such information in confidence shall be satisfied if they exercise the same care with respect to such information as they would take to preserve the confidentiality of their own similar information but with no less than a reasonable standard of
care. If this Agreement is terminated, upon the written request of Purchaser, the Seller Parties and their Affiliates will, and will cause their respective employees, directors, managers, accountants, counsel, consultants, advisers and agents to,
destroy or deliver to Purchaser all documents and other materials, and all copies thereof, obtained by any of the Seller Parties or their Affiliates or on their behalf from Purchaser or its Affiliates in connection with this Agreement that are

release or public announcement in respect of this Agreement or the transactions contemplated by this Agreement is made by the NYSE prior to the Closing (the NYSE Release), the parties may issue or cause the publication of a press

EMPLOYEE BENEFITS MATTERS

Section 10.1. Employment. Purchaser shall make offers of employment to the Employees designated by Purchaser on a schedule to
be provided prior to the Closing to Seller and Seller Parent by Purchaser, subject to each such Employees satisfaction of Purchasers standard policy requirements and conditions applicable to new hires. All Employees who accept such
offers of employment and become employed by Purchaser as of the Closing Date shall be referred to as Acquired Employees. The parties acknowledge and agree that no contracts of employment with Seller shall be assumed by Purchaser
as a result of the transactions contemplated by this Agreement or the hiring of the Acquired Employees hereunder. From and after the date hereof, neither Seller nor Seller Parent shall engage in any activity intended to discourage any Employee from
accepting an offer of employment from Purchaser. Upon the execution of this Agreement by the parties, the Seller Parties shall provide Purchaser access to any personnel files pertaining to the Employees to facilitate Purchasers determination
of which Employees to whom offers of employment shall be made pursuant to this Section 7.5(a); provided that such personnel files shall be provided in such a manner as to maintain confidentiality of the information contained therein.

Section 10.2. Post-Closing Benefits.

(a) Except as otherwise provided in this Agreement, for the twelve (12) month period following the Closing Date, Purchaser shall
provide the Acquired Employees with salary, wages and employee benefits that are no less favorable in the aggregate than those provided to similarly situated employees of Purchaser while such Acquired Employees remain employed by Purchaser. For the
avoidance of doubt, nothing in this provision shall entitle any Acquired Employee to any particular bonus or other incentive payment or compensation level. Seller Parent acknowledges and agrees that any Employee that receives an offer that is
consistent with this Section 10.2(a) shall not be eligible for or receive severance from Purchaser or any of its Affiliates under any severance plan, policy, arrangement or agreement of Seller, Seller Parent, Purchaser or such Affiliates.

(b) Purchaser shall credit the Acquired Employees for their service with Seller and its Affiliates to the same extent
recognized by Seller or its Affiliates immediately prior to the Closing Date for all purposes under the employee benefit plans or arrangements maintained by Purchaser or any of its Affiliates (including any welfare plan, pension plan, vacation
program or severance program) in which any such Acquired Employees participate post-Closing, except: (1) for purposes of benefit accrual under any defined benefit retirement plan(s) maintained by Purchaser or its Affiliates; (2) for
purposes of vesting under any tax qualified or excess or supplemental plan maintained by Purchaser or its Affiliates; and (3) to the extent such credit would result in an unintended duplication of benefits.

incurred and benefits earned after the Closing Date under and subject to the generally applicable terms and conditions of Purchasers employee benefit plans, programs and arrangements as in effect from time to time. For purposes of this
Section 10.3, a claim shall be deemed to be incurred on the date that the event that gives rise to such claim occurs, except that any claim that relates to a continuous period of hospitalization shall be deemed to be incurred at the
commencement of such period of hospitalization. Without limiting the generality of the foregoing, and for purposes of clarification, a claim for disability benefits shall be deemed to be incurred at the time that the event that gives rise to the
disability occurs, and the responsibility for all future disability benefits payable with respect to such disability shall be determined based on the date on which such event occurs.

