          accordance with Section 6.1.

          shall any  Junior  Securities  be  redeemed,  purchased  or  otherwise
          acquired  (other than a redemption,  purchase or other  acquisition of
          shares of Common Stock made for  purposes of an employee  incentive or
          benefit plan (including a stock option plan) of the Corporation or any

          indirectly,  nor shall any moneys be paid to or made  available  for a
          sinking  fund  for  the   redemption  of  any  shares  of  any  Junior

          securities of the  Corporation  or any of its  Subsidiaries  by way of
          dividend or spin-off) on shares of its Common Stock, then, and in each
          such case, in addition to the dividend  obligation of the  Corporation
          specified in  Section 4(a)  hereof,  the  Corporation  shall  declare,
          order,  pay and make the same dividend or  distribution to each Holder
          of Series C  Preferred  Stock as would have been made with  respect to
          the  number of Common  Shares the Holder  would have  received  had it
          converted  all of its Series C Preferred  Shares,  and  exercised  the
          Warrant held by it in full for all the Common  Shares then  underlying
          the Warrant, immediately prior to such dividend or distribution.

     For purposes of this  Section 6.1, a "Valuation  Event" shall mean an event
in which the Corporation takes any of the following actions:

     (a) subdivides or combines its Capital Shares;

     (b) makes any distribution on its Capital Shares;

     (c) issues any additional Capital Shares (the "Additional Capital Shares"),
otherwise than as provided in the foregoing Sections 6.1(a) and 6.1(b) above, at
a price per share  less,  or for other  consideration  lower,  than the  Current
Market  Price  in  effect  immediately  prior  to  such  issuances,  or  without
consideration, except for issuances under employee benefit plans consistent with
those presently in effect and issuances under  presently  outstanding  warrants,
options or convertible securities;

     (d)  issues  any  warrants,  options or other  rights to  subscribe  for or
purchase  any  Additional  Capital  Shares  if the  price  per  share  for which
Additional  Capital  Shares may at any time  thereafter be issuable  pursuant to
such  warrants,  options or other rights  shall be less than the Current  Market
Price in effect immediately prior to such issuance;

     (e) issues any securities  convertible  into or exchangeable or exercisable
for  Additional  Capital  Shares  if  the  consideration  per  share  for  which
Additional Capital Shares may at any time thereafter be issuable pursuant to the
terms of such convertible,  exchangeable or exercisable securities shall be less
than the Current Market Price in effect immediately prior to such issuance;

     (f) announces or effects a Fundamental Corporate Change;

     (g) makes any  distribution  of its assets or evidences of  indebtedness to
the holders of its  Capital  Shares as a dividend  in  liquidation  or by way of
return of capital or other than as a dividend payable out of earnings or surplus
legally  available  for the payment of  dividends  under  applicable  law or any
distribution to such holders made in respect of the sale of all or substantially
all of the Corporation's assets (other than under the circumstances provided for
in the foregoing Sections 6.1(a) through 6.1(e)); or

     (h) takes any action  affecting the number of Outstanding  Capital  Shares,
other than an action  described in any of the foregoing  Sections 6.1(a) through
6.1(g) hereof, inclusive, which in the opinion of the Holder, determined in good
faith, would have a material adverse effect upon the rights of the Holder at the
time of a conversion of the Preferred Stock or is reasonably likely to result in
a decrease in the Market Price.

