Re: [Base] [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 [______] ("Dealer") and ServiceSource International,
Inc. ("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
August [__], 2013, (the "Offering Memorandum") relating to the [_]% Convertible Senior Notes due 2018 (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 [_____] [(as increased by up to an aggregate principal amount of USD [___] if and to the extent that the
Representative (as defined herein) exercises its option to purchase additional Convertible Notes pursuant to the Purchase Agreement
(as defined herein))]1 pursuant to an Indenture to be dated August [___], 2013 (the "Indenture"), between
Counterparty and Wells Fargo Bank, N.A., as trustee (the "Trustee").  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, in each case,
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 [draft of the Indenture last reviewed by Dealer and Counterparty as of the date of this Confirmation, and if any such section
numbers are changed in the Indenture as executed, the parties will amend this Confirmation in good faith to preserve the intent of the
parties]2 [Indenture as executed]3.  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 following such date, any such amendment (other than any
amendment pursuant to Section 10.01(j) of the Indenture that, as determined by the Calculation Agent, conforms the Indenture to the
description of the Convertible Notes in the Offering Memorandum) will be disregarded for purposes of this Confirmation unless the
parties agree otherwise in writing.4

	Potential Adjustment Events:

	
Notwithstanding Section 11.2(e) of the Equity Definitions, a "Potential Adjustment
Event" means an occurrence of any event or condition, as set forth in any Dilution Adjustment Provision, that would result in an
adjustment under the Indenture to the "Conversion Rate" or the composition of a "unit of Reference Property" or
to any "Last Reported Sale Price," "Daily VWAP," "Daily Conversion Value" or "Daily
Settlement Amount" (each as defined in the Indenture).  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
Section 14.04(c) of the Indenture or the fourth sentence of Section 14.04(d) of the Indenture).

Definitions, upon any Potential Adjustment Event, the Calculation Agent shall make a corresponding adjustment to any one or more of
the Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the
Transaction; provided that, notwithstanding the foregoing, if the Calculation Agent in good faith disagrees with any adjustment to
the Convertible Notes that involves an exercise of discretion by Counterparty or its board of directors (including, without limitation,
pursuant to Section 14.05 of the Indenture or in connection with any proportional adjustment or the determination of the fair value of any
securities, property, rights or other assets) and determines that such adjustment was materially inaccurate or based on materially
inaccurate inputs, then in each such case, the Calculation Agent will determine the adjustment to be made to any one or more of the
Strike Price, Number of Options, Option Entitlement and any other variable relevant to the exercise, settlement or payment for the
Transaction in a commercially reasonable manner; provided further that, notwithstanding the foregoing, if any Potential
Adjustment Event occurs during the Settlement Averaging Period but no adjustment was made to any Convertible Note under the
Indenture because the relevant Holder (as such term is defined in the Indenture) was deemed to be a record owner of the underlying
Shares on the related Conversion Date, then the Calculation Agent shall make an adjustment, as determined by it, to the terms hereof
in order to account for such Potential Adjustment Event.

	Dilution Adjustment Provisions:

	
Sections 14.04(a), 14.04(b), 14.04(c), 14.04(d) and 14.04(e) and Section 14.05 of the

	Tender Offers:

	
Notwithstanding Section 12.2 and Section 12.3 of the Equity Definitions, upon the occurrence
of a Merger Event or a Tender Offer, the Calculation Agent shall make a corresponding adjustment in respect of any adjustment under
the Indenture to any one or more of the nature of the Shares (in the case of a Merger Event), Strike Price, Number of Options, Option
Entitlement and any other variable relevant to the exercise, settlement or payment for the Transaction; provided,
however, that such adjustment shall be made without regard to any adjustment to the Conversion Rate pursuant to any Excluded
Provision; provided further that if, with respect to a Merger Event or a Tender Offer, (i) the consideration for the Shares includes
(or, at the option of a holder of Shares, may include) shares of an entity or person that is not a corporation or is not organized under the
laws of the United States, any State thereof or the District of Columbia or (ii) Counterparty to the Transaction following such Merger
Event or Tender Offer will not be a corporation or will not be the Issuer following such Merger Event or Tender Offer, then Dealer, in its
sole discretion, may elect for Cancellation and Payment (Calculation Agent Determination) to apply.

	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.

	
Additional Disruption Events:
	 
	Change in Law:

	
Applicable; provided that (i) Section 12.9(a)(ii) of the Equity Definitions is hereby

	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 August [__], 2013, between Counterparty and Morgan Stanley
& Co. LLC, as representative of the Initial Purchasers party thereto (the "Representative"), 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:  

	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.

	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.

	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.

	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.

	Counterparty is an "eligible contract participant" (as such term is defined in Section 1a(18) of
the Commodity Exchange Act, as amended).

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

                                              14

	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.

	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.

	Other Provisions.

	Opinions.  Counterparty shall deliver to Dealer an
opinion of counsel, dated as of the Trade Date, with respect to the due incorporation, existence and good standing of Counterparty in
Delaware, the due authorization, execution and delivery of this Confirmation, and, in respect of the execution, delivery and performance
of this Confirmation, the absence of any conflict with or breach of any material agreement required to be filed as an exhibit to
Counterparty's Annual Report on Form 10-K, Counterparty's certificate of incorporation or Counterparty's by-laws.  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.

	Repurchase Notices.  Counterparty shall, on any day on
which Counterparty effects any repurchase of Shares or consummates or otherwise executes or engages in any transaction or event (a
"Conversion Rate Adjustment Event") that would lead to an increase in the Conversion Rate (as such term is
defined in the Indenture), promptly give Dealer a written notice of such repurchase or Conversion Rate Adjustment Event (a
"Repurchase Notice") on such day if following such repurchase or Conversion Rate Adjustment Event, as the case
may be, the number of outstanding Shares as determined on such day is (i) less than [__]10 million (in the case of the first such notice) or
(ii) thereafter more than [__]11 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
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, 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 and documented legal or other expenses incurred 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

__________________

10 To be the number of Shares outstanding that would cause Dealer's current position in the shares
underlying the Transaction (including the number of Shares underlying any additional transaction if the greenshoe is
exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by 0.5%.

   11 To be the number of Shares that, if repurchased, would cause Dealer's current position in the shares
underlying the Transaction (including the number of Shares underlying any additional transaction if the greenshoe is
exercised in full, and any Shares under pre-existing call option transactions with Counterparty) to increase by a further
0.5% from the threshold for the first Repurchase Notice.

                                             15

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 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 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.

	Regulation M.  Counterparty is not on the Trade Date engaged in a distribution, as such
term is used in Regulation M under 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.

	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 manipulate the price of the
Shares (or any security convertible into or exchangeable for the Shares) in violation of the Exchange Act.

	Transfer or Assignment.  

	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:

	With respect to any Transfer Options, Counterparty shall not be released from its notice and indemnification
obligations pursuant to Section 7(b) or any obligations under Section 7(m) or 7(r) of this Confirmation;

	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);

	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 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;

                                            16

	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;

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

	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

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

	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 rating for its long term, unsecured and unsubordinated indebtedness
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, by Dealer or
[______], or (B) to any other third party with a rating for its long term, unsecured and unsubordinated indebtedness equal to or better
than the lesser of (1) the credit rating of Dealer at the time of the transfer and (2) BBB- by Standard and Poor's Rating Group, Inc. or its
successor ("S&P"), or Baa3 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; provided that, solely as a result of such a transfer, Counterparty shall not receive any payment from
which an amount is required to be deducted or withheld for or on account of a Tax with respect to which no additional amount is
required to the paid by the transferee under Section 2(d)(i)(4) of the Agreement (other than by reason of Section 2(d)(i)(4)(A) or (B)
thereof).  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.  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 each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the
Exchange Act and rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the
Exchange Act and rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding.  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

                                            17

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.

	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 only to the extent of any such
performance.

	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:

	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;

	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

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

	Role of Agent.  [Insert relevant Dealer agency language.]

                                            18

	Additional Termination Events.  

	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,
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.

