NANOPHASE TECHNOLOGIES CORPORATION

NOTES TO FINANCIAL STATEMENTS

(Unaudited)

(1) Basis
of Presentation

The accompanying unaudited interim financial statements of Nanophase Technologies Corporation
(Nanophase or the Company, including we or us) reflect all adjustments (consisting of normal recurring adjustments) which, in the opinion of management, are necessary for a fair presentation of the
financial position and operating results of the Company for the interim periods presented. Operating results for the three months ended March 31, 2010 are not necessarily indicative of the results that may be expected for the year ending
December 31, 2010.

These financial statements should be read in conjunction with the Companys audited financial
statements and notes thereto for the year ended December 31, 2009, included in the Companys Annual Report on Form 10-K for the year ended December 31, 2009, as filed with the Securities and Exchange Commission.

(2) Description of Business

Nanophase is a nanomaterials developer and commercial manufacturer with an integrated family of nanomaterial technologies. Nanophase
produces engineered nanomaterial products for use in a variety of diverse existing and developing markets: sunscreens, personal care, architectural coatings, industrial coating ingredients, abrasion-resistant applications, plastic additives and a
variety of polishing applications, including semiconductors and optics. New markets and applications are also being developed. We target markets where we believe practical, high added value solutions are likely to be found using our nanoengineered
products. We work with leaders in these targeted markets to identify and supply their material and performance requirements. Finally, we have applied our technology and developed a complete window cleaning and polishing product family for the
Architectural Windows Market under the trade name NanoUltra. The Company was incorporated in Illinois on November 25, 1989, and became a Delaware corporation on November 30, 1997. The Companys common stock trades on the NASDAQ
Global Market under the symbol NANX.

While product sales comprise the majority of our revenue, we also recognize revenue in
connection with a technology license and other sources from time to time. These activities are not expected to drive the long-term growth of the business. For this reason we classify such revenue as other revenue in our Statement of
Operations, as it does not represent revenue directly from our nanocrystalline materials.

(3) Financial Instruments

The fair value framework requires the categorization of assets and liabilities into three levels based upon the assumptions (inputs) used
to price the assets or liabilities. Level 1 provides the most reliable measure of fair value, whereas Level 3 generally requires significant management judgment. The three levels are defined as follows:



| |  |  | Level 1: Unadjusted quoted prices in active markets for identical assets and liabilities.
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | Level 2: Observable inputs other than those included in Level 1. For example, quoted prices for
| | - |  | -----------------------------------------------------------------------------------------------

| | similar assets or liabilities in active markets or quoted prices for identical assets or liabilities in inactive markets.
| | -------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3: Unobservable inputs reflecting managements own assumptions about the inputs used in pricing the asset or liability.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------

As of March 31, 2010, the fair values of our financial assets are approximately categorized as
follows:

On March 26, 2010, the Company entered into an
agreement to sell its remaining auction rate securities (ARS) for $4 million to Credit Suisse. This sale was completed and funds were received on April 1, 2010.

We accounted for this agreement as a subsequent event and classified these securities as current assets on our December 31, 2009
balance sheet. We also recorded a gain in our December 31, 2009 statement of operations equal to the $440,000 other than temporary impairment taken during 2008 related to these securities, and recorded a current receivable for this amount.

(6) Share-Based Compensation

The Company follows FASB ASC Topic 718 (formerly SFAS 123(R)), Share-Based Payments, in which compensation expense is recognized only for
share-based payments expected to vest. The Company recognized compensation expense related to stock options of $86,509 and $93,796 for the three month period ended March 31, 2010 and 2009, respectively. The Company also recognized stock
compensation expense related to accelerated vesting of stock options pursuant to severance agreements in the amount of $0 and $210,694 for the three month period ended March 31, 2010 and 2009, respectively.

As of March 31, 2010, there was approximately $465,000 of total unrecognized compensation cost related to nonvested share-based
compensation arrangements granted under the Companys stock option plans. That cost is expected to be recognized over a remaining weighted-average period of 1.5 years.

Employees Stock Options and Stock Grants

During the three months ended March 31, 2010 and 2009, no shares of common stock were issued pursuant to option exercises. For the
three months ended March 31, 2010, stock options exercisable into 10,000 shares of common stock were granted compared to none for the same period in 2009. For the

##### Table of Contents

three months ended March 31, 2010, stock options exercisable into 11,000 shares of common stock were forfeited compared to 154,600 shares for the same period in 2009.

