	Summary of Significant Accounting Policies

	Basis of Presentation

	The accompanying interim condensed consolidated financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“GAAP”) and with the instructions for Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on April 2, 2014. The unaudited condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.

	Principles of Consolidation

	The Company has interests in joint venture entities that are variable interest entities (“VIEs”). Determining whether to consolidate a variable interest entity requires judgment in assessing (i) whether an entity is a VIE and (ii) if the Company is the entity’s primary beneficiary and thus required to consolidate the entity. To determine if the Company is the primary beneficiary of a VIE, the Company evaluates whether it has (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company’s evaluation includes identification of significant activities and an assessment of its ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding and financing and other applicable agreements and circumstances. The Company’s assessment of whether it is the primary beneficiary of its VIEs requires significant assumptions and judgment.

	The condensed consolidated financial statements of the Company include the accounts of Amyris, Inc., its subsidiaries and two consolidated VIEs with respect to which the Company is considered the primary beneficiary, after elimination of intercompany accounts and transactions. Disclosure regarding the Company’s participation in the VIEs is included in Note 7, "Joint Venture and Noncontrolling Interest."

	Use of Estimates

	In preparing the unaudited condensed consolidated financial statements, management must make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

	Unaudited Interim Financial Information

	The accompanying interim condensed consolidated financial statements and related disclosures are unaudited, have been prepared on the same basis as the annual consolidated financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for a fair statement of the results of operations for the periods presented.
	The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. The condensed consolidated results of operations for any interim period are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period.

	Recent Accounting Pronouncements

	In July 2013, the Financial Accounting Standards Board ("FASB") issued an amended accounting standard update on the financial statement presentation of unrecognized tax benefits. The amended guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance became effective for the Company on January 1, 2014 and will be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective applications permitted. The Company's current presentation of unrecognized tax benefits conforms with the amended guidance. Accordingly, there was no significant impact to the Company resulting from the guidance.

	The Company

	Amyris, Inc. (the “Company”) was incorporated in California on July 17, 2003 and reincorporated in Delaware on June 10, 2010 for the purpose of leveraging breakthroughs in synthetic biology to develop and provide renewable compounds for a variety of markets. The Company is currently applying its industrial synthetic biology platform to provide alternatives to select petroleum-sourced products used in consumer care, specialty chemical and transportation fuel markets worldwide. The Company's first commercialization efforts have been focused on a renewable hydrocarbon molecule called farnesene (Biofene®), which forms the basis for a wide range of products including emollients, fragrance oils and diesel fuel. While the Company's platform is able to use a wide variety of feedstocks, the Company is initially focused on Brazilian sugarcane. In addition, the Company has entered into various contract manufacturing agreements to support commercial production. The Company has established two principal operating subsidiaries, Amyris Brasil Ltda. (formerly "Amyris Brasil S.A.", or "Amyris Brasil") for production in Brazil, and Amyris Fuels, LLC (or "Amyris Fuels").

	The Company's renewable products business strategy is to focus on direct commercialization of specialty products while moving established commodity products into joint venture arrangements with leading industry partners. To commercialize its products, the Company must be successful in using its technology to manufacture its products at commercial scale and on an economically viable basis (i.e., low per unit production costs). The Company is building its experience producing renewable products at commercial scale. The Company's prospects are subject to risks, expenses and uncertainties frequently encountered by companies in this stage of development.

	The Company expects to fund its operations for the foreseeable future with cash and investments currently on hand, with cash inflows from collaboration and grant funding, cash contributions from product sales, and with new debt and equity financings. The Company's planned 2014 and 2015 working capital needs and its planned operating and capital expenditures are dependent on significant inflows of cash from new and existing collaboration partners and from cash contributions from growth in renewable product sales, as well as additional funding from new joint ventures or other collaborations, and may also require additional funding from debt or equity financings. The Company will continue to need to fund its research and development and related activities and to provide working capital to fund production, storage, distribution and other aspects of its business. The Company's operating plan contemplates capital expenditures of approximately $9.0 million in 2014 and the Company expects to continue to incur costs in connection with its existing contract manufacturing arrangements.

	Liquidity

	The Company has incurred significant losses since its inception and believes that it will continue to incur losses and negative cash flow from operations through 2014. As of March 31, 2014, the Company had an accumulated deficit of $805.1 million and had cash, cash equivalents and short term investments of $49.1 million. The Company has significant outstanding debt and contractual obligations related to purchase commitments, as well as capital and operating leases. As of March 31, 2014, the Company's debt, net of discount of $54.6 million, totaled $178.6 million, of which $6.8 million matures within the next twelve months. In addition, the Company's debt agreements contain various covenants, including restrictions on the Company's business that could cause the Company to be at risk of defaults. Please refer to Note 5, “Debt” and Note 6, “Commitments and Contingencies” for further details regarding the Company's obligations and commitments.

	The Company’s operating plan for 2014 contemplates significant reduction in the Company’s net cash outflows, resulting from (i) revenue growth from sales of existing and new products, (ii) reduced production costs compared to prior periods as a result of manufacturing and technical developments in 2013, (iii) cash inflows from collaborations consistent with levels achieved in 2013 and (iv) operating expenses maintained at reduced levels. Achieving a reduction in net cash outflows from these factors is subject to risks and uncertainties, including those set forth in Part II, Item 1A of this Quarterly Report on Form 10-Q, “Risk Factors.”

	In addition to cash contributions from product sales and debt and equity financings, the Company also depends on collaboration funding to support its operating expenses. While part of this funding is committed based on existing collaboration agreements, the Company will need to identify and obtain funding under additional collaborations that are not yet subject to any definitive agreement or are not yet identified. In addition, some of the Company’s existing collaboration funding is subject to achievement by the Company of milestones or other funding conditions.

	If the Company cannot secure sufficient collaboration funding to support its operating expenses in excess of cash contributions from product sales and existing debt and equity financings, it may need to issue additional preferred and/or discounted equity, agree to onerous covenants, grant further security interest in its assets, enter into collaboration and licensing arrangements that require it to relinquish commercial rights, or grant licenses on terms that are not favorable. If the Company fails to secure such funding, the Company could be forced to curtail its operations, which would have a material adverse effect on the Company's ability to continue with its business plans, and the Company's status as a going concern.

	If the Company is unable to raise additional financing, or if other expected sources of funding are delayed or not received, the Company would be required to take any of the following actions by the end of the second quarter of 2014 to support its liquidity needs through the remainder of 2014 and into 2015:


	•	Effect significant headcount reductions in the United States and Brazil, particularly with respect to both general and administrative employees and other employees not connected to critical or contracted activities.


	•	Shift its focus to existing products and customers with significantly reduced investment in new product and commercial development efforts.


	•	Reduce its expenditures for third party contractors, including consultants, professional advisors and other vendors.


	•	Suspend operations at its pilot plants and demonstration facilities.


	•	Reduce or delay uncommitted capital expenditures, including non-essential laboratory equipment and information technology projects.

	The contingency cash plan contemplating these actions is designed to save the Company an estimated $25.0 million to $35.0 million over the next twelve months. Implementing this plan could have a material negative impact on the Company's ability to continue its business as currently contemplated, including, without limitation, delays or failures in its ability to:


	•	Achieve planned production levels.


	•	Develop and commercialize products within planned timelines or at planned scales.


	•	Continue other core activities.

	Furthermore, any inability to scale-back operations as necessary, and any unexpected liquidity needs, could create pressure to implement more severe measures. Such measures could have a material adverse effect on the Company's ability to meet contractual requirements, including obligations to maintain manufacturing operations, and increase the severity of the consequences described above.

	Fair Value of Financial Instruments

	The inputs to the valuation techniques used to measure fair value are classified into the following categories:

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

	Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

	Level 3: Unobservable inputs that are not corroborated by market data.

	As of March 31, 2014, the Company’s financial assets and financial liabilities are presented below at fair value and were classified within the fair value hierarchy as follows (in thousands):


		Level 1				Level 2				Level 3				Balance as of March 31, 2014

	Total financial liabilities	$	—			$	55,140			$	290,034			$	345,174


	(1) These liabilities are carried on the condensed consolidated balance sheet on a historical basis.

	The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires management to make judgments and consider factors specific to the asset or liability. The fair values of money market funds are based on fair values of identical assets. The fair values of the loans payable, convertible notes, credit facilities and currency interest rate swaps are based on the present value of expected future cash flows and assumptions about current interest rates and the creditworthiness of the Company. Market risk associated with the fixed and variable rate long-term debt relates to the potential reduction in fair value and negative impact to future earnings, respectively, from an increase in interest rates.

	The carrying amounts of certain financial instruments, such as cash equivalents, short term investments, accounts receivable, accounts payable and accrued liabilities, approximate fair value due to their relatively short maturities and low market interest rates, if applicable. The fair values of the loans payable, convertible notes and credit facilities are based on the present value of expected future cash flows and assumptions about current interest rates and the creditworthiness of the Company.

	The following table provides a reconciliation of the beginning and ending balances for the convertible notes measured at fair value using significant unobservable inputs (Level 3) (in thousands):

______________
(1) Includes $1.1 million removal of derivative liability related to debt extinguishment.

The compound embedded derivative liability represents the fair value of the bifurcated conversion options that contain "make-whole" provisions or down round conversion price adjustment provisions of outstanding convertible promissory notes issued to Total Energies Nouvelles Activités USA (formerly known as Total Gas & Power USA, SAS, or “Total”) , as well as Tranche I Notes and Tranche II Notes (see Note 5, "Debt"). There is no current observable market for this type of derivative and, as such, the Company determined the fair value of the embedded derivative using a Monte Carlo simulation valuation model for the Total Notes and the binomial lattice model for the Tranche I Notes and Tranche II Notes. A Monte Carlo simulation valuation model combines expected cash outflows with market-based assumptions regarding risk-adjusted yields, stock price volatility, probability of a change of control and the trading information of the Company's common stock into which the notes are convertible. A binomial lattice model generates two probable outcomes - one up and another down - arising at each point in time, starting from the date of valuation until the maturity date. A lattice model was initially used to determine if the convertible notes would be converted, called or held at each decision point. Within the lattice model, the following assumptions are made: (i) the convertible notes will be converted early if the conversion value is greater than the holding value or (ii) the convertible notes will be called if the holding value is greater than both (a) redemption price and (b) the conversion value at the time. If the convertible notes are called, then the holder will maximize their value by finding the optimal decision between (1) redeeming at the redemption price and (2) converting the convertible notes. Using this lattice method, the Company valued the embedded derivative using the "with-and-without method", where the fair value of the convertible notes including the embedded derivative is defined as the "with", and the fair value of the convertible notes excluding the embedded derivative is defined as the "without". This method estimates the fair value of the embedded derivative by looking at the difference in the values between the convertible notes with the embedded derivative and the fair value of the convertible notes without the embedded derivative. The lattice model uses the stock price, conversion price, maturity date, risk-free interest rate, estimated stock volatility and estimated credit spread. The Company marks the compound embedded derivative to market due to the conversion price not being indexed to the Company's own stock. Except for the "make-whole interest" provision included in the conversion option, which is only required to be settled in cash upon a change of control at the noteholder's option, the compound embedded derivative will be settled in either cash or shares. As of March 31, 2014, the Company has sufficient common stock available to settle the conversion option in shares. As of March 31, 2014 and December 31, 2013, included in Derivative Liability on the condensed consolidated balance sheet is the Company's compound embedded derivative liability of $111.4 million and 131.1 million, respectively, which represents the fair value of the equity conversion option or a "make-whole" provision relating to the outstanding senior secured convertible promissory notes issued to Total, Tranche I Notes and Tranche II Notes as described above.

