 (l) Section 24 of the Partnership Agreement is hereby amended by deleting same in its entirety and
inserting in lieu thereof the following: 
  
 “SECTION 24. Debt Maintenance Requirement, Transfer Indemnity.  
  
 (a) If during the Restrictive Period the Partnership does not maintain an amount of non-recourse indebtedness secured by the 35 W. Wacker
Property and cause such portion of such indebtedness to be allocated to LBC under Code §752 and the regulations thereunder that is sufficient to protect LBC against recognizing gain pursuant to Code § 731(a)(1) as a result of a deemed
distribution of money to LBC pursuant to Code § 752(b) (the “Debt Maintenance Requirement”), then the Partnership shall indemnify LBC in the manner provided in Section 25(b) herein. As of the Amendment Effective Date the Debt
Maintenance Requirement is equal to the amount set forth on Schedule IV hereto, as the same may be amended from time to time with the consent of LBC which shall not be unreasonably withheld. The Debt Maintenance Requirement shall terminate
(and, as such, shall be zero) as of the end of the Restrictive Period. 
  
 (b) If during the Restrictive Period the Partnership (or any successor thereto) refinances, sells, transfers, or in any other manner alters the ownership structure or ownership entity of the 35 W. Wacker Property in
any manner that could cause adverse tax consequences to LBC in the reasonable opinion of LBC’s tax counsel, Kirkland & Ellis (or such other counsel as may be reasonably approved by the Partnership) then the Partnership shall indemnify LBC
in the manner provided in Section 25(b) herein (the “Transfer Indemnity”). The General Partner shall provide notice to LBC within thirty (30) days of the occurrence of an event that could trigger the Transfer Indemnity. 

 
 (c) Notwithstanding the foregoing provisions of this
Section 24, the Debt Maintenance Requirement and Transfer Indemnity shall cease to apply, and the Restrictive Period shall terminate, if LBC has voluntarily and independently recognized its taxable gain resulting from the transfer of the 35 W.
Wacker Property to the Partnership or has defaulted in the payment of rent or other material economic obligations under the LBC Lease and such default has remained uncured for a period of sixty (60) days following written demand therefor.”

  
 (m) Section 25 of the Partnership Agreement is hereby amended
and restated in its entirety as follows: 
  
 “SECTION 25. Tax Indemnity.  
  
 (a) The Partnership hereby agrees to indemnify, defend, and hold harmless LBC and its parent companies (the “LBC Indemnitees”), on a net after-tax basis, against the adverse U.S. Federal income tax impact to
the LBC Indemnitees of the Partnership’s use of the Remedial Method during the tax years ending December 31, 2003 and December 31, 2004, the “Remedial Indemnification Amount”. The Partners agree that the Remedial
Indemnification Amount for the Taxable Year ending December 31, 2003, payable on January 14, 2004, shall be $363,490.00 and for the Taxable Year ending December 31, 2004, payable on January 14, 2005, shall be $334,264. There shall be no Remedial
Indemnification Amount payable for any tax year ending after December 31, 2004. 
  

 7 

 (b) (i) In the event that during the Restrictive Period, (1) the Partnership does not
satisfy the Debt Maintenance Requirement, (2) the Transfer Indemnity is applicable or (3) Wells exercises its Drag-Along rights pursuant to Section 18(b) herein (each such action, an “Event”), the Partnership hereby agrees to pay LBC a
one-time indemnity payment as a result of the LBC Indemnitees having to pay the U.S. Federal and Illinois state income tax attributable to the taxable gain recognized by (or allocated to) LBC resulting solely from an Event occurring prior to the end
of the Restrictive Period (regardless of when such determination of recognition or allocation occurs) in the applicable amount set forth on Schedule III attached hereto (the “Transfer And Debt Maintenance Indemnity Amount”)
for the Taxable Year in which the Event actually occurred; provided, however, if on or before the date for the filing of the Partnership’s U.S. Federal income tax return for the Taxable Year during which the Event occurs, the
Partnership obtains an opinion of counsel (reasonably acceptable to LBC) or a ruling from the United States Internal Revenue Service (the “IRS”), to the effect that LBC should not recognize any taxable income or gain under Code §
704(c), Code § 731(a) or Code § 1001(a) (or any successor statutes or under such other Code Sections designated by LBC tax counsel and identified to Wells within ten (10) Business Days of the notice to LBC required by Section 24(b))
resulting solely from such Event, then there shall be no Transfer And Debt Maintenance Indemnity Amount payable by the Partnership to LBC with respect thereto, subject to the provisions of (b) (ii) below. LBC agrees to cooperate with Partnership tax
counsel, with all reasonable out-of-pocket costs at the expense of the Partnership, in connection with obtaining any such ruling or opinion. 
  
 (ii) The Partnership will furnish LBC with a copy of any such opinion of counsel or ruling described in Section 25(b)(i) above promptly
upon the Partnership’s receipt thereof, and in any case with ten (10) Business Days prior to the time the LBC Indemnitees are required to pay U.S. corporate estimated Federal income taxes in respect of the Event, as contemplated in Section
25(b)(iii) below, or, if earlier, the time they are required to file any returns recognizing the income or gain from the Event. If the Partnership obtains an opinion of counsel described in Section 25(b)(i) above each LBC Indemnitee agrees that it
will not take any position on its returns, on audit or otherwise in connection with its tax liability for U.S. Federal or state tax purposes that is inconsistent with such opinion. If any LBC Indemnitee receives a notice of a claim or if at the
conclusion of an audit by the IRS or other state taxing authority, there is a proposed adjustment in any item of income or gain, which if agreed to or accepted by any LBC Indemnitee would result in an indemnity obligation pursuant to Section
25(b)(i) hereof, then LBC shall promptly after receipt of such notice or promptly upon conclusion of such audit, notify the Partnership thereof in writing. If requested by the Partnership, LBC shall in good faith contest, or permit the Partnership
to contest, the validity, applicability or amount of any proposed adjustment that would give rise to the payment of all or a portion of the Transfer And Debt Maintenance Indemnity Amount by (1) not making payment thereof for at least 30 days after
providing the Partnership the notice required by this Section 25(b)(ii), unless otherwise required by applicable law or regulations, (2) not paying same except under protest, if protest is necessary and proper, or (3) if payment is 

  

