ITEM 5.   OTHER EVENTS
- -------   ------------

           On January 26,  1998,  the Company  completed a private  placement of
5,000 shares of its  newly-created  Series C  Convertible  Preferred  Stock (the
"Preferred  Shares") and Warrants to purchase an aggregate of 200,000  shares of
the  Company's  Common Stock (the  "Warrants")  to two  qualified  institutional
buyers and three other accredited  investors for an aggregate  purchase price of
$5,000,000.

           The following  discussion of the Preferred Shares and the Warrants is
qualified in its entirety by reference to the  Certificate of Designation  under
which the Preferred Shares were created (the  "Certificate of Designation")  and
to the form of Warrant  which  appear as Exhibits  4.1 and 99.1 to this  Report,
respectively.

           The Preferred Shares bear no dividends, have a liquidation preference
of $1,150 per Preferred  Share and have no voting rights,  except as required by
the Delaware General  Corporation Law and with respect to (a) any changes to the
Certificate of Designation or the Company's  Certificate of Incorporation  which
would  amend,  alter,  change  or  repeal  any  of  the  powers,   designations,
preferences  and  rights of the  Preferred  Shares and (b) any  issuance  of any
additional such Preferred  Shares.  The Preferred  Shares are  convertible  into
shares of the Company's Common Stock commencing on May 27, 1998, following which
a holder may convert, in any thirty-day period, up to one-third of the aggregate
number of Preferred  Shares  purchased by the initial  holder of such  Preferred
Shares,  subject to acceleration of such conversion  right in certain cases. The
Preferred  Shares are convertible  into shares of the Company's Common Stock (a)
at a  conversion  price  equal to  approximately  $7.08  per share  (the  "Fixed
Conversion  Price") until July 25, 1997 and (b) thereafter at a conversion price
equal to the lower of (i) the Fixed  Conversion Price or (ii) 95% (or 90% if the
Company's cash, cash equivalents and marketable securities at December 26, 1997,
adjusted to give effect to the receipt by the Company of the  proceeds  from the
sale of the  Preferred  Shares and  Warrants,  is less than $6.0 million) of the
average of the closing bid prices of the  Company's  Common Stock during the ten
consecutive  trading  days  immediately  preceding  the  conversion  date of the
Preferred Shares. The Fixed Conversion Price and percentages set forth above are
subject to reduction in the event, among other things, a registration  statement
under the Securities Act of 1933, as amended (the  "Securities  Act"),  covering
the shares of Common Stock underlying the Preferred Shares is not filed with the
Securities and Exchange  Commision by February 26, 1998 or declared effective by
May 26, 1998 or thereafter,  subject to certain  exceptions,  sales of shares of
Common  Stock   underlying  the  Preferred  Shares  cannot  be  made  under  the
registration  statement.  The conversion  price is also subject to  antidilution
adjustments under a formula in certain  circumstances,  including,  with certain
exceptions,  (a) the  issuances of Common  Stock,  or the issuance of securities
which are exercisable  into,  exchangeable for or convertible into Common Stock,
for a consideration  (including amounts receivable upon such exercise,  exchange
or conversion) at below the then Fixed  Conversion Price and (b) subdivisions or
combination of the Company's  Common Stock.  The Company is subject to potential
penalties in the event it fails to timely permit conversion of Preferred Shares.
The Company is not obligated to issue more than 1,520,000 shares of Common Stock
upon

                                       -2-

<PAGE>



conversion  of Preferred  Shares if the issuance of a larger number would breach
the Company's obligations under rules and regulations of The Nasdaq Stock Market
(the "Exchange  Cap").  If the Company cannot issue Common Stock for any reason,
including  by reason of the  Exchange  Cap, or fails to have  sufficient  shares
registered under the Securities Act for resale,  the Company is to issue as many
shares of Common Stock as it is able to issue without  violating any restriction
and the holder of unconverted Preferred Shares may, among other things,  require
the  Company to redeem  those  Preferred  Shares  which the Company is unable to
convert at a redemption price per Preferred Share equal to the greater of $1,150
or the closing bid price on the  proposed  conversion  date of the Common  Stock
which would have otherwise been issued.

           Unless converted or redeemed prior thereto,  the Preferred Shares are
to be automatically  converted into Common Stock on January 26, 2003 (subject to
possible delay in certain instances). The Company may also require conversion of
the Preferred  Shares at any time on or after  January 26, 2001,  subject to the
fulfillment of certain conditions.

           The Preferred Shares are redeemable,  prior to conversion, (a) at the
option of the  Company  until May 26, 1998 at a  redemption  price of $1,150 per
Preferred Share and (b) at the option of the holders thereof at a price equal to
the higher of $1,150 or the then closing bid price of the  underlying  shares of
the Company's Common Stock in the event of certain business  combinations of the
Company, the sale of substantially all of the Company's assets or in the case of
a purchase,  tender or exchange offer for more than 50% of the Company's  Common
Stock and in certain other cases, including the failure of the Company to obtain
effectiveness  of the  registration  statement  discussed above by September 23,
1998, to maintain such registration statement effective for specified periods of
time,  to  maintain  the  listing of the  Company's  Common  Stock on the Nasdaq
National Market or to convert Preferred Shares.

           The Warrants are  exercisable  until  January 25, 2001 at an exercise
price equal to approximately $7.03 per share, subject to adjustment in the event
of stock splits, dividends, combinations,  reclassifications,  recapitalizations
or like capital adjustments.

           The Company has also agreed to file, on or prior to March 27, 1998, a
registration  statement  under the  Securities Act covering the shares of Common
Stock  issuable  upon  conversion  of the  Preferred  Shares and exercise of the
Warrants for resale by the  investors  should they choose to do so following any
conversion of the Preferred  Shares or any exercise of the Warrants,  and to use
its best efforts to have such registration  statement declared effective as soon
as is  practicable,  but in no event  later than May 26,  1998.  The Company has
further agreed to maintain the registration statement effective until all shares
of Common Stock issued upon  conversion of the Preferred  Shares and exercise of
the Warrants are sold or until they may be sold without registration pursuant to
paragraph (k) of Rule 144 promulgated  under the Securities Act. The Company has
also agreed to permit, with certain  exceptions,  the investors to join in other
registration  statements  filed  by the  Company.  The  Company  is to bear  all
expenses  in  connection  with any such  registration  other  than  underwriting
discounts and commissions,  fees and disbursements of investment bankers for the
investors and counsel fees in excess of a specified amount.

           In  connection  with  such  private  placement,  the  Company  paid a
commission of $250,000 to a registered broker-dealer for its services in placing
the Preferred Shares and Warrants.

           The net proceeds  from the private  placement are intended to be used
to purchase  additional  equipment  and leasehold  improvements  to increase the
Company's  manufacturing  capacity to support recently awarded contracts and for
working capital.

                      SERIES C CONVERTIBLE PREFERRED STOCK

                              TII INDUSTRIES, INC.


        TII  INDUSTRIES,  INC., a corporation  organized and existing  under the
laws of the State of Delaware (the "Corporation"), DOES HEREBY CERTIFY:

        1.      The Certificate of Incorporation of the Corporation,  as amended
and restated,  authorizes the issuance of 1,000,000  shares of Preferred  Stock,
par value $1.00 per share, in one or more series as determined from time to time
by the Board of Directors of the  Corporation,  and expressly vests in the Board
of Directors of the  Corporation  the authority to designate each series and the
number of shares thereof and to fix and determine the  preferences and relative,
participating,  optional  and  other  special  rights,  and the  qualifications,
limitations and restrictions thereof.

        2.      The  Securities  Committee  of the  Board  of  Directors  of the
Corporation,  pursuant to the authority  expressly  vested in it by the Board of
Directors  of the  Corporation  pursuant  to Section  141(c)(1)  of the  General
Corporation  Law of the State of  Delaware,  on January  23,  1998  adopted  the
following  resolutions  creating a series of 5,000  shares of  Preferred  Stock,
designated, "Series C Convertible Preferred Stock" pursuant to the provisions of
Section 151 of the General Corporation Law of the State of Delaware:

        RESOLVED,  that  pursuant  to  the  authority  vested  in the  Board  of
Directors of the  Corporation  (the "Board of Directors") in accordance with the
provisions of its  Certificate  of  Incorporation,  as amended and  restated,  a
series of the Preferred  Stock of the Corporation be, and it hereby is, created,
and that the  designation  and number thereof and the  preferences and relative,
participating,  optional and other special  rights of the shares of such series,
and the qualifications, limitations and restrictions thereof are as follows:

        1.      DESIGNATION  AND AMOUNT OF THE SERIES.  The shares of the series
of Preferred  Stock created by this  resolution  shall be designated as Series C
Convertible  Preferred Stock, $1.00 par value per share (hereinafter referred to
as the "PREFERRED  SHARES"),  and the number of shares  constituting such series
shall be 5,000.  Such  number of shares may be  decreased,  at any time and from
time to time, by resolution of the Board of Directors;  PROVIDED,  HOWEVER, that
no decrease  shall reduce the number of  Preferred  Shares to a number less than
that of the Preferred Shares then outstanding.

        2.      HOLDER'S  CONVERSION OF PREFERRED  SHARES. A holder of Preferred
Shares shall have the right, at such holder's  option,  to convert the Preferred
Shares into shares of the Company's Common Stock, $0.01 par value per share (the
"COMMON STOCK"), on the following terms and conditions:



<PAGE>



                (a)     CONVERSION  RIGHT.  Subject  to the  provisions  of this
Section 2 and Sections 3, 4, 12 and 15 below,  at any time or times beginning on
and  including  the day which is one  hundred  twenty-one  (121)  days after the
Closing  Date (as  defined  below),  any  holder of  Preferred  Shares  shall be
entitled to convert  any whole  number of  Preferred  Shares into fully paid and
nonassessable  shares  (rounded up to the nearest whole share in accordance with
Section 2(h) below) of Common Stock,  at the Conversion Rate (as defined below);
provided,  however,  that in no event  shall any holder be  entitled  to convert
Preferred Shares in excess of that number of Preferred Shares which, upon giving
effect to such conversion,  would cause the aggregate number of shares of Common
Stock  beneficially owned by the holder and its affiliates to exceed 4.9% of the
outstanding  shares of the Common Stock following such conversion.  For purposes
of the  foregoing  proviso,  the  aggregate  number of  shares  of Common  Stock
beneficially  owned by the holder and its affiliates shall include the number of
shares of Common Stock  issuable upon  conversion of the Preferred  Shares which
such holder has elected to  convert,  but shall  exclude the number of shares of
Common  Stock which  would be issuable  upon (i)  conversion  of the  remaining,
nonconverted   Preferred  Shares  beneficially  owned  by  the  holder  and  its
affiliates  and (ii) exercise or conversion of the  unexercised  or  unconverted
portion of any other securities of the Company  (including,  without limitation,
any warrants) subject to a limitation on conversion or exercise analogous to the
limitation contained herein beneficially owned by the holder and its affiliates.
Except as set forth in the preceding  sentence,  for purposes of this paragraph,
beneficial ownership shall be calculated in accordance with Section 13(d) of the
Securities Exchange Act of 1934, as amended.  The holder may waive the foregoing
limitations  by written  notice to the Company  upon not less than 61 days prior
notice  (with  such  waiver  taking  effect  only  upon the  expiration  of such
sixty-one (61) day notice period).

