Notes to Unaudited Condensed Consolidated Financial Statements



|1. | Basis of Presentation
|-- | ---------------------

The accompanying unaudited condensed consolidated financial statements of SciClone Pharmaceuticals, Inc.
(SciClone or the Company) have been prepared in conformity with generally accepted accounting principles in the United States (GAAP) consistent with those applied in, and should be read in conjunction with, the
audited financial statements for the year ended December 31, 2009 included in the Companys Form 10-K as filed with the Securities and Exchange Commission. The Company prepared the unaudited condensed consolidated financial statements
following the requirements of the Securities and Exchange Commission for interim reporting. The interim financial information reflects all adjustments, consisting only of normal recurring adjustments, which are, in the opinion of management,
necessary for a fair presentation of the results for the interim periods presented and are not necessarily indicative of results for subsequent interim periods or for the full year. The condensed consolidated balance sheet data at December 31,
2009 is derived from the audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements.

The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries.
Material intercompany accounts and transactions have been eliminated.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make judgments, assumptions and
estimates that affect the amounts reported in our condensed consolidated financial statements and accompanying notes. Actual results could differ significantly from those estimates.

Revenue Recognition

The Company recognizes revenue from product sales at the time of delivery. There are no significant customer acceptance
requirements or post-shipment obligations on the part of the Company, except for sales to a new market where acceptance requirements may have to be met. Sales to importing agents or distributors are recognized at time of shipment when title to the
product is transferred to them. Importing agents or distributors do not have contractual rights of return except under limited terms regarding product quality. However, the Company may replace products that have expired or are deemed to be damaged
or defective when delivered. The Company estimates expected returns primarily on historical patterns. Historically, the Company has had no product returns of damaged, defective or expired product. As such, no amount was accrued for product returns
as of June 30, 2010 and December 31, 2009 in the accompanying condensed consolidated balance sheets. Payments by the importing agents and distributors are not contingent upon sale to the end user by the importing agents or distributors.
Amounts invoiced relating to arrangements where collectibility is uncertain and revenue cannot be recognized are reflected on the Companys balance sheet as deferred revenue and recognized as the applicable revenue recognition criteria are
satisfied.

Research and Development Expenses

Research and development costs are expensed as incurred. These costs consist primarily of salaries and other
personnel-related expenses, including associated stock-based compensation, facility-related expenses, depreciation of facilities and equipment, license-related fees, services performed by clinical research organizations and research institutions and
other outside service providers, and the sharing of certain costs for the development of ZADAXIN by the Companys partner, Sigma-Tau Finanziaria S.p.A (Sigma-Tau).

Expenses related to clinical trials generally are accrued based on estimates of work performed or the level of patient
enrollment and activities according to the protocols and agreements. The Company monitors planned protocols, work performed, patient enrollment levels and related activities to the extent possible and adjusts estimates accordingly. Nonrefundable
advance payments for research and development goods or services are recognized as expense as the related goods are delivered or the related services are provided.

Concentrations of Risk

Financial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash
equivalents, investments and accounts receivable. The Company is exposed to credit risk in the event of default by the institutions holding the cash, cash equivalents and investments and by importers with whom the Company has accounts receivable to
the extent of the amounts recorded on the condensed consolidated balance sheet. Substantially all the

Companys cash and cash equivalents are held by financial institutions that the Company believes are of high credit quality. At times, deposits may exceed government insured limits. The
Company has not experienced any losses on its deposits of cash and cash equivalents.

The Peoples
Republic of China (China) uses a tiered method to import and distribute products. The distributors make the sales in the country, but the product is imported for them by licensed importers. For the three months ended June 30, 2010
and 2009, sales to two importing agents in China accounted for 98% and 97% of the Companys product sales, respectively. For the six months ended June 30, 2010 and 2009, sales to three and two importing agents in China accounted for 93%
and 97%, of the Companys product sales, respectively. No other importer accounted for more than 10% of sales for the six months ended June 30, 2010 or 2009. As of June 30, 2010, approximately $21.4 million, or 98%, of the
Companys accounts receivable were attributable to three importing agents in China. The Company performs on-going credit evaluations of its importers financial condition and generally does not require collateral from its importers.

Net Income Per Share

Basic net income per share has been computed by dividing net income by the weighted-average number of shares of common
stock outstanding for the period. Diluted net income per share is computed by dividing net income by the weighted-average number of common equivalent shares outstanding for the period. Diluted net income per share includes any dilutive impact from
stock options and warrants outstanding using the treasury stock method.

The following is a reconciliation of
the numerator and denominators of the basic and diluted net income per share computations (in thousands, except per share amounts):

assumed exercise of these options and warrants calculated under the treasury stock method would have been anti-dilutive. For the six months ended June 30, 2010 and 2009, 2,599,463 and 8,747,053 shares, respectively, related to outstanding stock
options and warrants were excluded from the calculation of diluted net income per share because the effect from the assumed exercise of these options and warrants calculated under the treasury stock method would have been anti-dilutive.

Fair Value of Financial Instruments

The fair value of the Companys financial instruments reflects the amounts that would be received to sell an asset or
paid to transfer a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value estimates presented in this report reflect the information available to the Company as of June 30, 2010 and
December 31, 2009. See Note 3, Fair Value Measurements.

Recent Accounting Guidance

In January 2010, the Financial Accounting Standards Board (FASB) issued FASB Accounting Standards Update
(ASU) No. 2010-06, Fair Value Measurements and Disclosures (Topic 820)Improving Disclosures about Fair Value Measurements. The ASU requires new disclosures about significant transfers in and out of Levels 1 and 2 fair value
measurements and separate disclosures about purchases, sales, issuances and settlements relating to Level 3 fair value measurements. The ASU also clarifies existing disclosure requirements regarding inputs and valuation techniques, as well as the
level of disaggregation for each class of assets and liabilities for which separate fair value measurements should be disclosed. The Company adopted ASU 2010-06 at the beginning of fiscal 2010. The adoption of this ASU did not have a material impact
on the Companys condensed consolidated financial statements.

Reclassifications

The Company reclassified shipping and handling costs related to product shipments of $0.1 million and $0.3 million,
respectively, from sales and marketing expense to cost of product sales for the three and six months ended June 30, 2009, and reclassified $0.1 million and $0.3 million of legal expense from research and development expense to general and
administrative expense for the three and six months ended June 30, 2009, respectively, to conform to the current period presentation. These reclassifications had no effect on the prior periods net income or stockholders equity.

As of June 30, 2010 and
December 31, 2009, available-for-sale securities included $0.4 million and $0.5 million in restricted investments, respectively. The unrealized losses on the Companys restricted Italian state bond investments are mainly as a result of
currency translation. The Company intends to hold its restricted Italian state bond investments until recovery.

As of June 30, 2010 and December 31, 2009, the Companys certificate of deposit for $0.1 million secures
the Companys letter of credit required under its European value added tax filing arrangements.

##### Table of Contents

On June 30, 2010, the Company exercised its right (the Put
Option) under its Auction Rate Securities (ARS) Rights Offer from UBS AG to sell its ARS back to the investment firm at par value for $0.6 million. As of December 31, 2009, the Company had recorded the $0.2 million fair value
of the Put Option in prepaid expenses and other current assets in its condensed consolidated balance sheet. The Companys fair value election was intended to create accounting symmetry with its fair value accounting of the ARS.



|3. | Fair Value Measurements
|-- | -----------------------

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit
price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs
and minimize the use of unobservable inputs. The three levels of input are:

Level 1 - Quoted prices in active
markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable, either
directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of
the assets or liabilities.

Level 3 - Unobservable inputs that are supported by little or no market activity
and that are significant to the fair value of the assets or liabilities.

Where quoted prices are available in
an active market, the Company determines fair value based upon quoted market prices, and classifies these values in level 1 of the valuation hierarchy. If quoted market prices are not available, fair values are based upon observable inputs such as
quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities and are
classified in level 2 of the valuation hierarchy. When quoted prices and observable inputs are unavailable, fair values are based on a market approach using internally developed cash flow models and are classified in level 3 of the valuation
hierarchy. The internally developed cash flow models primarily use, as inputs, estimates for interest rates and discount rates including yields of comparable traded instruments adjusted for illiquidity and other risk factors, amount of cash flows
and expected holding periods of the assets. These inputs reflect the Companys assumptions about the assumptions market participants would use in pricing the assets including assumptions about risk developed based on the best information
available in the circumstances. The Companys assessment of the significance of a particular input to the fair value measurements requires judgment, and may affect the valuation of the assets being measured and their placement within the fair
value hierarchy.

Other financial instruments, including accrued liabilities, are carried at cost, which the
Company believes approximates fair value because of the short-term maturity of these instruments.

The
following table represents the Companys fair value hierarchy for its financial assets (cash equivalents, investments, and other current assets) measured at fair value on a recurring basis (in thousands):

on outstanding balances. The Company is required to meet certain financial covenants, including minimum consolidated revenue, and minimum consolidated earnings before interest and income tax, as defined, and since November 14, 2009, has been
subject to certain minimum fees and interest payments. The Company is also required to meet certain operating covenants that limit its ability to incur liabilities, create liens, make capital expenditures, pay dividends or distributions, make
investments, and dispose of assets and to carry credit insurance. The Company has received a limited waiver to the Credit Facility to waive certain minimum fees and interest payments, and to waive the requirement to maintain a credit insurance
policy. The Company is currently in compliance with the Credit Facility after giving effect to the limited waiver.



|7. | Stock-Based Compensation
|-- | ------------------------

Stock Options

The Company has several stock-based compensation plans (the Plans) that are described in the Companys
Annual Report on Form 10-K for the fiscal year ended December 31, 2009. The Company, under the various equity plans, is permitted to grant incentive stock options, nonstatutory stock options, restricted stock units, performance shares and other
forms of equity compensation. In accordance with the Plans, the options expire ten years from the date of grant. Options are generally granted at fair market value on the date of grant and the portion that is ultimately expected to vest is
recognized as compensation cost over the requisite service period, generally four years, or upon achievement of certain service conditions. Certain options granted under the Plans vest over shorter periods. During the six months ended June 30,
2010, the Company granted options to purchase a total of 1,445,000 shares of common stock and options to purchase 566,000 shares were exercised. During the twelve months ended December 31, 2009, the Company granted options to purchase a total
of 2,269,000 shares of common stock and 999,000 shares were exercised.

