         2. Required Registration Under the Securities Act.

         (a) The Company  shall,  for the benefit of the holders of  Registrable
Securities,  at the Company's  cost, file with the Commission on or prior to the
later of (i) ninety (90) days after the initial closing of the private placement
in which the Units are sold in accordance with the Memorandum (the "Closing") or
(ii) March 31, 1996, a Shelf  Registration  Statement  providing for the sale by
the holders of all the Registrable Securities, and shall use its best efforts to
have such Shelf  Registration  Statement declared effective by the Commission as
soon as practicable and, in any event,  within 60 days  thereafter.  The Company
agrees  to use  its  best  efforts  to keep  the  Shelf  Registration  Statement
continuously   effective  for  a  period  of  three  years  after  the  date  of
effectiveness  (the  "Effectiveness  Period").  The Company shall not permit any
securities  other  than  Registrable  Securities  to be  included  in the  Shelf
Registration,  except for up to 250,000  shares of Common Stock held by the Bank
Lenders (as such term is defined in the  Memorandum) and up to 363,636 shares of
Common Stock held by Active  Investors II, Ltd. The Company further  agrees,  if
necessary or appropriate, to supplement or

                                        3







amend the Shelf Registration Statement, if required by the rules, regulations or
instructions  applicable to the  registration  form used by the Company for such
Shelf Registration  Statement or by the Securities Act or by any other rules and
regulations  thereunder  for  shelf  registrations,  and the  Company  agrees to
furnish to the holders of Registrable  Securities  copies of any such supplement
or amendment promptly after its being used or filed with the Commission.

         (b) Effective  Registration  Statement.  A Shelf Registration Statement
pursuant  to  Section  2(a) above  will not be deemed to have  become  effective
unless it has been declared effective by the Commission; provided that if, after
it has been declared effective,  the offering of Registrable Securities pursuant
to a  Shelf  Registration  Statement  is  interfered  with  by any  stop  order,
injunction  or  other  order  or  requirement  of the  Commission  or any  other
governmental agency or court, such Registration  Statement will be deemed not to
have been effective during the period of such  interference,  until the offering
of Registrable  Securities  pursuant to such Registration  Statement may legally
resume.  The Company will be deemed not to have used its  reasonable  efforts to
cause the Shelf Registration Statement to become, or to remain, effective during
the requisite period if it voluntarily takes any action that would result in any
such Registration Statement not being effective or in the holders of Registrable
Securities  covered  thereby  not being able to offer and sell such  Registrable
Securities during that period.

         (c)  Additional  Interest.  In  the  event  that  either  (i)  a  Shelf
Registration Statement is not filed with the Commission on or prior to the later
of the 90th day after the Closing or March 31, 1996 (the "Filing Date"), or (ii)
a Shelf Registration Statement is not declared effective on or prior to the 60th
day after  the  Filing  Date,  the  interest  rate  borne by the Notes  shall be
increased  (the  "Additional  Interest")  by one  percent  per  annum  from  and
including  the 91st day after the  Closing  in the case of clause  (i) above and
from and including the 61st day after the Filing Date in the case of clause (ii)
above and shall  increase by an additional one percent per annum for each 90-day
period (or portion  thereof) that any  Additional  Interest  continues to accrue
pursuant to this Section  2(c);  provided  that the  aggregate  increase in such
interest  rate  pursuant to this  Section  2(c) will in no event  (other than as
stated in the  succeeding  proviso)  exceed  five  percent  (5%) per annum,  and
provided,  further,  that the interest rate shall  increase to eighteen  percent
(18%) in the event the Shelf Registration Statement is not effective nine months
after the Closing. Upon (x) the filing of a Shelf Registration  Statement in the
case of  clause  (i)  above  or (y) the  effectiveness  of a Shelf  Registration
Statement  in the case of  clause  (ii)  above,  and  provided  that none of the
conditions  set forth in  clauses  (i) or (ii)  above  continues  to exist,  the
interest rate borne by the Notes from the date of such filing or  effectiveness,
as the case may be, will be reduced to the original interest rate.

         In the event that the Shelf  Registration  Statement  has been declared
effective  and  subsequently  ceases  to be  effective  prior  to the end of the
Effectiveness  Period,  for a  period  in  excess  of 10  days,  whether  or not
consecutive, in any given year, then, the interest rate borne by the Notes shall
be  increased  by an  additional  one  percent  per annum on the 11th day in the
applicable  year such Shelf  Registration  Statement  ceases to be effective and
thereafter  by an additional  one percent per annum for each  additional 90 days
that such Shelf  Registration  Statement is not  effective,  subject to the same
provisions with respect to the increase in the

                                        4







interest  rate  referred to above;  provided that the interest rate borne by the
Notes will not be increased if the Registrable  Securities are otherwise  freely
tradeable  pursuant to Rule 144 under the Securities Act. Upon the effectiveness
of a Shelf Registration Statement, the interest rate borne by the Notes shall be
reduced to their original  interest rate unless and until increased as described
in this paragraph.

