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 between Osiris Acquisition Corp., a Delaware corporation (the “Company”), and Jefferies LLC, (the
 “Underwriter”), relating to an underwritten initial public offering (the “Public Offering”),
of 28,750,000 of the Company’s units (including up to 3,750,000 units that may be purchased to cover over-allotments, if
any) (the “Units”), each 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 (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, as described
in the Prospectus (as defined below). The Units will be sold in the Public Offering pursuant to a registration statement on Form
S-1 and 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 11 hereof.


 


In order to induce the Company and the Underwriter
to enter into the Underwriting Agreement and to proceed with the Public Offering and for other good and valuable consideration,
the receipt and sufficiency of which are hereby acknowledged, Osiris Sponsor, LLC (the “Sponsor”), and each
of the undersigned individuals, each of whom is a member of the Company’s board of directors and/or management team (each,
an “Insider” and, collectively, the “Insiders”), hereby severally (and not jointly and severally)
agrees with the Company as follows:


 


1.                 
The Sponsor and each Insider agrees that if the Company seeks stockholder approval of a proposed Business Combination (as
defined below), then in connection with such proposed Business Combination, it, he or she shall (i) vote any shares of Capital
Stock (as defined below) owned by it, him or her in favor of such proposed Business Combination and (ii) not redeem any shares
of Common Stock owned by it, him or her in connection with such stockholder approval. If the Company seeks to consummate a proposed
Business Combination by engaging in a tender offer, the Sponsor and each Insider agrees that it, he or she will not sell or tender
any shares of Capital Stock owned by it, him or her to the Company in connection therewith.


 






     


     


    

 


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 (the “Completion Window”), 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, less amounts withdrawn to pay the Company’s taxes (“Permitted Withdrawals”) and 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’ (as defined below) rights as stockholders (including the
right to receive further liquidating 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 the requirements of other applicable law. The Sponsor and each Insider
agrees to not propose any amendment to the Charter that would modify the substance or timing of the Company’s
obligation to redeem 100% of the Offering Shares if the Company does not complete a Business Combination within the
Completion Window or with respect to any other material provisions relating to stockholders’ rights or pre-initial
Business Combination activity, unless the Company provides its Public Stockholders with the opportunity to redeem their
Offering Shares 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 (net of Permitted Withdrawals), 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 as a result
of any liquidation of the Company with respect to the Founder Shares (as defined blow) held by it, him or her. The Sponsor and
each Insider hereby further 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 a stockholder vote to approve such Business Combination or in the context of a tender offer made by
the Company to purchase shares of Common Stock (although the Sponsor, the Insiders and their respective affiliates shall be entitled
to redemption and 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 or in connection with a stockholder vote to approve an amendment to
the Charter to modify the substance or timing of the Company’s obligation 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 with respect to any other material
provisions relating to stockholders' rights or pre-initial Business Combination activity).

3.                 
 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 Underwriter, (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 option 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 Capital Stock, Warrants or any securities convertible into, or exercisable, or exchangeable for, shares of
Common Stock owned by it, him or her, or (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 Capital Stock, 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). Each of the Insiders and the Sponsor acknowledges and agrees that, prior to the effective date
of any release or waiver of the restrictions set forth in this paragraph 3 or paragraph 7 below, the Company shall announce the
impending release or waiver by press release through a major news service at least two business days before the effective date
of the release or waiver. Any such release or waiver granted shall only be effective two business days after the publication date
of such press release. The provisions of this paragraph will not apply if (i) the release or waiver is effected solely to permit
a transfer of securities without consideration and (ii) 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.


 


4.                  In
the event of the liquidation of the Trust Account, the Sponsor (which for purposes of clarification shall not extend to any
other shareholders, members or managers of the Sponsor or any other Insider) 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, or any claim whatsoever) to which the Company may become subject as a result of any claim by (i) any
third party (other than the Company’s independent accountants) for services rendered or products sold to the Company or
(ii) a prospective target business with which the Company has entered into a letter of intent, confidentiality or other
similar agreement for a Business Combination (a “Target”); provided, however, that such
indemnification of the Company by the Sponsor (x) shall apply only to the extent necessary to ensure that such claims by a
third party (other than the Company’s independent accountants) for services rendered 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 or (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
Permitted Withdrawals, (y) shall not apply to any claims by a third party (including a Target) that 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) shall not apply to
any claims under the Company’s indemnity of the Underwriter against certain liabilities, including liabilities under
the Securities Act of 1933, as amended. The Sponsor 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
Sponsor, the Sponsor notifies the Company in writing that it shall undertake such defense. For the avoidance of doubt, none
of the Company’s officers or directors will indemnify the Company for claims by third parties, including, without
limitation, claims by vendors and prospective target businesses.

5.                 
To the extent that the Underwriter does not exercise its over-allotment option to purchase up to an additional 3,750,000
Units within 45 days from the date of the Prospectus (and as further described in the Prospectus), the Sponsor, Omar Johnson and
Benjamin F. Rattner agree to forfeit, at no cost, an aggregate number of Founder Shares equal to the product of 937,500
multiplied by a fraction, (i) the numerator of which is 3,750,000 minus the number of Units purchased by the Underwriter upon the
exercise of its over-allotment option, and (ii) the denominator of which is 3,750,000. The allocation of the Founder Share forfeitures
shall be as follows: 85% from Sponsor, 5% for Omar Johnson and 10% from Benjamin F. Rattner. The forfeiture will be adjusted to
the extent that the over-allotment option is not exercised in full by the Underwriter so that the Initial Stockholders (as defined
below) will own an aggregate of 20.0% of the Company’s issued and outstanding shares of Capital Stock after the Public Offering.
To the extent that the size of the Public Offering is increased or decreased, the Company will effect a capitalization or share
repurchase, redemption or stock split or other appropriate mechanism, as applicable, immediately prior to the consummation of the
Public Offering in such amount as to maintain the ownership of the Capital Stock of the Initial Stockholders prior to the Public
Offering at 20.0% of the Company’s issued and outstanding Capital Stock upon the consummation of the Public Offering. In
connection with such increase or decrease in the size of the Public Offering, (A) references to 3,750,000 in the numerator and
denominator of the formula in the first sentence of this paragraph shall be changed to a number equal to 15% of the number of shares
included in the Units issued in the Public Offering and (B) the reference to 937,500 in the
formula set forth in the immediately preceding sentence shall be adjusted to such number of Founder Shares that the Sponsor would
have to return to the Company in order to hold (with all of the Initial Stockholders) an aggregate of 20.0% of the Company’s
issued and outstanding Capital Stock after the Public Offering.


