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

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. See Note 3  Proposed Acquisition by Affiliates of Ipsen S.A. which describes the proposed merger agreement with Ipsen S.A.

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 six months ended June 30, 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, 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.

In general, the process for evaluating potential excess or obsolete inventory is not a complex process
and does not require significant management judgment. The factors considered in evaluating potential 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 the Companys 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 during which 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 throughout
2008. 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 June 30, 2008, the Company had total inventories of $26.3 million. The total inventory of $26.3 million at June 30, 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 rebates and discounts may require management judgment to estimate percentage of
eligible sales to these customers. 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 or facts and circumstances suggests a returns reserve is necessary.

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 provided 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 was 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
accounted for the conversion option as an embedded derivative that is bifurcated and measured separately from the convertible note (the host instrument). The note was denominated in Euros and the liability was 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 change in estimated fair value of embedded derivative 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 change in estimated fair value of embedded derivative 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. Following conversion of the note into the Companys common stock in accordance with its terms, the
carrying value of the host debt instrument will be reclassified into common stock and additional paid in capital. The changes in the fair value of the embedded conversion option from the last remeasurement date through the date of conversion will be
charged to current operations. See Note 11  Subsequent Events for a discussion regarding the conversion of this convertible note on July 22, 2008.

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 change in estimated
fair value of embedded derivative 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 10  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 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.

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 does not expect that the adoption of EITF 07-1 will 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 May 2008, the FASB issued SFAS No. 162, The Hierarchy of Generally Accepted Accounting Principles (SFAS No. 162). This standard is intended to improve financial reporting by identifying
a consistent framework, or hierarchy, for selecting accounting principles to be used in preparing financial statements that are presented in conformity with U.S. GAAP for non-governmental entities. SFAS No. 162 is effective 60 days following
the U.S. Securities and Exchange Commissions approval of the Public Company Accounting Oversight Board amendments to AU Section 411, the meaning of Present Fairly in Conformity with GAAP. 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. 162.

3. Proposed
Acquisition by Affiliates of Ipsen, S.A.

On June 4, 2008, the Company entered into an Agreement and Plan of Merger (the
Merger Agreement) with Beaufour Ipsen Pharma, a société par actions simplifiée organized under the laws of France (Parent) a wholly owned subsidiary of Ipsen, S.A. (Ipsen) and Tribeca
Acquisition Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent (Merger Sub) pursuant to which Parent would acquire all of the shares of Tercica common stock that Ipsen and its affiliates do not currently own at a
price of $9.00 per share in cash. Ipsen and Suraypharm, each of which are affiliates of Parent and Merger Sub, beneficially owned 42.7% of the Companys outstanding common stock as of June 30, 2008 (including shares of the Companys common
stock issuable upon the exercise and conversion of the then-outstanding warrant and convertible notes issued to Ipsen, but excluding shares subject to limited voting agreements that Ipsen and its affiliates entered into with certain of our other
stockholders). The Merger Agreement provides that, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will merge with and into the Company, with the Company as the surviving corporation of the merger (the
Merger). As a result of the Merger, the Company will become a wholly-owned subsidiary of Parent and its affiliates. The completion of the Merger is conditioned upon, among other things, the adoption of the Merger Agreement by the
Companys stockholders and the satisfaction or waiver of other closing conditions. Although the Merger is expected to close in the third or fourth quarter of 2008, there can be no assurances that the Merger will be completed within such time
frame, or at all. See Part II, Item 1A  Risk Related to the Merger.

At the effective time of the Merger, each
outstanding share of the Companys common stock (other than shares held by the Parent and its affiliates or by stockholders who have validly exercised appraisal rights) will be converted into the right to receive $9.00 per share in cash,
without interest, to be paid upon completion of the Merger.

The Merger Agreement may be terminated in certain circumstances, including in
the event that the Merger is not completed by January 1, 2009. The Merger Agreement requires the Company to pay Parent a termination fee in the amount of $11,000,000 if the Merger Agreement is terminated by either the Company or Parent in
connection with a change in the Companys Board of Directors recommendation that the Companys stockholders adopt the Merger Agreement, or if the Merger Agreement is terminated, there exist certain proposals or offers to acquire
Tercicas equity interests or assets by persons unaffiliated with Ipsen (Takeover Proposals), and within 12 months following the termination, Tercica enters into a contract providing for the implementation of a Takeover Proposal or
otherwise consummates a Takeover Proposal.

Upon execution of the Merger Agreement on June 4, 2008, Ipsen irrevocably agreed to
promptly convert all three of its outstanding convertible notes (see Note 6, Long-term Debt) into shares of the Companys common stock and to exercise its outstanding warrant to purchase shares of the Companys common stock. On
July 22, 2008, Ipsen fully converted all three of its convertible notes into shares of the Companys common stock and exercised its warrant to purchase shares of the Companys common stock (see Note 11, Subsequent Events).

The following is a summary of transaction related costs, recorded in general and administrative expenses, incurred in connection with the Merger for
the three months ended June 30, 2008 (in thousands). There were no costs incurred prior to April 1, 2008:

6. 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 accrued interest at a rate of
2.5% per year, compounded quarterly, and was convertible into the Companys common stock at a conversion price of $7.41 per share, subject to adjustment, which represented 3,526,373 shares at June 30, 2008.

