       2. REGISTRATION PROCEDURES.

          (a) The Company  shall  prepare  and, on or prior to 30 days after the
initial  issuance  date of the  Preferred Stock,  file with the  Commission  a
Registration  Statement on Form S-3 (or, if such form is unavailable  for such a
registration,  on such  other  form as is  available  for  such a  registration,
subject to the consent of each Investor,  which consent will not be unreasonably
withheld),   covering  the  resale  of  all  of  the  Restricted  Stock,   which
Registration  Statement  shall state that, in accordance with Rule 416 under the
Securities  Act,  such  Registration  Statement  also covers such  indeterminate
number of additional shares of Common Stock as may become issuable upon exercise
of the Warrants to prevent dilution resulting from

                                       2

<PAGE>

stock  splits,  stock  dividends  or  similar  transactions.   The  Registration
Statement  shall  initially  register for resale that number of shares of Common
Stock equal to the number of shares of Restricted  Stock issuable as of the date
immediately  preceding the date the  Registration  Statement is initially  filed
with the  Commission  as if such  date of  registration  was a date on which the
Preferred  Stock was  converted  and the  Warrants  were  exercised,  subject to
adjustment as provided therein.  Such registered shares of Common Stock shall be
allocated  among the  Investors  pro rata based on the total number of shares of
Restricted  Stock  issued  or  issuable  as of  each  date  that a  Registration
Statement,  as  amended,  relating  to the  resale  of the  Restricted  Stock is
declared effective by the Commission.

          (b) In connection with the Registration Statement, the Company shall:

          (i) use its best  efforts to cause the  Registration  Statement  to be
declared  effective  within  90 days  after  the  initial  issuance  date of the
Preferred  Stock  and to remain  effective  for the  period of the  distribution
contemplated thereby (determined as hereinafter provided);

          (ii)  prepare  and  file  with  the  Commission  such  amendments  and
supplements to the Registration  Statement and the prospectus used in connection
therewith as may be necessary to keep the  Registration  Statement  continuously
effective,  pursuant to Rule 415, for the period specified in paragraph 2(c) and
comply with the provisions of the Securities Act with respect to the disposition
of all Restricted Stock covered by the Registration Statement in accordance with
the  sellers'  intended  method of  disposition  set  forth in the  Registration
Statement  for such period;  PROVIDED,  HOWEVER,  notwithstanding  the foregoing
provisions  of this  Section  2(b)(ii),  the  Company may suspend the use of the
Registration  Statement  for a period  not to  exceed  45 days  (whether  or not
consecutive)  in any  12-month  period if the Board of  Directors of the Company
determines in good faith that because of valid  business  reasons (that would be
required to be disclosed in an amendment to the prospectus),  including  pending
mergers or other business combination  transactions,  the planned acquisition or
divestiture  of assets,  pending  material  corporate  developments  and similar
events,  it is in the best  interests  of the Company to suspend  such use,  and
prior to or contemporaneously  with suspending such use the Company provides the
Investors with written notice of such suspension,  which notice need not specify
the nature of the event giving rise to such  suspension;  at the end of any such
suspension  period,  the Company shall provide the Investors with written notice
of the termination of such suspension;

          (iii)  permit each  Investor  and a single firm of counsel,  initially
Schulte  Roth & Zabel LLP or such other  counsel  as  thereafter  designated  as
selling  stockholders'  counsel  by the  Investors  who hold a  majority  of the
Restricted  Stock  being  sold,  to review  and  comment  upon the  Registration
Statement(s)  and all  amendments  and  supplements  thereto at least three days
prior to their filing with the  Commission,  and not file any document in a form
to which such counsel reasonably objects; the Company shall not submit a request
for  acceleration  of the  effectiveness  of a Registration  Statement(s) or any
amendment or  supplement  thereto  without the prior  approval of such  counsel,
which  consent  shall not be  unreasonably  withheld;  the Company  shall not be
required to make any payments  under  Section 2(g) if the delay in declaring the
Registration Statement effective is due to such counsel's unreasonable objection
to the form of any such  document or its  withholding  approval of the Company's
acceleration request;

                                       3

<PAGE>

          (iv)  furnish  to  each  seller  of  Restricted   Stock  and  to  each
underwriter  (to the extent that a majority of the holders of  Restricted  Stock
elect to use an underwriter or to the extent of an underwritten  public offering
as contemplated  by Section 2A below) such number of copies of the  Registration
Statement  and the  prospectus  included  therein  (including  each  preliminary
prospectus)  as such persons  reasonably  may request in order to facilitate the
public  sale  or  other  disposition  of the  Restricted  Stock  covered  by the
Registration Statement;

          (v) use its best efforts to register or qualify the  Restricted  Stock
covered by the Registration Statement under the securities or "blue sky" laws of
such  jurisdictions  as the  sellers of  Restricted  Stock or, in the case of an
underwritten  public  offering,  the  managing  underwriter,   reasonably  shall
request;  PROVIDED,  HOWEVER, that the Company shall not for any such purpose be
required to qualify generally to transact  business as a foreign  corporation in
any  jurisdiction  where it is not so qualified or to consent to general service
of process in any such jurisdiction;

          (vi)  immediately  notify each seller of the Restricted Stock and each
underwriter  (to the extent that a majority of the holders of  Restricted  Stock
elect to use an underwriter or to the extent of an underwritten  public offering
as contemplated by Section 2A below) under the  Registration  Statement,  at any
time when a prospectus  relating  thereto is required to be delivered  under the
Securities Act, of the happening of any event of which the Company has knowledge
and as a result of which the prospectus contained in the Registration Statement,
as then in effect,  includes an untrue  statement of a material fact or omits to
state a material  fact  required to be stated  therein or  necessary to make the
statements  therein not misleading in light of the circumstances  then existing;
and

          (vii) make  available  for  inspection  by each  seller of  Restricted
Stock,  any  underwriter  (to the  extent  that a  majority  of the  holders  of
Restricted Stock elect to use an underwriter or to the extent of an underwritten
public  offering  as  contemplated  by  Section 2A below)  participating  in any
distribution  pursuant  to  the  Registration   Statement,   and  any  attorney,
accountant or other agent retained by such seller or underwriter,  all financial
and other records,  pertinent corporate documents and properties of the Company,
and cause  the  Company's  officers,  directors  and  employees  to  supply  all
information  reasonably  requested  by any such seller,  underwriter,  attorney,
accountant or agent in connection with the Registration Statement.

          (c) For  purposes  of  subsections  2(b)(i)  and (ii),  the  period of
distribution  of  Restricted  Stock  in a firm  commitment  underwritten  public
offering  shall be deemed to extend until each  underwriter  has  completed  the
distribution  of all securities  purchased by it, and the period of distribution
of Restricted  Stock in any other  registration  shall be deemed to extend until
pursuant  to Rule 415 at all times until the earlier of (i) the date as of which
the Investors may sell all of the Restricted Stock without restriction  pursuant
to Rule 144(k) promulgated under the Securities Act (or successor thereto), (ii)
the date on which (x) the Investors shall have sold all the Restricted Stock and
(y) none of the  Warrants is  outstanding,  or (iii) the date which is two years
after the Warrants have been exercised in full.

          (d) Each seller of Restricted  Stock agrees that,  upon receipt of any
notice from the Company of the  happening of any event of the kind  described in
subsection  2(b)(ii),  such seller will immediately  discontinue  disposition of
Restricted  Securities  pursuant to the

                                       4
<PAGE>

prospectus included in the Registration Statement until such seller's receipt of
the copies of the supplemented or amended prospectus  contemplated by subsection
2(b)(ii),  and, if so directed by the  Company,  such seller will deliver to the
Company  all copies,  other than  permanent  file  copies then in such  seller's
possession, of the most recent prospectus covering such Restricted Securities at
the time of receipt of such notice.  If the Company shall give such notice,  the
Company shall extend the period during which the Registration Statement shall be
maintained  effective by the number of days during the period from and including
the date of the giving of notice  pursuant  to  subsection  2(b)(ii) to the date
when the Company shall make  available to such seller a prospectus  supplemented
or amended to conform with the requirements of subsection 2(b)(ii).

          (e) In connection  with each  registration  hereunder,  the sellers of
Restricted  Stock will furnish to the Company in writing such  information  with
respect to themselves and the proposed distribution by them, as reasonably shall
be necessary and reasonably  requested by the Company's  counsel in writing,  in
order to assure compliance with federal and applicable state securities laws.

          (f) In the event the public  offering of the Restricted  Securities is
underwritten,  the  Company  and  each  seller  agree to  enter  into a  written
agreement with the managing  underwriter selected by the Company and approved by
the holders of a majority of the Restricted  Stock  (assuming  conversion of the
outstanding  Preferred Stock and exercise of the outstanding  Warrants as of the
date  the  Company   requests  such  consent),   which  approval  shall  not  be
unreasonably withheld or delayed, in such form and containing such provisions as
are customary in the securities  business for such an  arrangement  between such
underwriter and companies of the Company's size and investment stature.