 8 

 
made, using reasonable efforts to obtain a refund thereof in appropriate administrative and judicial proceedings. LBC shall not be required to contest the
proposed adjustment unless and until the Partnership has agreed to pay all reasonable out-of-pocket costs and expenses which LBC incurs in connection with contesting such adjustment. If LBC controls such contest, LBC agrees to consult with the
Partnership and will consider in good faith any suggestions made by the Partnership with respect to the most favorable forum for and the conduct of such contest and will enable the Partnership’s representative to participate in any proceeding.
If requested by the Partnership, LBC agrees to appeal any adverse determination but LBC shall not be required to appeal any adverse determination to the United States Supreme Court. LBC shall not have the right to settle or compromise a contest
without the Partnership’s consent, which consent shall not be unreasonably withheld, unless LBC agrees to forego its right to an indemnity hereunder. If any LBC Indemnitee receives a refund of all or part of any U.S Federal or state income
taxes paid solely in respect of an Event for which any Transfer And Debt Maintenance Indemnity Amount is paid by the Partnership (or if any LBC Indemnitee would have received a refund but for other adjustments or offsets not related to the Event),
LBC shall pay to the Partnership an amount equal to the product of (a) the Transfer And Debt Maintenance Indemnity Amount paid by the Partnership with respect to such Event multiplied by (y) a fraction the numerator of which is the sum of such
refund (or the amount such refund would have been but for such other adjustments or offsets), plus any interest received on such refund, net of any U.S. Federal or state income taxes imposed on the LBC Indemnitees as a result of such refund, and the
denominator of which is the total amount of U.S. Federal or state income taxes paid or payable by the LBC Indemnitee related to such Event. LBC may at any time decline to take further action with respect to a proposed adjustment by notifying the
Partnership in writing that it has waived its right to an indemnity payment that would otherwise be payable by the Partnership pursuant to this Section 25(b). Likewise, the Partnership may at any time request that LBC decline to take any further
action by agreeing in writing to pay the Transfer And Debt Maintenance Indemnity Amount, provided that in such event LBC may still pursue such action at its own expense and without further applicability of the provisions of this Section 25(b)(ii).
Any failure of LBC to comply with the requirements of this Section 25(b)(ii) shall relieve the Partnership of any obligation to pay the Transfer And Debt Maintenance Indemnity Amount to the extent that the ability to contest a claim pursuant to the
provisions of this Section 25(b)(ii) is adversely affected in any material respect. 
  
 (iii) The Transfer And Debt Maintenance Indemnity Amount, if any, shall be due and payable by the Partnership as of the corporate
estimated tax payment date following the Event giving rise to an indemnity obligation hereunder. Notwithstanding the foregoing, if the Partnership has provided LBC an opinion pursuant to Section 25(b)(i) hereof, any Transfer And Debt Maintenance
Indemnity Amount, if any, shall be due and payable by the Partnership within 30 days after receipt of a written demand therefor from LBC; provided, however, the Partnership shall not be required to make such payment earlier than (1) in
the case of a Transfer And Debt Maintenance Indemnity Amount that is not being contested pursuant to Section 25(b)(ii) hereof, five (5) Business Days prior to the date that the LBC Indemnitees are required to pay such estimated tax, or (2) in the
case of a Transfer And Debt Maintenance Indemnity Amount that is being contested pursuant to Section 25(b)(ii) hereof, 30 days after the date of the Final Determination of such contest. 
  

 9 

 A “Final Determination” shall mean (i) a decision, judgment, decree or other order by any court
of competent jurisdiction, which decision, judgment, decree or other order has become final after all allowable appeals by either party to the action have been exhausted or the time for filing such appeals has expired, (ii) a closing agreement
entered into under section 7121 of the Code or any other settlement agreement entered into in connection with an administrative or judicial proceeding and with the consent of the Partnership hereof, (iii) the expiration of the time for instituting
suit with respect to the claimed deficiency or (iv) the expiration of the time for instituting a claim for refund, or if such a claim was filed, the expiration of the time for instituting suit with respect thereto. 
  
 (c) The Partnership agrees to indemnify, defend and hold
harmless the LBC Indemnitees, on a net after-tax basis, against the adverse tax impact to the LBC Indemnitees, if any, of the conversion of the Original Company from a limited liability company to a limited partnership and the admission of VV
City-Buck as the General Partner of the Partnership (the “Conversion Indemnification Amount”). The Conversion Indemnification Amount shall be computed based on the assumption that LBC is a U.S. corporation paying U.S. and Illinois
state income taxes at the maximum marginal rates, but adjusted to reflect a full deduction for state income taxes without limitation. 
  
 (d) Notwithstanding the foregoing provisions of this Section 25, all of the foregoing tax indemnification obligations shall terminate, if
and when LBC has voluntarily and independently recognized its taxable gain resulting from the transfer of the 35 W. Wacker Property to the Partnership or has defaulted in the payment of rent or other material economic obligations under the LBC Lease
and such default has remained uncured for a period of sixty (60) days following written demand therefor. The payment of indemnification under this Section 25 and the Guaranty shall be the sole remedy available to LBC in respect of the
Partnership’s election to use the Remedial Method, the Partnership’s failure to satisfy the Debt Maintenance Requirement, the occurrence of an Event described in Section 25(b) and/or if the Conversion Indemnification Amount becomes
payable. 
  
 (e) Notwithstanding anything herein
to the contrary, no Transfer And Debt Maintenance Indemnity Amount shall be payable to LBC as a result of (i) the transfer of the general partner interest in the Investor Partnership by VV USA to Wells and the admission of Wells as the general
partner of the Investor Partnership, (ii) the Sale of all or any part of LBC’s Partnership Interest pursuant to any exercise by LBC (or its successor) of the “tag along” right under Section 18(b) herein, (iii) any exercise of the
“put” by LBC (or its successor) or any exercise of the “call” by Wells (or its successor) under the Put And Call Agreement, or (iv) the entering into of the First Amendment to the Second Amended and Restated Limited Partnership
Agreement of 35 W. Wacker Venture, L.P. No Transfer And Debt Maintenance Indemnity Amount shall be payable to any assignee of LBC’s Partnership Interest under Section 18(d) other than an Affiliate of LBC.”

 EXHIBIT C-1 
  
 [Form of Wells OP Guaranty] 

 GUARANTY OF PAYMENT 
  
 This Guaranty of Payment (“Guaranty”), made as of the      day of
                , 2003, by Wells Operating Partnership, L.P., a Delaware limited partnership (“Guarantor”), to and for the benefit of Leo Burnett USA,
Inc. (f/k/a Leo Burnett Company, Inc.) (“LBC”). 
  
