EARTHSHELL CORPORATION

NOTES TO FINANCIAL STATEMENTS  (UNAUDITED)
SEPTEMBER 30, 1998
--------------------------------------------------------------------------------

1.     PRESENTATION OF FINANCIAL INFORMATION

       The foregoing financial information is unaudited and has been prepared
       from the books and records of EarthShell Corporation (the "Company"). In
       the opinion of management, the financial information reflects all
       adjustments necessary for a fair presentation of the financial condition,
       results of operations and cash flows in conformity with generally
       accepted accounting principles. All such adjustments were of a normal
       recurring nature for interim financial reporting.

       Certain information and footnote disclosures which were included in the
       Company's financial statements for the year ended December 31, 1997 have
       been condensed or omitted from this report. The information included in
       this Form 10-Q should be read in conjunction with Management's Discussion
       and Analysis and financial statements and notes thereto for the year
       ended December 31, 1997 included in the Company's Prospectus, dated March
       23, 1998.

       In addition, all references in the financial statements to number of
       shares outstanding and per share amounts of the Company's common and
       preferred stock have been restated to reflect a 262-for-one stock split
       (see Note 9).

       Certain reclassifications have been made to the 1997 financial statements
       to conform to 1998 classifications.

       Basic and diluted loss per common share is calculated based on weighted
       average shares outstanding of 99,883,320 and 94,178,427 for the three and
       nine months ended September 30, 1998, respectively, and 82,530,000 for
       the three and nine months ended September 30, 1997, respectively. Basic
       and diluted are the same because common stock equivalents are considered
       anti-dilutive.

2.     CASH AND CASH EQUIVALENTS

       Cash and cash equivalents include cash, funds invested in money market
       mutual funds and cash invested temporarily in various instruments with
       maturities of three months or less at the time of purchase. The carrying
       value of cash equivalents approximates fair value. The money market
       mutual fund deposits have an investment objective to provide high current
       income to the extent consistent with the preservation of capital and the
       maintenance of liquidity.

       At March 30, 1998, a certificate of deposit for $3,500,000 was opened as
       collateral on the letter of credit related to the Company's obligation
       under a letter agreement between E. Khashoggi Industries, LLC, the 
       Company's majority stockholder ("EKI"), and the Company relating to a 
       patent purchase agreement between EKI and a third party as discussed in 
       Note 7 and is classified as restricted cash on the balance sheet.

3.     SHORT-TERM INVESTMENTS

       Investments are accounted for in accordance with Statement of Financial
       Accounting Standards No. 115 and are classified as available for sale.
       This standard requires that certain debt and equity securities be
       adjusted to market value at the end of each accounting period. Unrealized
       gains and losses are charged or credited to a separate component of
       stockholders' equity. At September 30, 1998, the market value of
       short-term investments approximates cost.

       and EKI and $16,800 and $50,400 in sublease payments to EKI for each

       ("Patent Cost Allocation Agreement") effective October 1, 1997, legal
       fees related to patents of $33,024 and $70,997 were paid to or on behalf

       respectively, and $118,125 and $551,370 for the nine months ended
       September 30, 1998 and 1997, respectively.

       The Company repaid the total indebtedness to its majority stockholder

       On February 16, 1998, EKI entered into certain agreements with an 
       equipment manufacturer providing for the purchase by EKI of certain 
       technology applicable to starch-based disposable packaging. EKI 
       licenses such technology to the Company on a royalty-free basis 
       pursuant to the Amended and Restated License Agreement dated February 
       28, 1995, as amended. In connection with the purchase, and pursuant to 
       the terms of the Patent Cost Allocation Agreement, the Company agreed 
       to pay the seller of the technology $3,500,000 on or about December 
       31, 2003, which obligation is secured by a letter of credit.

       The Company's obligation will be reduced by 5% of the purchase price of
       any equipment purchased by EKI, the Company or its licensees or joint
       venture partners from the seller of the technology. In addition, the
       Company is required to pay $3,000,000 over the five year period
       commencing January 1, 2004 if EKI, the Company or the Company's licensees
       or joint venture partners have not purchased, by December 31, 2003, at
       least $35,000,000 of equipment from the seller of the technology and EKI,
       the Company or the Company's licensees or joint venture partners make
       active use of the purchased technology. EKI has agreed to indemnify the
       Company to the extent the Company is required to pay any portion of this
       $3,000,000 obligation solely as a result of EKI's or its licensees'
       active use of such patents and related technology (other than use by the
       Company or its sublicensees).

