<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Basis of Presentation</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the opinion of management, the unaudited consolidated financial statements reflect all
adjustments, consisting only of normal recurring adjustments, necessary for their fair presentation
in conformity with accounting principles generally accepted in the United States of America.
Certain information and footnote disclosures normally included in annual financial statements have
been condensed or omitted in accordance with the rules and regulations of the Securities and
Exchange Commission. The information included in this Form 10-Q should be read in conjunction with
Management&#146;s Discussion and Analysis of Financial Condition and Results of Operations and financial
statements and notes thereto included in the Company&#146;s Annual Report on Form 10-K for the fiscal
year ended September&nbsp;30, 2004.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Reclassification</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Certain reclassifications have been made to prior year balances to conform to the current
period presentation. Specifically, the Company&#146;s U.S. deferred tax liabilities have been
reclassified and presented net of U.S. deferred tax assets in accordance with the provisions of
Statement of Financial Accounting Standards No.&nbsp;109, &#147;Accounting for Income Taxes.&#148; The
reclassifications had no impact on previously reported net income or shareholders&#146; equity.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Revenue Recognition</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company recognizes revenue in accordance with the guidance provided under Statement of
Position (SOP)&nbsp;No.&nbsp;97-2, &#147;Software Revenue Recognition,&#148; and SOP No.&nbsp;98-9 &#147;Modification of SOP No.
97-2, Software Revenue Recognition, with Respect to Certain Transactions,&#148; Statement of Financial
Accounting Standards (SFAS)&nbsp;No.&nbsp;48, &#147;Revenue Recognition When Right of Return Exists,&#148; and SEC
Staff Accounting Bulletin (SAB)&nbsp;No.&nbsp;104, &#147;Revenue Recognition.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company sells products through distributors, resellers, and directly to end users. The
Company recognizes product revenue upon shipment, net of estimated returns, provided that
collection is determined to be probable and no significant obligations remain. In certain regions
where the Company does not have the ability to reasonably estimate returns, the Company defers
revenue on sales to its distributors until the Company has received information from the channel
partner indicating that the distributor has sold the product to its customer. Payment terms to
domestic customers are generally net 30&nbsp;days. Payment terms to international customers range from
net 30 to 90&nbsp;days based on normal and customary trade practices in the individual markets. The
Company has offered extended payment terms ranging from three to six months to certain customers,
in which case, revenue is recognized when payments are made.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Whenever a software license, hardware, installation and post-contract customer support, or
PCS, elements are sold together, a portion of the sales price is allocated to each element based on
their respective fair values as determined when the individual elements are sold separately.
Revenues from the license of software are recognized when the software has been shipped and the
customer is obligated to pay for the software. When rights of return are present and the Company
cannot estimate returns, the Company recognizes revenue when such rights of return lapse. Revenues
for PCS are recognized on a straight-line basis over the service contract term. PCS includes rights
to

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Goodwill represents the excess purchase price over the estimated fair value of net assets
acquired as of the acquisition date. The Company has adopted the requirements of Statement of
Financial Accounting Standards No.&nbsp;142, &#147;Goodwill and Other Intangible Assets&#148; (SFAS No.&nbsp;142). SFAS
No.&nbsp;142 requires goodwill to be tested for impairment on an annual basis and between annual tests
in certain circumstances, and written down when impaired. Goodwill of $24.2&nbsp;million was recorded in
connection with the acquisition of uRoam, Inc. in July&nbsp;2003. Additional goodwill of $25.9&nbsp;million
was recorded as a result of the MagniFire acquisition on May&nbsp;31, 2004. The Company concluded that
there was no impairment of goodwill during the nine months ended June&nbsp;30, 2005 and 2004,
respectively.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Stock-Based Compensation</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company accounts for stock-based employee compensation arrangements in accordance with the
provisions of Accounting Principles Board Opinion No.&nbsp;25 (&#147;APB No.&nbsp;25&#148;), &#147;Accounting for Stock
Issued to Employees,&#148; FASB Interpretation No.&nbsp;44 (&#147;FIN No.&nbsp;44&#148;) &#147;Accounting for Certain

disclosure provisions of Statement of Financial Accounting Standards No.&nbsp;123 (&#147;SFAS No.&nbsp;123&#148;),
&#147;Accounting for Stock-Based Compensation.&#148; Under APB No.&nbsp;25, compensation expense is based on the
difference, if any, on the date of the grant, between the fair value of our stock and the exercise
price of the option. Unearned compensation is amortized in accordance with Financial Accounting
Standards Board Interpretation No.&nbsp;28 on an accelerated basis over the vesting period of the
individual options.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Pro forma information regarding net income is required by SFAS No.&nbsp;123 and has been determined
as if the Company had accounted for stock options under the fair value method. For purposes of pro
forma disclosures, the estimated fair value of the options is amortized over the options&#146; vesting
period. The net income and net income per share would have been adjusted to the pro forma amounts
indicated below (in thousands, except per share data):

options for the three and nine months ended June&nbsp;30, 2005 and 2004, respectively, are excluded

