Item 5. Other Events

On April 15, 1997, PictureTel Corporation (the "Company") announced that it had
entered into an Agreement and Plan of Merger dated as of April 15, 1997 (the
"Agreement"), among the Company, MultiLink, Inc., a Massachusetts corporation
("MultiLink"), and ML Acquisition Corp., a wholly-owned subsidiary of the
Company ("Subsidiary"). The Agreement provides for the Company to acquire
MultiLink through the merger of Subsidiary with and into MultiLink (the
"Merger"), which will remain the wholly-owned subsidiary of the Company. Under
the terms of the Agreement, each share of MultiLink common stock outstanding
(approximately 6,243,000 shares) will be exchanged for 0.56 of a share of
PictureTel common stock. Outstanding options to purchase MultiLink stock will be
converted at the exchange ratio into PictureTel options. Following the Merger,
MultiLink shareholders will own approximately 10% and PictureTel shareholders
will own approximately 90% of the combined Company's shares. The parties intend
that the Merger be accounted for as a "pooling of interests" and that it qualify
as a tax-free reorganization under the Internal Revenue Code. The Company also
entered into a Stockholders Agreement dated as of April 15, 1997 with holders of
approximately 72% of the outstanding shares of MultiLink in which such
stockholders agreed to vote their shares of MultiLink in favor of the Merger.
This description is qualified in its entirety by reference to the Agreement and
Plan of Merger and the Stockholders Agreement attached as exhibits.

                        continue to be governed by the laws of The Commonwealth
                        of Massachusetts, and the separate corporate existence
                        of the Merger Sub shall thereupon cease. From and after
                        the Effective Date, the identity, existence, purposes,
                        powers, objects, franchises, privileges, rights and

                        subscriptions and other cheeses in action, belonging to

                        vested in, the Surviving Corporation without further act
                        or deed; but the Surviving Corporation shall be deemed
                        to have assumed, and shall be liable for, all
                        liabilities and obligations of each of the Constituent
                        Corporations in the same manner and to the same extent

                        prior to the Effective Date, shall continue to be the
                        Charter of the Surviving Corporation, until duly amended
                        in accordance with law. On the Effective Date, the

                              (d) Converting Company Shares and Options. Upon
                        the effectiveness of the Merger, by virtue of the Merger
                        and without any action on the part of the holders
                        thereof, the outstanding Equity Securities of the
                        Company (other than (i) Equity Securities of the Company
                        held in the Company's treasury or by any of the
                        Company's Subsidiaries, (ii) such Equity Securities of
                        the Company, if any, as may then be owned by either
                        Buying Party and (iii) Dissenting Shares (as hereinafter
                        defined)) shall be canceled or converted in the manner
                        set forth below,

                                    (i) each outstanding share of Company Common
                              Stock shall be converted into and exchanged for
                              the right to receive the number of shares of
                              Parent Common Stock

                                           (ii) each Company Stock Option,
                              whether vested or unvested, shall be assumed by
                              Parent and shall constitute an option to acquire,
                              on the same terms and conditions as were
                              applicable under such Company Stock Option prior
                              to the Effective Date, the number (rounded down to
                              the nearest whole number) of shares of Parent
                              Common Stock as the holder of such Company Stock
                              Option would have been entitled to receive
                              pursuant to the Merger had such holder exercised
                              such option in full immediately prior to the
                              Effective Date (not taking into account whether or
                              not such option was in fact exercisable), at a
                              price per share equal to (x) the aggregate
                              exercise price for Company Common Stock otherwise
                              purchasable pursuant to such Company Stock Option
                              divided by (y) the number of shares of Parent
                              Common Stock purchasable pursuant to such Company
                              Stock Option.

                        provided, however, that (A) the Adjusted Escrow
                        Percentage of the shares of Parent Common Stock issuable
                        in the Merger with respect to shares of Company Common
                        Stock outstanding on the Effective Date shall be
                        delivered into escrow and held as specified in Section
                        6.11 (all such shares issuable pursuant to the Merger,
                        including the Escrowed Shares, or upon exercise of the
                        Company Stock Options, being referred to herein as the
                        "Parent Shares"; and said portion of the Parent Shares
                        subject to the escrow provisions of Section 6.11
                        together with all shares issued in payment or
                        distribution of any stock dividend on or stock split or
                        other recapitalization of, or in respect of, any such
                        escrowed shares, and any securities or other property
                        issued or distributed with respect to such shares in
                        connection with any merger, consolidation or liquidation
                        of Parent being referred to herein as the "Escrowed
                        Shares") and the Escrowed Shares shall be distributed,
                        to the Persons who as of and immediately prior to the
                        Closing held Company Common Stock, only upon release
                        from the Escrow Account as provided in Section 6.11 upon
                        and subject to resolution of the matters referred to in
                        Sections 6.11 and 9 and (B) no fractional shares of
                        Parent Common Stock shall be issued pursuant to the
                        Merger, with each Person otherwise entitled to such a
                        fractional share being entitled to cash, payable by
                        check of the Surviving Corporation, in an amount equal
                        to such fraction multiplied by the Formula Price Per
                        Share.

                              (e) Exchange Mechanics. As promptly as practicable
                        after the Effective Date, each holder (other than the
                        Company, if applicable) of any outstanding certificate
                        or certificates theretofore representing shares of
                        Company Common Stock converted in the Merger as
                        described in paragraph (d) above shall surrender the
                        same to Parent for cancellation (in each case together
                        with a duly executed letter of transmittal in form
                        reasonably acceptable to Parent and the Surviving
                        Corporation) and shall be entitled upon such surrender
                        to receive in exchange therefor a certificate or
                        certificates representing the number of Parent Shares to
                        which such holder is entitled pursuant to the Merger and
                        cash in lieu of any fractional share otherwise to be so
                        issued. Until so surrendered, each such outstanding
                        certificate or other Contractual Obligation which, prior
                        to the Effective Date, represented Company Common Stock
                        shall be deemed for all corporate purposes to evidence
                        ownership of the cash and number of Parent Shares into
                        which the shares of such Company Common Stock
                        represented thereby prior to the Effective Date have
                        been converted pursuant to the Merger.

                              (f) Options. Parent shall take all corporate
                        action necessary to reserve for issuance a sufficient
                        number of Parent Shares for delivery pursuant to the
                        terms set forth in Section 3.1.2(d)(ii). Subject to
                        Section 3.1.2(d)(ii), the Company Stock Options shall be
                        subject to the same vesting requirements, terms and
                        conditions after the Merger as apply to such options
                        prior to the Merger. It is the intention of the parties
                        that the Company Stock Options assumed by Parent shall
                        qualify as incentive stock options to the extent such
                        options qualified as incentive stock options immediately
                        prior to the Effective Date, and that the assumption by
                        Parent of the Company Stock Options qualifying for
                        incentive stock option treatment not constitute a
                        modification of such options. Subject to any applicable
                        limitations under the Securities Act of 1933, as
                        amended, and the rules and regulations thereunder (the
                        "Securities Act"), Parent shall file a Registration
                        Statement on Form S-8 (or any successor form), effective
                        as of the Effective Date, with respect to the Parent
                        Shares issuable upon exercise of the Company Stock
                        Options, and Parent shall use all reasonable efforts to
                        maintain the effectiveness of such registration
                        statement(s) (and maintain the current status of the
                        prospectus or prospectuses relating thereto) for so long
                        as such options shall remain outstanding. As soon as
                        practicable after the Effective Date, Parent shall
                        deliver to each holder of an


                                      -13-

                        outstanding Company Stock Option an appropriate notice
                        setting forth such holder's rights pursuant thereto.

                              (g) Cancellation of Treasury Stock and Stock held
                        by Parties. On the Effective Date, any and all Equity
                        Securities of the Company held by the Company or by any
                        of its Subsidiaries or by either Buying Party shall, by
                        virtue of the Merger and without any further action on
                        the part of the Company, its Subsidiaries or the Buying
                        Parties, be cancelled, retired and cease to exist and no
                        payment or other distribution shall be made with respect
                        thereto.

