SCHEDULE 13D

Page 6 of 9 Pages

Preliminary Note. Pursuant to Rule 13d-2 promulgated under the Act, this amendment to Schedule 13D (this "Amendment No. 2") amends the Schedule 13D filed on June 30, 2016 (the "Original Schedule 13D"), as amended on January 31, 2018, ("Amendment No. 1"). The Original Schedule 13D, Amendment No. 1, and this Amendment No. 2 are collectively referred to herein as the "Schedule 13D". Capitalized terms used but not defined in this Amendment No. 2 shall have the meanings given to them in the Original Schedule 13D (as amended by Amendment No. 1). The Original Schedule 13D (as amended by Amendment No. 1) remains in full force and effect, except as specifically amended by this Amendment No. 2.

On March 20, 2018, the Company, Merger Sub and Parent completed the transactions contemplated by the Agreement and Plan of Merger, dated as of January 25, 2018, by and among the Company, Merger Sub and Parent (as may be amended from time to time, the "Merger Agreement"). Pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Company (the "Merger"), with the Company surviving the Merger as a wholly-owned subsidiary of Parent and Merger Sub ceasing to exist following the Merger.

Item 3.

Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended and restated in its entirety to read as follows:

As of the close of business on the date hereof, the Reporting Persons no longer may be deemed to beneficially own any Shares.

Item 4.

Purpose of Transaction.

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following paragraphs at the start of Item 4:

On March 20, 2018, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into the Company, with the Company surviving the Merger as a wholly-owned subsidiary of Parent and Merger Sub ceasing to exist following the Merger. In connection with the Merger, (i) the Reporting Persons each sold all of the Shares owned by them for the purchase price of $26.75 per share in cash, without interest, and subject to any required withholding taxes, as contemplated by the Tender and Support Agreement and (ii) Mr. Robert Averick resigned from the Company's board of directors, as reported by the Company in a Current Report on Form 8-K filed on March 20, 2018 (File No.: 001-33919).

SCHEDULE 13D

Item 5. Interest in Securities of the Issuer.

Item 5 of the Schedule 13D is hereby amended and restated in its entirety to read as follows:

(a) and (b)	1. The Trust¹
	Sole Voting Power	-0-	0%
	Shared Voting Power	-0-	0%
	Sole Dispositive Power	-0-	0%
	Shared Dispositive Power	-0-	0%
	Aggregate Voting and Dispositive Power	-0-	0%

	2. M3C²
	Sole Voting Power	-0-	0%
	Shared Voting Power	-0-	0%
	Sole Dispositive Power	-0-	0%
	Shared Dispositive Power	-0-	0%
	Aggregate Voting and Dispositive Power	-0-	0%

	3. Mr. Averick³
	Sole Voting Power	-0-	0%
	Shared Voting Power	-0-	0%
	Sole Dispositive Power	-0-	0%
	Shared Dispositive Power	-0-	0%
	Aggregate Voting and Dispositive Power	-0-	0%

	4. Piton⁴
	Sole Voting Power	-0-	0%
	Shared Voting Power	-0-	0%
	Sole Dispositive Power	-0-	0%
	Shared Dispositive Power	-0-	0%
	Aggregate Voting and Dispositive Power	-0-	0%

¹	The Trust is a member of Piton, along with other "Family Clients" (as defined in Investment Advisers Act Rule 202(a)(11)(G)-1 (the "Family Office Rule")) of Kokino.

²	M3C is a member of Piton, along with other Family Clients of Kokino.

Mr. Averick's principal occupation is acting as a Portfolio Manager at Kokino, which is a single-family office that provides investment management services only to its Family Clients, including the Trust, M3C and Piton. Mr. Averick holds an economic interest in Piton (which interest may be held directly and, from time to time, indirectly through PCM). Also, Mr. Averick's incentive compensation as an employee of Kokino, which is calculated in Kokino's discretion, may be based, among other things, on the performance of Shares held by the Trust, M3C and Piton. Such compensation may be paid in cash and/or by way of increasing Mr. Averick's minority interest in Piton (either directly or indirectly through PCM).

⁴

Piton is a pooled investment vehicle formed for the benefit of a single family and certain "key employees" (as defined in the Family Office Rule) of Kokino. The Trust, M3C and Mr. Averick are members of Piton, along with other Family Clients of Kokino. Piton is managed by its managing member, PCM. PCM is in turn managed by its managing member, Kokino. Additionally, Kokino is the trading manager of Piton and provides investment management services to the Trust and M3C, and in those capacities Kokino acts on behalf of such Reporting Persons as an agent. Robert Averick, in his capacity as an employee of Kokino, manages the Trust's, M3C's and Piton's respective investments in Shares. PCM and Kokino are each a "family office" (as defined in the Family Office Rule) of the same family, and any voting power or investment power PCM or Kokino may hold over the Shares is ultimately attributed to the Reporting Persons reporting on this Schedule 13D.