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In March&nbsp;2004, the Emerging Issues Task Force (&#147;EITF&#148;) reached a consensus on Issue No.&nbsp;03-1,
&#147;The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments.&#148; EITF
03-1 provides guidance on other-than-temporary impairment models for marketable debt and equity
securities accounted for under SFAS No.&nbsp;115, &#147;Accounting for Certain Investments in Debt and Equity
Securities,&#148; and SFAS No.&nbsp;124, &#147;Accounting for Certain Investments Held by Not-for-Profit
Organizations,&#148; and non-marketable equity securities accounted for under the cost method. The EITF
developed a basic three-step model to evaluate whether an investment is other-than-temporarily
impaired. On September&nbsp;30, 2004, the FASB approved the issuance of FASB Staff Position (FSP)&nbsp;EITF
03-1-1, which delays the effective date until additional guidance is issued for the application of
the recognition and measurement provisions of EITF 03-1 to investments in securities that are
impaired. The Company does not expect the adoption of EITF 03-1 to have a material effect on the
Company&#146;s results of operations or financial condition.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In December&nbsp;2004, the FASB issued SFAS 123(R), &#147;Share-Based Payment.&#148; This Statement revises
FASB Statement No.&nbsp;123, &#147;Accounting for Stock-Based Compensation&#148; and supersedes APB Opinion No.
25, &#147;Accounting for Stock Issued to Employees.&#148; Among other items, SFAS 123(R) eliminates the use
of APB 25 and intrinsic value method of accounting, and requires companies to recognize the cost of
employee services received in exchange for awards of equity instruments, based on the grant date
fair value of those awards, in the financial statements. While the Company is not required to
adopt SFAS 123(R) until the first quarter of fiscal 2006, it has elected to early-adopt the
statement effective July&nbsp;1, 2005, using the modified prospective method of application. Under this
method, in addition to reflecting compensation expense for new share-based awards, expense will be
recognized to reflect the remaining vesting period of awards that had been included in pro-forma
disclosures in prior periods. The Company expects to recognize pre-tax stock-based compensation
costs of $5.2&nbsp;million ($3.3&nbsp;million net of tax) in the fourth quarter of fiscal 2005. The Company
will not adjust prior period financial statements under the optional modified retrospective methods
of adoption.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In May of 2005, the FASB issued SFAS No.&nbsp;154, &#147;Accounting Changes and Error Corrections &#151; A

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In the normal course of business to facilitate sales of its products, the Company indemnifies
other parties, including customers, resellers, lessors, and parties to other transactions with the
Company, with respect to certain matters. The Company has agreed to hold the other party harmless
against losses arising from a breach of representations or covenants, or out of intellectual
property infringement or other claims made against certain parties. These agreements may limit the
time within which an indemnification claim can be made and the amount of the claim. In addition,
the Company has entered into indemnification agreements with its officers and directors, and the
Company&#146;s bylaws contain similar indemnification obligations to the Company&#146;s agents. It is not
possible to determine the maximum potential amount under these indemnification agreements due to
the limited history of prior indemnification claims and the unique facts and circumstances involved
in each particular agreement.

additional warranty coverage generally in yearly increments. The Company accrues for warranty costs
as part of its cost of sales based on associated material product costs and technical support labor
costs. The following table summarizes the activity related to product warranties during the three

manufacture of the Company&#146;s products. The arrangement with the primary contract manufacturer
allows them to procure component inventory on the Company&#146;s behalf based on a rolling production
forecast provided by the Company. The Company is obligated to the purchase of component inventory
that the contract manufacturer procures in accordance with the forecast, unless cancellation is
given outside of applicable lead times. As of June&nbsp;30, 2005, the Company was committed to purchase
approximately $9.9&nbsp;million of such inventory over the next quarter.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;During the fiscal year 2002, the Company executed on a restructuring plan that included the
discontinuation of its cache appliance business. As a result of discontinuing this line of
business and other changes in the overall business, the Company incurred restructuring charges of
$3.3&nbsp;million for the fiscal year 2002. The restructuring charges included employee termination
benefits, impaired assets, consolidation of excess facilities, and other obligations for which the
Company no longer derives an economic benefit. There were no restructuring charges for the three
months or nine months ended June&nbsp;30, 2005 and 2004.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The activity of the remaining restructuring liability included as a component of accrued
liabilities on the balance sheet for the nine months ended June&nbsp;30, 2005 is presented below (in

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The excess facilities charge was the result of the Company&#146;s decision to exit its support
facility in Washington, D.C. and was estimated based on current comparable rates for leases in the
respective market. In April&nbsp;2003, the excess facilities were subleased at the then current market
value. Since then the difference between the lease payments and sublease income has historically
been applied against the restructuring liability. During the nine months ended June&nbsp;30, 2005,
timely receipts of sublease income were not received and the collectibility of sublease income is
uncertain. If we are unable to collect further sublease income throughout the duration of the
lease term, expiring in 2007, the actual loss may be increased from the original estimate and an
additional restructuring charge may be required.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company&#146;s customers are in diverse industries and geographic locations. Net revenues from
international customers are primarily denominated in U.S. dollars and totaled approximately $26.1
million and $16.5&nbsp;million for the three months ended June&nbsp;30, 2005 and 2004 respectively, and $81.1
million and $47.1&nbsp;million for the nine months ended June&nbsp;30, 2005 and 2004, respectively. One
domestic distributor accounted for 22.7% and 19.9% of total net revenue for the three months ended
June&nbsp;30, 2005 and 2004, respectively. This distributor accounted for 19.0% and 17.5% of
total net revenue for the nine months ended June&nbsp;30, 2005 and 2004, respectively. This distributor
also accounted for 31.1% of accounts receivable as of June&nbsp;30, 2005 and 26.9% as of September&nbsp;30,
2004.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following Management&#146;s Discussion and Analysis of Financial Condition and Results of
Operations should be read in conjunction with our consolidated financial statements and notes
thereto contained in the Company&#146;s Annual Report on Form 10-K filed with the Securities and
Exchange Commission on December&nbsp;7, 2004. Our discussion may contain forward-looking statements,
within the meaning of the Private Securities Litigation Reform Act of 1995, based upon current
expectations. These forward-looking statements include, but are not limited to, statements about
our plans, objectives, expectations and intentions and other statements that are not historical
facts. Because these forward-looking statements involve risks and uncertainties, our actual
results and the timing of certain events could differ materially from those anticipated in these
forward-looking statements as a result of certain factors, including those set forth under &#147;Risk
Factors&#148; and &#147;Business&#148; in the Company&#146;s Annual Report on Form 10-K for the fiscal year ended
September&nbsp;30, 2004, and elsewhere in this report.

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Overview</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are a global provider of software and hardware products and services that help companies
efficiently and securely manage their Internet traffic. Our products enhance the delivery,
optimization and security of application traffic on Internet-based networks. We market and sell
our products primarily through indirect sales channels in the Americas, Europe, Japan and the Asia
Pacific regions. Enterprise customers (Fortune 1000 or Business Week Global 1000 companies) in
financial services, transportation, government and telecommunications industries continue to make
up the largest percentage of our customer base.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our management monitors and analyzes a number of key performance indicators in order to manage
our business and evaluate our financial and operating performance. Those indicators include:
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%"><I><B>&#149;</B> Revenues. </I>The majority of our revenues are derived from sales of our core products;
BIG-IP Local Traffic Manager; BIG-IP Global Traffic Manager; BIG-IP ISP Traffic Manager;
TrafficShield Application Firewall, and FirePass SSL VPN servers. We also derive revenues
from the sales of services including annual maintenance contracts, installation, training and
consulting services. We carefully monitor the sales mix of our revenues within each
reporting period. We believe customer acceptance rates of our new products and feature
enhancements are key indicators of future trends. We also consider overall revenue
concentration by customer and by geographic region as additional indicators of current and
future trends.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%"><I><B>&#149;</B> Cost of revenues and gross margins. </I>We strive to control our cost of revenues and thereby
maintain our gross margins. Significant items impacting cost of revenues are hardware costs
paid to our contract manufacturers, third-party software license fees, amortization of
acquired technology, personnel and overhead expenses. Our margins have remained relatively
stable over the past two years; however factors such as sales price, product mix, inventory
obsolescence, returns, component price increases, and warranty costs could significantly
impact our gross margins from quarter to quarter and represent the significant indicators we
monitor on a regular basis.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%"><I><B>&#149;</B> Operating expenses. </I>Operating expenses are substantially driven by personnel and related
overhead expenses. Existing headcount and future hiring plans are the predominant factors in
analyzing and forecasting future operating expense trends. Other significant operating
expenses that we monitor include marketing and promotions, travel, professional fees,
computer costs related to the development of new products, facilities and depreciation
expenses.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%"><I><B>&#149;</B> Liquidity and cash flows. </I>Our financial condition remains strong with significant cash and
investments and no long term debt. The increase in cash and investments during the first
nine months of fiscal 2005 was primarily due to the proceeds from the exercise of employee
stock options and cash from operations. Going forward, we believe the primary driver of our
cash flows will be net income from operations. Capital expenditures during the first nine
months of fiscal 2005 were comprised primarily of tenant improvements

activities.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt; margin-left: 3%"><I><B>&#149;</B> Balance sheet. </I>We view cash, short-term and long-term investments, deferred revenue,
accounts receivable balances and day&#146;s sales outstanding as important indicators of our
financial health. Deferred revenues continued to increase due to the growth in the amount of
annual maintenance contracts purchased on new products and maintenance renewal contracts
related to our existing product installation base. Our day&#146;s sales outstanding for the third
quarter of fiscal 2005 was 46. We expect to maintain this metric in the mid-to-high 40&#146;s
range going forward.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Critical Accounting Policies and Estimates</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our consolidated financial statements have been prepared in accordance with accounting
principles generally accepted in the United States of America. The preparation of these financial
statements requires us to make estimates and judgments that affect the reported amounts of assets,
liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We
base our estimates on historical experience and on various other assumptions that are believed to
be reasonable under the circumstances. Actual results may differ from these estimates under
different assumptions or conditions.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We believe the following critical accounting policies affect the more significant judgments
and estimates used in the preparation of our financial statements. These critical accounting
policies are consistent with those disclosed in our Annual Report on Form 10-K.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Revenue Recognition. </I>We recognize revenue in accordance with the guidance provided under
Statement of Position (SOP)&nbsp;No.&nbsp;97-2, &#147;Software Revenue Recognition,&#148; and SOP No.&nbsp;98-9
&#147;Modification of SOP No.&nbsp;97-2, Software Revenue Recognition, with Respect to Certain Transactions.&#148;
Statement of Financial Accounting Standards (SFAS)&nbsp;No.&nbsp;48, &#147;Revenue Recognition When Right of
Return Exists,&#148; and SEC Staff Accounting Bulletin (SAB)&nbsp;No.&nbsp;104, &#147;Revenue Recognition.&#148;
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We sell products through distributors, resellers, and directly to end users. We recognize
product revenue upon shipment, net of estimated returns, provided that collection is determined to
be probable and no significant obligations remain. In certain regions where we do not have the
ability to reasonably estimate returns, we defer revenue on sales to distributors until we have
received information from the channel partner indicating that the distributor has sold the product
to its customer. Payment terms to domestic customers are generally net 30&nbsp;days. Payment terms to
international customers range from net 30 to 90&nbsp;days based on normal and customary trade practices
in the individual markets. We have offered extended payment terms to certain customers, in which
case, revenue is recognized when payments are made.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Whenever a software license, hardware, installation and post-contract customer support, or
PCS, elements are sold together, a portion of the sales price is allocated to each element based on
their respective fair values as determined when the individual elements are sold separately.
Revenues from the license of software are recognized when the software has been shipped and the
customer is obligated to pay for the software. When rights of return are present and we cannot
estimate returns, we recognize revenue when such rights of return lapse. Revenues for PCS are
recognized on a straight-line basis over the service contract term. PCS includes rights to
upgrades, when and if available, a limited period of telephone support, updates, and bug fixes.
Installation revenue is recognized when the product has been installed at the customer&#146;s site.
Consulting services are customarily billed at fixed rates, plus out-of-pocket expenses, and
revenues are recognized when the consulting has been completed. Training revenue is recognized when
the training has been completed.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Reserve for Doubtful Accounts. </I>Estimates are used in determining our allowance for doubtful
accounts and are based upon an assessment of selected accounts and as a percentage of our remaining
accounts receivable by aging category. In determining these percentages, we evaluate historical
write-offs, current trends in the credit quality of our customer base, and changes in our credit
policies. We perform ongoing credit evaluations of our customers&#146; financial condition and generally
do not require any collateral. If there is deterioration of a major customer&#146;s credit

