         NOW,  THEREFORE,  in  consideration  of the  premises  and  the  mutual

         1.       DEFINITIONS.

                  a. As used in this  Agreement,  the following terms shall have

                      (ii) "register," "registered," and "registration" refer to

                  b.  Capitalized  terms used herein and not  otherwise  defined
herein shall have the respective  meanings set forth in the Securities  Purchase
Agreement.

         2.       REGISTRATION.

                  a. Mandatory Registration.  The Company shall prepare, and, on
or before the  thirtieth  (30th) day  following  the date  hereof  (the  "Filing
Date"), file with the SEC a Registration  Statement on Form S-3 (or, if Form S-3
is not  then  available,  on such  form  of  Registration  Statement  as is then
available to effect a registration of all of the Registrable Securities, subject
to the consent of the Initial Investors (as determined pursuant to Section 11(j)
hereof))  covering  the  resale  of  all  of  the  Registrable  Securities.  The
Registration  Statement  (and each  amendment or  supplement  thereto,  and each
request for  acceleration  of  effectiveness  thereof) shall be provided to (and
subject to the approval of) the Initial Investors and their counsel prior to its
filing or other  submission.  The Initial Investors and their counsel shall have
five (5)  business  days in which to review the  Registration  Statement  and to
provide  comments to the  Company.  If no comments  are  provided by the Initial
Investors  and their  counsel  within such five (5)  business  day  period,  the
Initial Investors shall be deemed to have approved such Registration Statement.

                  b. [Intentionally omitted.]

                  c.  Payments  by the  Company.  The  Company  shall  cause the
Registration  Statement  required to be filed pursuant to Section 2(a) hereof to
become  effective  as  soon as  practicable,  but in no  event  later  than  the
ninetieth  (90th) day following the date hereof (the  "Registration  Deadline").
Notwithstanding the foregoing,  the Registration Deadline shall be extended by a
period of thirty  (30) days in the event the Company  sustains a material  loss,
whether or not insured, by reason of fire, earthquake,  flood, accident or other
calamity. If (i) the Registration  Statement required to be filed by the Company
pursuant  to Section  2(a)  hereof is not  declared  effective  by the SEC on or
before the Registration  Deadline or (ii) if, after such Registration  Statement
has  been  declared  effective  by the  SEC,  sales  of  all of the  Registrable
Securities cannot be made pursuant to such Registration  Statement (by reason of
a stop order or the Company's  failure to update the  Registration  Statement or
any other reason outside the control of the Investors) or (iii) the Common Stock
(including  all of the  Registrable  Securities)  is not listed or included  for
quotation on the Nasdaq  National  Market  ("NNM"),  the Nasdaq  SmallCap Market
("SmallCap"),  the New York Stock  Exchange  (the "NYSE") or the American  Stock
Exchange (the "AMEX") at any time after the  Registration  Deadline and prior to
the  one  (1)  year  anniversary  of the  effective  date  of  the  Registration
Statement, then the Company will make payments to the

                                        2



Investors in such amounts and at such times as shall be  determined  pursuant to
this Section 2(c) as partial  relief for the damages to the  Investors by reason
of any such  delay in or  reduction  of their  ability  to sell the  Registrable
Securities (which remedy shall not be exclusive of any other remedies  available
at law or in equity).  The Company shall pay to each Investor an amount equal to
the  product  of (i) the  aggregate  Purchase  Price of the  Common  Shares  and
Warrants held by such Investor  (including,  without  limitation,  Warrants that
have  been  exercised  for  Warrant  Shares  then  held by such  Investor)  (the
"Aggregate  Share  Price"),  multiplied by (ii) two hundredths  (.02),  for each
thirty (30) day period (or portion thereof) (A) after the Registration  Deadline
and prior to the date the Registration  Statement filed pursuant to Section 2(a)
is declared  effective  by the SEC,  (B) during  which sales of any  Registrable
Securities  cannot be made  pursuant to such  Registration  Statement  after the
Registration   Statement  has  been   declared   effective  and  (C)  after  the
Registration  Deadline and prior to the one (1) year anniversary of the date the
Registration  Statement filed pursuant to Section 2(a) is declared  effective by
the  SEC  during  which  the  Common  Stock  (including  all of the  Registrable
Securities) is not listed or included for quotation on the NNM,  SmallCap,  NYSE
or AMEX; provided,  however,  that there shall be excluded from each such period
any delays which are solely  attributable to changes (other than  corrections of
Company  mistakes  with  respect  to  information  previously  provided  by  the
Investors) required by the Investors in the Registration  Statement with respect
to information relating to the Investors, including, without limitation, changes
to the plan of distribution.  (For example, if the Registration Statement is not
effective by the Registration  Deadline,  the Company would pay $20,000 for each
thirty (30) day period  thereafter  with respect to each $1,000,000 of Aggregate
Share Price until the Registration  Statement  becomes  effective.) Such amounts
shall be paid in cash or, at each  Investor's  option,  may be convertible  into
Common  Stock at the lower of the  Exercise  Price or the Market  Price (each as
defined in the Warrants) in effect at the time of such conversion. Any shares of
Common  Stock  issued  upon  conversion  of such  amounts  shall be  Registrable
Securities.  If the Investor  desires to convert the amounts due hereunder  into
Registrable  Securities it shall so notify the Company in writing within two (2)
business days after the date on which such amounts are first payable in cash and
such amounts  shall be so  convertible  beginning on the last day upon which the
cash amount would  otherwise be due in accordance  with the following  sentence.
Payments of cash  pursuant  hereto  shall be made within five (5) days after the
end of each period that gives rise to such  obligation,  provided  that,  if any
such period  extends for more than thirty (30) days,  interim  payments shall be
made for each such thirty (30) day period.

