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

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

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.

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

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.

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