                              (h) Conversion of Merger Sub Shares. On the
                        Effective Date, each share of the $.01 par value common
                        stock of the Merger Sub ("Merger Sub Common Stock") then
                        issued and outstanding shall, by virtue of the Merger
                        and without any action on the part of the holders
                        thereof, be converted into one fully paid and
                        nonassessable share of the $.01 par value common stock
                        of the Surviving Corporation ("Surviving Corporation
                        Common Stock"). As promptly as practicable after the
                        Effective Date, each holder of any outstanding
                        certificate or certificates theretofore representing
                        shares of Merger Sub Common Stock shall surrender the
                        same to the Surviving Corporation and shall be entitled
                        upon such surrender to receive in exchange therefor a
                        certificate or certificates representing the number of
                        shares of Surviving Corporation Common Stock to which
                        such shareholder is entitled pursuant to the Merger.
                        Until so surrendered, each such outstanding certificate
                        which, prior to the Effective Date, represented Merger
                        Sub Common Stock shall be deemed for all corporate
                        purposes to evidence ownership of the number of shares
                        of Surviving Corporation Common Stock into which the
                        shares of the Merger Sub Common Stock represented
                        thereby prior to the Effective Date have been converted
                        pursuant to the Merger.

                              (i) Dissenting Shares. Notwithstanding anything to
                        the contrary in this Agreement, shares of Company Common
                        Stock outstanding immediately prior to the effective
                        time of the Merger and held by a shareholder who has not
                        voted in favor of the Merger or consented thereto in
                        writing and who has demanded appraisal rights for such
                        Equity Securities of the Company in accordance with the
                        provisions of Sections 85 through 98 of the
                        Business Corporation Law of The Commonwealth of
                        Massachusetts ("Dissenting Shares") shall not be
                        converted into the right to receive Parent Shares or
                        other consideration that may be

                        distributable in the Merger, unless such shareholder
                        fails to perfect or withdraws or otherwise loses his or

the premises) in connection with the indemnity provisions of Section 9 as they
relate to Target Securityholders generally, the escrow provisions of Section
6.11, the notice provisions of this Agreement and such other matters as are

elected by vote of holders of a majority of the Equity Securities of the Company
or, after the Merger, of the Parent Shares (calculated on a fully exercised and
converted basis) (each being referred to as a "Target Securityholders'
Representative"). By his execution hereof, J. Edward McAteer hereby accepts such
appointment and agrees to act as Target Securityholders' Representative
hereunder. The Target Securityholders' Representative shall not be liable to any
Target Securityholder, the Buying Parties or the Company or any other person
with respect to any action taken or omitted to be taken by the Target
Securityholders' Representative under or in connection with this Agreement

negligence, willful misconduct or bad faith on the part of the Target
Securityholders' Representative. Each of the Buying Parties and each of their
respective Affiliates (including, after the closing, the Company) shall be
entitled to rely on such appointment and treat the Target Securityholders'
Representative as the duly appointed attorney-in-fact of each Target
Securityholder. Each Target Securityholder who executes this Agreement or votes

confirms such appointment and authority and acknowledges and agrees that such
appointment is irrevocable and coupled with an interest, it being understood
that the willingness of the Buying Parties to enter into this Agreement is
based, in part, on the appointment of a representative to act on behalf of the
Target Securityholders.

4.    REPRESENTATIONS AND WARRANTIES OF THE COMPANY. The Company represents
and warrants to the Buying Parties as follows:

      4.1. Organization and Corporate Power. The Company and each of its
Subsidiaries is a corporation duly organized, validly existing and in good
standing under the laws of its jurisdiction of organization or incorporation,
and is qualified to do business as a foreign corporation in each jurisdiction
where such qualification is required and where the failure to be so qualified
could have a Company Material Adverse Effect. The Company and each of its
Subsidiaries have all required corporate power and authority to own or lease its
property, to carry on its business as presently conducted and proposed to be
conducted and to carry out the transactions contemplated hereby. The copies of
the Charter and By-laws of the Company and each of its Subsidiaries, which have
been furnished to Parent, are correct and complete and contain all amendments
through the date of this Agreement.

      4.2. Authorization and Enforceability. Subject only to the requirement
that this Agreement be approved by the Company's shareholders pursuant to the
Massachusetts Business Corporation Law, this Agreement and any other agreements,
instruments, or documents entered into by the Company pursuant to this Agreement

been duly authorized, executed and delivered by the Company and are the legal,
valid and binding obligations of the Company, enforceable in accordance with
their terms.

      4.3. Capitalization. (a) The entire authorized capital stock of the
Company consists of 15,000,000 shares of Common Stock, $0.01 par value per share
(the "Company Common Stock"), of which 6,242,806 shares are issued and
outstanding. The shares of Company Common Stock outstanding have been duly
authorized and are validly issued, fully paid and nonassessable and have been
offered, issued and sold by the Company in compliance with applicable state and
federal securities laws. No shares of Company Common Stock are held in the
Company's treasury which are available for resale.

      (b) Other than Company Stock Options to purchase an aggregate of 868,245
shares of Company Common Stock, there are no outstanding options, warrants,
Contractual Obligations or commitments of any character relating to the issued
or unissued capital stock of the Company or obligating the Company to issue or
sell any shares of capital stock of, or other equity interests in,

<PAGE>   23
the Company. There are no obligations, contingent or otherwise, of the Company
to repurchase, redeem or otherwise acquire any shares of capital stock of the

capital contribution, guaranty or otherwise) in any Subsidiary or any other
entity. Except as provided in the Stockholders Agreement or as imposed by
applicable securities laws, there are no restrictions on the transfer or voting
of any shares of the Company Common Stock.

      4.4. Subsidiaries. The Company has only the Subsidiaries listed in
Schedule 4.4. Such Schedule sets forth the name and jurisdiction of
incorporation or organization and capitalization of each such Subsidiary. The
Company is the record and beneficial holder of all of the issued and outstanding
shares of capital stock of each of its Subsidiaries, such shares have been duly
authorized and validly issued and are fully paid and nonassessable, and the
Company owns such shares free and clear of any Liens other than restrictions on
transfer imposed by applicable securities laws. There is no outstanding Equity
Security of any Subsidiary other than its shares of capital stock. The Company
has never been a Subsidiary of any other Person.

      4.5. Financial Statements. The Company has furnished to the Buying Parties
its audited balance sheets as of September 30, 1996, 1995 and 1994 and
statements of income and cash flows for the twelve months ended September 30,

financial position of the Company as of each such date and the results of its
operations for each such period then ended, subject, in the case of unaudited

audit adjustments which will not in the aggregate be material.

Most Recent Balance Sheet (rather than in any notes thereto) and (ii)
Liabilities which have arisen after the date of the Most Recent Balance Sheet in
the Ordinary Course of Business (none of which liabilities referred to under

                                      -25-
<PAGE>   30

Service (the "IRS") or Secretary of the Treasury), and the Company and each of
its subsidiaries have performed all material obligations required to be

counterclaims except as recorded as accounts payable, are current and
collectible and will be collected in accordance with their terms at their
recorded amounts, except as reflected as net of allowance for bad debts on the
face of the Most Recent Balance Sheet (rather than in any notes thereto or

and practice of the Company and its Subsidiaries. Such inventory reflected in
the Most Recent Balance Sheet and books and records of the Company is valued at
the lower of cost (on a first-in, first-out basis) or market in accordance with

inventory has been sold or disposed of except through sales in the Ordinary
Course of Business.

state any material fact required to be stated therein or necessary in order to

it shall be made, is false or misleading with respect to any material fact, or
shall omit to state any material fact necessary in order to make the statements
made therein not false or misleading, or omit to state any material fact
necessary to correct any statement in any earlier communication with respect to
the solicitation of proxies for the Special Meeting which has become false or
misleading. If at any time prior to the effective time of the Merger any event
relating to the Company or any of its Affiliates, officers or directors should
be discovered by the Company which should be set forth in an amendment to the
Registration Statement or a supplement to the Proxy Statement/Prospectus, the

arrangements), pursuant to which payments, severance, benefits or acceleration
of any of the foregoing may be required, directly or indirectly, as a result of
a change of control of the Company.

      4.29. Claims Against Directors and Officers. There is no action, suit,
proceeding, hearing, investigation, charge, complaint, claim or demand pending
or, to the knowledge of the Company, threatened (and no reasonable basis for any
of the foregoing) against any person who is now or has been at any time prior to
the date hereof an officer or director of the Company for acts or omissions in
such person's capacity as an officer or director of the

                                      -27-

Material Adverse Effect.