Section 10.4. Bonus. Seller shall be responsible for, pay and retain all liability related to, all bonuses and incentive
compensation due to Employees (including all Acquired Employees), in respect of the 2009 fiscal year, including any taxes payable by Seller thereon. Purchaser shall be responsible for all bonuses and incentive compensation, if any, for Acquired
Employees for the 2010 fiscal year and thereafter, including any taxes payable by Purchaser thereon.

Section 10.6. COBRA. Seller Parent shall be responsible for all legally mandated continuation of health care coverage for all
Acquired Employees and any of their covered dependents who experience qualifying event occurring on or prior to the Closing Date. Purchaser shall be responsible for all legally mandated continuation of health care coverage for all Acquired Employees

Date, all Acquired Employees shall be eligible to participate in any Section 401(k) plan maintained by Purchaser and Purchaser shall take any and all necesssary action to cause the trustee of such plan to accept direct rollover contributions
(within the meaning of Section 401(a)(31) of the Code) in respect of any Acquired Employee, subject to receipt by the plan recordkeeper of any applicable records



46



---

or documentation regarding the LaBranche & Co. Inc. Retirement Plan (nonstandardized 401(k) plan), reasonable requested bysuch plan recordkeeper. For the avoidance of doubt,

requirements or obligations imposed by the Worker Adjustment and Retraining Notification Act (WARN Act), or any similar statute, with respect to any event affecting Acquired Employees occurring after the Closing Date.

Purchaser or any of its Affiliates to terminate the employment of any Acquired Employee at any time from and after the Closing.

TAX MATTERS

Section 11.1. Tax Indemnification. Seller and Seller Parent shall be responsible for and shall pay, and shall jointly and
severally indemnify and save Purchaser harmless from, any and all Taxes levied or imposed on Seller in respect of the Transferred Assets (A) that are allocated to Seller pursuant to this Article XI or (B) which arise from or relate
to the breach or inaccuracy of any representation or warranty contained in Section 5.17 (Taxes). Purchaser shall be responsible for and shall pay, and shall indemnify and save Seller and Seller Parent harmless from, any and all Taxes
that are allocated to Purchaser pursuant to this Article XI.

Section 11.2. Liability for Taxes. Notwithstanding
anything in this Agreement to the contrary, Seller shall be liable for and shall pay, all Taxes (whether assessed or unassessed) (i) applicable to the Transferred Assets or the Acquired Business, to the extent attributable to taxable years or
periods (or portions thereof) ending on or prior to the Closing Date or (ii) imposed on Seller, or for which Seller may otherwise be liable, attributable to any taxable years or periods (including, without limitation, any Taxes resulting from

or unassessed) attributable to the Transferred Assets or the Acquired Business, to the extent attributable to taxable years or periods (or portions thereof) beginning after the Closing Date.

Section 11.3. Tax Returns and Tax Payments. Seller shall be responsible for the timely filing (taking into account any
extensions received from the relevant tax



47



---

authorities) of all Tax Returns required by law to be filed in respect of the Transferred Assets (or the Acquired Business) on or prior to the Closing Date. All Taxes indicated as due and payable
on such returns shall be paid or will be paid by Seller as and when required by law, and Purchaser shall reimburse Seller for any portion of such Taxes for which Purchaser is responsible under this Article XI. Purchaser shall be responsible for the
timely filing (taking into account any extensions received from the relevant tax authorities) of all Tax Returns required by law to be filed in respect of the Transferred Assets or the Acquired Business after the Closing Date.

