Material United States Federal Income Tax Considerations

The following discussion summarizes material U.S. federal income tax consequences of owning and disposing of the securities that may be relevant to holders of the securities that acquire their securities from us as part of the original issuance of the securities. This discussion applies only to holders that hold their securities as capital assets within the meaning of the Internal Revenue Code of 1986, as amended (the “ Code ”), and that, in the case of securities characterized as debt, purchase the securities at the “issue price” of the securities (as described below). Further, this discussion does not address all of the U.S. federal income tax consequences that may be relevant to you in light of your individual circumstances or if you are subject to special rules, such as if you are:

The discussion is based upon the Code, law, regulations, rulings and decisions, in each case, as available and in effect as of the date hereof, all of which are subject to change, possibly with retroactive effect. Tax consequences under state, local and foreign laws are not addressed herein. No ruling from the IRS has been sought as to the U.S. federal income tax consequences of the ownership and disposition of the securities, and the following discussion is not binding on the IRS.

You should consult your tax advisor as to the specific tax consequences to you of owning and disposing of the securities, including the application of federal, state, local and foreign income and other tax laws based on your particular facts and circumstances.

Characterization of the Securities

There are no statutory provisions, regulations, published rulings or judicial decisions addressing the characterization for U.S. federal income tax purposes of the securities or instruments with terms that are substantially the same as those of your securities. We cannot assure you that the IRS or any court will agree with the tax treatment described below or in the applicable pricing supplement for a particular security. The possible alternative characterizations and risks to investors of such characterizations are discussed below.

The U.S. federal income tax consequences to a U.S. Holder of securities will differ depending on the terms of the securities. As discussed further below, one possible characterization of the securities is that they are treated, for U.S. federal income tax purposes, as prepaid financial contracts with respect to the relevant underlying. Another possibility is that the securities are treated, for U.S. federal income tax purposes, as (1) an option (the “Option”) that requires the holder to settle against the value of the reference underlying and (2) a deposit with us of cash, in an amount equal to the amount paid for a security (the “ Deposit ”) to secure the holder’s potential obligation under the Option. Another possible characterization of the securities is that they are treated, for U.S. federal income tax purposes, as debt. The applicable pricing supplement will specify the treatment of the securities for U.S. federal income tax purposes. In the absence of an administrative or judicial ruling to the contrary, by acceptance of the

securities you agree to treat the securities for all tax purposes in accordance with such characterization and the balance of this discussion assumes that the securities will be so treated.

Alternative Characterizations of the Securities

You should be aware that the characterization of the securities as described above is not certain, nor is it binding on the IRS or the courts. Thus, it is possible that the IRS would seek to characterize your securities in a manner that results in tax consequences to you that are different from those described below. For example, the IRS might characterize a security as a notional principal contract (an “ NPC ”). In general, payments on an NPC are accrued ratably (as ordinary income or deduction, as the case may be) over the period to which they relate regardless of an investor’s usual method of tax accounting. Payments made to terminate an NPC (other than perhaps a final scheduled payment) are capital in nature. Deductions for NPC payments may be limited in certain cases. Certain payments under an NPC may be treated as U.S. source income. Generally, the securities are not, and we do not expect that the securities will be, listed on a securities exchange. In the event the securities are listed on a securities exchange, it is also possible that the IRS would seek to characterize your securities as Code section 1256 contracts. In such case, the securities would be marked-to-market at the end of the year and 40% of any gain or loss would be treated as short-term capital gain or loss, and the remaining 60% of any gain or loss would be treated as long-term capital gain or loss. If the underlying references shares in a non-U.S. company, including American Depository Shares (“ ADSs ”), the IRS could also characterize your security as an option on a passive foreign investment company (“ PFIC ”). Alternatively, the IRS might assert that the securities constitute a “constructive ownership transaction,” in which case, under Code section 1260, all or a portion of your gain, if any, from the securities would be recharacterized as ordinary income, and you would be required to pay additional tax calculated by reference to interest on the tax on such recharacterized income. See “Constructive Ownership Transaction Rules” below. We are not responsible for any adverse consequences that you may experience as a result of any alternative characterization of the securities for U.S. federal income tax or other tax purposes.

You should consult your tax advisor as to the tax consequences of such characterization and any possible alternative characterizations of your securities for U.S. federal income tax purposes.

U.S. Holders

For purposes of this discussion, the term “U.S. Holder,” for U.S. federal income tax purposes, means a beneficial owner of securities that is (1) a citizen or resident of the United States, (2) a corporation (or an entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any state thereof or the District of Columbia, (3) an estate, the income of which is subject to U.S. federal income taxation regardless of its source, or (4) a trust, if (a) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. persons have the authority to control all substantial decisions of the trust or (b) such trust has in effect a valid election to be treated as a domestic trust for U.S. federal income tax purposes. If a partnership (or an entity treated as a partnership for U.S. federal income tax purposes) holds securities, the U.S. federal income tax treatment of such partnership and a partner in such partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partnership, or a partner of a partnership, holding securities, you should consult your tax advisor regarding the tax consequences to you from the partnership’s purchase, ownership and disposition of the securities.

