EXHIBIT 3.2
                         CERTIFICATE OF DESIGNATION OF
                            SERIES F PREFERRED STOCK

                                       OF

                          LIGHTPATH TECHNOLOGIES, INC.

It is hereby certified that:

     1. The name of the Company  (hereinafter called the "Company") is LightPath
Technologies, Inc., a Delaware corporation.

     2. The certificate of incorporation of the Company  authorizes the issuance
of five million (5,000,000) shares of preferred stock, $.01 par value per share,
and  expressly  vests in the Board of  Directors  of the Company  the  authority
provided  therein to issue any or all of said  shares in one (1) or more  series
and by resolution or resolutions to establish the  designation and number and to
fix the relative rights and preferences of each series to be issued.

     3.  The  Board of  Directors  of the  Company,  pursuant  to the  authority
expressly  vested in it as  aforesaid,  has  adopted the  following  resolutions
creating a Series F issue of Preferred Stock:

     RESOLVED,   that  five  hundred  (500)  of  the  five  million  (5,000,000)
authorized shares of Preferred Stock of the Company shall be designated Series F
Preferred  Stock,  $.01 par value per share,  and shall  possess  the rights and
preferences set forth below:

     Section 1.  DESIGNATION AND AMOUNT.  The shares of such series shall have a
par value of $.01 per share and shall be designated as Series F Preferred  Stock
(the "Series F Preferred  Stock," or the  "Preferred  Shares") and the number of
shares  constituting  the Series F Preferred  Stock shall be five hundred (500).
The  Series F  Preferred  Stock  shall be  offered  at a  purchase  price of Ten
Thousand Dollars ($10,000) per share (the "Original Series F Issue Price"), with
a seven percent (7%) per annum accretion rate as set forth herein.

     Section 2. RANK. The Series F Preferred Stock shall rank: (i) junior to any
other  class or  series  of  capital  stock  of the  Company  hereafter  created
specifically  ranking  by its  terms  senior  to the  Series F  Preferred  Stock
(collectively,  the  "Senior  Securities");  (ii) prior to all of the  Company's
Class A, Class E-1,  Class E-2,  and Class E-3 Common  Stock,  all at a $.01 par
value per share ("Common Stock");  (iii) prior to any class or series of capital
stock of the Company  hereafter  created not  specifically  ranking by its terms
senior to or on parity with any Series F Preferred Stock of whatever subdivision
(collectively,  with the Common Stock, "Junior Securities");  and (iv) on parity
with the Series A Preferred Stock,  Series B Preferred Stock, Series C Preferred
Stock, Series D Preferred Stock and with any class or series of capital stock of
the Company hereafter created  specifically  ranking by its terms on parity with
the  Series  F  Preferred  Stock  ("Parity  Securities")  in  each  case  as  to
distributions  of assets  upon  liquidation,  dissolution  or  winding up of the
Company, whether voluntary or involuntary (all such distributions being referred
to collectively as "Distributions").

     Section 3. DIVIDENDS.  The Series F Preferred Stock will bear no dividends,
and the  holders  of the  Series F  Preferred  Stock  ("Holders")  shall  not be
entitled to receive dividends on the Series F Preferred Stock.

     Section 4. LIQUIDATION PREFERENCE.

          (a) In the event of any liquidation,  dissolution or winding up of the
Company ("Liquidation Event"), either voluntary or involuntary, the then Holders
of shares of Series F Preferred Stock shall be entitled to receive,  immediately
after  any  distributions  to  Senior  Securities   required  by  the  Company's
Certificate of  Incorporation  or any certificate of  designation,  and prior in
preference  to any  distribution  to Junior  Securities  but in parity  with any
distribution to Parity  Securities,  an amount per share equal to the sum of (i)
the  Original  Series F Issue  Price  for  each  outstanding  share of  Series F
Preferred  Stock and (ii) an amount equal to seven  percent (7%) of the Original
Series F Issue Price, per annum,  accruing daily, for the period that has passed
since the date that,  in  connection  with the  consummation  of the purchase by
Holder of shares of Series F Preferred Stock from the Company,  the escrow agent
first had in its possession  funds  representing  full payment for the shares of
Series  F  Preferred  Stock  (such  amount  being  referred  to  herein  as  the
"Premium").  If upon the occurrence of such event,  and after payment in full of
the preferential  amounts with respect to the Senior Securities,  the assets and
funds  available to be  distributed  among the Holders of the Series F Preferred
Stock and Parity  Securities shall be insufficient to permit the payment to such
Holders  of the full  preferential  amounts  due to the  Holders of the Series F
Preferred Stock and the Parity Securities,  respectively, then the entire assets
and funds of the Company legally available for distribution shall be distributed
among the Holders of the Series F Preferred Stock and the Parity Securities, pro
rata, based on the respective  liquidation  amounts to which each such series of
stock  is  entitled  by the  Company's  Certificate  of  Incorporation  and  any
certificate(s) of designation relating thereto.

          (b) Upon the  completion  of the  distribution  required by subsection
4(a), if assets remain in this Company,  they shall be distributed to holders of
Junior Securities in accordance with the Company's  Certificate of Incorporation
including any duly adopted certificate(s) of designation.

          (c) At each Holder's option, 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
fifty  percent  (50%) of the voting power of the Company is disposed of shall be
deemed to be a Liquidation  Event as defined in Section 4(a);  provided  further
that (i) a consolidation,  merger, acquisition, or other business combination of
the Company with or into any other publicly  traded  company or companies  shall
not be treated as a  Liquidation  Event as defined in Section  4(a) but  instead
shall be treated  pursuant to Section  5(d)  hereof,  and (ii) a  consolidation,
merger,  acquisition,  or other business combination of the Company with or into
any other non-publicly traded company or companies in which the surviving entity
is not a publicly  traded  company  shall be treated as a  Liquidation  Event as
defined in Section 4(a). The Company shall not effect any transaction  described
in  subsection  4(c)(ii)  unless it first gives thirty (30)  business days prior
notice of such  transaction  during  which time the Holder  shall be entitled to
immediately  convert any or all of its shares of Series F  Preferred  Stock into
Class A Common Stock at the Conversion  Price, as defined below, then in effect,
which conversion  shall not be subject to the conversion  restrictions set forth
in Section 5(a).