In September 2007, the Company issued two additional convertible notes to Ipsen. The Second Convertible Note was payable in Euros in the
principal amounts of 30,000,000, or $41,640,000 on the date of issuance. The Third Convertible Note was payable in U.S. dollars in the principal amount of $15,000,000. The Second and Third Convertible Notes each accrued interest at
a rate of 2.5% per year, compounded quarterly, and were convertible into the Companys common stock at a conversion price of 5.92 per share for the Second Convertible Note and $7.41 per share for the Third Convertible Note,
which represented 5,167,865 and 2,064,356 shares, respectively, at June 30, 2008.

At the time of execution of the Merger Agreement,
Ipsen delivered a letter to the Company pursuant to which Ipsen irrevocably agreed to convert the Convertible Notes in full promptly following the execution of the Merger Agreement. On July 22, 2008, Ipsen fully converted the Convertible Notes
into shares of the Companys common stock (see Note 11, Subsequent Events).

The entire principal balance and accrued interest under
all the Convertible Notes was 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) notified the Company that it would not convert
the Convertible Notes in full, subject to Ipsens right to declare all amounts outstanding under the Convertible Notes immediately due and payable under certain circumstances.

Because the Second Convertible Note carried a conversion price per share stated in a foreign currency, the conversion feature constitutes a derivative
liability. The Company initially estimated the fair value of 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 is separately accounted for as a derivative liability and changes in estimated fair value are recorded in Change in estimated fair value of embedded derivative in
the condensed statement of operations for each period. This discount on the Second Convertible Note, as a result of this bifurcation, was being accreted to interest expense over four years using the effective interest method. The carrying value of
the Second Convertible Note on the date of issue was 20,780,000, or approximately $28,843,000, which is net of the discount. At June 30, 2008 the carrying value was 22,841,000, or $36,087,000, which approximates fair value.

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

As of June 30, 2008, the Company accrued $1,093,000 of cumulative interest expense on the
First Convertible Note, of which $162,000 and $323,000 were recorded as interest expense in the three and six months ended June 30, 2008, respectively. The amount payable under the First Convertible Note on October 13, 2011 would have been
$28,362,000, including cumulative interest of $3,325,000.

As of June 30, 2008, the Company recorded valuation adjustment gain of
$14,068,000 representing a decrease in value of the embedded derivative liability associated with the Second Convertible Note. This gain is included in Change in estimated fair value of embedded derivative in the condensed statements of
operations. The gain recorded was due to a shortened estimated remaining life of the Second Convertible Note which also changed other key inputs to the valuation of the embedded derivative liability reducing the fair value of the embedded derivative
liability. The Company accrued $889,000 of cumulative interest expense on the Second Convertible Note, of which $296,000 and $578,000 were recorded as interest expense in the three and six months ended June 30, 2008, respectively. The

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

Ipsen Warrant

Concurrently with the issuance of the First Convertible Note on October 13, 2006, the Company issued a warrant to purchase the Companys common stock to Ipsen (the Ipsen Warrant), which was 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 fluctuated throughout the term of the Ipsen Warrant. The number of shares of the Companys common stock issuable upon exercise of the Ipsen Warrant as of 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 Ipsen Warrant as of
June 30, 2008 was 4,948,795. The exercise term of the Ipsen Warrant was five years beginning on October 13, 2006, and the warrant was exercisable, in full or in part, at an exercise price of $7.41 per share. At the time of the execution of
the Merger Agreement, Ipsen delivered a letter to the Company pursuant to which Ipsen irrevocably agreed to promptly and fully exercise the Ipsen Warrant. On July 22, 2008, Ipsen exercised the Ipsen Warrant in full (See Note 11, Subsequent
Events).

8. 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
$1,577,000 and $1,635,000 was recorded during the three months ended June 30, 2008 and 2007, respectively, and $3,045,000 and $3,136,000 was recorded during the six months ended June 30, 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 term (years)   |  | 6.0                        |   |  | 6.0                      |   |  | 6.2  |   |  | 6.2  |

|Dividend yield          |  |                           |   |  |                         |   |  |     |   |  |     |  

The Companys computation of expected volatility for the three and six months ended
June 30, 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 and six
months ended June 30, 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 June 30, 2008, unrecognized stock-based compensation expense related to stock options of $11,878,000 was expected to be recognized over a
weighted-average period of 2.6 years.

Restricted Stock Units

In March 2008, the Company began to grant restricted stock units (RSUs) to eligible employees, executives and outside directors. 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 six months ended
June 30, 2008 was $5.96. As of June 30, 2008, unrecognized stock-based compensation expense related to non-vested RSUs of $1,367,000 was expected to be recognized over a weighted-average period of 3.5 years. Stock-based compensation
expense related to RSUs was approximately $78,000 and $73,000 for the three and six months ended June 30, 2008, respectively.

Stock-Based Award Modification

In June 2008, the Company modified an employees stock-based awards. The term of this employees modification includes the accelerated vesting
of stock-based awards outstanding on June 21, 2008. The employees stock-based awards will accelerate vest if the proposed Merger occurs prior to June 21, 2009. Since the proposed Merger had not closed as of June 30, 2008, no
additional compensation expense has been recognized to date. If the proposed Merger is completed, additional compensation expense related to the accelerated vesting of stock-based awards outstanding on June 21, 2008 would be recognized in the
Companys financial statements.

9. 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, RSUs 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.

