenses incurred in connection with the Project (i.e., the Direct Expenses) should be shared between the Building and the other buildings in the Project. Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consist of Operating Expenses and tax Expenses) are determined annually for the Project as a whole, and a portion of the Direct Expenses, which portion shall be determined by Landlord on an equitable basis, shall be allocated to the Building (as opposed to other buildings in the Project). Such portion of Direct Expenses allocated to the Building shall include all Direct Expenses attributable solely to the Building and an equitable portion of the Direct Expenses attributable to the Project as a whole, and shall not include Direct Expenses attributable solely to other buildings in the Project.

4.4 Calculation and Payment of Additional Rent. Tenant shall pay to Landlord, in the manner set forth in Section 4.4.1, below, and as Additional Rent, Tenant's Share of Direct Expenses for each Expense Year.

4.4.1 Statement of Actual Direct Expenses and Payment by Tenant. Landlord shall endeavor to give to Tenant following the end of each Expense Year, a statement (the "Statement") which shall state the Direct Expenses incurred or accrued for such preceding Expense Year, and which shall indicate the amount of Tenant's Share of Direct Expenses. Landlord shall use commercially reasonable efforts to provide such Statement to Tenant on or before April 30 of the calendar year following the applicable Expense Year. Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, by the later of thirty (30) days after receiving such statement or with its next installment of Base Rent due, the full amount of Tenant's Share of Direct Expenses for such Expense Year, less the amounts, if any, paid during such Expense Year as "Estimated Direct Expenses," as that term is defined in Section 4.4.2, below, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant's Share of Direct Expenses, Tenant shall receive a credit in the amount of Tenant's overpayment against Rent next due under this Lease until exhausted, or shall receive a refund of such overpayment to the extent it exceeds the remaining Rent due under the Lease. The failure of Landlord to timely furnish the Statement for any Expense Year shall not prejudice Landlord or Tenant from enforcing its rights under this Article 4, subject to Section 4.1.1, above. Even though the Lease Term has expired and Tenant has vacated the Premises, when the final determination is made of Tenant's Share of Direct Expenses for the Expense Year in which this Lease terminates, Tenant shall immediately pay to Landlord such amount, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant's Share of Direct Expenses, Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of the overpayment. The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term.

4.4.2 Statement of Estimated Direct Expenses. In addition, Landlord shall endeavor to give Tenant a yearly expense estimate statement (the "Estimate Statement") which shall set forth Landlord's reasonable estimate (the "Estimate") of what the total amount of Direct Expenses for the then-current Expense Year shall be and the estimated Tenant's Share of Direct Expenses (the "Estimated Direct Expenses"). The failure of Landlord to timely furnish the Estimate Statement for any Expense Year shall not preclude Landlord from enforcing its rights to collect any Estimated Direct Expenses under this Article 4, nor shall Landlord be prohibited from revising any Estimate Statement or Estimated Direct Expenses theretofore delivered to the extent necessary. Thereafter, Tenant shall pay, with its next installment of Base Rent due, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the last sentence of this Section 4.4.2). Such fraction shall have as its numerator the number of months which have elapsed in such current Expense Year, including the month of such payment, and twelve (12) as its denominator. Until a new Estimate Statement is furnished (which Landlord shall have the right to deliver to Tenant at any time), Tenant shall pay monthly, with the monthly Base Rent installments, an amount equal to one-twelfth (1/12) of the total Estimated Direct Expenses set forth in the previous Estimate Statement delivered by Landlord to Tenant.

4.5 Taxes and Other Charges for Which Tenant Is Directly Responsible. Tenant shall be liable for and shall pay ten (10) days before delinquency, taxes levied against Tenant's equipment, furniture, fixtures and any other personal property located in or about the Premises. If any such taxes on Tenant's equipment, furniture, fixtures and any other personal property are levied against Landlord or Landlord's property or if the assessed value of Landlord's property is increased by the inclusion therein of a value placed upon such equipment, furniture, fixtures or any other personal property and if Landlord pays the taxes based upon such increased assessment, which Landlord shall have the right to do regardless of the validity thereof but only under proper protest if requested by Tenant, Tenant shall upon demand repay to Landlord the taxes so levied against Landlord or the proportion of such taxes resulting from such increase in the assessment, as the case may be.

- 14 -

4.6 Landlord's Books and Records. Notwithstanding anything to the contrary contained in this Lease, if, within ninety (90) days after receipt of a Statement by Tenant, Tenant (i) reasonably disputes any amounts set forth in any Statement described above in this Article 4, and (ii) is not then in monetary or material non-monetary default under this Lease (beyond the expiration of any applicable notice and cure period expressly set forth in this Lease), then Tenant shall have the right to cause Landlord’s books and records to be audited by a nationally recognized firm of certified public accountants reasonably approved by Landlord, at no cost or expense to Landlord, which has prior experience in the review of financial statements and which shall not have provided primary accounting services to Tenant within the immediately preceding three (3) year period and which shall not be retained by Tenant on a contingency fee basis; provided, however, Tenant shall not have the right to perform any such audit more than one (1) time for any Expense Year during the Lease Term. Any audit conducted by or on behalf of Tenant shall be completed in a diligent manner and timely manner (but in any event within two (2) months after Tenant initially disputes the applicable Statement) and shall be performed at Landlord’s office in California during Landlord’s normal business hours and in a manner so as to minimize interference with Landlord’s business operations. Tenant agrees to keep, and to cause Tenant's accountant and its employees to keep, all information revealed by any audit of Landlord’s books and records strictly confidential and not to disclose any such information or permit any such information to be disclosed to anyone other than Landlord, unless compelled to do so by a court of law or any Applicable Law, statute, code, rule or regulation, and Tenant and its accountant and their employees shall sign a confidentiality agreement reflecting such confidentiality. Tenant’s audit shall be limited to an on-site review of Landlord’s general ledger of accounts and supporting documentation. If after such audit, Landlord and Tenant dispute the results of such audit, at Tenant's request, a certified public accounting firm selected by Landlord, and reasonably approved by Tenant, shall, at Tenant's cost, conduct an audit of the relevant Direct Expenses. The amounts payable under this Section 4.6 by Landlord to Tenant or by Tenant to Landlord, as the case may be, will be appropriately adjusted on the basis of such audit (or the audit performed by Tenant, if Landlord does not dispute the results thereof). If such audit (or the audit performed by Tenant, if Landlord does not dispute the results thereof) discloses an overstatement of Direct Expenses in excess of five percent (5%) for such Expense Year, Landlord shall reimburse Tenant for the reasonable cost of both audits; otherwise the cost of such audits shall be borne by Tenant. Any overpayment of Direct Expenses revealed by such audits shall be promptly refunded by Tenant to Landlord. Tenant agrees that this Section 4.6 shall be the sole method to be used by Tenant to dispute the amount of any Direct Expenses payable by Tenant pursuant to the terms of this Lease, and Tenant hereby waives any other rights at law or in equity relating thereto.

Tenant shall comply with, and Tenant's rights and obligations under the Lease and Tenant's use of the Premises shall be subject and subordinate to, all recorded easements, covenants, conditions, and restrictions affecting the Project as of the date of this Lease if Landlord has provided written copies thereof to Tenant.

Furthermore, Landlord shall not be liable under any circumstances for a loss of, or injury to, property or for injury to, or interference with, Tenant's business, including, without limitation, loss of profits, however occurring, through or in connection with or incidental to a failure to furnish any of the services or utilities as set forth in this Article 6.

Tenant acknowledges that the Emergency Generator is currently being used by an existing tenant of the Building, and Tenant's right to the exclusive use of the Emergency Generator set forth in this Section 6.3 shall commence upon the surrender of the Emergency Generator by the existing tenant (estimated to be October 1, 2014).

6.4 Abatement of Rent. In the event that Tenant is prevented from using, and does not use, the Premises or any portion thereof, as a result of (i) any repair, maintenance or alteration performed by Landlord, or which Landlord failed to perform, after the Lease Commencement Date and required by this Lease, which substantially interferes with Tenant's use of the Premises, or (ii) any failure to provide services, utilities or access to the Premises as required by this Lease (either such set of circumstances as set forth in items (i) or (ii), above, to be known as an "Abatement Event"), then Tenant shall give Landlord notice of such Abatement Event, and if such Abatement Event continues for three (3) consecutive business days after Landlord's receipt of any such notice (the "Eligibility Period") then the Base Rent and Tenant's Share of Direct Expenses shall be abated or reduced, as the case may be, after expiration of the Eligibility Period for such time that Tenant continues to be so prevented from using, and does not use for the normal conduct of Tenant's business, the Premises or a portion thereof, in the proportion that the rentable area of the portion of the Premises that Tenant is prevented from using, and does not use, bears to the total rentable area of the Premises; provided, however, in the event that Tenant is prevented from using, and does not use, a portion of the Premises for a period of time in excess of the Eligibility Period and the remaining portion of the Premises is not sufficient to allow Tenant to effectively conduct its business therein, and if Tenant does not conduct its business from such remaining portion, then for such time after expiration of the Eligibility Period during which Tenant is so prevented from effectively conducting its business therein, the Base Rent and Tenant's Share of Direct Expenses for the entire Premises shall be abated for such time as Tenant continues to be so prevented from using, and does not use, the Premises. If, however, Tenant reoccupies any portion of the Premises during such period, the Rent allocable to such reoccupied portion, based on the proportion that the rentable area of such reoccupied portion of the Premises bears to the total rentable area of the Premises, shall be payable by Tenant from the date Tenant reoccupies such portion of the Premises. To the extent an Abatement Event is caused by an event covered by Articles 11 or 13 of this Lease, then Tenant's right to xxxxx rent shall be governed by the terms of such Article 11 or 13, as applicable, and the Eligibility Period shall not be applicable thereto. Such right to xxxxx Base Rent and Tenant's Share of Direct Expenses shall be Tenant's sole and exclusive remedy for rent abatement at law or in equity for an Abatement Event. Except as provided in this Section 6.5, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

11.	DAMAGE AND DESTRUCTION

11.1 Repair of Damage to Premises by Landlord. Tenant shall promptly notify Landlord of any damage to the Premises resulting from fire or any other casualty. If the Premises or any Common Areas serving or providing access to the Premises shall be damaged by fire or other casualty, Landlord shall promptly and diligently, subject to reasonable delays for insurance adjustment or other matters beyond Landlord's reasonable control, and subject to all other terms of this Article 11, restore the Building and Premises and all improvements therein, and such Common Areas. Such restoration shall be to substantially the same condition of the Base Building and the Common Areas prior to the casualty, except for modifications required by zoning and building codes and other laws or by the holder of a mortgage on the Building or Project or any other modifications to the Common Areas deemed desirable by Landlord, which are consistent with the character of the Project, provided that access to the Premises and Tenant's parking rights hereunder shall not be materially impaired. Landlord shall not be liable for any inconvenience or annoyance to Tenant or its visitors, or injury to Tenant's business resulting in any way from such damage or the repair thereof; provided however, that if such fire or other casualty shall have damaged the Premises or Common Areas necessary to Tenant's occupancy, and the Premises or any portion thereof are not occupied by Tenant as a result thereof, then during the time and to the extent the Premises are unfit for occupancy, the Rent shall be abated in proportion to the ratio that the amount of rentable square feet of the Premises which is unfit for occupancy for the purposes permitted under this Lease bears to the total rentable square feet of the Premises.

