(the &ldquo;Seller&rdquo;) entered into an investment agreement (the &ldquo;Investment Agreement&rdquo;) with YZ Healthcare L.P., an
exempted partnership established under the laws of the Cayman Islands (the &ldquo;Buyer&rdquo;) in connection with the potential sale
of the shares of the Issuer by the Seller. Pursuant to the Investment Agreement, the Buyer will pay a deposit in cash (the &ldquo;Deposit&rdquo;)
to the Seller within five business days after the date of the Investment Agreement.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">By entering into the Investment Agreement, the
Seller contemplates selling all the shares of the Issuer held by it, including its right to Exchange Shares, to the Buyer. In order to
complete the contemplated sales in an orderly manner, the Seller agrees to communicate, discuss and negotiate with other potential purchasers
during a three-month period beginning on the date of the payment of the Deposit (the &ldquo;Deposit Payment Date&rdquo;) based on the
terms and conditions proposed by the Buyer which provide, among other things, that any person who would purchase the shares of the Issuer
from the Seller will participate in such purchase through subscribing for a limited partnership interest in the Buyer. In addition, the
Buyer has a right to elect to purchase all of the shares of the Issuer that the Seller would sell to any person (other than any of its
affiliate or an existing limited partner) at the same price and subject to the same material terms and conditions proposed by such person
for a three-month period beginning on the Deposit Payment Date.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-indent: 0.5in">Under the Investment Agreement, the Buyer has
granted the Seller an option to sell to the Buyer a number of Common Shares of the Issuer (the &ldquo;Put Option&rdquo;). The number
of Common Shares under the Put Option (the &ldquo;Put Option Shares&rdquo;) would be calculated by dividing the amount of US$119,345,174
by the price for each Common Share (the &ldquo;Put Option Exercise Price&rdquo;) determined based on the agreed-upon valuation of the
Issuer and the total outstanding shares of the Issuer (without giving effect to the issuance of the Exchange Shares). If the Buyer and
the Seller enter into a share purchase agreement with respect to any shares of the Issuer prior to the end of the three-month period
beginning on the Deposit Payment Date, the Seller may exercise the Put Option prior to the closing of the sales under such share purchase
agreement to sell the Put Option Shares to the Buyer. If no such share purchase agreement is executed during the three-month period beginning
on the Deposit Payment Date, the Seller may exercise the Put Option within 15 business days immediately after the end of the three-month
period to sell the Put Option Shares to the Buyer.</P>

the Seller will grant the Buyer an option (the &ldquo;Call Option&rdquo;) to purchase a number of the Exchange Shares equal to the number
of the Put Option Shares sold to the Buyer pursuant to the Put Option. The purchase price for each Exchange Share under the Call Option
would be the amount equal to (i)&nbsp;the result of the agreed-upon valuation of the Issuer multiplied by two and divided by the total
outstanding shares of the Issuer (after giving effect to the issuance of the Exchange Shares), minus (ii)&nbsp;the Put Option Exercise
Price.</P>
