Last Updated: July 25, 2024.

THIS AGREEMENT GOVERNS YOUR ACQUISITION AND USE OF C4 ENERGY
STORAGE’S SERVICE. BY CLICKING “I ACCEPT THE TERMS OF SERVICE,” YOU AGREE
TO THESE TERMS OF SERVICE (THESE “TERMS“). IF YOU ARE ENTERING INTO THESE
TERMS ON BEHALF OF A COMPANY OR OTHER LEGAL ENTITY, THEN YOU REPRESENT
THAT YOU HAVE THE AUTHORITY TO BIND THAT COMPANY OR OTHER LEGAL ENTITY.

1. SCOPE OF AGREEMENT. These Terms govern C4 Energy Storage LLC’s (“C4 Energy
Storage“) provision of services to you (“Services“). The scope of Services includes user input
based calculations producing an estimate accessible through https://app.energystoragesize.com
(the “Site“). To use the Services, you will have to request a subscription through the Site
(“Subscription“). C4 Energy Storage has the right to reject your application for a Subscription in
its sole discretion.

2. PROPRIETARY RIGHTS
(a) License to Services. Subject to the terms and conditions of these Terms, C4 Energy
Storage grants you a non-exclusive, non-transferable, non-sublicensable, limited license to
access and use the Services you select on the Site.
(b) Restrictions on Use of Services. The Services are licensed for internal use only. In
connection with your use of the Services, you will comply with all applicable laws, rules and
regulations. You will not, and will not permit any third party to: (i) copy, modify, translate, or
create derivative works of the Services; (ii) reverse engineer, decompile, disassemble or
otherwise attempt to reconstruct, identify or discover any source code, underlying ideas,
underlying user interface techniques, or algorithms of the Services; (iii) lend, lease, offer for
sale, sell or otherwise use the Services for the benefit of third parties; or (iv) attempt to
circumvent any license, timing or use restrictions that are built into the Services. The Services
are subject to usage limits, including, for example, the limits on users specified on the Site.
Unless otherwise specified, (A) the Services may not be accessed by more than the number of
users associated with your Subscription tier, (B) a user’s password may not be shared with any
other individual, and (C) a user identification may be reassigned to a new individual replacing
one who no longer requires ongoing use of the Services. If you exceed a contractual usage
limit, C4 Energy Storage may work with you to seek to reduce your usage so that it conforms to
that limit. If, notwithstanding our efforts, you are unable or unwilling to abide by a contractual
usage limit, you will be required to upgrade your Subscription for additional quantities of the
applicable Services promptly upon our request, and/or pay any applicable Fees for excess
usage.
(c) C4 Energy Storage Ownership of Services. Except for the limited rights granted in
Section 2(a) above, C4 Energy Storage retains all rights, titles, and interests, including all
intellectual property rights, in and to the Services. You acknowledge that the Services include
C4 Energy Storage’s valuable trade secrets and improper use or disclosure would cause C4
Energy Storage irreparable harm. Accordingly, you agree to use the Services solely as
authorized in these Terms. You further acknowledge that the license granted pursuant to these
Terms is not a sale and does not transfer to you title or ownership of the Services or a copy of
the Services, but only a right of limited use. ALL RIGHTS NOT EXPRESSLY GRANTED HERE
UNDER ARE RESERVED TO C4 ENERGY STORAGE.
(c) Licensee Data and Content. Subject to the terms and conditions of these Terms, you
grant C4 Energy Storage a limited, non-transferable (except pursuant to Section 16(a) below)
license to use the information and data entered into the Services by you and/or your personnel,
or by any third parties acting on behalf of you or at your request (“Content“) for the purpose of
providing the Services. You represent and warrant that: (i) you own the Content posted by you
on or through the Services or otherwise have the right to grant the license set forth in this
Section 2(d); (ii) the posting and use of Content on or through the Services does not violate the
privacy rights, publicity rights, copyrights, contract rights, intellectual property rights, or any
other rights of any person; and (iii) the posting of Content on the Services does not result in a
breach of contract between you and any third party. C4 Energy Storage may use Content in an
aggregated and/or anonymized manner for purposes of sales, marketing, business
development, product enhancement, customer service, or as otherwise detailed in our Privacy
Policy.

3. USE OF THE SERVICES. You will (i) be responsible for your (and as applicable, your
personnel’s) compliance with these Terms, (ii) use commercially reasonable efforts to prevent

substitute for tax, business, or other professional advice. While we have made every attempt to
ensure that the information contained on the Services has been obtained from reliable sources,
C4 Energy Storage is not responsible for any errors or omissions, or for the Results. All
information on the Site and in the Services is provided “as is,” with no guarantee of

Feedback or any derivative thereof in any manner or media now known or hereafter devised
without any remuneration, compensation or credit to you.

10. CONFIDENTIAL INFORMATION
(a) Definition of Confidential Information. As used herein, “Confidential Information”
means all confidential information disclosed by a party (“Disclosing Party“) to the other party
(“Receiving Party“), whether orally or in writing, that is designated as confidential or that

reasonably should be understood to be confidential given the nature of the information and the
circumstances of disclosure. Your Confidential Information includes Content; our Confidential
Information includes the Services; and Confidential Information of each party includes business
and marketing plans, technology and technical information, product plans and designs, and
business processes disclosed by such party. However, Confidential Information (other than
Content) will not include any information that (i) is or becomes generally known to the public
without breach of any obligation owed to the Disclosing Party, (ii) was known to the Receiving
Party prior to its disclosure by the Disclosing Party without breach of any obligation owed to the
Disclosing Party, (iii) is received from a third party without breach of any obligation owed to the
Disclosing Party, or (iv) was independently developed by the Receiving Party.
(b) Protection of Confidential Information. The Receiving Party will use the same degree
of care that it uses to protect the confidentiality of its own confidential information of like kind
(but in no event less than reasonable care). The Receiving Party agrees (i) not to use any
Confidential Information of the Disclosing Party for any purpose outside the scope of these
Terms, and (ii) except as otherwise authorized by the Disclosing Party in writing, to limit access
to Confidential Information of the Disclosing Party to those of its and its affiliates’ employees,
contractors and agents who need such access for purposes consistent with these Terms and
who have signed confidentiality agreements with the Receiving Party containing protections no
less stringent than those herein.
(c) Compelled Disclosure. The Receiving Party may disclose Confidential Information of the
Disclosing Party if it is compelled by law to do so, provided the Receiving Party gives the
Disclosing Party prior notice of such compelled disclosure (to the extent legally permitted) and
reasonable assistance, at the Disclosing Party’s cost, if the Disclosing Party wishes to contest
the disclosure. If the Receiving Party is compelled by law to disclose the Disclosing Party’s
Confidential Information as part of a civil proceeding to which the Disclosing Party is a party,
and the Disclosing Party is not contesting the disclosure, the Disclosing Party will reimburse the
Receiving Party for its reasonable cost of compiling and providing secure access to such
Confidential Information.

11. TERM AND TERMINATION
(a) Term of Subscriptions. The term of each Subscription is one month (the “Term“), unless

other party that: (a) it is duly organized, validly existing and in good standing as a corporation or
other entity as represented herein under the laws and regulations of its jurisdiction of
incorporation, organization or chartering; (b) it has the right, power and authority to enter these
Terms and to grant the rights and licenses granted hereunder and to perform all of its
obligations hereunder; (c) the execution of these Terms by its representative whose signature is
set forth at the end hereof has been duly authorized by all necessary corporate or organizational
action of the party; (d) when executed and delivered by both parties, these Terms will constitute
