     INTRODUCTION.  SHARED  TECHNOLOGIES INC. was originally  incorporated under

Shared Technologies Inc. This restatement only restates and integrates, and does
not further amend, the provisions of the Corporation's  Restated  Certificate of
Incorporation as heretofore amended or supplemented, and there is no discrepancy
between  the   provisions   thereof  and  of  this   Restated   Certificate   of
Incorporation.  This  Restated  Certificate  of  Incorporation  was duly adopted
pursuant to Section 245 of the Delaware General  Corporation Law by the Board of
Directors.

     FIRST. The name of this corporation shall be:

                            SHARED TECHNOLOGIES INC.

     THIRD. The purpose of the corporation shall be:

     To engage in any  lawful  act or  activity  for which  corporations  may be
organized under the Delaware General Corporation Law.

     FOURTH.  The  total  number of shares  of all  classes  of stock  which the
Corporation  shall have  authority to issue is (i)  20,000,000  shares of Common
Stock, $.004 par value per share ("Common Stock"), and (ii) 10,000,000 shares of
Preferred Stock, $.01 par value per share.

     A. Common  Stock.  Shares of Common Stock shall have the  following  voting
powers, rights and preferences:

     1. Voting Rights.  Except as otherwise  required by Statute or as otherwise
provided in this Restated Certificate of Incorporation, the holders of shares of
Common  Stock shall be  entitled  to vote on all matters at all  meetings of the
stockholders  of the  Corporation,  and shall be  entitled  to one vote for each
share of Common Stock entitled to vote at such meeting,  voting together, as one
class,  with the holders of any shares of  Preferred  Stock who





are  entitled  to vote,  except to the extent that a class vote for any class or
series of stock is required by statute.

     2. Dividends.  Subject to any  preferential  dividend rights  applicable to
shares of  Preferred  Stock,  the  holders  of shares of Common  Stock  shall be
entitled to receive such dividends as may be declared by the Board of Directors.

     3. Liquidation.  In the event of any voluntary or involuntary  liquidation,
dissolution or winding up of the Corporation,  after distribution in full of the
preferential  amounts to be  distributed  to the holders of shares of  Preferred
Stock, the holders of shares of Common Stock shall be entitled to receive all of
the  remaining  assets of the  Corporation  available  for  distribution  to the
holders of Common Stock, ratably in proportion to the number of shares of Common
Stock held by them.

     B.  Preferred  Stock.  Shares of Preferred  Stock shall have the  following
voting powers, rights and preferences.

     Preferred Stock may be issued from time to time in one or more series, each
of such  series to have such  terms as stated  or  expressed  herein  and in the
resolution or resolutions  providing for the issue of such series adopted by the
Board of Directors of the Corporation as hereinafter provided. Any shares of any
series of Preferred  Stock which may be  redeemed,  purchased or acquired by the
Corporation  may be reissued as shares of the same series or as shares of one or
more other  series of  Preferred  Stock  except as  otherwise  provided  by law.
Different  series of  Preferred  Stock  shall  not be  construed  to  constitute
different  classes  of  shares  for the  purpose  of voting  by  classes  unless
expressly provided.

     Authority is hereby  expressly  granted to the Board of Directors from time
to time to issue the  Preferred  Stock in one or more series,  and in connection
with the creation of any such series, by resolution or resolutions providing for
the issue of the shares thereof,  to determine and fix such voting powers,  full
or limited, or no voting powers, and such designations, preferences and relative
participating, optional or other special rights, and qualifications, limitations
or  restrictions   thereof,   including  without  limitation   dividend  rights,
conversion rights,  redemption privileges and liquidation preferences,  as shall
be stated  and  expressed  in such  resolutions,  all to the full  extent now or
hereafter  permitted by the Delaware  General  Corporation Law. Without limiting
the generality of the foregoing,  the resolutions  providing for issuance of any
series of Preferred Stock may provide that such series shall be superior or rank
equally or be junior to the  Preferred  Stock of any other  series to the extent
permitted by law.

 
                                       2



                    DESIGNATION OF SERIES C PREFERRED STOCK

     1. Designation; Rank. The series of Preferred Stock designated and known as
"Series C Preferred Stock" shall consist of 5,000,000 shares, par value $.01 per
share.  Shares of the Series C Preferred  Stock shall,  with respect to dividend
rights and rights on liquidation,  winding up and  dissolution,  rank senior and
prior to the Common Stock, par value $.004 per share (the "Common Stock") of the
Corporation and to any other class or series of capital stock of the Corporation
hereafter issued (all of such equity  securities of the Corporation to which the
Series C Preferred Stock ranks prior, including all classes of Common Stock, are
at times collectively referred to herein as the "Junior Securities").

     2. Dividends.

     (a) The  holders of the  Series C  Preferred  Stock  shall be  entitled  to
receive,  out of any funds legally available therefor,  dividends in cash at the
annual  rate of $.32 per share  (subject  to  appropriate  adjustment  for stock
splits,  stock  dividends,   combinations  or  other  similar  recapitalizations
affecting such shares),  and no more, in equal quarterly  payments in arrears on
March 31, June 30,  September 30 and December 31 in each year (each such date is
referred to as a "Dividend  Payment  Date")  commencing  on September  30, 1992,
payable in preference and priority to any payment of any cash dividend on Common
Stock or any other shares of capital stock of this  Corporation.  Such dividends
shall be paid to the  holders  of record at the  close of  business  on the date
specified by the Board of Directors of the Corporation at the time such dividend
is declared.  If the Dividend  Payment Date is not a business  day, the Dividend
Payment Date shall be the next succeeding business day.

     (b) Each of such quarterly  dividends  shall be fully  cumulative and shall
accrue, whether or not earned or declared,  without interest, from the first day
of the quarter in which such dividend may be payable as herein provided,  except
that with respect to the first  quarterly  dividend,  such dividend shall accrue
from September 15, 1992.

     (c) No dividends  shall be declared or paid or set apart for payment on the
Junior  Securities,  or on the  Preferred  Stock of any  series  ranking,  as to
dividends,  junior to the Series C Preferred  Stock,  for any period unless full
cumulative  dividends have been or  contemporaneously  are declared and paid (or
declared  and a sum  sufficient  for the  payment  thereof  set  apart  for such
payment) on the Series C Preferred Stock for all dividend payment periods ending
on or prior to the date of payment  of



                                       3


such full cumulative dividends. Unless full cumulative dividends on the Series C
Preferred  Stock have been paid,  no other  distribution  shall be made upon the
Junior Securities or upon any other such series of Preferred Stock.

     (d) In the event that the Corporation  shall have  cumulative,  accrued and
unpaid  dividends  outstanding  immediately  prior  to,  and in the  event  of a
conversion  of any shares of Series C  Preferred  Stock as provided in Section 5
hereof,  the Corporation  shall, at the option of the holder of such shares, pay
in cash to such  holder  the full  amount of any such  dividends  or allow  such
dividends to be converted into Common Stock in accordance  with, and pursuant to
the terms specified in, Section 5 hereof,  except that the Conversion  Price (as
that term is defined in Section  5(a)) for such  purpose  shall be the then fair
market value of the Common Stock as  determined by the Board of Directors of the
Corporation.

     3. Liquidation, Dissolution or Winding Up.

     (a) In the event of any voluntary or involuntary  liquidation,  dissolution
or winding up of the  Corporation,  the  holders of shares of Series C Preferred
Stock then  outstanding  shall be  entitled  to be paid out of the assets of the
Corporation available for distribution to its stockholders, after and subject to
the payment in full of all amounts  required to be distributed to the holders of
any other  class or series of stock of the  Corporation  ranking on  liquidation
prior and in preference to the Series C Preferred Stock  (collectively  referred
to as "Senior  Preferred  Stock"),  but before any payment  shall be made to the
holders of any Junior Securities by reason of their ownership thereof, an amount
equal to $4 per share  (subject to  appropriate  adjustment  in the event of any
stock  dividend,  stock split,  combination  or other  similar  recapitalization
affecting such shares). If upon any such liquidation,  dissolution or winding up
of the  Corporation  the  remaining  assets  of the  Corporation  available  for
distribution  to its  stockholders  shall be  insufficient to pay the holders of
shares  of Series C  Preferred  Stock the full  amount  to which  they  shall be
entitled,  the  holders of Series C Preferred  Stock shall share  ratably in any
distribution of the remaining  assets and funds of the Corporation in proportion
to the  respective  amounts  which would  otherwise be payable in respect of the
shares held by them upon such  distribution  if all  amounts  payable on or with
respect to such shares were paid in full.

     (b) After the payment of all  preferential  amounts  required to be paid to
the  holders of Senior  Preferred  Stock and Series C  Preferred  Stock upon the
dissolution, liquidation or winding up of the Corporation, the holders of shares
of Junior Securities then outstanding shall be

                                       4



entitled to receive the remaining assets and funds of the Corporation  available
for distribution to its stockholders.

     (c) Written notice of such liquidation,  dissolution or winding up, stating
a payment date and the place where said payments  shall be made,  shall be given
by mail, postage prepaid,  or by telex to non-U.S.  residents,  not less than 20
days prior to the payment date stated  therein,  to the holders of record of the
Series C Preferred Stock, such notice to be addressed to each such holder at its
address as shown by the records of the Corporation.

     (d)  Whenever  the  distribution  provided  for in this  Section 3 shall be
payable in property other than cash, the value of such distribution shall be the
fair market value of such  property as  determined in good faith by the Board of
Directors of the Corporation.

     (e) For the  purposes  of this  Section  3,  neither  the  voluntary  sale,
conveyance, exchange or transfer (for cash, shares of stock, securities or other
consideration)  of all or  substantially  all of the  property  or assets of the
Corporation nor the  consolidation or merger of the Corporation with one or more
other corporations  shall be deemed to be a liquidation,  dissolution or winding
up, voluntary or involuntary,  unless such voluntary sale, conveyance,  exchange
or transfer shall be in connection  with a plan of  liquidation,  dissolution or
winding up of the business of the Corporation.

     4. Voting

     (a)  Except as may be  otherwise  provided  in these  terms of the Series C
Preferred Stock or by law, the Series C Preferred Stock shall not be entitled to
vote.

     (b) The  Corporation  shall not  amend,  alter or repeal  the  preferences,
special  rights or other powers of the Series C Preferred  Stock so as to affect
adversely  the  Series  C  Preferred  Stock,  without  the  written  consent  or
affirmative vote of the holders of a majority of the then outstanding  shares of
Series C Preferred Stock,  given in writing or by vote at a meeting,  consenting
or voting (as the case may be) separately as a class. For this purpose,  without
limiting the generality of the foregoing,  the  authorization or issuance of any
series of Series  Preferred  Stock with preference or priority over the Series C
Preferred  Stock  as to  the  right  to  receive  either  dividends  or  amounts
distributable

                                       5


upon  liquidation,  dissolution or winding up of the Corporation shall be deemed
to affect  adversely  the Series C Preferred  Stock,  and the  authorization  or
issuance  of any  series of Series  Preferred  Stock on a parity  with  Series C
Preferred  Stock  as to  the  right  to  receive  either  dividends  or  amounts
distributable  upon  liquidation,  dissolution or winding up of the  Corporation
shall not be deemed to affect adversely the Series C Preferred Stock. The number
of authorized  shares of Series C Preferred  Stock may be increased or decreased
(but not below the number of shares then outstanding) by the affirmative vote of
the holders of a majority of the then  outstanding  shares of the Common  Stock,
Series C  Preferred  Stock  and all  other  classes  or  series  of stock of the
Corporation entitled to vote thereon, voting as a single class.

     5. Optional  Conversion.  The holders of the Series C Preferred Stock shall
have conversion rights as follows (the "Conversion Rights"):

     (a) Right to  Convert.  Each  share of Series C  Preferred  Stock  shall be
convertible,  at the option of the holder thereof,  at any time and from time to
time, into such number of fully paid and nonassessable shares of Common Stock as
is determined by dividing  $4.00 by the  Conversion  Price (as defined below) in
effect at the time of conversion. The conversion price at which shares of Common
Stock shall be deliverable  upon  conversion of Series C Preferred Stock without
the payment of additional  consideration  by the holder thereof (the "Conversion
Price") shall initially be $8.00. Such initial Conversion Price, and the rate at
which shares of Series C Preferred  Stock may be converted into shares of Common
Stock, shall be subject to adjustment as provided below.

