Re:  Offer of Employment

Dear Kevin:

        Digital Impact, Inc. (the "COMPANY") is pleased to offer you employment
on the terms set forth below (this "AGREEMENT").

        Title. You will have the title of Senior Vice President of Services and
you will report to William C. Park, in his capacity as Chief Executive Officer
of the Company. As a Company employee, you will be expected to abide by all of
the Company's policies and procedures, and acknowledge in writing that you have
received and read the employee handbook, which will be made available to you
following the date you commence employment with the Company (your "COMMENCEMENT
DATE").

        Duties. Your duties as Senior Vice President of Services will be to
manage the Company's Services department, overseeing all aspects of the quality
of service delivered to the Company's clients.

        Salary and Benefits. Your initial base salary will be two hundred
thousand dollars ($200,000) per year, less applicable payroll deductions and
withholdings. As an exempt employee, you will be paid on a salary, not hourly,
basis. Therefore, you will be "exempt" from overtime pay. You will be paid two
times per month in accordance with the Company's payroll practices for employees
generally. In addition, the Company will provide you with sick leave, ten days
of paid vacation time, and medical, dental, and other benefits coverage
consistent with Company policy. The Company reserves the right to modify
benefits available to employees from time to time, as it deems necessary.

        Signing Bonus. The Company will pay you a sixty-two thousand five
hundred dollars ($62,500) signing bonus (the "SIGNING BONUS") due upon your
Commencement Date, less applicable payroll deductions and withholdings. You will
be required to repay the entire Signing Bonus in the event you voluntarily
terminate your employment with the Company prior to the date that is six (6)
months following your Commencement Date.

<PAGE>
        Stock Options.

                Signing Grant. On or following your Commencement Date (but in
any event no later than thirty (30) days following your Commencement Date), in
compliance with all applicable regulatory requirements and subject to applicable
approvals, you will be eligible to receive a stock option to purchase two
hundred twenty-five thousand (225,000) shares of the Company's common stock (the
"SIGNING GRANT"). The exercise price of the Signing Grant will be the fair
market value of the Company's common stock on the date of grant. The Option will
vest in equal monthly installments over four (4) years.

               Performance Grant. On or following your Commencement Date (but in
any event no later than thirty (30) days following your Commencement Date), in
compliance with all applicable regulatory requirements and subject to applicable
approvals, you will be eligible to receive a stock option to purchase one
hundred twelve thousand five hundred (112,500) shares of the Company's common
stock (the "PERFORMANCE GRANT"). The exercise price of the Performance Grant
will be the fair market value of the Company's common stock on the date of
grant. The Performance Grant will vest over a one-year period in accordance with
the terms set forth on Schedule A.

        Indemnification. You shall be indemnified by the Company to the same
extent as other Company executives. In addition, the Company shall indemnify you
for personal liability you may incur arising from claims against you in
connection with your leaving your current employment and taking a position with
the Company. Both parties acknowledge that your decision to join the Company and
the Company's decision to offer you a position were made independent of the
Company's decision of whether to make a bid for the assets of Post
Communications, Inc. ("POST") in a currently pending bankruptcy proceeding.

        Severance. In the event that the Company does not acquire the assets of
Post, and within six (6) months following your Commencement Date the Company
terminates your employment other than for Cause (as defined below), you will be
entitled to receive a severance payment equal to two (2) months' salary, less
applicable payroll deductions and withholdings, subject to your execution of a
release in form and substance satisfactory to the Company.

For purposes of this Agreement, "CAUSE" shall mean any of the following: (i)
conviction of any felony or any crime involving dishonesty; (ii) participation
in a fraud or act of dishonesty against the Company; (iii) willful breach of the
Company's policies; (iv) intentional damage to the Company's property; (v)
material breach of this Agreement or your Proprietary Information and Inventions
Agreement; or (vi) conduct by you which in the good faith and reasonable
determination of the Board demonstrates unacceptable job performance or gross
unfitness to serve provided that you have had fair notice of such cause and do
not substantially cure or mitigate its consequences to the

                                       2
<PAGE>

reasonable satisfaction of the Company as determined by the Board within thirty
(30) days after the Company notifies you in writing of the cause.

