 Re: Severance Agreement April 2020 

Dear Carolyn Short, 
 BioAtla, LLC (the “Company-), is pleased to provide the following Amended Severance Agreement (the -Agreement”) to you (the “Executive”). This
Agreement will be effective only if you sign and return this Agreement within ten (10) business days. 
 1. Eligibility /
Severance Benefits. If (i) your employment ceases at any time prior to a Change in Control (a “Qualifying Termination”), for any reason other than termination for Cause, and (ii) you satisfy the Release Requirement (as
defined in Section 2 below), then you will receive the following “Severance Benefits”: 
 1.1. Severance
Payment. A severance payment equal to twenty-four (24) months of the greater of: i) your final monthly base salary prior to any company wide salary reduction plan, or ii) in the event your date of termination occurs prior to a salary
increase for the previous year performance, your final monthly base salary prior to any company wide salary reduction plan including the greater of: a) the maximum salary increase percentage provided to any employee (without a title change) or b) 4%
(the “Severance Payment”). The Severance Payment will be paid to you, in the form of monthly payments beginning the later date of the following: 1) the date of termination and for twenty-four months thereafter, subject to required
payroll deductions and tax withholdings, and 2) the day of the Release Effective Date (as defined in Section 2 below). Further, for purposes of calculating the Severance Payment, your final base salary will be calculated prior to giving effect
to any reduction in base salary that would give rise to your right to resign for Good Reason. You will be eligible for the company bonus as set forth below. 

1.2. Bonus Payment. An amount equal to your target bonus amount for the full year of the Termination Year (the “Target
Bonus Amount”) will be paid to you, in the form of 12 monthly payments, subject to required payroll deductions and tax withholdings. For purposes of calculating the Target Bonus Amount for the Termination Year, the same final base salary
used in 1.1 above will be used. 
 1.3. Prior Year Bonus Payment. If the Qualifying Termination occurs prior to the date on
which bonuses are paid for the year immediately preceding the Termination Year (the “Prior Year”), an amount equal to your full target bonus amount for the Prior Year (the “Prior Year Bonus Payment”) will be paid to
you (if applicable), in the form of 12 monthly payments, subject to required payroll deductions and tax withholdings, within twenty (20) business days following the Release Effective Date. For purposes of calculating the Prior Year Bonus
Payment, the same final base salary used in 1.1 above will be used.

 1.4. Double Trigger Accelerated Vesting. The vesting and exercisability of all
unvested time-based vesting equity awards then held by you shall accelerate such that all shares become immediately vested and exercisable, if applicable, by you upon such termination and shall remain exercisable, if applicable, following your
termination as set forth in the applicable equity award documents. With respect to any performance-based vesting equity award, such award shall continue to be governed in all respects by the terms of the applicable equity award documents. 

2. Conditions to Receipt of Severance Benefits. To be eligible for any of the Severance Benefits pursuant to Section 1 of
this Agreement, you must satisfy the following release requirement (the “Release Requirement”): return to the Company a signed and dated general release of all known and unknown claims in a termination agreement acceptable to the
Company (the “Release”) within the applicable deadline set forth therein, but in no event later than forty-five (45) calendar days following your termination date, and permit the Release to become effective and irrevocable in
accordance with its terms (such effective date of the Release, the “Release Effective Date”). No Severance Benefits will be paid hereunder prior to the Release Effective Date. Accordingly, if you refuse to sign and deliver to the
Company an executed Release or you sign and deliver to the Company the Release but exercise your right, if any, under applicable law to revoke the Release (or any portion thereof), then you will not be entitled to any severance, payment or benefit
under this Agreement. 
 3. IRS Code Section 409A. All payments provided hereunder are intended to
constitute separate payments for purposes of Treasury Regulation Section 1.409A-2(b) (2). If the Company determines that any benefits provided under this Agreement constitute “deferred
compensation” under Section 409A of the Internal Revenue Code of 1986 as amended (“Section 409A”), such benefits will not commence in connection with your termination of employment unless such
termination also qualifies as a “separation from service” with the Company within the meaning of Treasury Regulation Section 1.409A-1(h) (without regard to any permissible alternative definition
thereunder) (“Separation from Service”). If the Company determines that any benefits provided under this Agreement constitute “deferred compensation” under Section 409A and you are a “specified employee” of
the Company or any affiliate thereof (or any successor entity thereto) within the meaning of Section 409A(aX2XB)(i) of the Code on the date of your Separation from Service, then the payment of any such benefits shall be delayed until the
earlier of: (i) the date that is six (6) months and one (1) day after the date of your Separation from Service, or (ii) the date of your death (such date, the “Delayed Payment Date”), and the Company (or the
successor entity thereto, as applicable) shall (A) pay to you a lump sum amount equal to the sum of the benefit payments that otherwise would have been paid to you on or before the Delayed Payment Date, without any adjustment on account of such
delay, and (B) continue the benefit payments in accordance with any applicable payment schedules set forth for the balance of the period specified herein. In addition to the above, to the extent required to comply with Section 409A and the
applicable regulations and guidance issued thereunder, if the applicable deadline for you to execute (and not revoke) the applicable Release spans two calendar years, the Release Effective Date shall not be deemed to occur until the second calendar
year.

 4. Section 280G; Limitations on Payment. 

4.1. If any payment or benefit you will or may receive from the Company or otherwise (a “280G Payment”) would
(i) constitute a “parachute payment” within the meaning of Section 280G of the Code, and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”),
then any such 280G Payment provided pursuant to this Agreement (a “Payment”) shall be equal to the Reduced Amount. The “Reduced Amount” shall be either (x) the largest portion of the Payment that would result in no
portion of the Payment (after reduction) being subject to the Excise Tax or (y) the largest portion, up to and including the total, of the Payment, whichever amount (i.e., the amount determined by clause (x) or by clause (y)), after taking
into account all applicable federal, state and local employment taxes, income taxes, and the Excise Tax (all computed at the highest applicable marginal rate), results in Executive’s receipt, on an
after-tax basis, of the greater economic benefit notwithstanding that all or some portion of the Payment may be subject to the Excise Tax. If a reduction in a Payment is required pursuant to the preceding
sentence and the Reduced Amount is determined pursuant to clause (x) of the preceding sentence, the reduction shall occur in the manner (the “Reduction Method”) that results in the greatest economic benefit for you. If more
than one method of reduction will result in the same economic benefit, the items so reduced will be reduced pro rata (the “Pro Rata Reduction Method”). 