         The Company shall notify Commonwealth  Associates within three business
days  after  each and every  date on which an event  occurs in  respect of which
Additional  Interest is required to be paid (an "Event  Date").  The  Additional
Interest due shall be payable on each interest payment date to the record holder
of Notes entitled to receive the interest payment to be paid on such date as set
forth in the Notes.  Each obligation to pay Additional  Interest shall be deemed
to accrue from and including the day following the applicable Event Date.

         (d) Specific  Enforcement.  Without limiting the remedies  available to
the holders of Registrable Securities, the Company acknowledges that any failure
by the  Company to comply with its  obligations  under  Section  2(a) hereof may
result in  material  irreparable  injury to such  holders  for which there is no
adequate  remedy at law,  that it would not be possible  to measure  damages for
such injuries  precisely  and that,  in the event of any such failure,  any such
holder of  Registrable  Securities  may obtain such relief as may be required to
specifically enforce the Company's obligations under Section 2(a) hereof.

         3. Piggyback Registration Rights.

         (a) Right to Piggyback.  Whenever the Company  proposes to register any
Shares (or  securities  convertible  into or  exchangeable  or  exercisable  for
Shares) under the Securities Act, at any time on or before the Expiration  Date,
for its own  account  or for the  account  of other  Persons  exercising  demand
registration  rights  other than (i) pursuant to Section 4 below or (ii) under a
Registration  Statement  on Form S-4,  Form S-8 or any  successor  form filed in
connection  with an exchange  offer or an offering of  securities  solely to the
Company's existing  employees or security holders (a "Piggyback  Registration"),
the  Company  will give  prompt  written  notice to all  holders of  Registrable
Securities of its intention to effect such a Registration  and will use its best
efforts,   subject  to  Section  3(b)  below,   to  include  in  such  Piggyback
Registration  all  Registrable  Securities with respect to which the Company has
received  written  requests for inclusion  therein within thirty (30) days after
the receipt of the Company's notice. Except as may otherwise be provided in this
Agreement,  Registrable  Securities  with  respect  to which  such  request  for
Registration  has been received will be registered by the Company and offered to
the public on the same terms and subject to the same  conditions  applicable  to
the  Piggyback  Registration  to be sold by the Company or by the other  Persons
selling under such Piggyback Registration.

         (b) Priority on Piggyback  Registrations.  If a Piggyback  Registration
relates to an underwritten offering and the managing underwriter or underwriters
advise  the  Company  in  writing  that in its or their  opinion  the  number of
securities  proposed to be sold in a Piggyback  Registration  exceeds the number
which can be sold in such offering within a price

                                        5







range  acceptable  to  the  Company  or  the  other  Persons  exercising  demand
registration rights, the Company will include in such Piggyback Registration the
number of securities  which, in the opinion of such underwriter or underwriters,
can be sold within such price  range,  which  securities  shall be  allocated as
follows:  (w)  first,  the  securities  proposed  to be  sold by  other  Persons
exercising  demand  registration  rights granted on or prior to the date hereof,
(x) second,  so long as the Senior  Indebtedness  (as defined in the Memorandum)
remains  outstanding,  up to an aggregate of 250,000 shares of Common Stock held
by the Bank Lenders,  provided,  that such priority shall be effective for up to
only two such  Piggyback  Registration  opportunities,  (y)  third,  Registrable
Securities  held by the Holder and  requested  to be included in such  Piggyback
Registration,  together  with any other  securities  requested to be included in
such Piggyback  Registration by other holders, pro rata among the Holder and the
other  holders  of  Registrable  Securities  (on  the  basis  of the  amount  of
Registrable  Securities then owned by each such holder) requested to be included
in such  Piggyback  Registration,  and (z) fourth,  the  securities  the Company
proposes to sell.

         (c)  Underwriting.  If a Piggyback  Registration  for which the Company
gives notice is for a registered public offering involving an underwriting,  the
Company shall so advise the Holder in the notice given pursuant to Section 3(a),
which notice shall include the name of the managing underwriter or underwriters.

         4. Demand Registration Rights.

         (a) Right to Demand.  At any time on or before the Expiration Date, the
holders  of  not  less  than  a  majority  of the  Registrable  Securities  then
outstanding  may make up to two  written  requests  (provided  in each case such
holders have not registered  Registrable  Securities  pursuant to Section 2 or 3
above  within 120 days prior to such  request) to the  Company for  registration
with  the  Commission  under  and  in  accordance  with  the  provisions  of the
Securities  Act of not less  than  $250,000  of the  Registrable  Securities  (a
"Demand Registration").  Within ten (10) days after receipt of such request, the
Company shall give written  notice of such requested  registration  to all other
holders of Registrable  Securities,  and, subject to the priority provisions set
forth in Section 4(b) below,  will include in such  registration all Registrable
Securities with respect to which the Company has received  written  requests for
inclusion  within thirty (30) days after the Company  gives such notice.  Unless
expressly agreed to by the Holder,  no securities of the Company or of any other
Person  other  than  Registrable  Securities  shall  be  included  in  a  Demand
Registration  except  pursuant  to the  exercise of any  piggyback  registration
rights  granted on or prior to the date  hereof.  Except as  otherwise  provided
herein,  a  registration  will not count as a Demand  Registration  until it has
become effective and the holders of the Registrable  Securities included in such
registration are legally permitted to sell all of their  Registrable  Securities
that  are  requested  to  be so  included  unless  the  holders  of  Registrable
Securities included in such Demand Registration fail to take such actions as are
required on their part to cause the registration to become  effective,  in which
case such registration shall count as a Demand Registration.