Securities Characterized as Prepaid Financial Contracts

In the case of securities that are characterized as prepaid financial contracts, if the security provides for the payment of one or more coupons, a U.S. Holder will treat any coupon payment received in respect of a security as ordinary income includible in such U.S. Holder’s income in accordance with the U.S. Holder’s method of accounting.

Upon the redemption, sale or other taxable disposition of a security (and subject to the discussion below under “Constructive Ownership Transaction Rules”), a U.S. Holder generally will recognize gain or loss equal to the difference between the amount realized on the sale or other taxable disposition and the U.S. Holder’s tax basis in the security. Such gain or loss will be long-term capital gain or loss in the case of a U.S. Holder that has held the security for more than one year at the time of disposition and short-term capital gain or loss otherwise. It is possible that a portion of the amount realized from the sale or taxable disposition of the securities prior to the payment date attributable to an expected coupon could be treated as ordinary income. You should consult your tax advisor regarding this possibility and the consequences of such treatment to you.

Securities Characterized as an Option and a Deposit

In the case of securities that are characterized as an Option and a Deposit, a U.S. Holder will be subject to the following federal income tax treatment.

A U.S. Holder will treat each coupon as comprised of a component that is stated interest on the security, as specified in the applicable pricing supplement, which should be treated as interest on the Deposit, and the balance of the coupon should be treated as a payment of option premium received by the U.S. Holder in respect of the Option (the “ Option Premium ”). The Option Premium component of each coupon will be treated as an installment payment of the Option Premium for the Option. Any Option Premium paid prior to redemption or maturity of the securities should be treated as short-term capital gain when received.

U.S. Holders should include the interest component of each coupon in income as received or accrued, based on their method of accounting.

At redemption or maturity, a U.S. Holder should be deemed to receive all or a portion of the Deposit and any accrued but unpaid coupons. Any coupons deemed to be received will be taxed as described above. Ordinarily, there should be no gain or loss on the Deposit, and it is assumed that this will be the case. If the amount received at redemption or maturity (excluding any coupon paid at such time) is less than the amount of the Deposit, the Option should be deemed exercised at the time of redemption or maturity, as the case may be. In such a case, the difference between the Deposit and the amount received, less accrued but unpaid interest on the Deposit to which the U.S. Holder is entitled (taxed as described above), is deemed to have been paid to settle the Option. Any loss on the Option, calculated as (a) the Deposit, less (b) the amount received at redemption or maturity (excluding any coupon paid at such time and less accrued but unpaid interest on the Deposit to which the U.S. Holder is entitled) plus the Option Premium (excluding any Option Premium that has been included in income), should be short-term capital loss. If the amount paid at redemption or maturity is equal to the Deposit (excluding any coupon paid at such time), the Option should be deemed to have expired unexercised and an amount equal to any accrued but unpaid Option Premium should be treated as short-term capital gain. The interest portion of any coupon should be taxed as described above.

Upon a sale or exchange of a security, a U.S. Holder should allocate the sale proceeds received between the Deposit and the Option on the basis of their respective fair market values on the date of sale. The U.S. Holder should generally recognize gain or loss with respect to the Deposit in an amount equal to the difference between the amount of the sale proceeds allocable to the Deposit (less accrued but unpaid interest on the Deposit which will be taxed as described above) and the U.S. Holder’s adjusted tax basis in the Deposit (which generally will equal the issue price of the security). Generally, there should be no gain or loss with respect to the Deposit. A U.S. Holder should generally recognize gain or loss with respect to the Option in an amount equal to the difference between the amount of the sale proceeds allocable to the Option and the U.S. Holder’s adjusted tax basis in the Option. If the value of the total sale proceeds received (minus accrued but unpaid interest with respect to the Deposit) exceeds the Deposit, then the U.S. Holder should recognize short-term capital gain equal to the amount of remaining sale proceeds allocable to the Option. If the value of the Deposit exceeds the total sale proceeds received (minus accrued but unpaid interest with respect to the Deposit), then the U.S. Holder should be treated as having paid the buyer an amount equal to the amount of such excess in exchange for the buyer’s assumption of the U.S. Holder’s rights and obligations under the Option (such excess being referred to as “ Deemed Payment ”). In such a case, the U.S. Holder

should recognize short-term capital loss in an amount equal to the Deemed Payment made by the U.S. Holder to the buyer with respect to the assumption of the Option.

Securities Characterized as Debt

In some cases, U.S. Holders should treat the securities as debt instruments that are subject to the regulations governing contingent debt instruments (“ Contingent Debt Regulations ”) if they have a term of more than one year. Under the Contingent Debt Regulations, actual cash payments on the securities, if any, will not be reported separately as taxable income, but will be taken into account under such regulations. As discussed more fully below, the effect of the Contingent Debt Regulations will be to:

A U.S. Holder will be required to accrue an amount of original issue discount for U.S. federal income tax purposes, for each accrual period prior to and including the maturity date of the securities, that equals:

The “issue price” of a security will be the first price at which a substantial amount of the securities is sold to the public, excluding bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. The adjusted issue price of a security will be its issue price increased by any original issue discount previously accrued, determined without regard to any adjustments to original issue discount accruals described below, and decreased by the amount of any noncontingent payment and the projected amounts of any payments previously made with respect to the securities.

