Exhibit 10.1


 


SUBSCRIPTION AGREEMENT


 


This SUBSCRIPTION AGREEMENT
(this “Subscription Agreement”) is entered into on December 12, 2019, by and between B. Riley Principal Merger
Corp., a Delaware corporation (“BRPM”), and the undersigned subscriber (the “Subscriber”).


 


WHEREAS, concurrently
with the execution of this Subscription Agreement, BRPM is entering into an agreement (the “Business Combination Agreement”)
for a business combination (the “Business Combination”) with Alta Equipment Holdings, Inc., a Michigan corporation
(the “Target”); and


 


WHEREAS, in connection
with the Business Combination, the Subscriber desires to subscribe for and purchase from BRPM, immediately prior to the consummation
of the Business Combination, that number of shares of BRPM’s Class A common stock, par value $0.0001 per share (“Common
Stock”), set forth on the signature page hereto (the “Subscribed Shares”), for a purchase price of
$10.00 per share (the “Per Share Price” and the aggregate of such Per Share Price for all Subscribed Shares
being referred to herein as the “Purchase Price”), in a private placement (the “Private Placement”),
and BRPM desires to issue and sell to the Subscriber the Subscribed Shares in consideration of the payment of the Purchase Price
by or on behalf of Subscriber to the Company.


 


NOW, THEREFORE, in
consideration of the foregoing and the mutual representations, warranties and covenants, and subject to the conditions, herein
contained, and intending to be legally bound hereby, the parties hereto hereby agree as follows:


 


1. Subscription.


 


(a) Subject
to the terms and conditions hereof, at the Closing (as defined below), the Subscriber hereby agrees to subscribe for and purchase,
and BRPM hereby agrees to issue and sell to the Subscriber, upon the payment of the Purchase Price, the Subscribed Shares (such
subscription and issuance, the “Subscription”).


 


(b) BRPM
shall issue an additional number of shares of Common Stock to the Subscriber equal to the product of the number of Subscribed Shares
purchased by the Subscriber multiplied by 5/95 (the “Incentive Shares”). No fractional Incentive Shares will
be issued, and the Company will round down the number of Incentive Shares to be issued to the Subscriber down to the nearest whole
number.


 


(c) For
each 100,000 Subscribed Shares purchased by the Subscriber, the Subscriber shall also receive from BRPM 37,500 warrants to purchase
shares of Common Stock (the “Incentive Warrants”). Each whole Incentive Warrant shall be exercisable for one
share of Common Stock at a price of $11.50 per share and shall have identical terms to the warrants included as part of the Company’s
units issued in BRPM’s initial public offering (the “IPO”). No fractional Incentive Warrants will be issued,
and the Company will round the number of Incentive Warrants to be issued to the Subscriber down to the nearest whole number.


 






     


     


    

 


2. Closing.


 


(a) The
consummation of the Subscription contemplated hereby (the “Closing”) shall occur on the Closing Date immediately
prior to the consummation of the Business Combination.


 


