    (b)           Organization and
Qualification.  The Company and each of the Subsidiaries is an
entity duly incorporated or otherwise organized, validly existing and in good
standing under the laws of the jurisdiction of its incorporation or

properties and assets and to carry on its business as currently
conducted.  Neither the Company nor any Subsidiary is in violation nor
default of any of the provisions of its respective certificate or articles of
incorporation, bylaws or other organizational or charter
documents.  Each of the Company and the Subsidiaries is duly qualified
to conduct business and is in good standing as a foreign corporation or other
entity in each jurisdiction in which the nature of the business conducted or
property owned by it makes such qualification necessary, except where the
failure to be so qualified or in good standing, as the case may be, could not
have or reasonably be expected to result in: (i) a material adverse effect on
the legality, validity or enforceability of any Transaction Document, (ii) a
material adverse effect on the results of operations, assets, business,
prospects or condition (financial or otherwise) of the Company and the
Subsidiaries, taken as a whole, or (iii) a material adverse effect on the
Company’s ability to perform in any material respect on a timely basis its
obligations under any Transaction Document (any of (i), (ii) or (iii), a “Material Adverse
Effect”) and no Proceeding has been instituted in any such jurisdiction
revoking, limiting or curtailing or seeking to revoke, limit or curtail such
power and authority or qualification.

     

    (c)           Authorization;
Enforcement.  The Company has the requisite corporate power and
authority to enter into and to consummate the transactions contemplated by each
of the Transaction Documents and otherwise to carry out its obligations
hereunder and thereunder.  The execution and delivery of each of the
Transaction Documents by the Company and the consummation by it of the
transactions contemplated hereby and thereby have been duly authorized by all
necessary action on the part of the Company and no further action is required by
the Company, the Board of Directors or the Company’s stockholders in connection
therewith other than in connection with the Required Approvals.  Each
Transaction Document to which it is a party has been (or upon delivery will have
been) duly executed by the Company and, when delivered in accordance with the
terms hereof and thereof, will constitute the valid and binding obligation of
the Company enforceable against the Company in accordance with its terms, except
(i) as limited by general equitable principles and applicable bankruptcy,
insolvency, reorganization, moratorium and other laws of general application
affecting enforcement of creditors’ rights generally, (ii) as limited by laws
relating to the availability of specific performance, injunctive relief or other
equitable remedies and (iii) insofar as indemnification and contribution
provisions may be limited by applicable law.

     

    (d)           No
Conflicts.  The execution, delivery and performance by the
Company of the Transaction Documents, the issuance and sale of the Securities
and the consummation by it of the transactions contemplated hereby and thereby
to which it is a party do not and will not (i) conflict with or violate any
provision of the Company’s or any Subsidiary’s certificate or articles of
incorporation, bylaws or other organizational or charter documents, or (ii)
conflict with, or constitute a default (or an event that with notice or lapse of
time or both would become a default) under, result in the creation of any Lien
upon any of the properties or assets of the Company or any Subsidiary, or give
to others any rights of termination, amendment, acceleration or cancellation
(with or without notice, lapse of time or both) of, any agreement, credit
facility, debt or other instrument (evidencing a Company or Subsidiary debt or
otherwise) or other understanding to which the Company or any Subsidiary is a
party or by which any property or asset of the Company or any Subsidiary is
bound or affected, or (iii) subject to the Required Approvals, conflict with or
result in a violation of any law, rule, regulation, order, judgment, injunction,
decree or other restriction of any court or governmental authority to which the
Company or a Subsidiary is subject (including federal and state securities laws
and regulations), or by which any property or asset of the Company or a
Subsidiary is bound or affected; except in the case of each of clauses (ii) and
(iii), such as could not have or reasonably be expected to result in a Material

issued and paid for in accordance with the applicable Transaction Documents,
will be duly and validly issued, fully paid and non-assessable, free and clear
of all Liens imposed by the Company.  The Warrant Shares, when issued
in accordance with the terms of the Warrants, will be validly issued, fully paid
and nonassessable, free and clear of all Liens imposed by the
Company.  The Company has reserved from its duly authorized capital
stock the maximum number of shares of Common Stock issuable pursuant to this
Agreement and the Warrants. The issuance by the Company to the Purchasers of the
Securities has been registered under the Securities Act and all of the
Securities, when delivered, will be freely transferable and tradable on the
Trading Market by the Purchasers without restriction (other than any
restrictions arising solely from an act or omission of a Purchaser). The Company
has prepared and filed the Registration Statement, which became effective
on February 23, 2007 (the “Effective Date”), in
conformity with the requirements of the Securities Act including the Prospectus,
and such amendments and supplements thereto as may have been required to the

Statement or suspending or preventing the use of the Prospectus has been issued

Statement and any amendments thereto conformed and will conform in all material
respects to the requirements of the Securities 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; and the Prospectus and any amendments or supplements thereto, at
time the Prospectus or any amendment or supplement thereto was issued and at the

requirements of the Securities Act and did not and will not contain an untrue

to make the statements therein, in light of the circumstances under which they
were made, not misleading. The “Plan of Distribution” section under the

3.1(g).  No Person has any right of first refusal, preemptive
right, right of participation, or any similar right to participate in the
transactions contemplated by the Transaction Documents.  The issuance
and sale of the Securities will not obligate the Company to issue shares of
Common Stock or other securities to any Person (other than the Purchasers) and

agreements or other similar agreements with respect to the Company’s capital
stock to which the Company is a party or, to the knowledge of the Company,
between or among any of the Company’s stockholders.

forms, statements and other documents required to be filed by the Company under
the Securities Act and the Exchange Act, including pursuant to Section 13(a) or

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. The Company has never been an issuer subject to or identified in
Rule 144(i) under the Securities Act. The financial statements of the Company
included in the SEC Reports comply in all material respects with applicable
accounting requirements and the rules and regulations of the Commission with
respect thereto as in effect at the time of filing.  Such financial
statements have been prepared in accordance with United States generally
accepted accounting principles applied on a consistent basis during the periods
involved (“GAAP”), except as may
be otherwise specified in such financial statements or the notes thereto and
except that unaudited financial statements may not contain all footnotes
required by GAAP, and fairly present in all material respects the financial
position of the Company and its consolidated Subsidiaries as of and for the
dates thereof and the results of operations and cash flows for the periods then

adversely affects or challenges the legality, validity or enforceability of any
of the Transaction Documents or the Securities or (ii) could, if there were an
unfavorable decision, have or reasonably be expected to result in a Material
Adverse Effect.  Neither the Company nor any Subsidiary, nor any
director or officer thereof, is or has been the subject of any Action involving

claim of breach of fiduciary duty.  There has not been, and to the
knowledge of the Company, there is not pending or contemplated, any

