Exhibit  A  hereto   (individually,   a  "Purchaser"   and   collectively,   the
"Purchasers").
      The parties hereto agree as follows:
                                   ARTICLE I
                      Purchase and Sale of Preferred Stock
            Section 1.1 Purchase and Sale of Stock. Upon the following terms and
conditions,  the Company shall issue and sell to the  Purchasers and each of the
Purchasers  shall purchase from the Company,  6,668,230  shares of the Company's
Series A Convertible  Preferred Stock, par value $0.01 per share (the "Preferred

of the Company's  common stock,  par value $0.01 per share (the "Common Stock"),
in the amounts set forth opposite such Purchaser's name on Exhibit A hereto. The
designation,  rights, preferences and other terms and provisions of the Series A
Convertible  Preferred  Stock are set forth in the Certificate of Designation of
the Relative Rights and Preferences of the Series A Convertible  Preferred Stock
attached hereto as Exhibit B (the "Certificate of Designation"). The Company and
the Purchasers are executing and  delivering  this Agreement in accordance  with
and in reliance upon the exemption from securities registration afforded by Rule
506 of  Regulation  D  ("Regulation  D") as  promulgated  by the  United  States
Securities and Exchange  Commission (the "Commission")  under the Securities Act
of 1933,  as amended (the  "Securities  Act") or Section 4(2) of the  Securities
Act.
            Section 1.2 Warrants.  Upon the following  terms and  conditions and
for no  additional  consideration,  each of the  Purchasers  shall be issued (i)
Series A Warrants, in substantially the form attached hereto as Exhibit C-1 (the
"Series A Warrants"),  to purchase 6,668,230 shares of Common Stock, (ii) Series
B  Warrants,  in  substantially  the form  attached  hereto as Exhibit  C-2 (the

that such Purchaser  purchases Preferred Shares for a purchase price equal to or
greater than $5,000,000  pursuant to the terms of this  Agreement,  as set forth
opposite such Purchaser's name on Exhibit A hereto,  and, provided further that,
the  terms  of  exercise  of the  Series J  Warrants  (along  with the  Series C
Warrants)  shall be at an amount  twenty  percent (20%) higher than the terms of
conversion of the Series A and Series B Warrants and (iv) Series C Warrants,  in
substantially  the form attached  hereto as Exhibit C-4, shall be issued to such
Purchaser  to  purchase   5,975,116  shares  of  Common  Stock  (the  "Series  C

the extent the Series J Warrant has been exercised  (the Series A Warrants,  the
Series B  Warrants,  the  Series J  Warrants  and the  Series C  Warrants  shall
collectively be known herein as, the "Warrants"). The Warrants shall expire five

authorized  and has  reserved  and  covenants  to continue  to reserve,  free of

Company  filing the Charter  Amendment (as defined in Section 3.23 hereof),  the
Company shall authorize and reserve and continue to reserve,  free of preemptive
rights and other similar contractual rights of stockholders,  a number of shares
of Common  Stock  equal to one  hundred  fifty  percent  (150%) of the number of
shares of Common  Stock as shall from time to time be  sufficient  to effect the
conversion  of all of the  Preferred  Shares and exercise of the  Warrants  then
outstanding.  Any  shares  of  Common  Stock  issuable  upon  conversion  of the
Preferred  Shares and exercise of the Warrants (and such shares when issued) are
herein  referred  to as  the  "Conversion  Shares"  and  the  "Warrant  Shares",
respectively. The Preferred Shares, the Conversion Shares and the Warrant Shares
are sometimes  collectively  referred to as the  "Shares".
            Section 1.4  Purchase  Price and  Closing.  Subject to the terms and
conditions  hereof,  the Company agrees to issue and sell to the Purchasers and,
in  consideration   of  and  in  express  reliance  upon  the   representations,

                                   ARTICLE II
                         Representations and Warranties
            Section 2.1  Representations  and  Warranties  of the  Company.  The
Company hereby represents and warrants to the Purchasers,  as of the date hereof
and the Closing Date (except as set forth on the Schedule of Exceptions attached

as  follows:
                                       2
            (a)  Organization,  Good  Standing  and  Power.  The  Company  is  a
corporation duly  incorporated,  validly existing and in good standing under the
laws of the State of Nevada and has the requisite  corporate power to own, lease
and operate its  properties  and assets and to conduct its business as it is now
being conducted.  The Company does not have any subsidiaries except as set forth
in  Schedule  2.1(a)  hereof.  The  Company  and each  such  subsidiary  is duly
qualified as a foreign  corporation  to do business  and is in good  standing in
every  jurisdiction  in which the nature of the  business  conducted or property
owned by it makes such  qualification  necessary except for any  jurisdiction(s)
(alone or in the  aggregate)  in which the failure to be so  qualified  will not
have a Material  Adverse  Effect (as  defined in Section  2.1(c)  hereof) on the
Company's financial condition.
            (b)  Authorization;  Enforcement.  The  Company  has  the  requisite
corporate  power and  authority  to enter into and perform this  Agreement,  the
Registration  Rights  Agreement  in the form  attached  hereto as Exhibit D (the
"Registration  Rights Agreement"),  the Lock-Up Agreement (as defined in Section
3.20 hereof) in the form attached  hereto as Exhibit E, the Escrow  Agreement by
and among the Company, the Purchasers and the escrow agent, dated as of the date

3.13),  the  Certificate of  Designation,  and the Warrants  (collectively,  the
"Transaction  Documents")  and to issue and sell the Shares and the  Warrants in
accordance with the terms hereof. The execution, delivery and performance of the
Transaction  Documents  by  the  Company  and  the  consummation  by it  of  the
transactions  contemplated  hereby  and  thereby  have  been  duly  and  validly
authorized  by all  necessary  corporate  action,  and  no  further  consent  or
authorization  of the  Company  or its Board of  Directors  or  stockholders  is
required.  This  Agreement  has been duly executed and delivered by the Company.
The other  Transaction  Documents  will have been duly executed and delivered by
the Company at the Closing.  Each of the Transaction Documents  constitutes,  or
shall constitute when executed and delivered,  a valid and binding obligation of
the Company enforceable against the Company in accordance with its terms, except
as such  enforceability  may be limited by  applicable  bankruptcy,  insolvency,
reorganization,   moratorium,  liquidation,  conservatorship,   receivership  or
similar laws relating to, or affecting  generally the enforcement of, creditor's
rights and remedies or by other equitable principles of general application.
            (c) Capitalization.  The authorized capital stock of the Company and
the shares thereof  currently  issued and  outstanding as of the date hereof are
set forth on Schedule 2.1(c) hereto. All of the outstanding shares of the Common

