Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	Subject to certain restrictions, beginning on this date, options vest in three equal annual installments.
(2)	Each share of deferred common stock represents a right to receive one share of common stock.
(3)	1,031 shares of common stock were to be granted under the Company's 2005 Non-Employee Director Restricted Stock Plan. Such shares are vested immediately but subject to certain transfer restrictions. Pursuant to such plan, the reporting person elected to defer receipt of such shares and receive instead 1,031 shares of deferred common stock which, along with the 4,742 similar shares granted previously, will be accounted for under the Company's Non-Employee Director Deferred Compensation Plan.
(4)	The deferred common stock becomes payable upon the reporting person's termination of service as a director of the Company.
(5)	Pursuant to such plan, the reporting person elected to defer receipt of such shares and recieve 1,031 shares of deferred common stock, amounting to a cumulative total of 5,773 shares of deferred common stock received (including those received from previous grants) to date, which will all be accounted for under the Company's Non-Employee Director Deferred Compensation Plan.
Remarks: This report has been filed late due to an administrative error.  This grant is in the same amount as those issued to all Nanophase non-employee directors on April 2, 2007.  Non-employee directors receive a similar grant on the first business day of each quarter as part of their director compensation, as noted in the Company's public filings.  Each non-employee director is granted the same amount of shares as the others based upon fixed dolar values of deferred common shares calculated using the closing market price of the Company's stock on the date of each grant.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
