		Re:	Additional Call Option Transaction



 


The purpose of this letter
agreement (this “Confirmation”) is to confirm the terms and conditions of the call option transaction entered
into between JPMorgan Chase Bank, National Association, London Branch (“Dealer”) and Aceto Corporation
(“Counterparty”) as of the Trade Date specified below (the “Transaction”). This letter
agreement constitutes a “Confirmation” as referred to in the ISDA Master Agreement specified below. This Confirmation
shall replace any previous agreements and serve as the final documentation for the Transaction.


 


The definitions and provisions
contained in the 2002 ISDA Equity Derivatives Definitions (the “Equity Definitions”), as published by the International
Swaps and Derivatives Association, Inc. (“ISDA”) are incorporated into this Confirmation. In the event of any
inconsistency between the Equity Definitions and this Confirmation, this Confirmation shall govern. Certain defined terms used
herein are based on terms that are defined in the Offering Memorandum dated November 10, 2015 (the “Offering Memorandum”)
relating to the Convertible Senior Notes due 2020 (as originally issued by Counterparty, the “Convertible Notes”
and each USD 1,000 principal amount of Convertible Notes, a “Convertible Note”) issued by Counterparty in an
aggregate initial principal amount of USD 125,000,000 (as increased by an aggregate principal amount of USD 18,750,000 pursuant
to the exercise by the Initial Purchasers (as defined herein) of their option to purchase additional Convertible Notes pursuant
to the Purchase Agreement (as defined herein)) pursuant to an Indenture dated November 16, 2015 between Counterparty and Citibank,
N.A., as trustee (the “Indenture”). In the event of any inconsistency between the terms defined in the Offering
Memorandum, the Indenture and this Confirmation, this Confirmation shall govern. The parties acknowledge that this Confirmation
is entered into on the date hereof with the understanding that (i) definitions set forth in the Indenture which are also defined
herein by reference to the Indenture and (ii) sections of the Indenture that are referred to herein will conform to the descriptions
thereof in the Offering Memorandum. If any such definitions in the Indenture or any such sections of the Indenture differ from
the descriptions thereof in the Offering Memorandum, the descriptions thereof in the Offering Memorandum will govern for purposes
of this Confirmation. The parties further acknowledge that the Indenture section numbers used herein are based on the Indenture
as executed. Subject to the foregoing, references to the Indenture herein are references to the Indenture as in effect on the date
of its execution, and if the Indenture is amended or supplemented following such date (other than any amendment or supplement (x)
pursuant to Section 10.01(h) of the Indenture that, as determined by the Calculation Agent acting in good faith and in a commercially
reasonable manner, conforms the Indenture to the description of Convertible Notes in the Offering Memorandum or (y) pursuant to
Section 14.07 of the Indenture, subject, in the case of this clause (y), to the second paragraph under “Method of Adjustment”
in Section 3), any such amendment or supplement will be disregarded for purposes of this Confirmation unless the parties agree
otherwise in writing.


 


Each party is hereby advised,
and each such party acknowledges, that the other party has engaged in, or refrained from engaging in, substantial financial transactions
and has taken other material actions in reliance upon the parties’ entry into the Transaction to which this Confirmation
relates on the terms and conditions set forth below.

Agreement (the “Agreement”) as if Dealer and Counterparty had executed an agreement in such form (but without
any Schedule except for the election of the laws of the State of New York as the governing law (without reference to choice of
law doctrine)) on the Trade Date. In the event of any inconsistency between provisions of the Agreement and this Confirmation,

	 	(i)	cash (the “Combination Settlement Cash Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of (A) an amount (the “Daily Combination Settlement Cash Amount”) equal to the lesser of (1) the product of (x) the Applicable Percentage and (y) the Specified Cash Amount minus USD 1,000 and (2) the Daily Option Value, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in clause (A) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Cash Amount for such Valid Day shall be deemed to be zero; and


 




    	 	-5-	 



     


    

 


	 	(ii)	Shares (the “Combination Settlement Share Amount”) equal to the sum, for each Valid Day during the Settlement Averaging Period for such Option, of a number of Shares for such Valid Day (the “Daily Combination Settlement Share Amount”) equal to (A) (1) the Daily Option Value on such Valid Day minus the Daily Combination Settlement Cash Amount for such Valid Day, divided by (2) the Relevant Price on such Valid Day, divided by (B) the number of Valid Days in the Settlement Averaging Period; provided that if the calculation in sub-clause (A)(1) above results in zero or a negative number for any Valid Day, the Daily Combination Settlement Share Amount for such Valid Day shall be deemed to be zero;


 


	 	provided that in no event shall the sum of (x) the Combination Settlement Cash Amount for any Option and (y) the Combination Settlement Share Amount for such Option multiplied by the Applicable Limit Price on the Settlement Date for such Option, exceed the Applicable Limit for such Option.
	 	 
