THIS LOCK-UP AGREEMENT (this
“Agreement”) is made and entered into as of [●], 2021 by and between (i) Blue Water Acquisition Corp.,
a Delaware corporation (together with its successors, the “Parent”), and (ii) the undersigned (“Holder”).
Any capitalized term used but not defined in this Agreement will have the meaning ascribed to such term in the Merger Agreement.


 


WHEREAS, on April 27,
2021, (i) Parent, (ii) Blue Water Merger Sub Corp., a Delaware corporation and a wholly-owned subsidiary of Parent (“Merger
Sub”), and (iii) Clarus Therapeutics, Inc., a Delaware corporation (together with its successors, the “Company”),
entered into that certain Agreement and Plan of Merger (as amended from time to time in accordance with the terms thereof, the “Merger
Agreement”), pursuant to which, among other matters, upon the consummation of the transactions contemplated thereby (the
“Closing”), Merger Sub will merge with and into the Company, with the Company continuing as the surviving entity
(the “Merger”), and as a result of which, all of the issued and outstanding capital stock of the Company immediately
prior to the Closing shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, in exchange for the
right to receive the Closing Payment Shares, all upon the terms and subject to the conditions set forth in the Merger Agreement and in
accordance with the applicable provisions of the of the DGCL;


 


WHEREAS, as of the
date hereof, Holder is a holder of Company Securities in such amounts and classes or series as set forth underneath Holder’s name
on the signature page hereto; and


 


WHEREAS, pursuant to
the Merger Agreement, and in view of the valuable consideration to be received by Holder thereunder, the parties desire to enter into
this Agreement, pursuant to which the Closing Payment Shares received by Holder in the Merger as set forth underneath Holder’s name
on the signature page hereto (all such securities, together with any securities paid as dividends or distributions with respect to such
securities or into which such securities are exchanged or converted, the “Restricted Securities”), shall become
subject to limitations on disposition as set forth herein.


 






     


     


    

 


NOW, THEREFORE, in
consideration of the premises set forth above, which are incorporated in this Agreement as if fully set forth below, and intending to
be legally bound hereby, the parties hereby agree as follows:


 


1. Lock-Up Provisions.


 


(a) Holder hereby agrees not
to, during the period (the “Lock-Up Period”) commencing from the Closing and ending on the earlier of (x) 180
days after the date of the Closing, and (y)  the date after the Closing on which Parent consummates a liquidation, merger, capital
stock exchange, reorganization or other similar transaction with an unaffiliated third party that results in all of Parent’s stockholders
having the right to exchange their equity holdings in Parent for cash, securities or other property (a “Change of Control”):
(i) lend, offer, pledge, hypothecate, encumber, donate, assign, sell, contract to sell, sell any option or contract to purchase, purchase
any option or contract to sell, grant any option, right or warrant to purchase, or otherwise transfer or dispose of, directly or indirectly,
any Restricted Securities, (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 the Restricted Securities, or (iii) publicly disclose the intention to do any of the foregoing,
whether any such transaction described in clauses (i), (ii) or (iii) above is to be settled by delivery of Restricted Securities or other
securities, in cash or otherwise (any of the foregoing described in clauses (i), (ii) or (iii), a “Prohibited Transfer”).
The foregoing sentence shall not apply to the transfer of any or all of the Restricted Securities owned by Holder (I) by gift, will or
intestate succession upon the death of Holder, (II) to any Permitted Transferee (as defined below) or (III) pursuant to a court order
or settlement agreement related to the distribution of assets in connection with the dissolution of marriage or civil union; provided,
however, that in any of cases (I), (II) or (III) it shall be a condition to such transfer that the transferee executes and delivers to
Parent an agreement stating that the transferee is receiving and holding the Restricted Securities subject to the provisions of this Agreement
applicable to Holder, and there shall be no further transfer of such Restricted Securities except in accordance with this Agreement. As
used in this Agreement, the term “Permitted Transferee” shall mean: (A) the members of Holder’s immediate
family (for purposes of this Agreement, “immediate family” shall mean with respect to any natural person, any of the following:
such person’s spouse, the siblings of such person and his or her spouse, and the direct descendants and ascendants (including adopted
and step children and parents) of such person and his or her spouses and siblings), (B) any trust for the direct or indirect benefit of
Holder or the immediate family of Holder, (C) if Holder is a trust, the trustor or beneficiary of such trust or to the estate of a beneficiary
of such trust, (D) if Holder is an entity, as a distribution to limited partners, shareholders, members of, or owners of similar equity
interests in Holder, and (E) any Affiliate of Holder. Further, the restrictions set forth in this Agreement shall not prohibit Holder
from (1) entering into any voting, support, lock-up or similar agreement pursuant to which Holder may agree to transfer, sell, tender
or otherwise dispose of Restricted Securities in connection with a Change of Control subject to the consummation thereof or (2) establishing
a trading plan pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended, for the transfer of Restricted Securities
provided that such plan does not provide for the transfer of Restricted Securities during the Lock-Up Period.


