THEREFORE, in consideration of the mutual promises and covenants set forth herein, and for other consideration, the receipt and adequacy of which is hereby acknowledged, the parties hereto hereby agree as follows: 

AGREEMENT 

Section 1. Amendment to the Note Purchase Agreement. Section 7.1(a) of the Note Purchase Agreement is hereby amended and
restated in its entirety to read as follows: 
 (a) Annual Financial Statements. As soon as practicable and in any
event no later than March 31 of the calendar year immediately following the final day of each applicable fiscal year, audited financial statements of the Company and Sponsor (it being acknowledged that such requirement may be satisfied by the
delivery of the appropriate report on Form 10-K filed with the SEC, if applicable), all prepared in accordance with GAAP consistently applied and setting forth, in each case, in comparative form the
figures for the previous fiscal year. Such financial statements shall include a statement of equity, a balance sheet as of the close of such year, an income and expense statement, reconciliation of capital accounts (where applicable), a statement of
cash flow and summary results of hedging and trading activities (in the case of the Company only), reported on without a qualification arising out of the scope of the audit, and certified by an independent certified public accountant of nationally
recognized standing selected by the Person whose financial statements are being prepared. Such certificate shall not be qualified or limited because of restricted or limited examination by such accountant. The relevant accountant for the Company
shall also certify that in making the examination necessary for reporting on the foregoing financial statements no knowledge was obtained of any Default or Event of Default, except as disclosed in such certificate. 

Section 2. No Defaults or Events of Default. Except as explicitly noted to the contrary in that certain Notice under Note
Purchase Agreement delivered by the Company to the Noteholders on February 27, 2018, no Default or Event of Default under the Note Purchase Agreement has occurred and is continuing as of the Effective Date. 

  
 1 

 Section 3. Effective Date. This Amendment has been duly executed by the Company.
This Amendment shall be effective upon the receipt by, or on behalf of, the Company of duly executed counterparts of this Amendment signed by Holders constituting the Required Holders (the “Effective Date”). 

Section 4. No Other Changes or Waivers. Except as expressly provided or contemplated by this Amendment, all of
the terms, conditions and provisions of the Note Purchase Agreement remain unaltered and in full force and effect. Except as specifically provided herein, the execution, delivery and performance of this Amendment shall not be deemed as a waiver
of any other matters or any future matters. The Note Purchase Agreement and this Amendment shall be read and construed as one instrument. 

Section 5. Headings. Article and Section headings have been inserted in this Amendment as a matter of convenience for
reference only and it is agreed that such Article and Section headings are not a part of this Amendment and shall not be used in the interpretation of any provision of this Amendment. 

Section 6. Governing Law. This Amendment shall be construed and enforced in accordance with, and the rights of the parties
shall be governed by, the law of the State of New York excluding choice-of-law principles of the law of such State that would permit the application of the laws of a
jurisdiction other than such State. 
 Section 7. Severability. Any provision of this Amendment that is invalid,
illegal, prohibited or unenforceable in any respect in any jurisdiction, shall as to such jurisdiction be ineffective to the extent of such invalidity, illegality, prohibition or unenforceability without affecting, invalidating or impairing the
validity, legality and enforceability of the remaining provisions hereof; and any such invalidity, illegality, prohibition or unenforceability in any jurisdiction shall not affect, invalidate or impair such provision in any other jurisdiction. 

Section 8. Counterparts. This Amendment and any amendments, waivers, consents or supplements hereto or in connection herewith
may be executed in any number of counterparts and by different parties hereto in separate counterparts, each of which when so executed and delivered shall be deemed an original, but all such counterparts together shall constitute one and the same
instrument. Signature pages may be detached from multiple separate counterparts and attached to a single counterpart so that all signature pages are physically attached to the same document.

