Bicycle
Therapeutics plc Form of preference Shares Warrant Agreement

 

This
Preference Shares Warrant Agreement (this “Agreement”), dated as of [●], between Bicycle
Therapeutics plc, a public limited company incorporated under the laws of England and Wales (the “Company”),
and [●], a [corporation] [national banking association] organized and existing under the laws of [●] and having a
corporate trust office in [●], as warrant agent (the “Warrant Agent”).

 

Whereas,
the Company proposes to sell [If Warrants are sold with other securities — [title of such other
securities being offered] (the “Other Securities”) with] warrant certificates evidencing one or
more warrants (the “Warrants” or, individually, a “Warrant”) representing
the right to subscribe for [title of Preference Shares purchasable through exercise of Warrants] of the Company, nominal
value £[Ÿ] per share (the “Warrant
Securities”), such warrant certificates and other warrant certificates issued pursuant to this Agreement being
herein called the “Warrant Certificates”; and

 

Whereas,
the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing so to act, in
connection with the issuance, registration, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this
Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the terms and conditions
on which they may be issued, registered, transferred, exchanged, exercised and replaced.

 

Now
Therefore, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree
as follows:

 

Article 1

 

ISSUANCE
OF WARRANTS AND EXECUTION AND

DELIVERY OF WARRANT CERTIFICATES

 

1.1            Issuance
of Warrants. [If Warrants alone —Upon issuance, each Warrant Certificate shall evidence one or more
Warrants.] [If Other Securities and Warrants —Warrant Certificates will be issued in connection with the
issuance of the Other Securities but shall be separately transferable and each Warrant Certificate shall evidence one or more
Warrants.] Each Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein,
to subscribe for one Warrant Security. [If Other Securities and Warrants —Warrant Certificates will be
issued with the Other Securities and each Warrant Certificate will evidence [●] Warrants for each [$[●] principal
amount] [[●] shares] of Other Securities issued.]

 

1.2            Execution
and Delivery of Warrant Certificates. Each Warrant Certificate, whenever issued, shall be in registered form substantially
in the form set forth in Exhibit A hereto, shall be dated the date of its countersignature by the Warrant Agent and
may have such letters, numbers, or other marks of identification or designation and such legends or endorsements printed, lithographed
or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive evidence
of such approval) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law
or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange on which
the Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf of the Company by any of
its present or future chief executive officers, presidents, senior vice presidents, vice presidents, chief financial officers,
chief legal officers, treasurers, assistant treasurers, controllers, assistant controllers, secretaries or assistant secretaries
under its corporate seal reproduced thereon. Such signatures may be manual or facsimile signatures of such authorized officers
and may be imprinted or otherwise reproduced on the Warrant Certificates. The seal of the Company may be in the form of a facsimile
thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Warrant Certificates.

 

    1

     

    

 

No Warrant Certificate
shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant Certificate has been
countersigned by the manual signature of the Warrant Agent. Such signature by the Warrant Agent upon any Warrant Certificate executed
by the Company shall be conclusive evidence that the Warrant Certificate so countersigned has been duly issued hereunder.

 

In case any officer
of the Company who shall have signed any of the Warrant Certificates either manually or by facsimile signature shall cease to be
such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent, such Warrant
Certificates may be countersigned and delivered notwithstanding that the person who signed such Warrant Certificates ceased to
be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual
date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution
of this Agreement any such person was not such officer.

 

The term “holder”
or “holder of a Warrant Certificate” as used herein shall mean any person in whose name at the time any
Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose.

 

1.3            Issuance
of Warrant Certificates. Warrant Certificates evidencing the right to subscribe for Warrant Securities may be executed by the Company
and delivered to the Warrant Agent upon the execution of this Agreement or from time to time thereafter. The Warrant Agent shall,
upon receipt of Warrant Certificates duly executed on behalf of the Company, countersign such Warrant Certificates and shall deliver
such Warrant Certificates to or upon the order of the Company.

 

Article 2

 

WARRANT
PRICE, DURATION AND EXERCISE OF WARRANTS

 

2.1            Warrant
Price. During the period specified in Section 2.2, each Warrant shall, subject to the terms of this Agreement and the
applicable Warrant Certificate, entitle the holder thereof to subscribe for the number of Warrant Securities specified in the applicable
Warrant Certificate at an exercise price of $[●] per Warrant Security, subject to adjustment upon the occurrence of certain
events, as hereinafter provided. Such subscription for price per Warrant Security is referred to in this Agreement as the “Warrant
Price.”

 

2.2            Duration
of Warrants. Each Warrant may be exercised in whole or in part at any time, as specified herein, on or after [the date thereof]
[●] and at or before [●] p.m., [City] time, on [●] or such later date as the Company may designate by notice
to the Warrant Agent and the holders of Warrant Certificates mailed to their addresses as set forth in the record books of the
Warrant Agent (the “Expiration Date”). Each Warrant not exercised at or before [●] p.m., [City]
time, on the Expiration Date shall become void, and all rights of the holder of the Warrant Certificate evidencing such Warrant
under this Agreement shall cease.

    2

     

    

 

2.3            Exercise
of Warrants.

 

(a)            During
the period specified in Section 2.2, the Warrants may be exercised to subscribe for a whole number of Warrant Securities in registered
form by providing certain information as set forth on the reverse side of the Warrant Certificate and by paying in full, in lawful
money of the United States of America, [in cash or by certified check or official bank check in New York Clearing House funds]
[by bank wire transfer in immediately available funds] the Warrant Price for each Warrant Security with respect to which a Warrant
is being exercised to the Warrant Agent at its corporate trust office, provided that such exercise is subject to receipt within
five business days of such payment by the Warrant Agent of the Warrant Certificate with the form of election to subscribe for Warrant
Securities set forth on the reverse side of the Warrant Certificate properly completed and duly executed. The date on which payment
in full of the Warrant Price is received by the Warrant Agent shall, subject to receipt of the Warrant Certificate as aforesaid,
be deemed to be the date on which the Warrant is exercised; provided, however, that if, at the date of receipt of such Warrant
Certificates and payment in full of the Warrant Price, the transfer books for the Warrant Securities purchasable upon the exercise
of such Warrants shall be closed, no such receipt of such Warrant Certificates and no such payment of such Warrant Price shall
be effective to constitute the person so designated to be named as the holder of record of such Warrant Securities on such date,
but shall be effective to constitute such person as the holder of record of such Warrant Securities for all purposes at the opening
of business on the next succeeding day on which the transfer books for the Warrant Securities purchasable upon the exercise of
such Warrants shall be opened, and the certificates for the Warrant Securities in respect of which such Warrants are then exercised
shall be issuable as of the date on such next succeeding day on which the transfer books shall next be opened, and until such date
the Company shall be under no duty to deliver any certificate for such Warrant Securities. The Warrant Agent shall deposit all
funds received by it in payment of the Warrant Price in an account of the Company maintained with it and shall advise the Company
by telephone at the end of each day on which a payment for the exercise of Warrants is received of the amount so deposited to its
account. The Warrant Agent shall promptly confirm such telephone advice to the Company in writing.

 

(b)            The
Warrant Agent shall, from time to time, as promptly as practicable, advise the Company of (i) the number of Warrant Securities
with respect to which Warrants were exercised, (ii) the instructions of each holder of the Warrant Certificates evidencing
such Warrants with respect to delivery of the Warrant Securities to which such holder is entitled upon such exercise, (iii) delivery
of Warrant Certificates evidencing the balance, if any, of the Warrants for the remaining Warrant Securities after such exercise,
and (iv) such other information as the Company shall reasonably require.