In June 2012, the Company entered into a loan agreement with Banco Pine S.A. (or "Banco Pine") under which Banco Pine provided the Company with a short term loan (referred to as the "Banco Pine Bridge Loan") (see Note 5, "Debt"). At the time of the Banco Pine Bridge Loan, the Company also entered into a currency interest rate swap arrangement with Banco Pine with respect to the repayment of R$22.0 million (approximately US$9.7 million based on the exchange rate as of March 31, 2014). The swap arrangement exchanges the principal and interest payments under the Banco Pine Bridge Loan of R$22.0 million entered into in July 2012 for alternative principal and interest payments that are subject to adjustment based on fluctuations in the foreign exchange rate between the U.S. dollar and Brazilian real. The swap has a fixed interest rate of 3.94%. Changes in the fair value of the swap are recognized in “Income from change in fair value of derivative instruments" in the condensed consolidated statements of operations.

	FINEP Credit Facility

	In November 2010, the Company entered into a credit facility with Financiadora de Estudos e Projetos (referred to as the “FINEP Credit Facility”). This FINEP Credit Facility was extended to partially fund expenses related to the Company’s research and development project on sugarcane-based biodiesel (“FINEP Project”) and provided for loans of up to an aggregate principal amount of R$6.4 million (approximately US$2.8 million based on the exchange rate as of March 31, 2014), which is secured by a chattel mortgage on certain equipment of the Company as well as by bank letters of guarantee. All available credit under this facility is fully drawn.

	Interest on loans drawn under the FINEP Credit Facility is fixed at 5% per annum. In case of default under or non-compliance with the terms of the agreement, the interest on loans will be dependent on the long-term interest rate as published by the Central Bank of Brazil (such rate, the “TJLP”). If the TJLP at the time of default is greater than 6%, then the interest will be 5% plus a TJLP adjustment factor, otherwise the interest will be at 11% per annum. In addition, a fine of up to 10% shall apply to the amount of any obligation in default. Interest on late balances will be 1% interest per month, levied on the overdue amount. Payment of the outstanding loan balance is being made in 81 monthly installments, which commenced in July 2012 and extends through March 2019. Interest on loans drawn and other charges are paid on a monthly basis and commenced in March 2011. As of March 31, 2014 and December 31, 2013, the total outstanding loan balance under this credit facility was R$5.0 million (approximately US$2.2 million based on the exchange rate as of March 31, 2014) and R$5.2 million (approximately US$2.2 million based on exchange rate as of December 31, 2013), respectively.

	The FINEP Credit Facility contains the following significant terms and conditions:

	•	the Company was required to share with FINEP the costs associated with the FINEP Project. At a minimum, the Company was required to contribute from its own funds approximately R$14.5 million (approximately US$6.4 million based on the exchange rate as of March 31, 2014) of which R$11.1 million was contributed prior to the release of the second disbursement. All four disbursements were completed and the Company has fulfilled all of its cost sharing obligations;

	•	after the release of the first disbursement, prior to any subsequent drawdown from the FINEP Credit Facility, the Company was required to provide bank letters of guarantee of up to R$3.3 million in aggregate (approximately US$1.5 million based on the exchange rate as of March 31, 2014). On December 17, 2012 and prior to release of the second disbursement on December 26, 2012, the Company obtained the required bank letter of guarantees from Banco ABC Brasil S.A. (or "ABC"); and

	•	amounts disbursed under the FINEP Credit Facility were required to be used towards the FINEP Project within 30 months after the contract execution.


	BNDES Credit Facility

	In December 2011, the Company entered into a credit facility with the Brazilian Development Bank (the bank is referred to as “BNDES” and the credit facility referred to as the “BNDES Credit Facility”) in the amount of R$22.4 million (approximately US$9.9 million based on the exchange rate as of March 31, 2014). This BNDES Credit Facility was extended as project financing for a production site in Brazil. The credit line is divided into an initial tranche of up to approximately R$19.1 million and an additional tranche of approximately R$3.3 million that becomes available upon delivery of additional guarantees. The credit line is available for 12 months from the date of the BNDES Credit Facility, subject to extension by the lender. The credit line was cancelled in 2013.
	The principal of the loans under the BNDES Credit Facility is required to be repaid in 60 monthly installments, with the first installment paid in January 2013 and the last due in December 2017. Interest was due initially on a quarterly basis with the first installment due in March 2012. From and after January 2013, interest payments are due on a monthly basis together with principal payments. The loaned amounts carry interest of 7% per annum. Additionally, there is a credit reserve charge of 0.1% on the unused balance from each credit installment from the day immediately after it is made available through its date of use, when it is paid.

	The BNDES Credit Facility is collateralized by a first priority security interest in certain of the Company's equipment and other tangible assets totaling R$24.9 million (approximately US$11.0 million based on the exchange rate as of March 31, 2014). The Company is a parent guarantor for the payment of the outstanding balance under the BNDES Credit Facility. Additionally, the Company was required to provide a bank guarantee equal to 10% of the total approved amount (R$22.4 million in total debt) available under this Credit Facility. For advances of the second tranche (above R$19.1 million), the Company is required to provide additional bank guarantees equal to 90% of each such advance, plus additional Company guarantees equal to at least 130% of such advance. The BNDES Credit Facility contains customary events of default, including payment failures, failure to satisfy other obligations under this credit facility or related documents, defaults in respect of other indebtedness, bankruptcy, insolvency and inability to pay debts when due, material judgments, and changes in control of Amyris Brasil. If any event of default occurs, the Lender may terminate its commitments and declare immediately due all borrowings under the facility. As of March 31, 2014 and December 31, 2013, the Company had R$14.3 million (approximately US$6.1 million based on the exchange rate as of March 31, 2014) and R$15.3 million (approximately US$6.5 million based on the exchange rate as of December 31, 2013), respectively, in outstanding advances under the BNDES Credit Facility.

	Hercules Loan Facility

	In March 2014, the Company entered into a loan and security agreement with Hercules Technology Growth Capital, Inc. (referred to as “Hercules”) to make available to Amyris a loan in the aggregate principal amount of up to $25.0 million (referred to as the "Hercules Loan Facility"). The Hercules Loan Facility generally becomes due on May 31, 2015 and accrues interest at a rate per annum equal to the greater of either the prime rate reported in the Wall Street Journal plus 6.25% or 9.5%. The maturity date is extended to February 1, 2017 if the Company completes a financing transaction for at least $50.0 million in additional cash proceeds by September 30, 2014. The Company may repay the loaned amounts before the maturity date if it pays an additional fee of 3% of the outstanding loans (1% if after the initial twelve-month period). The Company is also required to pay a 1% facility charge at the closing of the transaction, and a 10% end of term charge. In connection with the Hercules Loan Facility, Amyris agreed to certain customary representations and warranties and covenants, as well as certain covenants with respect to obtaining additional financing as described above and filing with the SEC an effective Registration on Form S-3 by no later than June 30, 2014 and certain performance covenants related to revenues and cash flows starting with the third quarter of 2014. If the Company does not complete a financing transaction for at least $50.0 million in additional cash proceeds by September 30, 2014, a forbearance fee of $10.0 million becomes due and is required to be paid on May 31, 2015. As of March 31, 2014 the total available amount of $25.0 million was fully drawn down by the Company.

	Notes Payable

	During the period between May 2008 and October 2008, the Company entered into notes payable agreements with the lessor of its headquarters under which it borrowed a total of $3.3 million for the purchase of tenant improvements, bearing an interest rate of 9.5% per annum and to be repaid over a period of 55 to 120 months. As of March 31, 2014 and December 31, 2013, no principal amount was outstanding under these notes payable. In June 2013, as part of the April 30, 2013 Amendment to the Company's operating lease for its headquarters, the Company recorded the elimination of these notes payable as a lease incentive and recorded approximately $1.4 million to deferred rent liability in the condensed consolidated balance sheet. The deferred rent liability is being amortized to expense over the remaining lease term.


	Convertible Notes

	In February 2012, the Company completed the sale of senior unsecured convertible promissory notes in an aggregate principal amount of $25.0 million pursuant to a securities purchase agreement, between the Company and certain investment funds affiliated with FMR LLC (referred to as the "Fidelity Securities Purchase Agreement"). The offering consisted of the sale of 3% senior unsecured convertible promissory notes with a March 1, 2017 maturity date and an initial conversion price equal to $7.0682 per share of the Company's common stock, subject to proportional adjustment for adjustments to outstanding common stock and anti-dilution provisions in case of dividends and distributions (referred to as the "Fidelity Notes"). As of March 31, 2014, the Fidelity Notes were convertible into an aggregate of up to 3,536,968 shares of the Company's common stock. Such note holders have a right to require repayment of 101% of the principal amount of the Fidelity Notes in an acquisition of the Company, and the notes provide for payment of unpaid interest on conversion following such an acquisition if the note holders do not require such repayment. The Fidelity Securities Purchase Agreement and Fidelity Notes include covenants regarding payment of interest, maintaining the Company's listing status, limitations on debt, maintenance of corporate existence, and filing of SEC reports. The Fidelity Notes include standard events of default resulting in acceleration of indebtedness, including failure to pay, bankruptcy and insolvency, cross-defaults, material adverse effect clauses and breaches of the covenants in the Fidelity Securities Purchase Agreement and Fidelity Notes, with default interest rates and associated cure periods applicable to the covenant regarding SEC reporting. Furthermore, the Fidelity Notes include restrictions on the amount of debt the Company is permitted to incur. With exceptions for certain existing debt, refinancing of such debt and certain other exclusions and waivers, the Fidelity Notes provide that the Company's total outstanding debt at any time cannot exceed the greater of $200.0 million or 50% of its consolidated total assets and its secured debt cannot exceed the greater of $125.0 million or 30% of its consolidated total assets. In connection with the Company’s closing of a short-term bridge loan for $35.0 million in October 2013, holders of the Fidelity Notes waived compliance with the debt limitations outlined above as to the $35.0 million bridge loan and the August 2013 Financing (defined below). In consideration for such waiver, the Company granted to holders of the Fidelity Notes or their affiliates, the right to purchase up to an aggregate of $7.6 million worth of convertible promissory notes in the first tranche of the August 2013 Financing.

