Company under this Agreement shall be increased as necessary so that after making all payments in respect to Taxes imposed on or attributable to such indemnity payment, the recipient Company receives an amount equal to the sum it would have received
had no such Taxes been imposed. 
 (b) Interest Under This Agreement. Anything herein to the contrary notwithstanding, to the extent
one Company (“Indemnitor”) makes a payment of interest to another Company (“Indemnitee”) under this Agreement with respect to the period from the date that the Indemnitee made a payment of Tax to a Tax Authority to
the date that the Indemnitor reimbursed the Indemnitee for such Tax payment, the interest payment shall be treated as interest expense to the Indemnitor (deductible to the extent provided by law) and as interest income by the Indemnitee (includible
in income to the extent provided by law). The amount of the payment shall not be adjusted to take into account any associated Tax Benefit to the Indemnitor or increase in Tax to the Indemnitee. 

Section 4. Tax Refunds 

Section 4.01 Tax Refunds. SunEdison shall be entitled to any refund (and any interest thereon received from the applicable Tax
Authority) attributable to SunEdison Taxes, and Semiconductor shall be entitled to any refund (and any interest thereon received from the applicable Tax Authority) attributable to Semiconductor Taxes. A Company receiving a refund to which the other
Company is entitled hereunder shall pay over such refund to such other Company (without the requirement that such other Company demand or request such refund) within twenty (20) Business Days after such refund is received (together with
interest in accordance with Section 13, computed based on the number of days from the date the refund was received to the date the refund was paid over). To the extent the amount of any refund under this Section 4.01 is later reduced by a
Tax Authority, such reduction shall be allocated to the Company to which such refund was allocated pursuant to this Section 4.01 and an appropriate adjusting payment shall be made. 

Section 5. Gain Recognition Agreements. 

Section 5.01 Gain Recognition Agreements. Semiconductor shall not (i) take any action (including, but not limited to, the
sale or disposition of any stock, securities, or other assets), (ii) permit any member of the Semiconductor Group to take any such action, (iii) fail to take any action, or (iv) permit any member of the Semiconductor Group to fail to
take any action, in each case that would cause any member of the SunEdison Group to recognize gain under any Gain Recognition Agreement, provided, in each case, that the restrictions set forth in clauses
(i)-(iv)

  
 13 








 
shall not apply to any actions or any failures to take any actions that are specifically allowed or prohibited under the Separation Agreement or any Ancillary Agreement. In addition,
Semiconductor shall file, and shall cause any member of the Semiconductor Group to file, any Gain Recognition Agreement reasonably requested by SunEdison, which Gain Recognition Agreement is determined by SunEdison to be necessary so as to
(i) allow for or preserve the tax-free or tax-deferred nature, in whole or part, of any Separation Transaction, or (ii) avoid any member of the SunEdison Group recognizing gain under any Gain Recognition Agreement. 

Section 6. Tax Incentive, and Escheat and Other Liabilities. 

Section 6.01 Tax Incentive Arrangements. SunEdison shall be responsible for any liability to a government entity arising from
SunEdison’s failure to satisfy the terms and conditions imposed on SunEdison under any Tax Incentive Arrangement from and after the Distribution Date (any such liability, a “SunEdison Incentive Liability”). Semiconductor shall
be responsible for any liability to a governmental entity arising from Semiconductor’s failure to satisfy the terms and conditions imposed on Semiconductor under any Tax Incentive Arrangement from and after the Distribution Date (any such
liability, a “Semiconductor Incentive Liability”). If and to the extent both SunEdison and Semiconductor fail to satisfy their respective terms and conditions under a Tax Incentive Arrangement, each of SunEdison and Semiconductor
shall bear any resulting liability based on the extent to which its own failure contributed to, and caused, such liability. Any disputes concerning the interpretation and application of this Section 6.01 shall be resolved in accordance with
Section 12. 
 Section 6.02 Escheat Liability. SunEdison shall be responsible for any unclaimed property or escheat liability
(whether for a period before or after the Distribution Date), including any interest, penalty, administrative charge, or addition thereto and further including all costs of responding to or defending against an audit, examination, or controversy
with respect to such liability, imposed by or on behalf of a government entity with respect to any property or obligation (including, without limitation, uncashed checks to vendors, customers, or employees and
non-refunded overpayments) attributable to the SunEdison Business, without regard to whether the government entity imposes such liability on the SunEdison Group or the Semiconductor Group (any such liability,
a “SunEdison Escheat Liability”). Semiconductor and SunEdison shall each be responsible for 50% of any unclaimed property or escheat liability (whether for a period before or after the Distribution Date), including any interest,
penalty, administrative charges, or additions with respect thereto and further including all costs of responding to or defending against an audit, examination, or controversy with respect to such liability, imposed by or on behalf of a government
entity with respect to any property or obligation (including, without limitation, uncashed checks to vendors, customers, or employees and non-refunded overpayments) attributable to the Semiconductor Business,
without regard to whether the government entity imposes such liability on the Semiconductor Group or the SunEdison Group (any such liability, a “Semiconductor Escheat Liability”). SunEdison and Semiconductor shall jointly determine
in good faith which unclaimed property or escheat liabilities are properly attributable to the Semiconductor Business and which unclaimed property or escheat liabilities are properly attributable to the SunEdison Business (and in the case of an
unclaimed property or escheat liability that is properly attributable to both the SunEdison Business and the Semiconductor Business, the allocation of such liability between the SunEdison Business and the Semiconductor Business). For the avoidance
of doubt, any unclaimed property 