(b) At
least five (5) Business Days before the anticipated Closing Date, BRPM shall deliver written notice to the Subscriber (the “Closing
Notice”) specifying (i) the anticipated Closing Date and (ii) the wire instructions for delivery of the Purchase Price
to BRPM. No later than two (2) Business Days after receiving the Closing Notice, the Subscriber shall deliver to BRPM such information
as is reasonably requested in the Closing Notice in order for BRPM to issue the Subscribed Shares, Incentive Shares and Incentive
Warrants to the Subscriber. The Subscriber shall deliver to BRPM, on or prior to 8:00 a.m. (Eastern time) (or as soon as practicable
after BRPM or its transfer agent (the “Transfer Agent”) delivers evidence of the issuance to the Subscriber
of the Subscribed Shares, Incentive Shares and Incentive Warrants on and as of the Closing Date) on the Closing Date the Purchase
Price in cash via wire transfer to the account specified in the Closing Notice against (and concurrently with) delivery by BRPM
to the Subscriber of (i) the Subscribed Shares, Incentive Shares and Incentive Warrants in book entry form, free and clear of any
liens or other restrictions (other than those arising under this Subscription Agreement or state or federal securities laws), in
the name of the Subscriber (or its nominee in accordance with its delivery instructions) or to a custodian designated by the Subscriber,
as applicable, and (ii) written notice from BRPM or the Transfer Agent evidencing the issuance to the Subscriber of the Subscribed
Shares, Incentive Shares and Incentive Warrants on and as of the Closing Date. In the event that the consummation of the Business
Combination does not occur within two (2) Business Days after the anticipated Closing Date specified in the Closing Notice, BRPM
shall promptly (but in no event later than two (2) Business Days after the anticipated Closing Date specified in the Closing Notice)
return the funds so delivered by the Subscriber to BRPM by wire transfer in immediately available funds to the account specified
by the Subscriber, and any book entries showing the Subscriber as the owner of the Subscribed Shares, Incentive Shares and Incentive
Warrants shall be deemed cancelled. For the purposes of this Subscription Agreement, “Business Day” means any
day other than a Saturday, Sunday or a day on which the Federal Reserve Bank of New York is closed.

Subscription Agreement has been duly executed and delivered by BRPM and, assuming the due authorization, execution and delivery
of the same by the Subscriber, is the valid and legally binding obligation of BRPM, enforceable against BRPM in accordance with

affecting creditors generally and by the availability of equitable remedies.


 


(d) The
execution and delivery of this Subscription Agreement, the issuance and sale of the Subscribed Shares, Incentive Shares and Incentive
Warrants and the compliance by BRPM with all of the provisions of this Subscription Agreement and the consummation of the transactions
contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute
a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets
of BRPM pursuant to the terms of (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or other agreement
or instrument to which BRPM is a party or by which BRPM is bound or to which any of the property or assets of BRPM is subject,
which would have a material adverse effect on the business, financial condition, stockholders’ equity or results of operations

(g) BRPM
has made available to the Subscriber (including via the SEC’s EDGAR system) a copy of each form, report, statement, schedule,
prospectus, proxy, registration statement and other document filed by BRPM with the SEC since the IPO. None of BRPM’s filings
with the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), contained, when filed
or, if amended, as of the date of such amendment with respect to those disclosures that are amended, any untrue statement of a
material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading.


 


(h) The
issued and outstanding shares of BRPM’s Common Stock (which prior to the closing of the Business Combination is named Class
A common stock and upon such closing will be renamed common stock) are registered pursuant to Section 12(b) of the Exchange Act
and are currently listed for trading on the NYSE under the symbol “BRPM.” Other than as has been disclosed by BRPM
in its filings with the SEC, there is no suit, action, proceeding or investigation pending or, to the knowledge of BRPM, threatened
against BRPM by the NYSE or the SEC with respect to any intention by such entity to deregister the shares of Common Stock or prohibit
or terminate the listing of the shares of Common Stock on the NYSE.


 


(i) BRPM
is not, and immediately after receipt of payment for the Subscribed Shares, Incentive Shares and Incentive Warrants will not be,

for the specific representations and warranties contained in this Section 5 and in any certificate or agreement delivered
pursuant hereto, none of BRPM, any person on behalf of BRPM, including without limitation any placement agent for the sale of the
Subscribed Shares, Incentive Shares and Incentive Warrants (a “Placement Agent”), or any of BRPM’s affiliates
(collectively, the “BRPM Parties”) has made, makes or shall be deemed to make any other express or implied representation
or warranty with respect to BRPM, this offering or the Business Combination, and the BRPM Parties disclaim any such representation
or warranty. Except for the specific representations and warranties expressly made by the Subscriber in Section 6 and in
any certificate or agreement delivered pursuant hereto, BRPM specifically disclaims that it, or anyone on its behalf, is relying
upon any other representations or warranties that may have been made by any Subscriber Party (as defined below).

(ii) has the requisite power and authority to enter into and perform its obligations under this Subscription Agreement.


