                 MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

       TO THE STOCKHOLDERS OF WESTELL TECHNOLOGIES, INC. AND TELTREND INC.

         The boards of directors of Westell Technologies, Inc. and Teltrend Inc.
have unanimously approved a merger of Teltrend with a wholly-owned subsidiary of
Westell,  pursuant to which Teltrend  would become a wholly-owned  subsidiary of
Westell.

         Upon completion of the merger,  Teltrend  stockholders will receive 3.3
shares of Westell  Class A Common  Stock in exchange  for each share of Teltrend
common stock they own, subject to provisions  regarding  payment of cash in lieu
of fractional  shares.  The exchange ratio is fixed and will not change based on
any changes in the value of Westell's Class A Common Stock or Teltrend's  common
stock.  Westell's  stockholders  will continue to own their  existing  shares of
Westell  Class A Common Stock and Class B Common  Stock.  After the merger,  the
Teltrend stockholders will hold approximately 34% of Westell's outstanding Class
A Common Stock and Class B Common Stock,  considered together,  or approximately
17% of  the  total  voting  power  of  Westell.  Assuming  the  exercise  of all
outstanding  options  and  warrants  to  purchase  Class A Common  Stock and the
conversion  of Westell's  outstanding  convertible  debentures  at their current
conversion  price,  these  percentages  would  be  approximately  29%  and  16%,
respectively.

         The merger  requires the  stockholders  of Teltrend to adopt the merger
agreement and the  stockholders  of Westell to approve the stock issuance in the
merger and a related amendment to Westell's Amended and Restated  Certificate of
Incorporation  to increase the number of shares of  authorized  Westell  Class A
Common Stock. We have scheduled  meetings for our  stockholders to vote on these
matters.

         Regardless  of the  number of  shares  you own or  whether  you plan to
attend a meeting,  it is important that your shares be represented and voted. We
ask that you take the time to vote by completing  and mailing the enclosed proxy
card promptly. Voting instructions are inside.

         The dates, times and places of the meetings are as follows:

                    NOTICE OF SPECIAL MEETING OF STOCKHOLDERS

TO THE STOCKHOLDERS OF
WESTELL TECHNOLOGIES, INC.:

         Westell  Technologies,   Inc.  will  hold  a  special  meeting  of  its
stockholders  on March  __,  2000,  at 10:00  a.m.,  local  time,  at  Westell's
corporate headquarters, 750 North Commons Drive, Aurora, Illinois 60504, for the
following purposes:

         (1) To  consider  and act upon a proposal  to approve  the  issuance of
shares of Westell's  Class A Common Stock,  in accordance with the agreement and
plan of merger dated December 13, 1999 among Westell, Theta Acquisition Corp., a
wholly owned  subsidiary  of Westell,  and  Teltrend  Inc. as we describe in the
attached joint proxy statement/prospectus;

         (2) To consider and act upon a proposal to amend Westell's  Amended and
Restated  Certificate  of  Incorporation  to  increase  to 85 million  from 65.5
million the total number of shares of Westell  Class A Common Stock that Westell
is  authorized  to issue,  effective  as of the  effective  time of the proposed
merger; and

         (3) To transact  such other  business as may  properly  come before the
meeting or any adjournments or postponements thereof.

         The close of business on ____________,  2000 is the record date for the
Westell special  meeting.  Holders of Westell's Class A Common Stock and Class B
Common Stock on the record date will be entitled to vote at the meeting.  On the
record date,  there were _____  shares of Westell  Class A Common Stock and ____
shares of Westell Class B Common Stock outstanding.  Each share of Westell Class
A Common Stock entitles its holder to one vote and each share of Westell Class B
Common Stock entitles its holder to four votes.

         Each proposal will be voted upon separately by Westell's  stockholders,
with the  holders  of  shares of Class A Common  Stock and Class B Common  Stock
voting together as a single class with respect to each proposal. The merger will
not be  completed  unless each  proposal is approved by the required  vote.  The
affirmative  vote of a majority  of the total  votes cast is required to approve
the issuance of shares of  Westell's  Class A Common Stock in the merger and the
affirmative vote of a majority of the total votes outstanding on the record date
is  required  to  approve  the  amendment  to  Westell's  Amended  and  Restated
Certificate of Incorporation.  The co-trustees of the Westell Technologies, Inc.
Voting Trust,  who  beneficially  own  approximately  80% of the voting power of
Westell,  have  agreed  to vote in favor of these  proposals  if a  majority  of
Westell's  non-affiliated,   public  stockholders  so  vote.  In  addition,  the
co-trustees  may also vote in favor of the  proposals  even if a majority of the
non-affiliated,  public stockholders reject the proposals.  The co-trustees have
indicated  their  current  intention  to  vote  as  the  majority  of  Westell's
non-affiliated,  public  stockholders  vote with respect to the  proposals.  The
voting  agreement  is  described  in more  detail in the  attached  joint  proxy
statement/prospectus.

         Westell's  Board of  Directors  believes  that the merger will  provide
significant  benefits  to  Westell's  stockholders,   customers  and  employees.
Westell's  Board of  Directors  has  unanimously  approved  the  merger  and the
proposals  to  be  presented  at  the  meeting  and   recommends   that  Westell
stockholders vote in favor of the proposals.

         PLEASE  SIGN  AND  PROMPTLY  RETURN  THE  PROXY  CARD  IN THE  ENCLOSED
ENVELOPE,  WHETHER OR NOT YOU EXPECT TO ATTEND THE WESTELL  SPECIAL  MEETING.  A
PROMPT  RESPONSE  IS  HELPFUL,  AND  YOUR  COOPERATION  WILL BE  APPRECIATED.  A
stockholder  who  executes a proxy may revoke it any time before it is exercised
by giving written notice of revocation to the corporate secretary of Westell, by
subsequently  filing  another  later-dated  proxy or by  attending  the  Westell
special meeting and voting in person.

                                 By Order of the Board of Directors,

                                 /s/ Nicholas C. Hindman, Sr.

                                    OVERVIEW

                     QUESTIONS AND ANSWERS ABOUT THE MERGER



Q:   WHEN AND WHERE ARE THE STOCKHOLDER MEETINGS?

A:   The  Westell  meeting  will  take  place on  March  __,  2000 at  Westell's
     corporate  headquarters,  750 North Commons Drive, Aurora,  Illinois 60504.
     The  Teltrend  meeting  will  take  place on March __,  2000 at  Teltrend's
     corporate headquarters, 620 Stetson Avenue, St. Charles, Illinois 60174.

Q:   WHAT DO I NEED TO DO NOW?

A:   After carefully  reading and considering the information  contained in this
     document,  please  fill out,  sign and mail your  signed  proxy card in the
     enclosed  return  envelope  as soon as  possible,  so that we may vote your
     shares at the appropriate meeting.

     In order to assure  that we obtain  your  vote,  please  give your proxy as
     instructed  on your  proxy  card even if you  currently  plan to attend the
     meeting in person.

Q:    IF  MY SHARES ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER  VOTE
      MY SHARES FOR ME?

A:    If you do not provide  your broker with  instructions  on how to vote your
      "street name" shares,  your broker cannot vote them. You should  therefore
      be sure to  provide  your  broker  with  instructions  on how to vote your
      shares.

      If you do not give  voting  instructions  to your  broker,  you  will,  in
      effect,  be voting  against the merger  unless you appear in person at the
      appropriate  meeting with a proxy from your broker authorizing you to vote
      your  "street  name"  shares,   and  vote  in  favor  of  the   applicable
      proposal(s).

Q:    CAN I CHANGE MY VOTE AFTER I HAVE MAILED MY SIGNED PROXY CARD?

A:    Yes.  You can change  your vote at any time  before your proxy is voted at
      the applicable  stockholder meeting. You can do this in one of three ways:
      (1) you can send a written  notice  stating  that you would like to revoke
      your proxy, (2) you can complete and submit a new proxy card which bears a
      later date (if you choose  either (1) or (2),  you must submit your notice
      of  revocation  or  your  new  proxy  card  to the  appropriate  corporate
      secretary),  or (3) you can attend your meeting and vote in person. Simply
      attending the meeting,  however,  will not revoke your proxy.  If you have
      instructed  a broker  to vote  your  shares,  you must  follow  directions
      received from your broker to change those instructions.

Q:    WHAT WILL TELTREND STOCKHOLDERS RECEIVE FOR THEIR TELTREND SHARES?

A:    In the merger,  Teltrend  stockholders  will receive 3.3 shares of Westell
      Class A Common Stock in exchange  for each share of Teltrend  common stock
      they hold.  This exchange ratio will not change,  even if the market price
      of Westell or Teltrend shares  increases or decreases  between now and the
      date the merger is completed.  Because the market price of Westell Class A
      Common Stock may fluctuate from day to day, Teltrend  stockholders  cannot
      be sure of the market value of the Westell  Class A Common Stock they will
      receive in the merger at the time they vote their shares.

      Westell  will not issue  fractional  shares in the  merger.  The  Teltrend
      stockholders  will receive cash in lieu of fractional  shares based on the
      average  closing  price of the Westell  Class A Common Stock during the 10
      trading days immediately preceding the merger.

Q.    WILL THE MERGER BE TAXABLE TO ME?

A.    We expect that the merger  generally will not be taxable to either Westell
      or  Teltrend  or  Teltrend's  stockholders  for U.S.  federal  income  tax
      purposes, except for cash received in lieu of any fractional shares.

Q.    WHAT RISKS SHOULD I CONSIDER?

A.    You should review "Risk  Factors"  beginning on page I-13. You should also
      review the  countervailing  factors  considered by each company's Board of
      Directors.  See "Westell's  Reasons for the Merger;  Recommendation of the
      Westell  Board"  beginning  on page II-4 and  "Teltrend's  Reasons for the
      Merger; Recommendation of the Teltrend Board" beginning on page II-6.


<PAGE>


Q.    HOW MANY CLASSES OF COMMON STOCK DOES WESTELL HAVE?

A.    Westell has two classes of common stock:  Class A Common Stock and Class B
      Common Stock. Generally, both classes vote together as a single class with
      each share of Class A Common Stock having one vote and each share of Class
      B Common Stock having four votes.  Economically,  Westell's Class A Common
      Stock and Class B Common Stock are equivalent.

Q:    WILL WESTELL STOCKHOLDERS RECEIVE ANY SHARES AS A RESULT OF THE MERGER?

A:    No.  Westell stockholders will continue to  hold the  Westell  shares they
      currently own.  After the merger, these shares will represent an ownership
      interest in the combined businesses of Westell and Teltrend.

Q:    SHOULD TELTREND STOCKHOLDERS SEND IN THEIR STOCK CERTIFICATES NOW?

A:    No.   After  we  complete  the  merger,  we  will  send  to  the T eltrend
      stockholders  written  instructions  to exchange the Teltrend common stock
      for Westell Class A Common Stock.

Q:    WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?

A:    We expect to complete the merger as soon as possible after the stockholder
      meetings,   assuming  the  stockholders  of  both  companies  approve  the
      transaction.  However, because the merger is subject to certain regulatory
      approvals and other conditions, we cannot predict the exact timing.

Q:    WHO CAN HELP ANSWER QUESTIONS?

A:    If you have more questions about the merger you should contact:

THE COMPANIES

WESTELL TECHNOLOGIES, INC.
750 N. Commons Drive
Aurora, Illinois 60504
800-323-6883

         Since 1980,  Westell has  developed  telecommunications  products  that
address the needs of  telephone  companies  to upgrade  their  existing  network
infrastructures  in order to deliver  advanced data and voice  services to their
customers. Westell designs, manufactures,  markets and services a broad range of
digital and analog  products  used by telephone  companies  to deliver  services
primarily  over  existing  copper  telephone  wires that  connect end users to a
telephone  company's  central office.  This existing  infrastructure is commonly
referred to as the local loop or the local access network.  Westell also markets
its products and services to other  telecommunications  and information  service
providers seeking direct access to end user customers.  In addition,  Conference
Plus,  Inc.,  Westell's 88% owned  subsidiary,  provides audio,  video, and data
conferencing  services.  Businesses and  individuals  use these services to hold
voice,  video or data conferences with many people at the same time.  Conference
Plus sells its  services  directly  to large  customers,  including  Fortune 100
companies, and serves customers indirectly through its private reseller program.
Westell is currently  considering a proposal to spin-off  Conference Plus in the
next 12 to 24 months.

TELTREND INC.
620 Stetson Avenue
St. Charles, Illinois 60174
630-377-1700

         Teltrend   designs,   manufactures   and   markets  a  broad  range  of
transmission  products  used by telephone  companies  to provide  voice and data
service  over  the  telephone  network.   Historically,   substantially  all  of
Teltrend's  products  have been sold  directly to the  regional  bell  operating
companies and their local  affiliates  (RBOCs) for use with the copper  wireline
that is generally used to carry voice and data across the local loop. Teltrend's
strong reliance on the RBOCs continues,  but its purchase of Teltrend Limited in
September  1997  expanded  its markets and product  lines.  With the addition of
Teltrend  Limited,   Teltrend  has  entered  the   telecommunication   signaling
interworking   market,   providing   products   that   interpret  and  translate
transmission signals to allow for interoperability  between older-generation and
next-generation   telecommunications   networks.   Teltrend  Limited  sales  are
primarily targeted in Europe.

REASONS FOR THE MERGER

         Both the Westell Board and the Teltrend Board believe that the combined
company will have the  potential  to realize  long-term  synergies  and improved
financial and operating  results.  We believe that the combined  company will be
positioned to provide leading network and  telecommunication  service  providers
world-wide  with digital  subscriber  line system and technology  solutions that
meet the standards for network level interoperability.

RECOMMENDATIONS TO STOCKHOLDERS

         Both the Westell  Board and the Teltrend  Board believe that the merger
is in the best interests of their  respective  companies'  stockholders and that
the strong  management teams from both companies will work to achieve  potential
long-term synergies and realize growth opportunities.

         TELTREND:  The Teltrend Board has  unanimously  approved the merger and
the merger agreement.  The Teltrend Board recommends that Teltrend  stockholders
vote FOR the proposal to adopt the merger agreement,  under which a wholly owned
subsidiary of Westell will be merged with Teltrend.

         WESTELL:  The Westell Board has unanimously approved the merger and the
merger  agreement.   The  Westell  Board  unanimously  recommends  that  Westell
stockholders vote FOR the proposals submitted for Westell  stockholder  approval
in connection with the merger.

THE MERGER

         The  agreement  and  plan of  merger  dated  December  13,  1999  among
Teltrend, Westell and Theta Acquisition Corp. is the legal document that governs
the merger.  The merger  agreement is attached as Appendix A to this joint proxy
statement/prospectus. We encourage you to read the merger agreement carefully.

         In the  merger,  Teltrend  will  become a  wholly-owned  subsidiary  of
Westell,  and each share of Teltrend  common  stock will be  converted  into the
right to receive 3.3 shares of Westell Class A Common  Stock.  Cash will be paid
in lieu of any  fractional  shares,  based on the average  closing  price of the
Westell  Class A Common Stock during the 10 trading days  immediately  preceding
the merger.

         Each  option to  purchase  shares of  Teltrend  common  stock  which is
unexpired  and  unexercised  as of the  effective  time  will  be  automatically
converted  into an option to  purchase  a number  of shares of  Westell  Class A
Common Stock equal to the number of shares of Teltrend  common stock  subject to
such option  multiplied  by the  exchange  ratio at an exercise  price per share
equal to the exercise price in effect under such option immediately prior to the
effective time divided by the exchange  ratio.  See "Treatment of Teltrend Stock
Options" on page IV-2.