4.2. Notwithstanding any provision of Section 4.1 to the contrary, if the Reduction Method or the Pro Rata Reduction Method would
result in any portion of the Payment being subject to taxes pursuant to Section 409A that would not otherwise be subject to taxes pursuant to Section 409A, then the Reduction Method and/or the Pro Rata Reduction Method, as the case may be,
shall be modified so as to avoid the imposition of taxes pursuant to Section 409A as follows: (A) as a first priority, the modification shall preserve to the greatest extent possible, the greatest economic benefit for Executive as
determined on an after-tax basis; (B) as a second priority, Payments that are contingent on future events (e.g., being terminated without Cause), shall be reduced (or eliminated) before Payments
that are not contingent on future events; and (C) as a third priority, Payments that are “deferred compensation” within the meaning of Section 409A shall be reduced (or eliminated) before Payments that are not deferred
compensation within the meaning of Section 409A. 
 4.3. Unless you and the Company agree on an alternative accounting firm or,
the accounting firm engaged by the Company for general tax compliance purposes as of the day prior to the effective date of the Change in Control transaction shall perform the foregoing calculations. If the accounting firm so engaged by the Company
is serving as accountant or auditor for the individual, entity or group effecting the Change in Control transaction, the Company shall appoint a nationally recognized accounting or law firm to make the determinations required by this Section 4.
The Company shall bear all expenses with respect to the determinations by such accounting firm required to be made hereunder. The Company shall use commercially reasonable efforts to cause the accounting or law firm engaged to make the
determinations hereunder to provide its calculations, together with detailed supporting documentation, to you and the Company within fifteen (15) calendar days after the date on which your right to a 280G Payment becomes reasonably likely to
occur (if requested at that time by you or the Company) or such other time as requested by you or the Company.

 4.4. If you receive a Payment for which the Reduced Amount was determined pursuant to
clause (x) of Section 4.1 and the Internal Revenue Service determines thereafter that some portion of the Payment is subject to the Excise Tax, you agree to promptly return to the Company a sufficient amount of the Payment (after reduction
pursuant to clause (x) of Section 4.1) so that no portion of the remaining Payment is subject to the Excise Tax. For the avoidance of doubt, if the Reduced Amount was determined pursuant to clause (y) of Section 4.1, you shall
have no obligation to return any portion of the Payment pursuant to the preceding sentence. 
 5. Definitions. 

5.1. Change in Control. For purposes of this Agreement, the term “Change in Control” means a transaction or
series of transactions (including by way of merger, consolidation, recapitalization, reorganization or sale of stock or units), the result of which is that Jay Short and Carolyn Short are, after giving effect to such transaction, no longer, in the
aggregate, in control, directly or indirectly (including through one or more intermediaries and/or voting rights agreements), of more than 50% of the voting power of the outstanding voting securities of the surviving entity of such transaction, and
including a capital raising transaction in which the Company is the surviving entity. 
 5.2. Termination Year. For purposes
of this Agreement, “Termination Year” means the fiscal year in which your Company employment is terminated for any reason. 

5.3. Good Reason. For purposes of this Agreement, “Good Reason” is a Qualifying Termination, and Good Reason
includes Company requiring Executive to work full time for Himalaya Therapeutics (“Himalaya”), to advance Himalaya’s development and commercialization of Company’s products under the rights agreement with Himalaya in the
Himalaya territory. 
 6. Miscellaneous. Nothing in this Agreement is intended to alter the
at-will nature of your employment with the Company or the terms of any offer letter and/or employment-related agreement with the Company. This Agreement constitutes the complete, final and exclusive embodiment
of the entire agreement between the Company and you with regard to Severance Benefits, and it supersedes and replaces any other agreements (whether written or unwritten) you may have with the Company concerning any severance benefits. This Agreement
is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and it supersedes any other such promises, warranties or representations. This Agreement may not be modified or amended
except in a written agreement approved by the Board and signed by you and a duly authorized and independent member of the Board. This Agreement will bind the heirs, personal representatives, successors and assigns of both you and the Company, and
inure to the benefit of both you and the Company, their heirs, successors and assigns. If any provision of this Agreement is determined to be invalid or unenforceable, in whole or in part, this determination shall not affect any other provision of
this Agreement and the provision in question shall be modified so as to be rendered enforceable in a

manner consistent with the intent of the parties insofar as possible under applicable law. This Agreement shall be construed and enforced in accordance with the laws of the State of California
without regard to conflicts of law principles. Any ambiguity in this Agreement shall not be construed against either party as the drafter. Any waiver of a breach of this Agreement, or rights hereunder, shall be in writing and shall not be deemed to
be a waiver of any successive breach or rights hereunder. This Agreement may be executed in counterparts which shall be deemed to be part of one original, and facsimile signatures, and signatures sent via PDF, shall be equivalent to original
signatures. 
 To indicate your understanding and acceptance of this Agreement, please sign and date below, and return this Agreement to the Company.