	In August 2013, the Company entered into that certain Securities Purchase Agreement, dated as of August 8, 2013 (referred to as the “August 2013 SPA”), for the sale of senior convertible promissory notes (referred to as the “August 2013 Notes”) to Maxwell (Mauritius) Pte Ltd (or “Temasek”) and Total, each of whom are existing stockholders of the Company. The August 2013 SPA contemplated the sale of up to an aggregate of $73.0 million in principal amount of the August 2013 Notes in a private placement (referred to as the “August 2013 Financing”) exempt from registration under the Securities Act of 1933, as amended, in an initial tranche of $42.6 million in aggregate principal amount and a second tranche of $30.4 million in aggregate principal amount.

	In October 2013, the Company amended the August 2013 SPA to include certain entities affiliated with FMR LLC (referred to as the “Fidelity Entities”) in the first tranche of the August 2013 Financing. Pursuant to the amended agreement the Company sold senior convertible notes with an aggregate principal amount of $7.6 million to the Fidelity Entities (referred to as the "Tranche I Notes"). The Tranche I Notes are due sixty months from the date of issuance and will be convertible into the Company’s common stock at a conversion price equal to $2.44, which represents a 15% discount to a trailing 60-day weighted-average closing price of the common stock on The NASDAQ Stock Market (or “NASDAQ”) through August 7, 2013, subject to adjustment as described below. The Tranche I Notes are convertible at the option of the holder: (i) at any time after 18 months from the date of the August 2013 SPA, (ii) on a change of control of the Company and (iii) upon the occurrence of an event of default. The conversion price of the Tranche I Notes will be reduced to $2.15 if either (a) a specified Company manufacturing plant fails to achieve a total production of 1,000,000 liters within a run period of 45 days prior to June 30, 2014, or the Company fails to achieve gross margins from product sales of at least 5% prior to June 30, 2014, or (b) the Company reduces the conversion price of certain existing promissory notes held by Total prior to the repayment or conversion of the Tranche I Notes; provided, however, that, if both of the conditions described in clauses (a) and (b) occur, the conversion price of the Tranche I Notes shall be reduced to $1.87. Each Tranche I Note accrues interest from the date of issuance until the earlier of the date that such Tranche I Note is converted into the Company’s common stock or is repaid in full. Interest accrues at a rate of 5% per six months, compounded semiannually (with graduated interest rates of 6.5% applicable to the first 180 days and 8% applicable thereafter as the sole remedy should the Company fail to maintain NASDAQ listing status or at 6.5% for all other defaults). Interest for the first 30 months is payable in kind and added to the principal every six-months and thereafter, the Company may continue to pay interest in kind by adding to the principal every six-months or may elect to pay interest in cash. The Tranche I Notes may be prepaid by the Company after 30 months from the issuance date and initial interest payment date; thereafter the Company has the option to prepay the Tranche I Notes every six months at the date of payment of the semi-annual coupon.

	As of March 31, 2014 and December 31, 2013, principal amount of $28.7 million and $28.6 million, respectively, were outstanding under these convertible notes, net of debt discount of $3.8 million and $4.0 million, respectively.

Related Party Convertible Notes
Total R&D Convertible Notes

In July 2012, the Company entered into an agreement with Total that expanded Total's investment in the Biofene collaboration with the Company, provided new structure for a joint venture (referred to as the "Fuels JV") to commercialize the products encompassed by the diesel and jet fuel research and development program (or, the "Program"), and established a convertible debt structure for the collaboration funding from Total (referred to as the "July 2012 Agreements").

The purchase agreement for the notes related to the funding from Total (referred to as the "Total Purchase Agreement") provides for the sale of an aggregate of $105.0 million in notes as follows:


•	As part of an initial closing under the purchase agreement (which initial closing was completed in two installments), (i) on July 30, 2012, the Company sold a 1.5% Senior Unsecured Convertible Note due March 2017 to Total in the face amount of $38.3 million, including $15.0 million in new funds and $23.3 million in previously-provided diesel research and development funding by Total, and (ii) on September 14, 2012, the Company sold another note (in the same form) for $15.0 million in new funds from Total.

•	At a second closing under the Total Purchase Agreement (also completed in two installments) the Company sold additional notes for an aggregate of $30.0 million in new funds from Total ($10.0 million in June 2013 and $20.0 million in July 2013).

•	The Total Purchase Agreement provides that additional notes may be sold in subsequent closings in July 2014 (for cash proceeds to the Company of $21.7 million, which would be settled in an initial installment of $10.85 million payable at such closing and a second installment of $10.85 million payable in January 2015).

The notes issued to Total have a maturity date of March 1, 2017, an initial conversion price equal to $7.0682 per share for the notes issued under the initial closing and an initial conversion price equal $3.08 per share for the notes issued under the second closing. The notes to be issued to Total in the third closing described above will have an initial conversion price equal to $4.11 subject to stockholder approval of an amendment to the conversion price of such notes at the Company’s 2014 annual meeting, which amendment reduced the conversion price of the notes to be issued in the third closing from $7.0682 to $4.11, subject to stockholder approval. The notes bear interest of 1.5% per annum (with a default rate of 2.5%), accruing from the date of funding and payable at maturity or on conversion or a change of control where Total exercises the right to require the Company to repay the notes. Accrued interest is cancelled if the notes are cancelled based on a “Go” decision (see Note 8, "Significant Agreements"). The agreements contemplate that the research and development efforts under the Program may extend through 2016, with a series of “Go/No Go” decisions (see Note 8, "Significant Agreements") by Total through such date tied to funding by Total. The notes issuable under the third closing will be senior secured promissory notes, pursuant to the exchange agreed to by Total and the Company in December 2013.

The notes become convertible into the Company's common stock (i) within 10 trading days prior to maturity (if they are not cancelled as described above prior to their maturity date), (ii) on a change of control of the Company, (iii) if Total is no longer the largest stockholder of the Company following a “No-Go” decision (subject to a six-month lock-up with respect to any shares of common stock issued upon conversion), and (iv) on a default by the Company. If Total makes a final “Go” decision, then the notes will be exchanged by Total for equity interests in the Fuels JV, after which the notes will not be convertible and any obligation to pay principal or interest on the notes will be extinguished. If Total makes a “No-Go” decision, outstanding notes will remain outstanding and become payable at maturity.

In connection with a December 2012 private placement of the Company’s common stock involving certain existing stockholders of the Company (see Note 10, "Stockholders Deficit", Total elected to participate in the private placement by exchanging approximately $5.0 million of its $53.3 million in senior unsecured convertible promissory notes into 1,677,852 of the Company's common stock at $2.98 per share. As such, $5.0 million of Total's outstanding $53.3 million in senior unsecured convertible promissory notes was cancelled. The cancellation of the debt was treated as an extinguishment of debt in accordance with the guidance outlined in ASC 470-50. As a result of the exchange and cancellation of the $5.0 million debt the Company recorded a loss from extinguishment of debt of $0.9 million.

In March 2013, the Company entered into a letter agreement with Total (referred to as the "March 2013 Letter Agreement") under which Total agreed to waive its right to cease its participation in the parties' fuels collaboration at the July 2013 decision point and committed to proceed with the July 2013 funding tranche of $30.0 million (subject to the Company's satisfaction of the relevant closing conditions for such funding in the Total Purchase Agreement). As consideration for this waiver and commitment, the Company agreed to:


•	reduce the conversion price for the senior unsecured convertible promissory notes to be issued in connection with such funding from $7.0682 per share to a price per share equal to the greater of (i) the consolidated closing bid price of the Company's common stock on the date of the March 2013 Letter Agreement, plus $0.01, and (ii) $3.08 per share, provided that the conversion price would not be reduced by more than the maximum possible amount permitted under the rules of NASDAQ such that the new conversion price would require the Company to obtain stockholder consent; and

•	grant Total a senior security interest in the Company's intellectual property, subject to certain exclusions and subject to release by Total when the Company and Total enter into final documentation regarding the establishment of the Fuels JV.

In addition to the waiver by Total described above, Total also agreed that, at the Company's request and contingent upon the Company meeting its obligations described above, it would pay advance installments of the amounts otherwise payable at the July 2013 closing. Specifically, if the Company requested such advance installments, subject to certain closing conditions and delivery of certifications regarding the Company's cash levels, Total was obligated to fund $10.0 million no later than May 15, 2013, and an additional $10.0 million no later than June 15, 2013, with the remainder to be funded on the original July 2013 closing date.

In June 2013, the Company sold and issued a 1.5% Senior Unsecured Convertible Note to Total in the face amount of $10.0 million with a March 1, 2017 maturity date pursuant to the Total Purchase Agreement as discussed above. In accordance with the March 2013 Letter Agreement, this convertible note has an initial conversion price equal to $3.08 per share of the Company's common stock. The Company did not request the May advance of $10.0 million, but did request the June advance (as described above), under which this convertible note was issued.

In July 2013, the Company sold and issued a 1.5% Senior Unsecured Convertible Note to Total in the face amount of $20.0 million with a March 1, 2017 maturity date pursuant to the Total Purchase Agreement as discussed above. This purchase and sale completed Total's commitment to purchase $30.0 million of such notes by July 2013. In accordance with the March 2013 Letter Agreement, this convertible note has an initial conversion price equal to $3.08 per share of the Company's common stock.

The conversion prices of the notes issued under the Total Purchase Agreement are subject to adjustment for proportional adjustments to outstanding common stock and under anti-dilution provisions in case of certain dividends and distributions. Total has a right to require repayment of 101% of the principal amount of the notes in the event of a change of control of the Company and the notes provide for payment of unpaid interest on conversion following such a change of control if Total does not require such repayment. The Total Purchase Agreement and notes include covenants regarding payment of interest, maintenance of the Company's listing status, limitations on debt, maintenance of corporate existence, and filing of SEC reports. The notes include standard events of default resulting in acceleration of indebtedness, including failure to pay, bankruptcy and insolvency, cross-defaults, and breaches of the covenants in the purchase agreement and notes, with added default interest rates and associated cure periods applicable to the covenant regarding SEC reporting. Furthermore, the notes include restrictions on the amount of debt the Company is permitted to incur. With exceptions for certain existing debt, refinancing of such debt and certain other exclusions and waivers, the notes provide that the Company's total outstanding debt at any time cannot exceed the greater of $200.0 million or 50% of its consolidated total assets and its secured debt cannot exceed the greater of $125.0 million or 30% of its consolidated total assets. In connection with the Company’s closing of a short-term bridge loan for $35.0 million provided by Temasek in October 2013, Total waived compliance with the debt limitations outlined above as to the $35.0 million bridge loan and the August 2013 Financing.

