Within 30 days following any Change of Control Repurchase Event or, at the option of the Company, prior to any Change of Control, but after the public announcement of the Change of Control or event that may constitute the Change of Control, the Company shall deliver a notice (the “Change of Control Notice”) to each Holder of the Notes, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering (the “Change of Control Offer”) to repurchase the Notes on the repurchase date specified in the notice at the option of the Holders, which date (the “Change of Control Payment Date”) shall be no earlier than 30 days and no later than 60 days from the date such notice is delivered. The Change of Control Notice shall, if delivered prior to the date of consummation of the Change of Control, state that the Company’s obligation to repurchase the Notes is conditioned on a Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date.

(b) On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i) accept for payment all the Notes or portions of the Notes properly tendered pursuant to the Change of Control Notice;

(ii) deposit with the Paying Agent or Tender Agent appointed for such purpose an amount equal to the aggregate repurchase price in respect of all the Notes or portions of the Notes properly tendered; and

13

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of Notes being repurchased by the Company.

(c) The Paying Agent or Tender Agent shall promptly deliver to each Holder of Notes properly tendered the repurchase price for the Notes, and the Trustee shall, upon receipt of a Company Order, promptly authenticate and mail (or cause to be transferred by book-entry) to each Holder a new Note equal in principal amount to any unpurchased portion of any Notes surrendered.

(d) Notwithstanding the foregoing in this Section 4.02, the Company shall not be required to make a Change of Control Offer in connection with a Change of Control Repurchase Event if a third party makes such an offer in connection with such Change of Control Repurchase Event in the manner and at the times required and otherwise in compliance with the requirements for such a Change of Control Offer made by the Company, and such third party purchases all Notes properly tendered and not withdrawn under its offer.

(e) If Holders of not less than 95% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company pursuant to Section 4.02(d) above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described in Section 4.02(b) above, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding the redemption date (subject to the right of Holders of record on a Record Date to receive interest on the relevant interest payment date).

(f) The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any repurchase of the Notes as a result of a Change of Control Repurchase Event. To the extent the provisions of any such securities laws or regulations conflict with this Section 4.02, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.02 by virtue thereof; provided that the Company otherwise uses commercially reasonable efforts to permit Holders to exercise their rights and to fulfill its obligations in the time and in the manner specified in this Section 4.02 to the extent permitted by such securities laws or regulations.

Section 4.03. Special Mandatory Redemption. (a) Subject to Section 1.02 hereof, the provisions of Article 3 of the Base Indenture, as supplemented by the provisions of this Third Supplemental Indenture, shall apply to the Notes.

14

(b) In the event the Company does not consummate the Wrike Merger on or prior to June 30, 2021 or the Merger Agreement is terminated at any time prior thereto, the Company will be required to redeem all of the outstanding Notes on a Special Mandatory Redemption Date at a redemption price equal to 101% of the aggregate principal amount of the Notes, plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date (such redemption, a “Special Mandatory Redemption”). Notwithstanding anything to the contrary herein, the Trustee shall have no obligation to determine whether the Wrike Merger has occurred and shall conclusively rely on the delivery of an Officers’ Certificate to the effect.

(c) Notwithstanding Section 4.03(b) above, installments of interest on the Notes that are due and payable on an interest payment date falling on or prior to the Special Mandatory Redemption Date shall be payable on such interest payment date to the registered Holders as of the close of business on the relevant Record Date in accordance with the provisions of the Notes and the Indenture.

(d) Notice of any Special Mandatory Redemption will be electronically delivered or mailed, with a copy to the Trustee, within five Business Days after the occurrence of the event triggering the Special Mandatory Redemption to each Holder of Notes. If funds sufficient to pay the redemption price for such Special Mandatory Redemption of the Notes to be redeemed on the Special Mandatory Redemption Date are deposited with the Trustee or a Paying Agent on or before such Special Mandatory Redemption Date, and the other conditions related to such redemption under the Indenture are satisfied, on and after such Special Mandatory Redemption Date, the outstanding Notes will cease to bear interest.

On or before the redemption date for the Securities, the Company shall deposit with the Trustee or a Paying Agent, funds sufficient to pay the redemption price of the Securities to be redeemed on the redemption date, and (except if the redemption date shall be an interest payment date) accrued interest, if any. If less than all of the Securities are to be redeemed, the Securities to be redeemed shall be selected pro rata or by lot or by such method as the Trustee shall deem fair and appropriate, in accordance with the procedures of the Depository; provided, however, that in no event shall Securities of a minimum principal amount of $2,000 or less be redeemed in part.

Notice of any redemption shall be delivered at least 10 days but not more than 60 days before the redemption date to each Holder of the Securities to be redeemed (with a copy to the Trustee). Such notice shall state the redemption price (if known) or the formula pursuant to which the redemption price is to be determined if the redemption price cannot be determined at the time the notice is given. If the redemption price cannot be determined at the time such notice is to be given, the actual redemption price, calculated as set forth in the Indenture, shall be set forth in an Officers’ Certificate of the

A-6

Company delivered to the Trustee no later than two Business Days prior to the redemption date. Notice of redemption having been given as provided in the Indenture, the Securities called for redemption shall become due and payable on the redemption date and at the applicable redemption price, plus accrued and unpaid interest, if any, to, but excluding, the redemption date.

