          (iii) Preparation, Review and Approval of Tenant’s Construction Documents. Tenant shall, at its expense, consult with its architect, engineer, designer and such other consultants as it shall deem necessary for development and timely completion of certain documents as described in this Subsection (iii).

                         (III) To the extent the Tenant’s Construction Documents, as the case may be, in Landlord’s sole judgment, involve any modification of, or impact upon, the Property’s structural, mechanical, electrical or plumbing systems or components, then such approval may be withheld by Landlord in its absolute and sole discretion.

                         (IV) Tenant’s Construction Documents, as approved by Landlord and as modified by Tenant to take account of any changes reasonably requested by Landlord, are hereinafter considered to be “Issued for Construction.”

                         (V) Without limiting the generality of the foregoing, Tenant acknowledges that Landlord may disapprove documents submitted by Tenant under this Section 3(c)(iii) because the work detailed therein: (a) is likely to adversely affect Building systems, the structure of the Building or the safety of the Building and/or its occupants; (b) might impair Landlord’s ability to furnish services to Tenant or other tenants in the Building; (c) would increase the cost of operating the Building; (d) would violate any governmental laws, rules or ordinances (or interpretations thereof); (e) contains or uses hazardous or toxic materials or substances; (f) would adversely affect the appearance of the Building; (g) might adversely affect another tenant’s premises; (h) is prohibited by

any ground lease affecting the Building or any mortgage, trust deed or other instrument encumbering the Building; or (i) is likely to be substantially delayed because of unavailability or shortage of labor or materials necessary to perform such work or the difficulties or unusual nature of such work. The foregoing reasons, however, shall not be the only reasons for which Landlord may withhold its approval, whether or not such other reasons are similar or dissimilar to the foregoing. Neither the approval by Landlord of the Tenant Work or any plans, drawings, specifications or other items associated with the Tenant Work, nor Landlord’s performance, supervision or monitoring of the Tenant Work, shall constitute any warranty by Landlord to Tenant of the adequacy of the design for Tenant’s intended use of the Premises.

                    (C) Costs of Tenant’s Documents.

               (v) Tenant’s Contractor.

                    (A) The work shall be performed at Tenant’s expense by responsible contractors and subcontractors approved in advance by Landlord, who shall not in Landlord’s sole opinion, and who in fact do not, prejudice Landlord’s relationship with Landlord’s contractors or subcontractors or the relationship between such contractors and their subcontractors or employees, or disturb harmonious labor relations. Landlord hereby approves the following contractors: Tamora Construction, Patriot Construction and Commercial Construction. Tenant’s contractors and subcontractors shall comply with all insurance requirements and undertakings set forth in Exhibit D attached to the Lease, as the same may be changed by written notice from Landlord to Tenant from time to time during the Term.

Tenant shall submit to Landlord on or before the twentieth (20th) day of each month, a voucher for Tenant’s Costs (in the standard American Institute of Architects form) executed by Tenant’s Construction Representative and by a partner or officer of Tenant, setting forth in reasonable detail the amount of such Tenant’s Costs and identifying the material, labor, fees, and costs to which they relate, accompanied by (A) in the case of a request for reimbursement of costs paid by Tenant, (I) canceled checks, paid invoices or other evidence reasonably satisfactory to Landlord that Tenant has paid the sums sought to be reimbursed, and (II) a lien release executed by each of Tenant’s contractors which received payments for which Tenant is seeking reimbursement, and (B) in the case of a request for payment directly to a contractor or contractors, design professional or furniture vendor, copies of invoices for the work or items sought to be paid and a certification from Tenant’s Construction Representative that the work and items represented by such invoices have been accepted by Tenant.

               “Base Year. The term “Base Year” shall mean calendar year 2010.”

