	2.	Amendment to the Deed of Undertaking 

  

	2.1	The Offeror has today entered into a deed amending the Deed of Undertaking (the “Amendment Deed”) with World Sharehold Limited (the “Selling
Shareholder”) and its shareholders, namely, Mr. Wang Wei Yao and Mr. Shao Jian Jun (collectively, the Selling Shareholder, Mr. Wang Wei Yao and Mr. Shao Jian Jun shall be referred to as the “Sellers”) to
amend the terms of the Selling Shareholder’s investment in CHAC Shares and the Selling Shareholder’s entitlement to receive additional new CHAC Shares as set out in paragraph 5.1 of the Pre-Conditional Offer Announcement.










	2.2	Pursuant to the terms of the Amendment Deed, the Deed of Undertaking has been amended such that: 

  

	 	2.2.1	the Sellers undertake to: 

  

	 	(i)	take, and to the extent lawfully permissible, cause their representatives to take all reasonable and lawfully permissible steps to encourage and/or to cause Newco to lawfully
declare and pay a cash dividend of USD$0.50 per issued share of Newco (the “Newco Cash Dividend”) to the holders thereof, immediately after the Closing; and

	 	(i)	At Closing, the Offeror will deliver a convertible promissory note (the “CHAC Note”) to the Selling Shareholder as payment for the aggregate Offer Price (defined
below) due for the Shares tendered by the Selling Shareholder. 

  

	 	(ii)	Immediately after Closing, the Offeror will issue and sell to the Selling Shareholder, and the Selling Shareholder will purchase from the Offeror, the initial new CHAC Shares by
delivering the CHAC Note to the Offeror as payment therefore. 

  

	 	(iii)	Under the CHAC Note, the Offeror will issue to the Selling Shareholder a minimum of 19,900,000 initial new CHAC Shares, amounting to approximately 54 per cent. of the enlarged
issued share capital of the Offeror (assuming there are no redemptions of CHAC Shares and the equity equivalent value of all its outstanding warrants is determined by the Treasury Stock Method). 

  

	 	(iv)	Under the CHAC Note, the Selling Shareholder will also be eligible to receive, without any additional consideration being due therefore, up to a maximum of 15,765,000 additional new
CHAC Shares consisting of: 

  

	 	(a)	3,500,000 additional new CHAC Shares to be issued to the Selling Shareholder upon satisfaction of Common Stock Earnout Target I; 

  

	 	(b)	3,500,000 additional new CHAC Shares to be issued to the Selling Shareholder upon satisfaction of Common Stock Earnout Target II; and 

  

	 	(c)	up to 8,765,000 additional new CHAC Shares to be issued to the Selling Shareholder upon satisfaction of Common Stock Earnout Target III, 

 provided that the number of CHAC Shares to be issued to the Selling Shareholder upon satisfaction of Common Stock Earnout Target III and

 “Common Stock Earnout Target I” means the closing sale price for the regular Trading
Day (as defined in the Deed of Undertaking) (without considering after hours or other trading outside regular trading session hours) of the Common Stock on the applicable Trading Market (as defined in the Deed of Undertaking) (or, if no closing
price is reported, the last reported sale price during that regular Trading Day) for any 20 days within any 30 day trading period beginning 90 days after the Closing Date (as defined in the Deed of Undertaking) exceeds US$12.50 per share.

cent. of the enlarged issued share capital of the Offeror (assuming there are no redemptions of CHAC Shares and the equity equivalent value of all its outstanding warrants is determined by the Treasury Stock Method), in one or more issuances. The
initial new CHAC Shares will be issued to the Selling Shareholder at US$8 for each CHAC Share. Upon satisfaction of each relevant Common Stock Earnout Target, the additional new CHAC Shares will be issued to the Selling Shareholder at no cost.


  

	2.3	Certain founders of CHAC (“Founders”) have entered into an agreement (the “Founders’ Agreement”), pursuant to which, each Founder
agreed that, subject to the consummation of the Merger, the shares of common stock in CHAC beneficially owned by such Founders will be converted into warrants (the “New Founder Warrants”) to purchase an equal number of shares of
Newco. Each Founder Warrant will be immediately exercisable when the closing sale price of Newco’s shares exceeds US$13.50 per share for any 20 days within any 30 day trading period beginning 90 days after the Closing Date.

