liability company (“NimbleGen Iceland”; and together with NimbleGen, individually and collectively, “Borrower”), and GENERAL ELECTRIC CAPITAL CORPORATION, a Delaware corporation (together with its successors
and assigns, collectively, “Lender”). 
 RECITALS 
 A. Pursuant to the Amended and Restated Loan and Security Agreement, dated as of December 29, 2006 (as amended, restated, supplemented or
otherwise modified from time to time, the “Loan Agreement”), by and among Borrower and Lender, the parties have established certain financing arrangements that allow Borrower to borrow funds from Lender in accordance with the terms
and conditions set forth in the Loan Agreement. 
 B. Borrower has requested that Lender agree to make certain amendments to the Loan
Documents, and Lender is willing to agree to such requests, in accordance with the terms and conditions set forth below. 
 NOW,
THEREFORE, in consideration of the premises set forth above, the terms and conditions contained in this Amendment, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Lender and Borrower
hereby agree as follows: 
 1. Recitals; Definitions. The foregoing recitals, including all terms defined therein, are
incorporated herein and made a part hereof. All capitalized terms used herein (including, without limitation, in the foregoing recitals) and not defined herein shall have the meanings given to them in the Loan Agreement. 
 2. Amendments to Loan Documents. 
 (a) The following provision is hereby added to the Loan Agreement as Section 9.16(b): 
 “ (b) Any information from
time to time delivered to Lender by Borrower that is identified as confidential and that is not in the public domain shall be held by Lender as confidential, shall be used solely in connection with the Obligations (as they may be increased, amended,
refinanced, renewed or otherwise modified from time to time), the Loan Documents (including without limitation, the Warrant) and services related thereto and the transactions contemplated thereby, and shall not be disclosed by Lender to any other
Person; provided, that Lender may make disclosure of confidential information (i) to its independent accountants and legal counsel (which Persons shall be likewise bound by the provisions of this Section 9.16(b)),
(ii) pursuant to statutory and regulatory requirements or demand by any Governmental Authority, (iii) pursuant to any mandatory court order or subpoena or in connection with any legal process, (iv) pursuant to any written agreement
hereafter made between Lender and Borrower to which such information relates, which agreement permits such disclosure, (v) as necessary or advisable in connection with the exercise of any remedy by Lender under the Loan Documents, (vi) in
accordance with Section 6.11 (vii) consisting of general portfolio information that does not identify Borrower, (vii) that has heretofore been made generally available to the public or is otherwise available to Lender on a
non-confidential basis from a source that is not, to its knowledge, subject to a confidentiality agreement with Borrower, (ix) to any assignee of or participant in any of the Obligations, or to any prospective assignee or participant in any of
the Obligations, provided, that such prospective assignee or participant is subject to an agreement containing provisions substantially the same as those set forth in this Section 9.16(b), and (x) in connection with any
litigation to which Lender or its Affiliates is a party. All financial statements and reports furnished by Borrower to Lender under Section 5.1 hereof shall be deemed confidential and shall not be disclosed by Lender to any other Person
except as provided in this Section 9.16(b). In the event of any conflict between the terms of this Section 9.16(b) and those of any other contractual obligation between Lender and Borrower (whether or not a Loan Document),
the terms of this Section 9.16(b) shall govern. “ 

 (b) Exhibit G-4 of the Loan Agreement is hereby deleted in its entirety and replaced with the Exhibit G-4
attached hereto as Exhibit A. 
 (c) Each of Schedule B-11, Schedule E-25 and Schedule F-34 of the Information Certificate is hereby
deleted in its entirety and replaced with the Schedule B-11, the Schedule E-25 and the Schedule F-34 attached hereto as Exhibit B, Exhibit C and Exhibit D, respectively. 
 3. No Other Amendments. Except for the amendments expressly set forth and referred to in Section 2 above, the Loan Agreement
and all other Loan Documents shall remain unchanged and in full force and effect, and this Amendment shall be limited precisely and expressly as drafted and shall not be construed as a consent to the amendment, restatement, modification,
supplementation or waiver of any other terms or provisions of the Loan Agreement or any other Loan Document. Nothing in this Amendment is intended, or shall be construed, to constitute a novation or an accord and satisfaction of any of
Borrower’s indebtedness under or in connection with the Loan Agreement or any other indebtedness to Lender. 
 4. Confirmation of
Representations and Warranties. 
 Borrower hereby confirms that all of the representations and warranties set forth in Article IV of
the Loan Agreement continue to be true and correct as of the date hereof, except to the extent such representations and warranties by their terms expressly relate only to a prior date (in which case such representations and warranties shall be true
and correct as of such prior date). 
 5. Costs and Expenses. 
 Borrower shall be responsible for the payment of all fees, costs and expenses incurred by Lender in connection with the preparation and negotiation of
this Amendment, including, without limitation, any and all fees and expenses of Lender’s in-house and outside counsel. All fees, costs and expenses shall be due and payable upon demand of Lender, and if not paid promptly upon such demand, all
such fees, costs and expenses shall become part of the Obligations in accordance with Section 2.4 of the Loan Agreement. 
 6.
Reference to the Effect on the Loan Agreement. 
 (a) Upon the effectiveness of this Amendment, each reference in the Loan
Agreement to “this Agreement,” “hereunder,” “hereof,” “herein” or words of similar import shall mean and be a reference to the Loan Agreement as modified by this Amendment. 
 (b) Except as specifically modified above, the Loan Agreement and all other Loan Documents, shall remain in full force and effect, and are hereby
ratified and confirmed. 
 (c) The execution, delivery and effectiveness of this Amendment shall not, except as expressly provided in this
Amendment, operate as a waiver of any right, power or remedy of Lender, nor constitute a waiver of any provision of the Loan Agreement or any other documents, instruments and agreements executed or delivered in connection with the Loan Agreement.

 7. Governing Law. This Amendment shall be governed by and construed in accordance with the laws of the State of New York.