11.2 Landlord's Option to Repair. Notwithstanding the terms of Section 11.1 of this Lease, Landlord may elect not to rebuild and/or restore the Premises, Building and/or Project, and instead terminate this Lease, by notifying Tenant in writing of such termination within sixty (60) days after the date of discovery of the damage, such notice to include a termination date giving Tenant sixty (60) days to vacate the Premises, but Landlord may so elect only if the Building or Project shall be damaged by fire or other casualty or cause in a manner that affect the use of the Premises, and one or more of the following conditions is present: (i) in Landlord's reasonable judgment, repairs cannot reasonably be completed within one hundred eighty (180) days after the date of discovery of the damage (when such repairs are made without the payment of overtime or other premiums); (ii) the holder of any mortgage on the Building or Project or ground lessor with respect to the Building or Project shall require that the insurance proceeds or any portion thereof be used to retire the mortgage debt, or shall terminate the ground lease, as the case may be; (iii) the damage is not fully covered by Landlord's insurance policies (together with applicable deductible amounts); or (iv) the damage occurs during the last twelve (12) months of the Lease Term; provided, however, that if Landlord does not elect to terminate this Lease pursuant to Landlord's termination right as provided above, and the repairs cannot reasonably be completed within one hundred eighty (180) days after being commenced, Tenant may elect, no earlier than sixty (60) days after the date of the damage and not later than ninety (90) days after the date of such damage, to terminate this Lease by written notice to Landlord effective as of the date specified in the notice, which date shall not be less than thirty (30) days nor more than sixty (60) days after the date such notice is given by Tenant. Further, if repairs are not actually by the later of (a) one hundred eighty (180) days of the date of damage, or (b) thirty (30) days after the estimated date of completion given by Landlord to Tenant within sixty (60) days after the date of the damage, Tenant may terminate this Lease by written notice to Landlord. Notwithstanding the provisions of this Section 11.2, Tenant shall have the right to terminate this Lease under this Section 11.2 only if each of the following conditions is satisfied: (a) the damage to the Project by fire or other casualty was not caused by the gross negligence or intentional act of Tenant or its partners or subpartners and their respective officers, agents, servants, employees, and independent contractors; (b) Tenant is not then in default under this Lease beyond applicable notice and cure periods; (c) as a result of the damage, Tenant cannot reasonably conduct business from substantially all of the Premises; and, (d) as a result of the damage to the Project, Tenant does not occupy or use the Premises or a material portion thereof.

- 26 -

11.3 Waiver of Statutory Provisions. The provisions of this Lease, including this Article 11, constitute an express agreement between Landlord and Tenant with respect to any and all damage to, or destruction of, all or any part of the Premises, the Building or the Project, and any statute or regulation of the State of California, including, without limitation, Sections 1932(2) and 1933(4) of the California Civil Code, with respect to any rights or obligations concerning damage or destruction in the absence of an express agreement between the parties, and any other statute or regulation, now or hereafter in effect, shall have no application to this Lease or any damage or destruction to all or any part of the Premises, the Building or the Project.

12. NONWAIVER No provision of this Lease shall be deemed waived by either party hereto unless expressly waived in a writing signed thereby. The waiver by either party hereto of any breach of any term, covenant or condition herein contained shall not be deemed to be a waiver of any subsequent breach of same or any other term, covenant or condition herein contained. The subsequent acceptance of Rent hereunder by Landlord shall not be deemed to be a waiver of any preceding breach by Tenant of any term, covenant or condition of this Lease, other than the failure of Tenant to pay the particular Rent so accepted, regardless of Landlord's knowledge of such preceding breach at the time of acceptance of such Rent. No acceptance of a lesser amount than the Rent herein stipulated shall be deemed a waiver of Landlord's right to receive the full amount due, nor shall any endorsement or statement on any check or payment or any letter accompanying such check or payment be deemed an accord and satisfaction, and Landlord may accept such check or payment without prejudice to Landlord's right to recover the full amount due. No receipt of monies by Landlord from Tenant after the termination of this Lease shall in any way alter the length of the Lease Term or of Tenant's right of possession hereunder, or after the giving of any notice shall reinstate, continue or extend the Lease Term or affect any notice given Tenant prior to the receipt of such monies, it being agreed that after the service of notice or the commencement of a suit, or after final judgment for possession of the Premises, Landlord may receive and collect any Rent due, and the payment of said Rent shall not waive or affect said notice, suit or judgment.

13. CONDEMNATION If the whole or any material part of the Premises, Building or Project or parking areas serving the Project shall be taken by power of eminent domain or condemned by any competent authority for any public or quasi-public use or purpose, or if any adjacent property or street shall be so taken or condemned, or reconfigured or vacated by such authority in such manner as to require the use, reconstruction or remodeling of any part of the Premises, Building or Project, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, , and in any such case the remainder of the Building, Project, or Premises is not suitable for continued use by Tenant for the uses permitted hereunder, Landlord or Tenant shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority. Tenant shall not because of such taking assert any claim against Landlord or the authority for any compensation because of such taking and Landlord shall be entitled to the entire award or payment in connection therewith, except that Tenant shall have the right to file any separate claim available to Tenant for any taking of Tenant's personal property and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the terms of this Lease, and for moving expenses, so long as such claims do not diminish the award available to Landlord, its ground lessor with respect to the Building or Project or its mortgagee, and such claim is payable separately to Tenant. All Rent shall be apportioned as of the date of such termination. If any part of the Premises shall be taken, and this Lease shall not be so terminated, the Rent shall be proportionately abated. Tenant hereby waives any and all rights it might otherwise have pursuant to Section 1265.130 of The California Code of Civil Procedure. Notwithstanding anything to the contrary contained in this Article 13, in the event of a temporary taking of all or any portion of the Premises for a period of one hundred and eighty (180) days or less, then this Lease shall not terminate but the Base Rent and the Additional Rent shall be abated for the period of such taking in proportion to the ratio that the amount of rentable square feet of the Premises taken bears to the total rentable square feet of the Premises. Landlord shall be entitled to receive the entire award made in connection with any such temporary taking, other than any award payable to Tenant for loss of use of the Premises (provided Landlord’s award is not reduced thereby).

- 27 -

14.	ASSIGNMENT AND SUBLETTING

14.1 Transfers. Tenant shall not, without the prior written consent of Landlord, assign, mortgage, pledge, hypothecate, encumber, or permit any lien to attach to, or otherwise transfer, this Lease or any interest hereunder, permit any assignment, or other transfer of this Lease or any interest hereunder by operation of law, sublet the Premises or any part thereof, or enter into any license or concession agreements or otherwise permit the occupancy or use of the Premises or any part thereof by any persons other than Tenant and its employees and contractors (all of the foregoing are hereinafter sometimes referred to collectively as "Transfers" and any person to whom any Transfer is made or sought to be made is hereinafter sometimes referred to as a "Transferee"). If Tenant desires Landlord's consent to any Transfer, Tenant shall notify Landlord in writing, which notice (the "Transfer Notice") shall include (i) the proposed effective date of the Transfer, which shall not be less than thirty (30) days nor more than one hundred eighty (180) days after the date of delivery of the Transfer Notice, (ii) a description of the portion of the Premises to be transferred (the "Subject Space"), (iii) all of the terms of the proposed Transfer and the consideration therefor, including calculation of the "Transfer Premium", as that term is defined in Section 14.3 below, in connection with such Transfer, the name and address of the proposed Transferee, and a copy of all existing executed and/or proposed documentation pertaining to the proposed Transfer, and (iv) current financial statements of the proposed Transferee certified by an officer, partner or owner thereof, business credit and personal references and history of the proposed Transferee and any other information reasonably required by Landlord which will enable Landlord to determine the financial responsibility, character, and reputation of the proposed Transferee, nature of such Transferee's business and proposed use of the Subject Space. Any Transfer for which Landlord's prior written consent is required under this Article 14, and which is made without Landlord's prior written consent shall, at Landlord's option, be null, void and of no effect, and shall, at Landlord's option, constitute a default by Tenant under this Lease. Whether or not Landlord consents to any proposed Transfer, Tenant shall pay Landlord's reasonable review and processing fees, as well as any reasonable professional fees (including, without limitation, attorneys', accountants', architects', engineers' and consultants' fees) incurred by Landlord, within thirty (30) days after written request by Landlord, provided than in no event shall such fees and costs exceed $3,000 for a Transfer.

14.2 Landlord's Consent. Landlord shall not unreasonably withhold, condition or delay its consent to any proposed Transfer of the Subject Space to the Transferee on the terms specified in the Transfer Notice. Without limitation as to other reasonable grounds for withholding consent, the parties hereby agree that it shall be reasonable under this Lease and under any applicable law for Landlord to withhold consent to any proposed Transfer where one or more of the following apply:

14.2.1 The Transferee is of a character or reputation or engaged in a business which is not consistent with the quality of the Building or the Project;

14.2.2 The Transferee is either a governmental agency or instrumentality thereof;

14.2.3 The Transferee is not a party of reasonable financial worth and/or financial stability in light of the responsibilities to be undertaken in connection with the Transfer on the date consent is requested (and considering any proposed guarantor provided in connection therewith).

If Landlord consents to any Transfer pursuant to the terms of this Section 14.2 (and does not exercise any recapture rights Landlord may have under Section 14.4 of this Lease), Tenant may within six (6) months after Landlord's consent, but not later than the expiration of said six-month period, enter into such Transfer of the Premises or portion thereof, upon substantially the same terms and conditions as are set forth in the Transfer Notice furnished by Tenant to Landlord pursuant to Section 14.1 of this Lease, provided that if there are any changes in the terms and conditions from those specified in the Transfer Notice such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, Tenant shall again submit the Transfer to Landlord for its approval and other action under this Article 14 (including Landlord's right of recapture, if any, under Section 14.4 of this Lease). Notwithstanding anything to the contrary in this Lease, if Tenant or any proposed Transferee claims that Landlord has unreasonably withheld or delayed its consent under Section 14.2 or otherwise has breached or acted unreasonably under this Article 14, their sole remedies shall be a suit for contract damages (other than damages for injury to, or interference with, Tenant's business including, without limitation, loss of profits, however occurring) or declaratory judgment and an injunction for the relief sought, and Tenant hereby waives all other remedies, including, without limitation, any right at law or equity to terminate this Lease, on its own behalf and, to the extent permitted under all applicable laws, on behalf of the proposed Transferee.