                                        6







         (b) Priority on Demand  Registrations.  If the managing  underwriter or
underwriters of a Demand  Registration advise the Company in writing that in its
or their  opinion  the number of  securities  proposed to be sold in such Demand
Registration exceeds the number which can be sold in such offering,  the Company
will include in such Demand Registration only the number of securities which, in
the opinion of such  underwriter or  underwriters,  can be sold in such offering
which  securities  shall be allocated on a pro rata basis among the  Registrable
Securities  and such other  securities  requested  to be included in such Demand
Registration  pursuant to the  exercise  of any  piggyback  registration  rights
granted on or prior to the date hereof.

         (c)  Selection  of  Underwriters.  If  any  Demand  Registration  is an
underwritten  offering,  a majority in  interest  of the  Holders  will select a
managing  underwriter or  underwriters to administer the offering which managing
underwriter or underwriters shall be of nationally recognized standing and shall
be reasonably acceptable to the Company; provided,  however, that the holders of
Registrable Securities  acknowledge that Commonwealth  Associates has a right of
first refusal to act as  underwriter  in connection  with any offering of Common
Stock if the terms offered by  Commonwealth  Associates  are comparable to those
being offered by other investment banking firms to similarly-situated companies,
and hereby  consent to the use of  Commonwealth  Associates  as  underwriter  in
connection with any Demand Registration.

         5. Registration  Procedures.  With respect to any Registration pursuant
to the exercise of rights provided by Sections 2, 3 and 4 of this Agreement, the
Company will (subject to Sections 2(a) and 12 hereof) promptly:

          (a) prepare and file with the Commission a  Registration  Statement (a
     "Registration Statement") which includes the Registrable Securities and use
     its best efforts to cause such  Registration  Statement to become effective
     as promptly as  practicable;  provided  that before  filing a  Registration
     Statement or any  amendments  thereto or any  Prospectus,  the Company will
     furnish  to one  counsel  selected  by the  holders  of a  majority  of the
     Registrable  Securities to be included and the underwriters,  if any, draft
     copies  of all such  documents  proposed  to be  filed  at  least  five (5)
     business  days  prior  thereto,  which  documents  will be  subject  to the
     reasonable  review of such counsel and  underwriters,  and the Company will
     not file any Registration  Statement or amendment thereto or any Prospectus
     to which a majority of such holders shall reasonably  object (provided that
     nothing herein shall prevent the Company from making a timely filing of any
     report required to be filed by it pursuant to the Exchange Act in such form
     as it determines is appropriate) and will notify the holders of Registrable
     Securities  of any stop order issued or  threatened  by the  Commission  in
     connection  therewith and take all reasonable  actions  required to prevent
     the entry of such stop order or to remove it if entered;

          (b)  prepare  and  file  with  the  Commission   such  amendments  and
     post-effective amendments to the Registration Statement as may be necessary
     to keep the Registration  Statement effective for a period of not less than
     four (4) months (or such  shorter  period  which  will  terminate  when all
     Registrable  Securities  covered by such  Registration  Statement have been
     sold or withdrawn, but not prior to the expiration of any applicable period
     referred to in Section

                                        7







     4(3) of the Securities Act and Rule 174 thereunder,  if applicable, or such
     longer period pursuant to Section 2(a) hereof);  cause the Prospectus to be
     supplemented by any required Prospectus supplement,  and as so supplemented
     to be filed pursuant to Rule 424 under the Securities  Act; and comply with
     the  provisions of the  Securities Act applicable to it with respect to the
     disposition of all securities covered by such Registration Statement during
     the  applicable   period  in  accordance  with  the  intended   methods  of
     disposition by the sellers thereof set forth in such Registration Statement
     or Prospectus supplement;

          (c)  furnish  to  each  seller  of  Registrable   Securities  and  the
     underwriter  or  underwriters,  if any,  at least  one  signed  copy of the
     Registration  Statement  and any  post-effective  amendment  thereto,  upon
     request,  and such number of  conformed  copies  thereof and such number of
     copies of the Prospectus (including each preliminary  Prospectus),  and any
     documents  incorporated by reference therein, as such seller or underwriter
     may  reasonably  request  in order to  facilitate  the  disposition  of the
     Registrable  Securities being sold by such seller (it being understood that
     the Company  consents to the use of the  Prospectus  by such seller and the
     underwriter or  underwriters,  if any, in connection  with the offering and
     sale of the Registrable Securities covered by the Prospectus);

