Item 1.        General Information.

               (a)  The  Registrant  was organized as a Delaware  Corporation on
                    June 26, 1996.

               (b)  The  Registrant's  fiscal  year ends on  December 31 of each
                    year.

Item 2.        Transaction of Succession.

                  (a) The Registrant is the successor to Orion Network  Systems,
Inc., a Delaware  corporation  organized in 1982 ("Old  Orion") and a registrant
under Section 12(g) of the Securities Exchange Act of 1934 (File No. -026450).

                  (b) Prior to the succession, the Registrant was a wholly owned
subsidiary  of Old Orion.  The  Registrant  was  organized  by Old Orion for the
purpose of  effecting  (i) a merger in which a wholly  owned  subsidiary  of the
Registrant was merged with and into Old Orion in a tax-free reorganization,  and
Old Orion became a wholly owned subsidiary of the Registrant (the "Merger"), and
(ii) an exchange of shares of the Registrant's Series C 6% Cumulative Redeemable
Convertible  Preferred Stock (the  "Registrant's  Series C Preferred Stock") for
limited partnership interests in International Private Satellite Partners, L.P.,
a Delaware limited partnership ("Orion Atlantic"),  held by each of the existing
limited partners of Orion Atlantic other than Old Orion (the "Exchange").

                  In the Merger,  each share of Old Orion's  common  stock,  par
value $.01 per share, Old Orion's Series A 8% Cumulative Redeemable  Convertible
Preferred  Stock and Series B 8%  Cumulative  Redeemable  Convertible  Preferred
Stock was converted,  without any action on the part of the holder thereof, into
the right to receive one share of the Registrant's  common stock, par value $.01
per share  (the  "Registrant's  Common  Stock"),  the  Registrant's  Series A 8%
Cumulative  Redeemable  Convertible  Preferred Stock (the "Registrant's Series A
Preferred Stock") and Series B 8% Cumulative  Redeemable  Convertible  Preferred
Stock (the  "Registrant's  Series B  Preferred  Stock,"  and  together  with the
Registrant's  Series A Preferred Stock,  the  "Registrant's  Preferred  Stock"),
respectively.

                  Following the Merger,  the  Registrant  has a  certificate  of
incorporation,   bylaws,  management  and  capital  structure  (other  than  the
Registrant's  Series C Preferred Stock issued in the Exchange  described  above)
substantially  identical  in all material  respects to those of Old Orion.  As a
result of the Merger,  (i) the Registrant  became a public holding  company that
owns all of the capital  stock of Old Orion,  which  continues  its business and
operations,  and (ii) the stockholders of Old Orion have  substantially the same
securities and rights in the Registrant that they had in Old Orion,  except that
their  percentage  ownership  in the  Registrant  is  diluted as a result of the
Exchange.

Item 3.        Securities to be Registered.

                  (a) Registrant's  Common Stock.  (i) 40,000,000  shares of the
Registrant's  Common  Stock are  presently  authorized  under  the  Registrant's
Restated Certificate of Incorporation, (ii) at the effective time of the Merger,
approximately  10,974,121 shares of the Registrant's Common Stock will be issued
and  outstanding,  none of  which  will be  held  by or for the  account  of the
Registrant either directly or by its subsidiaries.

                  (b) Registrant's  Preferred Stock. (i) 1,000,000 shares of the
Registrant's  Preferred Stock are presently  authorized  under the  Registrant's
Restated Certificate of Incorporation, (ii) at the effective time of the Merger,
approximately  13,871 shares of the  Registrant's  Series A Preferred  Stock and
4,298 shares of the Registrant's  Series B Preferred Stock will be issued,  none
of which are held by or for the account of the Registrant.

Item 4.        Description of Registrant's Securities to be Registered.

                  The  information  set forth under the caption  "Description of
Capital  Stock"  in  the  Registrant's   Registration   Statement  on  Form  S-4
(Registration No. 333-19795) is incorporated herein by reference.

Item 5.        Financial Statements and Exhibits.

                  (a) No financial statements need to be filed since the capital
structure and balance sheet of the Registrant  immediately  after the succession
were substantially the same as those of Old Orion.

                  (b)      Exhibits.

                  (i) The Agreement  and Plan of Merger,  dated January 8, 1997,

                SIXTH:  The authorized  number of directors of this  corporation
shall be not less than 3 and not more than 15.  The number of  directors  within
this range shall be stated in the  Corporation's  Bylaws, as may be amended from
time to time.  When the number of  directors  is changed the Board of  Directors
shall determine the class or classes to which the increased or decreased  number
of directors  shall be  apportioned;  provided  that the directors in each class
shall be as nearly  equal in number as  possible.  No  decrease in the number of
directors  shall  have  the  effect  of  shortening  the  term of any  incumbent
director.

                The Board of  Directors  shall be divided  into  three  classes,
designated  as Class I, Class II, and Class  III,  as nearly  equal in number as
possible,  and the term of office of directors of one class shall expire at each
annual meeting of stockholders, and in all cases until their successors shall be
elected and shall  qualify,  or until their  earlier  resignation,  removal from
office, death or incapacity.  The initial term of office of Class I shall expire
at the annual meeting of  stockholders in 1997, that of Class II shall expire at
the  annual  meeting in 1998,  and that of Class III shall  expire at the annual
meeting in 1999, and in all cases as to each director until his successor  shall
be elected and shall  qualify,  or until his earlier  resignation,  removal from
office, death or incapacity.

                Subject to the foregoing, at each annual meeting of stockholders
the  successors to the class of directors  whose term shall then expire shall be
elected  to hold  office  for a term  expiring  at the third  succeeding  annual
meeting and until their successors shall be elected and qualified.

                The directors  remaining in office acting by a majority vote, or
a sole remaining  director,  although less than a quorum,  are hereby  expressly
delegated  the power to fill any  vacancies in the Board of  Directors,  however
occurring,   whether  by  an  increase  in  the  number  of  directors,   death,
resignation, retirement,

<PAGE>



disqualification,  removal from office or otherwise,  and any director so chosen
shall hold office until the next  election of the class for which such  director
shall have been  chosen and until his  successor  shall  have been  elected  and
qualified,  or until his  earlier  resignation,  removal  from  office  death or
incapacity.

                SEVENTH:  In  furtherance  and not in  limitation  of the powers
conferred  by the laws of the State of  Delaware,  the Board of Directors of the
Corporation  is expressly  authorized  and empowered to adopt,  amend and repeal
bylaws of the Corporation.

                EIGHTH:  No director of the  Corporation  shall be liable to the
Corporation  or its  stockholders  for monetary  damages for breach or fiduciary
duty as a director, provided that nothing contained in this Article EIGHTH shall
eliminate  or limit  the  liability  of a  director  (i) for any  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)  under  Section 174 of the  Delaware  General
Corporation  Law, or (iv) for any transaction from which the director derived an
improper personal benefit.

                NINTH:  The Corporation  reserves the right at any time and from
time to time, to amend,  alter, change or repeal any provision contained in this
Certificate of Incorporation and other provisions  authorized by the laws of the
State of Delaware at the time in force may be added or  inserted,  in the manner
now or hereafter  prescribed by law, except that Articles FOURTH,  SIXTH, TENTH,
ELEVENTH,  TWELFTH,  THIRTEENTH,  FOURTEENTH  and this Article  NINTH may not be
altered,  amended,  or  repealed  except  by the  affirmative  vote of at  least
two-thirds (2/3) of the shares entitled to vote thereon and the affirmative vote
of the  Board of  Directors;  and all  rights,  preferences  and  privileges  of
whatsoever  nature conferred upon  stockholders,  directors or any other persons
whomsoever by and pursuant to this  Certificate of  Incorporation in its present
form or as hereafter  amended are granted subject to the rights reserved in this
Article NINTH.

                TENTH:  Notwithstanding  any other provision of this Amended and
Restated  Certificate of  Incorporation to the contrary,  outstanding  shares of
stock  of  the  Corporation  shall  always  be  subject  to  redemption  by  the
Corporation,  by action of the Board of  Directors,  if in the  judgment  of the
Board of Directors  such action should be taken,  pursuant to Section  151(b) of
the Delaware General  Corporation Law or any other applicable  provision of law,
to the extent  necessary to prevent the loss or secure the  reinstatement of any
license or franchise from any governmental agency held by the Corporation or any
of its subsidiaries to conduct any portion of the business of the Corporation or
any of its subsidiaries,  which license or franchise is conditioned upon some or
all  of  the  holders  of  the   Corporation's   stock   possessing   prescribed
qualifications. The terms and conditions of such redemption shall be as follows:


<PAGE>



                  (a) the redemption price of the shares to be redeemed pursuant
                to this  Article  TENTH  shall  be  determined  by the  Board of
                Directors  and shall be at least  equal to the lesser of (i) the
                Redemption  Value or (ii) if such  stock was  purchased  by such
                Disqualified  Holders  within one year of the  Redemption  Date,
                such Disqualified Holder's purchase price for such shares;

                   (b) the redemption  price of such shares may be paid in cash,
                Redemption Securities or any combination thereof;

                  (c) if less than all the shares held by  Disqualified  Holders
                are to be redeemed,  the shares to be redeemed shall be selected
                in such manner as shall be determined by the Board of Directors,
                which may include selection first of the most recently purchased
                shares  thereof,  selection  by lot or  selection  in any  other
                manner determined by the Board of Directors;

                  (d) at least 30 days' written  notice of the  Redemption  Date
                shall be given to the record  holders of the shares  selected to
                be  redeemed  (unless  waived in  writing  by any such  holder),
                provided  that  the  Redemption  Date  may be the  date on which
                written  notice shall be given to record  holders if the cash or
                Redemption  Securities  necessary to effect the redemption shall
                have been  deposited  in trust for the  benefit  of such  record
                holders  and  subject  to  immediate  withdrawal  by  them  upon
                surrender  of the  stock  certificates  of  their  shares  to be
                redeemed;

                  (e) from and after the Redemption  Date, any and all rights of
                whatever  nature  which  may be held  by the  owners  of  shares
                selected for redemption (including without limitation any rights
                to vote or  participate  in  dividends  declared on stock of the
                same class or series as such shares)  shall cease and  terminate
                and such owners shall  thenceforth  be entitled  only to receive
                the cash or Redemption Securities payable upon redemption; and

                   (f) such other terms and conditions as the Board of Directors
                shall determine.

                For purposes of this Article TENTH:

                                  (i)  "Disqualified   Holder"  shall  mean  any
                         holder  of  shares  of stock of the  Corporation  whose

                         taken  together  with the holding of shares of stock of
                         the  Corporation by any other holders,  may result,  in
                         the judgment of the Board of Directors, in the loss of,
                         or the  failure  to secure  the  reinstatement  of, any
                         license or franchise from any

<PAGE>



                         governmental  agency held by the  Corporation on any of
                         its subsidiaries to conduct any portion of the business
                         of the Corporation or any of its subsidiaries.

                                  (ii)  "Redemption  Value"  of a  share  of the
                         Corporation's  stock of any class or series  shall mean
                         the average  Closing Price for such a share for each of

                         the day on which  notice of  redemption  shall be given
                         pursuant  to  paragraph  (d)  of  this  Article  TENTH;
                         provided,  however,  that if  shares  of  stock of such
                         class  or  series  are  not  traded  on any  securities
                         exchange or in the over-the-counter market, "Redemption
                         Value" shall be determined by the Board of Directors in
                         good  faith.  "Closing  Price"  on any  day  means  the
                         reported  closing  sales price or, in case no such sale
                         takes place,  the average of the  reported  closing bid

                         Dealers, Inc. Automated Quotations System or any system
                         then in use,  or if no such  prices or  quotations  are
                         available, the fair market value on the day in question

                         Article TENTH.

                         debt or equity  securities of the  Corporation,  any of
                         its  subsidiaries  or  any  other  corporation,  or any
                         combination  thereof,  having such terms and conditions
                         (including,  without  limitation,  in the  case of debt
                         securities,  repayment  over a period  of up to  thirty
                         years,  or a longer period) as shall be approved by the
                         Board of Directors and which, together with any cash to
                         be paid as part of the redemption price, in the opinion

                         which provides other investment  banking,  brokerage or
                         other services to the Corporation), has a value, at the
                         time  notice  of  redemption   is  given   pursuant  to
                         paragraph  (d) of this  Article,  at least equal to the
                         price  required to be paid pursuant to paragraph (a) of
                         this Article TENTH (assuming, in the case of Redemption
                         Securities to be publicly traded, such

<PAGE>



                         Redemption   Securities  were  fully   distributed  and
                         subject only to normal trading activity).

                ELEVENTH:  Control Share Acquisitions

                A. Control Shares.  As used in this Article  ELEVENTH,  "control
share"  means shares of the  Corporation  that would have voting power that when
added to all the other shares of the Corporation owned by a person or in respect
to which that person may exercise or direct the exercise of voting power,  would
entitle that person,  immediately  after  acquisition of the shares (directly or
indirectly,  alone or as part of a group), to exercise or direct the exercise of
the voting power of the  Corporation in the election of directors  within any of
the following ranges of voting power:

                   (1)  One-fifth  or more but less  that a third of all  voting
                power.

                   (2)  One-third or more but less than a majority of all voting
                power.

                   (3) A majority or more of all voting power.


                B.       Control Share Acquisition.

                  1.  As  used  in  this  Article   ELEVENTH,   "control   share
acquisition"  means the  acquisition  (directly or  indirectly) by any person of
ownership  of, or the power to direct the  exercise of voting power with respect
to, issued and outstanding control shares.

                  2. For  purposes of this  Article  ELEVENTH,  shares  acquired
within ninety (90) days or shares acquired  pursuant to a plan to make a control
share acquisition are considered to have been acquired in the same acquisition.

                  3.  For  purposes  of this  Article  ELEVENTH,  a  person  who
acquires  shares in the ordinary course of business for the benefit of others in
good faith and not for the purpose of  circumventing  this Article  ELEVENTH has
voting  power only of shares in respect  of which that  person  would be able to
exercise or direct the vote without further instruction from others.

                  4. The acquisition of any shares of the  Corporation  does not
constitute a control share  acquisition if the acquisition is consummated in any
of the following circumstances:

                                  (1)      Before April 1, 1992.


<PAGE>



                (2)  Pursuant to a binding  contract  existing  before  April 1,
           1992.

                (3) Pursuant to the laws of descent and distribution.

                (4) Pursuant to the  satisfaction  of a pledge or other security
           interest   created  in  good  faith  and  not  for  the   purpose  of
           circumventing this Article ELEVENTH.

                (5)  Pursuant  to a  merger  or plan of  share  exchange  if the
           Corporation  is a party to the  agreement  of merger or plan of share
           exchange.

                (6) Pursuant to a tender or exchange offer that is made pursuant
           to an agreement to which the Corporation is a party.

                (7)  Directly  from the  Corporation,  or from any of its wholly
           owned subsidiaries.


                  5. The  acquisition  of any shares of the  Corporation in good
faith and not for the purpose of circumventing  this Article ELEVENTH by or from
(1)  any  person  whose  voting  rights  had  previously   been   authorized  by
stockholders in compliance with this Article  ELEVENTH,  or (2) any person whose
previous  acquisition  of shares of the  Corporation  would have  constituted  a
control share acquisition but for the  circumstances  specified in the paragraph
above, does not constitute a control share  acquisition,  unless the acquisition
entitles the person  (directly or indirectly,  alone or as a part of a group) to
exercise  or direct  the  exercise  of voting  power of the  Corporation  in the
election of directors in excess of the voting power otherwise authorized.

                C.  Interested   Shares.  As  used  in  this  Article  ELEVENTH,
"interested  shares" mean the shares of the  Corporation in respect of which any
of the following persons may exercise or direct the exercise of the voting power
of the Corporation in the election of directors:

                  (1) An acquiring person or member of a group with respect to a
control share acquisition.

                  (2) Any officer of the Corporation.

                  (3) Any employee of the Corporation  who is also a director of
the Corporation.



<PAGE>



                D. Acquiring Person  Statement.  Any person who proposes to make
or has made a control share  acquisition may at the person's election deliver an
acquiring  person  statement to the Corporation at the  Corporation's  principal
office. The acquiring person statement must set forth all of the following:

                  (1) The identity of the acquiring person and each other member
                of any  group of which  the  person  is a part for  purposes  of
                determining control shares.

                  (2) A statement that the acquiring  person  statement is given
                pursuant to this Article ELEVENTH.

                  (3) The number of shares of the Corporation owned (directly or

of  an  acquiring   person  statement  and  gives  an  undertaking  to  pay  the
Corporation's  expenses of a special  meeting,  within ten (10) days thereafter,
the  directors  of  the  Corporation   shall  call  a  special  meeting  of  the

to be  accorded to the shares  acquired  or to be acquired in the control  share
acquisition.

                  2. Unless the  acquiring  person  agrees in writing to another

                  3. If no request is made, the voting rights to be accorded the

special or annual meeting of stockholders.

                  4. If the acquiring  person so requests in writing at the time

                F. Notice.

                  1. If a special  meeting is  requested,  notice of the special
meeting of stockholders shall be given as promptly as reasonably  practicable by
the Corporation to all  stockholders of record as of the record date set for the
meeting, whether or not entitled to vote at the meeting.

                  2.  Notice of the  special  or annual  stockholder  meeting at
which the voting rights are to be considered  must include or be  accompanied by
both of the following:

                         (1) a copy of the acquiring person statement  delivered
                    to the Corporation pursuant to this Article ELEVENTH.

                    no  recommendation,  with  respect to the  proposed  control
                    share acquisition.


                G. Voting Rights.

                  1. Control shares acquired in a control share acquisition have
the same voting  rights as were  accorded  the shares  before the control  share
acquisition  only  to  the  extent  granted  by  resolutions   approved  by  the
stockholders of the Corporation.

                  2. To be adopted under this section,  the resolutions shall be
approved  by a majority  of all the votes  which  could be cast in a vote on the
election  of  directors  by all the  outstanding  shares  other than  interested
shares.  Interested  shares shall not be entitled to vote on the matter,  and in
determining whether a quorum exists, all interested shares shall be disregarded.
For the purpose of this subsection,  the interested share shall be determined as
of the record  date for  determining  the  stockholders  entitled to vote at the
meeting.

                H. Redemption.

                  1. Control shares acquired in a control share acquisition with
respect  to  which  no  acquiring  person  statement  has  been  filed  with the
Corporation  may, at any time during the period ending sixty (60) days after the
last  acquisition  of  control  shares by the  acquiring  person,  be subject to
redemption by the  Corporation at the redemption  price specified in paragraph 3
of this subsection.

                  2. Control shares acquired in a control share  acquisition are
not subject to  redemption  after an acquiring  person  statement has been filed
unless the shares are not accorded  full voting  rights by the  stockholders  as
provided above.

                  3. The  redemption  price for shares to be redeemed under this
section  shall be the number of such  shares  multiplied  by the  dollar  amount
(rounded to the nearest  cent) equal to the average per share  price,  including
any brokerage commissions,  transfer taxes and soliciting dealer's fees, paid by
the acquiring person for such shares.  The Corporation may rely  conclusively on
public  announcements by, or filings with the Securities and Exchange Commission
by, the acquiring person as to the prices so paid.

                I. Dissenters Rights.

                  1. In the event  control  shares  acquired in a control  share
acquisition  are  accorded  full  voting  rights  and the  acquiring  person has
acquired  control  shares  with a  majority  or more of all  voting  power,  all
shareholders of the Corporation, other than the acquiring person, have the right
to dissent from the granting of voting rights and to demand  payment of the fair
value of their shares under Section 262 of the Delaware General  Corporation Law
as though such  granting of voting rights were a corporate  action  described in
paragraph (b) of Section 262,  except that the  provisions of subsection  (1) of
paragraph (b) of Section 262 shall not be applicable.

                  2. For purposes of this  section  "fair value" of shares under
Section 262 of the Delaware  General  Corporation  Law shall in no event be less
than the  highest  price per share paid in the  control  share  acquisition,  as
adjusted for any subsequent  stock  dividends or reverse stock splits or similar
changes.