COMPARATIVE PER SHARE MARKET PRICE INFORMATION

         Both the Westell Class A Common Stock and the Teltrend common stock are
quoted on the Nasdaq National  Market.  An application will be made to quote the
Westell  Class A Common Stock to be issued in the merger on the Nasdaq  National
Market.  After the merger,  shares of Westell Class A Common Stock will continue
to be traded on the Nasdaq National Market under the symbol "WSTL."

         On  December  10,  1999,  the last  trading  date  prior to the  public
announcement  of the proposed  merger,  the last  reported  closing price on the
Nasdaq  National Market for the Westell Class A Common Stock was $10 3/4 and for
the Teltrend common stock was $23 1/8.  On  ____________,  2000, the most recent
available date prior to printing this joint proxy statement/prospectus, the last
reported  closing  price on the Nasdaq  National  Market for the Westell Class A
Common Stock was $__________ and for the Teltrend common stock was $__________.

OWNERSHIP OF WESTELL AFTER THE MERGER

         Westell  will  issue  approximately  19  million  shares of its Class A
Common Stock to Teltrend  stockholders  in the merger.  Upon  completion  of the
merger, this will represent approximately:

o        52% of Westell's outstanding Class A Common Stock;
o 34% of Westell's  outstanding  Class A Common Stock and Class B Common  Stock,
considered together; and o 17% of Westell's outstanding voting power.

         This  information  is based on the number of shares of Westell  Class A
Common  Stock and Class B Common  Stock and  shares  of  Teltrend  common  stock
outstanding  on ______ __, 2000,  and does not take into account stock  options,
Westell's warrants or Westell's convertible debentures. Assuming the exercise of
all  outstanding  options  (including  options  issued  upon  conversion  of the
outstanding  Teltrend options) and warrants to purchase Class A Common Stock and
the conversion of Westell's  outstanding  convertible  debentures at the current
conversion price, upon completion of the merger,  the Class A Common Stock to be
received by the Teltrend  stockholders  will represent  approximately 40% of the
outstanding  Class A Common Stock,  29% of the outstanding  Class A Common Stock
and Class B Common Stock,  considered together, and 16% of Westell's outstanding
voting power.

STOCKHOLDERS MEETINGS

         Both Teltrend and Westell are holding  special  meetings at which their
stockholders  will vote on proposals related to the merger. If you were a record
holder of Teltrend  common stock at the close of business on  __________,  2000,
you  will be  entitled  to vote at the  Teltrend  meeting.  If you were a record
holder  of  Westell  Class A Common  Stock or  Westell  Class B Common  Stock on
__________, 2000, you will be entitled to vote at the Westell meeting.

STOCKHOLDER VOTE REQUIRED

         The  affirmative  vote of a majority of the shares of  Teltrend  common
stock  outstanding on the record date is required to adopt the merger agreement.
As a result, a Teltrend stockholder that abstains or does not vote on the merger
is effectively voting against the merger. Each share of Teltrend common stock is
entitled to one vote. On the record date,  directors  and executive  officers of

<PAGE>


Teltrend  and their  affiliates  owned and were  entitled to vote ____ shares of
Teltrend  common  stock,  or  approximately  ___% of the  outstanding  shares of
Teltrend common stock.  These  individuals  and their  affiliates have indicated
that they will vote in favor of adoption of the merger agreement.

         The affirmative  vote of a majority of the total votes cast is required
to approve  the  issuance  of shares of  Westell's  Class A Common  Stock in the
merger and the affirmative vote of a majority of the total votes  outstanding on
the record date is required to approve the  amendment to  Westell's  Amended and
Restated  Certificate of Incorporation.  As a result, a Westell stockholder that
abstains  or  does  not  vote  on the  amendment  to  Westell's  Certificate  of
Incorporation is effectively voting against such amendment. Because Westell does
not presently have enough  un-reserved  shares of Class A Common Stock available
to issue in the merger, such a vote is accordingly a vote against the merger.

         Each share of Westell  Class A Common Stock  entitles its holder to one
vote and each share of Westell Class B Common Stock  entitles its holder to four
votes. On the record date, directors and executive officers of Westell and their
affiliates  owned and were entitled to vote ___ shares of Westell Class A Common
Stock and all outstanding  shares of Class B Common Stock, or approximately  __%
of  Westell's  outstanding  votes.  Two of  Westell's  directors,  who  are  the
co-trustees of the Westell Technologies, Inc. Voting Trust, and beneficially own
approximately  80% of the voting power of Westell,  have agreed to vote in favor
of the  merger  proposals  if a  majority  of  Westell's  non-affiliated  public
stockholders so vote. In addition, the co-trustees may also vote in favor of the
merger proposals even if a majority of the  non-affiliated,  public stockholders
reject the proposals.  The co-trustees have indicated their current intention to
vote as the majority of Westell's non-affiliated,  public stockholders vote with
respect to the  proposals.  The voting  agreement is described in more detail in
this joint  proxy  statement/prospectus.  See  "Voting  Agreement  with  Westell
Controlling Stockholders" on page II-18.

OPINIONS OF FINANCIAL ADVISORS

         In deciding to approve the merger,  among the factors  that the Westell
Board considered was the opinion of its financial advisor, Goldman, Sachs & Co.,
that, as of December 13, 1999, the exchange ratio of 3.3 shares of Westell Class
A Common Stock for each share of Teltrend  common  stock  pursuant to the merger
agreement was fair, from a financial point of view, to Westell. The full text of
the  written  opinion of Goldman  Sachs,  which  sets  forth  assumptions  made,
procedures followed, matters considered and limitations on the review undertaken
in  connection  with the  opinion,  is attached as  Appendix B.  Goldman  Sachs'
opinion  does not  constitute a  recommendation  as to how any holder of Westell
Class A Common  Stock  should  vote with  respect  to the merger  proposals.  We
encourage Westell stockholders to read the Goldman Sachs opinion. In deciding to
approve the merger,  the Westell Board also considered the advice of Hambrecht &
Quist, an additional  financial advisor retained by the Westell Board to provide
general advisory services with respect to the merger.

         In deciding to approve the merger,  among the factors that the Teltrend
Board considered was the opinion of its financial advisor,  SoundView Technology
Group,  Inc.,  that, as of December 13, 1999, the exchange ratio pursuant to the
merger  agreement  was fair,  from a financial  point of view, to the holders of
Teltrend common stock. The full text of the written opinion of SoundView,  which
sets forth the assumptions made,  procedures  followed,  matters  considered and
limitations on the review undertaken in connection with the opinion, is attached
hereto as Appendix C. We encourage  Teltrend  stockholders to read the SoundView
opinion.

INTERESTS OF OFFICERS AND DIRECTORS IN THE MERGER

         When you consider the Teltrend Board's recommendation that the Teltrend
stockholders  vote in favor of adoption of the merger  agreement,  you should be
aware that the  officers and  directors  of Teltrend  may have  interests in the
merger that may be different from yours.

         These  interests  exist  because  of the rights  some of the  executive
officers  have under a severance  plan  maintained  by Teltrend that Westell has
agreed to assume upon completion of the merger. This severance plan will provide
these officers with severance  benefits if their employment is terminated either
by Westell or, in certain  situations,  by the executive,  after the merger.  If
severance  benefits  were to be paid under this plan at the time of the  merger,
the  executive  officers  subject to the plan  would  receive  an  aggregate  of
approximately $3.2 million.

         In addition,  Westell's board of directors has agreed to appoint Howard
L. Kirby, Jr. and Bernard F.  Sergesketter,  currently the chairman of the board

<PAGE>


and chief  executive  officer and a director,  respectively,  of Teltrend to the
Westell board upon completion of the merger.

         In addition,  under the terms of Teltrend's existing option agreements,
all unvested options to purchase Teltrend common stock,  including those held by
directors and executive  officers,  will become fully vested and  exercisable in
connection  with the merger.  Those  options  which are not exercised or expired
before the merger will be converted into options to purchase  Westell's  Class A
Common Stock.

         Please review the section entitled  "Interests of Teltrend's  Directors
and Officers in the Merger" beginning on page II-29.

COMPARISON OF RIGHTS OF TELTREND AND WESTELL STOCKHOLDERS

         After the merger,  Teltrend stockholders will become holders of Westell
Class A Common  Stock and their rights as  stockholders  will be governed by the
Amended and Restated  Certificate of Incorporation and bylaws of Westell.  There
are some differences  between the  certificates of  incorporation  and bylaws of
Teltrend and  Westell.  For  example,  Westell has two classes of common  stock:
Class A Common  Stock and Class B Common  Stock.  Generally,  both  classes vote
together as a single class,  with each share of Class B Common Stock having four
votes and each share of Class A Common Stock having one vote.  In addition,  the
Class B Common  Stock is  effectively  controlled  by two Westell  directors  as
co-trustees   of  a  voting  trust.   This  control   gives  these   individuals
approximately 80% of Westell's current voting power and is expected to give them
approximately  68% of Westell's  voting power upon  consummation  of the merger.
Accordingly,  the rights of Teltrend stockholders as stockholders of Westell may
be  limited  from time to time by  actions  taken by the  holders of the Class B
Common Stock.  For a more complete  discussion,  see  "Material  Differences  in
Rights of Teltrend and Westell Stockholders" beginning on page V-1.

ACCOUNTING TREATMENT

         Westell and Teltrend  anticipate  that the merger will be accounted for
as a purchase. Merger related costs of approximately $5 million will be included
in the  determination  of the purchase  price.  Please see the section  entitled
"Westell and Teltrend Unaudited Pro Forma Condensed Consolidated Financial Data"
beginning on page II-24.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

         The merger is expected to be tax-free to Westell and  Teltrend for U.S.
federal income tax purposes. The merger is also expected to be tax-free for U.S.
federal  income tax  purposes to Teltrend  stockholders,  except with respect to
cash these stockholders  receive in lieu of fractional shares.  Stockholders are
urged to consult their own tax advisors.

NO APPRAISAL RIGHTS

         Neither the  Teltrend  stockholders  nor the Westell  stockholders  are
entitled to appraisal rights under Delaware law in connection with the merger.

REGULATORY APPROVAL

         Under the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976,  we
cannot  complete the merger  until  Westell and Teltrend  give  information  and
materials to the U.S.  Department  of Justice and Federal Trade  Commission  and
wait for a required waiting period to expire or terminate.  Westell and Teltrend
submitted  pre-merger  notification and report forms effective  January 3, 2000.
Unless  Westell or Teltrend  receives a request for  additional  information  or
documentary  materials,  the  waiting  period  under the HSR Act will  expire on
February 2, 2000, unless terminated earlier.

TERMINATION OF THE MERGER AGREEMENT; TERMINATION FEES

         Each of Westell and Teltrend can terminate the merger  agreement  under
certain  circumstances.  You should  review the  section  entitled  "The  Merger
Agreement - Termination of the Merger Agreement;  Termination Fees" beginning on
page IV-7 for details in that regard.

         Teltrend has agreed to pay to Westell a break-up  fee of  approximately
$7.2 million under the following circumstances:

     o    Teltrend  terminates  the merger  agreement  as a result of a superior
          proposal,  in accordance with the termination rights described on page
          IV-8;
     o    Westell terminates the merger agreement because the Teltrend Board has
          resolved  to accept a  superior  proposal  or has  recommended  to the
          Teltrend  stockholders that they tender their shares in a tender offer
          commenced by a third party; or

<PAGE>


     o    either Westell or Teltrend terminates the merger agreement because the
          Teltrend  stockholders have not adopted the merger agreement at a duly
          held meeting,  but only if Teltrend enters into a definitive agreement
          with  respect  to  an  acquisition  transaction  within  three  months
          following such termination.

         Westell has agreed to pay to Teltrend a break-up  fee of  approximately
$7.2 million under the following circumstances:

     o    either Westell or Teltrend terminates the merger agreement because the
          Westell Board  resolves to accept a superior  proposal  which requires
          the merger agreement to be terminated, but only if Westell enters into
          a  definitive  agreement  with respect to an  acquisition  transaction
          within nine months following such termination; or
     o    Westell,  in  the  limited  circumstances   permitted  by  the  merger
          agreement,  does not  recommend  to its  stockholders  approval of the
          proposals  described  in this joint proxy  statement/  prospectus  and
          Teltrend   terminates  the  merger   agreement   because  the  Westell
          stockholders  have  failed  to  approve  such  matters  at a duly held
          meeting  called for that  purpose,  but only if Westell  enters into a
          definitive agreement with respect to an acquisition transaction within
          three months following such termination.

      SUMMARY SELECTED HISTORICAL CONSOLIDATED AND PRO FORMA FINANCIAL DATA



HOW WE PREPARED THE FINANCIAL STATEMENTS

         We are providing the following  information to aid you in your analysis
of the financial  aspects of the merger.  We derived this  information  from the
consolidated financial statements of Westell and of Teltrend. The information is
only a summary and you should read it together  with  Westell's  and  Teltrend's
historical  financial  statements and related notes  contained in the underlying
reports and other  information that Westell and Teltrend have filed with the SEC
and incorporated into this joint proxy  statement/prospectus  by reference.  See
"Where You Can Find More Information" on page VI-1.

ACCOUNTING TREATMENT OF THE MERGER

         The  merger  will  be  accounted  for by  Westell  as a  purchase  of a
business.  This means that, for accounting and financial reporting purposes, the
assets and liabilities of Teltrend will be recorded at their fair value, and any
excess of Westell's  purchase price over the fair value of Teltrend's net assets
will be recorded as intangible assets, including goodwill.

         We have presented unaudited pro forma condensed  consolidated financial
information that reflects the purchase method of accounting to give you a better
understanding  of what our  businesses  might  have  looked  like had they  been
combined since April 1, 1998. The companies may have performed  differently  had
they  always  been  combined.  You  should not rely on the  unaudited  pro forma
condensed   consolidated  financial  information  as  being  indicative  of  the
historical  results  that the  combined  company  would  have had or the  future
results that it will experience after the merger.

MERGER-RELATED EXPENSES

         We estimate that merger-related fees and expenses, consisting primarily
of fees and expenses of  investment  bankers,  attorneys  and  accountants,  SEC
filing fees, fees and expenses of financial printing, and other related charges,
will be  approximately $ 5.0 million.  After the merger,  Westell may also incur
charges and expenses relating to integrating the operations of Teltrend.

(1)  Teltrend's  fiscal year normally  consists of four 13-week  quarters,  with
     each of the  first  three  quarters  ending  on the last  Saturday  of such
     quarter and the fourth  quarter  ending on the last  Saturday  in July.  In
     fiscal 1999,  the first  quarter  consisted  of 14 weeks.  The three months
     ended October 30 refer to Teltrend's  first fiscal  quarter.  First quarter
     1998 consisted of 14 weeks compared to 13 weeks in first quarter 1999.
(2)  Substantially all of Teltrend's  long-term  indebtedness was repaid in full
     upon  consummation  of its initial public offering which occurred in fiscal
     1995 in  conjunction  with a  recapitalization  of  Teltrend.  In addition,
     Teltrend  eliminated its valuation allowance for net deferred tax assets of
     approximately $3.4 million.
(3)  Pro forma  earnings per share and average  number of shares for fiscal 1995
     give effect to Teltrend's  initial public offering and the other components
     of its recapitalization, as if they occurred as of July 31, 1994.
(4)  On  September  18,  1997,  Teltrend  purchased  the  outstanding  shares of
     Securicor 3net Limited (since renamed  Teltrend  Limited).  The transaction
     was  accounted  for as a purchase  and  therefore  the  results of Teltrend
     Limited are included with the  operations  of Teltrend  since that date. As
     required by generally accepted accounting  principles,  Teltrend recorded a
     $4.0 million  charge  immediately  after the  acquisition  to write off the
     portion  of  the  purchase  price  allocated  to  in-process  research  and
     development costs.
(5)  On May 28, 1999 Teltrend sold substantially all of the assets of its packet
     switched  product  line  to  Contrecom   Systems  Limited  of  England  for
     approximately  $3.1  million.  The sale  resulted in a $1.3  million  loss,
     composed largely of the write-off of intangible  assets associated with the
     packet switched product line.

