NOW THIS DEED OF GUARANTEE
WITNESSETH as follows:


 


ARTICLE 1


Existing Finance Contract and Amended
and Restated Finance Contract


 


	1.01	The Guarantor acknowledges notice of the provisions of the Second Amendment and Restatement Agreement,
the First Amended and Restated Finance Contract and the Amended and Restated Finance Contract, and confirms its acceptance of the
provisions thereof. Unless otherwise defined herein, capitalised terms used herein and defined in the Amended and Restated Finance
Contract (whether or not the Effective Date has occurred) shall have the same meaning where used herein. In addition, "Effective
Date" shall have the meaning given to that term in the Second Amendment and Restatement Agreement.



 


ARTICLE 2


Guarantee


 


	2.01	In consideration of the Bank entering into the Second Amendment and Restatement Agreement the Guarantor
hereby irrevocably and unconditionally (unbedingt, unwiderruflich) guarantees to the Bank the due and punctual payment and
performance of all present, future and contingent, express or implied debts, obligations and liabilities (including, without limitation,
principal, interests, interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency,
reorganization or like proceeding, relating to the Guarantor, OpGen, the Borrower or any other guarantor or surety), expense, commission,
indemnity or other sum) of the Borrower (whether solely or jointly with one or more persons and whether as principal or as surety
or in some other capacity and whether originally owing to that person claiming performance or acquired by that person from someone
else) to the Bank under or in connection with the Existing Finance Contract (collectively, the "Liabilities",
and each, a "Liability") and the payment of all Guaranteed Sums in accordance with the Existing Finance Contract
upon first demand and without raising any defenses or objections, set-off or counterclaim and without verification of the legal
ground (auf erste Aufforderung und unter Verzicht auf alle Einwendungen oder Einreden, ohne Aufrechnung oder die Geltendmachung
von Gegenforderungen und ohne Prüfung des Rechtsgrunds). The Guarantor undertakes that, if the Borrower should fail to
pay or otherwise discharge any Guaranteed Sum or any Liability to the Bank in accordance with the Existing Finance Contract whether
upon the normal due date, upon acceleration or otherwise, the Guarantor shall unconditionally pay the sum in question to the Bank
on demand in full and without set-off (including against the Borrower or the Bank) as if the Guarantor were the principal obligor,
in the currency specified in the Existing Finance Contract and to the account specified in the demand (unless such payment is subject
to any withholding tax or similar deductions, in which case the Guarantor will pay an additional amount so that the Bank receives
the full amount it would have received if no deductions were due).



 


 






    	3  





    	 



    

 


For the purposes of this Guarantee, a "Guaranteed
Sum" means an amount equal to 100% (one hundred per cent) of the outstanding principal, interest (including, without limitation,
interest accruing after the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like
proceeding, relating to the Guarantor, OpGen, the Borrower or any other guarantor or surety), expense, commission, indemnity, claim
for damages or other sum owed by the Borrower to the Bank then outstanding under the Existing Finance Contract (whether actual
or contingent, and references to the Guaranteed Sum include references to any part of it).


 


The Guarantor further agrees and undertakes
to pay interest to the Bank at the rate and on the terms specified in the Existing Finance Contract for payment of overdue sums
on all sums demanded under this Guarantee (before and after any judgment and including, without limitation, interest accruing after
the filing of any petition in bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to
the Guarantor, OpGen, the Borrower or other guarantor or surety) from the due date thereof until the date of receipt of such sum
by the Bank, provided that if and to the extent that interest is accruing on any Guaranteed Sum under the Existing Finance Contract
itself at the rate specified in Article 3.03 (Interest on overdue sums) of the Existing Finance Contract then payment of
the relevant Guaranteed Sum together with such accrued interest shall satisfy the obligation of the Guarantor hereunder in respect
of the relevant Guaranteed Sum and no additional interest shall accrue under this paragraph on such amount.


