Restated Revolving Credit and Security Agreement dated as of August 6, 2010, Amendment No. 2 to Amended and Restated Revolving Credit and Security Agreement dated as of March 2, 2011, and Amendment No. 3 to Amended and Restated
Revolving Credit and Security Agreement dated as of March 31, 2011 (as amended, restated, supplemented or otherwise modified from time to time, the “Loan Agreement”) pursuant to which Agent and Lenders provide Borrowers
with certain financial accommodations. 
 WHEREAS, in connection with the foregoing, Borrowers have requested that Agent and
Lenders amend certain provisions of the Loan Agreement as hereafter provided, and Agent and Lenders are willing to do so on the terms and conditions hereafter set forth. 
 NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows: 

1. Definitions. All capitalized terms not otherwise defined herein shall have the meanings given to them in the Loan Agreement.

 2. Amendments to the Loan Agreement. 

 (a) Section 1.2 is amended to add the following defined terms in the proper
alphabetical order: 
 “Amendment No. 4” means that certain Amendment No. 4 to
this Agreement among Agent, Lenders, and Borrowers dated as of July 20, 2012. 
 “Applicable
Percentage” means, as of October 1, 2012, 0.250% per annum. Effective as of the first Business Day following receipt by Agent of the quarterly financial statements of Borrowers on a Consolidated Basis for the fiscal quarter
ending September 30, 2012 required under Section 9.8, and thereafter upon receipt of subsequent quarterly financial statements of Borrowers on a Consolidated Basis required under Section 9.8 for the previous fiscal quarter (each day
of such delivery, a “Applicable Percentage Adjustment Date”), the Applicable Percentage shall be adjusted, if necessary, to the applicable percent per annum set forth in the table set forth below corresponding to the Senior
Leverage Ratio for the trailing twelve month period ending on the last day of the most recently completed fiscal quarter prior to the Applicable Percentage Adjustment Date: 

 

					
	 SENIOR LEVERAGE RATIO
	  	APPLICABLE PERCENTAGE	 
	 Less than or equal to 1.5 to 1.0
	  	 	0.250	% 
	 Greater than 1.5 to 1.0
	  	 	0.375	% 

 If the Borrowers shall fail to deliver the financial statements, certificates and/or other
information required under Section 9.8 by the date required pursuant to such section, each Applicable Percentage shall be conclusively presumed to equal the highest Applicable Percentage specified in the table set forth above until the date of
delivery of such financial statements, certificates and/or other information, at which time the rate will be adjusted based upon the Senior Leverage Ratio reflected in such statements. 

If, as a result of any restatement of, or other adjustment to, the financial statements of Borrowers on a Consolidated
Basis or for any other reason, the Agent determines that (a) the Senior Leverage Ratio as previously calculated as of any applicable date was inaccurate, and (b) a proper calculation of the Senior Leverage Ratio would have resulted in a
different Applicable Percentage used in calculating the amount of a Facility Fee, then (i) if the proper calculation of the Senior Leverage Ratio would have resulted in a higher Applicable Percentage for purposes of calculating the amount of a
Facility Fee, the Borrowers shall automatically and retroactively be obligated to pay to the Agent, promptly upon demand by the Agent, an amount equal to the excess of the amount of the Facility Fee that should have been paid over the amount of the
Facility Fee 

  
 2 

 
actually paid; and (ii) if the proper calculation of the Senior Leverage Ratio would have resulted in a lower Applicable Percentage for purposes of calculating the amount of a Facility Fee,
Lenders shall repay any excess Facility Fee to the Borrowers; provided, that, if as a result of any restatement or other event a proper calculation of the Applicable Percentage would have resulted in a higher Facility Fee for one or more fiscal
quarters and a lower Facility Fee for one or more fiscal quarters (due to the shifting of income or expenses from one period to another period or any similar reason), then the amount payable by the Borrowers pursuant to clause (i) above shall
be based upon the excess, if any, of the amount of the Facility Fees that should have been paid for all applicable periods over the amounts of the Facility Fees actually paid for such periods, and the amount payable by the Lenders pursuant to clause
(ii) above shall be based upon the excess, if any, of the Facility Fees actually paid for all applicable periods over the amounts of the Facility Fees that should have been paid for such periods. 

“Facility Fees” means the fees described in Section 3.3(b). 

“Indebtedness for Borrowed Money” means, in relation to any Person at any particular time, all
Indebtedness: (a) in respect of any money borrowed, including letters of credit and acceptance facilities; (b) under or in respect of any contingent obligation (whether direct or indirect) of any money borrowed; (c) evidenced by any
loan or credit agreement, promissory note, debenture, bond, guaranty or other similar written obligation to pay money; (d) any Capital Lease Obligation; and (e) for the deferred and unpaid purchase price of any property or business or any
services (other than trade accounts payable incurred in the ordinary course of business and constituting current liabilities not more than 60 days in arrears measured from the date of billing), all as determined in accordance with GAAP. 

