                          CERTIFICATE OF DESIGNATION
                                      OF
                 SERIES A JUNIOR PARTICIPATING PREFERRED STOCK
                                      OF
                         TECHNOLOGY SOLUTIONS COMPANY

________________________________________________________________________________

                          Pursuant to Section 151 of
             the General Corporation Law of the State of Delaware

________________________________________________________________________________

          The undersigned do hereby certify that the following resolution was
duly adopted by the Board of Directors of Technology Solutions Company, a
Delaware corporation (the "Corporation"), on October 29, 1998:

          RESOLVED, that pursuant to the authority vested in the board of
directors of the Corporation by the Certificate of Incorporation, as amended
(the "Charter"), the Board of Directors does hereby create, authorize and
provide for the issue of a series of Preferred Stock, par value $.01 per share,
of the Corporation, to be designated "Series A Junior Participating Preferred
Stock" (hereinafter referred to as the "Series A Preferred Stock"), initially
consisting of 1,000,000 shares, and to the extent that the designations, powers,
preferences and relative and other special rights and the qualifications,
limitations or restrictions of the Series A Preferred Stock are not stated and
expressed in the Charter, does hereby fix and herein state and express such
designations, powers, preferences and relative and other special rights and the
qualifications, limitations and restrictions thereof, as follows (all terms used
herein which are defined in the Charter shall be deemed to have the meanings
provided therein):

          Section 1.  Designation and Amount.  The shares of such series shall
                      ----------------------
be designated as "Series A Junior Participating Preferred Stock" and the number
of shares constituting such series shall be 1,000,000.

          Section 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 prior and superior to the shares
of Series A Preferred Stock with

                                      -1-
<PAGE>

respect to dividends, the holders of shares of Series A Preferred 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 business day of January, April, July and October 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 Series A Preferred Stock, in an amount per
share (rounded to the nearest cent) equal to the greater of (a) $.01 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, par value $.01 per share, of the
Corporation (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 Series A
Preferred Stock. In the event the Corporation shall at any time after October
29, 1998 (the "Rights Declaration Date") (i) declare any dividend on Common
Stock payable in shares of Common Stock, (ii) subdivide the outstanding Common
Stock, or (iii) combine the outstanding Common Stock into a smaller number of
shares, then in each case the amount to which holders of shares of Series A
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 Corporation shall declare a dividend or distribution on the
Series A Preferred Stock as provided in paragraph (A) above immediately after it
declares a dividend or distribution on the Common Stock (other than a dividend
payable in shares of Common Stock); provided, however, 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, subject to the prior and superior rights of the
holders of any shares of any series of Preferred Stock ranking prior to and
superior to the shares of Series A Preferred Stock with respect to dividends, a
dividend of $.01 per share on the Series A Preferred Stock shall nevertheless by
payable on such subsequent Quarterly Dividend Payment Date.

          (C)  Dividends shall begin to accrue and be cumulative on outstanding
shares of Series A Preferred Stock from the

                                      -2-
<PAGE>

Quarterly Dividend Payment Date next preceding the date of issue of such shares
of Series A Preferred Stock, 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 Series
A 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 Series A 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 Series A Preferred Stock entitled to receive payment of
a dividend or distribution declared thereon, which record date shall be no more
than 60 days prior to the date fixed for the payment thereof.

          Section 3.  Voting Rights.
                      -------------

          The holders of shares of Series A Preferred Stock shall have the
following voting rights:

          (A)  Subject to the provision for adjustment hereinafter set forth,
each share of Series A Preferred Stock shall entitle the holder thereof to 100
votes on all matters submitted to a vote of the stockholders of the Corporation.
In the event the Corporation shall at any time after the Rights Declaration Date
(i) declare any dividend on Common Stock payable in shares of Common Stock, (ii)
subdivide the outstanding Common Stock, or (iii) combine the outstanding Common
Stock into a smaller number of shares, then in each such case the number of
votes per share to which holders of shares of Series A 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 or by law, the holders of
shares of Series A Preferred Stock and the holders of shares of Common Stock
shall vote collectively as one class on all matters submitted to a vote of
stockholders of the Corporation.

