Utility

Services shall be billed and provided in the Building and the Project, the allocation of the costs of Utility Services between Building Utility Costs
(defined below), Project Utility Costs (defined below) and other buildings of the Project and the allocation of the cost of Utility Services (defined below) between tenants or occupants of the Project (including, without limitation, based upon
studies which allocate utility usages among the tenants or occupants of the Building or the Project based upon the estimated use by the respective tenants or occupants), shall be made by Landlord in good faith, acting consistently with Institutional
Owner Practices (defined below); provided that, in no event shall Tenant be responsible for any Utility Costs that are attributable to any Utility Services provided to any other Tenant within the Building or Project (which is simultaneously not
being provided to Tenant). Notwithstanding anything to the contrary in this Section 1.5, Landlord shall have the right at any time, upon not less than thirty (30) days prior written notice to Tenant, to separately meter the Premises (or
any portion thereof) for any of Tenant’s utilities, and thereafter Tenant shall pay to Landlord as Additional Charges the cost of such Utility Services provided to the Premises (or the applicable portion thereof) as reflected by such meter, and

sum of Building Utility Costs and Project Utility Costs, (ii) “Building Utility Costs” means the cost of providing Utility Services to the Building; provided, however, that Building Utility Costs shall be adjusted by Landlord

(100%) occupancy of the existing rentable area of the Building during such period, (iii) “Project Utility Costs” means the cost of providing Utility Services to the Project (other than to any building included in the
Project); provided, however, that Project Utility Costs shall be adjusted by Landlord for each expense year during which actual occupancy of the Project is less than one hundred percent (100%) of the Rentable Area of the Project in accordance
with sound accounting principles, to reflect one hundred percent (100%) occupancy of the existing rentable area of the Project during such period, (iv) “Utility Services” means, all utilities provided to the Building or
Project, including, without limitation, electricity, fuel, gas, water and similar utility services, and (v) “Institutional Owner Practices” means practices which are consistent with the practices of the majority of the

 (f) The parties hereto acknowledge and agree that Tenant shall remain in occupancy of the Premises (or portions thereof) during the construction of the Fifth and Sixth Amendment Tenant Improvements, that
Landlord’s construction of the Fifth and Sixth Amendment Tenant Improvements within the Premises (or portions thereof) shall not be deemed a constructive eviction of Tenant and that, during the construction of the Fifth and Sixth Amendment
Tenant Improvements, there may be a loss of utility services to Premises (or portions thereof) and that from time to time during construction of the Fifth and Sixth Amendment Tenant Improvements, Landlord may turn off some or all of the utilities
services to the Premises (or portions thereof) at reasonable times, upon at least forty-eight (48) hours prior written notice (or at any time and with no prior notice with respect to any portion of the Premises which, at such time, is not
occupied by Tenant), and Tenant acknowledges and agrees that neither Landlord nor its contractor shall be liable for any damage to, loss of or interference with Tenant’s equipment or operations in the Premises on account of the construction of

continues through the earlier to occur of (i) 4:30 p.m. on December 29, 2006 or (ii) the end of the second business day following the date of such notice, then at the election of Tenant exercisable by delivery of notice to Landlord,
this Amendment (and the Fifth Amendment) shall be null and void. The Additional Allowance may be used by Tenant for improvement of the Premises or any other purpose desired by Tenant. 
 1.8 Intentionally Omitted 
 1.9 Option to Extend. As of the date hereof, each of Article 32 of the Original Lease and Section 2 of the Third Amendment are hereby deleted in their entirety from the Lease (and shall have no
further force of effect) and the one-time, five (5) year Extension Option provided in Exhibit “C” attached hereto is substituted therefor.

Landlord solely owns that certain undeveloped real property located at 9755 Scranton Road, San Diego, CA, and, Landlord elects to construct a commercial office building (the “New Building”) thereon, then provided that the initial