          (g) The Company understands that a breach of the Company's obligations
under  Sections 2(a) and 2(b)(i) could result in economic loss to the Investors.
As  compensation  to the  Investors  for such loss (and not as a  penalty),  the
Company agrees to pay to the Investors  interest at the rate of 18% per annum on
the Stated Value of the Preferred Stock (the "LOSS  AMOUNT"),  for the period of
time  that the  Company  is late in filing  the  Registration  Statement  and in
causing the Registration  Statement to be declared  effective as a result of the
Company's breach of Sections 2(a) and/or 2(b)(i). In addition, the Company shall
pay  the  Loss  Amount  to the  Investors  for  the  period  of  time  that  the
Registration  Statement has not been declared effective  commencing on the 150th
day after the filing of such  Registration  Statement  through  the day that the
Registration  Statement  is declared  effective.  The  Company  shall pay to the
Investors  the  compensation  described  upon demand by and in  accordance  with
instructions  given to the Company by the Investors.  Nothing herein shall limit
the Investors'  right to pursue actual damages and/or its remedies at law and in
equity for the Company's breach of Sections 2(a) and/or 2(b)(i).

       2A. COMPANY REGISTRATION.

          (a) In addition to the  registration  rights set forth in Section 2 of
this Agreement,  if the Company proposes to register (including for this purpose
a  registration  effected  by  the  Company  for  stockholders  other  than  the
Investors)  any of its capital  stock or other  securities  convertible  into or
exchangeable  for Common Stock under the  Securities  Act in connection  with

                                       5
<PAGE>

an underwritten  public offering of such securities  solely for cash (other than
registration  statements on Form S-4 or S-8 or a registration statement relating
to the sale of  securities to  participants  in a Company stock option plan or a
registration  in which the only Common  Stock being  registered  is Common Stock
issuable upon  conversion of debt securities  which are also being  registered),
the Company shall, at such time,  promptly give each seller of Restricted  Stock
written notice of such registration.  Upon the written request of each seller of
Restricted  Stock  given  within 20 days after the giving of such  notice by the
Company in accordance  with this Section 2A, the Company  shall,  subject to the
provisions of Section 2A(c), cause to be registered under the Securities Act all
of the Restricted  Stock that each such seller of Restricted Stock has requested
to be registered.

          (b) The  right of any  seller  of  Restricted  Stock  to  registration
pursuant  to  this  Section  2A  shall  be   conditioned   upon  such   seller's
participation in such underwriting and the inclusion of such seller's Restricted
Stock  in the  underwriting  to the  extent  provided  herein.  All  sellers  of
Restricted  Stock  proposing  to  distribute   their  securities   through  such
underwriting  shall  (together  with  the  Company  and  the  other  sellers  of
securities  of the  Company  with  registration  rights to  participate  therein
distributing  their  securities   through  such  underwriting)   enter  into  an
underwriting  agreement  in  customary  form  with  the  representative  of  the
underwriter or underwriters selected by the Company.

          (c)  Notwithstanding  any other  provisions to this Section 2A, if the
representative of the underwriters advises the Company in writing that marketing
factors  make  a  limitation  on  the  number  of  shares  to  be   underwritten
appropriate, the representative may (subject to the limitations set forth below)
exclude all Restricted Stock from, or limit the number of Restricted Stock to be
included in, the registration and underwriting.  The Company shall so advise all
sellers  of  securities  requesting  registration,  and the  number of shares of
securities that are entitled to be included in the registration and underwriting
shall be allocated  first to the Company for  securities  being sold for its own
account,  second, to the sellers of Restricted Stock and third, for stockholders
other than the  Investors.  If any  Investor  does not agree to the terms of any
such  underwriting,  it shall be excluded  therefrom by written  notice from the
Company or the underwriter. Any Restricted Stock or other securities excluded or
withdrawn  from such  underwriting  shall be  withdrawn  from such  registration
without  prejudice  to  include  such  withdrawn  shares in future  underwritten
registrations pursuant to this Section 2A.

       3.  EXPENSES.  All  expenses  incurred by the Company in  complying  with
Section 2, including,  without  limitation,  all  registration  and filing fees,
printing  expenses,  fees and  disbursements  of counsel and independent  public
accountants for the Company, fees and expenses (including counsel fees) incurred
in connection  with complying with state  securities or "blue sky" laws, fees of
the National  Association of Securities  Dealers,  Inc., transfer taxes, fees of
transfer agents and  registrars,  and costs of insurance and reasonable fees and
disbursements of one counsel for the sellers of Restricted  Stock, but excluding
any Selling Expenses and fees and disbursements of any other counsel for, or any
accountant or agent of, a seller of Restricted  Stock, are called  "REGISTRATION
EXPENSES." All underwriting  discounts and selling commissions applicable to the
sale of Restricted Stock are called "SELLING EXPENSES."

                                       6
<PAGE>

       The  Company  will  pay all  Registration  Expenses  and the  sellers  of
Restricted Stock will pay all Selling Expenses.  In addition,  the Company shall
pay all of the sellers of Restricted  Stock  reasonable  costs  (including legal
fees) incurred in connection  with the  successful  enforcement of such seller's
rights hereunder.