actual defaults are higher than our historical experience, our allowance for doubtful accounts may
not be sufficient.
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Reserve for Product Returns. </I>In some instances, product revenue from distributors is subject
to agreements allowing rights of return. Product returns are estimated based on historical
experience and are recorded at the time revenues are recognized. Accordingly, we reduce recognized
revenue for estimated future returns at the time revenue is recorded. When rights of return are
present and we cannot estimate returns, revenue is recognized when such rights lapse. The estimates
for returns are adjusted periodically based upon changes in historical rates of returns, inventory
in the distribution channel and other related factors. It is possible that these estimates will
change in the future or that the actual amounts could vary from our estimates.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Reserve for Warranties. </I>A warranty reserve is established based on our historical experience
and an estimate of the amounts necessary to settle future and existing claims on products sold as
of the balance sheet date. While we believe that our warranty reserve is adequate and that the
judgment applied is appropriate, such amounts estimated to be due and payable could differ
materially from what will actually transpire in the future.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Accounting for Income Taxes. </I>We utilize the liability method of accounting for income taxes
pursuant to SFAS 109. Accordingly, we are required to estimate our income taxes in each of the
jurisdictions in which we operate as part of the process of preparing our consolidated financial
statements. This process involves estimating our actual current tax exposure, including assessing
the risks associated with tax audits, together with assessing temporary differences resulting from
the different treatment of items for tax and accounting purposes. These differences result in
deferred tax assets and liabilities. Due to the evolving nature of tax rules combined with the
large number of jurisdictions in which we operate, it is possible that our estimates of our tax
liability could change in the future, which may result in additional tax liabilities and adversely
affect our results of operations, financial condition and cash flows.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Net revenues. </I>Total net revenues increased approximately 65% for the three and nine
months ended June&nbsp;30, 2005, from comparable periods in the prior year. The improvements were due
to increased demand of our core traffic management products, particularly our recently introduced
Version 9 BIG-IP products. Revenues from our new security products, predominantly our FirePass
SSL/VPN products, contributed to the overall increase and represented 10.4% and 9.5% of total
revenues for the three and nine months ended June&nbsp;30, 2005, respectively. Higher services revenues
resulting from our increased installed base of products contributed to the overall increases as
compared to each of the prior periods. Each of our primary geographic regions reported higher
revenues compared to the prior year period; however, the increase in revenues was primarily driven
by higher sales in the Americas. International revenues were 35.7% of total net revenues for the
three months ended June&nbsp;30, 2005 compared to 37.2% for the same period in the prior year.
International revenues increased to 40.4% of total net

2005, respectively, from the comparable periods in the prior year. Sales of our BIG-IP family of
application traffic management products represented 88.8% and 88.2% of product revenues for the
three months ended June&nbsp;30, 2005 and 2004, respectively, and 89.5% and 91.0% of product revenues

36.3% and 36.0% for the three and nine months ended June&nbsp;30, 2005, respectively, up from the
comparable periods in the prior year. The increase in services revenue was primarily due to
increases in the purchase or renewal of service and support contracts as our installed base of
products increased.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Cost of Net Product Revenues</I>. Cost of net product revenues consists of finished products
purchased from our contract manufacturers, third-party software license fees, manufacturing
overhead, freight, warranty, amortization of acquired technology, and in some cases provisions for
excess and obsolete inventory. Our product margins remained stable for all periods presented at
approximately 77%. In absolute dollars, cost of net product revenues increased 75.5% and 76.2% for
the three and nine months ended June&nbsp;30, 2005, respectively, up from the comparable periods in the
prior year. The increases were primarily due to an increase in the amount of units shipped.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Cost of Net Services Revenues</I>. Cost of net service revenues consist of the salaries and
related benefits of the majority of our professional services staff, travel, facilities, and
depreciation expenses. For the three and nine months ended June&nbsp;30, 2005, cost of net services
revenues increased as a percentage of services revenues and increased in absolute dollars as a
result of the recent growth in headcount. Services employee headcount at the end of June&nbsp;2005
increased to 121 from 87 at the end of June&nbsp;2004. We expect cost of services revenues to continue
at these higher levels to support the growth in revenues.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We expect to maintain our gross margins in the near term; however, gross margins could be
adversely affected by increased material costs, component shortages, excess and obsolete inventory
charges and heightened sales price competition.