The Company has granted certain
performance-based options to purchase shares of the Companys common stock at an exercise price equal to the closing price of a share of the Companys common stock as of the grant date. The options will fully vest upon meeting a
performance goal within an established time frame. If the performance goal is met for the option within the established time frame, the option generally has a ten-year term measured from the date of grant. If the performance goal is not met within
the established time frame, the option expires in its entirety. The grant date fair value per share of the awards has been calculated using the Black-Scholes option pricing model. The Company recognizes expense related to the performance-based
options over the period of time the Company determines that it is probable that the performance goal will be achieved. For the six months ended June 30, 2010, the Company granted a performance-based option to purchase a total of 40,000 shares
of common stock. For the twelve months ended December 31, 2009, the Company granted performance-based options to purchase a total of 340,000 shares of common stock. For the three and six months ended June 30, 2010, the Company recorded
$0.2 million of expense related to performance-based options. There was no option expense recorded for the three or six months ended June 30, 2009 related to the performance-based options.

##### Table of Contents

In May 2010, the Company amended
target-stock-price-based options to purchase 750,000 of the Companys common stock granted to its chief executive officer. The amendment modified the vesting provisions of the options such that
1/36thof the unvested stock options vest monthly over a
three-year period, with initial vesting occurring on June 1, 2010. The fair value of the modified award was estimated using the Black-Scholes option valuation model with the assumptions of a risk-free rate of 2.28%, a volatility factor of
71.83%, a dividend yield of 0%, and an expected life of 5.07 years. The incremental compensation cost resulting from the modification and the remaining unrecognized compensation expense from the original award are being recognized ratably over the
three-year vesting period. The Company recorded expense of $0.1 million for the three months ended June 30, 2010 related to these options.

Employee Stock Purchase Plan

As of June 30, 2010, the Companys Employee Stock Purchase plan has reserved 1,300,000 shares for issuance.
Commencing with the offering period beginning June 1, 2010, the purchase price of the stock shall be equal to 85% of the lower of the fair market value of a share of common stock on the first day of the offering or on the purchase date. Each
offering is for a three-month period. For the three and six months ended June 30, 2010, the Company recorded $4,000 of expense related to the ESPP. There was no ESPP expense recorded during the three or six months ended June 30, 2009.



|8. | Income Taxes
|-- | ------------

Provision for income tax of $0.2 million for both the three months ended June 30, 2010 and 2009, and $0.4 million and
$0.3 million for the six months ended June 30, 2010 and 2009, respectively, related to the Companys foreign operations in China. The Companys statutory tax rate in China was 20% in 2009 and is 22% for 2010. The Company did not
provide for U.S. income taxes on undistributed earnings of its foreign operations that are intended to be permanently reinvested in the foreign operations.



|9. | Subsequent Event
|-- | ----------------

As described below, the Company has been contacted by United States Securities and Exchange Commission (SEC)
and the United States Department of Justice (DOJ) regarding various matters. Consistent with the Companys focus on compliance, the Company intends to cooperate fully with the SEC and DOJ in the conduct of their investigations and
has appointed a special committee of independent directors to oversee the Companys efforts.

On August
5, 2010 SciClone was contacted by the SEC and advised that the SEC has initiated a formal, non-public investigation of SciClone. In connection with this investigation, the SEC issued a subpoena to SciClone requesting a variety of documents and other
information. The subpoena requests documents relating to a range of matters including interactions with regulators and government-owned entities in China, activities relating to sales in China and documents relating to certain company financial and
other disclosures. On August 6, 2010, the Company received a letter from the DOJ indicating that the DOJ was investigating Foreign Corrupt Practices Act issues in the pharmaceutical industry generally, and had received information about the
Companys practices suggesting possible violations.

Overview

SciClone
Pharmaceuticals (NASDAQ: SCLN) is a profit-focused, global specialty pharmaceutical company with a substantial international business, based primarily in the Peoples Republic of China (China), and with a product portfolio of novel
therapies for cancer and infectious diseases. Our strategy is focused on continuing international sales growth, a cost-containing clinical development strategy, and overall expense management. ZADAXIN, our brand of thymalfasin or thymosin alpha 1,
is sold in over 30 countries for the treatment of HBV and HCV, certain cancers and as a vaccine adjuvant. We believe our current cash and investment position and the gross profit from our product sales provide the financial resources to execute on
our strategy for continued growth in our international business and for development of our pipeline of late-stage product candidates.

We plan to expand our commercial operations, currently located primarily in China, with the goal of becoming a significant pharmaceutical
company in Chinas rapidly growing pharmaceutical market. A key part of our strategy is to leverage our decade of experience in China and to grow our international business by adding commercial stage or near term commercial stage products to
our portfolio. We believe we are well-positioned to in-license additional therapeutics for our international business with a focus on China, in part because of our opportunity to commercialize these products utilizing our well established sales and
marketing organization in China. Furthermore, our international growth strategy may include additional partnerships and merger and acquisition transactions for synergistic, commercially attractive products.

We have successfully in-licensed two products that are part of this international commercial growth strategy, DC
Bead® and ondansetron
RapidFilmTM. Our DC Bead product candidate is a novel
treatment for advanced liver cancer which is currently approved in 40 countries worldwide, including Europe and the U.S. We have commercialization rights for this product in China. We commenced a small local registration trial in the first quarter
of 2010, which is expected to enroll approximately 40 advanced liver cancer patients at six liver cancer treatment centers. The primary endpoint is safety and the secondary endpoint is efficacy, as measured by tumor response. If the trial results
are positive, we believe we may receive regulatory approval for DC Bead in 2011.

Our second in-licensed product candidate as
part of this international commercial growth strategy is ondansetron RapidFilm. Ondansetron RapidFilm is an oral thin film formulation of ondansetron, a serotonin 5-HT3 receptor antagonist commonly used to treat and prevent nausea and vomiting
caused by chemotherapy, radiotherapy and surgery. In March 2010, we announced that BioAlliance Pharma had received European Union (EU) approval of ondansetron RapidFilm. BioAlliance Pharma holds all European rights to ondansetron
RapidFilm and was granted regulatory approval under the EU decentralized procedure in 16 major EU countries. We have commercialization rights for this product candidate in China including Hong Kong and Macau, and Vietnam, and we plan to file for
product registration in 2010.

Our clinical development strategy is focused on our portfolio of novel product candidates for
cancer and infectious diseases and includes SCV-07 and thymalfasin. SCV-07, a small molecule synthetic peptide with immunomodulating properties, is being developed for attenuating oral mucositis in subjects with head and neck cancer receiving
concurrent chemotherapy and radiotherapy, and for the treatment of HCV.

##### Table of Contents

Oral mucositis (OM) is a common, painful, debilitating complication of cancer
treatment, and we estimate that total medical costs for the treatment of oral mucositis may reach around $4.2 billion in the U.S. and $10 billion worldwide in 2010. In May 2010, we announced further top-line results from our phase 2 clinical trial
of SCV-07 to modify the course of oral mucositis in patients with head and neck cancer receiving chemoradiotherapy regimens.

The study showed a signal towards delay to onset of severe oral mucositis, the studys primary endpoint, in the higher dose group.
The incidence of severe OM after 5 weeks of chemoradiation was 30% lower in the patients in the high dose treatment arm (0.1 mg/kg; 17 patients) compared to the 20 patients who received placebo (29% vs. 42%). A post hoc data analysis of ulcerative
mucositis (WHO grades 2-4), a major cause of morbidity associated with OM, was also conducted. The high dose of SCV-07 delayed the onset of any ulcerative mucositis in 24% of patients at doses of radiation up to 50Gy (after approximately 5 weeks of
treatment) while 100% of patients in the placebo group suffered from ulcerative mucositis at 35Gy (after approximately 3.5 weeks of treatment). Supportive of these findings, the high dose SCV-07 group also showed improvement over placebo for
exploratory endpoints, including the use of gastric tube feedings, unplanned office or emergency room visits, and breaks in planned course of radiation therapy of one week or longer.

The incidence of severe OM after 5 weeks of chemoradiation was 50% higher in the patients in the low-dose treatment arm (0.02 mg/kg; 20
patients) compared to the 20 patients who received placebo (63% vs. 42%). However, the post hoc data analysis of ulcerative mucositis showed that the low dose of SCV-07 delayed the onset of any ulcerative mucositis in 5% of patients at doses of
radiation up to 50Gy compared to 100% of patients in the placebo group who suffered from ulcerative mucositis at 35Gy. Regarding exploratory endpoints, the low dose group showed similar results to the placebo group. Importantly, both doses of SCV-07
were shown to be safe and well tolerated with no drug-related serious adverse events reported in either arm.

Based on the
study findings, we held successful discussions with the U.S. Food and Drug Administration, and are now planning to initiate a phase 2b study in late 2010 or early 2011. The phase 2b study would include higher doses of SCV-07, have a higher number of
patients in each study arm, and be adequately powered to demonstrate statistical significance.

The second component of the
SCV-07 clinical development program is for the treatment of HCV. This multicenter, multidose, open-label study is designed to evaluate the safety and immunomodulatory effects of SCV-07 as a monotherapy or in combination with ribavirin in
noncirrhotic patients with genotype 1 chronic HCV who have relapsed after at least 44 weeks of treatment with pegylated interferon and ribavirin. The study, which monitors biomarkers of immune activation and HCV viral load dynamics, includes
two treatment cohorts of 20 patients each who receive SCV-07 at a dose of either 0.1 mg/kg or 1.0 mg/kg. The treatment period is approximately eight weeks long, including four weeks of SCV-07 monotherapy followed by four weeks of SCV-07 in
combination with ribavirin. We expect to report top-line results in the second half of 2010. During our previous phase 2a clinical trial of SCV-07 designed to evaluate the effect of SCV-07 on HCV viral load, as well as on other measures of immune
response, SCV-07 demonstrated activity in some treated patients in the higher dosage groups, and the decrease in viral load in these patients was accompanied by an increase in a biomarker which is usually correlated with an immunological response
against HCV. Additionally, SCV-07 was shown to be generally safe and well-tolerated with no dose-limiting toxicities or serious adverse events reported.

We continue to seek development opportunities with ZADAXIN (thymalfasin) focused on vaccine enhancement.
In June 2010, we and our partner, Sigma-Tau Finanziaria S.p.A., announced final results from a clinical study evaluating the potential of ZADAXIN (thymalfasin) to enhance the immune response. ZADAXIN administration given with the MF59 adjuvanted
H1N1 influenza monovalent vaccine, Focetria® from Novartis, led to a statistically significant increase in the
percentage of subjects who seroconverted, when evaluated at 21 days after vaccination, compared with those who received the H1N1 vaccine alone; and at 42 days after vaccination the improvement in titers seen in ZADAXIN-treated patients was
maintained. When evaluated at 84 and 168 days after vaccination, the seroconversion rates were similar for patients receiving ZADAXIN and those receiving vaccine alone. The study was conducted in an immunocompromised population of patients with
end-stage renal disease on chronic hemodialysis. These data indicate that the enhancement effect of ZADAXIN, while significantly higher in the critical first six weeks following vaccination, was reduced at later time points and no longer
significantly different compared to the vaccine alone. Based on the positive study results and potential applications to enhance vaccines targeting other types of infections and diseases, including cancer, we plan to continue discussions with
bio-defense agencies and related groups to determine which vaccines might benefit most from enhancement with ZADAXIN.

Outside
of China, SciClones clinical development strategy is to focus on driving cost-efficient phase 1 and 2 development of promising compounds while seeking development partners for costly phase 3 trials, allowing us to achieve the potential upside
of our portfolio of drug candidates.

We believe our cash and investments as of June 30, 2010 and ongoing revenue
generating business operations will be sufficient to support our current operating plan for at least the next 12 months. Our results may fluctuate from quarter to quarter and we may report quarterly losses in the future.

Recent Accounting Guidance

In January 2010, the Financial Accounting Standards Board (FASB) issued FASB Accounting Standards Update
(ASU) No. 2010-06, Fair Value Measurements and Disclosures (Topic 820)Improving Disclosures about Fair Value Measurements. The ASU requires new disclosures about significant transfers in and out of Levels 1 and 2 fair value
measurements and separate disclosures about purchases, sales, issuances and settlements relating to Level 3 fair value measurements. The ASU also clarifies existing disclosure requirements regarding inputs and valuation techniques, as well as the
level of disaggregation for each class of assets and liabilities for which separate fair value measurements should be disclosed. We adopted ASU 2010-06 at the beginning of fiscal 2010. The adoption of this ASU did not have a material impact on our
condensed consolidated financial statements.

Critical Accounting Estimates and Assumptions

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make judgments,
estimates and assumptions in the preparation of our condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates. We believe there have been no significant changes in our critical accounting
policies discussed in our Annual Report on Form 10-K for the year ended December 31, 2009.

Results of Operations

Product sales were $20.7 million and $38.7 million for the three- and six-months ended June 30, 2010, respectively, compared to $22.0
million and $37.0 million for the corresponding periods in 2009. Product sales to China were $20.2 million and $37.3 million, or 98% and 96% of sales, for the three- and six-month periods ended June 30, 2010, respectively, compared to $21.2
million and $35.8 million, or 97% of sales, for the corresponding periods in 2009. Our overall revenue growth for the six-month period ended June 30, 2010, compared to the corresponding period in 2009, was attributable to an increase in the
quantity of ZADAXIN sold primarily due to further market penetration in China. Our decrease in revenue for the three-month period ended June 30, 2010, compared to the corresponding period in 2009, was due to increased demand for ZADAXIN in
2009, which we believe was a result of the H1N1 flu virus. All product sales in each period were derived from sales of ZADAXIN. For the three-month period ended June 30, 2010, sales to two importing agents in China accounted for approximately
75% and 23% of our product sales. For the three-month period ended June 30, 2009, sales to three importing agents in China accounted for approximately 66% and 31% of our product sales. For the six-month period ended June 30, 2010, sales to
three importing agents in China accounted for approximately 67%, 14% and 12% of our product sales. For the six-month period ended June 30, 2009, sales to two importing agents in China accounted for approximately 66% and 31% of our product
sales. The two largest customers were the same importing agents in each of these periods.

Gross margin on product sales was
82.9% and 83.7% for the three- and six-month periods ended June 30, 2010, respectively, compared to 84.4% and 83.6% for the three- and six-month periods ended June 30, 2009. The decrease in gross margin for the three-month period ended
June 30, 2010, compared to the three-month period ended June 30, 2009, was attributable to higher per vial fixed production costs resulting from lower production volume in 2010 compared to 2009. We estimate that our future cost of product
sales will increase for the year ending December 31, 2010 in relation to an expected increase in the level of ZADAXIN sales. We expect cost of product sales and gross margins to fluctuate from period to period depending upon the level of sales
and price of ZADAXIN, the absorption of product-related fixed costs, currency exchange fluctuations, and any charges associated with excess or expiring finished product inventory.

Research and development (R&D) expenses were $2.4 million and $5.1 million for the three- and six-month periods ended
June 30, 2010, respectively, compared to $3.6 million and $8.4 million for the three- and six-month periods ended June 30, 2009, respectively. The decreases in the three- and six-month periods were primarily related to the timing of
clinical trial-related expenses, including the completion of enrollment of patients in our phase 2 clinical trial of SCV-07 for the delay to onset of severe oral mucositis in the first quarter of 2010 and the discontinuation of the RP101 clinical
trial for the treatment of pancreatic cancer last year. These decreases were partially offset by increased expenses related to our SCV-07 phase 2 clinical trial for the treatment of HCV.

The major components of R&D expenses include salaries and other personnel-related expenses, including associated stock-based
compensation, facility-related expenses, depreciation of facilities and equipment, license-related fees, services performed by clinical research organizations and research institutions and other outside service providers, and the sharing of certain
costs for the development of ZADAXIN by our partner, Sigma-Tau.

The initiation and continuation of our current clinical
development programs has had and is expected to continue to have a significant effect on our research and development expenses. Actual costs incurred in future periods will vary depending in particular upon timeline and design for further clinical
trials and final decisions regarding the timing and expense-sharing arrangements for these trials, though we expect our research and development expenses to increase for the remainder of the year in preparation for our SCV-07 phase 2b trial in oral
mucositis which we plan to initiate in late 2010 or early 2011. An expansion or significant extension of our clinical development programs may require us to seek additional capital resources.

We are evaluating opportunities to acquire or in-license the marketing rights to proprietary products primarily in China, which may result in increased research and development expenses due to
license fee payments or other expenses related to in-licensing and development of new products in the future.

Sales and
marketing expenses were $5.6 million and $10.6 million for the three- and six-month periods ended June 30, 2010, respectively, compared to $4.8 million and $8.9 million for the three- and six-month periods ended June 30, 2009,
respectively. The increase in sales and marketing expenses for the three-and six-month periods was primarily due to increased conference, travel, and compensation expenses associated with our sales efforts for ZADAXIN in the 2010 periods. We expect
sales and marketing expenses to increase for the remainder of 2010 compared to 2009, related to our expanding sales efforts associated with the growth of our international business, primarily in China.

General and administrative expenses were $3.4 million and $6.6 million for the three- and six-month periods ended June 30, 2010,
respectively, compared to $2.7 million and $5.9 million for the three- and six-month periods ended June 30, 2009. The increase in general and administrative expenses for the three- and six-month periods in 2010 related to business development
efforts for China and costs associated with ongoing corporate, legal and intellectual property activities. We expect our general and administrative expenses for the remainder of 2010 will be comparable to 2009, though the timing of expenses may
fluctuate from quarter to quarter.

Other income (expense), net was other expense of $0.1 million for the three- and six-month
periods ended June 30, 2010, respectively, compared to other income of $46,000 and $23,000 for the three- and six-month periods ended June 30, 2009. The increases in expense in the 2010 periods compared to 2009 were due to foreign exchange
losses associated with our value added tax receivable balance denominated in euros.

Provision for income tax was $0.2 million
and $0.4 million for the three- and six-month periods ended June 30, 2010, respectively, compared to $0.2 million and $0.3 million for the three- and six-month periods ended June 30, 2009, and related to our foreign operations in China.
The increases in the 2010 periods compared to 2009 were due to increased operating activities in China and an increased statutory tax rate in China from 20% in 2009 to 22% in 2010. We expect these increases to continue for the remainder of 2010.

Liquidity and Capital Resources

Days sales outstanding in accounts receivable, using the average receivables method, were 95 and 97 days as of June 30, 2010
and 2009, respectively. The majority of our sales are to importers in China where our accounts receivable collections have standard credit terms ranging from 90 to 180 days.

At June 30, 2010 and December 31, 2009, we had $43.3 million and $31.8 million, respectively, in cash and investments. Net cash
provided by (used in) operating activities was $10.9 million and ($5.8) million, for the six months ended June 30, 2010 and 2009, respectively. Net cash provided by (used in) operating activities for the six months ended June 30, 2010 and
2009, primarily reflected the net income for the periods, adjusted for non-cash items such as stock-based compensation expense, depreciation and amortization expense and changes in operating assets and liabilities. For the six months ended
June 30, 2010, such changes included a $1.2 million decrease in accounts payable and a decrease in inventory levels by $1.3 million to fulfill sales demands.

Net cash used in investing activities was $6.0 million and $0.1 million for the six months ended June 30, 2010 and 2009,
respectively. Cash used in investing activities was primarily related to the purchase of available-for-sale investments, net of proceeds from the sale or maturity of investments.

Net cash provided by financing activities of $1.1 million and $0.1 million for the six months ended June 30, 2010 and 2009,
respectively, consisted of proceeds from the exercise of stock options made under our stock award plans.

In November 2008,
SciClone and its subsidiaries, SciClone Pharmaceuticals International Ltd. (SPIL) and SciClone Pharmaceuticals International China Holding Ltd. (SPIL China) as borrowers, entered into a loan and security agreement and an
unconditional guaranty and security agreement with Silicon Valley Bank (the Credit Facility). The Credit Facility is a line-of-credit that permits borrowing up to $6 million for a term of 36 months, subject to certain sublimits,
including $2.5 million for letters of credit. The Credit Facility is secured by a first priority secured interest in all of our assets, other than intellectual property. The Credit Facility also requires us to obtain a credit insurance policy
insuring certain foreign account receivable assets. SciClone Pharmaceuticals, Inc., as the parent of SPIL and SPIL China, is the guarantor of the Credit Facility. The Credit Facility expires in November 2011, and upon termination all amounts
borrowed must be repaid in full. As of June 30, 2010, there were no outstanding borrowings under the Credit Facility.

The Credit Facility bears interest at the banks prime rate plus 1.75% on outstanding balances. We are required to meet certain
financial covenants, including minimum consolidated revenue, and minimum consolidated earnings before interest and income tax, as defined, and since November 14, 2009, have been subject to certain minimum fees and interest payments. We

are also required to meet certain operating covenants that limit our ability to incur liabilities, create liens, make capital expenditures, pay dividends or distributions, make investments, and
dispose of assets and to carry credit insurance.

We have received a limited waiver to the Credit Facility to waive certain
minimum fees and interest payments, and to waive the requirement to maintain a credit insurance policy. We are currently in compliance with the Credit Facility after giving effect to the limited waiver.

In May 2009, we filed a shelf registration statement on Form S-3 with the SEC under which we may offer and sell up to $50.0 million of
our securities, (plus an additional $10.0 million that we could sell under an immediately effective related registration statement), assuming we continue to meet the SECs eligibility requirements for primary offerings on Form S-3.

We believe that our existing cash and investments and ongoing revenue generating business operations will be sufficient to support our
current operating plan for at least the next 12 months. We have no current commitments to offer and sell any securities that may be offered or sold pursuant to our registration statement. To the extent that we raise additional capital by issuing
equity securities, our stockholders may experience dilution. Debt financing, if available, may subject us to restrictive covenants and significant interest costs. To the extent that we raise additional funds through collaboration and licensing
arrangements, we would be required to relinquish some rights to our technologies, product candidates or marketing territories. Additional financing or collaboration and licensing arrangements may not be available when needed either at all or, on
favorable terms.