                  d. [Intentionally omitted.]

                  e.  Eligibility  for Form  S-3.  The  Company  represents  and
warrants that it meets the requirements for the use of Form S-3 for registration
of the sale by the Initial  Investors and any other Investor of the  Registrable
Securities  and the Company  shall file all reports  required to be filed by the
Company with the SEC in a timely manner so as to maintain such  eligibility  for
the use of Form S-3.

                                        3



         3.       OBLIGATIONS OF THE COMPANY.

         In connection with the registration of the Registrable Securities,  the
Company shall have the following obligations:

                  a.  The  Company  shall  prepare  and  file  with  the SEC the
Registration Statement required by Section 2(a) as soon as practicable after the
date  hereof  (but in no event  later  than the  Filing  Date),  and cause  such
Registration Statement relating to Registrable Securities to become effective as
soon  as  practicable  after  such  filing  (but  in no  event  later  than  the
Registration  Deadline),  and keep the Registration Statement effective pursuant
to Rule 415 at all times  until  such date as is the  earlier of (i) the date on
which  all of the  Registrable  Securities  have  been sold and (ii) the date on
which all of the Registrable Securities (in the reasonable opinion of counsel to
the  Initial   Investors)  may  be  immediately   sold  to  the  public  without
registration or restriction  pursuant to Rule 144(k) under the Securities Act or
any  successor  provision  (the  "Registration   Period"),   which  Registration
Statement  (including  any amendments or  supplements  thereto and  prospectuses
contained therein and all documents incorporated by reference therein) shall not
contain any untrue statement of a material fact or omit to state a material fact
required to be stated therein,  or necessary to make the statements  therein not
misleading.

                  b.  The  Company  shall  prepare  and  file  with the SEC such
amendments  (including   post-effective   amendments)  and  supplements  to  the
Registration   Statement  and  the  prospectus   used  in  connection  with  the
Registration  Statement as may be necessary to keep the  Registration  Statement
effective at all times during the Registration  Period, and, during such period,
comply with the provisions of the Securities Act with respect to the disposition
of  all  Registrable  Securities  of the  Company  covered  by the  Registration
Statement  until  such  time as all of such  Registrable  Securities  have  been
disposed of in accordance with the intended methods of disposition by the seller
or sellers thereof as set forth in the Registration Statement.

                  c.  The  Company  shall   furnish  to  each   Investor   whose
Registrable  Securities are included in the Registration Statement and its legal
counsel (i) promptly after the same is prepared and publicly distributed,  filed
with the SEC, or received by the Company, one copy of the Registration Statement
and any amendment thereto,  each preliminary  prospectus and prospectus and each
amendment or supplement thereto,  and each letter written by or on behalf of the
Company to the SEC or the staff of the SEC (including,  without limitation,  any
request  to  accelerate  the  effectiveness  of any  Registration  Statement  or
amendment thereto), and each item of correspondence from the SEC or the staff of
the SEC, in each case relating to such  Registration  Statement  (other than any
portion,  if any,  thereof which contains  information for which the Company has
sought  confidential  treatment),  (ii)  on the  date  of  effectiveness  of the
Registration  Statement  or any  amendment  thereto,  a notice  stating that the
Registration Statement or amendment has been declared effective,  and (iii) such
number of copies of a prospectus,  including a preliminary  prospectus,  and all
amendments and supplements thereto and such other documents as such Investor may
reasonably  request in order to facilitate the  disposition  of the  Registrable
Securities owned by such Investor.

                                        4



                  d. The Company  shall use its best efforts to (i) register and
qualify the Registrable  Securities covered by the Registration  Statement under
such other  securities  or "blue sky" laws of such  jurisdictions  in the United
States  as  each  Investor  who  holds  Registrable   Securities  being  offered
reasonably  requests,   (ii)  prepare  and  file  in  those  jurisdictions  such
amendments  (including  post-effective   amendments)  and  supplements  to  such
registrations   and   qualifications   as  may  be  necessary  to  maintain  the
effectiveness  thereof  during the  Registration  Period,  (iii) take such other
actions as may be necessary to maintain such registrations and qualifications in
effect at all times  during  the  Registration  Period,  and (iv) take all other
actions reasonably necessary or advisable to qualify the Registrable  Securities
for sale in such jurisdictions; provided, however, that the Company shall not be
required in connection  therewith or as a condition thereto to (a) qualify to do
business in any jurisdiction where it would not otherwise be required to qualify
but for this Section 3(d),  (b) subject  itself to general  taxation in any such
jurisdiction,  (c) file a general  consent  to  service  of  process in any such
jurisdiction,  (d) provide any undertakings that cause the Company undue expense
or burden,  or (e) make any change in its charter or bylaws,  which in each case
the Board of  Directors  of the  Company  determines  to be contrary to the best
interests of the Company and its stockholders.