8.     COMMON STOCK OFFERING

       Pursuant to the Company's prospectus dated March 23, 1998, on March 27,
       1998, the Company issued an additional 10,526,316 shares of its common
       stock in a public offering for $205,873,995 after deducting underwriting

       On March 23, 1998, the Company declared a 262-for-one stock split of its
       common stock. Common stock and additional paid-in common capital have
       been restated to reflect this split. The par value of the common stock
       remained unchanged at $.01 per share. In accounting for the stock split,
       the Company recorded an increase in common stock of $822,150, with a
       corresponding reduction in additional paid in common capital. The number
       of shares issued and outstanding at December 31, 1997, after giving
       effect to the split, was 82,530,000 (315,000 shares were issued and
       outstanding before the stock split and common stock offering).

10.    CUMULATIVE CONVERTIBLE PREFERRED STOCK

       To facilitate the sale by stockholders of Series A preferred stock in the
       initial public offering of common stock, 3,993,404 shares of the
       6,988,850 shares of outstanding Series A preferred stock were converted
       to 3,993,404 shares of common stock, on a post-split basis. A portion of
       the converted shares was sold in the initial public offering by
       stockholders.

       The other 2,995,446 shares of Series A preferred stock remained 
       convertible to common stock after the initial public offering. In the 
       Company's Prospectus dated March 23, 1998, the Company disclosed its 
       intent to redeem all Series A preferred stock shortly following the 
       initial public offering. In anticipation of the preferred stock 
       redemption, on April 15, 1998, the Board of Directors declared a cash 
       dividend to preferred stockholders of $1.40 per share based on the 
       dividend rate of 8% per annum on the liquidation preference of the 
       shares. The total dividends paid were $9,725,201. By notice dated May 
       13, 1998, the Company called for redemption, effective July 14, 1998, 
       the remaining 2,995,446 shares of Series A preferred stock. On August 
       6, 1998, the Board of Directors declared a cash dividend to former 
       preferred stockholders of $.0033 per share based on the dividend rate 
       of 8% per annum of the liquidation preference pursuant to the 
       Certificate of Designation, Preferences Relative, Participating, 
       Optional and Other Special Rights for Series A Cumulative Senior 
       Convertible Preferred Stock, which provides for dividends to accrue 
       until the time of conversion, together with interest thereon at the 
       rate of 8% per annum from the date of conversion until the date of 
       payment. Total dividends and interest paid on September 17, 1998 
       amounted to $201,502. As of September 30, 1998, all outstanding shares 
       of Series A preferred stock had been converted to common stock.

11.    STOCK OPTIONS

       During the second and third quarters of 1998, options to purchase 
       660,000 shares were granted to certain officers and employees at an 
       exercise price of $21.00 per share. These options vest equally over four
       years from the date of the grant. Stock option activity was as follows:

ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS

Any statements in this quarterly report concerning the Company's business
outlook or future economic performance; anticipated profitability, revenues,
expenses or other financial items; together with other statements that are not
historical facts, are "forward-looking statements" as that term is defined under
the Federal Securities Laws. Forward-looking statements are subject to risks,
uncertainties and other factors that could cause actual results to differ
materially from those stated in such statements. The Company's financial
condition and the results of its operations are subject to a number of factors
that are set forth in the prospectus filed with the Company's Registration
Statement on Form S-1 (Commission File No. 333-13287; effective March 23, 1998),
(the "Prospectus") and should be read in conjunction with this quarterly report.

RESULTS OF OPERATIONS

OVERVIEW

The Company was organized in November 1992 as a Delaware corporation and 
remains a development stage enterprise. EKI, the Company's principal 
stockholder, or its predecessor, has been involved since July 1985 in the 
development of various new material technologies. The Company was formed to 
develop, license and commercialize food service disposables made of 
EarthShell composite material ("EarthShell Products"). The Company has an 
exclusive, worldwide, royalty-free license from EKI to use certain technology 
for this purpose. The Company intends to license or joint venture with 
existing manufacturers of food service disposables for the manufacture and 
distribution of EarthShell Products. The Company expects to derive revenues 
primarily from license royalties and distributions from joint ventures that 
are licensed to manufacture EarthShell Products.

