       Except  as set  forth in the  Schedule  of  Exceptions  to the  Company's

       3.1 Organization. Each of the Company and its subsidiaries (as defined in
Rule 405 under the  Securities Act of 1933, as amended (the  "Securities  Act"),
the  "Subsidiaries"),  is a corporation  duly organized and validly  existing in
good standing under the laws of the  jurisdiction of its  organization.  Each of
the Company and its  Subsidiaries  has full power and authority to own,  operate
and occupy its properties and to conduct its business as presently conducted and
is  registered  or  qualified  to do  business  and in  good  standing  in  each
jurisdiction in which it owns or leases property or transacts business and where
the failure to be so  qualified  would have a material  adverse  effect upon the
business,  financial  condition,  prospects,  properties  or  operations  of the
Company and its Subsidiaries,  considered as one enterprise (a "Material Adverse
Effect"),  and no  proceeding  has been  instituted  in any  such  jurisdiction,
revoking,  limiting or curtailing,  or seeking to revoke, limit or curtail, such
power and authority or qualification. The Company does not have any Subsidiaries
nor does it control, directly or indirectly, or own, directly or indirectly, any
shares of stock or any other equity interest of any corporation,  partnership or
limited  liability  company,  other than as  disclosed in the  Company's  Annual
Report on Form 10-K ("Annual Report") or the Company's Quarterly Reports on Form
10-Q  ("Quarterly  Reports," and together with the Annual Report,  the "Exchange
Act  Reports")  filed  from  time to  time  with  the  Securities  and  Exchange
Commission  (the "SEC")  pursuant to the Securities and Exchange Act of 1934, as
amended (the "Exchange Act") or identified on Schedule 3.1.

       3.2 Due Authorization.  The Company has all requisite power and authority
to execute,  deliver and perform its  obligations  under this  Agreement and the
Investor  Rights  Agreement and such  agreements  have been duly  authorized and
validly  executed and delivered by the Company and constitute  legal,  valid and
binding agreements of the Company  enforceable against the Company in accordance
with their terms,  except as rights to indemnity and contribution may be limited
by state or federal  securities laws or the public policy  underlying such laws,
except as enforceability  may be limited by applicable  bankruptcy,  insolvency,
reorganization,  moratorium or similar laws affecting creditors' and contracting
parties' rights generally and except as enforceability may be subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

       3.3 Non-Contravention. Except as set forth on Schedule 3.3, the execution
and delivery of the Agreement and the Investor  Rights  Agreement,  the issuance
and sale of the  Shares  to be sold by the  Company  under  the  Agreement,  the
fulfillment of the terms of the Agreement and the

Investor Rights Agreement and the consummation of the transactions  contemplated
hereby and thereby will not (A) conflict  with or  constitute a violation of, or
default  (with the passage of time or  otherwise)  under,  or give to others any
rights of  termination,  amendment,  acceleration  or  cancellation  of, (i) any
material bond, debenture,  note or other evidence of indebtedness,  or under any
material lease, contract,  indenture,  mortgage,  deed of trust, loan agreement,
joint  venture or other  agreement  or  instrument  to which the  Company or any
Subsidiary  is a  party  or by  which  it or any of its  Subsidiaries  or  their
respective   properties   are  bound,   (ii)  the  charter,   by-laws  or  other
organizational  documents  of the Company or any  Subsidiary,  or (iii) any law,
administrative  regulation,  ordinance,  judgement,  injunction, or order of any
court or governmental  agency,  arbitration panel or authority applicable to the
Company or any Subsidiary or their respective  properties,  or (B) result in the
creation or imposition of any lien,  encumbrance,  claim,  security  interest or
restriction  whatsoever  upon any of the  material  properties  or assets of the
Company or any Subsidiary or an  acceleration  of  indebtedness  pursuant to any
obligation,  agreement or condition  contained in any material bond,  debenture,
note or any other evidence of indebtedness or any material indenture,  mortgage,
deed of trust or any other  agreement or  instrument to which the Company or any
Subsidiary  is a party or by which  any of them is bound or to which  any of the
property or assets of the  Company or any  Subsidiary  is  subject.  No consent,
waiver,   approval,   authorization   or  other   order  of,  or   registration,
qualification or filing with, any regulatory  body,  administrative  agency,  or
other  governmental  body in the United States is required for the execution and
delivery of the  Agreements  and the valid issuance and sale of the Shares to be
sold pursuant to the Agreements,  other than such as have been made or obtained,
and except for any securities filings required to be made under federal or state
securities laws.

       3.4 Capitalization.  The capitalization of the Company as of December 31,
1998 is as set forth in  Schedule  3.4.  The  Company has not issued any capital
stock since that date other than  pursuant  to the  Company's  employee  benefit
plans.  The  Shares  to be  sold  pursuant  to this  Agreement  have  been  duly
authorized,  and when  issued and paid for in  accordance  with the terms of the
Agreement will be duly and validly  issued,  fully paid and  nonassessable.  The
outstanding  shares of capital  stock of the Company  have been duly and validly
issued and are fully paid and nonassessable, have been issued in compliance with
all federal and state  securities  laws, and were not issued in violation of any
preemptive  rights or similar  rights to subscribe  for or purchase  securities.
Except as set forth in Schedule 3.4, there are no outstanding rights (including,
without  limitation,  preemptive  rights),  warrants or options to  acquire,  or
instruments convertible into or exchangeable for, any unissued shares of capital
stock  or  other  equity  interest  in the  Company  or any  Subsidiary,  or any
contract,  commitment,  agreement,  understanding  or arrangement of any kind to
which the Company is a party or of which the Company has  knowledge and relating
to the issuance or sale of any capital  stock of the Company or any  Subsidiary,
any such convertible or exchangeable  securities or any such rights, warrants or
options.  Without limiting the foregoing,  no preemptive  right,  co-sale right,
registration  right,  right of first  refusal or other similar right exists with
respect to the Shares or the issuance and sale thereof.  No further  approval or
authorization  of any  stockholder,  the Board of

Directors  of the Company or others is required for the issuance and sale of the
Shares.  Except as set forth on Schedule 3.1, the Company owns the entire equity
interest  in each of its  Subsidiaries,  free  and  clear of any  pledge,  lien,
security  interest,  encumbrance,  claim or  equitable  interest,  other than as
described in the Company audited financial statements contained in the Company's
Annual  Report.  Except  as  contemplated  hereby,  there  are  no  stockholders
agreements,  voting  agreements or other similar  agreements with respect to the
Common  Stock to which  the  Company  is a party  or,  to the  knowledge  of the
Company, between or among any of the Company's stockholders.