	Notwithstanding anything to the contrary in this Confirmation, the receipt by
Dealer from Counterparty, within the applicable time period set forth opposite "Notice of Exercise" in Section 2, of any
Notice of Exercise in respect of Options that relate to Convertible Notes as to which additional Shares would be added to the
Conversion Rate (as defined in the Indenture) pursuant to Section 14.03 of the Indenture in connection with a "Make-Whole
Fundamental Change" (as defined in the Indenture) shall constitute an Additional Termination Event as provided in this Section
7(h)(ii).  Upon receipt of any such Notice of Exercise, Dealer shall designate an Exchange Business Day following such
Additional Termination Event (which Exchange Business Day shall in no event be earlier than the related settlement date for such
Convertible Notes) as an Early Termination Date with respect to the portion of the Transaction corresponding to a number of Options
(the "Make-Whole Conversion Options") equal to the lesser of (A) the number of such Options specified in such
Notice of Exercise [minus the number of "Make-Whole Conversion Options" (as defined in the Base Call Option
Confirmation), if any, that relate to such Convertible Notes]12 and (B) the Number of Options as of the date Dealer designates such Early
Termination Date and, as of such date, the Number of Options shall be reduced by the number of Make-Whole Conversion
Options.  Any payment hereunder with respect to such termination (the "Make-Whole Unwind Payment")
shall be calculated 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 Make-Whole Conversion
Options, (2) Counterparty were the sole Affected Party with respect to such Additional Termination Event and (3) the terminated portion
of the Transaction were the sole Affected Transaction (and, for the avoidance of doubt, in determining the amount payable pursuant to
Section 6 of the Agreement, the Calculation Agent shall not take into account any adjustments to the Option Entitlement that result from
corresponding adjustments to the Conversion Rate (as defined in the Indenture) pursuant to Section 14.03 of the Indenture);
provided that the amount of cash deliverable in respect of such early termination by Dealer to Counterparty shall not be greater
than the product of (x) the Applicable Percentage and (y) the excess of (I) (1) the number of Make-Whole Conversion Options
multiplied by (2) the Conversion Rate (as defined in the Indenture, and after taking into account any applicable adjustments to
the Conversion Rate pursuant to Section 14.03 of the Indenture) multiplied by (3) a market price per Share determined by the
Calculation Agent  in a commercially reasonable manner over (II) the aggregate principal amount of such Convertible Notes, as
determined by the Calculation Agent in a commercially reasonable manner.  Counterparty may irrevocably elect in the relevant
Notice of Exercise to receive any Make-Whole Unwind Payment in Shares, in which case, in lieu of making such Make-Whole Unwind
Payment as set forth above, Dealer shall deliver to Counterparty, within a commercially reasonable period of time after such
designation as determined by Dealer (taking into account existing liquidity conditions and Dealer's hedging and hedge unwind activity or
settlement activity in connection with such delivery) a number of Shares equal to (A) such Make-Whole Unwind Payment, divided
by (B) a price per Share determined by the Calculation Agent in good faith and in a commercially reasonable manner;
provided that Counterparty may elect to receive a Make-Whole Unwind Payment in Shares only if Counterparty represents and
warrants to Dealer in writing on the date of such election that Counterparty is not in possession of any material non-public information
regarding Counterparty or the Shares.

	Amendments to Equity Definitions.  

	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) at Dealer's option, 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."

	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.

	No Setoff.  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.

	Alternative Calculations and Payment on Early Termination and on
Certain  Extraordinary Events.  If in respect of the Transaction, an amount is payable by Dealer to Counterparty (i) pursuant to
Section 12.7 or Section 12.9 of the Equity Definitions or (ii) pursuant to Section 6(d)(ii) of the Agreement (any such amount, a
"Payment Obligation"), 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, the Tender Offer Date, the Announcement Date (in the
case of Nationalization, Insolvency or Delisting), the 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 6(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 (the
"Share Termination Payment Date"), 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.

                                            20

	
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 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 Unit Price the Calculation Agent may consider the purchase price paid in connection with the purchase of Share
Termination Delivery Property.

	
Share Termination Delivery Unit: 
	
One Share or, if a Nationalization, Insolvency or Merger Event has occurred and a
corresponding adjustment to the Transaction has been made, a unit consisting of the type and amount of such 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 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.

	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.

	Registration.  Counterparty hereby agrees that if, in the good
faith reasonable judgment of Dealer based on the advice of counsel, 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
customary form and substance reasonably satisfactory to Dealer, substantially in the form of an underwriting agreement for a registered
secondary offering of equity securities of companies comparable in size, maturity and line of business; 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 of companies comparable in size, maturity and line of business, in customary form and
substance reasonably satisfactory to Dealer (in which case, the Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary,

                                            21

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.

	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.

	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
transactions in Shares in connection with its hedging, hedge unwind or settlement activity hereunder in a manner that would, if Dealer
were Counterparty or an affiliated purchaser of Counterparty, be in compliance with applicable legal, regulatory or self-regulatory
requirements, or with related policies and procedures applicable to Dealer; provided that in no event shall Dealer have the right
to so postpone or add any Valid Day(s) or any such other date beyond the 50th Valid Day immediately following the last Valid Day of
the relevant Settlement Averaging Period (determined without regard to this Section 9(o)).

	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 the
claims of common stockholders of Counterparty in any United States bankruptcy proceedings of Counterparty; provided 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.

	Securities Contract; Swap Agreement.  The parties hereto intend for (i) the Transaction to
be a "securities contract" and a "swap agreement" as defined in the Bankruptcy Code (Title 11 of the United
States Code) (the "Bankruptcy Code"), and the parties hereto to be entitled to the protections afforded by, among
other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party's right to liquidate the
Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the
other party to constitute a "contractual right" as described in the Bankruptcy Code, and (iii) 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.

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

	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 the types
and amounts of consideration that holders of Shares have elected to receive upon consummation of such Merger Event (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 

	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.

                                            22

	Wall Street Transparency and Accountability Act.  In connection with Section 739 of the
Wall Street Transparency and Accountability Act of 2010 ("WSTAA"), the parties hereby agree that neither the
enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA,
shall 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, regulatory
change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited
to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as
defined in the Agreement)).

	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, when or in
what manner any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner 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.

	Early Unwind. In the event the sale of the ["Firm]13
["Additional]14 Securities" (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers for any
reason, or Counterparty fails to deliver to Dealer opinions of counsel as required pursuant to Section 7(a), in each case by 5:00 p.m.
(New York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or
such later date, the "Early Unwind Date"), the Transaction shall automatically terminate (the "Early
Unwind") on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and
Counterparty under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other
party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising
out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date; provided that
Counterparty shall elect (i) to purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its
affiliates in connection with the Transaction (the "Existing Hedge Shares") at the aggregate price Dealer or any
such affiliate paid for such Shares (the "Early Unwind Amount") or (ii) for Dealer to sell the Existing Hedge Shares
during a period (the "Unwind Resale Period") commencing on the Exchange Business Day following the Early
Unwind Date and ending on the Exchange Business Day on which Dealer completes the sale of all Existing Hedge Shares (and any
Make-whole Unwind Shares (as defined below), if applicable).  If the Early Unwind Amount exceeds the realized net proceeds from the
sale by Dealer of the Existing Hedge Shares, Counterparty shall transfer to Dealer by the open of the regular trading session on the
Exchange on the Exchange Trading Day immediately following the last day of the Unwind Resale Period the amount of such excess
(the "Additional Unwind Amount"), at Counterparty's election, in cash or in a number of Shares ("Make-whole
Unwind Shares") in an amount that, based on the estimated per Share resale value of such Make-whole Unwind
Shares (as determined by the Calculation Agent in a commercially reasonable manner), has a value equal to the Additional Unwind
Amount. The Unwind Resale Period shall continue to enable the sale of the Make-whole Unwind Shares and this provision shall be
applied successively until the Additional Unwind Amount is equal to zero. In connection with the sale of any Existing Hedge Shares and
any Make-whole Unwind Shares pursuant to this Section 7(u), Counterparty shall, at its election, either (i) in order to allow Dealer to sell
such Existing Hedge Shares and such Make-whole Unwind Shares in a registered offering, make available to Dealer an effective
registration statement under the Securities Act and enter into an agreement, in customary form and substance reasonably satisfactory
to Dealer, substantially in the form of an underwriting agreement for a

registered secondary offering of equity securities of companies
comparable in size, maturity and line of business (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) of this sentence shall apply) or (ii) in order to allow Dealer to sell such
Existing Hedge Shares and such Make-whole Unwind 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 of companies
comparable in size, maturity and line of business, in customary form and substance reasonably satisfactory to Dealer (it being
understood and agreed that the sale price for such Existing Hedge Shares and such Make-whole Unwind Shares pursuant to this
clause (ii) shall reflect a commercially reasonable liquidity discount from the public market price of the Shares). In no event shall
Company deliver a number of Shares pursuant to this Section 7(u) greater than two times the aggregate number of Shares underlying
the Number of Options. Each of Dealer and Counterparty represents and acknowledges to the other that, subject to the proviso
included in this Section 7(u), upon an Early Unwind, all obligations with respect to the Transaction shall be deemed fully and finally
discharged.