                                       2

          (d)  In  the  event  that,  immediately  prior  to  the  closing  of a
transaction  described  in Section  4(c) which would  constitute  a  Liquidation
Event,  the cash  distributions  required by Section  4(a) or Section 6 have not
been made,  the Company  shall  either:  (i) cause such closing to be reasonably
postponed  until  such cash  distributions  have been  made,  (ii)  cancel  such
transaction,  in which  event the rights of the  Holders  of Series F  Preferred
Stock  shall  be the  same  as  existing  immediately  prior  to  such  proposed
transaction  or (iii)  agree,  and  shall  require  that any  successor  company
resulting from a Liquidation Event agrees, to make such distributions as quickly
after the closing of such Liquidation Event as reasonably practicable,  upon the
same  terms  and in the same  amounts  as the  Company  would  have made if such
distribution was made immediately prior to the closing of such transaction.

     Section 5. CONVERSION.  Subject to Section 4(c) herein,  the record Holders
of this Series F Preferred  Stock shall have  conversion  rights as follows (the
"Conversion Rights"):

          (a) RIGHT TO  CONVERT.  The record  Holder of the  Series F  Preferred
Stock shall be entitled to convert and the conversion restrictions herein below,
any or all the aggregate  principal amount of the Series F Preferred Stock on or
after the date that is four (4) months after the Last Closing  Date,  as defined
below,  at the  office of the  Company  or its  designated  transfer  agent (the
"Transfer Agent"),  into that number of fully-paid and non-assessable  shares of
Class A Common Stock  calculated in accordance  with the following  formula (the
"Conversion Rate"):

         Number of shares of Class A Common Stock issued upon  conversion of one
(1) share of Series F Preferred Stock =

                         (.07) (N/365) (10,000) + 10,000
                         -------------------------------
                                Conversion Price

          where,

          * N= the number of days between (i) the date that, in connection  with
          the consummation of the initial purchase by Holder of shares of Series
          F Preferred Stock from the Company,  the escrow agent first had in its
          possession funds  representing full payment for the shares of Series F
          Preferred  Stock for which  conversion is being elected,  and (ii) the
          applicable  Date of Conversion (as defined in Section  5(b)(iv) below)
          for the shares of Series F  Preferred  Stock for which  conversion  is
          being elected, and

          *  CONVERSION  PRICE = the lesser of (x) $5.00 (the "Fixed  Conversion
          Price"),  or (y) 80% of the average Closing Bid Price, as that term is
          defined below,  of the Company's Class A Common Stock for the five (5)
          trading days immediately preceding the Date of Conversion,  as defined
          below (the "Variable Conversion Price"),

provided,  however,  that, unless otherwise  indicated herein,  beginning on the
date that is four (4) months  following the Last Closing Date, as defined below,
the right of the Holder to convert  into Class A Common Stock using the Variable
Conversion Price initially shall be limited to a maximum of twenty percent (20%)
of the aggregate principal amount of the Series F Preferred Stock issued to such
Holder, and for each one (1) month period which expires  thereafter,  the Holder
shall accrue the right to convert into Class A Common Stock an additional twenty

                                       3

percent (20%) of the aggregate  principal amount of the Series F Preferred Stock
issued to such Holder,  (the number of shares that may be converted at any given
time using the  Variable  Conversion  Price,  in the  aggregate,  is referred to
hereinafter as the "Conversion Quota"); and provided, further, in the event that
the Holder  elects not to convert its full  Conversion  Quota during any one (1)
month period,  the unconverted  amount shall be carried forward and added to the
Conversion Quota, and thereafter the Holder may, from time to time,  convert any
portion of the Conversion Quota at the Variable  Conversion Price; and provided,
further,  that subsequent to the date that is nine (9) months following the Last
Closing Date, there shall be no restrictions on the number of shares of Series F
Preferred  Stock  that may be  converted  into  Class A Common  Stock  using the
Variable Conversion Price; and provided,  further, that a Holder can convert one
hundred percent (100%) of the Series F Preferred  Stock, or any portion thereof,
into Class A Common Stock using the Fixed  Conversion Price on or after the date
that is four (4) months  after the Last  Closing  Date  whether or not the Fixed
Conversion Price is less than the Variable Conversion Price.

     As used herein, "Last Closing Date" shall mean the date of the last closing
of a purchase and sale of the Series F Preferred  Stock that occurs  pursuant to
the offering of the Series F Preferred Stock by the Company.

     For purposes hereof, any Holder which acquires shares of Series F Preferred
Stock from another Holder (the "Transferor") and not upon original issuance from
the  Company  shall be  entitled  to  exercise  its  conversion  right as to the
percentages of such shares  specified  under Section 5(a) in such amounts and at
such times such that the number of shares eligible for conversion by such Holder
at any time shall be in the same  proportion that the number of shares of Series
F Preferred Stock acquired by such Holder from its Transferor bears to the total
number of shares of Series F Preferred Stock originally issued by the Company to
such Transferor (or its predecessor Transferor).

     For purposes  hereof,  the term  "Closing Bid Price" shall mean the closing
bid price of the Company's  Class A Common Stock on the Nasdaq Small Cap Market,
or if no longer traded on the Nasdaq Small Cap Market,  the closing bid price on
the principal national securities exchange or the  over-the-counter on which the
Class A Common Stock is so traded and if not available, the mean of the high and
low prices on the principal national securities exchange or the over-the-counter
system on which the Class A Common Stock is so traded.

          (b) MECHANICS OF  CONVERSION.  In order to convert  Series F Preferred
Stock into full shares of Class A Common  Stock,  the Holder  shall (i) send via
facsimile, on or prior to 11:59 p.m., New York City time (the "Conversion Notice
Deadline") on the Date of  Conversion,  a copy of the fully  executed  notice of
conversion  ("Notice of Conversion") to the Company at the office of the Company
and to its designated  transfer  agent (the  "Transfer  Agent") for the Series F
Preferred  Stock stating that the Holder  elects to convert,  which notice shall
specify the Date of Conversion, the number of shares of Series F Preferred Stock
to be converted, the applicable Conversion Price and a calculation of the number
of shares of Class A Common Stock issuable upon such conversion (together with a
copy of the front page of each  certificate  to be converted) and (ii) surrender
to a common  courier for  delivery to the office of the Company or the  Transfer
Agent, the original certificates representing the Series F Preferred Stock being
converted  (the  "Preferred  Stock  Certificates"),  duly endorsed for transfer;
provided, however, that the Company shall not be obligated to issue certificates
evidencing  the shares of Class A Common  Stock  issuable  upon such  conversion
unless either the Preferred Stock  Certificates  are delivered to the Company or
its Transfer Agent as provided  above, or the Holder notifies the Company or its
Transfer  Agent  that such  certificates  have been  lost,  stolen or  destroyed

