Re:
Initial Public Offering


 


Ladies
and Gentlemen:


 


This letter (the “Letter Agreement”)
is being delivered to you in accordance with the Underwriting Agreement (the “Underwriting Agreement”)
entered into by and between Cascade Acquisition Corp., a Delaware corporation (the “Company”) and Credit
Suisse Securities (USA) LLC and Morgan Stanley & Co. LLC, as representatives (the “Representatives”)
of the several underwriters named in Schedule A thereto (the “Underwriters”), relating to an underwritten
initial public offering (the “IPO”) of the Company’s units (the “Units”), each
unit comprised of 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 exercisable for one share of Common Stock. Certain capitalized terms
used herein are defined in paragraph 12 hereof.


 


In
order to induce the Company and the Underwriters to enter into the Underwriting Agreement and to proceed with the IPO, and in
recognition of the benefit that such IPO will confer upon the undersigned, and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the undersigned hereby agrees with the Company as follows:


 


	 	1.	If
    the Company solicits approval of its stockholders of a Business Combination, the undersigned will vote all shares of Common
    Stock beneficially owned by him or her, whether acquired before, in or after the IPO, in favor of such Business Combination.
	 	 	 
	 	2.	In
the event that the Company does not complete a Business Combination within the time period, including any extension, set forth
in the Company’s amended and restated certificate of incorporation, as the same may be further amended from time to time (the
“Charter”), the undersigned will, as promptly as possible, take all necessary actions 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, redeem the IPO Shares, 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 tax obligations, if any (less up to $100,000 of interest to pay dissolution expenses), divided by the number
of the then outstanding IPO Shares, which redemption will completely extinguish public stockholders’ rights as stockholders (including
the right to receive further liquidation distributions, if any), 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, liquidate and dissolve,
subject in each case to the Company’s obligations under Delaware law to provide for claims of creditors and the requirements of
other applicable law. The undersigned hereby waives any and all right, title, interest or claim of any kind in or to any distribution
of the Trust Account and any remaining net assets of the Company as a result of such liquidation with respect to the Founder Shares
owned by the undersigned. However, if any of the undersigned have acquired IPO Shares in or after the IPO, they will be entitled
to liquidating distributions from the Trust Account with respect to such IPO Shares in the event that the Company does not complete
a Business Combination within the time period set forth in the Charter. The undersigned acknowledges and agrees that there will
be no distribution from the Trust Account with respect to any warrants, all rights of which will terminate on the Company’s liquidation.



 






     


     


    

 


	 	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, which is a member of the Financial Industry Regulatory Authority, or an independent
    accounting firm that such Business Combination is fair to the Company’s unaffiliated stockholders from a financial point of
    view.
	 	 	 
	 	4.	None
    of the undersigned, any member of the family of any of the undersigned, or any affiliate of the undersigned will be entitled
    to receive and will not accept any compensation or other cash payment from the Company prior to, or for services rendered
    in order to effectuate, the completion of the Business Combination; provided that the Company shall be allowed to make the
    payments set forth in the Registration Statement adjacent to the caption “Prospectus Summary-The Offering-Limited payments
    to insiders.”
	 	 	 
	 	5.	(a)
    The undersigned agrees not to Transfer the Founder Shares (or any shares of Common Stock issuable upon conversion thereof)
    (except to certain permitted transferees as described in the Registration Statement or herein) (the “Lockup”)
    until the earlier to occur of: (1) one year after the completion of the Company’s initial Business Combination or (2) subsequent
    to the Company’s initial Business Combination, (x) if the last reported sale price of Common Stock equals or exceeds $12.00
    per share (as adjusted for stock splits, stock capitalizations, 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 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.


 


(b)
Notwithstanding the provisions set forth in paragraphs 5(a) and 5(c), during the period commencing on the effective date of the
Underwriting Agreement and ending 180 days after such date, the undersigned will not, without the prior written consent of the
Representatives pursuant to the Underwriting Agreement, (i) sell, offer to sell, contract or agree to sell, hypothecate, pledge,
hedge or otherwise dispose of or agree to dispose of (or enter into any transaction that is designed to, or might reasonably be
expected to, result in the disposition (whether by actual disposition or effective economic disposition due to cash settlement
or otherwise) by the undersigned or any affiliate of the undersigned or any person in privity with the undersigned or any affiliate
of the undersigned), directly or indirectly, including the filing (or participation in the filing) of a registration statement
with the Securities and Exchange Commission (the “SEC”) in respect of, 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 SEC promulgated thereunder
with respect to, any Units, shares of Common Stock, Founder Shares or warrants or any securities convertible into, or exercisable,
or exchangeable for, shares of Common Stock 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, including the filing of a registration statement, specified in clause (i) or (ii). The
provisions of this paragraph will not apply (i) to the transfer of Founder Shares to any independent director appointed or elected
to the Company’s board of directors before or after the IPO or (ii) if the release or waiver is effected solely to permit a transfer
not for consideration and, in each case 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.


