 4. Additional Tenant Improvement Allowance. Landlord
acknowledges and agrees that, subject to the provisions of Paragraph 18 hereof, upon the execution and delivery of this Amendment by the parties hereto, Landlord shall pay to Tenant, in cash, One Million Dollars ($1,000,000.00). Such amount is in
addition to, and not in substitution or in lieu of, any other allowance provided or available to Tenant under the Master Lease, including without limitation, under Article 6 and Exhibit I of the Master Lease. Tenant’s right to receive such
payment shall 
  

 6 








 accrue immediately upon the mutual execution and delivery of this Amendment, subject to the provisions of Paragraph 18
hereof, and there shall be no other conditions to Tenant’s right to receive such payment. In furtherance of the foregoing, Tenant shall not be required to submit or provide any receipts or other evidence regarding the costs of any improvements
undertaken by Tenant in the Premises, and there shall be no restrictions as to the use made by Tenant of such payment. 
  
 5. Extension of Initial Term; Amendment Regarding Renewal Terms. The parties hereto acknowledge and agree that the expiration date of the
Initial Term is currently December 31, 2007. By this Amendment, the Initial Term of the Master Lease with respect to all floors of the Premises (except the Twelfth Floor) is hereby extended from January 1, 2008 through December 31, 2014. The Initial
Term of the Master Lease with respect to the Twelfth Floor shall end on December 31, 2007, subject to Tenant’s right to renew the term with respect to Twelfth Floor set forth in Paragraph 8 hereof. The parties further acknowledge and agree that
the provisions of Section 2.3 of the Master Lease are hereby amended to provide that the Renewal Options (except with respect to the Twelfth Floor) shall consist of Tenant’s right to renew this Lease for two (2) successive terms of five (5)
years each, and such terms shall be the Renewal Terms. The reference in Section 2.3 of the Master Lease to “one final term of four (4) years” is hereby deleted. 
  
 6. Renewal Term Basic Rent. The first sentence of Section 3.1(b) of the Master Lease is hereby deleted and
replaced with the following sentence: “For each Renewal Term, Basic Rent shall be adjusted to an amount (“Renewal Term Rent”) which shall be equal to ninety five percent (95%) of fair market rent (“Value”) for
such Renewal Term.” 
  

 7 








 7. Operating Rent. 
  
 (a) Premises (other than the Twelfth Floor). For purposes of calculating Tenant’s Operating Rent for
the balance of the Initial Term as extended hereunder (except with respect to the Twelfth Floor): 
  
 (i) the Base Year shall be calendar year 2004. The Base Year for the first Renewal Term shall be calendar year 2015 and the Base Year for
the second Renewal Term shall be calendar year 2020. 
  
 (ii) Tenant’s Share shall be deemed to be 53.94%, with respect to the Premises other than the Twelfth Floor, subject to adjustment from time to time based on changes in the size of the Premises pursuant to the Master Lease and any
subsequent amendments to the Master Lease; 
  
 (iii) Annual increases in Tenant’s Share of Controllable Operating Expenses (as hereinafter defined) shall not exceed four percent (4%) of the corresponding charge for the immediately preceding calendar year. “Controllable
Operating Expenses” shall mean all Operating Expenses other than Non-Controllable Operating Expenses. “Non-Controllable Operating Expenses” shall mean Taxes, Utility Charges, Insurance Premiums and costs and expenses paid
by Landlord pursuant to prevailing union wage rates and benefits included in amounts paid by Landlord for Building janitorial services; 
  
 (iv) There shall be no limitation on increases in Tenant’s Share of Non-Controllable Operating Expenses and there shall be no
automatic or minimum increases in Non-Controllable Operating Expenses; and 
  
 (v) Notwithstanding anything in the Master Lease or this Sixth Amendment to the contrary, Landlord acknowledges and agrees that any reduction in any category of Non-Controllable Operating Expenses (including, without
limitation, reductions 
  

 8 








 resulting in any category of Non-Controllable Expenses in any Lease Year being less than such category of
Non-Controllable Expenses in the Base Year) shall be applied to reduce any increases in other Operating Expenses (but shall not be applied to reduce Base Rent) during that Lease Year or subsequent Lease Years. 
  
