 Exhibit 10.1 

THIRD AMENDMENT 
 TO LOAN AND
SECURITY AGREEMENT 
 This Third Amendment to Loan and Security Agreement (this “Amendment”) is entered into as of
September 30, 2013, by and between COMERICA BANK (“Bank”) and CARBONITE, INC, a Delaware corporation (“Borrower”). 

RECITALS 
 Borrower and
Bank are parties to that certain Loan and Security Agreement dated as of May 11, 2011, as amended, modified, supplemented, extended or restated from time to time, including by that certain First Amendment to Loan and Security Agreement dated as
of August 30, 2012 and that certain Second Amendment to Loan and Security Agreement dated as of August 30, 2013 (collectively, the “Agreement”). The parties desire to amend the Agreement in accordance with the terms of this
Amendment. 
 NOW, THEREFORE, for good and valuable consideration, the receipt of which is hereby acknowledged, the parties agree as
follows: 
 1. Exhibit A to the Agreement is hereby amended by amending and restating the following defined term to read as follows:

 “Revolving Maturity Date” means September 30, 2014. 

2. No course of dealing on the part of Bank or its officers, nor any failure or delay in the exercise of any right by Bank, shall operate as a
waiver thereof, and any single or partial exercise of any such right shall not preclude any later exercise of any such right. Bank’s failure at any time to require strict performance by Borrower of any provision shall not affect any right of
Bank thereafter to demand strict compliance and performance. Any suspension or waiver of a right must be in writing signed by an officer of Bank. 

3. Unless otherwise defined, all initially capitalized terms in this Amendment shall be as defined in the Agreement (as amended by this
Amendment). The Agreement, as amended hereby, shall be and remain in full force and effect in accordance with its terms and hereby is ratified and confirmed in all respects. Except as expressly set forth herein, the execution, delivery, and
performance of this Amendment shall not operate as a waiver of, or as an amendment of, any right, power, or remedy of Bank under the Agreement, as in effect prior to the date hereof. Borrower ratifies and reaffirms the continuing effectiveness of
all promissory notes, guaranties, security agreements, mortgages, deeds of trust, environmental agreements, and all other instruments, documents and agreements entered into in connection with the Agreement. Borrower hereby further affirms its
absolute and unconditional promise to pay to Bank the Advances, all other Credit Extensions and all other amounts due under the Letters of Credit and the other Loan Documents (including, without limitation, the Obligations), at the times and in the
amounts provided for therein. Borrower confirms and agrees that the obligations of Borrower to Bank under the Agreement as supplemented hereby are secured by and entitled to the benefits of the Loan Documents. The parties agree that this Amendment
shall be deemed to be one of the Loan Documents under the Agreement. Nothing in this Amendment shall constitute a satisfaction of any of Borrower’s Obligations. 

4. In order to induce Bank to enter into this Amendment, Borrower hereby represents and warrants to Bank as follows: 

4.1 The representations and warranties contained in the Agreement and the other Loan Documents were true and correct in all material respects
when made and continue to be true and correct in all material respects as of the date of this Amendment. 
 4.2 Both before and immediately
after giving effect to this Amendment and the other transactions contemplated hereby, no Event of Default, or other event or circumstance that with the giving of notice or the passage of time could become an Event of Default, has occurred and is
continuing. 

  
 -1- 

 4.3 The execution, delivery, and performance by Borrower of this Amendment and the other
documents, instruments and agreements to which Borrower is a party delivered or to be delivered to Bank in connection herewith (i) are within the corporate powers of Borrower and have been duly authorized by all necessary corporate action on
the part of Borrower, (ii) do not require any governmental or third party consents, except those which have been duly obtained and are in full force and effect, (iii) do not and will not conflict with any requirement of law,
Borrower’s or any Guarantor’s articles or certificate of incorporation, bylaws, operating agreement, partnership agreement, minutes or resolutions, (iv) after giving effect to this Amendment, do not result in any breach of or
constitute a default under any agreement or instrument to which Borrower, any Guarantor or any of their respective Subsidiaries is a party or by which they or any of their respective properties are bound, and (v) do not result in or require the
creation or imposition of any mortgage, deed of trust, pledge, lien, security interest or other charge or encumbrance of any nature upon any of the assets or properties of Borrower or any Guarantor, other than those in favor of Bank. 

4.4 This Amendment and the other instruments and agreements delivered or to be delivered to Bank in connection herewith have been duly executed
and delivered by Borrower and constitutes the legal, valid, and binding obligation of Borrower, enforceable against Borrower in accordance with their respective terms, except to the extent that (i) enforcement may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or similar laws of general application affecting the rights and remedies of creditors, (ii) enforcement maybe subject to general principles of equity, and (iii) the availability of the
remedies of specific performance and injunctive relief may be subject to the discretion of the court before which any proceedings for such remedies may be brought. 

4.5 Borrower does not have any right of offset, defense, counterclaim, dispute or disagreement of any kind or nature whatsoever with respect to
any of its liabilities, obligations or indebtedness arising under or in connection with any Loan Document. 
 5. As a condition to the
effectiveness of this Amendment, Bank shall have received, in form and substance satisfactory to Bank, the following: 
 (a) this Amendment,
duly executed by Borrower; 
 (b) an Affirmation of Guaranties and Security Agreement, duly executed by each Guarantor; 

(c) corporate resolutions and incumbency certifications, duly executed by Borrower and each Guarantor; 

(d) a fully-earned and non-refundable amendment fee in the amount of $ 15,000, which may be debited from any of Borrower’s accounts with
Bank; 
 (e) an amount equal to all Bank Expenses incurred through the date of this Amendment, which amounts maybe debited from any of
Borrower’s accounts with Bank; and 
 (f) such other documents, instruments and certificates and completion of such other matters, as
Bank may reasonably deem necessary or appropriate. 
 6. This Amendment may be executed in two or more counterparts, each of which shall be
deemed an original, but all of which together shall constitute one instrument.

 2. PREMISES 

2.1. Premises. Landlord hereby leases to Tenant and Tenant hereby leases from Landlord for Tenant’s own use in the conduct of
Tenant’s business and not for purposes of speculating in real estate, for the Term and upon the terms and subject to the conditions of this Lease, that certain interior space described in Article 1 as the “Premises”,
reserving and excepting to Landlord (a) such access as may be required (including but not limited to elevator access) by Landlord to the Building roof and heating, ventilating, air conditioning, ducting, cabling systems, and other Building
Systems, (b) the right to place additional vertical penetrations behind the walls of the Premises as needed for heating, ventilating, air conditioning, ducting, cabling, and other Building Systems, and (c) the right to access the Premises
for the management of the Property and fulfillment of Landlord’s duties and obligations under this Lease. Tenant’s lease of the Premises, together with the appurtenant right to use the Common Areas as described in Paragraph 2.2 below,
shall be subject to the continuing compliance by Tenant with (i) all the terms and conditions of this Lease, (ii) all Applicable Laws governing the use of the Premises and the Property, (iii) all private restrictions, easements and
other matters now of public record respecting the use of the Premises and Property, and (iv) all reasonable rules and regulations from time to time established by Landlord, provided, however, that Landlord’s exercise of each such
exceptions and reservations shall be subject to the terms and conditions of this Lease and shall not unreasonably interfere with Tenant’s rights under this Lease. The building in which the Premises is located is sometimes referred to herein as
the “Building”. The land upon which the Building is located is sometimes referred to herein as the “Property.” 

2.2. Common Area. Landlord hereby grants to Tenant and its employees, agents, contractors and invitees (collectively,
“Tenant’s Agents”) a non-exclusive license to use the public areas within the Building and the public areas, sidewalks, driveways, parking areas and other public amenities on the Property (the “Common
Area”) during the Term. Tenant’s rights to the Common Area shall be subject to the Rules and Regulations described in Section 23.1 and to Landlord’s reserved rights described in Article 16. 

2.3. Parking. Throughout the Term of this Lease, and any extensions thereof, Tenant shall have the right to use the number of parking
spaces specified in Article 1, at no additional cost to Tenant. Tenant’s license shall not be assigned, sublet or otherwise transferred separately from the Premises. Tenant agrees that neither Tenant nor Tenant’s Agents shall use parking
spaces in excess of the number of spaces allocated to Tenant or in areas designated for other uses. Landlord shall have the right, at Landlord’s sole discretion, to specifically designate the location of Tenant’s parking spaces within the
parking areas of the Common Area, and Tenant’s designated parking spaces (if any) may be relocated by Landlord from time to time upon thirty (30) days’ prior written notice; provided, however, that to the full extent practicable
Tenant’s parking spaces shall be located adjacent to one another in one distinct area in the parking lot or in no more than two (2) distinct areas in the parking lot. Tenant shall not at any time park, or permit the parking of the trucks
or vehicles of Tenant or Tenant’s Agents in any portion of the Common Area not designated by Landlord for such use by Tenant. Tenant shall not park nor permit to be parked any inoperative vehicles or store any materials or equipment on any
portion of the parking area or other areas of the Common Area. Tenant agrees to assume responsibility for compliance by Tenant’s Agents with the parking provisions contained in this Section. Tenant hereby authorizes Landlord at Tenant’s
expense to attach violation stickers or notices to vehicles not parked in compliance with this Section and to tow away any such vehicles if such violation is not cured following attachment of such stickers or notices. In addition, Landlord may set a
specific section of the parking area aside for visitor or specially assigned parking for the Property. 

  
 4 

 2.4. Fitness Center. Tenant’s employees may use the existing fitness center
facilities located in the Building (“Fitness Center”) on a non-exclusive basis at no charge during the Term, subject to the Rules and Regulations, so long as Landlord operates the Fitness Center as part of the Common Area. 

2.5. Conference Center. Subject to Landlord’s reserved rights described in Article 16, Tenant may utilize the First Floor
conference center subject to the Rules and Regulations for Landlord’s standard charge, so long as Landlord operates the Conference Center as part of the Common Area.  

2.6. Fifth Floor Right of First Offer. Tenant shall have an ongoing Right of First Offer (“ROFO”) to lease space that may
come available on the Fifth Floor of the Building, which in total contains approximately 20,116 rentable square feet (the space that comes available, the “ROFO Premises”), based on and subject to the following conditions and terms: 

 (a) The ROFO shall be subject to the existing rights of any Tenants leasing the ROFO Premises now or at any time in the
future in accordance with the terms of this Section. The ROFO shall not limit Landlord’s ability to extend or renew the leases of those tenants now or at any time in the future in possession of any ROFO Premises. 

(b) The ROFO Premises will be incorporated into this Lease except that (a) the economic terms shall be as set forth in the ROFO
Notice or as otherwise agreed in writing by the parties, (b) Tenant’s Pro Rata Share shall be increased to reflect the addition of the ROFO Premises, and (c) the number of parking spaces shall be adjusted to reflect the addition of
the ROFO Premises, and (d) notwithstanding any lease term proposed by Landlord, the term applicable to the ROFO Premises will be the same as the Term of the Lease. Unless specified otherwise in the ROFO Notice, the ROFO Premises shall be leased
on an “as-is” basis and Landlord shall have no obligation to improve the ROFO Premises or grant Tenant any improvement allowance for the ROFO Premises unless Landlord intends to offer (or offers) any such concessions in the ROFO Notice.

 (c) The ROFO Premises must be accepted by and leased to Tenant in its entirety. 