SELECTED UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

         For pro forma purposes, Westell's consolidated statements of operations
for the fiscal  year ended  March 31, 1999 and the  unaudited  six months  ended
September  30,  1999,  have  been  combined  with  the  unaudited   consolidated
statements  of  operations  of Teltrend for the twelve months ended May 1, 1999,
and for the six months ended October 30, 1999,  respectively,  both of which end
within 90 days of the  Westell  fiscal year end and  interim  reporting  period,
respectively.  In addition, Westell's unaudited consolidated balance sheet as of
September  30, 1999 has been  combined with  Teltrend's  unaudited  consolidated
balance  sheet as of  October  30,  1999.  This  selected  unaudited  pro  forma
consolidated  financial  information  should  be read in  conjunction  with  the
separate historical  financial  statements and accompanying notes of Westell and
Teltrend,   which  are   incorporated   by   reference   in  this  joint   proxy
statement/prospectus.  See "Where You Can Find More  Information"  on page VI-1.
The  unaudited  pro forma  consolidated  financial  data do not reflect any cost
savings  anticipated  as a result  of the  merger.  You  should  not rely on the
selected unaudited pro forma consolidated financial information as an indication
of the results of operations or financial position that would have been achieved
if the  merger  had taken  place  earlier or of the  results  of  operations  or
financial position of Westell after the completion of the merger.

UNAUDITED COMPARATIVE PER SHARE DATA

         In the table below,  we provide you with  historical  and pro forma per
share  information for Westell and historical and pro forma equivalent per share
information  for Teltrend as of and for the six months ended  September 30, 1999
and the fiscal year ended March 31,  1999.  We have  assumed for purposes of the
Westell pro forma  financial  information  that the merger had been completed on
April 1,  1998 for  income  statement  purposes,  and that the  merger  had been
completed on September  30, 1999 for balance  sheet  purposes.  The Teltrend pro
forma  equivalent   information  presents  Westell  pro  forma  per  share  data
multiplied by the exchange ratio of 3.3.

         The table also sets forth:

          o    for   December   10,  1999  (the  last  trading  day  before  the
               announcement  of the merger  agreement)  and  __________________,
               2000 (the last  practicable  trading  day before the  printing of
               this joint proxy statement/prospectus),  the closing sales prices
               of a share of Westell  Class A Common Stock and  Teltrend  common
               stock, as reported on the Nasdaq National Market; and
          o    the  equivalent  pro forma  market  price  per share of  Teltrend
               common stock as of those dates, assuming that the merger had been
               consummated  on those  dates.  This  equivalent  pro forma market
               price was determined by  multiplying  the exchange ratio of 3.3:1
               by the applicable price of Westell Class A Common Stock.

         It is  important  that when you read this  information,  you read along
with it the separate historical  financial  statements and accompanying notes of
Westell and Teltrend,  which are  incorporated  by reference in this joint proxy
statement/prospectus.  See "Where You Can Find More  Information"  on page VI-1.
You should not rely on the unaudited selected pro forma per share information as
an indication of the results of operations or financial position that would have
been  achieved  if the  merger  had taken  place  earlier  or of the  results of
operations or financial  position of Westell after the completion of the merger.
In addition, no assurances can be given as to the market prices of Westell Class
A Common Stock or Teltrend  common stock at, or, in the case of Westell  Class A
Common Stock, after, the effective time of the merger.  STOCKHOLDERS ARE ADVISED

                                  RISK FACTORS

         Both Teltrend  stockholders and Westell  stockholders  should carefully
consider  the  following  important  factors,  in  addition  to those  discussed
elsewhere in this document,  and in the documents that Westell and Teltrend have
filed with the SEC which are incorporated by reference,  to determine whether to
vote for the proposals relating to the merger.

SINCE THE MARKET PRICE OF THE WESTELL CLASS A COMMON STOCK FLUCTUATES,  TELTREND
STOCKHOLDERS  CANNOT BE SURE OF THE MARKET  VALUE OF THE WESTELL  CLASS A COMMON
STOCK THEY WILL RECEIVE IN THE MERGER.

         At the time the  merger is  completed,  each share of  Teltrend  common
stock will be converted  into the right to receive 3.3 shares of Westell Class A
Common Stock.  This exchange ratio of shares of Teltrend common stock for shares
of Westell  Class A Common  Stock is fixed and will not be adjusted in the event
of any increase or decrease in the market  price of either the  Teltrend  common
stock or the  Westell  Class A Common  Stock.  The price of either the  Teltrend
common  stock or the Westell  Class A Common Stock on the date of the merger may
vary from its price on the date of this joint proxy  statement/prospectus and on
the dates of the  stockholder  meetings.  The  variations  may be the  result of
changes in the business,  operations or prospects of Teltrend or Westell, market
assessments of the likelihood  that the merger will be completed and its timing,
regulatory  considerations,  general  market and economic  conditions  and other
factors.  As a result, the value of the Westell Class A Common Stock received by
Teltrend stockholders in the merger may be higher or lower than the market value
of the Westell  Class A Common Stock at the time you vote or at the date of this
joint proxy statement/prospectus.

WE MAY NOT BE ABLE TO SUCCESSFULLY INTEGRATE OUR OPERATIONS.

         In  determining  that the issuance of shares of Westell  Class A Common
Stock to the  Teltrend  stockholders  and the  merger is fair to and in the best
interests of their stockholders, both Boards considered, among other things, the
financial benefits, operating efficiencies and synergies expected to result from
the completion of the merger.

         A successful combination of the two companies will require, among other
things, integration of the two companies' respective:

          o    technological expertise and licensed technologies;
          o    strategic alliances;
          o    products and product development efforts;
          o    sales and distribution channels;
          o    manufacturing and sourcing;
          o    key personnel; and
          o    management information systems.

         Neither  company has been involved in a strategic  merger of this size,
in which effective integration of corporate cultures may be especially important
over the long term to achieve the benefits of the merger.  This  integration may
not be successfully  accomplished.  Moreover,  the integration of the operations
following  the merger  will  require  the  dedication  of  management  and other
personnel which may distract their attention from the day-to-day business of the
combined  companies,  the  development  or  acquisition  of new products and the
pursuit  of other  business  acquisition  activities.  Failure  to  successfully
accomplish the integration of the two companies' operations and technologies, or
a prolonged delay in accomplishing a reasonable measure of integration, may have
a material adverse effect on the combined company.

         In  addition,  as  a  consequence  of  the  merger,  both  the  Westell
stockholders and the Teltrend  stockholders  will lose the opportunity to invest
in the development and exploitation of their company's products on a stand-alone
basis.  Further,  with  respect to  Teltrend,  the  combined  company  will have
different  management than Teltrend's current  management,  and consequently the
management of the combined company may make strategic and operational  decisions
that differ from those of  Teltrend's  current  management.  It is possible that

<PAGE>


either  Westell or Teltrend,  if it were to remain  independent,  could  achieve
economic performance superior to that of the combined company.


WESTELL HAS INCURRED AND CONTINUES TO EXPECT LOSSES.

        Due to Westell's  significant  ongoing  investment in digital subscriber
line  technology,  which can be used by telephone  companies  and other  service
providers to increase the  transmission  speed and capacity of copper  telephone
wires, it has incurred and anticipates  that its losses may extend through March
31,  2000.  To date,  Westell  has  incurred  operating  losses,  net losses and
negative  cash flow on both an annual and quarterly  basis.  For the fiscal year
ended March 31, 1999, Westell had net losses of approximately $35.0 million. For
the six months ended September 30, 1999, Westell had net losses of approximately
$6.5 million.

         In  addition,  Westell  expects  the  combined  company to  continue to
evaluate  new  product  opportunities  and  engage  in  extensive  research  and
development  activities.  As a result,  the combined  company  will  continue to
invest heavily in research and development  and sales and marketing,  which will
adversely  affect  its  short-term  operating  results.  Westell  can  offer  no
assurances that it will achieve profitability in the future.

WESTELL IS CONTROLLED BY A LIMITED  NUMBER OF  STOCKHOLDERS,  WHOSE ACTIONS FROM
TIME TO TIME  COULD  LIMIT THE  RIGHTS OF  TELTREND  STOCKHOLDERS  AS HOLDERS OF
WESTELL CLASS A COMMON STOCK.

        At _________, 2000, Robert C. Penny III and Melvin J. Simon, as trustees
of a voting trust  containing  Westell Class B Common Stock held for the benefit
of the Penny family and the Simon family,  had the exclusive  power to vote over
80% of the votes entitled to be cast by the holders of Westell common stock.  In
addition,  all  members  of the Penny  family who are  beneficiaries  under this
voting  trust  are  parties  to a stock  transfer  restriction  agreement  which
prohibits them from  transferring  any Class B Common Stock or their  beneficial
interests in the voting trust  without  first  offering  such to the other Penny
family  members.  Consequently,  Westell  is  effectively  under the  control of
Messrs. Penny and Simon, as trustees,  who have sufficient voting power to elect
all of the directors and to determine the outcome of most corporate transactions
or other  matters  submitted  to the Westell  stockholders  for  approval.  This
control may have the effect of discouraging  transactions involving an actual or
potential  change of control of  Westell,  including  transactions  in which the
holders of Westell  Class A Common Stock might  otherwise  receive a premium for
their shares over the then-current market price.

         Upon completion of the merger, we expect that Messrs.  Penny and Simon,
as trustees,  will continue to have effective  control over Westell as described
above.  This is because,  even after  Westell  issues  approximately  19 million
shares of Class A Common Stock to Teltrend  stockholders in the merger,  Messrs.
Penny and Simon will  continue to have the  exclusive  power to vote over 68% of
the votes entitled to be cast by the holders of Westell common stock.

         Concurrently with the execution of the merger agreement,  Messrs. Penny
and Simon,  individually and as co-trustees of the voting trust, entered into an
agreement  with Teltrend  under which each of them has agreed to vote all of the
capital  stock of  Westell  for  which he has the  power to vote in favor of the
merger proposals if Westell's public stockholders vote in favor. For purposes of
the voting  agreement,  Westell's  public  stockholders  include  all holders of
Westell Class A Common Stock, other than Messrs.  Penny and Simon and members of
their  families  and any officers or  directors  of Westell.  In  addition,  the
co-trustees may also vote in favor of the merger proposals even if a majority of
the public  stockholders  reject the proposals.  The co-trustees  have indicated
their  current  intention to vote as the  majority of Westell's  non-affiliated,
public stockholders vote with respect to the proposals. For a description of the
voting  agreement,  you should see "Voting  Agreement  with Westell  Controlling
Stockholders" on page II-18.

FOLLOWING THE MERGER,  TELTREND STOCKHOLDERS MAY BE ADVERSELY AFFECTED BY FUTURE
ISSUANCES AND SALES OF WESTELL'S CLASS A COMMON STOCK.


<PAGE>


         Sales of  substantial  amounts of Westell  Class A Common  Stock in the
public market  following the merger could  adversely  affect the market price of
the  Westell  Class A  Common  Stock.  Westell  has  outstanding  the  following
obligations which require it to issue additional shares of Class A Common Stock:

          o    Westell has  outstanding  options to purchase  approximately  3.8
               million shares of Westell Class A Common Stock which were granted
               to employees from time to time as part of Westell's  compensation
               programs.  Upon  the  merger,  outstanding  options  to  purchase
               Teltrend commons stock will be converted into options to purchase
               Westell Class A Common Stock,  resulting in additional options to
               purchase  approximately  3.1  million  shares of Westell  Class A
               Common Stock becoming outstanding.
          o    Westell has reserved  131,825  shares of Class A Common Stock for
               issuance under its employee stock purchase plan.
          o    The 19,124,869 shares of Westell Class B Common Stock outstanding
               are convertible  into an equal number of shares of Class A Common
               Stock  under  circumstances  which are under the  control  of the
               holders thereof.  Messrs.  Penny and Simon, as co-trustees of the
               Westell Technologies,  Inc. Voting Trust, are entitled to require
               Westell to  register  for sale with the SEC the shares of Class A
               Common  Stock  issuable  upon  conversion  of the  Class B Common
               Stock.
          o    In April 1999,  Westell issued $20 million of debentures that are
               convertible into shares of Class A Common Stock. Currently, these
               debentures  are  convertible  into 3,138,731  shares,  which upon
               issuance would represent approximately 18% of Westell's currently
               outstanding  Class A Common  Stock  and 3% of  Westell's  current
               voting power. In addition, in connection with the issuance of the
               debentures  Westell issued warrants to purchase 909,091 shares of
               Class A Common Stock which  currently  have an exercise  price of
               $5.92.

         Westell's  convertible  debentures  are  convertible  into a number  of
shares of Class A Common Stock  determined by dividing the  principal  amount of
the convertible debentures by the lesser of:

          o    a variable  conversion price which is initially $6.372 per share,
               but  will  be  increased  under  the  terms  of  the  convertible
               debentures; and
          o    the floating market price of the Class A Common Stock at the time
               of conversion, except that the market price can be imposed only
               under specific conditions.

The number of shares of Class A Common Stock that may  ultimately be issued upon
conversion is presently  indeterminable  and could fluctuate  significantly.  To
illustrate  the  potential  dilution  that  may  occur  upon  conversion  of the
convertible  debentures,  the following table sets forth the number of shares of
Class A Common Stock that are convertible from the convertible debentures if the
conversion price is $6.372, which is the initial conversion price, $4 and $2 per
share.

</TABLE>

The variable  conversion  price formula could affect the Class A Common Stock as
follows:

          o    If Westell's Class A Common Stock trades at a price less than the
               variable  conversion price,  which is initially $6.372 per share,
               then the convertible  debentures will be convertible  into shares
               of Class A Common Stock at variable rates based on future trading
               prices of the Class A Common  Stock and events  that may occur in
               the future. The number of shares of Class A Common Stock issuable
               upon conversion of

<PAGE>


               the convertible  debentures will be inversely proportional to the
               market  price  of  the  Class  A  Common  Stock  at the  time  of
               conversion.
          o    To the  extent  that the  holders of the  convertible  debentures
               convert  and then sell their  Class A Common  Stock,  the Class A
               Common Stock price may decrease due to the  additional  shares in
               the  market,   allowing   holders  to  convert  the   convertible
               debentures into greater amounts of Class A Common Stock,  further
               depressing the stock price.
          o    The interest payable on the convertible debentures may be paid in
               cash, additional  convertible  debentures or Class A Common Stock
               at Westell's option. In this regard, the lower the Class A Common
               Stock price,  the more shares of Class A Common Stock the holders
               of  the  convertible   debentures  will  receive  in  payment  of
               dividends.
          o    The  significant  downward  pressure  on the price of the Class A
               Common Stock as the debenture  holders  convert and sell material
               amounts of Class A Common  Stock could  encourage  short sales by
               the holders or others,  placing further downward  pressure on the
               price of the Class A Common Stock.

         The warrants are also subject to  anti-dilution  protection,  which may
result in the  issuance of more shares than  originally  anticipated  if Westell
issues  securities at less than market value or the applicable  exercise  price.
These  factors  may result in  substantial  future  dilution  to the  holders of
Westell's  Class A Common Stock,  including,  following  the merger,  the former
Teltrend  stockholders.  Westell has filed a registration statement with the SEC
to register the resale of the shares  issuable upon conversion of the debentures
and exercise of the warrants.