set forth on Schedule  2.1(c) hereto,  no shares of Common Stock are entitled to
preemptive rights or registration  rights and there are no outstanding  options,
warrants,  scrip,  rights to subscribe to, call or  commitments of any character
whatsoever  relating to, or securities or rights convertible into, any shares of
capital   stock  of  the   Company.   There  are  no   contracts,   commitments,
understandings,  or  arrangements by which the Company is or may become bound to
issue  additional  shares  of the  capital  stock  of the  Company  or  options,
securities  or rights  convertible  into shares of capital stock of the Company.
Except  as  set  forth  on  Schedule  2.1(c)  hereto,  or  contemplated  by  the
Transaction  Documents,  the  Company is not a party to any  agreement  granting
registration  or  anti-dilution  rights to any person with respect to any of its
equity  or  debt  securities.  The  Company  is not a  party  to,  and it has no
knowledge of, any agreement  restricting the voting or transfer of any shares of
the capital
                                       3
stock of the Company,  except for the Transaction Documents.  The offer and sale
of all capital stock,  convertible securities,  rights,  warrants, or options of
the Company issued prior to the Closing complied with all applicable Federal and
state securities laws, and no stockholder has a right of rescission or claim for
damages  with respect  thereto  which would have a Material  Adverse  Effect (as
defined  below).  The Company has furnished or made  available to the Purchasers
true and correct copies of the Company's  Articles of Incorporation as in effect
on the date hereof (the  "Articles"),  and the Company's  Bylaws as in effect on
the date hereof (the "Bylaws").  For the purposes of this  Agreement,  "Material
Adverse Effect" means any material  adverse effect on the business,  operations,
properties,   prospects,   or  financial   condition  of  the  Company  and  its
subsidiaries  and/or  any  condition,  circumstance,  or  situation  that  would
prohibit or otherwise  materially  interfere  with the ability of the Company to
perform any of its obligations under this Agreement in any material respect,  or
to conduct its business in the ordinary course.
            (d) Issuance of Shares.  The Preferred Shares and the Warrants to be
issued at the  Closing  have been duly  authorized  by all  necessary  corporate
action and the Preferred Shares,  when paid for or issued in accordance with the
terms  hereof,  shall  be  validly  issued  and  outstanding,   fully  paid  and
nonassessable  and  entitled  to the  rights  and  preferences  set forth in the
Certificate of  Designation.  When the Conversion  Shares and the Warrant Shares
are issued in accordance  with the terms of the  Certificate of Designation  and
the Warrants, respectively, such shares will be duly authorized by all necessary
corporate   action  and  validly   issued  and   outstanding,   fully  paid  and
nonassessable,  and the holders  shall be  entitled to all rights  accorded to a
holder  of  Common  Stock.
            (e) No Conflicts.  The  execution,  delivery and  performance of the
Transaction  Documents by the  Company,  the  performance  by the Company of its
obligations  under the  Certificate of Designation  and the  consummation by the
Company of the transactions  contemplated herein and therein do not and will not
(i) violate any  provision of the  Company's  Articles or Bylaws,  (ii) conflict
with, or constitute a default (or an event which with notice or lapse of time or
both would become a default) under, or give to others any rights of termination,
amendment,  acceleration or cancellation  of, any agreement,  mortgage,  deed of
trust, indenture, note, bond, license, lease agreement, instrument or obligation
to which the Company is a party or by which it or its  properties  or assets are
bound, (iii) create or impose a lien,  mortgage,  security  interest,  charge or
encumbrance  of any nature on any property of the Company under any agreement or
any  commitment to which the Company is a party or by which the Company is bound
or by which any of its respective properties or assets are bound, or (iv) result
in  a  violation  of  any  federal,  state,  local  or  foreign  statute,  rule,
regulation,  order,  judgment or decree (including  Federal and state securities
laws and regulations  assuming the representations made by the Purchasers herein
are true and correct) applicable to the Company or any of its subsidiaries or by
which any property or asset of the Company or any of its  subsidiaries are bound
or affected,  except, in all cases other than violations pursuant to clauses (i)
and  (iv)  above,  for  such  conflicts,  defaults,  terminations,   amendments,
accelerations, cancellations and violations as would not, individually or in the
aggregate,  have a Material Adverse Effect.  The business of the Company and its
subsidiaries  is not being  conducted in violation  of any laws,  ordinances  or
regulations of any  governmental  entity,  except for possible  violations which
singularly  or in the  aggregate  do not and will not  have a  Material  Adverse
Effect. The Company is not required
                                       4
under  Federal,  state or local law,  rule or  regulation to obtain any consent,
authorization or order of, or make any filing or registration with, any court or
governmental  agency in order for it to  execute,  deliver or perform any of its
obligations  under the  Transaction  Documents,  or issue and sell the Preferred
Shares, the Warrants, the Conversion Shares and the Warrant Shares in accordance
with the terms hereof or thereof  (other than any filings  which may be required
to be made by the Company with the Commission or state securities administrators
subsequent  to the  Closing,  any  registration  statement  which  may be  filed
pursuant hereto, the Certificate of Designation and any other filings to be made
with  the  Nevada  Secretary  of State or as  would  not be  expected  to have a
Material Adverse Effect).
            (f) Commission Documents,  Financial Statements.  At the time of the
Closing the Common Stock shall be registered  pursuant to Section 12(b) or 12(g)
of the  Securities  Exchange Act of 1934,  as amended the "Exchange  Act").  The
Company has not provided to the Purchasers any material  non-public  information
or other information which, according to applicable law, rule or regulation, was
required to have been  disclosed  publicly by the Company but which has not been
so disclosed,  other than with respect to the transactions  contemplated by this
Agreement.  The financial  statements of the Company  provided to the Purchasers
(the "Financial Statements") were true and accurate and contain no misstatements
of  material  fact,  except as would not have a Material  Adverse  Effect.  Such
Financial  Statements  have been  prepared  in  accordance  with  United  States
generally accepted accounting  principles ("GAAP") applied on a consistent basis
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 not  include  footnotes  or may be
condensed or summary  statements),  and fairly present in all material  respects
the  financial  position  of the Company  and its  subsidiaries  as of the dates
thereof and the results of operations  and cash flows for the periods then ended
(subject,  in the  case  of  unaudited  statements,  to  normal  year-end  audit
adjustments).
            (g) Subsidiaries.  Schedule 2.1(g) hereto sets forth each subsidiary
of the Company,  showing the  jurisdiction of its  incorporation or organization
and showing the percentage of each person's ownership.  For the purposes of this
Agreement,  "subsidiary"  shall mean any corporation or other entity of which at
least a majority of the securities or other  ownership  interest having ordinary
voting power (absolutely or contingently) for the election of directors or other
persons  performing  similar  functions  are  at  the  time  owned  directly  or
indirectly  by the  Company  and/or  any of its other  subsidiaries.  All of the
outstanding shares of capital stock of each subsidiary have been duly authorized
and  validly  issued,  and  are  fully  paid  and  nonassessable.  There  are no
outstanding  preemptive,  conversion  or  other  rights,  options,  warrants  or
agreements  granted or issued by or binding upon any subsidiary for the purchase
or  acquisition  of any shares of capital  stock of any  subsidiary or any other
securities  convertible  into,  exchangeable  for or  evidencing  the  rights to
subscribe  for any shares of such  capital  stock.  Neither  the Company nor any
subsidiary is subject to any obligation  (contingent or otherwise) to repurchase
or otherwise acquire or retire any shares of the capital stock of any subsidiary
or any convertible securities, rights, warrants or options of the type described
in the preceding  sentence.  Neither the Company nor any subsidiary is party to,
nor has any knowledge of, any  agreement  restricting  the voting or transfer of
any shares of the capital stock of any subsidiary.
            (h) No Material Adverse Change. Since December 31, 2006, the Company
                                       5
has not experienced or suffered any Material Adverse Effect.
            (i) No Undisclosed  Liabilities.  Neither the Company nor any of its
subsidiaries  has  any  liabilities,  obligations,  claims  or  losses  (whether
liquidated or unliquidated,  secured or unsecured, absolute, accrued, contingent
or otherwise)  other than those incurred in the ordinary course of the Company's
or its  subsidiaries  respective  businesses  since December 31, 2006 and which,
individually  or in the aggregate,  do not or would not have a Material  Adverse
Effect on the Company or its subsidiaries.
            (j) No Undisclosed  Events or Circumstances.  Except as set forth on
Schedule 2.1(j), no event or circumstance has occurred or exists with respect to
the Company or its  subsidiaries  or their  respective  businesses,  properties,
prospects,  operations or financial condition, which, under applicable law, rule
or regulation,  requires  public  disclosure or  announcement by the Company but
which has not been so publicly announced or disclosed to the Purchasers.
            (k) Indebtedness.  Schedule 2.1(k) hereto sets forth as of March 31,
2007, 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"  shall mean (a) any liabilities for
borrowed money or amounts owed in excess of $100,000  (other than trade accounts
payable  incurred  in the  ordinary  course of  business),  (b) 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 (c) the present value of any lease payments in
excess of $25,000 due under leases required to be capitalized in accordance with
GAAP.  Except as set forth on  Schedule  2.1(k),  neither  the  Company  nor any
subsidiary is in default with respect to any Indebtedness.
            (l) Title to Assets.  Each of the Company and the  subsidiaries  has
good and marketable title to all of its real and personal property  reflected in
Schedule  2.1(l),  free and clear of any  mortgages,  pledges,  charges,  liens,
security interests or other encumbrances, except for those disclosed in Schedule
2.1(l) or such that,  individually or in the aggregate,  do not cause a Material
Adverse Effect. All leases of the Company and each of its subsidiaries are valid
and subsisting and in full force and effect.
            (m) Actions Pending.  Except as disclosed on Schedule 2.1(m),  there
is  no  action,  suit,  claim,  investigation,  arbitration,  alternate  dispute
resolution  proceeding or any other  proceeding  pending or, to the knowledge of
the Company,  threatened  against the Company or any subsidiary  which questions
the validity of this Agreement or any of the other Transaction  Documents or the
transactions  contemplated  hereby or thereby or any action taken or to be taken

pending or, to the  knowledge of the Company,  threatened,  against or involving
the Company,  any  subsidiary or any of their  respective  properties or assets.
There are no outstanding orders,  judgments,  injunctions,  awards or decrees of

            (n)  Compliance  with  Law.  The  business  of the  Company  and the
subsidiaries  has been and is presently  being  conducted in accordance with all
applicable  federal,  state and local governmental laws, rules,  regulations and
ordinances,   except  for  such  noncompliance  that,  individually  or  in  the
aggregate,  would not cause a Material  Adverse Effect.  The Company and each of
its  subsidiaries  have all franchises,  permits,  licenses,  consents and other
governmental  or  regulatory  authorizations  and  approvals  necessary  for the
conduct of its  business  as now being  conducted  by it unless  the  failure to
possess such franchises,  permits, licenses,  consents and other governmental or
regulatory authorizations and approvals, individually or in the aggregate, could
not reasonably be expected to have a Material Adverse Effect.
            (o) Taxes.  Except as disclosed on Schedule 2.1(o),  the Company and
each of the  subsidiaries has accurately  prepared and filed all federal,  state
and  other  tax  returns  required  by law to be filed  by it,  has paid or made
provisions  for the  payment  of all  taxes  shown to be due and all  additional