    (k)      
     Labor
Relations.  No material labor dispute exists or, to the
knowledge of the Company, is imminent with respect to any of the employees of
the Company, which could reasonably be expected to result in a Material Adverse
Effect.  None of the Company’s or its Subsidiaries’ employees is a
member of a union that relates to such employee’s relationship with the Company
or such Subsidiary, and neither the Company nor any of its Subsidiaries is a
party to a collective bargaining agreement, and the Company and its Subsidiaries
believe that their relationships with their employees are good.  No
executive officer, to the knowledge of the Company, is, or is now expected to
be, in violation of any material term of any employment contract,
confidentiality, disclosure or proprietary information agreement or
non-competition agreement, or any other contract or agreement or any restrictive
covenant in favor of any third party, and the continued employment of each such
executive officer does not subject the Company or any of its Subsidiaries to any
liability with respect to any of the foregoing matters.  The Company
and its Subsidiaries are in compliance with all U.S. federal, state, local and
foreign laws and regulations relating to employment and employment practices,
terms and conditions of employment and wages and hours, except where the failure
to be in compliance could not, individually or in the aggregate, reasonably be
expected to have a Material Adverse Effect.

     

    (l)           
 Compliance.  Neither
the Company nor any Subsidiary: (i) is in default under or in violation of (and
no event has occurred that has not been waived that, with notice or lapse of
time or both, would result in a default by the Company or any Subsidiary under),
nor has the Company or any Subsidiary received notice of a claim that it is in
default under or that it is in violation of, any indenture, loan or credit
agreement or any other agreement or instrument to which it is a party or by
which it or any of its properties is bound (whether or not such default or
violation has been waived), (ii) is in violation of any judgment, decree or
order of any court, arbitrator or governmental body or (iii) is or has been in
violation of any statute, rule, ordinance or regulation of any governmental
authority, including without limitation all foreign, federal, state and local
laws applicable to its business and all such laws that affect the environment,
except in each case as could not have or reasonably be expected to result in a
Material Adverse Effect.

     

    (m)           Regulatory
Permits.  The Company and the Subsidiaries possess all
certificates, authorizations and permits issued by the appropriate federal,
state, local or foreign regulatory authorities necessary to conduct their
respective businesses as described in the SEC Reports, except where the failure
to possess such permits could not reasonably be expected to result in a Material
Adverse Effect (“Material Permits”),
and neither the Company nor any Subsidiary has received any notice of
proceedings relating to the revocation or modification of any Material
Permit.

     

    (n)           Title to
Assets.  The Company and the Subsidiaries have good and
marketable title in fee simple to all real property owned by them and good and
marketable title in all personal property owned by them that is material to the
business of the Company and the Subsidiaries, in each case free and clear of all
Liens, except for Liens as do not materially affect the value of such property
and do not materially interfere with the use made and proposed to be made of
such property by the Company and the Subsidiaries and Liens for the payment of
federal, state or other taxes, the payment of which is neither delinquent nor
subject to penalties.  Any real property and facilities held under
lease by the Company and the Subsidiaries are held by them under valid,
subsisting and enforceable leases with which the Company and the Subsidiaries
are in compliance.

    (o)           Patents and
Trademarks.  The Company and the Subsidiaries have, or have
rights to use, all patents, patent applications, trademarks, trademark
applications, service marks, trade names, trade secrets, inventions, copyrights,
licenses and other intellectual property rights and similar rights necessary or
material for use in connection with their respective businesses as described in
the SEC Reports and which the failure to so have could have a Material Adverse
Effect (collectively, the “Intellectual Property
Rights”).  Except as described in the SEC Reports, neither the
Company nor any Subsidiary has received a notice (written or otherwise) that any
of the Intellectual Property Rights used by the Company or any Subsidiary
violates or infringes upon the rights of any Person.  To the knowledge
of the Company, all such Intellectual Property Rights are enforceable and there
is no existing infringement by another Person of any of the Intellectual
Property Rights.  The Company and its Subsidiaries have taken
reasonable security measures to protect the secrecy, confidentiality and value
of all of their intellectual properties, except where failure to do so could
not, individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect.

     

    (p)           Insurance.  The
Company and the Subsidiaries are insured by insurers of recognized financial
responsibility against such losses and risks and in such amounts as are prudent
and customary in the businesses in which the Company and the Subsidiaries are
engaged, including, but not limited to, directors and officers insurance
coverage at least equal to the aggregate Subscription Amount.  Neither
the Company nor any Subsidiary has any reason to believe that it will not be
able to renew its existing insurance coverage as and when such coverage expires
or to obtain similar coverage from similar insurers as may be necessary to
continue its business without a significant increase in cost.

     

    (q)           Transactions With Affiliates
and Employees.  Except as disclosed in the SEC Reports, none of
the officers or directors of the Company and, to the knowledge of the Company,
none of the employees of the Company is presently a party to any transaction
with the Company or any Subsidiary (other than for services as employees,
officers and directors), including any contract, agreement or other arrangement
providing for the furnishing of services to or by, providing for rental of real
or personal property to or from, or otherwise requiring payments to or from any
officer, director or such employee or, to the knowledge of the Company, any
entity in which any officer, director, or any such employee has a substantial
interest or is an officer, director, trustee or partner, in each case in excess
of $120,000 other than for (i) payment of salary or consulting fees for services
rendered, (ii) reimbursement for expenses incurred on behalf of the Company and
(iii) other employee benefits, including stock option agreements under any stock
option plan of the Company.

    (r)           Sarbanes-Oxley; Internal
Accounting Controls.  The Company is in material compliance
with all provisions of the Sarbanes-Oxley Act of 2002 which are applicable to it
as of the Closing Date.  The Company and the Subsidiaries maintain 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 GAAP and to
maintain asset accountability, (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. The Company has established disclosure controls and procedures (as
defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Company and
designed such disclosure controls and procedures to ensure that information
required to be disclosed by the Company in the reports it files or submits under
the Exchange Act is recorded, processed, summarized and reported, within the
time periods specified in the Commission’s rules and forms.  The
Company’s certifying officers have evaluated the effectiveness of the Company’s
disclosure controls and procedures as of the end of the period covered by the
Company’s most recently filed periodic report under the Exchange Act (such date,
the “Evaluation
Date”).  The Company presented in its most recently filed
periodic report under the Exchange Act 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 changes in the Company’s internal control over
financial reporting (as such term is defined in the Exchange Act) that has
materially affected, or is reasonably likely to materially affect, the Company’s
internal control over financial reporting.

