                             COMPENSATION AGREEMENT

               This COMPENSATION AGREEMENT, dated April 26, 2002, by and between
ROTARY POWER INTERNATIONAL, INC. (the "Client") and ONE EIGHTY ASSOCIATES LLC
("One Eighty").

               WHEREAS, One Eighty has heretofore provided various marketing and
management consulting services to the Client; and

               WHEREAS, One Eighty and the Client desire to enter into this
Agreement in order to set forth the compensation which One Eighty shall receive
for such services.

               NOW, THEREFORE, in consideration of the premises and of the
covenants made herein and of the mutual benefits to be derived herefrom, the
parties hereto, intending to be legally bound, agree as follows:

               1. The Client acknowledges and agrees that One Eighty has
heretofore rendered bona fide marketing and management consulting services to
the Client pursuant to an Engagement Letter dated December 3, 2001 (the
"Engagement Letter"), by and between the Client and One Eighty. The services
rendered by One Eighty pursuant to the Engagement Letter consisted of, among
other things, a review of the Client's business plan and strategy, an
examination of potential business combinations and strategic alliances for the
Client and a review of the market potential of certain products of the Client.
The Client and One Eighty acknowledge and agree that the services previously
rendered by One Eighty as described in the preceding sentence did not include
any consulting or other services in connection with the offer or sale of the
Client's securities in a capital raising transaction and did not, directly or
indirectly, promote or maintain a market for the Client's securities.

               2. Pursuant to a Settlement Agreement dated as of March 14, 2002
(the "Settlement Agreement") and a Letter Agreement dated April 9, 2002 (the
"Letter Agreement"), the Client and One Eighty agreed to settle all claims among
them relating to the Engagement Letter upon the payment to One Eighty of $50,000
in cash by no later than April 30, 2002. One Eighty hereby acknowledges that it
has previously received $25,000 from the Client in payment of the amounts
required by the Settlement Agreement and the Letter Agreement and that $25,000
is the remaining outstanding balance as of the date hereof.

               3. In satisfaction of the outstanding $25,000 balance, the Client
shall issue, and One Eighty agrees to accept, on the terms and conditions set
forth in this paragraph, 100,000 shares of the Client's common stock (the
"Shares"), which Shares shall be issued to Jonathan S. Hayes, a member of One
Eighty who actually rendered a substantial portion of One Eighty's services
described in paragraph 1 above, on or before April 30, 2002. The Shares, when
issued, shall be registered under the Securities Act of 1933, as amended,
pursuant to a registration statement filed by the Client with the Securities and
Exchange Commission on Form S-8 (or, if Form S-8 is not then available, such
other form of registration statement then available for the registration of the
Shares). Any and all costs of filing such registration statement for the Shares
shall be the responsibility of the Client.

               4. If for any reason the Shares are not issued to Jonathan S.
Hayes on or before April 30, 2002, the Settlement Agreement, the Letter
Agreement and this Agreement shall be null and void and of no further force or
effect, and One Eighty will retain, and be restored to, all rights it had under
the Engagement Letter.

Second Amendment to Rights Agreement    
  

        Second Amendment, dated as of April 25, 2002 (this "Amendment"), to Rights Agreement, dated as of October 29, 1998, as amended as of
February 9, 2000 (the "Rights Agreement"), between Technology Solutions Company, a Delaware corporation (the "Company"), and Mellon Investor Services LLC, a New Jersey limited liability company
(successor to ChaseMellon Shareholder Services, L.L.C.), as Rights Agent (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 April 25, 2002, has determined that it
is advisable and in the best interest of the Company to amend the Rights Agreement as set forth below; 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
first and second sentences of Section 1(a) of the Rights Agreement are hereby amended and restated to read as follows: 

"Acquiring
Person" shall mean (i) any Person, other than the State of Wisconsin Investment Board ("SWIB"), who or which, together with all Affiliates and Associates of such Person, shall be the
Beneficial Owner of 15% or more of the shares of Common Stock then outstanding, or (ii) SWIB on such date as it, together with all of its Affiliates and Associates, shall be the Beneficial
Owner of 20% or more of the shares of Common Stock then outstanding, but shall not include the Company, any Subsidiary of the Company, any employee benefit plan of the Company or any Subsidiary of the
Company, or any Person organized, appointed or established by the Company for or pursuant to the terms of any such plan. 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 (20% or more in the case of SWIB) of the shares of Common Stock then outstanding; provided, however, that if a Person shall become the Beneficial Owner of 15% or more (20% or
more in the case of SWIB) 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 amended by inserting the new clause "(xxi) "SWIB" shall have the meaning set forth in
Section 1(a)" and renumbering the current clause (xxi) to (xxii). 

        3.    The
first sentence of Section 3(a) of the Rights Agreement is hereby amended by adding the parenthetical phrase "(20% or more in the case of SWIB)" immediately
after the phrase "15% or more". 

        4.    The
last sentence of the first paragraph of the Summary of Rights to Purchase Preferred Stock attached as Exhibit C
to the Rights Agreement is hereby amended and restated to read as follows: 

The
description and terms of the Rights are set forth in a Rights Agreement, dated as of October 29, 1998, as amended by the First Amendment, dated as of February 9, 2000, and the Second
Amendment, dated as of April 25, 2002 (collectively, the "Rights Agreement"), 

 

between the Company and Mellon Investor Services LLC, a New Jersey limited liability company (successor to ChaseMellon Shareholder Services, L.L.C.), as Rights Agent. 

        5.    The
second paragraph of the Summary of Rights to Purchase Preferred Stock attached as Exhibit C to the Rights
Agreement is hereby amended and restated to read as follows: 

Initially,
the Rights will be attached to all Common Stock certificates representing shares then outstanding, and no separate Rights certificates will be distributed. The Rights will separate from the
Common Stock and the Distribution Date will occur upon the earlier of (i) 10 days following a public announcement that a person or group of affiliated or associated persons (an
"Acquiring Person") has
acquired, or obtained the right to acquire, beneficial ownership of 15% or more (20% or more if the person is the State of Wisconsin Investment Board ("SWIB")) of the outstanding shares of Common
Stock (the "Stock Acquisition Date") or (ii) 10 business days (or such later date as may be determined by action of the Board of Directors prior to such time as any person or group becomes an
Acquiring Person) following the commencement of a tender offer or exchange offer which, if consummated, would result in a person or group beneficially owning 15% or more (20% or more in the case of
SWIB) of the outstanding shares of Common Stock. 

        6.    This
Amendment shall be deemed to be a contract made under the laws of the State of Delaware and for all purposes shall be governed by and construed with in accordance
with the laws of such State applicable to contracts to be made and performed entirely within such State. 

        7.    This
Amendment may be executed in two or more counterparts, each of which shall for all purposes be deemed to be an original, but all such counterparts shall together
constitute one and the same instrument. 

        8.    Any
capitalized term used herein without definition shall have the meaning specified in the Rights Agreement. 

        9.    Except
as otherwise expressly set forth herein, this Amendment shall not by implication or otherwise alter, modify, amend or in any other manner affect any of the terms,
conditions, obligations, covenants or agreements contained in the Rights Agreement, all of which are hereby ratified and confirmed in all respects and shall continue in full force and effect.
