The ban shall not cover simultaneous buy and sell orders for the participant's own account if the participant can prove that individual orders were entered independently of each other and without any form of agreement in the exchange system. The participant shall ensure the necessary precautions to prevent impermissible cross-transactions.

3 Trades that are attributable to improper market conduct shall be cancelled by the Exchange or by the participant on the instruction of the Exchange.

13 General provisions

1 Securities trades shall be cleared and settled either with or without the involvement of a central counterparty.

2 The Exchange determines which securities are eligible for clearing via a central counterparty ("CCP-eligible securities").

3 The details are laid down in the "Trading" Directive.

13.1 Execution of trades

1 The transfer and payment of trades must occur two trading days after the trade itself (T+2) ("value date"). Trades via OTE services are governed by the provisions of the clearing and settlement organisations.

2 The exceptions are laid down in the "Trading" Directive.

3 Trades via OTE services are governed by the provisions of the clearing and settlement organisations.

14 Trades not involving a central counterparty

14.1 Contracting parties

A trade shall give rise to a contractual relationship between the participants concerned. The contracting parties shall bear the counterparty risk.

14.2 Content of contract

The contract concluded as described in Clause 14.1 must include the following content, unless the participants concerned conclude other agreements:

14.2.1 Equity securities and investment fund units

1 The rights and obligations (incl. subscription rights, coupons, etc.), as well as all risks attached to the securities sold shall be transferred to the buyer upon conclusion of the contract.

2 Equity securities and investment fund units shall be traded inclusive of the related claims to dividends, capital repayments, subscription rights or other forms of distribution, but exclusive of any outstanding capital that must be paid in ("cum").

SIX Swiss Exchange Ltd 14

Rule Book 01/04/2016

3 As of the ex date, trading in a security shall take place exclusive of any claims to dividends, capital repayments, subscription rights or other forms of distribution ("ex").

4 The ex-day is specified by the issuer. The Exchange publishes the ex date in an appropriate form. It shall offer no warranties and accept no liability in respect of such publication.

14.2.2 Derivatives

1 The rights and obligations as well as all risks attached to the securities sold are transferred to the buyer upon conclusion of the contract.

2 Subscription rights shall be traded separately and may be traded at the latest up to the trading day prior to the end of the exercise period.

14.2.3 Bonds

a) Principle The rights (incl. coupons) and obligations, as well as all risks attached to the securities sold, are transferred to the buyer upon conclusion of the contract. Bonds are traded as a percentage of their par value. The interest accrued on the par value shall be deemed to be the percentage stated in the exchange system, calculated between the date on which the last-paid coupon lapsed and the value date. It must be paid by the buyer in addition to the agreed price. Unless the bond terms state otherwise, the calculation of accrued interest shall, as a rule, be based on the 30/360 method, with February also counted as having 30 days. b) Non-performing bonds Bonds that have either been defaulted on in full, or on whose coupons only a partial distribution has bee paid, shall be traded flat, i.e. without accrued interest. The coupons designated in the exchange system must be transferred with the bonds themselves in such cases. These securities have a special flag in the exchange system. Bonds on which interest is not paid in accordance with the bond terms owing to foreign exchange restrictions, moratoria on transfers or other circumstances, but which have a coupon that may still hold a value, are traded without accrued interest. These securities shall have a special flag in the exchange system as bonds that have a current coupon but for which no accrued interest is calculated. The Exchange may apply different rules in special cases. c) Bonds with differing nominal and coupon currencies Bonds with differing nominal and coupon currencies shall be traded flat on the Exchange, i.e. without accrued interest. The coupons designated in the exchange system must be transferred with the bonds themselves in such cases. These securities have a special flag in the exchange system.

14.2.4 Condition and deliverability of securities

Securities that exist physically and are not transferred by means of book entries must be in good condition and deliverable in accordance with the rules of the settlement organisation concerned.

14.2.5 Material warranty

1 The buyer must immediately check the securities they receive. Should the Buyer identify any defects with regard to their external condition in accordance with Clause 14.2.4, they must submit a complaint to the seller within two trading days of receipt at the latest.