	Payment by Counterparty. In the event that, following payment of the Premium, (i) 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 12.7 or Section
12.9 of the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be
zero.

 

 

                                            24

Please confirm that the foregoing correctly sets forth the terms of the agreement between Dealer
and Counterparty with respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions (the "Equity

Dealer and Company as to the terms of the Transaction to which this Confirmation relates.  This Confirmation shall supplement, form a
part of, and be subject to an agreement in the form of the 2002 ISDA Master Agreement (the "Agreement") as if

	Expiration Dates: 

	
Each Scheduled Trading Day during the period from, and including, the First Expiration Date
to, but excluding, the 100th Scheduled Trading Day following the First Expiration Date shall be an "Expiration Date" for a
number of Warrants equal to the Daily Number of Warrants on such date; provided that, notwithstanding anything to the contrary
in the Equity Definitions, if any such date is a Disrupted Day, the Calculation Agent shall (i) make reasonable adjustments, if applicable,
to the Daily Number of Warrants or shall reduce such Daily Number of Warrants to zero for which such day shall be an Expiration Date
and shall designate a Scheduled Trading Day or a number of Scheduled Trading Days as the Expiration Date(s) for the remaining Daily
Number of Warrants or a portion thereof for the originally scheduled Expiration Date and (ii) if the Daily Number of Warrants for such

such Disrupted Day taking into account the nature and duration of such Market Disruption Event on such day; and provided
further that if such Expiration Date has not occurred pursuant to this clause as of the eighth Scheduled Trading Day following the
last scheduled Expiration Date under the Transaction, the Calculation Agent shall have the right to declare such Scheduled Trading
Day to be the final Expiration Date and the Calculation Agent shall determine its good faith estimate of the fair market value for the
Shares as of the Valuation Time on that eighth Scheduled Trading Day or on any subsequent Scheduled Trading Day, as the
Calculation Agent shall determine using commercially reasonable means.  Any Scheduled Trading Day on which, as of the date hereof,
the Exchange is scheduled to close prior to its normal close of trading shall be deemed not to be a Scheduled Trading Day; if a closure
of the Exchange prior to its normal close of trading on any Scheduled Trading Day is scheduled following the date hereof, then such
Scheduled Trading Day shall be deemed to be a Disrupted Day in full.

	First Expiration Date:

Scheduled Trading Day), subject to "Market Disruption Event" below.

	Daily Number of Warrants:

whole number, subject to adjustment pursuant to the provisos to "Expiration Dates".

	Automatic Exercise: 

	
Applicable; and means that for each Expiration Date, a number of Warrants equal to the Daily
Number of Warrants for such Expiration Date will be deemed to be automatically exercised at the Expiration Time on such Expiration
Date.

                                             3

Section 6.3(a) of the Equity Definitions is hereby amended by replacing clauses (ii) and (iii) in
their entirety with "(ii) an Exchange Disruption, (iii) an Early Closure or (iv) a Regulatory Disruption; in each case that the
Calculation Agent determines is material."

	 	
Section 6.3(d) of the Equity Definitions is hereby amended by deleting the remainder of the
provision following the words "Scheduled Closing Time" in the fourth line thereof.

	Regulatory Disruption:

	
Any event that Dealer, in its discretion, determines makes it appropriate with regard to any
legal, regulatory or self-regulatory requirements or related policies and procedures, for Dealer to refrain from or decrease any market
activity in connection with the Transaction. Dealer shall notify Company as soon as reasonably practicable that a Regulatory Disruption
has occurred and the Expiration Dates affected by it.

	
Valuation Terms.
	 
	Valuation Time:

	
Scheduled Closing Time; provided that if the principal trading session is extended, the
Calculation Agent shall determine the Valuation Time in its reasonable discretion.

	Valuation Date:

	
Each Exercise Date. 

	
Settlement Terms.
	 
	Settlement Method Election:

	
Applicable; provided that (i) references to "Physical Settlement" in
Section 7.1 of the Equity Definitions shall be replaced by references to "Net Share Settlement"; (ii) Company may
elect Cash Settlement only if Company represents and warrants to Dealer in writing on the date of such election that
(A) Company is not in possession of any material non-public information regarding Company or the Shares, (B) Company
is electing Cash Settlement in good faith and not as part of a plan or scheme to evade compliance with the federal securities laws, and
(C) the assets of Company at their fair valuation exceed the liabilities of Company (including contingent liabilities), and Company
has the ability to pay its debts and obligations as such debts mature; and (iii) the same election of settlement method shall apply
to all Expiration Dates hereunder.

	Electing Party:

	
Company

	Settlement Method Election Date:

	
The third Scheduled Trading Day immediately preceding the scheduled First Expiration
Date.

	Default Settlement Method:

	
Net Share Settlement

                                             4

	Net Share Settlement:

	
If Net Share Settlement is applicable, then on the relevant Settlement Date, Company shall
deliver to Dealer a number of Shares equal to the Share Delivery Quantity for such Settlement Date to the account specified herein free
of payment through the Clearance System and Company shall pay to Dealer any Fractional Share Amount.  Dealer shall be treated as
the holder of record of such Shares at the time of delivery of such Shares or, if earlier, at 5:00 p.m. (New York City time) on such
Settlement Date.

	Cash Settlement:

	
If Cash Settlement is applicable, then on the relevant Settlement Date, Company shall pay to
Dealer an amount of cash in USD equal to the Net Share Settlement Amount for such Settlement Date.

	Share Delivery Quantity:

	
For any Settlement Date, a number of Shares, as calculated by the Calculation Agent, equal to
the Net Share Settlement Amount for such Settlement Date divided by the Settlement Price on the Valuation Date for such
Settlement Date, rounded down to the nearest whole number.

	 	
Section 9.7 of the Equity Definitions is hereby amended by (i) replacing the words
"Number of Shares to be Delivered" with the words "Share Delivery Quantity" in the second and third lines
thereof and (ii) deleting the parenthetical in clause (a) thereof.

	Net Share Settlement Amount:

	
For any Settlement Date, an amount equal to the product of (i) the number of Warrants
exercised or deemed exercised on the relevant Exercise Date, (ii) the Strike Price Differential for the relevant Valuation Date and
(iii) the Warrant Entitlement. 

	Settlement Price:

	
For any Valuation Date, the per Share volume-weighted average price as displayed under the
heading "Bloomberg VWAP" on Bloomberg page "SREV <equity> AQR" (or any successor thereto) in
respect of the period from the scheduled opening time of the Exchange to the Scheduled Closing Time on such Valuation Date (or if
such volume-weighted average price is unavailable, the market value of one Share on such Valuation Date, as determined by the
Calculation Agent). Notwithstanding the foregoing, if (i) any Expiration Date is a Disrupted Day and (ii) the Calculation Agent determines
that such Expiration Date shall be an Expiration Date for fewer than the otherwise applicable Daily Number of Warrants, as described
above, then the Settlement Price for the relevant Valuation Date shall be the volume-weighted average price per Share on such
Valuation Date on the Exchange, as determined by the Calculation Agent based on such sources as it deems appropriate using a
volume-weighted methodology, for the portion of such Valuation Date for which the Calculation Agent determines in good faith and in a
commercially reasonable manner there is no Market Disruption Event.

	Settlement Dates:

	
As determined pursuant to Section 9.4 of the Equity Definitions, subject to Section 9(k)(i)
hereof; provided that Section 9.4 of the Equity Definitions is hereby amended by (i) inserting the words "or cash"
immediately following the word "Shares" in the first line thereof and (ii) inserting the words "for the Shares"
immediately following the words "Settlement Cycle" in the second line thereof.

                                             5

	Other Applicable Provisions: 

	
If Net Share Settlement is applicable, the provisions of Sections 9.1(c), 9.8, 9.9, 9.11 and 9.12
of the Equity Definitions will be applicable; except that all references in such provisions to "Physically-settled" shall be read
as references to "Net Share Settled."  "Net Share Settled" in relation to any Warrant means that Net Share
Settlement is applicable to that Warrant.