       3.5 Legal  Proceedings.  There is no action,  suit,  notice of violation,
proceeding  or  investigation  pending or, to the best actual  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,  governmental or
administrative agency or regulatory authority (Federal,  state, county, local or
foreign)  which  (i)  relates  to  or  challenges  the  legality,   validity  or
enforceability  of the Agreement or the Investor Rights Agreement or the Shares,
(ii) could,  individually or in the aggregate, have a Material Adverse Effect or
(iii) could,  individually or in the aggregate,  adversely impair the ability of
the  Company  to  perform  fully on a timely  basis  its  obligations  under the
Agreement or the  Investor  Rights  Agreement.

       3.6 No  Violations.  Neither the Company  nor any  Subsidiary,  except as
listed on  Schedule  3.6,  is in  violation  of its  charter,  bylaws,  or other
organizational document, or in violation of any law, administrative  regulation,
ordinance or order of any court or  governmental  agency,  arbitration  panel or
authority  applicable  to  the  Company  or  any  Subsidiary,  which  violation,
individually or in the aggregate,  would be reasonably likely to have a Material
Adverse Effect,  or is in default in any material  respect in the performance of
any obligation, agreement or condition contained in any bond, debenture, note or
any other evidence of indebtedness in any indenture,  mortgage, deed of trust or
any other  agreement or instrument  to which the Company or any  Subsidiary is a
party  or by which  the  Company  or any  Subsidiary  is  bound or by which  the
properties  of the Company or any  Subsidiary  are bound or affected,  and there
exists  no  condition  which,  with  the  passage  of time or  otherwise,  would
constitute a material default under any such document or instrument or result in
the  imposition  of any  material  penalty or the  acceleration  of any material
indebtedness.

       3.7 Governmental  Permits,  Etc. Each of the Company and its Subsidiaries
has all necessary  franchises,  licenses,  certificates and other authorizations
from any foreign,  federal,  state or local  government or governmental  agency,
department,  or body  that are  currently  necessary  for the  operation  of the
business of the Company and its  Subsidiaries  as  currently  conducted,  except
where the failure to currently  possess could not reasonably be expected to have
a Material Adverse Effect on the Company.

       3.8 Intellectual  Property.  Subject to the matters discussed under "Risk
Factors" in the Company's Exchange Act Reports,  (i) each of the Company and its
Subsidiaries  owns or possesses  sufficient  rights to use all material patents,

inventions, trade secrets, trade names and know-how (collectively, "Intellectual
Property")  that are necessary for the conduct of its business as now conducted,
except where the failure to currently  own or possess  would not have a Material
Adverse  Effect  on  the  Company,  (ii)  neither  the  Company  nor  any of its
Subsidiaries  has  received  any  notice  of,  or  has  any  knowledge  of,  any
infringement  of or conflict with  asserted  rights of the Company or any of its
Subsidiaries  by others with  respect to any  Intellectual  Property,  except as
would not have a Material  Adverse  Effect on the  Company,  (iii)  neither  the
Company  nor any of its  Subsidiaries  has  received  any  notice of, or has any
knowledge of, any  infringement  of or conflict with asserted  rights of a third
party with respect to any  Intellectual  Property that,  individually  or in the
aggregate,  would have a Material  Adverse  Effect on the  Company.  None of the
Company's  trademarks,  trade names,  service marks, service mark registrations,
service  names,  patents,  patent  rights,  copyrights,   inventions,  licenses,
approvals,  government  authorizations,  trade  secrets  or  other  intellectual
property  rights  have  expired  or  terminated,  or are  expected  to expire or
terminate within two years from the date of this Agreement.

       3.9 Financial Statements. The financial statements of the Company and the
related notes contained in the Company's  Exchange Act Reports comply as to form
in all material  respects with all applicable  accounting  requirements  and the
published  rules and  regulations of the Commission  with respect  thereto,  and
present fairly, in accordance with generally accepted accounting principles, the
financial  position  of  the  Company  and  its  Subsidiaries  as of  the  dates
indicated,  and the  results of its  operations  and cash flows for the  periods
therein specified.  Such financial statements (including the related notes) have
been  prepared in  accordance  with  generally  accepted  accounting  principles
applied on a consistent basis throughout the periods therein  specified,  except

Reports do not contain all of the notes required pursuant to generally  accepted
accounting principals.

       3.10 No Material Adverse Effect.  Except as disclosed in Schedule 3.10 or
otherwise  disclosed,  since December 31, 1998,  there has not been any event or
occurrence which has caused or resulted in a Material Adverse Effect, including,
without limitation, (i) the incurrence of any obligation,  direct or contingent,
that  is  material  to  the  Company  and  its  Subsidiaries  considered  as one
enterprise, except obligations incurred in the ordinary course of business, (ii)
any dividend or distribution  of any kind declared,  paid or made on the capital

                 Representations and Warranties of the Investors

       Each Investor  hereby  severally  represents  and warrants to the Company
with respect to the purchase of the Shares as follows:

       4.1 Experience. It has substantial experience in evaluating and investing
in private  placement  transactions  of securities  in companies  similar to the
Company  so that it is  capable  of  evaluating  the  merits  and  risks  of its
investment  in the  Company and has the  capacity to protect its own  interests.
Investor  is an  "accredited  investor"  as  defined  in  Regulation  501(a)  of
Regulation  D  promulgated  under the  Securities  Act of 1933,  as amended (the
"Securities Act").

       4.2  Investment.  It is acquiring the Shares for  investment  for its own
account,  not as a nominee or agent,  and not with the view to, or for resale in
connection with, any distribution  thereof.  It understands that the Shares have
not been,  and will not be when issued,  registered  under the Securities Act by
reason  of  a  specific  exemption  from  the  registration  provisions  of  the
Securities Act, the availability of which depends upon, among other things,  the
bona  fide   nature  of  the   investment   intent  and  the   accuracy  of  the
representations as expressed herein.

       4.3 Rule 144. It acknowledges  that the Shares must be held  indefinitely
unless  subsequently  registered under the Securities Act or unless an exemption
from such  registration is available.  It is aware of the provisions of Rule 144
promulgated  under the  Securities  Act which  permit  limited  resale of shares
purchased  in a  private  placement  subject  to  the  satisfaction  of  certain
conditions,  which may include,  among other  things,  the existence of a public
market for the shares,  the  availability of certain current public  information
about the Company, the resale occurring not less than one year after a party has
purchased and paid for the security to be sold, the sale being effected  through
a "broker's  transaction" or in transactions  directly with a "market maker" and
the number of shares  being sold  during any  three-month  period not  exceeding
specified limitations.

       4.4 No Public Market. It understands that no public market now exists for
the Shares, and that a market may never exist for the Shares.

       4.5 Access to Data.  Its  officers  and  agents,  to the extent that they
desired, have had an opportunity to discuss the Company's  management,  business
plan and financial condition with the Company's management.  It understands that
a purchase  of the Shares  involves a high  degree of risk,  and there can be no
assurance the Company's business objectives will be obtained.

