<PAGE>   2


                        Shares of Preferred Stock may be issued from time to
                time in one or more series, each of such series to have such
                terms as stated in the resolution or resolutions providing for
                the establishment of such series adopted by the Board of
                Directors of the Corporation as hereinafter provided. Except
                with respect to the Series G Preferred Stock which is described
                below, authority is hereby expressly granted to the Board of
                Directors of the Corporation to issue, from time to time, shares
                of Preferred Stock in one or more series, and, in connection
                with the establishment of any such series by resolution or
                resolutions, to determine and fix such voting powers, full or
                limited, or no voting powers, and such other powers,
                designations, preferences and relative, participating, optional,
                and other special rights, and the qualifications, limitations,
                and restrictions thereof, if any including, without limitation,
                dividend rights, conversion rights, redemption privileges and
                liquidation preferences, as shall be stated in such resolution
                or resolutions, all to the fullest extent permitted by the
                General Corporation Law of the State of Delaware. Without
                limiting the generality of the foregoing, the resolution or
                resolutions providing for the establishment of any series of
                Preferred Stock may, to the extent permitted by law, provide
                that such series shall be superior to, rank equally with or be
                junior to the Preferred Stock of any other series. Except as
                otherwise expressly provided in the resolution or resolutions
                providing for the establishment of any series of any series of
                Preferred Stock, no vote of the holders of shares of Preferred
                Stock or Common Stock shall be a prerequisite to the issuance of
                any shares of any series of the Preferred Stock authorized by
                and complying with the conditions of this Amended and Restated
                Certificate of Incorporation. The rights, preferences,
                privileges and restrictions of the Series G Preferred Stock and
                the holders thereof shall be as follows:

      1.    Dividend Provisions. The holders of shares of Series G Preferred
Stock shall be entitled to receive dividends, out of any assets legally
available therefor, prior and in preference to any declaration or payment of any
dividend (payable other than in Common Stock of the Corporation) on the Common
Stock of the Corporation, at the rate of $0.64 per share per annum, payable
quarterly, when, as and if declared by the Board of Directors. Dividends payable
on the Series G Preferred Stock and any other class or series of stock ranking
on a parity as to dividends with the Series G Preferred Stock shall be payable
on a pari passu basis in accordance with the following sentence. All dividends
declared, paid or set apart with respect to the Series G Preferred Stock and any
other class or series of stock ranking on a parity as to dividends with such
Series G Preferred Stock shall be declared, paid or set apart ratably on a
proportionate basis, based on the respective annual dividend rates fixed
therefor. All payments due under this Section 1 shall be made to the nearest
cent. Dividends on the Series G Preferred Stock shall not be cumulative.

      2.    Liquidation Preference.

            (a)   In the event of any liquidation, dissolution or winding up of
the Corporation, either voluntary or involuntary (a "Liquidation Event"), the
holders of Series G Preferred Stock shall be entitled to receive, prior and in
preference to any distribution of any of the assets of the Corporation to the
holders of Common Stock, by reason of their ownership thereof, an amount per
share equal to the sum of (i) the Liquidation Price (as hereinafter defined) for
each outstanding share of Series G Preferred Stock, and (ii) an amount equal to
all declared but unpaid dividends on each such share. With respect to any
Liquidation Event, the Series G Preferred Stock




                                        2

<PAGE>   3
shall rank on a parity with each other and shall all rank prior to the Common
Stock. If upon the occurrence of a Liquidation Event the assets and funds thus
distributed among the holders of the Series G Preferred Stock shall be
insufficient to permit the payment to such holders of the full aforesaid
preferential amounts, then the entire assets and funds of the corporation
legally available for distribution shall be distributed ratably among the
holders of the Series G Preferred Stock, based upon the respective amounts which
would be payable in respect of the shares held by them upon such distribution if
all amounts payable on or with respect to such shares were paid in full. As used
herein, the term "Liquidation Price" shall mean $8.00 for each outstanding share
of Series G Preferred Stock.

            (b)   After the distribution of all amounts due to the holders of
Series G Preferred Stock above has been paid, the remaining assets of the
Corporation available for distribution to stockholders shall be distributed
among the holders of Common Stock pro rata based on the number of shares of
Common Stock held by each.

      3.    Conversion. The holders of Series G Preferred Stock shall have the
following conversion rights (the "Conversion Rights"):

            (a)   Right to Convert. Each share of Series G Preferred Stock shall
be convertible, at the option of the holder thereof, at any time nine months
after the date of issuance of such share, at the office of the Corporation or
any transfer agent for the Series G Preferred Stock, into one (1) share of
Common Stock, subject to adjustment as set forth in subsection 3(c).