 (b) Twelfth Floor. Landlord and Tenant acknowledge
and agree that Tenant’s obligations with respect to Operating Rent payable with respect to the Twelfth Floor are not changed or modified in any respect by this Sixth Amendment during the balance of the term of the Master Lease relating to the
Twelfth Floor, which expires on December 31, 2007. In furtherance of, but not in limitation of, the foregoing, the Base Year with respect to the Twelfth Floor shall remain calendar year 1993 for the balance of such term, and Tenant’s Share for
purposes of determining Tenant’s Operating Rent obligations with respect to the Twelfth Floor shall be 3.99%. If Tenant exercises its right set forth in Paragraph 8 of this Sixth Amendment to extend the term of the Master Lease with respect to
the Twelfth Floor, then the Base Year with respect to the Twelfth Floor during such extended term or terms shall be 2004 and the foregoing provisions of this Paragraph 7 preceding this grammatical paragraph shall apply to the Twelfth Floor during
such extended term or terms. 
  
 (c) Base
Years. Landlord covenants and agrees that with respect to each Base Year hereunder, it shall operate the Building in accordance with its customary practice and shall not accelerate the payment of any Taxes, Utility Charges, Insurance Premiums or
other components of Operating Rent into the calendar year prior to the Base Year or defer any of such charges to years subsequent to the Base Year for the purpose of reducing the Taxes, Utility Charges, Insurance Premiums and other components of
Operating Rent during the Base Year. Landlord further acknowledges that the “gross-up” provision set forth in the final sentence of 
  

 9 








 paragraph (i) in the definition of “Operating Expenses” in Section 1.1 (nn) of the Master Lease
shall apply to the determination of Operating Expenses in any Base Year. 
  
 8. Reed Smith LLP. Landlord acknowledges that if Tenant’s subtenant Reed Smith elects to relocate to the eleventh (11th) floor of the Building as either a subtenant of Tenant or a direct tenant of
Landlord, Landlord will cooperate with Tenant and Reed Smith to effect such relocation. Alternatively, if Reed Smith desires to enter into a direct lease with Landlord for the Twelfth Floor, Landlord will cooperate with Tenant and Reed Smith
regarding such direct lease. Upon either occurrence, Landlord and Tenant shall enter into a further amendment to the Lease reflecting Tenant’s resulting surrender of the Twelfth Floor. Landlord shall have the right, but not the obligation, to
enter into direct lease negotiations with Reed Smith for the eleventh [11th] or Twelfth Floor space upon
commercially reasonable terms and conditions. If, despite such negotiations, Landlord and Reed Smith cannot consummate a lease for either floor to extend its tenancy beyond the December 31, 2007 expiration date of its sublease with Tenant, then
Tenant shall have the right, but not the obligation, to extend the term of the Master Lease with respect to the Twelfth Floor for a period of not less than three (3) years, nor more than seven (7) years at a Base Rent equal to Twenty-Two and 75/100
Dollars ($22.75) per Square Foot per year. To exercise such right to extend the term with respect to the Twelfth Floor, Tenant shall deliver written notice to Landlord no later than June 30, 2007 specifying the duration of the extended term as
provided above. If Tenant elects to extend the term with respect to the Twelfth Floor for five (5) years (until December 31, 2012) then Tenant shall have the right, by written notice to Landlord no later than June 30, 2012, to further extend the
term with respect to the Twelfth Floor until December 31, 2014. In addition, if Tenant elects to extend the term of the Master Lease with respect to the Twelfth Floor until December 31, 2014, Tenant shall have the right to include 
  

 10 








 or not include the Twelfth Floor in any exercise by Tenant of its Renewal Options hereunder, subject to the terms and
conditions of the Master Lease. 
  
 9. Right to Reduce Size
of Premises. As of the Effective Date, all references in the Master Lease, as amended, to Tenant’s right to reduce the size of the Premises, including but not limited to Section 2.5 thereof, shall be deemed deleted in their entirety and
shall be replaced by the following: 
  
 (a) By no
later than November 30, 2004, Tenant may elect to provide Landlord with written notice of its intention to reduce the size of the Premises by surrendering either or both of the following: (i) no less than one-half (1/2) of the tenth (10th) floor (containing 21,352 Square Feet), and/or (ii) the portion of the eighth (8th) floor of the Building which is part of the Premises (11,279 Square Feet), in each case effective 365 days from the date such written notice is received by
Landlord (“First Surrender Date”) (said space being sometimes hereinafter referred to as “Reduction Space” or “Reduction Spaces”). If such notice should be given in a timely manner, Tenant shall
vacate and surrender possession of whichever Reduction Space Tenant has elected to surrender in broom-clean condition by no later than the First Surrender Date and the Master Lease will be amended to reflect the surrender of such Reduction Space as
of the First Surrender Date. If such written notice is not served in a timely manner as required above, Tenant’s right to surrender such Reduction Space as of such date shall lapse and become null and void and of no further force and effect.

