AUTOLUS THERAPEUTICS PLC, a company incorporated in England and Wales with number 11185179 whose registered office is at The MediaWorks, 191 Wood Lane, London W12 7FP, United Kingdom (the “Company”).

The Company, by resolution of its Directors, has agreed to issue this certain warrant (the “Warrant”) to purchase American Depositary Shares (“ADSs”) representing ordinary shares in the capital of the Company (“Ordinary Shares”), on the terms and conditions set forth below in this instrument.

Pre-emption rights under section 561 of the UK Companies Act 2006 (the “Companies Act”) have been validly disapplied in relation to the number of Ordinary Shares in the Company to be issued pursuant to this Warrant under the current articles of association of the Company adopted on 26 June 2018 (the “Articles”) .

Pursuant to the terms of the Collaboration and Financing Agreement (the “Collaboration Agreement”) by and between the Company and BXLS V – Autobahn L.P. (“Blackstone”), Blackstone, or its permitted assigns, has agreed to provide up to U.S.$24,000,000 to the Company, to help fund the continued development of certain of the Company’s product candidates in exchange for the Company issuing a warrant to purchase ADSs representing Ordinary Shares to Blackstone.

This instrument has been executed by the Company in favour of the Warrantholder (as defined below). If any term or provision of this Warrant conflicts with any term or provision of the Collaboration Agreement, the terms and provisions of this instrument and the Warrant shall control.

DEFINITIONS AND INTERPRETATION

headings are used for convenience only and shall be ignored in interpreting this instrument;

reference to a clause or schedule is a reference to a clause of, or schedule to, this instrument;

reference to (or to any specific provision of) this instrument or any other document or instrument shall be construed as a reference to this instrument, that provision or that document or instrument as in force for the time being and as amended from time to time in accordance with its terms and Clause 8.1, as applicable;

reference to any gender includes all genders, references to the singular includes the plural (and vice versa) and reference to persons includes bodies corporate, unincorporated associations and partnerships (whether or not any of the same have a separate legal personality);

Unless otherwise specifically provided, where any notice, resolution or document is required by this instrument to be signed by any person, the reproduction of the signature of such person by fax or email (whether in .pdf format or otherwise) shall suffice, provided that confirmation by first class letter is dispatched by close of business on the next following Business Day, in which case the effective notice, resolution or document shall be that sent by fax or email (served in accordance with paragraphs 11 and 12 of Schedule 2), not the confirmatory letter.

This instrument incorporates the schedules to it.

References in this instrument to (1) the Company issuing and/or selling Warrant ADSs to the Warrantholder, and similar or analogous expressions, shall be understood to include references to the Company allotting and issuing the Warrant Shares underlying those Warrant ADSs to the Depositary or its nominee and procuring the issue of Warrant ADSs representing such Warrant Shares by the Depositary or its nominee to the Warrantholder; and (2) the purchase of, or payment for, any Warrant ADSs, and similar or analogous expressions, shall be understood to refer to the subscription for the Warrant Shares underlying those Warrant ADSs, as well as deposit of the Warrant Shares for Warrant ADSs representing such Warrant Shares, and the payment of the subscription monies in respect of such Warrant Shares.

CONSTITUTION AND FORM OF WARRANT

This instrument constitutes a Warrant which gives the Warrantholder the right, upon the terms and subject to the conditions set out in this instrument, to purchase for cash or by wire transfer of immediately available funds (if the Warrantholder did not notify the Company in the Notice of Purchase that such exercise was made pursuant to a Cashless Exchange (as defined in clause 2.3)) at a price per ADS equal to the Purchase Price up to an aggregate of U.S.$24,000,000. The Warrant may be exercised in whole or in part and from time to time before the Expiration Date.

The Warrantholder shall be entitled to purchase for cash at the Purchase Price that number of Warrant ADSs in respect of which it is entitled to be recorded as the holder in the Register on the terms set out in this instrument. Only a whole number of Warrant ADSs will be issuable and all fractional entitlements will be ignored.