financial  statements of the Company and the  subsidiaries for all current taxes
and other  charges to which the Company or any  subsidiary  is subject and which
are not currently due and payable. None of the federal income tax returns of the
Company or any subsidiary have been audited by the Internal Revenue Service. The
Company  has  no  knowledge  of  any  additional  assessments,   adjustments  or
contingent tax liability  (whether  federal or state) of any nature  whatsoever,
whether  pending or  threatened  against the Company or any  subsidiary  for any
period, nor of any basis for any such assessment, adjustment or contingency.
            (p)  Certain  Fees.  Except  for the fees  being  paid to SC Capital
Partners,  LLC in  connection  with the  transactions  contemplated  hereby,  no
brokers,  finders or financial  advisory fees or commissions  will be payable by
the Company or any subsidiary or any Purchaser with respect to the  transactions
contemplated by this Agreement.
            (q) Disclosure.  Neither this Agreement or the Schedules  hereto nor
any other documents,  certificates or instruments furnished to the Purchasers by
or  on  behalf  of  the  Company  or  any  subsidiary  in  connection  with  the
transactions  contemplated by this Agreement  contain any untrue  statement of a
material  fact or omit to state a material  fact  necessary in order to make the
statements made herein or therein, in the light of the circumstances under which
they were made herein or therein, not misleading.
            (r) Operation of Business.  The Company and each of the subsidiaries
owns  or  possesses  all  patents,  trademarks,  domain  names  (whether  or not
registered) and any patentable  improvements or  copyrightable  derivative works
thereof,  websites and intellectual  property rights relating  thereto,  service
marks,  trade names,  copyrights,  licenses and  authorizations  as set forth in
Schedule  2.1(r),  and all  rights  with  respect  to the  foregoing,  which are
necessary for the conduct of its business as now conducted  without any conflict
with the rights of others.
            (s)   Environmental   Compliance.   The  Company  and  each  of  its
subsidiaries
                                       7
have obtained all material  approvals,  authorization,  certificates,  consents,
licenses, orders and permits or other similar authorizations of all governmental
authorities, or from any other person, that are required under any Environmental
Laws.  Schedule  2.1(s)  describes  all  material  permits,  licenses  and other
authorizations  issued  under  any  Environmental  Laws  to the  Company  or its
subsidiaries.  "Environmental  Laws" shall mean all applicable  laws relating to
the  protection  of  the  environment   including,   without   limitation,   all
requirements  pertaining  to  reporting,  licensing,  permitting,   controlling,
investigating  or  remediating  emissions,  discharges,  releases or  threatened
releases of hazardous substances, chemical substances, pollutants,  contaminants
or toxic substances,  materials or wastes,  whether solid,  liquid or gaseous in
nature,  into the air,  surface  water,  groundwater or land, or relating to the
manufacture,   processing,  distribution,  use,  treatment,  storage,  disposal,
transport or handling of hazardous substances, chemical substances,  pollutants,
contaminants or toxic substances,  material or wastes,  whether solid, liquid or
gaseous in nature. The Company has all necessary governmental approvals required
under all Environmental  Laws and used in its business or in the business of any
of its  subsidiaries.  The  Company  and  each of its  subsidiaries  are also in
compliance  with all other  limitations,  restrictions,  conditions,  standards,
requirements,   schedules   and   timetables   required  or  imposed  under  all
Environmental  Laws.  Except for such instances as would not  individually or in
the  aggregate  have a  Material  Adverse  Effect,  there are no past or present
events, conditions,  circumstances,  incidents, actions or omissions relating to
or in any way  affecting  the Company or its  subsidiaries  that  violate or may
violate any  Environmental  Law after the Closing  Date or that may give rise to
any environmental  liability,  or otherwise form the basis of any claim, action,
demand,  suit,  proceeding,  hearing,  study  or  investigation  (i)  under  any
Environmental  Law, or (ii) based on or related to the manufacture,  processing,
distribution,  use, treatment, storage (including without limitation underground
storage tanks),  disposal,  transport or handling,  or the emission,  discharge,
release or threatened release of any hazardous substance.
            (t) Books and Record  Internal  Accounting  Controls.  The books and
records of the Company and its subsidiaries  accurately  reflect in all material
respects  the  information  relating  to the  business  of the  Company  and the
subsidiaries, the location and collection of their assets, and the nature of all
transactions  giving  rise to the  obligations  or  accounts  receivable  of the
Company or any subsidiary.  The Company and each of its subsidiaries  maintain a
system of  internal  accounting  controls  sufficient,  in the  judgment  of the
Company,  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
actions is taken with respect to any differences.
            (u) Material Agreements.  Except as set forth on Schedule 2.1(u) and
the Transaction Documents themselves,  neither the Company nor any subsidiary is
a party to any  written or oral  contract,  instrument,  agreement,  commitment,
obligation,  plan or arrangement,  a copy of which would be required to be filed
with the  Commission  as an exhibit to a  registration  statement on Form S-3 or
applicable  form  (collectively,  "Material  Agreements")  if the Company or any
subsidiary were registering securities under the Securities Act. The Company and
each  of its  subsidiaries  has in  all  material  respects  performed  all  the
obligations  required  to be  performed
                                       8
by them to date  under the  foregoing  agreements,  have  received  no notice of
default and are not in default under any Material  Agreement now in effect,  the
result of which  could  cause a  Material  Adverse  Effect.  No  written or oral
contract, instrument, agreement, commitment,  obligation, plan or arrangement of
the Company or of any subsidiary  limits or shall limit the payment of dividends
on the Company's Preferred Shares,  other preferred stock, if any, or its Common
Stock, except for the Transaction Documents.
            (v) Transactions  with  Affiliates.  Except as set forth on Schedule
2.1(v)  hereof,  there  are no loans,  leases,  agreements,  contracts,  royalty
agreements,   management   contracts  or   arrangements   or  other   continuing
transactions  between (a) the Company or any subsidiary on the one hand, and (b)
on the other hand, any officer, employee, consultant or director of the Company,
or any of its  subsidiaries,  or any  person  owning  any  capital  stock of the
Company or any subsidiary or any member of the immediate family of such officer,
employee, consultant, director or stockholder or any corporation or other entity
controlled by such officer, employee, consultant,  director or stockholder, or a
member of the immediate family of such officer, employee,  consultant,  director
or stockholder.
            (w)  Securities  Act of  1933.  Based  in  material  part  upon  the
representations  herein of the  Purchasers,  the Company has  complied  and will
comply with all applicable  federal and state securities laws in connection with
the offer,  issuance and sale of the Shares and the Warrants hereunder.  Neither
the Company nor anyone acting on its behalf, directly or indirectly, has or will
sell, offer to sell or solicit offers to buy any of the Shares,  the Warrants or
similar  securities  to, or solicit  offers with respect  thereto from, or enter
into any preliminary  conversations  or negotiations  relating thereto with, any
person,  or has taken or will take any  action so as to bring the  issuance  and
sale of any of the Shares and the Warrants under the registration  provisions of
the Securities Act and applicable state securities laws, and neither the Company
nor any of its  affiliates,  nor any person acting on its or their  behalf,  has
engaged in any form of general  solicitation or general  advertising (within the
meaning of Regulation D under the Securities  Act) in connection  with the offer
or sale of any of the Shares and the Warrants.
            (x)  Governmental  Approvals.  Except  for the  filing of any notice
prior or  subsequent to the Closing Date that may be required  under  applicable
state and/or  Federal  securities  laws (which if required,  shall be filed on a
timely basis),  including the filing of a Form D and a registration statement or
statements pursuant to the Registration Rights Agreement,  and the filing of the
Certificate of Designation and other filings with the Secretary of State for the
State of Nevada, no authorization,  consent,  approval,  license,  exemption of,
filing or registration  with any court or governmental  department,  commission,
board,  bureau,  agency or  instrumentality,  domestic or foreign, is or will be
necessary for, or in connection with, the execution or delivery of the Preferred
Shares  and  the  Warrants,  or  for  the  performance  by  the  Company  of its
obligations under the Transaction Documents.
            (y) Employees.  Except as set forth on Schedule 2.1(y),  neither the
Company  nor  any  subsidiary  has any  collective  bargaining  arrangements  or
agreements  covering  any of its  employees.  Except  as set  forth on  Schedule
2.1(y),  neither the Company nor any  subsidiary  has any  employment  contract,
agreement  regarding   proprietary   information,   non-competition   agreement,
non-solicitation  agreement,  confidentiality  agreement,  or any other  similar
contract
                                       9
or  restrictive  covenant,  relating  to the right of any  officer,  employee or
consultant  to be  employed  or engaged by the  Company or such  subsidiary.  No
officer,  consultant  or key  employee  of the Company or any  subsidiary  whose
termination,  either  individually  or in the  aggregate,  could have a Material
Adverse  Effect,  has  terminated  or, to the knowledge of the Company,  has any
present  intention of terminating  his or her employment or engagement  with the
Company or any subsidiary.
            (z) Absence of Certain Developments. Except as disclosed on Schedule
2.1(z), since December 31, 2006, neither the Company nor any subsidiary has:
                  (i) issued any stock,  bonds or other corporate  securities or

                  (ii) borrowed any amount or incurred or become  subject to any

comparable  portion of its prior fiscal year, as adjusted to reflect the current
nature and volume of the Company's or such subsidiary's business;
                  (iii)  discharged or satisfied any lien or encumbrance or paid

