Re:
Retention Bonus Letter Agreement

Dear
Wynn:

This
Retention Bonus Letter Agreement ("Agreement") will set forth the mutual understanding between you and TenFold Corporation (the "Company") regarding your agreement to continue your employment
with the Company.

You
are currently employed by the Company as its Vice President of Finance. You have reported that another employer has presented you with an employment opportunity. The Company has agreed that it is
in its best interest for you to remain in your current position with the Company at least through and including April 30, 2002.

Therefore,
for valuable consideration, the sufficiency of which is hereby acknowledged, you and the Company agree as follows:

Subject
to your execution of this Agreement, the Company will pay you a one-time, lump sum payment in the amount of one hundred thousand dollars ($100,000.00) (the "Retention Bonus"),
reduced by applicable withholdings, which sum shall be paid on or before December 31, 2001.

You
agree that you will immediately repay to the Company the Retention Bonus (less actual withholdings) in the event that 1) you voluntarily terminate your employment with the Company for any
reason and at any time prior to May 1, 2002, or 2) your employment is terminated for cause by the Company at any time prior to May 1, 2002, or 3) you fail to give the
Company one month's prior written notice before terminating your employment with the Company; provided, however, that you are not required to give such notice if the Company fails to meet your
scheduled payroll payments during any payroll period subsequent to the date of this agreement. (For avoidance of doubt, and notwithstanding anything in this Agreement to the contrary, you may give one
month's notice on or after April 1, 2002 without violating this Agreement. Also, upon your request, the Company may, in its sole discretion, waive this notice requirement.)

For
purposes of this Agreement, "termination for cause" means termination of your employment by the Company following the discovery of one or more of the following events, which events occurred after
the date of this Agreement and before May 1, 2002: (For avoidance of doubt, unless you have been previously notified otherwise, your performance during the past year represents acceptable
conduct in the completion of your duties.)

Notwithstanding
anything in this Agreement to the contrary, the Company agrees that you will have no obligation to repay the Retention Bonus following the discovery of one or more of the following
events, provided such events were caused by the Company and occurred after the date of this Agreement and before May 1, 2002:



You
will report to the Company's Chief Financial Officer. You will at all times, and to the best of your ability and experience, loyally and conscientiously perform all of the duties and obligations
required of you pursuant to the terms hereof or as directed by the Company's Chief Financial Officer. During the term of your employment relationship with the Company, you further agree that you will
not work for any other employer and will therefore devote all of your professional time, attention and effort to the business of the Company, and will use your reasonable best efforts to promote the
interests of the Company. For a period of six (6) months following the termination of your employment relationship

with the Company, you will not make derogatory or disparaging public remarks about the Company or any of its directors or officers that materially damages the Company or any of its directors or
officers.

The
Company agrees that after April 30, 2002, the Company must waive the non-solicitation provisions (and any other provisions that restrict third parties from hiring or soliciting
a TenFold employee, but not any provision with respect to holding information confidential) in its contracts with third parties who desire to employ you; provided, however, that the Company may
withhold such waiver if the Company can demonstrate that your being employed by the third party (rather than your leaving the Company) will have a material adverse effect on the Company's business.

You
expressly acknowledge that your employment is and shall continue to be at-will, as defined under applicable law. If your employment terminates for any reason, you shall not be entitled
to any payments (except through the effective date of the termination), benefits, damages, award or compensation other than as provided in this Agreement or as required by applicable law. In the event
your employment is terminated prior to May 1, 2002, the Company will pay unused vacation and holiday time at a rate equal to your annual base salary at the time of termination, but in no event
less than a rate of $100,000 per annum.

You
hereby represent that you are not a party to any agreement or contract with any other employer and that you will not, during the term of this Agreement, enter into any oral or written agreement in
conflict with any of the provisions of this Agreement. However, you may enter into an agreement for
employment after March 31, 2002, provided that such employment does not commence until after April 30, 2002.

You
also agree that after you sign this Agreement, you will hold strictly confidential the terms and conditions of this Agreement, except for disclosure to your legal and financial advisors, your
spouse and immediate family members, and the company that has presented you with another employment opportunity, each of whom shall be instructed by you to maintain the terms of this Agreement in
strict confidence.

In
addition, and in consideration for the Retention Bonus offered to you in this Agreement, you, for yourself and all persons claiming by, through or under you, hereby absolutely, irrevocably and
unconditionally release the Company and each of its affiliates, employees, officers, directors, shareholders, and agents (collectively "TenFold") from any and all claims against TenFold whatsoever
which you had, have, or may have with respect to any period prior to the date of this Agreement, directly or indirectly arising from or relating to your employment relationship with TenFold,
including, but not limited to, any claim relating to any and all liabilities, debts, demands, contracts, promises, agreements, claims, causes of action, injuries, costs, attorneys' fees, salary,
compensation, benefits (not including unused vacation or holiday time) and/or damages or any kind or character arising under or from any state or federal statute, local ordinance or common law.

Likewise,
in consideration for your staying with the Company at least through and including April 30, 2002, the Company and any entities claiming by, through or under the Company, hereby
absolutely, irrevocably and unconditionally release you from any and all claims whatsoever which the Company had, has, or may have with respect to any period prior to the date of this Agreement,
directly or indirectly arising from or relating to TenFold's employment relationship with you, including, but not limited to, any claim relating to any and all liabilities, debts, demands, contracts,
promises, agreements, claims, causes of action, injuries, costs, attorneys' fees, salary, compensation, benefits and/or damages or any kind or character arising under or from any state or federal
statute, local ordinance or common law.

This
Agreement and the Employee Proprietary Information and Invention Assignment Agreement set forth the entire agreement of the Company and you with respect to the subject matter hereof and supersede
and replace all prior negotiations, agreements, or representations, whether written or oral.

fees from the non-prevailing party.

Finally,
you acknowledge that you (1) have consulted with an attorney regarding this Agreement before agreeing to and signing it, (2) have read and fully understand the language and