       4. INDEMNIFICATION AND CONTRIBUTION.

          (a) In connection  with the  registration  and sale of the  Restricted
Stock pursuant to the Registration Statement, to the fullest extent permitted by
law, the Company will indemnify and hold harmless each seller of such Restricted
Stock  thereunder  together with such seller's  officers,  directors,  partners,
employees and agents,  each  underwriter of such Restricted Stock thereunder and
each other person,  if any, who controls such seller or  underwriter  within the
meaning  of  the  Securities  Act,  against  any  losses,   claims,  damages  or
liabilities,  joint or several, to which such seller and such seller's officers,
directors, partners, employees and agents, underwriter or controlling person may
become subject under the  Securities  Act or otherwise,  insofar as such losses,
claims,  damages or liabilities (or actions in respect  thereof) arise out of or
are based  upon (i) any untrue  statement  or alleged  untrue  statement  of any
material  fact  contained  in  the  Registration   Statement,   any  preliminary
prospectus or final prospectus contained therein, or any amendment or supplement
thereof, or (ii) arise out of or are based upon the omission or alleged omission
to state therein a material  fact required to be stated  therein or necessary to
make the statements  therein not  misleading,  and will promptly  reimburse each
such seller,  each such underwriter and each such  controlling  person (iii) any
violation  or alleged  violation  or  alleged  violation  by the  Company of the
Securities Act, the Exchange Act, any other law, including,  without limitation,
any state securities law, or any rule or regulation  thereunder  relating to the
offer or sale of the Restricted Stock pursuant to a Registration Statement; (but
not such seller's failure to comply with the prospectus delivery requirements or
other rules and  regulations  under the Exchange  Act relating to such  seller's
conduct  in  offering  and  selling  Restricted  Stock)  for any  legal or other
expenses  reasonably  incurred  by  them in  connection  with  investigating  or
defending any such loss, claim, damage, liability or action, PROVIDED,  HOWEVER,
that the  Company  will not be liable in any such case if and to the extent that
any such  loss,  claim,  damage or  liability  arises out of or is based upon an
untrue  statement or alleged untrue statement or omission or alleged omission so
made in  conformity  with  information  furnished by any such  seller,  any such
underwriter or any such  controlling  person in writing  specifically for use in
the Registration  Statement or such  prospectus.  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  Restricted  Stock by
sellers pursuant to Section 7(a) of this Agreement.

          (b) In connection with the  registration  and sale of Restricted Stock
pursuant to the  Registration  Statement,  each seller of such Restricted  Stock
thereunder,  severally  and not jointly,  will  indemnify  and hold harmless the
Company, each person, if any, who controls the Company within the meaning of the
Securities  Act,  each  officer  of  the  Company  who  signs  the  Registration
Statement,  each director of the Company,  each  underwriter and each person who
controls any underwriter  within the meaning of the Securities Act,  against all
losses, claims,  damages or liabilities,  joint or several, to which the Company
or such officer, director,  underwriter or controlling person may become subject
under the Securities Act or otherwise,  insofar as such losses,  claims, damages
or  liabilities  (or actions in respect  thereof) arise out of or

                                       7
<PAGE>

are based upon any untrue  statement or alleged untrue statement of any material
fact contained in the  Registration  Statement,  any  preliminary  prospectus or
final prospectus  contained therein,  or any amendment or supplement thereof, or
arise out of or are based upon the omission or alleged omission to state therein
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein not misleading,  and will promptly reimburse the Company and
each such officer, director, underwriter and controlling person for any legal or
other expenses  reasonably  incurred by them in connection with investigating or
defending any such loss, claim, damage, liability or action, PROVIDED,  HOWEVER,
that such  seller will be liable  hereunder  in any such case if and only to the
extent that any such loss, claim,  damage or liability arises out of or is based
upon an untrue  statement  or alleged  untrue  statement  or omission or alleged
omission made in reliance upon and in conformity with information  pertaining to
such  seller,  as such,  furnished  in  writing to the  Company  by such  seller
specifically  for use in the  Registration  Statement  or such  prospectus,  and
PROVIDED, FURTHER, HOWEVER, that the liability of each seller hereunder shall be
limited to the proportion of any such loss, claim, damage,  liability or expense
which is equal to the  proportion  that the public  offering price of the shares
sold by such seller under the  Registration  Statement bears to the total public
offering price of all securities sold thereunder, but not in any event to exceed
the net  proceeds  received  by such seller  from the sale of  Restricted  Stock
covered by such registration statement.

