TERCICA, INC.

NOTES TO THE CONDENSED FINANCIAL STATEMENTS

(Unaudited)

1. Company and Basis of
Presentation

Company

Tercica, Inc. (the Company) is a biopharmaceutical company developing and marketing a portfolio of endocrine products. The Company currently has the following products and product candidates in its commercialization and
development portfolio:



| |  |  | Increlex®, which is approved for marketing in both the
United States and the European Union;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Somatuline® Depot, which is approved for marketing in both
the United States and Canada; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Two product candidates containing different combinations of Genentech Inc.s recombinant human growth hormone
(rhGH) (Nutropin AQ®), and recombinant human insulin-like growth factor-1 (rhIGF-1) (i.e., Increlex®).
One product candidate is for the treatment of short stature associated with low insulin-like growth factor-1 (IGF-1) levels and the other product candidate is for the treatment of adult growth hormone deficiency (AGHD). In
January 2008, the Company initiated dosing patients with Nutropin AQ® and Increlex® in a Phase II study for the treatment of
short stature associated with low IGF-1 levels.

Basis of Presentation

The accompanying unaudited condensed financial statements have been prepared in accordance with the requirements of the U.S. Securities and Exchange
Commission (SEC) for interim reporting. As permitted under those rules, certain footnotes or other financial information that are normally required by U.S. generally accepted accounting principles (GAAP) can be condensed or
omitted. In the opinion of management, the financial statements include all normal and recurring adjustments that are considered necessary for the fair presentation of the Companys financial position and operating results. The condensed
balance sheet at December 31, 2007 has been derived from the audited financial statements at that date.

The results of the
Companys operations can vary during each quarter of the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year or any future periods. The information included in this
quarterly report on Form 10-Q should be read in conjunction with the audited financial statements for the year ended December 31, 2007, included in the Companys Annual Report on Form 10-K for the year ended December 31, 2007,
filed with the SEC on February 29, 2008.

The preparation of financial statements in conformity with GAAP for interim financial
reporting requires management to make estimates and assumptions that affect the amounts reported in the condensed financial statements and accompanying notes. Actual results could differ from those estimates.

2. Significant Accounting Policies

During 2008, the
Company applied the new accounting standard Statement of Financial Accounting Standards (SFAS) No. 157, Fair Value Measurements(SFAS No. 157), related to the fair value measurements of the Companys
assets and liabilities as described more fully below. There have been no significant changes in the Companys significant accounting policies during the three months ended March 31, 2008 as compared to the significant accounting policies
described in the Companys Annual Report on Form 10-K for the year ended December 31, 2007.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined using the first-in,
first-out basis. The valuation of inventory requires the Company to estimate obsolete or excess inventory based on analysis of future demand for the Companys products. Due to the nature of the Companys business and our target markets, we
believe levels of inventory in the distribution channel is not significant, and changes in demand due to price changes from competitors and the introduction of new products are not significant factors when estimating the Companys excess or
obsolete inventory for Increlex® but can be significant factors in estimating excess or obsolete inventories for Somatuline®
Depot. If inventory costs exceed expected market value due to obsolescence or lack of demand, inventory write-downs may be recorded as deemed necessary by management for the difference between the cost and the market value in the period that
impairment is first recognized. Inventories may include products manufactured at facilities awaiting regulatory approval and are capitalized based on managements judgment of probable near term regulatory approval. In addition, inventories
include employee stock-based compensation expenses capitalized under SFAS No. 123R.

##### Table of Contents

In general, the process for evaluating whether there exists excess or obsolete inventory is not a complex
process and does not require significant management judgment. The factors considered in evaluating whether there exists excess or obsolete inventory are:



| |  |  | the Companys forecast of future demand, which is updated on a quarterly basis;
| | - |  | -------------------------------------------------------------------------------



| |  |  | the expiration date for each lot manufactured; and
| | - |  | --------------------------------------------------



| |  |  | any noncancelable open purchase orders associated with our commercial supply agreements.
| | - |  | ----------------------------------------------------------------------------------------

In May 2007, the Company began to transfer its manufacturing process to new facilities and as
such, there will be a period of time where the Company will need to cease production of Increlex® until the new manufacturing facilities are fully validated, approved by the Food &
Drug Administration (FDA) and operational. The Company is increasing its inventory levels in an effort to ensure that the Company has adequate supplies to meet future demand and therefore the Companys long-term Increlex® sales forecast will become more critical in managements evaluation of excess Increlex® inventories over the next few quarters.
Once the transfer of manufacturing facilities is complete, the Company will have more flexibility in the manufacturing schedule to ensure inventory supply is in line with a shorter forward demand forecast for Increlex®. As of March 31, 2008, we had total inventories of $18.8 million. The total inventory of $18.8 million at March 31, 2008 included work-in-process inventory of $5.5 million, at our new fill and finish
manufacturing agent that will be available to us as finished goods only upon a successful approval of manufacturing process transfer by the FDA. The FDA requires that when technical processes are transferred to a new manufacturer, a certain number
of conformance lots must be produced using the new manufacturers facilities and evaluated for process consistency.

Revenue Recognition

The Company recognizes revenue from the sale of its products and license and collaboration agreements pursuant to SAB No. 104,
Revenue Recognition, and Emerging Issues Task Force (EITF) Issue 00-21 Revenue Arrangements with Multiple Deliverables(EITF 00-21). Multiple element agreements entered into are evaluated under the provision of
EITF 00-21. The Company evaluates whether there is stand-alone value for the delivered elements and objective and reliable evidence of fair value to allocate revenue to each element in multiple element agreements. When the delivered element does not
have stand-alone value or there is insufficient evidence of fair value for the undelivered element(s), the Company recognizes the consideration for the combined unit of accounting in the same manner as the revenue is recognized for the final
deliverable, which is generally ratably over the longest period of involvement.

Product revenues. The Company recognizes revenue
from product sales when there is persuasive evidence that an arrangement exists, title passes, the price is fixed or determinable and collectibility is reasonably assured. The Company records provisions for discounts to customers and rebates to
government agencies and international distributors, which are based on contractual terms and regulatory requirements. The Companys product returns policy only allows for the return of product damaged in transit, product shipped in error by the
Company, or discontinued, withdrawn or recalled merchandise. To date, product returns have been de minimis and based on the Companys historical experience as well as the specialized nature of the Companys products, the Company
historically has not provided a reserve for product returns. The Company will continue to monitor returns in the future and will reassess the need to estimate a product returns reserve if the returns experience increases.

License revenues. License revenue generally includes upfront and continuing licensing fees and milestone payments. Nonrefundable upfront fees that
require the Companys continuing involvement in the manufacturing or other commercialization efforts by the Company are recognized as revenue ratably over the contractual term. Fees associated with substantive milestones, which are contingent
upon future events for which there is reasonable uncertainty as to their achievement at the time the agreement was entered into, are recognized as revenue when these milestones, as defined in each contract, are achieved.

Royalty revenues. The Company recognizes
royalty revenues from sales of Increlex® in Ipsens territory on a sliding scale from 15% to 25% of net sales. Royalties are recognized as earned in accordance with the contract terms
when royalties from Ipsen can be reasonably estimated and collectibility is reasonably assured.

Manufacturing Start-up Costs

Manufacturing start-up costs are comprised primarily of third-party costs related to the
establishment of alternative manufacturers for the Companys drug substance rhIGF-1 and drug product Increlex® and absorption of personnel costs supporting these activities. These
expenses include costs associated with the Companys contract manufacturers, pre-approval product manufacturing, process transfer, validation and qualification activities, and compliance-related support, pre-regulatory approval preparations for
current good manufacturing practices (cGMP) and FDA approval.

Valuation of Derivative Instruments

The Company issued a convertible note denominated in Euros in September 2007 and valued certain features embedded therein as a derivative liability. The
terms of the note provide that the holder may convert the note into shares of the Companys common stock based upon a fixed Euro amount per share. Because the conversion option is not fixed in the Companys functional currency (the U.S.
dollar), the conversion option is not considered indexed to the Companys common stock. Therefore, under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities(SFAS No. 133), the Company
accounts for the conversion option as an embedded derivative that is bifurcated and measured separately from the convertible note (the host instrument). The note is denominated in Euros and the liability must be remeasured into U.S. dollars each
quarter end based upon the then current Euro-U.S. dollar exchange ratio. Remeasurement of the liability is recorded as foreign currency gains or losses in other income and expense in the accompanying condensed statements of operations. The Company
estimates the fair value of its derivative liabilities each quarter-end using the Black-Scholes-Merton valuation model. This model is complex and requires significant judgments in the estimation of fair values based on various factors, including the
Companys current stock price and stock price volatility, the volatility of the Euro against the U.S. dollar, and other assumptions. Changes in the fair value of the embedded conversion option are recorded as non-cash gains and losses within
other income (expense) in the Companys condensed statements of operations with offsetting amounts classified on the condensed balance sheet in the convertible note host debt instrument. Changes in the fair value of the embedded conversion
option can have a material impact on the Companys financial statements. Upon conversion of the note into the Companys common stock in accordance with its terms or payment or expiration of the convertible note, the host debt instrument,
including the fair value of the embedded conversion option, will be reclassified into common stock and additional paid in capital at then current estimated fair values. The timing of any such conversion is outside of the Companys control.

The embedded derivative liability does not qualify for hedge accounting under SFAS No. 133 and therefore, subsequent changes in fair
value are recorded as non-cash valuation adjustments within other income (expense) in the condensed statements of operations.

Recent Accounting
Pronouncements

On January 1, 2008, the Company adopted SFAS No. 157. SFAS No. 157 provides guidance for using fair value
to measure assets and liabilities. SFAS No. 157 applies both to items recognized and reported at fair value in the financial statements and to items disclosed at fair value in the notes to the financial statements. SFAS No. 157 does not
change existing accounting rules governing what can or must be recognized and reported at fair value and clarifies that fair value is defined as the price received to sell an asset, or paid to transfer a liability, in an orderly transaction between
market participants at the measurement date. Additionally, SFAS No. 157 does not eliminate practicability exceptions that exist in accounting pronouncements amended by SFAS No. 157 when measuring fair value. As a result, the Company is not
required to recognize any new assets or liabilities at fair value. SFAS No. 157 also establishes a framework for measuring fair value. Fair value is generally determined based on quoted market prices in active markets for identical assets or
liabilities. If quoted market prices are not available, SFAS No. 157 provides guidance on alternative valuation techniques that place greater reliance on observable inputs and less reliance on unobservable inputs. See Note 9  Fair
Value of Financial Instruments in the notes to these condensed financial statements.

In February 2007, the FASB issued SFAS
No. 159, Fair Value Option for Financial Assets and Financial Liabilities(SFAS No. 159), which permits entities to elect to measure many financial instruments and certain other items at fair value that are not currently
required to be measured at fair value. This election is irrevocable. SFAS No. 159 was effective in the first quarter of fiscal 2008. The Company did not elect to apply the fair value option to any of our financial instruments.

In December 2007, the SEC issued SAB No. 110 (SAB 110). SAB 110 expresses the views of
the Staff regarding the use of the simplified method, as discussed in SAB No. 107, in developing an estimate of the expected term of plain vanilla share options in accordance with SFAS No. 123R. SAB 110 allows public companies
that do no have historically sufficient experience to provide a reasonable estimate to continue use of the simplified method for estimating the expected term of plain vanilla share option grants after December 31, 2007. The Company
currently uses the simplified method to estimate the expected term for share option grants as it does not have enough historical experience to provide a reasonable estimate. The Company will continue to use the simplified method until it has enough
historical experience to provide a reasonable estimate of expected term in accordance with SAB 110. SAB 110 was effective for the Company on January 1, 2008.

In December 2007, the EITF ratified the consensus on EITF Issue No. 07-1, Accounting for Collaborative Arrangements Related to the Development and Commercialization of Intellectual Property (EITF
07-1). EITF 07-1 concludes that transactions with third parties (that is, revenue generated and costs incurred by participants from transactions with parties outside of the collaborative arrangement) should be reported gross or net on the
appropriate line item in each participants respective financial statements pursuant to the guidance of EITF 99-19. EITF 07-1 is effective for fiscal years beginning after December 15, 2008, and requires retrospective application if
practicable. The Company expects that the adoption of EITF 07-1 will not have an impact on its financial position or results of operations.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities (SFAS No. 161), an amendment of SFAS No. 133. SFAS No. 161 requires enhanced disclosures
about an entitys derivative and hedging activities. These enhanced disclosures will discuss (a) how and why an entity uses derivative instruments, (b) how derivative instruments and related hedged items are accounted for SFAS
No. 133 and its related interpretations, and (c) how derivative instruments and related hedged items affect an entitys financial position, financial performance, and cash flows. SFAS No. 161 is effective for financial statements
issued for fiscal years beginning after November 15, 2008, with earlier adoption allowed. The Company has not completed the process of evaluating the impact on its financial position or results of operations that will result from adopting SFAS
No. 161.

In June 2007, the FASB ratified Emerging Issues Task Force (EITF) Issue No. 07-3, Accounting for
Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities (EITF No. 07-3). EITF No. 07-3 requires that nonrefundable advance payments for goods or services that will
be used or rendered for future research and development activities be deferred and capitalized and recognized as an expense as the goods are delivered or the related services are performed. EITF No. 07-3 is effective, on a prospective basis,
for fiscal years beginning after December 15, 2007. The adoption of EITF No. 07-3 did not have any impact on the Companys financial position or results of operations.

5. Long-Term Debt

In October 2006, the Company issued to Ipsen a convertible note in the principal amount of $25,037,000 (the First Convertible Note). The First Convertible Note accrues interest at a rate of
2.5% per year, compounded quarterly, and is convertible into the Companys common stock at an initial conversion price of $7.41 per share, subject to adjustment, which represents 3,504,530 shares at March 31, 2008.

##### Table of Contents

In September 2007, the Company issued to Ipsen two convertible notes in the principal amounts of
30,000,000, or $41,640,000 on the date of issuance (the Second Convertible Note), and $15,000,000 (the Third Convertible Note). The Second and Third Convertible Notes each accrue interest at a rate of 2.5% per
year, compounded quarterly, and are convertible into the Companys common stock at an initial conversion price of 5.92 per share for the Second Convertible Note and $7.41 per share for the Third Convertible Note, subject to
adjustment, which represents 5,135,854 and 2,051,569 shares, respectively, at March 31, 2008.

The conversion price of all the
Convertible Notes is subject to certain weighted-average price-based antidilution adjustments, which, if triggered, would result in an increase of the number of shares of common stock issuable upon conversion of the Convertible Notes. The entire
principal balance and accrued interest under all the Convertible Notes is due and payable on the later to occur of October 13, 2011 or the second anniversary of the date on which Ipsen (or subsequent holders of the Convertible Notes)
notifies the Company that it will not convert the Convertible Notes in full. Notwithstanding the foregoing, Ipsen (or the subsequent holders of the Convertible Notes) is entitled to declare all amounts outstanding under the Convertible Notes
immediately due and payable: (i) if an event of default occurs (as set forth in the Convertible Notes); (ii) for so long as Ipsens approval rights as set forth in the affiliation agreement the Company entered into pursuant to its
collaboration with Ipsen remain in effect, if any other person or group acquires beneficial ownership of greater than 9.9% of the Companys common stock (or if such person or group that already has beneficial ownership of greater than 9.9% of
the Companys common stock increases its beneficial ownership); or (iii) in the event that the Ipsens approval rights as set forth in the affiliation agreement cease to remain effective, if any other person or group acquires
beneficial ownership of greater than 50% of the Companys common stock.

Because the Second Convertible Note has a conversion price
stated in a foreign currency, the conversion feature constitutes a derivative liability. The Company initially valued the derivative liability associated with the Second Convertible Note at 9,220,000 or $12,797,000 on the date of issuance,
September 17, 2007. This amount was accounted for as a reduction in the initial carrying value of the Second Convertible Note and separately accounted for as a derivative liability. This discount to the Second Convertible Note, as a result of
this bifurcation, is being accreted over four years using the effective interest method. The carrying value, which approximates the fair value, on September 17, 2007 of the Second Convertible Note was 20,780,000, or approximately
$28,843,000, which is net of the discount plus accretion and accrued interest. At March 31, 2008 the carrying value was 22,173,000, or $35,033,000 which approximates fair value.

The Convertible Notes including accrued interest, consisted of the following (in thousands):

As of March 31, 2008, the Company accrued $932,000 of cumulative interest expense on the
First Convertible Note, of which $161,000 was recorded as interest expense in the three months ended March 31, 2008. If not earlier converted or repaid, the amount payable under the First Convertible Note on October 13, 2011 would be
$28,362,000, including cumulative interest of $3,325,000.

As of March 31, 2008, the Company recorded valuation adjustment expense of
$4,316,000 representing a decrease in value of the derivative liability associated with the Second Convertible Note. This amount was recorded to other income in the condensed statements of operations. The Company accrued $616,000 of cumulative
interest expense on the Second Convertible Note, of which $282,000 was recorded as interest expense in the three months ended March 31, 2008. The Company accrued $1,562,000 of cumulative non-cash accretion charges, of which $697,000 was
recorded as amortization expense for the three months ended March 31, 2008. If not earlier converted or repaid, the amount payable under the Second Convertible Note on October 13, 2011 would be 33,206,000, including cumulative
interest of 3,206,000.

As of March 31, 2008, the Company accrued $202,000 of cumulative interest expense on the Third
Convertible Note, of which $94,000 was recorded as interest expense in the three months ended March 31, 2008. If not earlier converted or repaid, the amount payable under the Third Convertible Note on October 13, 2011 would be $16,603,000,
including cumulative interest of $1,603,000.

6. Stockholders Equity

Ipsen Warrant

Concurrently with the issuance of the First Convertible Note, the Company issued a warrant to Ipsen, which is exercisable for such number of shares of the
Companys common stock equal to the greater of (i) 4,948,795 shares of the Companys common stock (the Baseline Amount) or (ii) the Baseline Amount plus a variable amount of shares of the Companys common stock,
which variable amount will fluctuate throughout the term of the warrant. The number of shares of the Companys common stock issuable upon exercise of the warrant as of October 13, 2006, the date of issue, was 5,026,712, with a fair value
of $13,622,000, estimated using the Black-Scholes-Merton valuation model, which was recorded to additional paid-in capital. The number of shares of the Companys common stock issuable upon exercise of the warrant as of March 31, 2008 was
4,948,795. The exercise term of the warrant is five years beginning on October 13, 2006, and the warrant is exercisable, in full or in part, at an initial exercise price of $7.41 per share, subject to adjustment, including certain
weighted-average price-based antidilution adjustments.

7. Stock-Based Compensation

Stock-based compensation expense is measured at the grant date, based on the fair value of the award, and is recognized as expense over the remaining
requisite service period. Total stock-based compensation expense of $1,470,000 and $1,501,000 was recorded during the three months ended March 31, 2008 and 2007, respectively.