“Senior Debt” shall mean, as of any date of determination, all Indebtedness for Borrowed Money of
Borrowers on a Consolidated Basis, except any Indebtedness of Borrowers subordinated to the Obligations on terms and conditions satisfactory to Agent and the Required Lenders. 

“Senior Leverage Ratio” shall mean the ratio, as of the last day of a fiscal quarter, resulting
from dividing: (a) the Senior Debt as of such date by (b) EBITDA for the period equal to the four consecutive fiscal quarters then ending. 
 (b) The definition of “Applicable Margin” in Section 1.2 of the Loan Agreement is amended in its entirety to read as follows: 

“Applicable Margin” for Revolving Advances shall mean, as of June 1, 2012, the applicable
percentage specified below: 

  
 3 

					
	 APPLICABLE MARGIN FOR
   DOMESTIC RATE LOANS
	  	APPLICABLE MARGIN FOR
EURODOLLAR RATE LOANS	 
	 0.25%
	  	 	1.75	% 

 Thereafter, effective as of the first Business Day following receipt by Agent of the
quarterly financial statements of Borrowers on a Consolidated Basis for the fiscal quarter ending September 30, 2012 required under Section 9.8, and thereafter upon receipt of subsequent quarterly financial statements of Borrowers on a
Consolidated Basis required under Section 9.8 for the previous fiscal quarter (each day of such delivery, an “Adjustment Date”), the Applicable Margin for each type of Advance shall be adjusted, if necessary, to the
applicable percent per annum set forth in the table set forth below corresponding to the Senior Leverage Ratio for the trailing twelve month period ending on the last day of the most recently completed fiscal quarter prior to the applicable
Adjustment Date: 
  

									
	 SENIOR LEVERAGE RATIO
	  	APPLICABLE
MARGINS FOR
DOMESTIC
RATE LOANS	 	 	APPLICABLE
MARGINS FOR
EURODOLLAR
RATE LOANS	 
	 Less than or equal to 1.5 to 1.0
	  	 	0.25	% 	 	 	1.75	% 
	 Greater than 1.5 to 1.0
	  	 	0.50	% 	 	 	2.00	% 

 If the Borrowers shall fail to deliver the financial statements, certificates and/or other
information required under Sections 9.7 or 9.8 by the date required pursuant to such section, the Applicable Margin shall be conclusively presumed to equal the highest Applicable Margin specified in the table set forth above until the date of
delivery of such financial statements, certificates and/or other information, at which time the rate will be adjusted based upon the Senior Leverage Ratio reflected in such statements. 

If, as a result of any restatement of, or other adjustment to, the financial statements of Borrowers on a Consolidated Basis or for any
other reason, the Agent determines that (a) the Senior Leverage Ratio as previously calculated as of any applicable date was inaccurate, and (b) a proper calculation of the Senior Leverage Ratio would have resulted in different pricing for
any period, then (i) if the proper calculation of the Senior Leverage Ratio would have resulted in higher pricing for such period, the Borrowers shall automatically and retroactively be obligated to pay to the Agent, promptly upon demand by the
Agent, an amount equal to the excess of the amount of interest that should have been paid during such period over the amount of the interest actually paid for such period; and 

  
 4 

 
(ii) if the proper calculation of the Senior Leverage Ratio would have resulted in lower pricing for such period, Lenders shall repay any excess interest to the Borrowers; provided, that, if as a
result of any restatement or other event a proper calculation of the Applicable Margin would have resulted in higher interest for one or more fiscal quarters and lower interest for one or more fiscal quarters (due to the shifting of income or
expenses from one period to another period or any similar reason), then the amount payable by the Borrowers pursuant to clause (i) above shall be based upon the excess, if any, of the amount of interest that should have been paid for all
applicable periods over the amounts of interest actually paid for such periods, and the amount payable by the Lenders pursuant to clause (ii) above shall be based upon the excess, if any, of the interest actually paid for all applicable periods
over the amounts of interest that should have been paid for such periods. 
 (c) The definition of “Compliance
Certificate” in Section 1.2 of the Loan Agreement is amended in its entirety to read as follows: 
 “Compliance Certificate” shall mean a compliance certificate to be signed by the Chief Executive Officer, President, Chief Financial Officer, Director-Treasury &
Forecasting, or Corporate Controller of Borrowing Agent, which shall state that, based on an examination sufficient to permit such officer to make an informed statement, no Default or Event of Default exists, or if such is not the case, specifying
such Default or Event of Default, its nature, when it occurred, whether it is continuing and the steps being taken by Borrowers with respect to such default and, such certificate shall have appended thereto calculations which set forth
Borrowers’ compliance with the requirements or restrictions imposed by Sections 6.5, 7.4, 7.5, 7.6, 7.7, 7.8, 7.10 and 7.11. When delivered with the reports required under Sections 9.7 and 9.8, the Compliance Certificate shall include or have
appended thereto calculations of the Senior Leverage Ratio for the four fiscal quarter period ending on the last day of the most recent fiscal quarter included in such report. 

