MASTER TERMS AND CONDITIONS FOR CAPPED CALL TRANSACTIONS

BETWEEN BANK OF AMERICA, N.A. AND CEMEX, S.A.B. de C.V.

The purpose of this Master Terms and Conditions for Capped Call Transactions (this Master Confirmation), dated as of March 9, 2011, is to set forth certain terms and conditions for
capped call option transactions that CEMEX, S.A.B. de C.V. (Counterparty) will enter into with Bank of America, N.A. (Dealer). Each such transaction (a Transaction) entered into between Dealer
and Counterparty that is to be subject to this Master Confirmation shall be evidenced by a written confirmation substantially in the form of Exhibit A hereto, with such modifications thereto as to which Counterparty and Dealer mutually agree (a
Confirmation). This Master Confirmation and each Confirmation together constitute a Confirmation as referred to in the Agreement specified below.

This Master Confirmation and a Confirmation evidence a complete binding agreement between you and us as to the terms of the Transaction
to which this Master Confirmation and such Confirmation relates. This Master Confirmation and each Confirmation hereunder shall supplement, form a part of, and be subject to an agreement in the form of the 1992 ISDA Master Agreement (Multicurrency
 Cross Border) as if we had executed an agreement in such form (with a Schedule that had the provisions in Section 15 of this Master Confirmation and the other elections set forth in this Master Confirmation) on the Trade Date and such
agreement shall be considered the Agreement hereunder.

The Transactions governed by this Master
Confirmation shall be the sole Transactions under the Agreement. If there exists any ISDA Master Agreement between Dealer and Counterparty or any confirmation or other agreement between Dealer and Counterparty pursuant to which an ISDA Master
Agreement is deemed to exist between Dealer and Counterparty, then notwithstanding anything to the contrary in such ISDA Master Agreement, such confirmation or agreement or any other agreement to which Dealer and Counterparty are parties, the
Transactions governed by this Master Confirmation shall not be considered Transactions under, or otherwise governed by, such existing or deemed ISDA Master Agreement.

The definitions and provisions contained in the 2002 ISDA Equity Derivatives Definitions as supplemented by the 2007 Partial Lookthrough Depository Receipt Supplement to the 2002 ISDA Equity Derivatives
Definitions (as amended in this Master Confirmation, the DR Supplement and the 2002 ISDA Equity Derivatives Definitions as so supplemented, the Definitions), each as published by ISDA are incorporated into this
Master Confirmation.

THIS MASTER CONFIRMATION WILL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF
NEW YORK, WITHOUT REFERENCE TO CHOICE OF LAW DOCTRINE. THE PARTIES HERETO IRREVOCABLY SUBMIT TO THE EXCLUSIVE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK AND THE UNITED STATES COURT FOR THE SOUTHERN DISTRICT OF NEW YORK, AND TO THE
JURISDICTION OF THEIR OWN CORPORATE DOMICILE, IN RESPECT OF ACTIONS BROUGHT AGAINST SUCH PARTY AS A DEFENDANT, IN CONNECTION WITH ALL MATTERS RELATING HERETO AND WAIVE ANY OBJECTION TO THE LAYING OF VENUE IN, AND ANY CLAIM OF INCONVENIENT FORUM WITH
RESPECT TO, THESE COURTS, AND ANY RIGHT TO WHICH ANY OF THEM MAY BE ENTITLED ON ACCOUNT OF PLACE OF RESIDENCE OR DOMICILE.

1.
In the event of any inconsistency between this Master Confirmation, on the one hand, and the Definitions or the Agreement, on the other hand, this Master Confirmation will control for the purpose of the Transaction to which a Confirmation relates.
In the event of any inconsistency between the Definitions, the Agreement and this Master Confirmation, on the one hand, and a Confirmation, on the other hand, the Confirmation will govern. With respect to a Transaction, capitalized terms used herein
that are not otherwise defined shall have the meaning assigned to them in the Confirmation relating to such Transaction.

2. Each party will make each payment specified in this Master Confirmation or a Confirmation
as being payable by such party, not later than the due date for value on that date in the place of the account specified below or otherwise specified in writing, in freely transferable funds and in a manner customary for payments in the required
currency.

3. Confirmations and General Terms:

This Master Confirmation and the Agreement, together with the Confirmation relating to a Transaction, shall constitute the written
agreement between Counterparty and Dealer with respect to such Transaction.