Section 11.4. Apportionment of Taxes. The parties hereto agree that all personal property Taxes and similar ad
valoremobligations that are levied with respect to the Transferred Assets or the Acquired Business for assessment periods within which the Closing Date occurs (collectively, the Apportioned Obligations) shall be
apportioned between Seller and Purchaser as of the Closing Date based on the number of days in any such period falling on or before the Closing Date, on the one hand, and after the Closing Date, on the other hand (it being understood that Purchaser
is responsible for the portion of each such Apportioned Obligation attributable to the number of days after the Closing Date in the relevant assessment period). Purchaser shall cooperate in assuring that Apportioned Obligations the payment of which
is due on or prior to the Closing Date are billed directly to and paid by Seller, and that Apportioned Obligations whose payment is due after the Closing Date shall be billed directly to and paid by Purchaser. On the Closing Date, Seller shall
deliver to Purchaser any bill received by it in respect of any Apportioned Obligations not yet due and payable together with payment in an amount equal to Sellers pro rata share of such bill. Seller and Purchaser shall each
present or cause to be presented a statement to the other setting forth the amount of reimbursement to which each is entitled under this Article XI as of the most recent practicable date (together with such supporting evidence as may be
reasonably requested), and they shall calculate the amount by which such reimbursement owed to one party exceeds that owed to the other (the Proration Amount), and on such date the Proration Amount so determined shall be paid by
the party owing it to the other. Thereafter, Seller shall notify Purchaser upon receipt of any bill for Apportioned Obligations, part or all of which are attributable to any period following the Closing Date, and shall promptly deliver such bill to
Purchaser who shall pay the same to the appropriate taxing authority or other obligee, provided that if such bill covers any Apportioned Obligations for any period on or before the Closing Date, Seller shall also remit to Purchaser, prior to
the due date of such bill, payment of the proportionate amount of such bill that is attributable to such period on or before the Closing Date. In the event that any party shall thereafter make a payment for which it is entitled to reimbursement
under this Article XI, the party so obligated to make such reimbursement under this Article XIshall make such reimbursement promptly upon the presentation of such supporting evidence as may be reasonably requested. The parties hereto
shall cooperate, including, without limitation, during times of audit by taxing authorities, to avoid payment of duplicate or inappropriate Taxes or other ad valorem obligations of any kind or description which relate to the
Transferred Assets or the Acquired Business, and each of Purchaser and Purchaser shall furnish, at the request of the other, proof of payment of any such Taxes or ad valoremobligations or other documentation that is a prerequisite to
avoiding payment of a duplicate or inappropriate tax or other ad valoremobligations. In the event that it is determined subsequent to the



48



---

Closing Date that additional personal property Taxes or similar ad valorem obligations which are Apportioned Obligations are required to be paid for the assessment period in which
the Closing Date falls, the parties hereto agree that such additional Taxes will be apportioned between Seller and Purchaser on the basis of each respective ownership of the taxed asset during the assessment period.

Section 11.5. Transfer Tax. Seller shall pay directly, or reimburse Purchaser promptly upon demand and delivery of proof of
payment for, all excise, sales, transfer, real estate transfer, documentary, filing, recordation, conveyance, recording and other similar taxes, levies, fees and charges (collectively, Transfer Taxes), that may be imposed upon, or
be payable or collectible or incurred in connection with, this Agreement and the transactions contemplated hereby. Seller shall be responsible for preparing and timely filing any Tax Returns required with respect to any such Transfer Taxes.

its own income and franchise Taxes, if any, arising from the transactions contemplated by this Agreement.

Section 11.7.
Survival. All obligations under this Article XI and the representations and warranties contained in Section 5.17 (Taxes) shall survive the Closing hereunder and continue until sixty (60) days following the expiration
of the statute of limitations on assessment of the relevant Tax. Notwithstanding the foregoing, any claim for indemnification shall survive such termination date if any party, on or prior to such termination date, shall have advised the other party
in writing of facts that constitute or may give rise to a claim for indemnification under this Article XI, specifying in reasonable detail the basis under this Agreement for such claim.

Section 11.8. Tax Effect of Indemnification Payments. All indemnification payments made pursuant to Article XI and Article
XII below shall be treated for all Tax purposes as adjustments to the Purchase Price.

Section 11.9. Exclusivity.
The indemnification provided for in this Article XI shall be the sole remedy for any claim in respect of Taxes, including any claim arising out of or relating to a breach or inaccuracy of any representation or warranty contained in
Section 5.17 (Taxes). In the event of a conflict between the provisions of this Article XI, on the one hand, and the provisions of Article XII, on the other, the provisions of this Article XI shall control. Without
limiting the generality of the foregoing, neither the Sub-Basket nor the Basket shall apply to any claim in respect of Taxes.