     Section 6.2 Exercise of Conversion Privilege

     (a) Conversion of the Series C Preferred  Stock may be exercised,  in whole
or in part, by the Holder by  telecopying  an executed and completed  Conversion
Notice to the Corporation.  Each date on which a Conversion Notice is telecopied
to the  Corporation in accordance  with the provisions of this Section 6.2 shall
constitute a Conversion Date. The Corporation  shall convert the Preferred Stock
and issue the Common Stock Issued at Conversion, and all voting and other rights
associated  with  the  beneficial  ownership  of  the  Common  Stock  Issued  at
Conversion  shall vest with the Holder,  effective as of the Conversion  Date at
the time specified in the Conversion  Notice.  The Conversion  Notice also shall
state the name or names  (with  addresses)  of the Persons who are to become the
holders  of the  Common  Stock  Issued at  Conversion  in  connection  with such
conversion.  The Holder shall deliver the shares of Series C Preferred  Stock to
the Corporation by express courier within 30 days following the Conversion Date.
Upon  surrender for  conversion,  the Preferred  Stock shall be accompanied by a
proper  assignment  thereof  to the  Corporation  or be  endorsed  in blank.  As
promptly as practicable after the receipt of the Conversion Notice as aforesaid,
but in any  event  not more  than five  Business  Days  after the  Corporation's
receipt of such Conversion  Notice,  the Corporation  shall (i) issue the Common
Stock issued at Conversion in accordance  with the provisions of this Article 6,
and (ii) cause to be mailed for delivery by overnight  courier to the Holder (x)
a  certificate  or  certificate(s)  representing  the number of Common Shares to
which the Holder is entitled by virtue of such conversion, (y) cash, as provided
in Section 6.3, in respect of any fraction of a Common Share  issuable upon such
conversion  and  (z) if  the  Corporation  chooses  to pay  accrued  and  unpaid
dividends in cash, cash in the amount of accrued and unpaid  dividends as of the
Conversion  Date. Such  conversion  shall be deemed to have been effected at the
time at which the Conversion  Notice indicates so long as the Series C Preferred
Stock shall have been  surrendered  as aforesaid at such time,  and at such time
the rights of the Holder of the Series C Preferred  Stock, as such,  shall cease
and the Person or Persons  in whose  name or names the  Common  Stock  Issued at
Conversion  shall be  issuable  shall be deemed  to have  become  the  holder or
holders of record of the Common  Shares  represented  thereby and all voting and
other rights  associated  with the  beneficial  ownership of such Common  Shares
shall at such time vest with such Person or Persons. The Conversion Notice shall
constitute a contract between the Holder and the Corporation, whereby the Holder
shall be deemed to  subscribe  for the number of Common  Shares which it will be
entitled to receive upon such  conversion  and, in payment and  satisfaction  of
such  subscription (and for any cash adjustment to which it is entitled pursuant
to Section 6.3),  to surrender  the Series C Preferred  Stock and to release the
Corporation from all liability  thereon.  No cash payment  aggregating less than
$1.00 shall be required to be given unless specifically requested by the Holder.

     (b) If, at any time (i) the Corporation challenges,  disputes or denies the
right of the Holder  hereof to effect the  conversion  of the Series C Preferred
Stock into Common Shares or otherwise dishonors or rejects any Conversion Notice
delivered in accordance  with this Section 6.2 or (ii) any third party commences
any lawsuit or  proceeding  or  otherwise  asserts any claim before any court or
public or governmental authority which seeks to challenge,  deny, enjoin, limit,
modify, delay or dispute the right of the Holder hereof to effect the conversion
of the Series C Preferred  Stock into Common Shares,  then the Holder shall have
the right,  by written  notice to the  Corporation,  to require the  Corporation
promptly to redeem the Series C Preferred  Stock for cash at a redemption  price
equal to 135% of the Stated Value  thereof  together with all accrued and unpaid
dividends  (whether or not earned or  declared,  whether or not there were funds
legally  available  for the payment of  dividends  and whether or not a Dividend
Payment Due Date has  occurred  since the last  dividend  payment)  thereon (the
"Mandatory  Purchase  Amount").  Under any of the circumstances set forth above,
the  Corporation  shall be responsible for the payment of all costs and expenses
of the  Holder,  including  reasonable  legal  fees  and  expenses,  as and when
incurred  in  disputing  any such action or pursuing  its rights  hereunder  (in
addition to any other rights of the Holder).

     (c) The Holder  shall be  entitled  to exercise  its  conversion  privilege
notwithstanding  the commencement of any case under 11 U.S.C.  (subscript)101 et
seq. (the "Bankruptcy Code"). In the event the Corporation is a debtor under the
Bankruptcy  Code, the Corporation  hereby waives to the fullest extent permitted
any  rights to relief it may have under 11 U.S.C.  (subscript)362  in respect of
the Holder's conversion privilege.  The Corporation hereby waives to the fullest
extent permitted any rights to relief it may have under 11 U.S.C. (subscript)362
in respect of the conversion of the Series C Preferred  Stock.  The  Corporation
agrees, without cost or expense to the Holder, to take or consent to any and all
action necessary to effectuate relief under 11 U.S.C. (subscript)362.

