The meanings of the terms used in this deed are set out below.

Words which begin with a capital letter and are not defined in this Deed but are defined in the Agreement for Lease have the same meaning in this Deed.

Clause 35.1 (Interpretation) of the Agreement for Lease will apply to the interpretation of this Deed as if set out in full herein.

Clauses 37 (Landlord Trustee Limitation of Liability), 38 (Performance Guarantor Limitation of Liability) and 39 (Financial Guarantor Limitation of Liability) of the Agreement for Lease are incorporated into this Deed as if set out in full in this document.

With effect from the Effective Date, the Incoming Guarantor gives the guarantee and indemnity in the form attached in Schedule 1 (on the basis that the Incoming Guarantor is

the “Atlassian Guarantor” in that schedule) with respect to the Tenant’s obligations under the Agreement for Lease, whether such obligations arise before or after the Effective Date, in return for the other Parties releasing the Outgoing Guarantor from its obligations under clause 25 of the Agreement for Lease which arise after the Effective Date (Replacement Guarantee). The Incoming Guarantor acknowledges that the Developer is acting in reliance on the Incoming Guarantor incurring obligations and giving rights under this clause 2.1 and the Replacement Guarantee.

The Parties acknowledge and agree that with effect on and from the Effective Date:

(a)the Original Guarantee is terminated; and

(b)the Parties release and discharge the Outgoing Guarantor from all claims and demands of any nature, which any of them has or may in the future have had against the Outgoing Guarantor, arising out of the obligations of the Outgoing Guarantor under the Original Guarantee which arise after the Effective Date.

The Parties acknowledge and agree that with effect on and from the Effective Date, the definition of “Atlassian Guarantor” is deleted and replaced with the following:

Clause 30 of the Agreement for Lease is incorporated into this Deed as if set out in full herein.

(a)This Agreement is governed by the Law in force in New South Wales.

(b)Each Party irrevocably and unconditionally submits to the non-exclusive jurisdiction of the courts of New South Wales.

This Deed constitutes the entire agreement of the Parties about its subject matter and supersedes all previous agreements, understandings and negotiations on that subject matter.

Each party must promptly do all further acts and execute and deliver all further documents (in such form and content reasonably satisfactory to both parties) required by Law or reasonably requested by another party to give effect to this Deed.

(a)A provision of or a right created under this Agreement may not be waived or varied except in writing signed by the Party or parties to be bound.

(b)A failure to exercise or enforce, a delay in the exercise or enforcement of or the partial exercise or enforcement of a right provided by law by a party does not preclude, or operate as a waiver of, the exercise or enforcement, or further exercise or enforcement, of that or any other right provided by Law or under this Deed.

(c)No waiver of a breach of a term of this Deed operates as a waiver of another breach of that term or of a breach of any other term of this Deed.

If the whole or any part of a provision of this Deed is void, unenforceable or illegal in a jurisdiction it is severed for that jurisdiction. The remainder of this Deed has full force and effect and the validity or enforceability of that provision in any other jurisdiction is not affected. This clause 5.5 has no effect if the severance alters the basic nature of this Deed.

This Deed may be executed in any number of counterparts and by the parties in separate counterparts. Each counterpart constitutes the deed of each party who has executed and delivered that counterpart. All such counterparts taken together will be deemed to constitute one and the same Deed.

Each Party represents and warrants that:

(a)it has full power and authority to enter into and perform its obligations under this Deed;

(b)it has taken all necessary action to authorise the execution, delivery and the performance of this Deed and the execution and delivery of this Deed will not breach or conflict with any other agreement or undertaking to which it is a party or subject; and

(c)this Deed constitutes its legal, valid and binding obligations, enforceable in accordance with its terms.

Without limiting clause 5.7, each party warrants that by entering into this Agreement, it has unconditionally consented to:

(a)the requirements for a signature under any Laws being satisfied; and

(b)other parties executing this Deed,

by using any method of electronic signature permitted by Law (including DocuSign, Adobe Sign, signing on an electronic device or by digital signature).

If this Deed is signed by a party by use of an electronic signature, then that party:

(a)agrees that other parties may rely on the electronic signature as having the same force and effect as a handwritten signature; and

(b)unconditionally consents to any method the other parties use (at their discretion) to identify the signatories and confirm their intention to enter into a binding legal agreement.