 

(c)            The Company shall not be required to pay any stamp duty, stamp duty reserve tax, issuance, transfer, registration tax or other
tax, duty, fee or other governmental charge, including any penalty or interest in respect thereof (a “Transfer Tax”)
arising in relation to any transfer, issue or other delivery of the Warrant Securities, and in the event that any such transfer,
issue or other delivery is involved, the Company shall not be required to transfer, issue or otherwise deliver any Warrant
Security until such Transfer Tax shall have been paid or it has been established to the Company's satisfaction that no such
Transfer Tax is due or may arise.

 

(d)            The
Company shall not be required to pay any stamp or other tax or other governmental charge required to be paid in connection with
any transfer involved in the issue of the Warrant Securities, and in the event that any such transfer is involved, the Company
shall not be required to issue or deliver any Warrant Security until such tax or other charge shall have been paid or it has been
established to the Company’s satisfaction that no such tax or other charge is due.

 

(e)            Prior to the issuance of any Warrants pursuant to this Agreement, and at all times through the Expiration Date the Company
shall ensure that the Directors have sufficient authority and power under section 551 and (if applicable) section 570 of the
UK Companies Act 2006 to issue such Warrants.

Article 3

 

OTHER
PROVISIONS RELATING TO RIGHTS OF HOLDERS OF

WARRANT CERTIFICATES

 

3.1            No
Rights as Warrant Securityholder Conferred by Warrants or Warrant Certificates. No Warrant Certificate or Warrant evidenced
thereby shall entitle the holder thereof to any of the rights of a holder of Warrant Securities, including, without limitation,
the right to receive the payment of dividends or distributions, if any, on the Warrant Securities or to exercise any voting rights,
except to the extent expressly set forth in this Agreement or the applicable Warrant Certificate.

 

3.2            Lost,
Stolen, Mutilated or Destroyed Warrant Certificates. Upon receipt by the Warrant Agent of evidence reasonably satisfactory
to it and the Company of the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate and/or indemnity
reasonably satisfactory to the Warrant Agent and the Company and, in the case of mutilation, upon surrender of the mutilated Warrant
Certificate to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant Agent that such
Warrant Certificate has been acquired by a bona fide purchaser, the Company shall execute, and an authorized officer of the Warrant
Agent shall manually countersign and deliver, in exchange for or in lieu of the lost, stolen, destroyed or mutilated Warrant Certificate,
a new Warrant Certificate of the same tenor and evidencing Warrants for a like number of Warrant Securities. Upon the issuance
of any new Warrant Certificate under this Section 3.2, the Company may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses
of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant to this Section 3.2
in lieu of any lost, stolen or destroyed Warrant Certificate shall represent an additional contractual obligation of the Company,
whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by anyone, and shall be entitled
to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates duly executed and delivered
hereunder. The provisions of this Section 3.2 are exclusive and shall preclude (to the extent lawful) all other rights and
remedies with respect to the replacement of mutilated, lost, stolen or destroyed Warrant Certificates.

 

3.3            Holder
of Warrant Certificate May Enforce Rights. Notwithstanding any of the provisions of this Agreement, any holder of a Warrant
Certificate, without the consent of the Warrant Agent, the holder of any Warrant Securities or the holder of any other Warrant
Certificate, may, in such holder’s own behalf and for such holder’s own benefit, enforce, and may institute and maintain
any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such holder’s right to
exercise the Warrants evidenced by such holder’s Warrant Certificate in the manner provided in such holder’s Warrant
Certificate and in this Agreement.

 

3.4            Adjustments.

 

(a)            In
case the Company shall at any time subdivide its issued shares of [title of Preference Share purchasable through exercise of
Warrants] into a greater number of shares, the Warrant Price in effect immediately prior to such subdivision shall be
proportionately reduced and the number of Warrant Securities purchasable under the Warrants shall be proportionately
increased. Conversely, in case the outstanding shares of [title of Preference Share purchasable through exercise of Warrants]
shall be consolidated into a smaller number of shares, the Warrant Price in effect immediately prior to such consolidated
shall be proportionately increased and the number of Warrant Securities purchasable under the Warrants shall be
proportionately decreased.

 

(b)            If
at any time or from time to time the holders of [title of Preference Share purchasable through exercise of Warrants] (or any shares
of stock or other securities at the time receivable upon the exercise of the Warrants) shall have received or become entitled to
receive, without payment therefore,

 

    4

     

    

 

(i)            [title
of Preference Share purchasable through exercise of Warrants] or any shares of stock or other securities which are at any time
directly or indirectly convertible into or exchangeable for [title of Preference Share purchasable through exercise of Warrants],
or any rights or options to subscribe for, purchase or otherwise acquire any of the foregoing by way of dividend or other distribution;

 

(ii)            any
cash paid or payable otherwise than in accordance with the terms of [title of Preference Share purchasable through exercise of
Warrants] or as a cash dividend paid or payable out of the Company’s realized profits;

 

(iii)            any
evidence of the Company’s indebtedness or rights to subscribe for or purchase the Company’s indebtedness; or

 

(iv)            [title
of Preference Share purchasable through exercise of Warrants] or additional shares or other securities or property (including cash)
by way of spinoff, split-up, reclassification, consolidation of shares or similar corporate rearrangement (other than shares of [title
of Preference Share purchasable through exercise of Warrants] issued as a subdivision or adjustments in respect of which shall
be covered by the terms of Section 3.4(a) above), then and in each such case, the holder of each Warrant shall, upon
the exercise of the Warrant, be entitled to receive, in addition to the number of Warrant Securities receivable thereupon, and
without payment of any additional consideration therefore, the amount of stock and other securities and property (including cash
and indebtedness or rights to subscribe for or purchase indebtedness) which such holder would hold on the date of such exercise
had such holder been the holder of record of such Warrant Securities as of the date on which holders of [title of Preference Share
purchasable through exercise of Warrants] received or became entitled to receive such shares or all other additional stock and
other securities and property.

 

(c)            In
case of (i) any reclassification, capital reorganization, or change in the [title of Preference Share purchasable
through exercise of Warrants] of the Company (other than as a result of a subdivision, combination, or stock dividend
provided for in Section 3.4(a) or Section 3.4(b) above), (ii) share exchange, merger or similar
transaction of the Company with or into another person or entity (other than a share exchange, merger or similar transaction
in which the Company is the acquiring or surviving corporation and which does not result in any change in the [title of
Preference Share purchasable through exercise of Warrants] other than the issuance of additional shares of [title of
Preference Share purchasable through exercise of Warrants]) or (iii) the sale, exchange, lease, transfer or other
disposition of all or substantially all of the properties and assets of the Company as an entirety (in any such case, a
 “Reorganization Event”), then, as a condition of such Reorganization Event, to the extent permitted
by applicable law and regulation, provisions shall be made, and duly executed documents evidencing the same from the Company
or its successor shall be delivered to the holders of the Warrants, so that the holders of the Warrants shall have the right
at any time prior to the expiration of the Warrants to subscribe for or purchase, at a total price equal to that payable upon
the exercise of the Warrants, the kind and amount of shares of stock and other securities and property receivable in
connection with such Reorganization Event by a holder of the same number of shares of [title of Preference Share purchasable
through exercise of Warrants] as were purchasable by the holders of the Warrants immediately prior to such Reorganization
Event. In any such case appropriate provisions shall be made with respect to the rights and interests of the holders of the
Warrants so that the provisions hereof shall thereafter be applicable with respect to any shares of stock or other securities
and property deliverable upon exercise the Warrants, and appropriate adjustments shall be made to the Warrant Price payable
hereunder provided the aggregate subscription price shall remain the same. In the case of any transaction described in clauses
(ii) and (iii) above, the Company shall thereupon be relieved of any further obligation hereunder or under the
Warrants, and the Company as the predecessor corporation may thereupon or at any time thereafter be dissolved, wound up or
liquidated. Such successor or assuming entity thereupon may cause to be signed, and may issue either in its own name or in
the name of the Company, any or all of the Warrants issuable hereunder which heretofore shall not have been signed by the
Company, and may execute and deliver securities in its own name, in fulfillment of its obligations to deliver Warrant
Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the same legal rank and
benefit under this Agreement as the Warrants theretofore or thereafter issued in accordance with the terms of this Agreement
as though all of such Warrants had been issued at the date of the execution hereof. In any case of any such Reorganization
Event, such changes in phraseology and form (but not in substance) may be made in the Warrants thereafter to be issued as may
be appropriate. The Warrant Agent may receive a written opinion of legal counsel as conclusive evidence that any such
Reorganization Event complies with the provisions of this Section 3.4.