- 28 -

14.3 Transfer Premium. If Landlord consents to a Transfer, as a condition thereto which the parties hereby agree is reasonable, Tenant shall pay to Landlord fifty percent (50%) of any "Transfer Premium," as that term is defined in this Section 14.3, received by Tenant from such Transferee. "Transfer Premium" shall mean all rent, additional rent or other consideration payable by such Transferee in connection with the Transfer in excess of the Rent and Additional Rent payable by Tenant under this Lease during the term of the Transfer on a per rentable square foot basis if less than all of the Premises is transferred, and after deduction of (i) any costs of improvements made to the Subject Space in connection with such Transfer, (ii) brokerage commissions paid in connection with such Transfer, (iii) reasonable legal fees incurred in connection with such Transfer, and (iv) other concessions provided to the transferee. "Transfer Premium" shall also include, but not be limited to, key money, bonus money or other cash consideration paid by Transferee to Tenant in connection with such Transfer, and any payment in excess of fair market value for services rendered by Tenant to Transferee or for assets, fixtures, inventory, equipment, or furniture transferred by Tenant to Transferee in connection with such Transfer. The determination of the amount of Landlord's applicable share of the Transfer Premium shall be made on a monthly basis as rent or other consideration is received by Tenant under the Transfer.

14.4 Landlord's Option as to Subject Space. Notwithstanding anything to the contrary contained in this Article 14, in the event Tenant contemplates a Transfer which, together with all prior Transfers then remaining in effect, would cause seventy five percent (75%) or more of the Premises to be Transferred for more than fifty percent (50%) of the then remaining Lease Term (taking into account any extension of the Lease Term which has irrevocably exercised by Tenant), Tenant shall give Landlord notice (the "Intention to Transfer Notice") of such contemplated Transfer (whether or not the contemplated Transferee or the terms of such contemplated Transfer have been determined). The Intention to Transfer Notice shall specify the portion of and amount of rentable square feet of the Premises which Tenant intends to Transfer (the "Contemplated Transfer Space"), the contemplated date of commencement of the Contemplated Transfer (the "Contemplated Effective Date"), and the contemplated length of the term of such contemplated Transfer, and shall specify that such Intention to Transfer Notice is delivered to Landlord pursuant to this Section 14.4 in order to allow Landlord to elect to recapture the Contemplated Transfer Space. Thereafter, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any Intention to Transfer Notice, to recapture the Contemplated Transfer Space. Such recapture shall cancel and terminate this Lease with respect to such Contemplated Transfer Space as of the Contemplated Effective Date. In the event of a recapture by Landlord, if this Lease shall be canceled with respect to less than the entire Premises, the Rent reserved herein shall be prorated on the basis of the number of rentable square feet retained by Tenant in proportion to the number of rentable square feet contained in the Premises, and this Lease as so amended shall continue thereafter in full force and effect, and upon request of either party, the parties shall execute written confirmation of the same. If Landlord declines, or fails to elect in a timely manner, to recapture such Contemplated Transfer Space under this Section 14.4, then, subject to the other terms of this Article 14, for a period of nine (9) months (the "Nine Month Period") commencing on the last day of such thirty (30) day period, Landlord shall not have any right to recapture the Contemplated Transfer Space with respect to any Transfer made during the Nine Month Period, provided that any such Transfer is substantially on the terms set forth in the Intention to Transfer Notice, and provided further that any such Transfer shall be subject to the remaining terms of this Article 14. If such a Transfer is not so consummated within the Nine Month Period (or if a Transfer is so consummated, then upon the expiration of the term of any Transfer of such Contemplated Transfer Space consummated within such Nine Month Period), Tenant shall again be required to submit a new Intention to Transfer Notice to Landlord with respect any contemplated Transfer, as provided above in this Section 14.4. Notwithstanding the foregoing, Landlord’s recapture right under this Section 14.4 shall not apply to a transfer to a Permitted Transferee pursuant to Section 14.8 below, nor to a transfer occurring solely by reason of a change in control of Tenant which is for a bona fide business purpose and not to evade the subleasing and assignment restrictions of this Lease.

- 29 -

14.5 Effect of Transfer. If Landlord consents to a Transfer, (i) the terms and conditions of this Lease shall in no way be deemed to have been waived or modified, (ii) such consent shall not be deemed consent to any further Transfer by either Tenant or a Transferee, (iii) Tenant shall deliver to Landlord, promptly after execution, an original executed copy of all documentation pertaining to the Transfer in form reasonably acceptable to Landlord, (iv) Tenant shall furnish upon Landlord's request a complete statement, certified by an independent certified public accountant, or Tenant's chief financial officer, setting forth in detail the computation of any Transfer Premium Tenant has derived and shall derive from such Transfer, and (v) no Transfer relating to this Lease or agreement entered into with respect thereto, whether with or without Landlord's consent, shall relieve Tenant or any guarantor of the Lease from any liability under this Lease, including, without limitation, in connection with the Subject Space. Landlord or its authorized representatives shall have the right at all reasonable times to audit the books, records and papers of Tenant relating to any Transfer, and shall have the right to make copies thereof. If the Transfer Premium respecting any Transfer shall be found understated, Tenant shall, within thirty (30) days after demand, pay the deficiency, and if understated by more than two percent (2%), Tenant shall pay Landlord's costs of such audit.

14.6 Additional Transfers. For purposes of this Lease, the term "Transfer" shall also include (i) if Tenant is a partnership, the withdrawal or change, voluntary, involuntary or by operation of law, of fifty percent (50%) or more of the partners, or transfer of fifty percent (50%) or more of partnership interests, within a twelve (12)-month period, or the dissolution of the partnership without immediate reconstitution thereof, and (ii) if Tenant is a closely held corporation (i.e., whose stock is not publicly held and not traded through an exchange or over the counter), (A) the dissolution, merger, consolidation or other reorganization of Tenant or (B) the sale or other transfer of an aggregate of fifty percent (50%) or more of the voting shares of Tenant (other than to immediate family members by reason of gift or death), within a twelve (12)-month period. Notwithstanding the foregoing, the raising of capital by an offering of stock or ownership interest in Tenant will not be deemed a Transfer for purposes of this Lease and will not require Landlord’s consent.

14.7 Occurrence of Default. Any Transfer hereunder shall be subordinate and subject to the provisions of this Lease, and if this Lease shall be terminated during the term of any Transfer, Landlord shall have the right to: (i) treat such Transfer as cancelled and repossess the Subject Space by any lawful means, or (ii) require that such Transferee attorn to and recognize Landlord as its landlord under any such Transfer. If Tenant shall be in default under this Lease, Landlord is hereby irrevocably authorized, as Tenant's agent and attorney-in-fact, to direct any Transferee to make all payments under or in connection with the Transfer directly to Landlord (which Landlord shall apply towards Tenant's obligations under this Lease) until such default is cured. Such Transferee shall rely on any representation by Landlord that Tenant is in default hereunder, without any need for confirmation thereof by Tenant. Upon any assignment, the assignee shall assume in writing all obligations and covenants of Tenant thereafter to be performed or observed under this Lease. No collection or acceptance of rent by Landlord from any Transferee shall be deemed a waiver of any provision of this Article 14 or the approval of any Transferee or a release of Tenant from any obligation under this Lease, whether theretofore or thereafter accruing. In no event shall Landlord's enforcement of any provision of this Lease against any Transferee be deemed a waiver of Landlord's right to enforce any term of this Lease against Tenant or any other person. If Tenant's obligations hereunder have been guaranteed, Landlord's consent to any Transfer shall not be effective unless the guarantor also consents to such Transfer.

14.8 Non-Transfers. Notwithstanding anything to the contrary contained in this Article 14, neither (i) an assignment to a transferee of all or substantially all of the stock or assets of Tenant, (ii) an assignment to a transferee which is the resulting entity of a merger or consolidation of Tenant with another entity, (iii) a transfer of the shares of Tenant's stock in the ordinary course of business, (iv) an initial public offering of Tenant's stock on a nationally recognized stock exchange, nor (v) an assignment or subletting of all or a portion of the Premises to an affiliate of Tenant (an "Affiliate") (an entity which is controlled by, controls, or is under common control with, Tenant), shall be deemed a Transfer under this Article 14, provided that Tenant notifies Landlord of any such transaction, assignment or sublease, or such affiliate, as the case may be, and promptly supplies Landlord with any documents or information requested by Landlord regarding such assignment or sublease or such affiliate, and further provided that such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease. Items (i) through (v) shall be referred to herein as a "Permitted Transfer" and any person or entity to whom the Premises is subleased to or this Lease is assigned to pursuant to a Permitted Transfer shall be referred to herein as a "Permitted Transferee". An Affiliate to whom this Lease is assigned to shall be referred to herein as an "Affiliate Assignee". "Control," as used in this Section 14.8, shall mean the ownership, directly or indirectly, of at least fifty-one percent (51%) of the voting securities of, or possession of the right to vote, in the ordinary direction of its affairs, of at least fifty-one percent (51%) of the voting interest in, any person or entity. No such permitted assignment or subletting shall serve to release Tenant from any of its obligations under this Lease. . 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.

- 30 -

15.	SURRENDER OF PREMISES; OWNERSHIP AND REMOVAL OF TRADE FIXTURES

15.1 Surrender of Premises. No act or thing done by Landlord or any agent or employee of Landlord during the Lease Term shall be deemed to constitute an acceptance by Landlord of a surrender of the Premises unless such intent is specifically acknowledged in writing by Landlord. The delivery of keys to the Premises to Landlord or any agent or employee of Landlord shall not constitute a surrender of the Premises or effect a termination of this Lease, whether or not the keys are thereafter retained by Landlord, and notwithstanding such delivery Tenant shall be entitled to the return of such keys at any reasonable time upon request until this Lease shall have been properly terminated. The voluntary or other surrender of this Lease by Tenant, whether accepted by Landlord or not, or a mutual termination hereof, shall not work a merger, and at the option of Landlord shall operate as an assignment to Landlord of all subleases or subtenancies affecting the Premises or terminate any or all such sublessees or subtenancies.

15.2 Removal of Tenant Property by Tenant. Upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, subject to the provisions of this Article 15, quit and surrender possession of the Premises to Landlord in as good order and condition as when Tenant took possession and as thereafter improved by Landlord and/or Tenant, reasonable wear and tear and repairs which are specifically made the responsibility of Landlord hereunder excepted. Upon such expiration or termination, Tenant shall, without expense to Landlord, remove or cause to be removed from the Premises all debris and rubbish, and such items of furniture, equipment, Tenant's business equipment and trade-fixtures, free-standing cabinet work, movable partitions and other articles of personal property owned by Tenant or installed or placed by Tenant at its expense in the Premises, and such similar articles of any other persons claiming under Tenant, as Landlord may, in its sole discretion, require to be removed, and Tenant shall repair at its own expense all damage to the Premises and Building resulting from such removal.

