PACIFIC CORPORATE CENTER

AMENDED AND RESTATED OFFICE LEASE

R E C I T A L S :

A.                                   This Amended and Restated Office Lease (“Office Lease”), which includes the preceding Summary of Basic Lease Information (the “Summary”) attached hereto and incorporated herein by this reference (the Office Lease and Summary are sometimes collectively referred to herein as the “Lease”), dated as of the date set forth in Section 1 of the Summary is made by and between ▇▇▇▇▇▇ REALTY, L.P., a Delaware limited partnership (“Landlord”), and FAVRILLE, INC., a Delaware corporation (“Tenant”).

B.                                     Landlord, and Tenant previously entered into that certain Office Lease dated January 31, 2004 (the “Original Office Lease”), as amended by that certain First Amendment to Lease dated July 2004 (the “First Amendment”), that certain Second Amendment to Lease dated October 11, 2004 (the “Second Amendment”), that certain Third Amendment to Lease dated July 8, 2005 (the “Third Amendment”), and that certain Fourth Amendment to Lease dated October 31, 2005 (the “Fourth Amendment”), whereby Landlord leased to Tenant and Tenant leased from Landlord the entire building located at ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ (the “10421 Building”) comprised (i) those certain premises (the “Original Premises”) consisting of 48,502 rentable square feet of space located on the first (1^st) and second (2^nd) floors of the Building, (ii) those certain premises (the “First Expansion Premises”) consisting of 13,987 rentable square feet of space located on the second (2^nd) floor of the Building, and (iii) those certain premises (the “Third Expansion Premises”) consisting of approximately 17,382 rentable square feet located on the first (1^st) floor of the Building (the Original Premises, the First Expansion Premises and the Third Expansion Premises are, collectively, (x) initially referred to herein as the “Premises,” and (x) alternatively, and throughout the Lease Term, referred to herein as the “10421 Premises”).  The Office Lease, the First Amendment, the Second Amendment, the Third Amendment and the Fourth Amendment are, collectively, the “Original Lease.”

C.                                     The Original Office Lease was initially entered into by Landlord and Tenant with respect to the Original Premises only, and because such Original Premises did not comprise the entire Building, the rights and obligations of both Landlord and Tenant under the terms of the Original Office Lease were structured so as to be a part of, and integrated with, a larger, multi-tenant building.  Following the execution of the Third Amendment and Tenant’s lease of the Third Expansion Premises, Landlord leases to Tenant and Tenant leases from Landlord the entire Building.  As a result thereof, the parties acknowledge and agree that certain of the terms and conditions relating directly to a multi-tenant building which are set forth in the Original Lease are no longer applicable.

D.                                    Landlord and Tenant desire to amend and restate the terms of the Original Lease in their entirety, effective as of the Effective Date, as set forth herein.

5

E.                                      Following the date of this Lease, Landlord and Tenant desire to expand the 10421 Premises to include the entire building (the “10445 Premises”) located at ▇▇▇▇▇ ▇▇▇▇▇▇▇ ▇▇▇▇▇▇ ▇▇▇▇▇, ▇▇▇ ▇▇▇▇▇, ▇▇▇▇▇▇▇▇▇▇ (the “10445 Building”).  However, as such 10445 Premises is currently occupied by a third party (“Nuera”) pursuant to an existing lease between Landlord and Nuera (the “Nuera Lease”), Landlord and Tenant acknowledge that such expansion, and Landlord’s ability to deliver the 10445 Building to Tenant, is expressly conditioned upon the termination or expiration of the Nuera Lease as set forth more particularly in Section 29.37 of this Lease.  In the event that the Nuera Lease is so terminated, or upon the expiration thereof, then Landlord and Tenant shall immediately thereafter enter into that certain First Amendment to Amended and Restated Office Lease (which shall amend this Lease) in the form attached hereto as Exhibit H (the “First Amendment to Amended and Restated Office Lease”).  All of the terms and conditions of this Lease, as amended by the terms of such First Amendment to Amended and Restated Office Lease, shall be effective immediately upon the full execution and delivery of such First Amendment to Amended and Restated Office Lease by and between Landlord and Tenant (the “10445 Premises Effective Date”).

F.                                      Upon the date set forth in Section 1.2 of the Summary (the “Effective Date”),  this Lease shall amend and restate the Original Lease in its entirety and shall thereafter supersede the Original Lease.  The provisions of the Original Lease shall remain in effect as to all periods prior to the Effective Date.

LEASE TERM; OPTION TERM(S)

2.1                                 Initial Lease Term.  The TCCs 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; provided, however, that the first Lease Year shall commence on the Lease Commencement Date and end on the last day of the eleventh month thereafter and the second and each succeeding Lease Year shall commence on the first day of the next calendar month; and further provided that the last Lease Year shall end on the Lease Expiration Date.  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) days of receipt thereof.

2.2                                 Option Term(s).

2.2.1                        Option Right.  Landlord hereby grants the Tenant originally named herein (the “Original Tenant”), its “Affiliates” (as that term is defined in Section 14.8, below) and any permitted assignee of the Original Tenant’s interest in this Lease pursuant to Article 14 of this Lease (a “Permitted Assignee”), two (2) options to extend the Lease Term for the entire 10421 Premises each by a period of five (5) years (each, an “Option Term”).  Such options shall be exercisable only by Notice delivered by Tenant to Landlord as provided below, provided that, as of the date of delivery of such Notice, Tenant is not in default under this Lease (beyond any applicable notice and cure periods).  Upon the proper exercise of an option to extend, and provided that, as of the end of the then applicable Lease term, Tenant is not in default under this Lease (beyond any applicable notice and cure periods), the Lease Term, as it applies to the entire 10421 Premises, shall be extended for a period of five (5) years.  The rights contained in this Section 2.2 shall only be exercised by the Original Tenant, its Affiliate or a Permitted Assignee (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if Original Tenant, its Affiliate and/or a Permitted Assignee is in possession of the entire then-existing 10421 Premises.  In the event the 10445 Premises is leased by Tenant, Tenant’s right to extend the Lease Term with respect to such 10445 Premises shall be as expressly set forth in the First Amendment to Amended and Restated Office Lease, and which right shall be independent of the right to extend the Lease Term with respect to the 10421 Premises as set forth in this Section 2.2. Accordingly, Tenant shall have the right to exercise the applicable option rights with respect to the 10421 Premises, the 10445 Premises, or both, in Tenant’s sole discretion.

2.2.2                        Option Rent.  The Rent payable by Tenant during the Option Term (the “Option Rent”) shall be equal to the Market Rent as set forth below.  For purposes of this Lease, the term “Market Rent” shall mean rent (including additional rent and considering any “base year” or “expense stop” applicable thereto), including all escalations, at which tenants, as of the

8

commencement of the applicable term are, pursuant to transactions completed within the twenty-four (24) months prior to the date Tenant delivers to Landlord the “Exercise Notice,” as that term is set forth below, leasing non-sublease, non-encumbered, non-synthetic, non-equity space (unless such space was leased pursuant to a definition of “fair market” comparable to the definition of Market Rent) comparable in size, location and quality to the Premises for a “Comparable Term,” as that term is defined in this Section 2.2.2 (the “Comparable Deals”), which comparable space is located in the “Comparable Buildings,” as that term is defined in this Section 2.2.2, giving appropriate consideration to the annual rental rates per rentable square foot (adjusting the base rent component of such rate to reflect a net value after accounting for whether or not utility expenses are directly paid by the tenant such as Tenant’s direct utility payments provided for in Section 6.1 of this Lease), the standard of measurement by which the rentable square footage is measured, parking ratios, general access to such Comparable Buildings, the general visibility of such Comparable Buildings, and taking into consideration only, and granting only, the following concessions (provided that the rent payable in Comparable Deals in which the terms of such Comparable Deals are determined by use of a discounted fair market rate formula shall be equitably increased in order that such Comparable Deals will not reflect a discounted rate) (collectively, the “Rent Concessions”):  (a) rental abatement concessions or build-out periods, if any, being granted such tenants in connection with such comparable spaces; (b) tenant improvements or allowances provided or to be provided for such comparable space, taking into account the value of the existing improvements in the Premises, such value to be based upon the age, quality and layout of the improvements and the extent to which the same can be utilized by this particular Tenant, (c) Proposition 13 protection, and (d) all other monetary concessions, if any, being granted such tenants in connection with such comparable space; provided, however, that notwithstanding anything to the contrary herein, no consideration shall be given to the fact that Landlord is or is not required to pay a real estate brokerage commission in connection with the applicable term or the fact that the Comparable Deals do or do not involve the payment of real estate brokerage commissions.  The term “Comparable Term” shall refer to the length of the lease term, without consideration of options to extend such term, for the space in question.  In addition, the determination of the Market Rent shall 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 during any Option Term.  Such determination shall be made by reviewing the extent of financial security then generally being imposed in Comparable Transactions upon 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).  If in determining the Market Rent, Tenant would, pursuant to the Comparable Deals and the Rent Concessions set forth therein, otherwise be entitled to a tenant improvement or comparable allowance for the improvement of the Premises (the “Option Term TI Allowance”), Tenant shall not be entitled, and shall not be compelled, to receive such Option Term TI Allowance and Landlord shall reduce the rental rate component of the Market Rent to be an effective rental rate which takes into consideration that Tenant will not receive any Option Term TI Allowance.  The term “Comparable Buildings” shall mean the Building and other first-class “cGMP/lab buildings” which are comparable to the Building in terms of age (based upon the date of completion of construction or major renovation as to the building containing the portion of the Premises in question), quality of construction, level of services and amenities, size

9

and appearance, and are located in the Sorrento Mesa, University Towne Center and ▇▇▇▇▇▇ ▇▇▇▇▇ area of San Diego, California (the “Comparable Area”).

2.2.3                        Exercise of Option.  The option contained in this Section 2.2 shall be exercised by Tenant, if at all, only in the manner set forth in this Section 2.2.3.  Tenant shall deliver notice (the “Exercise Notice”) to Landlord not more than fifteen (15) months nor less than nine (9) months prior to the expiration of the then Lease Term, stating that Tenant is exercising its option.  Concurrently with such Exercise Notice, Tenant shall deliver to Landlord Tenant’s calculation of the Market Rent (the “Tenant’s Option Rent Calculation”).  Landlord shall deliver notice (the “Landlord Response Notice”) to Tenant on or before the later to occur of (i) the date which is thirty (30) days after Landlord’s receipt of the Exercise Notice and Tenant’s Option Rent Calculation, and (ii) the date which is nine (9) months prior to the expiration of the then Lease Term (the “Landlord Response Date”), stating that (A) Landlord is accepting Tenant’s Option Rent Calculation as the Market Rent, or (B) rejecting Tenant’s Option Rent Calculation and setting forth Landlord’s calculation of the Market Rent (the “Landlord’s Option Rent Calculation”).  Within ten (10) business days of its receipt of the Landlord Response Notice, Tenant may, at its option, accept the Market Rent contained in the Landlord’s Option Rent Calculation.  If Tenant does not affirmatively accept or Tenant rejects the Market Rent specified in the Landlord’s Option Rent Calculation, the parties shall follow the procedure, and the Market Rent shall be determined as set forth in Section 2.2.5.

2.2.4                        No Defaults; Required Financial Condition of Tenant.  The rights contained in this Section 2.2 shall be personal to the Original Tenant, its Affiliates and any Permitted Assignee and may only be exercised by such Original Tenant, Affiliate or Permitted Assignee (and not any other assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if the Original Tenant, Affiliate and/or Permitted Assignee occupies not less than one hundred percent (100%) of the then existing Premises.  The right to extend the Lease Term as provided in this Section 2.2 may not be exercised if, as of the date of the attempted exercise of the extension option by Tenant, or as of the commencement date of such Option Term, (A) Tenant is in economic or material default pursuant to the terms of this Lease (beyond any applicable notice and cure periods), or (B) Tenant has previously been in economic or material default under this Lease (beyond any applicable notice and cure periods) during the previous twenty-four (24) month period.

2.2.5                        Determination of Market Rent.  In the event Tenant objects or is deemed to have objected to the Market Rent, Landlord and Tenant shall attempt to agree upon the Market Rent using reasonable good-faith efforts.  If Landlord and Tenant fail to reach agreement within sixty (60) days following Tenant’s objection or deemed objection to the Landlord’s Option Rent Calculation (the (the “Outside Agreement Date”), then (i) in connection with the Option Rent, Landlord’s Option Rent Calculation and Tenant’s Option Rent Calculation, each as previously delivered to the other party, shall be submitted to the arbitrators pursuant to the TCCs of this Section 2.2.4, and (ii) in connection with any other contested calculation of market Rent, the parties shall each make a separate determination of the Market Rent and shall submit the same to the arbitrators pursuant to the TCCs of this Section 2.2.5.  The submittals shall be made concurrently with the selection of the arbitrators pursuant to this Section 2.2.5 and shall be submitted to arbitration in accordance with Section 2.2.5.1 through 2.2.5.5 of this Lease, but subject to the conditions, when appropriate, of Section 2.2.3.

