anticipates, future, intends, plans, believes, estimates, or the negative of these terms and other comparable terminology, including, but not limited to, the following:

well as assumptions. Actual results, levels of activity, performance, achievements and events could differ materially from those stated, anticipated or implied by such forward-looking statements. The factors that could contribute to such differences
include those discussed under the caption Risks And Uncertainties That You Should Consider Before Investing In Tumbleweed in section entitled Managements Discussion and Analysis of Financial Condition and Results of
Operations contained herein, as well as those discussed in our Form 10-K and other filings with the Securities and Exchange Commission. You should consider the risks factors and uncertainties under the caption Risks and Uncertainties

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES



(1) Organization



The condensed consolidated financial statements included herein have been prepared by Tumbleweed Communications Corp. (Tumbleweed) without
audit, pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and regulations. These condensed consolidated financial statements should be read in conjunction with Tumbleweeds audited financial statements and notes thereto
included in its Annual Report on Form 10-K for the fiscal year ended December 31, 2003, filed with the SEC on March 15, 2004.



The unaudited condensed consolidated financial statements included herein reflect all adjustments (which include normal, recurring adjustments) which are,
in the opinion of management, necessary to state fairly the financial position of Tumbleweed and its subsidiaries as of June 30, 2004, the results of operations for the three and six months ended June 30, 2004 and 2003, respectively, and cash flows
for the six months ended June 30, 2004 and 2003, respectively. The results for the three and six months ended June 30, 2004 and 2003, respectively, are not necessarily indicative of the results expected for the full fiscal year.



The accompanying consolidated condensed financial statements include the
accounts of Tumbleweed and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The results of operations of Tumbleweeds wholly-owned subsidiaries, Valicert, Inc.
(Valicert), Incubator, Limited (Incubator), and Corvigo, Inc. (Corvigo), have been included commencing June 23, 2003, March 15, 2004, and March 18, 2004, the effective dates of those acquisitions, respectively.



(2) Stock-Based Compensation



Tumbleweed accounts for its stock-based compensation arrangements for
employees using the intrinsic value method pursuant to Accounting Principles Board Opinion 25, Accounting for Stock Issued to Employees. As such, deferred stock-based compensation expense is recorded for fixed plan stock options when the fair
value of the underlying common stock on the date of grant exceeds the stock option exercise price or the purchase price for issuance or sales of common stock. Deferred stock-based compensation expense is being amortized on an accelerated basis over
the vesting period of the individual award consistent with the method described in Financial Accounting Standards Board (FASB) Interpretation 28.



In the three months ended June 30, 2004, Tumbleweed recorded deferred stock-based compensation of $183,000 to recognize the fair value of stock options
granted to a non-employee for professional services. The assumptions used to value the option grant were an expected life of 10.0 years, volatility of 100%, risk-free interest rate of 2.58%, and dividend yield of 0%.



In the three months ended March 31, 2004, Tumbleweed recorded deferred
stock-based compensation of $1,397,000 for the difference at the effective date of acquisition of Corvigo between the exercise price and the fair value of the common stock underlying the unvested options assumed upon the acquisition, multiplied by
the ratio representing the remaining vesting period of the options assumed. In the three and six months ended June 30, 2003, Tumbleweed recorded deferred stock-based compensation of $528,000 for the difference at the effective date of
acquisition of Valicert between the exercise price and the fair value of the common stock underlying the unvested options assumed upon the acquisition. Tumbleweed recognized stock-based compensation expense of approximately $299,000 and $15,000, in
the three months ended June 30, 2004 and 2003, respectively, and approximately $381,000 and $49,000, in the six months ended June 30, 2004 and 2003, respectively.



Had stock-based compensation expense for its stock-based compensation plan been determined consistent with the fair value
approach set forth in Statement of Financial Accounting Standards (SFAS) 123, Accounting for Stock-Based Compensation, Tumbleweeds net losses for the three and six months ended June 30, 2004 and 2003, respectively, would
have been as follows (in thousands, except per share amounts):

(4) Business Combination



On March 18, 2004, Tumbleweed completed the acquisition
of Corvigo, an anti-spam appliance vendor. The acquisition was entered into to strengthen Tumbleweeds position in the anti-spam and e-mail security markets and to accelerate Tumbleweeds distribution plans through the addition of
resellers already selling the Corvigo appliance. Since March 18, 2004, Corvigos results of operations have been included in Tumbleweeds consolidated condensed financial statements. The acquisition was accounted for using the purchase
method of accounting and accordingly, the purchase price was allocated to the assets acquired and liabilities assumed based on their estimated fair values on the acquisition date. The purchase price of $42.3 million consisted of an exchange of
4,732,284 shares of Tumbleweeds common stock with a fair value of $32.8 million based on the fair value of Tumbleweeds common stock on the date of the acquisition, cash paid of $6.0 million, an exchange of 386,000 options to purchase
Tumbleweeds common stock with a fair value of $2.7 million, including the intrinsic value of unvested options of $1.4 million, severances for former Corvigo employees of $97,000, and other acquisition-related costs of $644,000, consisting
primarily of legal fees, banking fees, and accounting fees.

Goodwill represents
the excess of the purchase price over the fair value of acquired net tangible and identified intangible assets. In accordance with the provisions of SFAS 142, Goodwill and Other Intangible Assets, the goodwill acquired in the Valicert,
Incubator, and Corvigo acquisitions will not be amortized, but instead, the goodwill balances will be tested for impairment at least annually and more frequently if certain impairment conditions exist. Any future impairment loss related to the
goodwill recorded in connection with the acquisitions of Valicert, Incubator, and Corvigo will not be deductible by Tumbleweed for federal income tax purposes. During the three months ended June 30, 2004, Tumbleweed increased its goodwill balance by
$11,000 due to actual expenditures for acquisition-related costs related to the Corvigo acquisition being higher than previously estimated. During the three months ended June 30, 2004, Tumbleweed increased its goodwill balance by $15,000 due to
actual expenditures for acquisition-related costs related to the Incubator acquisition being higher than previously estimated.



Pro Forma Results



The following pro forma summary presents Tumbleweeds consolidated results of operations for the three and six months ended June 30, 2004 and 2003,
as if the acquisitions of Valicert, Incubator, and Corvigo had been consummated at the beginning of the earliest period. The pro forma consolidated results of operations include certain pro forma adjustments, including amortization of intangible
assets, amortization of deferred compensation and the elimination of certain merger-related charges incurred by Valicert, prior to the merger with Tumbleweed, in the three months ended March 31, 2003. The pro forma results do not give effect to the
deferred revenue adjustments on revenue as the adjustments are directly related to the mergers and the effects are non-recurring. Under the purchase method of accounting, the deferred revenue balances of Valicert, Incubator, and Corvigo were reduced
by $1.0 million, $390,000, and $793,000, respectively, to the fair value of the related obligations as of the acquisition dates of June 23, 2003; March 15, 2004; and March 18, 2004, respectively. These adjustments have had the effect of reducing the
amount of revenue the combined company recognized in the three and six months ended June 30, 2004 and will also affect the amount of revenue the combined company will recognize in future periods compared to the amount of revenue Valicert, Incubator,
and Corvigo would have recognized in the same periods absent the mergers.



Pro forma results for the three and six months ended June 30, 2004 and 2003, respectively, are as follows (in thousands, except per share amounts):

The pro forma results
are not necessarily indicative of those that would have actually occurred had the acquisition taken place at the beginning of the periods presented. Pro forma results include merger-related and other costs of $469,000 for the three and six months
ended June 30, 2004, and $1.9 million for the three and six months ended June 30, 2003, respectively.



Merger-related and other costs



Merger-related and other costs of $469,000 for the three and six months ended June 30, 2004 consist of $376,000 of severance costs for Tumbleweed
employees terminated in connection with the Corvigo and Incubator acquisitions and the sale of Tumbleweeds Indian subsidiary to a third party on June 2, 2004, $26,000 for a loss on the sale of Tumbleweeds Indian subsidiary, and $67,000
of other merger-related costs. Tumbleweeds Indian subsidiary was acquired in the acquisition of Valicert and had served as an offshore development center supporting Tumbleweeds engineering, customer support, and consulting functions. The
Indian subsidiary was sold to consolidate Tumbleweeds offshore development in its existing Bulgaria location.