(d) Anything herein to the contrary notwithstanding, Tenant shall have no rights with respect to the ROFO Premises if: 

(i) an Event of Default exists and is continuing, either on the date Landlord delivers the ROFO Notice to Tenant or when the ROFO Premises
are to be incorporated into this Lease; 
 (ii) Tenant has assigned or sublet any portion of the Premises (other than pursuant to a
Permitted Transfer) as of the date Landlord would otherwise deliver the ROFO Notice; 
 (iii) Tenant or a Permitted Transferee is not
occupying the Premises on the date Landlord would otherwise deliver the ROFO Notice; or 

  
 5 

 (iv) the ROFO Premises is not intended for the exclusive use of Tenant or a Permitted
Transferee. 
 Tenant’s sole rights as to the ROFO Premises shall be as follows: 

(e) Prior to offering the ROFO Premises for lease to any third party, Landlord shall deliver a written notice (the “ROFO
Notice”) to Tenant setting forth the terms upon which Landlord proposes to lease the ROFO Premises. 
 (f) Tenant shall
have ten (10) business days in which to accept the terms contained in the ROFO Notice or otherwise to reach agreement to incorporate such ROFO Premises into the Lease. If Landlord and Tenant do not so reach agreement within such period and
thereafter incorporate the applicable ROFO Premises into the Lease, Landlord shall be free to market the ROFO Premises to third parties; provided that Landlord shall not enter into an agreement to lease the ROFO Premises on terms that are materially
more favorable to the third party than those set forth in the ROFO Notice without submitting such terms to Tenant in a new ROFO Notice. For purposes hereof, the terms offered to a third party shall be deemed to be materially more favorable than
those set forth in the ROFO Notice if there is more than a ten percent (10%) reduction in the effective cost per square foot of Rentable Area, considering all of the applicable economic terms, including, without limitation, the length of term,
the net rent, and any expense or other financial escalation. If the terms agreed to with a third party are materially more favorable than those set forth in the ROFO Notice, then Landlord shall so inform Tenant with a new ROFO Notice and Tenant
shall have the right, for a period of ten (10) business days, to accept such terms in writing and thereafter promptly to enter into an amendment of the Lease incorporating the ROFO Premises. In the event Landlord and Tenant do not enter into
such amendment within the period specified, Landlord shall be free to enter into a lease with a third party on terms not materially more favorable to the third party than those offered to Tenant. 

(g) If Landlord fails to enter into a lease agreement with a third party with respect to the ROFO Premises within one hundred eighty
(180) days after the date of the ROFO Notice, Tenant’s ROFO rights shall be reinstated, and Landlord shall again be obligated to comply with the provisions of this Section. 

2.7. One-Time Eighth & Ninth Floor Right of First Offer. Upon the event of Walmart.com vacating or providing notice that it
will vacate the Eighth Floor and the Ninth Floor of the Building, each of which contains approximately 20,116 rentable square feet (“Eighth & Ninth Floor ROFO Premises”, respectively), Tenant shall have a
“One-Time ROFO” to lease both floors, unless the Landlord agrees to lease the floors individually in its sole discretion. If Tenant declines to exercise its right to lease both the Eighth and Ninth Floors under said
One-Time Eighth & Ninth Floor ROFO, said ROFO shall terminate. Upon the event of Walmart.com vacating or providing notice that it will vacate either the Eighth Floor or the Ninth Floor, Tenant shall have a “One-Time
ROFO” to lease such floor as it is vacated or being vacated by Walmart.com. If Tenant declines to exercise its right to lease the floor covered by such ROFO, said ROFO as to such floor shall terminate. The One-Time ROFO shall be based on
and subject to the conditions and terms for the ROFO and ROFO Premises set forth in Section 2.6, except that Section 2.6.g shall not apply. 

3. ACCEPTANCE 
 Landlord
represents and warrants to Tenant that on the Commencement Date the Building Structure and the Building Systems are in good operating condition and repair and 

  
 6 

 
that the Tenant Improvement Work is in compliance with all Applicable Laws, including without limitation all applicable building codes. Landlord, at its expense and within a reasonable time after
notice thereof, shall correct and/or obtain as-built permits for any Tenant Improvement Work determined not to have been done in compliance with all Applicable Laws. Subject to the foregoing, as of the Commencement Date, Tenant accepts the Premises
in their existing “as-is” condition, and Landlord shall have no obligation for construction work or improvements on or to the Premises, the Building or the Common Area, except for the Tenant Improvement Work pursuant to Section 9.1
and Exhibit E. Prior to entering into this Lease, Tenant has made a thorough and independent examination of the Premises and all matters related to Tenant’s decision to enter into this Lease. Tenant is thoroughly familiar with all aspects of
the Premises and is satisfied that it is in an acceptable condition and meet Tenant’s needs. Except as set forth above or elsewhere in this Lease, Tenant does not rely on, and Landlord does not make, any express or implied representations or
warranties as to any matters including, without limitation, (a) the existence, quality, adequacy or availability of utilities serving the Property, (b) the use, habitability, merchantability, fitness or suitability of the Premises for
Tenant’s intended use, (c) the likelihood of deriving business from Tenant’s location or the economic feasibility of Tenant’s business, (d) Hazardous Materials in the Premises, or on, in under or around the Property,
(e) zoning, entitlements or any laws, ordinances or regulations which may apply to Tenant’s use of the Premises or business operations, or (f) any other matter. Tenant has satisfied itself as to such suitability and other pertinent
matters by Tenant’s own inquiries and tests into all matters relevant in determining whether to enter into this Lease. Tenant shall, by entering into and occupying the Premises, be deemed to have accepted the Premises and to have acknowledged
that the same are in good order, condition and repair, except as set forth in this Lease. Upon the Commencement Date, Tenant shall execute and deliver to Landlord the Acceptance Form attached hereto as Exhibit D. 

4. TERM 
 4.1.
Term. The Premises are leased for a term (the “Term”) commencing on the Commencement Date and expiring upon the Expiration Date, or such earlier date on which this Lease terminates pursuant to its terms. The date upon
which this Lease actually terminates, whether by expiration of the Term or earlier termination pursuant to the terms of this Lease, is sometimes referred to in this Lease as the “Termination Date”. Upon delivery of
possession, Landlord shall specify in a written notice to Tenant, substantially in the form of Exhibit B, the Commencement Date, Rent Commencement Date and Expiration Date of this Lease. Such notice shall be delivered promptly after
all of the information set forth in the notice has been determined; provided that Landlord’s failure to do so shall not in any way affect either party’s rights or obligations under this Lease. 

4.2. Failure to Deliver Possession. If for any reason Landlord cannot deliver possession of the Premises or any part thereof to Tenant
on or prior to the Scheduled Date for Delivery of the Premises, then the validity of this Lease and the obligations of Tenant under this Lease shall not be affected and Tenant shall have no claim against Landlord arising out of Landlord’s
failure to deliver possession of the Premises on the Scheduled Date for Delivery of the Premises. In the event Landlord has not delivered the Premises or any part thereof to Tenant within four (4) months after the Scheduled Date for Delivery of
the Premises, and provided that said failure to deliver is not due to action or inaction by Tenant, Tenant shall have the right to terminate this Lease by delivery to Landlord of a termination notice (the “Termination
Notice”) which shall be effective thirty (30) days after receipt by Landlord, unless within such 30-day period the Premises are delivered to Tenant. In the event Tenant elects to terminate this Lease, Tenant must deliver the
Termination Notice to Landlord prior to the date 

  
 7 

 
the Premises or the part thereof are delivered to Tenant. Upon such termination, neither party shall have any further obligation or liability to the other under this Lease with
respect to the Premises and Landlord shall return to Tenant all funds previously paid by Tenant to Landlord. 
 4.3. Early
Possession. Tenant shall have the right to take possession of the Premises before the Commencement Date for the sole purpose of performing improvements or installing furniture, equipment or other personal property. Such early possession shall be
subject to the terms and conditions of this Lease, provided that Tenant shall not be obligated to pay Rent (defined in Section 5.2.) except for the cost of services requested by Tenant (e.g. HVAC use).  

4.4. Renewal Option. Tenant shall have one (1) option (the “Renewal Option”) to extend the Term of the
Lease for the entire Premises then being leased to Tenant. The Renewal Option shall be for a five-year term (the “Renewal Term”). The Renewal Term shall commence on the day after the Expiration Date. The Renewal Option shall
be void if an Event of Default by Tenant exists, either at the time of exercise of the Renewal Option or the time of commencement of the Renewal Term. The Renewal Option must be exercised, if at all, by written notice from Tenant to Landlord given
not more than twelve (12) months and not less than nine (9) months prior to the expiration of the Term. The Renewal Term shall be upon the same terms and conditions as the original Term, except that (a) the Base Rent payable pursuant
to Section 4.1 with respect to the Renewal Term shall be equal to the Prevailing Market Rent as of the commencement of the Renewal Term, assuming that the first year of the Renewal Term will be the new Base Year, as determined pursuant to
Exhibit C; (b) the Base Rent shall escalate over the Renewal Term annually thereafter by the then prevailing increase rate (at least 3% per annum); (c) Tenant shall not be entitled to any tenant improvement
allowance during the Renewal Term,; and (d) from and after the exercise of the Renewal Option, (i) all references to “Expiration Date” shall be deemed to refer to the last day of the Renewal Term, and (ii) all references to
“Term” shall be deemed to include the Renewal Term. The Renewal Option is personal to Tenant and shall be inapplicable and null and void if Tenant assigns or sublets at least 50% of its interest under this Lease or if the Tenant is not
occupying at least 50% of the Premises. 
 5. RENT 

5.1. Base Rent. Commencing upon the Rent Commencement Date, and thereafter during the Term, Tenant shall pay to Landlord the monthly
Base Rent specified in Article 1 on or before the first day of each month, in advance, at the address specified for Landlord in Article 1, or at such other place as Landlord designates in writing, without any prior notice or demand and without any
deductions or setoff whatsoever (except as otherwise expressly provided in this Lease). Tenant shall pay the first month’s rent in advance, upon execution of this Lease. If the Rent Commencement Date occurs on a day other than the first day of
a calendar month, or the Termination Date occurs on a day other than the last day of a calendar month, then the Base Rent for such fractional month will be prorated on the basis of the actual number of days in such month. The Rentable Area of the
Premises shall be conclusively presumed to be as stated in Article 1, and shall not be subject to adjustment by either Landlord or Tenant during the Term. 

5.2. Additional Rent. All sums due from Tenant to Landlord under the terms of this Lease (other than Base Rent) shall be additional
rent (“Additional Rent”), including without limitation the charges for Tenant’s Pro Rata Share of Operating Expenses (described in Article 7) and all sums incurred by Landlord due to Tenant’s failure to perform its
obligations 

  
 8 

 
under this Lease. All Additional Rent that is payable to Landlord shall be paid at the time and place that Base Rent is paid. Landlord will have the same remedies for a default in the payment of
any Additional Rent as for a default in the payment of Base Rent. Together, Base Rent and Additional Rent are sometimes referred to in this Lease as “Rent”. 