 R E C I T A L S: 
  
 A. LBC and Wells-Buck Venture, L.P. (“Wells-Buck”) have entered into that certain Second Amended and Restated Limited Partnership Agreement of 35 W. Wacker Venture, L.P. dated as of April 27, 2000 (the
“2000 LPA”), as amended by that certain First Amendment to the Second Amended and Restated Limited Partnership Agreement of 35 W. Wacker Venture, L.P. (the “First Amendment”; said 2000 LPA, as so amended by the First Amendment,
being herein referred to as the “Partnership Agreement”). 
  
 B. The Partnership Agreement requires that 35 W. Wacker Venture, L.P. (the “Partnership”) indemnify LBC for certain tax liabilities as set forth therein. 
  
 C. The Partnership Agreement also requires that such indemnification shall be guaranteed by Guarantor. 
  
 D. Capitalized terms used herein and not expressly defined herein shall have
the meaning given them in the Partnership Agreement. 
  
 NOW,
THEREFORE, in consideration of the premises and for other good and valuable consideration, the receipt and adequacy of which is hereby acknowledged, Guarantor agrees as follows: 
  
 1. Guaranty. Guarantor absolutely, unconditionally and irrevocably guarantees to LBC: 
  
 (a) the full and prompt payment when due, upon acceleration or otherwise,
and at all times thereafter, of any and all debts, liabilities and obligations of the Partnership and Wells-Buck under Section 25 of the Partnership Agreement (the Transfer And Debt Maintenance Indemnity Amount, the Remedial Indemnification Amount
and the Conversion Indemnification Amount collectively referred to as the “Indemnity Obligations”), however created, arising or evidenced, whether direct or indirect, absolute or contingent, now or hereafter existing, due or to become due,
known or unknown to Guarantor at the time of the execution of this Guaranty; and 
  
 (b) the payment of all Enforcement Costs (as hereinafter defined). 
  
 All amounts due, debts, liabilities and payment obligations described in subparagraphs (a) and (b) of this Paragraph 1 are collectively referred to herein
as the “Indebtedness.” 
  
 2. LBC’s
Remedies. In the event the Partnership or Wells-Buck fails to timely pay to LBC the amounts due pursuant to the Indemnity Obligations, Guarantor agrees, on demand by LBC but subject to the conditions set forth in Section 25 of the
Partnership Agreement, to pay all 

 
remaining sums guaranteed or due hereunder regardless of any other defense, right of set-off or claims which the Partnership, Wells-Buck or Guarantor may
have against LBC except under such Section 25 of the Partnership Agreement or under Paragraph 3 of the First Amendment. Subject to the foregoing, this is an absolute, irrevocable, present and continuing guaranty of payment and not of collection, and
in any action to enforce this Guaranty, LBC, at its election, may proceed against Guarantor, with or without: (i) joining the Partnership or Wells-Buck in any such action; or (ii) commencing any action against or obtaining any judgment against the
Partnership or Wells-Buck. 
  
 3. Extension and
Reinstatement of Guaranty. This Guaranty shall continue to be effective, or be reinstated, as the case may be, if at any time any whole or partial payment of the Indebtedness is or is sought to be rescinded or must otherwise be restored or
returned by LBC upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Partnership, Wells-Buck or Guarantor or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar
officer for the Partnership, Wells-Buck or Guarantor, all as though such payments had not been made. Without limiting the generality of the foregoing, this Guaranty shall remain in full force and effect, until the earlier to occur of: one (1) year
after the date upon which LBC shall have received full payment of all Indemnity Obligations and all other sums due and owing under this Guaranty and for so long thereafter as there is pending against the Partnership, Wells-Buck or Guarantor a
proceeding under any federal or state bankruptcy or insolvency laws, and (ii) termination of the Indemnity Obligations in accordance with the terms of Section 25 of the Partnership Agreement. This Guaranty shall not be affected in any way by the
transfer or other disposition of the Property whether by deed, operation of law or otherwise. 
  
 4. No Discharge. Subject to the provisions of Section 25 of the Partnership Agreement, Guarantor agrees that the obligations, covenants and agreements of Guarantor under this Guaranty shall not be
affected or impaired by any act of LBC, or any event or condition except payment in full of the Indebtedness and any other sums due hereunder. 
  
 5. Waiver. Guarantor expressly waives: (i) notice of the acceptance by LBC of this Guaranty; (ii) notice of the existence, creation, payment
or nonpayment of the Indebtedness; (iii) presentment, demand, notice of dishonor, protest, and all other notices whatsoever; and (iv) the right to trial by jury in any action to enforce this Guaranty. No modifications or waiver of any of the
provisions of this Guaranty will be binding upon LBC except as expressly set forth in a writing duly signed and delivered on behalf of LBC. 
  
 6. Enforcement Costs: If due to breach or failure to pay or perform by Guarantor hereunder: (i) this Guaranty is placed in the hands of one
or more attorneys for collection or is collected through any legal proceeding; (ii) one or more attorneys is retained to represent LBC in any bankruptcy, reorganization, receivership or other proceedings affecting creditors’ rights and
involving a claim under this Guaranty; or (iii) one or more attorneys is retained to represent LBC in any other proceedings whatsoever in connection with this Guaranty, then Guarantor shall pay to LBC upon demand all attorneys’ fees, costs and
expenses, including, without limitation, court costs, filing fees and all other costs and expenses incurred in connection therewith (all of which are referred to herein as “Enforcement Costs”), in addition to all other amounts due
hereunder. 
  

 C-2 

 7. Governing Law; Interpretation. This Guaranty has been negotiated, executed and
delivered in Chicago, Illinois, and shall be governed by the laws of the State of Illinois without reference to the conflicts of law principles of that State. The headings of sections and paragraphs in this Guaranty are for convenience only and
shall not be construed in any way to limit or define the content, scope or intent of the provisions hereof. As used in this Guaranty, the singular shall include the plural, and masculine, feminine and neuter pronouns shall be fully interchangeable,
where the context so requires. If any provision of this Guaranty, or any paragraph, sentence, clause, phrase or word, or the application thereof, in any circumstances, is adjudicated by a court of competent jurisdiction to be invalid, the validity
of the remainder of this Guaranty shall be construed as if such invalid part were never included herein. Time is of the essence in this Guaranty. All payments to be made hereunder shall be made in currency and coin of the United States of America
which is legal tender for public and private debts at the time of payment. 
  
 8. Entire Agreement. The provisions of the Partnership Agreement pertaining to the Indemnity Obligations and this Guaranty thereof constitute the entire agreement between the parties with respect
to the subject matter hereof and supersede all prior such agreements and understandings, both written and oral. This Guaranty may not be modified or amended except by a written instrument signed by LBC and Guarantor. If this Guaranty is executed in
several counterparts, each of those counterparts shall be deemed an original, and all of them together shall constitute one and the same instrument. 
  
