Exhibit 10.2
                                                              September 18, 2006

To the Board of Directors of
Zingerang, Inc. (the "Company"):

Gentlemen:

The undersigned (the  Subscriber")  hereby  subscribes to purchase FORTY MILLION
(40,000,000) shares of Zingerang, Inc.'s common stock (the "Founders Shares") at
a price of $0.00025 per share, representing a total purchase price of $ 10,000.

As  a  purchaser  of  Founders  Shares  offered  to  founders,   the  Subscriber
understands that, the Company intends to offer additional shares of common stock
in one or more private offerings (the "Private Offerings"). After the completion
of the Private Offerings, the Company has agreed to file with the Securities and
Exchange  Commission  ("SEC") an SB-2 registration  statement (the "Registration
Statement") to register  certain shares of common stock described in its Private
Offerings and to exercise its reasonable best efforts to cause the  Registration
Statement  to  become  effective.  The  Company  has also  agreed  to  request a
broker-dealer to file with the National Association of Securities Dealers,  Inc.
(the  "NASD") to secure the listing or quotation of its Common Stock on the Over
the Counter Bulletin Board market maintained by the NASD.

As an inducement to the  purchasers of the Private  Offerings and to NASD market
makers to establish a public market for the common stock, the undersigned hereby
agrees that from the date hereof and until two (2) years after the  Registration
Statement is declared  effective by the SEC (the "Lock-up Term"), the Subscriber
will not sell or offer to sell any  unregistered  shares of the Company's common
stock  which  the  Subscriber  owns as may be  permitted  pursuant  to Rule  144
promulgated under the Securities Act of 1933, as amended (the "Securities Act").

Any shares of common stock acquired by the undersigned in the Private  Offerings
and included in the  Registration  Statement  will not be subject to the lock-up
provisions of this Agreement.

Once the Lock-up Term has expired,  the Subscriber will be entitled to piggyback
registration  rights.  If the Company proposes to file a registration  statement
under the  Securities Act with respect to an offering for its own account of any
class of its equity securities (other than a registration  statement on Form S-8
(or any successor form) or any other  registration  statement relating solely to
employee  benefit  plans  or filed  in  connection  with an  exchange  offer,  a
transaction to which Rule 145 (or any successor  provision) under the Securities
Act  applies or an  offering  of  securities  solely to the  Company's  existing
shareholders),  then the Company shall in each case give written  notice of such
proposed  filing to the Subscriber as soon as practicable  (but no later than 20
business days) before the  anticipated  filing date, and such notice shall offer
the  Subscriber the  opportunity to register such number of Founders  Shares the
Subscriber may request.  The  Subscriber  shall so advise the Company in writing

                                       1


within 10  business  days  after the date on which  the  Company's  notice is so
given,  setting forth the number of Founders  Shares for which  registration  is
requested.  If the Company's  offering is to be an  underwritten  offering,  the
Company shall use its reasonable best efforts to cause the managing  underwriter
or  underwriters  to permit the  Subscriber to include the  requested  number of
Founders Shares in such offering on the same terms and conditions as any similar
securities of the Company included therein.  Once the registration  statement is
declared  effective by the SEC, the Subscriber  will not sell or distribute more
than 25% of  Subscriber's  Founders Shares  included in the  registration  every
ninety (90) days.

In  furtherance  of the  foregoing,  the  Company  and its  transfer  agent  and
registrar are hereby  authorized to decline to remove  restrictive  legends from
any share  certificates held by the undersigned if such removal would constitute
a violation or breach of this Agreement.

This agreement  shall be binding on the Subscriber  and the  successors,  heirs,
personal representatives and assigns of the Subscriber.
