 Incentive Stock Option Term Sheet 
 PAETEC CORP. 
 2001 STOCK OPTION AND INCENTIVE PLAN 
 INCENTIVE STOCK OPTION AGREEMENT 
  

	 Incentive Stock Option  
	 This option is intended to be an incentive stock option under Section 422 of the Internal Revenue Code and will be interpreted accordingly.
If you cease to be an employee of the Company, its parent or a subsidiary (“Employee”), but continue to provide Service, this option will be deemed a nonstatutory stock option three months after you cease to be an Employee. In addition, to
the extent that all or part of this option exceeds the $100,000 rule of section 422(d) of the Internal Revenue Code, this option or the lesser excess part will be deemed to be a nonstatutory stock option. 

  

	 Definition of Service  
	 For purpose of this Agreement, “Service” means service as an employee, officer, director or other Service Provider of the Company or an
affiliate of the Company. A change in your position or duties will not result in interrupted or terminated Service, so long as you continue to be an employee, officer, director or other Service Provider of the Company or an affiliate of the Company.
Subject to the preceding sentence, whether a termination of Service will have occurred for purposes of the Plan will be determined by the Board, which determination will be final, binding and conclusive. 

  

	 Vesting  
	 This option is only exercisable before it expires and then only with respect to the vested portion of this option. Subject to the preceding
sentence, you may exercise this option, in whole or in part, to purchase a whole number of vested shares that is equal to or greater than 100 shares, unless the number of shares purchased is the total number available for purchase under this option,
by following the procedures set forth in the Plan and below in this Agreement. 

  

	 	 Your right to purchase shares of Stock under this option vests as to one-fourth (1/4) of the total number of shares covered by this option,
as shown on the cover sheet, on the one-year anniversary of the Vesting Start Date (the “Anniversary Date”), provided you then continue in Service. Thereafter, for each such vesting date that you remain in Service, the number of shares of
Stock which you may purchase under this option will vest at the rate of one-fourth (1/4) per year as of each Anniversary Date. The resulting aggregate number of vested shares will be rounded to the nearest 

  

 2 

	 	 whole number, and you cannot vest in more than the number of shares covered by this option. 

  

	 	 No additional shares of Stock will vest after your Service has terminated for any reason. 

  

	 Exercise Freeze  
	 Notwithstanding any provision of this Agreement to the contrary, this option may not be exercised until the date which is 30 days after the date
on which the Company becomes a reporting company under the Securities Exchange Act of 1934, or any corresponding provision of any successor statute (the “Exchange Act”), with respect to any class of its securities. This prohibition on
exercise is referred to as the “Exercise Freeze.” Notwithstanding the foregoing, the Board may in its discretion at any time prior to such date determine to terminate the Exercise Freeze with respect to all or any portion of this option.

  

	 	 For as long as the Exercise Freeze is in place, if your Service terminates for any reason other than for Cause, you may exercise the portion of
this option that is vested at the time of your termination of Service during the period commencing with the date the Exercise Freeze expires or is terminated and ending on the date that is 30 days following the lifting of such Exercise Freeze, or,
if later, on the date on which the option otherwise may be exercised as described in the applicable section below under “Regular Termination,” “Death,” Disability,” or “Retirement.” In no event may you exercise
this option after the day before the 10th anniversary of the Grant Date, as shown on the cover sheet.

  

	 	 If the Exercise Freeze applicable to this option is not earlier terminated, the Exercise Freeze with respect to this option will automatically
expire on the date that is 31 days before the 10th anniversary of the Grant Date, as shown on the cover sheet. 

  

	 Term  
	 This option will expire in any event at the close of business at Company headquarters on the day before the 10th anniversary of the Grant Date, as
shown on the cover sheet. This option will expire earlier if your Service terminates, as described below. 

  

	 Regular Termination  
	 If your Service terminates for any reason, other than your death, “permanent and total disability” within the meaning of
Section 22(e)(3) of the Code (“Disability”), Retirement (as defined below), or Cause, then this option will expire at the close of business at Company headquarters on the 30th day after your termination date (subject to the special rules regarding the Exercise Freeze described above). 

