Subsequent Events	23. Subsequent Events Merger Agreement On January 18, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Microsoft and Anchorage Merger Sub Inc. (“Merger Sub”), a wholly owned subsidiary of Microsoft, in which we agreed to be acquired for $95.00 in cash per issued and outstanding share of our common stock, par value $0.000001 per share (the “Shares”) in an all-cash transaction. Pursuant to the terms of the Merger Agreement, our acquisition will be accomplished through the merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as a wholly owned subsidiary of Microsoft. Pursuant to the terms of the Merger Agreement, and subject to the terms and conditions set forth therein, at the effective time of the Merger (the “Effective Time”), each Share (other than Shares (1) held by the Company as treasury stock (excluding certain Shares held by a wholly owned subsidiary of the Company, which shares will remain outstanding and unaffected by the Merger), (2) owned by Microsoft or Merger Sub, (3) owned by any direct or indirect wholly owned subsidiary of Microsoft or Merger Sub or (4) held by stockholders who have neither voted in favor of adoption of the Merger Agreement nor consented thereto in writing and who have properly and validly exercised their statutory rights of appraisal in respect of such Shares in accordance with Section 262 of the Delaware General Corporation Law, in each case immediately prior to the Effective Time) issued and outstanding immediately prior to the Effective Time will be cancelled and automatically converted into the right to receive $95.00 in cash, without interest. We have agreed to various customary covenants and agreements, including, among others, agreements to conduct our business in the ordinary course during the period between the execution of the Merger Agreement and the Effective Time. We do not believe these restrictions will prevent us from meeting our debt service obligations, ongoing costs of operations, working capital needs or capital expenditure requirements. If the Merger Agreement is terminated under certain specified circumstances, we or Microsoft will be required to pay a termination. We will be required to pay Microsoft a termination fee of approximately $2.27 billion under specified circumstances, including termination of the Merger Agreement in connection with our entry into an agreement with respect to a Superior Proposal (as defined in the Merger Agreement) prior to us receiving stockholder approval of the Merger, or termination by Microsoft upon a Company Board Recommendation Change (as defined in the Merger Agreement), in each case, if certain other conditions are met. Microsoft will be required to pay us a reverse termination fee under specified circumstances, including termination of the Merger Agreement due to a permanent injunction arising from Antitrust Laws (as defined in the Merger Agreement) when we are not then in material breach of any provision of the Merger Agreement and if certain other conditions are met, in an amount equal to (1) $2.0 billion if the termination notice is provided prior to January 18, 2023, (2) $2.5 billion if the termination notice is provided after January 18, 2023, and prior to April 18, 2023, or (3) $3.0 billion if the termination notice is provided at any time after April 18, 2023. The consummation of the Merger is subject to customary closing conditions, including, among others, (1) the approval and adoption of the Merger Agreement by our stockholders, (2) the absence of any court order or law prohibiting (or seeking to prohibit) the consummation of the Merger, (3) the termination or expiration of any applicable waiting period or periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (as amended) and specified approvals under certain other antitrust and foreign investment laws, subject to certain limitations, (4) compliance by us and Microsoft in all material respects with our respective obligations under the Merger Agreement, and (5) subject to specified exceptions and qualifications for materiality, the accuracy of representations and warranties made by us and Microsoft, respectively, as of the signing date and the closing date.