We intend to continue to explore alternatives for financing to provide additional flexibility in managing
our operations, in-licensing or acquiring new products, particularly in China, and funding our clinical trials. The unavailability or the inopportune timing of any financing could prevent or delay our long-term product development and
commercialization programs, either of which could hurt our business. We cannot assure you that funds from financings, if any, will be sufficient to conduct and complete further clinical trials or to acquire or in-license additional products. The
need, timing and amount of any such financing would depend upon numerous factors, including the level of ZADAXIN sales, the timing and amount of manufacturing costs related to ZADAXIN, the availability of complementary products, technologies and
businesses, the initiation and continuation of preclinical and clinical trials and testing, the timing of regulatory approvals, developments in relationships with existing or future collaborative parties, the status of competitive products, and
various alternatives for financing. We have not determined the timing or structure of any transaction.

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements.



|Item 3. | Quantitative and Qualitative Disclosures About Market Risk
|------- | ----------------------------------------------------------

The primary objective of our investment activities is to preserve principal while at the same time maximizing yields without
significantly increasing risk. To achieve this objective, we invest in money market funds, certificates of deposit, term deposits, U.S. Treasury, or government agency notes. All of our investments mature within one year from date of purchase except
for our Italian state bonds which mature in 2013. Our investment securities may be subject to interest rate risk and could decrease in value if market interest rates rise. To minimize this risk, we primarily hold securities that are short-term in
duration and maintain an average maturity of less than one year. We believe that our exposure to interest rate risk is not significant and a 1% movement in market interest rates would not have a significant impact to the total value of our
investment portfolio at June 30, 2010.

We do not hold any derivative financial instruments for speculation or trading
purposes. Substantially all our sales and most of our manufacturing costs to date have been in U.S. dollars. However, some of our purchases with contract manufacturers are denominated in euros and costs of our marketing efforts in China are paid in
local currency. In addition, we have certain cash balances and other assets denominated in euros. As a result, we are exposed to foreign currency rate fluctuations, and we do not hedge against the risk associated with such fluctuations.
Consequently, changes in exchange rates could result in material exchange losses and could unpredictably, materially and adversely affect our operating results and stock price. Such losses have not been significant to date.

Evaluation of
Disclosure Controls and Procedures

Under the supervision and with the participation of our management, including our Chief
Executive Officer (CEO) and Chief Financial Officer (CFO), we evaluated the effectiveness of our disclosure controls and procedures, as such term is defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of
1934, as amended. Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures were effective as of the end of the period covered by this quarterly report.

Changes in Internal Controls

There has been no change in the Companys internal control over financial reporting (as such term is defined in Rules 13a-15(f) and
15d-15(f) under the Securities Act of 1934, as amended) that was identified in connection with the evaluation thereof that occurred during the second quarter of 2010 that has materially affected, or is reasonably likely to materially affect, the
Companys internal control over financial reporting.

Limitations of the Effectiveness of Internal Controls

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of
the internal control system are met. Because of inherent limitations in any control systems, no evaluation of controls can provide absolute assurance that all control issues, if any, within a company have been detected. We are continuously seeking
to improve the efficiency and effectiveness of our operations and of our internal controls. This results in refinements to processes throughout our organization.

Item 1A. Risk Factors

Our risk factors are set forth below in their entirety. The list is not exhaustive and you should carefully consider these risks and
uncertainties before investing in our common stock. We have marked with an asterisk (*) those risk factors below that reflect substantive changes from the risk factors included in our Annual Report on Form 10-K filed with the Securities and
Exchange Commission on March 16, 2010.

Our stock price may be volatile, and an investment in our stock could
suffer a decline in value. *

We have a history of operating losses and an accumulated deficit. Although we reported net
income of $11.9 million for the year ended December 31, 2009 and $9.7 million for the six months ended June 30, 2010, we have experienced significant operating losses in the past, and as of June 30, 2010, we had an accumulated deficit
of approximately $155.2 million. If our operating expenses were to increase or if we were not able to increase or sustain revenue, we may not achieve profitability over the next 12 months.

The market price of our common stock has experienced, and may continue to experience, substantial volatility due to many factors, some of
which we have no control over, including:

Our revenue is dependent on our sale of ZADAXIN in China, and if we experience difficulties in our foreign sales efforts, our
operating results and financial condition will be harmed. *

Our product revenue is highly dependent on the sale of
ZADAXIN in China. If we experience difficulties in our foreign sales efforts in China, our business will suffer and our operating results and financial condition will be harmed. For the six months ended June 30, 2010 and 2009, approximately 96%
and 97%, respectively, of our ZADAXIN sales were to customers in China. Sales of ZADAXIN in China may be limited due to the low average personal income, lack of patient cost reimbursement, poorly developed infrastructure and competition from other
products, including generics. ZADAXIN sales growth in recent years has benefited from the rapidly growing Chinese economy and growing personal disposable income. Sales of ZADAXIN in China could be adversely affected by a slowing or downturn of the
Chinese economy.

In China, ZADAXIN is approved only for the treatment of hepatitis B virus (HBV) and as a vaccine
adjuvant. We face competition from pharmaceutical companies who are aggressively marketing competing products for the treatment of HBV and other indications where we believe ZADAXIN may be used on an off-label basis. In addition, several local
companies are selling lower-priced, locally manufactured generic thymosin, which is a competitive product and is selling in substantial and increasing quantities. While generic products outsell ZADAXIN in unit volumes, we have been able to maintain
an advantage through the reputation of our imported, branded product. We expect such competition to continue and there could be a negative impact on the price and the volume of ZADAXIN sold in China, which would harm our business. Our efforts to
in-license or acquire other pharmaceutical products for marketing in China and other markets may be unsuccessful or even if successful may not have a meaningful effect on our dependence on ZADAXIN sales in those markets.

In November 2009, thymosin alpha 1, the generic chemical name for our pharmaceutical product ZADAXIN, was included as a Category B
product in the National Reimbursed Drug List and pricing for ZADAXIN on the National Reimbursed Drug List is still being reviewed by the authorities. China regulates pharmaceutical prices and pharmaceutical importation. These regulations may reduce
prices for ZADAXIN to levels significantly below those that would prevail in an unregulated market, limit the volume of product which may be imported and sold or place high import duties on the product, any of which may limit the growth of our
revenues or cause them to decline. We believe that the Chinese government is increasing its efforts to reduce overall health care costs, including through pricing controls. Individual provinces in China and, in some cases, individual hospitals can
and have established pricing requirements for a product to be included on formulary lists. In some cases, these prices have been lower than our distributors have been selling ZADAXIN, in which case we have been removed from formulary lists, which
consequently has reduced sales to certain hospitals and could adversely affect our future sales. The Chinese national and provincial governments regulate product pricing and the maximum prices for ZADAXIN at the provincial level over the next
several years, and potentially at the national level. The process and timing for this is unpredictable. In addition, we are aware that ZADAXIN may be used on an off-label basis, and the Chinese governments pricing, reimbursement or other
actions might reduce such uses. We are working on these regulatory processes as well as on potential changes in our business model depending on potential outcomes. We believe we will be able to successfully manage our business in China through this
process, however maximum prices could be set at some time in the future which could adversely affect our results or require substantial changes in our business model which may be difficult to implement.

We have received regulatory approvals to import and market ZADAXIN in China and to manufacture ZADAXIN and export the product from Italy.
In order to continue our sales to China, we need to maintain these approvals. Our license to import ZADAXIN into China needs to be renewed every five years and the next renewal is required in 2013. Although we were successful in obtaining a renewal
in 2008, there is no assurance that we will receive renewals in the future when applied for or that the renewals will not be conditioned or limited in ways that limit our ability to sell ZADAXIN in China. Further, our licenses to manufacture and
export ZADAXIN from Italy are dependent upon our continuing compliance with regulations in Italy. Our business would be adversely affected if we are not able to maintain these approvals. In order to sell ZADAXIN to the licensed importers in China,
our manufacturers must 1) be approved by the Italian Ministry of Health (AIFA) and 2) be accepted by the State Food and Drug Administration of China (SFDA), the Chinese equivalent to the United States Food and Drug
Administration (FDA), and we must obtain an Imported Drug License from the SFDA permitting the importation of ZADAXIN into China. The license must be renewed every five years, and if we change manufacturers, these changes must 1)



20

##### Table of Contents

be approved by the AIFA in Italy and 2) be accepted by the SFDA. When we change manufacturers we must obtain a new approval. We are currently in the process of changing manufacturer and if we are
not successful in obtaining the necessary approval in a timely manner, our business would be adversely affected. The SFDA, the FDA, AIFA and other regulatory agencies may, and have, changed their internal administrative rules in ways that may delay
or complicate the regulatory process. Those changes are not always disclosed or known to us and we may experience unexpected delays or additional costs as a result of such changes.

Our ZADAXIN sales and operations in other parts of China and the world are subject to a number of risks and increasing regulations,
including difficulties and delays in obtaining registrations, renewals of registrations, permits, pricing approvals and reimbursement, increasing regulation of product promotion and selling practices, unexpected changes in regulatory requirements
and political instability. In addition, during the second quarter of 2009 we experienced a strong upsurge in ZADAXIN sales which we believe was attributable both to the increasing penetration of ZADAXIN within the Chinese market, as well as concerns
in China from the H1N1 flu virus. Although we believe that ZADAXIN sales have returned to levels more consistent with our established business, if distributors and hospitals that purchase ZADAXIN stockpile more ZADAXIN than needed for current use,
our sales of ZADAXIN may suffer as distributors and hospitals use ZADAXIN already in their inventory before purchasing additional product from us. This could lead to uneven future revenue results for ZADAXIN and in turn materially impact our cash
flow and business condition.

We experience other issues with managing foreign sales operations including long payment cycles,
potential difficulties in accounts receivable collection and, especially from significant customers, fluctuations in the timing and amount of orders and the adverse effect of any of these issues on our business could be increased due to the
concentration of our business with a small number of distributors. Problems with collections from, or sales to, any one of those distributors could materially adversely affect our results. Operations in foreign countries including China also expose
us to risks relating to difficulties in enforcing our proprietary rights, currency fluctuations and adverse or deteriorating economic conditions. If we experience problems with obtaining registrations, complying with reimbursement rules or
compliance with foreign country or applicable U.S. laws, adverse or mixed outcome of clinical studies anywhere in the world, or if we experience difficulties in payments or intellectual property matters in foreign jurisdictions, or if significant
political, economic or regulatory changes occur, our results could be adversely affected. Moreover, our operations throughout the world including China are potentially subject to the laws and regulations of the United States including the Foreign
Corrupt Practices Act, in addition to the laws and regulations of the local countries. Regulation in China of the activities in the pharmaceutical industry has increased and may continue to undergo significant and unanticipated changes. A number of
companies have faced significant expenses or fines as a result of the increasing regulation of, and enforcement activity regarding, the pharmaceutical industry. We recently received notices of investigations by US government agencies that relate to
our operations in China. If we fail to comply with regulations or to carry out controls on our Chinese or other foreign operations in a manner that satisfies all applicable laws, our business would be harmed.

