Item 5. Other Events.

     On May 29, 1998, Compositech Ltd. (the "Company") issued 220 shares of 7%
Series B Convertible Preferred Stock (the "Preferred Stock") aggregating $2.2
million in a private placement. The net proceeds of approximately $1,900,000
will be used for working capital and equipment.

     Holders of the Preferred Stock are entitled to dividends on a cumulative
basis,  payable  quarterly  in cash or common stock at the option of the Company
except under certain  conditions  requiring the payment in cash. In the event of
any  voluntary  or  involuntary  liquidation  of  the  Company,  holders  of the
Preferred  Stock shall be  entitled  to receive the stated  value of $10,000 per
share plus all due but unpaid  dividends before any distribution or payments are
made to holders of the Company's Series A convertible  preferred stock or common
stock.  The  Preferred  Stock  does not have  voting  rights  except in  certain
circumstances.

     Each share of the Preferred Stock is convertible at the option of the
holder into shares of the Company's common stock from the earlier of August 27,
1998 or the date that a Registration Statement for the underlying shares of
common stock is declared effective by the SEC. The shares of the Preferred Stock
are convertible through May 29, 2000, at which time any remaining shares will be
automatically converted into common stock. The conversion price for each share
of the Preferred Stock is the lesser of $3.00 and 87 1/2% of the average five
lowest daily trade prices of the Company's common stock during the 20 trading
days preceding the conversion date, subject to a floor price of $1.50 per share.

     The underlying agreements provide for redemption in cash at the Company's
option and mandatory redemption at the holders option under certain
circumstances relating to, among others, the maintenance of listing of shares of
the Company's common stock on a major exchange. The redemption price would be
generally equivalent to the amount obtained if the Preferred Stock was converted
into common stock at the then existing conversion price. The agreements also
provide for adjustment of the conversion prices under certain circumstances.

     In addition to a cash commission, the Company issued warrants to purchase
125,000 shares of its common stock at $2.50 per share exercisable until May 29,
2003 as a finder's fee in connection with the foregoing transactions.

                                                                         ANNEX A

                            Terms of Preferred Stock

     Section 1. Designation, Amount and Par Value. The series of preferred stock
shall be designated as 7% Series B Convertible  Preferred  Stock (the "Preferred
Stock") and the number of shares so designated  shall be 220 (which shall not be
subject to increase  without the consent of the holders of the  Preferred  Stock
(each, a "Holder" and  collectively,  the  "Holders"));  Each share of Preferred
Stock shall have a par value of $.01 and a stated  value of $10,000 (the "Stated
Value").

     Section 2. Dividends.

     (a) Holders of  Preferred  Stock shall be entitled to receive,  when and as
declared by the Board of Directors out of funds legally available therefor,  and
the  Company  shall  pay,  cumulative  dividends  at the  rate per  share  (as a
percentage  of the Stated Value per share)  equal to 7% per annum,  payable on a
quarterly basis on March 31, June 30,  September 30 and December 31 of each year
during the term hereof (each a "Dividend Payment Date"),  commencing on June 30,
1998, in cash or shares of Common Stock (as defined in Section 8) at, subject to
the terms and conditions set forth herein, the option of the Company.  Dividends
on the Preferred Stock shall be calculated on the basis of a 360-day year, shall
accrue daily  commencing  on the Original  Issue Date (as defined in Section 8),
and shall be deemed to accrue  from such date  whether or not earned or declared
and  whether or not there are  profits,  surplus or other  funds of the  Company
legally  available for the payment of  dividends.  Any dividends not paid on any
Dividend Payment Date shall continue to accrue and shall be due and payable upon
conversion of the Preferred  Stock. A party that holds shares of Preferred Stock
on a Dividend Payment Date will be entitled to receive such dividend payment and
any other  accrued and unpaid  dividends  which  accrued  prior to such Dividend
Payment Date,  without regard to any sale or disposition of such Preferred Stock
subsequent  to the  applicable  record  date.  All  overdue  accrued  and unpaid
dividends and other amounts due herewith  shall entail a late fee at the rate of
15% per annum (to accrue  daily,  from the date such  dividend is due  hereunder
through and including the date of payment). Except as otherwise provided herein,
if at any time the Company  pays less than the total  amount of  dividends  then
accrued on account of the Preferred  Stock,  such payment  shall be  distributed
ratably  among the Holders  based upon the number of shares held by each Holder.
Payment of dividends on the Preferred Stock is further subject to the provisions
of  Section  5(c)(i).  The  Company  shall  provide  the  Holders  notice of its
intention  to pay  dividends  in cash or shares of Common Stock not less than 10
Trading  Days  prior  to the  Dividend  Payment  Date for so long as  shares  of
Preferred  Stock  are  outstanding.  If  dividends  are paid in shares of Common
Stock, the number of shares of Common Stock issuable on account of such dividend
shall  equal the cash  amount of such  dividend on such  Dividend  Payment  Date
divided by the Conversion Price (as defined below) on such date.

     (b) Notwithstanding  anything to the contrary contained herein, the Company
may not issue shares of Common  Stock in payment of dividends  (and must deliver
cash in respect thereof) on the Preferred Stock if:



<PAGE>


          (i) the  number  of shares  of  Common  Stock at the time  authorized,
     unissued  and  unreserved  for all  purposes  is  insufficient  to pay such
     dividends in shares of Common Stock;

          (ii) such  shares  of  Common  Stock  are not  registered  for  resale
     pursuant to an effective registration statement that names the recipient of
     such  dividend  as a  selling  stockholder  thereunder  and may not be sold
     without  volume  restrictions  pursuant to Rule 144  promulgated  under the
     Securities Act of 1933, as amended (the "Securities Act"), as determined by
     counsel to the Company  pursuant to a written opinion letter,  addressed to
     the Company's  transfer  agent in the form and substance  acceptable to the
     Holders and such transfer agent;

          (iii) the Common  Stock is not then  listed for  trading on the Nasdaq
     SmallCap Market (the "NASDAQ") or on the New York Stock Exchange,  American
     Stock Exchange or Nasdaq National Market (each a "Subsequent Market");

          (iv)  the  Company  has  failed  to  timely   satisfy  its  conversion
     obligations hereunder; or

          (v) the  issuance of such shares of Common  Stock would  result in the
     recipient  thereof  beneficially  owning,  as determined in accordance with
     Rule  13d-3  promulgated  under the  Securities  Exchange  Act of 1934,  as
     amended  (the  "Exchange  Act"),  more than  4.999% of the then  issued and
     outstanding shares of Common Stock.

     Payment of  dividends  hereunder  in shares of Common  Stock  shall also be
subject to the provisions of Section 5(a)(iii).

     (c) So long as any Preferred  Stock shall remain  outstanding,  neither the
Company nor any subsidiary  thereof shall redeem,  purchase or otherwise acquire
directly  or  indirectly  any Junior  Securities  (as defined in Section 8), nor
shall the Company directly or indirectly pay or declare any dividend or make any
distribution  (other than a dividend  or  distribution  described  in Section 5)
upon, nor shall any  distribution be made in respect of, any Junior  Securities,
nor shall any monies be set aside for or applied to the  purchase or  redemption
(through a sinking fund or  otherwise)  of any Junior  Securities or shares pari
passu with the Preferred Stock,  except for repurchases  effected by the Company
on the open market, pursuant to a direct stock purchase plan.

     Section  3.  Voting  Rights.  Except as  otherwise  provided  herein and as
otherwise  required by law,  the  Preferred  Stock shall have no voting  rights.
However,  so long as any shares of Preferred Stock are outstanding,  the Company
shall not and shall cause its  subsidiaries not to, without the affirmative vote
of the Holders of all of the shares of the Preferred Stock then outstanding, (i)
alter or  change  adversely  the  powers,  preferences  or  rights  given to the
Preferred  Stock,  (b)  alter or amend  this  Certificate  of  Designation,  (c)
authorize or create any class of stock  ranking as to dividends or  distribution
of assets upon a  Liquidation  (as defined in Section 4) senior to or  otherwise
pari  passu  with or senior to the  Preferred  Stock,  except  for any

<PAGE>

series of  Preferred  Stock  issued  and sold in  accordance  with the  Purchase
Agreement,  (d) amend its Certificate of Incorporation,  bylaws or other charter
documents so as to affect adversely any rights of any Holders,  (e) increase the
authorized  number of shares of Preferred Stock, or (f) enter into any agreement
with respect to the foregoing.

     Section 4. Liquidation. Upon any liquidation,  dissolution or winding-up of
the Company,  whether  voluntary or involuntary (a  "Liquidation"),  the Holders
shall be  entitled  to receive out of the assets of the  Company,  whether  such
assets are capital or surplus, for each share of Preferred Stock an amount equal
to the  Stated  Value  plus all due but  unpaid  dividends  per  share,  whether
declared or not, before any distribution or payment shall be made to the holders
of any Junior Securities, and if the assets of the Company shall be insufficient
to pay in full such  amounts,  then the entire assets to be  distributed  to the
Holders of Preferred  Stock shall be distributed  among the Holders of Preferred
Stock ratably in accordance with the respective amounts that would be payable on
such shares if all amounts payable thereon were paid in full. A sale, conveyance
or disposition of all or  substantially  all of the assets of the Company or the
effectuation  by the Company of a transaction or series of related  transactions
in which more than 33% of the voting  power of the Company is disposed  of, or a
consolidation  or  merger  of the  Company  with or into any  other  company  or
companies shall not be treated as a Liquidation, but instead shall be subject to
the  provisions of Section 5. The Company shall mail written  notice of any such
Liquidation,  not less than 45 days prior to the payment date stated therein, to
each record Holder of Preferred Stock.

     Section 5. Conversion.

     (a)(i)  Optional  Conversions.  Each  share  of  Preferred  Stock  shall be
convertible  into  shares of Common  Stock  (subject  to  reduction  pursuant to
Section  5(a)(iii)  hereof and Section  3.8 of the  Purchase  Agreement)  at the
Conversion  Ratio (as defined in Section 8) at the option of the Holder,  at any
time and from  time to time,  from and  after  the  earlier  of (i) the date the
Underlying  Securities  Registration  Statement  (as  defined  in  Section 8) is
declared effective by the Securities and Exchange Commission (the "Commission"),
or (ii) the 90th day  following  the Original  Issue Date.  Holders shall effect
conversions by surrendering  the certificate or  certificates  representing  the
shares of Preferred Stock to be converted to the Company, together with the form
of conversion notice attached hereto as Exhibit A (a "Conversion Notice").  Each
Conversion  Notice shall  specify the number of shares of Preferred  Stock to be
converted and the date on which such  conversion  is to be effected,  which date
may not be prior to the date the  Holder  delivers  such  Conversion  Notice  by
facsimile  (the  "Conversion  Date").  If no  Conversion  Date is specified in a
Conversion  Notice,  the  Conversion  Date shall be the date that the Conversion
Notice is deemed delivered hereunder.  If the Holder is converting less than all
shares  of  Preferred  Stock  represented  by the  certificate  or  certificates
tendered by the Holder with the Conversion Notice, or if a conversion  hereunder
cannot be effected in full for any reason, the Company shall promptly deliver to
such  Holder (in the  manner  and  within the time set forth in Section  5(b)) a
certificate for such number of shares as have not been converted.




                                      -4-
<PAGE>

     (ii) Automatic Conversion. Subject to the provisions in this paragraph, all
outstanding  shares of  Preferred  Stock for which  conversion  notices have not
previously  been received or for which  redemption has not been made or required
hereunder  shall be  automatically  converted on the second  anniversary  of the
Original  Issue  Date at the  Conversion  Price  on such  date.  The  conversion
contemplated  by  this  paragraph  shall  not  occur  if (a)  (1) an  Underlying
Securities Registration Statement that names the Holder as a selling stockholder
thereunder  is not then  effective or (2) the Holder is not  permitted to resell
Underlying Shares pursuant to Rule 144(k)  promulgated under the Securities Act,
without  volume  restrictions,  as  evidenced  by an  opinion  letter of counsel
acceptable to the Holder and the transfer agent for the Common Stock;  (b) there
are not sufficient  shares of Common Stock  authorized and reserved for issuance
upon such  conversion;  or (c) the Company shall have defaulted on its covenants
and obligations hereunder or under the Purchase Agreement or Registration Rights
Agreement.  Further, the number of shares of Preferred Stock that are subject to
conversion pursuant to this section shall be limited to the number of Underlying
Shares which may be issued upon such  conversion  at the  prevailing  Conversion
Price in  accordance  with Section  5(a)(iii).  Any shares (or part  thereof) of
Preferred  Stock which  cannot be converted  at the then  Conversion  Price as a
result of such rule  shall be subject to the  provisions  of Section  5(a)(iii).
Notwithstanding  the foregoing,  the two-year  period for conversion  under this
Section shall be extended (on a day-for-day basis) for any Trading Days that the
Purchaser is unable to resell Underlying  Shares under an Underlying  Securities
Registration  Statement due to (a) a delisting or suspension of the Common Stock
from  trading on the NASDAQ (or any  Subsequent  Market),  (b) the failure of an
Underlying  Securities  Registration  Statement to be declared  effective by the
Commission by the Filing Date (as defined in the Registration Rights Agreement),
or (c) if an  Underlying  Securities  Registration  Statement  shall  have  been
declared  effective  by the  Commission,  (x) the  failure  of  such  Underlying
Securities Registration Statement to remain effective at all times thereafter as
to all  Underlying  Shares,  or (y) the  suspension  of the Holder's  ability to
resell Underlying Shares thereunder.