     

    (s)           Certain
Fees.  The Purchasers shall have no obligation with respect to
any brokerage for finder’s fees or commissions or with respect to any claims
made by or on behalf of other Persons for any such fees or commissions that may
be due and payable by the Company in connection with the transactions
contemplated by the Transaction Documents.

     

    (t)           Investment Company.
The Company is not, and is not an Affiliate of, and immediately after receipt of
payment for the Securities, will not be or be an Affiliate of, an “investment
company” within the meaning of the Investment Company Act of 1940, as
amended.  The Company shall conduct its business in a manner so that
it will not become an “investment company” subject to registration under the
Investment Company Act of 1940, as amended.

     

    (u)           Registration
Rights.  Except for the right of the holders of certain
warrants issued by the Company on March 31, 2008 to require the Company to
effect the registration under the Securities Act of shares of Common Stock
underlying those warrants, no Person has any right to cause the Company to
effect the registration under the Securities Act of any securities of the
Company.

    (v)           Listing and Maintenance
Requirements.  The Common Stock is registered pursuant to
Section 12(b) or 12(g) of the Exchange Act, and the Company has taken no action
designed to, or which to its knowledge is likely to have the effect of,
terminating the registration of the Common Stock under the Exchange Act nor has
the Company received any notification that the Commission is contemplating
terminating such registration.  Except as disclosed in the SEC
Reports, the Company has not, in the 12 months preceding the date hereof,
received notice from any Trading Market on which the Common Stock is or has been
listed or quoted to the effect that the Company is not in compliance with the
listing or maintenance requirements of such Trading Market. Except as disclosed
in the SEC Reports, the Company is, immediately after the consummation of the
transactions contemplated by the Transaction Documents will be, and has no
reason to believe that it will not in the foreseeable future continue to be, in
compliance with all such listing and maintenance requirements.

     

    (w)           Application of Takeover
Protections.  The Company and the 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 the Company’s
certificate of incorporation (or similar charter documents) or the laws of its
state of incorporation that is or could become applicable to the Purchasers as a
result of the Purchasers and the Company fulfilling their obligations or
exercising their rights under the Transaction Documents, including without
limitation as a result of the Company’s issuance of the Securities and the
Purchasers’ ownership of the Securities.

     

    (x)           Disclosure.  Except
with respect to the material terms and conditions of the transactions
contemplated by the Transaction Documents, the Company confirms that neither it
nor any other Person acting on its behalf has provided any of the Purchasers or
their agents or counsel with any information that it believes constitutes or
might constitute material, non-public information which is not otherwise
disclosed in the Prospectus. The Company understands and confirms that the
Purchasers will rely on the foregoing representation in effecting transactions
in securities of the Company.  All of the disclosure furnished by or
on behalf of the Company to the Purchasers regarding the Company, its business
and the transactions contemplated hereby, including the Disclosure Schedules to
this Agreement, is true and correct and does not contain any untrue statement of
a material fact or omit to state any material fact necessary in order to make
the statements made therein, in light of the circumstances under which they were
made, not misleading. The press releases disseminated by the Company during the
twelve months preceding the date of this Agreement taken as a whole do not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary in order to make the statements
therein, in light of the circumstances under which they were made and when made,
not misleading.  The Company acknowledges and agrees that no Purchaser
makes or has made any representations or warranties with respect to the
transactions contemplated hereby other than those specifically set forth in
Section 3.2 hereof.

     

    (y)           No Integrated
Offering. Assuming the accuracy of the Purchasers’ representations and
warranties set forth in Section 3.2, neither the Company, nor any of its
Affiliates, nor any Person acting on its or their behalf has, directly or
indirectly, made any offers or sales of any security or solicited any offers to
buy any security, under circumstances that would cause this offering of the
Securities to be integrated with prior offerings by the Company for purposes of
any applicable shareholder approval provisions of any Trading Market on which
any of the securities of the Company are listed or
designated.   The issuance and sale of the Securities hereunder
does not contravene the rules and regulations of any Trading
Market.

    (z)           Solvency.  The
Company does not intend to incur debts beyond its ability to pay such debts as
they mature (taking into account the timing and amounts of cash to be payable on
or in respect of its debt).  The Company has no knowledge of any facts
or circumstances which lead it to believe that it will file for reorganization
or liquidation under the bankruptcy or reorganization laws of any jurisdiction
within one year from the Closing Date.  Schedule 3.1(z) sets
forth as of the date hereof all outstanding secured and unsecured Indebtedness
of the Company or any Subsidiary, or for which the Company or any Subsidiary has
commitments.  For the purposes of this Agreement, “Indebtedness” means
(x) any liabilities for borrowed money or amounts owed in excess of $50,000
(other than trade accounts payable incurred in the ordinary course of business),
(y) all guaranties, endorsements and other contingent obligations in respect of
indebtedness of others, whether or not the same are or should be reflected in
the Company’s balance sheet (or the notes thereto), except guaranties by
endorsement of negotiable instruments for deposit or collection or similar
transactions in the ordinary course of business; and (z) the present value of
any lease payments in excess of $50,000 due under leases required to be
capitalized in accordance with GAAP.  Neither the Company nor any
Subsidiary is in material default with respect to any Indebtedness.

     

    (aa)           Tax
Status.  Except for matters that would not, individually or in
the aggregate, have or reasonably be expected to result in a Material Adverse
Effect, the Company and each Subsidiary has filed all necessary federal, state
and foreign income and franchise tax returns and has paid or accrued all taxes
shown as due thereon, and the Company has no knowledge of a tax deficiency which
has been asserted or threatened against the Company or any
Subsidiary.

     

    (bb)           Foreign Corrupt
Practices.  Neither the Company, nor to the knowledge of the
Company, any agent or other person acting on behalf of the Company, has (i)
directly or indirectly, used any funds for unlawful contributions, gifts,
entertainment or other unlawful expenses related to foreign or domestic
political activity, (ii) made any unlawful payment to foreign or domestic
government officials or employees or to any foreign or domestic political
parties or campaigns from corporate funds, (iii) failed to disclose fully any
contribution made by the Company (or made by any person acting on its behalf of
which the Company is aware) which is in violation of law, or (iv) violated in
any material respect any provision of the Foreign Corrupt Practices Act of 1977,
as amended.