Under the Contingent Debt Regulations, a U.S. Holder will be required to include original issue discount in income each year, regardless of such holder’s usual method of tax accounting, based on the comparable yield of the securities. We will determine the comparable yield of the securities based on the rate, as of the initial issue date, at which we would issue a fixed rate debt instrument with no contingent payments but with terms and conditions similar to the securities. We are required to furnish holders the comparable yield and, solely for tax purposes, a projected payment schedule that estimates the amount and timing of contingent interest payments. For purposes of this determination—and only for purposes of this determination, which is required for U.S. federal income tax purposes—we have assumed that the securities will not be called and will be held until the maturity date.

The pricing supplement may include information regarding the comparable yield and projected payment schedule, or U.S. Holders can obtain this information by contacting Credit Suisse Tax Department, One Madison Avenue, Fourth Floor, New York, New York, 10010.

If the actual contingent payment received differs from the projected payment, adjustments will be made for the difference. If such payment exceeds the projected payment, a U.S. Holder will incur a positive adjustment equal to the amount of such excess. Such positive adjustment will be treated as additional original issue discount in such taxable year. If, however, such payment is less than the amount of the projected payment, the U.S. Holder will incur a negative adjustment equal to the amount of such deficit. A negative adjustment will:

A net negative adjustment is not subject to the two percent floor limitation imposed on miscellaneous itemized deductions under Code section 67.

Upon the sale or other taxable disposition of a security, a U.S. Holder will recognize gain or loss equal to the difference between such holder’s amount realized and the holder’s adjusted tax basis in the security. Any gain on a security generally will be treated as ordinary income. Loss from the disposition of a security will be treated as ordinary loss to the extent of the U.S. Holder’s prior net original issue discount inclusions with respect to the securities. Any loss in excess of that amount will be treated as capital loss, which generally will be long-term if the securities were held for more than one year. The deductibility of net capital losses by individuals and corporations are subject to limitations.

Special rules apply in determining the tax basis of a security. A U.S. Holder’s adjusted tax basis in a security is generally such holder’s original purchase price for the security increased by original issue discount (before taking into account any adjustments) such holder previously accrued on the securities and reduced by the amount of any noncontingent payment and the projected amount of any contingent payments previously scheduled to be made to such holder (without regard to the actual amount paid).

If the securities have a term of one year or less, the rules for short-term debt obligations would apply rather than the Contingent Debt Regulations. Under Treasury regulations, a short-term debt obligation is treated as issued at a discount equal to the excess of the sum of all payments provided by the obligation over the obligation’s issue price. It is unclear how the rules governing short-term debt obligations apply to short-term debt obligations that have contingent payments, such as may be the case with the securities.

Under the rules that apply to short term debt obligations, a cash method U.S. Holder (other than an Electing Cash-method U.S. Holder, as defined below) should include any discount on the securities as ordinary income upon receipt. Upon a sale or other taxable disposition of a security, a cash method U.S. Holder (other than an Electing Cash-method U.S. Holder) should recognize gain or loss with respect to the security in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in the security. Such gain or loss will be short-term capital gain or loss, except to the extent of the discount that has accrued on a straight-line basis (or, if elected, according to a constant-yield method based on daily compounding) through the date of the sale or other taxable disposition, which should be treated as ordinary income. In addition, a cash method U.S. Holder (other than an Electing Cash-method U.S. Holder) will be required to defer deductions for any interest paid on indebtedness incurred to purchase or carry the security until it is included in income.

Under the rules that apply to short term debt obligations, an accrual method, a cash method U.S. Holder that elects to accrue the discount currently (an “Electing Cash-method U.S. Holder”), or certain specified taxpayers (e.g., regulated investment companies) should include any discount on the securities as ordinary income as it accrues on a straight-line basis, unless it elects to accrue the discount on a constant yield method based on daily compounding. Upon a sale or other taxable disposition of a security, such a U.S. Holder should recognize gain or loss with respect to the security in an amount equal to the difference between the amount realized and the U.S. Holder’s adjusted tax basis in the security. Such gain or loss will be short-term capital gain or loss, except to the extent of any discount that has accrued on a straight-line basis (or, if elected, according to a constant-yield method based on daily compounding) through the date of the sale or other taxable disposition and has not previously been included in income, which should be treated as ordinary income.

It is uncertain whether the coupons should be treated as interest income includible in a U.S. Holder’s income in accordance with such U.S. Holder’s method of accounting (e.g., upon receipt, in the case of a cash

method U.S. Holder), or treated as part of the redemption payment at maturity. In view of this uncertainty, we intend to treat all coupons on the securities as ordinary income when paid by us. Where a security provides for contingent payments, it is also unclear whether a U.S. Holder would be eligible to amortize a portion of the purchase price as bond premium, if any.

