AGREEMENT


 


1.              
TENDER OFFER.


 


1.1              
Commencement of Tender Offer. On the terms and subject to the conditions of this Agreement, the Company and
ACM shall commence the Tender Offer as soon as reasonably practicable on or after the date of effectiveness of the Company’s proxy
statement filed in connection with the Business Combination.


 


1.2              
Conduct of Tender Offer. The obligations of the Company and ACM to accept for payment and pay for shares of
Common Stock tendered pursuant to the Tender Offer shall be subject to the terms and conditions set forth in the Offer Documents, and
such obligations shall be several, not joint, obligations of each of the Company and ACM; provided that, in the event ACM is for
any reason unable to consummate its obligations under the Tender Offer, the Company shall acquire all shares tendered in accordance with
the Tender Offer, which, for the avoidance of doubt, shall not relieve ACM of its obligation to purchase the Maximum Share Amount hereunder.
Neither Party may effect any amendment, extension, termination, waiver, or other change to the terms and conditions of the Tender Offer,
or announce that it is taking any such action, without the prior written consent of the other Party.


 


1.3              
SEC Filings. As soon as reasonably practicable on or after the date of filing of the Company’s registration
statement on Form S-4 (the “Registration Statement on Form S-4”) containing its preliminary proxy statement in connection
with the Business Combination, the Company shall file with the United States Securities and Exchange Commission (the “SEC”)
a joint Tender Offer Statement on Schedule TO (together with all amendments thereto, the “Schedule TO”). As soon as
reasonably practicable on or after the date of effectiveness of the Registration Statement on Form S-4 containing the Company’s
definitive proxy statement filed in connection with the Business Combination, the Company and ACM shall file with the SEC any further
amendments to the Schedule TO as then necessary or appropriate to reflect the finalization of the terms and timing of the Tender Offer
and commence the Tender Offer on the date of such filing. Each of the Company and ACM agrees that their respective portions of the Schedule
TO and the other Offer Documents, on the date filed with the SEC and on the date first published, sent, or given to the Company’s
stockholders, will not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, except
that no representation is made by ACM with respect to written information supplied by the Company or any of its Affiliates specifically
for inclusion in the Offer Documents (or any document incorporated by reference in the Offer Documents) and no representation is made
by the Company with respect to written information supplied by ACM or any of its Affiliates specifically for inclusion in the Offer Documents
(or any document incorporated by reference in the Offer Documents). The Company further agrees to take all steps necessary (and ACM shall
cooperate with the Company) to cause the Offer Documents to be filed with the SEC and to be disseminated to the Company’s stockholders,
in each case, as and to the extent required by applicable federal securities laws. Each of the Company and ACM agrees promptly to correct
or supplement any information provided by it for use in the Schedule TO and in the other Offer Documents if and to the extent that it
shall have become false and misleading in any material respect, and the Company further agrees to take all steps necessary (and ACM shall
cooperate with the Company) to cause the Offer Documents as so corrected to be filed with the SEC and to be disseminated to the Company’s
stockholders, in each case, as and to the extent required by applicable federal securities laws. Each of the Company and ACM and their
respective counsel shall be given a reasonable opportunity to review and comment on the Schedule TO and the other Offer Documents prior
to their filing with the SEC or dissemination to stockholders of the Company. In addition, each Party agrees to provide the other Party
and its respective counsel with any comments or other communications that such Party or its counsel may receive from time to time from
the SEC or its staff with respect to the Tender Offer or the Offer Documents promptly after the receipt of such comments or other communications.
Subject to Section 9.3, each of the Company and ACM agree to use commercially reasonable efforts to cooperate with each other to
amend this Agreement, the Offer Documents or any other agreements entered into in connection with the transactions contemplated by this
Agreement (collectively, the “Transaction Documents”) as a result of any comments or other communications received
from the SEC or its staff with respect to the Tender Offer as may be required; provided that any such amendment shall include those terms
that come closest to expressing the intention of the Parties as set forth in the Transaction Documents then in effect.

1.4              
Offer Documents. The Offer Documents shall provide that the Company shall direct its transfer agent to credit
shares of Common Stock purchased by ACM to ACM’s or its designated broker-dealer account or accounts without any legends restricting
further transfers of such shares of Common Stock by ACM.


 


2.                
AGREEMENT TO PURCHASE MAXIMUM SHARE AMOUNT.If, upon completion of the Tender Offer, ACM has not purchased the
Maximum Share Amount pursuant to the Tender Offer, then ACM and the Company shall enter into a subscription agreement, substantially in
the form attached hereto as Exhibit A, to purchase an amount of shares of Common Stock equal to the difference of the Maximum Share
Amount less the amount of shares of Common Stock purchased by ACM pursuant to the Tender Offer.