5.3. Late Payment. Any unpaid Rent shall bear interest from the date due until paid at the lesser of the published “prime”
interest rate (that rate quoted by Wells Fargo Bank from time to time as its prime rate) plus six (6) percent (6%) per annum or the then maximum interest rate allowed by law (the “Interest Rate”). In addition,
Tenant recognizes that late payment of any Rent will result in administrative expense to Landlord, the extent of which expense is difficult and economically impracticable to determine. Therefore, Tenant agrees that if Tenant fails to pay any Rent
within five (5) days after its due date, an additional late charge of five percent (5%) of the sums so overdue shall become immediately due and payable, provided, however, that such late charge shall not be assessed upon Tenant’s
first (1st) late payment. Tenant agrees that the late payment charge is a reasonable estimate of the additional administrative costs and detriment that will be incurred by Landlord as a
result of such failure by Tenant. In the event of nonpayment of interest or late charges on overdue Rent, Landlord shall have, in addition to all other rights and remedies, the rights and remedies provided in this Lease and by law for nonpayment of
Rent. 
 5.4. Security Deposit. Concurrently with the execution of this Lease, Tenant shall deliver to Landlord the cash payment to
fulfill the Security Deposit requirement described in Article 1. The Security Deposit shall be held by Landlord as security for the faithful performance of this Lease by Tenant of all of the terms, covenants and conditions of this Lease. If there is
an Event of Default by Tenant with respect to any provisions of this Lease (including but not limited to the payment of Rent); if Tenant files a petition in bankruptcy, insolvency, reorganization, dissolution or liquidation under any law; makes an
assignment for the benefit of its creditors; consents to or acquiesces in the appointment of a receiver of itself or the Premises, or if a court of competent jurisdiction enters an order or judgment appointing a receiver of Tenant or the Premises;
or if a court of competent jurisdiction enters an order or judgment approving a petition filed against Tenant under any bankruptcy, insolvency or liquidation law, then in any such case Landlord may, without waiving any of Landlord’s other
rights or remedies under this Lease, apply the Security Deposit in whole or in part to remedy any failure by Tenant to pay any sums due under this Lease, to repair or maintain the Premises, to perform any other terms, covenants or conditions
contained in this Lease, to compensate Landlord for any loss or damages which Landlord may suffer as a result thereof, including without limitation any lost rent to which Landlord is entitled in the event the Lease terminates or is rejected as a
result of any of the foregoing. Should Landlord so apply any portion of the Security Deposit, Tenant shall replenish the Security Deposit to the original amount within fifteen (15) days after written demand by Landlord. Landlord shall not be
required to keep the Security Deposit separate from its general funds, and Tenant shall not be entitled to interest on the Security Deposit.

(i) wages, salaries, payroll taxes and other labor costs and employee benefits for all persons engaged in the operation, management,

 11 

 
Property, provided such persons are stationed at the Property and such costs do not exceed market rates for the operation of comparable projects in the vicinity of the Property; 

(j) management fees at commercially reasonable rates (whether or not Landlord employs a third party managing agent), but not exceeding
three percent (3%) of the base rent derived from the Property; 
 (k) fees, charges and other costs of all independent

 (l) license, permit and inspection fees; 

(m) the cost of supplies, tools, machines, materials and equipment used in operation and maintenance of the Common Area;

proceeds for the repair of damage to the Property or actually reimbursed by other third parties; 
 (ii) Financing and refinancing costs,
interest, principal, points and fees on debts or amortization on any mortgage or mortgages or any other debt instrument encumbering the Property; 

(iii) legal fees, leasing commissions, cash allowances, buy-out amounts, advertising expenses, promotional expenses, and other costs of a
similar nature incurred in the leasing of space at the Property; 
 (iv) ground rent or any other payments paid under any present or future
ground or overriding or underlying lease and/or grant affecting the Property and/or the Premises (other than payments which, independent of such lease, would constitute an Operating Expense hereunder); 

  
 12 

 (v) costs incurred due to a violation of the provisions of this Lease, any other agreement or
Applicable Law by Landlord; 
 (vi) costs arising from the presence of any Hazardous Materials or violation of Environmental Laws, except

(x) insurance deductibles or other costs of uninsured casualty to the extent Tenant’s pro-rata share exceeds Sixty Thousand Dollars
($60,000.00); or 
 (xi) costs to repair, maintain or replace the structural portions of the Building. 

7.3. Occupancy Assumption. If the Building is not at least 95% occupied during any calendar year or if Landlord is not supplying
services to at least 95% of the total Rentable Area of the Building at any time during a calendar year, Operating Expenses shall, at Landlord’s option, be determined as if the Building had been 95% occupied and Landlord had been supplying
services to 95% of the Rentable Area of the Building during that calendar year. If Tenant pays for its Pro Rata Share of Operating Expenses based on increases over a “Base Year” and Operating Expenses for a calendar year are determined as
provided in the prior sentence, Operating Expenses for the Base Year shall also be determined as if the Building had been 95% occupied and Landlord had been supplying services to 95% of the Rentable Area of the Building. The extrapolation of
Operating Expenses under this Section shall be performed by appropriately adjusting the cost of those components of Operating Expenses that are impacted by changes in the occupancy of the Building. 

7.4. Payment of Operating Expenses. Tenant shall pay to Landlord, as Additional Rent, Tenant’s Pro Rata Share of the amount, if
any, by which Operating Expenses for each calendar year during the Term exceed Operating Expenses for the Base Year (“Expense Excess”). Tenant shall pay one twelfth of Tenant’s Pro Rata Share of the Expense
Excess in advance, on or before the first day of each month in an amount estimated by Landlord as stated in a written notice to Tenant. Landlord may by written notice to Tenant revise such estimates from time to time and Tenant shall thereafter make
payments on the basis of such revised estimates. With reasonable promptness, typically within ninety (90) days after the expiration of each calendar year, Landlord will furnish Tenant with a statement (“Landlord’s Expense
Statement”) setting forth in reasonable detail the actual Operating Expenses for the prior calendar year and the amount of Tenant’s Pro Rata Share of the Expense Excess. If Tenant’s Pro Rata Share of the actual Expense Excess
for such year exceed the estimated amounts paid by Tenant for such year, Tenant shall pay to Landlord (whether or not this Lease has terminated) the difference between the amount of estimated Tenant’s Pro Rata Share of Expense Excess paid by
Tenant and the actual Tenant’s Pro Rata Share of Expense Excess within thirty (30) days after the receipt of Landlord’s Expense Statement. If the total amount 

  
 13 

 
paid by Tenant for any year exceeds the actual amount due from Tenant for that year, the excess shall be credited against the next installments of Additional Rent due from Tenant to Landlord, or,
if after the Termination Date, the excess shall first be credited against any unpaid Rent and any remaining excess shall be refunded promptly to Tenant. Notwithstanding the foregoing, Tenant shall have the right to audit Landlord’s books and
records with respect to any Landlord’s Expense Statement, provided Tenant delivers notice of such audit to Landlord within sixty (60) days after Tenant’s receipt of such Landlord’s Expense Statement. If Tenant’s audit
reveals that Landlord over-reported the actual Building Expenses for any calendar year by over ten percent (10%), then Landlord shall pay the cost of such audit, up to ten thousand dollars ($10,000). In any event, Landlord shall credit any
overpayment by Tenant to Operating Expenses next due, and Tenant shall reimburse Landlord for any underpayment within thirty (30) days following the completion of such audit. 

7.5. Proration. If either the Rent Commencement Date or the Termination Date occurs on a date other than the first or last day,
respectively, of a calendar year, Tenant’s Pro Rata Share of Expense Excess for the year in which the Rent Commencement Date or Termination Date occurs shall be prorated based on a 365-day year. 

7.6. Utility Costs. Landlord shall arrange for the following utilities furnished to or used at the Premises: water, gas, electricity,
sewer service and non-hazardous waste pick-up. The costs of such utilities shall be included in Operating Expenses. Tenant shall be responsible for arranging for telephone and other electronic communications services, at the Premises and shall pay
the costs of such utilities directly. Landlord will work in good faith with Tenant to provide access to a cable or satellite TV feed to the Premises, subject to agreement of the parties with respect to allocation of costs of installation and ongoing
monthly service costs. 
 7.7. Taxes on Tenant’s Property and Business. Tenant shall pay prior to delinquency all taxes levied
or assessed by any local, state or federal authority upon the conduct of Tenant’s business in the Premises or upon Tenant’s Property (as defined in Section 9.6) and shall deliver satisfactory evidence of such payment to Landlord upon
request. If the assessed value of the Property is increased by the inclusion of a value placed upon Tenant’s Property, Tenant shall pay to Landlord, within thirty (30) days after written demand, the taxes so levied against Landlord, or the
portion of Landlord’s taxes resulting from said increase in assessment, as determined from time to time by Landlord. 
 7.8.
Electricity Reimbursement for Tenant’s Special Systems. Landlord shall have the right to require that Tenant reimburse Landlord for the electricity use of Tenant’s Special Systems which utilize a large amount of electricity, which may
include but are not limited to Tenant’s Server Room Computers, Server Room Cooling Systems, or other systems not typical for general office use (“Tenant’s Special Systems”). Landlord may require Tenant
to measure such electricity use using E-Mon D-Mon kWh Meters, and the electricity reimbursement shall be calculated by Landlord based on the actual electric rates paid by the Property. 

7.9. Energy and Resource Consumption. Landlord may voluntarily cooperate in a reasonable manner with the efforts of governmental
agencies and/or utility suppliers in reducing energy or other resource consumption within the Property. Tenant shall not be entitled to terminate this Lease or to any reduction in or abatement of rent by reason of such compliance or cooperation.
Tenant agrees at all times to cooperate fully with Landlord and to abide by all reasonable rules established by Landlord (i) in order to maximize the efficient  

  
 14 

 
operation of the electrical, heating, ventilating and air conditioning systems and all other energy or other resource consumption systems with the Property and/or (ii) in order to comply
with the requirements and recommendations of utility suppliers and governmental agencies regulating the consumption of energy and/or other resources. 

8. REPAIRS, MAINTENANCE AND SERVICES 

8.1. Landlord’s Obligations. Except as specifically provided in this Lease, Landlord shall not be required to furnish any

County, California. Tenant shall reimburse Landlord within fifteen (15) days after written demand as Additional Rent for any out-of-pocket expenses incurred by Landlord in connection with any repairs or replacements required to be made by
Tenant, including, without limitation, any reasonable fees charged by Landlord’s contractors to review plans and specifications prepared by Tenant (if applicable). 

  
 15 

 8.3. Security. Tenant shall be solely responsible for the security of the Premises and
Tenant’s Agents while in or about the Premises. Any security services provided to the Property by Landlord shall be at Landlord’s sole discretion and Landlord shall not be liable to Tenant or Tenant’s Agents for any failure to provide
security services or any loss, injury or damage suffered as a result of a failure to provide security services. 
 8.4. Landlord’s
Right To Cure Defaults. In an Event of Default occurs with respect to any of Tenant’s Obligations, Landlord, in its sole and absolute discretion, and upon fifteen (15) days written notice to Tenant, shall have the right to cure such
Event of Default by Tenant, and Tenant shall reimburse Landlord for all reasonable costs and expenses incurred by Landlord to effect such cure within thirty (30) days after Landlord’s demand for all out-of-pocket costs and expense incurred
by Landlord in connection with such cure (as shown by reasonable back-up documentation). 
 8.5. Special Services. If Tenant requests
any services from Landlord other than those for which Landlord is obligated under this Lease, Tenant shall make its request in writing and Landlord may elect in its sole discretion whether to provide the requested services. Landlord shall notify
Tenant of its decision in writing within ten (10) days after receipt of Tenant’s request and, if Landlord offers to provide such services, the proposed cost thereof (which shall be the prevailing rate being charged for such services by
other property owners and property managers of comparable buildings in the area of the Property). If Tenant elects to accept such offer, and Landlord provides any special services to Tenant, Tenant shall pay the cost of such services as Additional

9.2. Alterations by Tenant. Tenant shall not make or permit any alterations to the Building Systems, and shall not make or permit any
alterations, installations, additions or improvements, structural or otherwise (collectively, “Alterations”) in or to the Premises or the Building without Landlord’s prior written consent, which Landlord shall not
unreasonably withhold, condition or delay. Landlord shall respond to any request by Tenant to make any Alteration within fifteen (15) days after receipt of such request for consent from Tenant. Notwithstanding the foregoing, Landlord’s

 9.3. Project Requirements. The provisions of this Section 9.3 shall apply to all
Alterations, whether or not requiring Landlord’s approval (unless otherwise noted):