          (c) Promptly after receipt by an indemnified party hereunder of notice
of the commencement of any action,  such indemnified  party shall, if a claim in
respect thereof is to be made against the indemnifying  party hereunder,  notify
the  indemnifying  party in writing  thereof,  but the omission so to notify the
indemnifying  party shall not relieve it from any liability which it may have to
such indemnified party other than under this Section 4 and shall only relieve it
from any  liability  which  it may have to such  indemnified  party  under  this
Section 4 if and to the  extent the  indemnifying  party is  prejudiced  by such
omission. In case any such action shall be brought against any indemnified party
and it shall notify the  indemnifying  party of the  commencement  thereof,  the
indemnifying  party shall be entitled  to  participate  in and, to the extent it
shall  wish,  to  assume  and   undertake  the  defense   thereof  with  counsel
satisfactory to such indemnified  party, and, after notice from the indemnifying
party to such  indemnified  party of its election so to assume and undertake the
defense thereof,  the indemnifying party shall not be liable to such indemnified
party under this Section 4 for any legal expenses  subsequently incurred by such
indemnified  party in connection  with the defense thereof other than reasonable
costs of  investigation  and of  liaison  with  counsel so  selected,  PROVIDED,
HOWEVER, that, if the defendants in any such action include both the indemnified
party and the indemnifying party and the indemnified party shall have reasonably
concluded  that  there  may be  reasonable  defenses  available  to it which are
different from or additional to those available to the indemnifying  party or if
the interests of the indemnified party reasonably may be deemed to conflict with
the interests of the indemnifying  party,  the indemnified  party shall have the
right to  select a  separate  counsel  and to assume  such  legal  defenses  and
otherwise to  participate  in the defense of such action,  with the expenses and
fees of such separate counsel and other expenses  related to such  participation
to be reimbursed by the indemnifying party as incurred.

          (d) In order to provide for just and equitable  contribution  to joint
liability under the Securities Act in any case in which either (i) any seller of
Restricted  Stock pursuant to the  Registration  Statement,  or any  controlling
person of any such holder,  makes a claim for

                                       8
<PAGE>

indemnification  pursuant to this Section 4 but it is judicially  determined (by
the entry of a final judgment or decree by a court of competent jurisdiction and
the expiration of time to appeal or the denial of the last right of appeal) that
such  indemnification may not be enforced in such case  notwithstanding the fact
that  this  Section  4  provides  for  indemnification  in  such  case,  or (ii)
contribution  under the  Securities  Act may be required on the part of any such
selling  holder  or any such  controlling  person  in  circumstances  for  which
indemnification  is provided  under this Section 4; then, and in each such case,
the Company and such holder will  contribute  to the aggregate  losses,  claims,
damages or  liabilities to which they may be subject  (after  contribution  from
others) in such  proportion so that such holder is  responsible  for the portion
represented by the percentage  that the public  offering price of its Restricted
Stock offered by the  registration  statement bears to the public offering price
of all securities  offered by such  registration  statement,  and the Company is
responsible  for the remaining  portion;  PROVIDED,  HOWEVER,  that, in any such
case,  (A) no such holder will be required to contribute any amount in excess of
the public offering price of all such Restricted Stock offered by it pursuant to
such  registration  statement;  and (B) no person or entity guilty of fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
will be entitled to contribution from any person or entity who was not guilty of
such fraudulent misrepresentation.

       5. CHANGES IN COMMON STOCK OR PREFERRED STOCK. If, and as often as, there
is any  change  in the  Common  Stock or the  Preferred  Stock by way of a stock
split,  stock dividend,  combination or  reclassification,  or through a merger,
consolidation,  reorganization  or  recapitalization,  or by  any  other  means,
appropriate adjustment shall be made in the provisions hereof so that the rights
and privileges granted hereby shall continue with respect to the Common Stock or
the Preferred Stock as so changed.

       6. RULE 144  REPORTING.  With a view to making  available the benefits of
certain rules and regulations of the Commission which may at any time permit the
sale of the  Restricted  Stock to the public without  registration,  the Company
agrees to:

          (a) make and keep  public  information  available,  as those terms are
understood and defined in Rule 144 under the Securities Act;

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

          (c) promptly upon the request of a holder of Restricted  Stock who has
sold shares in compliance with Rule 144, furnish,  at the Company's expense,  an
opinion of counsel  stating  that such sale is in  compliance  with Rule 144 and
directing the Company's  transfer agent (i) to remove any applicable legends and
(ii) to transfer the shares.

          (d) furnish to each Investor so long as such Investor owns  Restricted
Stock, 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 such Investor to
sell such securities pursuant to Rule 144 without registration.

respective successors and assigns of the parties hereto (including  transferees,
in  accordance  with  applicable  federal  and  state  securities  laws,  of any
Preferred  Stock or Restricted  Stock),  whether so expressed or not,  PROVIDED,
HOWEVER,  that registration  rights conferred herein on the holders of Preferred

          (b) All notices, requests, consents and other communications hereunder
shall be in writing  and shall be deemed  sufficient  when  delivered  in person

set forth in the Investor's Counterpart Signature Page;

          if to any subsequent holder of Preferred Stock or Restricted Stock, to

number as shall have been  furnished in writing to the Company (in the case of a
holder of Preferred  Stock or  Restricted  Stock) or to the holders of Preferred
Stock or Restricted  Stock (in the case of the Company) in  accordance  with the
provisions of this paragraph.