  
 14 








 
or escheat liability with respect to property or an obligation on the books of a member of the SunEdison Group at the time such liability is imposed shall be considered attributable to the
SunEdison Business and any unclaimed property or escheat liability with respect to property or an obligation on the books of a member of the Semiconductor Group shall be considered attributable to the Semiconductor Business. Any disputes concerning
the interpretation and application of this Section 6.02 shall be resolved in accordance with Section 12. 
 Section 6.03
MKC Tax Audit. Notwithstanding anything else herein, SunEdison shall reimburse the Semiconductor Group for any liability for Tax resulting from adjustments made by Korea’s National Tax Service to the income of MEMC Korea Company for the
Tax Periods ended December 31, 2008 through December 31, 2013, to the extent the competent Tax Authority in the United States agrees to make a correlative adjustment on SunEdison’s (United States Federal) Tax Return, provided such
reimbursement shall be limited to the amount of net Tax benefit actually realized by SunEdison as a result of such correlative adjustment. The foregoing reimbursement shall be due at such time or times, and solely to the extent, that a net Tax
benefit is actually realized (on a marginal, “with” versus “without” basis) through a refund of Tax or actual reduction in the amount of Tax that SunEdison otherwise would have paid if such correlative adjustment had not been
made. 
 Section 7. Assistance and Cooperation. 

Section 7.01 Assistance and Cooperation. 

(a) General Cooperation. The Companies shall each cooperate fully (and each shall cause its respective Affiliates to cooperate fully)
with all reasonable requests in writing or via e-mail from the other Company, or from an agent, representative or advisor to such Company, in connection with the preparation and filing of Tax Returns, claims for refunds, Tax Contests, and
calculations of amounts required to be paid pursuant to this Agreement, in each case, related or attributable to or arising in connection with Taxes of either of the Companies or their respective Affiliates covered by this Agreement and the
establishment of any reserve required in connection with any financial reporting (a “Tax Matter”). Such cooperation shall include the provision of any information reasonably necessary or helpful in connection with a Tax Matter and
shall include, without limitation: 
 (1) the provision, in hard copy and electronic forms, of any Tax Returns of the
Companies and their respective Affiliates, books, records (including information regarding ownership and Tax basis of property), documentation and other information relating to such Tax Returns, including accompanying schedules, related work papers,
and documents relating to rulings or other determinations by Tax Authorities; 
 (2) the execution of any document (including
any power of attorney) reasonably requested in connection with any Tax Contest of either of the Companies or their respective Affiliates, or the filing of a Tax Return or a refund claim of either of the Companies or any of their respective
Affiliates; 
 (3) making available to each other for inspection and copying during normal business hours upon reasonable
notice all Tax Records (and, for the avoidance of doubt, 

  
 15 








 
any pertinent underlying data accessed or stored on any computer program or information technology system) in its possession, and permitting the other Company and its Affiliates, authorized
agents and representatives and any representative of a Taxing Authority or other Tax auditor direct access, during normal business hours upon reasonable notice, to any computer program or information technology system used to access or store any Tax
Records, in each case to the extent reasonably required by the other Company in connection with the preparation of Tax Returns or financial accounting statements, audits, litigation, or the resolution of items under this Agreement; and 

(4) the use of the Company’s reasonable best efforts to obtain any documentation in connection with a Tax Matter. 