     In the event of a notice of  redemption of any shares of Series C Preferred
Stock  pursuant  to  Section  6 hereof,  the  Conversion  Rights  of the  shares
designated for redemption  shall terminate at the close of business on the fifth
full day preceding the date fixed for redemption, unless the redemption price is
not paid when due, in which case the  Conversion  Rights for such  shares  shall
continue  until such price is paid in full. In the event of a liquidation of the
Corporation,  the Conversion  Rights shall terminate at the close of business on
the first  full day  preceding  the date fixed for the  payment  of any  amounts
distributable on liquidation to the holders of Series C Preferred Stock.

     (b) Fractional Shares. No fractional shares of Common Stock shall be issued
upon  conversion  of the Series C  Preferred  Stock.  In lieu of any  fractional
shares to which the holder would otherwise be entitled,  the  Corporation  shall
pay cash equal to such  fraction  multiplied  by the then  effective  Conversion
Price.

     (c) Mechanics of Conversion.

         (i) In order for a holder of Series C Preferred Stock to convert shares
         of Series C Preferred Stock


                                       6


         into  shares  of  Common  Stock,   such  holder  shall   surrender  the
         certificate or certificates for such shares of Series C Preferred Stock
         at the office of the  transfer  agent for the Series C Preferred  Stock
         (or at the  principal  office  of the  Corporation  if the  Corporation
         serves as its own transfer  agent),  together with written  notice that
         such  holder  elects to convert  all or any number of the shares of the
         Series  C  Preferred   Stock   represented   by  such   certificate  or
         certificates.  Such notice shall state such  holder's name or the names
         of the  nominees  in  which  such  holder  wishes  the  certificate  or
         certificates  for shares of Common  Stock to be issued.  If required by
         the  Corporation,  certificates  surrendered  for  conversion  shall be
         endorsed or  accompanied  by a written  instrument  or  instruments  of
         transfer,  in a form satisfactory to the Corporation,  duly executed by
         the  registered  holder  or his  or its  attorney  duly  authorized  in
         writing.  The date of  receipt of such  certificates  and notice by the
         transfer agent (or by the Corporation if the Corporation  serves as its
         own transfer agent) shall be the conversion date  ("Conversion  Date").
         The  Corporation  shall,  as soon as  practicable  after the Conversion
         Date,  issue and  deliver  at such  office  to such  holder of Series C
         Preferred  Stock,  or  to  his  or  its  nominees,   a  certificate  or
         certificates  for the  number of shares of Common  Stock to which  such
         holder shall be entitled, together with cash in lieu of any fraction of
         a share.

                  (ii) The  Corporation  shall at all  times  when the  Series C
         Preferred Stock shall be outstanding, reserve and keep available out of
         its  authorized  but unissued  stock,  for the purpose of effecting the
         conversion  of the Series C  Preferred  Stock,  such number of its duly
         authorized  shares  of  Common  Stock  as  shall  from  time to time be
         sufficient  to  effect  the  conversion  of all  outstanding  Series  C
         Preferred  Stock.  Before  taking  any  action  which  would  cause  an
         adjustment  reducing the  Conversion  Price below the then par value of
         the shares of Common Stock  issuable  upon  conversion  of the Series C
         Preferred  Stock,  the Corporation will take any corporate action which
         may,  in the opinion of its  counsel,  be  necessary  in order that the
         Corporation may validly and legally issue fully paid and  nonassessable
         shares of Common Stock at such adjusted Conversion Price.

                  (iii)  Upon  any  such   conversion,   no  adjustment  to  the
         Conversion  Price shall be made for any accrued and unpaid dividends on
         the Series C  Preferred  Stock  surrendered  for  conversion  or on the
         Common Stock delivered upon conversion.



                                       7


                  (iv) All shares of Series C  Preferred  Stock which shall have
         been  surrendered  for conversion as herein provided shall no longer be
         deemed to be  outstanding  and all rights with  respect to such shares,
         including  the rights,  if any, to receive  notices and to vote,  shall
         immediately cease and terminate on the Conversion Date, except only the
         right of the  holders  thereof  to  receive  shares of Common  Stock in
         exchange  therefor  and  payment of any  accrued  and unpaid  dividends
         thereon.  Any shares of Series C Preferred  Stock so converted shall be
         retired and canceled and shall not be reissued, and the Corporation may
         from time to time take such  appropriate  action as may be necessary to
         reduce the authorized Series C Preferred Stock accordingly.

         (d)      Adjustments to Conversion Price for Diluting Issues:

                  (i)      Special Definitions.  For purposes of this Subsection
         5(d), the following definitions shall apply:

                           (A) "Option"  shall mean rights,  options or warrants
         to  subscribe  for,  purchase  or  otherwise  acquire  Common  Stock or
         Convertible  Securities,  excluding  options  granted to  employees  or
         consultants  of the  Corporation  pursuant to an option plan adopted by
         the Board of Directors (subject to appropriate adjustment for any stock
         dividend,  stock split,  combination or other similar  recapitalization
         affecting such shares).

                           (B)  "Original  Issue  Date"  shall  mean the date on
         which a share of Series C Preferred Stock was first issued.

                           (C) "Convertible Securities" shall mean any evidences
         of  indebtedness,  shares or other  securities  directly or  indirectly
         convertible into or exchangeable for Common Stock.

                           (D)  "Additional  Shares of Common  Stock" shall mean
         all shares of Common Stock issued (or, pursuant to Subsection 5(d)(iii)
         below, deemed to be issued) by the Corporation after the Original Issue
         Date, other than shares of Common Stock issued or issuable:

                                    (I) upon  conversion  of  shares of Series C
                  Preferred Stock outstanding on the Original Issue Date;

                                    (II) as a dividend or distribution on Series
                  C Preferred Stock;

  
                                       8


                                 (III) by reason of a dividend,  stock split,
                  split-up  or other  distribution  on shares  of  Common  Stock
                  excluded from the  definition  of Additional  Shares of Common
                  Stock by the  foregoing  clauses  (I) and (II) or this  clause
                  (III); or

                                  (IV) upon the  exercise of options  excluded
                  from the definition of "Option" in Subsection 5(d)(i)(A).

                  (ii) No Adjustment of Conversion  Price.  No adjustment in the
         number of shares of Common  Stock  into  which the  Series C  Preferred
         Stock is  convertible  shall be made by  adjustment  in the  applicable
         Conversion  Price  thereof:  (a)  unless  the  consideration  per share
         (determined  pursuant to Subsection 5(d)(v)) for an Additional Share of
         Common Stock issued or deemed to be issued by the  Corporation  is less
         than the  applicable  Conversion  Price in effect  on the date of,  and
         immediately  prior to, the issue of such Additional  Shares,  or (b) if
         prior to such issuance,  the Corporation  receives  written notice from
         the  holders of at least a majority of the then  outstanding  shares of
         Series C Preferred Stock agreeing that no such adjustment shall be made
         as the result of the issuance of Additional Shares of Common Stock.

                  (iii) Issue of Securities Deemed Issue of Additional Shares of
         Common Stock. If the Corporation at any time or from time to time after
         the  Original  Issue  Date  shall  issue  any  Options  or  Convertible
         Securities or shall fix a record date for the  determination of holders
         of any class of  securities  entitled  to receive  any such  Options or
         Convertible  Securities,  then the  maximum  number of shares of Common
         Stock (as set forth in the instrument  relating  thereto without regard
         to any provision contained therein for a subsequent  adjustment of such
         number)  issuable  upon the exercise of such Options or, in the case of
         Convertible Securities and Options therefor, the conversion or exchange
         of such Convertible Securities, shall be deemed to be Additional Shares
         of Common  Stock issued as of the time of such issue or, in case such a
         record date shall have been fixed,  as of the close of business on such
         record date,  provided that Additional Shares of Common Stock shall not
         be  deemed to have  been  issued  unless  the  consideration  per share
         (determined  pursuant to Subsection  5(d)(v) hereof) of such Additional
         Shares of Common  Stock  would be less than the  applicable  Conversion
         Price in effect on the date of and immediately  prior to such issue, or
         such record date, as the case may be, and provided  further that in any


                                        9



         such case in which  Additional  Shares of Common Stock are deemed to be
         issued:

                           (A) no further  adjustment  in the  Conversion  Price
         shall be made upon the subsequent  issue of  Convertible  Securities or
         shares of Common Stock upon the exercise of such Options or  conversion
         or exchange of such Convertible Securities;

                           (B) if such  Options  or  Convertible  Securities  by
         their terms  provide,  with the passage of time or  otherwise,  for any
         increase in the consideration  payable to the Corporation,  or decrease
         in the number of shares of Common Stock  issuable,  upon the  exercise,
         conversion or exchange thereof,  the Conversion Price computed upon the
         original  issue  thereof (or upon the  occurrence of a record date with
         respect thereto), and any subsequent adjustments based thereon,  shall,
         upon any such increase or decrease becoming effective, be recomputed to
         reflect such increase or decrease insofar as it affects such Options or
         the rights of conversion or exchange under such Convertible Securities;

                           (C) no  readjustment  pursuant  to  clause  (B) above
         shall have the effect of increasing the  Conversion  Price to an amount
         which  exceeds the lower of (i) the  Conversion  Price on the  original
         adjustment  date, or (ii) the Conversion Price that would have resulted
         from any  issuance of  Additional  Shares of Common  Stock  between the
         original adjustment date and such readjustment date;

                           (D)  upon  the   expiration  or  termination  of  any
         unexercised  Option, the Conversion Price shall not be readjusted,  but
         the  Additional  Shares of Common Stock deemed  issued as the result of
         the original  issue of such Option  shall not be deemed  issued for the
         purposes of any subsequent adjustment of the Conversion Price; and

                           (E) in the  event  of any  change  in the  number  of
         shares  of Common  Stock  issuable  upon the  exercise,  conversion  or
         exchange  of any Option or  Convertible  Security,  including,  but not
         limited  to,  a  change  resulting  from  the  antidilution  provisions
         thereof,  the  Conversion  Price  then in  effect  shall  forthwith  be
         readjusted to such Conversion Price as would have been obtained had the
         adjustment  which  was  made  upon  the  issuance  of  such  Option  or
         Convertible  Security not  exercised or converted  prior to such change
         been made  upon the basis of such  change,  but no  further  adjustment
         shall be made for the actual issuance of

                                       10



         Common Stock  upon the exercise  or conversion  of any  such  Option or
         Convertible Security.

                  (iv)   Adjustment  of   Conversion   Price  Upon  Issuance  of
         Additional  Shares of Common Stock. In the event the Corporation  shall
         at any time after the Original  Issue Date issue  Additional  Shares of
         Common Stock (including  Additional Shares of Common Stock deemed to be
         issued pursuant to Subsection 5(d)(iii), but excluding shares issued as
         a dividend or  distribution  as provided in  Subsection  5(f) or upon a
         stock split or  combination  as provided in Subsection  5(e)),  without
         consideration or for a consideration per share less than the applicable
         Conversion Price in effect on the date of and immediately prior to such
         issue, then, and in such event, such Conversion Price shall be reduced,
         concurrently  with such issue,  to a price  (calculated  to the nearest
         cent)  determined by multiplying  such Conversion  Price by a fraction,
         (A) the  numerator of which shall be (1) the number of shares of Common
         Stock  outstanding  immediately prior to such issue plus (2) the number
         of shares of Common Stock which the aggregate consideration received by
         the  Corporation  for the total number of  Additional  Shares of Common
         Stock so issued would purchase at such  Conversion  Price;  and (B) the
         denominator  of which  shall be the  number of  shares of Common  Stock
         outstanding  immediately  prior to such  issue  plus the number of such
         Additional  Shares of Common Stock so issued;  provided  that,  for the
         purpose  of this  Subsection  5(d)(iv),  all  shares  of  Common  Stock
         issuable  upon  conversion  of  shares  of  Series  C  Preferred  Stock
         outstanding  immediately  prior to such  issue  shall be  deemed  to be
         outstanding,  and  immediately  after any  Additional  Shares of Common
         Stock are deemed issued  pursuant to Subsection  5(d)(iii)  (other than
         shares  excluded from the  definition of  "Additional  Shares of Common
         Stock"  by  virtue  of  clause  (IV) of  Subsection  5(d)(i)(D)),  such
         Additional Shares of Common Stock shall be deemed to be outstanding.

