QUIDELORTHO CORPORATION 

AMENDED AND RESTATED 1983 EMPLOYEE STOCK PURCHASE PLAN 

(Amended and Restated Effective: May 16, 2022) 

The following constitute the provisions of the 1983 Employee Stock Purchase Plan (herein called the “Plan”) of QuidelOrtho Corporation, a Delaware
corporation (herein called the “Company”). 
 1. Purpose. The purpose of the Plan is to provide employees of the Company and
its Designated Subsidiaries with an opportunity to purchase Common Stock of the Company through accumulated payroll deductions. It is the intention of the Company to have the Plan qualify as an “Employee Stock Purchase Plan” under
Section 423 of the Internal Revenue Code of 1986, as amended. The provisions of the Plan shall, accordingly, be construed so as to extend and limit participation in a manner consistent with the requirements of that section of the Code. 

2. Definitions. 
  

	 	(a)	 “Board” shall mean the Board of Directors of the Company. 

 

	 	(b)	 “Code” shall mean the Internal Revenue Code of 1986, as amended.

from time to time in its sole discretion as eligible to participate in the Plan.

voting shares are held by the Company or a Subsidiary, whether or not such corporation flow exists or is hereafter organized or acquired by the Company or a Subsidiary. 

3. Eligibility. 
 (a) Any Employee as defined in
paragraph 2 who shall be employed by the Company on the date his participation in the Plan is effective shall be eligible to participate in the Plan, subject to limitations imposed by Section 423(b) of the Code. 

(b) Any provisions of the Plan to the contrary notwithstanding, no Employee shall be granted an option under the Plan (i) if, immediately after the
grant, such Employee (or any other person whose stock would be attributed to such Employee pursuant to Section 425(d) of the Code) would own stock and/or hold outstanding options to purchase stock possessing five percent (5%) or more of the
total combined voting power or value of all classes of stock of the Company or of any subsidiary of the Company, or (ii) which permits his rights to purchase stock under all employee stock purchase plans of the Company and its subsidiaries to
accrue at a rate which exceeds Twenty Five Thousand Dollars ($25,000) of fair market value of such stock (determined at the time such option is granted) for each calendar year in which such option is outstanding at any time. 

4. Offering Periods. The Plan shall be implemented by one offering during each six month period of the Plan, commencing on or about, and
continuing thereafter until terminated in accordance with paragraph 19 hereof. The Board of Directors of the Company shall have the power to change the duration of offering periods with respect to future offerings without stockholder approval if
such change is announced at least fifteen (15) days prior to the scheduled beginning at the first offering period to be affected. 

 5. Participation. 

(a) An eligible Employee may become a participant in the Plan by completing a subscription agreement authorizing payroll deduction on the form provided by the
Company and filing it with the Company’s payroll office prior to the applicable Offering Date, unless a later time for filing the subscription agreement is set by the Board for all eligible employees with respect to a given offering. 

(b) Payroll deductions for a participant shall commence on the first payroll following the Offering Date and shall end on the Exercise Date of the offering to
which such authorization is applicable, unless sooner terminated by the participant as provided in paragraph 10. 
 6. Payroll Deductions.

 (a) At the time a participant files his subscription agreement, he shall elect to have payroll deductions made on each payday during the offering period
in an amount not exceeding ten percent (10%) of the Compensation which he received on the payday immediately preceding the Offering Date, and the aggregate of such payroll deductions during the offering period shall not exceed ten percent (10%) of
his aggregate Compensation during said offering period. 
 (b) All payroll deductions made by a participant shall be credited to his account under the Plan.
A participant may not make any additional payments into such account. 
 (c) A participant may discontinue his participation in the Plan as provided in
paragraph 10, or may lower, but not increase, the rate of his payroll deductions during the offering period by completing or filing with the Company a new authorization for payroll deduction. The change in rate shall be effective fifteen
(15) days following the Company’s receipt of the new authorization. 
 7. Grant of Option.  

(a) On the Offering Date of each six month offering period, each eligible Employee participating in the Plan shall be granted an option to purchase (at the per
share option price) up to a number of shares of the Company’s Common Stock determined by dividing such Employee’s payroll deductions to be accumulated during such offering period (not to exceed an amount equal to ten percent (10%) of his
Compensation as of the date of the commencement of the applicable offering period) by eighty-five percent (85%) of the fair market value of a share of the Company’s Common Stock on the Offering Date, subject to the limitations set forth in
Section 3(b) and 12 hereof. Fair market value of a share of the Company’s Common Stock shall be determined as provided in Section 7(b) herein. Notwithstanding the foregoing, no employee shall be granted an option to purchase more than
5,000 shares of the Company’s Common Stock during any six-month offering period. 
 (b) The option price per
share of the shares offered in a given offering period shall be the lower of: (i) 85% of the fair market value of a share of the Common Stock of the Company on the Offering Date; or (ii) 85% of the fair market value of a share of the Common Stock of
the Company on the Exercise Date. The fair market value of the Company’s Common Stock on a given date shall be the mean of the reported bid and asked prices for that date except that the fair market value on the Offering Date of the initial
offering period shall be the initial public offering price. 
 8. Exercise of Option. Unless a participant withdraws from the Plan as provided
in paragraph 10, his option for the purchase of shares will be exercised automatically on the Exercise Date of the offering period, and the maximum number of full shares subject to option will be purchased for him at the applicable option price with
the accumulated payroll deductions in his account. If the total amount of payroll deductions for a participant during the offering period exceeds the purchase price of such shares as determined in Section 7(a), such excess amount will be
refunded to the participant. 
 9. Delivery. As promptly as practicable after the Exercise Date of each offering, the Company shall arrange
the delivery to each participant, as appropriate, of a certificate representing the shares purchased upon exercise of his option. 

 Any cash remaining to the credit of a participant’s account under the Plan after a purchase by him of
shares at the termination of each offering period, or which is insufficient to purchase a full share of Common Stock of the Company, shall be returned to said participant. 

10. Withdrawal; Termination of Employment. 
 (a) A
participant may withdraw all but not less than all the payroll deductions credited to his account under the Plan up to one week prior to the Exercise Date of the offering period by giving written notice to the Company. All of the participant’s
payroll deductions credited to his account will be paid to him promptly after receipt of his notice of withdrawal and his option for the current period will be automatically terminated, and no further payroll deductions for the purchase of shares
will be made during the offering period. 
 (b) Upon termination of the participant’s employment prior to the Exercise Date of the offering period for
any reason, including retirement or death, the payroll deductions credited to his account will be returned to him or, in the case of his death, to the person or persons entitled thereto under paragraph 14, and his option will be automatically
terminated. 
 (c) in the event an Employee fails to remain in the continuous employ of the Company for at least twenty (20) hours per week during the
offering period in which the employee is a participant, he will be deemed to have elected to withdraw from the Plan and the payroll deductions credited to his account will be returned to him and his option terminated. 