         As a result of these obligations,  Teltrend stockholders may be subject
to  substantial  dilution  after the merger as holders of Westell Class A Common
Stock. This dilution could adversely impact Teltrend  stockholders by disrupting
the market for, and causing a decline in the trading price of, the Westell Class
A Common Stock.

THE COMBINED  COMPANY WILL DEPEND ON DIGITAL  SUBSCRIBER LINE MARKET  ACCEPTANCE
AND GROWTH FOR FUTURE SUCCESS.

         Westell  expects to continue  to invest  significant  resources  in the
development of digital subscriber line ("DSL") products.  Because the DSL market
is in its early stages,  Westell's DSL revenues have been difficult to forecast.
If the DSL market fails to grow or grows more slowly than anticipated,  then the
combined company's business,  revenues and operating results would be materially
adversely affected.

         Customers  have  only  recently  begun  to  consider  implementing  DSL
products in their  networks.  Westell has shipped  most of its DSL  products for
trials and early deployment.  Most of Westell's customers are in initial service
deployments and are not contractually bound to purchase Westell's DSL systems in
the  future.  Westell  is  unable  to  predict  whether  these  initial  service
deployments or other  technical or marketing  trials will be successful and when
significant  commercial  deployment of Westell's DSL products will begin,  if at
all.  The  timing of DSL  orders  and  shipments  can  significantly  impact the
combined company's revenues and operating results.

         Even  if the  combined  company's  customers  adopt  policies  favoring
full-scale  implementation of DSL technology,  the combined company's  DSL-based
sales may not become  significant.  There is no  guaranty  that  customers  will
select the combined company's DSL products instead of competitive  products.  If
the combined  company fails to  significantly  increase its DSL sales,  then its
business, operating results and financial condition will suffer.

PRICING  PRESSURES  ON PRODUCTS  MAY  ADVERSELY  AFFECT THE  COMBINED  COMPANY'S
PROFITABILITY.

         Due to competition  in the DSL market,  bids for recent field trials of
DSL products reflect:

          o    the forward  pricing of DSL products  below  production  costs to
               take into account the  expectation  of large  future  volumes and
               corresponding reductions in manufacturing costs; or

<PAGE>


          o    suppliers  providing  DSL  products at a lower price as part of a
               sale of a package of products  and/or  services  that include but
               are not limited to DSL products.

         Westell is offering  DSL  products  with a gross  profit  substantially
lower than its other  products.  Such pricing will have a negative impact on the
gross margins of the combined  company on a  substantial  portion of its product
sales unless and until it can reduce the costs associated with its DSL products.
Westell believes that the DSL product costs may decrease when:

          o    more cost-effective  transceiver and microprocessor  technologies
               are available;
          o    product design efficiencies are obtained; and
          o    additional  economies of scale are obtained  related to increased
               volume.

         There is no guaranty  that the combined  company will be able to secure
significant additional orders and reduce per unit product costs of DSL products.
The  combined  company  could  continue  to  experience  low  gross  margins  in
connection with sales of DSL products even if its DSL unit volume increases. Low
gross  margins  from DSL  products  could  result in  fluctuations  in quarterly
operating  results  and would  materially  and  adversely  affect  the  combined
company's profitability and ability to implement its business goals.

EVOLVING  INDUSTRY  STANDARDS  MAY ADVERSELY  AFFECT THE COMBINED  COMPANY'S DSL
SALES.

         Industry  wide  standardization  organizations  such  as  the  American
National  Standards  Institute  and the  European  Telecommunications  Standards
Institute are responsible for setting transceiver  technology  standards for DSL
products.  Because Westell has not internally developed a transceiver technology
for its  products,  it is  dependent  on  transceiver  technologies  from  third
parties.  Absent  the  proper  relationships  with  key  transceiver  technology
vendors,  the combined  company's  products  may not comply with the  developing
standards for DSL. If customers  require  standards-based  products that require
transceiver  technologies not available to the combined company under reasonable
terms, then its DSL revenues would  significantly  decrease and its business and
operating results would materially suffer.

         The combined company will continue to rely on third party suppliers for
access to transceiver  technologies  for new DSL products.  Since standards have
not  been   established   such   products,   there  can  be  no  assurance  that
standards-compliant  transceiver  technologies will be available to the combined
company in a timely manner for the purpose of product development.

         In addition,  the introduction of competing standards or implementation
specifications  could result in confusion in the market and delay any  decisions
regarding  deployment  of DSL systems.  Delay in the  announcement  of standards
would  materially  and  adversely  impact  sales of the combined  company's  DSL
product  offerings and could have a material  adverse effect on its business and
operating results.

THE  COMBINED  COMPANY'S  PRODUCTS  WILL FACE  COMPETITION  FROM OTHER  EXISTING
PRODUCTS,  PRODUCTS UNDER DEVELOPMENT AND CHANGING TECHNOLOGY,  AND THE COMBINED
COMPANY  MUST  DEVELOP  NEW  COMMERCIALLY  SUCCESSFUL  PRODUCTS  TO ACHIEVE  ITS
BUSINESS GOALS AND GENERATE REVENUE.

         The markets for Westell's and Teltrend's products are characterized by:

          o    intense competition,
          o    rapid technological advances,
          o    evolving industry standards,
          o    changing demographics such as shifts to home offices,
          o    modifications in end-user requirements,
          o    frequent new product introductions and enhancements, and
          o    evolving telephone company service offerings.


<PAGE>


         New product  introductions  or changes in  telephone  company  services
could render Westell's existing products and products under development obsolete
and  unmarketable.  For example,  High Bit-Rate DSL, a product that enhances the
signal quality of the  transmission  over copper wire, may reduce the demand for
Westell's traditional T-1 products. These products accounted for at least 50% of
its revenues in each of the last three  fiscal  years.  Further,  the demand for
many of Westell's  traditional  analog  products is decreasing,  and will likely
continue  to  decrease,  as high  capacity  digital  transmission  becomes  less
expensive and more widely  deployed.  Many of  Teltrend's  products face similar
trends.  There  can be no  assurance  that the  combined  company  will have the
financial  and  manufacturing  resources  necessary to continue to  successfully
develop new products or to otherwise successfully respond to changing technology
standards and telephone company service offerings. The combined company's future
success  will largely  depend upon its ability to continue to enhance  Westell's
and  Teltrend's  existing  products and to  successfully  develop and market new
products on a cost-effective and timely basis.

         Westell's and Teltrend's  current product  offerings apply primarily to
the delivery and  monitoring of digital  communications  over copper wire in the
local  access  network.   The  combined  company  expects  that  the  increasing
deployment  of fiber and  wireless  broadband  transmission  in the local access
network will reduce the demand for these existing products.  Telephone companies
also face  competition  from cable  operators,  new local access  providers  and
wireless  service  providers  that are capable of providing  high speed  digital
transmission  to end-users.  If telephone  companies  decide not to aggressively
respond to this  competition and fail to offer high speed digital  transmission,
then the overall demand for DSL products will decline.  Consequently,  to remain
competitive  the combined  company must develop new products to meet the demands
of these emerging transmission media and new local access network providers.

         If the  combined  company's  products  become  obsolete or fail to gain
widespread  commercial  acceptance due to competing  products and  technologies,
then its product  revenues  would  significantly  decrease  and its business and
operating results will be materially adversely affected.

THE COMBINED COMPANY MAY EXPERIENCE DELAYS IN THE DEPLOYMENT OF NEW PRODUCTS.

         Westell's and Teltrend's past sales have resulted from their ability to
anticipate  changes in  technology,  industry  standards and  telephone  company
service  offerings,  and to develop and introduce new and enhanced  products and
services. The combined company's continued ability to adapt to such changes will
be a significant factor in maintaining or improving its competitive position and
its prospects  for growth.  Factors  resulting in delays in product  development
include:

          o    rapid technological changes in the telecommunications industry;
          o    the regional bell operating  companies'  lengthy product approval
               and purchase processes;
          o    reliance on  third-party  technology  for the  development of new
               products; and
          o    consolidation  among the customer base  resulting in  operational
               disruptions.

There can be no assurance that the combined company will successfully  introduce
new products on a timely  basis or achieve  sales of new products in the future.
If the combined company fails to deploy new products on a timely basis, then its
product sales will decrease,  its quarterly  operating  results could fluctuate,
and its  competitive  position and financial  condition  would be materially and
adversely affected.

INDUSTRY CONSOLIDATION COULD MAKE COMPETING MORE DIFFICULT.

         Consolidation  of  companies  offering  high  speed  telecommunications
products  is  occurring  through  acquisitions,  joint  ventures  and  licensing
arrangements  involving  Westell's and  Teltrend's  competitors  and  customers.
Westell cannot provide any assurances that the combined  company will be able to
compete   successfully  in  an  increasingly   consolidated   telecommunications
industry.  Any heightened  competitive  pressures that the combined  company may

<PAGE>


face may have a material  adverse effect on its business,  prospects,  financial
condition and result of operations.

THE FAILURE TO  MAINTAIN  AND  FURTHER  DEVELOP  PARTNERS  AND  ALLIANCES  WOULD
ADVERSELY AFFECT THE COMBINED COMPANY'S BUSINESS.

         Instead of directly competing with large  telecommunications  equipment
suppliers,  Westell has begun to develop and maintain partnerships and alliances
with other  companies in order to secure  complementary  technologies,  to lower
costs, and to better market and sell products.  These partnerships and alliances
provide  important  resources  and channels for the combined  company to compete
successfully.  Some  of  Westell's  partnerships  provide  it with  third  party
technology that it relies on to manufacture its products.  In addition,  instead
of directly  competing  with large  suppliers  such as Lucent  Technologies  and
Fujitsu  in the DSL  market,  Westell  has  entered  into  alliances  with these
companies to offer products within a package of products sold by these companies
to  telephone  companies.  Westell  cannot  provide  any  assurances  that these
partnerships  will continue in the future.  As competition  increases in the DSL
market, these alliances will become even more important to the combined company.
A loss of one or more  partnerships  and  alliances  could  affect the  combined
company's ability to sell its products and therefore could materially  adversely
affect its business and operating results.

WESTELL'S  AND  TELTREND'S  LACK OF BACKLOG  MAY AFFECT THE  COMBINED  COMPANY'S
ABILITY TO ADJUST TO AN UNEXPECTED SHORTFALL IN ORDERS.

         Because  Westell and Teltrend each  generally  ship  products  within a
short period after receipt of an order, neither company typically has a material
backlog of unfilled  orders,  and  revenues  in any  quarter  are  substantially
dependent on orders booked in that quarter.  Westell's  and  Teltrend's  expense
levels are based in large part on anticipated future revenues and are relatively
fixed in the short-term. Therefore, the combined company may be unable to adjust
spending  in a timely  manner to  compensate  for any  unexpected  shortfall  of
orders.  Accordingly,  any  significant  shortfall  of  demand  in  relation  to
expectations  or any material delay of customer  orders would  adversely  affect
quarterly operating results and have an immediate adverse impact on the combined
company's business and operating results.

THE COMBINED  COMPANY WILL DEPEND ON A LIMITED  NUMBER OF CUSTOMERS WHO ARE ABLE
TO EXERT A HIGH DEGREE OF INFLUENCE OVER IT.

         Westell and Teltrend each have depended,  and the combined company will
continue to depend on a small number of customers for  substantially  all of its
revenues. these customers consist primarily of the large regional bell operating
companies,  which are the telephone  companies that emerged from the break-up of
AT&T. Sales to the regional bell operating  companies accounted for 61.9%, 51.1%
and 46.6% of Westell's revenues in fiscal 1997, 1998 and 1999,  respectively and
95.8%,  81.7% and 75.5% of  Teltrend's  revenues in fiscal 1997,  1998 and 1999,
respectively.  Consequently,  the combined  company's future success will depend
significantly upon:

          o    the  timeliness  and  size of  future  purchase  orders  from the
               regional bell operating companies;
          o    the  product   requirements   of  the  regional  bell   operating
               companies;
          o    the  financial  and  operating   success  of  the  regional  bell
               operating companies; and
          o    the success of the regional bell  operating  companies'  services
               that use its products.

         The regional bell  operating  companies  and  Westell's and  Teltrend's
other customers are significantly  larger and are expected to be able to exert a
high  degree  of  influence  over the  combined  company.  Customers  purchasing
Westell's or Teltrend's products may generally reschedule orders without penalty
to the customer. Even if demand for the combined company's products is high, the
regional bell operating companies have sufficient bargaining power to demand low
prices and other terms and conditions that may materially  adversely  affect the
combined company's business and operating results.


<PAGE>


         Any attempt by a regional bell operating  company or other customers to
seek out  additional  or  alternative  suppliers  or to  undertake  the internal
production  of products  would have a material  adverse  effect on the  combined
company's business and operating results.  The loss of any customer could result
in an immediate  decrease in product sales and materially  and adversely  affect
the combined company's business.

         Conference Plus,  Westell's 88% owned  subsidiary,  has a customer base
that is very  concentrated as well, with its ten customers  representing a large
portion  of  revenue.   Customers  of  Conference   Plus  have  expanded   their
requirements for its services, but there can be no assurance that such expansion
will  increase  in  the  future.   Additionally,   Conference  Plus's  customers
continually  undergo  review and  evaluation of their  conferencing  services to
evaluate the merits of bringing those services  in-house rather than outsourcing
those services.  There can be no assurance in the future that Conference  Plus's
customers  will  bring  some  portion  or all  of  their  conferencing  services
in-house.  Conference Plus must continually  provide higher quality,  lower cost
services to provide,  maintain and grow their customer base. Any loss of a major
account,  would have a material  adverse effect on Conference Plus. In addition,
any merger or  acquisition  of a major  customer  could have a material  adverse
effect on Conference Plus.

WESTELL'S AND  TELTREND'S  CUSTOMERS HAVE LENGTHY  PURCHASE  CYCLES WHICH AFFECT
THEIR ABILITY TO SELL PRODUCTS.

         Prior to selling products to telephone companies,  Westell and Teltrend
each must undergo lengthy approval and purchase  processes.  Evaluation can take
as little as a few months for products that vary slightly from existing products
or up to a year or more  for  products  based  on new  technologies  such as DSL
products.   Accordingly,  each  company  is  continually  submitting  successive
generations of its current products as well as new products to its customers for
approval.  The length of the  approval  process  can vary and is  affected  by a
number of factors, including the:

          o    complexity of the product involved,
          o    priorities of telephone companies,
          o    telephone companies' budgets, and
          o    regulatory issues affecting telephone companies.

         The requirement  that telephone  companies obtain FCC approval for most
new telephone  company  services prior to their  implementation  has in the past
delayed the  approval  process.  Such delays in the future could have a material
adverse affect on the combined company's  business and operating results.  While
Westell and Teltrend have each been successful in the past in obtaining  product
approvals from their customers, there is no guaranty that such approvals or that
ensuing sales of such products will continue to occur.

WESTELL AND TELTREND ARE DEPENDENT ON, AND WOULD NOT BE ABLE TO COMPETE WITHOUT,
THIRD PARTY TECHNOLOGY.

         Many  of  Westell's  and  Teltrend's  products  incorporate  technology
developed and owned by third parties. Consequently,  each company must rely upon
third  parties to develop and introduce  technologies  which enhance its current
products and to develop new products. Any impairment or termination of Westell's
or Teltrend's  relationship  with any  licensors of  technology  would force the
combined  company to find other  developers on a timely basis or develop its own
technology.  There is no  guaranty  that the  combined  company  will be able to
obtain the third-party technology necessary to continue to develop and introduce
new and  enhanced  products,  that  it will  obtain  third-party  technology  on
commercially  reasonable  terms or that it will be able to  replace  third-party
technology  in the  event  such  technology  becomes  unavailable,  obsolete  or
incompatible  with  future  versions of the  combined  company's  products.  The
combined company would have severe  difficulty  competing if it cannot obtain or
replace the third-party  technology  used in its products.  Any absence or delay
would materially  adversely affect the combined company's business and operating
results.