any of the foregoing actions.
            (aa)  Investment  Company Act Status.  The Company is not,  and as a
result of and immediately upon the Closing will not be, an "investment  company"
or a company "controlled" by an "investment  company," within the meaning of the
Investment Company Act of 1940, as amended.
            (bb) ERISA. No liability to the Pension Benefit Guaranty Corporation
has been incurred with respect to any Plan (as defined  below) by the Company or
any of its subsidiaries  which is or would be materially  adverse to the Company
and its  subsidiaries.  The  execution  and delivery of this  Agreement  and the
issuance and sale of the Preferred Shares will not involve any transaction which
is subject to the  prohibitions  of Section 406 of ERISA or in  connection  with
which a tax could be imposed  pursuant to Section 4975 of the  Internal  Revenue
Code of 1986, as amended, provided that, if any of the Purchasers, or any person
or entity  that  owns a  beneficial  interest  in any of the  Purchasers,  is an
"employee  pension  benefit  plan" (within the meaning of Section 3(2) of ERISA)
with respect to which the Company is a "party in  interest"  (within the meaning
of Section 3(14) of ERISA), the requirements of Sections 407(d)(5) and 408(e) of
ERISA, if applicable,  are met. As used in this Section 2.1(ac), the term "Plan"
shall mean an "employee pension benefit plan" (as defined in Section 3 of ERISA)
which is or has been established or maintained, or to which contributions are or
have been made,  by the Company or any  subsidiary  or by any trade or business,
whether or not incorporated, which, together with the Company or any subsidiary,
is under common control, as described in Section 414(b) or (c) of the Code.
            (cc) Dilutive Effect. The Company  understands and acknowledges that
its  obligation  to issue  Conversion  Shares upon  conversion  of the Preferred
Shares in accordance  with this Agreement and the Certificate of Designation and
its obligations to issue the Warrant Shares upon the exercise of the Warrants in
accordance with this Agreement and the Warrants,  is, in each case, absolute and
unconditional  regardless of the dilutive  effect that such issuance may have on
the ownership interest of other stockholders of the Company.
                                       11
            (dd) No  Integrated  Offering.  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 the offering of the Shares
pursuant to this Agreement to be integrated  with prior offerings by the Company
for purposes of the  Securities Act which would prevent the Company from selling
the Shares  pursuant to Rule 506 under the  Securities  Act,  or any  applicable
exchange-related stockholder approval provisions, nor will the Company or any of
its  affiliates  or  subsidiaries  take any action or steps that would cause the
offering of the Shares to be integrated with other  offerings.  The Company does
not have any registration  statement  pending before the Commission or currently
under the  Commission's  review and since  January 1, 2007,  the Company has not
offered or sold any of its equity securities or debt securities convertible into
shares of Common Stock.
            (ee) Independent Nature of Purchasers. The Company acknowledges that
the obligations of each Purchaser  under the  Transaction  Documents are several
and not joint with the  obligations  of any other  Purchaser,  and no  Purchaser
shall be  responsible in any way for the  performance of the  obligations of any
other Purchaser under the Transaction  Documents.  The Company acknowledges that
the decision of each Purchaser to purchase securities pursuant to this Agreement
has  been  made  by such  Purchaser  independently  of any  other  purchase  and
independently  of any information,  materials,  statements or opinions as to the
business,  affairs,  operations,  assets,  properties,  liabilities,  results of
operations, condition (financial or otherwise) or prospects of the Company or of
its Subsidiaries  which may have been made or given by any other Purchaser or by
any agent or employee of any other  Purchaser,  and no  Purchaser  or any of its
agents or  employees  shall have any  liability to any  Purchaser  (or any other
person) relating to or arising from any such information,  materials, statements
or opinions.  The Company  acknowledges that nothing contained herein, or in any
Transaction  Document,  and no action taken by any Purchaser  pursuant hereto or
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.  The Company  acknowledges  that 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. The Company
acknowledges   that  for  reasons  of   administrative   convenience  only,  the
Transaction  Documents  have been prepared by counsel for one of the  Purchasers
and such  counsel  does  not  represent  all of the  Purchasers  but  only  such
Purchaser and the other  Purchasers  have retained their own individual  counsel
with respect to the transactions  contemplated  hereby. The Company acknowledges
that  it 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 the Purchasers.
            (ff) DTC Status.  The Company's  transfer  agent is a participant in
and, as of the time of the  Closing,  the Common  Stock  shall be  eligible  for
transfer pursuant to the Depository Trust Company Automated  Securities Transfer
Program.  The name,  address,  telephone number, fax number,  contact person and
email address of the Company's  transfer agent is set forth on Schedule  2.1(ff)
hereto.
                                       12
            Section 2.2 Representations  and Warranties of the Purchasers.  Each
Purchaser  hereby makes the  following  representations  and  warranties  to the
Company  with  respect  solely  to  itself  and not with  respect  to any  other
Purchaser:
            (a) Organization and Standing of the Purchasers. If the Purchaser is
an entity,  such Purchaser is a corporation or partnership duly  incorporated or
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction of its incorporation or organization.
            (b)  Authorization and Power. Each Purchaser has the requisite power
and authority to enter into and perform this Agreement and the other Transaction
Documents,  as  applicable,  and to purchase the  Preferred  Shares and Warrants
being sold to it hereunder.  The  execution,  delivery and  performance  of this
Agreement  and the  Registration  Rights  Agreement  by such  Purchaser  and the
consummation by it of the transactions contemplated hereby and thereby have been
duly authorized by all necessary corporate or partnership action, and no further
consent  or   authorization  of  such  Purchaser  or  its  Board  of  Directors,
stockholders,  or  partners,  as the  case  may be,  is  required.  Each of this
Agreement  and the  Registration  Rights  Agreement  has been  duly  authorized,
executed and delivered by such Purchaser and  constitutes,  or shall  constitute
when  executed and  delivered,  a valid and binding  obligation of the Purchaser
enforceable against the Purchaser in accordance with the terms thereof.
            (c) No Conflicts.  The execution,  delivery and  performance of this
Agreement and the  Registration  Rights  Agreement and the  consummation by such
Purchaser of the transactions contemplated hereby and thereby or relating hereto
do not and  will not (i)  result  in a  violation  of such  Purchaser's  charter
documents or bylaws or other organizational  documents or (ii) conflict with, or
constitute  a default  (or an event  which with  notice or lapse of time or both
would  become a default)  under,  or give to others  any rights of  termination,
amendment,   acceleration  or  cancellation  of  any  agreement,   indenture  or
instrument  or  obligation  to which such  Purchaser  is a party or by which its
properties  or assets are bound,  or result in a violation of any law,  rule, or
regulation, or any order, judgment or decree of any court or governmental agency
applicable  to such  Purchaser  or its  properties  (except for such  conflicts,
defaults and violations as would not,  individually or in the aggregate,  have a
material  adverse effect on such  Purchaser).  Such Purchaser is not required to
obtain  any  consent,   authorization  or  order  of,  or  make  any  filing  or
registration with, any court or governmental  agency in order for it to execute,
deliver  or  perform  any  of  its  obligations  under  this  Agreement  or  the
Registration Rights Agreement or to purchase the Preferred Shares or acquire the
Warrants in accordance with the terms hereof,  provided that for purposes of the
representation  made in this  sentence,  such  Purchaser is assuming and relying
upon the accuracy of the relevant  representations and agreements of the Company
herein.
            (d)  Acquisition  for  Investment.  Each  Purchaser is acquiring the
Preferred  Shares and the Warrants solely for its own account for the purpose of
investment and not with a view to or for sale in connection  with  distribution.
Each Purchaser does not have a present intention to sell the Preferred Shares or
the  Warrants,  nor a present  arrangement  (whether or not legally  binding) or
intention to effect any  distribution of the Preferred Shares or the Warrants to
or  through  any  person  or  entity;  provided,  however,  that by  making  the
representations  herein and subject to Section 2.2(h) below, such Purchaser does
not agree to hold the Shares or the
                                       13
Warrants  for any  minimum  or other  specific  term and  reserves  the right to
dispose of the Shares or the Warrants at any time in accordance with Federal and
state   securities   laws  applicable  to  such   disposition.   Each  Purchaser
acknowledges  that it is able to bear the  financial  risks  associated  with an
investment in the  Preferred  Shares and the Warrants and that it has been given
full  access to such  records of the  Company  and the  subsidiaries  and to the
officers of the Company and the subsidiaries and received such information as it
has deemed  necessary or appropriate to conduct its due diligence  investigation
and has sufficient knowledge and experience in investing in companies similar to
the Company in terms of the Company's  stage of  development so as to be able to
evaluate the risks and merits of its investment in the Company.
            (e) Status of Purchasers. Each Purchaser is an "accredited investor"