                (b)     CONVERSION  RATE.  The number of shares of Common  Stock
issuable upon  conversion of each of the Preferred  Shares  pursuant to Sections
(2)(a) and 2(g) shall be  determined  according  to the  following  formula (the
"CONVERSION RATE"):

                                     $1,000
                               -------------------
                                Conversion Price

        For purposes of this  Certificate of  Designation,  the following  terms
shall have the following meanings:

                        (i) "CONVERSION  PRICE" means, as of any Conversion Date
(as  defined  below)  or other  date of  determination,  the  lower of the Fixed
Conversion Price and the Floating  Conversion  Price,  each in effect as of such
date and subject to  adjustment  as provided  herein;  provided,  however,  that
during the period  ending on and  including the date which is 180 days after the
Closing  Date,  the  Conversion  Price shall be the Fixed  Conversion  Price (as
defined  below),  except that this proviso shall not apply on and after the date
of the  occurrence  of a Triggering  Event (as defined in Section 3(d) below) or
the public  announcement  or  occurrence of a Major  Transaction  (as defined in
Section 3(c) below).

<PAGE>



                        (ii) "FIXED  CONVERSION  PRICE" means 125% of the Market
Price on the Closing Date subject to adjustment as provided herein;

                        (iii) "FLOATING  CONVERSION PRICE" means, as of any date
of determination,  the amount obtained by multiplying the Conversion  Percentage
in effect as of such date by either (i) 95% of the Market  Price as of such date
or  (ii) if the sum of the  Company's  cash,  cash  equivalents  and  marketable
securities  at December  26,  1997 as same will be  reflected  in the  Company's
Quarterly Report on Form 10-Q for the quarter ended December 26, 1997,  adjusted
to give  effect to receipt by the Company of the  proceeds  from the sale of the
Preferred  Shares and Warrants  accompanying  the Preferred  Shares is less than
$6.0 million, 90% of the Market Price as of such date, as applicable;

                        (iv)  "CONVERSION  PERCENTAGE"  means  100%,  subject to
adjustment as provided in Section 2(c);

                        (v) "MARKET  PRICE" means,  with respect to any security
for any date,  the average of the Closing Bid Prices (as defined below) for such
security  during the ten  consecutive  trading days  immediately  preceding such
date;

                        (vi) "CLOSING BID PRICE"  means,  for any security as of
any date,  the last closing bid price for such  security on the Nasdaq  National
Market as reported by  Bloomberg  Financial  Markets  ("BLOOMBERG"),  or, if the
Nasdaq  National  Market is not the principal  trading market for such security,
the last closing bid price of such security on the principal securities exchange
or  trading  market  where  such  security  is listed or traded as  reported  by
Bloomberg,  or if the foregoing do not apply, the last closing bid price of such
security in the over-the-counter  market on the Nasdaq electronic bulletin board
for such  security  as  reported  by  Bloomberg,  or, if no closing bid price is
reported for such  security by  Bloomberg,  the last closing trade price of such
security  as  reported  by  Bloomberg,  or, if no last  closing  trade  price is
reported for such  security by  Bloomberg,  the average of the bid prices of any
market makers for such security as reported in the "pink sheets" by the National
Quotation  Bureau,  Inc.  for such  day.  If the  Closing  Bid  Price  cannot be
calculated  for such  security on such date on any of the foregoing  bases,  the
Closing Bid Price of such  security on such date shall be the fair market  value
as mutually  determined by the Company and the holders of Preferred  Shares.  If
the  Company and the  holders of  Preferred  Shares are unable to agree upon the
fair  market  value of the Common  Stock,  then such  dispute  shall be resolved
pursuant to Section  2(f)(iii)  below with the term  "Closing  Bid Price"  being
substituted  for  the  term  "Market  Price."  (All  such  determinations  to be
appropriately  adjusted for any stock  dividend,  stock,  split or other similar
transaction during such period).

                        (vii) "CLOSING  DATE" and "ISSUANCE  DATE" mean the date
the Preferred Shares are first issued.

STATEMENT") covering the resale

                                       -3-

of the shares of Common Stock issuable upon  conversion of the Preferred  Shares
and  required to be filed by the Company  pursuant  to the  Registration  Rights
Agreement   between  the  Company  and  the  Buyers  referred  to  therein  (the
"REGISTRATION RIGHTS AGREEMENT") is not (i) filed within thirty (30) days of the
Closing Date (the  "SCHEDULED  FILING  DATE"),  (ii)  declared  effective by the
United States  Securities and Exchange  Commission  (the "SEC") on or before the
earlier  of (x) five  (5)  business  days  after  the  Securities  and  Exchange
Commission  advises  the  Company  that  it will  not  review  the  Registration
Statement  or has no further  comments  thereon and will  entertain a request to
accelerate the  effectiveness of the  Registration  Statement or (y) one hundred
twenty (120) days after the Closing Date (the "SCHEDULED  EFFECTIVE  DATE"),  or
(iii) if after the  Registration  Statement has been  declared  effective by the
SEC, sales of all the shares of Common Stock issued or issuable upon  conversion
of the  Preferred  Shares  (without  taking  into  account  any  limitations  or
restrictions  on the timing or amount of conversions of the Preferred  Shares or
sales  of  the  underlying   Common  Stock)  cannot  be  made  pursuant  to  the
Registration  Statement  (whether  because of a failure to keep the Registration
Statement  effective,  to disclose such information as is necessary for sales to
be made pursuant to the Registration Statement, to register sufficient shares of
Common Stock or otherwise,  provided  that such  inability to sell shares is not
due to the action or inaction of the Buyers),  then,  as partial  relief for the
damages to any holder by reason of any such delay in or reduction of its ability
to sell the  underlying  shares  of  Common  Stock  (which  remedy  shall not be
exclusive of any other remedies  available at law or in equity),  the Conversion
Percentage and the Fixed Conversion Price shall be adjusted as follows:

                        (A)     CONVERSION PERCENTAGE. The Conversion Percentage
in effect at such time shall be reduced by a number of  percentage  points equal
to the  product  of (I) .06 and (II) the sum of (x) the number of days after the
Scheduled  Effective  Date  until  (but  excluding)  the date that the  relevant
Registration  Statement  is declared  effective by the SEC and (y) the number of
days that  sales  cannot  be made  pursuant  to the  Registration  Statement  in
accordance  with  the  Registration  Rights  Agreement  after  the  Registration
Statement  has been  declared  effective,  without  including the number of days
during any Grace Period (as defined in the Registration  Rights Agreement) (such
number of days  being  collectively  referred  to  herein  as the  "REGISTRATION
STATEMENT DEFAULT DAYS").  (For example,  if the Registration  Statement becomes
effective  thirty (30) days after the Scheduled  Effective  Date  (regardless of
when the Registration  Statement is filed),  the Conversion  Percentage would be
98.2% percent until any subsequent adjustment;  if thereafter sales could not be
made  pursuant  to  the  Registration  Statement  for a  period  of  forty  (40)
additional days, the Conversion Percentage would then be 95.8%); and

                        (B)     FIXED  CONVERSION  PRICE.  The Fixed  Conversion
Price in effect at such time shall be reduced by an amount  equal to the product
of (I) the Fixed  Conversion  Price in effect  as of the  Closing  Date and (II)
 .0006 multiplied by (III) Registration  Statement Default Days. The Registration
Statement  Default  Days shall not  include  the number of days during any Grace
Period (as defined in the Registration Rights Agreement). (For example, assuming
for purposes of this Section 3(c)(B) only that the Fixed Conversion Price equals
$5.00, if the Registration  Statement  becomes  effective thirty (30) days after
the Scheduled  Effective Date, the Fixed  Conversion  Price would be $4.91 until
any subsequent adjustment; if thereafter sales could not be made pursuant to the

                                       -4-

<PAGE>



Registration  Statement for a period of forty (40)  additional  days,  the Fixed
Conversion Price would then be $4.79.)

                (d)     ADJUSTMENT  TO  CONVERSION  PRICE -- DILUTION  AND OTHER
EVENTS.  In  order  to  prevent  dilution  of  the  rights  granted  under  this
Certificate of Designation,  the Conversion  Price will be subject to adjustment
from  time to time as  provided  in this  Section  2(d).  No  adjustment  of the
Conversion  Price  shall be made if the  result of the  computation  would be to
adjust the  Conversion  Price by an amount less than $.02 (and any fraction of a
cent  shall be  rounded  down to the  nearest  cent)  but,  in that  event,  any
adjustment  that would  otherwise  be required  then to be made shall be carried
forward  and  shall be made at the  time of and  together  with  any  subsequent
adjustment  which,  together  with any  adjustment  or  adjustments  so  carried
forward, shall amount to $.02 or more.

                        (i) ADJUSTMENT OF FIXED  CONVERSION  PRICE UPON ISSUANCE
OF  COMMON  STOCK.  If and  whenever  on or after  the date of  issuance  of the
Preferred  Shares,  the Company issues or sells,  or is deemed to have issued or
sold as hereinafter provided, any shares of Common Stock for a consideration per
share less than the Fixed Conversion Price in effect  immediately  prior to such
time (the "APPLICABLE  PRICE"),  then immediately  after such issue or sale, the
Fixed Conversion Price shall be reduced to an amount equal to the product of (x)
the Fixed Conversion Price in effect immediately prior to such issue or sale and
(y) the  quotient  determined  by dividing (1) the sum of (I) the product of the
Applicable Price and the number of shares of Common Stock Deemed Outstanding (as
defined  below)   immediately  prior  to  such  issue  or  sale,  and  (II)  the
consideration,  if any,  received by the Company upon such issue or sale, by (2)
the product of (I) the Applicable  Price and (II) the number of shares of Common
Stock Deemed  Outstanding  immediately  after such issue or sale.  No adjustment
shall be made with  respect to shares of Common Stock deemed to have been issued
by the Company in  connection  with the  issuance  or  conversion  of  Preferred
Shares,  the issuance or exercise of the Warrants (as defined in the  Securities
Purchase  Agreement between the Company and the initial holders of the Preferred
Shares (the "SECURITIES  PURCHASE  AGREEMENT"),  the issuance of shares upon the
exercise of options,  warrants and Convertible Securities outstanding on January
23,  1998 (as set  forth in the  Securities  Purchase  Agreement),  the grant or
exercise  of  options  under an  Approved  Stock Plan (as  defined  below) or an
Excluded  Issuance (as defined below).  For purposes of determining the adjusted
Fixed  Conversion  Price under this  Section  2(d)(i),  the  following  shall be
applicable:

                        (A)     ISSUANCE OF OPTIONS. If, after January 23, 1998,
the Company in any manner  grants any rights or options to  subscribe  for or to
purchase (i) Common Stock (other than pursuant to an Approved  Stock Plan or the
Warrants) or (ii) any stock or other securities convertible into or exchangeable
for Common Stock (such rights or options being herein called  "OPTIONS" and such
convertible or exchangeable stock or securities being herein called "CONVERTIBLE
SECURITIES") and the price per share for which Common Stock is issuable upon the
exercise of such  Options or upon  conversion  or  exchange of such  Convertible
Securities is less than the Applicable  Price,  then the total maximum number of
shares of Common  Stock  issuable  upon the  exercise  of such  Options  or upon
conversion  or  exchange  of  the  total  maximum  amount  of  such  Convertible
Securities  issuable  upon the  exercise of such  Options  shall be deemed to be
outstanding

                                       -5-

<PAGE>



and to have been issued and sold by the  Company  for such price per share.  For
purposes of this Section 2(d)(i)(A), the "price per share for which Common Stock
is issuable upon exercise of such Options or upon conversion or exchange of such
Convertible  Securities" is determined by dividing (I) the total amount, if any,
received or receivable by the Company as consideration  for the granting of such
Options,  plus the minimum aggregate amount of additional  consideration payable
to the Company upon the exercise of all such  Options,  plus in the case of such
Options which relate to Convertible Securities,  the minimum aggregate amount of
additional  consideration,  if any,  payable to the Company upon the issuance or
sale of such Convertible  Securities and the conversion or exchange thereof,  by
(II) the total maximum  number of shares of Common Stock  issuable upon exercise
of such  Options or upon the  conversion  or  exchange  of all such  Convertible
Securities  issuable  upon the exercise of such  Options.  No  adjustment of the
Fixed  Conversion  Price  shall be made upon the actual  issuance of such Common
Stock or of such  Convertible  Securities  upon the  exercise of such Options or
upon the actual  issuance of such Common  Stock upon  conversion  or exchange of
such Convertible Securities.

