Climate Change Crisis Real Impact I Acquisition Corporation
300 Carnegie Center, Suite 150,
Princeton, NJ 08540

Re:          Initial Public Offering

Ladies and Gentlemen:

This letter (this “Letter Agreement”) is being delivered to you in accordance
with the Underwriting Agreement (the “Underwriting Agreement”) to be entered
into by and among Climate Change Crisis Real Impact I Acquisition Corporation, a
Delaware corporation (the “Company”), and Citigroup Global Markets Inc., BofA
Securities, Inc. and Barclays Capital Inc., as representatives (the
“Representatives”) of the several underwriters (each, an “Underwriter” and
collectively, the “Underwriters”), relating to an underwritten initial public
offering (the “Public Offering”), of 23,000,000 of the Company’s units
(including up to 3,000,000 units that may be purchased by the Underwriters to
cover over-allotments, if any) (the “Units”), each comprising one share of the
Company’s Class A common stock, par value $0.0001 per share (the “Common
Stock”), and one-half of one redeemable warrant.  Each whole warrant (each, a
“Warrant”) entitles the holder thereof to purchase one share of Common Stock at
a price of $11.50 per share, subject to adjustment.  The Units will be sold in
the Public Offering pursuant to a registration statement on Form S-1 and a
prospectus (the “Prospectus”), filed by the Company with the U.S. Securities and
Exchange Commission (the “Commission”) and the Company has applied to have the
Units listed on the New York Stock Exchange.  Certain capitalized terms used
herein are defined in paragraph 13 hereof.

In order to induce the Company and the Underwriters to enter into the
Underwriting Agreement and to proceed with the Public Offering, to induce the
PIMCO Investors and Climate Change Crisis Real Impact I Sponsor, LLC, a Delaware
limited liability company (the “CRIS Consortium”), to invest in Climate Change
Crisis Real Impact I Acquisition Holdings, LLC, a Delaware limited liability
company (the “Sponsor”), and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, each of the Sponsor,
OC III LVS IX LP, a Delaware limited partner (“COF 3”), TOCU XXXVII LLC, a
Delaware limited liability company (together with COF 3, the “PIMCO Investors”),
the CRIS Consortium (together with the PIMCO Investors, the “Investors”) and the
undersigned individuals, each of whom is a member of the Company’s board of
directors and/or management team or is a consultant for the Company (each, an
“Insider” and collectively, the “Insiders”), hereby agrees with the Company as
follows:

1.
It is acknowledged and agreed that the Company shall not enter into a definitive
agreement regarding a proposed Business Combination without the prior consent of
the Sponsor and the PIMCO Investors.

2.
The Sponsor and each Insider hereby agrees that in the event that the Company
fails to consummate a Business Combination within 24 months from the closing of
the Public Offering, or such later period approved by the Company’s stockholders
in accordance with the Company’s amended and restated certificate of
incorporation (the “Charter”), the Sponsor and each Insider shall take all
reasonable steps to cause the Company to (i) cease all operations except for the
purpose of winding up, (ii) as promptly as reasonably possible but not more than
10 business days thereafter, subject to lawfully available funds therefor,
redeem 100% of the Common Stock sold as part of the Units in the Public Offering
(the “Offering Shares”), at a per-share price, payable in cash, equal to the
aggregate amount then on deposit in the Trust Account (as defined below),
including interest earned on the funds held in the Trust Account and not
previously released to the Company to pay its franchise and income taxes (less
up to $100,000 of interest to pay dissolution expenses), divided by the number
of then outstanding Offering Shares, which redemption will completely extinguish
all Public Stockholders’ rights as stockholders (including the right to receive
further liquidation distributions, if any), subject to applicable law, and (iii)
as promptly as reasonably possible following such redemption, subject to the
approval of the Company’s remaining stockholders and the Company’s board of
directors, dissolve and liquidate, subject in each case to the Company’s
obligations under Delaware law to provide for claims of creditors and other
requirements of applicable law.  The Sponsor and each Insider agrees not to
propose any amendment to the Charter to (a) modify the substance or timing of
the Company’s obligation to allow redemption in connection with a Business
Combination or to redeem 100% of the Offering Shares if the Company does not
complete a Business Combination within the time period set forth in the Charter
or (b) with respect to any other provision relating to stockholders’ rights or
pre-initial Business Combination activity, unless the Company provides Public
Stockholders with the opportunity to redeem their shares of Common Stock upon
approval of any such amendment at a per-share price, payable in cash, equal to
the aggregate amount then on deposit in the Trust Account, including interest
earned on the funds held in the Trust Account and not previously released to the
Company to pay its franchise and income taxes (less up to $100,000 of interest
to pay dissolution expenses), divided by the number of then outstanding Offering
Shares.