You should consult your tax advisor regarding the possible tax consequences of characterization of the securities as contingent payment debt instruments or short-term debt obligations.

Constructive Ownership Transaction Rules

All or a portion of gain arising from certain “constructive ownership transactions” may be recharacterized as ordinary income, and certain interest charges may be imposed with respect to any such recharacterized income. These rules by their terms may apply to any gain derived from the securities if the securities reference an equity interest in a “pass-thru entity” within the meaning of Code section 1260, which includes shares in a PFIC, an exchange traded fund, and certain other entities. If the term of the securities is one year or greater and the underlying references an equity interest in a non-U.S. company, including ADSs, or an exchange traded fund, the IRS might assert that the constructive ownership transaction rules of Code section 1260 apply.

If the securities are treated as a constructive ownership transaction, any gain therefrom that otherwise would be long-term capital gain in excess of the “net underlying long-term capital gain” will be treated as ordinary income, and an interest charge will apply as if such income had accrued for tax purposes at a constant yield over the term of the securities. There is a presumption that all of the gain realized that otherwise would have been long-term capital gain is subject to recharacterization as ordinary income and an interest charge, unless the contrary is demonstrated by clear and convincing evidence. Accordingly, any gain a U.S. Holder realizes from the sale, exchange or redemption of its securities in excess of the amount of long-term capital gain that it can establish that it would have realized had it (1) invested in the underlying (rather than the securities) on the issue date of the securities, and (2) sold the underlying on the date of sale, exchange or redemption of the securities, could be recharacterized as ordinary income and subject to an interest charge, as described above.

Code section 1260 also provides that the U.S. Department of the Treasury is to issue regulations that would exclude from the scope of Code section 1260 certain forward contracts that do not convey “substantially all of the economic return” with respect to the applicable reference asset, which in the case of the securities would be all or a portion of the underlying. However, no such regulations have been issued despite the fact that Code section 1260 was enacted in 1999, and there can be no assurance that any regulations that may be issued would apply to securities that are issued before such regulations. In the absence of regulations, there can be no assurance that the securities would not be so considered or that Code section 1260 would not otherwise apply to the securities.

You should consult with your tax advisor regarding the possible application of the constructive ownership transaction rules to the securities.

Medicare Tax

Certain U.S. Holders that are individuals, estates, and trusts must pay a 3.8% tax (the “ Medicare Tax ”) on the lesser of the U.S. Holder’s (1) “net investment income” or “undistributed net investment income” in the case of an estate or trust and (2) the excess of modified adjusted gross income over a certain specified threshold for the taxable year. “Net investment income” generally includes income from interest, dividends, and net gains from the disposition of property (such as the securities) unless such income or net gains are derived in the ordinary course of a trade or business (other than a trade or business that is a passive activity with respect to the taxpayer or a trade or business of trading in financial instruments or commodities). Net investment income may be reduced by allowable deductions properly allocable to such gross income or net gain. Any interest earned or deemed earned on the securities and any gain on sale or other taxable disposition of the securities will be subject to the Medicare Tax. If you are an individual, estate, or trust, you should consult with your tax advisor regarding application of the Medicare Tax to your income and gains in respect of your investment in the securities.

Securities Held Through Foreign Entities

Under certain provisions of the “Hiring Incentives to Restore Employment Act,” generally referred to as “FATCA,” and regulations thereunder, a 30% withholding tax is imposed on “withholdable payments” and certain “passthru payments” made to “foreign financial institutions” (as defined in the regulations or an applicable intergovernmental agreement) (and their more than 50% affiliates) unless the payee foreign financial institution agrees, among other things, to disclose the identity of any U.S. individual with an account at the institution (or the institution’s affiliates) and to annually report certain information about such account. The term “withholdable payments” generally includes (1) payments of fixed or determinable annual or periodical gains, profits, and income (“ FDAP ”), in each case, from sources within the United States, and (2) gross proceeds from the sale of any property of a type which can produce interest or dividends from sources within the United States. “Passthru payments” means any withholdable payment and any foreign passthru payment. To avoid becoming subject to the 30% withholding tax on payments to it, a financial institution may be required to report information to the IRS regarding the holders of the securities. In the case of holders who (i) fail to provide the relevant information, (ii) are foreign financial institutions who have not agreed to comply with these information reporting requirements, or (iii) hold the securities directly or indirectly through such non-compliant foreign financial institutions, a payor may be required to withhold on a portion of payments under the securities. FATCA also requires withholding agents making withholdable payments to certain foreign entities that do not disclose the name, address, and taxpayer identification number of any substantial U.S. owners (or certify that they do not have any substantial U.S. owners) to withhold tax at a rate of 30%. If payments on the securities are determined to be from sources within the United States, such payments will be treated as withholdable payments for these purposes.