	Representation and Agreement:

	
Notwithstanding Section 9.11 of the Equity Definitions, the parties acknowledge that any
Shares delivered to Dealer may be, upon delivery, subject to restrictions and limitations arising from Company's status as issuer of the
Shares under applicable securities laws.

	
3.  Additional Terms applicable to the Transaction.
	 
	Adjustments applicable to the Transaction:

	 
	Method of Adjustment: 

	
Calculation Agent Adjustment; provided that the parties hereto agree that open market
Share repurchases at prevailing market prices shall not be considered Potential Adjustment Events.  For the avoidance of doubt, in
making any adjustments under the Equity Definitions, the Calculation Agent may make adjustments, if any, to any one or more of the
Strike Price, the Number of Warrants, the Daily Number of Warrants and the Warrant Entitlement.  Notwithstanding the foregoing, any
cash dividends or distributions on the Shares, whether or not extraordinary, shall be governed by Section 9(f) of this Confirmation in lieu
of Article 10 or Section 11.2(c) of the Equity Definitions.

	Extraordinary Events applicable to the Transaction:

	 
	New Shares:

	
Section 12.1(i) of the Equity Definitions is hereby amended (a) by deleting the text in clause (i)
thereof in its entirety (including the word "and" following clause (i)) and replacing it with the phrase "publicly quoted,
traded or listed (or whose related depositary receipts are publicly quoted, traded or listed) on any of the New York Stock Exchange, The
NASDAQ Global Select Market or The NASDAQ Global Market (or their respective successors)" and (b) by inserting immediately
prior to the period the phrase "and (iii) of an entity or person that is a corporation organized under the laws of the United States,
any State thereof or the District of Columbia that also becomes Company under the Transaction following such Merger Event or Tender
Offer".

	Consequence of Merger Events:

	 
	Merger Event:

	
Applicable; provided that if an event occurs that constitutes both a Merger Event under
Section 12.1(b) of the Equity Definitions and an Additional Termination Event under Section 9(h)(ii)(B) of this Confirmation, Dealer may
elect, in its commercially reasonable judgment, whether the provisions of Section 12.2 of the Equity Definitions or Section 9(h)(ii)(B) will
apply.

	Tender Offer:

	
Applicable; provided that if an event occurs that constitutes both a Tender Offer under
Section 12.1(d) of the Equity Definitions and Additional Termination Event under Section 9(h)(ii)(A) of this Confirmation, Dealer may
elect, in its commercially reasonable judgment, whether the provisions of Section 12.3 of the Equity Definitions or Section 9(h)(ii)(A) will
apply; provided further that for purposes of Section 12.3(d) of the Equity Definitions, only in the case of a self-tender by
Company references in the definition of Tender Offer under the Equity Definitions to 10% shall be replaced with 20%.

	Announcement Event:

	
If an Announcement Date occurs in respect of a Merger Event (for the avoidance of doubt,
determined without regard to the language in the definition of "Merger Event" following the definition of "Reverse
Merger" therein) or Tender Offer (such occurrence, an "Announcement Event"), then on the earliest of the
Expiration Date, Early Termination Date or other date of cancellation (the "Announcement Event Adjustment Date")
in respect of each Warrant, the Calculation Agent will determine the economic effect on such Warrant of the Announcement Event
(regardless of whether the Announcement Event actually results in a Merger Event or Tender Offer, and taking into account such
factors as the Calculation Agent may determine, including, without limitation, changes in volatility, expected dividends, stock loan rate
or liquidity relevant to the Shares or the Transaction whether prior to or after the Announcement Event or for any period of time such
changes are in effect, including, without limitation, if applicable, the period from the Announcement Event to the relevant Announcement
Event Adjustment Date).  If the Calculation Agent determines that such economic effect on any Warrant is material, then on the
Announcement Event Adjustment Date for such Warrant, the Calculation Agent may make such adjustment to the exercise, settlement,
payment or any other terms of such Warrant as the Calculation Agent determines appropriate to account for such economic effect for
the relevant period, which adjustment shall be effective immediately prior to the exercise, termination or cancellation of such Warrant,
as the case may be.

	Representations and Warranties of Company.

Each of the representations and warranties of Company set forth in Section 1 of the Purchase Agreement
(the "Purchase Agreement"), dated as of August [__], 2013, between Company and Morgan Stanley & Co.
LLC, as representative of the Initial Purchasers party thereto, are true and correct and are hereby deemed to be repeated to Dealer as
if set forth herein.  Company hereby further represents and warrants to Dealer on the date hereof, on and as of the Premium Payment
Date and, in the case of the representations in Section 8(d), at all times until termination of the Transaction, that:

	Company 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 Company's part; and this Confirmation has been duly and validly executed and delivered by
Company and constitutes its valid and binding obligation, enforceable against Company 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.

	Neither the execution and delivery of this Confirmation nor the incurrence or performance of obligations of
Company hereunder will (i) conflict with or result in a breach of (A) the certificate of incorporation or by-laws (or any equivalent
documents) of Company, (B) any applicable law or regulation, (C) any order, writ, injunction or decree of any court or governmental
authority or agency, or (D) any agreement or instrument to which Company or any of its subsidiaries is a party or by which Company or
any of its subsidiaries is bound or to which Company or any of its subsidiaries is subject, or (ii) constitute a default under, or result in the
creation of any lien under, any agreement or instrument referred to in clause (i)(D) of this Section 8(b).

	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 Company of this Confirmation, except such as have been
obtained or made and such as may be required under the Securities Act of 1933, as amended (the "Securities Act")
or state securities laws.

	A number of Shares equal to the Maximum Number of Shares (as defined
below) (the "Warrant Shares") have been reserved for issuance by all required corporate action of Company.  The
Warrant Shares have been duly authorized and, when delivered against payment therefor (which may include Net Share Settlement in
lieu of cash) and otherwise as contemplated by the terms of the Warrants following the exercise of the Warrants in accordance with the
terms and conditions of the Warrants, will be validly issued, fully-paid and non-assessable, and the issuance of the Warrant Shares will
not be subject to any preemptive or similar rights.

	Company 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.

	Company is an "eligible contract participant" (as such term is defined in Section 1a(18) of the
Commodity Exchange Act, as amended).

	Company and each of its affiliates is not, on the date hereof, in possession of any material non-public
information with respect to Company or the Shares.

	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.

                                            11

	Company (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.

	Other Provisions.

	Opinions.  Company shall deliver to Dealer an opinion
of counsel, dated as of the Trade Date, with respect to the due incorporation, existence and good standing of Company in Delaware,
the due authorization, execution and delivery of this Confirmation, and, in respect of the execution, delivery and performance of this
Confirmation, the absence of any conflict with or breach of any material agreement required to be filed as an exhibit to Company's
Annual Report on Form 10-K, Company's certificate of incorporation or Company's by-laws.  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.

	Repurchase Notices.  Company shall, on any day on which Company 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 on such day, subject to any adjustments provided herein, is (i) less
than [___]3 million (in the case of the first such notice) or (ii) thereafter more than [___]4 million less than the number of Shares included
in the immediately preceding Repurchase Notice.  Company 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 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 actually may
become subject to, as a result of Company'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 and
documented legal or other expenses incurred 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, such Indemnified Person shall promptly
notify Company in writing, and Company, upon request of the Indemnified Person, shall retain counsel reasonably satisfactory to the
Indemnified Person to represent the Indemnified Person and any others Company may designate in such proceeding and shall pay the
reasonable fees and expenses of such counsel related to such proceeding.  Company shall not be liable for any settlement of any
proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, Company
agrees to indemnify any Indemnified Person from and against any loss or liability by reason of such settlement or judgment.  Company
shall not, without the prior written consent of the Indemnified Person, effect any settlement of any pending or threatened proceeding in
respect of which any Indemnified Person is 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

__________________

3  To be the number of Shares outstanding that would cause Dealer's current position in the Warrants
(including the number of Warrants if the greenshoe is exercised in full, and any Shares under pre-existing warrant
transactions with Company) to increase by 0.5%.

   4  To be the number of Shares outstanding that would cause Dealer's current position in the Warrants
(including the number of Warrants if the greenshoe is exercised in full, and any Shares under pre-existing warrant
transactions with Company) to increase by a further 0.5% from the threshold for the first Repurchase Notice.

                                            12

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 Company under such paragraph, 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 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.

	Regulation M.  Company 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 Company, other than a distribution meeting the requirements of the exception set forth in Rules 101(b)(10) and 102(b)(7)
of Regulation M.  Company shall not, until the second Scheduled Trading Day immediately following the Effective Date, engage in any
such distribution.

