                            STOCK PURCHASE AGREEMENT

         THIS STOCK PURCHASE AGREEMENT (the "Agreement") is dated as of
September 8, 2003 by and between NANOPHASE TECHNOLOGIES CORPORATION, a Delaware
corporation located at 1319 Marquette Drive, Romeoville, Illinois (the
"Company"), and each of the various purchasers (each, a "Purchaser", and
collectively, the "Purchasers") identified on, and a party to, an executed copy
of the Subscription Agreement to which this Agreement is an Exhibit (the
"Subscription Agreement").

                                    SECTION 1

                              Sale of Common Stock

         Subject to the terms and conditions hereof, the Company has offered,
and will issue and sell (the "Offering") to the Purchasers and the Purchasers
will buy from the Company a total of up to 453,001 shares of common stock, $.01
par value per share, of the Company (the "Common Stock") for the purchase price
of $4.415 per share, with each Purchaser purchasing the number of shares of
Common Stock for the aggregate cash purchase price indicated on the Subscription
Agreement. The shares of Common Stock to be issued and sold by the Company and
purchased by the Purchasers pursuant to this Agreement are herein referred to as
the "Shares." This Agreement and each Purchaser's obligation hereunder are not
conditioned on the sale of any minimum number of Shares.

         As an inducement for the Purchasers to purchase the Shares, subject to
the terms and conditions hereof, the Company will issue to each Purchaser a
warrant to purchase a number of shares of Common Stock equal to the number of
shares of Common Stock purchased by each Purchaser herein (a "Warrant") at an
exercise price of $4.415 for a term of twelve (12) months. Each Warrant will be
issued in substantially the form attached hereto as Appendix 1.

         The Shares, the Warrants and the shares of Common Stock issuable upon
exercise of the Warrants ("Warrant Shares", and collectively with the Shares and
the Warrants, the "Securities") will be offered and sold without registration
under the Securities Act of 1933, as amended (the "Securities Act"), in reliance
upon the exemption from registration provided by Section 4(2) of the Securities
Act and Regulation D thereunder.

         The Purchasers (and any subsequent permitted transferees) will be
entitled to the benefits of a Registration Rights Agreement, to be dated as of
the date hereof (attached to the Subscription Agreement as Exhibit B, the
"Registration Rights Agreement"), by and among the Company and the Purchasers.
Pursuant to the Registration Rights Agreement, the Company will file with the
Securities and Exchange Commission (the "SEC" or the "Commission") a shelf
registration statement on Form S-3 pursuant to SEC Rule 415 (the "Registration
Statement") under the Securities Act relating to the resale of the Shares and
the Warrant Shares by the Purchasers. The Company shall use its commercially
reasonable best efforts to cause such Registration Statement to be declared
effective within six months of the Closing and to be maintained effective until
the earlier of (i) the date on which all Securities have been resold under such
Registration Statement and (ii) the date on which all Registrable Securities (as
defined in the Registration Rights Agreement) may be resold without restriction
or limitation.

                                Closing; Delivery

         2.1.  Closing. The closing of the purchase and sale of the Shares and
Warrants hereunder (the "Closing") shall be held at the Chicago offices of
Wildman, Harrold, Allen & Dixon, counsel to the Company, or at such other place
upon which the Company and the Purchasers shall agree. The Closing shall occur
simultaneously with or immediately after the execution and delivery of this
Agreement by the Purchasers and the Company, or on such later date as the
Company and the Purchasers may agree.

         2.2.  Delivery. At the Closing, or within a reasonable period of time
thereafter, the Company will deliver to each Purchaser (i) a certificate,
registered in the name of such Purchaser for the number of Shares to be
purchased by such Purchaser against payment of the purchase price therefor by
wire transfer per the Company's wiring instructions and (ii) a Warrant. If, at
the time of Closing, the Shares are eligible for clearance and settlement
through The Depository Trust Company ("DTC"), then the Company may deliver the
Shares to the Purchasers in book-entry form through DTC.

all such maintenance requirements.

property rights (collectively, "Intellectual Property Rights") which are
necessary for use in connection with its business as now conducted and as
described in the SEC Reports. The Company has no knowledge that it has
infringed, and the Company is not infringing on, any of the Intellectual
Property Rights of any Person. Except as disclosed in the Company's SEC Reports,
there is no Proceeding which is pending, or to the Company's knowledge, is

including current or former shareholders of the Company, underwriters, brokers
or agents, has any right of first refusal, preemptive right, right of

charges, encumbrances, mortgages, hypothecations, adverse claims or equities
(each, a "Lien"), except for Liens that do not materially affect the value of
such property and do not interfere with the use made and proposed to be made of
such property by the Company. Any properties held or used under lease by the
Company are held by it under valid, subsisting and enforceable leases, with such
exceptions as are not material and do not interfere with the use made and
proposed to be made of such properties by the Company.

licenses, easements, consents, approvals, orders, permits and approvals
("Permits") necessary to own, lease and operate its properties and to conduct
their businesses as currently conducted except where the failure to possess such
Permits is not reasonably likely, individually or in the aggregate, to have a
Material Adverse Effect ("Material Permits"), and there is no Proceeding
pending, or, to the knowledge of the Company, threatened relating to the
revocation, modification, suspension or cancellation of any Material Permit. The
Company has fulfilled and performed all of the material obligations with respect
to such Permits, and no event or change in condition has occurred which allows,
or which upon notice, the lapse of time or both would allow, the revocation or
termination thereof or results in any other material impairment of the rights of
the holder of any such Permits, except for failures which would not,
individually or in the aggregate, have a Material Adverse Effect. The Company is
not in conflict with, in default under or in violation of any Material Permit.

         3.22. Insurance. The Company and its respective properties are insured
by insurers of recognized financial responsibility against such losses and risks
and in such amounts as management believes is prudent and customary in the
business in which the Company is engaged. Except as disclosed

                                                                      SPA Page 6



on Schedule 3.22, the Company has no reason to believe that it will not be able
to renew such existing insurance policies as and when such coverage expires or
to obtain similar coverage from similar insurers, at a cost that would not
materially and adversely affect the condition, financial or otherwise, or the
earnings, cash flows, business or business prospects of the Company taken as a
whole.

         3.23. Investment Company. The Company is not (i) an "investment

         3.24. No Stabilization. Neither the Company nor, to the Company's
knowledge, any of its directors, officers, or controlling persons has taken or
will take, directly or indirectly, any action designed to, or which might
reasonably be expected to cause or result in, or which has constituted, under
the Exchange Act, the stabilization or manipulation of the price of any security
of the Company to facilitate the sale or resale of the Securities.

         3.25. Labor. No strike, labor problem, dispute, slowdown, work stoppage
or disturbance with the employees of the Company exists or, to the knowledge of
the Company, is threatened.

         3.26. Stock and Other Plans. Other than as disclosed in the SEC

of the Company which is material to the Company, taken as a whole.

not currently expect to take any steps, to seek protection pursuant to any
bankruptcy, insolvency, debtor relief, reorganization or similar law, nor does
the Company have any knowledge or reason to believe that creditors of the
Company have initiated or intend to initiate involuntary bankruptcy or similar
proceedings.

         3.28. Environmental. Except as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect, (i) the

                                                                      SPA Page 7

aggregate, to have a Material Adverse Effect. With respect to such Plans, the
Company is in compliance in all respects with all applicable provisions of ERISA
and have performed all their respective obligations under such Plans, except

                                    SECTION 4

                            Covenants of the Company

         The Company hereby covenants with the Purchasers as follows:

         4.1.  Notification of Certain Events. From the date hereof until the
Closing, the Company will immediately notify each Purchaser, and confirm such
notice in writing, of (i) any filing made by the Company relating to the
Offering with Nasdaq or any securities exchange or the SEC or other securities
regulator in the United States or any other jurisdiction, and (ii) subject to
the agreement of each of the Purchasers to maintain such information in
confidence, any material changes in or affecting the financial condition,
earnings, cash flows, shareholders' equity, business or business prospects of
the Company and its subsidiaries taken as a whole.

                                                                      SPA Page 8



         4.2.  Offering Limitations. None of the Company or, to the Company's
knowledge, any of its Affiliates will solicit any offer to buy or offer to sell
shares of Common Stock or securities convertible into or exchangeable for Common
Stock by means of any form of general solicitation or general advertising (as
such terms are used in Regulation D under the Securities Act) in any manner
involving a public offering (within the meaning of Section 4(2) of the
Securities Act) prior to the effective date ("Effective Date") of the
Registration Statement.