Withholding under FATCA will apply to all withholdable payments and certain passthru payments without regard to whether the beneficial owner of the payment is a U.S. person, or would otherwise be entitled to an exemption from the imposition of withholding tax pursuant to an applicable tax treaty with the United States or pursuant to U.S. domestic law. Unless a foreign financial institution is the beneficial owner of a payment, it will be subject to refund or credit in accordance with the same procedures and limitations applicable to other taxes withheld on FDAP payments provided that the beneficial owner of the payment furnishes such information as the IRS determines is necessary to determine whether such beneficial owner is a U.S.-owned foreign entity and the identity of any substantial U.S. owners of such entity. If such withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld.

Subject to the exceptions described below, FATCA’s withholding regime generally will apply to (i) withholdable payments (other than gross proceeds of the type described above and certain payments made with respect to a “preexisting obligation,” as defined in the regulations), (ii) payments of gross proceeds of the type described above with respect to a sale or disposition occurring after December 31, 2018, and (iii) foreign passthru payments made after the later of December 31, 2018, or the date that final regulations defining the term “foreign passthru payment” are published. Notwithstanding the foregoing, the provisions of FATCA discussed above generally will not apply to (a) with respect to foreign passthru payments, any obligation (other than an instrument that is treated as equity for U.S. tax purposes or that lacks a stated expiration or term) that is executed on or prior to the date that is six months after the date on which final regulations defining foreign passthru payments are published (a “ grandfathered obligation ”), (b) any obligation that produces withholdable payments solely because the obligation is treated as giving rise to a dividend equivalent pursuant to Code section 871(m) and the regulations thereunder that is executed on or prior to the date that is six months after the date on which obligations of its type are first treated as giving rise to dividend equivalents, and (c) any agreement requiring a secured party to make payments with respect to collateral securing one or more grandfathered obligations (even if the collateral is not itself a grandfathered obligation). Thus, if you hold your securities through a foreign financial institution or foreign entity, a portion of any of your payments may be subject to 30% withholding.

Information Reporting Regarding Specified Foreign Financial Assets

The Code and regulations thereunder generally require individual U.S. Holders (“ specified individuals ”) and “specified domestic entities” with an interest in any “specified foreign financial asset” to file an annual report on IRS Form 8938 with information relating to the asset, including the maximum value thereof, for any taxable year in

which the aggregate value of all such assets exceeds $50,000 on the last day of the taxable year or $75,000 at any time during the taxable year. Certain individuals are permitted to have an interest in a higher aggregate value of such assets before being required to file a report. Specified foreign financial assets include, with some limited exceptions, any financial account maintained at a foreign financial institution and any debt or equity interest in a foreign financial institution, including a financial institution organized under the laws of a U.S. possession, and any of the following that are held for investment and not held in an account maintained by a financial institution: (1) any stock or security issued by a person other than a U.S. person (including a person organized in a U.S. possession), (2) any financial instrument or contract that has an issuer or counterparty that is other than a U.S. person (including a person organized in a U.S. possession), and (3) any interest in a foreign entity. Additionally, the regulations provide that specified foreign financial assets include certain retirement and pension accounts and non-retirement savings accounts.

Pursuant to the regulations and subject to certain exceptions, “specified domestic entities” are domestic corporations, domestic partnerships, or certain trusts that are formed or used for the purposes of holding, directly or indirectly, specified foreign financial assets. Generally, specified domestic entities are certain corporations and partnerships, which are closely held by a specified individual and that meet passive income or passive asset tests, and, with certain exceptions, domestic trusts that have one or more specified individuals or specified domestic entities as a current beneficiary.

Depending on the aggregate value of your investment in specified foreign financial assets, you may be obligated to file an IRS Form 8938 under this provision if you are an individual U.S. Holder or a specified domestic entity. Penalties apply to any failure to file IRS Form 8938. In the event a U.S. Holder (either a specified individual or specified domestic entity) does not file such form, the statute of limitations on the assessment and collection of U.S. federal income taxes of such U.S. Holder for the related tax year may not close before the date which is three years after the date such information is filed. You should consult your tax advisor as to the possible application to you of this information reporting requirement and the related statute of limitations tolling provision.

Non-U.S. Holders Generally

If the securities are not characterized as debt and provide for the payment of one or more coupons, the U.S. federal income tax treatment of such coupon payments is unclear. In such case, except as provided under “Securities Held Through Foreign Entities” and “Substitute Dividend and Dividend Equivalent Payments” and unless otherwise stated in the applicable pricing supplement, we currently do not intend to withhold any tax on any coupon payments made to a holder of the securities that is not a U.S. Holder (a “ Non-U.S. Holder ”) and that has no connection with the United States other than holding its securities, provided that such Non-U.S. Holder complies with applicable certification requirements. However, it is possible that the IRS could assert that such payments are subject to U.S. withholding tax, or that we or another withholding agent may otherwise determine that withholding is required, in which case we or the other withholding agent may withhold up to 30% on such payments (subject to reduction or elimination of such withholding tax pursuant to an applicable income tax treaty). We will not pay any additional amounts in respect of such withholding. Except as provided under “Securities Held Through Foreign Entities” and “Substitute Dividend and Dividend Equivalent Payments,” payment of the redemption amount by us in respect to the securities (except to the extent of the coupons) to a Non-U.S. Holder that has no connection with the United States other than holding its securities will not be subject to U.S. withholding tax, provided that such Non-U.S. Holder complies with applicable certification requirements.