(d) The definition of “Early Termination Date” is deleted. 

(e) Section 3.3(b) is hereby amended to in its entirety read as follows: 

(b) Facility Fee. If, during any calendar quarter during the Term, the average daily unpaid balance of the
Revolving Advances and undrawn amount of any outstanding Letters of Credit for each day of such calendar quarter does not equal the Maximum Revolving Advance Amount, then Borrowers shall pay to Agent for the ratable benefit of Lenders a fee at a
rate equal to the Applicable Percentage on the amount by which the Maximum Revolving Advance Amount exceeds such average daily unpaid balance. This fee is payable to Agent in arrears on 

  
 5 

 
the first day of each calendar quarter with respect to the previous calendar quarter and on the last day of the Term. For purposes of calculating this fee, the Applicable Percentage is the
Applicable Percentage in effect on the day the fee is payable to Agent. 
 With respect to the calendar quarter
ending June 30, 2012 only, the fee shall be calculated as follows: (a) (i) 1.00% per annum multiplied by (ii) the amount by which the Maximum Revolving Advance Amount exceeds the average daily unpaid balance for the period
from April 1, 2012 to May 31, 2012, plus (b) (i) 0.25% per annum multiplied by (ii) the amount by which the Maximum Revolving Advance Amount exceeds the average daily unpaid balance for the period from June 1, 2012
to June 30, 2012. 
 (f) Section 7.6 of the Loan Agreement is amended to read as follows: 

7.6 Capital Expenditures. Contract for, purchase or make any expenditure or commitments for Capital Expenditures in
any fiscal year in an aggregate amount for all Borrowers in excess of $5,000,000. 
 (g) Section 9.2 of the
Loan Agreement is amended to read as follows: 
  

	 	9.2.	 Schedules. Deliver, or cause Borrowing Agent to deliver, to Agent on or before the fifteenth (15th) day of each month, a Borrowing Base
Certificate in form and substance satisfactory to Agent (which shall be calculated as of the last day of the prior month and which shall not be binding upon Agent or restrictive of Agent’s rights under this Agreement); provided that if no
Revolving Advances are outstanding then Borrowing Base Certificates must be provided to Agent within 15 days after the end of each of Borrowers’ fiscal quarters (which shall be calculated as of the last day of the prior quarter and which shall
not be binding upon Agent or restrictive of Agent’s rights under this Agreement); provided further that if Borrowers request an Advance when Borrowers are only obligated to provide quarterly Borrowing Base Certificates, Borrowers must submit
with that Advance request a Borrowing Base Certificate completed as of the most recent month-end. Each Borrower shall deliver, or cause Borrowing Agent to deliver, to Agent with each Borrowing Base Certificate (a) accounts receivable agings
inclusive of reconciliations to the general ledger, (b) accounts payable schedules inclusive of reconciliations to the general ledger, and (c) Inventory reports, in each case calculated as of the calculation date of the applicable

Agent may require: (i) confirmatory assignment schedules, (ii) copies of Customer’s invoices, (iii) evidence of shipment or delivery, and (iv) such further schedules,
documents and/or information regarding the Collateral as Agent may require including trial balances and test verifications. Agent shall have the right to confirm and verify all Receivables by any manner and through any medium it considers advisable
and do whatever it may deem reasonably necessary to protect its interests hereunder. The items to be provided under this Section are to be in form satisfactory to Agent and executed by each Borrower and delivered to Agent from time to time solely
for Agent’s convenience in maintaining records of the Collateral, and any Borrower’s failure to deliver any of such items to Agent shall not affect, terminate, modify or otherwise limit Agent’s Lien with respect to the Collateral.

creditors’ rights generally, and as limited by laws relating to the availability of specific performance, injunctive relief, or other equitable remedies. The Company is in compliance with all material terms of the Material Contracts, and there
has not occurred any breach, violation or default or any event that, with the lapse of time, the giving of notice or the election of any Person, or any combination thereof, would constitute a breach, violation or

default by the Company under any such Material Contract or, to the knowledge of the Company, by any other Person to any such contract except where such breach, violation or default would not have
a Material Adverse Effect. To the knowledge of the Company, it has not been notified that any party to any Material Contract intends to cancel, terminate, not renew or exercise an option under any Material Contract, whether in connection with the

 (p) No Integrated Offering. Neither the
Company, nor any of its affiliates, or any Person acting on its behalf, has, directly or indirectly, made any offers or sales of any security or solicited any offers to buy any security, under circumstances that would require registration of any of
the Shares under the Securities Act or cause this offering of the Shares to be integrated with prior offerings by the Company for purposes of the Securities Act. None of the Company, its affiliates, or any Person acting on its behalf, will take any
action or steps referred to in the preceding sentence that would require registration of the offer, issuance or sale of any of the Shares under the Securities Act or cause the offering of the Shares to be integrated with other offerings. 