          (d) notify each seller of  Registrable  Securities  at any time when a
     Prospectus  relating to Registrable  Securities is required to be delivered
     under the Securities  Act, when the Company  becomes aware of the happening
     of any  event  as a  result  of  which  the  Prospectus  included  in  such
     Registration Statement (as then in effect) contains any untrue statement of
     a material  fact or omits to state a material  fact  necessary  to make the
     statements  therein  (in the  case  of the  Prospectus  or any  preliminary
     Prospectus,  in light of the circumstances  under which they were made) not
     misleading  and, as promptly as  practicable  thereafter,  prepare and file
     with the  Commission  and make  available a supplement or amendment to such
     Prospectus  so that,  as  thereafter  delivered to the  purchasers  of such
     Registrable  Securities,  such  Prospectus  will  not  contain  any  untrue
     statement of a material fact or omit to state a material fact  necessary to
     make the statements therein, in light of the circumstances under which they
     were made, not misleading;

          (e) use its best  efforts to cause all  Registrable  Securities  to be
     listed,  by the date such  Registrable  Securities  cease to be Registrable
     Securities as a result of  Registration  or otherwise,  on each  securities
     exchange or national  quotation  system on which the Shares are then listed
     or proposed to be listed, if any;

          (f) make  generally  available  to its  security  holders an  earnings
     statement  satisfying the provisions of Section 11(a) of the Securities Act
     no later than 45 days after the end of the 12-month  period  beginning with
     the first day of the Company's  first fiscal quarter  commencing  after the
     effective date of the  Registration  Statement,  which  earnings  statement
     shall cover said 12-month period; provided, however, that in the event that
     the first day of the Company's  first fiscal quarter  commencing  after the
     effective date of the Registration Statement shall also be the first day of
     the Company's fiscal year, such earnings  statement shall be made generally
     available no later than 90 days after the end of such 12-month period;

                                        8








          (g) use its  best  efforts  to  obtain  the  withdrawal  of any  order
     suspending the effectiveness of the Registration  Statement at the earliest
     possible moment;

          (h) if requested by the managing  underwriter or  underwriters  or any
     holder of  Registrable  Securities,  promptly  incorporate  in a Prospectus
     supplement or  post-effective  amendment  such  information as the managing
     underwriter or underwriters or such holder requests to be included  therein
     with  respect to the number of  Registrable  Securities  being sold by such
     holder to such underwriter or  underwriters,  the purchase price being paid
     therefor by such  underwriter or underwriters and with respect to any other
     terms of the underwritten offering of the Registrable Securities to be sold
     in such offering; and promptly make all required filings of such Prospectus
     supplement or post-effective amendment;

     deliver a copy of such document to each holder of Registrable Securities;

          (j) on or prior to the date on which  the  Registration  Statement  is
     declared  effective,  use its best  efforts to  register  or  qualify,  and
     cooperate with the holders of a majority of the Registrable Securities, the
     underwriter or underwriters,  if any, and their counsel, in connection with
     the registration or qualification of the Registrable  Securities covered by
     the Registration  Statement for offer and sale under the securities or blue
     sky laws of each state and other  jurisdiction  of the  United  States as a
     majority of the such holders or underwriter reasonably requests in writing,
     to use its best  efforts to keep each such  registration  or  qualification
     effective, including through new filings, or amendments or renewals, during
     the period such  Registration  Statement  is required to be kept  effective
     pursuant to Section  5(b) hereof and to do any and all other acts or things
     necessary or advisable to permit the disposition in all such  jurisdictions
     of  the  Registrable  Securities  covered  by the  applicable  Registration
     Statement;

          (k)  cooperate  with the  holders of  Registrable  Securities  and the
     managing  underwriter  or  underwriters,  if any, to facilitate  the timely
     preparation  and  delivery of  certificates  (not  bearing any  restrictive
     legends)  representing   Registrable   Securities  to  be  sold  under  the
     Registration   Statement   and  enable  such   securities  to  be  in  such
     denominations  and registered in such names as the managing  underwriter or
     underwriters, if any, or any such holder may request;

          (l) use its best efforts to cause the Registrable  Securities  covered
     by the  Registration  Statement to be  registered  with or approved by such
     other governmental  agencies or authorities within the United States as may
     be  necessary  to enable  such  holder  of  Registrable  Securities  or the
     underwriter or underwriters,  if any, to consummate the disposition of such
     Registrable Securities;

          (m) enter into such customary  agreements  (including an  underwriting
     agreement in customary form) and take all such other actions as the holders
     of a majority of the Registrable

                                        9







     Securities being sold or the underwriters retained by such holders, if any,
     reasonably  request in order to expedite or facilitate  the  disposition of
     such Registrable Securities;