          7. Termination Option. As of the Effective date, Section 7 of the Second Amendment is deleted in its entirety and replaced with the following:

          “(a) Tenant shall have the one-time option to terminate the Lease effective as of October 31, 2014 (the “End Date”), by delivery of written notice of termination to Landlord at least twelve (12) months prior to the End Date; provided, however, that Tenant may only exercise such termination option if, prior to Tenant’s giving notice of such exercise, (i) Tenant has sold all or substantially all of the assets of its subsidiary, NextGen Healthcare Information Systems, a California corporation (“Next Gen”), in an arm’s length sale to a person or entity that is not an affiliate of either Tenant or Next Gen, or (ii) Tenant has requested and Landlord has advised Tenant in writing within twenty days from the date of Landlord’s receipt of Tenant’s request that Landlord is unable to provide expansion space for Tenant in the Building. Tenant’s notice exercising such termination option shall be irrevocable. As material consideration for the option to terminate herein set forth, Tenant shall deliver to Landlord at least ninety (90) days prior to the End Date Tenant’s good bank check for the “Termination Fee” (as defined below). In calculating the Termination Fee, it will be assumed the “Lease Costs” (as defined below) were financed at a fixed interest rate of ten percent (10) per annum with a seventy-two (72) month self-amortizing loan paid in seventy-two (72) equal monthly installments due on the first day of each calendar month, commencing on October 1, 2010 and the “Termination Fee” will be the principal balance that would remain outstanding under such loan following payment of the monthly installment owing for the calendar month in which the End Date occurs.

Notwithstanding anything to the contrary contained herein, at Landlord’s option, Tenant’s termination of the Lease pursuant to this Section 7 shall be ineffective if an Event of Default exists either at the time of Tenant’s exercise of its termination option or at the End Date. Failure of Tenant to timely exercise the option herein granted (“exercise” meaning both the giving of the requisite notice and the payment of the Termination Fee) shall constitute Tenant’s irrevocable waiver of such option.

          (b) Section 3.6 of the Lease is deleted in its entirety.”

          8. Right of First Refusal. As of the Effective Date, Section 14 of the Second Amendment is hereby deleted in its entirety and replaced with the following:

          “(a) From October 1, 2010 through September 30, 2012, provided no uncured Event of Default then exists hereunder, and further provided that Landlord shall have received a bona fide request for proposal with respect to all or any portion of the vacant space in the Building (the “Available Space”), Landlord shall first offer the Available Space to Tenant on the same terms and conditions (including, without limitation, length of Term and rate of Minimum Rent) as Landlord is leasing the Premises to Tenant. From October 1, 2012 through the end of the Term, provided no uncured Event of Default then exists hereunder, and further provided that Landlord shall have received a bona fide request for proposal with respect to all or any portion of the Available Space, Landlord shall first offer the Available Space to Tenant for the remainder of the Term, at a minimum rate of rent equal to the average minimum rate of rent that Landlord would propose to the unrelated third party who has requested a proposal, and otherwise on the same terms and conditions as Landlord would propose to the unrelated third party who has requested a proposal, reformulated for the remaining Term; for example, if Landlord would propose $10.00 per Rentable Square Foot for tenant improvements over a five (5) year term to the unrelated third party, but the remaining Term is only two (2) years, then Tenant would receive $4.00 per Rentable Square Foot for tenant improvements.

          (b) Landlord’s offer shall take the form of a written notice to Tenant setting forth the Rentable Area of the Available Space proposed to be leased, the date it is expected to be available, the proposed terms and conditions of lease (which, during the period from October 1, 2010 through September 30, 2012, shall be the same as the Lease) and a floor plan of the space in question. Tenant shall have ten (10) days after the date Tenant receives Landlord’s offer (“Landlord’s Offer”) to accept or decline the same without modification. In the event that Tenant does not accept Landlord’s offer in writing (and without modification) within ten (10) days after the date on which Tenant receives Landlord’s Offer, then Landlord shall be free to lease the Available Space to the party issuing the bona fide request for a proposal. In the event that Tenant accepts Landlord’s Offer in writing (without modification) within such time period, Landlord and Tenant shall have thirty (30) days from the date of Tenant’s acceptance in which to enter into a lease agreement for the Available Space or Landlord shall be free to lease the Available Space to any prospective tenant. Landlord and Tenant acknowledge and agree that if the Available Space subsequently becomes available again, Tenant shall have the same right of first refusal contained herein.”

          9. Ratification of Confession of Judgment.

               SECTION 17.2 OF THE LEASE PROVIDES FOR THE CONFESSION OF JUDGMENT AGAINST TENANT FOR MONEY AND FOR EJECTMENT.