     

    (cc)           Accountants.  The
Company’s accounting firm is MSCM LLP, 8th Floor, 701 Evans Avenue, Toronto,
Ontario, Canada M9C 1A3.  To the knowledge and belief of the Company,
such accounting firm (i) is a registered public accounting firm as required by
the Exchange Act and (ii) shall express its opinion with respect to the
financial statements to be included in the Company’s Annual Report for the year
ending July 31, 2009.

    (dd)           
Acknowledgment
Regarding Purchasers’ Purchase of Securities.  The Company
acknowledges and agrees that each of the Purchasers is acting solely in the
capacity of an arm’s length purchaser with respect to the Transaction Documents
and the transactions contemplated thereby. The Company further acknowledges that
no Purchaser is acting as a financial advisor or fiduciary of the Company (or in
any similar capacity) with respect to the Transaction Documents and the
transactions contemplated thereby and any advice given by any Purchaser or any
of their respective representatives or agents in connection with the Transaction
Documents and the transactions contemplated thereby is merely incidental to the
Purchasers’ purchase of the Securities.  The Company further
represents to each Purchaser that the Company’s decision to enter into this
Agreement and the other Transaction Documents has been based solely on the
independent evaluation of the transactions contemplated hereby by the Company
and its representatives.

     

    (ee)           Acknowledgement Regarding
Purchaser’s Trading Activity.  Anything in this Agreement or
elsewhere herein to the contrary notwithstanding (except for Section 3.2(e)
hereof), it is understood and acknowledged by the Company that: (i) none of the
Purchasers have been asked by the Company to agree, nor has any Purchaser
agreed, to desist from purchasing or selling, long and/or short, securities of
the Company, or “derivative” securities based on securities issued by the
Company or to hold the Securities for any specified term; (ii) past or future
open market or other transactions by any Purchaser, specifically including,
without limitation, Short Sales or “derivative” transactions, before or after
the closing of this or future private placement transactions, may negatively
impact the market price of the Company’s publicly-traded securities; (iii) any
Purchaser, and counter-parties in “derivative” transactions to which any such
Purchaser is a party, directly or indirectly, presently may have a “short”
position in the Common Stock, and (iv) each Purchaser shall not be deemed to
have any affiliation with or control over any arm’s length counter-party in any
“derivative” transaction. The Company further understands and acknowledges that
(y) one or more Purchasers may engage in hedging activities at various times
during the period that the Securities are outstanding, including, without
limitation, during the periods that the value of the Warrant Shares deliverable
with respect to Securities are being determined, and (z) such hedging activities
(if any) could reduce the value of the existing stockholders’ equity interests
in the Company at and after the time that the hedging activities are being
conducted. The Company acknowledges that such aforementioned hedging activities
do not constitute a breach of any of the Transaction Documents.

     

    (ff)           Regulation M
Compliance.  The Company has not, and to its knowledge no one acting
on its behalf has, (i) taken, directly or indirectly, any action designed to
cause or to result in the stabilization or manipulation of the price of any
security of the Company to facilitate the sale or resale of any of the
Securities, (ii) sold, bid for, purchased, or, paid any compensation for
soliciting purchases of, any of the Securities, or (iii) paid or agreed to pay
to any Person any compensation for soliciting another to purchase any other
securities of the Company, other than, in the case of clauses (ii) and (iii),
compensation paid to the Company’s placement agent in connection with the
placement of the Securities.

    (gg)           FDA.  To
the Company’s knowledge, it is not in violation of the Federal Food, Drug and
Cosmetic Act, as amended, and the rules and regulations thereunder, except where
the violation thereof would not have a Material Adverse Effect.  There
is no pending, completed or, to the Company's knowledge, threatened, action
(including any lawsuit, arbitration, or legal or administrative or regulatory
proceeding, charge, complaint, or investigation) against the Company or any of
its Subsidiaries, and none of the Company or any of its Subsidiaries has
received any notice, warning letter or other communication from the U.S. Food
and Drug Administration (“FDA”) or any other
governmental entity, which (i) contests the premarket clearance, licensure,
registration, or approval of, the uses of, the distribution of, the
manufacturing or packaging of, the testing of, the sale of, or the labeling and
promotion of any Pharmaceutical Product, (ii) withdraws its approval of,
requests the recall, suspension, or seizure of, or withdraws or orders the
withdrawal of advertising or sales promotional materials relating to, any
Pharmaceutical Product, (iii) imposes a clinical hold on any clinical
investigation by the Company or any of its Subsidiaries, (iv) enjoins production
at any facility of the Company or any of its Subsidiaries, (v) enters or
proposes to enter into a consent decree of permanent injunction with the Company
or any of its Subsidiaries, or (vi) otherwise alleges any violation of any laws,
rules or regulations by the Company or any of its Subsidiaries, and which,
either individually or in the aggregate, would have a Material Adverse
Effect.  The Company has not been informed by the FDA that the FDA
will prohibit the marketing, sale, license or use in the United States of any
product proposed to be developed, produced or marketed by the Company nor has
the FDA expressed to the Company or any of its Subsidiaries any concern as to
approving or clearing for marketing any product being developed or proposed to
be developed by the Company.

     

    3.2     Representations and
Warranties of the Purchasers.  Each Purchaser, for itself and
for no other Purchaser, hereby represents and warrants as of the execution of
this Agreement on the date of this Agreement first written above to the Company
as follows (unless as of a specific date therein):

     

    (a)           Organization;
Authority.  Such Purchaser is either an individual or an entity
duly organized, validly existing and in good standing under the laws of the
jurisdiction of its organization with full right, corporate or partnership power
and authority to enter into and to consummate the transactions contemplated by
this Agreement and otherwise to carry out its obligations hereunder and
thereunder. The execution and delivery of this Agreement and performance by such
Purchaser of the transactions contemplated by this Agreement have been duly
authorized by all necessary corporate, partnership, limited liability company or
similar action, as applicable, on the part of such Purchaser.  Each
Transaction Document to which it is a party has been duly executed by such
Purchaser, and when delivered by such Purchaser in accordance with the terms
hereof, will constitute the valid and legally binding obligation of such
Purchaser, enforceable against it in accordance with its terms, except: (i) as
limited by general equitable principles and applicable bankruptcy, insolvency,
reorganization, moratorium and other laws of general application affecting
enforcement of creditors’ rights generally, (ii) as limited by laws relating to
the availability of specific performance, injunctive relief or other equitable
remedies and (iii) insofar as indemnification and contribution provisions may be
limited by applicable law.