On April 1, 2014, the Company and Total entered into a letter agreement dated as of March 29, 2014 (referred to as March 2014 Letter Agreement) to amend the Amended and Restated Master Framework Agreement entered into as of December 2, 2013 (included as part of JV Documents, as defined below) and the Total Purchase Agreement. Under the March 2014 Letter Agreement, the Company agreed to (i) amend the conversion price of the convertible notes to be issued in the third closing under the Total Purchase Agreement from $7.0682 to $4.11 (or the “New Conversion Price”) subject to stockholder approval at the Company's 2014 annual meeting (to the extent required by applicable law or regulation), (ii) extend the period during which Total may exchange for other Company securities certain outstanding convertible promissory notes issued under the July 2012 Agreements from June 30, 2014 to the later of December 31, 2014 and the date on which the Company shall have raised $75.0 million of equity and/or convertible debt financing (excluding any convertible promissory notes issued pursuant to the Total Purchase Agreement), (iii) eliminate the Company’s ability to qualify, in a disclosure letter to Total, certain of the representations and warranties that the Company must make at the closing of any third closing sale, and (iv) beginning on March 31, 2014, provide Total with monthly reporting on the Company’s cash, cash equivalents and short-term investments. In consideration of these agreements, Total agreed to waive its right not to consummate the closing of the issuance of the third closing notes if it decides not to proceed with the collaboration and makes a "No-Go" decision with respect thereto, subject to the Company obtaining stockholder approval of the issuance of the third closing notes at the New Conversion Price.

August 2013 Financing Convertible Notes and 2013 Bridge Loans

In connection with the August 2013 Financing, the Company entered into the August 2013 SPA with Total and Temasek to sell up to $73.0 million in convertible promissory notes in private placements, with such notes to be sold and issued over a period of up to 24 months from the date of signing. The August 2013 SPA provided for the August 2013 Financing to be divided into two tranches (the first tranche for $42.6 million and the second tranche for $30.4 million), each with differing closing conditions. Of the total possible purchase price in the financing, $60.0 million to be paid in the form of cash by Temasek ($35.0 million in the first tranche and up to $25.0 million in the second tranche) and $13.0 million to be paid by the exchange and cancellation of outstanding convertible promissory notes held by Total in connection with its exercise of pro rata rights ($7.6 million in the first tranche and $5.4 million in the second tranche). The August 2013 SPA included requirements that the Company meet certain production milestones before the second tranche would become available, obtain stockholder approval prior to completing any closing of the transaction, and issue a warrant to Temasek to purchase 1,000,000 shares of the Company's common stock at an exercise price of $0.01 per share, exercisable only if Total converts notes previously issued to Total in the second closing under the Total Purchase Agreement. In September 2013, prior to the initial closing of the August 2013 Financing, the Company's stockholders approved the issuance in the private placement of up to $110.0 million aggregate principal amount of senior convertible promissory notes, the issuance of a warrant to purchase 1,000,000 shares of the Company's common stock and the issuance of the common stock issuable upon conversion or exercise of such notes and warrant, which approval included the transactions contemplated by the August 2013 Financing.

In September 2013, the Company entered into a bridge loan agreement with an existing investor to provide additional cash availability of up to $5.0 million. As of March 31, 2014, the Company had not drawn any funds from the agreement and the facility expired in October 2013 in accordance with its terms.

In October 2013, the Company sold and issued a bridge note to Temasek (referred to as the “Temasek Bridge Note”) in exchange for a bridge loan of $35.0 million. The Temasek Bridge Note was due on February 2, 2014 and accrued interest at a rate of 5.5% quarterly from the October 4, 2013 date of issuance. The Temasek Bridge Note was cancelled on October 16, 2013 as payment for Temasek’s purchase of Tranche I Notes in the first tranche of the August 2013 Financing as further described below.

In October 2013, the Company amended the August 2013 SPA to include Fidelity Entities in the first tranche of the August 2013 Financing with an investment amount of $7.6 million, and to proportionally increase the amount acquired by exchange and cancellation of outstanding convertible promissory notes held by Total in connection with its exercise of pro rata rights to $14.6 million($9.2 million in the first tranche and up to $5.4 million in the second tranche). Also in October 2013, the Company completed the closing of the first tranche of the August 2013 Financing, issuing a total of $51.8 million in Tranche I Notes for cash proceeds of $7.6 million and cancellation of outstanding convertible promissory notes of $44.2 million, of which $35.0 million resulted from cancellation of the Temasek Bridge Note and the remaining $9.2 million from the exchange and cancellation of an outstanding convertible note held by Total. As a result of the exchange and cancellation of the $35.0 million Temasek Bridge Note and the $9.2 million Total convertible note for the Tranche I Notes, the Company recorded a loss from extinguishment of debt of $19.9 million. The Tranche I Notes are due sixty months from the date of issuance and will be convertible into the Company’s common stock at a conversion price equal to $2.44, which represents a 15% discount to a trailing 60-day weighted-average closing price of the common stock on NASDAQ through August 7, 2013, subject to adjustment as described below. The Tranche I Notes are convertible at the option of the holder: (i) at any time after 18 months from the date of the August 2013 SPA, (ii) on a change of control of the Company and (iii) upon the occurrence of an event of default. The conversion price of the Tranche I Notes will be reduced to $2.15 if a specified Company manufacturing plant fails to achieve a total production of 1.0 million liters within a run period of 45 days prior to June 30, 2014, the Company fails to achieve gross margins from product sales of at least 5% prior to June 30, 2014, or the Company reduces the conversion price of certain existing promissory notes held by Total prior to the repayment or conversion of the Tranche I Notes. If either of the production and margin milestones occur, and in addition, the Company reduces the conversion price of certain existing promissory notes held by Total prior to the repayment or conversion of the Tranche I Notes, the conversion price of the Tranche I Notes will be reduced to $1.87. Each Tranche I Note accrues interest from the date of issuance until the earlier of the date that such Tranche I Note is converted into the Company’s common stock or is repaid in full. Interest accrues at a rate of 5% per six months, compounded semiannually (with graduated interest rates of 6.5% applicable to the first 180 days and 8% applicable thereafter as the sole remedy should the Company fail to maintain NASDAQ listing status or at 6.5% for all other defaults). Interest for the first 30 months is payable in kind and added to the principal every six-months and thereafter, the Company may continue to pay interest in kind by adding to the principal every six-months or may elect to pay interest in cash. The Tranche I Notes may be prepaid by the Company after 30 months from the issuance date and initial interest payment; thereafter the Company has the option to prepay the Tranche I Notes every six months at the date of payment of the semi-annual coupon.


In January 2014, the Company sold and issued, for face value, approximately $34.0 million of convertible promissory notes in the second tranche of the August 2013 Financing (referred to as the “Tranche II Notes”). At the closing, Temasek purchased $25.0 million of the Tranche II Notes and Wolverine Asset Management, LLC (referred to as “Wolverine”) purchased $3.0 million of the Tranche II Notes, each for cash. Total purchased approximately $6.0 million of the Tranche II Notes through cancellation of the same amount of principal of previously outstanding convertible promissory notes held by Total. As a result of the exchange and cancellation of the $6.0 million Total convertible note for the Tranche II Notes, the Company recorded a loss from extinguishment of debt of $9.4 million. The Tranche II Notes will be due sixty months from the date of issuance and will be convertible into shares of common stock at a conversion price equal to $2.87, which represents a trailing 60-day weighted-average closing price of the common stock on NASDAQ through August 7, 2013, subject to adjustment as described below. Specifically, the Tranche II Notes are convertible at the option of the holder (i) at any time 12 months after issuance, (ii) on a change of control of the Company, and (iii) upon the occurrence of an event of default. Each Tranche II Note will accrue interest from the date of issuance until the earlier of the date that such Tranche II Note is converted into common stock or repaid in full. Interest will accrue at a rate per annum equal to 10%, compounded annually (with graduated interest rates of 13% applicable to the first 180 days and 16% applicable thereafter as the sole remedy should the Company fail to maintain NASDAQ listing status or at 12% for all other defaults). Interest for the first 36 months shall be payable in kind and added to principal every year following the issue date and thereafter, the Company may continue to pay interest in kind by adding to principal on every year anniversary of the issue date or may elect to pay interest in cash.

In addition to the conversion price adjustments set forth above, the conversion prices of the Tranche I Notes and Tranche II Notes are subject to further adjustment (i) according to proportional adjustments to outstanding common stock of the Company in case of certain dividends and distributions, (ii) according to anti-dilution provisions, and (iii) with respect to notes held by any purchaser other than Total, in the event that Total exchanges existing convertible notes for new securities of the Company in connection with future financing transactions in excess of its pro rata amount. Notwithstanding the foregoing, holders of a majority of the principal amount of the notes outstanding at the time of conversion may waive any anti-dilution adjustments to the conversion price. The purchasers have a right to require repayment of 101% of the principal amount of the notes in the event of a change of control of the Company and the notes provide for payment of unpaid interest on conversion following such a change of control if the purchasers do not require such repayment. The August 2013 SPA, Tranche I Notes and Tranche II Notes include covenants regarding payment of interest, maintenance of the Company’s listing status, limitations on debt and on certain liens, maintenance of corporate existence, and filing of SEC reports. The notes include standard events of default resulting in acceleration of indebtedness, including failure to pay, bankruptcy and insolvency, cross-defaults, and breaches of the covenants in the August 2013 SPA, Tranche I Notes and Tranche II Notes, with default interest rates and associated cure periods applicable to the covenant.

As of March 31, 2014 and December 31, 2013, $43.4 million and $37.9 million, respectively, was outstanding under the Tranche I and Tranche II Notes, net of debt discount of $34.9 million and $6.3 million, respectively. The debt discount is the result of the bifurcation of the conversion options that contain "make-whole" provisions or down round conversion price adjustment provisions associated with the outstanding debt. For the three months period ending March 31, 2014 and 2013, the Company recorded a loss from extinguishment of debt from the exchange and cancellation of related party convertible notes of $9.4 million and zero, respectively.

JVCO Convertible Notes

In December 2013, in connection with the execution of a Shareholders Agreement and License Agreement and related documents (collectively, referred to as the "JV Documents") entered into by and among Amyris, Total and Total Amyris BioSolutions B.V. (or "JVCO") relating to the establishment of JVCO (see Note 7, "Joint Venture and Noncontrolling Interest"), Amyris (i) exchanged the $69.0 million of the outstanding Total unsecured convertible notes and issued a replacement 1.5% senior secured convertible notes, in principal amounts equal to the principal amount of each cancelled note (the “Replacement Notes”), (ii) granted to Total a security interest in and lien on all Amyris’ rights, title and interest in and to Amyris’ shares in the capital of JVCO and (iii) agreed that any securities to be purchased and sold at the third closing under the Total Purchase Agreement by Total shall be 1.5%, senior secured convertible notes instead of senior unsecured convertible notes. As a consequence of executing the JV Documents and forming JVCO, the security interests in all of the Company’s intellectual property, granted by Amyris in favor of Total, Temasek, and certain Fidelity Entities pursuant the Restated Intellectual Property Security Agreement dated as of October 16, 2013, were automatically terminated effective as of December 2, 2013 upon Total’s and the Company’s joint written notice to Temasek.

As of March 31, 2014 and December 31, 2013, $47.4 million and $51.5 million, respectively, was outstanding under these notes, net of debt discount of $15.5 million and $17.6 million, respectively.