 

    5

     

    

 

(d)            The
Company may, at its option, at any time until the Expiration Date, reduce the then current Warrant Price to any amount deemed appropriate
by the Board of Directors of the Company for any period not exceeding twenty consecutive days (as evidenced in a resolution adopted
by such Board of Directors), but only upon giving the notices required by Section 3.5 at least ten days prior to taking such
action.

 

(e)            Except
as herein otherwise expressly provided, no adjustment in the Warrant Price shall be made by reason of the issuance of any
securities of the Company or for any other reason whatsoever.

 

(f)            No
fractional Warrant Securities shall be issued upon the exercise of Warrants. If more than one Warrant shall be exercised at one
time by the same holder, the number of full Warrant Securities which shall be issuable upon such exercise shall be computed on
the basis of the aggregate number of Warrant Securities subscribed for pursuant to the Warrants so exercised. Instead of any fractional
Warrant Security which would otherwise be issuable upon exercise of any Warrant, the Company shall pay a cash adjustment in respect
of such fraction in an amount equal to the same fraction of the last reported sale price (or bid price if there were no sales)
per Warrant Security, in either case as reported on the principal registered national securities exchange on which the Warrant
Securities are listed or admitted to trading on the business day that next precedes the day of exercise or, if the Warrant Securities
are not then listed or admitted to trading on any registered national securities exchange, the average of the closing high bid
and low asked prices as reported on the OTC Bulletin Board Service (the “OTC Bulletin Board”) operated
by the Financial Industry Regulatory Authority, Inc. (“FINRA” ) or, if not available on the OTC
Bulletin Board, then the average of the closing high bid and low asked prices as reported on any other U.S. quotation medium or
inter-dealer quotation system on such date, or if on any such date the Warrant Securities are not listed or admitted to trading
on a registered national securities exchange, are not included in the OTC Bulletin Board, and are not quoted on any other U.S.
quotation medium or inter-dealer quotation system, an amount equal to the same fraction of the average of the closing bid and asked
prices as furnished by any FINRA member firm selected from time to time by the Company for that purpose at the close of business
on the business day that next precedes the day of exercise.

 

(g)            Whenever
the Warrant Price then in effect is adjusted as herein provided, the Company shall mail to each holder of the Warrants at such
holder’s address as it shall appear on the books of the Company a statement setting forth the adjusted Warrant Price then
and thereafter effective under the provisions hereof, together with the facts, in reasonable detail, upon which such adjustment
is based.

 

    6

     

    

 

(h)            Notwithstanding
anything to the contrary herein, in no event shall the Warrant Price, as adjusted in accordance with the terms hereof, be less
than the nominal value per share of [title of Preference Share purchasable through exercise of Warrants].

 

3.5            Notice
to Warrantholders. In case the Company shall (a) effect any dividend or distribution described in Section 3.4(b),
(b) effect any Reorganization Event, (c) make any distribution on or in respect of the [title of Preference Shares purchasable
through exercise of Warrants] in connection with the dissolution, liquidation or winding up of the Company, or (d) reduce
the then current Warrant Price pursuant to Section 3.4(d), then the Company shall mail to each holder of Warrants at such
holder’s address as it shall appear on the books of the Warrant Agent, at least ten days prior to the applicable date hereinafter
specified, a notice stating (x) the record date for such dividend or distribution, or, if a record is not to be taken, the
date as of which the holders of record of [title of Preference Shares purchasable through exercise of Warrants] that will be entitled
to such dividend or distribution are to be determined, (y) the date on which such Reorganization Event, dissolution, liquidation
or winding up is expected to become effective, and the date as of which it is expected that holders of [title of Preference Shares
purchasable through exercise of Warrants] of record shall be entitled to exchange their shares of [title of Preference Shares purchasable
through exercise of Warrants] for securities or other property deliverable upon such Reorganization Event, dissolution, liquidation
or winding up, or (z) the first date on which the then current Warrant Price shall be reduced pursuant to Section 3.4(d).
No failure to mail such notice nor any defect therein or in the mailing thereof shall affect any such transaction or any adjustment
in the Warrant Price required by Section 3.4.

 

3.6            [If
the Warrants are Subject to Acceleration by the Company, Insert — Acceleration of Warrants by the Company.

 

(a)            At
any time on or after [●], the Company shall have the right to accelerate any or all Warrants at any time by causing them
to expire at the close of business on the day next preceding a specified date (the “Acceleration Date”),
if the Market Price (as hereinafter defined) of the [title of Preference Shares purchasable through exercise of Warrants] equals
or exceeds [●] percent ([●]%) of the then effective Warrant Price on any twenty Trading Days (as hereinafter defined)
within a period of thirty consecutive Trading Days ending no more than five Trading Days prior to the date on which the Company
gives notice to the Warrant Agent of its election to accelerate the Warrants.

 

(b)            (b) “Market
Price” for each Trading Day shall be, if the [title of Preference Share purchasable through exercise of Warrants]
is listed or admitted to trading on any registered national securities exchange, the last reported sale price, regular way (or,
if no such price is reported, the average of the reported closing bid and asked prices, regular way) of [title of Preference Share
purchasable through exercise of Warrants], in either case as reported on the principal registered national securities exchange
on which the [title of Preference Share purchasable through exercise of Warrants] is listed or admitted to trading or, if not listed
or admitted to trading on any registered national securities exchange, the average of the closing high bid and low asked prices
as reported on the OTC Bulletin Board operated by FINRA, or if not available on the OTC Bulletin Board, then the average of the
closing high bid and low asked prices as reported on any other U.S. quotation medium or inter-dealer quotation system, or if on
any such date the shares of [title of Preference Share purchasable through exercise of Warrants] are not listed or admitted to
trading on a registered national securities exchange, are not included in the OTC Bulletin Board, and are not quoted on any other
U.S. quotation medium or inter-dealer quotation system, the average of the closing bid and asked prices as furnished by any FINRA
member firm selected from time to time by the Company for that purpose. “Trading Day” shall be each Monday through
Friday, other than any day on which securities are not traded in the system or on the exchange that is the principal market for
the [title of Preference Share purchasable through exercise of Warrants], as determined by the Board of Directors of the Company.
In the event of an acceleration of less than all of the Warrants, the Warrant Agent shall select the Warrants to be accelerated
by lot, pro rata or in such other manner as it deems, in its discretion, to be fair and appropriate.

