receipt of a Tag Along Notice hereunder, the QIA Related Parties, in their sole discretion, will have ten (10) business days to exercise,
by delivery of written notice to the Initiating Stockholders (the “Tag Election”), the right to sell to the Prospective
Purchaser a number of shares of Class A Common Stock up to the product of the total number of Class A Common Stock held by the
QIA Related Parties multiplied by the Tag Percentage set forth in the Tag Along Notice (for clarity, in such a joint sale by the
AES Related Parties and the Siemens Related Parties where the number of the Subject Securities being included in such sale by one party
is different from that of the other party, the QIA Related Parties may use the greater of the two individual Tag Percentages in calculating
the number of its pro rata portion of the applicable Subject Securities) (any of the QIA Related Parties exercising such right,
a “Tagging Stockholder” and any such shares of Class A Common Stock designated for sale by a Tagging Stockholder,
collectively, the “Tag Along Securities”). For purposes of this Section 4(d), Subject Securities will be
counted as follows: (A) each share of Class A Common Stock will be counted as one (1) Subject Security and (B) each
share of Class B Common Stock and Common Unit together will be counted as one (1) Subject Security. Any such exercise of the
Tag Along Rights by a Tagging Stockholder shall be irrevocable. If the QIA Related Parties have not delivered a Tag Election within such
ten (10) business day period, the Initiating Stockholders shall have the right to freely Transfer to the Prospective Purchaser all,
but not less than all, of the Subject Securities proposed to be sold as set forth in the Tag Along Notice for a period not to exceed one
hundred and eighty (180) days following the end of such ten (10) day period, subject to extension to allow pending applicable governmental
consents and approvals; provided, that such Transfer is otherwise on the same or substantially similar or less preferable (to the
Initiating Stockholders) terms and conditions as those set forth in the Tag Along Notice. If, at the end of such one hundred and eighty
(180) day period (as extended to permit pending governmental consents and approvals), the Initiating Stockholders have not completed the
Tag Along Transfer in accordance with the terms and conditions of the Tag Along Notice, all the restrictions on a Transfer contained in
this Section 4(d) with respect to the Subject Securities owned by the Initiating Stockholders shall again be in effect;
and


 


(vii)         The
Tag Along Securities will be included in the relevant Transfer on the same terms and subject to the same conditions set forth in the Tag
Along Notice and applicable to the Subject Securities that the Initiating Stockholders are selling (except that governmental consents
and approvals shall be obtained by each Tagging Stockholder as required under applicable law, even if different from those required from
the Initiating Stockholders in connection with the Tag Along Transfer). Each Tagging Stockholder agrees that it will take such actions
and execute such other agreements as the Initiating Stockholders may reasonably request in connection with the consummation of the Tag
Along Transfer and the transactions contemplated thereby, including any purchase agreement, proxies, custody agreements, powers of attorney,
written consents in lieu of meetings or waiver of appraisal rights.

(e)             Drag-Along
Rights.


 


(i)          Notwithstanding
the provisions of Section 4(d) above, in the event that AES and Siemens collectively Transfer (as defined in the LLC
Agreement) to a Third Party one hundred percent (100%) of their respective Subject Securities (a “Drag-Along Transaction”)
and (A) as a result of such Drag-Along Transaction, such Third Party acquires at least sixty percent (60%) (in the aggregate) of
the issued and outstanding shares of Class A Common Stock (including for these purposes the Underlying Class A Shares) and (B) the
purchase price set forth in the bona fide offer from the Third Party purchaser represents at least a thirty percent (30%) increase on
the 30-day average trading price for the shares of Class A Common Stock (a “Drag Offer”), then AES and Siemens
may, at their option, require the QIA Related Parties to sell one hundred percent (100%) of their shares of Class A Common Stock
to the third party by giving written notice (the “Drag Notice”) to the QIA Related Parties not less than thirty (30)
days prior to the date stated in the Drag Offer for consummation of the sale contemplated by the Drag Offer (the “Approved Sale”).
The Drag Notice shall contain written notice of the exercise of AES and Siemens’ rights pursuant to this Section 4(e),
and shall set forth the consideration to be paid by the third party and the other material terms and conditions of the Drag Offer.


 


(ii)          The
purchase of shares of Class A Common Stock from the QIA Related Parties pursuant to this Section 4(e) shall be on
substantially the same terms and conditions and for the same type of consideration payable to AES and Siemens.


 


(iii)          If
AES and Siemens exercise their rights pursuant to this Section 4(e), the QIA Related Parties shall sell, exchange or otherwise
dispose to such Third Party one hundred percent (100%) of their shares of Class A Common Stock.


 


(iv)          In
connection with the consummation of any Approved Sale, QIA acknowledges and agrees that it shall:


 


		a.	consent to and raise no objections against any such Approved Sale; and



 


		b.	not exercise any rights of appraisal, dissenters’ rights or similar rights, all of which are hereby waived.