Stock Options

The fair value of each option grant is estimated at the grant date using the
Black-Scholes-Merton valuation model with the following weighted-average assumptions:



|                        |  |                             |   |  |      |

|Expected volatility     |  | 62.3                        | % |  | 63.4 | %
|Expected term (years)   |  | 6.2                         |   |  | 6.3  |  
|Risk-free interest rate |  | 3.0                         | % |  | 4.6  | %
|Dividend yield          |  |                            |   |  |     |  

The Companys computation of expected volatility for the three months ended March 31,
2008 and 2007 is based on an average of the historical volatility of the Companys stock and the historical volatility of a peer-group of similar companies. The Companys computation of expected term in the three months ended
March 31, 2008 and 2007 utilizes the simplified method in accordance with SAB 107, as modified by SAB 110. The risk-free interest rate for periods within the contractual life of the option is based on treasury constant maturities rates in
effect at the time of grant. The Company recognizes stock-based compensation expense for the fair values of these awards on a straight-line basis over the requisite service period of each of these awards.

As of March 31, 2008, unrecognized stock-based compensation expense related to stock options of
$13,058,000 was expected to be recognized over a weighted-average period of 2.7 years.

Restricted Stock Units

In February 2008, the Board of Directors of the Company amended the terms of the Companys 2004 Stock Plan (the Plan) to provide for the
award of restricted stock units (RSUs). In March 2008, under the Plan, the Company granted RSUs to eligible employees, including executives. Each RSU represents a right to receive one share of the Companys common stock (subject to
adjustment for certain specified changes in the capital structure of the Company) upon the completion of a specific period of continued service. The Company also provides eligible grantees with the opportunity to defer the delivery of shares.

The Company values the RSUs at the market price of the Companys common stock on the date of grant. The Company recognizes non-cash
compensation expense for the fair values of these RSUs on a straight-line basis over the requisite service period of these awards, which is generally four years.

A summary of RSU activity is as follows:

The weighted-average grant date fair value of RSUs granted during the three months ended
March 31, 2008 was $6.13. As of March 31, 2008, unrecognized stock-based compensation expense related to non-vested RSUs of $1,222,000 was expected to be recognized over a weighted-average period of four years. Stock-based compensation
expense related to RSUs was approximately $5,100 for the three months ended March 31, 2008.

8. Net Loss Per Share

Basic net loss per share is calculated by dividing the net loss by the weighted-average number of common shares outstanding for the period, without
consideration for common stock equivalents. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common share equivalents outstanding for the period determined using the treasury-stock method for warrants
and options and the as-if converted method for the Convertible Notes the Company issued to Ipsen. For purposes of this calculation, common stock subject to repurchase by the Company, preferred stock, options, restricted stock units and warrants are
considered to be common stock equivalents and are only included in the calculation of diluted net loss per share when their effect is dilutive.

9. Fair Value of Financial Instruments

Financial instruments and derivative liabilities are presented at fair value. Fair value is defined as the price at which an asset could be exchanged in a
current transaction between knowledgeable, willing parties. A liabilitys fair value is defined as the amount that would be paid to transfer the liability to a new obligor, not the amount that would be paid to settle the liability with the
creditor. Where available, fair value is based on observable market prices or parameters or derived from such prices or parameters. Where observable prices or inputs are not available, valuation models are applied. These valuation techniques involve
some level of management estimation and judgment, the degree of which is dependent on the price transparency for the instruments or market and the instruments complexity.

Beginning January 1, 2008, assets and liabilities recorded at fair value in the condensed balance sheets are categorized based upon the level of
judgment associated with the inputs used to measure their fair value. Hierarchical level  defined by SFAS No. 157 and directly related to the amount of subjectivity associated with the inputs to fair valuation of these assets and
liabilities  are as follows:



| |  |  | Level 1 - Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------

Fair valued assets that are generally included in this category are cash equivalents comprised of money market funds, and restricted cash.



| |  |  | Level 2 - Inputs (other than quoted prices included in Level 1) are either directly or indirectly observable for the asset or liability through correlation with
market data at the measurement date and for the duration of the instruments anticipated life.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Fair valued assets
and liabilities that are generally included in this category are corporate bonds, commercial paper, federal agency bonds, asset-backed securities and embedded derivative liabilities.



| |  |  | Level 3 - Inputs reflect managements best estimate of what market participants would use in pricing the asset or liability at the measurement date.
Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The Company currently does not have any fair valued assets or liabilities classified as Level 3.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of

Tercica, Inc.

We have reviewed the condensed balance sheet of Tercica, Inc.
as of March 31, 2008, and the related condensed statements of operations for the three-month periods ended March 31, 2008 and 2007, and the condensed statements of cash flows for the three-month periods ended March 31, 2008 and 2007.
These financial statements are the responsibility of the Companys management.

We conducted our review in accordance with the standards of the Public
Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is
substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the condensed
financial statements referred to above for them to be in conformity with U.S. generally accepted accounting principles.

We have previously audited, in
accordance with the standards of the Public Company Accounting Oversight Board (United States), the balance sheet of Tercica, Inc. as of December 31, 2007, and the related statements of operations, stockholders equity, and cash flows for
the year then ended not presented herein and in our report dated February 27, 2008, we expressed an unqualified opinion on those financial statements and included explanatory paragraphs for the Companys change in its method of accounting
for stock-based compensation in accordance with guidance provided in Statement of Financial Accounting Standards No. 123R, Share-Based Payment. In our opinion, the information set forth in the accompanying condensed balance sheet as
of December 31, 2007, is fairly stated, in all material respects, in relation to the balance sheet from which it has been derived.

Overview

We are a biopharmaceutical company
developing and marketing a portfolio of endocrine products. We currently have the following products and product candidates in our commercialization and development portfolio:



| |  |  | Increlex®, which is approved for marketing in both the
United States and the European Union;
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Somatuline® Depot, which is approved for marketing in both
the United States and Canada; and
| | - |  | --------------------------------------------------------------------------------------------



| |  |  | Two product candidates containing different combinations of Genentech Incs recombinant human growth hormone, or
rhGH (Nutropin AQ®), and recombinant human insulin-like growth factor-1, or rhIGF-1 (i.e., Increlex®). One product candidate is
for the treatment of short stature associated with low insulin-like growth factor-1, or IGF-1, levels and the other product candidate is for the treatment of adult growth hormone deficiency, or AGHD. In January 2008, we initiated dosing patients
with Nutropin AQ® and Increlex® in a Phase II study for the treatment of short stature associated with low IGF-1 levels.
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Increlex®. We market Increlex® as a long-term replacement therapy for the treatment of short stature in children with severe primary insulin-like growth factor-1 deficiency, or severe
Primary IGFD, and for children with growth hormone gene deletion who have developed neutralizing antibodies to growth hormone. We commenced marketing Increlex® in the United States in
January 2006. We are currently conducting a Phase IIIb clinical trial for the use of Increlex® for the treatment of short stature in children with Primary IGFD, a less severe and more
prevalent form of insulin-like growth factor-1 deficiency, or IGFD. Patient enrollment for this trial was completed in July 2007, and we expect to present data from this trial at a medical conference in the fourth quarter of 2008.

In August 2007, the European Commission granted marketing authorization for Increlex® in the European Union for the long-term treatment of growth failure in children and adolescents with severe Primary IGFD. Pursuant to our worldwide strategic collaboration with Ipsen that was
completed in October 2006, we granted to Ipsen and its affiliates the exclusive right under our patents and know-how to develop and commercialize Increlex® in all countries of the world
except the United States, Japan, Canada, and for a certain period of time, Taiwan and certain countries of the Middle East and North Africa for all indications, other than treatment of central nervous system and diabetes indications. In 2007, Ipsen
launched Increlex® in Austria, Germany, Great Britain, Greece, Hungary, Spain and the Czech Republic, and expects to launch Increlex® in additional European countries during 2008.

Increlex® generated net product revenues of $3.4 million in the three-month period ended March 31, 2008.

Somatuline® Depot.
Pursuant to our worldwide strategic collaboration with Ipsen, we have the exclusive right under Ipsens patents and know-how to develop and commercialize Somatuline® Depot in the
United States and in Canada for all indications other than opthalmic indications. In territories outside the United States, including Canada, the product is known as Somatuline®
Autogel®. On August 30, 2007, Ipsen received notice of approval from the Food & Drug Administration (FDA) for marketing Somatuline® Depot in the United States for the long-term treatment of acromegaly in patients who have had an inadequate response to surgery and/or radiotherapy, or for whom surgery and/or radiotherapy is not an option.
Acromegaly is a hormonal disorder that results when a tumor in the pituitary gland produces excess growth hormone, resulting in overproduction of IGF-1. In July 2006, Somatuline®
Autogel® was approved for marketing by Health Canada for the same indication. Somatuline® Autogel® has received provincial formulary listings for reimbursement approval in the

provinces of Quebec, Nova Scotia, Newfoundland and Labrador, New Brunswick, Saskatchewan, and for Alberta Blue Cross and we are awaiting reimbursement
approval in the province of Ontario. At present, we have contracted sales and marketing operations in Canada to a third party. We launched Somatuline® Depot in November 2007 in the United
States.

Somatuline®
Depot generated net product revenues of $1.0 million in the three-month period ended March 31, 2008.

Growth hormone/IGF-1 Combination Product Candidates. In July 2007, we entered into a combination product development and commercialization agreement with Genentech that governs the development, manufacture and
worldwide commercialization of two product candidates containing Nutropin AQ®, Genentechs rhGH, and Increlex®, for the
treatment of all indications except those of the central nervous system. In January 2008, we began dosing the first patients in a Phase II clinical study evaluating the combination of the Nutropin AQ® and Increlex® for the treatment of short stature associated with low IGF-1 levels. The primary objective of this trial is to assess the efficacy, measured
as first-year height velocity, and safety of three different combination regimens of Nutropin AQ® and Increlex® compared to
Nutropin AQ® alone in the treatment of short stature associated with low IGF-1 levels. Although the goal of the program is to develop a co-mixture of Nutropin AQ® and Increlex® administered as a single injection, the patients enrolled in this trial have received separate injections of each of Nutropin AQ® and Increlex®.

As of March 31, 2008, we had approximately $94.9 million in cash, cash equivalents and
short-term investments. We have generated limited revenues from product sales to date and we have funded our operations since inception primarily through the private placements of equity securities and public offerings of our common stock, as well
as through our collaboration with Ipsen. Since our inception we have incurred substantial net losses and we expect to incur substantial net losses for the foreseeable future as we attempt to develop, market and sell Increlex® and Somatuline® Depot, and as we attempt to develop growth hormone/IGF-1 combination products under our combination product
collaboration with Genentech. We are unable to predict the extent of any future losses or when we will become profitable, if ever.

Critical Accounting
Policies and the Use of Estimates

Our managements discussion and analysis of our financial condition and results of operations
are based on our financial statements which have been prepared in accordance with accounting principles generally accepted in the United States, or GAAP, for interim financial information. The preparation of our financial statements requires
management to make estimates and assumptions that affect the amounts reported in our financial statements and accompanying notes. Actual results could differ materially from those estimates. During 2008, we adopted the new accounting standard
Statement of Financial Accounting Standards, or SFAS, No. 157, Fair Value Measurements, related to the fair value measurements of our assets and liabilities as described more fully below. Other than the adoption of SFAS No. 157,
there have been no significant changes in our significant accounting policies during the three months ended March 31, 2008 as compared to the significant accounting policies described in our Annual Report on Form 10-K for the year ended
December 31, 2007. For a discussion of these critical accounting policies, please see the discussion in our Annual Report on Form 10-K for the fiscal year ended December 31, 2007.

The items in our condensed financial statements requiring significant estimates and judgments are as follows:

Revenue Recognition

We
recognize revenue from the sale of our products and license and collaboration agreements pursuant to Staff Accounting Bulletin No. 104, Revenue Recognition, and Emerging Issues Task Force (EITF) Issue 00-21 Revenue
Arrangements with Multiple Deliverables(EITF 00-21). Multiple element agreements entered into are evaluated under the provision of EITF 00-21. We evaluate whether there is stand-alone value for the delivered elements and objective
and reliable evidence of fair value to allocate revenue to each element in multiple element agreements. When the delivered element does not have stand-alone value or there is insufficient evidence of fair value for the undelivered element(s), we
recognize the consideration for the combined unit of accounting in the same manner as the revenue is recognized for the final deliverable, which is generally ratably over the longest period of involvement.

Product revenues. We recognize revenue from product sales when there is persuasive evidence that an arrangement exists, title passes, the price is
fixed or determinable and collectibility is reasonably assured. We record provisions for discounts to customers and rebates to government agencies and international distributors, which are based on contractual terms and regulatory requirements. The
rebates and discounts may require management judgment to estimate percentage of eligible sales to these customers. Our product returns policy only allows for the return of product damaged in transit, product shipped in error by us, or discontinued,
withdrawn or recalled merchandise. To date, product returns have been de minimis and based on our historical experience as well as the specialized nature of our products, we historically have not provided a reserve for product returns. We will
continue to monitor returns in the future and will reassess the need to estimate a product returns reserve if the returns experience increases.

License revenues. License revenue generally includes upfront and continuing licensing fees and
milestone payments. Nonrefundable upfront fees that require our continuing involvement in manufacturing or other commercialization efforts by us are recognized as revenue ratably over the contractual term. Fees associated with substantive
milestones, which are contingent upon future events for which there is reasonable uncertainty as to their achievement at the time the agreement was entered into, are recognized as revenue when these milestones, as defined in the contract, are
achieved.

Royalty revenues. We recognize royalty revenues from sales of
Increlex® in Ipsens territory on a sliding scale from 15% to 25% of net sales. Royalties are recognized as earned in accordance with the contract terms and when collectibility is
reasonably assured.

Inventories

Inventories are stated at the lower of cost or market. Cost is determined using the first-in,
first-out basis. The valuation of inventory requires management to estimate obsolete or excess inventory based on analysis of future demand for our products. Due to the nature of our business and our target market, levels of inventory in the
distribution channel, changes in demand due to price changes from competitors and introduction of new products are not significant factors when estimating our excess or obsolete inventory for Increlex® but can be significant factors in estimating excess or obsolete inventories for Somatuline® Depot. If inventory costs exceed expected market value due to
obsolescence or lack of demand, inventory write-downs may be recorded as deemed necessary by management for the difference between the cost and the market value in the period that impairment is first recognized. Inventories may include products
manufactured at facilities awaiting regulatory approval and are capitalized based on our judgment of probable near term regulatory approval. In addition, inventories include employee stock-based compensation expenses capitalized under SFAS
No. 123R.

In general, the process for evaluating whether there exists excess or obsolete inventory is not a complex process and does
not require significant management judgment. The factors considered in evaluating whether there exists excess or obsolete inventory are:



| |  |  | our forecast of future demand, which is updated on a quarterly basis;
| | - |  | ---------------------------------------------------------------------



| |  |  | the expiration date for each lot manufactured;
| | - |  | ----------------------------------------------



| |  |  | any noncancelable open purchase orders associated with our commercial supply agreements.
| | - |  | ----------------------------------------------------------------------------------------

In May 2007, we began to transfer our manufacturing process to new facilities and as such, there
will be a period of time where we will need to cease production of Increlex® until the new manufacturing facilities are fully validated, approved by the Food & Drug Administration
(or FDA), and operational. We are increasing our inventory levels in an effort to ensure that we have adequate supplies to meet future demand and therefore our long-term Increlex® sales
forecast will become more critical in managements evaluation of excess Increlex® inventories over the next few quarters. Once the transfer of manufacturing facilities is complete, we
will have more flexibility in the manufacturing schedule to ensure inventory supply is in line with a shorter forward demand forecast for Increlex®. As of March 31, 2008, we had total
inventories of $18.8 million. Total inventories of $18.8 million included in work-in-process inventory of $5.5 million at our new fill and finish manufacturing agent, that will be available to us as finished goods only upon a successful approval of
manufacturing process transfer by the FDA. The FDA requires that when technical processes are transferred to a new manufacturer, a certain number of conformance lots must be produced using the new manufacturers facilities and evaluated for process
consistency.

Valuation of Derivative Instruments

We issued a convertible note denominated in Euros in September 2007 and valued certain features embedded therein as derivative liabilities under SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activitiesor SFAS No. 133. We estimate the fair value of our derivative liabilities each quarter using the Black-Scholes-Merton valuation model. This model is complex and
requires significant judgments in the estimation of fair values based on certain assumptions. Factors affecting the amount of these liabilities include changes the market value of our common stock, changes in Euro to U.S. dollar currency exchange
rates and other assumptions. Changes in value are recorded as non-cash valuation adjustments within other income (expense) in our statement of operations. These changes in the carrying value of derivatives can have a material impact on our financial
statements (see Part I, Item 3  Qualitative and Quantitative Disclosures about Market Risk of this Form 10-Q). The derivative liabilities may be recorded into stockholders equity upon conversion, payment or expiration of
the convertible notes, the timing of which is outside our control.

The embedded derivative liability does not qualify for hedge accounting
under SFAS No. 133 and therefore, subsequent changes in fair value are recorded as non-cash valuation adjustments within other income (expense) in the condensed statements of operations.

Recent Accounting Pronouncements

In the first quarter of 2008, we adopted SFAS No. 157,Fair Value Measurements(SFAS No. 157), for financial assets and liabilities. This standard does not apply measurements related to
share-based payments, nor does it apply to measurements related to inventory.

SFAS No. 157 discusses valuation techniques, such as
the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost). The statement utilizes a fair value
hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The following is a brief description of those three levels:



| |  |  | Level 1: Inputs are unadjusted, quoted prices in active markets for identical assets or liabilities at the measurement date.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 2: Inputs (other than quoted prices included Level 1) are either directly or indirectly observable for the asset or liability through correlation with market
data at the measurement date and for the duration of the instruments anticipated life.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Level 3: Inputs reflect managements best estimate of what market participants would use in pricing the asset or liability at the measurement date.
Consideration is given to the risk inherent in the valuation technique and the risk inherent in the inputs to the model.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The impact of adoption of SFAS No. 157 is discussed in Note 9, Fair Value of Financial Instruments in the Notes to Condensed Financial Statements of this Form 10-Q. The fair values of our short-term investments and
derivative liabilities are based on Level 2 inputs that are either directly or indirectly observable for the asset or liability through correlation with market data at the measurement date and for the duration of the instruments anticipated
life.

In February 2007, the FASB issued SFAS No. 159, Fair Value Option for Financial Assets and Financial Liabilities,or
SFAS No. 159, which permits entities to elect to measure many financial instruments and certain other items at fair value that are not currently required to be measured at fair value. This election is irrevocable. SFAS No. 159 was
effective in the first quarter of fiscal 2008. We did not elect to apply the fair value option to any of our financial instruments.