         4.3.  RESERVED

         4.4.  Disclosures. The Company, promptly following the Closing will (i)
issue a press release announcing the sale of the Securities, and (ii) file such
press release and other appropriate information with the SEC on a Form 8-K. The
Company shall, immediately following the filing of the Registration Statement on
Form S-3 pursuant to the Registration Rights Agreement, (i) issue such press
releases and make such filings under the Exchange Act, including, without
limitation, the filing of Form 8-K, to disclose the sale of the Shares and the
filing of the Registration Statement on Form S-3 pursuant to the Registration
Rights Agreement and (ii) include in the filing of its next Form 10-Q or Form
10-K, as applicable, appropriate disclosures relating to the sale of the Shares
and the filing of such Registration Statement on Form S-3, including, without
limitation, the disclosure required by Item 701 of Regulation S-K. The Company
shall, from and after the Closing through the period that the Registration
Statement is required to be maintained, timely file all SEC Reports, comply with
all requirements under the Exchange Act, continue to list the Shares on Nasdaq

Sections 3.6, 3.13 and 3.30 hereof, which are incorporated herein.

of the Shares and the Warrants for general working capital purposes.

         4.7.  Adjustments in relation to More Favorable Terms. If, at any time
during the twelve months following the Closing, the Company issues and sells any
shares of capital stock (or debt or equity securities convertible into shares of
capital stock) (a "Financing Transaction") on pricing terms more favorable to
the purchasers in such Financing Transaction than the terms contained herein,
the Company shall take such steps as may be reasonably necessary to give the
Purchasers the benefit of such more favorable pricing terms on the Shares and
Warrants purchased hereunder. Such benefit shall be conferred by issuing
additional Shares to the Purchasers and/or increasing the number Warrant Shares
issuable upon exercise of the Warrants, as applicable; provided, however, that
the maximum number of Shares (a) purchased pursuant to this Agreement, (b)
issuable upon exercise of the Warrants, and (c) issued pursuant to this Section
4.7 will not in the aggregate exceed 19.99% of the outstanding shares of the
Company as of the date hereof. For the avoidance of doubt, the parties
acknowledge and agree that in no event will any portion of the purchase price
paid hereunder be returned or refunded to any Purchaser on account of the
application of this Section.

         The provision of Section 4.7 and Section 4.8 below shall not apply in
relation to (i) any securities issued to the Company's officers, directors and
consultants in consideration for services rendered or to be rendered whether
pursuant to the Company's equity compensation plans or otherwise, (ii)
securities issued in any merger, reorganization, recapitalization, and (iii)
securities issued as a dividend or rights offering to the Company's
stockholders.

                                                                      SPA Page 9



         4.8.  Limitation on Additional Financings. For so long as Grace
Brothers, Ltd. ("Grace") beneficially own at least 75% of the Shares purchased
hereunder, during the period commencing at the Closing and ending on the first
anniversary of the Closing, the Company will not, without the prior written
approval of Grace (which consent shall not be unreasonably withheld) issue and
sell any shares of capital stock (or debt or equity securities convertible into
shares of capital stock) in a Financing Transaction to the extent that the
aggregate consideration received by the Company through such Financing
Transaction exceeds Eight Million Dollars ($8,000,000).

                                    SECTION 5

           Representations, Warranties and Covenants of the Purchasers

         Each Purchaser, severally and not jointly, hereby represents, warrants
and covenants to the Company with respect to the purchase of the Shares by such
Purchaser and issuance of the Warrants to such Purchaser as follows:

         5.1.  Experience. Such Purchaser has substantial experience in
evaluating and investing in private placement transactions of securities in
companies similar to the Company, and the Purchaser is capable of evaluating the
merits and risks of its investment in the Company and has the capacity to
protect its own interests.

         5.2.  Qualified Institutional Buyer. Such Purchaser is a "qualified
institutional buyer," as defined in Rule 144A of the Securities Act, or an
"accredited investor," as defined in SEC Regulation D promulgated pursuant to
the Securities Act.

         5.3.  Rule 144. Such Purchaser acknowledges that the Shares, the
Warrants and the Warrant Shares must be held indefinitely unless subsequently
registered for resale under the Securities Act or unless an exemption from such
registration is available. Such Purchaser is aware of the provisions of Rule 144
promulgated under the Securities Act which permit limited resale of securities
purchased in a private placement, subject to the satisfaction of certain
conditions, including, among other things, the existence of a public market for
the shares, the availability of certain current public information about the
Company, the resale occurring not less than one year after a party has purchased
and fully paid for the security to be sold, the sale being effected through a
"broker's transaction" or in a transaction directly with a "market maker" and
the number of shares being sold during any three-month period not exceeding
specified limitations.

         5.4.  Confidential Access to Information. Such Purchaser has had an
opportunity to discuss the Company's business, management and financial affairs
with its management. It has also had an opportunity to ask questions of officers
of the Company, which questions were answered to its satisfaction. Such
Purchaser understands that such discussions, as well as any written information
issued by the Company, were intended to describe certain aspects of the
Company's business and prospects. Pursuant to a confidentiality agreement, as
contemplated by the SEC's Regulation FD, such Purchaser acknowledges that it has
been provided access to material, non-public information and that the Purchaser
will keep all such information confidential except to the extent it becomes
public through no fault of the Purchaser. Further, the Purchaser acknowledges
and understands the fact that the Company is seeking to effect the private
placement of the Shares and the Warrants is material non-public information and
disclosure of such information or use of such information by the Purchasers or
anyone receiving such information from the Purchasers in connection with the
purchase, sale or trade of the Company's securities (other than use by the
Purchasers in acquiring the Shares and the Warrants), or any hedging, derivative
or similar transactions or activities involving the Company's securities, is a
violation of

                                                                     SPA Page 10



securities laws. Neither such inquiries nor any other due diligence
investigation conducted by such Purchaser or any of its advisors or
representatives shall modify, amend or affect such Purchaser's right to rely on
the Company's representations, warranties and covenants contained herein or in
the other Agreements. The Purchaser understands that its investment in the
Shares, the Warrants and the Warrant Shares involves a high degree of risk.

         5.5.  Organization; Authorization. The Purchaser is a corporation, a
limited liability company or a partnership duly formed, validly existing and in
good standing under the laws of the jurisdiction of its organization with the
requisite power and authority, to enter into and to consummate the transactions
contemplated by the Agreements and otherwise to carry out its obligations under
the Agreements. The purchase by such Purchaser of the Shares and the Warrants
hereunder has been duly authorized by all necessary action on the part of such
Purchaser. This Agreement, when executed and delivered by such Purchaser, will
constitute a valid and binding obligation of the Purchaser, enforceable in
accordance with its terms, subject to the Bankruptcy and Equity Exception.

         5.6.  Restrictive Legend. Such Purchaser understands that the
certificates evidencing the Shares, and the Warrant Shares will bear the
following legends:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF
         1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES, OR "BLUE
         SKY," LAWS OF ANY STATE OR OTHER DOMESTIC OR FOREIGN JURISDICTION. THEY
         MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, TRANSFERRED
         OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO A REGISTRATION STATEMENT IN
         EFFECT UNDER THE SECURITIES ACT AND OTHER APPLICABLE LAWS OR A WRITTEN
         OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION
         IS NOT REQUIRED AND THAT AN EXEMPTION FROM SUCH REGISTRATION IS
         AVAILABLE FOR SUCH TRANSACTIONS UNDER THE SECURITIES ACT AND OTHER
         APPLICABLE LAWS."

         In addition, the Purchasers acknowledge that each certificate for
Shares and Warrant Shares shall bear any additional legend required by any other
applicable domestic or foreign securities or blue sky laws.

         The Company will direct its transfer agent and registrar to maintain
stop transfer instructions on record for the Securities until it has been
notified by the Company, upon the advice of counsel, that such instructions may
be waived consistent with the Securities Act and applicable domestic and foreign
securities laws. Such stop transfer instructions will limit the method of sale
of the Securities, consistent with Rule 144 or other available exemptions from
registration under the Securities Act. Any transfers other than pursuant to a
registration statement under the Securities Act will require an opinion of
counsel reasonably satisfactory to the Company and its counsel prior to such
transfers.

         5.7.  No Governmental Review. Each Purchaser understands that no United
States federal or state agency or any other government or governmental agency or
authority has passed upon or made any recommendation or endorsement of the
Shares, Warrants or Warrant Shares.

         5.8.  Residency. Such Purchaser is a resident of the jurisdiction set
forth immediately below such Purchaser's name on the Subscription Agreement.

         5.9.  Investment Intent. Such Purchaser is acquiring the Shares and the
Warrants for investment for its own account, not as a nominee or agent, and not
with the view to any distribution thereof. Such

                                                                     SPA Page 11



Purchaser understands and agrees that the Shares, the Warrants and the Warrant
Shares have not been registered under the Securities Act by reason of the
exemption from the registration provisions of the Securities Act contained in
Rule 506 of Regulation D and Section 4(2) of the Securities Act, the
availability of which depends upon, among other things, the bona fide nature of
the investment intent and the accuracy of such Purchaser's representations,
warranties and covenants as expressed herein, which are being relied upon by the
Company.