 

    7

     

    

 

(c)            Notice
of an acceleration specifying the Acceleration Date shall be sent by mail first class, postage prepaid, to each registered holder
of a Warrant Certificate representing a Warrant accelerated at such holder’s address appearing on the books of the Warrant
Agent not more than sixty days nor less than thirty days before the Acceleration Date. Such notice of an acceleration also shall
be given no more than twenty days, and no less than ten days, prior to the mailing of notice to registered holders of Warrants
pursuant to this Section 3.6, by publication at least once in a newspaper of general circulation in the City of New York.

 

(d)            Any
Warrant accelerated may be exercised until [●] p.m., [City] time, on the business day next preceding the Acceleration Date.
The Warrant Price shall be payable as provided in Section 2.]

 

Article 4

 

EXCHANGE
AND TRANSFER OF WARRANT CERTIFICATES

 

4.1            Exchange
and Transfer of Warrant Certificates. Upon surrender at the corporate trust office of the Warrant Agent, Warrant Certificates evidencing
Warrants may be exchanged for Warrant Certificates in other denominations evidencing such Warrants or the transfer thereof may
be registered in whole or in part; provided that such other Warrant Certificates evidence Warrants for the same aggregate number
of Warrant Securities as the Warrant Certificates so surrendered. The Warrant Agent shall keep, at its corporate trust office,
books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates and exchanges
and transfers of outstanding Warrant Certificates, upon surrender of the Warrant Certificates to the Warrant Agent at its corporate
trust office for exchange or registration of transfer, properly endorsed or accompanied by appropriate instruments of registration
of transfer and written instructions for transfer, all in form satisfactory to the Company and the Warrant Agent. No service charge
shall be made for any exchange or registration of transfer of Warrant Certificates, but the Company may require payment of a sum
sufficient to cover any  Transfer Tax that may arise in relation to any such exchange
or registration of transfer. Whenever any Warrant Certificates are so surrendered for exchange or registration of transfer, an
authorized officer of the Warrant Agent shall manually countersign and deliver to the person or persons entitled thereto a Warrant
Certificate or Warrant Certificates duly authorized and executed by the Company, as so requested. The Warrant Agent shall not be
required to effect any exchange or registration of transfer which will result in the issuance of a Warrant Certificate evidencing
a Warrant for a fraction of a Warrant Security or a number of Warrants for a whole number of Warrant Securities and a fraction
of a Warrant Security. All Warrant Certificates issued upon any exchange or registration of transfer of Warrant Certificates shall
be the valid obligations of the Company, evidencing the same obligations and entitled to the same benefits under this Agreement
as the Warrant Certificate surrendered for such exchange or registration of transfer.

 

4.2            Treatment
of Holders of Warrant Certificates. The Company, the Warrant Agent and all other persons may treat the registered holder of
a Warrant Certificate as the absolute owner thereof for any purpose and as the person entitled to exercise the rights represented
by the Warrants evidenced thereby, any notice to the contrary notwithstanding.

 

4.3            Cancellation
of Warrant Certificates. Any Warrant Certificate surrendered for exchange, registration of transfer or exercise of the Warrants
evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant Agent and all Warrant Certificates surrendered
or so delivered to the Warrant Agent shall be promptly canceled by the Warrant Agent and shall not be reissued and, except as expressly
permitted by this Agreement, no Warrant Certificate shall be issued hereunder in exchange therefor or in lieu thereof. The Warrant
Agent shall deliver to the Company from time to time or otherwise dispose of canceled Warrant Certificates in a manner satisfactory
to the Company.

THE WARRANT AGENT

 

5.1            Warrant

upon the terms and subject to the conditions herein set forth, and [●] hereby accepts such appointment. The Warrant Agent

with respect to such powers and authority contained in the Warrant Certificates are subject to and governed by the terms and provisions
hereof.

 

5.2            Conditions
of Warrant Agent’s Obligations. The Warrant Agent accepts its obligations herein set forth upon the terms and conditions
hereof, including the following to all of which the Company agrees and to all of which the rights hereunder of the holders from
time to time of the Warrant Certificates shall be subject:

 

(a)            Compensation
and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation to be agreed upon with the
Company for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket
expenses (including reasonable counsel fees) incurred without negligence, bad faith or willful misconduct by the Warrant
Agent in connection with the services rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the
Warrant Agent for, and to hold it harmless against, any loss, liability or expense incurred without negligence, bad faith or
willful misconduct on the part of the Warrant Agent, arising out of or in connection with its acting as Warrant Agent
hereunder other than any Transfer Tax arising in relation to any Warrant Certificates sold pursuant to this Agreement, including the reasonable costs and expenses of defending against any claim of such liability.

 

(b)            Agent
for the Company. In acting under this Agreement and in connection with the Warrant Certificates, the Warrant Agent is acting
solely as agent of the Company and does not assume any obligations or relationship of agency or trust for or with any of the holders
of Warrant Certificates or beneficial owners of Warrants.

 

(c)            Counsel.
The Warrant Agent may consult with counsel satisfactory to it, which may include counsel for the Company, and the written advice
of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by
it hereunder in good faith and in accordance with the advice of such counsel.

 

(d)            Documents.
The Warrant Agent shall be protected and shall incur no liability for or in respect of any action taken or omitted by it in
reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other paper or document
reasonably believed by it to be genuine and to have been presented or signed by the proper parties.

 

(e)            Certain
Transactions. The Warrant Agent, and its officers, directors and employees, may become the owner of, or acquire any interest
in, Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to the extent permitted
by applicable law, it or they may engage or be interested in any financial or other transaction with the Company and may act on,
or as depositary, trustee or agent for, any committee or body of holders of Warrant Securities or other obligations of the Company
as freely as if it were not the Warrant Agent hereunder. Nothing in this Agreement shall be deemed to prevent the Warrant Agent
from acting as trustee under any indenture to which the Company is a party.

Responsibility for Representations. The Warrant Agent shall not be responsible for any of the recitals or representations herein
or in the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon), all of which are made solely
by the Company.

 

(i)            No
Implied Obligations. The Warrant Agent shall be obligated to perform only such duties as are herein and in the Warrant Certificates
specifically set forth and no implied duties or obligations shall be read into this Agreement or the Warrant Certificates against
the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action hereunder which may tend to involve it
in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured to it. The
Warrant Agent shall not be accountable or under any duty or responsibility for the use by the Company of any of the Warrant Certificates
authenticated by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or for the application by the
Company of the proceeds of the Warrant Certificates. The Warrant Agent shall have no duty or responsibility in case of any default
by the Company in the performance of its covenants or agreements contained herein or in the Warrant Certificates or in the case
of the receipt of any written demand from a holder of a Warrant Certificate with respect to such default, including, without limiting
the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise
or, except as provided in Section 6.2 hereof, to make any demand upon the Company.

 

5.3            Resignation,
Removal and Appointment of Successors.

 

(a)            The
Company agrees, for the benefit of the holders from time to time of the Warrant Certificates, that there shall at all times be
a Warrant Agent hereunder until all the Warrants have been exercised or are no longer exercisable.