Company a complete and correct copy of its Charter and By-Laws, as amended to
date. Such Charter and By-Laws are in full force and effect. Neither Parent

breach or violation of, or any default or right or cause of action under the
Charter or By-Laws of either Buying Party or, assuming expiration or early
termination of the waiting period under the HSR Act, any Legal Requirement
applicable to either Buying Party. No approval, consent, waiver, authorization

the consummation of the transactions contemplated hereby by either Buying Party,
except for items which shall have been obtained or made and shall be in full
force and effect at the Closing.

      5.6. Investment Intent. Parent is acquiring the Equity Securities of the
Surviving Corporation to be acquired by Parent as a result of the Merger for

connection with, any public distribution of such Equity Securities in violation
of any federal or state securities law.

      5.7. Litigation. There is no action pending or, to the Buying Parties'
knowledge, threatened (i) against either Buying Party or any of its Affiliates
with respect to which there is a reasonable likelihood of a determination which
would have a material adverse effect on the ability of either Buying Party to
perform its obligations under this Agreement or (ii) which seeks to enjoin or
obtain damages in respect of the consummation of the transactions contemplated
hereby. Neither either Buying Party nor any of its Affiliates is subject to any
outstanding Governmental Orders which would have a material adverse effect on

Agreement.

fact required to be stated or incorporated by reference therein or necessary in
order to make the statements therein, in light of the circumstances under which
they were made, not misleading. The audited consolidated financial statements

      5.9. Brokers. No broker, finder, investment bank or similar agent is
entitled to any


                                      -29-

amendments or supplements thereto) is declared effective by the SEC, contain any

in order to make the statements included therein, in light of the circumstances
under which they were made, not misleading. The information supplied by Parent
for inclusion in the Proxy Statement/Prospectus will not, on the date the Proxy
Statement/Prospectus is first mailed to stockholders, at the time of the Special

such time and in light of the circumstances under which it shall be made, is
false or misleading with respect to any material fact, or will omit to state any
material fact necessary in order to make the statements therein not false or
misleading; or omit to state any material fact necessary to correct any
statement in any earlier communication with respect to the solicitation of
proxies for the Special Meeting which has become false or misleading. If at any

and other information with respect to the Company and its Subsidiaries as the
Buying Parties or any of their representatives shall reasonably request. In

order, and (iii) in the event that such protective order or other remedy is not
obtained by the Company, the disclosing Person will disclose only that portion
of the confidential information which the disclosing Person is legally required
to disclose, and the disclosing Person will use its best efforts to obtain
assurances that confidential treatment will be accorded to such information. In

<PAGE>   39
      from performing or cause the Company not to perform its covenants
      hereunder.

      6.7. Certain Notices. Prior to the Closing, each party will promptly upon
becoming aware thereof give the other parties written notice of any material
development affecting its business, financial condition or prospects and any
breach of or inaccuracy in any of its representations or warranties contained in
this Agreement; provided, however, that no such disclosure shall be deemed to
prevent or cure any breach of or inaccuracy in, or disclose any exception to,
any of the representations and warranties set forth herein.

      6.8. Preparation for Closing. Each party will use its best efforts to
bring about the fulfillment of each of the conditions precedent to the
obligations of the other parties hereto set forth in this Agreement. The Company
shall give the Buying Parties prompt notice of any demands received by the

reasonable efforts obtain all approvals, consents, waivers, authorizations or

contemplated hereby

      6.10. Pooling of Interests Accounting Treatment; Certain Tax Covenants.

            6.10.1. Pooling. The Company acknowledges that Parent intends to
      account for the Merger and the consummation of the transactions
      contemplated hereby as a "pooling of interests" under GAAP and principles
      applied by the SEC, all as from time to time in effect. The Company
      represents and warrants that it has not taken, and covenants that it will
      not take, any action which would preclude such accounting treatment from
      being used by Parent. Without limiting the generality of the foregoing,
      the Company acknowledges, represents, warrants and agrees that (a) the
      Company is not and has never been a division or more than 50%-owned
      Subsidiary of any corporation nor been part of an acquisition which was
      later rescinded, (b) the Company has not taken, within the previous two
      years, and will not take, prior to the Closing, any action (i) to change
      the equity interest of the voting common stock of the Company (or amend
      the terms of any Equity Security of the Company or of any Contractual
      Obligation relating thereto, including but not limited to the Company
      Option Plans) in contemplation of the transactions contemplated by this
      Agreement, including, without limitation, any additional issuance,
      exchange or retirement of any securities of the Company, (ii) to permit
      the Company to reacquire any shares of its voting common

                                      -35-
<PAGE>   40
      stock or (iii) to permit the Company or any Subsidiary of the Company to
      dispose of a significant portion of its assets in contemplation of the
      transactions contemplated by this Agreement, and (c) the ratio of the
      interest in the Company of each holder of Company Common Stock to each
      other holder of Company Common Stock will not be changed by the
      consummation of the transactions contemplated by this Agreement.

            6.10.2. Plan of Reorganization and other Tax Matters.

            (a) This  Agreement  shall  constitute a "plan of  reorganization"
      for purposes of Section 368 of the Code.

            (b) The parties hereto shall, and shall cause the Company to,
      provide such necessary information as any other party hereto may
      reasonably request in connection with the preparation of such party's Tax
      returns, or to respond to or contest any audit, prosecute any claim for
      refund or credit or otherwise satisfy any Legal Requirement relating to
      Taxes and the Company.

            (c) There shall be withheld from any amount payable hereunder such
      amounts as may be required to be withheld under applicable law.

            (d) Each of the Buying Parties and the Company shall use its best
      efforts to cause the Merger to be treated as a "reorganization" within the
      meaning of Section 368(a) of the Code.

      6.11. Escrow of Shares Pending Resolution of Certain Matters. Upon
consummation of the Merger, Parent shall deliver to The First National Bank of
Boston, as escrow agent (the "Escrow Agent"), a certificate representing the
Adjusted Escrow Percentage of the Parent Shares. The Escrowed Shares shall be
held and either released to the Target Securityholders or surrendered to the
Buying Parties according to the provisions of this Section 6.11. The Escrowed
Shares of each Target Securityholder shall be applied to indemnify and hold
harmless Parent and its Affiliates against and in respect of any and all Losses
specified in Section 9.1.1 for which the Buying Parties and their Affiliates are
entitled to indemnification pursuant to the provisions of Section 9, the amount
of such indemnification to be determined as provided in Section 9. Each Target
Securityholder shall be entitled to vote such Escrowed Shares as are, from time
to time, held for such Target Securityholder's account as Escrowed Shares and to
receive any dividend or distribution thereon (other than dividends or
distributions in the form of capital stock of Parent or otherwise falling within
the definition of "Escrowed Shares" hereunder, which shall be delivered to the
Escrow Agent and held as part of the Escrowed Shares).

            6.11.1. Term of Escrow. Except as provided in Section 6.11.3, the
      Escrowed Shares shall not be released from escrow until the earlier of (i)
      the date on which Parent's independent auditors shall report on their
      audit of Parent's financial statements for the fiscal year of Parent
      during which the Closing occurs, or (ii) the first anniversary of the


                                      -36-
<PAGE>   41
      Closing Date (such earlier date being hereinafter sometimes referred to as
      the "Release Date").

            6.11.2. Formula for Number of Escrowed Shares to be Returned to
      Parent. The number of Escrowed Shares to be returned to Parent in respect
      of each Loss for which it is entitled to indemnity hereunder shall be
      computed by dividing the dollar amount of the Target Securityholders'
      liability in respect of such Loss by the dollar amount of the Formula
      Price Per Share (subject to appropriate adjustment in the event of a stock
      dividend on, or stock split or combination of shares or other
      recapitalization of, or in respect of, the Escrowed Shares or in the event
      that other securities or property have been deposited in escrow in
      connection with any merger, consolidation or liquidation of Parent); and
      such Shares to be so returned to Parent shall be allocated among the
      Target Securityholders in proportion to their then respective interests in
      the Escrowed Shares.

            6.11.3. Certification of Losses, Return of Shares to Parent and
      Delivery of Balance to the Target Securityholders.

                  6.11.3.1. Parent shall provide written notice to the Target
            Securityholders' Representative of the occurrence of a Loss to which
            it is entitled to indemnification (which notice shall specify the
            circumstances of such Loss and the number of Escrowed Shares to be
            applied in respect thereof). Target Securityholders' Representative
            shall, within 30 days after delivery of such notice, (A) provide
            written notice to Parent pursuant to Section 6.11.3.2(i) or (ii) or
            (B) jointly with Parent instruct the Escrow Agent to apply all or
            the specified portion of the Escrowed Shares to the payment,
            reimbursement, settlement or discharge of such Loss.

