                         TECHNOLOGY SOLUTIONS COMPANY
                   (as amended and restated March 24, 2000)

                       1995 EMPLOYEE STOCK PURCHASE PLAN
                       ---------------------------------

1.   Purpose.  The purpose of the Technology Solutions Company 1995 Employee
Stock Purchase Plan (the "Plan") is to provide employees of Technology Solutions
Company, a Delaware corporation (the "Company"), and its Subsidiary Companies
(as defined in Section 15) added incentive to remain employed by such companies
and to encourage increased efforts to promote the best interests of such
companies by permitting eligible employees to purchase shares of the common
stock, par value $.01, of the Company ("Common Stock") at below-market prices.
The Plan is intended to qualify as an "employee stock purchase plan" under
section 423 of the Internal Revenue Code of 1986, as amended (the "Code"). The
Company and its Subsidiary Companies are sometimes hereinafter called
individually a "Participating Company" or collectively the "Participating
Companies."

2.   Eligibility.  Participation in the Plan shall be open to each employee of
the Participating Companies (a) who has been continuously employed by the
Participating Companies for at least three months, (b) whose customary
employment by the Participating Companies is greater than 20 hours per week; and
(c) whose customary employment by the Participating Companies is more than 5
months in any calendar year (each an "Eligible Employee"). No right to purchase
Common Stock hereunder shall accrue under the Plan in favor of any person who is
not an Eligible Employee as of the first day of a Purchase Period (as defined in
Section 3). Notwithstanding anything contained in the Plan to the contrary, no
Eligible Employee shall acquire a right to purchase Common Stock hereunder (i)
if, immediately after receiving such right, such employee would own 5% or more
of the total combined voting power or value of all classes of stock of the
Company or any Subsidiary Company (including any stock attributable to such
employee under section 424(d) of the Code), or (ii) if for a given calendar year
such right would permit such employee's aggregate rights to purchase Common
Stock under all employee stock purchase plans of the Company and its Subsidiary
Companies (which aggregate rights are exercisable during such calendar year) to
accrue at a rate which exceeds $25,000 of fair market value of such Common Stock
for such calendar year, all determined in the manner provided by section
423(b)(8) of the Code and the rules and regulations thereunder. In addition, the
number of shares of Common Stock which may be purchased by any Eligible Employee
during any Purchase Period shall not exceed 1,500, subject to adjustment
pursuant to Section 14.

3.   Effective Date of Plan.  The Plan shall become effective on October 1,
1995, or on such later date (the "Effective Date") as may be specified by the
Board of Directors (the "Board") of the Company or the Committee (as defined in
Section 12). The Plan shall cease to be effective unless, within 12 months
before or after the date of its adoption by the Board, it has been approved by
the stockholders of the Company in accordance with the General Corporation Law
of the State of Delaware.

4.   Purchase Periods.  The first "Purchase Period" shall be for a three month
period beginning on October 1, 1995 and ending on January 31, 1996, and shall be
followed thereafter
<PAGE>

by successive three-month Purchase Periods, each of which shall begin on the
first business day following the end of the last Purchase Period and end on the
last business day of the third month thereafter. In the event of a pro rata
distribution by the Company to its stockholders of all of the shares of the
common stock of eLoyalty Corporation then owned by the Company (a "Spin-Off"),
the Purchase Period then in effect under the Plan shall end as of the business
day immediately preceding the record date of the Spin-Off. The amounts credited
to the Purchase Accounts of all Participants as of such date shall be applied to
purchase shares of Common Stock in accordance with Section 5 of the Plan, and
such shares shall be considered issued and outstanding for purposes of the Spin-
Off. Thereafter, a new Purchase Period shall begin on the first business day
after the record date of the Spin-Off (the "Record Date") and end on the last
business day of the calendar quarter in which the Record Date occurs (or on the
last business day of the first calendar quarter beginning after the Record Date,
if so determined by the Committee prior to the Record Date in its sole
discretion). Such Purchase Period shall be followed by successive three-month
Purchase Periods, each of which shall begin on the first business day of the
following calendar quarter and end on the last business day of such calendar
quarter.

5.   Basis of Participation.
     ----------------------

     (a)  Each Eligible Employee shall be entitled to enroll in the Plan as of
the first day of any Purchase Period which begins on or after such employee
becomes an Eligible Employee and shall be considered a Participant in the Plan
thereafter ("Participant").