  


(c) The undersigned agrees not to Transfer any Private Placement
Warrants, Working Capital Warrants, or Extension Loan Warrants (or shares of Common Stock issued or issuable upon the exercise
of such warrants), until 30 days after the completion of the Company’s initial Business Combination.

(d) Notwithstanding the provisions set forth in paragraphs 5(a)
and (c), Transfers by the undersigned of the Founder Shares, Private Placement Warrants, Working Capital Warrants, and Extension
Loan Warrants and shares of Common Stock issued or issuable upon the exercise of the Private Placement Warrants, Working Capital
Warrants, and Extension Loan Warrants, or conversion of the Founder Shares are permitted (i) to the Company’s officers or directors,
any affiliates or family members of any of the Company’s officers or directors, to Cascade Acquisition Holdings LLC, a Delaware
limited liability company (the “Sponsor”), any members of the Sponsor or their affiliates, any affiliates
of the Sponsor, or any employees of such affiliates; (ii) in the case of an individual, by gift to a member of the individual’s
immediate family or to a trust, the beneficiary of which is a member of one of the individual’s immediate family, an affiliate
of such person or to a charitable organization; (iii) in the case of an individual, by virtue of laws of descent and distribution
upon death of the individual; (iv) in the case of an individual, pursuant to a qualified domestic relations order; (v) by private
sales or transfers made in connection with the completion of the Business Combination at prices no greater than the price at which
the Founder Shares, Private Placement Warrants, Working Capital Warrants, and Extension Loan Warrants, or shares of Common Stock,
as applicable, were originally purchased; (vi) by virtue of the Sponsor’s organizational documents upon liquidation or dissolution
of the Sponsor; (vii) to the Company for no value for cancellation in connection with the completion of the Business Combination;
(viii) in the event of the Company’s liquidation prior to the completion of a Business Combination; or (ix) in the event of completion
of a liquidation, merger, share exchange 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 a Business
Combination; provided, however, that in the case of clauses (i) through (vii) these permitted transferees must enter
into a written agreement agreeing to be bound by the restrictions herein. For the avoidance of doubt, the transfers of Founder
Shares, Private Placement Warrants, Working Capital Warrants, and Extension Loan Warrants, and shares of Common Stock issued or
issuable upon the exercise of the Private Placement Warrants, Working Capital Warrants, and Extension Loan Warrants, or conversion
of the Founder Shares shall be permitted regardless of whether a filing under Section 16(a) of the Exchange Act shall be required
or shall be voluntarily made with respect to such transfers.


 


(e)
The undersigned acknowledges and agrees that if, in order to complete any Business Combination, the holders of Founder Shares
or Private Placement Warrants are required to contribute back to the capital of the Company a portion of any such securities to
be cancelled by the Company or transfer any such securities to third parties, the undersigned will contribute back to the capital
of the Company or transfer to such third parties, at no cost, a proportionate number of Founder Shares or Private Placement Warrants,
as applicable, pro rata with the other holders of Founder Shares or Private Placement Warrants, as applicable.


 


	 	6.	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 Insider of his or her obligations under paragraphs 1, 2, 3, 4, 5, 7, 10 and 11 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
    seek injunctive relief, in addition to any other remedy that such party may have in law or in equity, in the event of such
    breach.
	 	 	 
	 	7.	In
    order to minimize potential conflicts of interest that may arise from multiple corporate affiliations, the undersigned hereby
    agrees that until the earliest of the Company’s initial Business Combination or liquidation, the undersigned shall present
    to the Company for its consideration, prior to presentation to any other entity, any target business that has a fair market
    value of at least 80% of the assets held in the Trust Account (excluding the amount of deferred underwriting discounts held
    in trust and taxes payable on the interest earned on the trust account), subject to any existing or future fiduciary or contractual
    obligations the undersigned might have.

	 	11.