                  Notwithstanding the foregoing, the applicable Conversion Price
         shall not be so reduced  at such time if the  amount of such  reduction
         would be an amount less than $.05, but any such amount shall be carried
         forward and  reduction  with  respect  thereto  made at the time of and
         together with any subsequent reduction which, together with such amount
         and any other  amount or amounts so carried  forward,  shall  aggregate
         $.05 or more.

                  (v)  Determination  of  Consideration.  For  purposes  of this
         Subsection 5(d), the consideration  received by the Corporation for the
         issue of any  Additional  Shares of Common  Stock  shall be computed as
         follows:


                                       11



                           (A)      Cash and Property: Such consideration shall:

                                    (I)  insofar  as it  consists  of  cash,  be
                  computed at the aggregate of cash received by the Corporation,
                  excluding  amounts  paid or payable  for  accrued  interest or
                  accrued dividends;

                                    (II)  insofar  as it  consists  of  property
                  other than cash,  be computed at the fair market value thereof
                  at the time of such issue,  as determined in good faith by the
                  Board of Directors; and

                                    (III)  in the  event  Additional  Shares  of
                  Common  Stock  are  issued   together  with  other  shares  or
                  securities   or   other   assets   of  the   Corporation   for
                  consideration  which covers both,  be the  proportion  of such
                  consideration so received, computed as provided in clauses (I)
                  and (II) above,  as  determined  in good faith by the Board of
                  Directors.

                           (B)   Options   and   Convertible   Securities.   The
         consideration  per share  received by the  Corporation  for  Additional
         Shares  of  Common  Stock  deemed  to  have  been  issued  pursuant  to
         Subsection  5(d)(iii)  relating to Options and  Convertible  Securities
         shall be determined by dividing (x) the total amount,  if any, received
         or receivable by the Corporation as consideration for the issue of such
         Options or Convertible Securities, plus the minimum aggregate amount of
         additional  consideration  (as set  forth in the  instruments  relating
         thereto,  without  regard  to any  provision  contained  therein  for a
         subsequent adjustment of such consideration) payable to the Corporation
         upon the exercise of such Options or the conversion or exchange of such
         Convertible  Securities,  or in the  case of  Options  for  Convertible
         Securities, the exercise of such Options for Convertible Securities and
         the conversion or exchange of such Convertible  Securities,  by (y) the
         maximum  number  of  shares  of  Common  Stock  (as  set  forth  in the
         instruments relating thereto, without regard to any provision contained
         therein for a subsequent  adjustment of such number)  issuable upon the
         exercise  of  such  Options  or the  conversion  or  exchange  of  such
         Convertible Securities.

         (e) Adjustment for Stock Splits and  Combinations.  If the  Corporation
shall at any time or from  time to time  after  the  Original  Issue  Date for a
series of Preferred Stock effect a subdivision of the outstanding  Common Stock,
the Conversion Price then in effect immediately before that


                                       12


subdivision shall be proportionately  decreased. If the Corporation shall at any
time or from time to time  after  the  Original  Issue  Date for a series of the
Preferred Stock combine the outstanding  shares of Common Stock,  the Conversion
Price then in effect immediately before the combination shall be proportionately
increased.  Any adjustment  under this paragraph  shall become  effective at the
close of business on the date the subdivision or combination becomes effective.

         (f) Adjustment for Certain  Dividends and  Distributions.  In the event
the  Corporation at any time, or from time to time after the Original Issue Date
for a series of  Preferred  Stock shall make or issue,  or fix a record date for
the determination of holders of Common Stock entitled to receive,  a dividend or
other  distribution  payable in additional  shares of Common Stock,  then and in
each such event the Conversion  Price for such series of Preferred Stock then in
effect shall be decreased as of the time of such  issuance or, in the event such
a record date shall have been fixed,  as of the close of business on such record
date, by  multiplying  the Conversion  Price for such series of Preferred  Stock
then in effect by a fraction:

                  (i) the numerator of which shall be the total number of shares
         of Common Stock issued and outstanding immediately prior to the time of
         such issuance or the close of business on such record date, and

                  (ii) the  denominator  of which  shall be the total  number of
         shares of Common Stock issued and outstanding  immediately prior to the
         time of such issuance or the close of business on such record date plus
         the  number of  shares of Common  Stock  issuable  in  payment  of such
         dividend or distribution;  provided, however, if such record date shall
         have  been  fixed  and  such  dividend  is not  fully  paid  or if such
         distribution  is  not  fully  made  on the  date  fixed  therefor,  the
         Conversion Price for such series of Preferred Stock shall be recomputed
         accordingly  as of the  close  of  business  on such  record  date  and
         thereafter  the  Conversion  Price for such series of  Preferred  Stock
         shall be adjusted  pursuant to this  paragraph as of the time of actual
         payment of such dividends or distributions.

         (g) Adjustments for Other Dividends and Distributions. In the event the
Corporation at any time or from time to time after the Original Issue Date for a
series of  Preferred  Stock  shall


                                       13



make or issue, or fix a record date for the  determination  of holders of Common
Stock  entitled  to  receive,  a  dividend  or  other  distribution  payable  in
securities of the  Corporation  other than shares of Common  Stock,  then and in
each such event  provision  shall be made so that the  holders of such series of
Preferred Stock shall receive upon conversion  thereof in addition to the number
of shares of Common Stock receivable thereupon,  the amount of securities of the
Corporation  that they  would  have  received  had their  Preferred  Stock  been
converted into Common Stock on the date of such event and had thereafter, during
the period from the date of such event to and  including  the  conversion  date,
retained  such  securities  receivable  by them as aforesaid  during such period
giving application to all adjustments called for during such period,  under this
paragraph with respect to the rights of the holders of the Preferred Stock.

         (h) Adjustment for Reclassification,  Exchange or Substitution.  If the
Common  Stock  issuable  upon the  conversion  of the  Preferred  Stock shall be
changed into the same or a different number of shares of any class or classes of
stock, whether by capital reorganization,  reclassification, or otherwise (other
than a  subdivision  or  combination  of shares or stock  dividend  provided for
above, or a reorganization,  merger,  consolidation,  or sale of assets provided
for  below),  then and in each  such  event the  holder  of each  such  share of
Preferred  Stock shall have the right  thereafter to convert such share into the
kind and amount of shares of stock and other securities and property  receivable
upon such reorganization,  reclassification,  or other change, by holders of the
number of shares of Common Stock into which such shares of Preferred Stock might
have been converted immediately prior to such reorganization,  reclassification,
or change, all subject to further adjustment as provided herein.

         (i)  Adjustment  for  Merger  or  Reorganization,  etc.  In case of any
consolidation or merger of the Corporation  with or into another  corporation or
the sale of all or substantially all of the assets of the Corporation to another
corporation  (other than a  consolidation,  merger or sale which is treated as a
liquidation pursuant to Subsection 3(a)), each share of Series C Preferred Stock
shall  thereafter be convertible  into the kind and amount of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock of the Corporation  deliverable upon conversion of such Series C Preferred
Stock would have been entitled upon such consolidation,  merger or sale; and, in
such case,  appropriate  adjustment (as determined in good faith by the Board of
Directors)  shall be made in the application of the provisions in this Section 5
set forth with respect to the rights and interest  thereafter  of the holders of
the Series C Preferred  Stock,  to the end that the provisions set forth in this
Section 5 (including provisions with respect to changes in and other adjustments
of the Conversion Price) shall thereafter be applicable, as nearly as reasonably
may be,  in  relation  to any  shares  of  stock or  other  property


                                       14



thereafter deliverable upon the conversion of the Series C Preferred Stock.

         (j) No  Impairment.  The  Corporation  will not,  by  amendment  of its
Certificate of Incorporation or through any reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation,  but will at
all times in good faith assist in the carrying out of all the provisions of this
Section  5 and in the  taking  of  all  such  action  as  may  be  necessary  or
appropriate  in order to protect  the  Conversion  Rights of the  holders of the
Series C Preferred Stock against impairment.

         (k)  Certificate  as  to  Adjustments.  Upon  the  occurrence  of  each
adjustment or readjustment  of the Conversion  Price pursuant to this Section 5,
the  Corporation,  at its expense,  shall  promptly  compute such  adjustment or
readjustment  in accordance  with the terms hereof and furnish to each holder of
Series  C  Preferred  Stock a  certificate  setting  forth  such  adjustment  or
readjustment  and  showing in detail the facts  upon  which such  adjustment  or
readjustment is based.  The Corporation  shall,  upon the written request at any
time of any holder of Series C Preferred Stock, furnish or cause to be furnished
to such holder a similar  certificate  setting  forth (i) such  adjustments  and
readjustments, (ii) the Conversion Price then in effect, and (iii) the number of
shares of Common  Stock and the  amount,  if any, of other  property  which then
would be received upon the conversion of Series C Preferred Stock.

         (1)      Notice of Record Date.  In the event:

                   (i) that the  Corporation  declares a dividend  (or any other
         distribution)  on its Common  Stock  payable  in Common  Stock or other
         securities of the Corporation;

                   (ii)  that  the   Corporation   subdivides  or  combines  its
         outstanding shares of Common Stock;

                   (iii)  of any  reclassification  of the  Common  Stock of the
         Corporation (other than a subdivision or combination of its outstanding
         shares  of  Common  Stock or a stock  dividend  or  stock  distribution
         thereon),  or of any consolidation or merger of the Corporation into or
         with another corporation, or of the sale of all or substantially all of
         the assets of the Corporation; or

                   (iv) of the involuntary or voluntary dissolution, liquidation
         or winding up of the Corporation;


                                       15



then the Corporation  shall cause to be filed at its principal  office or at the
office of the transfer agent of the Series C Preferred Stock, and shall cause to
be mailed to the holders of the Series C Preferred Stock at their last addresses
as shown on the records of the  Corporation or such transfer agent, at least ten
days prior to the record date  specified  in (A) below or twenty days before the
date specified in (B) below, a notice stating

                           (A) the record date of such  dividend,  distribution,
         subdivision  or  combination,  or, if a record is not to be taken,  the
         date as of which the  holders of Common  Stock of record to be entitled
         to such dividend,  distribution,  subdivision or combination  are to be
         determined, or

                           (B)  the   date  on  which   such   reclassification,
         consolidation,  merger, sale, dissolution, liquidation or winding up is
         expected to become  effective,  and the date as of which it is expected
         that  holders of Common  Stock of record  shall be entitled to exchange
         their  shares  of  Common  Stock  for   securities  or  other  property
         deliverable upon such  reclassification,  consolidation,  merger, sale,
         dissolution or winding up.

     6. Optional Redemption.

     (a) At any time and from time to time after June 30, 1993, the  Corporation
may,  at the option of its Board of  Directors,  redeem  the Series C  Preferred
Stock,  in whole or in part,  by  paying $6 per share  (subject  to  appropriate
adjustment  for stock splits,  stock  dividends,  combinations  or other similar
recapitalization  affecting  such  shares)  in cash for each  share of  Series C
Preferred  Stock  then  redeemed  (hereinafter  referred  to as the  "Redemption
Price").

     (b) In the event of any  redemption of only a part of the then  outstanding
Series C Preferred Stock, the Corporation  shall effect such redemption pro rata
among the  holders  thereof  based on the number of shares of Series C Preferred
Stock held by such  holders  on the date of the  Redemption  Notice (as  defined
below).