	 	Dealer will pay cash in lieu of delivering any fractional Shares to be delivered with respect to any Combination Settlement Share Amount valued at the Relevant Price for the last Valid Day of the Settlement Averaging Period.

	Daily Option Value:	For any Valid Day, an amount equal to (i) the Option Entitlement on such Valid Day, multiplied by (ii) the Relevant Price on such Valid Day less the Strike Price on such Valid Day; provided that if the calculation contained in clause (ii) above results in a negative number, the Daily Option Value for such Valid Day shall be deemed to be zero.  In no event will the Daily Option Value be less than zero.
	 	 
	Make-Whole Adjustment:	Notwithstanding anything to the contrary herein, in respect of any exercise of Options relating to a conversion of Convertible Notes for which additional Shares will be added to the “Conversion Rate” (as defined in the Indenture) as determined pursuant to Section 14.03 of the Indenture, the Daily Option Value shall be calculated as if the Option Entitlement included the Applicable Percentage of the number of such additional Shares as determined with reference to the adjustment set forth in such Section 14.03 of the Indenture; provided that if the sum of (i) the product of (a) the number of Shares (if any) deliverable by Dealer to Counterparty per exercised Option and (b) the Applicable Limit Price on the Settlement Date and (ii) the amount of cash (if any) payable by Dealer to Counterparty per exercised Option would otherwise exceed the amount per Option, as determined by the Calculation Agent (acting in good faith and in a commercially reasonable manner), that would be payable by Dealer under Section 6 of the Agreement if (x) the relevant  Conversion Date were an Early Termination Date resulting from an Additional Termination Event with respect to which the Transaction was the sole Affected Transaction and Counterparty was the sole Affected Party and (y) Section 14.03 of the Indenture were deleted, then each Daily Option Value shall be proportionately reduced to the extent necessary to eliminate such excess.

For the avoidance of doubt, Dealer shall not have any delivery or payment obligation hereunder, and no adjustment shall be made to the terms of the Transaction, on account of (x) any distribution of cash, property or securities by Counterparty to holders of the Convertible Notes (upon conversion or otherwise) or (y) any other transaction in which holders of the Convertible Notes are entitled to participate, in each case, in lieu of an adjustment under the Indenture of the type referred to in the immediately preceding sentence (including, without limitation, pursuant to the fourth sentence of the first paragraph of Section 14.04(c) of the Indenture or the third sentence of the second paragraph of Section 14.04(d) of the Indenture).

    	 	-9-	 



     


    

 


	Dilution Adjustment Provisions:	Sections 14.04(a), (b), (c), (d) and (e) and Section 14.05 of the Indenture.

	Nationalization, Insolvency or Delisting:	Cancellation and Payment (Calculation Agent Determination); provided that, in addition to the provisions of Section 12.6(a)(iii) of the Equity Definitions, it will also constitute a Delisting if the Exchange is located in the United States and the Shares are not immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors); if the Shares are immediately re-listed, re-traded or re-quoted on any of the New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors), such exchange or quotation system shall thereafter be deemed to be the Exchange.

If promptly following such written explanation Counterparty so requests, the Calculation Agent shall, to the extent permitted by applicable legal, regulatory or self-regulatory requirements and related policies and procedures applicable to the Calculation Agent (as reasonably determined by the Calculation Agent), discuss the related judgment, determination or calculation with Counterparty in good faith; provided that, for the avoidance of doubt and notwithstanding the obligation of the Calculation Agent to discuss a judgment, determination or calculation with Counterparty as set forth in this paragraph, any such judgment, determination or calculation by the Calculation Agent shall be final and conclusive.

		8.	Representations and Warranties of Counterparty.



 


Each of the representations and warranties
of Counterparty set forth in Section 1 of the Purchase Agreement (the “Purchase Agreement”), dated as
of November 10, 2015, among Counterparty, Wells Fargo Securities, LLC and J.P. Morgan Securities LLC, as representatives of the
Initial Purchasers party thereto (the “Initial Purchasers”), are true and correct and are hereby deemed to be
repeated to Dealer as if set forth herein. Counterparty hereby further represents and warrants to Dealer on the date hereof and
on and as of the Premium Payment Date that:


 


		(a)	Counterparty has all necessary corporate power and authority to execute, deliver and perform its
obligations in respect of the Transaction; such execution, delivery and performance have been duly authorized by all necessary
corporate action on Counterparty’s part; and this Confirmation has been duly and validly executed and delivered by Counterparty
and constitutes its valid and binding obligation, enforceable against Counterparty in accordance with its terms, subject to applicable
bankruptcy, insolvency, fraudulent conveyance, reorganization, moratorium and similar laws affecting creditors’ rights and
remedies generally, and subject, as to enforceability, to general principles of equity, including principles of commercial reasonableness,
good faith and fair dealing (regardless of whether enforcement is sought in a proceeding at law or in equity) and except that rights
to indemnification and contribution hereunder may be limited by federal or state securities laws or public policy relating thereto.