 


(b) If any Prohibited Transfer
is made or attempted contrary to the provisions of this Agreement, such purported Prohibited Transfer shall be null and void ab initio,
and Parent shall refuse to recognize any such purported transferee of the Restricted Securities as one of its equity holders for any purpose.
In order to enforce this Section 1, Parent may impose stop-transfer instructions with respect to the Restricted Securities
of Holder (and Permitted Transferees and assigns thereof) until the end of the Lock-Up Period.


 


(c) During the Lock-Up Period,
each certificate evidencing any Restricted Securities may be stamped or otherwise imprinted with a legend in substantially the following
form, in addition to any other applicable legends:


 


“THE SECURITIES REPRESENTED BY THIS
CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN A LOCK-UP AGREEMENT, DATED AS OF [●], 2021, BY AND BETWEEN THE
ISSUER OF SUCH SECURITIES (THE “ISSUER”) AND THE ISSUER’S SECURITY HOLDER NAMED THEREIN, AS AMENDED. A COPY OF SUCH
LOCK-UP AGREEMENT WILL BE FURNISHED WITHOUT CHARGE BY THE ISSUER TO THE HOLDER HEREOF UPON WRITTEN REQUEST.”


 


(d) For the avoidance of any
doubt, Holder shall retain all of its rights as a stockholder of Parent during the Lock-Up Period, including the right to vote any Restricted
Securities.


 


2. Miscellaneous.


 


(a) Termination of Merger
Agreement. This Agreement shall be binding upon Holder upon Holder’s execution and delivery of this Agreement, but this Agreement
shall only become effective upon the Closing. Notwithstanding anything to the contrary contained herein, in the event that the Merger
Agreement is terminated in accordance with its terms prior to the Closing, this Agreement and all rights and obligations of the parties
hereunder shall automatically terminate and be of no further force or effect.


 






    2


     


    

 


(b) Binding Effect; Assignment.
This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of the parties hereto and their respective
permitted successors and assigns. This Agreement and all obligations of Holder are personal to Holder and may not be transferred or delegated
by Holder at any time. Parent may freely assign any or all of its rights under this Agreement, in whole or in part, to any successor entity
(whether by merger, consolidation, equity sale, asset sale or otherwise) without obtaining the consent or approval of Holder.


 


(c) Third Parties. Nothing
contained in this Agreement or in any instrument or document executed by any party in connection with the transactions contemplated hereby
shall create any rights in, or be deemed to have been executed for the benefit of, any person or entity that is not a party hereto or
thereto or a successor or permitted assign of such a party.


 


(d) Arbitration.


 


(i) The parties
shall promptly submit any dispute, claim, or controversy arising out of or relating to this Agreement (including with respect to the meaning,
effect, validity, termination, interpretation, performance, or enforcement of this Agreement) or any alleged breach thereof (including
any action in tort, contract, equity, or otherwise), to binding arbitration before one arbitrator (the “Arbitrator”).
Binding arbitration shall be the sole means of resolving any dispute, claim, or controversy arising out of or relating to this Agreement
(including with respect to the meaning, effect, validity, termination, interpretation, performance or enforcement of this Agreement) or
any alleged breach thereof (including any claim in tort, contract, equity, or otherwise).


