NOW, THEREFORE, in consideration of the foregoing, the Parties hereby agree as follows:

§ 1

2.2 The Managing Shareholders in their capacity as managing directors of the Company shall submit audited accounts for the Company to the Non-Managing Shareholder by the end of the third month following the end of the relevant fiscal year.

2.3 The Parties acknowledge that the Non-Managing Shareholder has certain internal information and reporting requirements which it needs the managing directors to adhere to and which are subject to changes. The Managing Shareholders shall, acting reasonably, fulfil such information and reporting requirements. The Parties agree that the Company shall have only the reporting obligations vis-à-vis the Non-Managing Shareholder as set out under the Rules of Procedure, which reporting obligations shall not be substantially increased (unless required by mandatory applicable law, regulations and/or accounting standards), but be subject to reasonably required changes made by the Non-Managing Shareholder upon 30 days notice to the Managing Shareholders’ Representative.

2.4 The Non-Managing Shareholder will introduce the Managing Shareholders and employees of the Company to the reporting requirements of the Non-Managing Shareholder’s group by providing reasonable on-site training and support with respect to technical and IT matters in order for such reporting to be implemented in the Company. The reporting requirements pursuant to § 2.3 of this Agreement shall become obligatory at the earliest four weeks after the above mentioned training and support services have commenced.

§ 3

Transfer of Shares

3.1 To the extent not expressly provided otherwise in this Agreement, any transfer (Verfügung) of shares in the Company (including by way of merger or otherwise), any encumbrance of shares or rights in shares of the Company, including trust and/or sub-participation structures, and entering into contractual obligations to transfer, encumber or make other dispositions to a similar economic effect or make otherwise dispositions over shares in the Company, may not be effected by either Party unless certain prerequisites, as set out under Annex 3.1 hereto, are satisfied.

3.2 The restrictions under § 3.1 shall also apply to transfers of shares in companies of which the only material assets are shares in the Company. The transferring Party will ensure that this provision is complied with in such circumstances.

3.3 Nothing in § 3 of this Agreement shall prohibit the Non-Managing Shareholder from pledging shares in the Company to be in compliance with its general financing contracts from time to time.

3.4 The Parties shall ensure that any transfer of shares in the Company to a third party is subject to the condition precedent that such third party accedes to this Agreement and assumes all liabilities and obligations of the selling

Page 8

The Parties hereby offer to any future shareholder of the Company to accede to this Agreement.

3.6 Nothing in § 3 of this Agreement shall prohibit the Parties from transferring their entire shareholding in the Company directly or indirectly (pursuant to § 3.2) to an affiliated company pursuant to §§ 15 et seq. German Stock Corporation Act (AktG). The relevant transferor shall ensure that any such share transfer to an affiliated company pursuant to §§ 15 et seq. German Stock Corporation Act (AktG) shall be rescinded (zurückübertragen) before such affiliated company ceases to be an affiliated company pursuant to §§ 15 et seq. German Stock Corporation Act (AktG) to the respective Party.

3.7 The Parties shall give all declarations and take all actions which are necessary or beneficial for implementing a sale and transfer of shares in the Company to the extent permitted under this § 3. If not provided otherwise in this Agreement, in all other cases the Parties shall be free to give or refuse to give a consent necessary for a transfer of shares under the Company’s articles of association.

3.8 If a transfer of shares is effected by way of heritage (Gesamtrechtsnachfolge im Erbgang), any such transferee or transferees, as the case may be, should accede to this Agreement and assume all rights, liabilities and obligations of the deceased shareholder. Such accession and assumption shall be declared to the remaining shareholders of the Company under a notarial deed. The Parties hereby offer to any future shareholder of the Company to accede to this Agreement. If such transferee does not accede to this Agreement within three (3) months following the death of the relevant shareholder, such shares may be redeemed by the Company pursuant to its articles of association.

5.2 The Parties shall give all declarations and take all actions which are necessary or beneficial for implementing the sale and transfer of shares under a Tag Disposal.

6.7 Fundamental Failure

In case that the Company for two consecutive fiscal years operates at or below the adjusted EBITDA or net revenue figures as set out under Annex 6.7 for the fiscal years 2013 through 2018 (Fundamental Failure) and the Parties fail to agree upon and implement a plan to remedy such failure within ninety (90) days (or such longer period as may be mutually agreed upon by the Parties), both the Non-Managing Shareholder and the Managing Shareholders (represented by the Managing Shareholders Representative) may exercise their Final Call or their Final Put respectively, at any time during the ninety (90)-day period beginning on the earlier of (i) the day following ninety (90) days after the end of the relevant fiscal year or (ii) the day the Non-Managing

Page 14

Shareholder is, in accordance with the general reporting requirements of the managing directors, provided with the financials of the Company necessary to determine the Fundamental Failure; it being understood that the time from the Closing Date (as defined in the SPA) until the end of the fiscal year in which the Closing Date falls, shall constitute a full fiscal year. The Non-Managing Shareholder is not entitled to exercise the Final Call pursuant to this clause 6.7 if the Fundamental Failure has occurred at a time when the Managing Shareholders are no longer managing directors of the Company and the Non-Managing Shareholder has deliberately caused a Fundamental Failure.

6.8 IPO Right

6.8.1 In case of the exercise of a Final Put, the Non-Managing Shareholder may elect to not purchase all or any portion of the shares having an aggregate Fair Market Value in excess of EUR 400,000,000 (four hundred million Euros), and require the Managing Shareholders to support it in listing the shares of the Company on a US public stock exchange (or listing on a public stock exchange in a Western European jurisdiction as the Non-Managing Shareholder may designate in its free discretion, or listing in any other jurisdiction with the consent of at least one Managing Shareholder), by delivery of notice to the Managing Shareholders’ Representative, within ten (10) Business Days after the final agreement with respect to or determination of the Fair Market Value for the shares to be sold pursuant to the Final Put Notice, of the Non-Managing Shareholder’s decision to not purchase such shares, but list the shares of the Company on a public stock exchange instead (IPO Right Notice). For the avoidance of doubt, in such case the Non-Managing Shareholder shall remain obligated to purchase shares in an aggregate value of up to EUR 400,000,000 (four hundred million euros).