          (C)  (i)  If at any time dividends on any Series A Preferred Stock
     shall be in arrears in an amount equal to

                                      -3-
<PAGE>

     six (6) quarterly dividends thereon, the occurrence of such contingency
     shall mark the beginning of a period (herein called a "default period")
     which shall extend until such time when all accrued and unpaid dividends
     for all previous quarterly dividend periods and for the current quarterly
     dividend period on all shares of Series A Preferred Stock then outstanding
     shall have been declared and paid or set apart for payment. During each
     default period, all holders of Preferred Stock (including holders of the
     Series A Preferred Stock) with dividends in arrears in an amount equal to
     six (6) quarterly dividends thereon, voting as a class, irrespective of
     series, shall have the right to elect two (2) Directors.

          (ii)   During any default period, such voting right of the holders of
     Series A Preferred Stock may be exercised initially at a special meeting
     called pursuant to subparagraph (iii) of this Section 3(C) or at any annual
     meeting of stockholders, and thereafter at annual meetings of stockholders,
     provided that such voting right shall not be exercised unless the holders
     of ten percent (10%) in number of shares of Preferred Stock outstanding
     shall be present in person or by proxy.  The absence of a quorum of the
     holders of Common Stock shall not affect the exercise by the holders of
     Preferred Stock of such voting rights.  At any meeting at which the holders
     of Preferred Stock shall exercise such voting right initially during an
     existing default period, they shall have the right, voting as a class, to
     elect Directors to fill such vacancies, if any, in the Board of Directors
     as may then exist up to two (2) Directors or, if such right is exercised at
     an annual meeting, to elect two (2) Directors.  If the number which may be
     so elected at any special meeting does not amount to the required number,
     the holders of the Preferred Stock shall have the right to make such
     increase in the number of Directors as shall be necessary to permit the
     election by them of the required number.  After the holders of the
     Preferred Stock shall have exercised their right to elect Directors in any
     default period and during the continuance of such period, the number of
     Directors shall not be increased or decreased except by vote of the holders
     of Preferred Stock as herein provided or pursuant to the rights of any
     equity securities ranking senior to or pari passu with the Series A
                                            ---- -----
     Preferred Stock.

          (iii)  Unless the holders of Preferred Stock shall, during an existing
     default period, have previously exercised their right to elect Directors,
     the Board of Directors may order, or any stockholder or stockholders owning
     in the aggregate not less than ten percent (10%) of the total number of
     shares of Preferred Stock outstanding, irrespective of series, may request,
     the calling of special

                                      -4-
<PAGE>

     meeting of the holders of Preferred Stock, which meeting shall thereupon be
     called by the Chairman of the Board, the President, a Vice President or the
     Secretary of the Corporation. Notice of such meeting and of any annual
     meeting at which holders of Preferred Stock are entitled to vote pursuant
     to this paragraph (C)(iii) shall be given to each holder of record of
     Preferred Stock by mailing a copy of such notice to him or her at his or
     her last address as the same appears on the books of the Corporation. Such
     meeting shall be called for a time not earlier than 10 days and not later
     than 50 days after such order or request, or in default of the calling of
     such meeting within 50 days after such order or request, such meeting may
     be called on similar notice by any stockholder or stockholders owning in
     the aggregate not less than ten percent (10%) of the total number of shares
     of Preferred Stock outstanding. Notwithstanding the provisions of this
     paragraph (C)(iii), no such special meeting shall be called during the
     period within 50 days immediately preceding the date fixed for the next
     annual meeting of the stockholders.

          (iv)  In any default period, the holders of Common Stock, and, if
     applicable, other classes of capital stock of the Corporation, shall
     continue to be entitled to elect the whole number of Directors until the
     holders of Preferred Stock shall have exercised their right to elect two
     (2) Directors voting as a class, after the exercise of which right (x) the
     Directors so elected by the holders of Preferred Stock shall continue in
     office until their successors shall have been elected by such holders or
     until the expiration of the default period, and (y) any vacancy in the
     Board of Directors may (except as provided in paragraph (C)(ii) of this
     Section 3) be filled by vote of a majority of the remaining Directors
     theretofore elected by the holders of the class of capital stock which
     elected the Director whose office shall have become vacant.  References in
     this paragraph (C) to Directors elected by the holders of a particular
     class of stock shall include Directors appointed by such Directors to fill
     vacancies as provided in clause (y) of the foregoing sentence.