       4.6  Authorization.  This Agreement and the Investors'  Rights Agreement,
when  executed  and  delivered  by the  Investors,  will  constitute a valid and
legally binding obligation of each such Investor, enforceable in accordance with
its terms,  except as rights to  indemnity  and 

                                      -8-

contribution  may be limited by state or federal  securities  laws or the public
policy  underlying  such  laws,  except  as  enforceability  may be  limited  by
applicable bankruptcy,  insolvency,  reorganization,  moratorium or similar laws
affecting  creditors' and contracting  parties'  rights  generally and except as
enforceability  may be subject to general  principles of equity  (regardless  of
whether such enforceability is considered in a proceeding in equity or at law).

       4.7  Authority.  It has all requisite  legal power and authority to enter
into this  Agreement and the Investors'  Rights  Agreement and to consummate the
transactions contemplated hereby and thereby. The execution and delivery of this
Agreement  and the  Investors'  Rights  Agreement  and the  consummation  of the
transactions  contemplated  hereby and thereby have been duly  authorized by all
necessary action on the part of it. The execution and delivery of this Agreement
and  the  Investors  Rights  Agreement  do  not,  and  the  consummation  of the
transactions  contemplated  hereby  will not,  conflict  with,  or result in any
violation  of, or default  (with or without  notice or lapse of time,  or both),
under any provision of the organization documents of such Investor.

       4.8 No  Conflicts.  The  execution,  delivery  and  performance  of  this
Agreement by such Investor  will not breach,  cause a default under or otherwise
conflict with or give rise to any  acceleration  or  termination  of the charter
documents of such  Investor or any material  contract or agreement to which such
Investor is a party.

       4.9 Broker's and Finders' Fees. It has not incurred,  and will not incur,
directly or indirectly,  any liability for brokerage or finders' fees or agents'
commissions  or any similar  charges in  connection  with this  Agreement or any
transaction contemplated hereby.

       4.10 Not Acting in  Concert.  Notwithstanding  the fact that  immediately
after the  Closing,  the  Investors  will hold an aggregate of 64% of the voting
power of the Company on a fully-diluted  basis, and the fact that certain of the
Investors are affiliated  entities as indicated by the three numbered  groupings
of Investors  contained in Schedule 1.2 hereto,  such  Investor is not acting in
concert with any other Investor,  or group of Investors,  whether  affiliated or
otherwise, for the purpose of gaining control over the direction of the Company.

liabilities (or actions or proceedings in respect  thereof) arise out of, or are
based  upon,  (i) any  failure  to  comply  with the  covenants  and  agreements
contained  in Section  7.2 hereof  respecting  sale of the  Shares,  or (ii) any
untrue statement of a material fact contained in the  Registration  Statement if
such untrue  statement was made in reliance upon and in conformity  with written
information  furnished by or on behalf of the Investor  specifically  for use in
preparation of the Registration  Statement,  and the Investor will reimburse the
Company (or such officer,  director or controlling  person), as the case may be,
for any legal or other expenses reasonably incurred in investigating,  defending
or preparing to defend any such action, proceeding or claim; provided that in no
event shall any indemnity under this  Subsection  7.3(b) exceed the net proceeds
from the offering received by the Selling Stockholder.

            (c) Promptly after receipt by any indemnified  person of a notice of
a claim or the  beginning  of any action in respect of which  indemnity is to be
sought  against an  indemnifying  person  pursuant  to this  Section  7.3,  such
indemnified person shall notify the indemnifying person in writing of such claim
or of the  commencement  of such  action,  but the  omission  to so  notify  the
indemnifying  party will not relieve it from any liability  which it may have to
any  indemnified  party  under this  Section 7.3 (except to the extent that such
omission  materially and adversely  affects the indemnifying  party's ability to
defend such action) or from any liability otherwise than under this Section 7.3.
Subject to the provisions  hereinafter  stated, in case any such action shall be
brought against an indemnified person, the indemnifying person shall be entitled
to participate therein, and, to the extent that it shall elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such  indemnified  party,  shall be entitled to assume the defense thereof,
with counsel reasonably  satisfactory to such indemnified  person.  After notice
from the  indemnifying  person to such  indemnified  person of its  election  to
assume the defense thereof, such indemnifying person shall not be liable to such
indemnified  person  for  any  legal  expenses  subsequently  incurred  by  such
indemnified  person in connection with the defense thereof,  provided,  however,
that if there  exists or shall exist a conflict  of interest  that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof,  the indemnified person shall be entitled to
retain its own counsel at the  expense of such  indemnifying  person;  provided,
however,  that  unless  another  such  specific  conflict  of  interest  between
indemnified  parties  requires  otherwise,   no  indemnifying  person  shall  be
responsible  for the  fees  and  expenses  of more  than  one  separate  counsel
(together with  appropriate  local counsel) for all indemnified  parties.  In no
event shall any indemnifying  person be liable in respect of any amounts paid in
settlement of any action unless the indemnifying  person shall have approved the
terms of such  settlement;

provided that such consent shall not be unreasonably  withheld.  No indemnifying
person  shall,  without the prior  written  consent of the  indemnified  person,
effect any  settlement  of any pending or  threatened  proceeding  in respect of
which any indemnified  person is or could have been a party and  indemnification
could  have been  sought  hereunder  by such  indemnified  person,  unless  such
settlement includes an unconditional release of such indemnified person from all
liability on claims that are the subject matter of such proceeding.

            (d) If the  indemnification  provided  for in  this  Section  7.3 is
unavailable  to or  insufficient  to hold  harmless an  indemnified  party under
subsection  (a) or (b)  above in  respect  of any  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect thereof)  referred to therein,
then each  indemnifying  party shall contribute to the amount paid or payable by
such  indemnified  party  as  a  result  of  such  losses,  claims,  damages  or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative  fault of the Company on the one hand and the  Investors
on the other in  connection  with the  statements  or omissions or other matters
which resulted in such losses,  claims,  damages or  liabilities  (or actions in
respect thereof),  as well as any other relevant equitable  considerations.  The
relative  fault shall be determined by reference to, among other things,  in the
case of an untrue statement, whether the untrue statement relates to information
supplied  by the  Company  on the one hand or an  Investor  on the other and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct or prevent such untrue  statement.  The Company and the Investors  agree
that it  would  not be just  and  equitable  if  contribution  pursuant  to this
subsection  (d) were  determined by pro rata  allocation  (even if the Investors
were  treated  as one  entity  for  such  purpose)  or by any  other  method  of
allocation  which  does not  take  into  account  the  equitable  considerations
referred  to above in this  subsection  (d).  The  amount  paid or payable by an
indemnified party as a result of the losses,  claims, damages or liabilities (or
actions in respect  thereof)  referred to above in this  subsection (d) shall be
deemed  to  include  any legal or other  expenses  reasonably  incurred  by such
indemnified party in connection with  investigating or defending any such action
or claim.  Notwithstanding  the provisions of this  subsection  (d), no Investor
shall be required to contribute  any amount in excess of the amount by which the
net amount  received by the  Investor  from the sale of the Shares to which such
loss relates exceeds the amount of any damages which such Investor has otherwise
been  required to pay by reason of such untrue  statement.  No person  guilty of
fraudulent  misrepresentation  (within  the  meaning  of  Section  11(f)  of the
Securities  Act) shall be entitled to  contribution  from any person who was not
guilty of such fraudulent misrepresentation.  The Investors' obligations in this
subsection to  contribute  are several in proportion to their sales of Shares to
which such loss relates and not joint.