                  e. [Intentionally omitted.]

                  f. As promptly as  practicable  after  becoming  aware of such
event,  the Company shall notify each Investor of the happening of any event, of
which the Company has knowledge, as a result of which the prospectus included in
the Registration Statement, as then in effect, includes an untrue statement of a
material fact or omission to state a material fact required to be stated therein
or necessary to make the  statements  therein not  misleading,  and use its best
efforts  promptly  to prepare a  supplement  or  amendment  to the  Registration
Statement to correct such untrue statement or omission,  and deliver such number
of copies of such  supplement or amendment to each Investor as such Investor may
reasonably request.

                  g. The  Company  shall use its best  efforts  to  prevent  the
issuance  of  any  stop  order  or  other   suspension  of  effectiveness  of  a
Registration  Statement,  and,  if  such an  order  is  issued,  to  obtain  the
withdrawal of such order at the earliest  practicable  moment (including in each
case by amending or  supplementing  such  Registration  Statement) and to notify
each  Investor who holds  Registrable  Securities  being sold of the issuance of
such order and the  resolution  thereof (and if such  Registration  Statement is
supplemented  or amended,  deliver such number of copies of such  supplement  or
amendment to each Investor as such Investor may reasonably request).

                  h.  The  Company   shall  permit  a  single  firm  of  counsel
designated by the Initial Investors to review the Registration Statement and all
amendments and  supplements  thereto a reasonable  period of time prior to their
filing with the SEC,  and not file any  document in a form to which such counsel
reasonably objects and will not request acceleration of the effectiveness of any
Registration Statement without prior notice to such counsel.

                  i. The Company shall make generally  available to its security
holders  as soon as  practical,  but not later than  ninety  (90) days after the
close of the period covered thereby, an


                                        5


earnings  statement (in form complying with the provisions of Rule 158 under the
Securities  Act)  covering a  twelve-month  period  beginning not later than the
first day of the Company's  fiscal  quarter next following the effective date of
the Registration Statement.

                  j.  [Intentionally omitted.]

                  k. The Company shall make  available for inspection by (i) any
Investor and (ii) one firm of  attorneys  and one firm of  accountants  or other
agents retained by the Investors (collectively,  the "Inspectors") all pertinent
financial and other records, and pertinent corporate documents and properties of
the  Company  (collectively,  the  "Records"),  as  shall be  reasonably  deemed
necessary  by each  Inspector  to enable  each  Inspector  to  exercise  its due
diligence  responsibility,  and  cause the  Company's  officers,  directors  and
employees to supply all information  which any Inspector may reasonably  request
for purposes of such due diligence; provided, however, that each Inspector shall
hold in confidence and shall not make any disclosure  (except to an Investor) of
any Record or other information which the Company determines in good faith to be
confidential,  and of which determination the Inspectors are so notified, unless
(a)  the  disclosure  of such  Records  is  necessary  to  avoid  or  correct  a
misstatement or omission in any Registration Statement,  (b) the release of such
Records  is  ordered  pursuant  to a  subpoena  or other  order  from a court or
government  body  of  competent  jurisdiction,  or (c) the  information  in such
Records has been made generally available to the public other than by disclosure
in violation of this or any other  agreement.  The Company shall not be required
to disclose any confidential  information in such Records to any Inspector until
and unless such Inspector shall have entered into confidentiality agreements (in
form and  substance  satisfactory  to the Company) with the Company with respect
thereto,  substantially  in the form of this Section 3(k).  Each Investor agrees
that it shall,  upon learning that disclosure of such Records is sought in or by
a court or governmental  body of competent  jurisdiction or through other means,
give prompt  notice to the Company and allow the  Company,  at its  expense,  to
undertake appropriate action to prevent disclosure of, or to obtain a protective
order for, the Records  deemed  confidential.  Nothing herein shall be deemed to
limit the Investors' ability to sell Registrable Securities in a manner which is
otherwise consistent with applicable laws and regulations.

                  l.  The  Company  shall  hold in  confidence  and not make any
disclosure of information  concerning an Investor provided to the Company unless
(i) disclosure of such  information is necessary to comply with federal or state
securities  laws, (ii) the disclosure of such  information is necessary to avoid
or correct a misstatement or omission in any Registration  Statement,  (iii) the
release of such  information  is ordered  pursuant  to a subpoena or other order
from  a  court  or  governmental  body  of  competent  jurisdiction,  (iv)  such
information  has been made  generally  available  to the  public  other  than by
disclosure  in violation of this or any other  agreement,  or (v) such  Investor
consents to the form and content of any such disclosure. The Company agrees that
it shall,  upon  learning  that  disclosure  of such  information  concerning an
Investor  is  sought  in  or  by a  court  or  governmental  body  of  competent
jurisdiction  or through other means,  give prompt notice to such Investor prior
to making such disclosure,  and allow the Investor, at its expense, to undertake
appropriate  action to prevent  disclosure  of, or to obtain a protective  order
for, such information.

