         SECTION  3.  REPRESENTATIONS  AND  WARRANTIES  OF THE  INVESTOR  TO THE
                      COMPANY.

         The Investor  represents and warrants to the Company, as of the date of
this Agreement and as of the Closing date, as follows:

         (a) The  execution,  delivery and  performance  by the Investor of this
Agreement and issuance of the Purchased  Shares have been duly authorized by all
requisite  action  on the part of the  Investor.  This  Agreement  has been duly

         agreement, document, instrument, contract, understanding,  arrangement,

                                      -2-
<PAGE>

         or under which the  Investor or any of its assets are bound or affected
         or conflict with any  organizational or other governing document of the
         Investor; or

                  (iii) result in the creation of any lien,  security  interest,
         charge  or  encumbrance  upon any of the  properties  or  assets of the
         Investor.

         (b) The Investor  understands  and  acknowledges  that the offering and
sale of the Purchased Shares pursuant to this Agreement is intended to be exempt
from  registration  under the Securities Act, and from  qualification  under any
applicable  state securities law by virtue of Section 4(2) of the Securities Act
and Rule 506 of Regulation D thereunder,  on the ground,  among others,  that no
distribution  or public  offering of Purchased  Shares is to be effected and the
Purchased  Shares will be issued by the Company in connection with a transaction
that does not involve any public  offering within the meaning of Section 4(2) of
the Securities  Act, the rules and  regulations of the United States  Securities
and Exchange Commission  thereunder,  or any comparable  provision of applicable
securities  laws or the  rules and  regulations  of the  regulatory  authorities
thereunder.

         (c) The Investor will acquire the Purchased  Shares for  investment for
the account of the Investor and not for the account of any other person, and not
with  a  view  toward  resale  or  other  distribution   thereof.  The  Investor
understands  that  the  Purchased  Shares  have not been  registered  under  the
Securities  Act  and  applicable   United  States  state  securities  laws  and,
therefore,  cannot be resold unless they are  subsequently  registered under the
Securities Act and applicable  United States state  securities laws or unless an
exemption from such registration is available.  The Investor further understands
and agrees that,  until so registered or transferred  pursuant to the provisions
of Rule 144 under the  Securities  Act,  the  certificate(s)  for the  Purchased
Shares  shall bear a legend,  prominently  stamped or printed  thereon,  reading
substantially as follows:

         THESE   SECURITIES  HAVE  NOT  BEEN   REGISTERED   UNDER  THE
         SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), OR
         APPLICABLE  STATE SECURITIES LAWS. THESE SECURITIES HAVE BEEN
         ACQUIRED  FOR  INVESTMENT  AND  NOT  WITH  A  VIEW  TO  THEIR
         DISTRIBUTION  OR  RESALE,  AND MAY NOT BE SOLD,  PLEDGED,  OR
         OTHERWISE  TRANSFERRED  WITHOUT  AN  EFFECTIVE   REGISTRATION
         STATEMENT FOR SUCH  SECURITIES  UNDER THE  SECURITIES ACT AND
         APPLICABLE  STATE  SECURITIES  LAWS, OR AN OPINION OF COUNSEL
         SATISFACTORY   TO  THE   COMPANY  TO  THE  EFFECT  THAT  SUCH
         REGISTRATION IS NOT REQUIRED.

         The Investor  understands and agrees that it is the Company's intent to
take action to  authorize  all of the  Company's  issued  stock,  including  the
Purchased  Shares,  to be tradable on an open market.  Investor  understands and
agrees,  however, that such actions may not be successful and, that Rule 144 may
not be available as a basis for exemption from registration.

         (d) The Investor,  during the course of this  transaction  and prior to
the purchase of the Purchased  Shares,  has had the opportunity to ask questions
of and receive answers from  representatives of the Company concerning the terms
and  conditions of the offering,  and to obtain any  additional  information  or
documents  relative to the  Company,  its  business  and an  investment,  as the
Investor has deemed necessary.  The Investor agrees and  acknowledges,  however,
that it has not been furnished any offering literature or prospectus  concerning
the Company other than this Agreement and, in making its decision to acquire the
Purchased Shares  hereunder,  the Investor has relied solely upon this Agreement
and independent  investigations made by the Investor.  The Investor acknowledges
that no  representations  or  warranties  have been made to the  Investor by the
Company, or any officer,  employee, agent or affiliate of the Company, except as
contained in this Agreement.

         (e) The Investor  understands  that the  offering of  Purchased  Shares
pursuant to this Agreement is limited solely to "accredited  investors," as that
term is  defined  in  Regulation  D  under  the  Securities  Act.  The  Investor
represents  and  warrants to the  Company  that the  Investor is an  "accredited
investor", as so defined, by

                                      -3-
<PAGE>

virtue of the  Investor  meeting  the  criteria  checked by the  Investor on the
signature page hereto, and that the Investor's principal place of business is as
listed on the signature page hereto.

         (f) The  Investor  has the  capacity  to protect its own  interests  in
connection  with the  purchase  of the  Purchased  Shares.  The  purchase of the
Purchased  Shares by the  Investor is  consistent  with its  general  investment
objectives  and the  Investor  understands  that the  purchase of the  Purchased
Shares is a  speculative  investment  that  involves a high degree of risk.  The
Investor  can  bear  the  economic  risks of this  investment  and can  afford a
complete  loss  of  its  investment  in  the  Purchased  Shares.   The  Investor
understands that there is no established  market for the Company's capital stock
(including, without limitation, Common Stock) and there is no assurance that any
public market for such stock will develop.  The Investor has no present need for
liquidity in connection with its purchase of the Purchased Shares.