as defined in Regulation D promulgated  under the Securities Act. Such Purchaser
is not required to be  registered  as a  broker-dealer  under  Section 15 of the
Exchange Act and such Purchaser is not a broker-dealer.
            (f)  Opportunities  for  Additional   Information.   Each  Purchaser
acknowledges that such Purchaser has had the opportunity to ask questions of and
receive  answers  from, or obtain  additional  information  from,  the executive
officers  of the  Company  concerning  the  financial  and other  affairs of the
Company,  and to the  extent  deemed  necessary  in  light  of such  Purchaser's
personal  knowledge of the  Company's  affairs,  such  Purchaser  has asked such
questions and received answers to the full  satisfaction of such Purchaser,  and
such Purchaser desires to invest in the Company.
            (g) No General  Solicitation.  Each Purchaser  acknowledges that the
Preferred Shares and the Warrants were not offered to such Purchaser by means of
any form of general or public solicitation or general  advertising,  or publicly
disseminated   advertisements   or   sales   literature,   including   (i)   any
advertisement,   article,   notice  or  other  communication  published  in  any
newspaper, magazine, or similar media, or broadcast over television or radio, or
(ii) any  seminar or meeting to which such  Purchaser  was invited by any of the
foregoing means of communications.
            (h) Rule 144.  Such  Purchaser  understands  that the Shares must be
held indefinitely  unless such Shares are registered under the Securities Act or
an exemption from  registration is available.  Such Purchaser  acknowledges that
such  Purchaser is familiar  with Rule 144 of the rules and  regulations  of the
Commission, as amended, promulgated pursuant to the Securities Act ("Rule 144"),
and that such person has been advised  that Rule 144 permits  resales only under
certain  circumstances.  Such Purchaser understands that to the extent that Rule
144 is not  available,  such Purchaser will be unable to sell any Shares without
either  registration  under  the  Securities  Act or the  existence  of  another
exemption from such registration requirement.
            (i) General.  Such Purchaser  understands  that the Shares are being
offered and sold in reliance on a transactional  exemption from the registration
requirement of Federal and state securities laws and the Company is relying upon
the  truth  and  accuracy  of  the  representations,   warranties,   agreements,
acknowledgments  and  understandings of such Purchaser set forth herein in order
to determine the  applicability  of such  exemptions and the suitability of such
Purchaser to acquire the Shares.
                                       14
            (j)  Independent  Investment.  Except  as  may be  disclosed  in any
filings with the Commission by the Purchasers under Section 13 and/or Section 16
of the Exchange Act, no Purchaser has agreed to act with any other Purchaser for
the purpose of acquiring,  holding,  voting or disposing of the Shares purchased
hereunder  for  purposes  of Section  13(d)  under the  Exchange  Act,  and each
Purchaser is acting independently with respect to its investment in the Shares.
            (k) Trading  Activities.  Each Purchaser's  trading  activities with
respect to the Shares shall be in  compliance  with all  applicable  federal and
state  securities laws. No Purchaser nor any of its affiliates has an open short
position in the Common Stock,  each Purchaser agrees that it shall not, and that
it will cause its  affiliates  not to, engage in any short sales with respect to
the Common Stock. In making its investment decision,  no Purchaser has relied on
any forward looking statements provided to such Purchaser by the Company.
                                   ARTICLE III
                                    Covenants
      The  Company  covenants  with each of the  Purchasers  as  follows,  which
covenants are for the benefit of the  Purchasers and their  permitted  assignees
(as defined herein).
            Section 3.1  Securities  Compliance.  The Company  shall  notify the
Commission in accordance with their rules and  regulations,  of the transactions
contemplated by any of the Transaction Documents, including filing a Form D with
respect to the Preferred Shares, Warrants,  Conversion Shares and Warrant Shares
as required under  Regulation D and  applicable  "blue sky" laws, and shall take
all other  necessary  action and proceedings as may be required and permitted by
applicable  law, rule and  regulation,  for the legal and valid  issuance of the
Preferred Shares, the Warrants,  the Conversion Shares and the Warrant Shares to
the Purchasers or subsequent holders.
            Section 3.2 Registration and Listing. As of the time of the Closing,
the Company shall cause its Common Stock to be registered  under  Sections 12(b)
or 12(g) of the Exchange  Act, to comply in all respects  with its reporting and
filing  obligations  under the  Exchange  Act, to comply  with all  requirements
related to any registration  statement filed pursuant to this Agreement,  and to
not take any  action  or file any  document  (whether  or not  permitted  by the
Securities Act or the rules promulgated thereunder) to terminate or suspend such
registration  or to terminate or suspend its  reporting  and filing  obligations
under the Exchange Act or Securities Act, except as permitted  herein. As of the
time of the Closing,  the Company will take all action necessary for the listing
or trading of its Common  Stock on the OTC Bulletin  Board or other  exchange or
market on which the Common  Stock is trading  and shall  ensure  that its Common
Stock shall continue to be traded on the OTC Bulletin Board or other exchange of
market on which its  Common  Stock may be traded in the  future.  Subject to the
terms of the Transaction  Documents,  the Company further covenants that it will
take such further action as the Purchasers  may reasonably  request,  all to the
extent  required  from time to time to enable the  Purchasers to sell the Shares
without  registration  under the  Securities  Act within the  limitation  of the
exemptions  provided by Rule 144 promulgated  under the Securities
                                       15
Act.  Upon the  request of the  Purchasers,  the  Company  shall  deliver to the
Purchasers a written certification of a duly authorized officer as to whether it
has complied with such requirements.
            Section 3.3  Inspection  Rights.  The Company shall  permit,  during
normal business hours and upon reasonable  request and reasonable  notice,  each
Purchaser or any employees,  agents or representatives  thereof, so long as such
Purchaser shall be obligated hereunder to purchase the Preferred Shares or shall
beneficially own any Preferred  Shares, or shall own Conversion Shares which, in
the aggregate,  represent more than 1% of the total combined voting power of all
voting  securities then  outstanding,  for purposes  reasonably  related to such
Purchaser's  interests as a stockholder to examine and make reasonable copies of
and extracts from the records and books of account of, and visit and inspect the
properties,  assets,  operations and business of the Company and any subsidiary,
and to discuss  the  affairs,  finances  and  accounts  of the  Company  and any
subsidiary with any of its officers, consultants,  directors, and key employees,
provided,  however,  that the Company  shall not provide to or discuss with such
Purchaser  any  material  non-public  information,  unless  prior  thereto  such
Purchaser shall have executed a written agreement  regarding the confidentiality
and use of such information.
            Section 3.4  Compliance  with Laws.  The Company shall  comply,  and
cause each subsidiary to comply,  with all applicable laws,  rules,  regulations
and orders, noncompliance with which could have a Material Adverse Effect.
            Section 3.5  Keeping of Records  and Books of  Account.  The Company
shall keep and cause  each  subsidiary  to keep  adequate  records  and books of
account,  in  which  complete  entries  will  be made in  accordance  with  GAAP
consistently applied,  reflecting all financial  transactions of the Company and
its  subsidiaries,  and in which,  for each fiscal year, all proper reserves for
depreciation, depletion, obsolescence,  amortization, taxes, bad debts and other
purposes in connection with its business shall be made.
            Section 3.6 Reporting Requirements.  If the Commission ceases making
periodic  reports filed under the Exchange Act available via the Internet,  then
at a  Purchaser's  request  the Company  shall  furnish  the  following  to such
Purchaser so long as such Purchaser shall be obligated hereunder to purchase the
Preferred Shares or shall beneficially own any Shares:
            (a) Quarterly  Reports  filed with the  Commission on Form 10-QSB as
soon as practical  after the document is filed with the  Commission,  and in any
event within five (5) days after the document is filed with the Commission;
            (b) Annual  Reports filed with the Commission on Form 10-KSB as soon
as practical after the document is filed with the  Commission,  and in any event
within five (5) days after the  document is filed with the  Commission;  and
            (c)  Copies  of  all  notices  and  information,  including  without
limitation  notices and proxy  statements in connection with any meetings,  that
are provided to holders of shares of Common  Stock,  contemporaneously  with the
delivery of such notices or information to such holders of Common Stock.
                                       16
            Section 3.7  Amendments.  The  Company  shall not amend or waive any
provision  of the  Articles  or  Bylaws  of the  Company  in any way that  would
adversely  affect the  liquidation  preferences,  dividends  rights,  conversion
rights, voting rights or redemption rights of the Preferred Shares.
            Section 3.8 Other  Agreements.  The Company shall not enter into any
agreement  in which the terms of such  agreement  would  restrict  or impair the
right  or  ability  to  perform  of the  Company  or any  subsidiary  under  any
Transaction Document.
            Section 3.9 Distributions.  Excluding any items set forth in Section
3.11 hereto, so long as any Preferred Shares or Warrants remain outstanding, the