                        (B)     ISSUANCE  OF  CONVERTIBLE  SECURITIES.   If  the
Company in any manner issues or sells any  Convertible  Securities and the price
per share for which Common Stock is issuable upon such conversion or exchange is
less than the  Applicable  Price,  then the  maximum  number of shares of Common
Stock issuable upon conversion or exchange of such Convertible  Securities shall
be deemed to be outstanding  and to have been issued and sold by the Company for
the price per share for which Common Stock is issuable  upon such  conversion or
exchange. For the purposes of this Section 2(d)(i)(B),  the "price per share for
which Common Stock is issuable  upon such  conversion or exchange" is determined
by  dividing  (I) the total  amount  received  or  receivable  by the Company as
consideration  for the issue or sale of such  Convertible  Securities,  plus the
minimum  aggregate  amount of additional  consideration,  if any, payable to the
Company  upon the  conversion  or exchange  thereof,  by (II) the total  maximum
number of shares of Common Stock issuable upon the conversion or exchange of all
such Convertible  Securities.  No adjustment of the Fixed Conversion Price shall
be made upon the actual issue of such Common Stock upon  conversion  or exchange
of  such  Convertible  Securities  and,  if any  such  issue  or  sale  of  such
Convertible Securities is made upon exercise of any Options for which adjustment
of the  Fixed  Conversion  Price  had been or are to be made  pursuant  to other
provisions  of  this  Section  2(d)(i),  no  further  adjustment  of  the  Fixed
Conversion Price shall be made by reason of such issue or sale.

                        (C)     CHANGE IN OPTION PRICE OR RATE OF CONVERSION. If
the purchase price provided for in any Options, the additional consideration, if
any,  payable  upon  the  issue,  conversion  or  exchange  of  any  Convertible
Securities, or the rate at which any Convertible Securities are convertible into
or exchangeable  for Common Stock change at any time, the Fixed Conversion Price
in effect at the time of such change shall be readjusted to the Fixed Conversion
Price  which  would  have  been in  effect  at such  time  had such  Options  or
Convertible  Securities  still  outstanding  provided for such changed  purchase
price, additional  consideration or changed conversion rate, as the case may be,
at the  time  initially  granted,  issued  or  sold.  Nothing  in  this  Section
2(d)(i)(C)  shall  be  construed  to  require  any  readjustment  to  the  Fixed
Conversion Price where the Board of Directors of the Company votes to reprice at
fair market value any rights or options to subscribe for or to purchase

                                       -6-

Common  Stock  granted  pursuant to an  Approved  Stock Plan in order to provide
appropriate employee incentives.

                        (D)     CERTAIN DEFINITIONS. For purposes of determining
the adjusted Fixed Conversion  Price under this Section  2(d)(i),  the following
terms shall have the meanings set forth below:

                                (I)     "APPROVED  STOCK  PLAN"  shall  mean any
contract, plan or agreement which has been, or may in the future be, approved by
the  Board  of  Directors  of the  Company,  pursuant  to  which  the  Company's
securities may be issued to any employee, officer, director, consultant or other
service provider.

                                (II)    "COMMON STOCK DEEMED OUTSTANDING" means,
at any given time, the number of shares of Common Stock actually  outstanding at
such time, plus the number of shares of Common Stock deemed to be outstanding at
such given time pursuant to Sections 2(d)(i)(A) and 2(d)(i)(B) hereof regardless
of whether the Options or  Convertible  Securities  are actually  exercisable at
such time, but excluding any shares of Common Stock issuable upon  conversion of
the Preferred Shares.

                                (III)   "EXCLUDED  ISSUANCE"  shall mean (i) any
underwritten  public offering by the Company  consisting solely of Common Stock,
with or without  warrants and other rights to purchase  Common Stock,  including
Convertible  Securities (and warrants issued to the underwriter therefor as part
of the underwriters' compensation), (ii) any transaction involving the Company's
issuance of  securities in connection  with any strategic  partnership  or joint
venture (the primary purpose of which is not to raise equity capital), (iii) any
issuance of securities by a subsidiary of the Company,  and (iv) any issuance of
securities by the Company as consideration for the acquisition of a license or a
business by the Company;  provided that (x) in each  instance  under clause (ii)
immediately above the consideration  received by the Company for each such share
of Common  Stock issued is not less than the lesser of (A) the Closing Bid Price
as of the date on which the Company's Board of Directors authorizes the issuance
of such  shares  and (B) the  average of the  Closing  Bid Prices for the Common
Stock for the twenty (20)  consecutive  trading days  immediately  preceding the
date on which the Company's  Board of Directors  authorizes the issuance of such
shares,  and (y) in each  instance  under  clause  (ii) above the  consideration
received by the Company for each such share of Common Stock issued (exclusive of
underwriting  discounts,  commissions  and expense  allowances  and exclusive of
expenses  of the  Company)  is not less than 95% of the Closing Bid Price on the
date on which the Company  and the  underwriter  agree upon the public  offering
price for such shares.

                        (E)     EFFECT  ON FIXED  CONVERSION  PRICE  OF  CERTAIN
EVENTS.  For purposes of determining the adjusted Fixed  Conversion  Price under
this Section 2(d)(i), the following shall be applicable:


                                               -7-

<PAGE>



                                (I)     CALCULATION OF  CONSIDERATION  RECEIVED.
If any Common Stock,  Options or  Convertible  Securities  are issued or sold or
deemed to have been issued or sold for cash, the consideration received therefor
will be deemed to be the net amount  received by the Company  therefor.  In case
any Common Stock,  Options or  Convertible  Securities  are issued or sold for a
consideration  other than cash, the amount of the consideration  other than cash
received by the  Company  will be the fair value of such  consideration,  except
where such  consideration  consists of  securities,  in which case the amount of
consideration  received by the  Company  will be the  arithmetic  average of the
Closing Bid Prices of such  securities  on the twenty (20)  consecutive  trading
days  immediately  preceding  the  date  of  receipt.  The  fair  value  of  any
consideration  other than cash or securities  will be determined  jointly by the
Company and the holders of a majority of the Preferred Shares then  outstanding.
If such  parties  are unable to reach  agreement  within ten (10) days after the
occurrence of an event  requiring  valuation (the "VALUATION  EVENT"),  the fair
value of such  consideration will be determined within forty-eight (48) hours of
the tenth (10th) day following the Valuation Event by an independent,  reputable
appraiser selected by the Company.  The determination of such appraiser shall be
deemed binding upon all parties absent manifest error.

                              (II) INTEGRATED  TRANSACTIONS.  In case any Option
is issued in
connection with the issue or sale of other  securities of the Company,  together
comprising one  integrated  transaction  in which no specific  consideration  is
allocated to such Options by the parties thereto,  the Options will be deemed to
have been issued for a consideration  equal to the difference  between the total
consideration received by the Company and the consideration (calculated pursuant
to the  foregoing  clause  (I))  deemed  received  by the Company for such other
securities.

                                (III)   TREASURY SHARES. The number of shares of
Common  Stock  outstanding  at any given time shall not include  shares owned or
held by or for the account of the Company,  but the disposition of any shares so
owned or held will be considered an issue or sale of Common Stock.

                                (IV)    RECORD  DATE.  If the Company  issues to
holders of Common Stock rights entitling them (1) to receive a dividend or other
distribution payable in Common Stock,  Options or Convertible  Securities or (2)
rights to  subscribe  for or  purchase  Common  Stock,  Options  or  Convertible
Securities,  then such record date will be deemed to be the date of the issue or
sale of the shares of Common Stock or any other  securities  deemed to have been
issued or sold upon the declaration of such dividend or the making of such other
distribution  or the  date of the  granting  of such  right of  subscription  or
purchase, as the case may be.

                (ii)    ADJUSTMENT OF FIXED CONVERSION PRICE UPON SUBDIVISION OR
COMBINATION OF COMMON STOCK. If the Company at any time subdivides (by any stock
split, stock dividend,  recapitalization or otherwise) its outstanding shares of
Common  Stock into a greater  number of shares,  the Fixed  Conversion  Price in
effect immediately prior to such subdivision will be proportionately reduced. If
the  Company  at any time  combines  (by  combination,  reverse  stock  split or
otherwise)  its  outstanding  shares of Common  Stock  into a smaller  number of
shares,  the  Fixed  Conversion  Price  in  effect  immediately  prior  to  such
combination will be proportionately increased.

                                       -8-

<PAGE>




                (iii)   ADJUSTMENT OF FLOATING CONVERSION PRICE UPON ISSUANCE OF
CONVERTIBLE SECURITIES. If the Company in any manner issues or sells Convertible
Securities that are  convertible  into Common Stock at a price which varies with
the market price of the Common Stock (the  formulation  for such variable  price
being herein  referred to as, the "VARIABLE  PRICE") and such Variable  Price is
not calculated using the same formula used to calculate the Floating  Conversion
Price in effect immediately prior to the time of such issue or sale, the Company
shall provide written notice thereof via facsimile and overnight courier to each
holder of the Preferred  Shares  ("VARIABLE  NOTICE") on the date of issuance of
such Convertible Securities.  If the holders of Preferred Shares representing at
least two-thirds (2/3) of the Preferred Shares then outstanding  provide written
notice via  facsimile  and  overnight  courier  (the  "VARIABLE  PRICE  ELECTION
NOTICE") to the Company  within five (5)  business  days of receiving a Variable
Notice that such holders desire to replace the Floating Conversion Price then in
effect with the Variable Price  described in such Variable  Notice,  the Company
shall prepare and deliver to each holder of the  Preferred  Shares via facsimile
and overnight  courier a copy of an amendment to this Certificate of Designation
(the "VARIABLE  PRICE  AMENDMENT")  that  substitutes the Variable Price for the
Floating  Conversion Price (together with such modifications to this Certificate
of Designation as may be required to give full effect to the substitution of the
Variable Price for the Floating Conversion Price) no less than five (5) business
days nor more than ten (10) business days after receipt of the requisite  number
of Variable Price Election  Notices set forth above. The Company shall file such
Variable Price Amendment with the Secretary of State of the State of Delaware no
less than five (5)  business  days nor more than ten (10)  business  days  after
delivery of the Variable Price Amendment to the holders of the Preferred Shares;
provided  that in the event  that the  Company  receives  a notice  prior to the
filing of the  Variable  Price  Amendment  from any holder who has  delivered  a
Variable Price Election  Notice in connection with such Variable Price Amendment
that such  holder  objects  to the form of the  Variable  Price  Amendment,  the
Company  shall not file such  Variable  Price  Amendment  until such time as the
Variable Price Amendment has been revised to the reasonable satisfaction of such
holder  and  approved  in  writing  by  the  holders  of  the  Preferred  Shares
representing at least two-thirds (2/3) of the Preferred Shares then outstanding.
Except as provided in the preceding  proviso,  a holder's delivery of a Variable
Price  Election  Notice  shall  serve as the  consent  required  to  amend  this
Certificate of Designation pursuant to Section 12 below. If the Company does not
receive the requisite number of Variable Price Election Notices within seven (7)
business  days after it has given  Variable  Notices to all holders of Preferred
Shares,  the holders of Preferred  Shares shall be deemed to have elected not to
replace the Floating Conversion Price then in effect.