12.2. Environmental Release. Landlord hereby informs Tenant that detectable amounts of Hazardous Materials may have come to be located

rights conferred upon it by the provisions of Section 1542 of the California Civil Code, which reads as follows: 
 A general release

provide Landlord a complete list of all Hazardous Materials (including MSDS sheets for all such Hazardous Materials) used or stored by Tenant or any of Tenant’s Agents or subtenants at the Premises, excluding standard janitorial and office

management of such Hazardous Materials. 
 12.4. Remediation of Hazardous Materials. Tenant shall, upon demand of Landlord, and at
Tenant’s sole cost and expense, promptly take all actions to remediate the Property from the effects of any Tenant’s Hazardous Materials. Such actions shall include, but not be limited to, the investigation of the environmental condition
of the affected portion of the Property, the preparation of any feasibility studies, reports or remedial plans, and the performance of any cleanup, remediation, containment, operation, maintenance, monitoring or restoration work, whether on or off
of the Property. Tenant shall take all actions necessary to remediate the Property from the effects of such Tenant’s Hazardous Materials to the condition of the Property immediately preceding the release of Tenant’s Hazardous Materials.
All work shall be performed by one or more contractors selected by Tenant and reasonably approved in advance and in writing by Landlord. Tenant shall proceed continuously and diligently with such investigatory and remedial actions, provided that in
all cases such actions shall be in accordance with all Applicable Laws. Any such actions shall be performed in a good, safe and workmanlike manner. Tenant shall pay all costs in connection with such investigatory and remedial activities, including

activities and any that are submitted to any governmental entity. Promptly upon completion of such investigation and remediation, Tenant shall permanently seal or cap all monitoring wells and test holes in accordance with sound engineering practice
and in compliance with Applicable Laws, remove all associated equipment, and restore the Property to the condition of the Property immediately preceding the release of Tenant’s Hazardous Materials which shall include, without limitation, the

 12.5. Indemnity. Tenant shall
indemnify, defend (by counsel reasonably acceptable to Landlord), protect and hold Landlord and Landlord’s trustees, directors, officers, agents and employees and their respective successors and assigns (collectively,
“Landlord’s Agents”), free and harmless from and against any and all claims, liabilities, penalties, forfeitures, losses or expenses (including reasonable attorneys’ and consultants’ fees and oversight and
response costs) to the extent arising from (a) Environmental Activity by Tenant or Tenant’s Agents; or (b) failure of Tenant or Tenant’s Agents to comply with any Environmental Law with respect to Tenant’s Environmental
Activity; or (c) Tenant’s failure to remove Tenant’s Hazardous Materials as required in Section 12.4. Tenant’s obligations hereunder shall include, but not be limited to, the burden and expense of defending all claims, suits
and administrative proceedings (with counsel reasonably approved by Landlord), even if such claims, suits or proceedings are groundless, false or fraudulent; conducting all negotiations of any description; and promptly paying and discharging when
due any and all judgments, penalties, fines or other sums due against or from Landlord or the Premises. Prior to retaining counsel to defend such claims, suits or proceedings, Tenant shall obtain Landlord’s written approval of the identity of
such counsel, which approval shall not be unreasonably withheld, conditioned or delayed. In the event Tenant’s failure to surrender the Premises at the expiration or earlier termination of this Lease free of Tenant’s Hazardous Materials
prevents Landlord from reletting the Premises, or reduces the fair market and/or rental value of the Premises or any portion thereof, Tenant’s indemnity obligations shall include all actual losses to Landlord arising therefrom. Tenant shall
have no liability for Hazardous Materials on, beneath and/or in the vicinity of the Property on the Effective Date or not caused or permitted by Tenant or Tenant’s Agents during the Term. 

  
 22 

 
Landlord shall indemnify, defend and hold Tenant and Tenant’s Agents harmless from and against any and all claims, liabilities, penalties, forfeitures, losses or expenses (including

Effective Date or (b) failure of Landlord or Landlord’s Agents to comply with any Environmental Law. 
 12.6. No Lien.
Tenant shall not suffer any lien to be recorded against the Property as a consequence of any Tenant’s Hazardous Materials, including any so-called state, federal or local “super fund” lien related to the remediation of any
Tenant’s Hazardous Materials in or about the Property. 
 12.7. Investigation. If Landlord has a reasonable basis to believe
that a release of any Harzardous Materials has occurred in the Premises, Landlord shall have the right to enter and conduct an inspection of the Premises or the Property, including invasive tests, at any reasonable time and upon reasonable advance
notice, to determine whether Tenant is complying with the terms of this Lease, including but not limited to the compliance of the Property and the Premises and the activities thereon with Environmental Laws (the “Environmental
Investigation”). Landlord shall have the right, but not the obligation, to retain at its expense an independent professional consultant to enter the Property and/or the Premises to conduct such an inspection, and to review any report
prepared by or for Tenant concerning such compliance. In the event the Environmental Investigation identifies any deficiencies in the compliance of the Property and/or the Premises with Environmental Laws due to any Environmental Activity by Tenant
or Tenant’s Agents, Tenant shall promptly correct any such deficiencies identified in the Environmental Investigation, and document to Landlord that corrective action has been taken. If a material deficiency is found, Tenant shall also
reimburse Landlord for the reasonable cost of the Environmental Investigation. If the Environmental Investigation identifies any such deficiency in compliance of the Property and/or the Premises with Environmental Laws due to any Environmental
Activity by Tenant or Tenant’s Agents, then, within nine (9) months of the date of the Environmental Investigation, Landlord may request a detailed review of the status of such violation by a consultant selected by Landlord (the
“Supplemental Investigation”). Tenant shall pay for the reasonable cost of any Supplemental Investigation. A copy of the Supplemental Investigation shall be promptly supplied to Landlord and Tenant when it becomes available.

 12.8. Right to Remediate. If an Event of Default shall occur with respect to any of Tenant’s obligations or agreements
pertaining to Hazardous Materials or Environmental Laws, then Landlord shall have the right, but not the obligation, without limitation of any other rights of Landlord hereunder, upon twenty-four (24) hours notice to Tenant (except in the case
of an emergency, in which event no such notice shall be required), to enter the Premises personally or through Landlord’s agents, employees and contractors and perform the same, provided, that Landlord shall make reasonable commercial efforts
not to interfere with Tenant’s normal business operations. Tenant agrees to indemnify Landlord for the costs thereof and liabilities therefrom as set forth above in this Article 12. 

12.9. Notices. Tenant shall immediately notify Landlord of any inquiry, test, claim, investigation or enforcement proceeding by or
against Tenant or the Premises known to Tenant concerning any Hazardous Materials. Tenant shall immediately notify Landlord of any release or discharge of Hazardous Materials on, in under or about the Premises. Tenant acknowledges that Landlord, as
the owner of the Property, shall have the sole right at its election and at Tenant’s expense, to negotiate, defend, approve and appeal any action taken or order issued with regard to Tenant’s Hazardous Materials by any applicable
governmental authority. 

  
 23 

 12.10. Surrender. Tenant shall surrender the Property and the Premises to Landlord, upon
the expiration or earlier termination of the Lease, free of Tenant’s Hazardous Materials in accordance with the provisions of this Article 12. 

12.11. Survival; Insurance. The provisions of this Article 12 shall survive the expiration or earlier termination of this Lease. The
provisions of Article 13 (Insurance) shall not limit in any way Tenant’s obligations under this Article 12. 
 13. INDEMNITY;

matter covered by Tenant’s indemnification obligations under this Section or under Section 12.5, Tenant, upon notice from Landlord, shall at its sole cost and expense, resist or defend such claim, action or proceeding by counsel approved
by Landlord. Notwithstanding the foregoing, Landlord may retain its own counsel to defend or assist in defending any claim, action or proceeding involving potential liability of Five Million Dollars ($5,000,000) or more, and Tenant shall pay the
reasonable fees and disbursements of such counsel. Tenant’s obligations under this Section shall survive the expiration or earlier termination of this Lease. 

13.2. Insurance. Tenant shall procure at its sole cost and expense and keep in effect during the Term: 

(a) commercial general liability insurance covering Tenant’s operations in the Premises and the use and occupancy of the Premises
and the Property and any part thereof by Tenant. Such insurance shall include broad form contractual liability insurance coverage insuring Tenant’s obligations under this Lease. Such coverage shall be written on an “occurrence” form

 24 

 
hereunder by Tenant, shall provide that it is primary insurance, shall provide for severability of interests, shall further provide that an act or omission of one of the named insureds which
would void or otherwise reduce coverage as to that insured shall not reduce or void the coverage as to any other insured, shall afford coverage for claims based on acts, omissions, injury or damage which occurred or arose (or the onset of which
occurred or arose in whole or in part during the policy period), and Tenant shall endeavor to cause such insurance to provide that Landlord will receive thirty (30) days’ written notice from the insurer prior to any cancellation or
material change of coverage; 
 (b) commercial property insurance, including sprinkler leakages, vandalism and malicious mischief
and plate glass damage covering all the items specified as Tenant’s Property and all other property of every description including stock-in-trade, furniture, fittings, installations, alterations, additions, partitions and fixtures or anything
in the nature of a leasehold improvement made or installed by or on behalf of the Tenant in the Premises in an amount of not less than one hundred percent (100%) of the full replacement cost thereof as shall from time to time be determined by
Tenant, in the form specified in Section 13.3. below; 
 (c) Worker’s Compensation Insurance in the amounts and coverages
required under worker’s compensation, disability and similar employee benefit laws applicable to Tenant and/or the Premises from time to time, and Employer’s Liability Insurance, with limits of not less than one million dollars

 (d) business income insurance with extra expense insurance in an
amount sufficient to insure payment of Rent for a period of not less than twelve (12) months during any interruption of Tenant’s business by reason of the Premises or Tenant’s Property being damaged by casualty; and 

(e) any other form or forms of insurance (excluding flood, earthquake and terrorism insurance) Landlord may reasonably require from
time to time, but only in such amounts and for such insurable risks that landlords of comparable buildings in the vicinity of the Property then require tenants of comparable amounts of space to carry. 

13.3. Policies. All policies of insurance required of Tenant shall be issued by insurance companies with general policyholders’
rating of not less than A-1as rated in the most current available “Best’s Insurance Reports,” and not prohibited from doing business in the State of California, and shall, with respect to the commercial general liability policy,
include Landlord and the property manager of the Building as additional insureds. Such policies, with the exception of Worker’s Compensation Insurance, shall be for the mutual and joint benefit and protection of Landlord, Tenant and the
required additional insureds. Certificates of Tenant’s policies shall be delivered to Landlord within ten (10) days prior to the delivery of possession of the Premises to Tenant and thereafter on or before the renewal date for each such
policy. All commercial general liability and property damage policies shall contain a provision that Landlord and any other additional insured, although named as additional insureds, shall nevertheless be entitled to recover under said policies for
a covered loss occasioned by it, its servants, agents and employees, by reason of Tenant’s negligence. As often as any policy shall expire or terminate, renewal or additional policies shall be procured and maintained by Tenant in like manner
and to like extent. Tenant shall endeavor to cause such policies of insurance to provide that the company writing said policy will give to Landlord thirty (30) days’ notice in writing in advance of any cancellation or lapse or of the
effective date of any reduction in the amounts of insurance. All commercial general liability, property damage and other casualty policies shall be written on an occurrence basis. Landlord’s coverage shall not be contributory. No policy shall

 25 

 13.4. Landlord’s Rights. Should Tenant fail to take out and keep in force each
insurance policy required under this Article 13, or should such insurance not be approved by Landlord and should the Tenant not rectify the situation within five (5) business days after written notice from Landlord to Tenant, Landlord shall
have the right, without assuming any obligation in connection therewith, to purchase such insurance at the sole cost of Tenant, and all costs incurred by Landlord shall be payable to Landlord by Tenant within thirty (30) days after demand as
Additional Rent and without prejudice to any other rights and remedies of Landlord under this Lease. 
 13.5. Waiver of Subrogation.
Notwithstanding anything to the contrary contained herein, to the extent permitted by their respective policies of insurance and to the extent of insurance proceeds received (or which would have been received had the party carried the insurance
required by this Lease) with respect to the loss, Landlord and Tenant each hereby waive any right of recovery against the other party and against any other party maintaining a policy of insurance with respect to the Property or any portion thereof
or the contents of the Premises or the Building for any loss or damage sustained by such other party with respect to the Premises, the Building or the Property, or any portion thereof, or the contents of the same or any operation therein, whether or
not such loss is caused by the fault or negligence of such other party. Either party shall notify the other party if the policy of insurance carried by it does not permit the foregoing waiver. 