 Exhibit 10.32 

ION AMERICA CORPORATION 

EMPLOYMENT, CONFIDENTIAL INFORMATION, 

INVENTION ASSIGNMENT 
 AND
ARBITRATION AGREEMENT 
 April 1, 2002 

(Effective Date) 
 As a condition
of my employment with ION AMERICA CORPORATION, its subsidiaries, affiliates, successors or assigns (together, the “Company”), and in consideration of my employment with the Company and my receipt of the compensation now and hereafter paid
to me by the Company, the sufficiency of which is hereby acknowledged, I agree to the following: 
 1. At-Will Employment. I UNDERSTAND AND ACKNOWLEDGE THAT MY EMPLOYMENT WITH THE COMPANY IS FOR AN UNSPECIFIED DURATION AND CONSTITUTES “AT-WILL”
EMPLOYMENT. I ALSO UNDERSTAND THAT ANY REPRESENTATION TO THE CONTRARY IS UNAUTHORIZED AND NOT VALID UNLESS OBTAINED IN WRITING AND SIGNED BY AN OFFICER OF THE COMPANY. I ACKNOWLEDGE THAT THIS EMPLOYMENT RELATIONSHIP MAY BE TERMINATED AT ANY TIME,
WITH OR WITHOUT GOOD CAUSE OR FOR ANY OR NO CAUSE, AT THE OPTION EITHER OF THE COMPANY OR MYSELF, WITH OR WITHOUT NOTICE. 
 2.
Confidential Information. 
 (a) Company Information. I agree at all times during the term of my
employment and thereafter to hold in strictest confidence, and not to use, except for the benefit of the Company, or to disclose to any person, firm or corporation without written authorization of the Board of Directors of the Company, any
Confidential Information of the Company. I understand that “Confidential Information” means any Company proprietary information, technical data, trade secrets or know-how, including, but not limited
to, research, product plans, products, services, customer lists and customers (including, but not limited to, customers of the Company on whom I called or with whom I became acquainted during the term of my employment), markets, software,
developments, inventions, processes, formulas, technology, designs, drawings, engineering, hardware configuration information, marketing, finances or other business information disclosed to me by the Company either directly or indirectly in writing,
orally or by drawings or observation of parts or equipment. I further understand that Confidential Information does not include any of the foregoing items if such information has become publicly known and made generally available through no wrongful
act of mine or of others who were under confidentiality obligations as to the item or items involved. 
 (b) Former Employer
Information. I agree that I will not, during my employment with the Company, improperly use or disclose any proprietary information or trade secrets of any former or concurrent employer or other person or entity and that I will not bring onto
the premises of the Company any unpublished document or proprietary information belonging to any such employer, person or entity unless consented to in writing by such employer, person or entity. 

 (c) Third Party Information. I recognize that the Company has received and in the future
will receive from third parties their confidential or proprietary information subject to a duty on the Company’s part to maintain the confidentiality of such information and to use it only for certain limited purposes. I agree to hold all such
confidential or proprietary information in the strictest confidence and not to disclose it to any person, firm or corporation or to use it except as necessary in carrying out my work for the Company consistent with the Company’s agreement with
such third parties. 
 3. Inventions. 

(a) Inventions Retained and Licensed. I have attached hereto, as Exhibit A, a list describing all inventions, original works of
authorship, developments, improvements, and trade secrets which were made by me prior to my employment with the Company (collectively referred to as “Prior Inventions”), which belong to me, which relate to the Company’s proposed
business, products or research and development, and which are not assigned to the Company hereunder; or, if no such fully completed and signed list is attached, I represent that there are no such Prior Inventions. If, in the course of my employment
with the Company, I incorporate into a Company product, process or machine a Prior Invention owned by me or in which I have an interest, the Company is hereby granted and shall have a nonexclusive, royalty-free, irrevocable, perpetual, worldwide
license to make, have made, modify, use and sell such Prior Invention as part of or in connection with such product, process or machine. 

(b) Assignment of Inventions. I agree that I will promptly make full written disclosure to the Company, will hold in trust for the sole
right and benefit of the Company, and hereby assign to the Company, or its designee, all my right, title, and interest in and to any and all inventions, original works of authorship, developments, concepts, improvements, designs, discoveries, ideas,
trademarks or trade secrets, whether or not patentable or registrable under copyright or similar laws, which I may solely or jointly conceive or develop or reduce to practice, or cause to be conceived or developed or reduced to practice, during the
period of time I am in the employ of the Company (collectively referred to as “Inventions”), except as provided in Section 3(f) below. I further acknowledge that all original works of authorship which are made by me (solely or jointly
with others) within the scope of and during the period of my employment with the Company and which are protectible by copyright are “works made for hire” as that term is defined in the United States Copyright Act. I understand and agree
that the decision whether or not to commercialize or market any invention developed by me solely or jointly with others is within the Company’s sole discretion and for the Company’s sole benefit and that no royalty will be due to me as a
result of the Company’s efforts to commercialize or market any such invention. 
 (c) Inventions Assigned to the United States. I
agree to assign to the United States government all my right, title, and interest in and to any and all Inventions whenever such full title is required to be in the United States by a contract between the Company and the United States or any of its
agencies. 