If the securities are characterized as debt, except as provided under “Securities Held Through Foreign Entities” and “Substitute Dividend and Dividend Equivalent Payments” and unless otherwise stated in the applicable pricing supplement, payments made with respect to the securities to a holder of the securities that is not a U.S. Holder (a “ Non-U.S. Holder ”) and that has no connection with the United States other than holding its securities will not be subject to U.S. withholding tax provided that such Non-U.S. Holder complies with applicable certification requirements.

Any gain realized upon the sale or other disposition of the securities by a Non-U.S. Holder generally will not be subject to U.S. federal income tax unless (1) such gain is effectively connected with a U.S. trade or business

of such Non-U.S. Holder or (2) in the case of an individual, such individual is present in the United States for 183 days or more in the taxable year of the sale or other disposition and certain other conditions are met. Any effectively connected gains described in clause (1) above realized by a Non-U.S. Holder that is, or is taxable as, a corporation for U.S. federal income tax purposes may also, under certain circumstances, be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty.

Non-U.S. Holders that are subject to U.S. federal income taxation on a net income basis with respect to their investment in the securities should refer to the discussion above relating to U.S. Holders.

Substitute Dividend and Dividend Equivalent Payments

The Code and regulations thereunder treat a “dividend equivalent” payment as a dividend from sources within the United States. Unless reduced by an applicable tax treaty with the United States, such payments generally will be subject to U.S. withholding tax at a rate of 30%. A “dividend equivalent” payment is defined under the Code as (i) a substitute dividend payment made pursuant to a securities lending or a sale-repurchase transaction that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, (ii) a payment made pursuant to a “specified notional principal contract” (a “ specified NPC ”) that (directly or indirectly) is contingent upon, or determined by reference to, the payment of a dividend from sources within the United States, and (iii) any other payment determined by the IRS to be substantially similar to a payment described in the preceding clauses (i) and (ii).

Regulations provide that a dividend equivalent is any payment that references the payment or deemed payment of (i) a dividend from an underlying security pursuant to a securities lending or sale-repurchase transaction, (ii) a dividend from an underlying security pursuant to a specified NPC, (iii) a dividend from an underlying security pursuant to a specified equity-linked instrument (a “ specified ELI ”), and (iv) any other substantially similar payment. The regulations provide that a payment includes a dividend equivalent payment whether there is an explicit or implicit reference to a dividend with respect to the underlying security. An underlying security is any interest in an entity if a payment with respect to that interest could give rise to a U.S. source dividend pursuant to Treasury regulation section 1.861-3. An NPC is a notional principal contract as defined in Treasury regulation section 1.446-3(c). An equity-linked instrument (“ ELI ”) is a financial instrument (other than a securities lending or sale-repurchase transaction or an NPC) that references the value of one or more underlying securities, including a futures contract, forward contract, option, debt instrument, or other contractual arrangement. A “section 871(m) transaction” is any securities lending or sale-repurchase transaction, specified NPC, or specified ELI.

Pursuant to the regulations, for any payment made on or after January 1, 2017 with respect to any transaction issued on or after January 1, 2017, any NPC or ELI that has a delta of one with respect to an underlying security when the NPC or ELI is issued is a specified NPC or specified ELI, respectively. For any payment made on or after January 1, 2018 with respect to any transaction issued on or after January 1, 2018, (a) a “simple” NPC or “simple” ELI that has a delta of 0.8 or greater with respect to an underlying security when the NPC or ELI is issued is a specified NPC or specified ELI, respectively, and (b) a “complex” NPC or “complex” ELI that meets a substantial equivalence test with respect to an underlying security at the time of issuance is a specified NPC or specified ELI, respectively.

Certain events could cause previously issued securities to be deemed to be issued as new securities for purposes of the effective dates provided in the regulations. For example, it is possible that the IRS could assert that a reconstitution or rebalancing of the underlying is a significant modification of the securities due to an exercise of discretion with respect to such reconstitution or rebalancing and, therefore, a deemed issuance of the securities upon the occurrence of such event. It is also possible that U.S. withholding tax could apply to the securities under these rules if a Non-U.S. Holder enters, or has entered, into certain other transactions in respect of the underlying equity or the securities. A Non-U.S. Holder that enters, or has entered, into other transactions in respect of the underlying or the securities should consult its own tax advisor regarding the application of Code section 871(m) to its securities in the context of its other transactions.

Withholding on payments will be based on actual dividends or, if otherwise notified by us in accordance with applicable regulations, on estimated dividends used in pricing the security. If an adjustment is made for the actual dividends, then the true-up payment (in addition to the estimated dividend) is added to the per-share dividend amount. If a transaction is a section 871(m) transaction, information regarding the amount of each dividend equivalent, the delta of the potential 871(m) transaction, the amount of any tax withheld and deposited, the estimated dividend amount and any other information necessary to apply the regulations will be provided, communicated, or made available to Non-U.S. Holders in a manner permitted by the applicable regulations.