                                        6


                  m. The Company  shall use its best efforts to promptly  either
(i)  cause  all of  the  Registrable  Securities  covered  by  the  Registration
Statement  to be listed on the NYSE or the AMEX or another  national  securities
exchange and on each additional national securities exchange on which securities
of the same class or series  issued by the Company are then  listed,  if any, if
the listing of such Registrable  Securities is then permitted under the rules of
such  exchange,  or (ii)  secure the  designation  and  quotation  of all of the
Registrable  Securities  covered  by the  Registration  Statement  on the NNM or
SmallCap and, without  limiting the generality of the foregoing,  to arrange for
or maintain at least two market makers to register with the National Association
of Securities  Dealers,  Inc.  ("NASD") as such with respect to such Registrable
Securities.

                  n. Chase Mellon Shareholder  Services,  LLC (or any substitute
transfer agent and registrar  selected by the Company) shall act as the transfer
agent and registrar for the Registrable Securities.

                  o. The Company  shall  cooperate  with the  Investors who hold
Registrable  Securities  being offered to facilitate the timely  preparation and
delivery of  certificates  (not bearing any  restrictive  legends)  representing
Registrable  Securities to be offered pursuant to the Registration Statement and
enable such certificates to be in such denominations or amounts, as the case may
be, as the Investors may reasonably  request and registered in such names as the
Investors may request,  and, within three (3) business days after a Registration
Statement which includes Registrable Securities is ordered effective by the SEC,
the Company shall deliver, and shall cause legal counsel selected by the Company
to deliver, to the transfer agent for the Registrable Securities (with copies to
the Investors  whose  Registrable  Securities are included in such  Registration
Statement) an opinion of such counsel in the form attached hereto as Exhibit 1.

                  p. At the request of any  Investor  (which shall be limited to
two (2)  requests),  the  Company  shall  prepare  and  file  with  the SEC such
amendments  (including   post-effective   amendments)  and  supplements  to  the
Registration   Statement  and  the  prospectus   used  in  connection  with  the
Registration  Statement  as may be  necessary  in  order to  change  the plan of
distribution set forth in such Registration Statement.

                  q. The Company shall comply with all  applicable  laws related
to the  Registration  Statement  and  offering  and sale of  securities  and all
applicable  rules and  regulations  of  governmental  authorities  in connection
therewith (including,  without limitation, the Securities Act and the Securities
Exchange Act of 1934, as amended,  and the rules and regulations  promulgated by
the SEC.)

                  r.  The  Company  shall  take all such  other  actions  as any
Investor  reasonably requests in order to expedite or facilitate the disposition
of the Registrable Securities.

                  s.  From and  after the date of this  Agreement,  the  Company
shall not,  and shall not agree to, allow the holders of any  securities  of the
Company to include any of their securities in any  Registration  Statement under
Section 2(a) hereof or any  amendment or  supplement  thereto under Section 3(b)
hereof without the consent of the holders of a majority in interest of the


                                        7


Registrable Securities;  provided,  however, that the Company shall be permitted
to include in any such  Registration  Statement  (including  any  amendments  or
supplements  thereto)  any shares of Common  Stock  issuable by the Company upon
exercise of or  otherwise  pursuant to those  certain  stock  purchase  warrants
issued to each of Wharton  Capital  Partners  Ltd.  and  Elizabeth  D'Angelis on
February 27, 1998.

         All  obligations  of the Company under this Section 3 (except for those
obligations  set forth in paragraph  (l) of this  Section 3) shall  terminate as
soon as the Investors no longer own any Registrable Securities.

         4.       OBLIGATIONS OF THE INVESTORS.

         In connection with the registration of the Registrable Securities,  the
Investors shall have the following obligations:

                  a. It shall be a condition precedent to the obligations of the
Company to complete the registration  pursuant to this Agreement with respect to
the  Registrable  Securities of a particular  Investor that such Investor  shall
furnish to the  Company  such  information  regarding  itself,  the  Registrable
Securities  held by it and the intended method of disposition of the Registrable
Securities held by it as shall be reasonably required to effect the registration
of such  Registrable  Securities  and shall execute such documents in connection
with such registration as the Company may reasonably  request. At least five (5)
business  days prior to the first  anticipated  filing date of the  Registration
Statement, the Company shall notify each Investor of the information the Company
requires from each such Investor.

                  b.  Each  Investor,  by  such  Investor's  acceptance  of  the
Registrable  Securities,  agrees to  cooperate  with the  Company as  reasonably
requested by the Company in connection  with the  preparation  and filing of the
Registration Statement hereunder,  unless such Investor has notified the Company
in  writing  of such  Investor's  election  to  exclude  all of such  Investor's
Registrable Securities from the Registration Statement.