          (c) This  Agreement  shall be governed by and  construed in accordance
with the laws of the State of New York, without regard to principles of conflict
of laws.

          (d) This Agreement and the applicable  Purchase  Agreement  constitute

supersedes all prior  agreements,  understandings,  negotiations and discussions
relating to such subject matter.

          (e) This  Agreement  may not be amended or modified,  and no provision
hereof may be waived, without the written consent of the Company and the holders
of a  majority  of  the  Restricted  Stock,  assuming  conversion  of all of the
outstanding  Preferred Stock and exercise of the outstanding  Warrants as of the
date such consent is given.

          (f) This Agreement may be executed in two or more  counterparts,  each
of which shall be deemed an original, but all of which together shall constitute
one and the same instrument.

          (g) If any  provision of this  Agreement  shall be held to be illegal,
invalid or unenforceable,  such illegality, invalidity or unenforceability shall
attach  only to such  provision  and  shall not in any  manner  affect or render
illegal,  invalid or  unenforceable  any other provision of this Agreement,  and
this  Agreement  shall  be  carried  out  as if any  such  illegal,  invalid  or
unenforceable provision were not contained herein.

          (h) From and after the date of this Agreement,  the Company shall not,

giving such holder or prospective holder any registration rights with terms more
favorable  than or  inconsistent  with the  registration  rights  granted to the
Investors hereunder.

          (i)  Additional  Investors  shall become  parties to this Agreement by
completing,  executing and  delivering to the Company and each other Investor an

       This Amended and Restated Co-Sale Agreement,  dated as of the 29th day of
September,  2000,  is by and  among  Dr.  Arol I.  Buntzman  (the  "Executive"),
Educational Video Conferencing, Inc., a Delaware corporation (the "Company") and
the Investors.

       This  Agreement  amends and  restates  the Amended  Restated  and Co-Sale
Agreement  dated as of September  27, 2000,  among the  Executive,  the Company,
Paloma  Strategic  Fund L.P.,  Seneca  Capital  International,  Ltd.  and Seneca
Capital, L.P.

       In consideration  of the mutual  covenants set forth herein,  the parties
agree as follows:

1.     DEFINITIONS.

       (a) "Common  Stock" shall mean the  Company's  common  stock,  $.0001 par
value per share.

       (b)  "Co-Sale  Shares"  shall mean all  Shares now owned or  subsequently
acquired by the Executive and all Shares  acquired by the Investors  pursuant to
the Stock Purchase Agreement.

       (c)  "Co-Sale  Transaction"  shall mean a  privately  negotiated  sale or
transfer  of any Shares  with any third party or a block lot sale or transfer of
any Shares with a broker and shall not include sales pursuant to Rule 144.

       (d) "Investors"  shall mean,  collectively,  Paloma  Strategic Fund L.P.,
Seneca Capital  International,  Ltd.,  Seneca  Capital,  L.P.,  Merced  Partners
Limited Partnership,  Lakeshore International,  Ltd. and the other purchasers of
Preferred  Stock and  Warrants  pursuant to the Stock  Purchase  Agreement  that
become parties to this Agreement in accordance with Section 5(l) below.

       (e)  "Preferred  Stock"  shall mean the  Company's  outstanding  Series B
Preferred Stock owned by the Investors.

       (f) "Rule 144" shall mean Rule 144  promulgated  under the Securities Act
of 1933 (or any successor to such rule).

       (g)  "Shares"  shall mean all shares of Common Stock and all Common Stock
equivalents (including without limitation, shares of Preferred Stock and Warrant
Shares).  For the  purposes of any  computation  of the amount of Shares  either
outstanding  or held by a  stockholder  who or which is a party to this  Co-Sale
Agreement, all Common Stock equivalents held by such stockholder shall be deemed
to be  converted,  exercised or exchanged  for shares of Common Stock whether or
not such conversion, exercise or exchange has actually been effected and whether
or not then convertible, exercisable or exchangeable (but only to the extent any
such Common Stock equivalents shall be vested).

       (h) "Stock Purchase  Agreement"  shall mean,  collectively,  the Series B
Stock Purchase Agreements between the Company and the Investors, respectively.

<PAGE>

       (i)  "Warrant  Shares"  shall mean,  with respect to the  Investors,  all
shares  which are  issuable  in the form of Common  Stock upon  exercise  of the
Warrants issued pursuant to the Stock Purchase Agreement.