During the last three quarters of 2003, Tumbleweed recorded merger-related and other costs of $2.9 million consisting of $1.1 million of severance costs
for Tumbleweed employees terminated in connection with the Valicert acquisition, $596,000 of merger-

related marketing programs, $174,000 of other merger-related costs, and a $996,000 charge related to anticipated
losses on an operating lease. The operating lease was assumed during the acquisition of Interface, Inc. in 2000 and covers approximately 13,000 square feet of office space in Slough, United Kingdom. The lease is for a term ending in 2020 with
quarterly rent payments of approximately $65,000. This office space had been subleased to a tenant who was providing Tumbleweed with quarterly rent payments of approximately $65,000 until the sublease was terminated effective July 2003. Anticipated
future sublease rental income is not expected to cover the rent expense due to a weak office rental market in and around Slough. The following table describes merger-related and other costs recorded in 2004 and 2003 (in thousands):

Accrued merger-related
and other costs at June 30, 2004 also includes liabilities of $3,000 for severance costs for former Corvigo employees and $313,000 for other merger-related costs arising from the Incubator and Corvigo acquisitions consisting primarily of legal fees,
banking fees, and accounting fees. The severance costs for former Corvigo employees and other merger-related costs arising from the Incubator and Corvigo acquisitions were recorded as goodwill in the purchase price allocations for those
acquisitions. Severance costs will be paid in 2004 and 2005. Payments for other merger-related costs will be paid in 2004. Payments for anticipated remaining losses on the operating lease are expected to occur over the life of the lease, which ends
in 2020.



Tumbleweed expects to continue to incur
merger-related and other costs in the third quarter of 2004 primarily related to severance costs for employee terminations in July 2004.



(5) Acquired Workforce



In September 2003, Tumbleweed issued 86,538 shares of stock to a company to recruit certain of its contract engineers to Tumbleweed as employees in
Tumbleweeds research and development center in Bulgaria. Tumbleweed recorded an acquired workforce intangible asset of $476,000 to recognize the fair value of the stock issued. Tumbleweed is amortizing this intangible asset over its estimated
useful life of one year. During the three and six months ended June 30, 2004, Tumbleweed recognized amortization expense of approximately $119,000 and $238,000, respectively, relating to the acquired workforce intangible asset.



(6) Comprehensive Loss



Comprehensive loss includes Tumbleweeds net loss as well as foreign currency translation adjustments, recorded net of
tax. Comprehensive loss for the three months and six months ending June 30, 2004 and 2003, respectively, is as follows (in thousands):

Contingencies



In December 2001, certain plaintiffs filed
a class action lawsuit in the United States District Court for the Southern District of New York on behalf of purchasers of the common stock of Valicert, alleging violations of federal securities laws. In re Valicert, Inc. Initial Public Offering
Securities Litigation, No. 01-CV-10889 (SAS) (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (SAS). The operative amended complaint is brought on purported behalf of all persons who purchased
Valicert common stock from the date of its July 27, 2000 initial public offering through December 6, 2000. It names as defendants Valicert, its former chief executive officer, its chief financial officer (the Valicert Defendants), as
well as an investment banking firm that served as an underwriter for the IPO. The complaint alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, on the grounds
that the registration statement for the IPO did not disclose that: (1) the underwriter agreed to allow certain customers to purchase shares in the IPO in exchange for excess commissions to the paid to the underwriter; and (2) the underwriter
arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The complaint also appears to allege that false or misleading analyst reports were issued. The complaint does not claim any specific amount of
damages. Similar allegations have been made in lawsuits relating to more than 300 other initial public offerings conducted in 1999 and 2000, all of which have been consolidated for pretrial purposes. In February 2003, the Court issued a ruling on
all defendants motions to dismiss, denying Valicerts motion to dismiss the claims under the Securities Act of 1933, but granting Valicerts motion to dismiss the claims under the Securities Exchange Act of 1934.



In June 2003, Valicert accepted a settlement proposal presented to all issuer
defendants in this case. Under the proposed settlement, the plaintiffs will dismiss and release all claims against the Valicert Defendants in exchange for a contingent payment guaranty by the insurance companies collectively responsible for insuring
the issuers in all the consolidated cases, and the assignment or surrender of control to the plaintiffs of certain claims the issuer defendants may have against the underwriters. Under the guaranty, the insurers will be required to pay the amount,
if any, by which $1 billion exceeds the aggregate amount ultimately collected by the plaintiffs from the underwriter defendants in all of the cases. If the plaintiffs fail to recover $1 billion and payment is required under the guaranty, Valicert
would be responsible to pay its pro rata portion of the shortfall, up to the amount of the deductible retention under its insurance policy, which is $500,000. The timing and amount of payments that Valicert could be required to make under the
proposed settlement will depend on several factors, principally the timing and amount of any payment required by the insurers pursuant to the $1 billion guaranty. The proposed settlement is subject to approval of the Court, which cannot be assured.
The accompanying condensed consolidated financial statements do not include a reserve for any potential loss, as Tumbleweed does not consider a loss to be probable at this time.



In June 2003, Tumbleweed was served with a summons and first amended complaint, captioned Liu v. Credit Suisse First
Boston, et alia, alleging the violation of federal and state securities laws, purportedly on behalf of persons who acquired the common stock of Tumbleweed (other than purchasers of Tumbleweeds initial public offering) from August 6, 1999
to October 18, 2000. The case is now pending in the United States District Court for the Southern District of New York. In May 2004, the Court granted plaintiffs motion for leave to file a second amended complaint. Tumbleweed and the other
defendants intend to file motions to dismiss this case pursuant to Fed. R. Civ. P. 12(b). An adverse outcome in this case could harm Tumbleweeds business and operating results. Moreover, the costs in defending this lawsuit could harm future
operating results. The accompanying condensed consolidated financial statements do not include a reserve for any potential loss, as Tumbleweed does not consider a loss to be probable at this time.



All costs incurred as a result of these legal proceedings and claims are
charged to expense as incurred.



Tumbleweed indemnifies its
customers from third party claims of intellectual property infringement relating to the use of its products. Historically, costs related to these guarantees have not been significant and Tumbleweed is unable to estimate the potential impact of these
guarantees on its future results of operations.

(9) Recent Accounting Pronouncements



In November 2002, the Emerging Issues Task Force (EITF) reached a consensus on Issue 00-21 (EITF
00-21), Revenue Arrangements with Multiple Deliverables. EITF 00-21 addresses certain aspects of the accounting by a vendor for arrangements under which the vendor will perform multiple revenue-generating activities. Tumbleweed adopted
the provisions of EITF 00-21 as of July 1, 2003. The adoption of EITF 00-21 did not have a material impact on its financial position or results of operations.



In March 2004, the EITF reached consensus on Issue 03-01 (EITF 03-01), The Meaning of Other-Than-Temporary Impairment and Its
Application to Certain Investments. EITF 03-01 includes new guidance for evaluating and recording impairment losses on debt and equity investments, as well as new disclosure requirements for investments that are deemed to be temporarily
impaired. The accounting guidance of EITF 03-01 is effective for reporting periods beginning after June 15, 2004, while the disclosure requirements for debt and equity securities accounted for under SFAS 115, Accounting for Certain
Investments in Debt and Equity Securities, are effective for annual periods ending after December 15, 2003. Tumbleweed does not believe that the adoption of EITF 03-01 will have a material impact on its financial position or results of
operations.



ITEM 2MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS



The following discussion should be read in conjunction with the consolidated condensed financial statements and the accompanying notes to this

Overview of the Three and Six Month Periods Ended June 30, 2004



Our operating results during the three and six months ended June 30, 2004 showed improvement relative to the same three and
six months in 2003 in revenue and net loss. Our growth in revenue of 63% and 69% in the three and six month periods ended June 30, 2004, respectively, from the same three and six months in 2003, was driven by a number of factors including increased
customer adoption of our email firewall products, revenues from the secure file transfer and identity validation products we acquired in the Valicert acquisition, revenue from the MailGate product acquired in the Corvigo acquisition, and growth in
our targeted customer

sectors in the financial services, health care, and government industries. Our reduction in net loss of 21% and 43%
in the three and six month periods ended June 30, 2004, respectively, from the same three and six months in 2003, was due to our growth in revenues and our continuing focus on generating cost efficiencies including our development center in Bulgaria
which has allowed us to augment our research and development and services offerings at a relatively lower cost structure. In addition, operating cash flow improved by 96% in the six months ended June 30, 2004 due to our reduction in net loss and
lower accounts receivable balance due to an increase in collections from our customers.



Key Performance Indicators



Our key
performance indicators are customer orders received (bookings), recognized revenue and deferred revenue. We measure bookings as the dollar value of contractual agreements entered into with customers in the period that result in either revenue
recognized in the period, deferred revenue at the end of the period, or expected billings in future periods. Generally, an increase in our bookings will result in an increase in our revenues. The timing of bookings is uncertain as we sell to
enterprises and government entities and the process of contractual negotiation is critical and may be lengthy. Many enterprise customers negotiate software licenses near the end of each quarter.



Outlook



We believe that our success in 2004 will depend particularly on our ability to increase customer adoption of our email
firewall, secure file transfer, anti-spam appliance, and identity validation products, our ability to successfully integrate the Valicert, Incubator, and Corvigo acquisitions, and our ability to maintain control over expenses and cash. We believe
that key risks include overall economic conditions and the overall level of information technology spending; economic and business conditions within our target customer sectors in the financial services, health care, and government industries;
timing of the closure of customer contracts; growing our sales internationally; expanding our reseller channel; and competitive factors in our rapidly changing industry. Our prospects must be considered in light of the risks, expenses and
difficulties encountered by companies at an early stage of development, particularly given that we operate in new and rapidly evolving markets, have completed several acquisitions and face an uncertain economic environment. We may not be successful
in addressing such risks and difficulties. Please refer to the Risks and Uncertainties section for additional information.



