REGISTERED OWNER:

THIS CERTIFIES THAT the registered owner whose name is inscribed hereon is the owner of the number of non-transferable subscription rights (“Rights”) set forth above. The Rights entitle the holder thereof to subscribe for and purchase shares of common stock, par value $0.01 per share (the “Common Stock”), of Nanophase Technologies Corporation, a Delaware corporation (the “Company”), at a subscription price of $0.40 per full share, pursuant to a rights offering (the “Rights Offering”), on the terms and subject to the conditions set forth in the Prospectus. Each Right includes a basic subscription privilege and an over-subscription privilege. Under the basic subscription privilege, for each share of common stock owned as of the record date of the Rights Offering, the holder hereof is entitled to purchase 0.1 shares of Common Stock at the subscription price of $0.40 per full share.

The over-subscription privilege of each Right entitles a Rights holder, if such holder fully exercised its basic subscription privilege, to request to purchase any additional shares of Common Stock that remain unsubscribed at the expiration of the Rights Offering, subject to the availability and pro rata allocation of shares among persons exercising this over-subscription privilege, and limited to 1.6 times the number of shares purchased by that Rights holder under the basic subscription privilege, as described in the Prospectus.

The Rights represented by this Subscription Rights Certificate may be exercised by completing Form 1 and any other appropriate forms on the reverse side hereof and by returning the full payment of the subscription price for each share of Common Stock in accordance with the instructions contained herein.

Witness the seal of Nanophase Technologies Corporation and the signatures of its duly authorized officers.