 


3.               
AVAILABLE FUNDS; SOLVENCY.


 


3.1              
Available Funds. ACM has, and upon consummation of the Tender Offer will have, available cash resources in
amounts sufficient (i) to purchase the Maximum Share Amount tendered in the Tender Offer and to satisfy all other payments required by
the Transaction Documents (whether payable before, at, or after consummation of the Tender Offer), and (ii) to otherwise consummate the
Tender Offer. ACM has not incurred any obligation, commitment, restriction, or other liability of any kind, and is not contemplating or
aware of any obligation, commitment, restriction, or other liability of any kind, in either case which would impair or adversely affect
such resources, funds, or capabilities.


 


3.2              
Solvency. Upon consummation of the Tender Offer, ACM will (i) be solvent, (ii) be able to pay its debts as
such debts become due, (iii) have capital sufficient to carry out its business as now contemplated, and (iv) own assets and properties
having a value both at fair market valuation and at fair saleable value in the ordinary course of business greater than the amount required
to pay its indebtedness and other obligations as the same mature and become due.


 


4.               
EXPENSES.The Company shall bear all expenses incurred thereby in connection with this Agreement and the Tender
Offer, including all legal and accounting fees, SEC filing fees, and expenses and fees of financial printers, information agents and depositaries.
The Company shall also bear (or reimburse ACM, as the case may be) all reasonable, documented out-of-pocket expenses (including, but not
limited to, legal fees) in connection with this Agreement and the Tender Offer incurred by ACM not to exceed $50,000 in the aggregate.
For the avoidance of duplication, the Company shall not bear or reimburse ACM hereunder for any expenses born or reimbursed by the Company
in connection with the FPA.


 


5.                
INDEMNIFICATION.


 


5.1              
Company Indemnification. To the extent permitted by law, the Company will indemnify and hold harmless ACM
and its Affiliates and each Person, if any, who controls (within the meaning of the Securities Act, as defined below) ACM or any of its
Affiliates against any Losses to which any of the foregoing Persons may become subject:


 






    3


     


    

 


(a)               
under the Securities Act of 1933, as amended (the “Securities Act”), the Exchange Act, or other federal
or state law, insofar as such Losses arise out of or are based upon any of the following statements, omissions, or violations: (i) any
untrue statement or alleged untrue statement of a material fact contained in the Schedule TO or the other Offer Documents or any exhibits
or any amendments or supplements thereto, or any document incorporated by reference therein; (ii) the omission or alleged omission
to state therein a material fact (other than any fact pertaining to ACM or any of its Affiliates) required to be stated in the Schedule
TO or the other Offer Documents or any exhibits or any amendments or supplements thereto, or any document incorporated by reference therein,
or necessary to make the statements therein not misleading; and/or (iii) any violation or alleged violation by the Company of the
Securities Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange
Act, or any state securities law; and the Company will pay to ACM and its Affiliates and each Person, if any, who controls ACM (or any
of its Affiliates) within the meaning of the Securities Act any legal or other expenses reasonably incurred by them in connection with
investigating or defending any such Losses; provided, however, that the Company shall not be liable in any such case for
any such Losses to the extent that they arise out of or are based upon a violation that occurs in reliance upon and in conformity with
written information furnished by or on behalf of ACM or any of its Affiliates expressly for use in connection with the Tender Offer (including
information incorporated by reference to any filings made by ACM or its Affiliates with the SEC); and


 


(b)               
arising from or relating to ACM being an offeror in the Tender Offer with respect to any liability to purchase more than
the Maximum Share Amount (the “ACM Share Indemnity”).


 


5.2              
ACM Indemnification. To the extent permitted by law, ACM will indemnify and hold harmless the Company and
its Affiliates against any Losses to which any of the foregoing Persons may become subject under the Securities Act, the Exchange Act,
or other federal or state law, insofar as such Losses arise out of or are based upon any of the following statements, omissions, or violations:
(i) any untrue statement or alleged untrue statement of a material fact contained in the Schedule TO or the other Offer Documents
or any exhibits or any amendments or supplements thereto, or any document incorporated by reference therein that occurs in reliance upon
and in conformity with written information furnished by ACM or any of its Affiliates expressly for use in connection with the Tender Offer
(including information incorporated by reference to any filings made by ACM or its Affiliates with the SEC); (ii) the omission or
alleged omission to state therein a material fact pertaining to ACM or any of its Affiliates required to be stated in the Schedule TO
or the other Offer Documents or any exhibits or any amendments or supplements thereto, or any document incorporated by reference therein,
or necessary to make the statements therein not misleading; and/or (iii) any violation or alleged violation by ACM of the Securities
Act, the Exchange Act, any state securities law, or any rule or regulation promulgated under the Securities Act, the Exchange Act, or
any state securities law; and ACM will pay to the Company and its Affiliates any legal or other expenses reasonably incurred by them in
connection with investigating or defending any such Losses; provided, however, that ACM shall not be liable in any such case for
any such Losses to the extent that they arise out of or are based upon a violation that occurs in reliance upon and in conformity with
written information furnished by or on behalf of the Company or any of its Affiliates expressly for use in connection with the Tender
Offer (including information incorporated by reference to any filings made by the Company or its Affiliates with the SEC).