2.     CO-SALE TRANSACTION.

       (a)  Except as set forth in  Section 3, if the  Executive  (the  "Selling
Party") proposes to sell or transfer any of its Shares,  then such Selling Party
shall give  written  notice  (the  "Notice")  to the  Company and to each of the
Investors at least 10 days prior to the closing of a Co-Sale  Transaction and at
least 3 days prior to the closing or  settlement  of any other sale or transfer.
The Notice shall  indicate the number of Shares to be sold or  transferred,  the
nature of such sale or transfer and, if known, the consideration to be paid, and
the name and address of each prospective  purchaser or transferee.  In the event
that the sale or transfer is being made pursuant to the  provisions of Section 3
hereof,  the Notice shall state under which paragraph and  subparagraph the sale
or transfer is being  made.  A notice of proposed  sales under Rule 144 shall be
sufficient  if  the  Executive  provides  the  Investors  with  a  copy  of  the
Executive's Form 144.

       (b) To the extent that the Notice pertains to a Co-Sale Transaction, each
Investor shall have the right,  exercisable  upon written notice to such Selling
Party (the "Notice of Acceptance") within 5 days after receipt of the Notice, to
participate  in such sale on the same  terms  and  conditions  specified  in the
Notice.  To the extent that one or more of the Investors  exercise such right of
participation  in accordance with the terms and conditions set forth below,  the
number of Co-Sale  Shares  that the  Selling  Party may sell in the  transaction
shall be correspondingly reduced.

       (c) In a Co-Sale  Transaction,  each Investor may sell all or any part of
that  number  of  shares  of  Common  Stock  equal to the  product  obtained  by
multiplying (i) the aggregate  number of Co-Sale Shares covered by the Notice by
(ii) a fraction,  the  numerator  of which is the number of Shares  owned by the
Investor at the time of the sale or transfer and the denominator of which is the
total number of Shares owned by the  Executive  and Investors at the time of the
sale or transfer. An Investor may request in the Notice of Acceptance to sell in
excess of its pro rata  percentage of the Co-Sale Shares in which case the right
to sell any Co-Sale  Shares not elected to be sold by other  Investors  shall be
allocated  among  Investors who so elect.  Each such electing  Investor shall be
permitted to sell up to that portion of such excess  Co-Sale Shares equal to the
ratio that its pro rata percentage  bears to the pro rata percentage of all such
electing Investors.

       (d) Each Investor shall effect its participation in a Co-Sale Transaction
by promptly  delivering  to the Selling  Party for  transfer to the  prospective
purchaser  one or more  certificates,  properly  endorsed  for  transfer,  which
represent:

               (i) the type and number of  Co-Sale  Shares  which such  Investor
       elects to sell; or

               (ii) that  number of shares of  Preferred  Stock which is at such
       time  convertible  into the number of shares of Common  Stock  which such
       Investor  elects  to sell;  provided,  however,  that if the  prospective
       purchaser  objects to the delivery of  Preferred  Stock in lieu of Common
       Stock, such Investor shall convert such Preferred Stock into Common

                                       2

       Stock and deliver Common Stock as provided in subparagraph 2(d)(i) above,
       and the Company agrees to make any such  conversion  concurrent  with the
       actual transfer of such Co-Sale Shares to the purchaser; or

               (iii)  that  number  of  Warrant  Shares  which  is at such  time
       exercisable into the number of shares of Common Stock which such Investor
       elects to sell;  provided,  however,  that if the  prospective  purchaser
       objects to the delivery of Warrant  Shares in lieu of Common Stock,  such
       Investor  shall  exercise such Warrant Shares into shares of Common Stock
       and deliver such Common Stock as provided in subparagraph  2(d)(i) above,
       and the  Company  agrees  to make any such  exercise  of  Warrant  Shares
       concurrent  with  the  actual  transfer  of such  Co-Sale  Shares  to the
       purchaser.

       (e) The stock  certificate or certificates  that the Investor delivers to
the  Selling  Party  pursuant  to  paragraph  2(d) shall be  transferred  to the
prospective purchaser in consummation of the sale of the Co-Sale Shares pursuant
to the terms and conditions specified in the Notice, and the Selling Party shall
concurrently  therewith remit to such Investor that portion of the sale proceeds
to which such Investor is entitled by reason of such Investor's participation in
such sale.  To the extent  that any  prospective  purchaser(s),  prohibits  such
assignment or otherwise  refuses to purchase shares or other  securities from an
Investor  exercising  rights of co-sale  hereunder,  the Selling Party shall not
sell to such  prospective  purchaser or purchasers any Co-Sale Shares unless and
until,  simultaneously  with such sale,  the Selling  Party shall  purchase such
shares or other securities from such Investor.