Re: Severance Agreement 
 Dear Carolyn Short, 

BioAtla, LLC (the “Company”), is pleased to provide the following Severance Agreement (the “Agreement”) to you. This
Agreement will be effective only if you sign and return this Agreement within ten (10) business days. 
 1. Eligibility /
Severance Benefits. If (i) your employment ceases at any time following a Change in Control (either, a “Qualifying Termination”), and (ii) you satisfy the Release Requirement (as defined in Section 2 below), then
you will receive the following “Severance Benefits”: 
 1.1. Severance Payment. A severance payment equal to
eighteen (18) months of your final monthly base salary (the “Severance Payment”). The Severance Payment will be paid to you, in the form of a lump sum payment, subject to required payroll deductions and tax withholdings, within
twenty (20) business days following the Release Effective Date (as defined in Section 2 below). For purposes of calculating the Severance Payment, your final base salary will be calculated prior to giving effect to any reduction in base
salary that would give rise to your right to resign for Good Reason. 
 1.2. Prorata Bonus Payment. An amount equal to a
prorated portion of your target bonus amount for the Termination Year (the “Target Bonus Amount”) that corresponds to your service during the Termination Year (the “Prorata Bonus Payment”), which shall be calculated
by multiplying (i) the Target Bonus Amount, by (ii) a fraction, the numerator of which is the number of days during the Termination Year that you were employed by the Company and the denominator of which is three hundred and sixty-five
(365). The Prorata Bonus Payment will be paid to you, in the form of a lump sum payment, subject to required payroll deductions and tax withholdings, within twenty (20) business days following the Release Effective Date. For purposes of
calculating the Target Bonus Amount for any Termination Year, your final base salary will be calculated prior to giving effect to any reduction in base salary that would give rise to your right to resign for Good Reason. 

1.3. Prior Year Bonus Payment. If the Qualifying Termination occurs prior to the date on which bonuses are paid for the year
immediately preceding the Termination Year (the “Prior Year”), an amount equal to your full target bonus amount for the Prior Year (the “Prior Year Bonus Payment”). The Prior Year Bonus Payment will be paid to you
(if applicable), in the form of a lump sum payment, subject to required payroll deductions and tax withholdings, within twenty (20) business days following the Release Effective Date. For purposes of calculating the Prior Year Bonus Payment,
your final base salary will be calculated prior to giving effect to any reduction in base salary that would give rise to your right to resign for Good Reason. 

 1.4. Double Trigger Accelerated Vesting. The vesting and exercisability of all
unvested time-based vesting equity awards then held by you shall accelerate such that all shares become immediately vested and exercisable, if applicable, by you upon such termination and shall remain exercisable, if applicable, following your

Company an executed Release or you sign and deliver to the Company the Release but exercise your right, if any, under applicable law to revoke the Release (or any portion thereof), then you will not be entitled to any severance, payment or benefit
under this Agreement. 
 3. IRS Code Section 409A. All payments provided hereunder are intended to

 Exhibit 10.18 

INDEMNIFICATION AGREEMENT 

THIS INDEMNIFICATION AGREEMENT (the “Agreement”) is made and entered into as of [•], 2020, between BioAtla, Inc., a
Delaware corporation (the “Company”), and [name] (“Indemnitee”). 
 WITNESSETH THAT: 

WHEREAS, highly competent persons have become more reluctant to serve corporations as directors, officers or in other capacities unless
they are provided with adequate protection through insurance or adequate indemnification against inordinate risks of claims and actions against them arising out of their service to and activities on behalf of the corporation; 

WHEREAS, the Board of Directors of the Company (the “Board”) has determined that, in order to attract and retain
qualified individuals, the Company will attempt to maintain on an ongoing basis, at its sole expense, liability insurance to protect persons serving the Company and its subsidiaries from certain liabilities. Although the furnishing of such insurance
has been a customary and widespread practice among United States-based corporations and other business enterprises, the Company believes that, given current market conditions and trends, such insurance may be available to it in the future only at
higher premiums and with more exclusions. At the same time, directors, officers, and other persons in service to corporations or business enterprises are being increasingly subjected to expensive and time-consuming litigation relating to, among
other things, matters that traditionally would have been brought only against the Company or business enterprise itself. The Bylaws and Certificate of Incorporation of the Company require indemnification of the officers and directors of the Company.
Indemnitee may also be entitled to indemnification pursuant to the General Corporation Law of the State of Delaware (“DGCL”). The Bylaws, Certificate of Incorporation and the DGCL expressly provide that the indemnification
provisions set forth therein are not exclusive, and thereby contemplate that contracts may be entered into between the Company and members of the Board, officers and other persons with respect to indemnification; 

WHEREAS, the uncertainties relating to such insurance and to indemnification have increased the difficulty of attracting and retaining
such persons; 
 WHEREAS, the Board has determined that the increased difficulty in attracting and retaining such persons is
detrimental to the best interests of the Company’s stockholders and that the Company should act to assure such persons that there will be increased certainty of such protection in the future; 

WHEREAS, it is reasonable, prudent and necessary for the Company contractually to obligate itself to indemnify, and to advance expenses
on behalf of, such persons to the fullest extent permitted by applicable law so that they will serve or continue to serve the Company free from undue concern that they will not be so indemnified; 

WHEREAS, this Agreement is a supplement to and in furtherance of the Bylaws and Certificate of Incorporation of the Company and any
resolutions adopted pursuant thereto, and shall not be deemed a substitute therefor, nor to diminish or abrogate any rights of Indemnitee thereunder; 

 WHEREAS, Indemnitee does not regard the protection available under the Company’s
Bylaws, Certificate of Incorporation and insurance as adequate in the present circumstances, and may not be willing to serve as an officer or director without adequate protection, and the Company desires Indemnitee to serve in such capacity.
Indemnitee is willing to serve, continue to serve and to take on additional service for or on behalf of the Company on the condition that he be so indemnified; and 

WHEREAS, Indemnitee has certain rights to indemnification and/or insurance provided by [name of fund/sponsor] which Indemnitee
and [name of fund/sponsor] intend to be secondary to the primary obligation of the Company to indemnify Indemnitee as provided herein, with the Company’s acknowledgement and agreement to the foregoing being a material condition to
Indemnitee’s willingness to serve on the Board. 
 NOW, THEREFORE, in consideration of Indemnitee’s agreement to serve as
[a director][an officer] from and after the date hereof, the parties hereto agree as follows: 
 1. Indemnity of Indemnitee. The
Company hereby agrees to hold harmless and indemnify Indemnitee to the fullest extent permitted by law, as such may be amended from time to time. In furtherance of the foregoing indemnification, and without limiting the generality thereof. 