 

(b)            The
Warrant Agent may at any time resign as agent by giving written notice to the Company of such intention on its part, specifying
the date on which its desired resignation shall become effective; provided that such date shall not be less than three months after
the date on which such notice is given unless the Company otherwise agrees. The Warrant Agent hereunder may be removed at any time
by the filing with it of an instrument in writing signed by or on behalf of the Company and specifying such removal and the intended
date when it shall become effective. Such resignation or removal shall take effect upon the appointment by the Company, as hereinafter
provided, of a successor Warrant Agent (which shall be a bank or trust company authorized under the laws of the jurisdiction of
its organization to exercise corporate trust powers) and the acceptance of such appointment by such successor Warrant Agent. The
obligation of the Company under Section 5.2(a) shall continue to the extent set forth therein notwithstanding the resignation
or removal of the Warrant Agent.

 

    10

     

    

 

(c)            In
case at any time the Warrant Agent shall resign, or shall be removed, or shall become incapable of acting, or shall be adjudged
a bankrupt or insolvent, or shall commence a voluntary case under the Federal bankruptcy laws, as now or hereafter constituted,
or under any other applicable Federal or state bankruptcy, insolvency or similar law or shall consent to the appointment of or
taking possession by a receiver, custodian, liquidator, assignee, trustee, sequestrator (or other similar official) of the Warrant

of a receiver, custodian, liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant Agent or of its property

of rehabilitation, conservation, winding up or liquidation, a successor Warrant Agent, qualified as aforesaid, shall be appointed
by the Company by an instrument in writing, filed with the successor Warrant Agent. Upon the appointment as aforesaid of a successor
Warrant Agent and acceptance by the successor Warrant Agent of such appointment, the Warrant Agent shall cease to be Warrant Agent
hereunder.

 

(d)            Any
successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its predecessor and to the Company an instrument
accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act, deed or conveyance,
shall become vested with all the authority, rights, powers, trusts, immunities, duties and obligations of such predecessor with
like effect as if originally named as Warrant Agent hereunder, and such predecessor, upon payment of its charges and disbursements
then unpaid, shall thereupon become obligated to transfer, deliver and pay over, and such successor Warrant Agent shall be entitled
to receive, all monies, securities and other property on deposit with or held by such predecessor, as Warrant Agent hereunder.

This
Debt Securities Warrant Agreement (this “Agreement”), dated as of [●], between Bicycle
Therapeutics plc, a public limited company incorporated under the laws of England and Wales (the “Company”),
and [●], a [corporation] [national banking association] organized and existing under the laws of [●] and having a corporate
trust office in [●], as warrant agent (the “Warrant Agent”).

 

Whereas,
the Company has entered into an indenture dated as of [●] (the “Indenture”), with [●], as
trustee (such trustee, and any successors to such trustee, herein called the “Trustee”), providing for
the issuance from time to time of its debt securities, to be issued in one or more series as provided in the Indenture (the “Debt
Securities”);

 

Whereas,
the Company proposes to sell [If Warrants are sold with other securities —[title of such other securities
being offered] (the “Other Securities”) with] warrant certificates evidencing one or more warrants (the
 “Warrants” or, individually, a “Warrant”) representing the right to purchase
[title of Debt Securities purchasable through exercise of Warrants] (the “Warrant Debt Securities”),
such warrant certificates and other warrant certificates issued pursuant to this Agreement being herein called the “Warrant
Certificates”; and

 

Whereas,
the Company desires the Warrant Agent to act on behalf of the Company, and the Warrant Agent is willing so to act, in
connection with the issuance, registration, transfer, exchange, exercise and replacement of the Warrant Certificates, and in this
Agreement wishes to set forth, among other things, the form and provisions of the Warrant Certificates and the terms and conditions
on which they may be issued, registered, transferred, exchanged, exercised and replaced.

 

Now
Therefore, in consideration of the premises and of the mutual agreements herein contained, the parties hereto agree
as follows:

 

Article 1

 

ISSUANCE
OF WARRANTS AND EXECUTION AND

DELIVERY OF WARRANT CERTIFICATES

 

1.1          Issuance
of Warrants. [If Warrants alone — Upon issuance, each Warrant Certificate shall evidence one or more Warrants.]
[If Other Securities and Warrants — Warrant Certificates will be issued in connection with the issuance of
the Other Securities but shall be separately transferable and each Warrant Certificate shall evidence one or more Warrants.] Each
Warrant evidenced thereby shall represent the right, subject to the provisions contained herein and therein, to purchase one Warrant
Debt Security. [If Other Securities and Warrants — Warrant Certificates will be issued with the Other Securities
and each Warrant Certificate will evidence [●] Warrants for each [$[●] principal amount] [[●] shares] of Other
Securities issued.]

 

1.2          Execution
and Delivery of Warrant Certificates. Each Warrant Certificate, whenever issued, shall be in registered form substantially
in the form set forth in Exhibit A hereto, shall be dated the date of its countersignature by the Warrant Agent and
may have such letters, numbers, or other marks of identification or designation and such legends or endorsements printed, lithographed
or engraved thereon as the officers of the Company executing the same may approve (execution thereof to be conclusive evidence
of such approval) and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law
or with any rule or regulation made pursuant thereto or with any rule or regulation of any securities exchange on which
the Warrants may be listed, or to conform to usage. The Warrant Certificates shall be signed on behalf of the Company by any of
its present or future chief executive officers, presidents, senior vice presidents, vice presidents, chief financial officers,
chief legal officers, treasurers, assistant treasurers, controllers, assistant controllers, secretaries or assistant secretaries
under its corporate seal reproduced thereon. Such signatures may be manual or facsimile signatures of such authorized officers

thereof and may be impressed, affixed, imprinted or otherwise reproduced on the Warrant Certificates.

    1

     

    

 

No Warrant Certificate
shall be valid for any purpose, and no Warrant evidenced thereby shall be exercisable, until such Warrant Certificate has been
countersigned by the manual signature of the Warrant Agent. Such signature by the Warrant Agent upon any Warrant Certificate executed
by the Company shall be conclusive evidence that the Warrant Certificate so countersigned has been duly issued hereunder.

 

In case any officer
of the Company who shall have signed any of the Warrant Certificates either manually or by facsimile signature shall cease to be
such officer before the Warrant Certificates so signed shall have been countersigned and delivered by the Warrant Agent, such Warrant
Certificates may be countersigned and delivered notwithstanding that the person who signed such Warrant Certificates ceased to
be such officer of the Company; and any Warrant Certificate may be signed on behalf of the Company by such persons as, at the actual
date of the execution of such Warrant Certificate, shall be the proper officers of the Company, although at the date of the execution
of this Agreement any such person was not such officer.

 

The term “holder”
or “holder of a Warrant Certificate” as used herein shall mean any person in whose name at the time any
Warrant Certificate shall be registered upon the books to be maintained by the Warrant Agent for that purpose.

 

1.3          Issuance
of Warrant Certificates. Warrant Certificates evidencing the right to purchase Warrant Debt Securities may be executed by the
Company and delivered to the Warrant Agent upon the execution of this Agreement or from time to time thereafter. The Warrant Agent
shall, upon receipt of Warrant Certificates duly executed on behalf of the Company, countersign such Warrant Certificates and shall
deliver such Warrant Certificates to or upon the order of the Company.

 

Article 2

 

WARRANT
PRICE, DURATION AND EXERCISE OF WARRANTS

 

2.1          Warrant
Price. During the period specified in Section 2.2, each Warrant shall, subject to the terms of this Agreement and the
applicable Warrant Certificate, entitle the holder thereof to purchase the principal amount of Warrant Debt Securities specified
in the applicable Warrant Certificate at an exercise price of [●]% of the principal amount thereof [plus accrued amortization,
if any, of the original issue discount of the Warrant Debt Securities] [plus accrued interest, if any, from the most recent date
from which interest shall have been paid on the Warrant Debt Securities or, if no interest shall have been paid on the Warrant
Debt Securities, from the date of their initial issuance.] [The original issue discount ($[●] for each $1,000 principal amount
of Warrant Debt Securities) will be amortized at a [●]% annual rate, computed on a[n] [semi-] annual basis [using a 360-day
year consisting of twelve 30-day months].] Such purchase price for the Warrant Debt Securities is referred to in this Agreement
as the “Warrant Price.