--------------------------------------------------------------------------------

The Sponsor and each Insider acknowledges that it, he or she has no right,
title, interest or claim of any kind in or to any monies held in the Trust
Account or any other asset of the Company as a result of any liquidation of the
Company with respect to the Founder Shares held by it, him or her. The Sponsor
and each Insider hereby agrees that if the Company seeks stockholder approval of
a proposed Business Combination, then in connection with such proposed Business
Combination, it, he or she shall vote any shares of Capital Stock owned by it,
him or her in favor of any proposed Business Combination.  The Sponsor and each
Insider hereby waives, with respect to any shares of Common Stock held by it,
him or her, if any, any redemption rights it, he or she may have in connection
with the consummation of a Business Combination, including, without limitation,
any such rights available in the context of (i) a stockholder vote to approve
such Business Combination, or (ii) a stockholder vote to approve an amendment to
the Charter to (a) modify the substance or timing of the Company’s obligation to
allow redemption in connection with a Business Combination or to redeem 100% of
the Offering Shares if the Company does not complete a Business Combination
within the time period set forth in the Charter or (b) with respect to any other
provision relating to stockholders’ rights or pre-initial Business Combination
activity (although the Sponsor and the Insiders shall be entitled to liquidation
rights with respect to any Offering Shares it or they hold if the Company fails
to consummate a Business Combination within the time period set forth in the
Charter). If the Company engages in a tender offer in connection with any
proposed Business Combination, the Sponsor and each Insider agrees that it, he
or she will not seek to sell its, his or her shares of Common Stock to the
Company in connection with such tender offer.

3.
The undersigned acknowledges and agrees that prior to entering into a definitive
agreement for a Business Combination with a target business that is affiliated
with the undersigned or any other Insiders of the Company or their affiliates,
such transaction must be approved by a majority of the Company’s disinterested
independent directors and the Company must obtain an opinion from an independent
investment banking firm or an independent accounting firm that such Business
Combination is fair to the Company from a financial point of view.

4.
During the period commencing on the effective date of the Underwriting Agreement
and ending 180 days after such date, the Sponsor and each Insider shall not,
without the prior written consent of the Representatives, (i) sell, offer to
sell, contract or agree to sell, hypothecate, pledge, grant any option to
purchase or otherwise dispose of or agree to dispose of, directly or indirectly,
or establish or increase a put equivalent position or liquidate or decrease a
call equivalent position within the meaning of Section 16 of the Securities
Exchange Act of 1934, as amended (the “Exchange Act”), and the rules and
regulations of the Commission promulgated thereunder, with respect to any Units,
shares of Common Stock, Founder Shares, Warrants or any securities convertible
into, or exercisable, or exchangeable for, shares of Common Stock (but excluding
Units and shares of Common Stock purchased in the Public Offering or thereafter)
owned by it, him or her, (ii) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of any Units, shares of Common Stock, Founder Shares, Warrants or any
securities convertible into, or exercisable, or exchangeable for, shares of
Common Stock owned by it, him or her, whether any such transaction is to be
settled by delivery of such securities, in cash or otherwise, or (iii) publicly
announce any intention to effect any transaction specified in clause (i) or
(ii). The provisions of this paragraph will not apply if the release or waiver
is effected solely to permit a transfer not for consideration and the transferee
has agreed in writing to be bound by the same terms described in this Letter
Agreement to the extent and for the duration that such terms remain in effect at
the time of the transfer.