In
December 2007, the SEC issued SAB No. 110 or SAB 110. SAB 110 expresses the views of the staff regarding the use of the simplified method, as discussed in SAB No. 107, in developing an estimate of the expected term of plain
vanilla share options in accordance with SFAS No. 123R. SAB 110 allows public companies which do no have historically sufficient experience to provide a reasonable estimate to continue use of the simplified method for estimating the
expected term of plain vanilla share option grants after December 31, 2007. We currently uses the simplified method to estimate the expected term for share option grants as it does not have enough historical experience to provide a
reasonable estimate. We will continue to use the simplified method until it has enough historical experience to provide a reasonable estimate of expected term in accordance with SAB 110. SAB 110 was effective for us on January 1, 2008.

In December 2007, the EITF ratified the consensus on EITF Issue No. 07-1, Accounting for Collaborative Arrangements Related to the
Development and Commercialization of Intellectual Property, or EITF 07-1. EITF 07-1 concludes that transactions with third parties (that is, revenue generated and costs incurred by participants from transactions with parties outside of the
collaborative arrangement) should be reported gross or net on the appropriate line item in each participants respective financial statements pursuant to the guidance of EITF 99-19. EITF 07-1 is effective for fiscal years beginning after
December 15, 2008, and requires retrospective application if practicable. We expect that the adoption of EITF 07-1 will not have an impact on our financial position or results of operations.

In March 2008, the FASB issued SFAS No. 161, Disclosures about Derivative Instruments and Hedging Activities, or SFAS No. 161, an
amendment of SFAS No. 133. SFAS No. 161 requires enhanced disclosures about an entitys derivative and hedging activities. These enhanced disclosures will discuss (a) how and why an entity uses derivative instruments,
(b) how derivative instruments and related hedged items are accounted for under SFAS No. 133 and its related interpretations, and (c) how derivative instruments and related hedged items affect an entitys financial position,
financial performance, and cash flows. SFAS No. 161 is effective for financial statements issued for fiscal years beginning after November 15, 2008, with earlier adoption allowed. We have not completed the process of evaluating the impact
on our financial position or results of operations from adoption of SFAS No. 161.

In June 2007, the FASB ratified Emerging Issues Task Force (EITF) Issue No. 07-3,
Accounting for Nonrefundable Advance Payments for Goods or Services Received for Use in Future Research and Development Activities (EITF No. 07-3). EITF No. 07-3 requires that nonrefundable advance payments for goods or
services that will be used or rendered for future research and development activities be deferred and capitalized and recognized as an expense as the goods are delivered or the related services are performed. EITF No. 07-3 is effective, on a
prospective basis, for fiscal years beginning after December 15, 2007. The adoption of EITF No. 07-3 did not have any impact on our financial position or results of operations.

Net Revenues

Net revenues consisted of net product sales of Increlex® and Somatuline® Depot, amortized license revenue associated with our Increlex® license and
collaboration agreement with Ipsen, and royalty revenues from Ipsen for sales of Increlex® in the European Union.

Net Product Sales

Net product sales of $4.3 million for the three-month period ended March 31, 2008 increased
$3.3 million over the same period in 2007, primarily due to growth in Increlex® net product sales of $2.3 million and net product sales of Somatuline® Depot of $1.0 million. The growth of net Increlex® product sales in the three-month period ended March 31, 2008 was primarily due to continued
expansion of our patient base and three price increases since the first quarter of 2007, and to a lesser extent transition of a number of patients receiving IPLEX to treatment with
Increlex® following the settlement agreement with Insmed Inc. in March 2007. In the fourth quarter of 2007, we began shipment of Increlex® to Ipsen for European Union commercial distribution which added $0.3 million to net product sales in the three-month period ended March 31, 2008 compared to the same period in 2007. In November 2007, we launched
Somatuline® Depot in the United States, which added $1.0 million to net product sales in the three-month period ended March 31, 2008 compared to the same period in 2007.

We expect both Increlex® and
Somatuline® Depot product sales to increase over the next several quarters, however, we do not expect net Increlex® product sales
to increase at the same rate on a quarter over quarter basis as we experienced from the quarter ended March 31, 2007 to the quarter ended March 31, 2008.

License Revenue

License revenues represent
amortization of the upfront license payment in connection with our Increlex® license and collaboration agreement with Ipsen which was $0.2 million for both of the three months ended
March 31, 2008 and 2007. We are amortizing the upfront payment, received in October 2006 of 10.0 million, or $12.4 million, over a period of approximately 16 years based on the expected term of the license under this agreement. At
present, we do not anticipate any significant additional licensing or milestone payments related to or for Increlex® in future periods.

Under the terms of our combination product collaboration with Genentech, we may receive certain milestone payments in the future if Genentech elects to
exercise their opt-in right; however, we are unable to predict the timing or the likelihood of any such payments.

Royalty Revenue

We recorded royalty revenue of $65,000 in the three months ended March 31, 2008 from sales of
Increlex® in the European Union by Ipsen. There were no royalty revenues in the first three months of 2007. We expect our royalty revenues to increase over the next several quarters as
Ipsen continues to expand their Increlex® distribution in the European Union.

Cost of Sales

Our cost of sales represents the cost of
production, royalties owed to our licensors, fixed and variable distribution shipping and handling costs, inventory write-downs/write-offs based on our review of obsolete, excess, expired and failed inventory lots, and other costs related to
production activities. Prior to regulatory approval of Increlex® in August 2005, drug supply production costs were charged to research and development. Beginning in the fourth quarter of
2005, with the marketing approval of Increlex® by the FDA, we began capitalizing these production costs to inventory and began to charge cost of sales in the first quarter of 2006 as units
of Increlex® were sold.

Cost of sales for the three-month period ended March 31, 2008 increased $2.6 million over the same period in 2007. The increase in 2008 was primarily due to higher sales volume as more Increlex® units were sold and we commenced marketing of Somatuline® Depot, and increased absorption of personnel and other costs. In the three months ended
March 31, 2008, the cost of Increlex® sales were $2.7 million and the cost of Somatuline® Depot sales were $0.4 million.

Cost of sales as a percentage of net product sales in the three-month period ended March 31, 2008 was higher than the same period in
2007 primarily due to higher absorption of personnel and other costs under cost of sales. Some of these costs were previously allocated to research and development.

We expect cost of sales as a percentage of net product sales to decrease in future periods as
fixed costs are absorbed over larger production volumes, as our sales mix changes over time and as manufacturing equipment related depreciation costs cease in the third quarter of 2008. The depreciation of manufacturing equipment is related to
equipment owned by us at Lonza Baltimore. This facility will cease Increlex® production in the third quarter of 2008 and we will not own manufacturing equipment at our contract
manufacturers new facility.

Although we expect cost of sales as a percentage of net product sales to decrease in future periods,
there can be no assurances that cost of sales as a percentage of net product sales will decrease due to uncertainties inherent in the manufacturing process.

Manufacturing Start-up Costs

Manufacturing start-up costs consisted primarily of costs associated with the transfer of our manufacturing operations to alternate sites. We commenced transfer of our fill and finish operations in November 2006 and the transfer of
Increlex® drug substance production in May 2007. The increase in the three-month period ended March 31, 2008 was primarily due to the increase in manufacturing activities at both
facilities in the first quarter of 2008 compared to the same period in 2007. An additional $1.2 million of amortized costs associated with these projects will be recorded over the remaining transfer period, which is expected to occur through June
2008. There will be additional associated transfer activities and costs that will continue through the end of 2008, as we prepare for FDA approval of both transfer sites.

Research and Development Expenses

Research and development expenses consisted primarily of
costs associated with clinical, regulatory, manufacturing development and acquired rights to technology or products in development. Clinical and regulatory activities included the preparation, implementation, and management of our clinical trials
and clinical assay development, as well as regulatory compliance, data management and biostatistics. The costs associated with conducting clinical trials and post-marketing expenses, which include Phase IV and investigator-sponsored trials and
product registries, are included in research and development expenses. Manufacturing development activities included pre-regulatory approval activities associated with technology transfer, pharmaceutical development, process and development and
validation, quality control and assurance, analytical services, as well as preparations for current good manufacturing practices, or cGMP, and regulatory inspections. In addition to these manufacturing development and clinical activities, license
payments for patents and know-how to develop and commercialize products, are also recorded as research and development expense.

Research and development expenses of $6.1 million for the three months ended March 31, 2008
increased $1.2 million over the same period in 2007. The increase in 2008 was primarily due to an increase in third party contractor costs of $0.8 million and payroll related costs of $0.4 million. The increase in third-party contractor costs in
2008 was primarily due to an increase in clinical activities associated with growth hormone/IGF-1 combination product candidates as well as the Increlex® product registry, partially offset
by a decrease in activities associated with our European marketing authorization application, or MAA. The increase in payroll related costs in 2008 was primarily due to increased personnel compared to 2007.

##### Table of Contents

The $6.1 million in research and development
expense in the three-month period ended March 31, 2008 was comprised primarily of personnel and related costs of $3.3 million, third-party contract costs related to our clinical activities for Increlex® Primary IGFD and severe Primary IGFD of $1.5 million, clinical activities associated with growth hormone/IGF-1 combination product candidates of $0.9 million and Somatuline® Depot clinical activities in acromegaly of $0.4 million. The $4.9 million in research and development expense recorded for the same period in 2007 was comprised primarily of personnel and related costs of $2.9
million, third party contract costs related to our clinical activities for Increlex® Primary IGFD and severe Primary IGFD of $1.7 million, and clinical activities for Somatuline® Depot in acromegaly of $0.3 million.

We expect our research and development expenses to increase for the remainder of 2008 as we undertake clinical development activities for Increlex®, Somatuline® Depot, and growth hormone/IGF-1 combination product candidates and other projects. Our projects or intended projects may be subject to change from time to time as we evaluate our research and
development priorities and available resources.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consisted primarily of payroll and related costs associated with sales, marketing and medical science
personnel, corporate administration and executive management, commercial activities including cost of free drug, professional services including legal and accounting services, medical education and other administrative costs.

Selling, general and administrative expenses of $12.4 million for the three-month period ended
March 31, 2008 increased $2.8 million over the same period in 2007. The increase in 2008 was primarily due to an increase in sales and marketing expenses of $2.7 million and payroll and related costs of $0.7 million, partially offset by
decreased expenses associated with litigation of $0.7 million. The increase in sales and marketing activities was primarily related to increased costs associated with product promotions, medical education, costs in support of the launch of
Somatuline® Depot in the U.S. and Canada as well as additional physician focused programs in support of Increlex®. The increase
in payroll and related expenses was primarily due to additional sales and medical science personnel and non-cash stock compensation expense.

The $12.4 million in selling, general and administrative expenses for the three-month period ended March 31, 2008 was comprised primarily of payroll and related costs of $7.1 million, sales and marketing activities including cost of
free drug of $3.3 million, professional services including legal and accounting services of $1.0 million, medical education activities of $0.7 million and other general administrative activities of $0.3 million. The $9.6 million in selling, general
and administrative expenses recorded for the same period in 2007 was comprised primarily of payroll and related costs of $6.4 million, professional services including legal and accounting services of $1.6 million, sales and marketing activities
including cost of free drug of $1.4 million, and other general administrative activities including medical education activities of $0.2 million.

We expect total selling, general and administrative expenses to increase modestly for the remainder of 2008 compared to those recorded in the three-month period ended March 31, 2008.

Amortization of Intangible Assets

Amortization of intangible assets of $0.7 million in the three-month period ended March 31,
2008 represents expense recorded on a straight-line basis of milestone payments made to Ipsen and to Genentech in connection with the U.S. marketing approval of Somatuline® Depot and
marketing approval of Increlex® in the European Union, respectively. Refer to Ipsen Collaboration, under Liquidity and Capital Resources below for further
information on these milestone payments. We began amortization of these assets in November 2007 and expect to recognize the straight-line expense of $2.8 million annually through October 2022. There was no amortization of intangibles expense
recorded for the same period in 2007.

Interest Expense

Interest expense of $1.3 million for the three-month period ended March 31, 2008 increased $1.1 million over the same period in 2007. The increase in
2008 was primarily due to the timing of issuance of two convertible notes to Ipsen. The first convertible note was issued to Ipsen in October 2006. The second and third convertible notes were issued in September 2007.

We expect moderate increases in interest expense through October 2011, the remaining term on the convertible notes, as the stated interest rate of 2.5%
is applied to the outstanding balance of the convertible notes which includes the principal and accrued interest.

Other Income (Expense)

Other income of $2.0 million in the three-month period ended March, 31 2008 was largely due to a decrease in the fair value of the embedded derivative
conversion option related to a convertible note we issued to Ipsen in September 2007 partially offset by an unfavorable foreign currency adjustment. This convertible note is denominated in Euros and the conversion option is considered an embedded
derivative. The conversion option must be revalued at the end of each reporting period, which resulted in a benefit of $4.3 million in the first quarter of 2008. Further, this convertible note is revalued to U.S. dollars at the end of each reporting
period, which resulted in a charge of $2.4 million in the first quarter of 2008. There were no such charges recorded for the same period in 2007.

As currency rates, our stock price and our volatility assumptions change, we may record income or expense to Other Income (Expense) related to both the value of the note as well as the value of the embedded derivative. It is difficult to
forecast changes to Other Income (Expense) as we are unable to predict fluctuations in currency rates, our stock price and stock price volatility (see Part I, Item 3  Quantitative and Qualitative Disclosures about Market Risk
of this Form 10-Q).

Interest and Other Income, net

Net interest and other income, net of $1.1 million for the three-month period ended March 31, 2008 decreased $0.5 million compared to the same period
in 2007. The decrease was primarily due to interest income on lower average cash, cash equivalents and short-term investment balances during 2008 as well as lower interest rates. The lower cash balances in 2008 were primarily due to net cash used in
operations.

Assuming we do not raise additional funds during 2008, we expect net interest and other income to decrease for the remainder
of 2008 as we use cash and short-term investments to fund our operations.

Provision for income taxes

The provision for income taxes recorded in the three-month period ended March 31, 2008,
represents French foreign income taxes withheld on royalties paid to us by Ipsen under our Increlex® license and collaboration agreement with Ipsen. There were no income taxes withheld for
the same period in 2007 as Ipsen began selling Increlex® in the fourth quarter of 2007. We did not record domestic provisions for income taxes in the three-month periods ended
March 31, 2008 and 2007 because we have incurred operating losses to date.

Liquidity and Capital Resources

Sources of Liquidity

As of March 31, 2008, we had approximately $94.9 million in cash, cash equivalents and
short-term investments. We had an accumulated deficit of $306.7 million, which was primarily comprised of $262.6 million of accumulated net losses and $44.1 million of a non-cash deemed dividend related to the beneficial conversion feature of
convertible preferred stock. We have funded our operations and growth from inception through March 31, 2008 primarily from issuance of equity, convertible notes and the receipt of up-front and milestone payments under our collaboration with
Ipsen. To date we have received net cash proceeds of $283.2 million from equity issuances including equity sold to Ipsen and Genentech. We have issued three convertible notes to Ipsen from which we received net cash proceeds of $15.0 million, net of
the balance which was used to make milestone payments to Ipsen related to the Somatuline® license and collaboration agreement. In addition, we have received $31.7 million from Ipsen, net of
withholding taxes, for milestone payments related to the Increlex® license and collaboration agreement.

Ipsen Collaboration

On
October 13, 2006, we completed the initial closing of the transactions contemplated by the stock purchase and master transaction agreement we entered into with Ipsen in July 2006. At the closing, we issued 12,527,245 shares of our common stock
to an affiliate of Ipsen for an aggregate purchase price of $77.3 million and issued to Ipsen a convertible note in the principal amount of $25.0 million and a warrant to purchase a minimum of 4,948,795 shares of our common stock, which warrant is
exercisable at any time during the five-year period after the initial closing and carries an initial exercise price equal to $7.41 per share. Under the stock purchase and master transaction agreement with Ipsen, we issued a second convertible note
and a third convertible note to Ipsen in connection with our Somatuline® license and collaboration agreement as described below. Each of the convertible notes that we issued to Ipsen
matures on the later of October 13, 2011 or two years from the date of notification of non-convert and carries a coupon of 2.5% per annum from the date of issuance, compounded quarterly, and is convertible into shares of our common stock
at an initial conversion price per share equal to $7.41 per share (or 5.92 per share with respect to the second convertible note). Together with the 13,046,346 shares of our common stock that we have issued to Ipsen (and/or an affiliate
of Ipsen) to date, the conversion of all three convertible notes and the exercise of the warrant in full would enable Ipsen to acquire an ownership interest in us of approximately 40% on a fully diluted basis.

##### Table of Contents

Pursuant to the licensing agreements we entered
into with Ipsen (and/or affiliates thereof) in connection with the initial closing under the stock purchase and master transaction agreement, we granted to Ipsen and its affiliates exclusive rights to develop and commercialize Increlex® in all countries of the world except the United States, Japan, Canada, and for a certain period of time, Taiwan and certain countries of the Middle East and North Africa, and Ipsen granted to
us exclusive rights to develop and commercialize Somatuline® Depot in the United States and Canada. Further, we and Ipsen granted to each other product development rights and agreed to
share the costs for improvements to, or new indications for, Somatuline® Depot and Increlex®. In addition, we and Ipsen agreed to
rights of first negotiation for our respective endocrine pipelines. In August 2007, the European Commission granted marketing authorization for Increlex® in the European Union for the
long-term treatment of growth failure in children and adolescents with severe Primary IGFD. Under the license and collaboration agreement with respect to Increlex®, Ipsen made an upfront
cash payment to us of 9.5 million, or $11.8 million, after tax withholding in October 2006, and paid us an additional milestone of approximately of 14.3 million, or $19.3 million, after tax withholding, in September 2007 for
receiving marketing authorization for Increlex® in the European Union for the targeted product label. Ipsen is our marketing partner for Increlex® in the European Union. In November 2007, Increlex® was launched by Ipsen in Ipsens territory. We are entitled to royalties on Increlex® sales made in Ipsens territory on a sliding scale from 15% to 25% of the average net sales price, in addition to a supply price of 20% of net sales of Increlex®.

Under the license and collaboration agreement
with respect to Somatuline® Depot, we made an upfront payment of $25.0 million to Ipsen in October 2006, which was financed through the issuance by us of the first convertible note to Ipsen
at the initial closing under the stock purchase and master transaction agreement. In August 2007, we received marketing approval for Somatuline® Depot in the United States for the targeted
product label (and the second closing under the stock purchase and master transaction agreement was consummated). Following receipt of the marketing approval, we made a milestone payment of 30.0 million, or $41.6 million, to Ipsen, which
was financed through the issuance by us of the second convertible note to Ipsen at the second closing. The milestone payment was capitalized as an intangible asset and will be amortized over the useful life of the asset. At the second closing, we
also issued the third convertible note to Ipsen and Ipsen delivered $15.0 million to us, which will be used by us for working capital. We launched Somatuline® Depot in the United States in
November 2007. We pay royalties to Ipsen, on a sliding scale from 15% to 25% of net sales, in addition to a supply price of 20% of the average net sales price of Somatuline® Depot.

