                                       OF

                      SERIES A CONVERTIBLE PREFERRED STOCK

                                       OF

                          FIRSTWAVE TECHNOLOGIES, INC.

                   A GEORGIA CORPORATION (the "Corporation")

           ---------------------------------------------------------


         Twenty thousand (20,000) shares of the Corporation's Preferred Stock,
no par value per share, designated as "Series A Convertible Preferred Stock"
("Series A Preferred Stock"), are authorized for issuance with the voting
powers, preferences and other special rights, qualifications, limitations and
restrictions thereof set forth below:

     1. Dividends. Each holder of shares of Series A Preferred Stock shall be
entitled to receive, with respect to each share of Series A Preferred Stock
registered in his, her or its name on the stock transfer books of the
Corporation, cumulative dividends at a rate of $9 per annum. Dividends on
Series A Preferred Stock shall be paid annually on December 31 of each year to
holders of record as of December 15 of such year (except that any holder that
converts such holder's shares of Series A Preferred Stock pursuant to Section 3
hereof shall be paid, on the date of conversion, cumulative dividends dating
only through the last full fiscal quarter prior to the date of conversion),
shall accrue on each share beginning on the date of issuance, and shall be
cumulative. Dividends payable on the Series A Preferred Stock shall be paid in
cash or, at the election of the Corporation, in shares of the common stock, no
par value per share (the "Common Stock") of the Corporation. If the Corporation
elects to pay a dividend in shares of Common Stock, the number of shares of
Common Stock to be paid for each such dividend shall equal the number of shares
that could be purchased by an equivalent cash dividend at a price per share
equal to the average closing prices for the Common Stock for the last 20
trading days preceding the record date on the principal trading market for the
Common Stock. If there is no trading market for the Common Stock, the shares
shall be valued for this purpose in good faith by the Board of Directors of the
Corporation whose determination thereof shall be conclusive and binding on the
holders of Series A Preferred Stock. Any payment made by the Corporation on
unpaid cumulative dividends, if less than the total amount of such dividends,
shall be applied first to those dividends which have been accrued for the
longest time. No dividend or other distribution shall be paid on or declared or
set apart for payment on any shares of the Common Stock of the Corporation or
any shares of any other class or series or issue of preferred stock that


<PAGE>   3
is junior to Series A Preferred Stock as long as any accrued dividends on the
Series A Preferred Stock remain unpaid.

     2. Liquidation. Upon any liquidation, dissolution or winding up of the
Corporation, whether voluntary or involuntary, the holders of the shares of
Series A Preferred Stock shall be entitled, before any distribution or payment
is made upon the Common Stock or upon any other class or series or issue of
preferred stock of the Corporation that is junior to the Series A Preferred
Stock, to be paid an amount equal to $100 per share of Series A Preferred
Stock, plus all accrued but unpaid dividends (such amounts being herein
sometimes referred to as the "Liquidation Payments"). Thereafter, the holders
of the Series A Preferred Stock shall not be entitled to any further payment.
If upon such liquidation, dissolution or winding up of the Corporation, whether
voluntary or involuntary, the assets to be distributed to the holders of the
Series A Preferred Stock are insufficient to permit payment to the holders of
Series A Preferred Stock of the full amount of the Liquidation Payments, then
the entire assets of the Corporation to be distributed shall be distributed
ratably per share among the holders of Series A Preferred Stock. Upon any such
liquidation, dissolution or winding up of the Corporation, after the holders of
the Series A Preferred Stock have been paid in full the amounts to which they
are entitled, the remaining assets of the Corporation shall be distributed
ratably to the remaining holders of the Corporation's capital stock in
accordance with their respective rights and preferences under the Corporation's
Articles of Incorporation. The Corporation must give written notice of such
liquidation, dissolution or winding up (stating a payment date, the amount of
the Liquidation Payment and the place where said sums shall be payable) by
first class mail, postage prepaid, not less than 30 or more than 60 days prior
to the payment date stated therein, to the holders of record of the Series A
Preferred Stock and the Common Stock, such notice to be addressed to each
shareholder at its mailing address as shown by the records of the Corporation.
A sale, lease, exchange or transfer of all or substantially all of the assets
of the Corporation shall be regarded as a liquidation, dissolution or winding
up of the affairs of the Corporation within the meaning of this Section 2.