 


5.3              
Indemnification Notice. Promptly after receipt by any Person entitled to seek indemnification pursuant to
Section 6.1 or 6.2 (an “Indemnified Party”) of notice of the commencement of any action (including any
governmental action), such Indemnified Party shall, if a claim in respect thereof is to be made against any Party required to provide
indemnification pursuant to Section 6.1 or 6.2 (an “Indemnifying Party”), deliver to the Indemnifying
Party a written notice of the commencement thereof and the Indemnifying Party shall have the right to participate in and, to the extent
the Indemnifying Party so desires, jointly with any other Indemnifying Party similarly noticed, to assume the defense thereof with counsel
mutually satisfactory to the Parties; provided, however, that an Indemnified Party (together with all other Indemnified
Parties that may be represented without conflict by one counsel) shall have the right to retain one separate counsel, with the fees and
expenses to be paid by the Indemnifying Party, if representation of such Indemnified Party by the counsel retained by the Indemnifying
Party would be inappropriate due to actual or potential differing interests between such Indemnified Party and any other party represented
by such counsel in such proceeding. The failure to deliver written notice to the Indemnifying Party within a reasonable time of the commencement
of any such action, if prejudicial to its ability to defend such action, shall relieve such Indemnifying Party of any liability to the
Indemnified Party under this Section 6, but the omission to deliver written notice to the Indemnifying Party will not relieve
it of any liability that it may have to any Indemnified Party otherwise than under this Section 6.


 






    4


     


    

 


5.4              
Contribution. If the indemnification provided for in this Section 5 is held by a court of competent
jurisdiction to be unavailable to an Indemnified Party with respect to any Losses referred to therein, then the Indemnifying Party, in
lieu of indemnifying such Indemnified Party hereunder, shall contribute to the amount paid or payable by such Indemnified Party as a result
of such Losses in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party, on the one hand, and of the
Indemnified Party, on the other hand, in connection with the statements or omissions that resulted in such Losses as well as any other
relevant equitable considerations. The relative fault of the Indemnifying Party and of the Indemnified Party shall be determined by reference
to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission to state a material fact relates
to information supplied by the Indemnifying Party or by the Indemnified Party and the Parties’ relative intent, knowledge, access
to information, and opportunity to correct or prevent such statement or omission. The amount paid or payable by an Indemnified Party as
a result of the Losses or action in respect thereof, referred to above in this Section 5.4 shall be deemed to include, for
purposes of this Section 5.4, any legal or other expenses reasonably incurred by such Indemnified Party in connection with
investigating or defending any such action or claim. Notwithstanding anything herein to the contrary, this Section 5.4 shall
not be applicable to the ACM Share Indemnity.


 


5.5              
Survival. The obligations of the Company and ACM under this Section 5 shall survive the completion
of the Tender Offer.


 


6.                  
CONDITIONS.The obligations of the Parties to consummate the transactions contemplated by this Agreement are subject
to each of the Parties having executed and entered into the FPA concurrently with this Agreement. The obligations of ACM are subject to
(i) the execution and delivery of the Business Combination Agreement, in the form set forth as Exhibit B hereto, on the date hereof and
(ii) neither the Business Combination Agreement nor any other material agreement to which the Company is a party, which agreement relates
to the Business Combination, shall have been amended, modified or waived at any time prior to the completion of the Tender Offer without
the prior written consent of ACM (such consent not to be unreasonably withheld, conditioned or delayed).


 


7.                  
TERMINATION.This Agreement may be terminated by (i) the mutual written consent of the Company and ACM, (ii) either
the Company, ACM or Essentium if any Governmental Entity shall have entered, issued, enacted or promulgated an Order or taken any other
action permanently enjoining, preventing, restraining, making unlawful or otherwise prohibiting the transactions contemplated by this
Agreement and such Order or other action shall have become final and non-appealable, (iii) either the Company, ACM or Essentium if the
Business Combination Agreement is terminated prior to the closing of the Business Combination or (iv) either the Company, ACM or Essentium,
if (a) the Registration Statement on Form S-4 is not declared effective by the SEC by the date that is 120 days after the date of the
Business Combination Agreement, or (b) the Parties do not launch the Tender Offer by the date that is 120 days after the date of this
Agreement; provided, that the right to terminate this Agreement pursuant to this Section 7 shall not be available to a Party if
such Party’s breach of its obligations under this Agreement or the Business Combination Agreement shall have proximately caused
the entry, issuance, enactment or promulgation of such Order or the occurrence of such other action or delay.


