| **Item 1.01** | **Entry Into a Material Definitive Agreement** |

---

On 4 June 2026 (Sydney time), EBR Systems, Inc. (the "***Company***") entered into an underwriting agreement (the "***Underwriting Agreement***") with several underwriters for a fully underwritten A$150.0 million capital raise (the "***Placement***") through the sale of CHESS Depository Interests ("***CDIs***") in the approximate amount of 394.7 million new CDIs ("***New CDIs***"), with every ten (10) CDIs representing one share of the Company's common stock, to institutional investors on the Australian Securities Exchange ("***ASX***") through (i) a fully underwritten institutional placement to institutional and sophisticated investors to raise approximately A$64.4 million (the "***Institutional Placement***"), comprising (a) A$29.4 million institutional placement to institutional and sophisticated investors ("***Tranche 1 Placement***"); and (b) A$35.0 million conditional placement, placed to existing securityholders, subject to securityholder approval ("***Tranche 2 Placement***"), and (ii) a fully underwritten 1 for 2 pro rata accelerated non-renounceable entitlement offer to raise approximately A$85.6 million (the "***Entitlement Offer***").

On 5 June 2026 (Sydney time), the Company successfully completed the Institutional Placement in the amount of approximately A$64.4 million, consisting of the Tranche 1 Placement, which does not require securityholder approval, and the Tranche 2 Placement, which is subject to securityholder approval at a special meeting of the securityholders. The Company also successfully completed the institutional component of the Entitlement Offer (the "***Institutional Entitlement Offer***"), which raised gross proceeds of A$42.0 million, with a take up of approximately A$8.4 million by eligible institutional securityholders and the remainder of the institutional entitlements being approximately A$33.6 million, including New CDIs not taken up by foreign ineligible securityholders, placed to eligible institutional and sophisticated investors as part of the bookbuild.

The Tranche 1 Placement and the Institutional Entitlement Offer is expected to settle on Thursday, 11 June 2026 (Sydney time). The Tranche 2 Placement, which is subject to securityholder approval at a meeting of the securityholders, is expected to settle in August 2026. The portion of the Entitlement Offer allocated for eligible retail securityholders with a registered address in Australia or New Zealand as of the record date of 7:00pm (Sydney time) on Friday, 5 June 2026 (the "***Retail Entitlement Offer***"), will raise a further A$43.6 million and will open on Thursday, 11 June 2026 (Sydney time).

The offer price per New CDI was A$0.38, which represents (i) a 19.1% discount to the last closing price of the Company's CDIs on 3 June 2026 (Sydney time) being A$0.47, (ii) a 15.6% discount to the 5-day VWAP up to 3 June 2026 (Sydney time) being A$0.450, and (iii) a 11.2% discount to the theoretical ex-rights price of A$0.428 per CDI.

Canaccord Genuity (Australia) Limited, E&P Capital Limited and Morgans Corporate Limited acted as joint underwriters, joint lead managers and joint book runners for the Institutional Placement and Entitlement Offer.

The Underwriting Agreement contains customary representations, warranties, and covenants by the parties, including certain indemnification obligations. The representations, warranties, and covenants contained in the Underwriting Agreement were made only for purposes of such agreement and as of specific dates, were solely for the benefit of the parties and are subject to limitations agreed upon in it. Accordingly, the Underwriting Agreement is incorporated herein by reference only to provide investors with information regarding the terms of the Institutional Placement and Entitlement Offer and not to provide investors with any other factual information regarding the Company or its business and should be read in conjunction with the disclosures in the Company's periodic reports and other filings with the Securities and Exchange Commission.

The foregoing description of the Underwriting Agreement is not complete and is qualified in its entirety by reference to the full text of the Underwriting Agreement, which is filed herewith as Exhibit 10.1 and incorporated herein by reference in its entirety.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Underwriters and their respective Affiliates and any proposed sub-underwriters may bid and subscribe

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.4 Time for and conditions of settlement

The Institutional Offer CDIs must be offered on terms that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) settlement is to occur on the Institutional Offer Settlement Date; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) those Institutional Investors and Institutional CDI Holders who irrevocably agree to subscribe for Institutional
Offer CDIs:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) must sign a Confirmation Letter; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) will have no further obligation to the Company to subscribe for those Institutional Offer CDIs if the
Underwriters terminate their obligations under this Agreement on or before the Institutional Offer Settlement Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.5 Adjustment

