                                   ARTICLE I

          The name of the corporation is GeoSystems Global Corporation (the 
"Corporation").

                                   ARTICLE II

          The address of the Corporation's registered office in the State of 
Delaware is Corporation Trust Center, 1209 Orange Street, in the City of 
Wilmington, County of New Castle. The name of its registered agent at such 
address is The Corporation Trust Company.

 
                                  ARTICLE III

          The Corporation shall have perpetual existence. The nature of the 
business or purposes to be conducted or promoted is to engage in any lawful act 
or activity for which corporations may be organized under the General 
Corporation Law of Delaware.

                                  ARTICLE IV

          This Corporation is authorized to issue two classes of stock to be
designated, respectively, "Common Stock" and "Preferred Stock." The total number
of shares which this corporation is authorized to issue is thirty-five million
(35,000,000) shares. Twenty million (20,000,000) shares shall be designated
Common Stock, par value $0.001 per share. Fifteen million (15,000,000) shares
shall be designated Preferred Stock, par value $0.01 per share, of which six
million five hundred and fifty thousand (6,550,000) shares shall be designated
Series A Preferred Stock (the "Series A Preferred"), two million (2,000,000)
shares shall be designated Series B Preferred Stock (the "Series B Preferred")
and three million eight hundred thousand (3,800,000) shares shall be designated
Series C Preferred Stock (the "Series C Preferred") and two million six hundred
and fifty thousand (2,650,000) shares shall be undesignated as to series.

          Any Preferred Stock not previously designated as to series may be
issued from time to time in one or more series pursuant to a resolution or
resolutions providing for such issue duly adopted by the Board of Directors
(authority to do so being hereby expressly vested in the Board), and such
resolution or resolutions shall also set forth the voting powers, full or
limited or none, of each such series of Preferred Stock and shall fix the
designations, preferences and relative, participating, optional or other special
rights and qualifications, limitations or restrictions of each such series of
Preferred Stock. The Board of Directors is authorized to alter the designation,
rights, preferences, privileges and restrictions granted to or imposed upon any
wholly unissued series of Preferred Stock and, within the limits and
restrictions stated in any resolution or resolutions of the Board of Directors
originally fixing the number of shares constituting any series of Preferred
Stock, to increase or decrease (but not below the number of shares of any such
series then outstanding) the number of shares of any such series subsequent to
the issue of shares of that series.

          Each share of Preferred Stock issued by the Corporation, if reacquired
by the Corporation (whether by redemption, repurchase, conversion to Common 
Stock or other means), shall upon such reacquisition resume the status of 
authorized and unissued shares of Preferred Stock, undesignated as to series 
and available for designation and issuance by the Corporation in accordance 
with the immediately preceding paragraph.

                                      -2-

 
                                   ARTICLE V

     The preferences and relative, optional and other special rights of the 
shares of Series A Preferred, and the qualifications, limitations or 
restrictions thereof, are as follows:

     1.   DESIGNATION OF SERIES: RANK. The number of shares of Series A 
          ---------------------------
Preferred may be increased or decreased, at any time and from time to time, by 
resolution of the Board of Directors: provided that no decrease shall reduce the
number of shares of Series A Preferred to a number less than that of the shares 
of such series then outstanding. The Series A Preferred shall rank senior to the
Common Stock of the Corporation and junior to the Series B Preferred and Series 
C Preferred with respect to the payment of dividends and as to (i) the 
distribution of assets upon liquidation, dissolution or winding up, and (ii) the
distribution of assets upon the redemption of the Series A Preferred, Series B 
Preferred and Series C Preferred. Subject to the protective provisions set forth
in Section 7(b) hereof, the Board of Directors may by resolution issue and 
designate additional series or classes of Preferred Stock which may rank senior 
to, junior to, or on parity with the Series A Preferred with respect to the 
payment of dividends, the distribution of assets upon liquidation, dissolution 
or winding up, redemption rights, and the other rights, preferences and 
privileges of such preferred stock.

     2.   DIVIDENDS AND DISTRIBUTIONS.  
          ---------------------------
  
          (a) Subject to the prior and superior rights of the holders of any
shares of Series B Preferred, of shares of Series C Preferred or of shares of
any other series of Preferred Stock now existing or hereafter designated ranking
senior to the shares of Series A Preferred with respect to dividends, the
holders of shares of Series A preferred, in preference to the holders of Common
Stock and any series of Preferred Stock now existing or hereafter designated
which expressly provides by its terms that it is junior to the Series A
Preferred in dividend rights, shall be entitled to receive, when and as declared
by the Board of Directors out of funds legally available therefor, an annual
cash dividend in the amount of $0.075 per share. Such dividends shall not be
cumulative, and no right shall accrue to holders of Series A Preferred by reason
of the fact that dividends on such shares are not declared or paid in any year.

          (b) Notwithstanding Section 2(a) hereof, the Board of Directors of the
Corporation may not declare, and the Corporation may not pay, any dividends on 
the shares of Series A Preferred unless (i) the Corporation has paid in cash all
dividends or interest (as the case may be) accrued and payable on the shares of 
Series B Preferred or Convertible Debt (as defined in Article VI, Section 4(a) 
hereof) (as the case may be) as of the date of the proposed dividend on the 
shares of Series A Preferred and (ii) the Corporation has paid in cash a 
dividend on each share of Series C Preferred as of the date of the proposed 
dividend on the shares of Series A Preferred in an amount equal to the original 
purchase price of the Series C Preferred multiplied by a fraction, the numerator
of which is the amount of the dividend payable on the Series A Preferred, and 
the denominator of which is the original purchase price of the Series A 
Preferred

                                      -3-
 













 
(subject to appropriate adjustment for all stock splits, stock dividends, 
combinations and recapitalizations of Series A and Series C Preferred).
         
          (c) Notwithstanding Section 2(a) hereof, the Corporation may at any
time, out of funds legally available therefor, repurchase shares of Common Stock
of the corporation (i) issued to or held by employees, directors or consultants
of the Corporation or its subsidiaries upon termination of their employment of
services, pursuant to an agreement providing for such right of repurchase, or
(ii) issued to or held by any person subject to the Corporation's right of first
refusal to purchase such shares where the purchase is pursuant to the exercise
of such right of first refusal, in either case whether or not dividends on the
Series A Preferred shall have been declared and paid or funds set aside
therefor.

     3.   VOTING RIGHTS. Except as otherwise required by law, each share of 
          -------------
Series A Preferred issued and outstanding shall at any time have a number of 
votes equal to the number of shares of Common Stock into which such share of 
Series A Preferred is then convertible pursuant to Section 5 hereof. Subject to 
the foregoing, the holders of Series A Preferred shall be entitled to vote with 
the holders of Common Stock on all matters submitted to a vote of stockholders 
(whether at a meeting or by written consent); provided that, subject to Section
1 hereof, the Series A Preferred shall be entitled to vote as a separate series
(the affirmative vote or consent of the holders of at least a majority of the
outstanding shares of such separate series being required) or as part of a class
(together with other series of Preferred Stock) on any matter with respect to
which a series vote by the Series A Preferred or a class vote of the Preferred
Stock, as the case may be, shall be expressly required by law, and any such
class or series vote may be given in person or by proxy, either in writing
without a meeting or by vote at any meeting called for the purpose.

     4.   LIQUIDATION.  Subject to the prior and superior rights of the holders 
          -----------
of any shares of Series B Preferred, of shares of Series C Preferred and of
shares of any other series of Preferred Stock now existing or hereafter
designated ranking senior to the shares of Series A Preferred with respect to
liquidation preference, in the event of any voluntary or involuntary
dissolution, liquidation or winding up of the Corporation (for the purposes of
this Section 4, a "LIQUIDATION"), before any distribution of assets shall be
made to the holders of the Common Stock or the holders of any other stock now
existing or hereafter designated that by its express terms ranks junior to the
Series A Preferred in respect of distributions upon the Liquidation of the
Corporation, the holder of each share of Series A Preferred then outstanding
shall be entitled to be paid out of the assets of the Corporation available for
distribution to its stockholders an amount in cash equal to $1.00 per share plus
all dividends declared and unpaid on such share on the date fixed for the
distribution of assets of the Corporation in liquidation to the holders of
Series A Preferred.

     If upon any Liquidation the aggregate assets available for distribution to 
the holders of the Series A Preferred and any other stock of the Corporation now
existing or hereafter designated ranking on parity with the Series A Preferred 
upon Liquidation and which shall then be

                                      -4-

 
outstanding (hereinafter in this paragraph called the "TOTAL AMOUNT AVAILABLE") 
shall be insufficient to pay the holders of all outstanding shares of Series A 
Preferred and all such other parity stock the full amounts (including all 
dividends accrued and unpaid) to which they shall be entitled by reason of such 
Liquidation of the Corporation, then there shall be paid to the holder of each 
share of Series A Preferred in connection with such Liquidation an amount equal 
to the product derived by multiplying the Total Amount Available times a 
fraction, the numerator of which shall be the full amount to which such share of
Series A Preferred shall be entitled under the terms of the preceding paragraph 
by reason of such Liquidation and the denominator of which shall be the total 
amount which would have been distributed by reason of such Liquidation with 
respect to all Series A Preferred and other stock ranking on a parity with the 
Series A Preferred then outstanding upon a Liquidation had the Corporation 
possessed sufficient assets to pay the maximum amount which the holders of all 
such stock would be entitled to receive in connection with such Liquidation.

     The voluntary sale, conveyance, lease, exchange or transfer of all or 
substantially all the property or assets of the Corporation, or the merger or 
consolidation of the Corporation into or with any other corporation, or the 
merger of any other corporation into the Corporation, or any purchase or 
redemption of some or all of the shares of any class or series of stock of the 
Corporation, shall not be deemed to be a Liquidation of the Corporation for the 
purposes of this Section 4.