(a) Proceedings Other Than Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification
provided in this Section l(a) if, by reason of his Corporate Status (as hereinafter defined), the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding (as hereinafter defined) other than a Proceeding by or
in the right of the Company. Pursuant to this Section 1(a), Indemnitee shall be indemnified against all Expenses (as hereinafter defined), judgments, penalties, fines and amounts paid in settlement actually and reasonably
incurred by him, or on his behalf, in connection with such Proceeding or any claim, issue or matter therein, if the Indemnitee acted in good faith and in a manner the Indemnitee 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 the Indemnitee’s conduct was unlawful. 

(b) Proceedings by or in the Right of the Company. Indemnitee shall be entitled to the rights of indemnification provided in this
Section 1(b) if, by reason of his Corporate Status, the Indemnitee is, or is threatened to be made, a party to or participant in any Proceeding brought by or in the right of the Company. Pursuant to this
Section 1(b), Indemnitee shall be indemnified against all Expenses actually and reasonably incurred by the Indemnitee, or on the Indemnitee’s behalf, in connection with such Proceeding if the Indemnitee acted in good
faith and in a manner the Indemnitee reasonably believed to be in or not opposed to the best interests of the Company; provided, however, if applicable law so provides, no indemnification against such Expenses shall be made in respect
of any claim, issue or matter in such Proceeding as to which Indemnitee shall have been adjudged to be liable to the Company unless and to the extent that the Court of Chancery of the State of Delaware shall determine that such indemnification may
be made. 

  
 2 

 (c) Indemnification for Expenses of a Party Who is Wholly or Partly Successful.
Notwithstanding any other provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a party to and is successful, on the merits or otherwise, in any Proceeding, he shall be indemnified to the maximum extent
permitted by law, as such may be amended from time to time, against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If Indemnitee is not wholly successful in such Proceeding but is successful, on the
merits or otherwise, as to one or more but less than all claims, issues or matters in such Proceeding, the Company shall indemnify Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf in connection with each
successfully resolved claim, issue or matter. For purposes of this Section and without limitation, the termination of any claim, issue or matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result
as to such claim, issue or matter.  
 (d) Indemnification of Appointing Stockholder. If (i) Indemnitee is or was
affiliated with one or more venture capital or private equity funds that has invested in the Company (an “Appointing Stockholder”), (ii) the Appointing Stockholder is, or is threatened to be made, a party to or a participant in any
Proceeding, and (iii) the Appointing Stockholder’s involvement in the Proceeding results from any claim based on the Indemnitee’s service to the Company as a director or other fiduciary of the Company, the Appointing Stockholder will
be entitled to indemnification hereunder for Expenses to the same extent as Indemnitee, and the terms of this Agreement as they relate to procedures for indemnification of Indemnitee and advancement of Expenses shall apply to any such
indemnification of Appointing Stockholder. 
 2. Additional Indemnity. In addition to, and without regard to any limitations on, the
indemnification provided for in Section 1 of this Agreement, the Company shall and hereby does indemnify and hold harmless Indemnitee against all Expenses, judgments, penalties, fines and amounts paid in settlement actually
and reasonably incurred by him or on his behalf if, by reason of his Corporate Status, he is, or is threatened to be made, a party to or participant in any Proceeding (including a Proceeding by or in the right of the Company), including, without
limitation, all liability arising out of the negligence or active or passive wrongdoing of Indemnitee. The only limitation that shall exist upon the Company’s obligations pursuant to this Agreement shall be that the Company shall not be
obligated to make any payment to Indemnitee that is finally determined (under the procedures, and subject to the presumptions, set forth in Sections 6 and 7 hereof) to be unlawful. 

3. Contribution. 
 (a)
Whether or not the indemnification provided in Sections 1 and 2 hereof is available, in respect of any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if
joined in such action, suit or proceeding), the Company shall pay, in the first instance, the entire amount of any judgment or settlement of such action, suit or proceeding without requiring Indemnitee to contribute to such payment and the Company
hereby waives and relinquishes any right of contribution it may have against Indemnitee. The Company shall not enter into any settlement of any action, suit or proceeding in which the Company is jointly liable with Indemnitee (or would be if joined
in such action, suit or proceeding) unless such settlement provides for a full and final release of all claims asserted against Indemnitee. 

  
 3 

 (b) Without diminishing or impairing the obligations of the Company set forth in the
preceding subparagraph, if, for any reason, Indemnitee shall elect or be required to pay all or any portion of any judgment or settlement in any threatened, pending or completed action, suit or proceeding in which the Company is jointly liable with
Indemnitee (or would be if joined in such action, suit or proceeding), the Company shall contribute to the amount of Expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred and paid or payable by Indemnitee in
proportion to the relative benefits received by the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on the one
hand, and Indemnitee, on the other hand, from the transaction or events from which such action, suit or proceeding arose; provided, however, that the proportion determined on the basis of relative benefit may, to the extent necessary
to conform to law, be further adjusted by reference to the relative fault of the Company and all officers, directors or employees of the Company other than Indemnitee who are jointly liable with Indemnitee (or would be if joined in such action, suit
or proceeding), on the one hand, and Indemnitee, on the other hand, in connection with the transaction or events that resulted in such expenses, judgments, fines or settlement amounts, as well as any other equitable considerations which applicable
law may require to be considered. The relative fault of the Company and all officers, directors or employees of the Company, other than Indemnitee, who are jointly liable with Indemnitee (or would be if joined in such action, suit or proceeding), on
the one hand, and Indemnitee, on the other hand, shall be determined by reference to, among other things, the degree to which their actions were motivated by intent to gain personal profit or advantage, the degree to which their liability is primary
or secondary and the degree to which their conduct is active or passive. 
 (c) The Company hereby agrees to fully indemnify and hold
Indemnitee harmless from any claims of contribution which may be brought by officers, directors, or employees of the Company, other than Indemnitee, who may be jointly liable with Indemnitee. 