         5.10. Rights Agreement. Such Purchaser acknowledges that the Company
has entered into a Rights Agreement, dated October 28, 1998 (as amended, the
"Rights Agreement"), which Rights Agreement has been filed with the Commission
as an exhibit to the Company's periodic reports. Such Purchaser is not, and at
the time of Closing will not be, an Acquiring Person (as such term is defined in
the Rights Agreement). In conjunction with the Offering, the Company shall cause
the Rights Agreement to be amended to increase to 35% the threshold at which a
person or entity becomes an "Acquiring Person" (as defined in the Rights
Agreement).

         5.11. No Manipulation. Neither such Purchaser nor, to the Purchaser's
knowledge, any of its directors, officers, managers, subsidiaries, controlling
persons or other affiliates has taken, or presently plans to take, directly or
indirectly, any action designed to or which might reasonably be expected to
cause or result in, or which has constituted, under the Exchange Act, the
stabilization or manipulation of the price of any security of the Company to
facilitate the sale or resale of the Shares or Warrant Shares.

                                    SECTION 6

                 Conditions to Purchasers' Obligations to Close

         8.5.  Delays or Omissions. Except as expressly provided herein, no
delay or omission to exercise any right, power or remedy accruing to any
Purchaser upon any breach or default of the Company under the Agreements shall
impair any such right, power or remedy of such Purchaser, nor shall it be
construed to be a waiver of any such breach or default, or an acquiescence
therein, or of any similar breach or default thereafter occurring; nor shall any
waiver of any single breach or default be deemed a waiver of any other breach or
default theretofore or thereafter occurring. Any waiver, permit, consent or

any provisions or conditions of this Agreement, must be in writing and shall be

effect.

                                                                     SPA Page 15



         8.9.  Section Headings, etc. The titles and subtitles used in this
Agreement are used for convenience only and are not considered in construing or

         8.11. Independent Nature of Purchasers' Obligations and Rights. The
obligations of each Purchaser hereunder are several and not joint with the
obligations of the other Purchasers hereunder, and no Purchaser shall be
responsible in any way for the performance of the obligations of any other
Purchaser hereunder. The obligations of each Purchaser are not conditioned upon
the action of any other Purchaser. Nothing contained herein or in any other
agreement or document delivered at the Closing, and no action taken by any
Purchaser pursuant hereto or thereto, shall be deemed to constitute the
Purchasers as a partnership, an association, a joint venture or any other kind
of Person, or create a presumption that the Purchasers are in any way acting in
concert with respect to such obligations or the transactions contemplated by
this Agreement. Each Purchaser shall be entitled to protect and enforce its
rights, including, without limitation, the rights arising out of the Agreements,
and it shall not be necessary for any other Purchaser to be joined as an
additional party in any proceeding for such purpose.

         8.12. Further Assurances. Each party shall do and perform, or cause to
be done and performed, all such further acts and things, and shall execute and
deliver all such other agreements, certificates, instruments and documents, as
the other parties may reasonably request in order to carry out the intent and
accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

         8.13. Confidentiality. All material, non-public information disclosed
by the Company to the Purchasers pursuant to this Agreement or otherwise shall
be held strictly confidential and used by the Purchasers solely for evaluating
purchases of Securities in this Offering, provided this obligation shall not
apply to any information that is generally available to the public or becomes
available to the public without any disclosure by the Purchasers. The provisions
of this Section 8.13 shall not in any way amend or supercede the provisions of
any other confidentiality, non-disclosure or similar agreement with the Company
to which any Purchaser is bound.

         8.14. Entire Agreement; Amendment. This Agreement, the Registration
Rights Agreement, the Subscription Agreement Warrants and the other Operative
Documents constitute the entire understanding and agreement between the
Purchasers and the Company with regard to the subject matter. Except as
expressly provided herein, this Agreement, any of the other Agreements or any
term hereof may be amended, modified, waived or discharged only by a written
instrument signed by the party waiving any term, condition, or right or remedy
that benefits it hereunder.

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES SECURITIES ACT
OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE SECURITIES OR "BLUE SKY" LAWS
OF ANY STATE OR OTHER DOMESTIC OR FOREIGN JURISDICTION. NEITHER THESE SECURITIES
NOR ANY INTEREST HEREIN MAY BE SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED,
TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO A REGISTRATION STATEMENT
IN EFFECT UNDER THE SECURITIES ACT AND OTHER APPLICABLE LAWS OR UPON DELIVERY OF
A WRITTEN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION
IS NOT REQUIRED AND THAT AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE FOR
SUCH TRANSACTIONS UNDER THE SECURITIES ACT AND OTHER APPLICABLE LAWS.

THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE ISSUER THAT SUCH
SECURITY MAY BE OFFERED, RESOLD, PLEDGED, HYPOTHECATED OR OTHERWISE TRANSFERRED
OR DISPOSED OF, ONLY (1) (A) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT
UNDER THE SECURITIES ACT, (B) OUTSIDE THE UNITED STATES TO A FOREIGN PERSON IN A
TRANSACTION MEETING THE REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT, (C)
PURSUANT TO ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE
SECURITIES ACT, (AND IN THE CASE OF (B) OR (C), BASED UPON AN OPINION OF COUNSEL
IF THE COMPANY SO REQUESTS) OR (D) TO THE COMPANY, AND (2) IN EACH CASE, IN
ACCORDANCE WITH APPLICABLE BLUE SKY LAWS AND THE SECURITIES LAWS OF ANY OTHER
APPLICABLE DOMESTIC OR FOREIGN JURISDICTION. THE HOLDER WILL, AND EACH
SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY PURCHASER FROM IT THAT THE SECURITY
EVIDENCED HEREBY IS SUBJECT TO THE FOREGOING RESALE RESTRICTIONS.

THE SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE OF THIS SECURITY HAVE NOT
BEEN REGISTERED UNDER THE SECURITIES ACT OR ANY OTHER STATE SECURITIES, OR "BLUE
SKY," LAWS, AND SUCH SHARES WILL BE RESTRICTED IN THE SAME MANNER AS THESE
SECURITIES. SUCH SHARES ARE ENTITLED TO THE BENEFIT OF A REGISTRATION RIGHTS
AGREEMENT, DATED AS OF SEPTEMBER 8, 2003, BY AND AMONG THE ISSUER AND THE
PURCHASERS NAMED THEREIN, THAT COVERS THE RESALE OF THE SHARES ACQUIRED UPON
EXERCISE OF THESE WARRANTS. A COPY OF THE REGISTRATION RIGHTS AGREEMENT MAY BE
OBTAINED UPON WRITTEN REQUEST TO THE ISSUER.

                   DATE OF INITIAL ISSUANCE: SEPTEMBER 8, 2003

         THIS CERTIFIES THAT, for value received, Grace Brothers, Ltd. (the
"Holder") is entitled to purchase, subject to the exercise and other provisions
of this Warrant, from Nanophase Technologies Corporation, a Delaware corporation
(the "Company") at any time on or prior to 5:00 P.M. Eastern Time

                                                                  Warrant Page 1



on September 7, 2004 (the "Expiration Date"), up to 453,001 shares (as such
number of shares may be adjusted in accordance with Section 2 hereof, the
"Warrant Shares") of the Company's common stock, par value $.01 per share (the
"Common Stock"), at any time and from time to time, in whole or in part, at an
exercise price per share of $4.415 (subject to adjustment as provided in Section
2 hereof, the "Exercise Price"). This Warrant shall expire on September 7, 2004,
and shall become void thereafter.

         WHEREAS, the Company proposes to sell, pursuant to a Stock Purchase
Agreement, dated as of the date hereof (the "Purchase Agreement"), by and among
the Company, the Holder and the other Purchasers named therein, an aggregate of
up to 453,001shares of the Company's Common Stock and, as an inducement for the
Purchasers to purchase such shares, the Company also proposes to grant to the
Purchasers Warrants to purchase an aggregate of up to 453,001 shares of the
Company's Common Stock;

         NOW, THEREFORE, in consideration of the premises, the mutual agreements
herein contained and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereto, intending to
be legally bound, agree as follows:

Section 1.       Exercise of Warrant.

         1.1.    Vesting. The Holder's rights under this Warrant are fully
vested as of the date hereof.

         1.2.    Exercisability. This Warrant shall be exercisable, in whole or
in part, in the discretion of the holder, at any time from the date hereof until
the Expiration Date (such period, the "Exercise Period").