       (f) The exercise or non-exercise  of the rights of an Investor  hereunder
to  participate  in one or more sales of Co-Sale  Shares made by a Selling Party
shall not adversely  affect such Investor's  rights to participate in subsequent
sales of Co-Sale Shares subject to paragraph 2(a).

       (g) If none of the  Investors  elects to  participate  in the sale of the
Co-Sale Shares  subject to the Notice,  the Selling Party may, not later than 60
days following  delivery to the Company and each of the Investors of the Notice,
enter into an agreement providing for the closing of the transfer of the Co-Sale
Shares  covered  by the  Notice  within 30 days of such  agreement  on terms and
conditions  not more  favorable to the  transferor  than those  described in the
Notice.  Any proposed transfer on terms and conditions more favorable than those
described in the Notice,  as well as any subsequent  proposed transfer of any of
the Co-Sale Shares by the Selling  Party,  shall again be subject to the co-sale
rights of the Investors  and shall require  compliance by the Selling Party with
the procedures described in this Section 2.

       (h) (i) In the event a Selling Party should sell any Co-Sale  Shares in a
Co-Sale  Transaction  in  contravention  of the co-sale  rights of the Investors
under this Co-Sale  Agreement  (a  "Prohibited  Transfer"),  each  Investor,  in
addition  to such  other  remedies  as may be  available  at law,  in  equity or
hereunder,  shall have the option,  exercisable by written notice to the Selling
Party within 90 days after becoming aware of the Prohibited Transfer as provided
below, and the Selling Party shall be bound by the applicable provisions of such
option.

               (ii) In the event of a  Prohibited  Transfer by a Selling  Party,
       each Investor shall have the right to sell to such Selling Party the type
       and number of shares of Common  Stock  equal to the number of shares each
       Stockholder  would have been entitled to

                                       3

<PAGE>

       transfer to the purchaser under Section 2(c) had the Prohibited  Transfer
       hereof been effected pursuant to and in compliance with the terms hereof.
       Such sale shall be made on the following terms and conditions:

               (A) The price per share at which the shares are to be sold to the
          Selling  Party  shall be  equal to the  price  per  share  paid by the
          purchaser to the Selling Party in the Prohibited Transfer. The Selling
          Party  shall also  reimburse  each  Investor  for any and all fees and
          expenses,  including legal fees and expenses, incurred pursuant to the
          exercise or the  attempted  exercise of the  Investor's  rights  under
          Section 2.

               (B)  Within  90 days  after  the  later of the dates on which the
          Investor  (i)  received  notice  of the  Prohibited  Transfer  or (ii)
          otherwise  became  aware of the  Prohibited  Transfer,  each  Investor
          shall, if exercising the option created hereby, deliver to the Selling
          Party the certificate or certificates  representing shares to be sold,
          each certificate to be properly endorsed for transfer.

               (C) The Selling Party shall,  upon receipt of the  certificate or
          certificates  for the shares to be sold by an  Investor,  pursuant  to
          this subparagraph  2(h)(ii), pay the aggregate purchase price therefor
          and the amount of  reimbursable  fees and  expenses,  as  specified in
          subparagraph 2(h)(ii)(A),  in cash or by other means acceptable to the
          Investor.

               (D) Notwithstanding the foregoing, any attempt by a Selling Party
          to transfer  Co-Sale  Shares in violation of Section 2 hereof shall be
          void. The Company agrees it will not knowingly  effect such a transfer
          nor will it knowingly treat any alleged transferee in such transfer as
          the holder of such shares without the written consent of a majority in
          interest of the Investors.

3.     EXEMPT TRANSFERS.

       Notwithstanding  the  foregoing,  the  provisions of Sections 2 shall not
apply to (i) any transfer or transfers of Shares to any third party  (subject to
compliance  with  Federal  and  State  securities  laws) not  exceeding,  in the
aggregate,  twenty-five  percent (25%) of the Executive's total number of Shares
outstanding  as of the date  hereof;  or (ii)  any  transfer  to the  ancestors,
descendants,  siblings or spouse of the Executive; or to trusts, for the benefit
of such persons; provided, that, (A) the Executive shall inform the Investors of
such transfer prior to effecting it and (B) the transferee or beneficiary  shall
furnish the  Investors  with a written  agreement to be bound by and comply with
all  provisions  of  Section  2 or (iii)  any gift  for no  consideration  to an
organized  charity  that  is not an  affiliate  of the  Executive  or any of the
persons or trusts  referred  to in Section  3(ii).  Transferred  Co-Sale  Shares
referred to in Section 3 (ii) shall remain "Co-Sale Shares" hereunder,  and such
transferee or beneficiary shall be treated as an Executive,  for the purposes of
this Co-Sale Agreement.