     (iii) If on any Conversion  Date (A) the Common Stock is listed for trading
on the NASDAQ or the Nasdaq National  Market,  (B) the Conversion  Price then in
effect is such that the  aggregate  number of shares of Common  Stock that would
then be  issuable  upon  conversion  in full of all then  outstanding  shares of
Preferred Stock,  together with any shares of the Common Stock previously issued
upon  conversion  of the shares of  Preferred  Stock and as payment of dividends
thereon,  would equal or exceed 20% of the number of shares of the Common  Stock
outstanding on the Original Issue Date (such number of shares as would not equal
or exceed such 20% limit, the "Issuable Maximum"), and (C) the Company shall not
have previously obtained the vote of shareholders (the "Shareholder  Approval"),
if any,  as may be  required by the rules and  regulations  of The Nasdaq  Stock
Market (or successor thereto) applicable to approve the issuance of Common Stock
in excess of the  Issuable  Maximum  in a private  placement  whereby  shares of
Common  Stock are  deemed to have been  issued at a price  that is less than the
greater of book or fair market value of the Common Stock, then the Company shall
issue to the  Holder so  requesting  a  conversion  a number of shares of Common
Stock equal to the Issuable  Maximum and,  with respect to the  remainder of the
aggregate Stated Value of the 


                                      -5-
<PAGE>

shares of  Preferred  Stock then held by such Holder for which a  conversion  in
accordance with the Conversion Price would result in an issuance of Common Stock
in excess of the Issuable  Maximum (the "Excess Stated  Value"),  the converting
Holder  shall have the option to require  the Company to either (1) use its best
efforts to obtain the Shareholder  Approval  applicable to such issuance as soon
as is possible, but in any event not later than the 60th day after such request,
or (2)(i) issue and deliver to such Holder a number of shares of Common Stock as
equals (x) the Excess  Stated  Value,  plus  accrued  dividends on all shares of
Preferred Stock being converted, divided by (y) the Initial Conversion Price (as
defined  below),  and (ii) cash in an amount equal to the product of (x) the Per
Share Market Value on the Conversion Date and (y) the number of shares of Common
Stock in excess of such  Holder's pro rata portion of the Issuable  Maximum that
would have otherwise  been issuable to the Holder in respect of such  conversion
but for the  provisions of this Section  (such amount of cash being  hereinafter
referred to as the  "Discount  Equivalent"),  or (3) pay cash to the  converting
Holder in an amount  equal to the  Mandatory  Redemption  Amount (as  defined in
Section 8) for the Excess Stated Value. If the Company fails to pay the Discount
Equivalent  or the  Mandatory  Redemption  Amount,  as the case may be,  in full
pursuant  to this  Section  within  seven (7) days after the date  payable,  the
Company will pay interest  thereon at a rate of 15% per annum to the  converting
Holder, accruing daily from the Conversion Date until such amount, plus all such
interest thereon, is paid in full.

     (b)(i) Not later than three (3) Trading Days after any Conversion Date, the
Company will deliver to the Holder (i) a certificate or certificates which shall
be free of  restrictive  legends  and  trading  restrictions  (other  than those
required by Section 3.1(b) of the Purchase Agreement) representing the number of
shares of Common Stock being acquired upon the conversion of shares of Preferred
Stock (subject to reduction pursuant to Section 5(a)(iii) and Section 3.8 of the
Purchase  Agreement),  (ii) one or more certificates  representing the number of
shares of  Preferred  Stock not  converted,  (iii) a bank check in the amount of
accrued  and  unpaid  dividends  (if the  Company  has  elected  to pay  accrued
dividends  in  cash),  and (iv) if the  Company  has  elected  and is  permitted
hereunder  to pay accrued  dividends  in shares of Common  Stock,  certificates,
which shall be free of restrictive legends and trading  restrictions (other than
those required by Section 3.1 (b) of the Purchase Agreement),  representing such
shares  of  Common  Stock;  provided,  however,  that the  Company  shall not be
obligated to issue  certificates  evidencing the shares of Common Stock issuable
upon conversion of any shares of Preferred Stock until  certificates  evidencing
such  shares of  Preferred  Stock are either  delivered  for  conversion  to the
Company or any transfer  agent for the Preferred  Stock or Common Stock,  or the
Holder of such Preferred Stock notifies the Company that such  certificates have
been lost, stolen or destroyed and provides a bond (or other adequate  security)
reasonably  satisfactory  to the Company to indemnify  the Company from any loss
incurred by it in connection  therewith.  The Company shall, upon request of the
Holder,  if  available,  use its best  efforts to  deliver  any  certificate  or
certificates  required  to be  delivered  by  the  Company  under  this  Section
electronically  through the Depository Trust Corporation or another  established
clearing  corporation  performing  similar  functions.  If in  the  case  of any
Conversion  Notice such  certificate  or  certificates,  including  for purposes
hereof,  any  shares of Common  Stock to be  issued  on the  Conversion  Date on
account of accrued but unpaid  dividends  hereunder,  are not delivered to or as
directed by the applicable  Holder by the


                                      -6-
<PAGE>

third  Trading Day after the  Conversion  Date,  the Holder shall be entitled by
written  notice to the  Company  at any time on or before  its  receipt  of such
certificate or certificates  thereafter,  to rescind such  conversion,  in which
event the Company shall  immediately  return the  certificates  representing the
shares of Preferred Stock tendered for conversion.

     (ii) If the  Company  fails to deliver to the Holder  such  certificate  or
certificates  pursuant to Section 5(b)(i),  including for purposes  hereof,  any
shares of Common Stock to be issued on the Conversion Date on account of accrued
but  unpaid  dividends  hereunder,  by the  third  (3rd)  Trading  Day after the
Conversion  Date,  the Company shall pay to such Holder,  in cash, as liquidated
damages and not as a penalty, $2,500 for each day after such third (3rd) Trading
Day until such certificates are delivered. Nothing herein shall limit a Holder's
right to pursue actual damages for the Company's failure to deliver certificates
representing  shares of Common Stock upon conversion within the period specified
herein and such Holder shall have the right to pursue all remedies  available to
it at law or in equity  including,  without  limitation,  a decree  of  specific
performance  and/or injunctive relief. The exercise of any such rights shall not
prohibit  the  Holders  from  seeking to enforce  damages  pursuant to any other
Section hereof or under applicable law.  Further,  if the Company shall not have
delivered  any cash due in  respect  of  conversions  of  Preferred  Stock or as
payment of dividends thereon by the third (3rd) Trading Day after the Conversion
Date,  the Holder  may, by notice to the  Company,  require the Company to issue
Underlying  Shares  pursuant to Section  5(c),  except that for such purpose the
Conversion Price applicable  thereto shall be the lesser of the Conversion Price
on the  Conversion  Date and the  Conversion  Price  on the date of such  Holder
demand.  Any such  Underlying  Shares will be subject to the  provision  of this
Section.

     (iii) In  addition to any other  rights  available  to the  Holder,  if the
Company fails to deliver to the Holder such certificate or certificates pursuant
to Section 5(b)(i), including for purposes hereof, any shares of Common Stock to
be issued on the  Conversion  Date on account of  accrued  but unpaid  dividends
hereunder, by the third Trading Day after the Conversion Date, and if after such
third (3rd) Trading Day the Holder  purchases (in an open market  transaction or
otherwise)  shares of Common Stock to deliver in  satisfaction of a sale by such
Holder of the Underlying Shares which the Holder anticipated receiving upon such
conversion  (a  "Buy-In"),  then the Company shall pay in cash to the Holder (in
addition to any  remedies  available  to or elected by the Holder) the amount by
which (x) the Holder's total purchase price (including brokerage commissions, if
any) for the  shares of Common  Stock so  purchased  exceeds  (y) the  aggregate
stated value of the shares of Preferred  Stock for which such conversion was not
timely  honored.  For example,  if the Holder  purchases  shares of Common Stock
having a total  purchase  price of $11,000 to cover a Buy-In with  respect to an
attempted  conversion  of  $10,000  aggregate  stated  value  of the  shares  of
Preferred  Stock,  the Company shall be required to pay the Holder  $1,000.  The
Holder shall provide the Company  written notice  indicating the amounts payable
to the Holder in respect of the Buy-In.

     (c)(i)  The  conversion  price  for each  share  of  Preferred  Stock  (the
"Conversion  Price") in effect on any Conversion Date shall be the lesser of (a)
$3.00 (the  "Initial  Conversion 


                                      -7-
<PAGE>

Price") and (b) 87.5% (the "Market  Conversion  Rate") multiplied by the average
of the five (5) lowest  daily Trade  Prices (as defined in Section 8) during the
twenty (20) Trading Days immediately  preceding the applicable  Conversion Date;
provided,  however,  that such twenty (20)  Trading Day period shall be extended
for the number of Trading  Days  during  such period in which (A) trading in the
Common Stock was suspended on the NASDAQ or on such  Subsequent  Market on which
the Common Stock is then listed, or (B) after the date declared effective by the
Commission,  the Underlying Securities  Registration Statement is not effective,
or (C) after the date  declared  effective  by the  Commission,  the  Prospectus
included in the Underlying Securities  Registration Statement may not be used by
the Holder for the resale of  Underlying  Shares;  provided  further,  except as
otherwise  specifically set forth herein, the Conversion Price shall not be less
than the Floor (as  defined in Section 8). The Floor (x) shall be  decreased  by
2.5% as of any Event Date (as  defined  below) and on each  monthly  anniversary
thereof  until the  applicable  Event  (as  defined  below) is cured,  (y) shall
simultaneously  be  adjusted  by  the  same  ratio  as  the  adjustments  to the
Conversion Price as a result of the provisions of Section 5(c)(ii)-(v),  and (z)
shall not apply in the event  that the Common  Stock is no longer  listed on the
NASDAQ (unless the Common Stock is immediately thereafter listed on a Subsequent
Market). If (a) an Underlying Securities  Registration Statement is not filed on
or prior to the Filing Date (if the  Company  files such  Underlying  Securities
Registration  Statement  without  affording the Holder the opportunity to review
and comment on the same as required by Section 3(a) of the  Registration  Rights
Agreement,  the Company shall not be deemed to have  satisfied this clause (a)),
or (b) the Company fails to file with the Commission a request for  acceleration
in accordance with Rule 12d1-2 promulgated under the Securities  Exchange Act of
1934, as amended,  within five (5) days of the date that the Company is notified
(orally  or in  writing,  whichever  is  earlier)  by  the  Commission  that  an
Underlying  Securities  Registration  Statement  will not be  "reviewed," or not
subject  to  further  review,  or (c)  the  Underlying  Securities  Registration
Statement  is not  declared  effective  by the  Commission  on or  prior  to the
Effectiveness  Date (as defined in the Registration  Rights  Agreement),  or (d)
such  Underlying  Securities  Registration  Statement is filed with and declared
effective  by the  Commission  but  thereafter  ceases to be effective as to all
Registrable Securities at any time prior to the expiration of the "Effectiveness
Period"  (as  defined  in the  Registration  Rights  Agreement),  without  being
succeeded  within  fifteen  (15)  days  by a  subsequent  Underlying  Securities
Registration  Statement filed with and declared effective by the Commission,  or
(e) trading in the Common Stock shall be delisted or  suspended  from trading on
the NASDAQ or on such Subsequent Market on which the Common Stock is then listed
for more than three Trading Days (which need not be consecutive days), or (f) if
the conversion rights of the Holders are suspended for any reason, or (g) if the
Company  is  required  to convene a  shareholders  meeting  pursuant  to Section
5(a)(iii) and fails to convene a meeting of shareholders within the time periods
specified  in Section  5(a)(iii)  or does so  convene a meeting of  shareholders
within such time period but fails to obtain Shareholder Approval at such meeting
(any such failure or breach being referred to as an "Event," and for purposes of
clauses  (a) and (c) the date on which such Event  occurs,  or for  purposes  of
clause  (b) the date on which  such  five (5) day  period  is  exceeded,  or for
purposes of clause (d) the date which such 15  day-period  is  exceeded,  or for
purposes  of clause (e) the date on which such three (3) Trading  Day-period  is
exceeded,  being referred to as "Event Date"),  the Initial Conversion Price and
the Market Conversion Rate shall be 


                                      -8-
<PAGE>

decreased by 2.5% on the Event Date and each monthly  anniversary  thereof until
the earlier to occur of the second  month  anniversary  after the Event Date and
such time as the applicable  Event is cured (i.e.,  by 2.5% as of the Event Date
and 5% as of the one month  anniversary  of such Event Date).  Commencing on the
second month  anniversary after the Event Date, the Holder shall have the option
to  either  (x)  require  further  cumulative  2.5%  decreases  to  the  Initial
Conversion  Price and the Market  Conversion Rate to continue or (y) require the
Company to pay to the Holder 2.5% of the  aggregate  Stated Values of the shares
of Preferred Stock then held by such Holder, in cash, as liquidated  damages and
not as a  penalty,  on the first day of each  monthly  anniversary  of the Event
Date,  until such time as the  applicable  Event is cured.  Any  decrease in the
Initial  Conversion Price or the Market Conversion Rate pursuant to this Section
shall  remain in effect  notwithstanding  the fact that the Event  causing  such
decrease has been subsequently  cured and further monthly decreases have ceased.
The  provisions  of this Section are not exclusive and shall in no way limit the
Company's obligations under the Registration Rights Agreement.

     (ii) If the Company,  at any time while any shares of  Preferred  Stock are
outstanding,  shall (a) pay a stock dividend or otherwise make a distribution or
distributions  on shares  of its  Junior  Securities  or pari  passu  securities
payable in shares of Common Stock,  (b) subdivide  outstanding  shares of Common
Stock into a larger number of shares,  (c) combine  outstanding shares of Common
Stock  into a smaller  number of  shares,  or (d) issue by  reclassification  of
shares of Common Stock any shares of capital  stock of the Company,  the Initial
Conversion  Price shall be multiplied by a fraction of which the numerator shall
be the number of shares of Common  Stock  outstanding  before  such event and of
which the denominator  shall be the number of shares of Common Stock outstanding
after such event.  Any adjustment  made pursuant to this Section  5(c)(ii) shall
become  effective  immediately  after the record date for the  determination  of
stockholders  entitled to receive such dividend or distribution and shall become
effective  immediately  after the effective  date in the case of a  subdivision,
combination or re-classification.