 


(b) This
Subscription Agreement has been duly executed and delivered by the Subscriber, and assuming the due authorization, execution and
delivery of the same by BRPM, this Subscription Agreement shall constitute the valid and legally binding obligation of the Subscriber,
enforceable against the Subscriber in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency,
reorganization, moratorium and similar laws affecting creditors generally and by the availability of equitable remedies.


 


(c) The
execution and delivery of this Subscription Agreement, the purchase of the Subscribed Shares, Incentive Shares and Incentive Warrants
and the compliance by the Subscriber with all of the provisions of this Subscription Agreement and the consummation of the transactions
contemplated herein will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute
a default under, or result in the creation or imposition of any lien, charge or encumbrance upon any of the property or assets
of the Subscriber pursuant to the terms of, (i) any indenture, mortgage, deed of trust, loan agreement, lease, license or
other agreement or instrument to which the Subscriber is a party or by which the Subscriber is bound or to which any of the property
or assets of the Subscriber is subject; (ii) the organizational documents of the Subscriber; or (iii) any statute or
any judgment, order, rule or regulation of any court or governmental agency or body, domestic or foreign, having jurisdiction over
the Subscriber or any of its properties that, in the case of clauses (i) and (iii), would reasonably be expected to have a
material adverse effect on the Subscriber’s ability to consummate the transactions contemplated hereby, including the purchase
of the Subscribed Shares, Incentive Shares and Incentive Warrants (a “Subscriber Material Adverse Effect”).


 


(d) The
Subscriber (i) is an “accredited investor” (within the meaning of Rule 501(a) under the Securities Act) satisfying
the applicable requirements set forth on Schedule A, (ii) is acquiring the Subscribed Shares, Incentive Shares and Incentive
Warrants only for its own account and not for the account of others, or if the Subscriber is subscribing for the Subscribed Shares,
Incentive Shares and Incentive Warrants as a fiduciary or agent for one or more investor accounts, each owner of such account is
a qualified institutional buyer and the Subscriber has full investment discretion with respect to each such account, and the full
power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account,
and (iii) is not acquiring the Subscribed Shares, Incentive Shares and Incentive Warrants with a view to, or for offer or sale
in connection with, any distribution thereof in violation of the Securities Act (and has provided BRPM with the requested information
on Schedule A following the signature page hereto). The Subscriber is not an entity formed for the specific purpose of acquiring
the Subscribed Shares, Incentive Shares and Incentive Warrants.


 






    6


     


    

 


(e) The
Subscriber understands that the Subscribed Shares, Incentive Shares and Incentive Warrants are being offered in a transaction not
involving any public offering within the meaning of the Securities Act and that the Subscribed Shares, Incentive Shares and Incentive
Warrants have not been registered under the Securities Act. The Subscriber understands that the Subscribed Shares, Incentive Shares
and Incentive Warrants may not be resold, transferred, pledged or otherwise disposed of by the Subscriber absent an effective registration
statement under the Securities Act, except (i) to BRPM or a subsidiary thereof, or (ii) pursuant to an applicable exemption
from the registration requirements of the Securities Act, and, in each of cases (i) and (ii), in accordance with any applicable
securities laws of the states and other jurisdictions of the United States, and that any certificates or book-entry position representing
the Subscribed Shares, Incentive Shares and Incentive Warrants shall contain a legend to such effect. The Subscriber understands
that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the Subscribed
Shares, Incentive Shares and Incentive Warrants.


 


(f) The
Subscriber understands and agrees that the Subscriber is purchasing the Subscribed Shares, Incentive Shares and Incentive Warrants
directly from BRPM. The Subscriber further acknowledges that there have not been, and the Subscriber is not relying on, any representations,
warranties, covenants or agreements made to the Subscriber by BRPM, any other party to the Business Combination or any other person
or entity, expressly or by implication, other than those representations, warranties, covenants and agreements of BRPM included
in this Subscription Agreement. The Subscriber acknowledges that certain information provided by BRPM was based on projections,
and such projections were prepared based on assumptions and estimates that are inherently uncertain and are subject to a wide variety
of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially
from those contained in the projections.