Stock Appreciation Rights

On
January 4, 2010, the Company granted its outside directors stock appreciation rights (SARs) totaling 15,250 shares, under the Companys Amended and Restated 2006 Stock Appreciation Rights Plan. The fair value of the awards granted
was $21,895 and is included in stock-based compensation expense for the three months ended March 31, 2010. The SARs granted vested immediately and are payable upon the directors removal or resignation from the position of director.

The fair value of SARs awards granted in 2009 increased by $47,181 during the quarter ended March 31, 2010, and is
included in stock-based compensation expense for the three months ended March 31, 2010.

For the three months ended
March 31, 2010 and 2009, the Company was to grant its outside directors shares of restricted common stock totaling 0 and 15,250 shares, respectively, under the Companys 2005 Non-Employee Director Restricted Stock Plan. However, each
outside director elected to defer receipt of the restricted stock until the termination of their services to the Company. The deferral of restricted stock is being accounted for under the Companys Non-Employee Director Deferred Compensation
Plan. The fair value of the awards granted was $0 and $11,590, respectively, for the restricted share rights and is included in stock-based compensation expense for the three months ended March 31, 2010 and 2009, respectively.

As of March 31, 2010, the Company does not have any unvested restricted stock or performance shares outstanding.

For the three months ended March 31, 2010 10,000 options were granted. The following table illustrates the various assumptions used
to calculate the Black-Scholes option pricing model for the periods presented:

(7) Significant
Customers and Contingencies

Sales to three customers constituted approximately 68%, 10% and 7%, respectively, of the
Companys total revenue for the three months ended March 31, 2010. Amounts included in accounts receivable on March 31, 2010 relating to these three customers were approximately $645,000, $196,000 and $0, respectively. Revenue from
these three customers constituted approximately 54%, 0% and 12% respectively, of the Companys total revenue for the three months ended March 31, 2009. Amounts included in accounts receivable on March 31, 2009 relating to these three
customers were approximately $269,000, $0 and $0 respectively.

##### Table of Contents

The Company currently has a supply agreement with BASF Corporation (BASF), the
Companys largest customer, and a technology development agreement with Altana Chemie, that have contingencies outlined in them which could potentially result in the license of technology and/or the sale of production equipment, providing
capacity sufficient to meet the customers production needs, from the Company to the customer, if triggered by the Companys failure to meet certain performance requirements, certain other obligations and/or certain financial condition
covenants. The financial condition covenants in one of the Companys supply agreements with its largest customer, as amended, trigger a technology transfer (license or, optionally, an equipment sale) in the event (a) that
earnings of the Company for a twelve month period ending with its most recently published quarterly financial statements are less than zero and its cash and cash equivalents are less than $2,000,000, (b) of an acceleration of any debt maturity
having a principal amount of more than $10,000,000, or (c) of the Companys insolvency, as further defined within the agreement. In the event of an equipment sale, upon incurring a triggering event, the equipment would be sold to the
customer at 115% of the equipments net book value. Under another of the Companys supply agreements with BASF, upon the Companys breach of its contractual obligations to BASF, the Company would be required to sell BASF certain
production equipment at the greater of 30% of the original book value of such equipment, and any associated upgrades to it, or 115% of the equipments net book value.

The Company believes that it has sufficient cash and investment balances to avoid the first triggering event under the supply agreement
with BASF for the foreseeable future. If a triggering event were to occur and BASF elected to proceed with the license and related sale mentioned above, the Company would receive royalty payments from this customer for products sold using the
Companys technology; however, the Company would lose both significant revenue and the ability to generate significant revenue to replace that which was lost in the near term. Replacement of necessary equipment that could be purchased and
removed by the customer pursuant to this triggering event could take in excess of twelve months. Any additional capital outlays required to rebuild capacity would probably be greater than the proceeds from the purchase of the assets as dictated by
the Companys agreement with the customer. Similar consequences would occur if the Company were determined to have materially breached certain other provisions of its supply agreement with BASF or the Companys technology development
agreement with Altana Chemie. Any such event would also result in the loss of many of the Companys key staff and line employees due to economic realities. The Company believes that its employees are a critical component of its success and
could be difficult to replace and train quickly. Given the occurrence of any such event, the Company might not be able to hire and retain skilled employees given the stigma relating to such an event and its impact on the Company.