Notwithstanding anything contained herein to the contrary, the Warrantholder may, in its sole discretion, elect to exchange all or any portion of this Warrant and, in lieu of making the cash payment otherwise contemplated to be made to the Company upon exercise in payment of the Purchase Price, elect to exchange all or any portion of its Warrant, by way of cashless exchange, for such number of Warrant ADSs calculated using the following formula (a “Cashless Exchange”):

the number of Warrant ADSs to be issued to the Warrantholder;

the number of Warrant ADSs that would be issued to the Warrantholder in respect of the Warrant being exchanged if they were exercised at full Purchase Price rather than by way of Cashless Exchange;

the Closing Price of the ADSs at the time of delivery of the Notice of Purchase giving rise to the applicable Cashless Exchange; and

the Purchase Price per Warrant Share.

The Warrant shall be in registered form.

The Warrant is issued subject to the Articles and otherwise on the terms of this instrument (including the Conditions).

The Company agrees with the Warrantholder and, in consideration of being issued the Warrant Certificate, the Warrantholder agrees with the Company that the Articles (insofar as they relate to the Warrant) and the terms of this instrument shall be binding upon the Company and the Warrantholder and all persons claiming through or under either of them.

No application will be made for the Warrant to be listed or dealt on any Recognised Exchange, including but not limited to Nasdaq.

The Warrant, the Warrant ADSs issuable on exercise of the Warrant, and the underlying Warrant Shares are not currently registered with the U.S. Securities and Exchange Commission (the “SEC”) under the United States Securities Act of 1933, as amended (the “Securities Act”), or with any securities regulatory authority of any state or other jurisdiction of the United States. The offer and sale of the Warrant, the Warrant ADSs issuable on exercise of the Warrant, and the underlying Warrant Shares are being made in the United States only to the Warrantholder as it is an “accredited investor” (as defined in Regulation D of the Securities Act) in a transaction not involving a public offering and which is exempt from, or not subject to, the registration requirements of the Securities Act. The Warrantholder has been informed that the Warrant, the Warrant ADSs, and the Warrant Shares, must be held indefinitely unless they are subsequently registered with the SEC on a registration statement under the Securities Act or an exemption from registration under Securities Act is available. Each Notice of Purchase and each notice of transfer of a Warrant shall contain the provisions contained in the schedules to the Warrant Certificate attached to this Warrant Instrument and such other warranties and representations as may be required by applicable securities laws. The exercise or transfer of the Warrant, and the right of the Warrantholder to receive the Warrant ADSs to be issued on the exercise of the Warrant (including the underlying Warrant Shares), shall be subject to such requirements, conditions, restrictions, limitations or prohibitions (together referred to as “Restrictions”) as the Company may reasonably require for the purposes of ensuring that such exercise, transfer or issuance, complies with (or for avoiding any requirement by the Company to comply with or register any securities under) the securities laws of the United States and any other relevant jurisdiction and will only be effective to the extent that such Restrictions are complied with. The Directors of the Company may request from any person exercising the Warrant or who is a transferee of the Warrant such information as they may reasonably require for determining whether such Restrictions will be applicable and, if so, whether they will be complied with.

WARRANT CERTIFICATES

The Company shall issue to the Warrantholder a Warrant Certificate in respect of the number of Warrant ADSs to which it is entitled to purchase upon exercise of the Warrant as soon as reasonably practicable following the execution of the Collaboration Agreement.

If a Warrant Certificate is mutilated, defaced, lost, stolen or destroyed, the Company will, on such terms as to evidence and indemnity as the Company may reasonably require, issue a replacement Warrant Certificate and subject to the Warrantholder who is seeking the replacement paying the Company’s reasonable costs (if any) in connection with the issue of the replacement.

A mutilated or defaced Warrant Certificate must be surrendered before a replacement Warrant Certificate will be issued.

TIMING FOR EXERCISE OF PURCHASE RIGHTS

The Purchase Rights may be exercised at any time from the Issue Date until 5:30 pm, GMT on the Expiration Date and shall be exercised in accordance with clause 5.