Premises from the Building to the New Building, upon such terms as Landlord shall, in good faith be willing to accept. If Tenant so elects to negotiate for a relocation of its premises to any such New Building, Landlord and Tenant shall negotiate in
good faith with respect to the terms and conditions thereof, which terms and conditions shall be those which Landlord is, in good faith, then willing to lease space in the New Building to Tenant. The rights contained in this Section 1.10 are
personal to Original Tenant, are not transferable and may only be exercised by Original Tenant (and not by other any assignee, sublessee or other transferee of Tenant’s interest in the Lease) and only if Original Tenant then actually occupies
all of the rentable area contained in the Premises. 
 1.11 Additional Amendments to Lease. 
 (a) Assignment; Sublease. Section 18.1(a) of the Original Lease is hereby amended by adding the following
immediately following the last sentence of such Section 18.1(a). 
 “For the avoidance of doubt, in addition to any other grounds
available hereunder or under applicable Law for properly withholding consent to any Assignment or Sublease, Landlord’s consent shall be deemed reasonably withheld if: (i) either the proposed Transferee, or any person that directly or
indirectly controls, is controlled by, or is under common control with the proposed transferee leases or occupies space in the Project or is negotiating with, or has negotiated with Landlord within the preceding ninety (90) days, to lease space
in the Project, and at such time, Landlord has space in the Project that is capable of accommodating such proposed transferee’s needs or (ii) in Landlord’s good faith judgment, the proposed transferee is of a character or reputation
or is engaged in a business that is not consistent with the quality of the Building.” 
 (b) Parking.
Effective as of the New Rent Commencement Date, (i) Section 1.9(f) of the Fifth Amendment is deemed null, void and of no force or effect and (ii) in connection with the increase in the rentable area of the Premises, Tenant shall have the
right to lease from Landlord one hundred sixty (160) unreserved parking privileges at no charge to Tenant during the Extended Term. Subject to availability, Tenant shall have the right to elect to use up to forty (40) of its above
described one hundred sixty (160) unreserved parking privileges for parking, on a first come first served basis, in the gated surface lot located north of the Building (at no charge to Tenant during the Extended Term). Subject to availability,
as determined by Landlord in its non-discriminatory, good faith discretion, Landlord will provide Tenant with additional unreserved parking privileges at the Project. 
 2. Confidentiality. Tenant agrees that (i) the terms and provisions of the Lease as amended by this Amendment (collectively, “Terms and Provisions”), are confidential and constitute
proprietary information of Landlord and (ii) it shall not disclose, and it shall cause its partners, officers, directors, shareholders, employees, brokers and attorneys to not disclose (unless required by law (including, without limitation,
under any SEC requirements) and/or a court of competent jurisdiction) any of the Terms and Provisions to any other person (except its attorneys) without first obtaining the prior written consent of Landlord, which may be withheld in Landlord’s
sole discretion; provided, however that Landlord shall not unreasonably withhold its consent with respect to a request by Tenant to disclose the Terms and Provisions to Tenant’s representatives, agents and lenders for any good faith business
purpose of Tenant (where such disclosure is reasonably limited to the extent of such good faith business purpose). Other than as consented to in writing by Landlord pursuant to this Section 2, the disclosure of the Terms and Provisions by
Tenant or any of Tenant’s employees or agents to any other person shall constitute a breach of the Lease. Landlord agrees that this Section 2 shall apply to the information provided by Tenant to Landlord under Section 1.2(b)(i), above
and for such purposes, all references in the foregoing provisions to Tenant shall be deemed to refer to Landlord. 
 3.
Brokers. Tenant warrants and represents to Landlord that Tenant has had no dealings with any brokers or agents in negotiating and consummating this Amendment, except for Maguire Properties, L.P., representing Landlord
(“Broker”). Except for Broker, Tenant and Landlord shall each 

  