(q) No Directed Selling Efforts. None of the Company, its affiliates nor any person acting on its or their behalf (other than the
Placement Agent in connection with this Agreement) has engaged or will engage in any directed selling efforts (as that term is defined in Regulation S) with respect to the Shares and each of the Company, its affiliates and any person acting on its

(t) Application of Takeover Protections; Rights Agreement. The Company and its Board of Directors have taken all necessary action,
if any, in order to render inapplicable any control share acquisition, business combination, poison pill (including any distribution under a rights agreement) or other similar anti-takeover provision under its certificate of incorporation or the
laws of the jurisdiction of its formation or otherwise which is or could become applicable to any Purchaser as a result of the transactions contemplated by this Agreement or any Transaction Document, including, without limitation, the Company’s
issuance of the Shares and any Purchaser’s ownership of the Shares. The Company has not adopted a stockholder rights plan or similar arrangement relating to accumulations of beneficial ownership of any of its common stock or a change of control

to believe that it has received or will receive, any notice of proceedings relating to the revocation or modification of, or non-compliance with, any such certificate, authorization or permit which, singly or in the aggregate, if the subject of an
unfavorable decision, ruling or finding, could result in a Material Adverse Effect.

Company.

against the Company by reason of the activities presently conducted or proposed to be conducted by the Company, nor, to the Company’s knowledge, is there any basis therefor. 

(x) Insurance. The Company is insured by institutions believed to be recognized, financially sound and reputable, with policies in
such amounts and with such deductibles and covering such risks as are generally deemed adequate and customary for its business including, but not limited to, policies covering real and personal property owned or leased by the Company against theft,
damage, destruction and acts of vandalism. The Company 

  
 - 11 -

 
has no reason to believe that it will not be able: (i) to renew its existing insurance coverage as and when such policies expire; or (ii) to obtain comparable coverage from similar
institutions as may be necessary or appropriate to conduct its business as now conducted and at a cost that would not result in a Material Adverse Effect. The Company has not been denied any insurance coverage which it has sought or for which it has
applied. 
 (y) Foreign Corrupt Practices Act. Neither the Company nor its subsidiary nor, to the knowledge of the
Company, any director, officer, agent, employee, affiliate or other person acting on behalf of the Company or its subsidiary is aware of or has taken any action, directly or indirectly, that has resulted or would result in a violation of the Foreign
Corrupt Practices Act of 1977, as amended, and the rules and regulations thereunder (the “FCPA”), including, without limitation, making use of the mails or any means or instrumentality of interstate commerce corruptly in
furtherance of an offer, payment, promise to pay or authorization of the payment of any money, or other property, gift, promise to give, or authorization of the giving of anything of value to any “foreign official” (as such term is defined

conducted their respective businesses in compliance with the FCPA and have instituted and maintain policies and procedures designed to ensure, and which are reasonably expected to continue to ensure, continued compliance therewith. 

(z) Disclosure Controls and Procedures; Deficiencies in or Changes to Internal Control Over Financial Reporting. The Company has
established and maintains disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)), which: (i) are designed to ensure that material information relating to the Company is made known to the Company’s
principal executive officer and its principal financial officer by others within those entities, particularly during the periods in which the periodic reports required under the Exchange Act are being prepared; (ii) have been evaluated for
effectiveness as of a date within 90 days prior to the date that the Company filed its most recent annual or quarterly report with the Commission; and (iii) are effective in all material respects to perform the functions for which they were

with its employees are good. No executive officer of the Company has notified the Company that such officer intends to leave the Company or otherwise terminate such officer’s employment with the Company. To the Company’s knowledge, no
executive officer of the Company is in violation of any material term of any employment contract, confidentiality, disclosure or proprietary information agreement, non-competition agreement, or any other contract or agreement or any restrictive
covenant, with any Person other than the Company, and the continued employment of each such executive officer does not subject the Company to any liability with respect to any of the foregoing matters. 