     (iii) If the Company,  at any time while any shares of Preferred  Stock are
outstanding,  shall issue  rights,  warrants or options to all holders of Common
Stock  entitling  them to subscribe for or purchase  shares of Common Stock at a
price  per  share  less  than the Per  Share  Market  Value at the  record  date
mentioned  below,  then the Initial  Conversion  Price shall be  multiplied by a
fraction,  the  numerator of which shall be the number of shares of Common Stock
outstanding  immediately  prior to the  issuance  of such  rights,  warrants  or
options,  plus the number of shares of Common Stock which the aggregate offering
price of the total number of shares so offered would  purchase at such Per Share
Market  Value,  and the  denominator  of which shall be the sum of the number of
shares of Common Stock  outstanding  immediately prior to such issuance plus the
number of shares of Common Stock  offered for  subscription  or  purchase.  Such
adjustment shall be made whenever such rights or warrants are issued,  and shall
become  effective  immediately  after the record date for the  determination  of
stockholders  entitled to receive  such rights or  warrants.  However,  upon the
expiration  of any right,  warrant or option to purchase  shares of Common Stock
the issuance of which resulted in an adjustment in the Conversion Price pursuant
to this Section 5(c)(iii), if any such right, warrant or option shall expire and
shall not 


                                      -9-
<PAGE>

have been exercised, the Conversion Price shall immediately upon such expiration
shall be recomputed  and effective  immediately  upon such  expiration  shall be
increased  to the  price  which it would  have been  (but  reflecting  any other
adjustments  in the  Conversion  Price made  pursuant to the  provisions of this
Section 5 upon the issuance of other rights or warrants)  had the  adjustment of
the Conversion Price made upon the issuance of such rights, warrants, or options
been made on the basis of offering for subscription or purchase only that number
of shares of Common Stock  actually  purchased upon the exercise of such rights,
warrants or options actually exercised.

     (iv) If the Company or any subsidiary  thereof,  as applicable with respect
to Common Stock  Equivalents (as defined below), at any time while any shares of
Preferred Stock are  outstanding,  shall issue shares of Common Stock or rights,
warrants,  options  or other  securities  or debt  that is  convertible  into or
exchangeable for shares of Common Stock ("Common Stock  Equivalents")  entitling
any Person to acquire  shares of Common Stock at a price per share less than the
Conversion  Price,  then the Conversion Price shall be multiplied by a fraction,
the numerator of which shall be the number of shares of Common Stock outstanding
immediately prior to the issuance of shares of Common Stock or such Common Stock
Equivalents  plus the number of shares of Common Stock which the offering  price
(including any applicable  exercise for any Common Stock  Equivalents)  for such
shares of  Common  Stock or  Common  Stock  Equivalents  would  purchase  at the
Conversion Price, and the denominator of which shall be the sum of the number of
shares of Common Stock  outstanding  immediately prior to such issuance plus the
number  of shares of Common  Stock so  issued or  issuable,  provided,  that for
purposes  hereof,  all shares of Common Stock that are issuable upon exercise or
exchange of Common Stock  Equivalents  shall be deemed  outstanding  immediately
after the issuance of such Common Stock  Equivalents.  Such adjustment  shall be
made  whenever  such  shares of Common  Stock or Common  Stock  Equivalents  are
issued;  provided,  however,  that no adjustments will be required in respect of
the granting of options or warrants to employees,  officers,  consultants (other
than placement  agents,  securities  bankers or finders) and  directors,  or the
issuance of shares upon the exercise thereof,  or upon exercise of any currently
outstanding Common Stock Equivalents.

     (v) If the  Company,  at any time  while  shares  of  Preferred  Stock  are
outstanding, shall distribute to all holders of Common Stock (and not to Holders
of  Preferred  Stock)  evidences  of its  indebtedness  or  assets  or rights or
warrants to subscribe for or purchase any security  (excluding those referred to
in Sections  5(c)(ii)-(iv) above), then in each such case the Initial Conversion
Price at which each share of Preferred  Stock shall  thereafter  be  convertible
shall be  determined  by  multiplying  the  Initial  Conversion  Price in effect
immediately  prior to the record date fixed for  determination  of  stockholders
entitled to receive  such  distribution  by a fraction of which the  denominator
shall be the Per Share Market Value of Common Stock  determined as of the record
date mentioned  above, and of which the numerator shall be such Per Share Market
Value of the Common Stock on such record date less the then fair market value at
such record date of the  portion of such assets or evidence of  indebtedness  so
distributed applicable to one outstanding share of Common Stock as determined by
the Board of Directors in good faith; provided,  however, that in the event of a
distribution  exceeding ten percent  (10%) of the net assets of the Company,  if
the  Holders of a majority  in  interest of the  Preferred  Stock  dispute  such
valuation, such fair market value shall be determined by a nationally recognized
or


                                      -10-
<PAGE>

major regional  investment banking firm or firm of independent  certified public
accountants  of  recognized  standing  (which  may be the  firm  that  regularly
examines the financial  statements of the Company) (an "Appraiser")  selected in
good faith by the Holders of a majority  in interest of the shares of  Preferred
Stock then outstanding;  and provided,  further, that the Company, after receipt
of the  determination  by such  Appraiser  shall  have the  right to  select  an
additional  Appraiser,  in good faith, in which case the fair market value shall
be equal to the average of the determinations by each such Appraiser.  In either
case the adjustments  shall be described in a statement  provided to the Holders
of  Preferred  Stock of the portion of assets or evidences  of  indebtedness  so
distributed or such subscription rights applicable to one share of Common Stock.
Such adjustment  shall be made whenever any such  distribution is made and shall
become effective immediately after the record date mentioned above.

     (vi) All  calculations  under this  Section 5 shall be made to the  nearest
cent or the nearest 1/100th of a share, as the case may be.

     (vii)  Whenever  the  Conversion  Price is  adjusted  pursuant  to  Section
5(c)(i),  (ii),  (iii),  (iv),  or (v) the Company  shall  promptly mail to each
Holder,  a notice setting forth the Conversion  Price after such  adjustment and
setting forth a brief statement of the facts requiring such adjustment.

     (viii)  In  case  of any  reclassification  of  the  Common  Stock,  or any
compulsory  share exchange  pursuant to which the Common Stock is converted into
other securities,  cash or property (other than compulsory share exchanges which
constitute Change of Control  Transactions),  the Holders of the Preferred Stock
then  outstanding  shall have the right  thereafter  to convert such shares only
into the shares of stock and other securities, cash and property receivable upon
or deemed to be held by holders of Common Stock following such  reclassification
or share exchange, and the Holders of the Preferred Stock shall be entitled upon
such event to receive such amount of securities, cash or property as a holder of
the number of shares of the Common  Stock of the Company  into which such shares
of  Preferred  Stock  could  have  been  converted  immediately  prior  to  such
reclassification  or share  exchange  would have been  entitled.  This provision
shall similarly apply to successive reclassifications or share exchanges.

     (ix)  If  (a)  the  Company   shall   declare  a  dividend  (or  any  other
distribution)  on its Common  Stock,  (b) the  Company  shall  declare a special
nonrecurring  cash  dividend on or a  redemption  of its Common  Stock,  (c) the
Company  shall  authorize the granting to all holders of the Common Stock rights
or warrants to  subscribe  for or  purchase  any shares of capital  stock of any
class or of any  rights,  (d) the  approval of any  stockholders  of the Company
shall be required in connection with any reclassification of the Common Stock of
the Company,  any  consolidation  or merger to which the Company is a party, any
sale or transfer of all or  substantially  all of the assets of the Company,  of
any  compulsory  share of exchange  whereby the Common Stock is  converted  into
other  securities,  cash or property,  or (e) the Company  shall  authorize  the
voluntary or involuntary  dissolution,  liquidation or winding up of the affairs
of the  Company;  then the  Company  shall  cause to be filed at each  office or
agency  maintained for the purpose of conversion 


                                      -11-
<PAGE>

of  Preferred  Stock,  and shall cause to be mailed to the Holders of  Preferred
Stock at their last  addresses  as they shall appear upon the stock books of the
Company,  at least 20 calendar days prior to the applicable  record or effective
date hereinafter  specified,  a notice stating (x) the date on which a record is
to be taken for the purpose of such dividend,  distribution,  redemption, rights
or warrants, or if a record is not to be taken, the date as of which the holders
of Common  Stock of  record  to be  entitled  to such  dividend,  distributions,
redemption,  rights or warrants  are to be  determined  or (y) the date on which
such reclassification,  consolidation,  merger, sale, transfer or share exchange
is  expected  to  become  effective  or  close,  and the  date as of which it is
expected  that  holders of Common  Stock of record shall be entitled to exchange
their shares of Common Stock for securities,  cash or other property deliverable
upon such  reclassification,  consolidation,  merger,  sale,  transfer  or share
exchange;  provided, however, that the failure to mail such notice or any defect
therein or in the mailing thereof shall not affect the validity of the corporate
action required to be specified in such notice.  Holders are entitled to convert
shares of Preferred  Stock during the 20-day period  commencing the date of such
notice to the effective date of the event triggering such notice.

     (x) If the Company (i) makes a public announcement that it intends to enter
into a Change  of  Control  Transaction  or (ii)  any  person,  group or  entity
(including  the Company,  but  excluding a Holder or any  affiliate of a Holder)
publicly announces a bona fide tender offer, exchange offer or other transaction
to purchase 33% or more of the Common Stock (such announcement being referred to
herein as a "Major  Announcement" and the date on which a Major  Announcement is
made,  the  "Announcement  Date"),  then,  in the event  that a Holder  seeks to
convert  shares of Preferred  Stock on or following the  Announcement  Date, the
Conversion  Price shall,  effective  upon the  Announcement  Date and continuing
through the earlier to occur of the consummation of the proposed  transaction or
tender offer,  exchange offer or other  transaction and the Abandonment Date (as
defined below),  be equal to the lower of (x) the average Per Share Market Value
on  the  five  Trading  Days  immediately  preceding  (but  not  including)  the
Announcement  Date and (y) the Conversion Price in effect on the Conversion Date
for such Preferred Stock.  "Abandonment Date" means with respect to any proposed
transaction  or tender offer,  exchange offer or other  transaction  for which a
public  announcement  as  contemplated by this paragraph has been made, the date
upon which the Company (in the case of clause (i) above) or the person, group or
entity (in the case of clause (ii) above) publicly  announces the termination or
abandonment  of the proposed  transaction  or tender  offer,  exchange  offer or
another transaction which caused this paragraph to become operative.

     (d) The  Company  covenants  that it will at all  times  reserve  and  keep
available out of its authorized and unissued Common Stock solely for the purpose
of issuance  upon  conversion  of  Preferred  Stock and payment of  dividends on
Preferred  Stock,  each as herein provided,  free from preemptive  rights or any
other actual  contingent  purchase  rights of persons  other than the Holders of
Preferred  Stock,  not less than such number of shares of Common  Stock as shall
(subject to any additional requirements of the Company as to reservation of such
shares set forth in the Purchase Agreement) be issuable (taking into account the
adjustments  and  restrictions  of  Section  5(a)  and  Section  5(c))  upon the
conversion of all outstanding shares of Preferred Stock and payment of dividends
hereunder.  The Company  covenants that all shares of 


                                      -12-
<PAGE>

Common Stock that shall be so issuable  shall,  upon issue,  be duly and validly
authorized,  issued and fully paid, nonassessable and freely tradeable,  subject
to the legend requirements of Section 3.1 (b) of the Purchase Agreement.

     (e) Upon a conversion  hereunder the Company shall not be required to issue
stock certificates  representing fractions of shares of Common Stock, but may if
otherwise  permitted,  make a cash payment in respect of any final fraction of a
share based on the Per Share  Market Value at such time.  If the Company  elects
not,  or is  unable,  to make  such a cash  payment,  the  Holder  of a share of
Preferred Stock shall be entitled to receive, in lieu of the final fraction of a
share, one whole share of Common Stock.

     (f) The issuance of  certificates  for shares of Common Stock on conversion
of Preferred  Stock shall be made without charge to the Holders  thereof for any
documentary  stamp or similar  taxes that may be payable in respect of the issue
or delivery of such certificate, provided that the Company shall not be required
to pay any tax that may be payable in respect of any  transfer  involved  in the
issuance and delivery of any such  certificate  upon  conversion in a name other
than that of the Holder of such shares of Preferred  Stock so converted  and the
Company  shall not be required to issue or deliver such  certificates  unless or
until the person or persons  requesting the issuance  thereof shall have paid to
the Company the amount of such tax or shall have established to the satisfaction
of the Company that such tax has been paid.

     (g)  Shares  of  Preferred  Stock  converted  into  Common  Stock  shall be
canceled. The Company may not reissue any shares of Preferred Stock.

     (h) Any  and all  notices  or  other  communications  or  deliveries  to be
provided by the Holders of the Preferred  Stock  hereunder,  including,  without
limitation, any Conversion Notice, shall be in writing and delivered personally,
by facsimile or sent by overnight delivery by a nationally  recognized overnight
courier  service,  addressed to the attention of the Chief Financial  Officer of
the Company at the facsimile  telephone number or address of the principal place
of business of the Company as set forth in the Purchase  Agreement.  Any and all
notices or other  communications  or  deliveries  to be  provided by the Company
hereunder shall be in writing and delivered personally,  by facsimile or sent by
a nationally  recognized overnight courier service,  addressed to each Holder of
Preferred  Stock at the  facsimile  telephone  number or address of such  Holder
appearing on the books of the Company,  or if no such facsimile telephone number
or address appears, at the principal place of business of the Holder. Any notice
or other  communication  or  deliveries  hereunder  shall be  deemed  given  and
effective  on the  earliest of (i) the date of  transmission,  if such notice or
communication  is delivered  via  facsimile at the  facsimile  telephone  number
specified in this Section prior to 8:00 p.m. (New York City Time), (ii) the date
after the date of transmission, if such notice or communication is delivered via
facsimile at the facsimile telephone number specified in this Section later than
8:00 p.m. (New York City Time) on any date and earlier than 11:59 p.m. (New York
City Time) on such date, (iii) upon receipt, if sent by a nationally  recognized
overnight courier service, or (iv) upon actual receipt by the party to whom such
notice is required to be given.

     Section 6. Optional Redemption.

     (a) The  Company  shall  have the  right,  exercisable  at any time upon 20
Trading  Days  notice (an  "Optional  Redemption  Notice") to the Holders of the
Preferred Stock given at any time after the Original Issue Date to redeem all or
any  portion of the shares of  Preferred  Stock which have not  previously  been
converted or redeemed,  at a price equal to the  Optional  Redemption  Price (as
defined  below).  The entire  Optional  Redemption  Price shall be paid in cash.
Holders  of  Preferred  Stock may  convert  (and the  Company  shall  honor such
conversions in accordance with the terms hereof) any shares of Preferred  Stock,
including  shares subject to an Optional  Redemption  Notice,  during the period
from the date  thereof  through  the 20th  Trading  Day after the  receipt of an
Optional Redemption Notice.