2.2.5.1               Landlord and Tenant shall mutually and reasonably select and appoint one arbitrator who shall by profession be a real estate broker, appraiser or attorney (the “Neutral Arbitrator”) who shall have been active over the five (5) year period ending on the date of such appointment in the leasing (or appraisal, as the case may be) of first-class office/lab/manufacturing properties in the Comparable Area.  The determination of the Neutral Arbitrator shall be limited solely to the issue of whether Landlord’s or Tenant’s submitted Market Rent, is the closest to the actual Market Rent as determined by the Neutral Arbitrator, taking into account the requirements of Section 2.2.2 of this Lease.  Such Neutral Arbitrator shall be appointed within thirty (30) days after the applicable Outside Agreement Date.  Neither the Landlord nor Tenant may, directly or indirectly, consult with the Neutral Arbitrator prior to 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.

2.2.4.2               Within thirty (30) days of the appointment of the Neutral Arbitrator, such Neutral Arbitrator shall reach a decision as to Market Rent and determine whether the Landlord’s or Tenant’s determination of Market Rent as submitted pursuant to Section 2.2.5.1 and Section 2.2.3 of this Lease is closest to Market Rent as determined by such Neutral Arbitrator and simultaneously publish a ruling (“Award”) indicating whether Landlord’s or Tenant’s submitted Market Rent is closest to the Market Rent as determined by the Neutral Arbitrator.  Following notification of the Award, the Landlord’s or Tenant’s submitted Market Rent determination, whichever is selected by the Neutral Arbitrator as being closest to Market rent shall become the then applicable Market Rent.

2.2.4.3               The Award issued by the Neutral Arbitrator shall be binding upon Landlord and Tenant.

2.2.4.4               If Landlord and Tenant fail to agree upon and appoint the Neutral Arbitrator, then either party may petition Judicial Arbitration & Mediation Services, Inc. (“JAMS”) to designate an independent third party to appoint the Neutral Arbitrator, subject to criteria in Section 2.2.5.1 of this Lease.

2.2.4.5               The cost of arbitration shall be paid by the party (either Landlord or Tenant) whose Market Rent is not selected by the Neutral Arbitrator.

4.2.5                        Taxes.

4.2.5.1               “Tax Expenses” shall mean all federal, state, county, or local governmental or municipal taxes, fees, charges or other impositions of every kind and nature, whether general, special, ordinary or extraordinary, (including, without limitation, real estate taxes, general and special assessments, transit taxes, leasehold taxes or taxes based upon the receipt of rent, including gross receipts or sales taxes applicable to the receipt of rent, unless required to be paid by Tenant, personal property taxes imposed upon the fixtures, machinery, equipment, apparatus, systems and equipment, appurtenances, furniture and other personal property used in connection with the Project, or any portion thereof), which shall be paid or accrued during any Expense Year (without regard to any different fiscal year used by such governmental or municipal authority) because of or in connection with the ownership, leasing

16

and operation of the Project, or any portion thereof.  Notwithstanding anything to the contrary set forth in this Section 4.2.5, Tax Expenses shall specifically exclude bonds and/or assessments which have been or, subsequent to the date hereof are, levied for the purpose of funding the costs of construction of all or any portion of the Project or capital improvements constructed therein or about, or on-or off-site improvements with respect thereto, to the extent such improvements are the sole responsibility of Landlord under the TCCs of this Lease.

4.2.5.2               Tax Expenses shall include, without limitation:  (i) Any tax on the rent, right to rent or other income from the Project, or any portion thereof, or as against the business of leasing the Project, or any portion thereof; (ii) Any assessment, tax, fee, levy or charge in addition to, or in substitution, partially or totally, of any assessment, tax, fee, levy or charge previously included within the definition of real property tax, it being acknowledged by Tenant and Landlord that Proposition 13 was adopted by the voters of the State of California in the June 1978 election (“Proposition 13”) and that assessments, taxes, fees, levies and charges may be imposed by governmental agencies for such services as fire protection, street, sidewalk and road maintenance, refuse removal and for other governmental services formerly provided without charge to property owners or occupants, and, in further recognition of the decrease in the level and quality of governmental services and amenities as a result of Proposition 13, Tax Expenses shall also include any governmental or private assessments or the Project’s contribution towards a governmental or private cost-sharing agreement for the purpose of augmenting or improving the quality of services and amenities normally provided by governmental agencies; (iii) Any assessment, tax, fee, levy, or charge allocable to or measured by the area of the Premises or the Rent payable hereunder, including, without limitation, any business or gross income tax or excise tax with respect to the receipt of such rent, or upon or with respect to the possession, leasing, operating, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises, or any portion thereof; and (iv) Any assessment, tax, fee, levy or charge, upon this transaction or any document to which Tenant is a party, creating or transferring an interest or an estate in the Premises.

4.2.5.3               Any costs and expenses (including, without limitation, reasonable attorneys’ fees) incurred in attempting to protest, reduce or minimize Tax Expenses shall be included in Tax Expenses in the Expense Year such expenses are paid.  Except as set forth in Section 4.2.5.4, below, refunds of Tax Expenses shall be credited against Tax Expenses and refunded to Tenant regardless of when received, based on the Expense Year to which the refund is applicable, provided that in no event shall the amount to be refunded to Tenant for any such Expense Year exceed the total amount paid by Tenant as Additional Rent under this Article 4 for such Expense Year.  If Tax Expenses for any period during the Lease Term or any extension thereof are increased after payment thereof for any reason, including, without limitation, error or reassessment by applicable governmental or municipal authorities, Tenant shall pay Landlord upon demand Tenant’s Share of any such increased Tax Expenses included by Landlord as Building Tax Expenses pursuant to the TCCs of this Lease.  Notwithstanding anything to the contrary contained in this Section 4.2.8 (except as set forth in Section 4.2.8.1, above), there shall be excluded from Tax Expenses (i) all excess profits taxes, franchise taxes, gift taxes, capital stock taxes, inheritance and succession taxes, estate taxes, federal and state income taxes, and other taxes to the extent applicable to Landlord’s general or net income from all sources, (ii) any items included as Operating Expenses, (iii) any items paid by Tenant under Section 4.5 of this

17

Lease, and (iv) transfer taxes associated with the sale or other transfer by Landlord of its interest in the Project.

4.2.6                        “Tenant’s Share” shall mean the percentage set forth in Section 6 of the Summary.

4.3                                 Allocation of Direct Expenses.

4.3.1                        Method of Allocation.  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 tenants of the Building and the tenants of the other buildings in the Project.  Accordingly, as set forth in Section 4.2 above, Direct Expenses (which consists 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 any other buildings in the Project) and such portion shall be the Direct Expenses for purposes of this Lease.  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.

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 Building Direct Expenses and Payment by Tenant.  Landlord shall give to Tenant following the end of each Expense Year, a statement (the “Statement”) which shall state the Building 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 deliver such Statement to Tenant on or before May 1 following the end of the Expense Year to which such Statement relates.  Upon receipt of the Statement for each Expense Year commencing or ending during the Lease Term, Tenant shall pay, within thirty (30) days after receipt of the Statement, 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 (an “Excess”), Tenant shall receive a credit in the amount of such Excess against Rent next due under this 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.  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, if Tenant’s Share of Direct Expenses is greater than the amount of Estimated Direct Expenses previously paid by Tenant to Landlord, Tenant shall, within thirty (30) days after receipt of the Statement, pay to Landlord such amount, and if Tenant paid more as Estimated Direct Expenses than the actual Tenant’s Share of Direct Expenses (again, an Excess), Landlord shall, within thirty (30) days, deliver a check payable to Tenant in the amount of such Excess.  The provisions of this Section 4.4.1 shall survive the expiration or earlier termination of the Lease Term.  Notwithstanding the immediately preceding sentence,

18

Tenant shall not be responsible for Tenant’s Share of any Building Direct Expenses attributable to any Expense Year which are first billed to Tenant more than two (2) calendar years after the Lease Expiration Date, provided that in any event Tenant shall be responsible for Tenant’s Share of Direct Expenses levied by any governmental authority or by any public utility companies at any time following the Lease Expiration Date which are attributable to any Expense Year.

4.4.2                        Statement of Estimated Building Direct Expenses.  In addition, Landlord shall give Tenant a yearly expense estimate statement (the “Estimate Statement”) which shall set forth in general major categories 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”).  Landlord shall use commercially reasonable efforts to deliver such Estimate Statement to Tenant on or before April 1 following the end of the Expense Year to which such Estimate Statement relates.  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, within thirty (30) days after receipt of the Estimate Statement, a fraction of the Estimated Direct Expenses for the then-current Expense Year (reduced by any amounts paid pursuant to the second to 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.  Throughout the Lease Term Landlord shall maintain books and records with respect to Building Direct Expenses in accordance with generally accepted real estate accounting and management practices, consistently applied.

4.5                                 Taxes and Other Charges for Which Tenant Is Directly Responsible.

4.5.1                        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.

4.5.2                        If the tenant improvements in the Premises, whether installed and/or paid for by Landlord or Tenant and whether or not affixed to the real property so as to become a part thereof, are assessed for real property tax purposes at a valuation higher than the valuation at which tenant improvements conforming to Landlord’s “building standard” in other space in the Building are assessed, then the Tax Expenses levied against Landlord or the property by reason

19

of such excess assessed valuation shall be deemed to be taxes levied against personal property of Tenant and shall be governed by the provisions of Section 4.5.1, above.

4.5.3                        Notwithstanding any contrary provision herein, Tenant shall pay prior to delinquency any (i) rent tax or sales tax, service tax, transfer tax or value added tax, or any other applicable tax on the rent or services herein or otherwise respecting this Lease, (ii) taxes assessed upon or with respect to the possession, leasing, operation, management, maintenance, alteration, repair, use or occupancy by Tenant of the Premises or any portion of the Project, including the Project parking facility; or (iii) taxes assessed upon this transaction or any document to which Tenant is a party creating or transferring an interest or an estate in the Premises.

4.5.4                        Tenant shall be liable for and shall pay directly to Landlord within thirty (30) days of being invoiced therefor, the actual cost, if any, incurred by Landlord’s for carrying, pursuant to the terms and conditions of Section 10.2, below, “Pollution Legal Liability Environmental Insurance.”

4.6                                 Landlord’s Books and Records.  Within two (2) years after receipt of a Statement by Tenant, if Tenant disputes the amount of Additional Rent set forth in the Statement, a determination as to the proper amount shall be made, at Tenant’s expense, by an independent certified public accountant (the “Accountant”) selected by Landlord and subject to Tenant’s reasonable approval, by inspecting Landlord’s records with respect to the Statement at Landlord’s offices, provided that Tenant is not then in default under this Lease (beyond any applicable notice and cure periods) and Tenant has paid all amounts required to be paid under the applicable Estimate Statement and Statement, as the case may be.  In connection with such inspection, the Accountant must agree in advance to follow Landlord’s reasonable rules and procedures regarding inspections of Landlord’s records, and shall execute a commercially reasonable confidentiality agreement regarding such inspection.  If such determination by the Accountant proves that Direct Expenses were overstated by more than five percent (5%), then the cost of the Accountant and the cost of such determination shall be paid for by Landlord.  Tenant’s failure to dispute the amount of Additional Rent set forth in any Statement within two (2) years of Tenant’s receipt of such Statement shall be deemed to be Tenant’s approval of such Statement and Tenant, thereafter, waives the right or ability to dispute the amounts set forth in such Statement.  Tenant hereby acknowledges that Tenant’s sole right to inspect Landlord’s books and records and to contest the amount of Direct Expenses payable by Tenant shall be as set forth in this Section 4.6, and Tenant hereby waives any and all other rights pursuant to Applicable Law to inspect such books and records and/or to contest the amount of Direct Expenses payable by Tenant.

5.3                                 CC&Rs.  Tenant shall comply with all recorded covenants, conditions, and restrictions currently affecting the Project.  Additionally, Tenant acknowledges that the Project may be subject to any future covenants, conditions, and restrictions (the “CC&Rs”) which Landlord, in Landlord’s discretion, deems reasonably necessary or desirable (provided, however, such amendments and/or modifications do not prohibit the Permitted Use in the Project and do not materially adversely interfere with Tenant’s use and enjoyment of the Premises), and Tenant agrees that this Lease shall be subject and subordinate to such CC&Rs.  Landlord shall have the right to require Tenant to execute and acknowledge, within fifteen (15) business days of a request by Landlord, a “Recognition of Covenants, Conditions, and Restriction,” in a form substantially similar to that attached hereto as Exhibit F, agreeing to and acknowledging the CC&Rs.

6.5                                 Landlord’s Assumption Of Maintenance.  Landlord shall have the right, after twenty-four (24) hours notice to Tenant, to inspect the Building, Building Systems, the Central Plant Area, and/or Tenant’s Books and Records, in order to ensure compliance with this Article 6.  In the event Tenant fails, in the reasonable judgment of Landlord, to provide the maintenance services (or cause the same to be provided) in accordance with the obligations set forth in this Article 6, Landlord shall deliver a written notice (a “Maintenance Failure Notice”) to Tenant stating with particularity the nature of such failure (such failure by Tenant to be known as a “Tenant Maintenance Failure”).  If such Tenant Maintenance Failure continues at the end of the fifth (5th) business day following the date of delivery of such Maintenance Failure Notice, then Landlord shall have the right to provide such maintenance and Tenant shall pay Landlord the cost thereof promptly upon being billed for same (including a percentage of the cost thereof sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such maintenance); provided, however, in the event of an emergency, Landlord may take such remedial action immediately following the delivery of the Maintenance Failure Notice.  In the event more than two (2) Tenant Maintenance Failures occur during any calendar year during the Lease Term, Landlord may, but need not, assume such repair and maintenance obligations on behalf of Tenant for the remainder of the Lease Term, in which case (i) Tenant shall pay Landlord the cost thereof promptly upon being billed for same, and (ii) Landlord’s management fee for the Project shall, notwithstanding the management fee set forth in Section 4.2.4(vi), be increased to five percent (5%).