     The holder of any shares of Series A Preferred shall not be entitled to 
receive any payment owed for such shares under this Section 4 until such holder 
shall cause to be delivered to the Corporation (i) the certificate(s) 
representing such shares and (ii) transfer instrument(s) satisfactory to the 
Corporation and sufficient to surrender such shares to the Corporation free of 
any adverse interest.

     After payment of the full amount of the liquidating distribution to which 
any holder of Series A Preferred is entitled, the holder of such share or shares
will not be entitled to any further participation in any distribution of assets 
by the Corporation.

     5.   CONVERSION RIGHTS.
          -----------------

          (a)   Optional Conversion into Common Stock. The holder of any share
                ------------------------------------- 
of Series A Preferred shall have the right, at such holder's option, at any time
to convert such share into that number of shares of fully paid and nonassessable
whole shares of Common obtained by dividing $1.00 by the Series A Conversion 
Price then in effect. The Series A Conversion Price shall initially be $1.00 per
share, and shall be subject to adjustment as set forth below.


          (b)  Automatic Conversion. Each share of Series A Preferred shall
               -------------------- 
automatically convert into shares of fully paid and nonassessable Common Stock, 
without any further action required on the part of the holder thereof, either 
(i) immediately prior to the closing of the Corporation's initial underwritten 
public offering pursuant to a Registration Statement filed with

                                      -5-

 
and declared effective by the Securities and Exchange Commission under the
Securities Act of 1933, as amended, and having an aggregate offering price to
the public of not less than $15,000,000 (a "Qualified Public Offering") or (ii)
upon the affirmative vote of the holders of at least two-thirds (2/3) of the
then outstanding shares of Series A Preferred, whichever is earlier. The number
of shares of Common Stock issuable upon such automatic conversion of any such
share shall be equal to the number obtained by dividing $1.00 by the Series A
Conversion Price then in effect.

          (c) Procedure for Conversion. To exercise the conversion privilege set
              ------------------------
forth in Section 5(a) hereof, the holder of shares of Series A Preferred shall
surrender the shares to be converted, accompanied by instruments of transfer
satisfactory to the Corporation and sufficient to transfer the shares being
converted to the Corporation free of any adverse interest, at the principal
offices of the Corporation or any of the offices or agencies maintained for such
purpose by the Corporation ("Conversion Agent") and shall give written notice
(by registered or certified mail, overnight courier or hand delivery) to the
Corporation at such Conversion Agent that the holder elects to convert such
shares. Such notice shall state whether and to what extent the shares so
surrendered for conversion shall be converted into shares of Common Stock, and
shall also state the name or names, together with address or addresses, in which
the certificate or certificates for Common Stock issuable on such conversion
shall be issued. As promptly as practicable after the surrender of such shares
of Series A Preferred as aforesaid, the Corporation shall issue and deliver at
such Conversion Agent to such holder, or on such holder's written order, a
certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion of such shares in accordance with the provisions
hereof. Certificates will be issued for the balance of the shares of Series A
Preferred in any case in which fewer than all of the shares of Series A
Preferred are converted.

          Each conversion pursuant to Section 5(a) hereof shall be deemed to
have been effected immediately prior to the close of business on the date on
which the shares of Series A Preferred shall have been so surrendered and such
notice shall have been received by the Corporation as aforesaid. Each conversion
pursuant to Section 5(b) hereof shall be deemed to have been effected,
automatically and with no further required action on die part of the holder of
the shares as converted, immediately prior to (but contingent upon) the closing
of the sale of shares pursuant to the Qualified Public Offering. In each such
case, the person or persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder or holders of record of the Common
Stock represented thereby at the effective date of such conversion, unless the
stock transfer books of the Corporation shall be closed on such date, in which
event such conversion shall be deemed to have been effected immediately prior to
the open of business on the next succeeding day on which such stock transfer
books are open, and such person or persons shall be deemed to have become such
holder or holders of record of the Common Stock at the open of business on such
later day. In each such case, the conversion shall be at the Conversion Price in
effect on the effective date of the conversion as determined above. No payment
or adjustment shall be made on conversion for any dividends payable on the
Common Stock delivered on

                                      -6-



 
conversion. Effective as of any such conversion, the Corporation shall be 
excused from paying any dividends on the shares converted, except for any 
dividends accrued (whether or not earned or declared) and unpaid through the day
of conversion.

     No fractional interest in a share of Common Stock shall be deliverable upon
the conversion of any share or shares of Series A Preferred, and the number of 
shares of Common Stock issuable upon any such conversion shall be rounded down 
to the nearest whole share. If more than one certificate representing shares of 
Series A Preferred is to be converted at one time by the same holder into Common
Stock, the number of full shares of Common Stock issuable upon conversion 
thereof shall be computed on the basis of the aggregate number of shares of 
Series A Preferred represented by such certificates, or the specified portions 
thereof to be converted.

          (d)  Adjustment of Conversion Price.  The Conversion Price shall be 
               ------------------------------
adjusted from time to time in respect of any of the following events occurring 
on or after the date upon which a share of Series A Preferred is first issued 
(the "ORIGINAL ISSUE DATE" of the Series A Preferred), as follows:

               (i)  Dividends and Distributions. In case the Corporation shall
                    ---------------------------
pay or make a dividend or other distribution upon its Common Stock payable in
Common Stock, the Conversion Price in effect at the opening of business on the
day following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be reduced by multiplying
such Conversion Price by a fraction, of which the numerator shall be the number
of shares of Common Stock outstanding at the close of business on the date fixed
for such determination and the denominator shall be the sum of such number of 
shares and the total number of shares constituting such dividend or other 
distribution, such reduction to become effective immediately after the opening 
of business on the day following the date fixed for such determination. For the 
purposes of this paragraph (i), the number of shares of Common Stock at any time
outstanding shall not include shares held in the treasury of the Corporation. 
The Corporation will not pay any dividend or make any distribution on shares of 
Common Stock held in the treasury of the Corporation.


               (ii) Subdivisions and Combinations. In case the outstanding 
                    -----------------------------
shares of Common Stock shall each be subdivided into a greater number of shares 
of Common Stock (other than any such subdivision which is effected pursuant to a
dividend or distribution for which adjustment to the Conversion Price is made 
under paragraph (i) above), the Conversion Price in effect at the opening of 
business on the day following the day upon which such subdivision becomes 
effective shall be proportionately reduced and, conversely, in case the 
outstanding shares of Common Stock shall each be combined into a smaller number 
of shares of Common Stock, the Conversion Price in effect at the opening of 
business on the day following the day upon which such combination becomes 
effective shall be proportionately increased, such reduction or increase, as the
case may be, to become effective immediately after the opening of business on 
the day following the day upon which such subdivision or combination becomes 
effective.

                                      -7-

 
               (iii)  Distributions other than Cash Dividends. In case the
                      ---------------------------------------   
Corporation shall declare a cash dividend upon its Common Stock payable
otherwise than out of retained earnings or shall distribute to holders of its
Common Stock shares of its capital stock (other than Common Stock), stock or
other securities of other persons, evidences of indebtedness issued by the
Corporation or other persons, assets (excluding cash dividends out of retained
earnings) or options or rights (excluding options to purchase and rights to
subscribe for Common Stock or other securities of the Corporation convertible
into or exchangeable for Common Stock), then, in each such case, the holders of
shares of Series A Preferred shall, concurrently with the distribution to
holders of Common Stock, receive a like distribution based upon the number of
shares of Common Stock into which such shares of Series A Preferred shall then
be convertible.

               (iv)   Reclassifications.  In case of any capital reorganization 
                      -----------------
or reclassification of the stock of the Corporation (other than any transaction
described in paragraph (i), (ii) or (iii) hereof), of the consolidation or
merger of the Corporation with or into another person (other than a
consolidation or merger in which the Corporation is the continuing entity and
which does not result in any change in the Common Stock), the shares of the
Series A Preferred shall, after such reorganization, reclassification,
consolidation or merger, be convertible into the kind and number of shares of
stock or other securities or property of the Corporation or otherwise to which
the holder thereof would have been entitled if immediately prior to such
reorganization, reclassification, consolidation, or merger the holder had
converted the holder's shares of the Series A Preferred into Common Stock.

               (v)    Tax Adjustments.  The Corporation may in its sole 
                      ---------------
discretion make such reductions in the Conversion Price, in addition to those 
required by paragraphs (i), (ii), (iii) and (iv) above, as it considers to be 
advisable in order that any event treated for Federal income tax purposes as a 
dividend of stock or stock rights shall not be taxable to the recipient.

               (vi)   Reservation of Shares.  the Corporation shall at all times
                      ---------------------
reserve and keep available, free from preemptive fights, out of its authorized
but unissued Common Stock, for the purpose of issuance upon conversion of the
Series A Preferred, the maximum number of shares of Common Stock then
deliverable upon the conversion of all shares of Series A Preferred then
outstanding. All common Stock issued upon conversion of the Series A Preferred
shall be newly issued and, when issued, shall be duly authorized, validly
issued, fully paid and nonassessable, and free and clear of any liens or
encumbrances.

     6.   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, any right to subscribe for,
purchase or otherwise acquire any shares of stock of any class or any other
securities or property, or to receive any other right, the Corporation shall
mail to each holder of Series A Preferred, at least fifteen (15) days prior to
the date specified therein, a notice specifying the date on which any such
record is to be taken for the purpose of such dividend, distribution or right,
and the amount and character of such dividend, distribution or right.

                                      -8-
     

 
     7.   PROTECTIVE PROVISIONS.  So long as any shares of Series A Preferred 
          ---------------------
are outstanding, this Corporation shall not, without first obtaining the 
approval (by vote or written consent, as provided by law) of the holders of at 
least a majority of the then outstanding shares of Series A Preferred voting 
together as a class:

          (a)  amend or repeal any provision of, or add any provision to, this 
Corporation's Restated Certificate of Incorporation if such action would 
adversely alter or change the preferences, rights, privileges or powers of, or 
the restrictions provided for the benefit of, the Series A Preferred; or

          (b)  authorize or issue shares of any class of stock (other than the 
Series B Preferred issued as dividends as described in Article VI hereof) having
any preference or priority as to dividend, redemption or liquidation preferences
which is superior to any such preference or priority of the Series A Preferred.