  

 3 

	 Death  
	 If your Service terminates because of your death, then this option will expire at the close of business at Company headquarters on the date that
is twelve (12) months after the date of death (subject to the special rules regarding the Exercise Freeze described above). During that twelve month period, your estate or heirs may exercise the vested portion of this option.

  

	 	 In addition, if you die during the 30-day period described in connection with a regular termination (i.e., a termination of your Service not on
account of your death, Disability, Cause, or Retirement), and a vested portion of this option has not yet been exercised, then this option will instead expire on the date that is twelve (12) months after your termination date (subject to the
special rules regarding the Exercise Freeze described above). In such a case, during the period following your death up to the date that is twelve (12) months after your termination date, your estate or heirs may exercise the vested portion of
this option. 

  

	 Disability  
	 If your Service terminates because of your Disability, then this option will expire at the close of business at Company headquarters on the date
twelve (12) months after your termination date (subject to the special rules regarding the Exercise Freeze described above). During that twelve month period, you may exercise all or any portion of this option that was vested as of your
termination date. For purposes of this Agreement, Disability means your “permanent and total disability” within the meaning of Section 22(e)(3) of the Code. 

  

	 Termination for Cause  
	 If your Service is terminated for Cause, then you will immediately forfeit all rights to this option and the option will immediately expire. For
purposes of this Agreement, termination for “Cause” will mean termination of your Service with the Company or one of its affiliates due to: (1) failure or refusal to perform the duties assigned to you, including but not limited to
failure to reach assigned goals, quotas and/or objectives, (2) your refusal to follow the reasonable directives of the Board or Chief Executive Officer of the Company or one of its affiliates, or other insubordination, (3) conviction or
plea of guilty or nolo contendere of a felony, or of a misdemeanor involving dishonesty or violence, (4) misappropriation of any funds or property of the Company or any affiliate of the Company, (5) violation of any Company policies,
(6) breach of your confidentiality, non-solicitation and/or non-competition obligations, or (7) commission of any act which could materially injure the business or reputation of, or materially adversely affect the interests of Company or
any affiliate of the Company. 

  

 4 

	 Retirement  
	 If your Service terminates because of your Retirement, then this option will expire at the close of business at Company headquarters on the date
that is three (3) years after the date of Retirement (subject to the special rules regarding the Exercise Freeze described above). During that three year period, you may exercise all or any portion of this option that was vested as of the date
of Retirement. For the purpose of this Agreement, “Retirement” means “Retirement” as defined in the Company’s Retirement Plan as set forth in the Company’s Employee Handbook. 

  

	 Leaves of Absence  
	 For purposes of this option, your Service does not terminate when you go on a bona fide employee leave of absence that was approved by the
Company in writing, if the terms of the leave provide for continued Service crediting, or when continued Service crediting is required by applicable law. However, your Service will be treated as terminating 30 days after you went on employee leave,
unless your right to return to active work is guaranteed by law or by a contract. Your Service terminates in any event when the approved leave ends unless you immediately return to active employee work. 

  

	 	 The Company determines, in its sole discretion, which leaves count , and when your Service terminates, in each case, for all purposes under the
Plan. 

  

	 Notice of Exercise  
	 When you wish to exercise this option, you must notify the Company by filing the proper “Notice of Exercise” form at the address given
on the form. Your notice must specify the number of whole shares you wish to purchase (in a parcel of at least 100 shares, generally). Your notice must also specify how your shares of Stock should be registered (in your name only or in your and your
spouse’s names as joint tenants with right of survivorship, for example). The notice will be effective when it is received by the Company. 

  

	 	 If someone else wants to exercise this option after your death, that person must prove to the Company’s satisfaction that he or she is
entitled to do so. 

  

	 Form of Payment  
	 When you submit your notice of exercise, you must include payment of the option price for the shares you are purchasing. Payment may be made in
one (or a combination) of the following forms: 

  

 5 

	 	 •  Cash, your personal check, a cashier’s check, a money order or another cash equivalent acceptable to the
Company. 

  

	 	 •  To the extent permitted by law and at the discretion of the Board , shares of Stock which have already been
owned by you for more than six months and which are surrendered to the Company. The value of the shares, determined as of the effective date of the option exercise, will be applied to the option price. 