15.3 Environmental Assessment. In connection with its surrender of the Premises, Tenant shall submit to Landlord, at least one hundred twenty (120) days prior to the expiration date of this Lease (or in the event of an earlier termination of this Lease, as soon as reasonably possible following such termination), an environmental Assessment of the Premises by a competent and experienced environmental engineer or engineering firm reasonably satisfactory to Landlord (pursuant to a contract approved by Landlord and providing that Landlord can rely on the Environmental Assessment), which (i) evidences that the Premises are in a clean and safe condition and free and clear of any Hazardous Materials; and (ii) includes a review of the Premises by an environmental consultant for asbestos, mold, fungus, spores, and other moisture conditions, on-site chemical use, and lead-based paint. If such Environmental Assessment reveals that remediation or Clean-up is required under any Environmental Laws, and for which Tenant is responsible under this Lease, Tenant shall submit a remediation plan prepared by a recognized environmental consultant and shall be responsible for all costs of remediation and Clean-up, as more particularly provided in Section 5.3, above.

15.4 Condition of the Building and Premises Upon Surrender. In addition to the above requirements of this Article 15, upon the expiration of the Lease Term, or upon any earlier termination of this Lease, Tenant shall, surrender the Premises with Tenant having complied with all of Tenant’s obligations under this Lease, including those relating to improvement, repair, maintenance, compliance with law, testing and other related obligations of Tenant set forth in Article 7 of this Lease. In the event that the Building and Premises shall be surrendered in a condition which does not comply with the terms of this Section 15.4, because Tenant failed to comply with its obligations set forth in Lease, then following thirty (30) days notice to Tenant, during which thirty (30) day period Tenant shall have the right to cure such noncompliance, Landlord shall be entitled to expend all reasonable costs in order to cause the same to comply with the required condition upon surrender and Tenant shall immediately reimburse Landlord for all such costs upon notice and Tenant shall be deemed during the period that Tenant or Landlord, as the case may be, perform obligations relating to the Surrender Improvements to be in holdover under Article 16 of this Lease.

- 31 -

16. HOLDING OVER If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with the express or implied consent of Landlord, such tenancy shall be from month-to-month only, and shall not constitute a renewal hereof or an extension for any further term. If Tenant holds over after the expiration of the Lease Term of earlier termination thereof, without the express or implied consent of Landlord, such tenancy shall be deemed to be a tenancy by sufferance only, and shall not constitute a renewal hereof or an extension for any further term. In either case, Rent shall be payable at a monthly rate equal to 150% of the Rent applicable during the last rental period of the Lease Term under this Lease. Such month-to-month tenancy or tenancy by sufferance, as the case may be, shall be subject to every other applicable term, covenant and agreement contained herein. Nothing contained in this Article 16 shall be construed as consent by Landlord to any holding over by Tenant, and Landlord expressly reserves the right to require Tenant to surrender possession of the Premises to Landlord as provided in this Lease upon the expiration or other termination of this Lease. The provisions of this Article 16 shall not be deemed to limit or constitute a waiver of any other rights or remedies of Landlord provided herein or at law. If Tenant fails to surrender the Premises upon the termination or expiration of this Lease, in addition to any other liabilities to Landlord accruing therefrom, Tenant shall protect, defend, indemnify and hold Landlord harmless from all loss, costs (including reasonable attorneys' fees) and liability resulting from such failure, including, without limiting the generality of the foregoing, any claims made by any succeeding tenant founded upon such failure to surrender and any lost profits to Landlord resulting therefrom.

17. ESTOPPEL CERTIFICATES Within ten (10) business days following a request in writing by Landlord, Tenant shall execute, acknowledge and deliver to Landlord an estoppel certificate, which, as submitted by Landlord, shall be substantially in the form of Exhibit D, attached hereto (or such other form as may be required by any prospective mortgagee or purchaser of the Project, or any portion thereof), indicating therein any exceptions thereto that may exist at that time (and with such changes as may be required so that the statements therein are true as of the date of delivery), and shall also contain any other information reasonably requested by Landlord or Landlord's mortgagee or prospective mortgagee. Any such certificate may be relied upon by any prospective mortgagee or purchaser of all or any portion of the Project. Tenant shall execute and deliver whatever other instruments may be reasonably required for such purposes. At any time during the Lease Term, within ten (10) business days after request therefor, Landlord may require Tenant to provide Landlord with a current financial statement and financial statements of the two (2) years prior to the current financial statement year (provided that such statements shall not be required if Tenant’s stock is traded on a public exchange and financial statements are publicly available). Such statements shall be prepared in accordance with generally accepted accounting principles and, if such is the normal practice of Tenant, shall be audited by an independent certified public accountant. Failure of Tenant to timely execute, acknowledge and deliver such estoppel certificate or other instruments shall constitute an acceptance of the Premises and an acknowledgment by Tenant that statements included in the estoppel certificate are true and correct, without exception. Landlord shall keep such financial statements confidential and may only disclose them to Landlord’s current or prospective lenders purchasers, investors, and accountants, and only on the condition that they agree to keep such statements confidential.

18. SUBORDINATION Landlord represents and warrants to Tenant that the Building and Project are not currently subject to any existing ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or similar encumbrance. This Lease shall be subject and subordinate to all future ground or underlying leases of the Building or Project and to the lien of any mortgage, trust deed or other encumbrances now or hereafter in force against the Building or Project or any part thereof, if any, and to all renewals, extensions, modifications, consolidations and replacements thereof, and to all advances made or hereafter to be made upon the security of such mortgages or trust deeds, unless the holders of such mortgages, trust deeds or other encumbrances, or the lessors under such ground lease or underlying leases, require in writing that this Lease be superior thereto (collectively, the “Superior Holders”); provided, however, that in consideration of and a condition precedent to Tenant’s agreement to subordinate this Lease to any future mortgage, trust deed or other encumbrances, shall be the receipt by Tenant of a subordination non-disturbance and attornment agreement in the standard form provided by such Superior Holders, which requires such Superior Holder to accept this lease, and not to disturb tenant’s possession, so long as an event of default has not occurred and be continuing executed by Landlord and the appropriate Superior Holder. Tenant covenants and agrees in the event any proceedings are brought for the foreclosure of any such mortgage or deed in lieu thereof (or if any ground lease is terminated), to attorn, without any deductions or set-offs whatsoever, to the lienholder or purchaser or any successors thereto upon any such foreclosure sale or deed in lieu thereof (or to the ground lessor), if so requested to do so by such purchaser or lienholder or ground lessor, and to recognize such purchaser or lienholder or ground lessor as the lessor under this Lease, provided such lienholder or purchaser or ground lessor shall agree to accept this Lease and not disturb Tenant's occupancy, so long as Tenant timely pays the rent and observes and performs the terms, covenants and conditions of this Lease to be observed and performed by Tenant. Landlord's interest herein may be assigned as security at any time to any lienholder. Tenant shall, within ten (10) business days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm the subordination or superiority of this Lease to any such mortgages, trust deeds, ground leases or underlying leases. Tenant waives the provisions of any current or future statute, rule or law which may give or purport to give Tenant any right or election to terminate or otherwise adversely affect this Lease and the obligations of the Tenant hereunder in the event of any foreclosure proceeding or sale.

19.	DEFAULTS; REMEDIES

19.1 Events of Default. The occurrence of any of the following shall constitute a default of this Lease by Tenant (and if such default is not timely cured, as and to the extent herein permitted, such default shall constitute a “Default” under this Lease):

19.1.1 Any failure by Tenant to pay any Rent or any other charge required to be paid under this Lease, or any part thereof, when due unless such failure is cured within five (5) business days after notice; or

19.1.2 Except where a specific time period is otherwise set forth for Tenant's performance in this Lease, in which event the failure to perform by Tenant within such time period shall be a default by Tenant under this Section 19.1.2, any failure by Tenant to observe or perform any other provision, covenant or condition of this Lease to be observed or performed by Tenant where such failure continues for thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of such default is such that the same cannot reasonably be cured within a thirty (30) day period, Tenant shall not be deemed to be in default if it diligently commences such cure within such period and thereafter diligently proceeds to rectify and cure such default; or

19.1.3 The failure by Tenant to observe or perform according to the provisions of Section 5.1 or 5.2, or Articles 14, 17 or 18 of this Lease where such failure continues for more than five (5) business days after notice from Landlord,

The notice periods provided herein are in lieu of, and not in addition to, any notice periods provided by law.

19.2 Remedies Upon Default. Upon the occurrence of any Default by Tenant, Landlord shall have, in addition to any other remedies available to Landlord at law or in equity (all of which remedies shall be distinct, separate and cumulative), the option to pursue any one or more of the following remedies, each and all of which shall be cumulative and nonexclusive, without any notice or demand whatsoever.

19.2.1 Terminate this Lease, in which event Tenant shall immediately surrender the Premises to Landlord, and if Tenant fails to do so, Landlord may, without prejudice to any other remedy which it may have for possession or arrearages in rent, enter upon and take possession of the Premises and expel or remove Tenant and any other person who may be occupying the Premises or any part thereof, without being liable for prosecution or any claim or damages therefor; and Landlord may recover from Tenant the following:

(i) The worth at the time of award of the unpaid rent which has been earned at the time of such termination; plus

(ii) The worth at the time of award of the amount by which the unpaid rent which would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

- 33 -

(iii) The worth at the time of award of the amount by which the unpaid rent for the balance of the Lease Term after the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; plus

(iv) Any other amount necessary to compensate Landlord for all the detriment proximately caused by Tenant's failure to perform its obligations under this Lease or which in the ordinary course of things would be likely to result therefrom, specifically including but not limited to, brokerage commissions and advertising expenses incurred, expenses of remodeling the Premises or any portion thereof for a new tenant, whether for the same or a different use, and any special concessions made to obtain a new tenant; and

(v) At Landlord's election, such other amounts in addition to or in lieu of the foregoing as may be permitted from time to time by applicable law.

The term "rent" as used in this Section 19.2 shall be deemed to be and to mean all sums of every nature required to be paid by Tenant pursuant to the terms of this Lease, whether to Landlord or to others. As used in Sections 19.2.1(i) and (ii), above, the "worth at the time of award" shall be computed by allowing interest at the rate set forth in Article 25 of this Lease, but in no case greater than the maximum amount of such interest permitted by law. As used in Section 19.2.1(iii) above, the "worth at the time of award" shall be computed by discounting such amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of award plus one percent (1%).

