(collectively, the “Disclosure Package”), the Company represents and warrants to
the Purchasers, as of the date hereof, that:
 
2.1           Organization; Good Standing.  The Company is a corporation duly

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

 

2.2           Authority.  The Company has the full corporate power, authority
and legal right to execute and deliver this Agreement and to perform all of its
obligations and covenants hereunder.  Other than the filing with the SEC of the
prospectus supplement required by the Registration Statement pursuant to Rule
424(b) under the 1933 Act (the “Prospectus Supplement”) supplementing the base
prospectus forming part of the Registration Statement (the “Prospectus”) and any
other filings as may be required by any state securities agencies, no further
filing, consent or authorization is required by the Company, its board of
directors or its stockholders or other governing body.  The execution and
delivery of this Agreement by the Company, the performance by the Company of its
obligations and covenants hereunder and the consummation by the Company of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action.  This Agreement constitutes a valid and legally binding
obligation of the Company, enforceable against the Company in accordance with
its terms, except as the enforceability thereof may be limited by bankruptcy,
insolvency or other similar laws affecting the enforceability of creditors’
rights in general or by general principles of equity.
 
2.3           No Legal Bar; Conflicts.  Neither the execution and delivery of
this Agreement, nor the consummation of the transactions contemplated hereby,
violates any provision of the Certificate of Incorporation, as amended, or
By-Laws of the Company or any law, statute, ordinance, regulation, order,
judgment or decree of any court or governmental agency, or conflicts with or
results in any breach of any of the terms of or constitutes a default under or
results in the termination of or the creation of any lien pursuant to the terms
of any contract or agreement to which the Company is a party or by which the
Company or any of its assets is bound.
 
2.4           Non-Assessable Shares; Registration Statement.  The Securities
being issued hereunder have been duly authorized and, the Shares, when issued to
the Purchasers for the consideration herein provided, and the Warrant Shares
upon exercise of the Warrants, will be validly issued, fully paid and
non-assessable.  The issuance by the Company of the Securities has been
registered under the 1933 Act, the Securities are being issued pursuant to the
Registration Statement and all of the Securities are freely transferable and
freely tradable by each of the Purchasers without restriction. The Registration
Statement is effective and available for the issuance of the Securities
thereunder and the Company has not received any notice that the SEC has issued
or intends to issue a stop-order with respect to the Registration Statement or
that the SEC otherwise has suspended or withdrawn the effectiveness of the
Registration Statement, either temporarily or permanently, or intends or has
threatened in writing to do so. The “Plan of Distribution” section under the
Registration Statement permits the issuance and sale of the Securities
hereunder. Upon receipt of the Securities, each of the Purchasers will have good
and marketable title to the Securities. The Registration Statement and any
prospectus included therein, including the Prospectus and the Prospectus
Supplement, complied in all material respects with the requirements of the 1933
Act and the Securities Act of 1934, as amended (the “1934 Act”) and the rules
and regulations of the SEC promulgated thereunder and all other applicable laws
and regulations. At the time the Registration Statement and any amendments
thereto became effective, at the date of this Agreement and at each deemed
effective date thereof pursuant to Rule 430B(f)(2) of the 1933 Act, the
Registration Statement and any amendments thereto complied and will comply in
all material respects with the requirements of the 1933 Act and did not and will
not contain any untrue statement of a material fact or omit to state any
material fact required to be stated therein or necessary to make the statements
therein not misleading. The Prospectus and any amendments or supplements thereto
(including, without limitation the Prospectus Supplement), at the time the
Prospectus or any amendment or supplement thereto was issued and at the Closing
Date, complied, and will comply, in all material respects with the requirements
of the 1933 Act and did not, and will not, contain any untrue statement of a
material fact or omit to state a material fact necessary in order to make the
statements therein, in light of the circumstances under which they were made,
not misleading.  The Registration Statement is available under the 1933 Act to
be used by the Company for the offering and sale of the Securities contemplated
by this Agreement, and the SEC has not notified the Company of any objection to
the use of the form of the Registration Statement pursuant to Rule 401(g)(1)
under the 1933 Act. The filing of the Company’s Annual Report on Form 10-K/A for
the year ended June 30, 2011 qualifies under the 1933 Act as a Section 10(a)(3)
update to the Registration Statement. The Registration Statement meets the
requirements set forth in Rule 415(a)(1)(x) under the 1933 Act. At the earliest
time after the filing of the Registration Statement that the Company or another
offering participant made a bona fide offer (within the meaning of Rule
164(h)(2) under the 1933 Act) relating to any of the Securities, the Company was
not and is not an “Ineligible Issuer” (as defined in Rule 405 under the 1933
Act). The Company (i) has not distributed any offering material in connection
with the offer or sale of any of the Securities and (ii) until no Purchaser
holds any of the Securities, shall not distribute any offering material in
connection with the offer or sale of any of the Securities to, or by, any of the
Purchasers (if required), in each case, other than the Registration Statement,
the Prospectus or the Prospectus Supplement.