Each Transaction to which a Confirmation relates
is a Capped Call Option Transaction, which shall be considered a Share Option Transaction for purposes of the Definitions (with references to Strike Price therein deemed to include Lower Strike Price and/or Upper Strike
Price, as applicable), and shall have the following terms:

|Dividend Adjustments: |  | If at any time during the period from and including the date that is one Settlement Cycle following the Trade Date to but excluding the date that is one Settlement Cycle following
the Expiration Date a record date for a distribution, dividend or recapitalization of retained earnings by an Underlying Issuer occurs, then, and upon consultation with Buyer which shall be taken into account in good faith by the Calculation Agent,
(i) if such event (including, for the avoidance of doubt, a recapitalization of retained earnings by an Underlying Issuer) results in a corresponding record date (whether or not falling on the same date) for a Share dividend (excluding a Share
dividend in connection with a circumstance described in clause (ii) below), the Calculation Agent (x) shall make an adjustment to the Lower Strike Price and the Option Entitlement that corresponds to the adjustment methodology for such type of
dividend set forth in the Indenture (as set forth in the Confirmation for such Transaction) and (y) shall make a proportionate adjustment to the Upper Strike Price on the same basis as the adjustment to the Lower Strike Price described above, and
(ii) if (1) such event results in a corresponding record date for a cash dividend on the Shares or both a Share dividend and a cash dividend on the Shares, (2) the holders of the Shares would be entitled to elect the form of consideration they
receive, including the right to acquire Shares with a cash dividend, or would not be entitled to receive the entire distribution of Underlying Shares in Shares with respect to a corresponding record date for such event, (3) such event results in
both (x) a change to the number of Underlying Shares represented, directly or indirectly, by a Share and (y) an adjustment to the Conversion Rate (as defined in the Indenture) for the Convertible Notes (as set forth in the Confirmation
for such Transaction) and/or (4) with respect to such event, Counterparty makes a discretionary adjustment to the Conversion Rate (as defined in the Indenture) for the Convertible Notes or determines under the Indenture that the
adjustments set forth in the Indenture do not provide a fair and equitable result, then the Calculation Agent (A) shall make an adjustment to the Lower Strike Price and the Option Entitlement that corresponds to the adjustment methodology for such
type of dividend set forth in the Indenture and (B) shall make adjustments consistent with the Calculation Agent Adjustment provision in Section 11.2(c) of the Definitions (as modified herein) to the Upper Strike Price and/or any other term of the
Transaction (except the Lower Strike Price and Option Entitlement) to preserve the fair value of the Transaction after taking into account the effect of such event (including whether such event, taken as a whole, effectively resulted in a Share
dividend) and any adjustment made pursuant to clause (ii)(A) above; provided that, notwithstanding the foregoing, if Counterparty does not initially make an adjustment to the Conversion Rate with respect to such event due to the
prescribed adjustment not reaching the one percent threshold for such adjustments described in the Indenture, no adjustment will be made pursuant to clauses (i) or (ii) with respect to such event
until

12. Miscellaneous:

(a) Early Termination. The parties agree that Second Method and Loss will apply to each Transaction under this Master Confirmation as such terms are defined under the 1992 ISDA Master Agreement
(Multicurrency-Cross Border).

(b) Repurchase Notices. Counterparty shall, on any day on which Counterparty effects any
repurchase of Shares or Underlying Shares, promptly give Dealer a written notice of such repurchase (a Repurchase Notice) on such day if, following such repurchase, the Ratio Equity Percentage as determined on such day is
(i) equal to or greater than 8.0% and (ii) greater by 0.5% than the Ratio Equity Percentage included in the immediately preceding Repurchase Notice (or, in the case of the first such Repurchase Notice, greater by 0.5% than the Ratio Equity
Percentage as of the date hereof). The Ratio Equity Percentage as of any day is the fraction the numerator



9



---

of which is the aggregate of the Base Amounts for (1) all Tranches for all Transactions hereunder, (2) all transactions of the type described in the definition of Specified
Transactions relating to Shares or Underlying Shares between Dealer and Counterparty or their respective Affiliates and (3) all transactions of the type described in the definition of Specified Transactions relating to Shares
or Underlying Shares between Dealer or its Affiliates and trusts or other entities with respect to which the beneficiaries or grantors (however described) are Counterparty, its Affiliates and/or employees of Counterparty or its Affiliates (the
transactions described in clauses (1), (2) and (3) collectively, the Specified Portfolio) and the denominator of which is the number of Underlying Shares outstanding on such day and the Base Amount for
a Tranche or a transaction is an amount equal to the product of the Number of Shares (or similar term in the relevant transaction) for such Tranche or transaction, as applicable and, if such Tranche or transaction is denominated in Shares, the
number of Underlying Shares represented by a Share.

