RECITALS OF THE COMPANY

WHEREAS, pursuant to the Indenture, the Company issued $143,750,000 aggregate principal amount of 2.50% Convertible Senior Notes due 2024 (the “Notes”);

WHEREAS, on November 10, 2019, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Open Text Corporation (“OpenText”) and Coral Merger Sub Inc., a wholly-owned subsidiary of OpenText (“Merger Sub”);

WHEREAS, pursuant to the Merger Agreement, upon the terms and subject to the conditions thereof, Merger Sub commenced a tender offer (the “Offer”) to acquire all of the outstanding shares of Common Stock (the “Shares”), at an offer price of $23.00 per Share in cash, without interest and net of any applicable withholding taxes;

WHEREAS, subject to the satisfaction or waiver of certain conditions, Merger Sub will (i) promptly after the expiration date of the Offer accept for payment all Shares tendered (and not validly withdrawn) pursuant to the Offer (the time of such acceptance, the “Offer Acceptance Time”) and (ii) promptly after the Offer Acceptance Time pay for such Shares;

WHEREAS, upon the terms and subject to the conditions set forth in the Merger Agreement and in accordance with Section 251(h) of the Delaware General Corporation Law, Merger Sub will merge with and into the Company, with the Company surviving as a wholly-owned subsidiary of OpenText (the “Merger”), without a meeting or vote of stockholders of the Company. At the effective time of the Merger (the “Effective Time”), the Shares not purchased pursuant to the Offer (other than Shares held by the Company, OpenText, Merger Sub, any wholly-owned subsidiary of the Company, OpenText or Merger Sub or by stockholders of the Company who have perfected their statutory rights of appraisal under Delaware law) will each be converted into the right to receive $23.00 per Share in cash, in each case without interest and net of any withholding;

WHEREAS, pursuant to Section 14.07(a) of the Indenture, the Merger constitutes a Specified Corporate Event, and the Company is required to execute with the Trustee a supplemental indenture providing that, at and after the Effective Time, the right to convert each $1,000 principal amount of Notes will be changed into a right to convert such principal amount of Notes into the number of Units of Reference Property that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to the Merger would have been entitled to receive upon such Specified Corporate Event;

WHEREAS, pursuant to the terms of the Merger Agreement and Section 14.07(a) of the Indenture, at and after the Effective Time, a Unit of Reference Property will be comprised of $23.00 in cash;

WHEREAS, Section 10.01(g) of the Indenture provides that the Company and the Trustee may amend or supplement the Indenture and the Notes, without the consent of Holders of any of the Notes at the time outstanding, in connection with any Specified Corporate Event, provided that the Notes are convertible into Reference Property, subject to Section 14.02 of the Indenture, and to make certain related changes to the terms of the Indenture and the Notes to the extent expressly required by the Indenture;

WHEREAS, the Company has requested that the Trustee execute and deliver this Supplemental Indenture;

WHEREAS, in connection with the execution and delivery of this Supplemental Indenture, the Trustee has received an Officer’s Certificate as contemplated by Sections 7.02(b), 7.07, 10.05, 14.07 and 17.06 of the Indenture and an Opinion of Counsel as contemplated by Sections 10.05 and 17.06 of the Indenture; and

WHEREAS, all conditions precedent provided for in the Indenture relating to the execution of this Supplemental Indenture have been complied with.

NOW, THEREFORE, THIS SUPPLEMENTAL INDENTURE WITNESSETH:
