                                      OF

                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK

                        (Pursuant to Section 151 of the
                       Delaware General Corporation Law)

     Evolving Systems, Inc., a corporation organized and existing under the
General Corporation Law of the State of Delaware (hereinafter called the
"Company"), hereby certifies that the following resolution was adopted by the
Board of Directors of the Corporation as required by Section 151 of the General
Corporation Law at a meeting duly called and held on February 23, 1999:

                  Resolved, that pursuant to the authority granted to and 
             vested in the  Board of Directors of the Company in accordance 
             with the provisions of its Amended and Restated Certificate of 
             Incorporation, the Board of Directors hereby creates a series 
             of Preferred Stock, par value $.001 per share, of the Company 
             and hereby states the designation and number of shares, and 
             fixes the relative designations and the powers, preferences 
             and rights, and the qualifications, limitations and restrictions 
             thereof (in addition to the provisions set forth in the 
             Certificate of Incorporation of the Company, which are applicable
             to the Preferred Stock of all classes and series), as follows:

Series A Junior Participating Preferred Stock:

      Section 1.  Designation and Amount.  Two hundred and fifty
thousand (250,000) shares of Preferred Stock, $.001 par value, are designated
"Series A Junior Participating Preferred Stock" with the designations and the
powers, preferences and rights, and the qualifications, limitations and
restrictions specified herein (the "Junior Preferred Stock").  Such number of
shares may be increased or decreased by resolution of the Board of Directors;
provided, that no decrease shall reduce the number of shares of Junior Preferred
Stock to a number less than the number of shares then outstanding plus the
number of shares reserved for issuance upon the exercise of outstanding options,
rights or warrants or upon the conversion of any outstanding securities issued
by the Company convertible into Junior Preferred Stock.

     Section 2.   Dividends and Distributions.

             (A) Subject to the rights of the holders of any shares of any
     series of Preferred Stock (or any similar stock) ranking prior and superior
     to the Junior Preferred Stock with respect to dividends, the holders of
     shares of Junior Preferred Stock, in preference to the holders of 

                                       1

 
     Common Stock, par value $.001 per share (the "Common Stock"), of the
     Company, and of any other junior stock, shall be entitled to receive, when,
     as and if declared by the Board of Directors out of funds legally available
     for the purpose, quarterly dividends payable in cash on the first day of
     April, July, October and January in each year (each such date being
     referred to herein as a "Quarterly Dividend Payment Date"), commencing on
     the first Quarterly Dividend Payment Date after the first issuance of a
     share or fraction of a share of Junior Preferred Stock, in an amount per
     share (rounded to the nearest cent) equal to the greater of (a) $l.00 or
     (b) subject to the provision for adjustment hereinafter set forth, 100
     times the aggregate per share amount of all cash dividends, and 100 times
     the aggregate per share amount (payable in kind) of all non-cash dividends
     or other distributions, other than a dividend payable in shares of Common
     Stock or a subdivision of the outstanding shares of Common Stock (by
     reclassification or otherwise), declared on the Common Stock since the
     immediately preceding Quarterly Dividend Payment Date or, with respect to
     the first Quarterly Dividend Payment Date, since the first issuance of any
     share or fraction of a share of Junior Preferred Stock. In the event the
     Company shall at any time declare or pay any dividend on the Common Stock
     payable in shares of Common Stock, or effect a subdivision or combination
     or consolidation of the outstanding shares of Common Stock (by
     reclassification or otherwise than by payment of a dividend in shares of
     Common Stock) into a greater or lesser number of shares of Common Stock,
     then in each such case the amount to which holders of shares of Junior
     Preferred Stock were entitled immediately prior to such event under clause
     (b) of the preceding sentence shall be adjusted by multiplying such amount
     by a fraction, the numerator of which is the number of shares of Common
     Stock outstanding immediately after such event and the denominator of which
     is the number of shares of Common Stock that were outstanding immediately
     prior to such event.

             (B)  The Company shall declare a dividend or distribution on the
     Junior Preferred Stock as provided in paragraph (A) of this Section
     immediately after it declares a dividend or distribution on the Common
     Stock (other than a dividend payable in shares of Common Stock); provided,
     that in the event no dividend or distribution shall have been declared on
     the Common Stock during the period between any Quarterly Dividend Payment
     Date and the next subsequent Quarterly Dividend Payment Date, a dividend of
     $1.00 per share on the Junior Preferred Stock shall nevertheless be payable
     on such subsequent Quarterly Dividend Payment Date.