 


8.                  
MISCELLANEOUS.


 


8.1              
Successors and Assigns. Except as otherwise provided herein, this Agreement shall be binding upon, inure to
the benefit of, and be enforceable by, the Parties and their respective successors and assigns. Nothing in this Agreement, express or
implied, is intended to confer upon any party, other than the Parties and their respective successors and assigns, any rights, remedies,
obligations, or liabilities under or by reason of this Agreement, except as expressly provided in this Agreement. Neither this Agreement
nor any of the rights, interests, or obligations hereunder shall be assigned by any of the Parties (whether by operation of law or otherwise)
without the prior written consent of the other Party, except that ACM may (a) assign, in its sole discretion, all (but not less than
all) of its rights and interests hereunder to any of its Affiliates and (b) grant a security interest in or otherwise pledge any
or all of its rights and interests hereunder in favor of one or more institutional financing sources.

by each Party. Except as otherwise permitted in this Agreement, the terms or conditions of this Agreement may not be waived, unless set
forth in a writing signed by the Party entitled to the benefits thereof. No waiver of any of the provisions of this Agreement shall be
deemed or shall constitute a waiver of such provision at any time in the future or a waiver of any other provision hereof. The rights
and remedies of the Parties are cumulative and not alternative. Except as otherwise provided in this Agreement, neither the failure nor
any delay by a Party in exercising any right, power, or privilege under this Agreement will operate as a waiver of such right, power,

such right, power, or privilege or the exercise of any other right, power, or privilege.

8.4              
Severability. Any term or provision of this Agreement that is held by a court of competent jurisdiction or
other authority to be invalid, void, or unenforceable in any situation in any jurisdiction shall not affect the validity or enforceability
of the remaining terms and provisions hereof or the validity or enforceability of the offending term or provision in any other situation
or in any other jurisdiction. If the final judgment of a court of competent jurisdiction or other authority declares that any term or
provision hereof is invalid, void, or unenforceable, the Parties agree that the court making such determination shall have the power to
reduce the scope, duration, area, or applicability of the term or provision, to delete specific words or phrases, or to replace any invalid,
void, or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the
intention of the invalid or unenforceable term or provision.


 


8.5              
Governing Law. This Agreement shall be governed by the laws of the State of Delaware, without regard to conflict
of laws principles.


 


8.6              
Choice of Venue. Any action, suit, or proceeding arising out of or relating to this Agreement may be brought
in the state or federal courts of the State of Delaware, and each Party irrevocably submits to the exclusive jurisdiction of each such
court in any such action, suit, or proceeding, waives any objection it may now or hereafter have to venue or to convenience of forum,
agrees that all claims in respect of such action, suit, or proceeding shall be heard and determined only in such court, and agrees not
to bring any action, suit, or proceeding arising out of or relating to this Agreement or any of the transactions contemplated by this
Agreement in any other court. The Parties agree that either or both of them may file a copy of this paragraph with any court as written
evidence of the knowing, voluntary, and bargained agreement between the Parties irrevocably to waive any objections to venue or convenience
of forum.


 


8.7              
Entire Agreement. This Agreement and any documents related hereto constitute the full and entire understanding
and agreement between the Parties with regard to the subject matter hereof.


 


8.8              
Counterparts. This Agreement may be executed in two or more counterparts (including by facsimile, .pdf, or
similar means of electronic communication), each of which shall be deemed an original, but all of which together shall constitute one
and the same instrument.


 


8.9              
Specific Performance. ACM and the Company each agree that irreparable damage would occur in the event that
any of the provisions of this Agreement were not performed by them in accordance with the terms hereof and that each Party shall be entitled
to seek specific performance of the terms hereof, in addition to any other remedy at law or equity. Each Party expressly waives any requirement
that the other Party obtain any bond or provide any indemnity in connection with any action seeking injunctive relief or specific enforcement
of the provisions of this Agreement.


 


8.10          
Third Party Beneficiary. This Agreement shall inure solely to the benefit of and be binding upon the Parties
hereto; provided, that Essentium shall be a third party beneficiary hereof and may enforce the provisions in Section 7 and Section
8.3 to the extent provided herein as if it were a Party hereto.


 


8.11         
Certain Actions Under the Business Combination Agreement. If ACM shall enter
into a subscription agreement pursuant to Section 2, prior to the closing of the Business Combination, the Company agrees that
it shall not consent to (i) any action of Essentium requiring such consent pursuant to Section 5.1(b) of the Business Combination Agreement
if such action would reasonably be expected to materially adversely affect the economic benefits that ACM would expect to receive under
the Subscription Agreement or (ii) take any action prohibited by Section 5.9(b) of the Business Combination Agreement, in each case without
having received ACM’s prior written consent.
