      STOCKHOLDERS PROXY AGREEMENT (this "Agreement"), dated as of June 4,
 1998, among WAXS INC., a Delaware corporation ("Parent"), and each other
 person and entity listed on the signature pages hereof (each, a
 "Stockholder"). 
  
                            W I T N E S S E T H: 
  
      WHEREAS, as of the date hereof each Stockholder owns (either
 beneficially or of record) the number of shares of common stock, par value
 $0.01 per share ("Company Common Stock"), of Telco Systems, Inc., a
 Delaware corporation (the "Company"), set forth opposite such Stockholder's
 name on Exhibit A hereto (all such shares of Company Capital Stock owned by
 the Stockholders and any shares of Company Capital Stock hereafter acquired
 by the Stockholders prior to the termination of this Agreement being
 referred to herein as the "Shares"); 
  
      WHEREAS, (i) Kopp Investment Advisors, Inc. ("Kopp") has "investment
 power" (as defined in Rule 13d-3 under the Securities Exchange Act of 1934,
 as amended ("Rule 13d-3")) with respect to 3,614,569 Shares owned by
 clients who have the right to terminate their advisory agreements with Kopp
 ("Client Shares"), and (ii) Kopp has "voting power" (as defined in Rule
 13d-3) with respect to 415,600 Client Shares ("Client Voting Shares") (the
 Client Shares that are not Client Voting Shares are referred to herein as
 "Client Advisory Shares"); 
  
      WHEREAS, Parent and the Company, among others, propose to enter into
 an Agreement and Plan of Merger and Reorganization, dated as of the date
 hereof (as the same may be amended from time to time, the "Merger
 Agreement"; capitalized terms herein not otherwise defined herein shall
 have the meanings ascribed thereto in the Merger Agreement), which
 provides, upon the terms and subject to the conditions thereof, for the
 merger of a subsidiary of Parent with and into the Company (the "Merger");
 and 
  
      WHEREAS, as a condition to the willingness of Parent to enter into the
 Merger Agreement, Parent has requested that each Stockholder agree, and, in
 order to induce Parent to enter into the Merger Agreement, each Stockholder
 has agreed, to grant Parent proxies to vote such Stockholder's Shares; 
  
      NOW, THEREFORE, in consideration of the premises and of the mutual
 agreements and covenants set forth herein and in the Merger Agreement, the
 parties hereto agree as follows: 
  
  
                                 ARTICLE I 
                       TRANSFER AND VOTING OF SHARES 
  
      SECTION 1.01.  TRANSFER OF SHARES.  During the term of this Agreement,
 and except as otherwise provided herein, each Stockholder (other than Kopp
 with respect to the Client Shares) shall not (a) sell, pledge or otherwise
 dispose of any of its Shares if such transaction would result in the
 Stockholder no longer having the power to vote or cause to be voted the
 Shares, (b) deposit its Shares into a voting trust or enter into a voting
 agreement or arrangement with respect to such Shares or grant any proxy
 with respect thereto or (c) enter into any contract, option or other
 arrangement or undertaking with respect to the direct or indirect
 acquisition or sale, assignment, transfer or other disposition of any of
 the Company Capital Stock if such transaction would result in the
 Stockholder no longer having the power to vote or cause to be voted the
 Shares. 
  
      SECTION 1.02.  VOTING OF SHARES; FURTHER ASSURANCES.  (a) Each
 Stockholder, by this Agreement, with respect to those Shares that it owns
 of record, does hereby constitute and appoint Parent, or any nominee of
 Parent, with full power of substitution, during and for the term of this
 Agreement, as its true and lawful attorney and proxy, for and in its name,
 place and stead, to vote each of such Shares as its proxy, at every annual,
 special or adjourned meeting of the stockholders of the Company (including
 the right to sign its name (as stockholder) to any consent, certificate or
 other document relating to the Company that the law of the State of
 Delaware may permit or require) (i) in favor of the adoption of the Merger
 Agreement and approval of the Merger and the other transactions
 contemplated by the Merger Agreement, (ii) against any proposal for any
 recapitalization, merger, sale of assets or other business combination
 between the Company and any person or entity (other than the Merger) or any
 other action or agreement that would result in a breach of any covenant,
 representation or warranty or any other obligation or agreement of the
 Company under the Merger Agreement or which could result in any of the
 conditions to the Company's obligations under the Merger Agreement not
 being fulfilled, and (iii) in favor of any other matter relating to
 consummation of the transactions contemplated by the Merger Agreement. 
 Each Stockholder further agrees to cause the Shares owned by it
 beneficially to be voted in accordance with the foregoing.  Each
 Stockholder acknowledges receipt and review of a copy of the Merger
 Agreement.  Notwithstanding anything in this Section 1.02(a) to the
 contrary, the Client Advisory Shares shall not be subject to this Section
 1.02(a) and the Client Voting Shares shall cease to be subject to this
 Section 1.02(a) if and when the owner of such Client Voting Shares
 terminates its advisory agreement with Kopp. 
  