     3.  Conversion.

         3.1 Right to Convert. Subject to the terms and conditions of this
Section 3, the holder of any share or shares of Series A Preferred Stock shall
have the right, at such holder's option at any time after April 25, 2000, to
convert any such shares of Series A Preferred Stock (except that upon any
liquidation, dissolution or winding up of the Corporation the right of
conversion shall terminate at the close of business on the last full business
day preceding the date fixed for payment of the Liquidation Payments) into such
number of fully paid and nonassessable whole shares of Common Stock at a
conversion price determined by dividing $100 by $2.06 (the "Conversion Price")
(which equals 120% of the weighted average of the closing prices for the Common
Stock for the last 20 trading days prior to the subscription for the Series A
Preferred Stock for the holder thereof). If there is no trading market for the
Common Stock, the shares shall be valued for this purpose in good faith by the
Board of Directors of the Corporation whose determination thereof shall be
conclusive and binding on the holders of Series A Preferred Stock. Such rights
of conversion may be exercised by the holder thereof by giving written notice
to the Corporation that the holder elects to convert a stated number of shares
of Series A Preferred Stock into Common Stock and by surrender of a certificate
or certificates for the shares so to be 


                                       2
<PAGE>   4
converted to the Corporation at its principal office (or such other office or
agency of the Corporation as the Corporation may designate by notice in writing
to the holder or holders of the Series A Preferred Stock) at any time during
its usual business hours on the date set forth in such notice, together with a
statement of the name or names (with address), subject to compliance with
applicable laws to the extent such designation shall involve a transfer, in
which the certificate or certificates for shares of Common Stock are to be
issued. The number of whole shares of Common Stock into which the Preferred
Stock may be converted as determined hereinabove shall be adjusted to reflect
any recapitalization of the Common Stock of the Corporation, including as a
result of a stock dividend (other than shares of Common Stock paid to holders
of Series A Preferred Stock as dividend payments) or a stock split.

         3.2 Issuance of Certificates; Time Conversion Effected. Promptly after
the receipt by the Corporation of the written notice referred to in subsection
3.1 and the certificate or certificates for the share or shares of the Series A
Preferred Stock to be converted, the Corporation shall issue and deliver, or
cause to be issued and delivered, to the holder, registered in such name or
names as such holder may direct, subject to compliance with applicable laws to
the extent such designation shall involve a transfer, a certificate or
certificates for the number of whole shares of Common Stock issuable upon the
conversion of such share or shares of Series A Preferred Stock. To the extent
permitted by law, such conversion shall be deemed to have been effected and the
Conversion Price shall be determined as of the close of business on the date on
which the Corporation receives such written notice and the certificate or
certificates for such share or shares shall have been surrendered as aforesaid,
and at such time the rights of the holder of such share or shares of Series A
Preferred Stock shall cease (with respect to the shares of Series A Preferred
Stock), and 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 shares
represented thereby.

         3.3      Fractional Shares; Dividends; Partial Conversion.

                  (a) No fractional shares shall be issued upon conversion of
  the Series A Preferred Stock into Common Stock and the number of shares of
  Common Stock to be issued shall be rounded to the nearest whole share, and no
  payment or adjustment shall be made upon any conversion on account of any
  cash dividends on the Series A Preferred Stock so converted or the Common
  Stock issued upon such conversion. In case the number of shares of Series A
  Preferred Stock represented by the certificate or certificates surrendered
  pursuant to subsection 3.1 exceeds the number of shares converted, the
  Corporation shall, upon such conversion, execute and deliver to the holder
  thereof, at the expense of the Corporation, a new certificate or certificates
  for the number of shares of Series A Preferred Stock, represented by the
  certificate or certificates surrendered which are not to be converted.

                  (b) Upon conversion of any shares of Series A Preferred
  Stock, the holder of the shares of Series A Preferred Stock so converted
  shall be entitled to receive any dividends declared but unpaid with respect
  to such shares of Series A Preferred Stock provided that such dividends shall
  have been declared by the Board of Directors of the Corporation and the
  record date for such dividends shall have been on or before the date such
  shares shall have been



                                       3
<PAGE>   5
  converted. No payment or adjustment shall be made on account of dividends
  declared and payable to holders of Common Stock of record on a date prior to
  the date of conversion.

         3.4      Other Notices.  If at any time:

                 (a) the Corporation declares any dividend upon its Common
  Stock payable in cash or stock or makes any other distribution to the holders
  of the Common Stock;

                 (b) the Corporation offers for subscription pro rata to the
  holders of its Common Stock any additional shares of stock of any class or
  other rights;

                 (c) there is any reclassification of the capital stock of the
  Corporation, or a consolidation or merger of the Corporation with, or a sale
  of all or substantially all its assets to, another corporation; or