Each Company shall make its employees, advisors, and facilities available, without charge, on a reasonable and mutually convenient basis in connection with
the foregoing matters in a manner that does not interfere with the ordinary business operations of such Company. Each Company shall bear its own costs and expenses associated with fulfilling its obligations under this Section 7. 

(b) Time is of the Essence. Semiconductor and SunEdison acknowledge that time is of the essence in relation to any request for
information, assistance or cooperation made by SunEdison or Semiconductor pursuant to this Section 7.01. Semiconductor and SunEdison acknowledge that failure to conform to the reasonable deadlines set by SunEdison or Semiconductor could cause
irreparable harm. Any information or documents requested pursuant to this Section 7.01 shall be provided in such form as the requesting Company reasonably requests and at or prior to the time reasonably specified by the requesting Company. 

(c) Confidentiality. Any information or documents provided under this Section 7 shall be kept confidential by the Company
receiving the information or documents, except as may otherwise be necessary in connection with the filing of Tax Returns, financial statements, or other similar documents, or in connection with any administrative or judicial proceedings or
investigations, or except as otherwise required by law. Notwithstanding any other provision of this Agreement or any other agreement, in no event shall one Company be required to provide the other Company or any of its Affiliates or any other Person
access to or copies of any information if such action could reasonably be expected to result in the waiver of any Privilege. In addition, in the event either Company determines that the provision of any information to the other Company or any of its
Affiliates could be commercially detrimental, violate any law or agreement or waive any Privilege, the parties shall use reasonable best efforts to permit compliance with its obligations under this Section 7 in a manner that avoids any such
harm or consequence. 
 Section 7.02 Reliance by SunEdison. If any member of the Semiconductor Group supplies information to a
member of the SunEdison Group in connection with a Tax liability and an officer of a member of the SunEdison Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then upon the
written request of such member of the SunEdison Group identifying the information being so relied upon, the chief financial officer of Semiconductor (or any officer of Semiconductor as 

  
 16 








 
designated by the chief financial officer of Semiconductor) shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied
is accurate and complete. 
 Section 7.03 Reliance by Semiconductor. If any member of the SunEdison Group supplies information
to a member of the Semiconductor Group in connection with a Tax liability and an officer of a member of the Semiconductor Group signs a statement or other document under penalties of perjury in reliance upon the accuracy of such information, then
upon the written request of such member of the Semiconductor Group identifying the information being so relied upon, the chief financial officer of SunEdison (or any officer of SunEdison as designated by the chief financial officer of SunEdison)
shall certify in writing that to his or her knowledge (based upon consultation with appropriate employees) the information so supplied is accurate and complete. 

Section 8. Tax Records. 

Section 8.01 Retention of Tax Records. Each Company shall preserve and keep all Tax Records exclusively relating to the assets and
activities of its Group for Pre-Distribution Periods, and SunEdison shall preserve and keep all other Tax Records relating to Taxes of the Groups for Pre-Distribution Tax Periods, for so long as the contents thereof may become material in the
administration of any matter under the Code or other applicable Tax Law, but in any event until the later of (i) the expiration of any applicable statutes of limitations, or (ii) seven years after the Distribution Date (such later date,
the “Retention Date”). After the Retention Date, each Company may dispose of such Tax Records upon sixty (60) Business Days’ prior written notice to the other Company. If, prior to the Retention Date, (a) a Company
reasonably determines that any Tax Records that it would otherwise be required to preserve and keep under this Section 7 are no longer material in the administration of any matter under the Code or other applicable Tax Law and the other Company
agrees in writing to such determination, then such first Company may dispose of such Tax Records upon sixty (60) Business Days’ prior written notice to the other Company. Any notice of an intent to dispose given pursuant to this
Section 7.01 shall include a list of the Tax Records to be disposed of describing in reasonable detail each file, book, or other record accumulation being disposed. The notified Company shall have the opportunity, at its cost and expense, to
copy or remove, within such sixty (60) Business Day period, all or any part of such Tax Records. If, at any time prior to the Retention Date, either Company determines to decomission or otherwise discontinue any computer program or information
technology system used to access or store any Tax Records, then such Company may decomission or discontinue such program or system upon sixty (60) Business Days’ prior notice to the other Company and the other Company shall have the
opportunity, at its cost and expense, to copy, within such sixty (60) Business Day period, all or any part of the underlying data relating to the Tax Records accessed by or stored on such program or system. 