  

	 	 •  To the extent a public market for the Stock exists as determined by the Company, by delivery (on a form
prescribed by the Company) of an irrevocable direction to a licensed securities broker acceptable to the Company to sell Stock and to deliver all or part of the sale proceeds to the Company in payment of the aggregate option price and any
withholding taxes. 

  

	 Withholding Taxes  
	 You will not be allowed to exercise this option unless you make acceptable arrangements to pay any withholding or other taxes that may be due as a
result of the option exercise or sale of Stock acquired under this option. In the event that the Company determines that any federal, state, local or foreign tax or withholding payment is required relating to the exercise or sale of shares arising
from this grant, the Company will have the right to require such payments from you, or withhold such amounts from other payments due to you from the Company or any affiliate of the Company. 

  

	 Transfer of Option  
	 During your lifetime, only you (or, in the event of your legal incapacity or incompetency, your guardian or legal representative) may exercise
this option. You cannot transfer or assign this option. For instance, you may not sell this option or use it as security for a loan. If you attempt to do any of these things, this option will immediately become invalid. You may, however, dispose of
this option in your will or it may be transferred upon your death by the laws of descent and distribution. 

  

	 	 Regardless of any marital property settlement agreement, the Company is not obligated to honor a notice of exercise from your spouse, nor is the
Company obligated to recognize in any manner any purported interest of your spouse in this option. 

  

	 Transfer of Option Shares  
	 Until such time as the Company becomes a reporting company under the Exchange Act with respect to any class of its securities, you may not sell,
assign, pledge, hypothecate, transfer by gift or 

  

 6 

	 	 otherwise dispose of Shares acquired under this option except in transfers back to the Company, transfers by will or the laws of descent and
distribution, or transfers by gift or domestic relations order to “family members” as defined in Rule 701 under the Securities Act of 1933. 

  

	 Retention Rights  
	 Neither this option nor this Agreement give you the right to be retained by the Company (or any affiliate of the Company) in any capacity. The
Company (and any affiliate of the Company) reserves the right to terminate your Service at any time and for any reason. 

  

	 Stockholder Rights  
	 You, or your estate or heirs, have no rights as a stockholder of the Company until you properly exercise this option, in whole or in part, and a
certificate evidencing the shares of Stock subject to such exercise has been issued. No adjustments are made for dividends or other rights if the applicable record date occurs before your stock certificate is issued, except as described in the Plan.

  

	 Adjustments  
	 In the event of a stock split, a stock dividend, reverse stock split or a similar change in the Stock, the number of shares covered by this option
and the option price per share may be adjusted (and rounded down to the nearest whole number) pursuant to the Plan. Your rights with respect to this option will be subject to the terms of the agreement of merger, liquidation or reorganization in the
event the Company is subject to such corporate activity in accordance with the terms of the Plan. 

  

	 Applicable Law  
	 This term sheet and the cover sheet to which it is attached (together with the exhibits and /or schedules attached hereto or thereto), this
“Agreement”) will be interpreted and enforced under the laws of the State of Delaware, other than any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Agreement to the
substantive law of another jurisdiction. 

  

	 Certain Dispositions  
	 If you sell or otherwise dispose of Stock acquired pursuant to the exercise of this option sooner than the one year anniversary of the date you
acquired the Stock, then you agree to notify the Company in writing of the date of sale or disposition, the number of share of Stock sold or disposed of and the sale price per share within 30 days of such sale or disposition.

  

	 Forum Selection  
	 At all times each party hereto (1) irrevocably submits to the exclusive jurisdiction of any New York court or Federal court sitting in New
York; (2) agrees that any action or proceeding arising out of or relating to this Agreement or the transactions 

  

 7 

	 	 contemplated hereby will be heard and determined in such New York or Federal court; (3) to the extent permitted by law irrevocably waives
(i) any objection such party may have to the laying of venue of any such action or proceeding in any of such courts, or (ii) any claim that such party may have that any such action or proceeding has been brought in an inconvenient forum;
and (4) to the extent permitted by law, irrevocably agrees that a final nonappealable judgment in any such action or proceeding will be conclusive and may be enforced in other jurisdictions by suit on the judgment or in any other manner
provided by law. Nothing in this section entitled “Forum Selection” will affect the right of any party hereto to serve legal process in any manner permitted by law.

