         shareholders,   members,  managers,  directors,   officers,  employees,
         affiliates,  legal counsel,  agents or representatives  with respect to

         that the Securities are characterized as "restricted  securities" under
         the 1933 Act and Rule 144 promulgated  thereunder  inasmuch as they are
         being acquired from the Company in a transaction not involving a public
         offering,  and  that  under  the 1933  Act and  applicable  regulations
         thereunder such securities may be resold without registration under the
         1933 Act only in certain  limited  circumstances.  In this  connection,
         such  Subscriber  represents that such Subscriber is familiar with Rule
         144 of the 1933 Act, as presently in effect, and understands the resale
         limitations  imposed  thereby  and by the  1933  Act.  Such  Subscriber
         understands  that the Company is under no obligation to register any of
         the  securities  sold  hereunder  except  as may be  described  in this

                  experience in financial and business matters, in general,  and
                  in  investments  similar to an investment  in the Company,  in
                  particular,  that the  Subscriber is capable of evaluating the
                  merits  and risks of an  investment  in the  Shares  described
                  herein;  and the Subscriber has obtained,  in the Subscriber's
                  discretion,   sufficient   information  from  the  Company  to
                  evaluate the merits and risks of such investment;

                  indefinite period of time, including the risk of losing all of
                  the Subscriber's investment; and

                           2.1.8.3 by reason of the  Subscriber's  knowledge and
                  experience in business and financial  matters,  the Subscriber
                  has  acquired  the  capacity  to protect  its own  interest in
                  investments  of this nature and is capable of  evaluating  the
                  risks, merits and other facets of this investment.

         exercise of the  Company's  discretion  in those  matters is within the
         sole discretion of its management and its Board of Directors.

         (i) violate (1) any provision of law applicable to the Company,  except
         that  no  representation  or  warranty  is  made  with  respect  to any
         so-called   "blue  sky  laws"  of  any  state,   (2)  its  articles  of
         incorporation  or other  organizational  documents,  (3) any applicable

         assets or property  is bound,  (ii) be in  conflict  with,  result in a
         breach of or  constitute  (with due  notice or lapse of time or both) a
         default  under any  indenture,  agreement or other  instrument or (iii)
         result in the creation or imposition of any lien, charge or encumbrance
         of any nature  whatsoever  upon any of its  property  or  assets.  This
         Agreement is a valid and binding obligation of the Company  enforceable
         against it in accordance with its terms except as limited by applicable
         bankruptcy,  insolvency,  reorganization,  moratorium  or other laws of
         general application relating to or affecting  enforcement of creditors'
         rights and rules or laws concerning equitable remedies.

                 2.2.4 Changes.  Since the date of the last filing with the SEC,
         to the best knowledge of the Company,  after reasonable inquiry,  there
         has not been any (i)  material  adverse  change in the  business of the
         Company,  and (ii) there have been no transactions  entered into by the
         Company or any of its  subsidiaries,  other than those in the  ordinary
         course of business,  which are material  with respect to the  business,
         taken as a whole.

                 2.2.5 Valid Issuance.  The Shares,  when delivered  pursuant to
         this  Agreement  against  receipt  of  the  Subscription  Price  by the
         Company,  as provided  herein,  shall be validly  issued and fully paid
         Shares of the Company,  and will be free of any liens and  encumbrances
         other than as a result of any actions by the  Subscriber.  The issuance
         of the Shares is not  subject to  preemptive  or other  similar  rights
         which have not been waived.

                  2.2.6    "Piggyback" Registration.

                           2.2.6.1  Basic  Right.  At any time during the period
                  commencing  on the  issuance  date of the  Shares  under  this
                  Agreement  ("Issue Date") and ending two years after the Issue
                  Date,  the  Company  proposes  to  register  any of its equity
                  securities under the Securities Act, other than in an offering
                  on Form S-8 or Form  S-4 or any  successor  form,  it shall at
                  least  10  days  prior  to the  filing  of  such  registration

                  "Commission")  give  notice  of  its  intention  to  do  so to
                  Subscriber.  If Subscriber  notifies the Company within 5 days
                  of the date of the  Company  notice of  filing a  registration
                  statement of Subscriber's desire to include any Shares in such
                  proposed registration statement, the Company shall, subject to
                  the provisions of 2.2.6.2 below, include the Shares designated
                  by Subscriber in such registration statement. Anything in this
                  subparagraph  2.2.6.1  to the  contrary  notwithstanding,  the
                  "piggyback"  registration  rights  described  herein  shall be
                  available for exercise by Subscriber on one occasion only and,
                  after the exercise  thereof in accordance  with the provisions
                  set  forth  herein,  the  Company  shall be  under no  further
                  obligation  to give  Subscriber  the notice  described in this
                  subparagraph  2.2.6.1  to  include  any of the  Shares  in any
                  subsequent registration statement.  The Company hereby informs
                  Subscriber  that  it has a  present  intention  to file an S-1
                  Registration  within 45 days after acceptance hereof and shall
                  use its best efforts to cause such  registration  statement to
                  become effective as soon as possible.

                           all action  necessary to  facilitate  the sale by the
                           Subscriber of the Shares, including furnishing to the
                           Subscriber  such  number of  prospectuses  reasonably
                           required by the  Subscriber to dispose of its Shares,
                           using its best  efforts to  register  or qualify  the
                           Shares  under  the 1933 Act and  applicable  blue sky
                           laws and delivering underwriting agreements and other
                           documents   customarily   delivered   by  issuers  in
                           connection with public offerings.

                                    (b) With respect to the  inclusion of Shares
                           in a registration statement pursuant to this Section,
                           all fees,  costs and  expenses of and  incidental  to
                           such  inclusion   shall  be  borne  by  the  Company;
                           provided, however, that the Subscriber shall bear any
                           fees and  disbursements  of counsel  retained  by the
                           Subscriber  (other than counsel also  retained by the
                           Company).

                                    (c) The  Subscriber  shall be entitled  to
                           customary  indemnification and rights of contribution
                           relating to the registration of the Shares.

                           2.2.6.2   Withdrawal   of   Registration   Statement.
                  Notwithstanding the provisions of subparagraph  2.2.6.1 above,
                  the  Company  shall at all times  have the  absolute  right to
                  elect not to file any proposed registration  statement,  or to
                  withdraw the same after the filing but prior to the  effective
                  date thereof.  In addition,  notwithstanding the provisions of
                  subparagraph  2.2.6.1 above, the Company may exclude from such
                  registration  statement  all or a portion  of the  Shares  for
                  which  registration  was  requested by  Subscriber  if, in the
                  written opinion of the Company's managing  underwriter for any
                  securities  being sold by the  Company and  registered  on the
                  same  registration  statement  as  the  Shares,  if  any,  the
                  inclusion  of all or a portion of such  Shares,  when added to
                  the securities being registered for sale by the Company,  will