                                       4

(subject to the  requirements  of subparagraph  (i) below).  Upon receipt by the
Company  of a  facsimile  copy of a Notice  of  Conversion,  the  Company  shall
immediately  send,  via facsimile,  a  confirmation  of receipt of the Notice of
Conversion to Holder which shall specify that the Notice of Conversion  has been
received and the name and  telephone  number of a contact  person at the Company
whom the Holder should contact regarding  information related to the Conversion.
In the case of a dispute  as to the  calculation  of the  Conversion  Rate,  the
Company  shall  promptly  issue to the Holder the number of Shares  that are not
disputed and shall submit the disputed  calculations  to its outside  accountant
via facsimile within three (3) days of receipt of Holder's Notice of Conversion.
The Company shall cause the  accountant to perform the  calculations  and notify
the Company and Holder of the results no later than two  business  days from the
time it receives the disputed  calculations.  Accountant's  calculation shall be
deemed conclusive absent manifest error.

               (i) LOST OR STOLEN  CERTIFICATES.  Upon receipt by the Company of
evidence of the loss,  theft,  destruction or mutilation of any Preferred  Stock
Certificates  representing  shares of Series F Preferred Stock, and (in the case
of loss, theft or destruction) of indemnity or security reasonably  satisfactory
to the Company,  and upon  surrender and  cancellation  of the  Preferred  Stock
Certificate(s),  if  mutilated,  the  Company  shall  execute  and  deliver  new
Preferred  Stock  Certificate(s)  of like tenor and date.  However,  the Company
shall  not be  obligated  to  re-issue  such  lost  or  stolen  Preferred  Stock
Certificates  if Holder  contemporaneously  requests the Company to convert such
Series F Preferred Stock into Class A Common Stock.

               (ii) DELIVERY OF COMMON STOCK UPON CONVERSION.  The Company shall
or shall cause the Transfer Agent to, no later than the close of business on the
second (2nd) business day (the  "Deadline")  after receipt by the Company or the
Transfer  Agent of a  facsimile  copy of a Notice of  Conversion  and receipt by
Company or the Transfer Agent of all necessary  documentation  duly executed and
in proper form required for conversion,  including the original  Preferred Stock
Certificates to be converted (or after provision for security or indemnification
in the case of lost or destroyed certificates, if required), issue and surrender
to a common  courier for either  overnight or (if delivery is outside the United
States) two (2) day delivery to the Holder at the address of the Holder as shown
on the stock  records of the Company a  certificate  for the number of shares of
Class A Common Stock to which the Holder shall be entitled as aforesaid.

               (iii) NO  FRACTIONAL  SHARES.  If any  conversion of the Series F
Preferred  Stock would  create a  fractional  share of Class A Common Stock or a
right to acquire a fractional  share of Class A Common  Stock,  such  fractional
share  shall be  disregarded  and the  number of shares of Class A Common  Stock
issuable upon conversion,  in the aggregate,  shall be the next higher number of
shares.

               (iv) DATE OF CONVERSION. The date on which conversion occurs (the
"Date of Conversion") shall be deemed to be the date set forth in such Notice of
Conversion,  provided (i) that the advance copy of the Notice of  Conversion  is
sent via facsimile to the Company  before 11:59 p.m., New York City time, on the
Date of  Conversion,  and (ii) that the original  Preferred  Stock  Certificates
representing  the  shares  of  Series  F  Preferred  Stock to be  converted  are
surrendered by depositing such certificates with a common courier,  for delivery
to the Company or the Transfer Agent as provided  above,  as soon as practicable
after the Date of  Conversion.  The person or persons  entitled  to receive  the

                                       5

shares of Class A Common Stock  issuable upon such  conversion  shall be treated
for all  purposes  as the record  Holder or  Holders  of such  shares of Class A
Common Stock on the Date of Conversion.

          (c)  AUTOMATIC  CONVERSION  OR  REDEMPTION.  Each  share  of  Series F
Preferred Stock  outstanding on the date which is three (3) years after the Last
Closing  Date or, if not a  business  day,  the first  business  day  thereafter
("Termination Date")  automatically shall, at the option of the Company,  either
(i) be converted ("Automatic Conversion") into Class A Common Stock on such date
at the Conversion Rate then in effect (calculated in accordance with the formula
in Section 5(a)  above),  and the  Termination  Date shall be deemed the Date of
Conversion with respect to such  conversion for purposes of this  Certificate of
Designation,  or (ii) be redeemed  ("Automatic  Redemption")  by the Company for
cash in an amount  equal to the Stated  Value (as  defined  in  Section  6(b)(i)
below) of the shares of Series F Preferred Stock being redeemed.  If the Company
elects to redeem, on the Termination Date, the Company shall send to the Holders
of  outstanding  Series F  Preferred  Stock  notice (the  "Automatic  Redemption
Notice") via  facsimile of its intent to effect an Automatic  Redemption  of the
outstanding  Series F Preferred  Stock. If the Company does not send such notice
to  Holder  on such  date,  an  Automatic  Conversion  shall be  deemed  to have
occurred.  If an Automatic  Conversion occurs, the Company and the Holders shall
follow the applicable  conversion  procedures  set forth in this  Certificate of
Designation;  provided,  however,  that the Holders are not required to send the
Notice of Conversion  contemplated  by Section  5(b).  If the Company  elects to
redeem,  each Holder of  outstanding  Series F Preferred  Stock shall send their
certificates  representing  the Series F Preferred  Stock to the Company  within
five (5) days of the date of receipt of the Automatic Redemption Notice from the
Company,  and the  Company  shall pay the  applicable  redemption  price to each
respective Holder within five (5) days of the receipt of such certificates.  The
Company  shall not be  obligated  to deliver  the  redemption  price  unless the
certificates  representing  the Series F Preferred  Stock are  delivered  to the
Company,  or, in the  event one or more  certificates  have been  lost,  stolen,
mutilated or destroyed,  unless the Holder has complied with Section 5(b)(i). If
the Company  elects to redeem under this  Section 5(c) and the Company  fails to
pay the Holders the redemption  price within five (5) days of its receipt of the
certificates  representing the shares of Series F Preferred Stock to be redeemed
as required by this Section 5(c), then an Automatic  Conversion  shall be deemed
to have  occurred and, upon receipt of the  Preferred  Stock  certificates,  the
Company shall immediately  deliver to the Holders the certificates  representing
the  number of shares of Class A Common  Stock to which the  Holders  would have
been entitled upon Automatic Conversion.