     (c) `At least 30 days prior to the date fixed for any  redemption of Series
C Preferred Stock (hereinafter  referred to as the "Redemption  Date"),  written
notice shall be mailed, by first class or registered mail,  postage prepaid,  to
each holder of record of Series C Preferred Stock to be redeemed,  at his or its
address  last  shown  on the  records  of the  transfer  agent  of the  Series C
Preferred  Stock (or the  records  of the  Corporation,  if it serves as its own
transfer  agent),  notifying  such holder of the election of the  Corporation to
redeem such shares,  specifying the  Redemption 


                                       16



Date and the date on which such holder's  Conversion Rights (pursuant to Section
5 hereof) as to such shares  terminate and calling upon such holder to surrender
to the Corporation,  in the manner and at the place designated,  his, her or its
certificate or certificates  representing the shares to be redeemed (such notice
is  hereinafter  referred  to as the  "Redemption  Notice").  On or prior to the
Redemption  Date,  each holder of Series C Preferred  Stock to be redeemed shall
surrender his, her or its certificate or certificates  representing  such shares
to the Corporation,  in the manner and at the place designated in the Redemption
Notice,  and thereupon the  Redemption  Price of such shares shall be payable to
the order of the person whose name appears on such  certificate or  certificates
as the owner thereof and each surrendered  certificate shall be canceled. In the
event less than all the shares represented by any such certificate are redeemed,
a new certificate shall be issued  representing the unredeemed shares.  From and
after the Redemption  Date,  unless there shall has been a default in payment of
the Redemption  Price, all rights of the holders of the Series C Preferred Stock
designated  for  redemption  in the  Redemption  Notice as  holders  of Series C
Preferred Stock of the  Corporation  (except the right to receive the Redemption
Price without  interest upon  surrender of their  certificate  or  certificates)
shall cease with respect to such shares, and such shares shall not thereafter be
transferred on the books of the  Corporation or be deemed to be outstanding  for
any purpose whatsoever.

         (d) Subject to the  provisions  hereof,  the Board of  Directors of the
Corporation  shall have  authority  to  prescribe  the manner in which  Series C
Preferred  Stock  shall be  redeemed  from time to time.  Any shares of Series C
Preferred  Stock so redeemed shall  permanently  be retired,  shall no longer be
deemed  outstanding and shall not under any  circumstances be reissued,  and the
Corporation  may  from  time to time  take  such  appropriate  action  as may be
necessary to reduce the authorized Series C Preferred Stock accordingly. Nothing
herein contained shall prevent or restrict the purchase by the Corporation, from
time to time either at public or private  sale,  of the whole or any part of the
Series  C  Preferred  Stock at such  price  or  prices  as the  Corporation  may
determine, subject to the provisions of applicable law.


              [THE REMAINDER OF THIS PAGE INTENTIONALLY LEFT BLANK]


                                       17



                     DESIGNATION OF SERIES D PREFERRED STOCK

         1.  Designation;  Rank.  The series of Preferred  Stock  designated and
known as "Series D Preferred Stock" shall consist of 1,000,000 shares, par value
$.01 per share.  Shares of the Series D Preferred  Stock shall,  with respect to
dividend  rights and rights on  liquidation,  winding up and  dissolution,  rank
senior and prior to the Common  Stock,  par value  $.004 per share (the  "Common
Stock") of the Corporation and junior to the Series C Preferred Stock.

         2. Dividends.

         (a) The  holders of the Series D  Preferred  Stock shall be entitled to
receive,  when  declared by the  Directors  out of any funds  legally  available
therefor,  dividends in cash at the annual rate of $0.2375 per share (subject to
appropriate adjustment for stock splits, stock dividends,  combinations or other
similar  recapitalizations  affecting  such  shares),  and  no  more,  in  equal
quarterly payments in arrears on March 31, June 30, September 30 and December 31
in each year  (each  such date is  referred  to as a  "Dividend  Payment  Date")
commencing on March 31, 1994,  payable in preference and priority to any payment
of any cash  dividend on Common Stock and junior in  preference  and priority to
any payment of any cash  dividend  to the  holders of Series C Preferred  Stock.
Such  dividends  shall be paid to the holders of record at the close of business
on the date  specified by the Board of Directors of the  Corporation at the time
such  dividend  is  declared;  provided,  however,  that the  amount  payable to
shareholders  for the  first  such  dividend  due on March  31,  1994,  shall be
pro-rated on a daily basis from the date of issue. If the Dividend  Payment Date
is not a business  day, the Dividend  Payment Date shall be the next  succeeding
business day.

         (b) Each of such  quarterly  dividends  shall be fully  cumulative  and
shall accrue, whether or not earned or declared, without interest, from the date
of issue of the Series D Preferred Stock.

         (c) No dividends  shall be declared or paid or set apart for payment on
the  Common  Stock,  or on the  Preferred  Stock of any  series  ranking,  as to
dividends,  junior to the Series D Preferred  Stock,  for any period unless full
cumulative  dividends have been or  contemporaneously  are declared and paid (or
declared  and a sum  sufficient  for the  payment  thereof  set  apart  for such
payment) on the Series D Preferred Stock for all dividend payment periods ending
on or prior to the date of  payment  of such  full  cumulative  dividends.  (The
Common Stock and any such series of Preferred  Stock are referred to hereinafter
as  "Junior  Securities".)  Unless  full  cumulative  dividends  on the Series D
Preferred Stock have been paid, no other


                                       18


distribution shall be made upon or in respect of the Junior Securities.

     (d) In the event that the Corporation  shall have  cumulative,  accrued and
unpaid  dividends  outstanding  immediately  prior  to,  and in the  event  of a
conversion  of any shares of Series D  Preferred  Stock as provided in Section 5
hereof,  the Corporation  shall,  at its option,  pay in cash to such holder the
full amount of any such  dividends or allow such  dividends to be converted into
Common Stock and the  conversion  price for such purpose  shall be the then fair
market value of the Common Stock as  determined by the Board of Directors of the
Corporation.

     3. Liquidation, Dissolution or Winding Up.

     (a) In the event of any voluntary or involuntary  liquidation,  dissolution
or winding up of the  Corporation,  the  holders of shares of Series D Preferred
Stock then  outstanding  shall be  entitled  to be paid out of the assets of the
Corporation available for distribution to its stockholders, after and subject to
the payment in full of all amounts  required to be distributed to the holders of
any other  class or series of stock of the  Corporation  ranking on  liquidation
prior and in preference to the Series D Preferred Stock,  (collectively referred
to as "Senior  Preferred  Stock")  but before any  payment  shall be made to the
holders of any Junior Securities by reason of their ownership thereof, an amount
equal to $4.75 per share (subject to appropriate  adjustment in the event of any
stock  dividend,  stock split,  combination  or other  similar  recapitalization
affecting such shares). If upon any such liquidation,  dissolution or winding up
of the  Corporation  the  remaining  assets  of the  Corporation  available  for
distribution  to its  stockholders  shall be  insufficient to pay the holders of
shares  of Series D  Preferred  Stock the full  amount  to which  they  shall be
entitled,  the  holders of Series D Preferred  Stock shall share  ratably in any
distribution of the remaining  assets and funds of the Corporation in proportion
to the  respective  amounts  which would  otherwise be payable in respect of the
shares held by them upon such  distribution  if all  amounts  payable on or with
respect to such shares were paid in full.

     (b) After the payment of all  preferential  amounts  required to be paid to
the  holders of Senior  Preferred  Stock and Series D  Preferred  Stock upon the
dissolution, liquidation or winding up of the Corporation, the holders of shares
of Junior Securities then outstanding shall be entitled to receive the remaining
assets  and  funds  of  the  Corporation   available  for  distribution  to  its
stockholders.

     (c) Written notice of such liquidation,  dissolution or winding up, stating
a payment date and the place where said


                                       19



payments  shall  be  made,  shall be  given  by  mail,  postage  prepaid,  or by
telecopier  to  non-U.S.  residents,  not less than 20 days prior to the payment
date stated therein,  to the holders of record of the Series D Preferred  Stock,
such notice to be  addressed  to each such holder at its address as shown by the
records of the Corporation.

         (d) Whenever the  distribution  provided for in this Section 3 shall be
payable in property other than cash, the value of such distribution shall be the
fair market value of such  property as  determined in good faith by the Board of
Directors of the Corporation.

         (e) For the  purposes of this Section 3,  neither the  voluntary  sale,
conveyance, exchange or transfer (for case, shares of stock, securities or other
consideration)  of all or  substantially  all of the  property  or assets of the
Corporation nor the  consolidation or merger of the Corporation with one or more
other corporations  shall be deemed to be a liquidation,  dissolution or winding
up, voluntary or involuntary,  unless such voluntary sale, conveyance,  exchange
or transfer shall be in connection  with a plan of  liquidation,  dissolution or
winding up of the business of the Corporation.

         4.       Voting.

         (a) Except as may be otherwise  provided in these terms of the Series D
Preferred Stock or by law, the Series D Preferred Stock shall not be entitled to
vote.

         (b) The Corporation  shall not amend,  alter or repeal the preferences,
special  rights or other powers of the Series D Preferred  Stock so as to affect
adversely  the  Series  D  Preferred  Stock,  without  the  written  consent  or
affirmative vote of the holders of a majority of the then outstanding  shares of
Series D Preferred Stock,  given in writing or by vote at a meeting,  consenting
or voting (as the case may be) separately as a class. For this purpose,  without
limiting the generality of the foregoing,  the  authorization or issuance of any
series  of  Preferred  Stock  with  preference  or  priority  over the  Series D
Preferred  Stock  as to  the  right  to  receive  either  dividends  or  amounts
distributable  upon  liquidation,  dissolution or winding up of the  Corporation
shall be  deemed to affect  adversely  the  Series D  Preferred  Stock,  and the
authorization  or  issuance  of any series of  Preferred  Stock on a parity with
Series D Preferred Stock as to the right to receive either  dividends or amounts
distributable  upon  liquidation,  dissolution or winding up of the  Corporation
shall be deemed not to affect adversely the Series D Preferred Stock. The number
of authorized  shares of Series D Preferred  Stock may be increased or decreased
(but not below the number of shares then outstanding) by the affirmative vote of
the holders of


                                       20


a  majority  of the  then  outstanding  shares  of the  Common  Stock,  Series D
Preferred  Stock and all  other  classes  or series of stock of the  Corporation
entitled to vote thereon, voting as a single class.

         5.       Optional Conversion.  The holders of the Series D Preferred 
Stock shall have conversion rights as follows (the "Conversion Rights"):

         (a) Right to Convert.  Each share of Series D Preferred  Stock shall be
convertible, at the option of the holder thereof, at any time, into one share of
fully paid and nonassessable Common Stock (subject to appropriate  adjustment in
the event of any stock  dividend,  stock  split,  combination  or other  similar
recapitalization affecting such shares).

         In the  event of a notice  of  redemption  of any  shares  of  Series D
Preferred  Stock  pursuant  to Section 6 hereof,  the  Conversion  Rights of the
shares designated for redemption shall terminate at the close of business on the
fifth full day preceding the date fixed for  redemption,  unless the  redemption
price is not paid when due, in which case the Conversion  Rights for such shares
shall  continue  until such price is paid in full. In the event of a liquidation
of the  Corporation,  the  Conversion  Rights  shall  terminate  at the close of
business on the first full day  preceding  the date fixed for the payment of any
amounts distributable on liquidation to the holders of Series D Preferred Stock.

         (b) Fractional  Shares.  No fractional  shares of Common Stock shall be
issued  upon  conversion  of the  Series  D  Preferred  Stock.  In  lieu  of any
fractional  shares  to  which  the  holder  would  otherwise  be  entitled,  the
Corporation  shall  pay  cash  equal  to such  fraction  multiplied  by the then
effective Conversion Price.

         (c) Mechanics of Conversion.