         For  example,  Westell's  ability to produce DSL  products is dependent
upon  third  party  transceiver   technologies.   Westell's   licenses  for  DSL
transceiver technology are nonexclusive and the transceiver  technologies either
have been licensed to numerous other  manufacturers  or do not require a license

<PAGE>


to acquire. If Westell's DSL transceiver licensors fail to deliver implementable
or standards compliant transceiver solutions to it and other alternative sources
of  DSL  transceiver  technologies  are  not  available  to it  at  commercially
acceptable  terms,  then the combined  company's  business and operating results
would be materially and adversely affected.

WESTELL AND TELTREND ARE DEPENDENT ON SOLE OR LIMITED SOURCE SUPPLIERS AND COULD
NOT SELL THEIR PRODUCTS WITHOUT THESE SUPPLIERS.

         Integrated  circuits and other electronic  components used in Westell's
and  Teltrend's  products  are  currently  available  from only one  source or a
limited number of suppliers. For example, Westell currently depends on GlobeSpan
Technologies,  Alcatel  Microelectronics  and Analog  Devices,  Inc.  to provide
critical integrated  transceiver circuits used in its DSL products. In addition,
some of the electronic  components used in Westell's and Teltrend's products are
currently in short supply and are provided on an allocation basis to Westell and
other  users  based upon past  usage.  There is no  guaranty  that the  combined
company will be able to continue to obtain  sufficient  quantities of integrated
circuits or other electronic components as required, or that such components, if
obtained,  will be available to the combined company on commercially  reasonable
terms.  Integrated  transceiver  circuits  and  electronic  components  are  key
components in all of Westell's and  Teltrend's  products and are  fundamental to
the  combined  company's  business  strategy of  developing  new and  succeeding
generations of products at reduced unit costs without compromising functionality
or serviceability.  In the past Westell has experienced delays in the receipt of
key  components  which have  resulted in delays in related  product  deliveries.
Westell anticipates that integrated circuit production capacity and availability
of some  electronic  components may be  insufficient to meet the demand for such
components in the future.  The inability to obtain  sufficient key components or
to develop alternative sources for such components as required,  could result in
delays or  reductions in product  shipments,  and  consequently  have a material
adverse effect on the combined company's customer relationships and its business
and operating results.

WESTELL'S  AND  TELTREND'S   SERVICES  ARE  AFFECTED  BY  UNCERTAIN   GOVERNMENT
REGULATION AND CHANGES IN CURRENT OR FUTURE LAWS OR  REGULATIONS  COULD RESTRICT
THE WAY THE COMBINED COMPANY OPERATES ITS BUSINESS.

         Many of Westell's  and  Teltrend's  customers are subject to regulation
from  federal and state  agencies,  including  the FCC and various  state public
utility and service  commissions.  While such  regulations do not affect Westell
and Teltrend  directly,  the effects of such  regulations on their customers may
adversely  impact the combined  company's  business and operating  results.  For
example, FCC regulatory policies affecting the availability of telephone company
services and other terms on which telephone companies conduct their business may
impede  the  combined  company's   penetration  of  local  access  markets.  The
Telecommunications  Act lifted  certain  restrictions  on  telephone  companies'
ability to provide interactive multimedia services. Rules to implement these new
statutory  provisions  are now being  considered by the FCC. While the statutory
and regulatory  framework for telephone companies providing  multimedia services
has become more  favorable,  it is  uncertain  at this time how this will affect
telephone companies' demand for products based upon DSL technology. In addition,
the  combined  company's  business and  operating  results may also be adversely
affected by the imposition of tariffs,  duties and other import  restrictions on
components that it obtains from  non-domestic  suppliers or by the imposition of
export restrictions on products that it sells internationally.  Internationally,
governments  of  the  United  Kingdom,  Canada,  Australia  and  numerous  other
countries  actively  promote and create  competition  in the  telecommunications
industry.  Changes in  current or future  laws or  regulations,  in the U.S.  or
elsewhere, could materially and adversely affect the combined company's business
and operating results.

         In  addition,  the  Telecommunications  Act permits the  regional  bell
operating  companies  to  engage  in  manufacturing  activities  after  the  FCC
authorizes a regional bell operating  company to provide long distance  services
within its service territory.  A regional bell operating company must first meet
specific  statutory and regulatory tests  demonstrating that its monopoly market
for local telephone  services is open to competition before it will be permitted
to enter the long  distance  market.  When these tests are met, a regional  bell
operating  company will be permitted to engage in  manufacturing  activities and
the regional  bell  operating  companies,  which are  Westell's  and  Teltrend's
largest customers, may become the combined company's competitors as well.

WESTELL'S  FAILURE TO MANAGE THE COMBINED  COMPANY'S  GROWTH  EFFECTIVELY  COULD
IMPAIR ITS ABILITY TO SUPPLY AND SUPPORT THE MANUFACTURE OF LARGE VOLUMES OF DSL
PRODUCTS.

         Westell  is  in  the   process  of  planning   for  the   manufacturing
capabilities  necessary to supply and support  large volumes of DSL products and
in the  future  the  combined  company  may  become  increasingly  dependent  on
subcontractors.  Reliance on third-party  subcontractors involves several risks,
including the potential  absence of adequate  capacity and reduced  control over
product quality,  delivery schedules,  manufacturing yields and costs.  Although
Westell believes that alternative  subcontractors  or sources could be developed
if  necessary,  the use of  subcontractors  could  result in material  delays or
interruption of supply as a consequence of required  re-tooling,  retraining and
other activities  related to establishing and developing a new  subcontractor or
supplier  relationship.  Any material  delays or difficulties in connection with
increased  manufacturing  production or the use of  subcontractors  could have a
material  adverse  effect  on the  combined  company's  business  and  operating
results.  The combined  company's failure to effectively manage its growth would
have a material adverse effect on its business and operating results.

THE COMBINED  COMPANY'S  FAILURE TO RETAIN KEY PERSONNEL AND HIRE ADDITIONAL KEY
PERSONNEL COULD ADVERSELY  AFFECT ITS ABILITY TO SUCCESSFULLY  COMPETE,  DEVELOP
AND SELL NEW PRODUCTS.

         Because of Westell's and Teltrend's  need to  continually  evolve their
businesses with new product developments and strategies,  the combined company's
success  will be  dependent,  in part,  on its  ability  to  attract  and retain
qualified  technical,  marketing,  sales  and  management  personnel.  To remain
competitive  in the  telecommunications  industry,  the  combined  company  must
maintain top management  talent,  employees who are involved in the  development
and  testing  of new  products,  and  employees  who  have  developed  important
relationships  with key customers.  Because of the high demand to these types of
key employees,  especially in the DSL market, it is difficult to retain existing
key employees and attract new key employees.  While most of Westell's  executive
officers  have  severance  agreements  in which the officers  have agreed not to
compete with it and not to solicit any of its employees for a period of one year
after termination of the officer's  employment in most  circumstances,  Teltrend
generally does not have similar  noncompetition and  nonsolicitation  agreements
for its  employees  and  Westell  does not have  similar  agreements  for  other
employees who are important in its product  development and sales.  The combined
company's  inability to attract and retain  additional key employees or the loss
of one or more of Westell's or Teltrend's current key employees could materially
adversely  affect the combined  company's  ability to  successfully  develop new
products and implement its strategy.

WESTELL'S STOCK PRICE IS VOLATILE.

         Westell's  Class A  Common  Stock  price  has  experienced  substantial
volatility  in the past and is likely to remain  volatile  in the  future due to
factors such as:

          o    Westell's   historical  and  anticipated   quarterly  and  annual
               operating results;
          o    Variations  between  Westell's  actual  results  and  analyst and
               investor expectations;
          o    Announcements by Westell or others and developments affecting our
               business;
          o    Investor  perceptions of Westell and comparable public companies;
               and
          o    Conditions   and   trends   in  the   data   communications   and
               Internet-related industries.

         In  particular,  the stock  market  has from  time to time  experienced
significant  price  and  volume  fluctuations  affecting  the  common  stocks of
technology companies,  which may include  telecommunications  manufacturers like
Westell.  Volatility  can  also  arise as a result  of the  activities  of short
sellers and risk arbitrageurs  regardless of the combined company's performance.
This  volatility  may  result in a material  decline in the market  price of the
Westell Class A Common Stock,  and may have little  relationship to the combined
company's financial results or prospects.

THE  COMBINED  COMPANY'S  QUARTERLY  OPERATING  RESULTS ARE LIKELY TO  FLUCTUATE
SIGNIFICANTLY   AND  SHOULD  NOT  BE  RELIED  UPON  AS   INDICATIONS  OF  FUTURE
PERFORMANCE.

         Westell expects to continue to experience  significant  fluctuations in
quarterly  operating  results.  Due to the factors set forth below and elsewhere
contained in these "Risk  Factors,"  sales to Westell's and  Teltrend's  largest
customers have  fluctuated and are expected to fluctuate  significantly  between
quarters.  Sales to customers typically involve large purchase commitments,  and
customers  purchasing  Westell's or Teltrend's products may generally reschedule
or cancel orders without penalty.  As a result,  Westell's  quarterly  operating
results have  fluctuated  significantly  in the past three fiscal  years.  Other
factors  that  have  had and  may  continue  to  influence  Westell's  quarterly
operating results include:

          o    the  impact of  changes in the DSL  customer  mix or product  mix
               sold;
          o    timing of product  introductions  or enhancements by the combined
               company or its competitors;
          o    changes in operating  expenses which can occur because of product
               development costs, timing of customer reimbursements for research
               and development, pricing pressures and other reasons;
          o    write-offs for obsolete inventory; and
          o    the  other  risks  that  are  contained  in this  "Risk  Factors"
               section.

         Due to Westell's  fluctuations in quarterly  results,  it believes that
period-to-period   comparisons  of  its  quarterly  operating  results  are  not
necessarily  meaningful.  Quarterly  fluctuations  make  it  more  difficult  to
forecast  the  combined  company's  revenues.  It is likely  that in some future
quarters  Westell's   operating  results  will  be  below  the  expectations  of
securities  analysts and investors,  which may adversely affect its stock price.
This  occurred  in  fiscal  1999.  Westell  attempt  to  address  this  possible
divergence  through  its  public   announcements  and  reports.  The  degree  of
specificity Westell can offer in such announcements, however, and the likelihood
that any  forward-looking  statements it makes will prove correct,  can and will
vary.  As  long as the  combined  company  continues  to  depend  on DSL and new
products,  there  is  substantial  risk of  widely  varying  quarterly  results,
including the so-called "missed quarter" relative to investor expectations.

CONFERENCE  PLUS'S LARGE  COMPETITORS  COULD ADVERSELY AFFECT  CONFERENCE PLUS'S
ABILITY TO MAINTAIN OR INCREASE ITS MARKET SHARE.

         Conference Plus,  Westell's 88% owned  subsidiary,  participates in the
highly  competitive  industry  of  voice,  video,  and  multimedia  conferencing
services.  Competitors  include  stand-alone  conferencing  companies  and major
telecommunications  providers. In addition, internet service providers and other
entrants  may attempt to expand their  revenue  base by  providing  conferencing
services.  Conference  Plus's  ability to  sustain  growth  and  performance  is
dependent on its:

          o    maintenance of high quality standards and low cost position;
          o    international expansion;
          o    retention and addition of key personnel; and
          o    evolving technological capability.

Any  increase in  competition  could  reduce  Westell's  gross  margin,  require
increased  spending on research and  development  and sales and  marketing,  and
otherwise  materially  adversely  affect the  combined  company's  business  and
operating  results.  Westell is  currently  considering  a proposal  to spin-off
Conference Plus in the next 12 to 24 months.

                                   CHAPTER TWO
                                 THE TRANSACTION

                                  THE COMPANIES

WESTELL TECHNOLOGIES, INC.

         Since 1980,  Westell has  developed  telecommunications  products  that
address the needs of  telephone  companies  to upgrade  their  existing  network
infrastructures  in order to deliver  advanced data and voice  services to their
customers. Westell designs, manufactures,  markets and services a broad range of
digital and analog  products  used by telephone  companies  to deliver  services
primarily  over  existing  copper  telephone  wires that  connect end users to a
telephone  company's  central office.  This is commonly referred to as the local
loop or the local access network. Westell also markets its products and services
to other  telecommunications  and information  service  providers seeking direct
access to end user customers.

         Traditionally,  telephone companies have provided services using analog
transmission, which involves the transmission of wave signals that correspond to
the information being transmitted.  Analog  transmission,  however, is unable to
provide  the  requisite  volume,  speed and  reliability  to support the growing
demands for services over telephone  wires.  In contrast,  digital  transmission
makes it  possible  to reduce  all forms of  images,  sounds  and data to simple
digital  signals  of  ones  and  zeros  and  consequently   permits  high-speed,
high-volume  and highly  reliable data  transmission.  In the U. S., the digital
conversion of the analog  network has been built on the format known as T-1. T-1
transmission  utilizes a data rate that is 24 times faster than standard  analog
transmission,  or a rate  equal  to  1.54  megabits  per  second.  Further,  T-1
transmission can be aggregated or subdivided into channels that can deliver data
transmission tailored to specific end user requirements.

         Westell's products can be categorized into three groups:

          o    HiCAP  products:  products  that  maintain,  repair  and  monitor
               special circuits in the local loop that have higher capacity than
               normal telephone circuits. Special circuits are those that enable
               high-speed  digital  transmission at rates that are called T-1 or
               DS-3 rates in the U.S. and E-1 rates outside the U.S.
          o    CPE (Customer Premise Equipment) products:  modems that reside at
               end-user   locations  based  on  digital  subscriber  line  (DSL)
               technologies. DSL technology allows the simultaneous transmission
               of data at speeds up to 140 times faster than traditional  analog
               telephone service in one direction, or 8 megabits per second, and
               up to 17 times faster than traditional  analog telephone  service
               in the reverse  direction,  or 1 megabit  per second,  while also
               providing traditional analog telephone service over a single pair
               of copper wires at  distances of up to 18,000 feet,  depending on
               the transmission rates.
          o    Transport  systems  products:  products  that  include  both  DSL
               equipment  that is  used  in  telephone  companies'  and  service
               providers'  equipment  offices,  commonly  referred to as central
               offices,  as  well  as  products  that  monitor,   maintain,  and
               safeguard  wireless  networks and the demarcation  points between
               wireless networks and traditional phone networks that are used in
               central offices, in outdoor locations and on customers' premises.

         Conference Plus, Inc., Westell's 88% owned subsidiary,  provides audio,
video,  and data  conferencing  services.  Businesses and  individuals use these
services to hold voice,  video or data  conferences with many people at the same
time. Conference Plus sells its services directly to large customers,  including
Fortune  100  companies,  and serves  customers  indirectly  through its private
reseller  program.  Westell is  currently  considering  a proposal  to  spin-off
Conference Plus in the next 12 to 24 months.

         Westell  was  incorporated  in 1980  under  the  laws of the  State  of
Delaware and has its principal  executive  offices at 750 North  Commons  Drive,
Aurora,  Illinois 60504  (telephone  number:  630-898-2500).  Internet users can

TELTREND INC.