 9. Prohibitions on Loans or Advances. Guarantor hereby represents and warrants to LBC that neither Guarantor nor Wells 35 W. Wacker,
LLC has made any loans or other advances to the Partnership or Wells-Buck which have not been previously paid in full, and Guarantor agrees not to make, or permit Wells 35 W. Wacker, LLC to make, any loan or advance to the Partnership for so long as
this Guaranty remains in effect unless such loan is subordinated in right of payment to any obligation owing under this Guaranty. Nothing in the foregoing sentence, however, is intended or shall be deemed to preclude a contribution to capital,
equity investment in common stock or other infusion of at risk funds in the Partnership. 
  
 10. Payment of Indemnity Obligations. LBC agrees that the obligations of Guarantor under this Guaranty shall terminate, subject to the provisions of Paragraph 3 hereof, upon the earlier to occur
of: (i) one (1) year after the date upon which LBC shall have received full payment of all Indemnity Obligations and all other sums due and owing under this Guaranty; and (ii) termination of the Indemnity Obligations in accordance with the terms of
Section 25 of the Partnership Agreement. 
  
 11. Waiver of
Indemnification and Other Rights. Guarantor hereby unconditionally and irrevocably agrees that (i) Guarantor will not assert at any time against the Partnership or Wells-Buck (or the estate of the Partnership or Wells-Buck if the
Partnership or Wells-Buck becomes bankrupt or becomes the subject of any case or proceeding under the bankruptcy laws of the United States of America) any right or claim to indemnification, reimbursement, contribution or payment for or with respect
to any and all amounts and liabilities which Guarantor may pay or perform or be obligated to pay to or perform on account of the Indebtedness under or with respect to this Guaranty; provided that any payment made by Guarantor to LBC hereunder shall
be treated as a Capital Contribution to the Partnership 

  

 C-3 

 
pursuant to Section 8(b) thereof; and (ii) subject to the foregoing, Guarantor waives and releases all such rights and claims to indemnification,
reimbursement, contribution or payment which Guarantor may have now or at any time against the Partnership or Wells-Buck (or the estate of the Partnership or Wells-Buck if the Partnership or Wells-Buck becomes bankrupt or becomes the subject of any
case or proceeding under the bankruptcy laws of the United States of America). Guarantor further unconditionally and irrevocably agrees that it shall have no right of subrogation with respect to, and hereby waives any right to enforce, any remedy
which LBC now has or may hereafter have against the Partnership or Wells-Buck, or any security now or hereafter held by LBC. Subject to Paragraph 2 of this Guaranty, Guarantor also waives any defense based upon an election of remedies by LBC which
destroys or otherwise impairs any subrogation rights of Guarantor or the right of Guarantor to proceed against the Partnership or Wells-Buck for reimbursement, or both. All laws exempting real or personal property from execution are hereby waived,
and no benefit of exemption will be claimed under or by virtue of any exemption law now in force or which hereafter may be passed. 
  
 12. Additional Representations and Warranties. In addition to and independent of any other obligation or liability under this
Guaranty, Guarantor hereby represents and warrants to LBC as follows: 
  
 (a) Guarantor has an indirect economic investment or interest in the Partnership, an indirect economic investment or interest in Wells-Buck and an interest in the success of the Partnership, Wells-Buck and Wells 35 W. Wacker, LLC;

  
 (b) Any and all balance sheets, net worth statements and other
financial data with respect to Guarantor which have heretofore been given to LBC by or on behalf of Guarantor fairly and accurately present the financial condition of Guarantor as of the respective dates thereof and, since the respective dates
thereof, there has been no material adverse change in the financial condition of Guarantor; 
  
 (c) The execution, delivery and performance by Guarantor of this Guaranty do not and will not contravene or conflict with (i) any law, order, rule, regulation, writ, injunction or decree now in effect of any
government, governmental instrumentality or court having jurisdiction over Guarantor, or (ii) any contractual restriction binding on or affecting Guarantor or any of Guarantor’s property or assets unless appropriate consents have been obtained
prior to execution hereof; 
  
 (d) This Guaranty creates legal,
valid and binding obligations of Guarantor enforceable against Guarantor in accordance with its terms subject to bankruptcy, creditors’ rights, and insolvency; 
  
 (e) There is no action, proceeding or investigation pending or, to the knowledge of Guarantor, threatened, affecting
Guarantor, which may adversely affect the ability of Guarantor to pay the Indemnity Obligations in full and to fulfill and perform the other undertakings under this Guaranty; and 
  
 (f) No representation or warranty by Guarantor contained herein, nor any schedule, certificate or other document furnished
by Guarantor to LBC in connection with this Guaranty contains any material misstatement of fact or omits to state a material fact or any fact necessary to make the statements contained therein not misleading. 
  

 C-4 

 (g) Guarantor hereby indemnifies LBC and agrees to defend and hold harmless LBC from and against: (a) any
loss, cost, damage or expense occurring by reason of a breach of the foregoing representations and warranties; and (b) the loss, mitigation, subordination or other consequences adverse to LBC by reason of this Guaranty being challenged as a
preference or suffering any other subjugation under any bankruptcy or other law, whether state or federal, affecting debtors, creditors and/or the relationship between and among them, provided that in any event Guarantor’s maximum obligation
under this Guaranty at any time shall not exceed the amount of the Indebtedness which Guarantor may have under Paragraph 1. 
  
 13. Successors and Assigns; Joint and Several Liability. This Guaranty shall bind Guarantor and the heirs, assigns, successors, executors,
administrators and legal and personal representatives of Guarantor; provided that Guarantor shall not be entitled to transfer or assign its obligations hereunder without the prior written consent of LBC. If this Guaranty is executed by more than one
person, it shall be the joint and several undertaking of each of the undersigned. Regardless of whether this Guaranty is executed by more than one person, it is agreed that the undersigned’s liability hereunder is several and independent of any
other guarantees or other obligations at any time in effect with respect to the Indemnity Obligations or any part thereof and that Guarantor’s liability hereunder may be enforced regardless of the existence, validity, enforcement or
non-enforcement of any such other guarantees or other obligations. LBC shall have the right to assign its rights under this Guaranty to any Affiliate to which LBC transfers its interest in the Partnership pursuant to the Partnership Agreement.