     Section 6.3 Fractional Shares

     No fractional Common Shares or scrip representing  fractional Common Shares
shall be issued upon conversion of the Series C Preferred Stock.  Instead of any
fractional  Common Shares which  otherwise  would be issuable upon conversion of
the Series C Preferred  Stock,  the  Corporation  shall pay a cash adjustment in
respect of such  fraction in an amount equal to the same  fraction.  Section 6.4
Adjustments to Conversion Price

     For so long as any shares of the Series C Preferred Stock are  outstanding,
if the Corporation  issues and sells pursuant to an exemption from  registration
under the Securities Act (other than pursuant to presently outstanding warrants,
options or convertible securities) (A) Common Shares at a purchase price that is
lower than the  Conversion  Price on the date of issuance of such Common Shares,
(B) warrants or options with an exercise  price on the date of issuance  thereof
that is lower than the Conversion Price for the Holder on such date,  except for
warrants or options issued pursuant to employee stock option agreements or stock
incentive  agreements of the Corporation,  or (C)  convertible,  exchangeable or
exercisable securities with a right to exchange at lower than the Current Market
Price on the date of issuance or conversion, as applicable, of such convertible,
exchangeable or exercisable  securities,  except for stock option  agreements or
stock incentive agreements,  then the Conversion Price shall be reduced to equal
the lowest of any such purchase price, exercise price or exchange price, and the
number of shares of Common  Stock  into which the  Series C  Preferred  Stock is
convertible   pursuant  to  the  second   paragraph  of  Section  6.1  shall  be
correspondingly adjusted. After such reduction, the Conversion Price shall never
exceed the Conversion Price as so reduced,  in spite of any subsequent  increase
in the Market Price.

     Section 6.5 Optional Redemption

     At any time  after the date of  issuance  of the Series C  Preferred  Stock
until the Mandatory  Conversion Date (as defined below),  the Corporation,  upon
notice delivered to the Holder as provided in Section 6.6, may redeem,  in cash,
the Series C Preferred  Stock (but only with  respect to such shares as to which
the Holder has not theretofore  furnished a Conversion Notice in compliance with
Section  6.2),  at 100% of the Stated Value  thereof (the  "Optional  Redemption
Price"),  together with all accrued and unpaid dividends  (whether or not earned
or declared,  whether or not there were funds legally  available for the payment
of dividends and whether or not a Dividend  Payment Due Date has occurred  since
the last dividend  payment)  thereon to the date of redemption (the  "Redemption
Date");  provided,  however,  that the  Corporation may only redeem the Series C
Preferred  Stock under this Section 6.5 if the Current Market Price is less than
the Current Market Price on the Issue Date.  Except as set forth in this Section
6.5, the  Corporation  shall not have the right to redeem the Series C Preferred
Stock.

     Section 6.6 Notice of Redemption

     Notice of  redemption  pursuant  to Section  6.5 shall be  provided  by the
Corporation to the Holder in writing (by registered mail or overnight courier at
the Holder's last address appearing in the Corporation's  security registry) not
less than 10 nor more than 15 days prior to the  Redemption  Date,  which notice
shall  specify  the  Redemption  Date and  refer to  Section  6.5  (including  a
statement of the Current Market Price per Common Share) and this Section 6.6.

     Section 6.7 Surrender of Preferred Stock

     Upon any  redemption of the Series C Preferred  Stock  pursuant to Sections
6.5 and 6.6,  the Holder shall  either  deliver the Series C Preferred  Stock by
hand to the Corporation at its principal executive offices or surrender the same
to the  Corporation at such address by express  courier within 14 days after the
date  that  the  Buyer  receives  payment  therefore.  Payment  of the  Optional
Redemption Price shall be made by the Corporation to the Holder by wire transfer
of immediately available funds to such account(s) as the Holder shall specify to
the  Corporation.  If payment of such Optional  Redemption  Price is not made in
full by the  Redemption  Date,  the Holder shall again have the right to convert
the  Series C  Preferred  Stock as  provided  in Article 6 hereof.