DEVELOPMENT OF FIRST COMMERCIAL MANUFACTURING FACILITY

One of the Company's licensees, Sweetheart Cup Company Inc. ("Sweetheart"), 
has secured a contract with Perseco (McDonald's Corporation's primary 
packaging purchasing agent), to supply McDonald's US restaurants with a 
minimum of 1.8 billion Big Mac sandwich containers made from the EarthShell 
material over a three-year period. To support this initial commercial 
EarthShell application, EarthShell has agreed with Sweetheart to provide 
manufacturing equipment to Sweetheart with adequate capacity to fulfill the 
Perseco/McDonald's order.

In cooperation with Sweetheart, the Company has engaged The Food Group, a 
division of CH2M Hill, to provide detailed engineering, procurement and 
construction management services relating to the installation of three 
commercial sandwich container production lines at Sweetheart's Owings Mills, 
Maryland facility. These lines have been designed to enable Sweetheart to 
produce Big Mac sandwich containers in sufficient quantities to fulfill 
Sweetheart's supply agreement with Perseco. The development and installation 
of equipment lines at this facility has been the Company's major focus since 
Sweetheart secured the Perseco supply agreement relating to Big Mac sandwich 
containers in October 1997. The Company anticipates that it will begin 
start-up and debugging of the first line before year-end.

As the Owings Mills facility is the first commercial production of the 
EarthShell technology, the Company believes that the cost incurred on these 
first lines is significantly higher than the cost of subsequent lines. At the 
time of the initial public offering, the Company estimated that the cost 
associated with the initial installation at Sweetheart, if approximately $19 
million in costs that were estimated for initial development and engineering 
of commercial scale production capability are included, would be between $25 
million and $30 million.

Management now estimates that the capitalized cost of the first three lines,
including infrastructure improvement not reimbursed by Sweetheart, will
approximate $36 million at completion. In addition, the 

                                       10
<PAGE>

Company expects to expense approximately $7 million of process development, 
design and engineering costs. The Company also anticipates incurring 
approximately $3.5 million of cost associated with future lines at Owings 
Mills.

The Company believes a significant portion of the incremental capitalized 
cost of the Sweetheart installation is non-recurring. These non-recurring 
costs include portions of plant engineering and design costs, expediting 
premiums to meet the customer's timetable, oversizing of system components to 
allow for margins of safety or capacity flexibility, instrumentation and 
monitoring equipment to provide input for future value engineering, and 
premiums paid on component equipment for first time, single item purchases. 
The Company believes these factors account for the higher than anticipated 
capital cost of its first commercialization. The Company also believes 
manufacturing process design and development expenses will be reduced in 
future sites. Based on internal analysis, and supported by external 
engineering studies, the Company believes that future results in the 
relationship between capital cost and the level of revenue dollars that are 
generated by its licensees or joint venture partners will meet, and then 
exceed industry norms. Based on vendor trials of the actual commercial 
machinery components of the first manufacturing line, the Company believes 
that the first three commercial lines will meet or exceed the total 
throughput specified in the original four line design basis, and will meet or 
exceed the requirements of its first customer, McDonald's.

With respect to future lines at the Owings Mills site, the Company is 
confident that an agreement can be concluded with Sweetheart to build the 
additional lines.

OTHER CUSTOMERS AND LICENSEES

In addition to discussions with Sweetheart, the Company is engaged in 
discussions with additional converters for the creation of new licensing or 
joint venture agreements to further commercialize its technology. On October 
26, 1998 the Company announced it signed a letter of intent to establish a 
joint venture to commercialize EarthShell Products throughout Europe, Asia 
(except Japan), Australia and New Zealand with Huhtamaki Oyj, a leading 
international food and food packaging firm headquartered in Finland which 
commands leading market shares in several of the major markets of Europe, 
Asia and Australia. The Company also announced on November 9, 1998 that it 
had signed a letter of intent with Prairie Packaging Inc. ("Prairie") to 
establish production of an array of products. The proposed arrangement 
encompasses the production of plates, hinged lid containers and cups, 
initially to be sold to Sysco Corporation, the leading food service 
distributor in North America. Based on these letters of intent, the Company 
has initiated engineering design work for the next commercial installations 
that will manufacture a broadened commercial product set.

