interest, whatsoever in any corporation, partnership, or other form of business
organization (any such organization is referred to as a “Subsidiary”).

(b)

4.21(b) sets forth true and complete copies of the charter of each Subsidiary,
as well as any limited liability company agreement, operating agreement or
shareholder agreement relating to such Subsidiary, and any acquisition agreement
relating to any Subsidiary.  All corporate or other action that has been taken
by any Subsidiary has been duly authorized and does not conflict with or violate
any provision of its charter, bylaws or other organizational documents.

(c)

Each Subsidiary (i) is duly organized and validly existing under the laws of its
jurisdiction of organization, (ii) has all requisite and necessary power and
authority to own, operate or lease those assets or properties which are owned,
operated or leased by it and to conduct its business as it has been and
currently is being conducted, (iii) is qualified to do business in all
jurisdictions where the failure to be so qualified would have a material adverse
effect on its business.

(d)

Except as set forth in Schedule 4.21(d), all outstanding shares of capital stock
or other ownership interests of each Subsidiary are validly issued, fully paid,
nonassessable and free of preemptive rights and are owned (either directly or
indirectly) by VSCO without any encumbrances.

4.23

Internal Accounting Controls.  VSCO maintains a system of internal accounting
controls sufficient to provide reasonable assurance that (i) transactions are
executed in accordance with management’s general or specific authorizations,
(ii) transactions are recorded as necessary to permit preparation of financial
statements in conformity with U.S. GAAP and to maintain asset accountability,

13

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

(iii) access to assets is permitted only in accordance with management’s general
or specific authorization, and (iv) the recorded accountability for assets is
compared with the existing assets at reasonable intervals and appropriate action
is taken with respect to any differences.  VSCO has established disclosure
controls and procedures (as defined in Exchange Act Rules 13a-15(e) and
15d-15(e)) for VSCO and designed such disclosure controls and procedures to
ensure that material information relating to VSCO is made known to the
certifying officers by others within those entities, particularly during the
period in which the VSCO’s Form 10-KSB or 10-QSB, as the case may be, is being
prepared.  VSCO’s certifying officers have evaluated the effectiveness of VSCO’s
controls and procedures as of the end of the filing period prior to the filing
date of the Form 10-QSB for the quarter ended September 30, 2007 (such date, the
“Evaluation Date”).  VSCO presented in its most recently filed Form 10-QSB the
conclusions of the certifying officers about the effectiveness of the disclosure
controls and procedures based on their evaluations as of the Evaluation Date.
 Since the Evaluation Date, there have been no significant changes in VSCO’s
internal controls (as such term is defined in Item 307(b) of Regulation S-K
under the Exchange Act) or, to VSCO’s knowledge, in other factors that could
significantly affect VSCO’s internal controls.

4.24

Intentionally Left Blank.  

4.25

Application of Takeover Protections.  VSCO and its board of directors have taken
all necessary action, if any, in order to render inapplicable any control share
acquisition, business combination, poison pill (including any distribution under
a rights agreement) or other similar anti-takeover provision under VSCO’s
certificate or articles of incorporation (or similar charter documents) or the
laws of its state of incorporation that is or could become applicable to Tianyin
or the Shareholders as a result of the Acquisition or the exercise of any rights
by Tianyin or the Shareholders pursuant to this Agreement.

4.26

No SEC or NASD Inquiries.  Neither VSCO nor any of its past or present officers
or directors is, or has ever been, the subject of any formal or informal inquiry
or investigation by the SEC or NASD.  

4.27

Restrictions on Business Activities.  Except as disclosed on Schedule 4.27
hereto, there is no agreement, commitment, judgment, injunction, order or decree
binding upon VSCO or to which VSCO is a party which has or could reasonably be
expected to have the effect of prohibiting or materially impairing any business
practice of VSCO, any acquisition of property by VSCO or the conduct of business
by Tianyin or VSCO as currently conducted, other than such effects, individually
or in the aggregate, which have not had and could not reasonably be expected to
have a Material Adverse Effect on VSCO.

4.28

Interested Party Transactions.