     Section 6.8 Mandatory Conversion

     On the third  anniversary  of the date of this  Certificate  of Designation
(the "Mandatory  Conversion  Date"),  the Corporation shall convert all Series C
Preferred Stock outstanding,  at the Conversion Price utilizing the Stated Value
(plus accrued and unpaid dividends  (whether or not earned or declared,  whether
or not there were funds  legally  available  for the  payment of  dividends  and
whether or not a Dividend  Payment Due Date has occurred since the last dividend
payment)) as the value of each share of Series C Preferred Stock, into shares of
Common  Stock  registered  for  resale  in  open  market   transactions  on  the
Registration Statement (as defined in the Registration Rights Agreement),  which
Registration Statement shall then be effective under the Securities Act. Section

     6.9 Certain Conversion Limitations

     (a) Notwithstanding  anything herein to the contrary,  the Holder shall not
have the right,  and the Corporation  shall not have the obligation,  to convert
all or any portion of the Series C Preferred  Stock (and the  Corporation  shall
not have the right to pay dividends on the Series C Preferred Stock in shares of
Common  Stock) if and to the extent that the issuance to the Holder of shares of
Common Stock upon such conversion (or payment of dividends)  would result in the
Holder  being  deemed  the  "beneficial  owner"  of  more  than  5% of the  then
Outstanding  shares of Common Stock  within the meaning of Section  13(d) of the
Securities  Exchange  Act  of  1934,  as  amended,  and  the  rules  promulgated
thereunder.  If any court of competent  jurisdiction  shall  determine  that the
foregoing  limitation is  ineffective  to prevent a Holder from being deemed the
beneficial owner of more than 5% of the then Outstanding shares of Common Stock,
then  the  Corporation  shall  redeem  so  many  of such  Holder's  shares  (the
"Redemption  Shares") of Series C Preferred Stock as are necessary to cause such
Holder  to be  deemed  the  beneficial  owner  of not  more  than 5% of the then
Outstanding  shares  of Common  Stock.  Upon  such  determination  by a court of
competent  jurisdiction,  the Redemption  Shares shall  immediately  and without
further  action be deemed  returned  to the status of  authorized  but  unissued
shares of Series C Preferred  Stock, and the Holder shall have no interest in or
rights under such Redemption  Shares.  Any and all dividends paid on or prior to
the date of such  determination  shall be deemed dividends paid on the remaining
shares of Series C Preferred Stock held by the Holder.  Such redemption shall be
for cash at a redemption  price equal to the sum of (i) 100% of the Stated Value
of the Redemption  Shares and (ii) any accrued and unpaid dividends  (whether or
not earned or declared,  whether or not there were funds  legally  available for
the  payment of  dividends  and  whether or not a Dividend  Payment Due Date has
occurred since the last dividend payment) to the date of such redemption.

     (b) Notwithstanding  anything herein to the contrary,  if and to the extent
that,  on any date (the  "Section 16  Determination  Date"),  the holding by the
Holder of shares of the Series C Preferred  Stock would  result in the  Holder's
becoming  subject to the  provisions  of Section  16(b) of the  Exchange  Act in
virtue  of being  deemed  the  "beneficial  owner"  of more than 10% of the then
Outstanding  shares of Common  Stock,  then the Holder shall not have the right,
and the Corporation  shall not have the  obligation,  to convert so many of such
Holder's shares of Series C Preferred Stock (the "Section 16 Redemption Shares")
as shall cause such Holder to be deemed the beneficial owner of more than 10% of
the then  Outstanding  shares of Common Stock  during the period  ending 60 days
after the Section 16  Determination Date. If any court of competent jurisdiction
shall determine that the foregoing limitation is ineffective to prevent a Holder
from being deemed the beneficial  owner of more than 10% of the then Outstanding
shares  of  Common  Stock  for the  purposes  of such  Section  16(b),  then the
Corporation   shall  redeem  the  Section  16  Redemption   Shares.   Upon  such
determination  by a court of competent  jurisdiction,  the Section 16 Redemption
Shares shall  immediately  and without  further action be deemed returned to the
status of authorized but unissued  shares of Series C Preferred  Stock,  and the
Holder  shall have no interest  in or rights  under such  Section 16  Redemption
Shares. Any and all dividends paid on or prior to the date of such determination
shall be deemed  dividends  paid on the  remaining  shares of Series C Preferred
Stock held by the  Holder.  Such  redemption  shall be for cash at a  redemption
price  equal  to the  sum of (i)  100% of the  Stated  Value  of the  Section 16
Redemption Shares and (ii) any declared and unpaid dividends to the date of such
redemption.