Loans Payable

In December 2009, the Company entered into a loans payable agreement with the lessor of its Emeryville pilot plant under which it borrowed a total of $0.3 million, bearing an interest rate of 10.0% per annum and to be repaid over a period of 96 months. As of March 31, 2014 and December 31, 2013, there was no amount outstanding under the loan. In June 2013, as part of the April 30, 2013 amendment entered into regarding the Company's operating lease for its headquarters, the Company recorded the elimination of this loan payable as a lease incentive and recorded approximately $0.2 million to deferred rent liability in the condensed consolidated balance sheet. The deferred rent liability is being amortized to expense over the remaining lease term.

In July 2012, the Company entered into a Note of Bank Credit and a Fiduciary Conveyance of Movable Goods Agreement (together, referred to as the "July 2012 Bank Agreements") with each of Nossa Caixa Desenvolvimento (or “Nossa Caixa”) and Banco Pine S.A. (or “Banco Pine”). Under the July 2012 Bank Agreements, the Company pledged certain farnesene production assets as collateral for the loans of R$52.0 million. The Company's total acquisition cost for such pledged assets was approximately R$68.0 million (approximately US$30.1 million based on the exchange rate as of March 31, 2014). The Company is also a parent guarantor for the payment of the outstanding balance under these loan agreements. Under the July 2012 Bank Agreements, the Company could borrow an aggregate of R$52.0 million (approximately US$22.2 million based on the exchange rate as of March 31, 2014) as financing for capital expenditures relating to the Company's manufacturing facility located in Brotas, Brazil. Specifically, Banco Pine, agreed to lend R$22.0 million and Nossa Caixa agreed to lend R$30.0 million. The funds for the loans are provided by BNDES, but are guaranteed by the lenders. The loans have a final maturity date of July 15, 2022 and bear a fixed interest rate of 5.5% per year. The loans are also subject to early maturity and delinquency charges upon occurrence of certain events including interruption of manufacturing activities at the Company's manufacturing facility in Brotas, Brazil for more than 30 days, except during sugarcane off-season. For the first two years that the loans are outstanding, the Company is required to pay interest only on a quarterly basis. After August 15, 2014, the Company is required to pay equal monthly installments of both principal and interest for the remainder of the term of the loans. As of March 31, 2014 and December 31, 2013, a principal amount of $23.0 million and $22.2 million, respectively, was outstanding under these loan agreements.

In October 2013, the Company borrowed $0.6 million from a third party lender to pay for the Company's current insurance premiums. The loan is payable in nine monthly installments of principal and interest. Interest accrues at a rate of 3.24% per annum. As of March 31, 2014 and December 31, 2013, the outstanding unpaid loan balance was $0.2 million and $0.4 million, respectively.

In February 2014, the Company borrowed $0.2 million from a third party lender to pay for the Company's consolidated VIE's current insurance premiums. The loan is payable in ten monthly installments of principal and interest. Interest accrues at a rate of 5.95% per annum. As of March 31, 2014 and December 31, 2013, the outstanding unpaid loan balance was $0.2 million and zero, respectively.

In March 2013, the Company entered into a one-year-term export financing agreement with ABC for approximately $2.5 million to fund exports through March 2014. This loan is collateralized by future exports from the Company's subsidiary in Brazil. As of March 31, 2014, the loan was fully paid.

In March 2014, the Company entered into an additional a one-year-term export financing agreement with ABC for approximately 2.2 million to fund exports through March 2015. This loan is collateralized by future exports from the Company's subsidiary in Brazil. As of March 31, 2014, the principal amount outstanding under this agreement was $2.2 million.


Letters of Credit

In June 2012, the Company entered into a letter of credit agreement for $1.0 million under which it provided a letter of credit to the landlord of its headquarters in Emeryville, California, in order to cover the security deposit on the lease. This letter of credit is secured by a certificate of deposit. Accordingly, the Company has $0.9 million as restricted cash as of March 31, 2014 and December 31, 2013.

Future minimum payments under the debt agreements as of March 31, 2014 are as follows (in thousands):

	Lease Obligations

	The Company leases certain facilities and finances certain equipment under operating and capital leases, respectively. Operating leases include leased facilities and capital leases include leased equipment (see Note 4, "Balance Sheet Components"). The Company recognizes rent expense on a straight-line basis over the non-cancellable lease term and records the difference between rent payments and the recognition of rent expense as a deferred rent liability. Where leases contain escalation clauses, rent abatements, and/or concessions, such as rent holidays and landlord or tenant incentives or allowances, the Company applies them as a straight-line rent expense over the lease term. The Company has non-cancellable operating lease agreements for office, research and development, and manufacturing space that expire at various dates, with the latest expiration in February 2031. Rent expense under operating leases was $1.4 million and $0.7 million for the three months period ended March 31, 2014 and 2013, respectively.

	Future minimum payments under the Company's lease obligations as of March 31, 2014, are as follows (in thousands):

	Guarantor Arrangements

	The Company has agreements to indemnify its officers and directors for certain events or occurrences while the officers or directors are serving in their official capacities. The indemnification period remains enforceable for the officer's or director’s lifetime. The maximum potential amount of future payments the Company could be required to make under these indemnification agreements is unlimited; however, the Company has a director and officer insurance policy that limits its exposure and enables the Company to recover a portion of any future payments. As a result of its insurance policy coverage, the Company believes the estimated fair value of these indemnification agreements is minimal. Accordingly, the Company had no liabilities recorded for these agreements as of March 31, 2014 and December 31, 2013.

	The Company entered into the FINEP Credit Facility to finance a research and development project on sugarcane-based biodiesel (see Note 5, "Debt"). The FINEP Credit Facility is guaranteed by a chattel mortgage on certain equipment of the Company. The Company's total acquisition cost for the equipment under this guarantee is approximately R$6.0 million (approximately US$2.7 million based on the exchange rate as of March 31, 2014).

	The Company entered into the BNDES Credit Facility to finance a production site in Brazil (see Note 5, "Debt").The BNDES Credit Facility is collateralized by a first priority security interest in certain of the Company's equipment and other tangible assets with a total acquisition cost of R$24.9 million (approximately US$11.0 million based on the exchange rate as of March 31, 2014). The Company is a parent guarantor for the payment of the outstanding balance under the BNDES Credit Facility. Additionally, the Company is required to provide certain bank guarantees under the BNDES Credit Facility. Accordingly, the Company has a $0.7 million and $0.7 million as restricted cash as of March 31, 2014 and December 31, 2013, respectively.

	The Company entered into loan agreements and security agreement where the Company pledged certain farnesene production assets as collateral (the fiduciary conveyance of movable goods) with each of Nossa Caixa and Banco Pine (see Note 5, "Debt"). The Company's total acquisition cost for the farnesene production assets pledged as collateral under these agreements is approximately R$68.0 million (approximately US$30.1 million based on the exchange rate as of March 31, 2014). The Company is also a parent guarantor for the payment of the outstanding balance under these loan agreements.

	The Company has an export financing agreement for approximately $2.5 million for a one year term to fund exports through March 2014. This loan is collateralized by future exports from the Amyris Brasil. As of March 31, 2014 the loan was fully paid. The Company has signed another export financing agreement with the same bank for approximately $2.2 million for a one year term to fund exports through March 2015. The Company is in the process of providing its guarantee for this financing arrangement.

	Under an operating lease agreement for its office facilities in Brazil, which commenced on November 15, 2011, the Company is required to maintain restricted cash or letters of credit equal to 3 months of rent of approximately R$0.2 million (approximately US$0.1 million based on the exchange rate as of March 31, 2014) in the aggregate as a guarantee that the Company will meet its performance obligations under such operating lease agreement.

	In October 2013, the Company entered into a letter agreement with Total relating to the Temasek Bridge Note and to the closing of the August 2013 Financing (referred to as the "Amendment Agreement") (see Note 5, "Debt"). In the August 2013 Financing, the Company was required to provide the purchasers under the August 2013 SPA with a security interest in the Company’s intellectual property if Total still held such security interest as of the initial closing of the August 2013 Financing. Under the terms of a previous Intellectual Property Security Agreement by and between the Company and Total (referred to as the "Security Agreement"), the Company had previously granted a security interest in favor of Total to secure the obligations of the Company under certain convertible promissory notes issued and issuable to Total under the Company’s purchase agreement with Total. The Security Agreement provided that such security interest would terminate if Total and the Company entered into certain agreements relating to the formation of the Fuels JV. In connection with Total’s agreement to (i) permit the Company to grant the security interest under the Temasek Bridge Note and the August 2013 Financing and (ii) waive a secured debt limitation contained in the outstanding convertible promissory notes held by Total (referred to as the “Total Securities”), the Company entered into the Amendment Agreement. Under the Amendment Agreement, the Company agreed to reduce, effective December 2, 2013, the conversion price for the Total Securities issued in 2012 (approximately $48.3 million of which are outstanding as of the date hereof) from $7.0682 per share to $2.20, the market price per share of the Company’s common stock as of the signing of the Amendment Agreement, as determined in accordance with applicable NASDAQ rules, unless the Company and Total entered into the JV Documents on or prior to December 2, 2013. The Company and Total entered into the JV agreements on December 2, 2013 and the Amendment Agreement and all security interests thereunder were automatically terminated.

	In December 2013, in connection with the execution of JV Documents entered into by and among Amyris, Total and JVCO relating to the establishment of the JVCO (see Note 5, "Debt" and Note 7, "Joint Venture and Noncontrolling Interest"), Amyris agreed to exchange the $69.0 million outstanding Total unsecured convertible notes and issue replacement 1.5% senior secured convertible notes, in principal amounts equal to the principal amount of each Replacement Notes and grant a security interest to Total in and lien on all Amyris’ rights, title and interest in and to Amyris’ shares in the capital of the JVCO. Following execution of the JV Documents, all notes that may be issued in connection with the third closing under the Total Purchase Agreement between Total and the Company (up to $21.7 million in the aggregate; with up to $10.9 million in principal amount of such remaining notes to be issued by July 31, 2014, and up to an additional $10.9 millionin principal amount of such remaining notes to be issued by January 31, 2015) shall be senior secured convertible notes instead of senior unsecured convertible notes.

	In March 2014, The Company and Hercules Technology Growth Capital, Inc. entered into a loan and security agreement to make available to the Company a loan in the aggregate principal amount of up to$25.0 million. Loans under the facility are secured by various liens, including a lien on certain Company intellectual property. In connection with the Hercules loan, the Company agreed to certain customary representations and warranties and covenants, as well as certain covenants with respect to obtaining additional financing as described above and performance covenants related to revenues and cash flows starting with the third quarter of 2014. If the Company does not achieve the equity financing covenant, a forbearance fee of $10.0 million becomes due and is required to be paid at the end of the initial term of the loan. The Company borrowed the full amount available under the facility and received the funds on March 31, 2014.

	Purchase Obligations

	As of March 31, 2014, the Company had $8.6 million in purchase obligations which included $8.1 million in non-cancellable contractual obligations and construction commitments, of which $4.0 million have been accrued as loss on purchase commitments.

	Other Matters

	Certain conditions may exist as of the date the financial statements are issued, which may result in a loss to the Company but will only be recorded when one or more future events occur or fail to occur. The Company's management assesses such contingent liabilities, and such assessment inherently involves an exercise of judgment. In assessing loss contingencies related to legal proceedings that are pending against and by the Company or unasserted claims that may result in such proceedings, the Company's management evaluates the perceived merits of any legal proceedings or unasserted claims as well as the perceived merits of the amount of relief sought or expected to be sought.

