NOTES TO FINANCIAL STATEMENTS

(unaudited)

1.	Basis of presentation

The accompanying unaudited financial statements of ZymoGenetics, Inc. (the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and the instructions to Form 10-Q. Certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles have been omitted pursuant to such rules and regulations. In the opinion of management, the financial statements reflect all normal recurring adjustments necessary to present fairly the Company’s financial position and results of operations as of and for the periods indicated. Operating results for such periods are not necessarily indicative of the results that may be expected for the full year or for any future period.

The December 31, 2006 balance sheet data was derived from the audited financial statements at that date but does not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. These unaudited interim financial statements should be read in conjunction with the audited financial statements and related footnotes included in the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2006.

The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and that affect the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

2.	Net loss per share

Basic and diluted net loss per share has been computed based on net loss and the weighted-average number of common shares outstanding during the applicable period. The Company has excluded 13.0 million outstanding options to purchase common stock as such shares are antidilutive for all periods presented.

3.	Short-term investments

Short-term investments consisted of the following at March 31, 2007 (in thousands):


	Amortized Cost		Gross Unrealized Gain		Gross Unrealized Loss			Estimated Fair Value
Type of security:
Corporate debt securities	$	71,040	$	69	$	(45	)	$	71,064
Asset-backed securities		103,706		74		(408	)		103,372
U.S. government and agency securities		24,302		5		(33	)		24,274

	$	199,048	$	148	$	(486	)	$	198,710

Maturity date:
Less than one year	$	125,168						$	124,856
Due in 1-3 years		73,880							73,854

	$	199,048						$	198,710

The Company’s management has concluded that unrealized losses are temporary, as the duration of the decline in the value of the investments has been relatively short; the extent of the decline, both in dollars and percentage of cost is not severe; and the Company has the ability and intent to hold the investments until at least substantially all of the cost of the investments is recovered.

4.	Stock compensation

A summary of the fully vested stock options currently exercisable as of March 31, 2007 is presented below (shares and aggregate intrinsic value in thousands):


	Shares	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value
Exercisable, March 31, 2007	7,522	$	10.37	5.6	$	46,593

The Company recorded the following amounts of stock-based compensation expense for the three-month periods ended March 31 (in thousands):


	2007		2006
Research and development expense	$	3,556	$	2,899
General and administrative expense		1,895		1,619

Total	$	5,451	$	4,518

No income tax benefit has been recorded as the Company has a full valuation allowance and management has concluded it is more likely than not that the net deferred tax asset will not be realized. As of March 31, 2007, there were $45.6 million of total unrecognized compensation costs related to stock options. These costs are expected to be recognized over a weighted average period of approximately three years.

Estimated fair values of stock options granted have been determined using the Black-Scholes option pricing model with the following assumptions for the three-month periods ended March 31:


	2007		2006
Expected stock price volatility	55	%	56	%
Risk-free interest rate	4.54	%	4.40	%
Expected life of options	6.1 years		6.1 years
Expected dividend yield	0	%	0	%

5.	Comprehensive loss

For the three months ended March 31, 2007 and 2006, total comprehensive loss was $32.5 million and $32.0 million, respectively. Comprehensive loss is composed of net loss and unrealized gains and losses on short-term and long-term investments. The net change in accumulated other comprehensive gain for the three months ended March 31, 2007 was $849,000, reflecting a $287,000 increase in net unrealized gains on short-term investments due to decreasing interest rates and an increase of $562,000 in unrealized gain on long-term investments due to an increase in market value.

6.	Accounting for uncertainty in income taxes

On January 1, 2007, the Company adopted Financial Accounting Standards Board Interpretation No. 48 “Accounting for Uncertainty in Income Taxes” (FIN 48). FIN 48 prescribes a recognition threshold that a tax position is required to meet before being recognized in the financial statements.

Historically, the Company’s tax provision for financial statement purposes and the actual tax returns have been prepared using consistent methodologies. As of December 31, 2006, there were no material unrecognized tax benefits. Due to the Company’s net operating loss carryforwards, any future adjustments to the unrecognized tax benefit will have no impact on the Company’s effective tax rate due to the valuation allowance which fully offsets all tax benefits. For the quarter ended March 31, 2007, the unrecognized tax benefit change was immaterial and the Company does not expect significant changes during the next twelve months. Any interest and penalties incurred on the settlement of outstanding tax positions would be recorded as a component of interest expense.

The Company files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. The Company’s Federal and state taxes for the years 2000 through 2006 are subject to examination. The Company believes any assessments would be immaterial to its financial statements.

7.	Recent accounting pronouncements

In September 2006, the Financial Accounting Standards Board (FASB) issued FASB Statement No. 157 Accounting for Fair Value Measurements (FAS 157). FAS 157 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles (GAAP), and expands disclosures about fair value measurements. FAS 157 applies under other accounting pronouncements that require or permit fair value measurements, the FASB having previously concluded in those accounting pronouncements that fair value is the relevant measurement attribute. Accordingly, FAS 157 does not require any new fair value measurements. FAS 157 is effective for financial statements issued for fiscal years beginning after November 15, 2007 and interim periods within those fiscal years. The Company is currently assessing the financial impact of FAS 157 on its results of operations, cash flows and financial condition, but does not expect that its adoption will have a material impact.

8.	Contingencies

The Company has a license agreement with a third party under which the Company is obligated to pay royalties based upon the application of an agreed-upon formula, which contains certain variables that are subject to interpretation. Through March 31, 2007, the Company has recorded approximately $229,000 in royalty expense, which it believes fully satisfied its obligation under the license agreement. In the fourth quarter of 2005, the other party claimed that the Company owes a total of $2.0 million under its interpretation of the royalty formula. The Company continues to believe that its method of calculating the amount of royalties due is valid and intends to vigorously defend its position. The Company has applied SFAS No. 5, Accounting for Contingencies, to this matter and has concluded that it is not required to record a liability.

In 2006, the Company and one of its collaborative partners, Merck Serono, agreed to an increase in the overhead rate charged by Serono for manufacturing activities performed in support of the atacicept development program. However, the parties have not reached agreement on the effective date of the change. Merck Serono asserts that the Company is obligated to pay manufacturing overhead based on the new methodology for the full year 2006, which would be approximately $3.6 million. The Company believes that, based on the governance mechanisms contained in the collaborative agreement, the obligation did not begin until the fourth quarter of 2006, and the amount owed should be approximately $900,000. The parties are seeking an amicable resolution; however, no agreement has been reached. The Company has applied SFAS No. 5, Accounting for Contingencies, to this matter and accordingly, has recorded $900,000 as research and development expense through March 31, 2007, related to this matter.

Item 2.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

The following discussion and analysis should be read in conjunction with the financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q. This report contains, in addition to historical information, forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve risks and uncertainties. This Act provides a “safe harbor” for forward-looking statements to encourage companies to provide prospective information about themselves so long as they identify these statements as forward-looking and provide meaningful cautionary statements identifying important factors that could cause actual results to differ from the projected results. Factors that could cause or contribute to such differences include, but are not limited to, risks associated with our preclinical and clinical development, regulatory oversight, intellectual property claims and litigation and other risks detailed in our public filings with the Securities and Exchange Commission, including those risks described in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2006. All statements other than statements of historical fact, including statements regarding industry prospects and future results of operations or financial position, made in this Quarterly Report on Form 10-Q are forward looking. When used in this document, the words “believes,” “expects,” “anticipates,” “intends,” “plans” and similar expressions, are intended to identify certain of these forward-looking statements. However, these words are not the exclusive means of identifying such statements. In addition, any statements that refer to expectations, projections or other characterizations of future events or circumstances are forward-looking statements. The cautionary statements made in this document should be read as being applicable to all related forward-looking statements wherever they appear in this document. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this report. We undertake no obligation to revise any forward-looking statements in order to reflect events or circumstances that may subsequently arise. Readers are urged to carefully review and consider the various disclosures made in this report and in our other reports filed with the Securities and Exchange Commission that attempt to advise interested parties of the risks and other factors that may affect our business, prospects and results of operations.

Business Overview

We are a biopharmaceutical company focused on discovering, developing and commercializing therapeutic protein-based products for the treatment of human diseases. The process for taking one of our discoveries to the marketplace is long, complex and very costly. It is difficult to predict the time it will take to commercialize any given product candidate, but it would not be unusual to span ten years or more and cost hundreds of millions of dollars. It is also a business of attrition; it is expected that, for the industry as a whole, less than 20% of the drug candidates entering human clinical trials will actually make it to the marketplace. For the products that do make it, particularly for those that address previously unmet medical needs, the markets can be significant, with a number of successful products selling in excess of $1 billion per year.