 


	2.02	The obligations of the Guarantor hereunder are those of a primary obligor and not merely those
of a surety. Neither the obligations of the Guarantor under this Guarantee nor the rights, powers or remedies conferred upon the
Bank in this Guarantee or by law shall be impaired, discharged or otherwise affected by reason of:



 


		a.	any illegality, invalidity, ineffectiveness or unenforceability in or of the terms of any Finance
Document or any other security for the Liabilities;



 


		b.	any disability, incapacity or lack of power, authority or legal personality or change in status
or constitution of the Borrower, OpGen, the Bank or any other person;



 


		c.	any winding-up, dissolution, administration, re-organisation, liquidation, insolvency or other
similar procedure in respect of the Borrower, OpGen, the Guarantor or any other person or any change in the status, function, control
or ownership of the Borrower, OpGen, the Guarantor or of any other person or the claiming, proving for, accepting or transferring
any payment in respect of the Guaranteed Sum in any winding-up, dissolution, administration, re-organisation, liquidation, insolvency
or composition of the Borrower, OpGen, the Guarantor or any other person or abstaining from so claiming, proving for, accepting
or transferring;



 


		d.	any time or other indulgence agreed or granted by the Bank or any arrangement entered into or composition
accepted by the Bank, varying the rights of the Bank under any Finance Document or any other security arrangement;



 


		e.	any release of the Borrower, OpGen or any other person under the terms of any composition or arrangement
with any creditor of any member of the Group;



 


		f.	any forbearance or delay on the part of the Bank in asserting any of its rights against the Borrower
under under the Existing Finance Contract or any other Finance Document, or against any party to a Guarantee Agreement under the
Guarantee Agreement to which that person is a party;



 


		g.	any other guarantee or Security which the Bank now has or may hereafter acquire with respect to
the Borrower's or any other person’s obligations under the Existing Finance Contract, any Finance Document, or any related
agreement including, but not limited to any Guarantee Agreement;



 


		h.	any amendment to, or any variation, waiver, assignment, novation, supplement, extension, restatement,
replacement or release of (in each case, however fundamental and whether or not more onerous), the Existing Finance Contract, any
Guarantee Agreement, any other Finance Document or any other document or security (including, without limitation, any change in
the purpose, time, manner or place of payment, any extension of or any increase in any facility or the addition of any new facility
under the Existing Finance Contract), the Guaranteed Sums or the Liabilities or any of them or any security (or of any person thereunder)
held by the Bank in respect thereof;



 


 






    	4  





    	 



    

 


		i.	the taking, acceptance, variation, compromise, exchange or renewal of any security or any total
or partial failure to take or perfect any security proposed to be taken in respect of any Guaranteed Sums or Liabilities or any
total or partial failure to realise the value of, or any surrender, release, discharge, exchange or substitution of, any security
held by the Bank in respect of any Guaranteed Sum or Liabilities or any non-presentation or non-observance of any formality or
other requirement in respect of any instrument; or



 


		j.	any other act, event, omission or circumstance, which, but for this Article 2.02, might otherwise
discharge, impair or otherwise affect any of the obligations of the Guarantor contained in this Guarantee or any of the rights,
powers or remedies conferred upon the Bank by this Guarantee or by law.



 


This Guarantee is in
addition to and is not in any way prejudiced by any other guarantee or security now or subsequently held by the Bank including,
but not limited to, each Guarantee Agreement.


 


The Guarantor shall comply, mutatis
mutandis, with all covenants set out in the Existing Finance Contract which refer directly or indirectly (including by means
of requiring the Borrower to procure that the other Obligors comply with such covenants) to the Guarantor as if such covenants
were incorporated into this Guarantee and were expressed to be incumbent upon the Guarantor.


 


	2.03	As an independent, continuing and primary obligation additional
to and separate from those set out in Articles 2.01 and 2.02, and without prejudice to the validity or enforceability of those
obligations, the Guarantor unconditionally and irrevocably undertakes (as a primary obligor and not merely as surety) that, if
any Guaranteed Sum should not be recoverable in whole or in part from the Guarantor under Article 2.01 for whatsoever reason (including
as a result of the Existing Finance Contract or any of the Guaranteed Sums being or becoming void, voidable, unenforceable or ineffective
as against the Borrower for any reason whatsoever) and whether or not the reason may have been known to the Bank or any other person
at any material time, the Guarantor shall as if the Guarantor were a sole and independent obligor, fully indemnify, compensate
and hold harmless the Bank by way of a full indemnity for all costs, losses, damages, expenses, claims or liabilities resulting
from: (a) the failure of the Borrower to duly and punctually make payment of any Guaranteed Sum in the amount and currency provided
for by or pursuant to the Existing Finance Contract whether upon the normal due date, upon acceleration or otherwise; or (b) any
Liability being or becoming void, voidable, unenforceable or ineffective as against the Borrower for any reason whatsoever, whether
or not known to the Bank, the amount of such loss being the amount which the Bank would have been entitled to recover from the
Borrower but for such Liability being or becoming void, voidable, unenforceable or ineffective as against the Borrower.



