(b) Notwithstanding
the provisions set forth in Section 2(a), one hundred percent (100%) of the Restricted Securities may be Transferred in connection
with or following the occurrence of a Liquidity Event, and Holder or its Permitted Transferees may Transfer the Restricted Securities
during the Lock-Up Period: (A) in the case that Holder is an individual, by gift to the spouse, domestic partner, parent, sibling, child
or grandchild of such Holder or any other natural person with whom such Holder has a relationship by blood, marriage or adoption not
more remote than first cousin, to an estate planning vehicle or to a trust, the beneficiary of which is a member of the individual’s
immediate family, or to a charitable organization; (B) in the case that Holder is an individual, by virtue of laws of descent and distribution
upon death of Holder; (C) in the case that Holder is an individual, pursuant to a qualified domestic relations order, divorce settlement,
divorce decree or separation agreement; (D) to a nominee or custodian of a person to whom a Transfer would be permitted under clauses
(A) through (C) above; (E) to any members, partners, beneficial owners or shareholders of Holder or any Affiliates of Holder; (F) by
virtue of applicable law or Holder’s organizational documents upon liquidation or dissolution of Holder; (G) to Rotor in connection

to purchase Rotor Common Shares or the vesting and/or settlement of Rotor restricted stock or stock-based awards (including options and
awards assumed by Rotor or otherwise issued in exchange for Sarcos Options, Sarcos RSUs or Sarcos RSAs); (I) in payment on a “net
exercise” or “cashless” basis of the exercise or purchase price with respect to the exercise of options to purchase
shares of Rotor Common Shares (including options assumed by Rotor); or (J) in connection
with any court order or order from a Governmental Entity requiring the sale of such Restricted Securities; provided, however,
that in the case of clauses (A) through (F) such transferee must enter into a written agreement with Rotor, in substantially the same
form of this Agreement, stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this
Agreement and shall be deemed to be a Holder for purposes of this Agreement, and there shall be no further Transfer of such Restricted
Securities except in accordance with this Agreement; provided, further, for the avoidance of doubt, a Holder shall not
be limited in filing (or participation in the filing) of a registration statement with the SEC in respect of any restricted stock or
stock-based awards the Transfer of which is or may be necessary to satisfy tax withholding obligations in connection with the vesting
and/or settlement of such restricted stock or stock-based awards.

 

    3

     

    

 

(c) If
any Transfer is made or attempted contrary to the provisions of this Agreement, such purported Transfer shall be null and void ab initio,
and Rotor shall refuse to recognize any such purported transferee of the Restricted Securities as one of its equity holders for any purpose.

 

(d) During
the Lock-up Period, Holder agrees and consents to the entry of stop transfer instructions with Rotor’s transfer agent and registrar
against the transfer of Restricted Securities held by Holder, except in compliance with the foregoing restrictions, and further agrees
that stop transfer orders shall be placed against the Restricted Securities and each certificate or book entry position statement evidencing
any Restricted Securities shall be stamped or otherwise imprinted with a legend in substantially the following form, in addition to any
other applicable legends:

 

“THE
SECURITIES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF APRIL 5,
2021, BY AND AMONG THE ISSUER OF SUCH SECURITIES (THE “ISSUER”), THE ISSUER’S SECURITY HOLDER NAMED THEREIN
AND CERTAIN OTHER PARTIES NAMED THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER
TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”

 

(e) For
the avoidance of any doubt, (i) if and to the extent Holder’s Restricted Securities include issued and outstanding shares of Rotor
Common Shares, Holder shall retain all of its rights as a stockholder of Rotor during the Lock-up Period, including the right to vote
any Restricted Securities that such Holder is entitled to vote, and to receive any dividends and distributions in respect of any Restricted
Securities, and (ii) the restrictions contained in Section 2(a) shall not apply to any Rotor Common Shares or other securities
of Rotor acquired by Holder in open market transactions or in any public or private capital raising transactions of Rotor or otherwise
to any Rotor Common Shares (or other securities of Rotor) other than the Restricted Securities.

 

3. Miscellaneous.

 

(a) Termination
of Merger Agreement. Notwithstanding anything to the contrary contained herein, in the event that the Merger Agreement is terminated
in accordance with its terms prior to the Closing, this Agreement and all rights and obligations of the parties hereunder shall automatically
terminate and be of no further force or effect.