There can be no assurance that we will achieve the anticipated benefits of our collaboration with Ipsen. Further, we would be required to
pay to Ipsen the principal amounts, including accrued interest, under all three convertible notes that we issued to Ipsen if Ipsen elects not to convert these notes into shares of our common stock. For more information on these and other risks and
uncertainties related to our collaboration with Ipsen, see the sections entitled Risks Related to Our Business and Risks Related to Our Common Stock under Part II, Item 1A below.

Genentech Combination Product Collaboration

Effective as of July 6, 2007, we and Genentech entered into a combination product development
and commercialization agreement which governs the worldwide development and commercialization of two combination product candidates containing Genentechs rhGH, Nutropin AQ®, and our
rhIGF-1, Increlex®, for the treatment of all indications except those of the central nervous system. Initially, we will be responsible for the development and commercialization of all
combination product candidates under the combination product agreement and have agreed to pay Genentech a royalty on net sales of combination products covered by Genentechs (or the parties joint) patents, subject to certain opt in rights
granted to Genentech as described in Note 8, Combination Product Development and Commercialization Agreement in the Notes to Financial Statements of Part II, Item 8 of the Form 10-K filed for the year ended December 31, 2007.
Upon opting in, Genentech would become obligated to reimburse us for a portion of the development costs incurred since July 9, 2007, and thereafter we and Genentech would share future costs and all operating profits and losses, and no royalties
will be owed to Genentech. Genentech would receive such profit share in lieu of its royalty payment. Under the combination product agreement, we may receive a cash milestone payment in certain circumstances and we may be entitled to royalties on net
sales of certain combination products. In addition, we issued 708,591 shares of common stock to Genentech at price per share of $5.645 pursuant to a stock purchase agreement we entered into with Genentech, resulting in gross cash proceeds of
approximately $4.0 million, and we may issue up to an additional 1,894,737 shares of common stock (or up to a maximum of $9.0 million of shares of common stock) to Genentech pursuant to the stock purchase agreement. However, there can be no
assurance that we will receive all or any remaining portion of the anticipated proceeds, including the reimbursement of development costs, the cash milestone payment and additional proceeds from the sale of shares of our common stock to Genentech,
nor can there be an assurance that we would achieve the anticipated benefits of our combination product agreement with Genentech. Further, we must first obtain Ipsens approval to issue shares of common stock to Genentech under the stock
purchase agreement at a price per share less than $4.75 and if we do issue shares to Genentech under the stock purchase agreement at a price per share less than $4.75, such issuance would trigger certain weighted-average price-based antidilution
adjustments to the convertible notes and warrant we issued to Ipsen. Please refer to Note 8, Combination Product Development and Commercialization Agreement, in the Notes to Financial Statements of the Form 10-K filed for the year ended
December 31, 2007 for more detail on the terms of the combination product agreement and stock purchase agreement.

Committed Equity Financing Facility

Under the terms of a committed equity financing facility, or CEFF, we entered into with Kingsbridge Capital Limited, or Kingsbridge, Kingsbridge committed
to purchase a maximum of approximately 6,000,000 newly issued shares of our common stock over a three-year period beginning in October 2005, for cash up to an aggregate of $75.0 million, subject to certain conditions. We may draw down under the CEFF
in tranches of up to the lesser of $7.0 million or 2% of our market capitalization at the time of the draw down of such tranche, subject to certain conditions. The common stock to be issued for each draw down will be issued and priced over an
eight-day pricing period at discounts ranging from 6% to 10% from the volume weighted average price of our common stock during the pricing period. During the term of the CEFF, Kingsbridge may not short our stock, nor may it enter into any derivative
transaction directly related to our stock. The minimum acceptable purchase price, prior to the application of the appropriate discount for any shares to be sold to Kingsbridge during the eight-day pricing period, is determined by the greater of
$3.00 or 90% of our closing share price on the trading day immediately prior to the commencement of each draw down. In connection with the CEFF, we issued a warrant to Kingsbridge to purchase up to 260,000 shares of our common stock at an exercise
price of $13.12 per share. We intend to exercise our right to draw down amounts under the CEFF, if and to the extent available, at such times as we have a need for additional capital and when we believe that sales of our common stock under the CEFF
provide an appropriate means of raising capital. However, we are not obligated to sell any of the $75.0 million of common stock available under the CEFF, and there are no minimum commitments or minimum use penalties. Under the terms of an
affiliation agreement we entered into pursuant to our collaboration with Ipsen, we have only a limited ability to raise capital through the sale of our equity securities, including pursuant to the CEFF, without first obtaining Ipsens approval.

Cash, cash equivalents and short-term investments totaled $94.9 million at March 31, 2008,
compared to $113.5 million at December 31, 2007. The net decrease in cash, cash equivalents and short-term investments in 2008 was primarily due to cash used in operating activities of $19.0 million offset by cash provided by net sales of
short-term investments as discussed below.

Operating Activities

Net cash used in operating activities totaled $19.0 million in the three-month period ended
March 31, 2008. Cash used in operating activities during 2008 was primarily driven by our net losses from operations of $17.5 million, increase in inventory of $4.8 million, adjusted for the non-cash compensation charge of $1.5 million related
to SFAS No. 123R and a net non-cash income of $1.3 million related to the Euro-denominated convertible note we issued to Ipsen. The increase in inventories was primarily due to the manufacture of Increlex® and purchases of Somatuline® Depot that were partially funded by an increase in accrued expenses.

Investing Activities

Net cash
provided by investing activities totaled $12.3 million in the three-month period ended March 31, 2008. Cash provided by investing activities represented net proceeds from purchase, sales and maturities of investments.

Financing Activities

Net cash
provided by financing activities totaled $0.2 million in the three-month period ended March 31, 2008. Cash provided by financing activities was primarily due to issuances of common stock under our equity compensation plans.

We expect capital outlays and operating expenditures to increase over the next several years as we expand
our operations. We believe that our cash, cash equivalents and short-term investments as of March 31, 2008 will be sufficient to meet our projected operating and capital expenditure requirements through at least March 31, 2009 based on our
current business plan. However, our future capital needs and the adequacy of our available funds will depend on many factors, including:



| |  |  | changes to our business plan;
| | - |  | -----------------------------



| |  |  | our ability to market and sell sufficient quantities of Increlex® and Somatuline® Depot at the anticipated level;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | the commercial status of the Increlex® bulk drug
manufacturing operations at Lonza Baltimore Inc. and Lonza Hopkinton Inc., including the success of our cGMP production activities;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the success of Increlex® final drug product manufacturing;
| | - |  | ----------------------------------------------------------



| |  |  | the costs, timing and scope of additional regulatory approvals for Increlex®use in Primary IGFD and/or other regions;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | Ipsens ability to supply Somatuline® Depot to us in
sufficient quantities;
| | - |  | ---------------------------------------------------------------------------



| |  |  | the costs, timing and scope of additional regulatory approvals for Somatuline® Depot;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | Ipsens ability to market and sell sufficient quantities of Increlex® in the licensed territories at the anticipated level;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | any required repayment of the convertible notes we issued to Ipsen;
| | - |  | -------------------------------------------------------------------



| |  |  | the status of competing products;
| | - |  | ---------------------------------



| |  |  | the rate of progress and cost of our future clinical trials and other research and development activities, including research and development activities and
clinical trial costs in connection with our growth hormone/IGF-1 combination product candidates; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the pace of expansion of administrative and legal expenses.
| | - |  | -----------------------------------------------------------

Due to the significant risks and uncertainties inherent in the manufacturing, clinical development and regulatory approval processes, the costs to complete our projects through product commercialization are not
accurately predictable. Results from regulatory review, manufacturing operations and clinical trials may not be favorable. Further, data from clinical trials is subject to varying interpretation, and may be deemed insufficient by the regulatory
bodies reviewing applications for marketing approvals. As such, our development projects are subject to risks, uncertainties and changes that may significantly impact cost projections and timelines. As a result, our capital requirements may increase
in future periods.

We expect that we will require and will attempt to raise additional funds through equity or debt financings,
collaborative arrangements with corporate partners or from other sources, including potentially the CEFF. However, there can be no assurance that additional financing will be available when needed, or, if available, that the terms will be favorable.
In addition, under the terms of an affiliation agreement we entered into pursuant to our collaboration with Ipsen, we have only a limited ability to raise capital through the sale of our equity without first obtaining Ipsens approval. Although
we have entered into a stock purchase agreement with Genentech pursuant to which we may issue up to an additional 1,894,737 shares of common stock (or up to a maximum of $9.0 million of shares of common stock) to Genentech, such issuances are
subject to various conditions, including a Genentech opt in and the achievement of a regulatory approval milestone, and there can be no assurance that we will receive additional funds from Genentech pursuant to the stock purchase agreement. If
additional funds are not available, we may be forced to curtail or cease operations.

Contractual Obligations and Commercial
Commitments

During the three-month period ended March 31, 2008, there were no material changes to our contractual obligation
and commercial commitment disclosures as set forth under the caption, Contractual Obligations and Commercial Commitments in Part II, Item 7, Managements Discussion and Analysis of Financial Condition and Results of
Operations, of our Annual Report on Form 10-K for the year ended December 31, 2007.



|ITEM 3. | QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
|------- | ----------------------------------------------------------

The primary objective of our investment activities is to preserve our capital for the purpose of funding operations while at the same time maximizing the income we receive from our investments without significantly increasing risk. To
achieve these objectives, our investment policy allows us to maintain a portfolio of cash equivalents and short-term investments in a variety of securities, including asset-backed securities, commercial paper, corporate bonds, government sponsored
entity bonds and money market funds.



27

##### Table of Contents

Interest Rate Risk

As of March 31, 2008, we held $65.9 million in cash and cash equivalents consisting of highly liquid investments having original maturity dates of
less than 90 days. Declines of interest rates over time would reduce our interest income from our highly liquid short-term investments. Based upon our balance of cash and cash equivalents, a decrease in interest rates of 100 basis points would cause
a corresponding decrease in our annual interest income of approximately $0.7 million for these investments. Due to the nature of our highly liquid cash equivalents, a change in interest rates would not materially change the fair market value of our
cash and cash equivalents.

As of March 31, 2008, we held $29.0 million in short-term investments, which consisted primarily of money
market funds held by large institutions in the United States, federal agency bonds, commercial paper, corporate bonds and asset-backed securities maturing in less than twelve months. The weighted average interest rate of our investments held was
approximately 4.2% during the three-month period ended March 31, 2008. A decline in interest rates over time would reduce our interest income from our short-term investments. A decrease in interest rates of 100 basis points would cause a
corresponding decrease in our annual interest income of approximately $0.3 million for these investments. Due to the nature of our highly liquid cash equivalents, a change in interest rates would not materially change the fair market value of our
short-term investments.

Foreign Currency Exchange Risk

The Euro-denominated convertible note we issued to Ipsen was recorded at 22.2 million or approximately $35.0 million, net of discount and
including accrued interest, at March 31, 2008. The face value of the note is 30.0 million plus accrued interest of 0.4 million and the discount of 8.2 million will be accreted over the life of the convertible
note. The convertible note accrues interest at a rate of 2.5% per year, compounded quarterly until maturity in October 2011. As currency rates change, the net recorded value of the convertible note (which will also be increasing in value due to
the accretion of the discount and accrued interest) will be revalued, and the corresponding translation adjustment will be recorded in the statements of operations. A hypothetical change of 10% in currency rates could result in an adjustment to the
consolidated statements of operations of approximately $3.5 million. Upon maturity of the convertible note in October 2011, if the holder of the note chooses to not convert, we would be required to repay the convertible note of
33.2 million which includes accrued interest. A hypothetical change of 10% in currency rates could result in our paying $5.2 million more or less in cash than anticipated upon issuance of the convertible note.

Associated with the issuance of this convertible note to Ipsen, we recorded a derivative liability due to a conversion option denominated in a foreign
currency. The terms of the convertible note include a conversion option not under our control. This conversion option is considered to be an embedded derivative liability and we determined the fair value of this derivative to be
9.2 million or approximately $12.8 million on the date of issuance, September 17, 2007. Due to the quarterly revaluation of the embedded derivative liability and due to foreign currency revaluation, we recorded in our statements of
operations other income of $2.0 million for the quarter ended March 31, 2008. At March 31, 2008, the embedded derivative liability was valued at 6.2 million or approximately $9.8 million. We determine the fair value of the
derivative liability using the Black-Scholes-Merton valuation model. The valuations are based on the information available as of the various valuation dates. Factors affecting the amount of this liability include the market value of our common
stock, the conversion price of note, volatility of our common stock, the expected life, the Euro to U.S. dollar currency exchange rate and the risk-free interest rate. A change in the market value of our common stock could have a significant impact
on the results of our operations; however, there would not be any impact on our cash flows. A hypothetical change of 10% in currency rates could result in an adjustment to the statements of operations of approximately $1.0 million.



|ITEM 4. | CONTROLS AND PROCEDURES.
|------- | ------------------------

Evaluation of
Disclosure Controls and Procedures

Based on their evaluation as of March 31, 2008, our Chief Executive Officer and Chief
Financial Officer, with the participation of our management, have concluded that our disclosure controls and procedures (as defined in Rules 13a15(e) and 15d15(e) of the Securities Exchange Act of 1934) were effective.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended March 31, 2008 that have materially affected, or are reasonably likely to materially affect, our internal control
over financial reporting.

Limitations on the Effectiveness of Controls

Our disclosure controls and procedures provide our Chief Executive Officer and Chief Financial Officer reasonable assurances that our disclosure controls
and procedures will achieve their objectives. However, company management, including our Chief Executive Officer and Chief Financial Officer, does not expect that our disclosure controls and

##### Table of Contents

procedures or our internal control over financial reporting can or will prevent all human error. A control system, no matter how well designed and
implemented, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Furthermore, the design of a control system must reflect the fact that there are internal resource constraints, and the benefit of
controls must be weighed relative to their corresponding costs. Because of the limitations in all control systems, no evaluation of controls can provide complete assurance that all control issues and instances of error, if any, within our company
are detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur due to human error or mistake. Additionally, controls, no matter how well designed, could be circumvented
by the individual acts of specific persons within the organization. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed
in achieving its stated objectives under all potential future conditions.

PART II  OTHER INFORMATION



|ITEM 1A. | RISK FACTORS.
|-------- | -------------

We have identified the following
additional risks and uncertainties that may have a material adverse effect on our business, financial condition or results of operations. Investors should carefully consider the risks described below before making an investment decision. The risks
described below are not the only ones we face. Additional risks not presently known to us or that we currently believe are immaterial may also significantly impair our business operations. Our business could be harmed by any of these risks. The
trading price of our common stock could decline due to any of these risks, and investors may lose all or part of their investment.

We have marked with an asterisk (*) those risks described below that reflect substantive changes from the risks described under Item 1A. Risk Factors included in our Annual Report on Form 10-K filed with the Securities
and Exchange Commission on February 29, 2008.

Risks Related to Our Business

We have a limited operating history and may not be able to successfully market and sell products, generate significant revenues or attain
profitability.*

We have a limited operating history. Through March 31,
2008, we had an accumulated deficit of $306.7 million. We incurred a net loss of $17.5 million during the quarter ended March 31, 2008. We may not be able to generate significant revenues from operations and may not be able to attain
profitability. We expect to incur substantial net losses, in the aggregate and on a per share basis, for the foreseeable future as we attempt to develop, market and sell Increlex® for
severe Primary IGFD and Primary IGFD and Somatuline® Depot for acromegaly, and as we attempt to develop growth hormone/IGF-1 combination product candidates under our Combination Product
Agreement with Genentech. We are unable to predict the extent of these future net losses, or when we may attain profitability, if at all. These net losses, among other things, have had and will continue to have an adverse effect on our
stockholders equity and net current assets.

We anticipate that for the
foreseeable future our ability to generate revenues and achieve profitability will be dependent on the successful commercialization by us and Ipsen of Increlex® for the treatment of severe
Primary IGFD and Primary IGFD, as well as on the successful commercialization by us of Somatuline® Depot for acromegaly in the United States and Canada. There is no assurance that we will
be able to obtain or maintain governmental regulatory approvals to market our products in the United States or rest of the world for these or any other indications. If we are unable to generate significant revenue from Increlex® or Somatuline® Depot, or attain profitability, we will not be able to sustain our operations.

If there are fewer children with severe Primary IGFD or Primary IGFD than we estimate, our ability
to generate revenues sufficient to fund our development and commercialization efforts may be curtailed.

We estimate that the number
of children in the United States with short stature is approximately 1,000,000, of which approximately 380,000 are referred to pediatric endocrinologists for evaluation. We believe that approximately 30,000 of these children have Primary IGFD, of
which approximately 6,000 have severe Primary IGFD. Our estimate of the size of the patient population is based on published studies as well as internal data, including our interpretation of a study conducted as part of Genentechs National
Cooperative Growth Study program. This study reported results of the evaluation of the hormonal basis of short stature in approximately 6,450 children referred to pediatric endocrinologists over a four-year period. We believe that the aggregate
numbers of children in Western Europe with Primary IGFD and severe Primary IGFD are substantially equivalent to the numbers in the United States. If the results of Genentechs study or our interpretation and extrapolation of data from the study
do not accurately reflect the number of children with Primary IGFD or severe Primary IGFD, our assessment of the market may be incorrect, making it difficult or impossible for us to meet our revenue goals or to receive royalties from our
collaboration with Ipsen to the extent that we currently anticipate.

Our products may fail to achieve market acceptance, which could
harm our business.

Prior to our January 2006 commercial launch of
Increlex® in the United States for the treatment of severe Primary IGFD, rhIGF-1 had never been commercialized in the United States or Europe for any indication. Even though the FDA has
approved Increlex® for sale in the United States, and Somatuline® Depot has received marketing approval in Canada and the United
States, physicians may choose not to prescribe these products, and third-party payers may choose not to pay for them. Accordingly, we may be unable to generate significant revenue or become profitable.

Acceptance of our products will depend on a number of factors including:



| |  |  | acceptance of our products by physicians and patients as safe and effective treatments;
| | - |  | ---------------------------------------------------------------------------------------



| |  |  | reimbursement adoption;
| | - |  | -----------------------



| |  |  | product price;
| | - |  | --------------



| |  |  | the effectiveness of our and collaboration partners sales and marketing efforts;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | storage requirements and ease of administration;
| | - |  | ------------------------------------------------



| |  |  | dosing regimen;
| | - |  | ---------------



| |  |  | safety and efficacy;
| | - |  | --------------------



| |  |  | prevalence and severity of side effects; and
| | - |  | --------------------------------------------



| |  |  | competitive products.
| | - |  | ---------------------

If we do not receive additional regulatory marketing approvals for Increlex® in Primary IGFD, our business will be harmed.