 




    	 	-13-	 



     


    

		(b)	Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations
of Counterparty hereunder will conflict with or result in a breach of the certificate of incorporation or by-laws (or any equivalent
documents) of Counterparty, or any applicable law or regulation, or any order, writ, injunction or decree of any court or governmental
authority or agency, or any agreement or instrument to which Counterparty or any of its subsidiaries is a party or by which Counterparty
or any of its subsidiaries is bound or to which Counterparty or any of its subsidiaries is subject, or constitute a default under,
or result in the creation of any lien under, any such agreement or instrument.



 


		(c)	No consent, approval, authorization, or order of, or filing with, any governmental agency or body
or any court is required in connection with the execution, delivery or performance by Counterparty of this Confirmation, except
such as have been obtained or made and such as may be required under the Securities Act or state securities laws.



 


		(d)	Counterparty is not and, after consummation of the transactions contemplated hereby, will not be
required to register as an “investment company” as such term is defined in the Investment Company Act of 1940, as amended.



 


		(e)	Counterparty is an “eligible contract participant” (as such term is defined in Section
1a(18) of the Commodity Exchange Act, as amended, other than a person that is an eligible contract participant under Section 1a(18)(C)
of the Commodity Exchange Act).



 


		(f)	Each of it and its affiliates is not, on the date hereof, in possession of any material non-public
information with respect to Counterparty or the Shares.



 


		(g)	No state or local (including any non-U.S. jurisdiction’s) law, rule, regulation or regulatory
order applicable to the Shares would give rise to any reporting, consent, registration or other requirement (including without
limitation a requirement to obtain prior approval from any person or entity) as a result of Dealer or its affiliates owning or
holding (however defined) Shares.



 


		(h)	Counterparty (A) is capable of evaluating investment risks independently, both in general and with
regard to all transactions and investment strategies involving a security or securities; (B) will exercise independent judgment
in evaluating the recommendations of any broker-dealer or its associated persons, unless it has otherwise notified the broker-dealer
in writing; and (C) has total assets of at least $50 million.



 


		9.	Other Provisions.



 


		(a)	Opinions. Counterparty shall deliver to Dealer an opinion of counsel, dated as of
the Effective Date, with respect to the matters set forth in Sections 8(a) through (c) of this Confirmation. Delivery of such opinion
to Dealer shall be a condition precedent for the purpose of Section 2(a)(iii) of the Agreement with respect to each obligation
of Dealer under Section 2(a)(i) of the Agreement.



 




    	 	-14-	 



     


    

 


		(b)	Repurchase Notices. Counterparty shall, on any day on which Counterparty effects
any repurchase of Shares, promptly give Dealer a written notice of such repurchase (a “Repurchase Notice”) on
such day if following such repurchase, the number of outstanding Shares as determined on such day is (i) less than 28.0 million
(in the case of the first such notice) or (ii) thereafter more than 1.4 million less than the number of Shares included in the
immediately preceding Repurchase Notice. Counterparty agrees to indemnify and hold harmless Dealer and its affiliates and their
respective officers, directors, employees, affiliates, advisors, agents and controlling persons (each, an “Indemnified
Person”) from and against any and all reasonable losses (including losses relating to Dealer’s hedging activities
as a consequence of becoming, or of the risk of becoming, a Section 16 “insider”, including without limitation, any
forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with respect to the
Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorney’s fees), joint or several,
which an Indemnified Person may become subject to, solely as a result of Counterparty’s failure to provide Dealer with a
Repurchase Notice on the day and in the manner specified in this paragraph, and to reimburse, within 30 days, upon written request,
each of such Indemnified Persons for any reasonable legal or other expenses incurred (each as reasonably documented to Counterparty)
in connection with investigating, preparing for, providing testimony or other evidence in connection with or defending any of the
foregoing. If any suit, action, proceeding (including any governmental or regulatory investigation), claim or demand shall be brought
or asserted against the Indemnified Person as a result of Counterparty’s failure to provide Dealer with a Repurchase Notice
in accordance with this paragraph, such Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon
request of the Indemnified Person, shall retain counsel reasonably satisfactory to the Indemnified Person to represent the Indemnified
Person and any others Counterparty may designate in such proceeding and shall pay the fees and expenses of such counsel related
to such proceeding. Counterparty shall not be liable for any settlement of any proceeding contemplated by this paragraph that is
effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Counterparty
agrees to indemnify any Indemnified Person from and against any reasonable loss or liability by reason of such settlement or judgment.
Counterparty shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened
proceeding contemplated by this paragraph that is in respect of which any Indemnified Person is or could have been a party and
indemnity could have been sought hereunder by such Indemnified Person, unless such settlement includes an unconditional release
of such Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably satisfactory
to such Indemnified Person. If the indemnification provided for in this paragraph is unavailable to an Indemnified Person or insufficient
in respect of any losses, claims, damages or liabilities referred to therein, then Counterparty hereunder, in lieu of indemnifying
such Indemnified Person thereunder, shall contribute to the amount paid or payable by such Indemnified Person as a result of such
losses, claims, damages or liabilities. The remedies provided for in this paragraph (b) are not exclusive and shall not limit any
rights or remedies which may otherwise be available to any Indemnified Person at law or in equity. The indemnity and contribution
agreements contained in this paragraph shall remain operative and in full force and effect regardless of the termination of the
Transaction.



