                         REPRESENTATIONS AND WARRANTIES

         2.1.   Representations  and  Warranties  of the  Company.  The  Company
                -------------------------------------------------
hereby makes the following representations and warranties to the Purchasers:

                (a)   Organization   and   Qualification.   The   Company  is  a
                      ----------------------------------
corporation duly  incorporated,  validly existing and in good standing under the
laws of the State of Utah with the  requisite  corporate  power and authority to
own and use its  properties and assets and to carry on its business as currently
conducted.  The Company has no subsidiaries  other than as set forth in Schedule
                                                                        --------
2.1(a) (collectively the "Subsidiaries"). Each of the Subsidiaries is an entity,
- ------
duly incorporated or otherwise organized,  validly existing and in good standing
under the laws of the  jurisdiction of its  incorporation  or  organization  (as
applicable),  with  the  requisite  power  and  authority  to own  and  use  its
properties and assets and to carry on its business as currently conducted.  Each
of the Company and the  Subsidiaries  is duly qualified to do business and is in
good standing as a foreign  corporation or other entity in each  jurisdiction in
which the nature of the business  conducted  or property  owned by it makes such
qualification necessary,  except where the failure to be so qualified or in good
standing, as the case may be, could not,  individually or in the aggregate,  (x)
adversely affect the legality,  validity or enforceability of the Securities (as
defined below) or any of this Agreement,  the Registration Rights Agreement, the
Security Agreement, the IP Security Agreement or the Transfer Agent Instructions
(collectively,  the "Transaction  Documents"),  (y) have or result in a material
adverse effect on the results of  operations,  assets,  prospects,  or condition
(financial or otherwise) of the Company and the Subsidiaries,  taken as a whole,
or (z) adversely impair the Company's ability to perform fully on a timely basis
its obligations under any of the Transaction  Documents (any of (x), (y) or (z),
a "Material Adverse Effect").



                                       3


                (b)   Authorization;  Enforcement. The Company has the requisite
                      ---------------------------
corporate  power and authority to enter into and to consummate the  transactions
contemplated by each of the Transaction Documents and otherwise to carry out its
obligations  thereunder.  The execution and delivery of each of the  Transaction
Documents  by  the  Company  and  the  consummation  by it of  the  transactions
contemplated  thereby have been duly  authorized by all necessary  action on the
part of the Company and no further  action is required by the  Company.  Each of
the  Transaction  Documents  has been duly  executed  by the Company  and,  when
delivered in accordance  with the terms hereof,  will  constitute  the valid and
binding obligation of the Company  enforceable against the Company in accordance
with its terms. Neither the Company nor any Subsidiary is in violation of any of
the  provisions  of its  respective  certificate  or articles of  incorporation,
by-laws or other organizational or charter documents.

                (c)   Capitalization.  The  number  of  authorized,  issued  and
                      --------------
outstanding  capital  stock of the Company is set forth in Schedule  2.1(c).  No
shares of Common Stock are entitled to preemptive or similar rights,  nor is any
holder of the securities of the Company entitled to preemptive or similar rights
arising out of any agreement or understanding  with the Company by virtue of any
of the Transaction Documents. Except as a result of the purchase and sale of the
Debentures and except as disclosed in Schedule 2.1(c),  there are no outstanding
                                      ---------------
options,  warrants,  script rights to subscribe to, calls or  commitments of any
character   whatsoever  relating  to,  or  securities,   rights  or  obligations
convertible  into or  exchangeable  for,  or  giving  any  Person  any  right to
subscribe for or acquire, any shares of Common Stock, or contracts, commitments,
understandings, or arrangements by which the Company or any Subsidiary is or may
become bound to issue additional shares of Common Stock, or securities or rights
convertible or exchangeable  into shares of Common Stock.  The issue and sale of
the Debentures or Underlying  Shares (as hereinafter  defined) will not obligate
the Company to issue  shares of Common Stock or other  securities  to any person
other  than the  Purchasers  (and  other than the  Initial  Investors  under the
Initial  Transaction)  and will not  result in a right of any  holder of Company
securities  to adjust the  exercise  or  conversion  or reset  price  under such
securities.