expenses and other proper charges incurred by the applicable Joint Venture in connection with the operation and maintenance of such Asset during such fiscal period, including, without limitation, management fees, repairs, real estate and chattel
taxes and bad debt expenses, but before payment or provision for debt service charges, income taxes and depreciation, amortization and other non-cash expenses, all as determined in accordance with GAAP, provided that in each case there shall
be no rent leveling adjustments made (and only actual cash rents will be used) when computing Net Operating Income. 
 “Standby Letter of Credit” means any Letter of Credit issued under the Letter of Credit Facility, other than a Trade Letter of Credit or a Bank Guarantee. 
 “Total Asset Value” means, on any date of determination, (a) the sum of the Asset Values for all Assets at
such date, plus (b) all unrestricted cash and Cash Equivalents on hand of the Parent Guarantor and its Subsidiaries. 
 “Total Unencumbered Asset Value” means an amount equal to the sum of the Asset Values of all Unencumbered Assets; provided, however, that, if at any time (a) there shall be fewer than three Unencumbered
Assets, (b) the sum of the Asset Values of all Unencumbered Assets shall not be equal to or greater than $115,000,000 or (c) the weighted average occupancy of all Unencumbered Assets (other than Redevelopment Assets) shall not be greater
than or equal to 85%, the Total Unencumbered Asset Value shall be zero; and provided further that if the sum of the Asset Values of all Unencumbered Assets located in Canada shall exceed 15% of the Total Unencumbered Asset Value, then Total
Unencumbered Asset Value shall be reduced by the amount of such excess (“Excess Canada Value”) other than for purposes of calculating compliance with the financial covenant set forth in Section 5.04(b)(i), with respect
to which such reduction shall not apply; and provided still further that if the sum of the Asset Values of all Unencumbered Assets comprised of Redevelopment Assets shall exceed 25% of the Total Unencumbered Asset Value, then Total
Unencumbered Asset Value shall be reduced by the amount of such excess (“Excess Redevelopment Value”). 
 “Unencumbered Asset Conditions” means, with respect to any Proposed Unencumbered Asset, that such Proposed Unencumbered Asset (a) is an Office Asset or Redevelopment Asset located in the United States of America
or Canada, (b) is owned in fee simple absolute or subject to a Qualifying Ground Lease, (c) [intentionally omitted], (d) except in the case of a Redevelopment Asset, is income-producing, (e) is free of all structural

