Subject to clauses 8(i) and 8(j), Vast Parent must, no later than 2 Business Days following the expiry of the Postponement Period, issue or transfer (as applicable) the Exchange Shares in respect of which the Purchaser has given written notice to exchange under clause 8(a) to which the Postponement Period relates.

(f)

Vast Parent must issue or transfer the Exchange Shares to the Purchaser free and clear of any Security Interest (except for any Security Interest arising under U.S. or Australian federal and state securities laws) or Security Interest or right of any third party, escrow or holding lock.

(g)

This clause 8 survives termination or expiration of this Agreement and is not prejudiced by the occurrence of an Event of Default (as such term is defined in the Promissory Note) caused by HoldCo or Vast Parent or acceleration of the Promissory Note.

(h)

Upon and following the announcement of the entry of Vast Parent and/or its shareholders or securityholders into definitive, binding documentation to implement a Change of Control (as defined in the Business Combination Agreement) (a CoC Agreement), at the election of the Purchaser, all principal amount of and interest on the Promissory Note then outstanding will become exchangeable into Exchange Shares to be issued to the Purchaser. The Purchaser will be entitled to make such election within a period of 30 days after the announcement of the entry into the CoC Agreement, after which time the Purchaser may only make such election if agreed in or permitted by or approved under the CoC Agreement and each Company Party must promptly use best endeavours and do all things necessary to enable the Purchaser to make such election. Each Company Party must ensure that Vast Parent announces the entry of Vast Parent and/or its shareholders or securityholders into a CoC Agreement as soon as practicable after such entry and in accordance with all applicable laws and the rules and regulations of Vast Parent’s stock exchange.

(i)

If any issue or transfer of Exchange Shares to the Purchaser under this clause 8 requires the prior obtaining of any Authorisation in order to comply with any applicable law or regulation or rules of any recognized securities exchange, Vast Parent must promptly use best endeavours and do all things necessary to obtain such Authorisation. If Vast Parent, having complied with its obligations under this clause 8(i) and having exhausted all reasonable means of obtaining such Authorisation, is refused or is otherwise unable to obtain such Authorisation and is thereby unable to issue or transfer (as applicable) the relevant Exchange Shares without Vast Parent breaching any applicable law or regulation or rules of any recognized securities exchange, then Vast Parent must promptly pay to the Purchaser by wire transfer of immediately available funds the amount of principal amount of and interest on the Promissory Note which the Purchaser was exchanging for the relevant Exchange Shares under clause 8(a), instead of issuing or transferring (as applicable) those Exchange Shares to the Purchaser. For the avoidance of doubt this clause 8(i) does not apply to any Authorisation required to be obtained by the Purchaser in order for the Purchaser to comply with any applicable law to issued or transferred (as applicable) the Exchange Shares, including without out limitation, under the Foreign Acquisitions and Takeovers Act 1975 (Cth).

page | 24

(j)

Despite any other provision of this Agreement or the Promissory Note, the Purchaser's right to require the issue or transfer of Exchange Shares under this clause ‎‎8 or the Promissory Note is subject to and conditional upon the Purchaser obtaining any Authorisation necessary for the Purchaser to comply with The Foreign Acquisitions and Takeovers Act 1975 (Cth) in respect of such issue or transfer.

If, in the period commencing on the date of this Agreement until the Promissory Note is repaid in full, Vast Parent or any of its Subsidiaries enters into an agreement pursuant to which Qantas and/or Airbus will pay or contribute funds to Vast Parent or a Subsidiary, the terms of such agreement or any amendment to such agreement must be on substantially the same and no more favourable terms to Qantas and/ or Airbus than the terms of this Agreement or the Promissory Note, in respect of any of the following (MFN Terms):

	(i)	security or priority;

	(ii)	duration; or

	(iii)	interest rate,

and if any of the MFN Terms in such agreement or any amendment to such agreement with Qantas and/or Airbus is more favourable to Qantas and/ or Airbus than the MFN Terms of this Agreement or the Promissory Note, then the corresponding MFN Terms of this Agreement and/or the Promissory Note (as applicable) shall be automatically amended to match such Qantas and/or Airbus terms, which will be applied on a dollar-for-dollar basis (to the extent possible).

(b)

If Vast Parent or any of its Subsidiaries proposes to enter into an agreement with Qantas and/or Airbus, Vast Parent or HoldCo must give the Purchaser written notice setting out the details of the proposed arrangement at least 5 Business Days before entering into definitive documents with Qantas and/or Airbus in respect of such arrangement and/or receiving such funding.

(c)

If Vast Parent and/or a Subsidiary enters into an agreement with Qantas and/or Airbus on more favourable MFN Terms to Qantas and/ or Airbus than the MFN Terms of this Agreement and/or the Promissory Note but the funding from Qantas and/or Airbus never occurs under such agreement, the MFN Terms in this Agreement and/or the Promissory Note (as applicable) will revert back to the prior terms as if this Agreement and/or the Promissory Note (as applicable) was never amended in respect of such agreement.

(e)

If Vast Parent and/or any Subsidiary proposes to enter into New Strategic Commitments and plans to repay all or a portion of the Backstop Loan Agreement, Vast Parent and/or HoldCo must give the Purchaser written notice setting out the details of the proposed arrangement at least 5 Business Days before entering into definitive documents regarding the New Strategic Commitments and/or receiving such funding.

(f)

If Vast Parent and/or a Subsidiary enters into an agreement on more favourable MFN Terms to a third party strategic investor than the MFN Terms of this Agreement and/or the Promissory Note but the funding from the third party strategic investor never occurs under such agreement or no portion of such funding is used to repay the Backstop Loan Agreement, the MFN Terms in this Agreement and/or the Promissory Note (as applicable) will revert back to the prior terms as if this Agreement and/or the Promissory Note (as applicable) was never amended in respect of such agreement.

(g)

Notwithstanding the foregoing, if at any time on and from the date of this Agreement until the Promissory Note is repaid in full, Vast Parent or any of its Subsidiaries enters into an agreement pursuant to which Qantas and/or Airbus has the right to purchase Vast Shares or exchange, convert or exercise any security into Vast Shares at a price per share less than the Exchange Price in effect immediately prior to such purchase, exchange, conversion or exercise, the Exchange Price shall automatically adjust to the lowest price per share at which Qantas or Airbus has the right to purchase or exchange, convert or exercise a security into Vast Shares, which will be applied on a dollar-for-dollar basis (to the extent possible).