While the Company intends to use its best efforts to enter into definitive
agreements based on these letters of intent with Huhtamaki Oyj and Prairie,
there can be no assurance that such definitive agreements will be entered into.

TRANSITION ACTIVITIES IN PREPARATION FOR MANUFACTURING RAMP-UP

The Company is transitioning from being a development stage company primarily 
engaged in product development to a company engaged in licensing and 
supporting the commercial implementation of its technology. Concurrent with 
the development of the first commercial EarthShell production facility and in 
response to anticipated market demand, the Company is planning and preparing 
for the rapid growth.

During the second and third quarters of 1998, the Company hired several senior
executives to expand core competencies and fill critical on-going positions:
William F. McLaughlin, President and Chief Operating Officer; William F.
Spengler, Senior Vice President of Corporate Planning and Business Development;
Vincent J. Truant, Vice President of Marketing, Sales and Public Relations; and
Michael M. Hagerty, Vice President and Chief Technology Officer. These hirings
reflect the Company's intensified efforts to build a 

                                       11
<PAGE>

highly experienced management team to execute the Company's strategy and 
enhance the creation of shareholder value. It is anticipated that additional 
employees will be hired during the next six months in the areas of 
manufacturing process and product development, construction management, 
marketing and finance.

To better address and service the geographical concentration of the Company's
initial and anticipated commercial activities and to minimize projected
operating costs, the Company's corporate headquarters has been relocated to
Baltimore, Maryland from Santa Barbara, California. Accordingly, the Company has
entered into a long-term lease agreement for office space in downtown Baltimore
where the Company's senior management team will be located. The Company has also
decided to transition its product development center to the Baltimore region to
be closer to the Company's headquarters. Basic research activities, which will
continue to be supported by the EKI technical staff, will remain in the Santa
Barbara, California area.

During the third quarter of 1998, the Company also concluded a strategic 
business planning review with the Boston Consulting Group and has further 
developed its execution strategy to exploit its food service disposable 
technology on a global basis.

COMPARISON OF THE THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30, 1998, TO THE
THREE MONTHS AND NINE MONTHS ENDED SEPTEMBER 30, 1997

RESEARCH AND DEVELOPMENT EXPENSES. Total research and development 
expenditures for the development of EarthShell Products increased $6.5 
million to $12.8 million from $6.3 million for the nine months ended 
September 30, 1998 compared with the nine months ended September 30, 1997, 
and increased $2.7 million to $4.7 million from $2.0 million for the three 
months ended September 30, 1998 compared with the three months ended 
September 30, 1997. The increase in the nine month period was anticipated as 
part of the Company's commercialization activities and was due primarily to 
$3.4 million in design and engineering fees and $1.8 million in abandoned 
early generation prototype equipment related to the development of the 
Company's first commercial manufacturing line. The increase in the three 
month period was due primarily to planned increases in continuing support of 
commercializing the EarthShell Products. The Company was billed by EKI for 
research and development services totaling $6.3 million for the nine months 
ended September 30, 1998 and $5.6 million for the nine months ended September 
30, 1997 and $2.5 million and $1.7 million for each of the three months ended 
September 30, 1998 and 1997, respectively.

OTHER GENERAL AND ADMINISTRATIVE EXPENSES. When comparing the nine months ended
September 30, 1998 to the nine months ended September 30, 1997 other general and
administrative expenses increased $4.9 million to $6.3 million from $1.4
million. Approximately $3.3 million was due to planned executive staffing
additions and start-up activities related to the new Baltimore headquarters,
$1.3 million was due to strategic business planning efforts with the Boston
Consulting Group and $0.2 million was due to planned increases in various
insurance coverages.

When comparing the three months ended September 30, 1998 to the three months
ended September 30, 1997 other general and administrative expenses increased
$3.7 million to $4.2 million from $0.5 million. Approximately $2.6 million was
due to planned executive staffing additions and start-up activities related to
the new Baltimore headquarters, $1.0 million was due to strategic business
planning efforts with the Boston Consulting Group, and $0.1 million was due to
planned increases in various insurance coverages.