(8) Business Segmentation and Geographical Distribution

Revenue from international sources approximated $229,000 and $248,000 for the three months ended March 31, 2010 and 2009,
respectively. As part of its revenue from international sources, the Company recognized approximately $152,000 in product revenue from several German companies and $75,000 in other revenue from a technology license fee from its Japanese licensee for
the three months ended March 31, 2010. Revenue from these same international sources approximated $171,000 and $75,000 for the same period in 2009.

The Companys operations comprise a single business segment and all of the Companys long-lived assets are located within the
United States.

(9) Recently Adopted Accounting Pronouncements

##### Table of Contents

In June 2009, the FASB issued ASC 105-10 (formerly SFAS No. 168), The FASB
Accounting Standards Codification and the Hierarchy of Generally Accepted Accounting Principles, which authorized the Codification as the sole source for authoritative U.S. GAAP. We adopted ASC 105-10 for the quarter ended
September 30, 2009. The adoption did not have an effect on our financial position or results of operations.

In
January 2010, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2010-06 Fair Value Measurements and Disclosures (Topic 820): Improving Disclosures about Fair Value Measurements(ASU 2010-06). ASU 2010-06 amends Accounting Standards Codification (ASC) 820 Fair Value Measurements and Disclosures to require new disclosures related to transfers into and out of Levels 1 and 2 of the fair
value hierarchy and additional disclosure requirements related to Level 3 measurements. The guidance also clarifies existing fair value measurement disclosures about the level of disaggregation and about inputs and valuation techniques used to
measure fair value. The additional disclosure requirements are effective for the first reporting period beginning after December 15, 2009, except for the additional disclosure requirements related to Level 3 measurements which are
effective for fiscal years beginning after December 15, 2010. Therefore, the additional disclosure requirements for 2010 have been taken into consideration and we do not believe the adoption of ASU No. 2010-06 will have a material
impact on our financial position or results of operations.

In February 2010, the FASB issued ASU 2010-09 Subsequent
Events (Topic 855): Amendments to Certain Recognition and Disclosure Requirements (ASU 2010-09). ASU 2010-09 amends ASC 855 Subsequent Events to no longer require public filers to disclose the date through which
subsequent events have been evaluated. We do not believe the adoption of ASU No. 2010-09 will have a material impact on our financial position or results of operations.



|Item 2. | Managements Discussion and Analysis of Financial Condition and Results of Operations
|------- | -------------------------------------------------------------------------------------

Overview

Nanophase is a
nanomaterials and applications developer and commercial manufacturer with an integrated family of nanomaterial technologies. Nanophase produces engineered nanomaterials for use in a variety of diverse markets: sunscreens, architectural coatings,
industrial coatings, ingredients, personal care, abrasion-resistant applications, plastics additives, medical diagnostics and a variety of polishing applications, including semiconductors, optics and window cleaning and polishing applications. We
target markets in which we feel practical solutions may be found using nanoengineered products. We work closely with current and potential customers in these target markets to identify their material and performance requirements and market our
materials to various end-use applications manufacturers. Newer developed technologies have made certain new products possible and opened potential new markets. We expect growth in end-user (customers of Nanophases customers) adoption in 2010
and beyond and revenue growth relative to these new markets to follow thereafter. We further expect that we will attract additional customers to help us achieve growth in certain markets in 2010 and beyond.

Results of Operations

Total revenue increased to $2,010,182 for the three months ended March 31, 2010, compared to $1,405,158 for the same period in 2009.
A substantial majority of our revenue for the three months ended March 31, 2010 is from our three largest customers. See Note 7 to the Financial Statements for additional information regarding the revenue derived from these three customers in
the first quarter of 2010. Product revenue increased to $1,930,602 for the three months ended March 31, 2010, compared to



11



---

##### Table of Contents

$1,296,813 for the same period in 2009. The increase in product revenue was primarily attributed to an increase in purchases from BASF, our largest customer. The Company and BASF Corporation
currently have a technology agreement in place that has led to the joint development of the second generation of certain sunscreen nanomaterials for other potential personal care applications.

Other revenue decreased to $79,580 for the three months ended March 31, 2010, compared to $108,345 for the same period in 2009. This
decrease was primarily attributed to deferred revenue associated with a customer note that was fully paid during 2009.

The
majority of the total revenue generated during the three months ended March 31, 2010 resulted from sales to our largest customer in healthcare for sunscreens components, as well as to our customer specializing in polishing applications.

