               EMPLOYMENT AGREEMENT BETWEEN PICTURETEL CORPORATION
                                 AND LEWIS JAFFE

June 19, 2000

Mr. Lewis Jaffe
47 Gerald Road
Marblehead, MA 01945

Dear Lew:

On behalf of PictureTel Corporation (the "Company"), I am very pleased to offer
you an opportunity to immediately join our Company as the President and Chief
Operating Officer and a Corporate Officer of the Company reporting directly to
me.

The cash compensation in the offered position will be composed of two elements:
an annual base salary and an annual bonus opportunity under PictureTel's
Management Incentive Plan. The base salary for the position will be paid at the
biweekly rate of $10,769.23 (the equivalent of $280,000.00 annually based on 26
biweekly pay periods in the year). The offered base salary will be the minimum
paid while employed with the Company. As President and an Officer of the
Company, a full performance and compensation (salary, bonus, and equity) review
is completed by the Compensation Committee of the Board during the quarter
immediately following the close of each fiscal year and recommendations acted
upon as appropriate.

The payment of a bonus under the Management Incentive Plan is predicated on the
Company's achievement of the annual revenue and profitability objectives
established at the start of the fiscal year and your performance in meeting your
Individual Goals for the year. The bonus opportunity will be 0%-60% of base
salary for full performance in meeting the objectives for the year, but may
range up to 120% of base salary for performance in excess of the plan. The
bonus, if any, is determined and paid in the first quarter following the close
of the fiscal year.

The Company will offer you a cash sign-on bonus in the aggregate amount of
$100,000.00; to be paid as follows: $50,000.00 on July 1, 2000; $50,000.00 on
January 1, 2001. If you voluntarily terminate your employment with the Company
before the payment of all the sign-on bonus installments, those installments
remaining to be paid will be forfeited.

Effective immediately, the Company will put in place a special Executive Bonus
Program. You and the executive team will be eligible for bonus payments (the
amounts to be determined) for enhancing shareholder value by increasing the
Company's stock price to or above $10.00 per share for a period of no less than
thirty (30) consecutive trading days.

In addition, we will recommend to the Compensation Committee of the Board of
Directors that you be granted an option to purchase 300,000 shares of the Common
Stock of the Company ("Option"). The Option will vest over a four (4) year
period, with the first twelve and one-half (12.50) percent of the Option vesting
six (6) months following the date the option grant is approved and six and one-
quarter (6.25) percent of the Option vesting each full three (3) month period
thereafter. The purchase price of the Option will be determined by the
Compensation Committee on the day your option grant is approved and will be the
closing price as quoted on the National Market System of NASDAQ on that date.
Vesting shall be conditional on your continued full-time employment with the
company. All other conditions applicable to the Option shall be set forth in a
Stock Option Agreement representing the Option (which shall follow the terms of
the 1999 PictureTel Equity Plan) and such Stock Option Agreement shall be
delivered immediately following the day the Option is approved. As President,
additional option grants are subject to the annual total compensation review
discussed above.

In the event that your employment with the Company is involuntarily terminated
for any reason other than for Cause, you will be entitled to receive a
continuation of your then current base salary plus 50% of the then current
annual bonus target for a period of twelve (12) months ("Severance Period"). For
purposes of this letter, "Cause" shall be defined as and be limited to
conviction of a felony or willful misconduct or gross negligence in the
performance of duties which result in material harm to PictureTel. During the
Severance Period, the Company will maintain your eligibility to participate in
the Company's group medical and dental plans and will continue to contribute its
share of the costs of such plans at the same level as active employees. If you
wish to continue your medical and dental insurance coverage beyond the Severance
Period, you may do so for up to a total of eighteen (18) months (inclusive of
the Severance Period) pursuant to your rights under the Consolidated Budget
Reconciliation Act ("COBRA"). If you elect to continue coverage beyond the
Severance Period, you will be responsible for paying the full cost of the
coverage.