(d) To the fullest extent permissible under applicable law, if the indemnification provided for in this Agreement is unavailable to Indemnitee
for any reason whatsoever, the Company, in lieu of indemnifying Indemnitee, shall contribute to the amount incurred by Indemnitee, whether for judgments, fines, penalties, excise taxes, amounts paid or to be paid in settlement and/or for Expenses,
in connection with any claim relating to an indemnifiable event under this Agreement, in such proportion as is deemed fair and reasonable in light of all of the circumstances of such Proceeding in order to reflect (i) the relative benefits
received by the Company and Indemnitee as a result of the event(s) and/or transaction(s) giving cause to such Proceeding and/or (ii) the relative fault of the Company (and its directors, officers, employees and agents) and Indemnitee in
connection with such event(s) and/or transaction(s). 
 4. Indemnification for Expenses of a Witness. Notwithstanding any other
provision of this Agreement, to the extent that Indemnitee is, by reason of his Corporate Status, a witness, or is made (or asked) to respond to discovery requests, in any Proceeding to which Indemnitee is not a party, he shall be indemnified
against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. 
 5. Advancement of Expenses.
Notwithstanding any other provision of this Agreement, the Company shall advance all Expenses incurred by or on behalf of Indemnitee in connection with any Proceeding by reason of Indemnitee’s Corporate Status within thirty (30) days after
the receipt by the Company of a statement or statements from Indemnitee requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the
Expenses incurred by 

  
 4 

 
Indemnitee and shall include or be preceded or accompanied by a written undertaking by or on behalf of Indemnitee to repay any Expenses advanced if it shall ultimately be determined that
Indemnitee is not entitled to be indemnified against such Expenses. Any advances and undertakings to repay pursuant to this Section 5 shall be unsecured and interest free. 

6. Procedures and Presumptions for Determination of Entitlement to Indemnification. It is the intent of this Agreement to secure for
Indemnitee rights of indemnity that are as favorable as may be permitted under the DGCL and public policy of the State of Delaware. Accordingly, the parties agree that the following procedures and presumptions shall apply in the event of any
question as to whether Indemnitee is entitled to indemnification under this Agreement: 
 (a) To obtain indemnification under this Agreement,
Indemnitee shall submit to the Company a written request, including therein or therewith such documentation and information as is reasonably available to Indemnitee and is reasonably necessary to determine whether and to what extent Indemnitee is
entitled to indemnification. The Secretary of the Company shall, promptly upon receipt of such a request for indemnification, advise the Board in writing that Indemnitee has requested indemnification. Notwithstanding the foregoing, any failure of
Indemnitee to provide such a request to the Company, or to provide such a request in a timely fashion, shall not relieve the Company of any liability that it may have to Indemnitee unless, and to the extent that, such failure actually and materially
prejudices the interests of the Company. 
 (b) Upon written request by Indemnitee for indemnification pursuant to the first sentence of
Section 6(a) hereof, a determination with respect to Indemnitee’s entitlement thereto shall be made in the specific case by one of the following four methods, which shall be at the election of the Board, unless a
Change in Control has occurred: (1) by a majority vote of the disinterested directors, even though less than a quorum, (2) by a committee of disinterested directors designated by a majority vote of the disinterested directors, even though
less than a quorum, (3) if there are no disinterested directors or if the disinterested directors so direct, by Independent Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee, or (4) if so
directed by the Board, by the stockholders of the Company. If a Change in Control has occurred, by Independent legal Counsel in a written opinion to the Board, a copy of which shall be delivered to the Indemnitee. For purposes hereof, disinterested
directors are those members of the Board who are not parties to the action, suit or proceeding in respect of which indemnification is sought by Indemnitee. 

(c) If the determination of entitlement to indemnification is to be made by Independent Counsel pursuant to
Section 6(b) hereof, the Independent Counsel shall be selected as provided in this Section 6(c). The Independent Counsel shall be selected by the Board. Indemnitee may, within ten (10) days
after such written notice of selection shall have been given, deliver to the Company a written objection to such selection; provided, however, that 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 13 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 6(a) hereof, no Independent Counsel
shall have been 

  
 5 

 
selected and not objected to, either the Company or Indemnitee may petition the Court of Chancery of the State of Delaware or other court of competent jurisdiction for resolution of any objection
which shall have been made by the Indemnitee to the Company’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 6(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 6(b) hereof, and the Company shall pay all reasonable fees and expenses incident to the procedures of this
Section 6(c), regardless of the manner in which such Independent Counsel was selected or appointed. 
 (d) In
making a determination with respect to entitlement to indemnification hereunder, the person or persons or entity making such determination shall presume that Indemnitee is entitled to indemnification under this Agreement. Anyone seeking to overcome
this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. Neither the failure of the Company (including by its directors or independent legal counsel) to have made a determination prior to the
commencement of any action pursuant to this Agreement that indemnification is proper in the circumstances because Indemnitee has met the applicable standard of conduct, nor an actual determination by the Company (including by its directors or
independent legal counsel) that Indemnitee has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that Indemnitee has not met the applicable standard of conduct. 