                (iv)    REORGANIZATION, RECLASSIFICATION,  CONSOLIDATION, MERGER
OR SALE. Any recapitalization,  reorganization, reclassification, consolidation,
merger,  sale of all or  substantially  all of the  Company's  assets to another
Person (as defined below) or other  transaction  which is effected in such a way
that holders of Common Stock are  entitled to receive  (either  directly or upon
subsequent  liquidation)  stock,  securities  or assets  with  respect  to or in
exchange for Common Stock is referred to herein as an "ORGANIC CHANGE." Prior to
the  consummation  of any  Organic  Change,  the Company  will make  appropriate
provision (in form and  substance  reasonably  satisfactory  to the holders of a
majority of the Preferred Shares then outstanding) to insure that each of the

                                       -9-

<PAGE>



holders of the Preferred  Shares will  thereafter  have the right to acquire and
receive  in lieu of or  addition  to (as the case may be) the  shares  of Common
Stock  acquirable and receivable upon the conversion of such holder's  Preferred
Shares  immediately  prior  to  such  Organic  Change,  such  shares  of  stock,
securities  or assets as may be issued or payable with respect to or in exchange
for the number of shares of Common Stock immediately  theretofore acquirable and
receivable  upon the  conversion  of such  holder's  Preferred  Shares  had such
Organic Change not taken place (without  taking into account any  limitations or
restrictions  on the timing or amount of  conversions).  In any such  case,  the
Company will make appropriate  provision (in form and substance  satisfactory to
the holders of a majority of the Preferred Shares then outstanding) with respect
to such  holders'  rights and  interests to insure that the  provisions  of this
Section 2(d) and Section 2(e) below will thereafter be applicable, as closely as
practicable,  to the  Preferred  Shares  (including,  in the  case  of any  such
consolidation, merger or sale in which the successor entity or purchasing entity
is other than the Company, an immediate adjustment of the Fixed Conversion Price
to the value for the Common Stock reflected by the terms of such  consolidation,
merger or sale,  if the  value so  reflected  is less than the Fixed  Conversion
Price in effect  immediately prior to such  consolidation,  merger or sale). The
Company will not effect any such consolidation,  merger or sale, unless prior to
the  consummation  thereof,  the  successor  entity (if other than the  Company)
resulting  from  consolidation  or merger or the entity  purchasing  such assets
assumes,  by written  instrument,  the  obligation  to deliver to each holder of
Preferred  Shares such shares of stock,  securities  or assets as, in accordance
with the foregoing provisions,  such holder may be entitled to acquire. "PERSON"
shall mean an individual,  a limited liability company,  a partnership,  a joint
venture, a corporation, a trust, an unincorporated organization and a government
or any department or agency thereof.

                (v)     CERTAIN  EVENTS.   If  any  event  occurs  of  the  type
contemplated  by the provisions of this Section 2(d) but not expressly  provided
for by such provisions  (including,  without  limitation,  the granting of stock
appreciation  rights,  phantom stock rights or other rights with equity features
other than rights to be settled  exclusively in cash),  then the Company's Board
of Directors will make an appropriate  adjustment in the Conversion  Price so as
to protect the rights of the holders of the Preferred  Shares;  provided that no
such  adjustment  will  increase the  Conversion  Price as otherwise  determined
pursuant to this Section 2(d).

                                      -10-

<PAGE>





                (vi)    NOTICES.

                (A)  As  soon  as  practicable,   upon  any  adjustment  of  the
Conversion Price, the Company will give written notice thereof to each holder of
Preferred  Shares,  setting  forth  in  reasonable  detail  and  certifying  the
calculation of such adjustment.

                (B) The  Company  will give  written  notice  to each  holder of
Preferred  Shares at least ten (10) business days prior to the date on which the
Company  closes its books or takes a record (I) with  respect to any dividend or
distribution  upon  the  Common  Stock,  (II)  with  respect  to  any  pro  rata
subscription offer to holders of Common Stock or (III) for determining rights to
vote with respect to any Organic Change,  dissolution or liquidation,  but in no
event shall such notice be  provided  to such holder  prior to such  information
being made known to the public.

                (C) The Company will also give written  notice to each holder of
Preferred  Shares at least ten (10) business days prior to the date on which any
Organic Change, dissolution or liquidation will take place and in no event shall
such  notice be provided to such  holder  prior to such  information  being made
known to the public.

        (e)     PURCHASE   RIGHTS.   In  addition  to  any  adjustments  of  the
Conversion  Price  pursuant to Section  2(d)  above,  if at any time the Company
grants,  issues  or sells  any  Options,  Convertible  Securities  or  rights to
purchase  stock,  warrants,  securities or other property pro rata to the record
holders  of any class of Common  Stock  (the  "PURCHASE  RIGHTS"),  then (i) the
holders  of  Preferred  Shares  will be  entitled  to  acquire,  upon the  terms
applicable to such Purchase  Rights,  the aggregate  Purchase  Rights which such
holder  could  have  acquired  if such  holder  had held the number of shares of
Common  Stock  acquirable  upon  complete  conversion  of the  Preferred  Shares
(without  taking into account any  limitations or  restrictions on the timing or
amount of  conversions)  immediately  before the date on which a record is taken
for the grant,  issuance or sale of such Purchase Rights,  or, if no such record
is taken,  the date as of which the  record  holders  of Common  Stock are to be
determined  for the  grant,  issue or sale of such  Purchase  Rights and (ii) no
adjustment shall be made to the Fixed Conversion Price pursuant to Section 2(d).

        (f)     MECHANICS OF CONVERSION.  Subject to the Company's  inability to
fully satisfy its  obligations  under a Conversion  Notice (as defined below) as
provided for in Section 4 below:

                (i)     HOLDER'S  DELIVERY  REQUIREMENTS.  To convert  Preferred
Shares into full shares of Common Stock on any date (the "CONVERSION DATE"), the
holder  thereof  shall (A) transmit by facsimile  (or  otherwise  deliver),  for
receipt on or prior to 11:59 p.m.,  New York City Time on such date, a copy of a
fully  executed  notice of conversion  in the form attached  hereto as Exhibit I
(the "CONVERSION NOTICE"), to the Company, and (B) surrender to a common carrier
for  delivery to the Company or its  designated  transfer  agent (the  "TRANSFER
AGENT") as soon as practicable  following  such date, the original  certificates
representing the Preferred Shares being

                                      -11-

<PAGE>



converted (or an indemnification  undertaking with respect to such shares in the
case of their loss, theft or destruction)  (the "PREFERRED STOCK  CERTIFICATES")
and the originally executed Conversion Notice.

                (ii)    COMPANY'S  RESPONSE.  Upon  receipt by the  Company of a
facsimile copy of a Conversion  Notice, the Company shall promptly (but no later
than the next business day following  the date of receipt)  send,  via facsimile
(provided such holder has filed a facsimile  address with the Company,  included
in such  Conversion  Notice;  otherwise in  accordance  with the  provisions  of
Section 17 herein),  a confirmation of receipt of such Conversion Notice to such
holder. Upon receipt by the Company or the Transfer Agent of the Preferred Stock
Certificates to be converted pursuant to a Conversion Notice,  together with the
originally  executed  Conversion  Notice,  the Company or the Transfer Agent (as
applicable)  shall, on the next business day following the date of receipt,  (I)
issue and surrender to a common carrier for overnight delivery to the address as
specified in the Conversion Notice, a certificate, registered in the name of the
holder or its  designee  for the  number of shares of Common  Stock to which the
holder  shall be  entitled,  or (II) credit such  aggregate  number of shares of
Common  Stock to which the  holder  shall be  entitled  to the  holder's  or its
designee's  balance account with The Depository  Trust Company (if so designated
by the  holder in the  Conversion  Notice).  If the number of  Preferred  Shares
represented by the Preferred  Stock  Certificate(s)  submitted for conversion is
greater than the number of Preferred Shares being converted, then the Company or
Transfer  Agent,  as the case may be, shall,  as soon as  practicable  and in no
event later than two (2)  business  days after  receipt of the  Preferred  Stock
Certificate(s)  and at its own  expense,  issue and  deliver to the holder a new
Preferred  Stock  Certificate  representing  the number of Preferred  Shares not
converted.

                (iii)   DISPUTE  RESOLUTION.  In the case of a dispute as to the
determination  of  the  Market  Price  or  the  arithmetic  calculation  of  the
Conversion  Rate,  the Company shall  promptly issue to the holder the number of
shares of Common  Stock  that is not  disputed  and shall  submit  the  disputed
determinations or arithmetic calculations to the holder via facsimile as soon as
possible, but in no event later than two (2) business days after receipt of such
holder's  Conversion  Notice. If such holder and the Company are unable to agree
upon the  determination  of the Market Price or  arithmetic  calculation  of the
Conversion  Rate within one (1) business day of such disputed  determination  or
arithmetic  calculation  being  submitted to the holder,  then the Company shall
within one (1) business day submit via facsimile (A) the disputed  determination
of the Market  Price to an  independent,  reputable  investment  bank or (B) the
disputed  arithmetic  calculation  of the  Conversion  Rate to its  independent,
outside  accountant.  The  Company  shall  cause  the  investment  bank  or  the
accountant,  as the case may be, to perform the  determinations  or calculations
and notify the Company  and the holder of the results no later than  forty-eight
(48)  hours  from  the  time  it  receives   the  disputed   determinations   or
calculations.   Such  investment   bank's  or  accountant's   determination   or
calculation,  as the  case may be,  shall be  binding  upon all  parties  absent
manifest error.

                (iv)    RECORD HOLDER. The person or persons entitled to receive
the shares of Common Stock issuable upon a conversion of Preferred  Shares shall
be treated for all  purposes  as the record  holder or holders of such shares of
Common Stock on the Conversion Date.

                (v)     COMPANY'S FAILURE TO TIMELY CONVERT.  If within ten (10)
business days of the Company's or the Transfer  Agent's receipt of the Preferred
Stock Certificates to be converted and the originally executed Conversion Notice
the Company shall fail to issue a certificate to a holder or credit the holder's
balance  account with The  Depository  Trust Company for the number of shares of
Common Stock to which such holder is entitled upon such  holder's  conversion of
Preferred Shares or to issue a new Preferred Stock Certificate  representing the
number of Preferred Shares to which such holder is entitled  pursuant to Section
2(f)(ii),  in addition  to all other  available  remedies  which such holder may
pursue  hereunder  and  under  the  Securities  Purchase  Agreement   (including
indemnification  pursuant to Section 8 thereof),  the Company  shall pay (on the
last day of each calendar month during which any such failure exists) additional
damages to such holder for each date on and after the tenth (10th)  business day
after the Company's  receipt of such  Conversion  Notice that such conversion is
not timely effected in an amount equal to 0.25% of the product of (A) the sum of
the number of shares of Common  Stock not issued to the holder on a timely basis
pursuant to Section  2(f)(ii)  and to which such holder is entitled  and, in the
event the  Company has failed to deliver a Preferred  Stock  Certificate  to the
holder on a timely basis pursuant to Section 2(f)(ii) and the holder thereof has
elected to convert  same,  the number of shares of Common  Stock  issuable  upon
conversion  of  the  Preferred  Shares   represented  by  such  Preferred  Stock
Certificate  which such holder has elected to convert,  as of the last  possible
date which the Company could have issued such  Preferred  Stock  Certificate  to
such holder without  violating Section 2(f)(ii) and (B) the Closing Bid Price of
the Common Stock on the last  possible  date which the Company could have issued
such Common Stock and such Preferred Stock  Certificate,  as the case may be, to
such holder without violating Section 2(f)(ii).