Further, the Company will enter into a separate Change in Control Agreement
("CIC Agreement") which will provide you with certain benefits in the event of
an involuntary termination due to a change in control. The CIC Agreement will
include certain triggering events and provide, but not be limited to, severance
equal to the sum of (a) your then current base salary, plus (b) the highest
bonus paid in the three years preceding the triggering events, paid over a
consecutive twenty-four (24) month period. The full acceleration of all unvested
stock options in the event of a change in control is to be specifically covered
in the Stock Option Agreement and will not be included in the CIC Agreement. The
CIC Agreement will be executed concurrently with your acceptance of our
employment offer and the commencement of work with the Company. In the event any
deal is concluded before the end of the calendar year 2000, the provisions of
the CIC Agreement will apply.

As an employee of the Company you will be entitled to participate in our medical
insurance benefit programs. We offer two options: (1) a competitive medical and
dental plan through Blue Cross Blue Shield of Massachusetts, or (2) membership
in the Harvard - Pilgrim Community Health Plan, a Health Maintenance
Organization. You will be responsible for a portion of the premium cost, with
payment arranged through payroll deductions. A Section 125 reimbursement plan to
help with daycare and non-reimbursed medical expenses is available at your
election, also through payroll deductions. In addition, the Company provides
long-term disability, accidental death and dismemberment, and life insurance
coverage (life benefit equal to two (2) times your annual salary). The premiums
for the disability and life insurance are paid one hundred (100) percent by the
Company. Finally, the Company offers a 401(k) Retirement Plan and a Section 423
Employee Stock Purchase Plan to all employees upon their becoming service
eligible. You will be entitled to paid holidays and vacation in accordance with
Company Policy.

This offer is contingent on your providing proof of eligibility for employment.
On your first day of employment, please bring with you either: (a) a valid U.S.
Passport, or (b) a birth certificate and a driver's license, or (c) an original
Social Security card and a driver's license.

Please indicate your acceptance of this offer and your anticipated start date by
completing and signing the enclosed copy of this letter, the PictureTel
Application for Employment, and the Proprietary Information Agreement. Please
return all signed documents to Larry Bornstein as soon as practical.

If you have any questions regarding this offer, please do not hesitate to call
Larry or me. We look forward to your joining and being an important member of
our team.

Sincerely,

Norman Gaut
Chairman, President and
Chief Executive Officer

                  EXECUTIVE OFFICER CHANGE IN CONTROL AGREEMENT

     THIS AGREEMENT dated June 19, 2000 is made by and between PictureTel
Corporation, a Delaware Corporation, (the "Company") and Lewis Jaffe, 47 Gerald
Road, Marblehead, MA 01945 ("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 that 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 December 31, 2001; provided, however, that
commencing on December 1, 2000 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 thirty-six (36)
months beyond the date 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, except as otherwise
agreed in writing between the Executive and the Company, including the
Employment Agreement dated November 9, 1999, 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 Change in
Control, (C) the date of termination by the Executive of the Executive's
employment for Good Reason (determined by treating the Potential Change in
Control as a Change in Control in applying the definition of Good Reason), 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,
(B) by reason of death or Disability, or (C) by the Executive without Good
Reason. The Executive's employment shall be deemed to have been terminated
following a Change in Control by the Company without Cause or by the Executive
with Good Reason 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 or if the Executive
terminates his employment with Good Reason prior to a Change in Control
(determined by treating a Potential Change in Control as a Change in Control in
applying the definition of Good Reason) if the circumstance or event which
constitutes Good Reason occurs at the direction (or action which constitutes a
direction) of such Person.

     (i) Subsequent to the Date of Termination, the Company shall make cash
     severance payments to the Executive over a twenty-four (24) month period in
     substantially equal bi-weekly installments, in an amount equal to two (2)
     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 twenty-four (24) 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 immediately prior to the Notice of Termination (without giving
     effect to any reduction in such benefits subsequent to a Change in Control
     which reduction constitutes Good Reason). 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 Executive without cost during the twenty-four (24) 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

<PAGE>   3

     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. Further, a Notice of Termination for Cause is
required to include a copy of a resolution duly adopted by the affirmative vote
of not less than three-quarters (3/4) of the entire membership of the Board at a
meeting of the Board which was called and held for the purpose of considering
such termination (after reasonable notice to the Executive and an opportunity
for the Executive, together with the Executive's counsel, to be heard before the
Board) finding that, in the good faith opinion of the Board, the Executive was
guilty of conduct set forth in clause (i) or (ii) of the definition of Cause
herein, and specifying the particulars thereof in detail.