Other Recent Events



On March 18, 2004, we completed the acquisition of Corvigo. The purchase price of $42.3 million consisted of an exchange of 4,732,284 shares of our common
stock with a fair value of $32.8 million based on the fair value of our common stock on the date of the acquisition, cash paid of $6.0 million, an exchange of 386,000 options to purchase our common stock with a fair value of $2.7 million, including
the intrinsic value of unvested options of $1.4 million, severances for former Corvigo employees of $97,000, and other acquisition-related costs of $644,000, consisting primarily of legal fees, banking fees, and accounting fees.



On March 15, 2004, we completed the acquisition of Incubator. The purchase
price of $1.7 million consisted of an exchange of 224,278 shares of our common stock with a fair value of $1.6 million and other acquisition-related costs of $119,000 consisting of payments for legal fees. Additionally, Incubator may be entitled to
receive additional shares of Tumbleweed stock in the first quarters of 2005 and 2006 provided that certain sales goals are achieved.



On June 23, 2003, we completed the acquisition of Valicert. The purchase price of $17.0 million consisted of an exchange of 9,713,634 shares of our common
stock with a fair value of $13.0 million, assumed stock options with a fair value of $1.7 million, severances for former Valicert employees of $276,000, and other acquisition-related costs of $2.0 million consisting primarily of payments for legal
fees, investment banking fees, financial printing fees, accounting fees, and proxy mailing fees.



CRITICAL ACCOUNTING POLICIES AND ESTIMATES



Our discussion and analysis of our financial condition and results of operations are based upon our consolidated financial statements, which have been prepared in accordance with accounting principles generally
accepted in the United States. The preparation of these financial statements requires us to make estimates and judgments in determining the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets
and liabilities. We regularly evaluate our estimates, including those related to revenue recognition, customer arrangements, collectibility of accounts receivable, valuation of assets, and contingencies and litigation. When making estimates, we
consider our historical experience, our knowledge of economic and market factors and various other assumptions that we believe to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or
conditions.



We believe that the following critical accounting
policies represent areas where significant judgments and estimates have been used in the preparation of our consolidated financial statements.

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES



Revenue Recognition



We derive our revenue from three sources: (i) product revenue, which includes license fees, subscription-based license fees, and transaction-based
license fees; (ii) service revenue, which includes support and maintenance fees, consulting fees, and training fees; and (iii) intellectual property and other revenue which includes patent license agreement fees and the sale of distribution rights.
As described below, significant management judgments and estimates must be made and used in connection with the revenue recognized in any accounting period. Material differences may result in the amount and timing of our revenue for any period based
on the judgments and estimates made by our management.



We
recognize revenue in accordance with Statement of Position (SOP) 97-2, Software Revenue Recognition (SOP 97-2), as amended by SOP 98-9, Modification of SOP 97-2, Software Revenue Recognition With
Respect to Certain Transactions(SOP 98-9).



We
make significant judgments related to revenue recognition. Specifically, in connection with each transaction involving our products, we must evaluate whether: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred, (iii) our
fee is fixed or determinable, and (iv) collectibility is probable. We apply these criteria as discussed below.



| | Persuasive evidence of an arrangement exists. We require a written contract, signed by both the customer and us, or a purchase order from those customers that have previously
negotiated a standard end-user license arrangement or volume purchase agreement with us prior to recognizing revenue on an arrangement.
|- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | Delivery has occurred. We deliver software to our customers physically or electronically. For physical deliveries, our standard transfer terms are typically FOB shipping
point. For electronic deliveries, delivery occurs when we provide the customer access codes or keys that allow the customer to take immediate possession of the software on its hardware.
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | The fee is fixed or determinable. Our determination that an arrangement fee is fixed or determinable depends principally on the arrangements payment terms. Our standard
payment terms require the arrangement fee to be paid within 90 days. Where these terms apply, we regard the fee as fixed or determinable, and we recognize revenue upon delivery (assuming other revenue recognition criteria are met). If the payment
terms do not meet this standard, which we refer to as extended payment terms, we do not consider the fee to be fixed or determinable and generally recognize revenue when customer installments are due and payable.
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | Collectibility is probable. To recognize revenue, we must judge collectibility of the arrangement fees, which we do on a customer-by-customer basis pursuant to our credit
review policy. We typically sell to customers with whom we have a history of successful collection. For new customers, we evaluate the customers financial position and ability to pay. If we determine at any time that collectibility is not
probable based upon our credit review process or the customers payment history, we recognize revenue when cash is collected.
|- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



We allocate revenue on software transactions (referred to as an arrangement in the accounting literature) involving multiple elements to each
undelivered element based on their respective fair values. The residual is allocated to the product license. Our determination of fair value of each element in multiple element arrangements is based on vendor-specific objective evidence (VSOE). We
limit our assessment of VSOE for each element to the price charged when the same element is sold separately.



Valuation of Allowance for Doubtful Accounts



We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. A considerable amount of judgment is required when we assess the realization
of receivables, including assessing the probability of collection and the current credit-worthiness of each customer. We must make estimates of the collectibility of our accounts receivables. We specifically analyze accounts receivable, including
review of historical bad debts, customer concentrations, customer credit-worthiness, current economic trends, aging of the balance and estimated collectibility percentages for different aging ranges, geographic and industry mix, and changes in our
customer payment terms when evaluating the adequacy of the allowance for doubtful accounts. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be
required which would result in an additional general and administrative expense in the period such determination is made.



Valuation of Long-Lived Assets and Goodwill



We assess the impairment of identifiable intangibles, long-lived assets and goodwill whenever events or changes in circumstances indicate that the
carrying value may not be recoverable. Factors we consider important, which could trigger an impairment review, include the following:



| | significant underperformance relative to expected historical or projected future operating results;
|- | ---------------------------------------------------------------------------------------------------



| | significant changes in the manner or our use of the acquired assets or the strategy for our overall business;
|- | -------------------------------------------------------------------------------------------------------------



| | significant negative industry or economic trends;
|- | -------------------------------------------------

| |  | significant decline in our stock price for a sustained period; and
| | - | ------------------------------------------------------------------



| |  | our market capitalization relative to net book value.
| | - | -----------------------------------------------------



We evaluate goodwill on an annual basis for indications of impairment based on our fair value as determined by our market capitalization in accordance
with SFAS 142, Goodwill and Other Intangible Assets.If this evaluation indicates that the value of the goodwill may be impaired, we make an assessment of the impairment of the goodwill using the two-step method prescribed by SFAS 142. Any
such impairment charge could be significant and have a material adverse effect on our reported financial statements. We did not record any impairment charges on our goodwill during the three and six months ended June 30, 2004 or 2003, respectively.
As of June 30, 2004, we had goodwill of $49.4 million.



Accrual for
Anticipated Operating Lease Losses



In the second quarter
of 2003 we recognized a charge of $996,000 related to potential losses on an operating lease in Slough, United Kingdom that was included in our consolidated statement of operations as Merger-related and other costs. The charge was estimated to
include required dilapidations, remaining lease liabilities, and brokerage fees, offset by estimated sublease income. Estimates related to sublease costs and income are based on assumptions regarding the period required to locate and contract with a
sublessee and sublease rates. Each reporting period we review these estimates, and to the extent that our assumptions change, the ultimate charge for the loss on this operating lease could vary from our current estimates.

RESULTS OF OPERATIONS



Three and Six Month Periods Ended June 30, 2004 and 2003



Revenue. Revenue, which consists of product revenue, service revenue and intellectual property and other revenue, results from new
contracts and backlog. We define backlog as deferred revenue, contractual commitments that are not due and payable as of the balance sheet date, or for which collectibility is in doubt, and/or for which the product or service has not yet been
delivered. Product revenue consists of license fees, subscription-based license fees, and transaction-based license fees. Service revenue includes support and maintenance fees, consulting fees, and training fees. Intellectual property and other
revenue consists of patent license agreement fees and the sale of distribution rights. Total revenue for the three months ended June 30, 2004 increased to $10.0 million from $6.1 million for the same three months in 2003. The increase in total
revenue was primarily due to a $2.6 million increase in support and maintenance revenue and a $1.3 million increase in license revenue. Total revenue for the six months ended June 30, 2004 increased to $20.2 million from $11.9 million for the same
six months in 2003. The increase in total revenue was primarily due to a $4.8 million increase in support and maintenance revenue, a $2.7 million increase in license revenue, and a $682,000 increase in patent license agreement revenue.