The Chinese government has been engaged in an extensive stimulus program in China over the past year. We believe that the Chinese
government is reducing these stimulus programs. We believe these programs have had broad effects across the Chinese economy, and the reduction or withdrawal of these programs could adversely affect spending in numerous ways, including reduction of
spending on pharmaceutical products including ZADAXIN.

Our sales of ZADAXIN may fluctuate due to seasonality of product
orders and sales in any quarter may not be indicative of future sales.

Our sales for the quarter ended June 30, 2009
were greatly affected by the demand in China for ZADAXIN which we believe was in connection with Influenza A (H1N1). Similarly, our sales for the quarter ended June 30, 2003 were greatly affected by the demand in China for ZADAXIN in connection
with the treatment of Severe Acute Respiratory Syndrome (SARS). To date, SARS has not re-emerged, like influenza, as a seasonal public health problem. However, it is not possible to predict what effect, if any, H1N1, SARS, or similar
epidemics would have on future sales of ZADAXIN, if they were to emerge. Although we do not market ZADAXIN for use in treating epidemic diseases such as Influenza A (H1N1) or SARS, if ZADAXIN is purchased in connection with outbreaks of seasonal
viral contagions, product sales could become more concentrated in certain quarters of the calendar year, quarterly sales levels could fluctuate and sales in any quarter may not be indicative of sales in future periods.

We may lose market share or otherwise fail to compete effectively in the intensely competitive pharmaceutical industry.

Competition in the pharmaceutical industry in China is intense, and we expect that competition will increase. Our success
depends on our ability to compete in this industry, but we cannot assure you that we will be able to successfully compete with our competitors. Increased competitive pressure could lead to intensified price-based competition resulting in lower
prices and margins, which would hurt our operating results. We cannot assure you that we will compete successfully against our competitors or that our competitors, or potential competitors, will not develop drugs or other treatments for our targeted
indications that will be superior to ours.

##### Table of Contents

We depend on sales in China, and global conditions could negatively affect our operating
results or limit our ability to expand our operations outside of China. Changes in Chinas political, social and economic environment may affect our financial performance.

A large majority of our sales are in China. Heightened tensions resulting from the current geopolitical conditions in the Middle East,
North Korea and elsewhere could worsen, causing disruptions in foreign trade, which would harm our sales. In particular, our commercial product is manufactured in Europe and distributed by us from our operations in Hong Kong. Any disruption of our
supply and distribution activities due to geopolitical conditions could decrease our sales and harm our operating results.

With respect to China, our financial performance may be affected by changes in Chinas political, social and economic environment.
The role of the Chinese central and local governments in the Chinese economy is significant. Chinese policies toward economic liberalization, and laws and policies affecting foreign companies, currency exchange rates and other matters could change,
resulting in greater restrictions on our ability to do business in China. Any imposition of surcharges or any increase in Chinese tax rates could hurt our operating results. The Chinese government could revoke, terminate or suspend our license for
national security and similar reasons without compensation to us. If the government of China were to take any of these actions, we would be prevented from conducting all or part of our business. Any failure on our part to comply with governmental
regulations could result in the loss of our ability to market our products in China.

Because of Chinas tiered method
of importing and distributing finished pharmaceutical products, our quarterly results may vary substantially from one period to the next. *

China uses a tiered method to import and distribute finished pharmaceutical products. At each port of entry, and prior to moving the
product forward to the distributors, government-licensed importing agents must process and evaluate each shipment to determine whether such shipment satisfies Chinas quality assurance requirements. In order to efficiently manage this process,
the importing agents typically place large, and therefore relatively few, orders within an annual period. Therefore, our sales to an importing agent can vary substantially from quarter to quarter depending on the size and timing of the orders, which
has in the past and may in the future cause our quarterly results to fluctuate. We rely on a limited number of importers, in any given quarter, to supply substantially all of our product in China. Because we use a small number of importing agents in
China, our receivables from any one importing agent are material, and if we were unable to collect receivables from any importer, our business and cash-flow would be adversely affected.

The existence of counterfeit pharmaceutical products in Chinas pharmaceutical retail market may damage our brand and reputation
and have a material adverse effect on our business, financial condition, results of operations and prospects. *

Certain
medicine products distributed or sold in Chinas pharmaceutical retail market, including those appearing to be our products, may be counterfeit. Counterfeit products are products sold under the same or very similar brand names and/or having a
similar appearance to genuine products. Counterfeit products, including counterfeit pharmaceutical products, are a significant problem in China. Such products divert sales from genuine products, often are of lower cost, often are of lower quality
(having different ingredients or formulations, for example), and have the potential to damage the reputation for quality and effectiveness of the genuine product. The counterfeit pharmaceutical product regulation control and enforcement system in
China is not able to completely eliminate production and sale of counterfeit pharmaceutical products. Any sale of counterfeit products resulting in adverse side effects to consumers may subject us to negative publicity and expenses. It could have a
material adverse effect on our business, financial condition, results of operations and prospects.

We may be subject to
currency exchange rate fluctuations, which could adversely affect our financial performance.

Substantially all of our
product sales are denominated in U.S. dollars. Fluctuation in the U.S. dollar exchange rate with local currency directly affects the customers cost for our product. In particular, a stronger U.S. dollar vis-à-vis the local currency
would tend to have an adverse effect on sales and potentially on collection of accounts receivable. China currently maintains the value of the renminbi in a narrow currency trading band that may or may not fluctuate based upon government policy.
Depending on market conditions and the state of the Chinese economy, it is possible that China could make future adjustments, including moving to a managed float system, with opportunistic interventions. This reserve diversification may negatively
impact the United States dollar and U.S. interest rates. A trend to a stronger U.S. dollar would erode margins earned by our Chinese importers and prompt them to ask us to lower our prices. We are subject to currency exchange rate fluctuations as a
result of expenses incurred by our foreign operations. In particular, one of our supply arrangements under which we purchase finished products is denominated in euros and costs of our operations in China are paid in local currency. Consequently,
changes in exchange rates could unpredictably and adversely affect our operating results and could result in exchange losses. To date, we have not hedged against the risks associated with fluctuations in exchange rates and, therefore, exchange rate
fluctuations could have a material adverse impact on our future operating results and stock price.

Our business strategy is dependent on our ability to in-license or otherwise acquire the
rights to develop and commercialize products, particularly in China. If we fail to acquire such rights or are unsuccessful in our efforts to develop such products and obtain regulatory approval to market and successfully commercialize them, our
business will suffer.

All of our products, including ZADAXIN, the only one for which we have sales revenue, have been
in-licensed by us. We do not conduct product discovery and typically have in-licensed our products from third parties who have discovered the products and conducted at least some pre-clinical research on them. We are particularly focused on
in-licensing products for the China market and the competition for attractive products to in-license is intense, and we cannot assure you that we will be able to in-license products in the future on acceptable terms, if at all. In addition, we face
the risks of developing the in-licensed products and the risks and uncertainties of conducting clinical trials and seeking regulatory approval to market the in-licensed products, all of which require years of effort and the commitment of significant
financial resources. Our ability to grow our business requires the development and commercialization of additional products. If we are unable to in-license or acquire products on acceptable terms and successfully develop and commercialize them, our
business could be harmed.

We may engage in acquisitions and must successfully integrate any acquired products or companies
in order to avoid a material disruption to our business and material adverse effects to our financial results.

We may
engage in one or more acquisitions of products or companies. Acquisitions involve numerous risks, including the following:



| |  |  | difficulties and costs in integrating the operations, technologies, products and personnel of the acquired businesses;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | inadequate internal control procedures and disclosure controls to comply with the requirements of Section 404 of the Sarbanes-Oxley Act of 2002,
or poor integration of a target companys or businesses procedures and controls;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | diversion of managements attention from normal daily operations of the business;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | potential difficulties in completing projects associated with in-process research and development;
| | - |  | --------------------------------------------------------------------------------------------------



| |  |  | difficulties in entering markets in which we have no or limited direct prior experience and where competitors in such markets have stronger market
positions;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | insufficient net revenue to offset increased expenses associated with acquisitions;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | potential failure to achieve commercial expectations;
| | - |  | -----------------------------------------------------



| |  |  | potential loss of key employees of the acquired companies; and
| | - |  | --------------------------------------------------------------



| |  |  | difficulty in forecasting revenues and margins.
| | - |  | -----------------------------------------------

Acquisitions may also cause us to:



| |  |  | issue common stock that would dilute our current shareholders percentage ownership;
| | - |  | ------------------------------------------------------------------------------------



| |  |  | assume liabilities, some of which may be unknown at the time of such acquisitions;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | record goodwill and intangible assets that will be subject to impairment testing and potential periodic impairment charges;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | incur amortization expenses related to certain intangible assets;
| | - |  | -----------------------------------------------------------------



| |  |  | incur large and immediate write-offs of in-process research and development costs; or
| | - |  | -------------------------------------------------------------------------------------



| |  |  | become subject to litigation.
| | - |  | -----------------------------

Mergers and acquisitions of pharmaceutical companies inherently entail risk, and no assurance can be given that any future acquisitions
will be successful or will not adversely affect our business, operating results, or financial condition. Failure to manage and successfully integrate acquisitions could harm our business and operating results in a material way. Even when an acquired
company has already developed and marketed products, there can be no assurance of the continued prospects or success of such products or that pre-acquisition due diligence will have identified all possible issues that might arise with respect to
such products.

We may not be able to successfully develop or commercialize our products. *

While we have sales of ZADAXIN (thymalfasin or thymalfasin alpha 1) in certain markets, regulatory approval does not exist at
this time for ZADAXIN for the key markets of the United States, Europe (outside of Italy) and Japan and, in this respect ZADAXIN is still being developed. In 2006, we acquired the rights to distribute DC Bead in China, but we must



23



---

##### Table of Contents

receive regulatory approval before we can commercialize this product. We previously believed that regulatory approval for DC Bead in China would be forthcoming in 2009. However, the SFDA required
us to conduct a local trial in China to supplement data already obtained from a previous DC Bead study. This study is underway and if the trial results are positive, we expect to receive regulatory approval for DC Bead in 2011. Our other potential
products presently are SCV-07 and ondansetron RapidFilm and each of them is in an earlier stage of development than ZADAXIN. Clinical trials outcomes are uncertain. For example, in October 2009, we halted our phase 2 trial of RP101 and we have no
plans to proceed with further development of RP101 at this time. We may consider and undertake various strategies to expand our portfolio of potential products, including acquiring product candidate rights through licenses or other relationships, or
through other strategic relationships including acquisitions of other companies that may have proprietary rights to other development candidates or the capability to discover new drug candidates. Such transactions could require a substantial amount
of our financial resources, or, if equity is involved, may result in substantial dilution to current stockholders. Strategic transactions also require substantial management time and effort and are subject to various risks that could adversely
affect us or our financial results.