        Change in Control Protection. The Company maintains a change in control
program for its senior executives. You will be a participant in this program on
the same terms and conditions offered to executives of the Company generally.

        Protection of Company Interests. As a Company employee, you will be
expected to sign and comply with the Company's standard Proprietary Information
and Inventions Agreement which, among other things, prohibits unauthorized use
or disclosure of Company proprietary information and which prohibits, without
the express written consent of a duly authorized officer of the Company,
engagement in any employment or business activity other than for the Company.

        At-Will Employment. Your employment with the Company is at-will. This
means that you may resign your employment at any time simply by notifying the
Company. Likewise, the Company may terminate your employment relationship at any
time and for any reason whatsoever, with or without cause or advanced notice,
simply by notifying you. This at-will employment relationship cannot be changed
except in a writing signed by a duly authorized officer of the Company.

        Miscellaneous. This Agreement, including the attachments, if any,
constitutes the complete, final and exclusive embodiment of the entire agreement
between you and the Company with respect to the terms and conditions of your
employment. This Agreement is entered into without reliance upon any promise,
warranty or representation, written or oral, other than those expressly
contained herein, and it supersedes any other such promises, warranties,
representations or agreements. It may not be amended or modified except by a
written instrument signed by you and a duly authorized officer of the Company.
If any provision of this Agreement is determined to be invalid or unenforceable,
in whole or in part, this determination will not affect any other provision of
this Agreement, which shall remain in full force and effect. This Agreement
shall be construed and interpreted in accordance with the laws of the State of
California, without reference to the choice of law provisions thereof.

        As required by law, this offer of employment is subject to satisfactory
proof of your right to work in the United States.

                                       3

(1)   In the event that the Company determines to take actions that are the
      primary result of the loss of all or substantially all of the business of
      a client on which these performance criteria are based (including, but not
      limited to, the possible transition of such clients from Post's platform
      to the Company's platform, if applicable), both parties shall in good
      faith review and, if justified, revise this performance criterion. The
      parties understand that the most important factor underlying the retention
      of clients is good service. Thus, whether a failure to provide good
      service is the primary result of the loss of a client shall be a
      significant factor in the determination of whether any revision is
      justified. If the Company does not acquire the assets of Post, the
      satisfaction of the performance goals in this table shall be calculated
      with reference only to Company clients.

(2)   Retention of all or substantially all of the business of at least the
      specified percentage of the Company's clients through the end of the
      applicable vesting period. Vesting, if any, will occur at the end of the
      applicable vesting period.

(3)   Measured and vested following the end of the applicable vesting periods
      following the Company's Finance Department's certification of recognized
      revenue. "Revenue Growth" is determined by comparing the actual recognized
      revenue for the applicable six-month period for all Company clients
      against two (2) times the actual revenue of the Company's (and Post's
      clients, if applicable) for the fiscal quarter ending December 31, 2001.
      The parties shall agree in good faith whether any particular client should
      be excluded from the revenue growth calculations based on such client
      leaving the Company or Post on account of factors beyond for reasons not
      involving client service.<PAGE>

RE:  SECOND AMENDMENT TO RETAINER AGREEMENT BETWEEN REGENT PACIFIC MANAGEMENT
     CORPORATION AND AUSPEX SYSTEMS, INC.

This Second Amendment to Retainer Agreement sets forth certain amendments to
the Retainer Agreement between Regent Pacific Management Corporation, a
California corporation ("Regent Pacific"), and Auspex Systems, Inc., a
California corporation, and its wholly-owned and controlled subsidiaries
(collectively, "Auspex") dated February 10, 2000, as amended October 17, 2000
(the "Original Retainer Agreement" and "First Amendment," respectively). Except
for the amendments expressly contained herein, the Original Retainer Agreement
and First Amendment shall remain in full force and effect.