            (e) The parties to this Agreement  hereby  acknowledge that they are
sophisticated  business  persons  who were  represented  by  counsel  during the
negotiations regarding the provisions hereof including,  without limitation, the
provisions  of  this  Section  7.3,  and  are  fully  informed   regarding  said
provisions.  They further  acknowledge  that the  provisions of this Section 7.3
fairly  allocate the risks in light of the ability of the parties to investigate
the Company and its business in order to assure that adequate disclosure is made
in the Registration Statement as required by the Securities Act and the Exchange
Act. The parties are advised that federal or state public policy as  interpreted
by the  courts in  certain  jurisdictions  may be  contrary  to  certain  of the
provisions of this Section 7.3, and the parties  hereto hereby  expressly  waive
and relinquish any right or ability to assert such public policy as a defense to
a claim under this  Section  7.3 and further  agree not to attempt to assert any
such defense.

       7.4 Termination of Conditions and Obligations.  The conditions  precedent
imposed by this Section 7 upon the transferability of the Shares shall cease and
terminate as to any particular  number of the Shares when such Shares shall have
been  effectively  registered  under the  Securities  Act and sold or  otherwise
disposed of in accordance  with the intended  method of disposition set forth in
the Registration Statement covering such Shares or at such time as an opinion of
counsel  satisfactory to the Company shall have been rendered to the effect that
such conditions are not necessary in order to comply with the Securities Act.

       7.5  Shareholder  Approval.  The Company  shall use its  reasonable  best
efforts to seek shareholder approval for an increase in the authorized number of
shares of Common  Stock or a reverse  stock  split,  and to  reserve  sufficient
shares  of  Common  Stock,  to enable  the  Company  to  perform  it  conversion
obligations with respect to the Shares.  Upon such action, the Company shall use
its reasonable best efforts to ensure that the Underlying  Shares when issued in
accordance  with the  Certificate  of  Incorporation  shall be duly  authorized,
validly issued, fully paid and nonassessable and free and clear of all liens.

       7.6 Listing.  Promptly  following the Closing,  the Company shall use its
best  reasonable  efforts to cause all of the  outstanding  shares of the Common
Stock of the Company and the Underlying Shares to be approved for listing in the
Nasdaq National Market or SmallCap Market, as the case may be, and shall provide
to the  Investors  evidence of such listing when approved and shall use its best
reasonable efforts to maintain the listing of its Common Stock on such exchange.

power or remedy  accruing  to either  party  upon any  breach or default of such

default,  or an acquiescence  therein, or of or in any similar breach or default
thereafter  occurring;  nor shall any waiver of any single  breach or default be
deemed a waiver  of any  other  breach  or  default  theretofore  or  thereafter

             2.2 Requested Registration.

                 (a) Request for  Registration  by  Initiating  Holders.  If the
Company shall receive from Initiating  Holders, at any time after the date sixty
(60)  calendar  days from the date  hereof,  a written  request that the Company
effect any  registration  with  respect to all or a part of that  portion of the
Registrable  Securities  which consists of Common Stock, or alternately,  at any
time  after the date two (2)  calendar  years  from the date  hereof,  a written
request that the Company effect any registration  with respect to all or part of
that portion of the Registrable  Securities which consists of Series A Preferred
Stock and/or Common Stock, the Company will:

                       (i)  promptly   give  written   notice  of  the  proposed
registration,  qualification  or compliance to all other Holders of  Registrable
Securities; and

                       (ii) as soon as  practicable,  use its  best  efforts  to
effect such registration  (including,  without  limitation,  the execution of an
undertaking to file post-effective  amendments,  appropriate qualification under
applicable blue sky or other state  securities  laws and appropriate  compliance
with  applicable  regulations  issued  under  the  Securities  Act) as may be so
requested and as would permit or facilitate the sale and  distribution of all or
such portion of such  Registrable  Securities  as are specified in such request,
together with all or such portion of the Registrable Securities of any Holder or
Holders  joining in such request as are of the same class as those which are the
subject of the request and are  specified in a written  request  received by the
Company  within 15 days after  written  notice  from the  Company is given under
Section  2.2(a)(i)  above;  provided,  however,  that the  Company  shall not be
obligated  to  effect,  or take any  action  to  effect,  any such  registration
pursuant to this Section 2.2(a):

                            (A) In any  particular  jurisdiction  in  which  the
Company would be required to execute a general  consent to service of process in
effecting such  registration,  qualification or compliance unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act or applicable rules or regulations thereunder; or

                            (B) With respect to that portion of the  Registrable
Securities  which  consists  of shares of Common  Stock,  after the  Company has
effected one such registration of shares of Common Stock pursuant to Section 2.2
and such  registration  has been  declared or ordered  effective and the sale of
such Registrable  Securities shall have closed; and with respect to that portion
of the  Registrable  Securities  which  consists of shares of Series A Preferred
Stock,  after the Company has effected one such registration of shares of Series
A  Preferred  Stock  pursuant  to  Section  2.2 and such  registration  has been
declared or ordered effective and the sale of such Registrable  Securities shall
have closed.

         The  registration  statement  filed  pursuant  to  the  request  of the
Initiating  Holders may,  subject to the  provisions  of Section  2.2(b)  below,
include other  securities of the Company which are held by officers or directors
of the Company,  or which are held by persons who, by virtue of agreements  with
the Company,  are entitled to include their securities in any such registration,
but the Company

                                      -3-

                                                                   Page 44 of 59

and such other  holders  shall  have no  absolute  right to  include  any of its
securities in any such registration.

                 (b)  Underwriting;   Request  by  Initiating  Holders.  If  the
Initiating  Holders intend to distribute the Registrable  Securities  covered by
their request by means of an underwriting, they shall so advise the Company as a
part of their  request  made  pursuant to Section  2.2(a) and the Company  shall
include such information in the written notice referred to in Section 2.2(a). In
such  event,  the  right of any  Holder to  include  such  Holder's  Registrable
Securities  in  such  registration  shall  be  conditioned  upon  such  Holder's
participation   in  such   underwriting  and  the  inclusion  of  such  Holder's
Registrable  Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating  Holders and such Holder) to the extent
provided herein.  All Holders  proposing to distribute their securities  through
such  underwriting  shall  (together  with the  Company as  provided  in Section
2.4(e))  enter  into an  underwriting  agreement  in  customary  form  with  the
underwriter  or  underwriters  selected for such  underwriting  by a majority in
interest of the  Initiating  Holders and  reasonably  acceptable to the Company.
Notwithstanding  any other provision of Section 2.2, if the underwriter  advises
the Company and the Initiating Holders in writing that marketing factors require
a limitation of the number of shares to be underwritten,  then the Company shall
so advise  all  Holders of  Registrable  Securities  which  would  otherwise  be
underwritten pursuant hereto, and the number of shares of Registrable Securities
that may be included in the  underwriting  shall be allocated  among all Holders
thereof,  including the  Initiating  Holders,  in such  proportion (as nearly as
practicable)  among the  Holders  pro rata  based on the  amount of  Registrable
Securities owned by each Holder.