(d) A participant’s withdrawal from an offering will not have any effect upon his eligibility to participate in a succeeding offering or in any similar
plan which may hereafter be adopted by the Company. 
 11. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan. 
 12. Stock. 
 (a) The
maximum number of shares of the Company’s Common Stock that shall be made available for sale under the Plan shall be 2,250,000 shares, subject to adjustment upon changes in capitalization of the Company as provided in paragraph 18. If the total
number of shares which would otherwise be subject to options granted pursuant to Section 7(a) hereof on the Offering Date of an offering period exceeds the number of shares then available under the Plan (after deduction of all shares for which
options have been exercised or are then outstanding), the Company shall make a pro rata allocation of the shares remaining available for option grant in as uniform a manner as shall be practicable and as it shall determine to be equitable. In such
event, the Company shall give written notice of such reduction of the number of shares subject to the option to each Employee affected thereby and shall similarly reduce the rate of payroll deductions, if necessary. 

(b) The participant will have no interest or voting right in shares covered by his option until such option has been exercised. 

(c) Shares to be delivered to a participant under the Plan will be registered in the name of the participant or in the name of the participant and his spouse.

 13. Administration. The Plan shall be administered by the Board of Directors of the Company or a committee appointed by the Board.
The administration, interpretation or application of the Plan by the Board or its committee shall be final, conclusive and binding upon all participants. Members of the Board who are eligible Employees are permitted to participate in the Plan,
provided that: 
 (a) Members of the Board who are eligible to participate in the Plan may not vote on any matter affecting the administration of the Plan
or the grant of any option pursuant to the Plan. 
 (b) If a committee is established to administer the Plan, no member of the Board who is eligible to
participate in the Plan may be a member of the committee. 

 14. Designation of Beneficiary. 

(a) A participant may file a written designation of a beneficiary who is to receive any shares and cash, if any, from the participant’s account under the
Plan in the event of such participant’s death subsequent to the end of the offering period but prior to delivery to him of such shares and cash. In addition, a participant may file a written designation of a beneficiary who is to receive any
cash from the participant’s account under the Plan in the event of such participant’s death prior to the Exercise Date of the offering period. 

(b) Such designation of beneficiary may be changed by the participant at any time by written notice. In the event of the death of a participant and in the
absence of a beneficiary validly designated under the Plan who is living at the time of such participant’s death, the Company shall deliver such shares and/or cash to the executor or administrator of the estate of the participant, or if no such
executor or administrator has been appointed (to the knowledge of the Company), the Company, in its discretion, may deliver such shares and/or cash to the spouse or to any one or more dependents or relatives of the participant, or if no spouse,
dependent or relative is known to the Company, then to such other person as the Company may designate. 
 15. Transferability. Neither
payroll deductions credited to a participant’s account nor any rights with regard to the exercise of an option or to receive shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will,
the laws of descent and distribution or as provided in paragraph 14 hereof) by the participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Company may treat such act as an election
to withdraw funds in accordance with paragraph 10. 
 16. Use of Funds. All payroll deductions received or held by the Company under
the Plan may be used by the Company for any corporate purpose, and the Company shall not be obligated to segregate such payroll deductions. 
 17.
Reports. Individual accounts will be maintained for each participant in the Plan. Statements of account will be given to participating Employees semi-annually promptly following the Exercise Date, which statements will set forth
the amounts of payroll deductions, the per share purchase price, the number of shares purchased and the remaining cash balance, if any. 
 18.
Adjustments Upon Changes in Capitalization. Subject to any required action by the stockholders of the Company, the number of shares of Common Stock covered by each option under the Plan which has not yet been exercised and the
number of shares of Common Stock which have been authorized for issuance under the Plan but have not yet been placed under option (collectively, the “Reserves”), as well as the price per share of Common Stock covered by each option under
the Plan which has not yet been exercised, shall be proportionately adjusted for any increase or decrease in the number of issued shares of Common Stock resulting from a stock split or the payment of a stock dividend (but only on the Common Stock)
or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been
“effected without receipt of consideration”. Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issue by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of shares of Common Stock subject to an option. 

The Board may, if it so determines in the exercise of its sole discretion, also make provision for adjusting the Reserves, as well as the price per share of
Common Stock covered by each outstanding option, in the event that the Company effects one or more reorganizations, recapitalizations, rights offerings or other increases or reductions of shares of its outstanding Common Stock, and in the event of
the Company being consolidated with or merged into any other corporation. 
 19. Amendment or Termination. The Board of Directors of
the Company may at any time terminate or amend the Plan. No such termination can affect options previously granted, nor may an amendment make any change in any option theretofore granted which adversely affects the rights of any participant, nor may
an amendment be made without prior approval of the stockholders of the Company if such amendment would: 
 (a) increase the number of shares that may be
issued under the Plan; 

 (b) Permit payroll deductions at a rate in excess of ten percent (10%) of the participant’s
Compensation; 
 (c) Modify the requirements concerning which employees (or class of employees) are eligible for participation in the Plan; or 

(d) Materially increase the benefits which may accrue to participants under the Plan. 

20. Notices. All notices or other communications by a participant to the Company under or in connection with the Plan shall be deemed to
have been duly given when received in the form specified by the Company at the location, or by the person, designated by the Company for the receipt thereof. 

21. Stockholder Approval. Continuance of the Plan shall be subject to approval by the stockholders of the Company within twelve months
before or after the date the Plan is adopted. If such share- holder approval is obtained at a duly held stockholders’ meeting, it may be obtained by the affirmative vote of the holders of a majority of the outstanding shares of the Company
present or represented and entitled to vote thereon, which approval shall be: 
 (a) (1) solicited substantially in accordance with Section 14(a)
of the Securities Act of 1934, as amended (the “Act”) and the rules and regulations promulgated thereunder, or (2) solicited after the Company has furnished in writing to the holders entitled to vote substantially the same information
concerning the Plan as that which would be required by the rules and regulations in effect under Section 14(a) of the Act at the time such information is furnished; and 

(b) obtained at or prior to the first annual meeting of stockholders held subsequent to the first registration of Common Stock under Section 12 of the
Act. 
 In the case of approval by written consent, it must be obtained by the unanimous written consent of all stockholders of the Company. 

22. Conditions Upon Issuance of Shares. Shares shall not be issued with respect to an option unless the exercise of such option and the
issuance and delivery of such shares pursuant thereto shall comply with all applicable provisions of law, domestic or foreign, including, without limitation, the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended,
the rules and regulations promulgated thereunder, and the requirements of any stock exchange upon which the shares may then be listed, and shall be further subject to the approval of counsel for the Company with respect to such compliance. 