Company  agrees that it shall not (i) declare or pay any  dividends  or make any
distributions  to any  holder(s) of Common  Stock or (ii)  purchase or otherwise
acquire for value,  directly or  indirectly,  any Common  Stock or other  equity
security of the Company.
            Section 3.10 Status of Dividends.  The Company  covenants and agrees
that (i) no Federal  income tax return or claim for refund of Federal income tax
or other  submission  to the  Internal  Revenue  Service  (the  "Service")  will
adversely affect the Preferred Shares,  any other series of its Preferred Stock,
or  the  Common  Stock,  and  no  deduction  shall  operate  to  jeopardize  the
availability  to  Purchasers  of the dividends  received  deduction  provided by
Section 243(a)(1) of the Code or any successor  provision,  (ii) in no report to
shareholders or to any governmental body having jurisdiction over the Company or
otherwise will it treat the Preferred Shares other than as equity capital or the
dividends  paid thereon other than as dividends  paid on equity  capital  unless
required to do so by a governmental  body having  jurisdiction over the accounts
of the  Company  or by a change  in  generally  accepted  accounting  principles
required as a result of action by an authoritative  accounting standards setting
body,  and (iii) it will take no action which would result in the dividends paid
by the  Company  on  the  Preferred  Shares  out of  the  Company's  current  or
accumulated  earnings and profits being  ineligible  for the dividends  received
deduction  provided by Section  243(a)(1) of the Code.  The  preceding  sentence
shall not be deemed to prevent the Company from  designating the Preferred Stock
as  "Convertible   Preferred  Stock"  in  its  annual  and  quarterly  financial
statements  in accordance  with its prior  practice  concerning  other series of
preferred stock of the Company. In the event that the Purchasers have reasonable
cause to believe that dividends paid by the Company on the Preferred  Shares out
of the Company's current or accumulated earnings and profits will not be treated
as eligible for the dividends  received  deduction provided by Section 243(a)(1)
of the Code, or any  successor  provision,  the Company will, at the  reasonable
request of the Purchasers of 51% of the outstanding  Preferred Shares, join with
the  Purchasers in the  submission to the Service of a request for a ruling that
dividends  paid on the  Shares  will  be so  eligible  for  Federal  income  tax
purposes. In addition, the Company will reasonably cooperate with the Purchasers
in any  litigation,  appeal or other  proceeding  challenging  or contesting any
ruling, technical advice, finding or determination that earnings and profits are
not eligible for the dividends  received deduction provided by Section 243(a)(1)
of the Code,  or any  successor  provision to the extent that the position to be
taken in any such litigation, appeal, or other proceeding is not contrary to any
provision of the Code.  Notwithstanding the foregoing,  nothing herein contained
shall be deemed to preclude the Company from  claiming a deduction  with respect
to such dividends if (i) the Code shall hereafter be amended,  or final Treasury
regulations  thereunder are issued or
                                       17
modified, to provide that dividends on the Preferred Shares or Conversion Shares
should not be treated as  dividends  for Federal  income tax  purposes or that a
deduction  with  respect to all or a portion of the  dividends  on the Shares is
allowable  for Federal  income tax  purposes,  or (ii) in the absence of such an
amendment,  issuance or  modification  and after a  submission  of a request for
ruling or technical advice, the Service shall issue a published ruling or advise
that  dividends  on the Shares  should not be treated as  dividends  for Federal
income tax purposes.  If the Service specifically  determines that the Preferred
Shares or Conversion  Shares  constitute  debt, the Company may file  protective
claims for refund.
            Section 3.11 Use of Proceeds.  The net proceeds from the sale of the
Shares hereunder shall be used by the Company as set forth on Schedule 3.11.
            Section 3.12 Reservation of Shares.  So long as any of the Preferred
Shares or  Warrants  remain  outstanding,  the  Company  shall  take all  action
necessary  to at all times have  authorized,  and  reserved  for the  purpose of
issuance, no less than a number of shares of Common Stock equal to the number of
shares of Common Stock that are not  currently  issued or reserved for issuance;
provided,  however,  upon the Company filing the Charter Amendment,  the Company
shall take all action  necessary to at all times have  authorized,  and reserved
for the  purpose  of  issuance,  free of  preemptive  rights  and other  similar
contractual rights of stockholders,  a number of shares of Common Stock equal to
one  hundred  fifty  percent  (150%) of the number of shares of Common  Stock as
shall from time to time be  sufficient  to effect the  conversion  of all of the
Preferred Shares and exercise of the Warrants then outstanding.
            Section 3.13 Transfer  Agent  Instructions.  The Company shall issue
irrevocable  instructions  to its transfer  agent,  and any subsequent  transfer
agent,  to issue  certificates,  registered in the name of each Purchaser or its
respective nominee(s),  for the Conversion Shares and the Warrant Shares in such
amounts as  specified  from time to time by each  Purchaser  to the Company upon
conversion  of the  Preferred  Shares or exercise of the Warrants in the form of
Exhibit G attached hereto (the "Irrevocable Transfer Agent Instructions"). Prior
to  registration  of the  Conversion  Shares and the  Warrant  Shares  under the
Securities  Act,  all  such  certificates  shall  bear  the  restrictive  legend
specified  in  Section  5.1 of this  Agreement.  The  Company  warrants  that no
instruction other than the Irrevocable  Transfer Agent Instructions  referred to
in this Section 3.13 will be given by the Company to its transfer agent and that
the Shares shall  otherwise be freely  transferable  on the books and records of
the Company as and to the extent provided in this Agreement and the Registration
Rights  Agreement.  If a  Purchaser  provides  the  Company  with an  opinion of
counsel,  in a generally  acceptable  form,  to the effect  that a public  sale,
assignment  or  transfer of all or some of such  Purchaser's  Shares may be made
without   registration  under  the  Securities  Act  and  any  applicable  state
securities laws or the Purchaser provides the Company with reasonable assurances
that such  Shares  can be sold  pursuant  to Rule 144 and any  applicable  state
securities laws within the limitations of Rule 144, the Company shall permit the
transfer,  and, in the case of the  Conversion  Shares and the  Warrant  Shares,
promptly  instruct its transfer agent to issue one or more  certificates in such
name and in such  denominations  as specified by such  Purchaser and without any
restrictive  legend.  The  Company  acknowledges  that  a  breach  by it of  its
obligations  under  this  Section  3.13  will  cause  irreparable  harm  to  the
Purchasers by vitiating the intent and purpose of the  transaction  contemplated
hereby.  Accordingly,  the  Company  acknowledges  that the  remedy at law for a
breach of its
                                       18
obligations  under this Section 3.13 will be inadequate and agrees, in the event
of a breach  or  threatened  breach by the  Company  of the  provisions  of this
Section 3.13,  that the Purchasers  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.
            Section 3.14 Disposition of Assets.  So long as any Preferred Shares
remain outstanding,  neither the Company nor any Subsidiary shall sell, transfer
or otherwise dispose of substantially  all of its properties,  assets and rights
including,  without limitation,  its software and intellectual  property, to any
person except for sales to customers in the ordinary  course of business or with
the prior written  consent of the holders of a majority of the Preferred  Shares
then outstanding.
            Section 3.15  Disclosure of  Transaction.  The Company shall issue a
press release  describing  the material terms of the  transactions  contemplated
hereby (the "Press Release") as soon as practicable  after the Closing but in no
event later than 9:00 A.M.  Eastern Time on the first  Trading Day following the
Closing.  The Company  shall also file with the  Commission a Current  Report on
Form 8-K (the "Form 8-K")  describing  the  material  terms of the  transactions
contemplated  hereby (and  attaching  as exhibits  thereto this  Agreement,  the
Registration  Rights  Agreement,  the  Certificate of  Designation,  the Lock-Up
Agreement,  the form of each series of Warrant and the Press Release) as soon as
practicable  following  the  Closing  Date but in no event  more  than  four (4)
Trading Days following the Closing Date,  which Press Release and Form 8-K shall
be subject to prior review and comment by the  Purchasers.  "Trading  Day" means
any day  during  which  the OTC  Bulletin  Board (or  other  quotation  venue or
principal  exchange  on which  the  Common  Stock is  traded)  shall be open for
trading.
            Section  3.16  Disclosure  of  Material  Information.   The  Company
covenants  and agrees that neither it nor any other person  acting on its behalf
has  provided or will  provide any  Purchaser  or its agents or counsel with any
information  that  the  Company   believes   constitutes   material   non-public
information  (other than with respect to the  transactions  contemplated by this
Agreement),  unless prior thereto such  Purchaser  shall have executed a written
agreement regarding the confidentiality and use of such information. The Company
understands  and confirms that each Purchaser  shall be relying on the foregoing
representations  in effecting  transactions  in  securities  of the Company.  By
executing this Agreement, each Purchaser agrees to keep all information provided
by the Company  confidential  (the  "Confidential  Information") and to only use
such  information in connection with  evaluating a purchase of the Shares.  Each
Purchaser shall destroy or return all Confidential  Information  provided by the
Company upon Company's request.