          (i)  To enroll in the Plan, an Eligible Employee shall execute and
     deliver a payroll deduction authorization (the "Authorization") to the
     Participating Company which is the employee's employer, or its designated
     agent, in the time and manner specified by the Committee. The Authorization
     shall become effective on the first day of the Purchase Period commencing
     after the execution and delivery of such Authorization. Each Authorization
     shall direct that payroll deductions be made by the Participating Company
     which is the employee's employer for each payroll period during which the
     employee is a Participant in the Plan. The amount of each payroll deduction
     specified in an Authorization for each such payroll period shall be a whole
     percentage amount or a whole dollar amount, as determined by the Committee,
     in either case not to exceed 15%, or such lesser percentage as may be
     determined by the Committee, of the Participant's current regular wage or
     salary (before withholding or other deductions) paid to him or her by any
     of the Participating Companies.

          (ii)  Payroll deductions (and any other amount paid under the Plan)
     shall be made for each Participant in accordance with his or her or her
     Authorization until his or her or her participation in the Plan terminates
     or the Plan terminates, all as hereinafter provided. Payroll deductions
     (and any other amount paid under the Plan) shall continue in accordance
     with such Authorization notwithstanding any transfer of employment between
     Participating Companies.

          (iii)  A Participant may change the amount of his or her payroll
     deduction by filing a new Authorization with the Company or its designed
     agent, which shall become effective on the first day of the Purchase Period
     commencing after the execution and delivery of such Authorization. No other
     changes shall be permitted, except that a

                                       2
<PAGE>

     Participant may elect to terminate his or her participation in the Plan as
     provided in Section 8.

          (iv)  Payroll deductions shall be credited to a purchase account
     established on the books of the Company on behalf of each Participant (a
     "Purchase Account"). At the end of each Purchase Period, the amount in each
     Participant's Purchase Account will be applied to the purchase from the
     Company of the number of shares of Common Stock determined by dividing such
     amount by the Purchase Price (as defined in Section 6) for such Purchase
     Period.

     (b)  The Committee may, in its discretion, establish additional procedures
whereby Eligible Employees may participate in the Plan by means other than
payroll deduction, including, but not limited to, delivery of funds by
Participants in a lump sum or automatic charges to Participants' bank accounts.
Such other methods of participating shall be subject to such rules and
conditions as the Committee may establish. The Committee may at any time amend,
suspend to terminate any participation procedures established pursuant to this
paragraph without prior notice to any Participant or Eligible Employee.

6.   Purchase Price.  The purchase price (the "Purchase Price") per share of
Common Stock hereunder for any Purchase Period shall be 85% of the lesser of (i)
the fair market value of a share of Common Stock on the first day of such
Purchase Period and (ii) the fair market value of a share of Common Stock on the
last day of such Purchase Period, unless, prior to the beginning of such
Purchase Period, the Committee shall determine otherwise (subject to the
limitations contained in clause (iii) of Section 9(c)). If such determination
results in a fraction of one cent, the Purchase Price shall be increased to the
next higher full cent. The fair market value of a share of Common Stock on a
given day shall be the average of the high and low transaction prices of a share
of Common Stock as reported on The Nasdaq Stock Market on the date as to which
such value is being determined or, if there shall be no reported transactions on
such date, on the next preceding date for which transactions were reported. In
no event, however, shall the Purchase Price be less than the par value of the
Common Stock.

7.   Issuance of Shares.
     ------------------

     (a)  The Common stock purchased by each Participant shall be considered to
be issued and outstanding to his or her credit as of the close of business on
the last day of each Purchase Period. The total number of shares of Common Stock
purchased by all Participants during each Purchase Period shall be issued, as of
the last day in such Purchase Period, to a nominee or agent for the benefit of
the Participants. A Participant will be issued a certificate for his or her
shares upon the request of the Participant in accordance with the procedures
established by the Company.

     (b)  No interest shall accrue at any time for any amount credited to a
Purchase Account of a Participant. After the close of each Purchase Period, a
report will be sent to each Participant stating the entries made to his or her
Purchase Account, the number of shares of Common Stock purchased and the
applicable Purchase Price.

