such Person, (ii) of any Subsidiary of such Person or (iii) of any Person described in clause (a) above. For the purposes of this definition, control of a Person shall mean the power (direct or indirect) to direct or cause the

Obligations (as defined in each Security Document). 
 (II) The Company, without the prior written consent of the Purchaser, shall not, and
shall not permit any of its Subsidiaries to, create or acquire any Subsidiary after the date hereof unless (i) such Subsidiary is a wholly-owned Subsidiary of the Company or an international Subsidiary (which may have shareholders) and

Subsidiary were a Subsidiary 

  

 21 

 
on the Closing Date. It is agreed and understood that to the extent that any international Subsidiary that is created or acquired after the date hereof is a
non-Credit Party (each, a “New Non-Credit Party Subsidiary”), the capitalization of such New Non-Credit Party Subsidiary shall come from sources other than the Company or any of its other Subsidiaries. Furthermore, the Company and
its Subsidiaries (other than the New Non-Credit Party Subsidiaries) shall otherwise be prohibited from investing in, lending to, contributing and/or transferring any assets to and/or providing any form of financial assistance to, whether directly or
indirectly, such New Non-Credit Party Subsidiary; provided that this prohibition does not limit the Company or a New Non-Credit Party Subsidiary from entering into a license agreement (to be negotiated on an arm’s length basis) to sell its
instrumentation internationally on a cost plus basis. 
 6.12 Opinion. On the Closing Date, the Company will deliver to the Purchaser
an opinion acceptable to the Purchaser from the Company’s in-house legal counsel. 
 6.13 Margin Stock. The Company will not
permit any of the proceeds of the Note to be used directly or indirectly to “purchase” or “carry” “margin stock” or to repay indebtedness incurred to “purchase” or “carry” “margin stock”
within the respective meanings of each of the quoted terms under Regulation U of the Board of Governors of the Federal Reserve System as now and from time to time hereafter in effect. 
 7. Covenants of the Purchaser. The Purchaser covenants and agrees with the Company as follows: 
 7.1 Confidentiality. The Purchaser will not disclose, and will not include in any public announcement, the name of the Company, unless expressly
agreed to by the Company or unless and until such disclosure is required by law or applicable regulation, and then only to the extent of such requirement. 
 7.2 Non-Public Information. The Purchaser will not effect any sales in the shares of the Company’s Common Stock while in possession of material, non-public information regarding the Company if such sales
would violate applicable securities law. 
 7.3 Limitation on Acquisition of Common Stock of the Company. Notwithstanding anything to
the contrary contained in this Agreement, any Related Agreement or any document, instrument or agreement entered into in connection with any other transactions between the Purchaser and the Company, the Purchaser may not acquire stock in the Company
(including, without limitation, pursuant to a contract to purchase, by exercising an option or warrant, by converting any other security or instrument, by acquiring or exercising any other right to acquire, shares of stock or other security
convertible into shares of stock in the Company, or otherwise, and such contracts, options, warrants, conversion or other rights shall not be enforceable or exercisable) to the extent such stock acquisition would cause any interest payable by the
Company to the Purchaser not to qualify as “portfolio interest” within the meaning of Section 881(c)(2) of the Code, by reason of Section 881(c)(3) of the Code, taking into account the constructive ownership rules under
Section 871(h)(3)(C) of the Code (the “Stock Acquisition Limitation”). The Stock Acquisition Limitation shall automatically become null and void without any notice to the Company upon the earlier to occur of either (a) the
Company’s delivery to the Purchaser of a Notice of Prepayment (as defined in the Note) or (b) the existence of an 

  