13.6. No Liability. No approval by Landlord of any insurer, or the terms or conditions of any policy, or any coverage or amount of
insurance, or any deductible amount shall be construed as a representation by Landlord of the solvency of the insurer or the sufficiency of any policy or any coverage or amount of insurance or deductible and Tenant assumes full risk and
responsibility for any inadequacy of insurance coverage or any failure of insurers. 
 13.7. Landlord’s Insurance. Landlord
shall maintain during the Term (a) all risk or similar property insurance covering the Building and Property in the amount of the full replacement cost thereof, with such deductibles and coverage as shall be required by Landlord’s Lender
or as shall be carried by landlords of comparable buildings in the vicinity of the Property, if there is no loan on the Building. 
 14.
ASSIGNMENT AND SUBLETTING 
 14.1. Consent Required. Tenant shall not directly or indirectly, voluntarily or by operation of law,
sell, assign, encumber, pledge or otherwise transfer or hypothecate all or any part of its interest in or rights with respect to the Premises or its leasehold estate (collectively, “Assignment”), or permit all or any portion
of the Premises to be occupied by anyone other than itself or sublet all or any portion of the Premises (collectively, “Sublease”) without Landlord’s prior written consent, such consent not to be unreasonably withheld
(subject to Landlord’s rights as described in Sections 14.5). Landlord and Tenant acknowledge that it shall be reasonable for Landlord to withhold its consent in the following instances: 

(a) the use of the Premises would not comply with the provisions of this Lease; 

  
 26 

 (b) An Event of Default exists under this Lease; 

(c) The assignment or sublease is for a portion of a floor and would result in the dividing or sub-demising of a floor, unless Tenant
agrees to pay the costs of any demising wall, fire-rated corridor, and related improvements, plus the costs of restoration; except in no event shall there be more than two tenants (including Tenant) on any floor; 

(d) the proposed assignee or sublessee is a governmental agency; 

(e) in Landlord’s reasonable judgment, the use of the Premises by the proposed assignee or sublessee would involve occupancy by

(f) in Landlord’s reasonable judgment, the financial worth of the proposed assignee or sublessee does not meet the credit
standards applied by Landlord; 
 (g) the proposed assignee or sublessee (or any of its affiliates) has been in material default
under a lease, has been in litigation with a previous landlord, or in the ten years prior to the assignment or sublease has filed for bankruptcy protection, has been the subject of an involuntary bankruptcy, or has been adjudged insolvent; 

(h) Landlord has experienced a previous default by or is in litigation with the proposed assignee or sublessee; 

(i) in Landlord’s reasonable judgment, the Premises or any part of the Building, will be used in a manner that will violate any
Applicable Law; 
 (j) the proposed assignee or sublessee is a tenant in the Building or 8000 Marina Boulevard, Brisbane, either as
of the date of this Lease or at the time of Notice, or has within the prior six months been offered to Lease other office space in the Building or 8000 Marina Boulevard, Brisbane, by Landlord; or 

(k) the proposed assignment or sublease fails to include all of the terms and provisions required to be included therein pursuant to
this Article 14. 
 14.2. Notice. If Tenant desires to enter into a Sublease of all or any portion of the Premises or Assignment of
this Lease (except as provided in Section 14.7), it shall give written notice (the “Transfer Notice”) to Landlord of its intention to do so, which notice shall contain (a) the name and address of the proposed
assignee, subtenant or occupant (the “Transferee”), (b) the nature of the proposed Transferee’s business to be carried on in the Premises, (c) the terms and provisions of the proposed Assignment or Sublease,
and (d) such financial information as Landlord may reasonably request concerning the proposed Transferee (hereafter the “Complete Transfer Notice”). 

14.3. Terms of Approval. Landlord shall respond to Tenant’s request for approval within fifteen (15) days after receipt of
the Complete Transfer Notice. If Landlord approves the proposed Assignment or Sublease, Tenant may, not later than thirty (30) days thereafter, enter into the Assignment or Sublease with the proposed Transferee upon the terms and conditions set
forth in the Transfer Notice. 

  
 27 

 14.4. Excess Rent. For any Assignment or Sublease (other than a Permitted Transfer under
Section 14.7), fifty percent (50%) of the Excess Rent received by Tenant shall be paid to Landlord as and when received by Tenant. “Excess Rent” means the gross revenue received from the Transferee during the
Sublease term or with respect to the Assignment, less (a) the gross revenue received by Landlord from Tenant during the period of the Sublease term or concurrently with or after the Assignment; (b) any reasonably documented tenant
improvement allowance or other economic concession (planning allowance, moving expenses, etc.), paid by Tenant to or on behalf of the Transferee; (d) customary and reasonable external brokers’ commissions to the extent paid and documented;
(e) reasonable attorneys’ fees; and (f) reasonable costs of advertising the space for Sublease or Assignment (collectively, “Transfer Costs”). Tenant shall not be required to pay to Landlord any Excess Rent
until Tenant has recovered its Transfer Costs.

Tenant’s Transfer Notice shall also include a written offer that includes all of the substantial business terms that Tenant has offered to a Transferee and shall offer to Transfer to Landlord, Tenant’s interest in the portion of the
Premises offered to the Transferee on such terms and conditions (the “Offer”). Landlord shall have fifteen (15) days from Landlord’s receipt of the Offer to accept the Offer by written notice to Tenant or to approve
or disapprove the Transfer as provided in Section 14.3. If Landlord accepts the Offer, Landlord and Tenant shall consummate the Transfer within fifteen (15) days after Landlord’s written notice of acceptance. The Transfer shall be
consummated by Tenant’s delivery to Landlord of a good and sufficient assignment of lease or sublease. If Landlord does not accept the Offer, but approves the Transfer, then in the event the terms of the Transfer are materially changed during
subsequent negotiations to be more favorable to the Transferee, Tenant shall again deliver to Landlord an Offer in accordance with this Section, offering the interest to Landlord on such more favorable terms. Landlord shall then have another period
of fifteen (15) days after receipt of such Offer to accept such Offer. 
 14.6. No Release. No Sublease or Assignment by Tenant
nor any consent by Landlord thereto shall relieve Tenant of any obligation to be performed by Tenant under this Lease. Any Sublease or Assignment that is not in compliance with this Article shall be null and void and, at the option of Landlord,
shall constitute an Event of Default by Tenant under this Lease, and Landlord shall be entitled to pursue any right or remedy available to Landlord under the terms of this Lease or under the laws of the State of California. The acceptance of any
Rent or other payments by Landlord from a proposed Transferee shall not constitute consent to such Sublease or Assignment by Landlord or a recognition of any Transferee, or a waiver by Landlord of any failure of Tenant or other Transferor to comply
with this Article. 
 14.7. Permitted Transfers. Notwithstanding anything in this Article 14 to the contrary, but subject to the
provisions of Section 14.8 below, Landlord’s prior written consent shall not be required for any assignment of this Lease or sublease to any of the following (each a “Permitted Transferee”): (a) a successor
entity related to Tenant by merger, consolidation, or non-bankruptcy reorganization, or (b) a transferee of substantially all of Tenant’s assets (collectively, “Permitted Transfers”); provided that after such
assignment or transfer the operation of the business conducted in the Premises shall be in the manner required by this Lease and the Transferee shall have a net worth and credit quality equal to the greater of the Tenant’s net worth and credit
quality at the Commencement Date or the net worth and credit quality of the Tenant immediately prior to the consummation of the Assignment or sublease. 

14.8. Assumption of Obligations. Any Transferee shall, from and after the effective date of the Assignment, assume all obligations of
Tenant under this Lease with respect 

  
 28 

 
to the Transferred Space and shall be and remain liable jointly and severally with Tenant for the payment of Base Rent and Additional Rent, and for the performance of all of the terms, covenants,
conditions and agreements herein contained on Tenant’s part to be performed for the Term. No Assignment shall be binding on Landlord unless Tenant delivers to Landlord a counterpart of the Assignment and an instrument that contains a covenant
of assumption reasonably satisfactory in substance and form to Landlord, and consistent with the requirements of this Section. 
 14.9.
Landlord’s Costs. Tenant shall reimburse Landlord for its reasonable third-party costs (including, without limitation, the fees of Landlord’s counsel), incurred in connection with Landlord’s review and processing of documents
regarding any proposed assignment or sublease. 
 15. DEFAULT 

15.1. Event of Default. The occurrence of any of the following shall be an “Event of Default” on the part of
Tenant: 
 (a) Failure to pay any part of the Base Rent or Additional Rent, or any other sums of money that Tenant is required to
pay under this Lease where such failure continues for a period of three (3) days after written notice of default from Landlord to Tenant. Landlord’s notice to Tenant pursuant to this subsection shall be deemed to be the notice required
under California Code of Civil Procedure Section 1161. 
 (b) Failure to perform any other covenant, condition or requirement
of this Lease when such failure shall continue for a period of thirty (30) days after written notice thereof from Landlord to Tenant; provided that if the nature of the default is such that more than thirty (30) days are reasonably
required for its cure, then an Event of Default shall not be deemed to have occurred if Tenant shall commence such cure within said thirty (30) day period and thereafter diligently and continuously prosecute such cure to completion.
Landlord’s notice to Tenant pursuant to this subsection shall be deemed to be the notice required under California Code of Civil Procedure Section 1161.

acquiesce in the appointment of a receiver of itself or of the whole or any substantial part of the Premises. 
 (e) A court of
competent jurisdiction shall enter an order, judgment or decree appointing a receiver of Tenant or of the whole or any substantial part of the Premises and such order, judgment or decree shall not be vacated, set aside or stayed within thirty

court of competent jurisdiction shall enter an order, judgment or decree approving a petition filed against Tenant under any bankruptcy, insolvency, 

  
 29 

 
reorganization, dissolution or liquidation law or statute of the federal or state government or any subdivision of either now or hereafter in effect, and such order, judgment or decree shall not
be vacated, set aside or stayed within thirty (30) days from the date of entry of such order, judgment or decree, or a stay thereof shall be thereafter set aside. 

15.2. Remedies. Upon the occurrence and during the continuance of an Event of Default, Landlord shall have the following rights and
remedies: 
 (a) The right to terminate this Lease upon written notice to Tenant, in which event Tenant shall immediately surrender
possession of the Premises in accordance with Article 20. 
 (b) The right to bring a summary action for possession of the
Premises. 
 (c) The rights and remedies described in California Civil Code Section 1951.2, pursuant to which Landlord may
recover from Tenant upon a termination of the Lease, (i) the worth at the time of award of the unpaid rent which has been earned at the time of termination; (ii) the worth at the time of award of the amount by which the unpaid rent which
would have been earned after termination until the time of award exceeds the amount of such rental loss that Tenant proves could have been reasonably avoided; (iii) the worth at the time of the award of the amount by which the unpaid rent for
the balance of the term after the time of award exceeds the amount of such rental loss that Tenant proves could be reasonably avoided; and (iv) any other amount necessary to compensate Landlord for all the detriment proximately caused by
Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of events would be likely to result therefrom. The “worth at the time of award” of the amounts referred to in (i) and (ii) above is
computed by allowing interest at the rate of ten percent (10%) per annum. The “worth at the time of award” of the amount referred to in (iii) above 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%). The detriment proximately caused by Tenant’s failure to perform its obligations under this Lease or which in the ordinary course of events would be likely to result
therefrom includes, without limitation, (1) the unamortized portion of any brokerage or real estate agent’s commissions paid in connection with the execution of this Lease, (2) any direct costs or expenses incurred by Landlord in
recovering possession of the Premises, or maintaining or preserving the Premises after such default, (3) any direct costs or expenses incurred by Landlord in preparing the Premises for reletting to a new tenant, (4) any direct costs or
expenses incurred by Landlord in making any repairs or alterations to the Premises for such reletting, (5) leasing commissions, architect’s fees and any other costs necessary or appropriate to relet the Premises and (6) such amounts
in addition to or in lieu of the foregoing as may be permitted from time to time by Applicable Law to the extent that such payment would not result in a duplicative recovery. 