Section 8.02 Preservation of Privilege. No member of the Semiconductor Group shall provide access to, copies of, or otherwise
disclose to any Person any documentation relating to Taxes covered under this Agreement existing as of the date hereof to which Privilege may reasonably be asserted without the prior written consent of SunEdison, such consent not to be unreasonably
withheld, conditioned or delayed. No member of the SunEdison Group shall provide access to, copies of, or otherwise disclose to any Person any documentation relating to 

  
 17 








 
Taxes covered under this Agreement existing as of the date hereof to which Privilege may reasonably be asserted without the prior written consent of Semiconductor, such consent not to be
unreasonably withheld, conditioned or delayed. 
 Section 9. Tax Contests. 

Section 9.01 Notice. Each of the Companies shall provide prompt notice to the other Company of any written communication from a
Tax Authority regarding any pending Tax audit, assessment or proceeding or other Tax Contest of which it becomes aware related to Taxes for Tax Periods for which it is indemnified by the other Company hereunder or for which it may be required to
indemnify the other Company hereunder. Such notice shall attach copies of the pertinent portion of any written communication from a Tax Authority and contain factual information (to the extent known) describing any asserted Tax liability in
reasonable detail and shall be accompanied by copies of any notice and other documents received from any Tax Authority in respect of any such matters. If an indemnified party has knowledge of an asserted Tax liability with respect to a matter for
which it is to be indemnified hereunder and such party fails to give the indemnifying party prompt notice of such asserted Tax liability and the indemnifying party is entitled under this Agreement to contest the asserted Tax liability, then
(i) if the indemnifying party is precluded from contesting the asserted Tax liability in any forum as a result of the failure to give prompt notice, the indemnifying party shall have no obligation to indemnify the indemnified party for any
Taxes arising out of such asserted Tax liability unless and to the extent that the indemnified party can demonstrate that the indemnifying party was not harmed and suffered no detriment as a result of being precluded from contesting the asserted Tax
liability, and (ii) if the indemnifying party is not precluded from contesting the asserted Tax liability in any forum, but such failure to give prompt notice results in a material monetary detriment to the indemnifying party, then any amount
which the indemnifying party is otherwise required to pay the indemnified party pursuant to this Agreement shall be reduced by the amount of such detriment. 

Section 9.02 Control of Tax Contests. 

(a) Tax Returns Prepared by SunEdison. SunEdison shall be entitled to contest, compromise and settle any adjustment that is proposed,
asserted or assessed pursuant to any Tax Contest with respect to any Tax Return described in Section 2.01(a) without the prior consent of Semiconductor; provided that to the extent such Tax Proceeding relates to Semiconductor Taxes or
would reasonably be expected to materially adversely affect the Tax position of any member of the Semiconductor Group for any Post-Distribution Period, SunEdison shall (A) defend such Tax Contest diligently and in good faith, (B) keep
Semiconductor informed in a timely manner of the actions proposed to be taken by SunEdison with respect to the aspects of such Tax Contest that relate to Semiconductor, and (C) permit Semiconductor to participate, at Semiconductor’s own
expense, in the aspects of such Tax Contest that relate to Semiconductor; further provided that SunEdison shall in no event be required to obtain Semiconductor’s consent before compromising, settling, or otherwise disposing of any
aspect of a Tax Contest described in this Section 9.02(a). The failure of SunEdison to take any action specified in the preceding sentence with respect to Semiconductor shall not relieve Semiconductor of any liability and/or obligation which it
may have to SunEdison under this Agreement except to the extent that Semiconductor was actually harmed by such failure, and in no event shall such failure relieve Semiconductor from any other liability or obligation which it may have to SunEdison.