2

--------------------------------------------------------------------------------

5.
In the event of the liquidation of the Trust Account upon the failure of the
Company to consummate its initial Business Combination within the time period
set forth in the Charter, the Sponsor (the “Indemnitor”), which for purposes of
clarification shall not extend to any other shareholders, members or managers of
the Sponsor, or any of the other undersigned, agrees to indemnify and hold
harmless the Company against any and all loss, liability, claim, damage and
expense whatsoever (including, but not limited to, any and all legal or other
expenses reasonably incurred in investigating, preparing or defending against
any litigation, whether pending or threatened) to which the Company may become
subject as a result of any claim by (i) any third party for services rendered or
products sold to the Company or (ii) any prospective target business with which
the Company has entered into a written letter of intent, confidentiality or
other similar agreement or Business Combination agreement (a “Target”);
provided, however, that such indemnification of the Company by the Indemnitor
shall (x) apply only to the extent necessary to ensure that such claims by a
third party for services rendered (other than the Company’s independent public
accountants) or products sold to the Company or a Target do not reduce the
amount of funds in the Trust Account to below the lesser of (i) $10.00 per
Offering Share and (ii) the actual amount per Offering Share held in the Trust
Account as of the date of the liquidation of the Trust Account, if less than
$10.00 per Offering Share is then held in the Trust Account due to reductions in
the value of the trust assets, less interest earned on the funds in the Trust
Account which may be withdrawn to pay franchise and income taxes, (y) not apply
to any claims by a third party or a Target which executed a waiver of any and
all rights to the monies held in the Trust Account (whether or not such waiver
is enforceable) and (z)  not apply to any claims under the Company’s indemnity
of the Underwriters against certain liabilities, including liabilities under the
Securities Act of 1933, as amended (the “Securities Act”).  In the event that
any such executed waiver is deemed to be unenforceable against such third party,
the Indemnitor shall not be responsible to the extent of any liability for such
third party claims.  The Indemnitor shall have the right to defend against any
such claim with counsel of its choice reasonably satisfactory to the Company if,
within 15 days following written receipt of notice of the claim to the
Indemnitor, the Indemnitor notifies the Company in writing that it shall
undertake such defense.

6.
To the extent that the Underwriters do not exercise their over-allotment option
to purchase up to an additional 3,000,000 Units within 45 days from the date of
the Prospectus (and as further described in the Prospectus) in full, the Sponsor
agrees to forfeit, at no cost, a number of Founder Shares in the aggregate equal
to 750,000 multiplied by a fraction (i) the numerator of which is 3,000,000
minus the number of Units purchased by the Underwriters upon the exercise of
their over-allotment option, and (ii) the denominator of which is 3,000,000. 
For Clarity, the forfeiture  shall yield the result that the Initial
Stockholders will own an aggregate of 20% of the Company’s issued and
outstanding shares of Capital Stock after the Public Offering (assuming, for
purposes of this calculation, that the Initial Stockholders do not purchase any
Units in the Public Offering).

7.
Sponsor and each Insider hereby agrees and acknowledges that: (i) the
Underwriters and the Company would be irreparably injured in the event of a
breach by such Sponsor or an Insider of its, his or her obligations under
paragraphs 1, 2, 3, 4, 5, 6, 8(a), 8(b) and, solely as to each D&O Insider, 10,
as applicable, of this Letter Agreement, (ii) monetary damages may not be an
adequate remedy for such breach and (iii) the non-breaching party shall be
entitled to injunctive relief, in addition to any other remedy that such party
may have in law or in equity, in the event of such breach. The Investors shall
also be entitled to seek injunctive relief, in addition to any other remedy that
such parties may have in law or in equity, in the event of a breach under this
Letter Agreement.

8.
(a)          The Sponsor and each Insider agrees that it, he or she shall not
Transfer any Founder Shares (or shares of Common Stock issuable upon conversion
thereof) until the earlier of (A) one year after the completion of the Company’s
initial Business Combination or (B) subsequent to the Business Combination,
(x) if the last sale price of the Common Stock equals or exceeds $12.00 per
share (as adjusted for stock splits, stock dividends, reorganizations,
recapitalizations and the like) for any 20 trading days within any 30-trading
day period commencing at least 150 days after the Company’s initial Business
Combination or (y) the date on which the Company completes a liquidation,
merger, capital stock exchange, reorganization or other similar transaction that
results in all of the Company’s stockholders having the right to exchange their
shares of Common Stock for cash, securities or other property (the “Founder
Shares Lock-up Period”).

3

--------------------------------------------------------------------------------

(b)          The Sponsor and each Insider agrees that it, he or she shall not
Transfer any Private Placement Warrants (or shares of Common Stock issued or
issuable upon the exercise of the Private Placement Warrants), until 30 days
after the completion of the Company’s initial Business Combination (the “Private
Placement Warrants Lock-up Period”, together with the Founder Shares Lock-up
Period, the “Lock-up Periods”).