                  c. [Intentionally omitted.]

                  d. Each Investor  agrees that, upon receipt of any notice from
the Company of the happening of any event of the kind described in Sections 3(f)
or 3(g), such Investor will immediately  discontinue  disposition of Registrable
Securities  pursuant to the  Registration  Statement  covering such  Registrable
Securities  until such Investor's  receipt of the copies of the  supplemented or
amended prospectus  contemplated by Sections 3(f) or 3(g) and, if so directed by
the Company,  such Investor  shall deliver to the Company (at the expense of the
Company) or destroy (and deliver to the Company a  certificate  of  destruction)
all  copies in such  Investor's  possession,  of the  prospectus  covering  such
Registrable Securities current at the time of receipt of such notice.

                  e. [Intentionally omitted.]


                                        8



         5.       EXPENSES OF REGISTRATION.

         All  reasonable  expenses  incurred in connection  with  registrations,
filings or  qualifications  pursuant  to  Sections 2 and 4,  including,  without
limitation,  all registration,  listing and  qualifications  fees,  printers and
accounting  fees, the fees and  disbursements of counsel for the Company and the
fees and disbursements contemplated by Section 3(k) hereof shall be borne by the
Company.  In addition,  the Company  shall pay all of the  Investors'  costs and
expenses  (including  legal fees) incurred in connection with the enforcement of
the rights of the Investors hereunder.

         6.       INDEMNIFICATION.

         In the event any Registrable  Securities are included in a Registration
Statement under this Agreement:

                  a. To the extent permitted by law, the Company will indemnify,
hold  harmless  and  defend  (i)  each  Investor  who  holds  such   Registrable
Securities,  and (ii) the directors,  officers,  partners,  members,  employees,
agents and each person who controls  any Investor  within the meaning of Section
15 of the Securities  Act or Section 20 of the Securities  Exchange Act of 1934,
as amended (the  "Exchange  Act"),  if any,  (each,  an  "Indemnified  Person"),
against any joint or several losses,  claims,  damages,  liabilities or expenses
(collectively, together with actions, proceedings or inquiries by any regulatory
or  self-regulatory  organization,  whether commenced or threatened,  in respect
thereof,  "Claims")  to which any of them may  become  subject  insofar  as such
Claims  arise out of or are based  upon:  (i) any  untrue  statement  or alleged
untrue statement of a material fact in a Registration  Statement or the omission
or alleged  omission to state  therein a material  fact required to be stated or
necessary  to make the  statements  therein  not  misleading,  (ii)  any  untrue
statement  or alleged  untrue  statement  of a material  fact  contained  in any
preliminary  prospectus if used prior to the effective date of such Registration
Statement, or contained in the final prospectus (as amended or supplemented,  if
the Company files any amendment  thereof or supplement  thereto with the SEC) or
the omission or alleged omission to state therein any material fact necessary to
make the statements made therein,  in light of the circumstances under which the
statements therein were made, not misleading,  or (iii) any violation or alleged
violation by the Company of the  Securities  Act,  the  Exchange  Act, any other
applicable securities law, including,  without limitation,  any state securities
law, or any rule or regulation  thereunder  relating to the offer or sale of the
Registrable  Securities (the matters in the foregoing  clauses (i) through (iii)
being,  collectively,  "Violations").  Subject to the  restrictions set forth in
Section  6(c) with  respect to the number of legal  counsel,  the Company  shall
reimburse  the  Investors and each other  Indemnified  Person,  promptly as such
expenses are incurred and are due and payable,  for any reasonable legal fees or
other reasonable  expenses incurred by them in connection with  investigating or
defending  any such Claim.  Notwithstanding  anything to the contrary  contained
herein, the indemnification  agreement contained in this Section 6(a): (i) shall
not apply to a Claim  arising out of or based upon a Violation  which  occurs in
reliance upon and in  conformity  with  information  furnished in writing to the
Company  by  such  Indemnified  Person  expressly  for  use in the  Registration
Statement or any such amendment  thereof or supplement  thereto;  (ii) shall not
apply to amounts paid in settlement of any Claim if such  settlement is effected
without the prior written consent of the Company, which


                                        9


consent  shall not be  unreasonably  withheld;  and (iii)  with  respect  to any
preliminary prospectus, shall not inure to the benefit of any Indemnified Person
if  the  untrue  statement  or  omission  of  material  fact  contained  in  the
preliminary  prospectus  was corrected on a timely basis in the  prospectus,  as
then  amended or  supplemented,  if such  corrected  prospectus  was timely made
available by the Company  pursuant to Section 3(c) hereof,  and the  Indemnified
Person was promptly advised in writing not to use the incorrect prospectus prior
to  the  use  giving  rise  to  a  Violation   and  such   Indemnified   Person,
notwithstanding  such advice, used it. Such indemnity shall remain in full force
and  effect  regardless  of  any  investigation  made  by or on  behalf  of  the
Indemnified Person and shall survive the transfer of the Registrable  Securities
by the Investors pursuant to Section 9 hereof.