         Like Westell, Teltrend designs,  manufactures and markets a broad range
of  transmission  products that are used by telephone  companies to provide data
and voice services over the existing telephone  network,  primarily in the local
loop.  Teltrend also manufactures a wide range of products that convert,  change
and amplify transmission  protocols and are used worldwide in public and private
communications  networks.  Teltrend's products provide  transmission of data and
voice  over the  copper-wire  network  and  permit the  telephone  companies  to
maximize use of the existing infrastructure of copper wireline.

         Teltrend  manufactures a broad range of products necessary to provision
the local loop which are  designed  for  installation  either at the  end-user's
premises,  along  the  copper  wires  of the  local  loop  or at  the  telephone
companies' central offices. Teltrend's principal products are as follows:

          o    High capacity products: Teltrend's high capacity products include
               traditional T-1 line and office repeaters, which are installed to
               restore  and  amplify  T-1  signals  that  degrade  as  they  are
               transmitted,  and T-1  network  interface  units  and  associated
               mountings.  Its  products  also include ,  CellPak(TM)  units for
               cellular  and  wireless  base station  sites,  and high  bit-rate
               digital subscriber line ("HDSL") systems,  which are an alternate
               method of  delivering  T-1 services in the local loop that do not
               require  line   conditioning  or  the  installation  of  mid-span
               repeaters for distances up to 12,000 feet.
          o    Channelized  products:  Teltrend's  channelized  products include
               digital loop carrier and voice  frequency  products,  including a
               small  digital loop carrier  system,  plug-in  units for existing
               digital  loop carrier  systems and  traditional  voice  frequency
               products.  Digital loop  carriers  are deployed  within the local
               loop to interface  fiber-optic or some other transmission  medium
               to the  copper  wire line that  runs to an  end-user's  premises.
               Teltrend's  products  also include  integrated  services  digital
               network ("ISDN")/digital data system ("DDS") products,  including
               ISDN  and DDS  line  repeaters,  and  ISDN  and  DDS D-4  circuit
               assemblies  commonly  referred to as channel units.  ISDN and DDS
               are alternate  technologies  used to provide digital  services in
               the local loop at rates from 64 to 128 kbit/sec.
          o    Conversion  products:  These products include network interfacing
               and protocol conversion products.

         During the first nine months of  Teltrend's  fiscal year ended July 31,
1999,  Teltrend  also  offered a line of  connections  for local  area  computer
networks,  remote network access solutions and secure networking  products which
it  referred  to as its packet  switched  products  business.  On May 28,  1999,
Teltrend sold  substantially  all of the assets of its packet switched  products
business.

         Teltrend  was  incorporated  in 1987  under  the  laws of the  State of
Delaware and has its  principal  executive  offices at 620 Stetson  Avenue,  St.
Charles,  Illinois 60174 (telephone  number:  630-377-1700).  Internet users can
obtain information about Teltrend and its services at http://www.teltrend.com.

THETA ACQUISITION CORP.

         Theta Acquisition Corp. is a Delaware  corporation formed by Westell in
December 1999 under the laws of the State of Delaware  solely for the purpose of
merging into Teltrend.  Theta Acquisition Corp. is wholly owned by Westell.  The
mailing address of Theta Acquisition  Corp.'s principal executive offices is c/o
Westell  Technologies,  Inc.,  750 North Commons Drive,  Aurora,  Illinois 60504

                                   THE MERGER

GENERAL

         Each of the Westell  Board and the  Teltrend  Board is using this joint
proxy  statement/prospectus  to solicit  proxies  from the holders of its common
stock for use at the Westell special meeting or the Teltrend special meeting, as
the case may be. See Chapter III - "The Meetings and Voting."

         The merger agreement provides for the merger of a subsidiary of Westell
with and into Teltrend. As a result of the proposed merger, Teltrend will become
a wholly  owned  subsidiary  of Westell.  Based on the closing  price of Westell
Class A Common  Stock on  December  10,  1999,  the last  trading  day before we
publicly  announced  the signing of the merger  agreement,  had the merger taken
place each share of Teltrend  common  stock would have been  converted  into the
right to  receive  3.3 shares of  Westell  Class A Common  Stock with a value of
$10.75 per share.  This  represented  a 53% premium  over the  closing  price of
Teltrend  common stock on that date.  Had the merger taken place on  __________,
2000,  the last  available  trading date before the printing of this joint proxy
statement/prospectus,  each  share of  Teltrend  common  stock  would  have been
converted  into the right to receive 3.3 shares of Westell  Class A Common Stock
with a value of  $________  per  share,  based on that day's  closing  price for
Westell.  When we complete the merger,  the market value of  consideration  into
which each share of Teltrend common stock is converted in the merger may be more
or less than either of these  amounts,  depending on the market value of Westell
Class A Common Stock at that time.

BACKGROUND OF THE MERGER

         In early  October  1998,  a  representative  of  Teltrend's  investment
banking  firm,  SoundView,  contacted  Marc Zionts,  Westell's  chief  executive
officer,  and  expressed  Teltrend's  interest in exploring the  acquisition  of
Westell's  HiCAP  business  (as  described  in  the  section  entitled  "Westell
Technologies,  Inc." on page  II-1).  At this time,  Westell was  exploring  its
options for improving its operating efficiencies,  and expansion was selected as
one option to consider. In this regard,  Westell had reviewed numerous companies
in the Chicago  area,  including  Teltrend,  and had concluded  that  Teltrend's
complementary  technology,  customer base and close proximity  provided the best
option for expansion. As a result of the Teltrend inquiry, discussions were held
between Westell and Teltrend to explore  possibilities  of a strategic  business
transaction.

         Throughout November and December 1998, J. Nelson,  Westell's president,
and Howard Kirby,  Teltrend's chief executive officer,  met and discussed mutual
business  opportunities.   Throughout  these  discussions,  Mr.  Kirby  conveyed
Teltrend's desire to purchase Westell's HiCAP and non-DSL transport  businesses,
but expressed a growing interest in a potential merger.

         In December 1998, Teltrend signed an agreement with SoundView to pursue
merger and acquisition opportunities.

         Discussions  between Westell and Teltrend ceased until March 1999, when
Messrs.  Nelson and Kirby again agreed that there were compelling synergies that
could be achieved in a merger.

         In late May, Westell contacted its investment  bankers,  Goldman Sachs,
to assist  Westell in  determining  whether it should  pursue  continued  merger
discussions  with  Teltrend.  Westell  determined  that such a merger still made
sense to pursue. As a result,  Westell  management  continued  developing models
using  publicly  available  data to  ascertain  the  validity of such a business
combination.  Westell also retained Hambrecht & Quist,  investment  bankers,  to
review the analysis prepared by Westell's management. Based upon the findings of
management and both investment  banking firms,  the Westell board requested that
Westell management re-engage in discussions with Teltrend management.

         On June 1, 1999, Mr. Zionts, Mr. Nelson and Melvin J. Simon, a director
of Westell, met with Mr. Kirby and Douglas Hoffmeyer, Teltrend's chief financial
officer to discuss possible  valuations in a merger  transaction.  On August 11,
1999,  Mr.  Nelson and Mr.  Kirby met again to  discuss a possible  transaction.
Discussions continued between Teltrend and Westell throughout August.


<PAGE>


         On September 9, 1999,  Westell and Teltrend  executed a confidentiality
agreement.  Also on that date, a meeting was held with  executives  from Westell
(Messrs.  Zionts and  Nelson,  together  with Marc  Hafner,  an  executive  vice
president  of Westell and Bill Noll,  a senior vice  president  of Westell)  and
Teltrend (Messrs. Kirby and Hoffmeyer,  together with Jack Parker, a senior vice
president of Teltrend),  with investment bankers from both companies present. At
this meeting,  Westell  presented a general overview of its company and business
units and  products,  a summary of its  manufacturing  capability  and  facility
capacity and a financial summary and perspective on the benefits of the proposed
merger.  Teltrend presented its strategic directions for fiscal years 2000-2002,
including an overview of Teltrend's base products and growth targets by business
unit.  Teltrend also  presented a financial  update and its  perspective  on the
synergy that could be achieved in a merger.

         On September 17, 1999,  Westell  presented  Teltrend with a non-binding
proposal  outlining  the terms  under which  Westell was  prepared to enter into
merger discussions. From September 21 through November 2, representatives of the
parties and their  financial  advisors  negotiated the terms of the  non-binding
term sheet,  including the exchange ratio, board representation and treatment of
options.  In the course of these  negotiations,  on October  22,  1999,  Messrs.
Zionts and Nelson, together with Robert Gaynor,  Westell's Chairman of the Board
and then chief executive officer, made a presentation to the Teltrend Board with
respect to the potential  merger.  On November 2, 1999, the parties executed the
non-binding term sheet.

         Throughout  November  1999,  representatives  of the  companies  met to
discuss due diligence issues as well as corporate  communication  and synergies.
The parties' formal due diligence  investigations  began the week of November 8,
1999 and continued until the merger agreement was signed.

         On November 11, 1999,  Westell  presented  Teltrend with a draft merger
agreement  and on  November  23,  1999,  representatives  of  both  Westell  and
Teltrend,  together  with their legal  counsel and  financial  advisors,  met to
negotiate the terms of the merger agreement and related documents. From November
24, 1999 through December 13, 1999,  representatives of Westell and Teltrend and
their  respective  financial  advisors  and  legal  counsel  held  a  series  of
telephonic  meetings,  at which the  parties  negotiated  the final terms of the
merger,  the merger agreement and related  documents.  During November and early
December,  the  Teltrend  Board and the  Westell  Board each,  separately,  held
several meetings to discuss the progress of due diligence,  the negotiations and
the transaction generally.

         On December 13, 1999,  the Board of Directors of Westell held a special
meeting,  at which the Westell  Board  members  unanimously  approved the merger
agreement and recommended  that the stockholders of Westell vote in favor of the
merger proposals.

         Also on December  13, 1999,  the Board of Directors of Teltrend  held a
special meeting,  at which the Teltrend Board members  unanimously  approved the
merger agreement and recommended that the stockholders of Teltrend vote in favor
of the adoption of the merger agreement.

WESTELL'S REASONS FOR THE MERGER; RECOMMENDATION OF THE WESTELL BOARD

         Westell is pursuing the merger for the following reasons:

          o    Combining  the  Teltrend  business  into  Westell's  facility  is
               expected to result in operating  efficiencies at the gross margin
               and operating  income levels.  Larger volume material  purchases,
               facility overhead  allocable to more revenue,  operating expenses
               synergies  and other cost  reductions  should  account  for these
               efficiencies.
          o    The  positive  impact on cash flow  generated  from the  combined
               businesses,   Teltrend's   significant   cash  balances  and  the
               opportunity to turn redundant  assets into additional  cash, will
               help provide additional resources to grow the combined companies'
               DSL businesses.
          o    Westell's  income tax loss  carryover will be available to offset
               future  taxable  income  of  the  combined  companies,  providing
               another positive effect on cash flow and earnings.
          o    The  addition  of  Teltrend  products  such as HDSL,  channelized
               products and conversion  products will broaden  Westell's product
               portfolio.

<PAGE>


          o    In the areas where  Westell and Teltrend  have similar  products,
               the opportunity will exist for the selection of a "best of breed"
               product platform which should provide the combined  entities with
               additional flexibility and efficiencies.
          o    With the  current  consolidation  in  their  customer  base,  the
               combined  companies  should  be in a  stronger  position  to gain
               mindshare of these larger  companies and to meet their  expanding
               needs with the additional  operating scale provided by a combined
               Westell and Teltrend.

         On December 13, 1999, the Westell Board unanimously approved the merger
agreement and the transactions contemplated thereby. In making its decision, the
Westell Board  consulted with  Westell's  management and its financial and legal
advisors and considered various factors, including those listed below:

          o    information  concerning the financial  performance and condition,
               business operations,  capital levels, asset quality and prospects
               of each company,  and the projected future financial  performance
               of each company as a separate entity and on a combined basis;
          o    current industry, economic and market conditions and trends;
          o    the  importance  of  significant  scale and  scope and  financial
               resources to a company's ability to compete effectively globally;
          o    the   possibility   that   achieving   cost  savings,   operating
               efficiencies and synergies as a result of consummating the merger
               at this time might not be  available to the same degree to either
               company on its own;
          o    the  risk  that  the   combined   company  may  not  realize  the
               anticipated cost savings, operating efficiencies and synergies;
          o    the  judgment,  advice  and  analysis  of  Westell's  management,
               including the results of Westell's due diligence investigations;
          o    the terms of the merger agreement;
          o    the current and  historical  market prices of the common stock of
               each company;
          o    the risks  associated with a fixed exchange ratio,  including the
               risk that,  because the  exchange  ratio will not be adjusted for
               changes  in the  market  price of either  Westell  Class A Common
               Stock  or  Teltrend  common  stock,  the per  share  value of the
               consideration  to be received by Teltrend  stockholders  might be
               significantly  more  than the  price  per  share  implied  by the
               exchange  ratio  immediately  prior  to the  announcement  of the
               merger;
          o    the  quantitative  analysis of the financial  terms of the merger
               performed by Goldman Sachs, its financial advisor;
          o    the opinion of Goldman Sachs  described below as to the fairness,
               from a financial point of view, of the exchange ratio,  which was
               determined   through   arms-length   negotiations   between   the
               companies;
          o    the  assurance  of  Hambrecht  &  Quist,   Westell's   additional
               financial  advisor,  that,  based on Hambrecht & Quist's  limited
               review of the transaction and certain related  documents,  it had
               identified no  significant  risks not also  identified by Goldman
               Sachs or Westell's management with respect to the merger;
          o    Teltrend's and Westell's respective  businesses,  assets, product
               mixes,   manufacturing  facilities,   liabilities,   managements,
               strategic objectives, and prospects;
          o    the  challenges of combining the  businesses of two  corporations
               the  size of  Westell  and  Teltrend  and the  attendant  risk of
               diverting management resources from other strategic opportunities
               and from operational matters for an extended period of time; and
          o    the  anticipated  impact  of  the  merger  on the  customers  and
               employees of each company.

         The foregoing  discussion of the information and factors considered and
given  weight  by  the  Westell  Board  is not  intended  to be  exhaustive  but
summarizes the material factors considered. The Westell Board did not assign any
relative or specific  weights to the various factors  considered.  Instead,  the
Westell  Board  conducted an overall  analysis of the factors  described  above,
including through discussions with and asking questions of Westell's  management
and legal and financial  advisors.  In considering the factors  described above,
the individual directors may have given different weight to different factors.

         ACCORDINGLY,  THE WESTELL  BOARD HAS  UNANIMOUSLY  APPROVED  THE MERGER
AGREEMENT AND UNANIMOUSLY  RECOMMENDS THAT THE HOLDERS OF WESTELL CLASS A COMMON
STOCK AND CLASS B COMMON  STOCK VOTE FOR APPROVAL OF THE ISSUANCE OF THE WESTELL
CLASS A COMMON STOCK IN THE MERGER AND THE  AMENDMENT  TO WESTELL'S  AMENDED AND
RESTATED  CERTIFICATE  OF  INCORPORATION  TO  INCREASE  TO 85 MILLION  FROM 65.5
MILLION  THE TOTAL  NUMBER OF SHARES OF CLASS A COMMON  STOCK  THAT  WESTELL  IS
AUTHORIZED TO ISSUE.

TELTREND'S REASONS FOR THE MERGER; RECOMMENDATION OF THE TELTREND BOARD

         On December 13, 1999, the Teltrend Board  unanimously  determined  that
the merger  agreement  and the  transactions  contemplated  thereby,  including,
without  limitation,  the merger,  are  advisable  and in the best  interests of
Teltrend and the Teltrend  stockholders and decided to recommend adoption of the
merger agreement to the Teltrend stockholders.