 


(ii) If the parties
cannot agree upon the Arbitrator, the Arbitrator shall be selected by the New York, New York chapter head of the American Arbitration
Association upon the written request of any party. The Arbitrator shall be selected within thirty (30) days of the written request of
any party.


 


(iii) The laws of
the State of Delaware shall apply to any arbitration hereunder. In any arbitration hereunder, this Agreement shall be governed by the
laws of the State of Delaware applicable to a contract negotiated, signed and to be performed wholly in the State of Delaware, which laws
the Arbitrator shall apply in rendering his decision. The Arbitrator shall issue a written decision, setting forth findings of fact and
conclusions of law, within sixty (60) days after he shall have been selected. The Arbitrator shall have no authority to award punitive
or other exemplary damages.


 


(iv) The arbitration
shall be held in New York, New York in accordance with and under the then-current provisions of the rules of the American Arbitration
Association, except as otherwise provided herein.


 


(v) On application
to the Arbitrator, any party shall have rights to discovery to the same extent as would be provided under the Federal Rules of Civil Procedure,
and the Federal Rules of Evidence shall apply to any arbitration under this Agreement; provided, however, that the Arbitrator
shall limit any discovery or evidence such that his decision shall be rendered within the period referred to in Section 2(d)(iii).


 


(vi) The Arbitrator
may, at his discretion and at the expense of the party who will bear the cost of the arbitration, employ experts to assist him in his
determinations.


 






    3


     


    

 


(vii) The costs
of the arbitration proceeding and any proceeding in court to confirm any arbitration award or to obtain relief as provided in Section
2(d)(viii), as applicable (including actual attorneys’ fees and costs), shall be borne by the unsuccessful party and shall be
awarded as part of the Arbitrator’s decision, unless the Arbitrator shall otherwise allocate such costs in such decision. The determination
of the Arbitrator shall be final and binding upon the parties and not subject to appeal.


 


(viii) Any judgment
upon any award rendered by the Arbitrator may be entered in and enforced by any court of competent jurisdiction. The parties expressly
consent to the non-exclusive jurisdiction of the courts (Federal and state) in Delaware, to enforce any award of the Arbitrator or to
render any provisional, temporary, or injunctive relief in connection with or in aid of the arbitration. The parties expressly consent
to the personal and subject matter jurisdiction of the Arbitrator to arbitrate any and all matters to be submitted to arbitration hereunder.
None of the parties hereto shall challenge any arbitration hereunder on the grounds that any party necessary to such arbitration (including
the parties hereto) shall have been absent from such arbitration for any reason, including that such party shall have been the subject
of any bankruptcy, reorganization, or insolvency proceeding.


 


(ix) The parties
shall indemnify the Arbitrator and any experts employed by the Arbitrator and hold them harmless from and against any claim or demand
arising out of any arbitration under this Agreement or any agreement contemplated hereby, unless resulting from the gross negligence or
willful misconduct of the person indemnified; provided, however, that Parent’s indemnification obligations under this Section
2(d)(ix) shall be subject to the prior agreement of any applicable indemnitee to be bound by a customary waiver of claims against
Parent’s Trust Account.


 


(x) Notwithstanding
anything herein to the contrary, the parties agree that irreparable damage would occur if any of the provisions of this Agreement were
not performed in accordance with their specific terms or were otherwise breached. It is accordingly agreed that the parties shall be entitled
to seek an injunction or injunctions, specific performance and other equitable relief to prevent breaches of this Agreement and to enforce
specifically the terms and provisions of this Agreement, without the requirement to post any bond or other security or to prove that money
damages would be inadequate. The parties expressly consent to the non-exclusive jurisdiction of the courts (Federal and state) in Delaware
to render such relief and to enforce specifically the terms and provisions of this Agreement.