                (d)   Issuance of the  Debentures.  When issued,  the Debentures
                      ---------------------------
will be duly and validly issued,  free and clear of all liens,  encumbrances and
rights of first refusal of any kind (including rights of first refusal under the
Initial  Transaction  which are deemed satisfied with respect to this Agreement)
(collectively,  "Liens"). On the date hereof and on the Additional Funding Date,
the Company will have (and will, at all times while  Debentures are outstanding,
maintain)  an  adequate  reserve  of duly  authorized  shares of  Common  Stock,
reserved for issuance to the holders of such Debentures, to enable it to perform
its conversion and other obligations  under this Agreement,  and the Debentures.
Such number of reserved  and  available  shares of Common Stock is not less than
the sum of 210% of the number of shares of Common  Stock which would be issuable
upon conversion in full of the Debentures,  assuming such conversion occurred on
the Original Issue Date of the Debentures, the Debentures remain outstanding for
one year and all interest is paid in shares of Common Stock. All such authorized
shares of Common Stock shall be duly reserved for issuance to the holders of the
Debentures.  The  shares  of  Common  Stock  issuable  upon  conversion  of  the
Debentures are collectively  referred to herein as the "Underlying  Shares." The
Debentures and the Underlying Shares are collectively  referred to herein as the
"Securities."  When issued in accordance  with the  Debentures,  the  Underlying
Shares will be duly authorized,  validly issued,  fully paid and  nonassessable,
free and clear of all Liens.



                                       4


                (e)   No Conflicts.  The execution,  delivery and performance of
                      ------------
the Transaction  Documents by the Company and the consummation by the Company of
the transactions  contemplated thereby do not and will not: (i) conflict with or
violate any  provision  of the  Company's  or any  Subsidiary's  certificate  or
articles of  incorporation,  bylaws or other charter  documents (each as amended
through the date hereof),  or (ii) subject to obtaining  the Required  Approvals
(as defined  below),  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 (with
or without notice,  lapse of time or both) of, any agreement,  credit  facility,
debt or other instrument  (evidencing a Company or Subsidiary debt or otherwise)
or other  understanding  to which the Company or any Subsidiary is a party or by
which  any  property  or  asset of the  Company  or any  Subsidiary  is bound or
affected,  or (iii) result in a violation of any law, rule,  regulation,  order,
judgment,  injunction,  decree or other restriction of any court or governmental
authority to which the Company or a Subsidiary is subject (including federal and
state securities laws and regulations), or by which any property or asset of the
Company  or a  Subsidiary  is bound or  affected;  except in the case of each of
clauses (ii) and (iii), as could not, individually or in the aggregate,  have or
result in a Material  Adverse  Effect.  The business of the Company is not being
conducted in violation of any law,  ordinance or regulation of any  governmental
authority,  except for violations which, individually or in the aggregate, could
not have or result in a Material Adverse Effect.

                (f)   Filings,  Consents and Approvals.  Neither the Company nor
                      --------------------------------
any Subsidiary is required to obtain any consent, waiver, authorization or order
of, give any notice to, or make any filing or  registration  with,  any court or
other federal,  state, local or other governmental  authority or other Person in
connection  with the execution,  delivery and  performance by the Company of the
Transaction  Documents,  other than (i) the filings required pursuant to Section
3.10,  (ii)  the  filing  with  the  Securities  and  Exchange  Commission  (the
"Commission") of a registration  statement meeting the requirements set forth in

Shares by the Purchasers (the "Underlying Shares Registration Statement"), (iii)
applicable  Blue Sky  filings,  and (iv) in all other cases where the failure to
obtain such consent,  waiver,  authorization or order, or to give such notice or
make such filing or registration could not have or result in, individually or in
the  aggregate,   a  Material  Adverse  Effect   (collectively,   the  "Required
Approvals").