  
 18 








 (b) Tax Returns Prepared by Semiconductor. Except as otherwise provided in
Section 9.02(a), Semiconductor shall be entitled to contest, compromise and settle any adjustment that is proposed, asserted or assessed pursuant to any Tax Contest with respect to any Tax Return described in Section 2.01(b) without the
prior consent of SunEdison; provided that to the extent such Tax Contest relates to SunEdison Taxes or would reasonably be expected to materially adversely affect the Tax position of SunEdison for any Post-Distribution Period, Semiconductor
shall (A) defend such Tax Contest diligently and in good faith, (B) keep SunEdison informed in a timely manner of the actions proposed to be taken by Semiconductor with respect to the aspects of such Tax Contest that relate to SunEdison,
and (C) permit SunEdison to participate, at SunEdison’s own expense, in the aspects of such Tax Contest that relate to SunEdison; further provided that Semiconductor shall in no event be required to obtain SunEdison’s
consent before compromising, settling, or otherwise disposing of any aspect of a Tax Contest described in this Section 9.02(b). The failure of Semiconductor to take any action specified in the preceding sentence with respect to SunEdison shall
not relieve SunEdison of any liability and/or obligation which it may have to Semiconductor under this Agreement except to the extent that SunEdison was actually harmed by such failure, and in no event shall such failure relieve SunEdison from any
other liability or obligation which it may have to Semiconductor. 
 Section 10. Effective Date. This Agreement shall be effective as
of the date hereof. 
 Section 11. Survival of Obligations. The representations, warranties, covenants and agreements set forth in
this Agreement shall be unconditional and absolute and shall remain in effect without limitation as to time. 
 Section 12.
Disagreements. 
 Section 12.01 Discussion. The Companies mutually desire that friendly collaboration will continue
between them. Accordingly, they will try, and they will cause their respective Affiliates to try, to resolve in an amicable manner all disagreements and misunderstandings connected with their respective rights and obligations under this Agreement,
including any amendments hereto. In furtherance thereof, and except as otherwise provided in this Agreement, in the event of any dispute or disagreement (a “Dispute”) between any member of the SunEdison Group and any member of the
Semiconductor Group as to the interpretation of any provision of this Agreement or the performance of obligations hereunder, the Tax departments of the Companies shall negotiate in good faith to resolve the Dispute. 

Section 12.02 Escalation. If such good faith negotiations do not resolve the Dispute, then the matter, upon written request of
either Company, will be referred for resolution to representatives of the parties at a senior level of management of the parties pursuant to the procedures set forth in Section 3.2 of the Separation Agreement. 

Section 12.03 Referral to Tax Advisor. If the parties are not able to resolve the Dispute through the escalation process referred
to in Section 12.02, then the matter will be referred to the Tax Advisor to act as an arbitrator in order to resolve the Dispute. The Tax Advisor may, in its 

  
 19 








 
discretion, obtain the services of any third-party appraiser, accounting firm or consultant that the Tax Advisor deems necessary to assist it in resolving such disagreement. The Tax Advisor shall
furnish written notice to the Companies of its resolution of any such Dispute as soon as practical, but in any event no later than thirty (30) Business Days after its acceptance of the matter for resolution. Any such resolution by the Tax
Advisor will be conclusive and binding on the Companies. Following receipt of the Tax Advisor’s written notice to the Companies of its resolution of the Dispute, the Companies shall each take or cause to be taken any action necessary to
implement such resolution of the Tax Advisor. Each Company shall pay its own fees and expenses (including the fees and expenses of its representatives) incurred in connection with the referral of the matter to the Tax Advisor (and the Preliminary
Tax Advisors, if any). All fees and expenses of the Tax Advisor (and the Preliminary Tax Advisors, if any) in connection with such referral shall be shared equally by the Companies. 

Section 12.04 Injunctive Relief. Nothing in this Section 12 will prevent either Company from seeking injunctive relief if any
delay resulting from the efforts to resolve the Dispute through the process set forth above could result in serious and irreparable injury to either Company. Notwithstanding anything to the contrary in this Agreement, SunEdison and Semiconductor are
the only members of their respective Groups entitled to commence a Dispute resolution procedure under this Agreement, and each of SunEdison and Semiconductor will cause its respective Group members not to commence any Dispute resolution procedure
other than through such Company as provided in this Section 12. 
 Section 12.05 Failure to Agree on a Tax Advisor. In the
event both KPMG LLP and PricewaterhouseCoopers LLP are unable to serve as the Tax Advisor, and the Companies are unable to agree upon a Tax Advisor within fifteen (15) Business Days following the completion of the escalation process referred to
in Section 12.02, the Companies shall each separately retain an independent, nationally recognized law or accounting firm (each, a “Preliminary Tax Advisor”), which Preliminary Tax Advisors shall jointly select a Tax Advisor on
behalf of the Companies to act as an arbitrator in order to resolve the Dispute. 
 Section 13. Late Payments. Any amount owed by one
party to another party under this Agreement which is not paid when due shall accrue interest at a rate per annum equal to the Prime Rate plus two percent (2%), compounded semiannually, from the due date of the payment to the date paid. 