Cost of revenue generally includes costs associated with commercial production and customer development
arrangements. Cost of revenue increased to $1,527,097 for the three months ended March 31, 2010, compared to $1,314,924 for the same period in 2009. The increase in cost of revenue was generally attributed to increased revenue volume, net of
efficiencies related to this increase in product flow. We expect to continue new nanomaterial development, primarily using our
NanoArc® synthesis and dispersion technologies, for targeted applications and new markets through 2010 and
beyond. At current revenue levels we have generated a positive gross margin. Our margins have been impeded by not having enough revenue to absorb the manufacturing overhead that is required to work with current customers and expected future
customers. We believe that our current fixed manufacturing cost structure is sufficient to support significantly higher levels of production, given current revenue mix and resultant product revenue. The extent to which our margins grow, as a
percentage of total revenue, will be dependent upon revenue mix, revenue volume, our ability to continue to cut costs and pass commodity market-driven raw materials increases on to customers. As product revenue volume increases, this should result
in more of our fixed manufacturing costs being absorbed, leading to increased margins. We expect to continue to focus on reducing controllable variable product manufacturing costs through 2010 and beyond, with potential offsetting increases in the
commodity metals markets, but may or may not continue to realize absolute dollar gross margin growth through 2010 and beyond, dependent upon the factors discussed above.

Research and development expense, which includes all expenses relating to the technology and advanced engineering groups, primarily
consists of costs associated with our development or acquisition of new product applications and coating formulations and the cost of enhancing our manufacturing processes. As an example, we have been, and continue to be, engaged in research to
enhance our ability to disperse material in a variety of organic and inorganic media for use as coatings and polishing materials, including window cleaning and polishing products. Much of this work has led to several new products and additional
potential new products.

Having demonstrated the capability to produce pilot quantities of mixed-metal oxides in a single
crystal phase, we do not expect development of further variations on these materials to present material technological challenges. Many of these materials exhibit performance characteristics that can enable them to serve in various catalytic
applications. We are now working on several related commercial opportunities using the same materials. We expect that this technique should enable us to scale to large quantity commercial volumes once application viability and firm demand are
established. We also have an ongoing advanced engineering effort that is primarily focused on the development of new nanomaterials as well as the refinement of existing nanomaterials, as dictated by our customer-driven marketing strategy. We are not
certain when or if any significant revenue will be generated from the production of the materials described above.

Research
and development expense increased to $429,263 for the three months ended March 31, 2010, compared to $404,044 for the same period in 2009. The increase in research and development



12



---

##### Table of Contents

expense was largely attributed to legal expenses associated with patent applications during the first quarter of 2010. We do not expect research and development expense to increase significantly
in 2010.

Selling, general and administrative expense increased to $1,212,417 for the three month period ended March 31,
2010, compared to $1,000,167 for the same period in 2009. The net increase was primarily attributed to a substantial non-cash charge related to outstanding equity compensation vehicles due to the increase in our share price during March 2010, as
well as legal fees related to the arbitration claim with Credit Suisse that was resolved by agreement entered into by the parties during March 2010.

Interest income decreased to $14,135 for the three month period ended March 31, 2010, compared to $34,003 for the same period in
2009. The decrease was primarily due to decreased investment yields and decreases in funds available for investment.

Inflation

We believe inflation has not had a material effect on our operations or financial position. However, supplier price
increases and wage and benefit inflation, both of which represent a significant component of our costs of operations, may have a material effect on our operations and financial position in 2010 and beyond if we are unable to pass through those
increases under our present contracts or through to our markets in general.

Liquidity and Capital Resources

Our cash, cash equivalents and investments amounted to $6,703,004 on March 31, 2010, compared to $7,493,997 on December 31, 2009
and $5,630,802 on March 31, 2009. The net cash used in our operating activities was $769,755 for the three months ended March 31, 2010, compared to $1,393,561 for the same period in 2009. Net cash used in investing activities, which is due
to maturities of securities and to a lesser extent capital expenditures offset partially by purchases of securities, amounted to $18,696 for the three months ended March 31, 2010 compared to net cash provided by $1,703,956 for the same period
in 2009. Capital expenditures amounted to $8,321 and $52,097 for the three months ended March 31, 2010 and 2009, respectively. Net cash used in financing activities is due to principal payments on an equipment loan from BYK-Chemie (2009 only)
and capital lease obligations amounting, in total, to $2,044 for the three months ended March 31, 2010 compared to $543,872 for the same period in 2009.