         In  evaluating  the  merger,  the  Teltrend  Board  consulted  with its
management,  financial advisors and legal counsel and gave careful consideration
to a number of factors which supported the board's determinations, including the
following:

          o    the  various  alternatives  to the  merger,  including  remaining
               independent, and the risks associated with those alternatives;
          o    the relative  risks to  Teltrend's  business if the merger is not
               completed;
          o    the results of due  diligence  reviews  conducted  by  Teltrend's
               management,  legal  advisors  and  financial  advisors  examining
               Westell's  business,   operations,   technology  and  competitive
               position;
          o    the fact that Teltrend's  stockholders would have the opportunity
               to  participate  in the  potential  for  growth  of the  combined
               company after the merger,  as the merger is expected to result in
               a combined  company with  greater  financial,  technological  and
               human  resources  to develop new  generations  of  products,  and
               greater marketing resources to develop and promote each company's
               existing products;
          o    the price per share implied by the exchange  ratio in the merger,
               as of the  last  trading  day  prior to the  announcement  of the
               merger,  represented  a premium  of 53% to the  closing  price of
               Teltrend's  common  stock on the last  trading  day  prior to the
               announcement  of the merger,  and a premium of 72% to the average
               closing price of Teltrend's  common stock over the twenty trading
               days prior to the announcement of the merger;
          o    the shares of Westell Class A Common Stock issuable to Teltrend's
               stockholders  in the  merger  will  have a  significantly  larger
               market float and average trading volume upon the merger,  and may
               provide  greater  liquidity,   than  the  Teltrend  common  stock
               currently has;
          o    the fact that the merger would be a tax-free  reorganization  for
               federal  income tax purposes;
          o    Teltrend's  ability  to  terminate  the merger  agreement  if the
               Teltrend  board were presented  with a superior  offer,  upon the
               payment  of a fee of  $7,177,632  to  Westell,  as well as  other
               scenarios  under which  termination is possible,  with or without
               termination fees;
          o    the Teltrend  board of directors'  review with its legal advisors
               of the terms and  conditions  of the merger  agreement and voting
               agreement.  In  particular,   the  board  considered  the  events
               triggering  payment of the termination fee and the limitations on
               Teltrend's  ability to negotiate an alternative  transaction with
               other companies,  and the potential effect these provisions would
               have on Teltrend receiving  alternative  proposals which could be
               superior to the merger;
          o    the opinion of SoundView  Technology Group, Inc. delivered orally
               on December 13, 1999,  and confirmed in writing,  that as of such
               date and subject to assumptions  made and matters  considered and
               limitations  on  the  review  set  forth  in  its  opinion,   the
               consideration  to be  received by  Teltrend  stockholders  in the
               merger was fair to Teltrend  stockholders  from a financial point
               of view; and
          o    the  willingness  of Robert C.  Penny  III and  Melvin J.  Simon,
               individually  and as trustees of the Westell  Technologies,  Inc.
               Voting Trust,  to vote in accordance with the voting by Westell's
               other,   non-affiliated   stockholders   with   respect   to  the
               transactions  contemplated by the merger,  according to the terms
               and conditions of the voting agreement.

<PAGE>


         The Teltrend Board of Directors also  considered a variety of risks and
other potentially  negative factors in its consideration of the merger agreement
and the merger, including the following:

          o    the risk that the  benefits  sought to be  achieved by the merger
               will not be realized;
          o    the fact that  Teltrend's  obligation to pay a termination fee to
               Westell in specified circumstances might deter other parties from
               proposing  an   alternative   transaction   that  might  be  more
               advantageous to Teltrend stockholders;
          o    the risks  associated with a fixed exchange ratio,  including the
               risk that,  because the  exchange  ratio will not be adjusted for
               changes  in the  market  price of either  Westell  Class A Common
               Stock  or  Teltrend  common  stock,  the per  share  value of the
               consideration  to be received by Teltrend  stockholders  might be
               significantly  less  than the  price  per  share  implied  by the
               exchange  ratio  immediately  prior  to the  announcement  of the
               merger;
          o    the  possibility  of management  disruption  associated  with the
               merger, the challenges and costs of integrating the operations of
               the  companies  and the risk that key  management  and  technical
               personnel  might  leave  Teltrend  before or after the  merger is
               completed;
          o    the  expectation  that  current  Westell  stockholders  would own
               approximately  83%  in  voting  power  and  66% in  value  of the
               combined company immediately following the merger, based upon the
               outstanding shares of both companies as of December 10, 1999;
          o    the fact  that  Robert  C.  Penny III and  Melvin  J.  Simon,  as
               stockholders  and as trustees of the Westell  Technologies,  Inc.
               Voting Trust,  are expected to control  approximately  68% of the
               voting power of Westell upon the merger;
          o    the  potential  loss of revenues and business  opportunities  for
               Teltrend  as a  result  of  confusion  in the  marketplace  after
               announcement  of the merger,  or possible  adverse  reactions  by
               existing or  prospective  Teltrend  customers  who  compete  with
               Westell or its affiliates,  and the possible exploitation of such
               issues by Teltrend's and Westell's competitors; and
          o    other   applicable   risks   described   in  this   joint   proxy
               statement/prospectus under "Risk Factors," starting on page I-13.

         The foregoing  discussion of the information and factors considered and
given  weight  by the  Teltrend  Board  is not  intended  to be  exhaustive  but
summarizes  the material  factors  considered.  The Teltrend Board relied on the
experience  and expertise of SoundView  Technology  Group,  Inc.,  its financial
advisor,  for  quantitative  analysis of the financial terms of the merger.  See
"Opinion of Teltrend's  Financial Advisor" beginning on page II-14. The Teltrend
Board did not assign any  relative  or specific  weights to the various  factors
considered.  Instead,  the Teltrend Board  conducted an overall  analysis of the
factors described above, including through discussions with and asking questions
of Teltrend's  management and legal and financial  advisors.  In considering the
factors  described  above,  the  individual  directors may have given  different
weight to different factors.

         FOR THE REASONS  DISCUSSED  ABOVE,  THE TELTREND BOARD HAS  UNANIMOUSLY
APPROVED  AND  DEEMED  ADVISABLE  AND  IN THE  BEST  INTERESTS  OF THE  TELTREND
STOCKHOLDERS  THE MERGER  AGREEMENT AND THE MERGER,  AND UNANIMOUSLY  RECOMMENDS
THAT THE TELTREND  STOCKHOLDERS  VOTE FOR APPROVAL OF THE ADOPTION OF THE MERGER
AGREEMENT.

OPINION AND ADVICE OF WESTELL'S FINANCIAL ADVISORS

OPINION OF GOLDMAN SACHS

         On December 13, 1999,  Goldman Sachs  delivered its oral opinion to the
Board of Directors of Westell that, as of such date, the exchange ratio was fair
from a financial point of view to Westell.  Goldman Sachs subsequently confirmed
its oral opinion by delivery of its written opinion dated December 13, 1999.

         THE FULL TEXT OF THE WRITTEN  OPINION OF GOLDMAN SACHS,  DATED DECEMBER
13, 1999, WHICH SETS FORTH ASSUMPTIONS MADE,  MATTERS CONSIDERED AND LIMITATIONS
ON THE REVIEW UNDERTAKEN IN CONNECTION WITH THE OPINION, IS ATTACHED AS APPENDIX

<PAGE>


B AND IS INCORPORATED BY REFERENCE IN THIS JOINT PROXY STATEMENT/PROSPECTUS. YOU
SHOULD READ THE OPINION IN ITS ENTIRETY.

         In connection  with its opinion,  Goldman Sachs  reviewed,  among other
things:

          o    the merger agreement;
          o    annual reports to stockholders and annual reports on Form 10-K of
               Teltrend  and Westell  for the five  fiscal  years ended July 31,
               1999  and  the  four  fiscal   years   ended   March  31,   1999,
               respectively;
          o    interim  reports to  stockholders  and quarterly  reports on Form
               10-Q of Teltrend and Westell;
          o    other   communications   from   Teltrend  and  Westell  to  their
               respective stockholders; and
          o    internal  financial  analyses  and  forecasts  for  Teltrend  and
               Westell prepared by their respective managements, including costs
               savings and operating  synergies  projected by the  management of
               Westell to result from the merger.

         Goldman  Sachs  also  held  discussions  with  members  of  the  senior
management of Teltrend and Westell  regarding the strategic  rationale  for, and
the  potential  benefits  of,  the  merger  and the  past and  current  business
operations,  financial  condition  and  future  prospects  of  their  respective
companies. In addition, Goldman Sachs:

          o    reviewed the reported price and trading activity for the Teltrend
               common stock and Westell Class A Common Stock;
          o    compared  financial and stock market information for Teltrend and
               Westell  with  similar  information  for  other   publicly-traded
               companies;
          o    reviewed the financial terms of recent  business  combinations in
               the   telecommunications   equipment,   data  communications  and
               networking  industries   specifically  and  in  other  industries
               generally; and
          o    performed  other studies and analyses  Goldman  Sachs  considered
               appropriate.

         Goldman Sachs relied upon the accuracy and  completeness  of all of the
financial  and other  information  reviewed by it and assumed such  accuracy and
completeness  for purposes of rendering  its  opinion.  In that regard,  Goldman
Sachs  assumed,  with the  consent  of the  Westell  Board,  that  the  internal
financial  forecasts  prepared  by the  managements  of  Teltrend  and  Westell,
including any synergies, have been reasonably prepared on a basis reflecting the
best  currently  available  estimates  and judgments of Teltrend and Westell and
that such  forecasts and synergies  will be realized in the amounts and the time
periods  contemplated  thereby.  Goldman  Sachs  did  not  make  an  independent
evaluation or appraisal of the assets and  liabilities of Teltrend or Westell or
any of their  subsidiaries  and was not  furnished  with any such  evaluation or
appraisal. Goldman Sachs also assumed that all material governmental, regulatory
or other  consents and approvals  necessary for the  consummation  of the merger
will be obtained  without  any  adverse  effect on Teltrend or Westell or on the
benefits of the merger.  The advisory services and opinion of Goldman Sachs were
provided for the  information  and assistance of the Westell Board in connection
with its  consideration  of the merger,  and the opinion  does not  constitute a
recommendation  as to how any holder of Westell  Class A Common Stock or Class B
Common Stock should vote with respect to the merger proposals.

         The following is a summary of the material  financial  analyses used by
Goldman Sachs in connection  with  providing its opinion to the Westell Board on
December 13, 1999.

         THE  FOLLOWING  SUMMARIES OF  FINANCIAL  ANALYSES  INCLUDE  INFORMATION
PRESENTED IN TABULAR FORMAT. YOU SHOULD READ THESE TABLES TOGETHER WITH THE TEXT
OF EACH SUMMARY.

         (1) Exchange Ratio History.  Goldman Sachs  calculated the ratio of the
average  market price of Teltrend  common  stock to the average  market price of
Westell Class A Common Stock during  selected  weekly periods ending the week of
December 6, 1999. The results are shown in the following table:


<PAGE>




                      Period                        Average Share Exchange Ratio
                      ------                        ----------------------------
        3 months ending December 9, 1999                       2.33x
        1 year ending December 9, 1999                         2.95x
        3 years ending December 9, 1999                        2.03x

         (2) Public  Market  Comparison.  Goldman  Sachs  compiled  and reviewed
selected  financial  information and calculated certain ratios and public market
multiples  for two groups of publicly  traded  companies  in the  communications
equipment industry.


Group A consisted of:                        Group B consisted of:

        o   ADC Telecommunications, Inc.;      o  Allen Telecom Inc.;
        o   ADTRAN, Inc.;                      o  Andrew Corporation; and
        o   Aware, Inc.;                       o  Tollgrade Communications, Inc.
        o   Copper Mountain Networks, Inc.;
        o   Orckit Communications Ltd.;
        o   Pairgain Technologies, Inc.;
        o   Paradyne Networks Inc.;
        o   Redback Networks Inc.; and
        o   Westell Technologies, Inc.


         The selected  companies  were chosen  because they are  publicly-traded
communications equipment companies with operations that for purposes of analysis
may be considered  similar to Westell or Teltrend.  The selected  companies were
placed into Group A or Group B based on relative  valuation  metrics.  Companies
trading  at  a  multiple  of  levered  market   capitalization   (equity  market
capitalization  plus net debt) to 1999 estimated revenue of 4.0x or greater were
put in Group A. Other  relevant  comparable  companies  were put in Group B. The
multiples  and ratios were  calculated  using the  closing  price for the common
stock of each of the  selected  companies  on December  10, 1999 and,  except as
otherwise indicated below, were based on Institutional  Brokers Estimate System,
or IBES,  estimates,  and published  equity research reports and the most recent
publicly available information.

         Goldman  Sachs  calculated  low, high and median values for each of the
three ratios or multiples set forth below:

          o    The ratio of price to estimated  earnings per share,  or EPS, for
               calendar years 1999 and 2000, respectively;
          o    Levered market  capitalization  as a multiple of revenues for the
               last twelve months ("LTM"),  estimated revenues for calendar year
               1999 and estimated revenues for calendar year 2000, respectively;
          o    Levered  market  capitalization  as a  multiple  of LTM  earnings
               before interest, taxes, depreciation and amortization, or EBITDA,
               for the last 12 months.

         The high,  low and median  multiples  for the two groups of  comparable
companies were applied to the corresponding operating metric for Teltrend, using
Westell management's  estimates of Teltrend's 1999 and 2000 EPS and revenues. On
this basis,  Goldman  Sachs  calculated a range of implied  prices per share for
Teltrend shares and a range of implied exchange ratios, using a $10.75 per share
price for  Westell  shares.  The results of such  analyses  are set forth in the
following table:

         (3) Selected Transaction Analysis.  Goldman Sachs compiled and reviewed
selected   financial   information   for  282  selected   transactions   in  the
communications  equipment  industry  from  1988 to the  present.  Goldman  Sachs
calculated high, low and median values for the selected transactions for each of
the three ratios or multiples set forth below.

          o    The ratio of equity  consideration  paid in each such transaction
               to the acquired  company's LTM and forward calendar year earnings
               for calendar year 1999, respectively;
          o    Levered consideration as a multiple of the acquired company's LTM
               sales; and
          o    The percentage  premium paid to equity holders  calculated  using
               the price paid per share by the acquirer relative to the target's
               price five days prior to announcement.

         The high, low and median multiples for the selected  transactions  were
applied to the  corresponding  value for Teltrend,  using  Westell  management's
estimates of Teltrend's 1999 earnings. On this basis, Goldman Sachs calculated a
range of  implied  prices per share for  Teltrend  shares and a range of implied
exchange ratios,  using a $10.75 per share price for Westell shares. The results
of such analyses are set forth below:

         (4)  Contribution  Analysis.  Goldman Sachs  calculated  the respective
percentage contribution by Teltrend and Westell to the combined company assuming
Westell's fiscal years 1999, 2000 and 2001 estimated  revenue and 2001 estimated
operating  income on a pro forma  basis.  The analysis did not take into account
any  synergies  that may result  from the merger.  In  addition,  Goldman  Sachs
calculated  the pro forma share  ownership of the combined  company  immediately
following the merger,  assuming a 3.30:1  exchange  ratio, in order to determine
the percentages of the combined company that will be owned immediately following
consummation   of  the  merger  by   stockholders   of  Westell  and   Teltrend,
respectively. The results of such analyses are summarized below.