          (n) make available for inspection by a  representative  of the sellers
     of Registrable Securities, any underwriter participating in any disposition
     pursuant to such Registration  Statement,  and any attorney,  accountant or
     other agent retained by any such seller or underwriter  (collectively,  the
     "Inspectors"),   all  financial  and  other  records,  pertinent  corporate
     documents  and  properties  of the  Company  and its  direct  and  indirect
     subsidiaries (collectively, the "Records") as shall be reasonably necessary
     to enable them to exercise  their due diligence  reasonably,  and cause the
     Company's  officers,  directors  and  employees  to supply all  information
     reasonably  requested  by any  such  Inspectors  in  connection  with  such
     Registration  Statement;  provided  that  the  Records  which  the  Company
     determines,  in good faith,  to be  confidential  and which it notifies the
     Inspectors are confidential shall not be disclosed to the Inspectors unless
     (x) the  disclosure  of such  Records  is  necessary  to avoid or correct a
     misstatement or omission in the  Registration  Statement or (y) the release
     of such  Records is ordered  pursuant  to a subpoena  or other order from a
     court of competent jurisdiction;  provided,  however, that any decision not
     to  disclose  information  pursuant  to  clause  (x)  shall  be made  after
     consultation with counsel for the Company,  and such  representative of the
     sellers agrees that it will,  upon learning that disclosure of such Records
     is sought in a court of competent jurisdiction,  give notice to the Company
     and allow the Company, at the Company's expense,  to undertake  appropriate
     action to prevent disclosure of the Records deemed confidential;

          (o) use its best  efforts  to obtain a cold  comfort  letter  from the
     Company's  independent  public  accountants  in customary form and covering
     such matters of the type  customarily  covered by cold comfort letters as a
     representative of the sellers of Registrable Securities reasonably request;
     and

          (p) furnish each seller of Registrable  Securities  with an opinion of
     its counsel  (reasonably  acceptable to such seller) to the effect that (i)
     such  registration  statement has become effective under the Securities Act
     and no order suspending the effectiveness of such  registration  statement,
     preventing  or  suspending  the use of  such  registration  statement,  any
     preliminary  prospectus,   any  final  prospectus,   or  any  amendment  or
     supplement  thereto  has  been  issued,  nor  has  the  SEC  instituted  or
     threatened to institute any proceedings with respect to such an order, (ii)
     such  registration  statement  and each  prospectus  forming a part thereof
     (including each  preliminary  prospectus),  and any amendment or supplement
     thereto,  complies  as to form  with the  Securities  Act and the rules and
     regulations  thereunder,  and (iii) such  counsel has no  knowledge  of any
     material  misstatement  or omission in such  registration  statement or any
     prospectus,  as amended or supplemented except no opinion need be expressed
     as to the financial statements and related schedules,  and counsel shall be
     entitled to rely on opinions of other counsel  reasonably  satisfactory  to
     such sellers regarding matters of foreign law and intellectual property.

                                       10







         The  Holder,  upon  receipt  of any  notice  from  the  Company  of the
happening of any event of the kind  described in Section  5(d),  will  forthwith
discontinue disposition of the Registrable Securities until the Holder's receipt
of the copies of the supplemented or amended Prospectus  contemplated by Section
5(d) or until it is advised in writing  (the  "Advice")  by the Company that the
use of the Prospectus may be resumed,  and has received copies of any additional
or supplemental  filings which are  incorporated by reference in the Prospectus,
and,  if so  directed  by the  Company,  the Holder  will,  or will  request the
managing  underwriter  or  underwriters,  if any,  to deliver to the Company all
copies, other than permanent file copies then in the Holder's possession, of the
Prospectus  covering such Registrable  Securities at the time of receipt of such
notice.  In the event the Company  shall give any such  notice,  the time period
mentioned  in Section  5(b) shall be  extended  by the number of  business  days
during the period  from and  including  the date of the giving of such notice to
and  including  the date when the Holder  shall have  received the copies of the
supplemented or amended Prospectus contemplated by Section 5(d) or the Advice.

         The Holder shall furnish to the Company such information  regarding the
Registrable Securities held by it and the intended method of disposition thereof
and other  information  concerning  the Holder as the Company  shall  reasonably
request and as shall be required in connection with the  Registration  Statement
to be filed by the Company.

         6. Holdback Arrangements.

         (a) Restrictions on Public Sale by Holder of Registrable Securities. To
the extent not inconsistent with applicable law, the Holder agrees not to effect
any public sale or distribution of the securities  being registered or a similar
security of the Company,  or any securities  convertible into or exchangeable or
exercisable for such  securities,  including a sale pursuant to Rule 144 or Rule
144A  under the  Securities  Act,  during and not  exceeding  180 days after the
effective  date  of  a  Registration   Statement  relating  to  an  underwritten
Registration of Registrable  Securities,  as may be reasonably  requested by the
managing  underwriter  or  underwriters,  except  as part  of such  Registration
Statement.