To fully develop our products, substantial resources are required for extensive research,
development, pre-clinical testing, clinical trials, and manufacturing scale-up and regulatory approval prior to the potential products being ready for sale. We cannot assure that our efforts will produce commercially viable products. We face
significant technological risks inherent in developing these products. We may also abandon some or all of our proposed products before they become commercially viable. For DC Bead, we are obligated to pay half of the costs in our efforts to obtain
regulatory approval in China and, due to recent events, the total amount of costs for DC Bead will increase. For ondansetron RapidFilm, we are obligated to make a milestone payment upon regulatory approval. If any of our products, even if developed
and approved, cannot be successfully commercialized in a timely manner, our business will be harmed and the price of our stock may decline.

We have not yet sold any product other than ZADAXIN and our sales have been primarily to a single country, China. Our future revenue
growth depends to a great extent on increased market acceptance and commercialization of ZADAXIN in additional countries, as well as our ability to increase sales in China. If we fail to successfully market ZADAXIN or if we cannot commercialize this
drug in the United States and other additional markets, our revenue and operating results will be limited. If unexpected and serious adverse events are reported, or if expected efficacy results are not achieved, it would have a material adverse
effect on our business. Our future revenue will also depend in part on our ability to develop other commercially viable and accepted products, such as DC Bead, ondansetron RapidFilm, and SCV-07. Market acceptance of our products will depend on many
factors, including our ability to convince prospective customers to use our products as an alternative to other treatments and therapies and to convince prospective strategic partners to market our products effectively and to manufacture our
products in sufficient quantities with acceptable quality and at an acceptable cost. In addition, doctors must opt to use treatments involving our products. If doctors elect to use a different course of treatment, demand for our drug products would
be reduced. Failure to do any of the above will lead to an unfavorable outcome on the results of our operations.

We cannot
predict the safety profile of the use of thymalfasin, DC Bead, ondansetron RapidFilm or SCV-07 when used in combination with other drugs.

Many of our trials involve the use of thymalfasin in combination with other drugs. SCV-07 may be developed to be used in combination with
other drugs. Some of these drugs, particularly pegylated interferon alpha, ribavirin, non-pegylated interferon alpha, dacarbazine and gemcitabine are known to cause adverse patient reactions. We cannot predict how thymalfasin, DC Bead, ondansetron
RapidFilm or SCV-07 will work with other drugs, including causing possible adverse side effects not directly attributable to the other drugs that could compromise the safety profile of thymalfasin, DC Bead, ondansetron RapidFilm or SCV-07 when used
in certain combination therapies.

Final results from our proposed or ongoing clinical trials for thymalfasin, SCV-07,
ondansetron RapidFilm, and DC Bead may differ materially from interim or pre-clinical trial results. These clinical trials could be affected by the future actions of our partners, unexpected delays, unanticipated patient drop-out rates or adverse
side effects, future actions by the SFDA or the FDA or equivalent regulatory authorities in Europe or other countries or additional expenses.

Our ability to achieve and sustain operating profitability depends in large part on our ability to commence, execute and complete
clinical programs and obtain additional regulatory approvals for ZADAXIN and other drug candidates.

Clinical trials are
inherently risky and may reveal that our product candidates are ineffective or have unanticipated side effects and/or drug interactions that may significantly decrease the likelihood of regulatory approval. In October 2009, we announced the
discontinuation of our phase 2 clinical trial evaluating RP101, a nucleoside analog known as BVdU, for the treatment of late-stage pancreatic cancer. This decision followed the recommendation of the trials Data Safety Monitoring Committee
(DSMC) based upon the data reviewed and we have no plans to proceed with further development of RP101 at this time. In addition, on November 5, 2008, we announced the top-line results from a large, randomized, phase 3 clinical trial
evaluating thymalfasin in combination with pegylated interferon alpha-2a (peg-IFN-2a) and ribavirin (RBV) as a treatment for patients with hepatitis C virus (HCV) who have not responded to prior therapy consisting
of peg-IFN and RBV alone (current standard of care). The thymalfasin treated group did not achieve statistical significance for the primary end point of sustained virological response (SVR) as assessed in the primary analysis population,
i.e. the intent-to-treat population. In the



24



---

##### Table of Contents

prospectively defined secondary population of patients who completed the full course of 48 weeks of treatment with thymalfasin in addition to peg-IFN-2a and RBV (Completer
Population), the primary endpoint was achieved with statistical significance. These results did not meet our expectations based upon prior clinical trials. Similarly, the results of our thymalfasin phase 2 melanoma clinical trial do not
necessarily predict future clinical or commercial success. Finally, the results of studies in DC Bead, ondansetron RapidFilm, SCV-07, including a phase 2a for HCV, pre-clinical and phase 1 trial results also do not predict clinical or commercial
success.

We may face numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent
commercialization of our product candidates including: our product candidate clinical trials may not prove statistical significance; negative or inconclusive clinical trial results may require us to conduct further testing or we may choose to
abandon projects that we had been expecting to complete; clinical trials may be halted due to safety reasons; patient drop-out rates in our clinical trial may be higher than anticipated; the FDA, its European equivalent EMEA or the SFDA may not
approve our products for commercialization or may require additional clinical trial data prior to approving our products; and/or our future expenses and ability to proceed with a trial may be dependent in part on finding a partner. Moreover, if the
outcome of any of these trials is unsuccessful, or even if successful, does not achieve commercially meaningful results, our business could be harmed.

If third-party reimbursement is not available or patients cannot otherwise pay for ZADAXIN, DC Bead, ondansetron RapidFilm, or SCV-07,
we may not be able to successfully market them. *

Significant uncertainty exists as to the reimbursement status of new
therapeutic products, such as ZADAXIN, and once commercialized, DC Bead, ondansetron RapidFilm and SCV-07. We cannot assure you that third-party insurance coverage and reimbursement will be available for therapeutic products we might develop.
Although ZADAXIN receives some limited reimbursement in certain provinces in China, we cannot assure you that we will be able to maintain existing reimbursements or increase third-party payments for ZADAXIN or obtain third-party payments for DC Bead
in China or ondansetron RapidFilm in China including Hong Kong and Macau, or Vietnam. The failure to obtain or maintain third-party reimbursement for our products would harm our business. Further, we cannot assure you that additional limitations
will not be imposed in the future in the United States or elsewhere on drug coverage and reimbursement due to proposed health care reforms. In many emerging markets where we have marketing rights to ZADAXIN, but where government resources and per
capita income may be so low that our products will be prohibitively expensive, we may not be able to market our products on economically favorable terms, if at all.

Efforts by governmental and third-party payers to contain or reduce health care costs or the announcement of legislative proposals or
reforms to implement government controls could cause us to reduce the prices at which we market our drugs, which would reduce our gross margins and may harm our business.

If we do not obtain regulatory approval for thymalfasin, SCV-07, ondansetron RapidFilm or DC Bead for the intended indications that we
are evaluating, our revenues will be limited and our operating results may be materially affected. *

Our ability to
execute on our business strategy is largely dependent on our ability to obtain regulatory approval for the use of thymalfasin in major markets, for the use of SCV-07 in major markets, excluding Russia, for the use of ondansetron RapidFilm in China
including Hong Kong and Macau, and Vietnam, and for the use of DC Bead in China. The regulatory approval processes in the United States, Europe and China are demanding and typically require 12 months or more in the United States and China and 18
months or more in Europe from the date of submission of an NDA. We have committed significant resources, including capital and time, to develop these products, and intend to continue to do so, including the initiation and execution of additional
clinical trials, with the goal of obtaining such approvals. If we do not obtain these approvals, we will be unable to achieve any revenue from these products in these major markets and our thymalfasin sales in other jurisdictions could decline.

We believed that regulatory approval for DC Bead would be forthcoming in 2009. However, the SFDA required us to conduct a
local trial in China to supplement data already obtained from a previous DC Bead study. The study is underway and if the trial results are positive, we expect to receive regulatory approval for DC Bead in 2011. However, we cannot give assurance that
such submission will be approved by the regulatory authorities. If additional clinical trials in China are required as part of the regulatory process, the regulatory submission for marketing approval could be delayed for a considerable period of
time, and there can be no assurance that the results of clinical trials would support a regulatory submission or that the regulatory authorities would approve the product to be commercialized and sold in China. To the extent that additional
information or clinical trials are required by the regulatory authorities, or we do not receive regulatory approval in China, our future sales potential in China could be harmed.

All new drugs, including our products, which have been developed or are under development, are subject to extensive and rigorous
regulation by the FDA, SFDA and similar regulatory agencies. These regulations govern, among other things, the development, testing, manufacturing, labeling, storage, pre-market approval, importation, advertising, promotion, sale and distribution of
our products. These regulations may change from time to time and new regulations may be adopted.

##### Table of Contents

Satisfaction of government regulations may take several years and the time needed to satisfy
them varies substantially based on the type, complexity and novelty of the pharmaceutical product. As a result, government regulation may cause us to delay the introduction of, or prevent us from marketing, our existing or potential products for a
considerable period of time and impose costly procedures upon our activities. Even if we obtain regulatory approval for our products, such approval may impose limitations on the indicated uses for which our products may be marketed. Further
unsatisfactory data resulting from clinical trials may also adversely affect our ability to market and sell thymalfasin in markets where it is approved for sale.

We rely on third parties who are our sole source suppliers for our clinical trial and commercial products and their inability to
deliver products that meet our quality-control standards could delay or harm one or more important areas of our business including our sales, clinical trials or the regulatory approval process.

We rely on third parties, who are subject to regulatory oversight, to supply our clinical and commercial products. For example,
Biocompatibles is the sole supplier of DC Bead, Applied Pharma Research S.A. (APR) is the sole supplier of ondansetron RapidFilm, and Solvay Peptides S.A. is our sole supplier of SCV-07. Any unanticipated deficiencies in these suppliers,
or the suppliers or our raw materials, and/or recall of the manufacturing lots or similar action regarding the pegylated interferon alpha, ribavirin or gemcitabine used in our clinical trials could delay the trials or detract from the integrity of
the trial data and its potential use in future regulatory filings. In addition, manufacturing interruptions or failure to comply with regulatory requirements by any of these suppliers could significantly delay clinical development of potential
products and reduce third-party or clinical researcher interest and support of proposed trials. These interruptions or failures could also impede commercialization of our products and impair our competitive position.