     8.   REDEMPTION RIGHTS.
          -----------------

          (a)  Holder Redemption.  Subject to the prior and superior rights of 
               -----------------
the holders of the shares of Series B Preferred and shares of Series C
Preferred, upon written notice at least one hundred twenty (120) days prior to
December 31 of any calendar year from, and including, the year 2002, by the
holders of at least two-thirds (2/3) of the then outstanding shares of Series A
Preferred (a "Holder Election"), the Corporation shall be required to redeem all
of the issued, outstanding and nonredeemed shares of Series A Preferred held by
each holder of Series A Preferred (a "Holder Redemption"), at a redemption price
per share (the "Redemption Price") of $1.00 plus an amount equal to all declared
but unpaid dividends on the Series A Preferred. In the event of any such Holder
Election, the Corporation shall, out of and only to the extent of funds legally
available therefor, redeem (i) on the December 31 following such Holder
Election, one-third of the number of shares of Series A Preferred then issued
and outstanding; (ii) on the second December 31 following such Holder Election,
one-half of the number of shares of Series A Preferred then issued and
outstanding; and (iii) on the third December 31 following such Holder Election,
all of the shares of Series A Preferred then issues and outstanding. the
Redemption Price payable upon any Holder Redemption shall be paid in cash, to
the extent of funds legally available therefor.

          (b)  In the event that the Corporation does no have legally available 
funds sufficient to pay in full the Redemption Price with respect to each share 
of Series A Preferred being redeemed pursuant to this Section 8 ("REDEEMED 
SHARES"), the corporation shall redeem the shares of Series A Preferred 
otherwise scheduled for redemption pro rata among the holders of the Series A 
Preferred then outstanding, based on the number of shares then held by each 
holder of Series A Preferred.

          (c)  Payment of Redemption Price.  In the case of any Holder 
               ---------------------------
Redemption pursuant to Section 4(a), the Corporation shall pay the Redemption 
Price in cash.

                                      -9-

 
          (d)  Mechanics of Redemption.
               -----------------------

               (i)   Notice of any Holder Redemption of the Series A Preferred 
shall be mailed at least thirty (30), but not more than sixty (60), calendar 
days prior to each December 31 redemption date (each, a "Holder Redemption 
Date"), to each holder of Series A Preferred to be redeemed at such holder's
address as it appears on the books of the Corporation.  To facilitate the 
redemption of the Series A Preferred, the Board of Directors may fix a record 
date for the determination of the holders of shares of Series A Preferred to be
redeemed on each Holder Redemption Date, which date shall be not more than sixty
(60), nor less than ten (10) calendar days prior to the respective Holder
Redemption Date.

               (ii)  The holder of any shares of Series A Preferred redeemed 
pursuant to this Section 8 shall not be entitled to receive payment of the 
Redemption Price for such shares until such holder shall cause to be delivered 
to the place specified in the Corporation's notice of redemption (i) the 
certificates representing the shares of Series A Preferred to be redeemed and 
(ii) appropriate endorsements and transfer documents sufficient to transfer such
shares of Series A Preferred to the Corporation free of any adverse interest.  
In the event the redemption amount payable on any redeemed share of Series A 
Preferred is not paid in full within fifteen (15) business days after the Holder
Redemption Date as provided herein, then the unpaid portion of the Redemption 
Price of such share shall bear interest at a rate of 12% per annum, commencing 
at the close of business on the Holder Redemption Date and continuing until the 
redemption price on such share is paid in full.  Interest shall be computed on 
the basis of a three hundred sixty-five (365) day year and shall be payable on 
demand.

               (iii) In the event of any redemption, then upon the Holder 
Redemption Date and if all funds necessary for such redemption shall have been 
paid in cash or set aside by the Corporation separate and apart from its other 
funds in trust for the pro rata benefit of the holders of the shares called for 
redemption, so as to be and continue to be available therefor, then the shares
so called for redemption shall no longer be deemed outstanding, the rights to
receive dividends thereon shall cease to accrue from and after the applicable
Holder Redemption Date, and all rights of the holders of the shares of Series A
Preferred called for redemption shall cease and terminate, excepting only the
right to receive the Redemption Price therefor (including any accrued and unpaid
dividends, whether or not earned or declared, to the Holder Redemption Date if
such price has not already been paid, without interest except as provided in
Section 4(d)(ii) hereof.

          (e)  Conversion Rights.  Nothing contained in this Section 8 shall in 
               -----------------
any way restrict or prohibit the holders of the Series A Preferred from 
exercising their conversion rights pursuant to Section 5 hereof prior to the 
redemption of any shares hereunder.

          (f)  Priority on Redemption. The redemption rights of the shares of
               ----------------------
Series A Preferred are subject to the prior and superior rights of the holders
of any shares of Series B Preferred and Series C Preferred. Accordingly, if on
any applicable Holder Redemption Date,

                                     -10-



 
any shares of Series B Preferred or Series C Preferred remain outstanding, the 
holders of the Series B Preferred and Series C Preferred shall be entitled to 
have all of their shares redeemed prior to the redemption of any shares of 
Series A Preferred. Upon its receipt of a Holder Election under this Section 8,
the Corporation shall promptly provide a copy of such Holder Election to the 
holders of the Series B Preferred and Series C Preferred.

                                  ARTICLE VI

     The preferences and relative, optional and other special rights of the 
shares of Series B Preferred, and the qualifications, limitations or 
restrictions thereof, are as follows:

     1.   DESIGNATION OF SERIES: RANK. The number of shares of Series B
          ---------------------------
Preferred may be increased or decreased, at any time and from time to time, by
resolution of the Board of Directors; provided that no decrease shall reduce the
number of shares of Series B Preferred to a number less than that of the shares
of such series then outstanding. The Series B Preferred shall rank senior to the
Common Stock and the Series A Preferred with respect to the payment of dividends
and as to the distribution of assets upon liquidation, dissolution or winding
up. The Series B Preferred shall rank senior to the Series C Preferred as to the
payment of dividends and junior to the Series C Preferred as to (i) the
distribution of assets upon liquidation, dissolution or winding up, and (ii) the
distribution of assets upon the redemption of the Series B Preferred and Series
C Preferred. Subject to the protective provisions set forth in Section 7(b)
hereof, the Board of Directors may by resolution issue and designate additional
series or classes of Preferred Stock which may rank senior to, junior to, or on
parity with the Series B Preferred with respect to the payment of dividends, the
distribution of assets upon liquidation, dissolution or winding up, redemption
rights, and the other rights, preferences and privileges of such preferred
stock.

     2.   DIVIDENDS AND DISTRIBUTIONS.
          ---------------------------

          (A)  Subject to the prior and superior rights of the holders of any 
shares of any series of Preferred Stock ranking senior to the shares of Series B
Preferred with respect to dividends, the holders of shares of Series B
Preferred, in preference to the holders of Common Stock, Series A Preferred,
Series C Preferred and any other series of Preferred Stock now existing or
hereafter designated which expressly provides by its terms that it is junior to
the Series B Preferred in dividend rights, shall be entitled to receive, when
and as declared by the Board of Directors out of funds legally available
therefor, semiannual dividends payable as hereinafter provided.

Dividends shall begin to accrue with respect to any share of Series B Preferred 
commencing on the date that such share is first issued (the "Original Issue 
Date") and shall accumulate (whether or not earned or declared) and be payable 
on September 30 and March 31 of each year, beginning on March 31, 1995, or, if  
any such day is not a business day of the Corporation, on the next succeeding 
business day (each such payment date being referred to herein as a "Dividend 
Payment date"), at an annual rate of $0.46125 per share of Series B Preferred 
Stock until December 31, 1997 and, thereafter, at an annual rate of $0.39975 per
share of Series B preferred Stock, in each case, calculated on the basis of a 
year of three hundred sixty-five (365)

                                     -11-



 
days. The amount of dividends payable per share for each full semi-annual
dividend period shall be computed by dividing by two the applicable annual rate
of $0.46125 or $0.39975 (rounding the amount payable to any holder of Series B
Preferred, after aggregating amounts payable on all shares of Series B Preferred
held by such holder, to the nearest cent). If less than six (6) months shall
have elapsed from the Original Issue Date of any share or shares of Series B
Preferred to the first Dividend Payment Date after such issuance, the dividends
payable on such Dividend Payment Date shall be the amount payable on each
subsequent Dividend Payment Date multiplied by a fraction, the numerator of
which is the number of days from the Original Issue Date of such share or shares
of the Series B Preferred Stock to such first Dividend Payment Date and the
denominator of which is 182.5. Any dividend (whether or not earned or declared)
not paid in full within fifteen (15) days following the relevant Dividend
Payment Date shall bear interest at the rate of 7.5% per annum with respect to
dividends payable on or prior to December 31, 1997, and 6.5% per annum with
respect to dividends payable after December 31, 1997, calculated as provided
above, commencing at the close of business on such Dividend Payment Date and
continuing until such dividend is paid in full. Any such unpaid interest shall
be payable upon payment of the delinquent dividend or thirty (30) days following
any written demand from the holder for payment thereof. Dividends paid on shares
of Series B Preferred Stock in an amount less than the total amount of such
dividends at the time accumulated and payable on the Series B Preferred shall be
allocated pro rata on a share-by-share basis among all shares of Series B
Preferred at the time outstanding. The Board of Directors may fix a record date
for the determination of holders of shares of Series B Preferred entitled to
receive payment of a dividend or distribution declared thereon, which record
date shall be no more than sixty (60) nor less than ten (10) calendar days prior
to the respective Dividend Payment Date.