 


	2.04	This Guarantee is a continuing security and the obligations of the Guarantor under this Guarantee
shall constitute and be continuing obligations notwithstanding any settlement of account or other matter or thing whatsoever, and
shall endure until all Guaranteed Sums have been fully and finally paid or discharged and shall not be released or discharged by
any intermediate payment or settlement of the Guaranteed Sums or of any of them or by any intermediate satisfaction of all or any
of the obligations of the Borrower in relation to any of the Liabilities. This Guarantee shall continue in full force and effect
until final payment in full of all amounts owing by the Borrower in respect of the Liabilities and total satisfaction of all the
Borrower's actual and contingent obligations in relation to the Liabilities. No payment or discharge which may be avoided under
any enactment relating to insolvency, bankruptcy, voluntary or involuntary dissolution or winding up of the Borrower, OpGen, the
Guarantor or any other person, no payment or discharge made or given which is subsequently avoided and no release, return, cancellation
or discharge of this Guarantee given or made or any other agreement reached between the Bank and the Guarantor on the faith of
any payment or discharge aforesaid shall constitute discharge of the Guarantor under this Guarantee or prejudice or affect the
Bank's right to recover from the Guarantor to the full extent of this Guarantee, and any such discharge, release, return, cancellation
or agreement shall be deemed always to have been void. This is a guarantee of payment and not a deficiency guarantee. The originals
of this Guarantee which are in the possession of the Bank shall remain the property of the Bank after any release, cancellation
or discharge of this Guarantee.



 


 






    	5  





    	 



    

 


	2.05	If any discharge, release or arrangement (whether in respect of the obligations of the Borrower
or any security for those obligations or any Guarantee Agreement or otherwise) is made by the Bank in whole or in part on the faith
of any payment security or other disposition which is avoided or must be restored in an insolvency, liquidation, administration
or otherwise, without limitation, then the liability of the Guarantor under this Guarantee will continue or be reinstated as if
the discharge, release or arrangement had not occurred.



 


	2.06	Any money received, recovered or realised in connection with this Guarantee (including the proceeds
of any conversion of currency) may be placed by the Bank in its discretion to the credit of a suspense or impersonal interest bearing
account, with a view to preserving the right of the Bank to prove for the whole of the claims against the Borrower or may be applied
by the Bank in or towards satisfaction of such of the Guaranteed Sums as the Bank in its absolute discretion may from time to time
determine; provided, however, that if any such money, being freely disposable by the Bank, is not applied towards satisfaction
of the Guaranteed Sums for which payment of the money was made hereunder, the Guarantor's responsibility in respect of the Guaranteed
Sums shall be discharged to the extent of such payment and the interest accrued thereon.



 


	2.07	The Guarantor agrees that until all the Guaranteed Sums have been irrevocably fully paid or discharged
and so long as the Borrower is under any actual or contingent obligations in respect of the Liabilities, the Guarantor shall:



 


	(a)		not exercise any rights which it may at any time have by reason of performance by
it of its obligations under this Guarantee or by reason of any amount being payable, or liability arising, under this Guarantee
to:



 


	(i)		be indemnified by the Borrower or OpGen or to receive any collateral from the Borrower
or OpGen; and/or



		(ii)	claim any contribution from any other guarantor of any of the Liabilities or Guaranteed Sums including
without limitations OpGen; and/or



		(iii)	take the benefit (in whole or in part and whether by way of subrogation or otherwise) of any rights
of the Bank in respect of any of the Liabilities or Guaranteed Sums or of any other security or any Guarantee Agreement, taken
by the Bank pursuant to, or in connection with, any of the Liabilities or Guaranteed Sums; and/or



		(iv)	bring any legal or other proceedings for an order requiring the Borrower or OpGen to make any payment,
or perform any obligation, in respect of which the Guarantor has given a guarantee, undertaking or indemnity pursuant to this Guarantee;
and/or



		(v)	exercise any right of set-off against the Borrower or OpGen; and/or



		(vi)	claim or prove as a creditor of the Borrower or OpGen in competition with the Bank;



 


		(b)	not seek to enforce any obligation owed to it by the Borrower or OpGen (including rights of set-off)
which arises by virtue of the discharge by the Guarantor of its obligations hereunder and if the Guarantor receives any benefit,
payment or distribution in relation to or as a result of discharging its obligations hereunder it will promptly pay an equal amount
to the Bank;



 


		(c)	pay to the Bank all dividends or distributions in liquidation or otherwise received by it from
or for the account of the Borrower or OpGen in respect of any obligation referred to in paragraph (b) above; the Bank shall apply
such sums to reduce the outstanding Guaranteed Sums in such sequence as it may decide;



