each technician, to assist Fluidigm solely with completion of the work for Fluidigm Collaboration Milestone 5 as amended herein, unless otherwise agreed to in writing by the parties. In addition, Fluidigm agrees to commit no fewer than
[***] Fluidigm Full Time Employees (“FTEs”) in order to achieve the scopes of work set forth under Fluidigm Collaboration Milestone 5 and Fluidigm Collaboration Milestone 6 as amended herein.

  

	 	b.	 In addition to the clinical samples (with follow up) that Novartis has already paid for and provided to Fluidigm (receipt of which is acknowledged

	 	[***]	Information has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted

 CONFIDENTIAL TREATMENT REQUESTED BY FLUIDIGM CORPORATION 

 

	 	shall provide up to [***] additional clinical samples (with follow up) processed (DNA extracts and QC tests applied) if needed, prior to the initiation of the [***]
that is part of Fluidigm Collaboration Milestone 6 for use in the [***] scope of work. The decision to provide such additional samples shall reside with the JSC. If the JSC decides it is necessary that such samples are to be provided to
Fluidigm, then those samples shall be provided by Novartis to Fluidigm no later than [***]. If those samples are not provided by [***], then Fluidigm may process samples previously supplied by Novartis by the then most current extraction method and
QC tests recommended by the JSC and must then process all remaining samples necessary to comprise the [***] samples in the same and consistent manner. (The best QC assay will be determined within the JSC as agreed to by both companies and is
tentatively scheduled to be decided by [***].) 

  

	 	c.	Fluidigm agrees to use diligent efforts to complete the six (6) Phase 1 related Fluidigm Collaboration Milestones, as amended herein, and deliver the
Final Report for all Phase 1 activities by no later than end of business, [***]. 

  

	 	d.	Contingent upon Fluidigm meeting the [***] deadline immediately set forth above, Novartis shall thereafter have up through the end of business on [***] (“Reduced
Option Term”) to exercise its License Option pursuant to Article 5 of the Agreement. Fluidigm’s commitment to meet such [***] deadline is a condition precedent to Novartis’ Reduced Option Term. Otherwise, failure to meet such
condition precedent shall automatically cause reversion of Novartis’ rights to the original ninety (90) day Option Term under Section 5.2 of the Agreement. 

 

	 	5.	In consideration of the extended exclusivity period and amendments set forth herein, Novartis shall pay to Fluidigm a non-refundable amount of [***] dollars (USD
$[***]) within [***] days from receipt of an invoice from Fluidigm. 

  

	 	6.	All of the other terms and conditions of the Agreement shall continue in full force and effect. This Amendment #1, together with the Agreement, constitute the
entire agreement between the parties hereto regarding the subject matter hereof and supersedes any prior and/or contemporaneous agreement(s), understanding(s) and/or negotiations(s). 

IN WITNESS WHEREOF, the parties hereto hereby execute this Amendment #1as of the date set forth above.

Section 4.02 Authorization; Enforceability. The Transactions are within each Credit Party’s corporate,
limited liability company or partnership powers and have been duly authorized by all necessary corporate, limited liability company or partnership and, if required, stockholder action. This Agreement and each of the Loan Documents to which a Credit
Party is party have been duly executed and delivered by such Credit Party and constitutes a legal, valid and binding obligation of such Credit Party, enforceable in accordance with its terms, subject to applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting creditors’ rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law. 

1.3 Financial Covenants. Clause (b) of Section 7.11 of the Credit Agreement shall be and it hereby is amended and
restated in its entirety to read as follows: 
 (b) Leverage Ratio. The Borrower will not permit the

each Lender shall be as set forth on Schedule 2.01 of this Amendment. Each Lender hereby consents to the Commitments set forth on Schedule 2.01 of this Amendment. The reallocation of the Aggregate Commitment among the Lenders,

Assumption attached as Exhibit A to the Credit Agreement as if the Lenders, including the Departing Lender, had executed an Assignment and Assumption with respect to such reallocation. The Administrative Agent hereby waives the $3,500
processing and recordation fee set forth in Section 11.04(b)(ii)(C) of the Credit Agreement with respect to the assignments and reallocations contemplated by this Section 3. The increase in each Increasing Lender’s
Commitment shall be deemed to have been consummated pursuant to the terms of the Lender Certificate attached as Exhibit F to the Credit Agreement as if such Increasing Lender had executed a Lender Certificate with respect to such

  
 Third Amendment to Credit
Agreement – Page 3 

 
increase. To the extent requested by any Lender, including the Departing Lender, and in accordance with Section 2.15 of the Credit Agreement, the Borrower shall pay to such Lender,
within the time period prescribed by Section 2.17 of the Credit Agreement, any amounts required to be paid by the Borrower under Section 2.17 of the Credit Agreement in the event the payment of any principal of any Eurodollar
Loan or the conversion of any Eurodollar Loan other than on the last day of an Interest Period applicable thereto is required in connection with the reallocation contemplated by this Section 3.

written opinion (addressed to the Administrative Agent and the Lenders and dated as of the effective date of this Amendment) of Haynes and Boone, L.L.P., counsel for the Credit Parties, and covering such other matters relating to the Credit Parties

 4.5 Certificates. The Administrative Agent
shall have received such documents and certificates as the Administrative Agent or its counsel may reasonably request relating to the organization, existence and good standing of each Credit Party, the authorization of this Amendment and the
transactions contemplated hereby and any other legal matters relating to the Credit Parties, this Amendment or the transactions contemplated hereby, all in form and substance satisfactory to the Administrative Agent and its counsel. 

4.6 Other Documents. The Administrative Agent shall have received such other instruments and documents incidental and appropriate
to the transaction provided for herein as the Administrative Agent or its special counsel may reasonably request, and all such documents shall be in form and substance satisfactory to the Administrative Agent. 

SECTION 5. Representations and Warranties of Borrower. To induce the Lenders to enter into this Amendment, each Credit Party hereby
represents and warrants to the Lenders as follows: 
 5.1 Reaffirmation of Representations and Warranties/Further
Assurances. After giving effect to the amendments herein, each representation and warranty of such Credit Party contained in the Credit Agreement or in any other Loan Document is true and correct in all material respects on the date hereof

general application.

hereof and immediately after giving effect to the increase in the Aggregate Commitment contained in Section 3 of this Amendment and any Borrowing made on such date, the Borrower is in pro forma compliance with the financial covenants set
forth in Section 7.11 of the Credit Agreement as of the last day of the most recently ended fiscal quarter for which the financial statements and compliance certificate required under Section 6.01 of the Credit Agreement have been