          (b)  Any dividend on shares of Series B Preferred shall be payable in
cash or a combination of cash and shares of Series B Preferred, such form of
payment to be determined at the Corporation's election and in its sole
discretion, provided that not less than 13.33% of the dividend payable in any
period on or prior to December 31, 1997 shall be payable in cash. The number of
shares of Series B Preferred so to be issued, if any, shall be computed by
dividing the dollar amount of the dividend to be paid in shares of Series B
Preferred (as determined above) by the amount of six dollars and fifteen cents
($6.15) per share. Any dividends on the Series B Preferred paid in Series B
Preferred shall be paid to any holder only in whole shares of Series B
Preferred, and any fraction shall be paid in cash. The respective portions of
any dividend payable in each of cash and shares of Series B Preferred shall be
distributed pro rata among all holders of Series B Preferred based on each
Holder's respective ownership of Series B Preferred.

          (c)  If a dividend (whether or not earned or declared) or any
redemption or repurchase payment upon any shares of Series B Preferred (or any
interest thereon), or any other outstanding Preferred Stock of the Corporation
ranking on a parity with the Series B Preferred as to dividends, is in arrears,
then no dividend or other distribution may be declared and no redemption or
repurchase payment may be made (and no interest thereon may be paid) on any such
shares (other than dividends or payments made in stock of the Corporation
ranking junior to the Series B Preferred as to dividends, upon liquidation,
dissolution and winding up and
                                     -12-



 
redemption ("Junior Stock")) unless amounts are paid or distributed in respect
of all such arrearages pro rata, so that (i) the amounts so paid or distributed
per share of each such series bear to each other the same ratio that the amounts
in arrears per share of each such series (i.e., the Series B Preferred and any
other outstanding series of Preferred Stock of the Corporation ranking in parity
with the Series B Preferred) bear to each other and (ii) the percentage of each
such amount in arrears which is paid in cash per share of Series B Preferred is
no lower than the percentage of the amount in arrears which is paid or
distributed in cash per share of any such other series. So long as any shares of
Series B Preferred remain outstanding, no dividend shall be paid or declared and
no distribution made on any stock of the Corporation ranking junior to the
Series B Preferred as to dividends or upon liquidation, dissolution or winding
up (other than a dividend payable in Junior Stock), and no shares of stock of
the Corporation ranking junior to the Series B Preferred as to dividends or upon
liquidation, dissolution or winding up or upon redemption or repurchase shall be
purchased, redeemed or otherwise acquired for consideration by the Corporation,
directly or indirectly (other than as a result of a reclassification of Junior
Stock, or the exchange or conversion of one Junior Stock for or into another
Junior Stock, or other than through the use of the proceeds of a substantially
contemporaneous sale of other Junior Stock), unless in each case (i) all
dividends (whether or not earned or declared) on the Series B Preferred then
accrued and in arrears for all past dividend periods (and any interest thereon)
are first paid in full and the full dividend thereon for the then-current
dividend period is paid or declared and set apart for payment and (ii) the
Corporation first pays in full all amounts then due and payable in connection
with any matured redemption obligation on the Series B Preferred or, with
respect to amounts to be paid in cash, sets aside such payable amounts separate
and apart from its other funds, in trust for the pro rata benefit of the holders
of the shares subject to such redemption so as to continue to be available
therefor. Subject to the foregoing, and not otherwise, such dividends (payable
in cash, stock or otherwise) as may be determined by the Board of Directors may
be declared and paid on any Junior Stock, or shares of Junior Stock may be
purchased, redeemed or otherwise acquired for consideration by the Corporation,
from time to time out of any funds legally available therefor, and the Series B
Preferred shall not be entitled to participate in any such dividend, purchase,
redemption or other acquisition, whether payable in cash, stock or otherwise.

          (d)  Notwithstanding Section 2(c) hereof, the Corporation may at any
time, out of funds legally available therefor, (x) repurchase shares of Common
Stock of the Corporation (i) issued to or held by employees, directors or
consultants of the Corporation or its subsidiaries upon termination of their
employment of services, pursuant to an agreement providing for such right of
repurchase, or (ii) issued to or held by any person subject to the Corporation's
right of first refusal to purchase such shares where the purchase is pursuant to
the exercise of such right of first refusal, (y) repurchase the Series C
Preferred in accordance with Section 3.2(b) of the Series C Convertible
Preferred Stock Purchase Agreement dated as of July 17, 1997, and (z) redeem the
Series C Preferred in accordance with Section 8 of Article VIII of this
Certificate of Incorporation, in any case whether or not dividends on the Series
B Preferred shall have been declared and paid or funds set aside therefor.

                                     -13-


 

     3.   VOTING RIGHTS. The holders of Series B Preferred shall have no right 
          -------------
by virtue of their ownership of such shares to vote in the election of directors
of the Corporation and shall have no other voting rights except as expressly 
required by law. Any vote expressly required by law may be given in person or by
proxy, either in writing without a meeting or by vote at any meeting called for 
the purpose.

     4.   REDEMPTION RIGHTS. 
          -----------------

          (a)  Optional Redemption. Subject to the prior written consent of the 
               -------------------
holders of a majority of the shares of Series C Preferred then issued and 
outstanding, the Corporation may, at its sole option and election, redeem (an 
"OPTIONAL REDEMPTION") the Series B Preferred, in whole or in part, at any time 
and from time to time, at a redemption price per share (the "REDEMPTION PRICE") 
of six dollars and fifteen cents ($6.15) plus an amount equal to all dividends 
(whether or not earned or declared ) accrued and unpaid thereon to the 
redemption date. The Redemption Price payable upon any Optional Redemption may 
be paid in cash, the issue of convertible debentures on the terms provided 
herein ("Convertible Debt") or any combination of cash and Convertible Debt, at 
the election of the Corporation in its sole discretion, pursuant to Section 4(e)
hereof, provided that any such amounts payable in cash shall be paid only to the
extent of funds legally available therefor.

          (b)  Holder Redemption. Subject to the prior and superior rights of 
               -----------------
the holders of the shares of Series C Preferred, upon written notice at least
one hundred twenty (120) days prior to December 31 of any calendar year from,
and including the year 2002, by the holders of at least two-thirds (2/3) of the
then outstanding shares of Series B Preferred (a "Holder Election"), the
Corporation shall be required to redeem, to the extent that such shares have not
already been redeemed pursuant to paragraph (a) above, all of the issued,
outstanding and nonredeemed shares of Series B Preferred held by each holder of
Series B Preferred (a "Holder Redemption"), at a price per share equal to the
Redemption Price. In the event of any such Holder Election, the Corporation
shall, out of and only to the extent of funds legally available therefor, redeem
(i) on the December 31 following such Holder Election, one-third of the number
of shares of Series B Preferred then issued and outstanding; (ii) on the second
December 31 following such Holder Election, one-half of the number of shares of
Series B Preferred then issued and outstanding; and (iii) on the third December
31 following such Holder Election, all of the shares of Series B Preferred then
issued and outstanding. The Redemption Price payable upon any Holder Redemption
shall be paid in cash, to the extent of funds legally available therefor.

          (c)  Redemption to be Effected Pro Rata. If, in the case of an 
               ----------------------------------
Optional Redemption pursuant to Section 4(a) hereof, less than all of the Series
B Preferred at the time outstanding is to be redeemed, then the shares so to be
redeemed shall be redeemed pro rata among the holders of the Series B Preferred
based on the total number of shares of Series B Preferred then held.

                                     -14-



 

          (d)  In the event that the Corporation does not have legally available
funds sufficient to pay in full the Redemption Price with respect to each share 
of Series B Preferred being redeemed pursuant to this Section 4 ("REDEEMED 
SHARES"), the Corporation shall redeem the shares of Series B Preferred 
otherwise scheduled for redemption pro rata among the holders of Series B 
Preferred then outstanding , based on the number of shares then held by each 
holder of Series B Preferred.

          (e)  Payment of Redemption Price. In the case of any Optional 
               ---------------------------
Redemption pursuant to Section 4(a), the Corporation may pay the Redemption 
Price in cash, Convertible Debt, or any combination thereof, at the election of 
the Corporation in its sole discretion. In the case of any Holder Redemption 
pursuant to section 4(b), the Corporation shall pay the Redemption Price in 
cash. If the Corporation elects to pay any part of the Redemption Price of an 
Optional Redemption in some combination of cash and Convertible Debt, the 
respective portions of such Redemption Price payable in each such form of 
consideration shall be distributed pro ram among all holders of Series B 
Preferred being redeemed based on each such Holder's respective ownership of the
Series B Preferred being redeemed. The aggregate face value of Convertible Debt 
issuable upon such redemption shall be equal to the aggregate dollar amount of 
the Redemption Price payable in Convertible Debt. Convertible Debt shall bear 
interest at a rate of 7.5% per annum until December 31, 1997 and, thereafter, at
a rate of 6.5% per annum, shall be subordinate in right of payment to all debt 
to financial institutions for money borrowed, shall be payable upon demand at 
any time after September 30, 2002, and shall be evidenced by subordinated 
debentures in substantially the form attached as Exhibit A to this Restated 
Certificate of Incorporation (with such changes thereto as may be agreed by the 
Company and holders of a majority of the shares of Series B Preferred then 
outstanding).
                          
          (f)  Mechanics of Redemption.
               -----------------------

               (i)   Notice of any Optional Redemption of the Series B Preferred
shall be mailed at least thirty (30), but not more than sixty (60), calendar 
days prior to the date fixed for redemption (the "Optional Redemption Date"), to
each holder of Series B Preferred to be redeemed at such holder's address as it 
appears on the books of the Corporation. To facilitate the redemption of the 
Series B Preferred, the Board of Directors may fix a record date for the 
determination of holders of shares of Series B Preferred to be redeemed, which 
date shall not be more than sixty (60) nor less than ten (10) calendar days 
prior to the Optional Redemption Date. 