	If the assessment of a contingency indicates that it is probable that a material loss has been incurred and the amount of the liability can be estimated, then the estimated liability would be accrued in the Company's financial statements. If the assessment indicates that a potential material loss contingency is not probable but is reasonably possible, or is probable but cannot be estimated, then the nature of the contingent liability, together with an estimate of the range of possible loss if determinable and material would be disclosed. Loss contingencies considered to be remote by management are generally not disclosed unless they involve guarantees, in which case the guarantee would be disclosed.

In May 2013, a securities class action complaint was filed against the Company and its CEO, John G. Melo, in the U.S. District Court for the Northern District of California. In October 2013, the lead plaintiffs filed a consolidated amended complaint. The complaint, as amended, sought unspecified damages on behalf of a purported class that would comprise all individuals who acquired the Company's common stock between April 29, 2011 and February 8, 2012. The complaint alleged securities law violations based on the Company's commercial projections during that period. In December 2013, the Company filed a motion to dismiss the complaint. In March 2014, the court issued an order granting the Company's motion to dismiss with leave to amend the complaint. The Company believes the complaint lacks merit, and intends to defend itself vigorously. Because the case is at a very early stage and no specific monetary demand has been made, it is not possible for us to estimate the potential loss or range of potential losses for the case.

In August 2013, a complaint entitled Steve Shannon, derivatively on behalf of Amyris, Inc. v. John G. Melo et al and Amyris, Inc., was filed against the Company as nominal defendant in the United States District Court for the Northern District of California. The lawsuit seeks unspecified damages on behalf of the Company from certain of its current and former officers, directors and employees and alleges these defendants breached their fiduciary duties to the Company and unjustly enriched themselves by making allegedly false and misleading statements and omitting certain material facts in the Company's securities filings. Because this purported stockholder derivative action is based on substantially the same facts as the securities class action described above, the two actions have been related and will be heard by the same judge. By stipulation of the parties, the case has been stayed until the Company either files an answer in the securities class action or the securities action is dismissed with prejudice. The Company does not believe the claims in the complaint have merit, and intends to defend itself vigorously. Because the case is at a very early stage and no specific monetary demand has been made, it is not possible to estimate the potential loss or range of potential losses for the case.

The Company is subject to disputes and claims that arise or have arisen in the ordinary course of business and that have not resulted in legal proceedings or have not been fully adjudicated. Such matters that may arise in the ordinary course of business are subject to many uncertainties and outcomes are not predictable with assurance. Therefore, if one or more of these legal disputes or claims resulted in settlements or legal proceedings that were resolved against the Company for amounts in excess of management’s expectations, the Company’s consolidated financial statements for the relevant reporting period could be materially adversely affected.

	Joint Ventures and Noncontrolling Interest

	SMA Indústria Química S.A.

	In April 2010, the Company established SMA Indústria Química (or "SMA"), a joint venture with Sao Martinho S.A. (or "SMSA") (formerly Usina São Martinho S.A.), to build a production facility in Brazil. SMA is located at the SMSA mill in Pradópolis, São Paulo state. The joint venture agreements establishing SMA have a 20 year initial term.

	SMA is managed by a three member executive committee, of which the Company appoints two members, one of whom is the plant manager who is the most senior executive responsible for managing the construction and operation of the facility. SMA is governed by a four member board of directors, of which the Company and SMSA each appoint two members. The board of directors has certain protective rights which include final approval of the engineering designs and project work plan developed and recommended by the executive committee.

	The joint venture agreements require the Company would fund the construction costs of the new facility and SMSA would reimburse the Company up to R$61.8 million (approximately US$27.3 million based on the exchange rate as of March 31, 2014) of the construction costs after SMA commences production. After commercialization, the Company would market and distribute Amyris renewable products produced by SMA and SMSA would sell feedstock and provide certain other services to SMA. The cost of the feedstock to SMA would be a price that is based on the average return that SMSA could receive from the production of its current products, sugar and ethanol. The Company would be required to purchase the output of SMA for the first four years at a price that guarantees the return of SMSA’s investment plus a fixed interest rate. After this four year period, the price would be set to guarantee a break-even price to SMA plus an agreed upon return.

	Under the terms of the joint venture agreements, if the Company becomes controlled, directly or indirectly, by a competitor of SMSA, then SMSA has the right to acquire the Company’s interest in SMA. If SMSA becomes controlled, directly or indirectly, by a competitor of the Company, then the Company has the right to sell its interest in SMA to SMSA. In either case, the purchase price shall be determined in accordance with the joint venture agreements, and the Company would continue to have the obligation to acquire products produced by SMA for the remainder of the term of the supply agreement then in effect even though the Company would no longer be involved in SMA’s management.

	The Company has a 50% ownership interest in SMA. The Company has identified SMA as a variable interest entity (or "VIE") pursuant to the accounting guidance for consolidating VIEs because the amount of total equity investment at risk is not sufficient to permit SMA to finance its activities without additional subordinated financial support, as well as because the related commercialization agreement provides a substantive minimum price guarantee. Under the terms of the joint venture agreement, the Company directs the design and construction activities, as well as production and distribution. In addition, the Company has the obligation to fund the design and construction activities until commercialization is achieved. Subsequent to the construction phase, both parties equally fund SMA for the term of the joint venture. Based on those factors, the Company was determined to have the power to direct the activities that most significantly impact SMA’s economic performance and the obligation to absorb losses and the right to receive benefits. Accordingly, the financial results of SMA are included in the Company’s consolidated financial statements and amounts pertaining to SMSA’s interest in SMA are reported as noncontrolling interests in subsidiaries.

	The Company completed a significant portion of the construction of the new facility in 2012. The Company suspended construction of the facility in order to focus on completing and operating the Company's smaller production facility in Brotas, Brazil. In February 2014, the Company entered into an amendment to the joint venture agreement with SMSA which updated and documented certain preexisting business plan requirements related to the start-up of construction at the joint venture operated plant and set forth, among other things, (i) the extension of the deadline for the commencement of operations at the joint venture operated plant to no later than 18 months following the construction of the plant, which shall occur no later than March 31, 2017, and (ii) the extension of an option held by SMSA to build a second large-scale farnesene production facility to no later than December 31, 2018 with the commencement of operations at such second facility to occur no later than April 1, 2019.

	Novvi S.A.

	In June 2011, the Company entered into joint venture agreements with Cosan Combustíveis e Lubrificantes S.A. and Cosan S.A. Industria e Comércio (such Cosan entities, collectively or individually, “Cosan”), related to the formation of a joint venture to focus on the worldwide development, production and commercialization of base oils made from Biofene for the automotive, commercial and industrial lubricants markets (referred to as the "Original JV Agreement"). The parties originally envisioned operating their joint venture through Novvi S.A., a Brazilian entity jointly owned by Cosan and Amyris Brasil.

	Under the Original JV Agreement and related agreements, the Company and Cosan each owned 50% of the Novvi S.A. and each party would share equally in any costs and any profits ultimately realized by Novvi S.A. The joint venture agreement had an initial term of 20 years from the date of the Original JV Agreement, subject to earlier termination by mutual written consent or by a non-defaulting party in the event of specified defaults by the other party. The shareholders' agreement had an initial term of 10 years from the date of the agreement, subject to earlier termination if either the Company or Cosan ceases to own at least 10% of the voting stock of Novvi S.A. Since its formation, Novvi S.A. had minimal operating activities while the Company and Cosan continued to determine and finalize the strategy and operating activities for the joint venture. Upon determination by the Company and Cosan that the joint venture should be operated out of a U.S. entity, the operating activities of Novvi S.A. ceased. The Company has identified that Novvi S.A. is a VIE and determined that the power to direct activities, which most significantly impact the economic success of the joint venture, is equally shared between the Company and Cosan. Accordingly, the Company is not the primary beneficiary and therefore accounts for its investment in Novvi S.A. under the equity method of accounting.

	In March 2013, the Company, Amyris Brasil and Cosan entered into a termination agreement to terminate the Original JV Agreement. In addition, Amyris Brasil agreed to sell, its 50% ownership in Novvi S.A. for approximately R$22,000 which represented the current value of its 50% equity ownership in Novvi S.A., a now-dormant company, to Cosan. Upon the consummation of the transaction with the shares transferring from Amyris Brasil to Cosan, the Novvi S.A. shareholders agreement automatically terminated.

	Novvi LLC

	In September 2011, the Company and Cosan US, Inc. (or Cosan U.S.) formed Novvi LLC, a U.S. entity that is jointly owned by the Company and Cosan U.S. (or "Novvi"). In March 2013, the Company and Cosan U.S. entered into agreements to (i) expand their base oils joint venture to also include additives and lubricants and (ii) operate their joint venture exclusively through Novvi. Specifically, the parties entered into an Amended and Restated Operating Agreement for Novvi (referred to as the "Operating Agreement"), which sets forth the governance procedures for Novvi and the joint venture and the parties' initial contribution. The Company also entered into an IP License Agreement with Novvi (referred to as the "IP License Agreement") under which the Company granted Novvi (i) an exclusive (subject to certain limited exceptions for the Company), worldwide, royalty-free license to develop, produce and commercialize base oils, additives, and lubricants derived from Biofene for use in automotive and industrial lubricants markets and (ii) a non-exclusive, royalty-free license, subject to certain conditions, to manufacture Biofene solely for its own products. In addition, both the Company and Cosan U.S. granted Novvi certain rights of first refusal with respect to alternative base oil and additive technologies that may be acquired by the Company or Cosan U.S. during the term of the IP License Agreement. Under these agreements, the Company and Cosan U.S. will each own 50% of Novvi and each party will share equally in any costs and any profits ultimately realized by the joint venture. Novvi is governed by a six member Board of Managers (or the "Board Managers"), with three managers represented by each investor. The Board of Managers appoints the officers of Novvi, who are responsible for carrying out the daily operating activities of Novvi as directed by the Board of Managers. The IP License Agreement has an initial term of 20 years from the date of the agreement, subject to standard early termination provisions such as uncured material breach or a party's insolvency. Under the terms of the Operating Agreement, Cosan U.S. is obligated to fund its 50% ownership share of Novvi in cash in the amount of $10.0 million and the Company is obligated to fund its 50% ownership share of Novvi through the granting of an IP License to develop, produce and commercialize base oils, additives, and lubricants derived from Biofene for use in the automotive, commercial and industrial lubricants markets which has been agreed upon by Cosan U.S. and Amyris valued at $10.0 million. In March 2013, the Company measured its initial contribution of intellectual property to Novvi at the Company's carrying value of the licenses granted under the IP License Agreement, which was zero. Additional funding requirements to finance the ongoing operations of Novvi are expected to happen through revolving credit or other loan facilities provided by unrelated parties (i.e. such as financial institutions); cash advances or other credit or loan facilities provided by the Company and Cosan U.S. or their affiliates; or additional capital contributions by the Company and Cosan U.S.