(bb) Title to Properties. The Company has good and marketable title to all of the real and personal property and other assets
reflected as owned in the financial statements referred to in Subsection h above, in each case free and clear of any security interests, mortgages, pledges, liens, charges, encumbrances, adverse claims and other defects, except Permitted
Liens and such as do not materially and adversely affect the value of such property and do not materially interfere with the use made or proposed to be made of such property by the Company. The real property, improvements, equipment and personal

equipment; or (b) existing on such equipment at the time of its acquisition, provided that the Lien is confined solely to the property so acquired and improvements thereon, and the proceeds of such equipment; (5) Liens incurred in
connection with the extension, renewal or refinancing of the indebtedness secured by Liens of the type described in clauses (1) through (4) above, provided that any extension, renewal or replacement Lien shall be limited to the property
encumbered by the existing Lien and the principal amount of the Indebtedness being extended, renewed or refinanced does not increase; (6) leases, subleases, licenses and sublicenses granted to others in the ordinary course of the Company’s
business, not interfering in any material respect with the business of the Company and its Subsidiaries taken as a whole; and (7) Liens in favor of customs and revenue authorities arising as a matter of law to secure payments of custom duties

default thereunder, and to the knowledge of the Company no event has occurred which, with notice or lapse of time, would constitute such a breach or default or permit termination, modification or acceleration thereunder; and 

(vii) each option, license, sublicense or agreement of any kind covering the item is legal, valid, binding, enforceable and in full
force and effect. 
 (c) All registered patents, copyrights, trademarks and service marks included in the Company Intellectual

the conduct of the Company’s businesses as presently conducted, will violate or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant, or instrument under which any such Key Employee

data use that are commercially reasonable and, in any event, comply with the Company’s obligations to its customers and applicable laws, rules and regulations. To the knowledge of the Company, there have not been, and the transaction
contemplated under this Agreement will not result in, any security breaches of any security policy, data use restriction or privacy breach under any such policies or any applicable laws, rules or regulations. 

(dd) Compliance With Environmental Laws. Except as would not, singly or in the aggregate, result in a Material Adverse Effect:
(i) the Company is not in violation of any federal, state or local statute, law, rule, regulation, ordinance, code, policy or rule of common law or any judicial or administrative interpretation thereof, including any judicial or administrative
order, consent, decree or judgment, relating to pollution or protection of human health, the environment (including, without limitation, ambient air, surface water, groundwater, land surface or subsurface strata) or wildlife, including, without
limitation, laws and regulations relating to the release or threatened release of chemicals, pollutants, contaminants, wastes, toxic substances, hazardous substances, petroleum or petroleum products (collectively, “Hazardous
Materials”) or to the manufacture, processing, distribution, use, treatment, storage, disposal, transport or handling of Hazardous Materials (collectively, “Environmental Laws”); (ii) the Company has all
permits, authorizations and approvals required under any applicable Environmental Laws and is in material compliance with their requirements; (iii) there are no pending or, to the Company’s knowledge, threatened administrative, regulatory

franchise tax returns or has properly requested extensions thereof and has paid all taxes required to be paid by it and, if due and payable, any related or similar assessment, fine or penalty levied against it. The Company has made adequate charges,

finally determined.

maintains a system of accounting controls sufficient to provide reasonable assurances that: (i) transactions are executed in accordance with management’s general or specific authorization; (ii) transactions are recorded as necessary
to permit preparation of financial statements in conformity with GAAP and to maintain accountability for assets; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the

 - 16 -

 (gg) Compliance With ERISA. The Company and any “employee benefit
plan” (as defined under the Employee Retirement Income Security Act of 1974, as amended, and the regulations and published interpretations thereunder (collectively, “ERISA”)) established or maintained by the
Company, or its ERISA Affiliates (as defined below) are in compliance in all material respects with ERISA. “ERISA Affiliate” means, with respect to the Company, any member of any group of organizations described in Sections
414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended, and the regulations and published interpretations thereunder (the “Code”) of which the Company is a member. No “reportable
event” (as defined under ERISA) has occurred or is reasonably expected to occur with respect to any “employee benefit plan” established or maintained by the Company, or any of its ERISA Affiliates. No
“employee benefit plan” established or maintained by the Company, or any of its ERISA Affiliates, if such “employee benefit plan” were terminated, would have any “amount of unfunded benefit
liabilities” (as defined under ERISA). Neither the Company, nor any of its ERISA Affiliates has incurred or reasonably expects to incur any liability under (i) Title IV of ERISA with respect to termination of, or withdrawal from,
any “employee benefit plan” or (ii) Sections 412, 4971, 4975 or 4980B of the Code. Each “employee benefit plan” established or maintained by the Company, or any of its ERISA Affiliates that is
intended to be qualified under Section 401(a) of the Code is so qualified and nothing has occurred, whether by action or failure to act, which would cause the loss of such qualification. 