 


(g) In
making its decision to purchase the Subscribed Shares, Incentive Shares and Incentive Warrants, the Subscriber has relied solely
upon independent investigation made by the Subscriber. Without limiting the generality of the foregoing, the Subscriber has not
relied on any statements or other information provided by BRPM (other than as set forth herein) or any Placement Agent concerning
BRPM, the Business Combination or the Subscribed Shares, Incentive Shares and Incentive Warrants. The Subscriber acknowledges and
agrees that the Subscriber has received such information as the Subscriber deems necessary in order to make an investment decision
with respect to the Subscribed Shares, Incentive Shares and Incentive Warrants, including with respect to BRPM, the Business Combination
and the Target. The Subscriber represents and agrees that the Subscriber and the Subscriber’s professional advisor(s), if
any, have had the full opportunity to ask such questions, receive such answers and obtain such information as the Subscriber and
the Subscriber’s professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the
Subscribed Shares, Incentive Shares and Incentive Warrants.


 






    7


     


    

 


(h) The
Subscriber became aware of this offering of the Subscribed Shares, Incentive Shares and Incentive Warrants solely by means of direct
contact between the Subscriber and BRPM or by means of contact from the Placement Agents, and the Subscribed Shares, Incentive
Shares and Incentive Warrants were offered to the Subscriber solely by direct contact between the Subscriber and BRPM or by contact
between the Subscriber and the Placement Agents. The Subscriber did not become aware of this offering of the Subscribed Shares,
Incentive Shares and Incentive Warrants, nor were the Subscribed Shares, Incentive Shares and Incentive Warrants offered to the
Subscriber, by any other means. The Subscriber acknowledges that BRPM represents and warrants that the Subscribed Shares, Incentive
Shares and Incentive Warrants (i) were not offered by any form of general solicitation or general advertising and (ii) are not
being offered in a manner involving a public offering under, or in a distribution in violation of, the Securities Act or any state
securities laws.


 


(i) The
Subscriber acknowledges that it is aware that there are substantial risks incident to the purchase and ownership of the Subscribed
Shares, Incentive Shares and Incentive Warrants. The Subscriber has such knowledge and experience in financial and business matters
as to be capable of evaluating the merits and risks of an investment in the Subscribed Shares, Incentive Shares and Incentive Warrants,
and the Subscriber has had an opportunity to seek, and has sought, such accounting, legal and tax advice as the Subscriber has
considered necessary to make an informed investment decision.


 


(j) The
Subscriber has adequately analyzed and fully considered the risks of an investment in the Subscribed Shares, Incentive Shares and
Incentive Warrants and determined that the Subscribed Shares, Incentive Shares and Incentive Warrants are a suitable investment
for the Subscriber and that the Subscriber is able at this time and in the foreseeable future to bear the economic risk of a total
loss of the Subscriber’s investment in BRPM. The Subscriber acknowledges specifically that a possibility of total loss exists.


 


(k) The
Subscriber understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the
Subscribed Shares, Incentive Shares and Incentive Warrants or made any findings or determination as to the fairness of this investment.


 


(l) The
Subscriber does not have, as of the date hereof, and during the 30-day period immediately prior to the date hereof the Subscriber
has not entered into, any “put equivalent position” as such term is defined in Rule 16a-1 under the Exchange Act or
short sale positions with respect to the securities of BRPM.


 


(m) The
Subscriber acknowledges and agrees that the book-entry position representing the Subscribed Shares, Incentive Shares and Incentive
Warrants (or each certificate representing such securities if subsequently requested and obtained by the Subscriber) will bear
or reflect, as applicable, a legend substantially similar to the following:


 






    8


     


    

 