 8. Headings. Section headings in this Amendment are included for convenience of reference only and shall not constitute a
part of this Amendment for any other purpose. 
 9. Counterparts. This Amendment may be executed in counterparts, and such
counterparts taken together shall be deemed to constitute one and the same instrument. Delivery of an executed counterpart of this Amendment by telefacsimile or other electronic method of transmission shall be equally as effective as delivery of an
original executed counterpart of this Amendment. Any party delivering an executed counterpart of this Amendment by telefacsimile or other electronic method of transmission also shall deliver an original executed counterpart of this Amendment but the
failure to deliver an original executed counterpart shall not affect the validity, enforceability or binding effect of this Amendment.

 S-1Commercial Use License Agreement

 Exhibit 10.7 
 NOTE: The information designated by a bracketed asterisk [*] has been omitted pursuant to a request for confidential treatment and has been filed separately with the Securities and Exchange Commission. 
 COMMERCIAL USE LICENSE AGREEMENT 
 between 
 AFFYMETRIX, INC. 
 and 
 NIMBLEGEN SYSTEMS INC. 
 dated 
 September 26, 2006 
 CONFIDENTIAL 

 COMMERCIAL USE LICENSE AGREEMENT 
 This Commercial Use License Agreement (the “Agreement”), effective as of September 26, 2006 (the “Effective
Date”), is between Affymetrix, Inc., a Delaware corporation with offices located at 3420 Central Expressway, Santa Clara, California 95051, hereinafter referred to as “Affymetrix,” and NimbleGen Systems Inc., a Delaware
corporation with offices located at One Science Court, Madison, Wisconsin 53711, hereinafter referred to as “NimbleGen.” 
 RECITALS 
 WHEREAS, NimbleGen desires to obtain a license to Affymetrix Patent Rights, and Affymetrix is willing to grant
such rights on the terms and conditions set forth in this Agreement; 
 NOW, THEREFORE, in consideration of the mutual promises contained
herein and other good and valuable consideration, receipt and sufficiency of which are hereby acknowledged, the Parties hereby agree as follows: 
 1.
DEFINITIONS 
 Capitalized terms used in this Agreement are as defined herein. Except as otherwise specifically stated, all references to
“Section” or “Subsection” are to sections or subsections respectively of this Agreement, and references to a “Section” include subsections of the specified Section. 
 The following terms, as used herein, have the following meanings: 
 1.1 “Affiliate” means, with respect to a given party, any other entity directly or indirectly controlling, controlled by, or under common control with such party. For clarity and without limiting the foregoing,
“Affiliate” with respect to a Party shall mean all present and future companies (other than the Party) whose outstanding stock carrying the right to vote for or appoint directors thereof is more than fifty percent (50%) owned or
Controlled, directly or indirectly, by the Party but only so long as such ownership or control exists. The Parties acknowledge and agree that “Control(led)” or “Controlling” as used in this Agreement in the context
of corporate governance means the power to direct (including through multiple corporate subsidiary tiers) day-to-day operations, management, and policies. Therefore, “Affiliates” of the Parties hereto includes those Affiliates where a
Party has operational control of such Affiliate, but only for so long as such control exists. 
 1.2 “Affymetrix Patent
Rights” means those patent rights arising from claims of all Affymetrix patents and patent applications filed as of the Effective Date as well as any inventions conceived as of the Effective Date, and of all continuations, continuations in
part, divisions, reexaminations and reissues thereof, and of any corresponding foreign patents and patent applications claiming priority thereto, to the extent that such claims read on Licensed Products or Licensed Services in the Licensed Field.

		  		  	NimbleGen Systems, Inc.

 1.3 “Applied Genomics Use,” means all non-research uses other than a Diagnostic Use.
Non-limiting examples of Applied Genomics Uses include forensic testing, paternity testing, agricultural/food testing, and non-human diagnostics and testing. For clarity, research aimed at developing or evaluating such uses is a Research Use and
thus not an Applied Genomics Use. 
 1.4 “Approved Supplier” means an entity that makes Licensed Products for, and sells
Licensed Products directly to, NimbleGen in furtherance of and in accordance with the “have-made” right of Section 2.1.1 under an agreement with NimbleGen requiring (i) that such have-made right is to be exercised solely by the
employees of the Approved Supplier or an Affiliate of the Approved Supplier that it controls at the facilities of the Approved Supplier or such Affiliate and that such agreement may not be assigned or transferred to any other entity; and
(ii) the Approved Supplier may not market or otherwise solicit orders for Licensed Products or Licensed Services from any entity except under license from Affymetrix, and may not accept orders for Licensed Products or Licensed Services from any
entity except under license from Affymetrix. In the event that an Approved Supplier has violated any of the restrictions under (i) or (ii) of this Subsection 1.4, then NimbleGen shall suspend the limited have-made right granted in this
Subsection 1.4 with respect to such Approved Supplier for a cure period of up to sixty (60) days, and failing such cure within such period, shall immediately terminate such have-made right with respect to such Approved Supplier. NimbleGen shall
use commercially reasonable efforts to ascertain whether any such violation has occurred, such as including appropriate reporting and auditing requirements in its relevant contracts with Approved Suppliers. Affymetrix may also notify NimbleGen of
any such violation of which Affymetrix is aware. Notwithstanding any other provision of this Agreement to the contrary, a Prohibited Entity may not be an Approved Supplier unless Affymetrix provides its prior written consent. For clarity, subject
only to the exercise by NimbleGen of the have-made right specified herein with respect to Approved Suppliers, nothing in this Agreement shall be construed as a grant of a license or right under Affymetrix Patent Rights, express or implied, from
Affymetrix directly or indirectly to an Approved Supplier, of any kind including (i) to make, use, offer for sale, or sell arrays, reagents, instruments, software, or any other product or composition of matter, (ii) to provide services, or
(iii) to practice any method or process. Nothing in this Agreement shall be construed to provide Approved Suppliers with any such grants or rights as a third-party beneficiary or under any other theory of law or equity. 
 1.5 “Change of Control” means: 
 1.5.1 any voluntary or involuntary liquidation, dissolution or winding up of the affairs of NimbleGen; or 
 1.5.2 the sale of all
or substantially all of NimbleGen’s assets; or 
 1.5.3 any sale or transfer of the outstanding shares of capital stock of NimbleGen or
the merger or consolidation of NimbleGen with another person or entity (whether in a single transaction or in a coordinated series of transactions), as a result of which any Person (as defined in Sections 13(d)(3) and 14(d)(2) of the Exchange Act as
in effect as of the Effective Date) acquires, 
  