(hh) No Outstanding Loans or Other Extensions of Credit. The Company has not extended or maintained credit, arranged for the
extension of credit, or renewed any extension of credit, in the form of a personal loan, to or for any director or executive officer (or equivalent thereof) of the Company except for such extensions of credit as are: (i) expressly permitted by
Section 13(k) of the Exchange Act; or (ii) fully repaid, discharged, forgiven or otherwise no longer outstanding or owing in any way on the date of this Agreement. 
 (ii) Compliance with Laws. The Company has not been advised, and has no reason to believe, that it is not conducting business in compliance with all applicable laws, rules and regulations of the
jurisdictions in which it is conducting business, except where failure to be so in compliance would not result in a Material Adverse Effect. The Company: 
 (i) has not, since January 1, 2011, received any FDA Form 483, notice of adverse finding, warning letter, untitled letter or other correspondence or notice from the U.S. Food and Drug Administration
(the “FDA”) or any other federal, state, local or foreign governmental or regulatory authority alleging or asserting material noncompliance with any Applicable Laws or any licenses, certificates, approvals, clearances,
authorizations, permits and supplements or amendments thereto required by any such Applicable Laws (“Authorizations”); 
 (ii) possesses all material Authorizations and such Authorizations are valid and in full force and effect and the Company is not in material violation of any term of any such Authorizations; 

(iii) has not received notice of any claim, action, suit, proceeding, hearing, enforcement, investigation, arbitration or other action
from the FDA or any other federal, state, local or foreign governmental or regulatory authority or third party alleging that 

  
 - 17 -

 
any product operation or activity is in material violation of any Applicable Laws or Authorizations and has no knowledge that the FDA or any other federal, state, local or foreign governmental or
regulatory authority or third party is considering any such claim, litigation, arbitration, action, suit, investigation or proceeding; 
 (iv) has not received notice that the FDA or any other federal, state, local or foreign governmental or regulatory authority has taken, is taking or intends to take action to limit, suspend, modify or
revoke any material Authorizations and has no knowledge that the FDA or any other federal, state, local or foreign governmental or regulatory authority is considering such action; 

(v) has filed, obtained, maintained or submitted all material reports, documents, forms, notices, applications, records, claims,
submissions and supplements or amendments as required by any Applicable Laws or Authorizations and that all such reports, documents, forms, notices, applications, records, claims, submissions and supplements or amendments were materially complete
and correct on the date filed (or were corrected or supplemented by a subsequent submission); and 
 (vi) has not, either
voluntarily or involuntarily, initiated, conducted, or issued or caused to be initiated, conducted or issued, any recall, market withdrawal or replacement, safety alert, “dear doctor” letter, or other notice or action
relating to the alleged lack of safety or efficacy of any product or any alleged product defect or violation and, to the Company’s knowledge, no third party has initiated, conducted or intends to initiate any such notice or action. 

The studies, tests and preclinical and clinical trials conducted by or on behalf of the Company were and, if still pending, are being
conducted in accordance with experimental protocols, procedures and controls pursuant to accepted professional scientific standards and all Applicable Laws and Authorizations, including, without limitation, the Federal Food, Drug and Cosmetic Act
and the rules and regulations promulgated thereunder (collectively, “FFDCA”); the descriptions of the results of such studies, tests and trials contained in the SEC Reports are accurate and fairly present the data derived
from such studies, tests and trials; the Company is not aware of any studies, tests or trials, the results of which the Company believes reasonably call into question the study, test, or trial results described or referred to in the SEC Reports when
viewed in the context in which such results are described and the clinical state of development; and, since January 1, 2009, the Company has not received any notices or correspondence from the FDA or any other federal, state, local or foreign
governmental or regulatory authority requiring the termination, suspension or material modification of any studies, tests or preclinical or clinical trials conducted by or on behalf of the Company. 

(jj) No Price Stabilization or Manipulation; Compliance with Regulation M, etc. The Company has not taken, directly or indirectly,
any action designed to or that might be reasonably expected to cause or result in stabilization or manipulation of the price of the Shares or any other “reference security” (as defined in Rule 100 of Regulation M under the
1934 Act (“Regulation M”)), whether to facilitate the sale or resale of the Shares or otherwise, and has taken no action which would directly or indirectly violate Regulation M or facilitate any short-selling of the Shares
offered or the underlying Shares by Purchasers. 

  
 - 18 -

 (kk) Company Not an “Investment Company.” The Company has been advised of
the rules and requirements under the Investment Company Act of 1940, as amended, and the rules and regulations of the Commission thereunder (collectively, the “Investment Company Act”). The Company is not, and after receipt
of payment for the Shares will not be, an “investment company” within the meaning of the Investment Company Act. 
 (ll) Brokers. Except for Jefferies & Company, Inc., there is no broker, finder or other party that is entitled to receive from the Company any brokerage or finder’s fee or other fee
or commission as a result of the Placement or the transactions contemplated thereby. 
 Section 4. Covenants.