                                           (ii) the  right to vote  pursuant  to
                                           any    agreement,    arrangement   or

                                           any    agreement,    arrangement   or
                                           understanding   for  the  purpose  of
                                           acquiring,    holding,    voting   or

                                  understanding,  or upon exercise of conversion
                                  rights, warrants or options, or otherwise.

                                  Corporation;  provided,  however, that for the
                                  purposes  of  the   definition  of  Interested
                                  Stockholder  set forth in  paragraph 2 of this
                                  subsection C, the term

                                  which a  majority  of  each  class  of  equity

                                  the  Corporation  prior to the  time  that the

                                           is  listed,  or, if such stock is not
                                           listed  on  any  such  exchange,  the
                                           highest  closing bid  quotation  with
                                           respect  to a  share  of  such  stock
                                           during  the 30-day  period  preceding
                                           the date in question on the  National

                                           any system then in use, or if no such

                D.       Powers of the Board of  Directors.  A  majority  of the
                         directors of the  Corporation  shall have the power and
                         duty to  determine  for the  purposes  of this  Article
                         TWELFTH,  on the  basis  of  information  known to them
                         after  reasonable  inquiry,  (1) whether a person is an
                         Interested  Stockholder,  (2) the  number  of shares of
                         Voting  Stock  beneficially  owned by any  person,  (3)

<PAGE>



                         person is an Affiliate or Associate of another, and (4)
                         whether  the  assets  which  are  the  subject  of  any
                         Business  Combination  have, or the consideration to be
                         received for the issuance or transfer of  securities by
                         the  Corporation  or any  Subsidiary  in  any  Business
                         Combination  has an  aggregate  Fair  Market  Value  of
                         $1,000,000 or more.

                E.       No  Effect  on  Fiduciary   Obligations  of  Interested
                         Stockholders. Nothing contained in this Article TWELFTH
                         shall  be   construed   to   relieve   any   Interested
                         Stockholder  from any fiduciary  obligation  imposed by
                         law.

                THIRTEENTH:  Indemnification.

                A. Authorization of Indemnification. Each person who was or is a
party or is threatened  to be made a party to or is involved in any  threatened,
pending or  completed  action,  suit or  proceeding,  whether  civil,  criminal,
administrative  or  investigative  and  whether  by  or  in  the  right  of  the
corporation or otherwise (a "proceeding"), by reason of the fact that he or she,
or a person of whom he or she is the legal representative,  is or was a director
or  officer  of the  corporation  or is or was  serving  at the  request  of the
corporation as a director,  officer, employee or agent of another corporation or
of a partnership,  joint venture,  trust or other enterprise,  including service
with respect to an employee  benefit plan, shall be (and shall be deemed to have
a contractual right to be) indemnified and held harmless by the corporation (and
any successor to the  corporation  by merger or otherwise) to the fullest extent
authorized  by, and subject to the  conditions  and (except as provided  herein)
procedures set forth in the Delaware General Corporation Law, as the same exists
or may hereafter be amended (but any such amendment shall not be deemed to limit
or prohibit the rights of  indemnification  hereunder for past acts or omissions
of  any  such  person  insofar  as  such  amendment   limits  or  prohibits  the
indemnification  rights that said law permitted the corporation to provide prior
to such  amendment),  against all expenses,  liabilities  and losses  (including
attorney's fees, judgments,  fines, ERISA taxes or penalties and amounts paid or
to be paid in  settlement)  reasonably  incurred  or  suffered by such person in
connection  therewith;  provided,  however, that the corporation shall indemnify
any such person seeking indemnification in connection with a proceeding (or part
thereof)  initiated  by such  person  (except  for a suit or action  pursuant to
subsection B only if such  proceeding  (or part  thereof) was  authorized by the
board of directors of the corporation. Persons who are not directors or officers
of the  corporation  may be similarly  indemnified in respect of such service to
the extent  authorized at any time by the board of directors of the corporation.
The indemnification  conferred in this subsection A also shall include the right
to be paid by the  corporation  (and such  successor)  the  expenses  (including
attorney's  fees)  incurred in the defense of or other  involvement  in any such
proceeding  in  advance  of its final  disposition  (including  in the case of a
director or former director expenses of separate legal

<PAGE>



counsel, up to a maximum of $50,000,  but only in the event that the director or
former  director as the indemnified  party  reasonably  determines,  assuming an
outcome  unfavorable  to such  indemnified  party,  that  there is a  reasonable
probability  that such  proceeding  may  materially  and  adversely  affect such
indemnified  party,  or that  there  may be  legal  defenses  available  to such
indemnified  party that are different from or in addition to those  available to
the  corporation);  provided,  however,  that, if and to the extent the Delaware
General  Corporation  Law  requires,  the  payment of such  expenses  (including
attorney's  fees)  incurred  by a  director  or  officer in advance of the final
disposition of a proceeding  shall be made only upon delivery to the corporation
of an  undertaking  by or on behalf of such  director  or  officer  to repay all
amounts  so paid in  advance  if it shall  ultimately  be  determined  that such
director or officer is not entitled to be indemnified under this subsection A or
otherwise; and provided further, that, such expenses incurred by other employees
and agents may be so paid in advance upon such terms and conditions,  if any, as
the board of directors deems appropriate.

                B. Right of Claimant to Bring Action against the Corporation. If
a  claim  under  subsection  A of  this  section  is not  paid  in  full  by the
corporation  within  sixty days after a written  claim has been  received by the
corporation, the claimant may at any time thereafter bring an action against the
corporation  to recover  the unpaid  amount of the claim and, if  successful  in
whole or in part, the claimant shall be entitled to be paid also the expenses of
prosecuting such action. It shall be a defense to any such action (other than an
action brought to enforce a claim for expenses  incurred in connection  with any
proceeding in advance of its final disposition  where the required  undertaking,
if any is required,  has been tendered to the corporation) that the claimant has
not met the  standards of conduct which make it  permissible  under the Delaware
General  Corporation  Law for the  corporation to indemnify the claimant for the
amount claimed or is otherwise not entitled to indemnification  under subsection
A of this  section  but the  burden  of  proving  such  defense  shall be on the
corporation.  The failure of the  corporation  (in the manner provided under the
Delaware General Corporation Law) to have made a determination prior to or after
the commencement of such action that  indemnification  of the claimant is proper
in the  circumstances  because  he or she  has met the  applicable  standard  of
conduct set forth in the Delaware General Corporation Law shall not be a defense
to the  action  or  create  a  presumption  that  the  claimant  has not met the
applicable standard of conduct.  An actual  determination by the corporation (in
the  manner  provided  under the  Delaware  General  Corporation  Law) after the
commencement  of such  action  that the  claimant  has not met  such  applicable
standard  of conduct  shall not be a defense to the action,  but shall  create a
presumption that the claimant has not met the applicable standard of conduct.

                C.  Non-exclusivity.  The rights to indemnification  and advance
payment of expenses provided by subsection A of this section shall not be deemed
exclusive of any other rights to which those seeking indemnification and advance

<PAGE>



payment  of  expenses  may be  entitled  under  any  bylaw,  agreement,  vote of
stockholders or disinterested  directors or otherwise,  both as to action in his
or her official capacity and as to action in another capacity while holding such
office.

                D. Survival of Indemnification.  The indemnification and advance
payment of expenses  and rights  thereto  provided  by, or granted  pursuant to,
subsection A of this section shall, unless otherwise provided when authorized or
ratified,  continue  as to a person  who has ceased to be a  director,  officer,
employee   or  agent  and  shall   inure  to  the   benefit   of  the   personal
representatives, heirs, executors and administrators of such person.

                E. Insurance.  The corporation  shall have power to purchase and
maintain  insurance  on behalf of any person who is or was a director,  officer,
employee or agent of the corporation, or is or was serving at the request of the
corporation as a director,  officer, employee or agent of another corporation or
of a  partnership,  joint  venture,  trust  or  other  enterprise,  against  any
liability  asserted  against  such person or incurred by such person in any such
capacity,  or arising out of such person's status as such, and related expenses,
whether or not the  corporation  would have the power to  indemnify  such person
against such liability under the provisions of the Delaware General  Corporation
Law.

duly executed  waiver of notice  thereof,  at which  stockholders  shall elect a
board of directors and transact  such other  business as may properly be brought
before the meeting.

                2.3 Special Meetings. Special meetings of the stockholders,  for
any  purpose  or  purposes,  unless  otherwise  prescribed  by statute or by the
certificate of incorporation,  may be called by the board of directors or by the
president,  and shall be called by the  president or secretary at the request in
writing of two or more stockholders  owning at least 35% in amount of the entire
capital stock of the corporation  issued and outstanding and entitled to vote if
no special  meeting of  stockholders  has been called and held at the request of
stockholders within the six months preceding such written request.  Such request
shall include a statement of the purpose or purposes of the proposed meeting.

                2.4 Notice of Meetings.  Written  notice of the annual  meeting,
stating  the  place,  date  and  hour of the  meeting,  shall  be  given to each
stockholder  entitled  to vote at such  meeting  not less than ten nor more than
sixty days before the date of the meeting.  Written notice of a special  meeting
of stockholders, stating the place, date and hour of the meeting and the purpose
or purposes for which the meeting is called,  shall be given to each stockholder
entitled  to vote at such  meeting  not less than ten nor more than  sixty  days
before the date of the meeting.

                2.5 Business at Special  Meetings.  Business  transacted  at any
special meeting of  stockholders  shall be limited to the purposes stated in the
notice.

                2.6 List of  Stockholders.  The  officer  who has  charge of the
stock ledger of the corporation shall prepare and make, at least ten days before
every meeting of stockholders,  a complete list of the stockholders  entitled to
vote at the meeting,  arranged in alphabetical  order and showing the address of
each

<PAGE>



stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any  stockholder,  for any purpose
germane to the meeting, during ordinary business hours, for a period of at least
ten days  prior to the  meeting,  either at a place  within  the city  where the
meeting  is to be held,  which  place  shall be  specified  in the notice of the
meeting, or, if not so specified,  at the place where the meeting is to be held.
The list shall also be  produced  and kept at the time and place of the  meeting
during the whole time thereof,  and may be inspected by any  stockholder  who is
present.  The  stock  ledger  shall  be the  only  evidence  as to who  are  the
stockholders  entitled to examine the stock  ledger,  the list  required by this
section or the books of the corporation, or to vote in person or by proxy at any
meeting of stockholders.

                2.7 Quorum at Meetings.  Except as otherwise provided by statute
or by the certificate of  incorporation,  the holders of a majority of the stock
issued  and  outstanding  and  entitled  to vote  thereat,  present in person or
represented  by  proxy,  shall  constitute  a  quorum  at  all  meetings  of the
stockholders for the transaction of business. If, however, such quorum shall not
be  present  or  represented  at  any  such  meeting  of the  stockholders,  the
stockholders  entitled  to vote  thereat,  present in person or  represented  by
proxy, shall have power to adjourn the meeting from time to time to another time
and place,  without notice other than  announcement at the meeting of such other
time and place.  At the adjourned  meeting at which a quorum shall be present or
represented,  any business may be transacted which might have been transacted at
the original  meeting.  If the  adjournment  is for more than thirty days, or if
after the  adjournment a new record date is fixed for the adjourned  meeting,  a
notice of the  adjourned  meeting shall be given to each  stockholder  of record
entitled to vote at the meeting.

<PAGE>



                2.8  Voting  and  Proxies.  Unless  otherwise  provided  in  the
certificate  of  incorporation,  and subject to the provisions of Section 6.4 of
these Bylaws,  each stockholder shall be entitled to one vote on each matter, in
person or by proxy,  for each share of the  corporation's  capital  stock having
voting power which is held by such stockholder. No proxy shall be voted or acted
upon after three  years from its date,  unless the proxy  provides  for a longer
period.  A duly  executed  proxy  shall be  irrevocable  if it states that it is
irrevocable  and if,  and  only as  long  as,  it is  coupled  with an  interest
sufficient  in  law to  support  an  irrevocable  power.  A  proxy  may be  made
irrevocable  regardless  of whether the interest  with which it is coupled is an
interest in the stock itself or an interest in the corporation generally.

                2.9  Required  Vote.  When a quorum is present at any meeting of
stockholders,  all matters shall be determined, adopted and approved by the vote
(which need not be by ballot) of the  holders of a majority of the stock  having
voting power,  present in person or  represented  by proxy,  unless the proposed
action is one upon which, by express provision of statutes or of the certificate
of incorporation, a different vote is specified and required, in which case such
express  provision  shall  govern and  control the  decision  of such  question.
Notwithstanding  the foregoing,  candidates for election as members of the board
of  directors  who  receive  the  highest  number of votes,  up to the number of
directors to be chosen,  shall stand  elected,  and an absolute  majority of the
votes cast shall not be a  prerequisite  to the election of any candidate to the
board of directors.

                2.10.  Stockholder  Actions. Any action required or permitted to
be taken by the stockholders must be effected at a duly called annual or special
meeting of such  stockholders  and may not be effected by any consent in writing
by such stockholders.

                2.11.  Nominating  Committee.  Only persons who are nominated in

Directors of the  corporation  may be made at a meeting of stockholders by or at
the direction of the Board of Directors or by any stockholder of the corporation
entitled to vote for the election of directors at the meeting who complies  with
the notice  procedures set forth in this Section 2.11. Such  nominations,  other
than those made by or at the direction of the Board of Directors,  shall be made

timely,  a stockholder's  notice shall be delivered to or mailed and received at
the principal  executive  offices of the  corporation  not less than 50 days nor
more than 90 days prior to the  meeting;  provided,  however,  that in the event
that less than 60 days'  notice or prior  public  disclosure  of the date of the
meeting is given or made to stockholders, notice by the stockholder to be timely
must be so  received  not  later  than  the  close of  business  on the 10th day
following  the day on which such notice of the date of the meeting was mailed or
such public disclosure was made. Such  stockholder's  notice shall set forth (a)
as to each person whom the  stockholder  proposes  to nominate  for  election or
re-election as a director,  (i) the name,  age,  business  address and residence
address of such person,  (ii) the  principal  occupation  or  employment of such
person,  (iii)  the class and  number  of  shares of the  corporation  which are
beneficially  owned by such person,  and (iv) any other information  relating to
such person that is required to be  disclosed  in  solicitations  of proxies for
election  of  directors,  or is  otherwise  required,  in each case  pursuant to
Regulation 14A under the Securities  Exchange Act of 1934, as amended (including
without  limitation  such person's  written  consent to being named in the proxy
statement as a nominee and to serving as a director if  elected);  and (b) as to
the  stockholder  giving the notice (i) the name and address,  as they appear on
the  corporation's  books, of such  stockholder and (ii) the class and number of
shares of the corporation which are beneficially  owned by such stockholder.  At
the request of the Board of Directors,

<PAGE>



 any person nominated by the Board of Directors for election as a director shall
furnish to the Secretary of the Corporation that information  required to be set
forth in a stockholder's  notice of nomination which pertains to the nominee. No
later  than the  tenth  day  following  the  date of  receipt  of a  stockholder
nomination  submitted  pursuant  to this  Section  2.11,  the  president  of the
corporation  shall,  if the facts  warrant,  determine and notify in writing the
stockholder  making  such  nomination  that  such  nomination  was  not  made in
accordance  with the time  limits  and/or  other  procedures  prescribed  by the
Bylaws.  If no such  notification  is mailed  to such  stockholder  within  such
ten-day period,  such nomination shall be deemed to have been made in accordance
with the  provisions  of this  Section  2.11.  No person  shall be eligible  for
election as a director of the  corporation  unless  nominated in accordance with
the procedures set forth in this Section 2.11.

                2.12.  Business at Annual  Meeting.  At an annual meeting of the
stockholders,  only such business shall be conducted as shall have been properly
brought before the meeting.  To be properly  brought  before an annual  meeting,
business  must be (a)  specified  in the  notice of meeting  (or any  supplement
thereto)  given by or at the direction of the Board of Directors,  (b) otherwise
properly  brought  before  the  meeting by or at the  direction  of the Board of
Directors,   or  (c)  otherwise   properly  brought  before  the  meeting  by  a
stockholder.  For business to be properly  brought before an annual meeting by a
stockholder, the stockholder must have given timely notice thereof in writing to
the Secretary of the Corporation.  To be timely, a stockholder's  notice must be
delivered to or mailed and received at the  principal  executive  offices of the
corporation  not less than 50 days nor more than 90 days  prior to the  meeting;
provided,  however,  that in the event  that less than 60 days'  notice or prior
public  disclosure of the date of the meeting is given or made to  stockholders,
notice by the  stockholder  to be timely must be so received  not later than the
close of business on the 10th day following

<PAGE>



the day on which  such  notice of the date of the annual  meeting  was mailed or
such public  disclosure was made. A stockholder's  notice to the Secretary shall

meeting (a) a brief description of the business desired to be brought before the
annual  meeting  and the  reasons  for  conducting  such  business at the annual
meeting, (b) the name and address, as they appear on the corporation's books, of
the stockholder  proposing such business,  (c) the class and number of shares of
the corporation  which are beneficially  owned by the  stockholder,  and (d) any

Section 2.12,  the president of the  corporation  shall,  if the facts  warrant,
determine and notify in writing the stockholder submitting such notice that such
notice was not made in accordance  with the time limits and/or other  procedures
prescribed by the Bylaws.  If no such notification is mailed to such shareholder
within such  ten-day  period,  such  stockholder  notice  containing a matter of
business shall be deemed to have been made in accordance  with the provisions of
this Section 2.12.  Notwithstanding anything in these Bylaws to the contrary, no
business shall be conducted at an annual  meeting except in accordance  with the
procedures set forth in this Section 2.12.

3.      Directors.

                3.1 Powers. The business and affairs of the corporation shall be
managed by or under the direction of the board of directors,  which may exercise
all such powers of the corporation and do all such lawful acts and things as are
not by  statute  or by the  certificate  of  incorporation  or by  these  Bylaws
directed or required to be exercised or done by the stockholders.

<PAGE>



                3.2.  Number and Election.  The number of directors  which shall

may hold meetings,  both regular and special, either within or without the State
of Delaware.

                3.5 First Meeting of Each Board. The first meeting of each newly
elected  board of  directors  shall be held at such  time and  place as shall be
specified in a notice given as hereinafter  provided for special meetings of the
board of  directors,  or as shall be  specified  in a  written  waiver of notice
signed by all of the directors.

                3.6 Regular Meetings. Regular meetings of the board of directors
may be held without  notice at such time and at such place as shall from time to
time be determined by the board of directors.

                3.7  Special  Meetings.  Special  meetings  of the  board may be
called by the president on one day's notice to each director,  either personally

of one-third of the total number of directors.

                3.8 Quorum and Vote at  Meetings.  At all meetings of the board,
one director if a board of one director is authorized, or such greater number of
directors as is not less than a majority of the total number of directors, shall
constitute a

<PAGE>



quorum for the transaction of business.  The vote of a majority of the directors
present at any meeting at which there is a quorum  shall be the act of the board
of directors,  except as may be otherwise specifically provided by statute or by
the  certificate  of  incorporation.  If a quorum  shall not be  present  at any
meeting of the board of directors, the directors present thereat may adjourn the
meeting to another time and place, without notice other than announcement at the
meeting of such other time and place.

                3.9 Telephone Meetings. Members of the board of directors or any
committee  designated by the board may participate in a meeting of such board or
committee by means of conference telephone or similar  communications  equipment
by means of which all persons  participating in the meeting can hear each other,
and  participation  in a  meeting  pursuant  to this  section  shall  constitute
presence in person at such meeting.

                3.10 Action Without Meeting.  Unless otherwise restricted by the
certificate of incorporation  or these Bylaws,  any action required or permitted
to be taken at any meeting of the board of directors or of any committee thereof
may be taken without a meeting, if all members of the board or committee, as the
case may be, consent  thereto in writing,  and the writing or writings are filed
with the minutes of proceedings of the board of directors or committee.

