13.

ENTIRE AGREEMENT AND REMEDIES

13.1

This Agreement and the other Transaction Documents together set out the entire agreement between the parties relating to the sale and purchase of the Shares and, save to the extent expressly set out in this Agreement or any other Transaction Document, supersede and extinguish any prior drafts, agreements, undertakings, representations, warranties, promises, assurances and arrangements of any nature whatsoever, whether or not in writing, relating thereto. This Clause shall not exclude any liability for or remedy in respect of fraudulent misrepresentation.

13.2

15.

WAIVER AND VARIATION

15.1

A failure or delay by a party to exercise any right or remedy provided under this Agreement or by Law, whether by conduct or otherwise, shall not constitute a waiver of that or any other right or remedy, nor shall it preclude or restrict any further exercise of that or any other right or remedy. No single or partial exercise of any right or remedy provided under this Agreement or by Law, whether by conduct or otherwise, shall preclude or restrict the further exercise of that or any other right or remedy.

15.2

A waiver of any right or remedy under this Agreement shall only be effective if given in writing and shall not be deemed a waiver of any subsequent breach or default.

15.3

No variation or amendment of this Agreement shall be valid unless it is in writing and duly executed by or on behalf of all of the parties to this Agreement. Unless expressly agreed, no variation or amendment shall constitute a general waiver of any provision of this Agreement, nor shall it affect any rights or obligations under or pursuant to this Agreement which have already accrued up to the date of variation or amendment and the rights and obligations under or pursuant to this Agreement shall remain in full force and effect except and only to the extent that they are varied or amended.

16.

INVALIDITY

Where any provision of this Agreement is or becomes illegal, invalid or unenforceable in any respect under the Laws of any jurisdiction then such provision shall be deemed to be severed from this Agreement and, if possible, replaced with a lawful provision which, as closely as possible, gives effect to the intention of the parties under this Agreement and, where permissible, that shall not affect or impair the legality, validity or enforceability in that, or any other, jurisdiction of any other provision of this Agreement.

17.

ASSIGNMENT

17.1

Except as provided in this Clause 17 or as the parties specifically agree in writing, no person shall assign, transfer, charge or otherwise deal with all or any of its rights under this Agreement nor grant, declare, create or dispose of any right or interest in it.

17.2

(c)

any bank or financial institution lending money or making other banking facilities available to the Purchaser, by way of security, or any refinancing thereof.

Any such person to whom an assignment is made under this Clause 17.2 may itself make an assignment as if it were the Purchaser under this Clause 17.2.

the Purchaser will remain liable for any obligations under this Agreement.

(3) The Manager may be required to bear the economic risk of the Investment for an indefinite period of time because the Investment has not been registered for sale under the Securities Act and therefore cannot be sold or otherwise transferred unless either the Investment is subsequently registered under the Securities Act, or an exemption from such registration is available, and the Investment cannot be sold or otherwise transferred unless it is registered under applicable state securities or an exemption from such registration is available.

(4) The Manager’s right to transfer the Investment will be restricted by the terms of the Stockholders Agreement.

(5) The Manager is not acquiring the Investment as a result of any advertisement, article, notice or other communication published in any newspaper, magazine or similar media or broadcast over television or radio, any seminar or meeting, or any solicitation of a subscription by a person not previously known to the Manager in connection with investments in securities generally.

(6) The Manager is an “Accredited Investor” (as defined in Rule 501 promulgated under the Securities Act).

(7) The Manager has been furnished all materials relating to CPHAC and the Investment that the Manager has requested and has been afforded the opportunity to ask questions and receive answers concerning the terms and conditions of the offering and obtain any additional information regarding the Investment which CPHAC possesses or can acquire without unreasonable effort or expense.

(8) Representatives of CPHAC have answered all inquiries that the Manager has made of them concerning CPHAC and their Affiliates, or any other matters relating to the formation and proposed operation of CPHAC and the offering and sale of the Investment. The Manager acknowledges that none of CPHAC or any Affiliate thereof has rendered or will render any investment advice or securities valuation advice to the Manager and that the Manager is neither subscribing for nor acquiring the Investment in reliance upon, or with the expectation of, any such advice.

(9) The Manager has not been furnished any offering literature with respect to the Investment or CPHAC. In addition, no representations or warranties have been made to the Manager with respect to the Investment or CPHAC, and the Manager has not relied upon any such representation or warranty in making this subscription.

(10) The Manager has such knowledge and experience in financial and business matters that the Manager is capable of evaluating the merits and risks of the Investment and of making an informed investment decision with respect thereto.

(11) The Manager is relying on his or her own investigation and analysis in making the Investment and has consulted his or her own legal, tax, financial and accounting advisors to determine the merits and risks thereof.

(12) The Manager is not relying on any due diligence investigation that Industrea Acquisition Corp. and/or its Affiliates and advisors may have conducted with respect to CPHI or any of its Affiliates. Except to the extent set forth in this Deed, none of CPHAC, Industrea and/or its Affiliates, or any of their respective current or former equity holders, members, managers, partners, officers, directors, employees, affiliates or advisors (i) makes any representation or warranty as to the information provided to the Manager regarding the Investment nor represents or warrants such information as being all-inclusive or to contain all information that may be desirable or required in order to properly evaluate the Investment or (ii) will have any liability with respect to any use or reliance upon any of the Information.

(13) The Manager is able to bear the economic risks of the Investment and consequently, without limiting the generality of the foregoing, is able to hold the Investment for an indefinite period of time and has sufficient net worth to sustain a loss of the entire Investment in the event such loss should occur.

(14) The Manager is acquiring the Investment for the Manager’s own account as principal for investment purposes and not with a view to the distribution or sale thereof, subject to any requirement of law that its property at all times be within its control.

(15) The Manager recognises that CPHAC’s issuance and sale of the Investment to the Manager will be based upon the Manager’s representations, warranties and covenants set forth above. All representations, warranties and covenants contained in this Deed (including this Schedule 10) shall survive the consummation of the transactions set forth therein.

(16) The Manager acknowledges and agrees that the following restrictions and limitations are applicable to any resale or other transfer of the Investment:

A. The Investment shall not be sold or otherwise transferred to the extent such sale or transfer is restricted by the Stockholders Agreement and, if so restricted, may only be sold or transferred if the applicable provisions set forth in the Stockholders Agreement are satisfied.

B. The Investment shall not be sold or otherwise transferred unless in compliance with all applicable securities laws.