10. Fair Value of Financial Instruments

Financial instruments 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.

##### Table of Contents

| |  |  | 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.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Fair valued liabilities that are generally included in this category are embedded derivative liabilities.

Fair Value on a
Recurring Basis

Assets and liabilities measured at fair value on a recurring basis are categorized in the tables below based upon the
lowest level of significant input to the valuations as of June 30, 2008 (in thousands):

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 June 30, 2008, and the related condensed statements of operations for the three and six month
periods ended June 30, 2008 and 2007, and the condensed statements of cash flows for the six month periods ended June 30, 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® (recombinant human insulin-like growth factor-1),
which is approved for marketing in the United States. the European Union, Israel and Taiwan;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Somatuline® Depot (extended release lanreotide), 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 a meeting held
on July 30, 2008 with the U.S. Food and Drug Administration, or FDA, preliminary data from this trial was discussed. These preliminary data suggest that the trial will meet its primary endpoint of statistically significant increase in
first-year height velocity compared to the observation-only group. As part of these discussions, however, the FDA requested additional long-term clinical data as part of the process for seeking approval from the FDA for marketing Increlex® for the treatment of short stature in children with Primary IGFD. Based on the FDAs request, we plan to review the regulatory strategy for Increlex® for the treatment of short stature in children with Primary IGFD.

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. Ipsen has launched Increlex® in Austria, Germany, Great Britain, Spain, Sweden,
Portugal, Italy, France, Denmark, the Netherlands, Norway, Poland and the Czech Republic, and expects to launch Increlex® in additional European countries during 2008.

Increlex® generated net product
revenues of $4.6 million and $8.0 million in the three and six months ended June 30, 2008, respectively. Net product revenues include supply revenues for Increlex® shipped to Ipsen of
$0.4 million and $0.7 million in the three and six months ended June 30, 2008 but excludes royalties paid to us by Ipsen on sales made by Ipsen in their territories.

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 from excess production of growth hormone typically due to a tumor in the pituitary gland, 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 $1.6 million and $2.6 million in the three and six months ended June 30, 2008, respectively.

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 June 30, 2008, we had approximately $71.4 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.

Proposed Acquisition
by Affiliates of Ipsen

On June 4, 2008, we entered into an Agreement and Plan of Merger, or the Merger Agreement, with Beaufour
Ipsen Pharma, a sociétépar actions simplifiée organized under the laws of France, or Parent, a wholly owned subsidiary of Ipsen, and Tribeca Acquisition Corporation, a Delaware
corporation and a wholly-owned subsidiary of Parent, or Merger Sub pursuant to which Parent would acquire all of the shares of Tercica common stock that Ipsen and its affiliates do not currently own at a price of $9.00 per share in cash. Ipsen and
Suraypharm, each of which are affiliates of Parent and Merger Sub, beneficially owned 42.6% of our outstanding common stock as of July 31, 2008 (including shares of our common stock issued upon exercise of a warrant and conversion of three
convertible notes, issued to Ipsen, but excluding shares subject to limited voting agreements that Ipsen and its affiliates entered into with certain of our other stockholders). The Merger Agreement provides that, upon the terms and subject to the
conditions set forth in the Merger Agreement, Merger Sub will merge with and into us, we will be the surviving corporation of the merger, or the Merger. As a result of the Merger, we will become a wholly-owned subsidiary of Parent and its
affiliates.

At the effective time of the Merger, each outstanding share of our common stock (other than shares held by the Parent and its
affiliates or by stockholders who have validly exercised appraisal rights) will be converted into the right to receive $9.00 per share in cash, without interest, to be paid upon completion of the Merger.

The Merger Agreement and the Merger were unanimously approved by our Board of Directors following the unanimous recommendation by a special committee of
our Board of Directors comprised of three independent non-employee directors. The special committee was advised by independent legal and financial advisors. The obligations of the parties to consummate the Merger are conditioned upon, among other
things, the adoption of the Merger Agreement by our stockholders and other closing conditions. Although the Merger is expected to close in the third or fourth quarter of 2008, there can be no assurances that the Merger will be completed within such
time frame, or at all. For more information on the risks and uncertainties related to the Merger, see Part II, Item 1A  Risk Related to the Merger.

The Merger Agreement may be terminated in certain circumstances, including in the event that the Merger is not completed by January 1, 2009. The Merger Agreement requires us to pay Parent a termination fee in the
amount of $11.0 million if the Merger Agreement is terminated under certain circumstances, as described in more detail in Note 3 Proposed Acquisition by Affiliates of Ipsen S.A. in the notes to our condensed financial statements.

In connection with the execution of the Merger Agreement certain officers and members of our Board of Directors entered into voting
agreements pursuant to which they have agreed to, among other things, vote in favor of the adoption of the Merger Agreement.

In addition, Parent obtained agreements from certain of its affiliates holding our common stock that each
of them shall vote, or cause to be voted, any shares of our common stock issued and outstanding on the date of the execution of the Merger Agreement that are beneficially owned by such affiliate or over which such affiliate has voting power, in
favor of adoption and approval of the Merger Agreement. The Merger agreement provides that Parent shall enforce its rights under these voting agreements to ensure that these stockholders vote or cause to be voted the common stock beneficially owned
by them to which they have the power in favor of the adoption of the Merger Agreement.