As a condition to the exercise of an option, the Company may require the person exercising such option to represent and war rant at the time of any such
exercise that the shares are being purchased only for investment and without any present intention to sell or distribute such shares if, in the opinion of counsel for the Company, such a representation is required by any of the aforementioned
applicable provisions of law.EX-10.10

 EXHIBIT 10.10 

INDEMNIFICATION AGREEMENT 

This Indemnification Agreement (this “Agreement”) is made as of this day of
             , 20 ,     by and between QuidelOrtho Corporation, a Delaware corporation (the “Company”) and
(“Indemnitee”). 
 RECITALS 

WHEREAS, the Board of Directors of the Company (the “Board of Directors”) has determined that in order to attract and
retain qualified persons as directors and officers of the Company, it is in the best interests of the Company and its stockholders to assure such persons that there will be adequate certainty of protection through insurance and indemnification
against risks of claims and actions against them arising out of their service to, and activities on behalf of, the Company; and 
 WHEREAS,
the Company has adopted provisions in its By-laws providing for indemnification of certain officers and its directors to the fullest extent permitted by the Delaware General Corporation Law (the
“DGCL”), and the Company wishes to clarify and detail the rights and obligations of the Company and Indemnitee with respect to indemnification; and 

WHEREAS, in order to induce and encourage highly experienced and capable persons, such as Indemnitee, to serve and continue to serve as
directors and officers of the Company and in any other capacity with respect to the Company, and to otherwise promote the desirable end that such persons will resist what they consider unjustified lawsuits and claims made against them in connection
with the good faith performance of their duties to the Company, with the knowledge that certain costs, judgments, penalties, fines, liabilities and expenses incurred by them in their defense of such lawsuits and claims are to be borne by the Company
and they will receive the appropriate protection against such risks and liabilities, the Board of Directors has determined that this Agreement is reasonable and prudent to promote and ensure the best interests of the Company and its stockholders;
and 
 WHEREAS, the Company desires to have Indemnitee serve and/or continue to serve as a director and/or officer of the Company and in
such other capacity with respect to the Company as the Company may request, as the case may be, free from undue concern for unpredictable, inappropriate or unreasonable legal risks and personal liabilities by reason of Indemnitee acting in good
faith in the performance of Indemnitee’s duty to the Company; and 
 WHEREAS, Indemnitee desires to serve and/or continue to serve the
Company, provided, and on the express condition, that he or she is furnished with the indemnity protections set forth hereinafter. 
 Now,
therefore, in consideration of Indemnitee’s service and/or continued service as a director and/or officer of the Company, the parties hereto agree as follows: 

AGREEMENT 
  

	1.	 Service by Indemnitee. Indemnitee will serve and/or continue to serve as a director and/or officer of
the Company faithfully and to the best of Indemnitee’s ability so long as Indemnitee is duly elected or appointed and until such time as Indemnitee is removed as permitted by law or tenders a resignation in writing. This Agreement does not
create any obligation on the Company to continue to engage Indemnitee in such position and is not an employment contract between the Company and Indemnitee. 

	2.	 Indemnification. The Company shall indemnify Indemnitee to the fullest extent permitted by the DGCL in
effect on the date hereof or as such law may be amended from time to time (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than such law permitted the
Company to provide prior to such amendment), all on the terms and conditions set forth in this Agreement. Without diminishing the scope of the indemnification provided by this Section, the rights of indemnification of Indemnitee provided hereunder
shall include, but shall not be limited to, those rights hereinafter set forth, except that no indemnification shall be paid to Indemnitee: 

(a) for which payment is actually made to Indemnitee under a valid and collectible insurance policy or under a valid and enforceable indemnity
clause, by-law or agreement of the Company or any other company or organization, except in respect of any indemnity exceeding the payment under such insurance, clause,
by-law or agreement (and Indemnitee shall reimburse the Company for any amounts paid by the Company and subsequently so recovered by Indemnitee); 

(b) in connection with an action, suit or proceeding, or part thereof initiated or brought voluntarily by Indemnitee (including claims and
counterclaims, whether such counterclaims are asserted by (i) Indemnitee or (ii) the Company in an action, suit or proceeding initiated by Indemnitee) and not by way of defense, except a judicial proceeding or arbitration pursuant to
Section 11 to enforce rights under this Agreement, unless the action, suit or proceeding (or part thereof) was authorized or ratified by the Board of Directors; 

(c) on account of Indemnitee’s conduct which is finally adjudged to have been knowingly fraudulent or deliberately dishonest, or to
constitute willful misconduct; 
 (d) on account of any suit in which judgment is rendered against Indemnitee for an accounting of profits
made for the purchase or sale by Indemnitee of securities of the Company pursuant to Section 16(b) of the Securities Exchange Act of 1934, as amended (the “Securities Exchange Act”), or any similar successor statute;

 (e) for any reimbursement of the Company by Indemnitee of any compensation pursuant to Section 304 of the Sarbanes-Oxley Act of 2002
or any compensation recoupment under a clawback policy adopted by the Board of Directors or the compensation committee of the Board of Directors; 

(f) with respect to any action, suit or proceeding brought by or on behalf of the Company against Indemnitee that is authorized by the Board of
Directors, except as provided in Sections 5 and 6 below and the exception to the proviso in Section 4 below; and 
 (g) if a final
decision by a court having competent jurisdiction in the matter shall determine that such indemnification is not lawful. 
  

	3.	 Action or Proceedings Other than an Action by or in the Right of the Company. Except as limited by
Section 2 above, Indemnitee shall be entitled to the indemnification rights provided in this Section if Indemnitee was or is a party, or is threatened to be made a party, to any Proceeding (defined below) (other than an action by or in the
right of the Company) by reason of the fact that Indemnitee is or was a director, officer, employee, agent or fiduciary of the Company, or while a director, officer, employee, agent or fiduciary of the Company is or was serving at the request of the
Company as a director, officer, employee, agent or fiduciary of any other entity (including, but not limited to, another corporation, partnership, joint venture, trust or employee benefit plan); or by reason of anything done or not done by
Indemnitee in any such capacity. Pursuant to this 

  
 2 

	 	
Section, Indemnitee shall be indemnified against all costs, judgments, penalties, fines, liabilities, amounts paid in settlement by or on behalf of Indemnitee, and Expenses (defined below)
(including all reasonable interest, assessments and other charges paid or payable in connection with or in respect of such costs, judgments, penalties, fines, liabilities, amounts paid in settlement and Expenses) actually and reasonably incurred by
Indemnitee or on Indemnitee’s behalf in connection with such Proceeding, if Indemnitee acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the Company, and with respect to any
criminal Proceeding, had no reasonable cause to believe his or her conduct was unlawful. 