(c) Section 16 Indemnity. If Counterparty ceases to be a
foreign private issuer (as defined in Rule 3b-4 under the Exchange Act) at any time during the term of this Transaction, Counterparty agrees to indemnify and hold harmless Dealer and its Affiliates and their respective officers,
directors and controlling persons (each, a Section 16 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,
subject to the reporting and profit disgorgement provisions of Section 16 of the Exchange Act, including without limitation, any forbearance from hedging activities or cessation of hedging activities and any losses in connection therewith with
respect to any Transaction), claims, damages, judgments, liabilities and expenses (including reasonable attorneys fees), joint or several, to which a Section 16 Indemnified Person may become subject, 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 (b), and to reimburse, upon written request, each such Section 16 Indemnified Person for any reasonable 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 any Section 16 Indemnified Person, such Section 16 Indemnified Person shall promptly notify Counterparty in writing, and Counterparty, upon request of such Section 16 Indemnified Person, shall
retain counsel reasonably satisfactory to such Section 16 Indemnified Person to represent such Section 16 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 be relieved from liability to the extent that such Section 16 Indemnified Person fails to promptly notify Counterparty of any action commenced against it in respect of which indemnity may be sought
hereunder; provided that failure to notify Counterparty (i) shall not relieve Counterparty from any liability hereunder to the extent it is not materially prejudiced as a result thereof and (ii) shall not, in any event, relieve
Counterparty from any liability that it may have otherwise than on account of this paragraph (c). Counterparty 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, Counterparty agrees to indemnify any Section 16 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 each Section 16 Indemnified Person, effect any settlement of any pending or threatened proceeding in respect of which any Section 16 Indemnified Person is or could have been a party and indemnity could have been sought hereunder
by any such Section 16 Indemnified Person, unless such settlement includes an unconditional release of each such Section 16 Indemnified Person from all liability on claims that are the subject matter of such proceeding on terms reasonably
satisfactory to each such Section 16 Indemnified Person. If the indemnification provided for in this paragraph (c) is unavailable to a Section 16 Indemnified Person or insufficient in respect of any losses, claims, damages or
liabilities referred to therein, then Counterparty, in lieu of indemnifying such Section 16 Indemnified Person thereunder, shall contribute to the amount paid or payable by such Section 16 Indemnified Person as a result of such losses,
claims, damages or liabilities. The remedies provided for in this paragraph (c) are not exclusive and shall not limit any rights or remedies that may otherwise be available to any Section 16 Indemnified Person at law or in equity. The
indemnity and contribution agreements contained in this paragraph (c) shall remain operative and in full force and effect regardless of the termination of any Transaction.

(d) Transfer or Assignment. Dealer may, with Counterpartys prior written consent (not to be unreasonably withheld or
delayed), transfer or assign all (but not less than all) of its rights and obligations under any Transaction to any of its Affiliates with a rating (or whose guarantor has a rating) for its long term, unsecured and unsubordinated indebtedness equal
to or better than A- by Standard & Poors Ratings Services or its successor (S&P), or A3 by Moodys Investors Service, Inc. or its successor (Moodys) or, if either S&P or
Moodys