    
      
         


      

      
        16

        
          

        

      

      
         


      

    


    (b)           Purchaser
Status.  At the time such Purchaser was offered the Securities,
it was, and as of the date hereof it is, and on each date on which it exercises
any Warrants for cash, it will be, either: (i) an “accredited investor” as
defined in Rule 501(a)(1), (a)(2), (a)(3), (a)(7) or (a)(8) under the Securities
Act or (ii) a “qualified institutional buyer” as defined in Rule 144A(a) under
the Securities Act.  Such Purchaser is not required to be registered
as a broker-dealer under Section 15 of the Exchange Act.

     

    (c)           Experience of Such
Purchaser.  Such Purchaser, either alone or together with its
representatives, has such knowledge, sophistication and experience in business
and financial matters so as to be capable of evaluating the merits and risks of
the prospective investment in the Securities, and has so evaluated the merits
and risks of such investment.  Such Purchaser is able to bear the
economic risk of an investment in the Securities and, at the present time, is
able to afford a complete loss of such investment.

     

    (d)           Certain Transactions and
Confidentiality. Such Purchaser has not, nor has any Person acting on
behalf of or pursuant to any understanding with such Purchaser, directly or
indirectly executed any purchases (other than from the Company pursuant any
exercises of warrants) or sales, including Short Sales, of the securities
of the Company during the period commencing as of the time that such Purchaser
first received a term sheet (written or oral) from the Company or any other
Person representing the Company setting forth the material terms of the
transactions contemplated hereunder. Notwithstanding the foregoing, in the case
of a Purchaser that is a multi-managed investment vehicle whereby separate
portfolio managers manage separate portions of such Purchaser’s assets and the
portfolio managers have no direct knowledge of the investment decisions made by
the portfolio managers managing other portions of such Purchaser’s assets, the
representation set forth above shall only apply with respect to the portion of
assets managed by the portfolio manager that made the investment decision to
purchase the Securities covered by this Agreement. Other than to other Persons
party to this Agreement and its representatives, such Purchaser has maintained
the confidentiality of all disclosures made to it in connection with this
transaction (including the existence and terms of this
transaction). Notwithstanding the foregoing, for avoidance of doubt,
nothing contained herein shall constitute a representation or warranty, or
preclude any actions, with respect to the identification of the availability of,
or securing of, available shares to borrow in order to effect Short Sales or
similar transactions in the future.

     

    The
Company acknowledges and agrees that the representations contained in Section
3.2 shall not modify, amend or affect such Purchaser’s right to rely on the
Company’s representations and warranties contained in this Agreement or any
representations and warranties contained in any other Transaction Document or
any other document or instrument executed and/or delivered in connection with
this Agreement or the consummation of the transaction contemplated
hereby.

    ARTICLE
IV.

    OTHER
AGREEMENTS OF THE PARTIES

     

    4.1     SEC
Reports.  The Company covenants to timely file (or obtain
extensions in respect thereof and file within the applicable grace period) all
SEC Reports required to be filed by the Company after the date hereof pursuant
to the Exchange Act through and including the filing of its Annual Report on
Form 10-K for the fiscal year ending July 31, 2009. As long as any Purchaser
owns Securities, if the Company is not required to file reports pursuant to the
Exchange Act, it will prepare and furnish to the Purchasers and make publicly
available in accordance with Rule 144(c) such information as is required for the
Purchasers to sell the Securities, including without limitation, under Rule
144.

     

    4.2     Integration.  The
Company shall not sell, offer for sale or solicit offers to buy or otherwise
negotiate in respect of any security (as defined in Section 2 of the Securities
Act) that would be integrated with the offer or sale of the Securities for
purposes of the rules and regulations of any Trading Market such that it would
require shareholder approval prior to the closing of such other transaction
unless shareholder approval is obtained before the closing of such subsequent
transaction.

     

    4.3     Securities Laws Disclosure;
Publicity.  The Company shall, by 8:30 a.m. (New York City
time) on the Trading Day immediately following the date hereof, issue a press
release confirming the closing of the transactions contemplated hereby and file
a Current Report on Form 8-K with the Commission which includes the Transaction
Documents as exhibits thereto. The Company confirms that it publicly disclosed
all material, non-public information (if any) delivered to any of the Purchasers
by the Company or any of its subsidiaries, or any of their respective officers,
directors, employees or agents in connection with the transactions contemplated
by the Transaction Documents prior to the date hereof. The Company and each
Purchaser shall consult with each other in issuing any other press releases with
respect to the transactions contemplated hereby, and neither the Company nor any
Purchaser shall issue any such press release nor otherwise make any such public
statement without the prior consent of the Company, with respect to any press
release of any Purchaser, or without the prior consent of each Purchaser, with
respect to any press release of the Company, which consent shall not
unreasonably be withheld or delayed, except if such disclosure is required by
law, in which case the disclosing party shall promptly provide the other party
with prior notice of such public statement or
communication.  Notwithstanding the foregoing, the Company shall not
publicly disclose the name of any Purchaser, or include the name of any
Purchaser in any filing with the Commission or any regulatory agency or Trading
Market, without the prior written consent of such Purchaser, except (a) as
required by federal securities law in connection with the filing of final
Transaction Documents (including signature pages thereto) with the Commission
and (b) to the extent such disclosure is required by law or Trading Market
regulations, in which case the Company shall provide the Purchasers with prior
notice of such disclosure permitted under this clause (b).

     

    4.4     Shareholder Rights
Plan.  No claim will be made or enforced by the Company or,
with the consent of the Company, any other Person, that any Purchaser is an
“Acquiring
Person” under any control share acquisition, business combination, poison
pill (including any distribution under a rights agreement) or similar
anti-takeover plan or arrangement in effect or hereafter adopted by the Company,
or that any Purchaser could be deemed to trigger the provisions of any such plan
or arrangement, by virtue of receiving Securities under the Transaction
Documents or under any other agreement between the Company and any of the
Purchasers.

    4.5     Non-Public
Information.  The Company covenants and agrees that neither it,
nor any other Person acting on its behalf will provide any Purchaser or its
agents or counsel with any information that the Company believes constitutes
material non-public information, unless prior thereto such Purchaser shall have
executed a written agreement with the Company regarding the confidentiality and
use of such information.  The Company understands and confirms that
each Purchaser shall be relying on the foregoing covenant in effecting
transactions in securities of the Company.