            (b)   Mechanics of Conversion. The holder of any shares of Series G
Preferred Stock may exercise the conversion right provided in subsection 3(a) as
to any shares thereof by delivering to the Corporation the certificate or
certificates therefor, duly endorsed, at the office of the Corporation, and such
holder shall give written notice to the Corporation of the election to convert
the same and shall state therein the name or names in which the certificate or
certificates for shares of Common Stock are to be issued. Conversion shall be
deemed to have been effected on the date when the aforesaid delivery is made,
and such date is hereinafter referred to as the "Conversion Date." As promptly
as practicable thereafter, the Corporation shall issue and deliver to or upon
the written order of such holder, to the place designated by such holder, a
certificate or certificates for the number of full shares of Common Stock to
which such holder is entitled. The person in whose names the certificate or
certificates for Common Stock are to be issued shall be deemed to have become a
stockholder of record on the applicable Conversion Date unless the transfer
books of the Corporation are closed on that date, in which event he shall be
deemed to have become a stockholder of record on the next succeeding date on
which the transfer books are open. Upon conversion of only a portion of the
number of shares covered by a certificate representing shares of Series G
Preferred Stock surrendered for conversion, the Corporation shall


                                       3
<PAGE>   4
issue and deliver to or upon the written order of the holder of the certificate
so surrendered for conversion, at the expense of the Corporation, a new
certificate covering the number of shares of Series G Preferred Stock
representing the unconverted portion of the certificate so surrendered, which
new certificate shall entitle the holder thereof to dividends on the shares of
Series G Preferred Stock represented thereby to the same extent as if the
certificate theretofore covering such unconverted shares had not been
surrendered for conversion.

            (c)   Adjustments to Conversion Ratio. The ratio for the conversion
of Series G Preferred Stock into Common Stock (the "Conversion Ratio") shall be
subject to adjustment from time to time as follows:

                  (i)   In the event the Corporation should at any time or from
time to time after the issuance of the Series G Preferred Stock fix a record
date for the effectuation of a split or subdivision of the outstanding shares of
Common Stock or the determination of holders of Common Stock entitled to receive
a dividend or other distribution payable in additional shares of Common Stock
without payment of any consideration by such holder for the additional shares of
Common Stock, then, as of such record date (or the date of such dividend,
distribution, split or subdivision, if no record date is fixed), the Conversion
Ratio shall be appropriately adjusted so that the number of shares of Common
Stock issuable on conversion of each share of the Series G Preferred Stock shall
be increased in proportion to such increase of outstanding shares.

                  (ii)  If the number of shares of Common Stock outstanding at
any time after the issuance of the Series G Preferred Stock is decreased by a
combination of the outstanding shares of Common Stock, then, following the
record date of such combination, the Conversion Ratio shall be appropriately
adjusted so that the number of shares of Common Stock issuable on conversion of
each share of such Series G Preferred Stock shall be decreased in proportion to
such decrease in outstanding shares.

            (d)   Other Distributions. In the event the Corporation shall
declare a distribution payable in securities of other persons, evidences of
indebtedness issued by the Corporation or other persons, or assets (excluding
cash dividends), then, in each such case for the purpose of this subsection
3(d), the holder of Series G Preferred Stock shall be entitled to a
proportionate share of any such distribution as though they were the holders of
the number of shares of Common Stock of the Corporation into which their shares
of Series G Preferred Stock are convertible as of the record date fixed for the
determination of the holders of Common Stock of the Corporation entitled to
receive such distribution.

            (e)   Recapitalization. If, at any time or from time to time there
shall be a recapitalization of the Common Stock (other then a subdivision,
combination or merger or sale of assets transaction provided for elsewhere in
this Section 3 or in Section 4), provisions shall be made so that the holders of
Series G Preferred Stock shall thereafter be entitled to receive upon conversion
of their Preferred Stock the number of shares of stock or other securities or
property of


                                       4
<PAGE>   5
the Corporation or otherwise, to which a holder of Common Stock deliverable upon
conversion would have been entitled on such recapitalization. In any such case,
appropriate adjustment shall be made in the application of the provisions of
this Section 3 with respect to the rights of the holders of Series G Preferred
Stock after the recapitalization to the end that the provisions of this Section
3 (including adjustment of the Series G Conversion Price then in effect and the
number of shares purchasable upon conversion of Series G Preferred Stock) shall
be applicable after the event as nearly equivalent as may be practicable.

            (f)   No Impairment. The Corporation will not, by amendment of its
Restated Certificate of Incorporation or through any reorganization,
recapitalization, transfer of assets, consolidation, merger, dissolution, issue
or sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Corporation, but will at all times in good faith assist in the
carrying out of all the provisions of this Section 3 and in the taking of all
such action as may be necessary or appropriate in order to protect the
Conversion Rights of the holders of the Series G Preferred Stock against
impairment.