          (d) ADJUSTMENT TO CONVERSION RATE.

               (i)  ADJUSTMENT  TO FIXED  CONVERSION  PRICE DUE TO STOCK  SPLIT,
STOCK  DIVIDEND,  ETC.  If,  prior  to the  conversion  of all of the  Series  F
Preferred  Stock,  the number of  outstanding  shares of Class A Common Stock is
increased by a stock split,  stock dividend,  or other similar event,  the Fixed
Conversion  Price  shall  be  proportionately  reduced,  or  if  the  number  of
outstanding   shares  of  Common  Stock  is  decreased  by  a   combination   or
reclassification  of shares,  or other similar event, the Fixed Conversion Price
shall be proportionately increased.

               (ii)  ADJUSTMENT TO VARIABLE  CONVERSION  PRICE.  If, at any time
when any shares of the Series F Preferred Stock are issued and outstanding,  the
number of  outstanding  shares of Class A Common Stock is increased or decreased
by a stock split, stock dividend, or other similar event, which event shall have

                                       6

taken place during the  reference  period for  determination  of the  Conversion
Price for any  conversion  of the Series F Preferred  Stock,  then the  Variable
Conversion  Price shall be  calculated  giving  appropriate  effect to the stock
split, stock dividend, combination,  reclassification or other similar event for
all five (5) trading days immediately preceding the Date of Conversion.

               (iii) ADJUSTMENT DUE TO MERGER, CONSOLIDATION,  ETC. If, prior to
the  conversion  of all Series F  Preferred  Stock,  there  shall be any merger,
consolidation,  exchange of shares, recapitalization,  reorganization,  or other
similar  event,  as a result  of  which  shares  of Class A Common  Stock of the
Company  shall be changed  into the same or a different  number of shares of the
same or  another  class or  classes  of stock or  securities  of the  Company or
another  entity  or there is a sale of all or  substantially  all the  Company's
assets  or  there  is a  change  of  control  transaction  not  deemed  to  be a
liquidation  pursuant  to Section  4(c),  then the Holders of Series F Preferred
Stock shall  thereafter  have the right to receive upon  conversion  of Series F
Preferred  Stock,  upon the basis and upon the  terms and  conditions  specified
herein and in lieu of the shares of Class A Common Stock immediately theretofore
issuable upon conversion,  such stock,  securities and/or other assets which the
Holder would have been entitled to receive in such  transaction had the Series F
Preferred Stock been converted immediately prior to such transaction, and in any
such case  appropriate  provisions  shall be made with respect to the rights and
interests  of the  Holders of the Series F  Preferred  Stock to the end that the
provisions hereof (including, without limitation,  provisions for the adjustment
of the Conversion  Price and of the number of shares issuable upon conversion of
the Series F Preferred Stock) shall  thereafter be applicable,  as nearly as may
be  practicable in relation to any securities  thereafter  deliverable  upon the
exercise hereof. The Company shall not effect any transaction  described in this
subsection  5(d)(iii)  unless (a) it first gives at least thirty (30) days prior
notice of such  merger,  consolidation,  exchange  of shares,  recapitalization,
reorganization,  or other  similar  event (during which time the Holder shall be
entitled to convert  its shares of Series F Preferred  Stock into Class A Common
Stock) and (b) the resulting  successor or acquiring entity (if not the Company)
assumes  by  written  instrument  the  obligations  of the  Company  under  this
Certificate of Designation including this subsection 5(d)(iii).

               (iv) NO FRACTIONAL  SHARES.  If any adjustment under this Section
5(d)  would  create a  fractional  share  of Class A Common  Stock or a right to
acquire a fractional share of Class A Common Stock,  such fractional share shall
be  disregarded  and the number of shares of Class A Common Stock  issuable upon
conversion shall be the next higher number of shares.

     Section 6. Company's  Right to Redeem at Its Election.  Subject to Sections
6(iv) and 6(v) below,  the Company shall have the right, in its sole discretion,
to redeem  ("Redemption at the Company's  Election"),  from time to time, any or
all of the Preferred  Shares at the Redemption  Price at the Company's  Election
(as defined  below).  If the Company  elects to redeem some, but not all, of the
Preferred Shares, the Company shall redeem a pro rata amount from each holder of
Preferred  Shares  based on the number of  Preferred  Shares held by such holder
relative to the number of Preferred Shares outstanding.

               (i) Redemption Price at the Company's  Election.  The "Redemption
Price at the Company's Election" shall be an amount per Preferred Share equal to
the product of (A) 1.3  multiplied  by (B) the sum of (I)  (.07)(P/365)($10,000)
plus (II) $10,000;  where "P" means the number of days from, but excluding,  the
issuance  date of  such  Preferred  Share  through  and  including  the  Date of
Redemption at the Company's Election (as defined in Section 6(ii)).

                                       7

               (ii)  Mechanics of  Redemption  at the  Company's  Election.  The
Company  shall  effect each such  redemption  no sooner than 20 trading days nor
later than 40 trading days after delivering  written notice of its Redemption at
the  Company's   Election  via  facsimile  and  overnight  courier  ("Notice  of
Redemption  at the  Company's  Election")  to (A) each  holder of the  Preferred
Shares and (B) the Transfer  Agent.  Such Notice of  Redemption at the Company's
Election  shall  indicate  (I) the  number of  Preferred  Shares  that have been
selected  for  redemption,  (II) the date  that  such  redemption  is to  become
effective  (the "Date of Redemption at the  Company's  Election")  and (III) the
applicable  Redemption  Price at the  Company's  Election.  Notwithstanding  the
above,  any holder may convert  into Common  Stock  pursuant to Section 5, on or
prior to the date immediately  preceding the Date of Redemption at the Company's
Election,  any  Preferred  Shares held by such holder (and,  after such holder's
receipt of the Notice of Redemption at the Company's Election, without regard to
the conversion  limitations set forth in Section 5), including  Preferred Shares
that have been selected for  Redemption at the  Company's  Election  pursuant to
this Section 6.