6.6                                 Interruption of Use.  Except as otherwise provided in this Lease, Tenant agrees that Landlord shall not be liable for damages, by abatement of Rent or otherwise, for failure to furnish or delay in furnishing any service (including telephone and telecommunication services), or for any diminution in the quality or quantity thereof, when such failure or delay or diminution is occasioned, in whole or in part, by breakage, repairs, replacements, or improvements, by any strike, lockout or other labor trouble, by inability to secure electricity, gas, water, or other fuel at the Building or Project after reasonable effort to do so, by any riot or other dangerous condition, emergency, accident or casualty whatsoever, by act or default of Tenant or other parties, or by any other cause beyond Landlord’s reasonable control; and such failures or delays or diminution shall never be deemed to constitute an eviction or disturbance of Tenant’s use and possession of the Premises or relieve Tenant from paying Rent or performing any of its obligations under this Lease, except as otherwise provided in this Lease.  Furthermore, Landlord shall not be liable under any circumstances for consequential damages relating to the 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.

6.7                                 Rent Abatement.  If Landlord fails to perform the obligations required of Landlord under the TCCs of this Lease and such failure causes all or a portion of the Premises to be untenantable and unusable by Tenant and such failure relates to the nonfunctioning of the heat, ventilation, and air conditioning system in the Premises, the electricity in the Premises, the

nonfunctioning of the elevator service to the Premises, or a failure to provide access to the Premises, Tenant shall give Landlord notice (the “Initial Notice”), specifying such failure to perform by Landlord (the “Landlord Default”).  If Landlord has not cured such Landlord Default within five (5) business days after the receipt of the Initial Notice (the “Eligibility Period”), Tenant may deliver an additional notice to Landlord (the “Additional Notice”), specifying such Landlord Default and Tenant’s intention to ▇▇▇▇▇ the payment of Rent under this Lease.  If Landlord does not cure such Landlord Default within five (5) business days of receipt of the Additional Notice, Tenant may, upon written notice to Landlord, immediately ▇▇▇▇▇ Rent payable under this Lease for that portion of the Premises rendered untenantable and not used by Tenant, for the period beginning on the date five (5) business days after the Initial Notice to the earlier of the date Landlord cures such Landlord Default or the date Tenant recommences the use of such portion of the Premises.  Such right to ▇▇▇▇▇ Rent shall be Tenant’s sole and exclusive remedy at law or in equity for a Landlord Default.  Except as provided in this Section 6.4, nothing contained herein shall be interpreted to mean that Tenant is excused from paying Rent due hereunder.

ARTICLE 7

BUILDING STRUCTURE & PROJECT EXTERIOR REPAIRS

7.1                                 Landlord’s Maintenance Obligations.  Landlord shall repair, replace and maintain in a first-class condition and operating order the structural portions of the Building, including, without limitation, the foundation, floor slabs, Building skin and roof (not including the roof membrane), curtain wall (including gaskets and seals), exterior glass and mullions, columns, beams, shafts and stairwells (collectively, “Building Structure”), and all portions of the Project existing outside of the Building including, without limitation, the parking facilities, sidewalks, gutters, and landscaping and hardscaping; provided, however, for the purposes of this Article 7, the Building Structure shall not apply to the extent of any Alteration or other improvements thereto made by or on behalf of Tenant under the terms of this Lease or the Original Lease.  Notwithstanding anything in this Lease to the contrary, Tenant shall be required to repair the Building Structure to the extent caused due to Tenant’s use of the Premises for other than normal and customary implementation of the Permitted Use, unless and to the extent such damage is covered by insurance carried or required to be carried by Landlord pursuant to Article 10 and to which the waiver of subrogation is applicable (such obligation to the extent applicable to Tenant as qualified and conditioned will hereinafter be defined as the “BS Exception”).  While Landlord shall perform all of such work allocated to Landlord under this Section 7.1 (collectively, the “LL Maintenance Obligations”), the reasonable, actual costs related to Landlord’s performance of reasonably required maintenance included with such LL Maintenance Obligations shall be included in Operating Expenses (except to the extent such costs are incurred for Non-Reimbursable Capital Improvements).  Any entry of the Premises by Landlord in connection with the foregoing shall be done consistent with the terms of Article 27 of this Lease.  Tenant acknowledges that, Tenant shall, at Tenant’s own expense, pursuant to the TCCs of this Lease, including, without limitation Article 6 and Article 8 hereof, remain responsible for the maintenance, repair and replacement of all of the remaining portions of the Building (i.e., the Building Structure).Except as specifically set forth in Section 7.2 of this Lease, below, Tenant hereby waives any and all rights under and benefits of subsection 1 of Section

25

1932 and Sections 1941 and 1942 of the California Civil Code or under any similar law, statute, or ordinance now or hereafter in effect.

7.2                                 Tenant’s Right to Make Repairs.  Notwithstanding the provisions of Section 7.1, above, if Tenant provides notice to Landlord of an event or circumstance which requires the action of Landlord with respect to repair and/or maintenance as set forth in Section 7.1, above and Landlord fails to provide such action within (30) days after receipt of such notice, then Tenant may proceed to take the required action upon delivery of an additional ten (10) days notice to Landlord specifying that Tenant is taking such required action, and if such action was required under the TCCs of this Lease to be taken by Landlord, then Tenant shall be entitled to prompt reimbursement by Landlord of Tenant’s reasonable costs and expenses in taking such action; provided, however, notwithstanding such thirty (30) day period, Landlord shall use commercially reasonable efforts to expedite such repairs to ensure completion as soon as reasonably practicable.  In the event Tenant takes such action, Tenant shall use only those contractors used by Landlord in the Building for similar work unless such contractors are unwilling or unable to perform such work, in which event Tenant may utilize the services of any other qualified contractor which normally and regularly performs similar work in the Comparable Buildings.  If Landlord delivers to Tenant within thirty (30) days after receipt of Tenant’s invoice, a written objection to the payment of such invoice, setting forth with reasonable particularity Landlord’s reasons for its claim that such action did not have to be taken by Landlord pursuant to the TCCs of this Lease or that the charges are excessive (in which case Landlord shall pay the amount it contends would not have been excessive), then, as Tenant’s sole remedy, Tenant may proceed to institute legal proceedings against Landlord to collect the amount set forth in the subject invoice; provided that under no circumstances shall Tenant be allowed to (i) deduct such disputed amount from Rent, or (ii) terminate this Lease.  If Tenant receives a non-appealable final judgment against Landlord in connection with such legal proceedings, Tenant may deduct the amount of the judgment, not to exceed the amount of the unpaid portion of the relevant invoice, from the Base Rent next due and owing under this Lease; provided, however, Tenant may not deduct the amount of the judgment against more than fifty percent (50%) of Base Rent next due and owing (until such time as the entire amount of such judgment is deducted) to the extent following a foreclosure or a deed-in-lieu of foreclosure.

ARTICLE 8

ADDITIONS AND ALTERATIONS

8.1                                 Landlord’s Consent to Alterations.  Tenant may not make any improvements, alterations, additions, repairs or changes to the Premises or any mechanical, plumbing or HVAC facilities or systems pertaining to the Premises (collectively, the “Alterations”) without first procuring the prior written consent of Landlord to such Alterations, which consent shall be requested by Tenant not less than fifteen (15) business days prior to the commencement thereof, and which consent shall not be unreasonably withheld by Landlord, provided it shall be deemed reasonable for Landlord to withhold its consent to any Alteration which adversely affects the structural portions or the systems or equipment of the Building or is visible from the exterior of the Building.  Notwithstanding the foregoing, Tenant shall be permitted to make Alterations following fifteen (15) days notice to Landlord, but without Landlord’s prior consent, to the extent that such Alterations do not (i) involve the expenditure of more than $100,000.00 in the

26

aggregate in any Lease Year; (ii) adversely affect the systems and equipment of the Building or the Building Structure, or (iii) adversely affect the exterior appearance of the Building (the “Cosmetic Alterations”).  The construction of the initial improvements to the Premises shall be governed by the terms of the Tenant Work Letter and not the terms of this Article 8.

8.2                                 Manner of Construction.  Landlord may impose, as a condition of its consent to any and all Alterations or repairs of the Premises or about the Premises, such requirements as Landlord in its reasonable discretion may deem desirable; provided, however, such requirement shall at a minimum include, but not limited to, the following:  (i) the requirement that Tenant utilize for such purposes only contractors reasonably approved by Landlord, (ii) the requirement that upon Landlord’s request made at the time such consent is granted, Tenant shall, at Tenant’s expense, remove such Alterations upon the expiration or any early termination of the Lease Term and return the affected portion of the Premises to a building standard general laboratory improved condition consistent with the cGMP Standard and otherwise as reasonably determined by Landlord; (iii) the requirement that a copy of Tenant’s contract(s) with its contractors be delivered to Landlord prior to the commencement of any such construction (which contracts shall state that all change orders must be approved, in writing, by Landlord prior to implementation); (iv) Landlord’s review and approval of the final budget (contractor’s cost proposal) for such Alterations or repairs; and (v) the requirement that Tenant shall meet with Landlord, prior to the commencement of any construction, to discuss Landlord’s design parameters and code compliance issues.  Tenant shall construct such Alterations and perform such repairs in a good and workmanlike manner, in conformance with any and all applicable federal, state, county or municipal laws, rules and regulations and pursuant to a valid building permit, issued by the City of San Diego, all in conformance with Landlord’s construction rules and regulations.  In the event Tenant performs any Alterations in the Premises which require or give rise to governmentally required changes to the “Base Building,” as that term is defined below, then Landlord shall, at Tenant’s expense, make such changes to the Base Building.  The “Base Building” shall consist of the Building Structure.  In performing the work of any such Alterations, Tenant shall have the work performed in such manner so as not to obstruct access to the Project or any portion thereof, by any other tenant of the Project, and so as not to obstruct the business of Landlord or other tenants in the  Project.  Tenant shall not use (and upon notice from Landlord shall cease using) contractors, services, workmen, labor, materials or equipment that, in Landlord’s reasonable judgment, would disturb labor harmony with the workforce or trades engaged in performing other work, labor or services in or about the Building or the Common Areas.  In addition to Tenant’s obligations under Article 9 of this Lease, upon completion of any Alterations, Tenant agrees to cause a Notice of Completion to be recorded in the office of the Recorder of the County of San Diego in accordance with Section 3093 of the Civil Code of the State of California or any successor statute, and Tenant shall deliver to the Project construction manager a reproducible copy of the “as built” drawings of the Alterations, to the extent applicable, as well as all permits, approvals and other documents issued by any governmental agency in connection with the Alterations.

8.3                                 Payment for Improvements.  Tenant shall sign Landlord’s standard contractor’s rules and regulations to the extent the same are commercially reasonable.  Except with regard to Cosmetic Alterations for which there shall be no such charge, whether or not Tenant orders any work directly from Landlord, Tenant shall pay to Landlord an amount equal to one percent (1%)

27

of the cost of such work to compensate Landlord for all overhead, general conditions, fees and other costs and expenses arising from Landlord’s involvement with such work.

8.4                                 Construction Insurance.  In addition to the requirements of Article 10 of this Lease, in the event that Tenant makes any Alterations, prior to the commencement of such Alterations, Tenant shall provide Landlord with evidence that Tenant carries “Builder’s All Risk” insurance in an amount reasonably approved by Landlord covering the construction of such Alterations, and such other insurance as Landlord may reasonably require, it being understood and agreed that all of such Alterations shall be insured by Tenant pursuant to Article 10 of this Lease immediately upon completion thereof.  In addition, for any Alterations with an aggregate cost equal to or greater than $100,000.00 in any Lease Year, Tenant shall obtain a lien and completion bond or some alternate form of security reasonably satisfactory to Landlord in an amount sufficient to ensure the lien-free completion of such Alterations and naming Landlord as a co-obligee (“Alteration Security”); provided, however, if Tenant meets or exceeds one or both of the financial thresholds set forth in Sections 21.2.2.2(ii) and (iii) of this Lease, then Tenant shall not be required to obtain such Alteration Security.