     (b) If any portion of the  Optional  Redemption  Price shall not be paid by
the Company by the 20th Trading Day after the delivery of an Optional Redemption
Notice,  interest  shall  accrue  thereon at the rate of 15% per annum until the
Optional  Redemption  Price  plus all such  interest  is paid in full  (any such
amount shall be paid as liquidated  damages and not as a penalty).  In addition,
if any portion of the Optional  Redemption  Price remains  unpaid after the date
due, the Holder of the Preferred  Stock subject to such redemption may elect, by
written notice to the Company given at any time thereafter, to either (i) demand
conversion in accordance  with the formula and the time frame therefor set forth
herein of all or any  portion  of the shares of  Preferred  Stock for which such
Optional Redemption Price, plus accrued liquidated damages thereof, has not been
paid in full (the  "Unpaid  Redemption  Shares"),  in which  event the Per Share
Market  Value for such shares  shall be the lower of the Per Share  Market Value
calculated on the date the Optional  Redemption Price was originally due and the
Per Share Market Value as of the Holder's written demand for conversion, or (ii)
invalidate ab initio such redemption,  notwithstanding anything herein contained
to the contrary. If the Holder elects option (i) above, the Company shall within
three (3) Trading Days of its receipt of such election deliver to the Holder the
shares of Common Stock issuable upon conversion of the Unpaid  Redemption Shares
subject to such Holder  conversion  demand and otherwise perform its obligations
hereunder with respect thereto;  or, if the Holder elects option (ii) above, the
Company shall  promptly,  and in any event not later than three (3) Trading Days
from receipt of Holder's  notice of such  election,  return to the Holder all of
the Unpaid Redemption Shares.

     (c) The "Optional  Redemption Price" shall equal the sum of (i) the product
of (A) the  number of  shares  of  Preferred  Stock to be  redeemed  and (B) the
product of (1) the average Per Share  Market Value for the five (5) Trading Days
immediately  preceding (x) the date of the Optional Redemption Notice or (y) the
date of  payment  in full  by the  Company  of the  Optional  Redemption  Price,
whichever is greater, and (2) the Conversion Ratio calculated on the date of the
Optional  Redemption  Notice,  and (ii) all other amounts,  costs,  expenses and
liquidated damages due in respect of such shares of Preferred Stock.

addition

right,  exercisable at the sole option of such Holder, to require the Company to

redemption  price,  in cash,  equal to the sum of (i) the  Mandatory  Redemption
Amount plus (ii) the product of (A) the number of  Underlying  Shares  issued in
respect of conversions or as payment of dividends hereunder and then held by the
Holder  and (B) the Per  Share  Market  Value on the  date  such  redemption  is
demanded or the date the redemption  price hereunder is paid in full,  whichever
is greater.  If the Company fails to pay the redemption  price hereunder in full
pursuant  to this  Section  within  seven  (7) days  after  the date of a demand
therefor,  the  Company  will pay  interest  thereon at a rate of 15% per annum,
accruing daily from such seventh day until the redemption  price,  plus all such

     Underlying  Securities  Registration  Statement  for more  than  seven  (7)
     Business Days (which need not be consecutive days);

          (iii) the  delisting of the Common  Stock,  or the  suspension  of the

     (whether or not such sale would constitute a Change of Control Transaction)
     or shall redeem more than a de minimis  number of shares of Common Stock or
     other Junior Securities (other than redemptions of Underlying Shares);

          (vi) an Event  shall not have been  cured to the  satisfaction  of the
     Holders  prior to the  expiration  of thirty  (30) days from the Event Date
     relating thereto;

          (vii) the Company shall fail for any reason to deliver the certificate

     2.1. Representations, Warranties and Agreements of the Company. The Company
hereby makes the following representations and warranties to the Purchaser:

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

          (b) The Company has the  requisite  corporate  power and  authority to
     enter into and to consummate the  transactions  contemplated by each of the
     Transaction   Documents,   and  otherwise  to  carry  out  its  obligations
     thereunder. The execution and delivery of each of the Transaction Documents
     by the Company and the consummation by it of the transactions  contemplated
     thereby have been duly  authorized by all  necessary  action on the part of
     the Company and no further  action is required by the Company.  Each of the
     Transaction  Documents  has been duly  executed  by the Company  and,  when
     delivered  (or  filed,  as the case may be) in  accordance  with the  terms
     hereof, will constitute the valid and binding obligation of the Company

                                      - 2 -
<PAGE>

     enforceable  against the Company in accordance with its terms.  The Company
     is  not  in  violation  of any of  the  provisions  of its  certificate  of
     incorporation, by-laws or other charter documents.

          (c) Capitalization.  The number of authorized,  issued and outstanding
     capital stock of the Company is set forth in Schedule 2.1(c).  No shares of
     Common  Stock are  entitled to  preemptive  or similar  rights,  nor is any
     holder of the Common Stock entitled to preemptive or similar rights arising
     out of any agreement or understanding  with the Company by virtue of any of
     the Transaction  Documents.  Except as disclosed in Schedule 2.1(c),  there
     are no outstanding options,  warrants, script rights to subscribe to, calls
     or  commitments  of any character  whatsoever  relating to, or, except as a
     result  of the  purchase  and sale of the  Shares,  securities,  rights  or
     obligations  convertible into or exchangeable for, or giving any Person any
     right to subscribe for or acquire any shares of Common Stock, or contracts,
     commitments, understandings, or arrangements by which the Company is or may
     become bound to issue  additional  shares of Common Stock, or securities or
     rights  convertible  or  exchangeable  into shares of Common Stock.  To the
     knowledge  of the  Company,  except as  specifically  disclosed  in the SEC
     Documents  (as  defined  below) or Schedule  2.1(c),  no Person or group of
     related  Persons  beneficially  owns (as determined  pursuant to Rule 13d-3
     promulgated  under the  Securities  Exchange  Act of 1934,  as amended (the
     "Exchange  Act"))  or has the  right to  acquire  by  agreement  with or by
     obligation binding upon the Company beneficial ownership of in excess of 5%
     of the  Common  Stock.  A  "Person"  means an  individual  or  corporation,
     partnership,  trust,  incorporated  or  unincorporated  association,  joint
     venture, limited liability company, joint stock company,  government (or an
     agency or subdivision thereof) or other entity of any kind.

          (d) Issuance of the Shares. The Shares are duly authorized, and, when
     issued and paid for in accordance  with the terms  hereof,  shall have been
     validly issued, fully paid and nonassessable,  free and clear of all liens,
     encumbrances  and  rights  of  first  refusal  of any  kind  (collectively,
     "Liens").  The Company has on the date hereof and will,  at all times while
     the Shares are outstanding, maintain an adequate reserve of duly authorized
     shares of Common Stock, reserved for issuance to the holders of the Shares,
     to enable it to perform its  conversion  and other  obligations  under this
     Agreement and the Certificate of  Designation.  Such number of reserved and
     available shares of Common Stock is not less than the sum of (i) subject to
     the  application  of any  floor to the  Conversion  Price  set forth in the
     Certificate  of  Designation,  200% of the number of shares of Common Stock
     which would be issuable  upon  conversion  in full of the Shares,  assuming
     such conversion  occurred on the Original Issue Date or the Filing Date (as
     defined in the  Registration  Rights  Agreement),  whichever yields a lower
     Conversion Price, and (ii) the number of shares Common Stock which would be
     issuable  upon payment of dividends on the Shares,  assuming  each Share is
     outstanding  for two years and all  dividends  are paid in shares of Common
     Stock.  The shares of Common Stock  issuable upon  conversion of the Shares
     and as payment of dividends thereon are collectively  referred to herein as

     others any rights of termination,  amendment,  acceleration or cancellation
     (with or without notice,  lapse of time or both) of, any agreement,  credit

     for the listing of the Underlying  Shares with the NASDAQ,  (iv) the filing
     of a Form D with the  Commission,  and (v) in all  other  cases  where  the
     failure to obtain such consent, waiver,  authorization or order, or to give
     such  notice or make such filing or  registration  could not have or result

     challenges  the  legality,   validity  or  enforceability  of  any  of  the
     Transaction  Documents or the Securities or (ii) could,  individually or in
     the aggregate, have or result in a Material Adverse Effect.

     warranties of the Purchaser  set forth in Sections  2.2(b)-(g),  the offer,
     issuance and sale of the Securities to the Purchaser as contemplated hereby
     are exempt from the  registration  requirements  of the  Securities  Act of
     1933, as amended (the "Securities Act"). Neither the Company nor any Person
     acting on its behalf  has taken any  action  could  subject  the  offering,
     issuance or sale of the Securities to the registration  requirements of the
     Securities Act.

          (j) SEC  Documents;  Financial  Statements.  The Company has filed all
     reports  required  to be filed  by it under  the  Exchange  Act,  including
     pursuant to Section 13(a) or 15(d) thereof, for the two years preceding the
     date hereof (or such  shorter  period as the Company was required by law to
     file such material) (the foregoing materials being collectively referred to
     herein as the "SEC  Documents"  and,  together  with the  Schedules to this
     Agreement the  "Disclosure  Materials") on a timely basis or has received a
     valid extension of such time of filing and has filed any such SEC Documents
     prior to the  expiration  of any  such  extension.  As of their  respective
     dates,  the SEC  Documents  complied  in all  material  respects  with  the
     requirements  of the  Securities Act and the Exchange Act and the rules and
     regulations of the Commission promulgated  thereunder,  and none of the SEC
     Documents, when filed, contained any untrue statement of a material fact or
     omitted to state a material fact required to be stated therein or necessary
     in order  to make the  statements  therein,  in light of the  circumstances
     under which they were made,  not  misleading.  All material  agreements  to
     which  the  Company  is a party or to which the  property  or assets of the
     Company are subject have been filed as exhibits to the SEC  Documents.  The
     financial statements of the Company included in the SEC Documents comply in
     all material respects with applicable accounting requirements and the rules
     and  regulations of the Commission with respect thereto as in effect at the
     time of filing.  Such financial  statements were prepared by the Company in
     accordance  with  generally  accepted  accounting  principles  applied on a
     consistent  basis ("GAAP")  during the periods  involved,  except as may be
     otherwise specified in such financial  statements or the notes thereto, and
     fairly  present in all  material  respects  the  financial  position of the
     Company as of and for the dates thereof and the results of  operations  and
     cash flows for the periods  then ended,  subject,  in the case of unaudited
     statements,  to  normal,  immaterial,   year-end  audit  adjustments.   The
     financial statements for the years ended December 31, 1996 and December 31,
     1997 were audited and reported upon by the Company's  independent  auditors
     in accordance with generally accepted accounting standards.  Since December
     31, 1997, except as specifically disclosed in the SEC Documents,  (a) there
     has been no event, occurrence or development that could have or result in a
     Material  Adverse Effect,  (b) the Company has not incurred any liabilities
     (contingent  or  otherwise)  other  than (x)  liabilities  incurred  in the
     ordinary  course  of  business   consistent  with  past  practice  and  (y)
     liabilities  not  required  to be  reflected  in  the  Company's  financial
     statements  pursuant to GAAP, (c) the Company has not altered its method of
     accounting  or the  identity  of its  auditors  and (d) the Company has not
     declared or made any payment or  distribution  of cash or other property to
     its  stockholders  or officers or directors  (other than in compliance with
     existing  Company stock option plans) with respect to its capital stock, or
     purchased,  redeemed  (or made any  agreements  to  purchase or redeem) any
     shares of its capital  stock.  The  Company  last filed  audited  financial
     statements  with the Commission on March 31, 1998, and has not received any
     comments from the Commission in respect thereof.

     company"  within the  meaning of the  Investment  Company  Act of 1940,  as
     amended.

          (l) Certain  Fees.  Except for certain  fees payable by the Company to

     shall have no  obligation  with  respect to any fees or with respect to any
     claims  made  by  or  on  behalf  of  other  Persons  for  fees  of a  type
     contemplated  in  this  Section  that  may be due in  connection  with  the
     transactions  contemplated by this  Agreement.  The Company shall indemnify
     and hold  harmless  the  Purchaser,  its  employees,  officers,  directors,
     agents, and partners, and their respective Affiliates, from and against all
     claims,  losses,  damages,  costs  (including the costs of preparation  and
     attorney's  fees) and  expenses  suffered in respect of any such claimed or
     existing fees, as such fees and expenses are incurred.

          (m) Solicitation Materials.  Neither the Company nor any Person acting
     on the  Company's  behalf has (i)  distributed  any  offering  materials in
     connection  with the  offering  and sale of the  Securities  other than the
     Disclosure  Materials,  or (ii)  solicited  any  offer  to buy or sell  the
     Securities by means of any form of general solicitation or advertising.

          (n)  Form  S-3  Eligibility.  The  Company  is  eligible  to  register
     securities for resale with the Commission under Form S-3 promulgated  under
     the Securities Act.

     any Person  other than the  Purchaser  other than with the  specific  prior
     written consent of the Purchaser.

          (p) Seniority.  No class of equity securities of the Company is senior
     to the Shares in right of payment, whether upon liquidation or dissolution,
     or otherwise.

          (q) Patents and Trademarks. The Company has, or has rights to use, all
     patents, patent applications,  trademarks, trademark applications,  service
     marks,  trade names,  copyrights,  licenses and rights  (collectively,  the
     "Intellectual  Property Rights") which are necessary or material for use in
     connection with its business, and which the failure to so have would have a
     Material  Adverse  Effect.  To the best knowledge of the Company,  all such
     Intellectual  Property  Rights  are  enforceable  and there is no  existing
     infringement by another Person of any of the Intellectual Property Rights.

          (r) Listing and  Maintenance  Requirements  Compliance.  Except as set
     forth on Schedule  2.1(r),  the Company has not in the two years  preceding
     the date hereof  received  notice  (written or oral) from the NASDAQ or any
     other stock exchange,  market or trading facility on which the Common Stock
     is or has been  listed (or on which it has been  quoted) to the effect that
     the  Company  is  not  in  compliance   with  the  listing  or  maintenance
     requirements  of such  exchange or market.  The Company  has  provided  the
     Purchaser with complete copies of all notices described on Schedule 2.1(r).
     The Company is in compliance with all such maintenance requirements.

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

          (t)  Regulatory  Permits.  The  Company  possesses  all  certificates,
     authorizations  and permits  issued by the  appropriate  Federal,  state or
     foreign  regulatory  authorities  necessary  to  conduct  their  respective
     businesses as described in the SEC  Documents,  except where the failure to
     possess such permits could not,  individually or in the aggregate,  have or
     result in a Material Adverse Effect ("Material  Permits"),  and the Company
     has not received any notice of  proceedings  relating to the  revocation or
     modification of any Material Permit.