  

	4.	 Indemnity in Proceedings by or in the Right of the Company. Except as limited by Section 2 above,
Indemnitee shall be entitled to the indemnification rights provided in this Section if Indemnitee was or is a party, or is threatened to be made a party, to any Proceeding brought by or in the right of the Company to procure a judgment in its favor
by reason of the fact that Indemnitee is or was a director, officer, employee, agent or fiduciary of the Company, or while a director, officer, employee, agent or fiduciary of the Company is or was serving at the request of the Company as a
director, officer, employee or agent or fiduciary of any other entity (including, but not limited to, another corporation, partnership, joint venture, trust or employee benefit plan); or by reason of anything done or not done by Indemnitee in any
such capacity. Pursuant to this Section, Indemnitee shall be indemnified against all costs, judgments, penalties, fines, liabilities, amounts paid in settlement by or on behalf of Indemnitee, and Expenses including all reasonable interest,
assessments and other charges paid or payable in connection with or in respect of such costs, judgments, penalties, fines, liabilities, amounts paid in settlement and Expenses actually and reasonably incurred by Indemnitee in connection with such
Proceeding if Indemnitee acted in good faith and in a manner Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, that no such indemnification shall be made in respect of any
Proceeding as to which Delaware law expressly prohibits such indemnification by reason of any adjudication of liability of Indemnitee to the Company, unless and only to the extent that the Court of Chancery of the State of Delaware or the court in
which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, Indemnitee is entitled to indemnification for such costs, judgments, penalties,
fines, liabilities and Expenses as such court shall deem proper. 

  

	5.	 Indemnification for Costs, Charges and Expenses of Successful Party. Notwithstanding the limitations of
Section 2(b), 2(f), 3 and 4 above, to the extent that Indemnitee has been successful, on the merits or otherwise, in whole or in part, in defense of any Proceeding or in defense of any claim, issue or matter therein, including, without
limitation, the dismissal of any action without prejudice, or if it is ultimately determined, by final judicial decision of a court of competent jurisdiction from which there is no further right to appeal, that Indemnitee is otherwise entitled to be
indemnified against Expenses, Indemnitee shall be indemnified against all Expenses actually and reasonably incurred in connection therewith. 

  

	6.	 Partial Indemnification. If Indemnitee is entitled under any provision of this Agreement to
indemnification by the Company for some or a portion of the costs, judgments, penalties, fines, liabilities or Expenses actually and reasonably incurred in connection with any action, suit or proceeding (including an action, suit or proceeding
brought by or on behalf of the Company), but not, however, for all of the total amount thereof, the Company shall nevertheless indemnify Indemnitee for the portion of such costs, judgments, penalties, fines, liabilities and Expenses actually and
reasonably incurred to which Indemnitee is entitled. 

  
 3 

	7.	 Contribution. If the indemnification provided in Sections 3, 4 and 6 above is unavailable and may not be
paid to Indemnitee for any reason (other than those set forth in Section 2(a)-(g)), then with respect to any Proceeding in which the Company is jointly liable with Indemnitee (or would be if joined in such Proceeding), the Company shall
contribute to the amount of Expenses, judgments, penalties, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee to the fullest extent allowed by applicable law, in such proportion as is appropriate
to reflect (i) the relative benefits received by the Company, on the one hand, and by the Indemnitee, on the other hand, from the transaction from which such Proceeding arose and (ii) the relative fault of the Company, on the one hand, and
the Indemnitee, on the other hand, in connection with the events which resulted in such Expenses, judgments, penalties, fines or settlement amounts, as well as any other relevant equitable considerations. The relative fault of the Company, on the
one hand, and of the Indemnitee, on the other hand, shall be determined by reference to, among other matters, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent the circumstances resulting in
such Expenses, judgments, penalties, fines or settlement amounts. The Company agrees that it would not be just and equitable if contribution pursuant to this Section 7 were determined by pro rata allocation or any other method of allocation
which does not take into account the foregoing equitable considerations. 

  

	8.	 Indemnification for Expenses of a Witness. Notwithstanding any other provision of this Agreement, to the
maximum extent permitted by applicable law, Indemnitee shall be entitled to indemnification against all Expenses actually and reasonably incurred or suffered by Indemnitee or on Indemnitee’s behalf if Indemnitee appears as a witness or
otherwise incurs legal expenses as a result of, or related to, Indemnitee’s service as a director, officer, employee, agent or fiduciary of the Company or, at the request of the Company, of any other entity, in any threatened, pending or
completed legal, administrative, investigative or other proceeding or matter to which Indemnitee neither is, nor is threatened to be made, a party. 

  

	9.	 Determination of Entitlement to Indemnification. 

(a) To receive indemnification under this Agreement, Indemnitee shall submit a written request to the General Counsel of the Company (or, if
there is no General Counsel, or if Indemnitee is the General Counsel, the President of the Company). Such request shall include documentation or information which is reasonably necessary for the determination of the right to indemnification and
which is reasonably available to Indemnitee. 
 (b) Upon written request by Indemnitee for indemnification pursuant to Sections 3, 4, 5, 6 or
8, the entitlement of Indemnitee to indemnification, to the extent not provided pursuant to the terms of this Agreement, shall be determined by the following person or persons as selected by the Board of Directors who shall be empowered to make such
determination (except in the case of (iii), which may be selected by the Disinterested Directors or (v), which shall be the default selection under this clause (b) after a Change in Control (defined below) has occurred): (i) the Board of
Directors by a majority vote of Disinterested Directors (defined below), whether or not such majority constitutes a quorum; (ii) a committee of Disinterested Directors designated by a majority vote of such Disinterested Directors, whether or
not such majority constitutes a quorum; (iii) if there are no Disinterested Directors, or if the Disinterested Directors so direct, by Independent Counsel (defined below) in a written opinion to the Board of Directors, a copy of which shall be
delivered to Indemnitee; (iv) the stockholders of the Company; or (v) in the event a Change in Control has occurred, solely by Independent Counsel in a written opinion to the Board of Directors, a copy of which shall be delivered to
Indemnitee. If the person, persons or entity making such determination shall determine that Indemnitee is entitled to indemnification as to part (but not all) of any application for indemnification, such person shall reasonably prorate such partial
indemnification among the claims, issues or matters at issue at the time of the determination. 

  
 4 

 (c) If the determination of entitlement to indemnification is to be made by Independent
Counsel pursuant to Section 9(b) hereof, the Independent Counsel shall be selected as provided in this Section 9(c). If a Change in Control has occurred, the Independent Counsel shall be selected by Indemnitee (unless Indemnitee requests
such selection be made by the Board of Directors), and Indemnitee shall give written notice to the Company advising the Company of the identity of the Independent Counsel so selected. Otherwise, the Independent Counsel shall be selected by the Board
of Directors, or if selected under clause (b)(iii) above, the Disinterested Directors, and the Company shall give written notice to Indemnitee advising Indemnitee of the identity of the Independent Counsel so selected. In either event, Indemnitee or
the Company, as the case may be, may, within seven (7) days after receipt of such notice of selection, deliver to the Company or Indemnitee, as the case may be, a written objection to such selection; provided, however, such
objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of “Independent Counsel” as defined in Section 19(g) of this Agreement, and the objection shall set forth with
particularity the factual basis of such assertion. Absent a proper and timely objection, the person so selected shall act as Independent Counsel. If a written objection is made and substantiated, the Independent Counsel selected may not serve as
Independent Counsel unless and until such objection is withdrawn or a court has determined that such objection is without merit. If, within twenty (20) days after submission by Indemnitee of a written request for indemnification pursuant to
Section 9(a) hereof, (i) an Independent Counsel has not been selected by the Company, if applicable, or (ii) an Independent Counsel has been selected but there is an outstanding written objection regarding the qualification of the
Independent Counsel, either Indemnitee or the Company may petition a court of competent jurisdiction for resolution of any objection which shall have been made by Indemnitee or the Company to the other’s selection of Independent Counsel and/or
for the appointment as Independent Counsel of a person selected by the court or by such other person as the court shall designate, and the person with respect to whom all objections are so resolved or the person so appointed shall act as Independent
Counsel under Section 9(b) hereof. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred by such Independent Counsel in connection with acting pursuant to Section 9(b) hereof, and the Company shall
pay all reasonable fees and expenses incident to the procedures of this Section 9(c), regardless of the manner in which such Independent Counsel was selected or appointed. 