            Section  3.17 Pledge of  Securities.  The Company  acknowledges  and
agrees that the Shares may be pledged by a Purchaser in  connection  with a bona
fide margin agreement or other loan or financing  arrangement that is secured by
the  Common  Stock.  The  pledge  of  Common  Stock  shall not be deemed to be a
transfer,  sale or  assignment of the Common Stock  hereunder,  and no Purchaser
effecting a pledge of Common Stock shall be required to provide the Company with
any notice  thereof or otherwise  make any  delivery to the Company  pursuant to
this Agreement or any other Transaction Document;  provided that a Purchaser and
its pledgee shall be required to comply with the  provisions of Article V hereof
in order to  effect a sale,
                                       19
transfer or  assignment  of Common  Stock to such  pledgee.  At the  Purchasers'
expense,  the Company hereby agrees to execute and deliver such documentation as
a pledgee of the Common Stock may reasonably request in connection with a pledge
of the Common Stock to such pledgee by a Purchaser.
            Section 3.18 Form SB-2 Eligibility.  The Company currently meets the
"registrant  eligibility"  requirements set forth in the general instructions to
Form SB-2 and the  Company  shall file all  reports  required to be filed by the
Company with the Commission in a timely manner.
            Section 3.19 Lock-Up Agreement.  The persons listed on Schedule 3.20
attached  hereto  shall be  subject  to the  terms and  provisions  of a lock-up
agreement  in  substantially   the  form  as  Exhibit  E  hereto  (the  "Lock-Up
Agreement"),  which shall  provide the manner in which such  persons  will sell,
transfer or dispose of their shares of Common Stock.
            Section 3.20 Investor  Relations Firm. The company will agree to set
aside a minimum of  $250,000  to be used  exclusively  for  investor  relations,
including but not limited to hiring an Investor Relations firm within 30 days of
closing.
            Section 3.21 Reverse Split of Outstanding Shares.  Immediately prior
to the consummation of the transactions  contemplated  hereby, the Company shall
effect a 4-to-1 reverse stock split  bringing  reducing its  outstanding  shares
from 5,584,000  shares of Common Stock to 1,396,000  shares of Common Stock (the
"Reverse Split").
            Section 3.22 Authorization of Preferred Shares. Immediately prior to
the consummation of the transactions contemplated hereby, the Company shall file
an amendment to the Articles with the Nevada Secretary of State to authorize the
issuance  of  the  Preferred  Shares  (the  "Preferred  Shares  Authorization"),
consistent  with the terms set forth in the  Certificate  of  Designation of the
Relative Rights and  Preferences of the Series A Convertible  Preferred Stock of
▇▇▇▇▇▇▇▇▇▇.▇▇▇ (the "Certificate of Designations") being executed by the Company
concurrent with the execution of this Agreement.
            Section 3.23  Increase in Authorized  Shares.  Not later than ninety
(90) days following the Closing Date, the Company shall file an amendment to the
Articles with the Nevada  Secretary of State to effect an increase in the number
of its  authorized  shares  of  Common  Stock to at least a number  of shares of
Common  Stock  sufficient  to reserve one hundred  fifty  percent  (150%) of the
number of shares of Common  Stock as shall  from time to time be  sufficient  to
effect  the  conversion  of all of the  Preferred  Shares  and  exercise  of the
Warrants  then  outstanding  (the  "Charter  Amendment").  In the event that the
Authorized  Share  Increase  has not  been  effected  within  ninety  (90)  days
following the Closing Date, the term of each series of Warrant  issued  pursuant
to this Agreement shall be  automatically  extended for a period of one (1) year
(and the Company shall promptly issue to each Purchaser new Warrants  evidencing
the extension of such Warrant term) and each  Purchaser  shall have the right to
redeem any Preferred  Shares then held by it in accordance with the terms of the
Certificate of Designation.
            Section 3.24 Subsequent Financings.
                                       20
            (a) For a period of one (1) year following the effective date of the
Registration  Statement (as defined in the Registration  Rights Agreement),  the
Company  covenants and agrees to promptly notify in writing (a "Rights  Notice")
the  Purchasers of the terms and conditions of any proposed offer or sale to, or
exchange with (or other type of distribution  to) any third party (a "Subsequent
Financing"),  of  Common  Stock or any debt or  equity  securities  convertible,
exercisable or exchangeable into Common Stock. The Rights Notice shall describe,
in reasonable detail, the proposed  Subsequent  Financing,  the proposed closing
date of the  Subsequent  Financing,  which  shall  be no  earlier  than ten (10)
Trading  Days  from the date of the  Rights  Notice,  and all of the  terms  and
conditions  thereof.  The Rights Notice shall  provide each  Purchaser an option
(the "Rights Option") during the ten (10) Trading Days following delivery of the
Rights Notice (the "Option Period") to inform the Company whether such Purchaser
will  purchase up to its pro rata portion of all or a portion of the  securities
being  offered in such  Subsequent  Financing  on the same,  absolute  terms and
conditions as contemplated by such Subsequent Financing. If any Purchaser elects
not to  participate  in such  Subsequent  Financing,  the other  Purchasers  may
participate on a pro-rata basis. For purposes of this Section, all references to
"pro rata" means,  for any Purchaser  electing to participate in such Subsequent
Financing,  the  percentage  obtained  by dividing  (x) the number of  Preferred
Shares purchased by such Purchaser at the Closing by (y) the total number of all
of the Preferred Shares purchased by all of the participating  Purchasers at the
Closing. If the Company does not receive notice of exercise of the Rights Option
from any or all of Purchasers  within the Option Period,  the Company shall have
the right to close the Subsequent  Financing on or before the scheduled  closing
date set forth in the  Rights  Notice (or within  thirty  (30) days  thereafter)
without the participation of any or all of such Purchasers; provided that all of
the material  terms and conditions of the closing are the same as those provided
to  the  Purchasers  in  the  Rights  Notice.  If the  closing  of the  proposed
Subsequent  Financing does not occur on the scheduled  closing date set forth in
the Rights  Notice (or within thirty (30) days  thereafter),  any closing of the
contemplated  Subsequent  Financing or any other  Subsequent  Financing shall be
subject to all of the  provisions of this Section  3.23(a),  including,  without
limitation,  the delivery of a new Rights Notice. The provisions of this Section
3.23(a) shall not apply to issuances of securities in a Permitted Financing.
            (b) For  purposes  of this  Agreement,  a  Permitted  Financing  (as
defined  hereinafter)  shall  not  be  considered  a  Subsequent  Financing.   A
"Permitted  Financing" shall mean (i) securities issued (other than for cash) in
connection  with a merger,  acquisition,  or  consolidation,  or the issuance of
securities  in  connection  with the  purchase  of patent or  related  rights to
medical equipment or devices, (ii) warrants for up to 3,000,000 shares of Common
Stock of the  Company in  connection  with an  employee  stock  option  program,
incentive stock option program,  or other  qualified or  non-qualified  employee
benefit plan (an "ESOP") to be  established  concurrent  with the closing of the
Merger (as defined in Section 4.2(c)  hereof),  priced at $1.81 per share, to be
issued to the current management of Medpro Safety Products,  Inc. ("Medpro") and
the future  management  of the  Company  (the  "ESOP  Warrants"),  (iii)  68,036
warrants,  priced at $1.99,  to be issued to ▇▇▇▇▇▇▇▇  Research  (the  "▇▇▇▇▇▇▇▇
Research Warrants"),  (iv) 533,458 warrants, priced at $1.81, to be issued to SC
Capital Partners,  LLC (the "SC Capital  Warrants"),  (v) Common Stock issued or
the  issuance  or grants of options to  purchase  Common  Stock  pursuant to the
Company's  stock option plans and employee stock  purchase plans  outstanding as
they exist on the date of this  Agreement,  and (vi) any warrants  issued to the
                                       21
placement  agent,  any investor  relations  firm,  and their  designees  for the
transactions contemplated by the Purchase Agreement.
            (c) For a period of two (2) years  following the Closing  Date,  the
Company  shall be  prohibited  from  effecting or entering  into an agreement to
effect any Subsequent  Financing involving a "Variable Rate Transaction" without
the prior  written  consent of the holders of 75% of the  Preferred  Shares then
outstanding;  provided,  however,  that the  number  of  Preferred  Shares  then
outstanding is greater than two hundred thousand  (200,000).  The term "Variable
Rate Transaction"  shall mean a transaction in which the Company issues or sells
(i) any debt or equity  securities  that are convertible  into,  exchangeable or
exercisable  for,  or include the right to receive  additional  shares of Common
Stock either (A) at a conversion,  exercise or exchange rate or other price that
is based upon and/or  varies with the trading  prices of or  quotations  for the
shares of Common  Stock at any time after the  initial  issuance of such debt or
equity securities, or (B) with a conversion,  exercise or exchange price that is
subject to being reset at some  future  date after the initial  issuance of such
debt or equity security or upon the occurrence of specified or contingent events
directly or indirectly  related to the business of the Company or the market for
the Common Stock (other than  customary  anti-dilution  features) or (ii) enters
into any  agreement,  including,  but not  limited to, an equity line of credit,
whereby the Company may sell securities at a future determined price.
            (d) For the period  commencing on the Closing Date and ending on the
date that is one hundred  eighty (180) days  following the effective date of the
Registration  Statement,  the Company shall not file any registration  statement
under the  Securities Act without the prior written  consent of the  Purchasers,