                 (c) Notwithstanding the foregoing, if the Company shall furnish
to the Holders  requesting  the filing of a registration  statement  pursuant to
Section 2.2(a), a certificate signed by the President or Chief Executive Officer
of the Company stating that a delay in the filing of the registration  statement
is necessary because in the reasonable  judgment of the Company, it would not be
in the best interest of the Company and its stockholders  for such  registration
statement to be filed.  In no event shall such delay exceed thirty (30) calendar
days with respect to any single exercise of the Company's rights hereunder,  and
provided  further,  however,  that in no event  shall  Company be  permitted  to
exercise this right more than three times or for more than an aggregate of sixty
(60) calendar days in any single calendar year. In addition,  the Company agrees
to use its reasonable best efforts to resolve  whatever  condition or conditions
have  occasioned  any such delay on its part,  and will  promptly end such delay
upon resolution of such condition or conditions.

                 (d)  Notwithstanding  the  foregoing,  in the  event  that  the
Company shall prepare and file with the SEC a  registration  statement  covering
securities to be distributed on its own behalf  (including,  but not limited to,
registration  statements  relating to secondary  offerings of  securities of the
Company,  but  excluding  any  registration  statement  relating to any employee
benefit plan or a corporate reorganization, a "Company Registration"),  and such
registration  statement  shall  become  effective,  then  during  the  period of
effectiveness of such Company Registration, the Company shall have no obligation
to prepare,  file, or keep effective any registration  statement with respect to
Registrable Securities of the Holders;  however, such obligations of the Company
with 

                                      -4-

                                                                   Page 45 of 59

respect to the Holders as are contained  elsewhere in this Section 2 shall arise
again immediately upon the end of the effectiveness of any Company Registration,
and if  necessary,  at such  time  the  Company  shall  prepare,  file  and keep
effective a registration statement with respect to any Registrable Securities of
the  Holders  for  which  a  previously  effective  registration  statement  was
preempted by a Company Registration.

                 (e)  In  the  event   that   because   of  a  planned   Company
Registration,  pursuant to Section  2.2(d) the Company will fail to maintain the
effectiveness of an effective  registration  statement previously filed with the
SEC to register  Registrable  Securities of the Holders pursuant to a request by
the  Initiating  Holders  under this Section  2.2, the Company  shall notify all
Holders in writing at least 30 days prior to such Company Registration, and will
afford each such Holder an opportunity  to include in such Company  Registration
all or any part of the  Registrable  Securities  then held by such Holder.  Each
Holder desiring to include in any such Company  Registration  all or any part of
the  Registrable  Securities  held by such  Holder  shall,  within 15 days after
receipt of the above-described notice from the Company, so notify the Company in
writing,  and  in  such  notice  shall  inform  the  Company  of the  number  of
Registrable   Securities   such  Holder   wishes  to  include  in  such  Company
Registration.  If a Company Registration as which the Company gives notice under
this Section 2.2(e) is for an underwritten  offering,  then the Company shall so
advise the Holders.  In such event,  the right of any such Holder's  Registrable
Securities to be included in the Company  Registration shall be conditioned upon
such  Holder's  participation  in such  underwriting  and the  inclusion of such
Holder's  Registrable  Securities  in the  underwriting  to the extent  provided
herein. All Holders proposing to distribute their Registrable Securities through
such underwriting  shall enter into an underwriting  agreement in customary form
with the managing underwriter or underwriter(s)  selected for such underwriting.
Notwithstanding  any  other  provision  of  this  Agreement,   if  the  managing
underwriter(s)  determine(s)  in good faith  that  marketing  factors  require a
limitation  of the  number  of  shares  to be  underwritten,  then the  managing
underwriter(s)  may exclude shares (including  Registrable  Securities) from the
registration and the underwriting, and the number of shares that may be included
in the  registration  and the  underwriting  shall be allocated,  first,  to the
Company, and second, to each of the Holders of Registrable Securities requesting
inclusion of their Registrable Securities in such registration  statement, to be
allocated  among all Holders thereof pro rata based on the amount of Registrable
Securities  of the Company  owned by each  Holder.  Any  Registrable  Securities
excluded or withdrawn  from such  underwriting  shall be excluded and  withdrawn
from the Company Registration.

             2.3 Expenses of Registration. All Registration Expenses incurred in
connection with one demand registration (pursuant to Section 2.2) shall be borne
by the Company,  and all Selling  Expenses  shall be borne by the Holders of the
securities so registered  pro rata on the basis of the number of their shares so
registered.

             2.4  Obligations  of the Company.  Whenever  required to effect the
registration of any  Registrable  Securities  under this Agreement,  the Company
shall, as expeditiously as reasonably possible:

                                      -5-

                                                                   Page 46 of 59

                 (a) Prepare and file with the SEC a registration statement with
respect to such  Registrable  Securities  and use its best efforts to cause such
registration statement to become effective, and keep such registration statement
effective  until the  distribution  is completed,  subject to any termination or
suspension of the Holders' registration rights as provided elsewhere herein.

                 (b)  Prepare  and  file  with  the  SEC  such   amendments  and
supplements to such registration statement and the prospectus used in connection
with  such  registration  statement  as may be  necessary  to  comply  with  the
provisions  of  the  Securities  Act  with  respect  to the  disposition  of all
securities covered by such registration statement.

                 (c)  Furnish  to  the  Holders  such  number  of  copies  of  a
prospectus,   including  a  preliminary  prospectus,   in  conformity  with  the
requirements of the Securities Act, and all amendments and supplements  thereto,
and such other  documents as they may reasonably  request in order to facilitate
the disposition of the Registrable Securities owned by them that are included in
such registration.

                 (d) Use its best efforts to register and qualify the securities
covered by such  registration  statement under such other securities or Blue Sky
laws of such  jurisdictions  as shall be  reasonably  requested  by the Holders,
provided,  however,  that  the  Company  shall  not be  required  in  connection
therewith  or as a  condition  thereto to qualify  to do  business  or to file a
general  consent to service  of  process  in any such  states or  jurisdictions,
unless the Company is already subject to service in such jurisdiction and except
as may be required by the  Securities  Act or  applicable  rules or  regulations
thereunder.