  
 -2- 

 (d) Maintenance of Records. I agree to keep and maintain adequate and current written
records of all Inventions made by me (solely or jointly with others) during the term of my employment with the Company. The records will be in the form of notes, sketches, drawings, and any other format that may be specified by the Company. The
records will be available to and remain the sole property of the Company at all times. 
 (e) Patent and Copyright Registrations. I
agree to assist the Company, or its designee, at the Company’s expense, in every proper way to secure the Company’s rights in the Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating
thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments which the Company
shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any
copyrights, patents, mask work rights or other intellectual property rights relating thereto. I further agree that my obligation to execute or cause to be executed, when it is in my power to do so, any such instrument or papers shall continue after
the termination of this Agreement. If the Company is unable because of my mental or physical incapacity or for any other reason to secure my signature to apply for or to pursue any application for any United States or foreign patents or copyright
registrations covering Inventions or original works of authorship assigned to the Company as above, then I hereby irrevocably designate and appoint the Company and its duly authorized officers and agents as my agent and attorney in fact, to act for
and in my behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if
executed by me. 
 (f) Exception to Assignments. I understand that the provisions of this Agreement requiring assignment of Inventions
to the Company do not apply to any invention which qualifies fully under the provisions of California Labor Code Section 2870 (attached hereto as Exhibit B). I will advise the Company promptly in writing of any inventions that I believe
meet the criteria in California Labor Code Section 2870 and that are not otherwise disclosed on Exhibit A. 
 4.
Conflicting Employment. I agree that, during the term of my employment with the Company, I will not engage in any other employment, occupation, consulting or other business activity directly related to the business in which the Company
is now involved or becomes involved during the term of my employment, nor will I engage in any other activities that conflict with my obligations to the Company. 

5. Returning Company Documents. I agree that, at the time of leaving the employ of the Company, I will immediately deliver
to the Company (and will not keep in my possession, recreate or deliver to anyone else) any and all devices, records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, equipment, other
documents or property, or reproductions of any aforementioned items developed by me pursuant to my employment with the Company or otherwise belonging to the Company, its successors or assigns. In the event of the termination of my employment, I
agree to sign and deliver the “Termination Certification” attached hereto as Exhibit C. 

  
 -3- 

 6. Notification of New Employer. In the event that I leave the employ of the
Company, I hereby grant consent to notification by the Company to my new employer about my rights and obligations under this Agreement. 
 7.
Solicitation of Employees. I agree that for a period of twelve (12) months immediately following the termination of my relationship with the Company for any reason, whether with or without cause, I shall not either directly
or indirectly solicit, induce, recruit or encourage any of the Company’s employees to leave their employment, or take away such employees, or attempt to solicit, induce, recruit, encourage or take away employees of the Company, either for
myself or for any other person or entity. 
 8. Conflict of Interest Guidelines. I agree to diligently adhere to the
Conflict of Interest Guidelines attached as Exhibit D hereto. 
 9. Representations. I agree to execute any
proper oath or verify any proper document required to carry out the terms of this Agreement. I represent that my performance of all the terms of this Agreement will not breach any agreement to keep in confidence proprietary information acquired by
me in confidence or in trust prior to my employment by the Company. I have not entered into, and I agree I will not enter into, any oral or written agreement in conflict herewith. 