          (u)  Disclosure.  The Company  confirms  that it has not  provided the
     Purchaser or its agents or counsel with any information that constitutes or
     might constitute material non-public  information.  The Company understands
     and  confirms  that  the  Purchaser  shall  be  relying  on  the  foregoing
     representations in effecting transactions in securities of the Company. All
     disclosure  provided to the Purchaser  regarding the Company,  its business
     and the transactions  contemplated hereby,  including the Schedules to this
     Agreement,  furnished  by or on behalf of the  Company are true and correct
     and do not contain any untrue statement of a material fact or omit to state
     any material fact necessary in order to make the  statements  made therein,
     in light of the circumstances under which they were made, not misleading.

     2.2 Representations  and Warranties of the Purchaser.  The Purchaser hereby
represents and warrants to the Company as follows:

          (a)  Organization;  Authority.  The  Purchaser is a  corporation  duly
     organized,  validly  existing  and in good  standing  under the laws of the
     jurisdiction of its  incorporation  with the requisite  corporate power and
     authority, to enter into and to consummate the transactions contemplated by
     the  Transaction  Documents  and  otherwise  to carry  out its  obligations
     thereunder.  The purchase by the Purchaser of the Securities  hereunder has
     been duly authorized by all necessary  action on the part of the Purchaser.
     Each of this Agreement,  the  Registration  Rights Agreement and the Escrow
     Agreement  has been  duly  executed  and  delivered  by the  Purchaser  and
     constitutes  the valid and legally  binding  obligation  of the  Purchaser,
     enforceable against it in accordance with its terms.

          (b) Investment  Intent.  The Purchaser is acquiring the Securities for
     its own account for investment  purposes only and not with a view to or for
     distributing  or reselling such  Securities or any part thereof or interest
     therein,  without prejudice,  however, to the Purchaser's right, subject to
     the provisions of this Agreement and the Registration Rights Agreement,  at
     all  times  to  sell  or  otherwise  dispose  of all or any  part  of  such
     Securities  pursuant  to an  effective  registration  statement  under  the
     Securities Act and in compliance with applicable  state  securities laws or
     under an exemption from such registration.

          (c)  Purchaser  Status.  At the time the  Purchaser  was  offered  the
     Shares, it was, and at the date hereof, it is, an "accredited  investor" as
     defined in Rule 501(a) under the Securities Act.

          (d)  Experience  of the  Purchaser.  The  Purchaser  either  alone  or
     together with its representatives,  has such knowledge,  sophistication and
     experience  in  business  and  financial  matters  so as to be  capable  of
     evaluating  the  merits  and  risks of the  prospective  investment  in the
     Securities, and has so evaluated the merits and risks of such investment.

          (e) Ability of the Purchaser to Bear Risk of Investment. The Purchaser
     is able to bear the economic risk of an investment in the  Securities  and,
     at the present time, is able to afford a complete loss of such investment.

          (f) Access to Information.  The Purchaser  acknowledges receipt of the
     Disclosure  Materials  and further  acknowledges  that it has  reviewed the
     Disclosure  Materials and has been afforded (i) the opportunity to ask such
     questions  as it has deemed  necessary  of, and to  receive  answers  from,
     representatives  of the Company  concerning the terms and conditions of the
     offering of the  Securities  and the merits and risks of  investing  in the
     Securities;  (ii) access to information about the Company and the Company's
     financial   condition,   results  of  operations,   business,   properties,
     management   and  prospects   sufficient  to  enable  it  to  evaluate  its
     investment; and (iii) the opportunity to obtain such additional information
     which the Company possesses or can acquire without  unreasonable  effort or
     expense  that is  necessary to make an informed  investment  decision  with
     respect to the  investment and to verify the accuracy and  completeness  of
     the information contained in the Disclosure Materials.

          (g) General  Solicitation.  The Purchaser is not purchasing the Shares
     as a result of or subsequent to any advertisement, article, notice or other
     communication  published  in any  newspaper,  magazine or similar  media or
     broadcast over television or radio or presented at any seminar.

          (h) Certain  Trading  Activities.  On the date of this  Agreement  the
     Purchaser does not have a short position on any shares of Common Stock, and
     from the date of this  Agreement to the Closing Date the Purchaser will not
     establish a short position in the Common Stock.

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

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

                                   ARTICLE III
                         OTHER AGREEMENTS OF THE PARTIES

     3.1 Transfer Restrictions.  (a) Securities may only be disposed of pursuant
to an effective  registration statement under the Securities Act, to the Company
or pursuant to an available  exemption  from or in a transaction  not subject to
the  registration  requirements  of the Securities  Act. In connection  with any
transfer  of  Securities  other  than  pursuant  to  an  effective  registration
statement or to the Company,  except as otherwise set forth herein,  the Company
may  require  the  transferor  thereof to  provide to the  Company an opinion of
counsel  selected by the  transferor,  the form and  substance of which  opinion
shall be  reasonably  satisfactory  to the  Company,  to the  effect  that  such
transfer does not require registration under the Securities Act. Notwithstanding
the  foregoing,  the  Company  hereby  consents to and agrees to register on the
books of the  Company  and with any  transfer  agent for the  securities  of the
Company any  transfer of  Securities  by the  Purchaser  to an  Affiliate of the
Purchaser  or to a fund under  common  management  with the  Purchaser,  and any
transfer among any such Affiliates or funds,  provided that transferee certifies
to the Company  that it is an  "accredited  investor"  as defined in Rule 501(a)
under the  Securities  Act and that it is acquiring  the  Securities  solely for
investment  purposes.  Any such transferee shall agree in writing to be bound by
the terms of this Agreement and shall have the rights of a Purchaser  under this
Agreement and the Registration Rights Agreement.

     (b) The Purchaser agrees to the imprinting,  so long as is required by this
Section 3.1(b), of the following legend on the Securities:

               NEITHER  THESE  SECURITIES  NOR THE  SECURITIES  INTO WHICH THESE
          SECURITIES ARE  CONVERTIBLE  HAVE BEEN  REGISTERED WITH THE SECURITIES
          AND EXCHANGE  COMMISSION OR THE SECURITIES  COMMISSION OF ANY STATE IN
          RELIANCE UPON AN EXEMPTION FROM REGISTRATION  UNDER THE SECURITIES ACT
          OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND, ACCORDINGLY,  MAY NOT
          BE  OFFERED  OR SOLD  EXCEPT  PURSUANT  TO AN  EFFECTIVE  REGISTRATION
          STATEMENT  UNDER  THE  SECURITIES  ACT  OR  PURSUANT  TO AN  AVAILABLE
          EXEMPTION FROM, OR IN A TRANSACTION  NOT SUBJECT TO, THE  REGISTRATION
          REQUIREMENTS  OF THE SECURITIES ACT AND IN ACCORDANCE  WITH APPLICABLE
          STATE SECURITIES LAWS.

               THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO CERTAIN
          RESTRICTIONS ON CONVERSION SET FORTH IN A CONVERTIBLE  PREFERRED STOCK
          PURCHASE AGREEMENT, DATED AS OF MAY 29, 1998, BETWEEN COMPOSITECH LTD.
          (THE  "COMPANY")  AND  THE  ORIGINAL  HOLDER  HEREOF.  A COPY  OF THAT
          AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICE OF THE COMPANY.

     Underlying  Shares  shall not  contain  the legend set forth  above nor any
other legend if the conversion of Shares, the payment of dividends  thereon,  or
other  issuances  of  Underlying  Shares  as  contemplated   hereby  or  by  the
Certificate  of  Designation  occurs at any time while an Underlying  Securities
Registration  Statement is effective  under the  Securities Act or, in the event

                                     - 9 -
<PAGE>


there is not an effective Underlying Securities  Registration  Statement at such
time,  if in the opinion of counsel to the Company  such legend is not  required
under  applicable   requirements  of  the  Securities  Act  (including  judicial
interpretations and pronouncements  issued by the staff of the Commission).  The
Company  shall  cause its  counsel to issue the legal  opinion  included  in the
Transfer Agent  Instructions to the Company's transfer agent on the day that the
Underlying  Securities  Registration  Statement  is  declared  effective  by the
Commission. The Company agrees that it will provide the Purchaser, upon request,
with a certificate or certificates  representing  Underlying  Shares,  free from
such legend at such time as such  legend is no longer  required  hereunder.  The
Company may not make any  notation on its  records or give  instructions  to any
transfer  agent of the Company  which enlarge the  restrictions  of transfer set
forth in this Section.

     3.2 Acknowledgment of Dilution.  The Company acknowledges that the issuance
of the Underlying  Shares upon conversion of the Shares and payment of dividends
thereon in  accordance  with the terms of the  Certificate  of  Designation  may
result in dilution of the outstanding shares of Common Stock, which dilution may
be substantial under certain market conditions. The Company further acknowledges
that its obligation to issue Underlying Shares upon conversion of the Shares and
payment of dividends  thereon in accordance with the terms of the Certificate of
Designation is unconditional and absolute,  subject to the limitations set forth
herein  and in the  Certificate  of  Designation  (including  any  floor  to the
Conversion  Price  set  forth  therein),  regardless  of the  effect of any such
dilution.

     3.3 Furnishing of  Information.  As long as the Purchaser owns  Securities,
the Company  covenants to timely file (or obtain  extensions in respect  thereof
and file within the applicable grace period) all reports required to be filed by
the  Company  after the date hereof  pursuant  to Section  13(a) or 15(d) of the
Exchange Act. As long as the Purchaser  owns  Securities,  if the Company is not
required to file reports pursuant to such sections,  it will prepare and furnish
to the  Purchaser and make  publicly  available in  accordance  with Rule 144(c)
promulgated under the Securities Act annual and quarterly financial  statements,
together with a discussion and analysis of such financial statements in form and
substance  substantially similar to those that would otherwise be required to be
included in reports  required by Section  13(a) or 15(d) of the Exchange Act, as
well as any other  information  required  thereby,  in the time period that such
filings  would have been  required to have been made under the Exchange Act. The
Company further covenants that it will take such further action as any holder of
Securities may reasonably request,  all to the extent required from time to time
to enable such Person to sell Underlying Shares without  registration  under the
Securities  Act within the  limitation  of the  exemptions  provided by Rule 144
promulgated  under the Securities  Act,  including the legal opinion  referenced
above in this  Section.  Upon the request of any such Person,  the Company shall
deliver to such Person a written  certification of a duly authorized  officer as
to whether it has complied with such requirements.

     3.4 Blue Sky Laws. In accordance with the  Registration  Rights  Agreement,
the Company  shall  qualify or exempt the  issuance  and sale of the  Underlying
Shares  under  the  securities  or Blue  Sky laws of such  jurisdictions  as the
Purchaser  may  reasonably  request and shall  continue  such  qualification  or
exemption at all times until the Purchaser  notifies the Company in writing that
it no longer owns Securities;  provided,  however, that the Company shall not be
required in connection  therewith to qualify as a foreign  corporation it is not
now so qualified or to take any action that

                                     - 10 -
<PAGE>

would subject the Company to general service of process in any such jurisdiction
where it is not then subject.

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

     3.6 Increase in Authorized  Shares.  At such times as the Company would be,
if a notice of  conversion  were to be  delivered on such date,  precluded  from
converting  200% of the  Shares  outstanding  (and  paying any earned and unpaid
dividends in respect thereof in shares of Common Stock) that remain  unconverted
at such date (subject to the  application of any floor to the  Conversion  Price
that  may  be  set  forth  in  the  Certificate  of  Designation)   due  to  the
unavailability  of a sufficient  number of shares of authorized  but unissued or
reserved Common Stock, the Board of Directors of the Company shall promptly (and
in any case,  within 30  Business  Days from such date)  prepare and mail to the
stockholders of the Company proxy materials  requesting  authorization  to amend
the Company's  Certificate of  Incorporation to increase the number of shares of
Common Stock which the Company is authorized to issue to at least such number of
shares as  reasonably  requested  by the  Purchaser in order to provide for such
number of authorized  and unissued  shares of Common Stock to enable the Company
to comply with its conversion and reservation of shares obligations as set forth
in this Agreement and the Certificate of Designation  (the sum of (x) the number
of shares of Common  Stock then  authorized,  (y) the number of shares of Common
Stock then outstanding plus all shares of Common Stock issuable upon exercise of
all outstanding options, warrants and convertible instruments,  and (z) (subject
to the application of any floor to the Conversion Price that may be set forth in
the Certificate of Designation)  200% of the number of Underlying  Shares as are
then  issuable  upon a  conversion  in  full of all  Shares  and as  payment  of
dividends thereon,  shall be a reasonable number). In connection therewith,  the
Board of Directors shall (a) adopt proper resolutions authorizing such increase,
(b)  recommend to and otherwise use its best efforts to promptly and duly obtain
stockholder  approval to carry out such  resolutions (and hold a special meeting
of the  stockholders  no later  than the 60th day  after  delivery  of the proxy
materials  relating to such meeting) and (c) within 5 business Days of obtaining
such stockholder  authorization,  file an appropriate amendment to the Company's
Certificate of Incorporation to evidence such increase.

     3.7 Listing and Reservation of Underlying Shares. (a) The Company shall (i)
not later than the 20th day following  the Closing  Date,  prepare and file with
the  NASDAQ  (as well as any other  national  securities  exchange  or market or
trading  or  quotation  facility  on which the Common  Stock is then  listed) an
additional  shares  listing  application  covering  a number of shares of Common
Stock  which is at least  equal to the number of shares  required to be reserved
pursuant  to Section  2.1(d),  (ii) take all steps  necessary  to cause the such
shares  to be  approved  for  listing  in the  NASDAQ  (as well as on any  other
national securities exchange or market or trading or quotation facility on which
the Common  Stock is then  listed)  as soon as  possible  thereafter,  and (iii)
provide  to the  Purchaser  evidence  of such  listing,  and the  Company  shall
maintain the listing of its Common Stock  thereon.  If the number of  Underlying
Shares as are  issuable  upon  conversion  in full of the number of Shares  then
outstanding  and as payment of  dividends  thereon  exceeds 85% of the number of
Underlying

                                     - 11 -
<PAGE>

Shares  previously  listed on account  thereof  with NASDAQ (and other  required
exchanges),  the Company shall take the necessary  actions to immediately list a
number of Underlying  Shares as equals 200% of the number of  Underlying  Shares
then issuable upon conversion of the Shares and as payment of dividends  thereon
(subject to the application of any floor to the Conversion Price that may be set
forth in the Certificate of Designation).

