Dear [name],

Letter of Confirmation of Benefit under Tritium Pty Ltd (the Company) Shadow Equity Employee Scheme

We refer to your participation in the Tritium Pty Ltd Shadow Equity Employee Plan (Plan).

As you may be aware, Tritium Holdings Pty Ltd (Tritium Holdings) completed a business combination transaction (Business Combination) with Decarbonization Plus Acquisition Corporation II on 13 January 2022, involving the transfer by shareholders in Tritium Holdings of all their shares in Tritium Holdings to Tritium DCFC Limited (Tritium DCFC) in exchange for ordinary shares in Tritium DCFC (Tritium DCFC Shares). Tritium DCFC Shares commenced trading on The Nasdaq Stock Market LLC (Nasdaq) on 14 January 2022.

It has been calculated that you are entitled to a Benefit (as that term is defined in the Plan) of USD [insert] under the Plan in connection with the completion of the Business Combination. This calculation adopts an Exit Value (as that term is defined in the Plan) of USD 14.7166282, which is the share price that was applied to ordinary shares in Tritium Holdings for the purposes of the Business Combination.

As payment of this Benefit, Tritium DCFC shall issue you [insert number] Tritium DCFC Shares (Specified Shares), which is equal to the aggregate amount of your Benefit divided by USD 10 per Tritium DCFC Share (rounded up to the nearest whole number of shares). The issue price of USD 10 per Tritium DCFC Share used for this calculation represents the price per Tritium DCFC Share at which shareholders in Tritium Holdings acquired Tritium DCFC Shares on completion of the Business Combination.

Attachment A to this letter sets out a summary of tax consequences for the allocation of Tritium DCFC Shares.

[FOR INCLUSION IN LETTER TO AUSTRALIAN PARTICIPANTS (OTHER THAN CURRENT OFFICERS, DIRECTORS & EMPLOYEES): The Specified Shares will be issued to you and reflected in your account with Computershare within 10-20 business days from the date of this letter.

Upon issuance, these Tritium DCFC Shares would be freely tradeable (subject to applicable laws and, if applicable to you, Tritium DCFC’s Insider Trading Compliance Policy (the Policy) a copy of which is available on request). The Policy includes typical restrictions on trading during blackout periods. You should familiarise yourself with these restrictions.

There is currently a blackout period in place pursuant to the Policy, and it is anticipated that this will remain the case until completion of the second full trading day after the public release of earnings data for the fiscal quarter ending 31 March 2022. It is expected that the blackout period will conclude sometime in May 2022.

If you do not deliver a Notice to Tritium DCFC before the conclusion of the blackout period, the Specified Shares will be issued to you and reflected in your account with Computershare shortly after the conclusion of the blackout period. These Tritium DCFC Shares will not be issued subject to any vesting conditions.

The right to acquire the Specified Shares is not subject to any vesting conditions. The right to acquire the Specified Shares is personal and is not transferable (except by force of law upon death or bankruptcy) and will lapse if you purport to transfer your right to acquire the Specified Shares in breach of these terms. In addition, the right to acquire the Specified Shares is intended to operate in accordance with Subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth), such that the right to acquire the Specified Shares is subject to deferred taxation.]