A failure by the Warrantholder to exercise its Purchase Rights ahead of such time on the Expiration Date shall mean that the Warrant shall immediately lapse and be cancelled and the Warrantholder shall have no further rights under this instrument.

EXERCISE OF PURCHASE RIGHTS

At the time of an exercise of the Purchase Rights, pursuant to clause 4.1, the Warrantholder shall exercise all such Purchase Rights and not, for the avoidance of doubt, part of these Purchase Rights.

In order to exercise its Purchase Rights validly, the Warrantholder must deliver the following items to the registered office of the Company:

the Warrant Certificate for the Warrant in respect of which Purchase Rights are being exercised, together with the Notice of Purchase duly completed;

the name and address of the Warrantholder to which the Warrant ADSs arising on exercise of Purchase Rights are to be issued, and such other information as may be reasonably requested by the Depositary; and

a completed Issuance and Delivery Instruction in the form set out at Schedule 3 hereto (as such form may be amended from time to time by notice to the Warrantholder) duly completed and executed, inter alia, by the Warrantholder.

Delivery of the items specified in clause 5.2 to the Company shall, unless the Company expressly consents otherwise, be an irrevocable election by the Warrantholder to exercise the relevant Purchase Rights.

The Warrantholder, solely in such person’s capacity as a holder of the Warrant, shall not be entitled to vote or receive dividends or be deemed the holder of the share capital of the Company for any purpose, nor shall anything contained in the Warrant be construed to confer upon the Warrantholder, solely in such person’s capacity as the holder of the Warrant, any of the rights of a shareholder of the Company or any right to vote, give or withhold consent to any corporate action (whether any reorganization, issue of shares, redesignation of shares, consolidation, merger, scheme of arrangement, conveyance or otherwise), receive notice of meetings, receive dividends or subscription rights, or otherwise, prior to the issuance to the Warrantholder of the Warrant ADSs which such person is then entitled to receive upon the due exercise of the Warrant. In addition, nothing contained in this Warrant shall be construed as imposing any liabilities on the Warrantholder to purchase any securities (upon exercise of this Warrant or otherwise) or as a shareholder of the Company, whether such liabilities are asserted by the Company or by creditors of the Company.

COMPLETION

Following a valid exercise of Purchase Rights by a Warrantholder, the Company shall in accordance with clause 6.3:

issue to, deposit with (and otherwise register in the name of) the custodian of the Depositary (or its nominee) the number of Ordinary Shares to be issued on the exercise of Purchase Rights (“Allotted Shares”) and following such issuance and deposit, the Company will direct the Depositary to promptly issue an amount of ADSs in book-entry form on the books and records of the Depositary (with such ADSs being ineligible for listing on Nasdaq or settlement through DTC) in accordance with the corresponding Issuance and Delivery Instruction; and

immediately following allotment and issue in accordance with clause 6.1.1, enter, or procure that the Company’s registrars enter the custodian of the Depositary’s name in the register of members of the Company as the holder of the Allotted Shares.

The obligations of the Company under clause 6.1 shall be fulfilled within five (5) Business Days after the Notice of Purchase is lodged at the registered office of the Company or as soon as reasonably practicable thereafter.

The Allotted Shares shall:

be allotted and issued fully paid;

rank pari passu with the Ordinary Shares then in issue;

rank for any dividend or other distribution which has previously been announced or declared if the date by which the holder of Warrant Shares must be registered to participate in such dividend or other distribution is after the Exercise Date pursuant to which the Purchase Rights have been exercised; and

be free from all claims, liens, charges, encumbrances, equities and third-party rights.

TRANSFER OF WARRANT

Subject to clause 7.2, the Warrant may be transferred in whole by the Warrantholder to any person, provided that the Company has given its prior written consent to such transfer.

The Warrantholder has the right, with prior written notice, but without the consent of the Company, to transfer the Warrant in whole to a Permitted Transferee, subject to compliance with the provisions of Schedule 2 hereto.

