This Amendment No. 1 to Schedule 13D (this “Statement”) is being filed on behalf of the undersigned to amend the Schedule 13D (the “Schedule 13D”), which was originally filed with the Securities and Exchange Commission on February 24, 2021.  Unless otherwise indicated, all capitalized terms used herein but not defined herein shall have the same meanings as set forth in the Schedule 13D.

This Statement amends and supplements the Schedule 13D.  All of the information set forth in the Schedule 13D is incorporated herein by reference in response to Items 1 through 7 of this Amendment, except as otherwise set forth below.  This Amendment should be read together with the Schedule 13D.

Items 3 and 4 are hereby amended and supplemented to include the following:

Items 3 and 4.

As announced and further described by Apex in the Form 8-K filed by Apex with the SEC on April 5, 2021, on April 1, 2021, the Merger was completed. As a result of the Merger, Merger Sub merged with and into Apex, with Apex surviving as the continuing entity as a wholly-owned direct subsidiary of Parent (the “Surviving Corporation”).

At the effective time of the Merger (the “Effective Time”), (i) each share of Common Stock (other than (x) Common Stock that is owned by Parent or the Company or any of their respective direct or indirect wholly-owned subsidiaries and (y) Common Stock that is owned by stockholders who have perfected and not withdrawn a demand for appraisal rights) was automatically canceled and ceased to exist, and were converted into the right to receive, upon the terms and subject to the conditions set forth in the Merger Agreement, $2.00 in cash, without interest, less any required withholding taxes (the “Merger Consideration”), (ii) each Company option that was outstanding immediately prior to the Effective Time, whether or not then vested or exercisable, was, by virtue of the Merger and without any action on the part of the holder thereof, cancelled without payment therefor and has no further force or effect, and (iii) each restricted stock unit covering shares of Common Stock (each, a “Company RSU”) that was outstanding immediately prior to the Effective Time, whether or not then vested, vested in full and was canceled and converted into the right to receive an amount in cash, without interest, equal to the product of (A) the aggregate number of shares of Common Stock subject to such Company RSU, multiplied by (B) $2.00, less any required withholding taxes.

The aggregate purchase price paid by Parent in connection with the Merger was approximately $69.1 million. Parent funded the consideration and certain related fees and expenses through approximately $39.6 million of debt and approximately $29.5 million of equity commitments.

Item 5.

Item 5 is hereby amended and restated in its entirety:

(a)-(b)  As a result of the Merger, Merger Sub was merged with and into Apex, with Apex surviving as the continuing entity as a wholly-owned direct subsidiary of Parent. As such, 100 shares of Common Stock, par value $0.01 per share, of the Surviving Corporation (the “Surviving Corporation Common Stock”) are outstanding and the Reporting Persons may be deemed to be the beneficial owner of, and have shared dispositive and voting power with respect to, 100 shares of Surviving Corporation Common Stock as of the Effective Time.

(c)	Except as described in this Statement (including the schedules to the 13D), during the last sixty (60) days there were no transactions in the Surviving Corporation Common Stock effected by the Reporting Persons.

(d)	No person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Surviving Corporation Common Stock that may be deemed to be beneficially owned by the Reporting Persons.

(e)	Not applicable.