        (g)     MANDATORY CONVERSION. If any Preferred Shares remain outstanding
on the Mandatory  Conversion  Date (as defined  below),  then all such Preferred
Shares shall be converted as of such date in  accordance  with this Section 2 as
if the holders of such Preferred  Shares had given the Conversion  Notice on the
Mandatory  Conversion  Date.  All holders of Preferred  Shares  shall  thereupon
surrender all Preferred Stock Certificates,  duly endorsed for cancellation,  to
the Company or the Transfer Agent.  "MANDATORY  CONVERSION  DATE" means the date
which is five (5) years after the Closing Date,  plus such number of days as the
Mandatory  Conversion  Date may be  extended  pursuant  to  Section  4(k) of the
Securities  Purchase  Agreement  or  Section  3(f)  of the  Registration  Rights
Agreement.  All shares so mandatorily converted shall cease to be outstanding on
the Mandatory  Conversion  Date and shall  thereupon only be entitled to receive
the  number of  shares  of Common  Stock  issuable  upon  such  conversion  upon
submission of the applicable Preferred Stock Certificates.

        (h)     FRACTIONAL SHARES. The Company shall not issue any fraction of a
share of Common Stock upon any conversion. All shares of Common Stock (including
fractions  thereof) issuable upon conversion of more than one Preferred Share by
a holder  thereof shall be aggregated  for purposes of  determining  whether the
conversion  would  result in the  issuance  of a  fraction  of a share of Common
Stock. If, after the  aforementioned  aggregation,  the issuance would result in
the issuance of a fraction of a share of Common Stock, the Company shall pay for
such fraction of a share

                                      -13-

<PAGE>



of Common  Stock in cash based on the Market Value of such  fractional  share on
the Conversion Date.

        (i)     TAXES.  The  Company  shall pay any and all  taxes  which may be
imposed  upon it with  respect to the issuance and delivery of Common Stock upon
the conversion of the Preferred Shares.

        (j)     CONVERSION  RESTRICTIONS.  Without  the  prior  consent  of  the
Company,  a holder of Preferred  Shares  (together with such holder's  direct or
indirect  transferee)  shall not be  entitled  to convert in any thirty (30) day
period while such Preferred  Shares are convertible more than one-third (1/3) of
the  aggregate  number of  Preferred  Shares  purchased by such holder (and such
holder's  direct or indirect  transferee) on the Issuance Date.  Notwithstanding
the foregoing,  the conversion  restriction set forth in this Section 2(j) shall
not apply if an event  constituting a Major  Transaction  (as defined in Section
3(c) below) or a Triggering  Event (as defined in Section 3(d) below) shall have
occurred or been publicly announced and be continuing.

        (k)     ADJUSTMENT   OF   CONVERSION   RESTRICTIONS   UPON  ISSUANCE  OF
CONVERTIBLE SECURITIES. If the Company in any manner issues or sells Convertible
Securities  that are  convertible  into  Common  Stock  and are  subject  to (i)
restrictions  on the  amount  of  shares  that  can be  converted,  or  (ii)  no
restrictions  on the amount of shares that can be converted (the  restriction on
conversions  or  lack  thereof  being  herein  referred  to as  the  "CONVERSION
RESTRICTION"),  and such Conversion Restriction is not formulated with using the
same time periods and  percentages  used in Section 2(j), then the Company shall
provide  written  notice  thereof via facsimile  and  overnight  courier to each
holder of the Preferred Shares ("CONVERSION  RESTRICTION NOTICE") on the date of
issuance of such  Convertible  Securities.  If the holders of  Preferred  Shares
representing at least  two-thirds (2/3) of the Preferred Shares then outstanding
which remain subject to the  restrictions  in Section (j) provide written notice
via  facsimile  and  overnight  courier (the  "CONVERSION  RESTRICTION  ELECTION
NOTICE") to the Company  within five (5) business days of receiving a Conversion
Restriction   Notice  that  such  holders   desire  to  replace  the  conversion
restrictions  set  forth in  Section  2(j) then in  effect  with the  Conversion
Restriction  described in such Conversion  Restriction Notice, the Company shall
prepare and deliver to each holder of the  Preferred  Shares via  facsimile  and
overnight courier a copy of an amendment to this Certificate of Designation (the
"CONVERSION  RESTRICTION AMENDMENT") that substitutes the Conversion Restriction
for  conversion  restrictions  set forth in  Section  2(j)  (together  with such
modifications to this Certificate of Designation as may be required to give full
effect to the  substitution  of the  Conversion  Restriction  for the conversion
restrictions  set forth in Section  2(j))  within five (5)  business  days after
receipt of the requisite number of Conversion  Restriction  Election Notices set
forth above. The Company shall file such Conversion  Restriction  Amendment with
the  Secretary of State of the State of Delaware  within five (5) business  days
after  delivery of the  Conversion  Restriction  Amendment to the holders of the
Preferred Shares;  provided that in the event that the Company receives a notice
prior to the filing of the Conversion  Restriction Amendment from any holder who
has delivered a Conversion  Restriction  Election Notice in connection with such
Conversion  Restriction  Amendment  that such holder  objects to the form of the
Conversion Restriction Amendment, the Company shall not file such

                                      -14-

<PAGE>



Conversion  Restriction Amendment until such time as the Conversion  Restriction
Amendment  has been revised to the  reasonable  satisfaction  of such holder and
approved in writing by the holders of the Preferred Shares representing at least
two-thirds (2/3) of the Preferred Shares then outstanding. Except as provided in
the preceding proviso, a holder's delivery of a Conversion  Restriction Election
Notice  shall  serve as the  consent  required  to  amend  this  Certificate  of
Designations pursuant to Section 12 below.

        (l)     CONVERSION AT THE OPTION OF THE COMPANY. At any time or times on
or after the date which is three (3) years after the Issuance  Date, the Company
shall have the right, in its sole discretion,  to require that any or all of the
outstanding   Preferred  Shares  issued  on  such  Issuance  Date  be  converted
("CONVERSION AT COMPANY'S  ELECTION") at the Conversion Rate;  provided that the
Conditions to Conversion at Company's Election (as defined below) are satisfied.
The Company  shall  exercise its right to  Conversion  at Company's  Election by
providing  each  holder of such  Preferred  Shares  written  notice  ("NOTICE OF
CONVERSION  AT COMPANY'S  ELECTION") at least thirty (30) days prior to the date
selected by the Company for conversion  ("COMPANY'S  ELECTION CONVERSION DATE").
If the  Company  elects to  require  conversion  of some,  but not all,  of such
Preferred  Shares,  the Company shall convert an amount from each then holder of
such  Preferred  Shares  equal to such  holder's  pro rata amount  (based on the
number of  Preferred  Shares then held by such holder  relative to the number of
Preferred  Shares  outstanding  on Company's  Election  Conversion  Date) of all
Preferred  Shares  the  Company  is  requiring  to be  converted.  The Notice of
Conversion  at  Company's  Election  shall  indicate (x) the number of Preferred
Shares the Company has  selected  for  conversion,  (y) the  Company's  Election
Conversion  Date,  which  date shall be not less than  thirty  (30) or more than
forty (40) days after the Company's giving of such notice, and (z) each holder's
pro rata share of outstanding  Preferred  Shares.  All Preferred Shares selected
for  conversion in  accordance  with the provision of this Section 2(l) shall be
converted as of the Company's  Election  Conversion Date in accordance with this
Section 2 as if the holders of such Preferred  Shares selected by the Company to
be  converted  had  given  the  Conversion  Notice  on  the  Company's  Election
Conversion Date. All Preferred Shares so called for conversion shall cease to be
outstanding on the Company's  Election  Conversion Date and shall thereupon only
be entitled to receive the number of shares of Common Stock  issuable  upon such
conversion upon submission of the applicable  Preferred Stock Certificates.  All
holders of Preferred  Shares shall thereupon and within two (2) business days of
the  Company's   Election   Conversion   Date  surrender  all  Preferred   Stock
Certificates  selected for conversion,  duly endorsed for  cancellation,  to the
Company or the Transfer Agent.  "CONDITIONS TO CONVERSION AT COMPANY'S ELECTION"
means the following conditions: (i) unless paragraph (k) of Rule 144 promulgated
under the  Securities  Act of 1933,  as amended  ("RULE 144") is available  with
respect  to the sale of such  Conversion  Shares,  on each day during the period
beginning  twenty (20) days prior to the Notice of  Conversion  at the Company's
Election and ending on and including the Company's Election Conversion Date, the
Registration  Statement  shall be effective  and  available  for the sale of the
number of Conversion Shares then issuable upon the conversion of all outstanding
Preferred Shares,  including the Conversion Shares to be issued pursuant to such
Conversion at the  Company's  Election (up to the Exchange Cap allocable to such
Preferred  Shares  pursuant to Section  11),  (ii) on each day during the period
beginning  twenty  (20)  days  prior  to the  date of the  Company's  Notice  of
Conversion at

                                      -15-

<PAGE>



Company's Election and ending on and including the Company's Election Conversion
Date,  the Common  Stock is  designated  for  quotation  on the Nasdaq  National
Market, The New York Stock Exchange,  Inc. or The American Stock Exchange,  Inc.
and is not  suspended  from  trading;  (iii) none of the holders shall have been
subject to a lockup  agreement  under  Section 4(k) of the  Securities  Purchase
Agreement at any time during the period  beginning twenty (20) days prior to the
date of the Company's  Notice of Conversion at Company's  Election and ending on
and including the Company's  Election  Conversion  Date;  (iv) the Company shall
have timely  delivered  Conversion  Shares with  respect to such  Conversion  at
Company's Election,  and (v) the Company has otherwise satisfied its obligations
in all  material  respects  under,  and is  not  then  in  default  under,  this
Certificate of Designation,  the Securities Purchase Agreement, the Registration
Rights  Agreement  and the  Warrants  issued in  conjunction  with the  original
issuance  of the  Preferred  Shares.  Notwithstanding  the above,  any holder of
Preferred  Shares may convert such shares  (including  Preferred Shares selected
for  conversion)  into Common Stock  pursuant to Section 2(a) on or prior to the
date immediately  preceding the Company's  Election  Conversion Date (and, after
such holder's receipt of the Notice of Conversion at Company's Election, without
regard to the conversion  limitations set forth in Section 2(j) above other than
the  restrictions  contained  in  Sections  4 and 11  which  shall  continue  to
pertain).

        3.      REDEMPTION AT OPTION OF HOLDERS.

                (a)     REDEMPTION OPTION UPON MAJOR TRANSACTION. In addition to
all  other  rights  of  the  holders  of  Preferred  Shares  contained   herein,
simultaneous  with or after the  occurrence of a Major  Transaction  (as defined
below),  each holder of Preferred  Shares shall have the right, at such holder's
option,  to require  the  Company  to redeem  all or a portion of such  holder's
Preferred  Shares at a price per  Preferred  Share  equal to the  greater of (i)
$1,150 and (ii) the product of (A) the Conversion  Rate at such time and (B) the
Closing  Bid  Price  on the  date  of the  public  announcement  of  such  Major
Transaction or the next date on which the exchange or market on which the Common
Stock is traded is open if such public announcement is made (X) after 12:00 p.m.
(noon),  New York  City  Time,  time on such  date or (Y) on a date on which the
exchange  or  market  on which the  Common  Stock is  traded  is closed  ("MAJOR
TRANSACTION REDEMPTION PRICE").

                (b)     REDEMPTION  OPTION UPON TRIGGERING EVENT. In addition to
all other rights of the holders of Preferred  Shares contained  herein,  after a
Triggering Event (as defined below),  each holder of Preferred Shares shall have
the right,  at such holder's  option,  to require the Company to redeem all or a
portion of such holder's  Preferred  Shares at a price per Preferred Share equal
to the greater of (i) $1,150, and (ii) the product of (A) the Conversion Rate at
such time and (B) the Closing Bid Price  calculated as of the last date on which
the exchange or market on which the Common  Stock is traded is open  immediately
preceding  such  Triggering  Event  ("TRIGGERING  EVENT  REDEMPTION  PRICE" and,
collectively with "MAJOR TRANSACTION REDEMPTION PRICE," the "REDEMPTION PRICE").

                (c)     "MAJOR  TRANSACTION".  A  "MAJOR  TRANSACTION"  shall be
deemed to have occurred at such time as any of the following events:

                                      -16-

<PAGE>




                        (i)     the  consolidation,  merger  or  other  business
combination of the Company with or into another Person (other than pursuant to a
migratory merger effected solely for the purpose of changing the jurisdiction of
incorporation of the Company or changing the Company into a holding or operating
company);

                        (ii)    the sale or transfer of all or substantially all
of the Company's assets; or

                        (iii)   a purchase, tender or exchange offer made to and
accepted  by the  holders of more than 50% of the  outstanding  shares of Common
Stock.

                (d)     "TRIGGERING EVENT". A "TRIGGERING EVENT" shall be deemed
to have occurred at such time as any of the following events:

                        (i)     the failure of the Registration  Statement to be
declared  effective by the SEC on or prior to the date that is two hundred forty
(240) days after the Closing Date;

                        (ii)    while the Registration  Statement is required to
be  maintained  effective  pursuant  to the  terms  of the  Registration  Rights
Agreement, the effectiveness of the Registration Statement lapses for any reason
(including,  without limitation, the issuance of a stop order) or is unavailable
to the holder of the Preferred Shares for sale of the Registrable Securities (as
defined in the  Registration  Rights  Agreement) in accordance with the terms of
the Registration  Rights Agreement,  and such lapse or unavailability  continues
for a period  of ten (10)  consecutive  trading  days (in  addition  to any days
during a Grace  Period (as defined in Section  3(f) of the  Registration  Rights
Agreement)),  provided that the cause of such lapse or unavailability is not due
to factors primarily within the control of such holder of Preferred Shares;

                        (iii)   the failure of the Common  Stock to be listed on
the Nasdaq National  Market,  The New York Stock Exchange,  Inc. or The American
Stock Exchange, Inc. for a period of seven (7) consecutive days; or

                        (iv)    the Company's  notice to any holder of Preferred
Shares,  including by way of public announcement,  at any time, of its intention
not to comply with proper  requests for conversion of any Preferred  Shares into
shares of Common Stock, including due to any of the reasons set forth in Section
4(a) below.

                (e)     MECHANICS  OF  REDEMPTION  AT OPTION OF BUYER UPON MAJOR
TRANSACTION. No sooner than fifteen (15) days nor later than ten (10) days prior
to the  consummation  of a  Major  Transaction,  but  not  prior  to the  public
announcement of such Major Transaction, the Company shall deliver written notice
thereof via facsimile and overnight  courier ("NOTICE OF MAJOR  TRANSACTION") to
each holder of Preferred  Shares. At any time after receipt of a Notice of Major
Transaction,  the holders of at least  two-thirds  (2/3) of the Preferred Shares
then outstanding may

                                      -17-

<PAGE>



require  the  Company  to  redeem  all of the  holders'  Preferred  Shares  then
outstanding  by delivering  written  notice  thereof via facsimile and overnight
courier  ("NOTICE OF REDEMPTION AT OPTION OF BUYER UPON MAJOR  TRANSACTION")  to
the  Company,  which  Notice  of  Redemption  at  Option  of  Buyer  Upon  Major
Transaction  shall indicate (i) the number of Preferred Shares that such holders
are voting in favor of  redemption  and (ii) the  applicable  Major  Transaction
Redemption Price, as calculated pursuant to Section 3(a) above.

                (f)     MECHANICS  OF   REDEMPTION   AT  OPTION  OF  BUYER  UPON
TRIGGERING EVENT. Within one (1) day after the occurrence of a Triggering Event,
the Company shall  deliver  written  notice  thereof via facsimile and overnight
courier ("NOTICE OF TRIGGERING  EVENT") to each holder of Preferred  Shares.  At
any time  after  receipt  of a Notice of  Triggering  Event,  any  holder of the
Preferred  Shares then  outstanding may require the Company to redeem all or any
portion of the Preferred Shares held by such holder by delivering written notice
thereof via facsimile and overnight  courier ("NOTICE OF REDEMPTION AT OPTION OF
BUYER UPON  TRIGGERING  EVENT") to the Company,  which Notice of  Redemption  at
Option of Buyer Upon Triggering Event shall indicate (i) the number of Preferred
Shares that such holder is submitting  for  redemption  and (ii) the  applicable
Triggering Event Redemption Price, as calculated pursuant to Section 3(b) above.
Notwithstanding  the foregoing,  if (A) the Triggering Event is one described in
Section  3(d)(ii)  above,  and (B)  such  lapse  discontinues  and a  holder  of
Preferred  Shares  receives  notice  from  the  Company  that  the  lapse in the
effectiveness  of the  Registration  Statement no longer continues prior to such
holder's  delivery to the Company of the holder's Notice of Redemption at Option
of Buyer Upon Triggering  Event,  then the holder shall no longer have the right
to deliver a Notice of  Redemption at Option of Buyer Upon  Triggering  Event to
the Company with respect to such lapse and any outstanding Notices of Redemption
at Option of Buyer Upon Triggering Event shall be deemed canceled AB INITIO.

                (g)     PAYMENT OF REDEMPTION  PRICE. Upon the Company's receipt
of a Notice(s) of Redemption at Option of Buyer Upon Major  Transaction from the
holders of at least  two-thirds  (2/3) of the Preferred  Shares then outstanding
the Company shall  immediately  notify each holder by facsimile of the Company's
receipt of such  requisite  notice(s)  necessary to effect a redemption and each
holder  of  Preferred  Shares  shall  thereafter  promptly  send  such  holder's
Preferred  Stock  Certificates  to be redeemed  to the  Company or its  Transfer
Agent.  Upon the  Company's  receipt of a Notice(s) of  Redemption  at Option of
Buyer Upon  Triggering  Event from any holder of Preferred  Shares,  the Company
shall  immediately  notify each holder of  Preferred  Shares by facsimile of the
Company's  receipt  of such  Notice(s)  of  Redemption  at Option of Buyer  Upon
Triggering  Event and each holder  which has sent such a notice  shall  promptly
submit to the  Company or its  Transfer  Agent  such  holder's  Preferred  Stock
Certificates  which such holder has elected to have redeemed.  The Company shall
deliver the applicable  Redemption Price to such holder within ten (10) business
days after the Company's  receipt of the requisite  notices required to effect a
redemption;  provided that a holder's  Preferred Stock  Certificates  shall have
been so delivered to the Company or its Transfer Agent; provided further that if
the Company is unable to redeem all of the Preferred Shares to be redeemed,  the
Company  shall  redeem an amount  from each  holder of  Preferred  Shares  being
redeemed  equal  to such  holder's  pro-rata  amount  (based  on the  number  of
Preferred Shares held by

                                      -18-

<PAGE>



such  holder  relative to the number of  Preferred  Shares  outstanding)  of all
Preferred Shares being redeemed.  If the Company shall fail to redeem all of the
Preferred Shares  submitted for redemption  (other than pursuant to a dispute as
to the  arithmetic  calculation  of the  Redemption  Price),  in addition to any
remedy  such  holder of  Preferred  Shares may have under  this  Certificate  of
Designation and the Securities  Purchase  Agreement,  the applicable  Redemption
Price payable in respect of such unredeemed Preferred Shares shall bear interest
at the rate of 2.0% per month  (prorated for partial months) until paid in full.
Until the Company  pays such  unpaid  applicable  Redemption  Price in full to a
holder of Preferred Shares submitted for redemption,  such holder shall have the
option, in the case of a Notice of Redemption at Option of Buyer Upon Triggering
Event, and, in the event of a Notice of Redemption at Option of Buyer Upon Major
Transaction,  the holders of at least  two-thirds  (2/3) of the Preferred Shares
then outstanding  (including  Preferred Shares submitted for redemption pursuant
to this  Section 3 and for which the  applicable  Redemption  Price has not been
paid) shall have the option (the "VOID OPTIONAL  REDEMPTION OPTION") to, in lieu
of redemption,  require the Company to promptly  return to such holder(s) all of
the Preferred  Shares that were submitted for redemption by such holder(s) under
this Section 3 and for which the applicable  Redemption Price has not been paid,
by sending  written  notice  thereof to the  Company  via  facsimile  (the "VOID
OPTIONAL REDEMPTION  NOTICE").  Upon the Company's receipt of such Void Optional
Redemption  Notice(s)  and prior to  payment of the full  applicable  Redemption
Price to such holder,  (i) the  Notice(s) of  Redemption at Option of Buyer Upon
Triggering  Event or the  Notice(s) of  Redemption at Option of Buyer Upon Major
Transaction,  as the case may be,  shall be null and void with  respect to those
Preferred   Shares  submitted  for  redemption  and  for  which  the  applicable
Redemption  Price has not been paid, (ii) the Company shall  immediately  return
any  Preferred  Shares  submitted  to the Company by each holder for  redemption
under this Section 3(g) and for which the  applicable  Redemption  Price has not
been  paid,  and (iii) the Fixed  Conversion  Price of such  returned  Preferred
Shares shall be adjusted to the lesser of (A) the Fixed  Conversion  Price as in
effect on the date on which the Void Optional Redemption  Notice(s) is delivered
to the Company and (B) the lowest Closing Bid Price during the period  beginning
on the date on which the  Notice(s) of  Redemption of Option of Buyer Upon Major
Transaction  or the Notice(s) of  Redemption at Option of Buyer Upon  Triggering
Event, as the case may be, is delivered to the Company and ending on the date on
which the Void  Optional  Redemption  Notice(s)  is  delivered  to the  Company;
provided that no adjustment  shall be made if such adjustment would result in an
increase  of the Fixed  Conversion  Price  then in effect.  Notwithstanding  the
foregoing,  in the event of a dispute as to the determination of the Closing Bid
Price or the arithmetic  calculation of the Redemption Price, such dispute shall
be  resolved  pursuant to Section  2(f)(iii)  above with the term  "Closing  Bid
Price"  being  substituted  for the term  "Average  Market  Price"  and the term
"Redemption  Price" being substituted for the term "Conversion  Rate".  Payments
provided  for in this  Section  3 shall  have  priority  to  payments  to  other
stockholders in connection with a Major Transaction.