We are currently developing Increlex® for the treatment of Primary IGFD. The FDA has substantial discretion in the approval process and may decide that the
data from our clinical trial is insufficient to allow approval of Increlex® for Primary IGFD. If we do not receive regulatory marketing approval in the United States for Primary IGFD, our
business will be harmed. We will also need to file applications with regulatory authorities in foreign countries to market Increlex® for Primary IGFD. There is no assurance that we will
receive marketing approvals in any foreign countries for Primary IGFD.

We may not realize the anticipated benefits from our
collaboration with Ipsen.

Even though Somatuline® Depot has received marketing approval from the FDA, the approval may not be maintained. We may also elect not to, or we may be unable to develop or obtain FDA approval of Somatuline® Depot for indications other than acromegaly, such as neuroendocrine tumors. Further, Ipsen may be unable to maintain the supply of the product. In addition, revenues from sales of Somatuline® Depot in the United States and Canada may not meet our expectations, including as a result of competing products or unavailable or limited reimbursement by third-party payers. Under the license
and collaboration agreement with respect to Somatuline® Depot, Ipsen may terminate the agreement in a particular country if we fail to meet certain minimum sales and promotional
requirements with respect to that country. It is also possible that Ipsen will not be successful in marketing and selling Increlex® in the licensed territories, or may be delayed in doing
so, in which case we would not receive royalties on the timeframe and to the extent that we currently anticipate. We also may not be able to successfully develop additional products or improvements to, or new indications for, Somatuline® Depot and/or Increlex® or share the costs of such developments in a manner that is commercially feasible for us. In addition to
cross-licensing agreements for Somatuline® Depot and Increlex®, we and Ipsen have granted to each other a right of first
negotiation for

products in our respective endocrine pipelines and have agreed on a framework for joint clinical development and subsequent commercialization of endocrine
products on a worldwide basis. However, the development of Ipsens endocrine pipeline may not advance at the rate we currently expect, or at all, and in any event, we cannot assure you that we will be able to reach an agreement with Ipsen on
reasonable terms, or at all, for any of these endocrine pipeline products. The license and collaboration agreements would also be terminable by Ipsen under certain circumstances, including certain change of control transactions. In any such or
similar events, we may not realize the anticipated benefits from our collaboration with Ipsen.

There can be no assurance that we will
receive all or any remaining portion of the anticipated proceeds from our collaboration with Ipsen, nor can there be an assurance that we would achieve the anticipated benefits of our collaboration with Ipsen. Further, we would be required to pay to
Ipsen the principal amounts, including accrued interest, under all three convertible notes that we issued to Ipsen if Ipsen (or subsequent holders of the notes) elects not to convert these notes into shares of our common stock.

We may not realize the anticipated benefits from our growth hormone/IGF-1 combination product candidates or from the related agreement with
Genentech.

Our two growth hormone/IGF-1 combination product candidates may not enter clinical trials or receive U.S. or other
countries regulatory approval, in a timely manner, for the labels that we anticipate, or at all. We may encounter development difficulties that delay, increase the costs of, or preclude any further progress of either or both of our growth
hormone/IGF-1 combination product candidates. In addition, the FDA and other countries regulatory authorities have substantial discretion in the approval process. They may decide that our pre-clinical data, chemistry, manufacturing and
controls data, and/or clinical data are insufficient to warrant timely, or any, entry into Phase I, Phase II or Phase III clinical trials, and/or that the data from our Phase III clinical trials are insufficient to allow marketing approval of our
growth hormone/IGF-1 combination product candidates for their target labels. If we do not receive regulatory marketing approvals for the target labels, our business will be harmed.

Even if our combination product candidates were to receive such regulatory marketing approvals, the approvals may not be maintained. In addition,
revenues from worldwide sales of these two product candidates may not meet our expectations, including, as a result of competing products or unavailable or limited reimbursement by third-party payers. We also may not be able to successfully develop
improvements to, or new indications for, our combination product candidates or receive financial consideration from sub-licensees in a manner that is commercially feasible for us. In connection with our agreement with Genentech for our combination
product candidates, Genentech may opt into the programs and obtain a share of the financial benefit going forward. In any such or similar events, we may not realize the anticipated benefits from our combination product candidates. There can be no
assurance that we will receive all or any remaining portion of the anticipated proceeds from our agreement with Genentech, nor can there be an assurance that we would achieve the anticipated benefits from our agreement with Genentech.

Clinical development is a long, expensive and uncertain process, and delay or failure can occur at any stage of any of our clinical trials.

To gain approval to market a product for treatment of a specific disease, we must provide the FDA and foreign regulatory
authorities with clinical data that demonstrate the safety and statistically significant efficacy of that product for the treatment of the disease. Clinical development is a long, expensive and uncertain process, and delay or failure can occur at
any stage of any of our clinical trials. For example, we are seeking to develop our growth hormone/IGF-1 combination product candidates for short stature, AGHD, and potentially other metabolic disorders, but we may determine that such trials are
prohibitively expensive and ultimately may not proceed with such trials. A number of companies in the pharmaceutical industry, including biotechnology companies, have suffered significant setbacks in advanced clinical trials, even after promising
results in earlier trials. Success in pre-clinical testing or in early clinical trials does not ensure that later clinical trials will be successful. If a clinical trial failed to demonstrate safety and statistically significant efficacy, we would
likely abandon the development of that product, which could harm our business.

We do not know whether our planned clinical trials
will begin on time, or at all, or will be completed on schedule, or at all.*

The commencement or completion of any of our clinical
trials may be delayed or halted for numerous reasons, including, but not limited to, the following:



| |  |  | the FDA or other regulatory authorities do not approve an investigational new drug application or a clinical trial protocol, or they place a clinical trial on
clinical hold;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | patients do not enroll in clinical trials at the rate we expect or they withdraw at a greater rate than expected;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | patients experience adverse side effects;
| | - |  | -----------------------------------------

| |  |  | patients develop medical problems that are not related to our products or product candidates;
| | - |  | ---------------------------------------------------------------------------------------------



| |  |  | third-party clinical investigators do not perform our clinical trials on our anticipated schedule or consistent with the clinical trial protocol and good clinical
practices, or other third-party organizations do not perform data collection and analysis in a timely or accurate manner;

| | - |  | ------------------------------------------------------------------------------------------------------



| |  |  | interim results of the clinical trial are inconclusive or negative;
| | - |  | -------------------------------------------------------------------



| |  |  | clinical trial drug supplies may not be available, may not be available in sufficient quantities, may not be available in the preferred formulation, or available
drug may become unusable;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our trial design, although approved, is inadequate to demonstrate safety and/or efficacy;
| | - |  | -----------------------------------------------------------------------------------------



| |  |  | re-evaluation of our corporate strategies and priorities;
| | - |  | ---------------------------------------------------------



| |  |  | limited financial resources.
| | - |  | ----------------------------

In
addition, we may choose to cancel, change or delay certain planned clinical trials, or replace one or more planned clinical trials with alternative clinical trials. Our clinical trials or intended clinical trials may be subject to further change
from time-to-time as we evaluate our research and development priorities and available resources. Our development costs will increase if we need to perform more or larger clinical trials than planned. Significant delays for our current or planned
clinical trials may harm the commercial prospects for our products.

Reimbursement for our products may be slow, not available at the
levels we expect, or not available at all, resulting in our expected revenues being delayed or substantially reduced.

Market acceptance, our sales of Increlex® and Somatuline® Depot , and our profitability will depend on reimbursement policies and health care reform measures. The levels at which government
authorities and third-party payers, such as private health insurers and health maintenance organizations, reimburse the price patients pay for our products, and the timing of reimbursement decisions by these payers, will affect the commercialization
of our products. If our assumptions regarding the timing of reimbursement decisions and level of reimbursement, or regarding the age, dosage or price per patient for Increlex® are
incorrect, our expected revenues, including potential royalties from our collaboration with Ipsen, may be delayed or substantially reduced. Since Increlex® is approved by the FDA for severe
Primary IGFD and Somatuline® Depot is approved by the FDA for the treatment of acromegaly, only prescriptions for those indications may be reimbursable. Also, we cannot be certain that the
formulary status our products ultimately receive by payers will not limit the ability of patients to afford our products and therefore reduce the demand for, or the price of, our products. If reimbursement is not available or is available only to
limited levels, we may not be able to market and sell our products and our revenues may be delayed or substantially reduced. Even if a patient receives reimbursement approval, the patient may still choose not to begin, or to discontinue, treatment
with either of our drugs.

We believe that the annual wholesale acquisition cost, at
present, of Increlex® therapy for the treatment of severe Primary IGFD for a 24 kilogram child at a 120mcg/kg twice daily dose at 100% compliance is approximately $36,000 per year. The
actual cost per year per patient for Increlex® will depend on the price charged by wholesalers and distributors that purchase from Tercica, and will vary by the weight of the child, the
treatment dose prescribed and the level of compliance. If our assumptions regarding the revenue per patient of Increlex® therapy for the treatment of severe Primary IGFD and Primary IGFD
are incorrect, our expected revenues and the market opportunity for Increlex® therapy for the treatment of severe Primary IGFD and Primary IGFD may be substantially reduced.

We believe that the annual wholesale acquisition cost, at present, of Somatuline® Depot therapy for the treatment of acromegaly is approximately $28,800 at 100% compliance of the 90 microgram dose. The actual cost per year will depend on the price charged by wholesalers and
distributors that purchase from Tercica, and will vary by the treatment dose prescribed and the level of compliance. If our assumptions regarding the average treatment dose per patients or revenue per patient for the treatment of acromegaly are
incorrect, our expected revenues and the market opportunity for Somatuline® Depot for the treatment of acromegaly may be substantially reduced.

In recent years, officials have made numerous proposals to change the health care system in the United States. These proposals include measures that
would limit or prohibit payments for certain medical treatments or subject the pricing of drugs to government control. In addition, in many foreign countries, particularly in Canada and the countries of the European Union, the pricing of
prescription drugs is subject to government control. If our products become subject to government legislation that limits or prohibits payment for our products, or that subjects the price of our products to governmental control, we may not be able
to generate revenues, attain profitability or market and sell our products. Because these initiatives are subject to substantial political debate, which we cannot predict, the trading price of biotechnology stocks, including ours, may become more
volatile as this debate proceeds.

As a result of legislative proposals and the trend towards managed health care in the United States,
third-party payers are increasingly attempting to contain health care costs by limiting both coverage and the level of reimbursement of new drugs. They may also refuse to provide any coverage of uses of approved products for medical indications
other than those for which the FDA has granted market approvals, or require patients to pay co-insurance for our products. As a result, significant uncertainty exists as to whether and how much third-party payers will reimburse patients for their
use of newly approved drugs, which, in turn, could put pressure on the pricing of drugs and/or the adoption of new products based on reimbursement policies.

We are dependent on our collaboration with Ipsen for the development and commercialization
of Increlex® outside of the United States, Canada and Japan, and for a certain period of time, certain countries of the Middle East and North Africa and Taiwan. We may also be
dependent upon additional collaborative arrangements in the future. These collaborative arrangements may place the development and commercialization of our product candidates outside of our control, may require us to relinquish important rights or
may otherwise be on terms unfavorable to us.

Under the terms of our
collaboration with Ipsen, we granted Ipsen the exclusive right to develop and commercialize Increlex® in all regions of the world except the United States, Japan, and Canada, and for a
certain period of time, certain countries of the Middle East and North Africa and Taiwan. We may also enter into additional collaborations with third parties to develop and commercialize our product candidates such as our agreement with Genentech
for our growth hormone/IGF-1 combination product candidates. Dependence on collaborators for the development and commercialization of our product candidates subjects us to a number of risks, including:



| |  |  | we may not be able to control the amount and timing of resources that our collaborators devote to the development or commercialization of product candidates or to
their marketing and distribution, which could adversely affect our ability to obtain milestone and royalty payments;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | collaborators may delay clinical trials, provide insufficient funding for a clinical trial program, stop a clinical trial or abandon a product candidate, repeat or
conduct new clinical trials or require a new formulation of a product candidate for clinical testing;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | disputes may arise between us and our collaborators that result in the delay or termination of the research, development or commercialization of our product
candidates or that result in costly litigation or arbitration that diverts managements attention and resources;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | our collaborators may experience financial difficulties;
| | - |  | --------------------------------------------------------



| |  |  | collaborators may not properly maintain or defend our intellectual property rights or may use our proprietary information in such a way as to expose us to potential
litigation, jeopardize or lessen the value of our proprietary information, or weaken or destroy our intellectual property rights;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | business combinations or significant changes in a collaborators business strategy may also adversely affect a collaborators willingness or ability to
complete its obligations under any arrangement;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | a collaborator could independently move forward with a competing product candidate developed either independently or in collaboration with others, including our
competitors; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

We face significant competition from large pharmaceutical, biotechnology and other companies that could harm our business.

The biotechnology industry is intensely competitive and characterized by rapid technological progress. In each of our potential product areas, we face
significant competition from large pharmaceutical, biotechnology and other companies. Most of these companies have substantially greater capital resources, research and development staffs, facilities and experience at conducting clinical trials and
obtaining regulatory approvals. In addition, many of these companies have greater experience, expertise and resources in developing and commercializing products.

We cannot predict the relative competitive positions of Increlex®, Somatuline® Depot and any growth hormone/IGF-1 combination product candidates that we may develop. However, we expect that the factors set forth
underRisks Related to Our BusinessOur products may fail to achieve market acceptance, which could harm our business, among others, including manufacturing cost containment, will determine our ability to compete effectively.

##### Table of Contents

Many of our competitors spend significantly more on research and development-related activities than we
do. Our competitors may discover new treatments, drugs or therapies or develop existing technologies to compete with our products. Our commercial opportunities will be reduced or eliminated if these competing products are more effective, have fewer
or less severe side effects, are more convenient or are less expensive than our products.

Growth hormone products compete with Increlex® for the treatment of severe Primary IGFD. If Increlex® receives
regulatory approval for the treatment of patients with Primary IGFD, growth hormone products will also compete with Increlex® for the treatment of patients in that indication. The major
suppliers of commercially available growth hormone products in the United States are Genentech Inc., Eli Lilly and Company, Teva Pharmaceutical Industries Ltd., Novo Nordisk A/S, Pfizer Inc and Merck-Serono International S.A. Investigators from a
Novo Nordisk clinical trial in 2003 presented initial data that demonstrated growth hormone was effective in a population that included children with Primary IGFD.

In addition, children with Primary IGFD may be diagnosed as having idiopathic short stature, or
ISS. Eli Lilly and Genentech have received FDA approval for their respective growth hormone products for the treatment of children with ISS in the United States. Moreover, biosimilar growth hormone products, including Omnitrope marketed by Sandoz, Accretropin by Cangene, and Valtropin® by LG Life
Sciences have been approved in the United States and may be approved in other countries. Accordingly, we expect that several growth hormone products will compete directly with Increlex® for
the treatment of children with Primary IGFD. We are also aware that several companies are developing long-acting formulations of growth hormone for the treatment of short stature including Altus Pharmaceuticals and LG Life Sciences.

In addition, we are aware that Novartis AG has developed a process to manufacture rhIGF-1 using
yeast expression and has intellectual property with respect to that process. We use bacterial expression, which differs from yeast expression, to manufacture Increlex®.

We believe that Bristol-Myers Squibb Company; Genentech; Merck & Co., Inc.; Novo Nordisk
and Pfizer have conducted research and development of orally available small molecules that cause the release of growth hormone, known as growth hormone secretagogues. We believe that Sapphire Therapeutics, Inc. has licensed certain rights to Novo
Nordisks growth hormone secretagogues and that Elixir Pharmaceuticals Inc. has licensed certain rights to Bristol-Myers Squibb Companys growth hormone secretagogues and that both companies are actively developing these compounds for use
in various indications including cancer cachexia, a wasting disorder affecting some cancer patients. These products work by increasing the levels of rhIGF-1 and, if approved, could potentially compete with Increlex®.

If our growth hormone/IGF-1 combination products
are approved for commercial sale, they would compete across all their approved indications with all then existing, biosimilar and long acting growth hormone products, growth hormone secretagogue products, IGF-1 products, including Increlex®, and other products.

In the
United States and Canada, Somatuline® Depot competes directly with Sandostatin LAR® Depot and Somavert® for the treatment of acromegaly. Sandostatin LAR® Depot is a somatostatin analogue and has the same mechanism of action as
Somatuline® Depot. Sandostatin LAR® Depot is indicated for long-term maintenance therapy in patients with acromegaly and in the
treatment of symptoms related to carcinoid syndrome and vasoactive intestinal peptide tumors. Somavert®, a growth hormone antagonist, and Sandostatin LAR® Depot are marketed by Pfizer and Novartis, respectively, in the United States and Canada. Moreover, a subset of patients with acromegaly can be treated with radiotherapy and dopaminergic agonists. These therapies are
commercially available in the United States and Canada and also compete with Somatuline® Depot for the treatment of patients with acromegaly.

We are aware that Ambrilia Biopharma Inc., QLT Inc., Indevus Pharmaceuticals Inc. and Camurus AB
are conducting research and development programs with long-acting versions of octreotide for the treatment of acromegaly. Octreotide is the generic name of the active molecule in Sandostatin and Sandostatin LAR® Depot. We are also aware that Novartis is developing pasireotide (SOM 230), DeveloGen AG is developing Somatoprin (DG 3173), and that Ipsen is developing dopastatin for the treatment of acromegaly and other hormone
secreting tumors. If approved, these therapies would compete with Somatuline® Depot in these indications. It is possible that there are other products currently in development or that exist
on the market that may compete directly with Increlex® or Somatuline® Depot.

We rely solely on single-source third parties in the manufacture, testing, storage and
distribution of Increlex®.

We source all of our Increlex® fill-finish manufacturing and testing and final product storage and distribution operations, as well as all of our bulk
manufacturing, testing, and shipping operations, through single-source third-party suppliers and contractors. Single-source suppliers are the only approved suppliers currently available to us, and could only be replaced by qualification of new sites
for the same operations.