(d) In the event that Tenant abandons the Premises, the rights and remedies described in California Civil Code Section 1951.4
which allow Landlord to continue this Lease in effect and to enforce all of Landlord’s rights and remedies under this Lease, including the right to recover Base Rent, Additional Rent and other charges payable hereunder as they become due. Acts
of maintenance or preservation, efforts to relet the Premises or the appointment of a receiver upon Landlord’s initiative to protect its interest under this Lease shall not constitute a termination of Tenant’s right to possession. 

  
 30 

 (e) The right to keep this Lease in effect and enforce, by an action at law or equity,
all of its rights and remedies under this Lease, including the right to recover Rent as it becomes due, the right to make payments required by Tenant or perform Tenant’s obligations and be reimbursed by Tenant for the cost thereof, all as set
forth herein. 
 (f) The right to enjoin, and any other remedy or right now or hereafter available to a Landlord against a
defaulting tenant under the laws of the State of California or the equitable powers of its courts, and not otherwise specifically reserved herein. 

(g) If this Lease provides for a postponement of deferral of any Rent, or for commencement of payment of Rent to a date later than the
Commencement Date, or for a period of “free” Rent or any other Rent concession (collectively, “Abated Rent”), the right to demand immediate payment of the value of the Abated Rent. 

15.3. Cumulative Remedies. The various rights and remedies reserved to Landlord, including those not specifically described herein,
shall, to the extent that the exercise of such right and/or remedy does not result in a duplicative recovery, be cumulative and shall be in addition to every other right or remedy provided for in this Lease or now or hereafter existing at law or in
equity and the exercise of the rights or remedies provided for in this Lease or now or hereafter existing at law or in equity shall not preclude the simultaneous or later exercise by Landlord of any or all other rights and remedies. 

15.4. Waiver of Redemption by Tenant. Tenant hereby waives any right to relief against forfeiture of this Lease pursuant to California
Code of Civil Procedure Section 1179. 
 15.5. Landlord’s Right to Cure. If Tenant shall fail or neglect to do or perform
any covenant or condition required under this Lease and such failure shall not be cured within any applicable grace period, Landlord may, on five (5) days notice to Tenant, but shall not be required to, make any payment payable by Tenant
hereunder, discharge any lien, take out, pay for and maintain any insurance required hereunder, or do or perform or cause to be done or performed any such other act or thing (entering upon the Premises for such purposes, if Landlord shall so elect),
and Landlord shall not be or be held liable or in any way responsible for any loss, disturbance, inconvenience, annoyance or damage resulting to Tenant on account thereof. Tenant shall repay to Landlord within fifteen (15) days after demand the
entire out-of-pocket cost and expense incurred by Landlord in connection with the cure, including, without limitation, compensation to the agents, consultants and contractors of Landlord and reasonable attorneys’ fees and expenses. Landlord may
act upon shorter notice or no notice at all if necessary in Landlord’s reasonable judgment to meet an emergency situation or governmental or municipal time limitation or to protect Landlord’s interest in the Premises. Landlord shall not be
required to inquire into the correctness of the amount of validity or any tax or lien that may be paid by Landlord and Landlord shall be duly protected in paying the amount of any such tax or lien claimed and in such event Landlord also shall have
the full authority, in Landlord’s sole judgment and discretion and without prior notice to or approval by Tenant, to settle or compromise any such lien or tax. Any act or thing done by Landlord pursuant to the provisions of this Section shall
not be or be construed as a waiver of any such failure by Tenant, or as a waiver of any term, covenant, agreement or condition herein contained or of the performance thereof. 

15.6. Landlord’s Default. Landlord shall be in default under this Lease if Landlord fails to perform obligations required of
Landlord within thirty (30) days after written 

  
 31 

 
notice by Tenant to Landlord and to the holder of any first mortgage or deed of trust covering the Premises whose name and address shall have heretofore been furnished to Tenant in writing,
specifying wherein Landlord has failed to perform such obligations; provided, however, that if the nature of Landlord’s obligations is such that more than thirty (30) days are required for performance, then Landlord shall not be in default
if Landlord commences performance within such thirty (30) day period and thereafter diligently prosecutes the same to completion. Tenant shall be entitled to actual (but not consequential) damages in the event of an uncured default by Landlord,
but the provisions of Article 17 shall apply to any Landlord default and Tenant shall not have the right to terminate this Lease as a result of a Landlord default. 

16. LANDLORD’S RESERVED RIGHTS 

16.1. Control of Common Area. Landlord reserves the right, at any time and from time to time, to make alterations, additions, repairs,
replacements or improvements to all or any part of the Building (including the Building Structure and Building Systems), the Common Area and the Property. Landlord may make changes at any time and from time to time in the size, shape, location, use
and extent of the Common Area, and no such change shall entitle Tenant to any abatement of rent or damages. Landlord shall at all times during the Term have the sole and exclusive control of the Building Structure and the Common Area, and may at any
time and from time to time during the Term restrain any use or occupancy of the Common Area except as authorized by this Lease. Landlord specifically reserves the right to alter, reconfigure, replace, diminish, expand, or remove all or any part of
the executive conference center that currently exists on the second floor of the Building. Landlord may temporarily or permanently close any portion of the Common Area for repairs, maintenance, replacements or alterations, to prevent a dedication or
the accrual of prescriptive rights, or for any other reasonable purpose; provided, however, that Landlord shall use reasonable efforts not to materially adversely affect Tenant’s use of the Premises. Tenant’s rights in and to the Common
Area shall at all times be subject to the rights of Landlord and Tenant shall keep the Common Area free and clear of any obstructions created or permitted by Tenant or resulting from Tenant’s operations. 

16.2. Access. Landlord reserves (for itself and its agents, consultants, contractors and employees) the right to enter the Premises at
all reasonable times and, except in cases of emergency, after giving Tenant reasonable notice, to inspect the Premises (including, without limitation, environmental testing); to supply any service to be provided by Landlord hereunder; to show the
Premises to prospective purchasers or mortgagees; to show the Premises to prospective tenants during the last year of the Term; to post notices of non-responsibility; and to repair or maintain the Premises and the Building as required or permitted
by the terms of this Lease, without abatement of Rent, and may for that purpose erect, use and maintain necessary structures in and through the Premises and the Building where reasonably required by the character of the work to be performed. Tenant
hereby waives any claim for damages for any injury or inconvenience to or interference with Tenant’s business, any loss of occupancy or quiet enjoyment of the Premises or any other loss occasioned thereby, except to the extent caused by the
gross negligence or willful misconduct of Landlord in the exercise of its rights and provided that Landlord shall use reasonable efforts not to materially adversely affect Tenant’s use of the Premises. All locks for all of the doors in, upon
and about the Premises, excluding Tenant’s vaults and safes or special security areas (designated in advance in writing by Tenant) shall at all times be keyed to a master system and Landlord shall at all times have and retain a key with which
to unlock all of said doors. Landlord shall have the right to use any and all means that Landlord may deem necessary or proper to open said doors in an emergency in order to obtain entry to any portion of the Premises, and any such entry to the
Premises or portions thereof obtained by Landlord by any of said means, or otherwise, shall not 

  
 32 

 
under any circumstances be construed or deemed to be a forcible or unlawful entry into, or a detainer of, the Premises, or an eviction, actual or constructive, of Tenant from the Premises or any
portion thereof. 
 16.3. Easements. Landlord reserves the right to grant or relocate all easements and rights of way which Landlord
in its sole discretion may deem necessary or appropriate; provided that Tenant’s rights to use the Property is not materially impeded. 

16.4. Use of Additional Areas. Landlord reserves the exclusive right to use any air space above the Property, and the land beneath the
Premises; provided that such use shall not materially impede Tenant’s use of and access to the Premises. 
 16.5. Subordination.
This Lease shall be subject and subordinate at all times to: (a) all reciprocal easement agreements, and any ground leases or underlying leases which may now exist or hereafter be executed affecting the Property, and (b) the lien of any
mortgage or deed of trust which may now exist or hereafter be executed in any amount for which the Property, or any ground leases or underlying leases, or Landlord’s interest or estate in any of said items, is specified as security.
Notwithstanding the foregoing, Landlord shall have the right to subordinate or cause to be subordinated to this Lease any of the items referred to in clause (a) or (b) above, subject to compliance with the condition precedent set forth
below. In the event that any ground lease or underlying lease terminates for any reason or any mortgage or deed of trust is foreclosed or a conveyance in lieu of foreclosure is made for any reason, (i) no person or entity which as a result of
the foregoing succeeds to the interest of Landlord under this Lease (a “Successor”) shall be liable for any default by Landlord or any other matter that occurred prior to the date the Successor succeeded to
Landlord’s interest in this Lease, and (ii) Tenant shall, notwithstanding any subordination, attorn to and become the tenant of the Successor, at the option of the Successor. Tenant covenants and agrees, however, to execute and deliver,
upon demand by Landlord and in the form reasonably requested by Landlord, any additional documents evidencing the priority or subordination of this Lease with respect to any such ground leases, underlying leases, reciprocal easement agreements or
similar documents or instruments, or with respect to the lien of any such mortgage or deed of trust and Tenant’s failure to execute and deliver any such document within fifteen (15) days after such demand by Landlord shall constitute an
Event of Default without further notice. Landlord shall use commercially reasonable efforts to obtain the written agreement of the mortgagee or trustee named in any mortgage, deed of trust or other encumbrance, and any landlord under any ground
lease or underlying lease, that so long as an Event of Default by Tenant is not in existence, neither this Lease nor any of Tenant’s rights hereunder shall be terminated or modified, nor shall Tenant’s possession of the Premises be
disturbed or interfered with, by any trustee’s sale or by an action or proceeding to foreclose said mortgage, deed of trust or other encumbrance. Landlord represents and warrants to Tenant that on the Effective Date there is no ground lease or
underlying lease on the Property, and that the only deed of trust encumbering the Property is the deed of trust initially recorded as Instrument No. 2006-096832 in the Official Records of San Mateo County, California, as thereafter assigned
from time to time. 
 16.6. Non-Disturbance Agreement. Landlord shall use its reasonable best efforts to obtain for Tenant a
Non-Disturbance Agreement from its Lender, utilizing its Lender’s typical form of such agreement. 