(d) Any Expenses incurred by Indemnitee in connection with a request for indemnification or payment of Expenses hereunder, under any other
agreement, any provision of the Company’s By-laws or any directors’ and officers’ liability insurance, shall be borne by the Company. The Company hereby indemnifies Indemnitee for any such
Expenses and agrees to hold Indemnitee harmless therefrom irrespective of the outcome of the determination of Indemnitee’s entitlement to indemnification. 
  

	10.	 Presumptions and Effect of Certain Proceedings. 

(a) The General Counsel of the Company (or if there is no General Counsel, or if Indemnitee is the General Counsel, the President of the
Company) shall, promptly upon receipt of Indemnitee’s written request for indemnification, advise in writing the Board of Directors or such other person, persons or entity empowered or selected to make the determination as provided in
Section 9 that Indemnitee has made such request for indemnification. Upon making such request for indemnification, Indemnitee shall be presumed to be entitled to indemnification hereunder and the Company shall have the burden of proof to
overcome that presumption in connection with the making by any person, persons or entity of any determination contrary to such presumption. 

  
 5 

 (b) If the person, persons or entity so empowered to make such determination shall have
failed to make the requested determination with respect to indemnification within forty-five (45) days after receipt by the General Counsel of the Company (or if there is no General Counsel, or if Indemnitee is the General Counsel, the
President of the Company) of such request, a requisite determination of entitlement to indemnification shall be deemed to have been made and Indemnitee shall be entitled to such indemnification, absent (i) a misstatement by Indemnitee of a
material fact, or an omission of a material fact necessary to make Indemnitee’s statement not materially misleading, in connection with the request for indemnification or (ii) a prohibition of such indemnification under applicable law;
provided, however, that such 45-day period may be extended for a reasonable period of time, not to exceed an additional thirty (30) days, if the person, persons or entity making the
determination with respect to entitlement to indemnification in good faith requires such additional time for obtaining or evaluating documentation and/or information relating thereto; and provided, further, that the foregoing
provisions of this Section 10(b) shall not apply: (i)(A) if the determination of entitlement to indemnification is to be made by the stockholders pursuant to Section 9(b) of this Agreement and (B)(1) if, within fifteen (15) days after
receipt by the General Counsel of the Company (or if there is no General Counsel, or if Indemnitee is the General Counsel, the President of the Company) of the request for such determination, the Board of Directors or the Disinterested Directors, if
appropriate, resolve to submit such determination to the stockholders for their consideration at an annual meeting thereof to be held within seventy-five (75) days after such receipt and such determination is made thereat or (2) a special
meeting of stockholders is called within thirty (30) days after such receipt for the purpose of making such determination, such meeting is held for such purpose within sixty (60) days after having been so called and such determination is
made thereat; or (ii) if the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to Section 9(b) of this Agreement. 

(c) The termination of any Proceeding described in Sections 3 or 4 by judgment, order, settlement or conviction, or upon a plea of nolo
contendere or its equivalent, shall not, of itself: (i) create a presumption that Indemnitee did not act in good faith and in a manner which Indemnitee reasonably believed to be in or not opposed to the best interests of the Company, or,
with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that Indemnitee’s conduct was unlawful; or (ii) otherwise adversely affect the rights of Indemnitee to indemnification except as may be provided
herein. 
  

	11.	 Remedies of Indemnitee in Cases of Determination not to Indemnify or to Advance Expenses. In the event
that a determination is made that Indemnitee is not entitled to indemnification hereunder or if payment has not been timely made following a determination of entitlement to indemnification pursuant to Sections 9 and 10, or if advancement of Expenses
is not timely made pursuant to Section 16, Indemnitee shall at any time thereafter be entitled to seek an adjudication of entitlement to such indemnification or advancement of Expenses, and any such suit shall be brought in the Court of
Chancery of the State of Delaware, unless otherwise required by the laws of the state in which Indemnitee primarily resides and works. Alternatively, Indemnitee, at Indemnitee’s option, may seek an award in an arbitration to be conducted by a
single arbitrator pursuant to the Commercial Arbitration Rules of the American Arbitration Association, such award to be made within sixty (60) days following the filing of the demand for arbitration, and judgment on the award rendered by the
arbitrator may be entered in any court having jurisdiction thereof. The Company shall not oppose Indemnitee’s right to seek any such adjudication or award in arbitration or any other claim hereunder. In any suit or arbitration brought by
Indemnitee to 

  
 6 

	 	
enforce a right to indemnification hereunder (but not in a suit or arbitration brought by the Indemnitee to enforce a right to an advancement of Expenses), it shall be a defense that Indemnitee
has not met any applicable standard of conduct for indemnification set forth in the DGCL, including the standard described in Section 3 or 4, as applicable, or that Indemnitee is not entitled to be indemnified because such indemnification is
excluded under Section 2(a)-(g) of this Agreement. Further, in any suit brought by the Company to recover an advancement of Expenses pursuant to the terms of an undertaking, the Company shall be entitled to recover such Expenses upon a final
judicial decision of a court of competent jurisdiction from which there is no further right to appeal that the Indemnitee has not met the standard of conduct described above. The determination in any such judicial proceeding or arbitration shall be
made de novo and Indemnitee shall not be prejudiced by reason of a determination (if so made) pursuant to Sections 9 or 10 that Indemnitee is not entitled to indemnification. If a determination is made or deemed to have been made pursuant to
the terms of Section 9 or 10 that Indemnitee is entitled to indemnification, the Company shall be bound by such determination, absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make
Indemnitee’s statement not materially misleading, in connection with the request for indemnification or (ii) a prohibition of such indemnification under applicable law. In addition, if a determination is made or deemed to have been made
pursuant to the terms of Section 9 or 10 that Indemnitee is entitled to indemnification, the Company shall be precluded from asserting that such determination has not been made or that the procedure by which such determination was made is not
valid, binding and enforceable. The Company further agrees to stipulate in any such court or before any such arbitrator that the Company is bound by all the provisions of this Agreement and is precluded from making any assertions to the contrary. If
the court or arbitrator shall determine that Indemnitee is entitled to any indemnification or advancement of Expenses hereunder, the Company shall pay all Expenses actually and reasonably incurred by Indemnitee in connection with such adjudication
or award in arbitration (including, but not limited to, any appellate Proceedings), and in any suit brought by the Company to recover an advancement of Expenses pursuant to the terms of an undertaking, the Company shall pay all Expenses actually and
reasonably incurred by Indemnitee in connection with such suit to the extent the Indemnitee has been successful, on the merits or otherwise, in whole or in part, in defense of such suit, to the fullest extent permitted by law. 