                  b. In connection with any  Registration  Statement in which an
Investor is  participating,  each such Investor agrees severally and not jointly
to  indemnify,  hold  harmless  and  defend,  to the same extent and in the same
manner set forth in Section 6(a), the Company,  each of its  directors,  each of
its officers who signs the  Registration  Statement,  its employees,  agents and
each person,  if any, who controls the Company  within the meaning of Section 15
of the  Securities  Act or  Section  20 of  the  Exchange  Act,  and  any  other
stockholder selling securities pursuant to the Registration  Statement or any of
its directors or officers or any person who controls such stockholder within the
meaning of the  Securities  Act or the Exchange Act  (collectively  and together
with an Indemnified Person, an "Indemnified Party"),  against any Claim to which
any of them may become  subject,  under the Securities  Act, the Exchange Act or
otherwise,  insofar as such Claim arises out of or is based upon any  Violation,
in each case to the extent (and only to the extent) that such  Violation  occurs
in reliance upon and in  conformity  with written  information  furnished to the
Company by such Investor  expressly for use in connection with such Registration
Statement; and subject to Section 6(c) such Investor will reimburse any legal or
other expenses  (promptly as such expenses are incurred and are due and payable)
reasonably  incurred by them in connection with  investigating  or defending any
such Claim;  provided,  however,  that the indemnity agreement contained in this
Section 6(b) shall not apply to amounts paid in  settlement of any Claim if such
settlement is effected without the prior written consent of such Investor, which
consent shall not be unreasonably withheld; provided, further, however, that the
Investor shall be liable under this Agreement  (including  this Section 6(b) and
Section 7) for only that  amount as does not exceed  the net  proceeds  actually
received  by such  Investor  as a result of the sale of  Registrable  Securities
pursuant to such  Registration  Statement.  Such indemnity  shall remain in full
force and effect  regardless of any  investigation  made by or on behalf of such
Indemnified  Party and shall survive the transfer of the Registrable  Securities
by the Investors pursuant to Section 9 hereof.  Notwithstanding  anything to the
contrary  contained  herein,  the  indemnification  agreement  contained in this
Section 6(b) with respect to any preliminary  prospectus  shall not inure to the
benefit of any Indemnified Party if the untrue statement or omission of material
fact contained in the preliminary  prospectus was corrected on a timely basis in
the  prospectus,  as then amended or  supplemented,  and the  Indemnified  Party
failed to utilize such corrected prospectus.

                  c.  Promptly  after  receipt  by  an  Indemnified   Person  or
Indemnified  Party  under this  Section 6 of notice of the  commencement  of any
action  (including  any  governmental   action),   such  Indemnified  Person  or
Indemnified  Party shall,  if a Claim in respect  thereof is to made against any
indemnifying  party under this  Section 6, deliver to the  indemnifying  party a
written notice of


                                       10


the commencement  thereof,  and the  indemnifying  party shall have the right to
participate in, and, to the extent the  indemnifying  party so desires,  jointly
with any other indemnifying  party similarly  noticed,  to assume control of the
defense thereof with counsel mutually satisfactory to the indemnifying party and
the Indemnified  Person or the Indemnified  Party, as the case may be; provided,
however,  that such  indemnifying  party  shall not be  entitled  to assume such
defense and an Indemnified  Person or Indemnified  Party shall have the right to
retain its own counsel with the fees and expenses to be paid by the indemnifying
party,  if, in the reasonable  opinion of counsel  retained by the  indemnifying
party,  the  representation  by  such  counsel  of  the  Indemnified  Person  or
Indemnified  Party and the  indemnifying  party  would be  inappropriate  due to
actual or potential  conflicts of interest  between such  Indemnified  Person or
Indemnified  Party and any  other  party  represented  by such  counsel  in such
proceeding  or the actual or  potential  defendants  in, or targets of, any such
action  include both the  Indemnified  Person or the  Indemnified  Party and the
indemnifying  party  and  any  such  Indemnified  Person  or  Indemnified  Party
reasonably  determines  that  there  may be  legal  defenses  available  to such
Indemnified  Person or Indemnified Party which are different from or in addition
to those available to such indemnifying  party. The indemnifying party shall pay
for  only  one  separate  legal  counsel  for  the  Indemnified  Persons  or the
Indemnified Parties, as applicable,  and such legal counsel shall be selected by
Investors holding a majority-in-interest  of the Registrable Securities included
in the  Registration  Statement to which the Claim relates (with the approval of
the  Initial  Investors  if they hold  Registrable  Securities  included in such
Registration  Statement),  if the  Investors  are  entitled  to  indemnification
hereunder,  or by the  Company,  if the Company is  entitled to  indemnification
hereunder,  as  applicable.  The  failure  to  deliver  written  notice  to  the
indemnifying  party within a  reasonable  time of the  commencement  of any such
action  shall  not  relieve  such  indemnifying  party of any  liability  to the
Indemnified  Person or  Indemnified  Party  under this  Section 6, except to the
extent  that the  indemnifying  party is actually  prejudiced  in its ability to
defend such action. The indemnification required by this Section 6 shall be made
by  periodic   payments  of  the  amount   thereof  during  the  course  of  the
investigation or defense, as such expense, loss, damage or liability is incurred
and is due and payable.