 5 

 
indemnify, defend and hold the other party free and harmless against any claim, cost, obligation, damage, liability or expense (including attorney’s
fees) suffered or incurred by the other party by reason of any claim asserted by any other broker or party in connection with this Amendment. 
 4. Execution and Enforcement. 
 4.1 Limitation of Liability 
 (a) Landlord’s Lease Undertakings. Notwithstanding anything to the contrary contained in this Amendment, the Lease or
in any exhibits, riders or addenda hereto attached (collectively the “Lease Documents”), it is expressly understood and agreed by and between the parties hereto that: (i) the recourse of Tenant or its successors or assigns
against Landlord (and the liability of Landlord to Tenant, its successors and assigns) with respect to (A) any actual or alleged breach or breaches by or on the part of Landlord of any representation, warranty, covenant, undertaking or
agreement contained in any of the Lease Documents or (B) any matter relating to Tenant’s occupancy of the Premises (collectively, “Landlord’s Lease Undertakings”) shall be limited solely to an amount equal to the
lesser of (x) Landlord’s equity interest in Building 1 and (y) the equity interest Landlord would have in Building 1 if Building 1 were encumbered by independent secured financing equal to eighty percent (80%) of the value of
Building 1; (ii) Tenant shall have no recourse against any other assets of Landlord or its officers, directors or shareholders; and (iii) except to the extent of Landlord’s interest in Building 1, no personal liability or personal
responsibility of any sort with respect to any of Landlord’s Lease Undertakings or any alleged breach thereof is assumed by, or shall at any time be asserted or enforceable against, Landlord or Maguire Properties, L.P., or against any of their
respective directors, officers, shareholders, members, employees, agents, constituent partners, beneficiaries, trustees or representatives, and (iv) at no time shall Landlord be responsible or liable to Tenant for any lost profits, lost
economic opportunities or any form of consequential damage as the result of any actual or alleged breach by Landlord of Landlord’s Lease Undertakings. 
 (b) Notwithstanding anything to the contrary contained in the Lease Documents, it is expressly understood and agreed by and between the parties hereto that no personal liability or personal responsibility of
any sort with respect to any of Tenant’s obligations under the Lease or any alleged breach thereof is assumed by, or shall at any time be asserted or enforceable against, Tenant’s directors, officers, shareholders, members, employees,
agents, constituent partners, beneficiaries, trustees or representatives. 
 4.2 Authority. Each individual
executing this Amendment on behalf of Tenant and Landlord hereby covenants and warrants that the respective party has full right and authority to enter into this Amendment and that the person signing on behalf of such party is authorized to do so.

 4.3 Entire Agreement; Remainder of Lease to Continue in Effect. The Lease, as amended by this Amendment,
contains all of the agreements of the parties hereto with respect to any matter covered or mentioned in this Amendment. No prior agreement, understanding, or representation pertaining to any such matter shall be effective for any purpose. Except as
amended hereby, the Lease, as hereby amended, shall in all other particulars, terms and conditions remain in full force and effect and is hereby ratified and confirmed by the parties hereto; in the event of any inconsistency between said Lease, as
amended, and this Amendment, the provisions of this Amendment shall prevail. It is acknowledged that no changes other than those herein specifically set forth have been made. 
 4.4 Counterparts. This Amendment may be executed in counterparts each of which shall be deemed as an original, but all of
which taken together shall constitute one and the same document. 
 4.5 Governing Law; Attorneys Fees. The
parties hereby agree that (a) the Lease, as amended hereby, shall be governed by and construed in accordance with the laws of the State of California (without regard to its conflict of laws principles) and (b) that the terms and conditions
of Section 30.17 shall apply to this Amendment.