	No Manipulation.  Company 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 manipulate the price of the
Shares (or any security convertible into or exchangeable for the Shares) in violation of the Exchange Act.

	Transfer or Assignment.  Company may not transfer any of its rights or obligations under
the Transaction without the prior written consent of Dealer.  Dealer may, without Company's consent, transfer or assign all or any part
of its rights or obligations under the Transaction to any third party.  If at any time at which (A) the Section 16 Percentage exceeds 7.5%,
(B) the Warrant 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, acting in good faith, is
unable after using its commercially reasonable efforts to effect a transfer or assignment of Warrants 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 Terminated Portion, 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 Warrants equal to the number of Warrants underlying the Terminated
Portion, (2) Company 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(j) shall apply to any amount that is payable by
Company to Dealer pursuant to this sentence as if Company were 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 each person subject to aggregation of Shares with Dealer under Section 13 or Section 16 of the Exchange Act and
rules promulgated thereunder directly or indirectly beneficially own (as defined under Section 13 or Section 16 of the Exchange Act and
rules promulgated thereunder) and (B) the denominator of which is the number of Shares outstanding.  The "Warrant 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 Warrants and the Warrant Entitlement and (2) the aggregate number of Shares underlying any other warrants
purchased by Dealer from Company, 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 Company 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

                                            13

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.  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 Company, Dealer may designate any of its affiliates to purchase, sell, receive or deliver such
Shares or other securities, or 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 Company only to the
extent of any such performance. 

	Dividends.  If at any time during the period from and
including the Effective Date, to and including the last Expiration Date, an ex-dividend date for a cash dividend or distribution (whether or
not extraordinary) occurs with respect to the Shares (an "Ex-Dividend Date"), then the Calculation Agent will adjust
any of the Strike Price, Number of Warrants and/or Daily Number of Warrants to preserve the fair value of the Warrants to Dealer after
taking into account such dividend.  

	Role of Agent.   [Insert relevant Dealer agency language]

	Additional Provisions.

	Amendments to the Equity Definitions:

line thereof and (z) deleting the phrase "(provided that no adjustments will be made to account solely for changes in volatility,
expected dividends, stock loan rate or liquidity relative to the relevant Shares)" and replacing it with the phrase "(provided that, solely in the case of Sections 11.2(e)(i), (ii)(A), (iv) and (v), no adjustments will be made to account solely for changes in volatility, expected
dividends, stock loan rate or liquidity relative to the relevant Shares but, for the avoidance of doubt, solely in the case of Sections
11.2(e)(ii)(B) through (D), (iii), (vi) and (vii), adjustments may be made to account solely for changes in volatility, expected dividends,
stock loan rate or liquidity relative to the relevant Shares)."

	Section 11.2(e)(vii) of the Equity Definitions is hereby amended by deleting the words "a diluting or
concentrative" and replacing them with the words "a material"; and adding the phrase "or Warrants" at the
end of the sentence.

	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

specified in Section 5(a)(vii) (1) through (9) of the ISDA Master Agreement with respect to that Issuer."

	Section 12.9(b)(iv) of the Equity Definitions is hereby amended by:

                                            14

(x)deleting (1) subsection (A) in its entirety, (2) the phrase "or (B)" following subsection (A) and
(3) the phrase "in each case" in subsection (B); and

(y)replacing the phrase "neither the Non-Hedging Party nor the Lending Party lends Shares"
with the phrase "such Lending Party does not lend Shares" in the penultimate sentence.

	Section 12.9(b)(v) of the Equity Definitions is hereby
amended by:

(x)adding the word "or" immediately before subsection "(B)" and deleting the comma
at the end of subsection (A); and

(y)(1) deleting subsection (C) in its entirety, (2) deleting the word "or" immediately preceding
subsection (C), (3) deleting the penultimate sentence in its entirety and replacing it with the sentence "The Hedging Party will
determine the Cancellation Amount payable by one party to the other." and (4) deleting clause (X) in the final sentence.

	Notwithstanding anything to the contrary in this Confirmation, upon the
occurrence of one of the following events, with respect to the Transaction, (1) Dealer shall have the right to designate such event an
Additional Termination Event and designate an Early Termination Date pursuant to Section 6(b) of the Agreement, (2) Company shall
be deemed the sole Affected Party with respect to such Additional Termination Event and (3) the Transaction shall be deemed the sole
Affected Transaction (provided that with respect to any Additional Termination Event, Dealer may choose to treat part of the
Transaction as the sole Affected Transaction, in which case the remainder of the Transaction shall continue in full force and
effect):

	A "person" or "group" within the meaning of Section
13(d) of the Exchange Act, other than Company, its subsidiaries and its and their employee benefit plans, files a Schedule TO or any
schedule, form or report under the Exchange Act disclosing that such person or group has become the direct or indirect
"beneficial owner," as defined in Rule 13d-3 under the Exchange Act, of the common equity of Company representing more
than 50% of the voting power of such common equity.

	The consummation of (I) any recapitalization, reclassification or change of
the Shares (other than changes resulting from a subdivision or combination) as a result of which the Shares would be converted into, or
exchanged for, stock, other securities, other property or assets; (II) any share exchange, consolidation or merger of Company pursuant
to which the Shares will be converted into cash, securities or other property or assets; or (III) any sale, lease or other transfer in
one transaction or a series of transactions of all or substantially all of the consolidated assets of Company and its subsidiaries, taken as
a whole, to any person other than one of Company's subsidiaries; provided, however, that any merger of Company solely
for the purpose of changing its jurisdiction of incorporation that results in a reclassification, conversion or exchange of outstanding
Shares solely into shares of common stock of the surviving entity shall not constitute an Additional Termination Event pursuant to this
clause (B).  Notwithstanding the foregoing, any transaction or transactions set forth in clause (A) above or this clause (B) shall not
constitute an Additional Termination Event if (x) at least 90% of the consideration received or to be received by holders of the
Shares, excluding cash payments for fractional Shares and cash payments made in respect of dissenters' appraisal rights, in
connection with such transaction or transactions consists of shares of common stock that are listed or quoted on any of The New York
Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors)

                                            15

or will be so listed or quoted when issued or exchanged in connection with such transaction or transactions, and (y) as a result of such
transaction or transactions, the Shares will consist of such consideration, excluding cash payments for fractional Shares and cash
payments made in respect of dissenters' appraisal rights.

	Company's stockholders approve any plan or proposal for the liquidation or dissolution of
Company.

	Company's common stock ceases to be listed or quoted on any of The New York Stock Exchange, The
NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors).

	Dealer, despite using commercially reasonable efforts, is unable or reasonably determines that it is
impractical or illegal, to hedge its exposure with respect to the Transaction in the public market without registration under the Securities
Act or as a result of any legal, regulatory or self-regulatory requirements or related policies and procedures (whether or not such
requirements, policies or procedures are imposed by law or have been voluntarily adopted by Dealer).

	Default by Company or any of its significant subsidiaries (as defined below)
with respect to any mortgage, agreement or other instrument under which there may be outstanding, or by which there may be secured
or evidenced, any indebtedness for money borrowed in excess of $25.0 million (or its foreign currency equivalent) in the aggregate of
Company and/or any such subsidiary, whether such indebtedness now exists or shall hereafter be created (i) resulting in such
indebtedness becoming or being declared due and payable or (ii) constituting a failure to pay the principal of any such indebtedness
when due and payable at its stated maturity, upon required repurchase, upon declaration of acceleration or otherwise, and, in the case
of clauses (i) and (ii), such default is not cured or waived, such acceleration is not rescinded or such indebtedness is not paid or
discharged, as the case may be, within 30 days after notice to Company.  For purposes of this Section 9(h)(ii)(F), a
"significant subsidiary" is a subsidiary that is a "significant subsidiary" as defined in Article 1, Rule 1-02 of
Regulation S-X promulgated by the Securities and Exchange Commission; provided that in the case of a subsidiary that meets
the criteria of clause (3) thereof but not clause (1) or (2) thereof, such subsidiary shall not be a "significant subsidiary"
unless such subsidiary's income (or loss) from continuing operations before income taxes, extraordinary items and cumulative effect of
changes in accounting principles exclusive of amounts attributable to any non-controlling interests for the last completed fiscal year
prior to the date of such determination exceeds $10.0 million (or its foreign currency equivalent).