 


 






    	6  





    	 



    

 


		(d)	have no right of subrogation to the rights of the Bank under the Existing Finance Contract, any
Guarantee Agreement, any other Finance Document or any related security arrangement;



 


		(e)	comply with the terms of and do all that is necessary to maintain in full force and effect all
authorisations, approvals, licences and consents required in or by the laws and regulations of England and Wales and the jurisdiction
of incorporation of the Guarantor to enable the Guarantor lawfully to enter into and perform its obligations under this Guarantee
and to ensure the legality, validity, enforceability and admissibility in evidence in England and Wales of this Guarantee;



 


		(f)	not take any action which would cause any of the representations made in Article 6 below to be
untrue at any time during the continuation of this Guarantee; and



 


		(g)	notify the Bank of the occurrence of any event which results in or may reasonably be expected to
result in any of the representations made in Article 6 below being untrue when made or when deemed to be repeated.



 


	2.08	If the Guarantor receives any benefit, payment or distribution in relation to any of the rights
set out in Article 2.07(a)(i) to (vi), the Guarantor shall hold on trust for the Bank that benefit, payment or distribution to
the extent necessary to enable all amounts which may be or become payable to the Bank by the Borrower, OpGen and/or the Guarantor
under or in connection with the Existing Finance Contract, any Guarantee Agreement, this Guarantee, and/or any other Finance Document
to be repaid in full and shall promptly pay or transfer the same to the Bank as the Bank may direct.



 


	2.09	The Guarantor acknowledges: (i) that it has entered into this Guarantee on the basis of its own
assessment of the Borrower and any security provided, and (ii) that it has not been induced to enter into this Guarantee by any
representation made by the Bank. The Bank is not obliged to report to the Guarantor on the financial position of the Borrower,
OpGen or of any other guarantor or on any security provided. The Bank shall have no liability to the Guarantor for granting or
disbursing the Loan, for cancelling or suspending, or not cancelling or suspending the Credit or for demanding or not demanding
prepayment under the Existing Finance Contract (or any other Finance Document) or for performing its obligations, or exercising
or not exercising its rights, under the Existing Finance Contract (or any other Finance Document).



 


	2.10	The obligations of the Guarantor contained in this Guarantee shall be in addition to, independent
of and in no way prejudiced by any other security or any other guarantee including, without limitation, each Guarantee Agreement,
that the Bank holds or may at any time hold in relation to any of the Liabilities or the Guaranteed Sums.



 


	2.11	The Bank may set off any matured obligation due from the Guarantor under this Guarantee (to the
extent beneficially owned by the Bank) against any obligation (whether or not matured) owed by the Bank to the Guarantor regardless
of the place of payment, booking branch or currency of either obligation. If the obligations are in different currencies, the Bank
may convert either obligation at a market rate of exchange in its usual course of business for the purpose of the set-off. If either
obligation is unliquidated or unascertained, the Bank may set off in an amount estimated by it in good faith to be the amount of
that obligation.



 


	2.12	For the avoidance of any doubt, this Guarantee is meant to be and shall be interpreted as an “abstract
guarantee” (abstrakter Garantievertrag) and the obligations of the Guarantor hereunder shall be obligations of such
Guarantor as principal debtors and not as sureties (Bürgschaft) and not as co-debtors as a borrower (Mitschuldner).



 


 






    	7  





    	 



    

 


	2.13	Notwithstanding any provision in this Guarantee or any other Finance Document, the obligations
(Verpflichtungen) and liabilities (Haftungen) of the Guarantor under this Guarantee or any other Finance Document
shall be at all times limited so that at no time the Guarantor shall assume any liability (Haftung) or obligation (Verpflichtung)
to pay or settle any amount under this Guarantee or any other Finance Document to the extent that such liability (Haftung)
or obligation (Verpflichtung) would violate mandatory Austrian capital maintenance rules (Kapitalerhaltungsvorschriften)
pursuant to Austrian corporate law, in particular section 82 et seq. of the Austrian Act on Limited Liability Companies (Gesetz
über Gesellschaften mit beschränkter Haftung - GmbHG) and/or sections 52 and 65 et seq. of the Austrian Stock Corporation
Act (Aktiengesetz - AktG) (for the purpose of this clause 2, the "Austrian Capital Maintenance Rules").
Should any obligation (Verpflichtung) or liability (Haftung) of the Guarantor under this Guarantee or any other Finance
Document violate or contradict Austrian Capital Maintenance Rules and therefore be held invalid or unenforceable, or in case the
assumption or enforcement of such obligation (Verpflichtung) or liability (Haftung) exposes the managing directors
of the Guarantor to personal liability or criminal responsibility, such obligation (Verpflichtung) or liability (Haftung)
shall be reduced to an obligation (Verpflichtung) or liability (Haftung) of a similar nature which is in compliance
with Austrian Capital Maintenance Rules. By way of example, should it be held that the guarantee and indemnity pursuant to this
Guarantee or any other Finance Document contradicts Austrian Capital Maintenance Rules in relation to any amount of the guaranteed
claims (garantierte Forderungen), the obligations (Verpflichtungen) and liabilities (Haftungen) under the
guarantee and indemnity shall be reduced to a maximum amount which is permitted pursuant to Austrian Capital Maintenance Rules
without breaching Austrian Capital Maintenance Rules. The Parties acknowledge that the limitations set out in this Article 2.13
may reduce any payment permissible at a given time by the Guarantor under this Guarantee or any other Finance Document to a small
amount or even zero.