 Capitalized terms used herein but not defined shall have the meanings assigned thereto in the Deed
of Undertaking. 
 I. Maximum Number of Offeror Shares: 35,665,000, consisting of Initial Offeror Shares and Additional Offeror Shares. The
Selling Shareholder will receive the maximum number of Offeror Shares if all three (3) Common Stock Earnout Targets are met.

of Offeror Shares: 19,900,000, consisting solely of Initial Offeror Shares. 
 III. Number of Initial Offeror Shares and Additional Offeror
Shares: The number of Initial Offeror Shares and Additional Offeror Shares will vary depending upon the cash offer price per issued share of the Company (“Company Share”) offered to the Public Shareholders. The higher the cash
offer price per Company Share, the more Initial Offeror Shares the Selling Shareholder shall be entitled to receive upon exchange of the CHAC Note. The maximum number of Initial Offeror Shares is 23,665,000. 
 IV. Calculation of Initial Offeror Shares: The number of Initial Offeror Shares shall be calculated as follows:

Consideration”); 
 Step 2: BWPM SGD Consideration multiplied by the Average Exchange Rate (“BWPM USD
Consideration”); and 
 Step 3: BWPM USD Consideration divided by Per Offeror Share Purchase Price, and rounded down to the
nearest one Share. 
 For example, assuming (a) the Selling Shareholder holds 309,697,000 Shares, (b) a S$0.75 cash offer price per Company Share,
(c) an Average Exchange Rate of 0.73524 and (d) a USD$8.00 Per Offeror Share Purchase Price, the number of Initial Offeror Shares to be issued to the Selling Shareholder at Closing is 21,347,027.

II, 3,500,000 Additional Offeror Shares; and 
 C. Upon satisfaction of Common Stock Earnout Target III, up to 8,765,000 Additional Offeror
Shares, which shall be calculated as follows: 8,765,000 minus the number of Initial Offeror Shares in excess of 19,900,000.

 Dear Sirs 
 [    ] as the survivor to the merger of [NewCo] and China Holdings Acquisition Corp. Company No. [    ] (the “Company”) 
  

	1.	We are lawyers qualified to practise in the British Virgin Islands and have been asked to advise in connection with: 

  

	 	(i)	a deed of undertaking dated [—] 2008 (the “Deed”) made by World Sharehold Limited (the “Selling Shareholder”),
Wang Wei Yao and Shao Jian Jun, on the one hand (collectively, the “Sellers”), and China Holdings Acquisition Corp. (“CHAC”), on the other hand, pursuant to which CHAC agreed to make an offer to acquire all the
issued shares in Bright World Machinery Limited (“Bright World”), and Selling Shareholder agreed to accept the offer in respect of all issued shares of Bright World held by the Selling Shareholder, payment for which was made inter
alia by the issue by CHAC to the Selling Shareholder of a convertible promissory note; 

  

	 	(ii)	an amendment to the Deed dated [—] 2008 made by the Sellers and CHAC, pursuant to which certain amendments were made to the Deed among them, the
revision of the terms under which up to a maximum of 15,765,000 shares in the Company (the “Additional Shares”) would be issued to the Selling Shareholder (the “Amendment to Deed”; and 

  

	 	(iii)	a convertible promissory note dated [    ] (the “Note”) issued by the Company in its capacity as the survivor to the merger of CHAC and [NewCo]
in favour of the Selling Shareholder and convertible into up to 23,665,000 initial shares of the Company (the “Initial Offeror Shares”), provided, however, that the total number of shares of the Company to be issued in accordance
with the terms of the Note will not exceed 35,665,000, 

 (the Deed, Amendment to the Deed and the Note are together referred to
as the “Documents”). 
  

 1 








 This opinion is given pursuant to clause 1.6.2(ii) of the Deed. Capitalised terms defined in the Deed, as
amended by the Amendment to the Deed, have the same meaning in this opinion unless otherwise defined in this opinion. 
  

	2.	For the purpose of this opinion, we have examined the following documents and records: 

  


	 	(a)	A copy of the executed Documents; 

  

	 	(b)	a copy of the Memorandum and Articles of Association and Certificate of Incorporation of the Company and the articles of merger with the plan of merger annexed obtained from the
British Virgin Islands Registry of Corporate Affairs on [—]; 

  

					
	 (c)
	  	(i)	  	a copy of the [unanimous written resolutions]/[minutes of a meeting of the directors of the Company containing unanimous resolutions] of the directors of the Company dated [—] approving the Company’s merger with China Holdings Acquisition Corp. and its entry into and execution of the plan of merger and articles of merger;
			
		  	(ii)	  	a copy of the [unanimous written resolutions]/[minutes of a meeting of the directors of the Company containing unanimous resolutions] of the directors of the Company dated [—] approving the Company’s entry into and execution of the Note and the issue of the Initial Offer Shares and the Additional Shares
		