                  6.11.3.2. Within 30 days after delivery of the notice to
            Target Securityholders' Representative referred to in
            Section 6.11.3.1, Target Securityholders' Representative may
            provide written notice to Parent:

                        (i) questioning the propriety of such proposed
                  application, in which case such question shall be resolved
                  under the Commercial Arbitration Rules of the American
                  Arbitration Association (the "AAA") by an arbitral tribunal
                  composed of three arbitrators, at least one of whom shall be
                  an attorney experienced in corporate transactions, appointed
                  by agreement of the parties in accordance with said Rules. In
                  the event the parties fail to agree upon a panel of
                  arbitrators from the first list of potential arbitrators
                  proposed by the AAA, the AAA will submit a second list in
                  accordance with said Rules. In the event the parties shall
                  have failed to agree upon a full panel of arbitrators from
                  said second list, any remaining arbitrators to be selected
                  shall be appointed by the AAA in accordance with said Rules.
                  If, at the time of


                                      -37-
<PAGE>   42
                  the arbitration, the parties agree in writing to submit the
                  dispute to a single arbitrator, said single arbitrator shall
                  be appointed by agreement of the parties in accordance with
                  the foregoing procedure, or, failing such agreement, by the
                  AAA in accordance with said Rules. The arbitrators shall
                  determine (A) the amount, if any, of such proposed application
                  which is proper, and (B) the amount to be borne by each party
                  and the party or parties and who shall bear the expense of
                  such determination (which shall be allocated to the Target
                  Securityholders in the proportion that the amount of the
                  application designated by such arbitrators to be borne by the
                  Target Securityholders bears to the amount originally sought
                  by Parent) and shall be conclusive on all parties; or

                        (ii) that the Target Securityholders dispute and intend
                  to defend the Liability, obligation, claim or Action giving
                  rise to such Loss or potential Loss, provided that, and for so
                  long as, such defense is being conducted by such Target
                  Securityholders at their expense and in a manner reasonably
                  deemed by Parent to be satisfactory and effective to protect
                  it against such Loss.

                  6.11.3.3. The Escrowed Shares, or any balance thereof held by
            the Escrow Agent as to which notice shall not have been given by
            Parent as aforesaid on or prior to the Release Date shall be
            delivered to the Target Securityholders not more than fifteen days
            after the Release Date and such Shares to be so returned shall be
            allocated among the Target Securityholders in proportion to their
            then respective interests in the Escrowed Shares. Any Escrowed
            Shares held by the Escrow Agent on the Release Date, the application
            of which to an indemnifiable Loss has been deferred pursuant to
            clause (i) or (ii) of Section 6.11.3.2 above shall, upon final
            determination or settlement of the Loss being determined or
            contested, be applied thereto and any balance delivered to the
            Target Securityholders in proportion to their then respective
            interests in the Escrowed Shares. Parent shall promptly notify the
            Escrow Agent on or before the Release Date indicating the number of
            Escrowed Shares the application of which has been deferred pursuant
            to clause (i) or (ii) of Section 6.11.3.2 above and, if Parent fails
            to give such notice within 10 days after the Release Date Target
            Securityholders' Representative may so notify the Escrow Agent.

      6.12. Affiliate Agreements. Each of Parent and the Company shall deliver
to the other, no later than 45 days after the execution of this Agreement, a
letter (an "Affiliate Letter") identifying all persons who may be deemed to be,
on or prior to the Effective Date, "affiliates" of Parent or the Company,
respectively, for purposes of Rule 145 under the Securities Act or otherwise
under applicable SEC accounting releases with respect to pooling-of-interests
accounting treatment. Each of Parent and the Company shall cause each person who
is identified as an "affiliate" in its Affiliate Letter to deliver to Parent, on
or before the date which is 30 days


                                      -38-
<PAGE>   43
prior to the Effective Date, a written agreement in connection with restrictions
on affiliates under Rule 145 and pooling of interests accounting treatment (an
"Affiliate Agreement"), in substantially the form of Exhibit A.

      6.13. Further Assurances. Each party, upon the request from time to time
of any other party hereto after the Closing, and without further consideration,
will do each and every act and thing as may be necessary or reasonably requested
to consummate the transactions contemplated hereby in an orderly fashion.

      6.14. Directors and Officers Indemnification. From and after the Effective
Date, Parent and Surviving Corporation shall indemnify, defend and hold harmless
each person who is now or has been at any time prior to the date hereof, an
officer or director of the Company (collectively, the "D&O Group") to the same
extent that such officer or director is indemnified by the Company pursuant to
the Company's Charter and By-Laws, as in effect on the date hereof, for acts or
omissions in such person's capacity as an officer or director of the Company
occurring on or prior to the Effective Date, provided that (i) the D&O Group may
retain only one law firm to represent them with respect to any single action,
which firm shall be reasonably satisfactory to Parent and Surviving Corporation,
unless there is, under applicable standards of professional conduct, conflict on
any significant issue between the positions of any two or more members of the
D&O Group, (ii) Parent and Surviving Corporation shall pay the reasonable fees
and expenses of such counsel and (iii) Parent and Surviving Corporation shall
not be liable for any settlement effected without their written consent.

      6.15. Expenses. Within ten calendar days of the date hereof, the Company
shall provide to Parent a good faith estimate and description of the expenses of
the Company and its Subsidiaries which the Company expects to incur, or has
incurred, in connection with the transactions contemplated by this Agreement.

      agreement made by or on behalf of either Buying Party in this Agreement or

      provided, however, that the indemnification provided pursuant to this
      Section 9.1.2 shall be subject to the provisions of Section 9.3.2.

      9.2. Time Limitation on Indemnification. Notwithstanding the foregoing, no

      arising out of the representations or warranties contained in Sections
      4.1, 4.2, 4.3, 4.4, 4.9, 4.18 and 4.20, (ii) for any breach of any
      covenant or agreement made by or on behalf of the Company in this

      this Agreement, or (iii) based on fraud, or which arise out of or are
      attributable to acts or omissions taken or made prior to Closing in
      connection with the Business that constitute willful misconduct or
      malfeasance, gross negligence or a violation of applicable Legal
      Requirements for which criminal liability may be assessed, or (iv) the
      matter referred to in Item E of Schedule 4.6, no Target Securityholder as

      Party or any of their respective Affiliates as Indemnitees in respect of
      any Loss of a type identified in Section 9.1.1 incurred by either Buying
      Party or any of their respective Affiliates as Indemnitee unless the
      aggregate cumulative total of all such Losses incurred by either Buying
      Party or any of their respective Affiliates as Indemnitee exceeds
      $500,000, whereupon each Buying Party and each of their respective

      recourse against the assets of the Target Securityholders in respect of
      their indemnification obligations under this Section 9 for those Losses
      specified in Section 9.1.1 and 9.4 (including expenses), but rather the
      sole recourse for collection in respect of such indemnification
      obligations in respect of Losses specified in Section 9.1.1 shall be
      limited to application of the Escrowed Shares as provided in


                                      -45-
<PAGE>   50
      Section 6.11 and as so limited the indemnification obligations of the
      Target Securityholders shall be joint but not several. Notwithstanding
      anything herein to the contrary, except with respect to claims based on
      fraud or which arise out of or are attributable to acts or omissions taken
      or made prior to Closing in connection with the Business that constitute
      willful misconduct, gross negligence or a violation of applicable Legal
      Requirements for which criminal liability may be assessed, , the rights of
      the Buying Parties, the Surviving Corporation and the Indemnitees under
      this Section 9 shall be the exclusive remedy of such Persons with respect
      to claims resulting from or relating to any misrepresentation, breach of
      any representation or warranty or failure to perform any covenant or
      agreement of the Company contained in this Merger Agreement.