 EXHIBIT “B” 
 INTENTIONALLY OMITTED

 EXHIBIT “C” 
 EXTENSION OPTION 
 1. Option to Extend. 
 1.1 Grant of Option. Tenant shall have one (1) option (the “Extension Option”) to extend the term of
this Lease as to the entire Premises then subject to this Lease for an additional term of sixty (60) months (“Extension Term”), subject to and upon the terms and conditions contained in this Exhibit “C”. The
Extension Term shall commence upon the day immediately following the Extended Term Expiration Date and shall end at 5 p.m. Pacific Standard Time on the last day of the sixtieth (60th) month following the commencement of the Extension Term. The
Extension Term shall be upon the same terms and conditions as are provided for in this Lease, as then amended, except that (i) if Tenant fails to timely exercise the Extension Option, the Extension Option shall lapse and Tenant shall have no
further right to extend the Term of the Lease, (ii) there shall be no further options to extend the Term pursuant to this Exhibit “C” or otherwise following the Extension Term, (iii) Tenant shall not be entitled to any
credit against Rent or Additional Charges or any other rent concession or rent allowance or abatement of Rent or Additional Charges, except as specifically provided in Section 1.3 of this Exhibit “C”. (iv) the Rent for the
Extension Term shall be as provided in Section 1.2 of this Exhibit “C” (but in no event shall the Rent for the Extension Term be less than the Rent in effect with respect to the entire Premises immediately prior to the date of
commencement of the Extension Term), (v) the Base Year applicable to such Extension Term shall be the calendar year in which the Adjustment Date (defined in Section 1.2 of this Exhibit “C”) occurs, and (vi) Landlord
shall have the option to document the Extension Option on Landlord’s current lease form at the time of Tenant’s delivery of the Extension Notice (defined below), provided that such lease form does not contain terms or conditions that are
materially adverse to the terms of the Lease. The Extension Option may be exercised only by Tenant giving written notice of exercise (an “Extension Notice”) to Landlord on or before the date that is not less than twelve
(12) months but not more than fifteen (15) months prior to the Extended Term Expiration Date. The Extension Option and all of the rights contained in this Exhibit “C” shall be personal to Kintera, Inc. (the
“Original Tenant”) and may only be exercised by the Original Tenant (and not any assignee, sublessee or other transferee of all or any portion of Tenant’s interest in this Lease except for Permitted Transferees described under
Section 18.5 of the Lease to which all of Tenant’s interest in this Lease is assigned) and then only if Tenant then occupies the entire Premises; any attempted exercise of an Extension Option under any other circumstances shall, at the
election of Landlord, be null and void and of no force or effect. 
 1.2 Rent. The Rent per month payable for
the Premises during the Extension Term (the “Extension Term Rent”) shall be equal to (i) the Rentable Area of the Premises then subject to this Lease, multiplied by (ii) the monthly FMRR (defined in Section 1.3 of
this Exhibit “C”) for the Premises as of the first day (an “Adjustment Date”) of the Extension Term, as determined in accordance with this Exhibit “C”; provided, however, that in no event shall the
Rent during the Extension Term be less than the Rent for the period immediately prior to the Extension Term. 
 1.3
Definition of FMRR. The “FMRR” of the Premises for a particular Extension Term shall be equal to the monthly rent per square foot of Rentable Area that Landlord has agreed to accept, or if Landlord determines that there
has not been a reasonable number of then current comparable transactions in the Building, that landlords of the Comparable Buildings (as defined below) have agreed to accept, and sophisticated nonaffiliated tenants of the Building or Comparable
Buildings have agreed to pay, in then current arms-length, nonrenewal, nonequity (i.e., not being offered equity in the building), transactions for comparable space (in terms of condition, floor location, view and floor height) of a comparable size
(in terms of square feet of Rentable Area), for a nonrenewal term equal to the Extension Term and commencing as of the first day of the Extension Term, which annual rent per square foot shall take into account and make adjustment for the existence,
timing and amount of any increases in rent following term commencement in the comparison transactions, and shall at all times take into consideration and make adjustment for all other material differences in all terms, conditions or factors
applicable to the transaction in question hereunder or applicable to one or more of the comparison transactions used to determine the FMRR which a sophisticated tenant or sophisticated landlord would believe would have a material impact on a
“fair market rental” determination; provided, however, that (i) the rent for all comparison transactions shall be grossed up to reflect payment of operating expenses and taxes in excess of a base year as of the year of commencement of
the transaction, (ii) the presence, amount or absence of brokerage commissions in either the subject transaction or the comparison transactions shall be disregarded, (iii) any rent free period provided for construction of tenant
improvements (but not any other free rent period) shall be disregarded, and (iv) if any tenant improvements or allowance provided for in comparable transactions shall be taken into account, the value to Tenant of any existing improvements in
the Premises shall also be accounted for in the calculation of the FMRR. If in determining the FMRR for a subject transaction hereunder, if is determined that free rent or cash allowances (collectively, “Concessions”) should be
granted, Landlord may, at Landlord’s sole option, elect all or any portion of the following: (A) to grant some or all of the Concessions to Tenant as free rent or as an improvement allowance, or (B) to adjust the monthly installments
of the Extension Term Annual Base Rent to be an effective rental rate which takes into consideration and deducts from monthly rent the amortized amount of the total dollar value of such Concessions, amortized on a straight line basis over the
Extension Term (in which case the Concessions so amortized shall not be granted to Tenant). As used herein, “Comparable Buildings” shall mean comparable Class “A” office buildings in the Sorrento Mesa submarket of San
Diego, California at the time the Extension Term commences. 
  