					
	 AFFYMETRIX CONFIDENTIAL
	  	Page 3 of 29	  	CORP
		  		  	NimbleGen Systems, Inc.

 directly or indirectly, beneficial ownership (determined in accordance with Exchange Act Rule 13d-3 as in effect as of
the Effective Date) of more than 50% of the then outstanding shares of common stock of NimbleGen or voting securities representing more than 50% of the combined voting power of NimbleGen’s then outstanding voting securities entitled to vote
generally in the election of directors (or other managing authority) of NimbleGen or the surviving or resulting corporation or acquirer, as the case may be, immediately following such transaction. For clarity and notwithstanding any term or
implication herein to the contrary, no Change of Control under Subsection 1.5.2 or Subsection 1.5.3 shall be deemed to have occurred solely as the result of an acquisition by an entity of assets or outstanding voting securities of NimbleGen where
the owners of such entity, following such acquisition, are substantially identical and hold substantially the same proportional ownership interest and voting control in and of such entity as that held by NimbleGen’s shareholders in and of
NimbleGen immediately prior to such acquisition. 
 1.6 “Current Affiliates” means the following entities that are
Affiliates of NimbleGen as of the Effective Date: NimbleGen Systems of Iceland, LLC, a Delaware limited liability company; and NimbleGen Systems GmbH, a German limited liability company. 
 1.7 “Database” means a collection of data derived from the use of Nucleic Acid Arrays that is transferred to one or more third parties
for the purpose of generating revenue directly from the transfer of such Database, or contract services based on such collection of data. A “Database” does not include data that NimbleGen provides to an End User in the performance of a
Licensed Service, and does not include software that enables the storage, manipulation, or analysis of data. 
 1.8 “Diagnostic
Use” means use in a clinical diagnostic setting where data from an individual sample is given to such individual or the individual’s care giver for the diagnosis or treatment of a medical condition of an individual. For clarity and
without limiting the foregoing, use for any of the following purposes constitutes a Diagnostic Use: (i) use in clinical trials (with the exception of clinical research performed in the development of diagnostic products); (ii) determining
predisposition to a medical condition; (iii) screening (e.g., a pre-natal test for a medical condition of an individual); (iv) diagnosis (e.g., where a patient has presented with symptoms); (v) prognosis; (vi) therapy selection
(e.g., to determine appropriate and safe levels of a prescribed therapeutic); or (vii) monitoring (e.g., to measure the efficacy of a therapeutic). Notwithstanding the foregoing, “Diagnostic Use” includes any use requiring clearance,
approval, or registration with the FDA or any similar regulatory body including any EU Notified Body. 
 1.9
“Distributor” means a distributor, reseller, or other form of dealer who resells Licensed Products and/or Licensed Services for or on behalf of NimbleGen without making any further modification to the package or branding of
the Licensed Product or Licensed Service provided by NimbleGen to Distributor. However, any such entity, or any other entity, is not a Distributor for purposes of this Agreement, and NimbleGen is not licensed to sell to End Users through such an
entity under this Agreement, if at least one of the following (i) through (iv) applies: (i) such entity is a Prohibited Entity; (ii) such entity promotes, distributes, sells, resells, leases, offers for sale, offers for lease, or
otherwise transfers or offers for transfer, any Licensed Product or Licensed Service 
  

					
	 AFFYMETRIX CONFIDENTIAL
	  	Page 4 of 29	  	CORP
		  		  	NimbleGen Systems, Inc.

 (whether by itself or in any manner combined with a device, system, product, or service that is not a Licensed Product or
Licensed Service) under its own name or mark, or under any names or marks other than that of NimbleGen (including by co-branding or by using its or a Third Party’s own name or mark on a device, system, product, or service that is combined with
any Licensed Product or Licensed Service where the sale, lease or transfer of such Licensed Product or Licensed Service is conditioned upon such combination); (iii) such entity adds value of substance or appearance to the Licensed Product or
Licensed Service as, for example and without limitation, by adding, substituting, or altering packaging or documentation; or by combining or transferring a Licensed Product or Licensed Service with any other device, system, product, or service; or
(iv) such entity undertakes research or development activities of its own with respect to Licensed Products or Licensed Services. For clarity, and notwithstanding any term or implication herein to the contrary, the affixing of a
distributor’s identification and/or contact information on the packaging and/or labeling of a Licensed Product or Licensed Service shall not alone disqualify such distributor from being a Distributor hereunder so long as such Licensed Product
or Licensed Service is clearly identifiable as being a product or service, respectively, originating from NimbleGen and not from such distributor. Notwithstanding any term or implication herein to the contrary, NimbleGen’s Japanese distributor,
GeneFrontier Corporation, may be a Distributor for purposes hereof with respect to the following transactions or activities in Japan only, even if GeneFrontier Corporation (a) promotes, distributes, sells, resells, leases, offers for sale,
offers for lease, or otherwise transfers or offers for transfer Licensed Products or Licensed Services under the name “Nandemo Array,” in Japan (b) combines or transfers Licensed Services with software that adds value to the Licensed
Products or Licensed Services in Japan, and/or (c) conducts research activities with respect to Licensed Services in Japan, including in collaboration with others, for Japanese government-sponsored institutions. The allowances provided to
GeneFrontier Corporation in the preceding sentence are personal to GeneFrontier Corporation (and do not, for example, extend to any Affiliate of GeneFrontier Corporation) and do not apply to, and may not be assumed by, any other entity by
implication or otherwise. In the case that an existing Distributor falls within one of the limitations listed in this Subsection 1.9 at any time during the Term, a wind-down period of up to ninety (90) days shall be allowed during which time
NimbleGen may, at its sole discretion, make other distribution arrangements or decide to discontinue the use of such Distributor for Licensed Products or Licensed Services. 
 1.10 “End User” means a third party that receives Licensed Products or Licensed Services within the Licensed Field. For clarity, an End
User may include core laboratories or other analytical reference laboratories, or other types of service providers, that analyze biological samples and provide the results of those analyses to the person who supplied the biological samples for
analysis. 
 1.11 “Feature” means a contiguous region of the substrate of a Nucleic Acid Array on which it is intended to
impose the same chemical synthesis process.