                  (i) In order  for a holder  of  Series  D  Preferred  Stock to
         convert shares of Series D Preferred Stock into shares of Common Stock,
         such holder shall surrender the  certificate or  certificates  for such
         shares of Series D Preferred  Stock at the office of the transfer agent
         for the Series D  Preferred  Stock (or at the  principal  office of the
         Corporation  if the  Corporation  serves  as its own  transfer  agent),
         together with written  notice that such holder elects to convert all or
         any number of the shares of the Series D Preferred Stock represented by
         such  certificate  or  certificates  for  shares of Common  stock to be
         issued,  provided however, that the holder shall pay any transfer taxes
         arising  from the  issuance of the Common Stock to any person or entity
         other than the holder.  


                                       21



         If required by the Corporation, certificates surrendered for conversion
         shall be endorsed or accompanied by a written instrument or instruments
         of transfer,  in a form satisfactory to the Corporation,  duly executed
         by the  registered  holder or his or its attorney  duly  authorized  in
         writing.  The date of  receipt of such  certificates  and notice by the
         transfer agent (or by the Corporation if the Corporation  serves as its
         own transfer agent) shall be the conversion date  ("Conversion  Date").
         The  Corporation  shall,  as soon as  practicable  after the Conversion
         Date,  issue and  deliver  at such  office  to such  holder of Series D
         Preferred  Stock,  or  to  his  or  its  nominees,   a  certificate  or
         certificates  for the  number of shares of Common  Stock to which  such
         holder shall be entitled, together with cash in lieu of any fraction of
         a share.

                  (ii) The  Corporation  shall at all  times  when the  Series D
         Preferred Stock shall be outstanding, reserve and keep available out of
         is  authorized  but unissued  stock,  for the purpose of effecting  the
         conversion  of the Series D  Preferred  Stock,  such number of its duly
         authorized  shares  of  Common  Stock  as  shall  from  time to time be
         sufficient  to  effect  the  conversion  of all  outstanding  Series  D
         Preferred Stock.

                  (iii) All shares of Series D Preferred  Stock which shall have
         been  surrendered  for conversion as herein provided shall no longer be
         deemed to be  outstanding  and all rights with  respect to such shares,
         including  the rights,  if any, to receive  notices and to vote,  shall
         immediately cease and terminate on the Conversion Date, except only the
         right of the  holders  thereof  to  receive  shares of Common  Stock in
         exchange  therefor  and  payment of any  accrued  and unpaid  dividends
         thereon.  Any shares of Series D Preferred  Stock so converted shall be
         retired and canceled and shall not be reissued, and the Corporation may
         from time to time take such  appropriate  action as may be necessary to
         reduce the authorized Series D Preferred Stock accordingly.

         (d) Adjustment for Reclassification,  Exchange, or Substitution. If the
Common Stock issuable upon the conversion of the Series D Preferred  Stock shall
be changed into the same or a different number of shares of any class or classes
of stock,  whether by capital  reorganization,  reclassification,  or  otherwise
(other than a subdivision or  combination  of shares or stock dividend  provided
for above in section 5(a) hereof, or a reorganization, merger, consolidation, or
sale of assets  provided  for below in Section  5(e)  hereof),  then and in each
event the holder of each such share of Series D  Preferred  Stock shall have the


                                       22


right thereafter to convert such share of Series D Preferred Stock into the kind
and  amount  of  shares  of stock  and  other  securities  receivable  upon such
reorganization,  reclassification,  or other change by a holder of the number of
shares of Common Stock into which such shares of Series D Preferred  Stock might
have been converted immediately prior to such reorganization,  reclassification,
or change, all subject to further adjustment as provided herein.

         (e)  Adjustment  for  Merger  or  Reorganization,  etc.  In case of any
consolidation or merger of the Corporation  with or into another  corporation or
the sale of all or substantially all of the assets of the Corporation to another
corporation  (other than a  consolidation,  merger or sale which is treated as a
liquidation pursuant to Subsection 3(a)), each share of Series D Preferred Stock
shall  thereafter be convertible  into the kind and amount of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock of the Corporation  deliverable upon conversion of such Series D Preferred
Stock would have been entitled upon such consolidation,  merger or sale; and, in
such case,  appropriate  adjustment (as determined in good faith by the Board of
Directors)  shall be made in the application of the provisions in this Section 5
with respect to the rights and interest  thereafter of the holders of the Series
D Preferred  Stock,  to the end that the  provisions set forth in this Section 5
shall  thereafter be applicable,  as nearly as reasonably may be, in relation to
any shares of stock or other property thereafter deliverable upon the conversion
of the Series D Preferred Stock.

         (f) No  Impairment.  The  Corporation  will not,  by  amendment  of its
Certificate of Incorporation or through any reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation,  but will at
all times in good faith assist in the carrying out of all the provisions of this
section  5 and in the  taking  of  all  such  action  as  may  be  necessary  or
appropriate  in order to protect  the  Conversion  Rights of the  holders of the
Series D Preferred Stock against impairment.

         (g)      Notice of Record Date.  In the event:

                  (i) that the  Corporation  declares a  dividend  (or any other
         distribution)  on its Common  Stock  payable  in Common  Stock or other
         securities of the Corporation;

                  (ii)  that  the   Corporation   subdivides   or  combines  its
         outstanding shares of Common Stock;


                                       23



                  (iii)  of any  reclassification  of the  Common  Stock  of the
         Corporation (other than a subdivision or combination of its outstanding
         shares  of  Common  Stock or a stock  dividend  or  stock  distribution
         thereon),  or of any consolidation or merger of the Corporation into or
         with another corporation, or of the sale of all or substantially all of
         the assets of the Corporation; or

                  (iv) of the involuntary or voluntary dissolution,  liquidation
         or winding up of the Corporation;

then the Corporation  shall cause to be filed at its principal  office or at the
office of the transfer agent of the Series D Preferred Stock, and shall cause to
be mailed to the holders of the Series D Preferred Stock at their last addresses
as shown on the records of the  Corporation or such transfer agent, at least ten
days prior to the record date  specified  in (A) below or twenty days before the
date specified in (B) below, a notice stating

                           (A) the record date of such  dividend,  distribution,
         subdivision  or  combination,  or, if a record is not to be taken,  the
         date as of which the  holders of Common  Stock of record to be entitled
         to such dividend,  distribution,  subdivision or combination  are to be
         determined, or

                           (B)  the   date  on  which   such   reclassification,
         consolidation,  merger, sale, dissolution, liquidation or winding up is
         expected to become  effective,  and the date as of which it is expected
         that  holders of Common  Stock of record  shall be entitled to exchange
         their  shares  of  Common  Stock  for   securities  or  other  property
         deliverable upon such  reclassification,  consolidation,  merger, sale,
         dissolution or winding up.

         6.       Optional Redemption.

         (a) At any time and from  time to time,  the  Corporation  may,  at the
option of its Board of Directors,  redeem the Series D Preferred Stock, in whole
or in part, by paying $7 per share (subject to appropriate  adjustment for stock
splits,  stock  dividends,   combinations  or  other  similar  recapitalizations
affecting  such shares) in cash for each share of Series D Preferred  Stock then
redeemed (hereinafter referred to as the "Redemption Price").

         (b) In the  event  of  any  redemption  of  only  a  part  of the  then
outstanding  Series  D  Preferred  Stock,  the  Corporation  shall  effect  such
redemption  pro rata among the holders  thereof based on the number of shares of
Series D  Preferred  Stock  held of  record by such  holders  on the date of the
Redemption Notice (as defined below).


                                       24



         (c) At least 30 days  prior to the date  fixed  for any  redemption  of
Series D Preferred Stock  (hereinafter  referred to as the  "Redemption  Date"),
written notice shall be mailed,  by first class mail,  postage prepaid,  to each
holder  of  record of Series D  Preferred  Stock to be  redeemed,  at his or its
address  last  shown  on the  records  of the  transfer  agent  of the  Series D
Preferred  Stock (or the  records  of the  Corporation,  if it serves as its own
transfer  agent),  notifying  such holder of the election of the  Corporation to
redeem such shares  specifying  the  Redemption  Date and the date on which such
holder's  Conversion  Rights  (pursuant  to Section 5 hereof) as to such  shares
terminate and calling upon such holder to surrender to the  Corporation,  in the
manner and at the place designated,  his, her or its certificate or certificates
representing  the shares to be redeemed (such notice is hereinafter  referred to
as the "Redemption  Notice"). On or prior to the Redemption Date, each holder of
Series  D  Preferred  Stock  to be  redeemed  shall  surrender  his,  her or its
certificate or certificates representing such shares to the Corporation,  in the
manner and at the place designated in the Redemption  Notice,  and thereupon the
Redemption  Price of such  shares  shall be  payable  to the order of the person
whose name appears on such  certificate or certificates as the owner thereof and
each surrendered  certificate shall be canceled.  In the event less than all the
shares represented by any such certificate are redeemed, a new certificate shall
be issued  representing  the  unredeemed  shares.  From and after the Redemption
Date, unless there shall have been a default in payment of the Redemption Price,
all  rights of the  holders  of the  Series D  Preferred  Stock  designated  for
redemption in the  Redemption  Notice as holders of Series D Preferred  Stock of
the  Corporation  (except  the right to receive  the  Redemption  Price  without
interest upon surrender of their  certificate or certificates)  shall cease with
respect to such shares,  and such shares shall not  thereafter be transferred on
the books of the  Corporation  or be deemed to be  outstanding  for any  purpose
whatsoever.

         (d) Subject to the  provisions  hereof,  the Board of  Directors of the
Corporation  shall have  authority  to  prescribe  the manner in which  Series D
Preferred  Stock  shall be  redeemed  from time to time.  Any shares of Series D
Preferred  Stock so redeemed shall  permanently  be retired,  shall no longer be
deemed  outstanding and shall not under any  circumstances be reissued,  and the
Corporation  may  from  time to time  take  such  appropriate  action  as may be
necessary to reduce the authorized Series D Preferred Stock accordingly. Nothing
herein contained shall prevent or restrict the purchase by the Corporation, from
time to time either at public or private  sale,  of the whole or any part of the
Series  D  Preferred  Stock at such  price  or  prices  as the  Corporation  may
determine, subject to the provisions of applicable law.


                                       25



                     DESIGNATION OF SERIES E PREFERRED STOCK

         1.  Designation;  Rank.  The series of Preferred  Stock  designated and
known as "Series E Preferred  Stock" shall consist of 400,000 shares,  par value
$.01 per share.  Shares of the Series E Preferred  Stock shall,  with respect to
dividend  rights and rights on  liquidation,  winding up and  dissolution,  rank
senior and prior to the Common  Stock,  par value  $.004 per share (the  "Common
Stock")  of the  Corporation,  junior to the Series C  Preferred  Stock and on a
parity with the Series D Preferred Stock and Series F Preferred Stock.

         2.       Dividends.

         (a) The  holders of the Series E  Preferred  Stock shall be entitled to
receive,  when  declared by the  Directors  out of any funds  legally  available
therefor, dividends in cash or, at the Corporation's option, in Common Stock, at
the annual rate of $0.30 per share (subject to appropriate  adjustment for stock
splits,  stock  dividends,   combinations  or  other  similar  recapitalizations
affecting  such  shares),  and no  more,  on the  earlier  to  occur  of (i) the
Conversion  Date (as  hereinafter  defined)  and (ii)  the  Redemption  Date (as
hereinafter  defined) (the "Dividend  Payment Date"),  payable in preference and
priority  to any  payment  of any cash  dividend  on  Common  Stock,  junior  in
preference  and  priority  to any  dividend  payment to the  holders of Series C
Preferred  Stock and on a parity  with any  dividend  payment to the  holders of
Series D Preferred Stock and Series F Preferred  Stock.  Such dividends shall be
paid to the holders of record at the close of business on the  Dividend  Payment
Date. If the Dividend  Payment Date is not a business day, the Dividend  Payment
Date shall be the next succeeding business day. If the Corporation elects to pay
such dividends in Common Stock,  the conversion price per share (the "Conversion
Price") shall be the lesser of (i) $3.75 and (ii) the closing price per share of
the Common  Stock on the  principal  national  securities  exchange on which the
Common  Stock is then  listed or  admitted  to trading or, if not then listed or
admitted to trading on any such exchange,  on the NASDAQ National Market System,
or if not then listed or traded on any such  exchange  or system,  the bid price
per share on the NASDAQ  Small-Cap  Market,  averaged  over the 30 trading  days
immediately preceding the Conversion Date (subject to appropriate  adjustment in
the event of any stock  dividend,  stock  split,  combination  or other  similar
recapitalization affecting such shares).