               (iii)  Payment  of  Redemption   Price.  Each  holder  submitting
Preferred  Shares being  redeemed  under this Section 6 shall send such holder's
Preferred  Stock  Certificates so redeemed to the Transfer Agent within five (5)
business days after the Date of Redemption  at the Company's  Election,  and the
Company shall pay the applicable  Redemption Price at the Company's  Election to
that holder in cash within three (3) business days after such holder's Preferred
Stock  Certificates  are delivered to the Company or its Transfer  Agent. If the
Company  shall  fail to pay the  applicable  Redemption  Price at the  Company's
Election to such holder on a timely basis as  described in this Section  6(iii),
in addition to any remedy  such holder of  Preferred  Shares may have under this
Certificate of Designations and the Subscription Agreement, the Fixed Conversion
Price and Variable  Conversion Price shall each be automatically  reduced by ten
percent (10%).  Notwithstanding  the foregoing,  if the Company fails to pay the
applicable  Redemption  Price at the  Company's  Election to a holder within the
time period  described in this  Section 6 due to a dispute as to the  arithmetic
calculation  of the  Redemption  Price at the Company's  Election,  such dispute
shall be resolved pursuant to Section 5(b) above.

               (iv)  Company  Must Have  Immediately  Available  Funds or Credit
Facilities.  The Company  shall not be entitled to send any Notice of Redemption
at the  Company's  Election  pursuant  to  Section  6(ii)  above  and  begin the
redemption procedure under this Section 6, unless it has:

                    (A) the full amount of the Redemption Price at the Company's
Election in cash,  available in a demand or other immediately  available account
in a bank or similar financial institution;

                    (B)  credit  facilities,  with a bank or  similar  financial
institutions  that  are  immediately  available  and  unrestricted  for  use  in
redeeming the Preferred  Shares,  in the full amount of the Redemption  Price at
the Company's Election;

                    (C) a  written  agreement  with  a  standby  underwriter  or
qualified  buyer  ready,  willing  and  able to  purchase  from  the  Company  a
sufficient number of shares of stock to provide proceeds necessary to redeem any
stock that is not converted prior to a Redemption at the Company's Election; or

                                       8

                    (D) a  combination  of the items set forth in the  preceding
clauses (A), (B) and (C), aggregating the full amount of the Redemption Price at
the Company's Election.

               (v) Certain  Conditions  During Notice Period.  The Company shall
not be entitled to redeem the  Preferred  Shares on a Date of  Redemption at the
Election of the Company,  unless each of the following  conditions are satisfied
as of the date of the Notice of Redemption at the Company's Election and on each
day from such date until and  including  the later of the Date of  Redemption at
the  Company's  Election and the date on which the Company  pays the  applicable
Redemption Price:

                    (A)  The  Registration  Statement  shall  be  effective  and
available  for the sale of no less  than  100% of the sum of (I) the  number  of
shares of common stock then  issuable  upon the  conversion  of all  outstanding
Preferred  Shares  and (II) the number of shares of common  stock then  issuable
upon  exercise of all  outstanding  warrants  held by the  holders of  Preferred
Shares;

                    (B) The Common  Stock is  designated  for  quotation  on the
Nasdaq National Market,  Nasdaq Small-Cap  Market,  The New York Stock Exchange,
Inc. or The American Stock Exchange, Inc. and is not suspended from trading;

                    (C) The Company has  delivered  shares of common  stock upon
conversion  of the  Preferred  Shares and exercise of the  warrants  held by the
holders of Preferred Shares to the holders of Preferred Shares on a timely basis
as set forth in Section 5 of this  Certificate of Designations  and as set forth
in the warrants held by such holders, respectively; and

                    (D) The Company  otherwise has satisfied its obligations and
is not in default  under this  Certificate  of  Designations,  the  Subscription
Agreement,  the  warrants  held  by the  holders  of  Preferred  Shares  and the
Registration Rights Agreement.

     Section 7. VOTING RIGHTS. The Holders of the Series F Preferred Stock shall
have no voting power  whatsoever,  except as  otherwise  provided by the General
Corporation  Law of the State of  Delaware  ("Delaware  Law"),  and no Holder of
Series F Preferred  Stock shall vote or otherwise  participate in any proceeding
in which actions shall be taken by the Company or the shareholders thereof or be
entitled to notification as to any meeting of the shareholders.

     Notwithstanding   the  above,   the  Company  shall  provide   Holder  with
notification  of any meeting of the  shareholders  regarding any major corporate
events  affecting  the  Company.  In the event of any taking by the Company 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 any share of any class or any other
securities  or  property   (including  by  way  of  merger,   consolidation   or
reorganization),  or  to  receive  any  other  right,  or  for  the  purpose  of
determining  shareholders  who  are  entitled  to vote in  connection  with  any
proposed sale, lease or conveyance of all or substantially  all of the assets of
the  Company,  or any  proposed  liquidation,  dissolution  or winding up of the

                                       9

Company, the Company shall mail a notice to Holder, at least ten (10) days prior
to the record date specified therein, of the date on which any such record is to
be taken for the purpose of such dividend,  distribution,  right or other event,
and 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 Delaware Law the vote of the Holders of the Series
F Preferred  Stock,  voting  separately  as a class,  is required to authorize a
given action of the Company,  the affirmative  vote or consent of the Holders of
at least a majority of the shares of the Series F Preferred Stock represented at
a duly held  meeting at which a quorum is  present  or by  written  consent of a
majority of the shares of Series F Preferred  Stock  (except as otherwise may be
required under Delaware Law) shall constitute the approval of such action by the
class.  To the  extent  that  under  Delaware  Law the  Holders  of the Series F
Preferred  Stock are entitled to vote on a matter with holders of Class A Common
Stock,  voting together as one (1) class, each share of Series F Preferred Stock
shall be  entitled to a number of votes equal to the number of shares of Class A
Common  Stock into which it is then  convertible  using the record  date for the
taking of such vote of stockholders as the date as of which the Conversion Price
is calculated. Holders of the Series F Preferred Stock also shall be entitled to
notice of all  shareholder  meetings or written  consents  with respect to which
they would be entitled to vote,  which notice would be provided  pursuant to the
Company's by-laws and applicable statutes.