Product revenue increased to $4.5 million for the three months ended June
30, 2004 from $3.3 million for the same three months in 2003. Product revenue increased to $8.5 million for the six months ended June 30, 2004 from $5.9 million for the same six months in 2003. The increases in product revenue were primarily due to
increases in license revenue of $1.3 million and $2.7 million, respectively, for the three and six months ended June 30, 2004 partially offset by decreases in transaction-based license revenue of $132,000 and $121,000, respectively, for the three
and six months ended June 30, 2004. The increases in license revenue for the three and six month periods were driven by increased sales of our email firewall products and sales of the secure file transfer and MailGate products that we acquired in
the Valicert and Corvigo acquisitions, respectively, with little comparable revenue in 2003 since the Valicert acquisition occurred late in the second quarter of 2003 and the Corvigo acquisition occurred in 2004. The decreases in transaction-based
license revenue were due to our continued transition away from that selling model and toward selling perpetual licenses with associated support and maintenance contracts.



Service revenue increased to $5.1 million for the three months ended June 30, 2004 from $2.6 million for the same three
months in 2003. Service revenue increased to $10.7 million for the six months ended June 30, 2004 from $5.5 million for the same six months in 2003. The increases in service revenue were primarily due to increases in support and maintenance revenue
of $2.6 million and $4.8 million, respectively, for the three and six months ended June 30, 2004. The increases in support and maintenance revenue were due to revenue growth in our installed customer base, an expansion of our customer base due to
the Valicert acquisition, and the successful customer acceptance of our dynamic anti-spam service which was released during the three months ended June 30, 2003 and is sold on a subscription service fee basis.



Intellectual property and other revenue increased to $362,000 for the three
months ended June 30, 2004 from $250,000 for the same three months in 2003. Intellectual property and other revenue increased to $932,000 for the six months ended June 30, 2004 from $531,000 for the same six months in 2003. The increases in
intellectual property and other revenue were due to increases in patent license agreement revenue of $112,000 and $682,000, respectively, for the three and six months ended June 30, 2004. The increase in patent license agreement revenue for the six
months ended June 30, 2004 was partially offset by revenue from the sale of distribution rights recognized during the three months ended March 31, 2003 of $281,000 with no comparable revenue in 2004.



Cost of Revenue. Cost of revenue is comprised of product costs and service costs and
the amortization of core/developed technology, maintenance agreements, and purchase orders (license) relating to the Valicert, Incubator, and Corvigo acquisitions. Product costs are primarily comprised of royalties paid to third parties for software
licensed by us for inclusion in our products and the cost of hardware included in our appliance products. Service costs are comprised primarily of employee and employee-related costs for customer support and consulting and contract development
projects with third parties. Total cost of revenue increased to $1.9 million for the three months ended June 30, 2004 from $1.5 million for the same three months in 2003. The increase in total cost of revenue was due to a $193,000 increase in the
amortization of intangible assets, a $120,000 increase in product costs and a $77,000 increase in service costs. Total cost of revenue increased to $3.5 million for the six months ended June 30, 2004 from $3.0 million for the same six months in
2003. The increase in total cost of revenue was due to a $500,000 increase in the amortization of intangible assets.



Product costs increased to $381,000 for the three months ended June 30, 2004 from $261,000 for the same three months in 2003. Product costs increased to
$625,000 for the six months ended June 30, 2004 from $493,000 for the same six months in 2003. The increases in product costs were primarily due to an increase in costs of hardware included in our appliance products due to an increase in the sales
of appliance products in 2004 driven by sales of the MailGate product acquired in the Corvigo acquisition. We expect product costs to increase on a year-over-year basis in the future due to the inclusion of the costs of hardware included in sales of
our appliance products.

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES



Service costs increased to $1.0 million for the three months ended June 30, 2004 from $968,000 for
the same six months in 2003. The increase in service costs for the three month period was primarily due to the inclusion of service costs in Europe in 2004 as a result of the acquisition of Incubator in March 2004 with no comparable costs in 2003.
Service costs decreased to $2.0 for the six months ended June 30, 2004 from $2.1 million for the same six months in 2003. The decrease in service costs for the six month period were primarily due to a $68,000 decrease in employee-related costs
primarily driven by consulting personnel headcount reductions in 2003 as a result of our reduced revenue emphasis on consulting engagements.



Amortization of intangible assets included in cost of revenue consists of the amortization of intangible assets for core/developed technology, maintenance
agreements, and purchase orders (license) recorded as a result of the Valicert, Incubator, and Corvigo acquisitions. Amortization of intangible assets included in cost of revenue increased to $510,000 in the three months ended June 30, 2004 from
$317,000 for the same three months in 2003. Amortization of intangible assets included in cost of revenue increased to $817,000 in the six months ended June 30, 2004 from $317,000 for the same six months in 2003. The increases in the amortization of
intangible assets included in cost of revenue was due to the acquisitions of Corvigo and Incubator in March of 2004 and the acquisition of Valicert in June of 2003 since there was no related amortization for the Corvigo and Incubator intangible
assets in the six months ended June 30, 2003 and no related amortization for the Valicert intangible assets in the first quarter of 2003. We expect amortization of intangible assets included in cost of revenue to increase on a year-over-year basis
in the second half of 2004 as a result of the acquisitions of Corvigo and Incubator in March of 2004.



Research and Development Expenses. Research and development expenses are primarily comprised of employee and employee-related costs and other costs required for the development and quality assurance of our
products. Research and development expenses for the three months ended June 30, 2004 increased to $3.1 million from $2.1 million for the same three months in 2003. Research and development expenses for the six months ended June 30, 2004 increased to
$6.0 million from $4.0 million for the same six months in 2003. The increases in research and development expenses were primarily due to increases in employee and employee-related costs. Employee and employee-related costs increased by $894,000 and
$1.7 million, respectively, in the three and six months ended June 30, 2004 due to an increase in engineering headcount to 125 employees at June 30, 2004 from 79 employees at June 30, 2003 driven by our efforts to broaden and upgrade our products
including the addition of employees from the Valicert and Corvigo acquisitions.



Sales and Marketing Expenses. Sales and marketing expenses are primarily comprised of employee and employee-related costs, including commissions, travel expenses, and costs associated with marketing programs. Sales and marketing
expenses for the three months ended June 30, 2004 increased to $6.2 million from $3.3 million for the same three months in 2003. Sales and marketing expenses for the six months ended June 30, 2004 increased to $10.9 million from $6.7 million for the
same six months in 2003. The increases in sales and marketing expenses were primarily due to increases in employee and employee-related costs, including commissions, and marketing programs. Employee and employee-related costs, including commissions,
increased by $2.2 million and $3.5 million, respectively, in the three and six months ended June 30, 2004 due to an increase in commissions due to higher bookings and an increase in sales and marketing headcount to 83 employees at June 30, 2004 from
64 employees at June 30, 2003 due to our efforts to increase our marketing resources and expand our sales presence, and also reflects the acquisitions of Valicert, Incubator, and Corvigo. Marketing programs increased by $280,000 and $456,000,
respectively, in the three and six months ended June 30, 2004 due to an increase in marketing initiatives targeted at growing our revenues.



General and Administrative Expenses. General and administrative expenses consist primarily of employee and employee-related and support costs for our
administrative, finance, legal, and human resources departments as well as public reporting costs, bad debt expense, and professional fees including intellectual property enforcement and protection costs. General and administrative expenses for the
three months ended June 30, 2004 decreased to $1.0 million from $1.5 million for the same three months in 2003. General and administrative expenses for the six months ended June 30, 2004 decreased to $2.3 million from $2.9 million for the same six
months in 2003. The decreases in general and administrative expenses were primarily due to decreases in office expenses and legal expenses. Office expenses decreased by $102,000 and $372,000, respectively, in the three and six months ended June 30,
2004 primarily due to the renewal of our headquarters lease in third quarter of 2003 where we received a lower monthly rent cost in exchange for an extension of the lease term. Legal expenses decreased by $310,000 and $369,000, respectively, in the
three and six months ended June 30, 2004 primarily due to costs associated with the eBay patent matter in the three and six months ended June 30, 2003. The settlement of our lawsuit and signing of a cross-license agreement with eBay in the fourth
quarter of 2003 reduced costs associated with this matter in the three and six months ended June 30, 2004.



Stock-based Compensation Expense. Stock-based compensation expense consists of the amortization of deferred stock-based compensation recorded as a result of stock option grants to non-employees, unvested
options assumed in the Valicert and Corvigo acquisitions, options granted to employees at exercise prices less than the fair value of the underlying stock on the grant date, and the vesting acceleration of certain employees stock options, net
of credits related to stock options granted to employees who were later terminated before the options vested. Stock-based compensation expense for the three months ended June 30, 2004 increased to $299,000 from $15,000 for the same three months in
2003. Stock-based compensation expense for the six months ended June 30, 2004 increased to $381,000 from $49,000 for the same six months in 2003. The increases in stock-based compensation expense were due to the amortization of deferred stock-based
compensation resulting from unvested options assumed in the Valicert and Corvigo

acquisitions and a grant of stock options to a non-employee in the three and six months ended June 30, 2004 with no
comparable expense from the Corvigo acquisition and non-employee grant in 2003 and no comparable expense from the Valicert acquisition in the first quarter of 2003. We expect stock-based compensation expense to increase on a year-over-year basis in
the second half of 2004 as a result of the amortization of deferred compensation recognized as a result of Corvigo acquisition as well as the grant of options to a non-employee.