In accordance with the regulations, U.S. tax will be withheld on any portion of a payment or deemed payment (including, if appropriate, the payment of the purchase price) that is a dividend equivalent with respect to any security unless reduced by an applicable tax treaty and a properly executed IRS Form W-8 (or other qualifying documentation) is provided. If withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld. These regulations are extremely complex. Non-U.S. Holders should consult their tax advisors regarding the U.S. federal income tax consequences to them of these regulations and whether payments or deemed payments on the securities constitute dividend equivalent payments.

Foreign Investment in U.S. Real Property

A Non-U.S. Holder may be subject to U.S. federal income tax on a disposition of a “U.S. real property interest” as defined in Treasury Regulations section 1.897-1(c) (a “ USRPI ”). Any gain on such disposition is treated as effectively connected with a U.S. trade or business of the Non-U.S. Holder and is subject to tax and withholding on the amount realized on the disposition. A USRPI may consist of an interest in U.S. real property or an interest in a United States real property holding corporation (a “ USRPHC ”) within the meaning of Code section 897. However, an interest in a USRPHC that does not exceed generally 5% of the corporation’s regularly traded stock is not a USRPI.

Thus, a Non-U.S. Holder who owns directly, indirectly or constructively, shares of any underlying that is considered to be a USRPI, or other interests having a return based on the appreciation in the value of, or in the gross or net proceeds or profits generated by, such underlying, may be subject to U.S. federal income tax on the sale or exchange of the securities if such Non-U.S. Holder owns more than generally 5% of the shares of such underlying when considering the shares or other interests of such underlying that are directly, indirectly or constructively owned by such Non-U.S. Holder. Ownership of the securities may also impact the taxation of such other shares or interests.

We do not intend to ascertain whether the issuer of shares in any underlying is a USRPHC. In making its investment decision, a Non-U.S. Holder should be prepared to accept the tax treatment that results from either the underlying being treated as a USRPI or from the underlying not being a USRPI.

Each Non-U.S. Holder, in connection with acquiring the securities, is deemed to represent that it does not own, and will not own, more than 5% of the shares of each of the underlying that is considered to be a USRPHC, either directly, indirectly or constructively. We and any withholding agent will rely on the accuracy of this representation. For purposes of this discussion, any interest other than solely as a creditor within the meaning of Treasury Regulations Section 1.897-1(d) shall be treated as ownership of shares of the underlying.

Non-U.S. Holders should consult their own tax advisors on the impact of other shares or interests in the underlying, the impact of ownership of the securities on such other shares or interests, and the consequences of making the representation in the preceding paragraph.

U.S. Federal Estate Tax Treatment of Non-U.S. Holders

A security may be subject to U.S. federal estate tax if an individual Non-U.S. Holder holds the security at the time of his or her death. The gross estate of a Non-U.S. Holder domiciled outside the United States includes only property situated in the United States. Individual Non-U.S. Holders should consult their tax advisors regarding the U.S. federal estate tax consequences of holding the securities at death.

Potential Changes to the Tax Rules for Financial Instruments

Members of Congress have from time to time proposed legislation relating to financial instruments, including legislation that would require holders to annually mark to market affected financial instruments (potentially including the securities). These or other potential changes in law could adversely affect the tax treatment of the securities and may be applied with retroactive effect. You are urged to consult your tax advisor regarding how any such potential changes in law could affect you.

Backup Withholding and Information Reporting

A holder of the securities (whether a U.S. Holder or a Non-U.S. Holder) may be subject to backup withholding with respect to certain amounts paid to such holder unless it provides a correct taxpayer identification number, complies with certain certification procedures establishing that it is not a U.S. Holder or establishes proof of another applicable exemption, and otherwise complies with applicable requirements of the backup withholding rules. Backup withholding is not an additional tax. You can claim a credit against your U.S. federal income tax liability for amounts withheld under the backup withholding rules, and amounts in excess of your liability are refundable if you provide the required information to the IRS in a timely fashion. A holder of the securities may also be subject to information reporting to the IRS with respect to certain amounts paid to such holder unless it (1) is a Non-U.S. Holder and provides a properly executed IRS Form W-8 (or other qualifying documentation) or (2) otherwise establishes a basis for exemption. If such withholding applies, we will not be required to pay any additional amounts with respect to amounts withheld.

ERISA Considerations

The Employee Retirement Income Security Act of 1974, as amended (“ ERISA ”), and Section 4975 of the Code, impose certain requirements on (a) employee benefit plans subject to Title I of ERISA, (b) individual retirement accounts, Keogh plans or other arrangements subject to Section 4975 of the Code, (c) entities whose underlying assets include “plan assets” (within the meaning of U.S. Department of Labor Regulation Section 2510.3–101, as modified by Section 3(42) of ERISA) by reason of any such plan’s or arrangement’s investment therein (we refer to the foregoing collectively as “ Plans ”) and (d) persons who are fiduciaries with respect to Plans. In addition, certain governmental, church and non-U.S. plans (“ Non - ERISA Arrangements ”) are not subject to Section 406 of ERISA or Section 4975 of the Code, but may be subject to other laws that are substantially similar to those provisions (each, a “ Similar Law ”).