 

(b) Binding
Effect; Assignment. Holder hereby represents and warrants that Holder has full power, capacity and authority to enter into this Agreement.
This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective
permitted successors and assigns. This Agreement and all obligations of Holder are personal to Holder and may not be transferred or delegated
by Holder at any time without the prior written consent of Rotor and Sarcos. Each of Rotor and Sarcos may freely assign any or all of
its rights under this Agreement, in whole or in part, to any successor entity (whether by merger, consolidation, equity sale, asset sale
or otherwise) without obtaining the consent or approval of Holder.

 

(c) Third
Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection with the transactions
contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any person or entity that is not
a party hereto or thereto or a successor or permitted assign of such a party; provided, that Rotor Sponsor, LLC, a Delaware limited
liability company (“Sponsor”), shall be an express third party beneficiary of this Agreement and shall have the right
to enforce the terms of this Agreement directly against Holder as if Sponsor were an original party hereto.

(d) Governing
Law; Jurisdiction; Waiver of Jury Trial; Remedies. This Agreement and all related Proceedings shall be governed by and construed
in accordance with the internal Laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision
or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any jurisdiction
other than the State of Delaware. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO TRIAL BY JURY
OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN ANY WAY CONNECTED WITH OR RELATED OR INCIDENTAL
TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO, IN EACH CASE WHETHER NOW
EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. EACH PARTY HERETO HEREBY AGREES AND CONSENTS THAT
ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY AND THAT THE PARTIES HERETO MAY FILE
A COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE PARTIES HERETO TO THE WAIVER OF THEIR
RIGHT TO TRIAL BY JURY. The parties hereto expressly incorporate by reference Section 8.16 (Jurisdiction) of the Merger Agreement and,
subject to Section 3(j) hereof, Section 8.17 (Remedies) of the Merger Agreement to apply to this Agreement, mutatis mutandis,
with references to the Merger Agreement therein deemed to reference this Agreement and references to the “Parties” thereunder
deemed to reference the parties hereto.

 

(e) Severability.
Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective and valid under applicable
Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under applicable Law, all other
provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance of the transactions contemplated
hereby is not affected in any manner materially adverse to any party hereto. Upon such determination that any term or other provision
of this Agreement is invalid, illegal or unenforceable under applicable Law, the parties hereto shall negotiate in good faith to modify
this Agreement so as to effect the original intent of the parties hereto as closely as possible in an acceptable manner in order that
the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible.

or interpretation of this Agreement. Unless otherwise indicated to the contrary herein by the context or use thereof: (a) the words,

or Sections of this Agreement; and (j) all references to any Law will be to such Law as amended, supplemented or otherwise modified from
time to time. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. Consequently, in the event
an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto,
and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the authorship of any provision of this

(h) Amendments
and Waivers. This Agreement may be amended or modified only with the written consent of Rotor, Sarcos and Holder. The observance
of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or prospectively)
only with the written consent of the party against whom enforcement of such waiver is sought. No failure or delay by a party in exercising

on Behalf of Rotor. In the event that Holder or Holder’s Affiliate serves as a director, officer, employee or other authorized
agent of Rotor or any of its current or future Affiliates, Holder and/or Holder’s Affiliate, as applicable, shall have no authority,

    6

     

    

 

(j) Specific
Performance. Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in the event of
a breach of this Agreement by Holder, money damages will be inadequate and Rotor and Sarcos will have no adequate remedy at law, and
agrees that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by Holder in
accordance with their specific terms or were otherwise breached. Accordingly, each of Rotor and Sarcos (or Sponsor on their behalf) shall
be entitled to an injunction or restraining order to prevent breaches of this Agreement by Holder and to enforce specifically the terms
and provisions hereof, without the requirement to post any bond or other security or to prove that money damages would be inadequate,
this being in addition to any other right or remedy to which such party may be entitled under this Agreement, at law or in equity.

 

(k) Entire
Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties hereto with respect to the
subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the parties is
expressly canceled; provided that, for the avoidance of doubt, the foregoing shall not affect the rights and obligations
of the parties, if any, under the Merger Agreement or any Ancillary Documents. Notwithstanding the foregoing, nothing in this Agreement
shall limit any of the rights or remedies of Rotor and Sarcos or any of the obligations of Holder under any other agreement between Holder
and Rotor or Sarcos or any certificate or instrument executed by Holder in favor of Rotor or Sarcos, and nothing in any other agreement,
certificate or instrument shall limit any of the rights or remedies of Rotor or Sarcos or any of the obligations of Holder under this
Agreement.