         7.       CONTRIBUTION.

         To  the  extent  any   indemnification  by  an  indemnifying  party  is
prohibited or limited by law, the indemnifying  party agrees to make the maximum
contribution  with respect to any amounts for which it would otherwise be liable
under Section 6 to the fullest extent permitted by law; provided,  however, that
(i) no contribution shall be made under  circumstances where the maker would not
have been  liable for  indemnification  under the fault  standards  set forth in
Section 6, (ii) no person  guilty of  fraudulent  misrepresentation  (within the
meaning  of  Section  11(f)  of  the  Securities   Act)  shall  be  entitled  to
contribution  from any seller of  Registrable  Securities  who was not guilty of
such fraudulent  misrepresentation,  and (iii)  contribution  (together with any
indemnification  or other  obligations  under this  Agreement)  by any seller of
Registrable  Securities shall be limited in amount to the net amount of proceeds
received by such seller from the sale of such Registrable Securities.



                                       11



         8.       REPORTS UNDER THE EXCHANGE ACT.

         With a view to making  available to the  Investors the benefits of Rule
144 promulgated under the Securities Act or any other similar rule or regulation
of the SEC that may at any time permit the  Investors to sell  securities of the
Company to the public without registration ("Rule 144"), the Company agrees to:

                  a.  file  with  the SEC in a timely  manner  and make and keep
available  all reports  and other  documents  required of the Company  under the
Securities  Act and the Exchange Act so long as the Company  remains  subject to
such  requirements  (it being  understood  that  nothing  herein shall limit the
Company's  obligations under Section 4(c) of the Securities  Purchase Agreement)
and the filing and  availability of such reports and other documents is required
for the applicable provisions of Rule 144; and

                  b.  furnish to each  Investor  so long as such  Investor  owns
Warrants  or  Registrable  Securities,  promptly  upon  request,  (i) a  written
statement by the Company that it has complied with the reporting requirements of
Rule 144,  the  Securities  Act and the  Exchange  Act,  (ii) a copy of the most
recent  annual or  quarterly  report of the Company  and such other  reports and
documents so filed by the Company,  and (iii) such other  information  as may be
reasonably  requested to permit the Investors to sell such securities under Rule
144 without registration.

         The  obligations  of the  Company  set  forth in this  Section  8 shall
terminate  as  soon as the  Investors  may  resell  the  Registrable  Securities
pursuant to Rule 144(k).

         9.       ASSIGNMENT OF REGISTRATION RIGHTS.

         The rights of the Investors hereunder,  including the right to have the
Company register  Registrable  Securities  pursuant to this Agreement,  shall be
automatically  assignable  by  each  Investor  to any  transferee  of all or any
portion of the Common Shares, the Warrants or the Registrable Securities if: (i)
the Investor  agrees in writing with the  transferee  or assignee to assign such
rights,  and a copy of such  agreement is  furnished  to the Company  after such
assignment,  (ii) the Company is furnished  with written  notice of (a) the name
and address of such transferee or assignee,  and (b) the securities with respect
to which such  registration  rights are being  transferred  or  assigned,  (iii)
following  such  transfer  or  assignment,   the  further  disposition  of  such
securities by the transferee or assignee is restricted  under the Securities Act
and applicable  state securities laws, (iv) the transferee or assignee agrees in
writing  for the  benefit of the  Company  to be bound by all of the  provisions
contained herein,  and (v) such transfer shall have been made in accordance with
the applicable requirements of the Securities Purchase Agreement.

         10.      AMENDMENT OF REGISTRATION RIGHTS.

         Provisions of this Agreement may be amended and the observance  thereof
may  be  waived  (either  generally  or  in a  particular  instance  and  either
retroactively  or  prospectively),  only with written consent of the Company and
Investors who hold a majority in interest of the Registrable


                                       12



Securities;  provided,  however,  that  no  consideration  shall  be  paid to an
Investor by the  Company in  connection  with an  amendment  hereto  unless each
Investor  similarly  affected by such  amendment  receives a pro-rata  amount of
consideration  from the  Company.  Unless an  Investor  otherwise  agrees,  each
amendment  hereto must similarly  affect each Investor.  Any amendment or waiver
effected in accordance  with this Section 10 shall be binding upon each Investor
and the Company.