     

    4.6     Use of
Proceeds.  The Company shall use the net proceeds from the sale
of the Securities hereunder for repayment of indebtedness and/or working capital
purposes, and shall not use such proceeds for (a) the redemption of any Common
Stock or Common Stock Equivalents or (b) the settlement of any outstanding
litigation.

     

    4.7     Indemnification of
Purchasers.   Subject to the provisions of this Section
4.7, the Company will indemnify and hold each Purchaser and its directors,
officers, shareholders, members, partners, employees and agents (and any other
Persons with a functionally equivalent role of a Person holding such titles
notwithstanding a lack of such title or any other title), each Person who
controls such Purchaser (within the meaning of Section 15 of the Securities Act
and Section 20 of the Exchange Act), and the directors, officers, shareholders,
agents, members, partners or employees (and any other Persons with a
functionally equivalent role of a Person holding such titles notwithstanding a
lack of such title or any other title) of such controlling persons (each, a
“Purchaser
Party”) harmless from any and all losses, liabilities, obligations,
claims, contingencies, damages, costs and expenses, including all judgments,
amounts paid in settlements, court costs and reasonable attorneys’ fees and
costs of investigation that any such Purchaser Party may suffer or incur as a
result of or relating to (a) any breach of any of the representations,
warranties, covenants or agreements made by the Company in this Agreement or in
the other Transaction Documents or (b) any action instituted against a Purchaser
in any capacity, or any of them or their respective Affiliates, by any
stockholder of the Company who is not an Affiliate of such Purchaser, with
respect to any of the transactions contemplated by the Transaction Documents
(unless such action is based upon a breach of such Purchaser’s representations,
warranties or covenants under the Transaction Documents or any agreements or
understandings such Purchaser may have with any such stockholder or any
violations by such Purchaser of state or federal securities laws or any conduct
by such Purchaser which constitutes fraud, gross negligence, willful misconduct
or malfeasance).  If any action shall be brought against any Purchaser
Party in respect of which indemnity may be sought pursuant to this Agreement,
such Purchaser Party shall promptly notify the Company in writing, and the
Company shall have the right to assume the defense thereof with counsel of its
own choosing reasonably acceptable to the Purchaser Party.  Any
Purchaser 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 Purchaser Party except to the extent
that (i) the employment thereof has been specifically authorized by the Company
in writing, (ii) the Company has failed after a reasonable period of time to
assume such defense and to employ counsel or (iii) in such action there is, in
the reasonable opinion of counsel, a material conflict on any material issue
between the position of the Company and the position of such Purchaser Party, in
which case the Company shall be responsible for the reasonable fees and expenses
of no more than one such separate counsel.  The Company will not be
liable to any Purchaser Party under this Agreement (y) for any settlement by a
Purchaser Party effected without the Company’s prior written consent, which
shall not be unreasonably withheld or delayed; or (z) to the extent, but only to
the extent that a loss, claim, damage or liability is attributable to any
Purchaser Party’s breach of any of the representations, warranties, covenants or
agreements made by such Purchaser Party in this Agreement or in the other
Transaction Documents.

    4.8     Listing of Common
Stock. The Company hereby agrees to use best efforts to maintain the
listing or quotation of the Common Stock on the Trading Market on which it is
currently listed, and concurrently with the execution hereof, the Company shall
list or quote all of the Shares and Warrant Shares on such Trading Market and
promptly secure the listing of all of the Shares and Warrant Shares on such
Trading Market no later than the issuance of the initial press release described
in Section 4.3 hereof. The Company further agrees, if the Company applies to
have the Common Stock traded on any other Trading Market, it will then include
in such application all of the Shares and Warrant Shares, and will take such
other action as is necessary to cause all of the Shares and Warrant Shares to be
listed or quoted on such other Trading Market as promptly as
possible.  The Company will then take all action reasonably necessary
to continue the listing and trading of its Common Stock on a Trading Market and
will comply in all respects with the Company’s reporting, filing and other
obligations under the bylaws or rules of the Trading Market.

     

    4.9     Warrant
Shares.  If all or any portion of a Warrant is exercised at a
time when there is an effective registration statement to cover the issuance or
resale of the Warrant Shares or if the Warrant is exercised via cashless
exercise, the Warrant Shares issued pursuant to any such exercise shall be
issued free of all legends.  If at any time following the date hereof
the Registration Statement (or any subsequent registration statement registering
the sale or resale of the Warrant Shares) is not effective or is not otherwise
available for the sale or resale of the Warrant Shares, the Company shall
immediately notify the holders of the Warrants in writing that such registration
statement is not then effective and thereafter shall promptly notify such
holders when the registration statement is effective again and available for the
sale or resale of the Warrant Shares (it being understood and agreed that the
foregoing shall not limit the ability of the Company to issue, or any Purchaser
to sell, any of the Warrant Shares in compliance with applicable federal and
state securities laws).  The Company shall use best efforts to keep a
registration statement (including the Registration Statement) registering the
issuance or resale of the Warrant Shares effective during the term of the
Warrants. Upon a cashless exercise of a Warrant, the holding period for purposes
of Rule 144 shall tack back to the original date of issuance of such
Warrant.

     

    4.10   Equal Treatment of
Purchasers.  No consideration (including any modification of
any Transaction Document) shall be offered or paid to any Person to amend or
consent to a waiver or modification of any provision of any of the Transaction
Documents unless the same consideration is also offered to all of the parties to
the Transaction Documents.  For clarification purposes, this provision
constitutes a separate right granted to each Purchaser by the Company and
negotiated separately by each Purchaser, and is intended for the Company to
treat the Purchasers as a class and shall not in any way be construed as the
Purchasers acting in concert or as a group with respect to the purchase,
disposition or voting of Securities or otherwise.

     

    4.11   Certain Transactions and
Confidentiality. Notwithstanding anything contained in this Agreement to
the contrary, the Company expressly acknowledges and agrees that (i) no
Purchaser makes any representation, warranty or covenant hereby that it will not
engage in effecting transactions in any securities of the Company, (ii) no
Purchaser shall be restricted or prohibited from effecting any transactions in
any securities of the Company in accordance with applicable securities laws and
(iii) no Purchaser shall have any duty of confidentiality to the Company or its
Subsidiaries.

    4.12   Delivery of Warrants After
Closing.  The Company shall deliver, or cause to be delivered,
the respective Warrant certificates purchased by each Purchaser to such
Purchaser within 3 Trading Days of the Closing Date.