2 The complaint period for other defects runs for thirty days from the effective date of transfer. Complaints in respect of defects that are not identifiable in a routine check may be submitted for one year after the transfer of the securities. The complaint must be made no more than 14 days after the defect is discovered.

SIX Swiss Exchange Ltd 15

Rule Book 01/04/2016

3 Notice of defects given within the set time period shall give rise to a claim to have the defective securities exchanged for units without any defects, but not to any conversion or reduction of the purchase price.

14.2.6 Legal warranty

The Buyer shall continue to be covered by the entitlement to legal warranty of title as described in Article 192 et seq. CO, even if it has not exercised the right of exchange specified under Clause 14.2.5. This claim shall become time-barred after ten years.

14.2.7 Consequences of default

a) Buy-in If a trade cannot be settled on the value date because the selling participant that is in default ("defaulting seller") does not hold the securities, the defaulting seller shall have a further two trading days during which to buy in the missing securities (buy-in on the part of the defaulting seller). The defaulting seller must reimburse the buying participant ("buyer") all direct and indirect costs that it may incur (including costs related to any securities borrowing operation).

If the defaulting seller is not itself able to obtain and deliver the missing securities by no later than noon CET four trading days after the value date (T+6) at the latest, the buyer shall itself be entitled to buy in the same volume of missing securities. The buyer must notify the Exchange and the defaulting seller of its intention to undertake such a buy-in by midnight of the preceding trading day at the latest.

The defaulting seller must bear the costs incurred by the buyer as a result of the buy-in, in particular the difference in price if the price of the securities in question has risen. If the price of the securities has fallen, the defaulting seller shall not have any right to a refund of this difference.

If the buyer's buy-in cannot be effected on day T+6 owing to a lack of trading liquidity in the securities, the buyer shall be entitled to attempt a buy-in for a further 14 trading days, i.e. up to T+20.

Once a buy-in has been affected, the buyer must inform the Exchange and the defaulting seller on the same day, notifying them of the settlement details by fax or electronically. b) Compensation Should the buyer's buy-in attempts fail, the underlying contract between the defaulting seller and buyer shall laps at the close of trading on day T+20 and instead give rise to a compensation claim on the part of the buyer. This compensation claim shall amount to 30% of the contractual purchase price or, if higher, of the closing price on T+20.

14.2.8 Applicable law and arbitration clause

The contract between the participants shall be subject to Swiss law. The jurisdiction is governed by Clause 24.

14.3 Execution

1 Trades that do not involve a central counterparty must be settled via a settlement organisation recognised by the Exchange.

2 The participant shall be responsible for ensuring that settlement instructions for trades that are reported to the Exchange using the trade report function are forwarded to the settlement organisation.

3 The securities must be paid for in the agreed currency.

SIX Swiss Exchange Ltd 16

Rule Book 01/04/2016

15 Trades involving a central counterparty

1 On-order-book trades in CCP-eligible securities shall be cleared and settled via a central counterparty.

2 Trades via OTE services must be cleared and settled via a central counterparty only.

3 Off-order-book trades in CCP-eligible securities shall be cleared and settled via a central counterparty provided the following conditions are met: a) the participants involved in the trade agree that the trade is to be cleared and settled via a central counterparty; and b) the trade is reported to the Exchange using the trade confirmation function and transmitted to the central counterparty during the clearing day defined by the latter.

1 Following an on-order-book trade, the central counterparty shall conclude two separate contracts: one with the buying participant as the seller, and one with the selling participant as the buyer. Under its own terms, the central counterparty may reject the trade or refuse to act as the central counterparty. In such cases, no contract shall be concluded between the participants involved in the trade, and the trade shall become void. No claims may be made against the Exchange or against the other participant.

2 The participants involved in the trade shall not be in a contractual relationship with each other at any time.

3 The "Trading" Directive governs whether or not the identity of the counterparty shall be disclosed to the participants involved in the trade.