19.2.2 Landlord shall have the remedy described in 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 the right to sublet or assign, subject only to reasonable limitations). Accordingly, if Landlord does not elect to terminate this Lease on account of any default by Tenant, Landlord may, from time to time, without terminating this Lease, enforce all of its rights and remedies under this Lease, including the right to recover all rent as it becomes due.

19.2.3 Landlord shall at all times have the rights and remedies (which shall be cumulative with each other and cumulative and in addition to those rights and remedies available under Sections 19.2.1 and 19.2.2, above, or any law or other provision of this Lease), without prior demand or notice except as required by applicable law, to seek any declaratory, injunctive or other equitable relief, and specifically enforce this Lease, or restrain or enjoin a violation or breach of any provision hereof.

19.3 Subleases of Tenant. Whether or not Landlord elects to terminate this Lease on account of any default by Tenant, as set forth in this Article 19, Landlord shall have the right to terminate any and all subleases, licenses, concessions or other consensual arrangements for possession entered into by Tenant and affecting the Premises or may, in Landlord's sole discretion, succeed to Tenant's interest in such subleases, licenses, concessions or arrangements. In the event of Landlord's election to succeed to Tenant's interest in any such subleases, licenses, concessions or arrangements, Tenant shall, as of the date of notice by Landlord of such election, have no further right to or interest in the rent or other consideration receivable thereunder.

19.4 Efforts to Relet. No re-entry or repossession, repairs, maintenance, changes, alterations and additions, reletting, appointment of a receiver to protect Landlord's interests hereunder, or any other action or omission by Landlord shall be construed as an election by Landlord to terminate this Lease or Tenant's right to possession, or to accept a surrender of the Premises, nor shall same operate to release Tenant in whole or in part from any of Tenant's obligations hereunder, unless express written notice of such intention is sent by Landlord to Tenant. Tenant hereby irrevocably waives any right otherwise available under any law to redeem or reinstate this Lease.

20. COVENANT OF QUIET ENJOYMENT Landlord covenants that Tenant, on paying the Rent, charges for services and other payments herein reserved and on keeping, observing and performing all the other terms, covenants, conditions, provisions and agreements herein contained on the part of Tenant to be kept, observed and performed, shall, during the Lease Term, peaceably and quietly have, hold and enjoy the Premises subject to the terms, covenants, conditions, provisions and agreements hereof without interference by any persons lawfully claiming by or through Landlord. The foregoing covenant is in lieu of any other covenant express or implied.

- 34 -

21. SECURITY DEPOSIT Concurrently with Tenant's execution of this Lease, Tenant shall deposit with Landlord a security deposit (the "Security Deposit") in the amount set forth in Section 8 of the Summary, as security for the faithful performance by Tenant of all of its obligations under this Lease. If Tenant defaults, beyond applicable notice and cure periods, with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, the removal of property and the repair of resultant damage, Landlord may, without notice to Tenant, but shall not be required to apply all or any part of the Security Deposit for the payment of any Rent or any other sum in default and Tenant shall, upon demand therefor, restore the Security Deposit to its original amount. Any unapplied portion of the Security Deposit shall be returned to Tenant, or, at Landlord's option, to the last assignee of Tenant's interest hereunder, within thirty (30) days following the expiration of the Lease Term. Tenant shall not be entitled to any interest on the Security Deposit. Tenant hereby irrevocably waives and relinquishes any and all rights, benefits, or protections, if any, Tenant now has, or in the future may have, under Section 1950.7 of the California Civil Code, any successor statue, and all other provisions of law, now or hereafter in effect, including, but not limited to, any provision of law which (i) establishes the time frame by which a landlord must refund a security deposit under a lease, or (ii) provides that a landlord may claim from a security deposit only those sums reasonably necessary to remedy defaults in the payment of rent, to repair damage caused by a tenant, or to clean the subject premises. Tenant acknowledges and agrees that (A) any statutory time frames for the return of a security deposit are superseded by the express period identified in this Article 21, above, and (B) rather than be so limited, Landlord may claim from the Security Deposit (x) any and all sums expressly identified in this Article 21, above, and (y) any additional sums reasonably necessary to compensate Landlord for any and all losses or damages caused by Tenant's default of this Lease, including, but not limited to, all damages or rent due upon termination of this Lease pursuant to Section 1951.2 of the California Civil Code.

22. COMMUNICATIONS AND COMPUTER LINE Tenant may install, maintain, replace, remove or use any communications or computer wires and cables serving the Premises (collectively, the "Lines"), provided that Tenant shall obtain Landlord's prior written consent, use an experienced and qualified contractor approved in writing by Landlord, and comply with all of the other provisions of Articles 7 and 8 of this Lease. Tenant shall pay all costs in connection therewith. Landlord reserves the right, upon notice to Tenant prior to the expiration or earlier termination of this Lease, to require that Tenant, at Tenant's sole cost and expense, remove any Lines located in or serving the Premises prior to the expiration or earlier termination of this Lease. Landlord shall, on or before the Lease Commencement Date, remove any existing wiring or cabling within the Premises that Tenant requests.

23.

SIGNS

23.1 Exterior Signage. Subject to Landlord's prior written approval, which shall not be unreasonably withheld, conditioned or delayed, and provided all signs are in keeping with the quality, design and style of the Building and Project, (i) Landlord, at its sole cost and expense, shall install identification signage for Tenant at the entrance to the Building, (ii) Landlord will, at Tenant's sole cost and expense, move Tenant's existing monument sign to a mutually agreed upon location at the Building, and (iii) Tenant may, at Tenant's sole cost, install signage identifying Tenant on the entrance door to the Premises (all such signage collectively, "Tenant Signage"); provided, however, in no event shall Tenant's Signage include an "Objectionable Name," as that term is defined in Section 23.2, of this Lease. All such signage shall be subject to Tenant's obtaining all required governmental approvals. All permitted signs shall be maintained by Tenant at its expense in a first-class and safe condition and appearance. Upon the expiration or earlier termination of this Lease, Tenant shall remove all of its signs at Tenant's sole cost and expense. The graphics, materials, color, design, lettering, lighting, size, illumination, specifications and exact location of Tenant's Signage (collectively, the "Sign Specifications") shall be subject to the prior written approval of Landlord, which approval shall not be unreasonably withheld, conditioned or delayed, and shall be consistent and compatible with the quality and nature of the Project. Tenant hereby acknowledges that, notwithstanding Landlord's approval of Tenant's Signage, Landlord has made no representation or warranty to Tenant with respect to the probability of obtaining all necessary governmental approvals and permits for Tenant's Signage. In the event Tenant does not receive the necessary governmental approvals and permits for Tenant's Signage, Tenant's and Landlord's rights and obligations under the remaining TCCs of this Lease shall be unaffected.

- 35 -

23.2 Objectionable Name. Tenant's Signage shall not include a name or logo which relates to an entity which is of a character or reputation, or is associated with a political faction or orientation, which is inconsistent with the quality of the Project, or which would otherwise reasonably offend a landlord of the Comparable Buildings (an "Objectionable Name"). The parties hereby agree that the following name, or any reasonable derivation thereof, shall be deemed not to constitute an Objectionable Name: "Compugen USA, Inc.".

23.3 Prohibited Signage and Other Items. Any signs, notices, logos, pictures, names or advertisements which are installed and that have not been separately approved by Landlord may be removed without notice by Landlord at the sole expense of Tenant. Any signs, window coverings, or blinds (even if the same are located behind the Landlord-approved window coverings for the Building), or other items visible from the exterior of the Premises or Building, shall be subject to the prior approval of Landlord, in its sole discretion.

23.4 Termination of Right to Tenant's Signage. The rights contained in this Article 23 shall be personal to Original Tenant and its Permitted Assignee, and may only be exercised and maintained by such parties (and not any other assignee, sublessee or other transferee of the Original Tenant's interest in this Lease) to the extent (x) they are not in default under this Lease (beyond any applicable notice and cure period) and (y) they occupy more than fifty percent (50%) of the Premises.

24. COMPLIANCE WITH LAW Tenant shall not do anything or suffer anything to be done in or about the Premises or the Project which will in any way conflict with any law, statute, ordinance or other governmental rule, regulation or requirement now in force or which may hereafter be enacted or promulgated including Environmental Laws (collectively, "Applicable Laws"). Tenant shall, at its sole cost and expense, promptly comply with any Applicable Laws which relate to (i) Tenant's use of the Premises, but Tenant shall be required to perform alterations to the Premises, Building, or Project to comply with laws only where such compliance requirement is triggered by Tenant’s particular use of the Premises (as opposed to general and customary office, lab or research and development use), (ii) any Alterations made by Tenant to the Premises, and any tenant improvements in the Premises. Should any standard or regulation now or hereafter be imposed on Landlord or Tenant by a state, federal or local governmental body charged with the establishment, regulation and enforcement of occupational, health or safety standards for employers, employees, landlords or tenants, then Tenant agrees, at its sole cost and expense, to comply promptly with such standards or regulations. Tenant shall be responsible, at its sole cost and expense, to make all alterations to the Building and Premises as are required to comply with the governmental rules, regulations, requirements or standards described in this Article 24, but Tenant shall be required to perform alterations to the Premises, Building, or Project to comply with laws only where such compliance requirement is triggered by Tenant’s particular use of the Premises (as opposed to general and customary office, lab or research and development use). Tenant shall not be responsible for remedying pre-existing violations of Applicable Laws with respect to the Premises, Building, or Project. The judgment of any court of competent jurisdiction or the admission of Tenant in any judicial action, regardless of whether Landlord is a party thereto, that Tenant has violated any of said governmental measures, shall be conclusive of that fact as between Landlord and Tenant. Landlord shall comply with all Applicable Laws relating to the Base Building, provided that compliance with such Applicable Laws is not the responsibility of Tenant under this Lease.

25. LATE CHARGES If any installment of Rent or any other sum due from Tenant shall not be received by Landlord or Landlord's designee within five (5) business days after Tenant's receipt of written notice from Landlord that said amount is due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any reasonable attorneys' fees incurred by Landlord by reason of Tenant's failure to pay Rent and/or other charges when due hereunder. The late charge shall be deemed Additional Rent and the right to require it shall be in addition to all of Landlord's other rights and remedies hereunder or at law and shall not be construed as liquidated damages or as limiting Landlord's remedies in any manner. In addition to the late charge described above, any Rent or other amounts owing hereunder which are not paid within ten (10) days after the date they are due shall bear interest from the date when due until paid at a rate per annum equal to the lesser of (i) the annual "Bank Prime Loan" rate cited in the Federal Reserve Statistical Release Publication G.13(415), published on the first Tuesday of each calendar month (or such other comparable index as Landlord and Tenant shall reasonably agree upon if such rate ceases to be published) plus four (4) percentage points, and (ii) the highest rate permitted by applicable law.