	  	Page 5 of 29	  	CORP
		  		  	NimbleGen Systems, Inc.

 1.12 “Functionally Equivalent Device” means a computer-controlled device for
mirror-modulated, light-directed synthesis. 
 1.13 “Licensed Field” means research use only. For clarity and without
limiting the foregoing, the Licensed Field shall not include (i) sale, license, or other transfer of a Database, (ii) any Diagnostic Use, or (iii) any Applied Genomics Use. 
 1.14 “Licensed Products” means Nucleic Acid Arrays, Nucleic Acid Array Reagents and Assays, NimbleGen Instruments, and NimbleGen
Software, all to the extent covered by a claim included within the Affymetrix Patent Rights. NimbleGen Array Makers are not included in Licensed Products. 
 1.15 “Licensed Services” means commercial services provided directly by NimbleGen or a Distributor to an End User for a fee or any other type of consideration, recognition, payment in kind, or quid
pro quo arrangement, wherein NimbleGen uses Licensed Products to process a biological sample at its own facilities on behalf of the End User, and NimbleGen or a Distributor returns the results of the processing (i.e., data only) directly and solely
to the End User. 
 1.16 “Maximum Annual Licensed Number of Features” means the number One Trillion, Six Hundred Billion
(1.6 E12, or 1,600,000,000,000), or such greater number as may be determined in accordance with Subsection 5.2. 
 1.17 “Net
Sales” means [*]. In the event Licensed Products or Licensed Services are sold, performed, or otherwise transferred in other than an arm’s-length transaction to an End User or Distributor with which NimbleGen has any agreement,
understanding, or arrangement without which prices paid by such End User or third party would be higher than the gross amounts reported by NimbleGen, or if such agreement, understanding, or arrangement results in extending to such End User or third
party lower prices for Licensed Products or Licensed Services than those charged to outside purchasers buying similar products or services under similar conditions, then, in any such event, the royalties to be paid hereunder in respect to such
Licensed Products or Licensed Services shall be calculated on the greater of: (i) the gross amounts that would have been generated by the same transaction had NimbleGen sold such Licensed Products or Licensed Services to an outside purchaser in
an arm’s-length transaction; or (ii) the gross amount at which such Licensed Products or Licensed Services are so resold (if 
  

					
	 AFFYMETRIX CONFIDENTIAL
	  	Page 6 of 29	  	CORP
		  		  	NimbleGen Systems, Inc.

 applicable). Notwithstanding the foregoing, Net Sales to a Distributor shall be deemed to be royalty bearing at an amount
no less than sixty percent (60%) of the average retail selling price charged by NimbleGen for the same or similar Licensed Products or Licensed Services in similar circumstances to End Users over the preceding twelve month period. It is the
Parties’ intention in all transactions involving Licensed Products and Licensed Services that Affymetrix shall receive a royalty not less than that which would have been generated in an arm’s-length transaction. For the avoidance of doubt,
NimbleGen shall at all times act in good faith (including the use of generally accepted accounting principles, consistently applied) and NimbleGen shall not intentionally or knowingly inappropriately or inaccurately apportion amounts invoiced or
received for the purpose or effect of circumventing or depriving Affymetrix of the benefit of the definition of Net Sales or its calculation hereunder. 
 1.17.1 If one or more Licensed Product(s) or Licensed Service(s) is sold or otherwise transferred by NimbleGen in combination with other products or services (any such combination hereafter referred to as a
“Combination”), the Net Sales of each Licensed Product or Licensed Service included in the Combination shall be the greatest of the following: 
 1.17.1.1 the greatest list price of the Licensed Product or Licensed Service; 
 1.17.1.2 the aggregate
selling price of the Combination multiplied by a fraction, the numerator of which shall be the standard cost for such Licensed Product or Licensed Service and the denominator of which shall be the standard cost for the Combination as determined by
U.S. generally accepted accounting principles, consistently applied; or 
 1.17.1.3 the standard cost of the Licensed Service, multiplied by
150%. 
 1.17.2 If Licensed Products are provided to, or if Licensed Services are performed for, unaffiliated End Users for non-cash
consideration, free of charge, or where no invoice is generated, Net Sales of such Licensed Products or Licensed Services shall be valued by determining the average selling price of similar Licensed Products or Licensed Services performed for
unaffiliated End Users for cash. 
 1.18 “NimbleGen Array Maker” means an instrument incorporating a TI DLP or Functionally
Equivalent Device, developed and employed by NimbleGen for the mirror-modulated, light-directed, synthesis of Nucleic Acid Arrays without any use of masks. 
 1.19 “NimbleGen Hybridizers” means systems or instruments and related computer hardware and associated loading instruments, if any, designed and/or configured to hybridize or incubate Nucleic Acid
Arrays. 
 1.20 “NimbleGen Instruments” means NimbleGen Hybridizers and NimbleGen Scanners; and also means any other
instrument designed and/or configured for use with Nucleic Acid Arrays, all to the extent covered by a claim included within the Affymetrix Patent Rights, provided, however, that a NimbleGen Array Maker is not a NimbleGen Instrument.

