units (the “IPO”) and (ii) 30 days following the consummation of the Company’s initial business combination
(the “Business Combination”), as such term is defined in the registration statement in connection with the IPO,

the Company, to the Trust Account on the date of the consummation of the closing of the over-allotment option, and concurrently
with the consummation thereof, or on such earlier time and date as may be mutually agreed by the Company and the Subscriber (each
such date, an “Over-Allotment Closing Date”; together with the Initial Closing Date, the “Closing Dates”
and each, a “Closing Date”).

 

1.6. Over-Allotment

of the Subscriber to purchase and pay for the Units as provided herein shall be subject to the satisfaction of the conditions set
forth in Section 5 of the Underwriting Agreement, dated as of the date hereof, by and between the Company and the Subscriber, as
representative of the underwriters named therein (the “Underwriting Agreement”).

 

1.8
Termination. This Agreement and each of the obligations of the undersigned shall be null and void and without effect if the Initial
Closing Date does not occur prior to March 31, 2021.

 

2. Representations and Warranties
of the Subscriber

 

The Subscriber represents and warrants to
the Company that:

 

2.1. No Government Recommendation or Approval.
The Subscriber understands that no federal or state agency has passed upon or made any recommendation or endorsement of the Company
or the Placement of the Securities.

 

2.2. Accredited Investor. The Subscriber
represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities
Act of 1933, as amended (the “Securities Act”), and acknowledges that the sale contemplated hereby is being
made in reliance, among other things, on a private placement exemption to “accredited investors” under the Securities
Act and similar exemptions under state law.

 

2.3. Intent. The Subscriber is purchasing
the Securities solely for investment purposes, for the Subscriber’s own account (and/or for the account or benefit of its
members or affiliates, as permitted, pursuant to the terms hereof), and not with a view to the distribution thereof and the Subscriber
has no present arrangement to sell the Securities to or through any person or entity except as may be permitted hereunder. The
Subscriber shall not engage in hedging transactions with regard to the Securities unless in compliance with the Securities Act.

 

2.4. Restrictions on Transfer. The
Subscriber acknowledges and understands the Units are being offered in a transaction not involving a public offering in the
United States within the meaning of the Securities Act. The Securities have not been registered under the Securities Act and,
if in the future the Subscriber decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be
offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the
Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if
available, or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in
each case in accordance with any applicable securities laws of any state or any other jurisdiction. Notwithstanding the
foregoing, the Subscriber acknowledges and understands the Securities are subject to transfer restrictions as described in
Section 8 hereof. The Subscriber agrees that if any transfer of its Securities or any interest therein is proposed to be
made, as a condition precedent to any such transfer, the Subscriber may be required to deliver to the Company an opinion of
counsel satisfactory to the Company with respect to such transfer. Absent registration or another available exemption from
registration, the Subscriber agrees it will not resell the Securities (unless otherwise permitted pursuant to the terms
hereof). The Subscriber further acknowledges that because the Company is a shell company, Rule 144 may not be available to
the Subscriber for the resale of the Securities until the one year anniversary following consummation of the initial Business
Combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any
contractual transfer restrictions.

  

    2

     

    

 

2.5. Sophisticated Investor.

 

(i) The Subscriber is sophisticated in
financial matters and is able to evaluate the risks and benefits of the investment in the Securities.

 

(ii) The Subscriber is aware that an investment
in the Securities is highly speculative and subject to substantial risks because, among other things, (a) the Securities are subject
to transfer restrictions and have not been registered under the Securities Act and therefore cannot be sold unless subsequently
registered under the Securities Act or an exemption from such registration is available and (b) the Subscriber has waived its redemption
rights with respect to the Securities as set forth in Section 5 hereof, and the Securities held by the Subscriber are not entitled
to, and have no right, interest or claim to any monies held in the Trust Account, and accordingly the Subscriber may suffer a loss
of a portion or all of its investment in the Securities. The Subscriber is able to bear the economic risk of its investment in
the Securities for an indefinite period of time.