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Company will, to the extent reasonably required by the Underwriters following consultation with
the Company, take all reasonable actions to adjust the number of Entitlement Offer CDIs allocated to any Institutional CDI Holder or Excluded
Institutional CDI Holder that they would have been otherwise entitled to subscribe for if eligible under the Institutional Offer, if at
any stage it appears that the Entitlement Offer CDIs attributed to that Institutional CDI Holder or would have been attributed to an Excluded
Institutional CDI Holder were based on incorrect information regarding the number of CDIs held (or taken under the terms of the Listing
Rules to be held) by or by nominees for that Institutional CDI Holder or Excluded Institutional CDI Holder as at 7.00pm on the Record
Date. Following any such adjustment the number of Offer CDIs allocated to that Institutional CDI Holder or which would have been attributed
to that Excluded Institutional CDI Holder, will be taken to be the adjusted number for the purposes of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) If appropriate adjustments are not made under clause 4.5(a), or if reconciliation issues arise, the
Underwriters may require such steps as they reasonably specify to be taken to address those matters, including, at their discretion, requiring
that Retail Offer Shortfall CDIs (or CDIs which would become Retail Offer Shortfall CDIs but for the application of this clause and assuming
Valid Applications from Retail CDI Holders in excess of their Entitlements are not satisfied) be issued to Institutional CDI Holders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.6 Additional placement

If appropriate adjustments are unable to be made under clause 4.5, or if reconciliation issues arise, the Underwriters may on behalf of the Company place to Institutional CDI Holders or Retail CDI Holders (either directly or via the Underwriters) up to such number of CDIs as is permitted by the Listing Rules, the Corporations Act and the Constitution as are necessary to ensure that those CDI Holders (or beneficial owners of CDIs) receive their pro rata entitlement under the Entitlement Offer. Without limiting clause 16.9, the Company agrees to do everything reasonably necessary to give effect to any placement of CDIs by the Underwriters (on behalf of the Company) under this clause 4.6.

to an Institutional CDI Holder or an Institutional Investor proposed by the Underwriters where such refusal would result in or increase
a shortfall (provided however no allocation may be made to an Excluded Institutional CDI Holder or to an Institutional Investor in a jurisdiction
in which the Institutional Offer is not being extended).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Notwithstanding any other provision of this Agreement, the Underwriters (acting reasonably), in consultation
with the Company, may determine to treat a person who may be an Institutional CDI Holder or a Retail CDI Holder as an Excluded CDI Holder

the manner, and by the time, required by the Underwriters.

the Institutional Offer Proceeds to the Company on or before 3.00pm on the Institutional Offer Settlement Date but due to a non-ordinary
course delay in the banking system such funds have not been credited to the Company's bank account by that time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.10 Settlement support

The Company appoints Canaccord or its Affiliate as the Company's agent in relation to the settlement of the Institutional Offer Acceptance CDIs and Institutional Offer Shortfall CDIs through the allocation interest CHESS DvP settlement process. The Company must do, or cause the Registry to do, anything required on its own part, or the Registry's part, to facilitate the CHESS DvP settlement on the Institutional Offer Settlement Date.

remaining Underwriter (the **Remaining Underwriters**) may elect (but is not obliged to) by notice in writing to the Company within
three Business Days of the Remaining Underwriters becoming aware of the termination by the Terminating Underwriter to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) take up all the rights (including the right to be paid all amounts which, at the date of termination,
are not yet payable to or accrued by the Terminating Joint lead Manager) and perform the remaining obligations of the Terminating Underwriter
under this Agreement in equal proportions; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) with the prior written consent of the Company (such consent not to be unreasonably withheld or delayed)
and in agreement with the other Remaining Underwriter, nominate a proposed replacement joint lead manager for the Terminating Underwriter
(the **Replacement Underwriter**), to take up all the rights and assume all the obligations of the Terminating Underwriter under this