applications filed as of the Effective Date that are: (i) assigned to NimbleGen or its Affiliate, (ii) under an obligation to be assigned to NimbleGen or its Affiliate, or (iii) with respect to which NimbleGen or its Affiliate has a
right to grant the covenant specified in Section 2.3 below. 
 1.22 “NimbleGen Scanners” means systems or instruments
designed and/or configured to scan signals from Nucleic Acid Arrays including associated computer hardware and associated loading instruments, if any, designed and/or configured to load or transfer the Nucleic Acid Microarrays for scanning.
“Scan” in this context means the operations of instruments, commonly referred to as scanners or readers, involved in reading, imaging, and/or otherwise detecting emissions or other radiations or signals. For clarity, NimbleGen
Scanners do not include any system or instrument designed and/or configured to scan arrays made by or for Affymetrix using photolithographic synthesis using masks. 
 1.23 “NimbleGen Software” means the following types of software to the extent applied to Nucleic Acid Arrays in the Licensed Field: (i) array-design software, (ii) software for image
extraction and preliminary analysis (e.g., accepting an image file and an array description file, locating a feature grid, quantifying individual features, and generating values for genetic loci represented on a Nucleic Acid Array), and
(iii) software for analyzing data or annotating data points with biological information, all to the extent covered by a claim included within the Affymetrix Patent Rights. 
 1.24 “Nucleic Acid Array” means an array of DNA oligonucleotide probes synthesized by NimbleGen at defined locations on a single

extent covered by a claim included within the Affymetrix Patent Rights. 
 1.26 “Party/ies” means Affymetrix or NimbleGen,
or both together. 
 1.27 “Prohibited Entity” means and includes, with respect to a particular transaction/event and as of
the time of that transaction/event, any entity that: (i) is directly or indirectly involved as an adverse party or by assisting an adverse party in any existing litigation, arbitration, opposition, or other dispute-resolution proceeding in
which Affymetrix is an adverse party involving patent rights or licenses; or (ii) either directly or indirectly controls, or directly or indirectly is engaged in, any business that develops, manufactures, markets or sells a microarray that is
not licensed by Affymetrix and, as determined by Affymetrix in its sole discretion, infringes any Affymetrix patent; or (iii) sells, or otherwise transfers more than one thousand (1,000) microarrays per year that are not licensed by
Affymetrix. Notwithstanding the foregoing, any investment fund the principal business purpose of which is to invest in companies and that is not owned or otherwise controlled, directly or indirectly, by a Prohibited Entity, is not a Prohibited
Entity.

expressly provided in Section 10.7, below), non-sublicensable, non-exclusive, royalty-bearing license for the Term and within the Territory under the Affymetrix Patent Rights. The license is to: 
 2.1.1 Make Licensed Products and have Licensed Products made by an Approved Supplier (provided, however, that the total number of Features on all Nucleic
Acid Arrays made by all of NimbleGen, Current Affiliates, and all Approved Suppliers in any calendar year during the Term does not exceed the Maximum Annual Licensed Number of Features), and make NimbleGen Array Makers but only for the internal use
of NimbleGen and Current Affiliates and not for use by, or import, sale, or any other transfer to, any other entity; 
 2.1.2 Use Licensed
Products in the Licensed Field; and 
 2.1.3 Import, sell and offer for sale directly to End Users, and have-sold through a Distributor
directly to End Users, Licensed Products in the Licensed Field and Licensed Services in the Licensed Field. 
 2.2 Limitations on
Grant: For clarity, and notwithstanding any other provision of this Agreement to the contrary, the grant of Section 2.1.1 is limited to making only the Maximum Annual Licensed Number of Features in any calendar year during the Term, and
no right or license is granted or may be implied under this Agreement for NimbleGen, its Current Affiliates, Approved Suppliers or any other entity to make any additional Nucleic Acid Arrays after such limitation has been reached in a calendar year.
In calculating the Maximum Annual Licensed Number of Features, all Features made by NimbleGen, Current Affiliates, any Approved Supplier, or any combination thereof, shall be included so that the combined total of all such Features shall not exceed
the Maximum Annual Licensed Number of Features. No carry-over or credit of numbers of Features is allowed from one calendar year to another. For further clarity, no right or license is granted or may be implied under this agreement, directly or

  

					
	 AFFYMETRIX CONFIDENTIAL

 6.2 Currency. All payments by NimbleGen hereunder shall be made in United States Dollars in
the form of a check sent to Affymetrix as provided in Article 9, or by wire transfer to a bank designated by Affymetrix, and shall be made in the full amounts as herein specified; provided that deduction may be made from such payments by
NimbleGen for income or similar taxes actually levied or assessed upon such payments by any foreign government which are lawfully required to be withheld and paid by NimbleGen and which are paid by NimbleGen on behalf of Affymetrix to the proper
taxing authority. Proof of payment shall promptly be secured and sent to Affymetrix as evidence of such payment in such form as required by the tax authorities having jurisdiction over NimbleGen. Affymetrix shall have the right at any time or from
time to time to contest by appropriate proceedings the validity or amount of any such income tax withheld. If so requested by Affymetrix, NimbleGen will make such payments under protest, and, on behalf and at the expense of Affymetrix, take such
other action and render all reasonable assistance that may be required by Affymetrix in the prosecution of any such proceedings. NimbleGen will obtain and forward to Affymetrix tax credit receipts or vouchers for all income taxes thus withheld and
paid by NimbleGen. As used in this paragraph, “income tax” shall mean a tax on income imposed by a country other than the United States of America or by any possession or territory of the United States of America, on account of the receipt

