                               DAVOX CORPORATION

                     Non-Qualified Stock Option Agreement
                     ------------------------------------

                          for Non-Employee Directors
                          --------------------------

          Davox Corporation, a Massachusetts corporation (the "Company"), hereby
grants this ((Date)) to ((Name)) (the "Optionee"), an option to purchase a
maximum of ((Shares)) shares of its Common Stock, $.10 par value (the "Option
Shares"), at the price of ((Price)) per share, on the following terms and
conditions:

          1.       Grant Under 1988 Non-Employee Director Stock Option Plan. 
This option is granted pursuant to and is governed by the Company's 1988 Non-
Employee Director Stock Option Plan (the "Plan") and, unless the context
otherwise requires, terms used herein shall have the same meaning as in the
Plan. Determinations made in connection with this option pursuant to the Plan
shall be governed by the Plan as it exists on this date. In the event of any
conflict between this Agreement and the provisions of the Plan, the Plan shall
govern.

          2.       Grant as Non-Qualified Option: Other Options. This option is
intended to be a non-qualified option (rather than an incentive stock option),
and the Board of Directors intends to take appropriate action, if necessary, to
achieve this result. This option is in addition to any other options heretofore
or hereafter granted to the Optionee by the Company, but a duplicate original of
this instrument shall not effect the grant of another option.

          3.       Extent of Option if Service as a Director Continues.

                   (a) If the Optionee has continuously served as a member of
the Board of Directors through the following dates, the Optionee may exercise
this option for the number of shares set opposite the applicable date:
<TABLE> 
<CAPTION> 
            Cumulative Number of Shares
          for which Option is Exercisable               Date of Vesting 
          -------------------------------               --------------- 
          <S>                                   <C> 
          1/4 of total Option Shares            One year after date of option grant 
          1/2 of total Option Shares            Two years after date of option grant 
          3/4 of total Option Shares            Three years after date of option grant 
          100% of total Option Shares           Four years after date of option grant
</TABLE> 

The foregoing rights are cumulative.

                   (b) While the Optionee continues to serve as a member of the
Board of Directors, the rights under Article 3(a) hereof, as applicable, may be
exercised up to and including the date which is five (5) years from the date
this option is granted. All of the foregoing rights are subject to Article 4
hereof, as appropriate, if the Optionee ceases to serve as
<PAGE>
 
                                      -2-


a member of the Board of Directors or dies or becomes disabled while serving as
a member of the Board of Directors.

          4.       Termination of Option Rights.

                   (a) In the event the Optionee ceases to be a member of the
Board of Directors of the Company for any reason other than death or permanent
disability, the then unexercised portion of this Option shall, to the extent not
then vested, immediately terminate and become void; the portion of this Option
then vested but which has not been exercised at the time the Optionee so ceases
to be a member of the Board of Directors may be exercised, to the extent then
vested, by the Optionee within ten (10) days of the date of the Optionee ceases
to be a member of the Board of Directors of the Company, but in no event later
than the expiration date of the option.

                   (b) In the event that the Optionee ceases to be a member of
the Board of Directors of the Company by reason of his permanent disability or
death, any option granted to the Optionee may be exercised, to the extent of the
number of shares with respect to which the Optionee could have exercised it on
the date of such disability or death (by the Optionee's personal representative,
heir or legatee, in the event of death) during the period ending one hundred
eighty (180) days after the date the Optionee so ceases to be a member of the
Board of Directors, but in no event later than the expiration date of the
option.

          5.       Partial Exercise. Exercise of this option up to the extent
above stated may be made in part at any time and from time to time within the
above limits and within any limits established by the Plan, except that this
option may not be exercised for a fraction of a share unless such exercise is
with respect to the final installment of stock subject to this option and a
fractional share (or cash in lieu thereof) must be issued to permit the Optionee
to exercise completely such final installment. Any fractional share with respect
to which an installment of this Option cannot be exercised because of the
limitation contained in the preceding sentence shall remain subject to this
Option and shall be available for later purchase by the Optionee in accordance
with the terms hereof.

          6.       Payment of Price. The option price is payable in United
States dollars and may be paid: (a) in cash or by check, or any combination of
the foregoing, equal in amount to the option price; or (b) in the discretion of
the Board of Directors, in cash, by check, by delivery of shares of the
Company's Common Stock having a fair market value (as determined by the Board of
Directors) equal as of the date of exercise to the option price, or by any
combination of the foregoing, equal in amount to the option price.