  
 14. Agent for Service of Process. Guarantor
hereby submits to personal jurisdiction in the State of Illinois for the enforcement of this Guaranty and waives any and all personal rights to object to such jurisdiction for the purposes of litigation to enforce this Guaranty. In the event such
litigation is commenced at any time when Guarantor is not permanently domiciled in the State of Illinois, Guarantor agrees that service of process may be made and personal jurisdiction over Guarantor obtained, by service of a copy of the summons,
complaint and other pleadings required to commence such litigation upon the appointed agent for service of process in the State of Illinois, which agent Guarantor hereby designates to be: 
  
 CT Corporation System 
 208 S. LaSalle Street, Suite 814 
 Chicago, Illinois 60604 
  
 Guarantor agrees that this appointment of an agent for service of process is made for the mutual benefit of Guarantor and LBC and may not be
revoked without LBC’s consent. Guarantor hereby agrees and consents that any such service of process upon such agent shall be taken and held to be valid personal service upon Guarantor, whether or not Guarantor shall be then physically present,
residing within, or doing business within the State of Illinois, and that any such service of process shall be of the same force and validity as if service were made upon Guarantor when physically present, residing within, or doing business in the
State of Illinois. Guarantor waives 

  

 C-5 

 
all claim of error by reason of any such service. Guarantor hereby consents to the jurisdiction of either the Circuit Court of Cook County, Illinois, or the
United States District Court for the Northern District of Illinois, in any action, suit or proceeding which LBC may wish to file at any time in connection with this Guaranty or any related matter. Guarantor hereby agrees that an action, suit or
proceeding to enforce this Guaranty may be brought in any state or federal court in the State of Illinois and hereby waives any objection which Guarantor may have to the laying of the venue of any such action, suit or proceeding in any such court;
provided, however, that the provisions of this Paragraph shall not be deemed to preclude LBC from filing any such action, suit or proceeding in any other appropriate forum. 
  
 15. Notices. All notices, demands, requests, or other communications which may be or are required to be given,
served, or sent by any party to any other party pursuant to this Agreement shall be in writing and shall be hand delivered, sent by overnight courier or mailed by first-class, registered or certified mail, return receipt requested, postage prepaid,

by that certain First Amendment to Limited Partnership Agreement of VV City-Buck Venture, L.P., dated as of March 10, 2003 (the “First Amendment”) (the initial agreement of limited partnership, as amended by the First Amendment, the

 C. WHEREAS, Wells and JBC desire to amend, restate and replace the Original
Partnership Agreement in its entirety to reflect, among other changes, the sale and transfer of the GP Interest to Wells, the withdrawal of VV City as the general partner of the Partnership, the admission of Wells as the sole general partner of the

 NOW, THEREFORE, in consideration of the promises and the mutual covenants set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto,
intending to be legally bound, do hereby agree as follows: 
  
 SECTION 1.
Continuation of Limited Partnership. The Partners agree to continue the Partnership which was formed pursuant to the Act and the filing of the Certificate of Limited Partnership of the Partnership with the Secretary on April 12, 2000, and
agree that for purposes of the Act and this Agreement the Partnership was not and shall not be deemed to have dissolved as a result of any of the matters described in Recital C above. Wells is authorized to file with the Secretary an amendment to

Partnership determined immediately prior to the contribution reduced (but not below zero) by two times the amount of the Capital Contribution that such Defaulting Partner shall have failed to contribute, and the denominator of which is the total
Notional Value of the investments of all of the Partners in the Partnership (determined immediately before the contribution), and the Partnership Interest of the Non-defaulting Partner immediately after the contribution shall be equal to 100%

Partner shall receive back its Capital Contribution and may loan to the Partnership an amount equal to the amount received plus the Defaulting Partner’s pro rata share of such requested Capital Contributions, and the Non-defaulting Partner
shall designate such loan as a Priority Loan. Priority Loans shall bear interest at the cumulative annual interest rate of 20%, compounded quarterly on the average daily outstanding balance, and shall be paid out of any distributions payable to the
Partners pursuant to and in accordance with Section 9 of this Agreement. Interest expense incurred on any Priority Loan shall be treated as an expense of the Partnership and shall be non-recourse to individual Partners. Payments on Priority Loans

cases not covered by Section 8(b)(i) shall be as follows.

sole and exclusive remedy, to either (i) withdraw the Requested Amount which it contributed; or (ii) confirm that the amount contributed by it is a Capital Contribution and contribute the Deficiency to the Partnership as a Capital Contribution for
its own capital account.

Partnership for its own capital account and to contribute to the Partnership as an additional Capital Contribution for its own capital account the Deficiency as provided in Subsection 8(b), then, effective from the date of the making of such
contribution, the Partnership Interests of the Partners shall thereupon be recalculated such that, immediately after such recalculation, the Partnership Interest of each of the Partners shall equal a percentage, the numerator of which is the
Notional Value of such Partner’s investment in the Partnership (determined immediately after the contribution), and the denominator of which is the total Notional Value of the investments of all of the Partners in the Partnership (determined

participating in the meeting can hear each other, and such participation shall constitute presence in person at the meeting. The Partnership shall give written notice of the date, time, place and purpose of any meeting to all Partners at least ten
(10) days and not more than sixty (60) days prior to the date fixed for the meeting. Notice may be waived by any Partner. 
  
 (b) Consent of Partners. Any action required or permitted to be taken at any meeting of Partners may be taken by a written consent without a
meeting, without prior notice and without a vote. The written consent shall set forth the action so taken and shall be signed by Partners having not less than the minimum number of Percentage Interests that would be necessary to authorize or take
such action at a meeting at which all Partners entitled to vote thereon were present and voting. Prompt notice of the taking of action by written consent shall be given to all Partners who did not sign the written consent.

 SECTION 16. Voting. 
  
 (a) Partners. The General Partner shall decide all matters for the Partnership and need not call any meeting of the
Partners prior to taking action; provided, if the General Partner shall at any time own less than a Majority Interest, the affirmative vote or written consent of a Majority Interest shall decide all matters properly brought before the Partners

violation of applicable environmental laws and any decisions regarding the remediation or removal of any such hazardous waste that is present at the 35 W. Wacker Property in violation of applicable environmental laws. Notwithstanding the foregoing,
during such time as JBC Management is the property manager for the 35 W. Wacker Property, the General Partner need not advise the Limited Partner with respect to the decisions discussed in clauses (v), (vi) and (vii) of the preceding sentence.

  
 (b) Voting. A Partner may vote either in person or by
written proxy or consent signed by the Partner or by his duly authorized attorney in fact. 
  
 SECTION 17. Exculpation, Limitation of Liability and Indemnification. 
  