Except as set forth in the Schedule 4.28 hereto or as reflected in the financial
statements to be delivered hereunder, no employee, officer, director or
shareholder of VSCO or a member of his or her immediate family is indebted to
VSCO, nor are VSCO indebted (or committed to make loans or extend or guarantee
credit) to any of them, other than (i) for payment of salary for services
rendered, (ii) reimbursement for reasonable expenses incurred on behalf of VSCO,
and (iii) for other employee benefits made generally available to all employees.
 Except as set forth in Schedule 4.28, to the knowledge of VSCO, no employee,
officer, director or shareholder or any member of their immediate families is,
directly or indirectly, interested in any material contract with VSCO (other
than such contracts as relate to any such individual ownership of interests in
or securities of VSCO).    

4.29

Disclosure. The representations and warranties and statements of fact made by
VSCO in this Agreement are, as applicable, accurate, correct and complete and do
not contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements and information
contained herein not false or misleading.

14

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

4.30

Material Adverse Effect.  For the purposes of VSCO and its Subsidiary for this
Agreement, "Material Adverse Effect" means any adverse effect on the business,
operations, properties, prospects, or financial condition of either VSCO or its
Subsidiaries on any condition, circumstance, or situation that could result in
litigation, claims, disputes or property loss in excess of US $10,000 in the
future, or that would prohibit or otherwise materially interfere with the
ability of any party to this Agreement to perform any of its obligations under
this Agreement in any material respect.  

4.31

Due Diligence.  VSCO has had the opportunity to perform all due diligence
investigations of Tianyin and its business as VSCO as deemed necessary or
appropriate and to ask all questions of the officers and directors of Tianyin
that VSCO wished to ask, and VSCO has received satisfactory answers to all of
its questions regarding Tianyin.  VSCO has had access to all documents and
information about Tianyin and has reviewed sufficient information to allow it to
make the satisfactory evaluation on the merits and risks of the transactions
contemplated by this Agreement. Notwithstanding the foregoing, nothing herein
shall derogate from or otherwise modify the representations and warranties of
Tianyin set forth in this Agreement, on which VSCO has relied in making an
exchange of newly issued VSCO Shares for shares of Tianyin Common Stock held by
Tianyin Shareholders.

ARTICLE 5

INDEMNIFICATION

5.1

VSCO Indemnification.  For a period of one year after the Closing, the Shell
Indemnifying Shareholder agrees to indemnify Tianyin, the Shareholders and each
of the officers, agents and directors of Tianyin or the Shareholders against any
loss, liability, claim, damage or expense (including, but not limited to, any
and all expenses whatsoever reasonably incurred in investigating, preparing or
defending against any litigation, commenced or threatened, or any claim
whatsoever) (each an “Indemnified Party”) to which it or they may become subject
arising out of or based on either (i) any breach of or inaccuracy in any of the
representations and warranties or covenants or conditions made by VSCO and/or
the VSCO Shareholders in this Agreement; or (ii) any and all liabilities arising
out of or in connection with: (A) any of the assets of VSCO or any Subsidiary
prior to the Closing; or (B) the operations of VSCO prior to the Closing (the
“VSCO Shareholders Indemnification”), except to the extent that such breach or
liability does not result in a Material Adverse Effect (as defined in Section
4.30).  Notwithstanding anything provided for herein, the Indemnifying Party’s
total obligation under this Section 5.1 shall be limited to and shall not under
any circumstances exceed US $200,000.  

5.2

Indemnification Procedures.  If any action shall be brought against any
Indemnified Party in respect of which indemnity may be sought pursuant to this
Agreement, such Indemnified Party shall promptly notify the Indemnifying Party
in writing, and the Indemnifying Party shall have the right to assume the
defense thereof with counsel of its own choosing.  Any Indemnified Party shall
have the right to employ separate counsel in any such action and participate in
the defense thereof, but the fees and expenses of such counsel shall be at the
expense of such Indemnified Party except to the extent that the employment
thereof has been specifically authorized by the Indemnifying Party in writing,
the Indemnifying Party has failed after a reasonable period of time to assume
such defense and to employ counsel or in such action there is, in the reasonable
opinion of such separate counsel, a material conflict on any material issue
between the position of the Indemnifying Party and the position of such
Indemnified Party.  The Indemnifying Party will not be liable to any Indemnified
Party under this Article 5 for any settlement by an Indemnified Party effected
without the Indemnifying Party’s prior written consent, which shall not be
unreasonably withheld or delayed; or to the extent, but only to the extent that
a loss, claim, damage or liability is attributable to any Indemnified Party’s
indemnification pursuant to this Article 5.
