[Employee Name]
[Employee Address]

Dear [Employee Name]:

          Hall, Kinion & Associates, Inc. (the "Company") is pleased to
[make/amend] the offer letter ("Offer Letter") [that you executed with the
Company] on _________ __, ____ on the following terms:

          1.   Accelerated Vesting.  Subject to Section 3 below, upon a Change
          --   -------------------
in Control (as defined in Section 5 below), to the extent that your options
covering shares of the Company's Common Stock do not otherwise provide for full
vesting acceleration, you shall be entitled to the accelerated vesting of stock
options, as described below.

          (a) All options to purchase shares of the Company's Common Stock held
by you at the time of the Change in Control shall immediately become exercisable
and vested in full, whether such options were granted before or after the date
of this letter agreement.

          (b) All shares of the Company's Common Stock held by you at the time
of the Change in Control shall immediately vest in full and the Company's right
to repurchase such shares shall lapse, whether such shares were issued before or
after the date of this letter agreement.

          To the extent provided in this Section 1, this letter agreement shall
be deemed to be an amendment of the exercisability and vesting provisions of all
stock option agreements, stock purchase agreements and similar instruments
executed by you and the Company that did not otherwise provide for full vesting
acceleration upon a Change in Control.

          2. Salary Continuation and Other Benefits.  In the event that the
          -- --------------------------------------
Company terminates your employment without your consent for any reason other
than Cause (as defined in Section 7 below), or you experience a Constructive
Discharge (as defined in Section 6 below) within 12 months following a Change in
Control, then the Company shall pay to you each of the following or you will be
entitled to receive the following, subject to the terms of Section 3 below:

          (a) Your most recent base salary (at the annual rate then in effect)
for 12 months following the termination of your employment, in accordance with
the Company's standard payroll procedures;

                                                                         Page 2


          (b) An amount equal to the annual bonus that was paid to you for the
most recent 12-month period preceding your termination;

          (c) Your Company car that is leased by the Company on your behalf,
without any additional payments from you;

          (d) [Forgiveness of any outstanding principal and accrued and unpaid
interest under the promissory note, dated _________ ____, between you and the
Company; ]and

          (e) Continued coverage at the Company's expense under all medical
plans in which you and your dependents have participated through date of
termination, provided you are eligible for and elect COBRA coverage, for a
period extending through the earlier of 12 months after your termination of
employment and the date that your (or, with respect to a dependent, such
dependent's) COBRA eligibility ceases.

          3. Pooling of Interests.  If the Company and the other party to the
          -- --------------------
transaction constituting a Change in Control agree that such transaction is to
be treated as a "pooling of interests" for financial reporting purposes, and if
such transaction in fact is so treated, then the accelerated vesting of stock
options and shares described in Section 1 and the cash payment and other
benefits described in Section 2 shall not occur to the extent that the Company's
independent public accountants and such other party's independent public
accountants separately determine in good faith that such cash payment, benefits
or acceleration would preclude the use of "pooling of interests" accounting.

          4. Release of Claims.  Any other provision of this letter agreement
          -- -----------------
notwithstanding, the vesting acceleration, salary continuation and other
benefits described in Sections 1 and 2 shall not apply unless you (a) have
executed a general release (in a form prescribed by the Company) of all known
and unknown claims that you may then have against the Company or persons
affiliated with the Company and (b) have agreed not to prosecute any legal
action or other proceeding based upon any of such claims.

          5. Definition of Change in Control.  For all purposes under this
          -- -------------------------------
letter agreement, "Change in Control" shall mean the occurrence of any of the
following events after the date of this letter agreement:

          (a) a merger or consolidation in which securities possessing more than
fifty percent (50%) of the total combined voting power of the Company's
outstanding securities are transferred to a person or persons different from the
persons holding those securities immediately prior to such transaction; or

          (b) the sale, transfer or other disposition of all or substantially
all of the Company's assets in complete liquidation or dissolution of the
Company.

A transaction shall not constitute a Change in Control if its sole purpose is to
change the state of the Company's incorporation or to create a holding company
that will be owned in substantially
<PAGE>

Rita Hazell                                                    OCTOBER 21, 1999
                                                                         Page 3

the same proportions by the persons who held the Company's securities
immediately before such transaction.

          6. Definition of Constructive Discharge.  For all purposes under this
          -- ------------------------------------
letter agreement, "Constructive Discharge" shall mean that following one of the
following events, you resign from the Company:

          (a) Your responsibilities are materially diminished, you are assigned
duties that are inconsistent with your position under the Offer Letter or your
title is changed without your consent; or

          (b)  Your most recent base salary is reduced.

          7. Definition of Cause.  For all purposes under this letter agreement,
          -- -------------------
"Cause" shall mean:

          (a) Your failure to perform your material duties which continues for
more than 30 days after receipt of a written warning from the Company specifying
the act or omission that constitutes Cause, other than a failure resulting from
your complete or partial incapacity due to physical or mental illness or
impairment;

          (b) Conviction of, or a plea of "guilty" or "no contest" to, a felony
under the laws of the United States or any state thereof; or

          (c) Gross misconduct or fraud.

The foregoing, however, shall not be
deemed an exclusive list of all acts or omissions that the Company (or a
subsidiary of the Company) may consider as grounds for your discharge.