                3.11  Committees  of  Directors.  The board of directors  may by
resolution  passed by a  majority  of the  whole  board,  designate  one or more
committees,  each  committee  to consist of one or more of the  directors of the
corporation.  The board may designate one or more directors as alternate members
of any  committee,  who may  replace  any absent or  disqualified  member at any
meeting of the  committee.  If a member of a committee  shall be absent from any
meeting,  or disqualified  from voting thereat,  the remaining member or members
present and not disqualified from voting, whether or not such member or members

<PAGE>



constitute a quorum, may, by unanimous vote, appoint another member of the board
of directors  to act at the meeting in the place of such absent or  disqualified
member.  Any such  committee,  to the extent  provided in the  resolution of the
board of directors,  shall have and may exercise all the powers and authority of
the board of  directors  in the  management  of the  business and affairs of the
corporation,  and may authorize the seal of the corporation to be affixed to all
papers  which may  require  it;  but no such  committee  shall have the power or
authority in reference to amending the certificate of incorporation (except that
a committee  may, to the extent  authorized  in the  resolution  or  resolutions
providing  for the issuance of shares of stock adopted by the board of directors
pursuant  to  Section  151(a)  of the  General  Corporation  Law of the State of
Delaware  (hereinafter the "GCL"),  fix any of the preferences or rights of such
shares  relating to dividends,  redemption,  dissolution,  any  distribution  of
assets of the corporation or the conversion into, or the exchange of such shares
for, shares of any other class or classes or any other series of the same or any
other class or classes of stock of the  corporation),  adopting an  agreement of
merger or consolidation pursuant to Sections 251 or 252 of the GCL, recommending
to the stockholders  the sale, lease or exchange of all or substantially  all of
the  corporation's  property  and assets,  recommending  to the  stockholders  a
dissolution of the corporation or a revocation of a dissolution, or amending the
Bylaws of the  corporation;  and,  unless  otherwise  expressly  provided in the
resolution,  no such  committee  shall have the power or  authority to declare a
dividend,  to authorize  the  issuance of stock,  or to adopt a  certificate  of
ownership  and merger  pursuant to Section  253 of the GCL.  Such  committee  or
committees  shall have such name or names as may be determined from time to time
by resolution adopted by the board of directors.  Unless otherwise  specified in
the  resolution  of the board of directors  designating  the  committee,  at all
meetings of each such committee of directors, a majority of the

<PAGE>



total  number of  members of the  committee  shall  constitute  a quorum for the
transaction  of  business,  and the vote of a  majority  of the  members  of the
committee  present at any meeting at which there is a quorum shall be the act of
the  committee.  Each committee  shall keep regular  minutes of its meetings and
report the same to the board of directors, when required.

                3.12 Compensation of Directors.  Unless otherwise  restricted by
the  certificate  of  incorporation,  the  board  of  directors  shall  have the
authority to fix the compensation of directors.  The directors may be paid their
expenses,  if any, of  attendance  at each meeting of the board of directors and
may be paid a fixed sum for attendance at each meeting of the board of directors
or a stated salary as director. No such payment shall preclude any director from
serving  the  corporation  in any  other  capacity  and  receiving  compensation
therefor.   Members  of  special  or  standing   committees  may  be  paid  like
compensation for attending committee meetings.

4.      Notices of Meetings.

                4.1 Notice Procedure.  Whenever, whether under the provisions of
any statute or of the certificate of incorporation or of these Bylaws, notice is
required to be given to any director or stockholder,  such requirement shall not
be construed to require the giving of personal notice.  Such notice may be given
in writing, by mail,  addressed to such director or stockholder,  at his address
as it appears on the records of the  corporation,  with postage thereon prepaid,
and such  notice  shall  be  deemed  to be  given  at the time  when the same is
deposited in the United  States mail.  Notice to directors  may also be given by
telex, telegram or telephone.

                4.2  Waivers  of  Notice.  Whenever  the giving of any notice is
required by statute,  the certificate of incorporation or these Bylaws, a waiver
thereof, in

<PAGE>



writing, signed by the person or persons entitled to said notice, whether before
or  after  the  event as to which  such  notice  is  required,  shall be  deemed
equivalent to notice.  Attendance  of a person at a meeting  shall  constitute a
waiver of notice of such meeting,  except when the person  attends a meeting for
the express  purpose of  objecting,  at the  beginning  of the  meeting,  to the
transaction  of any  business  because  the  meeting is not  lawfully  called or
convened.  Neither  the  business to be  transacted  at, nor the purpose of, any
regular  or  special  meeting  of the  stockholders,  directors  or members of a
committee of directors need be specified in any written waiver of notice, unless
so required by the certificate of incorporation, by statute or by these Bylaws.

secretaries and assistant treasurers, who shall exercise such powers and perform
such duties as shall be determined from time to time by the board. Any number of

majority of the board of directors.  Any vacancy  occurring in any office of the
corporation  shall be filled  by the board of  directors.  All  officers  of the

shall  have the  authority  to  execute  bonds,  mortgages  and other  contracts
requiring a seal,  under the seal of the  corporation,  except where required or
permitted  by law to be  otherwise  signed and  executed  and  except  where the
signing and  execution  thereof  shall be  expressly  delegated  by the board of
directors to some officer or agent of the corporation.

                5.8 Vice Chairman or Vice  Presidents.  If the  directors  shall
appoint one or more vice presidents, such vice chairman or vice presidents shall

the  corporation,  and the  secretary,  or an  assistant  secretary,  shall have
authority to affix the same to any instrument  requiring it, and when so affixed
it may be attested by the signature of the secretary or by the signature of such
assistant  secretary.  The board of directors may give general  authority to any
other officer to affix the seal of the corporation and to attest the affixing by
such  officer's  signature.  The  secretary or an assistant  secretary  may also
attest all instruments signed by the president or any vice president.

                5.10 Assistant Secretary.  The assistant secretary,  or if there
be more than one, the assistant secretaries in the order determined by the board
of  directors  (or if there shall have been no such  determination,  then in the
order of their election), shall, in the absence of the secretary or in the event
of the secretary's  inability or refusal to act, perform the duties and exercise
the powers of the  secretary,  and shall perform such other duties and have such

treasurer  shall give the corporation a bond in such sum and with such surety or
sureties as shall be  satisfactory  to the board of  directors  for the faithful
performance of the duties of the  treasurer's  office and for the restoration to
the corporation,  in case of the treasurer's death,  resignation,  retirement or
removal from office, of all books, papers, vouchers, money and other property of

                5.12 Assistant Treasurer.  The assistant treasurer,  or if there

event of the  treasurer's  inability  or refusal to act,  perform the duties and
exercise the powers of the  treasurer,  and shall  perform such other duties and

the corporation shall be represented by certificates, provided that the board of
directors may provide by resolution  or  resolutions  that some or all of any or
all classes or series of the corporation's stock shall be uncertificated shares.
Any such resolution shall not apply to shares represented by a certificate until
such certificate is surrendered to the corporation. Notwithstanding the adoption
of  such a  resolution  by  the  board  of  directors,  every  holder  of  stock
represented  by  certificates  and upon request  every holder of  uncertificated
shares shall be entitled to have a certificate  signed by, or in the name of the
corporation  by the president or vice  president,  and by the  treasurer  and/or
assistant  treasurer,  or  the  secretary  or an  assistant  secretary  of  such
corporation  representing the number of shares  registered in certificate  form.
Any or all the  signatures  on the  certificate  may be  facsimile.  In case any
officer,  transfer  agent or registrar  whose  signature or facsimile  signature
appears on a certificate shall have ceased to be such officer, transfer agent or
registrar before such certificate is issued, it may be issued by the corporation
with the same  effect as if such  person were such  officer,  transfer  agent or
registrar at the date of issue.

                6.2 Lost  Certificates.  The board of directors may direct a new
certificate or  certificates of stock or  uncertificated  shares to be issued in
place of any certificate or certificates  theretofore  issued by the corporation
and  alleged  to have been  lost,  stolen or  destroyed,  upon the  making of an
affidavit of that fact by the person  claiming that the certificate of stock has
been  lost,  stolen  or  destroyed.  When  authorizing  such  issuance  of a new
certificate or  certificates,  the board of directors may, in its discretion and
as a condition  precedent  to the  issuance  thereof,  require the owner of such
lost,  stolen or destroyed  certificate or  certificates,  or such owner's legal
representative,  to advertise the same in such manner as the board shall require
and/or to give the corporation a bond, in such

<PAGE>



 sum as the board may direct,  as  indemnity  against any claim that may be made
against the corporation on account of the certificate alleged to have been lost,
stolen or  destroyed or on account of the  issuance of such new  certificate  or
uncertificated shares.

                6.3  Transfers.  The  transfer  of stock and  certificates  that
represent the stock and the transfer of uncertificated  shares shall be effected
in accordance  with the laws of the State of Delaware.  Any  restriction  on the
transfer of a security imposed by the corporation  shall be noted  conspicuously
on the security.

                6.4  Fixing  Record  Date.  In order  that the  corporation  may
determine the stockholders  entitled to notice of, or to vote at, any meeting of
stockholders  or any  adjournment  thereof,  or to express  consent to corporate
action in  writing  without a meeting,  or  entitled  to receive  payment of any
dividend  or other  distribution  or  allotment  of any  rights,  or entitled to
exercise any rights in respect of any change, conversion or exchange of stock or
for the purpose of any other lawful  action,  the board of directors may fix, in
advance,  a record  date,  which  shall not be more than sixty nor less than ten
days  before  the date of such  meeting,  nor more than  sixty days prior to any
other action.  A determination  of stockholders of record entitled to notice of,
or to vote at, a meeting of  stockholders  shall apply to any adjournment of the
meeting;  provided,  however,  that the board of directors  may fix a new record
date for the adjourned meeting.

                6.5 Registered  Stockholders.  The corporation shall be entitled
to recognize  the  exclusive  right of a person  registered  on its books as the
owner of shares to receive dividends, to receive notifications,  to vote as such
owner,  and to  exercise  all  the  rights  and  powers  of an  owner;  and  the
corporation  shall not be bound to recognize  any equitable or other claim to or
interest in such share or shares on the part of any other person, whether or not
it shall have express or

<PAGE>



other notice thereof,  except as otherwise  provided by the laws of the State of
Delaware.

7.      Indemnification.

                Indemnification  of certain persons by the corporation  shall be
as specified in or determined  pursuant to the Certificate of  Incorporation  of
the Corporation as is in effect from time to time.

8.      General Provisions.

                8.1   Dividends.   Dividends  upon  the  capital  stock  of  the
corporation,  subject to the provisions of the certificate of incorporation  and
the laws of the State of Delaware,  may be declared by the board of directors at
any  regular  or  special  meeting.  Subject to the  provisions  of the  General
Corporation Law of the State of Delaware,  such dividends may be paid either out
of surplus,  as defined in the General Corporation Law of the State of Delaware,
or in the event that there shall be no such surplus,  out of the net profits for
the fiscal year in which the dividend is declared  and/or the  preceding  fiscal
year.  Dividends  may  be  paid  in  cash,  in  property,  or in  shares  of the
corporation's  capital  stock,  subject  to  the  provisions,  if  any,  of  the
certificate of incorporation.

                8.2 Reserves.  The directors of the  corporation  may set apart,
out of the funds of the  corporation  available  for  dividends,  a  reserve  or
reserves for any proper purpose and may abolish any such reserve.

                8.3  Execution of  Instruments.  All checks or demands for money
and notes of the corporation shall be signed by such officer or officers or such
other  person  or  persons  as the  board of  directors  may  from  time to time
designate.

                8.4 Fiscal  Year.  The fiscal year of the  corporation  shall be
fixed by resolution of the board of directors.

<PAGE>



                8.5 Seal. The corporate  seal shall have  inscribed  thereon the
name of the  corporation,  the year of its organization and the words "Corporate
Seal, Delaware". The seal may be used by causing it or a facsimile thereof to be
impressed or affixed or otherwise reproduced.

                Section 9. Amendments.  These Bylaws may be altered,  amended or
repealed and new bylaws may be adopted by a majority of the Board of  Directors,
except that Sections 2.3, 2.10,  2.11, 2.12, 3.2, 3.3 and this Section 9 may not
be altered,  amended,  or repealed except by at the affirmative vote of at least
two-thirds the shares  entitled to vote thereon or the  affirmative  vote of the
Board of Directors.

                        SERIES A 8% CUMULATIVE REDEEMABLE
                           CONVERTIBLE PREFERRED STOCK


                  The following sections set forth the designations,  rights and
preferences  of the  Corporation's  Series A Preferred.  Capitalized  terms used
herein are defined in Section 12 below.

                  Section 1.        Dividends.

                  1A.   General   Obligation.   When  and  as  declared  by  the
Corporation's  board of directors and to the extent  permitted under the General
Corporation Law of Delaware, the Corporation shall pay preferential dividends to
the holders of the  Preferred  Stock as  provided  in this  Section 1. Except as
otherwise  provided herein,  dividends on each Preferred Share shall accrue on a
daily  basis at the rate of 8% per  annum  of the sum of the  Liquidation  Value
thereof plus all accumulated and unpaid  dividends  thereon,  from and including
the Date of Issuance of such Preferred  Share to and including the date on which
the  Liquidation  Value of such  Preferred  Share  (plus all  accrued and unpaid
dividends  thereon)  is paid or the  date  on  which  such  Preferred  Share  is
converted into shares of Common Stock  hereunder.  Such  dividends  shall accrue
whether or not they have been  declared  and  whether or not there are  profits,
surplus or other funds of the Corporation  legally  available for the payment of
dividends.

                  1B.  Dividend  Reference  Dates.  To the  extent not paid on a
Dividend Reference Date, with the initial Dividend Reference Date being February
28, 1997, all dividends which have accrued on each Preferred  Share  outstanding
since the latest preceding  Dividend  Reference Date (or the Date of Issuance of
such Preferred  Share, if later) ending upon each such Dividend  Reference Date,
and, in the case of each Preferred  Share  outstanding  that was issued upon the
Old  ONS  Preferred   Share   Conversion,   all  dividends  that  were  accrued,
accumulated, and unpaid at the time of the Old ONS Preferred Share Conversion on
the Old ONS Preferred Share that was converted into such Preferred Share,  shall
be  accumulated  and shall  remain  accumulated  dividends  with respect to such
Preferred Share until paid.

                  1C.  Distribution  of  Partial  Dividend  Payments.  Except in
connection  with  redemptions or repurchases  (i) pursuant to paragraph 4A or 4B
below,  (ii) in compliance  with paragraph 4H below, or (iii) as provided in the
Purchase  Agreement,  if at any time the  Corporation  pays  less than the total
amount of  dividends  then accrued with  respect to the  Preferred  Stock,  such
payment shall be distributed ratably among the holders thereof based upon the

<PAGE>



                  aggregate accrued but unpaid dividends on the Preferred Shares
held by each such holder and such  payment  shall be applied  first to dividends
which have accrued on such  Preferred  Shares during the period since the latest
preceding Dividend Reference Date and second to reduce any accumulated dividends
with respect to such Preferred Shares.

                  Section 2.        Liquidation.

                  Upon any Liquidation,  each holder of Preferred Stock shall be
entitled to be paid,  before any distribution or payment is made upon any Junior
Securities,  an  amount  in cash  equal  to the  greater  of (a)  the  aggregate
Liquidation  Value  (plus all  accrued  and unpaid  dividends)  of all shares of
Preferred Stock held by such holder or (b) the amount which would be distributed
with  respect to the shares of Common  Stock  (including  fractional  shares for
purposes  of this  calculation)  into which such shares of  Preferred  Stock are
convertible (assuming conversion of all outstanding Preferred Stock) immediately
prior to the record date for such  distribution  (or, if there is no such record
date,  then the date as of which the  holders of Common  Stock  entitled to such
distribution  are  determined);  and the holders of Preferred Stock shall not be
entitled to any further payment.  If upon any such Liquidation the Corporation's
assets  to  be  distributed  among  the  holders  of  the  Preferred  Stock  are
insufficient  to permit  payment to such holders of the  aggregate  amount which
they are entitled to be paid, then the entire assets to be distributed  shall be
distributed  ratably  among such holders  based upon the  aggregate  Liquidation
Value (plus all accrued and unpaid  dividends) of the  Preferred  Shares held by
each such holder.  Prior to such Liquidation,  the Corporation shall declare for
payment all accrued and unpaid  dividends  with respect to the Preferred  Stock.
(Payment of the greater of the amounts  specified in clauses (a) and (b) of this
Section 2 in respect of such Preferred Shares shall  constitute  payment of such
declared   dividends.)  The  Corporation  shall  mail  written  notice  of  such
Liquidation,  not less than 60 days prior to the payment date stated therein, to
each record holder of Preferred Stock.

                  Section 3.        [Reserved.]

                  Section 4.        Redemptions.

                  4A.      Redemption at Option of Corporation.

                  (i) The  Corporation may at any time redeem all or, subject to
paragraph  4E  below,  any of  the  Preferred  Shares  then  outstanding  at the
Redemption  Price,  provided  that no redemption  pursuant to this  paragraph 4A
shall be for Preferred Shares with an aggregate  Liquidation  Value of less than
$1,000,000 (or such lesser number of Preferred Shares then outstanding).


<PAGE>



(ii) The Corporation may in connection with a  Reorganization  redeem all or any
of the Preferred Shares then outstanding at the Redemption Price, payable at the
time of the consummation of the Reorganization as follows:

                  (a)      first,  in Freely  Tradeable  Securities in an amount
                           not to exceed the lesser of (1) the Redemption  Price
                           of such Preferred Shares and (2) the amount of Freely
                           Tradeable   Securities   that,  if  such  holder  had
                           converted  such  Preferred  Shares into Common  Stock
                           immediately prior to such Reorganization,  would have
                           been  issued to such holder in  connection  with such
                           Reorganization  in respect  of such  shares of Common
                           Stock; and

                  (b)      second,  the balance of the Redemption Price (if any)
                           in cash.

Notwithstanding paragraph 4H hereof, if the Corporation seeks the consent of the
holders of Preferred Stock to any Reorganization  under  subparagraph  3D(iv) of
the Purchase  Agreement,  and the  affirmative  consent of the holders  required
thereunder is not obtained,  the  Corporation may redeem at or prior to the time
of the  consummation  of such  Reorganization  and  pursuant  to this  paragraph
4A(ii),  all (but not  less  than  all) of the  Preferred  Shares  held by those
holders that did not affirmatively consent to such transaction.

                  4B.      Redemptions at the Option of the Holder.

                  (i) At any time after the fifth  anniversary  of the  Closing,
subject to subparagraph 4B(ii) below, each holder of Preferred Stock may request
redemption of all or a portion of the Preferred  Shares owned by such holder for
a price equal to the Redemption  Price.  Within five Business Days after receipt
of such request,  the Corporation shall give written notice to all other holders
of  Preferred  Stock,  and such other  holders may request  redemption  of their
Preferred  Shares by  delivering  written  notice to the  Corporation  within 10
Business Days after receipt of the Corporation's  notice.  The Corporation shall
pay the Redemption  Price of all Preferred Shares whose redemption has been duly
requested  pursuant to this paragraph 4B within 30 days after its receipt of the
initial request for such redemption.

                  Notwithstanding  the  above,  the  Corporation  shall  not  be
obligated  pursuant to this paragraph 4B to redeem any Preferred Share initially
issued  to a Small  Business  Investment  Company  licensed  by the  U.S.  Small
Business  Administration before the fifth anniversary of the Date of Issuance of
such Preferred Share,  provided that all such outstanding Preferred Shares shall
be  counted  as held by their  holders  for  purposes  of all pro rata and other
calculations.