1. The paragraph regarding "Fees" of the Original Retainer Agreement is
   hereby amended in its entirety as follows:

     "FEES: We have agreed to provide the work product included in this
     agreement for the period beginning February 14, 2000 through June 30,
     2003, including a non-cancelable period which extends through December 31,
     2002. The fees for these services shall be $75,000 per week payable in
     four (4) week increments, each to be paid in advance of each Regent
     Pacific standard four-week billing period. It is agreed and understood
     that the fees payable and the level of services provided will remain at
     their current levels. It is further agreed and understood that the
     payments of such cash fees are to be made immediately preceding the start
     of each four-week billing period, and that failure to pay such periodic
     payments when due shall constitute a breach of this agreement by Auspex.
     It is further understood that Regent Pacific's fees are to be paid in
     advance of the work to be performed, and that the initial payment is to be
     paid on or before the start of the engagement. It is further agreed that
     such cash payments are earned in full upon receipt by Regent Pacific, by
     virtue of our accepting this agreement and the responsibilities it entails,
     and are nonrefundable."

2.   The paragraph regarding "Term of agreement" of the Original Retainer
     Agreement is hereby amended in its entirety as follows:

          "TERM OF AGREEMENT: The full term of this agreement shall be from
          February 14, 2000 through June 30, 2003. The agreement will be
          non-cancelable through December 31, 2002, unless earlier terminated by
          either party in accordance with the terms of this paragraph. Regent
          Pacific hereby commits the availability of its resources to Auspex
          under this agreement for the full term of the engagement, through
          June 30, 2003. Auspex may discharge Regent Pacific at any time after
          the non-cancelable period provided that Auspex delivers a 60-day
          written notice of intent to cancel this agreement. Regent Pacific may
          withdraw from this assignment at any time with Auspex's consent or
          for good cause without Auspex's consent. Good cause includes Auspex's
          breach of this agreement (including Auspex's failure to pay any
          invoice within five working days of presentation), or any fact or
          circumstance that would render our continuing participation in the
          assignment unethical or unlawful."

3.   A new paragraph regarding "Stock Options" is hereby added to the Original
     Retainer Agreement. It reads in its entirety as follows:

          "STOCK OPTIONS: In addition to the cash fees payable to Regent Pacific
          under the terms of this agreement, it is agreed that Auspex will
          grant stock options to Gary J. Sbona and/or his designees from time
          to time, initially as an inducement for employment and subsequently
          as an incentive for agreeing to extend the term of this agreement.
          The initial stock option grant to Gary J. Sbona, dated February 14,
          2000, was for two million four hundred thousand (2,400,000) shares of
          Auspex common stock. As part of the First Amendment, Auspex granted
          an option to Gary J. Sbona on October 17, 2000 for an additional
          seven hundred fifty thousand (750,000) shares of Auspex common stock.
          As part of this amendment, Auspex agrees that it will grant an option
          for an additional seven hundred fifty thousand (750,000) shares of
          Auspex common stock to Gary J. Sbona, plus five additional options to
          five designees of Gary J. Sbona. These five options will be for the
          following number of shares: One designee to receive an option for
          four hundred thousand shares of Auspex common stock; one designee to
          receive an option for three hundred thousand shares; one designee to
          receive an option for two hundred fifty thousand shares; and two
          designees to receive options for one hundred thousand shares each.
          All six of these option grants are to be granted as of the date
          Auspex next grants options to its key employees, at the market
          closing price as of that date. The total number of shares for all six
          options amounts to one million nine hundred thousand (1,900,000)
          shares of Auspex common stock. The terms of these six options grants,
          and of any subsequent option grants, shall be substantially similar
          to the February 14, 2000 and October 17, 2000 option grants,
          including but no limited to: a) vesting to commence immediately after
          the grant date, b) vesting to be monthly over a

          period of one year, or the remaining term of the Agreement, whichever
          is less, and c) the same "Change of Control" and the same Termination
          Period provisions as in the February 14, 2000 and October 17, 2000
          option grants. Stock options in addition to those referenced in this
          amendment may be granted to Gary J. Sbona and/or his designees from
          time to time at the sole discretion of Auspex Board of Directors."