    11 


     


    

 


(b)          The
AES Related Parties, the Siemens Related Parties and the QIA Related Parties shall comply with the requirements of the Charter and Bylaws
when designating and nominating individuals as Directors, in each case, to the extent such requirements are applicable to Directors generally.
Notwithstanding anything to the contrary set forth herein, in the event that the Board determines, within sixty (60) days after compliance
with the first sentence of this Section 5(b), in good faith, after consultation with outside legal counsel, that its nomination,
appointment or election of a particular Director designated for nomination in accordance with Section 1 or Section 2,
as applicable, would constitute a breach of its fiduciary duties or does not otherwise comply with any requirements of the Charter or
Bylaws, then the Board shall inform the AES Related Parties, Siemens Related Parties and/or the QIA Related Parties, as applicable, of
such determination in writing and explain in reasonable detail the basis for such determination and shall, to the fullest extent permitted
by law, nominate, appoint or elect another individual designated for nomination, election or appointment to the Board by the AES Related
Parties, Siemens Related Parties and/or the QIA Related Parties, as applicable (subject in each case to this Section 5(b)).
The Board and the Corporation shall, to the fullest extent permitted by law, take all Necessary Action required by this Section 5
with respect to the election of such substitute designees to the Board.


 


(c)          In
addition to any voting requirements contained in this Agreement or the organizational documents of the Corporation or any of its Subsidiaries,
the Corporation shall not, directly or indirectly, enter into or conduct business or operations or hold or acquire assets in its own name
or otherwise other than through Fluence LLC and its Subsidiaries without the prior written approval of (i) AES for as long as the
AES Related Parties Beneficially Own, directly or indirectly any of the issued and outstanding Common Units and (ii) Siemens for
as long as the Siemens Related Parties Beneficially Own, directly or indirectly any of the issued and outstanding Common Units; provided,
however, that nothing in this clause (c) shall be deemed to prohibit the Corporation from, and no consent of AES, Siemens or any
other Person shall be required for the Corporation to engage in, (i) holding or using cash received by the Corporation as a result
of the Corporation’s investment in Fluence LLC or (ii) re-investing cash into Fluence LLC (whether by way of intercompany loan,
investment or otherwise).


 


(d)          Upon
the request of either the AES Related Parties or the Siemens Related Parties that wish to (x) pledge, hypothecate or grant security
interests in any or all of the shares of Common Stock held by it including to banks or financial institutions as collateral or security
for loans, advances or extensions of credit or (y) transfer all (but not less than all) of the shares of Common Stock and/or Common
Units held by it, including to a third party transferee, in a transfer not prohibited by the LLC Agreement, each of the Corporation and
Fluence LLC agrees to cooperate with the AES Related Parties or the Siemens Related Parties, as the case may be, in taking any action
reasonably necessary to consummate any such pledge, hypothecation, grant or transfer, including without limitation, delivery of letter
agreements to lenders in form and substance reasonably satisfactory to such lenders (which may include agreements by the Corporation and
Fluence LLC in respect of the exercise of remedies by such lenders), instructing the transfer agent to transfer any such shares of Common
Stock subject to the pledge, hypothecation or grant into the facilities of The Depository Trust Company without restricted legends and
cooperating in diligence or other matters as may reasonably requested by either AES Related Parties or the Siemens Related Parties in
connection therewith.


 






    12 


     


    

 


(e)          In
the event that the Corporation effects the separation of any portion of its business into one or more entities (each, a “NewCo”),
whether existing or newly formed, including without limitation by way of spin-off, split-off, carve-out, demerger, recapitalization, reorganization
or similar transaction, and any Stockholder will receive equity interests in any such NewCo as part of such separation, the Corporation
shall cause any such NewCo to enter into a Stockholders agreement with the Stockholders that provides AES, Siemens and QIA with rights
vis-á-vis such NewCo that are substantially identical to those set forth in this Agreement.

QIA Related Parties beneficially own, directly or indirectly, in the aggregate less than five percent (5%) of all issued and outstanding
shares of Class A Common Stock (including for this purpose the Underlying Class A Shares) or (ii) following a Transfer
to a Third Party by the AES Related Parties or the Siemens Related Parties of its shares of Class A Common Stock and/or Common Units
(in the case of Common Units, together with the applicable shares of Class B Stock) and the associated right to designate for nomination
one or more Directors, the QIA Related Parties determine that they would not be able to vote (or cause to be voted) for any director candidate
nominated by such Third Party.

terminates in accordance with this Section 6.

herein, all of the terms and provisions of this Agreement shall be binding upon, shall inure to the benefit of and shall be enforceable
by the respective successors and permitted assigns of the parties hereto. This Agreement may not be assigned (by operation of law or otherwise)
without the express prior written consent of the other parties hereto, and any attempted assignment, without such consents, will be null
and void; provided, however, that each of AES, Siemens and QIA is permitted to assign this Agreement to their respective

party to, and be bound by all of the provisions of this Agreement as a “Stockholder” and an “AES Related Party,”

of any of the parties to comply with any obligation, covenant, agreement or condition herein may be waived by the party or parties entitled
to the benefits thereof only by a written instrument signed by the party or parties granting such waiver, but such waiver or failure to
insist upon strict compliance with such obligation, covenant, agreement or condition shall not operate as a waiver of, or estoppel with
respect to, any subsequent or other failure.

No failure on the part of
either party hereto to exercise any power, right, privilege or remedy under this Agreement, and no delay on the part of either party hereto