Amortization of intangible assets and write-off of in-process research and development. Amortization of intangible assets included in
operating expenses consists of the amortization of intangible assets for customer base and reseller agreements and trademarks and tradenames recorded as a result of the Valicert, Incubator, and Corvigo acquisitions. Amortization of intangible assets
included in operating expenses for the three months ended June 30, 2004 increased to $440,000 from $20,000 for the same three months in 2003. Amortization of intangible assets included in operating expenses for the six months ended June 30, 2004
increased to $716,000 from $20,000 for the same six months in 2003. The increases in the amortization of intangible assets included in operating expenses was due to the acquisitions of Corvigo and Incubator in March 2004 and the acquisition of
Valicert in June of 2003 since there was no related amortization for the Corvigo and Incubator intangible assets in the six months ended June 30, 2003 and no related amortization for the Valicert intangible assets in the first quarter of 2003. We
expect amortization of intangible assets included in operating expenses to increase on a year-over-year basis in the second half of 2004 as a result of the acquisitions of Corvigo and Incubator in March 2004.



Merger-related and other costs. Merger-related and other costs of $469,000 for the
three and six months ended June 30, 2004 consist of $376,000 of severance costs for Tumbleweed employees terminated in connection with the Corvigo and Incubator acquisitions and the sale of Tumbleweeds Indian subsidiary in June 2004, $26,000
for a loss on the sale of Tumbleweeds Indian subsidiary, and $67,000 of other merger-related costs. Merger-related and other costs of $1.9 million for the three and six months ended June 30, 2003, consist of $891,000 of severances for
Tumbleweed employees terminated in connection with the Valicert acquisition and a $996,000 charge related to the fair value of anticipated losses on an operating lease. The operating lease was assumed during the acquisition of Interface, Inc. in
2000 and covers approximately 13,000 square feet of office space in Slough, United Kingdom. The lease is for a term ending in 2020 with quarterly rent payments of approximately $65,000. This office space had been subleased to a tenant who was
providing Tumbleweed with quarterly rent payments of approximately $65,000 until the sublease was terminated effective July 2003. Anticipated future sublease rental income is not expected to cover the rent expense due to a weak office rental market
in and around Slough. We expect to continue to incur merger-related and other costs in the third quarter of 2004 as we incur costs related to the integration of Tumbleweed, Incubator, and Corvigo.



Other income, net. Other income, net, is primarily comprised of interest income earned
on investment securities and interest expense incurred on outstanding debt. Additionally in the three months ended June 30, 2004, this category included the recovery of $66,000 due from current and former employees previously deemed uncollectable,
and in the three months ended March 31, 2004, included approximately $100,000 from the sale of a product line. The increase in other income, net, for the three and six months ended June 30, 2004 as compared to the three and six months ended June 30,
2003 was primarily due to these two items.



LIQUIDITY AND CAPITAL RESOURCES



Since inception, we have financed our operations
primarily through the issuance of equity securities. As of June 30, 2004, we had approximately $21.6 million in cash and cash equivalents.



Net cash used in operating activities for the six months ended June 30, 2004 decreased to $138,000 from $3.8 million for the same six months in 2003. Net
cash used in operating activities for the six months ended June 30, 2004 was primarily the result of our net loss of $3.8 million and adjustments to reconcile net loss to net cash used in operating activities including a decrease in accounts
receivable balances of $2.7 million and non-cash charges for depreciation and amortization expenses of $2.3 million and stock-based compensation expense of $381,000, offset by a decrease in accounts payable, accrued liabilities, and other long-term
liabilities of $1.7 million. The reduction in net cash used in operating activities was primarily due to a reduction in our net loss of $2.8 million and increases in non-cash charges for depreciation and amortization expenses and stock-based
compensation expense



Net cash used in investing activities for
the six months ended June 30, 2004 was $4.0 million. Net cash provided by investing activities for the six months ended June 30, 2003 was $425,000. Net cash used in investing activities for the six months ended June 30, 2004 was comprised of $3.4
million for the acquisitions of Incubator and Corvigo, net of cash acquired, and $582,000 of purchases of property and equipment. The $3.4 million outflow for the acquisitions of Incubator and Corvigo includes the impact of a $6.0 million cash
payment to Corvigo shareholders as part of the purchase price for Corvigo. Net cash provided by investing activities for the six months ended June 30, 2004 was comprised of inflows related to the acquisition of Valicert, partially offset by
purchases of property and equipment.



Net cash provided by
financing activities for the six months ended June 30, 2004 was $394,000. Net cash used in financing activities for the six months ended June 30, 2003 was $15,000. Net cash provided by financing activities for the six months ended

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES



June 30, 2004 was comprised of an inflow of $528,000 for the proceeds from the issuance of common stock as a result
of the exercises of stock options and warrants, partially offset by an outflow of $134,000 related to repayments on outstanding debt originally assumed in the acquisition of Valicert. Net cash used in financing activities for the six months ended
June 30, 2003 resulted primarily from the repayment of outstanding debt of $79,000 partially offset by proceeds of $64,000 as a result of the issuance of common stock as a result of the exercises of stock options and warrants.



As of June 30, 2004, our principal commitments consisted of obligations
related to outstanding operating leases, a bank loan, and unconditional purchase obligations. We do not anticipate a substantial increase in operating lease obligations in the immediate future.



In June 1999, we entered into an operating lease covering approximately
40,000 square feet of office space in Redwood City, California that was scheduled to expire in November 2004. During the three months ended September 30, 2003 we renewed this lease in advance of the scheduled termination date at a lower monthly rent
cost in exchange for an extension of the lease term. The renewed lease expires in July 2008 with current monthly rent payments of approximately $73,000.



As a result of the Interface acquisition, we assumed an operating lease in Slough, United Kingdom. The lease is for a term ending in 2020 with current
quarterly rent payments of approximately $65,000. We subleased this office space to a tenant who was providing us with quarterly rent payments of approximately $65,000 until the sublease was terminated effective July 2003. Anticipated future
sublease rental income is not expected to cover the rent expense due to a weak office rental market in and around Slough. In the second quarter of 2003 we recognized a charge of $996,000 related to potential losses on this lease that was included in
our consolidated statement of operations as Merger-related and other costs. We are currently attempting to find a new sublessee.



In the acquisition of Valicert, we assumed debt of $855,000 resulting from equipment leases with two financing companies. During the three months ended
September 30, 2003 this debt was refinanced with an $800,000 loan from the same bank from whom we previously had obtained equipment loan facilities. The new debt bears interest at prime rate plus 0.63%, is due and payable in 36 equal monthly
installments, and is secured by certain of our assets.



Our
capital requirements depend on numerous factors, including revenue generated from operations and market acceptance of our products and services, the resources devoted to the development of our products and services and the resources devoted to sales
and marketing. We believe that our existing capital resources should enable us to maintain our current and planned operations for at least the next twelve months. Our current cash reserves, however, may be insufficient if we experience either lower
than expected revenues or extraordinary or unexpected cash expenses, or for other reasons. Funding, if pursued, may not be available on acceptable terms or at all. If adequate funds are not available, we may be required to curtail significantly or
defer one or more of our operating goals or programs, or take other steps that could harm our business or future operating results.



We will continue to consider future financing alternatives, which may include the incurrence of indebtedness, additional public or private equity
offerings or an equity investment by a strategic partner; however, we have no present commitments or arrangements assuring us of any future equity or debt financing. Additionally, equity or debt financing may not be available to us on favorable
terms, if at all.



We regularly evaluate acquisition candidates
that have products, technologies, or customers that may complement our own, and expect to continue this practice.



At June 30, 2004, we did not have any relationships with unconsolidated entities or financial partnerships, such as entities often referred to as
structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes. As such, we are not exposed to any financing,
liquidity, market or credit risk that could arise if we had engaged in such relationships.



Contractual Obligations and Commercial Commitments



Future cash payments for contractual obligations and commercial commitments as of June 30, 2004, are as follows (in thousands):

be offset by sublease payments of $103,000 in 2004 and $34,000 in 2005.

RISKS AND UNCERTAINTIES THAT YOU SHOULD CONSIDER BEFORE INVESTING IN TUMBLEWEED.



We have a history of losses and may experience losses in the future.



Our prospects must be considered in light of the risks, expenses, delays and
difficulties frequently encountered by companies engaged in new and rapidly evolving technology markets like ours. We incurred net losses of $9.2 million, $20.9 million, and $114.2 million in 2003, 2002, and 2001, respectively. As of June 30, 2004,
we had incurred cumulative net losses of $283.1 million.