               (ii)  Notice of any Holder Redemption of the Series B Preferred 
shall be mailed at least thirty (30), but not more than sixty (60), calendar 
days prior to each December 31 redemption date (each, a "Holder Redemption 
Date"), to each holder of Series B Preferred to be redeemed at such holder's 
address as it appears on the books of the Corporation. To facilitate the 
redemption of the Series B Preferred, the Board of Directors may fix a record 
date for the determination of the holders of shares of Series B preferred to be 
redeemed on each Holder Redemption Date, which date shall be not more than sixty
(60), nor less than ten (10) calendar days prior to the respective Holder 
Redemption Date.

                                     -15-



 
               (iii) The holder of any shares of Series B Preferred redeemed 
pursuant to this Section 4 shall not be entitled to receive payment of the 
Redemption Price for such shares until such holder shall cause to be delivered 
to the place specified in the Corporation's notice of redemption (i) the 
certificates representing the shares of Series B Preferred to be redeemed and 
(ii) appropriate endorsements and transfer documents sufficient to transfer such
shares of Series B Preferred to the Corporation free of any adverse interest. In
the event the redemption amount payable on any redeemed share of Series B 
Preferred is not paid in full within fifteen (15) business days after the 
Optional Redemption Date or Holder Redemption Date (as applicable) as provided 
herein, then the unpaid portion of the Redemption Price of such share shall bear
interest at a rate of 12% per annum, commencing at the close of business on the 
Optional Redemption Date or Holder Redemption Date (as applicable) and 
continuing until the redemption price on such share is paid in full. Interest 
shall be computed on the basis of a three hundred sixty-five (365) day year and 
shall be payable on demand.

               (iv)  In the event of any redemption, then upon the Optional 
Redemption Date or Holder Redemption Date and if all funds necessary for such 
redemption shall have been paid (either in cash, Convertible Debt (as 
applicable), or some combination thereof (as applicable)) or set aside by the 
Corporation separate and apart from its other funds in trust for the pro rata 
benefit of the holders of the shares called for redemption, so as to be and 
continue to be available therefor, then the shares so called for redemption 
shall no longer be deemed outstanding, the rights to receive dividends thereon 
shall cease to accrue from and after the applicable Optional Redemption Date or
Holder Redemption Date, and all rights of the holders of the shares of Series B 
Preferred called for redemption shall cease and terminate, excepting only the 
right to receive the Redemption Price therefor (including any accrued and unpaid
dividends, whether or not earned or declared, to the Optional Redemption Date or
Holder Redemption Date (as the case may be)) if such price has not already been 
paid, without interest except as provided in Section 4(f)(iii) hereof.

          (g)  Priority on Redemption. The redemption rights of the shares of 
               ----------------------
Series B Preferred are subject to the prior and superior rights of the holders 
of any shares of Series C Preferred. Accordingly, if on any applicable Holder 
Redemption Date, any shares of Series C Preferred remain outstanding, the 
holders of the Series C Preferred shall be entitled to have all of their shares 
redeemed prior to the redemption of any shares of Series B Preferred. Upon its 
receipt of a Holder Election under this Section 4, the Corporation shall 
promptly provide a copy of such Holder Election to the holders of the Series C 
Preferred.

     5.   LIQUIDATION. Subject to the prior and superior rights of the holders
          -----------
of any shares of Series C Preferred and of shares of any other series of
Preferred Stock now existing or hereafter designated ranking senior to the
shares of Series B Preferred with respect to liquidation preference, in the
event of any voluntary or involuntary dissolution, liquidation or winding up of
the Corporation (for the purposes of this Section 5, a "LIQUIDATION"), before
any distribution of assets shall be made to the holders of the Common Stock,
Series A Preferred Stock or any other series of Preferred Stock now existing or
hereafter designated that by its express terms ranks

                                     -16-


 
junior to the Series B Preferred in respect of distributions upon the 
Liquidation of the Corporation, the holder of each share of Series B Preferred 
then outstanding shall be entitled to be paid out of the assets of the 
Corporation available for distribution to its stockholders an amount in cash 
equal to $6.15 per share plus all dividends (whether or not earned or 
declared) accrued and unpaid on such share to the date fixed for the 
distribution of assets of the Corporation in liquidation to the holders of 
Series B Preferred.

     If upon any Liquidation the aggregate assets available for distribution to 
the holders of the Series B Preferred and any other stock of the Corporation now
existing or hereafter designated ranking on parity with the Series B Preferred 
upon Liquidation and which shall then be outstanding (hereinafter in this 
paragraph called the "TOTAL AMOUNT AVAILABLE") shall be insufficient to pay to 
the holders of all outstanding shares of Series B Preferred and all such other 
parity stock the full amounts (including all dividends accrued and unpaid) to 
which they shall be entitled by reason of such Liquidation of the Corporation, 
then there shall be paid to the holder of each share of Series B Preferred in 
connection with such Liquidation an amount equal to the product derived by 
multiplying the Total Amount Available times a fraction, the numerator of which 
shall be the full amount to which such share of Series B Preferred shall be 
entitled under the terms of the preceding paragraph by reason of such 
Liquidation and the denominator of which shall be the total amount wich would 
have been distributed by reason of such Liquidation with respect to all Series B
Preferred and other stock ranking on a parity with the Series B Preferred then 
outstanding upon a Liquidation had the Corporation possessed sufficient assets 
to pay the maximum amount which the holders of all such stock would be entitled 
to receive in connection with such Liquidation.

     The voluntary sale, conveyance, lease, exchange or transfer of all or 
substantially all the property or assets of the Corporation, or the merger or 
consolidation of the Corporation into or with any other corporation, or the 
merger of any other corporation into the Corporation (other than any such sale, 
conveyance, lease, exchange or transfer of all or substantially all the property
or assets of the Corporation, merger or consolidation, following which the 
stockholders of the Corporation prior to the transaction retain a majority of 
the voting securities of the surviving or successor corporation and the holders 
of Series B Preferred receive in the transaction a security of the surviving or
successor corporation having rights, preferences, and privileges substantially 
similar to the rights, preferences and privileges of the Series B Preferred), 
shall, at the option of the holders of a majority of the outstanding shares of 
Series B Preferred, be deemed to be a Liquidation of the Corporation for the 
purposes of this Section 5.

     The holder of any shares of Series B Preferred shall not be entitled to 
receive any payment owed for such shares under this Section 5 until such holder 
shall cause to be delivered to the Corporation (i) the certificate(s) 
representing such shares and (i) transfer instrument(s) satisfactory to the 
Corporation and sufficient to surrender such shares to the Corporation free of 
any adverse interest.

                                     -17-

 
     After payment of the full amount of the liquidating distribution to which
any holder of Series B Preferred is entitled, the holder of such share or shares
will not be entitled to any further participation in any distribution of assets
by the Corporation.

     6.   CONVERSION RIGHTS.  The Series B Preferred shall have no conversion 
          -----------------
rights.

     7.   PROTECTIVE PROVISIONS.  So long as any shares of Series B Preferred 
          ---------------------
are outstanding, this Corporation shall not, without first obtaining the 
approval (by vote or written consent, as provided by law) of the holders of at 
least a majority of the then outstanding shares of Series B Preferred voting 
together as a class:

          (a)  amend or repeal any provision of, or add any provision to this 
Corporation's Restated Certificate of Incorporation if such action would 
adversely alter or change the preferences, rights, privileges or powers of, or 
the restrictions provided for the benefit of, the Series B Preferred;

          (b)  authorize or issue shares of any class of stock (other than the
Series B Preferred issued as dividends as described in this Article VI) having
any preference or priority as to dividend, redemption or liquidation preferences
which is superior or equal to any such preferences or priority of shares of
Series B Preferred; or

          (c)  repurchase any outstanding shares of Series A Preferred or Common
Stock, except pursuant to any repurchase agreements between the Company and any
employee, consultant or director which provide for the repurchase by the Company
of shares held by such person upon termination of services to the Corporation.

     8.   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
that a cash dividend) other distribution, any right to subscribe for, purchase
or otherwise acquire any shares of stock of any class or any other securities or
property, or to receive any other right, the Corporation shall mail to each
holder of Series B Preferred, at least fifteen (15) days prior to the date
specified therein, a notice specifying the date on which any such record is to
be taken for the purpose of such dividend, distribution or right, and the amount
and character of such dividend, distribution or right.

                                  ARTICLE VII

          The preferences and relative, optional and other special rights of the
shares of Series C Preferred, and the qualifications, limitations or 
restrictions thereof, are as follows:

     1.   DESIGNATION OF SERIES: RANK.  The number of shares of Series C 
          --------------------------- 
Preferred may be increased or decreased, at any time and from time to time, by 
resolution of the Board of Directors; provided that no decrease shall reduce the
number of shares of Series C Preferred to

                                     -18-

 
a number less than that of the shares of such series then outstanding. The
Series C Preferred shall rank senior to the Common Stock of the Corporation, the
Series A Preferred and Series B Preferred as to the distribution of assets upon
liquidation, dissolution or winding up and upon redemption and shall rank senior
to the Common Stock of the Corporation and the Series A Preferred with respect
to the payment of dividends. The Series C Preferred shall rank junior to the
Series B Preferred with respect to the payment of dividends. Subject to the
protective provisions set forth in Section 7(b) hereof, the Board of Directors
may by resolution issue and designate additional series or classes of Preferred
Stock which may rank senior to, junior to, or on parity with the Series C
Preferred with respect to the payment of dividends, the distribution of assets
upon liquidation, dissolution or winding up, redemption rights, and the other
rights, preferences and privileges of such preferred stock.

     2.   DIVIDENDS AND DISTRIBUTIONS.
          ---------------------------

          (a) Subject to the prior and superior rights of the holders of Series
B Preferred and any shares of any other series of Preferred Stock ranking senior
to the shares of Series C Preferred with respect to dividends, the holders of
shares of Series C Preferred, in preference to the holders of Common Stock, the
Series A Preferred and any series of Preferred Stock now existing or hereafter
designated which expressly provides by its terms that it is junior to the Series
C Preferred in dividend rights, shall be entitled to receive, when and as
declared by the Board of Directors out of funds legally available therefor, an
annual cash dividend in the amount of $0.26325 per share. Such dividends shall
not be cumulative, and no right shall accrue to holders of Series C Preferred by
reason of the fact that dividends on such shares are not declared or paid in any
year.