          (v)   Immediately upon the expiration of a default period, (x) the
     right of the holders of Preferred Stock as a class to elect Directors shall
     cease, (y) the term of any Directors elected by the holders of Preferred
     Stock as a class shall terminate, and (z) the number of Directors shall be
     such number as may be provided for in the certificate of incorporation or
     by-laws irrespective of any increase made pursuant to the provisions of
     paragraph (C)(ii) of this Section 3 (such number being subject, however, to
     change thereafter in any manner provided by law or in the certificate of
     incorporation or by-laws).  Any vacancies in

                                      -5-
<PAGE>

     the Board of Directors effected by the provisions of clauses (y) and (z) in
     the preceding sentence may be filled by a majority of the remaining
     Directors.

          (D)  Except as set forth herein, holders of Series A 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 Series A 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 Series A Preferred Stock outstanding shall have
been paid in full, the Corporation shall not:

          (i)  declare or pay dividends on, make any other distributions on, or
     redeem or purchase or otherwise acquire for consideration any shares of
     capital stock ranking junior (either as to dividends or upon liquidation,
     dissolution or winding up) to the Series A Preferred Stock;

          (ii)  declare or pay dividends on 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 Series A Preferred Stock,
     except dividends paid ratably on the Series A 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;

          (iii)  redeem or purchase or otherwise acquire for consideration
     shares of any capital stock ranking on a parity (either as to dividends or
     upon liquidation, dissolution or winding up) with the Series A Preferred
     Stock, provided that the Corporation may at any time redeem, purchase or
     otherwise acquire shares of any such parity stock in exchange for shares of
     any capital stock of the Corporation ranking junior (either as to dividends
     or upon dissolution, liquidation or winding up) to the Series A Preferred
     Stock; or

          (iv)  purchase or otherwise acquire for consideration any shares of
     Series A Preferred Stock, or any shares of capital stock ranking on a
     parity with the Series A Preferred Stock, except in accordance with a
     purchase offer made in writing or by publication (as

                                      -6-
<PAGE>

     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 Corporation shall not permit any subsidiary of the
Corporation to purchase or otherwise acquire for consideration any shares of
stock of the Corporation unless the Corporation 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 Series A Preferred Stock purchased or otherwise acquired
by the Corporation 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 to be created by resolution
or resolutions of the Board of Directors, subject to the conditions and
restrictions on issuance set forth herein.

          Section 6.  Liquidation, Dissolution or Winding Up.
                      --------------------------------------

          (A)  Upon any liquidation (voluntary or otherwise), dissolution or
winding up of the Corporation, no distribution shall be made to the holders of
shares of capital stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A 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
(the "Series A Liquidation Preference").  Following the payment of the full
amount of the Series A Liquidation Preference, no additional distributions shall
be made to the holders of shares of Series A Preferred Stock unless, prior
thereto, the holders of shares of Common Stock shall have received an amount per
share (the "Common Adjustment") equal to the quotient obtained by dividing (i)
the Series A Liquidation Preference by (ii) 100 (as appropriately adjusted as
set forth in subparagraph (C) below to reflect such events as stock splits,
stock dividends and recapitalizations with respect to the Common Stock) (such
number in clause (ii), the "Adjustment Number").  Following the payment of the
full amount of the Series A Liquidation Preference and the Common Adjustment in
respect of all outstanding shares of Series A Preferred Stock and Common Stock,
respectively, and the payment of liquidation preferences of all other shares of
capital stock

                                      -7-
<PAGE>

which rank prior to or on a parity with Series A Preferred Stock, holders of
Series A Preferred Stock and holders of shares of Common Stock shall receive
their ratable and proportionate share of the remaining assets to be distributed
in the ratio of the Adjustment Number to 1 with respect to such Preferred Stock
and Common Stock, on a per share basis, respectively.

          (B)  In the event, however, that there are not sufficient assets
available to permit payment in full of the Series A Liquidation Preference and
the liquidation preferences of all other series of Preferred Stock, if any,
which rank on a parity with the Series A Preferred Stock, then such remaining
assets shall be distributed ratably to the holders of such parity shares in
proportion to their respective liquidation preferences.  In the event, however,
that there are not sufficient assets available to permit payment in full of the
Common Adjustment, then such remaining assets shall be distributed ratably to
the holders of Common Stock.