ARTICLE XII

INDEMNIFICATION

Section 12.1. Indemnification by Seller Parties. From and after the Closing, but subject to the conditions and limitations
set forth in this Agreement, Seller and Seller Parent shall jointly and severally indemnify and hold Purchaser, its Affiliates and their respective directors, managers, officers, employees and agents (collectively, the Purchaser Indemnified
Persons) harmless from and against any and all Losses incurred or required to be paid by any Purchaser Indemnified Person to the extent arising out of, relating to or caused by (i) the breach of any representation or warranty of a
Seller Party contained in this Agreement; (ii) the breach of any covenant or agreement of a Seller Party contained in this Agreement; (iii) the Excluded Liabilities (including, without limitation, any Pre-Acquisition Action Liabilities or
Permitted Liens); or (iv) the ownership of the Transferred Assets or the operation by Seller of the Business as of or prior to the Closing; provided that the Seller and Seller Parent shall have no obligation to indemnify or hold harmless
any Purchaser Indemnified Person from and against (A) any individual Loss or series of related Losses (arising from the same event or circumstance) pursuant to Section 12.1(i) (other than with respect to breaches of any of the
Fundamental Representations) that is less than twenty thousand dollars ($20,000.00) (calculated in the aggregate for a series of related Losses) (the Sub-Basket) and (B) any individual Loss or series of related Losses
(arising from the same event or circumstance) pursuant to Section 12.1(i) (other than with respect to breaches of any of the Fundamental Representations) where the Loss relating thereto is equal to or greater than the Sub-Basket, unless
the aggregate amount of all such Losses exceeds $350,000.00 (the Basket). In no event shall the aggregate indemnification paid by Seller and Seller Parent pursuant to Section 12.1(i) and Section 12.1(ii)
(other than with respect to a breach of any covenant to indemnify for amounts in excess of the Cap under this Section 12.1) exceed the Purchase Price (the Cap).

Section 12.2. Indemnification by Purchaser. From and after the Closing, but subject to the conditions and limitations set
forth in this Agreement, Purchaser shall indemnify and hold Seller, its Affiliates and their respective directors, managers, officers, employees and agents (collectively, the Seller Indemnified Persons) harmless from and against
any and all Losses incurred or required to be paid by any Seller Indemnified Person to the extent arising out of, relating to or caused by (i) the breach of any representation or warranty of Purchaser contained in this Agreement, (ii) the
breach of any covenant or agreement of Purchaser contained in this Agreement, (iii) any Assumed Liability and (iv) the ownership of the Transferred Assets from and after the Closing Date or the operation of Purchasers business with
respect thereto after the Closing Date; provided that Purchaser shall have no obligation to indemnify or hold harmless any Seller Indemnified Persons from and against (a) any individual Loss or series of related Losses pursuant to
Section 12.2(i) (other than with respect to breaches of representations and warranties set forth in Sections 6.1, 6.2 and 6.6) (arising from the same event or circumstance) that is less than the Sub-Basket and
(b) any individual Loss or series of related Losses pursuant to Section 12.2(i) (other than with respect to breaches of representations and warranties set forth in Sections 6.1, 6.2 and 6.6) (arising from the



50



---

same event or circumstance) where the Loss relating thereto is equal to or greater than the Sub-Basket, unless the aggregate amount of all such Losses exceeds the Basket. In no event shall the
aggregate indemnification paid by Purchaser pursuant to Section 12.2(i) and Section 12.2(ii) (other than with respect to a breach of any covenant to indemnify for amounts in excess of the Cap under this
Section 12.2) exceed the Cap.

Section 12.3. Procedures.