26.	LANDLORD'S RIGHT TO CURE DEFAULT; PAYMENTS BY TENANT

26.1 Landlord's Cure. All covenants and agreements to be kept or performed by Tenant under this Lease shall be performed by Tenant at Tenant's sole cost and expense and without any reduction of Rent, except to the extent, if any, otherwise expressly provided herein. If Tenant shall fail to perform any obligation under this Lease, and such failure shall continue in excess of the time allowed under Section 19.1.2, above, unless a specific time period is otherwise stated in this Lease, Landlord may, but shall not be obligated to, make any such payment or perform any such act on Tenant's part without waiving its rights based upon any default of Tenant and without releasing Tenant from any obligations hereunder.

26.2 Tenant's Reimbursement. Except as may be specifically provided to the contrary in this Lease, Tenant shall pay to Landlord, upon delivery by Landlord to Tenant of statements therefor: (i) sums equal to expenditures reasonably made and obligations incurred by Landlord in connection with the remedying by Landlord of Tenant's defaults pursuant to the provisions of Section 26.1; (ii) sums equal to all losses, costs, liabilities, damages and expenses referred to in Section 10.1 of this Lease; and (iii) sums equal to all expenditures made and obligations incurred by Landlord in collecting or attempting to collect the Rent or in enforcing or attempting to enforce any rights of Landlord under this Lease or pursuant to law, including, without limitation, all reasonable legal fees and other amounts so expended. Tenant's obligations under this Section 26.2 shall survive the expiration or sooner termination of the Lease Term.

27. ENTRY BY LANDLORD Landlord reserves the right at all reasonable times and upon reasonable prior notice to Tenant (which shall be at least 24 hours except in the case of an emergency) to enter the Premises (and Tenant shall have the right to accompany any such entry) to (i) inspect them; (ii) show the Premises to prospective purchasers, or to current or prospective mortgagees, ground or underlying lessors or insurers or, during the last twelve (12) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility (to the extent applicable pursuant to then applicable law); or (iv) alter, improve or repair the Premises or the Building, or for structural alterations, repairs or improvements to the Building or the Building's systems and equipment. Landlord may make any such entries without the abatement of Rent, except as otherwise provided in this Lease, and may take such reasonable steps as required to accomplish the stated purposes. In an emergency, Landlord shall have the right to use any means that Landlord may deem proper to open the doors in and to the Premises. Any entry into the Premises by Landlord in the manner hereinbefore described shall not be deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an actual or constructive eviction of Tenant from any portion of the Premises. Tenant shall have the right to designate certain areas of the Premises as "Secured Areas" (not to exceed 1,500 square feet of space) should Tenant require such areas for the purpose of securing certain valuable property or confidential information. Landlord shall not enter any Secured Areas except in the event of an emergency, or otherwise in connection with a specific request by Tenant. In connection with any such entry, Landlord will comply with Tenant’s reasonable safety and security requirements. Any such entries shall be performed by Landlord as expeditiously as reasonably possible and in a manner so as to minimize any interference with the conduct of Tenant’s business.

28. TENANT PARKING Tenant shall have the right to use the amount of parking set forth in Section 9 of the Summary, in the on-site and/or off-site, as the case may be, parking facility (or facilities) which serve the Project, at no additional charge during the initial Lease Term or any Option Term. Tenant shall abide by all reasonable rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility where the parking passes are located (including any sticker or other identification system established by Landlord and the prohibition of vehicle repair and maintenance activities in the parking facilities), and shall cooperate in seeing that Tenant's employees and visitors also comply with such rules and regulations. Tenant's use of the Project parking facility shall be at Tenant's sole risk and Tenant acknowledges and agrees that Landlord shall have no liability whatsoever for damage to the vehicles of Tenant, its employees and/or visitors, or for other personal injury or property damage or theft relating to or connected with the parking rights granted herein or any of Tenant's, its employees' and/or visitors' use of the parking facilities.

29.4 Modification of Lease. Should any current or prospective mortgagee or ground lessor for the Building or Project require a modification of this Lease, which modification will not cause an increased cost or expense to Tenant or in any other way materially and adversely change the rights and obligations of Tenant hereunder, then and in such event, Tenant agrees that this Lease may be so modified and agrees to execute whatever documents are reasonably required therefor and to deliver the same to Landlord within ten (10) business days following a request therefor. At the request of Landlord or any mortgagee or ground lessor, Tenant agrees to execute a short form of Lease and deliver the same to Landlord within ten (10) business days following the request therefor.

29.12 No Warranty. In executing and delivering this Lease, Tenant has not relied on any representations, including, but not limited to, any representation as to the amount of any item comprising Additional Rent or the amount of the Additional Rent in the aggregate or that Landlord is furnishing the same services to other tenants, at all, on the same level or on the same basis, or any warranty or any statement of Landlord which is not set forth herein or in one or more of the exhibits attached hereto.

29.13 Landlord Exculpation. The liability of Landlord or the Landlord Parties to Tenant for any default by Landlord under this Lease or arising in connection herewith or with Landlord's operation, management, leasing, repair, renovation, alteration or any other matter relating to the Project or the Premises shall be limited solely and exclusively to an amount which is equal to the lesser of (a) the interest of Landlord in the Building or (b) the equity interest Landlord would have in the Building if the Building were encumbered by third-party debt in an amount equal to eighty percent (80%) of the value of the Project. Neither Landlord, nor any of the Landlord Parties shall have any personal liability therefor, and Tenant hereby expressly waives and releases such personal liability on behalf of itself and all persons claiming by, through or under Tenant. The limitations of liability contained in this Section 29.13 shall inure to the benefit of Landlord's and the Landlord Parties' present and future partners, beneficiaries, officers, directors, trustees, shareholders, agents and employees, and their respective partners, heirs, successors and assigns. Under no circumstances shall any present or future partner of Landlord (if Landlord is a partnership), or trustee or beneficiary (if Landlord or any partner of Landlord is a trust), have any liability for the performance of Landlord's obligations under this Lease. Notwithstanding any contrary provision herein, neither Landlord nor the Landlord Parties shall be liable under any circumstances for injury or damage to, or interference with, Tenant's business, including but not limited to, loss of profits, loss of rents or other revenues, loss of business opportunity, loss of goodwill or loss of use, in each case, however occurring, or loss to inventory, scientific research, scientific experiments, laboratory animals, products, specimens, samples, and/or scientific, business, accounting and other records of every kind and description kept at the premises and any and all income derived or derivable therefrom.

29.14 Entire Agreement. It is understood and acknowledged that there are no oral agreements between the parties hereto affecting this Lease and this Lease constitutes the parties' entire agreement with respect to the leasing of the Premises and supersedes and cancels any and all previous negotiations, arrangements, brochures, agreements and understandings, if any, between the parties hereto or displayed by Landlord to Tenant with respect to the subject matter thereof, and none thereof shall be used to interpret or construe this Lease. None of the terms, covenants, conditions or provisions of this Lease can be modified, deleted or added to except in writing signed by the parties hereto.

29.15 Right to Lease. Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise of its sole business judgment shall determine to best promote the interests of the Building or Project. Tenant does not rely on the fact, nor does Landlord represent, that any specific tenant or type or number of tenants shall, during the Lease Term, occupy any space in the Building or Project.

29.16 Force Majeure. Any prevention, delay or stoppage due to strikes, lockouts, labor disputes, acts of God, acts of war, terrorist acts, inability to obtain services, labor, or materials or reasonable substitutes therefor, despite commercially reasonable efforts to procure the same, governmental actions, civil commotions, fire or other casualty, and other causes beyond the reasonable control of the party obligated to perform, except with respect to the obligations imposed with regard to Rent and other charges to be paid by Tenant pursuant to this Lease (collectively, a "Force Majeure"), notwithstanding anything to the contrary contained in this Lease, shall excuse the performance of such party for a period equal to any such prevention, delay or stoppage and, therefore, if this Lease specifies a time period for performance of an obligation of either party, that time period shall be extended by the period of any delay in such party's performance caused by a Force Majeure.

In such event, Tenant shall, within ten (10) days after execution of this Lease, deliver to Landlord satisfactory evidence of such authority and, if a corporation, upon demand by Landlord, also deliver to Landlord satisfactory evidence of (i) good standing in Tenant's state of incorporation and (ii) qualification to do business in the State of California.

HOWEVER, NOTHING HEREIN SHALL PROHIBIT TENANT FROM ASSERTING ANY DEFENSES IN ANY SUCH PROCEEDING.

(m) Capitalized terms not otherwise defined in this Tenant Work Letter shall have the definitions set forth in the Lease.

2. Plans and Construction. Landlord and Tenant shall comply with the procedures set forth in this Paragraph 2 in preparing, delivering and approving matters relating to the Tenant Improvements.

(a) Approved Plans and Working Drawings for Landlord's TI Work. Landlord's Architect and project manager has prepared, and Landlord and Tenant have approved, preliminary plans and specifications and a scope of work for the Premises. The most recent mutually approved version of such preliminary plans and specifications and scope of work (the "Landlord's Preliminary Plan") is attached hereto as Schedule 1 and incorporated herein by this reference. Any items listed on the Landlord's Preliminary Plan as being "alternates" or "tenant items", or "tenant furnished" or "tenant installed" shall be provided, if at all, by Tenant at Tenant's sole cost and expense, and Landlord shall have no obligations with respect thereto. Landlord shall prepare or cause to be prepared (assuming timely delivery by Tenant of all information and decisions reasonably required to be furnished or made by Tenant in order to permit preparation of Landlord's Final Working Drawings, and subject to Tenant Delays and Unavoidable Delays), final detailed working drawings and specifications for the Tenant Improvements constituting Landlord's TI Work, including (as applicable) structural, fire protection, life safety, mechanical and electrical working drawings and final architectural drawings (collectively, "Landlord's Final Working Drawings"). Landlord's Final Working Drawings shall be based on and consistent with the Landlord's Preliminary Plan in all material respects (except as otherwise mutually approved by the parties in their respective discretion). Landlord shall deliver copies of Landlord's Final Working Drawings to Tenant for Tenant's approval and information, and to assist Tenant in preparing plans, specifications and drawings for Tenant's Work as hereinafter set forth. Tenant shall promptly and diligently either approve the proposed Landlord's Final Working Drawings, or set forth in writing with particularity any changes necessary to bring the aspects of such proposed plans and specifications or proposed Landlord's Final Working Drawings into a form which will be reasonably acceptable to Tenant. Notwithstanding any other provisions of this paragraph, in no event shall Tenant have the right to object to any aspect of the Landlord's Final Working Drawings (including, but not limited to, any subsequently proposed changes therein from time to time) that is (i) materially consistent with the Landlord's Preliminary Plan, (ii) necessitated by applicable law or as a condition of any governmental or other third-party approvals or consents that are required to be obtained in connection with Landlord's TI Work, or (iii) that is required as a result of unanticipated conditions encountered in the course of construction of Landlord's TI Work, but to the extent Tenant identifies to Landlord any concerns arising out of any such requirements or conditions described in this sentence, Landlord and Tenant shall cooperate reasonably, diligently and in good faith to discuss possible changes in the nature or scope of the Tenant Improvements that might minimize or avoid the effects of such requirements or conditions. Failure of Tenant to deliver to Landlord written notice of disapproval and specification of required changes on or before any deadline reasonably specified by Landlord (which shall not be less than three (3) business days after delivery thereof to Tenant) in delivering an applicable set of plans, specifications and/or drawings to Tenant shall constitute and be deemed to be approval of Landlord's proposed plans and specifications or proposed Landlord's Final Working Drawings, as applicable.