 22 

 
Event of Default (as defined in the Note) at a time when the average closing price of the Company’s common stock as reported by Bloomberg, L.P. on the
Principal Market for the immediately preceding five trading days is greater than or equal to $1.65. 
 8. Covenants of the Company and the
Purchaser Regarding Indemnification. 
 8.1 Company Indemnification. The Company agrees to indemnify, hold harmless, reimburse and
defend the Purchaser, each of the Purchaser’s officers, directors, agents, affiliates, control persons, and principal shareholders, against all claims, costs, expenses, liabilities, obligations, losses or damages (including reasonable legal
fees) of any nature, incurred by or imposed upon the Purchaser which result, arise out of or are based upon: (i) any misrepresentation by the Company or any of its Subsidiaries or breach of any warranty by the Company or any of its Subsidiaries
in this Agreement, any other Related Agreement or in any exhibits or schedules attached hereto or thereto; or (ii) any breach or default in performance by Company or any of its Subsidiaries of any covenant or undertaking to be performed by
Company or any of its Subsidiaries hereunder, under any other Related Agreement or any other agreement entered into by the Company and/or any of its Subsidiaries and the Purchaser relating hereto or thereto. 
 8.2 Purchaser’s Indemnification. The Purchaser agrees to indemnify, hold harmless, reimburse and defend the Company and each of the
Company’s officers, directors, agents, affiliates, control persons and principal shareholders, at all times against any claims, costs, expenses, liabilities, obligations, losses or damages (including reasonable legal fees) of any nature,
incurred by or imposed upon the Company which result, arise out of or are based upon: (i) any misrepresentation by the Purchaser or breach of any warranty by the Purchaser in this Agreement or in any exhibits or schedules attached hereto or any
Related Agreement; or (ii) any breach or default in performance by the Purchaser of any covenant or undertaking to be performed by the Purchaser hereunder, or any other agreement entered into by the Company and the Purchaser relating hereto.

 11.2 Severability. Wherever possible each provision of this Agreement and the Related Agreements shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision of this Agreement or any Related Agreement shall be prohibited by or invalid or illegal under applicable law such provision shall be ineffective to the extent of such
prohibition or invalidity or illegality, without invalidating the remainder of such provision or the remaining provisions thereof which shall not in any way be affected or impaired thereby. 
  

 24 

 11.3 Survival. The representations, warranties, covenants and agreements made herein shall survive
any investigation made by the Purchaser and the closing of the transactions contemplated hereby to the extent provided therein. All statements as to factual matters contained in any certificate or other instrument delivered by or on behalf of the
Company pursuant hereto in connection with the transactions contemplated hereby shall be deemed to be representations and warranties by the Company hereunder solely as of the date of such certificate or instrument. All indemnities set forth herein

Section 871(h)(3)(C) of the Code (the “Stock Acquisition Limitation”). The Stock Acquisition Limitation shall automatically become null and void without any notice to the Company upon the earlier to occur of either (a) the
Company’s delivery to the Purchaser of a Notice of Prepayment (as defined in the Note) or (b) the existence of an 

  

 22

Principal Market for the immediately preceding five trading days is greater than or equal to $1.65.

manner as to be effective and valid under applicable law, but if any provision of this Agreement or any Related Agreement shall be prohibited by or invalid or illegal under applicable law such provision shall be ineffective to the extent of such
prohibition or invalidity or illegality, without invalidating the remainder of such provision or the remaining provisions thereof which shall not in any way be affected or impaired thereby. 
  

 24 

 11.3 Survival. The representations, warranties, covenants and agreements made herein shall survive
any investigation made by the Purchaser and the closing of the transactions contemplated hereby to the extent provided therein. All statements as to factual matters contained in any certificate or other instrument delivered by or on behalf of the
Company pursuant hereto in connection with the transactions contemplated hereby shall be deemed to be representations and warranties by the Company hereunder solely as of the date of such certificate or instrument. All indemnities set forth herein
and all rights to payment set forth in the Royalty Agreement shall survive the execution, delivery and termination of this Agreement and the Note and the making and repayment of the obligations arising hereunder, under the Note and under the other

 11.5 Entire Agreement;
Maximum Interest. This Agreement, the Related Agreements, the exhibits and schedules hereto and thereto and the other documents delivered pursuant hereto constitute the full and entire understanding and agreement between the parties with regard

Related Agreement or in any document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of interest or other charges in excess of the maximum rate permitted by applicable law. In the
event that the rate of interest or dividends required to be paid or other charges hereunder exceed the maximum rate permitted by such law, any payments in excess of such maximum shall be credited against amounts owed by the Company to the Purchaser