Notwithstanding any other provisions of this instrument, no transfer shall be made to any person which is a Competitor of the Company.

The provisions of Schedule 2 to this instrument shall regulate any transfer of a Warrant.

MODIFICATION AND CESSATION OF RIGHTS

This instrument, the Warrant and any term hereof may be changed, waived, discharged or terminated only by an instrument in writing signed by the Company and the Warrantholder.

This instrument ceases to have effect on the earlier of:

the date upon which all Purchase Rights have been exercised in full; and

the Expiration Date.

RESTRICTIONS ON AND UNDERTAKINGS OF THE COMPANY

For so long as the Warrant is outstanding, the Company will:

to the extent that the Company has a limit on its authorised share capital, keep available for issue and free from pre-emptive rights, out of its authorised but unissued share capital, such number of Warrant Shares as will enable the Purchase Rights of the Warrantholder to be satisfied in full; and

ensure that the Directors have all necessary authorisations and disapplications of pre-emption (including under the Companies Act and the Articles) to allot such number of Warrant Shares and procure the issue of such number of Warrant ADSs representing such Warrant Shares as will enable the Purchase Rights of the Warrantholder to be satisfied in full at any time.

INFORMATION AND CO-OPERATION IN EVENT OF ANY FILINGS

Should it be necessary or, in the Warrantholder’s view, reasonably advisable for the Warrantholder to obtain clearance for the exercise of the Warrant from any regulatory or governmental authority, the Company shall, and shall procure that any Group Company shall, if requested by the Warrantholder in writing, co-operate, to the extent legally permittable and reasonably requested, with the Warranholder in enabling the Warrantholder to obtain such clearance, or cause any applicable waiting periods to commence and expire as soon as reasonably practicable following such request, including providing such assistance and information as may be reasonably requested by the Warrantholder as soon as reasonably practicable following any such request, before and after the exercise of the Warrant; provided, however, that any costs including legal, clearance, filing, stamp duty reserve tax, or stamp duty costs or fees that result or are incurred in connection with fulfilling the objectives of this clause shall be borne by the Warrantholder.

Without prejudice to the generality of clause 10.1, in fulfilling the objectives of this clause, the Company shall, and shall procure that any Group Company shall:

provide any reasonably requested information, including any underlying documents, to the Warrantholder, as soon as reasonably practicable following a request to enable the Warrantholder to prepare any submissions to the relevant authority or respond to the relevant authority’s requests; and

make available, at the Warrantholder’s reasonable request and with reasonable notice, relevant personnel for calls and remote meetings with the relevant authority.

MISCELLANEOUS

The Warrantholder shall keep confidential any information received by it in its capacity as a Warrantholder which is of a confidential nature except:

as required by law or any applicable regulations;

to the extent the information is in the public domain through no default of the Warrantholder; and

the Warrantholder will be entitled to divulge such information to any proposed transferee of the Warrant on the same terms as to confidentiality.

Any notice to the Warrantholder required for the purposes of any provision of this instrument shall be given in accordance with the provisions of paragraphs 10 to 13 (inclusive) of Schedule 2.

The Company shall, at its own cost and expense, execute all such deeds and documents and do all such acts and things as may reasonably be required in order to give effect to this instrument, including the payment of any and all Depositary-related fees in connection with the issuance and maintenance of the Warrant ADSs, as well as the vesting on issue the full legal and beneficial title to the Warrant ADSs in the Warrantholder; provided, however, for purposes of clarity, that all stamp duty taxes, including, without limitation, the U.K. Stamp Duty Reserve Tax, will be paid by the Warrantholder to the extent such taxes are payable in respect of the deposit of the Warrant Shares and the issuance and delivery of the Warrant ADSs as contemplated herein.

Each of the provisions of this instrument is distinct and severable from the others and if at any time one or more of such provisions is or becomes valid, unlawful or unenforceable (whether wholly or to any extent), the validity, lawfulness and enforceability of the remaining provisions (or the same provision to any other extent) of this instrument shall not in any way be affected or impaired.