In considering an investment in the securities of a portion of the assets of any Plan, a fiduciary should determine whether the investment is in accordance with the documents and instruments governing the Plan and the applicable provisions of ERISA, the Code or any Similar Law relating to a fiduciary’s duties to the Plan including, without limitation, the prudence, diversification, delegation of control and prohibited transaction provisions of ERISA, the Code and any other applicable Similar Laws. Fiduciaries of any Plans and Non-ERISA Arrangements should consult their own legal counsel before purchasing the securities.

In addition to ERISA’s general fiduciary standards, Section 406 of ERISA and Section 4975 of the Code prohibit certain transactions involving the assets of a Plan and persons who have specified relationships to the Plan, i . e ., “parties in interest” as defined in ERISA or “disqualified persons” as defined in Section 4975 of the Code (we refer to the foregoing collectively as “ parties in interest ”) unless exemptive relief is available under an exemption issued by the U.S. Department of Labor. Parties in interest that engage in a non-exempt prohibited transaction may be subject to excise taxes and other penalties and liabilities under ERISA and Section 4975 of the Code. We, and our current and future affiliates, including CSSU and the calculation agent, may be parties in interest with respect to many Plans. Thus, a Plan fiduciary considering an investment in the securities should also consider whether such an investment might constitute or give rise to a prohibited transaction under ERISA or Section 4975 of the Code. For example, the securities may be deemed to represent a direct or indirect sale of property, extension of credit or furnishing of services between us and an investing Plan which would be prohibited if we are a party in interest with respect to the Plan unless exemptive relief were available under an applicable exemption.

In this regard, each prospective purchaser that is, or is acting on behalf of, a Plan, and proposes to purchase the securities, should consider the exemptive relief available under the following prohibited transaction class exemptions, or PTCEs: (A) the in-house asset manager exemption (PTCE 96–23), (B) the insurance company general account exemption (PTCE 95–60), (C) the bank collective investment fund exemption (PTCE 91–38), (D) the insurance company pooled separate account exemption (PTCE 90–1) and (E) the qualified professional asset manager exemption (PTCE 84–14). In addition, ERISA Section 408(b)(17) and Section 4975(d)(20) of the Code provide a limited exemption for the purchase and sale of securities and related lending transactions, provided that neither the issuer of the securities nor any of its affiliates have or exercise any discretionary authority or control or render any investment advice with respect to the assets of any Plan involved in the transaction and provided further that the Plan pays no more, and receives no less, than adequate consideration (within the meaning of Section 408(b)(17) of ERISA or Section 4975(f)(10) of the Code) in connection with the transaction (the so-called “ service provider exemption ”). There can be no assurance that any of these statutory or class exemptions will be available with respect to transactions involving the securities.

Each purchaser or holder of the securities, and each fiduciary who causes any entity to purchase or hold the securities, shall be deemed to have represented and warranted, on each day such purchaser or holder holds such securities, that either (i) it is neither a Plan nor a Non-ERISA Arrangement and it is not purchasing or holding the securities on behalf of or with the assets of any Plan or Non-ERISA Arrangement; or (ii) its purchase, holding and subsequent disposition of such securities shall not constitute or result in a non-exempt prohibited transaction under Section 406 of ERISA, Section 4975 of the Code or any provision of Similar Law.

In addition, any purchaser, that is a Plan or that is acquiring the securities on behalf of a Plan, including any fiduciary purchasing on behalf of a Plan, will be deemed to have represented, in its corporate and its fiduciary

capacity, by its purchase and holding of the securities that (a) none of Credit Suisse, the calculation agent or any of their respective affiliates (each, a “ Seller ”) is a “fiduciary” (under Section 3(21) of ERISA, or under any final or proposed regulations thereunder, or with respect to a non-ERISA Arrangement under Similar Law) with respect to the acquisition, holding or disposition of the securities, or as a result of any exercise by us or our affiliates of any rights in connection with the securities, (b) no advice provided by us or any of our affiliates has formed a primary basis for any investment decision by or on behalf of such purchaser in connection with the securities and the transactions contemplated with respect to the securities, and (c) such purchaser recognizes and agrees that any communication from us or any of our affiliates to the purchaser with respect to the securities is not intended by us or any of our affiliates to be impartial investment advice and is rendered in its capacity as a seller of such securities and not a fiduciary to such purchaser. Purchasers of the securities have exclusive responsibility for ensuring that their purchase, holding, and disposition of the securities do not violate the prohibited transaction rules of ERISA or the Code or any similar regulations applicable to governmental or church plans, as described above.

Each purchaser of a security will have exclusive responsibility for ensuring that its purchase, holding and subsequent disposition of the security does not violate the fiduciary or prohibited transaction rules of ERISA, the Code or any Similar Law. Nothing herein shall be construed as a representation that an investment in the securities would meet any or all of the relevant legal requirements with respect to investments by, or is appropriate for, Plans or Non-ERISA Arrangements generally or any particular Plan or Non-ERISA Arrangement.