 


		(c)	Regulation M. Counterparty is not on the Trade Date engaged in a distribution, as
such term is used in Regulation M under the Securities Exchange Act of 1934, as amended (the “Exchange Act”),
of any securities of Counterparty, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10)
and 102(b)(7) of Regulation M. Counterparty shall not, until the second Scheduled Trading Day immediately following the Effective
Date, engage in any such distribution.



 


		(d)	No Manipulation. Counterparty is not entering into the Transaction to create actual
or apparent trading activity in the Shares (or any security convertible into or exchangeable for the Shares) or to raise or depress
or otherwise manipulate the price of the Shares (or any security convertible into or exchangeable for the Shares) or otherwise
in violation of the Exchange Act.



 


		(e)	Transfer or Assignment.



 


		(i)	Counterparty shall have the right to transfer or assign its rights and obligations hereunder with
respect to all, but not less than all, of the Options hereunder (such Options, the “Transfer Options”); provided
that such transfer or assignment shall be subject to reasonable conditions that Dealer may impose, including but not limited, to
the following conditions:



 


		(A)	With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification
obligations pursuant to Section 9(b) or any obligations under Section 9(n) or 9(s) of this Confirmation;



 


		(B)	Any Transfer Options shall only be transferred or assigned to a third party that is a United States
person (as defined in the Internal Revenue Code of 1986, as amended);



 




    	 	-15-	 



     


    

 


		(C)	Such transfer or assignment shall be effected on terms, including any reasonable undertakings by
such third party (including, but not limited to, an undertaking with respect to compliance with applicable securities laws in a
manner that, in the reasonable and good faith judgment of Dealer, will not expose Dealer to material risks under applicable securities
laws) and execution of any documentation and delivery of legal opinions with respect to securities laws and other matters by such
third party and Counterparty, as are requested and reasonably satisfactory to Dealer;



 


		(D)	Dealer will not, as a result of such transfer and assignment, be required to pay the transferee
on any payment date an amount under Section 2(d)(i)(4) of the Agreement greater than an amount that Dealer would have been required
to pay to Counterparty in the absence of such transfer and assignment;



 


		(E)	An Event of Default, Potential Event of Default or Termination Event will not occur as a result
of such transfer and assignment;



 


		(F)	Without limiting the generality of clause (B), Counterparty shall cause the transferee to make
such Payee Tax Representations and to provide such tax documentation as may be reasonably requested by Dealer to permit Dealer
to determine that results described in clauses (D) and (E) will not occur upon or after such transfer and assignment; and



 


		(G)	Counterparty shall be responsible for all reasonable costs and expenses, including reasonable outside
counsel fees, incurred by Dealer in connection with such transfer or assignment.



 