Our
success may depend in large part upon the adoption and utilization of our products and technology, as well as our ability to effectively maintain existing relationships and develop new relationships with customers and strategic partners. If we do
not succeed in doing so, we may not achieve or maintain profitability on a timely basis or at all. In particular, we intend to expend significant financial and management resources on product development, sales and marketing, strategic
relationships, technology and operating infrastructure. As a result, we may incur additional losses and continued negative cash flow from operations for the foreseeable future and may not achieve or maintain profitability.



We expect to continue making strategic investments and acquisitions, which may involve
substantial costs, may substantially dilute our existing investors, and may fail to yield anticipated benefits.



We are continuously evaluating investments in complementary technologies and businesses. Acquisitions of companies, divisions of companies, or products,
including our acquisitions of Valicert, Incubator, and Corvigo entail numerous risks, including:



| | potential inability to successfully integrate acquired operations and products or to realize cost savings or other anticipated benefits from integration;
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------



| | diversion of managements attention;
|- | ------------------------------------



| | loss of key employees of acquired operations;
|- | ---------------------------------------------



| | coordinating sales and pricing efforts to effectively communicate the value and capabilities of the combined company;
|- | ---------------------------------------------------------------------------------------------------------------------



| | integrating technologies and product lines;
|- | -------------------------------------------



| | the difficulty of assimilating geographically dispersed operations and personnel of the acquired companies;
|- | -----------------------------------------------------------------------------------------------------------



| | the potential disruption of our ongoing business;
|- | -------------------------------------------------



| | expenses related to such integration;
|- | -------------------------------------



| | the correct assessment of the relative percentages of in-process research and development expense that can be immediately written off as compared to the amount which must be
amortized over the appropriate life of the asset;
|- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | the impairment of relationships with employees and customers of either an acquired company or our business; and
|- | ---------------------------------------------------------------------------------------------------------------



| | the potential unknown liabilities associated with acquired business.
|- | --------------------------------------------------------------------



As a result of acquisitions, we may acquire significant assets that include goodwill and other purchased intangibles. The testing of these intangibles
under established accounting guidelines for impairment requires significant use of judgment and assumptions. Changes in business conditions could require adjustments to the valuation of these assets.



If we do not successfully optimize our marketing and distribution capacity, our business
could be harmed.



If we do not optimize our methods of
marketing and selling our products, it could significantly limit our ability to compete successfully against current and future competitors. The markets in which we compete are intensely competitive and rapidly changing, in part because third
parties (such as hackers and spammers) whose timing and methods are somewhat unpredictable can have a significant impact on customer demand. Vendors in our markets use different methods of marketing and distribution in order to meet expected
customer demand. For example, our competitors in the anti-spam market include multiple software-only vendors, appliance-only vendors, and service providers, as well as vendors that offer a combination of some or all of the foregoing. Moreover,
vendors offerings range from single-function point products and services to more sophisticated and scalable multi-functional offerings. In addition, pricing and other terms and conditions of sales contracts also vary considerably among our
competition. Because it is difficult to predict demand in our rapidly changing markets, we may not be able to manage our marketing and sales efforts in an optimal way, which may disadvantage our business in comparison to competitors.

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES



Additional competitive factors in our industry include product performance and integration, platform
coverage, worldwide sales infrastructure and global technical support. Some of our competitors have greater financial, technical, sales, marketing and other resources than we do, as well as greater name recognition and a larger installed customer
base. Additionally, some of these competitors have research and development capabilities that may allow them to develop new or improved products that may compete with product lines we market and distribute.



We expect that the market for secure Internet messaging software products
will become more consolidated with larger companies being better positioned to compete in such an environment in the long term. As this market continues to develop, a number of companies with greater resources than ours could attempt to increase
their presence in this market by acquiring or forming strategic alliances with our competitors or business partners.



Our success will depend on our ability to adapt to these competing forces, to develop more effective products more rapidly and less expensively than our
competitors, and to educate potential customers as to the benefits of licensing our products rather than developing their own products. Competitors could introduce products with superior features, scalability and functionality at lower prices than
our products and could also bundle existing or new products with other more established products in order to compete with us. In addition, because there are relatively low barriers to entry for the software market, we expect additional competition
from other established and emerging companies. Increased competition is likely to result in price reductions, reduced gross margins and loss of market share, any of which could harm our business.



Our success depends on our ability to grow and develop our indirect distribution channels
and the inability to do so could adversely affect future operating results.



Our failure to increase the number of our indirect distribution channels could have a material adverse effect on our business, operating results, and financial condition. We must increase the number of strategic and
other third-party relationships with vendors of Internet-related systems and application software, resellers and systems integrators. Our existing or future channel partners may choose to devote greater resources to marketing and supporting the
products of other companies.



The volume of spam may not continue to grow
rapidly, which may adversely affect the market for anti-spam solutions.



Although the volume of spam has grown rapidly during the last several years, it may not continue to do so because of recently enacted anti-spam legislation, enforcement efforts under that legislation, and
collaborative efforts by leaders of the email provider industry, as well as the potential development of new and successful anti-spam technologies. Accordingly, the market for anti-spam solutions may not continue to grow rapidly and may in fact
decline, which may adversely affect our business.



Contractual issues may
arise during the negotiation of license agreements that may delay the anticipated closure of a transaction and our ability to recognize revenue as anticipated.



Because we focus on selling enterprise-wide software products to enterprises and government entities, the process of
contractual negotiation is critical and may be lengthy. Additionally, several factors may require us to defer recognition of license revenue for a significant period of time after entering into a license agreement, including instances where we are
required to deliver either unspecified additional products or specified upgrades for which we do not have vendor-specific objective evidence of fair value. Although we have a standard software license agreement that provides for revenue recognition
to the extent that (i) delivery has taken place, (ii) collectibility from the customer is reasonably assured, and (iii) no significant future obligations or customer acceptance rights exist, customer negotiations and revisions to these terms could
impact our ability to recognize revenues at the time of delivery.



Many enterprise customers negotiate software licenses near the end of each quarter. In part, this is because enterprise customers are able, or believe that they are able, to negotiate lower prices and more favorable terms at that time. Our
reliance on a large portion of software license revenue occurring at the end of the quarter and the increase in the dollar value of transactions that occur at the end of a quarter can result in increased uncertainty relating to quarterly revenues.
Due to end-of-period variances, forecasts may not be achieved, either because expected sales do not occur or because they occur at lower prices or on terms that are less favorable to us.



A limited number of customers account for a high percentage of our revenue, and the failure to maintain or expand these relationships
could adversely affect our future revenue.



The loss of
one or more of our major customers, the failure to attract new customers on a timely basis or a reduction in revenue associated with existing or proposed customers would harm our future revenue and prospects. During the three months ended June 30,
2004 and 2003, five customers comprised approximately 15% and 22% of our revenue, respectively. During the six months ended June 30, 2004 and 2003, five customers comprised approximately 17% and 19% of our revenue, respectively.

Fluctuations in our quarterly operating results may not be predictable and may result in significant volatility in
our stock price.



Our product revenue has fluctuated and
our quarterly operating results will continue to fluctuate based on, among other things, the timing of the execution and termination of customer agreements in a given quarter. In addition, we have experienced, and expect to continue to experience,
fluctuations in revenue and operating results from quarter to quarter for other reasons, including, but not limited to:



| | target customers electing to adopt and implement our technology;
|- | ----------------------------------------------------------------



| | the substantial decrease in information technology spending in general, and among our target customers in particular;
|- | ---------------------------------------------------------------------------------------------------------------------



| | customers choosing to delay their purchase commitments or purchase in smaller amounts than expected due to a general downturn in the economy;
|- | ---------------------------------------------------------------------------------------------------------------------------------------------



| | our ability to continue to license our patents, the timing of such licenses, and the costs necessary to defend our patents;
|- | ---------------------------------------------------------------------------------------------------------------------------



| | the amount and timing of operating costs and capital expenditures relating to our business, operations and infrastructure;
|- | --------------------------------------------------------------------------------------------------------------------------



| | our ability to accurately estimate and control costs;
|- | -----------------------------------------------------



| | our ability to timely collect fees owed by customers;
|- | -----------------------------------------------------



| | the announcement or introduction of new or enhanced products and services in the secure content management, content security, secure online communications, or document delivery
markets; and
|- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | acquisitions that we complete or propose.
|- | -----------------------------------------



As a result of these factors, we believe that quarter-to-quarter comparisons of our revenue and operating results are not necessarily meaningful, and that
these comparisons may not be accurate indicators of future performance. We may not be able to accurately forecast our revenue or expenses. Because our staffing and operating expenses are based on anticipated revenue levels, and because a high
percentage of our costs are fixed, small variations in the timing of the recognition of specific revenue could cause significant variations in operating results from quarter to quarter. In addition, many of our customers delay purchases of our
products until the end of each quarter. If we are unable to adjust spending in a timely manner to compensate for any unexpected revenue shortfall, any significant revenue shortfall would likely have an immediate negative effect on our operating
results. Moreover, we believe the challenges and difficulties that we face, as outlined above with respect to financial forecasts, also apply to securities analysts that may publish estimates of our financial results. Our operating results in one or
more future quarters may fail to meet the expectations of securities analysts or investors due to any of a wide variety of factors, including fluctuations in financial ratios or other metrics used to measure our performance. If this occurs, we would
expect to experience an immediate and significant decline in the trading price of our stock.