            9.3.2. The Buying Parties. Except with respect to claims (i) arising
      out of the representations or warranties contained in Sections 5.1, 5.2,
      5.4 and 5.7, (ii) for any breach of any covenant or agreement made by or
      on behalf of the Buying Parties in this Agreement or in any other
      agreement or instrument delivered pursuant to this Agreement, or (iii)
      based upon fraud or which arise out of or are attributable to acts or
      omissions taken or made prior to Closing in connection with the Business
      that constitute willful misconduct or malfeasance, gross negligence or a
      violation of applicable Legal Requirements for which criminal liability
      may be assessed, neither Buying Party shall have any obligation to
      indemnify any Target Securityholder as Indemnitee in respect of any Loss
      of a type specified in Section 9.1.2 incurred by any Target Securityholder
      as Indemnitee unless the aggregate cumulative total of all such Losses
      incurred by any Target Securityholder as Indemnitee exceeds $500,000
      whereupon the Target Securityholders as Indemnitees shall be entitled to
      indemnification for the entire aggregate cumulative amount of such Losses
      described above. With respect to claims referred to in clauses (i), (ii)
      or (iii) of the immediately preceding sentence, the minimum dollar
      limitation shall be $100,000.

            Any payments made by the Buying Parties as Indemnifying Parties
      hereunder shall (i) be made through the issuance of shares of Parent
      Common Stock at a per share value equal to the Formula Price Per Share and
      (ii) not be in excess of the amount permitted in respect of transactions
      accounted for as a pooling under Accounting Principles Board Opinion No.
      16 and interpretations thereof issued by the American Institute of
      Certified Public Accountants on or prior to the date hereof as determined
      by Parent's independent auditors.

      9.4. Third Party Claims. Promptly after the receipt by any Indemnitee of
notice of the commencement of any Action against such Indemnitee by a third
party, such Indemnitee shall, if a claim with respect thereto is or may be made
against any Indemnifying Party pursuant to this Section 9, use reasonable
efforts to give the Indemnifying Parties written notice thereof. The failure to
give such notice shall not relieve any Indemnifying Party from any obligation
hereunder except where, and then solely to the extent that, such failure
actually and materially prejudices the rights of such Indemnifying Party. Such
Indemnifying Party shall have the right


                                      -46-
<PAGE>   51
to defend such claim, at such Indemnifying Party's expense and with counsel of
its choice reasonably satisfactory to the Indemnitee, provided that (a) the
Indemnifying Party so notifies the Indemnitee within 30 days after receipt of
such notice, (b) the claim involves only money damages and does not seek
injunctive or other equitable relief, (c) settlement of, or an adverse judgment
with respect to, such claim is not, in the good faith judgment of the
Indemnitee, reasonably likely to establish a precedent adverse to the continuing
business interests of the Indemnitee, and (d) the Indemnifying Party conducts
the defense of such claim actively and diligently. So long as the Indemnifying
Party is conducting the defense of such claim as provided in the previous
sentence, the Indemnitee may retain separate co-counsel at its sole cost and
expense and may participate in defense of such claim, and neither the
Indemnifying Party nor the Indemnitee will consent to the entry of any judgment
or enter into any settlement with respect to such claim without the prior
written consent of the other. In the event the Indemnifying Party does not or
ceases to conduct defense of such claim as so provided, (x) the Indemnitee may
defend against and, with the consent of the Indemnifying Party, which shall not
be unreasonably withheld, consent to the entry of any judgment or enter into any
settlement with respect to, such claim in any manner it may reasonably deem to
be appropriate, (y) the Indemnifying Party will reimburse the Indemnitee
promptly and periodically for the costs of defending against such claim,
including attorneys' fees and expenses, and (z) the Indemnifying Party will
remain responsible for any Losses the Indemnitee may suffer as a result of such
claim to the full extent provided in this Section 9.

      9.5.  Nature of Indemnification  Payments.  Any and all  indemnification
payments  or  offsets  pursuant  to this  Section 9  shall be  deemed  for all
purposes to be adjustments to the Aggregate Consideration Amount.

10.   CONSENT TO JURISDICTION; JURY TRIAL WAIVER.

      10.1. Consent to Jurisdiction. Each party to this Agreement, by its
execution hereof, (i) hereby irrevocably submits, and agrees to cause each of
its Subsidiaries to submit, to the exclusive jurisdiction of the state courts of
The Commonwealth of Massachusetts (or the United States District Court located
in Massachusetts) for the purpose of any Action arising out of or based upon
this Agreement or any Closing Agreement or relating to the subject matter hereof
or thereof, (ii) hereby waives, and agrees to cause each of its Subsidiaries to
waive, to the extent not prohibited by applicable law, and agrees not to assert,
and agrees not to allow any of its Subsidiaries to assert, by way of motion, as
a defense or otherwise, in any such Action, any claim that it is not subject
personally to the jurisdiction of the above-named courts, that its property is
exempt or immune from attachment or execution, that any such proceeding brought
in one of the above-named courts is improper, or that this Agreement or any
other Closing Agreement, or the subject matter hereof or thereof may not be
enforced in or by such court and (iii) hereby agrees not to commence or to
permit any of its Subsidiaries to commence any Action arising out of or based
upon this Agreement or any Closing Agreement or relating to the subject matter
hereof or thereof other than before one of the above-named courts nor to make
any motion or take any other action seeking or intending to cause the transfer
or removal of any such Action to any court


                                      -47-
<PAGE>   52
other than one of the above-named court whether on the grounds of inconvenient
forum or otherwise. Each party hereby consents to service of process in any such
proceeding in any manner permitted by Massachusetts law, and agrees that service
of process by registered or certified mail, return receipt requested, at its
address specified pursuant to Section 12.8 is reasonably calculated to give
actual notice.

      10.2. Waiver of Jury Trial. To the extent not prohibited by applicable law
which cannot be waived, each of the parties hereto hereby waives, and agrees to
cause each of its Subsidiaries to waive, and covenants that neither it nor any
of its Subsidiaries will assert (whether as plaintiff, defendant or otherwise)
any right to trial by jury in any forum in respect of any issue or Action
arising out of or based upon this Agreement or any other Closing Agreement or
the subject matter hereof or thereof or in any way connected with or related or
incidental to the transactions contemplated hereby, in each case whether now
existing or hereafter arising. Any party hereto may file an original counterpart
or a copy of this Section 10.2 with any court as written evidence of the consent
of each such party to the waiver of its right to trial by jury.

      Closing shall not have occurred on or before August 31, 1997 by reason of

<PAGE>   53
      from the Company breaching any representation, warranty, covenant or
      agreement contained in this Agreement), provided that such date shall be
      extended to September 30, 1997 with the consent of the Company upon
      request of Parent, which consent shall not be unreasonably withheld., or
      (iii) in the event the Company receives an unsolicited proposal with
      respect to such a transaction from any corporation, partnership or other
      entity or group (other than the Buying Parties and their designees) and is

shall be deemed to have been material and relied upon by the parties hereto,
notwithstanding any investigation made by or on behalf of any of the parties
hereto or any opportunity therefor or any actual or constructive knowledge
thereby obtained, and shall survive the execution and delivery of this Agreement
and the Closing until the Release Date or, in the case of Section 9.1.1(b),
provided that if written notice of a claim has been given prior to the Release
Date, then relevant representations, warranties, covenants or agreements shall
survive as to such claim until such claims have been finally resolved. Neither
the period of survival nor the liability of any party with respect to such
party's representations, warranties covenants and agreements shall be reduced by
any investigation made at any time by or on behalf of any party.

      12.4. Independence of Representations and Warranties. The parties hereto
intend that each representation, warranty and covenant contained herein shall
have independent significance. If any party has breached any representation,
warranty or covenant contained herein in any respect, the fact that there exists
any other representation, warranty or covenant relating to the same subject
matter (regardless of the relative levels of specificity) which the party has
not breached shall not detract from or mitigate the fact that such party is in
breach of the first representation, warranty or covenant.

      12.5. Severability. In the event that any provision hereof would, under
applicable law, be invalid or unenforceable in any respect, such provision shall
(to the extent permitted under applicable law) be construed by modifying or
limiting it so as to be valid and enforceable to the maximum extent compatible
with, and possible under, applicable law. The provisions hereof are severable,
and in the event any provision hereof should be held invalid or unenforceable in
any respect, it shall not invalidate, render unenforceable or otherwise affect
any other provision hereof.

PictureTel Corporation
100 Minuteman Road
Andover, MA 01810

      Re:  Merger Agreement

Ladies and Gentlemen:

      PictureTel Corporation, a Delaware corporation ("Parent"), ML Acquisition
Corp., a Massachusetts corporation and wholly-owned subsidiary of Parent
("Merger Sub"), and MultiLink, Inc., a Massachusetts corporation (the
"Company"), have entered into an Agreement and Plan of Merger dated April , 1997
(the "Merger Agreement"), pursuant to which Merger Sub would be merged with and
into the Company (the "Merger"), and each outstanding share of Company Common
Stock would be converted into the right to receive shares of Parent Common
Stock. Capitalized terms used herein and not defined have the meanings assigned
to them in the Merger Agreement.