related expenses of our sales and marketing staff, costs of our marketing programs, including
public relations, advertising and trade shows, facilities and depreciation expenses. The decrease
in sales and marketing expenses as a percentage of total net revenues is primarily the result of
leveraging our existing sales and distribution infrastructure to support the increased net
revenues. In absolute dollars, sales and marketing expenses increased 37.3% and 33.4% for the
three and nine months ended June&nbsp;30, 2005, respectively, up from the comparable periods in the
prior year. The increase in sales and marketing expenses was primarily due to higher commissions
and personnel costs of $4.3&nbsp;million and $10.8&nbsp;million for the three and nine months ended June&nbsp;30,
2005, respectively. The increased commission and personnel costs were driven by growth in employee
headcount and increased revenue for the respective periods. Sales and marketing headcount at the
end of June&nbsp;2005 increased to 309 from 244 at the end of June&nbsp;2004. In the future, we expect to

expenses increased 20.7% and 26.8% for the three and nine months ended June&nbsp;30, 2005, respectively,
up from the comparable periods in the prior year. The increase was partially due to higher
personnel costs of $0.4&nbsp;million and $2.5&nbsp;million for the three and nine months ended June&nbsp;30, 2005,
respectively. Research and development headcount at the end of June&nbsp;2005 totaled 211 up from 177
at the end of June&nbsp;2004. Higher prototype expenses of $0.7&nbsp;million and $1.4&nbsp;million for the three
and nine months ended June&nbsp;30, 2005, respectively, also contributed to the increase. We expect to
continue to increase research and development expenses as our future success is dependent on the
continued enhancement of our current products and our ability to develop new,
technologically-advanced products that meet the changing needs of our customers.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>General and administrative</I>. General and administrative expenses consist of salaries and
related expenses of our executive, finance, information technology, human resource and legal
personnel, third-party professional service fees, bad debt charges, facilities and depreciation
expenses. The decrease in general and administrative expenses as a percentage of total net
revenues is primarily the result of leveraging our existing corporate infrastructure to support the
increased net revenues. In absolute dollars, general and administrative expenses increased 43.4%
and 48.1% for the three and nine months ended June&nbsp;30, 2005, respectively, up from the comparable
periods in the prior year. The increase was primarily due to higher salary and benefit costs of
$0.7&nbsp;million and $2.3&nbsp;million and higher professional service fees of $0.5&nbsp;million and $1.5&nbsp;million
for the three and nine months ended June&nbsp;30, 2005, respectively. The increase in personnel costs
was primarily driven by growth in headcount. General and administrative headcount at the end of