 

(l) Further
Assurances. From time to time, at another party’s written request and without further consideration (but at the requesting
party’s reasonable cost and expense), each party shall execute and deliver such additional documents and take all such further
action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

 

(m) Counterparts;
Electronic Signatures.  This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original,
but all of which shall constitute one and the same agreement. The words “execution,” “signed,” “signature,”
and words of like import in this Agreement or in any other certificate, agreement or document related to this Agreement shall include
images of manually executed signatures transmitted by facsimile or other electronic format (including, “pdf”, “tif”
or “jpg”) and other electronic signatures (including DocuSign and AdobeSign). The use of electronic signatures and electronic
records (including, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall
be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based record-keeping system
to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the
Delaware Uniform Electronic Transactions Act and any other applicable law. Minor variations in the form of the signature page, including
footers from earlier versions of this Agreement or any such other document shall be disregarded in determining the parties’ intent
or the effectiveness of such signature.

2.
Lock-up Provisions.

 

(a)  Subject
to Section 2(b), Holder agrees that it shall not Transfer any Restricted Securities beginning on the Closing Date and ending
on the close of business on the one (1) year anniversary of the Closing Date (such period with respect to Holder’s applicable
Restricted Securities, the “Lock-Up Period”).

 

(b)  Notwithstanding
the provisions set forth in Section 2(a), one hundred percent (100%) of the Restricted Securities may be Transferred in
connection with or following the occurrence of a Liquidity Event, and Holder or its Permitted Transferees may Transfer the
Restricted Securities during the Lock-Up Period: (A) in the case that Holder is an individual, by gift to the spouse, domestic
partner, parent, sibling, child or grandchild of such Holder or any other natural person with whom such Holder has a relationship by
blood, marriage or adoption not more remote than first cousin, to an estate planning vehicle or to a trust, the beneficiary of which
is a member of the individual’s immediate family, or to a charitable organization; (B) in the case that Holder is an
individual, by virtue of laws of descent and distribution upon death of Holder; (C) in the case that Holder is an individual,
pursuant to a qualified domestic relations order, divorce settlement, divorce decree or separation agreement; (D) to a nominee or
custodian of a person to whom a Transfer would be permitted under clauses (A) through (C) above; (E) to any members, partners,
beneficial owners or shareholders of Holder or any Affiliates of Holder; (F) by virtue of applicable law or Holder’s
organizational documents upon liquidation or dissolution of Holder; or (G) in connection with any court order or order from a
Governmental Entity requiring the sale of such Restricted Securities; provided, however, that in the case of clauses
(A) through (F) such transferee must enter into a written agreement with Rotor, in substantially the same form of this Agreement,
stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this Agreement and shall
be deemed to be a Holder for purposes of this Agreement, and there shall be no further Transfer of such Restricted Securities except
in accordance with this Agreement.

 

(c)  If
any Transfer is made or attempted contrary to the provisions of this Agreement, such purported Transfer shall be null and void ab
initio, and Rotor shall refuse to recognize any such purported transferee of the Restricted Securities as one of its equity holders
for any purpose.

 

(d)  During the Lock-up Period,
Holder agrees and consents to the entry of stop transfer instructions with Rotor’s transfer agent and registrar against the transfer
of Restricted Securities held by Holder, except in compliance with the foregoing restrictions, and further agrees that stop transfer
orders shall be placed against the Restricted Securities and each certificate or book entry position statement evidencing any Restricted
Securities shall be stamped or otherwise imprinted with a legend in substantially the following form, in addition to any other applicable
legends:

 

“THE SECURITIES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF APRIL 5, 2021, BY AND AMONG THE ISSUER
OF SUCH SECURITIES (THE “ISSUER”), THE ISSUER’S SECURITY HOLDER NAMED THEREIN AND CERTAIN OTHER PARTIES NAMED
THEREIN, AS AMENDED. A COPY OF SUCH LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN
REQUEST.”

 

(e)  For
the avoidance of any doubt, (i) if and to the extent Holder’s Restricted Securities include issued and outstanding shares of
Rotor Common Shares, Holder shall retain all of its rights as a stockholder of Rotor during the Lock-up Period, including the right
to vote any Restricted Securities that such Holder is entitled to vote, and to receive any dividends and distributions in respect of
any Restricted Securities, and (ii) the restrictions contained in Section 2(a) shall not apply to any Rotor Common Shares or
other securities of Rotor acquired by Holder in open market transactions or in any public or private capital raising transactions of
Rotor or otherwise to any Rotor Common Shares (or other securities of Rotor) other than the Restricted Securities.