10



---

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 Counterparty shall not withhold or
delay its consent if Dealer certifies to Counterparty that the requested transfer is made in connection with the transfer of all or substantially all similar transactions that Dealer and its affiliates are parties thereto resulting from the
enactment of the Dodd Frank Wall Street Reform and Consumer Protection Act of 2010 and rules and regulation thereunder, and such transfer will not result in an increased cost to Counterparty. Counterparty may, with Dealers prior written
consent (not to be unreasonably withheld or delayed) sell or pledge to any third party all (but not less than all) of its rights and obligations under any Transaction at a time when such Transaction is not subject to a security interest in favor of
Dealer or any of its Affiliates. If, as determined in Dealers sole discretion, (a) at any time (1) the Equity Percentage exceeds 8.5%, (2) Dealer, Dealer Group (as defined below) or any person whose ownership position would be
aggregated with that of Dealer or Dealer Group (Dealer, Dealer Group or any such person, a Dealer Person) under U.S. federal, non-U.S., state or local laws, regulations or regulatory orders applicable to ownership of Shares or
Underlying Shares (Applicable Laws), owns, beneficially owns, constructively owns, controls, holds the power to vote or otherwise meets a relevant definition of ownership, or could be reasonably viewed as meeting any of the
foregoing, in excess of a number of Shares or Underlying Shares, as applicable, equal to (x) the number of Shares or Underlying Shares, as applicable, that would give rise to reporting, registration, filing or notification obligations or other
requirements (including obtaining prior approval by a state, U.S. federal or non-U.S. regulator) of a Dealer Person under Applicable Laws and with respect to which such requirements have not been met or the relevant approval has not been received
minus (y) 1% of the number of Shares or Underlying Shares, as applicable, outstanding on the date of determination or (3) the Ratio Equity Percentage exceeds 9.9% (any such condition described in clause (1), (2) or (3), an
Excess Ownership Position) and (b) Dealer is unable, after commercially reasonable efforts, to effect a transfer or assignment on pricing and terms and within a time period reasonably acceptable to it of all or a portion of
one or more Transactions pursuant to the preceding paragraph such that an Excess Ownership Position no longer exists, Dealer may designate any Scheduled Trading Day as an Early Termination Date with respect to a portion (the Terminated
Portion) of any Transaction(s), such that an Excess Ownership Position no longer exists following such partial termination. In the event that Dealer so designates an Early Termination Date with respect to a portion of any Transaction(s), a
payment shall be made pursuant to Section 6 of the Agreement as if (i) an Early Termination Date had been designated in respect of a Transaction having terms identical to the Terminated Portion of the Transaction(s), (ii) Counterparty
shall be the sole Affected Party with respect to such partial termination and (iii) such portion of the Transaction(s) shall be the only Terminated Transaction. The Equity Percentage as of any day is the fraction, expressed
as a percentage, (A) the numerator of which is the number of Underlying Shares that Dealer and any of its affiliates subject to aggregation with Dealer for purposes of the beneficial ownership test under Section 13 of the
Exchange Act and all persons who may form a group (within the meaning of Rule 13d-5(b)(1) under the Exchange Act) with Dealer (collectively, Dealer Group) beneficially own (within the meaning of
Section 13 of the Exchange Act) in connection with transactions in the Specified Portfolio without duplication on such day (or, if Counterparty ceases to be a foreign private issuer (as defined in Rule 3b-4 under the Exchange Act)
and the equivalent calculation under Section 16 of the Exchange Act and the rules and regulations thereunder results in a higher number, such number) and (B) the denominator of which is the number of Underlying Shares outstanding on such
day.

(e) Severability; Illegality. If compliance by either party with any provision of a Transaction would be
unenforceable or illegal, (i) the parties shall negotiate in good faith to resolve such unenforceability or illegality in a manner that preserves the economic benefits of the transactions contemplated hereby and (ii) the other provisions
of the Transaction shall not be invalidated, but shall remain in full force and effect.

(f) Waiver of Trial by Jury.
EACH OF COUNTERPARTY AND DEALER HEREBY IRREVOCABLY WAIVES (ON ITS OWN BEHALF AND, TO THE EXTENT PERMITTED BY APPLICABLE LAW, ON BEHALF OF ITS STOCKHOLDERS) ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED ON
CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO ANY TRANSACTION OR THIS MASTER CONFIRMATION OR THE ACTIONS OF DEALER OR ITS AFFILIATES IN THE NEGOTIATION, PERFORMANCE OR ENFORCEMENT THEREOF.

(g) Confidentiality. Notwithstanding any provision in this Master Confirmation, any Confirmation or the Agreement, in connection
with Section 1.6011-4 of the Treasury Regulations, the parties hereby



11



---

agree that each party (and each employee, representative, or other agent of such party) may disclose to any and all persons, without limitation of any kind, the U.S. tax treatment and U.S. tax
structure of the Transaction and all materials of any kind (including opinions or other tax analyses) that are provided to such party relating to such U.S. tax treatment and U.S. tax structure, other than any information for which nondisclosure is
reasonably necessary in order to comply with applicable securities laws.