         11.      MISCELLANEOUS.

                  a. A person or entity is deemed to be a holder of  Registrable
Securities  whenever  such  person or entity  owns of  record  such  Registrable
Securities.  If  the  Company  receives  conflicting  instructions,  notices  or
elections  from  two or more  persons  or  entities  with  respect  to the  same
Registrable  Securities,  the Company shall act upon the basis of  instructions,
notice  or  election  received  from the  registered  owner of such  Registrable
Securities.

                  b. Any  notices  required or  permitted  to be given under the
terms of this  Agreement  shall be sent by certified or registered  mail (return
receipt  requested)  or  delivered  personally  or by  courier  or by  confirmed
telecopy,  and shall be effective  five (5) days after being placed in the mail,
if mailed, or upon receipt or refusal of receipt, if delivered  personally or by
courier or confirmed telecopy,  in each case addressed to a party. The addresses

                  c.  Failure of any party to exercise any right or remedy under
this  Agreement or otherwise,  or delay by a party in  exercising  such right or
remedy, shall not operate as a waiver thereof.


                                       13



                  d.  This  Agreement  shall be  governed  by and  construed  in
accordance  with the laws of the State of Delaware  applicable to contracts made
and to be performed in the State of Delaware.  The Company irrevocably  consents
to the  jurisdiction  of the United States  federal  courts and the state courts
located in the State of Delaware in any suit or  proceeding  based on or arising
under this Agreement and  irrevocably  agrees that all claims in respect of such
suit or proceeding  may be determined  in such courts.  The Company  irrevocably
waives the defense of an  inconvenient  forum to the maintenance of such suit or
proceeding. The Company further agrees that service of process upon the Company,
mailed by first class mail shall be deemed in every respect effective service of
process upon the Company in any such suit or  proceeding.  Nothing  herein shall
affect the  Investors'  right to serve process in any other manner  permitted by
law. The Company agrees that a final non-appealable judgment in any such suit or
proceeding  shall be conclusive  and may be enforced in other  jurisdictions  by
suit on such judgment or in any other lawful manner.

                  e.  This   Agreement,   the  Securities   Purchase   Agreement
(including all schedules and exhibits  thereto) and the Warrants  constitute the
entire  agreement  among the parties  hereto with respect to the subject  matter
hereof and thereof.  This Agreement,  the Securities  Purchase Agreement and the
Warrants  supersede all prior  agreements and  understandings  among the parties
hereto with respect to the subject matter hereof and thereof.

                  f.  Subject  to the  requirements  of  Section 9 hereof,  this
Agreement  shall inure to the benefit of and be binding upon the  successors and
assigns of each of the parties hereto.

                  g. The  headings  in this  Agreement  are for  convenience  of
reference only and shall not limit or otherwise affect the meaning hereof.

                  h. This Agreement may be executed in two or more counterparts,
each of which shall be deemed an original but all of which shall  constitute one
and the same  agreement.  This  Agreement,  once  executed  by a  party,  may be
delivered to the other party hereto by facsimile  transmission of a copy of this
Agreement bearing the signature of the party so delivering this Agreement.

                  i. Each party  shall do and  perform,  or cause to be done and
performed,  all such further acts and things,  and shall execute and deliver all
such other  agreements,  certificates,  instruments and documents,  as the other
party may reasonably request in order to carry out the intent and accomplish the
purposes of this Agreement and the consummation of the transactions contemplated
hereby.

                  j. All consents, approvals and other determinations to be made
by the Investors or the Initial  Investors  pursuant to this Agreement  shall be
made by the Investors or the Initial Investors holding a majority in interest of
the Registrable  Securities  (determined as if all Warrants then outstanding had
been  exercised  for  Registrable  Securities)  held by all Investors or Initial
Investors, as the case may be.

                  RE: FOCUS ENHANCEMENTS, INC.

Ladies and Gentlemen:

         We are counsel to FOCUS  ENHANCEMENTS,  INC., a  corporation  organized
under the laws of the State of Delaware (the "Company"),  and we understand that
[Name of Investor]  (the  "Holder") has purchased from the Company (i) shares of
the Company's  common stock,  par value $______ per share (the "Common  Stock"),
and (ii) warrants (the  "Warrants") to acquire shares of Common Stock.  Pursuant
to a Registration Rights Agreement,  dated as of February 27, 1998, by and among
the Company and the signatories  thereto (the "Registration  Rights Agreement"),
the Company  agreed  with the  Holder,  among  other  things,  to  register  the
Registrable  Securities  (as that term is  defined  in the  Registration  Rights
Agreement) under the Securities Act of 1933, as amended (the "Securities  Act"),
upon the terms provided in the Registration Rights Agreement. In connection with
the  Company's   obligations  under  the  Registration   Rights  Agreement,   on
__________, 1998, the Company filed a Registration Statement on Form S-___ (File
No. 333- _____________)  (the "Registration  Statement") with the Securities and
Exchange  Commission (the "SEC") relating to the Registrable  Securities,  which
names the Holder as a selling stockholder thereunder. The Registration Statement
was declared effective by the SEC on _____________, 1998.

         [Other customary  introductory and scope of examination  language to be
inserted]

         Based on the  foregoing,  we are of the  opinion  that the  Registrable
Securities have been registered under the Securities Act.

                                    [Other customary language to be included.]

                                            Very truly yours,



cc:   [Name of Investor]