         1.3.    Procedure for Exercise of Warrant.

                 (a)    To exercise this Warrant in whole or in part, the Holder
         shall deliver to the Company, at Nanophase Technologies Corporation,
         1319 Marquette Drive, Romeoville, IL 60446, Facsimile No. (630)
         771-0825, Attention: Chief Financial Officer (or at such other address
         as the Company may hereafter provide), at any time prior to the
         Expiration Date: (i) a completed and signed Notice of Exercise, as
         attached hereto; (ii) cash or a certified or official bank check,
         payable to the order of the Company in the amount of the aggregate
         Exercise Price for the Warrant Shares being purchased; and (iii) this
         Warrant. Upon irrevocable payment in good collected funds of the
         aggregate Exercise Price (rounded up to the nearest cent) for the
         Warrant Shares being purchased, the Holder shall be deemed to be the
         holder of record of such Warrant Shares, notwithstanding that the stock
         transfer books of the Company may then be closed or that certificates
         representing such Warrant Shares may not then be actually delivered to
         the Holder.

         (b)     The Company shall, as promptly as practicable after completion
         of the actions specified in Section 1.3(a) above, and in no event later
         than five (5) business days after the completion of such actions,
         direct its Common Stock registrar and transfer agent to execute to the
         Holder a certificate representing the aggregate number of Warrant
         Shares specified in the Notice of Exercise. Each stock certificate so
         delivered shall be in such denomination as may be requested by the
         Holder and shall be registered in the name of the Holder. If this
         Warrant shall have been exercised only in part, the Company shall, at
         the time of delivery of said stock certificate or certificates, deliver
         to the Holder a new Warrant evidencing the right of the Holder to
         purchase the remaining Warrant Shares covered by this Warrant. The
         Company shall pay all expenses, stock transfer taxes and other charges
         payable in connection with the preparation, execution and delivery of
         stock certificates representing Common Stock issued upon exercise of
         this Warrant.

                                                                  Warrant Page 2



         1.4.    Restrictive Legend. Each certificate for Warrant Shares shall
contain the following legend:

         THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR THE
         SECURITIES OR "BLUE SKY" LAWS OF ANY STATE OR OTHER DOMESTIC OR FOREIGN
         JURISDICTION. NEITHER THESE SECURITIES NOR ANY INTEREST HEREIN MAY BE
         SOLD, OFFERED FOR SALE, PLEDGED, HYPOTHECATED, TRANSFERRED OR OTHERWISE
         DISPOSED OF EXCEPT PURSUANT TO A REGISTRATION STATEMENT IN EFFECT UNDER
         THE SECURITIES ACT AND OTHER APPLICABLE LAWS OR UPON DELIVERY OF A
         WRITTEN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
         REGISTRATION IS NOT REQUIRED AND THAT AN EXEMPTION FROM SUCH
         REGISTRATION IS AVAILABLE FOR SUCH TRANSACTIONS UNDER THE SECURITIES
         ACT AND OTHER APPLICABLE LAWS.

         THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE ISSUER THAT
         SUCH SECURITY MAY BE OFFERED, RESOLD, PLEDGED, HYPOTHECATED OR
         OTHERWISE TRANSFERRED OR DISPOSED OF, ONLY (1) (A) PURSUANT TO AN
         EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, (B) OUTSIDE
         THE UNITED STATES TO A FOREIGN PERSON IN A TRANSACTION MEETING THE
         REQUIREMENTS OF RULE 904 UNDER THE SECURITIES ACT, (C) PURSUANT TO
         ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES
         ACT, (AND IN THE CASE OF (B) OR (C), BASED UPON AN OPINION OF COUNSEL
         IF THE COMPANY SO REQUESTS) OR (D) TO THE COMPANY, AND (2) IN EACH
         CASE, IN ACCORDANCE WITH APPLICABLE BLUE SKY LAWS AND THE SECURITIES
         LAWS OF ANY OTHER APPLICABLE DOMESTIC OR FOREIGN JURISDICTION. THE
         HOLDER WILL, AND EACH SUBSEQUENT HOLDER IS REQUIRED TO, NOTIFY ANY
         PURCHASER FROM IT THAT THE SECURITY EVIDENCED HEREBY IS SUBJECT TO THE
         FOREGOING RESALE RESTRICTIONS.

         THE SHARES OF COMMON STOCK ISSUABLE UPON THE EXERCISE OF THIS SECURITY
         HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OR ANY OTHER STATE
         SECURITIES, OR "BLUE SKY," LAWS, AND SUCH SHARES WILL BE RESTRICTED IN
         THE SAME MANNER AS THESE SECURITIES. SUCH SHARES ARE ENTITLED TO THE
         BENEFIT OF A REGISTRATION RIGHTS AGREEMENT, DATED AS OF SEPTEMBER 8,
         2003, BY AND AMONG THE ISSUER AND THE PURCHASERS NAMED THEREIN, THAT
         COVERS THE RESALE OF THE SHARES ACQUIRED UPON EXERCISE OF THESE
         WARRANTS. A COPY OF THE REGISTRATION RIGHTS AGREEMENT MAY BE OBTAINED
         UPON WRITTEN REQUEST TO THE ISSUER.

         The certificates shall also bear any additional legends that are
required by, or are appropriate with respect to the rules and regulation of, the
United States Securities and Exchange Commission (the "SEC") and any applicable
state, foreign or other securities or "blue sky" authorities. The Company's
transfer agent and registrar will maintain stop transfer instructions on record
for the Warrant Shares until it has been notified by the Company, upon the
advice of counsel, that such instructions may be waived. Such stop transfer
instructions will limit the method of sale of the Warrant Shares, consistent
with Rule 144 or other available exemptions from registration under the
Securities Act of 1933, as amended. Any transfers

                                                                  Warrant Page 3



will require an opinion of counsel reasonably satisfactory to the Company and
its counsel prior to such transfers.

         1.5.    Character of Warrant Shares. The Company represents, warrants
and covenants that all Warrant Shares shall be duly authorized, validly issued,
and, upon payment of the Exercise Price therefor, fully paid and nonassessable,
and free from all taxes, liens, hypothecations, security interests, adverse
claims or interests and charges created in respect of the issue thereof.

         1.6     No Fractional Shares. The Company shall have no obligation to
issue fractional shares, or scrip representing fractional shares, of its Common
Stock under this Warrant, and, to the extent that the Holder would otherwise be
entitled to purchase and/or receive fractional shares of Common Stock hereunder,
such fractional shares shall instead be disregarded and shall be of no value or
consequence.

Section 2.       Certain Adjustments.

         2.1.    Stock Dividends, Subdivisions and Combinations. If at any time
the Company shall:

                 (a)    establish a record date for the determination of holders
         of record of its Common Stock for the purpose of entitling them to
         receive a dividend payable in, or other distribution of, additional
         shares of the Company's Common Stock,

                 (b)    subdivide its outstanding shares of Common Stock into a
         larger number of shares of Common Stock, or

                 (c)    combine its outstanding shares of Common Stock into a
         smaller number of shares of Common Stock,

then (1) the number of Warrant Shares for which this Warrant is exercisable
immediately after the occurrence of any such event shall be adjusted to equal
the number of shares of Common Stock which a record holder of the same number of
shares of Common Stock for which this Warrant is exercisable immediately prior
to the occurrence of such event would own or be entitled to receive upon or as a
result of such event, and (2) the Exercise Price shall be adjusted to equal (x)
the Exercise Price multiplied by the Warrant Shares for which this Warrant is
exercisable immediately prior to the adjustment divided by (y) the Warrant
Shares for which this Warrant is exercisable immediately after such adjustment.

         2.2.    Adjustment Procedures. The following provisions shall be
applicable to adjustments to be made pursuant to Section 2.1 hereof:

                 (a)    When Adjustments to be Made. The adjustments required by
         this Section 2 shall be made whenever and as often as any event
         requiring an adjustment shall occur.

                 (b)    Fractional Interests. In computing adjustments under
         this Section 2, fractional interests in the Common Stock shall be taken
         into account to the nearest 1/10th of a share. In no event, however,
         shall fractional shares or scrip representing fractional shares be
         issued upon the exercise of this Warrant.

                 (c)    When Adjustment Not Required. If the Company establishes
         a record date for the determination of the holders of record of the
         Common Stock for the purpose of entitling such holders to receive a
         dividend or distribution payable in Common Stock and thereafter and
         before the distribution to shareholders thereof, legally abandons its
         plan to pay or deliver such dividend

                                                                  Warrant Page 4



         or distribution, then no adjustment shall be required by reason of the
         establishment of such record date and any such adjustment previously
         made in respect thereof shall be rescinded and annulled.