        4.      INABILITY TO FULLY CONVERT.

                (a)     HOLDER'S  OPTION IF COMPANY  CANNOT FULLY  CONVERT.  If,
upon the  Company's  receipt of a Conversion  Notice,  the Company can not issue
shares of Common Stock  registered for resale under the  Registration  Statement
for any reason, including, without limitation, because the

                                      -19-

<PAGE>



Company  (x) does  not have a  sufficient  number  of  shares  of  Common  Stock
authorized  and available,  (y) is otherwise  prohibited by applicable law or by
the rules or regulations of any stock exchange,  interdealer quotation system or
other  self-regulatory  organization  with  jurisdiction over the Company or its
Securities,  including  without  limitation  by reason of the  Exchange  Cap (as
defined in Section 11 below),  from  issuing all of the Common Stock which is to
be issued to a holder of Preferred Shares pursuant to a Conversion Notice or (z)
unless  paragraph (k) of Rule 144 is available  with respect to such  Conversion
Shares,  fails to have a sufficient  number of shares of Common Stock registered
for resale under the  Registration  Statement,  then the Company  shall issue as
many  shares  of  Common  Stock as it is able to issue in  accordance  with such
holder's  Conversion Notice and pursuant to Section 2(f) above without violating
any of the foregoing and, with respect to the unconverted  Preferred Shares, the
holder, solely at such holder's option, can elect to:

                        (i)     require  the  Company to redeem from such holder
those Preferred  Shares for which the Company is unable to issue Common Stock in
accordance with such holder's  Conversion Notice  ("MANDATORY  REDEMPTION") at a
price per  Preferred  Share  (the  "MANDATORY  REDEMPTION  PRICE")  equal to the
Triggering Event Redemption Price as of such Conversion Date;

                        (ii)    if the  Company's  inability  to  fully  convert
Preferred  Shares is pursuant to Section  4(a)(z) above,  require the Company to
issue  restricted  shares  of Common  Stock in  accordance  with  such  holder's
Conversion Notice and pursuant to Section 2(f) above;

                        (iii)   void its  Conversion  Notice  and retain or have
returned, as the case may be, the nonconverted  Preferred Shares that were to be
converted pursuant to such holder's Conversion Notice; or

                        (iv)    if the  Company's  inability  to  fully  convert
Preferred  Shares is pursuant to the Exchange Cap  described in Section  4(a)(y)
above,  require the Company to issue shares of Common Stock in  accordance  with
such  holder's  Conversion  Notice  and  pursuant  to  Section  2(f)  above at a
Conversion Price equal to the Market Price on the Closing Date.

                (b)     MECHANICS OF FULFILLING HOLDER 'S ELECTION.  The Company
shall  immediately  send via  facsimile  to a holder of Preferred  Shares,  upon
receipt of a facsimile copy of a Conversion Notice from such holder which cannot
be fully satisfied as described in Section 4(a) above, a notice of the Company's
inability to fully satisfy such holder's  Conversion  Notice (the  "INABILITY TO
FULLY CONVERT  NOTICE").  Such  Inability to Fully Convert Notice shall indicate
(i) the  reason  why the  Company  is  unable  to fully  satisfy  such  holder's
Conversion Notice, (ii) the number of Preferred Shares which cannot be converted
and (iii) the applicable Mandatory Redemption Price. Such holder must within ten
(10) business days of the  Company's  giving of such  Inability to Fully Convert
Notice deliver written notice via facsimile to the Company  ("NOTICE IN RESPONSE
TO INABILITY TO  CONVERT")  of its election  pursuant to Section 4(a) above.  If
such holder  fails to timely  deliver  such Notice in Response to  Inability  to
Convert,  such holder shall be deemed to have made the election  contemplated by
Section 4(a)(iii).

                (c)     PAYMENT OF REDEMPTION  PRICE. If such holder shall elect
to have its shares redeemed pursuant to Section 4(a)(i) above, the Company shall
pay the Mandatory  Redemption  Price in cash to such holder within ten (10) days
of the  Company's  receipt of the  holder's  Notice in Response to  Inability to
Convert.  If the Company shall fail to pay the applicable  Mandatory  Redemption
Price to such holder on a timely  basis as described in this Section 4(c) (other
than pursuant to a dispute as to the determination of the arithmetic calculation
of the  Redemption  Price),  in addition to any remedy such holder of  Preferred
Shares  may have  under  this  Certificate  of  Designation  and the  Securities
Purchase  Agreement,  such unpaid amount shall bear interest at the rate of 2.0%
per month  (prorated  for  partial  months)  until paid in full.  Until the full
Mandatory  Redemption Price is paid in full to such holder, such holder may void
the Mandatory  Redemption with respect to those  Preferred  Shares for which the
full  Mandatory  Redemption  Price  has not been  paid  and  receive  back  such
Preferred Shares. Notwithstanding the foregoing, if the Company fails to pay the
applicable  Mandatory Redemption Price within such ten (10) days time period due
to a  dispute  as to the  determination  of the  arithmetic  calculation  of the
Redemption  Rate, such dispute shall be resolved  pursuant to Section  2(f)(iii)
above  with  the  term  "Redemption   Price"  being  substituted  for  the  term
"Conversion Rate".

                (d)     PRO-RATA  CONVERSION  AND  REDEMPTION.   Conversion  and
Redemption  shall be on a "first come,  first  served"  basis.  In the event the
Company receives a Conversion  Notice, a Notice of Redemption at Option of Buyer
upon  Major  Transaction  or a Notice of  Redemption  at  Option  of Buyer  upon
Triggering  Event from more than one holder of Preferred  Shares on the same day
and the  Company  can convert  and redeem  some,  but not all, of the  Preferred
Shares  pursuant to this  Section 4, the Company  shall  convert and redeem from
each holder of Preferred  Shares electing to have Preferred Shares converted and
redeemed at such time an amount equal to such holder's pro-rata amount (based on
the number of  Preferred  Shares held by such  holder  relative to the number of
Preferred  Shares  outstanding)  of all  Preferred  Shares being  converted  and
redeemed at such time.

        5.      REISSUANCE  OF  CERTIFICATES.  In the event of a  conversion  or
redemption  pursuant to this  Certificate of Designation of less than all of the
Preferred Shares represented by a particular  Preferred Stock  Certificate,  the
Company  shall  promptly  cause to be issued and delivered to the holder of such
Preferred  Shares a  preferred  stock  certificate  representing  the  remaining
Preferred Shares which have not been so converted or redeemed.

        6.      RESERVATION OF SHARES.  The Company shall, so long as any of the
Preferred  Shares  are  outstanding,  reserve  and  keep  available  out  of its
authorized  and unissued  Common Stock,  solely for the purpose of effecting the
conversion  of the  Preferred  Shares,  such number of shares of Common Stock as
shall from time to time be  sufficient  to effect the  conversion  of all of the
Preferred Shares then outstanding;  provided that the number of shares of Common
Stock so  reserved  shall at no time be less than the lesser of (a) the  maximum
number of shares it can issue without  violating the Exchange Cap and (b)150% of
the number of shares of Common Stock for which the  Preferred  Shares are at any
time convertible;  provided further that such shares of Common Stock so reserved
shall be allocated  for issuance upon  conversion  of Preferred  Shares pro rata
among the holders of

                                      -21-

<PAGE>



Preferred  Shares  based on the number of  Preferred  Shares held by such holder
relative to the total number of authorized Preferred Shares.

        7.      VOTING RIGHTS.  Holders of Preferred Shares shall have no voting
rights,  except as  required  by law,  including  but not limited to the General
Corporation  Law of the State of  Delaware,  and as  expressly  provided in this
Certificate of Designation.

        8.      DIVIDENDS. The Preferred Shares shall not bear any dividends.

        9.      LIQUIDATION,  DISSOLUTION,  WINDING-UP.  In  the  event  of  any
voluntary or involuntary liquidation,  dissolution or winding up of the Company,
the holders of the Preferred  Shares shall be entitled to receive in cash out of
the assets of the Company,  whether from capital or from earnings  available for
distribution  to its  stockholders  (the "PREFERRED  FUNDS"),  before any amount
shall be paid to the holders of any of the  capital  stock of the Company of any
class junior in rank to the Preferred Shares in respect of the preferences as to
the distributions and payments on the liquidation, dissolution and winding up of
the  Company,  an amount per  Preferred  Share  equal to $1,150  (such sum being
referred to as the "LIQUIDATION  VALUE");  provided that, if the Preferred Funds
are  insufficient to pay the full amount due to the holders of Preferred  Shares
and  holders  of shares of other  classes  or series of  preferred  stock of the
Company  that are of equal  rank with the  Preferred  Shares as to  payments  of
Preferred Funds (the "PARI PASSU SHARES"),  then each holder of Preferred Shares
and Pari Passu Shares shall receive a percentage of the Preferred Funds equal to
the full  amount of  Preferred  Funds  payable to such  holder as a  liquidation
preference, in accordance with their respective Certificate of Designation, as a
percentage  of the full  amount of  Preferred  Funds  payable to all  holders of
Preferred  Shares and Pari Passu  Shares.  The  purchase  or  redemption  by the
Company of stock of any class,  in any manner  permitted by law,  shall not, for
the purposes hereof, be regarded as a liquidation,  dissolution or winding up of
the Company. Neither the consolidation or merger of the Company with or into any
other Person, nor the sale or transfer by the Company of less than substantially
all  of  its  assets,  shall,  for  the  purposes  hereof,  be  deemed  to  be a
liquidation,  dissolution  or winding up of the Company.  No holder of Preferred
Shares shall be entitled to receive any amounts  with  respect  thereto upon any
liquidation,  dissolution  or winding up of the  Company  other than the amounts
provided for herein.

        10.     PREFERRED  RANK.  All shares of Common  Stock shall be of junior
rank to all Preferred  Shares in respect to the preferences as to  distributions
and payments upon the  liquidation,  dissolution  and winding up of the Company.
The rights of the shares of Common Stock shall be subject to the preferences and
relative  rights of the  Preferred  Shares.  Without the prior  express  written
consent of the holders of not less than two-thirds (2/3) of the then outstanding
Preferred Shares, the Company shall not hereafter  authorize or issue additional
or other capital stock that is of senior rank to the Preferred Shares in respect
of the  preferences  as to  distributions  and  payments  upon the  liquidation,
dissolution  and winding up of the Company.  Without the prior  express  written
consent of the holders of not less than two-thirds (2/3) of the then outstanding
Preferred  Shares,  the  Company  shall  not  hereafter  authorize  or make  any
amendment to the Company's  Certificate of Incorporation or bylaws,  or file any
resolution  of the Board of Directors of the Company with the Secretary of State
of the

                                      -22-

<PAGE>



State of Delaware  containing any provisions,  which would  adversely  affect or
otherwise impair the rights or relative priority of the holders of the Preferred
Shares  relative to the holders of the Common  Stock or the holders of any other
class of  capital  stock.  In the event of the  merger or  consolidation  of the
Company with or into another  corporation,  the Preferred  Shares shall maintain
their relative powers,  designations and preferences  provided for herein and no
merger shall result inconsistent therewith.

        11.     RESTRICTION  ON REDEMPTION  AND CASH  DIVIDENDS  WITH RESPECT TO
OTHER CAPITAL  STOCK.  Until all of the Preferred  Shares have been converted or
redeemed as provided  herein,  the Company  shall not,  directly or  indirectly,
redeem, or declare or pay any cash dividend or distribution on, its Common Stock
without  the prior  express  written  consent  of the  holders  of not less than
two-thirds (2/3) of the then outstanding Preferred Shares.

        12.     LIMITATION ON NUMBER OF CONVERSION SHARES. The Company shall not
be obligated to issue upon conversion of the Preferred Shares, in the aggregate,
more than  1,520,000  shares of Common Stock (such amount to be  proportionately
and equitably  adjusted  from time to time in the event of stock  splits,  stock
dividends,  combinations,   reverse  stock  splits,  reclassification,   capital
reorganizations  and similar events relating to the Common Stock) (the "EXCHANGE
CAP") if issuance of a larger number of shares of Common Stock would  constitute
a breach of the  Company's  obligations  under the rules or  regulations  of The
Nasdaq Stock Market,  Inc. or any other principal  securities exchange or market
upon which the Common  Stock is or becomes  traded.  The  Exchange  Cap shall be
allocated  among the  Preferred  Shares  pro rata  based on the total  number of
authorized Preferred Shares.