          (b) If a dividend (whether or not earned or declared) or any
redemption or repurchase payment upon any shares of Series C Preferred (or any
interest thereon), or any other outstanding Preferred Stock of the Corporation
ranking on a parity with the Series C Preferred as to dividends, is in arrears,
then no dividend or other distribution may be declared and no redemption or
repurchase payment may be made (and no interest thereon may be paid) on any such
shares (other than dividends or payments made in stock of the Corporation
ranking junior to the Series C Preferred as to dividends, upon liquidation,
dissolution and winding up and redemption ("Junior Stock")) unless amounts are
paid or distributed in respect of all such arrearages pro rata, so that (i) the
amounts so paid or distributed per share of each such series bear to each other
the same ratio that the amounts in arrears per share of each such series (i.e.,
the Series C Preferred and any other outstanding series of Preferred Stock of
the Corporation ranking in parity with the Series C Preferred) bear to each
other and (ii) the percentage of each such amount in arrears which is paid in
cash per share of Series C Preferred is no lower than the percentage of the
amount in arrears which is paid or distributed in cash per share of any such
other series. So long as any shares of Series C Preferred remain outstanding, no
dividend shall be paid or declared and no distribution made on any stock of the
Corporation ranking junior to the Series C Preferred as to dividends or upon
liquidation, dissolution or winding up (other than a dividend payable in Junior
Stock), and no shares of stock of the Corporation ranking junior to
                                     -19-

 
the Series C Preferred as to dividends or upon liquidation, dissolution or
winding up or upon redemption or repurchase shall be purchased, redeemed or
otherwise acquired for consideration by the Corporation, directly or indirectly
(other than as a result of a reclassification of Junior Stock, or the exchange
or conversion of one Junior Stock for or into another Junior Stock, or other
than through the use of the proceeds of a substantially contemporaneous sale of
other Junior Stock), unless in each case (i) all dividends on the Series C
Preferred then declared and in arrears for all past dividend periods (and any
interest thereon) are first paid in full and the full dividend of $0.26325 for
the then-current dividend period is paid or declared and set apart for payment
and (ii) the Corporation first pays in full all amounts then due and payable in
connection with any matured repurchase or redemption obligation on the Series C
Preferred or, with respect to amounts to be paid in cash, sets aside such
payable amounts separate and apart from its other funds, in trust for the pro
rata benefit of the holders of the shares subject to such redemption so as to
continue to be available therefor. Subject to the foregoing, and not otherwise,
such dividends (payable in cash, stock or otherwise) as may be determined by the
Board of Directors may be declared and paid on any Junior Stock, or shares of
Junior Stock may be purchased, redeemed or otherwise acquired for consideration
by the Corporation, from time to time out of any funds legally available
therefor, and the Series C Preferred shall not be entitled to participate in any
such dividend, purchase, redemption or other acquisition, whether payable in
cash, stock or otherwise.

          (c)  Notwithstanding Section 2(b) hereof, the Corporation may at any
time, out of funds legally available therefor, repurchase shares of Common Stock
of the Corporation (i) issued to or held by employees, directors or consultants
of the Corporation or its subsidiaries upon termination of their employment of
services, pursuant to an agreement providing for such right of repurchase,
or (ii) issued to or held by any person subject to the Corporation's right of
first refusal to purchase such shares where the purchase is pursuant to the
exercise of such right of first refusal, in either case whether or not dividends
on the Series C Preferred shall have been declared and paid or funds set aside
therefor.

     3.    VOTING RIGHTS. Except as otherwise required by law, each share of
           -------------
Series C Preferred issued and outstanding shall at any time have a number of
votes equal to the number of shares of Common Stock into which such share of
Series C Preferred is then convertible pursuant to Section 5 hereof. Subject to
the foregoing, the holders of Series C preferred shall be entitled to vote with
the holders of Common Stock on all matters submitted to a vote of stockholders
(whether at a meeting or by written consent); provided that, subject to section
1 hereof, the Series C Preferred shall be entitled to vote as a separate series
(the affirmative vote or consent of the holders of at least a majority of the
outstanding shares of such separate series being required) or as part of a class
(together with other series of Preferred Stock) on any matter with respect to
which a series vote by the Series C Preferred or a class vote of the Preferred
Stock, as the case may be, shall be expressly required by law, and any such
class or series vote may be given in person or by proxy, either in writing
without a meeting or by vote at any meeting called for the purpose.

                                     -20-

 
     4.   LIQUIDATION.  Subject to the prior and superior rights of the holders 
          -----------
of any shares of any series of Preferred Stock ranking senior to the shares of 
Series C Preferred with respect to liquidation preference, in the event of any 
voluntary or involuntary dissolution, liquidation or winding up of the 
Corporation (for the purposes of this Section 4, a "LIQUIDATION"), before any 
distribution of assets shall be made to the holders of the Common Stock, Series 
A Preferred, Series B Preferred or the holders of any stock now existing or 
hereafter designated that by its express terms ranks junior to the Series C 
Preferred in respect of distributions upon the Liquidation of the Corporation, 
the holder of each share of Series C Preferred then outstanding shall be 
entitled to be paid out of the assets of the Corporation available for 
distribution to its stockholders an amount in cash equal to $3.51 per share plus
all dividends declared and unpaid on such share on the date fixed for the 
distribution of assets of the Corporation in liquidation to the holders of 
Series C Preferred.

     If upon any Liquidation the aggregate assets available for distribution to 
the holders of the Series C Preferred and any other stock of the Corporation now
existing or hereafter designated ranking on parity with the Series C Preferred 
upon Liquidation and which shall then be outstanding (hereinafter in this 
paragraph called the "TOTAL AMOUNT AVAILABLE") shall be insufficient to pay to 
the holders of all outstanding shares of Series C Preferred and all such other 
parity stock the full amounts (including all dividends accrued and unpaid) to 
which they shall be entitled by reason of such Liquidation of the Corporation, 
then there shall be paid to the holder of each share of Series C Preferred in 
connection with such Liquidation an amount equal to the product derived by 
multiplying the Total Amount Available times a fraction, the numerator of which 
shall be the full amount to which such share of Series C Preferred shall be
entitled under the terms of the preceding paragraph by reason of such 
Liquidation and the denominator of which shall be the total amount which would  
have been distributed by reason of such Liquidation with respect to all Series C
Preferred and other stock ranking on a parity with the Series C Preferred then 
outstanding upon a Liquidation had the Corporation possessed sufficient assets 
to pay the maximum amount which the holders of all such stock would be entitled 
to receive in connection with such Liquidation.

     The voluntary sale, conveyance, lease, exchange or transfer of all or 
substantially all the property or assets of the Corporation, or the merger or 
consolidation of the Corporation into or with any other corporation, or the 
merger of any other corporation into the Corporation (other than any such sale, 
conveyance, lease, exchange or transfer of all or substantially all the property
or assets of the Corporation, merger or consolidation, following which the 
stockholders of the Corporation prior to the transaction retain a majority of 
the voting securities of the surviving or successor corporation and the holders 
of Series C Preferred receive in the transaction a security of the surviving or 
successor corporation having rights, preferences, and privileges substantially 
similar to the rights, preferences and privileges of the Series C Preferred), or
the transfer of the voting control of the Corporation shall, at the option of 
the holders of a majority of the outstanding shares of Series C Preferred, be 
deemed to be a Liquidation of the Corporation for the purposes of this Section 
4.

                                     -21-

 
     The holder of any shares of Series C Preferred shall not be entitled to 
receive any payment owed for such shares under this Section 4 until such holder
shall cause to be delivered to the Corporation (i) the certificate(s)
representing such shares and (ii) transfer instrument(s) satisfactory to the
Corporation and sufficient to surrender such shares to the Corporation free of
any adverse interest.

     After payment of the full amount of the liquidating distribution to which 
any holder of Series C Preferred is entitled, the holder of such share or shares
will not be entitled to any further participation in any distribution of assets 
by the Corporation.

     5.   CONVERSION RIGHTS.
          -----------------

          (a)  Optional Conversion into Common Stock. The holder of any share of
               -------------------------------------
Series C Preferred shall have the right, at such holder's option, at any time to
convert such share into that number of shares of fully paid and nonassessable 
whole shares of Common obtained by dividing $3.51 by the Series C Conversion 
Price then in effect. The Series C Conversion Price shall initially be $3.51 per
share, and shall be subject to adjustment as set forth below.

          (b)  Automatic Conversion.  Each share of Series C Preferred shall 
               --------------------
automatically convert into shares of fully paid and nonassessable Common Stock, 
without any further action required on the part of the holder thereof, 
immediately prior to the closing of the Corporation's initial underwritten 
public offering pursuant to a Registration Statement filed with and declared 
effective by the Securities and Exchange Commission under the Securities Act of 
1933, as amended, covering the offer and sale of Common Stock for the account of
the Corporation in which the aggregate proceeds to the Corporation equal at 
least $15,000,000 and in which the price per share of Common Stock equals or 
exceeds $7.02 per share (as adjusted for stock splits, stock dividends, 
recapitalizations and similar events) (the "Qualified Public Offering"). The 
number of shares of Common Stock issuable upon such automatic conversion of any 
such share shall be equal to the number obtained by dividing $3.51 by the Series
C Conversion Price then in effect.