      The undersigned has been advised that as of the date the Merger is
submitted to stockholders of the Company for approval, the undersigned may be an
"affiliate" of the Company, as the term is defined for purposes of paragraph (c)
of Rule 145 of the Securities and Exchange Commission (the "SEC") under the
Securities Act of 1933, as amended (the "Securities Act") and may be deemed an
"affiliate" of the Company for purposes of qualifying the Merger for pooling of
interests accounting treatment under Opinion 16 of the Accounting Principles
Board and applicable SEC rules and regulations, although nothing contained
herein shall be construed as an admission of either such fact.

      Parent has requested the undersigned to represent and agree, and the
undersigned represents and agrees, with Parent as follows:

      1.       Pooling.

      From and after 30 days prior to the Effective Time of the Merger, the
undersigned will not sell, transfer, exchange or otherwise, directly or
indirectly, dispose of, or reduce the risk of loss (by short sale or otherwise)
or enter into any contract or other arrangement with respect to,


                                      -55-
<PAGE>   60
or consent to the sale or exchange of or other disposition of any interest in,
any securities of the Company or Parent until after such time as Parent has
published financial results covering at least 30 days of combined operations of
Parent and the Company after the Effective Time of the Merger in the form of a
quarterly earnings report, an effective registration statement filed with the
SEC, a report to the SEC on Form 10-K, 10-Q or 8-K, or any other public filing
or announcement which includes such combined results of operations. The
undersigned understands that certificates representing the shares of Parent
Common Stock, if any, received by the undersigned in the Merger will be placed
on the "stop-transfer list" maintained by Parent's transfer agent and will
remain so listed until the publication of such financial results and that there
will be placed on the certificate(s) representing such stock, or any
certificates delivered in substitution therefor, a legend stating in substance:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED ONLY IN
      COMPLIANCE WITH THE CONDITIONS SPECIFIED IN A LETTER AGREEMENT DATED AS OF
      _________, 1997 RELATING THERETO, A COPY OF WHICH IS ON FILE WITH THE
      SECRETARY OF PICTURETEL CORPORATION."

      Parent agrees and covenants that (i) Parent will use its reasonable best
efforts to publish financial results covering at least 30 days of combined
operations of Parent and the Company after the Effective Time of the Merger, as
soon as practicable and in no event later than 45 days after the end of the
first fiscal quarter which includes at least 30 days of such combined operations
after the Effective Time if such 30 days is included in any of the first three
fiscal quarters of Parent, and in no event later than 90 days after the end of
the first fiscal quarter which includes at least 30 days of combined operations
of Parent and the Company if such 30 days is included in the fourth fiscal
quarter of Parent; and (ii) promptly after such publication the stop transfer
instructions and legends referred to above shall be terminated or removed.

      2.       Rule 145.

      The undersigned has been advised that the issuance of shares of Parent
Common Stock pursuant to the Merger will be registered under the Securities Act
pursuant to a registration statement on Form S-4. The undersigned has also been
advised that, if the undersigned is in fact an "affiliate" of the Company at the
time the Merger is submitted to a vote of the stockholders of the Company, Rule
145 under the Securities Act will restrict the undersigned's sales of shares of
Parent Common Stock, if any, received in the Merger. The undersigned has been
advised that if the undersigned is so subject to Rule 145, the undersigned may
not sell or otherwise dispose of any shares of Parent Common Stock except in
accordance with Rule 145(d) under the Securities Act or pursuant to an effective
registration statement under the Securities Act or an exemption from the
registration requirements of the Securities Act.

      The undersigned understands and agrees that:


                                      -56-
<PAGE>   61
               (i) Parent is under no obligation to register the sale, transfer
      or other disposition of the shares of Parent Common Stock to be received
      by the undersigned in the Merger except as set forth in written
      agreements, if any, with the undersigned which have been entered into by
      Parent or which have been specifically assumed by Parent.

               (ii) Stop transfer instructions will be given to the transfer
      agent of Parent with respect to the shares of Parent Common Stock to be
      received by the undersigned in the Merger, and there will be placed on the
      certificate representing such stock, or any certificates delivered in
      substitution therefor, a legend stating in substance:

      "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
      TRANSACTION TO WHICH RULE 145 UNDER THE SECURITIES ACT OF 1933 (THE "ACT")
      APPLIES. THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY BE TRANSFERRED
      ONLY IN ACCORDANCE WITH RULE 145(D) OR PURSUANT TO AN EFFECTIVE
      REGISTRATION STATEMENT OR EXEMPTION FROM REGISTRATION UNDER THE ACT."

               (iii) Unless the transfer by the undersigned of the shares of
      Parent Common Stock is a sale made in conformity with the provisions of
      Rule 145(d), or is made pursuant to a registration statement under the
      Securities Act, Parent reserves the right to put an appropriate legend on
      the certificate issued to a transferee.

      In connection with the foregoing, Parent agrees as follows:

               (i) For so long as and to the extent necessary to permit the
      undersigned to sell the shares of Parent Common Stock pursuant to Rule 145
      and, to the extent applicable, Rule 144 under the Securities Act, Parent
      shall use reasonable best efforts to file, on a timely basis, all reports
      required to be filed with the Securities and Exchange Commission ("SEC")
      by it pursuant to Section 13 of the Exchange Act, so long as it is subject
      to such requirement, furnish to the undersigned upon request a written
      statement as to whether Parent has complied with such reporting
      requirements during the 12 months preceding any proposed sale under Rule
      145 and otherwise use its reasonable efforts to permit such sales pursuant
      to Rule 145 and Rule 144. Parent has filed, on a timely basis, all reports
      required to be filed with the SEC under Section 13 of the Securities
      Exchange Act of 1934, as amended, during the preceding 12 months.

               (ii) Parent agrees that the stop transfer instructions and
      legends referred to above shall be terminated or removed if the
      undersigned shall have delivered to Parent a copy of a letter from the
      staff of the SEC or an opinion of counsel with recognized expertise in
      securities law matters, in form and substance satisfactory to Parent, to
      the effect that such instructions and legends are not required for the
      purposes of the Securities Act.

      This letter agreement shall be governed by and construed in accordance
      with the laws of


                                      -57-
<PAGE>   62
the State of Delaware.

      This letter agreement shall terminate if and when the Merger Agreement is
terminated according to its terms.

      Please indicate your agreement with the foregoing by signing the
acknowledgment below on the enclosed copies of this letter, and returning the
same to the undersigned, whereupon this letter agreement shall become an
effective agreement between Parent and the undersigned.

                                          Very truly yours,

                             STOCKHOLDERS AGREEMENT



           STOCKHOLDERS AGREEMENT, dated as of April 15, 1997 (the "Agreement"),
between the undersigned holders (the "Holders") of shares of the common stock,
$.01 par value (the "Company Common Stock"), of MultiLink, Inc., a Massachusetts
corporation (the "Company"), and PictureTel Corporation, a Delaware corporation
("Parent").

                                    RECITALS

           The Company, Parent and ML Acquisition Corp., a Massachusetts
corporation and a wholly-owned subsidiary of Parent ("Merger Sub"), propose to
enter into an Agreement and Plan of Merger dated the date hereof (the "Merger
Agreement"; capitalized terms not otherwise defined herein being used herein as
therein defined), pursuant to which Merger Sub would be merged (the "Merger")
with and into the Company, and each outstanding share of Company Common Stock
would be converted into the right to receive shares ("Parent Shares") of Parent
Common Stock; and

           As a condition of its entering into the Merger Agreement, Parent has
requested each Holder to agree, and each Holder has agreed, to enter into this
Agreement.