##### Table of Contents

If our contract facilities, contractors or
suppliers become unavailable to us for any reason, including as a result of the failure to comply with cGMP regulations, manufacturing problems or other operational failures, such as equipment failures or unplanned facility shutdowns required to
comply with cGMP, damage from any event, including fire, flood, earthquake or terrorism, business restructuring or insolvency, or if they fail to perform under our agreements with them, such as failing to deliver commercial quantities of bulk drug
substance or finished product on a timely basis and at commercially reasonable prices, we may be delayed in manufacturing Increlex® or may be unable to maintain validation of Increlex® . This could delay or prevent the supply of commercial and clinical product, or delay or otherwise adversely affect revenues. If the damage to any of these facilities is extensive, or, for any
reason, they do not operate in compliance with cGMP or are unable or refuse to perform under our licenses and/or agreements, we will need to find alternative facilities. Further, we are responsible for the manufacture and supply of Increlex® to Ipsen (through our contract manufacturer) for Ipsens clinical development and commercial needs. In the event we fail to meet Ipsens supply obligations, Ipsen would have the right
to exercise its option to manufacture Increlex® on its own or to engage a third-party manufacturer to do so. The number of contract manufacturers with the expertise and facilities to
manufacture rhIGF-1 bulk drug substance on a commercial scale in accordance with cGMP regulations is extremely limited, and it would take a significant amount of time and expense to arrange for alternative manufacturers. If we need to change to
other commercial manufacturers, these manufacturers facilities and processes, prior to our use, would likely have to undergo pre-approval and/or cGMP compliance inspections. In addition, we would need to transfer and validate the processes and
analytical methods necessary for the production and testing of rhIGF-1 to these new manufacturers.

Our inability to timely transfer to an alternate single-source manufacturer to fill-finish Increlex® could adversely affect our commercial supply and
ability to grow revenues.

We currently source all of our Increlex® fill-finish manufacturing and portions of release testing through a single-source third-party supplier. This supplier is the only FDA-approved manufacturer currently available to us, and could
only be replaced by qualification of a new site for the same operations. We have negotiated a short-term commercial agreement with this fill-finish manufacturer and during the term of this agreement, we are attempting to move our process to Hospira
Worldwide, Inc., or Hospira. It will take a significant amount of time and expense to complete the transfer to Hospira and validate Hospira as an alternative manufacturer. For us to complete the transfer to Hospira, Hospiras facilities and
processes, prior to our use, may need to undergo pre-approval and/or cGMP compliance inspections. In addition, we need to transfer and validate the processes and certain analytical methods necessary for the production and testing of Increlex® by Hospira. If we are not able to complete the transfer of fill-finish manufacturing to Hospira, our ability to obtain commercial supplies of Increlex® and our revenue growth could be adversely affected. A delay in this transfer may also result in a shortage of Increlex® and a loss of revenues.

Our inability to timely transfer or to complete the transfer at all to an alternate
single-source manufacturer for bulk Increlex® could significantly adversely affect our commercial supply and ability to grow revenues.

We currently source all of our Increlex® bulk manufacturing and portions of release testing through a single-source third-party supplier, Lonza Baltimore, Inc. This supplier is the only FDA-approved manufacturer currently available to us, and could only be
replaced by qualification of a new manufacturing site for the same operations. We have negotiated a short-term commercial agreement with Lonza Baltimore, and during the term of this agreement, we are attempting to move our bulk manufacturing process
from Lonza Baltimore to Lonza Hopkinton, Inc. It will take a significant amount of time and expense to complete the transfer to and validate the Lonza Hopkinton manufacturing facility. For us to change to this new bulk manufacturing site, Lonza
Hopkintons facilities and processes, prior to our use, will need to undergo pre-approval and/or cGMP compliance inspections. In addition, we need to transfer and validate the processes and certain analytical methods necessary for the
production and testing of bulk Increlex® by Lonza Hopkinton. A delay in this transfer could result in a shortage of bulk Increlex® and a significant loss of revenues. If we are not able to complete this transfer, our ability to supply Increlex® will be impaired and our business will
suffer irreparable harm.

If our contract manufacturers and/or
Ipsens facilities and operations do not maintain satisfactory cGMP compliance, we may be unable to market and sell Increlex® and/or Somatuline® Depot.

The facilities and operations of our
contract manufacturers to manufacture and test Increlex®, and of Ipsen to manufacture and test Somatuline® Depot, must undergo
continuing inspections by the FDA for compliance with cGMP regulations in order to maintain their respective approvals. Currently, Lonza Baltimore is our sole provider of bulk rhIGF-1, and Ipsen is our sole provider of Somatuline® Depot. Other than with respect to our agreement with Lonza Hopkinton, we have no alternative manufacturing facilities or plans for additional facilities at this time. We do not know if the
Lonza Baltimore or Ipsens facilities or their operations required for the commercial manufacture of Increlex® and Somatuline® Depot will continue to receive satisfactory cGMP inspections, and we do not know whether Lonza Hopkinton will receive a satisfactory cGMP inspection. In the event these facilities or operations do not receive, or
continue to receive, satisfactory cGMP inspections for the manufacture of our products, or for the operation of their facilities in general, we may need to

invest in significant compliance improvement programs, fund additional modifications to our manufacturing processes, conduct additional validation studies,
or find alternative manufacturing facilities, any of which would result in significant cost to us as well as result in a delay or prevention of commercialization, and may result in our failure to obtain or maintain approvals. In addition, Lonza
Baltimore, Lonza Hopkinton, Ipsen and any alternative contract manufacturer we may utilize, will be subject to ongoing periodic inspection by the FDA and corresponding state and foreign agencies for compliance with cGMP regulations and similar
foreign standards. We do not have direct control over Ipsens or our contract manufacturers compliance with these regulations and standards. Any of these factors could delay or suspend clinical trials, regulatory submissions or regulatory
approvals, entail higher costs and result in us being unable to effectively market and sell our products or maintain our products in the marketplace, which would adversely affect our ability to generate revenues.

We rely in certain cases on single-source and sole-source materials suppliers to manufacture
Increlex®.

Certain specific components and raw materials used to manufacture Increlex® at our third-party manufacturers are obtained and made available through either single-source or
sole-source suppliers. Single-source suppliers are the only approved suppliers currently available to us, and could only be supplemented by qualification of new sources for the material required. Sole-source suppliers are the only source of supply
available to us, and could only be replaced through qualification of an alternate material after demonstrating suitability. Supply interruption of these materials could result in a significant delay to our manufacturing schedules and ability to
supply product, and any replacement supplier would likely be required to undergo lengthy regulatory approval procedures prior to product distribution. Limits or termination of supply of these materials could significantly impact our ability to
manufacture Increlex®, cause significant supply delays while we qualified, at significant expense, new suppliers or new materials, and would consequently cause harm to our business,
including as a result, our failure to meet our supply obligations to Ipsen.

Difficulties or delays in product manufacturing due to
advance scheduling requirements, capacity constraints and/or manufacturing lot failures at our third-party manufacturers or Ipsen could harm our operating results and financial performance and jeopardize our orphan drug marketing exclusivity.

The manufacture of Increlex® requires successful coordination among all of our suppliers, contractors, service-providers, manufacturers and us. Coordination failures with these different elements of our supply chain, or with Ipsens supply
of Somatuline® Depot to us, could require us to delay sales of our products and/or impair our ability to distribute and supply Increlex® to Ipsen. Furthermore, uncertainties in estimating future demand for new products such as Increlex® and Somatuline® Depot
may result in manufacture of surplus inventory requiring us to record charges for any expired, unused product, or may result in inadequate manufacturing of product inventory, causing delays to shipments or no shipments at all. Additionally, our
reliance on third-party manufacturing requires long lead times from order to delivery of product, and may be hampered by available capacity at those manufacturers, making our ability to supply product supplies in excess of our forecast extremely
difficult. As a consequence, we may have inadequate capacity to meet unexpected demand, which could negatively affect our operating results and our ability to meet our supply obligations to Ipsen. If we are unable to supply our products to all the
patients that need them, the FDA could rescind our orphan drug marketing exclusivity to enable competitors to serve the affected markets. Further, our operating results and financial performance may suffer if we experience more than anticipated
manufacturing lot failures or delivery delays.

If product is lost or damaged during manufacturing, storage or shipment, our business
may suffer.*

We rely entirely on third-party contractors for the manufacturing, shipping and storage of our products. If product in
filled, finished, or other form, or its active ingredient, is lost or damaged while in the possession of our third-party contractors, we may not have adequate rights to seek indemnification from our third-party contractors or their insurance
companies for the replacement cost of the lost or damaged goods. Our agreement with the third-party contractor responsible for the loss or damage may waive their liability altogether or limit their liability to an amount well below the replacement
cost of the lost or damaged goods. In addition, our insurance policies may not provide coverage or may provide inadequate coverage for the lost or damaged goods, or we may decide not to file an insurance claim in order to avoid increasing in the
cost of or cancellation of our insurance and/or to avoid the negative impact such claim could have on our prospective ability to insure our business operations at a commercially reasonable cost or at all. If we cannot recover the replacement cost of
the lost or damaged goods from the responsible third-party contractor or their insurance companies, or our insurance companies, our financial performance may be negatively affected and our business may suffer. In addition, such losses or damages
could delay or prevent us from manufacturing and supplying commercial or clinical product in the time frames or in the quantities that we anticipate will be required for the support of our collaborators product sales or product development
activities, all of which would harm the development and commercial potential of our product.

Claims and concerns may arise regarding the safety and efficacy of our products, which could
require us to perform additional clinical trials, could slow penetration into the marketplace, or cause reduced sales or product withdrawal after introduction.

Increlex® was approved in the United
States for the treatment of severe Primary IGFD based on long-term and extensive studies and clinical trials conducted to demonstrate product safety and efficacy. Somatuline® Depot was
approved in Canada and the United States for the treatment of acromegaly on a similar basis. Discovery of previously unknown problems with the raw materials, product or manufacturing processes, such as loss of sterility, contamination, new data
suggesting an unacceptable safety risk or previously unidentified side effects or an unfavorable risk-benefit ratio for these products, could result in a voluntary or mandated withdrawal of the products from the marketplace, either temporarily or
permanently. Studies may result in data or evidence suggesting another product is safer, better tolerated, or more efficacious than our products, which could lead to reduced sales and royalties. Additionally, discovery of unknown problems with our
products or manufacturing processes for our products could negatively impact the established safety and efficacy profile and result in possible reduced sales or product withdrawal. Such outcomes could negatively and materially affect our product
sales, royalty stream, operating results, and financial condition.

If other
companies overcome our U.S. orphan drug marketing exclusivity for Increlex® or Somatuline® Depot, or obtain marketing
authorization in Europe for the treatment of severe Primary IGFD, they will be able to compete with us, and our revenues will be diminished.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to drugs intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States. The
company that obtains the first FDA approval for a designated orphan drug for a rare disease receives marketing exclusivity for use of that drug for the designated condition for a period of seven years from the date of approval. The orphan drug rules
are similar in the European Union and marketing exclusivity is for a period of ten years from the date of approval.

The FDA has granted Increlex® orphan drug marketing exclusivity for the long-term treatment of patients with severe Primary IGFD and has granted
Somatuline® Depot orphan drug marketing exclusivity for the long-term treatment of acromegaly. In the European Union, the European Medicines Agency (EMEA) has granted Increlex orphan drug
marketing exclusivity for the long-term treatment of patients with severe Primary IGFD. Although Increlex® and Somatuline®
Depot have received marketing exclusivity, the FDA and EMEA can still approve different drugs for use in treating the same indication or disease covered by our products, which would create a more competitive market for us.

Furthermore, drugs considered to be the same as Increlex® or Somatuline® Depot that demonstrate clinical superiority or provide a major contribution to patient care may be approved for marketing by the FDA and EMEA
notwithstanding the grant of orphan drug marketing exclusivity. If other companies are able to overcome our U.S. orphan drug exclusivity, they will be able to compete with us, and our revenues will be diminished.

We will not be able to sell our products if we are not able to maintain our regulatory approvals due to changes to existing regulatory
requirements.

Our products and manufacturing processes are subject to continued review and ongoing regulation by the FDA and
foreign regulatory authorities post approval, including, for example, changes to manufacturing process standards or good manufacturing practices, changes to product labeling, revisions to existing requirements or new requirements for manufacturing
practices, or changing interpretations regarding regulatory guidance. Such changes in the regulatory environment and requirements could occur at any time during commercialization. Changes in the regulatory environment or requirements could adversely
affect our ability to maintain our approval or require us to expend significant resources to maintain our approvals, which could result in the possible withdrawal of our products from the marketplace, which would harm our business and negatively
impact our financial performance.

Competitors could develop and gain FDA approval of products containing rhIGF-1 or lanreotide,
which could adversely affect our competitive position.

In the future,
rhIGF-1 or lanreotide manufactured by other parties may be approved for use in the United States. For example, we are aware that Novartis AG (through the acquisition of Chiron Corporation) has developed a process to manufacture rhIGF-1 using yeast
expression and has intellectual property with respect to that process. In the event there are other rhIGF-1 products approved by the FDA to treat indications other than those covered by Increlex®, physicians may elect to prescribe a competitors product containing rhIGF-1 to treat the indications for which Increlex® has received and may receive approval. This is
commonly referred to as off-label use. While under FDA regulations a competitor is not allowed to promote off-label use of its product, the FDA does not regulate the practice of medicine and as a result cannot direct physicians as to which product
containing rhIGF-1 to prescribe to their patients. In addition, a competitor could gain FDA approval of a product containing lanreotide for the treatment of an indication other than indication(s) covered by Somatuline® Depot, which would enable physicians to prescribe the competitors product for the indication(s) covered by Somatuline® Depot. As a result, we would
have limited ability to prevent off-label use of a competitors product containing rhIGF-1 or lanreotide to treat any diseases for which we have received FDA approval, even if it violates our method of use patents and/or we have orphan drug
exclusivity for the use of rhIGF-1 or lanreotide to treat such diseases.

Competitors could challenge our patents and
file an Abbreviated New Drug Application, or ANDA, or a 505(b)(2) new drug application for an IGF-1 or Somatuline® Depot product and adversely affect the competitive position of each.

Products approved for commercial marketing by the FDA are subject to the
provisions of the Drug Price Competition and Patent Term Restoration Act of 1984, or Hatch-Waxman Act. The Hatch-Waxman Act provides companies with marketing exclusivity for varying time periods during which generic or modified versions
of a drug may not be marketed and allows companies to apply to extend patent protection for up to five additional years. It also provides a means for approving generic versions of a drug once the marketing exclusivity period has ended and all
relevant patents have expired. The period of exclusive marketing, however, may be shortened if a patent is successfully challenged and defeated. Competitors with a generic IGF-1 or Somatuline® Depot product or a modified version of IGF-1 or Somatuline® Depot may attempt to file an ANDA or a 505(b)(2) NDA and challenge our patents and marketing exclusivity. Such
applications would have to certify that one of the patents in the Increlex® or Somatuline® Depot NDA is invalid or not infringed
by the manufacture, use, or sale of the product described in that ANDA or 505(b)(2) application under the Hatch-Waxman Act. If successful, a competitor could come to market at an earlier time than expected. We can provide no assurances that we can
prevail in a challenge or litigation related to our patents or exclusivity.

We are subject to fraud and abuse and
similar laws and regulations, and a failure to comply with such regulations or prevail in any litigation related to noncompliance could harm our business.

We are subject to various health care fraud and abuse laws, such as the Federal False Claims Act, the federal anti-kickback statute and other state and federal laws and regulations. Pharmaceutical
companies have faced lawsuits and investigations pertaining to violations of these laws and regulations. We cannot guarantee that measures that we have taken to prevent such violations, including our corporate compliance program, will protect us
from future violations, lawsuits or investigations. If any such actions are instituted against us, and we are not successful in defending ourselves or asserting our rights, those actions could have a significant impact on our business, including the
imposition of significant fines or other sanctions.

If we fail or are unable to protect or defend our intellectual property rights,
competitors may develop competing products, and our business will suffer.

If
we are not able to protect our proprietary technology, trade secrets and know-how, our competitors may use our inventions to develop competing products. We have licensed intellectual property rights, including patent rights, relating to rhIGF-1, our
growth hormone/IGF-1 combination product candidates, and Somatuline® Depot technologies from Genentech and Ipsen, respectively. However, these patents may not protect us against our
competitors. Patent litigation is very expensive, and we therefore may be unable to pursue patent litigation to its conclusion because currently we do not generate meaningful revenues.

We do not have composition of matter patent coverage on the rhIGF-1 protein alone. Although we have licensed from Genentech its rights to its methods of
use and manufacturing patents, it may be more difficult to establish infringement of such patents as compared to a patent directed to the rhIGF-1 protein alone. Our licensed patents may not be sufficient to prevent others from competing with us. We
cannot rely solely on our patents to be successful. The standards that the U.S. Patent and Trademark Office and foreign patent offices use to grant patents, and the standards that U.S. and foreign courts use to interpret patents, are not the same
and are not always applied predictably or uniformly and can change, particularly as new technologies develop. As such, the degree of patent protection obtained in the United States may differ substantially from that obtained in various foreign
countries. In some instances, patents have issued in the United States while substantially less or no protection has been obtained in Europe or other countries. Our U.S. Patent No. 6,331,414 B1 licensed from Genentech is directed to methods for
bacterial expression of rhIGF-1 and expires in 2018. We have no equivalent European patent. The European Patent Office has determined that the claims of Genentechs corresponding European patent application are not patentable under European
patent law in view of public disclosures made before the application was filed.

We
do not have composition of matter patent coverage on the lanreotide molecule (the active pharmaceutical ingredient of Somatuline® Depot) alone. We have licensed from Ipsen its rights to
formulation and method of use patents for Somatuline® Depot that expire between 2015 and 2019. However, there can be no assurance that we have patent rights sufficient to prevent others
from competing with us.

We do not have composition of matter patent coverage on either the growth hormone or the IGF-1 component of our
growth hormone/IGF-1 combination product candidates. Our U.S. Patent No. 5,374,620 and our equivalent European Patent No. 0 536 226 B1, both of which are licensed from Genentech, are composition of matter patents covering combinations of

growth hormone and IGF-1 and expire in 2009 and 2011, respectively. Therefore, it is likely that these patents will expire before we are able to launch any
growth hormone/IGF-1 combination product in the U.S. or in European markets. We have also licensed from Genentech certain method of use patents for our growth hormone/IGF-1 combination product candidates that expire between 2009 and 2014. Our U.S.
Patent No. 6,331,414 B1 licensed from Genentech will provide protection in the United States for our process of manufacturing IGF-1 for our growth hormone/IGF-1 combination product candidates until it expires in 2018. We have no equivalent
patent protection for our process of manufacturing IGF-1 in Europe.

If we attempt
to enforce against a competitor the patent rights we have licensed from Ipsen or the patent rights we have licensed from Genentech, and if such patents are challenged in court by defenses the competitor may raise, such as invalidity,
unenforceability or possession of a valid license, we may fail to stop the competitor and we may lose the ability to assert the affected patents against other competitors as well. If we assert the patents we licensed from Ipsen or the patents we
licensed from Genentech in an infringement proceeding against a competitor, and if the court were to find in favor of any defense of invalidity or unenforceability raised by the competitor against the asserted patents, we would be unable to use the
affected patents to exclude others from competing with Somatuline® Depot or Increlex®. In addition, the type and extent of patent
claims that will be issued to us in the future are uncertain. Any patents that are issued may not contain claims that will permit us to stop competitors from using technology similar to our Increlex®, or any growth hormone/IGF-1 combination product or Somatuline® Depot technologies.