         2.3.    Reorganization, Reclassification, Merger, Consolidation or
Share Exchange. If the Company at any time reorganizes or reclassifies the
outstanding shares of Common Stock (other than a change in par value, or from no
par value to par value, or from par value to no par value, or as a result of a
subdivision or combination) or consolidates with, merges into, or effects a
share exchange with, another person or entity (where the Company is not the
continuing corporation after such transaction) or the Company sells all or
substantially all its assets in one or a series of transactions (each, a
"Business Combination"), then the Holder shall thereafter be entitled to receive
upon the exercise of this Warrant in whole or in part, the same kind and number
of shares of stock and other securities, cash or other property (and upon the
same terms and with the same rights) as would have been distributed to the
Holder upon such reorganization, reclassification or Business Combination had
the Holder exercised this Warrant immediately prior to such reorganization,
reclassification or Business Combination (subject to subsequent adjustments
under this Section 2), and the Exercise Price shall be adjusted appropriately to
reflect such action and adjustment.

    If any such reorganization, reclassification, consolidation, merger or share
    exchange results in a cash distribution in excess of the Exercise Price
    provided by this Warrant, the Holder may, at the Holder's option, exercise
    this Warrant without making payment of the Exercise Price, and in such case
    the Company or its successors and assigns shall, upon distribution to such
    Holder, consider the Exercise Price to have been paid in full, and in making
    settlement to such Holder, shall deduct an amount equal to the Exercise
    Price from the cash amount otherwise payable to such Holder. Notwithstanding
    anything herein to the contrary, the Company will not effect any such
    reorganization, reclassification or Business Combination, unless, prior to
    the consummation thereof, the person or entity that may be required to
    deliver any stock, securities or other assets upon the exercise of this
    Warrant shall agree expressly in writing to bound hereby, to perform timely
    and observe each and every provision of this Warrant and the Registration
    Rights Agreement, and to deliver such stock, cash, securities or other
    assets to the Holder.

         2.4.    Officer's Certificate. Upon each adjustment of the Exercise
Price and the Warrant Shares issuable upon the exercise of this Warrant, and in
the event of any change in the rights of the Holder by reason of other events
herein set forth, then and in each such case, the Company will promptly prepare
a certificate of a responsible officer of the Company, stating the adjusted
Exercise Price, the adjusted number of Warrant Shares so issuable, and setting
forth in reasonable detail the method of calculation and the facts upon which
such calculation is based. The Company will promptly mail a copy of such
certificate to the Holder. Such calculation shall be final and binding on the
parties and shall be conclusive evidence of the correctness of the computation
with respect to any such adjustment of the Exercise Price and any such change in
the number of Warrant Shares so issuable, absent manifest error.

         2.5.    Notice of Certain Proposed Actions. In the event the Company
shall propose to take any action of the types described in Sections 2.1 or 2.3
above, then the Company shall forward, at the same time and in the same manner,
to the Holder such notice and related proxy or other materials, if any, that the
Company gives to the holders of the Common Stock. Failure to give such notice,
or any defect therein, however, shall not affect the legality or validity of any
such action.

Section 3.       Ownership and Transfer.

         3.1.    Ownership. The Company may deem and treat the person in whose
name this Warrant is registered as the sole Holder and owner hereof
(notwithstanding any notations of ownership or writing

                                                                  Warrant Page 5



hereon made by anyone other than the Company) for all purposes, and the Company
shall not be affected by any notice to the contrary until presentation of this
Warrant to the Company for registration of transfer.

         3.2.    Transfers. Upon the sale, disposition, transfer or conveyance
of this Warrant, the purchaser, transferee or other recipient hereof shall,
together with the previous Holder hereof, promptly notify the Company of such
sale, disposition, transfer or conveyance and shall provide such recipient's
name, address and capacity in which this Warrant is held, and present such other
information as the Company may reasonably request, and such recipient will
thereafter be subject to, and bound by, the terms and provisions of, this
Warrant to the same extent as the previous Holder. Nothing in this Section 3.2
is intended to or shall affect the limitations on sales, offers for sale,
dispositions and transfers hereunder.

         3.3.    Replacement. Upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft or destruction of this Warrant, and of
indemnity or security reasonably satisfactory to it, or upon surrender of this
Warrant if mutilated, the Company will make and deliver a new Warrant of like
tenor, in lieu of this Warrant. This Warrant shall be promptly canceled by the
Company upon the surrender hereof in connection with any transfer or
replacement. Except as otherwise provided above in the case of the loss, theft
or destruction of a Warrant, the Company shall pay all expenses, taxes and other
charges payable in connection with any transfer or replacement of this Warrant.
Applicants for such substitute Warrants shall also comply with such other
reasonable regulations and pay such other reasonable charges incidental thereto
as the Company may reasonably prescribe. Any such new Warrant shall constitute
an original contractual obligation of the Company, whether or not the allegedly
lost, stolen, mutilated or destroyed Warrant shall at any time be presented.

         3.4     Cancellation of Warrant. Any Warrant surrendered upon exercise
or for split up, combination, exchange or transfer, or purchased or otherwise
acquired by the Company, shall be cancelled and shall not be reissued by the
Company; and, except as provided herein in the case of the purchase of less than
all of the Warrant Shares pursuant to the third sentence of Section 1.3(b)
hereof or in the case of a Warrant surrendered upon a split up, combination,
exchange or transfer, no Warrant shall be issued hereunder in lieu of such
cancelled Warrant. Any Warrant so cancelled shall be marked cancelled and
destroyed by the Company.

         3.5     Expiration of Warrant. This Warrant shall expire on September
7, 2004, and shall become void thereafter.

Section 4.       Miscellaneous.

         4.1.    Reservation of Shares. The Company covenants that, at all times
during the Exercise Period, it will reserve from its authorized and unissued
Common Stock a sufficient number of shares of Common Stock to provide for the
issuance of Common Stock upon the exercise of this Warrant, as well as for the
issuance of Common Stock pursuant to any other outstanding warrants, options or
other instruments convertible or exercisable into the Company's Common Stock,
and with respect to any employee benefit or similar plans.

         4.2.    No Rights as Shareholder; Limitation of Liability. This Warrant
shall not entitle the Holder to any of the rights of a holder of Company Common
Stock, including, without limitation, the right to vote, to receive dividends
and other distributions, or to receive any notice of, or to attend, meetings of
Company shareholders, prior to exercise of this Warrant and irrevocable payment
in good, collected funds of the Exercise Price therefor.

                                                                  Warrant Page 6



         4.3.    Amendment. This Warrant may only be modified or amended and any
provision hereof may only be waived by a writing executed by the Company and the
Holder of this Warrant.

         4.4.    Successors and Assigns. This Warrant shall be binding upon, and
inure to the benefit of, the parties hereto and their respective successors and
assigns permitted hereunder, and no other parties are intended to, or shall have
any rights hereunder, whether as third party beneficiaries or otherwise.

         4.5.    Governing Law. This Warrant shall be governed by, and construed
and enforced in accordance with, the laws of the State of Delaware.

         4.6.    Entire Agreement. The Holder is entitled, with respect to his
ownership of this Warrant and/or the Warrant Shares to the benefits of the
Purchase Agreement and the Registration Rights Agreement, dated as of the date
hereof (the "Registration Rights Agreement"), by and among the Company, the
Holder and the other Purchasers named in the Purchase Agreement. Except as
otherwise expressly provided herein, this Warrant (including the Purchase
Agreement, the Registration Rights Agreement and any other agreements,
instruments and other documents referred to herein or therein) constitute the
entire agreement among the parties hereto with respect to the transactions
contemplated hereunder and supersedes all prior arrangements or understandings
with respect thereto, written or oral.

         4.7.    Headings, etc. The descriptive headings of the articles and
sections of this Warrant are inserted for convenience of reference only and
shall not control or affect the meaning or construction of any of the provisions
hereof. As used herein, the singular shall include the plural and vice versa and
the terms "include," "included" and "including" shall mean without limitation by
way of enumeration or otherwise.

         4.8.    Counterparts. This Warrant may be executed in any number of

                                     THE HOLDER

                                     _____________________________________
                                     Name

                                                                  Warrant Page 9



                                    EXHIBIT B

                          REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT (the "Agreement") is made and
entered into as of September 8, 2003, by and among NANOPHASE TECHNOLOGIES
CORPORATION, a Delaware corporation (the "Company"), and those persons (the
"Purchasers") identified on, and a party to, an executed copy of the
Subscription Agreement to which this Agreement is an Exhibit (the "Subscription
Agreement").

         This Agreement is made pursuant to the Subscription Agreement and the
Stock Purchase Agreement, dated on or about the date hereof, which is an Exhibit
to the Subscription Agreement (the "Stock Purchase Agreement"), by and between
the Company and the Purchasers, pursuant to which the Company is issuing and
selling (i) up to 453,001shares of its common stock, $.01 par value per share
(the "Common Stock" or the "Shares") to the Purchasers and (ii) to each
Purchaser a warrant to purchase a number of shares of Common Stock equal to 100%
of the whole number of shares of Common Stock purchased by each Purchaser
therein (a "Warrant").

         The Shares, the Warrants and the shares of Common Stock issuable upon
exercise of the Warrants ("Warrant Shares") are referred to herein as the
"Securities".