therein and financial statements and schedules thereto and documents
incorporated by reference therein being hereinafter referred to as the “SEC

respective representatives true, correct and complete copies of the SEC
Documents not available on the EDGAR system.  As of their respective dates, the
SEC Documents complied in all material respects with the requirements of the
1934 Act and the rules and regulations of the SEC promulgated thereunder
applicable to the SEC Documents, and none of the SEC Documents, at the time they
were filed with the SEC, contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary in
order to make the statements therein, in the light of the circumstances under
which they were made, not misleading.  As of their respective dates, the
financial statements of the Company included in the SEC Documents complied as to
form in all material respects with applicable accounting requirements and the
published rules and regulations of the SEC with respect thereto.  Such financial
statements have been prepared in accordance with generally accepted accounting
principles, consistently applied, during the periods involved (except (i) as may
be otherwise indicated in such financial statements or the notes thereto, or
(ii) in the case of unaudited interim statements, to the extent they may exclude
footnotes or may be condensed or summary statements) and fairly present in all
material respects the financial position of the Company as of the dates thereof
and the results of its operations and cash flows for the periods then ended
(subject, in the case of unaudited statements, to normal year-end audit
adjustments).  No other information provided by or on behalf of the Company to
the Purchasers which is not included in the SEC Documents, including, without
limitation, information provided to any Purchasers by the Company in
anticipation of this transaction, contains any untrue statement of a material
fact or omits to state any material fact necessary in order to make the
statements therein, in the light of the circumstance under which they are or
were made, not misleading.

Securities shall be required to provide the Company with any notice thereof or
otherwise make any delivery to the Company pursuant to this Agreement. The

Company shall not, and the Company shall cause each of its officers, directors,
employees and agents, not to, provide any Purchaser with any material,
non-public information regarding the Company from and after the issuance of the

contained in this Section 4.8 by the Company or any of its officers, directors,
employees and agents (as determined in the reasonable good faith judgment of
such Purchaser), in addition to any other remedy provided herein, such Purchaser
shall have the right to make a public disclosure, in the form of a press
release, public advertisement or otherwise, of such material, non-public
information without the prior approval by the Company or any of its officers,
directors, employees or agents. No Purchaser shall have any liability to the
Company or any of its officers, directors, employees, stockholders or agents,
for any such disclosure. Subject to the foregoing, neither the Company nor any
Purchaser shall issue any press releases or any other public statements with
respect to the transactions contemplated hereby; provided, however, the Company
shall be entitled, without the prior approval of any Purchaser, to make any
press release or other public disclosure with respect to such transactions (i)
in substantial conformity with the 8-K Filing and contemporaneously therewith
and (ii) as is required by applicable law and regulations (provided that in the
case of clause (i) each Purchaser shall be consulted by the Company in
connection with any such press release or other public disclosure prior to its
release). Without the prior written consent of the applicable Purchaser, other
then with respect to the attachment of this Agreeemnt to the 8-K Filing, the

Warrants set forth therein), less the number of Warrant Shares represented by
any such Warrants that have been exercised.
 
4.10         Conduct of Business.  The business of the Company shall not be
conducted in violation of any law, ordinance or regulation of any governmental
entity, except where such violations would not result, either individually or in
the aggregate, in a material adverse effect.

ARTICLE 5
 
REGISTER; TRANSFER AGENT INSTRUCTIONSL LEGEND
 
5.1           Register. The Company shall maintain at its principal executive
offices (or such other office or agency of the Company as it may designate by
notice to each holder of Securities), a register for the Shares and the Warrants
in which the Company shall record the name and address of the person in whose
name the Shares and the Warrants have been issued (including the name and
address of each transferee), the number of Shares held by such person and the
number of Warrant Shares issuable upon exercise of the Warrants held by such
person. The Company shall keep the register open and available at all times
during business hours for inspection of any Purchaser or its legal
representatives.
 
5.2           Transfer Agent Instructions. The Company shall issue irrevocable
instructions to the Transfer Agent in the form previously provided to the
Company (the “Irrevocable Transfer Agent Instructions”) to issue certificates or
credit shares to the applicable balance accounts at DTC, registered in the name
of each Purchaser or its respective nominee(s), for the Shares and the Warrant
Shares in such amounts as specified from time to time by each Purchaser to the
Company upon delivery of the Shares or the exercise of the Warrants (as the case
may be). The Company represents and warrants that no instruction other than the
Irrevocable Transfer Agent Instructions referred to in this Section 5.2 will be
given by the Company to the Transfer Agent with respect to the Securities, and
that the Securities shall otherwise be freely transferable on the books and
records of the Company. If a Purchaser effects a sale, assignment or transfer of
the Securities, the Company shall permit the transfer and shall promptly
instruct the Transfer Agent to issue one or more certificates or credit shares
to the applicable balance accounts at DTC in such name and in such denominations
as specified by such Purchaser to effect such sale, transfer or assignment. The
Company acknowledges that a breach by it of its obligations hereunder will cause
irreparable harm to each Purchaser. Accordingly, the Company acknowledges that
the remedy at law for a breach of its obligations under this Section 5.2 will be
inadequate and agrees, in the event of a breach or threatened breach by the
Company of the provisions of this Section 5.2, that each Purchaser shall be
entitled, in addition to all other available remedies, to an order and/or
injunction restraining any breach and requiring immediate issuance and transfer,
without the necessity of showing economic loss and without any bond or other
security being required.
