FIRST AMENDMENT TO OFFICE LEASE

     This First Amendment to Office Lease (the “First Amendment”), dated as of July 8, 2010, is made by and between Lakeshore Towers Limited Partnership Phase II, a California limited partnership (“Landlord”), and Quality Systems, Inc., a California corporation (“Tenant”).

RECITALS

     A. Landlord and Tenant entered into that certain Lease dated as of September 18, 2007 (the “Existing Lease”) covering those certain Premises situated in that certain office building located at 18111 Von Karman Avenue, Irvine, California, within the project commonly known as “Lakeshore Towers,” as more particularly described in the Existing Lease.

     B. Landlord and Tenant mutually desire to enter into this First Amendment in order to amend the Existing Lease to, among other things, extend the Lease Term and modify the square footage of the Premises (the Existing Lease, as amended by this First Amendment, the “Lease”).

     FOR VALUABLE CONSIDERATION, the receipt and adequacy of which is hereby acknowledged, Landlord and Tenant agree as follows:

1. Defined Terms. The meaning of certain defined terms in the Existing Lease shall be modified as follows:

     1.1 Premises. Effective as of the Completion Date (as defined below), the term “Premises” shall mean approximately 38,955 rentable square feet (34,335 usable square feet) of space consisting of:

          1.1.1. approximately 15,018 rentable square feet (12,795 usable square feet) located on the sixth floor of the Building and commonly known as Suite 600 (“Sixth Floor Premises”); and

          1.1.2. the entire seventh floor of the Building consisting of approximately 23,937 rentable square feet (21,540 usable square feet) and commonly known as Suite 700 (“Seventh Floor Premises”).

          The Premises are shown on pages 1 and 2 of Exhibit A to this First Amendment. The rentable square footage of each of the Sixth Floor Premises and Seventh Floor Premises was calculated pursuant to BOMA by Stephenson Systems on February 4, 2009 (“2009 Stephenson Calculation”), and such calculations have been provided to Tenant. Landlord and Tenant accept the 2009 Stephenson Calculation of 38,955 rentable square feet and 34,335 usable square feet for the Premises and 233,760 rentable square feet for the Building as final. Notwithstanding the foregoing, Base Rent calculations from and after the Completion Date through May 31, 2013 pursuant to Sections 1.2(i), (ii) and (iii) below shall be based on a total of 38,777 rentable square feet.

     1.2 Base Rent. From and after the Completion Date, “Base Rent” shall be as follows:

               (i) From and after the Completion Date through May 31, 2013, “Base Rent” for 23,759 rentable feet of the Premises shall be as follows:

               (iii) From and after June 1, 2013, “Base Rent” for the entire Premises (38,955 rentable square feet) shall be as follows and subpart (ii) next above shall be of no force or effect:

										Annual
						Monthly				Rental Rate

In connection with fixing the various time periods for payment of Base Rent pursuant to subparts (ii), (iii) and (iv) next above, Landlord and Tenant agree as follows:

     (x) In the event the Completion Date is not the first day of a calendar month, the period of the Completion Date through Month 22 shall be the month in which the Completion Date occurs plus the following twenty-two (22) calendar months.

     (y) The exact dates for Base Rent periods pursuant to subparts (ii) and (iii) above shall be confirmed pursuant to Section 12 below when the Completion Date has occurred.

     (z) Tenant and Landlord acknowledge that depending on the Completion Date, certain of the Base Rent periods set forth in subparts (ii) and (iii) above may be inapplicable.

Tenant shall pay to Landlord the first month’s Base Rent in the amount of Thirty-One Thousand Eight Hundred Thirty-Eight and 16/100 Dollars ($31,838.16) for the Seventh Floor Premises upon execution of this First Amendment by Tenant.

Notwithstanding the foregoing, Tenant may apply up to One Hundred Fifty-Five Thousand Eight Hundred Twenty and no/100 Dollars ($155,820.00) (which is Four Dollars ($4.00) multiplied by 38,955 which is the rentable square feet of the Premises) of the Tenant Improvement Allowance (as defined below) to Base Rent so long as:

LAKESHORE TOWERS BUILDING III
[Quality Systems, Inc.]

	(a)		Prior to August 31, 2011, Tenant advises Landlord in writing of the amount of the Tenant Improvement Allowance Tenant wishes to apply to Base Rent, which such amount will be applied to the Base Rent that is due immediately after the date such notice was given, but in no event sooner than thirty (30) days after the date of such notice; and
	(b)		at the time of such request, Tenant is not in default under this Lease and no event has occurred which, after notice or lapse of time, would be an event of default under this Lease.

     1.3 Lease Expiration Date. Effective as of the date hereof, “Lease Expiration Date” shall mean (i) if the Completion Date is the first day of a calendar month, the last day of the seventieth (70th) calendar month following the Completion Date, or (ii) if the Completion Date is other than the first day of a calendar month, the last day of the seventieth (70th) calendar month following the calendar month in which the Completion Date occurs. By way of example, if the Completion Date occurs on October 1, 2010, the Lease Expiration Date shall be July 31, 2016. By way of further example, if the Completion Date occurs on October 15, 2010, the Lease Expiration Date shall be August 31, 2016.

     1.4 Base Year. Effective as of the Completion Date, “Base Year” shall mean calendar year 2010. In connection with the modification of the Base Year, no Additional Rent on account of Operating Expenses and Tax Expenses shall be payable for the period of the Completion Date through the day immediately preceding the first (1st) anniversary of the Completion Date.

     1.5 Lease Term. Effective as of the date hereof, “Lease Term” shall mean the period of May 27, 2008 through the Lease Expiration Date.

     1.6 Tenant’s Share. Effective as of the Completion Date, “Tenant’s Share” shall mean sixteen and sixty-six one hundredths percent (16.66%). Such Tenant’s Share is calculated on the basis of the 2009 Stephenson Calculation.

     1.7 Completion Date. Effective as of the date hereof, “Completion Date” shall have the meaning set forth at Section 5.1 of the Work Letter (as defined below) attached hereto (i.e., “Completion Date” shall mean the date which is seven (7) days following the date on which the Tenant Improvements on the Seventh Floor Premises are substantially complete).

2. Tax Increase Protection. If during the period of the Completion Date through the day preceding the fifth (5th) anniversary of the Completion Date (“Tax Reassessment Protection Period”), any sale, refinancing or change in ownership of the Building is consummated and, as a result, all or part of the Building is reassessed (a “Reassessment”) for real estate tax purposes by the appropriate governmental authority under the terms of Proposition 13, the following shall apply:

               (i) For purposes of this Section 3, the term “Tax Increase” shall mean that portion of the Tax Expenses as calculated immediately following the Reassessment that is attributable solely to the Reassessment. Accordingly, a Tax Increase shall not include any portion of the Tax Expenses, as calculated immediately following Reassessment, that is:

                    (1) Attributable to the assessed value as of January 1, 2011 of the Building, the Base Building, or the tenant improvements located in the Building;

                    (2) Attributable to assessments pending immediately before the Reassessment that were conducted during, and included in, that Reassessment or that were otherwise rendered unnecessary following the Reassessment; or

                    (3) Attributable to the annual inflationary increase in real estate taxes.

               (ii) Tenant shall not be obligated to pay the Tax Increase Protection Amount (as defined below) of any Tax Increase due to the first Reassessment for the twelve (12) months following the date of Reassessment.

LAKESHORE TOWERS BUILDING III
[Quality Systems, Inc.]

     The “Tax Increase Protection Amount” shall be calculated as follows:

Period in which
the Reassessment Occurs		Tax Increase Protection
Completion Date through the day preceding the first anniversary of the Completion Date		1.00 x Tax Increase
First anniversary of the Completion Date through the day preceding the second anniversary of the Completion Date		0.8 x Tax Increase
Second anniversary of the Completion Date through the day preceding the third anniversary of the Completion Date		0.6 x Tax Increase
Third anniversary of the Completion Date through the day preceding the fourth anniversary of the Completion Date		0.4 x Tax Increase
Fourth anniversary of the Completion Date through the day preceding the fifth anniversary of the Completion Date		0.2 x Tax Increase

     By way of example, assume the Completion Date is October 15, 2010 in the event of a Reassessment resulting in a Tax Increase of One Hundred Thousand Dollars ($100,000) effective February 1, 2012, (i) the Tax Increase Protection would be available during the period of February 1, 2012 through January 31, 2013 and (ii) the Tax Increase Protection Amount would equal Eighty Thousand Dollars ($80,000) (i.e., 0.8 x $100,000 = $80,000).

     Notwithstanding the foregoing, Landlord, in its sole discretion, may terminate the Tax Increase protection at any time by paying Tenant an amount equal to the then present value of the Tax Increase Protection Amount calculated on the basis of a discount rate of eight percent (8%) per year and, in the event that there is less than twelve (12) months remaining on the Tax Increase protection, prorating such amount.

     Landlord and Tenant agree and acknowledge that the Tax Increase protection shall only apply to the first Reassessment occurring during the Tax Increase Protection Period and not to any subsequent tax reassessment occurring during the Tax Increase Protection Period.

3. Right of First Offer.

     3.1 Current First Offer Rights. Effective as of the date of this First Amendment, Section 1.4 of the Existing Lease is hereby deleted in its entirety.

     3.2 Right of First Offer. Landlord hereby grants to Quality Systems, Inc. (the “Original Tenant”), a right of first offer with respect to any space on the fourth (4th), fifth (5th) and sixth (6th) floors of the Building (the “First Offer Space”). Notwithstanding the foregoing, (i) such first offer right of Tenant shall commence only following the expiration or earlier termination of (A) that certain lease between Landlord and City National Bank and (B) that certain lease between Landlord and Pepperdine University (items (A) and (B), collectively, the “Superior Leases”, including any renewal or extension of such Superior Leases, provided such renewal or extension is pursuant to an express written provision in such Superior Lease, but regardless of whether any such renewal or extension is consummated strictly pursuant to the terms of such express written provisions, or pursuant to a lease amendment or a new lease, and (ii) such first offer right shall be subordinate and secondary to all rights of expansion, first refusal, rights of first offer or similar rights previously granted to the tenants of the Superior Leases (the rights described in items (i) and (ii) above to be known collectively as “Superior Rights”). Tenant’s Right of First Offer shall be on the terms and conditions set forth in this Section 3.

LAKESHORE TOWERS BUILDING III
[Quality Systems, Inc.]

          3.2.1. Procedure for Offer. Landlord shall notify Tenant (the “First Offer Notice”) from time to time when Landlord determines that marketing for any portion of the First Offer Space will commence because such portion of the First Offer Space shall become available for lease to third parties, provided that no holder of a Superior Right wishes to lease such space. Pursuant to such First Offer Notice, Landlord shall offer to lease to Tenant the then available First Offer Space. The First Offer Notice shall describe the space so offered to Tenant, shall set forth the date (“Anticipated First Offer Date”) upon which Landlord anticipates that the First Offer Space shall become available for lease to third parties (subject to any holdover of any then existing tenant).

          3.2.2. Procedure for Acceptance. During the five (5) business day period following receipt of the First Offer Notice, Landlord and Tenant shall meet and negotiate in good faith in an attempt to reach an agreement with respect to rent, length of lease, tenant improvement allowance, and other terms and conditions for the lease by Tenant from Landlord of the First Offer Space (if Tenant elects to lease the First Offer Space, such election shall be with respect to all of the First Offer Space offered by Landlord to Tenant at any particular time, and Tenant may not elect to lease only a portion thereof). If Landlord and Tenant are unable to agree upon the terms and conditions for Tenant’s lease of the First Offer Space during such five (5) business day period, Landlord may lease the First Offer Space to any other person or entity on such terms and conditions as are acceptable to Landlord and Tenant shall have no further rights with respect to such First Offer Space.

          3.2.3. Construction In First Offer Space. Tenant shall lease the First Offer Space in its “as is” condition (except to the extent an improvement allowance is agreed upon by Landlord and Tenant during negotiations as contemplated at Section 3.2.2 above).

          3.2.4. Amendment to Lease. If Tenant and Landlord reach agreement on Tenant’s lease of the First Offer Space as set forth herein, Landlord and Tenant shall within fifteen (15) days after such agreement execute a lease for such First Offer Space or an amendment to this Lease adding such First Offer Space to the Premises upon the terms and conditions agreed upon by Landlord and Tenant.

          3.2.5. Delivery of First Offer Space/Commencement of Rent. If Tenant timely and validly exercises the Right of First Offer, Landlord shall deliver the First Offer Space to Tenant on the Anticipated First Offer Date or, if delivery on such date is not possible, on a date mutually acceptable to Landlord and Tenant. The date of delivery of the First Offer Space to Tenant is referred to herein as the “First Offer Delivery Date”. At least thirty (30) days prior to the First Offer Delivery Date, Landlord shall provide Tenant with written notice of the estimated First Offer Delivery Date. Landlord shall not be liable to Tenant or otherwise be in default hereunder if Landlord is unable to deliver the First Offer Space to Tenant on the projected First Offer Delivery Date due to the failure of any other tenant to timely vacate and surrender to Landlord the First Offer Space or any portion of it.

     3.3 First Offer Right Personal to Original Tenant and Affiliates. The rights and benefits afforded Tenant with respect to the right of first offer (as set forth in this Section 3) are personal to Original Tenant and any Affiliate of Original Tenant which has assumed all of the obligations of Tenant under the Lease and may be exercised only by Original Tenant or such Affiliate if Original Tenant or such Affiliate occupies all of the Premises as of the date of the First Offer Notice.

4. Term Extension Option.

     4.1 Option to Extend. Section 2.2 of the Existing Lease remains in full force and effect except that references to “initial Lease Term” shall mean the “Lease Term” as amended herein.

     4.2 Rights Personal to Original Tenant and Affiliates. The rights and benefits afforded Tenant with respect to the option to extend the Lease Term (as set forth in this Section 4), are personal to Original Tenant and any Affiliate of Original Tenant which has assumed all of the obligations of Tenant under the Lease and may be exercised only by Original Tenant or such Affiliate.

5. Sixth Floor Return Space and Reduction Space.

     5.1 Sixth Floor Return Space. Tenant shall continue to lease through the day preceding the Completion Date pursuant to the terms of the Lease that portion of the Premises located on the sixth floor of the Building and consisting of approximately 8,919 rentable square feet as shown on page 3 of Exhibit A hereto (the “Return Space”). Tenant shall surrender possession of the Return Space to Landlord on the day preceding the Completion Date in the condition required by the Lease.

     5.2 Reduction Space. Notwithstanding anything in this First Amendment to the contrary, Landlord hereby grants Tenant a one time right to reduce the size of the Sixth Floor Premises by up to 15,018 rentable square feet effective on the fourth anniversary of the Completion Date, so long as written notice of such election to reduce (“Reduction Notice”) is delivered to Landlord on or before the date which is 270 days preceding the fourth anniversary of the Completion Date. The Reduction Notice shall identify the area on the Sixth Floor Premises which is the subject of the reduction (“Reduction Space”) and Tenant shall return possession of the Reduction Space to Landlord on the fourth anniversary of the Completion Date. In connection with any such Reduction Space:

               (i) Tenant shall reimburse Landlord for the cost of demising the remaining portion of the Sixth Floor Premises (if any) from the Reduction Space and performing any common area corridor work that is necessary or desirable in connection therewith.

               (ii) If the Reduction Space is less than all of the Sixth Floor Premises, the Reduction Space must, in Landlord’s reasonable judgment, be in a configuration that is readily leasable to third parties and in compliance with applicable law with respect to, among other things, egress and ingress to the Reduction Space.

               (iii) As a condition to the effectiveness of Tenant’s Reduction Notice, no later than 270 days preceding the fourth anniversary of the Completion Date, Tenant shall pay to Landlord an amount equal to the principal amount outstanding as of the fourth anniversary of the Completion Date, pursuant to a hypothetical loan made as of the Completion Date on the following terms and conditions: principal amortized on the basis of the seventy-one (71) month loan term, interest accruing at eight percent (8%) per year, and an original principal amount which is the sum of (1) Forty-Six and 64/100 Dollars ($46.64) multiplied by the Reduction Space rentable square footage, plus (2) the Improvement Allowance allocable to the Reduction Space, plus (3) the Brokers’ Commission (as defined below) allocable to the Reduction Space.

               (iv) Nothing herein relieves Tenant’s obligations under the Lease with respect to the condition of the Reduction Space when returned to Landlord.

               (v) Base Rent, Tenant’s Share and the number of parking spaces shall be proportionately modified to reflect such reduction, and such modifications shall be memorialized in a written amendment to the Lease to be prepared by Landlord and executed by Landlord and Tenant within fifteen (15) days after the date that Tenant has received for review an amendment complying with the terms of this Section 5.2(v).

     5.3 Rights Personal to Original Tenant and Affiliates. The rights and benefits afforded Tenant with respect to the Reduction Space as set forth in this Section 5 are personal to Original Tenant and any Affiliate of Original Tenant which has assumed all of the obligations of Tenant under the Lease and may be exercised only by Original Tenant or such Affiliate.

6. Non-Transfers. Section 14.6 of the Lease is hereby deleted in its entirety and the following inserted in its place and stead:

     Notwithstanding anything to the contrary contained in this Article 14, an assignment or subletting of all or a portion of the Premises to an entity which is controlled by, controls, or is under common control with, Tenant or the resultant entity of a merger, reorganization or reconstitution of Tenant (an “Affiliate”), shall not be deemed a Transfer under this Article 14, provided that (i) Tenant notifies Landlord of any such assignment or sublease and promptly supplies Landlord with any documents or information reasonably requested by Landlord regarding such assignment or sublease or such affiliate; (ii) such assignment or sublease is not a subterfuge by Tenant to avoid its

LAKESHORE TOWERS BUILDING III
[Quality Systems, Inc.]

obligations under this Lease; and (iii) in the case of an assignment of this Lease, the tangible net worth of such Affiliate (i.e., total assets less the sum of (i) total liabilities plus (ii) intangible assets (e.g., goodwill, intellectual property, etc.)) is not less than One Hundred Eighty-Eight Million Two Hundred Eighty-Nine Thousand and no/100 Dollars ($188,289,000.00). “Control,” as used in this Section 14.6, shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management and policies of a person or entity, whether by the ownership of voting securities, by contract or otherwise.

7. Standard Signage. In addition to Tenant’s signage rights under the Existing Lease, Tenant shall have the rights set forth in this Section 7.

     7.1 Entry Door Signage. If Tenant maintains an entry door on the Sixth Floor Premises, Tenant’s identifying signage on such entry door(s) shall be provided by Landlord, at Tenant’s cost, and such signage shall be comparable to that used by Landlord for other similar floors in the Building and shall comply with Landlord’s then-current Building standard signage program. Tenant may maintain its current signage in the elevator lobby of the sixth floor of the Building and similar signage in the elevator lobby of the seventh floor of the Building; provided, however, such signage shall not be exclusive and Landlord may install other signage in such elevator lobby.

     7.2 Tenant’s Right to Exterior Building Eyebrow Sign.

          7.2.1. Tenant’s Sign. Subject to Section 7.2.3 below, Tenant shall have the exclusive right to display its name or its logo (QSI) on an “eyebrow” sign at one of the locations on the Building as shown on Exhibit B attached hereto (such locations are referred to as “Proposed Sign A Location” and “Proposed Sign B Location” in Exhibit B) or at an alternative location on the Building selected by Tenant which alternative location shall be subject to Landlord’s approval, which approval may be withheld in Landlord’s sole and absolute discretion (“Tenant’s Sign”). Tenant’s Sign must:

               (i) Comply with all applicable governmental laws, statutes, regulations, rules, codes and ordinances;

               (iii) Have been approved in advance by all appropriate governmental agencies;

Failure by Landlord to advise Tenant in writing of its disapproval of Tenant’s Sign within ten (10) days after receipt of Tenant’s written request for approval shall be deemed approval by Landlord; and

               (v) Comply with all instruments recorded or unrecorded against the Project.

          7.2.2. Tenant’s Sign Installation. Installation of Tenant’s Sign shall be in accordance with the procedures and requirements of Article 8 of the Lease, except to the extent in conflict with this Section 7.

Tenant’s right to maintain its name on the Monuments shall be subject to the following requirements:

The foregoing may be changed by Landlord, in its reasonable discretion in consultation with Tenant.

               (iv) Tenant shall pay to Landlord, from time to time and within thirty (30) days after written demand, Tenant’s proportionate share of all expenses incurred by Landlord that are attributable (A) to the insurance, lighting (if applicable), maintenance, and repair of a Monument during the period of time that Tenant’s name is on such Monument or (B) removal of Tenant’s name from a Monument. Tenant’s portion of such expenses shall be calculated by Landlord by dividing such expenses among Tenant and Project occupants that have signs on the Monument in question in proportion to the Monument surface and as used by each in relation to the surface area used by all.

8. Parking. Effective as of the Completion Date, Tenant’s rights to parking spaces as set forth at Section 9 of the Summary shall terminate.

9. Prohibited Uses. In addition to the provisions of Section 5.2 of the Existing Lease, Tenant shall not use the Premises or permit the Premises to be used for a banking branch operation.

12. Confirmation of Completion Date and Other Lease Terms. Upon determination of the Completion Date and at any other time during the Lease Term, Landlord may deliver to Tenant a notice in the form as set forth in Exhibit F, attached hereto, as a confirmation only of the information set forth therein. Tenant shall execute and return to Landlord such notice within ten (10) days of receipt thereof.

13. Brokers. Tenant warrants and represents that it has not dealt with any real estate broker, agent, sales person or finder in connection with this Lease or its negotiation except for Grubb & Ellis Company (“Tenant’s Broker”) and Cushman & Wakefield of California, Inc. (“Landlord’s Broker”). Tenant shall indemnify and hold Landlord, its agents and employees harmless from any costs, expense or liability (including costs of suit and reasonable attorneys’ fees) for any compensation, commission or fees claimed by any other real estate broker, agent, sales person, finder or other entity claiming through Tenant in connection with this Lease or its negotiation. Landlord agrees to pay to Tenant’s Broker a commission equal to (i) four percent (4%) of the total Base Rent to be paid to Landlord during the sixty (60) month period following the Completion Date plus (ii) two percent (2%) of the total Base Rent to be paid to Landlord during months 61 through 71 following the Completion Date, plus (iii) Twenty Three Thousand Nine Hundred Thirty-Seven Dollars ($23,937.00) (which is One Dollar ($1.00) multiplied by the rentable square footage (23,937) of the Seventh Floor Premises). Notwithstanding the foregoing, no commission shall be paid to Tenant’s Broker with respect to the 23,759 rentable square feet during the period from the Completion Date through May 31, 2013. The commission payable to Tenant’s Broker shall be due fourteen (14) days following the execution and delivery of this First Amendment by Landlord and Tenant so long as Tenant is not then in default under the Lease. For purposes of such payment, Tenant’s Broker’s commission shall be calculated on the basis of a September 1, 2010 Completion Date.

(Landlord Build)

     This Work Letter shall set forth the terms and conditions relating to the construction of the tenant improvements in the Premises. This Work Letter is essentially organized chronologically and addresses the issues of the construction of the Premises, in sequence, as such issues will arise during the actual construction of the Premises. All references in this Work Letter to Articles or Sections of “this Lease” shall mean the relevant portion of Articles 1 through 28 of the Office Lease as amended by the First Amendment to which this Work Letter is attached as Exhibit E and of which this Work Letter forms a part, and all references in this Work Letter to Sections of “this Work Letter” shall mean the relevant portion of Sections 1 through 6 of this Work Letter. All references in this Work Letter to the “Premises” shall be deemed to refer to the Sixth Floor Premises and Seventh Floor Premises.

SECTION 1

DELIVERY OF THE PREMISES

     Tenant acknowledges that Tenant has thoroughly examined the Premises and Tenant shall accept the Premises from Landlord in their presently existing, “as-is” condition as of the date of this First Amendment.

SECTION 2

TENANT IMPROVEMENTS

     2.1 Tenant Improvement Allowance. Tenant shall be entitled to a one-time tenant improvement allowance (the “Tenant Improvement Allowance”) in the amount of Four Hundred Sixty-Seven Thousand Four Hundred Sixty and no/100 Dollars ($467,460.00) (which is Twelve Dollars ($12.00) multiplied by 38,955 which is the rentable square feet of the Premises) for the costs relating to the initial design and construction of Tenant’s improvements which are permanently affixed to the Premises (the “Tenant Improvements”).

     2.2 Disbursement of the Tenant Improvement Allowance. Except as otherwise set forth in this Work Letter, the Tenant Improvement Allowance shall be disbursed by Landlord (each of which disbursements shall be made pursuant to Landlord’s disbursement process) for costs related to the construction of the Tenant Improvements and for the following items and costs (collectively, the “Tenant Improvement Allowance Items”) and no portion of the Tenant Improvement Allowance, if any, remaining after the completion of the Tenant Improvements shall be available for use by Tenant:

               (i) payment of the fees of the Architect/Space Planner (as defined below) and the Engineers (as defined below);

               (ii) the cost of any changes in the Base Building when such changes are required by the Construction Documents;

               (iii) the cost of any changes to the Construction Documents or Tenant Improvements required by Code;

EXHIBIT E
Page 1

               (v) a portion of the costs of the tenant demising walls and public corridor walls and materials, if any, as designated by Landlord.

Landlord shall not charge a construction management fee for construction of the Tenant Improvements. Notwithstanding anything herein to the contrary, Tenant may elect to use up to One Hundred Thirty-Seven Thousand Three Hundred Forty and no/100 Dollars ($137,340.00) (which is Four Dollars ($4.00) multiplied by 34,335, the usable square footage of the Premises) of the Tenant Improvement Allowance for costs incurred by Tenant in connection with moving into the Seventh Floor Premises, for furniture to be used in the Premises and for telephone cabling and data cabling for the Premises. To the extent of available from the Tenant Improvement Allowance, upon presentation of evidence reasonably satisfactory to Landlord with respect to such costs, Landlord shall provide such reimbursement to Tenant within ten (10) business days of receipt of such reasonably satisfactory evidence.

In addition to the Tenant Improvement Allowance, Landlord shall contribute an amount not to exceed Five Thousand One Hundred Fifty and 25/100 Dollars ($5,150.25) (which is $0.15 multiplied by 34,335 which is the usable square footage of the Premises) towards the cost of a test fit sufficient to prepare preliminary pricing for the Tenant Improvements to be prepared by HHendy Associates.

Landlord and Tenant acknowledge that Tenant will remain in possession of the Sixth Floor Premises during construction of the Tenant Improvements. Landlord, Tenant and the Contractor (as defined below) shall cooperate so that Tenant’s occupancy of the Sixth Floor Premises does not interfere with construction of the Tenant Improvements and such construction does not adversely impact Tenant’s operations on the Sixth Floor Premises. Notwithstanding the foregoing, if construction of the Tenant Improvements must be conducted after normal Business Hours in order to accommodate Tenant’s operations, any additional cost shall be paid by Tenant upon Landlord’s request as an Over-Allowance Amount (as defined below).

     2.3 Building Standards. Landlord has established specifications for the Building standard components to be used in the construction of the Tenant Improvements in the Premises (the “Building Standards”). The quality of Tenant Improvements shall be equal to or of greater quality than the quality of the Building Standards, provided that Landlord may, at Landlord’s option, require the Tenant Improvements to comply with certain Building Standards. Landlord may make changes to the Building Standards from time to time.