		(ii)	Dealer may, without Counterparty’s consent, transfer or assign all or any part of its rights
or obligations under the Transaction (A) to any affiliate of Dealer (1) that has a long-term issuer rating that is equal to or
better than Dealer’s credit rating at the time of such transfer or assignment, or (2) whose obligations hereunder will be
guaranteed, pursuant to the terms of a customary guarantee in a form used by Dealer generally for similar transactions with parties
similar to Counterparty (with such determination made by Dealer in good faith and in a commercially reasonable manner), by Dealer
or Dealer’s ultimate parent, or (B) to any other third party with a long-term issuer rating equal to or better than the lesser
of (1) the credit rating of Dealer at the time of the transfer and (2) A- by Standard and Poor’s Rating Group, Inc. or its
successor (“S&P”), or A3 by Moody’s Investor Service, Inc. (“Moody’s”) or,
if either S&P or Moody’s ceases to rate such debt, at least an equivalent rating or better by a substitute rating agency
mutually agreed by Counterparty and Dealer. If at any time at which (A) the Section 16 Percentage exceeds 7.5%, (B) the Option
Equity Percentage exceeds 14.5%, or (C) the Share Amount exceeds the Applicable Share Limit (if any applies) (any such condition
described in clauses (A), (B) or (C), an “Excess Ownership Position”), Dealer is unable after using its commercially
reasonable efforts to effect a transfer or assignment of Options to a third party on pricing terms reasonably acceptable to Dealer
and within a time period reasonably acceptable to Dealer such that no Excess Ownership Position exists, then Dealer may designate
any Exchange Business Day as an Early Termination Date with respect to a portion of the Transaction (the “Terminated Portion”),
such that following such partial termination no Excess Ownership Position exists. In the event that Dealer so designates an Early
Termination Date with respect to a portion of the Transaction, a payment shall be made pursuant to Section 6 of the Agreement as
if (1) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Transaction and
a Number of Options equal to the number of Options underlying the Terminated Portion, (2) Counterparty were the sole Affected Party
with respect to such partial termination and (3) the Terminated Portion were the sole Affected Transaction (and, for the avoidance
of doubt, the provisions of Section 9(l) shall apply to any amount that is payable by Dealer to Counterparty pursuant to this sentence
as if Counterparty was not the Affected Party). The “Section 16 Percentage” as of any day is the fraction, expressed
as a percentage, (A) the numerator of which is the number of Shares that Dealer and any of its affiliates or any other person subject
to aggregation with Dealer for purposes of the “beneficial ownership” test under Section 13 of the Exchange Act, or
any “group” (within the meaning of Section 13 of the Exchange Act) of which Dealer is or may be deemed to be a part
beneficially owns (within the meaning of Section 13 of the Exchange Act), without duplication, on such day (or, to the extent that
for any reason the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results
in a higher number, such higher number) and (B) the denominator of which is the number of Shares outstanding on such day. The “Option
Equity Percentage” as of any day is the fraction, expressed as a percentage, (A) the numerator of which is the sum of
(1) the product of the Number of Options and the Option Entitlement and (2) the aggregate number of Shares underlying any other
call option transaction sold by Dealer to Counterparty, and (B) the denominator of which is the number of Shares outstanding. The
“Share Amount” as of any day is the number of Shares that Dealer and any person whose ownership position would
be aggregated with that of Dealer (Dealer or any such person, a “Dealer Person”) under any law, rule, regulation,
regulatory order or organizational documents or contracts of Counterparty that are, in each case, applicable to ownership of Shares
(“Applicable Restrictions”), owns, beneficially owns, constructively owns, controls, holds the power to vote
or otherwise meets a relevant definition of ownership under any Applicable Restriction, as determined by Dealer in its reasonable
discretion. The “Applicable Share Limit” means a number of Shares equal to (A) the minimum number of Shares
that could give rise to reporting or registration obligations or other requirements (including obtaining prior approval from any
person or entity) of a Dealer Person, or could result in an adverse effect on a Dealer Person, under any Applicable Restriction,
as determined by Dealer in its reasonable discretion, minus (B) 1% of the number of Shares outstanding.



 




    	 	-16-	 



     


    

 


		(iii)	Notwithstanding any other provision in this Confirmation to the contrary requiring or allowing
Dealer to purchase, sell, receive or deliver any Shares or other securities, or make or receive any payment in cash, to or from
Counterparty, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such Shares or other securities,
or to make or receive such payment in cash, and otherwise to perform Dealer’s obligations in respect of the Transaction and
any such designee may assume such obligations. Dealer shall be discharged of its obligations to Counterparty to the extent of any
such performance.



 


		(f)	Staggered Settlement. If upon advice of counsel with respect to applicable legal
and regulatory requirements, including any requirements relating to Dealer’s hedging activities hereunder, Dealer reasonably
determines that it would not be practicable or advisable to deliver, or to acquire Shares to deliver, any or all of the Shares
to be delivered by Dealer on any Settlement Date for the Transaction, Dealer may, by notice to Counterparty on or prior to any
Settlement Date (a “Nominal Settlement Date”), elect to deliver the Shares on two or more dates (each, a “Staggered
Settlement Date”) as follows:



 


		(i)	in such notice, Dealer will specify to Counterparty the related Staggered Settlement Dates (the
first of which will be such Nominal Settlement Date and the last of which will be no later than the twentieth (20th) Exchange Business
Day following such Nominal Settlement Date) and the number of Shares that it will deliver on each Staggered Settlement Date;



 


		(ii)	the aggregate number of Shares that Dealer will deliver to Counterparty hereunder on all such Staggered
Settlement Dates will equal the number of Shares that Dealer would otherwise be required to deliver on such Nominal Settlement
Date; and



 


		(iii)	if the Net Share Settlement terms or the Combination Settlement terms set forth above were to apply
on the Nominal Settlement Date, then the Net Share Settlement terms or the Combination Settlement terms, as the case may be, will
apply on each Staggered Settlement Date, except that the Shares otherwise deliverable on such Nominal Settlement Date will be allocated
among such Staggered Settlement Dates as specified by Dealer in the notice referred to in clause (i) above.



 




    	 	-17-	 



     


    

 


		(g)	Role of Agent. Each party agrees and acknowledges that (i) J.P. Morgan Securities
LLC, an affiliate of Dealer (“JPMS”), has acted solely as agent and not as principal with respect to the Transaction
and (ii) JPMS has no obligation or liability, by way of guaranty, endorsement or otherwise, in any manner in respect of the Transaction
(including, if applicable, in respect of the settlement thereof). Each party agrees it will look solely to the other party (or
any guarantor in respect thereof) for performance of such other party’s obligations under the Transaction.



