Section 7 - Indemnification/Insurance.

that all Intellectual Property relating to the Business developed by the
Employee during Employee's employment that is subject to copyright protection
shall be deemed "work made for hire" pursuant to the Copyright Act, as amended,
17 U.S.C. ss. 101, et seq. and shall be the sole property of Company. Provided,
further, that, to the extent that any Intellectual Property relating to the
Business, that is subject to protection under the Copyright Act, is not deemed
"work-for-hire," Employee hereby assigns to Company all rights that the Employee
may have or acquire with respect to such Intellectual Property, including all
copyright rights with respect thereto. Employee further hereby assigns to
Company all patent and all other ownership rights to the Intellectual Property
to Company. Employee hereby agrees to execute any and all documents necessary to
carry out the aforesaid assignment. Employee further agrees that if Employee
fails to execute any such documents or is unavailable at the time necessary for
such execution, Company is hereby appointed as Employee's attorney-in-fact for
the purpose of executing such documents.

Section 9 - Termination.
------------------------

         In addition to the termination provisions set forth in Section 6 of
this Agreement, the Company may terminate this Agreement at any time with or
without "cause". If the Company terminates Employee's employment for reasons
other than "cause", Employee shall be entitled to a lump-sum severance payment
equal to the payments and benefits under this contract on the remaining
Employment Term, but in no event less than 6 months. No severance pay is due
under this Agreement if Employee terminates his employment voluntarily or is
terminated for "cause". Any termination by the Employee for Good Reason shall be
deemed to be a termination by the Company without "cause." Employee acknowledges
that the potential severance payment hereunder is attributable, in part, to his
agreement to the noncompetition provision set forth in Section 8, which is
applicable regardless of the reason for his termination of employment.

         For purposes of this Section 9, "Cause" will mean (i) fraud,
embezzlement, theft, or misappropriation of funds or other property of the
Company or any Company Affiliate; (ii) gross negligence in the performance by
the Employee of his duties pursuant to this Agreement; or the willful failure or
refusal by the Employee to perform his duties to the

                                       5
<PAGE>

Company as provided herein, which gross negligence, failure or refusal is not
corrected within 30 days after notice from the Board of Directors; (iii) the
conviction of the Employee of a felony or other criminal act involving
dishonesty, whether or not relating to his employment with the Company; ; or
(iv) the breach by the Employee of any of the restrictive covenants contained in
Section 10 or covenants of non-disclosure contained in Section 11 of this
Agreement. Any termination of the Employee's employment by reason of the
activities or events described in the prior sentences will not be in limitation
of any other right or remedy which the Company may have under this Agreement, at
law, or in equity.

         Should Employee's termination for reasons other than "cause" occur
within a two-year period after a "Change-in-Control," Employee shall be entitled
to a lump-sum severance payment equal to two (2) years' Base Salary. A "Change
in Control" means the occurrence during the Employment Term of the following
events:

                  (i)      the Company merges or consolidates with, another
                           entity and as a result of such merger or
                           consolidation less than 51% of the voting power of
                           the then-outstanding voting securities of the
                           surviving or resulting entity immediately after such
                           transaction are directly or indirectly beneficially
                           owned in the aggregate by the former stockholders of
                           the Company immediately prior to such transaction;

                  (ii)     a person or group acting in concert within the
                           meaning of Section 3(a)(9) or 13(3)(3) (as in effect
                           on the date of this Agreement) of the Securities
                           Exchange Act of 1934, becomes the beneficial owner
                           (as defined in Rule 13d-3) of 50% or more of the
                           voting power of the then outstanding voting
                           securities of the Company without prior approval of
                           the Company's Board of Directors; provided that the
                           foregoing shall not apply to any existing ownership
                           interest of more than 50% of the Company's Common
                           Stock;

                  (iii)    a sale of all or substantially all of the Assets of
                           the Company.

         Upon the expiration of the Employment Term, Employee will return to the
Company all property of the Company, including, but not limited to, keys, credit
cards, financial reports, source codes, object codes, programs, flow charts,
formulae, customer and supplier information and all other materials relating to
the Business. The aforesaid obligations include all media containing such
information including any magnetic or optical media or other storage device.

Section 10 - Covenant Not to Compete.
------------------------------------

         (a)      The Employee covenants and agrees that during the Restricted
                  Period, the Employee will not, directly or indirectly, Compete
                  anywhere that the Company engages in Business; Employee
                  recognizing that a

                                       6
<PAGE>

                  substantial portion of the Company's business is outside North
                  America. Without limiting the generality of the foregoing
                  restrictive covenant, the Employee further covenants and
                  agrees that during the Restricted Period, he will not,
                  directly or indirectly (whether as owner, principal, employee,
                  partner, director, officer, member, lender, guarantor, surety,
                  indemnitor, or consultant to any person, firm, partnership,
                  corporation or other legal entity): (i) promote the business
                  of any person, firm, association or corporation or other
                  entity engaged in a business which Competes with the Business;
                  (ii) solicit, divert, take away or attempt to solicit, divert
                  or take away any of the Company's customers; (iii) cause or
                  attempt to cause any of the Company's customers to cease
                  transacting business with the Company; or (iv) induce or
                  attempt to induce any employee of the Company to terminate
                  such employment. Notwithstanding the foregoing, recognizing
                  that Employee and his Affiliates' other activities include
                  investments in private and public corporations and other
                  entities, nothing in this Agreement shall preclude Employee or
                  his Affiliates, directly or indirectly, from providing capital
                  to other businesses, including businesses that may Compete
                  with the Company or its subsidiaries; provided that Employee
                  may not (i) have more than a 10% equity interest, on a fully
                  diluted basis, in any entity that Competes with the Company or
                  its subsidiaries, (ii) nor serve as an officer, director or
                  advisor to such entity.