	No Setoff; No Collateral.  Notwithstanding any provision of
the Agreement or any other agreement between the parties to the contrary, the obligations of Company hereunder are not, and shall
not be, secured by any collateral.  Each
party waives any and all rights it may have to set off obligations arising under the Agreement and the Transaction against other
obligations between the parties, whether arising under any other agreement, applicable law or otherwise.

	Alternative Calculations and Payment on Early Termination and on
Certain Extraordinary Events.  

	If, in respect of the Transaction, an amount is payable by Company to Dealer, (A) pursuant to Section
12.7 or Section 12.9 of the Equity Definitions or (B) pursuant to Section 6(d)(ii) of the Agreement (any such amount, a
"Payment Obligation"), Company shall satisfy the Payment Obligation by the Share Termination Alternative (as
defined below), unless (a) Company gives irrevocable telephonic notice to Dealer, confirmed in writing within one Scheduled Trading
Day, no later than 12:00 p.m. (New

                                            16

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) Company remakes the representation set forth in Section 8(g) 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, Company shall deliver to Dealer the Share Termination Delivery Property on the
date (the "Share Termination Payment Date") on which the Payment Obligation would otherwise be due pursuant
to Section 12.7 or Section 12.9 of the Equity Definitions or Section 6(d)(ii) of the Agreement, as applicable, subject to Section 9(k)(i)
below, in satisfaction, subject to Section 9(k)(ii) below,  of the relevant Payment Obligation, in the manner reasonably requested by
Dealer free of payment.

	
Share Termination Delivery 
	 
	
Property: 
	
A number of Share Termination Delivery Units, as calculated by the Calculation Agent, equal
to the relevant Payment Obligation divided by the Share Termination Unit Price.  The Calculation Agent shall adjust the amount
of 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 (without giving effect to any
discount pursuant to Section 9(k)(i)).

	
Share Termination Unit Price: 
	
The value to Dealer of property contained in one Share Termination Delivery Unit on the date
such Share Termination Delivery Units are to be delivered as Share Termination Delivery Property, as determined by the Calculation
Agent in its discretion by commercially reasonable means.  In the case of a Private Placement of Share Termination Delivery Units that
are Restricted Shares (as defined below), as set forth in Section 9(k)(i) below, the Share Termination Unit Price shall be determined by
the discounted price applicable to such Share Termination Delivery Units.  In the case of a Registration Settlement of Share
Termination Delivery Units that are Restricted Shares (as defined below) as set forth in Section 9(k)(ii) below, notwithstanding the
foregoing, the Share Termination Unit Price shall be the Settlement Price 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.  The Calculation
Agent shall notify Company of the Share Termination Unit Price at the time of notification of such Payment Obligation to Company or, if
applicable, at the time the discounted price applicable to the relevant Share Termination Units is determined pursuant to Section 9(k)(i).

                                            17

	
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 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.  If such Nationalization, Insolvency or Merger Event involves a choice of Exchange
Property to be received by holders, such holder shall be deemed to have elected to receive the maximum possible amount of
cash.

	
Failure to Deliver: 
	
Inapplicable

	
Other applicable provisions: 
	
If Share Termination Alternative is applicable, the provisions of Sections 9.8, 9.9, 9.11 and
9.12 (as modified above) of the Equity Definitions 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.

	Registration/Private Placement Procedures.  If in the
reasonable determination of Dealer, based on the advice of counsel, Dealer, following any delivery of Shares or Share Termination
Delivery Property to Dealer hereunder, such Shares or Share Termination Delivery Property would be in the hands of Dealer subject to
any applicable restrictions with respect to any registration or qualification requirement or prospectus delivery requirement for such
Shares or Share Termination Delivery Property pursuant to any applicable federal or state securities law (including, without limitation,
any such requirement arising under Section 5 of the Securities Act as a result of such Shares or Share Termination Delivery Property
being subject to restrictions on resale under the Securities Act, or as a result of the sale of such Shares or Share Termination Delivery
Property being subject to paragraph (c) of Rule 145 under the Securities Act) (such Shares or Share Termination Delivery Property,
"Restricted Shares"), then delivery of such Restricted Shares shall be effected pursuant to either clause (i) or (ii)
below at the election of Company, unless Dealer waives the need for registration/private placement procedures set forth in (i) and (ii)
below.  Notwithstanding the foregoing, solely in respect of any Daily Number of Warrants exercised or deemed exercised on any
Expiration Date, Company shall elect, prior to the first Settlement Date for the First Expiration Date, a Private Placement Settlement or
Registration Settlement for all deliveries of Restricted Shares for all such Expiration Dates which election shall be applicable to all
remaining Settlement Dates for such Warrants and the procedures in clause (i) or clause (ii) below shall apply for all such delivered
Restricted Shares on an aggregate basis commencing after the final Settlement Date for such Warrants.  The Calculation Agent shall
make reasonable adjustments to settlement terms and provisions under this Confirmation to reflect a single Private Placement or
Registration Settlement for such aggregate Restricted Shares delivered hereunder.

	If Company elects to settle the Transaction pursuant to this clause (i) (a
"Private Placement Settlement"), then delivery of Restricted Shares by Company shall be

                                            18

effected in customary private placement procedures with respect to such Restricted Shares reasonably acceptable to Dealer; provided that Company
may not elect a Private Placement Settlement if, on the date of its election, it has taken, or caused to be taken, any action that would
make unavailable either the exemption pursuant to Section 4(2) of the Securities Act for the sale by Company to Dealer (or any affiliate
designated by Dealer) of the Restricted Shares or the exemption pursuant to Section 4(1) or Section 4(3) of the Securities Act for
resales of the Restricted Shares by Dealer (or any such affiliate of Dealer).  The Private Placement Settlement of such Restricted
Shares shall include customary representations, covenants, blue sky and other governmental filings and/or registrations, indemnities to
Dealer, due diligence rights (for Dealer or any designated buyer of the Restricted Shares by Dealer), opinions and certificates, and such
other documentation as is customary for private placement agreements of companies of comparable size, maturity and line of business,
all reasonably acceptable to Dealer.  In the case of a Private Placement Settlement, Dealer shall, subject to the execution by such
recipient of customary confidentiality agreements acceptable to Company, determine the appropriate discount to the Share Termination
Unit Price (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j) above) or any Settlement Price (in the
case of settlement of Shares pursuant to Section 2 above) applicable to such Restricted Shares in a commercially reasonable manner
and appropriately adjust the number of such Restricted Shares to be delivered to Dealer hereunder.  Notwithstanding anything to the
contrary in the Agreement or this Confirmation, the date of delivery of such Restricted Shares shall be the Exchange Business Day
following notice by Dealer to Company, of such applicable discount and the number of Restricted Shares to be delivered pursuant to
this clause (i).  For the avoidance of doubt, delivery of Restricted Shares shall be due as set forth in the previous sentence and not be
due on the Share Termination Payment Date (in the case of settlement of Share Termination Delivery Units pursuant to Section 9(j)
above) or on the Settlement Date for such Restricted Shares (in the case of settlement in Shares pursuant to Section 2
above).

	If Company elects to settle the Transaction pursuant to this clause (ii) (a
"Registration Settlement"), then Company shall promptly (but in any event no later than the beginning of the Resale
Period) file and use its reasonable best efforts to make effective under the Securities Act a registration statement or supplement or
amend an outstanding registration statement in form and substance reasonably satisfactory to Dealer, to cover the resale of such
Restricted Shares in accordance with customary resale registration procedures, including covenants, conditions, representations,
underwriting discounts (if applicable), commissions (if applicable), indemnities due diligence rights, opinions and certificates, and such
other documentation as is customary for equity resale underwriting agreements of companies of comparable size, maturity and line of
business, all reasonably acceptable to Dealer.  If Dealer, in its sole reasonable discretion, is not satisfied with such procedures and
documentation Private Placement Settlement shall apply.  If Dealer is satisfied with such procedures and documentation, it shall sell the
Restricted Shares pursuant to such registration statement during a period (the "Resale Period") commencing on
the Exchange Business Day following delivery of such Restricted Shares (which, for the avoidance of doubt, shall be (x) the Share
Termination Payment Date in case of settlement in Share Termination Delivery Units pursuant to Section 9(j) above or (y) the
Settlement Date in respect of the final Expiration Date for all Daily Number of Warrants) and ending on the earliest of (i) the Exchange
Business Day on which Dealer completes the sale of all Restricted Shares or, in the case of settlement of Share Termination Delivery
Units, a sufficient number of Restricted Shares so that the realized net proceeds of such sales equals or exceeds the Payment
Obligation (as defined above), (ii) the date upon which all Restricted Shares have been sold or transferred pursuant to Rule 144 (or
similar provisions then in force) or Rule 145(d)(2) (or any similar provision then in force) under the Securities Act and (iii) the date upon
which all Restricted Shares may be sold or transferred by a non-affiliate pursuant to Rule 144 (or any similar provision then in force) or
Rule 145(d)(2) (or any similar provision then in force) under the Securities Act.  If the Payment Obligation exceeds the realized net