 5 

 
conditions or other matters (including a casualty event or condemnation) that would have a material adverse affect on the value, use or ability to sell or
refinance such Asset, (f) except in the case of any non-income producing Redevelopment Asset, is operated by a property manager reasonably acceptable to the Administrative Agent, (g) is not subject to mezzanine Debt financing, (h) is
not subject to any Lien (other than Permitted Liens) or any Negative Pledge, (i) to the extent owned by a Loan Party that is a Subsidiary of the Borrower, none of the Borrower’s direct or indirect Equity Interests in such Subsidiary owner
is subject to any Lien (other than Permitted Liens) or any Negative Pledge, (j) is an Asset with respect to which the Borrower directly, or indirectly through such Subsidiary owner, has the right to take the following actions without the need
to obtain the consent of any Person: (i) to create Liens on such Asset as security for the Obligations of the Loan Parties under or in respect of the Loan Documents, and (ii) to sell, transfer or otherwise dispose of such Asset,
(k) is owned directly by the Borrower or a Guarantor, and (l) in the case of any Redevelopment Asset, such Asset has a minimum Estimated NOI Yield of not less than 10%. 
 “Unencumbered Assets” means only those Office Assets and Redevelopment Assets (a) for which the applicable
conditions (as may be determined by the Administrative Agent in its sole discretion) in Section 3.01 and, if applicable, 5.01(j)(iii) have been satisfied and as the Administrative Agent or the Required Lenders, in their sole discretion, shall
from time to time elect to consider Unencumbered Assets for purposes of this Agreement, and (b) listed on Schedule II hereto (as supplemented from time to time pursuant to Section 5.01(j)(iii)). Without limitation of the foregoing, no
Redevelopment Asset shall qualify as an Unencumbered Asset without the prior approval of the Administrative Agent (which approval shall not be unreasonably withheld). 
 “Unsecured Debt” means, at any date of determination, the amount at such time of all Consolidated Debt of the
Parent Guarantor and its Subsidiaries, including, without limitation, the Facility Exposure (as defined herein), but exclusive of (a) Debt secured by any Lien, (b) guarantee obligations in respect of Debt secured by any Lien, and
(c) guaranties by parent entities of the Recourse Debt of one or more of their respective Subsidiaries in an aggregate amount not greater than 5.0% of Total Asset Value. 
 (c) The definition of “Non-Recourse Debt” set forth in Section 1.01 of the Credit Agreement is hereby amended by adding the
following to the end thereof: “Any Debt for Borrowed Money that would otherwise qualify as Non-Recourse Debt under this definition shall not fail to qualify as Non-Recourse Debt solely by reason of any recourse guaranty of such Debt by the
Parent Guarantor or any of its Subsidiaries, so long as such recourse guaranty is permitted pursuant to Section 5.02(b)(iii)(C) (including the proviso therein).” 
 (d) Section 2.01(b) of the Credit Agreement is hereby amended and restated in its entirety to read as follows: 
 “(b) Letters of Credit. Each U.S. Dollar Issuing Bank severally agrees, on the terms and conditions hereinafter set
forth, to issue (or cause its Affiliate that is a commercial bank to issue on its behalf) letters of credit denominated in Dollars (the “U.S. Dollar Letters of Credit”), for the account of the Borrower from time to time on
any Business Day during the period from the date hereof until 60 days before the Termination Date in an aggregate Available Amount (i) for all U.S. Dollar Letters of Credit not to exceed at any time the U.S. Dollar Letter of Credit
Facility at such time, (ii) for all U.S. Dollar Letters of Credit issued by such Issuing Bank not to exceed such Issuing Bank’s U.S. Dollar Letter of Credit Commitment at such time, and (iii) for each such U.S. Dollar

  