 


(e) WAIVER OF JURY
TRIAL; Representation.


 


(i) THE PARTIES
TO THIS AGREEMENT HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVE ANY RIGHT EACH SUCH PARTY MAY HAVE TO TRIAL BY JURY IN ANY ACTION
OF ANY KIND OR NATURE, IN ANY COURT IN WHICH AN ACTION MAY BE COMMENCED, ARISING OUT OF OR IN CONNECTION WITH THIS AGREEMENT. NO PARTY
SHALL BE AWARDED PUNITIVE OR OTHER EXEMPLARY DAMAGES RESPECTING ANY DISPUTE ARISING UNDER THIS AGREEMENT.


 


(ii) Each of the
parties to this Agreement acknowledges that it has been represented in connection with the signing of the foregoing waiver by independent
legal counsel selected by it and that such party has discussed the legal consequences and import of such waiver with legal counsel. Each
of the parties to this Agreement further acknowledges that it has read and understands the meaning of such waiver and grants such waiver
knowingly, voluntarily, without duress and only after consideration of the consequences of this waiver with legal counsel.


 






    4


     


    

 


(f) Authorization on Behalf
of Parent.  The parties acknowledge and agree that notwithstanding anything to the contrary contained in this Agreement, any
and all determinations, actions or other authorizations under this Agreement on behalf of Parent after the Closing, including enforcing
Parent’s rights and remedies under this Agreement, or providing any waivers or amendments with respect to this Agreement or the
provisions hereof, shall solely be made, taken and authorized by the vote or consent of a majority of the Disinterested Directors. 
For purposes hereof, a “Disinterested Director” will mean an independent director disinterested in this Agreement
or the Merger Agreement (i.e., such independent director is not a Company Securityholder, an Affiliate of a Company Securityholder, or
an officer, director, manager, employee, trustee or beneficiary of a Company Securityholder, nor an immediate family member of any of
the foregoing) then serving on Parent’s board of directors. Without limiting the foregoing, in the event that Holder or Holder’s
Affiliate serves as a director, officer, employee or other authorized agent of Parent or any of its current or future Affiliates, Holder
and/or Holder’s Affiliate shall have no authority, express or implied, to act or make any determination on behalf of Parent or any
of its current or future Affiliates in connection with this Agreement or any dispute or Action with respect hereto.

feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa; (ii) “including”

(i) Amendments and Waivers.
Any term of this Agreement may be amended and the observance of any term of this Agreement may be waived (either generally or in a particular
instance, and either retroactively or prospectively) only with the written consent of Parent and Holder. No failure or delay by a party
in exercising any right hereunder shall operate as a waiver thereof. No waivers of or exceptions to any term, condition, or provision
of this Agreement, in any one or more instances, shall be deemed to be or construed as a further or continuing waiver of any such term,
condition, or provision.


 


(j) Severability. In
case any provision in this Agreement shall be held invalid, illegal or unenforceable in a jurisdiction, such provision shall be modified
or deleted, as to the jurisdiction involved, only to the extent necessary to render the same valid, legal and enforceable, and the validity,
legality and enforceability of the remaining provisions hereof shall not in any way be affected or impaired thereby nor shall the validity,
legality or enforceability of such provision be affected thereby in any other jurisdiction. Upon such determination that any term or other
provision is invalid, illegal or incapable of being enforced, the parties will substitute for any invalid, illegal or unenforceable provision
a suitable and equitable provision that carries out, so far as may be valid, legal and enforceable, the intent and purpose of such invalid,
illegal or unenforceable provision.

or any Additional Agreement. Notwithstanding the foregoing, nothing in this Agreement shall limit any of the rights or remedies of Parent
or any of the obligations of Holder under any other agreement between Holder and Parent or any certificate or instrument executed by Holder
in favor of Parent, and nothing in any other agreement, certificate or instrument shall limit any of the rights or remedies of Parent
or any of the obligations of Holder under this Agreement.