 

3.
Waiver of Preemptive Rights. Holder hereby agrees that the execution and delivery of this Agreement will constitute an irrevocable
waiver of all of its rights under Section 4 of the Amended and Restated Investors’ Rights Agreement, dated as of January 31, 2020,
by and among Sarcos and certain investors party thereto (as amended, the “Investors’ Rights Agreement”) with
respect to any issuance and sale by Sarcos of any New Securities (as defined in the Investors’ Rights Agreement), including the
waiver of (i) the right to purchase any New Securities and (ii) the 30-day notice requirement set forth therein (the “Waiver”),
and agrees that he, she or it will not purchase any New Securities issued and sold by Sarcos at any time prior to the Closing. Holder
acknowledges and agrees that the Waiver is a valid and binding obligation of Holder, and is enforceable in accordance with its terms.
Holder agrees that he, she or it shall execute and deliver such additional documents and take such additional action as may be necessary
or desirable to effectuate the provisions and purposes of the Waiver.

 

    3

     

    

 

4.
Miscellaneous.

 

(a)
 Termination of Merger Agreement. Notwithstanding anything to the contrary contained herein, in the event that
the Merger Agreement is terminated in accordance with its terms prior to the Closing, this Agreement and all rights and obligations
of the parties hereunder shall automatically terminate and be of no further force or effect.

 

(b)  Binding
Effect; Assignment. Holder hereby represents and warrants that Holder has full power, capacity and authority to enter into this
Agreement. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and
their respective permitted successors and assigns. This Agreement and all obligations of Holder are personal to Holder and may not
be transferred or delegated by Holder at any time without the prior written consent of Rotor and Sarcos. Each of Rotor and Sarcos
may freely assign any or all of its rights under this Agreement, in whole or in part, to any successor entity (whether by merger,
consolidation, equity sale, asset sale or otherwise) without obtaining the consent or approval of Holder.

 

(c)  Third
Parties. Nothing contained in this Agreement or in any instrument or document executed by any party in connection with the
transactions contemplated hereby shall create any rights in, or be deemed to have been executed for the benefit of, any person or
entity that is not a party hereto or thereto or a successor or permitted assign of such a party; provided, that Rotor
Sponsor, LLC, a Delaware limited liability company (“Sponsor”), shall be an express third party beneficiary of
this Agreement and shall have the right to enforce the terms of this Agreement directly against Holder as if Sponsor were an
original party hereto.

 

(d)  Governing
Law; Jurisdiction; Waiver of Jury Trial; Remedies. This Agreement and all related Proceedings shall be governed by and construed
in accordance with the internal Laws of the State of Delaware, without giving effect to any choice of law or conflict of law
provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the Law of any
jurisdiction other than the State of Delaware. EACH PARTY HERETO HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY LAW, ANY RIGHT TO
TRIAL BY JURY OF ANY CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION (I) ARISING UNDER THIS AGREEMENT OR (II) IN ANY WAY CONNECTED WITH OR
RELATED OR INCIDENTAL TO THE DEALINGS OF THE PARTIES HERETO IN RESPECT OF THIS AGREEMENT OR ANY OF THE TRANSACTIONS RELATED HERETO,
IN EACH CASE WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER IN CONTRACT, TORT, EQUITY, OR OTHERWISE. EACH PARTY HERETO
HEREBY AGREES AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION, OR CAUSE OF ACTION SHALL BE DECIDED BY COURT TRIAL WITHOUT A JURY
AND THAT THE PARTIES HERETO MAY FILE A COUNTERPART OF A COPY OF THIS AGREEMENT WITH ANY COURT AS WRITTEN EVIDENCE OF THE CONSENT OF
THE PARTIES HERETO TO THE WAIVER OF THEIR RIGHT TO TRIAL BY JURY. The parties hereto expressly incorporate by reference Section 8.16
(Jurisdiction) of the Merger Agreement and, subject to Section 4(j) hereof, Section 8.17 (Remedies) of the Merger Agreement to apply
to this Agreement, mutatis mutandis, with references to the Merger Agreement therein deemed to reference this Agreement and
references to the “Parties” thereunder deemed to reference the parties hereto.

 

    4

     

    

 

(e)  Severability. Whenever possible, each provision of this Agreement will be interpreted in such a manner as to be effective
and valid under applicable Law, but if any term or other provision of this Agreement is held to be invalid, illegal or unenforceable under
applicable Law, all other provisions of this Agreement shall remain in full force and effect so long as the economic or legal substance
of the transactions contemplated hereby is not affected in any manner materially adverse to any party hereto. Upon such determination
that any term or other provision of this Agreement is invalid, illegal or unenforceable under applicable Law, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original intent of the parties hereto as closely as possible in an
acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent
possible.