	The Company has identified Novvi as a VIE and determined that the power to direct activities, which most significantly impact the economic success of the joint venture (i.e. continuing research and development, marketing, sales, distribution and manufacturing of Novvi products), is equally shared between the Company and Cosan U.S. Accordingly, the Company is not the primary beneficiary and therefore accounts for its investment in Novvi under the equity method of accounting. The Company will continue to reassess its primary beneficiary analysis of Novvi if there are changes in events and circumstances impacting the power to direct activities that most significantly affect Novvi's economic success. Under the equity method, the Company's share of profits and losses are included in “Other income (expense), net” in the condensed consolidated statements of operations. For the three month period ended March 31, 2014, the Company recorded no amounts for its share of Novvi's net loss as the carrying amount of the Company's investment in Novvi was zero and losses in excess of the carrying amount were offset by the accretion of the Company's share in the basis difference resulting from the parties' initial contribution. The Company recorded zero and $2.5 million of revenue from the research and development activities that it has performed on behalf of Novvi for the three months period ended March 31, 2014 and 2013, respectively.

	Total Amyris BioSolutions B.V.

	In November 2013, the Company and Total formed JVCO. The common equity of JVCO is jointly owned (50%/50%) by the Company and Total, and the preferred equity of JVCO is 100% owned by the Company. The Parties have agreed that JVCO’s purpose is limited to executing the License Agreement and maintaining such licenses under it, unless and until either (i) Total elects to go forward with either the full (diesel and jet fuel) JVCO commercialization program or the jet fuel component of the JVCO commercialization program (referred to as a “Go Decision”), (ii) Total elects to not continue its participation in the R&D Program and JVCO (referred to as a “No-Go Decision”), or (iii) Total exercises any of its rights to buy out the Company’s interest in JVCO. Following a Go Decision, the articles and shareholders’ agreement would be amended and restated to be consistent with the shareholders’ agreement contemplated by the July 2012 Agreements (see Note 5, "Debt" and Note 8, "Significant Agreements").

	The JVCO has an initial capitalization of €0.1 million (approximately US$0.1 million based on the exchange rate as of March 31, 2014). The Company has identified JVCO as a VIE and determined that the Company is not the primary beneficiary and therefore accounts for its investment in JVCO under the equity method of accounting. Under the equity method, the Company's share of profits and losses are included in "Other income (expense), net" in the condensed consolidated statements of operations. No later than six months prior to July 31, 2016, the Company and Total shall amend the July 2012 Agreements to reflect the corporate structure of JVCO, amend and restate the articles of association of JVCO, finalize and agree on a five-year plan and an initial budget, maximize economic viability and value of JVCO and enter into the Total license agreement. The Company will reevaluate its assessment in 2016 based on the specific terms of the final shareholders' agreement.

	Glycotech

	In January 2011, the Company entered into a production service agreement (referred to as the "Glycotech Agreement") with Glycotech, Inc. (or "Glycotech"), under which Glycotech provides process development and production services for the manufacturing of various Company products at its leased facility in Leland, North Carolina. The Company products manufactured by Glycotech are owned and distributed by the Company. Pursuant to the terms of the production Glycotech Agreement, the Company is required to pay the manufacturing and operating costs of the Glycotech facility, which is dedicated solely to the manufacture of Amyris products. The initial term of the Glycotech Agreement was for a two year period commencing on February 1, 2011 and the Glycotech Agreement renews automatically for successive one-year terms, unless terminated by the Company. Concurrent with the Glycotech Agreement, the Company also entered into a Right of First Refusal Agreement with the lessor of the facility and site leased by Glycotech (referred to as the "ROFR Agreement"). Per conditions of the ROFR Agreement, the lessor agreed not to sell the facility and site leased by Glycotech during the term of the Glycotech Agreement. In the event that the lessor is presented with an offer to sell or decides to sell an adjacent parcel, the Company has the right of first refusal to acquire it.

	The Company has determined that the arrangement with Glycotech qualifies as a VIE. The Company determined that it is the primary beneficiary of this arrangement since it has the power through the management committee over which it has majority control to direct the activities that most significantly impact Glycotech's economic performance. In addition, the Company is required to fund 100% of Glycotech's actual operating costs for providing services each month while the facility is in operation under the Glycotech Agreement. Accordingly, the Company consolidates the financial results of Glycotech. As of March 31, 2014, the carrying amounts of the consolidated VIE's assets and liabilities were not material to the Company's condensed consolidated financial statements.

	The table below reflects the carrying amount of the assets and liabilities of the two consolidated VIEs for which the Company is the primary beneficiary. As of March 31, 2014, the assets include $22.3 million in property, plant and equipment, $4.0 million in other assets and $0.5 million in current assets. The liabilities include $0.2 million in accounts payable and accrued current liabilities and $0.3 million in loan obligations by Glycotech to its shareholders that are non-recourse to the Company. The creditors of each consolidated VIE have recourse only to the assets of that VIE.

	Collaboration Partner Joint Development and License Agreement

	In April 2013, the Company entered into a joint development and license agreement with a collaboration partner. Under the terms of the multi-year agreement, the collaboration partner and the Company will jointly develop certain fragrance ingredients. The collaboration partner will have exclusive rights to these fragrance ingredients for applications in the flavors and fragrances field, and the Company will have exclusive rights in other fields. The collaboration partner and the Company will share in the economic value derived from these ingredients. The joint development and license agreement provided for up to $6.0 million in funding based upon the achievement of certain technical milestones which are considered substantive by the Company during the first phase of the collaboration.

	In February 2014, the Company entered into an amendment to the joint development and license agreement with the collaboration partner noted in the preceding paragraph to proceed with the second phase of the collaboration and the development of a certain fragrance ingredient. For the three months period ended March 31, 2014 revenue recognized under this agreement was not material.

	Collaboration Partner Master Collaboration and Joint Development Agreement

	In March 2013, the Company entered into a Master Collaboration Agreement with the collaboration partner to establish a collaboration for the development and commercialization of multiple renewable flavors and fragrances (referred to as "F&F") compounds. Under this agreement, except for rights granted under preexisting collaboration relationships, the Company granted the collaboration partner exclusive access for such compounds to specified Company intellectual property for the development and commercialization of F&F products in exchange for research and development funding and a profit sharing arrangement. The agreement superseded and expanded the prior collaboration agreement between the Company and collaboration partner.

	The agreement provides annual, up-front funding to the Company by the collaboration partner of $10.0 million for each of the first three years of the collaboration. The initial payment of $10.0 million was received by the Company in March 2013 and the second payment was received in March 2014. For the three months period ended March 31, 2014 and 2013, the Company recognized revenue of $2.5 million and $0.4 million under this agreement. The agreement contemplates additional funding by the collaboration partner of up to $5.0 million under three potential milestone payments, as well as additional funding by the collaboration partner on a discretionary basis.

	Kuraray Collaboration Agreement

	In March 2014, the Company entered into the Second Amended and Restated Collaboration Agreement with Kuraray Co., Ltd. (or “Kuraray”) in order to extend the term of the original agreement dated July 21, 2011 for an additional two years and add additional fields and products to the scope of development. In consideration for the Company’s agreement to extend the term of the original collaboration agreement and add additional fields and products, Kuraray will pay the Company $4.0 million in two (2) equal installments of $2.0 million with due dates of April 30, 2014 and April 30, 2015.

	The intangible assets acquired through the Draths Corporation acquisition in October 2011 of in-process research and development of $8.6 million and goodwill of $0.6 million are treated as indefinite lived intangible assets until completion or abandonment of the projects, at which time the assets will be amortized over the remaining useful life or written-off, as appropriate. If the carrying amount of the assets is greater than the measures of fair value, impairment is considered to have occurred and a write-down of the asset is recorded. Any finding that the value of its intangible assets has been impaired would require the Company to write-down the impaired portion, which could reduce the value of its assets and reduce (increase) its net income (loss) for the year in which the related impairment charges occur. As of March 31, 2014 and December 31, 2013, no impairment of the goodwill and intangible assets was recorded.

	Acquired licenses and permits are amortized using a straight-line method over its estimated useful life. Amortization expense for this intangible was zero and $32,000 for the three months period ended March 31, 2014 and 2013, respectively. As of March 31, 2014, acquired licenses and permits were fully amortized.

	Evergreen Shares for 2010 Equity Plan and 2010 ESPP

	In January 2014, the Company's Board of Directors (or "Board") approved an increase to the number of shares available for issuance under the Company's 2010 Equity Incentive Plan (or "Equity Plan") and the 2010 Employee Stock Purchase Plan (or "ESPP"). These shares represent an automatic annual increase in the number of shares available for issuance under the Equity Plan and the ESPP of 3,833,141 and 766,628, respectively. These increases equal 5% and 1%, respectively of 76,662,812 shares, the total outstanding shares of the Company’s common stock as of December 31, 2013. This automatic increase was effective as of January 1, 2014. Shares available for issuance under the Equity Plan and ESPP were initially registered on a registration statement on Form S-8 filed with the Securities and Exchange Commission on October 1, 2010 (Registration No. 333-169715). The Company filed registration statements on Form S-8 on April 14, 2014 (Registration No. 333-195259) with respect to the shares added by the automatic increase on January 1, 2014.

	Common Stock

	As of December 31, 2013, the Company was authorized to issue 200,000,000 shares of common stock pursuant to the Company’s amended and restated certificate of incorporation. The Board has approved and submitted to the Company’s stockholders for approval at the Company’s 2014 Annual meeting of stockholders the amendment of the Company’s certificate of incorporation to increase its authorized number of shares of common stock to 300,000,000. Assuming approval by the Company's stockholders, such amendment to the certificate of incorporation would become effective as soon as practicable following the Company's annual meeting. Holders of the Company’s common stock are entitled to dividends as and when declared by the Board, subject to the rights of holders of all classes of stock outstanding having priority rights as to dividends. There have been no dividends declared to date. The holder of each share of common stock is entitled to one vote.

	Preferred Stock

	Pursuant to the Company’s certificate of incorporation, the Company is authorized to issue 5,000,000 shares of preferred stock. The Board has the authority, without action by its stockholders, to designate and issue shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof. As of March 31, 2014 and March 31, 2013, the Company had no convertible preferred stock outstanding.

	Common Stock Warrants

	In December 2011, in connection with a capital lease agreement, the Company issued warrants to purchase 21,087 shares of the Company's common stock at an exercise price of $10.67 per share. The Company estimated the fair value of these warrants as of the issuance date to be $0.2 million and recorded these warrants as other assets, amortizing them subsequently over the term of the lease. The fair value was based on the contractual term of the warrants of 10 years, risk free interest rate of 2%, expected volatility of 86% and zero expected dividend yield. These warrants remain unexercised and outstanding as of March 31, 2014.