           (b)  Each Stockholder shall perform such further acts and execute
 such further documents and instruments as may reasonably be required to
 vest in Parent the power to carry out the provisions of this Agreement. 
  
           (c)  Nothing contained in this Agreement shall be deemed to
 restrict a Stockholder who is also a director of the Company from taking
 actions in his capacity as a director as may be permitted under the Merger
 Agreement. 
       
      SECTION 1.03.  TERM OF AGREEMENT.  This Agreement shall be effective
 as of the date hereof and shall expire on the earlier of (a) the Effective
 Time and (b) the date of the termination of the Merger Agreement pursuant
 to its terms.

                                STOCKHOLDERS 
  
      Each Stockholder, severally and not jointly, hereby represents and
 warrants to Parent as follows: 
  
      SECTION 2.01.  DUE ORGANIZATION, ETC.  Such Stockholder (if it is a
 corporation, partnership or other legal entity) is duly organized and
 validly existing under the laws of the jurisdiction of its organization. 
 Such Stockholder has full power and authority (corporate or otherwise) to
 execute and deliver this Agreement and to consummate the transactions
 contemplated hereby.  The execution and delivery of this Agreement and the
 consummation of the transactions contemplated hereby have been duly
 authorized by all necessary action (corporate or otherwise) on the part of
 such Stockholder.  This Agreement has been duly executed and delivered by
 or on behalf of such Stockholder and, assuming its due authorization,
 execution and delivery by Parent, constitutes a legal, valid and binding
 obligation of such Stockholder, enforceable against such Stockholder in
 accordance with its terms, subject to the effect of any applicable
 bankruptcy, reorganization, insolvency, moratorium or similar laws
 affecting creditors' rights generally and subject, as to enforceability, to
 the effect of general principles of equity (regardless of whether such
 enforceability is considered in a proceeding in equity or at law). 
  
      SECTION 2.02.  NO CONFLICTS; REQUIRED FILINGS AND CONSENTS.  (a) The
 execution and delivery of this Agreement by such Stockholder do not, and
 the performance of this Agreement by such Stockholder will not, (i)
 conflict with or violate the Certificate of Incorporation or By-Laws or
 similar organizational documents of such Stockholder (in the case of a
 Stockholder that is a corporation, partnership or other legal entity), (ii)
 conflict with or violate any law, rule, regulation, order, judgment or
 decree applicable to such Stockholder or by which it or any of its
 properties is bound or affected, or (iii) result in any breach of or

 would become a default) under, or give to others any rights of termination,
 amendment, acceleration or cancellation of, or result in the creation of a
 lien or encumbrance on any of the property or assets of such Stockholder or
 (if such Stockholder is a corporation) any of its subsidiaries pursuant to,
 any note, bond, mortgage, indenture, contract, agreement, lease, license,
 permit, franchise or other instrument or obligation to which such
 Stockholder is a party or by which such Stockholder or any of its
 properties is bound or affected, except for any such breaches, defaults or
 other occurrences that would not cause or create a material risk of non-
 performance or delayed performance by such Stockholder of its obligations
 under this Agreement. 
  
           (b)  The execution and delivery of this Agreement by such
 Stockholder do not, and the performance of this Agreement by such
 Stockholder will not, require any consent, approval, authorization or
 permit of, or filing with or notification to, any governmental or
 regulatory authority, domestic or foreign, except (i) for applicable
 requirements, if any, of the Exchange Act, and the HSR Act and (ii) where
 the failure to obtain such consents, approvals, authorizations or permits,
 or to make such filings or notifications, would not prevent or delay the
 performance by such Stockholder of its obligations under this Agreement. 
  
      SECTION 2.03.  TITLE TO SHARES.  Other than with respect to Kopp to
 the extent described in its Schedule 13D dated May 13, 1998 and in Exhibit
 A hereto, such Stockholder is the record or beneficial owner of its Shares
 free and clear of any proxy or voting restriction other than pursuant to
 this Agreement.

 execution and delivery of this Agreement by Parent do not, and the
 performance of this Agreement by Parent will not, (i) conflict with or

 default) under, or give to others any rights of termination, amendment,
 acceleration or cancellation of, or result in the creation of a lien or
 encumbrance on any of the property or assets of Parent pursuant to, any
 note, bond, mortgage, indenture, contract, agreement, lease, license,
 permit, franchise or other instrument or obligation to which Parent is a
 party or by which it or any of its properties is bound or affected, except