8.5                                 Landlord’s Property.  Landlord and Tenant hereby acknowledges and agree that (i) all Alterations, improvements, fixtures, affixed equipment and/or appurtenances which may be installed or placed in or about the Premises, from time to time, shall be at the sole cost of Tenant and shall be and become the property of Landlord, except as more particularly set forth below, and (ii) the Tenant Improvements to be constructed in the Premises pursuant to the TCCs of the Tenant Work Letter shall, upon completion of the same, be and become a part of the Premises and the property of Landlord.  Notwithstanding the foregoing, and provided that (A) the same are not Tenant Improvements constructed pursuant to the terms of the Tenant Work Letter, and (B) Landlord has not previously identified the same as “must-remain” items pursuant to the procedure set forth below, Tenant may remove any other Alterations, improvements, fixtures and/or equipment which Tenant can substantiate to Landlord have not been paid for (in whole or in part) with any improvement allowance funds provided to Tenant by Landlord, provided Tenant repairs any damage to the Premises and Building caused by such removal and returns the affected portion of the Premises to a building standard general laboratory improved condition as reasonably determined by Landlord.  Furthermore, Landlord may, by written notice to Tenant prior to the end of the Lease Term, or given following any earlier termination of this Lease, require Tenant, at Tenant’s expense, to (i) remove any Alterations or improvements in the Premises installed pursuant to this Article 8, and/or (ii) remove any “Above Building Standard Tenant Improvements,” as that term is defined in Section 2.4 of the Tenant Work Letter, located within the Premises and replace the same with then existing “Building Standard Tenant Improvements,” as that term is defined in Section 2.3 of the Tenant Work Letter, and to repair any damage to the Premises and Building caused by such removal and returns the affected portion of the Premises to a building standard tenant improved condition as reasonably determined by Landlord; provided, however, if in connection with its request for Landlord’s approval for particular Alterations, (1) Tenant requests Landlord’s decision with regard to the removal of such Alterations, and (2) Landlord thereafter agrees in writing to waive the removal requirement when approving such Alterations, then Tenant shall not be required to so remove such Alterations; provided further, however, that Landlord may, in connection with Landlord’s approval for particular Alterations (or, in Landlord’s approval is not required or sought, then within thirty (30) days of Landlord being notified of such Alterations), identify particular

28

Alterations as those which must-remain in the Premises and become the property of Landlord.  If Tenant fails to complete such removal and/or to repair any damage caused by the removal of any Alterations or improvements in the Premises, and returns the affected portion of the Premises to a building standard tenant improved condition as determined by Landlord, then at Landlord’s option, either (X) Tenant shall be deemed to be holding over in the Premises and Rent shall continue to accrue in accordance with the terms of Article 16, below, until such work shall be completed, or (Y) Landlord may do so and may charge the cost thereof to Tenant.  Tenant hereby protects, defends, indemnifies and holds Landlord harmless from any liability, cost, obligation, expense or claim of lien in any manner relating to the violation of the foregoing provisions, which obligations of Tenant shall survive the expiration or earlier termination of this Lease.

ARTICLE 9

COVENANT AGAINST LIENS

Tenant shall keep the Project and Premises free from any liens or encumbrances arising out of the work performed, materials furnished or obligations incurred by or on behalf of Tenant, and shall protect, defend, indemnify and hold Landlord harmless from and against any claims, liabilities, judgments or costs (including, without limitation, reasonable attorneys’ fees and costs) arising out of same or in connection therewith.  Tenant shall give Landlord notice at least twenty (20) days prior to the commencement of any such work on the Premises (or such additional time as may be necessary under applicable laws) to afford Landlord the opportunity of posting and recording appropriate notices of non-responsibility.  Tenant shall remove any such lien or encumbrance by bond or otherwise within ten (10) days after notice by Landlord, and if Tenant shall fail to do so, Landlord may pay the amount necessary to remove such lien or encumbrance, without being responsible for investigating the validity thereof.  The amount so paid shall be deemed Additional Rent under this Lease payable upon demand, without limitation as to other remedies available to Landlord under this Lease.  Nothing contained in this Lease shall authorize Tenant to do any act which shall subject Landlord’s title to the Building or Premises to any liens or encumbrances whether claimed by operation of law or express or implied contract.  Any claim to a lien or encumbrance upon the Building or Premises arising in connection with any such work or respecting the Premises not performed by or at the request of Landlord shall be null and void, or at Landlord’s option shall attach only against Tenant’s interest in the Premises and shall in all respects be subordinate to Landlord’s title to the Project, Building and Premises.  Notwithstanding anything in this Article 9 to the contrary, Landlord hereby acknowledges and agrees that Tenant may grant a security interest to Tenant’s construction lender pursuant to the express terms and conditions of Section 5.5 of the Tenant Work Letter.

ARTICLE 10

INSURANCE

10.1                           Indemnification and Waiver.  Tenant hereby releases Landlord from all risk of damage to property or injury to persons in, upon or about the Premises from any cause whatsoever (other than Landlord’s and Landlord Parties’ negligence or willful misconduct) and agrees that Landlord, its partners, subpartners and their respective officers, agents, servants, employees, and independent contractors (collectively, “Landlord Parties”) shall not be liable to

29

Tenant for, and are hereby released from any responsibility to Tenant for, any damage either to person or property or resulting from the loss of use thereof, which damage is sustained by Tenant or by other persons claiming through Tenant (other than damage arising due to Landlord’s and Landlord Parties’ negligence or willful misconduct).  Tenant shall indemnify, defend, protect, and hold harmless the Landlord Parties from any and all loss, cost, damage, expense and liability (including without limitation court costs and reasonable attorneys’ fees) incurred in connection with or arising from any cause in or on the Premises (other than Landlord’s and Landlord Parties’ negligence or willful misconduct), any acts, omissions or negligence of Tenant or of any person claiming by, through or under Tenant, or of the contractors, agents, servants, employees, or licensees of Tenant (collectively, the “Tenant Parties”), in, on or about the Project or any breach of the TCCs of this Lease, either prior to, during, or after the expiration of the Lease Term, provided that the terms of the foregoing indemnity shall not apply to the negligence or willful misconduct of Landlord or any Landlord Party.  Should Landlord be named as a defendant in any suit brought against Tenant in connection with or arising out of Tenant’s occupancy of the Premises and subject to the indemnification provision hereinabove, Tenant shall pay to Landlord its costs and expenses incurred in such suit, including without limitation, its actual professional fees such as appraisers’, accountants’ and attorneys’ fees.  Further, Tenant’s agreement to indemnify Landlord pursuant to this Section 10.1 is not intended and shall not relieve any insurance carrier of its obligations under policies required to be carried by Tenant or Landlord pursuant to the provisions of this Lease, to the extent such policies cover the matters subject to Tenant’s indemnification obligations; nor shall they supersede any inconsistent agreement of the parties set forth in any other provision of this Lease.  The provisions of this Section 10.1 shall survive the expiration or sooner termination of this Lease with respect to any claims or liability arising in connection with any event occurring prior to such expiration or termination.  Notwithstanding anything to the contrary contained in this Lease, nothing in this Lease shall impose any obligations on Tenant or Landlord to be responsible or liable for, and each hereby releases the other from all liability for, consequential damages other than those consequential damages incurred by Landlord in connection with a holdover of the Premises by Tenant after the expiration or earlier termination of this Lease.

10.2                           Landlord’s Fire, Casualty and Liability Insurance.  Landlord shall carry commercial general liability insurance with respect to the Project and Building during the Lease Term, shall further insure the Project and Building Structure during the Lease Term against loss or damage due to fire and other casualties covered within the classification of fire and extended coverage, vandalism coverage and malicious mischief, sprinkler leakage, water damage and special extended coverage, as well as flood damage and additional hazards, and shall further carry rental interruption coverage for a period of one year.  Such coverage shall be in such amounts, from such companies, and on such other terms and conditions, as Landlord may from time to time reasonably determine; provided, however, such coverage shall be for the full replacement value of the Building Structure and the Project in compliance with all then-existing Applicable Laws.  Additionally, at the option of Landlord, such insurance coverage may include the risks of (i) earthquakes, (ii) one or more loss payee endorsements in favor of the holders of any mortgages or deeds of trust encumbering the interest of Landlord in the Building or the ground or underlying lessors of the Building, or any portion thereof, and (iii) ”Pollution Legal Liability Environmental Insurance,” as that term is set forth below; provided, however, that to the extent Tenant is not in default of this Lease (beyond any applicable notice and cure periods), Tenant shall have the option, upon thirty (30) days written notice to Landlord, to itself carry such

30

Pollution Legal Liability Environmental Insurance in lieu of Landlord carrying such insurance; provided further, however, to the extent Tenant elects to carry such Pollution Legal Liability Environment Insurance pursuant to the foregoing option, Tenant shall comply with the express coverage requirements set forth hereinbelow and such insurance coverage shall otherwise comply with the TCCs of Section 10.4, below.  Notwithstanding the foregoing provisions of this Section 10.2, the coverage and amounts of insurance carried by Landlord in connection with the Building shall, at a minimum, be comparable to the coverage and amounts of insurance which are carried by reasonably prudent landlords of Comparable Buildings, and Worker’s Compensation and Employer’s Liability coverage as required by applicable law.  Tenant shall, at Tenant’s expense, comply with all commercially reasonable insurance company requirements pertaining to the use of the Premises.  If Tenant’s conduct or use of the Premises causes any increase in the premium for such insurance policies then Tenant shall reimburse Landlord for any such increase. Tenant, at Tenant’s expense, shall comply with all rules, orders, regulations or requirements of the American Insurance Association (formerly the National Board of Fire Underwriters) and with any similar body.  For purposes of this Lease, the “Pollution Legal Liability Environmental Insurance” (aka an “Owner’s Policy” of environmental insurance) shall mean insurance (1) from an insurance carrier with a credit rating of no less than AAA, it being acknowledged and agreed by Landlord that, as of the date of this Lease, ▇▇▇▇▇▇, AIG, Chubb, Zurich and the XL Insurance Company currently satisfy such credit rating, and (2) providing, at a minimum, the following:  (a) an initial 5-year policy term (with successive 1-year terms renewable on a rolling annual basis, until such time as the policy term equals or exceeds the Lease Expiration Date), (b) $2,000,000 coverage per incident or occurrence, (c) $2,000,000 aggregate coverage, (d) a deductible or self-insured retention of no more than $25,000, and (e) coverage for: (A) known and unknown pre-existing conditions; (B) unknown and later discovered conditions; (C) on-site and off-site third-party claims for bodily injury or property damage; and (D) legal defense expenses.  Furthermore, the policy of insurance must include an automatic extended reporting period that provides the Insured a period of no less than sixty (60) days following the effective date of termination of coverage in which to provide written notice to the insurance carrier of claims first made and reported within the automatic extended reporting period.  All other terms, coverage, exclusions, or conditions of the policy shall be at Landlord’s sole and complete discretion.

10.3                           Tenant’s Insurance.  Tenant shall maintain the following coverages in the following amounts.

10.3.1                  Commercial General Liability Insurance covering the insured against claims of bodily injury, personal injury and property damage (including loss of use thereof) arising out of Tenant’s operations, and contractual liabilities (covering the performance by Tenant of its indemnity agreements) including a Broad Form endorsement covering the insuring provisions of this Lease and, to the extent consistent with commercially standard policies of such insurance coverage, the performance by Tenant of the indemnity agreements set forth in Section 10.1 of this Lease, for limits of liability not less than:

31

10.3.2                  Physical Damage Insurance covering (i) all office furniture, business and trade fixtures, office equipment, free-standing cabinet work, movable partitions, merchandise and all other items of Tenant’s property on the Premises installed by, for, or at the expense of Tenant, (ii) the Building Systems, the “Tenant Improvements,” as that term is defined in Section 2.1 of the Tenant Work Letter, and any other improvements which exist in the Premises as of the Lease Commencement Date (excluding the Base Building) (the “Original Improvements”), and (iii) all other improvements, alterations and additions to the Premises made by Tenant.  Such insurance shall be written on a “special cause of loss” physical loss or damage basis, for the full replacement cost value (subject to reasonable deductible amounts) new without deduction for depreciation of the covered items and in amounts that meet any co-insurance clauses of the policies of insurance and shall include coverage for damage or other loss caused by fire or other peril including, but not limited to, vandalism and malicious mischief, theft, water damage of any type (provided the following shall not require Tenant to carry flood insurance, which flood insurance may instead be carried by Landlord pursuant to Section 10.2, above), including sprinkler leakage, bursting or stoppage of pipes, and explosion.

10.3.3                  Worker’s Compensation and Employer’s Liability or other similar insurance pursuant to all applicable state and local statutes and regulations.

10.4                           Form of Policies.  The minimum limits of policies of insurance required of Tenant under this Lease shall in no event limit the liability of Tenant under this Lease.  Such insurance shall (i) name Landlord, and any other party the Landlord so specifies that has a material financial interest in the Project, as an additional insured, including Landlord’s managing agent, if any; (ii) specifically cover the liability assumed by Tenant under this Lease, including, but not limited to, Tenant’s obligations under Section 10.1 of this Lease to the extent consistent with commercially standard policies of such insurance coverage; (iii) be issued by an insurance company having a rating of not less than A-X in Best’s Insurance Guide or which is otherwise acceptable to Landlord and licensed to do business in the State of California; (iv) be primary insurance as to all claims thereunder and provide that any insurance carried by Landlord is excess and is non-contributing with any insurance requirement of Tenant; (v) be in form and content reasonably acceptable to Landlord; and (vi) provide that said insurance shall not be canceled or coverage materially changed unless ten (10) days’ prior written notice shall have been given to Landlord and any mortgagee of Landlord, the identity of whom has been provided to Tenant in writing.  Tenant shall deliver said policy or policies or certificates thereof to Landlord on or before the Lease Commencement Date and at least thirty (30) days before the expiration dates thereof.  In the event Tenant shall fail to procure such insurance, or to deliver such policies or certificate, Landlord may, at its option, after written notice to Tenant and Tenant’s failure to obtain such insurance within five (5) days thereafter, procure such policies for the account of Tenant, and the cost thereof shall be paid to Landlord within thirty (30) days after delivery to Tenant of bills therefor.