	In October 2013, in connection with the issuance of the Temasek Tranche I Notes (see Note 5, "Debt"), the Company issued contingently exercisable warrants to purchase 1,000,000 shares of the Company's common stock at an exercise price of $0.01 per share. The Company estimated the fair value of these warrants as of the issuance date at $1.3 million and recorded these warrants as debt issuance cost to be amortized over the term of the note. The fair-value was calculated using a Monte Carlo simulation valuation model based on the contractual term of the warrants of 3.4 years, risk free interest rate of 0.77%, expected volatility of 45% and zero expected dividend yield. These warrants remain unexercised and outstanding as of March 31, 2014.

	Each of these warrants includes a cashless exercise provision which permits the holder of the warrant to elect to exercise the warrant without paying the cash exercise price, and receive a number of shares determined by multiplying (i) the number of shares for which the warrant is being exercised by (ii) the difference between the fair market value of the stock on the date of exercise and the warrant exercise price, and dividing such by (iii) the fair market value of the stock on the date of exercise. During three months period ended March 31, 2014 and 2013, no warrants were exercised through the cashless exercise provision.

Stock-Based Compensation Expense

Stock-based compensation expense related to options and restricted stock units granted to employees and nonemployees was allocated to research and development expense and sales, general and administrative expense as follows (in thousands):



	Three Months Ended March 31,
	2014				2013

Research and development	$	798			$	1,247

Sales, general and administrative	2,716				2,946

Total stock-based compensation expense	$	3,514			$	4,193


.

As of March 31, 2014, there was unrecognized compensation expense of $12.7 million related to stock options, and the Company expects to recognize this expense over a weighted average period of 2.53 years. As of March 31, 2014, there was unrecognized compensation expense of $2.8 million related to RSUs, and the Company expects to recognize this expense over a weighted average period of 1.53 years.


Stock-based compensation expense for RSUs is measured based on the closing fair market value of the Company's common stock on the date of grant. Stock-based compensation expense for stock options and employee stock purchase plan rights is estimated at the grant date and offering date, respectively, based on the fair-value using the Black-Scholes option pricing model. The fair value of employee stock options is being amortized on a straight-line basis over the requisite service period of the awards. The fair value of employee stock options was estimated using the following weighted-average assumptions:



	Three Months Ended March 31,
	2014			2013
Expected dividend yield	—	%		—	%
Risk-free interest rate	2	%		1.2	%
Expected term (in years)	6.2			6.1

Expected volatility	76	%		84	%

Expected Dividend Yield—The Company has never paid dividends and does not expect to pay dividends.

Risk-Free Interest Rate—The risk-free interest rate was based on the market yield currently available on United States Treasury securities with maturities approximately equal to the option’s expected term.

Expected Term—Expected term represents the period that the Company’s stock-based awards are expected to be outstanding. The Company’s assumptions about the expected term have been based on that of companies that have similar industry, life cycle, revenue, and market capitalization and the historical data on employee exercises.

Expected Volatility—The expected volatility is based on a combination of historical volatility for the Company's stock and the historical stock volatilities of several of the Company’s publicly listed comparable companies over a period equal to the expected terms of the options, as the Company does not have a long trading history.

Forfeiture Rate—The Company estimates its forfeiture rate based on an analysis of its actual forfeitures and will continue to evaluate the adequacy of the forfeiture rate based on actual forfeiture experience, analysis of employee turnover behavior, and other factors. The impact from a forfeiture rate adjustment will be recognized in full in the period of adjustment, and if the actual number of future forfeitures differs from that estimated by the Company, the Company may be required to record adjustments to stock-based compensation expense in future periods.

Each of the inputs discussed above is subjective and generally requires significant management and director judgment.

Nonemployee Stock–Based Compensation

During each of the three months period ended March 31, 2014 and 2013, the Company granted nonemployee options to purchase 20,000 shares of its common stock, respectively, to nonemployees in exchange for services. Compensation expense of $42,000 and $15,000 was recorded for the three months period ended March 31, 2014 and 2013, respectively, for stock-based options granted to nonemployees. The nonemployee options were valued using the Black-Scholes option pricing model.

During the three months period ended March 31, 2014 and 2013, no restricted stock units, were granted to nonemployees. A reduction of $3,000 and $24,000 in stock-based compensation expense was recorded by the Company for the three months period ended March 31, 2014 and 2013, respectively, for the restricted stocks granted to nonemployees.

The fair value of nonemployee stock options was estimated using the following weighted-average assumptions:



	Three Months Ended March 31,

Expected dividend yield	—	%		—	%
Risk-free interest rate	1.8	%		1.3	%

	In March 2013 and March 2014, respectively, the Company entered into letter agreements with Total that reduced the respective conversion prices of certain convertible promissory notes issuable under the Total Purchase Agreement, as described under “Related Party Convertible Notes” in Note 5, "Debt."

	Related Party Financings

	In March 2013, the Company completed a private placement of 1,533,742 shares of its common stock to an existing stockholder, Biolding Investment SA ("Biolding"), at a price of $3.26 per share for aggregate proceeds of $5.0 million. This private placement represented the final tranche of Biolding's preexisting contractual obligation to fund $15.0 million upon satisfaction by the Company of certain criteria associated with the commissioning of the Company's production plant in Brotas, Brazil.

	In June 2013, the Company sold and issued a 1.5% Senior Unsecured Convertible Note to Total in the face amount of $10.0 million with a March 1, 2017 maturity date pursuant to the Total Purchase Agreement as discussed above under “Related Party Convertible Notes” in Note 5, “Debt."

	In July 2013, the Company sold and issued a 1.5% Senior Unsecured Convertible Note to Total in the face amount of $20.0 million with a March 1, 2017 maturity date pursuant to the Total Purchase Agreement as discussed above under “Related Party Convertible Notes” in Note 5, “Debt."

	In August 2013, the Company entered into a securities purchase agreement by and among the Company, Total and Temasek, each a beneficial owner of more than 5% of the Company's existing common stock at the time of the transaction, for a private placement of convertible promissory notes in an aggregate principal amount of $73.0 million. The initial closing of the August 2013 Financing was completed in October 2013 for the sale of approximately$42.6 million of these Tranche I Notes and the second closing of the August 2013 Financing for the sale of approximately $30.4 million of these Tranche II Notes was completed in January 2014.

	In September 2013, the Company entered into a bridge loan agreement with an existing investor to provide additional cash availability of up to $5.0 million as needed before the initial closing of the August 2013 Financing. The Company did not use this facility and it expired in October 2013 in accordance with its terms.

	In October 2013, the Company sold and issued a senior secured promissory note to Temasek for a bridge loan of $35.0 million. The note was due on February 2, 2014 and accrued interest at a rate of 5.5% each four months from October 4, 2013 (with a rate of 2% per month if a default occurred). The note was cancelled as payment for the investor’s purchase of Tranche I Notes in the October 2013 Financing.

	In December 2013, the Company agreed to issue to Temasek $25.0 million of Tranche II Notes for cash. Total purchased approximately $6.0 million of Tranche II Notes through cancellation of the same amount of principal of previously outstanding convertible promissory notes held by Total (in respect of Total’s preexisting contractual right to maintain its pro rata ownership position through such cancellation). Such financing transactions closed in January 2014 (see Note 5, "Debt").

	In December 2013 the Company agreed (i) to exchange the $69.0 million outstanding Total unsecured convertible notes and issue a replacement 1.5% senior secured convertible notes, in principal amounts equal to the principal amount of each cancelled note (see Note 5, "Debt") and (ii) that all notes issued in connection with a third closing under the Total Purchase Agreement will be senior secured convertible notes instead of senior unsecured convertible notes (see Note 5, "Debt").

	As of March 31, 2014 and December 31, 2013, $91.0 million and $89.5 million, respectively, was outstanding under convertible notes with related parties, net of debt discount of $47.4 million and $23.9 million, respectively. For the three months period ending March 31, 2014 and 2013, the Company recorded a loss from extinguishment of debt from the exchange and cancellation of related party convertible notes of $9.4 million, and zero, respectively (see Note 5, "Debt").

	Net Income (Loss) Attributable to Common Stockholders and Net Income (Loss) per Share

	The Company computes net income (loss) per share in accordance with ASC 260, “Earnings per Share.” Basic net income (loss) per share of common stock is computed by dividing the Company’s net income (loss) attributable to Amyris, Inc. common stockholders by the weighted average number of shares of common stock outstanding during the period. Diluted net income (loss) per share of common stock is computed by giving effect to all potentially dilutive securities, including stock options, restricted stock units, common stock warrants, convertible promissory note using the treasury stock method or the as converted method, as applicable. For the three months period ended March 31, 2013, basic net loss per share was the same as diluted net loss per share because the inclusion of all potentially dilutive securities outstanding was anti-dilutive. As such, the numerator and the denominator used in computing both basic and diluted net loss are the same.

	The following table presents the calculation of basic and diluted net loss per share of common stock attributable to Amyris, Inc. common stockholders (in thousands, except share and per share amounts):

	The accompanying interim condensed consolidated financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“GAAP”) and with the instructions for Form 10-Q and Regulation S-X. Accordingly, they do not include all of the information and notes required for complete financial statements. These interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Form 10-K filed with the Securities and Exchange Commission (“SEC”) on April 2, 2014. The unaudited condensed consolidated financial statements include the accounts of the Company and its consolidated subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Principles of Consolidations	'
	Principles of Consolidation

	The Company has interests in joint venture entities that are variable interest entities (“VIEs”). Determining whether to consolidate a variable interest entity requires judgment in assessing (i) whether an entity is a VIE and (ii) if the Company is the entity’s primary beneficiary and thus required to consolidate the entity. To determine if the Company is the primary beneficiary of a VIE, the Company evaluates whether it has (i) the power to direct the activities that most significantly impact the VIE’s economic performance and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. The Company’s evaluation includes identification of significant activities and an assessment of its ability to direct those activities based on governance provisions and arrangements to provide or receive product and process technology, product supply, operations services, equity funding and financing and other applicable agreements and circumstances. The Company’s assessment of whether it is the primary beneficiary of its VIEs requires significant assumptions and judgment.

	The condensed consolidated financial statements of the Company include the accounts of Amyris, Inc., its subsidiaries and two consolidated VIEs with respect to which the Company is considered the primary beneficiary, after elimination of intercompany accounts and transactions. Disclosure regarding the Company’s participation in the VIEs is included in Note 7, "Joint Venture and Noncontrolling Interest."
Use of Estimates	'
	Use of Estimates

	In preparing the unaudited condensed consolidated financial statements, management must make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

	Recent Accounting Pronouncements

	In July 2013, the Financial Accounting Standards Board ("FASB") issued an amended accounting standard update on the financial statement presentation of unrecognized tax benefits. The amended guidance provides that a liability related to an unrecognized tax benefit would be presented as a reduction of a deferred tax asset for a net operating loss carryforward, a similar tax loss or a tax credit carryforward if such settlement is required or expected in the event the uncertain tax position is disallowed. The new guidance became effective for the Company on January 1, 2014 and will be applied prospectively to unrecognized tax benefits that exist at the effective date with retrospective applications permitted. The Company's current presentation of unrecognized tax benefits conforms with the amended guidance. Accordingly, there was no significant impact to the Company resulting from the guidance.