        13.     VOTE TO CHANGE THE TERMS OF OR ISSUE PREFERRED SHARES. Except to
the extent a lesser or greater vote is  permitted or required  elsewhere in this
Certificate of Designation,  the  affirmative  vote at a meeting duly called for
such purpose,  or the written consent  without a meeting,  of the holders of not
less than two-thirds  (2/3) of the then  outstanding  Preferred  Shares shall be
required for (1) any change to this  Certificate of Designation or the Company's
Certificate of Incorporation  which would amend,  alter, change or repeal any of
the powers, designations, preferences and rights of the Preferred Shares, or (2)
any issuance of Preferred Shares other than pursuant to the Securities  Purchase
Agreement.

        14.     LOST OR STOLEN  CERTIFICATES.  Upon  receipt  by the  Company of
evidence  satisfactory  to  the  Company  of the  loss,  theft,  destruction  or
mutilation  of any  Preferred  Stock  Certificates  representing  the  Preferred
Shares,  and, in the case of loss, theft or destruction,  of any indemnification
undertaking  by the holder to the Company and, in the case of  mutilation,  upon
surrender and  cancellation of the Preferred Stock  Certificate(s),  the Company
shall execute and deliver new preferred stock  certificate(s)  of like tenor and
date;  provided,  however,  the  Company  shall  not be  obligated  to  re-issue
preferred  stock  certificates  if the  holder  contemporaneously  requests  the
Company to convert such Preferred Shares into Common Stock.

        15.     REDEMPTION AT OPTION OF THE COMPANY.

                By notice given  ("NOTICE OF REDEMPTION AT COMPANY'S  ELECTION")
at any time or times on or prior to the date which is not more than one  hundred
twenty (120) days  following the Closing Date, the Company shall have the right,
in its sole discretion, to redeem any or all of the outstanding Preferred Shares
("REDEMPTION AT COMPANY'S  OPTION") at a price per share of $1,150 (the "COMPANY
REDEMPTION PRICE"). Notice of Redemption at Company's Election shall be given by
facsimile  (to the extent the Company has been  provided a facsimile  address by
the holder of the Preferred  Shares being redeemed) and overnight  courier,  not
less than five (5) nor more than ten (10)  business days prior to the date fixed
for  redemption  (the "COMPANY  REDEMPTION  DATE"),  to each holder of record of
Preferred Shares to be redeemed; but neither the failure to give any such notice
to one or more such  holders nor any defect in any notice given shall affect the
sufficiency of the  proceedings  for  redemption as to other holders.  Each such
notice shall state the Company  Redemption  Date, the number of Preferred Shares
to be redeemed,  and, if less than all the Preferred  Shares held by such holder
are to be  redeemed,  the number of  Preferred  Shares to be redeemed  from such
holder,  the  Company  Redemption  Price  and the  place or  places  where  such
Preferred  Shares are to be  surrendered  for payment of the Company  Redemption
Price.  Notice  having  been  mailed as  aforesaid,  from and after the  Company
Redemption  Date (unless default shall be made by the Company in providing money
for the payment of the Company  Redemption  Price),  the Preferred Shares called
for redemption  shall no longer be deemed to be  outstanding,  all rights of the
holders thereof as shareholders of the Company shall cease and terminate  except
for the  right  to  receive  the  Company  Redemption  Price  and any  right  of
conversion or exchange which may be exercisable (to the extent then exercisable)
up to the close of business on the Company  Redemption  Date.  Upon surrender of
the Preferred  Stock  Certificates  evidencing  the Preferred  Shares called for
redemption in accordance with said notice, the Company shall make payment of the
Company Redemption Price with respect thereto.

after being sent by certified mail return receipt requested.

        17.     MISCELLANEOUS

                (a) RETURN TO AUTHORIZED AND UNISSUED  STATUS.  Preferred Shares
issued and reacquired or redeemed by the  Corporation,  or converted into shares
of Common  Stock  shall have the status of  authorized  and  unissued  shares of
Preferred Stock, undesignated as to series, subject to later issuance.

                (b) NO PREEMPTIVE  RIGHTS.  No holder of Preferred Shares of the
Corporation  shall,  because of his ownership of such Preferred  Shares,  have a
pre-emptive  right to purchase,  subscribe for or take any part of any shares of
capital  stock  of the  Corporation  or any  securities,  convertible  into,  or
warrants  or  options  exercisable  for,  any  shares  of  capital  stock of the
Corporation.

                              TII INDUSTRIES, INC.

                          COMMON STOCK PURCHASE WARRANT
                                                                            WP -

        1.      ISSUANCE.  For good and valuable  consideration,  the receipt of
which is hereby  acknowledged  by TII INDUSTRIES,  INC., a Delaware  corporation
(the  "Company"),   __________________________,   or  registered   assigns  (the
"Holder") is hereby granted the right to purchase at any time commencing two (2)
days  following  the date  hereof and until 5:00  P.M.,  New York City time,  on
January __, 2001 (the "Expiration Date"),  __________________________(__)  fully
paid and nonassessable  shares of the Company's Common Stock, $.01 par value per
share  (the  "Common  Stock") at an initial  exercise  price per share  equal to
$7.03125 (the "Exercise  Price"),  subject to further adjustment as set forth in
Section 6 hereof.

        2.      EXERCISE OF WARRANTS. This Warrant is exercisable in whole or in
part at the Exercise Price per share of Common Stock payable hereunder,  payable
in cash or by certified  or official  bank check,  or by "cashless  exercise" by
means of tendering  this Warrant  Certificate to the Company to receive a number
of shares of Common  Stock equal in Market Value to the  difference  between the
Market  Value of the  shares of Common  Stock  issuable  upon  exercise  of this
Warrant  and the total cash  exercise  price  thereof.  Upon  surrender  of this
Warrant  Certificate  with the annexed  Notice of Exercise  Form duly  executed,
together  with  payment of the  Exercise  Price for the  shares of Common  Stock
purchased, the Holder shall be entitled to receive a certificate or certificates
for the shares of Common Stock so purchased. For the purposes of this Section 2,
"Market Value" shall be an amount equal to the average of the closing bid prices
of a share of Common Stock for the five (5) trading days preceding the Company's
receipt of the Notice of Exercise Form duly executed.

        3.      RESERVATION  OF SHARES.  The Company  hereby  agrees that at all
times during the term of this Warrant  there shall be reserved for issuance upon
exercise of this  Warrant  such number of shares of its Common Stock as shall be
required for issuance upon exercise of this Warrant (the "Warrant Shares").  The
Company  shall use its best efforts and all due diligence to increase the number
of  shares  of  Common  Stock so  reserved  to cure any  deficiencies,  and,  if
necessary, to obtain



<PAGE>



approval  of  its  stockholders  therefor,   including   authorization  of  such
additional  number of shares of Common Stock as may be required in excess of the
number so reserved.

        4.      MUTILATION  OR LOSS OF WARRANT.  Upon  receipt by the Company of
evidence  satisfactory  to it of the loss,  theft,  destruction or mutilation of
this  Warrant,  and (in the  case of  loss,  theft or  destruction)  receipt  of
reasonably  satisfactory  indemnification,  and (in the case of mutilation) upon
surrender and cancellation of this Warrant, the Company will execute and deliver
a new  Warrant of like tenor and date and any such lost,  stolen,  destroyed  or
mutilated Warrant shall thereupon become void.

        5.      RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a stockholder in the Company, either at law or equity,
and the rights of the Holder are limited to those  expressed in this Warrant and
are not enforceable against the Company except to the extent set forth herein.

        6.      PROTECTION AGAINST DILUTION.

                6.1.    ADJUSTMENT  MECHANISM.  If an adjustment of the Exercise
Price is required  pursuant to this  Section 6, the Holder  shall be entitled to
purchase  such  number of shares  of  Common  Stock as will  cause (i) the total
number of shares of Common Stock the Holder is entitled to purchase  pursuant to
this Warrant (after such adjustment)  multiplied by the adjusted  Exercise Price
to equal (ii) the total number of shares of Common Stock the Holder was entitled
to purchase before such  adjustment  multiplied by the Exercise Price before the
adjustment.

                6.2.    CAPITAL  ADJUSTMENTS.  In case  of any  stock  split  or
combination,   stock   dividend,   reclassification   of   the   Common   Stock,
recapitalization,  or like capital adjustment  affecting the Common Stock of the
Company,  the  Exercise  Price  shall  be  proportionately  adjusted  in a fair,
equitable and  reasonable  manner so as to give effect,  as nearly as reasonably
practicable to the purposes hereof.

                6.3.    MERGER,  SALE OF ASSETS,  ETC. If at any time while this
Warrant,  or any portion hereof, is outstanding and unexpired there shall be (i)
a  reorganization  (other than a stock  split or  combination,  stock  dividend,
reclassification,  or like capital  adjustment of shares otherwise  provided for
herein),  (ii) a merger or  consolidation  of the Company  with or into  another
corporation  or other entity  including a merger or  consolidation  in which the
Company is the surviving  entity but the shares of the  Company's  capital stock
outstanding  immediately  prior to the  merger  are  converted  by virtue of the
merger  into  other  property,  whether  in the  form of  securities,  cash,  or
otherwise,  or (iii) a sale or transfer of the Company's  properties  and assets
as, or substantially as, an entirety to any other person, then as a part of such
reorganization,  merger, consolidation,  sale or transfer lawful provision shall
be made so that the holder of this  Warrant  shall  thereafter  be  entitled  to
receive upon exercise of this Warrant,  during the period  specified  herein and
payment of the Exercise  Price then in effect,  the number of shares of stock or
other  securities  or  property  resulting  from  such  reorganization,  merger,
consolidation, sale or transfer that a holder of the shares deliverable upon


                                       -2-

<PAGE>



exercise  of  this  Warrant   would  have  been  entitled  to  receive  in  such
reorganization, consolidation, merger, sale or transfer if this Warrant had been
exercised immediately before such reorganization, merger, consolidation, sale or
transfer,  all subject to further  adjustment as provided in this Section 6. The
foregoing  provisions  of this  Section 6 shall  similarly  apply to  successive
reorganization, consolidations, mergers, sales and transfers and to the stock or
securities  of any  other  corporation  or  other  entity  that  are at the time
receivable  upon the exercise of this Warrant.  If the  per-share  consideration
payable for shares in connection  with any such  transactions is in a form other
than cash or marketable  securities,  then the value of such consideration shall
be determined in good faith by the Company's Board of Directors.  In all events,
appropriate  adjustment (as  determined in good faith by the Company's  Board of
Directors)  shall be made in the  application  of the provisions of this Warrant
with respect to the rights and interests of the Holder after the transaction, to
the end that the  provisions  of this  Warrant  shall be  applicable  after that
event,  as near as  reasonably  practicable,  in relation to any shares or other
property deliverable after that event upon exercise of this Warrant.

        7.      TRANSFER TO COMPLY WITH THE SECURITIES ACT; REGISTRATION RIGHTS.

        (a)     This Warrant has not been  registered  under the  Securities Act
and has been issued to the Holder for investment purposes and not with a view to
the  distribution  of either the Warrant or the  Warrant  Shares.  Neither  this
Warrant nor any of the Warrant Shares or any other  security  issued or issuable
upon exercise of this Warrant may be sold, transferred,  pledged or hypothecated
in the absence of an effective  registration  statement under the Securities Act
relating to such security or an opinion of counsel  reasonably  satisfactory  to
the Company that  registration  is not required under the  Securities  Act. Each
certificate for the Warrant, the Warrant Shares and any other security issued or
issuable  upon  exercise  of this  Warrant  shall  contain  a legend on the face
thereof, in form and substance satisfactory to counsel for the Company,  setting
forth the restrictions on transfer contained in this Section.

        (b)     The Company agrees to file a registration statement, which shall
include  the  Warrant  Shares,  on  Form  S-3 or  another  available  form  (the
"Registration  Statement"),  pursuant  to the terms of the  Registration  Rights
Agreement between the Company and the Holder dated January 26, 1998.