          (c)  Procedure for Conversion. To exercise the conversion privilege 
               ------------------------
set forth in Section 5(a) hereof, the holder of shares of Series C Preferred  
shall surrender the shares to be converted, accompanied by instruments of 
transfer satisfactory to the Corporation and sufficient to transfer the shares 
being converted to the Corporation free of any adverse interest, at the 
principal offices of the Corporation or any of the offices or agencies 
maintained for such purpose by the Corporation ("Conversion Agent") and shall 
give written notice (by registered or certified mail, overnight courier or hand 
delivery) to the Corporation at such Conversion Agent that the holder elects to 
convert such shares. Such notice shall state whether and to what extent the 
shares so surrendered for conversion shall be converted into shares of Common 
Stock, and shall also state the name or names, together with address or 
addresses, in which the certificate or certificates for Common Stock issuable on
such conversion shall be issued. As promptly as practicable after the surrender 
of such shares of Series C Preferred as aforesaid, the Corporation shall issue 
and deliver at such Conversion Agent to such holder, or on such holder's written
order, a certificate

                                     -22-

 
or certificates for the number of full shares of Common Stock issuable upon the
conversion of such shares in accordance with the provisions hereof. Certificates
will be issued for the balance of the shares of Series C Preferred in any case
in which fewer than all of the shares of Series C Preferred are converted.

          Each conversion pursuant to Section 5(a) hereof shall be deemed to
have been effected immediately prior to the close of business on the date on
which the shares of Series C Preferred shall have been so surrendered and such
notice shall have been received by the Corporation as aforesaid. Each conversion
pursuant to Section 5(b) hereof shall be deemed to have been effected,
automatically and with no further required action on the part of the holder of
the shares as converted, immediately prior to (but contingent upon) the closing
of the sale of shares pursuant to the Qualified Public Offering. In each such
case, the person or persons in whose name or names any certificate or
certificates for shares of Common Stock shall be issuable upon such conversion
shall be deemed to have become the holder or holders of record of the Common
Stock represented thereby at the effective date of such conversion, unless the
stock transfer books of the Corporation shall be closed on such date, in which
event such conversion shall be deemed to have been effected immediately prior to
the open of business on the next succeeding day on which such stock transfer
books are open, and such person or persons shall be deemed to have become such
holder or holders of record of the Common Stock at the open of business on such
later day. In each such case, the conversion shall be at the Conversion Price in
effect on the effective date of the conversion as determined above. No payment
or adjustment shall be made on conversion for any dividends payable on the
Common Stock delivered on conversion. Effective as of any such conversion, the
Corporation shall be excused from paying any dividends on the shares converted,
except for any dividends accrued (whether or not earned or declared) and unpaid
through the day of conversion.

     No fractional interest in a share of Common Stock shall be deliverable upon
the conversion of any share or shares of Series C Preferred, and the number of 
shares of Common Stock issuable upon any such conversion shall be rounded down 
to the nearest whole share. If more than one certificate representing shares of
Series C Preferred is to be converted at one time by the same holder into common
Stock, the number of full shares of Common Stock issuable upon conversion 
thereof shall be computed on the basis of the aggregate number of shares of 
Series C Preferred represented by such certificates, or the specified portions 
thereof to be converted.

          (d)  Adjustment of Conversion Price.  The Conversion Price shall be 
               ------------------------------
adjusted from time to time in respect of any of the following events occurring
on or after the date upon which a share of Series C Preferred is first issued
(the "ORIGINAL ISSUE DATE" of the Series C Preferred), as follows:

               (i)  Dividends and Distributions.  In case the Corporation shall 
                    ---------------------------
pay or make a dividend or other distribution upon its Common Stock payable in 
Common Stock, the Conversion Price in effect at the opening of business on the 
day following the date fixed for the determination of stockholders entitled to 
receive such dividend or other distribution shall be 

                                     -23-

 
reduced by multiplying such Conversion Price by a fraction, of which the 
numerator shall be the number of shares of Common Stock outstanding at the close
of business on the date fixed for such determination and the denominator shall 
be the sum of such number of shares and the total number of shares constituting
such dividend or other distribution, such reduction to become effective 
immediately after the opening of business on the day following the date fixed 
for such determination.  For the purposes of this paragraph (i), the number of 
shares of Common Stock at any time outstanding shall not include shares held in 
the treasury of the Corporation.  The Corporation will not pay any dividend or 
make any distribution on shares of Common Stock held in the treasury of the 
Corporation.

               (ii)   Subdivisions and Combinations.  In case the outstanding 
                      -----------------------------
shares of Common Stock shall each be subdivided into a greater number of shares 
of Common Stock (other than any such subdivision which is effected pursuant to a
dividend or distribution for which adjustment to the Conversion Price is made 
under paragraph (i) above), the Conversion Price in effect at the opening of 
business on the day following the day upon which such subdivision becomes 
effective shall be proportionately reduced and, conversely, in case the 
outstanding shares of Common Stock shall each be combined into a smaller number 
of shares of Common Stock, the Conversion Price in effect at the opening of 
business on the day following the day upon which such combination becomes 
effective shall be proportionately increased, such reduction or increase, as the
case may be, to become effective immediately after the opening of business on 
the day following the day upon which such subdivision or combination becomes 
effective.

               (iii)  Distributions other than Cash Dividends.  In case the 
                      ---------------------------------------
Corporation shall declare a cash dividend upon its Common Stock payable 
otherwise than out of retained earnings or shall distribute to holders of its 
Common Stock shares of its capital stock (other than Common Stock), stock or 
other securities of other persons, evidences of indebtedness issued by the 
Corporation or other persons, assets (excluding cash dividends out of retained 
earnings) or options or rights (excluding options to purchase and rights to 
subscribe for Common Stock or other securities of the Corporation convertible 
into or exchangeable for Common Stock), then, in each such case, the holders of 
shares of Series C Preferred shall, concurrently with the distribution to 
holders of Common Stock, receive a like distribution based upon the number of 
shares of Common Stock into which such shares of Series C Preferred shall then 
be convertible.

               (iv)   Reclassifications.  In case of any capital reorganization
                      -----------------
or reclassification of the stock of the Corporation (other than any transaction
described in paragraph (i), (ii) or (iii) hereof), or the consolidation or
merger of the Corporation with or into another person (other than a
consolidation or merger in which the Corporation is the continuing entity and
which does not result in any change in the Common Stock), the shares of the
Series C Preferred shall, after such reorganization, reclassification,
consolidation or merger, be convertible into the kind and number of shares of
stock or other securities or property of the Corporation or otherwise to which
the holder thereof would have been entitled if immediately prior to such
reorganization, reclassification, consolidation, or merger the holder had
converted the holder's shares of the Series C Preferred in Common Stock.

                                     -24-

 
                    (v) (A) Upon Sale of Common Stock. If the Corporation shall,
                            -------------------------
while there are any shares of Series C Preferred outstanding, issue or sell (or
in accordance with Section 5(d)(v)(B) below is deemed to have issued or sold)
shares of its Common Stock without consideration or at a price per share less
than the Conversion Price in effect immediately prior to such issuance or sale,
then in each such case such Conversion Price for the Series C Preferred, upon
each such issuance or sale, except as hereinafter provided, shall be lowered so
as to be equal to an amount determined by multiplying the Conversion Price by a
fraction:

          (1)  the numerator of which shall be (a) the number of shares of
     Common Stock outstanding immediately prior to the issuance of such
     additional shares of Common Stock, plus (b) the number of shares of Common
     Stock which the net aggregate consideration, if any, received by the
     Corporation for the total number of such additional shares of Common Stock
     so issued would purchase at the Conversion Price in effect immediately
     prior to such issuance, and

          (2)  the denominator of which shall be (a) the number of shares of
     Common Stock outstanding immediately prior to the issuance of such
     additional shares of Common Stock plus (b) the number of such additional
     shares of Common Stock so issued;


provided that for the purpose of clauses (1) and (2) of this Subsection 5 
(d)(v)(A), all shares of Common Stock issuable upon conversion of the 
outstanding shares of Series A Preferred and Series C Preferred and all shares 
of Common Stock issuable upon exercise of outstanding options and warrants shall
be deemed to be outstanding.

               (B) Upon Issuance of Warrants, Options and Rights to Common
                   -------------------------------------------------------
                   Stock.
                   -----

          (1)  For the purposes of this Section 5(d)(v), the issuance of any
     warrants, options, subscriptions, or purchase rights with respect to shares
     of Common Stock and the issuance of any securities convertible into or
     exchangeable for shares of Common Stock (or the issuance of any warrants,
     options or any rights with respect to such convertible or exchangeable
     securities) shall be deemed an issuance of such Common Stock at such time
     if the Net Consideration Per Share (as hereinafter determined) which may be
     received by the Corporation for such Common Stock shall be less than the
     Conversion Price at the time of such issuance. Any obligation, agreement,
     or undertaking to issue warrants, options, subscriptions, or purchase
     rights at any time in the future shall be deemed to be an issuance at the
     time such obligation, agreement or undertaking is made or arises. No
     adjustment of the Conversion Price shall be made under this Section 5(d)(v)
     upon the issuance of any shares of Common Stock which are issued pursuant
     to the exercise of any warrants, options, subscriptions, or purchase rights
     or pursuant to the exercise of any conversion or exchange rights in any
     convertible securities if any adjustment shall previously have been made or
     deemed not required hereunder, upon the issuance of any such warrants,
     options, or subscription or purchase rights or upon the issuance of any
     convertible securities (or upon the issuance of any warrants, options or
     any rights therefor) as above provided.

                                     -25-

 
Should the Net Consideration Per Share of any such warrants, options,
subscriptions, or purchase rights or convertible securities be decreased from
time to time (other than as a result of a stock split, stock dividend or other
similar event), then, upon the effectiveness of each such change, the Conversion
Price shall be adjusted to such Conversion Price as would have obtained (1) had
the adjustments made upon the issuance of such warrants, options, rights, or
convertible securities been made upon the basis of the decreased Net
Consideration per share of such securities, and (2) had adjustments made to the
Conversion Price since the date of issuance of such securities been made to the
Conversion Price as adjusted pursuant to (1) above. Any adjustment of the
Conversion Price with respect to this Section 5(d)(v)(B) which relates to
warrants, options, subscriptions, purchase rights or convertible securities with
respect to shares of Common Stock shall be disregarded if, as, when and to the
extent such warrants, options, subscriptions, purchase rights or convertible
securities expire or are canceled without being exercised or converted, so that
the Conversion Price effective immediately upon such cancellation or expiration
shall be equal to the Conversion Price in effect at the time of the issuance of
the expired or canceled warrants, options, subscriptions, purchase rights, or
convertible securities with such additional adjustments as would have been made
to that Conversion Price had the expired or canceled warrants, options,
subscriptions, purchase rights or convertible securities not been issued.

