                 KEY VICE PRESIDENT CHANGE IN CONTROL AGREEMENT


         THIS AGREEMENT dated as of November 30, 1998 is made by and between
PictureTel Corporation, a Delaware Corporation, (the "Company") and Richard S.
Haak, Jr., 3 Peach Tree Path, Andover, MA 01810 ("Executive").

         WHEREAS the Company considers it essential to the best interests of the
Company, its shareholders, and its employees generally to foster the continuous
employment of key management personnel; and

         WHEREAS the Board of Directors of the Company (the "Board") recognizes
that, as is the case with many publicly held corporations, the possibility of a
Change in Control (as defined in the last Section hereof) exists and that such
possibility, and the uncertainty and questions which it may raise among the
Company's management, may result in the departure or distraction of management
personnel to the detriment of the Company and its shareholders; and

         WHEREAS the Board has determined that appropriate steps should be taken
to reinforce and encourage the continued attention and dedication of members of
the Company's management, including the Executive, to their assigned duties
without distraction in the face of potentially disrupting circumstances arising
from the possibility of a Change in Control;

         NOW THEREFORE, in consideration of the premises and the mutual
covenants herein contained and other good and valuable consideration, the
Company and the Executive hereby agree as follows:

         1.0      DEFINED TERMS. The definition of capitalized terms used in
this Agreement is provided in the last Section hereof.

         2.0      TERM OF AGREEMENT. This Agreement shall commence on the date
hereof and shall continue in effect through November 30, 2000; provided,
however, that commencing on December 1, 1998 and each December 1st thereafter,
the term of this Agreement shall automatically be extended for one additional
year unless, not later than September 30th preceding that December 1st, the
Company or the Executive shall have given notice not to extend this Agreement or
a Change in Control shall have occurred prior to such September 30th; provided,
however, if a Change in Control shall have occurred during the term of this
Agreement, this Agreement shall continue in effect for a period of not less than
twenty-four (24) months beyond the date on which such Change in Control
occurred.

         3.0      COMPANY'S COVENANTS SUMMARIZED. In order to induce the
Executive to remain in the employ of the Company and in consideration of the
Executive's covenants set forth in Section 4.0 hereof, the Company agrees, under
the conditions described herein, to pay the Executive the "Severance Payments"
described in Section 6.1 hereof and the other payments and benefits described
herein in the event the Executive's employment with the Company is terminated
following a Change in Control and during the term of this Agreement. No amount
or benefit shall be payable under this Agreement unless there shall have been
(or, under the terms hereof, there shall be deemed to have been) a termination
of the Executive's employment with the Company following a Change in Control.
This Agreement shall not be construed as creating an express or implied contract
of employment prior to the date of a Change in Control and the Executive shall
not have any right to be retained in the employ of the Company.

         4.0      THE EXECUTIVE'S COVENANTS. The Executive agrees that, subject
to the terms and conditions of this Agreement, in the event of a Potential
Change in Control during the term of this Agreement, the Executive will remain
in the employ of the Company until the earliest of (A) a date which is six (6)
months from the date of such Potential Change of Control, (B) the date of a



<PAGE>   2


Change in Control, (C) the date of termination by reason of death or Disability,
or (D) the termination by the Company of the Executive's employment for any
reason.

         5.0      COMPENSATION OTHER THAN SEVERANCE PAYMENTS.

         5.1      Following a Change in Control during the term of this
Agreement, during any period that the Executive fails to perform the Executive's
full-time duties with the Company as a result of incapacity due to physical or
mental illness, the Company shall pay the Executive's full salary to the
Executive at the rate in effect at the commencement of any such period, together
with all compensation and benefits payable to the Executive under the terms of
any compensation or benefit plan, program or arrangement maintained by the
Company during such period, until the Executive's employment is terminated by
the Company for Disability.

         5.2      If the Executive's employment shall be terminated for any
reason following a Change in Control during the term of this Agreement, the
Company shall pay the Executive's full salary to the Executive through the Date
of Termination at the rate in effect at the time the Notice of Termination is
given, together with all compensation and benefits payable to the Executive
through the Date of Termination under the terms of any compensation or benefit
plan, program or arrangement maintained by the Company prior to the Date of
Termination.