Affymetrix of such delinquency, then Affymetrix may, at its sole option, terminate this Agreement on the fifteenth (15th) business day after written notice is given to NimbleGen by certified mail, return receipt requested that it intends to
terminate this Agreement. All late payments shall bear interest at the rate of one percent (1.0 %) per month or the prime rate as published in The Wall Street Journal on the first business day of the month in which the payment should have been made,
whichever is greater, unless the maximum amount allowed by law is lower, in which case all late payments shall bear interest at the maximum permitted rate. 
 6.4 Bookkeeping. In keeping with established bookkeeping and accounting practices, NimbleGen shall maintain, for a period of four (4) years following the end of the calendar year in which any
royalties are payable, appropriate books and records fully adequate to show the Net Sales and the full amount of royalty payable under this Agreement, including, but not limited to, books, records and electronic files showing each sale, lease, or
other transfer of Licensed Products or Licensed Services, the net invoice price for that sale, lease, or other transfer, as appropriate. 
 6.5 Audit. Affymetrix shall have the right, but not to exceed once per calendar year, during regular business hours and upon ten (10) days’ notice, to have a nationally recognized auditing firm make such examination
of NimbleGen’s records and books of

		  		  	NimbleGen Systems, Inc.

 account that are then required under Subsection 6.4 to be maintained with respect to any calendar year as is necessary to
verify the Net Sales in such calendar year and the royalties payable with respect thereto. In the event that such examination reveals a discrepancy between the royalties payable hereunder and the royalties actually paid, all such additional
royalties, together with interest from the date when such additional royalties would have been due, shall be paid to Affymetrix within thirty (30) days of written notice from Affymetrix of such discrepancy. Any such audit shall be at
Affymetrix’ sole expense; provided that in the event that a deficiency of more than five percent (5%) is discovered, the audit shall be at NimbleGen’s expense. Books and records pertaining to any given calendar year may be
examined by the auditing firm only once unless a discrepancy of more than five percent (5%) is discovered. The auditing firm conducting the examination shall be under appropriate obligations of confidentiality to all Parties such that,
(a) if no discrepancy is found between royalties payable and actually paid for a given calendar year, the auditing firm shall report that and nothing else to Affymetrix, (b) if a discrepancy in favor of Affymetrix is found between
royalties payable and actually paid, the auditing firm shall report the amount of the discrepancy and only those particulars necessary for inclusion in the notice previously mentioned in this Section 6, if a discrepancy in favor of NimbleGen is
found between royalties payable and actually paid, the auditing firm shall report the amount of the discrepancy and only those particulars necessary for the understanding of Affymetrix and NimbleGen of the nature of the overpayment, and Affymetrix
shall reimburse NimbleGen within thirty (30) days of the date of the report of the auditing firm, (c) in no event shall the auditing firm reveal to any Party any information it may gain during the course of the examination other than as
previously stated, and (d) in no event shall the auditing firm reveal to any third party any information it may gain during the course of the examination.

 (a) The Parties agree to jointly draft and issue, in the name of one or both parties, a mutually acceptable press release within thirty (30) days
after the Effective Date. Neither Party shall issue any such release without prior written consent of the other. Any information included in a mutually accepted press release is deemed after such release not to be information subject to the
provisions of Section 10.2. 
 (b) Subject to the following conditions, either Party may disclose the terms and conditions of this
Agreement to any bona fide potential acquirer of or potential party to an acquisition by or joint venture or strategic license arrangement with, or potential investor in or lender to, the Party disclosing the information with respect to a
transaction as to which the terms of this Agreement are reasonably material, and that acquirer’s, party’s, investor’s, or lender’s legal counsel, financial advisor and accounting firm (all of the third parties specified in this
sentence are hereafter referred to collectively as the “Recipients”). The conditions under which disclosure may be made are: 
 (i)
the non-disclosing Party may request, and the disclosing Party shall implement, redactions to the Agreement that are reasonably not material to the disclosure; 
 (ii) prior to the disclosure, each Recipient shall execute a reasonable and customary confidentiality agreement, on behalf of itself and its representatives, agreeing to maintain the confidential nature of the
disclosure in perpetuity and to utilize the information solely for purposes of internal diligence with respect to the proposed transaction; and 
 (iii) the Recipients shall have the right to review the Agreement in person at premises under the control of the disclosing Party but will not be provided with or permitted to make a copy or written record of the Agreement or excerpts
thereof for removal from such premises (either electronically or via photocopier, telecopy, or in any other manner). 
 (c) Either Party may
disclose this Agreement to its legal counsel, financial advisors and its auditors, provided that such counsel and auditors are advised of the confidential nature of this Agreement prior to such disclosure. 
 10.3 Bankruptcy Code Considerations. The Parties agree that this Agreement is an “executory contract” (involving continuing
executory obligations of Affymetrix and NimbleGen to provide licenses of intellectual property and continuing executory obligations of NimbleGen to pay royalties hereunder), under which each Party is a “licensor of a right to intellectual
property”, and that this Agreement is governed under 11 U.S.C. § 365(n) of the United States Bankruptcy Code (“Bankruptcy Code”).