10. Arbitration and Equitable Relief. 

(a) Arbitration. EXCEPT AS PROVIDED IN SECTION 10(b) BELOW, I AGREE THAT ANY DISPUTE OR CONTROVERSY ARISING OUT OF, RELATING TO, OR
CONCERNING ANY INTERPRETATION, CONSTRUCTION, PERFORMANCE OR BREACH OF THIS AGREEMENT SHALL BE SETTLED BY ARBITRATION TO BE HELD IN SANTA CLARA COUNTY, CALIFORNIA, IN ACCORDANCE WITH THE EMPLOYMENT DISPUTE RESOLUTION RULES THEN IN EFFECT OF THE
AMERICAN ARBITRATION ASSOCIATION. THE ARBITRATOR MAY GRANT INJUNCTIONS OR OTHER RELIEF IN SUCH DISPUTE OR CONTROVERSY. THE DECISION OF THE ARBITRATOR SHALL BE FINAL, CONCLUSIVE AND BINDING ON THE PARTIES TO THE ARBITRATION. JUDGMENT MAY BE ENTERED
ON THE ARBITRATOR’S DECISION IN ANY COURT HAVING JURISDICTION. THE COMPANY AND I SHALL EACH PAY ONE-HALF OF THE COSTS AND EXPENSES OF SUCH ARBITRATION, AND EACH OF US SHALL SEPARATELY PAY OUR COUNSEL FEES
AND EXPENSES. 
 THIS ARBITRATION CLAUSE CONSTITUTES A WAIVER OF EMPLOYEE’S RIGHT TO A JURY TRIAL AND RELATES TO THE RESOLUTION OF ALL
DISPUTES RELATING TO ALL ASPECTS OF THE EMPLOYER/EMPLOYEE RELATIONSHIP (EXCEPT AS PROVIDED IN SECTION 10(b) BELOW), INCLUDING, BUT NOT LIMITED TO, THE FOLLOWING CLAIMS: 

  
 -4- 

 i. ANY AND ALL CLAIMS FOR WRONGFUL DISCHARGE OF EMPLOYMENT; BREACH OF CONTRACT, BOTH EXPRESS AND
IMPLIED; BREACH OF THE COVENANT OF GOOD FAITH AND FAIR DEALING, BOTH EXPRESS AND IMPLIED; NEGLIGENT OR INTENTIONAL INFLICTION OF EMOTIONAL DISTRESS; NEGLIGENT OR INTENTIONAL MISREPRESENTATION; NEGLIGENT OR INTENTIONAL INTERFERENCE WITH CONTRACT OR
PROSPECTIVE ECONOMIC ADVANTAGE; AND DEFAMATION; 
 ii. ANY AND ALL CLAIMS FOR VIOLATION OF ANY FEDERAL, STATE OR MUNICIPAL STATUTE,
INCLUDING, BUT NOT LIMITED TO, TITLE VII OF THE CIVIL RIGHTS ACT OF 1964, THE CIVIL RIGHTS ACT OF 1991, THE AGE DISCRIMINATION IN EMPLOYMENT ACT OF 1967, THE AMERICANS WITH DISABILITIES ACT OF 1990, THE FAIR LABOR STANDARDS ACT, THE CALIFORNIA FAIR
EMPLOYMENT AND HOUSING ACT, AND LABOR CODE SECTION 201, et seq.; 
 iii. ANY AND ALL CLAIMS ARISING OUT OF ANY OTHER LAWS AND
REGULATIONS RELATING TO EMPLOYMENT OR EMPLOYMENT DISCRIMINATION. 
 (b) Equitable Remedies. I AGREE THAT IT WOULD BE IMPOSSIBLE OR
INADEQUATE TO MEASURE AND CALCULATE THE COMPANY’S DAMAGES FROM ANY BREACH OF THE COVENANTS SET FORTH IN SECTIONS 2, 3, AND 5 HEREIN. ACCORDINGLY, I AGREE THAT IF I BREACH ANY OF SUCH SECTIONS, THE COMPANY WILL HAVE AVAILABLE, IN ADDITION TO ANY
OTHER RIGHT OR REMEDY AVAILABLE, THE RIGHT TO OBTAIN AN INJUNCTION FROM A COURT OF COMPETENT JURISDICTION RESTRAINING SUCH BREACH OR THREATENED BREACH AND TO SPECIFIC PERFORMANCE OF ANY SUCH PROVISION OF THIS AGREEMENT. I FURTHER AGREE THAT NO BOND
OR OTHER SECURITY SHALL BE REQUIRED IN OBTAINING SUCH EQUITABLE RELIEF AND I HEREBY CONSENT TO THE ISSUANCE OF SUCH INJUNCTION AND TO THE ORDERING OF SPECIFIC PERFORMANCE. 