         (b) Dividends  shall be fully  cumulative and shall accrue,  whether or
not earned or declared, without interest, from the date of issue of the Series E
Preferred Stock.


                                       26



         (c) No dividends  shall be declared or paid or set apart for payment on
the  Common  Stock,  or on the  Preferred  Stock of any  series  ranking,  as to
dividends,  junior to or on a parity with the Series E Preferred  Stock, for any
period  unless full  cumulative  dividends  have been or  contemporaneously  are
declared and paid (or declared and a sum sufficient for the payment  thereof set
apart for such payment) on the Series E Preferred Stock for all dividend payment
periods  ending  on or prior  to the date of  payment  of such  full  cumulative
dividends. (The Common Stock and any such series of Preferred Stock are referred
to hereinafter as "Junior  Securities".) Unless full cumulative dividends on the
Series E Preferred  Stock have been paid,  no other  distribution  shall be made
upon or in respect of the Junior Securities.

         3.       Liquidation, Dissolution or Winding Up.

         (a)  In  the  event  of  any  voluntary  or  involuntary   liquidation,
dissolution or winding up of the Corporation,  the holders of shares of Series E
Preferred Stock then outstanding  shall be entitled to be paid out of the assets
of the Corporation  available for  distribution to its  stockholders,  after and
subject to the payment in full of all amounts  required to be distributed to the
holders  of any other  class or series of stock of the  Corporation  ranking  on
liquidation   prior  and  in  preference  to  the  Series  E  Preferred   Stock,
(collectively  referred to as "Senior  Preferred  Stock") but before any payment
shall  be made to the  holders  of any  Junior  Securities  by  reason  of their
ownership  thereof,  and on a parity with any dividend payment to the holders of
Series D Preferred Stock and Series F Preferred  Stock, an amount equal to $3.75
per share (subject to appropriate adjustment in the event of any stock dividend,
stock  split,  combination  or other  similar  recapitalization  affecting  such
shares).  If  upon  any  such  liquidation,  dissolution  or  winding  up of the
Corporation the remaining  assets of the Corporation  available for distribution
to its stockholders shall be insufficient to pay the holders of shares of Series
E Preferred  Stock the full amount to which they shall be entitled,  the holders
of Series E  Preferred  Stock  shall share  ratably in any  distribution  of the
remaining  assets and funds of the  Corporation  in proportion to the respective
amounts  which would  otherwise be payable in respect of the shares held by them
upon such  distribution if all amounts payable on or with respect to such shares
were paid in full.

         (b) After the payment of all  preferential  amounts required to be paid
to the holders of Senior  Preferred  Stock and Series E Preferred Stock upon the
dissolution, liquidation or winding up of the Corporation, the holders of shares
of Junior Securities then outstanding shall be 


                                       27


entitled to receive the remaining assets and funds of the Corporation  available
for distribution to its stockholders.

         (c)  Written  notice of such  liquidation,  dissolution  or winding up,
stating a payment date and the place where said payments shall be made, shall be
given by mail, postage prepaid, or by telecopier to non-U.S. residents, not less
than 20 days prior to the payment date stated therein,  to the holders of record
of the Series E Preferred Stock, such notice to be addressed to each such holder
at its address as shown by the records of the Corporation.

         (d) Whenever the  distribution  provided for in this Section 3 shall be
payable in property other than cash, the value of such distribution shall be the
fair market value of such  property as  determined in good faith by the Board of
Directors of the Corporation.

         (e) For the  purposes of this Section 3,  neither the  voluntary  sale,
conveyance, exchange or transfer (for case, shares of stock, securities or other
consideration)  of all or  substantially  all of the  property  or assets of the
Corporation nor the  consolidation or merger of the Corporation with one or more
other corporations  shall be deemed to be a liquidation,  dissolution or winding
up, voluntary or involuntary,  unless such voluntary sale, conveyance,  exchange
or transfer shall be in connection  with a plan of  liquidation,  dissolution or
winding up of the business of the Corporation.

         4.       Voting.

         (a) Except as may be otherwise  provided in these terms of the Series E
Preferred Stock or by law, the Series E Preferred Stock shall not be entitled to
vote.

         (b) The Corporation  shall not amend,  alter or repeal the preferences,
special  rights or other powers of the Series E Preferred  Stock so as to affect
adversely  the  Series  E  Preferred  Stock,  without  the  written  consent  or
affirmative vote of the holders of a majority of the then outstanding  shares of
Series E Preferred Stock,  given in writing or by vote at a meeting,  consenting
or voting (as the case may be) separately as a class. For this purpose,  without
limiting the generality of the foregoing,  the  authorization or issuance of any
series  of  Preferred  Stock  with  preference  or  priority  over the  Series E
Preferred  Stock  as to  the  right  to  receive  either  dividends  or  amounts
distributable  upon  liquidation,  dissolution or winding up of the  Corporation
shall be  deemed to affect  adversely  the  Series E  Preferred  Stock,  and the
authorization  or  issuance  of any series of  Preferred  Stock on a parity with
Series E Preferred Stock as to the right to receive either  dividends or amounts
distributable  upon  liquidation,  dissolution or


                                       28


winding up of the Corporation shall be deemed not to affect adversely the Series
E Preferred Stock.  The number of authorized  shares of Series E Preferred Stock
may be  increased  or  decreased  (but not  below  the  number  of  shares  then
outstanding)  by the  affirmative  vote of the holders of a majority of the then
outstanding  shares of the Common Stock,  Series E Preferred Stock and all other
classes or series of stock of the Corporation  entitled to vote thereon,  voting
as a single class.

         5.       Conversion.

         (a) Mandatory  Conversion.  On January 1, 1995 (the "Conversion Date"),
each share of Series E Preferred Stock shall  automatically  and without further
action on the part of any holder of Series E Preferred  Stock be converted  into
the number of shares of fully paid and  nonassessable  Common  Stock  derived by
dividing  $3.75 by the Conversion  Price.  Upon such  conversion,  each share of
Series E Preferred Stock shall be cancelled and not subject to reissuance. On or
before  September 30, 1994, the  Corporation  shall provide  written notice (the
"Conversion Notice") to the holders hereof of the Corporation's intention not to
exercise the redemption option provided for in Section 6 hereof and to allow the
Series E Preferred Stock to automatically convert pursuant to this Section 5(a).
The immediately preceding sentence notwithstanding, the Corporation shall not be
deemed to have waived its right to redeem the Series E Preferred  Stock pursuant
to Section 6 hereof by virtue of the issuance of the Conversion Notice."

         (b) Delivery of Stock Certificates.  The holder of any shares of Series
E Preferred  Stock converted  pursuant to Section 5(a) hereof,  shall deliver to
the  Corporation  during  regular  business  hours at the office of the transfer
agent of the  Corporation  for the Series E  Preferred  Stock,  or at such other
place as may be designated by the  Corporation,  the certificate or certificates
for the  shares  so  converted,  duly  endorsed  or  assigned  in  blank  to the
Corporation.  As promptly as practicable thereafter, the Corporation shall issue
and  deliver  to  such  holder,  at the  place  designated  by  such  holder,  a
certificate  or  certificates  for the number of shares of Common Stock to which
such  holder is  entitled.  The  person in whose name the  certificate  for such
Common  Stock is to be issued  shall be deemed to have become a  stockholder  of
record on the Conversion  Date unless the transfer books of the  Corporation are
closed  on that  date,  in  which  event he shall  be  deemed  to have  become a
stockholder  of record on the next  succeeding  date on which the transfer books
are open.

         (c) Fractional  Shares.  No fractional  shares of Common Stock shall be
issued  upon  conversion  of the  Series  E  Preferred  Stock.  In  lieu  of any
fractional  shares  to  which

                                       29



the holder would otherwise be entitled,  the Corporation shall pay cash equal to
such fraction multiplied by the Conversion Price.

         (d) Adjustment for Stock Splits and  Combinations.  If the  Corporation
shall at any time or from time to time after the date on which a share of Series
E Preferred Stock was first issued  ("Original Issue Date") effect a subdivision
of the outstanding Common Stock, the Conversion Price then in effect immediately
before that subdivision shall be proportionately  decreased.  If the Corporation
shall at any time or from time to time after the Original Issue Date combine the
outstanding  shares  of  Common  Stock,  the  Conversion  Price  then in  effect
immediately  before the  combination  shall be  proportionately  increased.  Any
adjustment  under this paragraph shall become effective at the close of business
on the date the subdivision or combination becomes effective.

         (e) Adjustment for Certain  Dividends and  Distributions.  In the event
the  Corporation at any time, or from time to time after the Original Issue Date
shall make or issue,  or fix a record date for the  determination  of holders of
Common Stock entitled to receive,  a dividend or other  distribution  payable in
additional  shares of Common Stock,  then and in each such event the  Conversion
Price for the Series E Preferred  Stock then in effect  shall be decreased as of
the time of such  issuance  or, in the event such a record  date shall have been
fixed,  as of the close of business  on such record  date,  by  multiplying  the
Conversion Price for the Series E Preferred Stock then in effect by a fraction:

                  (i) the numerator of which shall be the total number of shares
         of Common Stock issued and outstanding immediately prior to the time of
         such issuance or the close of business on such record date, and

                  (ii) the  denominator  of which  shall be the total  number of
         shares of Common Stock issued and outstanding  immediately prior to the
         time of such issuance or the close of business on such record date plus
         the  number of  shares of Common  Stock  issuable  in  payment  of such
         dividend or distribution;  provided, however, if such record date shall
         have  been  fixed  and  such  dividend  is not  fully  paid  or if such
         distribution  is  not  fully  made  on the  date  fixed  therefor,  the
         Conversion  Price for the Series E Preferred  Stock shall be recomputed
         accordingly  as of the  close  of  business  on such  record  date  and
         thereafter the Conversion  Price for the Series E Preferred Stock shall
         be adjusted pursuant to this paragraph as of the time of actual payment
         of such dividends or distributions.



                                       30


         (f) Adjustments for Other Dividends and Distributions. In the event the
Corporation at any time or from time to time after the Original Issue Date shall
make or issue, or fix a record date for the  determination  of holders of Common
Stock  entitled  to  receive,  a  dividend  or  other  distribution  payable  in
securities of the  Corporation  other than shares of Common  Stock,  then and in
each such  event  provision  shall be made so that the  holders  of the Series E
Preferred Stock shall receive upon conversion  thereof in addition to the number
of shares of Common Stock receivable thereupon,  the amount of securities of the
Corporation  that they  would  have  received  had their  Preferred  Stock  been
converted into Common Stock on the date of such event and had thereafter, during
the period from the date of such event to and  including  the  conversion  date,
retained  such  securities  receivable  by them as aforesaid  during such period
giving application to all adjustments called for during such period,  under this
paragraph with respect to the rights of the holders of the Preferred Stock.

         (g) Adjustment for Reclassification,  Exchange, or Substitution. If the
Common Stock issuable upon the conversion of the Series E Preferred  Stock shall
be changed into the same or a different number of shares of any class or classes
of stock,  whether by capital  reorganization,  reclassification,  or  otherwise
(other than a subdivision or  combination  of shares or stock dividend  provided
for  in  Sections  5(d),  (e)  and  (f)  hereof,  or a  reorganization,  merger,
consolidation,  or sale of assets provided for in Section 5(h) hereof), then and
in each event the holder of each such share of Series E  Preferred  Stock  shall
have the right thereafter to convert such share of Series E Preferred Stock into
the kind and amount of shares of stock and other securities receivable upon such
reorganization,  reclassification,  or other change by a holder of the number of
shares of Common Stock into which such shares of Series E Preferred  Stock might
have been converted immediately prior to such reorganization,  reclassification,
or change, all subject to further adjustment as provided herein.

         (h)  Adjustment  for  Merger  or  Reorganization,  etc.  In case of any
consolidation or merger of the Corporation  with or into another  corporation or
the sale of all or substantially all of the assets of the Corporation to another
corporation  (other than a  consolidation,  merger or sale which is treated as a
liquidation pursuant to Subsection 3(a)), each share of Series E Preferred Stock
shall  thereafter be convertible  into the kind and amount of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock of the Corporation  deliverable upon conversion of such Series E Preferred
Stock would have been entitled upon such consolidation,  merger or sale; and, in
such case,  appropriate  adjustment (as determined in good faith by the 


                                       31


Board of Directors)  shall be made in the  application of the provisions in this
Section 5 with respect to the rights and interest  thereafter  of the holders of
the Series E Preferred  Stock,  to the end that the provisions set forth in this
Section 5 shall  thereafter be  applicable,  as nearly as reasonably  may be, in
relation to any shares of stock or other property  thereafter  deliverable  upon
the conversion of the Series E Preferred Stock.

         (i) No  Impairment.  The  Corporation  will not,  by  amendment  of its
Certificate of Incorporation or through any reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation,  but will at
all times in good faith assist in the carrying out of all the provisions of this
Section  5 and in the  taking  of  all  such  action  as  may  be  necessary  or
appropriate  in order to protect  the  holders of the Series E  Preferred  Stock
against impairment of their conversion rights.

         (j)      Notice of Record Date.  In the event:

                  (i) that the  Corporation  declares a  dividend  (or any other
         distribution)  on its Common  Stock  payable  in Common  Stock or other
         securities of the Corporation;

                  (ii)  that  the   Corporation   subdivides   or  combines  its
         outstanding shares of Common Stock;

                  (iii)  of any  reclassification  of the  Common  Stock  of the
         Corporation (other than a subdivision or combination of its outstanding
         shares  of  Common  Stock or a stock  dividend  or  stock  distribution
         thereon),  or of any consolidation or merger of the Corporation into or
         with another corporation, or of the sale of all or substantially all of
         the assets of the Corporation; or

                  (iv) of the involuntary or voluntary dissolution,  liquidation
         or winding up of the Corporation;

then the Corporation  shall cause to be filed at its principal  office or at the
office of the transfer agent of the Series E Preferred Stock, and shall cause to
be mailed to the holders of the Series E Preferred Stock at their last addresses
as shown on the records of the  Corporation or such transfer agent, at least ten
(10) days prior to the record  date  specified  in (A) below or twenty (20) days
before the date specified in (B) below, a notice stating

                           (A) the record date of such  dividend,  distribution,
         subdivision  or  combination,  or, if a record is not to be taken,  the
         date as of which the

                                       32



         holders  of Common  Stock of record to be  entitled  to such  dividend,
         distribution, subdivision or combination are to be determined, or

                           (B)  the   date  on  which   such   reclassification,
         consolidation,  merger, sale, dissolution, liquidation or winding up is
         expected to become  effective,  and the date as of which it is expected
         that  holders of Common  Stock of record  shall be entitled to exchange
         their  shares  of  Common  Stock  for   securities  or  other  property
         deliverable upon such  reclassification,  consolidation,  merger, sale,
         dissolution or winding up.

                  (k) Optional  Conversion.  Except as set forth in Section 5(a)
hereof,  the holders of the Series E Preferred Stock shall not have the right to
convert their shares of Series E Preferred Stock into Common Stock.

         6.       Optional Redemption.

         (a) At any time and from time to time on or before  December  31, 1994,
the Corporation may, at the option of its Board of Directors,  redeem the Series
E Preferred  Stock,  in whole or in part, by paying $3.75 per share  (subject to
appropriate adjustment for stock splits, stock dividends,  combinations or other
similar  recapitalizations  affecting  such  shares)  in cash for each  share of
Series  E  Preferred  Stock  then  redeemed  (hereinafter  referred  to  as  the
"Redemption Price").

         (b) In the  event  of  any  redemption  of  only  a  part  of the  then
outstanding  Series  E  Preferred  Stock,  the  Corporation  shall  effect  such
redemption  pro rata among the holders  thereof based on the number of shares of
Series E  Preferred  Stock  held of  record by such  holders  on the date of the
Redemption Notice (as defined below).

         (c) At least ten (10) days prior to the date  fixed for any  redemption
of Series E Preferred Stock (hereinafter  referred to as the "Redemption Date"),
written notice shall be mailed,  by first class mail,  postage prepaid,  to each
holder  of  record of Series E  Preferred  Stock to be  redeemed,  at his or its
address  last  shown  on the  records  of the  transfer  agent  of the  Series E
Preferred  Stock (or the  records  of the  Corporation,  if it serves as its own
transfer  agent),  notifying  such holder of the election of the  Corporation to
redeem such shares  specifying the Redemption  Date and calling upon such holder
to surrender to the Corporation, in the manner and at the place designated, his,
her or its  certificate or certificates  representing  the shares to be redeemed
(such notice is hereinafter referred to as the "Redemption Notice"). On or prior
to the Redemption  Date,  each holder of Series E Preferred Stock to be redeemed
shall surrender his, her or its certificate or  


                                       33



certificates  representing such shares to the Corporation,  in the manner and at
the place  designated in the  Redemption  Notice,  and thereupon the  Redemption
Price of such  shares  shall be payable  to the order of the  person  whose name
appears  on such  certificate  or  certificates  as the owner  thereof  and each
surrendered certificate shall be canceled. In the event less than all the shares
represented by any such  certificate are redeemed,  a new  certificate  shall be
issued  representing the unredeemed shares.  From and after the Redemption Date,
unless there shall have been a default in payment of the Redemption  Price,  all
rights of the holders of the Series E Preferred Stock  designated for redemption
in the  Redemption  Notice  as  holders  of  Series  E  Preferred  Stock  of the
Corporation  (except the right to receive the Redemption  Price without interest
upon surrender of their certificate or certificates) shall cease with respect to
such shares, and such shares shall not thereafter be transferred on the books of
the Corporation or be deemed to be outstanding for any purpose whatsoever.

         (d) Subject to the  provisions  hereof,  the Board of  Directors of the
Corporation  shall have  authority  to  prescribe  the manner in which  Series E
Preferred  Stock  shall be  redeemed  from time to time.  Any shares of Series E
Preferred  Stock so redeemed shall  permanently  be retired,  shall no longer be
deemed  outstanding and shall not under any  circumstances be reissued,  and the
Corporation  may  from  time to time  take  such  appropriate  action  as may be
necessary to reduce the authorized Series E Preferred Stock accordingly. Nothing
herein contained shall prevent or restrict the purchase by the Corporation, from
time to time either at public or private  sale,  of the whole or any part of the
Series  E  Preferred  Stock at such  price  or  prices  as the  Corporation  may
determine, subject to the provisions of applicable law.

                                       34




                     DESIGNATION OF SERIES F PREFERRED STOCK

         1.  Designation;  Rank.  The series of Preferred  Stock  designated and
known as "Series F Preferred  Stock" shall consist of 700,000 shares,  par value
$.01 per share.  Shares of the Series F Preferred  Stock shall,  with respect to
dividend  rights and rights on  liquidation,  winding up and  dissolution,  rank
senior and prior to the Common  Stock,  par value  $.004 per share (the  "Common
Stock")  of the  Corporation,  junior to the Series C  Preferred  Stock and on a
parity with the Series D Preferred Stock and Series E Preferred Stock.

         2.       Dividends.  The holders of the Series F Preferred Stock shall 
not be entitled to receive dividends.

         3.       Liquidation, Dissolution or Winding Up.

         (a)  In  the  event  of  any  voluntary  or  involuntary   liquidation,
dissolution or winding up of the Corporation,  the holders of shares of Series F
Preferred Stock then outstanding  shall be entitled to be paid out of the assets
of the Corporation  available for  distribution to its  stockholders,  after and
subject to the payment in full of all amounts  required to be distributed to the
holders  of any other  class or series of stock of the  Corporation  ranking  on
liquidation   prior  and  in  preference  to  the  Series  F  Preferred   Stock,
(collectively  referred to as "Senior  Preferred  Stock") but before any payment
shall be made to the holders of Common Stock and any series of  Preferred  Stock
ranking  on  liquidation  junior  to  the  Series  F  Preferred  Stock  ("Junior
Securities")  by reason of their  ownership  thereof,  and on a parity  with any
dividend  payment  to the  holders  of Series D  Preferred  Stock  and  Series E
Preferred  Stock,  an amount  equal to $5.00 per share  (subject to  appropriate
adjustment in the event of any stock dividend, stock split, combination or other
similar  recapitalization  affecting such shares). If upon any such liquidation,
dissolution  or  winding  up of the  Corporation  the  remaining  assets  of the
Corporation available for distribution to its stockholders shall be insufficient
to pay the  holders  of shares of Series F  Preferred  Stock the full  amount to
which they shall be  entitled,  the  holders of Series F  Preferred  Stock shall
share  ratably  in any  distribution  of the  remaining  assets and funds of the
Corporation  in proportion to the  respective  amounts which would  otherwise be
payable  in respect of the  shares  held by them upon such  distribution  if all
amounts payable on or with respect to such shares were paid in full.

         (b) After the payment of all  preferential  amounts required to be paid
to the holders of Senior  Preferred  Stock and Series F Preferred Stock upon the
dissolution, 


                                       35


liquidation  or winding up of the  Corporation,  the holders of shares of Junior
Securities then  outstanding  shall be entitled to receive the remaining  assets
and funds of the Corporation available for distribution to its stockholders.

         (c)  Written  notice of such  liquidation,  dissolution  or winding up,
stating a payment date and the place where said payments shall be made, shall be
given by mail, postage prepaid, or by telecopier to non-U.S. residents, not less
than 20 days prior to the payment date stated therein,  to the holders of record
of the Series F Preferred Stock, such notice to be addressed to each such holder
at its address as shown by the records of the Corporation.

         (d) Whenever the  distribution  provided for in this Section 3 shall be
payable in property other than cash, the value of such distribution shall be the
fair market value of such  property as  determined in good faith by the Board of
Directors of the Corporation.

         (e) For the  purposes of this Section 3,  neither the  voluntary  sale,
conveyance, exchange or transfer (for case, shares of stock, securities or other
consideration)  of all or  substantially  all of the  property  or assets of the
Corporation nor the  consolidation or merger of the Corporation with one or more
other corporations  shall be deemed to be a liquidation,  dissolution or winding
up, voluntary or involuntary,  unless such voluntary sale, conveyance,  exchange
or transfer shall be in connection  with a plan of  liquidation,  dissolution or
winding up of the business of the Corporation.

         4.       Voting.

         (a) Except as may be otherwise  provided in these terms of the Series F
Preferred Stock or by law, the Series F Preferred Stock shall not be entitled to
vote.

         (b) The Corporation  shall not amend,  alter or repeal the preferences,
special  rights or other powers of the Series F Preferred  Stock so as to affect
adversely  the  Series  F  Preferred  Stock,  without  the  written  consent  or
affirmative vote of the holders of a majority of the then outstanding  shares of
Series F Preferred Stock,  given in writing or by vote at a meeting,  consenting
or voting (as the case may be) separately as a class. For this purpose,  without
limiting the generality of the foregoing,  the  authorization or issuance of any
series  of  Preferred  Stock  with  preference  or  priority  over the  Series F
Preferred  Stock  as to  the  right  to  receive  either  dividends  or  amounts
distributable  upon  liquidation,  dissolution or winding up of the  Corporation
shall be  deemed to affect  adversely  the  Series F  Preferred  Stock,  and the
authorization  or  issuance  of any series of  Preferred  Stock on a parity with
Series F


                                       36


Preferred  Stock  as to  the  right  to  receive  either  dividends  or  amounts
distributable  upon  liquidation,  dissolution or winding up of the  Corporation
shall be deemed not to affect adversely the Series F Preferred Stock. The number
of authorized  shares of Series F Preferred  Stock may be increased or decreased
(but not below the number of shares then outstanding) by the affirmative vote of
the holders of a majority of the then  outstanding  shares of the Common  Stock,
Series F  Preferred  Stock  and all  other  classes  or  series  of stock of the
Corporation entitled to vote thereon, voting as a single class.