 6 

 
Letter of Credit not to exceed the Unused U.S. Dollar Revolving Credit Commitments of the Lenders at such time. Each Multicurrency Issuing Bank
severally agrees, on the terms and conditions hereinafter set forth, to issue (or cause its Affiliate that is a commercial bank to issue on its behalf) letters of credit denominated in Dollars or in a Committed Foreign Currency and Bank Guarantees
denominated in Euros or Sterling (such letters of credit and Bank Guarantees, collectively, the “Multicurrency Letters of Credit”), for the account of the Borrower from time to time on any Business Day during the period from
the date hereof until 60 days before the Termination Date in an aggregate Available Amount (X) for all Multicurrency Letters of Credit not to exceed at any time the Multicurrency Letter of Credit Facility at such time, (Y) for all
Multicurrency Letters of Credit issued by such Issuing Bank not to exceed such Issuing Bank’s Multicurrency Letter of Credit Commitment at such time, and (Z) for each such Multicurrency Letter of Credit not to exceed the Unused
Multicurrency Revolving Credit Commitments of the Lenders at such time. No Letter of Credit shall have an expiration date (including all rights of the Borrower or the beneficiary to require renewal) later than (A) in the case of a Standby
Letter of Credit, the earlier of (1) 60 days before the Termination Date and (2) one year after the date of issuance thereof, but may by its terms be renewable annually upon notice (a “Notice of Renewal”) given to
the Issuing Bank that issued such Standby Letter of Credit and the Administrative Agent on or prior to any date for notice of renewal set forth in such Letter of Credit but in any event at least three Business Days prior to the date of the proposed
renewal of such Standby Letter of Credit and upon fulfillment of the applicable conditions set forth in Article III unless such Issuing Bank has notified the Borrower (with a copy to the Administrative Agent) on or prior to the date for notice
of termination set forth in such Letter of Credit but in any event at least 30 Business Days prior to the date of automatic renewal of its election not to renew such Standby Letter of Credit (a “Notice of Termination”),
(B) in the case of a Trade Letter of Credit, the earlier of (1) 60 days before the Termination Date, and (2) 60 days after the date of issuance thereof, and (C) in the case of a Bank Guarantee, 60 days before the Termination
Date; provided, however, that the terms of each Standby Letter of Credit that is automatically renewable annually shall (x) require the Issuing Bank that issued such Standby Letter of Credit to give the beneficiary named in such
Standby Letter of Credit notice of any Notice of Termination, (y) permit such beneficiary, upon receipt of such notice, to draw under such Standby Letter of Credit prior to the date such Standby Letter of Credit otherwise would have been
automatically renewed and (z) not permit the expiration date (after giving effect to any renewal) of such Standby Letter of Credit in any event to be extended to a date later than 60 days before the Termination Date. If either a Notice of
Renewal is not given by the Borrower or a Notice of Termination is given by the relevant Issuing Bank pursuant to the immediately preceding sentence, such Standby Letter of Credit shall expire on the date on which it otherwise would have been
automatically renewed; provided, however, that even in the absence of receipt of a Notice of Renewal the relevant Issuing Bank may in its discretion, unless instructed to the contrary by the Administrative Agent or the Borrower, deem that a
Notice of Renewal had been timely delivered and in such case, a Notice of Renewal shall be deemed to have been so delivered for all purposes under this Agreement. Each Standby Letter of Credit and Bank Guarantee shall contain a provision authorizing
the Issuing Bank that issued such Letter of Credit to deliver to the beneficiary of such Letter of Credit, upon the occurrence and during the continuance of an Event of Default, a notice (a “Default Termination Notice”)
terminating such Letter of Credit and giving such beneficiary 15 days to draw such Letter of Credit. Within the limits of the Letter of Credit Facility, and subject to the limits referred to above, the Borrower may request the issuance of Letters of
Credit under this Section 2.01(b), repay any Letter of Credit Advances resulting from 

  

 7 

 
drawings thereunder pursuant to Section 2.03(c) and request the issuance of additional Letters of Credit under this Section 2.01(b).”

 (e) The second sentence of Section 2.03(a) of the Credit Agreement is hereby amended and restated in its entirety to
read as follows: 
 “Each such notice of issuance of a Letter of Credit (a “Notice of Issuance”) shall be by
telephone, confirmed immediately in writing, telex, telecopier or e-mail, in each case specifying therein the requested (i) date of such issuance (which shall be a Business Day), (ii) currency of such Letter of Credit and the Letter of
Credit Facility pursuant to which such Letter of Credit shall be issued, (iii) Available Amount of such Letter of Credit, (iv) expiration date of such Letter of Credit, (v) name and address of the beneficiary of such Letter of Credit
and (vi) form of such Letter of Credit, and shall be accompanied by such application and agreement for letter of credit as such Issuing Bank may specify to the Borrower for use in connection with such requested Letter of Credit (a
“Letter of Credit Agreement”).” 
 (f) Section 2.03(c) of the Credit Agreement is hereby
amended and restated in its entirety to read as follows: 
 “(c) Drawing and Reimbursement. The payment by any
Issuing Bank of a draft drawn under any Letter of Credit shall constitute for all purposes of this Agreement the making by such Issuing Bank of a Letter of Credit Advance, which shall be a Base Rate Advance, in the amount of such draft. Upon written
demand by any Issuing Bank with an outstanding Letter of Credit Advance, with a copy of such demand to the Administrative Agent, each U.S. Dollar Revolving Lender (in the case of an Advance pursuant to a U.S. Dollar Letter of Credit only)
and each Multicurrency Revolving Lender (in the case of an Advance pursuant to a Multicurrency Letter of Credit only) (in each case, an “Applicable Lender”) shall purchase from such Issuing Bank, and such Issuing Bank shall
sell and assign to each such Applicable Lender, such Lender’s Applicable Pro Rata Share of such outstanding Letter of Credit Advance as of the date of such purchase, by making available for the account of its Applicable Lending Office to the
Administrative Agent for the account of such Issuing Bank, by deposit to the Administrative Agent’s Account, in same day funds, an amount equal to the portion of the outstanding principal amount of such Letter of Credit Advance to be purchased
by such Applicable Lender. Promptly after receipt thereof, the Administrative Agent shall transfer such funds to such Issuing Bank. The Borrower hereby agrees to each such sale and assignment. Each Applicable Lender agrees to purchase its Applicable
Pro Rata Share of an outstanding Letter of Credit Advance on (i) the Business Day on which demand therefor is made by the Issuing Bank which made such Advance, provided that notice of such demand is given not later than 11:00 A.M.
(New York City time) on such Business Day, or (ii) the first Business Day next succeeding such demand if notice of such demand is given after such time. Upon any such assignment by an Issuing Bank to any Applicable Lender of a portion of a
Letter of Credit Advance, such Issuing Bank represents and warrants to such Applicable Lender that such Issuing Bank is the legal and beneficial owner of such interest being assigned by it, free and clear of any liens, but makes no other
representation or warranty and assumes no responsibility with respect to such Letter of Credit Advance, the Loan Documents or any Loan Party. If and to the extent that any Applicable Lender shall not have so made the amount of such Letter of Credit
Advance available to the Administrative Agent, such Applicable Lender agrees to pay to the Administrative Agent forthwith on demand such amount together with interest thereon, for each day from the date of demand by such Issuing Bank until the date
such amount is paid to the 