                (g)   Litigation;   Proceedings.   There  is  no  action,  suit,
                      -------------------------
inquiry,  notice of violation,  proceeding or  investigation  pending or, to the
knowledge of the Company,  threatened against or affecting the Company or any of
its Subsidiaries or any of their respective  properties  before or by any court,
arbitrator,  governmental  or  administrative  agency  or  regulatory  authority
(federal, state, county, local or foreign) (collectively, an "Action") which (i)
adversely affects or challenges the legality,  validity or enforceability of any
of the  Transaction  Documents or the Securities or (ii) could, if there were an
unfavorable  decision,  individually  or in the  aggregate,  have or result in a
Material  Adverse  Effect.  Neither  the  Company  nor any  Subsidiary,  nor any
director or officer thereof,  is or has been the subject of any Action involving
(A) a claim of violation of or liability under federal or state  securities laws
or (B) a claim of breach of  fiduciary  duty.  The Company does not have pending
before the Commission any request for confidential  treatment of information and
the Company has no  knowledge  of any  expected  such request that would be made
prior  to  the  Effectiveness  Date  (as  defined  in  the  Registration  Rights
Agreement)  and there has not been,  and to the best of the Company's  knowledge
there is not  pending  or  contemplated,  any  investigation  by the  Commission
involving  the  Company  or any  current  or former  director  or officer of the
Company.



                                       5


                (h)   No Default  or  Violation.  Neither  the  Company  nor any
                      -------------------------
Subsidiary:  (i) is in  default  under  or in  violation  of (and no  event  has
occurred which has not been waived which,  with notice or lapse of time or both,
would result in a default by the Company or any Subsidiary  under),  nor has the
Company or any Subsidiary received notice of a claim that it is in default under

Purchasers pursuant to the Security Agreement and Intellectual Property Security
Agreement will convey and grant to the Purchasers a priority  security  interest
in all of the  Collateral  (as such term is  defined in such  agreements)  which
security  interests shall be pari passu with the security interests created with
respect to the Initial Transaction.

                (i)   Private   Offering.   Assuming   the   accuracy   of   the
                      ------------------
representations   and  warranties  of  the  Purchasers  set  forth  in  Sections
2.2(b)-(f),  the offer, issuance and sale of the Securities to the Purchasers as

redeemed  (or made any  agreements  to  purchase  or  redeem)  any shares of its
capital stock.

                (l)   Investment  Company.  The  Company  is not,  and is not an
                      -------------------
Affiliate  of an  "investment  company"  within the  meaning  of the  Investment
Company Act of 1940, as amended.

                (m)   Certain  Fees. No fees or  commissions  will be payable by
                      -------------
the Company to any broker,  financial advisor or consultant,  finder,  placement
agent,  investment banker, bank or other Person with respect to the transactions
contemplated  by this  Agreement.  The Purchasers  shall have no obligation with
respect to any fees or with  respect to any claims made by or on behalf of other
Persons  for  fees of a type  contemplated  in this  Section  that may be due in
connection with the  transactions  contemplated  by this Agreement.  The Company
shall indemnify and hold harmless the  Purchasers,  their  employees,  officers,
directors,  agents,  and partners,  and their  respective  Affiliates,  from and
against all claims,  losses,  damages, costs (including the costs of preparation
and  attorney's  fees) and  expenses  suffered in respect of any such claimed or
existing fees, as such fees and expenses are incurred.

                (n)   Form S-B2 Eligibility. The Company is eligible to register
                      ---------------------
for resale under Form S-B2 promulgated under the Securities Act.


                (o)   Seniority. No indebtedness of the Company is senior to the
                      ---------
Debentures  in right of  payment,  whether  with  respect  to  interest  or upon
liquidation  or  dissolution,  or  otherwise  and all  debentures  issued to the
Initial Investors under the Initial  Transaction shall be ranked pari passu with
any Debentures issued hereunder.

                (p)   Listing and Maintenance Requirements Compliance. Except as
                      -----------------------------------------------
set forth in the SEC  Reports,  the Company has not, in the two years  preceding
the date  hereof,  received  notice  (written  or oral)  from  any  other  stock
exchange,  market or trading  facility on which the Common  Stock is or has been
listed (or on which it has been quoted) to the effect that the Company is not in
compliance with the listing or maintenance requirements of such exchange, market
or trading  facility.  The Company is, and has no reason to believe that it will
not in the  foreseeable  future  continue  to be,  in  compliance  with all such
listing and maintenance requirements.