(e) Indemnitee shall be deemed to have acted in good faith if Indemnitee’s action is based on the records or books of account of the
Enterprise (as hereinafter defined), including financial statements, or on information supplied to Indemnitee by the officers of the Enterprise in the course of their duties, or on the advice of legal counsel for the Enterprise or on information or
records given or reports made to the Enterprise by an independent certified public accountant or by an appraiser or other expert selected with reasonable care by the Enterprise. In addition, the knowledge and/or actions, or failure to act, of any
director, officer, agent or employee of the Enterprise shall not be imputed to Indemnitee for purposes of determining the right to indemnification under this Agreement. Whether or not the foregoing provisions of this
Section 6(e) are satisfied, it shall in any event be presumed that Indemnitee has at all times acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Company. Anyone
seeking to overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (f) If
the person, persons or entity empowered or selected under Section 6 to determine whether Indemnitee is entitled to indemnification shall not have made a determination within sixty (60) days after receipt by the Company
of the request therefor, the 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 sixty (60) day period may be extended for a reasonable time, not to exceed an additional thirty (30) days, if the person, persons or entity making such determination with respect to entitlement to indemnification
in good faith requires such additional time to obtain or evaluate documentation and/or information relating 

  
 6 

 
thereto; and provided further, that the foregoing provisions of this Section 6(f) shall not apply if the determination of entitlement to indemnification is
to be made by the stockholders pursuant to Section 6(b) of this Agreement and if (A) within fifteen (15) days after receipt by the Company of the request for such determination, the Board 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
(B) a special meeting of stockholders is called within fifteen (15) 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. 
 (g) Indemnitee shall cooperate with the person, persons or entity making such determination with
respect to Indemnitee’s entitlement to indemnification, including providing to such person, persons or entity upon reasonable advance request any documentation or information which is not privileged or otherwise protected from disclosure and
which is reasonably available to Indemnitee and reasonably necessary to such determination. Any Independent Counsel, member of the Board or stockholder of the Company shall act reasonably and in good faith in making a determination regarding the
Indemnitee’s entitlement to indemnification under this Agreement. Any costs or expenses (including attorneys’ fees and disbursements) incurred by Indemnitee in so cooperating with the person, persons or entity making such determination
shall be borne by the Company (irrespective of the determination as to Indemnitee’s entitlement to indemnification) and the Company hereby indemnifies and agrees to hold Indemnitee harmless therefrom. 

(h) The Company acknowledges that a settlement or other disposition short of final judgment may be successful if it permits a party to avoid
expense, delay, distraction, disruption and uncertainty. In the event that any action, claim or proceeding to which Indemnitee is a party is resolved in any manner other than by adverse judgment against Indemnitee (including, without limitation,
settlement of such action, claim or proceeding with or without payment of money or other consideration) it shall be presumed that Indemnitee has been successful on the merits or otherwise in such action, suit or proceeding. Anyone seeking to
overcome this presumption shall have the burden of proof and the burden of persuasion by clear and convincing evidence. 
 (i) The
termination of any Proceeding or of any claim, issue or matter therein, by judgment, order, settlement or conviction, or upon a plea of nolo contendere or its equivalent, shall not (except as otherwise expressly provided in this Agreement) of itself
adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he 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 his conduct was unlawful. 
 7. Remedies of
Indemnitee. 
 (a) In the event that (i) a determination is made pursuant to Section 6 of this Agreement
that Indemnitee is not entitled to indemnification under this Agreement, (ii) advancement of Expenses is not timely made pursuant to Section 5 of this Agreement, (iii) no determination of entitlement to
indemnification is made pursuant to Section 6(b) of this Agreement within ninety (90) days after receipt by the Company of the request for indemnification, (iv) payment of indemnification is not made pursuant to
this Agreement within ten (10) days after 

  
 7 

 
receipt by the Company of a written request therefor, or (v) payment of indemnification is not made within ten (10) days after a determination has been made that Indemnitee is entitled
to indemnification or such determination is deemed to have been made pursuant to Section 6 of this Agreement, Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other
court of competent jurisdiction, of Indemnitee’s entitlement to such indemnification. Indemnitee shall commence such proceeding seeking an adjudication within one hundred eighty (180) days following the date on which Indemnitee first has
the right to commence such proceeding pursuant to this Section 7(a). The Company shall not oppose Indemnitee’s right to seek any such adjudication. 

(b) In the event that a determination shall have been made pursuant to Section 6(b) of this Agreement that
Indemnitee is not entitled to indemnification, any judicial proceeding commenced pursuant to this Section 7 shall be conducted in all respects as a de novo trial on the merits, and Indemnitee shall not be prejudiced by
reason of the adverse determination under Section 6(b). 
 (c) If a determination shall have been made pursuant to
Section 6(b) of this Agreement that Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 7,
absent (i) a misstatement by Indemnitee of a material fact, or an omission of a material fact necessary to make Indemnitee’s misstatement not materially misleading in connection with the application for indemnification, or (ii) a
prohibition of such indemnification under applicable law. 
 (d) In the event that Indemnitee, pursuant to this
Section 7, seeks a judicial adjudication of his rights under, or to recover damages for breach of, this Agreement, or to recover under any directors’ and officers’ liability insurance policies maintained by the
Company, the Company shall pay on his behalf, in advance, any and all expenses (of the types described in the definition of Expenses in Section 13 of this Agreement) actually and reasonably incurred by him in such judicial
adjudication, regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of expenses or insurance recovery. 

(e) The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 7
that the procedures and presumptions of this Agreement are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all the provisions of this Agreement. The Company shall indemnify Indemnitee against any
and all Expenses and, if requested by Indemnitee, shall (within ten (10) days after receipt by the Company of a written request therefore) advance, to the extent not prohibited by law, such expenses to Indemnitee, which are incurred by
Indemnitee in connection with any action brought by Indemnitee for indemnification or advance of Expenses from the Company under this Agreement or under any directors’ and officers’ liability insurance policies maintained by the Company,
regardless of whether Indemnitee ultimately is determined to be entitled to such indemnification, advancement of Expenses or insurance recovery, as the case may be. 