         5.3      If the Executive's employment shall be terminated for any
reason following a Change in Control during the term of this Agreement, the
Company shall pay the Executive's normal post-termination compensation and
benefits to the Executive as such payments become due. Such post-termination
compensation and benefits shall be determined under, and paid in accordance
with, the Company's retirement, insurance and other compensation or benefit
plans, programs and arrangements; provided however, that the Severance Payments
under Section 6.0 of this Agreement shall be the only severance paid following a
Change in Control during the term of this Agreement.

         6.0      SEVERANCE PAYMENTS.

         6.1      Subject to Section 6.2 hereof, the Company shall pay the
Executive the payments described in this Section 6.1 ("Severance Payments") upon
the termination of the Executive's employment following a Change in Control
during the term of this Agreement, in addition to the payments and benefits
described in Section 5.0 hereof, unless such termination is (A) by the Company
for Cause, or (B) by reason of Death or Disability. The Executive's employment
shall be deemed to have been terminated following a Change in Control by the
Company without Cause if the Executive's employment is terminated prior to a
Change in Control without Cause at the direction (or action which constitutes a
direction) of a Person who has entered into an agreement with the Company the
consummation of which will constitute a Change in Control.

                  (i)      Subsequent to the Date of Termination, the Company
                  shall make cash severance payments to the Executive over a
                  twelve (12) month period in substantially equal bi-weekly
                  installments, in an amount equal to one (1) times the sum of
                  (a) the higher of the Executive's annual base salary in effect
                  immediately prior to the occurrence of the event or
                  circumstance upon which the Notice of Termination is based or
                  in effect immediately prior to the Change in Control, and (b)
                  the higher of the highest annual bonus paid to the Executive
                  in the three years preceding the year in which the Date of
                  Termination occurs or paid in the three years preceding the
                  year in which the Change in Control occurs.

                  (ii)     For a twelve (12) month period after the Date of
                  Termination, the Company shall arrange to provide the
                  Executive with medical and dental insurance benefits
                  substantially similar to those which the Executive is
                  receiving on the same premium cost share basis immediately
                  prior to the Notice of Termination. Benefits otherwise
                  receivable by the Executive pursuant to this Section 6.1(ii)
                  shall be reduced to the extent comparable benefits are
                  actually received by or made available to the 


<PAGE>   3

                  Executive without cost during the twelve (12) month period
                  following the Executive's termination of employment (and any
                  such benefits actually received by the Executive shall be
                  reported to the Company by the Executive). If the benefits
                  provided to the Executive under this Section 6.1(ii) shall
                  result in a decrease, pursuant to Section 6.2, in the Change
                  in Control Payments and these Section 6.1(ii) benefits are
                  thereafter reduced pursuant to the immediately preceding
                  sentence because of the receipt of comparable benefits, the
                  Company shall, at the time of such reduction, pay to the
                  Executive the lesser of (a) the amount of the decrease made in
                  the Severance Payments pursuant to Section 6.2, or (b) the
                  maximum amount which can be paid to the Executive without
                  being, or causing any other payment to be, nondeductible by
                  reason of section 28OG of the Code.

         6.2      Notwithstanding any other provisions of this Agreement, in the
event that any payment or benefit received or to be received by the Executive in
connection with a Change in Control or the termination of the Executive' s
employment (whether or not received pursuant to the terms of this Agreement)
(all such payments and benefits, including but not limited to the Severance
Payments, being hereinafter called the "Total Payments") would be subject in
whole or in part to the Excise Tax, then the Severance Payments shall be reduced
to the extent, but only to the extent, necessary so that no portion of the Total
Payments is subject to the Excise Tax; provided, that no such reduction shall be
effected unless the net amount of the Total Payments after such reduction in the
Severance Payments and after deduction of the net amount of federal, state and
local income taxes on such reduced Total Payments would be greater than the
excess of (a) the net amount of the Total Payments without such reduction in the
Severance Payments but after deduction of the net amount of federal, state and
local income taxes (other than the Excise Tax) on such unreduced Total Payments,
over (b) the Excise Tax to which the Total Payments are subject. The
determination as to whether a reduction in Severance Payments is to be made
under this Section 6.2 and, if so, the amount of any such reduction shall be
made by the Company's auditors or by such other firm of certified public
accountants, benefits consulting firm or legal counsel as the Board may
designate prior to the Change in Control.

         The Company shall provide the executive with its calculations of the
amounts referred to in this Section 6.2 and such supporting materials as are
reasonably necessary for the Executive to evaluate the Company's calculations.