 10 

 1.4 Procedure for Determining the FMRR. For purposes of determining the
FMRR, the following procedure shall apply: 
 (a) If Tenant has timely given the Extension Notice, Landlord shall
within thirty (30) days thereafter deliver to Tenant a written notice of Landlord’s determination of what the FMRR would be during the Extension Term (“Landlord’s Extension Rent Notice”). Within ten (10) business
days after Tenant’s receipt of Landlord’s Extension Rent Notice, Tenant may give Landlord a written notice (“Tenant’s Extension Response Notice”) electing either (i) to accept the FMRR set forth in
Landlord’s Extension Rent Notice, in which case the FMRR shall be the FMRR set forth in Landlord’s Extension Rent Notice, or (ii) to not accept Landlord’s determination of the FMRR, in which case Landlord and Tenant shall
endeavor to agree upon the FMRR on or before the date that is ten (10) days after Landlord’s receipt of Tenant’s Extension Response Notice (the “Outside Agreement Date”). If Landlord and Tenant are unable to agree
upon the FMRR by the Outside Agreement Date, then the FMRR shall be determined by arbitration pursuant to paragraph (ii) below. If Tenant fails to deliver Tenant’s Extension Response Notice within the ten (10) business day period
following its receipt of Landlord’s Extension Rent Notice, Tenant shall conclusively be deemed to have rejected Landlord’s determination of the FMRR as set forth in Landlord’s Extension Rent Notice. 
 (b) If Landlord and Tenant shall fail to agree upon the FMRR by the Outside Agreement Date, then, within ten (10) days
thereafter, Tenant shall submit to Landlord Tenant’s determination of the FMRR and such determination, along with Landlord’s last written offer with respect to FMRR shall be submitted to arbitration (as Tenant’s and Landlord’s
“submitted FMRR,” respectively) in accordance with the following: 
 (i) Landlord and Tenant shall
each appoint one arbitrator who shall by profession be a real estate broker who shall have been active over the five (5) year period ending on the date of such appointment in the leasing of commercial high-rise properties in the San Diego,
California area. The determination of the arbitrators shall be limited solely to the issue as to whether Landlord’s or Tenant’s submitted FMRR is the closest to the actual FMRR, as determined by the arbitrators, taking into account the
requirements of this Exhibit “C”. Each such arbitrator shall be appointed within fifteen (15) days after the Outside Agreement Date. 
 (ii) The two arbitrators so appointed shall within ten (10) days of the date of the appointment of the last appointed arbitrator agree upon and appoint a third arbitrator who shall be a real estate broker
who shall have been active over the five (5) year period ending on the date of such appointment in the leasing of commercial high-rise properties in the San Diego, California area. 
 (iii) The three arbitrators shall within thirty (30) days of the appointment of the third arbitrator reach a decision as to
whether the parties shall use Landlord’s or Tenant’s submitted FMRR and shall notify Landlord and Tenant thereof. 
 (iv) The decision of the majority of the three arbitrators shall be binding upon Landlord and Tenant, shall be in writing and shall be non-appealable, and counterpart copies thereof shall be delivered to Landlord and Tenant. A
judgment or order based upon such award may be entered in any court of competent jurisdiction. In rendering their decision and award, the arbitrators shall have no power to vary, modify or amend any provision of this Lease. 
 (v) If either Landlord or Tenant fails to appoint an arbitrator within fifteen (15) days after the applicable Outside
Agreement Date, the arbitrator appointed by the other shall solely render a decision as to the FMRR, notify Landlord and Tenant thereof, and such arbitrator’s decision shall be binding upon Landlord and Tenant. 
 (vi) If the two arbitrators fail to agree upon and appoint a third arbitrator, or both parties fail to appoint an arbitrator, then
the appointment of the third arbitrator or any arbitrator shall be dismissed and the matter to be decided shall be promptly submitted to arbitration under the provisions of the American Arbitration Association, but subject to the instructions set
forth in this Exhibit “C”, 
 (vii) The cost of arbitration shall be paid by Landlord and Tenant
equally. 
 1.5 Conditions to Exercise of Each Extension Option. Notwithstanding any provision of this
Exhibit “C” to the contrary, at the election of Landlord, any attempted exercise by Tenant of an Extension Option shall be invalid and ineffective if, on the date of such attempted exercise or on the commencement of the Extension
Term, Tenant is in default under this Lease (beyond any applicable notice and grace periods) or Tenant occupies less than 90% of the Premises. If Tenant does not timely send the Extension Notice for the Extension Option pursuant to the provisions of
this Exhibit “C” within the applicable time period, time being of the essence, then Tenant shall be deemed to have forever waived and relinquished such Extension Option, and any other options or rights to renew or extend the term
effective after the then applicable Expiration Date shall terminate.