Economic conditions could adversely affect our ability to maintain and increase revenue.



Our revenue and profitability or loss depends on the overall demand for our products, our intellectual property, and our services, particularly within the
industries in which we offer specific versions of our products. Because our sales are primarily to customers in the financial services, health care, and government industries, our business depends on the overall economic conditions and the economic
and business conditions within these industries. Any weakening of the global economy, the information technology industry in particular, and the weakening of the business conditions within the above industries could cause a decrease in our license
revenues. A softening of demand for information technology spending caused by a continued weakening of the economy, domestically or internationally, may result in a decrease in revenues and continued losses.



In addition, the financial, political, economic and other uncertainties
following the terrorist attacks upon the United States and the United States involvement in Iraq have led to a further weakening of the global economy, and have created an uncertain economic environment. We cannot predict the impact of these
events, any subsequent terrorist acts or any related military action, on our customers or business. Subsequent terrorist acts and/or the threat of future outbreak or continued escalation of hostilities involving the United States or other countries
could adversely affect spending on information technology and on our software license revenue, as well as have an adverse effect on our business, financial condition or results of operations.



Companies changes to their procurement cycles in response to the Sarbanes-Oxley Act
of 2002, may delay sales of our products.



Many companies
have recently instituted changes to their corporate governance practices, internal control policies and audit committee procedures in response to the Sarbanes-Oxley Act of 2002. These changes, in turn, may require increased oversight by these
companies of their procurement practices. To the extent our potential customers must direct additional management attention and resources to their procurement processes, our sales cycle could lengthen and our revenue could be adversely affected.



The terms of any financing we may obtain could result in substantial
dilution of existing stockholders.



In the future, we may
be required or elect to seek additional financing to fund our operations. Factors such as the commercial success of our existing products and services, the timing and success of any new products and services, the progress of our research and
development efforts, our results of operations, the status of competitive products and services, and the timing and success of potential strategic alliances or potential opportunities to acquire or sell technologies or assets may require us to seek
additional



22

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES



funding sooner than we expect. In the event that we require additional cash, we may not be able to secure additional
financing on terms that are acceptable to us, especially in light of uncertainty in the current market environment, and we may not be successful in implementing or negotiating such other arrangements to improve our cash position. If we raise
additional funds through the issuance of equity or convertible debt securities, the percentage ownership of our stockholders would be reduced and the securities we issue might have rights, preferences and privileges senior to those of our current
stockholders. If adequate funds were not available on acceptable terms or at all, our ability to achieve or sustain positive cash flows, maintain current operations, fund any potential expansion, take advantage of new opportunities, develop or
enhance products or services, or otherwise respond to competitive pressures could be significantly limited.



Our certificate of incorporation and bylaws contain provisions that could discourage or prevent an acquisition of us, which could depress our stock price.



The provisions of our certificate of incorporation and bylaws, as well as
provisions of Delaware law, may discourage or prevent an acquisition or disposition of our business. Our certificate of incorporation and bylaws may inhibit changes of control that are not approved by our Board of Directors. These provisions could
limit the price that investors might be willing to pay in the future for shares of our common stock. In particular, our certificate of incorporation provides for a classified Board of Directors and prohibits stockholder action by written consent.
These provisions require advance notice for nomination of directors and stockholders proposals. In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law. In general, this law prevents a
person who becomes the owner of 15% or more of the corporations outstanding voting stock from engaging in specified business combinations for three years unless specified conditions are satisfied. In addition, our certificate of incorporation
allows our Board of Directors to issue preferred stock without further stockholder approval. This could have the effect of delaying, deferring or preventing a change in control. The issuance of preferred stock also could effectively limit the voting
power of the holders of our common stock.



We may be unable to adequately
protect our intellectual property rights or may be subject to claims of patent infringement, either of which could result in substantial costs to us.



We currently rely on a combination of patents, trade secrets, copyrights, trademarks and licenses, together with non-disclosure and confidentiality
agreements to establish and protect our proprietary rights in our products. We hold certain patent rights with respect to some of our products. Our existing patents or trademarks, as well as any future patents or trademarks obtained by us, may be
challenged, invalidated or circumvented, or our competitors may independently develop or patent technologies that are substantially equivalent or superior to our technology. We also rely on unpatented trade secrets and other unpatented proprietary
information. Although we take precautionary measures to maintain our unpatented proprietary information, others may acquire equivalent information or otherwise gain access to or disclose our proprietary information, and we may be unable to
meaningfully protect our rights to our proprietary information. As a result, our operating results could suffer.



Third parties could assert patent or other intellectual property infringement claims against us and the cost of responding to such assertions, regardless
of their validity, could be significant. We may increasingly be subject to claims of intellectual property infringement as the number of our competitors grows and the functionality of their products and services increasingly overlap with ours. In
addition, we may infringe upon patents that may be issued to third parties in the future. It may be time consuming and costly to defend ourselves against any of these claims and we may not prevail. Furthermore, parties making such claims may be able
to obtain injunctive or other equitable relief that could block our ability to further develop or commercialize some or all of our products in the United States and abroad. In the event of a claim of infringement, we may be required to obtain one or
more licenses from or pay royalties to third parties. We may be unable to obtain any such licenses at a reasonable cost, if at all. Defense of any lawsuit or failure to obtain such license could harm our business.



The enforcement of our intellectual property rights, especially through patent
infringement lawsuits we may initiate, could result in substantial litigation costs and ultimately may not result in additional revenue to us or a favorable judicial determination.



Since 1999 we have aggressively pursued cases of potential infringement by third parties of our patents and other
intellectual property rights. The enforcement process is costly and requires significant management attention. These costs are expensed during the period incurred, and the costs of pursuing the litigation may not be directly matched with the related
patent license agreement revenue, if any. In addition, our enforcement of our rights may increase the risk of adverse claims, with or without merit, which could be time consuming to defend, result in costly litigation, divert managements
attention and resources, limit the use of our services, or require us to enter into royalty or license agreements. In addition, such counter-claims asserted by these third parties may be found to be valid and could result in an injunction or damages
against us. Our ability to prevail in this litigation is inherently uncertain, and if we were subject to an adverse judicial determination, our ability to protect our products and to secure related licensing or settlement revenue could be lost.

Failure to license necessary third party software incorporated in our products could cause delays or reductions in
our sales.



We license third party software that we
incorporate into our products. These licenses may not continue to be available on commercially reasonable terms, or at all. Some of this technology would be difficult to replace. The loss of any such license could result in delays or reductions of
our applications until we identify, license and integrate or develop equivalent software. If we are required to enter into license agreements with third parties for replacement technology, we could face higher royalty payments and our products may
lose certain attributes or features. In the future, we might need to license other software to enhance our products and meet evolving customer needs. If we are unable to do this, we could experience reduced demand for its products.



We are a defendant in two purported securities class action lawsuits that could divert
management attention and resources or eventually expose us to liability.



In June 2003, we were served with a summons and first amended complaint, captioned Liu v. Credit Suisse First Boston, et alia, alleging the violation of federal and state securities laws, purportedly on behalf
of persons who acquired our common stock (other than purchasers of our initial public offering) from August 6, 1999 to October 18, 2000. The case is now pending in the United States District Court for the Southern District of New York. In May 2004,
the Court granted plaintiffs motion for leave to file a second amended complaint. Tumbleweed and the other defendants intend to file motions to dismiss this case pursuant to Fed. R. Civ. P. 12(b). An adverse outcome in this case could harm our
business and operating results. Moreover, the costs in defending this lawsuit could harm future operating results. The accompanying consolidated financial statements do not include a reserve for any potential loss, as we do not consider a loss to be
probable at this time. An adverse outcome could harm our business and operating results. Moreover, the costs in defending this lawsuit could harm future operating results.