                                       7


                (q)   Patents and Trademarks.  The Company and its  Subsidiaries
                      ----------------------
have,  or have rights to use,  all  patents,  patent  applications,  trademarks,
trademark  applications,  service marks, trade names,  copyrights,  licenses and
rights  which  are  necessary  or  material  for use in  connection  with  their
respective  businesses  as described in the SEC Reports and which the failure to
so have would have a Material Adverse Effect  (collectively,  the  "Intellectual
Property Rights"). Neither the Company nor any Subsidiary has received a written
notice  that  the  Intellectual  Property  Rights  used  by the  Company  or its
Subsidiaries  violates or infringes  upon the rights of any Person.  To the best
knowledge of the Company, all such Intellectual  Property Rights are enforceable
and  there  is no  existing  infringement  by  another  Person  of  any  of  the
Intellectual Property Rights.

                (r)   Registration  Rights;  Rights of Participation.  Except as
                      ----------------------------------------------
set forth on Schedule 6(b) to the Registration Rights Agreement, the Company has
             -------------
not granted or agreed to grant to any Person any rights (including  "piggy-back"
registration  rights) to have any securities of the Company  registered with the
Commission or any other  governmental  authority  which has not been  satisfied.
Except as set forth on Schedule 6(b) to the Registration  Rights  Agreement,  no
Person,   has  any  right  of  first  refusal,   preemptive   right,   right  of
participation,   or  any  similar  right  to  participate  in  the  transactions
contemplated by the Transaction Documents.

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

                (t)   Title.  The Company and the Subsidiaries do not have title
                      -----
to any real property.  Any real property and facilities  held under lease by the
Company  and its  Subsidiaries  are held by them  under  valid,  subsisting  and
enforceable  leases of which the Company and its  Subsidiaries are in compliance
and do not interfere  with the use made and proposed to be made of such property
and buildings by the Company and its Subsidiaries.

                (u)   Labor  Relations.  No material labor problem exists or, to
                      ----------------
the  knowledge of the Company,  is imminent with respect to any of the employees
of the Company.

                (v)   Disclosure.  The Company  confirms that neither it nor any
                      ----------
other  Person  acting on its behalf has provided  any of the  Purchasers  or its
agents or counsel with any  information  that  constitutes  or might  constitute
material non-public  information.  The Company understands and confirms that the
Purchasers  shall be  relying  on the  foregoing  representations  in  effecting
transactions  in  securities  of the  Company.  All  disclosure  provided to the
Purchasers regarding the Company, its business and the transactions contemplated
hereby, including the Schedules to this Agreement,  furnished by or on behalf of
the Company are true and  correct and do not contain any untrue  statement  of a
material fact or omit to state any material fact  necessary in order to make the
statements  made therein,  in light of the  circumstances  under which they were
made, not misleading.



                                       8


                (w)   Internal   Accounting   Controls.   The  Company  and  the
                      --------------------------------
Subsidiaries  maintain a system of internal  accounting  controls  sufficient to
provide  reasonable  assurance that: (i) transactions are executed in accordance
with  management's  general or specific  authorizations,  (ii)  transactions are
recorded  as  necessary  to  permit  preparation  of  financial   statements  in
conformity with generally accepted  accounting  principles and to maintain asset
accountability,  (iii) access to assets is  permitted  only in  accordance  with
management's   general  or  specific   authorization,   and  (iv)  the  recorded
accountability  for assets is compared  with the existing  assets at  reasonable
intervals and appropriate action is taken with respect to any differences.

                (x)   Solvency.  Based on the financial condition of the Company
                      --------
as of the Closing  Date:  (i) the Company's  fair  saleable  value of its assets
exceeds  the  amount  that will be  required  to be paid on or in respect of the
Company's  existing  debts and other  liabilities  (including  known  contingent
liabilities)  as they  mature;  (ii)  the  Company's  assets  do not  constitute
unreasonably  small capital to carry on its business for the current fiscal year
as now  conducted  and as proposed to be conducted  including  its capital needs
taking  into  account  the  particular  capital  requirements  of  the  business
conducted  by the  Company,  and  projected  capital  requirements  and  capital
availability  thereof; and (iii) the current cash flow of the Company,  together
with the proceeds the Company  would  receive,  were it to liquidate  all of its
assets,  after taking into account all  anticipated  uses of the cash,  would be
sufficient to pay all amounts on or in respect of its debt when such amounts are
required  to be paid.  The  Company  does not intend to incur  debts  beyond its
ability to pay such debts as they  mature  (taking  into  account the timing and
amounts of cash to be payable on or in respect of its debt).