     

    ARTICLE

    MISCELLANEOUS

     

    5.1     Termination. 
This Agreement may be terminated by any Purchaser, as to such Purchaser’s
obligations hereunder only and without any effect whatsoever on the obligations
between the Company and the other Purchasers, by written notice to the other
parties, if the Closing has not been consummated on August 6, 2009; provided, however, no such
termination will affect the right of any party to sue for any breach by the
other party (or parties).

     

    5.2     Fees and
Expenses.  Except as expressly set forth in the Transaction
Documents to the contrary, each party shall pay the fees and expenses of its
advisers, counsel, accountants and other experts, if any, and all other expenses
incurred by such party incident to the negotiation, preparation, execution,
delivery and performance of this Agreement.  The Company shall pay all
Transfer Agent fees, stamp taxes and other taxes and duties levied in connection
with the delivery of any Securities to the Purchasers.

     

    5.3     Entire
Agreement.  The Transaction Documents, together with the
exhibits and schedules thereto, and the Prospectus, contain the entire
understanding of the parties with respect to the subject matter hereof and
supersede all prior agreements and understandings, oral or written, with respect
to such subject matter, which the parties acknowledge have been merged into such
documents, exhibits and schedules; provided, however, (i) the foregoing shall
not have any effect on any agreements any Purchaser has entered into with the
Company or any of its Subsidiaries prior to the date hereof with respect to any
prior investment made by such Purchaser in the Company and (ii) nothing
contained in this Agreement or any other Transaction Document shall (or shall be
deemed to) waive, alter, modify or amend in any respect any obligations of the
Company or any of its Subsidiaries or any rights of or benefits to any Purchaser
or any other Person in any agreement entered into prior to the date hereof
between or among the Company and/or any of its Subsidiaries and any Purchaser
and all such agreements shall continue in full force and effect.

     

    5.4     Notices.  Any

be provided hereunder shall be in writing and shall be deemed given and
effective on the earliest of: (a) the date of transmission, if such notice or
communication is delivered via facsimile at the facsimile number set forth on
the signature pages attached hereto prior to 5:30 p.m. (New York City time) on a
Trading Day, (b) the next Trading Day after the date of transmission, if such

or later than 5:30 p.m. (New York City time) on any Trading Day, (c) the second
(2nd)Trading

overnight courier service or (d) upon actual receipt by the party to whom such
notice is required to be given.  The address for such notices and
communications shall be as set forth on the signature pages attached

    5.5     Amendments;
Waivers.  No provision of this Agreement may be waived,
modified, supplemented or amended except in a written instrument signed, in the
case of an amendment, by the Company and the Purchasers holding at least 67% in
interest of the Shares then outstanding or, in the case of a waiver, by the
party against whom enforcement of any such waived provision is
sought.  No waiver of any default with respect to any provision,
condition or requirement of this Agreement shall be deemed to be a continuing
waiver in the future or a waiver of any subsequent default or a waiver of any
other provision, condition or requirement hereof, nor shall any delay or
omission of any party to exercise any right hereunder in any manner impair the
exercise of any such right.

     

    5.6     Headings.  The
headings herein are for convenience only, do not constitute a part of this
Agreement and shall not be deemed to limit or affect any of the provisions
hereof.

     

    5.7     Successors and
Assigns.  This Agreement shall be binding upon and inure to the
benefit of the parties and their successors and permitted
assigns.  The Company may not assign this Agreement or any rights or
obligations hereunder without the prior written consent of each Purchaser (other
than by merger).  Any Purchaser may assign any or all of its rights
under this Agreement to any Person to whom such Purchaser assigns or transfers
at least 25% of the Securities originally purchased by such purchaser, provided
that such transferee agrees in writing to be bound, with respect to the
transferred Securities, by the provisions of the Transaction Documents that
apply to the “Purchasers.”

     

    5.8     No Third-Party
Beneficiaries.  This Agreement is intended for the benefit of
the parties hereto and their respective successors and permitted assigns and is
not for the benefit of, nor may any provision hereof be enforced by, any other
Person, except as otherwise set forth in Section 4.7.

     

    5.9     Governing
Law.  All questions concerning the construction, validity,
enforcement and interpretation of the Transaction Documents shall be governed by
and construed and enforced in accordance with the internal laws of the State of
New York, without regard to the principles of conflicts of law
thereof.  Each party agrees that all legal proceedings concerning the
interpretations, enforcement and defense of the transactions contemplated by
this Agreement and any other Transaction Documents (whether brought against a
party hereto or its respective affiliates, directors, officers, shareholders,
employees or agents) shall be commenced exclusively in the state and federal
courts sitting in the City of New York. Each party hereby irrevocably submits to
the exclusive jurisdiction of the state and federal courts sitting in the City
of New York, borough of Manhattan for the adjudication of any dispute hereunder
or in connection herewith or with any transaction contemplated hereby or
discussed herein (including with respect to the enforcement of any of the
Transaction Documents), and hereby irrevocably waives, and agrees not to assert
in any suit, action or proceeding, any claim that it is not personally subject
to the jurisdiction of any such court, that such suit, action or proceeding is
improper or is an inconvenient venue for such proceeding.  Each party
hereby irrevocably waives personal service of process and consents to process
being served in any such suit, action or proceeding by mailing a copy thereof
via registered or certified mail or overnight delivery (with evidence of
delivery) to such party at the address in effect for notices to it under this
Agreement and agrees that such service shall constitute good and sufficient
service of process and notice thereof.  Nothing contained herein shall
be deemed to limit in any way any right to serve process in any other manner
permitted by law.  If either party shall commence an action or
proceeding to enforce any provisions of the Transaction Documents, then, in
addition to the obligations of the Company under Section 4.7, the prevailing
party in such action or proceeding shall be reimbursed by the other party for
its reasonable attorneys’ fees and other costs and expenses incurred with the
investigation, preparation and prosecution of such action or
proceeding.

    5.10   Survival.  The
representations and warranties contained herein shall survive the Closing and
the delivery of the Shares.

     

    5.11   Execution.  This
Agreement may be executed in two or more counterparts, all of which when taken
together shall be considered one and the same agreement and shall become
effective when counterparts have been signed by each party and delivered to the
other party, it being understood that both parties need not sign the same
counterpart.  In the event that any signature is delivered by
facsimile transmission or by e-mail delivery of a “.pdf” format data file, such
signature shall create a valid and binding obligation of the party executing (or
on whose behalf such signature is executed) with the same force and effect as if
such facsimile or “.pdf” signature page were an original thereof.