An important element of our strategy is that we intend to maintain all or a significant share of the commercial rights to a number of our product candidates in North American markets. As a result, we will be required to pay a significant portion of the development costs for these product candidates. A second important element of our strategy is that we are developing a broad portfolio of product candidates to give our company more opportunities to be successful. We currently have four product candidates in clinical development and expect to add additional proteins to this portfolio in the future. Thus, we are paying a significant portion of development costs for several potential products. Assuming these product candidates progress through clinical development successfully, the costs of clinical trials are expected to increase significantly.

Our most significant financial challenges are to obtain adequate funding to cover the cost of product development, and to control spending and direct it toward product candidates that will create the most value for our shareholders over the long term. It can be a complex and highly subjective process to establish the appropriate balance between cash conservation and value generation. There are a number of important factors that we consider in addressing these challenges, including the following:

•

the nature, timing and magnitude of financing transactions, which would typically involve issuance of equity or equity-based securities;

•

the nature and timing of product development collaborations, which would typically provide for funding of a portion of the respective product development costs, as well as bring in near-term potential revenues in the form of upfront fees and milestone payments;

•

the breadth of product development programs, i.e., the number of potential disease indications for which a product candidate is tested in clinical trials;

•

the number of products in our development portfolio and the decision to move new product candidates into clinical development; and

•

periodic assessments of the relative capital requirements, risk and value of each of our product candidates.

We expect that it will be several years or more before we can generate enough product-related revenues to reach net income or cash flow breakeven. For example, we currently estimate that in 2007 our net loss will be within the range of approximately $150-170 million, and that we will use net cash of approximately $130-150 million. Revenues from existing relationships help to defray our expenses, but additional funding will be required, the amount of which could be significant. We may decide to enter into additional product development collaborations, which would reduce our funding requirements. We may also generate funding through licensing of patents that are not relevant to our product development programs.

It is likely that we will continue to look for opportunities to raise equity or equity-related capital as a primary means of funding our company over the next several years. These opportunities may arise at any time, depending on things such as overall market conditions; dynamics in the biotechnology sector of the market; investor appetite for certain types of companies; and fundamental characteristics of our business. At other times, it may be difficult to raise capital on terms favorable to our company, if at all. Accordingly, we expect to raise equity capital when it is available, not when there is an immediate need. We believe this strategy is important to minimize the financial risks to our company and our shareholders.

Results of Operations

Revenues

Royalties. We earn royalties on sales of certain products subject to license agreements with Novo Nordisk, our former parent and current owner of approximately 31% of our outstanding common stock, and several other companies. Royalties increased by $98,000 for the three-month period ended March 31, 2007 as compared to the corresponding period in 2006, primarily due to increased platelet-derived growth factor (PDGF) royalties. Insulin and glucagon royalties earned from Novo Nordisk declined to 28% of our total royalties for the three-month period ended March 31, 2007, from 35% for the corresponding period in 2006. This downward trend will continue in 2007 as royalties for both insulin and glucagon in the remaining major markets will end during the second quarter of 2007 due to patent expiration. We anticipate increased royalties on other products to partially offset the decrease in insulin and glucagon royalties.

Option fees. In September 2004, we signed a five-year strategic alliance agreement with Serono S.A. under which Serono may acquire rights and licenses to certain leads and targets from our research and development pipeline. The amount received upfront was deferred and is being recognized over the period in which we have continuing performance obligations. We recorded $784,000 of revenue from this agreement in each of the three-month periods ended March 31, 2007 and 2006. As of March 31, 2007, $7.9 million was recorded as deferred revenue, which is being recognized at a rate of $3.1 million per year.

In the three-month period ended March 31, 2006, we recognized option fee revenue of $1.9 million under an Option and License Agreement with Novo Nordisk, pursuant to which we granted an option to license certain rights to proteins that we discovered. This agreement expired in November 2006, and we recognized no option fee revenue from that agreement following its expiration.

License fees and milestone payments. Revenues from license fees and other up-front payments are recognized over the period we are contractually required to provide other rights or services that represent continuing obligations. For certain license agreements that require no continuing performance of us, we record license fees as revenue upon execution of the agreement and the development-related milestone payments as revenue upon receipt of payment. From period to period, license fees and milestone payments can fluctuate substantially based on the completion of new licensing or collaborative agreements and the achievement of development-related milestones. The decrease of $474,000 in license fees and milestone payments for the three months ended March 31, 2007, as compared to the corresponding period in 2006, resulted from certain amounts earned in the first quarter of 2006 for which no comparable amounts were earned in 2007. Specifically, license fees were earned under an rFactor XIII license agreement with Novo Nordisk for which the license fee revenue recognition period ended in May 2006. Partially offsetting this decrease was the recognition of milestone revenue for IL-20 and the recognition of a license fee for an early stage protein, both from Novo Nordisk, which were earned in the period ended March 31, 2007.

