certain Series A Preferred Stock Purchase Agreement of even date herewith

         NOW, THEREFORE, in consideration of the foregoing premises and
certain other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the Parties agree as follows:

         1.       AGREEMENT TO VOTE. Each Investor, as a holder of Preferred
Stock, hereby agrees on behalf of itself and any transferee or assignee of
any such shares of the Preferred Stock, to hold all of the shares of

issued with respect to, upon conversion of, or in exchange or substitution of
the Preferred Stock, and any other voting securities of the Company
subsequently acquired by such Investor) (hereinafter collectively referred to
as the "Investor Shares") subject to, and to vote the Investor Shares at a
regular or special meeting of stockholders (or by written consent) in
accordance with, the provisions of this Agreement. Each Founder, as a holder
of Common Stock of the Company, hereby agrees on behalf of itself and any
transferee or assignee of any such shares of Common Stock, to hold all of
such shares of Common Stock and any other voting securities of the Company
acquired by such Founder in the future (and any securities of the Company
issued with respect to, upon conversion of, or in exchange or substitution
for such securities) (the "Founder Shares") subject to, and to vote the
Founder Shares at a regular or special meeting of stockholders (or by written
consent) in accordance with, the provisions of this Agreement.

         2.       BOARD SIZE. The holders of Investor Shares and Founder

by written consent) such shares that they own (or as to which they have
voting power) to ensure that the size of the Board shall be set and remain at
four (4) directors; provided, however, that such Board size may be
subsequently increased or decreased pursuant to an amendment of this
Agreement in accordance with Section 15 hereof.

         3.       ELECTION OF DIRECTORS. In any election of directors of the
Company, the Parties shall each vote at any regular or special meeting of
stockholders (or by written consent) such number of shares of voting capital
stock then owned by them (or as to which they then have voting power) as may
be necessary to elect the following individuals to the Board:

                  (a)      the Founders; and

                  (b)      TeleVideo, Inc.

         4.       REMOVAL. Any director of the Company may be removed from
the Board in the manner allowed by law and the Company's Amended and Restated
Certificate of Incorporation and Bylaws, but with respect to a director
designated pursuant to Sections 3(a) and (b) above, only upon the vote or
written consent of the stockholders entitled to designate such director.

         5.       LEGEND ON SHARE CERTIFICATES. Each certificate representing
any Investor Shares or Founder Shares shall be endorsed by the Company with a
legend reading substantially as follows:

         "The Shares evidenced hereby are subject to a Voting Agreement (a
         copy of which may be obtained upon written request from the issuer),
         and by accepting any interest in such shares the person accepting
         such interest shall be deemed to agree to and shall become bound by
         all the provisions of said Voting Agreement."

         6.       COVENANTS OF THE COMPANY. The Company agrees to use its
best efforts to ensure that the rights granted hereunder are effective and
that the Parties hereto enjoy the benefits thereof. Such actions include,
without limitation, the use of the Company's best efforts to cause the
nomination and election of the directors as provided above. The Company will
not, by any voluntary action, avoid or seek to avoid the observance or
performance of any of the terms to be performed hereunder by the Company, but
will at all times in good faith assist in the carrying out of all of the
provisions of this Agreement and in the taking of all such actions as may be
necessary, appropriate or reasonably requested by the holders of a majority
of the outstanding voting securities held by the Parties hereto assuming
conversion of all outstanding securities in order to protect the rights of
the Parties hereunder against impairment.

         7.       NO LIABILITY FOR ELECTION OF RECOMMENDED DIRECTORS. Neither
the Company, the Founders, the Investors, nor any officer, director,
stockholder, partner, employee or agent of such Party, makes any
representation or warranty as to the fitness or competence of the nominee of

execution of this Agreement or by the act of such Party in voting for such
nominee pursuant to this Agreement.

         8.       GRANT OF PROXY. Should the provisions of this Agreement be
construed to constitute the granting of proxies, such proxies shall be deemed
coupled with an interest and are irrevocable for the term of this Agreement.

         9.       SPECIFIC ENFORCEMENT. It is agreed and understood that
monetary damages would not adequately compensate an injured Party for the
breach of this Agreement by any Party, that this Agreement shall be
specifically enforceable, and that any breach or threatened breach of this
Agreement shall be the proper subject of a temporary or permanent injunction
or restraining order. Further, each Party hereto waives any claim or defense
that there is an adequate remedy at law for such breach or threatened breach.

cause the certificates evidencing the shares of Common Stock and Preferred
Stock to bear the legend required by Section 5 herein and/or failure of the
Company to supply, free of charge, a copy of this Agreement as provided under
this Section 10 shall not affect the validity or enforcement of this
Agreement.

this Agreement are for convenience only and do not in any way limit or
amplify the terms and provisions hereof.

of the Company pursuant to its stock option, stock purchase or similar plan
or a SEC Rule 145 transaction), (b) the acquisition of the Company by another
entity by means of any transaction or series of related transactions

that results in the transfer of fifty percent (50%) or more of the

particular instance and either retroactively or prospectively) only with the
written consent of (i) the Company, (ii) the holders of a majority of the

the legend set forth in Section 5.