                                       3

8.   Termination of Participation.
     ----------------------------

     (a)  A Participant may elect at any time to terminate his or her
participation in the Plan, provided such termination is received by the Company
in writing prior to the last business day of the Purchase Period for which such
termination is to be effective. Upon any such termination, the Company shall
promptly deliver to such Participant cash in an amount equal to the balance to
his or her credit in his or her Purchase Account on the date of such
termination. At any time after such termination, the Participant may request the
delivery to such Participant of one or more certificates for the number of whole
shares of Common Stock held for his or her benefit, and the cash equivalent for
any fractional share so held. Such cash equivalent shall be determined by
multiplying the fractional share by the fair market value of a share of Common
Stock on the last day of the Purchase Period immediately preceding such
termination, determined as provided in Section 6.

     (b)  If the Participant dies, terminates his or her employment with the
Participating Companies for any reason, or otherwise ceases to be an Eligible
Employee (including, without limitation, as a result of a Participating Company
ceasing to be a Subsidiary Company), his or her participation in the Plan shall
immediately terminate. Upon such terminating event, the Company shall promptly
deliver to such Participant or his or her legal representative, as the case may
be, cash in an amount equal to the balance to his or her credit in his or her
Purchase Account on the date of such termination.

9.   Termination or Amendment of the Plan.
     ------------------------------------

     (a)  The Company, by action of the Board or the Committee, may terminate
the Plan at any time. Notice of termination shall be given to all Participants,
but any failure to give such notice shall not impair the effectiveness of the
termination.

     (b)  Without any action being required, the Plan will terminate in any
event when the maximum number of shares of Common Stock to be sold under the
Plan (as provided in Section 13) has been purchased. Such termination shall not
impair any rights which under the Plan shall have vested on or prior to the date
of such termination. If at any time the number of shares remaining available for
purchase under the Plan are not sufficient to satisfy all then-outstanding
purchase rights, the Board may determine an equitable basis of apportioning
available shares among all Participants consistent with Section 423 of the Code.

     (c)  The Board or the Committee may amend the Plan from time to time in any
respect for any reason; provided, however, no such amendment shall (i)
materially adversely affect any purchase rights outstanding under the Plan
during the Purchase Period in which such amendment is to be effected, (ii)
unless approved by the stockholders of the Company, increase the maximum number
of shares of Common Stock which may be purchased under the Plan (iii) decrease
the Purchase Price of the shares of Common Stock for any Purchase Period below
the lesser of 85% of the fair market value thereof on the first day of such
Purchase Period and 85% of the fair market value thereof on the last day of such
Purchase Period, (iv) unless approved by the stockholders of the Company, change
the class of employees eligible to participate in the Plan or (v) adversely
affect the qualification of the Plan under Section 423 of the Code.

                                       4
<PAGE>

     (d)  Upon termination of the Plan, the respective cash balance, if any, to
the credit of each Participant in his or her Purchase Account, one or more
certificates for the number of whole shares of Common Stock held for his or her
benefit, and the cash equivalent of any fractional shares so held, determined as
provided in Section 8(a), shall be promptly distributed to such Participant.

10.  Non-Transferability.  Rights acquired under the Plan are not transferable
and may be exercised only by a Participant.

11.  Stockholder's Rights.  No Eligible Employee or Participant shall by reason
of the Plan have any rights of a stockholder of the Company until and to the
extent he or she shall acquire shares of Common Stock as herein provided.

12.  Administration of the Plan.
     --------------------------

     (a)  The Plan shall be administered by the Compensation Committee of the
Board (the "Committee"), provided that the Board may otherwise appoint (i) the
entire Board or (ii) a committee consisting of two or more members of the Board,
to act as the Committee. In addition to the power to amend or terminate the Plan
pursuant to Section 9, the Committee shall have full power and authority to: (A)
interpret and administer the Plan and any instrument or agreement entered into
under the Plan; (B) establish such rules and regulations and appoint such agents
as it shall deem appropriate for the proper administration of the Plan; and (C)
make any other determination and take any other action that the Committee deems
necessary or desirable for administration of the Plan. Decisions of the
Committee shall be final, conclusive and binding upon all persons, including the
Company, any Participant and any other employee of the Company. A majority of
the members of the Committee may determine its actions and fix the time and
place of its meetings.

     (b)  The Plan shall be administered so as to ensure all Participants have
the same rights and privileges as required by section 423(b)(5) of the Code.