                (y)   Application of Takeover  Protections.  The Company and its
                      ------------------------------------
Board of Directors have taken all necessary  action,  if any, in order to render
inapplicable any control share acquisition,  business  combination,  poison pill
(including  any  distribution  under a rights  agreement)  or other similar anti
takeover provision under the Company's  Certificate of Incorporation (or similar
charter  documents) or the laws of its state of  incorporation  that is or could
become  applicable  to the  Purchasers  as a result  of the  Purchasers  and the
Company  fulfilling  their  obligations  or  exercising  their  rights under the
Transaction  Documents,  including without  limitation the Company's issuance of
the Securities and the Purchasers' ownership of the Securities.



                                       9


         2.2.   Representations and Warranties of the Purchasers. Each Purchaser
                ------------------------------------------------
hereby for itself and for no other  Purchaser  represents  and  warrants  to the
Company as follows:

                (a)   Organization;  Authority. Such Purchaser is an entity duly
                      ------------------------
organized,  validly  existing  and  in  good  standing  under  the  laws  of the
jurisdiction  of its  organization  with the requisite  corporate or partnership
power  and  authority  to  enter  into  and  to  consummate   the   transactions
contemplated  by the  Transaction  Documents  and  otherwise  to  carry  out its
obligations  thereunder.  The  purchase  by  such  Purchaser  of the  Securities
hereunder has been duly  authorized by all necessary  action on the part of such
Purchaser.  Each of this  Agreement,  the  Registration  Rights  Agreement,  the
Security  Agreement and the Intellectual  Property  Security  Agreement has been
duly  executed  by such  Purchaser,  and when  delivered  by such  Purchaser  in
accordance with the terms hereof,  will constitute the valid and legally binding
obligation of such  Purchaser,  enforceable  against it in  accordance  with its
terms.

                (b)   Investment   Intent.   Such  Purchaser  is  acquiring  the
                      -------------------
Securities as principal for its own account for investment purposes only and not
with a view to or for  distributing  or reselling  such  Securities  or any part
thereof,  without prejudice,  however, to such Purchaser's right, subject to the
provisions of this Agreement and the Registration Rights Agreement, at all times
to sell or otherwise  dispose of all or any part of such Securities  pursuant to
an  effective  registration  statement  under  the  Securities  Act or  under an
exemption from such  registration and in compliance with applicable  federal and
state securities laws. Nothing contained herein shall be deemed a representation
or warranty by such Purchaser to hold  Securities  for any period of time.  Such
Purchaser is acquiring the  Securities  hereunder in the ordinary  course of its
business. Such Purchaser does not have any agreement or understanding,  directly
or indirectly, with any Person to distribute the Securities.

                (c)   Purchaser  Status.  At the time such Purchaser was offered
                      -----------------
the Securities, it was, and at the date hereof it is an "accredited investor" as
defined in Rule 501(a) under the  Securities  Act.  Such  Purchaser has not been
formed solely for the purpose of acquiring the Securities. Such Purchaser is not
a registered broker-dealer under Section 15 of the Exchange Act.

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

                (e)   Access to Information. Such Purchaser acknowledges that it
                      ---------------------
has reviewed the Disclosure Materials and has been afforded: (i) the opportunity
to ask such  questions  as it has deemed  necessary  of, and to receive  answers
from,  representatives of the Company concerning the terms and conditions of the
offering  of the  Securities  and the  merits  and  risks  of  investing  in the
Securities;  (ii) access to  information  about the  Company  and the  Company's
financial condition, results of operations, business, properties, management and
prospects  sufficient  to enable it to evaluate  its  investment;  and (iii) the
opportunity to obtain such additional information which the Company possesses or
can acquire without  unreasonable effort or expense that is necessary to make an
informed  investment  decision with respect to the  investment and to verify the
accuracy  and  completeness  of the  information  contained  in  the  Disclosure
Materials. Neither such inquiries nor any other investigation conducted by or on
behalf of such Purchaser or its  representatives or counsel shall modify,  amend
or affect such Purchaser's right to rely on the truth, accuracy and completeness
of the  Disclosure  Materials and the Company's  representations  and warranties
contained in the Transaction Documents.