         17.      SEVERABILITY. Whenever possible, each provision of this
Agreement shall be interpreted in such manner as to be effective and valid
under applicable law, but if any provision of this Agreement shall be held to
be prohibited by or invalid under applicable law, such provision shall be
ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of
this Agreement.

         18.      BINDING EFFECT. In addition to any restriction or transfer
that may be imposed by any other agreement by which any Party hereto may be
bound, this Agreement shall be binding upon the Parties, their respective
heirs, successors and assigns and to such additional individuals or entities
that may become stockholders of the Company and that desire to become Parties
hereto; provided that for any such transfer to be deemed effective, the
transferee shall have executed and delivered an Adoption Agreement
substantially in the form attached hereto as EXHIBIT A. Upon the execution

to the Company, such transferee shall be deemed to be a Party hereto as if
such transferee's signature appeared on the signature pages hereto. By their
execution hereof of any Adoption Agreement, each of the Parties hereto
appoints the Company as its attorney-in-fact for the purpose of executing any
Adoption Agreement which may be required to be delivered hereunder.

construed in accordance with the laws of the State of California, without
regard to conflicts of law principles thereof.

         20.      ENTIRE AGREEMENT. This Agreement is intended to be the sole
agreement of the Parties as it relates to this subject matter and does hereby
supersede all other agreements of the Parties relating to the subject matter
hereof.

         21.      COUNTERPARTS. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one and the same instrument.

         22.      ARBITRATION. Any controversy between the Parties hereto
involving any claim arising out of or relating to this Agreement, will be
submitted to and be settled by final and binding arbitration in Palo Alto,
California, in accordance with the then current Commercial Arbitration Rules
of the American Arbitration Association (the "AAA"), and judgment upon the
award rendered by the arbitrator may be entered in any court having
jurisdiction thereof. Such arbitration shall be conducted by one (1)
arbitrator mutually agreeable to the Company, a majority-in-interest of the
Founders and a majority-in-interest of the Investors, or failing such
agreement, an arbitrator experienced in similarly-sized companies appointed
by the AAA. There shall be limited discovery prior to the arbitration hearing
as follows: (a) exchange of witness lists and copies of documentary evidence
and documents relating to or arising out of the issues to be

any Subsidiary to, form or acquire any corporation or limited liability company which would thereby become a Subsidiary.

    (f)  Permitted Acquisitions.  Section 6.10(l) of the Credit Agreement is amended to provide as follows:

    Section
6.10(l)  Purchases of the assets of Persons engaged in the communications industry, provided that the Majority
Banks have consented thereto in writing not less than 10 days prior to the consummation thereof.

    (h)  New Events of Default.  The following new Sections 7.1(o) and (p) of the Credit Agreement are added
immediately following Section 7.1(n) of the Credit Agreement:

    7.1(o)  Any
Security Document shall, at any time, cease to be in full force and effect or shall be judicially declared null and void, or the validity or
the enforceability thereof shall be contested by the Borrower or any Guarantor.

    7.1(p)  Any
"Event of Default" shall occur under any Security Document.

    Section
3.  Waiver.  The Borrower has informed the Banks as follows:

    (a) that
it was not in compliance with its covenant under Section 6.10(k)(ii) of the Credit Agreement as of October 31, 1999, in that the aggregate
outstanding principal of loans and advances as of such date from Norstan Communications, Inc. to Connaissance was in excess of $4,000,000;

    (b) that
it was not in compliance with its covenant under Section 6.10(n) of the Credit Agreement as of October 31, 1999, in that the aggregate
outstanding principal of loans to its officers and employees as of such date exceeded $500,000;

    (c) that
it was not in compliance with its covenant under Section 6.16 of the Credit Agreement for the period ended October 31, 1999, in that its actual
EBITDA for the period of four consecutive fiscal quarters ended on that date was less than $26,000,000;

Each
such instance of noncompliance constitutes an Event of Default under the Credit Agreement. Upon satisfaction of the conditions set forth in Section 5 of this Amendment, the Banks hereby
waive the Events of Default under the Credit Agreement described in the preceding sentence. This waiver is limited to the express terms hereof and shall not extend to any other Default, Event of
Default or any other period. This waiver shall not be and shall not be deemed to be a course of dealing upon which the Borrower may rely with respect to any other Default, Event of Default or request
for a waiver and the Borrower hereby expressly waives any such claim.

    Section

    (b) This
Amendment may be executed in as many counterparts as may be deemed necessary or convenient, and by the different parties hereto on separate counterparts, each