In addition to the patented technology licensed from Genentech and Ipsen, we also rely on
unpatented technology, trade secrets and confidential information, such as the proprietary information we use to manufacture Increlex®. We may not be able to effectively protect our rights
to this technology or information. Other parties may independently develop substantially equivalent information and techniques or otherwise gain access to or disclose this technology. We generally require each of our employees, consultants,
collaborators, and certain contractors to execute a confidentiality agreement at the commencement of an employment, consulting or collaborative relationship with us. However, these agreements may not provide effective protection of this technology
or information or, in the event of unauthorized use or disclosure, they may not provide adequate remedies.

We may incur substantial
costs as a result of patent infringement litigation or other proceedings relating to patent and other intellectual property rights, and we may be unable to protect our intellectual property rights.

A third-party may claim that we are using its inventions covered by its patents and may initiate litigation to stop us from engaging in our operations and
activities. Although no third party has claimed that we are infringing on their patents, patent lawsuits are costly and could affect our results of operations and divert the attention of managerial and technical personnel. There is a risk that a
court would decide that we are infringing the third partys patents and would order us to stop the activities covered by the patents. In addition, there is a risk that a court will order us to pay the other party damages for having infringed
the other partys patents. The biotechnology industry has produced a proliferation of patents, and it is not always clear to industry participants, including us, which patents cover various types of products or methods of use. The coverage of
patents is subject to interpretation by the courts, and the interpretation is not always uniform. If we are sued for patent infringement, we would need to demonstrate that our products or methods of use do not infringe the patent claims of the
relevant patent and/or that the patent claims are invalid, and we may not be able to do so. Proving invalidity, in particular, is difficult since it requires a showing of clear and convincing evidence to overcome the presumption of validity enjoyed
by issued patents.

We are aware of a U.S. patent of Novartis related to processes
of manufacturing rhIGF-1 in yeast host cells, to fusion proteins, DNA, and yeast host cells useful in such processes of manufacturing rhIGF-1 in yeast host cells, and to rhIGF-1 made as a product of such processes. While we use bacterial expression,
not yeast expression, in our process for manufacturing Increlex®, we cannot predict whether our activities relating to the development and commercialization of Increlex® in the United States will be found to infringe Novartiss patent in the event Novartis brings patent infringement proceedings against us. We may not be able to obtain a license to
Novartiss patent under commercially reasonable terms, if at all. If we are unable to obtain a license to Novartiss patent, and if in any patent infringement proceeding Novartis brings against us the court decides that our activities
relating to the development and commercialization of Increlex® in the United States infringe Novartiss patent, the court may award damages and/or injunctive relief to Novartis. Any
such damages, injunctive relief and/or other remedies the court may award could render any further development and commercialization of Increlex® commercially infeasible for us or otherwise
curtail or cease any further development and commercialization of Increlex®.

We cannot be certain that others have not filed patent applications for technology covered by the issued patents of any of our licensors, or by our pending applications or by the pending applications of any of our licensors, or that we or
any of our licensors were the first to invent the technology because:

| |  |  | publications in the scientific literature often lag behind actual discoveries and the filing of patents relating to those discoveries.
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------

Patent applications may have been filed and may be filed in the future covering technology similar to ours. Any such patent application may have
priority over our patent applications and could further require us to obtain rights to issued patents covering such technologies. In the event that another party has filed a U.S. patent application on inventions similar to ours, we may have to
participate in an interference proceeding declared by the U.S. Patent and Trademark Office to determine priority of invention in the United States. The costs of these proceedings could be substantial, and it is possible that such efforts would be
unsuccessful, resulting in a loss of our U.S. patent position with respect to such inventions.

Some of our competitors may be able to
sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources. In addition, any uncertainties resulting from the initiation and continuation of any litigation could harm our business.

Ipsen may seek to influence our business in a manner that is contrary to our goals or strategies or to the interests of our other
stockholders.*

Based on its significant ownership position through certain protective provisions, Ipsen has the ability to
significantly influence the outcome of certain actions by our Board of Directors and those requiring the approval of our stockholders. Our other stockholders may be unable to prevent actions taken by Ipsen. Together with the 13,046,346 shares of our
common stock that we have issued to Ipsen (and/or an affiliate of Ipsen), the conversion of the convertible notes and the exercise of the warrant that we have also issued to Ipsen would enable Ipsen to acquire an ownership interest in us of
approximately 40% on a fully diluted basis, with the opportunity to increase its ownership position to 60% or greater through market purchases. Ipsen was also granted a preemptive right to purchase its pro rata portion of new securities that
we may offer in the future to maintain its percentage ownership interest. In addition, under the terms of our affiliation agreement with Ipsen, so long as Ipsen holds at least 15% of the outstanding shares of our common stock, Ipsen is entitled to
nominate two out of the nine directors on our Board of Directors. In the event that Ipsen holds at least 10% of the outstanding shares of our common stock, but less than 15%, it would be entitled to nominate one director to our Board of Directors.
Our affiliation agreement with Ipsen also provides that in the event Ipsen holds at least 60% of the outstanding shares of our common stock, Ipsen is entitled to nominate an unlimited number of directors to our Board of Directors (and under our
charter documents, holders of at least 60% of the outstanding shares of our common stock may remove any director or the entire Board of Directors without cause). For so long as Ipsen holds at least 15% of the outstanding shares of our common stock,
Ipsen is also entitled to nominate additional independent director nominees, who must be independent of Ipsen, starting with one in 2008 and up to four after our 2009 annual meeting of stockholders. Our certificate of incorporation was also amended
in connection with our collaboration with Ipsen to waive the corporate opportunity provisions under Delaware law and the corporate opportunity doctrine with respect to opportunities of which Ipsen and Ipsens designees to our Board of Directors
may become aware as a result of their affiliation with us. Additionally, our certificate of incorporation provides that any person purchasing or acquiring an interest in shares of our common stock shall be deemed to have consented to these
provisions of our certificate of incorporation. This deemed consent might restrict the ability to challenge transactions carried out in compliance with these provisions. We make no assurances that Ipsen will not seek to influence our business in a
manner that is contrary to our goals or strategies or the interests of other stockholders. Moreover, persons who are directors and/or officers of Ipsen and who also serve on our Board of Directors may decline to take action in a manner that might be
favorable to us but adverse to Ipsen. Currently, one of our directors, Christophe Jean, also serves as the Chief Operating Officer of Ipsen.

If we lose our licenses from Genentech or Ipsen, we may be unable to continue our business.*

We have licensed intellectual property rights and technology from Genentech and from Ipsen. Under our license and collaboration agreements with Genentech and Ipsen, each of Genentech and Ipsen have the right to
terminate our licenses if we are in material breach of our obligations under our agreements with them and fail to cure that breach. Under the terms of the agreements, we are obligated, among other things, to use reasonable business efforts to meet
specified milestones. If any of these agreements are terminated, then we would lose our rights to utilize the technology and intellectual property covered by that agreements license to develop, manufacture, market and sell Increlex®, to develop, market and sell Somatuline® Depot, or to develop, manufacture, market and sell our growth hormone/IGF-1 combination
product candidates. This may prevent us from continuing our business.

We are subject to Genentechs option
rights with respect to the commercialization of Increlex® for all diabetes and non-orphan indications in the United States; Ipsens right of first negotiation to develop and
commercialize other endocrine products subsequently acquired or owned by us; and Genentechs option rights with respect to our growth hormone/IGF-1 combination product candidates.

Under our U.S. license and collaboration agreement with Genentech for Increlex®, Genentech has the option to elect to jointly commercialize rhIGF-1 for all diabetes and non-orphan indications in the United States. Orphan indications are designated by the FDA under the
Orphan Drug Act, and are generally rare diseases or conditions that affect fewer than 200,000 individuals in the United States. With respect to those non-orphan and diabetes indications in the United States, once Genentech has exercised its option
to jointly develop and commercialize, Genentech has the final decision on disputes relating to the development and commercialization of such indications. Our ability to sublicense the development and commercialization of such products requires the
consent of Genentech. Under a letter agreement of July 2007, we and Genentech amended the U.S. license and collaboration agreement to provide that until such time as we initiate the development of rhIGF-1 for diabetes (or a substitute indication
mutually agreed to by us and Genentech that has a potential market of greater than $250 million and is not an indication for the central nervous system), Genentech may elect to initiate such development for diabetes or, upon our and Genentechs
mutual agreement, the development of a substitute indication that has a potential market size of greater than $250 million and is not an indication of the central nervous system. In addition, if we elect to discontinue the development of rhIGF-1 for
diabetes or a substitute indication selected by us with Genentechs consent, Genentech has the right to assume development of such indication. In the event that Genentech initiates the development of rhIGF-1 for any such indication before we do
or assumes the development of rhIGF-1 for any such indication after such development is discontinued by us, our rights under the agreement for such indication would terminate and Genentech would be granted a non-exclusive license under our rhIGF-1
intellectual property and technology to manufacture, use and sell rhIGF-1 products for diabetes, or if applicable the substitute indication, subject to an obligation to pay us milestone payments and/or royalties to be negotiated by Genentech and us
in good faith on sales of these products.

Under our license and collaboration
agreement with Ipsen with respect to Increlex®, Ipsen has a right of first negotiation to develop and commercialize, in Ipsens territory, other products subsequently acquired or owned
by us in the field of endocrinology. Accordingly, we may not receive a reasonable return on our investment if we develop new endocrinology products. In its territory, Ipsen also has the exclusive right to sublicense our growth hormone/IGF-1
combination product candidates. Accordingly, we have limited ability to sublicense these candidates to other parties.

Under our
development and commercialization agreement with Genentech with respect to our growth hormone/IGF-1 combination product candidates, Genentech has a right to opt into our development and commercialization for short stature indications, AGHD and
certain other indications. If Genentech opts in, it would still have the right to subsequently elect to opt out of such development and commercialization of such combination product candidates and products, but only for all indications. Following an
opt-in by Genentech, Genentech would control the joint development and commercialization of the combination product candidates and products for certain other indications and could assume control of the joint development and/or commercialization of
products for the treatment of AGHD. Upon opt-in, Genentech may also choose to exercise a commercial option to acquire the right for the deciding vote on all commercialization matters pertaining to short stature indications; however, we would remain
the lead commercialization party for short stature indications. Because of Genentechs ability to control the timing and extent of such joint development and commercialization activities and our obligation to co-fund such activities, Genentech
may induce us to bear an excessive financial burden in support of or to opt out of the joint development and commercialization of our combination product candidates and/or products for AGHD and certain other indications. In addition, our ability to
sublicense the development and commercialization of our growth hormone/IGF-1 combination product candidates requires the consent of Genentech.

Accordingly, because of these various option, limits on sublicensing, and right of first
negotiation rights, we may not receive a reasonable return on our investment for developing and/or commercializing Increlex® or our growth hormone/IGF-1 combination product candidates.

If third-party clinical research organizations do not perform in an acceptable and timely manner, our clinical trials could be
delayed or unsuccessful.

We do not have the ability to conduct all of our clinical trials independently. We rely on clinical
investigators, third-party clinical research organizations and consultants to perform a substantial portion of these functions. If we cannot locate acceptable contractors to run our clinical trials or enter into favorable agreements with them, or if
these contractors do not successfully carry out their contractual duties, satisfy FDA requirements for the conduct of clinical trials, or meet expected deadlines, we may be unable to obtain or maintain required approvals and may be unable to market
and sell our products on a timely basis, if at all.

If we fail to identify and in-license other patent rights, products or product candidates, we may
be unable to grow our revenues.

We do not conduct any discovery research. Our strategy is to in-license products or product
candidates and further develop them for commercialization. The market for acquiring and in-licensing patent rights, products and product candidates is intensely competitive. If we are not successful in identifying and in-licensing other patent
rights, products or product candidates, we may be unable to grow our revenues with sales from additional products. Further, under the terms of our collaboration with Ipsen, Ipsen has certain approval rights with respect to our entering into material
contracts or transactions, making capital expenditures or acquiring certain assets. Accordingly, Ipsen may prevent us from in-licensing products or product candidates. In addition, under the terms of our collaboration, Ipsen has a right of first
negotiation to develop and commercialize, in Ipsens territory, products subsequently acquired or owned by us in the field of endocrinology. Under our combination product agreement with Genentech, Genentech has certain opt-in rights with
respect to our development and commercialization of combination products and, with respect to certain combination products, to become the lead party for the planning, development and/or commercialization of such combination products.

In addition, we may need additional intellectual property from other third parties to market and sell our products. We cannot be certain that we will be
able to obtain a license to any third-party technology we may require to conduct our business.

The committed equity financing
facility that we entered into with Kingsbridge Capital Limited may not be available to us if we elect to make a draw down, and may require us to pay certain liquidated damages.

In October 2005, we entered into a committed equity financing facility, or CEFF, with Kingsbridge Capital Limited, or Kingsbridge, which entitles us to
sell and obligates Kingsbridge to purchase, from time to time over a period of three years, newly issued shares of our common stock for cash consideration of up to an aggregate of $75.0 million, subject to certain conditions and restrictions.
Kingsbridge will not be obligated to purchase shares under the CEFF unless certain conditions are met, which include:



| |  |  | a minimum price for our common stock;
| | - |  | -------------------------------------



| |  |  | the accuracy of representations and warranties made to Kingsbridge;
| | - |  | -------------------------------------------------------------------



| |  |  | compliance with laws;
| | - |  | ---------------------



| |  |  | continued effectiveness of the registration statement, filed by us with the U.S. Securities and Exchange Commission, or SEC, for the resale of the shares of common
stock issuable in connection with the CEFF and the shares of common stock underlying the warrant we issued to Kingsbridge in connection with the entering into of the CEFF; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the continued listing of our stock on the NASDAQ Global Market.
| | - |  | ---------------------------------------------------------------

In addition, Kingsbridge is permitted to terminate the CEFF if it determines that a material and adverse event has occurred affecting our business, operations, properties or financial condition. If we are unable to
access funds through the CEFF, or if the CEFF is terminated by Kingsbridge, we may be unable to access capital on favorable terms or at all.

The terms of the CEFF require us to pay certain liquidated damages in the event that the registration statement filed by us with the SEC is not available for the resale of securities purchased by Kingsbridge under the CEFF or upon exercise
of the warrant we issued to Kingsbridge. Except for certain periods of ineffectiveness permitted under the CEFF, we are obligated to pay to Kingsbridge an amount equal to the number of shares purchased under the CEFF and held by Kingsbridge at the
date the registration statement becomes unavailable, multiplied by any positive difference in price between the volume weighted average price on the trading day prior to such period of unavailability and the volume weighted average price on the
first trading day after the period of unavailability. In addition, we are entitled in certain circumstances to deliver a blackout notice to Kingsbridge to suspend the use of the registration statement and prohibit Kingsbridge from
selling shares under the registration statement. If we deliver a blackout notice in the 15 trading days following a settlement of a draw down, then we must make a blackout payment to Kingsbridge as liquidated damages, or issue Kingsbridge additional
shares in lieu of this payment, calculated by means of a varying percentage of an amount based on the number of shares purchased and held by Kingsbridge and the change in the market price of our common stock during the period in which the use of the
registration statement is suspended. If the trading price of our common stock declines during a suspension of the registration statement, the blackout payment could be significant and could adversely affect our liquidity and our ability to raise
capital. In addition, under the terms of an affiliation agreement we entered into pursuant to our collaboration with Ipsen, we have only a limited ability to raise capital through the sale of our equity securities, including pursuant to the CEFF,
without first obtaining Ipsens approval.

We may not have the ability to raise the funds necessary to finance the repayment of the
convertible notes we issued to Ipsen, which could adversely affect our cash position and harm our business.

Under the terms of our
collaboration with Ipsen, we issued to Ipsen convertible notes in the principal amounts of $25.0 million, 30.0 million and $15.0 million. All of these notes mature on the later of October 13, 2011 or two years from the date of
notification of non-convert, and carry a 2.5% coupon per annum from the date of issuance, compounded quarterly. If Ipsen (or a subsequent holder) chooses not to convert these notes, we would be required to pay to Ipsen the principal amount of the
notes plus accrued interest at maturity. We are also subject to currency risk on the 30.0 million principal amount convertible note that we issued to Ipsen which, if the note is not converted, may result in the need to raise a greater
amount of U.S. dollars to repay this note at maturity than would be required based on a conversion of this note to U.S. dollars at the time we entered into the stock purchase and master transaction agreement with Ipsen in July 2006 or issuance of
the note. If we are required to repay the notes in cash, we will likely need to raise such amounts from the capital markets or through a strategic transaction. There is no assurance that we would be able to do so in a timely manner or on reasonable
terms. If we are unable to do so, we may be required to delay or curtail our development and commercialization efforts, which would harm our business.

Our indebtedness to Ipsen could have significant additional negative consequences, including, but not limited to:



| |  |  | increasing our vulnerability to general adverse economic and industry conditions;
| | - |  | ---------------------------------------------------------------------------------



| |  |  | limiting our ability to obtain additional financing;
| | - |  | ----------------------------------------------------



| |  |  | limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete; and
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | placing us at a possible competitive disadvantage to less leveraged competitors and competitors that have better access to capital resources.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------

If we fail to obtain the capital necessary to fund our operations, we will be unable to execute our business plan.
*

We believe that our cash, cash equivalents and short-term investments as of March 31, 2008 will be sufficient to meet our
projected operating and capital expenditure requirements through at least March 31, 2009 based on our current business plan. However, our future capital needs and the adequacy of our available funds will depend on many factors, including:



| |  |  | changes to our business plan;
| | - |  | -----------------------------



| |  |  | our ability to market and sell sufficient quantities of Increlex® and Somatuline® Depot at the anticipated level;
| | - |  | -----------------------------------------------------------------------------------------------------------------



| |  |  | the commercial status of the Increlex® bulk drug
manufacturing operations at Lonza Baltimore Inc. and Lonza Hopkinton Inc., including the success of our cGMP production activities;
| | - |  | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the success of Increlex® final drug product manufacturing;
| | - |  | ----------------------------------------------------------



| |  |  | the costs, timing and scope of additional regulatory approvals for Increlex® use in Primary IGFD and/or other regions;
| | - |  | ----------------------------------------------------------------------------------------------------------------------



| |  |  | Ipsens ability to supply Somatuline® Depot to us in
sufficient quantities;
| | - |  | ---------------------------------------------------------------------------



| |  |  | the costs, timing and scope of additional regulatory approvals for Somatuline® Depot;
| | - |  | -------------------------------------------------------------------------------------



| |  |  | Ipsens ability to market and sell sufficient quantities of Increlex® in the licensed territories at the anticipated level;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | any required repayment of the convertible notes we issued to Ipsen;
| | - |  | -------------------------------------------------------------------



| |  |  | the status of competing products;
| | - |  | ---------------------------------



| |  |  | the rate of progress and cost of our future clinical trials and other research and development activities, including research and development activities and
clinical trial costs in connection with our growth hormone/IGF-1 combination product candidates; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the pace of expansion of administrative and legal expenses.
| | - |  | -----------------------------------------------------------

We expect capital outlays and operating expenditures to increase over the next several years as we expand our operations. We expect that we may require and attempt to raise additional funds through equity or debt
financings, collaborative arrangements with corporate partners or from other sources, including potentially the CEFF. However, there can be no assurance that additional financing will be available when needed, or, if available, that the terms will
be favorable. In addition, under the terms of an affiliation agreement we entered into pursuant to our collaboration with Ipsen, we have only a limited ability to raise capital through the sale of our equity without first obtaining Ipsens
approval. Although we have entered into a stock purchase agreement with Genentech pursuant to which we may issue up to an additional 1,894,737 shares of common stock (or up to a maximum of $9.0 million of shares of common stock) to Genentech, such
issuances are subject to various conditions, including a Genentech opt in and the achievement of a regulatory approval milestone, and there can be no assurance that we will receive additional funds from Genentech pursuant to the stock purchase
agreement. Further,

we must first obtain Ipsens approval to issue shares of common stock to Genentech under our stock purchase agreement with Genentech at a price per
share less than $4.75, which we may not be able to obtain. If additional funds are not available, we may be forced to curtail or cease operations.