32

10.5                           Subrogation.  Landlord and Tenant intend that their respective property loss risks shall be borne by reasonable insurance carriers to the extent above provided, and, notwithstanding any provisions to the contrary set forth in this Lease, Landlord and Tenant hereby agree to look solely to, and seek recovery only from, their respective insurance carriers in the event of a property loss to the extent that such coverage is agreed to be provided hereunder.  The parties each hereby waive all rights and claims against each other for such losses, and waive all rights of subrogation of their respective insurers, provided such waiver of subrogation shall not affect the right to the insured to recover thereunder.  The parties agree that their respective insurance policies are now, or shall be, endorsed such that the waiver of subrogation shall not affect the right of the insured to recover thereunder, so long as no material additional premium is charged therefor (unless the other party agrees to pay such additional premium).

10.6                           Additional Insurance Obligations.  Tenant shall carry and maintain during the entire Lease Term, at Tenant’s sole cost and expense, increased amounts of the insurance required to be carried by Tenant pursuant to this Article 10 and such other reasonable types of insurance coverage and in such reasonable amounts covering the Premises and Tenant’s operations therein, as may be reasonably requested by Landlord, but in no event in excess of the amounts and types of insurance then being required by landlords of other Comparable Buildings.

10.7                           Risk Management Obligations.  Landlord and Tenant shall promptly advise each other as to (i) any alleged accidents or casualty known by the reporting party which are substantially likely to result in the assertion of a claim against the other party, and (ii) the occurrence of any substantial casualty damage to the Project known to the reporting party.  Landlord and Tenant shall notify each other promptly of any threatened or pending condemnation, rezoning or other governmental orders, proceedings or lawsuits involving the Project.

ARTICLE 11

DAMAGE AND DESTRUCTION

11.1                           Repair of Damage to Premises by Landlord.  If the Building Structure or any portions of the Project existing outside of the Building 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 (specifically including, without limitation, any requirement to obtain any license, clearance or other authorization of any kind required to enter into and restore the Premises issued by any governmental or quasi-governmental agency having jurisdiction over the use, storage, release or removal of “Hazardous Materials,” as that term is set forth in Section 29.33 of this Lease, below, in, on or about the Premises (collectively, the “Hazardous Materials Clearances”), which Hazardous Materials Clearances shall be obtained by Tenant), and subject to all other terms of this Article 11, restore the Building Structure and all such portions of the Project existing outside of the Building.  Such restoration shall be to substantially the same condition of the Building Structure and exterior Project components 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 exterior Project components deemed desirable by Landlord, which are consistent with the character of the

33

Project, provided that access to the Premises and any common restrooms serving the Premises shall not be materially impaired.  Upon the occurrence of any damage to the Premises, Tenant shall, at its sole cost and expense, repair any injury or damage to the Building Systems, Tenant Improvements and the Original Improvements installed in the Premises and shall return such Building Systems, Tenant Improvements and Original Improvements to the condition existing immediately prior to such casualty (provided such Building Systems, Tenant Improvements and Original Improvements were properly maintained pursuant to the TCCs of this Lease prior to such casualty), except for modifications required by “Applicable Laws,” as that term is set forth in Article 24 of this Lease.  Prior to the commencement of construction, Tenant shall submit to Landlord, for Landlord’s review and approval, all plans, specifications and working drawings relating thereto, and Tenant shall select the contractors, subject to Landlord’s reasonable approval, to perform such improvement work.  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 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; provided further, however, that if any Hazardous Materials Clearances are required to be obtained by Tenant before such restoration can begin, such abatement of Rent shall continue for only so long as Tenant, in Landlord’s reasonable judgment, diligently pursues obtaining such required Hazardous Materials Clearances.  Tenant’s right to rent abatement pursuant to the preceding sentence shall terminate as of the date which is reasonably determined by Landlord to be the date Tenant should have completed repairs to the Premises assuming Tenant used reasonable due diligence in connection therewith.

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 Building Structure and/or exterior Project components, 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 Structure or exterior Project components shall be damaged by fire or other casualty or cause, whether or not the Premises are affected, 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 the insurance policies Landlord is required to carry pursuant to the TCCs of this Lease; (iv) Landlord cannot, pursuant to the applicable laws then in effect, rebuild the Building Structure or exterior Project components so that they will be substantially the same structurally or architecturally; or (v) 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, in the reasonable opinion of Landlord, 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.  Furthermore, if neither Landlord nor Tenant has terminated this Lease, and the repairs are not actually completed within such 180-day period, Tenant shall have the right to terminate this Lease during the first five (5) business days of each calendar month following the end of such period until such time as the repairs are complete, by notice to Landlord (the “Damage Termination Notice”), effective as of a date set forth in the Damage Termination Notice (the “Damage Termination Date”), which Damage Termination Date shall not be less than ten (10) business days following the end of each such month.  Notwithstanding the foregoing, if Tenant delivers a Damage Termination Notice to Landlord, then Landlord shall have the right to suspend the occurrence of the Damage Termination Date for a period ending thirty (30) days after the Damage Termination Date set forth in the Damage Termination Notice by delivering to Tenant, within five (5) business days of Landlord’s receipt of the Damage Termination Notice, a certificate of Landlord’s contractor responsible for the repair of the damage certifying that it is such contractor’s good faith judgment that the repairs shall be substantially completed within thirty (30) days after the Damage Termination Date.  If repairs shall be substantially completed prior to the expiration of such thirty-day period, then the Damage Termination Notice shall be of no force or effect, but if the repairs shall not be substantially completed within such thirty-day period, then this Lease shall terminate upon the expiration of such thirty-day period.  At any time, from time to time, after the date occurring sixty (60) days after the date of the damage, Tenant may request that Landlord inform Tenant of Landlord’s reasonable opinion of the date of completion of the repairs and Landlord shall respond to such request within five (5) business days.  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) as a result of the damage, Tenant cannot reasonably conduct business from the Premises; and, (c) as a result of the damage to the Project, Tenant does not occupy or use the Premises at all.  In the event this Lease is terminated in accordance with the terms of this Section 11.2, Tenant shall assign to Landlord (or to any party designated by Landlord) all insurance proceeds payable to Tenant under Tenant’s insurance required under Section 10.3.2 of this Lease; provided, however, that notwithstanding anything to the contrary set forth above, Tenant shall be entitled to retain a portion of such proceeds equal to the then-remaining unamortized amount (based on a straight-line amortization over the initial Lease Term) of the “Initial TI Disbursement” and the “Over-Allowance Amount,” as those terms are set forth in Sections 2.2.2.1 and 4.2.1, respectively, of the Tenant Work Letter.

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.

35

ARTICLE 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.

ARTICLE 13

CONDEMNATION

If the whole or any part of the Premises or the Building 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 or Building, or if Landlord shall grant a deed or other instrument in lieu of such taking by eminent domain or condemnation, Landlord shall have the option to terminate this Lease effective as of the date possession is required to be surrendered to the authority.  If more than fifty percent (50%) of the rentable square feet of the Premises is taken, or if access to the Premises is substantially impaired, in each case for a period in excess of one hundred eighty (180) days, 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 (i) Tenant’s personal property, and (ii) improvements and fixtures belonging to Tenant and removable by Tenant upon expiration of the Lease Term pursuant to the TCCs 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

36

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.

ARTICLE 14

ASSIGNMENT AND SUBLETTING

14.1                           Transfers.  Tenant shall not, without the prior written consent of Landlord as set forth more particularly in Section 14.2, below, 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, including all existing operative documents to be executed to evidence such Transfer or the agreements incidental or related to such Transfer, (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 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 and (v) an executed estoppel certificate from Tenant in the form attached hereto as Exhibit E.  Any Transfer 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, within thirty (30) days after written request by Landlord, reimburse Landlord for all reasonable and actual out-of-pocket third-party costs and expenses incurred by Landlord in connection with its review of a proposed Transfer; provided that such costs and expenses shall not exceed One Thousand Five Hundred and No/100 Dollars ($1,500.00) for a Transfer in the ordinary course of business.  Landlord and Tenant hereby agree that a proposed Transfer shall not be considered “in the ordinary course of business” if such Transfer involves the review of

37

documentation by Landlord on more than two (2) occasions with regard to a single proposed Transfer.

14.2                           Landlord’s Consent.  Landlord shall not unreasonably withhold 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 intends to use the Subject Space for purposes which are not permitted under this Lease;

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

14.2.4                  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;

14.2.5                  The proposed Transfer would cause a violation of another lease for space in the Project, or would give an occupant of the Project a right to cancel its lease;

14.2.6                  The terms of the proposed Transfer will allow the Transferee to exercise a right of renewal, right of expansion, right of first offer, or other similar right held by Tenant (or will allow the Transferee to occupy space leased by Tenant pursuant to any such right);

14.2.7                  Either the proposed Transferee, or any person or entity which directly or indirectly, controls, is controlled by, or is under common control with, the proposed Transferee, (i) occupies space in the Project at the time of the request for consent, or (ii) is negotiating with Landlord to lease space in the Project at such time, or (iii) has negotiated with Landlord during the six (6)-month period immediately preceding the Transfer Notice, and Landlord has available space in the Project suitable for such proposed Transferee; or

14.2.8                  The Transferee does not intend to occupy the entire Premises and conduct its business therefrom for a substantial portion of the term of the Transfer.

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 (i) such that Landlord would initially have been entitled to refuse its consent to such Transfer under this Section 14.2, or (ii) which would cause the proposed Transfer to be more favorable to the Transferee than the

38

terms set forth in Tenant’s original Transfer Notice, 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 declaratory judgment and an injunction for the relief sought without any monetary damages, 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.  Tenant shall indemnify, defend and hold harmless Landlord from any and all liability, losses, claims, damages, costs, expenses, causes of action and proceedings involving any third party or parties (including without limitation Tenant’s proposed subtenant or assignee) who claim they were damaged by Landlord’s wrongful withholding or conditioning of Landlord’s consent, unless a court of competent jurisdiction determines that Landlord was wrongful in its withholding or conditioning of its consent.

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, after deducting the reasonable expenses incurred by Tenant for (i) any changes, alterations and improvements to the Premises in connection with the Transfer, (ii) any free base rent reasonably provided to the Transferee, and (iii) any commercially reasonable brokerage commissions and legal fees in connection with the Transfer.  “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.  In the calculations of the Rent (as it relates to the Transfer Premium calculated under this Section 14.3), and the Transferee’s Rent and Quoted Rent under Section 14.2 of this Lease, the Rent paid during each annual period for the Subject Space, and the Transferee’s Rent and the Quoted Rent, shall be computed after adjusting such rent to the actual effective rent to be paid,  taking into consideration any and all leasehold concessions granted in connection therewith, including, but not limited to, any rent credit and improvement allowance.  For purposes of calculating any such effective rent all such concessions shall be amortized on a straight-line basis over the relevant term.

14.4                           Landlord’s Option as to Subject Space.  In the event that a proposed Transfer, if consented to, would cause fifty percent (50%) or more of the Premises to be subleased or assigned to a party other than Original Tenant and/or its Affiliates, then notwithstanding anything to the contrary contained in this Article 14, Notwithstanding anything to the contrary contained in this Article 14, Landlord shall have the option, by giving written notice to Tenant within thirty (30) days after receipt of any Transfer Notice, to recapture the Subject Space.  Such recapture notice shall cancel and terminate this Lease with respect to the Subject Space as of the date stated in the Transfer Notice as the effective date of the proposed Transfer until the last day

39

of the term of the Transfer as set forth in the Transfer Notice (or at Landlord’s option, shall cause the Transfer to be made to Landlord or its agent, in which case the parties shall execute the Transfer documentation promptly thereafter).  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 the Subject Space under this Section 14.4, then, provided Landlord has consented to the proposed Transfer, Tenant shall be entitled to proceed to transfer the Subject Space to the proposed Transferee, subject to provisions of this Article 14.

14.5                           Effect of Transfer.  If Landlord consents to a Transfer, (i) the TCCs 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 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 five percent (5%), 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, 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 a nationally recognized exchange or over the counter), (A) the merger, consolidation or other reorganization of Tenant in which the holders of Tenant’s outstanding voting stock immediately prior to such transaction own, immediately after such transaction, securities representing less than fifty percent (50%) of the voting power of the corporation or other entity surviving such transaction, (B) the sale or other transfer by the Tenant of an aggregate of fifty percent (50%) or more of the voting shares of Tenant in a single transaction or series of transactions, within any twelve (12)-month period (other than in connection with a capital raising transaction involving the sale of capital stock of Tenant to bona fide third-party investors), or (C) the sale, mortgage, exclusive license, hypothecation or pledge of all or substantially all of the value of the unencumbered assets of Tenant in a single transaction or series of transactions within a twelve (12)-month period.  Notwithstanding anything to the contrary set forth in this Article 14 to the contrary, in no event shall an offering of stock to (1) third parties by means of a public offering (either an initial public offering or a subsequent public

40

offering) through a recognized stock market, or (2) in connection with research and development partnerships or collaborative agreements, constitute a “Transfer.”