The provisions of this instrument and the Conditions and any dispute or claim arising out of or in connection with them (including any dispute or claim relating to non-contractual obligations) shall be subject to and governed by the laws of the State of Delaware and the Company and the Warrantholder submit to the exclusive jurisdiction of the courts of the State of Delaware in relation to any such dispute or claim.

An accurate Register listing the contact information of the Warrantholder will be kept and maintained at all times by the Company at its registered office.

Any change in the name or address of the Warrantholder shall promptly be notified to the Company which shall cause the Register to be altered accordingly. The Warrantholder or any person authorised by the Warrantholder shall be at liberty at all reasonable times during office hours to inspect the Register and to take copies of or extracts from it or any part of it.

The Company shall be entitled to treat the Warrantholder as the absolute owner of the Warrant and accordingly shall not, except as ordered by a court of competent jurisdiction or as required by law, be bound to recognise any equitable or other claim to or interest in the Warrant on the part of any other person, whether or not it shall have express or other notice of such a claim.

The Warrantholder will be recognised by the Company as entitled to the Warrant free from any equity, set-off or cross-claim on the part of the Company against the original or any intermediate holder of the Warrant.

Each transfer of a Warrant shall be made by an instrument of transfer in the form or substantially in the form set out in the second schedule to the Warrant Certificate or in any other form which may be approved for the time being by the Directors.

The instrument of transfer of a Warrant shall be executed by or on behalf of the transferor and by or on behalf of the transferee. The transferor shall be deemed to remain the holder of the Warrant until the name of the transferee is entered in the Register in respect of the Warrant being transferred.

The Directors may decline to recognise any instrument of transfer of a Warrant unless the instrument, executed by both the transferor and transferee, is deposited at the registered office of the Company accompanied by the Warrant Certificate for the Warrant to which it relates, and such other evidence as the Directors may reasonably require to show the right of the transferor to make the transfer. The Directors may also decline to recognise or register any transfer of a Warrant if in the reasonable opinion of the Directors, having taken legal advice, such transfer would violate the securities laws of any country, state or jurisdiction, or require the Company to register the Warrant under the applicable securities laws of such country, state or jurisdiction. The Directors may waive production of any Warrant Certificate upon production to them of satisfactory evidence of the loss or destruction of the Warrant Certificate together with such indemnity as they may require.

No fee shall be charged for any registration of a transfer of a Warrant or for the registration of any other documents which in the opinion of the Directors require registration.

The registration of a transfer shall be conclusive evidence of the approval by the Directors of such a transfer.

The Warrantholder shall register with the Company an address in the United Kingdom to which notices can be sent. If the Warrantholder fails to register an address with the Company, notice may be given to the Warrantholder by sending it by any of the methods referred to in paragraph 11 of this Schedule 2 to that Warrantholder’s last known place of business or residence or, if none, by exhibiting it for three days at the registered office for the time being of the Company.

Notices and other communications to the Warrantholder may be given by personal delivery, prepaid letter by first class post or, subject to clause 1.3 of this instrument, fax or email. In proving service of any notice or other communication sent by post, it shall be sufficient to prove that the envelope containing the notice or other communication was properly addressed and stamped and was deposited in a post box or at the post office.

A notice or other communication given pursuant to the provisions of paragraph 11 of this Schedule 2 shall be deemed to have been served:

at the time of delivery, if delivered personally to the registered address;

on the second Business Day following its posting, if sent by prepaid letter by first class post to an address in the United Kingdom; and

at 09:00 hours on the Business Day following the despatch of the fax, if sent by fax.

Any person who, whether by operation of law, transfer or other means whatsoever, shall become entitled to any Warrant, shall be bound by every notice in respect of such Warrant which, prior to its name and address being entered on the Register, shall have been duly given to the person from which it derives its title to such Warrant.

When a given number of days’ notice or notice extending over any other period is required to be given, the day of service shall be included but the day upon which such notice will expire shall not be included in such number of days or other period. The signature to any notice to be given by the Company may be written or printed.