Operating expenses

Research and development. Research and development expense has been our most significant expense to date, consisting primarily of salaries and benefit expenses, costs of consumables, contracted services and stock-based compensation. Our research and development activities have generally been expanding, particularly related to our clinical-stage product candidates, rhThrombin, atacicept, IL-21 and PEG-IFN-l. Research and development expense in both periods was slightly offset by cost reimbursements from Novo Nordisk and Serono for work performed on various development programs. The amounts for the three-month periods ended March 31 are shown in the following table (in thousands):


	2007			2006
Salaries and benefits	$	14,726		$	13,108
Consumables		2,874			2,840
Facility costs		2,116			1,800
Contracted services		5,396			11,062
Depreciation and amortization		1,314			1,377
Stock-based compensation		3,556			2,899

Subtotal		29,982			33,086
Cost reimbursement from collaborators		(214	)		(136	)

Net research and development expense	$	29,768		$	32,950

Salaries and benefits, consumables and facility costs, generally track with increases in our employee base from year to year. Between March 31, 2006 and March 31, 2007, we added approximately 17 full-time equivalent employees who are involved in product development activities.

Contracted services include the cost of items such as contract manufacturing, clinical trials, non-clinical studies and payments to collaborators. These costs relate primarily to clinical development programs and can fluctuate substantially from period-to-period depending on the stage of our various programs. Generally, these external costs increase as a program advances toward commercialization, but there can be periods between major clinical trials or manufacturing campaigns during which costs decline. Our clinical trial costs decreased in the three-month period ended March 31, 2007, as compared to the corresponding period in 2006, primarily reflecting the completion of rhThrombin Phase 3 clinical trials prior to our FDA submission in late 2006. Also, contract manufacturing costs tend to be incurred irregularly over the course of a development program, with relatively short manufacturing campaigns that may provide sufficient product to supply multiple years of clinical trial activity or initial commercial product. Our contract manufacturing costs decreased for the three-month period ended March 31, 2007, as compared to the same period in 2006, reflecting the completion of the process validation and manufacturing campaigns for rhThrombin in 2006 to support the filing of a license application with the FDA in late 2006. We expect to incur significant costs related to the manufacture of rhThrombin bulk drug and finished product inventory over the remainder of 2007. Prior to FDA approval, these costs will be expensed as research and development.

To date, our business needs have not required us to fully allocate all research and development costs among our various programs. However, we track direct labor, contracted services and certain consumable costs by program, which we monitor to ensure appropriate utilization of company resources. We also incur indirect costs that are not allocated to specific programs. These costs include indirect labor, certain consumable costs, facility costs, and depreciation and amortization, all of which benefit all of our research and development programs.

The following table presents our research and development costs allocated to clinical development, pre-development and discovery research programs, together with the unallocated costs that benefit all programs for the three-month periods ended March 31 (in thousands):


	2007		2006
Clinical development programs:
Hemostasis	$	6,676	$	12,203
Autoimmunity and oncology		4,914		4,111
Antiviral		999		1,638
Pre-development programs		1,642		1,008
Discovery research programs		2,984		2,771
Unallocated indirect costs		12,553		11,219

Total	$	29,768	$	32,950

The following summarizes the reasons for significant changes in research and development program costs for the three-month periods presented in the table:

•

Hemostasis clinical development program costs decreased substantially in the 2007 period reflecting reduced rhThrombin manufacturing campaigns and Phase 3 clinical trial costs.

•

Autoimmunity and oncology clinical development program (atacicept and IL-21) costs increased in the 2007 period primarily due to increased efforts and manufacturing costs related to atacicept development in rheumatoid arthritis.

•

Antiviral clinical development program costs declined in the 2007 period. Prior year costs reflecting activities associated with preparing for clinical testing of PEG-IFN-l (e.g. manufacturing and toxicology studies) were higher than the Phase 1 clinical costs in the 2007 period.

•

Pre-development program costs increased in the 2007 period primarily due to a shift of discovery research programs into pre-development.