If we are unable to manage our expected growth, we may not be able to implement our business plan. *

Our ability to
implement our business plan requires an effective planning and management process. As of March 31, 2008, we had 139 full-time employees, and we expect to hire additional employees in the near term. Our offices are located in the San Francisco
Bay area where competition for personnel with biopharmaceutical skills is intense. If we fail to identify, attract, retain and motivate these highly skilled personnel, we may be unable to continue our development and commercialization activities.

We believe that our anticipated future growth may strain our management, systems and resources. To manage the anticipated growth of our
operations, we may need to increase management resources and implement additional financial and management controls, reporting systems and procedures. If we are unable to manage our growth, we may be unable to execute our business strategy.

If product liability lawsuits are brought against us, we may incur substantial liabilities.

One potential risk of using growth factors like rhIGF-1 is that it may increase the likelihood of
developing cancer or, if patients already have cancer, that the cancer may develop more rapidly. Increlex® may also increase the risk that diabetic patients may develop or worsen an
existing retinopathy, which could lead to the need for additional therapy such as laser treatment of the eyes or result in blindness. In our Phase III clinical trials for severe Primary IGFD, the data of which we submitted to the FDA in our NDA,
some patients experienced hypoglycemia, or low blood glucose levels. Other side effects noted in some patients include hearing deficits, enlargement of the tonsils and intracranial hypertension.

Somatuline® Depot is a member of a
class of products known as somatostatin analogs, which have the potential to cause gallstones and other disorders associated with obstruction of the biliary tract, including pancreatitis. These products also alter the balance between the
counter-regulatory hormones insulin, glucagon and growth hormone, which may result in hypoglycemia or hyperglycemia, and suppress secretion of thyroid stimulating hormone, which may result in hypothyrodism. Cardiac conduction abnormalities have also
occurred during treatment with this class of drugs.

There may also be other adverse
events associated with the use of Increlex® or Somatuline® Depot, and adverse events may arise that are related to our growth
hormone/IGF-1 combination product candidates, which may result in product liability suits being brought against us. While we have licensed the rights to develop, market and sell Increlex®,
Somatuline® Depot and our growth hormone/IGF-1 combination product candidates in certain indications, with the exception of certain liabilities covered up to certain limits by our insurance
policies, we are not indemnified by any third party, including our contract manufacturers, for any liabilities that we bear and that arise out of our development or use of any of these products or product candidates.

Whether or not we are ultimately successful in defending product liability litigation, such litigation would consume substantial amounts of our financial
and managerial resources, and might result in adverse publicity or reduced acceptance of our products in the market, or product candidates in development, all of which would impair our business. We have obtained clinical trial insurance and product
liability insurance; however, we may not be able to maintain our clinical trial insurance or product liability insurance at an acceptable cost, if at all, and this insurance may not provide adequate coverage against potential claims or losses.

In addition, we are contractually obligated to indemnify certain contract manufacturers for certain liabilities that they would otherwise
bear and that arise from use of our products or product candidates. Because such contractually assumed liabilities are not covered by any of our insurance policies, the negative financial impact of any such liability could hinder or prevent us from
continuing our business.

Budgetary or cash constraints may force us to delay our efforts to develop certain research and development
programs in favor of developing others, which may prevent us from meeting our stated timetables and completing these projects through to product commercialization.

Because we are a company with limited financial resources, and because research, development and commercialization activities are costly processes, we must regularly prioritize the most efficient allocation of our
financial resources. For example, we may choose to delay or abandon our research and development efforts for the treatment of a particular indication or project to allocate those resources to another indication or project, or to commercialization
activities, which could cause us to fall behind our initial timetables for development. As a result, we may not be able to fully realize the value of some of our product candidates in a timely manner, since they will be delayed in reaching the
market, or may not reach the market at all.

We must implement additional finance and accounting systems, procedures and controls as we grow our
business and organization.

As a public reporting company, we must comply with the Sarbanes-Oxley Act of 2002 and the related rules
and regulations of the SEC, including expanded disclosures and accelerated reporting requirements and more complex accounting rules. Compliance with Section 404 of the Sarbanes-Oxley Act of 2002, or Section 404, and other requirements have
increased our costs and required additional management resources. We have upgraded our finance and accounting systems, procedures and controls and will need to continue to implement additional procedures and controls as we grow our business and
organization. Section 404 requires annual management assessments of the effectiveness of our internal control over financial reporting and an opinion by our independent registered public accountants on the effectiveness of internal controls
over financial reporting. If our independent registered public accounting firm is unable to provide us with an unqualified report as to the effectiveness of our internal control over financial reporting, investors could lose confidence in the
reliability of our internal control over financial reporting, which could adversely affect our stock price.

If we are unable to
attract and retain additional qualified personnel, our ability to market and sell our products and develop other product candidates will be harmed.*

Our success depends on our continued ability to attract and retain highly qualified management and scientific personnel and on our ability to develop relationships with leading academic scientists and clinicians. We
are highly dependent on our current management and key commercial, medical, scientific, regulatory and pharmaceutical operations personnel, whose knowledge of our industry and technical expertise would be extremely difficult to replace. We have
at-will employment contracts with all of our executive officers. They may terminate their employment without cause or good reason and without notice to us.

Risks Related to Our Common Stock

If our results do not meet our and analysts forecasts and expectations, our
stock price could decline.

Analysts who cover our business and operations provide valuations regarding our stock price and make
recommendations whether to buy, hold or sell our stock. Our stock price may be dependent upon such valuations and recommendations. Analysts valuations and recommendations are based primarily on our reported results and our and their forecasts
and expectations concerning our future results regarding, for example, expenses, revenues, clinical trials, regulatory marketing approvals and competition. Our future results are subject to substantial uncertainty, and we may fail to meet or exceed
our and analysts forecasts and expectations as a result of a number of factors, including those discussed under the section entitled Risks Related to Our Business above. If our results do not meet our and analysts forecasts
and expectations, our stock price could decline as a result of analysts lowering their valuations and recommendations or otherwise.

If our officers, directors and largest stockholders choose to act together, they are able to control our management and operations, acting in their best interests and not necessarily those of other stockholders. *

As of March 31, 2008, our directors, executive officers and principal stockholders and their affiliates beneficially owned approximately 81.2% of
our common stock. Our greater than five percent beneficial owners include Ipsen and its affiliates, which beneficially owned 42.7% (not including shares subject to limited voting agreements with certain of our stockholders); entities affiliated with
MPM BioVentures III LLC, which beneficially owned 13.4%; entities affiliated with Prospect Management Co. II, LLC, which beneficially owned 5.9%; MedImmune, Inc., which beneficially owned 5.8%; and entities affiliated with Rho Capital Partners,
which beneficially owned 5.8%. Our directors, executive officers and principal stockholders and their affiliates collectively have the ability to determine the election of all of our directors and to determine the outcome of most corporate actions
requiring stockholder approval. They may exercise this ability in a manner that advances their best interests and not necessarily those of other stockholders.

Our collaboration with Ipsen limits our ability to enter into transactions and to pursue opportunities in conflict with Ipsen, which could cause the price of our common stock to decline.

Under the terms of an affiliation agreement we entered into pursuant to our collaboration with Ipsen, the approval of Ipsen is required for us to take
certain actions, including, but not limited to:



| |  |  | entering into most material transactions or agreements;
| | - |  | -------------------------------------------------------



| |  |  | merging or consolidating with other entities;
| | - |  | ---------------------------------------------

##### Table of Contents

| |  |  | establishing or approving an operating budget with anticipated research and development spending in excess of $25.0
million per year, plus potential additional amounts for new Ipsen projects under the license and collaboration agreement we entered into with respect to Somatuline® Depot;
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | subject to limited exceptions, incurring any indebtedness other than certain permitted indebtedness (provided that our total permitted indebtedness may not exceed
$2.5 million if our ratio of net indebtedness to EBITDA exceeds 1:1);
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | incurring capital expenditures of more than $2.0 million in any given year;
| | - |  | ---------------------------------------------------------------------------



| |  |  | making any investment, other than certain permitted investments;
| | - |  | ----------------------------------------------------------------



| |  |  | entering into any transaction that results in competition with Ipsen;
| | - |  | ---------------------------------------------------------------------



| |  |  | declaring or paying any cash dividends;
| | - |  | ---------------------------------------



| |  |  | taking any action with respect to takeover defense measures, including with respect to our stockholder rights plan; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------



| |  |  | issuing or selling shares of our capital stock, other than issuances or sales after October 13, 2008 that may not exceed $25.0 million in any three-year
period, and other limited exceptions.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

These provisions could continue indefinitely and may limit our ability to enter
into transactions otherwise viewed as beneficial to us, which could cause the price of our common stock to decline.

Our stockholder
rights plan and anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us, which may be beneficial to our stockholders, more difficult.*

Provisions of our amended and restated certificate of incorporation and amended and restated bylaws, as well as provisions of Delaware law, could make it
more difficult for a third party to acquire us, even if doing so would benefit our stockholders. These provisions include, among others, provisions that:



| |  |  | authorize the issuance of blank check preferred stock that could be issued by our Board of Directors to increase the number of outstanding shares and
hinder a takeover attempt;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | limit who may call a special meeting of stockholders;
| | - |  | -----------------------------------------------------



| |  |  | prohibit stockholder action by written consent, thereby requiring all stockholder actions to be taken at a meeting of our stockholders; and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | establish advance notice requirements for nominations for election to our Board of Directors or for proposing matters that can be acted upon at stockholder
meetings.
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------

In addition, Section 203 of the Delaware General Corporation Law, which prohibits business combinations
between us and one or more significant stockholders unless specified conditions are met, may discourage, delay or prevent a third party from acquiring us.

We have adopted a rights agreement under which certain stockholders have the right to purchase shares of a new series of preferred stock at an exercise price of $40.00 per one one-hundredth of a share of such
preferred stock, subject to adjustment, if a person or group of persons acquires more than a certain percentage of our common stock. The rights plan could make it more difficult for a person to acquire a majority of our outstanding voting stock. The
rights plan could also reduce the price that investors might be willing to pay for shares of our common stock and result in the market price being lower than it would be without the rights plan. In addition, the existence of the rights plan itself
may deter a potential acquirer from acquiring us. As a result, either by operation of the rights plan or by its potential deterrent effect, mergers or other business combinations that our stockholders may consider in their best interests may not
occur.

The committed equity financing facility that we entered into with Kingsbridge may result in dilution to our stockholders.

Pursuant to the CEFF, Kingsbridge committed to purchase, subject to certain conditions and at our election, up to $75.0 million of
our common stock. Should we sell shares to Kingsbridge under the CEFF, or issue shares in lieu of any blackout payment, it will have a dilutive effect on the holdings of our current stockholders, and may result in downward pressure on
the price of our common stock. If we draw down amounts under the CEFF, we will issue shares to Kingsbridge at a discount of up to ten percent from the volume weighted average price of our common stock. If we draw down amounts under the CEFF when our
share price is decreasing, we will need to issue more shares to raise the same amount than if our stock price was higher. Issuances in the face of a declining share price will have an even greater dilutive effect than if our share price were stable
or increasing, and may further decrease our share price.

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

The trading price of our common stock has fluctuated significantly since our initial public offering in March 2004, and is likely to remain
volatile in the future. The trading price of our common stock could be subject to wide fluctuations in response to many events or factors, including the following:



| |  |  | announcements by us, Ipsen, Genentech, our suppliers and key third-party vendors, or our competitors of regulatory developments, product development agreements,
clinical trial results, clinical trial enrollment, regulatory filings, new products and product launches, significant acquisitions, strategic partnerships or joint ventures;
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | estimates of our business potential and earnings prospects;
| | - |  | -----------------------------------------------------------



| |  |  | deviations from analysts projections regarding business potential, costs and/or earnings prospects;
| | - |  | ----------------------------------------------------------------------------------------------------



| |  |  | developments with respect to our collaboration with Ipsen;
| | - |  | ----------------------------------------------------------



| |  |  | quarterly variations in our operating results;
| | - |  | ----------------------------------------------



| |  |  | significant developments in the businesses of biotechnology companies;
| | - |  | ----------------------------------------------------------------------



| |  |  | changes in financial estimates by securities analysts;
| | - |  | ------------------------------------------------------



| |  |  | changes in market valuations or financial results of biotechnology companies;
| | - |  | -----------------------------------------------------------------------------



| |  |  | additions or departures of key personnel;
| | - |  | -----------------------------------------



| |  |  | changes in the structure of healthcare payment or reimbursement systems, regulations or policies;
| | - |  | -------------------------------------------------------------------------------------------------



| |  |  | activities of short sellers and risk arbitrageurs;
| | - |  | --------------------------------------------------



| |  |  | future sales of our common stock, including potential sales of a substantial number of shares by Ipsen and its affiliates, or the perception that such sales are
likely to occur;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | general economic, industry and market conditions; and
| | - |  | -----------------------------------------------------



| |  |  | volume fluctuations, which are particularly common among highly volatile securities of biotechnology companies.
| | - |  | ---------------------------------------------------------------------------------------------------------------

In addition, the stock market has experienced volatility that has particularly affected the market prices of equity securities of many biotechnology
companies, which often has been unrelated or disproportionate to the operating performance of these companies. These broad market fluctuations may adversely affect the market price of our common stock. If the market price of our common stock
declines in value, you may not realize any return on your investment in us and may lose some or all of your investment.

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.

Substantial sales of shares may impact the market price of our common stock.*

If our stockholders sell substantial
amounts of our common stock, including shares issued upon the exercise of outstanding options or pursuant to the CEFF, and the shares issued or issuable to Genentech and Ipsen and its affiliates, the market price of our common stock may decline. In
addition, the perceived risk of dilution from sales or issuances of our common stock to or by Kingsbridge or Ipsen may cause holders of our common stock to sell their shares, or it may encourage short selling by market participants, which could
contribute to a decline in our stock price. These sales also might make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. We are unable to predict the effect that sales
may have on the prevailing market price of our common stock.

As of March 31, 2008, we had 51,583,550 outstanding shares of common
stock. As of March 31, 2008, we had 6,591,205 shares subject to outstanding options and restricted stock units granted under our equity compensation plans. In addition, as of March 31, 2008, 15,640,748 shares were issuable upon the
exercise of the warrant and conversion of the three convertible notes, which we have issued to Ipsen. Further, the terms of the warrant we issued to Ipsen provide that the number of shares of our common stock subject to the warrant may increase in
the event of certain issuances of equity securities by us that dilute Ipsens percentage ownership interest in us. Moreover, the initial exercise price of the warrant, and the conversion price of convertible notes we have issued to Ipsen, are
subject to certain weighted-average price-based antidilution adjustments. These terms of the warrant and convertible notes may entitle Ipsen to acquire a greater number of shares of our common stock than we currently anticipate.

##### Table of Contents

We have filed a registration statement covering shares of common stock issuable upon exercise of options
and other grants pursuant to our stock plans. In September 2005, we filed a shelf registration statement pursuant to which we may, from time-to-time, sell shares of our common stock and preferred stock, various series of debt securities and/or
warrants to purchase any of such securities, either individually or in units, in one or more offerings. In November 2005, we also filed a registration statement for the resale of the shares of common stock issuable in connection with the CEFF and
the shares of common stock underlying the warrant we issued to Kingsbridge in connection with our entering into the CEFF. Moreover, we have agreed that, upon Ipsens request, we would file one or more registration statements in order to permit
Ipsen and its affiliates to offer and sell a substantial number of shares of our common stock, including the 13,046,346 shares we issued to an affiliate of Ipsen and the shares issuable upon exercise of the warrant and conversion of the convertible
notes we issued to Ipsen. In addition, certain holders of shares of our common stock that are parties to our amended and restated investors rights agreement, including Genentech, are entitled to registration rights.

|ITEM 5. | OTHER INFORMATION.
|------- | ------------------

On February 26, 2008, our Board
of Directors amended the Tercica, Inc. 2004 Stock Plan, or the 2004 Plan, to provide for the grant thereunder of restricted stock unit awards. Prior to such amendment, the 2004 Plan provided for the grant of restricted stock awards, but not
restricted stock unit awards. Under the terms of the 2004 Plan, as amended, restricted stock unit awards may be granted under the 2004 Plan pursuant to restricted stock unit award agreements adopted by the plan administrator, generally our Board of
Directors or the Compensation Committee of the Board. Under the 2004 Plan, as amended, restricted stock unit awards may vest over the passage of time, the achievement of performance goals, or the occurrence of other events determined by the plan
administrator. Upon meeting vesting criteria applicable to a restricted stock unit award, a participant is entitled to receive a payout in the form of cash or shares of our common stock. The timing of such payments is determined by the plan
administrator. In addition, the plan administrator may permit participants to defer the payment of such payouts. Dividend equivalents may be credited in respect of shares of our common stock covered by restricted stock units, as determined by the
plan administrator and contained in the applicable restricted stock unit award agreement. The amendments to the 2004 Plan also effected certain technical amendments to the 2004 Plan, including with respect to compliance with Section 409A of the
Internal Revenue Code of 1986, as amended. The foregoing is only a brief description of the 2004 Plan amendments, does not purport to be complete and is qualified in its entirety by reference to the 2004 Plan, as amended, that is filed as Exhibit
10.3A to this quarterly report on Form 10-Q.
