(Supercedes all previous offers)



Mr. Thomas Ryan
650 Castro Street
Suite 300
Mountain View, CA  94041

Dear Tom:

On behalf of Manugistics, Inc., as well as its parent company, Manugistics
Group, Inc. and the Board of Directors of both, we are pleased to confirm our
email offer for the position of Senior Vice President, North America Sales,
reporting to Richard F. Bergmann, Executive Vice President, Global Sales &
Services. This offer of employment is contingent upon Manugistics' completion of
the acquisition of Talus Solutions, Inc. ("Talus"), expected to "close" (the
"Closing") in the fourth quarter of Manugistics' fiscal year, and, except as
noted below, will supercede the terms of any compensation agreements or
arrangements which you may have with Talus. This position is exempt.

In this position your monthly salary will be $18,750. This position has regular
performance reviews. Performance reviews at Manugistics are scheduled for March
1 of each year. Your first performance review will be March 1, 2002. We will
recommend to the Board of Directors that the Board grant you an option, on the
day after Closing, to purchase 72,000 (calculated on a pre-split basis) shares
of common stock under an applicable Stock Option Plan. At the time of grant, the
number of shares in this option will be doubled to give you the benefit of the
upcoming stock split. Our Stock Plan Administrator will provide you with written
confirmation of stock options awarded. These options shall vest over a four (4)
year period and we will recommend to the Board of Directors that such options
vest in equal monthly increments over such four (4) year period (options will be
valued at a price equal to the Fair Market Value of Manugistics stock on the
date of grant).

You will also have the opportunity to receive an annual incentive bonus, in
accordance with Manugistics' Incentive Plan, of up to $225,000 to be paid in
four (4) quarterly payouts of up to $56,250, based on Manugistics' financial
performance of sales growth, earnings and specific management objectives and
initiatives to be determined and approved by Mr. Bergmann. Your FY02 Incentive
Plan will commence at the beginning of Manugistics' 2002 fiscal year which
begins March 1, 2001. You will also receive (on the date that it was scheduled
to have been paid) any bonus compensation to which you may be entitled for
calendar year 2000 under your existing offer letter with Talus.

Thereafter, you will not be entitled to any further bonus compensation under the
terms of your existing offer letter with Talus. You will, however, remain
subject to the requirement in your Talus offer letter that you repay the full
amount of your guaranteed bonus (as referenced in your Talus offer letter)
within 30 days of your termination date if you terminate your employment within
one (1) year of your Talus start date, and by signing this offer letter you
agree that this repayment may be offset against any monies owed to you.

Furthermore, as consideration for our agreement to accelerate vesting of your
Talus options as described below, in the event that you voluntarily leave your
employment within one (1) year of Closing, you agree that you:

a)      will repay within thirty days of termination of your employment all
        bonus and incentive payments made, to you by us, regardless of whether
        such bonus and incentive payments arise out of your Talus offer letter
        or this offer letter, and

b)      will forfeit all amounts accrued as bonus or incentive payments to be
        made, to you by us, regardless of whether such bonus and incentive
        payments arise out of your Talus offer letter or this offer letter

By signing this offer letter you agree that the repayment set forth in a) and b)
above, may be offset against any monies owed to you.

In the event that Manugistics has a change of control, which is defined as fifty
one percent (51%) of Manugistics' voting stock having a change in ownership: (a)
if your responsibilities are not affected, fifty percent (50%) of your
outstanding options set out above shall immediately vest; (b) if your
responsibilities are significantly diminished or you are constructively
terminated, i.e., your responsibilities no longer consist of those reasonably
associated with the position of Senior Vice President, North America Sales, one
hundred percent (100%) of the outstanding options set out above shall
immediately vest.

If the Company terminates your employment for reasons other than cause, you will
receive your base salary, corresponding management objectives bonus, and
benefits in accordance with the Company's payroll practices for the equivalent
of a six (6) month period commencing on your termination date ("severance
period"). The foregoing salary and benefits payments will cease if you secure
alternative employment during the severance period. In addition, if the Company
terminates your employment for reasons other than cause, the Company will
continue the monthly vesting of the options granted to you pursuant to this
letter for a period of six (6) months following your termination date.

Please note that the vesting, change of control and other terms described herein
are applicable only to the Manugistics option to acquire the shares specifically
set forth in this letter.

The terms and conditions of this letter shall have no effect on any existing
Talus options or shares of Talus stock you currently hold or any future option
grants to which you are (or may be) entitled under your existing offer letter
with Talus. These will all be converted to stock or options to acquire stock of
Manugistics using the Exchange Ratio set forth in the merger agreement between
Manugistics and Talus, except that any future option grants will not be made
unless and until all conditions described in your Talus offer letter are
satisfied. Options which have been granted prior to the date of merger will
otherwise have the same terms and conditions as they had before, except that
your option to acquire 375,000 shares of Talus common stock shall be modified so
that it shall vest as follows: 25% of the original 375,000 shares on the day
after Closing, an additional 25% of the original 375,000 shares on the first
anniversary of your original grant date from Talus, with the balance vesting in
thirty-six (36) equal monthly installments on the same day of each month as the
date of Closing, commencing in January 2001. We have discussed with you and you
understand that this change in vesting may cause all or a portion of this option
to fail to qualify for incentive stock option treatment under the Internal
Revenue Code. Any future option grants will be made under the terms of the
Manugistics' stock option plan under which they are granted and will be granted
on a post-split basis. By accepting this offer, you also agree that the merger
will not constitute a "change of control in ownership which effects your
employment status" within the meaning of your offer letter with Talus dated July
7, 2000.

This offer is subject to approval by the Compensation Committee of the Board of
Directors of Manugistics Group, Inc. Furthermore, all compensation and benefits
included as part of this offer will conform to the Company's standard policies,
practices and plans. In the event of any question with regard to the
compensation and benefits described in this letter, the Compensation Committee
of the Board of Directors will make the final determination with regard to any
interpretation relating to the elements of your compensation package.

You agree that the existence of this letter, as well as the terms and provisions
of this letter, shall remain confidential subject to Manugistics' obligation to
discharge a filing obligation to, or respond to an inquiry from, a government
agency or department or self-regulatory organization. If you disclose the
existence of this letter, or any of the terms or provisions of this letter, to a
third party, we will be entitled to treat such unauthorized disclosure as a
breach of this letter and will be relieved of all obligations under this letter.

In keeping with Manugistics policy, all offers are contingent upon your
execution of "Manugistics, Inc.'s Conditions of Employment."