compensation arrangements and expect to recognize pre-tax stock-based compensation costs of $5.2
million in the fourth quarter of fiscal 2005. For fiscal 2006, we expect the pre-tax charge to be
approximately $6&nbsp;million per quarter, or $24&nbsp;million for the full year, not including incremental
costs for any additional follow-on awards which may be granted in the fourth quarter of fiscal
2006.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Other income, net. </I>Other income, net, consists of interest income and foreign currency
transaction gains and losses. The significant increase was due to a combination of higher yields
and increased investment balances.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<I>Income taxes</I>. We recorded a 36% provision for income taxes for the nine months ended June&nbsp;30,
2005. In the prior comparable periods when we had a valuation allowance offsetting our U.S.
deferred tax assets, the provision for income taxes consisted primarily of foreign taxes related to
our international operations. In the fourth quarter of fiscal 2005, we expect to record a
provision for income taxes comparable to the current period; however, our effective tax rate may
fluctuate based on a number of factors including variations in estimated taxable income in our
geographic locations, unforeseen changes in the valuation of our net deferred tax assets or changes
in tax laws or interpretations thereof.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 12pt"><B>Financial Condition</B>
</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash and cash equivalents, short-term investments and long-term investments were $329.1
million as of June&nbsp;30, 2005 compared to $222.3&nbsp;million as of September&nbsp;30, 2004. The increase was
due to cash provided by operations of $52.3&nbsp;million and cash received from employee stock option
exercises and ESPP activity of $64.6&nbsp;million.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash provided by operating activities was $52.3&nbsp;million for the nine months ended June&nbsp;30,
2005 compared to $29.2&nbsp;million for the same period in the prior year. Cash flow from operations in
the nine months ended June&nbsp;30, 2005 resulted from increased net income combined with changes in
operating assets and liabilities, as adjusted for various non-cash items including corporate tax
deductions on certain employee stock option exercises and depreciation and amortization charges.
Due to the significant amount of cumulative net operating losses for tax purposes we do not expect
to incur or remit U.S. federal income taxes for the remainder of fiscal 2005.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cash used in investing activities was $130.2&nbsp;million for the nine months ended June&nbsp;30, 2005
compared to $152.8&nbsp;million for the same period in the prior year. The significant amount of cash
used in investing activities in the prior period was primarily due to the investment of proceeds
from our public offering in November&nbsp;2003. Cash provided by financing activities for the nine
months ended June&nbsp;30, 2005 was $64.6&nbsp;million compared to $135.2&nbsp;million for the same
period in the prior year. Our financing activities in the current period consisted of cash
received from the exercise of employee stock options and purchases under our employee stock
purchase plan. Financing activities in the prior period was primarily attributed to the $113.6
million net proceeds received from the November&nbsp;2003 public stock offering. Based on our current
operating and capital expenditure forecasts, we believe that our existing cash and investment
balances together with cash generated from operations should be sufficient to meet our operating
requirements for the foreseeable future.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of June&nbsp;30, 2005, our principal commitments consisted of obligations outstanding under
operating leases. We lease our facilities under operating leases that expire at various dates
through 2012. There have been no material changes in our principal lease commitments compared to
those discussed in our Annual Report on Form 10-K for the year ended September&nbsp;30, 2004. In
connection with the lease agreement for our corporate headquarters we established a restricted
escrow account collateralized by a $6.0&nbsp;million certificate of deposit that has been included on
our balance sheet as a component of restricted cash. In July of 2005, the total amount required in
escrow will be reduced to $3.6&nbsp;million as set forth by the lease agreement.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We outsource the manufacturing of our pre-configured hardware platforms to contract
manufacturers who assemble each product to our specifications. Our agreement with our largest
contract manufacturer allows them to procure component inventory on our behalf based upon a rolling
production forecast. We are contractually obligated to purchase the component inventory in
accordance with the forecast, unless we give notice of order cancellation in advance of applicable
lead times. As of June&nbsp;30, 2005, we were committed to purchase approximately $9.9&nbsp;million of such
inventory over the next quarter.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Management believes there have been no material changes to our quantitative and qualitative
disclosures about market risk during the nine month period ended June&nbsp;30, 2005, compared to those
discussed in our Annual Report on Form 10-K for the year ended September&nbsp;30, 2004.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As of June&nbsp;30, 2005, we carried out an evaluation, under the supervision and with the
participation of the Company&#146;s management, including our Chief Executive Officer and Chief
Financial Officer, of the effectiveness of the design and operation of our disclosure controls and
procedures pursuant to Exchange Act Rule&nbsp;13a-15(e) and 15d-15(e). Based upon that evaluation, the
Chief Executive Officer and the Chief Financial Officer concluded that our disclosure controls and
procedures are effective to timely alert them to any material information relating to the Company
(including its consolidated subsidiaries) that must be included in our periodic SEC filings. There
have been no significant changes in the Company&#146;s internal controls or in other factors that could
significantly affect internal controls subsequent to their evaluation.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We intend to review and evaluate the design and effectiveness of our disclosure controls and
procedures on an ongoing basis and to improve our controls and procedures over time and to correct
any deficiencies that we may discover in the future. Our goal is to ensure that our senior
management has timely access to all material financial and non-financial information concerning our
business. While we believe the present design of our disclosure controls and procedures is
effective to achieve our goal, future events affecting our business may cause us to modify our
disclosure controls and procedures.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are in the process of implementing the requirements of Section&nbsp;404 of the Sarbanes-Oxley
Act of 2002 which requires our management to assess the effectiveness of our internal controls over
financial reporting and include an assertion in our annual report as to the effectiveness of our
controls. Subsequently, our independent registered public accounting firm, PricewaterhouseCoopers
LLP, will be required to attest to whether our assessment of the

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">effectiveness of our internal
controls over financial reporting is fairly stated in all material respects and separately report
on whether it believes we maintained, in all material respects, effective internal controls over
financial reporting as of September&nbsp;30, 2005. We are in the process of performing the system and
process documentation, evaluation and testing required for management to make this assessment and
for PricewaterhouseCoopers LLP to provide its attestation report. We have not
yet completed this process or its assessment, and this process will continue to require
significant amounts of management time and resources. In the course of evaluation and testing,
management may identify deficiencies that will need to be addressed and remediated.

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company is not aware of any pending legal proceedings that, individually or in the
aggregate, would have a material adverse effect on the Company&#146;s business, operating results, or
financial condition. The Company may in the future be party to litigation arising in the ordinary
course of business, including claims that allegedly infringe upon third-party trademarks or other
intellectual property rights. Such claims, even if not meritorious, could result in the
expenditure of significant financial and managerial resources.

ended September&nbsp;30, 2004, filed with the Securities and Exchange Commission on December&nbsp;7, 2004 for
descriptions of our legal proceedings. We continue to believe that the resolution of these legal
proceedings will not have a material adverse effect on us and other than the settlement with
Radware in March&nbsp;2005; there have been no other material developments since our 10-K filing.