 

(f)  Construction;
Interpretation. The headings set forth in this Agreement are inserted for convenience only and shall not affect in any way the
meaning or interpretation of this Agreement. Unless otherwise indicated to the contrary herein by the context or use thereof: (a)
the words, “herein,” “hereto,” “hereof” and words of similar import refer to this Agreement as a
whole, and not to any particular section, subsection, paragraph, subparagraph or clause set forth in this Agreement; (b) masculine
gender shall also include the feminine and neutral genders, and vice versa; (c) words importing the singular shall also include the

exclusive; (g) the words “writing”, “written” and comparable terms refer to printing, typing and other means
of reproducing words (including electronic media) in a visible form; (h) the word “extent” in the phrase “to the

(i) all references to Articles or Sections are to Articles or Sections of this Agreement; and (j) all references to any Law will be
to such Law as amended, supplemented or otherwise modified from time to time. The parties hereto have participated jointly in the
negotiation and drafting of this Agreement. Consequently, in the event an ambiguity or question of intent or interpretation arises,
this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise
favoring or disfavoring any party by virtue of the authorship of any provision of this Agreement.

(h)  Amendments
and Waivers. This Agreement may be amended or modified only with the written consent of Rotor, Sarcos and Holder. The observance
of any term of this Agreement may be waived (either generally or in a particular instance, and either retroactively or
prospectively) only with the written consent of the party against whom enforcement of such waiver is sought. No failure or delay by
a party in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or
provision of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of
any such term, condition, or provision.

 

(i)  
Authorization on Behalf of Rotor. In the event that Holder or Holder’s Affiliate serves as a director, officer, employee
or other authorized agent of Rotor or any of its current or future Affiliates, Holder and/or Holder’s Affiliate, as
applicable, shall have no authority, express or implied, to act or make any determination on behalf of Rotor or any of its current
or future Affiliates in connection with this Agreement to which Holder is party or any dispute or Proceeding with respect
hereto.

 

    6

     

    

 

(j)  
Specific Performance. Holder acknowledges that its obligations under this Agreement are unique, recognizes and affirms that in
the event of a breach of this Agreement by Holder, money damages will be inadequate and Rotor and Sarcos will have no adequate
remedy at law, and agrees that irreparable damage would occur in the event that any of the provisions of this Agreement were not
performed by Holder in accordance with their specific terms or were otherwise breached. Accordingly, each of Rotor and Sarcos (or
Sponsor on their behalf) shall be entitled to an injunction or restraining order to prevent breaches of this Agreement by Holder and
to enforce specifically the terms and provisions hereof, without the requirement to post any bond or other security or to prove that
money damages would be inadequate, this being in addition to any other right or remedy to which such party may be entitled under
this Agreement, at law or in equity.

 

(k)  Entire
Agreement. This Agreement constitutes the full and entire understanding and agreement among the parties hereto with respect to
the subject matter hereof, and any other written or oral agreement relating to the subject matter hereof existing between the
parties is expressly canceled; provided that, for the avoidance of doubt, the foregoing shall not affect the rights and
obligations of the parties, if any, under the Merger Agreement or any Ancillary Documents. Notwithstanding the foregoing, nothing in
this Agreement shall limit any of the rights or remedies of Rotor and Sarcos or any of the obligations of Holder under any other
agreement between Holder and Rotor or Sarcos or any certificate or instrument executed by Holder in favor of Rotor or Sarcos, and
nothing in any other agreement, certificate or instrument shall limit any of the rights or remedies of Rotor or Sarcos or any of the
obligations of Holder under this Agreement.

 

(l)  
Further Assurances. From time to time, at another party’s written request and without further consideration (but at the
requesting party’s reasonable cost and expense), each party shall execute and deliver such additional documents and take all
such further action as may be reasonably necessary to consummate the transactions contemplated by this Agreement.

 

(m)  
Counterparts; Electronic Signatures.  This Agreement may be executed in one or more counterparts, each of which shall be
deemed to be an original, but all of which shall constitute one and the same agreement. The words “execution,”
“signed,” “signature,” and words of like import in this Agreement or in any other certificate, agreement or
document related to this Agreement shall include images of manually executed signatures transmitted by facsimile or other electronic
format (including, “pdf”, “tif” or “jpg”) and other electronic signatures (including DocuSign
and AdobeSign). The use of electronic signatures and electronic records (including, any contract or other record created, generated,
sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a
manually executed signature or use of a paper-based record-keeping system to the fullest extent permitted by applicable law,
including the Federal Electronic Signatures in Global and National Commerce Act, the Delaware Uniform Electronic Transactions Act
and any other applicable law. Minor variations in the form of the signature page, including footers from earlier versions of this
Agreement or any such other document shall be disregarded in determining the parties’ intent or the effectiveness of such
signature.