securities or "blue sky" laws):
            THE  SECURITIES   REPRESENTED  BY  THIS  CERTIFICATE  (THE
            "SECURITIES")   HAVE  NOT  BEEN   REGISTERED   UNDER   THE
            SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES  ACT")
            OR  ANY  STATE  SECURITIES  LAWS  AND  MAY  NOT  BE  SOLD,
            TRANSFERRED  OR  OTHERWISE  DISPOSED OF UNLESS  REGISTERED
            UNDER  THE  SECURITIES  ACT  AND  UNDER  APPLICABLE  STATE
            SECURITIES LAWS OR  ▇▇▇▇▇▇▇▇▇▇.▇▇▇  SHALL HAVE RECEIVED AN
            OPINION OF COUNSEL THAT  REGISTRATION  OF SUCH  SECURITIES
            UNDER  THE  SECURITIES  ACT AND UNDER  THE  PROVISIONS  OF
            APPLICABLE STATE SECURITIES LAWS IS NOT REQUIRED.
            The Company agrees to reissue  certificates  representing any of the
Conversion Shares and the Warrant Shares,  without the legend set forth above if
at such time, prior to making any transfer of any such  securities,  such holder
thereof shall give written notice to the Company describing the manner and terms
of such  transfer  and  removal as the  Company  may  reasonably  request.  Such
proposed  transfer  and removal will not be effected  until:  (a) either (i) the
                                       25
Company  has  received  an  opinion of counsel  reasonably  satisfactory  to the
Company,  to the effect that the  registration  of the Conversion  Shares or the
Warrant Shares under the Securities Act or any applicable  state securities laws
is not required in connection with such proposed  transfer,  (ii) a registration
statement  under the Securities Act covering such proposed  disposition has been
filed by the Company  with the  Commission  and has become  effective  under the
Securities  Act,  (iii) the  Company  has  received  other  evidence  reasonably
satisfactory to the Company that such registration and  qualification  under the
Securities Act and state  securities  laws are not required,  or (iv) the holder
provides the Company with  reasonable  assurances that such security can be sold
pursuant to Rule 144 under the  Securities  Act and  pursuant to any  applicable
state securities laws; and (b) either (i) the Company has received an opinion of
counsel reasonably  satisfactory to the Company, to the effect that registration
or  qualification  under the  securities  or "blue sky" laws of any state is not
required in connection with such proposed  disposition,  or (ii) compliance with
applicable  state  securities  or "blue sky" laws has been  effected  or a valid
exemption  exists with  respect  thereto.  The Company  will respond to any such
notice from a holder within five (5) business  days. In the case of any proposed
transfer  under this Section 5.1,  the Company  will use  reasonable  efforts to
comply with any such applicable  state  securities or "blue sky" laws, but shall
in no event be required,  (x) to qualify to do business in any state where it is
not then  qualified,  (y) to take any action that would  subject it to tax or to
the general service of process in any state where it is not then subject, or (z)
to  comply  with  state  securities  or "blue  sky"  laws of any state for which
registration by coordination is unavailable to the Company.  The restrictions on
transfer  contained  in this Section 5.1 shall be in addition to, and not by way
of  limitation  of, any other  restrictions  on transfer  contained in any other
section of this Agreement.  Whenever a certificate  representing  the Conversion
Shares or  Warrant  Shares is  required  to be issued to a  Purchaser  without a
legend, in lieu of delivering physical certificates  representing the Conversion
Shares or Warrant  Shares  (provided  that a  registration  statement  under the
Securities  Act  providing for the resale of the Warrant  Shares and  Conversion
Shares  is then in  effect),  the  Company  shall  cause its  transfer  agent to
electronically  transmit the Conversion  Shares or Warrant Shares to a Purchaser
by crediting the account of such Purchaser or such Purchaser's Prime Broker with
the  Depository  Trust  Company  ("DTC")  through its Deposit  Withdrawal  Agent
Commission  ("DWAC") system (to the extent not inconsistent  with any provisions
of this Agreement).
                                   ARTICLE VI
                                 Indemnification
            Section 6.1 General  Indemnity.  The Company agrees to indemnify and
hold  harmless  the  Purchasers  (and  their  respective  directors,   officers,
managers, partners, members,  shareholders,  affiliates,  agents, successors and
assigns) from and against any and all losses, liabilities,  deficiencies, costs,
damages and expenses (including, without limitation, reasonable attorneys' fees,
charges  and  disbursements)  incurred  by the  Purchasers  as a  result  of any
inaccuracy in or breach of the representations,  warranties or covenants made by
the Company herein. Each Purchaser severally but not jointly agrees to indemnify
and hold harmless the Company and its directors,  officers,  affiliates, agents,
successors  and  assigns  from  and  against  any and all  losses,  liabilities,
deficiencies,  costs,  damages  and  expenses  (including,  without  limitation,
reasonable attorneys' fees, charges and disbursements) incurred by the Company a
                                       26
result of any  inaccuracy  in or breach of the  representations,  warranties  or
covenants made by such Purchaser herein. The maximum aggregate liability of each
Purchaser  pursuant to its  indemnification  obligations  under this  Article VI
shall not  exceed  the  portion of the  Purchase  Price  paid by such  Purchaser
hereunder.
            Section  6.2  Indemnification   Procedure.  Any  party  entitled  to
indemnification under this Article VI (an "indemnified party") will give written
notice  to the  indemnifying  party of any  matters  giving  rise to a claim for
indemnification;   provided,   that  the  failure  of  any  party   entitled  to
indemnification  hereunder  to give notice as provided  herein shall not relieve
the  indemnifying  party of its obligations  under this Article VI except to the
extent that the  indemnifying  party is actually  prejudiced  by such failure to
give  notice.  In case any  action,  proceeding  or claim is brought  against an
indemnified party in respect of which  indemnification is sought hereunder,  the
indemnifying  party  shall be  entitled  to  participate  in and,  unless in the
reasonable  judgment of the indemnified  party a conflict of interest between it
and the indemnifying party may exist with respect of such action,  proceeding or
claim, to assume the defense thereof with counsel reasonably satisfactory to the
indemnified  party.  In  the  event  that  the  indemnifying  party  advises  an
indemnified  party  that  it  will  contest  such a  claim  for  indemnification
hereunder,  or fails,  within thirty (30) days of receipt of any indemnification
notice to notify, in writing,  such person of its election to defend,  settle or
compromise,  at its sole cost and expense,  any action,  proceeding or claim (or
discontinues its defense at any time after it commences such defense),  then the
indemnified party may, at its option,  defend, settle or otherwise compromise or
pay such action or claim. In any event,  unless and until the indemnifying party
elects in writing to assume  and does so assume the  defense of any such  claim,
proceeding or action, the indemnified  party's costs and expenses arising out of
the defense,  settlement or  compromise of any such action,  claim or proceeding
shall be losses subject to  indemnification  hereunder.  The  indemnified  party
shall  cooperate  fully  with  the  indemnifying  party in  connection  with any
negotiation or defense of any such action or claim by the indemnifying party and
shall furnish to the indemnifying party all information  reasonably available to
the indemnified  party which relates to such action or claim.  The  indemnifying
party shall keep the  indemnified  party  fully  apprised at all times as to the
status of the defense or any settlement  negotiations  with respect thereto.  If
the  indemnifying  party  elects to defend  any such  action or claim,  then the
indemnified  party shall be entitled to participate in such defense with counsel
of its choice at its sole cost and expense.  The indemnifying party shall not be
liable for any settlement of any action,  claim or proceeding  effected  without
its prior written  consent.  Notwithstanding  anything in this Article VI to the
contrary,  the  indemnifying  party shall not,  without the indemnified  party's
prior written consent, settle or compromise any claim or consent to entry of any
judgment  in  respect  thereof  which  imposes  any  future  obligation  on  the
indemnified party or which does not include,  as an unconditional  term thereof,
the  giving by the  claimant  or the  plaintiff  to the  indemnified  party of a
release  from all  liability  in  respect  of such  claim.  The  indemnification
required  by this  Article VI shall be made by  periodic  payments of the amount
thereof  during the course of  investigation  or defense,  as and when bills are
received or expense,  loss,  damage or  liability  is  incurred,  so long as the
indemnified party  irrevocably  agrees to refund such moneys if it is ultimately
determined by a court of competent jurisdiction that such party was not entitled
to  indemnification.  The  indemnity  agreements  contained  herein  shall be in
addition to (a) any cause of action or similar rights of the  indemnified  party
against
                                       27
the indemnifying party or others, and (b) any liabilities the indemnifying party
may be subject to pursuant to the law.
                                  ARTICLE VII
                                  Miscellaneous
            Section 7.1 Fees and Expenses. Except as otherwise set forth in this
Agreement and the other Transaction Documents, each party shall pay the fees and
expenses of its advisors,  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,  provided
that the Company shall pay all actual  attorneys'  fees and expenses  (including
disbursements  and  out-of-pocket   expenses)  incurred  by  the  Purchasers  in
connection with (i) the preparation, negotiation, execution and delivery of this
Agreement and the other Transaction Documents and the transactions  contemplated
thereunder,  which  payment  shall be made at the  Closing  and shall not exceed
$40,000 (plus  disbursements  and out-of-pocket  expenses),  (ii) the filing and
declaration of effectiveness by the Commission of the Registration Statement and
(iii) any amendments,  modifications  or waivers of this Agreement or any of the
other  Transaction  Documents.  The Company  shall also pay up to $30,000 to the
Purchasers at the Closing in connection  with all  reasonable and documented due
diligence  expenses  incurred  by the  Purchasers  and all  reasonable  fees and
expenses  incurred by the Purchasers in connection  with the enforcement of this
Agreement  or  any  of  the  other  Transaction  Documents,  including,  without
limitation, all reasonable attorneys' fees and expenses.
            Section 7.2 Specific Enforcement,  Consent to Jurisdiction.
            (a) The  Company  and the  Purchasers  acknowledge  and  agree  that
irreparable  damage would occur in the event that any of the  provisions of this
Agreement or the other  Transaction  Documents  were not performed in accordance
with their specific terms or were otherwise  breached.  It is accordingly agreed
that the parties shall be entitled to an injunction or injunctions to prevent or
cure breaches of the  provisions of this  Agreement or the  Registration  Rights
Agreement  and to  enforce  specifically  the  terms  and  provisions  hereof or
thereof,  this being in addition to any other remedy to which any of them may be
entitled by law or equity.
            (b) Each of the Company and the  Purchasers  (i) hereby  irrevocably
submits to the  jurisdiction  of the United States District Court sitting in the
Southern District of New York and the courts of the State of New York located in
New York county for the purposes of any suit,  action or proceeding  arising out
of or relating to this  Agreement or any of the other  Transaction  Documents or
the  transactions  contemplated  hereby or thereby and (ii) hereby  waives,  and
agrees not to assert in any such suit,  action or proceeding,  any claim that it
is not  personally  subject to the  jurisdiction  of such court,  that the suit,
action or  proceeding is brought in an  inconvenient  forum or that the venue of
the  suit,  action  or  proceeding  is  improper.  Each of the  Company  and the
Purchasers  consents  to  process  being  served  in any such  suit,  action  or
proceeding  by mailing a copy thereof 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 in this
Section 7.2 shall affect or limit any right to serve process in any other manner
permitted by law.
                                       28
            Section 7.3 Entire  Agreement;  Amendment.  This  Agreement  and the
Transaction  Documents  contains the entire  understanding  and agreement of the
parties with respect to the matters  covered hereby and,  except as specifically
set forth herein or in the Transaction Documents, neither the Company nor any of
the Purchasers makes any representations, warranty, covenant or undertaking with
respect  to such  matters  and  they  supersede  all  prior  understandings  and
agreements with respect to said subject matter,  all of which are merged herein.
No provision of this  Agreement may be waived or amended other than by a written
instrument  signed  by the  Company  and the  holders  of at least  seventy-five
percent (75%) of the Preferred Shares then outstanding;  provided, however, that
the number of  Preferred  Shares then  outstanding  is greater  than two hundred
thousand  (200,000),  and no  provision  hereof may be waived other than by an a
written  instrument  signed by the party  against whom  enforcement  of any such
amendment  or waiver is sought.  No such  amendment  shall be  effective  to the
extent that it applies to less than all of the holders of the  Preferred  Shares
then  outstanding.  No  consideration  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 or holders of Preferred Shares, as the
case may be.
            Section 7.4 Notices. Any notice,  demand,  request,  waiver or other
communication  required or permitted to be given  hereunder  shall be in writing

            Section 7.5  Waivers.  No waiver by either party 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  other

this  Agreement for any other purpose and shall not be deemed to limit or affect

parties need not sign the same  counterpart.  In the event that any signature is
delivered  by  facsimile   transmission  or  scanned  electronic  mail  (e-mail)

competent jurisdiction shall determine that any one or more of the provisions or
part of the provisions contained in this Agreement or the Transaction  Documents
shall,  for any reason,  be held to be invalid,  illegal or unenforceable in any
respect,  such invalidity,  illegality or unenforceability  shall not affect any
other  provision  or part of a provision of this  Agreement  or the  Transaction
Documents and such provision  shall be reformed and construed as if such invalid
or illegal or unenforceable provision, or part of such provision, had never been
contained herein, so that such provisions would be valid,  legal and enforceable
to the maximum extent possible.