            (g)   No Fractional Shares and Certificates as to Adjustments. (i)
No fractional shares shall be issued upon conversion of the Series G Preferred
Stock and the number of shares of Common Stock to be issued shall be rounded to
the nearest whole share.

                  (ii)  Upon the occurrence of each adjustment or readjustment
of the Conversion Ratio pursuant to this Section 3, the Corporation, at its
expense, shall promptly compute such adjustment or readjustment in accordance
with the terms hereof and prepare and furnish to each holder of Series G
Preferred Stock a certificate setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any holder of
Series G Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (A) such adjustment and readjustment, (B) the
Conversion Ratio at the time in effect, and (C) the number of shares of Common
Stock and the amount, if any, of other property which at the time would be
received upon the conversion of a share of Series G Preferred Stock.

                  (iii) If any adjustment in the number of shares of Common
Stock into which each share of Series G Preferred Stock may be converted
required pursuant to this Section 3 would result in an increase or decrease of
less than 1% in the number of shares of Common Stock into which each share of
Series G Preferred Stock is then convertible, the amount of any such adjustment
shall be carried forward and adjustment with respect thereto shall be made at
the time of and together with any subsequent adjustment which, together with
such amount and any other amount or amounts so carried forward, shall aggregate
at least 1% of the number of shares of Common Stock into which each share of
Series G Preferred Stock is then convertible. All calculations under this
paragraph (iii) shall be made to the nearest one-hundredth of a share.


                                       5
<PAGE>   6
            (h)   Notices of Record Date. In the event of any taking by the
Corporation of a record of the holders of any class of securities for the
purpose of determining the holders thereof who are entitled to receive any
dividend (other than a cash dividend) or other distribution, the Corporation
shall mail to each holder of Series G Preferred Stock, at least 20 days prior to
the date specified therein, notice for specifying the date on which any such
record is to be taken for the purpose of such dividend or distribution.

            (i)   Reservation of Stock Issuable Upon Conversion. 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 effecting the conversion of the
shares of Series G Preferred Stock such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of Series G Preferred Stock; and, if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of Series G Preferred
Stock, in addition to such other remedies as shall be available to the holder of
such Series G Preferred Stock, the Corporation will take such corporate action
as may, in the opinion of its counsel, be necessary to increase its authorized
but unissued shares of Common Stock to such number of shares as shall be
sufficient for such purposes.

            (j)   Notices. Any notice required by the provisions of this Section
3 to be given to the holders of shares of Series G Preferred Stock shall be
deemed given if deposited in the United States mail, postage prepaid, and
addressed to each holder of record at his address appearing on the books of the
Corporation.

      4.    Merger, Consolidation. If at any time there is a merger or
consolidation of the Corporation with or into another corporation or other
entity or person, or any other corporate reorganization, in which the
Corporation shall not be the continuing or surviving entity of such merger,
consolidation or reorganization, or the sale of all or substantially all of the
Corporation's properties and assets to any other person, then, as a part of such
reorganization, merger, consolidation or sale, provision shall be made so that
the holders of the Series G Preferred Stock shall be entitled to receive (on a
per share basis), prior to any distribution to holders of Common Stock, the
number of shares of stock or other securities or property to be issued to the
Corporation or its stockholders resulting from such reorganization, merger,
consolidation or sale in an amount per share equal to the applicable Liquidation
Price for the Series G Preferred Stock plus a further amount equal to any
dividends declared but unpaid on such shares.

      5.    Voting Rights. The holder of each share of Series G Preferred Stock
shall have the right to one vote for each share of Common Stock into which such


                                       6
<PAGE>   7
Series G Preferred Stock could then be converted or could be converted without
regard to the limitation on conversions set forth at Subsection 3(a) (with any
fractional share determined on an aggregate conversion basis being rounded to
the nearest whole share), and with respect to such vote, such holder shall have
full voting rights and powers equal to the voting rights and powers of the
holders of Common Stock, and shall be entitled, notwithstanding any provision
hereof, to notice of any stockholders' meeting in accordance with the Bylaws of
the Corporation, and shall be entitled to vote, together with holders of Common
Stock, with respect to any question upon which holders of Common Stock, have the
right to vote, in the same manner and with the same effect as such holders of
Common Stock, as one class.

      6.    Status of Converted or Redeemed Stock. In the event any shares of
Series G Preferred Stock shall be converted pursuant to Section 3, the shares so
converted shall be canceled and shall not be issuable by the Corporation.