     Section 8.  PROTECTIVE  PROVISION.  So long as shares of Series F Preferred
Stock are  outstanding,  the  Company  shall not  without  first  obtaining  the
approval  (by vote or written  consent,  as  provided  by  Delaware  Law) of the
Holders of at least seventy-five percent (75%) of the then outstanding shares of
Series F Preferred  Stock, and at least  seventy-five  percent (75%) of the then
outstanding Holders:

                  (a) alter or change the rights,  preferences  or privileges of
the Series F Preferred  Stock or any  securities  so as to affect  adversely the
Series F Preferred Stock;

                  (b)  create  any  new  class  or  series  of  stock  having  a
preference  over or on parity with the Series F Preferred  Stock with respect to
Distributions  (as  defined  in  Section  2 above) or  increase  the size of the
authorized number of Series F Preferred; or

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

     In the event  Holders of at least  seventy-five  percent  (75%) of the then
outstanding shares of Series F Preferred Stock and at least seventy-five percent
(75%) of the then  outstanding  Holders  agree to allow the  Company to alter or
change the rights, preferences or privileges of the shares of Series F Preferred
Stock,  pursuant to subsection (a) above, so as to affect the Series F Preferred
Stock,  then the Company  will  deliver  notice of such  approved  change to the
Holders of the Series F 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 thirty (30)  business  days to convert  pursuant to the terms of
this Certificate of Designation as they exist prior to such alteration or change
(notwithstanding  the holding requirements set forth in Section 5(a) hereof), or
continue to hold their shares of Series F Preferred Stock, as amended.

                                       10

     Section 9. STATUS OF CONVERTED OR REDEEMED  STOCK.  In the event any shares
of Series F Preferred Stock shall be converted or redeemed pursuant to Section 5
or Section 6 hereof,  the shares so  converted  or redeemed  shall be  canceled,
shall  return to the status of  authorized  but unissued  Preferred  Stock of no
designated  series,  and  shall  not be  issuable  by the  Company  as  Series F
Preferred Stock.

     Section 10. PREFERENCE RIGHTS.  Nothing contained herein shall be construed
to prevent the Board of  Directors  of the Company  from issuing one (1) or more
series of Preferred Stock with dividend and/or liquidation preferences junior to
the dividend and liquidation preferences of the Series F Preferred Stock.

     Section 11. AUTHORIZATION AND RESERVATION OF SHARES OF COMMON STOCK.

          (a) AUTHORIZED AND RESERVED AMOUNT.  The Company shall have authorized
and  reserved  and  keep   available  for  issuance  one  million  nine  hundred
twenty-five  thousand  (1,925,000) shares of Class A Common Stock (the "Reserved
Amount")  solely for the purpose of  effecting  the  conversion  of the Series F
Preferred  Stock,  and exercise of the warrants to acquire  Class A Common Stock
(the "Common Warrants") issued or to be issued to the Holders. The Company shall
at all times  reserve and keep  available  out of its  authorized  but  unissued
shares of Class A Common Stock a  sufficient  number of shares of Class A Common
Stock to provide for the full conversion of all  outstanding  Series F Preferred
Stock,  and  issuance  of the  shares  of  Class A Common  Stock  in  connection
therewith  and the full  exercise  of the Common  Warrants  and  issuance of the
shares of Class A Common Stock in connection therewith.

          (b) INCREASES TO RESERVED AMOUNT. Without limiting any other provision
of this Section 11, if the Reserved Amount for any three (3) consecutive trading
days (the last of such three (3)  trading  days being the  "Reservation  Trigger
Date") shall be less than one hundred  twenty-five  percent (125%) of the number
of shares of Class A Common  Stock  issuable  upon  conversion  of this Series F
Preferred  Stock,  and one  hundred  percent  of the number of shares of Class A
Common Stock issuable upon exercise of the Common  Warrants on such trading days
(a "Share  Authorization  Failure"),  the Company shall  immediately  notify all
Holders of such occurrence and shall take action as soon as possible, but in any
event within sixty (60) days after a  Reservation  Trigger Date  (including,  if
necessary,  seeking shareholder approval to authorize the issuance of additional
shares of Class A Common  Stock) to increase the Reserved  Amount to one hundred
fifty  percent  (150%) of the  number of  shares  of Class A Common  Stock  then
issuable  upon  conversion  of the Series F  Preferred  Stock,  and one  hundred
percent of the number of shares of Class A Common Stock  issuable  upon exercise
of the Common Warrants.

          (c) REDUCTION OF RESERVED AMOUNT UNDER CERTAIN CIRCUMSTANCES. Prior to
complete conversion of all Series F Preferred Stock the Company shall not reduce
the number of shares  required to be reserved for issuance under this Section 11
without the written consent of all Holders except for a reduction  proportionate
to a reverse stock split  effected for a business  purpose other than  affecting
the  obligations  of Holder  under this Section 11,  which  reverse  stock split
affects  all  shares  of  Class  A  Common  Stock  equally.  Following  complete
conversion  of all the Series F Preferred  Stock,  the Company may, with fifteen

                                       11

(15) days prior  written  notice to Holder,  reduce the  Reserved  Amount to one
hundred  twenty-five  percent  (125%) of the  number of shares of Class A Common
Stock issuable upon the full exercise of the Common Warrants; provided, however,
that the Reserved  Amount shall  continue to be subject to increase  pursuant to
Section 11 hereof.

          (d)  ALLOCATION  OF RESERVED  AMOUNT.  Each  increase to the  Reserved
Amount  shall be  allocated  pro rata among the  Holders  based on the number of
Series F Preferred Stock, and Common Warrants held by each Holder at the time of
the  establishment of or increase in the Reserved Amount.  In the event a Holder
shall sell or otherwise  transfer any of such Holder's Series F Preferred Stock,
or Common  Warrants,  each  transferee  shall be allocated a pro rata portion of
such  transferor's  Reserved  Amount.  Any portion of the Reserved  Amount which
remains  allocated  to any  person or entity  which  does not hold any  Series F
Preferred Stock shall be allocated to the remaining  Holders,  pro rata based on
the number of Series F Preferred  Stock,  and Common  Warrants then held by such
Holders.

          (e) CAP AMOUNT.  Unless  otherwise  permitted  by Nasdaq,  in no event
shall the total number of shares of Common Stock issued upon  exercise of all of
the  Warrants  and upon  conversion  of the Series F Preferred  Stock exceed the
maximum  number of shares of Common  Stock (the "Cap  Amount")  that the Company
can,   without   shareholder   approval,   so  issue  pursuant  to  Nasdaq  Rule
4460(i)(1)(d)(ii)  (or any other applicable  Nasdaq Rules or any successor rule)
(the  "Nasdaq  20% Rule").  The Cap Amount  shall be  allocated  pro-rata to the
holders of Series F Preferred  Stock as provided in subsection (f) below. In the
event the Company is prohibited  from issuing shares of Common Stock as a result
of the  operation  of  this  subsection  (e),  the  Company  shall  comply  with
subsection (g) below.