                                       10


                (f)   General Solicitation. Such Purchaser is not purchasing the
                      --------------------
Securities as a result of or subsequent to any advertisement, article, notice or
other  communication  regarding  the  Securities  published  in  any  newspaper,
magazine or similar media or broadcast over  television or radio or presented at
any seminar or any other general solicitation or general advertisement.

                (g)   Reliance.  Such  Purchaser  understands  and  acknowledges
                      --------
that: (i) the  Securities are being offered and sold to it without  registration
under  the  Securities  Act in a  private  placement  that is  exempt  from  the
registration  provisions of the Securities Act and (ii) the availability of such
exemption,  depends in part on, and the Company  will rely upon the accuracy and
truthfulness  of,  the  foregoing  representations  and  such  Purchaser  hereby
consents to such reliance.

         The Company acknowledges and agrees that no Purchaser makes or has made
any representations or warranties with respect to the transactions  contemplated
hereby other than those specifically set forth in this Section 2.2.


                                  ARTICLE III

                         OTHER AGREEMENTS OF THE PARTIES

         3.1.   Transfer Restrictions.
                ---------------------

                (a)   Securities   may  only  be  disposed  of  pursuant  to  an
effective  registration  statement  under the Securities  Act, to the Company or
pursuant to an available  exemption from or in a transaction  not subject to the
registration  requirements  of the  Securities  Act, and in compliance  with any
applicable federal and state securities laws. In connection with any transfer of
Securities other than pursuant to an effective  registration statement or to the
Company,  except as  otherwise  set forth  herein,  the  Company may require the
transferor  thereof to provide to the Company an opinion of counsel  selected by
the  transferor,  the form and  substance of which  opinion  shall be reasonably
satisfactory  to the Company,  to the effect that such transfer does not require
registration of such  transferred  Securities under the Securities Act. Any such
transferee shall agree in writing to be bound by the terms of this Agreement and
shall have the rights of a Purchaser  under this Agreement and the  Registration
Rights Agreement.

                (b)   The  Purchasers  agree  to the  imprinting,  so long as is
required by this Section  3.1(b),  of the following  legend on the  certificates
evidencing the Securities:

                NEITHER THESE  SECURITIES  NOR THE  SECURITIES  INTO WHICH THESE
         SECURITIES ARE CONVERTIBLE HAVE BEEN REGISTERED WITH THE SECURITIES AND
         EXCHANGE  COMMISSION  OR THE  SECURITIES  COMMISSION  OF ANY  STATE  IN
         RELIANCE UPON AN EXEMPTION FROM  REGISTRATION  UNDER THE SECURITIES ACT
         OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND,  ACCORDINGLY,  MAY NOT
         BE  OFFERED  OR  SOLD  EXCEPT  PURSUANT  TO AN  EFFECTIVE  REGISTRATION
         STATEMENT  UNDER  THE  SECURITIES  ACT  OR  PURSUANT  TO  AN  AVAILABLE
         EXEMPTION  FROM, OR IN A TRANSACTION  NOT SUBJECT TO, THE  REGISTRATION
         REQUIREMENTS  OF THE SECURITIES ACT AND IN ACCORDANCE  WITH  APPLICABLE
         STATE SECURITIES LAWS AS EVIDENCED BY A LEGAL OPINION OF COUNSEL TO THE
         TRANSFEROR  TO SUCH EFFECT,  THE SUBSTANCE OF WHICH SHALL BE REASONABLY
         ACCEPTABLE TO THE COMPANY. THESE SECURITIES AND THE SECURITIES ISSUABLE
         UPON CONVERSION OF THESE SECURITIES MAY BE PLEDGED IN CONNECTION WITH A
         BONA FIDE MARGIN ACCOUNT OR OTHER LOAN SECURED BY SUCH SECURITIES.