      7.    Preemptive Rights. The holders of Series G Preferred Stock shall not
have any preemptive rights.

                FIFTH: (1) The business and affairs of the Corporation shall be
                managed by or under the direction of a Board of Directors
                consisting of not less than 3 nor more than 11 directors, the
                exact number of directors to be determined from time to time
                solely by resolution adopted by the affirmative vote of a
                majority of the entire Board of Directors.

                        (2) The directors of the Corporation, other than
                directors elected by one or more series of Preferred Stock,
                shall be divided into three classes, designated Class I, Class
                II and Class III. Each class shall consist, as nearly as may be
                possible, of one-third of the total number of directors (other
                than directors elected by one or more series of Preferred Stock)
                constituting the entire Board of Directors. Each director (other
                than directors elected by one or more series of Preferred Stock)
                shall serve for a term ending on the date of the third annual
                meeting of stockholders next following the annual meeting at
                which such director was elected, provided that directors
                initially designated as Class I directors shall serve for a term
                ending on the date of the 1998 annual meeting, directors
                initially designated as Class II directors shall serve for a
                term ending on the date of the 1999 annual meeting, and
                directors initially designated as Class III directors shall
                serve for a term ending on the date of the 2000 annual meeting.
                Notwithstanding the foregoing, each director shall hold office
                until such director's successor shall have been duly elected and
                qualified or until such director's earlier death, resignation or
                removal. If the number of directors (other than directors
                elected by one or more series of Preferred Stock) is changed,
                any increase or decrease shall be apportioned among the classes
                so as to maintain the number of directors in each class as
                nearly equal as possible, but in no event will a


                                       7
<PAGE>   8

                decrease in the number of directors shorten the term of any
                incumbent director. Vacancies on the Board of Directors
                resulting from death, resignation, removal or otherwise and
                newly created directorships resulting from any increase in the
                number of directors (other than directors elected by one or more
                series of Preferred Stock) may be filled solely by a majority of
                the directors then in office (although less than a quorum) or by
                a sole remaining director, and each director so elected shall
                hold office for a term that shall coincide with the remaining
                term of the class to which such director shall have been
                elected. Whenever the holders of one or more classes or series
                of Preferred Stock shall have the right, voting separately as a
                class or series, to elect directors, the nomination, election,
                term of office, filling of vacancies, removal and other features
                of such directorships shall not be governed by this ARTICLE
                FIFTH unless otherwise provided for in the certificate of
                designation for such classes or series.

                        (3) No director (other than directors elected by one or
                more series of Preferred Stock) may be removed from office by
                the stockholders except for cause and, in addition to any other
                vote required by law, upon the affirmative vote of the holders
                of two-thirds (66 2/3%) of all outstanding securities of the
                Corporation then entitled to vote generally in the election of
                directors, voting together as a single class.

                SIXTH: The Corporation is to have perpetual existence.

                SEVENTH: The following provisions are inserted for the
                management of the business and the conduct of the affairs of the
                Corporation and for the further definition of the powers of the
                Corporation and its directors and stockholders:

                        (1) The Board of Directors shall have the power to
                adopt, amend, alter, rescind or repeal the bylaws of the
                Corporation.

                        The stockholders may adopt, amend, alter, rescind or
                repeal the bylaws only with, in addition to any other vote
                required by law, the affirmative vote of the holders of not less
                than 66 2/3% of the total voting power of all outstanding
                securities of the Corporation then entitled to vote generally in
                the election of directors, voting together as a single class.

                        (2) Elections of directors need not be by written ballot
                unless the bylaws of the Corporation so provide.

                called by any other person. Notwithstanding the foregoing,
                whenever holders of one or more classes or series of Preferred

                EIGHTH: A director of this corporation shall not be liable to
                the Corporation or its stockholders for monetary damages for
                breach of fiduciary duty as a director, except to the extent
                such exemption from liability or limitation thereof is not
                permitted under the General Corporation Law of the State of
                Delaware as the same exists or may hereafter be amended. The
                Corporation shall indemnify its directors and officers to the
                fullest extent permitted under the General Corporation Law of
                the State of Delaware, including circumstances in which
                indemnification is otherwise discretionary.

                        Any repeal or modification of the foregoing paragraph
                shall not adversely affect any right or protection of a director
                of the Corporation existing hereunder with respect to any act or
                omission occurring prior to such repeal or modification.

               3. That said Amended and Restated Certificate of Incorporation
has been consented to and authorized by the holders of a majority of the issued
and outstanding stock entitled to vote by written consent given in accordance
with the provisions of Sections 242 and 245 Section 228 of the General
Corporation Law of the State of Delaware.