         (b) Restrictions on Public Sale by the Company.  The Company agrees (x)
not to effect any public sale or distribution of any securities similar to those
being  registered,  or  any  securities  convertible  into  or  exchangeable  or
exercisable  for such  securities  (other than any such sale or  distribution of
such  securities in connection  with any merger or  consolidation  involving the
Company  or a  subsidiary  thereof  or  the  acquisition  by  the  Company  or a
subsidiary  thereof of the capital equity or substantially  all of the assets of
any other Person or with respect to any employee benefit or stock plan),  during
the fourteen  (14) days prior to, and during such period not  exceeding 180 days
after the effective date of any  Registration  Statement  except as part of such
Registration  Statement;  and (y) that any agreement entered into after the date
of this  Agreement  pursuant to which the Company  issues or agrees to issue any
privately  placed  securities  shall contain a provision  under which holders of
such securities  agree not to effect any public sale or distribution of any such
securities  during the period  described in (x) above,  in each case including a
sale pursuant to Rule 144 or Rule 144A under the Securities Act (except

                                       11







as part of any such registration,  if permitted);  provided,  however,  that the
provision of this Section 6(b) shall not prevent the  conversion  or exchange of
any securities pursuant to their terms as in effect prior to the commencement of
such period into or for other securities.

         (c)  Other  Registrations.  If  the  Company  has  previously  filed  a
Registration  Statement  with  respect to  Registrable  Securities,  and if such
previous registration has not been withdrawn or abandoned,  the Company will not
file or cause to be effective  any other  registration  of any of the Shares (or
securities convertible into or exchangeable or exercisable for the Shares) under
the Securities Act (except on Form S-4 or S-8 or any successor forms or filed in
connection  with an exchange  offer or an offering of  securities  solely to the
Company's existing employees or security holders),  whether on its own or at the
request of any holder or holders of the Shares (or securities  convertible  into
or exchangeable  or exercisable for the Shares),  until a period of at least 120
days has elapsed from the effective date of such previous registration (provided
that in the case of a Demand Registration such period shall commence on the date
the Company is first served the notice of demand registration and shall continue
until at least 180 days have  elapsed  from the  effective  date of such  Demand
Registration).

         7. Indemnification; Contribution.

         (a) Indemnification by the Company. The Company agrees to indemnify and
hold harmless each holder of  Registrable  Securities  and each of such holder's
officers, directors and agents and each Person, if any, who controls a holder of
Registrable Securities within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act (each, an "Indemnitee")  from and against any and
all losses,  claims,  damages,  liabilities and expenses  (including  reasonable
attorneys'  fees and costs of  investigation)  arising  out of or based upon any
untrue statement or alleged untrue statement of a material fact contained in any
Registration  Statement  or  Prospectus,  or  arising  out of or based  upon any
omission or alleged  omission to state  therein a material  fact  required to be
stated  therein or  necessary  to make the  statements  therein not  misleading,
except insofar as such losses,  claims,  damages,  liabilities or expenses arise
out of or are based upon information  with respect to such Indemnitee  furnished
in writing to the Company by such  Indemnitee  expressly for use therein.  It is
agreed that the  indemnification  agreement contained in this Section 7(a) shall
not apply to  amounts  paid in  settlement  of any such loss,  claim,  damage or
liability  if such  settlement  is  effected  without the consent of the Company
(which consent has not been unreasonably  withheld).  The Company also agrees to
indemnify  any  underwriters  on  substantially  the  same  basis as that of the
indemnification  of the  holders  of  Registrable  Securities  provided  in this
Section 7(a).

                                       12







         (b) Conduct of Indemnification Proceedings. If any action or proceeding
(including any governmental  investigation) shall be brought or asserted against
the holders of Registrable Securities (or its officers,  directors or agents) or
any Person  controlling  any such  holder in respect of which  indemnity  may be
sought from the Company, the Company shall be permitted to assume the defense of
such claim,  unless in the reasonable  judgment of such Indemnitee a conflict of
interest may exist between such  Indemnitee and the Company with respect to such
claim or differing or additional  defenses may be available to such  Indemnitee.
If defense of a claim is assumed by the Company, Indemnitees shall not be liable
for any  settlement of such action or proceedings  effected  without their prior
written consent.  The Company will not consent to entry of any judgment or enter
into any settlement which does not include as an unconditional  term thereof the
giving by the  claimant or plaintiff  to such  Indemnitee  of a release from all
liability in respect of such claim or litigation. If the Company is not entitled
to, or elects not to, assume the defense of a claim, it will not be obligated to
pay the fees and  expenses  of more than one counsel  for the  Indemnitees  as a
group  with  respect  to such  claim  in each  jurisdiction  in which a claim is
brought,  unless in the  reasonable  judgment  of any  Indemnitee  a conflict of
interest may exist between such Indemnitee and any other Indemnitee with respect
to such claim or  differing  or  additional  defenses  may be  available to such
Indemnitee,  in which event the Company  shall be  obligated to pay the fees and
expenses  of such  additional  counsel.  Each holder of  Registrable  Securities
agrees to give prompt  written  notice to the  Company  after its receipt of any
written  notice  of  the  commencement  of  any  action,  suit,  proceedings  or
investigation  or threat thereof made in writing for which such holder may claim
indemnification or contribution pursuant to this Agreement;  provided,  however,
that  failure  to give such  notice  shall not limit the  Indemnitee's  right to
indemnification  or  contribution  hereunder  unless and to the extent  that the
Company did not otherwise  learn of such action and such failure  results in the
forfeiture by it of substantial rights and defenses.