<PAGE>



(ii) Notwithstanding the provisions of subparagraph 4B(i) above, the Corporation
shall not be obligated to repurchase, pursuant to this paragraph 4B:

                           (a) on a  cumulative  basis,  (x)  before  the  sixth
         anniversary  of the Closing,  a number of shares of Preferred  Stock in
         excess of  one-third  of all shares of  Preferred  Stock  issued by the
         Corporation at any time (for purposes of such calculation,  taking into
         account both repurchases  under this paragraph 4B and repurchases under
         paragraph  6A of the  Purchase  Agreement),  and (y) before the seventh
         anniversary  of the Closing,  a number of shares of Preferred  Stock in
         excess of  two-thirds  of all shares of  Preferred  Stock issued by the
         Corporation at any time (for purposes of such calculation,  taking into
         account both repurchases  under this paragraph 4B and repurchases under
         paragraph  6A of the  Purchase  Agreement)  (and at no time  shall  any
         initial  holder  and its  transferees  be  entitled  to sell  shares of
         Preferred Stock to the Corporation pursuant to this paragraph 4B to the
         extent that the aggregate number of such shares of Preferred Stock sold
         by such Persons at or before that time pursuant to this paragraph 4B or
         pursuant to paragraph 6A of the Purchase Agreement (limited in the case
         of a  transferee  to shares of  Preferred  Stock  acquired  directly or
         indirectly  from,  or acquired in respect of Preferred  Stock  acquired
         directly  or  indirectly   from,  such  initial  holder)  would,  on  a
         cumulative basis,  exceed an amount equal to (I) the maximum cumulative
         number of shares which the  Corporation may be required to redeem under
         this subparagraph 4B(ii)(a) at such time, multiplied by (II) a fraction
         (x)  the   numerator  of  which  is  the  aggregate   number,   without
         duplication,  of shares of Preferred Stock issued by the Corporation at
         any  time  that  was  held by such  holders  (limited  in the case of a
         transferee to shares of Preferred Stock acquired directly or indirectly
         from, or acquired in respect of Preferred  Stock  acquired  directly or
         indirectly from, such initial holder), and (y) the denominator of which
         is the aggregate number,  without  duplication,  of shares of Preferred
         Stock issued by the Corporation at any time); and

                           (b) for a  period  of 180  days  after  the  date the
         Corporation  redeems  shares of Preferred  Stock  pursuant to paragraph
         4B(i),  any  shares  of  Preferred  Stock  pursuant  to a  request  for
         redemption  under paragraph 4B(i) that is requested  subsequent to, and
         not as part of, such prior redemption.

                  4C. Redemption  Payment.  For each Preferred Share which is to
be redeemed (and except as otherwise  provided in paragraph  4A(ii) above),  the
Corporation  shall be  obligated  on the  Redemption  Date to pay to the  holder
thereof (upon surrender by such holder at the Corporation's  principal office of
the  certificate  representing  such  Preferred  Share) an amount in immediately
available  funds equal to the Redemption  Price of such Preferred  Share. If the
funds of the Corporation legally available for redemption of Preferred Shares on
any  Redemption  Date are  insufficient  to redeem the total number of Preferred
Shares to

<PAGE>



                  be  redeemed  on such  date,  those  funds  which are  legally
available  shall be used to redeem  the  maximum  possible  number of  Preferred
Shares  ratably among the holders of the Preferred  Shares to be redeemed  based
upon the aggregate  Redemption  Price of the Preferred  Shares held by each such
holder and the remaining Preferred Shares will remain  outstanding.  At any time
thereafter  when additional  funds of the Corporation are legally  available for
the  redemption of Preferred  Shares,  such funds shall  immediately  be used to
redeem the balance of the  Preferred  Shares  which the  Corporation  has become
obligated to redeem on any  Redemption  Date but which it has not  redeemed.  In
connection  with any  redemption of Preferred  Stock pursuant to this Section 4,
the  Corporation  shall declare for payment all  dividends  that are accrued and
unpaid as of the Redemption Date with respect to the Preferred  Shares which are
to be redeemed on such  Redemption  Date.  (Payment of the  Redemption  Price in
respect of such  Preferred  Shares  shall  constitute  payment of such  declared
dividends.)

                  4D. Notice of Redemption.  The Corporation  shall mail written
notice of each  redemption of any Preferred  Stock to each record holder thereof
not  more  than 60 nor  less  than 30  days  prior  to the  date on  which  such
redemption  is to be made in the case of a redemption  pursuant to paragraph 4A,
and not less than 5 Business Days prior to the date on which such  redemption is
to be made in the case of a redemption  pursuant to  paragraph  4B. Upon mailing
any such notice of redemption,  the Corporation shall become obligated to redeem
the total  number of  Preferred  Shares  specified in such notice at the time of
redemption  specified therein.  In case fewer than the total number of Preferred
Shares   represented  by  any  certificate  are  redeemed,   a  new  certificate
representing  the number of unredeemed  Preferred  Shares shall be issued to the
holder  thereof  without cost to such holder  within three  Business  Days after
surrender of the certificate representing the redeemed Preferred Shares.

                  4E.  Determination  of the Number of Each  Holder's  Preferred
Shares to be Redeemed.  The number of Preferred  Shares to be redeemed from each
holder thereof in redemptions pursuant to paragraph 4A(i) shall be the number of
Preferred Shares  determined by multiplying the total number of Preferred Shares
to be  redeemed  by a  fraction,  the  numerator  of which  shall  be the  total
Redemption  Price  of  Preferred  Shares  then  held  by  such  holder  and  the
denominator of which shall be the aggregate Redemption Price of Preferred Shares
then outstanding.

                  4F.  Dividends  After  Redemption  Date. No Preferred Share is
entitled to any dividends  accruing after the Redemption Date. On the Redemption
Date of any Preferred  Share,  all rights of the holder of such Preferred  Share
shall cease, and such Preferred Share shall not be deemed to be outstanding.

                  4G.  Redeemed or  Otherwise  Acquired  Preferred  Shares.  Any
Preferred  Shares which are redeemed or  otherwise  acquired by the  Corporation
thereupon shall be retired. All such shares shall upon their retirement become

<PAGE>



authorized but unissued shares of preferred stock of the Corporation and may not
be  reissued as  Preferred  Stock but may be reissued as part of a new series of
preferred  stock to be  created by  resolution  or  resolutions  of the board of
directors,  subject to the conditions or  restrictions  on issuance set forth in
the certificate of incorporation of the Corporation.

                  4H. Other Redemptions or Acquisitions. Neither the Corporation
nor any Subsidiary shall redeem or otherwise acquire any Preferred Stock, except
as expressly authorized herein or pursuant to the Purchase Agreement or pursuant
to a purchase offer made pro rata to all holders of Preferred Stock on the basis
of the aggregate  Redemption  Price of the  Preferred  Shares owned by each such
holder.

                  Section 5.        Voting Rights.

                  The holders of the Preferred Stock shall be entitled to notice
of all stockholders  meetings in accordance with the Corporation's  bylaws,  and
except as otherwise required by law, the holders of the Preferred Stock shall be
entitled  to  vote  on all  matters  submitted  to the  stockholders  for a vote
together with the holders of the Common Stock voting  together as a single class
with  each  share of  Common  Stock  entitled  to one vote per  share,  and each
Preferred  Share  (including  fractional  shares)  entitled to one vote for each
share of Common Stock that would be issuable upon  conversion of such  Preferred
Share at the time the vote is taken.

                  Section 6.        Conversion.

                  6A.      Conversion Procedure.

                  (i) At any time  and  from  time to time  after  the  issuance
thereof,  any holder of Preferred  Stock may convert all or any of the Preferred
Shares  (including any fraction of a Preferred Share) held by such holder into a
number of shares of Common Stock computed by multiplying the number of Preferred
Shares to be converted by the  Liquidation  Value and dividing the result by the
Conversion Price then in effect.

                  (ii) Each  conversion  of  Preferred  Stock shall be deemed to
have  been  effected  as of the  close of  business  on the  date on  which  the
certificate or certificates  representing  the Preferred  Shares to be converted
have been surrendered at the principal  office of the Corporation.  At such time
as such conversion has been effected, the rights of the holder of such Preferred
Shares as such holder  shall  cease,  all accrued and unpaid  dividends  on such
Preferred  Shares shall be deemed to have been  forfeited  immediately  prior to
such  conversion,  and  the  Person  or  Persons  in  whose  name or  names  any
certificate  or  certificates  for shares of Common  Stock are to be issued upon
such  conversion  shall be deemed to have become the holder or holders of record
of the shares of Common Stock represented thereby.


<PAGE>



                  (iii) The conversion  rights of any Preferred Share subject to
redemption  hereunder  shall terminate on the Redemption Date for such Preferred
Share  unless  the  Corporation  has  failed to pay to the  holder  thereof  the
Redemption Price thereof.

                  (iv)   Notwithstanding   any  other  provision  hereof,  if  a
conversion  of any Preferred  Shares is to be made in  connection  with a Public
Offering,  such  conversion may, at the election of the holder of such Preferred
Shares,  be conditioned upon the  consummation of the Public Offering,  in which
case such conversion  shall not be deemed to be effective until the consummation
of the Public Offering.

                  (v) As soon as possible  after a conversion  has been effected
(but in any event  within five  Business  Days in the case of  subparagraph  (a)
below), the Corporation shall deliver to the converting holder:

                           (a) a certificate or  certificates  representing  the
        number of shares of Common Stock  issuable by reason of such  conversion
        in such  name or names and such  denomination  or  denominations  as the
        converting holder has specified;

                           (b) payment of the amount payable under  subparagraph
        (viii) below with respect to such conversion; and

                           (c) a certificate  representing  any Preferred Shares
        which were  represented by the certificate or certificates  delivered to
        the  Corporation in connection  with such  conversion but which were not
        converted.

                  (vi) The issuance of  certificates  for shares of Common Stock
upon  conversion of Preferred  Stock shall be made without charge to the holders
of such  Preferred  Stock for any issuance tax in respect  thereof or other cost
incurred by the  Corporation in connection  with such conversion and the related
issuance of shares of Common Stock.

                  (vii) The  Corporation  shall not close its books  against the
transfer  of  Preferred  Stock  or of  Common  Stock  issued  or  issuable  upon
conversion  of Preferred  Stock in any manner which  interferes  with the timely
conversion of Preferred Stock.  The Corporation  shall assist and cooperate (but
the Corporation  shall not be required to expend  substantial  efforts or funds)
with any holder of Preferred Shares required to make any governmental filings or
obtain any  governmental  approval prior to or in connection with any conversion
of Preferred Shares hereunder (including, without limitation, making any filings
required to be made by the Corporation).


<PAGE>



                  (viii) If any  fractional  interest in a share of Common Stock
would,  except for the provisions of this subparagraph,  be deliverable upon any
conversion of a holder's Preferred Stock, the Corporation, in lieu of delivering
the fractional  share therefor,  shall pay an amount to the holder thereof equal
to the Market Price of such fractional interest as of the date of conversion.

                  (ix) The  Corporation  shall  at all  times  reserve  and keep
available out of its authorized but unissued shares of Common Stock,  solely for
the purpose of issuance upon the  conversion of the Preferred  Stock or exercise
of the  Warrants,  such  number  of shares of  Common  Stock  issuable  upon the
conversion of all  outstanding  Preferred  Stock and exercise of all outstanding
Warrants  which may then be  exercised.  All shares of Common Stock which are so
issuable  shall,  when  issued,  be duly  and  validly  issued,  fully  paid and
nonassessable and free from all taxes, liens and charges.  The Corporation shall
take all such  actions as may be  necessary  to ensure  that all such  shares of
Common  Stock  may be so  issued  without  violation  of any  applicable  law or
governmental  regulation (excluding Investment  Regulations) or any requirements
of any  domestic  securities  exchange  upon which shares of Common Stock may be
listed  (except  for  official  notice of issuance  which  shall be  immediately
delivered by the Corporation upon each such issuance).

                  6B.      Conversion Price.

                  (i) In order to  prevent  dilution  of the  conversion  rights
granted  under  this  subdivision,  the  Conversion  Price  shall be  subject to
adjustment from time to time pursuant to this Section 6.

                  (ii) If and  whenever  on or after the Date of Issuance of any
Preferred Share the Corporation issues or sells, or in accordance with paragraph
6C is deemed to have  issued or sold,  other than in an Excluded  Issuance,  any
share of Common  Stock for a  consideration  per share less than the  Conversion
Price  in  effect  immediately  prior  to such  time  with  respect  to any such
Preferred Share,  then forthwith upon such issue or sale the Conversion Price of
such Preferred Share shall be reduced to the lowest net price per share at which
any such share of Common Stock has been issued or sold or is deemed to have been
issued or sold.

                  6C. Effect on Conversion  Price of Certain Events.  Solely for
purposes of determining  the adjusted  Conversion  Price under paragraph 6B, the
following shall be applicable:

                  (i) Issuance of Rights or Options.  If the  Corporation in any
manner grants any Options and the lowest price per share for which any one share
of  Common  Stock is  issuable  upon the  exercise  of any such  Option  or upon
conversion or exchange of any  Convertible  Security is less than any Conversion
Price in effect  immediately  prior to the time of the  granting of such Option,
then such share of Common  Stock shall be deemed to have been issued and sold by
the Corporation at

<PAGE>



the time of the  granting  of such  Options  for such  price  per share and such
Conversion  Price shall be adjusted in accordance  with paragraph  6B(ii) above.
For purposes of this  paragraph,  the "lowest  price per share for which any one
share of  Common  Stock  is  issuable"  shall be equal to the sum of the  lowest
amounts of consideration (if any) received or receivable by the Corporation with
respect to any one share of Common Stock upon the  granting of the Option,  upon
exercise  of the Option  and upon  conversion  or  exchange  of the  Convertible
Security.  No further adjustment of such Conversion Price shall be made upon the
actual  issue of such  Common  Stock or of such  Convertible  Security  upon the
exercise  of such  Options or upon the actual  issue of such  Common  Stock upon
conversion or exchange of such Convertible Security.

                  (ii) Issuance of Convertible Securities. If the Corporation in
any manner  issues or sells any  Convertible  Security  and the lowest price per
share for which any one share of Common  Stock is issuable  upon  conversion  or
exchange thereof is less than any Conversion Price in effect  immediately  prior
to the time of such  issue or sale,  then such  share of Common  Stock  shall be
deemed  to have  been  issued  and  sold by the  Corporation  at the time of the
issuance  or sale of such  Convertible  Securities  for such price per share and
such  Conversion  Price shall be adjusted in accordance  with  paragraph  6B(ii)
above. For the purposes of this paragraph, the "lowest price per share for which
any one  share of  Common  Stock is  issuable"  shall be equal to the sum of the
lowest  amounts  of  consideration  (if  any)  received  or  receivable  by  the
Corporation  with  respect to any one share of Common Stock upon the issuance of
the Convertible Security and upon the conversion or exchange of such Convertible
Security.  No further adjustment of such Conversion Price shall be made upon the
actual issue of such Common Stock upon conversion or exchange of any Convertible
Security,  and if any such issue or sale of such  Convertible  Security  is made
upon exercise of any Options for which  adjustments of such Conversion Price had
been or are to be made  pursuant  to  other  provisions  of this  Section  6, no
further  adjustment  of such  Conversion  Price  shall be made by reason of such
issue or sale.

                  (iii)  Change  in  Option  Price or  Conversion  Rate.  If the
purchase price provided for in any Option, the additional consideration (if any)
payable upon the issue,  conversion or exchange of any Convertible  Security, or
the rate at which any Convertible  Security is convertible  into or exchangeable
for Common Stock change at any time, any Conversion  Price  previously  adjusted
with respect to such Option or Convertible Security and in effect at the time of
such change shall be readjusted to the Conversion Price which would have been in
effect at such time had such Option or Convertible  Security originally provided
for such changed purchase price, additional  consideration or changed conversion
rate, as the case may be, at the time initially granted, issued or sold.

                  (iv) Treatment of Expired Options and Unexercised  Convertible
Securities. Upon the expiration of any Option or the termination of any right to

<PAGE>



convert or exchange any  Convertible  Security  without the exercise of any such
Option or right, any Conversion Price then in effect hereunder shall be adjusted
to the  Conversion  Price  which  would  have been in effect at the time of such
expiration or termination had such Option or Convertible Security, to the extent
outstanding  immediately  prior to such  expiration or  termination,  never been
issued.

                  (v)  Calculation  of  Consideration  Received.  If any  Common
Stock,  Option or Convertible  Security is issued or sold or deemed to have been
issued or sold for cash, the consideration  received therefor shall be deemed to
be the amount  received by the Corporation  therefor.  In case any Common Stock,
Options or Convertible  Securities are issued or sold for a consideration  other
than cash,  the amount of the  consideration  other  than cash  received  by the
Corporation  shall be the fair value of such  consideration,  except  where such
consideration consists of securities,  in which case the amount of consideration
received by the Corporation  shall be the Market Price thereof as of the date of
receipt.  If any Common Stock,  Option or Convertible  Security is issued to the
owners of the  non-surviving  entity in connection  with any merger in which the
Corporation is the surviving  corporation,  the amount of consideration therefor
shall be deemed to be the fair value of such  portion of the assets and business
of the non-surviving  entity as is attributable to such Common Stock, Options or
Convertible Securities,  as the case may be. The fair value of any consideration
other than cash and securities  shall be determined  jointly by the  Corporation
and the holders of 70% of the outstanding  Preferred Shares. If such parties are
unable to reach agreement within a reasonable  period of time, the fair value of
such consideration shall be determined by an independent  appraiser  experienced
in valuing such type of  consideration  jointly  selected by the Corporation and
the holders of 70% of the outstanding  Preferred  Shares.  The  determination of
such  appraiser  shall be final and binding upon the  parties,  and the fees and
expenses of such appraiser shall be borne by the Corporation.

                  (vi) Integrated Transactions.  In case any Option is issued in
connection  with  the  issue  or sale of other  securities  of the  Corporation,
together   comprising   one   integrated   transaction   in  which  no  specific
consideration  is  allocated to such Option by the parties  thereto,  the Option
shall be deemed to have been issued for a consideration of $.01.

                  (vii)  Treasury  Shares.  The number of shares of Common Stock
outstanding  at any given time does not include  shares  owned or held by or for
the account of the  Corporation or any  Subsidiary,  and the  disposition of any
shares so owned or held shall be considered an issue or sale of Common Stock.

                  (viii) Record Date. If the Corporation fixes a record date for
determining  the holders of Common  Stock  entitled (a) to receive a dividend or
other distribution payable in Common Stock, Options or in Convertible Securities
or (b) to  subscribe  for or  purchase  Common  Stock,  Options  or  Convertible
Securities, then such record date shall be deemed to be the date of the issue or
sale of the shares of

<PAGE>
Common  Stock  deemed to have been issued or sold upon the  declaration  of such
dividend  or upon  the  making  of such  other  distribution  or the date of the
granting of such right of subscription or purchase, as the case may be.

                  6D.  Subdivision  or  Combination  of  Common  Stock.  If  the
Corporation  at any  time  subdivides  (by  any  stock  split,  stock  dividend,
recapitalization  or otherwise) one or more classes of its outstanding shares of
Common Stock into a greater  number of shares,  any  Conversion  Price in effect
immediately prior to such subdivision shall be proportionately  reduced,  and if
the  Corporation  at any time combines (by reverse stock split or otherwise) one
or more classes of its outstanding  shares of Common Stock into a smaller number
of shares,  any Conversion Price in effect immediately prior to such combination
shall be proportionately increased.

                  6E. Reorganization, Reclassification, Consolidation, Merger or
Sale.  In  connection  with any  Organic  Change,  the  Corporation  shall  make
appropriate  provisions (in form and substance  reasonably  satisfactory  to the
holders of 70% of the Preferred Shares then  outstanding) to insure that each of
the holders of Preferred  Stock shall  thereafter  have the right to acquire and
receive,  in lieu of or in addition to (as the case may be) the shares of Common
Stock immediately  theretofore  acquirable and receivable upon the conversion of
such holder's  Preferred  Stock,  such shares of stock,  securities or assets as
such holder would have received in connection  with such Organic  Change if such
holder had  converted  its  Preferred  Stock  immediately  prior to such Organic
Change.  In  each  such  case,  the  Corporation  shall  also  make  appropriate
provisions (in form and substance reasonably  satisfactory to the holders of 70%
of the Preferred Shares then  outstanding) to insure that the provisions of this
Section 6 and  Sections 7 and 8 hereof shall  thereafter  be  applicable  to the
Preferred Stock  (including,  in the case of any such  consolidation,  merger or
sale in which the  successor  entity  or  purchasing  entity  is other  than the
Corporation,  an immediate  adjustment of the Conversion  Price to the value for
the Common Stock reflected by the terms of such  consolidation,  merger or sale,
and a corresponding immediate adjustment in the number of shares of Common Stock
acquirable and receivable  upon  conversion of Preferred  Stock, if the value so
reflected is less than the Conversion Price in effect  immediately prior to such
consolidation, merger or sale).