EXHIBIT B

- 2 -

(b) Construction of Landlord's TI Work. Following completion of Landlord's Final Working Drawings, Landlord shall apply for and use reasonable efforts to obtain the necessary permits and approvals to allow construction of all Tenant Improvements constituting Landlord's TI Work. Upon receipt of such permits and approvals, Landlord shall, at Landlord's expense (subject to Tenant's obligations to pay for the cost of any Tenant required changes to the Landlord's Preliminary Plan or Landlord's Final Working Drawings), construct and complete the Tenant Improvements constituting Landlord's TI Work substantially in accordance with the Landlord's Approved Plans, subject to Unavoidable Delays and Tenant Delays (if any). Such construction shall be performed in a neat, good and workmanlike manner and shall materially conform to all applicable laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto in force at the time such work is completed.

(i) If Landlord determines at any time that changes in Landlord's Final Working Drawings or in any other aspect of the Landlord's Approved Plans relating to any item of Landlord's TI Work are required as a result of applicable law or governmental requirements,, or are required at the insistence of any other third party whose approval may be required with respect to the Tenant Improvements, or are required as a result of unanticipated conditions encountered in the course of construction, then Landlord shall promptly (A) advise Tenant of such circumstances and (B) at Landlord's sole cost and expense, cause revised Landlord's Final Working Drawings to be prepared by Landlord's Architect and submitted to Tenant, for Tenant's information, but to the extent Tenant identifies to Landlord any concerns arising out of any such changes, Landlord and Tenant shall cooperate reasonably, diligently and in good faith to make changes in the nature or scope of the Tenant Improvements that might minimize or avoid the effects of such changes.

(ii) If Tenant at any time desires any changes, alterations or additions to the Landlord's Final Working Drawings or material changes to the Landlord's Preliminary Plan with respect to any of Landlord's TI Work, Tenant shall submit a detailed written request to Landlord specifying such changes, alterations or additions (a "Tenant Change Request"). Upon receipt of any such request, Landlord shall promptly notify Tenant of (A) whether the matters proposed in the Tenant Change Request are approved by Landlord (which approval shall not be unreasonably withheld, conditioned or delayed by Landlord), (B) Landlord's estimate of the number of days of delay, if any, which shall be caused in Landlord's TI Work by such Tenant Change Request if implemented (including, without limitation, delays due to the need to obtain any revised plans or drawings and any governmental approvals), and (C) Landlord's estimate of the increase, if any, which shall occur in the cost of construction of the Landlord's TI Work affected by such Tenant Change Request if such Tenant Change Request is implemented (including, but not limited to, any costs of compliance with laws or governmental regulations that become applicable because of the implementation of the Tenant Change Request). If Landlord approves the Tenant Change Request and Tenant notifies Landlord in writing, within three (3) business days after receipt of such notice from Landlord, of Tenant's approval of the Tenant Change Request (including the estimated delays and cost increases, if any, described in Landlord's notice), then Landlord shall cause such Tenant Change Request to be implemented and Tenant shall be responsible for all actual costs or cost increases resulting from or attributable to the implementation of the Tenant Change Request, and any delays resulting therefrom shall be deemed to be a Tenant Delay. If Tenant fails to notify Landlord in writing of Tenant's approval of such Tenant Change Request within said three (3) business day period, then such Tenant Change Request shall be deemed to be withdrawn and shall be of no further effect.

(d) Project Management. Unless and until revoked by Landlord by written notice delivered to Tenant, Landlord hereby (i) delegates to Project Manager the authority to exercise all approval rights, supervisory rights and other rights or powers of Landlord under this Tenant Work Letter with respect to the design and construction of the Tenant Improvements, and (ii) requests that Tenant work with Project Manager with respect to any logistical or other coordination matters arising in the course of construction of the Tenant Improvements, including monitoring Tenant's compliance with its obligations under this Tenant Work Letter and under the Lease with respect to the design and construction of the Tenant Improvements. Tenant acknowledges the foregoing delegation and request, and agrees to cooperate reasonably with Project Manager as Landlord's representative pursuant to such delegation and request. Fees and charges of Project Manager for such services shall be at Landlord's sole expense except to the extent otherwise expressly provided in this Tenant Work Letter. Landlord will cause the Project Manager to provide a contact person who shall be the point of contact for Tenant and who shall be responsible for keeping Tenant apprised of the progress of the Tenant Improvements and, if requested by Tenant, who will meet with Tenant on a regular basis (not more often than weekly) to discuss the progress of the Tenant Improvements.

3. Completion.

(a) When Landlord receives written certification from Architect that construction of the Tenant Improvements constituting Landlord's TI Work in the Building has been completed in accordance with the Landlord's Approved Plans (except for Punch List Work), Landlord shall prepare and deliver to Tenant a certificate signed by both Landlord and Architect (the "Substantial Completion Certificate") (i) certifying that the construction of the Tenant Improvements constituting Landlord's TI Work in the Building has been substantially completed in a good and workmanlike manner in accordance with the Landlord's Approved Plans in all material respects, subject only to completion of Punch List Work, and specifying the date of that completion, and (ii) certifying that Landlord's TI Work complies in all material respects with all laws, rules, regulations, codes, ordinances, requirements, covenants, conditions and restrictions applicable thereto at the time of such delivery. Upon receipt by Tenant of the Substantial Completion Certificate and tender of possession of the Premises by Landlord to Tenant, and receipt of any certificate of occupancy or its legal equivalent, or other required sign-offs from any applicable governmental authority, allowing the legal occupancy of the Premises, the Tenant Improvements constituting Landlord's TI Work in the Building will be deemed delivered to Tenant and "Ready for Occupancy" for all purposes of the Lease (subject to Landlord's continuing obligations with respect to any Punch List Work, and to any other express obligations of Landlord under the Lease or this Tenant Work Letter with respect to such Tenant Improvements).

(b) Promptly following delivery of the Substantial Completion Certificate for Landlord's TI Work in the Building, Project Manager or other representatives of Landlord shall conduct one or more "walkthroughs" of the Building with Tenant and Tenant's representatives, to identify any items of Punch List Work that may require correction and to prepare a joint punch list reflecting any such items, following which Landlord shall diligently complete the Punch List Work reflected in such joint punch list. At any time within thirty (30) days after delivery of such Substantial Completion Certificate, Tenant shall be entitled to submit one or more lists to Landlord supplementing such joint punch list by specifying any additional items of Punch List Work to be performed on the applicable Tenant Improvements constituting Landlord's TI Work in the Building, and upon receipt of such list(s), Landlord shall diligently complete such additional Punch List Work. Promptly after Landlord provides Tenant with the Substantial Completion Certificate and completes all applicable Punch List Work for the Building, Landlord shall cause the recordation of a Notice of Completion (as defined in Section 3093 of the California Civil Code or applicable successor statute) with respect to Landlord's TI Work in the Building.

(c) All construction, product and equipment warranties and guaranties obtained by Landlord with respect to Landlord's TI Work shall, to the extent reasonably obtainable, include a provision that such warranties and guaranties shall also run to the benefit of Tenant, and Landlord shall cooperate with Tenant in a commercially reasonable manner to assist in enforcing all such warranties and guaranties for the benefit of Tenant. In addition to the foregoing, Landlord will warrant that the Building Systems and Landlord's TI Work are free from defects for a period of one (1) year after the date the Premises are Ready for Occupancy. In the event of any breach of the foregoing warranty, as Tenant's sole remedy for such breach, Landlord will repair any such defects at no cost to Tenant.

(d) Notwithstanding any other provisions of this Tenant Work Letter or of the Lease, if Landlord is delayed in substantially completing any of Landlord's TI Work as a result of any Tenant Delay, then notwithstanding any other provisions of the Lease to the contrary, the Premises shall be deemed to have been Ready for Occupancy on the date the Premises would have been Ready for Occupancy absent such Tenant Delay.

(e) Landlord shall not require Tenant to remove any of the Tenant Improvements to the extent shown on Landlord's Preliminary Plan attached hereto as Schedule 1.

EXHIBIT B

- 4 -

4. Payment of Costs. Except as otherwise expressly provided in this Tenant Work Letter or in the Lease or by mutual written agreement of Landlord and Tenant, the cost of construction of the Tenant Improvements shall be paid by Landlord.

5. No Agency. Nothing contained in this Tenant Work Letter shall make or constitute Tenant as the agent of Landlord.

6. Tenant Access. Provided that Tenant and its agents do not interfere with Contractor's work in the Building and the Premises, Contractor shall allow Tenant access to the Premises for the purpose of Tenant installing equipment or fixtures (including Tenant's data and telephone equipment) in the Premises and doing business. Prior to Tenant's entry into the Premises as permitted by the terms of this Section 6, Tenant shall submit a schedule to Landlord and Contractor, for their approval, which schedule shall detail the timing and purpose of Tenant's entry. Tenant shall be responsible for the costs of any utilities associated with Tenant's access to the Premises prior to the Lease Commencement Date. Tenant shall hold Landlord harmless from and indemnify, protect and defend Landlord against any loss or damage to the Building or Premises and against injury to any persons caused by Tenant's actions pursuant to this Section 6.

7. Miscellaneous. All references in this Tenant Work Letter to a number of days shall be construed to refer to calendar days, unless otherwise specified herein. In all instances where Landlord's or Tenant's approval is required, if no written notice of disapproval is given within the applicable time period, at the end of that period Landlord or Tenant shall be deemed to have given approval (unless the provision requiring Landlord's or Tenant's approval expressly states that non-response is deemed to be a disapproval or withdrawal of the pending action or request, in which event such express statement shall be controlling over the general statement set forth in this sentence) and the next succeeding time period shall commence. If any item requiring approval is disapproved by Landlord or Tenant (as applicable) in a timely manner, the procedure for preparation of that item and approval shall be repeated.

FORM OF GUARANTY OF LEASE

THIS GUARANTY OF LEASE (this "Guaranty") is made as of November ___, 2013, by COMPUGEN, LTD. (the "Guarantor"), whose address is as set forth in Section 10 hereof, in favor of BRITANNIA POINTE GRAND LIMITED PARTNERSHIP, a Delaware limited partnership ("Landlord").