         The Shares are being offered and sold to the Purchasers without
registration under the Securities Act of 1933, as amended (the "Securities
Act"), in reliance upon the exemption from registration provided by Section 4(2)
of the Securities Act, and the provisions of Rule 506 of Regulation D,
promulgated under the Securities Act. In order to induce the Purchasers to enter
into the Stock Purchase Agreement, the Company has agreed to provide to the
Purchasers (and their direct and indirect permitted transferees, if any) the
registration rights set forth in this Agreement with respect to the resale of
the Securities. The execution and delivery of this Agreement is a condition to
the Closing under the Stock Purchase Agreement. Capitalized terms used but not
defined herein shall have the meaning provided in the Stock Purchase Agreement.

         In consideration of the foregoing premises and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties, intending to be legally bound, agree as follows:

                                    SECTION 1

                               Registration Rights

         1.1.  Filing of Form S-3 Resale Registration Statement. As soon as
practical and, within thirty (30) business days after the closing under the
Stock Purchase Agreement, the Company shall file with the Securities and
Exchange Commission (the "SEC" or the "Commission") a registration statement on
Form S-3 pursuant to Rule 415 under the Securities Act, or, in the event that
Form S-3 is unavailable to the Company, a registration statement on such other
SEC Form that is available to the Company (together with any exhibits,
amendments or supplements thereto, and any documents incorporated by reference
therein, the "Registration Statement"), with respect to the resale of the Shares
and Warrant Shares, and any securities of the Company issued as a dividend or
other distribution with respect to, or in exchange for or in replacement of, the
Shares or Warrant Shares. The securities described in the preceding sentence are
collectively referred to herein as the "Registrable Securities"; provided, that
the term "Registrable

                                            Registration Rights Agreement Page 1



Securities" shall not include securities transferred to a person other than a
permitted transferee. The Registration Statement may not include securities of
the Company other than Registrable Securities.

         1.2.  Effectiveness of Registration Statement. The Company shall,
subject to Section 6 hereof, use its commercially reasonable efforts to cause
the Registration Statement to become effective as soon as practicable and within
six (6) months after the date hereof, and shall use its commercially reasonable
best efforts to keep the Registration Statement continuously effective from the
date such Registration Statement becomes effective until the earlier of (i) the
date on which all Securities have been resold under such Registration Statement
and (ii) the date on which all Registrable Securities may be resold without
restriction or limitation.

         1.3.  Supplements; Amendments. Subject to Section 6 hereof, the Company
shall supplement or amend the Registration Statement, (i) as required by Form
S-3, including, without limitation, the instructions applicable to Form S-3, or
by the Securities Act, the Securities Exchange Act of 1934, as amended (the
"Exchange Act"), or the rules and regulations promulgated under the Securities
Act or the Exchange Act, respectively, and (ii) to include in the Registration
Statement any additional securities that become Registrable Securities by
operation of the definition thereof. The Company shall furnish to the holders of
the Registrable Securities, or their permitted transferees, as appropriate
(collectively, the "Holders"), to which the Registration Statement relates
copies of any such supplement or amendment sufficiently in advance (but in no
event less than five (5) business days in advance) of its use and/or filing with
the Commission to allow the Holders a meaningful opportunity to comment thereon
with respect to the information contained therein regarding the Holders and any
plan for resale of the Registrable Securities. The Holders acknowledge that they
have supplied the information regarding themselves and their plan of resale in
the Registration Statement to be filed within five (5) business days of the
Closing and hereby waive any notice of the initial filing of the Registration
Statement, and that such Holders and their successors and assigns will promptly
notify the Company of any changes in such information.

                                    SECTION 2

                                    Expenses

         The Company shall pay all expenses, fees and costs incurred in
connection with the preparation, filing, distribution and effectiveness of the
Registration Statement and any supplements or amendments thereto, whether or not
the Registration Statement becomes effective, and whether all, none or some of
the Registrable Securities are sold pursuant to the Registration Statement,
including, without limitation, all registration and filing fees, printing
expenses, fees and disbursements of counsel for the Company, fees and state
securities, or "blue sky," fees and expenses, and the expense of any special
audits incident to or required by, or in connection with the filing and
effectiveness of the Registration Statement (but excluding the compensation of
regular employees of the Company, which shall be paid in any event by the
Company). The Holders shall pay all underwriting fees and discounts, selling
commissions, brokerage fees and stock transfer taxes applicable to the
Registrable Securities sold by such Holder and the fees and expenses of their
counsel, if any.

                                    SECTION 3

                             Registration Procedures

         3.1.  Registration. The Company will advise the Holders as to the
status of the preparation, filing and effectiveness of the Registration
Statement and, at the Company's expense, will do the following:

                                            Registration Rights Agreement Page 2



               (a) furnish to each Holder a copy of the Registration Statement
         (including all exhibits thereto) and any prospectus forming a part
         thereof and any amendments and supplements thereto (including all
         documents incorporated or deemed incorporated by reference therein
         prior to the effectiveness of the Registration Statement and including
         each preliminary prospectus) and any other prospectus filed under Rule
         424 under the Securities Act, which documents, other than documents
         incorporated or deemed incorporated by reference, will be subject to
         the review of the Holders and any such underwriter for a period of at
         least three (3) business days, and the Company shall not file the
         Registration Statement or such prospectus or any amendment or
         supplement to the Registration Statement or prospectus if any Holder
         shall reasonably object within three (3) business days after the
         receipt thereof. A Holder shall be deemed to have reasonably objected
         to such filing only if the Registration Statement, amendment,
         prospectus or supplement, as applicable, as proposed to be filed,
         contains a material misstatement or omission with respect to such
         Holder or its plan of resale;

               (b) furnish to each Holder one conformed copy of the Registration
         Statement and of each amendment and supplement thereto (in each case
         including all exhibits) and such number of copies of the prospectus
         forming a part of the Registration Statement (including each
         preliminary prospectus) and any other prospectus filed under Rule 424
         under the Securities Act, in conformity with the requirements of the
         Securities Act, and such other documents, including, without
         limitation, documents incorporated or deemed to be incorporated by
         reference prior to the effectiveness of such Registration Statement, as
         each of the Holders or any such underwriter, from time to time may
         reasonably request;

               (c) to the extent practicable, promptly upon the filing of any
         document that is to be incorporated by reference into the Registration
         Statement or prospectus forming a part thereof subsequent to the
         effectiveness thereof, and in any event no later than five (5) business
         days after such document is filed with the Commission, provide copies
         of such document to the Holders, if requested, and make representatives
         of the Company available for discussion of such document and other
         customary due diligence matters; and provide promptly to the Holders
         upon request any document filed by the Company with the Commission
         pursuant to the requirements of Section 13 and Section 15 of the
         Exchange Act;

               (d) make available at reasonable times for inspection by the
         Holders, and any attorney, accountant, financial adviser or other
         representative (collectively, "Representatives") retained by the
         Holders, subject to the recipient's prior written agreement to keep
         such information confidential and not use or disclose it, all financial
         and other records, pertinent corporate documents and properties of the
         Company and cause the officers, directors and employees of the Company
         to supply all information reasonably requested by the Holders or their
         respective Representatives in connection with the preparation, filing
         and effectiveness of the Registration Statement;

               (e) use its commercially reasonable best efforts (i) to register
         or qualify all Registrable Securities covered by the Registration
         Statement under state securities, or "blue sky," laws of such States of
         the United States of America where required and where an exemption is
         not available and as the Holders of Registrable Securities covered by
         the Registration Statement shall reasonably request, (ii) to keep such
         registration or qualification in effect for so long as the Registration
         Statement is required to be effective hereunder, and (iii) to take any
         other action which may be reasonably necessary or advisable to enable
         the Holders to consummate the disposition of the securities to be sold
         by the Holders in such jurisdictions, consistent with the plan of
         distribution described in the prospectus included in the Registration
         Statement, except that the Company shall not for any such purpose be
         required to qualify generally to do business as a

                                            Registration Rights Agreement Page 3



         foreign corporation in any jurisdiction where it is not so qualified,
         or to execute a general consent to service of process in effecting such
         registration, qualification or compliance, unless the Company is
         already subject to service in such jurisdiction and except as may be
         required by the Securities Act or applicable rules or regulations
         thereunder;

               (f) use its commercially reasonable best efforts to cause all
         Registrable Securities covered by the Registration Statement to be
         registered or qualified with or approved by all other applicable
         Governmental Authorities as may be necessary, in the opinion of counsel
         to the Company and counsel to the Holders of Registrable Securities, to
         enable the Holders thereof the consummate the disposition of such
         Registrable Securities;