(c) Consideration. I UNDERSTAND THAT EACH PARTY’S PROMISE TO RESOLVE CLAIMS BY ARBITRATION IN ACCORDANCE WITH THE PROVISIONS OF
THIS AGREEMENT, RATHER THAN THROUGH THE COURTS, IS CONSIDERATION FOR OTHER PARTY’S LIKE PROMISE. I FURTHER UNDERSTAND THAT I AM OFFERED EMPLOYMENT IN CONSIDERATION OF MY PROMISE TO ARBITRATE CLAIMS. 

11. General Provisions. 

(a) Governing Law; Consent to Personal Jurisdiction. This Agreement will be governed by the laws of the State of California without
giving effect to the conflict of laws principles thereof. I hereby expressly consent to the personal jurisdiction of the state and federal courts located in California for any lawsuit filed there against me by the Company arising from or relating to
this Agreement. 

  
 -5- 

 (b) Entire Agreement. This Agreement sets forth the entire agreement and understanding
between the Company and me relating to the subject matter herein and merges all prior discussions between us. No modification of or amendment to this Agreement, nor any waiver of any rights under this agreement, will be effective unless in writing
signed by the party to be charged. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement. 

(c) Severability. If one or more of the provisions in this Agreement are deemed void by law, then the remaining provisions will continue
in full force and effect. 
 (d) Successors and Assigns. This Agreement will be binding upon my heirs, executors, administrators and
other legal representatives and will be for the benefit of the Company, its successors, and its assigns.

INVENTION ON OWN TIME — EXEMPTION 

FROM AGREEMENT 
 (a)
“Any provision in an employment agreement which provides that an employee shall assign, or offer to assign, any of his or her rights in an invention to his or her employer shall not apply to an invention that the employee developed entirely on
his or her own time without using the employer’s equipment, supplies, facilities, or trade secret information except for those inventions that either: 

(1) Relate at the time of conception or reduction to practice of the invention to the employer’s business, or actual or demonstrably
anticipated research or development of the employer; or 
 (2) Result from any work performed by the employee for the employer. 

(b) To the extent a provision in an employment agreement purports to require an employee to assign an invention otherwise excluded from being
required to be assigned under subdivision (a), the provision is against the public policy of this state and is unenforceable.”

ION AMERICA CORPORATION 

CONFLICT OF INTEREST GUIDELINES 

It is the policy of ION AMERICA CORPORATION to conduct its affairs in strict compliance with the letter and spirit of the law and to adhere to
the highest principles of business ethics. Accordingly, all officers, employees and independent contractors must avoid activities which are in conflict, or give the appearance of being in conflict, with these principles and with the interests of the
Company. The following are potentially compromising situations which must be avoided. Any exceptions must be reported to the President and written approval for continuation must be obtained. 

1. Revealing confidential information to outsiders or misusing confidential information. Unauthorized divulging of information is a violation
of this policy whether or not for personal gain and whether or not harm to the Company is intended. (The Employment, Confidential Information, Invention Assignment and Arbitration Agreement elaborates on this principle and is a binding agreement.)

 2. Accepting or offering substantial gifts, excessive entertainment, favors or payments which may be deemed to constitute undue influence
or otherwise be improper or embarrassing to the Company. 
 3. Participating in civic or professional organizations that might involve
divulging confidential information of the Company. 
 4. Initiating or approving personnel actions affecting reward or punishment of
employees or applicants where there is a family relationship or is or appears to be a personal or social involvement. 
 5. Initiating or
approving any form of personal or social harassment of employees. 
 6. Investing or holding outside directorship in suppliers, customers, or
competing companies, including financial speculations, where such investment or directorship might influence in any manner a decision or course of action of the Company. 

7. Borrowing from or lending to employees, customers or suppliers. 

8. Acquiring real estate of interest to the Company. 

9. Improperly using or disclosing to the Company any proprietary information or trade secrets of any former or concurrent employer or other
person or entity with whom obligations of confidentiality exist. 
 10. Unlawfully discussing prices, costs, customers, sales or markets with
competing companies or their employees. 

 11. Making any unlawful agreement with distributors with respect to prices. 

12. Improperly using or authorizing the use of any inventions which are the subject of patent claims of any other person or entity. 

13. Engaging in any conduct which is not in the best interest of the Company. 

Each officer, employee and independent contractor must take every necessary action to ensure compliance with these guidelines and to bring
problem areas to the attention of higher management for review. Violations of this conflict of interest policy may result in discharge without warning.