Underwriters to assume that Terminating Underwriter's underwriting obligations unless a Remaining Underwriter elects to do so pursuant
to clause 11.9(b).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) If one or both of the Remaining Underwriters elect to assume all the rights and obligations of the
Terminating Underwriter or one or both of the Remaining Underwriters do not nominate a Replacement Underwriter (with the provision of
an executed accession deed by the proposed Replacement Underwriter, the Company and the Remaining Underwriters) in accordance with clause
11.9(b) within the period referred to in clause 11.9(b), then the Remaining Underwriters are deemed to have terminated their remaining
obligations under this Agreement on the expiry of that period.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) If one or both of the Remaining Underwriters give notice under clause 11.9(b)(1) the Remaining Underwriter
or Underwriters (as the case may be) will take up all the rights and assume the obligations of the Terminating Underwriter under this
Agreement, then the Remaining Underwriter or Underwriters (as the case may be), in addition to the fees to which they are entitled under
clause 10.1, will also be entitled to a proportion of the relevant fees that would have been payable to the Terminating Underwriter under
clause 10.1 if they had not terminated this Agreement, which is equivalent to the proportionate percentage share of the rights and obligations
which that Underwriter has elected to assume (such fees not to include any fees already owed to, or accrued by, or otherwise entitled
to be received by the Terminating Underwriter in connection with this Agreement or any fees due to any Replacement Underwriter under clause
11.9(f)).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) If the Remaining Underwriters give notice under clause 11.9(b)(2) nominating a Replacement Underwriter
under this Agreement and an appropriate accession deed is executed by the Replacement Underwriter, the Company and the Remaining Underwriters,
then the Replacement Underwriter will be entitled to the relevant part of the fees that would have been payable to the Terminating Underwriter
under clause 10.1 if they had not terminated this Agreement (such fees not to include any fees already owed to, or accrued by, or otherwise
entitled to be received by the Terminating Underwriter or any fees due to the Remaining Underwriters under clause 11.9(e) in connection
with this Agreement).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) Any provision of this Agreement which refers to the consent of the Underwriters must, following termination
by the Terminating Underwriter, be interpreted as referring solely to the Remaining Underwriters or, if applicable the Remaining Underwriters
and the Replacement Underwriter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) Without limiting this clause 11.9, nothing contained in clause 11 will prejudice or nullify any claim
for damages or other right which an Underwriter or any other Indemnified Party may have against the Company for or arising out of any
breach of undertaking, warranty or representation or failure to observe or perform an obligation under this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) If all Underwriters terminate on or before the allotment and issue of the Institutional CDIs referred
to in clause 3.10, the Underwriters may notify applicants for Offer CDIs that they have no obligations or rights to subscribe for such
Offer CDIs and if all the Underwriters have terminated after allotment and issue of the Institutional CDIs referred to in clause 3.10
but prior to the allotment and issue of Retail CDIs referred to in clause 5,
the Underwriters may notify any sub-underwriters, co-managers and brokers to the Offer that they have no further obligations or rights
to subscribe for Offer CDIs under the Retail Offer (if any).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) This clause 11.9 may apply on more than one occasion, including if there is more than one termination
by an Underwriter.

be illegal, void or unenforceable under applicable law, or which constitutes a criminal penalty or criminal fine which an Indemnified
Party is required to pay for any contravention by it of the Corporations Act or any applicable law, except to the extent it is contributed
by a Group Member.

The failure of an Indemnified Party to notify the Company pursuant to clause 12.3 will not release the Company from any obligation or liability which it may have pursuant to this Agreement except that such liability will be reduced to the extent to which the amount the subject of the indemnity under clause 12.1 has materially increased, directly as a result of the failure to so notify.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.5 Benefits of indemnity

Each Indemnified Party, whether or not a party to this Agreement, will be entitled to the benefit of the provisions in this clause 12 and this clause 12 may be enforced on that Indemnified Party's behalf by the relevant Underwriter (which holds the benefit of the relevant provisions on trust for the other Indemnified Parties).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.6 Preservation of rights

Subject to clause 12.2, the rights of an Indemnified Party under this Agreement will not in any way be prejudiced or affected by:

If for any reason the indemnities contained in this clause 12 are unavailable or insufficient to fully indemnify any Indemnified Party against any Indemnified Claim (other than as a result of the operation of clause 12.2) then the Company and the Indemnified Party agree to contribute to the relevant Indemnified Claim in accordance with clauses 12.13 to 12.15 in all cases to the maximum extent allowed by law.

on its own behalf and on trust for its associated Indemnified Parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;12.20 Relevant Limitation

Loss will be recoverable by the Company from that Underwriter will:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) be limited so as to be in proportion to that Underwriter's contribution to the overall fault for
such Loss, as agreed between that Underwriter and the Company or, in the absence of agreement, as finally judicially determined by a court
of competent jurisdiction; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) be no more than it would have been had any Relevant Limitation not existed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Where any damage or Loss is suffered by an Underwriter arising from a liability which, but for a Relevant
Limitation or any limitation on the extent to which that Underwriter may claim against a third party or parties which binds that Underwriter,
would be a joint or joint and several liability of that Underwriter with any third party, the Company's indemnity under clause 12.1
will cover any amount which that Underwriter is unable to recover from the third party or third parties because of the Relevant Limitation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Company acknowledges that the degree to which the Underwriters may rely on the work of any such
third party (if any) will be unaffected by any Relevant Limitation.