 


		(h)	Dividends. If at any time during the period from and including the Effective Date,
to but excluding the Expiration Date, (i) an ex-dividend date for a regular quarterly cash dividend occurs with respect to the
Shares (an “Ex-Dividend Date”), and that dividend is less than the Regular Dividend on a per Share basis or
(ii) if no Ex-Dividend Date for a regular quarterly cash dividend occurs with respect to the Shares in any quarterly dividend period
of Counterparty, then the Calculation Agent will make a corresponding adjustment to any one or more of the Strike Price, Number
of Options, Option Entitlement and/or any other variable relevant to the exercise, settlement or payment for the Transaction to
preserve the fair value of the Options to Dealer after taking into account such dividend or lack thereof. “Regular Dividend”
shall mean USD 0.06 per Share per quarter. Upon any adjustment to the Initial Dividend Threshold (as defined in the Indenture)
for the Convertible Notes pursuant to the Indenture, the Calculation Agent will make a corresponding adjustment to the Regular
Dividend for the Transaction.



 


		(i)	Additional Termination Event. Notwithstanding anything to the contrary in this Confirmation
if an event of default with respect to Counterparty occurs under the terms of the Convertible Notes as set forth in Section 6.01
of the Indenture and results in the acceleration of Counterparty’s obligations thereunder, then such event of default shall
constitute an Additional Termination Event applicable to the Transaction and, with respect to such Additional Termination Event,
(A) Counterparty shall be deemed to be the sole Affected Party, (B) the Transaction shall be the sole Affected Transaction and
(C) Dealer shall be the party entitled to designate an Early Termination Date pursuant to Section 6(b) of the Agreement.



 


		(j)	Amendments to Equity Definitions.



 


		(i)	Section 12.6(a)(ii) of the Equity Definitions is hereby amended by (1) deleting from the fourth
line thereof the word “or” after the word “official” and inserting a comma therefor, and (2) deleting the
semi-colon at the end of subsection (B) thereof and inserting the following words therefor “or (C) the occurrence of any
of the events specified in Section 5(a)(vii)(1) through (9) of the ISDA Master Agreement with respect to that Issuer.”



 


		(ii)	Section 12.9(b)(i) of the Equity Definitions is hereby amended by (1) replacing “either party
may elect” with “Dealer may elect” and (2) replacing “notice to the other party” with “notice
to Counterparty” in the first sentence of such section.



 


		(k)	Setoff. In addition to and without limiting any rights of set-off that a party hereto
may have as a matter of law, pursuant to contract or otherwise, upon the occurrence of an Early Termination Date, Dealer (and only
Dealer)  shall have the right to set off any obligation that it may have to Counterparty under this Confirmation, including
without limitation any obligation to make any payment of cash or delivery of Shares to Counterparty, against any obligation Counterparty
may have to Dealer under any other agreement between Dealer and Counterparty relating to Shares (each such contract or agreement,
a “Separate Agreement”), including without limitation any obligation to make a payment of cash or a delivery
of Shares or any other property or securities. For this purpose, Dealer shall be entitled to convert any obligation (or the relevant
portion of such obligation) denominated in one currency into another currency at the rate of exchange at which it would be able
to purchase the relevant amount of such currency, and to convert any obligation to deliver any non-cash property into an obligation
to deliver cash in an amount calculated by reference to the market value of such property as of the Early Termination Date, as
determined by the Calculation Agent in its sole discretion; provided that in the case of a set-off of any obligation to
release or deliver assets against any right to receive fungible assets, such obligation and right shall be set off in kind and;
provided further that in determining the value of any obligation to deliver Shares, the value at any time of such obligation
shall be determined by reference to the market value of the Shares at such time, as determined in good faith by the Calculation
Agent. If an obligation is unascertained at the time of any such set-off, the Calculation Agent may in good faith estimate the
amount or value of such obligation, in which case set-off will be effected in respect of that estimate, and the relevant party
shall account to the other party at the time such obligation or right is ascertained. For the avoidance of doubt and notwithstanding
anything to the contrary provided in this Section 9(k), in the event of bankruptcy or liquidation of either Counterparty or Dealer
neither party shall have the right to set off any obligation that it may have to the other party under the Transaction against
any obligation such other party may have to it, whether arising under the Agreement, this Confirmation or any other agreement between
the parties hereto, by operation of law or otherwise.