     (2)  For purposes of this paragraph, the "Net Consideration Per Share"
which may be received by the Corporation shall be determined as follows:

          (a) The "Net Consideration Per Share" shall mean the amount equal to
     the total amount of consideration, if any, received by the Corporation for
     the issuance of all such warrants, options, subscriptions, or other
     purchase rights or convertible or exchangeable securities, plus the minimum
     amount of consideration, if any, payable to the Corporation upon exercise
     or conversion thereof, divided by the aggregate number of shares of Common
     Stock that would be issued if all such warrants, options, subscriptions, or
     other purchase rights or convertible or exchangeable securities were
     exercised, exchanged, or converted.

          (b) The "Net Consideration Per Share" which may be received by the
     Corporation shall be determined in each instance as of the date of issuance
     of warrants, options, subscriptions, or other purchase rights or
     convertible or exchangeable securities without giving effect to any
     possible future upward price adjustments or rate adjustments which may be
     applicable with respect to such warrants, options, subscriptions, or other
     purchase rights or convertible or exchangeable securities.

          (c)  Stock Dividends. In the event the Corporation shall make or 
               ---------------
issue a dividend or other distribution payable in Common Stock or securities of
the Corporation convertible into or otherwise exchangeable for the Common Stock
of the Corporation which

                                    -26-

 
     is not subject to Section 5(d)(i) above, then such Common Stock or other
     securities issued in payment of such dividend shall be deemed to have been
     issued without consideration (except for dividends payable in shares of
     Common Stock payable pro rata to holders of Series C Preferred Stock and to
                          --------
     holders of any other class of stock).

               (D)    Consideration Other than Cash. For purposes of this
                      -----------------------------
     Section 5(d), if a part or all of the consideration received by the
     Corporation in connection with the issuance of shares of the Common Stock
     or the issuance of any of the securities described in this Section 5(d)(v)
     consists of property other than cash, such consideration shall be deemed to
     have a fair market value as is reasonably determined in good faith by the
     Board of Directors of the Corporation.

               (E)    Exceptions. This Section 5(d)(v) shall not apply under any
                      ----------
     of the circumstances which are described in Sections 5(d)(i), (ii) i (iii)
     or (iv) above. Further, the provisions of this Section 5(d)(v) shall not
     apply to (i) shares issued upon conversion of the Series A Preferred or
     Series C Preferred, (ii) options (and the shares issuable upon exercise
     thereof) to purchase up to an aggregate of 1,841,375 shares of Common Stock
     granted or to be granted to employees, directors and consultants of the
     Corporation, (iii) shares issued upon conversion of warrants to purchase an
     aggregate of 144,540 shares of Common Stock outstanding on the Original

discretion make such reductions in the Conversion Price, in addition to those

newly issued and, when issued, shall be duly authorized, validly issued, fully 
paid and nonassessable, and free and clear of any liens or encumbrances.

     6.   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, any right to subscribe for, 
purchase or otherwise acquire any shares of stock of any class or any other 
securities or property, or to receive any other right, the Corporation shall 
mail to each holder of Series C Preferred, at least fifteen (15) days prior to 
the date specified therein, a notice specifying the date on which any such 
record is to be taken for the purpose of such dividend, distribution or right, 
and the amount and character of such dividend, distribution or right.


     7.   PROTECTIVE PROVISIONS. So long as any shares of Series C Preferred are
          ---------------------
outstanding, this Corporation shall not, without first obtaining the approval 
(by vote or written consent, as provided by law), of the holders of at least a 
majority of the then outstanding shares of Series C Preferred voting together as
a class:

          (a)  amend or repeal any provision of, or add any provision to, this 
Corporation's Restated Certificate of Incorporation if such action would 
adversely alter or change the preferences, rights, privileges or powers of, or 
the restrictions provided for the benefit of, the Series C Preferred; or

          (b)  authorize or issue shares of any class of stock (other than the

priority of any series of Series C Preferred.

          (c)  Merge or consolidate with or into another entity or sell, lease 
or otherwise dispose of a material portion of the assets of the Company or any 
subsidiary or transfer voting control of the Company if the total consideration 
to be received by the holders of the Series C Preferred Stock is less than the 
lesser of (i) $7.02 per share of Series C Preferred (as adjusted for stock 
splits, stock dividends, recapitalizations and similar events) and (ii) $4.74 
per share of Series C Preferred (as adjusted for stock splits, stock dividends,
recapitalizations and similar events), with respect to transactions occurring on
or prior to the first anniversary of the Original Issue Date of the Series C 
Preferred and thereafter an amount per share of Series C Preferred which would 
result in the holder of a share of Series C Preferred realizing an annual 
cumulative internal rate of return of 35% on the original purchase price paid 
per share of Series C Preferred, which consent shall not be unreasonably 
withheld;

     8.   REDEMPTION RIGHTS.
          -----------------

          (a)  Holder Redemption. Upon written notice at least one hundred 
               -----------------
twenty (120) days prior to December 31 of any calendar year from, and including,
the year 2002, by the

                                     -28-

 
holders of at least two-thirds (2/3) of the then outstanding shares of Series C
Preferred (a "Holder Election"), the Corporation shall be required to redeem all
of the issued, outstanding and nonredeemed shares of Series C Preferred held by
each holder of Series C Preferred (a "Holder Redemption"), at a redemption price
per share (the "Redemption Price") of $3.51 plus an amount equal to all declared
but unpaid dividends on the Series C Preferred. In the event of any such Holder
Election, the Corporation shall, out of and only to the extent of funds legally
available therefor, redeem (i) on the December 31 following such Holder
Election, one-third of the number of shares of Series C Preferred then issued
and outstanding; (ii) on the second December 31 following such Holder Election,
one-half of the number of shares of Series C Preferred then issued and
outstanding; and (iii) on the third December 31 following such Holder Election,
all of the shares of Series C Preferred then issued and outstanding. The
Redemption Price Payable upon any Holder Redemption shall be paid in cash, to
the extent of funds legally available therefor.

          (b) In the event that the Corporation does not have legally available
funds sufficient to pay in full the Redemption Price with respect to each share
of Series C Preferred being redeemed pursuant to this Section 8 ("REDEEMED
SHARES"), the Corporation shall redeem the shares of Series C Preferred
otherwise scheduled for redemption pro rata among the holders of the Series C
Preferred then outstanding, based on the number of shares then held by each
holder of Series C Preferred.


          (c)  Payment of Redemption Price. In the case of any Holder Redemption
               --------------------------- 
pursuant to Section 4(a), the Corporation shall pay the Redemption Price in 
cash.

          (d)  Mechanics of Redemption.
               -----------------------

               (i) Notice of any Holder Redemption of the Series C Preferred
shall be mailed at least thirty (30), but not more than sixty (60), calendar
days prior to each December 31 redemption date (each, a "Holder Redemption
Date"), to each holder of Series C Preferred to be redeemed at such holder's
address as it appears on the books of the Corporation. To facilitate the
redemption of the Series C Preferred, the Board of Directors may fix a record
date for the determination of the holders of shares of Series C Preferred to be
redeemed on each Holder Redemption Date, which date shall be not more than sixty
(60), nor less than ten (10) calendar days prior to the respective Holder
Redemption Date.

               (ii) The holder of any shares of Series C Preferred redeemed 
pursuant to this Section 8 shall not be entitled to receive payment of the 
Redemption Price for such shares until such holder shall cause to be delivered 
to the place specified in the Corporation's notice of redemption (i) the 
certificates representing the shares of Series C Preferred to be redeemed and 
(ii) appropriate endorsements and transfer documents sufficient to transfer such
shares of Series C Preferred to the Corporation free of any adverse interest. In
the event the redemption amount payable on any redeemed share of Series C 
Preferred is not paid in full within fifteen (15) business days after the Holder
Redemption Date as provided herein, then the unpaid portion of the Redemption 
Price of such share shall bear interest at a rate of 12% per annum, commencing 
at

                                     -29-







 
the close of business on the Holder Redemption Date and continuing until the 
redemption price on such share is paid in full. Interest shall be computed on 
the basis of a three hundred sixty-five (365) day year and shall be payable on 
demand.

               (iii)     In the event of any redemption, then upon the Holder 
Redemption Date and if all funds necessary for such redemption shall have been 
paid in cash or set aside by the Corporation separate and apart from its other 
funds in trust for the pro rata benefit of the holders of the shares called for 
redemption, so as to be and continue to be available therefor, then the shares 
so called for redemption shall no longer be deemed outstanding, the rights to 
receive dividends thereon shall cease to accrue from and after the applicable 
Holder Redemption Date, and all rights of the holders of the shares of Series C
Preferred called for redemption shall cease and terminate, excepting only the 
right to receive the Redemption Price therefor (including any accrued and unpaid
dividends, whether or not earned or declared, to the Holder Redemption Date if 
such price has not already been paid, without interest except as provided in 
Section 4(d)(ii) hereof.

          (e)  Conversion Rights. Nothing contained in this Section 8 shall in 
               -----------------
any way restrict or prohibit the holders of the Series C Preferred from 
exercising their conversion rights pursuant to Section 5 hereof prior to the 
redemption of any shares hereunder.

          (f)  Priority on Redemption. The redemption rights of the shares of 
               ----------------------
Series C Preferred are senior to the redemption rights of the Series A Preferred
and Series B Preferred. Accordingly, the Corporation shall not redeem any shares
of Series A Preferred or Series B preferred unless and until the shares of 
Series C Preferred have been redeemed in full.