                 (e) In the event of any  underwritten  public  offering,  enter
into and perform its obligations under an underwriting  agreement,  in usual and
customary form, with the managing  underwriter(s) of such offering.  Each Holder
participating  in such  underwriting  shall  also  enter  into and  perform  its
obligations under such an agreement.

                 (f) Notify each  Holder of  Registrable  Securities  covered by
such  registration  statement at any time when a prospectus  relating thereto is
required to be delivered  under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration  statement, as
then in effect,  includes  an untrue  statement  of a material  fact or omits to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein  not  misleading  in the  light  of the  circumstances  then
existing  and,  following  such  notification,  promptly  deliver to each Holder
copies of all amendments or supplements referred to in paragraphs (b) and (c) of
this Section 2.4.

                 (g)  Furnish,   at  the  request  of  any  Holder   registering
Registrable  Securities,  on the  date  that  such  Registrable  Securities  are
delivered  to the  underwriters  for sale,  if such  securities  are being  sold
through  underwriters,  (i) an  opinion,  dated as of such date,  of the counsel
representing  the Company for the  purposes  of such  registration,  in form and
substance as is customarily  given to  underwriters  in an  underwritten  public
offering   addressed  to  the  underwriters,   if 

                                      -6-

                                                                   Page 47 of 59

any, and if there are no underwriters, to the Holders requesting registration of
Registrable  Securities;  provided,  however that the requesting  Holder and the
Company shall each bear one half of the reasonable  fees and expenses of counsel
in generating such opinion,  and (ii) a "comfort"  letter dated as of such date,
from the independent  certified public  accountants of the Company,  in form and
substance as is customarily given by independent certified public accountants to
underwriters in an underwritten public offering and reasonably satisfactory to a
majority in interest of the Holders  requesting  registration,  addressed to the
underwriters; provided, however that the requesting Holder and the Company shall
each  bear  one  half of the  reasonable  fees  and  expenses  of the  Company's
independent certified public accountants in generating such letter.

             2.5 Furnish  Information.  It shall be a condition precedent to the
obligations of the Company to take any action  pursuant to Sections 2.2 that the
selling  Holders  shall  furnish  to  the  Company  such  information  regarding
themselves,  the Registrable Securities held by them, and the intended method of
disposition  of such  securities  as shall be  required  to  timely  effect  the
registration of Registrable Securities.

             2.6 Delay of Registration. No Holder shall have any right to obtain
or seek an injunction restraining or otherwise delaying any such registration as
the  result  of  any   controversy   that  might  arise  with   respect  to  the
interpretation or implementation of this Section 2.

             2.7 Indemnification.

                 (a) For the purpose of this Section 2.7:

                       (i) the term  "registration  statement" shall include any
final prospectus,  exhibit,  supplement or amendment  included in or relating to
the  registration  statement  (or  any of  the  securities  offered  thereunder)
referred to in Section 2.2 and

                       (ii) the term "untrue statement" shall include any untrue
statement or alleged untrue  statement,  or any omission or alleged  omission to
state in the  registration  statement  a  material  fact  required  to be stated
therein  or  necessary  to make  the  statements  therein,  in the  light of the
circumstances under which they were made, not misleading.

                 (b) The Company  agrees to  indemnify  and hold  harmless  each
Holder (or any partner,  officer or director of such Holder,  and any person who
controls  such Holder within the meaning of the  Securities  Act or the Exchange
Act) from and against  any  losses,  claims,  damages or  liabilities,  joint or
several,  to which such person may become  subject  (under the Securities Act or
otherwise) insofar as such losses, claims, damages or liabilities (or actions or
proceedings  in respect  thereof) arise out of, or are based upon (i) any untrue
statement or alleged  untrue  statement of a material  fact,  or any omission to
state or alleged omission to state a material fact contained in the registration
statement,  (ii) any  violation  or  alleged  violation  by the  Company  of the
Securities  Act,  the  Exchange  Act,  any state  securities  law or any rule or
regulation promulgated thereunder in connection with the offering covered by the
registration  statement,  or (iii) any  failure by the

                                                                   Page 48 of 59

Company to fulfill any undertaking included in the registration  statement,  and
the  Company  will  reimburse  such  person  for any  reasonable  legal or other
expenses reasonably incurred in investigating,  defending or preparing to defend
any such action,  proceeding  or claim,  or preparing to defend any such action,
proceeding or claim, provided,  however, that the Company shall not be liable in
any such case to the extent that such loss,  claim,  damage or liability  arises
out of, or is based upon, an untrue  statement or alleged untrue  statement,  or
any omission to state or alleged  omission to state a material fact made in such
registration   statement  in  reliance  upon  and  in  conformity  with  written
information furnished to the Company by or on behalf of such Holder specifically
for use in  preparation  of the  registration  statement  or the failure of such
Holder to comply  with its  covenants  and  agreements  contained  in 2.8 hereof
respecting  sale of the  Registrable  Securities or any statement or omission in
any Prospectus that is corrected in any subsequent Prospectus that was delivered
to the Holder prior to the pertinent sale or sales by the Holder.

                 (c) Each  Holder  agrees to  indemnify  and hold  harmless  the
Company (and each person, if any, who controls the Company within the meaning of
Section 15 of the  Securities  Act,  each  officer of the  Company who signs the
registration  statement  and each  director of the Company) from and against any
losses,  claims,  damages  or  liabilities  to which  the  Company  (or any such
officer,   director  or  controlling  person)  may  become  subject  (under  the
Securities  Act or  otherwise),  insofar  as such  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect  thereof) arise out of, or are
based  upon,  (i) any  failure  to  comply  with the  covenants  and  agreements
contained in Section 2.8 hereof  respecting sale of the Registrable  Securities,
or (ii) any untrue  statement or alleged untrue statement of a material fact, or
any omission to state or alleged  omission to state a material fact contained in
the registration statement if such untrue statement or alleged untrue statement,
or any omission to state or alleged  omission to state a material  fact was made
in reliance upon and in conformity with written  information  furnished by or on
behalf of such Holder the Investor  specifically  for use in  preparation of the
registration  statement,  and such  Holder will  reimburse  the Company (or such
officer,  director or controlling  person), as the case may be, for any legal or
other expenses reasonably  incurred in connection with investigating,  defending
or preparing to defend any such action, proceeding or claim; provided,  however,
that the indemnity agreement contained in this Section 2.7(c) shall not apply to
amounts paid in settlement of any such loss, claim, damage,  liability or action
if such settlement is effected without the consent of such Holder, which consent
shall not be unreasonably  withheld;  provided,  further, that in no event shall
the  liability of any Holder under this Section 2.7 exceed the proceeds from the
offering actually received by such Holder.