DEPRECIATION AND AMORTIZATION EXPENSE. Depreciation and amortization expense
increased $244,000 to $613,000 from $369,000 for the nine months ended September
30, 1998 compared with the nine months ended September 30, 1997, and increased
$93,000 to $225,000 from $132,000 for the three months ended September 30, 1998
compared with the three months ended September 30, 1997. The increase in

                                       12
<PAGE>

depreciation expense was primarily the result of the purchase of pilot
manufacturing equipment for the Company's product development center.

As the commercial manufacturing equipment is being installed at Sweetheart, it
is anticipated that depreciation and amortization will increase significantly
when the equipment is placed in service.

RELATED PARTY PATENT EXPENSES. Legal fees reimbursed to EKI under the Amended
and Restated Agreement for Allocation of Patent Costs with EKI decreased
$433,000 to $118,000 from $551,000 for the nine months ended September 30, 1998
compared with the nine months ended September 30, 1997, and decreased $38,000 to
$33,000 from $71,000 for the three months ended September 30, 1998 compared with
the three months ended September 30, 1997. The decrease was primarily a result
of filing fewer new patent applications than the previous period.

INTEREST INCOME. Interest income was $1.7 million and $3.6 million for the three
and nine months ended September 30, 1998, respectively, and reflects investment
earnings on the net proceeds of the Company's initial public offering completed
at the end of March 1998. The Company's investment policy requires that the
proceeds from the initial public offering be invested in investment grade money
market instruments with average maturities of less than one year.

INTEREST EXPENSE. Interest expense decreased $1.3 million to $1.1 million from
$2.4 million for the nine months ended September 30, 1998 compared with the nine
months ended September 30, 1997, and decreased $0.8 million to zero from $0.8
million for the three months ended September 30, 1998 compared with the three
months ended September 30, 1997. Following the initial public offering in March
1998, a majority of the outstanding debt was repaid. As a result, interest
expense was minimal in the second and third quarters of 1998.

LIQUIDITY AND CAPITAL RESOURCES AT SEPTEMBER 30, 1998

Pursuant to the Company's prospectus dated March 23, 1998, on March 27, 1998, 
the Company issued 10.5 million shares of its common stock in a public 
offering in which the Company received $205.9 million net of issuance costs. 
A portion of the proceeds was used to repay indebtedness to the majority 
stockholder of $36.6 million and bank debt of $14.0 million. The remaining 
proceeds are being used to: (i) facilitate the development of 
manufacturing capacity for the Company's products by engineering, developing 
and constructing manufacturing lines for lease to licensees or contribution 
to joint ventures; (ii) expand the EarthShell product development center; 
(iii) launch an initial public relations campaign; (iv) secure additional 
patent protection for the Company's licensed technology; and (v) for general 
corporate purposes, including the employment of additional personnel, the 
continued design and development of EarthShell Products and anticipated 
operating losses. As of September 30, 1998 the Company had cash and 
short-term investments of $114.2 million. During the remainder of 1998, the 
Company expects to incur operating expenses significantly in excess of 
amounts incurred in prior years based on the Company's operating plans as 
discussed in Results of Operations above.

Net cash used in operations was $36.8 million and $2.9 million for the nine
months ended September 30, 1998 and 1997, respectively. Net cash used in
investing activities was $31.8 million and $48,000, for the nine months ended
September 30, 1998 and 1997, respectively. In addition to the repayment of
indebtedness, the Company used the public offering proceeds to repay outstanding
payables and purchase equipment to facilitate the development of manufacturing
capacity for EarthShell Products.

Subsequent to December 31, 1997 and prior to the public offering, the Company
borrowed an additional $1.5 million and $2.2 million from its majority
stockholder and its credit line bank, respectively. These additional borrowings
were repaid on March 27, 1998.

The Company has been advised by its software vendors that the release/version of
the software being implemented or used by the Company is Year 2000 compliant.
Therefore, the Company believes that the cost of completing any modifications
necessary to become Year 2000 compliant will not be material. There can be no
assurance, however, that the Company will be able to identify all aspects of its
business that are subject to Year 2000 problems, or identify Year 2000 problems
of customers or suppliers that affect the Company's business. There also can be
no assurance that the Company's software vendors are correct in their
assertions, or that the Company's estimate of the cost of systems preparation
for Year 2000 compliance will ultimately prove to be accurate.