 10.4 Binding Agreement. This Agreement shall not be binding upon the Parties until it has
been signed herein below by or on behalf of each Party, in which event it shall be effective as of the Effective Date. 
 10.5
Equitable Relief. The Parties acknowledge that damages would be an inadequate remedy for any material breach of the confidentiality provisions of this Agreement. Therefore, each Party agrees that the confidentiality obligations
hereunder may be specifically enforceable and that each Party shall be entitled to an injunction, restraining order or other equitable relief from any court of competent jurisdiction, restraining the other Party from committing any such violations
of the provisions of this Agreement. 
 10.6 Severability. If any provision in any Article of this Agreement is found by
competent authority to be invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of such Article in every other respect and of the remainder of this Agreement shall continue in effect so long as
the Agreement still expresses the intent of the Parties. In such case, the invalid/illegal/unenforceable provision shall be replaced by an appropriate provision, which to the extent legally possible, comes closest to the Parties’ intent of what
the Parties would have agreed on, had they been aware of the invalidity/illegality/ unenforceability, in order to meet the spirit and purpose of this Agreement. However, if the intent of the Parties cannot be preserved, this Agreement shall be
terminable by the Party in whose favor the invalid/illegal/unenforceable provision runs. 
 10.7 Assignment. 
 10.7.1 The rights and license granted by Affymetrix in this Agreement, including without limitation the patent license rights granted to NimbleGen and its
Current Affiliates under Article 2 and related provisions (“Patent License”) are personal to NimbleGen and its Current Affiliates (and do not, for example, extend to any other NimbleGen Affiliate). Neither such rights and license,
nor this Agreement, are assignable or otherwise transferable directly, by operation of law, or otherwise, except with the prior written consent of Affymetrix. Such prior written consent shall be deemed to have been given as to an assignee proposed
by NimbleGen provided that such assignee, on the date that the assignment becomes effective, is licensed by Affymetrix to make, use, and sell arrays of nucleic acids in the Licensed Field. Notwithstanding any other provision of this Agreement to the
contrary, such proposed assignee that is so licensed by Affymetrix shall not be considered a Prohibited Entity. Either NimbleGen or the assignee consented to or deemed to have been consented to by Affymetrix shall pay to Affymetrix, as a condition
precedent to such consent, an Assignment Fee as provided in Subsection 5.3. The assignment shall provide that it does not become effective unless and until the Assignment Fee and any unpaid fees or royalties as provided in this Agreement that are
past due have been paid in full. Notwithstanding any other provision of this Agreement, any purported assignment or transfer of the Agreement or the Patent License or other rights granted under the Agreement, except with the prior written consent of
Affymetrix, shall be null and void. In Exhibit C, Affymetrix hereby provides a mechanism to allow NimbleGen to ask a potential acquiring entity whether they are licensed to Affymetrix Patent Rights as it may be relevant under this Agreement. The
mechanism is provided so that the entity is released from any potential duty of confidentiality they may have to Affymetrix under their own license. Exhibit C is a model letter that can be used by NimbleGen to be provided to the entity.

 10.7.2 Except with the prior written consent of Affymetrix, the Patent License shall be terminable by
written notice by and at the discretion of Affymetrix upon (i) the acquisition by NimbleGen or any NimbleGen Affiliate, by merger, acquisition of assets or otherwise, of a direct or indirect Controlling interest in any Prohibited Entity ; or
(ii) the acquisition by any Prohibited Entity, by merger, acquisition of assets or otherwise, of a direct or indirect Controlling interest in NimbleGen or any NimbleGen Affiliate. 
 10.7.3 Except with the prior written consent of Affymetrix, and independently of whether any Change of Control has occurred, the Patent License shall be
terminable by written notice by and at the discretion of Affymetrix upon any transaction or event or series of transactions or events –including without limitation any sale or transfer of the outstanding shares of capital stock of NimbleGen or
the merger or consolidation of NimbleGen with another person or entity – as a result of which one or more Prohibited Entities acting in concert hold in aggregate, directly or indirectly, beneficial ownership (determined in accordance with
Exchange Act Rule 13d-3 as in effect as of the Effective Date) of more than fifty percent (50%) of the then outstanding shares of common stock of NimbleGen or voting securities representing more than fifty percent (50%) of the combined
voting power of NimbleGen’s then outstanding voting securities entitled to vote generally in the election of directors (or other managing authority) of NimbleGen or the surviving or resulting corporation or acquirer, as the case may be,
immediately following such transaction or event. 
 10.7.4 For clarity and notwithstanding any term or implication herein to the contrary,
(i) the prior written consent of Affymetrix shall not be required under Subsection 10.7.1 (and no Assignment Fee shall be payable hereunder) in the case of the assignment or other transfer directly, by operation of law, or otherwise, of the
rights and license granted by Affymetrix in this Agreement to an entity whose owners, following such assignment or other transfer, are virtually identical and hold virtually the same proportional ownership interest and voting control in and of such
entity as that held by NimbleGen’s shareholders in and of NimbleGen immediately prior to such assignment or other transfer, (ii) the Patent License shall not be terminable under Subsection 10.7.2 in the case of a transaction whereupon the
following person becomes an entity that directly or indirectly Controls NimbleGen, and, with respect to any particular transaction, a “Prohibited Entity” shall not mean or include any such person described as follows: an entity whose
owners, following such transaction, are virtually identical and hold virtually the same proportional ownership interest and voting control in and of such entity as that held by NimbleGen’s shareholders in and of NimbleGen immediately prior to
such transaction. 
 10.8 Successors and Assigns. The provisions of this Agreement shall be binding upon and inure to the
benefit of the Parties and their permitted successors and assigns. 
 10.9 Amendments and Waivers. Any provision of this
Agreement may be amended or waived if, but only if, such amendment or waiver is in writing and is signed, in the case of an amendment, by each Party to this Agreement, or in the case of a waiver, by

 the Party against whom the waiver is to be effective. No failure or delay by any Party in exercising any right, power or
privilege hereunder shall operate as a waiver thereof nor shall any single or partial exercise thereof preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein provided
shall be cumulative and not exclusive of any rights or remedies provided by law. 
 10.10 Expenses. Except as otherwise
provided herein, all costs and expenses incurred in connection with this Agreement shall be paid by the Party incurring such cost or expense. 
 10.11 Governing Law. This Agreement shall be governed by and construed under the laws of the State of Delaware without regard to conflicts of laws provisions thereof that would require the application of the law of any other
jurisdiction, and without regard to the United Nations Convention on Contracts for the International Sale of Goods. Affymetrix reserves the right to bring any action relating to infringement of the Affymetrix Patent Rights in any United States
District Court, and NimbleGen hereby irrevocably consents to the jurisdiction of such courts (and of the appropriate appellate courts therefrom) and irrevocably waives, to the fullest extent permitted by law, any objection that it may now or
hereafter have to the laying of the venue of any such action in any such court or that any such action which is brought in any such court has been brought in an inconvenient forum. Any other dispute, claim or controversy arising out of or relating
to this Agreement or the breach, termination, enforcement, interpretation or validity hereof or thereof, including the determination of the scope or applicability of this Agreement to arbitrate, shall be determined by final and binding arbitration
in the San Francisco, California Bay Area if NimbleGen initiates the arbitration, and in Chicago, Illinois if Affymetrix initiates the arbitration (except for an action for interim equitable relief otherwise permitted under this Agreement and/or
unless otherwise agreed by the Parties), before a sole arbitrator, in accordance with the laws of the State of California for agreements made in and to be performed in that State. The arbitration shall be administered by JAMS (or its successor)
pursuant to its Comprehensive Arbitration Rules and Procedures; provided, however, if the Parties mutually elect, the arbitration can be administered by JAMS pursuant to its Streamlined Arbitration Rules and Procedures instead of its Comprehensive
Arbitration Rules and Procedures. The arbitrator’s decision shall be reduced to writing, signed by the arbitrator, and mailed to each of the Parties and their legal counsel. All decisions of the arbitrator shall be final, binding and conclusive
on the Parties. The arbitrator or a court of appropriate jurisdiction may issue a writ of execution to enforce the arbitrator’s judgment. Judgment may be entered upon such a decision in accordance with applicable law in any court having
jurisdiction thereof. The Parties will pay their own costs (including, without limitation, attorneys fees) and expenses in connection with such arbitration. Notwithstanding the foregoing, the Parties acknowledge that each Party’s performance
under this Agreement is unique and may not be easily or readily performed by another party and hereby agree that specific performance may be considered by the arbitrator as a resolution to any dispute. 
 10.12 WAIVER OF JURY TRIAL. EACH OF THE PARTIES HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

Agreement is intended to confer upon any person other than the Parties any rights or remedies hereunder.

 Exhibit A – Exemplary, Non-binding Term Sheet 
 Expansion of Commercial Use License 
 from
Affymetrix, Inc. to NimbleGen Effective – September 26, 2006 
 (“the Research Agreement”) 
 This term sheet shall not create any legally binding obligation of the parties and neither party will be legally bound unless and until the parties have entered into
mutually acceptable, finally written, definitive agreements containing appropriate terms and conditions satisfactory to both parties. Other than the confidentiality provisions relating hereto, no past or future action, course of conduct, or failure
to act relating to the proposed transaction or negotiation of the terms thereof or any definitive agreement will give rise to, or serve as a basis for any obligation or other liability on the part of either of the parties. 
 Affymetrix proposes to expand the definition of Licensed Field as specified in the Research Agreement, subject to agreement on changes to other terms or additions of new
terms including (but expressly not limited to) the following: 
  

			
	Licensed Field	  	 •      The Licensed Field is expanded to include Diagnostic Use. For
clarity, the Licensed Field does not include any Applied Genomics Use.
  
 •     “Applied Genomics Use,” means all non-research uses other than a Diagnostic Use. Non-limiting examples of Applied Genomics Uses include forensic testing, paternity
testing, agricultural/food testing, and non-human diagnostics and testing. For clarity, research aimed at developing or evaluating such uses is a Research Use and thus not an Applied Genomics Use.
  
 •     “Diagnostic
Use” means use in a clinical setting where data from an individual human sample is given to such individual or the individual’s care giver for the purposes of screening, determining predisposition, diagnosis, classification, determining
prognosis, determining drug efficacy or safety, monitoring therapy, or any other use requiring clearance, approval, or registration with the FDA or any similar regulatory body including any EU Notified Body.

		
	Additional Up-Front and Past-Due Fees for Addition of Dx Field	  	Two plans for payment of Up-Front and Past-due Fees are proposed for inclusion in the Agreement. Plan #1 involves payment of the Fees over a period of 6 years. Plan #2 involves accelerated
payment of the Fees over a period of 3 years. NimbleGen may elect to include in the Agreement either Plan #1 or Plan #2. Fees are payable annually in advance and are not creditable against royalties or any other amounts payable under the
Agreement.

  

													
	 Plan #1 (in $M):
	  	Yr1	  	Yr2	  	Yr3	  	Yr4	  	Yr5	  	Yr6
	 Fees
	  	3.5	  	5.0	  	6.5	  	8	  	8	  	8
							
	 Plan #2 (in $M):
	  	Yr1	  	Yr2	  	Yr3	  	Yr4	  	Yr5	  	Yr6
	 Fees
	  	11.0	  	13.0	  	0	  	0	  	0	  	0

		  		  	NimbleGen Systems, Inc.

															
	Additional Assignment Fee for Addition of Dx Field	  	An Assignment Fee, if there is mutual agreement that assignments shall be permitted, shall be based on the market capitalization of the proposed assignee (including any Affiliate
of the assignee) at the time of execution of the proposed assignment as follows:
						
		  	Market Cap	  	< $	1B	  	$	1B-$3B	  	$	3B-$6B	  	>$	6B
						
		  	Assignment Fee	  	$	2.5M	  	$	7.5M	  	$	12.5M	  	$	18.75M
		
	Additional Annual Minimum Royalty for Addition of Dx Field	  	$1M per year, one-half payable in advance and the remainder payable in arrears, fully creditable for the applicable calendar year only

 Terms of this proposal expire April 2, 2007

 Exhibit C – Model Letter 
 To Whom it may concern: 
 Affymetrix and NimbleGen have an Agreement regarding a patent license to Affymetrix patents and
under certain circumstances it is relevant whether a potential acquiring entity is a licensee to the Affymetrix patents. However, in other agreements between Affymetrix and licensees, there is a duty of confidentiality that protects the existence of
any license. Therefore, Affymetrix hereby consents in advance to the disclosure of the existence of an Affymetrix patent license by the potential acquiring entity for the limited purpose of allowing the entity to inform NimbleGen if they are a
current licensee to the Affymetrix patents. Both NimbleGen and the disclosing entity agree that any such disclosure under this letter shall be kept confidential.