		  	 (the “Board Resolutions”);


  

	 	(d)	a copy of the [unanimous written resolutions]/[minutes of a meeting of the shareholders of the Company containing unanimous resolutions] of the shareholders of the Company dated
[—] approving the Company’s merger with China Holdings Acquisition Corp. and its entry into and execution of the plan of merger and articles of merger (the “Shareholders Resolutions”);


  

	 	(e)	a copy of a certificate issued by a director of the Company dated [                ] 2008 (the
“Director’s Certificate”); and 

  

	 	(f)	information revealed by our searches of: 

  

	 	(i)	the records and information certified by [—], the registered agent of the Company, on [—] of the statutory
documents and records maintained by the Company at its registered office; 

  

	 	(ii)	the public records of the Company on file and available for inspection at the Registry of Corporate Affairs, Road Town, Tortola, British Virgin Islands on [—]; and 

  

	 	(iii)	the records of proceedings on file with, and available for inspection on [—] at the High Court of Justice, British Virgin Islands,


 (the “Searches”). 
 The above are the only documents or records we have examined and the only enquiries we have carried out. In particular we have made no enquiries as to matters of fact other than the Searches. 
  

 2 









	3.	For the purposes of this opinion we have assumed without further enquiry: 

  

	 	(a)	the authenticity of all documents submitted to us as originals, the conformity with the originals of all documents submitted to us as copies and the authenticity of such originals;


  

	 	(b)	the genuineness of all signatures and seals; 

  

	 	(c)	the accuracy and completeness of all corporate minutes, resolutions, certificates and records which we have seen; 

  

	 	(d)	that the information indicated by the Searches is and remains true and correct; 

  

	 	(e)	the accuracy of any and all representations of fact expressed in or implied by the documents we have examined; 

  

	 	(f)	that the Documents constitute valid, legally binding and enforceable obligations of the Company under the laws of the State of Delaware in the United States of America by which law
they are expressed to be governed; 

  

	 	(g)	that no matters arising under any foreign law will affect the views expressed in this opinion; 

  

	 	(h)	that no director of the Company has a financial interest in or other relationship to a party to the transaction contemplated by the Documents except as expressly disclosed in the
Board Resolutions; 

  

	 	(i)	that the Board Resolutions and the Shareholders Resolutions remain in full force and effect; and 

  

	 	(j)	that no resolution of the members of the Company has been passed limiting the powers of the directors. 

  

	4.	Based on the foregoing, and subject to the qualifications expressed below, our opinion is as follows: 

  

	 	(a)	Existence and Good Standing. The Company is a company duly registered with limited liability for an unlimited duration under the BVI Business Companies Act (No 16 of 2004),
and is validly existing and in good standing under the laws of the British Virgin Islands. It is a separate legal entity and is subject to suit in its own name. 

  

	 	(b)	Merger. The merger of the Company with China Holdings Acquisition Corp. was duly authorised by the Company and is valid and effective under British Virgin Islands law.


  

	 	(c)	Capacity and Power. The Company has full capacity to execute the Note and to perform its obligations under the Documents and the Company has taken all necessary action to
execute the Note and to authorise its exercise of its rights and the performance of its obligations under the Documents. 

  

	 	(d)	Due Execution. The Documents have been duly executed for and on behalf of the Company. 

  

	 	(e)	Valid and Binding. The Documents will be treated by the courts of the British Virgin Islands as the legally binding, valid and enforceable obligations of the Company.


  

	 	(f)	Consents. No consents or authorisations of any government or official authorities of or in the British Virgin Islands are necessary for the grant and execution of the Note by
the Company the performance by the Company of its obligations and the exercise of its rights pursuant to the Documents and the issue of the Initial Offer Shares or the Additional Shares. 

  

 3 









	 	(g)	Non-conflict. The performance by the Company of its obligations and the exercise of any of its rights pursuant to the Documents do not and will not conflict with:


  

	 	(i)	any law or regulation of the British Virgin Islands; or 

  

	 	(ii)	the Memorandum and Articles of Association of the Company. 

  

	 	(h)	Stamp Duty. No stamp duties or similar documentary taxes imposed by or in the British Virgin Islands are payable in respect of the Documents or the issue of the Initial Offer
Shares or the Additional Shares. 

  

	 	(i)	Initial Offer Shares. The Initial Offer Shares, when issued against payment therefor in accordance with the provisions of the Documents will be duly and validly issued fully
paid and non-assessable and, to our knowledge, on the basis of the Director’s Certificate, free and clear of all liens, charges, restrictions and encumbrances imposed by or through the Company except as set forth in the Documents.


  

	 	(j)	Additional Shares. The Additional Shares, when issued in exchange for the consideration set forth in the Documents and upon satisfaction of the Common Stock Earnout Targets,
will be duly and validly issued fully paid and non-assessable and, to our knowledge, on the basis of the Director’s Certificate, free and clear of all liens, charges, restrictions and encumbrances imposed by or through the Company except as set
forth in the Documents. 

  

	 	(k)	Cash Dividend. For so long as the directors of the Company are satisfied, on reasonable grounds, that, immediately after the dividend distribution, the value of the
Company’s assets will exceed its liabilities and the Company will be able to pay its debts as they fall due (in accordance with Article 18 of the Company’s Articles of Association), the declaration of a cash dividend as set out in
paragraph 2.1.11 of the Deed does not conflict with any law or regulation of the British Virgin Islands. 

  

	5.	This opinion is confined to the matters expressly opined on herein and given on the basis of the laws of the British Virgin Islands as they are in force and applied by the British
Virgin Islands courts at the date of this opinion. We have made no investigation of, and express no opinion on, the laws of any other jurisdiction. We express no opinion as to matters of fact. Except as specifically stated herein, we make no comment
with respect to any representations and warranties which may be made by or with respect to the Company in the Documents. We express no opinion with respect to the commercial terms of the transactions the subject of this opinion.


  

	6.	The opinions set out above are subject to the following qualifications: 

  

	 	(a)	The term “enforceable” as used above means that the obligations assumed by the Company under the relevant instrument are of a type which the courts of the British Virgin
Islands enforce. It does not mean that those obligations will necessarily be enforced in all circumstances in accordance with their terms. In particular: 

  

	 	(i)	rights and obligations may be limited by bankruptcy, insolvency, liquidation, arrangement and other similar laws of the British Virgin Islands of general application affecting the
rights of creditors; 

  

 4 









	 	(ii)	claims under the Documents may become barred under the laws relating to limitation of actions in the British Virgin Islands or may be or become subject to defences of set-off or
counterclaim; 

  

	 	(iii)	equitable remedies such as injunctions and orders for specific performance are discretionary and will not normally be available where damages are considered an adequate remedy and
equitable rights may be defeated by a bona fide purchaser for value without notice; 

  

	 	(iv)	where obligations are to be performed in a jurisdiction outside the British Virgin Islands they may not be enforceable under the laws of the British Virgin Islands to the extent
that such performance would be contrary to the laws of that jurisdiction or contrary to mandatory laws or public policy of that jurisdiction; 

  

	 	(v)	strict legal rights may be qualified by doctrines of good faith and fair dealing—for example a certificate or calculation as to any matter might be held by a British Virgin
Islands court not to be conclusive if it could be shown to have an unreasonable or arbitrary basis, or in the event of manifest error; 

  

	 	(vi)	enforcement may be prevented by reason of fraud, misrepresentation, public policy or mistake or limited by the doctrine of frustration of contracts; 

  

	 	(vii)	provisions, for example, for the payment of additional interest in certain circumstances, may be unenforceable to the extent a court of the British Virgin Islands determines such a
provision to be a penalty; and 

  

	 	(viii)	enforcement may be limited by the principle of forum non conveniens or analogous principles. 

  

	 	(b)	The courts in the British Virgin Islands will determine in their discretion whether or not an illegal or unenforceable provision may be severed. 

  

	 	(c)	The courts of the British Virgin Islands may refuse to give effect to a provision in respect of the cost of unsuccessful litigation brought before those courts or where the courts
themselves have made an order for costs. 

  

	 	(d)	In certain circumstances provisions in the Documents that (i) the election of a particular remedy does not preclude recourse to one or more others, or (ii) delay or
failure to exercise a right or remedy will not operate as a waiver of any such right or remedy, may not be enforceable. 

  

	 	(e)	We express no opinion in relation to provisions making reference to foreign statutes in the Documents. 

  

	7.	This opinion is rendered for the benefit of [—] [who are original parties to the Documents] and the benefit of their legal counsel (in that
capacity only) in connection with the transactions contemplated by the Documents only. [It may be disclosed to the successors and assigns of [—] only with our prior written consent.] It may not be disclosed to or
relied on by any other party or for any other purpose. 

 Yours faithfully 
 HARNEY WESTWOOD & RIEGELS