     (b) The Company shall  maintain a reserve of Common Stock for issuance upon
conversion  of the Shares  (and for  payment of  dividends  thereon in shares of
Common  Stock) in such amount as may be required to perform its  obligations  in
full under the  Transaction  Documents,  which reserve shall include a number of
shares of Common Stock equal to (subject to the  application of any floor to the
Conversion  Price that may be set forth in the  Certificate of  Designation)  no
less than two times the  number of shares of Common  Stock as would be  issuable
upon conversion in full of the Shares and upon payment of dividends thereon.

     3.8  Purchaser  Ownership  of Common  Stock.  The  Purchaser  agrees not to
convert  Shares to the extent  such  conversion  would  result in the  Purchaser
beneficially  owning (as  determined  in  accordance  with Section  13(d) of the
Exchange  Act and the rules  thereunder)  in  excess of 4.999% of the  shares of
Common  Stock then  issued  and  outstanding,  including  shares  issuable  upon
conversion  of the  Shares  held by such  Purchaser  after  application  of this
Section.  To the extent that the limitation  contained in this Section  applies,
the  determination  of whether  Shares are  convertible  (in  relation  to other
securities owned by a Purchaser) and of which Shares are convertible shall be in
the  sole  discretion  of the  Purchaser,  and  the  submission  of  Shares  for
conversion shall be deemed to be such Purchaser's  determination of whether such
Shares are  convertible (in relation to other  securities  owned by a Purchaser)
and of which  portion of such Shares are  convertible,  in each case  subject to
such aggregate percentage  limitation,  and the Company shall have no obligation
to verify or confirm  the  accuracy  of such  determination.  Nothing  contained
herein shall be deemed to restrict the right of the Purchaser to convert  Shares
at such time as such conversion will not violate the provisions of this Section.
The  provisions  of this  Section will not apply to any  conversion  pursuant to
Section  5(a)(ii) of the  Certificate of  Designation,  and may be waived by the
Purchaser  upon not less  than 75 days  prior  notice  to the  Company,  and the
provisions  of this  Section  shall  continue  to apply  until such 75th day (or
later, if stated in the notice of waiver).

     3.9 Conversion  Procedures.  The Transfer Agent Instructions and Conversion
Notice (as defined in Exhibit A) set forth the totality of the  procedures  with
respect to the conversion of the Shares, including the form of legal opinion, if
necessary, that shall be rendered to the Company's transfer agent and such other
information  and  instructions  as may be  reasonably  necessary  to enable  the
Purchaser  to  convert  its  Shares  as   contemplated  in  the  Certificate  of
Designation.

     3.10 Notice of Breaches.  (a) Each of the Company and the  Purchaser  shall
give  prompt   written  notice  to  the  other  of  any  breach  by  it  of  any
representation,  warranty  or  other  agreement  contained  in  any  Transaction
Document,  as well as any events or  occurrences  arising  after the date hereof
which  would  reasonably  be likely to cause any  representation  or warranty or
other  agreement  of such  party,  as the case may be,  contained  therein to be
incorrect or breached.  However,  no disclosure by either party pursuant to this
Section  shall be deemed to cure any breach of any  representation,  warranty or
other agreement contained in any Transaction Document.

                                     - 12 -

     (b)  Notwithstanding  the generality of Section 3.10(a),  the Company shall
promptly  notify the Purchaser of any notice or claim  (written or oral) that it
receives from any lender of the Company to the effect that the  consummation  of
the  transactions  contemplated by the Transaction  Documents  violates or would
violate any  written  agreement  or  understanding  between  such lender and the
Company,  and the Company shall promptly  furnish by facsimile to the holders of
the Shares a copy of any  written  statement  in support of or  relating to such
claim or notice.

     3.11  Conversion  Obligations  of the  Company.  The  Company  shall  honor
conversions of the Shares and shall deliver Underlying Shares in accordance with
the  terms,  conditions  and  time  periods  set  forth  in the  Certificate  of

or warrants to employees,  officers,  consultants  (other than placement agents,

Placement, which Subsequent Placement Notice shall describe in reasonable detail

acceptable  documentation,  financing to the Company on substantially  the terms
set forth in the Subsequent Placement Notice. If Encore shall fail to notify the
Company  of its  intention  to enter  into such  negotiations  within  such time
period, the Company may effect the Subsequent  Placement  substantially upon the
terms  and to the  Persons  (or  Affiliates  of such  Persons)  set forth in the
Subsequent  Placement  Notice;  provided,  that the Company shall provide Encore
with a second Subsequent Placement Notice, and Encore shall again have the right
of first  refusal  set forth  above in this  paragraph  (a),  if the  Subsequent

Notice within thirty (30) Business Days after the date of the initial Subsequent

promulgated under the Securities Act, or (ii) register for resale any securities

either party to exercise any right  hereunder in any manner  impair the exercise
of any such right accruing to it thereafter.

understood  that both parties need not sign the same  counterpart.  In the event
that any signature is delivered by facsimile transmission,  such signature shall

in issuing any press releases or otherwise  making public  statements or filings
and other  communications  with the Commission or any regulatory agency or stock
market or trading facility with respect to the transactions  contemplated hereby
and neither party shall issue any such press release or otherwise  make any such
public  statement,  filings or other  communications  without the prior  written
consent  of the other,  which  consent  shall not be  unreasonably  withheld  or
delayed,  except that no prior consent  shall be required if such  disclosure is
required by law or by the Commission or the Nasdaq Stock Market (as the case may
be), in which such case the disclosing  party shall provide the other party with
prior  notice  of  such  public  statement,   filing  or  other   communication.
Notwithstanding the foregoing,  the Company shall not publicly disclose the name
of the  Purchaser or Encore,  or include the name of the  Purchaser or Encore in
any filing with the Commission,  or any regulatory  agency,  trading facility or
stock market without the prior written  consent of Encore,  except to the extent
such disclosure (but not any disclosure as to the controlling  Persons  thereof)
is required by law, in which case the Company  shall  provide the  Purchaser and
Encore with prior notice of such disclosure.

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

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

contemplated  in Section 2(a),  then the Company shall have fifteen (15) days to
file such  additional  Registration  Statements  after notice of the requirement
thereof,  which the  Holders  may give at such time when the number of shares of
Common Stock as are issuable upon  conversion of Preferred  Stock and the number
of shares of Common  Stock  issuable as  dividends  thereon,  exceeds 85% of the
number of shares of Common Stock to be  registered in a  Registration  Statement
hereunder.

additional  registration  statements contemplated by Section 2(a), including (in

Holders will be reimbursed by the Company pursuant to Section 4.

in connection  with which  securities of the Company are sold to an  underwriter
for reoffering to the public pursuant to an effective registration statement.

     2. Shelf Registration

     (a) On or prior to the Filing Date, the Company shall prepare and file with
the  Commission  a  "Shelf"  Registration  Statement  covering  all  Registrable
Securities  for an offering to be made on a  continuous  basis  pursuant to Rule
415. The  Registration  Statement shall be on Form S-3 (or if the Company is not
then eligible to register for resale the Registrable  Securities on Form S-3, in
which case such registration shall be on another  appropriate form in accordance
herewith).  The  Registration  Statement shall state, to the extent permitted by
Rule 416,  that it also  covers  such  indeterminate  number of shares of Common
Stock as may be required to effect  conversion of the Preferred Stock to prevent
dilution  resulting from stock splits,  stock dividends or similar events, or by
reason of changes in the  Conversion  Price in accordance  with the terms of the
Certificate of Designation (as defined in the Purchase  Agreement).  The Company
shall use its best  efforts to cause the  Registration  Statement to be declared
effective  under the  Securities  Act as promptly  as possible  after the filing
thereof,  but in any event prior to the  Effectiveness  Date,  and shall use its
best efforts to keep such Registration  Statement  continuously  effective under
the  Securities Act until the date which is three years after the date that such
Registration  Statement is declared  effective by the Commission or such earlier
date when all Registrable Securities covered by such Registration Statement have
been sold or may be sold without volume restrictions  pursuant to Rule 144(k) as
determined by the counsel to the Company pursuant to a written opinion letter to
such effect,  addressed  and  acceptable to the  Company's  transfer  agent (the
"Effectiveness Period"), provided, however, that the Company shall not be deemed
to have  used its best  efforts  to keep the  Registration  Statement  effective
during the  Effectiveness  Period if it voluntarily  takes any action that would
result in the Holders not being able to sell the Registrable  Securities covered
by such  Registration  Statement during the  Effectiveness  Period,  unless such
action  is  required   under   applicable   law  or  the  Company  has  filed  a
post-effective  amendment to the  Registration  Statement and the Commission has
not declared it effective.

     (b) If the Holders of a majority of the Registrable Securities so elect, an
offering of Registrable Securities pursuant to the Registration Statement may be
effected in the form of an  Underwritten  Offering.  In such event,  and, if the
managing  underwriters  advise the Company and such  Holders in writing  that in
their opinion the amount of Registrable  Securities  proposed to be sold in such
Underwritten Offering exceeds the amount of Registrable  Securities which can be
sold in such Underwritten Offering, there shall be included in such Underwritten
Offering the amount of such Registrable  Securities which in the opinion of such
managing  underwriters  can be sold, and such amount shall be allocated pro rata
among the Holders proposing to sell Registrable  Securities in such Underwritten
Offering.



                                      -4-
<PAGE>

     (c) If any of the Registrable  Securities are to be sold in an Underwritten
Offering,  the investment  banker in interest that will  administer the offering
will be  selected by the  Holders of a majority  of the  Registrable  Securities
included in such  offering  upon  consultation  with the Company.  No Holder may
participate in any Underwritten Offering hereunder unless such Holder (i) agrees
to sell its  Registrable  Securities on the basis  provided in any  underwriting
agreements   approved  by  the  Persons  entitled   hereunder  to  approve  such
arrangements  and (ii)  completes  and  executes all  questionnaires,  powers of
attorney,  indemnities,  underwriting  agreements and other  documents  required
under the terms of such arrangements.

     3. Registration Procedures

     In connection with the Company's registration  obligations  hereunder,  the
Company shall:

     (a) Prepare and file with the  Commission on or prior to the Filing Date, a
Registration  Statement  on Form S-3 (or if the Company is not then  eligible to
register for resale the  Registrable  Securities  on Form S-3 such  registration
shall be on another appropriate form in accordance  herewith,  or, in connection
with an  Underwritten  Offering  hereunder,  such  other  form  agreed to by the
Company and by the Holders of  Registrable  Securities)  in accordance  with the
method or methods of distribution thereof as specified by the Holders (except if
otherwise  directed by the  Holders),  and cause the  Registration  Statement to
become  effective and remain effective as provided  herein;  provided,  however,
that  not  less  than  five  (5)  Business  Days  prior  to  the  filing  of the
Registration  Statement or any related Prospectus or any amendment or supplement
thereto  (including  any  document  that would be  incorporated  or deemed to be
incorporated  therein by  reference),  the  Company  shall,  (i)  furnish to the
Holders, their Special Counsel and any managing underwriters, copies of all such
documents  proposed to be filed,  which documents (other than those incorporated
or deemed to be incorporated by reference) will be subject to the review of such
Holders,  their Special Counsel and such managing  underwriters,  and (ii) cause
its officers and directors, counsel and independent certified public accountants
to respond to such inquiries as shall be necessary, in the reasonable opinion of
respective  counsel  to  such  Holders  and  such  underwriters,  to  conduct  a
reasonable  investigation  within the meaning of the Securities Act. The Company
shall  not  file  the  Registration  Statement  or any  such  Prospectus  or any
amendments  or  supplements  thereto to which the  Holders of a majority  of the
Registrable  Securities,  their Special Counsel,  or any managing  underwriters,
shall reasonably object on a timely basis.

     (b) (i) Prepare and file with the  Commission  such  amendments,  including
post-effective  amendments, to the Registration Statement as may be necessary to
keep the  Registration  Statement  continuously  effective as to the  applicable
Registrable  Securities for the  Effectiveness  Period and prepare and file with
the Commission such additional  Registration Statements in order to register for
resale under the Securities Act all of the  Registrable  Securities;  (ii) cause
the related Prospectus to be amended or supplemented by any required  Prospectus
supplement,  and as so  supplemented or amended to be filed pursuant to Rule 424
(or any similar  provisions then in force) promulgated under the Securities Act;
(iii) respond as promptly as reasonably  possible to any comments  received from
the  Commission  with respect to the  Registration  Statement  or any  amendment
thereto and as  promptly as  reasonably  possible  provide


                                      -5-
<PAGE>

the  Holders  true and  complete  copies of all  correspondence  from and to the
Commission  relating  to the  Registration  Statement;  and (iv)  comply  in all
material respects with the provisions of the Securities Act and the Exchange Act
with respect to the  disposition of all  Registrable  Securities  covered by the
Registration  Statement  during the  applicable  period in  accordance  with the
intended  methods  of  disposition  by the  Holders  thereof  set  forth  in the
Registration Statement as so amended or in such Prospectus as so supplemented.

     (c) Notify the Holders of Registrable  Securities to be sold, their Special
Counsel and any managing  underwriters as promptly as reasonably  possible (and,
in the case of (i)(A)  below,  not less than five (5) days prior to such filing)
and (if  requested by any such  Person)  confirm such notice in writing no later
than one (1) Business  Day  following  the day (i)(A) when a  Prospectus  or any
Prospectus supplement or post-effective  amendment to the Registration Statement
is proposed to be filed;  (B) when the Commission  notifies the Company  whether
there  will be a  "review"  of such  Registration  Statement  and  whenever  the
Commission comments in writing on such Registration Statement (the Company shall
provide true and complete  copies thereof and all written  responses  thereto to
each of the Holders);  and (C) with respect to the Registration Statement or any
post-effective  amendment,  when  the  same has  become  effective;  (ii) of any
request by the Commission or any other Federal or state  governmental  authority
for amendments or supplements to the Registration Statement or Prospectus or for
additional  information;  (iii) of the  issuance by the  Commission  of any stop
order suspending the effectiveness of the Registration Statement covering any or
all of the Registrable  Securities or the initiation of any Proceedings for that
purpose;  (iv) if at any time any of the  representations  and warranties of the
Company  contained  in any  agreement  (including  any  underwriting  agreement)
contemplated hereby ceases to be true and correct in all material respects;  (v)
of the receipt by the Company of any notification with respect to the suspension
of the  qualification or exemption from  qualification of any of the Registrable
Securities for sale in any jurisdiction, or the initiation or threatening of any
Proceeding for such purpose;  and (vi) of the occurrence of any event that makes
any statement made in the  Registration  Statement or Prospectus or any document
incorporated  or deemed to be  incorporated  therein by reference  untrue in any
material respect or that requires any revisions to the  Registration  Statement,
Prospectus or other documents so that, in the case of the Registration Statement
or the Prospectus,  as the case may be, it will not contain any untrue statement
of a material  fact or omit to state any  material  fact  required  to be stated
therein  or  necessary  to  make  the  statements   therein,  in  light  of  the
circumstances under which they were made, not misleading.