13.  Maximum Number of Shares.  The maximum number of shares of Common Stock
which may be purchased under the Plan is 3,687,500, subject, however, to
adjustment as hereinafter set forth. If the Company shall, at any time after the
Effective Date, change its issued Common Stock into an increased number of
shares through a stock dividend or a split-up of shares, or into a decreased
number of shares through a combination of shares, then, effective with the
record date for such change, the maximum number of shares of Common Stock which
thereafter may be purchased under the Plan shall be the maximum number of shares
of Common Stock which, immediately prior to such record date, remained available
for purchase under the Plan proportionately increased, in case of such stock
dividend or split-up, or proportionately decreased in cash of such combination
of shares.

14.  Adjustment.  In the event of any stock split, stock dividend,
recapitalization, reorganization, merger, consolidation, combination, exchange
of shares, liquidation, spin-off or other similar change in capitalization or
event, or any distribution to holders of Common Stock other than a regular cash
dividend, the maximum number and class of securities which may purchased under
this Plan, the maximum number and class of securities that may be purchased

                                       5
<PAGE>

by any Eligible Employee during any Purchase Period, and the purchase price per
security shall be appropriately adjusted by the Committee. The decision of the
Committee regarding any such adjustment shall be final, binding and conclusive.
If any such adjustment would result in a fractional security being available
under this Plan, such fractional security shall be disregarded.

15.  Miscellaneous.

     (a)  Except as otherwise expressly provided herein, any Authorization,
election, notice or document under the Plan from an Eligible Employee or
Participant shall be delivered to the Company, the Participating Company that is
the employer of such Eligible Employee, or their designated agents and, subject
to any limitations specified in the Plan, shall be effective when so delivered.

     (b)  The term "business day" shall mean any day other than Saturday, Sunday
or a legal holiday recognized by the Participating Corporation for which the
Participant is employed.

     (c)  The term "Exchange Act" shall mean the Securities Exchange Act of
1934, as amended.

     (d)  The term "Subsidiary Companies" shall mean all corporations which are,
or become, after the Effective Date, subsidiary corporations (within the meaning
of Section 424(f) of the Code) and of which the Company is the common parent.

     (e)  The Plan, and the Company's obligation to sell and deliver Common
Stock hereunder, shall be subject to all applicable federal, state and foreign
laws, rules and regulations, and to such approval by any regulatory or
governmental agency as may, in the opinion of counsel for the Company, be
required.

16.  Change in Control.

     (a)  In order to maintain the Participants' rights in the event of any
Change in Control of the Company, as hereinafter defined, upon such Change in
Control, the then current Purchase Period shall thereupon end, and all
Participants' Purchase Accounts shall be applied to purchase shares of Common
Stock pursuant to Section 6, and the Plan shall immediately thereafter
terminate.

     (b)  "Change in Control" for the purposes hereof means the occurrence of
any of the following events:

          (i)  the acquisition by any individual, entity or group (a "Person"),
     including any "person" within the meaning of Section 13(d)(3) or 14(d)(2)
     of the Exchange Act, of beneficial ownership within the meaning of Rule
     13d-3 promulgated under the Exchange Act, of 35% or more of either (A) the
     then outstanding shares of common stock of the Company (the "Outstanding
     Company Common Stock") or (B) the combined voting power of the then

     Voting Securities by reason of an acquisition by the Company, and such
     Person shall, after such acquisition by the Company, become the beneficial
     owner of any additional shares of the Outstanding Company Common Stock or
     any additional Outstanding Company Voting Securities and such beneficial
     ownership is publicly announced, such additional beneficial ownership shall

     director of the Company subsequent to the date hereof whose election, or

     Board, shall be deemed a member of the Incumbent Board; and provided
     further, that any individual who was initially elected as a director of the

     terms are used in Rule 14a-11 of Regulation 14A promulgated under the
     Exchange Act, or any other actual or threatened solicitation of proxies or

     of, respectively, the outstanding shares of common stock and the combined
     voting power of the outstanding securities entitled to vote generally in

     from such Corporate Transaction (including, without limitation, a
     corporation which, as a result of such transaction, owns the Company or all
     or substantially all of the Company's assets either directly or indirectly)
     in substantially the same proportions relative to each other as their

for a period of time after they are purchased under the Plan in order to make it

          4. Effective as of the first day of the first Purchase Period
beginning after the date hereof, Section 8(a) of the Plan is hereby amended by
deleting the third sentence thereof and inserting the following sentence in lieu
thereof:
