$112,000,000.00                                        as of March 8, 2013    
(Dated)

For value received, the undersigned, herein called "Borrower," promises to pay to the order of THE NORTHWESTERN MUTUAL LIFE INSURANCE COMPANY, a Wisconsin corporation, who, together with any subsequent holder of this note (hereinafter, the "Note"), is hereinafter referred to as "Lender", at 720 E. Wisconsin Avenue, Milwaukee, WI 53202 or at such other place as Lender shall designate in writing, in coin or currency which, at the time or times of payment, is legal tender for public and private debts in the United States, the principal sum of ONE HUNDRED TWELVE MILLION DOLLARS or so much thereof as shall have been advanced from time to time plus interest on the outstanding principal balance at the rate and payable as follows:

Interest shall accrue from the date of advance until maturity at the rate of three and ninety-six hundreds percent (3.96%) per annum (the "Interest Rate").
Accrued interest only on the amount advanced shall be paid on the fifth day of the month following the date of advance ("Amortization Period Commencement Date") and on the fifth day of the following month and of each month thereafter until March 5, 2018.  On the fifth day of April, 2018 and on the fifth day of each month thereafter until maturity, installments of principal and interest shall be paid in the amount of $532,126.00.
Interest will be calculated assuming each month contains thirty (30) days and each calendar year contains three hundred sixty (360) days.  In the event of a partial month, however, interest for such partial month will be calculated based on the actual number of days the principal balance of this Note is outstanding in the month and the actual number of days in the calendar year.
Payments shall be made directly to Lender by electronic transfer of funds using the Automated Clearing House System.  All installments shall be applied first in payment of interest, calculated monthly on the unpaid principal balance, and the remainder of each installment shall be applied in payment of principal.  The entire unpaid principal balance plus accrued interest thereon shall be due and payable on April 5, 2023 (the "Maturity Date").

Provided Lender has no further obligation to advance principal under this Note to Borrower, beginning as of the date hereof, Borrower shall have the right, upon not less than ten (10) Business Days prior written notice, to prepay (on a Business Day only) this Note in full with a Prepayment Fee (as hereinafter defined); provided, however, that such notice must contain the anticipated date of prepayment.  If Borrower fails to prepay on, or within ten (10) Business Days before or after such anticipated date of prepayment, such failure shall be deemed to be a withdrawal of Borrower's notice of prepayment, and Borrower shall be required to submit another written notice of prepayment pursuant to the terms and conditions set forth in this Note if Borrower thereafter elects to prepay this Note.  This Prepayment Fee represents consideration to Lender for loss of yield and reinvestment costs and shall also be payable whenever prepayment occurs as a result of the application of Condemnation Proceeds as defined in the Lien Instrument (as hereinafter defined).  The Prepayment Fee shall be the greater of Yield Maintenance or one percent (1%) of the outstanding principal balance of this Note (the "Prepayment Fee").  The Prepayment Fee shall be calculated as of the Prepayment Fee Determination Date.

"Business Day" means any day other than a Saturday, a Sunday or a day on which:  (i) Lender is closed for business or (ii) the Federal Reserve Bank of New York is closed for business.

"Yield Maintenance" means the amount, if any, by which

		
	               (i)
	the present value on the Prepayment Fee Determination Date of the Then Remaining Payments determined by using the Periodic Discount Rate; exceeds

		
	               (ii)
	the outstanding principal balance of this Note (exclusive of all accrued interest) on the Prepayment Fee Determination Date.

"Prepayment Fee Determination Date" means

		
	(A)
	In the case of a voluntary prepayment, the date of the voluntary prepayment;

1

Exhibit-10.75

		
	(B)
	In the case of a prepayment following an acceleration of the Indebtedness (as hereinafter defined), the date of such acceleration;

		
	(C)
	In the case of a prepayment due to a condemnation:

		
	(1)
	involving the filing of a claim for the Prepayment Fee with the condemning authority or court of competent jurisdiction, the date of such filing; or

		
	(2)
	not involving the filing of a claim for the Prepayment Fee with the condemning authority or court of competent jurisdiction, the date of such prepayment;

		
	(D)
	In the case of Borrower becoming a debtor in a bankruptcy or other insolvency proceeding, the date of Lender's filing of its proof of claim in such proceeding.

"Then Remaining Payments" means payments in such amounts and at such times as would have been payable subsequent to the Prepayment Fee Determination Date (assuming no prepayment) in accordance with the terms of this Note.

"Periodic Discount Rate" means the rate which, when compounded monthly, equals the sum of the Applicable Percentage and the Treasury Rate. 

"Applicable Percentage" means 0.50%.

"Treasury Rate" means: 

		
	(A)
	The linearly interpolated yield, compounded semi-annually, of the two (2) most recently auctioned (on the run) non-callable U.S. Treasury bonds, notes or bills (other than inflation indexed (i.e., inflation protected) securities) issued by the United States Treasury having maturity dates equivalent or most nearly equivalent to the Average Life Date as reported (on-line or otherwise) by The Wall Street Journal one (1) Business Day prior to the Prepayment Fee Determination Date; or 

		
	(B)
	If the yields from (A) above are not available, the linearly interpolated yield, compounded semi-annually, of the two (2) Treasury Constant Maturity Series (other than inflation indexed (i.e., inflation protected) securities) having constant maturity dates equivalent or most nearly equivalent to the Average Life Date as reported, for the latest day for which such yields shall have been so reported, as of one (1) Business Day preceding the Prepayment Fee Determination Date, in Federal Reserve Statistical Release H.15 (or comparable successor publication); or 

		
	(C)
	If the yields from (A) and (B) above are not available, a rate comparable to what would have been calculated under clause (A) or (B) above, as reasonably determined by Lender.

To the extent that the source used in (A), (B) or (C) above updates treasury yield information during the day, Lender shall rely on the treasury yields reported prior to 12:00 Noon (Central Time) one (1) Business Day prior to the Prepayment Fee Determination Date.

"Average Life Date" means the date which is the Remaining Average Life from the Prepayment Fee Determination Date.

"Remaining Average Life" means the number of years (calculated to the nearest day) obtained by dividing:

Exhibit-10.75

Upon the occurrence of an Event of Default (as defined in the Lien Instrument) followed by the acceleration of the whole indebtedness evidenced by this Note, the payment of such indebtedness will constitute an evasion of the prepayment terms hereunder and be deemed to be a voluntary prepayment hereof and such payment will, therefore, to the extent not prohibited by law, include the Prepayment Fee required under the prepayment in full right recited above.

In the event of a partial prepayment of this Note for any reason contemplated in the Loan Documents (as defined in the Lien Instrument), the Prepayment Fee, if required, shall be an amount equal to the Prepayment Fee if this Note were prepaid in full, multiplied by a fraction, the numerator of which shall be the principal amount prepaid and the denominator of which shall be the outstanding principal balance of this Note immediately preceding the Prepayment Fee Determination Date with respect to such partial prepayment.

Notwithstanding the above and provided Borrower is not in default under any provision contained in the Loan Documents, this Note may be prepaid in full at any time, without a Prepayment Fee, during the last sixty (60) days of the term of this Note.

Notwithstanding anything herein or in the other Loan Documents to the contrary, in the event Lender elects to apply any insurance proceeds held by Lender to the prepayment of the indebtedness evidenced by this Note, no Prepayment Fee shall be required to be paid.

Borrower acknowledges and agrees that the Interest Rate hereunder shall be increased if certain financial statements and other reports are not furnished to Lender, all as described in more detail in the provision of the Lien Instrument entitled "Financial Statements".

This Note is secured by certain property (the "Property") in the City of Philadelphia, County of Philadelphia, Commonwealth of Pennsylvania described in a Mortgage and Security Agreement (the "Lien Instrument") of even date herewith executed by PHILADELPHIA PLAZA - PHASE II, LP, a Pennsylvania limited partnership to THE NORTHWESTERN MUTUAL LIFE INSURANCE COMPANY.

Upon the occurrence of an Event of Default (as defined in the Lien Instrument), the whole unpaid principal hereof and accrued interest shall, at the option of Lender, to be exercised at any time thereafter, become due and payable at once without notice, notice of the exercise of, and the intent to exercise, such option being hereby expressly waived.

UPON ANY SUCH EVENT OF DEFAULT, AND WHILE SUCH EVENT OF DEFAULT IS CONTINUING, BORROWER, FOR ITSELF, ITS SUCCESSORS AND ASSIGNS HEREBY AUTHORIZES THE PROTHONOTARY OR ANY ATTORNEY OF ANY COURT OF RECORD IN THE COMMONWEALTH OF PENNSYLVANIA TO APPEAR FOR BORROWER AND CONFESS JUDGMENT FOR THE WHOLE UNPAID PRINCIPAL AND ACCRUED INTEREST, TOGETHER WITH THE COSTS OF SUIT AND ATTORNEY'S FEES.  THE AUTHORITY HEREIN GRANTED TO CONFESS JUDGMENT SHALL NOT BE EXHAUSTED BY ANY EXERCISE THEREOF BUT SHALL CONTINUE FROM TIME TO TIME AND AT ALL TIMES UNTIL FULL PAYMENT OF ALL AMOUNTS DUE HEREUNDER.  

Initials     /s/ JAT        

Borrower also waives the right of inquisition on any real estate that may be levied upon under any judgment obtained on this Note, voluntarily condemns the same and authorizes the entry of such condemnation upon any Writ of Execution issued on said judgment, and agrees that said real estate may be sold under the same.  Borrower also waives and releases unto Lender and said attorney all errors, defects and imperfections whatsoever of a procedural nature in the entering of said judgment or any process or proceeding relating thereto.

All parties at any time liable, whether primarily or secondarily, for payment of indebtedness evidenced hereby, for themselves, their heirs, legal representatives, successors and assigns, respectively, expressly waive presentment for payment, notice of dishonor, protest, notice of protest, and diligence in collection; consent to the extension by Lender of the time of said payments or any part thereof; further consent that the real or collateral security or any part thereof may be released by Lender, without in any way modifying, altering, releasing, affecting, or limiting their respective liability or the lien of the Lien Instrument; and agree to pay reasonable attorneys' fees and expenses of collection in case this Note is placed in the hands of an attorney for collection or suit is brought hereon and any actual out of pocket attorneys' fees and expenses incurred by Lender to enforce or preserve its rights under any of the Loan Documents in any bankruptcy or insolvency proceeding; provided, however, such attorneys' fees or expenses shall not include any fees or expenses incurred by Lender's in-house counsel.

Exhibit-10.75

All amounts due Lender including principal and, to the extent permitted by applicable law, interest not paid when due (without regard to any notice and/or cure provisions contained in any of the Loan Documents), including principal becoming due by reason of acceleration by Lender of the entire unpaid balance of this Note, shall bear interest from the due date thereof until paid at the Default Rate.  "Default Rate" means the lower of a rate equal to the interest rate in effect at the time of the default as herein provided plus 5% per annum or the maximum rate permitted by law.

No provision of this Note shall require the payment or permit the collection of interest, including any fees paid which are construed under applicable law to be interest, in excess of the maximum permitted by law.  If any such excess interest is collected or herein provided for, or shall be adjudicated to have been collected or be so provided for herein, the provisions of this paragraph shall govern, and Borrower shall not be obligated to pay the amount of such interest to the extent that it is in excess of the amount permitted by law.  Any such excess collected shall, at the option of Lender, unless otherwise required by applicable law, be immediately refunded to Borrower or credited on the principal of this Note immediately upon Lender's awareness of the collection of such excess and no Prepayment Fee shall be required in the event such amount is credited on the principal.

Notwithstanding any provision contained herein or in the Lien Instrument to the contrary, if Lender shall take action to enforce the collection of the indebtedness evidenced hereby or secured by the Lien Instrument (collectively, the "Indebtedness"), its recourse shall, except as provided below, be limited to the Property or the proceeds from the sale of the Property and the proceeds realized by Lender in exercising its rights and remedies (i) under the Absolute Assignment (as defined in the Lien Instrument), (ii) under separate guarantees, if any, (iii) under any of the other Loan Documents (as defined in the Lien Instrument) and (iv) in any other collateral securing the Indebtedness.  If such proceeds are insufficient to pay the Indebtedness, Lender will never institute any action, suit, claim or demand in law or in equity against Borrower for or on account of such deficiency; provided, however, that the provisions contained in this paragraph

		
	               (i)
	shall not in any way affect or impair the validity or enforceability of the Indebtedness or the Lien Instrument; and

		
	               (ii)
	shall not prevent Lender from seeking and obtaining a judgment against Borrower, and Borrower shall be personally liable, for any deficiency to the extent of the Recourse Obligations.

"Recourse Obligations" means

(a) rents and other income from the Property received by Borrower or those acting on behalf of Borrower from and after the date of any default under the Loan Documents remaining uncured prior to the Conveyance Date (as hereinafter defined), which rents and other income have not been applied to the payment of principal and interest on this Note or to reasonable operating expenses of the Property;

(f) amounts in excess of any rents or other revenues collected by Lender from operation of the Property from and after acceleration of the Indebtedness following an Event of Default by Borrower until the Conveyance Date, which amounts are necessary (prior to any payment of interest or principal on the Indebtedness) to pay real estate taxes, special assessments and insurance premiums with respect to the Property (to the extent not previously deposited with Lender by Borrower pursuant to the provision of the Lien Instrument following the caption entitled "Deposits by Mortgagor"), and amounts required to fulfill Borrower's obligations as lessor under any leases of the Property, in each case, either paid by Lender and not reimbursed prior to, or remaining due or delinquent on the Conveyance Date;

"Valid Tender" means (i) a Tender and (ii) the passage of the Review Period, during which period, Borrower shall not create any consensual liens on the Property and Borrower shall not be or become a debtor in any bankruptcy proceeding or the subject of any other insolvency proceeding (other than a bankruptcy or other insolvency proceeding commenced by Lender or any of its affiliates).

"Review Period" means the period of time from the date of the Tender until the earlier of (i) sixty (60) days thereafter or (ii) the date of acceptance of the Tender by Lender or Lender's designee.

All personal property hereinabove described is hereinafter referred to as the "Personal Property".

If any of the Property is of a nature that a security interest therein can be perfected under the Uniform Commercial Code, this instrument shall constitute a security agreement and financing statement if permitted by applicable law and Mortgagor authorizes Mortgagee to file a financing statement describing such Property and, at Mortgagee's request, agrees to join with Mortgagee in the execution of any financing statements and to execute any other instruments that may be necessary or desirable, in Mortgagee's determination, for the perfection or renewal of such security interest under the Uniform Commercial Code.

Tenants Using Chlorinated Solvents.  Mortgagor agrees not to lease any of the Property, without the prior written consent of Mortgagee, to (i) dry cleaning operations that perform dry cleaning on site with chlorinated solvents or (ii) any other tenants that use chlorinated solvents on site in the operation of their businesses.

Business Restriction Representation and Warranty.  Mortgagor represents and warrants that each of Mortgagor, all persons and entities owning (directly or indirectly) an ownership interest in Mortgagor (not including the shareholders of Thomas Properties Group, L.P. ("TPG") or Brandywine Realty Trust ("BDN") or the OP Unit Holders (as hereinafter defined), provided such OP Unit Holders each individually own, directly or indirectly, less than a 10% ownership interest in Borrower), all guarantors of all or any portion of the Indebtedness, and all persons and entities executing any separate indemnity agreement in favor of Mortgagee in connection with the Indebtedness: (i) is not, and shall not become, a person or entity with whom Mortgagee is restricted from doing business with under regulations of the Office of Foreign Assets Control ("OFAC") of the Department of the Treasury (including, but not limited to, those named on OFAC's Specially Designated Nationals and Blocked Persons list) or under any statute, executive order (including, but not limited to, the September 24, 2001 Executive Order Blocking Property and Prohibiting Transactions With Persons Who Commit, Threaten to Commit, or Support Terrorism), or other governmental action; (ii) is not, and shall not become, a person or entity with whom Mortgagee is restricted from doing business under the International Money Laundering Abatement and Financial Anti-Terrorism Act of 2001 or the regulations or orders thereunder; and (iii) is not knowingly engaged in, and shall not knowingly engage in, any dealings or transaction or be otherwise associated with such persons or entities described in (i) and (ii) above.

Insurance.  Mortgagor agrees to keep the Property insured for the protection of Mortgagee and Mortgagee's wholly owned subsidiaries and agents in such manner, in such amounts and in such companies as Mortgagee may from time to time approve consistent with Condition 30 of the Commitment, and to keep the policies therefor, properly endorsed, on deposit with Mortgagee, or at Mortgagee's option, to keep evidence of insurance reasonably acceptable to Mortgagee evidencing all insurance coverages required hereunder on deposit with Mortgagee, which evidence shall reflect at least thirty (30) days notice of cancellation (except for 10 days notice of cancellation for non-payment of premium) to Mortgagee and shall list Mortgagee as the certificate holder or as a similar additional insured interest with Mortgagee's correct mailing address and the loan number assigned to the loan 339594; if Mortgagor requests Mortgagee to accept a different form of evidence, Mortgagee shall not unreasonably withhold, condition or delay its consent, provided, a copy of a standard mortgagee endorsement in favor of Mortgagee stating that the insurer shall provide at least thirty (30) days notice of cancellation (except for 10 days notice of cancellation for non-payment of premium) to Mortgagee accompanies such evidence.  Mortgagor shall furnish Mortgagee with renewals of all applicable insurance evidence no later than five (5) days after the actual insurance expiration date.

If the Property shall be damaged or destroyed, in whole or in part, by fire or other casualty, Mortgagor shall give prompt written notice thereof to Mortgagee.  Following the occurrence of a casualty, Mortgagor, regardless of whether insurance proceeds are available, shall promptly proceed to restore, repair, replace or rebuild the improvements on the Property to be of at least equal value and of substantially the same character as prior to such damage or destruction, all to be effected in accordance with applicable law.  All insurance loss proceeds from all property insurance policies whether or not required by Mortgagee (less expenses of collection) shall, at Mortgagee's option, be applied on the Indebtedness, except as otherwise specifically provided herein or in any other Loan document, whether due or not, or to the restoration of the Property, or be released to Mortgagor, but such application or release shall not cure or waive any default under any of the Loan Documents.  If Mortgagee elects to apply the insurance loss proceeds on the Indebtedness, no prepayment fee shall be due thereon.  Mortgagee acknowledges that the insurance coverage and companies reflected in the certificates of insurance delivered by Mortgagor to Mortgagee are acceptable to Mortgagee as of the date hereof.

Notwithstanding the foregoing provision, Mortgagee agrees that if the casualty occurs prior to the last year of the term of the Note, then the insurance loss proceeds (less expenses of collection) shall be applied to restoration of the Property to its condition prior to the casualty, subject to satisfaction of the following conditions:

		
	              (a)
	There is no existing Event of Default at the time of casualty.

3

Exhibit-10.76

		
	              (b)
	The casualty insurer has not denied liability for payment of insurance loss proceeds to Mortgagor as a result of any act, neglect, use or occupancy of the Property by Mortgagor or any tenant of the Property.

		
	              (c)
	Mortgagee shall be satisfied that all insurance loss proceeds so held, together with supplemental funds to be made available by Mortgagor, shall be sufficient to complete the restoration of the Property.  Any remaining insurance loss proceeds may, at the option of Mortgagee, be applied on the Indebtedness, whether or not due, or be released to Mortgagor.

		
	              (d)
	If required by Mortgagee, Mortgagee shall be furnished a satisfactory report addressed to Mortgagee from an environmental engineer or other qualified professional satisfactory to Mortgagee to the effect that no adverse environmental impact to the Property resulted from the casualty.

		
	              (e)
	Mortgagee shall release casualty insurance proceeds as restoration of the Property progresses provided that Mortgagee is furnished satisfactory evidence of the costs of restoration and if, at the time of such release, there shall exist no Monetary Default (as hereinafter defined) under the Loan Documents and no Non-Monetary Default (as hereinafter defined) with respect to which Mortgagee shall have given Mortgagor notice pursuant to the "Notice of Default" provision herein.  If a Monetary Default shall occur or Mortgagee shall give Mortgagor notice of a Non-Monetary Default, Mortgagee shall have no further obligation to release insurance loss proceeds hereunder unless such default is cured within the cure period set forth in the "Notice of Default" provision contained herein.  If the estimated cost of restoration exceeds $800,000.00, (i) the drawings and specifications for the restoration shall be approved by Mortgagee in writing prior to commencement of the restoration, and (ii) Mortgagee shall receive an administration fee equal to one percent (1%) of the cost of restoration.

		
	               (f)
	Prior to each release of funds, Mortgagor shall obtain for the benefit of Mortgagee an endorsement to Mortgagee's title insurance policy insuring Mortgagee's lien as a first and valid lien on the Property subject only to liens and encumbrances theretofore approved by Mortgagee.

		
	               (g)
	Mortgagor shall pay all reasonable costs and expenses incurred by Mortgagee, including, but not limited to, outside legal fees, title insurance costs, third‐party disbursement fees, third‐party engineering reports and inspections deemed necessary by Mortgagee.

		
	               (h)
	All reciprocal easement and operating agreements, if any, benefiting the Property shall remain in full force and effect between the parties thereto on and after restoration of the Property.

		
	               (i)
	Mortgagee shall be reasonably satisfied that Projected Debt Service Coverage of at least 1.25 will be produced from the leasing of space to tenants under Approved Leases (as hereinafter defined).

		
	               (j)
	All leases in effect at the time of the casualty with tenants who have entered into a non-disturbance and attornment agreement or similar agreement with Mortgagee shall remain in full force (except as such leases may have expired at the end of their terms) and Mortgagee shall be satisfied that restoration can be completed within a timeframe such that each tenant thereunder shall be obligated, or each such tenant shall have elected, to continue the lease term at full rental (subject only to abatement, if any, during any period in which the Property or a portion thereof shall not be used and occupied by such tenant as a result of the casualty).

"Approved Leases" means leases to (i) existing tenants with a remaining term of at least three (3) years or (ii) approved new tenants with leases satisfactory to Mortgagee for terms of at least three (3) years, to commence not later than sixty (60) days following completion of restoration.

For purposes of the preceding sentence, "debt service" means the greater of (x) debt service due under all such indebtedness during the first fiscal year following completion of the restoration of the Property or (y) debt service that would be due and payable during such fiscal year if all such indebtedness were amortized over 30 years (whether or not amortization is actually required) and if interest on such indebtedness were due as it accrues at the face rate shown on the notes therefor (whether or not interest payments based on such face rates are required).

Exhibit-10.76

"Projected Operating Income Available for Debt Service" means projected gross annual rent from the Approved Leases for the first full fiscal year following completion of the restoration of the Property less:

		
	(A)
	The operating expenses of the Property for the last fiscal year preceding the casualty and

(B)    the following:

		
	              (i)
	a replacement reserve for future capital improvements, tenant improvements, leasing commissions and structural items based on not less than $3.53 per square foot per annum;

		
	              (ii)
	the amount, if any, by which actual gross income during such fiscal period exceeds that which would be earned from the rental of 87.5% of the gross leasable area in the Property;

		
	              (iii)
	the amount, if any, by which the actual management fee is less than 3.0% of gross revenue during such fiscal period;

		
	              (iv)
	the amount, if any, by which the actual real estate taxes are less than $3,400,000.00 per annum; and

		
	              (v)
	the amount, if any, by which total operating expenses, excluding management fees, real estate taxes and replacement reserves, are less than $8,200,000.00 per annum.

All projections referenced above shall be calculated in a manner satisfactory to Mortgagee in its reasonable discretion.

Condemnation.  Mortgagor hereby assigns to Mortgagee (i) any award and any other proceeds resulting from damage to, or the taking of, all or any portion of the Property, and (ii) the proceeds from any sale or transfer in lieu thereof (collectively, "Condemnation Proceeds") in connection with condemnation proceedings or the exercise of any power of eminent domain or the threat thereof (hereinafter, a "Taking"); provided, however, Mortgagee agrees if the Condemnation Proceeds are less than the unpaid principal balance of the Note and such damage or Taking occurs prior to the last year of the term of the Note, such Condemnation Proceeds (less expenses of collection) shall be applied to restoration of the Property to its condition, or the functional equivalent of its condition prior to the Taking, subject to the satisfaction of the requirement that restoration or replacement of the improvements on the Land to their functional and economic utility prior to such damage or the Taking be possible, and subject to satisfaction of the following conditions:

		
	              (a)
	There is no existing Event of Default at the time of the Taking.

		
	              (b)
	Mortgagee shall be satisfied that all Condemnation Proceeds, together with supplemental funds to be made available by Mortgagor, shall be sufficient to complete the restoration of the Property.  Any remaining Condemnation Proceeds may, at the option of Mortgagee, be applied on the Indebtedness, whether or not due, or be released to Mortgagor.

		
	              (c)
	If required by Mortgagee, Mortgagee shall be furnished a satisfactory report addressed to Mortgagee from an environmental engineer or other qualified professional satisfactory to Mortgagee to the effect that no adverse environmental impact to the Property resulted from the Taking.

		
	              (d)
	Mortgagee shall release Condemnation Proceeds as restoration of the Property progresses provided that Mortgagee is furnished satisfactory evidence of the costs of restoration and if, at the time of such release, there shall exist no Monetary Default under the Loan Documents and no Non-Monetary Default with respect to which Mortgagee shall have given Mortgagor notice pursuant to the "Notice of Default" provision herein.  If a Monetary Default shall occur or Mortgagee shall give Mortgagor notice of a Non-Monetary Default, Mortgagee shall have no further obligation to release Condemnation Proceeds hereunder unless such default is cured within the cure period set forth in the "Notice of Default" provision contained herein.  If the estimated cost of restoration exceeds $400,000.00, (i) the drawings and specifications for the restoration shall be approved by Mortgagee in writing prior to commencement of the restoration, and (ii) Mortgagee shall receive an administration fee equal to one percent (1%) of the cost of restoration.

		
	              (e)
	Prior to each release of funds, Mortgagor shall obtain for the benefit of Mortgagee an endorsement to Mortgagee's title insurance policy insuring Mortgagee's lien as a first and valid lien on the Property subject only to liens and encumbrances theretofore approved by Mortgagee.

Exhibit-10.76

		
	               (f)
	Mortgagor shall pay all costs and expenses incurred by Mortgagee, including, but not limited to, outside legal fees, title insurance costs, third‐party disbursement fees, third‐party engineering reports and inspections deemed necessary by Mortgagee.

		
	               (g)
	All reciprocal easement and operating agreements, if any, benefiting the Property shall remain in full force and effect between the parties thereto on and after restoration of the Property.

		
	               (h)
	Mortgagee shall be reasonably satisfied that Projected Debt Service Coverage of at least 1.25 will be produced from the leasing of space to tenants under Approved Leases.

		
	               (i)
	All leases in effect at the time of the Taking with tenants who have entered into a non-disturbance and attornment agreement or similar agreement with Mortgagee shall remain in full force and Mortgagee shall be satisfied that restoration can be completed within a timeframe such that each tenant thereunder shall be obligated, or each such tenant shall have elected, to continue the lease term at full rental (subject only to abatement, if any, during any period in which the Property or a portion thereof shall not be used and occupied by such tenant as a result of the Taking).

Taxes and Special Assessments.  Mortgagor agrees to pay before delinquency all taxes and special assessments of any kind that have been or may be levied or assessed against the Property, this instrument, the Note or the Indebtedness, or upon the interest of Mortgagee in the Property, this instrument, the Note or the Indebtedness, and to procure and deliver to Mortgagee within 30 days after Mortgagee shall have given a written request to Mortgagor, the official receipt of the proper officer showing timely payment of all such taxes and assessments; provided, however, that Mortgagor shall not be required to pay any such taxes or special assessments if the amount, applicability or validity thereof shall currently be contested in good faith by appropriate proceedings and funds sufficient to satisfy the contested amount have been deposited in an escrow satisfactory to Mortgagee.

Personal Property.  With respect to the Personal Property, Mortgagor hereby represents, warrants and covenants as follows:

(a)    Except for the security interest granted hereby, Mortgagor is, and as to portions of the Personal Property to be acquired after the date hereof will be, the sole owner of the Personal Property, free from any lien, security interest, encumbrance or adverse claim thereon of any kind whatsoever.  Mortgagor shall notify Mortgagee of, and shall indemnify and defend Mortgagee and the Personal Property against, all claims and demands of all persons at any time claiming the Personal Property or any part thereof or any interest therein.

(b)    Except as otherwise provided above, Mortgagor shall not lease, sell, convey or in any manner transfer the Personal Property without the prior consent of Mortgagee.

(c)    Mortgagor is a limited partnership formed and existing under the laws of the Commonwealth of Pennsylvania and maintains its chief executive office at the address set forth above in this instrument.  Until the Indebtedness is paid in full, Mortgagor (i) shall not change its legal name without providing Mortgagee with thirty (30) days prior written notice; (ii) shall not change its chief executive office; and (iii) shall preserve its existence and shall not, in one transaction or a series of transactions, merge into or consolidate with any other entity.

(d)    At the request of Mortgagee, Mortgagor shall join Mortgagee in executing one or more financing statements and continuations and amendments thereof pursuant to the Uniform Commercial Code in form satisfactory to Mortgagee, and Mortgagor shall pay the cost of filing the same in all public offices wherever filing is deemed by Mortgagee to be necessary or desirable.  Mortgagor shall also, at Mortgagor's expense, take any and all other action requested by Mortgagee to perfect Mortgagee's security interest under the Uniform Commercial Code with respect to the Personal Property, including, without limitation, exercising Mortgagor's best efforts to obtain any consents, agreements or acknowledgments required of third parties to perfect Mortgagee's security interest in Personal Property consisting of deposit accounts, letter-of-credit rights, investment property, and electronic chattel paper.

Other Liens.  Mortgagor agrees to keep the Property and any Personal Property free from all other liens either prior or subsequent to the lien created by this instrument.  The (i) creation of any other lien on any portion of the Property or on any Personal Property, whether or not prior to the lien created hereby, (ii) assignment or pledge by Mortgagor of its revocable license to collect, use and enjoy rents and profits from the Property, or (iii) granting or permitting of a security interest in or other encumbrance on the direct or indirect ownership interests in Mortgagor, shall constitute a default under the terms of this instrument; except that upon written notice to Mortgagee, Mortgagor may proceed to contest in good faith and by appropriate proceedings any mechanics liens, tax liens or judgment liens with respect to the Property or any Personal Property described 

6

Exhibit-10.76

herein, provided funds sufficient to satisfy the contested amount have been deposited in an escrow account satisfactory to Mortgagee.

Indemnification, Duty to Defend and Costs, Fees and Expenses.  In addition to any other indemnities contained in the Loan Documents, Mortgagor shall indemnify, defend and hold Mortgagee harmless from and against any and all losses, liabilities, claims, demands, damages, costs and expenses (including, but not limited to, costs of title evidence and endorsements to Mortgagee's title insurance policy with respect to the Property and reasonable attorney fees and other costs of defense) of this trust which may be imposed upon, incurred by or asserted against Mortgagee, whether or not any legal proceeding is commenced with regard thereto, in connection with: (i) the enforcement of any of Mortgagee's rights or powers under the Loan Documents; (ii) the interpretation of any of the terms and conditions of the Loan Documents, (iii) the protection of Mortgagee's interest in the Property; or (iv) any accident, injury to or death of persons or loss of or damage to property occurring in, on or about the Property or on any sidewalk, curb, parking area, space or street located adjacent thereto.  If any claim or demand is made or asserted against Mortgagee by reason of any event as to which Mortgagor is obligated to indemnify or defend Mortgagee, then, upon demand by Mortgagee, Mortgagor, at Mortgagor's sole cost and expense, shall defend such claim, action or proceeding in Mortgagee's name, if necessary, by such attorneys as Mortgagee shall approve.  Notwithstanding the foregoing, Mortgagee may, in Mortgagee's sole discretion, engage its own attorneys to defend it or assist in its defense and Mortgagor shall pay the reasonable fees and disbursements of such attorneys; provided, however, Mortgagor shall not be obligated to pay any fees and disbursements to Mortgagee's in-house counsel.

Failure of Mortgagor to Act.  If Mortgagor fails to make any payment or do any act as herein provided, Mortgagee may, without obligation to do so, without notice to or demand upon Mortgagor and without releasing Mortgagor from any obligation hereof: (i) make or do the same in such manner and to such extent as Mortgagee may deem necessary to protect the security hereof, Mortgagee being authorized to enter upon the Property for such purpose; (ii) appear in and defend any action or proceeding purporting to affect the security hereof, or the rights or powers of Mortgagee; (iii) pay, purchase, contest or compromise any encumbrance, charge or lien which in the judgment of Mortgagee appears to be prior or superior hereto; and (iv) in exercising any such powers, pay necessary expenses, employ counsel and pay its reasonable fees.  Sums so expended and all losses, liabilities, claims, damages, costs and expenses required to be reimbursed by Mortgagor to Mortgagee hereunder shall be payable by Mortgagor immediately upon demand with interest from date of expenditure or demand, as the case may be, at the Default Rate (as defined in the Note).  All sums so expended or demanded by Mortgagee and the interest thereon shall be included in the Indebtedness and secured by the lien of this instrument.

Event of Default.  Any default by Mortgagor in making any required payment of the Indebtedness or any default in any provision, covenant, agreement, warranty or certification contained in any of the Loan Documents shall, except as provided in the two immediately succeeding paragraphs, constitute an "Event of Default".

Notice of Default.  A default in any payment required in the Note or any other Loan Document, whether or not payable to Mortgagee, (a "Monetary Default") shall not constitute an Event of Default unless Mortgagee shall have given a written notice of such Monetary Default to Mortgagor and Mortgagor shall not have cured such Monetary Default by payment of all amounts in default (including payment of interest at the Default Rate, as defined in the Note, from the date of default to the date of cure on amounts owed to Mortgagee) within five (5) Business Days (as hereinafter defined) after the date on which Mortgagee shall have given such notice to Mortgagor.

Any other default under the Note or under any other Loan Document (a "Non‐Monetary Default") shall not constitute an Event of Default unless Mortgagee shall have given a written notice of such Non‐Monetary Default to Mortgagor and Mortgagor shall not have cured such Non‐Monetary Default within thirty (30) days after the date on which Mortgagee shall have given such notice of default to Mortgagor (or, if the Non‐Monetary Default is not curable within such 30‐day period, Mortgagor shall not have diligently undertaken and continued to pursue the curing of such Non‐Monetary Default and deposited an amount sufficient to cure such Non‐Monetary Default in an escrow account satisfactory to Mortgagee).

In no event shall the notice and cure period provisions recited above constitute a grace period for the purposes of commencing interest at the Default Rate (as defined in the Note).

"Business Day" means any day other than a Saturday, a Sunday or a day on which: (i) Mortgagee is closed for business or (ii) the Federal Reserve Bank of New York is closed for business.

Appointment of Receiver.  Upon commencement of any proceeding to enforce any right under this instrument, including foreclosure thereof, Mortgagee (without limitation or restriction by any present or future law, without regard to the solvency or insolvency at that time of any party liable for the payment of the Indebtedness, without regard to the then value of the Property, whether or not there exists a threat of imminent harm, waste or loss to the Property and whether or not the same shall then be 

7

Exhibit-10.76

occupied by the owner of the equity of redemption as a homestead) shall have the absolute right to the appointment of a receiver of the Property and of the revenues, rents, profits and other income therefrom, and said receiver shall have (in addition to such other powers as the court making such appointment may confer) full power to collect all such income and, after paying all necessary expenses of such receivership and of operation, maintenance and repair of said Property, to apply the balance to the payment of any of the Indebtedness then due.

Foreclosure.  Upon the occurrence of an Event of Default, the entire unpaid Indebtedness shall, at the option of Mortgagee, become immediately due and payable for all purposes without any notice or demand, except as required by law, (ALL OTHER NOTICE OF THE EXERCISE OF SUCH OPTION, INCLUDING WITHOUT LIMITATION NOTICE OF THE INTENT TO ACCELERATE, BEING HEREBY EXPRESSLY WAIVED), and Mortgagee may, in addition to exercising any rights it may have with respect to the Personal Property under the Uniform Commercial Code of the jurisdiction in which the Property is located, institute proceedings in any court of competent jurisdiction to foreclose this instrument as a mortgage, or to enforce any of the covenants hereof, or Mortgagee may, to the extent permitted by applicable law (without limiting their rights under the foregoing provisions or otherwise), either personally or by agent or attorney in fact, enter upon and take possession of the Property and may manage, rent or lease the Property or any portion thereof upon such terms as Mortgagee may deem expedient, and collect, receive and receipt for all rentals and other income therefrom and apply the sums so received as hereinafter provided in case of sale.  Mortgagee is hereby further authorized and empowered, to the extent permitted by applicable law, as agent or attorney in fact, either after or without such entry, to sell and dispose of the Property en masse or in separate parcels (as Mortgagee may think best), and all the right, title and interest of Mortgagor therein, by advertisement or in any manner provided by applicable law, (MORTGAGOR HEREBY EXPRESSLY WAIVES ANY RIGHT TO A HEARING PRIOR TO SUCH SALE, TO THE EXTENT PERMITTED BY APPLICABLE LAW), and to issue, execute and deliver a deed of conveyance, all as then may be provided by applicable law; and Mortgagee, to the extent permitted by applicable law, shall, out of the proceeds or avails of such sale, after first paying and retaining all fees, charges, costs of advertising the Property and of making said sale, and attorneys' fees as herein provided, apply such proceeds to the Indebtedness, including all sums advanced or expended by Mortgagee or the legal holder of the Indebtedness, with interest from date of advance or expenditure at the Default Rate (as defined in the Note), rendering the excess, if any, as provided by law; such sale or sales and said deed or deeds so made shall be a perpetual bar, both in law and equity, against Mortgagor, the heirs, successors and assigns of Mortgagor, and all other persons claiming the Property aforesaid, or any part thereof, by, from, through or under Mortgagor.  The legal holder of the Indebtedness may purchase the Property or any part thereof, and it shall not be obligatory upon any purchaser at any such sale to see to the application of the purchase money.

Prohibition on Transfer/One-Time Transfer.  The present ownership and management of the Property is a material consideration to Mortgagee in making the loan secured by this instrument, and Mortgagor shall not (i) convey title to all or any part of the Property, (ii) enter into any contract to convey (land contract/installment sales contract/contract for deed) title to all or any part of the Property which gives a purchaser possession of, or income from, the Property prior to a transfer of title to all or any part of the Property ("Contract to Convey") or (iii) cause or permit a Change in the Proportionate Ownership (as hereinafter defined) of Mortgagor except as expressly permitted herein.  Any such conveyance, entering into a Contract to Convey or Change in the Proportionate Ownership of Mortgagor shall constitute a default under the terms of this instrument.

Notwithstanding the foregoing, (i) changes in the shareholders of TPG so long as TPG is publicly traded on a national public market exchange, (ii) changes in the shareholders of BDN so long as BDN is publicly traded on a national public market exchange, and (iii) changes in the OP Unit Holders shall not be deemed to be a Change in the Proportionate Ownership of Mortgagor, and Mortgagee's consent shall not be required for a Change in the Proportionate Ownership of Mortgagor resulting from changes in the shareholders of TPG or BDN so long as TPG or BDN is publicly traded on a national public market exchange or from changes in the OP Unit Holders.  Furthermore, the following transfers shall not constitute a Change in Proportionate Ownership of Mortgagor and shall not require Mortgagee's approval or consent (provided that Mortgagor shall promptly notify Mortgagee in writing of any such transfer and shall provide Mortgagee with reasonable evidence that the requirements below have been met):

		
	(i)

	(v)
	pursuant to written documentation prepared by and satisfactory to Mortgagee, the transferee assumes and the Creditworthy Party guarantees, all of the recourse obligations and liabilities of Mortgagor under the Loan Documents, whether arising prior to or after the date of the transfer of the Property, and Mortgagee receives a satisfactory enforceability opinion with respect thereto from counsel approved by Mortgagee; in no event, however, shall a non-consolidation opinion be required;

		
	(vi)
	the Creditworthy Party executes Mortgagee's then current forms of Guarantee and Guarantee of Recourse Obligations, the Creditworthy Party and the transferee execute Mortgagee's then current form of Environmental Indemnity Agreement, and Mortgagee receives a satisfactory enforceability opinion with respect to the foregoing from counsel approved by Mortgagee; in no event, however, shall a non-consolidation opinion be required;

		
	(vii)
	an environmental report on the Property which meets Mortgagee's then current requirements and is updated to no earlier than ninety (90) days prior to the date of transfer, is provided to Mortgagee at least thirty (30) days prior to the date of transfer and said report shall be satisfactory to Mortgagee at the time of transfer;

		
	(viii)
	Mortgagor (a) shall remain liable under the Environmental Indemnity Agreement dated of even date herewith, except for acts or occurrences after the date of transfer of the Property and (b) shall, except as provided in (a) above, be released from all obligations and liabilities under the Loan Documents;

	(xi)

10

Exhibit-10.76

If Mortgagor shall make a one‐time transfer of the Property pursuant to the above conditions, Mortgagee shall be paid a fee equal to one-half percent (0.5%) of the then outstanding balance of the Note at the time of transfer.  The fee shall be paid on or before the closing date of such one‐time transfer.  At the time of such transfer, no modification of the interest rate or repayment terms of the Note will be required. 

No subsequent transfers of the Property shall be allowed and no Change in the Proportionate Ownership of transferee shall be allowed without Mortgagee's prior written consent.  Notwithstanding the foregoing, Mortgagor and Mortgagee agree that the underlying ownership structure of a particular transferee may cause Mortgagee to determine that the definition of Change in the Proportionate Ownership of such transferee does not adequately address Mortgagee's underlying ownership concerns for such transferee, and accordingly, Mortgagee reserves the right to amend the definition of Change in the Proportionate Ownership as it applies to a particular transferee.

"Debt Service Coverage" means a number calculated by dividing Net Income Available for Debt Service for a fiscal period by the debt service during the same fiscal period under all indebtedness (including the Indebtedness) secured by any portion of the Property.  For purposes of the preceding sentence, "debt service" means the actual debt service due under all indebtedness secured by any portion of the Property or by any ownership interests in Mortgagor, based upon an amortization schedule which is the shorter of the actual amortization schedule or 30 years (whether or not amortization is actually required) and, if an accrual loan, as if interest and principal on such indebtedness were due monthly.

"Net Income Available for Debt Service" means net income (prior to giving effect to any capital gains or losses and any extraordinary items) from the Property, determined in accordance with generally accepted accounting principles, for a fiscal period, plus (to the extent deducted in determining net income from the Property):

		
	               A)
	interest on indebtedness secured by any portion of the Property (or secured by a Subordinate Lien (as hereinafter defined) permitted under the Loan Documents) for such fiscal period;

		
	               B)
	depreciation, if any, of fixed assets at or constituting the Property for such fiscal period;

		
	               C)
	amortization, if any, of standard tenant finish expenditures at the Property (but specifically excluding the amortization of tenant finish expenditures by Mortgagor in excess of $60.00 per square foot for new tenants and $30.00 per square foot for renewal tenants (i.e., above standard tenant finishes)); and

		
	               D)
	amortization of costs incurred in connection with any indebtedness secured by any portion of the Property and leasing commissions which have been prepaid;

less:

		
	               E)
	an amount (positive or negative) to offset any rent averaging adjustment resulting from adherence to FASB-13;

		
	               F)
	the amortization of free rent and any other tenant concessions and promotional items not deducted in the calculation of net income above;

		
	               G)
	a replacement reserve for capital improvements, future tenant improvements, leasing commissions and structural items based on not less than  $3.53 per square feet per annum;

		
	               H)
	the amount, if any, by which actual gross income during such fiscal period exceeds that which would be earned from the rental of 87.5% of the gross leasable area in the Property;

		
	               I)
	the amount, if any, by which the actual management fee is less than 3% of the gross revenue during such fiscal period;

		
	               J)
	the amount, if any, by which the actual real estate taxes are less than $3,400,000.00 per annum; and

		
	               K)
	the amount, if any, by which total operating expenses, excluding management fees, real estate taxes and replacement reserves, are less than $8,200,000.00 per annum.

All adjustments to net income referenced above shall be calculated in a manner satisfactory to Mortgagee, in its reasonable discretion.

11

Exhibit-10.76

Financial Statements.  Mortgagor agrees to furnish to Mortgagee:

(A)    the following financial statements for the Property within 90 days after the close of each fiscal year of the Mortgagor (the "Property Financial Statements Due Date"):

		
	(i)
	an unaudited statement of operations for such fiscal year with a detailed line item break-down of all sources of income and expenses, including capital expenses broken down between, leasing commissions, tenant improvements, and capital expenditures; and

		
	(ii)
	a current rent roll identifying location, leased area, lease begin and end dates, current contract rent, rent increases and increase dates, percentage rent, and the expense reimbursements and any other recovery items for each lease; provided, however, that if the expense reimbursements and any other recovery items for each lease are not identified on Mortgagor's form of rent roll, a separate document identifying the expense reimbursements and any other recovery items for each lease if said items shall be required; and

(iii)    an operating budget for the current fiscal year;

(B)    the following financial statements that Mortgagee may, in Mortgagee's sole discretion, require from time to time within 20 days after receipt of a written request from Mortgagee (the "Requested Financial Statements Due Date")

		
	              (i)
	an unaudited balance sheet for Mortgagor as of the last day of Mortgagor's most recently closed fiscal year; and

		
	              (ii)
	an unaudited statement of cash flows for the Mortgagor as of the last day of Mortgagor's most recently closed fiscal year; and 

Furthermore, Mortgagor shall furnish to Mortgagee within 20 days after receipt of a written request from Mortgagee such reasonable financial and management information in the possession of, or accessible to, Mortgagor which Mortgagee determines to be useful in Mortgagee's monitoring of the value and condition of the Property or Mortgagor.

The Property Financial Statements Due Date and the Requested Financial Statements Due Date are each sometimes hereinafter referred to as a "Financial Statements Due Date".

Notwithstanding the foregoing, in no event shall a Financial Statements Due Date for a particular financial statement be prior to the 90th day following the close of the fiscal year covered by such financial statement.

All unaudited statements shall contain a certification by the managing general partner of Mortgagor stating that they have been prepared in accordance with generally accepted accounting principles and that they are true and correct.  The expense of preparing all of the financial statements required in (A) and (B) above, shall be borne by Mortgagor.

Mortgagor acknowledges that Mortgagee requires the financial statements and information required herein to record accurately the value of the Property for financial and regulatory reporting.

In addition to all other remedies available to Mortgagee hereunder, at law and in equity, if any financial statement, additional information or proof of payment of property taxes and assessments is not furnished to Mortgagee as required in this section entitled "Financial Statements" and in the section entitled "Taxes and Special Assessments", within 30 days after Mortgagee shall have given written notice to Mortgagor that it has not been received as required,

(x) interest on the unpaid principal balance of the Indebtedness shall as of the applicable Financial Statements Due Date or the date such additional information or proof of payment of property taxes and assessments was due, accrue and become payable at a rate equal to the sum of the Interest Rate (as defined in the Note) plus one percent (1%) per annum (the "Increased Rate"); and

(y) Mortgagee may elect to obtain an independent appraisal and audit of the Property at Mortgagor's expense, and Mortgagor agrees that it will, upon request, promptly make Mortgagor's books and records regarding the Property available to Mortgagee and the person(s) performing the appraisal and audit (which obligation Mortgagor agrees can be specifically enforced by Mortgagee).

12

Exhibit-10.76

The amount of the payments due under the Note during the time in which the Increased Rate shall be in effect shall be changed to an amount which is sufficient to reflect the Increased Rate with no change in the amortization of the unpaid principal balance.  Interest shall continue to accrue and be due and payable monthly at the Increased Rate until the date (the "Receipt Date") on which all of the financial statements, additional information and proof of payment of property taxes and assessments (as requested by Mortgagee) shall be furnished to or made available to Mortgagee as required.  Commencing on the Receipt Date, interest on the unpaid principal balance of the Note shall again accrue at the Interest Rate with no change in amortization, and the payments due during the remainder of the term of the Note shall be changed to an amount which is sufficient to amortize the then unpaid principal balance at the Interest Rate.  Notwithstanding the foregoing, Mortgagee shall have the right to conduct an independent audit at its own expense at any time.

Future Advances.  This is an Open-End Mortgage securing future advances pursuant to 42 Pa. C.S.A. §8144.  WITHOUT LIMITING ANY OTHER PROVISION OF THIS MORTGAGE, THIS MORTGAGE SECURES UNPAID BALANCES OF ADVANCES MADE, WITH RESPECT TO THE PROPERTY, FOR THE PAYMENT OF TAXES, ASSESSMENTS, MAINTENANCE CHARGES, INSURANCE PREMIUMS OR COSTS INCURRED FOR THE PROTECTION OF THE PROPERTY OR THE LIEN OF THE MORTGAGE, OR EXPENSES INCURRED BY THE MORTGAGEE BY REASON OF A DEFAULT BY THE MORTGAGOR UNDER THIS MORTGAGE.  SUCH ADVANCES INCLUDE, WITHOUT LIMITATION, ALL ADVANCES MADE AS PROVIDED IN THE NOTE AND THE OTHER LOAN DOCUMENTS.  The receipt by Mortgagee of written notice either from Mortgagor or another party, purportedly sent to terminate, limit, or restrict future advances, whether or not such notice is sent pursuant to the provisions of 42 Pa. C.S.A. §8143(b) or 8143(c) and whether or not such notice is effective thereunder, shall be an Event of Default hereunder without the benefit of notice or a cure period for Mortgagor.

Property Management.  The management company for the Property shall be satisfactory to Mortgagee.  Any change in the management company without the prior written consent of Mortgagee shall constitute a default under this instrument.  Notwithstanding the foregoing, TPG, or an Affiliate of TPG, or BDN or an Affiliate of BDN shall be deemed to be a satisfactory management company.

Secondary Financing Permitted.  Upon Mortgagor's written request ("Secondary Financing Request"), which shall specify a dollar amount and other terms desired by Mortgagor, Mortgagee will consider providing additional loan proceeds to be secured by a second lien on the Property (subordinate to Mortgagee's existing lien on the Property).  Notwithstanding the foregoing, if, within 30 days of the Secondary Financing Request, Mortgagee has failed to respond, declined to offer a quote, or offered a quote which Mortgagor has rejected, then Mortgagor shall have the right to obtain third party financing secured only by a lien on the limited partnership interests in Mortgagor but not by a lien on the Property (the "Subordinate Lien") if and only if the following conditions are met:

		
	A.
	no Event of Default has occurred and is continuing under the Loan Documents;

		
	B.
	after full funding of the proposed third party loan ("Third Party Loan") secured by the Subordinate Lien, the loan to value ratio (taking into account all indebtedness secured by the Property and partnership interests in Mortgagor) will not exceed 65%, as determined per Mortgagee's valuation and then-current underwriting; 

		
	C.
	PHILADELPHIA PLAZA - PHASE II, LP (original Mortgagor) shall be the "Borrower" under the Note at the time of funding the Third Party Loan;

		
	D.
	after full funding of the Third Party Loan, the Property will have Debt Service Coverage (calculated per the definition above) of at least 1.25X; 

		
	E.
	The amount of the Third Party Loan shall not exceed $15,000,000.00.  The term of the Third Party Loan shall not be substantially shorter than the term of the loan increase proposed in the Secondary Financing Request referenced above.  If the Third Party Loan amortizes, the amortization term (i.e., whether the amortization is calculated on the basis of 30 years, 25 years, etc.) of the Third Party Loan shall not be substantially shorter than the amortization of the loan increase proposed in the Secondary Financing Request referenced above; 

		
	F.
	The third party lender (the "Third Party Lender") shall enter into an intercreditor agreement with Lender that is consistent with the forms of intercreditor agreements that are customarily entered into by institutional lenders holding senior and mezzanine loans on first class office buildings, whereby the Third Party Lender agrees (i) the Third Party Loan shall be in all respects subject and subordinate to Mortgagee's loan evidenced by the Note ("Mortgagee Loan"), including any amendment, modification, extension or renewal of Mortgagee's Loan, (ii) not to take any affirmative action to hinder or delay an exercise by Mortgagee of its 

13

Exhibit-10.76

rights and remedies including, but not limited to, Mortgagee's right to seek appointment of a receiver for the Property, to notify tenants of the Property to pay rents and other sums due under their leases directly to Mortgagee, and to commence, continue and complete a foreclosure action or other judicial or non-judicial enforcement action, (iii) in the event of a casualty or condemnation, all adjustments of insurance or condemnation  claims or awards shall be handled in accordance with Mortgagee's Loan Documents;

		
	G.
	Mortgagee shall have the right to declare the Note due and payable and to revoke the Mortgagor's license to use and enjoy rents and profits if (i) any default exists under the Loan Documents or under the loan made by the Third Party Lender secured by such other lien beyond any applicable notice and cure period, (ii) such other lien is foreclosed or (iii) such other loan is declared due and payable;

		
	H.
	The Third Party Lender shall be an Institutional Investor, experienced in the placement of commercial mortgage loans; 

		
	I.
	Mortgagee shall receive a true and correct copy of all the Third Party Loan documents and they shall not be materially modified or amended without the prior consent of Mortgagee.  Said prior consent of Mortgagee shall not be unreasonably withheld, conditioned or delayed; and

		
	J.
	Mortgagee shall be paid a fee of $10,000.00 for each such request in consideration of its processing and documentation costs.

"Institutional Investor" shall mean any insurance company, bank, investment bank, savings and loan association, trust company, commercial credit corporation, pension plan, pension fund or pension fund advisory firm, mutual fund or other investment company, government entity or plan, "qualified institutional buyer" within the meaning of Rule 144A under the Securities Act of 1933, as amended (other than a broker/dealer), a real estate investment trust, a private equity fund or an institutional debt fund that invests primarily in real estate or real estate securities and debt, in each case having at least $112,000,000.00 in capital/statutory surplus, shareholder's equity or net worth, as applicable, exclusive of the equity interest in the Property, and being regularly engaged in the business of making or owning commercial real estate loans or interests therein (including loans with respect to commercial real estate) or owning and operating commercial real estate properties.

Any Secondary Financing Request, including any request for third party financing, must be received by Mortgagee on or before the last day of the seventh (7th) year of the term of the Note.

Deposits by Mortgagor.  To assure the timely payment of real estate taxes and special assessments (including personal property taxes, if appropriate), upon the occurrence of an Event of Default, Mortgagee shall thence forth have the option to require Mortgagor to deposit funds with Mortgagee, in monthly or other periodic installments in amounts estimated by Mortgagee from time to time sufficient to pay real estate taxes, special assessments and personal property taxes as they become due.  If at any time the funds so held by Mortgagee shall be insufficient to pay any of said expenses, Mortgagor shall, upon receipt of notice thereof, immediately deposit such additional funds as may be necessary to remove the deficiency.  All funds so deposited shall be irrevocably appropriated to Mortgagee to be applied to the payment of such real estate taxes, special assessments, personal property taxes and, at the option of Mortgagee after the occurrence of an Event of Default, the Indebtedness.

Notices.  Any notices, demands, requests and consents permitted or required hereunder or under any other Loan Document shall be in writing, may be delivered personally or sent by certified mail with postage prepaid or by reputable courier service with charges prepaid.  Any notice or demand sent to Mortgagor by certified mail or reputable courier service shall be addressed to Mortgagor at c/o Thomas Properties Group, Inc., 515 South Flower Street, Sixth Floor, Los Angeles, CA 90071, attention: John R.

14

Exhibit-10.76

Modification of Terms.  Without affecting the liability of Mortgagor or any other person (except any person expressly released in writing) for payment of the Indebtedness or for performance of any obligation contained herein and without affecting the rights of Mortgagee with respect to any security not expressly released in writing, Mortgagee may, at any time and from time to time, either before or after the maturity of the Note, without notice or consent:  (i) release any person liable for payment of all or any part of the Indebtedness or for performance of any obligation; (ii) make any agreement extending the time or otherwise altering the terms of payment of all or any part of the Indebtedness, or modifying or waiving any obligation, or subordinating, modifying or otherwise dealing with the lien or charge hereof; (iii) exercise or refrain from exercising or waive any right Mortgagee may have; (iv) accept additional security of any kind; (v) release or otherwise deal with any property, real or personal, securing the Indebtedness, including all or any part of the Property.

Exercise of Options.  Whenever, by the terms of this instrument, of the Note or any of the other Loan Documents, Mortgagee is given any option, such option may be exercised when the right accrues or at any time thereafter, and no acceptance by Mortgagee of payment of Indebtedness in default shall constitute a waiver of any default then existing and continuing or thereafter occurring.

Nature and Succession of Agreements.  Each of the provisions, covenants and agreements contained herein shall inure to the benefit of, and be binding on, the heirs, executors, administrators, successors, grantees, and assigns of the parties hereto, respectively, and the term "Mortgagee" shall include the owner and holder of the Note.

Legal Enforceability.  No provision of this instrument, the Note or any other Loan Documents shall require the payment of interest or other obligation in excess of the maximum permitted by law.  If any such excess payment is provided for in any Loan Documents or shall be adjudicated to be so provided, the provisions of this paragraph shall govern and Mortgagor shall not be obligated to pay the amount of such interest or other obligation to the extent that it is in excess of the amount permitted by law.

Limitation of Liability.  Notwithstanding any provision contained herein to the contrary, the personal liability of Mortgagor shall be limited as provided in the Note.

Miscellaneous. Time is of the essence in each of the Loan Documents. The remedies of  Mortgagee as provided herein or in any other Loan Document or at law or in equity shall be cumulative and concurrent, and may be pursued singly, successively, or together at the sole discretion of Mortgagee, and may be exercised as often as occasion therefor shall occur; and neither the failure to exercise any such right or remedy nor any acceptance by Mortgagee of payment of Indebtedness in default shall in any event be construed as a waiver or release of any right or remedy.  Neither this instrument nor any other Loan Document may be modified or terminated orally but only by agreement or discharge in writing and signed by Mortgagor and Mortgagee.  If any of the provisions of any Loan Document or the application thereof to any persons or circumstances shall to any extent be invalid or unenforceable, the remainder of such Loan Document and each of the other Loan Documents, and the application of such provision or provisions to persons or circumstances other than those as to whom or which it is held invalid or unenforceable, shall not be affected thereby, and every provision of each of the Loan Documents shall be valid and enforceable to the fullest extent permitted by law.

Defeasance.  Mortgagee agrees that if Mortgagor shall promptly pay or cause to be paid to Mortgagee the Indebtedness, and shall perform or cause to be performed all the other terms, conditions, agreements and provisions contained in the Loan Documents, all without fraud or delay or deduction or abatement of anything or for any reason and Mortgagee shall no longer have any obligation, agreement or commitment to advance any sums to Mortgagor, then this instrument and the estate hereby granted shall cease, terminate and become void.

Waiver of Jury Trial.  To the extent permitted by applicable law, Mortgagor hereby waives any right to trial by jury with respect to any action or proceeding (a) brought by Mortgagor, Mortgagee or any other person relating to (i) the obligations secured hereby and/or any understandings or prior dealings between the parties hereto or (ii) the Loan Documents or the Environmental Indemnity Agreement, or (b) to which Mortgagee is a party.

Captions.  The captions contained herein are for convenience and reference only and in no way define, limit or describe the scope or intent of, or in any way affect this instrument.

Governing Law.  This instrument, the interpretation hereof and the rights, obligations, duties and liabilities hereunder shall be governed and controlled by the laws of the state in which the Property is located.