 

2.2          Duration
of Warrants. Each Warrant may be exercised in whole or in part at any time, as specified herein, on or after [the date thereof]
[●] and at or before [●] p.m., [City] time, on [●] or such later date as the Company may designate by notice
to the Warrant Agent and the holders of Warrant Certificates mailed to their addresses as set forth in the record books of the
Warrant Agent (the “Expiration Date”). Each Warrant not exercised at or before [●] p.m., [City]

under this Agreement shall cease.

    2

     

    

 

2.3          Exercise
of Warrants.

 

(a)            During
the period specified in Section 2.2, the Warrants may be exercised to purchase a whole number of Warrant Debt Securities in
registered form by providing certain information as set forth on the reverse side of the Warrant Certificate and by paying in full,
in lawful money of the United States of America, [in cash or by certified check or official bank check in New York Clearing House
funds] [by bank wire transfer in immediately available funds] the Warrant Price for each Warrant Debt Security with respect to
which a Warrant is being exercised to the Warrant Agent at its corporate trust office, provided that such exercise is subject to
receipt within five business days of such payment by the Warrant Agent of the Warrant Certificate with the form of election to
purchase Warrant Debt Securities set forth on the reverse side of the Warrant Certificate properly completed and duly executed.
The date on which payment in full of the Warrant Price is received by the Warrant Agent shall, subject to receipt of the Warrant
Certificate as aforesaid, be deemed to be the date on which the Warrant is exercised; provided, however, that if, at the date of
receipt of such Warrant Certificates and payment in full of the Warrant Price, the transfer books for the Warrant Debt Securities
purchasable upon the exercise of such Warrants shall be closed, no such receipt of such Warrant Certificates and no such payment
of such Warrant Price shall be effective to constitute the person so designated to be named as the holder of record of such Warrant
Debt Securities on such date, but shall be effective to constitute such person as the holder of record of such Warrant Debt Securities
for all purposes at the opening of business on the next succeeding day on which the transfer books for the Warrant Debt Securities
purchasable upon the exercise of such Warrants shall be opened, and the certificates for the Warrant Debt Securities in respect
of which such Warrants are then exercised shall be issuable as of the date on such next succeeding day on which the transfer books
shall next be opened, and until such date the Company shall be under no duty to deliver any certificate for such Warrant Debt Securities.
The Warrant Agent shall deposit all funds received by it in payment of the Warrant Price in an account of the Company maintained
with it and shall advise the Company by telephone at the end of each day on which a payment for the exercise of Warrants is received
of the amount so deposited to its account. The Warrant Agent shall promptly confirm such telephone advice to the Company in writing.

 

(b)            The
Warrant Agent shall, from time to time, as promptly as practicable, advise the Company of (i) the number of Warrant Debt Securities
with respect to which Warrants were exercised, (ii) the instructions of each holder of the Warrant Certificates evidencing
such Warrants with respect to delivery of the Warrant Debt Securities to which such holder is entitled upon such exercise, (iii) delivery
of Warrant Certificates evidencing the balance, if any, of the Warrants for the remaining Warrant Debt Securities after such exercise,

holder is entitled, in fully registered form, registered in such name or names as may be directed by such holder. If fewer than
all of the Warrants evidenced by such Warrant Certificate are exercised, the Company shall execute, and an authorized officer of
the Warrant Agent shall manually countersign and deliver, a new Warrant Certificate evidencing Warrants for the number of Warrant
Debt Securities remaining unexercised.

duty, fee or other governmental charge, including any penalty or interest in respect thereof (a “Transfer Tax”)
arising in relation to any transfer, issue or other delivery of the Warrant Debt Securities, and in the event that any such transfer,
issue or delivery is involved, the Company shall not be required to transfer, issue or otherwise deliver any Warrant Debt Securities
until such Transfer Taxshall have been paid or it has been established to the Company's satisfaction that no such Transfer Tax
is due or may arise.

to the issuance of any Warrants exercisable for Debt Securities convertible into Ordinary Shares pursuant to this Agreement, and
at all times through the Expiration Date, the Company shall ensure that the Directors have sufficient authority and power under

Article 3

 

OTHER
PROVISIONS RELATING TO RIGHTS OF HOLDERS OF

WARRANT CERTIFICATES

 

3.1          No
Rights as Holder of Warrant Debt Securities Conferred by Warrants or Warrant Certificates. No Warrant Certificate or Warrant
evidenced thereby shall entitle the holder thereof to any of the rights of a holder of Warrant Debt Securities, including, without
limitation, the right to receive the payment of principal of (or premium, if any) or interest, if any, on the Warrant Debt Securities
or to enforce any of the covenants in the Indenture.

 

3.2          Lost,
Stolen, Mutilated or Destroyed Warrant Certificates. Upon receipt by the Warrant Agent of evidence reasonably satisfactory
to it and the Company of the ownership of and the loss, theft, destruction or mutilation of any Warrant Certificate and/or indemnity
reasonably satisfactory to the Warrant Agent and the Company and, in the case of mutilation, upon surrender of the mutilated Warrant
Certificate to the Warrant Agent for cancellation, then, in the absence of notice to the Company or the Warrant Agent that such
Warrant Certificate has been acquired by a bona fide purchaser, the Company shall execute, and an authorized officer of the Warrant
Agent shall manually countersign and deliver, in exchange for or in lieu of the lost, stolen, destroyed or mutilated Warrant Certificate,
a new Warrant Certificate of the same tenor and evidencing Warrants for a like principal amount of Warrant Debt Securities. Upon
the issuance of any new Warrant Certificate under this Section 3.2, the Company may require the payment of a sum sufficient
to cover any Transfer Tax that may arise in relation thereto and any other expenses (including the fees
and expenses of the Warrant Agent) in connection therewith. Every substitute Warrant Certificate executed and delivered pursuant
to this Section 3.2 in lieu of any lost, stolen or destroyed Warrant Certificate shall represent an additional contractual
obligation of the Company, whether or not the lost, stolen or destroyed Warrant Certificate shall be at any time enforceable by
anyone, and shall be entitled to the benefits of this Agreement equally and proportionately with any and all other Warrant Certificates
duly executed and delivered hereunder. The provisions of this Section 3.2 are exclusive and shall preclude (to the extent
lawful) all other rights and remedies with respect to the replacement of mutilated, lost, stolen or destroyed Warrant Certificates.

 

3.3          Holder
of Warrant Certificate May Enforce Rights. Notwithstanding any of the provisions of this Agreement, any holder of a Warrant
Certificate, without the consent of the Warrant Agent, , the Trustee, the holder of any Warrant Debt Securities or the holder of
any other Warrant Certificate, may, in such holder’s own behalf and for such holder’s own benefit, enforce, and may
institute and maintain any suit, action or proceeding against the Company suitable to enforce, or otherwise in respect of, such
holder’s right to exercise the Warrants evidenced by such holder’s Warrant Certificate in the manner provided in such
holder’s Warrant Certificates and in this Agreement.