     (c) Unless the  Corporation  shall have obtained the approval of its voting
stockholders  to such  issuance  in  accordance  with the rules of Nasdaq or any
other stock market rules with which the Corporation shall be required to comply,
but only to the extent required thereby,  the Corporation shall not issue shares
of Common Stock (i) upon conversion of any shares of Series C Preferred Stock or
(ii) as a dividend on the Series C Preferred  Stock,  if such issuance of Common
Stock,  when added to the number of shares of Common Stock previously  issued by
the Corporation  (x) upon conversion of shares of the Series C Preferred  Stock,
(y) upon exercise of the Warrants issued pursuant to the terms of the Securities
Purchase  Agreement  and (z) in payment of  dividends  on the Series C Preferred
Stock,  would  equal or exceed 20% of the number of shares of the  Corporation's
Common Stock which were issued and  Outstanding  on the Issue Date (the "Maximum
Issuance  Amount").  In the event that a properly executed  Conversion Notice is
received by the Corporation  which would require the Corporation to issue shares
of Common  Stock  equal to or in  excess of the  Maximum  Issuance  Amount,  the
Corporation shall honor such conversion  request by (a) converting the number of
shares of Series C Preferred Stock stated in the Conversion  Notice which is not
in excess of the Maximum  Issuance Amount and (b) redeeming the remaining number
of shares of Series C Preferred Stock stated in the Conversion Notice in cash at
a price equal to 100% of the Stated Value thereof, together with all accrued and
unpaid dividends  (whether or not earned or declared,  whether or not there were
funds  legally  available  for the  payment of  dividends  and  whether or not a
Dividend  Payment Due Date has occurred since the last dividend  payment) on the
total number of shares stated in the  Conversion  Notice.  In the event that the
Corporation  shall elect to pay a dividend in shares of Common Stock which would
require the Corporation to issue shares of Common Stock equal to or in excess of
the  Maximum  Issuance  Amount,  the  Corporation  shall pay (1) a dividend in a
number of shares of Common  Stock  equal to one less than the  Maximum  Issuance
Amount and (2) the balance of the dividend in cash.

                                   ARTICLE 7
                                 Voting Rights

     The Holders of the Series C Preferred Stock have no voting power, except as
otherwise provided by the Business Corporation Law of the State of Massachusetts
(the "MBCL"), in this Article 7, and in Article 8 below.

     Notwithstanding  the above,  the  Corporation  shall provide each Holder of
Series  C  Preferred  Stock  with  prior  notification  of  any  meeting  of the
shareholders  (and copies of all proxy materials and other  information  sent to
shareholders).  In the event of any taking by the Corporation of a record of its
shareholders  for the purpose of  determining  shareholders  who are entitled to
receive  payment of any dividend or other  distribution,  any right to subscribe
for, purchase or otherwise acquire (including by way of merger, consolidation or
recapitalization) any share of any class or any other securities or property, or
to receive any other right, or for the purpose of determining  shareholders  who
are entitled to vote in connection with any proposed liquidation, dissolution or
winding up of the  Corporation,  the Corporation  shall mail a notice thereof to
each Holder at least 30 days prior to the date on which any such record is to be
taken for the  purpose of such  dividend,  distribution,  right or other  event,
together  with a brief  statement  regarding  the amount and  character  of such
dividend, distribution, right or other event to the extent known at such time.