 (b) Form D and Blue Sky. The Company
agrees to file a Form D with respect to the Shares as required under Regulation D and to comply with any applicable state securities and “Blue Sky” laws in connection with the sale of the Shares. The Company shall, on or
before the Closing Date, take such action as the Company shall reasonably determine is necessary in order to obtain an exemption for or to qualify the Shares for sale to the Purchasers at the Closing pursuant to this Agreement under applicable
securities or “Blue Sky” laws of the states of the United States (or to obtain an exemption from such qualification), and shall provide evidence of any such action so taken to the Placement Agent on or prior to the Closing
Date. The Company shall make all filings and reports relating to the offer and sale of the Shares required under applicable securities or “Blue Sky” laws of the states of the United States following the Closing Date.

 (c) Financial Information. From the Closing Date until the first anniversary of the Closing, the Company will make

(i) within one Business Day after the filing thereof with the Commission, a copy of its Annual Reports and Quarterly Reports on Form 10-K or 10-Q, any interim reports or any consolidated balance sheets, income statements, stockholders’
equity statements and/or cash flow statements for any period other than annual, any Current Reports on Form 8-K and any registration statements (other than on Form S-8) or amendments filed pursuant to the Securities Act; and (ii) copies of any
notices and other information made available or given to the stockholders of the Company generally, contemporaneously with the making available or giving thereof to the stockholders. 

(d) Fees and Expenses. Except as otherwise set forth in the Transaction Documents, each party to this Agreement shall bear its own
expenses in connection with the sale of the Shares to the Purchasers. 

  
 - 19 -

 (e) General Solicitation. Neither the Company nor any of its Affiliates have
engaged, and will engage, directly or indirectly in any form of “general solicitation” or “general advertising” in connection with the offering of the Shares (as those terms are used in Regulation D)
under the Securities Act or in any manner involving a public offering within the meaning of Section 4(2); and the Company has not entered, and will not enter, into any arrangement or agreement with respect to the distribution of the Shares,
except for this Agreement and the Resale Registration Rights Agreement, and the Company agrees not to enter into any such arrangement or agreement. “Affiliate” shall have the meaning ascribed to such term in Rule 12b-2 of the
General Rules and Regulations under the Exchange Act. 
 (f) Integration. Neither the Company nor any of its Affiliates
has directly or indirectly sold, offered for sale, solicited offers to buy or otherwise negotiated in respect of any “security” (as defined in the Securities Act) that is, or would be, integrated with the sale of any of the
Shares in a manner that would require the registration under the Securities Act of any of the Shares. 
 (g) Publicity.
The Company agrees that it will not, and shall cause each of its Subsidiaries to not, without the prior written consent of a Purchaser, use in advertising, publicity, or otherwise the name of such Purchaser, or any partner or employee of such
Purchaser, nor any trade name, trademark, trade device, service mark, symbol or any abbreviation, contraction or simulation thereof owned by such Purchaser or any of their respective affiliates, except: (a) in any registration statement in
which such Purchaser is identified as a selling security holder, or (b) to the extent required by law or legal process, in which case the Company shall provide such Purchaser with prior notice of such disclosure. The Company further agrees
that it shall obtain the written consent of such Purchaser prior to the Company’s or any of its Subsidiaries’ issuance of any public statement detailing the purchase of Shares by Purchasers pursuant to this Agreement other than to the
extent required by law or legal process, in which case the Company shall only be required to provide such Purchaser with prior notice of such disclosure. 
 (h) Confidentiality After The Date Hereof. Each Purchaser, severally and not jointly with the other Purchasers, covenants that until such time as the transactions contemplated by this Agreement and
such other material non-public information related to the Company in possession of the Purchaser are publicly disclosed by the Company as described in Subsection (i), such Purchaser will maintain the confidentiality of all disclosures made to
it in connection with this transaction (including the existence and terms of this transaction). 
 (i) Securities Laws

contemplated hereby, and filing the Transaction Documents as exhibits thereto. From and after the issuance of the Press Release, no Purchaser shall be in possession of any material, non-public information received from the Company or any of its
officers, directors, employees or agents, that is not disclosed in the Press Release. Notwithstanding the foregoing, the Company shall not publicly disclose the name of any Purchaser, or include the name of any Purchaser in any filing with the

Company shall timely file all reports required to be filed with the Commission pursuant to the Exchange Act, and the Company shall not terminate its status as an issuer required to file reports under the Exchange Act even if the Exchange Act or the