Our supply agreement with our largest customer contains several financial covenants which could potentially impact our liquidity. The
most restrictive financial covenants under this agreement require us to maintain a minimum of $2.0 million in cash and cash equivalents and not permit the acceleration of any debt maturity having a principal amount of more than $10,000,000, in order
to avoid triggering a transfer of technology and equipment to our largest customer. We had approximately $7 million in cash, cash equivalents and investments on March 31, 2010, with no debt. This supply agreement and its covenants are more
fully described in Note 7 to the Companys Financial Statements.

We believe that cash from operations and cash, cash
equivalents and investments on hand and interest income thereon, will be adequate to fund our operating plans for the foreseeable future. Our actual future capital requirements in 2010 and beyond will depend, however, on many factors, including
customer acceptance of our current and potential nanomaterials and product applications, continued progress in research and development activities and product testing programs, the magnitude of these activities and programs, and the costs necessary
to increase and expand our manufacturing capabilities and to market and sell our materials and product applications. Other important issues that will drive future capital requirements will be the development of new markets and new customers as well
as the potential for significant unplanned growth with existing customers. We expect that capital spending relating to currently known capital needs for the remainder of 2010 will be approximately $290,000, but could be even greater due to the
factors discussed above.

##### Table of Contents

On March 26, 2010, we entered into an agreement to sell our remaining auction rate
securities (ARS) for $4 million to Credit Suisse. This sale was completed and funds received on April 1, 2010.

Should events arise that make it appropriate for us to seek additional financing, such additional financing may not be available on
acceptable terms or at all, and any such additional financing could be dilutive to our stockholders. Such a financing could be necessitated by such things as the loss of existing customers; currently unknown capital requirements in light of the
factors described above; new regulatory requirements that are outside our control; the need to meet previously discussed cash requirements to avoid a triggering event under our BASF supply agreement; or various other circumstances coming to pass
that we currently do not anticipate.

On March 31, 2010, we had a net operating loss carryforward of approximately $80
million for income tax purposes. Because we may have experienced ownership changes within the meaning of the U.S. Internal Revenue Code in connection with our various prior equity offerings, future utilization of this carryforward may be
subject to certain limitations as defined by the Internal Revenue Code. A layer of our carryforward expired in 2009. If not utilized, the remaining carryforward will expire at various dates between January 1, 2010 and December 31, 2029. As
a result of the annual limitation and uncertainty as to the amount of future taxable income that will be earned prior to the expiration of the carryforward, we have concluded that it is likely that some portion of this carryforward will expire
before ultimately becoming available to reduce income tax liabilities.

OffBalance Sheet Arrangements

We have not created, and are not party to, any special-purpose or off-balance sheet entities for the purposes of raising capital,
incurring debt or operating our business. We do not have any off-balance sheet arrangements or relationships with entities that are not consolidated into our financial statements that are reasonably likely to materially affect our liquidity or the
availability of capital resources.

Credit Environment

The credit markets continue to be volatile and have experienced a shortage in overall liquidity due to the sub-prime lending industry. The
Company neither engages in any business activities in the mortgage industry, nor does it hold mortgage-backed securities in its investment portfolio. The Company believes it has sufficient liquidity from its cash and investment accounts to satisfy
2010 operational needs. See Notes 3 and 4 to the financial statements and Liquidity and Capital Resources in Managements Discussion and Analysis for a further discussion of liquidity issues.

Safe Harbor Provision

We want to provide investors with more meaningful and useful information. As a result, this Quarterly Report on Form 10-Q (the
Form 10-Q) contains and incorporates by reference certain forward-looking statements, as defined in Section 21E of the Securities Exchange Act of 1934, as amended. These statements reflect our current expectations
of the future results of our operations, performance and achievements. Forward-looking statements are covered under the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. We have tried, wherever possible, to identify
these statements by using words such as anticipates, believes, estimates, expects, plans, intends and similar expressions. These statements reflect managements current
beliefs and are based on information now available to it. Accordingly, these statements are subject to certain risks, uncertainties and contingencies that could cause our actual results, performance or achievements in 2010 and beyond to differ
materially from those expressed in, or implied by, such statements. These risks, uncertainties and factors include, without limitation: a decision by a customer to cancel a purchase order or supply agreement in light of our dependence on a limited
number of key customers; uncertain demand for, and