  
 (b) If any Reduction Space remains to be
surrendered following the First Surrender Date, by no later than December 31, 2006, Tenant may elect to provide Landlord with written notice of its intention to reduce the size of the Premises by surrendering whichever Reduction Space remains to be
surrendered effective 365 days from the date such written notice 
  

 11 








 is received by Landlord (“Second Surrender Date”). If such notice should be given in a
timely manner, Tenant shall vacate and surrender possession of such Reduction Space in broom-clean condition by no later than the Second Surrender Date and the Master Lease will be amended to reflect the surrender of such Reduction Space as of the
Second Surrender Date. If such written notice is not served in a timely manner as required above, Tenant’s right to surrender whatever Reduction Space which has not been surrendered shall lapse and become null and void and of no further force
and effect. 
  
 (c) Any Refurbishment Allowance
otherwise due and owing with respect to these Reduction Spaces shall be deferred as provided in this paragraph (c). Tenant shall forfeit any Refurbishment Allowance otherwise due and owing with respect to any Reduction Space which Tenant has
surrendered to Landlord effective as of the date on which Tenant delivers such Reduction Space to Landlord. With respect to all Reduction Space that is not surrendered by Tenant pursuant to this Section 9, Landlord shall pay to Tenant, on January 1,
2007, any and all Refurbishment Allowances otherwise due and owing with respect to such space. 
  

 12 








 10. Tenant’s Right to Terminate. 
  
 (a) Landlord and Tenant mutually acknowledge and agree that
the City of Pittsburgh, Allegheny County and/or the Commonwealth of Pennsylvania (individually, a “Government Authority” and collectively, “Governmental Authorities”) are facing current revenue shortfalls and that,
accordingly, any or all of these Governmental Authorities may, at some time during the balance of the term of the Master Lease, impose additional taxes (excluding ad valorem real property taxes), materially increase existing tax rates (excluding ad
valorem real property taxes), expand the scope or applicability of existing taxes (excluding ad valorem real property taxes) or eliminate or reduce existing tax exemptions, exclusions or abatements (excluding ad valorem real property taxes)
(“Future Adverse Tax Changes”). In the event that Future Adverse Tax Changes are imposed or enacted by any one or more of the Governmental Authorities after the Effective Date and, as a direct and proximate consequence thereof: (i)
Tenant can demonstrate to Landlord, by the production of commercially reasonable documentary evidence prepared by an independent public accounting firm, that such Future Adverse Tax Changes have caused Tenant’s business operations in the
Premises to incur an additional tax liability of at least Five Million Dollars ($5,000,000.00) during any calendar year; and (ii) Tenant elects to relocate its business from the Premises to a location outside of the jurisdiction of the Governmental
Authority responsible for imposing or enacting the Future Adverse Change, then, in such an event, Tenant may elect to terminate the Master Lease upon one hundred eighty (180) days’ prior written notice to Landlord. 
  
 (b) If the foregoing termination right should arise and
Tenant should exercise such right, Landlord shall be entitled to recoup from Tenant the sum more particularly detailed in Exhibit “A” attached hereto and made a part hereof (based on the dollar amounts and line items 
  

 13 








 set forth in Exhibit A and the amortization set forth in the schedules prepared by Landlord attached to
Exhibit A) and which is further described as the unearned portion of that benefit which will have accrued to Tenant by virtue of this Amendment based on the date upon which such termination shall have occurred. Such payment shall be made by Tenant
to Landlord no later than the expiration date of the Term as determined by the exercise of the foregoing termination right. 
  
 11. After-Hours HVAC Service. As of the Effective Date, Tenant shall have the right, from time to time, but no more frequently than once per
calendar year, to elect by written notice to Landlord to pay, in lieu of hourly charges for After-Hours HVAC service on Mondays through Saturdays on the twenty-fifth (25th) and/or twenty-sixth (26th) floors, a flat annual charge of Eighteen Thousand Five Hundred Sixty and 00/100 Dollars ($18,560.00) per floor. If Tenant elects to exercise such right, then HVAC operation on the floor or floors selected by Tenant shall be
extended to twenty-four (24) hours per day from 7:00 A.M. to 7:00 A.M. Tenant shall have the right thereafter, from time to time, to change its election from hourly to the foregoing flat charge and vice versa based on its use of one or both of such
floors. 
  
 12. Building Security. Landlord and
Tenant agree to meet on an as-needed basis to discuss Tenant’s Building Security concerns and use mutual good faith and diligent efforts to develop a workable plan to respond to Tenant’s Building Security concerns. 
  
 13. Applicable Law. The laws of the Commonwealth of
Pennsylvania shall govern the validity, performance and enforcement of this Amendment. The invalidity or unenforceability of any provision of this Amendment shall not affect or impair any other provision. 
  