WHEREAS, Landlord and COMPUGEN USA, INC., a Delaware corporation ("Tenant") desire to enter into that certain Lease dated November ___, 2013 (the "Lease") concerning the premises on the ground floor, Suite 65, of the building located at 000 Xxxx Xxxxx, Xxxxx Xxx Xxxxxxxxx, Xxxxxxxxxx;

WHEREAS, Guarantor has a financial interest in the Tenant; and

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

NOW, THEREFORE, for and in consideration of the execution of the foregoing Lease by Landlord and as a material inducement to Landlord to execute said Lease, Guarantor hereby absolutely, presently, continually, unconditionally and irrevocably guarantees the prompt payment by Tenant of all rentals and other sums payable by Tenant under said Lease and the faithful and prompt performance by Tenant of each and every one of the terms, conditions and covenants of said Lease to be kept and performed by Tenant, and further agrees as follows:

1. It is specifically agreed and understood that the terms, covenants and conditions of the Lease may be altered, affected, modified, amended, compromised, released or otherwise changed by agreement between Landlord and Tenant, or by course of conduct and Guarantor does guaranty and promise to perform all of the obligations of Tenant under the Lease as so altered, affected, modified, amended, compromised, released or changed and the Lease may be assigned by or with the consent of Landlord or any assignee of Landlord without consent or notice to Guarantor and that this Guaranty shall thereupon and thereafter guaranty the performance of said Lease as so changed, modified, amended, compromised, released, altered or assigned; provided, however, if notice and consent of Guarantor is not sought, Guarantor shall not be responsible for increased obligations with respect to the Lease as so modified, renewed, extended, amended or otherwise affected.

2. This Guaranty shall not be released, modified or affected by failure or delay on the part of Landlord to enforce any of the rights or remedies of Landlord under the Lease, whether pursuant to the terms thereof or at law or in equity, or by any release of any person liable under the terms of the Lease (including, without limitation, Tenant) or any other guarantor, including without limitation, any other Guarantor named herein, from any liability with respect to Guarantor's obligations hereunder.

3. Guarantor's liability under this Guaranty shall continue until all rents due under the Lease have been paid in full in cash and until all other obligations to Landlord have been satisfied, and shall not be reduced by virtue of any payment by Tenant of any amount due under the Lease. If all or any portion of Tenant's obligations under the Lease is paid or performed by Tenant, the obligations of Guarantor hereunder shall continue and remain in full force and effect in the event that all or any part of such payment(s) or performance(s) is avoided or recovered directly or indirectly from Landlord as a preference, fraudulent transfer or otherwise.

4. Guarantor warrants and represents to Landlord that Guarantor has reviewed and approved copies of the Lease and is fully informed of the remedies Landlord may pursue, with or without notice to Tenant, in the event of default under the Lease. So long as any of the Guarantor's obligations hereunder remains unsatisfied or owing to Landlord, Guarantor shall keep fully informed as to all aspects of Tenant's financial condition and the performance of said obligations.

EXHIBIT F

- 1 -

5. Guarantor hereby covenants and agrees with Landlord that if a default shall at any time occur in the payment of any sums due under the Lease by Tenant or in the performance of any other obligation of Tenant under the Lease, Guarantor shall and will forthwith upon demand pay such sums and any arrears thereof, to Landlord in legal currency of the United States of America for payment of public and private debts, and take all other actions necessary to cure such default and perform such obligations of Tenant.

6. The liability of Guarantor under this Guaranty is a guaranty of payment and performance with respect to any monetary and non-monetary obligations of Tenant under the Lease upon an event of default by Tenant with respect to such obligations.

7. Guarantor hereby waives and agrees not to assert or take advantage of to the extent permitted by law: (i) all notices to Guarantor, to Tenant, or to any other person, including, but not limited to, notices of the acceptance of this Guaranty or the creation, renewal, extension, assignment, modification or accrual of any of the obligations owed to Landlord under the Lease and, except to the extent set forth in Section 9 hereof, enforcement of any right or remedy with respect thereto, and notice of any other matters relating thereto; (ii) notice of acceptance of this Guaranty; (iii) demand of payment, presentation and protest; (iv) any right to require Landlord to apply to any default any security deposit or other security it may hold under the Lease; (v) intentionally omitted; (vi) any right or defense that may arise by reason of the incapability, lack of authority, death or disability of Tenant or any other person; (vii) all principles or provisions of law which conflict with the terms of this Guaranty, and (viii) any other rights and defenses that are or may become available to Guarantor by reason of Sections 2787 through 2855, inclusive, of the California Civil Code. Guarantor further agrees that Landlord may enforce this Guaranty upon the occurrence of a default under the Lease, notwithstanding any dispute between Landlord and Tenant with respect to the existence of said default or performance of the obligations under the Lease or any counterclaim, set-off or other claim which Tenant may allege against Landlord with respect thereto; provided that (a) Guarantor may assert the defense of Tenant's payment and performance under the Lease as a defense hereunder, and (b) Landlord's default under the Lease shall excuse Guarantor's performance to the same extent it would excuse Tenant's performance under the Lease. Moreover, Guarantor agrees that Guarantor's obligations shall not be affected by any circumstances which constitute a legal or equitable discharge of a guarantor or surety.

8. Guarantor agrees that Landlord may enforce this Guaranty without the necessity of proceeding against Tenant or any other guarantor. Guarantor hereby waives the right to require Landlord to proceed against Tenant, to proceed against any other guarantor, to exercise any right or remedy under the Lease or to pursue any other remedy or to enforce any other right.

9. (a) Guarantor agrees that nothing contained herein shall prevent Landlord from suing on the Lease or from exercising any rights available to it thereunder and that the exercise of any of the aforesaid rights shall not constitute a legal or equitable discharge of Guarantor. Without limiting the generality of the foregoing, Guarantor hereby expressly waives any and all benefits under California Civil Code § § 2809, 2810, 2815, 2819, 2821, 2822, 2824, 2839, 2845, 2847, 2848, 2849, 2850, 2855, 2899 and 3433.

(b) Guarantor agrees that Guarantor shall have no right of subrogation against Tenant or any right of contribution against any other guarantor unless and until all amounts due under the Lease have been paid in full and all other obligations under the Lease have been satisfied. Guarantor further agrees that, to the extent the waiver of Guarantor's rights of subrogation and contribution as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any rights of subrogation Guarantor may have against Tenant shall be junior and subordinate to any rights Landlord may have against Tenant, and any rights of contribution Guarantor may have against any other guarantor shall be junior and subordinate to any rights Landlord may have against such other guarantor.

(c) The obligations of Guarantor under this Guaranty shall not be altered, limited or affected by any case, voluntary or involuntary, involving the bankruptcy, insolvency, receivership, reorganization, liquidation or arrangement of Tenant or any defense which Tenant may have by reason of order, decree or decision of any court or administrative body resulting from any such case. Landlord shall have the sole right to accept or reject any plan on behalf of Guarantor proposed in such case and to take any other action which Guarantor would be entitled to take, including, without limitation, the decision to file or not file a claim. Guarantor acknowledges and agrees that any payment which accrues with respect to Tenant's obligations under the Lease (including, without limitation, the payment of rent) after the commencement of any such proceeding (or, if any such payment ceases to accrue by operation of law by reason of the commencement of such proceeding, such payment as would have accrued if said proceedings had not been commenced) shall be included in Guarantor's obligations hereunder because it is the intention of the parties that said obligations should be determined without regard to any rule or law or order which may relieve Tenant of any of its obligations under the Lease. Guarantor hereby permits any trustee in bankruptcy, receiver, debtor-in-possession, assignee for the benefit of creditors or similar person to pay Landlord, or allow the claim of Landlord in respect of, any such payment accruing after the date on which such proceeding is commenced. Guarantor hereby assigns to Landlord Guarantor's right to receive any payments from any trustee in bankruptcy, receiver, debtor-in-possession, assignee for the benefit of creditors or similar person by way of dividend, adequate protection payment or otherwise.

This Guaranty has been duly executed and delivered by Guarantor, and constitutes the legally valid and binding obligation of Guarantor enforceable against such Guarantor in accordance with its terms.

(b) The execution, delivery and performance of this Guaranty will not violate any provision of any existing law or regulation binding on Guarantor, or any order, judgment, award or decree of any court, arbitrator or governmental authority binding on Guarantor, or of any mortgage, indenture, lease, contract or other agreement, instrument or undertaking to which Guarantor is a party or by which Guarantor or any of Guarantor's assets may be bound, and will not result in, or require, the creation or imposition of any lien on any of Guarantor's property, assets or revenues pursuant to the provisions of any such mortgage, indenture, lease, contract, or other agreement, instrument or undertaking.

12. The obligations of Tenant under the Lease to execute and deliver estoppel statements, as therein provided, shall be deemed to also require the Guarantor hereunder to do and provide the same relative to Guarantor.

13. This Guaranty shall be binding upon Guarantor, Guarantor's heirs, representatives, administrators, executors, successors and assigns and shall inure to the benefit of and shall be enforceable by Landlord, its successors, endorsees and assigns. Any married person executing this Guaranty agrees that recourse may be had against community assets and against his separate property for the satisfaction of all obligations herein guaranteed. As used herein, the singular shall include the plural, and the masculine shall include the feminine and neuter and vice versa, if the context so requires.

14. The term "Landlord" whenever used herein refers to and means the Landlord specifically named in the Lease and also any assignee of said Landlord, whether by outright assignment or by assignment for security, and also any successor to the interest of said Landlord or of any assignee in the Lease or any part thereof, whether by assignment or otherwise.

15. The term "Tenant" whenever used herein refers to and means the Tenant in the Lease specifically named and also any assignee or sublessee of said Lease and also any successor to the interests of said Tenant, assignee or sublessee of such Lease or any part thereof, whether by assignment, sublease or otherwise.

16. Notwithstanding contrary provisions of this Guaranty, in the event that (i) Landlord consents to an assignment of the Lease by the Tenant or Tenant performs a Permitted Transfer in accordance with Section 14 of the Lease (either transfer, a “Permitted Transfer”), and (ii) at the time of the Permitted Transfer: (a) there is no Default; (b) Guarantor has faithfully performed and observed any and all guaranteed obligations which may have arisen prior to the effective date of the Permitted Transfer; and, (c) an entity or individual with a net worth (as demonstrated by audited financial statements prepared in accordance with generally accepted accounting principles) equal to or greater than the guarantor named above has agreed to assume the obligations of the Guarantor under this Guaranty that arise after the effective date of the Permitted Transfer, then the Guarantor named in this Guaranty shall be released from any continuing liability or obligation under this Guaranty that may arise after the effective date of the Permitted Transfer.