         (c)  Indemnification  by  the  Holders.   Each  holder  of  Registrable
Securities agrees to indemnify and hold harmless the Company, and its directors,
officers and agents and each Person, if any, who controls the Company within the
meaning of either Section 15 of the Securities Act or Section 20 of the Exchange
Act to the same  extent as the  foregoing  indemnity  from the  Company  to such
holder but only with respect to information  furnished in writing by such holder
with respect to such holder which  contained a material  misstatement of fact or
omission of a material fact expressly for use in any  Registration  Statement or
any amendment thereto or any Prospectus,  or any preliminary Prospectus relating
to the Registrable Securities. In case any action or proceeding shall be brought
against  the  Company,  each  holder of  Registrable  Securities  or any of such
holder's  respective  directors,  officers  or agents,  or any such  controlling
Person,  in respect of which  indemnity may be sought against such holder,  such
holder shall have the rights and duties  given to the Company,  and the Company,
or its directors,  officers or agents or such controlling Person, shall have the
rights and duties given to such holder by Section 7(b).

                                       13







         (d) Contribution. If the indemnification provided for in this Section 7
is  unavailable  to the Company,  the holders of  Registrable  Securities or the
underwriters in respect to any losses, claims, damages, liabilities or judgments
referred to herein,  then each such indemnifying  party, in lieu of indemnifying
such indemnified  party,  shall contribute to the amount paid or payable by such
indemnified party as a result of such losses, claims,  damages,  liabilities and
judgments in such  proportion as is appropriate to reflect the relative fault of
the  indemnifying  parties  and  indemnified  parties  in  connection  with such
statements  or  omissions  which  resulted  in  the  losses,  claims,   damages,
liabilities   or   judgments,   as  well  as  any   other   relevant   equitable
considerations.  The relative fault of such  indemnifying  party and indemnified
parties shall be  determined  by reference  to, among other things,  whether the
untrue or alleged untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by such party,
and  the  parties'  relative  intent,  knowledge,   access  to  information  and
opportunity to correct or prevent such statement or omission.

         The  Company and the holders of  Registrable  Securities  agree that it
would not be just and  equitable if  contribution  pursuant to this Section 7(d)
were  determined  by pro rata  allocation  or by any other method of  allocation
which does not take account of the equitable  considerations  referred to in the
immediately  preceding  paragraph.  The amount paid or payable by an indemnified
party as a result of the  losses,  claims,  damages,  liabilities  or  judgments
referred to in the immediately  preceding  paragraph shall be deemed to include,
subject  to the  limitation  set  forth  above,  any  legal  or  other  expenses
reasonably  incurred by such indemnified party in connection with  investigating
or  defending  any  such  action  or  claim.  No  Person  guilty  of  fraudulent
misrepresentations  (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  misrepresentations.  For the  purposes of this  Section  7(d),  each
director of the Company, each officer who signed the Registration  Statement and
each Person,  if any, who controls the Company  within the meaning of Section 15
of the Securities Act shall have the same rights to contribution as the Company.

         8.   Participation   in  Underwritten   Registrations.   No  holder  of
Registrable   Securities  may  participate  in  any  underwritten   Registration
hereunder (which shall be conducted in accordance with the provisions of Section
2, 3 or 4) unless  such  holder  (i)  agrees to sell such  holder's  Registrable
Securities  on the basis  provided in any  customary  underwriting  arrangements
(approved by the holders of Registrable  Securities as provided herein) and (ii)
completes  and executes  all  questionnaires,  powers of attorney,  underwriting
agreements  and  other  documents  reasonably  required  under the terms of such
underwriting arrangements and these registration rights; provided, however, such
holder shall not be required to make  representations  or give  indemnifications
except  with  respect  to  information  provided  in  writing  by the  holder of
Registrable Securities concerning such holder and its plan of distribution.

                                       14







         9. Rule  144.  The  Company  covenants  that it will  file any  reports
required to be filed by it under the Securities Act and the Exchange Act and the
rules and regulations  adopted by the Commission  thereunder (or, if the Company
is not required to file such reports,  it will,  upon the request of the holders
of Registrable Securities,  make publicly available other information so long as
necessary to permit sales under Rule 144 under the Securities Act), that it will
take such further action as the holders of Registrable Securities may reasonably
request,  all to the extent required from time to time to enable such holders to
sell Registrable Securities without registration under the Securities Act within
the limitations of the exemptions  provided by (i) Rule 144 under the Securities
Act, as such rule may be amended from time to time,  or (ii) any similar rule or
regulation hereafter adopted by the Commission.  Upon the request of the holders
of  Registrable  Securities,  the  Company  will  deliver to each such  holder a
written  statement as to whether it has complied with the  requirements  of this
Section 9.

         10.  Registration  Expenses.  The Registration  Expenses related to the
Shelf  Registration,  first Demand  Registration and any Piggyback  Registration
shall be borne solely by the Company.

