The following constitutes Amendment No. 1 to the Schedule 13D filed by the undersigned ("Amendment No. 1").  This Amendment No. 1 amends the Schedule 13D as specifically set forth herein.

Item 4. Purpose of Transaction.

Item 4 is hereby amended to add the following:

On November 12, 2016, the Reporting Persons entered into a Support Agreement with the Issuer and Siemens Industry, Inc. ("Siemens"). Pursuant to the terms of the Support Agreement, the Reporting Persons agreed, among other things, to vote the shares of Common Stock beneficially owned by them in favor of the merger of Meadowlark Subsidiary Corporation, a wholly owned subsidiary of Siemens, with and into the Issuer (the "Merger"), at any meeting of shareholders called for such purpose. Solely in the event of the failure by the Reporting Persons to vote their shares of Common Stock in such a manner, the Reporting Persons have granted to the Issuer and Siemens an irrevocable proxy (the "Irrevocable Proxy) to vote the Reporting Persons' shares of Common Stock in favor of the Merger at any meeting of shareholders called for such purpose. The Irrevocable Proxy automatically terminates upon termination of the Support Agreement. In addition, until the earliest of:  (1) such time as the Issuer's shareholders have approved the Merger, (2) the termination of the merger agreement, or (3) the Issuer's board of directors having changed its recommendation as to the Merger, the Reporting Persons have agreed not to transfer their shares of Common Stock, except for transfers pursuant to which they retain the right to vote the Common Stock.

The foregoing description of the Support Agreement is qualified in its entirety by reference to the Support Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

ITEM 5. Interest in Securities of the Issuer.

Item 5(a) is hereby amended and restated to read as follows:

(a)As of the date hereof, Elliott, Elliott International and EICA collectively have combined economic exposure in the Issuer of approximately 8.3% of the shares of Common Stock outstanding.

The aggregate percentage of Common Stock reported owned by each person named herein is based upon 108,155,975 shares of Common Stock outstanding as of August 26, 2016, which is the total number of shares of Common Stock outstanding as reported in the Issuer's Quarterly Report on Form 10-Q filed with the Securities and Exchange Commission on August 30, 2016.

As of the date hereof, Elliott beneficially owned 1,544,000 shares of Common Stock, constituting approximately 1.4% of the shares of Common Stock outstanding.

As of the date hereof, Elliott International beneficially owned 3,281,000 shares of Common Stock, constituting approximately 3.0% of the shares of Common Stock outstanding. EICA, as the investment manager of Elliott International, may be deemed to beneficially own the 3,281,000 shares of Common Stock beneficially owned by Elliott International, constituting approximately 3.0% of the shares of Common Stock outstanding.

Collectively, Elliott, Elliott International and EICA beneficially own 4,825,000 shares of Common Stock, constituting approximately 4.5% of the shares of Common Stock outstanding.

Collectively, Elliott, Elliott International and EICA have economic exposure comparable to approximately 3.8% of the shares of Common Stock outstanding pursuant to the Derivative Agreements, as disclosed in Item 6.

Item 6. Contracts, Arrangements, Understandings or Relationships With Respect to Securities of the Issuer.

Item 6 is hereby amended and restated to read as follows:

On November 12, 2016, the Reporting Persons entered into the Support Agreement defined and described in Item 4 and granted to the Issuer and Siemens the Irrevocable Proxy.

Elliott, itself and through The Liverpool Limited Partnership, a Bermuda limited partnership and a wholly-owned subsidiary of Elliott ("Liverpool"), and Elliott International have entered into notional principal amount derivative agreements (the "Derivative Agreements") in the form of cash settled swaps with respect to 1,316,774 and 2,798,143 shares of Common Stock of the Issuer, respectively (representing economic exposure comparable to approximately 1.2% and 2.6% of the shares of Common Stock of the Issuer, respectively). Collectively, the Derivative Agreements held by the Reporting Persons represent economic exposure comparable to an interest in approximately 3.8% of the shares of Common Stock. The Derivative Agreements provide Elliott and Elliott International with economic results that are comparable to the economic results of ownership but do not provide them with the power to vote or direct the voting or dispose of or direct the disposition of the shares that are referenced in the Derivative Agreements (such shares, the "Subject Shares"). The Reporting Persons disclaim beneficial ownership in the Subject Shares. The counterparties to the Derivative Agreements are unaffiliated third party financial institutions.

On September 29, 2016, Elliott, Elliott International and EICA entered into a Joint Filing Agreement (the "Joint Filing Agreement") in which the parties agreed to the joint filing on behalf of each of them of statements on Schedule 13D with respect to the securities of the Issuer to the extent required by applicable law. The Joint Filing Agreement is attached as an exhibit to the Schedule 13D and is incorporated herein by reference.

Except as described above in this Item 6, none of the Reporting Persons has any contracts, arrangements, understandings or relationships with respect to the securities of the Issuer.

Item 7. Material to be Filed as Exhibits.

Item 7 is hereby amended to add the following exhibit:

Exhibit 99.1 – Support Agreement dated as of November 12, 2016, among Mentor Graphics Corporation, Siemens Industry, Inc. and the shareholders of Mentor Graphics Corporation listed on the signature pages thereto.