                  6F.  Certain   Events.   If  any  event  occurs  of  the  type
contemplated by the provisions of this Section 6 but not expressly  provided for
by such  provisions  (including,  without  limitation,  the  granting  of  stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Corporation's  board of directors shall make an appropriate  adjustment
in each Conversion Price so as to protect the rights of the holders of Preferred
Stock;  provided that no such adjustment  shall increase any Conversion Price as
otherwise determined pursuant to this Section 6 or decrease the number of shares
of Conversion Stock issuable upon conversion of each share of Preferred Stock.

<PAGE>
                  6G.      Notices.

                  (i) Immediately  upon any adjustment of any Conversion  Price,
the  Corporation  shall give written  notice thereof to all holders of Preferred
Stock, setting forth in reasonable detail and certifying the calculation of such
adjustment.

                  (ii) The Corporation  shall give written notice to all holders
of Preferred  Stock at least 20 days prior to the date on which the  Corporation
closes  its books or fixes a record  date (a) with  respect to any  dividend  or
distribution  upon Common Stock,  (b) with respect to any pro rata  subscription
offer to  holders  of Common  Stock or (c) for  determining  rights to vote with
respect to any Organic Change or Liquidation.

                  (iii) The  Corporation  shall also give written  notice to the
holders  of  Preferred  Stock at least  20 days  prior to the date on which  any
Organic Change shall take place.

                  6H.  Mandatory  Conversion.  The  Corporation  may  require by
written notice to all holders of Preferred  Stock,  the conversion of all of the
outstanding  Preferred Stock, at the then applicable Conversion Price or Prices,
at any time after the second  anniversary of the Closing,  provided that (a) the
Closing Price of the Common Stock (adjusted proportionately for stock dividends,
stock splits,  combinations,  and similar  changes in the Common Stock occurring
after the Closing) on at least 30 of the 45 latest  trading days  preceding  the
date of the Corporation's  notice has been greater than (i) $12.50 per share, if
such notice is delivered  prior to the last day of the 30th month after Closing,
(ii)  $15.62 per share,  if such notice is  delivered  after the last day of the
30th month after Closing but prior to the third  anniversary of the Closing,  or
(iii)  $18.75  per  share,  if such  notice is  delivered  on or after the third
anniversary  of  the  Closing,   (b)  the  number  of  Public  Float  Securities
outstanding exceeds 20% of the number of shares of Common Stock outstanding on a
"fully diluted" basis (i.e.,  after giving effect to the exercise,  exchange and
conversion of all rights, options, warrants and convertible securities that are,
directly or indirectly,  exercisable or exchangeable  for, or convertible  into,
Common  Stock,   determined  without  regard  to  any  vesting   limitations  or
restrictions on exercise,  exchange or  conversion),  and (c) the holders of the
Preferred  Stock are not then  subject  to (and  will  not,  as a result of such
exercise,  become subject to) any agreement  restricting  the sale of the Common
Stock issued upon the conversion of the Preferred Stock.

                  Section 7.        Liquidating Dividends.

                  If the  Corporation  declares or pays a  Liquidating  Dividend
upon the  Common  Stock,  then  the  Corporation  shall  pay to the  holders  of
Preferred Stock at the time of payment  thereof the Liquidating  Dividends which
would have been paid on the shares of Common Stock had such Preferred Stock been
converted

<PAGE>
immediately  prior to the record  date fixed for  determining  the  stockholders
entitled to receive payment of such Liquidating Dividend,  or, if no record date
is fixed,  the date as of which the record  holders of Common Stock  entitled to
such dividends are to be determined.

                  Section 8.        Purchase Rights.

                  If at any time the  Corporation  grants,  issues  or sells any
Purchase  Rights  pro rata to the record  holders of any class of Common  Stock,
then each holder of Preferred Stock shall be entitled to acquire, upon the terms
applicable to such Purchase  Rights,  the aggregate  Purchase  Rights which such
holder  could  have  acquired  if such  holder  had held the number of shares of
Common Stock  acquirable  upon  conversion  of such  holder's  Preferred  Shares
immediately  before the date on which a record is taken for the grant,  issuance
or sale of such Purchase Rights,  or, if no such record is taken, the date as of
which the record  holders of Common  Stock are to be  determined  for the grant,
issue or sale of such Purchase Rights.

                  Section 9.    Consequences of Certain Events of Noncompliance.

                  (i) If an Event of  Noncompliance  of the  type  described  in
subparagraph  (ii) of the definition of Event of Noncompliance  has occurred and
has  continued  for a period of 30 days and is  continuing or any other Event of
Noncompliance  has occurred and is continuing,  the annual  dividend rate on the
Preferred  Stock shall  increase  immediately  by an increment of two percentage
points.  Thereafter,  until such time as no Event of Noncompliance  exists,  the
annual dividend rate shall increase  automatically at the end of each succeeding
90-day period by an  additional  increment of two  percentage  points (but in no
event shall the annual  dividend rate exceed 14%).  Any increase of the dividend
rate resulting from the operation of this  paragraph  shall  terminate as of the
close of business on the date on which no Event of Noncompliance exists, subject
to subsequent increases pursuant to this paragraph.

                  (ii) If both (a) either (1) an Event of  Noncompliance  of the
type  described  in  subparagraph  (i) or  (iii) of the  definition  of Event of
Noncompliance  has occurred and is continuing,  or (2) an Event of Noncompliance
of the type described in subparagraph (ii) or (iv) of the definition of Event of
Noncompliance  has  occurred  and has  continued  for a period of 60 days and is
continuing  and (b) the  holder or holders  of 70% of the  Preferred  Stock then
outstanding  have given  written  notice to the  Corporation  of their intent to
exercise their rights under this paragraph (ii) in connection with such Event of
Noncompliance  (which  notice may be given at any time after the  occurrence  of
such Event of Noncompliance)  and 30 days have lapsed since the date such notice
was  given,  then the  holder or  holders  of 70% of the  Preferred  Stock  then
outstanding  shall have the option to demand (by written notice delivered to the
Corporation  at any  time  thereafter  until  such  time as there is no Event of
Noncompliance in existence) redemption of all or any portion of the

<PAGE>
Preferred  Stock owned by such holder or holders at a price per Preferred  Share
equal to the  Liquidation  Value thereof (plus all accrued and unpaid  dividends
thereon).  The Corporation  shall give prompt written notice of such election to
the other  holders of  Preferred  Stock (but in any event within five days after
receipt of the initial demand for redemption),  and each such other holder shall
have the option to demand  redemption  of all or any  portion  of such  holder's
Preferred Stock by giving written notice thereof to the Corporation within seven
days after receipt of the Corporation's notice. The Corporation shall redeem all
Preferred  Stock as to which rights  under this  paragraph  have been  exercised
within 15 days after receipt of the initial demand for redemption.

                  (iii) If any Event of  Noncompliance  exists,  each  holder of
Preferred  Stock shall also have any other  rights which such holder is entitled
to under any  contract or  agreement at any time and any other rights which such
holder may have pursuant to applicable law.

                  Section 10.       Registration of Transfer.

                  The Corporation  shall keep at its principal office a register
for the registration of Preferred  Stock.  Upon the surrender of any certificate
representing  Preferred  Stock at such  place,  the  Corporation  shall,  at the
request of the record  holder of such  certificate,  execute and deliver (at the
Corporation's  expense) a new certificate or  certificates in exchange  therefor
representing in the aggregate the number of Preferred Shares  represented by the
surrendered  certificate.  Each such new certificate shall be registered in such
name and shall represent such number of Preferred  Shares as is requested by the
holder of the surrendered  certificate and shall be  substantially  identical in
form to the surrendered certificate, and dividends shall accrue on the Preferred
Stock  represented by such new certificate from the date to which dividends have
been  fully  paid  on  such  Preferred  Stock  represented  by  the  surrendered
certificate.

                  Section 11.       Replacement.

                  Upon  receipt  of  evidence  reasonably  satisfactory  to  the
Corporation (an affidavit of the registered holder shall be satisfactory) of the
ownership and the loss,  theft,  destruction  or  mutilation of any  certificate
evidencing Preferred Shares of any series of Preferred Stock, and in the case of
any such  loss,  theft or  destruction,  upon  receipt of  indemnity  reasonably
satisfactory  to the  Corporation  (provided  that if the holder is a  financial
institution  or  other  institutional  investor,  its  own  agreement  shall  be
satisfactory),  or, in the case of any such  mutilation  upon  surrender of such
certificate,  the Corporation shall (at its expense) execute and deliver in lieu
of such  certificate a new certificate of like kind  representing  the number of
Preferred Shares of such series represented by such lost,  stolen,  destroyed or
mutilated  certificate  and dated the date of such lost,  stolen,  destroyed  or
mutilated certificate,

<PAGE>
and  dividends  shall  accrue on the  Preferred  Stock  represented  by such new
certificate  from the date to which dividends have been fully paid on such lost,
stolen, destroyed or mutilated certificate.

                  Section 12.       Definitions.

                  "Business  Day" means a day on which banks are generally  open
for business in New York City.

                  "Closing"  has the  meaning  given  such term in the  Purchase
Agreement.

                  "Closing  Price"  of each  share  of  Common  Stock  or  other
security  means the composite  closing price of the sales of the Common Stock or
such other  security on all  securities  exchanges on which such security may at
the time be listed (as  reported in The Wall Street  Journal),  or, if there has
been no sale on any such exchange on any day, the average of the highest bid and
lowest  asked  prices of the  Common  Stock or such other  security  on all such
exchanges  at the end of such day,  or, if such  security is not so listed,  the
closing  price (or last price,  if  applicable)  of sales of the Common Stock or
such other  security  in the Nasdaq  National  Market (as  reported  in The Wall
Street  Journal)  on such day,  or if such  security is not quoted in the Nasdaq
National Market but is traded  over-the-counter,  the average of the highest bid
and lowest asked prices on such day in the  over-the-counter  market as reported
by  the  National  Quotation  Bureau  Incorporated,  or  any  similar  successor

                  1A.   General   Obligation.   When  and  as  declared  by  the
Corporation's  board of directors and to the extent  permitted under the General
Corporation Law of Delaware, the Corporation shall pay preferential dividends to
the holders of the  Preferred  Stock as  provided  in this  Section 1. Except as
otherwise  provided herein,  dividends on each Preferred Share shall accrue on a
daily  basis at the rate of 8% per  annum  of the sum of the  Liquidation  Value
thereof plus all accumulated and unpaid  dividends  thereon,  from and including
the Date of Issuance of such Preferred  Share to and including the date on which
the  Liquidation  Value of such  Preferred  Share  (plus all  accrued and unpaid
dividends  thereon)  is paid or the  date  on  which  such  Preferred  Share  is
converted into shares of Common Stock  hereunder.  Such  dividends  shall accrue
whether or not they have been  declared  and  whether or not there are  profits,
surplus or other funds of the Corporation  legally  available for the payment of
dividends.

                  1B.  Dividend  Reference  Dates.  To the  extent not paid on a
Dividend Reference Date, with the initial Dividend Reference Date being February

since the latest preceding  Dividend  Reference Date (or the Date of Issuance of
such Preferred  Share, if later) ending upon each such Dividend  Reference Date,
and, in the case of each Preferred  Share  outstanding  that was issued upon the
Old  ONS  Preferred   Share   Conversion,   all  dividends  that  were  accrued,
accumulated, and unpaid at the time of the Old ONS Preferred Share Conversion on
the Old ONS Preferred Share that was converted into such Preferred Share,  shall
be  accumulated  and shall  remain  accumulated  dividends  with respect to such
Preferred Share until paid.

                  1C.  Distribution  of  Partial  Dividend  Payments.  Except in
connection  with  redemptions or repurchases  (i) pursuant to paragraph 4A or 4B
below,  (ii) in compliance  with paragraph 4H below, or (iii) as provided in the
Purchase Agreement, if at any time the Corporation pays less than the

<PAGE>



total amount of dividends then accrued with respect to the Preferred Stock, such
payment shall be  distributed  ratably among the holders  thereof based upon the
aggregate accrued but unpaid dividends on the Preferred Shares held by each such
holder and such payment shall be applied  first to dividends  which have accrued
on such Preferred Shares during the period since the latest  preceding  Dividend
Reference  Date and second to reduce any  accumulated  dividends with respect to
such Preferred Shares.

                  Section 2.        Liquidation.

                  Subject  to  the  provisions  of  Section  2 of the  Series  A
Certificate:  upon any  Liquidation,  each  holder of  Preferred  Stock shall be
entitled to be paid,  before any distribution or payment is made upon any Junior

Liquidation  Value  (plus all  accrued  and unpaid  dividends)  of all shares of
Preferred Stock held by such holder or (b) the amount which would be distributed
with  respect to the shares of Common  Stock  (including  fractional  shares for
purposes  of this  calculation)  into which such shares of  Preferred  Stock are
convertible (assuming conversion of all outstanding Preferred Stock) immediately
prior to the record date for such  distribution  (or, if there is no such record
date,  then the date as of which the  holders of Common  Stock  entitled to such
distribution  are  determined),  and the holders of Preferred Stock shall not be
entitled  to  any  further  payment;  and  if  upon  any  such  Liquidation  the
Corporation's  assets to be distributed among the holders of the Preferred Stock
are insufficient to permit payment to such holders of the aggregate amount which
they are entitled to be paid, then the entire assets to be distributed  shall be
distributed  ratably  among such holders  based upon the  aggregate  Liquidation
Value (plus all accrued and unpaid  dividends) of the  Preferred  Shares held by
each such holder.  Prior to such Liquidation,  the Corporation shall declare for
payment all accrued and unpaid  dividends  with respect to the Preferred  Stock.
(Payment of the greater of the amounts  specified in clauses (a) and (b) of this
Section 2 in respect of such Preferred Shares shall  constitute  payment of such
declared   dividends.)  The  Corporation  shall  mail  written  notice  of  such
Liquidation,  not less than 60 days prior to the payment date stated therein, to
each record holder of Preferred Stock.

                  Section 3.        [Reserved.]

                  Section 4.        Redemptions.

                  4A.      Redemption at Option of Corporation.

                  (i) The  Corporation may at any time redeem all or, subject to
paragraph  4E  below,  any of  the  Preferred  Shares  then  outstanding  at the
Redemption  Price,  provided  that no redemption  pursuant to this  paragraph 4A
shall be for Preferred Shares with an aggregate Liquidation Value of less

<PAGE>
than  $1,000,000  (less the aggregate  liquidation  value of any Series A Shares
being redeemed) or such lesser number of Preferred Shares then outstanding.

                  (ii) The Corporation  may in connection with a  Reorganization
redeem all or any of the Preferred  Shares then  outstanding  at the  Redemption
Price, payable at the time of the consummation of the Reorganization as follows:

                           (a)  first,  in  Freely  Tradeable  Securities  in an
         amount  not to exceed the  lesser of (1) the  Redemption  Price of such
         Preferred  Shares  and (2) the  amount of Freely  Tradeable  Securities
         that, if such holder had converted  such  Preferred  Shares into Common
         Stock immediately prior to such Reorganization,  would have been issued
         to such holder in  connection  with such  Reorganization  in respect of
         such shares of Common Stock; and

                           (b)  second, the balance of the  Redemption Price (if
         any) in cash.

Notwithstanding paragraph 4H hereof, if the Corporation seeks the consent of the
holders of Preferred Stock to any Reorganization  under  subparagraph  3D(iv) of
the Purchase  Agreement,  and the  affirmative  consent of the holders  required
thereunder is not obtained,  the  Corporation may redeem at or prior to the time
of the  consummation  of such  Reorganization  and  pursuant  to this  paragraph
4A(ii),  all (but not  less  than  all) of the  Preferred  Shares  held by those
holders that did not affirmatively consent to such transaction.

                  4B.      Redemptions at the Option of the Holder.

                  (i) At any time after the fifth  anniversary  of the  Closing,
subject to subparagraph 4B(ii) below, each holder of Preferred Stock may request
redemption of all or a portion of the Preferred  Shares owned by such holder for
a price equal to the Redemption  Price.  Within five Business Days after receipt
of such request (or of any similar request under paragraph 4B(i) of the Series A
Certificate),  the Corporation shall give written notice to all other holders of
Preferred  Stock,  and  such  other  holders  may  request  redemption  of their
Preferred  Shares by  delivering  written  notice to the  Corporation  within 10
Business Days after receipt of the Corporation's  notice.  The Corporation shall
pay the Redemption  Price of all Preferred Shares whose redemption has been duly
requested  pursuant to this paragraph 4B within 30 days after its receipt of the
initial request for such redemption.

                  Notwithstanding  the  above,  the  Corporation  shall  not  be
obligated  pursuant to this paragraph 4B to redeem any Preferred Share initially
issued  to a Small  Business  Investment  Company  licensed  by the  U.S.  Small
Business Administration before the fifth anniversary of the Date

<PAGE>



of  Issuance  of such  Preferred  Share,  provided  that  all  such  outstanding
Preferred  Shares shall be counted as held by their  holders for purposes of all
pro rata and other calculations.

                  (ii)  Notwithstanding  the  provisions of  subparagraph  4B(i)
above,  the Corporation  shall not be obligated to repurchase,  pursuant to this
paragraph 4B:

                           (a) on a  cumulative  basis,  (x)  before  the  sixth
         anniversary  of the  Closing,  a number of shares of  Preferred  Stock,
         which when taken together with the number of Series A Shares  similarly
         repurchased,  exceeds one-third of all shares of Series A Preferred and
         Series B Preferred  issued by the Corporation at any time (for purposes
         of such  calculation,  taking into account both repurchases  under this
         paragraph  4B,   repurchases   under  paragraph  4B  of  the  Series  A
         Certificate  and  repurchases   under  paragraph  6A  of  the  Purchase
         Agreement),  and (y) before the seventh  anniversary of the Closing,  a
         number of shares of Preferred Stock, which when taken together with the
         number of Series A Shares similarly repurchased,  exceeds two-thirds of
         all shares of Series A Preferred  and Series B Preferred  issued by the
         Corporation at any time (for purposes of such calculation,  taking into
         account both  repurchases  under this paragraph 4B,  repurchases  under
         paragraph  4B  of  the  Series  A  Certificate  and  repurchases  under
         paragraph  6A of the  Purchase  Agreement)  (and at no time  shall  any
         initial  holder  and its  transferees  be  entitled  to sell  shares of
         Preferred Stock to the Corporation pursuant to this paragraph 4B to the
         extent that the  aggregate  number of shares of Series A Preferred  and
         Series B Preferred sold by such Persons at or before that time pursuant
         to  this  paragraph  4B,  pursuant  to  paragraph  4B of the  Series  A
         Certificate  or  pursuant to  paragraph  6A of the  Purchase  Agreement
         (limited  in the case of a  transferee  to shares of Series A Preferred
         and  Series B  Preferred  acquired  directly  or  indirectly  from,  or
         acquired  in  respect  of  Series A  Preferred  or  Series B  Preferred
         acquired  directly or indirectly from, such initial holder) would, on a
         cumulative basis,  exceed an amount equal to (I) the maximum cumulative
         number of shares which the  Corporation may be required to redeem under
         this  subparagraph  4B(ii)  (a) at  such  time,  multiplied  by  (II) a
         fraction (x) the  numerator of which is the aggregate  number,  without
         duplication,  of shares of Series A  Preferred  and Series B  Preferred
         issued by the  Corporation  at any time  that was held by such  holders
         (limited  in the case of a  transferee  to shares of Series A Preferred
         and  Series B  Preferred  acquired  directly  or  indirectly  from,  or
         acquired  in  respect  of Series A  Preferred  and  Series B  Preferred
         acquired directly or indirectly from, such initial holder), and (y) the
         denominator of which is the aggregate number, without duplication, of

<PAGE>



         shares of  Series A  Preferred  and  Series B  Preferred  issued by the
         Corporation at any time); and

                           (b) for a  period  of 180  days  after  the  date the
         Corporation  redeems shares of Series B Preferred pursuant to paragraph
         4B(i) (or Series A Preferred  pursuant to paragraph 4B(i) of the Series
         A Certificate), any shares of Preferred Stock pursuant to a request for
         redemption  under paragraph 4B(i) that is requested  subsequent to, and
         not as part of, such prior redemption.

                  4C. Redemption  Payment.  For each Preferred Share which is to
be redeemed (and except as otherwise  provided in paragraph  4A(ii) above),  the
Corporation  shall be  obligated  on the  Redemption  Date to pay to the  holder
thereof (upon surrender by such holder at the  Corporations  principal office of
the  certificate  representing  such  Preferred  Share) an amount in immediately
available funds equal to the Redemption Price of such Preferred  Share.  Subject
to the provisions of paragraph 4C of the Series A  Certificate:  if the funds of
the  Corporation  legally  available for  redemption of Preferred  Shares on any
Redemption Date are  insufficient to redeem the total number of Preferred Shares
to be redeemed on such date,  those funds which are legally  available  shall be
used to redeem the maximum possible number of Preferred Shares ratably among the
holders  of the  Preferred  Shares  to be  redeemed  based  upon  the  aggregate
Redemption  Price of the  Preferred  Shares  held by each  such  holder  and the
remaining Preferred Shares will remain  outstanding;  and at any time thereafter
when  additional  funds  of  the  Corporation  are  legally  available  for  the
redemption of Preferred  Shares,  such funds shall immediately be used to redeem
the balance of the Preferred  Shares which the Corporation has become  obligated
to redeem on any  Redemption  Date but which it has not redeemed.  In connection
with  any  redemption  of  Preferred  Stock  pursuant  to this  Section  4,  the
Corporation  shall declare for payment all dividends that are accrued and unpaid
as of the Redemption  Date with respect to the Preferred  Shares which are to be
redeemed on such Redemption Date. (Payment of the Redemption Price in respect of
such Preferred Shares shall constitute payment of such declared dividends.)

                  4D. Notice of Redemption.  The Corporation  shall mail written
notice of each  redemption  of any Series A Preferred  or Series B Preferred  to
each  record  holder of  Preferred  Stock not more than 60 nor less than 30 days
prior  to the  date on  which  such  redemption  is to be made in the  case of a
redemption   pursuant  to  paragraph  4A  (or  paragraph  4A  of  the  Series  A
Certificate),  and not less than 5 Business Days prior to the date on which such
redemption  is to be made in the case of a  redemption  pursuant to paragraph 4B
(or paragraph 4B of the Series A  Certificate).  Upon mailing any such notice of
redemption, the Corporation shall become obligated to

<PAGE>



redeem the total number of Preferred Shares specified in such notice at the time
of  redemption  specified  therein.  In case  fewer  than the  total  number  of
Preferred Shares represented by any certificate are redeemed,  a new certificate
representing  the number of unredeemed  Preferred  Shares shall be issued to the
holder  thereof  without cost to such holder  within three  Business  Days after
surrender of the certificate representing the redeemed Preferred Shares.

                  4E.  Determination  of the Number of Each  Holder's  Preferred
Shares to be Redeemed.  The number of Preferred  Shares to be redeemed from each
holder thereof in redemptions pursuant to paragraph 4A(i) shall be the number of
Preferred Shares  determined by multiplying the total number of Preferred Shares
to be  redeemed  by a  fraction,  the  numerator  of which  shall  be the  total
Redemption  Price  of  Preferred  Shares  then  held  by  such  holder  and  the
denominator of which shall be the aggregate Redemption Price of Preferred Shares
then outstanding.

                  4F.  Dividends  after  Redemption  Date. No Preferred Share is
entitled to any dividends  accruing after the Redemption Date. On the Redemption
Date of any Preferred  Share,  all rights of the holder of such Preferred  Share
shall cease, and such Preferred Share shall not be deemed to be outstanding.

                  4G.  Redeemed or  Otherwise  Acquired  Preferred  Shares.  Any
Preferred  Shares which are redeemed or  otherwise  acquired by the  Corporation
thereupon shall be retired.  All such shares shall upon their retirement  become
authorized but unissued shares of preferred stock of the Corporation and may not
be  reissued as  Preferred  Stock but may be reissued as part of a new series of
preferred  stock to be  created by  resolution  or  resolutions  of the board of
directors,  subject to the conditions or  restrictions  on issuance set forth in
the certificate of incorporation of the Corporation.

                  4H. Other Redemptions or Acquisitions. Neither the Corporation
nor any Subsidiary shall redeem or otherwise acquire any Preferred Stock, except
as expressly authorized herein or pursuant to the Purchase Agreement or pursuant
to a purchase offer made pro rata to all holders of Preferred Stock on the basis
of the aggregate  Redemption  Price of the  Preferred  Shares owned by each such
holder.

                  Section 5         Voting Rights.

                  The holders of the Preferred Stock shall be entitled to notice
of all stockholders  meetings in accordance with the Corporation's  bylaws,  and
except as otherwise required by law, the holders of the Preferred Stock shall be
entitled  to  vote  on all  matters  submitted  to the  stockholders  for a vote
together with the holders of the Common Stock voting together as a single

<PAGE>



class with each share of Common Stock  entitled to one vote per share,  and each
Preferred  Share  (including  fractional  shares)  entitled to one vote for each
share of Common Stock that would be issuable upon  conversion of such  Preferred
Share at the time the vote is taken.

                  Section 6.        Conversion.

                  6A.      Conversion Procedure.

                  (i) At any time  and  from  time to time  after  the  issuance
thereof,  any holder of Preferred  Stock may convert all or any of the Preferred
Shares  (including any fraction of a Preferred Share) held by such holder into a
number of shares of Common Stock computed by multiplying the number of Preferred
Shares to be converted by the  Liquidation  Value and dividing the result by the
applicable Conversion Price then in effect.

                  (ii) Each  conversion  of  Preferred  Stock shall be deemed to
have  been  effected  as of the  close of  business  on the  date on  which  the
certificate or certificates  representing  the Preferred  Shares to be converted
have been surrendered at the principal  office of the Corporation.  At such time
as such conversion has been effected, the rights of the holder of such Preferred
Shares as such holder  shall  cease,  all accrued and unpaid  dividends  on such
Preferred  Shares shall be deemed to have been  forfeited  immediately  prior to
such  conversion,  and  the  Person  or  Persons  in  whose  name or  names  any
certificate  or  certificates  for shares of Common  Stock are to be issued upon
such  conversion  shall be deemed to have become the holder or holders of record
of the shares of Common Stock represented thereby.

                  (iii) The conversion  rights of any Preferred Share subject to
redemption  hereunder  shall terminate on the Redemption Date for such Preferred
Share  unless  the  Corporation  has  failed to pay to the  holder  thereof  the
Redemption Price thereof.

                  (iv)   Notwithstanding   any  other  provision  hereof,  if  a
conversion  of any Preferred  Shares is to be made in  connection  with a Public
Offering,  such  conversion may, at the election of the holder of such Preferred
Shares,  be conditioned upon the  consummation of the Public Offering,  in which
case such conversion  shall not be deemed to be effective until the consummation
of the Public Offering

                  (v) As soon as possible  after a conversion  has been effected
(but in any event  within five  Business  Days in the case of  subparagraph  (a)
below), the Corporation shall deliver to the converting holder:

                  (a) a certificate or certificates  representing  the number of
shares of Common Stock issuable by reason of such conversion in such name

<PAGE>



or names and such  denomination or  denominations  as the converting  holder has
specified;

                  (b) payment of the amount  payable under  subparagraph  (viii)
below with respect to such conversion; and

                  (c) a certificate representing any Preferred Shares which were
represented by the certificate or  certificates  delivered to the Corporation in
connection with such conversion but which were not converted.

                  (vi) The issuance of  certificates  for shares of Common Stock
upon  conversion of Preferred  Stock shall be made without charge to the holders
of such  Preferred  Stock for any issuance tax in respect  thereof or other cost
incurred by the  Corporation in connection  with such conversion and the related
issuance of shares of Common Stock.

                  (vii) The  Corporation  shall not close its books  against the
transfer  of  Preferred  Stock  or of  Common  Stock  issued  or  issuable  upon
conversion  of Preferred  Stock in any manner which  interferes  with the timely
conversion of Preferred Stock.  The Corporation  shall assist and cooperate (but
the Corporation  shall not be required to expend  substantial  efforts or funds)
with any holder of Preferred Shares required to make any governmental filings or
obtain any  governmental  approval prior to or in connection with any conversion
of Preferred Shares hereunder (including, without limitation, making any filings
required to be made by the Corporation).

                  (viii) If any  fractional  interest in a share of Common Stock
would,  except for the provisions of this subparagraph,  be deliverable upon any
conversion of a holder's Preferred Stock, the Corporation, in lieu of delivering
the fractional  share therefor,  shall pay an amount to the holder thereof equal
to the Market Price of such fractional interest as of the date of conversion.

                  (ix) The  Corporation  shall  at all  times  reserve  and keep
available out of its authorized but unissued shares of Common Stock,  solely for
the purpose of issuance upon the  conversion of the Preferred  Stock or exercise
of the  Warrants,  such  number  of shares of  Common  Stock  issuable  upon the
conversion of all  outstanding  Preferred  Stock and exercise of all outstanding
Warrants  which may then be  exercised.  All shares of Common Stock which are so
issuable  shall,  when  issued,  be duly  and  validly  issued,  fully  paid and
nonassessable and free from all taxes, liens and charges.  The Corporation shall
take all such  actions as may be  necessary  to ensure  that all such  shares of
Common  Stock  may be so  issued  without  violation  of any  applicable  law or
governmental  regulation (excluding Investment  Regulations) or any requirements
of any domestic securities exchange upon

<PAGE>



which  shares of  Common  Stock may be listed  (except  for  official  notice of
issuance which shall be immediately  delivered by the Corporation upon each such
issuance).

                  6B.      Conversion Price.

                  (i) In order to  prevent  dilution  of the  conversion  rights
granted  under  this  subdivision,  the  Conversion  Price  shall be  subject to
adjustment from time to time pursuant to this Section 6.

                  (ii) If and  whenever  on or after the Date of Issuance of any
Preferred Share the Corporation issues or sells, or in accordance with paragraph
6C is deemed to have  issued or sold,  other than in an Excluded  Issuance,  any
share of Common  Stock for a  consideration  per share less than the  Conversion
Price  in  effect  immediately  prior  to such  time  with  respect  to any such
Preferred Share,  then forthwith upon such issue or sale the Conversion Price of
such Preferred Share shall be reduced to the lowest net price per share at which
any such share of Common Stock has been issued or sold or is deemed to have been
issued or sold.

                  6C. Effect on Conversion  Price of Certain Events.  Solely for
purposes of determining  the adjusted  Conversion  Price under paragraph 6B, the
following shall be applicable:

                  (i) Issuance of Rights or Options.  If the  Corporation in any
manner grants any Options and the lowest price per share for which any one share
of  Common  Stock is  issuable  upon the  exercise  of any such  Option  or upon
conversion or exchange of any  Convertible  Security is less than any Conversion
Price in effect  immediately  prior to the time of the  granting of such Option,
then such share of Common  Stock shall be deemed to have been issued and sold by
the  Corporation  at the time of the granting of such Options for such price per
share and such  Conversion  Price shall be adjusted in accordance with paragraph
6B(ii) above.  For purposes of this  paragraph,  the "lowest price per share for
which any one share of Common  Stock is  issuable"  shall be equal to the sum of
the lowest  amounts of  consideration  (if any)  received or  receivable  by the
Corporation  with  respect to any one share of Common Stock upon the granting of
the Option,  upon exercise of the Option and upon  conversion or exchange of the
Convertible  Security.  No further  adjustment of such Conversion Price shall be
made upon the actual issue of such Common Stock or of such Convertible  Security
upon the  exercise of such Options or upon the actual issue of such Common Stock
upon conversion or exchange of such Convertible Security.

                  (ii) Issuance of Convertible Securities. If the Corporation in
any manner  issues or sells any  Convertible  Security  and the lowest price per
share for which any one share of Common Stock is issuable upon conversion

<PAGE>



or  exchange  thereof is less than any  Conversion  Price in effect  immediately
prior to the time of such issue or sale,  then such share of Common  Stock shall
be deemed to have been  issued  and sold by the  Corporation  at the time of the
issuance  or sale of such  Convertible  Securities  for such price per share and
such  Conversion  Price shall be adjusted in accordance  with  paragraph  6B(ii)
above. For the purposes of this paragraph, the "lowest price per share for which
any one  share of  Common  Stock is  issuable"  shall be equal to the sum of the
lowest  amounts  of  consideration  (if  any)  received  or  receivable  by  the
Corporation  with  respect to any one share of Common Stock upon the issuance of
the Convertible Security and upon the conversion or exchange of such Convertible
Security.  No further adjustment of such Conversion Price shall be made upon the
actual issue of such Common Stock upon conversion or exchange of any Convertible
Security,  and if any such issue or sale of such  Convertible  Security  is made
upon exercise of any Options for which  adjustments of such Conversion Price had
been or are to be made  pursuant  to  other  provisions  of this  Section  6, no
further  adjustment  of such  Conversion  Price  shall be made by reason of such
issue or sale.

                  (iii)  Change  in  Option  Price or  Conversion  Rate.  If the
purchase price provided for in any Option, the additional consideration (if any)
payable upon the issue,  conversion or exchange of any Convertible  Security, or
the rate at which any Convertible  Security is convertible  into or exchangeable
for Common Stock change at any time, any Conversion  Price  previously  adjusted
with respect to such Option or Convertible Security and in effect at the time of
such change shall be readjusted to the Conversion Price which would have been in
effect at such time had such Option or Convertible  Security originally provided
for such changed purchase price, additional  consideration or changed conversion
rate, as the case may be, at the time initially granted, issued or sold.

                  (iv) Treatment of Expired Options and Unexercised  Convertible
Securities. Upon the expiration of any Option or the termination of any right to
convert or exchange any  Convertible  Security  without the exercise of any such
Option or right, any Conversion Price then in effect hereunder shall be adjusted
to the  Conversion  Price  which  would  have been in effect at the time of such
expiration or termination had such Option or Convertible Security, to the extent
outstanding  immediately  prior to such  expiration or  termination,  never been
issued.

                  (v)  Calculation  of  Consideration  Received.  If any  Common
Stock,  Option or Convertible  Security is issued or sold or deemed to have been
issued or sold for cash, the consideration  received therefor shall be deemed to
be the amount  received by the Corporation  therefor.  In case any Common Stock,
Options or Convertible  Securities are issued or sold for a consideration  other
than cash, the amount of the consideration other than

<PAGE>



cash received by the Corporation shall be the fair value of such  consideration,
except where such consideration consists of securities, in which case the amount
of consideration  received by the Corporation  shall be the Market Price thereof
as of the date of receipt. If any Common Stock,  Option or Convertible  Security
is  issued to the  owners of the  non-surviving  entity in  connection  with any
merger in which the  Corporation  is the  surviving  corporation,  the amount of
consideration  therefor  shall be deemed to be the fair value of such portion of
the assets and business of the  non-surviving  entity as is attributable to such
Common Stock,  Options or Convertible  Securities,  as the case may be. The fair
value of any  consideration  other than cash and securities  shall be determined
jointly by the Corporation  and the holders of 70% of the outstanding  Preferred
Shares. If such parties are unable to reach agreement within a reasonable period
of  time,  the fair  value  of such  consideration  shall  be  determined  by an
independent  appraiser experienced in valuing such type of consideration jointly
selected by the Corporation and the holders of 70% of the outstanding  Preferred
Shares.  The determination of such appraiser shall be final and binding upon the
parties,  and the  fees and  expenses  of such  appraiser  shall be borne by the
Corporation.

                  (vi) Integrated Transactions.  In case any Option is issued in
connection  with  the  issue  or sale of other  securities  of the  Corporation,
together   comprising   one   integrated   transaction   in  which  no  specific
consideration  is  allocated to such Option by the parties  thereto,  the Option
shall be deemed to have been issued for a consideration of $.01.

                  (vii)  Treasury  Shares.  The number of shares of Common Stock
outstanding  at any given time does not include  shares  owned or held by or for
the account of the  Corporation or any  Subsidiary,  and the  disposition of any
shares so owned or held shall be considered an issue or sale of Common Stock.

                  (viii) Record Date. If the Corporation fixes a record date for
determining  the holders of Common  Stock  entitled (a) to receive a dividend or
other distribution payable in Common Stock, Options or in Convertible Securities
or (b) to  subscribe  for or  purchase  Common  Stock,  Options  or  Convertible
Securities, then such record date shall be deemed to be the date of the issue or
sale of the shares of Common  Stock  deemed to have been issued or sold upon the
declaration  of such dividend or upon the making of such other  distribution  or
the date of the granting of such right of subscription or purchase,  as the case
may be.

<PAGE>



Common Stock into a greater  number of shares,  any  Conversion  Price in effect
immediately prior to such subdivision shall be proportionately  reduced,  and if
the  Corporation  at any time combines (by reverse stock split or otherwise) one
or more classes of its outstanding  shares of Common Stock into a smaller number
of shares,  any Conversion Price in effect immediately prior to such combination
shall be proportionately increased.

                  6E. Reorganization, Reclassification, Consolidation, Merger or
Sale.  In  connection  with any  Organic  Change,  the  Corporation  shall  make
appropriate  provisions (in form and substance  reasonably  satisfactory  to the
holders of 70% of the Preferred Shares then  outstanding) to insure that each of
the holders of Preferred  Stock shall  thereafter  have the right to acquire and
receive,  in lieu of or in addition to (as the case may be) the shares of Common
Stock immediately  theretofore  acquirable and receivable upon the conversion of
such holder's  Preferred  Stock,  such shares of stock,  securities or assets as
such holder would have received in connection  with such Organic  Change if such
holder had  converted  its  Preferred  Stock  immediately  prior to such Organic
Change.  In  each  such  case,  the  Corporation  shall  also  make  appropriate
provisions (in form and substance reasonably  satisfactory to the holders of 70%
of the Preferred Shares then  outstanding) to insure that the provisions of this
Section 6 and  Sections 7 and 8 hereof shall  thereafter  be  applicable  to the
Preferred Stock  (including,  in the case of any such  consolidation,  merger or
sale in which the  successor  entity  or  purchasing  entity  is other  than the
Corporation,  an immediate  adjustment of the Conversion  Price to the value for
the Common Stock reflected by the terms of such  consolidation,  merger or sale,
and a corresponding immediate adjustment in the number of shares of Common Stock
acquirable and receivable  upon  conversion of Preferred  Stock, if the value so
reflected is less than the Conversion Price in effect  immediately prior to such
consolidation, merger or sale).

                  6F.  Certain   Events.   If  any  event  occurs  of  the  type
contemplated by the provisions of this Section 6 but not expressly  provided for
by such  provisions  (including,  without  limitation,  the  granting  of  stock
appreciation rights, phantom stock rights or other rights with equity features),
then the Corporation's  board of directors shall make an appropriate  adjustment
in each Conversion Price so as to protect the rights of the holders of Preferred
Stock;  provided that no such adjustment  shall increase any Conversion Price as
otherwise determined pursuant to this Section 6 or decrease the number of shares
of Conversion Stock issuable upon conversion of each share of Preferred Stock.

are not then  subject  to (and will not,  as a result of such  exercise,  become
subject to) any agreement  restricting  the sale of the Common Stock issued upon

                  If the  Corporation  declares or pays a  Liquidating  Dividend

converted  immediately  prior to the  record  date  fixed  for  determining  the
stockholders entitled to receive payment of such Liquidating Dividend, or, if no
record date is fixed,  the date as of which the record  holders of Common  Stock
entitled to such dividends are to be determined.

                  Section 8.        Purchase Rights.