(a) A party claiming indemnification hereunder (an Indemnified Party) shall promptly give the party from whom
indemnification is sought (an Indemnifying Party) written notice of any matter which an Indemnified Party has determined has given or could give rise to a right of indemnification under this Agreement, stating in reasonable detail
to the extent known, (i) the basis for any such claim for indemnification, (ii) the amount of the Loss and the method of computation thereof, (iii) and containing a reference to the provisions of this Agreement in respect of which
such right of indemnification is claimed or arises; provided that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article XII except to the extent that such failure
actually materially prejudices the Indemnifying Party.

(b) If an Indemnified Party shall receive notice of any claim of a
third party that would give rise to a right of indemnification hereunder (a Third Party Claim), then the Indemnified Party shall give the Indemnifying Party written notice of such Third Party Claim (stating in reasonable detail
the basis for claiming such right of indemnification); provided that the failure to provide such notice shall not release the Indemnifying Party from any of its obligations under this Article XII except to the extent that such failure
actually materially prejudices the Indemnifying Party. In the event of a Third Party Claim, the Indemnifying Party may elect to assume the defense of such Third Party Claim and elect to retain counsel of its choice, reasonably acceptable to the
relevant Indemnified Parties, to represent such Indemnified Parties in connection with such Proceeding and shall pay the fees, charges and disbursements of such counsel and other defense costs. The Indemnified Parties may participate, at their own
expense and through legal counsel of their choice, in any such Proceeding; provided that (i) the Indemnifying Party shall have the right to defend such Third Party Claim by all appropriate proceedings and, so long as it diligently
pursues such defense, shall have full control of such defense and such proceedings, and (ii) the Indemnified Parties and their counsel shall cooperate with the Indemnifying Party and its counsel in connection with such Proceeding. The
Indemnifying Party shall not settle any such Proceeding without the relevant Indemnified Parties prior written consent (which shall not be unreasonably withheld or delayed), unless the terms of such settlement contain a complete and
unconditional release of the Indemnified Party of any Liability.

(c) Notwithstanding the foregoing, if (i) the
Indemnifying Party elects not to assume control of such defense, (ii) both the Indemnifying Party and any Indemnified Party are parties to or subjects of such claim and conflicts of interests exist between the Indemnifying Party and such
Indemnified Party, or (iii) the claim is reasonably likely to establish a precedential custom or practice that is detrimental to the



51



---

continuing business interests of the Indemnified Party, then the Indemnified Parties may retain counsel reasonably acceptable to the Indemnifying Party in connection with such claim and assume
control of the defense in connection with such claim, and the fees, charges and disbursements of no more than one such counsel per jurisdiction selected by the Indemnified Parties shall be reimbursed by the Indemnifying Party. Under no circumstances
will the Indemnifying Party have any Liability in connection with any settlement of any Proceeding that is entered into without its prior written consent (which shall not be unreasonably withheld or delayed). Notwithstanding any other provisions of
this Article XII and regardless of whether it is an Indemnified Party or Indemnifying Party, Purchaser shall have the right to assume the full control of defense against any claim giving rise to a right of indemnification under this Agreement
that relates to any Losses relating to or arising from the period subsequent to the date hereof (a Post-Signing Claim) and may elect to retain counsel of its choice reasonably acceptable to the Seller Parties, so long as Purchaser
diligently pursues such defense. The fees, charges and disbursements of no more than one such counsel per jurisdiction selected by Purchaser with respect to any such Post-Signing Claim shall be reimbursed by the Indemnifying Party.

(d) If there is a litigation or proceeding at any time that concerns the Acquired Business or Transferred Assets before the Closing Date
and a notice of claim in accordance with Section 12.3(a) or Section 12.3(b), as the case may be, is not submitted with respect to such litigation or proceeding, then, at the reasonable request of Purchaser, the Seller Parties
shall make the employees of the Seller Parties and their Subsidiaries available to cooperate with Purchaser and its Affiliates (including by making such employees available to provide information, discovery and testimony), to the extent reasonable
and without interrupting the business or operations of the party receiving such request and of its Subsidiaries, in each case solely for purposes of permitting the preparation for, defense of and participation in such litigation or proceeding by any
of the requesting party, its Affiliates or their respective agents, directors, officers and employees; provided that the requesting party shall reimburse all reasonable out-of-pocket expenses incurred by the party receiving such request, its
Affiliates and their respective agents, directors, officers and employees in complying with this undertaking and, since such payments, if any, will not be made pursuant to an indemnity claim, such payments shall not be taken into account for
purposes of the limitations set forth in Section 12.1 or Section 12.2.