 (a) Exculpation. Notwithstanding anything to the contrary set forth in this Agreement, neither the General Partner nor any Limited Partner shall be
liable to the Partnership or to any other Partner for monetary damages for any losses, claims, damages or liabilities arising from any act or omission of such General Partner or Limited Partner arising out of or in connection with this Agreement or
the Partnership’s business or affairs, except to the extent that such act or omission (1) is attributable to such General Partner’s or Limited Partners fraud, bad faith, willful misconduct or gross negligence or (2) was clearly outside the
scope of authority granted to such General Partner or Limited Partner under this Agreement (such acts or omissions being hereinafter referred to as “Excluded Matters”). 
  
 (b) Limitation of Liability. Except as provided in Sections 17-403(b) and (d) of the Act, the debts, obligations and
liabilities of the Partnership, whether arising in contract, tort or otherwise, shall be solely the debts, obligations and liabilities of the Partnership and the General Partner, and no Limited Partner shall be obligated personally for any such
debt, obligation or liability of the Partnership solely by reason of being a Limited Partner. 
  

 15 

 (c) Indemnification. Other than with respect to Excluded Matters, the Partnership shall indemnify,
in accordance with and to the full extent now or hereafter permitted by law, any Person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal,
administrative or investigative (including, without limitation, an action by or in the right of the Partnership) by reason of the fact that such Person is or was a Limited Partner, General Partner or officer of the Partnership or an Affiliate
thereof (and the Partnership may so indemnify a Person by reason of the fact that such Person is or was an employee or agent of the Partnership, or is or was serving at the request of the Partnership as a director, trustee, member, manager, partner
officer, employee or agent of another limited liability company, corporation, partnership, joint venture, trust or other enterprise), against any liabilities, expenses (including, without limitation, attorneys’ fees and expenses and any other
costs and expenses incurred in connection with defending such action, suit or proceeding), judgments, fines and amounts paid in settlement actually and reasonably incurred by such Person in connection with such action, suit or proceeding if such
Person acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Partnership, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct
was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contenders or its equivalent, shall not, of itself, create a presumption (a) that the Person did not act in good faith
or in a manner which he or she reasonably believed to be opposed to the best interests of the Partnership, or (b) with respect to any criminal action or proceeding, that the Person had reasonable cause to believe that his or her conduct was
unlawful. “Other enterprise” shall include employee benefit plans; references to “fines” shall include any excise taxes assessed on a Person with respect to an employee benefit plan; and references to serving at the request of
the Partnership shall include, without limitation, any service as a member, manager, officer, employee or agent of the Partnership or any other entities in which it has an ownership interest which imposes duties on, or invoices services by, such
member, manager, partner, officer, employee or agent with respect to an employee benefit plan, its participants or beneficiaries. 
  
 (d) Expenses. Reasonable expenses, (including, without limitation, attorneys’ fees and expenses) incurred by a Limited Partner, General
Partner or officer of the Partnership in defending a civil, criminal, administrative or investigative action, suit or proceeding shall be paid by the Partnership in advance of the final disposition of such action, suit or proceeding upon receipt of
an undertaking by or on behalf of the Limited Partner, General Partner or officer to repay such amount if it shall ultimately be determined that such Limited Partner, General Partner or officer is not entitled to be indemnified by the Partnership
under this Section 17 or under any other contract or agreement between such Limited Partner, General Partner or officer and the Partnership. Such expenses (including attorneys’ fees) incurred by employees or agents of the Partnership may be so
paid upon the receipt of the aforesaid undertaking and such terms and conditions, if any, as the General Partner deems appropriate. 
  
 (e) Continuation. The indemnification and advancement of expenses provided by this Section 17 shall continue as to a Person who has ceased to be a
Limited Partner, General Partner, officer, employee or agent and shall insure to the benefit of the successors, assigns, heirs, executors and administrators of such a Person. 
  

 16 

 SECTION 18. Sale of Partnership Interests and New Partners. 
  
 (a) Assignment. Except as otherwise permitted in Sections 18(c) and
18(g) herein, any Sale of a Partnership Interest in whole or in part, including, without limitation, pursuant to Section 18(b) shall be permitted only upon compliance with the provisions of Section 18(d) and (e) and, to the extent applicable, upon
compliance with the provisions of Section 18(b) and (g). A Sale of a Partnership Interest shall not entitle the assignee to become or to exercise any rights or powers of a Partner until such assignee is admitted as a Partner in accordance with this
Agreement. As a condition to any Sale of a Partnership Interest, the Partner must notify the assignee and the Partnership in writing of all obligations of such Partner for liabilities relating to the Partnership and this Agreement, including any
obligations to make contributions to the Partnership. Any attempted Sale in contravention of this Section 18 shall be void and of no force or effect except that such Sale shall entitle the transferee only to receive such distributions, to share in
such profits and to receive such allocations of income, gain, loss, deduction, credit, tax preference and similar items to which the transferor was entitled to the extent assigned. 
  
 (b) Tag-Along And Drag-Along Rights. 
  
 (i) Tag-Along. If Wells proposes to effect a Sale to a Person other than: (A) JBC or (B) a Sale to an
Affiliate of Wells of less than fifty percent (50%) of the Partnership Interests held by Wells as of the date hereof, Wells shall offer each and every other Partner the opportunity to sell (the “Tag-Along Purchase Offer”) to such Person
(the “Purchaser”) the Tag-Along Portion of such Partner’s Partnership Interest for the consideration per percentage of Partnership Interest set forth hereinbelow as the “Tag-Along Price” and otherwise in all material
respects on the same terms and conditions upon which Wells sells such portion or all of its Partnership Interest. The Tag-Along Portion shall be the portion of a Partner’s Partnership Interest which is equal to (x) the total Partnership
Interest of such Partner as of the date that the Tag-Along Notice is provided in accordance with clause (iii) below multiplied by (y) a fraction the numerator of which is the Partnership Interest that Wells proposes to sell as set forth in such
Tag-Along Notice and the denominator of which is the total Partnership Interest of Wells as of such date (such portion, the “Tag-Along Portion”). The consideration per percentage Partnership Interest payable to a Partner selling its
Tag-Along Portion will be equal to the amount which would be distributed to such Partner per percentage Partnership Interest assuming the Partnership sold all of its assets for a price which would result in Wells receiving the consideration offered
to Wells in the proposed Sale upon a liquidation of the Partnership. 
  