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 No. 157, Fair Value Measurements, or SFAS No. 157, 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 six months ended June 30, 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, or EITF. Issue 00-21 Revenue Arrangements with Multiple Deliverables, or 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.

##### 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:



| |  |  | 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 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 throughout 2008. 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 June 30, 2008, we had total inventories of $26.3 million. Total inventories
of $26.3 million 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.

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 change in estimated fair value of embedded derivative in our condensed statement of operations. 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 change in estimated fair value of embedded derivative in our condensed statements of operations.

On July 22, 2008, the convertible note denominated in Euros was converted in full by Ipsen into shares of our common stock as described in more detail in Note 11Subsequent Events in the notes to
our condensed financial statements.

Recent Accounting Pronouncements

In the first quarter of 2008, we adopted 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 10, Fair Value of Financial Instruments in the notes to our condensed financial statements. 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 June 2007, the FASB ratified EITF Issue No. 07-3, Accounting for Nonrefundable Advance
Payments for Goods or Services Received for Use in Future Research and Development Activities, or 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.

In
December 2007, the SEC issued SAB No. 110. SAB No. 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 No. 110. SAB No. 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 do not expect that the adoption of EITF 07-1 will 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 May 2008, the FASB issued SFAS No. 162,
The Hierarchy of Generally Accepted Accounting Principles, or SFAS No. 162. This standard is intended to improve financial reporting by identifying a consistent framework, or hierarchy, for selecting accounting principles to be used in
preparing financial statements that are presented in conformity with GAAP for non-governmental entities. SFAS No. 162 is effective 60 days following the U.S. Securities and Exchange Commissions approval of the Public Company Accounting
Oversight Board amendments to AU Section 411, the meaning of Present Fairly in Conformity with GAAP. 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. 162.

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 revenue from Ipsen for sales of Increlex® in the European Union.

Net Product Sales

Net product sales consist of gross Increlex® sales less provisions for discounts to customers, rebates to government agencies and other adjustments. The increase in net product sales in the three and six months ended June 30, 2008 compared to the same periods ended June 30,
2007 was primarily due to growth in Increlex® sales and launch of Somatuline® Depot in the United States.

Increlex® net product sales of $4.6
and $8.0 million for the three and six months ended June 30, 2008 increased by $2.6 million and $4.9 million for the three and six months ended June 30, 2008, respectively, as compared to the same periods in 2007. The growth of
Increlex® net product sales was primarily due to continued expansion of our patient base. In the fourth quarter of 2007, we began shipment of Increlex® to Ipsen for commercial distribution in the European Union, which added $0.4 million and $0.7 million to net product sales in the three and six months ended June 30, 2008, respectively. In the same periods in
2007, we did not record any Increlex® sales for shipments to Ipsen.

##### Table of Contents

In November 2007, we launched Somatuline® Depot in the United States, which added $1.6 million and $2.6 million to net product sales in the three and six months ended June 30, 2008, respectively. In the same periods in 2007, we
did not record any Somatuline® Depot sales in the United States.

We expect both Increlex® and
Somatuline® Depot net 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 period over period basis as we experienced in the three and six months ended June 30, 2008 as compared to the same periods in 2007.

License Revenue

License revenue represents amortization of the upfront license payment in connection with our
Increlex® license and collaboration agreement with Ipsen which was $0.2 million and $0.4 million for both of the three and six months ended June 30, 2008 and 2007, respectively. 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; however, we are unable to predict the timing or the likelihood of any such payments.

Royalty Revenue

We recorded royalty revenue of $0.1 million and $0.2 million in the three and six months ended
June 30, 2008, respectively, from sales of Increlex® in the European Union by Ipsen. In the same periods in 2007, we did not record royalties on sales of Increlex® in the European Union by Ipsen. We expect our royalty revenues to increase over the next several quarters as Ipsen continues to expand its 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 inventory and failed drug substance batches, as well as 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 and six months ended June 30, 2008 increased $2.4 million and $5.1 million, respectively, over the same periods 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 and six months ended
June 30, 2008, the cost of Increlex® sales were $2.9 million and $5.7 million, respectively, and the cost of Somatuline®
Depot sales were $0.6 million and $1.0 million, respectively.

Cost of sales as a percentage of net product sales in the three months ended
June 30, 2008 was lower than in the same period in 2007 primarily due to raw material expense associated with failed drug substance batches in the second quarter of 2007 partially offset by higher absorption of personnel and other costs
recorded to cost of sales in the second quarter of 2008.

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 the
cost of new manufacturing equipment will be owned by our contract manufacturer.

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 increases in the three and six months ended June 30, 2008 were primarily due to the increases in manufacturing activities at both facilities in the first and second quarters of 2008 compared to the first and second quarters of 2007.
Substantially all the transfer activities for fill and finish operations have been incurred and the majority of costs borne by us associated with drug substance transfer have also been incurred. Project activity will continue throughout 2008, and
there will be costs that will continue through the end of 2008 associated with engineering and validation runs 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.

The $5.4 million and $11.5 million in research
and development expenses for the three and six months ended June 30, 2008, respectively, were comprised of personnel and related costs of $3.1 million and $6.5 million, respectively, third-party contract costs related to our clinical activities
for Increlex® Primary IGFD and severe Primary IGFD of $1.2 million and $2.7 million, respectively, clinical activities associated with growth hormone/IGF-1 combination product candidates of
$0.8 million and $1.7 million, respectively, and Somatuline® Depot clinical activities in acromegaly of $0.3 million and $0.6 million, respectively.

During the three and six months ended June 30, 2008, research and development expenses
increased as compared to the same periods in 2007 primarily due to an increase in third party contractor costs of $1.0 million and $1.7 million, and payroll related costs of $0.3 million and $0.8 million, respectively The increases in third-party
contractor costs in 2008 were primarily due to increases in clinical activities associated with growth hormone/IGF-1 combination product candidates as well as the Increlex® product
registry, partially offset by decreases in activities associated with our European marketing authorization application, or MAA. The increases in payroll related costs in 2008 were primarily due to increased personnel compared to 2007.

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 compassionate-use free drug, professional services including legal and accounting services, medical education and other administrative costs.

We incurred $15.5 million and $27.9 million in selling, general and administrative expenses for the three and six months ended June 30, 2008,
respectively. Excluding $1.4 million of expenses associated with the Merger, selling, general and administrative expenses for the three and six months ended June 30, 2008 were comprised of payroll and related costs of $7.8 million and $14.9
million, respectively, sales and marketing activities, including cost of compassionate-use free drug, of $3.3 million and $6.6 million, respectively, medical education activities of $1.7 million and $2.4 million, respectively, legal, accounting and
other professional services of $1.0 million and $2.0 million, respectively, and other general administrative activities of $0.3 million and $0.6 million, respectively.

Excluding the $1.4 million of expenses recorded in the second quarter of 2008 associated with the
Merger, during the three and six months ended June 30, 2008, selling, general and administrative expenses increased $3.8 million and $6.7 million, respectively, as compared to the same periods in 2007 primarily due to an increase in payroll and
related costs of $1.4 million and $2.1 million, respectively, increase in medical education expense of $1.2 million and $1.9 million, respectively, increase in sales and marketing expenses of $1.0 million and $2.9 million, respectively, and an
increase in other general administrative activities of $0.2 million for the three months ended June 30, 2008 and a decrease of $0.2 million for the six months ended June 30, 2008. The expenses associated with the Merger were due to
advisor, legal and accounting service fees. The increase in sales and marketing activities was primarily related to increased costs associated with product promotions, 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. The increase in medical education expenses were primarily related to increases in activities in support of Increlex® and
Somatuline® Depot.

We expect total selling, general and administrative
expenses to increase modestly, excluding the costs associated with the Merger, for the remainder of 2008 compared to those recorded in the three and six months ended June 30, 2008. We expect to incur additional expenses associated with the
Merger.

Amortization of Intangible Assets

Amortization of intangible assets of $0.7 million and $1.4 million in the three and six months
ended June 30, 2008, respectively, 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 periods in 2007.

Interest Expense

Interest expense of $1.3 million and $2.6 million for the three and six months ended June 30, 2008, respectively, increased $1.1 million and $2.2
million as compared to the same periods in 2007, respectively. The increase in 2008 was primarily due to the timing of issuance of two convertible notes to Ipsen in September 2007. The first convertible note was issued to Ipsen in October 2006.

We expect interest expense to decrease significantly as Ipsen exercised the three convertible notes in full on July 22, 2008 as
described in more detail below under Ipsen Collaboration and in Note 11Subsequent Events in the notes to our condensed financial statements.

Change in Estimated Fair Value of Embedded Derivative

Change of estimated fair value of
embedded derivative of $13.7 million and $11.7 million in the three and six months ended June, 30 2008, respectively, 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. This convertible note was denominated in Euros and the conversion option was considered an embedded derivative. The fair value of the embedded conversion option is estimated at the end of each reporting period and
changes in value are recorded, which resulted in a gain of $9.8 million and $14.1 million in the three and six months ended June 30, 2008, respectively. The gain recorded was due to a shortened estimated remaining life of this convertible note
which also changed other key inputs to the valuation of the embedded derivative liability reducing the fair value of the embedded derivative liability. Further, this convertible note is revalued to U.S. dollars at the end of each reporting period,
which resulted in a charge of $9,000 and $2.4 million in the three and six months ended June 30, 2008, respectively. There were no such charges or benefits recorded for the same periods in 2007.

On July 22, 2008, Ipsen exercised the convertible notes and, as such, we will not record further adjustments related to the Euro denominated
convertible note or associated embedded derivative as described in more detail in Note 11Subsequent Events in the notes to our condensed financial statements.

Interest and Other Income, net

Interest and other income, net of $0.6 million and $1.7 million for the three and six months ended June 30, 2008, respectively, decreased $0.8 million and $1.3 million as compared to the same periods in 2007. The decreases were
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 a modest increase in net interest and other income for the remainder of 2008 as we
will have higher balances of cash and short-term investments primarily due to cash received in connection with the exercise of a warrant by Ipsen, offset by our use of those higher cash and short-term investments to fund our operations.

Provision for Income Taxes

The provision for income taxes recorded in the three and six months ended June 30, 2008,
represent French foreign income taxes paid on royalties paid to us by Ipsen under our Increlex® license and collaboration agreement with Ipsen. There were no income taxes paid for the same
periods 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 and six months ended June 30, 2008
and 2007 because we have incurred operating losses to date.

Liquidity and Capital Resources

Sources of Liquidity

As of
June 30, 2008, we had approximately $71.4 million in cash, cash equivalents and short-term investments. We had an accumulated deficit of $318.1 million, which was primarily comprised of $274.0 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 June 30, 2008 primarily from issuance of equity, convertible notes and
the receipt of up-front and milestone payments under our collaboration with Ipsen. Through June 30, 2008, we had 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.

On July 11, 2008, we received $4.0
million from Genentech in connection with the issuance of additional shares of our common stock, and on July 22, 2008, we received $40.4 million from Ipsen in connection with the exercise of a warrant and the issuance of additional shares of
our common stock. These events are described in more detail below in Ipsen Collaboration, Genentech Combination Product Collaboration and in Note 11Subsequent Events in the notes to our condensed financial
statements.

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 was exercisable at any time during the five-year period after the initial closing and carried 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 had a maturity date on the later of October 13, 2011 or two years from the
date of notification of non-convert and carried a coupon of 2.5% per annum from the date of issuance, compounded quarterly, and was 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). On July 22, 2008, Ipsen converted the convertible notes and exercised the warrant in full as described in more detail below.

On July 22, 2008, we entered into a common stock purchase agreement, or the Ipsen Purchase Agreement, with Ipsen and Suraypharm (an affiliate of
Ipsen) pursuant to which we sold to Ipsen 410,831 shares of our common stock, or the Ipsen Shares, for an aggregate cash purchase price of $3.7 million. The Ipsen Shares were issued and sold to Ipsen at a price per share of $8.92, which equals the
consolidated closing bid price of our common stock as reported by NASDAQ on July 21, 2008. Under the terms of the affiliation agreement we entered into with Ipsen and Suraypharm in October 2006, Suraypharm has a right of first offer to purchase
up to its pro rata portion of new equity securities offered by us (subject to certain exceptions). Ipsen, as Suraypharms designated affiliate, acquired the Ipsen Shares in exercise of Suraypharms pro rata right under the
Affiliation Agreement with respect to the sale and issuance of 590,580 shares of our common stock to Genentech on July 11, 2008 as described below.

Also on July 22, 2008, we issued an aggregate of 10,774,806 shares of our common stock in connection with the election by Ipsen to convert in full the entire outstanding principal and accrued interest under the
convertible notes, as follows:



| |  |  | First Senior Convertible Promissory Note, dated October 13, 2006 with an outstanding principal and accrued interest balance of $26.2 million at July 22,
2008, was converted at a conversion price per share of $7.41, for a total of 3,531,687 shares of our common stock;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Second Senior Convertible Promissory Note, dated September 17, 2007 with an outstanding principal and accrued interest balance of 30.6 million at
July 22, 2008, was converted at a conversion price per share of 5.92, for a total of 5,175,652 shares of our common stock; and
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Third Senior Convertible Promissory Note, dated September 17, 2007 with an outstanding principal and accrued interest balance of $15.3 million at July 22,
2008, was converted at a conversion price per share of $7.41, for a total of 2,067,467 shares of our common stock.
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Further, on July 22, 2008, we also issued 4,948,795 shares of our common stock, or Warrant Shares, to Ipsen upon the exercise in full of its warrant dated October 13, 2006. The Warrant Shares were issued to Ipsen upon exercise of
its warrant at a cash exercise price per share of $7.41, for total cash proceeds to us of $36.7 million.

After giving effect to the
conversion of the convertible notes, the exercise of the warrant and the acquisition of the Ipsen Shares, as of July 31, 2008, Ipsen and its affiliates beneficially owned 42.6% of our common stock (not including shares subject to limited voting
agreements that Ipsen and its affiliates entered into with certain of our other stockholders).

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

##### Table of Contents

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 or that the Merger will be completed. The
completion of the Merger is conditioned upon, among other things, the adoption of the Merger Agreement by our stockholders and the satisfaction or waiver of other closing conditions. Therefore, the Merger may not be completed or may not be completed
in a timely manner. For more information on these and other risks and uncertainties related to our collaboration with Ipsen, see the sections entitled Risks Related to the Merger, 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 in July 2007, or the Genentech Purchase Agreement, resulting in gross cash proceeds of approximately $4.0 million during 2007.

On July 11, 2008 and as described in more detail in Note 11Subsequent Events in the notes to our condensed financial statements, we received a cash payment in connection with this combination product agreement and
issued 590,580 shares of our common stock to Genentech at price per share of $6.773 pursuant to the Genentech Purchase Agreement, resulting in an additional gross cash proceeds of approximately $4.0 million. We may issue up to an additional
1,052,632 shares of common stock (or up to a maximum of $5.0 million of shares of common stock) to Genentech pursuant to the Genentech 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. 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



29

##### Table of Contents

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 $71.4 million at June 30, 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 $43.0 million offset by cash provided by net sales of
short-term investments as discussed below.

Operating Activities

Net cash used in operating activities totaled $43.0 million in the six month period ended
June 30, 2008. Cash used in operating activities during 2008 was primarily driven by our net losses from operations of $28.9 million, increases in inventory of $12.3 million, adjusted for the non-cash stock-based compensation charge of $3.0
million related to SFAS No. 123R and a net non-cash benefit of $11.7 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 and accounts payable which totaled
$5.1 million.

Investing Activities

Net cash provided by investing activities totaled $30.0 million in the six month period ended June 30, 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 $0.7 million in the six month period ended June 30, 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 June 30, 2008, together with cash received subsequent to June 30, 2008, as described above, will be sufficient to meet our projected operating and
capital expenditure requirements through at least June 30, 2009, based on our current business plan and if the Merger is not completed. If the merger agreement is terminated under certain circumstances, we may be obligated to pay to Beaufour
Ipsen Pharma, an affiliate of Ipsen, a termination fee of $11.0 million. Further, if the Merger is not completed, 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 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, if the Merger is not completed. 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 the Genentech Purchase Agreement pursuant to which we may issue up to an additional 1,052,632 shares of common stock (or up to a maximum of $5.0 million of shares of common stock) to
Genentech, such issuance is subject to various conditions, including the achievement of a regulatory approval milestone, and there can be no assurance that we will receive additional funds from Genentech pursuant to the Genentech Purchase Agreement.
If additional funds are not available, we may be forced to curtail or cease operations.

Contractual Obligations and Commercial
Commitments

During the six-month period ended June 30, 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 with the exception of the contingent obligation to pay Lehman Brothers Inc., the financial advisor to the Special Committee of the Board of Directors in
connection with the Merger, a financial advisory fee of approximately $3.4 million which is contingent upon closing of the Merger. Additionally, we may increase the financial advisory fee by up to $2.0 million at our discretion if, in the judgment
of the Special Committee of our Board of Directors, Lehman Brothers role, the importance of Lehman Brothers expertise, the outcome of the transaction, Lehman Brothers contribution to the results obtained, and the intensity and
duration of Lehman Brothers efforts, warrants such an increase.



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

As of June 30, 2008, there were no material changes to our disclosures to market risk from the disclosures set forth under the caption, Quantitative and Qualitative Disclosures About Market Risk in Part II, Item 7A, of
our Annual Report on Form 10-K for the year ended December 31, 2007. For more information on the conversion of our convertible notes, see Note 11  Subsequent Events in the notes to our condensed financial statements.

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

Evaluation of
Disclosure Controls and Procedures

Based on their evaluation as of June 30, 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 June 30, 2008 that have materially affected, or are reasonably likely to materially affect, our internal control
over financial reporting.

##### Table of Contents

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 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. In addition, the risks described under, and the caption entitled, 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, included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission on February 29, 2008 have been removed.

Risks Related to the Merger

If the merger is
not completed, or not completed in a timely manner, our business would be significantly harmed, and our stock price would likely decline significantly.*

The completion of the merger is conditioned upon, among other things, the adoption of the merger agreement by our stockholders and the satisfaction or waiver of other closing conditions. Therefore, the merger may not
be completed or may not be completed in a timely manner. If the merger agreement is terminated, the market price of our common stock will likely decline. In addition, our stock price may decline as a result of the fact that we have incurred and will
continue to incur significant expenses related to the merger prior to its closing that will not be recovered if the merger is not completed. As of June 30, 2008, we had incurred a total of approximately $1.4 million in expenses related to the merger
and expect to incur a total of approximately $4.9 million in expenses related to the merger, not including the potential increase to the financial advisory fee payable to Lehman Brothers of up to $2.0 million if, in the judgment of the Special
Committee of our Board of Directors, the circumstances warrant such an increase. If the merger agreement is terminated under certain circumstances, we may be obligated to pay to Beaufour Ipsen Pharma, an affiliate of Ipsen, a termination fee of
$11.0 million. As a consequence of the failure of the merger to be completed, as well as of some or all of these potential effects of the termination of the merger agreement, our business could be harmed. Concerns about our viability are likely to
increase, thereby likely making it more difficult to retain employees, maintain existing business and strategic relationships, including with Ipsen, and to effectively pursue new business development opportunities.

The fact that there is a merger pending could harm our business, revenue and results of operations.*

While the merger is pending, it creates uncertainty about our future, and we are subject to a number of risks that may harm our business, revenue and
results of operations, including:



| |  |  | the diversion of management and employee attention;
| | - |  | ---------------------------------------------------



| |  |  | the unavoidable disruption to our business relationships, including relationships with suppliers and manufacturers, which may detract from our ability to grow
revenues and minimize costs;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the possible loss of strategic relationships or business development opportunities;
| | - |  | -----------------------------------------------------------------------------------



| |  |  | the incurrence of significant expenses related to the merger prior to its closing;
| | - |  | ----------------------------------------------------------------------------------



| |  |  | our weakened ability to respond effectively to competitive pressures, industry developments and future opportunities;
| | - |  | ---------------------------------------------------------------------------------------------------------------------



| |  |  | the possible loss of employees; and
| | - |  | -----------------------------------



| |  |  | the inability to hire new employees.

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 June 30, 2008, we had an accumulated deficit of
$318.1 million. We incurred a net loss of $28.9 million during the six months ended June 30, 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 Insulin-like Growth Factor
Deficiency (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® (recombinant human insulin-like growth factor-1) 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;
| | - |  | --------------

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. For instance, in a meeting held on July 30, 2008 with the FDA, preliminary data from our
Phase IIIb clinical trial for the use of Increlex® for the treatment of Primary IGFD was discussed. As part of these discussions, the FDA requested additional long-term clinical data as
part of the process for seeking approval from the FDA for marketing Increlex® for the treatment of Primary IGFD. Based on the

##### Table of Contents

FDAs request, we plan to review the regulatory strategy for 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.

While we have entered into the Merger Agreement with Beaufour Ipsen Pharma, an affiliate of Ipsen,
the completion of the Merger is subject to a number of conditions. In the event that the Merger is not completed, we will continue to be subject to a number of risks with respect to our collaboration with Ipsen. Even though Somatuline® Depot (extended release lanreotide) 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.

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, Adult Growth Hormone Deficiency (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,



34

##### Table of Contents

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;
| | - |  | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | contract laboratories fail to follow good laboratory practices;
| | - |  | ---------------------------------------------------------------



| |  |  | suppliers, supply partners, and/or contract manufacturers fail to follow good manufacturing practices;
| | - |  | ------------------------------------------------------------------------------------------------------



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



| |  |  | clinical trial drug supplies are not available, are not available in sufficient quantities, are not available in the preferred formulation, or available drug
becomes 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.

##### Table of Contents

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.

While we have entered into the
Merger Agreement with Beaufour Ipsen Pharma, an affiliate of Ipsen, the completion of the Merger is subject to a number of conditions. In the event that the Merger is not completed, we will continue to be subject to a number of risks related to our
relationship with Ipsen. 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
| | - |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | the collaborations may be terminated or allowed to expire, which would delay product development and commercialization efforts.

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.

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.

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



38

##### Table of Contents

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 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 or 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

##### Table of Contents

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.

##### Table of Contents

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:



| |  |  | some patent applications in the United States may be maintained in secrecy until the patents are issued,
| | - |  | --------------------------------------------------------------------------------------------------------



| |  |  | patent applications in the United States and many foreign jurisdictions are typically not published until 18 months after filing, and
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------



| |  |  | 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.*

While we have entered into the Merger Agreement with Beaufour Ipsen Pharma, an
affiliate of Ipsen, the completion of the Merger is subject to a number of conditions. In the event that the Merger is not completed, we will continue to be subject to a number of risks related to our relationship with Ipsen. As of July 31,
2008, Ipsen and its affiliates beneficially owned approximately 42.6% of our common stock (not including shares subject to limited voting agreements that Ipsen and its affiliates entered into with certain 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. Accordingly, our
other stockholders may be unable to prevent actions taken by Ipsen. 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.

##### Table of Contents

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 all of the indications licensed to us under the agreement. 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 of the indications licensed to us under the agreement. Following an opt-in by Genentech, Genentech would control the
joint development and commercialization of the combination product candidates and products for all of the indications licensed to us under the agreement other than AGHD and short stature 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;
| | - |  | ---------------------

##### Table of Contents

| |  |  | 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.

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 June 30, 2008 will
be sufficient to meet our projected operating and capital expenditure requirements through at least June 30, 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;
| | - |  | ---------------------------------------------------------------------------------------------------------------------------



| |  |  | 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 1,052,632 shares of common stock (or up to a maximum of $5.0 million of shares of common stock) to Genentech, such
issuance is subject to various conditions, including 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 June 30, 2008, we
had 141 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 July 31, 2008, our directors, executive officers and principal stockholders and their affiliates beneficially owned approximately 68.3% of
our common stock. Our greater than five percent beneficial owners include Ipsen and its affiliates, which beneficially owned 42.6% (not including shares subject to limited voting agreements that Ipsen and its affiliates entered into with certain of
our other stockholders); entities affiliated with MPM BioVentures III LLC, which beneficially owned 13.3%; entities affiliated with Prospect Management Co. II, LLC, which beneficially owned 5.9%; 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;
| | - |  | ---------------------------------------------



| |  |  | 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. In connection with the execution and delivery of the merger agreement with affiliates of Ipsen, we entered into an
amendment to the rights agreement in order to, among other things, prevent the merger agreement, the merger contemplated by the merger agreement or the consummation of any other transactions contemplated by the merger agreement from triggering the
distribution and/or exercise of the rights under the rights agreement. If the merger contemplated by the merger agreement is not completed, 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 if the merger is not completed,
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 (other than the merger) 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;

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



| |  |  | 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 July 31, 2008, we had 68,464,752 outstanding shares of common
stock. As of July 31, 2008, we had 6,749,580 shares subject to outstanding options and restricted stock units granted under our equity compensation plans.

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 29,180,778 shares we issued to Ipsen and an affiliate of 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 May 19, 2008, the
Compensation Committee of our Board of Directors approved an amendment to the employment letter agreement (the Employment Agreement Amendment) of Thorsten von Stein, Ph.D., M.D., our Chief Medical Officer and Senior Vice President of
Clinical and Regulatory Affairs, to provide that in the event that Dr. von Stein is terminated without cause or terminates his own employment for good reason within 12 months following a change of control, as these terms are defined in his
employment agreement, Dr. von Stein will, subject to his entering into an effective release of claims in our favor, be entitled to receive a lump-sum severance payment equal to one year of his base salary in effect as of his termination date
and the vesting of his stock options and restricted stock unit awards will be accelerated in full. Prior to the Employment Agreement Amendment, Dr. von Stein was entitled to a lump-sum severance payment equal to six months of his base salary
and the accelerated vesting of 50% of his stock options and restricted stock unit awards, in the event that he is terminated without cause or terminates his own employment for good reason within 12 months following a change of control. The foregoing
is only a brief description of the Employment Agreement Amendment, does not purport to be complete and is qualified in its entirety by reference to the Employment Agreement Amendment that is filed as Exhibit 10.9DD to this quarterly report on Form
10-Q.