     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) and, in the case of a termination
     by the Executive, shall not be less than fifteen (15) days nor more than
     sixty (60) days, respectively, from the date such Notice of Termination is
     given).

<PAGE>   4

     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. Failure of the
Company to obtain such assumption and agreement prior to the effectiveness of
any such succession shall be a breach of this Agreement and shall entitle the
Executive to compensation from the Company in the same amount and on the same
terms as the Executive would be entitled to hereunder if the Executive were to
terminate the Executive's employment for Good Reason after a Change in Control,
except that, for purposes of implementing the foregoing, the date on which any
such succession becomes effective shall be deemed the Date of Termination. In
any event this agreement shall be binding upon the Company and any successors or
assignee.

     9.2 This Agreement shall inure to the benefit of and be 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.

     10.0 NOTICES. For the purpose of this Agreement, notices and all other
communications provided for in the Agreement shall be in writing and shall be
deemed to have been duly given when delivered in hand or when delivered or
mailed by United States certified mail, return receipt requested, postage
prepaid, addressed to the respective addresses set forth below, or to such other
address as either party may have furnished to the other in writing in accordance
herewith, except that notice of change of address shall be effective only upon
actual receipt:

or discharged unless such waiver, modification or discharge is agreed to in
writing and signed by the Executive and such officer as may be specifically
designated by the Board. No waiver by either party hereto at any time of any
breach by the other party hereto of, or compliance with, any condition or
provision of this Agreement to be performed by such other party shall be deemed
a waiver of similar or dissimilar provisions or conditions at the same or at any
prior or subsequent time. No agreements or representations, oral or otherwise,
express or implied, with respect to the subject matter hereof have been made by
either party which are not expressly set forth in this Agreement. The laws of
the Commonwealth of Massachusetts shall govern the validity, interpretation,
construction and performance of this Agreement and the Agreement shall be an
instrument under seal. All references to sections of the Exchange Act or the

expiration of the term of this Agreement.

     12.0 VALIDITY. The invalidity or unenforceability or any provision of this
Agreement shall not affect the validity or enforceability of any other provision
of this Agreement, which shall remain in full force and effect. In addition, if

competent jurisdiction, then such provision shall be deemed modified to the
extent necessary to enable such provision to be valid and enforceable.

     13.0 COUNTERPARTS. This Agreement may be executed in several counterparts,
each of which shall be deemed to be an original but all of which together will
constitute one and the same instrument.

     14.0 SETTLEMENT OF DISPUTES; ARBITRATION. All claims by the Executive for
benefits under this Agreement shall be directed to the Board and shall be in
writing. Any denial by the Board of a claim for benefits under this Agreement
shall be delivered to the Executive in writing and shall set forth the specific
reasons for the denial and the specific provisions of this Agreement relied
upon. The Board then shall afford a reasonable opportunity to the Executive for
a review of the decision denying a claim and shall further allow the Executive
to appeal to the Board a decision of the Board within sixty (60) days after
notification by the Board that the Executive's claim has been denied. Any
further dispute or controversy arising under or in connection with this
Agreement shall be settled exclusively by arbitration in Boston, Massachusetts
in accordance with the rules of the American Arbitration Association then in
effect. Judgment may be entered on the arbitrator's award in any court having
jurisdiction; provided, however, that the Executive shall be entitled to seek
specific performance of the Executive's right to be paid until the Date of
Termination during the pendency of any dispute or controversy arising under or
in connection with this Agreement in such arbitration or by a proceeding in the
federal court in Boston or the Massachusetts state court in Essex County.