          If the Optionee delivers Common Stock held by the Optionee (the "Old
Stock") to the Company in full or partial payment of the option price, and the
Old Stock so delivered is subject to restrictions or limitations imposed by
agreement between the Optionee and the Company, the Common Stock received by the
Optionee on the exercise of this option shall be subject to all restrictions and
limitations applicable to the Old Stock to the extent that the Optionee paid for
<PAGE>
 
                                      -3-


such Common Stock by delivery of Old Stock, in addition to any restrictions or
limitations imposed by this Agreement.

          7.    Agreement to Purchase for Investment. By acceptance of this
option, the Optionee agrees that a purchase of shares under this option will not
be made with a view to their distribution, as that term is used in the
Securities Act of 1933, as amended, unless in the opinion of counsel to the
Company such distribution is in compliance with or exempt from the registration
and prospectus requirements of that Act, and the Optionee agrees to sign a
certificate to such effect at the time of exercising this option and agrees that
the certificate for the shares so purchased may be inscribed with a legend to
ensure compliance with that Act.

          8.    Method of Exercising Option. Subject to the terms and conditions
of this Agreement, this option may be exercised by written notice to the
Company, addressed to the Treasurer, at the principal executive office of the
Company. Such notice shall state the election to exercise this option and the
number of shares in respect of which it is being exercised and shall be signed
by the person or persons so exercising this option. Such notice shall be
accompanied by payment of the full purchase price of such shares, and the
Company or its transfer agent shall deliver a certificate or certificates
representing such shares as soon as practicable after the notice shall be
received. The certificate or certificates for the shares as to which this option
shall have been so exercised shall be registered in the name of the person or
persons so exercising this option (or, if this option shall be exercised by the
Optionee and if the Optionee shall so request in the notice exercising this
option, shall be registered in the name of the Optionee and another person
jointly, with right of survivorship) and shall be delivered as provided above to
or upon the written order of the person or persons exercising this option. In
the event this option shall be exercised, pursuant to Article 4 hereof, by any
person or persons other than the Optionee, such notice shall be accompanied by
appropriate proof of the right of such person or persons to exercise this
option. All shares that shall be purchased upon the exercise of this option as
provided herein shall be fully paid and non-assessable.

          9.    Option Not Transferable. This option is not transferable or
assignable except by will or by the laws of descent and distribution. During the
Optionee's lifetime only the Optionee can exercise this option.

          10.   No Obligation to Exercise Option. The grant and acceptance of
this option imposes no obligation on the Optionee to exercise it.

          11.   No Rights as Stockholder until Exercise. The Optionee shall have
no rights as a stockholder with respect to any of the Option Shares until a
stock certificate therefor has been issued to the Optionee and is fully paid
for. Except as is expressly provided in the Plan with respect to certain changes
in the capitalization of the Company, no adjustment shall be made for dividends
or similar rights for which the record date is prior to the date such stock
certificate is issued.

          12.   Capital Changes and Business Successions. It is the purpose of
this option to encourage the Optionee to work for the best interests of the
Company and its stockholders.

                                      -4-


Since, for example, that might require the issuance of a stock dividend or a
merger with another corporation, the purpose of this option would not be served
if such a stock dividend, merger or similar occurrence would cause the
Optionee's rights hereunder to be diluted or terminated and thus be contrary to
the Optionee's interest. The Plan contains extensive provisions designed to
preserve options at full value in a number of contingencies. Therefore,
provisions in the Plan for adjustment with respect to stock subject to options
and the related provisions with respect to successors to the business of the
Company are hereby made applicable hereunder and are incorporated herein by
reference.

          13.   Withholding Taxes. The Optionee hereby agrees that the Company
may withhold from the Optionee's wages or other remuneration the appropriate
amount of federal, state and local taxes attributable to the Optionee's exercise
of any installment of this Option. At the Company's discretion, the amount
required to be withheld may be withheld in cash from such wages or other
remuneration, or in kind from the Common Stock otherwise deliverable to the
Optionee on exercise of this option. The Optionee further agrees that, if the
Company does not withhold an amount from the Optionee's wages or other
remuneration sufficient to satisfy the Company's withholding obligation, the
Optionee will reimburse the Company on demand, in cash, for the amount
underwithheld.

          14.   Governing Law. This Agreement shall be governed by and
interpreted in accordance with the internal laws of the Commonwealth of
Massachusetts.