•

Unallocated indirect costs increased in the 2007 period due to higher personnel, consulting and facilities costs.

General and administrative. General and administrative expense, which consists primarily of salaries and benefit expenses, professional fees and other corporate costs, increased 24% for the three-month period ended March 31, 2007, as compared to the corresponding period in 2006. The increase was primarily due to increased personnel, legal and marketing costs.

Stock-based compensation. Stock-based compensation expense increased 21% for the three-month period ended March 31, 2007, as compared to the corresponding period in 2006. The increase was primarily due to a greater number of stock options awarded as a result of an increase in personnel. The following amounts of stock-based compensation expense were recorded for the three-month periods ended March 31 (in thousands):


	2007		2006
Research and development expense	$	3,556	$	2,899
General and administrative expense		1,895		1,619

Total	$	5,451	$	4,518

Other income (expense)

Investment income. Investment income is generated primarily from investment of our cash reserves in investment grade, fixed-income securities. There are three primary factors affecting the amount of investment income that we report: the amount of cash reserves invested, the effective interest rate, and the amount of gains or losses recognized. The following table shows how each of these factors affected investment income for the three-month periods ended March 31 (in thousands):


	2007			2006
Weighted average amount of cash reserves	$	235,874		$	346,271
Effective quarterly interest rate		1.23	%		1.05	%

Interest earned		2,910			3,629
Net realized losses on short-term investments		(32	)		(1	)

Investment income, as reported	$	2,878		$	3,628

Interest expense. We have accounted for a sale-leaseback transaction completed in October 2002 as a financing transaction. Under this method of accounting, an amount equal to the net proceeds of the sale is considered a long-term interest bearing liability. Rent payments under the leases are considered to be payments toward the liability and are allocated to principal and interest. Interest expense was relatively constant for the three-month periods ended March 31, 2007 and 2006.

Liquidity and Capital Resources

As of March 31, 2007, we had cash, cash equivalents and short-term investments of $224.0 million, which we intend to use to fund our operations and capital expenditures until we are able to generate positive cash flow. These cash reserves are held in a variety of investment-grade, fixed-income securities, including corporate bonds, commercial paper and money market instruments. We believe that our existing cash resources should provide sufficient funding through 2008. We plan to complete additional collaborative development transactions, which would generate both revenues and cost reductions, potentially enabling these cash resources to fund our company over a longer period of time.

Cash flows from operating activities. The amount of cash used to fund our operating activities generally tracks our net losses, with the following exceptions:

•

noncash expenses, such as depreciation and amortization, gain or loss on sale or disposal of assets, and stock-based compensation, which do not result in uses of cash;

•

net realized gains and losses and accretion and amortization of discounts and premiums on short-term investments, which are reflected as sources of cash from investing activities upon maturity or sale of the respective investments;

•

changes in receivables, which generally represent temporary timing differences between the recognition of certain revenues and the subsequent receipt of cash payments;

•

changes in deferred revenue, which reflect the difference in timing between the receipt of cash from option fees, license fees and other upfront payments and the subsequent recognition of these amounts as revenue over the period we are contractually required to provide other rights or services that represent continuing obligations; and

•

changes in other assets and liabilities, which generally represent temporary timing differences between the recognition of certain expenses and their payment.

Generally, with the exception of changes in deferred revenue, we do not expect these items to generate material year-to-year fluctuations in the relationship between our net loss and the amount of net cash used in operating activities. Substantial license or upfront fees may be received upon the date we enter into new licensing or collaborative agreements and be recorded as deferred revenue. For example, in 2004 upon the execution of a strategic alliance agreement with Serono, we recorded $24.3 million of deferred revenue, which is being recognized as revenue over approximately five years. For the three-month periods ended March 31, 2007 and 2006, we recognized $1.5 million and $5.6 million, respectively, of previously deferred revenue from this and other transactions. The timing of additional deferred revenue transactions is expected to be irregular and, thus, has the potential to create fluctuations in the relationship between our net loss and the amount of cash used in operating activities.

Cash flows from investing activities. Our most significant use of cash in investing activities is for capital expenditures. We expend a certain amount each year on routine items to maintain the effectiveness of our business, e.g., to adopt newly developed technologies, expand into new functional areas, adapt our facilities to changing needs and/or replace obsolete assets. In addition, we have used cash at various times to purchase land and expand facilities. Cash flows from investing activities also reflect large amounts of cash used to purchase short-term investments and receipts from the sale and maturity of short-term investments. These amounts primarily relate to shifts between cash and cash equivalents and short-term investments. Because we manage our cash usage with respect to our total cash, cash equivalents and short-term investments, we do not consider these cash flows to be important to an understanding of our liquidity and capital resources.

