Exhibit 10.8


 


UNIT PURCHASE AGREEMENT


BETWEEN


THE REGISTRANT AND ENERGY CLOUD SPONSOR HOLDINGS
LIMITED


 


_______________, 2021


 


Gentlemen:


 


Energy Cloud I Acquisition Corporation ( “Company”),
a blank check company formed for the purpose of acquiring one or more businesses or entities (a “Business Combination”), intends
to register its securities under the Securities Act of 1933, as amended (“Securities Act”), in connection with its initial
public offering (“IPO”). The Company currently anticipates selling units in the IPO, each comprised of one ordinary share,
no par value per share of the Company (“Ordinary Shares”), one half of one right (“Rights”), each whole right
entitling holder to receive one tenth (1/10) of one Ordinary Share, and one warrant (“Warrant”), each whole Warrant entitling
holder to purchase one Ordinary Share.


 


The undersigned hereby commits to purchase an aggregate
of 232,500 units of the Company (“Initial Units”) at $10.00 per Initial Unit for an aggregate purchase price of $2,325,000
(the “Initial Purchase Price”). Additionally, if the underwriters in the IPO exercise their over-allotment option in full
or part, the undersigned further commits to purchase up to an additional 16,875 Units (“Additional Units” and together with
the Initial Units, the “Private Units”) at $10.00 per Additional Unit for an aggregate purchase price of up to $168,750 (the
“Over-Allotment Purchase Price” and together with the Initial Purchase Price, the “Purchase Price”). The Private
Units will be identical to the units to be sold in the IPO except as to be described in the Company’s registration statement filed
in connection with the IPO (“Registration Statement”). At least 24 hours prior to the effective date (“Effective Date”)
of the Registration Statement, the undersigned will cause the Purchase Price to be delivered to RAITI, PLLC, counsel for the Company (“Counsel”),
by wire transfer as set forth in the instructions attached as Exhibit A hereto to hold in a non-interest bearing account until the Company
consummates the IPO. The undersigned agrees that if the size of the IPO is increased or decreased for any reason, the amount of the undersigned’s
investment will be either increased or decreased, as applicable, so that the undersigned’s percentage of the aggregate investment
in Private Units (collectively, the “Private Securities”) made by the undersigned and other investors of the Company remains
the same. If the size of the offering is increased, the undersigned agrees that it will deliver the purchase price for such additional
Private Securities to Counsel as set forth above or as promptly as is reasonably practicable following the increase if it is on the Effective
Date. If the size of the offering is decreased, the unused portion of the Purchase Price shall be returned to the undersigned.


 


The consummation of the purchase and issuance of
the Initial Units and Additional Units (if any) shall occur simultaneously with the consummation of the IPO and over-allotment option,
respectively. Simultaneously with the consummation of the IPO, Counsel shall deposit the Initial Purchase Price, without interest or deduction,
into the trust fund (“Trust Fund”) established by the Company for the benefit of the Company’s public shareholders as
described in the Registration Statement. Simultaneously with the consummation of all or any part of the over-allotment option, Counsel
shall deposit the pro-rata portion of the Over-Allotment Purchase Price, based upon the amount of the over-allotment option that has been
exercised, without interest or deduction, into the Trust Fund. Upon expiration of the over-allotment option, Counsel shall return any
unused portion of the Over-Allotment Purchase Price to the undersigned. If the Company does not complete the IPO within thirty (30) days
from the Effective Date, the Purchase Price (without interest or deduction) will be returned to the undersigned.


 


Each of the Company and the undersigned acknowledges
and agrees that Counsel is serving hereunder solely as a convenience to the parties to facilitate the purchase of the Private Securities
and Counsel’s sole obligation under this letter agreement is to act with respect to holding and disbursing the Purchase Price for
the Private Securities as described above. Counsel shall not be liable to the Company or the undersigned or any other person or entity
in respect of any act or failure to act hereunder or otherwise in connection with performing its services hereunder unless Counsel has
acted in a manner constituting gross negligence or willful misconduct. The Company shall indemnify Counsel against any claim made against
it (including reasonable attorney’s fees) by reason of it acting or failing to act in connection with this letter agreement except
as a result of its gross negligence or willful misconduct. Counsel may rely and shall be protected in acting or refraining from acting
upon any written notice, instruction or request furnished to it hereunder and believed by it to be genuine and to have been signed or
presented by the proper party or parties.

	 	●	the Private Securities and the underlying securities will include any additional terms or restrictions as is customary in other similarly structured blank check company offerings or as may be reasonably required by the underwriters in the IPO in order to consummate the IPO, each of which will be set forth in the Registration Statement.

execute agreements in form and substance typical for transactions of this nature necessary to effectuate the foregoing agreements and