(f) Notwithstanding anything in this Agreement to the contrary, no determination as to entitlement to indemnification under this Agreement
shall be required to be made prior to the final disposition of the Proceeding. 

  
 8 

 8. Non-Exclusivity; Survival of Rights;
Insurance; Primacy of Indemnification; Subrogation. 
 (a) The rights of indemnification as provided by this Agreement shall not be
deemed exclusive of any other rights to which Indemnitee may at any time be entitled under applicable law, the Certificate of Incorporation, the By-laws, any agreement, a vote of stockholders, a resolution of
directors of the Company, or otherwise. No amendment, alteration or repeal of this Agreement or of any provision hereof shall limit or restrict any right of Indemnitee under this Agreement in respect of any action taken or omitted by such Indemnitee
in his Corporate Status prior to such amendment, alteration or repeal. To the extent that a change in the DGCL, whether by statute or judicial decision, permits greater indemnification than would be afforded currently under the Certificate of
Incorporation, By-laws and this Agreement, it is the intent of the parties hereto that Indemnitee shall enjoy by this Agreement the greater benefits so afforded by such change. No right or remedy herein
conferred is intended to be exclusive of any other right or remedy, and every other right and remedy shall be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise.
The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other right or remedy. 

(b) To the extent that the Company maintains an insurance policy or policies providing liability insurance for directors, officers, employees,
or agents or fiduciaries of the Company or of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise that such person serves at the request of the Company, Indemnitee shall be covered by such policy or
policies in accordance with its or their terms to the maximum extent of the coverage available for any director, officer, employee, agent or fiduciary under such policy or policies. If, at the time of the receipt of a notice of a claim pursuant to
the terms hereof, the Company has directors’ and officers’ liability insurance in effect, the Company shall give prompt notice of the commencement of such proceeding to the insurers in accordance with the procedures set forth in the
respective policies. The Company shall thereafter take all necessary or desirable action to cause such insurers to pay, on behalf of the Indemnitee, all amounts payable as a result of such proceeding in accordance with the terms of such policies.

 (c) The Company hereby acknowledges that Indemnitee has certain rights to indemnification, advancement of expenses and/or insurance
provided by [Name of Fund/Sponsor] and certain of its affiliates (collectively, the “Fund Indemnitors”). The Company hereby agrees (i) that it is the indemnitor of first resort (i.e., its obligations to Indemnitee are
primary and any obligation of the Fund Indemnitors to advance expenses or to provide indemnification for the same expenses or liabilities incurred by Indemnitee are secondary), (ii) that it shall be required to advance the full amount of expenses
incurred by Indemnitee and shall be liable for the full amount of all Expenses, judgments, penalties, fines and amounts paid in settlement to the extent legally permitted and as required by the terms of this Agreement and the Certificate of
Incorporation or Bylaws of the Company (or any other agreement between the Company and Indemnitee), without regard to any rights Indemnitee may have against the Fund Indemnitors, and (iii) that it irrevocably waives, relinquishes and releases
the Fund Indemnitors from any and all claims against the Fund Indemnitors for contribution, subrogation or any other recovery of any kind in respect thereof. The Company further agrees that no advancement or payment by the Fund Indemnitors on behalf
of Indemnitee with respect to any claim for which Indemnitee has sought indemnification from the Company shall affect the foregoing and the Fund Indemnitors shall have a right of contribution and/or be subrogated to the extent of such advancement or
payment to all of the rights of recovery of Indemnitee against the Company. The Company and Indemnitee agree that the Fund Indemnitors are express third party beneficiaries of the terms of this Section 8(c). 

  
 9 

 (d) Except as provided in paragraph (c) above, in the event of any payment under this
Agreement, the Company shall be subrogated to the extent of such payment to all of the rights of recovery of Indemnitee (other than against the Fund Indemnitors), who shall execute all papers required and take all action necessary to secure such
rights, including execution of such documents as are necessary to enable the Company to bring suit to enforce such rights. 
 (e) Except as
provided in paragraph (c) above, the Company shall not be liable under this Agreement to make any payment of amounts otherwise indemnifiable hereunder if and to the extent that Indemnitee has otherwise actually received such payment under any
insurance policy, contract, agreement or otherwise. 
 (f) Except as provided in paragraph (c) above, the Company’s obligation to
indemnify or advance Expenses hereunder to Indemnitee who is or was serving at the request of the Company as a director, officer, employee or agent of any other corporation, partnership, joint venture, trust, employee benefit plan or other
enterprise shall be reduced by any amount Indemnitee has actually received as indemnification or advancement of expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise. 

9. Exception to Right of Indemnification. Notwithstanding any provision in this Agreement, the Company shall not be obligated under
this Agreement to make any indemnity in connection with any claim made against Indemnitee: 
 (a) for which payment has actually been made to
or on behalf of Indemnitee under any insurance policy or other indemnity provision, except with respect to any excess beyond the amount paid under any insurance policy or other indemnity provision, provided that the foregoing shall not affect the
rights or limitations of Indemnitee or the Fund Indemnitors set forth in Section 8(c) above; or 
 (b) for an
accounting of profits made from the purchase and sale (or sale and purchase) by Indemnitee of securities of the Company within the meaning of Section 16(b) of the Securities Exchange Act of 1934, as amended, (the
“Exchange Act”) or similar provisions of state statutory law or common law; or 
 (c) in connection with any Proceeding (or
any part of any Proceeding) initiated by Indemnitee, including any Proceeding (or any part of any Proceeding) initiated by Indemnitee against the Company or its directors, officers, employees or other indemnitees, unless (i) the Board
authorized the Proceeding (or any part of any Proceeding) prior to its initiation, or (ii) the Company provides the indemnification, in its sole discretion, pursuant to the powers vested in the Company under applicable law; or 