The Atlassian Guarantor unconditionally and irrevocably guarantees to the Developer the due and punctual performance and observance by the Tenant of the Tenant’s obligations under the Agreement for Lease (Tenant Obligations). If the Tenant does not perform or observe the Tenant Obligations in accordance with the provisions of the Agreement for Lease, then the Atlassian Guarantor agrees to perform and observe the Tenant Obligations for the benefit of the Developer on demand from the Developer (provided the Developer has first made a written demand on the Tenant to perform those Tenant Obligations which has not been satisfied by the Tenant within 10 Business Days after the demand being made). A demand may be made at any time and from time to time.

Whether or not the Developer exercises any rights it may have under clause 28.3 of the Agreement for Lease, and without being affected by the exercise of any such rights, the Atlassian Guarantor unconditionally and irrevocably indemnifies the Developer against any Loss the Developer suffers because:

(a)the liability to perform or observe the Tenant Obligations are unenforceable against the Tenant in whole or in part as a result of lack of capacity, power or authority or improper exercise of power or authority;

(b)the Tenant does not observe, perform or comply with (whether full or in part) the Tenant Obligations after written demand to perform them has been made on the Tenant;

(c)an Insolvency Event occurs in respect of the Tenant; or

(d)the Tenant Obligations are not or have never been enforceable against the Atlassian Guarantor or are not capable of observance, performance or compliance in full because of any other circumstance whatsoever including any transaction relating to the Tenant Obligations being void, voidable or unenforceable and whether or not the Developer knew or should have known anything about that transaction.

The Atlassian Guarantor as principal debtor agrees to pay to the Developer on demand a sum equal to the amount of any Loss described in clause 1.3, subject to this clause 1.

The guarantee provided in clause 1.2 and the indemnities provided in clause 1.3 are a continuing security and extend to all of the Tenant Obligations. The Atlassian Guarantor waives any right it has of first requiring the Developer to commence proceedings or enforce any other right against the Tenant or any other person before claiming from the Atlassian Guarantor under the Agreement for Lease other than the Developer having first made written demand on the Tenant to perform those Tenant Obligations which demand has not been satisfied by the Tenant within 10 Business Days after the demand being made.

The liabilities under the Agreement for Lease of the Atlassian Guarantor as a guarantor under clause 1.2 or an indemnifier under clause 1.3 and the rights of the Developer under the Agreement for Lease are not affected by anything which might otherwise affect them at Law or in equity including, without limitation, one or more of the following (whether occurring with or without the consent of a person):

(a)the Developer or another person granting time or other indulgence (with or without the imposition of an additional burden) to, compounding or compromising with, or wholly or partially releasing, the Tenant, any other indemnifier or another person in any way;

(b)laches, acquiescence, delay, acts, omissions or mistakes on the part of the Developer or another person or both the Developer and another person;

(c)any variation or novation of a right of the Developer or another person, or material alteration of the Agreement for Lease, in respect of the Tenant, the Atlassian Guarantor or another person;

(d)the transaction of business, expressly or impliedly, with, for or at the request of the Tenant, the Atlassian Guarantor or another person;

(e)changes which from time to time may take place in the membership, name or business of a firm, partnership, committee or association whether by death, retirement, admission or otherwise, whether or not the Atlassian Guarantor or another person was a member;

(f)a security interest being void, voidable or unenforceable;

(g)a person dealing in any way with a security interest, guarantee, judgment or negotiable instrument (including, without limitation, taking, abandoning or releasing (wholly or partially), realising, exchanging, varying, abstaining from perfecting or taking advantage of it);

(h)the death of any person or an Insolvency Event occurring in respect of any person;

(i)a change in the legal capacity, rights or obligations of a person;

(j)the fact that a person is a trustee, nominee, joint owner, joint venturer or a member of a partnership, firm or association;

(k)a judgment against the Tenant or another person;

(l)the receipt of a dividend after an Insolvency Event occurs in respect of a person or the payment of a sum or sums into the account of the Tenant or another person at any time (whether received or paid jointly, jointly and severally or otherwise);

(m)any part of the Tenant Obligations being irrecoverable;

(n)the acceptance of repudiation or other termination in connection with the Tenant Obligations;

(o)the invalidity or unenforceability of an obligation or liability of a person other than the Atlassian Guarantor;

(p)invalidity or irregularity in the execution of the Agreement for Lease by the Atlassian Guarantor or any deficiency in or irregularity in the exercise of the powers of the Atlassian Guarantor to enter into or observe its obligations under the Agreement for Lease;

(q)any obligation of the Tenant being discharged by operation of Law or otherwise; or

(r)property secured under a security interest being forfeited, extinguished, surrendered, resumed or determined.