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 canceled 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, to the extent the Original Tenant in not then in default under this Lease (beyond any applicable notice and cure periods), an assignment or subletting of all or a portion of the Premises to (i) an affiliate of Tenant (an entity which is controlled by, controls or is under common control, as such term is defined in California General Corporations Code (“CGCC”) Sections 160 and 5045, with, Tenant), (ii) an entity which merges with or acquires or is acquired by, Tenant or a parent of Tenant, as defined in CGCC Sections 175 and 5064, or a subsidiary, as defined in CGCC Sections 189 and 5073, of Tenant’s parent or Affiliate, or (iii) a transferee of substantially all of the assets of Tenant (collectively, an “Affiliate”) along with any other entity which will qualify as an “affiliate” under CGCC 150 and 5031, shall not be deemed a Transfer under this Article 14, provided that Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any documents or information reasonably requested by Landlord regarding such assignment or sublease or such Affiliate, and such assignment or sublease is not a subterfuge by Tenant to avoid its obligations under this Lease, or otherwise “releases” the Original Tenant from such obligations.

ARTICLE 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

41

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 Section 8.5, this Article 15 and Section 29.33, 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, business 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.

ARTICLE 16

HOLDING OVER

If Tenant holds over after the expiration of the Lease Term or earlier termination thereof, with or without 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, and in such case Rent shall be payable at a monthly rate equal to the product of (i) the Rent applicable during the last rental period of the Lease Term under this Lease, and (ii) a percentage equal to one hundred fifty percent (150%) during the first two (2) months immediately following the expiration or earlier termination of the Lease Term, and two hundred percent (200%) thereafter.  Such month-to-month tenancy 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.

42

ARTICLE 17

ESTOPPEL CERTIFICATES

Within ten (10) 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 E, attached hereto (or such other form as may be reasonably 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 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 commercially reasonable instruments may be reasonably required for such purposes.  At any time during the Lease Term, Landlord may require Tenant to provide Landlord with its most recently prepared financial statement and financial statements of the two (2) years prior to the most recently prepared financial statement year.  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 commercially reasonable 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.  Any such financial statement or other information which is marked “confidential” or “company secret(s)” (or is otherwise similarly marked by Tenant) shall be confidential and shall not be disclosed by Landlord to any third party (other than its partners, administrators, consultants, financial, legal and a prospective or current purchaser, mortgagee, or ground or underlying lessor of the Building or the Project, a prospective Transferee, and except as required by applicable law or in connection with a dispute or litigation hereunder or as required by a subpoena) except as specifically provided in this Article 17 and then only if the person to whom disclosure is made first agrees to be bound by the requirements of this Article 17.

ARTICLE 18

SUBORDINATION

Subject to Tenant’s receipt of an appropriate non-disturbance agreement(s) as set forth below, this Lease shall be subject and subordinate to all present and 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.  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

43

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 TCCs of this Lease to be observed and performed by Tenant.  Landlord’s delivery to Tenant of a fully executed commercially reasonable non-disturbance agreement(s) (the “Nondisturbance Agreement”) in favor of Tenant from any such ground lessor, mortgage holders or lien holders of Landlord who later come into existence at any time prior to the expiration of the Lease Term shall be in consideration of, and a condition precedent to, Tenant’s agreement to be bound by the terms and conditions of this Article 18; provided Tenant shall execute and return such Nondisturbance Agreement to Landlord within ten (10) days of its receipt thereof.  Nothing contained herein shall require Tenant to waive any of Landlord’s obligations under this Lease, including, without limitation, Landlord’s obligation to fund the Improvement Allowance (and Tenant’s offset rights for such failure).  Landlord’s interest herein may be assigned as security at any time to any lienholder.  Tenant shall, within four (4) 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.

ARTICLE 19

DEFAULTS; REMEDIES

19.1                           Events of Default.  The occurrence of any of the following shall constitute a default of this Lease by Tenant:

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, within five (5) business days after Tenant’s receipt from Landlord of written notice that the same was not paid when due; 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, but in no event exceeding a period of time in excess of sixty (60) days after written notice thereof from Landlord to Tenant; or

19.1.3                  To the extent permitted by law, a general assignment by Tenant or any guarantor of this Lease for the benefit of creditors, or the taking of any corporate action in furtherance of bankruptcy or dissolution whether or not there exists any proceeding under an insolvency or bankruptcy law, or the filing by or against Tenant or any guarantor of any

44

proceeding under an insolvency or bankruptcy law, unless in the case of a proceeding filed against Tenant or any guarantor the same is dismissed within sixty (60) days, or the appointment of a trustee or receiver to take possession of all or substantially all of the assets of Tenant or any guarantor, unless possession is restored to Tenant or such guarantor within thirty (30) days, or any execution or other judicially authorized seizure of all or substantially all of Tenant’s assets located upon the Premises or of Tenant’s interest in this Lease, unless such seizure is discharged within thirty (30) days; or

19.1.4                  Intentionally Omitted; or

19.1.5                  The failure by Tenant to observe or perform according to the provisions of Section 5.2, or 8.4 of this Lease, 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 event of 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:

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

(b)                                 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

(c)                                  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

(d)                                 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

45

(e)                                  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(a) and (b), 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(c), 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                           Form of Payment After Default.  Following the occurrence of an event of default by Tenant, Landlord shall have the right to require that any or all subsequent amounts paid by Tenant to Landlord hereunder, whether to cure the default in question or otherwise, be paid in the form of cash, money order, cashier’s or certified check drawn on an institution acceptable to Landlord, or by other means approved by Landlord, notwithstanding any prior practice of accepting payments in any different form.

19.5                           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

46

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.

19.6                           Landlord Default.  Notwithstanding anything to the contrary set forth in this Lease, Landlord shall be in default in the performance of the obligations required to be performed by Landlord pursuant to this Lease (i) if Landlord fails to timely fulfill its obligation to fund any portion of the Improvement Allowance pursuant to the terms set forth in the Tenant Work Letter or in the First Amendment Work Letter (which is to be attached to the First Amendment to Amended and Restated Office Lease), but only to the extent Landlord does not (A) subsequently cure such failure within twenty (20) business days following its receipt of written notice of such failure from Tenant (a “Payment Failure Notice”), or (B) deliver notice (a “Refusal Notice”) to Tenant within such twenty (20) business day period explaining (with reasonable specificity) Landlord’s reasons supporting Landlord’s position that the amounts described in the Payment Failure Notice are not, in fact, then due and payable by Landlord (in which case Landlord shall promptly fund the amount of the Improvement Allowance, if any, that Landlord does not contest is then due and payable by Landlord), or (ii) if Landlord fails to perform any other such obligation within thirty (30) days after the receipt of notice from Tenant specifying in detail Landlord’s failure to perform; provided, however, if the nature of Landlord’s obligation is such that more than thirty (30) days are required for its performance, then Landlord shall not be in default under this Lease if it shall commence such performance within such thirty (30) day period and thereafter diligently pursues the same to completion.  Upon any such default by Landlord under this Lease, Tenant may, except as otherwise specifically provided in this Lease to the contrary, exercise any of its rights provided at law or in equity.  Any award from a court or arbitrator in favor of Tenant requiring payment by Landlord which is not paid by Landlord within the time period directed by such award, may be offset by Tenant from Rent next due and payable under this Lease; provided, however, Tenant may not deduct the amount of the award against more than fifty percent (50%) of Base Rent next due and owing (until such time as the entire amount of such judgment is deducted).

ARTICLE 20

COVENANT OF QUIET ENJOYMENT

ARTICLE 21

SECURITY DEPOSIT; LETTER OF CREDIT

21.1                           Security Deposit.  The amount of the Security Deposit shall equal Three Hundred Fifty-Five Thousand Seven Hundred Twenty-Seven and 60/100 Dollars ($355,727.60), as set forth in Section 8 of the Summary.  Landlord and Tenant acknowledge that, in accordance with the Original Lease, Tenant has previously delivered the sum of One Hundred Sixty-Six Thousand Eighteen and 27/100 Dollars ($166,018.27) to Landlord as security for the faithful performance by Tenant of the terms, covenants and conditions of the Lease.  Concurrently with Tenant’s execution of this Lease, Tenant shall deposit with Landlord an additional amount equal to One Hundred Eighty-Nine Thousand Seven Hundred Nine and 33/100 Dollars ($189,709.33), and the resulting total amount shall be held by Landlord as security for the faithful performance by Tenant of all of its obligations under this Lease.  If Tenant defaults 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 sixty (60) days following the expiration of the Lease Term.  Tenant shall not be entitled to any interest on the Security Deposit.  Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, or any successor statute.

21.2                           Letter of Credit.

21.2.1                  Delivery of Letter of Credit.  As additional security for Tenant’s obligations under this Lease, Tenant shall deliver to Landlord, as set forth below, an unconditional, clean, irrevocable letter of credit (the “L-C”) in an amount as set forth in Section 21.2.2, below (the “L-C Amount”), which L-C shall be issued by a money-center bank (a bank which accepts deposits, maintains accounts, has a local Southern California office which will negotiate a letter of credit, and whose deposits are insured by the FDIC) reasonably acceptable to Landlord, and which L-C shall be in the form of Exhibit G, attached hereto.  Tenant shall pay all expenses, points and/or fees incurred by Tenant in obtaining the L-C.  Landlord and Tenant acknowledge that, in accordance with Article 21 of the Original Office Lease, Tenant has previously delivered an L-C in the amount of $1,549,613.56 (the “Existing L-C”) to Landlord as security for the faithful performance by Tenant of the terms, covenants and conditions of the Original Lease.  On or before the earlier to occur of (i) January 1, 2007, and (ii) the date of the first distribution of any portion of the Improvement Allowance pursuant to Section 2 of the Tenant Work Letter attached hereto as Exhibit B, Tenant shall amend the Existing L-C to increase the amount available thereunder to $3,450,427.20 (the “Amended L-C”), which Amended L-C shall be in the form, and subject to all the terms, set forth in this Section 21.2.

48

21.2.2                  L-C Amount.

21.2.2.1         Calculation of L-C Amount.  For purposes of this Lease, the “L-C Amount” shall initially be $3,450,427.20; provided, however, that commencing on February 1, 2008, and continuing for the remainder of the Lease Term, the L-C Amount shall be increased to an amount equal to twelve (12) months of the then-current Monthly Installment of Base Rent for the 10421 Building.

21.2.2.2         Conditional Increase/Reduction of L-C Amount.  Landlord and Tenant hereby acknowledge and agree that the L-C Amount is subject to increase and reduction throughout the Lease Term at the end of each financial quarter as set forth in this Section 21.2.2.2.  The starting L-C Amount shall be as set forth in Section 21.2.2.1, above.  Thereafter, the actual amount of the L-C posted by Tenant shall be equal to the L-C Amount, as such L-C Amount shall be reduced as follows:

(i) to the extent that Tenant maintains a “Working Capital,” as defined below, in excess of Thirty Million and No/100 Dollars ($30,000,000.00) for four (4) consecutive financial quarters during the Lease Term, a reduction of fifty percent (50%);

(ii) to the extent that Tenant maintains a Working Capital in excess of Thirty Million and No/100 Dollars ($30,000,000.00) for eight (8) consecutive financial quarters during the Lease Term, a reduction of one hundred percent (100%);

(iii) to the extent that Tenant maintains a Working Capital in excess of Fifty Million and No/100 Dollars ($50,000,000.00) for four (4) consecutive financial quarters during the Lease Term, a reduction of one hundred percent (100%).

As soon as reasonably practical following the end of each financial quarter during the Lease Term, the L-C Amount shall be recalculated pursuant to the terms of Section 21.2.2.1, above, and any percentage reductions, which are applicable to the L-C pursuant to subparagraphs (i) through (iii), above, shall be applied in order to determine the then-existing amount of L-C which Tenant is required to post (the “Required L-C Amount”).  In the event the determined Required L-C Amount is less than the amount of the actual L-C then-posted by Tenant, Tenant shall have the right to cause the amount of the then-current L-C to be reduced to the Required L-C Amount, and Landlord shall timely execute and deliver such commercially reasonable documents to the issuer(s) of the L-C as are presented to Landlord by such issuer(s) and as may be reasonably necessary to effectuate the change to the Required L-C Amount.  Likewise, in the event that the Required L-C Amount is greater than the amount of the L-C then posted by Tenant, Tenant shall upon its receipt of written notice from Landlord (the “Reestablishment Notice”), cause the amount of the then-current L-C to be increased to equal the Required L-C Amount.  In addition, in the event that, following the completion of each financial quarter throughout the Lease Term (A) Tenant fails to deliver timely the unaudited quarterly financial statements, or the annual audited financial statements required for Tenant to make a determination with regard to such Required Thresholds, (B) Tenant is in economic default under

49

the Lease (beyond any applicable notice and cure periods) more than twice during the immediately preceding twelve (12) months, or (C) following any reduction of the L-C Amount under the terms of subparagraphs (i), (ii) or (iii), above, Tenant fails during any one (1) financial quarter thereafter to maintain a Working Capital in excess of Thirty Million and No/100 Dollars ($30,000,000.00), then Tenant shall, upon receipt of a Reestablishment Notice, cause the L-C to be reestablished with the then applicable L-C Amount (as determined in accordance with the terms of Section 22.2.2.1, above).  The L-C Amount shall thereafter be subject to conditional reduction as set forth herein.  For purposes of this Section 21.2.2, “Working Capital,” means then-current assets of Tenant less then-current liabilities from Tenant’s previous quarterly financial statements, which Working Capital shall include then-current receivables (zero (0) to sixty (60) days only).  In connection with this Section 21.2.2, Tenant shall provide Landlord (1) Tenant’s current financial statements (applicable to the financial quarter which just ended) certified by Tenant’s Chief Executive Officer and Tenant’s Chief Financial Officer, within thirty (30) business days following the end of each financial quarter during the Lease Term, (2) Tenant’s current annual financial statement (applicable to the financial year which just ended) audited and certified by an independent certified public accountant, within one hundred twenty (120) days following the end of each financial year during the Lease Term, and (3) a disclosure statement of any material adverse changes in Tenant’s business.  The financial thresholds set forth in subparagraphs (i) through (iii), above, are, collectively, the “Required Thresholds.”