                                    AGREEMENT

            NOW, THEREFORE, the parties hereto agree as follows:

           1.     Representations and Warranties of the Holders.  Each Holder
represents and warrants, severally and not jointly, to Parent as follows:

           (a) Ownership of Securities. Each Holder is the record and beneficial
owner of the number of shares of Company Common Stock (the "Existing
Securities") (together with any shares of Company Common Stock or other
securities of the Company hereafter acquired by the Holder, the "Subject
Securities") set forth on Schedule I to this Agreement. Such Holder does not own
any securities of the Company on the date hereof other than the Existing
Securities and options, if any, to purchase shares of Common Stock as set forth
on Schedule I. The Holder has sole voting power and sole power to issue
instructions with respect to the voting of the Existing Securities, sole power
of disposition, sole power of exercise or conversion and the sole power to
demand appraisal rights, in each case with respect to all of the Existing
Securities and, on the date of the Special Meeting, will have sole voting power
and sole power to issue
<PAGE>   2
instructions with respect to the voting of all of such Holder's Subject
Securities, sole power of disposition, sole power of exercise or conversion and
the sole power to demand appraisal rights, in each case with respect to all of
such Holder's Subject Securities.

           (b) Power; Binding Agreement. Each Holder has full power and
authority to enter into and perform all of such Holder's obligations under this
Agreement. This Agreement has been duly and validly executed and delivered by
such Holder and constitutes a valid and binding agreement of such Holder,
enforceable against such Holder in accordance with its terms, except that (i)
such enforcement may be subject to applicable bankruptcy, insolvency or other
similar laws, now or hereafter in effect, affecting creditors' rights generally,
and (ii) the remedy of specific performance and injunctive and other forms of
equitable relief may be subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought.

           (c) No Conflicts. No filing by the Holder with, and no permit,
authorization, consent or approval of, any state or federal public body or
authority is necessary to be obtained by the Holder for the execution of this
Agreement by such Holder and the consummation by such Holder of the transactions
contemplated hereby. Neither the execution and delivery of this Agreement by
such Holder nor the consummation by such Holder of the transactions contemplated
hereby nor compliance by such Holder with any of the provisions hereof shall
conflict with or result in any breach of any applicable corporate, partnership
or other organizational documents applicable to such Holder, result in a
violation or breach of, or constitute (with or without notice or lapse of time
or both) a default (or give rise to any third-party right of termination,
cancellation, material modification or acceleration) under any of the terms,
conditions or provisions of any note, bond, mortgage, indenture, license,
contract, commitment, arrangement, understanding, agreement or other instrument
or obligation of any kind to which such Holder is a party or by which such
Holder's properties or assets may be bound or violate any order, writ,
injunction, decree, judgment, order, statute, rule or regulation applicable to
such Holder or any of such Holder's properties or assets.

           (d) No Liens. The Existing Securities are now and, at all times
during the term hereof, the Subject Securities will be held by such Holder, or
by a nominee or custodian for the benefit of such Holder, free and clear of all
Liens, claims, security interests, proxies, voting trusts or agreements,
understandings or arrangements or any other encumbrances whatsoever, except for
any encumbrances arising hereunder.

           2. Agreement to Vote Shares. At every meeting of the stockholders of
the Company called with respect to any of the following, and at every
adjournment thereof, and on every action or approval by written consent of the
stockholders of the Company with respect to any of the following, each Holder,
severally and not jointly, agrees that it shall vote all the Subject Securities
that it beneficially owns on the record date of any such vote: (i) in favor of
the Merger, the execution and delivery of the Merger Agreement and the approval
of the terms thereof and each of the other transactions contemplated by the
Merger Agreement and (ii) against


                                      -2-
<PAGE>   3
the following actions (other than the Merger and the transactions contemplated
by the Merger Agreement): (1) any extraordinary corporate transaction, such as a
merger, consolidation or other business combination involving the Company or its
subsidiaries; (2) a sale, lease or transfer of a material amount of assets of
the Company or its subsidiaries or a reorganization, recapitalization,
dissolution or liquidation of the Company or its subsidiaries; (3) (a) any
change in the majority of the board of directors of the Company; (b) any
material change in the present capitalization of the Company or any amendment of
the Company's Certificate of Incorporation; (c) any other material change in the
Company's corporate structure or business; or (d) any other action; which, in
the case of each of the matters referred to in clauses (a), (b), (c) or (d)
above, is intended, or could reasonably be expected, to impede, interfere with,
delay, postpone, discourage or materially adversely affect the contemplated
economic benefits to Parent of the Merger or the transactions contemplated by
the Merger Agreement or this Agreement. Notwithstanding anything herein to the
contrary, the foregoing provision of this Section 2 and the proxy granted
pursuant to Section 3 hereof, shall not be applicable in the event the Merger
Agreement is terminated pursuant to the provisions contained therein, and
immediately upon any such termination of the Merger Agreement, this Agreement
shall terminate and be of no further force and effect.

           3. IRREVOCABLE PROXY. EACH STOCKHOLDER HEREBY, SEVERALLY AND NOT
JOINTLY, GRANTS TO, AND APPOINTS PARENT AND THE PRESIDENT OF PARENT AND THE
TREASURER OF PARENT, IN THEIR RESPECTIVE CAPACITIES AS OFFICERS OF PARENT, AND
ANY INDIVIDUAL WHO SHALL HEREAFTER SUCCEED TO ANY SUCH OFFICE OF PARENT, AND ANY
OTHER DESIGNEE OF PARENT, EACH OF THEM INDIVIDUALLY, SUCH STOCKHOLDER'S PROXY
AND ATTORNEY-IN-FACT (WITH FULL POWER OF SUBSTITUTION) TO VOTE OR ACT BY WRITTEN
CONSENT WITH RESPECT TO SUCH STOCKHOLDER'S SUBJECT SECURITIES IN ACCORDANCE WITH
SECTION 2 HEREOF. THIS PROXY IS COUPLED WITH AN INTEREST AND SHALL BE
IRREVOCABLE, AND EACH STOCKHOLDER WILL TAKE SUCH FURTHER ACTION OR EXECUTE SUCH
OTHER INSTRUMENTS AS MAY BE NECESSARY TO EFFECTUATE THE INTENT OF THIS PROXY AND
HEREBY REVOKES ANY PROXY PREVIOUSLY GRANTED BY IT WITH RESPECT TO THE SUBJECT
SECURITIES.

           4. Covenants of the Holders. Each Holder, severally and not jointly,
hereby agrees and covenants that:

           (a) No Solicitation. Such Holder shall not, directly or indirectly,
solicit (including by way of furnishing information) or respond to any inquiries
or the making of any proposal by any person or entity (other than Parent or any
Affiliate of Parent) with respect to the Company that constitutes or could
reasonably be expected to lead to an Alternative Transaction. Such Holder will
notify Parent immediately upon becoming aware that any Person has made any
proposal, offer, inquiry, or contact with respect to any Alternative
Transaction, which notice shall include the identities of all relevant parties
and the content of such communication.


                                      -3-
<PAGE>   4
Such Holder will immediately cease and cause to be terminated any existing
activities, discussions or negotiations with any parties conducted heretofore
with respect to any of the foregoing. Notwithstanding the foregoing provisions
of this Section 4(a), such Holder may hold or continue discussions with the
Company with respect to an investment in a private placement of up to $10
million of subordinated debt or equity by the Company (which is an alternative
in the event the Merger is not consummated), provided that such Holder shall not
enter into any understanding, commitment or transaction with respect thereto
unless the Merger Agreement is terminated in accordance with Section 11.1
thereof.

           (b) Restriction on Transfer, Proxies and Noninterference. Such Holder
shall not, directly or indirectly: (i) except pursuant to the terms of the
Merger Agreement, offer for sale, sell, transfer, tender, pledge, encumber,
assign or otherwise dispose of, or enter into any contract, option or other
arrangement or understanding with respect to or consent to the offer for sale,
sale, transfer, tender, pledge, encumbrance, assignment or other disposition of,
any or all of such Holder's Subject Securities; (ii) except as contemplated
hereby, grant any proxies or powers of attorney, deposit any such Subject
Securities into a voting trust or enter into a voting agreement with respect to
any of such Holder's Subject Securities; or (iii) take any action that would
make any representation or warranty contained herein untrue or incorrect or have
the effect of preventing or disabling such Holder from performing its
obligations under this Agreement.

           (c) Tax Representations. Each Holder covenants that, on or
immediately prior to the Effective Date, it will execute and deliver to each of
Parent and the Company a letter in substantially the form of Exhibit A attached
hereto. Each Holder acknowledges that the representations made in such letter
may be relied upon by counsel in opining that the Merger constitutes a
reorganization within the meaning of Section 368(a) of the Internal Revenue Code
of 1986, as amended.