  
 33 

 17. LIMITATION OF LANDLORD’S LIABILITY 

17.1. Limitation. Landlord shall not be responsible for or liable to Tenant and Tenant hereby releases Landlord, waives all claims
against Landlord and assumes the risk for any injury, loss or damage to any person or property in or about the Property by or from any cause whatsoever (other than Landlord’s negligence or misconduct or an Event of Default under this Lease)
including, without limitation, (a) acts or omissions of persons occupying adjoining premises, (b) theft or vandalism, (c) burst, stopped or leaking water, gas, sewer or steam pipes, (d) loss of utility service, (e) accident,
fire or casualty, (f) nuisance, and (g) work done by Landlord in the Property. There shall be no abatement of Rent and no liability of Landlord by reason of any injury to or interference with Tenant’s business arising from the making
of any repairs, alterations or improvements to any portion of the Property or to fixtures, appurtenances and equipment in the Property; provided, however, that in the event Landlord fails to perform its obligations to make repairs, alterations or
improvements or performs such obligations in a negligent manner in each case which results in Tenant being unable to operate its business in whole or in part at the Premises for a period of more than five (5) consecutive business days, then
Tenant shall be entitled to an appropriate abatement of Rent commencing on the sixth business day Tenant is unable so to operate and continuing until the Premises are again available for the full operation of Tenant’s business. Such Rent
abatement shall be Tenant’s only remedy in the event of a negligent interference with Tenant’s business and Tenant shall not be entitled to damages or to termination of this Lease arising from Landlord’s repairs, alterations or
improvements. No interference with Tenant’s operations in the Premises shall constitute a constructive or other eviction of Tenant. Tenant hereby waives and releases any right it may have to make repairs at Landlord’s expense under
Sections 1941 and 1942 of the California Civil Code, or under any similar law, statute or ordinance now or hereafter in effect. 
 17.2.
Sale of Property. It is agreed that Landlord may at any time sell, assign or transfer its interest as landlord in and to this Lease, and may at any time sell, assign or transfer its interest in and to the Property. In the event of any transfer
of Landlord’s interest in this Lease or in the Property, the transferor shall be automatically relieved of any and all of Landlord’s obligations and liabilities accruing from and after the date of such transfer; provided that the
transferee assumes all of Landlord’s obligations under this Lease, and provided, further, that Landlord shall deliver Tenant’s security deposit to the transferee. Tenant hereby agrees to attorn to Landlord’s assignee, transferee, or
purchaser from and after the date of notice to Tenant of such assignment, transfer or sale, in the same manner and with the same force and effect as though this Lease were made in the first instance by and between Tenant and the assignee, transferee
or purchaser. 
 17.3. No Personal Liability. In the event of any default by Landlord hereunder, Tenant shall look only to
Landlord’s interest in the Property and rents therefrom and any available insurance proceeds for the satisfaction of Tenant’s remedies, and no other property or assets of Landlord or any trustee, partner, member, officer or director
thereof, disclosed or undisclosed, shall be subject to levy, execution or other enforcement procedure for the satisfaction of Tenant’s remedies under or with respect to this Lease. 

18. DESTRUCTION 

18.1. Landlord’s Repair Obligation. If the Property or any portion thereof is damaged by fire or other casualty, Landlord shall
repair the same (including the Tenant Improvement Work, but not any Tenant’s Alterations); provided that (a) such repairs can be made under the laws and regulations of the federal, state and local governmental authorities having
jurisdiction within nine (9) months after the date of such damage (or in the case of damage occurring during the last twelve (12) months of the Term, provided that such repairs 

  
 34 

 
can be made within ninety (90) days after the date of such damage), (b) such repairs are fully covered (except for any deductible) by the proceeds of insurance maintained by Landlord,
and (c) the damage does not affect more than fifty percent (50%) of the replacement cost of the Building. 
 18.2. Notice.
Landlord shall notify Tenant within sixty (60) days after the date of damage whether or not the requirements for reconstruction and repair described in Section 18.1 are met. If such requirements are not met, Landlord shall have the option,
exercisable within sixty (60) days after the date of such damage either to: (a) notify Tenant of Landlord’s intention to repair such damage and the date on which Landlord estimates the reconstruction and repair will be substantially
completed, in which event this Lease shall continue in full force and effect (unless terminated by Tenant pursuant to Section 18.3 below), or (b) notify Tenant of Landlord’s election to terminate this Lease as of the date of the
damage. If such notice to terminate is given by Landlord, this Lease shall terminate as of the date of such damage. If within ten (10) days after receipt of a notice from Landlord electing to terminate this Lease because of the unavailability
of insurance proceeds, Tenant sends Landlord a notice electing to reimburse Landlord for the cost of such repairs that are in excess of the insurance proceeds available to Landlord, this Lease shall not terminate, and Landlord shall complete such
repairs. 
 18.3. Termination by Tenant. If Landlord elects to repair or is required to repair the damage and any such repair
(a) is not commenced by Landlord within one hundred twenty (120) days after the occurrence of such damage or destruction, or (b) is not or cannot practicably be substantially completed by Landlord within nine (9) months after the
occurrence of such damage or destruction (or in the case of damage occurring in the last twelve (12) months of the Term, within ninety (90) days), then in either such event Tenant may, at its option, upon written notice to Landlord to be
delivered within fifteen (15) days after receipt of Landlord’s notice or the expiration of the 120-day commencement period, elect to terminate this Lease as of the date of the occurrence of such damage or destruction. 

18.4. Rent Adjustment. In case of termination pursuant to Sections 18.2 or 18.3 above, the Base Rent and Operating Expenses shall be
reduced by a proportionate amount based upon the extent to which such damage interfered with the business carried on by Tenant in the Premises, and Tenant shall pay such reduced Base Rent and Operating Expenses up to the date of vacation of the
Premises. If Landlord is required or elects to make repairs, and Tenant does not terminate this Lease pursuant to Section 18.3, this Lease shall remain in full force and effect except that Tenant shall be entitled to a proportionate reduction
of Base Rent and Operating Expenses from the date of such casualty and during the period such repairs are being made by a proportionate amount based upon the extent of interference with Tenant’s operations in the Premises. The full amount of
Base Rent and Operating Expenses shall again become payable immediately upon the completion of such work of repair, reconstruction or restoration. The repairs to be made by Landlord under this Article shall not include, and Landlord shall not be
required to repair, any casualty damage to Tenant’s Property or any Alterations. 
 18.5. Tenant Obligations. If Landlord elects
or is required to repair, reconstruct or restore the Premises after any damage or destruction, Tenant shall be responsible at its own expense for the repair and replacement of any of Tenant’s Property and any Alterations that Tenant elects to
replace. 
 18.6. No Claim. Tenant shall have no interest in or claim to any portion of the proceeds of any property insurance or
self-insurance maintained by Landlord in connection with 

  
 35 

 
the damage. If Landlord is entitled and elects not to rebuild the Premises, Landlord shall relinquish to Tenant such claim as Landlord may have for any part of the proceeds of any insurance
maintained by Tenant under Section 13.2 of this Lease. 
 18.7. No Damages. If Landlord is required or elects to make any
repairs, reconstruction or restoration of any damage or destruction to the Premises under any of the provisions of this Article 18, Tenant shall not be entitled to any damages by reason of any inconvenience or loss sustained by Tenant as a result
thereof. Except as expressly provided in Section 18.4, there shall be no reduction, change or abatement of any rental or other charge payable by Tenant to Landlord hereunder, or in the method of computing, accounting for or paying the same.
Tenant hereby waives the provisions of Section 1932(2) and Section 1933(4) of the California Civil Code, or any other statute or law that may be in effect at the time of a casualty under which a lease is automatically terminated or a
tenant is given the right to terminate a lease due to a casualty. 
 19. EMINENT DOMAIN 

19.1. Taking. If all or any part of the Premises shall be taken as a result of the exercise of the power of eminent domain or any
transfer in lieu thereof, this Lease shall terminate as to the part so taken as of the date of taking or as of the date of final judgment, whichever is earlier, and, in the case of a partial taking of at least
twenty-five percent (25%) of the Rentable Area of the Premises, either Landlord or Tenant shall have the right to terminate this Lease as to the balance of the Premises by written notice to the other
within thirty (30) days after such date, provided, however, that a condition to the exercise by Tenant of such right to terminate shall be that the portion of the Premises taken shall be of such extent and nature as substantially to handicap,
impede or impair Tenant’s use of the balance of the Premises. If any material part of the Common Area shall be taken as a result of the exercise of the power of eminent domain or any transfer in lieu thereof, whether or not the Premises are
affected, Landlord shall have the right to terminate this Lease by written notice to Tenant within thirty (30) days of the date of taking. If any material part of the Common Area shall be taken as a result of the exercise of the power of
eminent domain or any transfer in lieu thereof, such that Tenant’s access to or use of the Premises is materially adversely affected or the number of parking spaces available to Tenant is materially reduced, Tenant shall have the right to
terminate this Lease by written notice to Landlord within thirty (30) days of the date of taking. 
 19.2. Award. In the event
of any taking, Landlord shall be entitled to any and all compensation, damages, income, rent, awards, or any interest therein whatsoever which may be paid or made in connection therewith, and Tenant shall assign to Landlord any right to compensation
or damages for the condemnation of its leasehold interest; provided that Tenant may file a claim for (a) Tenant’s relocation expenses, and (b) the taking of Tenant’s Property. 

19.3. Partial Taking. In the event of a partial taking of the Premises which does not result in a termination of this Lease, the Base
Rent and Operating Expenses shall be adjusted as follows: 
 (a) In the event of a partial taking, if this Lease is not terminated
pursuant to this Article 19, Landlord shall repair, restore or reconstruct the Premises to a useable state; provided that Landlord shall not be required to expend any sums other than those received pursuant to Section 19.2. 

  
 36 

 (b) During the period between the date of the partial taking and the completion of any
necessary repairs, reconstruction or restoration, Tenant shall be entitled to a reduction of Base Rent and Operating Expenses by a proportionate amount based upon the extent of interference with Tenant’s operations in the Premises; and 

(c) Upon completion of said repairs, reconstruction or restoration, and thereafter throughout the remainder of the Term, the Base Rent
and Operating Expenses shall be recalculated based on the remaining total number of square feet of Rentable Area of the Premises and the number of parking spaces available to Tenant. 

19.4. Temporary Taking. Notwithstanding any other provision of this Article, if a taking occurs with respect to all or any portion of
the Premises for a period of twelve (12) months or less, this Lease shall remain unaffected thereby and Tenant shall continue to pay Base Rent and Additional Rent and to perform all of the terms, conditions and covenants of this Lease, provided
that Tenant shall have the right to terminate this Lease if the taking continues beyond twelve (12) months or if, during the final two (2) years of the Term, the taking continues beyond four (4) months. In the event of any such
temporary taking, and if this Lease is not terminated, Tenant shall be entitled to receive that portion of any award which represents compensation for the use or occupancy of the Premises during the Term up to the total Base Rent and Additional Rent
owing by Tenant for the period of the taking, and Landlord shall be entitled to receive the balance of any award. 
 19.5. Sale in Lieu
of Condemnation. A voluntary sale by Landlord of all or any part of the Property to any public or quasi-public body, agency or person, corporate or otherwise, having the power of eminent domain, either under threat of condemnation or while
condemnation proceedings are pending, shall be deemed to be a taking under the power of eminent domain for the purposes of this Article. 

19.6. Waiver. Except as provided in this Article, Tenant hereby waives and releases any right it may have under any Applicable Law to
terminate this Lease as a result of a taking, including without limitation Sections 1265.120 and 1265.130 of the California Code of Civil Procedure, or any similar law, statute or ordinance now or hereafter in effect. 

20. SURRENDER 
 20.1.
Surrender. Upon the Termination Date, Tenant shall surrender the Premises to Landlord in as good order and repair as on the Commencement Date, reasonable wear and tear and damage by casualty excepted, free and clear of all letting and
occupancies and free of Hazardous Materials as required pursuant to Article 12. Subject to Article 9, upon any termination of this Lease all improvements, except for Tenant’s Property, shall automatically and without further act by Landlord or
Tenant, become the property of Landlord, free and clear of any claim or interest therein by Tenant, and without payment therefore by Landlord. 

