                    (ii) Induce any person who is an employee, officer, agent,
               customer or supplier of Toyco.com or any of its subsidiaries to

               requirements, prices or other trade secrets of the Company or its
               subsidiaries, it being acknowledged by the Executive that all
               such information regarding the business of the Company and its
               subsidiaries, compiled or obtained by, or furnished to, the
               Executive while the Executive shall have been employed by or
               associated with the Company is confidential information and the
               Company's exclusive property. Upon termination of this Agreement,
               Executive shall promptly return to the Company all books,
               manuals, reports, client and customer lists, keys and other

               (b) All business ideas, concepts, inventions, improvements and
          developments made or conceived by the Executive during the Term of
          Employment and relating to the business of the Company or to any
          business or product the Company is actively considering entering or
          developing, shall become and remain the exclusive property of the
          Company, its successors and assigns.

               (c) The Executive expressly agrees and understands that the
          remedy at law for any breach by him of this Section 11 will be
          inadequate and that the damages flowing from such breach are not
          readily susceptible of being measured in monetary terms. Accordingly,
          it is acknowledged that upon adequate proof of the Executive's
          violation of any legally enforceable provision of this Section 11, the
          Company shall be entitled to seek immediate injunctive relief and may
          obtain a temporary order restraining any threatened or further breach.
          Nothing in this Section 11 shall be deemed to limit the Company's
          remedies at law or in equity for any breach by the Executive of any of
          the provisions of this Section 11 that may be pursued or availed of by
          the Company.

               (d) In the event that the Executive shall violate any legally
          enforceable provision of this Section 11 as to which there is a
          specific time period during which he is prohibited from taking certain
          actions or from engaging in certain activities, as set forth in such
          provision, then such violation shall toll the running of that time
          period from the date of its commencement until the date of its
          cessation.

               (e) The Executive has carefully considered the nature and extent
          of the restrictions upon him and the rights and remedies conferred
          upon the Company under this Section 11, and hereby acknowledges and
          agrees that the same (i) were a material inducement to the parties
          thereto in entering into the Contribution Agreement, and (ii) are
          reasonable in time and territory, are designed to eliminate
          competition that would otherwise be unfair to the Company, do not
          stifle the inherent skill and experience of the Executive, would not
          operate as a bar to the Executive's sole means of support, are fully
          required to protect the legitimate interests of the Company and do not
          confer a benefit upon the Company disproportionate to the detriment to
          the Executive.

         12.   WITHHOLDING TAXES. All payments to the Executive or his
beneficiary shall be subject to withholding on account of federal, state and
local taxes as required by law. If any payment hereunder is insufficient to
provide the amount of such taxes required to be withheld, the Company may
withhold such taxes from any other payment due the Executive or his beneficiary.
In the event all cash payments due the Executive are insufficient to provide the
required amount of such withholding taxes, the Executive or his beneficiary,
within five days after written notice from the Company, shall pay to the Company
the amount of such withholding taxes in excess of all cash payments due the
Executive or his beneficiary.

         13.   ASSIGNABILITY; BINDING NATURE. This Agreement shall be binding
upon and inure to the benefit of the Parties and their respective successors,
heirs (in the case of the Executive) and assigns. No rights or obligations of
the Company under this Agreement may be assigned or transferred by the Company
except that such rights or obligations may be assigned or transferred pursuant
to (a) a merger or consolidation in which the Company is not the continuing
entity or (b) a


                                      -7-

sale or liquidation of all or substantially all of the assets of the Company,
provided that the assignee or transferee is the successor to all or
substantially all of the assets of the Company and such assignee or transferee
assumes the liabilities, obligations and duties of the Company, as contained in
this Agreement, either contractually or as a matter of law. The Company further
agrees that, in the event of a sale of assets or liquidation as described in the
preceding sentence, it will use its best efforts to cause such assignee or
transferee expressly to assume the liabilities, obligations and duties of the
Company hereunder. No obligations of the Executive under this Agreement may be
assigned or transferred by the Executive.

         14.   ENTIRE AGREEMENT. Except to the extent otherwise provided herein,
this Agreement contains the entire understanding and agreement between the
Parties concerning the subject matter hereof and supersedes any prior
agreements, whether written or oral, between the Parties concerning the subject
matter hereof.

this Agreement.

         The liability of CSC under this Guaranty shall be irrevocable,

without limiting the generality thereof, CSC agrees that its liability with
respect to such obligations shall remain in full force and effect without
regard to, and shall not be impaired by, nor shall CSC be exonerated or
discharged by, (a) any insolvency, bankruptcy, reorganization, arrangement,
adjustment, composition, assignment for the benefit of creditors, liquidation,
winding up or dissolution of Toyco.com, CSC or any of its Affiliates; (b) any
limitation, discharge, or cessation of the liability of Toyco.com, CSC or its
Affiliates for any of the obligations due to any statute, regulation or rule of
law, or any invalidity or unenforceablity in whole or in part of any of the
obligations; (c) any merger, acquisition, consolidation or change in structure
of Toyco.com, CSC or its Affiliates, or any sale, lease, transfer or other
disposition of any or all of the assets or shares of Toyco.com, CSC or its
Affiliates; (d) any claim, defense, counterclaim or setoff, other than that of
prior performance, that Toyco.com, CSC or its Affiliates may have or assert,
including, without limitation any defense or incapacity or lack of corporate or
other authority to execute or deliver this Guaranty or any other document
related hereto; and (e) any direction of application pursuant to Toyco.com, CSC
or its Affiliates.