               (g) subject to Section 6 hereof, promptly notify each Holder of
         Registrable Securities covered by the Registration Statement (i) upon
         discovery that, or upon the occurrence of any event as a result of
         which, the prospectus forming a part of the Registration Statement, as
         then in effect, includes an untrue statement of a material fact or
         omits to state any material fact required to be stated therein or
         necessary to make the statements therein, in the light of the
         circumstances under which they were made, not misleading, (ii) of the
         issuance by the Commission of any stop order suspending the
         effectiveness of the Registration Statement or the initiation of
         proceedings for that purpose, (iii) of any request by the Commission
         for (A) amendments to the Registration Statement or any document
         incorporated or deemed to be incorporated by reference in the
         Registration Statement, or (B) supplements to the prospectus forming a
         part of the Registration Statement, or (C) additional information, or
         (iv) of the receipt by the Company of any notification with respect to
         the suspension of the registration, qualification or exemption from
         registration or qualification of any of the Registrable Securities for
         sale in any jurisdiction or the initiation of any proceeding for such
         purpose, and at the request of any such Holder promptly prepare and
         file an amendment to the Registration Statement or a supplement to the
         prospectus as the Company may deem necessary so that, as thereafter
         delivered to the purchasers of such securities, such prospectus shall
         not include an untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; and furnish to each Holder a reasonable
         number of copies of such supplement to, or amendment of, such
         registration statement and prospectus, and, in the event of a stop
         order, use its commercially reasonable best efforts to obtain the
         withdrawal of any order suspending the effectiveness of any the
         Registration Statement, or the lifting of any suspension of the
         qualification (or exemption from qualification) of any of the
         Registrable Securities for sale in any jurisdiction;

               (h) if reasonably requested by any Holder or if required by law
         or SEC or other applicable rule or regulation, promptly incorporate in
         the Registration Statement such appropriate information as the Holder
         may reasonably request to have included therein by filing a Form 8-K,
         or filing a supplement to the prospectus, to reflect any change in the
         information regarding the Holder, and make all required filings with
         the Commission in respect of any offer or sale of Registrable
         Securities or any amendment or supplement to the Registration Statement
         or related prospectus;

               (i) otherwise use its commercially reasonable best efforts to
         comply with all applicable rules and regulations, and make available to
         its security holders, as soon as reasonably practicable, an earnings
         statement covering the period of at least 12 months, but not more than
         18 months, beginning with the first full calendar month after the
         effective date of the Registration Statement, which earnings statement
         shall satisfy the provisions of Section 11(a) of the Securities Act and
         Rule 158 promulgated thereunder and to provide promptly to the Holders
         upon request

                                            Registration Rights Agreement Page 4



         any document filed by the Company with the Commission pursuant to the
         requirements of Section 13 and Section 15 of the Exchange Act; and

               (j) use its commercially reasonable best efforts to cause all
         Registrable Securities included in the Registration Statement to be
         listed on Nasdaq and each securities exchange on which securities of
         the same class are then listed, or, if not then listed on any
         securities exchange or Nasdaq, to be eligible for trading in any
         over-the-counter market or trading system in which securities of the
         same class are then traded.

                                    SECTION 4

                                 Indemnification

         4.1.  Indemnification by the Company. The Company will indemnify:

               (a)  each of the Holders, as applicable,

               (b)  each of the Holder's officers, directors, members and
                    partners, and

               (c)  each individual, partnership, joint stock company,
                    corporation, trust, unincorporated organization, government
                    agency or political subdivision (each of the foregoing, a
                    "Person") controlling each of the Holders within the meaning
                    of SEC Rule 405 under the Securities Act,

with respect to the Registration Statement, against all expenses, claims,
losses, damages and liabilities (or actions, investigations or proceedings in
respect thereof) (collectively, a "Claim") arising out of or based on any actual
or alleged untrue statement of a material fact, or any omission of a material
fact required to be stated therein or necessary in order to make the statements
included therein not misleading, contained in the Registration Statement, any
prospectus or other offering document (including any related registration
statement, notification or the like) incident to the registration, qualification
or compliance, or any violation by the Company of the Securities Act or the
Exchange Act or any other laws or any rule or regulation thereunder applicable
to the Company and relating to action or inaction required of the Company in
connection with any such registration, qualification or compliance, and will
reimburse each of the Holders, each of its officers, directors, members and
partners, and each Person controlling each of the Holders, for any legal and any
other expenses reasonably incurred in connection with investigating and
defending any such Claim; provided, however, that the Company will not be liable
in any such case to the extent that any such Claim (i) arises out of or is based
on any untrue statement or omission based upon written information furnished to
the Company by the Holders or their Representatives and stated to be
specifically for use therein, or (ii) is finally judicially determined to have
resulted primarily from the gross negligence or willful misconduct of any person
or entity set forth in subsections (a) through (c) above.

         4.2.  Indemnification by the Holders. Each of the Holders will, if
Registrable Securities held by it are included in the securities as to which
such Registration Statement is being effected, indemnify the Company, each of
its directors and officers, and each Person who "controls" the Company within
the meaning of SEC Rule 405 under the Securities Act, against all Claims arising
out of or based on any actual or alleged untrue statement of a material fact, or
any omission or a material fact required to be stated therein or necessary in
order to make the statement included or incorporated therein not misleading,
contained in the Registration Statement, prospectus, or other offering document
made by or on behalf of such Holder, and will reimburse the Company, its
directors, officers, partners, members or control

                                            Registration Rights Agreement Page 5



Persons for any legal or any other expenses reasonably incurred in connection
with investigating and defending any such Claim, in each case to the extent, but
only to the extent, that such untrue statement (or alleged untrue statement) or
omission (or alleged omission) is made in the Registration Statement, prospectus
or other document in reliance upon and in conformity with written information
furnished to the Company by or on behalf of such Holder and stated to be
specifically for use therein; provided, however, that the obligations of each of
the Holders hereunder shall be limited to an amount equal to the net proceeds
received by such Holder from the sale of the Registrable Securities pursuant to
the Registration Statement.

         4.3.  Procedures. Each party entitled to indemnification under this
Agreement (each, an "Indemnified Party") shall give notice to the party required
to provide indemnification (the "Indemnifying Party") promptly after such
Indemnified Party has actual knowledge of any Claim as to which indemnity may be
sought, and shall permit the Indemnifying Party to assume the defense of any
such Claim; provided that counsel for the Indemnifying Party, who shall conduct
the defense of such Claim, shall be approved by the Indemnified Party (whose
approval shall not unreasonably be withheld), and the Indemnified Party may
participate in such defense at such party's expense (unless the Indemnified
Party shall have reasonably concluded that there may be a conflict of interest
between the Indemnifying Party and the Indemnified Party in such action, in
which case the fees and expenses of one such counsel for all Indemnified Parties
shall be at the expense of the Indemnifying Party), and provided further that
the failure of any Indemnified Party to give notice as provided herein shall not
relieve the Indemnifying Party of its obligations under this Agreement unless
the Indemnifying Party is materially prejudiced thereby. No Indemnifying Party,
in the investigation or defense of any such Claim shall, except with the consent
of each Indemnified Party (which consent shall not be unreasonably withheld or
delayed), consent to entry of any judgment or enter into any settlement or
compromise which does not include an unconditional release of the Indemnified
Party from all liability in respect to such Claim. Each Indemnified Party shall
furnish such information regarding itself or the Claim in question as an
Indemnifying Party may reasonably request in writing and as shall be reasonably
required in connection with the investigation and defense of such Claim.

         4.4.  Contribution. If the indemnification provided for in this
Agreement is held by a court of competent jurisdiction to be unavailable to an
Indemnified Party with respect to any Claim, then the Indemnifying Party, in
lieu of indemnifying such Indemnified Party hereunder, shall contribute to the
amount paid or payable by such Indemnified Party as a result of such loss,
liability, claim, damage or expense in such proportion as is appropriate to
reflect the relative fault of the Indemnifying Party on the one hand and of the
Indemnified Party on the other in connection with the statements or omissions
which resulted in such Claim, as well as any other relevant equitable
considerations; provided, however, that the Company will not be liable in any
such case to the extent that any such Claim (i) arises out of or is based on any
untrue statement or omission based upon written information furnished to the
Company by the Holders or their Representatives and stated to be specifically
for use therein, or (ii) is finally judicially determined to have resulted
primarily from the gross negligence or willful misconduct of any person or
entity set forth in Section 4.1(a) through 4.1(c) above. The relative fault of
the Indemnifying Party and of the Indemnified Party shall be determined by
reference to, among other things, whether the untrue (or alleged untrue)
statement of a material fact or the omission (or alleged omission) to state a
material fact relates to information supplied by the Indemnifying Party or by
the Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission,
and provided that each Holder shall not be required to contribute, in the
aggregate, more than the net proceeds received by the Holders from the sale of
the Registrable Securities pursuant to the Registration Statement.