“THIS
SECURITY WAS ORIGINALLY ISSUED IN A TRANSACTION EXEMPT FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES
ACT”), AND THIS SECURITY MAY NOT BE OFFERED, SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN
APPLICABLE EXEMPTION THEREFROM. THE HOLDER OF THIS SECURITY AGREES FOR THE BENEFIT OF THE COMPANY THAT (A) THIS SECURITY MAY BE
OFFERED, RESOLD, PLEDGED OR OTHERWISE TRANSFERRED, ONLY (I) PURSUANT TO ANY EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF
THE SECURITIES ACT, (II) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT, OR (III) TO THE COMPANY, IN
EACH OF CASES (I) THROUGH (III) IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAWS OF ANY STATE OF THE UNITED STATES,
AND (B) THE HOLDER WILL NOTIFY ANY SUBSEQUENT PURCHASER OF THIS SECURITY FROM IT OF THE RESALE RESTRICTIONS REFERRED TO IN
(A) ABOVE. THE COMPANY MAY REQUIRE THE DELIVERY OF A WRITTEN OPINION OF COUNSEL, CERTIFICATIONS AND/OR ANY OTHER INFORMATION
IT REASONABLY REQUIRES TO CONFIRM THE SECURITIES ACT EXEMPTION FOR SUCH TRANSACTION.”


 


(n) The
Subscriber’s acquisition and holding of the Subscribed Shares, Incentive Shares and Incentive Warrants will not constitute
or result in a non-exempt prohibited transaction under Section 406 of the Employee Retirement Income Security Act of 1974, as amended,
Section 4975 of the Internal Revenue Code of 1986, as amended (the “Code”), or any applicable similar law.


 


(o) If
the Subscriber is not a U.S. person as defined in Rule 902 under the Securities Act or a United States person as defined in the
Code, the Subscriber hereby represents that it has satisfied itself as to the full observance of the laws of its jurisdiction in
connection with any invitation to subscribe for the Subscribed Shares, Incentive Shares and Incentive Warrants or any use of this
Subscription Agreement, including (i) the legal requirements within its jurisdiction for the purchase of the Subscribed Shares,
Incentive Shares and Incentive Warrants, (ii) any foreign exchange restrictions applicable to such purchase, (iii) any governmental
or other consents that may need to be obtained, and (iv) the income tax and other tax consequences, if any, that may be relevant
to the purchase, holding, redemption, sale, or transfer of the Subscribed Shares, Incentive Shares and Incentive Warrants. The
Subscriber’s subscription and payment for and continued beneficial ownership of the Subscribed Shares, Incentive Shares and
Incentive Warrants will not violate any applicable securities or other laws of the Subscriber’s jurisdiction.


 


(p) The
Subscriber is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons administered by
the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) or in any Executive Order issued
by the President of the United States and administered by OFAC (“OFAC List”), or a person or entity prohibited
by any OFAC sanctions program, (ii) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R. Part 515,
or (iii) a non-U.S. shell bank or providing banking services indirectly to a non-U.S. shell bank (collectively, a “Prohibited
Investor”). The Subscriber agrees to provide law enforcement agencies, if requested thereby, such records as required
by applicable law, provided that the Subscriber is permitted to do so under applicable law. If the Subscriber is a financial institution
subject to the Bank Secrecy Act (31 U.S.C. Section 5311 et seq.) (the “BSA”), as amended by the USA PATRIOT
Act of 2001 (the “PATRIOT Act”), and its implementing regulations (collectively, the “BSA/PATRIOT Act”),
the Subscriber maintains policies and procedures reasonably designed to comply with applicable obligations under the BSA/PATRIOT
Act. To the extent required, the Subscriber maintains policies and procedures reasonably designed for the screening of its investors
against the OFAC sanctions programs, including the OFAC List. The Subscriber also represents that, to the extent required, the
Subscriber maintains policies and procedures reasonably designed to ensure that the funds held by the Subscriber and used to purchase
the Subscribed Shares, Incentive Shares and Incentive Warrants were legally derived.


 






    9


     


    

 


(q) The
Subscriber acknowledges that in connection with the offer and sale of the Subscribed Shares, Incentive Shares and Incentive Warrants,
(i) no disclosure or offering document has been delivered to the Subscriber by any Placement Agent or any of their respective affiliates
and (ii) no Placement Agent has acted as the Subscriber’s financial advisor or fiduciary.