     (d) Use its best efforts to avoid the  issuance  of, or, if issued,  obtain
the withdrawal of (i) any order suspending the effectiveness of the Registration
Statement,  or (ii) any  suspension  of the  qualification  (or  exemption  from
qualification)   of  any  of  the   Registrable   Securities  for  sale  in  any
jurisdiction, at the earliest practicable moment.

     (e) If requested by any managing  underwriter  or the Holders of a majority
in interest  of the  Registrable  Securities  to be sold in  connection  with an
Underwritten  Offering,  (i) promptly incorporate in a Prospectus  supplement or
post-effective  amendment to the Registration Statement such information as such
managing  underwriters  and such  Holders  reasonably  agree  should be included
therein,  and (ii) make all required  filings of such  Prospectus  supplement or
such  post-effective  amendment  as soon as  practicable  after the  Company has
received  notification 


                                      -6-
<PAGE>

of  the  matters  to  be   incorporated   in  such   Prospectus   supplement  or
post-effective  amendment;  provided,  however,  that the  Company  shall not be
required to take any action  pursuant to this  Section  3(e) that would,  in the
opinion of counsel for the Company,  violate applicable law, rule or regulation,
or be materially detrimental to the business prospects of the Company.

     (f)  Furnish  to each  Holder,  their  Special  Counsel  and  any  managing
underwriters,  without charge,  at least one conformed copy of each Registration
Statement  and  each  amendment  thereto,  including  financial  statements  and
schedules,  all documents  incorporated or deemed to be incorporated  therein by
reference,  and all exhibits to the extent  requested by such Person  (including
those  previously  furnished or  incorporated  by reference)  promptly after the
filing of such documents with the Commission.

     (g)  Promptly  deliver  to each  Holder,  their  Special  Counsel,  and any
underwriters,  without charge,  as many copies of the Prospectus or Prospectuses
(including each form of prospectus) and each amendment or supplement  thereto as
such Persons may reasonably request;  and the Company hereby consents to the use
of such  Prospectus  and each  amendment  or  supplement  thereto by each of the
selling Holders and any underwriters in connection with the offering and sale of
the  Registrable  Securities  covered by such  Prospectus  and any  amendment or
supplement thereto.

     (h) Prior to any public  offering of Registrable  Securities,  use its best
efforts to  register  or qualify or  cooperate  with the  selling  Holders,  any
underwriters  and their Special Counsel in connection  with the  registration or
qualification  (or exemption from such  registration or  qualification)  of such
Registrable  Securities for offer and sale under the securities or Blue Sky laws
of such  jurisdictions  within  the United  States as any Holder or  underwriter
requests  in  writing,  to keep  each such  registration  or  qualification  (or
exemption therefrom) effective during the Effectiveness Period and to do any and
all other acts or things  necessary or advisable  to enable the  disposition  in
such  jurisdictions  of the  Registrable  Securities  covered by a  Registration
Statement;  provided, however, that the Company shall not be required to qualify
generally to do business in any  jurisdiction  where it is not then so qualified
or to take any action that would subject it to general service of process in any
such jurisdiction  where it is not then so subject or subject the Company to any
material tax in any such jurisdiction where it is not then so subject.

     (i) Cooperate with the Holders and any managing  underwriters to facilitate
the timely  preparation  and delivery of certificates  representing  Registrable
Securities to be delivered to a transferee pursuant to a Registration Statement,
which  certificates shall be free, to the extent permitted by applicable law, of
all restrictive legends, and to enable such Registrable Securities to be in such
denominations and registered in such names as any such managing  underwriters or
Holders may request at least two Business Days prior to any sale of  Registrable
Securities.

     (j) Upon the occurrence of any event  contemplated by Section 3(c)(vi),  as
promptly as reasonably possible, prepare a supplement or amendment,  including a
post-effective  amendment,  to the Registration Statement or a supplement to the
related  Prospectus or any document  incorporated  or deemed to be  incorporated
therein  by  reference,  and file  any  other  required  document  so  that,  as
thereafter  delivered,  neither the  Registration  Statement nor such


                                      -7-
<PAGE>

Prospectus will contain an untrue  statement of a material fact or omit to state
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein,  in light of the circumstances  under which they were made,
not misleading.

     (k) Use its best efforts to cause all  Registrable  Securities  relating to
such  Registration  Statement  to be listed on the Nasdaq  SmallCap  Market (the
"NASDAQ")  and any  other  securities  exchange,  quotation  system,  market  or
over-the-counter  bulletin board, if any, on which similar  securities issued by
the  Company  are then  listed as and when  required  pursuant  to the  Purchase
Agreement.

     (l) Enter into such  agreements  (including  an  underwriting  agreement in
form,  scope and substance as is customary in  Underwritten  Offerings) and take
all such other  actions in  connection  therewith  (including  those  reasonably
requested  by any  managing  underwriters  and the  Holders of a majority of the
Registrable  Securities  being  sold) in order to  expedite  or  facilitate  the
disposition of such Registrable  Securities,  and whether or not an underwriting
agreement is entered into, (i) make such  representations and warranties to such
Holders and such underwriters as are customarily made by issuers to underwriters
in underwritten  public  offerings,  and confirm the same if and when requested;
(ii) in the case of an  Underwritten  Offering obtain and deliver copies thereof
to each Holder and the managing underwriters,  if any, of opinions of counsel to
the  Company  and  updates  thereof  addressed  to each  Holder  and  each  such
underwriter,  in form, scope and substance  reasonably  satisfactory to any such
managing  underwriters  and Special Counsel to the selling Holders  covering the
matters customarily covered in opinions requested in Underwritten  Offerings and
such other  matters as may be reasonably  requested by such Special  Counsel and
underwriters;  (iii)  immediately prior to the effectiveness of the Registration
Statement, and, in the case of an Underwritten Offering, at the time of delivery
of any  Registrable  Securities sold pursuant  thereto,  use its best reasonable
efforts  to  obtain  and  deliver   copies  to  the  Holders  and  the  managing
underwriters,  if any, of "cold  comfort"  letters and updates  thereof from the
independent  auditors of the Company (and, if necessary,  any other  independent
certified public accountants of any subsidiary of the Company or of any business
acquired by the Company for which financial statements and financial data is, or
is required to be,  included in the  Registration  Statement),  addressed to the
Company in form and substance as are customary in connection  with  Underwritten
Offerings;  (iv) if an  underwriting  agreement is entered into,  the same shall
contain  indemnification  provisions  and  procedures  no less  favorable to the
selling Holders and the underwriters,  if any, than those set forth in Section 5
(or  such  other   provisions   and   procedures   acceptable  to  the  managing
underwriters,  if any,  and  holders of a  majority  of  Registrable  Securities
participating in such Underwritten Offering); and (v) deliver such documents and
certificates as may be reasonably  requested by the Holders of a majority of the
Registrable  Securities  being sold,  their  Special  Counsel  and any  managing
underwriters  to evidence  the  continued  validity of the  representations  and
warranties made pursuant to clause 3(l)(i) above and to evidence compliance with
any  customary  conditions  contained  in the  underwriting  agreement  or other
agreement entered into by the Company.

     (m)  Make   available   for   inspection  by  the  selling   Holders,   any
representative of such Holders, any underwriter participating in any disposition
of  Registrable  Securities,  and any  attorney or  accountant  retained by such
selling  Holders or  underwriters,  at the offices where


                                      -8-
<PAGE>

normally  kept,  during  reasonable  business  hours,  all  financial  and other
records,  pertinent  corporate  documents and  properties of the Company and its
subsidiaries,  and cause the  officers,  directors,  agents and employees of the
Company and its  subsidiaries  to supply all information in each case reasonably
requested  by  any  such  Holder,  representative,   underwriter,   attorney  or
accountant in connection with the  Registration  Statement;  provided,  however,
that any information  that is determined in good faith by the Company in writing
to be of a confidential nature at the time of delivery of such information shall
be kept confidential by such Persons,  unless (i) disclosure of such information
is  required  by court or  administrative  order or is  necessary  to respond to
inquiries of regulatory authorities; (ii) disclosure of such information, in the
opinion of counsel to such Person,  is required by law;  (iii) such  information
becomes generally available to the public other than as a result of a disclosure
or  failure  to  safeguard  by such  Person;  or (iv) such  information  becomes
available to such Person from a source other than the Company and such source is
not known by such  Person to be bound by a  confidentiality  agreement  with the
Company.

     (n) Comply with all applicable rules and regulations of the Commission.

     (o) The Company may require each  selling  Holder to furnish to the Company
such information  regarding the distribution of such Registrable  Securities and
the  beneficial  ownership of Common Stock held by such Holder as is required by
law to be disclosed in the Registration  Statement,  and the Company may exclude
from  such  registration  the  Registrable  Securities  of any such  Holder  who
unreasonably  fails to furnish such  information  within a reasonable time after
receiving such request.

     If the Registration  Statement refers to any Holder by name or otherwise as
the holder of any  securities  of the  Company,  then such Holder shall have the
right to require (if such  reference  to such Holder by name or otherwise is not
required by the Securities Act or any similar Federal statute then in force) the
deletion of the  reference to such Holder in any  amendment or supplement to the
Registration  Statement  filed or  prepared  subsequent  to the time  that  such
reference ceases to be required.

     Each Holder  covenants and agrees that (i) it will not sell any Registrable
Securities under the Registration  Statement until it has received copies of the
Prospectus as then amended or  supplemented  as contemplated in Section 3(g) and
notice from the Company that such Registration  Statement and any post-effective
amendments  thereto have become  effective as  contemplated  by Section 3(c) and
(ii) it and its officers,  directors or Affiliates, if any, will comply with the
prospectus  delivery  requirements  of the Securities Act as applicable to it in
connection  with sales of Registrable  Securities  pursuant to the  Registration
Statement.

     Each Holder agrees by its acquisition of such Registrable  Securities that,
upon receipt of a notice from the Company of the  occurrence of any event of the
kind described in Section 3(c)(ii),  3(c)(iii),  3(c)(iv),  3(c)(v) or 3(c)(vi),
such  Holder  will  forthwith   discontinue   disposition  of  such  Registrable
Securities under the  Registration  Statement until such Holder's receipt of the
copies of the  supplemented  Prospectus  and/or amended  Registration  Statement
contemplated  by Section 3(j), or until it is advised in writing (the  "Advice")
by the Company that 


                                      -9-
<PAGE>

the use of the applicable  Prospectus  may be resumed,  and, in either case, has
received copies of any additional or supplemental  filings that are incorporated
or deemed to be  incorporated  by reference in such  Prospectus or  Registration
Statement.

     4. Registration Expenses

     (a) All fees and expenses incident to the performance of or compliance with
this Agreement by the Company,  except as and to the extent specified in Section
4(b),  shall be borne by the Company  whether or not pursuant to an Underwritten
Offering  and  whether  or not the  Registration  Statement  is filed or becomes
effective and whether or not any Registrable Securities are sold pursuant to the
Registration  Statement.  The fees and  expenses  referred  to in the  foregoing
sentence shall include, without limitation, (i) all registration and filing fees
(including,  without  limitation,  fees and expenses (A) with respect to filings
required to be made with the NASDAQ or each other securities  exchange or market
on which Registrable  Securities are required  hereunder to be listed and (B) in
compliance  with  state  securities  or  Blue  Sky  laws   (including,   without
limitation, fees and disbursements of counsel for the holders in connection with
Blue  Sky  qualifications  or  exemptions  of  the  Registrable  Securities  and
determination  of the eligibility of the  Registrable  Securities for investment
under the laws of such jurisdiction as the managing underwriters, if any, or the
Holders of a majority of Registrable  Securities may designate)),  (ii) printing
expenses (including,  without limitation,  expenses of printing certificates for
Registrable   Securities  and  of  printing  prospectuses  if  the  printing  of
prospectuses  is  requested  by the  managing  underwriters,  if any,  or by the
holders of a majority of the Registrable Securities included in the Registration
Statement),  (iii)  messenger,  telephone and delivery  expenses,  (iv) fees and
disbursements of counsel for the Company and Special Counsel for the Holders (in
the case of Special Counsel for the Holders,  such fees and disbursements  shall
not exceed $7,500),  (v) Securities Act liability  insurance,  if the Company so
desires such insurance, and (vi) fees and expenses of all other Persons retained
by  the  Company  in  connection  with  the  consummation  of  the  transactions
contemplated  by this Agreement.  In addition,  the Company shall be responsible
for all of its internal expenses incurred in connection with the consummation of
the transactions contemplated by this Agreement (including,  without limitation,
all salaries and expenses of its  officers  and  employees  performing  legal or
accounting  duties),  the  expense of any annual  audit,  the fees and  expenses
incurred in  connection  with the listing of the  Registrable  Securities on any
securities exchange as required hereunder.

     (b) If the Holders require an Underwritten  Offering  pursuant to the terms
hereof,  the Company shall be  responsible  for all costs,  fees and expenses in
connection therewith,  except for the fees and disbursements of the Underwriters
(including any  underwriting  commissions and discounts) and their legal counsel
and accountants.  By way of illustration  which is not intended to diminish from
the provisions of Section 4(a),  the Holders shall not be  responsible  for, and
the Company shall be required to pay the fees or  disbursements  incurred by the
Company (including by its legal counsel and accountants) in connection with, the
preparation  and filing of a Registration  Statement and related  Prospectus for
such offering, the maintenance of such Registration Statement in accordance with
the terms hereof,  the listing of the Registrable  Securities in accordance with
the  requirements  hereof,  and  printing  expenses  incurred to comply with the
requirements hereof.