         6.3      The Company also shall pay to the Executive all legal fees and
expenses incurred by the Executive as a result of a termination which entitles
the Executive to the Severance Payments (including all such fees and expenses,
if any, incurred in disputing any such termination or in seeking in good faith
to obtain or enforce any benefit or right provided by this Agreement or in
connection with any tax audit or proceeding to the extent attributable to the
application of section 4999 of the Code to any payment or benefit provided
hereunder). Such payments shall be made within five (5) business days after
delivery of the Executive's written requests for payment accompanied with such
evidence of fees and expenses incurred as the Company reasonably may require.

         7.0      TERMINATION PROCEDURES AND COMPENSATION DURING DISPUTE.

         7.1      NOTICE OF TERMINATION. After a Change in Control and during
the term of this Agreement, any purported termination of the Executive's
employment (other than by reason of death) shall be communicated by written
Notice of Termination from one party hereto to the other party hereto in
accordance with Section 10.0 hereof. For purposes of this Agreement, a "Notice
of Termination" shall mean a notice which shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Executive's employment under the provision so indicated.

         7.2      DATE OF TERMINATION. "Date of Termination", with respect to
any purported termination of the Executive's employment after a Change in
Control during the term of this Agreement, shall mean:

         (A)      if the Executive's employment is terminated for Disability,
         thirty (30) days after Notice of Termination is given (provided that
         the Executive shall not have returned to the full-time performance of
         the Executive's duties during such thirty (30) day period), and

         (B)      if the Executive's employment is terminated for any other
         reason, the date specified in the Notice of Termination (which, in the
         case of a termination by the Company, shall not be less than thirty
         (30) days (except in the case of a termination for Cause).

         7.3      DISPUTE CONCERNING TERMINATION. If within fifteen (15) days
after any Notice of Termination is given, or, if later, prior to the Date of
Termination (as determined without regard to this Section 7.3), the party
receiving such Notice of Termination notifies the other party that a dispute
exists concerning the termination, the Date of Termination shall be the date on
which the dispute is finally resolved, either by mutual written agreement of the
parties by arbitrator's award, or, to the extent permitted by Section 14.0, by a
final judgment, order or decree of a court of competent jurisdiction on the
arbitrator's award (which is not appealable or with respect to which the time
for appeal therefrom has expired and no appeal has been perfected); provided
further that the Date of Termination shall be extended by a notice of dispute
only if such notice is given in good faith and the party giving such notice
pursues the resolution of such dispute with reasonable diligence.

         7.4      COMPENSATION DURING DISPUTE. If a purported termination occurs
following a Change in Control and during the term of this Agreement and such
termination is disputed in accordance with Section 7.3 hereof, the Company shall
continue to pay the Executive the full compensation in effect when the notice
giving rise to the dispute was given (including, but not limited to, salary) and
continue the Executive as a participant in all compensation, benefit and
insurance plans in which the Executive was participating when the notice giving
rise to the dispute was given, until the dispute is finally resolved in
accordance with Section 7.3 hereof. Amounts paid under this Section 7.4 are in
addition to all other amounts due under this Agreement (other than those due
under Section 5.2 hereof) and shall not be offset against or reduce any other
amounts due under this Agreement.

         8.0      NO MITIGATION. The Company agrees that, if the Executive's
employment by the Company is terminated during the term of this Agreement, the
Executive is not required to seek other employment or to attempt in any way to
reduce any amounts payable to the Executive by the Company pursuant to Section
6.0 or Section 7.4. Further, the amount of any payment or benefit provided for
in Section 6.0 (other than Section 6.1(ii) or Section 7.4 shall not be reduced
by any compensation earned by the Executive as the result of employment by
another employer, by retirement benefits, by offset against any amount claimed
to be owed by the Executive to the Company, or otherwise.

         9.0      SUCCESSORS; BINDING AGREEMENT.

         9.1      In addition to any obligations imposed by law upon any
successor to the Company, the Company will require any successor (whether direct
or indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. In any event this agreement shall be binding upon the Company
and any successors or assignee.

enforceable by the Executive's personal or legal representatives, executors,
administrators, successors, heirs,

distributees, devisees and legatees. If the Executive shall die while any amount
would still be payable to the Executive hereunder (other than amounts which, by
their terms, terminate upon the death of the Executive) if the Executive had
continued to live, all such amounts, unless otherwise provided herein, shall be
paid in accordance with the terms of this Agreement to the executors, personal
representatives or administrators of the Executive's estate.

                  of Termination for Good Reason by the Executive pursuant to