(h) Securities Contract; Swap Agreement. The
parties hereto intend for: (i) each Transaction hereunder 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),
a derivatives transaction under the Mexican Ley de Concursos Mercantiles, the Agreement to be a master netting agreement and the parties hereto to be entitled to the protections afforded by, among other Sections, Sections
362(b)(6), 362(b)(17), 362(o), 546(e), 546(g), 546(j), 548(d), 555, 560 and 561 of the Bankruptcy Code and the applicable provisions of theLey de Concursos Mercantiles; (ii) a partys right to liquidate a 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  to cause the liquidation, termination or acceleration and any payments
owed under this Transaction or the Agreement with respect thereto to be a termination value, payment amount or other transfer obligation, in each case as described in the Bankruptcy Code; (iii) all payments
for, under or in connection with a Transaction to constitute margin payments, settlement payments and/or transfers under a securities contract and/or swap agreement as defined in the
Bankruptcy Code; and (iv) each party hereto to be a master netting agreement participant, financial institution, swap participant and/or a financial participant as defined in the Bankruptcy Code.

(i) Extension of Settlement. Dealer may postpone any Expiration Date, postpone the Final
Disruption Date and/or add additional Expiration Dates with respect to some or all of the Options under any Tranche hereunder (provided that none of such postponed or added Expiration Dates shall occur later than the 20thScheduled Trading Day immediately succeeding the last Expiration
Date (determined without regard to this provision) for the relevant Transaction) if Dealer determines, in its reasonable discretion, that such extension is necessary or advisable to preserve Dealers hedging activity hereunder in light of
existing liquidity conditions or to enable Dealer to effect purchases or sales of Shares or Underlying Shares in connection with its hedging activity hereunder in a manner that would, if Dealer were Counterparty or an affiliated purchaser of
Counterparty, be in compliance with applicable legal and regulatory requirements or self-regulatory requirements, or with related reasonable policies and procedures applicable to Dealer.

(j) Registration. Counterparty hereby agrees that if the Shares or Underlying Shares (the Hedge Shares)
acquired by Dealer for the purpose of hedging its obligations pursuant to the Transaction, in Dealers sole judgment, cannot be sold in the U.S. public market (including by depositing such Underlying Shares with the Depository in exchange for
Shares) by Dealer without registration under the Securities Act, Counterparty shall, at its election: (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 to cover the resale of such Hedge Shares and (A) enter into an agreement, in form and substance satisfactory to Dealer and Counterparty, substantially in the form of an underwriting agreement for a registered secondary
offering, (B) provide accountants comfort letters in customary form for registered offerings of equity securities, (C) provide disclosure opinions of nationally recognized outside counsel to Counterparty reasonably
acceptable to Dealer, (D) provide other customary opinions, certificates and closing documents customary in form for registered offerings of equity securities and (E) afford Dealer a reasonable opportunity to conduct a due
diligence investigation with respect to Counterparty customary in scope for underwritten offerings of equity securities; provided 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, subject to the conditions set forth therein, clause (ii) or (iii) of this section 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 Underwriting Agreements customary for
private placements of equity securities, in form and substance satisfactory to Dealer and Counterparty, including 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 Hedge Shares from Dealer), opinions and certificates and such other documentation as is customary for private placements agreements, all reasonably acceptable to Dealer (in which case, the
Calculation Agent shall make any adjustments to the terms of the Transaction that are necessary, in its reasonable judgment, to compensate Dealer for



12



---

any discount from the public market price of the Shares incurred on the sale of Hedge Shares in a private placement); or (iii) to the extent that such purchases would not violate any
applicable law or other restriction applicable to Counterparty, purchase the Hedge Shares from Dealer at the VWAP Price on such Exchange Business Days (with references to Valuation Date in the definition of VWAP Price deemed
to be references to such Exchange Business Days for this purpose), and in such amounts, requested by Dealer. This paragraph (j) shall survive the termination, expiration or early unwind of the Transaction.