(e) Survival of
Representations and Warranties. Except as otherwise provided in this Agreement, the representations and warranties of the Seller Parties and Purchaser contained in this Agreement (and the rights to indemnification in respect thereof) shall
terminate on the date that is eighteen (18) months following the Closing Date; provided that (x) the Fundamental Representations shall survive indefinitely; and (y) if a claim for indemnification hereunder arises, and the
Indemnified Party notifies in writing the Indemnifying Party with respect thereto, on or prior to the expiration of such period, the Indemnified Partys right to indemnification hereunder shall continue until the claim is finally resolved and
any related Losses are paid.

Section 12.4. Exclusive Remedy. The provisions of this Article XII are
intended to be the exclusive monetary remedy between the parties following the Closing for the matters covered by this Agreement (including any Liabilities arising prior to the Closing, but excluding any claim in respect of Taxes, which shall be
governed exclusively by Article XI), and no party shall seek recovery from the other party with respect to such matters under theories of strict liability, negligence or other theory of recovery, whether under contract or tort or at Law or in
equity.

Section 12.5. Limitations.

(a) Notwithstanding anything to the contrary contained herein, none of the parties shall have any Liability under any provision of this
Agreement for any punitive, incidental, consequential, special or indirect damages, or loss of value except to the extent that (i) any such damages are awarded to a third party in connection with a Third Party Claim against an Indemnified Party
and (ii) such Indemnified Party is entitled to be indemnified hereunder as a result of the facts or circumstances giving rise to such Third Party Claim.

(b) The amount of any Losses for which indemnification is provided under this Article XII shall be net of any amounts actually
recovered through insurance or otherwise with respect to such Losses (net of any Tax or expenses incurred in connection with such recovery).

Section 12.6. Mitigation. Each of the parties hereto agrees to take all commercially reasonable steps to mitigate their
respective Losses upon and after becoming aware of any event or condition that would, individually or in the aggregate, reasonably be expected to give rise to any Losses that are indemnifiable hereunder.

ARTICLE XIII

GENERAL PROVISIONS

Section 13.1. Notices. All notices, requests, claims, demands and other communications hereunder shall be in writing and

facsimile delivery) to the respective parties at the following addresses (or at such other address for a party as shall be specified by like notice):

Copies to be sent as indicated above shall be courtesy copies and failure to deliver any such courtesy
copies shall not invalidate any notice properly delivered to Purchaser, Seller or Seller as set forth above.

Section 13.2. Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being
enforced by any rule of law or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected
in any manner materially adverse to any of the parties. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties shall negotiate in good faith to modify this Agreement so as to effect
the original intent of the parties as closely as possible in an acceptable manner to the end that the transactions contemplated hereby are fulfilled to the fullest extent possible.

Section 13.3. Entire Agreement; Assignment; Execution. This Agreement, together with the Confidentiality Agreement and the
Related Documents, constitutes the entire agreement among the parties with respect to the subject matter hereof and supersedes all prior agreements and undertakings, both written and oral, among the parties, or any of them, with respect to the
subject matter hereof. This Agreement shall not be assigned and no obligations hereunder may be transferred by any party, provided, however, that Purchaser may transfer any of its rights and obligations to any Affiliate of Purchaser,
but no such assignment shall relieve Purchaser of its obligations hereunder. Any attempted assignment or transfer which does not comply with the provisions of this Section 13.3 shall be null and void ab initio. This Agreement
shall be binding upon a party hereto only upon the manual execution and delivery (which delivery may be by telecopy or facsimile or electronic mail) of a signature page to a counterpart hereto.