As long as the Tenant Obligations remain unperformed or other money payable under this Agreement remains unpaid, the Atlassian Guarantor cannot without the consent of the Developer:

(a)in reduction of their liability under this Agreement, raise a defence, set-off or counterclaim available to them, the Tenant or a co-surety or co-indemnifier against the Developer or claim a set-off or make a counterclaim against the Developer;

(b)make a claim or enforce a right (including, without limitation, an encumbrance) against the Tenant or against their estate or property;

(c)prove in competition with the Developer if an Insolvency Event occurs in respect of the Tenant whether in respect of an amount paid by the Atlassian Guarantor under this Agreement, in respect of another amount (including the proceeds of a security interest) applied by the Developer in reduction of the Atlassian Guarantor’s liability under the Agreement for Lease, or otherwise; or

(d)claim to be entitled by way of contribution, indemnity, subrogation, marshalling or otherwise to the benefit of a security interest or guarantee or a share in it now or subsequently held for the Tenant Obligations.

The Developer’s rights under the Agreement for Lease are additional to and do not merge with or affect and are not affected by:

(s)any security interest now or subsequently held by the Developer from the Tenant, the Atlassian Guarantor or any other person; or

(t)any other obligation of the Atlassian Guarantor to the Developer,

notwithstanding any rule of Law or equity or any statutory provision to the contrary.

If a claim is made that all or part of a payment, obligation, settlement, transaction, conveyance or transfer in connection with the Tenant Obligations is void or voidable under Law relating to an Insolvency Event or the protection of creditors or for any other reason and the claim is upheld, conceded or compromised, then:

(a)the Developer is entitled immediately as against the Atlassian Guarantor to the rights in respect of the Tenant Obligations to which it would have been entitled if all or that part of that payment, obligation, settlement, transaction, conveyance or transfer had not taken place; and

(b)promptly on request from the Developer, the Atlassian Guarantor agrees to do any act and sign any document that is strictly required to restore to the Developer any security interest or guarantee held by it from the Atlassian

Guarantor immediately prior to that payment, obligation, settlement, transaction, conveyance or transfer.

The Developer may apply money paid by the Tenant or the Tenant’s estate, or the Atlassian Guarantor or otherwise towards satisfaction of the Tenant Obligations in the manner it sees fit.

(a)If the Tenant Corporate Structure undergoes a restructure, provided the Tenant has complied with the Agreement for Lease in respect of such restructure, the Tenant may deliver to the Developer a replacement Tenant Parent Company Guarantee on terms identical to this clause 1 from, and duly executed by, the Tenant's ultimate listed parent entity.

(b)With effect on the date the replacement guarantee which complies with the requirements of clause 1.11(a) is delivered to the Developer, the Atlassian Guarantor is released from all future obligations under the Tenant Parent Company Guarantee arising after that date and without limiting the effectiveness of that release, the Developer agrees to promptly execute any documentation reasonably required by the Tenant or the Atlassian Guarantor in order to more fully document that release.

Notwithstanding anything else in the Agreement for Lease or this Deed:

(a)the maximum aggregate liability of the Atlassian Guarantor arising out or in connection with the Agreement for Lease or this Deed:

(1)will not exceed the liability which the Atlassian Guarantor would have had to the Developer in respect of the Tenant Obligations, if the Atlassian Guarantor had been named in the Agreement for Lease as being jointly and severally liable with the Tenant to the Developer; and

(2)is subject to the limitations, exclusions, indemnities, defences which may be available to the Tenant under the Agreement for Lease or any applicable Law;

(b)nothing in the Agreement for Lease or this Deed is intended to render the Atlassian Guarantor liable for the same loss twice for the one breach of the Tenant's obligation to perform the Tenant Obligations under the Agreement for Lease and the Developer may not seek to recover under this clause 1 to the extent that it has recovered for the same loss for the same breach by the Tenant to perform the Tenant Obligations.