         (b) REASONABLENESS OF RESTRICTIONS. Employee acknowledges that: (1) his
experience and capabilities are such that the provisions of this Section 10 will
not prevent Employee from earning a livelihood or applying his professional
skills and knowledge; (ii) the terms and conditions contained in this Section 10
and in Section 11 hereof are reasonable and necessary for the protection of the
Business by the Company; and (iii) the nature of the employment arrangement
contemplated hereby is such that the Company may not be adequately compensated
with monetary damages for any violation by the Employee of any of the provisions
of this Section 10 or Section 11 hereof.

         Accordingly, the Employee agrees and consents that if Employee violates
any of the provisions contained in this Section 10 or Section 11 hereof, the
Company will be entitled to apply for an injunction, to be issued by any court
of competent jurisdiction, restraining the Employee from committing or
continuing any violation of this Section 10 or Section 11 hereof, and that any
such remedy sought or obtained by the Company will not be considered a waiver of
the rights of the Company to assert any other remedies it may have under this
Agreement, at law or, in equity.

                                       7
<PAGE>

         (c) SEVERABILITY. The Employee agrees that each of the covenants set
forth in this Section 10 is separate and distinct, independent of others, and
that the illegality or invalidity of any one or more of them or any part of one
or more of them will not render the others illegal or invalid, and that if the
invalidity or unenforceability is due to the unreasonableness of the time or
geographical area covered by said covenants and restrictions, said covenants and
restrictions will nevertheless be enforced to the maximum extent permitted by
law and effective for such period of time and for such area as may be determined
to be reasonable by a court of competent jurisdiction, and the Employee hereby
consents and agrees that such scope may be judicially modified, accordingly, in
any proceeding brought to enforce such covenants and restrictions.

         (d) INDEPENDENT SIGNIFICANCE. The restrictive covenants set forth in
this Section 10 and the covenants of confidentiality contained in Section 11
below on the part of the Employee are of the essence of this Agreement and will
be construed as independent of any other of the provisions of this Agreement
(other than the Company's monetary obligations to Employee under Sections 4 or
9), and the existence of any claim or cause of action of the Employee against
the Company (other than a claim under Section 4 or 9 hereof), whether predicated
on this Agreement or otherwise, will not constitute a defense to the enforcement
by the Company of any of said restrictive covenants.

Section 11 - Confidential Information.
--------------------------------------

         (a) NON-DISCLOSURE IN GENERAL. As a consequence of the Employee's
employment with the Company, the Employee has and will receive and deal with

be irreparably damaged if the Employee were to disclose (other than as permitted
in this Agreement) any of the Confidential Information that the Employee has

the Company, or will acquire or deal with as a result of his involvement with
the Company. The Employee acknowledges that all Confidential Information and
other information regarding the Company compiled or obtained by the Employee, or
furnished to the Employee in connection with his involvement with the Company is

this Agreement for any reason, the Employee will surrender to the Company all

                  (iii)    the Employee independently developed without the use
                           of any Confidential Information received from the
                           Company; or

Section 12 - Non-Waiver.
------------------------

         The failure of either party at any time or from time to time to require
performance of any of the other party's obligations under this Agreement will in
no matter affect such party's rights to enforce any provision of this Agreement

         shall designate an Issuing Lender for a Letter of Credit by delivering
         an Issuance Notice to a U.S. Lender. In the event that the Issuing
         Lender designated by the Domestic Borrower elects not to Issue such
         Letter of Credit, the Administrative Agent shall promptly so notify the
         Domestic Borrower, whereupon the Domestic Borrower may request any
         other U.S. Lender to Issue such Letter of Credit by delivering to such
         U.S. Lender a copy of the applicable Issuance Notice. Any U.S. Lender
         so requested to issue such Letter of Credit shall promptly notify the
         Domestic Borrower and the Administrative Agent whether or not, in its
         sole discretion, it has elected to Issue such Letter of Credit, and any
         such U.S. Lender which so elects to Issue such Letter of Credit shall
         be the Issuing Bank with respect thereto. If no U.S. Lender is
         designated by the Domestic Borrower or if the U.S. Lender or U.S.
         Lenders designated by the Domestic Borrower elect not to Issue the
         Letter of Credit (and the Domestic Borrower has not withdrawn the
         Issuance Notice), the Issuing Lender shall be Bank One."

Section 3.04 of the Credit Agreement is hereby amended by deleting it in its
entirety and substituting the following in lieu thereof:

                  and the Issuing Lender each shall have received, in accordance

                  documents and information as the applicable Issuing Lender may
                  reasonably require in connection with the Issuance of such
                  Letter of Credit.

                  (b) General Advance Conditions. On the date of Issuance of
                  each Letter of Credit, all conditions precedent described in
                  Section 3.02 shall be satisfied to the same extent as though
                  the Issuance of such Letter of Credit were the making of a
                  Borrowing and the date of Issuance of such Letter of Credit
                  were a date of the funding of such Borrowing."