 (ii) Drag-Along. If Wells proposes to effect a Sale to a Purchaser of all its Partnership Interests, other than: (A) to a Partner or (B) a Sale to an Affiliate of Wells of less than fifty percent (50%) of the
Partnership Interests held by Wells as of the date hereof (the “Drag-Along Purchase Offer”; a Tag-Along Purchase Offer and Drag-Along Purchase Offer may each be referred to herein as a “Purchase Offer”), Wells may require each
and every other Partner to sell to the Purchaser all Partnership Interests held by such 

  

 17 

 
Partners for the same consideration per percentage of Partnership Interest and otherwise on substantially the same terms and conditions upon which Wells
sells its Partnership Interests. 
  
 (iii)
Exercise of Right. In the event of a Purchase Offer, Wells shall cause the Purchase Offer described in clause (i) or (ii) above, as applicable, to be reduced to writing and shall provide a written notice (the “Tag-Along/Drag-Along
Notice”) of the Purchase Offer to the other Partners. The Tag-Along/Drag-Along Notice shall contain written notice, as applicable, of (A) the exercise by Wells of Wells’ drag-along rights pursuant to Section 18(b)(ii), or (B) the Tag-Along
rights of the other Partners to sell the Tag-Along Portion of their Partnership Interests pursuant to Section 18(b)(i), as the case may be, and shall set forth the consideration per percentage of Partnership Interest to be paid by the Purchaser and
the other terms and conditions of the Purchase Offer. No later than 20 days (subject to the expiration of any applicable waiting period under the Hart Scott Rodino Antitrust Improvements Act of 1976) after receipt of a Tag-Along Notice/Drag Along
Notice or in a subsequent notice from Wells (A) in the event of a Drag-Along Purchase Offer, each of the other Partners shall, or (B) in the event of a Tag-Along Purchase Offer, each of the other Partners who elects to participate in such Sale
shall, deliver into escrow with Wells all documents reasonably required to be executed in connection with such Purchase Offer to be held for delivery to the Purchaser upon delivery to such Partner of the consideration therefor. In the event that a
Partner receives a Tag-Along/Drag-Along Notice pursuant to this Section 18(b), such Partner agrees to use commercially reasonable efforts, in good faith and in a timely manner, to take, or cause to be taken, all actions and to do, or cause to be
done, all things necessary, proper or advisable, under applicable laws and regulations (including, without limitation, to ensure that all appropriate legal and other requirements are met and all consents of third Persons are obtained), to consummate
the proposed transactions contemplated by this Section 18(b). Notwithstanding any other provisions of this Section 18(b), in the event of a Drag-Along Sale, no Partner other than the Partner initiating the Drag-Along Sale shall be required to make
any representation or warranty or incur any liability with respect to such Sale other than with respect to (1) such Partner’s clear title to its Partnership Interest; (2) such Partner’s power and authority to complete such sale; and (3)
customary accredited investor and related representations and warranties from such Partner if securities are issued by the Purchaser in connection with the Sale. Each other Partner hereby grants to Wells an irrevocable (to the extent permitted by
law) power of attorney coupled with an interest to execute and deliver any and all documents and instruments on behalf of such other Partner as Wells may deem necessary or appropriate in order to effectuate a Sale pursuant to the provisions of this
Section 18(b). 
  
 (iv) Return of
Documents. If, for any reason, Wells determines that it cannot complete the Sale of the Partnership Interests, Wells shall cause to be returned to the Partners all documents delivered into escrow pursuant hereto by the Partners, and all the
restrictions on Sale or other disposition contained in this Agreement with respect to Partnership Interests shall again be in effect. 
  
 (v) Remittance of Consideration. At the closing of the Sale of Partnership Interest pursuant to this Section 18(b), the
consideration with respect to the Partnership Interests of any Partner sold pursuant hereto shall be paid directly to each Partner pursuant to written instructions of such Partner. 
  

 18 

 (vi) No Liability. Notwithstanding anything contained in this Section 18(b), there
shall be no liability on the part of Wells to any Partner if the Sale of Partnership Interests pursuant to this Section 18(b) is not consummated for whatever reason. Whether to effect a Sale of Partnership Interests held by the Wells (together with
the Partnership Interests of the other Partners pursuant to this Section 18(b)) shall be in the sole and absolute discretion of Wells. 
  
 (c) Put of JBC Limited Partner Interests. 
  
 (i) In the event that (A) the Partnership acquires any material asset other than as required for the continued operation of the
Partnership, 35 West Wacker Venture or the 35 W. Wacker Property without the consent of JBC, or (B) this Agreement or the 35 W. Wacker Venture Agreement is amended without the consent of JBC in the case where such consent is required, as provided in
Section 26(i) below, or (C) if the Partnership elects to use the “remedial method” under Section 1.704-3(d) of the Treasury Regulations following Wells’ acquisition of the GP Interest, then Wells hereby grants JBC the right and option
to require Wells to acquire the entire Partnership Interest of JBC for a purchase price equal to the “Fair Market Value” thereof (such right and option being herein called the “Put”). The Put may be exercised only with respect to
all, and not less than all, of the JBC Partnership Interest, and shall be exercisable within thirty (30) days of JBC receiving written notice from Wells that an event permitting the exercise of the Put as described in clause (A) or (B) or (C) above
has occurred, by the giving of written notice of exercise to Wells. Notwithstanding the foregoing, if JBC gives notice on or prior to May 31, 2004 that it is exercising the Put, then the purchase price for JBC’s Partnership Interest shall be a
pro rata amount per percentage of the JBC Partnership Interest based upon the price Wells paid to VV City for the GP Interest under the Purchase Agreement, as adjusted for adjustments made under or pursuant to the Purchase Agreement. 
  
 (ii) From and after the giving of notice of exercise of the
Put by JBC, this Agreement shall be deemed for all purposes a legally enforceable contract between Wells, on the one hand, and JBC, on the other, for the sale by JBC of its entire Partnership Interest, and the purchase by Wells of such Partnership
Interest, subject to and on the terms set forth herein. 
  
 (iii) The “Fair Market Value” of the JBC Partnership Interest shall be determined for purposes of the Put in the same manner as the redemption price for the JBC Partnership Interest would be determined in a
redemption under Section 18(g) below. 
  
 (iv)
The “Closing” of the transfer pursuant to the Put shall be held at the office where the principal place of business of the Partnership, at 10:00 a.m. on the 60th day after the election by Wells (or, if such 60th day is not a Business Day,
on the next succeeding Business Day), time being of the essence of this Put; provided if the Fair 

  

 19 

 
Market Value has not been determined by such 60th day, the Closing shall occur on the 10th Business Day after such determination is made. On the Business Day
immediately prior to Closing, there shall be a preliminary closing at which JBC and Wells shall act diligently and in good faith to agree upon the form and substance of all documents necessary to effectuate the Closing. 
  