                  If at any time the  Corporation  grants,  issues  or sells any

applicable to such Purchase  Rights,  the aggregate  Purchase  Rights which such
holder  could  have  acquired  if such  holder  had held the number of shares of
Common Stock  acquirable  upon  conversion  of such  holder's  Preferred  Shares
immediately  before the date on which a record is taken for the grant,  issuance
or sale of such Purchase Rights,  or, if no such record is taken, the date as of

has  continued  for a period of 30 days and is  continuing or any other Event of
Noncompliance  has occurred and is continuing,  the annual  dividend rate on the
Preferred  Stock shall  increase  immediately  by an increment of two percentage
points.  Thereafter,  until such time as no Event of Noncompliance  exists,  the
annual dividend rate shall increase  automatically at the end of each succeeding
90-day period by an  additional  increment of two  percentage  points (but in no
event shall the annual  dividend rate exceed 14%).  Any increase of the dividend
rate resulting from the operation of this  paragraph  shall  terminate as of the
close of business on the date on which no Event of Noncompliance exists, subject
to subsequent increases pursuant to this paragraph.

                  (ii) If both (a) either (1) an Event of  Noncompliance  of the
type  described  in  subparagraph  (i) or  (iii) of the  definition  of Event of

Noncompliance  has  occurred  and has  continued  for a period of 60 days and is

outstanding  have given  written  notice to the  Corporation  of their intent to
exercise their rights under this paragraph (ii) in connection with such Event of
Noncompliance  (which  notice may be given at any time after the  occurrence  of
such Event of Noncompliance) and 30 days

<PAGE>



have lapsed since the date such notice was given,  then the holder or holders of
70% of the Preferred Stock then outstanding  shall have the option to demand (by
written notice  delivered to the Corporation at any time  thereafter  until such
time as there is no Event of  Noncompliance  in existence)  redemption of all or
any  portion of the  Preferred  Stock owned by such holder or holders at a price
per Preferred Share equal to the Liquidation Value thereof (plus all accrued and
unpaid dividends  thereon).  The Corporation shall give prompt written notice of
such election (or of any similar  election under paragraph 9(ii) of the Series A
Certificate)  to the other  holders of Preferred  Stock (but in any event within
five days after  receipt of the initial  demand for  redemption),  and each such
other holder shall have the option to demand redemption of all or any portion of
such  holder's   Preferred  Stock  by  giving  written  notice  thereof  to  the
Corporation  within seven days after receipt of the  Corporation's  notice.  The
Corporation  shall  redeem all  Preferred  Stock as to which  rights  under this
paragraph have been exercised within 15 days after receipt of the initial demand
for redemption.

Preferred  Stock shall also have any other  rights which such holder is entitled
to under any  contract or  agreement at any time and any other rights which such
holder may have pursuant to applicable law.

request of the record  holder of such  certificate,  execute and deliver (at the
Corporation's  expense) a new certificate or  certificates in exchange  therefor
representing in the aggregate the number of Preferred Shares  represented by the
surrendered  certificate.  Each such new certificate shall be registered in such
name and shall represent such number of Preferred  Shares as is requested by the
holder of the surrendered  certificate and shall be  substantially  identical in
form to the surrendered certificate, and dividends shall accrue on the Preferred
Stock  represented by such new certificate from the date to which dividends have
been  fully  paid  on  such  Preferred  Stock  represented  by  the  surrendered
certificate.

                  Section 11.       Replacement.

satisfactory),  or, in the case of any such  mutilation  upon  surrender of such
certificate,  the Corporation shall (at its expense) execute and deliver in lieu
of such  certificate a new certificate of like kind  representing  the number of
Preferred Shares of such series represented by such lost,  stolen,  destroyed or
mutilated  certificate  and dated the date of such lost,  stolen,  destroyed  or
mutilated  certificate,  and  dividends  shall  accrue  on the  Preferred  Stock

                        SERIES C 6% CUMULATIVE REDEEMABLE
                           CONVERTIBLE PREFERRED STOCK

                  The  following  sections  set forth  the  powers,  rights  and
preferences,  and the qualifications,  limitations and restrictions  thereof, of
the Corporation's Series C 6% Cumulative Redeemable Convertible Preferred Stock.
Capitalized terms used herein are defined in Section 10 below.

                  Section 1.        Dividends.

                  1A. General Obligation.  Subject to the preferential rights of
Series A  Preferred  Stock or Series B  Preferred  Stock  ranking  senior to the
Preferred  Stock,  the record  holders of  Preferred  Stock shall be entitled to
receive  dividends,  when,  as and if  declared  by the  Corporation's  board of
directors  (the  "Board")  and  to  the  extent   permitted  under  the  General
Corporation Law of Delaware,  as amended, as provided in this Section 1, subject
to paragraph 1F.  Dividends shall accrue on a daily basis commencing on the Date
of Issuance of each Preferred  Share at the simple interest rate of 6% per annum
of the Liquidation Value thereof,  and shall be payable as provided in paragraph
1B. Dividends shall cease accruing upon the earliest to occur of (i) the date on
which the  Liquidation  Value of such Preferred  Share is paid, (ii) the date on
which such Preferred  Share is converted into shares of Common Stock  hereunder,
or (iii) the Maturity Date. Such dividends shall accrue whether or not they have
been  declared and whether or not there are net profits,  surplus or other funds
of the Corporation legally available for the payment of dividends.

                  1B.  Payment  of  Dividends.  Subject  to  the  provisions  of
paragraph 1A and paragraph 1F, dividends shall be payable, in arrears, following
each Dividend  Reference  Date within twenty days after such Dividend  Reference
Date.  The amount of the  dividend  on each  share of  Preferred  Stock  payable
following each Dividend  Reference Date shall equal the aggregate  amount of all
accrued and unpaid  dividends  on such share of  Preferred  Stock from the Prior
Dividend  Date (or, in the case of the first  dividend paid with respect to such
share,  the Date of Issuance of such  Preferred  Share)  through  such  Dividend
Reference  Date. To the extent any dividend is not paid within twenty days after
a Dividend Reference Date, all dividends which have accrued and remain unpaid on
each outstanding  Preferred Share through such Dividend  Reference Date shall be
accumulated  and  shall  remain  accumulated  dividends  with  respect  to  such
Preferred  Share until the date paid.  No interest,  dividend or sum of money in
lieu of  interest,  shall be  payable  in  respect  of any  dividend  payment or
payments that may be accrued and unpaid.

<PAGE>



                  1C.  Distribution  of  Partial  Dividend  Payments.  Except in
connection with redemptions or repurchases pursuant to paragraph 3A or 3B below,
if at any time the Corporation pays less than the total amount of dividends then
accrued with respect to the Preferred  Stock such payment  shall be  distributed
ratably among the holders  thereof  based upon the aggregate  accrued but unpaid
dividends  on the  Preferred  Shares held by each such  holder and such  payment
shall be applied first to dividends which have accrued on such Preferred  Shares
during the period since the latest preceding  Dividend Reference Date and second
to reduce any  previously  accumulated  dividends with respect to such Preferred
Shares.

                  1D.   Payment  of  Dividends  in  Common   Stock.   Except  as
specifically  provided  herein,  the  Corporation  shall pay all dividends  with
respect to the Preferred  Stock  (including,  in the case of a  redemption,  any
amount  equal to accrued  and  unpaid  dividends  constituting  a portion of the
Redemption Price) in fully paid and  non-assessable  shares of Common Stock. The
number of shares of Common  Stock  distributable  in a dividend on each share of
Preferred  Stock shall be equal to the  quotient  obtained  by dividing  (a) the
amount of such dividend,  as determined under paragraph 1B, by (b) the higher of
(i) the  Market  Price  of the  Common  Stock  on the  Dividend  Reference  Date
immediately  preceding  the  dividend  payment and (ii) the Series A/B  Dilution
Price.  When the Corporation  pays a dividend to the holders of Preferred Stock,
the Corporation  shall provide each holder of Preferred Stock with a calculation
of the  aggregate  number of shares of Common  Stock  payable in such  dividend,
including the computation of the Market Price.  If any fractional  interest in a
share of Common Stock would,  except for the  provisions  of this  sentence,  be
deliverable  upon  payment  of any  dividend  in  shares of  Common  Stock,  the
Corporation,  in lieu of delivering the fractional share therefor,  shall pay an
amount  to the  holder  thereof  equal to the  Market  Price of such  fractional
interest, calculated as set forth above in this paragraph 1D.

                  1E. Dividends on Junior Securities.  The Corporation shall not
declare and pay any dividends on Junior Securities unless all accrued and unpaid
dividends on the Preferred Stock have been paid in full.

                  1F. Certain Withholding Provisions.  Notwithstanding any other
provision of Section 1, and without limiting the generality of the Board's power
and authority  with respect to the  declaration  and payment of  dividends,  the
Board shall have and may  exercise  the power and  authority to provide that the
receipt  by each  record  holder of  Preferred  Shares  entitled  thereto of any
dividend  paid by the  Corporation  as  declared  on the issued and  outstanding
Preferred Shares shall be subject to the condition (the "Tax Payment Condition")
that the  Corporation  receive,  at or prior  to the  time for  payment  of such
dividend (the "Payment Time"), from or on behalf of such record holder,  payment
in full of the taxes, fees, duties,  assessments,  or other amounts, if any (the
"Tax"), that the Corporation is required under applicable law to pay or withhold
in  connection  with the  declaration  and payment to such record holder of such
dividend. If the Tax Payment Condition

<PAGE>



applies and has been satisfied,  or has been duly waived by the Corporation,  at
or prior to the Payment Time, at the Payment Time the Corporation shall pay such
dividend to such record holder. If the Tax Payment Condition applies but has not
been satisfied, and has not been duly waived by the Corporation,  at or prior to
the Payment Time, at the Payment Time the Corporation  shall pay the dividend to
which such record holder is entitled by irrevocably depositing and setting aside
such  dividend  with the  Secretary  of the  Corporation  as escrow  holder (the
"Escrow Holder").  Upon the Escrow Holder's  receipt,  from or on behalf of such
record  holder,  of payment in full of the Tax, plus any interest,  penalty,  or
additional amount to be paid or withheld as a result of the passage of time from
and after the Payment Time (the "Escrow  Termination  Time"),  the Escrow Holder
shall  release such  dividend to such record  holder and shall release such Tax,
and such additional amount if any, to the Corporation.  If such dividend is paid
in shares of Common Stock and is not received at or prior to the Payment Time by
the  record  holder of  Preferred  Shares  entitled  to  payment  thereof,  then
(notwithstanding  any  provision  hereof  to  the  contrary)  until  the  Escrow
Termination Time (and only until such time, whether or not the dividend has been
released by the Escrow Holder), such record holder shall not be entitled to vote
such shares of Common Stock for any purpose,  to receive payment of dividends or
other  distributions  on such shares of Common  Stock,  or to exercise any other
rights or privileges  in respect of such shares of Common Stock,  and the Escrow
Holder  shall have no right to vote such  shares of Common  Stock or to exercise
any other right or privilege in respect thereof  (whether in accordance with the
wishes or directions of such record holder or otherwise),  but the Escrow Holder
shall receive and hold in escrow until the Escrow Termination Time together with
such shares of Common Stock any dividends  paid or other  distributions  made on
such shares of Common  Stock and at the Escrow  Termination  Time shall  release
such dividends paid or other  distributions made on such shares of Common Stock,
if any, along with such shares of Common Stock.

                  Section 2.        Liquidation.

                  Subject to the provisions of Section 2 of each of the Series A
Certificate and the Series B Certificate:  upon any Liquidation,  each holder of
Preferred Stock shall be entitled to be paid, before any distribution or payment
is made upon any Junior  Securities,  an amount in cash equal to the  greater of
(a) the  aggregate  Liquidation  Value (plus an amount  equal to all accrued and
unpaid  dividends)  of all shares of Preferred  Stock held by such holder or (b)
the amount which would be distributed with respect to the shares of Common Stock
(including  fractional  shares for purposes of this calculation) into which such
shares  of  Preferred  Stock  are  convertible   (assuming   conversion  of  all
outstanding  Preferred  Stock)  immediately  prior to the  record  date for such
distribution (or, if there is no such record date, then the date as of which the
holders of Common Stock entitled to such  distribution are determined),  and the
holders of Preferred Stock shall not be entitled to any further payment;  and if
upon any such Liquidation the  Corporation's  assets to be distributed among the
holders of the Preferred Stock are insufficient to permit

<PAGE>



payment to such  holders of the  aggregate  amount which they are entitled to be
paid,  then the entire assets to be  distributed  shall be  distributed  ratably
among such holders based upon the aggregate  Liquidation Value (plus all accrued
and unpaid dividends) of the Preferred Shares held by each such holder. Prior to
such Liquidation, the Corporation shall (to the extent permitted by law) declare
for  payment  all accrued and unpaid  dividends  with  respect to the  Preferred
Stock, which dividends shall be payable in cash  notwithstanding  the provisions
of paragraph 1D. (Payment of the greater of the amounts specified in clauses (a)
and (b) of this Section 2 in respect of such Preferred  Shares shall  constitute
payment of such declared  dividends.) The Corporation  shall mail written notice
of such  Liquidation,  not less than 60 days prior to the  payment  date  stated
therein, to each record holder of Preferred Stock.

                  Section 3.        Redemptions.

                  3A.  Redemption at the Maturity Date. At the Maturity Date the
Corporation  shall redeem all of the  Preferred  Shares then  outstanding  for a
price equal to the Redemption  Price.  The Corporation  shall pay the Redemption
Price for the  Preferred  Shares within thirty (30) days after the Maturity Date
(or such later date upon which the certificates  evidencing the Preferred Shares
are surrendered to the Corporation).

                  3B.  Redemption at the Option of the Corporation.  At any time
after the Initial  Redemption Date, or, if prior to the Initial Redemption Date,
immediately  prior to the consummation of any  consolidation,  merger or sale in
which the successor  entity or purchasing  entity is other than the Corporation,
to the extent that it has funds legally sufficient therefor, the Corporation may
redeem all or, subject to the last sentence of this paragraph,  a portion of the
Preferred  Shares  then  outstanding  for the  Redemption  Price.  The number of
Preferred Shares to be redeemed from each holder thereof in a partial redemption
pursuant to this paragraph 3B shall be the number of Preferred Shares determined
by  multiplying  the  total  number of  Preferred  Shares  to be  redeemed  by a
fraction,  the  numerator  of  which  shall  be the  total  Redemption  Price of
Preferred  Shares then held by such holder and the denominator of which shall be
the aggregate Redemption Price of Preferred Shares then outstanding.

                  3C. Redemption  Payment.  For each Preferred Share which is to
be redeemed,  the Corporation  shall be obligated to pay the Redemption Price to
the holder thereof on the  Redemption  Date or such later date upon which occurs
the  surrender  by such  holder  at the  Corporation's  principal  office of the
certificate  representing  such  Preferred  Share.  Subject to the provisions of
paragraph  4C of the  Series A  Certificate  and  paragraph  4C of the  Series B
Certificate,  if the funds of the Corporation  legally  available for payment of
the cash portion of the Redemption  Price of Preferred  Shares on any Redemption
Date are  insufficient  to pay the cash portion of the Redemption  Price for the
total number of Preferred Shares to be

<PAGE>



redeemed on such date, those funds which are legally  available shall be used to
redeem the maximum  possible  number of such Preferred  Shares ratably among the
holders  of the  Preferred  Shares  to be  redeemed  based  upon  the  aggregate
Redemption  Price of the  Preferred  Shares  held by each  such  holder  and the
remaining Preferred Shares called for redemption will remain outstanding; and at
any time  thereafter  when  additional  funds  of the  Corporation  are  legally
available for the redemption of Preferred  Shares,  such funds shall immediately
be used to redeem the balance of the Preferred  Shares which the Corporation has
become obligated to redeem on any Redemption Date but which it has not redeemed.
Payment  of the  Redemption  Price in  respect of such  Preferred  Shares  shall
extinguish  all  rights  to  dividends  that are  accrued  and  unpaid as of the
Redemption Date with respect to the Preferred  Shares which are redeemed on such
Redemption Date.

                  3D. Notice of Redemption.  The Corporation  shall mail written
notice  of each  redemption  of any  Preferred  Stock to each  record  holder of
Preferred  Stock  not more  than 60 nor less  than 30 days  prior to the date on
which  such  redemption  is to be made  specifying  (a) the  number of shares of
Preferred Stock to be redeemed by the  Corporation and (b) the Redemption  Date.
Upon  mailing  any such  notice of  redemption,  the  Corporation  shall  become
obligated  to redeem the total  number of  Preferred  Shares  specified  in such
notice at the time of redemption  specified therein and upon the surrender on or
before such time of the certificates  representing such Preferred Shares. If one
or more holders of Preferred  Shares being  redeemed shall fail to surrender the
certificates  representing  such Preferred  Shares by the  Redemption  Date, the
Corporation shall pay the Redemption Price by irrevocably  depositing or setting
aside  the  required   amount  to  be  paid  promptly  upon  surrender  of  such
certificates.  Such  deposit  or  set  aside  shall  be  deemed  payment  of the
Redemption  Price to the holder for whom it is deposited  or set aside.  In case
fewer than the total number of Preferred  Shares  represented by any certificate
are redeemed, a new certificate  representing the number of unredeemed Preferred
Shares shall be issued to the holder thereof  without cost to such holder within
three Business Days after surrender of the certificate representing the redeemed
Preferred Shares.

                  3E.  Dividends after  Redemption Date. No Preferred Share that
is redeemed is entitled to any dividends  accruing after the Redemption Date. On
the  Redemption  Date of any Preferred  Share,  all rights of the holder of such
Preferred  Share shall cease,  and such Preferred Share shall be deemed to be no
longer outstanding.

                  3F.  Redeemed or  Otherwise  Acquired  Preferred  Shares.  Any
Preferred  Shares which are  redeemed,  converted  or otherwise  acquired by the
Corporation  thereupon  shall be  retired.  All such  shares  shall  upon  their
retirement  become  authorized  but unissued  shares of  preferred  stock of the
Corporation  and may not be reissued as  Preferred  Stock but may be reissued as
part of a new series

<PAGE>



of preferred  stock to be created by resolution or  resolutions  of the board of
directors,  subject to the conditions or  restrictions  on issuance set forth in
the certificate of incorporation of the Corporation.

                  Section 4.        Voting Rights.

                  The holders of the Preferred Stock shall be entitled to notice
of all stockholders  meetings in accordance with the Corporation's  bylaws,  and
except as otherwise required by law, the holders of the Preferred Stock shall be
entitled  to  vote  on all  matters  submitted  to the  stockholders  for a vote
together with the holders of the Common Stock voting  together as a single class
with  each  share of  Common  Stock  entitled  to one vote per  share,  and each
Preferred  Share  (including  fractional  shares)  entitled to one vote for each
whole  share of Common  Stock that would be  issuable  upon  conversion  of such
Preferred Share at the time the vote is taken.

                  Section 5.        Conversion.

                  5A.      Conversion Procedure.

                  (i) At any time  and  from  time to time  after  the  issuance
thereof,  any holder of Preferred  Stock may convert all or any of the Preferred
Shares  (including any fraction of a Preferred Share) held by such holder into a
number of shares of Common  Stock  equal to the sum of: (a) the number of shares
of Common Stock  computed by  multiplying  the number of Preferred  Shares to be
converted by the Liquidation Value of a Preferred Share, and dividing the result
by the Conversion Price then in effect,  plus (b) the number of shares of Common
Stock that would be payable if all accrued but unpaid  dividends  were  declared
and paid on the Preferred  Shares to be converted.  For purposes of  determining
the amount of  dividends  payable or that  would be  payable  with  respect to a
conversion  under Section 5, the date for  determining the Market Price shall be
the Business Day immediately preceding the date on which conversion is deemed to
have been effected.

                  (ii) Each  conversion  of  Preferred  Stock shall be deemed to
have  been  effected  as of the  close of  business  on the  date on  which  the
certificate or certificates  representing  the Preferred  Shares to be converted
have been surrendered at the principal office of the Corporation,  together with
written notice of the holder's desire to convert such Preferred  Shares. At such
time as such  conversion  has been  effected,  the  rights of the holder of such
Preferred  Shares as such holder shall cease, and the Person or Persons in whose
name or names any certificate or certificates  for shares of Common Stock are to
be issued  upon such  conversion  shall be deemed to have  become  the holder or
holders  of record of the  shares of Common  Stock  represented  thereby,  which
Common  Stock shall be deemed to have been  issued as of such time.  Issuance of
Common Stock by the  Corporation to effect any conversion  shall  extinguish all
rights to dividends that are accrued and unpaid as of the date

<PAGE>



on which conversion is to be made with respect to the Preferred Shares which are
to be converted on such date.