    4

     

    

 

3.4          Merger,
Sale, Conveyance or Lease. In case of (a) any share exchange, merger or similar transaction of the Company with or into
another person or entity (other than a share exchange, merger or similar transaction in which the Company is the acquiring or surviving
corporation) or (b) the sale, exchange, lease, transfer or other disposition of all or substantially all of the properties
and assets of the Company as an entirety (in any such case, a “Reorganization Event”), then, as a condition
of such Reorganization Event, to the extent permitted by applicable law and regulation, provisions shall be made, and duly executed documents evidencing the same from the Company’s
successor shall be delivered to the holders of the Warrants, so that such successor shall succeed to and be substituted for the
Company, and assume all the Company’s obligations under, this Agreement and the Warrants. The Company shall thereupon be
relieved of any further obligation hereunder or under the Warrants, and the Company as the predecessor corporation may thereupon
or at any time thereafter be dissolved, wound up or liquidated. Such successor or assuming entity thereupon may cause to be signed,
and may issue either in its own name or in the name of the Company, any or all of the Warrants issuable hereunder which heretofore
shall not have been signed by the Company, and may execute and deliver securities in its own name, in fulfillment of its obligations
to deliver Warrant Debt Securities upon exercise of the Warrants. All the Warrants so issued shall in all respects have the same
legal rank and benefit under this Agreement as the Warrants theretofore or thereafter issued in accordance with the terms of this
Agreement as though all of such Warrants had been issued at the date of the execution hereof. In any case of any such Reorganization
Event, such changes in phraseology and form (but not in substance) may be made in the Warrants thereafter to be issued as may be
appropriate. The Warrant Agent may receive a written opinion of legal counsel as conclusive evidence that any such Reorganization
Event complies with the provisions of this Section 3.4.

 

3.5          Notice
to Warrantholders. In case the Company shall (a) effect any Reorganization Event or (b) make any distribution on
or in respect of the [title of Warrant Debt Securities] in connection with the dissolution, liquidation or winding up of the Company,
then the Company shall mail to each holder of Warrants at such holder’s address as it shall appear on the books of the Warrant
Agent, at least ten days prior to the applicable date hereinafter specified, a notice stating the date on which such Reorganization
Event, dissolution, liquidation or winding up is expected to become effective, and the date as of which it is expected that holders
of [title of Warrant Debt Securities] of record shall be entitled to exchange their shares of [title of Warrant Debt Securities]
for securities or other property deliverable upon such Reorganization Event, dissolution, liquidation or winding up. No failure
to mail such notice nor any defect therein or in the mailing thereof shall affect any such transaction.

 

Article 4

 

EXCHANGE
AND TRANSFER OF WARRANT CERTIFICATES

 

4.1            Exchange
and Transfer of Warrant Certificates. Upon surrender at the corporate trust office of the Warrant Agent, Warrant Certificates evidencing
Warrants may be exchanged for Warrant Certificates in other denominations evidencing such Warrants or the transfer thereof may
be registered in whole or in part; provided that such other Warrant Certificates evidence Warrants for the same aggregate principal
amount of Warrant Debt Securities as the Warrant Certificates so surrendered. The Warrant Agent shall keep, at its corporate trust
office, books in which, subject to such reasonable regulations as it may prescribe, it shall register Warrant Certificates and
exchanges and transfers of outstanding Warrant Certificates, upon surrender of the Warrant Certificates to the Warrant Agent at
its corporate trust office for exchange or registration of transfer, properly endorsed or accompanied by appropriate instruments
of registration of transfer and written instructions for transfer, all in form satisfactory to the Company and the Warrant Agent.
No service charge shall be made for any exchange or registration of transfer of Warrant Certificates, but the Company may require
payment of a sum sufficient to cover any stamp or other tax or other governmental charge that may be imposed in connection with
any such exchange or registration of transfer. Whenever any Warrant Certificates are so surrendered for exchange or registration
of transfer, an authorized officer of the Warrant Agent shall manually countersign and deliver to the person or persons entitled
thereto a Warrant Certificate or Warrant Certificates duly authorized and executed by the Company, as so requested. The Warrant
Agent shall not be required to effect any exchange or registration of transfer which will result in the issuance of a Warrant Certificate
evidencing a Warrant for a fraction of a Warrant Debt Security or a number of Warrants for a whole number of Warrant Debt Securities
and a fraction of a Warrant Debt Security. All Warrant Certificates issued upon any exchange or registration of transfer of Warrant
Certificates shall be the valid obligations of the Company, evidencing the same obligations and entitled to the same benefits under
this Agreement as the Warrant Certificate surrendered for such exchange or registration of transfer.

    5

     

    

 

4.2          Treatment
of Holders of Warrant Certificates. The Company, the Warrant Agent and all other persons may treat the registered holder of
a Warrant Certificate as the absolute owner thereof for any purpose and as the person entitled to exercise the rights represented
by the Warrants evidenced thereby, any notice to the contrary notwithstanding.

 

4.3          Cancellation
of Warrant Certificates. Any Warrant Certificate surrendered for exchange, registration of transfer or exercise of the Warrants
evidenced thereby shall, if surrendered to the Company, be delivered to the Warrant Agent and all Warrant Certificates surrendered
or so delivered to the Warrant Agent shall be promptly canceled by the Warrant Agent and shall not be reissued and, except as expressly
permitted by this Agreement, no Warrant Certificate shall be issued hereunder in exchange therefor or in lieu thereof. The Warrant
Agent shall deliver to the Company from time to time or otherwise dispose of canceled Warrant Certificates in a manner satisfactory
to the Company.

upon the terms and subject to the conditions herein set forth, and [●] hereby accepts such appointment. The Warrant Agent
shall have the powers and authority granted to and conferred upon it in the Warrant Certificates and hereby and such further powers
and authority to act on behalf of the Company as the Company may hereafter grant to or confer upon it. All of the terms and provisions
with respect to such powers and authority contained in the Warrant Certificates are subject to and governed by the terms and provisions
hereof.

of Warrant Agent’s Obligations. The Warrant Agent accepts its obligations herein set forth upon the terms and conditions
hereof, including the following to all of which the Company agrees and to all of which the rights hereunder of the holders from
time to time of the Warrant Certificates shall be subject:

 

(a)            Compensation
and Indemnification. The Company agrees promptly to pay the Warrant Agent the compensation to be agreed upon with the Company
for all services rendered by the Warrant Agent and to reimburse the Warrant Agent for reasonable out-of-pocket expenses (including
reasonable counsel fees) incurred without negligence, bad faith or willful misconduct by the Warrant Agent in connection with the
services rendered hereunder by the Warrant Agent. The Company also agrees to indemnify the Warrant Agent for, and to hold it harmless
against, any loss, liability or expense incurred without negligence, bad faith or willful misconduct on the part of the Warrant
Agent, arising out of or in connection with its acting as Warrant Agent hereunder, other than any Transfer Tax arising in relation to any Warrant Certificates sold pursuant to this Agreement, including the reasonable costs and expenses
of defending against any claim of such liability.

 

(b)            Agent
for the Company. In acting under this Agreement and in connection with the Warrant Certificates, the Warrant Agent is acting
solely as agent of the Company and does not assume any obligations or relationship of agency or trust for or with any of the holders
of Warrant Certificates or beneficial owners of Warrants.

    6

     

    

  

(c)            Counsel.
The Warrant Agent may consult with counsel satisfactory to it, which may include counsel for the Company, and the written advice
of such counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by
it hereunder in good faith and in accordance with the advice of such counsel.