                                       11


         The Company  acknowledges  and agrees that a Purchaser may from time to
time  pledge  pursuant  to a bona  fide  margin  agreement  or grant a  security
interest in some or all of the  Securities  and, if required  under the terms of
such arrangement,  such Purchaser may transfer pledged or secured  Securities to
the pledgees or secured parties.  Such a pledge or transfer would not be subject
to approval of the Company and no legal opinion of the pledgee, secured party or
pledgor shall be required in connection  therewith.  Further, no notice shall be
required of such pledge.  At the appropriate  Purchaser's  expense,  the Company
will execute and deliver such reasonable  documentation  as a pledgee or secured
party of  Securities  may  reasonably  request  in  connection  with a pledge or
transfer of the Securities  including the preparation and filing of any required
prospectus  supplement  under  Rule  424(b)(3)  of the  Securities  Act or other
applicable  provision of the Securities Act to  appropriately  amend the list of
selling stockholders thereunder.

         (c)    Certificates  evidencing Underlying Shares shall not contain the
legend set forth  above nor any other  legend if the  conversion  of  Debentures
occurs  at any  time  while  an  Underlying  Shares  Registration  Statement  is
effective  under  the  Securities  Act or the  holder  is  relying  on Rule  144
promulgated  under the Securities Act ("Rule 144") in connection with the resale
of such Underlying Shares, or in the event there is not an effective  Underlying
Shares Registration Statement,  and Rule 144 is not then available for resale of
the  Underlying  Shares,  at such  time as such  legend  is not  required  under
applicable    requirements   of   the   Securities   Act   (including   judicial
interpretations and pronouncements  issued by the staff of the Commission).  The
Company  shall  cause its  counsel to issue the legal  opinion  included  in the
Transfer Agent  Instructions to the Company's transfer agent on the date that an
Underlying Shares Registration Statement is declared effective by the Commission
(such date,  the  "Effective  Date").  The Company  agrees  that  following  the
Effective  Date,  it will,  no later than three (3) Trading Days  following  the
delivery  by a  Purchaser  to  the  Company  of a  certificate  or  certificates
representing Underlying Shares issued with a restrictive legend, deliver to such
Purchaser  certificates  representing such Underlying Shares which shall be free
from all restrictive and other legends. The Company may not make any notation on
its records or give  instructions  to any  transfer  agent of the Company  which
enlarge the restrictions of transfer set forth in this Section.

         3.2.   Performance of  Obligation.  The Company  acknowledges  that the
                --------------------------
issuance of Underlying  Shares upon  conversion of the Debentures will result in
dilution  of the  outstanding  shares of Common  Stock,  which  dilution  may be
substantial under certain market  conditions.  The Company further  acknowledges
that its obligation to issue Underlying  Shares upon conversion of the Debenture
is  unconditional  and  absolute,  subject to the  limitations  set forth in the
Debentures, regardless of the effect of any such dilution.



                                       12


         3.3.   Furnishing  of  Information.  As  long  as  the  Purchasers  own
                ---------------------------
Securities,  the  Company  covenants  to timely  file (or obtain  extensions  in
respect  thereof  and file  within the  applicable  grace  period)  all  reports
required  to be filed by the Company  after the date hereof  pursuant to Section
13(a) or 15(d) of the Exchange Act. As long as the Purchasers own Securities, if
the Company is not required to file reports  pursuant to such sections,  it will
prepare and furnish to the Purchasers and make publicly  available in accordance
with Rule 144(c)  promulgated  under the Securities  Act such  information as is
required for the  Purchasers to sell the Securities  under Rule 144  promulgated
under the Securities Act. The Company  further  covenants that it will take such
further action as any holder of Securities may  reasonably  request,  all to the
extent  required  from time to time to  enable  such  Person to sell  Underlying
Shares  without  registration  under the Securities Act within the limitation of
the  exemptions  provided  by Rule 144  promulgated  under the  Securities  Act,
including causing its attorneys to render and deliver any legal opinion required
in  order  to  permit a  Purchaser  to  receive  Underlying  Shares  free of all
restrictive  legends and to subsequently  sell Underlying  Shares under Rule 144
upon receipt of a notice of an intention to sell or other form of notice  having
a similar effect. Upon the request of any such Person, the Company shall deliver
to such  Person a  written  certification  of a duly  authorized  officer  as to
whether it has complied with such requirements.

         3.4.   Integration.  The  Company  shall  not,  and  shall use its best
                -----------
efforts to ensure that, no Affiliate of the Company shall,  sell, offer for sale
or solicit  offers to buy or otherwise  negotiate in respect of any security (as
defined in Section 2 of the  Securities  Act) that would be integrated  with the
offer or sale of the Securities in a manner that would require the  registration
under the Securities Act of the sale of the Securities to the Purchasers.