                                    SECTION 5

                     Provision of Information by the Holders

         Each of the Holders whose Registrable Securities are included in the
Registration Statement shall furnish to the Company such information regarding
such Holder as the Company may reasonably request in writing and as shall be
reasonably required or advisable in connection with any registration,
qualification or compliance referred to in this Agreement, and shall promptly
notify the Company if such information becomes incorrect or misleading, or
requires amendment or updating. Each of the Holders agrees that the plan of
distribution included in any prospectus relating to the Registrable Securities
shall be as set forth on Schedule 3 hereto and that such Holder will not resell
any Registrable Securities pursuant to the Registration Statement in any manner
other than as provided therein or herein. The other information regarding the
Holders required for the initial filing of the Registration Statement has been
provided by each Holder on the Subscription Agreement. Each Holder represents,
warrants and covenants to the Company that the information regarding such Holder
that appears in the Subscription Agreement is accurate and complete in all
material respects consistent with Commission Regulation S-K, Items 507 and 508.
Upon written request from the Company, the Purchaser will confirm promptly the
sale of any Shares or Warrant Shares pursuant to Rule 144 or the Registration
Statement.

                                    SECTION 6

                             Holdback; Postponement

         Notwithstanding the other provisions of this Agreement, if (a) there is
material non-public information regarding the Company which the Company's Board
of Directors reasonably and in good faith determines not to be in the Company's
best interest to disclose and which the Company is not otherwise required to
disclose, or (b) there is a extraordinary business opportunity (including but
not limited to the acquisition or disposition of assets (other than in the
ordinary course of business) or any merger, consolidation, tender offer or other
similar extraordinary transaction not in the ordinary course of business)
available to the Company which the Company's Board of Directors reasonably and
in good faith determines not to be in the Company's best interest to disclose,
then the Company may (upon not less than two trading days prior written notice
by same day delivery of fax or hand delivery) postpone or suspend filing or
effectiveness of a registration statement for a period not to exceed 45 days,
provided that the Company may not postpone or suspend filing or effectiveness of
a registration statement for more than 90 days in the aggregate during any
365-day period and there shall be an aggregate of not more than two (2)
suspensions during any 365-day period; provided, however that no postponement or
suspension shall be permitted for consecutive 45 day periods arising out of the
same set of facts, circumstances or transactions.

                                    SECTION 7

                            Rule 144 Reporting, Etc.

         7.1.  SEC Reporting Compliance. With a view to making available the
benefits of certain rules and regulations of the Commission which may at any
time permit the sale of the Registrable Securities to the public without
registration, through the second anniversary of this Agreement, the Company
will:

                 (a)   make and keep "current public information" regarding the
         Company available, as defined in Commission Rule 144(c) under the
         Securities Act;

                 (b)   use its commercially reasonable best efforts to file with
         the Commission in a timely manner all SEC Reports and other filings and
         documents required of the Company under the Securities Act and the
         Exchange Act and otherwise; and

                                            Registration Rights Agreement Page 7



                 (c)   so long as a Holder owns any Registrable Securities,
         furnish the Holder forthwith upon request a written statement by the
         Company as to its compliance with the reporting requirements under the
         Securities Act and the Exchange Act, including compliance with SEC Rule
         144(c), a copy of the most recent annual or quarterly report of the
         Company, and such other reports and documents of the Company and other
         information in the possession of, or reasonably obtainable by, the
         Company as a Holder may reasonably request in availing itself of any
         rule or regulation of the Commission allowing a Holder to sell any such
         securities without registration.

         7.2.  Stock Purchase Agreement Covenants. The Company will comply with
its covenants under Section 4 of the Stock Purchase Agreement, which are
incorporated herein by this reference.

assigned, in whole or in part, to any transferee of Registrable Securities
permitted in accordance with the Stock Purchase Agreement, which transferee,
upon registration on the Company's or its transfer agent's books and records as
a holder of record of Registrable Securities, shall be considered thereafter to
be a Holder (provided that any transferee who is not an affiliate of a Purchaser
shall be a Holder only with respect to such Registrable Securities so acquired
and any stock of the Company issued as a dividend or other distribution with
respect to, or in exchange for or in replacement of, such Registrable
Securities) and shall be bound by all obligations and limitations of this
Agreement and the Stock Purchase Agreement.

         8.2.  Section Headings. The titles and headings of the sections and
subsections of this Agreement are inserted for convenience only and shall not be
deemed to constitute a part thereof.

in accordance with the laws of the State of Delaware.

         8.5.  Successors and Assigns; No Third Party Beneficiaries. This
Agreement shall inure to the benefit of and be binding upon the successors and
permitted assigns of each of the parties. No other person is intended to or
shall have any rights or remedies hereunder, whether as a third part beneficiary
or otherwise.

         8.6.  Counterparts. Persons may become parties to this Agreement be
entering into the Subscription Agreement, which may be executed in one or more
identical counterparts, each of which shall be deemed an original and all of
which shall be one and the same agreement. Any signature that is delivered by

         8.7.  Remedies. Each Holder of Registrable Securities, in addition to
being entitled to exercise all rights granted by law, including recovery of
damages, will be entitled to specific performance of its rights under this
Agreement. The Company agrees that monetary damages would not be adequate

of this Agreement and hereby agrees to waive the defense in any action for
specific performance that a remedy at law would be adequate.

         8.8.  Severability. In the event that any provision contained herein is
unenforceable, the remaining provisions shall continue in full force and effect.

         8.9.  Delays or Omissions. It is agreed that no delay or omission to
exercise any right, power or remedy accruing to the Holders, upon any breach or
default of the Company under this Agreement, shall impair any such right, power
or remedy, nor shall it be construed to be a waiver of any provision hereof, or
of any similar breach or default thereafter occurring; nor shall any wavier of
any single breach or default be deemed a waiver of any other breach or default
theretofore or thereafter occurring. It is further agreed that any waiver,
permit, consent or approval of any kind or character by a Holder of any breach
or default under this Agreement, or any waiver by a Holder of any provisions or
conditions of this Agreement, must be in writing and shall be effective only to
the extent specifically set forth in the writing, and that all remedies, either
under this Agreement, or by law or otherwise afforded to a Holder, shall be
cumulative and not alternative.

         8.10. Attorney's Fees. If any action at law or in equity is necessary
to enforce or interpret the terms of this Agreement, the prevailing party shall
be entitled to reasonable attorney's fees, costs and necessary disbursements in
addition to any other relief to which such party may be entitled.

         8.11. Entire Agreement; Amendment. This Agreement, the Subscription
Agreement and the Operative Documents constitute the entire understanding and
agreement of the parties with respect to the subject matter hereof and supersede
all prior understandings, written or otherwise, among such parties. This
Agreement may be amended only in a writing signed by the Company and the Holders
of a majority of the then outstanding Registrable Securities.

                                                                    SCHEDULE B-1

                              Plan of Distribution

         Any or all of the shares offered by the selling shareholders may be
offered for sale and sold by, or on behalf of, the selling shareholders from
time to time in varying amounts, including in block transactions, on the Nasdaq
Stock Market, or the over-the-counter market, in privately negotiated
transactions, though put or call options transactions relating to the shares,
through short sales, or a combination of such methods of sale, at prices
prevailing in such market or as may be negotiated at the time of the sale. The
shares may be sold by the selling shareholders directly to one or more
purchasers, through agents designated from time to time or to or through
broker-dealers designated from time to time. In the event the shares are
publicly offered through broker-dealers or agents, the selling shareholders may
enter into agreements with respect thereto. Such broker-dealers or agents may
receive compensation in the form of discounts, concessions or commissions from
the selling shareholders, and any such broker-dealers or agents that participate
in the distribution of the shares may be deemed to be underwriters within the
meaning of the Securities Act, and any profit on the sale of the shares by them
and any discounts and commissions might be deemed to be underwriting discounts
or commissions under the Securities Act. Any such broker-dealers and agents may
engage in transactions with, and perform services for, the Company. At the time
a particular offer of shares is made by the selling shareholders, to the extent
required, a prospectus supplement will be distributed which will set forth the
aggregate number of shares being offered, and the terms of the offering,
including the public offering price thereof, the name or names of any
broker-dealers or agents, any discounts, commissions and other items
constituting compensation from, and the resulting net proceeds to, the selling
shareholders.

         As used herein, "selling shareholders" includes donees and pledgees
selling shares received from a named selling shareholder after the date of this
prospectus.

         Selling shareholders also may resell all or a portion of the shares in
open market transactions in reliance on Rule 144 under the Securities Act,
provided they meet the criteria and conform to the requirements of such rule.

         In order to comply with the securities laws of certain states, sales of
shares offered hereby to the public in such states may be made only through
broker-dealers who are registered or licensed in such states. Sales of shares
offered hereby must also be made by the selling shareholders in compliance with
other applicable state securities laws and regulations.