     

    5.12   Severability.  If
any term, provision, covenant or restriction of this Agreement is held by a
court of competent jurisdiction to be invalid, illegal, void or unenforceable,
the remainder of the terms, provisions, covenants and restrictions set forth
herein shall remain in full force and effect and shall in no way be affected,
impaired or invalidated, and the parties hereto shall use their commercially
reasonable efforts to find and employ an alternative means to achieve the same
or substantially the same result as that contemplated by such term, provision,
covenant or restriction. It is hereby stipulated and declared to be the
intention of the parties that they would have executed the remaining terms,
provisions, covenants and restrictions without including any of such that may be
hereafter declared invalid, illegal, void or unenforceable.

     

    5.13   Rescission and Withdrawal
Right.  Notwithstanding anything to the contrary contained in
(and without limiting any similar provisions of) any of the other Transaction
Documents, whenever any Purchaser exercises a right, election, demand or option
under a Transaction Document and the Company does not timely perform its related
obligations within the periods therein provided, then such Purchaser may rescind
or withdraw, in its sole discretion from time to time upon written notice to the
Company, any relevant notice, demand or election in whole or in part without
prejudice to its future actions and rights; provided, however, in the case
of a rescission of an exercise of a Warrant, the applicable Purchaser shall be
required to return any shares of Common Stock subject to any such rescinded
exercise notice concurrently with the return to such Purchaser of the aggregate
exercise price paid to the Company for such shares and the restoration of such
Purchaser’s right to acquire such shares pursuant to such Purchaser’s Warrant
(including, issuance of a replacement warrant certificate evidencing such
restored right).


    
      
         


      

      
        23

        
          

        

      

      
         


      

    


    5.14   Replacement of
Securities.  If any certificate or instrument evidencing any
Securities is mutilated, lost, stolen or destroyed, the Company shall issue or
cause to be issued in exchange and substitution for and upon cancellation
thereof (in the case of mutilation), or in lieu of and substitution therefor, a
new certificate or instrument, but only upon receipt of evidence reasonably
satisfactory to the Company of such loss, theft or destruction.  The
applicant for a new certificate or instrument under such circumstances shall
also pay any reasonable third-party costs (including customary indemnity)
associated with the issuance of such replacement Securities.

     

    5.15   Remedies.  In
addition to being entitled to exercise all rights provided herein or granted by
law, including recovery of damages, each of the Purchasers and the Company will
be entitled to specific performance under the Transaction
Documents.  The parties agree that monetary damages may not be
adequate compensation for any loss incurred by reason of any breach of
obligations contained in the Transaction Documents and hereby agree to waive and
not to assert in any action for specific performance of any such obligation the
defense that a remedy at law would be adequate.

     

    5.16   Payment Set
Aside.  To the extent that the Company makes a payment or
payments to any Purchaser pursuant to any Transaction Document or a Purchaser
enforces or exercises its rights thereunder, and such payment or payments or the
proceeds of such enforcement or exercise or any part thereof are subsequently
invalidated, declared to be fraudulent or preferential, set aside, recovered
from, disgorged by or are required to be refunded, repaid or otherwise restored
to the Company, a trustee, receiver or any other person under any law
(including, without limitation, any bankruptcy law, state or federal law, common
law or equitable cause of action), then to the extent of any such restoration
the obligation or part thereof originally intended to be satisfied shall be
revived and continued in full force and effect as if such payment had not been
made or such enforcement or setoff had not occurred.

     

    5.17   Independent Nature of
Purchasers’ Obligations and Rights.  The obligations of each
Purchaser under any Transaction Document are several and not joint with the
obligations of any other Purchaser, and no Purchaser shall be responsible in any
way for the performance or non-performance of the obligations of any other
Purchaser under any Transaction Document.  Nothing contained herein or
in any other Transaction Document, and no action taken by any Purchaser pursuant
thereto, shall be deemed to constitute the Purchasers as a partnership, an
association, a joint venture or any other kind of entity, or create a
presumption that the Purchasers are in any way acting in concert or as a group
with respect to such obligations or the transactions contemplated by the
Transaction Documents.  Each Purchaser shall be entitled to
independently protect and enforce its rights including, without limitation, the
rights arising out of this Agreement or out of the other Transaction Documents,
and it shall not be necessary for any other Purchaser to be joined as an
additional party in any proceeding for such purpose.  Each Purchaser
has been represented by its own separate legal counsel in their review and
negotiation of the Transaction Documents.  The Company has elected to
provide all Purchasers with the same terms and Transaction Documents for the
convenience of the Company and not because it was required or requested to do so
by any of the Purchasers.  It is expressly understood and agreed that
each provision contained in this Agreement and in each other Transaction
Document is between the Company and a Purchaser, solely, and not between the
Company and the Purchasers collectively and not between and among the
Purchasers.

     

    5.18   Liquidated
Damages.  The Company’s obligations to pay any partial
liquidated damages or other amounts owing under the Transaction Documents is a
continuing obligation of the Company and shall not terminate until all unpaid
partial liquidated damages and other amounts have been paid notwithstanding the
fact that the instrument or security pursuant to which such partial liquidated
damages or other amounts are due and payable shall have been
canceled.


    
      
         


      

      
        24

        
          

        

      

      
         


      

    


    5.19   Saturdays, Sundays,
Holidays, etc.      If the last or
appointed day for the taking of any action or the expiration of any right
required or granted herein shall not be a Business Day, then such action may be
taken or such right may be exercised on the next succeeding Business
Day.

     

    5.20   Construction. The
parties agree that each of them and/or their respective counsel has reviewed and
had an opportunity to revise the Transaction Documents and, therefore, the
normal rule of construction to the effect that any ambiguities are to be
resolved against the drafting party shall not be employed in the interpretation
of the Transaction Documents or any amendments hereto. In addition, each and
every reference to share prices and shares of Common Stock in any Transaction
Document shall be subject to adjustment for reverse and forward stock splits,
stock dividends, stock combinations and other similar transactions of the Common
Stock that occur after the date of this Agreement.

     

    5.21   WAIVER OF
JURY TRIAL.  IN ANY
ACTION, SUIT, OR PROCEEDING IN ANY JURISDICTION BROUGHT BY ANY PARTY AGAINST ANY
OTHER PARTY, THE PARTIES EACH KNOWINGLY AND INTENTIONALLY, TO THE GREATEST
EXTENT PERMITTED BY APPLICABLE LAW, HEREBY ABSOLUTELY, UNCONDITIONALLY,
IRREVOCABLY AND EXPRESSLY WAIVES FOREVER TRIAL BY JURY.