         3.5.   Increase in Authorized  Shares. If on any date the Company would
                ------------------------------
be, if a notice of conversion were to be delivered on such date,  precluded from
issuing 210% of the number of Underlying Shares as would then be issuable upon a
conversion in full of the Debentures (the "Current Required Minimum"), in either
case,  due to the  unavailability  of a  sufficient  number  of  authorized  but
unissued or reserved shares of Common Stock,  then the Board of Directors of the
Company shall promptly (and in any case, within 30 Business Days from such date)
prepare and mail to the  stockholders of the Company proxy materials  requesting
authorization to amend the Company's certificate or articles of incorporation to
increase the number of shares of Common Stock which the Company is authorized to
issue  to at  least  such  number  of  shares  as  reasonably  requested  by the
Purchasers in order to provide for such number of authorized and unissued shares
of Common  Stock to enable the Company to comply with its  issuance,  conversion
and  reservation  of shares  obligations  as set forth in this Agreement and the
Debentures. The sum of (x) the number of shares of Common Stock then outstanding
plus all  shares of Common  Stock  issuable  upon  exercise  of all  outstanding
options,  warrants and  convertible  instruments,  and (y) the Current  Required
Minimum,  shall be a reasonable  number. In connection  therewith,  the Board of
Directors  shall (a) adopt proper  resolutions  authorizing  such increase,  (b)
recommend  to and  otherwise  use its best  efforts to promptly  and duly obtain
stockholder  approval to carry out such  resolutions (and hold a special meeting
of the  stockholders  no later  than the  earlier to occur of the 60th day after
delivery of the proxy materials  relating to such meeting and the 90th day after
request by a holder of Securities  to issue the number of  Underlying  Shares in
accordance with the terms hereof) and (c) within five Business Days of obtaining
such stockholder  authorization,  file an appropriate amendment to the Company's
certificate or articles of incorporation to evidence such increase.  Any failure
to amend the Company's  Certificate or Articles of Incorporation by the 90th day
following  request thereof or date otherwise  required shall be a breach of this
provision,  even if the Company shall have complied with each other  requirement
of this paragraph.

outstanding litigation.

conflicts of law thereof. Each party agrees that all Proceedings  concerning the
interpretations,  enforcement  and defense of the  transactions  contemplated by
this Agreement and any other  Transaction  Documents  (whether brought against a
party hereto or its respective affiliates,  directors,  officers,  shareholders,

courts sitting in the City of New York, Borough of Manhattan.  Each party hereto
hereby  irrevocably  submits  to the  exclusive  jurisdiction  of the  state and

                                       18


         4.9.   Survival.  The  representations,   warranties,   agreements  and

covenants  contained  herein  shall  survive the Closing  and the  delivery  and

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

         4.11.  Severability.  In case any one or more of the provisions of this
                ------------
Agreement  shall be invalid or  unenforceable  in any respect,  the validity and
enforceability of the remaining terms and provisions of this Agreement shall not
in any way be affected or impaired thereby and the parties will attempt to agree
upon a valid and enforceable  provision  which shall be a reasonable  substitute
therefor,  and upon so agreeing,  shall incorporate such substitute provision in
this Agreement.

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

         4.13.  Independent  Nature of Purchasers'  Obligations and Rights.  The
                ----------------------------------------------------------
rights and  obligations of each  Purchaser  under any  Transaction  Document are
several and not joint with the rights and obligations of the other Purchaser and
a  Purchaser  shall not be  responsible  in any way for the  performance  of the
obligations  of the other  Purchaser  under any  Transaction  Document.  Nothing
contained  herein or in any  Transaction  Document,  and no action  taken by any
Purchaser pursuant thereto shall 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 with respect to
such obligations or the transactions  contemplated by the Transaction Documents.
Each  Purchaser  shall be  entitled  to  independently  protect  and enforce its
rights, including without limitation the rights arising out of this Agreement or
out of the other  Transaction  Documents,  and it shall not be necessary for the
other  Purchaser to be joined as an additional  party in any proceeding for such
purpose.