 (v) At the Closing, JBC shall deliver an assignment and, if
requested by Wells, a bill of sale (both with covenants against grantor’s acts, covenants of further assurances, and covenants or representations as to authorization, execution and delivery, and binding effect, but with no other covenants
unless mutually agreed) from the seller to the purchaser together with such other instruments and documents as may be reasonably necessary to effectuate the sale and transfer to the purchaser, legally sufficient to convey all of the Partnership
Interest of JBC to the purchaser, free and clear of all liens, claims, security interests and encumbrances created by JBC or any Affiliate thereof. The purchase price shall be paid at the Closing to JBC, by cash or federal wire transfer of
immediately available funds to an account designated by JBC. In the event there are any conveyance, transfer or similar taxes payable as an incident to the conveyances at the Closing, such taxes shall be expenses of JBC. 
  
 (vi) Wells shall have the right, in its sole and absolute
discretion, to cause its nominee(s) or designee(s) to acquire the JBC Partnership Interest at the Closing but nothing herein shall relieve Wells of its obligations under this Section 18(c). 
  
 (d) Limitations on Assignment. No Partner may Sell any Partnership
Interest (or any portion thereof or interest therein) to any Person, including without limitation any Sale pursuant to Section 18(b), and no Person shall become a Partner, unless in the opinion of counsel selected by or acceptable to the General
Partner, such action will not: (i) subject the Partnership to federal income taxation as an association taxable as a corporation (including, without limitation, causing the Partnership to be classified as a “publicly traded partnership”
under Section 7704 of the Code); (ii) or, violate applicable state or federal securities laws (such requirements, the “Assignment Conditions”). 
  
 (e) New Partners. A Person, including without limitation, an assignee of a Partnership Interest, shall be admitted as a Partner only upon the
written consent of the General Partner, which consent may be granted or withheld in the sole and absolute discretion of the General Partner. In the case of an assignment, unless and until the assignee of a Partnership Interest is admitted as a
Partner, the assignor, subject to the last sentence of Section 18(a), shall continue to be a Partner, and the assignee shall be a mere assignee under the Act. 
  

(f) Redemption. If requested by a Partner, the Partnership may redeem, but is not obligated to redeem, the Partnership Interest of any such
Partner upon the approval of the General Partner. 
  
 (g)
Restrictions on Transfer or Redemption. If a Limited Partner desires to Sell its Partnership Interest to any party, other than an Affiliate of such Partner, it shall provide written notice thereof to the Partnership, and the Partnership shall
have the right to cause such Partner’s Partnership Interest to be redeemed for an amount equal to the amount that such Partner would 

  

 20 

 
receive if the 35 W. Wacker Property, and any all other assets, if any, owned by the 35 W. Wacker Venture, were sold for their fair market value less all
liabilities of 35 W. Wacker Venture and the Partnership, as reasonably agreed upon by such Partner and the General Partner (and including without limitation the payment of all indemnification amounts that would then be owed to Leo Burnett USA, Inc.)
and both 35 W. Wacker Venture and the Partnership dissolved and distributed all of their respective assets after payment (or provision for payment) of all their respective liabilities. The Partnership shall have thirty (30) days following receipt of
such notice from a Limited Partner to (i) indicate whether or not it desires to redeem such Limited Partner’s Partnership Interest and (ii) if it elects to redeem such Limited Partner’s Partnership Interest, the proposed fair market value
of the foregoing described property, the foregoing liabilities and calculation of the amount payable to such Partner for purposes of such redemption. If the Limited Partner objects to such fair market value, it shall notify the General Partner
thereof in writing specifying in reasonable detail the nature of its objection and the parties shall in good faith attempt to resolve such disagreement. If the parties are unable to resolve such disagreement within thirty (30) days after notice, the
matter shall be settled by arbitration pursuant to Section 19. If the Partnership elects not to redeem the Partnership Interest, then such Limited Partner shall be permitted to sell and assign its Partnership Interest during the twelve (12) month
period thereafter. 
  
 SECTION 19. ARBITRATION PROCEDURE.

  
 If the Partners are unable to mutually agree upon the fair
market value of the Partnership Interest within the thirty (30) day periods of Section 18(c)(iii) or Section 18(g), as applicable, such value shall be settled at the request of any Partner by arbitration in Chicago, Illinois in accordance with the
Commercial Arbitration Rules of the American Arbitration Association. The arbitration shall be conducted by a single arbitrator who shall be mutually selected by JBC and Wells (in the case of a proceeding pursuant to Section 18(c)(iii) or by the

Each of the Partners participating in the proceeding shall be required as part of the arbitration of fair market value of the Partnership Interest to present its proposed fair market value of the Partnership Interest to the arbitrator. The
arbitrator, in making his decision, shall be required to select that proposal which is the closest to the arbitrator’s view of fair market value of the Partnership Interest. If the parties are unable to agree upon an arbitrator within 30 days
of notice by either party to the other, then at the written request of either the Selling Partner or the General Partner, each shall select one arbitrator meeting the above qualifications within 30 days of receipt of such request, and the two
arbitrators so selected shall appoint the arbitrator meeting the above qualifications to make the determination under this Section. In the event a Partner fails to appoint its arbitrator in accordance with the preceding sentence, the arbitrator
appointed by the other Partner shall be the arbitrator for purposes of settling the dispute which is the subject of such arbitration. The determination by the arbitrator shall be final and binding on the Partners and may be entered in any court
having jurisdiction thereof. The fees and expenses of the arbitrator and all other expenses of the arbitration shall be paid one-half by the General Partner and one-half by the Partner whose interest is to be sold.

class of Limited Partner, (II) modify the limited liability of a Limited Partner interest, (III) alter rights of the Limited Partner to receive distributions

 (l) Facsimile Signatures. The facsimile signature of any Partner may
be used at all times and for all purposes in place of an original signature. 
  
 (m) Reliance upon Books, Reports and Records. Unless he has knowledge concerning the matter in question which makes his reliance unwarranted, each General Partner and Partner shall, in the performance of his
duties hereunder, be entitled to rely on information, opinions, reports or statements, including, without limitation, financial statements and other financial data, if prepared or presented by one or more employees of the Partnership or by legal
counsel, accountants or other Persons as to matters such General Partner or Partner reasonably believes to be within such Person’s professional or expert competence.

upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute waiver of any such breach or any other covenant, duty, agreement or