 14 








 14. Interpretation. In the event of any conflict between the provisions of the Master Lease
and the provisions of this Amendment, the provisions of this Amendment shall control. 
  
 15. Execution. This Amendment may be signed in counterparts, each of which shall be deemed an original, but all of which shall be deemed but one and the same instrument. 
  
 16. Full Force and Effect. Except as specifically set forth
herein, the terms, covenants and conditions of the Master Lease shall remain in full force and effect. Neither the Master Lease, as amended, nor this Sixth Amendment may be further modified or amended, except in writing signed by both Landlord and
Tenant. This Sixth Amendment sets forth the entire understanding of the parties hereto with respect to the matters set forth herein. Landlord and Tenant each hereby ratify and reaffirm all of the remaining terms and conditions of the Master Lease,
as amended. Landlord acknowledges that notwithstanding the reduction in the size of the Premises contemplated by this Sixth Amendment and notwithstanding the provisions of Section 8 of the Fourth Amendment to the Master Lease, Tenant shall not be
required to pay any rent for the sign space on the roof of the Building occupied by Tenant pursuant to the Fourth Amendment to the Master Lease. However, in the event that at any time during the balance of the Initial Term or any Renewal Term,
Tenant shall occupy less than 100,000 Square Feet in the Building, Tenant’s sign rights as set forth in the Fourth Amendment shall be deemed null and void and of no further force and effect. Tenant hereby acknowledges that, to the best of
Tenant’s knowledge as of the date of this Sixth Amendment, Landlord is not in default under the terms and conditions of the Master Lease, as amended. Landlord hereby acknowledges that, to the best of Landlord’s knowledge as of the date of
this Sixth Amendment, Tenant is not in default under the terms and conditions of the Master Lease, as amended. 
  

 15 








 17. Confidentiality of Terms. Landlord and Tenant covenant and agree to maintain the terms
of this Amendment and all documents produced in connection therewith as strictly confidential. In no event shall Landlord or Tenant disclose or publish any such information to any third persons or parties except: (i) either party may disclose the
terms of this Amendment to its lenders, accountants, attorneys, employees or tax advisors to whom disclosure is necessary, provided that such individuals are advised of the confidentiality provisions hereof; or (ii) as may be agreed upon in writing
by the other party. Notwithstanding the foregoing, Landlord, with Tenant’s prior written consent as to both form and content, may generate an announcement regarding Tenant’s extension of the Master Lease without divulging any specifics of
the Amendment. 
  
 18. Lender Consent. This
Amendment and the rights and obligations of the parties hereunder shall not become effective until Tenant and Landlord shall have received the written consent of Teachers Insurance Annuity Association of America, 730 Third Avenue, New York, New York
10017, Attention: Senior Vice President – Mortgage and Real Estate, to this Amendment, and Landlord agrees to use commercially reasonable efforts to obtain such consent as soon as possible following the mutual execution and delivery of this
Amendment. 
  
 19. Brokers. Landlord hereby warrants
to Tenant that no real estate broker other than Grant Street Associates has or will represent Landlord in this transaction. Tenant hereby warrants to Landlord that no real estate broker has or will represent Tenant in this transaction. Landlord and
Tenant shall indemnify each other against and hold the other harmless from all liabilities, claims, and expenses (including reasonable attorney’s fees) arising out of a breach of their respective warranty. Landlord shall pay a commission to
Grant Street Associates pursuant to a separate agreement between Landlord and Grant Street Associates. 
  

 16 








 20. Exhibit I. The parties agree that Exhibit I attached to the Fifth Amendment is hereby
deleted, and Exhibit I attached hereto (which reflects changes to the schedule of tenant improvement and refurbishment allowances agreed to by the parties in connection with the modifications to the Master Lease set forth in this Amendment) is
hereby substituted into the Master Lease in its place. 
  
 IN WITNESS WHEREOF, this Sixth Amendment has been duly executed by the parties hereto as of the date first above written.

 FOURTH AMENDMENT TO AGREEMENT OF LEASE 
 FOR PREMISES IN THE FEDERATED INVESTORS TOWER 
  
 THIS FOURTH AMENDMENT TO AGREEMENT OF LEASE (this “Amendment”) is made and entered into the 30th day of June, 2000, by and between LIBERTY
CENTER VENTURE, a Pennsylvania general partnership (“Landlord”), and FEDERATED INVESTORS, INC. (“Tenant”). 
  