 




    	 	-18-	 



     


    

 


		(l)	Alternative Calculations and Payment on Early Termination and on Certain Extraordinary Events.
If (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated with
respect to the Transaction or (b) the Transaction is cancelled or terminated upon the occurrence of an Extraordinary Event (except
as a result of (i) a Nationalization, Insolvency or Merger Event in which the consideration to be paid to holders of Shares consists
solely of cash, (ii) a Merger Event or Tender Offer that is within Counterparty’s control, or (iii) an Event of Default in
which Counterparty is the Defaulting Party or a Termination Event in which Counterparty is the Affected Party other than an Event
of Default of the type described in Section 5(a)(iii), (v), (vi), (vii) or (viii) of the Agreement or a Termination Event of the
type described in Section 5(b) of the Agreement, in each case that resulted from an event or events outside Counterparty’s
control), and if Dealer would owe any amount to Counterparty pursuant to Section 6(d)(ii) of the Agreement or any Cancellation
Amount pursuant to Article 12 of the Equity Definitions (any such amount, a “Payment Obligation”), then Dealer
shall satisfy the Payment Obligation by the Share Termination Alternative (as defined below), unless (a) Counterparty gives
irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading Day, no later than 12:00 p.m. (New York
City time) on the Merger Date, Tender Offer Date, Announcement Date (in the case of a Nationalization, Insolvency or Delisting),
Early Termination Date or date of cancellation, as applicable, of its election that the Share Termination Alternative shall not
apply, (b) Counterparty remakes the representation set forth in Section 8(f) as of the date of such election and (c) Dealer agrees,
in its sole discretion, to such election, in which case the provisions of Section 12.7 or Section 12.9 of the Equity Definitions,
or the provisions of Section 6(d)(ii) of the Agreement, as the case may be, shall apply.



 


	Share Termination Alternative:	If applicable, Dealer shall deliver to Counterparty the Share Termination Delivery Property on, or within a commercially reasonable period of time after, the date when the relevant Payment Obligation would otherwise be due pursuant to Section 12.7 or 12.9 of the Equity Definitions or Section 6(d)(ii) and 6(e) of the Agreement, as applicable, in satisfaction of such Payment Obligation in the manner reasonably requested by Counterparty free of payment.
	 	 
	Share Termination Delivery Property:	A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal to the Payment Obligation divided by the Share Termination Unit Price.  The Calculation Agent shall adjust the Share Termination Delivery Property by replacing any fractional portion of a security therein with an amount of cash equal to the value of such fractional security based on the values used to calculate the Share Termination Unit Price.
	 	 
	Share Termination Unit Price:	The value to Dealer of property contained in one Share Termination Delivery Unit, as determined by the Calculation Agent in its good faith discretion by commercially reasonable means and notified by the Calculation Agent to Dealer at the time of notification of the Payment Obligation. For the avoidance of doubt, the parties agree that in determining the Share Termination Delivery Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share Termination Delivery Property.


 




    	 	-19-	 



     


    

 


	Share Termination Delivery Unit:	One Share or, if the Shares have changed into cash or any other property or the right to receive cash or any other property as the result of a Nationalization, Insolvency or Merger Event (any such cash or other property, the “Exchange Property”), a unit consisting of the type and amount of such Exchange Property received by a holder of one Share (without consideration of any requirement to pay cash or other consideration in lieu of fractional amounts of any securities) in such Nationalization, Insolvency or Merger Event, as determined by the Calculation Agent.
	 	 
	Failure to Deliver:	Applicable
	 	 
	Other applicable provisions:	If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9 and 9.11 (as modified above) of the Equity Definitions and the provisions set forth opposite the caption “Representation and Agreement” in Section 2 will be applicable, except that all references in such provisions to “Physically-settled” shall be read as references to “Share Termination Settled” and all references to “Shares” shall be read as references to “Share Termination Delivery Units”.  “Share Termination Settled” in relation to the Transaction means that the Share Termination Alternative is applicable to the Transaction.


 


		(m)	Waiver of Jury Trial. Each party waives, to the fullest extent permitted by applicable
law, any right it may have to a trial by jury in respect of any suit, action or proceeding relating to the Transaction. Each party
(i) certifies that no representative, agent or attorney of either party has represented, expressly or otherwise, that such other
party would not, in the event of such a suit, action or proceeding, seek to enforce the foregoing waiver and (ii) acknowledges
that it and the other party have been induced to enter into the Transaction, as applicable, by, among other things, the mutual
waivers and certifications provided herein.