  

 8 

 
Administrative Agent, at the Federal Funds Rate for its account or the account of such Issuing Bank, as applicable. If such Applicable Lender shall pay to
the Administrative Agent such amount for the account of such Issuing Bank on any Business Day, such amount so paid in respect of principal shall constitute a Letter of Credit Advance made by such Applicable Lender on such Business Day for purposes
of this Agreement, and the outstanding principal amount of the Letter of Credit Advance made by such Issuing Bank shall be reduced by such amount on such Business Day.” 
 (g) Section 2.05(b)(i) of the Credit Agreement is hereby amended and restated in its entirety to read as follows: 
 “(i) The U.S. Dollar Letter of Credit Facility shall be permanently reduced from time to time on the date of each reduction in
the U.S. Dollar Revolving Credit Facility by the amount, if any, by which the amount of the U.S. Dollar Letter of Credit Facility exceeds the U.S. Dollar Revolving Credit Facility after giving effect to such reduction of the
U.S. Dollar Revolving Credit Facility. The Multicurrency Letter of Credit Facility shall be permanently reduced from time to time on the date of each reduction in the Multicurrency Revolving Credit Facility by the amount, if any, by which the
amount of the Multicurrency Letter of Credit Facility exceeds the Multicurrency Revolving Credit Facility after giving effect to such reduction of the Multicurrency Revolving Credit Facility.” 
 (h) Section 2.06(b)(iii) of the Credit Agreement is hereby amended and restated in its entirety to read as follows: 
 “(iii) In the event the aggregate Available Amount under all outstanding U.S. Dollar Letters of Credit shall exceed the
aggregate U.S. Dollar Letter of Credit Commitments of the Lenders, the Borrower shall, within five Business Days after written demand by the Administrative Agent, pay to the Administrative Agent for deposit in the L/C Cash Collateral Account an
amount sufficient to cause the aggregate amount on deposit in the L/C Cash Collateral Account in respect of U.S. Dollar Letters of Credit (e.g., without reference to any amounts on deposit therein in respect of Multicurrency Letters of
Credit) to equal the amount by which the aggregate Available Amount of all U.S. Dollar Letters of Credit then outstanding exceeds the U.S. Dollar Letter of Credit Facility on such Business Day, provided that such deposit shall only be
required to be maintained therein for so long as such aggregate Available Amount exceeds the U.S. Dollar Letter of Credit Facility. In the event the aggregate Available Amount under all outstanding Multicurrency Letters of Credit shall exceed
the aggregate Multicurrency Letter of Credit Commitments of the Lenders, the Borrower shall, within five Business Days after written demand by the Administrative Agent, pay to the Administrative Agent for deposit in the L/C Cash Collateral Account
an amount in Dollars sufficient to cause the aggregate amount on deposit in the L/C Cash Collateral Account in respect of Multicurrency Letters of Credit (e.g., without reference to any amounts on deposit therein in respect of
U.S. Dollar Letters of Credit) to equal the amount by which the aggregate Available Amount of all Multicurrency Letters of Credit then outstanding exceeds the Multicurrency Letter of Credit Facility on such Business Day, provided that such
deposit shall only be required to be maintained therein for so long as such aggregate Available Amount exceeds the Multicurrency Letter of Credit Facility.” 
 (i) Section 2.18(a) of the Credit Agreement is hereby amended by deleting the reference to “$500,000,000” set forth therein
and substituting “$750,000,000” therefor. 
  