 


	2.14	The Guarantor shall not either in a single transaction or in a series of transactions, whether
related or not and whether voluntarily, or involuntarily, dispose of all or any part of the Guarantor’s business, undertaking
or assets, unless:



 


(a)
with the prior written consent of the Bank; or


 


(b)
such disposal is a Permitted Disposal.


 


	2.15	The Guarantor shall comply in all respects with all laws and regulations to which it or the Project
is subject.



 


	2.16	The Guarantor shall procure that no substantial change is made to the core business of the Guarantor
as a whole from that carried on at the date of this Guarantee.



 


	2.15	The Guarantor shall not enter into any amalgamation, demerger, merger or corporate reconstruction,
unless:



 


(a)
with the prior written consent of the Bank; or


 


(b)
such amalgamation, demerger, merger or corporate reconstruction is a Permitted Merger.


 


	2.16	The Guarantor shall not invest in or acquire any entity or a business going concern or an undertaking
(whether whole or substantially the whole of the assets or business), or any division or operating unit thereof, or any shares
or securities of any entity or a business or undertaking (or in each case, any interest in any of them) (or agree to any of the
foregoing), unless:



 


		(a)	 with the prior written consent of the Bank; or



 


(b) such acquisition is a Permitted Acquisition.


 


	2.17	The Guarantor shall not incur any Indebtedness, unless:



 


 






    	8  





    	 



    

 


(a) with the prior written consent of the
Bank; or


 


(b) such Indebtedness is Permitted Indebtedness.


 


	2.18	The Guarantor shall not issue or allow to remain outstanding any guarantees in respect of any liability
or obligation of any person unless:



 


(a) with the prior written consent of the
Bank; or


 


(b) such guarantees are Permitted Guarantees.


 


	2.19	The Guarantor shall not declare or distribute dividends, or return or purchase shares unless:



 


(a) with the prior written consent of the
Bank; or


 


(b) such payments are Permitted Payments.


 


	2.20	The Guarantor shall ensure that it has kept and will continue to keep proper books and records
of account, in which full and correct entries shall be made of all financial transactions and the assets and business of
the Guarantor, including expenditures in connection with the Project, in accordance with GAAP as in effect from time to time.



 


	2.21	The Guarantor shall not (and the Guarantor shall ensure that no other member of the Group will)
create or permit to subsist any Security over any of its assets other than Permitted Security.



 


	2.22	For the purposes of Article 2.21, the term Security shall also include any arrangement or transaction
on assets or receivables or money (such as the sale, transfer or other disposal of assets on terms whereby they are or may be leased
to or re-acquired by the Guarantor or any other member of the Group, the sale, transfer or otherwise dispose of any receivables
on recourse terms or any arrangement under which money or the benefit of a bank account or other account may be applied or setoff
or any preferential arrangement having a similar effect) in circumstances where the arrangement or transaction is entered into
primarily as a method of raising credit or of financing the acquisition of an asset.



 


	2.23	The Guarantor shall notify the Bank of any Event of Default under the Existing Finance Contract
promptly upon becoming aware of its occurrence.



 


 


ARTICLE 3


Enforcement of Guarantee


 


 


	3.01	A notice from the Bank as to any default by the Borrower in the payment of any Guaranteed Sum which
sets out the basis of the calculation in reasonable detail shall be conclusive against the Guarantor save in the event of a manifest
or proven error.



 


	3.02	The Guarantor undertakes to pay all sums due hereunder in full, free of set-off or counterclaim.