          (C)  In the event the Corporation shall at any time after the Rights
Declaration Date (i) declare any dividend on Common Stock payable in shares of
Common Stock, (ii) subdivide the outstanding Common Stock, or (iii) combine the
outstanding Common Stock into a smaller number of shares, then in each such case
the Adjustment Number in effect immediately prior to such event shall be
adjusted by multiplying such Adjustment 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.

          Section 7.  Consolidation, Merger, etc.
                      --------------------------

          In case the Corporation 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 the shares of Series A 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 capital stock, securities, cash and/or any other
property (payable in kind), as the case may be, for which or into which each
share of Common Stock is exchanged or changed.  In the event the Corporation
shall at any time after the Rights Declaration Date (i) declare any dividend on
Common Stock payable in shares of Common Stock, (ii) subdivide the outstanding
Common Stock, or (iii) combine the outstanding Common Stock into a smaller
number of shares, then in each such case the amount set forth in the preceding
sentence with respect to the exchange or change of shares of Series A Preferred
Stock shall be adjusted by multiplying such amount by a fraction the numerator
of which is

                                      -8-
<PAGE>

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 Series A Preferred Stock shall not be redeemable.

          Section 9.  Ranking.
                      -------

          The Series A Preferred Stock shall rank junior to all other series of
the Corporation's Preferred Stock as to the payment of dividends and the
distribution of assets, whether or not upon the dissolution, liquidation or
winding up of the Corporation, unless the terms of any such series shall provide
otherwise.

          Section 10.  Amendment.
                       ---------

          The Charter shall not be amended in any manner which would materially
alter or change the powers, preferences or special rights of the Series A
Preferred Stock so as to affect them adversely without the affirmative vote of
the holders of a majority of the outstanding shares of Series A Preferred Stock,
voting separately as a class.

          Section 11.  Fractional Shares.
                       -----------------

          Series A Preferred Stock may be issued in fractions of a share which
shall entitle the holder, in proportion to such holder's fractional shares, to
exercise voting rights, receive dividends, participate in distributions and to
have the benefit of all other rights of holders of Series A Preferred Stock.

                      First Amendment to Rights Agreement

     First Amendment, dated as of February 9, 2000 (this "Amendment"), to Rights
Agreement, dated as of October 29, 1998 (the "Rights Agreement"), between
Technology Solutions Company, a Delaware corporation (the "Company"), and
ChaseMellon Shareholder Services, L.L.C., a New Jersey limited liability company
(the "Rights Agent").

                             W I T N E S S E T H :

     Whereas, the Board of Directors of the Company, at a meeting held on
January 26, 2000 and based in part on the recommendation of the Company's legal
advisors, has determined that it is advisable and in the best interest of the
Company to amend the Rights Agreement as set forth below;

     Whereas, at the date of this Amendment, the Distribution Date has not
occurred and there is no Acquiring Person; and

     Whereas, in compliance with Section 27 of the Rights Agreement, the Company
and the Rights Agent are willing to amend the Rights Agreement as hereinafter
set forth and the Company and the Rights Agent have each executed and delivered
this Amendment.

     Now, therefore, in consideration of the Rights Agreement and the premises
and mutual agreements herein set forth, the parties hereby agree as follows:

     1.  The second sentence of Section 1(a) of the Rights Agreement is hereby
amended and restated to read as follows:

          Notwithstanding the foregoing, no Person shall become an
          "Acquiring Person" as the result of an acquisition of shares
          of Common Stock by the Company which, by reducing the number
          of shares outstanding, increases the proportionate number of
          shares beneficially owned by such Person to 15% or more of
          the
<PAGE>

          shares of Common Stock then outstanding; provided, however,
          that if a Person shall become the Beneficial Owner of 15% or
          more of the shares of Common Stock then outstanding by
          reason of share purchases by the Company and shall, after
          such share purchases by the Company, become the Beneficial
          Owner of any additional shares of Common Stock (other than
          pursuant to a dividend or distribution paid or made by the
          Company on the outstanding Common Stock or pursuant to a
          split or subdivision of the outstanding Common Stock), then
          such Person shall be deemed to be an "Acquiring Person".

     2.  The last paragraph of Section 1 of the Rights Agreement is hereby