     To the extent  that under the MBCL the vote of the  Holders of the Series C
Preferred  Stock,  voting  separately  as a class or  series as  applicable,  is
required to authorize a given action of the Corporation, the affirmative vote or
consent  of the  Holders  of at least a majority  of the  outstanding  shares of
Series C Preferred Stock represented at a duly held meeting at which a quorum is
present or by written consent of a majority of the outstanding  shares of Series
C Preferred  Stock  (except as otherwise  may be required  under the MBCL) shall
constitute  the  approval of such action by the class.  To the extent that under
the MBCL  Holders  of the Series C  Preferred  Stock are  entitled  to vote on a
matter with holders of Common Stock, voting together as one class, each share of
Series C  Preferred  Stock  shall be  entitled to a number of votes equal to the
number of shares of Common  Stock  into which it is then  convertible  using the
record date for the taking of such vote of  shareholders as the date as of which
the  Conversion  Price is  calculated.  Holders of the Series C Preferred  Stock
shall be entitled to notice of all shareholder meetings or written consents (and
copies of all proxy materials and other  information sent to shareholders)  with
respect to which they would be entitled to vote,  which notice would be provided
pursuant  to the  Corporation's  bylaws  and  the  MBCL.

                                    ARTICLE 8
                              Protective Provisions

     So long as  shares  of  Series  C  Preferred  Stock  are  outstanding,  the
Corporation  shall not, without first obtaining the approval (by vote or written
consent,  as  provided in the MBCL) of the Holders of at least a majority of the
then outstanding shares of Series C Preferred Stock:

     (a) alter or change the rights,  preferences  or privileges of the Series C
Preferred Stock;

     (b)  create any new class or series of capital  stock  having a  preference
over the Series C Preferred Stock as to distribution of assets upon liquidation,
dissolution or winding up of the Corporation  ("Senior  Securities") or alter or
change the rights,  preferences or privileges of any Senior  Securities so as to
affect adversely the Series C Preferred Stock;

(c)   increase the authorized number of shares of Series C Preferred Stock; or

     (d) do any act or thing not authorized or contemplated by this  Certificate
of  Designation  which would  result in taxation of the Holders of shares of the
Series C Preferred Stock under Section 305 of the Internal Revenue Code of 1986,
as amended (or any comparable provision of the Internal Revenue Code of 1986, as
hereafter from time to time amended).

     In the event Holders of least a majority of the then outstanding  shares of
Series C Preferred  Stock agree to allow the  Corporation to alter or change the
rights,  preferences  or  privileges  of the shares of Series  Preferred  Stock,
pursuant to subsection (a) above, so as to affect the Series C Preferred  Stock,
then the Corporation  will deliver notice of such approved change to the Holders
of the Series  Preferred  Stock that did not agree to such  alteration or change
(the  "Dissenting  Holders") and  Dissenting  Holders shall have the right for a
period  of 30 days to  convert  pursuant  to the  terms of this  Certificate  of
Designation  as in effect prior to such  alteration  or change or to continue to
hold their shares of Series C Preferred Stock.

     Notwithstanding  anything  to  the  contrary  herein,  if at any  time  the
Corporation   shall   "spin-off"   certain  of  its  assets  or   businesses  by
transferring,  directly or indirectly, such assets or businesses to a Subsidiary
of the Corporation ("Spinco") and making a dividend (the "Spin-off Dividend") to
the  Corporation's  stockholders of the shares of capital stock of Spinco,  then
prior to making the Spin-off  Dividend,  the  Corporation  shall cause Spinco to
issue to each  Holder that  number of shares of  preferred  stock of Spinco with
substantially identical rights,  preferences,  privileges,  powers, restrictions
and other terms as the Series C Preferred Stock equal to the number of shares of
Series C Preferred Shares held by such Holder  immediately prior to the Spin-off
Dividend.  ARTICLE 9  Miscellaneous  Section  9.1 Loss,  Theft,  Destruction  of
Preferred Stock