                 (d) there is a voluntary or involuntary dissolution,
  liquidation or winding up of the Corporation;

  then the Corporation shall give, by first class mail, postage prepaid,
  addressed to each holder of any shares of Series A Preferred Stock at the
  address of such holder as shown on the books of the Corporation, (a) at least
  15 days' prior written notice of the date on which the books of the
  Corporation shall close or a record shall be taken for such dividend,
  distribution or subscription rights or for determining rights to vote in
  respect of any such reorganization, reclassification, consolidation, merger,
  sale, dissolution, liquidation or winding up, and (b) in the case of any such
  reorganization, reclassification, consolidation, merger, sale, dissolution,
  liquidation or winding up, at least 15 days' prior written notice of the date
  when the same shall take place. Such notice in accordance with the foregoing
  clause (a) shall also specify, in the case of any such dividend, distribution
  or subscription rights, the date on which the holders of Common Stock shall be
  entitled thereto, and such notice in accordance with the foregoing clause (b)
  shall also specify the date on which the holders of Common Stock shall be
  entitled to exchange their Common Stock for securities or other property
  deliverable upon such reorganization, reclassification, consolidation, merger,
  sale, dissolution, liquidation or winding up, as the case may be.

         3.5 Stock to be Reserved. The Corporation must at all times reserve
  and keep available out of its authorized but unissued Common Stock, solely
  for the purpose of issuance upon the conversion of the Series A Preferred
  Stock as herein provided, such number of shares of Common Stock as shall then
  be issuable upon the conversion of all outstanding shares of Series A
  Preferred Stock. All shares of Common Stock which shall be so issued shall be
  duly and validly issued and fully paid and nonassessable and free from all
  taxes, liens and charges arising out of or by reason of the issue thereof,
  and, without limiting the generality of the foregoing, the Corporation
  covenants that it will from time to time take all such action as may be
  requisite to assure that the par value per share of the Common Stock is at
  all times equal to or less than the effective Conversion Price. The
  Corporation will take all such action within its control as may be necessary
  on its part to assure that all such shares of Common Stock may be so issued
  without violation of any applicable law or regulation, or of any requirement
  of any



                                       4
<PAGE>   6
  national securities exchange upon which the Common Stock of the Corporation
  may be listed. If at any time the number of authorized but unissued shares of
  Common Stock are insufficient to effect the conversion of all of the then
  outstanding shares of Series A Preferred Stock, the Corporation shall take
  such corporate actions as may be necessary to increase its authorized but
  unissued shares of Common Stock to such number of shares as shall be
  sufficient for such purposes.

         3.6 No Reissuance of Series A Preferred Stock. Shares of Series A
  Preferred Stock that are converted into shares of Common Stock as provided
  herein shall not be reissued.

         3.7 Issue Tax. The issuance of certificates for shares of Common Stock
  upon conversion of the Series A Preferred Stock shall be made without charge
  to the holders thereof for any issuance tax in respect thereof, provided that
  the Corporation shall not be required to pay any tax which may be payable in
  respect of any transfer involved in the issuance and delivery of any
  certificate in a name other than that of the holder of the Series A Preferred
  Stock which is being converted.

         3.8 Closing of Books. The Corporation will at no time close its
  transfer books against the transfer of any Series A Preferred Stock or of any
  shares of Common Stock issued or issuable upon the conversion of any shares
  of Series A Preferred Stock in any manner which interferes with the timely
  conversion of such Series A Preferred Stock.

         3.9 Definition of Common Stock. As used in this Section 3, the term
  "Common Stock" means and includes the Corporation's authorized Common Stock
  as constituted on the date of filing of this Certificate of Designation and
  shall also include any capital stock of any class of the Corporation
  thereafter authorized that shall not be limited to a fixed sum in respect of
  the rights of the holders thereof to participate in dividends or in the
  distribution of assets upon the voluntary or involuntary liquidation,
  dissolution or winding up of the Corporation; provided, however, that such
  term, when used to describe the securities receivable upon conversion of
  shares of the Series A Preferred Stock of the Corporation, shall include only
  shares designated as Common Stock of the Corporation on the date of filing of
  this Certificate of Designation.

     4. Voting. Except as otherwise provided by law and herein, the holders of
  Series A Preferred Stock shall vote together with the holders of Common Stock
  on all matters to be voted on by the shareholders of the Corporation, and
  each holder of Series A Preferred Stock shall be entitled to one vote for
  each share of Common Stock that would be issuable to such holder upon the
  conversion of all the shares of Series A Preferred Stock held by such holder
  on the record date for the determination of shareholders entitled to vote.