21.2.3                  FAILURE TO REINSTATE; LIQUIDATED DAMAGES.  IN THE EVENT THAT TENANT FAILS, WITHIN TWENTY (20) DAYS FOLLOWING TENANT’S RECEIPT OF A REESTABLISHMENT NOTICE, TO CAUSE THE L-C TO BE REESTABLISHED IN THE REQUIRED L-C AMOUNT, THEN TENANT’S MONTHLY INSTALLMENT OF BASE RENT SHALL BE INCREASED BY ONE HUNDRED FIFTY PERCENT (150%) OF ITS THEN EXISTING LEVEL DURING THE PERIOD COMMENCING ON THE DATE WHICH IS TWENTY (20) DAYS AFTER TENANT’S RECEIPT OF SUCH REESTABLISHMENT NOTICE AND ENDING ON THE EARLIER TO OCCUR OF (I) THE DATE SUCH L-C IS REESTABLISHED PURSUANT TO THE TERMS OF THIS SECTION 21.2, OR (II) THE DATE WHICH IS NINETY (90) DAYS AFTER THE DATE OF SUCH REESTABLISHMENT NOTICE.  IN THE EVENT THAT TENANT FAILS, DURING SUCH NINETY (90) DAY PERIOD FOLLOWING THE DATE OF THE REESTABLISHMENT NOTICE, TO CAUSE THE L-C TO BE REESTABLISHED IN THE REQUIRED L-C AMOUNT, THEN TENANT’S MONTHLY INSTALLMENT OF BASE RENT SHALL BE INCREASED BY TWO HUNDRED PERCENT (200%) OF ITS THEN EXISTING LEVEL DURING THE PERIOD COMMENCING ON THE DATE WHICH IS NINETY (90) DAYS AFTER THE DATE OF SUCH REESTABLISHMENT NOTICE AND ENDING ON THE DATE SUCH L-C IS RE-ISSUED/REESTABLISHED PURSUANT TO THE TERMS OF THIS SECTION 21.2. THE PARTIES AGREE THAT IT WOULD BE IMPRACTICABLE AND EXTREMELY DIFFICULT TO ASCERTAIN THE ACTUAL DAMAGES SUFFERED BY LANDLORD AS A RESULT OF TENANT’S FAILURE TO TIMELY REESTABLISH THE L-C FOLLOWING THE REESTABLISHMENT NOTICE AS REQUIRED IN THIS SECTION 21.2, AND THAT UNDER THE CIRCUMSTANCES EXISTING AS OF THE DATE OF THIS LEASE, THE LIQUIDATED DAMAGES PROVIDED FOR IN THIS SECTION 21.2.3 REPRESENT A REASONABLE ESTIMATE OF THE DAMAGES WHICH LANDLORD WILL INCUR AS A RESULT OF SUCH FAILURE, PROVIDED, HOWEVER, THAT THIS PROVISION SHALL NOT WAIVE OR AFFECT

50

LANDLORD’S RIGHTS AND TENANT’S INDEMNITY OBLIGATIONS UNDER OTHER SECTIONS OF THIS LEASE (EXCEPT THAT THE PARTIES SPECIFICALLY AGREE THAT THE FOREGOING PROVISION WAS AGREED TO IN LIEU OF MAKING FAILURE TO RE-ESTABLISH THE L-C A DEFAULT UNDER THE LEASE).  THE PARTIES ACKNOWLEDGE THAT THE PAYMENT OF SUCH LIQUIDATED DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY WITHIN THE MEANING OF CALIFORNIA CIVIL CODE SECTION 3275 OR 3369, BUT IS INTENDED TO CONSTITUTE LIQUIDATED DAMAGES TO LANDLORD PURSUANT TO CALIFORNIA CIVIL CODE SECTION 1671.  THE PARTIES HAVE SET FORTH THEIR INITIALS BELOW TO INDICATE THEIR AGREEMENT WITH THE LIQUIDATED DAMAGES PROVISION CONTAINED IN THIS SECTION 21.2.3.

21.2.4                  Application of Letter of Credit.  The L-C shall be held by Landlord as security for the faithful performance by Tenant of all the TCCs of this Lease to be kept and performed by Tenant during the Lease Term.  The L-C shall not be mortgaged, assigned or encumbered in any manner whatsoever by Tenant without the prior written consent of Landlord.  If Tenant defaults with respect to any provisions of this Lease, including, but not limited to, the provisions relating to the payment of Rent, or if Tenant fails to renew the L-C at least thirty (30) days before its expiration, Landlord may, but shall not be required to, draw upon all or any portion of the L-C for payment of any Rent or any other sum in default, or for the payment of any amount that Landlord may reasonably spend or may become obligated to spend by reason of Tenant’s default, or to compensate Landlord for any other loss or damage that Landlord may suffer by reason of Tenant’s default.  The use, application or retention of the L-C, or any portion thereof, by Landlord shall not prevent Landlord from exercising any other right or remedy provided by this Lease or by law, it being intended that Landlord shall not first be required to proceed against the L-C and shall not operate as a limitation on any recovery to which Landlord may otherwise be entitled.  Any amount of the L-C which is drawn upon by Landlord, but is not used or applied by Landlord, shall be held by Landlord and deemed a security deposit (the “L-C Security Deposit”) and, in connection with such L-C Security Deposit, Tenant hereby waives the provisions of Section 1950.7 of the California Civil Code, or any successor statute.  If any portion of the L-C is drawn upon and used or applied by Landlord, Tenant shall, within ten (10) days after written demand therefor, either (i) deposit cash with Landlord (which cash shall constitute part of the L-C Security Deposit) in an amount sufficient to cause the sum of the L-C Security Deposit and the amount of the remaining L-C to be equivalent to the amount of the L-C then required under this Lease (and if any portion of the L-C Security Deposit is thereafter used or applied, Tenant shall restore such L-C Security Deposit to the amount then required under this Lease pursuant to the foregoing), or (ii) reinstate the L-C to the amount then required under this Lease, in which case any unused portion of the then-existing L-C Security Deposit shall be returned to Tenant.  Tenant acknowledges that Landlord has the right to transfer or mortgage its interest in the Project and in this Lease and Tenant agrees that in the event of any such transfer or mortgage, Landlord shall have the right to transfer or assign the L-C Security Deposit and/or the

51

L-C to the transferee or mortgagee, and in the event of such transfer, Tenant shall look solely to such transferee or mortgagee for the return of the L-C Security Deposit and/or the L-C, provided such transferee agrees in writing to be liable to Tenant for the return of the L-C.  Landlord shall pay all costs and fees, if any, charged by the issuing bank to transfer the L-C.  Tenant shall, within five (5) days of request by Landlord, execute such further instruments or assurances as Landlord may reasonably deem necessary to evidence or confirm Landlord’s transfer or assignment of the L-C Security Deposit and/or the L-C to such transferee or mortgagee.  If Tenant is not then in default under this Lease, the L-C Security Deposit and/or the L-C, or any balance thereof, shall be returned to Tenant within forty-five (45) days following the expiration of the Lease Term.

ARTICLE 22

TELECOMMUNICATIONS EQUIPMENT

At any time during the Lease Term, subject to the TCCs of this Article 22 and Article 8 of this Lease, Tenant may install, at Tenant’s sole cost and expense, but without the payment of any Rent or a license or similar fee or charge, a satellite or microwave dish or other communications, HVAC or other equipment servicing the business conducted by Tenant from within the Premises (all such equipment, including non-telecommunication equipment is, for the sake of convenience, defined collectively as the “Telecommunications Equipment”) upon the roof of the Building.  The physical appearance and the size of the Telecommunications Equipment shall be subject to Landlord’s reasonable approval, the location of any such installation of the Telecommunications Equipment shall be designated by Tenant subject to Landlord’s reasonable approval and Landlord may require Tenant to install screening around such Telecommunications Equipment, at Tenant’s sole cost and expense, as reasonably designated by Landlord.  Tenant shall maintain such Telecommunications Equipment, at Tenant’s sole cost and expense.  In the event Tenant elects to exercise its right to install the Telecommunication Equipment, then Tenant shall give Landlord prior notice thereof.  Tenant shall remove such Telecommunications Equipment upon the expiration or earlier termination of this Lease and shall restore such area to the condition the same existed prior to the installation of such Telecommunications Equipment.  Such Telecommunications Equipment shall be installed pursuant to plans and specifications approved by Landlord, which approval will not be unreasonably withheld.  Such Telecommunications Equipment shall, in all instances, comply with applicable governmental laws, codes, rules and regulations.  The rights contained in this Article 22 shall be personal to the Original Tenant and its Affiliates and may only be exercised by the Original Tenant or an Affiliate (and not any assignee, sublessee or other transferee of the Original Tenant’s interest in this Lease) if the Original Tenant and/or an Affiliate is in occupancy of at least sixty percent (60%) of the then-existing Premises.  Landlord shall reserve the concurrent right to use the roof for its own use and for third-party use for installation of satellite dish and antenna devices similar to Tenant’s Telecommunications Equipment (collectively, the “Landlord TCE”), provided such Landlord TCE shall not interfere with Tenant’s operations on the roof of the Building, and provided Landlord maintains, restores and repairs the Building rooftop space associated with such Landlord TCE.  To the extent Landlord elects to install Landlord TCE on the Building rooftop, Landlord shall be responsible for the maintenance, repair and restoration of such Landlord TCE.  Landlord shall be responsible for (and shall make all necessary repairs and replacements for) any damage to Tenant’s Telecommunications Equipment

52

due to the actions or omissions of Landlord or Landlord Parties (or any third party to whom Landlord has granted roof access rights).  Tenant shall be responsible for (and shall make all necessary repairs and replacements for) any damage to the Landlord TCE due to the negligence or willful misconduct of Tenant.

ARTICLE 23

SIGNS

23.1                           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.  Except as expressly permitted pursuant to Section 23.2, below, Tenant may not install any signs on the exterior or roof of the Project or the Common Areas.  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.

23.2                           Tenant’s Signage.  Tenant shall be entitled to install the following signage in connection with Tenant’s lease of the Premises (collectively, the “Tenant’s Signage”):

(i)                     One (1) building sign identifying Tenant’s name and logo located at the top of the Building (the “Building Top Sign”), as more particularly identified on Exhibit A-2 attached hereto; and

(ii)                  Non-exclusive signage on a pro-rata portion (vis-á-vis the rentable square footage of the Premises as compared to the rentable square footage of the Building) of the monument located adjacent to the entrance of the Building (the “Building Monument Sign”).  Tenant hereby acknowledges and agrees that Landlord may, at Landlord’s sole cost and expense, place a standard “owned and managed” sign on such Project Monument Sign, provided that such “owned and managed” sign shall not be larger than Tenant’s sign.  Landlord may also, at Landlord’s sole cost and expense, install a small sign indicating its ownership and management of the Building in the interior of the Building lobby in a location and of a size reasonably approved by Tenant.

To the extent that Tenant leases all of the 10421 Building and the 10445 Building, Tenant shall be permitted to install, and the term “Tenant’s Signage” shall be revised to mean, all signage that is legally permitted in the Project; provided, however, Landlord shall retain the right for limited identification signage as identified in item (ii) above.

23.2.1                  Specifications and Permits.  Tenant’s Signage shall set forth Tenant’s name and logo as determined by Tenant in its sole discretion; provided, however, in no event shall Tenant’s Signage include an “Objectionable Name,” as that term is defined in Section 23.2.2, of this Lease.  The graphics, materials, color, design, lettering, lighting, size,

53

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 and Landlord’s Building standard signage program.  For purposes of this Section 23.2.1, the reference to “name” shall mean name and/or logo.  In addition, Tenant’s Signage shall be subject to Tenant’s receipt of all required governmental permits and approvals and shall be subject to all Applicable Law and to any covenants, conditions and restrictions affecting the Project.  Landlord shall use commercially reasonable efforts to assist Tenant in obtaining all necessary governmental permits and approvals for Tenant’s Signage.  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.

23.2.2                  Objectionable Name.  To the extent Original Tenant desires to change the name and/or logo set forth on Tenant’s Signage, such name and/or logo shall not have a name 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 name “Favrille, Inc.,” or any reasonable derivation thereof, shall not be deemed an Objectionable Name.