                 (d)  Promptly  after  receipt  by any  indemnified  person of a
notice of a claim or the  beginning of any action in respect of which  indemnity
is to be sought  against an  indemnifying  person  pursuant to this Section 2.7,
such indemnified person shall notify the indemnifying  person in writing of such
claim or of the  commencement of such action,  but the omission to so notify the
indemnifying  party will not relieve it from any liability  which it may have to
any  indemnified  party  under this  Section 2.7 (except to the extent that such
omission  materially and adversely  affects the indemnifying  party's ability to
defend such action) or from any liability otherwise than under this Section 7.3.
Subject to the provisions  hereinafter  stated, in case any such action shall be
brought

                                      -8-

                                                                   Page 49 of 59

against an  indemnified  person,  the  indemnifying  person shall be entitled to
participate  therein,  and, to the extent that it shall elect by written  notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such  indemnified  party,  shall be entitled to assume the defense thereof,
with counsel reasonably  satisfactory to such indemnified  person.  After notice
from the  indemnifying  person to such  indemnified  person of its  election  to
assume the defense thereof, such indemnifying person shall not be liable to such
indemnified  person  for  any  legal  expenses  subsequently  incurred  by  such
indemnified  person in connection with the defense thereof,  provided,  however,
that if there  exists or shall exist a conflict  of interest  that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof,  the indemnified person shall be entitled to
retain its own counsel at the  expense of such  indemnifying  person;  provided,
however,  that unless an additional  specific  conflict of interest  between two
indemnified  parties  otherwise  requires,   no  indemnifying  person  shall  be
responsible  for the  fees  and  expenses  of more  than  one  separate  counsel
(together with  appropriate  local counsel) for all indemnified  parties.  In no
event shall any indemnifying  person be liable in respect of any amounts paid in
settlement of any action unless the indemnifying  person shall have approved the
terms of such  settlement;  provided that such consent shall not be unreasonably
withheld. No indemnifying person shall, without the prior written consent of the
indemnified  person,   effect  any  settlement  of  any  pending  or  threatened
proceeding  in respect of which any  indemnified  person is or could have been a
party and  indemnification  could have been sought hereunder by such indemnified
person,  unless  such  settlement  includes  an  unconditional  release  of such
indemnified  person from all liability on claims that are the subject  matter of
such proceeding.

                 (e) If the indemnification  provided for in this Section 2.7 is
unavailable  to or  insufficient  to hold  harmless an  indemnified  party under
subsection  (a) or (b)  above in  respect  of any  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect thereof)  referred to therein,
then each  indemnifying  party shall contribute to the amount paid or payable by
such  indemnified  party  as  a  result  of  such  losses,  claims,  damages  or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative  fault of the Company on the one hand and the Holders on
the other in connection  with the statements or omissions or other matters which
resulted in such losses,  claims,  damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable  considerations.  The relative
fault shall be determined by reference to, among other things, in the case of an
untrue statement,  whether the untrue statement relates to information  supplied
by the Company on the one hand or Holder on the other and the parties'  relative
intent,  knowledge,  access to information and opportunity to correct or prevent
such untrue  statement.  The Company and the Holders  agree that it would not be
just  and  equitable  if  contribution  pursuant  to this  subsection  (d)  were
determined  by pro rata  allocation  (even if the  Holders  were  treated as one
entity for such  purpose) or by any other  method of  allocation  which does not
take  into  account  the  equitable  considerations  referred  to  above in this
subsection  (d). The amount paid or payable by an indemnified  party as a result
of the losses,  claims,  damages or liabilities (or actions in respect  thereof)
referred to above in this subsection (d) shall be deemed to include any legal or
other expenses  reasonably incurred by such indemnified party in connection with
investigating  or

defending  any such  action or claim.  Notwithstanding  the  provisions  of this
subsection  (d), no Holder shall be required to contribute  any amount in excess
of the amount by which the net amount  received  by such Holder from the sale of
the Registrable  Securities to which such loss relates exceeds the amount of any
damages which such Holder has  otherwise  been required to pay by reason of such
untrue statement. No person guilty of fraudulent  misrepresentation  (within the
meaning  of  Section  11(f)  of  the  Securities   Act)  shall  be  entitled  to
contribution   from  any  person   who  was  not   guilty  of  such   fraudulent
misrepresentation. The Holders' obligations in this subsection to contribute are
several in  proportion  to their sales of  Registrable  Securities to which such
loss relates and not joint.

                 (f) The parties to this Agreement hereby  acknowledge that they
are  sophisticated  business  persons who were represented by counsel during the
negotiations regarding the provisions hereof including,  without limitation, the
provisions  of  this  Section  2.7,  and  are  fully  informed   regarding  said
provisions.  They further  acknowledge  that the  provisions of this Section 2.7
fairly  allocate the risks in light of the ability of the parties to investigate
the Company and its business in order to assure that adequate disclosure is made
in the registration statement as required by the Securities Act and the Exchange
Act. The parties are advised that federal or state public policy as  interpreted
by the  courts in  certain  jurisdictions  may be  contrary  to  certain  of the
provisions of this Section 2.7, and the parties  hereto hereby  expressly  waive
and relinquish any right or ability to assert such public policy as a defense to
a claim under this  Section  2.7 and further  agree not to attempt to assert any
such defense.

             2.8 Transfer of Shares After Registration.

                 (a)  Restrictions  on Transfer.  No Holder may make any sale of
any  Restricted  Shares except either (i) in  accordance  with the  Registration
Statement, in which case Holder must comply with the requirement of delivering a
current prospectus,  or (ii) in accordance with Rule 144. Such Restricted Shares
are  not  transferable  on the  books  of the  Company  unless  the  certificate
submitted to the Company's  transfer agent evidencing such Shares is accompanied
by a separate  certificate  executed  by an  officer  of, or other  person  duly
authorized  by, the Holder for  purposes of  establishing  compliance  with this
Agreement.  Such  certificate  shall be in such form as shall be supplied by the
Company.

                 (b) Notice of Proposed Sale; Right of Company to Suspend Use of
Registration  Statement.  If any Holder  shall  propose to sell any  Registrable
Securities  pursuant to the Registration  Statement,  it shall notify Company of
its intent to do so at least  three (3) full  business  days prior to such sale.
Such notice shall be deemed to constitute a representation  that any information
previously supplied by such Holder is accurate as of the date of such notice. At
any time within such three (3) business-day period, Company may refuse to permit
the Holder to resell any  Registrable  Securities  pursuant to the  Registration
Statement;  provided,  however, that the Company in each case shall use its best
reasonable  efforts to respond as rapidly as possible;  and  provided,  however,
that in order to exercise  this right,  Company  must deliver a  certificate  in
writing  to the  Holder to the  effect  that a delay in such  sale is  necessary
because a sale pursuant to such

                                      -10-

                                                                   Page 51 of 59

Registration  Statement  in its  then-current  form  would  not  be in the  best
interests of Company and its  shareholders.  In no event shall such delay exceed
thirty (30) calendar  days with respect to any single  exercise of the Company's
rights hereunder, and provided further,  however, that in no event shall Company
be  permitted  to exercise  this right more than three times or for more than an
aggregate of sixty (60) calendar days in any single  calendar year. In addition,
the  Company  agrees to use its  reasonable  best  efforts to  resolve  whatever
condition or conditions  have  occasioned  any such delay on its part,  and will
promptly end such delay upon resolution of such condition or conditions.

