Ladies and Gentlemen:
 
The agreement will set forth the terms and conditions pursuant to which Lihua
Wang (“Seller”) will sell to Cloverbay International Limited, a British Virgin

common stock of NF Energy Saving Corporation of America, a Delaware corporation
(“NFES”), as follows:
 
1.  Seller will sell to Purchaser, and Purchaser will purchase from Seller, the

2.  Seller represents that:
 
(a)  Seller owns the Shares free and clear of any liens or options, rights or
other security or other interests in the Shares;
 
(b)  Seller has the right to sell the Shares to Purchaser, and neither the
execution of this Agreement nor the sale of the Shares pursuant to this
Agreement violates any agreements to which Seller is a party or any law to which
Seller is subject.
 
3.  Seller makes no representation or warranty as to the business, financial
condition or prospects of NFES.
 
4.  Purchaser represents and warrants to Seller as follows:
 
(a)  Purchaser understands that the offer and sale of the Shares is being made
only by means of this Agreement, and no representations or warranties are being
made except as set forth in this Agreement.
 
(b)  Purchaser is not acquiring the Shares as a result of, and will not itself
engage in, any “directed selling efforts” (as defined in Regulation S of the
Securities and Exchange Commission) in the United States in respect of the
Shares which would include any activities undertaken for the purpose of, or that
could reasonably be expected to have the effect of, conditioning the market in
the United States for the resale of the Shares; provided, however, that
Purchaser may sell or otherwise dispose of the Shares in a manner permitted by
applicable law.
 
(c)  Purchaser acknowledges and agrees that none of the Shares have been
registered under the Securities Act, or under any state securities or “blue sky”
laws of any state of the United States, and, unless so registered, may not be
offered or sold in the United States or, directly or indirectly, to U.S.
Persons, as that term is defined in Regulation S, except in accordance with the
provisions of Regulation S, pursuant to an effective registration statement
under the Securities Act, or pursuant to an exemption from, or in a transaction
not subject to, the registration requirements of the Securities Act and in each
case in accordance with applicable state and provincial securities laws.
 

--------------------------------------------------------------------------------

(d)  Purchaser acknowledges and agrees that NFES will refuse to register any
transfer of the Shares not made in accordance with the provisions of Regulation
S, pursuant to an effective registration statement under the Securities Act or
pursuant to an available exemption from the registration requirements of the
Securities Act and in accordance with applicable state and provincial securities
laws.
 
(e)  Purchaser represents and warrants that no broker or finder was involved
directly or indirectly in connection with his or her purchase of the Shares
pursuant to this Agreement. Purchaser shall indemnify the Issuer and hold it
harmless from and against any manner of loss, liability, damage or expense,
including fees and expenses of counsel, resulting from a breach of Purchaser’s
warranty contained in this Paragraph 3(e).
 
(f)  Purchaser understands that it has no registration rights with respect to
the Shares.
 
(g)  Purchaser is not a citizen or resident of the United States.

either directly or indirectly any of the Shares in the United States or to U.S.
Persons.
 
(i)  Purchaser is acquiring the Shares as principal for Purchaser’s own account,
for investment purposes only, and not with a view to, or for, resale,
distribution or fractionalization thereof, in whole or in part, and no other
person has a direct or indirect beneficial interest in such Shares.
 
(j)  Purchaser is not an underwriter of, or dealer in, the common stock of NFES,
nor is Purchaser participating, pursuant to a contractual agreement or
otherwise, in the distribution of the Shares.
 
(k)  Purchaser is not aware of any advertisement of any of the Shares.
 
(l)  No person has made to Purchaser any written or oral representations:
 
(i)  that any person will resell or repurchase any of the Shares;
 
(ii)  that any person will refund the purchase price of any of the Shares;
 
(iii)  as to the future price or value of any of the Shares; or
 
(iv)  that any of the Shares will be listed and posted for trading on any stock
exchange or automated dealer quotation system or that application has been made
to list and post any of the Shares of NFES on any stock exchange or automated
dealer quotation system.
 
(m)  Purchaser has such knowledge and experience in financial and business
matters as to enable Purchaser to understand the nature and extent of the risks
involved in purchasing the Shares. Purchaser is fully aware that such
investments can and sometimes do result in the loss of the entire investment.
Purchaser has engaged his or her own counsel and accountants to the extent that
Purchaser deems it necessary.