         11. Stand-Off and Special Audit.

         (a) Stand-Off.  If at the time of any request for a Demand Registration
pursuant  to Section 4, the Company (i) is engaged or has fixed plans to engage,
within  thirty  (30) days of the time of the  request,  in a  registered  public
offering  as to which the holders of  Registrable  Securities  may,  pursuant to
Section 4, include all Registrable  Securities  proposed to be sold by them, and
which in fact becomes  effective  within 90 days after the  request,  or (ii) is
engaged in any other  activity  which,  in the good faith  determination  of the
Company's  board  of  directors,  would  be  adversely  affected  by the  Demand
Registration to the material  detriment of the Company,  then the Company may at
its option  direct  that such  request be delayed for a period not to exceed six
(6) months from the effective date of such offering or the date of  commencement
of such other material  activity,  as the case may be, provided that each holder
of Registrable Securities has had no other request delayed during the six months
prior to such request.

         (b) Provisions for Special Audit.  In the event that a special audit of
the Company's  financial  statements  would be required to effect a Registration
pursuant  to  Section  4, the  Company  shall  promptly  notify  each  holder of
Registrable  Securities  that a special audit is required.  In such event,  such
holders   shall  have  the  right  to  either  (i)  withdraw  such  request  for
Registration, in which case the request shall not count as a Demand Registration
to which such holders are entitled under this Agreement or (ii) pay the expenses
of conducting the special audit.

         12.  Public  Trading  Market.  Until the earlier of (a) three (3) years
after  the  date  hereof  or (b) the  date on  which  there  are no  Registrable
Securities,  the Company shall use its best efforts to maintain a public trading
market for its Shares.

                                       15







         13. Representations and Warranties of the Company.

         (a) The  execution,  delivery and  performance of this Agreement by the
Company have been duly authorized by all requisite corporate action and will not
violate  any  provision  of law,  any  order of any  court or  other  agency  of
government, the Restated Certificate of Incorporation or By-laws of the Company,
or any provision of any indenture,  agreement or other instrument to which it or
any of its properties or assets is bound,  or conflict with,  result in a breach
of or constitute  (with due notice or lapse of time or both) a default under any
such  indenture,  agreement  or other  instrument,  or result in the creation or
imposition of any lien,  charge or encumbrance of any nature whatsoever upon any
of the properties or assets of the Company.

         (b) This Agreement has been duly executed, and delivered by the Company
and  constitutes  the  legal,  valid  and  binding  obligation  of the  Company,
enforceable in accordance with its terms.

         14. Miscellaneous.

         (a) Other  Registration  Rights.  Except as provided in the Memorandum,
the Company does not have and shall not grant  registration  rights with respect
to any  securities  of the Company to any Person that are  superior  to, or that
adversely affect, the registration  rights granted to the holders of Registrable
Securities  pursuant to this  Agreement.  The  Company  shall not enter into any
agreement inconsistent with any of the provisions hereof.

         (b)  Amendments.  This Agreement may not be amended without the written
consent of the Company and a majority of the holders of Registrable Securities.

         (c) Successors and Assigns. The Company may not sell, assign,  transfer
or  otherwise  convey any of its rights or delegate any of its duties under this
Agreement,  except to a corporation  which has succeeded to substantially all of
the  business  and  assets  of the  Company  and  has  assumed  in  writing  its
obligations  under this  Agreement,  and this Agreement  shall be binding on the
Company and such  successor.  This Agreement  shall be binding upon and inure to
the benefit of and be  enforceable by the Holder and its successors and assigns.
Without limiting the generality of the foregoing,  any transferee of Registrable
Securities  shall have the rights set forth in this  Agreement,  and such rights
shall be  enforceable  against the Company by such  transferees  as  third-party
beneficiaries.

         (d)  Notices.  All  notices  and  other  communications   provided  for
hereunder shall be given and shall be effective as provided in the Warrant.

         (e)  Descriptive  Headings.  The  headings  in this  Agreement  are for
convenience  of  reference  only and  shall not limit or  otherwise  affect  the
meaning of terms contained herein.

                                       16







         (f) Severability.  In the event that any one or more of the provisions,
paragraphs,  words,  clauses,  phrases or  sentences  contained  herein,  or the
application  thereof  in  any  circumstances,   is  held  invalid,   illegal  or
unenforceable  in any  respect  for  any  reason,  the  validity,  legality  and
enforceability of such provision, paragraph, word, clause, phrase or sentence in
every other respect and of the remaining provisions, paragraphs, words, clauses,
phrases or sentences hereof shall not be in any way impaired,  it being intended
that  all  rights,  powers  and  privileges  of  the  parties  hereto  shall  be
enforceable to the fullest extent permitted by law.

         (g)  Counterparts.  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 instrument,  and it shall not be necessary in making
proof  of  this  Agreement  to  produce  or  account  for  more  than  one  such
counterpart.

Registrable  Securities in any way pursuant to Section 2(d) hereof,  the Company

shall be the  surviving  corporation  of such  merger or  consolidation  and, in
connection  with such merger or  consolidation,  all or part of the  Registrable
Securities  shall be changed into or exchanged for stock or other  securities of

that such Person shall be bound by the provisions of this Agreement and the term