     Upon  receipt of  evidence  satisfactory  to the  Corporation  of the loss,
theft,  destruction or mutilation of shares of Series C Preferred  Stock and, in
the case of any such loss,  theft or  destruction,  upon receipt of indemnity or
security reasonably satisfactory to the Corporation, or, in the case of any such
mutilation, upon surrender and cancellation of the Series C Preferred Stock, the
Corporation  shall  make,  issue  and  deliver,  in lieu of such  lost,  stolen,
destroyed or mutilated  shares of Series C Preferred Stock, new shares of Series
C Preferred Stock of like tenor.  The Series C Preferred Stock shall be held and
owned upon the express  condition  that the  provisions  of this Section 9.1 are
exclusive  with respect to the  replacement  of  mutilated,  destroyed,  lost or
stolen shares of Series C Preferred  Stock and shall  preclude any and all other
rights and  remedies  notwithstanding  any law or statute  existing or hereafter
enacted  to  the  contrary  with  respect  to  the   replacement  of  negotiable
instruments or other securities without the surrender thereof.

     Section 9.2 Who Deemed Absolute Owner

     The  Corporation  may deem the Person in whose name the Series C  Preferred
Stock shall be registered  upon the registry books of the Corporation to be, and
may treat it as,  the  absolute  owner of the Series C  Preferred  Stock for the
purpose of receiving  payment of dividends on the Series C Preferred  Stock, for
the conversion of the Series C Preferred Stock and for all other  purposes,  and
the  Corporation  shall not be affected by any notice to the contrary.  All such
payments  and such  conversion  shall be valid  and  effectual  to  satisfy  and
discharge the liability  upon the Series C Preferred  Stock to the extent of the
sum or sums so paid or the conversion so made.

     Section 9.3 Fundamental Corporate Change

     In the case of the occurrence of any Fundamental Corporate Change described
in Section 5(b), the  Corporation  shall cause to be mailed to the Holder of the
Series C Preferred Stock at its last address as it appears in the  Corporation's
security registry, at least 20 days prior to the applicable record, effective or
expiration date specified in connection therewith (or, if such 20 days notice is
not possible, at the earliest possible date prior to any such record,  effective
or expiration  date),  a notice  stating (x) the date on which a record is to be
taken for the  purpose  of such  corporate  action,  or if a record is not to be
taken, the date as of which the Holders of record of Series C Preferred Stock to
be  entitled  to any  dividend,  distribution,  issuance  or granting of rights,
options or warrants are to be determined  or the date on which such  Fundamental
Corporate Change is expected to become  effective,  and (y) the date as of which
it is  expected  that  Holders  of record of Series C  Preferred  Stock  will be
entitled  to  exchange  their  shares  for  securities,  cash or other  property
deliverable upon such Fundamental Corporate Change.

     Section 9.4 Register

     The Corporation  shall keep at its principal office a register in which the
Corporation  shall provide for the registration of the Series C Preferred Stock.
Upon any  transfer  of the  Series C  Preferred  Stock  in  accordance  with the
provisions  hereof, the Corporation shall register such transfer on the register
of Series C Preferred Stock.

Section 9.5 Withholding

     To the extent  required by  applicable  law, the  Corporation  may withhold
amounts for or on account of any taxes  imposed or levied by or on behalf of any
taxing authority in the United States having  jurisdiction  over the Corporation
from any payments  made  pursuant to the Series C Preferred  Stock.  Section 9.6
Headings

     The  headings  of  the  Articles  and  Sections  of  this   Certificate  of
Designation  are inserted for  convenience  only and do not constitute a part of
this Certificate of Designation. Section 9.7 Severability

     If any provision of this  Certificate of  Designation,  or the  application
thereof   to  any  person  or  entity  or  any   circumstance,   is  invalid  or
unenforceable,  (i) a  suitable and  equitable  provision  shall be  substituted
therefor  in order to carry  out,  so far as may be valid and  enforceable,  the
intent and purpose of such  invalid or  unenforceable  provision,  and  (ii) the
remainder  of  this  Certificate  of  Designation  and the  application  of such
provision to other persons,  entities or circumstances  shall not be affected by
such   invalidity   or   unenforceability,   nor  shall   such   invalidity   or
unenforceability affect the validity or enforceability of such provision, or the
application thereof, in any other jurisdiction.

                          [SIGNATURE PAGE FOLLOWS.]




     In Witness  Whereof,  the  Corporation has caused this amended and Restated
Certificate of Designation to be signed by its duly authorized officers on as of
February 14, 2001.