Section 13.4. Parties in Interest. This Agreement shall be binding upon and inure to the benefit of each party, its
successors in interest and permitted assigns, and nothing in this Agreement, express or implied, is intended to or shall confer upon any other Person, other than the Indemnified Parties who shall have rights to the extent provided under Article
XII, any rights, benefits or remedies of any nature whatsoever under or by reason of this Agreement.

Section 13.5.
Amendment. This Agreement may not be amended or modified except by an instrument in writing signed by Seller and Purchaser.

Section 13.6. Waiver. At any time prior to the Closing Date, any party hereto
may (a) extend the time for the performance of any of the obligations or other acts of the other parties, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant hereto, and
(c) waive compliance with any of the agreements or conditions contained herein. Any such extension or waiver shall be valid only if set forth in an instrument in writing signed by the Persons to be bound thereby. The failure or delay of any
party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

Section 13.7. Governing Law; Jurisdiction.

(a) This Agreement and any dispute arising out of, in connection with or relating to this Agreement shall be governed by, and construed in
accordance with, the laws of the State of New York applicable to agreements made and to be performed entirely within that state.

(b) Each of the parties irrevocably and unconditionally submits to the exclusive jurisdiction of the United States District Court for the
Southern District of New York located in the borough of Manhattan in the City of New York, or if such court does not have jurisdiction, the Supreme Court of the State of New York, New York County, for the purposes of any suit, action or other
proceeding arising out of this Agreement or any transaction contemplated hereby. Each of the parties further agrees that service of any process, summons, notice or document by U.S. registered mail to such Partys respective address set forth in
Section 13.1 shall be effective service of process for any action, suit or proceeding in New York with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each of the
parties irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of this Agreement or any transaction contemplated hereby or thereby in (a) the United States District Court for
the Southern District of New York or (b) the Supreme Court of the State of New York, New York County, and hereby further irrevocably and unconditionally (i) waives, and agrees not to assert, by way of motion, as a defense, counterclaim or
otherwise, in any such litigation or proceeding, any claim that it is not personally subject to the jurisdiction of the aforesaid courts for any reason other than the failure to serve process in accordance with this Section 13.7, that it or its
property is exempt or immune from jurisdiction of any such court or from any legal process commenced in such courts (whether through service of notice, attachment prior to judgment, attachment in aid of execution of judgment, execution of judgment
or otherwise), and to the fullest extent permitted by law, that the litigation in any such court is brought in an inconvenient forum and (ii) agrees not to commence any action, claim, cause of action or suit, in contract, tort or otherwise
arising out of this Agreement and the transactions contemplated hereby and thereby other than in (A) the United States District Court for the Southern District of New York or (B) the Supreme Court of the State of New York, New York County.
The parties intend that any judgment of either such court shall be enforceable in all other jurisdictions.

(c) Each of the
parties irrevocably and unconditionally waives, to the fullest extent permitted by applicable Law, any and all rights to trial by jury in connection with any litigation or proceeding arising out of this Agreement or the transactions contemplated
hereby.

Section 13.8. Specific Performance. Each party to this Agreement shall be
entitled to compel specific performance of this Agreement and to seek other applicable equitable relief in the event of any breach or threatened breach of this Agreement by another Party and the parties hereby waive for such purposes the defense of
adequate remedy at law.

Section 13.9. Captions. The captions, headings and arrangements used in this Agreement
are for convenience only and do not in any way affect, limit or amplify the terms and provisions hereof. References in this Agreement to Articles or Sections shall mean Articles or Sections of this Agreement unless specifically otherwise provided.
Any of the terms defined in this Agreement may be used in the singular or plural, as applicable.

Section 13.10.
Counterparts. This Agreement may be executed in two or more counterparts, and by the different parties in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute
one and the same agreement.

Section 13.11. Expenses. Except as otherwise expressly provided in this Agreement,
each party shall bear and pay its own costs and expenses (other than Taxes) incurred in connection with the transactions contemplated by this Agreement.