 

2.6. Organization and Authority. The Subscriber
is duly organized, validly existing and in good standing under the laws of its state of incorporation or formation and it possesses
all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

 

2.7. Authority. This Agreement has been
validly authorized, executed and delivered by the Subscriber and is a valid and binding agreement enforceable in accordance with
its terms, subject to the general principles of equity and to bankruptcy or other laws affecting the enforcement of creditors’
rights generally.

 

2.8. No Conflicts. The execution, delivery
and performance of this Agreement and the consummation by the Subscriber of the transactions contemplated hereby do not violate,
conflict with or constitute a default under (i) the Subscriber’s charter documents, (ii) any agreement or instrument to which
the Subscriber is a party or (iii) any law, statute, rule or regulation to which the Subscriber is subject, or any agreement, order,
judgment or decree to which the Subscriber is subject.

 

2.9. No Legal Advice from Company. The Subscriber
acknowledges it has had the opportunity to review this Agreement and the transactions contemplated by this Agreement and the other
agreements entered into between the parties hereto with the Subscriber’s own legal counsel and investment and tax advisors.
Except for any statements or representations of the Company made in this Agreement and the other agreements entered into between
the parties hereto, the Subscriber is relying solely on such counsel and advisors and not on any statements or representations
of the Company or any of its representatives or agents for legal, tax or investment advice with respect to this investment, the
transactions contemplated by this Agreement or the securities laws of any jurisdiction.

 

2.10. Reliance on Representations and Warranties.
The Subscriber understands the Units are being offered and sold to the Subscriber in reliance on exemptions from the registration
requirements under the Securities Act, and analogous provisions in the laws and regulations of various states, and that the Company
is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of the
Subscriber set forth in this Agreement in order to determine the applicability of such provisions.

 

2.11. No General Solicitation. The Subscriber
is not subscribing for the Units as a result of or subsequent to any general solicitation or general advertising, including but
not limited to any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media
or broadcast over television or radio, or presented at any seminar or meeting or in a registration statement with respect to the
IPO filed with the Securities and Exchange Commission (“SEC”).

  

    3

     

    

 

2.12. Legend. The Subscriber acknowledges
and agrees the certificates (if any) evidencing each of the Securities shall bear a restrictive legend (the “Legend”),
in form and substance substantially as set forth in Section 4 hereof.

pursuant to Rule 5110(g) of the FINRA Manual, be subject to lock-up for a period of 180 days immediately following the date of
effectiveness or commencement of sales in the IPO, subject to certain limited exceptions to permitted transferees hereunder and
in accordance with FINRA Rule 5110(g)(2). Additionally, the Units and their component parts and the related registration rights
may not be sold, transferred, assigned, pledged or hypothecated during the foregoing 180 day period following the effective date
of the Registration Statement except to any underwriter or selected dealer participating in the IPO and the bona fide officers
or partners of the Subscriber and any such participating underwriter or selected dealer. Additionally, the Units and their component
parts and the related registration rights will not be the subject of any hedging, short sale, derivative, put or call transaction
that would result in the economic disposition of such securities by any person for a period of 180 days immediately following the
date of effectiveness or commencement of sales in the IPO.

or its permitted transferees, as further described in the Warrant Agreement, and (iii) the Units and component parts are being

after the expiration of the lockup described above in clause (i) and they are registered pursuant to the Registration Rights Agreement
or an exemption from registration is available, and the restrictions described above in clause (i) have expired or been waived.

 

8.2 The Subscriber agrees that if the
Company seeks stockholder approval of a Business Combination, then in connection with such Business Combination, the
Subscriber shall (i) vote the Placement Shares owned by it in favor of the Business Combination and (ii) not redeem any

which was approved by shareholders at the 2019 Annual General Meetings. 
 CDP 

Under the rules of the CDP, Mr Henry is entitled to incentive awards calculated by reference to his base salary. For performance at the target level, which
requires Mr Henry to meet the rigorous performance hurdles set by the Board, including delivery of the budget, Mr Henry would receive a cash bonus worth 80 per cent of base salary. For performance at the maximum level, Mr Henry would receive a cash
bonus of 120 per cent of base salary. Two tranches of deferred shares will be awarded to Mr Henry, each to the equivalent value of the actual cash bonus received. These two tranches of deferred shares will vest in two years and five years,
respectively. 
 The grant of deferred shares will be subject to the approval of shareholders where required by applicable listing rules. 

LTIP 
 Long-term incentives are issued under the
terms of the LTIP. The number of LTIP awards allocated will be, on a face value basis, a maximum of 200 per cent of Mr Henry’s base salary, and based on the 12-month average share price and exchange rate up to and including the 30 June
preceding the date of grant. LTIP awards are subject to performance hurdles, which are measured five years after the effective date of the grant. Performance hurdles are not subject to re-testing. 

The performance hurdle requires BHP’s total shareholder return (TSR) over a five-year performance period to be measured against the TSR of a sector peer
group (67 per cent of awards) and the TSR of a global company index (33 per cent of awards). No LTIP awards vest if BHP’s TSR is below the relevant comparator group TSR and the LTIP awards will be forfeited. 25 per cent of LTIP awards vest if
BHP’s TSR is at the relevant comparator group TSR. For all LTIP awards to vest, BHP’s TSR must be at or above the 80th percentile TSR of the relevant comparator group. For performance between the relevant comparator group TSR and the 80th
percentile TSR of the relevant comparator group, vesting occurs on a sliding scale. 
 The grant of LTIP awards will be subject to the approval of
shareholders where required by applicable listing rules. 

 Dividends 

A dividend equivalent payment (DEP) is provided on vested CDP deferred shares and vested LTIP awards. No payment is made in respect of unvested or lapsed CDP
deferred shares and LTIP awards. DEPs are paid in the form of shares. 
 Entitlements on termination 

The rules of the CDP and LTIP and BHP’s remuneration policy provide that where employment is terminated by the resignation of the executive, or by the
Group for cause, Mr Henry is not entitled to any cash incentive for the year in question and all CDP deferred shares or LTIP awards will lapse. 
 If Mr
Henry retires or his employment terminates by mutual agreement: 
  

	•	 	 he may, at the Remuneration Committee’s discretion, be considered for a prorata incentive under the CDP for
the period of service during that year based on performance; 

  

	•	 	 CDP two-year deferred shares would vest in full on the original vesting date; 

 

	•	 	 CDP five-year deferred shares would vest on the original vesting date, with the number of deferred shares to vest
reduced prorata to reflect the period of service; and 

  

	•	 	 he would have a right to retain entitlements to LTIP awards, which would vest on the original vesting date, only
if, and to the extent, the performance hurdles are ultimately met. The number of entitlements Mr Henry would be permitted to retain would be reduced prorata to reflect the period of service. 

Special provisions relate to events described as “uncontrollable” such as death and serious injury. In those circumstances, all of the CDP deferred
shares and LTIP awards that have been awarded but which have not vested or are not exercisable vest immediately to and/or become immediately exercisable by Mr Henry or his estate. 

5. Minimum shareholding requirement (MSR) 
 The Board and
Remuneration Committee has determined that during his term as CEO, Mr Henry will be required to hold BHP securities with a value at least equal to five times one year’s pre-tax (gross) base salary. The value of the securities for the purposes
of this requirement is the market value of the underlying shares. Unvested awards do not qualify. 
 The CEO is expected to grow his holdings to the MSR
from the scheduled vesting of his employee awards over time. The MSR is tested at the time that shares are to be sold. Shares may be sold to satisfy tax obligations arising from the granting, holding, vesting, exercise or sale of the employee awards
or the underlying shares whether the MSR is satisfied at that time or not. 
 Effective 1 July 2020, a two-year post-retirement shareholding requirement for
the CEO will apply from the date of retirement, which will be the lower of the CEO’s MSR or the CEO’s actual shareholding at the date of retirement. 

6. Leave entitlements 
 Mr Henry will be entitled to the
following leave entitlements: 
  

	•	 	 Annual leave – in accordance with applicable Australian law, currently four weeks per annum.

  

	•	 	 Other leave – in accordance with applicable law. 

7. Post-employment restraints 
 Mr Henry will be subject
to non-competition and non-solicitation restraints that operate for 12 months after the cessation of his employment.