          8. Golden Parachute Excise Tax.
          -- ---------------------------

          (a) Application of Limitation.  This Section 8 shall apply only if
          --- -------------------------
you, on an after-tax basis, would receive more value under this letter agreement
after the application of this Section 8 than before the application of this
Section 8. For this purpose, "after-tax basis" shall mean a calculation taking
into account all federal and state income and excise taxes imposed on you,
including (without limitation) the excise tax described in section 4999 of the
Internal Revenue Code of 1986, as amended (the "Code"). If this Section 8 is
applicable, it shall supersede any conflicting provision of this letter
agreement. The rules set forth in this Section 8 supersede all other agreements
between you and the Company with respect to whether the Company shall make a
payment or property transfer to, or for the benefit of, you that would subject
you to the excise tax described in section 4999 of the Code, and Section 8 of
this letter agreement shall be deemed to be an amendment of such agreements.

          (b) Basic Rule. Unless the Company and the Executive otherwise agree
           --- ----------
in writing, the determination of Executive's excise tax liability and the amount
required to be paid under this Section 8 shall be made in writing by the
independent public accountants of the Company. For purposes of making
calculations required by this Section 8, the accountants may
<PAGE>

Rita Hazell                                                    OCTOBER 21, 1999
                                                                         Page 4


make reasonable assumptions and approximations concerning applicable taxes and
may rely on reasonable, good faith interpretations concerning the application of
Sections 280G and 4999 of the Code. The Company and the Executive shall furnish
to the accountants such information and documents as the accountants may
reasonably request in order to make a determination under this Section 8. The
Company shall bear all costs and expenses of the accountants in connection with
any work performed pursuant to the provisions of this Section 8.

          (c) Gross-Up.  In the event that the benefits provided for in this
          --- --------
Agreement or otherwise payable to Executive constitute "parachute payments"
within the meaning of Section 280G of the Internal Revenue Code of 1986, as
amended (the "Code") and will be subject to the excise tax imposed by Section
4999 of the Code, then Executive shall receive (i) a payment from the Company
sufficient to pay such excise tax, and (ii) an additional payment from the
Company sufficient to pay the excise tax and federal and state income taxes
arising from the payments made by the Company to Executive pursuant to this
Section 8.

          (d) Uncertainty of the calculation. As a result of uncertainty in the
          --- ------------------------------
application of section 4999 of the Code at the time of an initial determination
by the Auditors hereunder, it is possible that a payment will have been made by
the Company that should not have been made (an "Overpayment") or that an
additional payment that will not have been made by the Company could have been
made (an "Underpayment"). In the event that the Auditors, based upon the
assertion of a deficiency by the Internal Revenue Service against you that the
Auditors believe has a high probability of success, determine that an
Underpayment has occurred, such Underpayment shall promptly be paid or
transferred by the Company to, or for the benefit of, you, together with
interest at the applicable federal rate specified in section 7872(f)(2) of the
Code. In the event that the Auditors determine that an Overpayment has been
made, such Overpayment shall be treated for all purposes as a loan to you that
you shall repay to the Company, together with interest at the applicable federal
rate specified in section 7872(f)(2) of the Code; provided, however, that no
amount shall be payable by you to the Company if and to the extent that such
payment would not reduce the amount that is subject to an excise tax under
section 4999 of the Code. The Executive and the Company shall each reasonably
cooperate with the other in connection with any administrative or judicial
proceedings concerning the existence or amount of liability for Excise Tax with
respect to the "parachute payments".

          9. Successors.
          -- ----------

          (a) Company's Successors.  The Company shall require any successor
          ---  --------------------
(whether direct or indirect and whether by purchase, lease, merger,
consolidation, liquidation or otherwise) to all or substantially all of the
Company's business and/or assets, by an agreement in substance and form
satisfactory to you, to assume this letter agreement and to agree expressly to
perform this letter agreement in the same manner and to the same extent as the
Company would be required to perform it in the absence of a succession. For all
purposes under this letter agreement, the term "Company" shall include any
successor to the Company's business and/or assets which executes and delivers
the assumption agreement described in this Subsection (a) or which becomes bound
by this letter agreement by operation of law.

mail, return receipt requested and postage prepaid. In your case, mailed notices
shall be addressed to you at the home address which you most recently
communicated to the Company in writing. In the case of the Company, mailed
notices shall be addressed to its corporate headquarters, and all notices shall
be directed to the attention of its Secretary.

          (b) Waiver.  No provision of this letter agreement shall be modified,
          --- ------
waived or discharged unless the modification, waiver or discharge is agreed to
in writing and signed by you and by an authorized officer of the Company (other
than yourself). No waiver by either party of any breach of, or of compliance
with, any condition or provision of this letter agreement by the other party
shall be considered a waiver of any other condition or provision or of the same
condition or provision at another time.

          (c) Severability.  The invalidity or unenforceability of any
          --- ------------
provision or provisions of this letter agreement shall not affect the validity
or enforceability of any other provision hereof, which shall remain in full
force and effect.

          (d) No Retention Rights.  Nothing in this letter agreement shall
          --- -------------------
confer upon you any right to continue in service for any period of specific
duration or interfere with or otherwise restrict in any way your rights or the
rights of the Company or any subsidiary of the Company, which rights are hereby
expressly reserved by each, to terminate your service at any time and for any
reason, with or without Cause.

          (e) Choice of Law.  The validity, interpretation, construction and
          --- -------------

of California (other than their choice-of-law provisions).

          (f) Entire Agreement.  This letter and the Offer Letter contain all
          --- ----------------
of the terms of your employment with the Company and supersede any prior
understandings or agreements, whether oral or written, between you and the

          --- -----------------
letter agreement are subject to reduction to reflect applicable withholding and
payroll taxes.