             (C) Dividends shall begin to accrue and be cumulative on
     outstanding shares of Junior Preferred Stock from the Quarterly Dividend
     Payment Date next preceding the date of issue of such shares, unless the
     date of issue of such shares is prior to the record date for the first
     Quarterly Dividend Payment Date, in which case dividends on such shares
     shall begin to accrue from the date of issue of such shares, or unless the
     date of issue is a Quarterly Dividend Payment Date or is a date after the
     record date for the determination of holders of shares of Junior Preferred
     Stock entitled to receive a quarterly dividend and before such Quarterly
     Dividend Payment Date, in either of which events such dividends shall begin
     to accrue and be cumulative from such Quarterly Dividend Payment Date.
     Accrued but unpaid dividends shall not bear interest. Dividends paid on the
     shares of Junior Preferred Stock in an amount less than the total amount of
     such dividends at the time accrued and payable on such shares shall be
     allocated pro rata on a share-by-share basis among all such shares at the
     time outstanding. The Board of Directors may fix a record date for the
     determination of holders of shares of Junior Preferred 

                                       2

 
     Stock entitled to receive payment of a dividend or distribution declared
     thereon, which record date shall be not more than 60 days prior to the date
     fixed for the payment thereof.

     Section 3.   Voting Rights. The holders of shares of Junior Preferred Stock
shall have the following voting rights:

             (A)  Subject to the provision for adjustment hereinafter set forth,
     each share of Junior Preferred Stock shall entitle the holder thereof to
     100 votes on all matters submitted to a vote of the stockholders of the
     Company. In the event the Company shall at any time declare or pay any
     dividend on the Common Stock payable in shares of Common Stock, or effect a
     subdivision or combination or consolidation of the outstanding shares of
     Common Stock (by reclassification or otherwise than by payment of a
     dividend in shares of Common Stock) into a greater or lesser number of
     shares of Common Stock, then in each such case the number of votes per
     share to which holders of shares of Junior Preferred Stock were entitled
     immediately prior to such event shall be adjusted by multiplying such
     number by a fraction, the numerator of which is the number of shares of
     Common Stock outstanding immediately after such event and the denominator
     of which is the number of shares of Common Stock that were outstanding
     immediately prior to such event.

             (B)  Except as otherwise provided herein, in any other Certificate
     of Designation creating a series of Preferred Stock or any similar stock,
     or by law, the holders of shares of Junior Preferred Stock and the holders
     of shares of Common Stock and any other capital stock of the Company having
     general voting rights shall vote together as one class on all matters
     submitted to a vote of stockholders of the Company.

             (C)  Except as set forth herein, or as otherwise provided by law,
     holders of Junior Preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

     Section 4.   Certain Restrictions.

             (A)  Whenever quarterly dividends or other dividends or
     distributions payable on the Junior Preferred Stock as provided in Section
     2 are in arrears, thereafter and until all accrued and unpaid dividends and
     distributions, whether or not declared, on shares of Junior Preferred Stock
     outstanding shall have been paid in full, the Company shall not:

                  (i)   declare or pay dividends, or make any other 
     distributions, payable on the Junior Preferred Stock as provided in 
     Section 2 are in arrears, thereafter and until all accured and unpaid 
     windin g up) to the Junior Preferred Stock;

                  (ii)  declare or pay dividends, or make any other
     distributions, on any shares of stock ranking on a parity (either as to
     dividends or upon liquidation, dissolution or winding up) with the Junior
     Preferred Stock, except dividends paid ratably on the Junior Preferred
     Stock and all such parity stock on which dividends are payable or in
     arrears in proportion to the total amounts to which the holders of all such
     shares are then entitled;

                                       3

 
                  (iii) redeem or purchase or otherwise acquire for
     consideration shares of any stock ranking junior (either as to dividends or
     upon liquidation, dissolution or winding up) to the Junior Preferred Stock,
     provided that the Company may at any time redeem, purchase or otherwise
     acquire shares of any such junior stock in exchange for shares of any stock
     of the Company ranking junior (either as to dividends or upon dissolution,
     liquidation or winding up) to the Junior Preferred Stock; or

                  (iv) redeem or purchase or otherwise acquire for consideration
     any shares of Junior Preferred Stock, or any shares of stock ranking on a
     parity (either as to dividends or upon liquidation, dissolution or winding
     up) with the Junior Preferred Stock, except in accordance with a purchase
     offer made in writing or by publication (as determined by the Board of
     Directors) to all holders of such shares upon such terms as the Board of
     Directors, after consideration of the respective annual dividend rates and
     other relative rights and preferences of the respective series and classes,
     shall determine in good faith will result in fair and equitable treatment
     among the respective series or classes.