In December 2001, certain plaintiffs filed a class action lawsuit in the United States District Court for the Southern
District of New York on behalf of purchasers of the common stock of Valicert, alleging violations of federal securities laws. In re Valicert, Inc. Initial Public Offering Securities Litigation, No. 01-CV-10889 (SAS) (S.D.N.Y.), related to In re
Initial Public Offering Securities Litigation, No. 21 MC 92 (SAS). In June 2003, Valicert accepted a settlement proposal presented to all issuer defendants in this case. Under the proposed settlement, the plaintiffs will dismiss and release all
claims against the Valicert Defendants in exchange for a contingent payment guaranty by the insurance companies collectively responsible for insuring the issuers in all the consolidated cases, and the assignment or surrender of control to the
plaintiffs of certain claims the issuer defendants may have against the underwriters. Under the guaranty, the insurers will be required to pay the amount, if any, by which $1 billion exceeds the aggregate amount ultimately collected by the
plaintiffs from the underwriter defendants in all of the cases. If the plaintiffs fail to recover $1 billion and payment is required under the guaranty, Valicert would be responsible to pay its pro rata portion of the shortfall, up to the amount of
the deductible retention under its insurance policy, which is $500,000. The timing and amount of payments that Valicert could be required to make under the proposed settlement will depend on several factors, principally the timing and amount of any
payment required by the insurers pursuant to the $1 billion guaranty. The proposed settlement is subject to approval of the Court, which cannot be assured. Failure of the Court to approve the settlement followed by an adverse outcome could harm our
business and operating results. Moreover, the costs in defending this lawsuit could harm future operating results. The accompanying consolidated financial statements do not include a reserve for any potential loss, as we do not consider a loss to be
probable at this time. An adverse outcome could harm our business and operating results. Moreover, the costs in defending this lawsuit could harm future operating results.



If we lose the services of executive officers or other key employees, our ability to develop our business and secure customer
relationships will suffer.



We are substantially dependent
on the continued services and performance of our executive officers and other key personnel. The loss of the services of any of our executive officers or other key employees, including recent additions to our management team as a result of our
acquisitions of Incubator and Corvigo, could significantly delay or prevent the achievement of our development and strategic objectives. We do not have long-term employment agreements with any of our key personnel. The loss of services of any of our
executive officers or other key personnel could significantly harm our business and prospects.



Our international business exposes us to additional risks that may result in future additional costs or limit the market for product sales.



Products and services provided to Tumbleweeds international customers accounted for 11% and 4% of our revenues for the
three months ended June 30, 2004 and 2003, respectively and 12% and 7% of our revenues for the six months ended June 30, 2004 and 2003, respectively. Conducting business outside of the United States subjects us to additional risks, including:



| | changes in regulatory requirements;
|- | -----------------------------------



| | reduced protection of intellectual property rights;
|- | ---------------------------------------------------



| | evolving privacy laws;
|- | ----------------------



| | tariffs and other trade barriers;
|- | ---------------------------------



| | difficulties in staffing and managing foreign operations;
|- | ---------------------------------------------------------

TUMBLEWEED COMMUNICATIONS CORP. AND SUBSIDIARIES



| | problems in collecting accounts receivable; and
|- | -----------------------------------------------



| | difficulties in authenticating customer information.
|- | ----------------------------------------------------



Managing these risks may subject us to additional costs that may not be justified in light of the market opportunity, and the inability to comply with or
manage foreign laws and related risks may preclude or limit sales in foreign jurisdictions. In addition, the recent outbreak of severe acute respiratory syndrome, or SARS, that began in China, Hong Kong, Singapore and Vietnam may have a negative
impact on our operations by factors such as reduced sales in international channels.



We rely on public key cryptography and other security techniques that could be breached, resulting in reduced demand for our products and services.



A requirement for the continued growth of electronic commerce is the secure transmission of confidential information over
public networks. We rely on public key cryptography, an encryption method that utilizes two keys, a public and private key, for encoding and decoding data, and on digital certificate technology, to provide the security and authentication necessary
for secure transmission of confidential information. Regulatory and export restrictions may prohibit us from using the strongest and most secure cryptographic protection available, and thereby may expose us or our customers to a risk of data
interception. A party who is able to circumvent our security measures could misappropriate proprietary information or interrupt our or our customers operations. Any compromise or elimination of our security could result in risk of loss or
litigation and possible liability and reduce demand for our products and services.



ITEM 3QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK



We currently do not use financial instruments to hedge operating expenses in Bulgaria, Japan, the Netherlands, Switzerland, or the United Kingdom
denominated in the respective local currency. We assess the need to utilize financial instruments to hedge currency exposures on an ongoing basis.



We do not use derivative financial instruments for speculative trading purposes, nor do we hedge our foreign currency exposure in a manner that entirely
offsets the effects of changes in foreign exchange rates. We regularly review our hedging program and may as part of this review determine at any time to change our hedging program.



Interest Rate Sensitivity



The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive from our investments
without significantly increasing risk. Some of the securities that we have invested in may be subject to market risk. This means that a change in prevailing interest rates may cause the fair value of the investment to fluctuate. For example, if we
hold a security that was issued with a fixed rate equal to the then-prevailing interest rate and the prevailing interest rate later rises, the fair value of our investment will decline. To minimize this risk, we maintain our portfolio of cash
equivalents in commercial paper and money market funds. In general, our investments are not subject to market risk because the interest paid on these funds fluctuates with the prevailing interest rate. As of June 30, 2004, none of our cash
equivalents were subject to market risk.



ITEM 4CONTROLS AND PROCEDURES



(a) Evaluation of disclosure controls and procedures.



Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-154(e) and 15(d)-14(c) under the Securities
Exchange Act of 1934, as amended (the Exchange Act) as of June 30, 2004, and, based on that evaluation, our chief executive officer and chief financial officer concluded that, as of June 30, 2004, our disclosure controls and procedures
are effective in recording, processing, summarizing and reporting, on a timely basis, information required to be disclosed by us in the reports we file under the Exchange Act



(b) Changes in internal controls.



There have not been any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the
Exchange Act) during the three months ended June 30, 2004 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART IIOTHER INFORMATION



ITEM 1LEGAL PROCEEDINGS



In December 2001, certain plaintiffs filed a class action lawsuit in the United States District Court for the Southern District of New York on behalf of purchasers of the common stock of Valicert, alleging violations
of federal securities laws. In re Valicert, Inc. Initial Public Offering Securities Litigation, No. 01-CV-10889 (SAS) (S.D.N.Y.), related to In re Initial Public Offering Securities Litigation, No. 21 MC 92 (SAS). The operative amended complaint is
brought on purported behalf of all persons who purchased Valicert common stock from the date of its July 27, 2000 initial public offering through December 6, 2000. It names as defendants Valicert, its former chief executive officer, its chief
financial officer (the Valicert Defendants), as well as an investment banking firm that served as an underwriter for the IPO. The complaint alleges liability under Sections 11 and 15 of the Securities Act of 1933 and Sections 10(b) and
20(a) of the Securities Exchange Act of 1934, on the grounds that the registration statement for the IPO did not disclose that: (1) the underwriter agreed to allow certain customers to purchase shares in the IPO in exchange for excess commissions to
the paid to the underwriter; and (2) the underwriter arranged for certain customers to purchase additional shares in the aftermarket at predetermined prices. The complaint also appears to allege that false or misleading analyst reports were issued.
The complaint does not claim any specific amount of damages. Similar allegations have been made in lawsuits relating to more than 300 other initial public offerings conducted in 1999 and 2000, all of which have been consolidated for pretrial
purposes. In February 2003, the Court issued a ruling on all defendants motions to dismiss, denying Valicerts motion to dismiss the claims under the Securities Act of 1933, but granting Valicerts motion to dismiss the claims under
the Securities Exchange Act of 1934.



In June 2003, Valicert
accepted a settlement proposal presented to all issuer defendants in this case. Under the proposed settlement, the plaintiffs will dismiss and release all claims against the Valicert Defendants in exchange for a contingent payment guaranty by the
insurance companies collectively responsible for insuring the issuers in all the consolidated cases, and the assignment or surrender of control to the plaintiffs of certain claims the issuer defendants may have against the underwriters. Under the
guaranty, the insurers will be required to pay the amount, if any, by which $1 billion exceeds the aggregate amount ultimately collected by the plaintiffs from the underwriter defendants in all of the cases. If the plaintiffs fail to recover $1
billion and payment is required under the guaranty, Valicert would be responsible to pay its pro rata portion of the shortfall, up to the amount of the deductible retention under its insurance policy, which is $500,000. The timing and amount of
payments that Valicert could be required to make under the proposed settlement will depend on several factors, principally the timing and amount of any payment required by the insurers pursuant to the $1 billion guaranty. The proposed settlement is
subject to approval of the Court, which cannot be assured. The accompanying consolidated financial statements do not include a reserve for any potential loss, as Tumbleweed does not consider a loss to be probable at this time.



In June 2003, we were served with a summons and first amended complaint,
captioned Liu v. Credit Suisse First Boston, et alia, alleging the violation of federal and state securities laws, purportedly on behalf of persons who acquired our common stock (other than purchasers of ours initial public offering) from

and the other defendants intend to file motions to dismiss this case pursuant to Fed. R. Civ. P. 12(b). An adverse outcome in this case could harm our business and operating results. Moreover, the costs in defending this lawsuit could harm future
operating results. The accompanying consolidated financial statements do not include a reserve for any potential loss, as we do not consider a loss to be probable at this time.



All costs incurred as a result of these legal proceedings and claims are charged to expense as incurred.



We indemnify our customers from third party claims of intellectual property
infringement relating to the use of our products. Historically, costs related to these guarantees have not been significant and we are unable to estimate the potential impact of these guarantees on our future results of operations.