The Company anticipates that it will borrow from third-party lenders a portion
of the funds required to purchase manufacturing equipment and construct
manufacturing lines for its licensee and joint venture partners. The Company
believes that the remaining proceeds from the initial public offering together
with such third party financing will be sufficient to meet its foreseeable
working capital requirements through at least the next 12 months.

The Company has no commitments for any additional financing, and there can be no
assurance that any such commitments can be obtained on favorable terms, if at
all. If the Company is unable to obtain additional financing as needed after
demonstrating the commercial viability of its manufacturing equipment, the
Company may be required to reduce the scope of its anticipated manufacturing
ramp-up and products introduction, which could have an adverse effect on the
Company's business, financial condition and results of operations.

                           PART II. OTHER INFORMATION

ITEM 2.  CHANGES IN SECURITIES AND USE OF PROCEEDS

CHANGES IN SECURITIES -

Effective March 27, 1998, the number of authorized common shares increased 
from 1,000,000 to 200,000,000 and the number of authorized preferred shares 
increased from 100,000 to 10,000,000. On that day, the Company issued an 
additional 10,526,316 shares of its common stock in a public offering in 
which the Company received $205,873,995, net of issuance costs. In addition, 
the Company declared a 262-for-one stock split of its common stock. 
Furthermore, in connection with the Company's public offering of common 
stock, selling stockholders sold 2,673,684 shares of common stock. After 
giving effect to the split, 3,993,404 shares of Series A Preferred Stock were 
converted to common stock to allow for the sale of stock by preferred 
stockholders. The Company did not receive any proceeds from the sale of 
common stock by the selling stockholders.

In the Company's Prospectus dated March 23, 1998, the Company disclosed its 
intent to redeem all Series A convertible preferred stock shortly following 
the initial public offering. By notice dated May 13, 1998, the Company called 
for redemption, effective July 14, 1998, of the remaining 2,995,446 shares of 
Series A preferred stock. As of September 30, 1998, all outstanding shares of 
Series A Preferred Stock had been converted to common stock.

All stockholders who were not selling stockholders in the Company's initial
public offering (other than one stockholder who owns 262 shares of common
stock), including all officers, directors or affiliates, entered into agreements
with the underwriters of the offering, in which such stockholders agreed,
subject to certain exceptions, not to sell or otherwise dispose of any shares of
common stock for a period of 180 days from March 27, 1998 (the closing date of
the offering) without the prior written consent of Salomon Brothers Inc., an
affiliate of Smith Barney Inc. This 180 day period expired on September 22,
1998, at which time (i) non-selling stockholders holding 7,384,732 shares of
common stock were free of any restrictions under such agreements and free of any
resale limitations under Rule 144 and (ii) affiliates of the company holding
73,464,800 shares of Common Stock, 73,398,252 shares of which are held by E.
Khashoggi Industries, LLC or its affiliates, were also free of any restrictions
under such agreements, but remain subject to the resale limitations set forth in
Rule 144. All stockholders who were selling shareholders in the initial public
offering entered into similar agreements with the underwriters of the offering
not to sell or otherwise dispose of any shares of common stock for a period of
270 days from the close of the offering without prior written consent. This 270
day period expires December 22, 1998 at which time stockholders holding
4,965,006 shares of common stock may sell shares free of any restrictions under
such agreements and free of any resale limitations under Rule 144. The Company
is unable to estimate the number of shares that may be sold by such stockholders
after December 22, 1998 or the effect, if any, that sales of shares by such
stockholders will have on the market price of the common stock prevailing from
time to time. Sales of substantial amounts of shares of common stock by such
stockholders could adversely effect prevailing market prices.

USE OF PROCEEDS -

As part of the Company's initial public offering, the Company issued 10,526,316
shares of its common stock, $.01 par value (the "IPO Shares"), on March 27,
1998. The offering terminated on April 23, 1998 upon the underwriters' election
not to exercise their overallotment option. The IPO Shares were issued in a
registered offering pursuant to a Registration Statement on Form S-1 (Commission
File No. 333-13287; effective March 23, 1998) through a syndicate of
underwriters, the representatives of which were Salomon Smith Barney Inc. and
Credit Suisse First Boston Corporation. The IPO Shares were offered and sold by
the underwriters at an initial public offering price of $21.00 per share,
resulting in aggregate offering proceeds of $221,052,636.