                                            19

proceeds from such resale, Company shall transfer to Dealer by the open of the regular trading session on the Exchange on the
Exchange Trading Day immediately following the last day of the Resale Period the amount of such excess (the "Additional
Amount") in cash or in a number of Shares ("Make-whole Shares") in an amount that, based on the
Settlement Price on the last day of the Resale Period (as if such day were the "Valuation Date" for purposes of computing
such Settlement Price), has a dollar value equal to the Additional Amount.  The Resale Period shall continue to enable the sale of the
Make-whole Shares.  If Company elects to pay the Additional Amount in Shares, the requirements and provisions for Registration
Settlement shall apply.  This provision shall be applied successively until the Additional Amount is equal to zero.  In no event shall
Company deliver a number of Restricted Shares greater than the Maximum Number of Shares.

	If the Private Placement Settlement or the Registration Settlement shall not be effected as set forth in
clauses (i) or (ii), as applicable, then failure to effect such Private Placement Settlement or such Registration Settlement shall constitute
an Event of Default with respect to which Company shall be the Defaulting Party.

	Limit on Beneficial Ownership.  Notwithstanding any other provisions hereof, Dealer may
not exercise any Warrant hereunder or be entitled to take delivery of any Shares deliverable hereunder, and Automatic Exercise shall
not apply with respect to any Warrant hereunder, to the extent (but only to the extent) that, after such receipt of any Shares upon the
exercise of such Warrant or otherwise hereunder [and after taking into account any Shares deliverable by Dealer under the letter
agreement dated August [__], 2013 between Dealer and Company regarding Base Warrants (the "Base Warrant
Confirmation")]5, (i) the Section 16 Percentage would exceed 7.5%, or (ii) the Share Amount would exceed the Applicable
Share Limit.  Any purported delivery hereunder shall be void and have no effect to the extent (but only to the extent) that, after such
delivery [and after taking into account any Shares deliverable by Dealer under the Base Warrant Confirmation]6, (i) the Section 16
Percentage would exceed 7.5%, or (ii) the Share Amount would exceed the Applicable Share Limit. If any delivery owed to Dealer
hereunder is not made, in whole or in part, as a result of this provision, Company's obligation to make such delivery shall not be
extinguished and Company shall make such delivery as promptly as practicable after, but in no event later than one Business Day after,
Dealer gives notice to Company that, after such delivery, (i) the Section 16 Percentage would not exceed 7.5%, and (ii) the Share
Amount would not exceed the Applicable Share Limit. 

	Share Deliveries.  Company acknowledges and agrees that, to the extent the holder of this
Warrant is not then an affiliate and has not been an affiliate for 90 days (it being understood that Dealer will not be considered an
affiliate under this paragraph solely by reason of its receipt of Shares pursuant to the Transaction), and otherwise satisfies all holding
period and other requirements of Rule 144 of the Securities Act applicable to it, (i) any Shares or Share Termination Delivery Property
delivered hereunder at any time after 6 months from the Trade Date (or 1 year from the Trade Date if, at such time, informational
requirements of Rule 144(c) are not satisfied with respect to Company), and (ii) any Restricted Shares after the period of 6 months (or 1
year if, at such time, informational requirements of Rule 144(c) under the Securities Act are not satisfied with respect to Company) has
elapsed from the applicable Settlement Date or Share Termination Payment Date, in each case, shall be eligible for resale under Rule
144 of the Securities Act and Company agrees to promptly remove, or cause the transfer agent for such Shares, Share Termination
Delivery Property or Restricted Shares, to remove, any legends referring to any restrictions on resale under the Securities Act from
such Shares, Share Termination Delivery Property or Restricted Shares upon request by Dealer to Company or such transfer agent,
without any requirement for the delivery of any certificate, consent, agreement, opinion of counsel, notice or any other document, any
transfer tax stamps or payment of any other amount or any other action by Dealer.  Company further agrees that (i) any Shares or
Share Termination Delivery Property delivered hereunder prior to the date that is 6 months from the Trade Date (or 1 year from

the Trade Date if, at such time, informational requirements of Rule 144(c) are not satisfied with respect to Company), and (ii) any Restricted
Shares at any time before the period of 6 months (or 1 year if, at such time, informational requirements of Rule 144(c) under the
Securities Act are not satisfied with respect to Company) has elapsed from the applicable Settlement Date or Share Termination
Payment Date, in each case, may be transferred by and among Dealer and its affiliates and Company shall effect such transfer without
any further action by Dealer, and any affiliate to which such Shares, Share Termination Delivery Property or Restricted Shares is
transferred may request removal of any legends on such Shares, Share Termination Delivery Property or Restricted Shares, as the
case may be, pursuant to the immediately preceding sentence.  Notwithstanding anything to the contrary herein, Company agrees that
any delivery of Shares, Share Termination Delivery Property or Restricted Shares shall be effected by book-entry transfer through the
facilities of DTC, or any successor depositary, if at the time of delivery, such class of Shares, class of Share Termination Delivery
Property or class or Restricted Shares is in book-entry form at DTC or such successor depositary.  Notwithstanding anything to the
contrary herein, to the extent the provisions of Rule 144 of the Securities Act or any successor rule are amended, or the applicable
interpretation thereof by the Securities and Exchange Commission or any court change after the Trade Date, the agreements of
Company herein shall be deemed modified to the extent necessary, in the opinion of outside counsel of Company, to comply with Rule
144 of the Securities Act or any successor rule, as in effect at the time of delivery of the relevant Shares, Share Termination Delivery
Property or Restricted Shares.

	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 the other 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.

	Tax Disclosure.  Effective from the date of commencement of discussions concerning the
Transaction, Company 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 Company relating to such tax treatment and tax structure.

	Maximum Share Delivery.  

	Notwithstanding any other provision of this
Confirmation, the Agreement or the Equity Definitions, in no event will Company at any time be required to deliver a number of Shares
greater than two times the Number of Shares (the "Maximum Number of Shares") to Dealer in connection with the
Transaction, including, without limitation, any Shares deliverable to Dealer as a result of any early termination of the
Transaction.

	In the event Company shall not have delivered to Dealer the full number of
Shares or Restricted Shares otherwise deliverable by Company to Dealer pursuant to the terms of the Transaction because Company
has insufficient authorized but unissued Shares (such deficit, the "Deficit Shares"), Company shall be continually
obligated to deliver, from time to time, Shares or Restricted Shares, as the case may be, to Dealer until the full number of Deficit Shares
have been delivered pursuant to this Section 9(p)(ii), when, and to the extent that, (A) Shares are repurchased, acquired or otherwise
received by Company or any of its subsidiaries after the Trade Date (whether or not in exchange for cash, fair value or any other
consideration), (B) authorized and unissued Shares reserved for issuance in respect of other transactions prior to such date that prior to
the relevant date become no longer so reserved or (C) Company additionally authorizes any unissued Shares that are not reserved for
other transactions; provided that in no event shall Company deliver any Shares or Restricted Shares to Dealer pursuant to this
Section 9(p)(ii) to the extent that such delivery would cause the aggregate number of Shares and Restricted Shares delivered to Dealer to exceed the Maximum Number of Shares.

                                             21

Company shall immediately notify Dealer of the occurrence of any of the foregoing events
(including the number of Shares subject to clause (A), (B) or (C) and the corresponding number of Shares or Restricted Shares, as the
case may be, to be delivered) and promptly deliver such Shares or Restricted Shares, as the case may be,
thereafter.

	Right to Extend.  Dealer may postpone or add, in whole or in part, any Expiration Date or
any other date of valuation or delivery with respect to some or all of the relevant Warrants (in which event the Calculation Agent shall
make appropriate adjustments to the Daily Number of Warrants with respect to one or more Expiration Dates) if Dealer determines, in
its commercially reasonable judgment, that such extension is reasonably necessary or appropriate to preserve Dealer's hedging or
hedge unwind activity hereunder in light of existing liquidity conditions to effect transactions in Shares in connection with its hedging,
hedge unwind or settlement activity hereunder in a manner that would, if Dealer were Issuer or an affiliated purchaser of Issuer, be in
compliance with applicable legal, regulatory or self-regulatory requirements, or with related policies and procedures applicable to
Dealer.