         (g) The Investor understands and acknowledges that the Purchased Shares
are  "restricted  securities"  under  United  States  securities  laws  and  any
purported  transfer of the Purchased  Shares in violation of  applicable  law is
null and void. The Investor  understands and acknowledges  that the Company may,
at its discretion,  refuse to register on its share transfer books any purported
transferee of the Purchased Shares in the event of an attempted transfer thereof
in violation of applicable law.

         SECTION 4.  INDEMNIFICATION.  The Investor agrees to indemnify and hold
harmless  the  Company  and its  affiliates  from and  against any and all loss,
liability,  claim, damage and expense whatsoever (including, but not limited to,
any  and  all  expenses  reasonably  incurred  in  investigating,  preparing  or
defending   against  any  litigation   commenced  or  threatened  or  any  claim
whatsoever)  arising  out of or based  upon:  (a) any false  representation  and
warranty of the Investor contained in this Agreement or any breach or failure by
the Investor to comply with any covenant  and/or  agreement made by the Investor
herein;   or  (b)  any  transfer  of  the  Purchased  Shares  contrary  to  such
representations and warranties or covenants and agreements.

         SECTION 5. TERMINATION.  Either party may terminate this Agreement upon
material  breach of this Agreement by the other party that has not been cured in
its entirety within five (5) business days after written notice thereof has been
provided to the breaching  party.  The parties  agree that a party's  failure to
consummate the Installment  Closings in accordance with the terms and conditions
of this Agreement constitute a material breach by such party of this Agreement.

         SECTION 6.  GENERAL PROVISIONS.

         (a)  REMEDIES.  In  case  any  one  or  more  of the  covenants  and/or
agreements  set forth in this  Agreement  shall have been  breached by any party
hereto,  the party  entitled to the benefit of such  covenants or agreements may
proceed to protect  and enforce  their  rights  either by suit in equity  and/or
action at law, including,  but not limited to, an action for damages as a result
of any such  breach  and/or  an  action  for  specific  performance  of any such
covenant or  agreement  contained  in this  Agreement.  The  rights,  powers and
remedies of the parties under this Agreement are cumulative and not exclusive of
any other  right,  power or remedy  which such  parties may have under any other
agreement or law. No single or partial assertion or exercise of any right, power
or remedy of a party hereunder shall preclude any other or further  assertion or
exercise thereof.

         (b)  SUCCESSORS  AND ASSIGNS.  Except as otherwise  expressly  provided
herein,  this  Agreement  shall bind and inure to the benefit of the Company and
the  Investor  and their  respective  permitted  successors  and  assigns.  This
Agreement may not be assigned by either party without the prior written  consent
of the other party.

         (c) ENTIRE  AGREEMENT.  This  Agreement  (including  any  schedules and
exhibits hereto) contains the entire agreement among the parties with respect to
the  subject  matter  hereof  and  supersedes  all  prior  and   contemporaneous
arrangements or understandings, whether written or oral, with respect thereto.

modified or amended,  or any of the  provisions  hereof  waived,  temporarily or
permanently,   except  pursuant  to  a  writing   executed  by  duly  authorized
representatives of the Company and the Investor.

         (e)  COUNTERPARTS.  This  Agreement  may be  executed  in any number of
counterparts  and by the  different  parties on  separate  counterparts  each of
which,  when so executed  and  delivered,  shall be an original but all of which
together shall constitute one and the same instrument.

         (f) SEVERABILITY. Any provision of this Agreement that is prohibited or
unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective
to the extent of such prohibition or unenforceability  without  invalidating the
remaining provisions hereof, and any such prohibition or unenforceability in any
jurisdiction shall not invalidate or render  unenforceable such provision in any
other jurisdiction.

         (g) GOVERNING LAW; VENUE; JURISDICTION.  The corporate law of the State
of Nevada  will  govern all  questions  concerning  the  relative  rights of the
Company and the holders of its securities  (including,  without limitation,  the
Purchased Shares). All other questions concerning the construction, validity and
interpretation of this Agreement will be governed by and construed in accordance
with the internal  laws of the State of Maryland,  without  giving effect to any
choice of law or  conflict  of law  provision  or rule  (whether of the State of
Maryland or any other jurisdiction) that would cause the application of the laws
of any  jurisdiction  other than the State of  Maryland.  The parties each agree
that venue for any dispute  arising under this Agreement  shall be proper in any
state  court  located in  Montgomery  County in the State of  Maryland or in the
United  States  District  Court for the  District  of  Maryland  (if a basis for
federal  jurisdiction exists) and each party hereby irrevocably waives any right
to object to the  maintenance  of a suit in such courts on the basis of improper
venue or of  inconvenience  of forum.  Each party  irrevocably  consents  to the
non-exclusive  jurisdiction  of any state court located in Montgomery  County in
the State of Maryland or in the United States District Court for the District of
Maryland (if a basis for federal jurisdiction exists).

         (h) WAIVER OF JURY  TRIAL.  The parties to this  Agreement  each hereby
irrevocably  waives,  to the fullest extent permitted by law, any right to trial
by jury of any  claim,  demand,  action or cause of action  arising  under  this
Agreement,  whether now existing or hereafter arising,  and whether in contract,
tort,  equity,  or  otherwise.   The  parties  to  this  Agreement  each  hereby
irrevocably agrees and consents that any such claim, demand,  action or cause of
action  shall be decided by court  trial  without a jury and that the parties to
this Agreement may file an original counterpart of a copy of this Agreement with
any court as written evidence of the consent of the parties hereto to the waiver
of their right to trial by jury.