 

	12.	 Non-Exclusivity of Rights. 

(a) Indemnification and advancement of Expenses provided by this Agreement shall not be deemed exclusive of any other rights to which
Indemnitee may now or in the future be entitled under any provision of the By-laws or other organizational documents of the Company, vote of stockholders of the Company or Disinterested Directors, provision of
law, agreement or otherwise. 
 [(b) The Company hereby acknowledges that Indemnitee may have certain rights to indemnification, advancement
of Expenses and/or insurance provided by one or more other persons with whom or which Indemnitee may be associated (including, without limitation, any Designating Stockholder). The relationship between the Company and such other persons, other than
an Enterprise, with respect to the Indemnitee’s rights to indemnification, advancement of Expenses, and insurance is described by 

  
 7 

 
this subsection, subject to the provisions of subsection (f) of this Section 12 with respect to a Proceeding concerning Indemnitee’s Corporate Status with an
Enterprise. The Company hereby acknowledges and agrees that, in connection with any Proceeding: 
  

	 	(i)	 the Company’s obligations to Indemnitee are primary and any obligation of any other persons, other than an
Enterprise, are secondary (i.e., the Company is the indemnitor of first resort) with respect to any request for indemnification or advancement of Expenses made pursuant to this Agreement concerning any Proceeding; 

 

	 	(ii)	 the Company is primarily liable for all indemnification and indemnification or advancement of Expenses
obligations for any Proceeding, whether created by law, organizational or constituent documents, contract (including this Agreement) or otherwise; 

  

	 	(iii)	 any obligation of any other persons with whom or which Indemnitee may be associated (including, without
limitation, any Designating Stockholder) to indemnify Indemnitee and/or advance Expenses to Indemnitee in respect of any proceeding are secondary to the obligations of the Company’s obligations; and 

 

	 	(iv)	 the Company will indemnify Indemnitee and advance Expenses to Indemnitee hereunder to the fullest extent
provided herein without regard to any rights Indemnitee may have against any other person with whom or which Indemnitee may be associated (including, any Designating Stockholder) or insurer of any such person; and 

(c) The Company irrevocably waives, relinquishes and releases (i) any other person with whom or which Indemnitee may be associated
(including, without limitation, any Designating Stockholder) from any claim of contribution, subrogation, reimbursement, exoneration or indemnification, or any other recovery of any kind in respect of amounts paid by the Company to Indemnitee
pursuant to this Agreement and (ii) any right to participate in any claim or remedy of Indemnitee against any person (including, without limitation, any Designating Stockholder), whether or not such claim, remedy or right arises in equity or
under contract, statute or common law, including, without limitation, the right to take or receive from any person (including, without limitation, any Designating Stockholder), directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim, remedy or right. 
 (d) In
the event any other person with whom or which Indemnitee may be associated (including, without limitation, any Designating Stockholder) or their insurers advances or extinguishes any liability or loss for Indemnitee, the payor has a right of
subrogation against the Company or its insurers for all amounts so paid which would otherwise be payable by the Company or its insurers under this Agreement. In no event will payment by any other person with whom or which Indemnitee may be
associated (including, without limitation, any Designating Stockholder) or their insurers affect the obligations of the Company hereunder or shift primary liability for the Company’s obligation to indemnify or advance Expenses to any other
person with whom or which Indemnitee may be associated (including, without limitation, any Designating Stockholder). 
 (e) Any
indemnification or advancement of Expenses provided by any other person with whom or which Indemnitee may be associated (including, without limitation, any Designating Stockholder) is specifically in excess over the Company’s obligation to
indemnify and advance Expenses or any valid and collectible insurance (including, but not limited to, any malpractice insurance or professional errors and omissions insurance) provided by the Company. 

  
 8 

 (f) The Company’s obligation to indemnify or advance Expenses hereunder to Indemnitee
for any Proceeding concerning Indemnitee’s Corporate Status with an Enterprise will be reduced by any amount Indemnitee has actually received as indemnification or advancement of Expenses from such Enterprise. The Company and Indemnitee intend
that any such Enterprise (and its insurers) be the indemnitor of first resort with respect to indemnification and advancement of Expenses for any Proceeding related to or arising from Indemnitee’s Corporate Status with such Enterprise. The
Company’s obligation to indemnify and advance Expenses to Indemnitee is secondary to the obligations the Enterprise or its insurers owe to Indemnitee. Indemnitee agrees to take all reasonably necessary and desirable action to obtain from an
Enterprise indemnification and advancement of Expenses for any Proceeding related to or arising from Indemnitee’s Corporate Status with such Enterprise. 

(g) The Company and Indemnitee agree that the Designating Stockholder is an intended third-party beneficiary of this Section 12.]1 
  

	13.	 Expenses to Enforce Agreement. In the event that Indemnitee is subject to, or intervenes in, any
Proceeding in which the validity or enforceability of this Agreement is at issue or seeks an adjudication or award in arbitration to enforce Indemnitee’s rights under, or to recover damages for breach of, this Agreement, Indemnitee, if
Indemnitee prevails in whole or in part in such action, shall be entitled to recover from the Company and shall be indemnified by the Company against any actual Expenses incurred by Indemnitee in connection with such action. 

 

	14.	 Continuation of Indemnity. All agreements and obligations of the Company contained herein shall continue
during the period Indemnitee is a director, officer, employee, agent or fiduciary of the Company or while a director, officer, employee, agent or fiduciary of the Company or is serving at the request of the Company as a director, officer, employee,
agent or fiduciary of any other entity (including, but not limited to, another corporation, partnership, joint venture, trust or employee benefit plan) and shall continue thereafter with respect to any possible claims based on the fact that
Indemnitee was a director, officer, employee, agent or fiduciary of the Company or was serving at the request of the Company as a director, officer, employee, agent or fiduciary of any other entity (including, but not limited to, another
corporation, partnership, joint venture, trust or employee benefit plan). This Agreement shall be binding upon all successors and assigns of the Company (including any transferee of all or substantially all of its assets and any successor by merger
or operation of law) and shall inure to the benefit of the heirs, personal representatives and estate of Indemnitee. 

