                                  PART II

                          INFORMATION REQUIRED IN
                         THE REGISTRATION STATEMENT
                                           
Item 3.  Incorporation of Documents by Reference.

         The following documents, which have heretofore been filed by the
registrant with the Securities and Exchange Commission, are incorporated by
reference herein and shall be deemed to be part hereof:

         (i)  Annual Report of Teltone Corporation on Form 10-KSB for the year
              ended June 30, 1996.

         (ii) Proxy Statement of Teltone Corporation dated September 30, 1996.

         (iii)     Quarterly Report of Teltone Corporation on Form 10-QSB for
              the quarter ended September 30, 1996.

         (iv) Quarterly Report of Teltone Corporation on Form 10-QSB for the
              quarter ended December 31, 1996.

    All documents subsequently filed by the registrant or the plan pursuant to
Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934 prior
to the filing of a post-effective amendment which indicates that all securities
offered have been sold or which deregisters all securities then remaining unsold
shall be deemed to be incorporated herein by reference and shall be deemed a
part hereof from the date of filing of such documents.

Item 4.  Description of Securities.

    Not applicable.

Item 5.  Interests of Named Experts and Counsel.

    Legal matters in connection with the securities offered hereby were passed
upon by Preston Gates & Ellis LLP, Seattle, Washington.  Lawyers in the firm
participating in the matter beneficially own, in the aggregate and individually,
none of the Company's common stock.

Item 6.  Indemnification of Directors and Officers.

    Article IX of the Articles of Incorporation of the Company require the
Company to indemnify any present or former officer or director to the fullest
extent not prohibited by the Washington Business Corporation Act. 
Chapter 23B.8.510 and .570 of the Washington Business Corporation Act authorizes
a corporation to indemnify its officers and directors in terms sufficiently
broad to permit such indemnification under certain circumstances for liabilities
(including reimbursement for expenses incurred) arising under the Securities Act
of 1933.

    Not applicable.

Item 8.  Exhibits.

    See Exhibit Index.

Item 9.  Undertakings.

A.  RULE 415 OFFERING.

    The undersigned registrant hereby undertakes:

    1.   To file, during any period in which offers or sales are being made, a
         post-effective amendment to this registration statement:
    
         (i)  To include any prospectus required by section 10(a)(3) of the
              Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after
              the effective date of the registration statement (or the most
              recent post-effective amendment thereof) which, individually or
              in the aggregate, represent a fundamental change in the
              information set forth in the registration statement;

         (iii)     To include any material information with respect to the plan
              of distribution not previously disclosed in the registration
              statement or any material change to such information in the
              registration statement:

                   PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii)
                   do not apply if the registration statement is on Form S-3 or
                   Form S-8, and the information required to be included in a
                   post-effective amendment by those paragraphs is contained in
                   periodic reports filed by the registrant pursuant to
                   section 13 or section 15(d) of the Securities Exchange Act
                   of 1934 that are incorporated by reference in the
                   registration statement.

    2.   That, for the purpose of determining any liability under the
         Securities Act of 1933, each such post-effective amendment shall be
         deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time
         shall be deemed to be the initial bona fide offering thereof.

                                   -3-
<PAGE>

    3.   To remove from registration by means of a post-effective amendment any
         of the securities being registered which remain unsold at the
         termination of the offering.

B.  FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE.

    The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d)of the 
Securities Exchange Act of 1934) that is incorporated by reference in the 
registration statement shall be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.

C.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions of the registrant's certificate of
incorporation or by-laws or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.

certifies that it has reasonable grounds to believe that it meets all of the
requirements for filing on Form S-8 and has duly caused this  Registration
Statement to be signed on its behalf by the undersigned, thereunto duly

Item 9.  Undertakings.

A.  RULE 415 OFFERING.

    The undersigned registrant hereby undertakes:

    1.   To file, during any period in which offers or sales are being made, a
         post-effective amendment to this registration statement:
    
         (i)  To include any prospectus required by section 10(a)(3) of the
              Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after
              the effective date of the registration statement (or the most
              recent post-effective amendment thereof) which, individually or
              in the aggregate, represent a fundamental change in the
              information set forth in the registration statement;

         (iii)     To include any material information with respect to the plan
              of distribution not previously disclosed in the registration
              statement or any material change to such information in the
              registration statement:

                   PROVIDED, HOWEVER, that paragraphs (a)(1)(i) and (a)(1)(ii)
                   do not apply if the registration statement is on Form S-3 or
                   Form S-8, and the information required to be included in a
                   post-effective amendment by those paragraphs is contained in
                   periodic reports filed by the registrant pursuant to
                   section 13 or section 15(d) of the Securities Exchange Act
                   of 1934 that are incorporated by reference in the
                   registration statement.

    2.   That, for the purpose of determining any liability under the
         Securities Act of 1933, each such post-effective amendment shall be
         deemed to be a new registration statement relating to the securities
         offered therein, and the offering of such securities at that time
         shall be deemed to be the initial bona fide offering thereof.

                                   -3-
3.   To remove from registration by means of a post-effective amendment any
         of the securities being registered which remain unsold at the
         termination of the offering.

B.  FILINGS INCORPORATING SUBSEQUENT EXCHANGE ACT DOCUMENTS BY REFERENCE.

    The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d)of the 
Securities Exchange Act of 1934) that is incorporated by reference in the 
registration statement shall be deemed to be a new registration statement 
relating to the securities offered therein, and the offering of such 
securities at that time shall be deemed to be the initial bona fide offering 
thereof.

C.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions of the registrant's certificate of
incorporation or by-laws or otherwise, the registrant has been advised that in
the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Securities Act of 1933 and is,
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by the registrant of expenses incurred
or paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act of 1933 and will be governed by the
final adjudication of such issue.

                                   -4-