</DIV>


<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;On August&nbsp;1, 2005, as part of an equity incentive plan for eligible employees and
non-employee directors, the Board of Directors of F5 Networks, Inc. were each granted 2,500
restricted stock units (&#147;RSUs&#148;) under the terms of the 2005 Equity Incentive Plan. The closing
sale price per share of our common stock on August&nbsp;1, 2005 was $42.17. Directors receiving RSU
grants were A. Gary Ames, Keith D. Grinstein, Karl D. Guelich, Alan Higginson and Rich Malone.
Subject to the director&#146;s continuing service with the Company throughout such period, the RSUs will
vest on the date of the Company&#146;s Annual Meeting of Shareholders for fiscal year end 2005 except
that in the event of a change in control of the Company, the vesting of 100% of the RSUs will
accelerate immediately prior to the change of control.
</DIV>

<DIV align="left" style="font-size: 10pt; margin-top: 6pt">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Certain of the Company&#146;s executive officers also received RSU grants under the terms of the
2005 Equity Incentive Plan. John McAdam, the Company&#146;s Chief Executive Officer and President, was
granted 50,000 RSUs. Dan Matte, the Company&#146;s Senior VP of Marketing, was granted 25,000 RSUs.
The Company&#146;s other executive officers, Julian Eames, Tom Hull, Jeff Pancottine, Joann Reiter and
Karl Triebes were each granted 20,000 RSUs. Subject to the officer&#146;s continuing service with the
Company throughout such period, the RSUs will vest in consecutive equal quarterly increments over
the two year period following the date of grant except that in the event of a change in control of
the Company, the vesting of 100% of the RSU&#146;s will accelerate immediately prior to the change of
control.

                                 AWARD AGREEMENT
                              (ACCELERATED VESTING)

      Pursuant to the terms of its 2005 Equity Incentive Plan (the "Plan"), F5
Networks, Inc., a Washington corporation (the "Company"), has granted you an
award (the "Award") (either a non-statutory stock option to purchase shares of
the Company's Common Stock (an "Option") or stock units representing the right
to receive shares of the Company's Common Stock ("Stock Units") as set forth in
the Notice of Grant of Stock Options or Stock Units (the "Grant Notice")) on the
terms and conditions as set forth in this 2005 Equity Incentive Plan Award
Agreement (this "Agreement"), the Grant Notice (which is incorporated herein by
reference) and the Plan (which is incorporated herein by reference). Capitalized
terms used but not defined in this Agreement shall have the meanings specified
in the Plan.

      IN CONSIDERATION OF THE MUTUAL PROMISES SET FORTH BELOW, THE PARTIES AGREE
AS FOLLOWS:

      1. GRANT OF AWARD; GRANT DATE. The Company has granted you an Award to
purchase (in the case of an Option) or to be issued (in the case of Stock Units)
the total number of shares of Common Stock of the Company as set forth in the
Grant Notice (the "Award Shares") on the terms and conditions set forth in this
Agreement, the Grant Notice and the Plan, including in the case of an Option at
the exercise price per share of Common Stock set forth in the Grant Notice (the
"Award Price"). The number and kind of Award Shares and the Award Price may be
adjusted in certain circumstances in accordance with Section 11 of the Plan.

      2. VESTING AND EXERCISE OR SETTLEMENT OF STOCK.

      2.1. Options.

            (a) The Option will vest and become exercisable during its term in
accordance with the vesting schedule set forth in the Grant Notice and with the
applicable provisions of the Plan and this Agreement. Vesting will cease upon
the termination of your Continuous Service except as otherwise set forth in the
Plan or this Agreement.

            (b) The vested and exercisable portion of the Option may be
exercised during its term (as set forth in Section 6) electronically as directed
by the Company or by delivering a Notice of Exercise (in a form designated by
the Company), together with the Award Price (payable in the manner set forth in
Section 3) to the Secretary of the Company, or to such other person as the
Company may designate, during regular business hours, together with such
additional documents as the Company may then require.

            (c) By exercising the Option, you agree that, as a condition to any
exercise of the Option, the Company may require you to enter an arrangement
providing for the payment by you to the Company of any tax withholding
obligation of the Company arising by reason of (1) the exercise of the Option or
(2) the disposition of shares acquired upon such exercise.

            2.2. Stock Units. On each date that Stock Units vest (a "Vesting
Date"), the Stock Units will be settled as to the number of shares vesting on
such Vesting Date, meaning that the Company will (subject to your obligations to
satisfy the requirements of Sections 5 and 9) issue to you the number of shares
vesting on such Vesting Date and the Award will thereafter remain in effect only
as to the number of unvested shares of Common Stock remaining subject thereto.
The shares of Common Stock issued upon conversion of Stock Units will be
registered in your name as of each Vesting Date on the register of shareholders
of the Company (through its transfer agent).

            2.3. Accelerated Vesting. Notwithstanding the vesting provisions set
forth in the Grant Notice and Section 11 of the Plan, in the event of a change
in control transaction as described in Section 11 of the Plan, the vesting of
100% of the shares of Common Stock subject to the Award (and if applicable, the
time during which the

<PAGE>

Award may be exercised or settled) shall be accelerated in full, and the Award
shall terminate if not exercised or settled at or prior to the closing of the
change in control transaction.

      3. METHOD OF PAYMENT OF THE OPTION AWARD PRICE. Payment of the Award Price
is due in full upon exercise of all or any part of the Option. You may elect to
make payment of the Award Price by any of the methods, or combination thereof,
described in the Plan, provided that the Board may, in its sole discretion,
refuse to accept a particular form of consideration at the time of exercise of
any Option, or agree to accept any other form of legal consideration.

      4. WHOLE SHARES. The Award may only be exercised or settled for whole
shares.

      5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, the Award may not be exercised or settled unless the shares
issuable upon exercise or settlement of the Award are then registered under the
Securities Act or, if such shares are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. The exercise or settlement of the Award must
also comply with other applicable laws and regulations governing the Award, and
the Award may not be exercised or settled, and the Company will have no
liability for failure to issue shares of Common Stock upon exercise or
settlement of the Award, if the Company determines that the exercise or
settlement would not be in material compliance with such laws and regulations.