     5. Restrictions. At any time when shares of Series A Preferred Stock are
  outstanding, and in addition to any other vote of shareholders required by
  law or by the Corporation's Articles of Incorporation, without the prior
  consent of the holders of a majority of the outstanding Series A Preferred
  Stock, given in person or by proxy, either in writing, at an annual meeting
  or at a special meeting called for that purpose, at which meeting the holders
  of the shares of such Series A Preferred Stock shall vote together as a
  class:



                                       5
<PAGE>   7

                  (a)      The Corporation will not:

                           (i) create or authorize the creation of any
                  additional class or series of shares unless the same ranks
                  junior to the Series A Preferred Stock both as to dividends
                  and as to the distribution of assets on liquidation;

                           (ii) increase the authorized amount of the Series A
                  Preferred Stock, or increase the authorized amount of any
                  additional class or series of shares unless the same ranks
                  junior to the Series A Preferred Stock both as to dividends
                  and as to the distribution of assets on liquidation; or

                           (iii) create or authorize any obligations or
                  securities convertible into shares of Series A Preferred
                  Stock or into shares of any other class unless the same ranks
                  junior to the Series A Preferred Stock both as to dividends
                  and as to the distribution of assets on liquidation,

in each case whether any such creation or authorization or increase shall be by
means of amendment of the Corporation's Articles of Incorporation, merger,
consolidation or otherwise.

                  (b) The Corporation will not amend, alter or repeal the
  Corporation's Articles of Incorporation or Bylaws in any manner, or file any
  directors' resolutions pursuant to the Georgia Business Corporation Code
  containing any provision, in either case which affects the respective
  preferences, voting power, qualifications, special or relative rights or
  privileges of the Series A Preferred Stock or which in any manner adversely
  affects the Series A Preferred Stock or the holders thereof as a class.

     6.  Redemption.

         6.1 Call for Redemption. So long as dividends for all past dividend
periods shall have been paid on all outstanding shares of Series A Preferred
Stock prior to any notice of redemption being given and the full dividends
thereon for the then current dividend period shall have been paid or declared
and amounts sufficient for the payment thereof set aside (or shares of Common
Stock for such purpose shall have been reserved if the Corporation shall have
elected to pay such dividend in such shares), commencing April 26, 2001, and at
any time thereafter the Corporation, at the option of the Board of Directors,
may redeem in whole or in part the shares of Series A Preferred Stock at the
time outstanding, at any time or from time to time, upon notice given as
hereinafter specified, at a redemption price of $100 per share. In case of any
redemption of only a part of the shares of Series A Preferred Stock at the time
outstanding, the redemption shall be pro rata.

         6.2 Notice. Notice of redemption of shares of Series A Preferred Stock
shall be mailed by first class mail, postage prepaid, addressed to the holders
of record of the shares to be redeemed at their respective last addresses as
they shall appear on the books of the Corporation. Such mailing shall be at
least 20 days and not more than 60 days prior to the date fixed for redemption.
Any notice which is mailed in the manner herein provided shall be conclusively
presumed to have been duly given, whether or not the stockholder receives such
notice, but 



                                       6
<PAGE>   8
  failure duly to give such notice by mail, or any defect in such notice or in
  the mailing thereof, to any holder of shares of Series A Preferred Stock
  designated for redemption shall not affect the validity of the proceedings
  for the redemption of any other shares of Series A Preferred Stock.

         6.3 Procedure. If such notice of redemption shall have been duly given
  or if the Corporation shall have given to the bank or trust company
  hereinafter referred to irrevocable authorization promptly to give such
  notice, and if on or before the redemption date specified therein all funds
  necessary for such redemption shall have been 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, or, at the option of the Corporation, deposited by the
  Corporation with such bank or trust company in trust for the pro rata benefit
  of the holders of the shares called for redemption, then, notwithstanding
  that any certificate for shares so called for redemption shall not have been
  surrendered for cancellation, on and after such redemption date, all shares
  so called for redemption, not theretofore converted and outstanding on the
  redemption date, shall no longer be deemed to be outstanding and all rights
  with respect to such shares shall forthwith on such redemption date cease and
  terminate, except only the right of the holders thereof to receive the amount
  payable on redemption thereof, without interest. The aforesaid bank or trust
  company shall be organized and in good standing under the laws of the United
  States of America or of the State of Georgia, shall be doing business in
  Georgia, and shall be identified in the notice of redemption. Any interest
  accrued on such funds shall be paid to the Corporation from time to time. Any
  funds so deposited and unclaimed at the end of three years from the
  redemption date shall, to the extent permitted by law, be released or repaid
  to the Corporation, after which time the holders of the shares so called for
  redemption shall look only to the Corporation for payment thereof. Any funds
  so deposited or set aside by the Corporation which shall not be required for
  such redemption because of the exercise of any right of conversion pursuant
  to Section 3 hereof shall be released or repaid to the Corporation forthwith.