 


		(n)	Registration. Counterparty hereby agrees that if, in the good faith reasonable judgment
of Dealer, the Shares (“Hedge Shares”) acquired by Dealer for the purpose of hedging its obligations pursuant
to the Transaction cannot be sold in the public market by Dealer without registration under the Securities Act, Counterparty shall,
at its election, either (i) in order to allow Dealer to sell the Hedge Shares in a registered offering, make available to Dealer
an effective registration statement under the Securities Act and enter into an agreement, in form and substance satisfactory to
Dealer, substantially in the form of an underwriting agreement for a registered secondary offering; provided, however,
that if Dealer, in its sole reasonable discretion, is not satisfied with access to due diligence materials, the results of its
due diligence investigation, or the procedures and documentation for the registered offering referred to above, then clause (ii)
or clause (iii) of this paragraph shall apply at the election of Counterparty, (ii) in order to allow Dealer to sell the Hedge
Shares in a private placement, enter into a private placement agreement substantially similar to private placement purchase agreements
customary for private placements of equity securities, in form and substance satisfactory to Dealer (in which case, the Calculation
Agent shall make any adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate
Dealer for any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement),
or (iii) purchase the Hedge Shares from Dealer at the Relevant Price on such Exchange Business Days, and in the amounts, requested
by Dealer.



 




    	 	-20-	 



     


    

 


		(o)	Tax Disclosure. Effective from the date of commencement of discussions concerning
the Transaction, Counterparty and each of its employees, representatives, or other agents may disclose to any and all persons,
without limitation of any kind, the tax treatment and tax structure of the Transaction and all materials of any kind (including
opinions or other tax analyses) that are provided to Counterparty relating to such tax treatment and tax structure.



 


		(p)	Right to Extend. Dealer may postpone or add, in whole or in part, any Valid Day or
Valid Days during the Settlement Averaging Period or any other date of valuation, payment or delivery by Dealer, with respect to
some or all of the Options hereunder, if Dealer reasonably determines, in its discretion, that such action is reasonably necessary
or appropriate to preserve Dealer’s hedging or hedge unwind activity hereunder in light of existing liquidity conditions
or to enable Dealer to effect purchases of Shares in connection with its hedging, hedge unwind or settlement activity hereunder

legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to Dealer.



 


		(q)	Status of Claims in Bankruptcy.  Dealer acknowledges and agrees that this
Confirmation is not intended to convey to Dealer rights against Counterparty with respect to the Transaction that are senior to

that nothing herein shall limit or shall be deemed to limit Dealer’s right to pursue remedies in the event of a breach by
Counterparty of its obligations and agreements with respect to the Transaction; provided, further, that nothing herein
shall limit or shall be deemed to limit Dealer’s rights in respect of any transactions other than the Transaction.

each payment and delivery of cash, securities or other property hereunder to constitute a “margin payment” or “settlement
payment” and a “transfer” as defined in the Bankruptcy Code.



 


		(s)	Notice of Certain Other Events. Counterparty covenants and agrees that:



 


		(i)	promptly following the public announcement of the results of any election by the holders of Shares
with respect to the consideration due upon consummation of any Merger Event, Counterparty shall give Dealer written notice of (x)
the weighted average of the types and amounts of consideration that holders of Shares have elected to receive upon consummation
of such Merger Event or (y) if no holders of Shares affirmatively make such election, the types and amounts of consideration actually
received by holders of Shares (the date of such notification, the “Consideration Notification Date”); provided
that in no event shall the Consideration Notification Date be later than the date on which such Merger Event is consummated; and



 


		(ii)	promptly following any adjustment to the Convertible Notes in connection with any Potential Adjustment
Event, Merger Event or Tender Offer, Counterparty shall give Dealer written notice of the details of such adjustment.



 


		(t)	Wall Street Transparency and Accountability Act. In connection with Section 739 of

limit or otherwise impair either party’s otherwise applicable rights to terminate, renegotiate, modify, amend or supplement
this Confirmation or the Agreement, as applicable, arising from a termination event, force majeure, illegality, increased costs,

		(u)	Agreements and Acknowledgements Regarding Hedging. Counterparty understands, acknowledges
and agrees that: (A) at any time on and prior to the Expiration Date, Dealer and its affiliates may buy or sell Shares or other
securities or buy or sell options or futures contracts or enter into swaps or other derivative securities in order to adjust its
hedge position with respect to the Transaction; (B) Dealer and its affiliates also may be active in the market for Shares other
than in connection with hedging activities in relation to the Transaction; (C) Dealer shall make its own determination as to whether,

that it deems appropriate to hedge its price and market risk with respect to the Relevant Prices; and (D) any market activities
of Dealer and its affiliates with respect to Shares may affect the market price and volatility of Shares, as well as the Relevant
Prices, each in a manner that may be adverse to Counterparty.

with the Transaction at the then prevailing market price. Each of Dealer and Counterparty represents and acknowledges to the other

shall be deemed fully and finally discharged.

an Early Termination Date occurs or is designated with respect to the Transaction as a result of a Termination Event or an Event
of Default (other than an Event of Default arising under Section 5(a)(ii) or 5(a)(iv) of the Agreement) and, as a result, Counterparty
owes to Dealer an amount calculated under Section 6(e) of the Agreement, or (ii) Counterparty owes to Dealer, pursuant to Section

as Section 871(m) of the Code by United States P.L. 111-226, (ii) Section 871(m) of the Code after Section 871(1) of the Code (as