 


(r) Except
for the specific representations and warranties contained in this Section 6 and in any certificate or agreement delivered
pursuant hereto, none of the Subscriber nor any person acting on behalf of the Subscriber nor any of the Subscriber’s affiliates
(the “Subscriber Parties”) has made, makes or shall be deemed to make any other express or implied representation
or warranty with respect to the Subscriber and this offering, and the Subscriber Parties disclaim any such representation or warranty.
Except for the specific representations and warranties expressly made by BRPM in Section 5 of this Agreement and in any
certificate or agreement delivered pursuant hereto, the Subscriber specifically disclaims that it, or anyone on its behalf, is
relying upon any representations or warranties that may have been made by BRPM or any person acting on behalf of BRPM or any of
BRPM’s affiliates.


 


7. Registration
Rights. BRPM agrees that, within fifteen (15) business days after the consummation of the Business Combination, BRPM will file
with the SEC (at BRPM’s sole cost and expense) a registration statement (the “Registration Statement”)
registering the resale of the Subscribed Shares, Incentive Shares and Incentive Warrants (and shares of Common Stock underlying
the Incentive Warrants) (collectively, the “Covered Securities”) issued to the Subscriber, and BRPM shall use
its commercially reasonable efforts to have the Registration Statement declared effective as soon as practicable after the filing
thereof. BRPM agrees that it will cause such registration statement or another shelf registration statement to remain effective
until the earlier of (i) two years from the issuance of the Subscribed Shares, Incentive Shares and Incentive Warrants and (ii)
the first date on which the Subscriber can sell all of the Covered Securities (or shares received in exchange therefor) under Rule
144 of the Securities Act within 90 days without limitation as to the amount of such securities that may be sold. BRPM may delay
filing or suspend the use of any such registration statement if BRPM delivers to the holders of the Subscribed Shares a certificate
signed by an officer of BRPM certifying that, in the good faith judgment of the board of directors of BRPM, such registration and
the offering pursuant thereto would reasonably be expected to materially adversely affect or materially interfere with any bona
fide material financing or transaction of BRPM or would require disclosure of information that has not been disclosed to the public,
the premature disclosure of which would materially adversely affect BRPM. Such certificate shall contain a statement of the reasons
for such postponement and an approximation of the anticipated delay. The holders receiving such certificate shall keep the information
contained in such certificate confidential. BRPM’s obligations to include the Covered Securities (or shares issued in exchange
therefor) in the Registration Statement are contingent upon the Subscriber’s timely furnishing in writing to BRPM such information
regarding the Subscriber, the securities of BRPM held by the Subscriber and the intended method of disposition of the Covered Securities
as shall be reasonably requested by BRPM to effect the registration of the Covered Securities, and shall execute such documents
in connection with such registration as BRPM may reasonably request that are customary of a selling stockholder in similar situations.


 






    10


     


    

 


8. Termination.
This Subscription Agreement shall terminate and be void and of no further force and effect, and all rights and obligations of the
parties hereunder shall terminate without any further liability on the part of any party in respect thereof, upon the earlier to
occur of (a) such date and time as the Business Combination Agreement is terminated in accordance with its terms and (b) upon the
mutual written agreement of each of the parties hereto to terminate this Subscription Agreement; provided that nothing herein
will relieve any party from liability for any willful breach hereof prior to the time of termination, and each party will be entitled
to any remedies at law or in equity to recover losses, liabilities or damages arising from any such breach. BRPM shall promptly
notify the Subscriber of any termination of the Business Combination Agreement promptly after the termination thereof.


 


9. Additional

equity or any other theory of legal liability (any and all such claims are collectively referred to hereafter as the “Released
Claims”), (ii) irrevocably waives any Released Claims that it may have against the Trust Account now or in the future
as a result of, or arising out of, any negotiations, contracts or agreements with BRPM, and (iii) will not seek recourse against

of incorporation in respect of Common Stock of BRPM acquired by any means other than pursuant to this Subscription Agreement.

Subscriber hereby agrees that neither it, nor any person or entity acting on its behalf or pursuant to any understanding with it,