 


6.                 
The Sponsor and each Insider hereby agrees and acknowledges that: (i) the Underwriter and the Company would be irreparably
injured in the event of a breach by the Sponsor or an Insider of its, his or her obligations under paragraphs 1, 2, 3, 4, 5, 7(a),
7(b), and 9, 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.


 


7.              (a)             
Subject to the exceptions set forth herein, the Sponsor and each Insider agrees that it, he or she shall not Transfer (as
defined below) 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 closing 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”).


 






    4


     


    

 


(b)              
Subject to the exceptions set forth herein, the Sponsor and each Insider agrees that it, he or she shall not Transfer any
Private Placement Warrants (as defined below) or shares of Common Stock issued or issuable upon the exercise of the Private Placement
Warrants, until 30 days after the completion of a 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 3 and 7(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 7(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 members of the Sponsor, or any affiliates of the Sponsor; (b) in the case of such person,
transfers by gift to a member of the individual’s immediate family, to a trust, the beneficiary of which is a member of the
individual’s immediate family or an affiliate of such person, or to a charitable organization; (c) in the case of an individual,
transfers by virtue of laws of descent and distribution upon death of the individual; (d) in the case of an individual, transfers
pursuant to a qualified domestic relations order; (e) transfers by private sales or transfers made in connection with any forward
purchase agreement or in connection with the consummation of the Company’s Business Combination at prices no greater than
the price at which the securities were originally purchased; (f) transfers in the event of the Company’s liquidation prior
to the completion of the Company’s initial Business Combination; (g) transfers by virtue of the laws of the State of Delaware
or the Sponsor’s limited liability company agreement upon dissolution of the Sponsor; (h) in the event of the Company’s
completion of a liquidation, merger, stock exchange, reorganization or other similar transaction which results in all of the Company’s
Public Stockholders having the right to exchange their shares of Class A common stock for cash, securities or other property subsequent
to the completion of the initial Business Combination; and (i) to a nominee or custodian of a person or entity to whom a disposition
or transfer would be permissible under clauses (a) through (h) above; provided, however, that in the case of clauses
(a) through (e) and (i), these permitted transferees must enter into a written agreement with the Company agreeing to be bound
by the transfer restrictions herein and the other restrictions contained in this Agreement (including provisions relating to voting,
the Trust Account and liquidating distributions).

8.                 
 The Sponsor and each 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 such Insider’s biographical information furnished to the Company (including any such information included
in the Prospectus) is true and accurate in all respects and does not omit any material information with respect to such Insider’s
background. Each Insider’s questionnaire furnished to the Company is true and accurate in all respects. The Sponsor and each
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.


 


9.                 
Except as disclosed in the Prospectus, neither the Sponsor nor any Insider nor any affiliate of the Sponsor or any Insider,
nor any director or officer of the Company, shall receive from the Company any finder’s fee, reimbursement, consulting fee,
monies in respect of any repayment 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), other than the following, none of which will be made from the proceeds held in the Trust Account prior to the completion
of the initial Business Combination: repayment of a loan and advances of up to $300,000 made to the Company by the Sponsors to
cover expenses related to the organization of the Company and the Public Offering; reimbursement for any reasonable out-of-pocket expenses
related to identifying, investigating and consummating an initial Business Combination, and repayment of loans, if any, and on
such terms as to be determined by the Company from time to time, made by the Sponsor or certain of the Company’s officers
and directors to finance transaction costs in connection with an intended initial Business Combination, provided, that, if the
Company does not consummate an initial Business Combination, a portion of the working capital held outside the Trust Account may
be used by the Company to repay such loaned amounts so long as no proceeds from the Trust Account are used for such repayment.
Up to $1,500,000 of such loans may be convertible into warrants of the post Business Combination entity at a price of $1.00 per
warrant at the option of the lender. Such warrants would be identical to the Private Placement Warrants, including as to exercise
price, exercisability and exercise period.


 


10.             
The Sponsor and each Insider has full right and power, without violating any agreement to which it is bound (including,
without limitation, any non-competition or non-solicitation agreement with any employer or former employer), to enter into this
Letter Agreement and, as applicable, to serve as an officer and/or a director on the board of directors of the Company and hereby
consents to being named in the Prospectus as an officer and/or a director of the Company.

Except as otherwise provided herein, no party hereto may assign either this Letter Agreement or any of its rights, interests,
or obligations hereunder without the prior written consent of the other parties. Any purported assignment in violation of this
paragraph shall be void and ineffectual and shall not operate to transfer or assign any interest or title to the purported assignee.

17.             
This Letter Agreement shall be governed by and construed and enforced in accordance with the laws of the State of New York,

The parties hereto (i) all agree that any action, proceeding, claim or dispute arising out of, or relating in any way to, this