20.2. Holding Over. Any holding over after the expiration of the Term with the consent of Landlord shall be construed to automatically
extend the Term on a month-to-month basis at a Base Rent equal to the greater of (a) one and one-half (1.5) times the then-current Base Rent , and (b) the Rent rate at which Landlord is then offering space in Building, and shall
otherwise be on the terms and conditions of this Lease to the extent applicable. Any holding over without Landlord’s consent shall entitle Landlord to exercise any or all of its remedies provided in Article 15, notwithstanding that
Landlord may elect to accept one or more payments of Base Rent and Operating Expenses from Tenant. 

  
 37 

 20.3. Quitclaim. At the expiration or earlier termination of this Lease, Tenant shall
execute, acknowledge and deliver to Landlord, within ten (10) days after written demand from Landlord to Tenant, any quitclaim deed or other document required by any reputable title company, licensed to operate in the State of California, to
remove the cloud or encumbrance created by this Lease from the Property. 
 21. FINANCIAL STATEMENTS 

So long as the Tenant hereunder is Hyperion Therapeutics, Inc. or another public company, Tenant shall have no obligation to provide any
financial statements to Landlord, since those financial statements are available to the public. If Tenant shall assign its rights and obligations under this Lease to a non-public company (the “Successor Tenant”), such
Successor Tenant shall tender to Landlord within fifteen (15) days after receipt of a written request any information reasonably requested by Landlord regarding the financial stability, credit worthiness or ability of such Successor Tenant to
pay the Rent due under this Lease. Landlord shall hold all such information confidential and shall not to disclose it to any third party, except as permitted by this Section 21. Tenant hereby represents and warrants to Landlord the following:
(a) that all documents provided by Tenant to Landlord in connection with the negotiation of this Lease are true and correct copies of the originals, (b) Tenant has not withheld any information from Landlord that is material to
Tenant’s credit worthiness, financial condition or ability to perform its obligations hereunder, (c) all information supplied by Tenant to Landlord is true, correct and accurate in all material respects, and (d) no part of the
information supplied by Tenant to Landlord contains any misleading or fraudulent statements. A default under this Article shall be a non-curable default by Tenant and Landlord shall be entitled to pursue any right or remedy available to Landlord
under the terms of this Lease or available to Landlord under the laws of the State of California. Landlord shall a be entitled to disclose any Successor Tenant’s financial information to (1) its attorneys, employees and financial advisors,
(2) potential purchasers of an interest in the Property, and (3) lenders contemplating making a loan to the Landlord to be secured by the Property, provided that such recipients are advised of the confidential nature of such information
and agree to maintain such confidentiality in writing. 
 22. TENANT CERTIFICATES 

Tenant, at any time and from time to time within fifteen (15) days after receipt of written notice from Landlord, shall execute,
acknowledge and deliver to Landlord or to any prospective lenders, purchasers, or ground lessees, a certificate of Tenant stating, to Tenant’s knowledge: (a) that Tenant has accepted the Premises, (b) the Commencement Date, the Rent
Commencement Date and Expiration Date of this Lease, (c) that this Lease is unmodified and in full force and effect (or, if there have been modifications, that same is in full force and effect as modified and stating the modifications),
(d) whether or not there are then existing any defenses against the enforcement of any of the obligations of Tenant under this Lease (and, if so, specifying same), (e) whether or not there are then existing any defaults by Landlord in the
performance of its obligations under this Lease (and, if so, specifying same), (f) the dates, if any, to which the Base Rent and Operating Expenses have been paid, and (g) any other factual information relating to the rights and
obligations under this Lease that may reasonably be required by any of such persons. Failure to deliver such certificate when due shall constitute an Event of Default. At the request of Tenant, Landlord shall execute, acknowledge and deliver to
Tenant a certificate with similar types of information and in the time period set forth above. Failure by either Landlord or Tenant to execute, acknowledge and deliver such certificate shall be conclusive evidence that this Lease is in full force
and effect and has not been modified except as may be represented by the requesting party. 

  
 38 

 23. RULES AND REGULATIONS; SIGNS 

23.1. Rules and Regulations. Tenant shall faithfully observe and comply with all rules and regulations and all reasonable modifications
thereof and additions thereto from time to time put into effect by Landlord (the “Rules and Regulations”). Landlord shall not enforce such Rules and Regulations in an unreasonable or discriminatory manner. In the event of any
conflict between the terms of this Lease and the terms, covenants, agreements and conditions of the Rules and Regulations, this Lease shall control. 

23.2. Signs. Landlord, at its expense, shall enter Tenant’s name in the Building directory located in the main lobby of the
Building and on the monument signs at the entry to the Property. Tenant, at its expense, shall have the right to install signage adjacent to the entrance doors to Tenant’s Premises identifying Tenant, subject to Landlord’s reasonable
consent. 
 24. INABILITY TO PERFORM 

If Landlord is unable to fulfill or is delayed in fulfilling any of Landlord’s obligations under this Lease, by reason of acts of God,
accidents, breakage, repairs, strikes, lockouts, other labor disputes, inability to obtain utilities or materials or by any other reason beyond Landlord’s reasonable control, then no such inability or delay by Landlord shall constitute an

any obligation of Tenant or Landlord under this Lease or to exercise any right, power or remedy consequent upon a breach thereof, no acceptance of full or partial Base Rent or Additional Rent during the continuance of any such breach by Landlord, or
payment of Base Rent or Additional Rent by Tenant to Landlord, and no acceptance of the keys to or possession of the Premises prior to the expiration of the Term by any employee or agent of Landlord shall constitute a waiver of any such breach or of
such term, covenant or condition or operate as a surrender of this Lease. No waiver of any breach shall affect or alter this Lease, but each and every term, covenant and condition of this Lease shall continue in full force and effect with respect to
any other then-existing or subsequent breach thereof. The consent of Landlord or Tenant given in any instance under the terms of this Lease shall not relieve Tenant or Landlord, as applicable, of any obligation to secure the consent of the other in
any other or future instance under the terms of this Lease. 
 29.3. Modification. Neither this Lease nor any term or provisions
hereof may be changed, waived, discharged or terminated orally, and no breach thereof shall be waived, altered or modified, except by a written instrument signed by the party against which the enforcement of the change, waiver, discharge or
termination is sought.

inure to the benefit of Landlord and Tenant and, except as otherwise provided or limited herein, their respective personal representatives and successors and assigns.

 41 

 29.9. No Counterclaim by Tenant. In the event Landlord commence any proceedings for
nonpayment of rent or other charges payable by Tenant under this Lease, Tenant will not interpose any counterclaim of whatever nature or description in any such proceedings. This shall not, however, be construed as a waiver of the Tenant’s
right to assert such claims in any separate action or actions brought by the Tenant. 
 29.10. Light and Air. Tenant covenants and
agrees that no diminution of light, air or view by any structure that may hereafter be erected (whether or not by Landlord) shall entitle Tenant to any reduction of the Base Rent or Additional Rent under this Lease, result in any liability of

Landlord nor Tenant shall record this Lease or a short form memorandum hereof without the consent of the other.

and such captions in no way define or limit the scope or intent of any provision of this Lease. 
 29.14. Review and Approval. The
review, approval, inspection or examination by Landlord of any item to be reviewed, approved, inspected or examined by Landlord under the terms of this Lease or the exhibits attached hereto shall not constitute the assumption of any responsibility
by Landlord for either the accuracy or sufficiency of any such item or the quality of suitability of such item for its intended use. Any such review, approval, inspection or examination by Landlord is for the sole purpose of protecting
Landlord’s interests in the Property and under this Lease, and no third parties, including, without limitation, Tenant or any person or entity claiming through or under Tenant, or the contractors, agents, servants, employees, visitors or
licensees of Tenant or any such person or entity, shall have any rights hereunder with respect to such review, approval, inspection or examination by Landlord.

any right or interest, including without limitation, any third party status or any right to enforce any provision of this Lease. 

29.16. Time of the Essence. Time is of the essence in respect of all provisions of this Lease in which a definite time for performance
is specified. 
 29.17. Modification of Lease. In the event of any ruling or threat by the Internal Revenue Service, or opinion of
counsel, that all or part of the Rent paid or to be paid to Landlord under this Lease will be subject to the income tax or unrelated business taxable income, Tenant agrees to modify this Lease to avoid such tax; provided that such modifications will
not result in any increase in Rent, or any increased obligations of Tenant under this Lease. Landlord will pay all Tenants’ reasonable costs incurred in reviewing and negotiating any such lease modification, including reasonable attorneys’
and accountants’ fees. 

  
 42

with and upon the advice of their respective legal counsel, all of whom have participated in the drafting hereof. Consequently, Landlord and Tenant agree that no party shall be deemed to be the drafter of this Lease and in the event this Lease is
ever construed by a court of law, such court shall not construe this Lease or any provision of this Lease against any party as the drafter of the Lease.

requirement for the performance of obligations or forbearance of an act by either party hereto which has not been completed prior to the termination of this Lease. Such survival shall be to the extent reasonably necessary to fulfill the intent
thereof, or if specified, to the extent of such specification, as same is reasonably necessary to perform the obligations and/or forbearance of an act set forth in such term, covenant or condition. Notwithstanding the foregoing, in the event a
specific term, covenant or condition is expressly provided for in such a clear fashion as to indicate that such performance of an obligation or forbearance of an act is no longer required, then the specific shall govern over this general provisions
of this Lease.

DETERMINATION OF PREVAILING MARKET RENT 

The term “Prevailing Market Rent” means the base monthly rent per rentable square foot, full service, for direct
leases from the landlord (as opposed to subleases) of space of comparable size to the Premises and in Class A office buildings located in the Brisbane & South San Francisco submarket in San Mateo County similar in quality to the
Premises for a comparable term, assuming that the first year of the term of the lease will be a new base year, and taking into account any additional rent and all other payments or escalations then being charged and allowances and economic
concessions being given for such comparable space over a comparable term. The Prevailing Market Rent shall be determined by Landlord and Landlord shall give Tenant written notice of such determination not later than thirty (30) days after
delivery by Tenant of Tenant’s notice of exercise of the Renewal Option. If Tenant disputes Landlord’s determination of the Prevailing Market Rent, Tenant shall so notify Landlord within fifteen (15) days following Landlord’s
notice to Tenant of Landlord’s determination and, in such case, the Prevailing Market Rent shall be determined as follows: 
 (a)
Within thirty (30) days following Tenant’s notice to Landlord that it disputes Landlord’s determination of the Prevailing Market Rent, Landlord and Tenant shall meet no less than two (2) times, at a mutually agreeable time and
place, to attempt to agree upon the Prevailing Market Rent. 
 (b) If within this 30-day period Landlord and Tenant cannot reach agreement
as to the Prevailing Market Rent, they shall each select one appraiser to determine the Prevailing Market Rent. Each such appraiser shall arrive at a determination of the Prevailing Market Rent and submit his or her conclusions to Landlord and
Tenant within thirty (30) days after the expiration of the 30-day consultation period described in (a) above. 
 (c) If only one
appraisal is submitted within the requisite time period, it shall be deemed to be the Prevailing Market Rent. If both appraisals are submitted within such time period, and if the two appraisals so submitted differ by less than ten (10) percent
of the higher of the two, the average of the two shall be the Prevailing Market Rent. If the two appraisals differ by more than ten (10) percent of the higher of the two, then the two appraisers shall immediately select a third appraiser who
will within thirty (30) days of his or her selection make a determination of the Prevailing Market Rent and submit such determination to Landlord and Tenant. This third appraisal will then be averaged with the closer of the previous two
appraisals and the result shall be the Prevailing Market Rent. 
 (d) All appraisers specified pursuant hereto shall be members of the
American Institute of Real Estate Appraisers with not less than five (5) years experience appraising office, research and development and industrial properties in the San Francisco/Peninsula/South Bay area. Each party shall pay the cost of the
appraiser selected by such party and one-half of the cost of the third appraiser plus one-half of any other costs incurred in the determination.