Further, any deficiencies or shortages in supply of our commercial products would adversely affect our ability to realize our sales
plans. For example, the manufacturing of the raw material and the processing to finished product of ZADAXIN is done in few batches in any given three-month period and any manufacturing errors have the potential to require a product recall. During
2006, we experienced failures and lower yields on production runs from our sole supplier of bulk active pharmaceutical ingredient (API) product for the manufacture of ZADAXIN for our current markets, including China. During 2009, we
experienced quality-control problems with a component of our ZADAXIN kit. Although we are taking steps to ensure that such problems do not continue, there is no assurance that we will either be successful in doing so with our current supplier or be
able to timely and cost-effectively qualify a new supplier for this component. Manufacturing interruptions or failure or delay of product to meet quality assurance specifications could adversely affect shipments and recognition of sales of ZADAXIN
in any period and impair our relationships with customers and our competitive position and may increase the cost of material produced.

We are in the process of registering new suppliers for ZADAXIN with regulatory agencies in markets where thymalfasin is approved for
sale, including China. This process, quality assurance and other steps could cause delays or interruptions of supply in certain other markets. In some countries, a manufacturing change may require additional regulatory approvals that may delay
thymalfasin marketing approvals in new markets. In addition, if sales of ZADAXIN were to increase dramatically, our third-party suppliers may not be able to supply ZADAXIN either quickly enough or at a commercially reasonable cost, which could limit
our ability to satisfy increased demand or could adversely affect the ability of these suppliers to provide products for our clinical trials. If any of our suppliers are unable to match our need for supply, either because of product defects,
inability to increase supply in the face of increased demand, or maintain financially viable businesses, our ability to affect our sales and protect our brand reputation would be materially impaired, thereby materially and adversely affecting our
sales and results of operations.

We rely on third parties for development of our products and the inability of any of
these parties to reliably, timely or cost-effectively provide us with their obligated services could materially harm the timing of bringing our products to market and accordingly adversely affect our business.

We rely on third parties, such as contract research organizations, medical institutions, clinical investigators, contract laboratories,
and collaborative partners in the conduct of clinical trials for our product candidates. If these parties, whom we do not control, do not successfully carry out their contractual duties or regulatory obligations or meet expected deadlines or choose
not to continue their relationship with us, if the third parties need to be replaced, or if the quality or accuracy of the data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for other
reasons, our pre-clinical or clinical activities may be extended, delayed, suspended or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize our product candidates.

Commercialization of some of our products depends on collaborations with others. If our collaborators are not successful, or if we are
unable to find future collaborators, we may not be able to properly develop and commercialize our products.

We depend in
part on our distributors and business partners to develop or promote our drugs, and if they are not successful in their efforts or fail to do so, our business will suffer. For example, Sigma-Tau is responsible for the development and marketing of
ZADAXIN in most of Europe. Biocompatibles is providing SciClone with the necessary supporting documents to obtain regulatory approval in China for DC Bead, APR is providing SciClone with the necessary supporting



26

##### Table of Contents

documents to obtain regulatory approval in China including Hong Kong and Macau, and Vietnam for ondansetron RapidFilm. We generally do not have control over the amount and timing of resources
that our business partners devote to our collaborative efforts, and some have not always performed as or when expected. If they do not perform their obligations as we expect, particularly obligations regarding clinical trials, our development
expenses would increase and the development or sale of our products could be limited or delayed, which could hurt our business and cause our stock price to decline. In addition, our relationships with these companies may not be successful. Disputes
may arise with our collaborators, including disputes over ownership rights to intellectual property, know-how or technologies developed with our collaborators. We may not be able to negotiate similar additional arrangements in the future to develop
and commercialize ZADAXIN or other products.

If we are unable to manage our key personnel, or are unable to attract and
retain additional, highly skilled and experienced personnel, our business will suffer.

We are highly dependent upon our
ability to attract and retain qualified personnel because of the specialized, scientific and worldwide nature of our business. Further, we are also dependent on our ability to appropriately staff these personnel in appropriate positions as our
business fluctuates. There is intense competition for qualified management, scientific, clinical, regulatory, and sales and marketing personnel in the pharmaceutical industry. There is significant turnover in the industry in China in
particular, and we have recently experienced significant turnover in our sales personnel. We may not be able to attract and retain the qualified personnel we need to grow and develop our business globally. Conversely, in the event that we need
to reduce the size of a particular aspect of our business, we are also dependent on our ability to make such adjustments while retaining suitably skilled personnel. Further, our efforts to in-license or acquire, develop and
commercialize product candidates for China require the addition of clinical and regulatory personnel and the capabilities to expand our sales and marketing operation. In addition, we assign numerous key responsibilities to a limited number of
individuals, and we would experience difficulty in finding immediate replacements for any of them were any one of them to choose to leave employment with us. If we were unable to attract and retain qualified personnel as needed or promptly replace
those employees who are critical to our product development and commercialization, the development and commercialization of our products would be adversely affected. At this time, we do not maintain key person life insurance for any of
our personnel.

We may need to obtain additional funding to support our long-term product development and commercialization
programs.

We believe our existing cash and investments and ongoing revenue generating business operations will be
sufficient to support our current operating plan for at least the next 12 months. However, our ability to achieve and sustain operating profitability is dependent on numerous factors including our ability to achieve our goal of increasing sales of
ZADAXIN, securing regulatory approval for DC Bead in China, and for ondansetron RapidFilm in China including Hong Kong and Macau, and Vietnam, the execution and successful completion of thymalfasin, SCV-07, and DC Bead clinical trials and securing
partnerships for those programs that lead to regulatory approvals in major pharmaceutical markets. We cannot assure you that such funds from operating activities will be sufficient, or that we will attain profitable operations in future periods. In
addition, we intend to develop other products and we may need additional funds in the future to support such development and to support future growth and achieve profitability. If we need to raise additional funds in the future and such funds are
not available on reasonable terms, if at all, our commercialization efforts may be impeded, our revenues may be limited and our operating results may suffer.

If we fail to protect our products, technologies and trade secrets, we may not be able to successfully use, manufacture, market or
sell our products, or we may fail to advance or maintain our competitive position, and we have limited intellectual property protection in China.

Our success depends significantly on our ability to obtain and maintain meaningful patent protection for our products and technologies
and to preserve our trade secrets. Our pending patent applications may not result in the issuance of patents in the future. Our patents or patent applications may not have priority over others applications. Our existing patents and additional
patents that may be issued, if any, may not provide a competitive advantage to us or may be invalidated or circumvented by our competitors. Others may independently develop similar products or design around patents issued or licensed to us. Patents
issued to, or patent applications filed by, other companies could harm our ability to use, manufacture, market or sell our products or maintain our competitive position with respect to our products. Although many of our patents relating to
thymalfasin have expired, including composition of matter patents, we have rights to other patents and patent applications relating to thymalfasin and thymalfasin analogues, including method of use patents with respect to the use of thymalfasin for
certain indications. Additionally, thymosin alpha 1 (thymalfasin), the chemical composition of thymalfasin, has received Orphan Drug designation in the United States for the treatment of stage IIb through stage IV melanoma. If other
parties develop generic forms of thymalfasin for other indications, including conducting clinical trials for such indications, our patents and other rights might not be sufficient to prohibit them from marketing and selling such generic forms of
thymalfasin. If other parties develop analogues or derivatives of thymalfasin, our patents and other rights might not be sufficient to prohibit them from marketing these analogues or derivatives.

Pharmaceutical products are either not patentable or have only recently become patentable in some of the countries in which we market or
may market thymalfasin. We do not have composition patent claims directed to the same form of



27

##### Table of Contents

thymalfasin currently marketed in China, our largest market, although we do have other type of patent claims, pending or issued, directed to other aspects of thymalfasin therapy. Other companies
market generic thymosin alpha 1 in China, sometimes in violation of our patent, trademark or other rights which, to date, we have defended by informing physicians and hospitals of the practice. Past enforcement of intellectual property rights in
many of these countries, including China in particular, has been limited or non-existent. Future enforcement of patents and proprietary rights in many other countries will likely be problematic or unpredictable. Moreover, the issuance of a patent in
one country does not assure the issuance of a similar patent in another country. Claim interpretation and infringement laws vary by nation, so the extent of any patent protection is uncertain and may vary in different jurisdictions.

If we are involved in intellectual property claims and litigation, the proceedings may divert our resources and subject us to
significant liability for damages, substantial litigation expense and the loss of our proprietary rights.

Our commercial
success depends in part on our not infringing valid, enforceable patents or proprietary rights of third parties, and not breaching any licenses that may relate to our technologies and products. In addition, we may not be aware of all patents or
patent applications that may impact our ability to make, use or sell any of our potential products. For example, U.S. patent applications may be kept confidential for 12 or more months while pending in the Patent and Trademark Office, and patent
applications filed in foreign countries are often first published nine months or more after filing. It is possible that we may unintentionally infringe these patents or other patents or proprietary rights of third parties. We may in the future
receive notices claiming infringement from third parties as well as invitations to take licenses under third-party patents. Any legal action against us or our collaborative partners claiming damages and seeking to enjoin commercial activities
relating to our products and processes affected by third-party rights may require us or our collaborative partners to obtain licenses in order to continue to manufacture or market the affected products and processes. Our efforts to defend against
any of these claims, regardless of merit, would require us to devote resources and attention that could have been directed to our operations and growth plans. In addition, these actions may subject us to potential liability for damages. We or our
collaborative partners may not prevail in a patent action and any license required under a patent may not be made available on commercially acceptable terms, or at all. Any conflicts resulting from the patent rights of others could significantly
reduce the coverage of our patents and limit our ability to obtain meaningful patent protection.

If other companies obtain
patents with conflicting claims, we may be required to obtain licenses to those patents or develop or obtain alternative technology to manufacture or market the affected products and processes. We may not be able to obtain any such licenses on
acceptable terms or at all. Any failure to obtain such licenses could delay or prevent us from pursuing the development or commercialization of our potential products. Our efforts to defend against any of these claims would require us to devote
resources and attention that could have been directed to our operations and growth plans.

We may need to initiate litigation,
which could be time-consuming and expensive, to enforce our proprietary rights or to determine the scope and validity of others rights. If litigation results, a court may find our patents or those of our licensors invalid or may find that we
have infringed on a competitors rights. If any of our competitors have filed patent applications in the United States which claim technology we also have invented, the Patent and Trademark Office may require us to participate in expensive
interference proceedings to determine who has the right to a patent for the technology. These actions may subject us to potential liability for damages. We or our collaborative partners may not prevail in a patent action and any license required
under a patent may not be made available on commercially acceptable terms, or at all.