          (f)  ALLOCATIONS  OF CAP AMOUNT AND RESERVED  AMOUNT.  The initial Cap
Amount and  Reserved  Amount  shall be  allocated  pro rata among the Holders of
Series F Preferred Stock based on the number of the shares of Series F Preferred
Stock  initially  issued to each  Holder.  Each  increase  to the Cap Amount and
Reserved  Amount  shall be  allocated  pro rata  among the  Holders  of Series F
Preferred  Stock based on the number of the shares of Series F  Preferred  Stock
held by each  Holder at the time of the  increase  in the Cap Amount or Reserved
Amount,  as the  case may be.  In the  event a holder  shall  sell or  otherwise
transfer  any of  such  Holder's  shares  of  Series  F  Preferred  Stock,  each
transferee shall be allocated a pro rata portion of such transferor's Cap amount
and  Reserved  Amount.  Any portion of the Cap Amount or Reserved  Amount  which
remains  allocated  to any  person or entity  which  does not hold any  Series F
Preferred Stock shall be allocated to the remaining  holders of shares of Series
F Preferred  Stock, pro rata based on the number of shares of Series F Preferred
Stock then held by such Holders.

          (g) INABILITY TO CONVERT DUE TO CAP AMOUNT.

               (i)  OBLIGATION  TO CURE.  If,  on the last  business  day of any
month,  or at any time a Holder so notifies  the  Company in  writing,  the then
unissued  portion of any  Holder's Cap Amount is less than 125% of the number of
shares of Common Stock then issuable upon  conversion of such Holder's shares of
Series F Preferred Stock (a "Trading Market Trigger  Event"),  the Company shall
immediately  notify the Holders of Series F Preferred  Stock of such  occurrence
and shall  immediately  take all  necessary  action  (including,  if  necessary,
approval of its  shareholders  to  authorize  the issuance of the full number of
shares of Common Stock which would be issuable  upon the  conversion of Series F
Preferred  Stock but for the Cap Amount) to  eliminate  any  prohibitions  under
applicable law or the rules or regulations  of any stock  exchange,  interdealer

                                       12

quotation system or other  self-regulatory  organization  with jurisdiction over
the Company or any of its securities on the Company's ability to issue shares of
Common Stock in excess of the Cap Amount.

               (ii)  REMEDIES.  In the event the Company  fails to eliminate all
such prohibitions  within one hundred twenty (120) days after the Trading Market
Trigger Event  (provided,  however,  that (A) the Company must file  preliminary
proxy  materials  with the SEC within  thirty  (30) days of the  Trading  Market
Trigger Event and (B) officers and directors of the Company shall  promptly upon
the occasion of any such Trading  Market  Trigger  event enter into  irrevocable
agreements  to  vote  all  of  their  shares  in  favor  of   eliminating   such
prohibitions), each Holder of Series F Preferred Stock shall thereafter have the
option,  exercisable  in whole  or in part at any time and from  time to time by
delivery of written notice ("Cap Redemption  Notice") to the Company, to require
the Company to purchase for cash, at an amount per share to the Redemption Price
at the Company's  Election (as defined in Section 6(i) above),  a portion of the
Holder's  Series F  Preferred  Stock  such  that,  after  giving  effect to such
purchase,  the holder's  allocated portion of the Cap Amount exceeds 125% of the
total number of shares of Common Stock  issuable to such holder upon  conversion
of its Series F Preferred Stock on the date of such Cap Redemption Notice.

     Section 12. FAILURE TO SATISFY CONVERSIONS.

          (a) CONVERSION FAILURE PAYMENTS. If, at any time, (x) a Holder submits
a Notice of Conversion  (or is deemed to submit such notice  pursuant to Section
5(d) hereof),  and the Company  fails for any reason to deliver,  on or prior to
the expiration of the Deadline  ("Delivery  Period") for such  conversion,  such
number of  shares of Class A Common  Stock to which  such  Converting  Holder is
entitled upon such  conversion,  or (y) the Company provides notice to Holder at
any time of its  intention  not to issue  shares  of Class A Common  Stock  upon
exercise by Holder of its conversion rights in accordance with the terms of this
Certificate of Designation  (each of (x) and (y) being a "Conversion  Failure"),
then the  Company  shall pay to such  Holder  damages in an amount  equal to the
lower of:

               (i) "Damages Amount" X "D" X .005, and
               (ii) the highest  interest  rate  permitted  by  applicable  law,
where:

     "D" means the number of days beginning the date of the  Conversion  Failure
through and including the Cure Date with respect to such Conversion Failure;

     "Damages  Amount" means the Original Series F Issue Price for each share of
Series F  Preferred  Stock  subject to  conversion  plus all  accrued and unpaid
interest thereon as of the first day of the Conversion Failure.

     "Cure Date" means (i) with  respect to a  Conversion  Failure  described in
clause (x) of its definition, the date the Company effects the conversion of the
shares  of Series F  Preferred  Stock  submitted  for  conversion  and (ii) with
respect to a Conversion  Failure described in clause (y) of its definition,  the
date  the  Company  undertakes  in  writing  to issue  Class A  Common  Stock in
satisfaction  of all  conversions of Series F Preferred Stock in accordance with
the terms of this Certificate of Designation.

     The payments to which a Holder  shall be entitled  pursuant to this Section
are referred to herein as "Conversion  Failure Payments." The parties agree that
the damages  caused by a breach  hereof  would be  difficult  or  impossible  to

                                       13

estimate  accurately.  A Holder may elect to receive accrued  Conversion Failure
Payments  in cash or to convert all or any  portion of such  accrued  Conversion
Failure  Payments,  at any  time,  into  Class  A  Common  Stock  at the  lowest
Conversion  Price in  effect  during  the  period  beginning  on the date of the
Conversion  Failure  through the Cure Date for such Conversion  Failure.  In the
event a Holder  elects to receive any  Conversion  Failure  Payments in cash, it
shall so notify the  Company in  writing no later than three (3)  business  days
after the  Deadline  and  failure to so notify the  Company,  shall  entitle the
Company,  in its  sole  discretion,  to elect to make  such  Conversion  Failure
Payments in cash,  Class A Common Stock or some  combination  of the two. In the
event a Holder  elects to convert all or any portion of the  Conversion  Failure
Payments,  such Holder shall indicate on a Notice of Conversion  such portion of
the  Conversion  Failure  Payments  which  such  Holder  elects to so convert in
accordance  with this  Section  12(a) and such  conversion  shall  otherwise  be
effected in accordance with provisions of Section 5.