             (B)  The Company shall not permit any subsidiary of the Company to
     purchase or otherwise acquire for consideration any shares of stock of the
     Company unless the Company could, under paragraph (A) of this Section 4,
     purchase or otherwise acquire such shares at such time and in such manner.

     Section 5.   Reacquired Shares. Any shares of Junior Preferred Stock
purchased or otherwise acquired by the Company in any manner whatsoever shall be
retired and cancelled promptly after the acquisition thereof. All such shares
shall upon their cancellation become authorized but unissued shares of Preferred
Stock and may be reissued as part of a new series of Preferred Stock subject to
the conditions and restrictions on issuance set forth herein, in the Amended and
Restated Certificate of Incorporation, or in any other Certificate of
Designation creating a series of Preferred Stock or any similar stock or as
otherwise required by law.

     Section 6.   Liquidation, Dissolution or Winding Up.  Upon any liquidation,
dissolution or winding up of the Company, no distribution shall be made (1) to
the holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Junior Preferred Stock unless,
prior thereto, the holders of shares of Junior Preferred Stock shall have
received $100 per share, plus an amount equal to accrued and unpaid dividends
and distributions thereon, whether or not declared, to the date of such payment,
provided that the holders of shares of Junior Preferred Stock shall be entitled
to receive an aggregate amount per share, subject to the provision for
adjustment hereinafter set forth, equal to 100 times the aggregate amount to be
distributed per share to holders of shares of Common Stock, or (2) to the
holders of shares of stock ranking on a parity (either as to dividends or upon
liquidation, dissolution or winding up) with the Junior Preferred Stock, except
distributions made ratably on the Junior Preferred Stock and all such parity
stock in proportion to the total amounts to which the holders of all such shares
are entitled upon such liquidation, dissolution or winding up.  In the event the
Company shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
aggregate amount to which holders of shares of Junior 

                                       4

 
Preferred Stock were entitled immediately prior to such event under the proviso
in clause (1) of the preceding sentence shall be adjusted by multiplying such
amount by a fraction the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

      Section 7.  Consolidation, Merger, Etc. In case the Company shall enter
into any consolidation, merger, combination or other transaction in which the
shares of Common Stock are exchanged for or changed into other stock or
securities, cash and/or any other property, then in any such case each share of
Junior Preferred Stock shall at the same time be similarly exchanged or changed
into an amount per share, subject to the provision for adjustment hereinafter
set forth, equal to 100 times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is changed or exchanged. In the event the
Company shall at any time declare or pay any dividend on the Common Stock
payable in shares of Common Stock, or effect a subdivision or combination or
consolidation of the outstanding shares of Common Stock (by reclassification or
otherwise than by payment of a dividend in shares of Common Stock) into a
greater or lesser number of shares of Common Stock, then in each such case the
amount set forth in the preceding sentence with respect to the exchange or
change of shares of Junior Preferred Stock shall be adjusted by multiplying such
amount by a fraction, the numerator of which is the number of shares of Common
Stock outstanding immediately after such event and the denominator of which is
the number of shares of Common Stock that were outstanding immediately prior to
such event.

     Section 8.   No Redemption. The shares of Junior Preferred Stock shall 
not be redeemable.

     Section 9.   Rank. The Junior Preferred Stock shall rank, with respect 
to the payment of dividends and the distribution of assets, junior to all series
of any other class of the Company's Preferred Stock.

     Section 10.  Amendment. The Amended and Restated Certificate of
Incorporation of the Company shall not be amended in any manner which would
materially alter or change the powers, preferences or special rights of the
Junior Preferred Stock so as to affect them adversely without the affirmative
vote of the holders of at least two-thirds of the outstanding shares of Junior
Preferred Stock, voting together as a single class.