(c)          Notwithstanding the provisions set forth in paragraphs 8(a) and
(b), Transfers of the Founder Shares, Private Placement Warrants and shares of
Common Stock issued or issuable upon the exercise or conversion of the Private
Placement Warrants or the Founder Shares and that are held by the Sponsor, any
Insider or any of their permitted transferees (that have complied with this
paragraph 8(c)), are permitted (a) to the Company’s officers or directors, any
affiliates or family members of any of the Company’s officers or directors, any
affiliate of the Sponsor or to any member(s) of the Sponsor, any affiliates of
such members and funds and accounts advised by such members; (b) in the case of
an individual, by gift to a member of such individual’s immediate family or to a
trust, the beneficiary of which is a member of such individual’s immediate
family, an affiliate of such individual or to a charitable organization; (c) in
the case of an individual, by virtue of the laws of descent and distribution
upon death of such person; (d) in the case of an individual, pursuant to a
qualified domestic relations order; (e) by private sales or transfers made in
connection with the consummation of an initial Business Combination at prices no
greater than the price at which the securities were originally purchased; (f) in
the event of the Company’s liquidation prior to the completion of an initial
Business Combination; (g) by virtue of the laws of the State of Delaware or the
Sponsor’s limited liability company agreement upon dissolution of the Sponsor;
or (h) in the event of the Company’s liquidation, merger, capital stock
exchange, reorganization or other similar transaction which results in all of
the Company’s stockholders having the right to exchange their shares of Common
Stock for cash, securities or other property subsequent to the completion of an
initial Business Combination; provided, however, that, in the case of
clauses (a) through (e) or (g), these permitted transferees must enter into a
written agreement with the Company agreeing to be bound by the transfer
restrictions herein.

9.
Prior to the consummation of the initial Business Combination, each of the PIMCO
Investors (collectively) and the CRIS Consortium shall have the right to appoint
one representative to the Board of Directors of the Company and two observers of
the Board of Directors of the Company commencing on the effective date of the
registration statement on Form S-1 related to the Public Offering until the
earlier to occur of (i) any Business Combination and (ii) either the CRIS
Consortium or the PIMCO Investors transferring or disposing of any of their
membership interests in the Sponsor, other than to an affiliate of such
investor.  The CRIS Consortium shall have the right to nominate three
independent directors for election to the Board of Directors of the Company,
with such candidates subject to the approval of the PIMCO Investors (such
approval not to be unreasonably withheld).  The Sponsor agrees to vote the
Founder Shares in favor of (a) each of the CRIS Consortium’s and the PIMCO
Investors’ appointees to the Board when each of the CRIS Consortium and the
PIMCO Investors’ appointees are up for election and (b) the independent director
nominees designated by the CRIS Consortium and approved by the PIMCO Investors
when each of such nominees is up for election.

10.
Each of the Insiders who is or is nominated to be a director or officer of the
Company (each, a “D&O Insider”) agrees to serve in such capacity until the
earlier of the consummation by the Company of an initial Business Combination,
the liquidation of the Company, or his or her removal, death or incapacity.  The
Sponsor and each D&O Insider represents and warrants that it, he or she has
never been suspended or expelled from membership in any securities or
commodities exchange or association or had a securities or commodities license
or registration denied, suspended or revoked.  Each D&O Insider’s biographical
information furnished to the Company (including any such information included in
the Prospectus) is true and accurate in all material respects and does not omit
any material information with respect to the D&O Insider’s background and
contains all of the information required to be disclosed pursuant to Item 401 of
Regulation S-K, promulgated under the Securities Act.  Each D&O Insider’s
questionnaire furnished to the Company and the Representatives is true and
accurate in all material respects.  Each D&O Insider represents and warrants
that: it, he or she is not subject to or a respondent in any legal action for,
any injunction, cease-and-desist order or order or stipulation to desist or
refrain from any act or practice relating to the offering of securities in any
jurisdiction; it, he or she has never been convicted of, or pleaded guilty to,
any crime (i) involving fraud, (ii) relating to any financial transaction or
handling of funds of another person, or (iii) pertaining to any dealings in any
securities and it, he or she is not currently a defendant in any such criminal
proceeding.

4

of a loan or other compensation prior to, or in connection with any services
rendered in order to effectuate, the consummation of the Company’s initial
Business Combination (regardless of the type of transaction that it is).

12.
The Company, the Sponsor, each Investor and each Insider represents and
warrants, severally and not jointly, that it, he or she has full right and
power, without violating any agreement to which it, he or she is bound
(including, without limitation, any non-competition or non-solicitation
agreement with any employer or former employer), to enter into this Letter

or provisions of this Letter Agreement shall be in writing and shall be sent by