	Status of Claims in Bankruptcy.  Dealer acknowledges and agrees that this Confirmation is
not intended to convey to Dealer rights against Company with respect to the Transaction that are senior to the claims of common
stockholders of Company in any United States bankruptcy proceedings of Company; provided that nothing herein shall limit or
shall be deemed to limit Dealer's right to pursue remedies in the event of a breach by Company 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.

	Securities Contract; Swap Agreement.  The parties hereto intend for (i) the Transaction to
be a "securities contract" and a "swap agreement" as defined in the Bankruptcy Code (Title 11 of the United
States Code) (the "Bankruptcy Code"), and the parties hereto to be entitled to the protections afforded by, among
other Sections, Sections 362(b)(6), 362(b)(17), 546(e), 546(g), 555 and 560 of the Bankruptcy Code, (ii) a party's right to liquidate the
Transaction and to exercise any other remedies upon the occurrence of any Event of Default under the Agreement with respect to the
other party to constitute a "contractual right" as described in the Bankruptcy Code, and (iii) 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.

	Wall Street Transparency and Accountability Act.  In connection with Section 739 of the
Wall Street Transparency and Accountability Act of 2010 ("WSTAA"), the parties hereby agree that neither the
enactment of WSTAA or any regulation under the WSTAA, nor any requirement under WSTAA or an amendment made by WSTAA,
shall 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, regulatory
change or similar event under this Confirmation, the Equity Definitions incorporated herein, or the Agreement (including, but not limited
to, rights arising from Change in Law, Hedging Disruption, Increased Cost of Hedging, an Excess Ownership Position, or Illegality (as
defined in the Agreement)).

	Agreements and Acknowledgements Regarding Hedging.
Company understands, acknowledges and agrees that: (A) at any time on and prior to the last 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, when or in what manner any hedging or market activities in securities of Issuer shall be conducted and shall do so in a manner
that it deems appropriate to hedge its price and market risk with respect to the Settlement 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 Settlement Prices, each in a
manner that may be adverse to Company.

                                             22

	Early Unwind. In the event the sale of the ["Firm]7
["Additional]8 Securities" (as defined in the Purchase Agreement) is not consummated with the Initial Purchasers for any
reason, or Company fails to deliver to Dealer opinions of counsel as required pursuant to Section 9(a), in each case by 5:00 p.m. (New
York City time) on the Premium Payment Date, or such later date as agreed upon by the parties (the Premium Payment Date or such
later date the "Early Unwind Date"), the Transaction shall automatically terminate (the "Early
Unwind"), on the Early Unwind Date and (i) the Transaction and all of the respective rights and obligations of Dealer and
Company under the Transaction shall be cancelled and terminated and (ii) each party shall be released and discharged by the other
party from and agrees not to make any claim against the other party with respect to any obligations or liabilities of the other party arising
out of and to be performed in connection with the Transaction either prior to or after the Early Unwind Date; provided that
Company shall elect (i) to purchase from Dealer on the Early Unwind Date all Shares purchased by Dealer or one or more of its
affiliates in connection with the Transaction (the "Existing Hedge Shares") at the aggregate price Dealer or any
such affiliate paid for such Shares (the "Early Unwind Amount") or (ii) for Dealer to sell the Existing Hedge Shares
during a period (the "Unwind Resale Period") commencing on the Exchange Business Day following the Early
Unwind Date and ending on the Exchange Business Day on which Dealer completes the sale of all Existing Hedge Shares (and any
Make-whole Unwind Shares (as defined below), if applicable).  If the Early Unwind Amount exceeds the realized net proceeds from the
sale by Dealer of the Existing Hedge Shares, Company shall transfer to Dealer by the open of the regular trading session on the
Exchange on the Exchange Trading Day immediately following the last day of the Unwind Resale Period the amount of such excess
(the "Additional Unwind Amount"), at Company's election, in cash or in a number of Shares ("Make-whole
Unwind Shares") in an amount that, based on the estimated per Share resale value of such Make-whole Unwind Shares (as
determined by the Calculation Agent in a commercially reasonable manner), has a value equal to the Additional Unwind Amount. The
Unwind Resale Period shall continue to enable the sale of the Make-whole Unwind Shares and this provision shall be applied
successively until the Additional Unwind Amount is equal to zero. In connection with the sale of any Existing Hedge Shares and any
Make-whole Unwind Shares pursuant to this Section 9(v), Company shall, at its election, either (i) in order to allow Dealer to sell such
Existing Hedge Shares and such Make-whole Unwind Shares in a registered offering, make available to Dealer an effective registration
statement under the Securities Act and enter into an agreement, in customary form and substance reasonably satisfactory to Dealer,
substantially in the form of an underwriting agreement for a registered secondary offering of equity securities of companies comparable
in size, maturity and line of business (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) of this sentence shall apply) or (ii) in order to allow Dealer to sell such Existing Hedge Shares and
such Make-whole Unwind 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 of companies comparable in size, maturity and
line of business, in customary form and substance reasonably satisfactory to Dealer (it being understood and agreed that the sale price
for such Existing Hedge Shares and such Make-whole Unwind Shares pursuant to this clause (ii) shall reflect a commercially
reasonable liquidity discount from the public market price of the Shares). In no event shall Company deliver a number of Shares
pursuant to this Section 9(v) greater than the Maximum Number of Shares.  Each of Dealer and Company represents and
acknowledges to the other that, subject to the proviso included in this Section 9(v), upon an Early Unwind, all obligations with respect to
the Transaction shall be deemed fully and finally discharged.

	Payment by Dealer. In the event that, following payment of the Premium, (i) 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, Dealer owes to Company an amount calculated under Section 6(e) of

                                             23

the Agreement, or (ii) Dealer owes to Company, pursuant to Section 12.7 or Section 12.9 of
the Equity Definitions, an amount calculated under Section 12.8 of the Equity Definitions, such amount shall be deemed to be
zero.

	Delivery or Receipt of Cash. For the avoidance of doubt, other than receipt of the Premium
by Company, nothing in this Confirmation shall be interpreted as requiring Company to deliver or receive cash in respect of the
settlement of the Transaction contemplated by this Confirmation, except in circumstances where the cash settlement thereof is within
Company's control (including, without limitation, where an Event of Default by Company has occurred under Section 5(a)(ii) or Section
5(a)(iv) of the Agreement, where Company elects to deliver or receive cash, where Company fails timely to elect to deliver or receive
Share Termination Delivery Property in respect of the settlement of such Transaction or where Company has made Private Placement
Settlement in accordance with Section 9(k)(i) unavailable due to the occurrence of events within its control) or in those circumstances in
which holders of the Shares would also receive cash.

	Exemption from Registration. Each of Dealer and Company acknowledges that the offer
and sale of the Transaction to it is intended to be exempt from registration under the Securities Act, by virtue of Section 4(a)(2) thereof.
Accordingly, Dealer represents and warrants to Company that (i) it has the financial ability to bear the economic risk of its investment in
the Transaction and is able to bear a total loss of its investment and its investments in and liabilities in respect of the Transaction, which
it understands are not readily marketable, are not disproportionate to its net worth, and it is able to bear any loss in connection with the
Transaction, including the loss of its entire investment in the Transaction, (ii) it is an "accredited investor" as that term is
defined in Regulation D as promulgated under the Securities Act, (iii) it is entering into the Transaction for its own account and without a
view to the distribution or resale thereof, (iv) the assignment, transfer or other disposition of the Transaction has not been and will not
be registered under the Securities Act and is restricted under this Confirmation, the Securities Act and state securities laws, and (v) its
financial condition is such that it has no need for liquidity with respect to its investment in the Transaction and no need to dispose of any
portion thereof to satisfy any existing or contemplated undertaking or indebtedness and is capable of assessing the merits of and
understanding (on its own behalf or through independent professional advice), and understands and accepts, the terms, conditions and
risks of the Transaction.

                                            24

Please confirm that the foregoing correctly sets forth the terms of the agreement between Dealer and
Company with respect to the Transaction, by manually signing this Confirmation or this page hereof as evidence of agreement to such
terms and providing the other information requested herein and returning an executed copy to Dealer.