(b) Independent Nature of Purchaser’s Obligations and Rights. The obligations of each Purchaser under this Agreement are
several and not joint with the obligations of each other Purchaser, and no Purchaser shall be responsible in any way for the performance of the obligations of any other Purchaser under this Agreement. Nothing contained herein or in any Transaction
Document, and no action taken by any Purchaser pursuant thereto, shall be deemed to constitute the Purchaser as a partnership, an association, a joint venture or any other kind of entity, or create a presumption that the Purchasers are in any way
acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any other Transaction Document. Each Purchaser acknowledges that no other Purchaser will be acting as agent of such Purchaser in
enforcing its rights under this Agreement. Each Purchaser shall be entitled to independently protect and enforce its rights, including without limitation the rights 

  
 - 23 -

 
arising out of this Agreement, and it shall not be necessary for any other Purchaser to be joined as an additional party in any Proceeding for such purpose. The Company acknowledges that each of
the Purchasers has been provided with the same Resale Registration Rights Agreement for the purpose of closing a transaction with multiple Purchasers and not because it was required or requested to do so by any Purchaser.

of the State of California. Each party hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in The City of San Francisco for the adjudication of any dispute hereunder or in connection herewith or with any
transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action
or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each party hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address for such notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and notice thereof. Nothing contained herein shall be
deemed to limit in any way any right to serve process in any manner permitted by law. Each party hereby irrevocably waives any right it may have, and agrees not to request, a jury trial for the adjudication of any dispute hereunder or in connection
with or arising out of this Agreement or any transaction contemplated hereby. If either party shall commence a proceeding to enforce any provisions of this Agreement, then the prevailing party in such proceeding shall be reimbursed by the other
party for its attorney’s fees and other costs and expenses incurred with the investigation, preparation and prosecution of such proceeding. 
 (d) Amendments and Waivers. No provision of this Agreement may be amended or waived other than by an instrument in writing signed by the Company and each Purchaser, and any amendment to or waiver
of this Agreement made in conformity with the provisions of this Section 8(d) shall be binding on all Purchasers. 

(e) Further Assurances. Each party shall do and perform, or cause to be done and performed, all such further acts and things, and
shall execute and deliver all such other agreements, certificates, instruments and documents, as any other party may reasonably request in order to carry out the intent and accomplish the purposes of this Agreement and the consummation of the
transactions contemplated hereby.

agreements (except any confidentiality or nondisclosure agreements entered into among the parties (the “Prior Confidentiality Agreements”) and those certain side letters entered into between the Company and certain Purchasers
dated as of July 25, 2012 (the “Side Letters”)), among the parties hereto and persons acting on their behalf with respect to the matters discussed herein, and the Transaction Documents, the Prior Confidentiality Agreements
and the Side Letters contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, none of the parties hereto makes any representation, warranty,
covenant or undertaking with respect to such matters. 

  
 - 24 -

 (g) Successors and Assigns. This Agreement shall be binding upon and inure to the
benefit of the parties hereto and their respective successors and assigns; provided that no party shall assign any of its rights or obligations hereunder without the prior written consent of the other party. 

(h) Massachusetts Business Trust. A copy of the Agreement and Declaration of Trust of each Purchaser or any affiliate thereof is
on file with the Secretary of State of the Commonwealth of Massachusetts and notice is hereby given that this Agreement is executed on behalf of the trustees of such Purchaser or any affiliate thereof as trustees and not individually and that the
obligations of this Agreement are not binding on any of the trustees, officers or stockholders of such Purchaser or any affiliate thereof individually but are binding only upon such Purchaser or any affiliate thereof and its assets and property.

 (i) Counterparts; Facsimile Copies. This Agreement may be executed in any number of counterparts, each of which when
so executed shall be deemed to be an original and, all of which taken together shall constitute one and the same Agreement. In the event that any signature is delivered by facsimile transmission, such signature shall create a valid binding
obligation of the party executing (or on whose behalf such signature is executed) the same with the same force and effect as if such facsimile signature were the original thereof. 

(j) Severability. If any provision of this Agreement shall be invalid, unenforceable, illegal or void in any jurisdiction, such
invalidity, unenforceability, illegality or voidness shall not affect the validly or enforceability of the remainder of this Agreement in that jurisdiction or the validity or enforceability of any provision of this Agreement in any other
jurisdiction. In that case, the parties hereto shall use their reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision. It is hereby stipulated and
declared to be the intention of the parties that they would have executed the remaining provisions without including any of such that may be hereafter declared invalid, illegal, void or unenforceable. 

(k) Headings. The headings of this Agreement are for convenience of reference and shall not form part of, or affect the
interpretation of, this Agreement. 
 (l) No Third Party Beneficiaries. This Agreement is intended for the benefit of the
parties hereto and their respective permitted successors and assigns, and is not for the benefit of, nor may any provision hereof be enforced by, any other Person except as provided in the next paragraph.