 

(d)            Documents.
The Warrant Agent shall be protected and shall incur no liability for or in respect of any action taken or omitted by it in
reliance upon any Warrant Certificate, notice, direction, consent, certificate, affidavit, statement or other paper or document
reasonably believed by it to be genuine and to have been presented or signed by the proper parties.

 

(e)            Certain
Transactions. The Warrant Agent, and its officers, directors and employees, may become the owner of, or acquire any interest
in, Warrants, with the same rights that it or they would have if it were not the Warrant Agent hereunder, and, to the extent permitted
by applicable law, it or they may engage or be interested in any financial or other transaction with the Company and may act on,
or as depositary, trustee or agent for, any committee or body of holders of Warrant Debt Securities or other obligations of the
Company as freely as if it were not the Warrant Agent hereunder. Nothing in this Agreement shall be deemed to prevent the Warrant
Agent from acting as trustee under any indenture to which the Company is a party, including, without limitation, as Trustee under
the Indenture.

 

(f)            No
Liability for Interest. Unless otherwise agreed with the Company, the Warrant Agent shall have no liability for interest on
any monies at any time received by it pursuant to any of the provisions of this Agreement or of the Warrant Certificates.

 

(g)            No
Liability for Invalidity. The Warrant Agent shall have no liability with respect to any invalidity of this Agreement or any
of the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon).

 

(h)            No
Responsibility for Representations. The Warrant Agent shall not be responsible for any of the recitals or representations herein
or in the Warrant Certificates (except as to the Warrant Agent’s countersignature thereon), all of which are made solely
by the Company.

 

(i)            No
Implied Obligations. The Warrant Agent shall be obligated to perform only such duties as are herein and in the Warrant Certificates
specifically set forth and no implied duties or obligations shall be read into this Agreement or the Warrant Certificates against
the Warrant Agent. The Warrant Agent shall not be under any obligation to take any action hereunder which may tend to involve it
in any expense or liability, the payment of which within a reasonable time is not, in its reasonable opinion, assured to it. The
Warrant Agent shall not be accountable or under any duty or responsibility for the use by the Company of any of the Warrant Certificates
authenticated by the Warrant Agent and delivered by it to the Company pursuant to this Agreement or for the application by the
Company of the proceeds of the Warrant Certificates. The Warrant Agent shall have no duty or responsibility in case of any default
by the Company in the performance of its covenants or agreements contained herein or in the Warrant Certificates or in the case
of the receipt of any written demand from a holder of a Warrant Certificate with respect to such default, including, without limiting
the generality of the foregoing, any duty or responsibility to initiate or attempt to initiate any proceedings at law or otherwise
or, except as provided in Section 6.2 hereof, to make any demand upon the Company.

    7

     

    

 

5.3          Resignation,
Removal and Appointment of Successors.

 

(a)            The
Company agrees, for the benefit of the holders from time to time of the Warrant Certificates, that there shall at all times be
a Warrant Agent hereunder until all the Warrants have been exercised or are no longer exercisable.

 

(b)            The
Warrant Agent may at any time resign as agent by giving written notice to the Company of such intention on its part, specifying
the date on which its desired resignation shall become effective; provided that such date shall not be less than three months after
the date on which such notice is given unless the Company otherwise agrees. The Warrant Agent hereunder may be removed at any time
by the filing with it of an instrument in writing signed by or on behalf of the Company and specifying such removal and the intended
date when it shall become effective. Such resignation or removal shall take effect upon the appointment by the Company, as hereinafter
provided, of a successor Warrant Agent (which shall be a bank or trust company authorized under the laws of the jurisdiction of
its organization to exercise corporate trust powers) and the acceptance of such appointment by such successor Warrant Agent. The
obligation of the Company under Section 5.2(a) shall continue to the extent set forth therein notwithstanding the resignation
or removal of the Warrant Agent.

 

(c)            In
case at any time the Warrant Agent shall resign, or shall be removed, or shall become incapable of acting, or shall be adjudged
a bankrupt or insolvent, or shall commence a voluntary case under the Federal bankruptcy laws, as now or hereafter constituted,
or under any other applicable Federal or state bankruptcy, insolvency or similar law or shall consent to the appointment of or

order for relief by a court having jurisdiction in the premises shall have been entered in respect of the Warrant Agent in an involuntary
case under the Federal bankruptcy laws, as now or hereafter constituted, or any other applicable Federal or state bankruptcy, insolvency
or similar law, or a decree or order by a court having jurisdiction in the premises shall have been entered for the appointment
of a receiver, custodian, liquidator, assignee, trustee, sequestrator (or similar official) of the Warrant Agent or of its property
or affairs, or any public officer shall take charge or control of the Warrant Agent or of its property or affairs for the purpose
of rehabilitation, conservation, winding up or liquidation, a successor Warrant Agent, qualified as aforesaid, shall be appointed
by the Company by an instrument in writing, filed with the successor Warrant Agent. Upon the appointment as aforesaid of a successor
Warrant Agent and acceptance by the successor Warrant Agent of such appointment, the Warrant Agent shall cease to be Warrant Agent
hereunder.

 

(d)            Any
successor Warrant Agent appointed hereunder shall execute, acknowledge and deliver to its predecessor and to the Company an instrument
accepting such appointment hereunder, and thereupon such successor Warrant Agent, without any further act, deed or conveyance,
shall become vested with all the authority, rights, powers, trusts, immunities, duties and obligations of such predecessor with
like effect as if originally named as Warrant Agent hereunder, and such predecessor, upon payment of its charges and disbursements
then unpaid, shall thereupon become obligated to transfer, deliver and pay over, and such successor Warrant Agent shall be entitled
to receive, all monies, securities and other property on deposit with or held by such predecessor, as Warrant Agent hereunder.

corporation into which the Warrant Agent hereunder may be merged or converted or any corporation with which the Warrant Agent may
be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Warrant Agent shall be
a party, or any corporation to which the Warrant Agent shall sell or otherwise transfer all or substantially all the assets and
business of the Warrant Agent, provided that it shall be qualified as aforesaid, shall be the successor Warrant Agent under this
Agreement without the execution or filing of any paper or any further act on the part of any of the parties hereto.

discount of the Warrant Debt Securities] [plus accrued interest, if any, from the most recent date from which interest shall have
been paid on the Warrant Debt Securities or, if no interest shall have been paid on the Warrant Debt Securities, from the date
of their original issuance]. [The original issue discount ($[●] for each $1,000 principal amount of Warrant Debt Securities)
will be amortized at a [●]% annual rate, computed on a[n] [semi-]annual basis [using a 360-day year consisting of twelve
30-day months]. The Holder may exercise the Warrants evidenced hereby by providing certain information set forth on the back hereof

contained in the Warrant Debt Securities and in the Indenture. Copies of the Indenture, including the form of the Warrant Debt

After countersignature by the Warrant Agent
and prior to the expiration of this Warrant Certificate, this Warrant Certificate may be exchanged at the corporate trust office
of the Warrant Agent for Warrant Certificates representing Warrants for the same aggregate principal amount of Warrant Debt Securities.

 

This Warrant Certificate shall not entitle
the Holder hereof to any of the rights of a holder of the Warrant Debt Securities, including, without limitation, the right to
receive payments of principal of (and premium, if any) or interest, if any, on the Warrant Debt Securities or to enforce any of
the covenants of the Indenture.

 

Reference is hereby made to the further
provisions of this Warrant Certificate set forth on the reverse hereof, which further provisions shall for all purposes have the
same effect as if set forth at this place.

 

This Warrant Certificate shall not be valid
or obligatory for any purpose until countersigned by the Warrant Agent.