Any government inquiry may be time
consuming and expensive and could result in injunctions, fines and penalties that may have a material adverse effect on our financial condition and results of operations. *

The Company has received a United States Securities and Exchange Commission (SEC) subpoena and a letter from the States
Department of Justice (DOJ) relating to investigations concerning the Companys sale, licensing and marketing of it products in foreign countries, including China. The SECs subpoena also seeks documents relating to other
matters, including certain financial and other disclosures. The DOJ letter refers to potential violations of the Foreign Corrupt Practices Act. We intend to cooperate with the SEC and DOJ in their investigations and our Board of Directors has
appointed a special committee of independent directors to oversee the Companys efforts in responding to and cooperating with these matters.

The period of time necessary to resolve the investigations is uncertain, and we cannot predict its outcome or whether we will face
additional government inquiries, investigations, litigation or other actions related to these or other matters. These or any other investigation could result in civil and criminal actions seeking, among other things, injunctions against the Company
and the payment of significant fines and penalties by the Company, which may have a material adverse effect on our financial condition, results of operations and cash flow. We anticipate that these matters will require us to expend significant
management time and incur significant legal and other expenses.

Substantial sales of our stock or equity in our
subsidiaries or the exercise or conversion of options or convertible securities may impact the market price of our common stock.

Our collaborative partner Sigma-Tau and affiliates hold a substantial amount of our stock. The stock is freely tradable and Sigma-Tau is
not under any obligation to SciClone which would prevent it from selling some or all of the stock it holds except for applicable U.S. insider trading regulations with respect to possession of material non-public information by Sigma-Tau or its
officers and directors.

In May 2009, we filed a Form S-3 Shelf registration with the Securities and Exchange Commission
(SEC) which was later declared effective by the SEC and will allow us to sell securities in one or more offerings. Future issuances of substantial amounts of our common stock could adversely affect the market price of our common stock.
Similarly, if we raise additional funds through the issuance of common stock or securities convertible into or exercisable for common stock or sell equity in a subsidiary, the percentage ownership of our present stockholders of the respective
entities will be reduced and the price of our common stock may fall.

Our cash and investments are subject to certain risks
which could materially adversely affect our overall financial position. *

We invest our cash in accordance with an
established internal policy and customarily in instruments which historically have been highly liquid and carried relatively low risk. However, with turmoil in the credit markets, similar types of investments have experienced losses in
value or liquidity issues which differ from their historical pattern. For example, we routinely have invested in money market funds with large financial institutions. One or more of these funds could experience losses or liquidity problems
and, although to date some of the largest financial institutions who sponsor such funds have offset similar losses, there is no assurance that our financial institutions would either not incur losses or would offset any losses were they to occur.

##### Table of Contents

Should any of our cash investments permanently lose value or have their liquidity impaired,
it would have a material and adverse effect on our overall financial position by imperiling our ability to fund our operations and forcing us to seek additional financing sooner than we would otherwise and such financing may not be available on
commercially attractive terms.

In addition, financial instruments may subject us to a concentration of credit risk.
Substantially all of our cash, and cash equivalents are held by a limited number of financial institutions including all of our term deposits held by financial institutions in Hong Kong and offshore. Such term deposits do not exceed federally
insured limits and to date, we have not experienced any losses on our deposits of cash and cash equivalents. However, if any of these instruments permanently lost value or had their liquidity impaired, it would also have a material and adverse
effect on our overall financial position by imperiling our ability to fund our operations and forcing us to seek additional financing sooner than we would otherwise and such financing may not be available on commercially attractive terms.

New accounting pronouncements may impact our financial position or results of operations.

Future changes in financial accounting standards may cause adverse, unexpected fluctuations in the timing of the recognition of revenues
or expenses and may affect our financial position or results of operations. New pronouncements and varying interpretations of pronouncements have occurred with frequency and may occur in the future and this may lead to changes in our accounting
policies in the future.

If we fail to maintain an effective system of internal controls, we may not be able to accurately
report our financial results. As a result, current and potential stockholders could lose confidence in our financial reporting, which would harm our business and the trading price of our stock.

Effective internal controls are necessary for us to provide reliable financial reports and to protect from fraudulent, illegal or
unauthorized transactions. If we cannot provide effective controls and reliable financial reports, our business and operating results could be harmed. Moreover, as a United States-based corporation doing business in China, these controls often need
to satisfy the requirements of Chinese law as well as the requirements of United States law which frequently differ in certain aspects. We have in the past discovered, and may in the future discover, areas of our internal controls that need
improvement. For example, our management determined that as of December 31, 2008 we had a material weakness in our internal controls related to our failure to expense approximately $540,000 in research and development costs related to changes
in the scope of activities performed by our clinical research organization during 2008. Although we have since taken steps to rectify this material weakness, there can be no assurance that we will be successful in this regard. Any failure to
implement and maintain controls over our financial reporting, or difficulties encountered in the implementation of improvements in our controls, could cause us to fail to meet our reporting obligations. Any failure to improve our internal controls
or to address identified weaknesses in the future, including with respect to our clinical research expenses, if they were to occur, could also cause investors to lose confidence in our reported financial information, which could have a negative
impact on the trading price of our stock.

New legislation may impact our financial position or results of operations.

Compliance with changing regulations concerning corporate governance and public disclosure has resulted in and may continue
to result in additional expenses. Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002, new SEC regulations and The NASDAQ Stock Market rules, are creating
uncertainty for companies such as ours and costs are increasing as a result of this uncertainty and other factors. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, we intend to invest all
reasonably necessary resources to comply with evolving standards, and this investment has and may continue to result in increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities
to compliance activities.

Currently a majority of our revenue is generated from customers located outside the United States,
and a substantial portion of our assets, including employees, are located outside the United States. United States income taxes and foreign withholding taxes have not been provided on undistributed earnings of non-United States subsidiaries, because
such earnings are intended to be indefinitely reinvested in the operations of those subsidiaries. President Obamas administration has recently announced initiatives that would substantially reduce our ability to defer U.S. taxes including:
repeal deferral of U.S. taxation of foreign earnings, eliminate utilization or substantially reduce our ability to claim foreign tax credits, and eliminates various tax deductions until foreign earnings are repatriated to the United States. If any
of these proposals are constituted into legislation, they could have a negative impact on our financial position and results of operations.

We may be subject to product liability lawsuits, and our insurance may be inadequate to
cover damages.

Clinical trials of any of our current and potential products or the actual commercial sales of our product
may expose us to liability claims from the use of these products. We currently carry product liability insurance. However, we cannot be certain that we will be able to maintain insurance on acceptable terms, if at all, for clinical and commercial
activities or that the insurance would be sufficient to cover any potential product liability claim or recall. If we fail to have sufficient coverage, our business, results of operations and cash flows could be adversely affected.

If we are unable to comply with environmental and other laws and regulations, our business may be harmed.

We are subject to various federal, state and local laws, regulations and recommendations relating to the use, manufacture, storage,
handling and disposal of hazardous materials and waste products (including radioactive compounds and infectious disease agents), as well as safe working conditions, laboratory and manufacturing practices and the experimental use of animals. The
extent of government regulation that might result from future legislation or administrative action in these areas cannot be accurately predicted.

We do not currently maintain hazardous materials at our facilities. While we outsource our research and development programs involving
the controlled use of biohazardous materials, if in the future we conduct these programs ourselves, we might be required to incur significant cost to comply with environmental laws and regulations. Further, in the event of an accident, we would be
liable for any damages that result, and the liability could exceed our resources.

We are at risk of securities class
action litigation.

In the past, securities class action litigation has often been brought against a company following a
decline in the market price of its securities. This risk is especially relevant for us because biotechnology companies have experienced greater than average stock price volatility in recent years. If we faced such litigation, it could result in
substantial costs and a diversion of managements attention and resources, which could harm our business.

Anti-takeover provisions in our charter documents and under Delaware law may make an acquisition of us, which may be beneficial to our
stockholders, more difficult.

Certain anti-takeover provisions of Delaware law and our charter documents as currently in
effect may make a change in control of our company more difficult, even if a change in control would be beneficial to our stockholders. Our charter documents contain certain anti-takeover provisions, including provisions in our certificate of
incorporation providing that stockholders may not cumulate votes, stockholders meetings may be called by stockholders only if they hold 25% or more of our common stock and provisions in our bylaws providing that the stockholders may not take
action by written consent. Additionally, our board of directors has the authority to issue 10 million shares of preferred stock and to determine the terms of those shares of stock without any further action by the stockholders. The rights of
holders of our common stock are subject to the rights of the holders of any preferred stock that may be issued. The issuance of preferred stock could make it more difficult for a third-party to acquire a majority of our outstanding voting stock.
Delaware law also prohibits corporations from engaging in a business combination with any holders of 15% or more of their capital stock until the holder has held the stock for three years unless, among other possibilities, the board of directors
approves the transaction. Our board of directors may use these provisions to prevent changes in the management and control of our company. Also, on December 18, 2006, our Board of Directors declared a dividend distribution of one Preferred
Stock Purchase Right (collectively, the Rights) for each outstanding share of our Common Stock, each Right which entitles the registered holder to purchase from the Company one one-thousandth of a share of the Companys Series D
Preferred Stock, $0.001 par value, at a price of $25.00 pursuant to a Rights Agreement dated as of December 19, 2006, between the Company and Mellon Investor Services LLC. The Rights have certain anti-takeover effects. Under certain
circumstances the Rights could cause substantial dilution to a person or group who attempts to acquire the Company on terms not approved by our Board of Directors. Although the Rights should not interfere with an acquisition of the Company approved
by the Board, the Rights may have the effect of delaying and perhaps improving the terms of an acquisition for our stockholders, or deterring an acquisition of the Company. Also, under applicable Delaware law, our board of directors may adopt
additional anti-takeover measures in the future.

Our business and operations are subject to the risks of being based in
particular locations known for earthquakes, other natural catastrophic disasters and service interruptions.

Our corporate
headquarters are located in the Silicon Valley area of Northern California, a region known for seismic activity. Although we maintain a disaster recovery policy that includes storage of important corporate data in a different geographic region of
the United States, all of our significant corporate data is stored in our headquarters facility and accordingly, a significant natural disaster, such as an earthquake, could have a material adverse impact on our business, operating results, and
financial condition. Most of our sales are into China for which we maintain a sole warehouse for finished goods in Hong Kong, which can experience severe typhoon storms. Although our distributors in China maintain several months supply of
our product, were our warehouse capability to be interrupted, either through a natural disaster such as flooding or through a service interruption, such as a lack of electricity to power required air conditioning, our ability to timely deliver
finished product to China could be adversely affected which in turn would materially adversely affect our sales and ensuing operating results.

We May Be Affected by Climate Change and Market or Regulatory Responses to Climate
Change.

Climate change, including the impact of global warming, could have a material adverse effect on our results of
operations, financial condition, and liquidity if it were to disrupt the demand, supply or delivery of product, management of our business, or result in cost increases as a result of government regulation.