           5. Fiduciary Duties. Notwithstanding anything in this Agreement to
the contrary, the covenants and agreements set forth herein shall not prevent
any of the Holders or Holders' designees serving on the Company's Board of
Directors from taking any action required by applicable fiduciary duties (which,
if contrary to any covenant or agreement set forth herein, shall be confirmed by
written opinion of counsel) while acting in Holder's or designee's capacity as a
director of the Company.

           6. Indemnification.

           (a) Agreement to Indemnify. Each Holder (each in its capacity as
indemnifying party, an "Indemnifying Party") severally and not jointly and
severally agrees to indemnify and hold harmless each of the Buying Parties and
their respective Affiliates (each in its capacity as indemnified party, an
"Indemnitee") from, against and in respect of any and all Losses arising from or
related to any breach of or inaccuracy (or any allegation by any third party of
facts which, if true as alleged, would constitute such a breach or inaccuracy)
in any


                                      -4-
<PAGE>   5
representation or warranty, contained in Section 1 of this Agreement.

           (b) Monetary Limitation on Indemnification. The aggregate liability
of the Holders for indemnification under this Agreement shall not, when taken
together with all liabilities for Losses pursuant to Section 9.1.1 of the Merger
Agreement in any event exceed an amount equal to 10% of the total number of
Parent Shares issued in connection with the Merger.

           (c) Time Limitation on Indemnification. Claims for indemnification
for Losses shall be made on or prior to the Release Date. If written notice of a
claim has been given to any Indemnifying Party prior to the Release Date, such
claim shall survive as to such claim until such claim has been finally resolved.

           (d) Matters Involving Third Parties. Promptly after the receipt by
any Indemnitee of notice of the commencement of any action against such
Indemnitee by a third party, such Indemnitee shall, if a claim with respect
thereto is or may be made against any Indemnifying Party, use reasonable efforts
to give the Indemnifying Parties written notice thereof. The failure to give
such notice shall not relieve any Indemnifying Party from any obligation
hereunder except where, and then solely to the extent that, such failure
actually and materially prejudices the rights of such Indemnifying Party. Such
Indemnifying Party shall have the right to defend such claim, at such
Indemnifying Party's expense and with counsel of its choice reasonably
satisfactory to the Indemnitee, provided that (a) the Indemnifying Party so
notifies the Indemnitee within 30 days after receipt of such notice, (b) the
claim involves only money damages and does not seek injunctive or other
equitable relief, (c) settlement of, or an adverse judgment with respect to,
such claim is not, in the good faith judgment of the Indemnitee, reasonably
likely to establish a precedent adverse to the continuing business interests of
the Indemnitee, and (d) the Indemnifying Party conducts the defense of such
claim actively and diligently. So long as the Indemnifying Party is conducting
the defense of such claim as provided in the previous sentence, the Indemnitee
may retain separate co-counsel at its sole cost and expense and may participate
in defense of such claim, and neither the Indemnifying Party nor the Indemnitee
will consent to the entry of any judgment or enter into any settlement with
respect to such claim without the prior written consent of the other. In the
event the Indemnifying Party does not or ceases to conduct defense of such claim
as so provided, (x) the Indemnitee may defend against, such claim in any manner
it may reasonably deem to be appropriate, (y) the Indemnifying Party will
reimburse the Indemnitee promptly and periodically for the costs of defending
against such claim, including attorneys' fees and expenses, and (z) the
Indemnifying Party will remain responsible for any Losses the Indemnitee may
suffer as a result of such claim to the full extent provided in this Agreement.

           7.     Assignment; Benefits.  This Agreement shall be binding
upon, and shall inure to the benefit of, the Holders, Parent and their
respective successors and permitted assigns.

           8.     Notices.  Any notices or other communications required or
permitted

Ladies and Gentlemen:

      We are providing this letter to you pursuant to Section 4(c) of the
Stockholders Agreement dated as of ________, 1997 between the undersigned and
Parent (the "Stockholders Agreement"). Capitalized terms used herein and not
defined have the meanings assigned to them in the Stockholders Agreement.

      We hereby represent that, as of the Effective Date, we have no present
plan or intention to engage in any sale, exchange, transfer, distribution, gift,
pledge, disposition or short sale of Parent Shares received in the Merger (or
any other transaction which would result in a reduction in the risk of ownership
of Parent Shares received in the Merger).

      We are not aware of or participating in any plan on the part of Company
shareholders to transfer (i) Company Shares in contemplation of the Merger or
(ii) Parent Shares received in the Merger.

      We agree to report the Merger on applicable United States federal and
state income tax returns as a "reorganization" within the meaning of Section 368
of the Internal Revenue Code of 1986, as amended.

      Immediately prior to the Effective Date, we own, of record and
beneficially, [insert number] shares of Company Common Stock (the "Company
Shares"). The Company Shares were not acquired in contemplation of the Merger,
have been held by us at all times since [insert date of Merger Agreement], and
are not subject to any transaction which would result in a reduction in the risk
of ownership of such Company Shares.

      Each of Testa, Hurwitz & Thibeault, counsel to the Company, and Ropes &
Gray, counsel to Parent, may rely on these representations in rendering their
opinions to Company and Parent to the effect that the Merger will constitute a
reorganization within the meaning of Section 368(a) of the Internal Revenue
Code, and Company and Parent may rely on these representations in making any
representation to each such counsel for the purpose of such counsel rendering
its opinion.

               PICTURETEL CORPORATION TO PURCHASE MULTILINK, INC.

   GLOBAL VIDEOCONFERENCING LEADER WILL ACQUIRE LEADING MULTIMEDIA TECHNOLOGY
              INNOVATOR IN DEAL VALUED AT APPROXIMATELY $40 MILLION


ANDOVER, Mass. -- APRIL 15, 1997 -- PictureTel Corporation (NASDAQ: PCTL), the
global videoconferencing company, today announced that it has signed a
definitive agreement to acquire MultiLink, Inc., in a move that will expand
PictureTel's multimedia conferencing capabilities.

      MultiLink, Inc., which is based in Andover, Mass., near PictureTel's world
headquarters, enjoys a leading market share for the supply of multipoint
audioconferencing systems.

      The major reasons that PictureTel gave for making the acquisition are to
obtain technology that will enable it to accelerate its entry into the
intranet/Internet/LAN network space and to create the next generation multimedia
bridging products that mix audio, data and video with new levels of reliability,
ease-of-use and low cost. PictureTel expects to merge its IP technology with
MultiLink's technology to produce the next generation of client/server products.
In addition, PictureTel cited the importance of acquiring and expanding the
highly profitable audio bridging business in which MultiLink now enjoys the
leading market share. Because MultiLink's audio market is mainly U.S.-based,
PictureTel expects to increase this business by aggressively marketing products
through its industry-leading global distribution channels.

PICTURETEL TO ACQUIRE MULTILINK, P. 2

            "MultiLink has a strong record of delivering reliable products to
the market and they fit in well with PictureTel's strategy to be a leading
supplier of high-quality, integrated global videoconferencing systems targeted
for both the business-to-business and business- to-consumer markets," said Bill
Avery, vice president of PictureTel's Network Systems Division. The acquisition
of MultiLink provides us with access to an extremely affordable next-generation
multimedia architecture that will fill out our product line and enable new
market development. This acquisition enhances PictureTel's position as the
leader in multimedia collaboration. We believe this move will enable us to meet
customers ever-expanding demands for the most reliable, easy to use conferencing
systems and solutions.

            "In addition, the expected proliferation of clients in the H.323
conferencing space will create significantly increased demand for the networking
capabilities that PictureTel will be able to provide," said Avery.

            Under the terms of the agreement each share of MultiLink common
stock will be exchanged for 0.56 of a share of PictureTel common stock.
Outstanding options to purchase MultiLink stock will be converted at the
exchange ratio into PictureTel options. Based on the closing price of PictureTel
stock on April 15, 1997 the deal is valued at approximately $40 million.
MultiLink shareholders will own approximately 10 percent and PictureTel
shareholders will own approximately 90 percent of the combined company's shares.

            The transaction is expected to be a tax free exchange and accounted
for as a pooling of interest. PictureTel believes the transaction will be
dilutive to its earnings in 1997 as a result of one-time expenses incurred
related to the transaction but expects that the transaction will enhance
PictureTel's profit and loss statement beginning in 1998. Completion of the
transaction is conditional upon approval