                  (iii) The conversion  rights of any Preferred Share subject to
redemption  hereunder  shall terminate on the Redemption Date for such Preferred
Share  unless  the  Corporation  has  failed to pay to the  holder  thereof  the
Redemption Price thereof.

                  (iv)   Notwithstanding   any  other  provision  hereof,  if  a
conversion  of any Preferred  Shares is to be made in  connection  with a Public
Offering or prior to a redemption,  such  conversion may, at the election of the
holder of such Preferred  Shares,  be conditioned  upon the  consummation of the
Public  Offering or the redemption  occurring on or before a specified  date, in
which  case  such  conversion  shall not be  deemed  to be  effective  until the
consummation of the Public Offering or unless the redemption occurs on or before
the specified date.

                  (v) As soon as possible  after a conversion  has been effected
(but in any event within three  Business  Days in the case of  subparagraph  (a)
below), the Corporation shall deliver to the converting holder:

                  (a)      a certificate or certificates representing the number
                           of shares of Common Stock  issuable by reason of such
                           conversion   in  such   name  or   names   and   such
                           denomination  or   denominations  as  the  converting
                           holder has specified;

                  (b)      payment  of the  amount  payable  under  subparagraph
                           (viii) below with respect to such conversion; and

                  (c)      a certificate representing any Preferred Shares which
                           were  represented by the  certificate or certificates
                           delivered to the  Corporation in connection with such
                           conversion but which were not converted.

                  (vi) The issuance of  certificates  for shares of Common Stock
upon  conversion of Preferred  Stock shall be made without charge to the holders
of such  Preferred  Stock for any issuance tax in respect  thereof or other cost
incurred by the  Corporation in connection  with such conversion and the related
issuance of shares of Common Stock.

                  (vii) The  Corporation  shall not close its books  against the
transfer  of  Preferred  Stock  or of  Common  Stock  issued  or  issuable  upon
conversion  of Preferred  Stock in any manner which  interferes  with the timely
conversion of Preferred Stock.  The Corporation  shall assist and cooperate (but
the Corporation  shall not be required to expend  substantial  efforts or funds)
with any holder of Preferred Shares required to make any governmental filings or
obtain any  governmental  approval prior to or in connection with any conversion
of Preferred Shares hereunder

<PAGE>



(including,  without  limitation,  making any filings required to be made by the
Corporation).

                  (viii) If any  fractional  interest in a share of Common Stock
would,  except for the provisions of this subparagraph,  be deliverable upon any
conversion of shares of a holder's Preferred Stock, the Corporation,  in lieu of
delivering  the  fractional  share  therefor,  shall pay an amount to the holder
thereof equal to the Market Price of such fractional interest as of the Business
Day immediately preceding the date of conversion.

                  (ix) The  Corporation  shall  at all  times  reserve  and keep
available out of its authorized but unissued shares of Common Stock,  solely for
the purpose of issuance upon the  conversion of the  Preferred  Stock,  not less
than the number of shares of Common Stock  issuable  upon the  conversion of all
outstanding  Preferred  Stock which may then be exercised.  All shares of Common
Stock which are so issuable  shall,  when  issued,  be duly and validly  issued,
fully paid and  nonassessable  and free from all taxes,  liens and charges.  The
Corporation  shall take all such  actions as may be necessary to ensure that all
such shares of Common Stock may be so issued without violation of any applicable
law or governmental  regulation or any  requirements of any domestic  securities
exchange  upon which shares of Common  Stock may be listed  (except for official
notice of issuance which shall be immediately  delivered by the Corporation upon
each such issuance).

                  5B.  Subdivision  or  Combination  of  Common  Stock.  If  the
Corporation  at any  time  subdivides  (by  any  stock  split,  stock  dividend,
recapitalization  or otherwise) the outstanding shares of one or more classes of
Common  Stock into a greater  number of shares,  the  Conversion  Price (and the
Trigger Price and Series A/B Dilution Price) in effect immediately prior to such
subdivision shall be proportionately reduced, and if the Corporation at any time
combines (by reverse stock split or otherwise) the outstanding  shares of one or
more classes of Common  Stock into a smaller  number of shares,  the  Conversion
Price  (and  the  Trigger  Price  and  Series  A/B  Dilution  Price)  in  effect
immediately prior to such combination shall be proportionately increased.

                  5C. Reorganization, Reclassification, Consolidation, Merger or
Sale. In connection with any Reorganization,  (i) the holders of Preferred Stock
shall  thereafter  have  the  right to  acquire  and  receive,  in lieu of or in
addition  to (as the  case  may be)  the  shares  of  Common  Stock  immediately
theretofore  acquirable  and  receivable  upon the  conversion  of such holder's
Preferred Stock, such shares of stock, securities,  cash or other assets (or, if
not practicably  attainable,  the reasonable  equivalent thereof) as such holder
would have received in connection  with such  Reorganization  if such holder had
converted its Preferred Stock immediately prior to such Reorganization, and (ii)
dividends  and amounts in respect of  dividends  hereunder  payable in shares of
Common  Stock prior to such  Reorganization  shall be  payable,  in lieu of each
share of Common Stock, in such

<PAGE>



shares of stock,  securities,  cash or other  assets (or  reasonable  equivalent
thereof) as the holder of one share of Common Stock received in connection  with
such Reorganization. The Corporation shall make appropriate provisions to ensure
that the requirements of the previous sentence are effected.  In each such case,
the  Corporation  shall  also make  appropriate  provisions  to ensure  that the
provisions of this Section 5 and Sections 6 and 7 shall thereafter be applicable
to the Preferred Stock.

                  5D.      Notices.

                  (i) Immediately  upon any adjustment of the Conversion  Price,
the  Corporation  shall give written  notice thereof to all holders of Preferred
Stock, setting forth in reasonable detail and certifying the calculation of such
adjustment.

                  (ii) The Corporation  shall give written notice to all holders
of Preferred  Stock at least 20 days prior to the date on which the  Corporation
closes  its books or fixes a record  date (a) with  respect to any  dividend  or
distribution  upon Common Stock,  (b) with respect to any pro rata  subscription
offer to  holders  of Common  Stock or (c) for  determining  rights to vote with
respect to any Liquidation or Reorganization.

                  5E.  Mandatory  Conversion.  The Corporation  may require,  by
written notice to all holders of Preferred  Stock,  the conversion of all of the
outstanding Preferred Stock into a number of shares of Common Stock equal to the
sum of: (a) the number of shares of Common  Stock  computed by  multiplying  the
number  of  Preferred  Shares  to be  converted  by the  Liquidation  Value of a
Preferred Share, and dividing the result by the applicable Conversion Price then
in effect,  plus (b) the number of shares of Common  Stock that would be payable
if all accrued but unpaid  dividends  were  declared  and paid on the  Preferred
Shares to be  converted;  provided  that the Closing  Price of the Common  Stock
(adjusted proportionately for stock dividends, stock splits,  combinations,  and
similar  changes in the Common  Stock  occurring  after the Closing) on at least
twenty (20) of the thirty (30) latest  trading  days  preceding  the date of the
Corporation's  notice has been greater than or equal to the Conversion Price. If
the  Corporation  shall require the conversion of the Preferred Stock under this
Section 5E within two years from the Initial Date of  Issuance,  then the number
of shares of Common Stock into which the shares of Preferred Stock are converted
shall be increased by the number of shares of Common Stock that would be payable
if the Corporation were immediately to declare and pay all dividends that in the
absence of conversion  would have accrued on such shares of Preferred Stock over
the six-month  period  immediately  following the date of conversion;  provided,
however,  that the total  dividends and amounts in respect of dividends  paid on
the Preferred Stock after the Date of Issuance thereof, including any additional
amounts in respect of dividends paid as a result of a required  conversion under
this Section 5E, shall not be less than the

<PAGE>



amount of  dividends  that would have accrued on all  outstanding  shares of the
Preferred Stock for one full year following the Initial Date of Issuance.

                  Any  conversion  of  shares  of  Preferred  Stock  under  this
Paragraph  5E shall be  effected  and be deemed to have been  effected as of the
close of business on the date on which the Corporation  provides  written notice
of such  conversion  to the  holders  of such  shares of  Preferred  Stock  (the
"Mandatory  Conversion  Time"),  and as of the Mandatory  Conversion  Time,  the
rights of the holders of the converted shares of Preferred Stock, as such, shall
cease and terminate,  such converted  shares of Preferred Stock shall be retired
in  accordance  with  paragraph  3F, the shares of Common  Stock into which such
shares of Preferred  Stock are converted shall be issued and deemed to have been
issued,  the  certificate(s)  that theretofore  represented  shares of Preferred
Stock thereafter shall represent the number of shares of Common Stock into which
the shares of Preferred Stock  theretofore  represented  thereby shall have been
converted, and the holder of any such certificate, upon the surrender thereof to
the  Corporation,  shall be  entitled  to  receive  from the  Corporation  a new
certificate  representing  the  number of shares of Common  Stock into which the
shares of  Preferred  Stock  theretofore  represented  thereby  shall  have been
converted.

                  5F.      Effect on Conversion Price of Certain Events.

                  (i) General.  In order to prevent  dilution of the  conversion
rights  granted under this Section 5, the  Conversion  Price shall be subject to
adjustment from time to time pursuant to this paragraph 5F.

                  (ii)  Adjustment  of Conversion  Price.  If and whenever on or
after the Date of Issuance the  Corporation  issues or sells,  or in  accordance
with  this  paragraph  5F is deemed to have  issued  or sold,  other  than in an
Excluded Issuance,  any share of Common Stock for a consideration per share less
than the Trigger  Price in effect  immediately  prior to such time (a  "Dilutive
Event"),  then  forthwith  upon  such  issue or sale in the  Dilutive  Event the
Conversion  Price shall be reduced by multiplying the Conversion Price in effect
immediately  before the Dilutive Event by a fraction,  the numerator of which is
the number of shares of Common  Stock that are  Outstanding  on an  As-Converted
Basis (as defined below)  immediately  before the Dilutive Event plus the number
of shares of Common Stock that could be  purchased  at the Trigger  Price at the
time of the Dilutive Event for the aggregate  consideration paid or payable upon
the sale or issuance of Common Stock in the Dilutive Event,  and the denominator
of which is the  number of shares of Common  Stock  that are  Outstanding  on an
As-Converted  Basis  immediately  before the  Dilutive  Event plus the number of
shares  that are  acquired  or to be  acquired  upon the sale or issuance of the
Common  Stock in the Dilutive  Event.  For  purposes of this  paragraph  5F(ii),
"Outstanding on an  As-Converted  Basis"  immediately  before the Dilutive Event
means the sum of (i) all Common Stock issued and outstanding  immediately before
the Dilutive Event plus (ii) all Common Stock issuable upon the

<PAGE>



exercise  of  Options  or  conversion  of  Convertible   Securities  outstanding
immediately before the Dilutive Event (other than Preferred Stock).

                  (iii) Issuance of Rights or Options. If the Corporation in any
manner  grants any  Options  and the price per share for which  shares of Common
Stock are issuable upon the exercise of any such Option is less than the Trigger
Price in effect  immediately  prior to the time of the  granting of such Option,
then such shares of Common Stock shall be deemed to have been issued and sold by
the  Corporation  at the time of the granting of such Options for such price per
share and the  Conversion  Price shall be adjusted in accordance  with paragraph
5F(ii) above.  For purposes of this  paragraph,  the "price per share" for which
shares of Common  Stock are  issuable  upon the  exercise of any Option shall be
equal to the sum of the amounts of consideration (if any) received or receivable
by the Corporation with respect to such shares of Common Stock upon the granting
of the Option and upon  exercise of the  Option.  No further  adjustment  of the
Conversion  Price shall be made upon the actual  issue of such Common Stock upon
the exercise of such Options.

                  (iv) Issuance of Convertible Securities. If the Corporation in
any manner issues or sells any Convertible  Security (or Options to purchase any
Convertible  Security)  and the price per share for shares of Common  Stock that
are issuable upon conversion or exchange  thereof is less than the Trigger Price
in effect  immediately  prior to the time of such issue or sale (or the granting
of such  Option),  then such shares of Common Stock shall be deemed to have been
issued and sold by the  Corporation  at the time of the issuance or sale of such
Convertible Securities (or the granting of such Option) for such price per share
and the Conversion  Price shall be adjusted in accordance with paragraph  5F(ii)
above.  For the  purposes  of this  paragraph,  the  "price per share" for which
shares  of  Common  Stock  are  issuable  upon  conversion  or  exchange  of any
Convertible  Security (or exercise of any Option therefor) shall be equal to the
sum of the  amounts of  consideration  (if any)  received or  receivable  by the
Corporation  upon the issuance of the Convertible  Security (or such Option) and
upon the  conversion  or exchange of such  Convertible  Security (or exercise of
such Option).  No further  adjustment of the Conversion Price shall be made upon
the  actual  issue of such  Common  Stock upon  conversion  or  exchange  of any
Convertible Security, and if any such issue or sale of such Convertible Security
is made upon  exercise of any Options for which  adjustments  of the  Conversion
Price had been or are to be made pursuant to other provisions of this Section 5,
no further  adjustment of the  Conversion  Price shall be made by reason of such
issue or sale.

                  (v) Change in Option Price or Conversion Rate. If the purchase
price provided for in any Option, the additional  consideration (if any) payable
upon the issue,  conversion or exchange of any Convertible Security, or the rate
at which any Convertible Security is convertible into or exchangeable for Common
Stock change at any time, any Conversion Price previously  adjusted with respect
to such Option or Convertible  Security and in effect at the time of such change
shall be

<PAGE>



readjusted to the Conversion  Price which would have been in effect at such time
had such Option or  Convertible  Security  originally  provided for such changed
purchase price, additional consideration or changed conversion rate, as the case
may be, at the time initially granted, issued or sold.

                  (vi) Treatment of Expired Options and Unexercised  Convertible
Securities. Upon the expiration of any Option or the termination of any right to
convert or exchange any  Convertible  Security  without the exercise of any such
Option or right, any Conversion Price then in effect hereunder shall be adjusted
to the  Conversion  Price  which  would  have been in effect at the time of such
expiration or termination had such Option or Convertible Security, to the extent
outstanding  immediately  prior to such  expiration or  termination,  never been
issued.

                  (vii)  Calculation of  Consideration  Received.  If any Common
Stock,  Option or Convertible  Security is issued or sold or deemed to have been
issued or sold for cash, the consideration  received therefor shall be deemed to
be the amount  received by the Corporation  therefor.  In case any Common Stock,
Options or Convertible  Securities are issued or sold for a consideration  other
than cash,  the amount of the  consideration  other  than cash  received  by the
Corporation  shall be the fair value of such  consideration,  except  where such
consideration consists of securities,  in which case the amount of consideration
received by the Corporation  shall be the Market Price thereof as of the date of
receipt.  If any Common Stock,  Option or Convertible  Security is issued to the
owners of the  non-surviving  entity in connection  with any merger in which the
Corporation is the surviving  corporation,  the amount of consideration therefor
shall be deemed to be the fair value of such  portion of the assets and business
of the non-surviving  entity as is attributable to such Common Stock, Options or
Convertible Securities,  as the case may be. The fair value of any consideration
other than cash and securities shall be as determined in good faith by the Board
of Directors of the Corporation.

                  (viii) Integrated  Transactions.  In case any Option is issued
in connection  with the issue or sale of other  securities  of the  Corporation,
together   comprising   one   integrated   transaction   in  which  no  specific
consideration  is  allocated to such Option by the parties  thereto,  the Option
shall be deemed to have been issued for a consideration of $.01.

                  (ix) Treasury Shares.  For purposes of calculating  under this
paragraph 5F the number of shares of Common Stock outstanding at any given time,
the number of shares of Common Stock  outstanding  at such time does not include
shares owned or held by or for the account of the  Corporation or any subsidiary
thereof,  and the disposition of any shares so owned or held shall be considered
an issue or sale of Common Stock.

                  (x)  De  Minimis   Adjustments.   Notwithstanding   any  other
provisions of this Section 5, the Corporation shall not be required to make any

<PAGE>



adjustment  of the  Conversion  Price unless such  adjustment  would  require an
increase or decrease of at least one  percent  (1%) in the  Conversion  Price as
then in effect. Any lesser adjustment shall be carried forward and shall be made
no later than the time of, and together  with,  the next  subsequent  adjustment
which,  together with any adjustment or adjustments  so carried  forward,  shall
amount to an increase or decrease of at least one percent (1%) of the Conversion
Price  as  then  in  effect.  If any  action  would  require  adjustment  of the
Conversion  Price pursuant to more than one  subparagraph  of this paragraph 5F,
only one  adjustment  shall be made as  determined in good faith by the Board of
Directors of the Corporation.

                  Section 6.        Liquidating Dividends.

                  If the  Corporation  declares or pays a  Liquidating  Dividend
upon the  Common  Stock,  then  the  Corporation  shall  pay to the  holders  of
Preferred Stock at the time of payment  thereof the  Liquidating  Dividend which
would have been paid to such  holders had such  Preferred  Stock been  converted
immediately  prior to the record  date fixed for  determining  the  stockholders
entitled to receive payment of such Liquidating Dividend,  or, if no record date
is fixed,  the date as of which the record  holders of Common Stock  entitled to
such dividends are to be determined.

                  Section 7.        Purchase Rights.

                  If at any time the  Corporation  grants,  issues  or sells any
Purchase  Rights  pro rata to the record  holders of any class of Common  Stock,
then each holder of Preferred Stock shall be entitled to acquire, upon the terms
applicable to such Purchase  Rights,  the aggregate  Purchase  Rights which such
holder  would  have  acquired  if such  holder  had held the number of shares of
Common Stock  acquirable  upon  conversion  of such  holder's  Preferred  Shares
immediately  before the date on which a record is taken for the grant,  issuance
or sale of such Purchase Rights,  or, if no such record is taken, the date as of
which the record  holders of Common  Stock are to be  determined  for the grant,
issue or sale of such Purchase Rights.

                  Section 8.        Registration of Transfer.

                  The Corporation  shall keep at its principal office a register
for the  registration  of issuances and transfers of Preferred  Stock.  Upon the
surrender of any certificate  representing  Preferred  Stock at such place,  the
Corporation  shall,  at the  request of the record  holder of such  certificate,
execute  and  deliver  (at  the  Corporation's  expense)  a new  certificate  or
certificates  in exchange  therefor  representing in the aggregate the number of
Preferred  Shares  represented  by the  surrendered  certificate.  Each such new
certificate  shall be registered in such name and shall represent such number of
Preferred  Shares as is requested by the holder of the  surrendered  certificate
and shall be substantially identical in form to the surrendered certificate, and
dividends shall accrue on the Preferred Stock

<PAGE>



represented by such new  certificate  from the date to which dividends have been
fully paid on such Preferred Stock represented by the surrendered certificate.

                  Section 9.        Replacement.

                  Upon  receipt  of  evidence  reasonably  satisfactory  to  the
Corporation (an affidavit of the registered holder shall be satisfactory) of the
ownership and the loss,  theft,  destruction  or  mutilation of any  certificate
evidencing  Preferred  Shares,  and in the  case  of any  such  loss,  theft  or
destruction,   upon  receipt  of  indemnity   reasonably   satisfactory  to  the
Corporation  (provided  that if the holder is a financial  institution  or other
institutional  investor,  its own agreement shall be  satisfactory),  or, in the
case of any such mutilation upon surrender of such certificate,  the Corporation
shall (at its  expense)  execute and deliver in lieu of such  certificate  a new
certificate of like kind representing the number of Preferred Shares represented
by such lost, stolen,  destroyed or mutilated  certificate and dated the date of
such lost,  stolen,  destroyed or mutilated  certificate,  and  dividends  shall
accrue on the Preferred Stock  represented by such new certificate from the date
to which dividends have been fully paid on the Preferred  Shares  represented by
such lost, stolen, destroyed or mutilated certificate.