      6. TERM AND TERMINATION OF AWARD.

            6.1. Options. Subject to earlier termination as required under
Section 11 of the Plan, the term of the Option commences on the Grant Date and
expires upon the earliest of the following:

            (a) three (3) months after the termination of your Continuous
Service for any reason other than death or Disability, provided that if during
any part of such three-month period the Option is not exercisable solely because
of the condition set forth in Section 5, the Option shall not expire until the
earlier of the Expiration Date or until it shall have been exercisable for an
aggregate period of three (3) months after the termination of your Continuous
Service;

            (b) twelve (12) months after the termination of your Continuous
Service due to Disability;

            (c) eighteen (18) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates for reason other than Cause;

            (d) the Expiration Date indicated in the Grant Notice; or

            (e) the tenth (10th) anniversary of the Grant Date.

            6.2. Stock Units. In the event your Continuous Service terminates,
any Stock Units and the shares of Common Stock subject thereto (that have not
been issued upon settlement) shall be forfeited.

      7. TRANSFERABILITY. The Award is not transferable, except by will or by
the laws of descent and distribution. Options are exercisable during your life
only by you. Shares of Common Stock issued upon vesting of a Stock Unit are
issuable during your life only to you. Notwithstanding the foregoing, by
delivering written notice to the Company, in a form satisfactory to the Company,
you may designate a third party who, in the event of your death, shall
thereafter be entitled to exercise the Option or receive shares of Common Stock
issued upon vesting of a Stock Unit.

      8. NOT A SERVICE CONTRACT. This Agreement is not an employment or service
contract, and nothing in this Agreement shall be deemed to create in any way
whatsoever any obligation on your part to continue in the employ of the Company
or an Affiliate, or of the Company or an Affiliate to continue your employment.
In addition, nothing in this Agreement shall obligate the Company or an
Affiliate, their respective shareholders, Board, officers or employees to
continue any relationship that you might have as a director or consultant for
the Company or an

<PAGE>

Affiliate.

      9. WITHHOLDING OBLIGATIONS.

            9.1. At the time the Option is exercised, in whole or in part, or
shares of Common Stock are issued upon settlement of Stock Units or at any time
thereafter as requested by the Company, you hereby authorize withholding from
payroll and any other amounts payable to you, or otherwise agree to make
adequate provision for (including by means of a "cashless exercise" pursuant to
a program developed under Regulation T as promulgated by the Federal Reserve
Board to the extent permitted by the Company), any sums required to satisfy the
federal, state, local and foreign tax withholding obligations of the Company or
an Affiliate, which arise in connection with the Award.

            9.2. The Option is not exercisable and shares of Common Stock are
not issuable upon settlement of Stock Units unless the tax withholding
obligations of the Company are satisfied. Accordingly, you may not be able to
exercise the Option or receive shares of Common Stock upon settlement of Stock
Units when desired even though the Award is vested.

      10. PROFESSIONAL ADVICE. The acceptance and exercise or settlement of the
Award and the sale of Award Shares has consequences under federal and state tax
and securities laws which may vary depending upon your individual circumstances.
Accordingly, you acknowledge that you have been advised to consult your personal
legal and tax advisor in connection with this Agreement and your dealings with
respect to the Award and the Award Shares. You further acknowledge that the
Company has made no warranties or representations to you with respect to the
income tax consequences of the grant and exercise or settlement of the Award or
the sale of the Award Shares and you are in no manner relying on the Company or
its representatives for an assessment of such consequences.

      11. GOVERNING PLAN DOCUMENT. Your Award is subject to all applicable
provisions of the Plan, which are hereby made a part of your Award, and is
further subject to all interpretations, amendments, rules and regulations which
may from time to time be promulgated and adopted pursuant to the Plan. In the
event of any conflict between the provisions of your Award and those of the
Plan, the provisions of the Plan shall control.

      12. DAMAGES. You shall be liable to the Company for all costs and damages,
including incidental and consequential damages, resulting from a disposition of
Award Shares which is not in conformity with the provisions of this Agreement.

      13. GOVERNING LAW. This Agreement shall be governed by, and construed in
accordance with, the laws of the State of Washington excluding those laws that
direct the application of the laws of another jurisdiction.

contrary, all notices, communications, and documents directed to the Company and

            to the period covered by this report;

      3)    Based on my knowledge, the financial statements, and other financial
            information included in this report, fairly present in all material

      4)    The registrant's other certifying officer and I are responsible for
            establishing and maintaining disclosure controls and procedures (as
            defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the
            registrant and have:

            a.    designed such disclosure controls and procedures, or caused
                  such disclosure controls and procedures to be designed under
                  our supervision, to ensure that material information relating
                  to the registrant, including its consolidated subsidiaries, is
                  made known to us by others within those entities, particularly

                  and procedures, as of the end of the period covered by this

            c.    disclosed in this report any change in the registrant's
                  internal controls over financial reporting that occurred
                  during our most recent fiscal quarter that has materially
                  affected, or is reasonably likely to materially affect, the
                  registrant's internal controls over financial reporting; and

      5)    The registrant's other certifying officer and I have disclosed,
            based on our most recent evaluation, to the registrant's auditors
            and the audit committee of registrant's board of directors (or
            persons performing the equivalent functions):

            a.    all significant deficiencies and material weaknesses in the
                  design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  registrant's ability to record, process, summarize and report
                  financial information; and

            b.    any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the
                  registrant's internal control over financial reporting.