     5. Indemnification

     (a) Indemnification by the Company. The Company shall,  notwithstanding any
termination  of this  Agreement,  indemnify and hold  harmless each Holder,  the
officers,  directors, agents (including any underwriters retained by such Holder
in  connection  with the  offer  and sale of  Registrable  Securities),  brokers
(including  brokers who offer and sell Registrable  Securities as principal as a
result of a pledge  or any  failure  to  perform  under a margin  call of Common
Stock),  investment  advisors  and  employees  of each of them,  each Person who
controls any such Holder (within the meaning of Section 15 of the Securities Act
or Section  20 of the  Exchange  Act) and the  officers,  directors,  agents and
employees of each such  controlling  Person,  to the fullest extent permitted by
applicable  law,  from  and  against  any  and  all  losses,  claims,   damages,
liabilities,  costs  (including,  without  limitation,  costs of preparation and
attorneys' fees) and expenses (collectively, "Losses"), as incurred, arising out
of or  relating to any untrue or alleged  untrue  statement  of a material  fact
contained  in  the  Registration  Statement,  any  Prospectus  or  any  form  of
prospectus  or in any  amendment  or  supplement  thereto or in any  preliminary
prospectus, or arising out of or relating to any omission or alleged omission of
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein  (in the case of any  Prospectus  or form of  prospectus  or
supplement  thereto,  in light of the circumstances  under which they were made)
not  misleading,  except to the extent,  but only to the  extent,  (i) that such
untrue statements or omissions are based solely upon information  regarding such
Holder  furnished  in writing to the  Company by such Holder  expressly  for use
therein,  which  information  was  reasonably  relied on by the  Company for use
therein or to the extent  that such  information  relates to such Holder or such
Holder's  proposed  method of  distribution  of  Registrable  Securities and was
reviewed and expressly  approved in writing by such Holder  expressly for use in
the Registration Statement, such Prospectus or such form of Prospectus or in any
amendment or  supplement  thereto,  or (ii) in the case of the  occurrence of an
event of the type specified in Section 3(c)(ii) - (vi), the use by the Holder or
such Indemnified Party of an outdated or defective  Prospectus after the Company
has notified such Person in writing that the Prospectus is outdated or defective
and prior to the  receipt by such Person of the Advice  contemplated  in Section
3(o). The Company shall notify the Holders promptly of the  institution,  threat
or assertion of any Proceeding of which the Company is aware in connection  with
the transactions contemplated by this Agreement.

     (b)  Indemnification  by Holders.  Each  Holder  shall,  severally  and not
jointly,  indemnify  and hold  harmless the Company,  its  directors,  officers,
agents and employees,  each Person who controls the Company  (within the meaning
of Section 15 of the Securities Act and Section 20 of the Exchange Act), and the
directors,  officers,  agents or employees of such controlling  Persons,  to the
fullest  extent  permitted by  applicable  law,  from and against all Losses (as
determined by a court of competent jurisdiction in a final judgement not subject
to appeal or  review)  arising  solely  out of or based  solely  upon any untrue
statement  of a material  fact  contained  in the  Registration  Statement,  any
Prospectus,  or any  form  of  prospectus,  or in any  amendment  or  supplement
thereto,  or  arising  solely  out of or based  solely  upon any  omission  of a
material fact required to be stated  therein or necessary to make the statements
therein not misleading to the extent,  but only to the extent,  that such untrue
statement or omission is contained in any information so furnished in writing by
such  Holder to the  Company  specifically  for  inclusion  in the  Registration
Statement or such  Prospectus and that such  information  was reasonably  relied

                                      -11-
<PAGE>

upon by the Company for use in the  Registration  Statement,  such Prospectus or
such form of prospectus or to the extent that such  information  relates to such
Holder  or  such  Holder's   proposed  method  of  distribution  of  Registrable
Securities  and was  reviewed and  expressly  approved in writing by such Holder
expressly for use in the Registration Statement, such Prospectus or such form of
Prospectus,  or in any  amendment or supplement  thereto.  In no event shall the
liability of any selling  Holder  hereunder be greater in amount than the dollar
amount  of the  net  proceeds  received  by such  Holder  upon  the  sale of the
Registrable Securities giving rise to such indemnification obligation.

     (c) Conduct of  Indemnification  Proceedings.  If any  Proceeding  shall be
brought or asserted  against  any Person  entitled to  indemnity  hereunder  (an
"Indemnified  Party"),  such Indemnified  Party shall promptly notify the Person
from whom  indemnity is sought (the  "Indemnifying  Party") in writing,  and the
Indemnifying Party shall assume the defense thereof, including the employment of
counsel reasonably  satisfactory to the Indemnified Party and the payment of all
fees and expenses  incurred in connection with defense thereof;  provided,  that
the failure of any  Indemnified  Party to give such notice shall not relieve the
Indemnifying Party of its obligations or liabilities pursuant to this Agreement,
except (and only) to the extent that it shall be finally  determined  by a court
of  competent  jurisdiction  (which  determination  is not  subject to appeal or
further  review)  that  such  failure  shall  have  proximately  and  materially
adversely prejudiced the Indemnifying Party.

     An Indemnified Party shall have the right to employ separate counsel in any
such  Proceeding  and to participate  in the defense  thereof,  but the fees and
expenses of such counsel  shall be at the expense of such  Indemnified  Party or
Parties  unless:  (1) the  Indemnifying  Party has agreed in writing to pay such
fees and expenses;  or (2) the Indemnifying  Party shall have failed promptly to
assume  the  defense  of  such  Proceeding  and  to  employ  counsel  reasonably
satisfactory to such Indemnified Party in any such Proceeding;  or (3) the named
parties to any such Proceeding  (including any impleaded  parties)  include both
such Indemnified  Party and the Indemnifying  Party, and such Indemnified  Party
shall have been  advised by counsel  that a conflict  of  interest  is likely to
exist if the same  counsel  were to  represent  such  Indemnified  Party and the
Indemnifying  Party (in which  case,  if such  Indemnified  Party  notifies  the
Indemnifying  Party in writing that it elects to employ separate  counsel at the
expense of the Indemnifying  Party,  the  Indemnifying  Party shall not have the
right to assume the defense  thereof and such counsel shall be at the expense of
the  Indemnifying  Party).  The  Indemnifying  Party shall not be liable for any
settlement of any such Proceeding  effected without its written  consent,  which
consent shall not be unreasonably withheld. No Indemnifying Party shall, without
the prior written consent of the Indemnified Party, effect any settlement of any
pending Proceeding in respect of which any Indemnified Party is a party,  unless
such settlement includes an unconditional release of such Indemnified Party from
all liability on claims that are the subject matter of such Proceeding.

     All fees and expenses of the Indemnified  Party (including  reasonable fees
and  expenses  to the  extent  incurred  in  connection  with  investigating  or
preparing  to defend  such  Proceeding  in a manner not  inconsistent  with this
Section) shall be paid to the Indemnified Party, as incurred, within 10 Business
Days of written notice thereof to the Indemnifying  Party (regardless of whether
it is  ultimately  determined  that an  Indemnified  Party  is not  entitled  to
indemnifica-


                                      -12-
<PAGE>

tion  hereunder;   provided,  that  the  Indemnifying  Party  may  require  such
Indemnified  Party to undertake  to reimburse  all such fees and expenses to the
extent it is finally  judicially  determined that such Indemnified  Party is not
entitled to indemnification hereunder).

     (d) Contribution. If a claim for indemnification under Section 5(a) or 5(b)
is  unavailable  to  an  Indemnified  Party  (by  reason  of  public  policy  or
otherwise),   then  each  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,  in  such  proportion  as is
appropriate  to  reflect  the  relative  fault  of the  Indemnifying  Party  and
Indemnified  Party in connection with the actions,  statements or omissions that
resulted in such Losses as well as any other relevant equitable  considerations.
The relative fault of such  Indemnifying  Party and  Indemnified  Party shall be
determined by reference to, among other things,  whether any action in question,
including any untrue or alleged untrue  statement of a material fact or omission
or alleged omission of a material fact, has been taken or made by, or relates to
information  supplied by, such Indemnifying  Party or Indemnified Party, and the
parties'  relative intent,  knowledge,  access to information and opportunity to
correct or prevent  such  action,  statement  or  omission.  The amount  paid or
payable by a party as a result of any Losses shall be deemed to include, subject
to the limitations set forth in Section 5(c), any reasonable attorneys' or other
reasonable  fees or  expenses  incurred  by such  party in  connection  with any
Proceeding to the extent such party would have been indemnified for such fees or
expenses if the  indemnification  provided for in this Section was  available to
such party in accordance with its terms.

     The  parties  hereto  agree  that it  would  not be just and  equitable  if
contribution  pursuant  to  this  Section  5(d)  were  determined  by  pro  rata
allocation or by any other method of allocation  that does not take into account
the equitable considerations referred to in the immediately preceding paragraph.
Notwithstanding the provisions of this Section 5(d), no Holder shall be required
to contribute, in the aggregate, any amount in excess of the amount by which the
proceeds  actually  received  by such  Holder  from the sale of the  Registrable
Securities subject to the Proceeding exceeds the amount of any damages that such
Holder has  otherwise  been  required to pay by reason of such untrue or alleged
untrue statement or omission or alleged omission. No Person guilty of fraudulent
misrepresentation  (within the meaning of Section 11(f) of the  Securities  Act)
shall be  entitled  to  contribution  from any Person who was not guilty of such
fraudulent misrepresentation.

     The indemnity and contribution  agreements contained in this Section are in
addition  to any  liability  that  the  Indemnifying  Parties  may  have  to the
Indemnified Parties.

     6. Miscellaneous

     (a)  Remedies.  In the event of a breach by the Company or by a Holder,  of
any of their  obligations under this Agreement,  each Holder or the Company,  as
the case may be, in addition to being entitled to exercise all rights granted by
law and under this Agreement, including recovery of damages, will be entitled to
specific  performance of its rights under this  Agreement.  The Company and each
Holder agree that monetary damages would not provide  adequate  compensation for
any losses incurred by reason of a breach by it of any of the provisions of this

                                      -13-
<PAGE>

Agreement  and  hereby  further  agrees  that,  in the event of any  action  for
specific  performance in respect of such breach, it shall waive the defense that
a remedy at law would be adequate.

     (b)  No  Inconsistent  Agreements.  Neither  the  Company  nor  any  of its
subsidiaries  has,  as of the date  hereof,  nor shall the Company or any of its
subsidiaries,  on or after the date of this Agreement,  enter into any agreement
with respect to its securities that is  inconsistent  with the rights granted to
the Holders in this Agreement or otherwise conflicts with the provisions hereof.
Except as and to the extent  specified  in  Schedule  6(b)  hereto,  neither the
Company nor any of its  subsidiaries  has previously  entered into any agreement
granting  any  registration  rights  with  respect  to the  Common  Stock or any
securities  that are convertible  into or  exchangeable  for Common Stock to any
Person  except for  registration  rights which are no longer in effect.  Without
limiting the  generality of the  foregoing,  without the written  consent of the
Holders  of a  majority  of the then  outstanding  Registrable  Securities,  the
Company  shall not grant to any  Person  the right to  request  the  Company  to
register  any  securities  of the Company  under the  Securities  Act unless the
rights so granted are subject in all respects to the prior rights in full of the
Holders set forth herein, and are not otherwise in conflict or inconsistent with
the provisions of this Agreement.

     (c) No Piggyback on Registrations. Except as and to the extent specified in
Schedule 6(b) hereto, neither the Company nor any of its security holders (other
than the Holders in such capacity pursuant hereto) may include securities of the
Company in the Registration Statement other than the Registrable Securities, and
the Company shall not after the date hereof enter into any  agreement  providing
any such right to any of its security holders.

     (d) Piggy-Back Registrations. If at any time when there is not an effective
Registration  Statement  covering  all of the  Registrable  Securities  and  the
Underlying  Shares,  the Company  shall  determine  to prepare and file with the
Commission a registration  statement relating to an offering for its own account
or the  account  of  others  under  the  Securities  Act  of  any of its  equity
securities,  other than on Form S-4 or Form S-8 (each as  promulgated  under the
Securities Act) or their then  equivalents  relating to equity  securities to be
issued solely in connection  with any  acquisition  of any entity or business or
equity  securities  issuable in connection  with stock option or other  employee
benefit  plans,  then the  Company  shall  send to each  holder  of  Registrable
Securities  written notice of such determination and, if within twenty (20) days
after receipt of such notice,  any such holder shall so request in writing,  the
Company  shall  include in such  registration  statement all or any part of such
Registrable Securities such holder requests to be registered; provided, however,
that the Company  shall not be required to register any  Registrable  Securities
pursuant to this Section 7(d) that are eligible for sale pursuant to Rule 144(k)
of the Commission.

     (e) Amendments and Waivers. The provisions of this Agreement, including the
provisions of this sentence, may not be amended,  modified or supplemented,  and
waivers or consents to departures  from the provisions  hereof may not be given,
unless the same shall be in writing and signed by the Company and the Holders of
at least two-thirds of the then outstanding  Registrable  Securities;  provided,
however,  that, for the purposes of this sentence,  Registrable  Securities that
are owned,  directly or  indirectly,  by the  Company,  or an  Affiliate  of the
Company are not deemed outstanding.  Notwithstanding the foregoing,  a waiver or
consent to depart  from


                                      -14-
<PAGE>

the provisions  hereof with respect to a matter that relates  exclusively to the
rights of Holders and that does not directly or indirectly  affect the rights of
other Holders may be given by Holders of at least a majority of the  Registrable
Securities to which such waiver or consent relates; provided,  however, that the
provisions of this sentence may not be amended, modified, or supplemented except
in accordance with the provisions of the immediately preceding sentence.

     (f)  Notices.  Any and all notices or other  communications  or  deliveries
required or permitted to be provided  hereunder shall be in writing and shall be
deemed given and effective on the earliest of (i) the date of  transmission,  if
such  notice or  communication  is  delivered  via  facsimile  at the  facsimile
telephone  number  specified in this Section  prior to 8:00 p.m.  (New York City

if such notice or  communication  is delivered  via  facsimile at the  facsimile
telephone number  specified in the Purchase  Agreement later than 8:00 p.m. (New
York City time) on any date and earlier than 11:59 p.m.  (New York City time) on
such date,  (iii) the Business  Day  following  the date of mailing,  if sent by
overnight delivery by nationally  recognized  overnight courier service, or (iv)