  

	15.	 Notification and Defense of Claim. Promptly after receipt by Indemnitee of notice of any Proceeding,
Indemnitee will, if a claim in respect thereof is to be made against the Company under this Agreement, notify the Company in writing of the commencement thereof. Any failure by Indemnitee to notify the Company will relieve the Company of its
advancement or indemnification obligations under this Agreement only to the extent the Company can establish that such omission to notify resulted in actual prejudice to the Company, and the omission to notify the Company will, in any event, not
relieve the Company from any liability that the Company may have to indemnify Indemnitee or advance Expenses to Indemnitee otherwise than under this Agreement. Notwithstanding any other provision of this Agreement, with respect to any such
Proceeding of which Indemnitee notifies the Company: 

 (a) The Company shall be entitled to participate therein at its own
expense; and 
  

	1 	 Note: Bracketed sections should only be included in Indemnification Agreements where a director
is so designated. 

  
 9 

 (b) Except as otherwise provided in this Section 15(b), to the extent that it may wish,
the Company, jointly with any other indemnifying party similarly notified, shall be entitled to assume the defense thereof, with counsel reasonably satisfactory to Indemnitee. After notice from the Company to Indemnitee of its election so to assume
the defense thereof, the Company shall not be liable to Indemnitee under this Agreement for any fees or expenses of counsel subsequently incurred by Indemnitee in connection with the defense thereof except as otherwise provided below. Indemnitee
shall have the right to employ Indemnitee’s own counsel in such Proceeding, but the fees and expenses of such counsel incurred after notice from the Company of its assumption of the defense thereof shall be at the expense of Indemnitee unless
(i) the employment of counsel by Indemnitee has been authorized by the Company in writing, (ii) Indemnitee shall have reasonably concluded that there may be a conflict of interest between the Company and Indemnitee in the conduct of the
defense of such Proceeding or (iii) the Company shall not within sixty (60) days of receipt of notice from Indemnitee in fact have employed counsel to assume the defense of the Proceeding reasonably satisfactory to Indemnitee, in each of
which cases the reasonable fees and expenses of Indemnitee’s counsel shall be at the expense of the Company. The Company shall not be entitled to assume the defense of any Proceeding brought by or on behalf of the Company or as to which
Indemnitee shall have made the conclusion provided for in (ii) above; and 
 (c) If the Company has assumed the defense of a Proceeding,
the Company shall not be liable to indemnify Indemnitee under this Agreement for any amounts paid in settlement of any Proceeding effected without the Company’s written consent, or for any judicial or other award in connection with such
Proceeding, if the Company was not given an opportunity, in accordance with this Section 15, to participate in the defense of such Proceeding. The Company shall not settle any Proceeding in any manner that would impose any penalty or limitation
on or disclosure obligation with respect to Indemnitee, or that would directly or indirectly constitute or impose any admission or acknowledgment of fault or culpability with respect to Indemnitee, without Indemnitee’s written consent. Neither
the Company nor Indemnitee will unreasonably withhold consent to any proposed settlement. 
  

	16.	 Advancement of Expenses. All Expenses incurred by Indemnitee in defending any Proceeding described in
Section 3 or 4 shall be paid by the Company in advance of the final disposition of such Proceeding at the request of Indemnitee, each such payment to be made within thirty (30) days after the receipt by the General Counsel of the Company
(or if there is no General Counsel, or if Indemnitee is the General Counsel, the President of the Company) of a statement or statements from Indemnitee requesting such advance or advancements from time to time. Such statement or statements
(i) shall reasonably evidence the Expenses incurred by Indemnitee in connection therewith, (ii) shall include or be accompanied by such documentation and information as is reasonably requested by the Company to determine the nature of the
Proceeding and (iii) if requested by the Company because the undertaking in the next sentence is not deemed sufficient for any reason, shall include or be accompanied by a written undertaking, by or on behalf of Indemnitee, to reimburse such
amounts advanced if it is ultimately determined, by final judicial decision of a court of competent jurisdiction from which there is no further right to appeal, that Indemnitee is not entitled to be indemnified against such Expenses by the Company
as provided by this Agreement or otherwise. In this regard, Indemnitee hereby expressly undertakes to repay any Expenses advanced to Indemnitee if it shall ultimately be determined by final judicial decision of a court of competent jurisdiction from
which there is no further right to appeal that Indemnitee is not entitled to be indemnified against such Expenses. Any advances or undertakings to repay pursuant to this Section 16 shall be unsecured. In addition, subject to compliance with the
foregoing, Indemnitee shall be entitled to advancement of Expenses incurred in connection with any action, suit or proceeding by Indemnitee seeking a judgment in court or an 

  
 10 

	 	
adjudication or award in arbitration pursuant to this Agreement (including the enforcement of this provision). Indemnitee’s right to advancement of Expenses shall not be subject to any
standard of conduct and advances shall be made without regard to Indemnitee’s ultimate entitlement to indemnification under the provisions of this Agreement or otherwise. 

 

	17.	 Separability; Prior Indemnification Agreements. If any provision or provisions of this Agreement shall
be held to be invalid, illegal or unenforceable for any reason whatsoever (a) the validity, legality and enforceability of the remaining provisions of this Agreement (including without limitation, all portions of any paragraphs of this
Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not by themselves invalid, illegal or unenforceable) shall not in any way be affected or impaired thereby, and (b) to the fullest extent possible,
the provisions of this Agreement (including, without limitation, all portions of any paragraph of this Agreement containing any such provision held to be invalid, illegal or unenforceable, that are not themselves invalid, illegal or unenforceable)
shall be construed so as to give effect to the intent of the parties that the Company provide protection to Indemnitee to the fullest enforceable extent. This Agreement shall supersede and replace any prior indemnification agreements entered into by
and between the Company or its affiliates or subsidiaries, including, but not limited to, Quidel Corporation, Ortho Clinical Diagnostics Holdings plc and U.S. Crimson Acquisition Inc., and Indemnitee and any such prior agreements shall be terminated
automatically upon execution of this Agreement, without any further action by the parties. 

  

	18.	 Headings; References; Pronouns. The headings of the sections of this Agreement are inserted for
convenience only and shall not be deemed to constitute part of this Agreement or to affect the construction thereof. References herein to section numbers are to sections of this Agreement. All pronouns and any variations thereof shall be deemed to
refer to the masculine, feminine, neuter, singular or plural as appropriate. 

  

	19.	 Definitions. For purposes of this Agreement: 

(a) A “Change in Control” will be deemed to have occurred: 

 

	 	(i)	 if with respect to any particular 24-month period, the individuals who,
at the beginning of such 24-month period, constituted the Board of Directors (the “Incumbent Board”) cease for any reason to constitute at least a majority of the Board of Directors; provided,
however, that any individual becoming a director subsequent to the beginning of such 24-month period whose election, or nomination for election by the stockholders of the Company, was approved by a vote
of at least a majority of the directors then comprising the Incumbent Board shall be considered as though such individual were a member of the Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office
occurs as a result of an actual or threatened election contest with respect to the election or removal of directors or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board of Directors;

  

	 	(ii)	 if any person, entity or group becomes the beneficial owner (within the meaning of Rule 13d-3 promulgated under the Securities Exchange Act) of more than 50% of either the then outstanding shares of Common Stock or the combined voting power of the Company’s then outstanding securities entitled to
vote generally in the election of directors; or 

  
 11 

	 	(iii)	 upon the consummation by the Company of the sale or other disposition by the Company of all or substantially
all of the Company’s assets or a merger, consolidation or other reorganization of the Company (a “Reorganization”) with any other person, corporation or other entity, other than: 

 

	 	1)	 a Reorganization that would result in the voting securities of the Company outstanding immediately prior
thereto (or, in the case of a Reorganization that is preceded or accomplished by an acquisition or series of related acquisitions by any person, entity or group, by tender or exchange offer or otherwise, of voting securities representing 5% or more
of the combined voting power of all securities of the Company, immediately prior to such acquisition or the first acquisition in such series of acquisitions) continuing to represent, either by remaining outstanding or by being converted into voting
securities of another entity, more than 50% of the combined voting power of the voting securities of the Company or such other entity outstanding immediately after such Reorganization (or series of related transactions involving such a
Reorganization), or 

  

	 	2)	 a Reorganization effected to implement a recapitalization or reincorporation of the Company (or similar
transaction) that does not result in a material change in beneficial ownership of the voting securities of the Company or its successor. 

A “Change in Control” will not be deemed to have occurred for purposes of this Agreement until the transaction (or series of
transactions) that would otherwise be considered a “Change in Control” closes. 
 (b) “Corporate Status”
describes the status of a person who is or was acting as a director, officer, employee, fiduciary, or agent of the Company or an Enterprise. 

[(c) “Designating Stockholder” means any person that is a direct or indirect equityholder of the Company and to whom
the Company has granted the right to designate, appoint or nominate a person to the Board of Directors and/or the affiliates of such person; provided, that the provisions of this Agreement referencing the Designating Stockholder shall only be
interpreted and applicable with respect to and to the extent that Indemnitee is designated as a director of the Company pursuant to such right.]2 

(d) “Disinterested Director” means a director of the Company who is not or was not a party to the Proceeding in respect
of which indemnification is being sought by Indemnitee. 
 (e) “Enterprise” means any other corporation, limited
liability company, partnership, joint venture, trust, employee benefit plan or other entity, for which Indemnitee is or was serving at the request of the Company as a director, officer, employee, or agent. 

(f) “Expenses” shall include, without limitation, all reasonable attorneys’ fees, witness fees and expenses, fees
and expenses of advisors and experts, retainers, court costs, transcript costs, travel expenses, duplicating, printing and binding costs, postage, delivery service fees and all other disbursements or expenses of the types customarily and reasonably
incurred in connection with prosecuting, defending, preparing to prosecute or defend, investigating, being or preparing to be a 
  

	2 	 Note: Bracketed section should only be included in Indemnity Agreements where a director is so
designated. 

  
 12 

 
witness in, or otherwise participating in, a proceeding and any expenses of establishing a right to indemnification or advancement under Sections 9, 11, 13 and 16 hereof, but shall not include
the amount of judgments, fines or penalties actually levied against Indemnitee, or any amounts paid in settlement by or on behalf of Indemnitee. 

(g) “Independent Counsel” means a nationally recognized law firm or a member of a nationally recognized law firm that
(i) has significant experience in matters involving the DGCL generally; (ii) has significant experience in matters involving the indemnification of officers and directors of public companies; and (iii) neither is currently nor in the
past five years has been retained to represent (1) the Company or Indemnitee in any matter material to either such party (other than with respect to matters concerning Indemnitee under this Agreement, or of other indemnitees under similar
indemnification agreements to which the Company is a party), or (2) any other party to the Proceeding giving rise to a claim for indemnification hereunder. Notwithstanding the foregoing, the term “Independent Counsel” shall not
include any person who, under the applicable standards of professional conduct then prevailing, would have a conflict of interest in representing either the Company or Indemnitee in an action to determine Indemnitee’s right to indemnification
under this Agreement. The Company agrees to pay the reasonable fees and expenses of the Independent Counsel. 
 (h)
“Proceeding” includes any actual, threatened, pending or completed investigation, action, suit, arbitration, alternate dispute resolution mechanism, inquiry, judicial, legislative or administrative hearing or any other
actual, threatened, pending or completed proceeding, whether brought by or in the right of the Company or otherwise, against Indemnitee, for which indemnification is not prohibited under Sections 2(a)-(g) above and whether of a civil, criminal,
administrative, investigative or other nature, including, but not limited to, actions, suits or proceedings in which Indemnitee may be or may have been involved as a party or otherwise, by reason of the fact that Indemnitee is or was a director,
officer, employee, agent or fiduciary of the Company, or while a director, officer, employee, agent or fiduciary of the Company is or was serving, at the request of the Company, as a director, officer, employee or agent or fiduciary of any other
entity, including, but not limited to, another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise, or by reason of anything done or not done by Indemnitee in any such capacity, whether or not Indemnitee is
serving in such capacity at the time any liability or expense is incurred for which indemnification or reimbursement can be provided under this Agreement. 
  

	20.	 Other Provisions. 

(a) This Agreement shall be interpreted and enforced in accordance with the laws of the State of Delaware. 

(b) This Agreement may be executed in one or more counterparts, each of which shall for all purposes be deemed to be an original but all of
which together shall constitute one and the same Agreement. Only one such counterpart signed by the party against whom enforceability is sought needs to be produced as evidence of the existence of this Agreement. 

(c) This Agreement shall not be deemed an employment contract between the Company and any Indemnitee who is an officer or other employee of the
Company, and, if Indemnitee is an officer or other employee of the Company, Indemnitee specifically acknowledges that Indemnitee may be discharged at any time for any reason, with or without cause, and with or without severance compensation, except
as may be otherwise provided in a separate written contract between Indemnitee and the Company. 

  
 13 

 (d) Upon a payment to Indemnitee under this Agreement, the Company shall be subrogated to
the extent of such payment to all of the rights of Indemnitee to recover against any other person for such liability, and Indemnitee shall execute all documents and instruments required and shall take such other actions as may be necessary to secure
such rights, including the execution of such documents as may be necessary for the Company to bring suit to enforce such rights. 
 (e) No
supplement, modification or amendment of this Agreement shall be binding unless executed in writing by both parties hereto. No waiver of any of the provisions of this Agreement shall be deemed or shall constitute a waiver of any other provisions
hereof (whether or not similar) nor shall such waiver constitute a continuing waiver. 
 (f) All notices, requests, demands and other
communications hereunder shall be in writing and shall be deemed to have been duly given (i) if delivered by hand and receipted for by the party to whom said notice or other communication shall have been directed or (ii) mailed by