Section 14. Expenses. Except as otherwise provided in this Agreement, each Company and its Affiliates shall bear their own expenses
incurred in connection with preparation of Tax Returns, Tax Contests, and other matters related to Taxes under the provisions of this Agreement. 

Section 15. General Provisions.

Section 15.07 Integration. This Agreement contains the entire agreement between the Companies with respect to the subject matter
hereof and supersedes all other agreements, whether or not written, in respect of any Tax covered herein between or among any member or members of the SunEdison Group, on the one hand, and any member or members of the Semiconductor Group, on the
other hand. All such other agreements shall be of no further effect between the Companies and any rights or obligations existing thereunder shall be fully and finally settled, calculated as of the date hereof. In the event of any inconsistency
between this Agreement and the Separation Agreement, or any other agreements relating to the transactions contemplated by the Separation Agreement, with respect to the subject matter hereof, the provisions of this Agreement shall control. 

Section 15.08 Construction. The language in all parts of this Agreement shall in all cases be construed according to its fair
meaning and shall not be strictly construed for or against any party. The captions, titles and headings included in this Agreement are for convenience only, and do not affect this Agreement’s construction or interpretation. Unless otherwise
indicated, all “Section” references in this Agreement are to sections of this Agreement. 
 Section 15.09 No Double
Recovery. No provision of this Agreement shall be construed to provide an indemnity or other recovery for any costs, damages, or other amounts for which the damaged party has been fully compensated under any other provision of this Agreement or

recovering under the remedies provided in this Agreement. 
 Section 15.10 Counterparts. The parties may execute this Agreement
in multiple counterparts, each of which constitutes an original as against the party that signed it, and all of which together constitute one agreement. This Agreement is effective upon delivery of one executed counterpart from each party to the
other party. The signatures of the parties need not appear on the same counterpart. The delivery of signed counterparts by facsimile or email transmission that includes a copy of the sending party’s signature is as effective as signing and
delivering the counterpart in person. 
 Section 15.11 Governing Law. The internal laws of the State of New York (without
reference to its principles of conflicts of law), including Sections 5-1401 and 5-1402 of the New 

  
 22 








 
York General Obligations Law, govern the construction, interpretation and other matters arising out of or in connection with this Agreement (whether arising in contract, tort, equity or
otherwise). 
 Section 15.12 Jurisdiction. If any dispute arises out of or in connection with this Agreement, except as
expressly contemplated by another provision of this Agreement, the parties irrevocably (and the parties will cause each other member of their respective Group to irrevocably) (a) consent and submit to the exclusive jurisdiction of federal and
state courts located in the State of New York, borough of Manhattan, (b) waive any objection to that choice of forum based on venue or to the effect that the forum is not convenient, and (c) WAIVE TO THE FULLEST EXTENT PERMITTED BY LAW ANY

Section 15.14 Semiconductor Subsidiaries. If, at any time, Semiconductor acquires or creates one or more subsidiaries that are
includable in the Semiconductor Group, they shall be subject to this Agreement and all references to the Semiconductor Group herein shall thereafter include a reference to such subsidiaries. 

Section 15.15 Successors. This Agreement shall be binding on and inure to the benefit of any successor by merger, acquisition of
assets, or otherwise, to any of the parties hereto (including but not limited to any successor of SunEdison or Semiconductor succeeding to the Tax attributes of either under Section 381 of the Code), to the same extent as if such successor had
been an original party to this Agreement. 
 Section 15.16 Injunctions. The parties acknowledge that irreparable damage would
occur in the event that any of the provisions of this Agreement were not performed in accordance with its specific terms or were otherwise breached. The parties hereto shall be entitled to an injunction or injunctions to prevent breaches of the
provisions of this Agreement and to enforce specifically the terms and provisions hereof in any court having jurisdiction, such remedy being in addition to any other remedy to which they may be entitled at law or in equity.