(d) with respect to remuneration paid to Indemnitee if it is determined by final judgment or other final adjudication that such
remuneration was in violation of law (and, in this respect, both the Company and Indemnitee have been advised that the SEC believes that indemnification for liabilities arising under the federal securities laws is against public policy and is,
therefore, unenforceable and that claims for indemnification should be submitted to appropriate courts for adjudication, as indicated in the last paragraph of this Section 9); or 

  
 10 

 (e) a final judgment or other final adjudication is made that Indemnitee’s conduct was
in bad faith, knowingly fraudulent or deliberately dishonest or constituted willful misconduct (but only to the extent of such specific determination); or 

(f) in connection with any claim for reimbursement or any recovery policy of the Company by Indemnitee of any bonus or other incentive-based
or equity-based compensation or of any profits realized by Indemnitee from the sale of securities of the Company, as required in each case under the Exchange Act (including any such reimbursements that arise from an accounting restatement of the
Company pursuant to Section 304 of the Sarbanes-Oxley Act or Section 954 of the Dodd-Frank Act, or the payment to the Company of profits arising from the purchase and sale by Indemnitee of securities in violation of Section 306 of the
Sarbanes-Oxley Act)), if Indemnitee is held liable therefor (including pursuant to any settlement); or 
 (g) on account of conduct that is
established by a final judgment as constituting a breach of Indemnitee’s duty of loyalty to the Company or resulting in any personal profit or advantage to which Indemnitee is not legally entitled. 

For purposes of this Section 9, a final judgment or other adjudication may be reached in either the underlying proceeding or action in
connection with which indemnification is sought or a separate proceeding or action to establish rights and liabilities under this Agreement. 

Any provision herein to the contrary notwithstanding, the Company will not be obligated pursuant to the terms of this Agreement to indemnify
Indemnitee or otherwise act in violation of any undertaking appearing in and required by the rules and regulations promulgated under the Securities Act, or in any registration statement filed with the SEC under the Securities Act. Indemnitee
acknowledges that paragraph (h) of Item 512 of Regulation S-K promulgated under the Securities Act currently generally requires the Company to undertake, in connection with any registration statement
filed under the Securities Act, to submit the issue of the enforceability of Indemnitee’s rights under this Agreement in connection with any liability under the Securities Act on public policy grounds to a court of appropriate jurisdiction and
to be governed by any final adjudication of such issue. Indemnitee specifically agrees that any such undertaking will supersede the provisions of this Agreement and to be bound by any such undertaking. 

10. Duration of Agreement. All agreements and obligations of the Company contained herein shall continue during the period Indemnitee
is an officer or director of the Company (or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise) and shall continue thereafter so
long as Indemnitee shall be subject to any Proceeding (or any proceeding commenced under Section 7 hereof) by reason of his Corporate Status, whether or not he is acting or serving in any such capacity at the time any
liability or expense is incurred for which indemnification can be provided under this Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the parties hereto and their respective successors (including any
direct or indirect successor by purchase, merger, consolidation or otherwise to all or substantially all of the business or assets of the Company), assigns, spouses, heirs, executors and personal and legal representatives. 

  
 11 

 11. Security. To the extent requested by Indemnitee and approved by the Board, the
Company may at any time and from time to time provide security to Indemnitee for the Company’s obligations hereunder through an irrevocable bank line of credit, funded trust or other collateral. Any such security, once provided to Indemnitee,
may not be revoked or released without the prior written consent of the Indemnitee. 
 12. Enforcement. 

(a) The Company expressly confirms and agrees that it has entered into this Agreement and assumes the obligations imposed on it hereby in
order to induce Indemnitee to serve as an officer or director of the Company, and the Company acknowledges that Indemnitee is relying upon this Agreement in serving as an officer or director of the Company. 

(b) This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all
prior agreements and understandings, oral, written and implied, between the parties hereto with respect to the subject matter hereof. 
 (c)
The Company shall not seek from a court, or agree to, a “bar order” which would have the effect of prohibiting or limiting the Indemnitee’s rights to receive advancement of expenses under this Agreement. 

13. Definitions. For purposes of this Agreement: 

(a) “Beneficial Owner” has the meaning given to such term in Rule 13d-3 under the
Exchange Act; provided, however, that Beneficial Owner will exclude any Person otherwise becoming a Beneficial Owner by reason of the Company’s stockholders approving a merger of the Company with another entity. 

(b) “Change in Control” means the earliest to occur after the date of this Agreement of any of the following events: 

(i) Acquisition of Stock by Third Party. Any Person is or becomes the Beneficial Owner (as defined above),

(ii) Change in Board. During any period of two consecutive years (not including any period prior to the execution of this
Agreement), individuals who at the beginning of such period constitute the Board, and any new director (other than a director designated by a person who has entered into an agreement with the Company to effect a transaction described in clause (i),
(iii) or (iv) of this definition of Change in Control) whose election by the Board or nomination for election by the Company’s stockholders was approved by a vote of at least two-thirds of the
directors then still in office who either were directors at the beginning of the period or whose election or nomination for election was previously so approved, cease for any reason to constitute at least a majority of the members of the Board; 

 

  
 12 

 (iii) Corporate Transactions. The effective date of a merger or
consolidation of the Company with any other entity, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior to such merger or consolidation continuing to represent (either by
remaining outstanding or by being converted into voting securities of the surviving entity) more than 51% of the combined voting power of the voting securities of the surviving entity outstanding immediately after such merger or consolidation and
with the power to elect at least a majority of the Board or other governing body of such surviving entity; 

(iv) Liquidation. The approval by the Company’s stockholders of a complete liquidation of the Company or an agreement
for the sale or disposition by the Company of all or substantially all of the Company’s assets; and 
 (v) Other
Events. There occurs any other event of a nature that would be required to be reported in response to Item 6(e) of Schedule 14A of Regulation 14A (or a response to any similar item on any similar schedule or form) promulgated under the