6.8.2 In case of the delivery of an IPO Right Notice the Managing Shareholders shall, at the direction of the Non-Managing Shareholder, be obligated to sell up to 5% of registered share capital of the Company in connection with such initial public offering, and all Parties shall use reasonable best efforts to support the Company going public at any time until the IPO Long Stop Date and in particular comply with all of the Non-Managing Shareholder’s registration rights as set out in Annex 6.8.2. If an initial public offering of the Company has not been completed within eighteen (18) months following receipt of the IPO Right Notice by the Managing Shareholders’ Representative (IPO Long Stop Date), the Managing Shareholders’ obligation to support an initial public offering of the Company shall cease and the Final Call and the Final Put shall be exercisable again for any shares of the Company still owned by the relevant shareholders. In this case the Final Call Notice and the Final Put Notice may be given during the thirty (30)-day period commencing on the date on which the lapse of such eighteen (18) month period occurs and after that annually for a thirty (30)-day period starting on the anniversary of the lapse of the

Page 15

eighteen (18) month period; for the avoidance of doubt, consideration for the shares to be transferred under the Final Call or the Final Put in this case shall be the Fair Market Value.

6.9 Closing of Put/Call Transactions

Each purchase and sale of shares of the Company under this § 6 shall be consummated at a closing within fourty-five (45) days after final agreement with respect to or determination of the Fair Market Value, determined pursuant to Annex 6.1.2; provided, however, that if the approval of any governmental body is imposed by or required under any applicable law with respect to the consummation of a purchase and sale of shares under this § 6, the closing shall be deferred to a date not later than five Business Days after the last such approval shall have been obtained or occurred. At each such closing, the Parties shall enter into a share purchase and transfer agreement substantially as attached hereto as Annex 6.9 in relation to the shares of the Company to be sold in such closing. The Parties shall give all declarations and take all actions, which are necessary or beneficial for implementing the sale and transfer of shares under this § 6.

6.10 Alternative Consideration

The Non-Managing Shareholder may, in its free discretion, decide to pay some or all of the consideration it owes under a share purchase and transfer agreement entered into pursuant to § 6.9, in the form of a number of shares of common stock in Expedia, Inc. as listed on the NASDAQ Stock Market (ticker symbol: EXPE). The value of each share of common stock in Expedia, Inc. shall, for the purpose of determining the number of common stock to be transferred as consideration, be valued at the average closing price for common stock in the Parent Guarantor as determined by the NASDAQ Stock Market for the last 30 days on which there was trading on the NASDAQ Stock Market prior to the day of the relevant closing pursuant to § 6.9. In such event, each Managing Shareholder shall use reasonable efforts to provide such attestations to the Non-Managing Shareholder as are required to determine whether or not such Managing Shareholder is an accredited investor under the United States Securities Act of 1933, as amended.

6.11 Notices

Each notice for the exercise of a put or call right under § 6 of this Agreement shall be delivered in accordance with § 16 of this Agreement and, once delivered, shall be irrevocable without the consent of the Party or Parties receiving such notice or, in the case of delivery to the Managing Shareholders, the consent of the Managing Shareholder Representative. Each notice for the exercise of a put or call right shall state the provision of this Agreement under which the notice is given, the number of the shares to be transferred and outline the further process towards closing.

Furthermore, to the extent Confidential Information exchanged during the term of this Agreement relates to customers and/or technology, the Parties shall only use it for the purpose of this Agreement and shall not pass it on to affiliated companies pursuant to §§ 15 et. seq. German Stock Corporation Act (AktG) without prior consent of the Managing Shareholders.

Confidential Information is in particular not information, which

14.2.2 a disclosure to employees and/or advisors and or affiliated companies pursuant to §§ 15 et. seq. German Stock Corporation Act (AktG) is necessary in connection with the implementation of this Agreement; or

Page 21

14.2.3 a Party is required to disclose Confidential Information under contractual agreements with financing banks; or

14.2.4 Confidential Information is disclosed to advisors bound to statutory obligation to confidentiality.

In these cases the Parties shall still use reasonably best efforts to ensure that confidentiality is kept to the greatest extent possible despite of the disclosure.

14.3 The shareholders of the Company acknowledge that the business partners of the Company are competitors of the Non-Managing Shareholder. The Company’s shareholders understand that the business partners, therefore, have a legitimate interest to keep the conditions and terms of the respective agreements with business partners strictly confidential vis-à-vis the Non-Managing Shareholder. The Non-Managing Shareholder acknowledges that the Company will not provide it with confidential information on business partners and will support the Company in communicating to its customers and business partners that such confidential information is kept confidential. This § 14.3 shall prevail over § 14.1.

§ 15

17.7 In case of a rescission or other termination of this Agreement, all rights and obligations of the Parties under this Agreement shall in general lapse and terminate; to the extent a Party rescinds or otherwise retires from this Agreement, all rights and obligations of such Party under this Agreement shall lapse and terminate to the extent not expressly provided otherwise in this Agreement. A termination of this Agreement

17.7.1 does not discharge the Parties from any liabilities or obligations, including liabilities resulting from a default or a breach of duty under this Agreement, which were already existing at the time of termination; and

Page 23

17.7.2 does not affect the provisions in § 13, § 14, § 16, and § 18, which remain valid and in effect following a termination of this Agreement.