15.1.2.1 General provisions

2 An off-order-book trade gives rise to a contract between the participants concerned. This contract remains effective even if the trade is rejected by the central counterparty. Notwithstanding any agreements to the contrary between the Participants, the provisions of Clause 14.2.1 shall apply by analogy in such cases.

15.1.2.2 Exception for the SIX Swiss Exchange Liquidnet Service (SLS)

V Final provisions

20 Confidentiality

1 The Exchange, its governing and executive bodies, employees and agents shall be subject to the professional confidentiality regulations laid down in Art. 147 FMIA.

2 Notwithstanding provisions to the contrary in law or this Rule Book, the Exchange shall treat as confidential all participant-related information that it receives in connection with the Rule Book. The Exchange publishes such confidential information only with the consent of the participant concerned.

3 The use of data which has had identifying information removed (such as price information and the turnover of securities) that does not permit the drawing of any conclusions on the underlying participant, shall not constitute a breach of the confidentiality obligation.

4 The Exchange may disclose data to SIX Group group companies and third parties, such as clearing and settlement organisations, provided the Exchange ensures that these parties are bound by confidentiality provisions that are comparable to those of this Rule Book.

5 Notwithstanding any imperative provisions in law, the Exchange may pass information on participants to supervisory authorities, the surveillance units of other exchanges and enforcement authorities, and may itself obtain information from such authorities.

21 Partial invalidity

In the event that individual provisions of this Rule Book are or become invalid, the validity of the remaining provisions remains unaffected. Should individual provisions of this Rule Book be or become wholly or partially ineffective, they must be interpreted in a way that restores their effectiveness. Where this is not possible, the Exchange shall issue a new rule within a reasonable period and enact it in accordance with the provisions on amendments to this Rule Book.

22 Amendments to the Rule Book

This Rule Book may be amended at any time. Participants shall be notified of such amendments in good time before they take effect. The amendments shall also be published on the Exchange website. The amendments shall be binding on the participant unless the participant rejecting the changes terminates its participation agreement in writing before the amendments enter into force.

23 Binding nature

1 With their admission, the participant shall expressly acknowledge the Rule Book and the Exchange's other regulatory provisions and agree to be bound by them.

2 In the event of any incongruent, the German version of the Rule Book and the Directives takes precedence over any and all other language versions.

24 Applicable law and arbitration clause

1 This Rule Book is subject to the substantive laws of Switzerland. It has been issued in the context of self-regulation activities, as described in Art. 27 FMIA. This choice of law also applies to all of the legal issues referred to in Art. 2 para. 1 of the Hague Securities Convention.

SIX Swiss Exchange Ltd 21

Rule Book 01/04/2016

2 Disputes with SIX Swiss Exchange Ltd and the regulatory bodies (currently: these are Regulatory Board, SIX Exchange Regulation, the Sanction Commisssion and the Appeals Board), in particular those concerning sanctions that have been imposed, shall be decided solely and finally by their Zurich-based arbitration court, and only once internal channels of appeal have been exhausted in accordance with the above legal principles. The arbitration court comprises one chairman and one arbitrator appointed for each party for the case at hand. The chairman and his deputy are appointed by the President of the Swiss Federal Supreme Court for a fouryear term of office. If several parties are plaintiffs or defendants, they agree on one common arbitrator otherwise the corresponding arbitrator will be appointed by the competent court. The chairman may conduct verbal arbitration proceedings. The third part of the Swiss Federal Code of Civil Procedure (Schweizerische Zivilprozessordnung) is applicable to the arbitration proceedings. In any case a possible arbitration code passed by the Regulatory Board supercedes the Swiss Federal Code of Civil Procedure and Chapter 12 of the Federal Statue on Private International Law (Bundesgesetz über das internationale Privatrecht [IPRG], SR 291) is expressly excluded.

25 Transitional provisions

1 Participant admission procedures that are currently ongoing will be handled in accordance with the new provisions.

2 Sanction proceedings that are currently ongoing will be handled in accordance with the old provisions.

3 Sanction proceedings that do not begin until after this Rule Book has entered into force will also be handled in accordance with the old provisions, provided the actions or omissions on which they rest took place under the old law.
