Exhibit (a)(4)


                                 [CLARUS LOGO]

April 9, 2001


Dear Employee Option Holder:

     Clarus recognizes that, as a result of today's difficult market conditions,
many of the stock options that have been granted to you under the Amended and
Restated Stock Incentive Plan of Clarus Corporation (the "Incentive Plan"), the
Stock Incentive Plan of Software Architects International, Limited (the "SAI
Plan") or the SQL 1992 Stock Option Plan (the "SQL Plan" and, together with the
Incentive Plan and the SAI Plan, the "Plans"), may not currently be providing
the performance incentives that were intended. We have considered a number of
ways to provide you with the benefit of options that over time may have a
greater potential to increase in value.

     As a result, I am happy to announce that Clarus is offering you the
opportunity to tender for exchange your currently outstanding options (vested
and unvested) under the Plans granted on or after November 1, 1999 (the
"Offer"). You may tender all or any portion of these options to Clarus in
exchange for new options as long as any partial tender includes at least 200
shares of common stock and is made only in increments of 100 shares of common
stock. In addition, if you tender any option grants for exchange, you must also
tender for exchange all option grants that you received during the six months
immediately prior to the date we accept tendered options for exchange which have
an exercise price which is lower than the exercise price of any other options
being tendered. Of course, you have the right to choose not to tender any of
your options.

     In addition, in order to give our employees the most flexibility, we will
be providing you with another opportunity to tender options beginning on or
around July 8. The terms and conditions of the exchange will generally be the
same as the terms and conditions of this offer. If you chose to tender options
in this offer, you will not be able to also tender options in July. Therefore,
you must decide whether to participate in this opportunity to tender options or
wait until July to tender options. Of course, you may choose not to tender
options either now or in July.

     The number of shares of Clarus' common stock that will be subject to the
new options will be equal to the number of shares currently subject to the
options that you tender and we accept for exchange, as adjusted for any stock
splits, stock dividends and similar events. We will grant the new options on the
first business day which is at least six months and one day following the date
we accept and cancel the tendered options. We expect to grant the new options to
you on or about November 9, 2001. Similarly, for options tendered in July, new
options are expected to be granted on or about January 10, 2002. Unfortunately,
we are not able to simply reprice your current options, offer an immediate grant
date, or carry forward current market prices to the grant date because doing so
would mandate additional and unfavorable compensation expenses under our
accounting and financial reporting requirements.

     Please note that this Offer is only to current employees of Clarus and its
subsidiaries and you must continue to be an employee of Clarus or one of our
subsidiaries from the date you tender your options for exchange through the date
the new options are scheduled to be granted in order to receive new options. If
you do not remain an employee of Clarus or any of our subsidiaries for any
reason during such period, you will not receive any new options or any other
consideration for the options tendered by you and cancelled.

     The terms and conditions of new options will be substantially the same as
the terms and conditions of your current options, except as specified in the
Offer, and will include the following terms:

     .    the per share exercise price of any new options granted to you will
          equal the fair market value of Clarus' common stock on the date we
          grant the new options, as determined by the last reported sale price
          of our common stock on the Nasdaq National Market on the date we grant
          the new options; and

                                                                          Page 1


     .    regardless of whether and to what extent the options that you tender
          for exchange have vested, any new options granted to you will vest in
          thirty-six equal monthly installments over the next three years.

     There is no way to predict what the price of our common stock will be
during the next six months or thereafter. It is possible that the market price
of our common stock on the date of grant of any new options issued to you will
be higher than the current exercise price of your options. It is also possible
that you will no longer be employed with Clarus or any of our subsidiaries at
the anticipated time of such new option grant. For these reasons, you should
make a decision to tender only after careful, considered thought.

     The board of directors makes no recommendation as to whether you should
tender or refrain from tendering your options in the Offer. You must make your
own decision whether to tender your options

     This offer is being made under the terms and subject to the conditions of
an offer to exchange and a related letter of transmittal which are enclosed with
this letter. You should carefully read the entire Offer to Exchange and Letter
of Transmittal before you decide whether to tender all or any portion of your
options. A tender of options involves risks which are discussed in the Offer to
Exchange.

     To tender options, you will be required to properly complete and return to
us the Letter of Transmittal and any other documents specified in that letter by
the expiration date of the Company's Offer. You must deliver a properly executed
paper copy or facsimile copy of the documents. E-mail delivery will not be
accepted.

     If you have any questions about the offer, please contact Pam Ellis, at
telephone: (770) 291-5394, facsimile: (770) 291-4775 or e-mail:
ellisp@claruscorp.com. We thank you for your continued efforts on behalf of
Clarus Corporation.

                              Sincerely,

                                     /s/ Stephen P. Jeffery