Cash flows from financing activities. We received $2.4 million and $4.0 million of proceeds from the exercise of stock options for the three-month periods ended March 31, 2007 and 2006, respectively.

We expect to incur substantial additional costs as we continue to advance and expand our product development programs. We expect these expenditures to increase over the next several years, particularly if the outcomes of clinical trials are successful and our product candidates continue to advance. Our plans include the internal development of selected product candidates and the co-development of product candidates with collaborators where we would assume a percentage of the overall product development costs. We also expect to incur substantial amounts during 2007 supporting the planned launch of rhThrombin in the fourth quarter of 2007. Although we are optimistic regarding its commercial prospects and the rate of market penetration, it might be quite some time, if ever, before our rhThrombin revenues exceed our expenses. If at any time our prospects for financing these various initiatives decline, we may decide to look for ways to reduce our ongoing investment. In such event, we might consider discontinuing our funding under existing co-development arrangements, establishing new co-development arrangements for other product candidates to provide additional funding sources or out-licensing rhThrombin or other product candidates that we might otherwise develop and commercialize internally. Additionally, we could consider delaying or discontinuing development of product candidates to reduce the level of our related expenditures.

Our long-term capital requirements and the adequacy of our available funds will depend on several factors, many of which may not be in our control, including:

•

success in gaining approval of and subsequently marketing and selling rhThrombin;

•

results of research and development programs;

•

cash flows under existing and potential future arrangements with licensees, collaborators and other parties;

•

costs involved in filing, prosecuting, enforcing and defending patent claims; and

•

costs associated with the expansion of our facilities.

Over the next several years we expect to seek additional funding through public or private financings, including equity financings, and through other arrangements, including collaborative arrangements. Poor financial results, unanticipated expenses or unanticipated opportunities that require financial commitments could give rise to additional financing requirements sooner than we expect. However, financing may be

unavailable when we need it or may not be available on acceptable terms. If we raise additional funds by issuing equity or equity-based securities, the percentage ownership of our existing shareholders would be reduced, and these securities could have rights superior to those of our common stock. If we are unable to raise additional funds when we need them, we could be required to delay, scale back or eliminate expenditures for some of our development programs or expansion plans, or grant rights to third parties to develop and market product candidates that we would prefer to develop and market internally, with license terms that are not favorable to us.

Contractual Obligations

At March 31, 2007, we were contractually obligated to make payments as follows (in thousands):


	Payments Due by Period
	Total		Less than 1 Year		1-3 Years		3-5 Years		More than 5 Years
Building lease obligations	$	113,843	$	7,676	$	16,168	$	17,319	$	72,680
Operating leases		9,990		2,452		4,259		3,279		—
Development contracts		22,114		22,114		—		—		—

Total	$	145,947	$	32,242	$	20,427	$	20,598	$	72,680

The building lease obligations resulted from our 2002 sale-leaseback financing transaction and run until May 2019. The remaining terms of our operating leases range from approximately two to five years and generally relate to leased office space nearby our corporate headquarter buildings. We have certain renewal provisions at our option, which are not reflected in the above table, for the building leases and the operating leases. The development contracts largely reflect the manufacture of rhThrombin bulk drug and finished product for eventual commercial sale.

Item 3.

Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk is primarily limited to interest income sensitivity, which is affected by changes in the general level of United States interest rates, particularly because the majority of our investments are in short-term debt securities. The primary objective of our investment activities is to preserve principal while at the same time maximizing the income we receive without significantly increasing risk. To minimize risk, we maintain our portfolio of cash, cash equivalents and short-term investments in a variety of interest-bearing instruments, which may include United States government and agency securities, high-grade United States corporate bonds, asset-backed securities, commercial paper and money market funds. Due to the nature of our short-term investments, all of which mature within three years, we believe that we are not subject to any material market risk exposure. We have no material foreign currency exposure, nor do we hold derivative financial instruments.

Item 4.

Controls and Procedures

Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of the end of the period covered by this report, have concluded that as of such date our disclosure controls and procedures were effective. No change in our internal control over financial reporting occurred during the quarter ended March 31, 2007 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