          (b) BUY-IN CURE.  Unless a Conversion  Failure described in clause (y)
of Section 12(a) hereof has occurred  with respect to such a Holder,  if (i) the
Company  fails for any reason to deliver  during the Delivery  Period  shares of
Class A Common  Stock to a Holder  upon a  conversion  of the Series F Preferred
Stock  and (ii)  after the  applicable  Delivery  Period  with  respect  to such
conversion,  a Holder  purchases  (in an open market  transaction  or otherwise)
shares of Class A Common Stock to make  delivery  upon a sale by a Holder of the
shares of Class A Common Stock (the "Sold Shares") which such Holder anticipated
receiving upon such  conversion (a "Buy-In"),  the Company shall pay such Holder
(in addition to any other remedies  available to Holder) the amount by which (x)
such Holder's total purchase price (including brokerage commission,  if any) for
the shares of Class A Common  Stock so  purchased  exceeds (y) the net  proceeds
received by such  Holder from the sale of the Sold  Shares.  For  example,  if a
Holder purchases shares of Class A Common Stock having a total purchase price of
$11,000 to cover a Buy-In  with  respect to shares of Class A Common  Stock sold
for $10,000,  the Company will be required to pay such Holder  $1,000.  A Holder
shall provide the Company written notification indicating any amounts payable to
Holder pursuant to this Section 12.

          (c)  ADJUSTMENT  TO  CONVERSION  PRICE.  If a Holder has not  received
certificates  for all shares of Class A Common  Stock  within five (5)  business
days  following  the  expiration  of  the  Delivery  Period  with  respect  to a
conversion of any portion of any of such Holder's  Series F Preferred  Stock for
any reason,  then the Conversion Price for the affected Series F Preferred Stock
shall  thereafter  be the  lesser  of (i)  the  Fixed  Conversion  Price  on the
Conversion  Date  specified in the Notice of  Conversion  which  resulted in the
Conversion  Failure and (ii) the lowest  Conversion  Price in effect  during the
period  beginning on, and including,  such Conversion Date through and including
the Cure Date. If there shall occur a Conversion  Failure of the type  described
in clause (y) of Section 12(a),  then the Fixed Conversion Price with respect to
any conversion  thereafter shall be the lowest Conversion Price in effect at any
time during the period  beginning on, and including,  the date of the occurrence
of such  Conversion  Failure through and including the Cure Date. The Conversion
Price shall thereafter be subject to further adjustment for any events described
in Section 5(d).

     Section 13. EVENTS OF DEFAULT.

          (a) HOLDER'S  OPTION TO DEMAND  PREPAYMENT.  Upon the occurrence of an
Event of Default (as herein defined),  each Holder shall have the right to elect
at any time and from time to time prior to the cure by the Company of such Event

                                       14

of Default to have all or any portion of such Holder's then outstanding Series F
Preferred  Stock prepaid by the Company for an amount equal to the Holder Demand
Prepayment Amount (as herein defined).

               (i)  The  right  of  a  Holder  to  elect   prepayment  shall  be
exercisable  upon the  occurrence  of an Event of Default by such  Holder in its
sole discretion by delivery of a Demand Prepayment Notice (as herein defined) in
accordance with the procedures set forth in this Section 13. Notwithstanding the
exercise of such  right,  the Holder  shall be  entitled  to exercise  all other
rights and  remedies  available  under the  provisions  of this  Certificate  of
Designation and at law or in equity.

               (ii) A Holder shall effect each demand for prepayment  under this
Section 13 by giving at least two (2) business days prior to written notice (the
"Demand  Prepayment  Notice")  of the date  which such  prepayment  is to become
effective (the "Effective Date of Demand of Prepayment"), the Series F Preferred
Stock  selected for prepayment  and the Holder Demand  Prepayment  Amount to the
Company at the address and facsimile number provided in the stock records of the
Company,  which Demand  Prepayment Notice shall be deemed to have been delivered
on the business day after the date of transmission of Holder's facsimile (with a
copy sent by overnight courier to the Company) of such notice.

               (iii) The  Holder  Demand  Prepayment  Amount  shall be paid to a
Holder whose Series F Preferred  Stock are being prepaid within one (1) business
day following the Effective  Date of Demand of  Prepayment;  provided,  however,
that the  Company  shall not be  obligated  to deliver any portion of the Holder
Demand Prepayment Amount until one (1) business day following either the date on
which the Series F Preferred  Stock being prepaid are delivered to the office of
the Company or the Transfer  Agent, or the date on which the Holder notifies the
Company or the Transfer Agent that such Series F Preferred Stock have been lost,
stolen or destroyed and delivers the  documentation  required in accordance with
Section 5(b)(i) hereof.

          (b) HOLDER DEMAND  PREPAYMENT  AMOUNT.  The "Holder Demand  Prepayment
Amount"  means the  greater  of: (a) 1.3 times the Stated  Value of the Series F
Preferred  Stock for which  demand is being  made,  plus all  accrued and unpaid
interest  thereon and accrued and unpaid  Conversion  Failure  Payments (if any)
through the date of  prepayment  and (b) the product of (1) the highest price at
which the Class A Common Stock is traded on the date of the Event of Default (or
the most recent  highest  closing  bid price if the Class A Common  Stock is not
traded on such date) divided by the Conversion Price in effect as of the date of
the Event of  Default,  and (2) the sum of the Stated  Value and all accrued and
unpaid Conversion Failure Payments (if any) through the date of prepayment.

          (c)  EVENTS OF  DEFAULT.  An "Event of  Default"  means any one of the
following:

               (i) a Conversion Failure described in Section 12(a) hereof;

               (ii) a Share  Authorization  Failure  described in Section  11(b)
hereof,  if such Share  Authorization  Failure continues uncured for ninety (90)
days after the Reservation Trigger Date;

                                       15

               (iii) the Company fails, and such failure  continues  uncured for
three (3) business days after the Company has been  notified  thereof in writing
by a Holder, to satisfy the share reservation requirements of Section 11 hereof;

               (iv) the  Company  fails to maintain  an  effective  registration