 WITNESSETH 
  
 Whereas, Landlord and Tenant are parties to an Agreement of Lease for certain premises in the Federated Investors Tower dated as of the 1st day of
January, 1993, as amended by an Amendment dated May 1, 1995, a First Amendment dated November 2, 1995, a Second Amendment dated September 19, 1996, and a Third Amendment dated February 10, 1999 (the “Master Lease”); and 
  
 Whereas, Tenant has requested permission to install two (2) signs (the
“Signs”) at the Premises; and 
  
 Whereas, Landlord is
willing to permit the installation of the Signs subject to certain restrictions and approvals as hereinafter set forth; and 
  
 NOW THEREFORE, in consideration of the sum of One Dollar ($1.00), other good and valuable consideration and of the agreement of the parties hereinafter
set forth, Landlord and Tenant hereby agree as follows: 
  
 1. The Signs shall be
of the size, style and composition as described in the construction plans (the “Plans”) contained in the proposal submitted by Federated Investors, the Design Alliance Architects, the Kachele Group and Dynamic Design Engineering, Inc. (the
“Proposal”) which is incorporated herein by reference. 
  
 2. Landlord
shall have the right, but not the obligation to review and approve the final plans (“Final Plans”), which approval shall not be unreasonably withheld. 
  

3. The Signs must be installed by a professional installer in strict accordance with the Proposal and the Final Plans at Tenant’s sole cost and expense. Tenant
further agrees that maintenance and operation of the sign is at Tenant’s sole cost and expense. 
  









 4. Tenant acknowledges that the roof of the Premises contains lighting fixtures which illuminate the existing preformed
metal roof. Tenant shall ensure that the installation of the Signs shall not interfere with such illumination and that such lighting shall remain functional and in use for various occasions, including “Light Up Nights”. 
  
 5. Before installing the Signs and so long as the Signs are in place, Tenant must maintain
public liability insurance acceptable to Landlord in the amount of at least $1,000,000.00 on a combined single limit per occurrence basis for property damage and personal and bodily injury or death which names Landlord and Owner as additional
insureds. Tenant must furnish Landlord with a certificate of insurance proving compliance with the foregoing which also states that the insurance will not be changed or terminated without at least 30 days prior written notice to Landlord and Owner.
Tenant shall furnish Landlord with replacement certificates before the expiration of the current certificate. 
  
 This requirement shall not be construed to require an additional $1,000,000.00 of insurance above the insurance requirements in the Lease, but represents
the minimum amount of insurance the Tenant shall carry. 
  
 6. Tenant hereby
agrees to indemnify and save and hold harmless Landlord, Owner and their respective employees from all loss, cost and expense, including, without limitation, attorney fees arising out of or by reason of Tenant’s installation, use, enjoyment and
removal of the Signs whether foreseen or unforeseen. This indemnity is intended to be interpreted as broadly as possible to protect Landlord and Owner and their employees. 
  
 7. The Signs shall be installed and operated in accordance with all applicable laws and regulations. Tenant shall be responsible for any
interference caused or generated by the Signs. Landlord and Owner shall not be liable in any manner by reason of their approval of the Final Plans or the Proposal and Tenant assumes all such liability and is solely responsible for the Final Plans
and Proposal and the compliance of the Final Plans and Proposal with all applicable laws and regulations. 
  
 8. Tenant acknowledges that in the event Tenant’s occupancy level decreases below the square footage covered by the Master Lease. Landlord may, at Landlord’s sole option and sole discretion require Tenant to
pay commercially reasonable rent for the sign space at a price to be 

  

 2 








 
mutually agreed upon by the parties acting in good faith at that time or if no agreement is reached, Tenant will remove the sign. 
  
 9. Tenant acknowledges and agrees that should the Signs be removed at any time and for any
reason, Tenant shall repair all damage caused by the removal and shall restore the Premises to its prior condition before the installation of the Signs, including restoration of the existing preformed metal roof at Tenant’s sole cost and
expense. 
  
 10. Applicable Law. The laws of the Commonwealth of
Pennsylvania shall govern the validity, performance and enforcement of this Amendment. The invalidity or unenforceability of any provision of this Amendment shall not affect or impair any other provision. 
  
 11. Interpretation. In the event of any conflict between the provisions of the Master
Lease and the provisions of this Amendment, the provisions of this Amendment shall control. As amended hereby, all of the terms, covenants and conditions of the Master Lease as heretofore in effect shall remain in full force and effect after the
date hereof and are hereby ratified and confirmed in all respects. 
  
 12.
Execution. This Amendment may be signed in counterparts, each of which shall be deemed an original, but all of which shall be deemed but one and the same instrument. 
  
 IN WITNESS WHEREOF, this Amendment has been duly executed by the parties hereto as of the date first above written.