(6) Change of Control Repurchase Event. If a Change of Control Repurchase Event occurs with respect to the Securities, unless the Company shall have exercised its option pursuant to Section (5) hereof to redeem the Securities, each Holder of the Securities shall have the right to require the Company to repurchase all or any part (equal to minimum denominations of $2,000 and multiples of $1,000 in excess thereof) of that Holder’s Securities at a repurchase price in cash equal to 101% of the aggregate principal amount of the Securities to be repurchased plus any accrued and unpaid interest on such Securities to, but excluding, the repurchase date.

Within 30 days following any Change of Control Repurchase Event with respect to the Securities or, at the option of the Company, prior to any Change of Control, but after the public announcement of the Change of Control or event that may constitute the Change of Control, the Company shall deliver a notice (the “Change of Control Notice”) to each Holder of the Securities, with a copy to the Trustee, describing the transaction or transactions that constitute or may constitute the Change of Control Repurchase Event and offering (the “Change of Control Offer”) to repurchase such Securities on the repurchase date specified in the notice at the option of the Holders, which date (the “Change of Control Payment Date”) shall be no earlier than 30 days and no later than 60 days from the date such notice is delivered. The Change of Control Notice shall, if delivered prior to the date of consummation of the Change of Control, state that the Company’s obligation to repurchase the Securities is conditioned on a Change of Control Repurchase Event occurring on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i) accept for payment all the Securities or portions of the Securities properly tendered pursuant to the Change of Control Notice;

(ii) deposit with the Paying Agent or Tender Agent appointed for such purpose an amount equal to the aggregate repurchase price in respect of all the Securities or portions of the Securities properly tendered; and

(iii) deliver or cause to be delivered to the Trustee the Securities properly accepted, together with an Officers’ Certificate stating the aggregate principal amount of the Securities being repurchased by the Company.

If Holders of not less than 95% in aggregate principal amount of the outstanding Securities validly tender and do not withdraw such Securities in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company pursuant to Section 4.02(d) of the Third Supplemental Indenture, purchases

A-7

all of the Securities validly tendered and not withdrawn by such Holders, the Company shall have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer described above, to redeem all Securities that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding the redemption date (subject to the right of Holders of record on a Record Date to receive interest on the relevant interest payment date).

The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with any repurchase of the Securities as a result of a Change of Control Repurchase Event. To the extent the provisions of any such securities laws or regulations conflict with this Section (6), the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under this Section (6) by virtue thereof; provided that the Company otherwise uses commercially reasonable efforts to permit Holders to exercise their rights and to fulfill its obligations in the time and in the manner specified in this Section (6) to the extent permitted by such securities laws or regulations.

(7) Special Mandatory Redemption. In the event the Company does not consummate the Wrike Merger on or prior to June 30, 2021 or the Merger Agreement is terminated at any time prior thereto, the Company will be required to redeem all of the outstanding Securities on a Special Mandatory Redemption Date at a redemption price equal to 101% of the aggregate principal amount of the Securities, plus accrued and unpaid interest, if any, to, but excluding, the Special Mandatory Redemption Date (such redemption, a “Special Mandatory Redemption”). Notwithstanding anything to the contrary herein, the Trustee shall have no obligation to determine whether the Wrike Merger has occurred and shall conclusively rely on the delivery of an Officers’ Certificate to the effect.

Notwithstanding the foregoing, installments of interest on Securities that are due and payable on an interest payment date falling on or prior to the Special Mandatory Redemption Date shall be payable on such interest payment date to the registered Holders as of the close of business on the relevant Record Date in accordance with the provisions of the Securities and the Indenture.

Notice of any Special Mandatory Redemption will be electronically delivered or mailed, with a copy to the Trustee, within five Business Days after the occurrence of the event triggering the Special Mandatory Redemption to each Holder of the Securities. If funds sufficient to pay the redemption price for such Special Mandatory Redemption of the Securities to be redeemed on the Special Mandatory Redemption Date are deposited with the Trustee or a Paying Agent on or before such Special Mandatory Redemption Date, and the other conditions related to such redemption under the Indenture are satisfied, on and after such Special Mandatory Redemption Date, the outstanding Securities will cease to bear interest.

(12) Remedies. If an Event of Default with respect to the Securities occurs and is continuing, the Trustee or Holders of at least 25% in aggregate principal amount of the Securities may, by notice in writing to the Company (and the Trustee if given by the Holders), declare all the Securities to be due and payable immediately. Securityholders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require security or indemnity before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the outstanding Securities may direct the Trustee in its exercise of any trust or power with

respect to the Securities. The Trustee may withhold from Securityholders of this Series notice of any Default or Event of Default (except a Default in payment of principal or interest) if it determines in good faith that withholding notice is in their interests. The Company must furnish an annual compliance certificate to the Trustee.

(13) Trustee Dealings with Company. Subject to the provisions of the TIA, the Trustee under the Indenture, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not Trustee.