             2.9  Rule  144  Reporting.  With a view  to  making  available  the
benefits of certain rules and  regulations  of the  Commission  which may at any
time  permit  the  sale of the  Registrable  Securities  to the  public  without
registration,  after such time as a public market exists for the Common Stock of
the Company, the Company agrees to:

                 (a) Make and keep public information available,  as those terms
are understood  and defined in Rule 144 under the  Securities  Act, at all times
after the effective  date of the first  registration  under the  Securities  Act
filed by the Company for an offering of its securities to the general public;

                 (b) Use its  best  efforts  to file  with the  Commission  in a
timely manner all reports and other documents  required of the Company under the
Securities Act and the Exchange Act; and

                 (c) So long as a Holder  owns any  Registrable  Securities,  to
furnish to the Holder forthwith upon request a written  statement by the Company
as to its  compliance  with the  reporting  requirements  of Rule 144 and of the
Securities  Act and the  Exchange  Act,  a copy of the  most  recent  annual  or
quarterly  report of the Company,  and such other  reports and  documents of the
Company as a Holder may  reasonably  request in  availing  itself of any rule or
regulation  of the  Commission  allowing  a Holder  to sell any such  securities
without registration.

             2.10  Assignment  of  Registration  Rights.  The rights of a Holder
under  this  Section 2 may be  assigned  by any  Holder in  connection  with any
transfer or assignment by a Holder of Registrable  Securities provided that: (i)
such transfer may otherwise be effected in accordance with applicable securities
laws,  (ii) such transfer is effected in  compliance  with the  restrictions  on
transfer  contained  in the  Agreement  and in any other  agreement  between the
Company  and  the  Holder,  (iii)  such  assignee  or  transferee  either  holds
subsequent to such transfer not less than one hundred thousand  (100,000) shares
of Registrable  Securities (treating the outstanding Series A Preferred Stock on
an  as-converted  basis)  or is a  subsidiary,  wholly-owned  entity,  successor
entity,  parent,  member or stockholder  of a Holder,  and (iv) such other party
agrees in writing with the Company to be bound by all of the  provisions of this
Section 2.

             2.11 Termination of Registration  Rights.  The registration  rights
granted  pursuant to Section 2 will  terminate as to any Holder upon the earlier
to occur of (a) such time as a Holder can sell all of its remaining  Registrable
Securities under Rule 144 of the Securities Act during

                                      -11-

any  three  (3)-month  period,  or (b) such time as all  Registrable  Securities
purchased by such Holder pursuant to the Purchase Agreement have been sold.

         3.  LEGENDS.

             Each Investor  understands that the share  certificates  evidencing
any  Registrable  Securities  shall be endorsed with the  following  legends (in
addition to any legends required under applicable state securities laws):

                 (a)  "THESE  SECURITIES  HAVE NOT  BEEN  REGISTERED  UNDER  THE
SECURITIES  ACT OF 1933,  AS  AMENDED.  THEY MAY NOT BE SOLD,  OFFERED FOR SALE,
PLEDGED OR HYPOTHECATED IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT AS
TO THE SECURITIES  UNDER SAID ACT OR AN OPINION OF COUNSEL  SATISFACTORY  TO THE
CORPORATION THAT SUCH REGISTRATION IS NOT REQUIRED."

                 (b) Any  legend  required  to be  place  thereon  by any  other
applicable state securities laws.

         4.  MISCELLANEOUS.

             4.1 Successors and Assigns.  Except as otherwise expressly provided
herein, the terms and conditions of this Agreement shall inure to the benefit of
and be binding upon the  respective  successors  and permitted  transferees  and
permitted assigns of the parties.

             4.2 Governing Law. This Agreement shall be governed in all respects
by the laws of the State of  California  as applied to contracts  made and to be
performed entirely within that state between residents of that state.

             4.3  Counterparts.  This Agreement may be executed in any number of
counterparts,  each of  which  shall be  deemed  an  original,  and all of which
together shall constitute one instrument.

             4.4  Titles  and  Subtitles.  The  titles  of  the  paragraphs  and
subparagraphs  of this Agreement are used for convenience only and are not to be
considered in construing or interpreting this Agreement.

             4.5 Stock Splits, etc. All share numbers used in this Agreement are
subject to  adjustment  in the case of any stock  split,  reverse  stock  split,

party  pursuant to the  provisions of this Agreement will be in writing and will
be effective and or (i) the date of delivery by facsimile,  or (ii) the business

deposit in the United  States mail by  registered  or certified  mail for United
States deliveries.  All notices not delivered personally or by facsimile will be
sent with postage and other charges prepaid and properly  addressed to the party
to be notified at the address  set forth below such  party's  signature  on this
Agreement or at such other  address as such party may designate by ten (10) days
advance  written  notice to the other parties  hereto.  All notices for delivery
outside the United States will be sent by facsimile, or by nationally recognized
courier or overnight service. Any notice given hereunder to more than one person
will be deemed  to have been  given,  for  purposes  of  counting  time  periods
hereunder, on the date given to the last party required to be given such notice.
Notices to the Company will be marked to the  attention  of the Chief  Financial
Officer.

             4.7 Attorneys' Fees. If any action at law or in equity is necessary
to enforce or interpret the terms of this Agreement,  the prevailing party shall

addition to any other relief to which such party may be entitled.

             4.8  Amendments  and  Waivers.  Any term of this  Agreement  may be

generally   or  in  a   particular   instance   and  either   retroactively   or
prospectively),  only  with  the  written  consent  of the  party  against  whom
enforcement of such amendment or waiver is sought;  provided,  however that with
respect to any  Investor,  the  consent  of the  holders of more than 50% of the
Registrable  Securities  shall be sufficient to bind any and all Investors;  and
provided, further, that where the amendment or waiver affects a right or creates
an obligation  that is specific to a party named herein  (whether an individual,
trust,  partnership  or  corporation),  the amendment or waiver of such right or
creation of such obligation shall require the consent of such party.

             4.9 Severability.  If any provision of this Agreement is held to be
unenforceable  under  applicable law, then such provision shall be excluded from
this Agreement and the balance of the Agreement  shall be interpreted as if such
provision was so excluded and shall be enforceable in accordance with its terms.

             4.10 Entire Agreement.  This Agreement,  together with all Exhibits
hereto,  constitute the full and entire  understanding and agreement between the
parties  with  respect to the subject  matter  hereof and  supersedes  all prior
negotiations,  correspondence, agreements, understandings, duties or obligations
among the parties with respect to the subject matter hereof.

             4.11 Further Assurances. From and after the date of this Agreement,
upon the request of a party,  the other  parties  shall execute and deliver such

purposes of this Agreement.