         5.       Conversion.

         (a) Mandatory Conversion. On July 1, 1995 (the "Conversion Date"), each
share of Series F Preferred Stock shall automatically and without further action
on the part of any  holder of Series F  Preferred  Stock be  converted  into the
number  of  shares of fully  paid and  nonassessable  Common  Stock  derived  by
dividing the number 1 by a fraction,  the  denominator of which is $5.00 and the
numerator of which is ninety percent (90%) of the closing price per share of the
Common Stock on the principal national  securities  exchange on which the Common
Stock is then  listed or  admitted to trading or, if not then listed or admitted
to trading on any such exchange, on the NASDAQ National Market System, or if not
then listed or traded on any such exchange or system, the bid price per share on
the NASDAQ  Small-Cap  Market,  averaged  over the 30 trading  days  immediately
preceding the  Conversion  Date.  Upon such  conversion,  each share of Series F
Preferred Stock shall be cancelled and not subject to reissuance."

         (b) Delivery of Stock Certificates.  The holder of any shares of Series
F Preferred  Stock converted  pursuant to Section 5(a) hereof,  shall deliver to
the  Corporation  during  regular  business  hours at the office of the transfer
agent of the  Corporation  for the Series F  Preferred  Stock,  or at such other
place as may be designated by the  Corporation,  the certificate or certificates
for the  shares  so  converted,  duly  endorsed  or  assigned  in  blank  to the
Corporation.  As promptly as practicable thereafter, the Corporation shall issue
and  deliver  to  such  holder,  at the  place  designated  by  such  holder,  a
certificate  or  certificates  for the number of shares of Common Stock to which
such  holder is  entitled.  The  person in whose name the  certificate  for such
Common  Stock is to be issued  shall be deemed to have become a  stockholder  of
record on the Conversion  Date unless the transfer books of the  Corporation are
closed  on that  date,  in  which  event he shall  be  deemed  to have  become a
stockholder  of record on the next  succeeding  date on which the transfer books
are open.


                                       37



         (c) Fractional  Shares.  No fractional  shares of Common Stock shall be
issued  upon  conversion  of the  Series  F  Preferred  Stock.  In  lieu  of any
fractional  shares  to  which  the  holder  would  otherwise  be  entitled,  the
Corporation shall pay cash equal to such fraction multiplied by $5.00.

         (d) Adjustment for Stock Splits and  Combinations.  If the  Corporation
shall at any time or from time to time after the date on which a share of Series
F Preferred Stock was first issued  ("Original Issue Date") effect a subdivision
of the outstanding Common Stock, the Conversion Price then in effect immediately
before that subdivision shall be proportionately  decreased.  If the Corporation
shall at any time or from time to time after the Original Issue Date combine the
outstanding  shares  of  Common  Stock,  the  Conversion  Price  then in  effect
immediately  before the  combination  shall be  proportionately  increased.  Any
adjustment  under this paragraph shall become effective at the close of business
on the date the subdivision or combination becomes effective.

         (e) Adjustment for Certain  Dividends and  Distributions.  In the event
the  Corporation at any time, or from time to time after the Original Issue Date
shall make or issue,  or fix a record date for the  determination  of holders of
Common Stock entitled to receive,  a dividend or other  distribution  payable in
additional  shares of Common Stock,  then and in each such event the  Conversion
Price for the Series F Preferred  Stock then in effect  shall be decreased as of
the time of such  issuance  or, in the event such a record  date shall have been
fixed,  as of the close of business  on such record  date,  by  multiplying  the
Conversion Price for the Series F Preferred Stock then in effect by a fraction:

                  (i) the numerator of which shall be the total number of shares
         of Common Stock issued and outstanding immediately prior to the time of
         such issuance or the close of business on such record date, and

                  (ii) the  denominator  of which  shall be the total  number of
         shares of Common Stock issued and outstanding  immediately prior to the
         time of such issuance or the close of business on such record date plus
         the  number of  shares of Common  Stock  issuable  in  payment  of such
         dividend or distribution;  provided, however, if such record date shall
         have  been  fixed  and  such  dividend  is not  fully  paid  or if such
         distribution  is  not  fully  made  on the  date  fixed  therefor,  the
         Conversion  Price for the Series F Preferred  Stock shall be recomputed
         accordingly  as of the  close  of  business  on such  record  date  and
         thereafter the Conversion  Price for the Series F Preferred Stock shall
         be adjusted pursuant to this


                                       38


         paragraph  as  of  the  time  of  actual  payment of  such dividends or
         distributions.

         (f) Adjustments for Other Dividends and Distributions. In the event the
Corporation at any time or from time to time after the Original Issue Date shall
make or issue, or fix a record date for the  determination  of holders of Common
Stock  entitled  to  receive,  a  dividend  or  other  distribution  payable  in
securities of the  Corporation  other than shares of Common  Stock,  then and in
each such  event  provision  shall be made so that the  holders  of the Series F
Preferred Stock shall receive upon conversion  thereof in addition to the number
of shares of Common Stock receivable thereupon,  the amount of securities of the
Corporation  that they  would  have  received  had their  Preferred  Stock  been
converted into Common Stock on the date of such event and had thereafter, during
the period from the date of such event to and  including  the  conversion  date,
retained  such  securities  receivable  by them as aforesaid  during such period
giving application to all adjustments called for during such period,  under this
paragraph with respect to the rights of the holders of the Preferred Stock.

         (g) Adjustment for Reclassification,  Exchange, or Substitution. If the
Common Stock issuable upon the conversion of the Series F Preferred  Stock shall
be changed into the same or a different number of shares of any class or classes
of stock,  whether by capital  reorganization,  reclassification,  or  otherwise
(other than a subdivision or  combination  of shares or stock dividend  provided
for  in  Sections  5(d),  (e)  and  (f)  hereof,  or a  reorganization,  merger,
consolidation,  or sale of assets provided for in Section 5(h) hereof), then and
in each event the holder of each such share of Series F  Preferred  Stock  shall
have the right thereafter to convert such share of Series F Preferred Stock into
the kind and amount of shares of stock and other securities receivable upon such
reorganization,  reclassification,  or other change by a holder of the number of
shares of Common Stock into which such shares of Series F Preferred  Stock might
have been converted immediately prior to such reorganization,  reclassification,
or change, all subject to further adjustment as provided herein.

         (h)  Adjustment  for  Merger  or  Reorganization,  etc.  In case of any
consolidation or merger of the Corporation  with or into another  corporation or
the sale of all or substantially all of the assets of the Corporation to another
corporation  (other than a  consolidation,  merger or sale which is treated as a
liquidation pursuant to Subsection 3(a)), each share of Series F Preferred Stock
shall  thereafter be convertible  into the kind and amount of shares of stock or
other securities or property to which a holder of the number of shares of Common
Stock of the Corporation  deliverable upon conversion of such Series F 


                                       39



Preferred  Stock would have been  entitled  upon such  consolidation,  merger or
sale; and, in such case,  appropriate adjustment (as determined in good faith by
the Board of Directors)  shall be made in the  application  of the provisions in
this Section 5 with respect to the rights and interest thereafter of the holders
of the Series F Preferred  Stock,  to the end that the  provisions  set forth in
this Section 5 shall  thereafter be applicable,  as nearly as reasonably may be,
in relation to any shares of stock or other property thereafter deliverable upon
the conversion of the Series F Preferred Stock.

         (i) No  Impairment.  The  Corporation  will not,  by  amendment  of its
Certificate of Incorporation or through any reorganization,  transfer of assets,
consolidation,  merger,  dissolution,  issue or sale of  securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation,  but will at
all times in good faith assist in the carrying out of all the provisions of this
Section  5 and in the  taking  of  all  such  action  as  may  be  necessary  or
appropriate  in order to protect  the  holders of the Series F  Preferred  Stock
against impairment of their conversion rights.

         (j)      Notice of Record Date.  In the event:

                  (i) that the  Corporation  declares a  dividend  (or any other
         distribution)  on its Common  Stock  payable  in Common  Stock or other
         securities of the Corporation;

                  (ii)  that  the   Corporation   subdivides   or  combines  its
         outstanding shares of Common Stock;

                  (iii)  of any  reclassification  of the  Common  Stock  of the
         Corporation (other than a subdivision or combination of its outstanding
         shares  of  Common  Stock or a stock  dividend  or  stock  distribution
         thereon),  or of any consolidation or merger of the Corporation into or
         with another corporation, or of the sale of all or substantially all of
         the assets of the Corporation; or

                  (iv) of the involuntary or voluntary dissolution,  liquidation
         or winding up of the Corporation;

then the Corporation  shall cause to be filed at its principal  office or at the
office of the transfer agent of the Series F Preferred Stock, and shall cause to
be mailed to the holders of the Series F Preferred Stock at their last addresses
as shown on the records of the  Corporation or such transfer agent, at least ten
(10) days prior to the record  date  specified  in (A) below or twenty (20) days
before the date specified in (B) below, a notice stating


                                       40



                           (A) the record date of such  dividend,  distribution,
         subdivision  or  combination,  or, if a record is not to be taken,  the
         date as of which the  holders of Common  Stock of record to be entitled
         to such dividend,  distribution,  subdivision or combination  are to be
         determined, or

                           (B)  the   date  on  which   such   reclassification,
         consolidation,  merger, sale, dissolution, liquidation or winding up is
         expected to become  effective,  and the date as of which it is expected
         that  holders of Common  Stock of record  shall be entitled to exchange
         their  shares  of  Common  Stock  for   securities  or  other  property
         deliverable upon such  reclassification,  consolidation,  merger, sale,
         dissolution or winding up.

             (k)  Optional  Conversion.  Except  as set  forth in  Section  5(a)
hereof,  the holders of the Series F Preferred Stock shall not have the right to
convert their shares of Series F Preferred Stock into Common Stock.

         6. Redemption.  The Corporation  shall not have any right to redeem the
Series F Preferred Stock.

         FIFTH.  The Board of Directors shall have the power to adopt,  amend or
repeal the by-laws.

         SIXTH. No director shall be personally liable to the Corporation or its
stockholders  for  monetary  damages  for any breach of  fiduciary  duty by such
director as a director. Notwithstanding the foregoing sentence, a director shall
be liable to the  extent  provided  by  applicable  law,  (i) for  breach of the
director's duty of loyalty to the Corporation or its stockholders, (ii) for acts
or omissions  not in good faith or which  involve  intentional  misconduct  or a
knowing  violation of law, (iii) pursuant to Section 174 of the Delaware General
Corporation Law or (iv) for any transaction  from which the director  derived an
improper personal benefit. No amendment to or repeal of this Article Sixth shall
apply to or have  any  effect  on the  liability  or  alleged  liability  of any
director of the Corporation for or with respect to any acts or omissions of such
director occurring prior to such amendment.

         SEVENTH.  The number of  directors  constituting  the  entire  Board of
Directors  shall  be  as  set  forth  in or  pursuant  to  the  by-laws  of  the
Corporation.  The  Board of  Directors  shall be  divided  into  three  classes,
designated  Classes I, II and III,  which shall be as nearly  equal in number as
possible. Initially,  directors of Class I shall be elected to hold office for a
term expiring at the annual meeting of stockholders in 1995,  directors of Class
II shall be elected to hold office for a term expiring at the annual  meeting of
stockholders  in 1996 and directors of Class III


                                       41


shall be elected to hold  office for a term  expiring  at the annual  meeting of
stockholders  in 1997. At each annual  meeting of  stockholders  following  such
initial  classification  and election,  the respective  successors of each class
shall be elected for three-year terms.

         IN WITNESS WHEREOF, the Corporation has caused its corporate seal to be
affixed hereto and this Restated  Certificate of  Incorporation  to be signed by
its President and attested by its Secretary this day of June, 1994.