 9 

 (j) Section 4.01(b) of the Credit Agreement is hereby amended by adding at the end
thereof prior to the period: “(other than Liens on Equity Interests in Property-Level Subsidiaries securing Non-Recourse Debt permitted under Section 5.02(b)(ii)(G))”. 
 (k) Clause (A) of Section 5.01(j)(iii) of the Credit Agreement is hereby amended by (i) deleting the word “and”
at the end of subparagraph (4) thereof, (ii) deleting the semi-colon at the end of subparagraph (5) thereof and substituting “, and” therefor, and (iii) adding thereto the following new subparagraph (6) immediately
prior to the proviso following subparagraph (5) thereof: 
 “(6) in the case of any Proposed Unencumbered Asset that
is a Redevelopment Asset, a certificate of the Chief Financial Officer (or other Responsible Officer) of the Borrowing stating that (x) the Estimated NOI Yield for such Asset satisfies the requirements of clause (l) of the definition of
“Unencumbered Asset Conditions”, and (y) set forth on schedules attached to such certificate are a capital expenditures budget and projected operating statements for such Redevelopment Asset;” 
 (l) Clause (iv) of the proviso following clause (A) of Section 5.01(j)(iii) is hereby amended and restated in its entirety
to read as follows: 
 “(iv) (x) the Fusepoint Asset shall be deemed to satisfy clause (k) of the definition of
“Unencumbered Asset Conditions” so long as the Fusepoint Owner shall at all times (1) be a direct Subsidiary of the Borrower or a Guarantor and (2) hold title to the Fusepoint Asset for the sole use, benefit and advantage of the
Borrower or a Guarantor, all as set forth in the Fusepoint Owner’s Declaration of Trust, and (y) if the Fusepoint Owner shall at any time fail to satisfy the requirements of the foregoing clause (x), then the Fusepoint Asset shall be
excluded as an Unencumbered Asset,” 
 (m) Clause (C) of Section 5.02(b)(iii) of the Credit Agreement is hereby
amended and restated in its entirety to read as follows: 
 “(C) Recourse Debt (whether secured or unsecured) in an
amount not to exceed in the aggregate 40% of Total Asset Value; provided, however, that any recourse guaranties of Non-Recourse Debt (exclusive of Customary Carve-Out Agreements) otherwise permitted under this clause (C) shall not
exceed in the aggregate 5% of Total Asset Value;” 
 (n) Clause (A) of Section 5.02(f)(iv) of the Credit
Agreement is hereby amended and restated in its entirety to read as follows: 
 “(A) Investments in land, Redevelopment
Assets and Development Assets (including such assets that such Person has contracted to purchase for development with or without options to terminate the purchase agreement), so long as (1) the aggregate amount of all such Investments,
calculated on the basis of actual cost, does not at any time exceed 15.0% of Total Asset Value at such time, and (2) the aggregate amount of all Investments referred to in clause (1) above comprised of Investments in undeveloped land does
not at any time exceed 5.0% of Total Asset Value at such time; provided, however, that the limitations set forth in this clause (A) shall not apply to any Redevelopment Asset or Development Asset that is 85% pre-leased pursuant to duly
executed Tenancy Leases and all completion and performance guarantees pertaining to such Asset are reasonably satisfactory to the Administrative Agent, and” 
  

 10 

 (o) Section 5.04(a)(iii) of the Credit Agreement is hereby amended by deleting the

 CONSENT 
 Dated as of December 15, 2006