SECTION 3

CONSTRUCTION DOCUMENTS

     3.1 Selection of Architect/Space Planner/Construction Documents. Landlord shall retain (i) HHendy Associates (Kerry Wilson and Jennifer Walton) (the “Architect/Space Planner”) to prepare the Construction Documents and (ii) the engineering consultants designated by Landlord (the “Engineers”) to prepare all engineering working drawings and specifications relating to the structural, mechanical, electrical, plumbing, HVAC, lifesafety, and sprinkler work of the Tenant Improvements. The working drawings, specification and contract documents to be prepared by Architect/Space Planner and the Engineers hereunder shall be known collectively as the “Construction Documents.” All Construction Documents shall comply with the drawing format and specifications as determined by Landlord, and shall be subject to Landlord’s approval.

     3.4 Permits. The Final Construction Documents shall be approved by Landlord (the “Approved Construction Documents”) prior to the commencement of the construction of the Tenant Improvements. Landlord shall submit the Approved Construction Documents to the appropriate municipal authorities for all applicable building permits necessary to allow Contractor (as defined below) to commence and fully complete the construction of the Tenant Improvements (the “Permits”). No changes, modifications or alterations in the Approved Construction Documents may be made without the prior written consent of Landlord, provided that Landlord may withhold its consent, in its sole discretion, to any change in the Approved Construction Documents if such change would directly or indirectly delay the Substantial Completion of the Premises (as defined below).

     3.5 Time Deadlines.

Landlord shall require the Contractor to (i) solicit cost proposal bids from three (3) subcontractors for each of the major trades (electrical, mechanical and carpentry) and (ii) require the Contractor’s bid to include a pre-negotiated fee for general conditions. Upon selecting the Contractor, Landlord shall provide Tenant with a cost proposal (the “Cost Proposal”) from the Contractor in accordance with the Approved Construction Documents, which Cost Proposal shall include, as nearly as possible, the cost of all Tenant Improvement Allowance Items to be incurred in connection with the design (including, without limitation, all fees of the Architect/Space Planner and the Engineers and all other “soft costs”) and construction of the Tenant Improvements. If the Cost Proposal is equal to or less than the Tenant Improvement Allowance, Tenant shall be deemed to have approved the Cost Proposal upon receipt. If the Cost Proposal is greater than the Tenant Improvement Allowance, then Landlord shall cooperate with Tenant’s efforts to value engineer the Approved Construction Documents to reduce the amount of the Cost Proposal so long as achievement of a Completion Date of October 1, 2010 will not, in Landlord’s reasonable judgment, be jeopardized; provided, however, (i) any modification of the Approved Construction Documents as a result of Tenant’s value engineering efforts shall be subject to Landlord’s reasonable approval and (ii) if the efforts of Tenant to value engineer the Cost Proposal do not result in Tenant’s written approval of a revised Cost Proposal (as value engineered) by the date which is fifteen (15) business days following delivery of the original Cost Proposal to Tenant, then Tenant shall be deemed to have approved the original Cost Proposal. Upon Tenant’s approval or deemed approval of the original or revised Cost Proposal and, in the case of a revised Cost Proposal, approval by Landlord, Landlord shall be released by Tenant to (i) retain the Contractor and (ii) purchase the items set forth in the approved or deemed approved Cost Proposal and commence the

In the event that, after the Cost Proposal Delivery Date, any revisions, changes, or substitutions shall be made to the Construction Documents or the Tenant Improvements, any additional costs which arise in connection with such revisions, changes or substitutions or any other additional costs shall be paid by Tenant to Landlord immediately upon Landlord’s request as an addition to the Over-Allowance Amount.

          4.3.2 Landlord’s Retention of Contractor. Landlord shall independently retain Contractor, on behalf of Tenant, to construct the Tenant Improvements in accordance with the Approved Construction Documents and the Cost Proposal and Landlord shall supervise the construction by Contractor.