23.2.3                  Termination of Right to Tenant’s Signage.  The rights contained in this Section 23.2 shall be personal to the Original Tenant and may only be exercised by the Original Tenant (and not any assignee, sublessee or transferee of the Original Tenant’s interest in this Lease) if the Original Tenant is in occupancy of no less than sixty percent (60%) of the then existing Premises.

23.2.4                  Cost and Maintenance.  The costs of the actual signs comprising Tenant’s Signage and the installation, design, construction, and any and all other costs associated with Tenant’s Signage, including, without limitation, utility charges and hook-up fees, permits, and maintenance and repairs, shall be the sole responsibility of Tenant; provided, however, up to a total of Ten Thousand and No/100 Dollars ($10,000.00) of the actual costs of such initial installation, design and construction shall be subject to reimbursement from the Improvement Allowance pursuant to Section 2.2.1 of the Tenant Work Letter.  Should Tenant’s Signage require repairs and/or maintenance, as determined in Landlord’s reasonable judgment, Landlord shall have the right to provide notice thereof to Tenant and Tenant shall cause such repairs and/or maintenance to be performed within thirty (30) days after receipt of such notice from Landlord, at Tenant’s sole cost and expense; provided, however, if such repairs and/or maintenance are reasonably expected to require longer than thirty (30) days to perform, Tenant shall commence such repairs and/or maintenance within such thirty (30) day period and shall diligently prosecute such repairs and maintenance to completion.  Should Tenant fail to perform such repairs and/or maintenance within the periods described in the immediately preceding sentence, Landlord shall, upon the delivery of an additional ten (10) business days’ prior written notice, have the right to cause such work to be performed and to charge Tenant as Additional Rent for the cost (including

54

a percentage of the cost thereof sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and/or maintenance) of such work.  Upon the expiration or earlier termination of this Lease, Tenant shall, at Tenant’s sole cost and expense, cause Tenant’s Signage to be removed and shall cause the areas in which such Tenant’s Signage was located to be restored to the condition existing immediately prior to the placement of such Tenant’s Signage except for ordinary wear and tear.  If Tenant fails to timely remove such Tenant’s Signage or to restore the areas in which such Tenant’s Signage was located, as provided in the immediately preceding sentence, then Landlord may perform such work, and all costs incurred by Landlord in so performing (including a percentage of the cost thereof sufficient to reimburse Landlord for all overhead, general conditions, fees and other costs or expenses arising from Landlord’s involvement with such repairs and/or maintenance) shall be reimbursed by Tenant to Landlord within thirty (30) days after Tenant’s receipt of an invoice therefor.  The TCCs of this Section 23.2.4 shall survive the expiration or earlier termination of this Lease.

ARTICLE 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 (collectively, “Applicable Laws”).  At its sole cost and expense, Tenant shall promptly comply with all such Applicable Laws which relate to (i) Tenant’s use of a portion of the Premises for non-general office use, (ii) the Alterations or Tenant Improvements in the Premises, or (iii) the Building Systems, and (iv) the Building Structure, but, as to the Building Structure, only to the extent such obligations are triggered by Tenant’s Alterations, the Tenant Improvements, the Tenant’s modification of the Building Structure or use of a portion of the Premises for non-general office use.  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 which are applicable to Tenant’s business.  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 (a) the Building Structure, and (b) the exterior Project components, provided that compliance with such Applicable Laws is not the responsibility of Tenant under this Lease, and provided further that Landlord’s failure to comply therewith would (1) prohibit Tenant from obtaining or maintaining a certificate of occupancy for the Premises, (2) unreasonably and materially affect the safety of Tenant’s employees or create a significant health hazard for Tenant’s employees, (3) invalidate Tenant’s cGMP compliance status in, or materially and unreasonably prevent, hinder, or interrupt Tenant’s ability to continually function under cGMP conditions under the applicable laws and regulations of, California and the United States, and under the applicable statutes for any foreign regulatory body, including but not limited to, Canada, Europe and Asia, or (4) materially increase the costs incurred by Tenant to comply with its maintenance obligations under the TCCs of this Lease.  Landlord shall be

55

permitted to include in Operating Expenses any costs or expenses incurred by Landlord under this Article 24 to the extent consistent with the terms of Section 4.2.4, above.

ARTICLE 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 said amount is due, then Tenant shall pay to Landlord a late charge equal to five percent (5%) of the overdue amount plus any 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.

ARTICLE 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 Article 10 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.

56

ARTICLE 27

ENTRY BY LANDLORD

Landlord reserves the right at all reasonable times (during Building Hours with respect to items (i) and (ii) below) and upon at least twenty-four (24) hours prior notice to Tenant (except in the case of an emergency) and at all times (except in the case of an emergency) accompanied by an authorized representative of Tenant and subject to Tenant’s reasonable rules and regulations, to enter the Premises 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 nine (9) months of the Lease Term, to prospective tenants; (iii) post notices of nonresponsibility; or (iv) alter, improve or repair the Premises or the Building as permitted or required by the terms of this Lease, or for structural alterations, repairs or improvements to the Building Structure.  Notwithstanding anything to the contrary contained in this Article 27, Landlord may enter the Premises at any time to (A) perform services required of Landlord under this Lease after reasonable notice to Tenant; (B) take possession due to any breach of this Lease in the manner provided herein; and (C) perform any covenants of Tenant which Tenant fails to perform (after any applicable notice and cure periods).  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; provided, however, except for (i) emergencies, (ii) repairs, alterations, improvements or additions required by governmental or quasi-governmental authorities or court order or decree, or (iii) repairs which are the obligation of Tenant hereunder, any such entry shall be performed in a manner so as not to unreasonably interfere with Tenant’s use of the Premises and shall be performed after normal business hours if reasonably practical.  With respect to items (ii) and (iii) above, Landlord shall use commercially reasonable efforts to not materially interfere with Tenant’s use of, or access to, the Premises.  Except as otherwise set forth in Section 6.4, Tenant hereby waives any claims for damages or for any injuries or inconvenience to or interference with Tenant’s business, lost profits, any loss of occupancy or quiet enjoyment of the Premises, and any other loss occasioned thereby.  For each of the above purposes, Landlord shall at all times have a key with which to unlock all the doors in the Premises, excluding Tenant’s vaults, safes and special security areas designated in advance by Tenant.  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.  No provision of this Lease shall be construed as obligating Landlord to perform any repairs, alterations or decorations except as otherwise expressly agreed to be performed by Landlord herein.

ARTICLE 28

TENANT PARKING

Tenant shall be entitled to utilize, without charge, commencing on the Lease Commencement Date, the amount of parking spaces set forth in Section 9 of the Summary, on a monthly basis throughout the Lease Term, which parking spaces shall pertain to the Project parking facility.  Notwithstanding the foregoing, Tenant shall be responsible for the full amount

57

of any taxes imposed by any governmental authority in connection with the renting of such parking spaces by Tenant or the use of the parking facility by Tenant.  Tenant’s continued right to use the parking spaces is conditioned upon Tenant abiding by all rules and regulations which are prescribed from time to time for the orderly operation and use of the parking facility where the parking spaces are located, including any sticker or other identification system established by Landlord, Tenant’s cooperation in seeing that Tenant’s employees and visitors also comply with such rules and regulations and Tenant not being in default under this Lease.  Subject to Landlord’s continued satisfaction of its obligation to provide Tenant the number of parking spaces required by the TCCs of this Lease, Landlord specifically reserves the right to change the size, configuration, design, layout and all other aspects of the Project parking facility at any time and Tenant acknowledges and agrees that Landlord may, without incurring any liability to Tenant and without any abatement of Rent under this Lease, from time to time, close-off or restrict access to the Project parking facility for purposes of permitting or facilitating any such construction, alteration or improvements.  Landlord may delegate its responsibilities hereunder to a parking operator in which case such parking operator shall have all the rights of control attributed hereby to the Landlord.  The parking spaces rented by Tenant pursuant to this Article 28 are provided to Tenant solely for use by Tenant’s own personnel and such spaces may not be transferred, assigned, subleased or otherwise alienated by Tenant without Landlord’s prior approval; provided, however, Landlord shall be deemed to have granted such approval with regard to Non-Transfers and Transfers approved pursuant to the TCCs of Article 14.  Tenant may validate visitor parking by such method or methods as the Landlord may establish, at the validation rate from time to time generally applicable to visitor parking.

ARTICLE 29

58

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) 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) days following the request therefor.

29.5                           Transfer of Landlord’s Interest.  Tenant acknowledges that Landlord has the right to transfer all or any portion of its interest in the Project or Building and in this Lease, and Tenant agrees that in the event of any such transfer, Landlord shall automatically be released from all liability under this Lease accruing after the date such transfer and Tenant agrees to look solely to such transferee for the performance of Landlord’s obligations hereunder after the date of transfer and such transferee shall be deemed to have fully assumed and be liable for all obligations of this Lease to be performed by Landlord, including the return of any Security Deposit, and Tenant shall attorn to such transferee.  Tenant further acknowledges that Landlord may assign its interest in this Lease to a mortgage lender as additional security and agrees that such an assignment shall not release Landlord from its obligations hereunder and that Tenant shall continue to look to Landlord for the performance of its obligations hereunder.

29.6                           Prohibition Against Recording.  Except as provided in Section 29.4 of this Lease, neither this Lease, nor any memorandum, affidavit or other writing with respect thereto, shall be recorded by Tenant or by anyone acting through, under or on behalf of Tenant.

29.10                     Time of Essence.  Time is of the essence with respect to the performance of every provision of this Lease in which time of performance is a factor.

29.11                     Partial Invalidity.  If any term, provision or condition contained in this Lease shall, to any extent, be invalid or unenforceable, the remainder of this Lease, or the application of such term, provision or condition to persons or circumstances other than those with respect to which it is invalid or unenforceable, shall not be affected thereby, and each and every other term,

59

provision and condition of this Lease shall be valid and enforceable to the fullest extent possible permitted by law.

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 Building (as such value is determined by Landlord), following the payment of any outstanding liens and/or mortgages in connection with the Project; provided, however, in no event shall the foregoing be deemed to limit any obligation Landlord may have pursuant to the TCCs of this Lease to return or pay the Improvement Allowance as set forth in the Tenant Work Letter, or to Tenant the Security Deposit and/or the L-C Security Deposit.  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 consequential damages arising from any 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.

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.  Subject to the TCC’s of Section 1.3 of this Lease, Landlord reserves the absolute right to effect such other tenancies in the Project as Landlord in the exercise

60

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, inability to obtain services, labor, or materials or reasonable substitutes therefor, 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 and except as to Tenant’s obligations under Articles 5 and 24 of 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.

29.17                     Waiver of Redemption by Tenant.  Tenant hereby waives, for Tenant and for all those claiming under Tenant, any and all rights now or hereafter existing to redeem by order or judgment of any court or by any legal process or writ, Tenant’s right of occupancy of the Premises after any termination of this Lease.

62

DAMAGE, OR ANY EMERGENCY OR STATUTORY REMEDY.  IN THE EVENT LANDLORD COMMENCES ANY SUMMARY PROCEEDINGS OR ACTION FOR NONPAYMENT OF BASE RENT OR ADDITIONAL RENT, TENANT SHALL NOT INTERPOSE ANY COUNTERCLAIM OF ANY NATURE OR DESCRIPTION (UNLESS SUCH COUNTERCLAIM SHALL BE MANDATORY) IN ANY SUCH PROCEEDING OR ACTION, BUT SHALL BE RELEGATED TO AN INDEPENDENT ACTION AT LAW.

29.23                     Submission of Lease.  Submission of this instrument for examination or signature by Tenant does not constitute a reservation of, option for or option to lease, and it is not effective as a lease or otherwise until execution and delivery by both Landlord and Tenant.

29.24                     Brokers.  Landlord and Tenant hereby warrant to each other that they have had no dealings with any real estate broker or agent in connection with the negotiation of this Lease, excepting only the real estate brokers or agents specified in Section 12 of the Summary (the “Brokers”), and that they know of no other real estate broker or agent who is entitled to a commission in connection with this Lease.  Each party agrees to indemnify and defend the other party against and hold the other party harmless from any and all claims, demands, losses, liabilities, lawsuits, judgments, costs and expenses (including without limitation reasonable attorneys’ fees) with respect to any leasing commission or equivalent compensation alleged to be owing on account of any dealings with any real estate broker or agent, other than the Brokers, occurring by, through, or under the indemnifying party.

29.25                     Independent Covenants.  This Lease shall be construed as though the covenants herein between Landlord and Tenant are independent and not dependent and Tenant hereby expressly waives the benefit of any statute to the contrary and agrees that if Landlord fails to perform its obligations set forth herein, Tenant shall not be entitled to make any repairs or perform any acts hereunder at Landlord’s expense or to any setoff of the Rent or other amounts owing hereunder against Landlord, except as expressly set forth in this Lease.

29.29                     Transportation Management.  Tenant shall fully comply with all present or future governmental programs intended to manage parking, transportation or traffic in and around the Building, and in connection therewith, Tenant shall take responsible action for the transportation planning and management of all employees located at the Premises by working directly with Landlord, any governmental transportation management organization or any other transportation-related committees or entities.

68

Tenant’s sole discretion.  Tenant hereby waives any and all rent offsets or claims of constructive eviction which may arise in connection with such construction.