(k) Early Unwind. In the event the sale of Convertible Notes for the Transaction (as set forth in the Confirmation for such
Transaction) is not consummated with the initial purchasers for any reason by the close of business in New York City on the Early Unwind Date set forth in the Confirmation for such Transaction, such Transaction shall automatically terminate on such
Early Unwind Date and (i) such Transaction and all of the respective rights and obligations of Dealer and Counterparty under such 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 such Transaction either prior to or after such Early
Unwind Date; provided that, if such failure is due to a breach or default on the part of Counterparty under the Purchase Agreement dated as of March 9, 2011 among CEMEX, S.A.B. de C.V. and Citigroup Global Markets, Inc. and J.P. Morgan
Securities LLC, among others, as representatives of the Initial Purchasers (as defined therein), Counterparty shall assume, or reimburse the cost of, derivatives or other transactions entered into by Dealer or one or more of its
Affiliates in connection with hedging such Transaction. The amount paid by Counterparty shall be Dealers actual cost of such derivatives or other transactions as Dealer informs Counterparty and shall be paid in immediately available funds on
such Early Unwind Date.

(l) Acknowledgment of Pledge. Counterpartys rights under the Agreement may, from time to
time, be pledged to Dealer to secure Counterpartys obligations to Dealer arising under other agreements in accordance with such terms as the parties may separately agree.

(m) Optional Early Termination. (i) At any time during the term of this Transaction, Counterparty may, by written notice to Dealer, designate, with respect to one or more specified Tranches,
an Early Termination Date to occur on the third Scheduled Trading Day following the date such notice is effective, in which case an Additional Termination Event shall be deemed to have occurred in respect of which (1) Counterparty shall be the
sole Affected Party and (2) the portion of the relevant Transaction represented by such Tranche(s) shall be the sole Affected Transaction.

(ii) Counterparty may, prior to electing to terminate any Tranche pursuant to subparagraph (i) above, request a quotation (which may be in the form of a grid of percentages that depends on the price
of the Shares or Underlying Shares over a specified period) from Dealer as to the applicable terms of such termination, and Dealer shall be bound by the terms of such quotation if Counterparty then makes such election within one full Scheduled
Trading Day.

(iii) By providing the notice referred to in this paragraph, Counterparty shall be deemed to
repeat, on the date such notice is effective, the representations in clauses (v), (vi), (vii) and (ix) of Section 11(b).

(n) Counterpartys Obligation to Pay Cancellation Amounts and Early Termination Amounts. Seller and Counterparty hereby agree that, notwithstanding anything to the contrary herein or in the
Agreement, following Sellers receipt from Counterparty of the Premium on the Premium Payment Date, in the event that (a) an Early Termination Date (whether as a result of an Event of Default or a Termination Event) occurs or is designated
with respect to a Transaction and, as a result, Counterparty owes to Seller an amount under Section 6(e) of the Agreement or (b) Counterparty owes to Seller, pursuant to Section 12.7 or Section 12.9 of the Definitions, a
Cancellation Amount, such amount shall be deemed to be zero. If Counterparty pays the Premium on the Premium Payment Date, then under no circumstances shall Counterparty be required to pay any amount in addition to the Premium under the Transaction.
For the avoidance of doubt, the preceding sentence shall not be construed as



13



---

limiting any damages that may be payable by Counterparty as a result of a breach of, or an indemnity under, this Master Confirmation or the Agreement.

(o) Modifications to DR Supplement. The DR Supplement is hereby amended as follows:

(i) The definitions of the following terms in Section 1 thereof are hereby deleted and replaced as follows:

(p) Settlement Amendment. Dealer acknowledges that Counterparty may, to the extent permitted by law and any agreements Counterparty may be subject to, prior to the settlement of any Transaction
hereunder, request that the provisions of this Master Confirmation be modified to enable Counterparty to effect share settlement in lieu of the settlement provisions under Section 5 of this Master Confirmation. In the event of such a request,
Dealer agrees to negotiate with Counterparty, in good faith, such amendments to this Master Confirmation as may be required to effect such changes, it being understood and agreed that as of the date hereof, Counterparty has no right or option to
require share settlement of any Transaction hereunder; provided that Dealer may in good faith refuse to enter into any such amendments so as to comply with applicable legal and regulatory requirements or self-regulatory requirements, or with
related policies and procedures applicable to Dealer.