        -----------------------------------------------------------------------
                     Pro Forma Ownership of the Combined Company
                                     (in percent)
        -----------------------------------------------------------------------
        Westell stockholders                                 66.2

        2001                               44.3                   55.7
        -----------------------------------------------------------------------


         (5) Pro  Forma  Merger  Analysis.  Goldman  Sachs  prepared  pro  forma
analyses  of the  financial  impact of the merger for fiscal  years  ended March
1999,  2000,  2001 and 2002 using  estimates  of earnings for those fiscal years
that were provided by Westell management for both Westell and Teltrend.  Goldman
Sachs  compared  the EPS of  Westell  on a  stand-alone  basis to the  estimated
unadjusted and cash EPS (which excludes the effects of goodwill amortization) of
the combined company on a pro forma basis,  both including and not including the
synergies estimated by Westell management to result from the merger. The results
of such  analyses  indicate  that for the fiscal  year ended  March 30, 1999 the
merger would be dilutive on an EPS basis, not including synergies, and accretive
on an EPS basis,  including  synergies,  and on a cash EPS basis, both including
and not including synergies. For the fiscal years ended March 30, 2001 and 2002,
the merger  would be  dilutive on an EPS basis,  both  including  and  excluding
synergies,  but  accretive on a cash EPS basis,  both  including  and  excluding
synergies.

         (6) Discounted Cash Flow Analysis - Teltrend. Goldman Sachs performed a
discounted  cash flow  analysis of the  expected  cash flows of  Teltrend  using
projections from Westell's management under the following two scenarios: (a) not
including  the  synergies  estimated  by Westell  management  to result from the
merger (the "Base Case") and (b) including  the  synergies  estimated by Westell
management  to result  from the merger (the  "Synergies  Case").  Goldman  Sachs
calculated  a net  present  value of  Teltrend's  free cash flows for the fiscal
years 2000 through 2004 using  discount  rates  ranging from 8% to 12%.  Goldman
Sachs  also  calculated  Teltrend's  terminal  values in the year 2004  based on
multiples  ranging from 7x EBITDA to 12x EBITDA.  The terminal  values were then
discounted  to present  value using  discount  rates from 8% to 12%. The implied
values per  Teltrend  share  derived  from such  analysis  ranged from $25.03 to
$44.45 in the Base Case and from $43.36 to $75.71 in the Synergies Case.

         (7)  Discounted  Cash Flow  Analysis  -  Westell.  Goldman  Sachs  also
performed a discounted  cash flow analysis of the expected cash flows of Westell
using  projections  from Westell's  management.  Goldman Sachs  calculated a net
present  value of  Westell's  free cash flows for the fiscal  years 2001 through
2005 using discount rates ranging from 13% to 21%. Goldman Sachs also calculated
Westell's  terminal  values in the year 2005 based on multiples  ranging from 8x
EBITDA to 18x EBITDA.  The terminal values were then discounted to present value

<PAGE>


using  discount  rates from 13% to 21%.  The implied  values per  Westell  share
derived from such analysis ranged from $5.99 to $17.94.

         The  preparation of a fairness  opinion is a complex process and is not
necessarily  susceptible to partial analysis or summary  description.  Selecting
portions of the analyses or of the summary set forth above,  without considering
the  analyses  as a whole,  could  create an  incomplete  view of the  processes
underlying  Goldman Sachs' opinion.  In arriving at its fairness  determination,
Goldman  Sachs  considered  the  results  of all such  analyses.  No  company or
transaction used in the above analyses as a comparison is directly comparable to
Westell or Teltrend or the contemplated merger.

         The analyses were prepared  solely for purposes of providing an opinion
to the  Westell  Board  as to the  fairness  from a  financial  point of view to
Westell  of  the  share  exchange  ratio.  The  analyses  do not  purport  to be
appraisals or necessarily  reflect the prices at which  businesses or securities
actually may be sold.  Analyses  based upon  forecasts of future results are not
necessarily indicative of actual future results, which may be significantly more
or less favorable  than  suggested by such  analyses.  Because such analyses are
inherently  subject to uncertainty,  being based upon numerous factors or events
beyond the control of the parties or their respective advisors, none of Westell,
Teltrend,  Goldman Sachs or any other person  assumes  responsibility  if future
results are materially different from those forecast.

         As described above, Goldman Sachs' opinion to the Westell Board was one
of many  factors  taken into  consideration  by the Westell  Board in making its
determination to approve the merger.  The foregoing  summary does not purport to
be a complete description of the analyses performed by Goldman Sachs.

         Goldman  Sachs,  as  part  of  its  investment  banking  business,   is
continually  engaged in the  valuation of  businesses  and their  securities  in
connection with mergers and acquisitions, negotiated underwritings,  competitive
biddings,  secondary  distributions of listed and unlisted  securities,  private
placements  and  valuations for estate,  corporate and other  purposes.  Goldman
Sachs is  familiar  with  Westell,  having  acted as its  financial  advisor  in
connection with, and having participated in certain of the negotiations  leading
to, the  merger  agreement.  Goldman  Sachs  provides a full range of  financial
advisory  and  securities  services  and,  in the course of its  normal  trading
activities,  may from  time to time  effect  transactions  and hold  securities,
including derivative securities,  of Westell or Teltrend for its own account and
for the accounts of customers.

         In addition,  Goldman Sachs has been informed that SoundView Technology
Group,  Inc. has acted as financial  advisor to Teltrend in connection  with the
merger.  SoundView  and Wit Capital  Group,  Inc. have entered into an agreement
pursuant to which Wit will  acquire  SoundView.  Goldman  Sachs  currently  owns
approximately  16.5%  of the  outstanding  shares  of  common  stock  of Wit and
warrants  to  acquire  additional  shares  of  common  stock  of Wit  which,  if
exercised,  would  result in Goldman  Sachs  owning  approximately  24.7% of the
outstanding shares of common stock of Wit.

         Pursuant to a letter agreement dated September 8, 1999, Westell engaged
Goldman  Sachs to act as its financial  advisor in connection  with the possible
acquisition by Westell or any of its affiliates of all or a portion of the stock
or assets of Teltrend.  Pursuant to the terms of this letter agreement,  Westell
has agreed to pay Goldman  Sachs a  transaction  fee based on the outcome of the
merger as follows:

          o    if the merger is consummated, Goldman Sachs will receive a fee of
               $2.3 million; or
          o    if the  merger is not  consummated  and  pursuant  to the  merger
               agreement  Westell  receives  a payment  in  connection  with the
               termination of the merger  agreement or the failure to consummate
               the merger, Goldman Sachs will receive a fee of $1.0 million.

         Westell also has agreed to reimburse  Goldman Sachs for its  reasonable
out-of-pocket  expenses,  including  attorneys'  fees, and to indemnify  Goldman
Sachs against  certain  liabilities,  including  certain  liabilities  under the
federal securities laws.

ADVICE OF HAMBRECHT & QUIST

         In addition  engaging Goldman Sachs, the Westell Board also engaged the
services of  Hambrecht & Quist LLC to provide  general  advisory  services  with
respect to the merger.  Hambrecht & Quist reviewed the merger agreement, all the
material presented to the Westell Board by Goldman Sachs, as well as certain due
diligence materials prepared by Westell's management.  In addition,  Hambrecht &
Quist had several  conversations with the Westell Board and Westell's management
regarding the transaction,  the negotiation process and general financial market
conditions.  As a result of this limited review, on December 13, 1999, Hambrecht
& Quist orally  advised the Westell Board that it had  identified no significant
risks not also identified by Goldman Sachs or Westell's  management with respect
to the merger.  The Westell Board did not retain Hambrecht & Quist to deliver an
opinion  with regard to its  general  advice or the  fairness,  from a financial
point of view, of the exchange ratio,  and Hambrecht & Quist did not prepare any
such opinion.

         The  advisory  services  of  Hambrecht  & Quist were  provided  for the
information  and  assistance  of  the  Westell  Board  in  connection  with  its
consideration of the merger, and such does not constitute a recommendation as to
how any holder of Westell  Class A Common  Stock or Class B Common  Stock should
vote with  respect to the merger  proposals.  As  described  above,  Hambrecht &
Quist's  advice  to the  Westell  Board  was  one of  many  factors  taken  into
consideration  by the Westell Board in making its  determination  to approve the
merger.

         Hambrecht  & Quist,  as part of its  investment  banking  business,  is
continually  engaged in the  valuation of  businesses  and their  securities  in
connection with mergers and acquisitions, negotiated underwritings,  competitive
biddings,  secondary  distributions of listed and unlisted  securities,  private
placements and valuations for estate, corporate and other purposes.  Hambrecht &
Quist is familiar with Westell, having acted as its general financial advisor in
connection with the merger agreement. Hambrecht & Quist provides a full range of
financial  advisory  and  securities  services  and, in the course of its normal
trading  activities,  may  from  time  to  time  effect  transactions  and  hold
securities,  including derivative securities, of Westell or Teltrend for its own
account and for the accounts of customers.

         Pursuant to a letter  agreement dated August 15, 1999,  Westell engaged
Hambrecht & Quist to act as its secondary  financial  advisor in connection with
the possible acquisition by Westell or any of its affiliates of all or a portion
of the stock or assets of Teltrend, providing general guidance and advice to the
Westell  Board,  but not  rendering  an opinion  regarding  the  fairness of the
ultimate consideration to be paid by Westell in such a transaction.  Pursuant to
the terms of this letter  agreement,  Westell  has agreed to pay to  Hambrecht &
Quist a fee of $225,000 upon the  effectiveness of the merger.  Westell also has
agreed to reimburse Hambrecht & Quist for its reasonable out-of-pocket expenses,
including  attorneys'  fees, and to indemnify  Hambrecht & Quist against certain
liabilities, including certain liabilities under the federal securities laws.

OPINION OF TELTREND'S FINANCIAL ADVISOR

         SoundView  Technology Group, Inc. was retained by the Teltrend Board to
render an opinion as to whether the  exchange  ratio to be offered in the merger
is fair, from a financial point of view, to the Teltrend stockholders.

         On December 13, 1999,  SoundView  delivered its opinion to the Teltrend
Board  that,  as of such date,  based upon the facts and  circumstances  as they
existed  at  that  time,  and  subject  to  certain  assumptions  made,  matters
considered  and limits of review set forth  therein,  the  exchange  ratio to be
offered in the merger is fair,  from a financial  point of view to the  Teltrend
stockholders.

         The full text of the written  opinion of SoundView,  dated December 13,
1999,  which sets forth,  among other  things,  the  assumptions  made,  matters
considered,  and  the  scope  and  limitations  of  the  review  undertaken  and
procedures  followed by  SoundView  in  rendering  its  opinion,  is included in
Appendix  C to this joint  proxy  statement/prospectus.  SoundView's  opinion is
directed only to the fairness,  from a financial  point of view, to the Teltrend
stockholders  of the  exchange  ratio to be offered in the  merger.  SoundView's
opinion  was  delivered  for the use and  benefit of the  Teltrend  Board in its
consideration  of the merger and is not intended to be and does not constitute a
recommendation  to any Teltrend  stockholder as to how such  stockholder  should
vote with  respect  to the  proposed  merger.  The  summary  of the  opinion  of
SoundView  set forth below is  qualified  by  reference  to the full text of the
opinion. Teltrend stockholders are urged to read this opinion in its entirety.


<PAGE>


         In  connection  with  rendering  its  opinion,  SoundView,  among other
things:

          o    reviewed the draft  agreement  and plan of merger dated  December
               13, 1999 and the specific terms of the merger set forth therein;
          o    reviewed the draft voting agreement dated December 13, 1999;
          o    reviewed Teltrend's  financial and operating  information for the
               two-year  period ended July 31, 1999 and the  three-month  period
               ended October 30, 1999;
          o    reviewed  Westell's  financial and operating  information for the
               two year period  ended March 31,  1999 and the  six-month  period
               ended September 30, 1999;
          o    reviewed certain  information  regarding the private placement by
               Westell  of 6%  subordinated  convertible  debentures  and  stock
               purchase warrants to Capital Ventures International, Castle Creek
               Technology Partners LLC, and Marshall Capital Management, Inc.;
          o    reviewed certain  financial and operating  information  regarding
               the business,  operations  and prospects of Teltrend and Westell,
               including  forecasts  and  projections,  provided  to it  by  the
               managements of Teltrend and Westell, respectively;
          o    reviewed  certain  publicly  available   information   concerning
               certain other companies which it deemed to be reasonably  similar
               to Teltrend  and  Westell and the trading  markets for certain of
               such companies' securities;
          o    reviewed  the  financial  terms of  certain  recent  mergers  and
               acquisitions which it deemed relevant;
          o    conducted  discussions with certain members of senior  management
               of Teltrend and Westell  concerning their  respective  businesses
               and operations,  assets, present conditions and future prospects;
               and
          o    performed  such  other  analyses,  examinations  and  procedures,
               reviewed such other agreements and documents, and considered such
               other  factors  as  it  deemed,  in  its  sole  judgment,  to  be
               necessary, appropriate or relevant to render its opinion.

         In arriving at its opinion,  SoundView  did not make,  obtain or assume
any responsibility for any independent evaluation or appraisal of the properties
and  facilities or of the assets and  liabilities  (contingent  or otherwise) of
either Teltrend or Westell.  SoundView  assumed and relied upon the accuracy and
completeness  of the  financial and other  information  supplied to or otherwise
used by it in arriving at its  opinion,  and did not  attempt  independently  to
verify,  or undertake any  obligation  to verify,  such  information.  SoundView
further  relied upon the  assurances of the  managements of Teltrend and Westell
that  they  were  not  aware of any  facts  that  would  make  such  information
inaccurate or misleading. In addition,  SoundView assumed that the forecasts and
projections  provided  to  it by  Westell  and  Teltrend  represented  the  best
currently   available  estimates  and  judgments  of  Westell's  and  Teltrend's
managements  as to the future  financial  condition and results of operations of
Westell  and  Teltrend,  respectively,  and  assumed  that  such  forecasts  and
projections were reasonably prepared based on such currently available estimates
and judgments.  SoundView assumed no responsibility for and expressed no view as
to such forecasts and projections or the assumptions on which they were based.

         SoundView  also took into account its  assessment of general  economic,
market and financial conditions and its experience in similar  transactions,  as
well as its  experience  in  securities  valuation  in  general.  Its opinion is
necessarily  based upon  conditions as they existed and could be evaluated as of
December 13, 1999.

         SoundView did not express any view as to the price at which  Teltrend's
stock  will trade  prior to the  closing  of the  merger,  or the price at which
Westell's  stock will trade prior to or subsequent to the closing of the merger.
Its opinion did not  constitute  a  recommendation  of the merger over any other
alternative  transactions  which may have been available to Teltrend and did not
address the underlying  business  decision of the Teltrend Board to proceed with
or effect the merger.

         The  following  is a  brief  summary  of the  material  aspects  of the
analyses performed by SoundView in connection with rendering its opinion.

         ANALYSES RELATING TO TELTREND


<PAGE>


         Analysis  of  Selected  Comparable  Publicly  Traded  Companies.  Using
publicly available information, SoundView compared certain financial, market and
operating information of selected publicly traded  telecommunications  equipment
manufacturers that were, in SoundView's judgment,  similar to Teltrend. For each
of the selected companies,  SoundView  calculated a multiple of enterprise value
to calendar 1998 and projected calendar 1999 and 2000 revenues. Enterprise value
was calculated by adding net debt to the company's  market  capitalization.  Net
debt was calculated by subtracting  cash and cash  equivalents  from total debt.
Companies  analyzed by SoundView in connection  with this analysis  included ADC
Telecommunications,   Inc.,  ADTRAN,   Inc.,  Larscom   Incorporated,   PairGain
Technologies, Inc. and Tollgrade Communications,  Inc. The table below shows the
results of such analysis.

Stock on December 10, 1999.

         Comparable Transaction Analysis.  Using publicly available information,
SoundView   analyzed  the  purchase   prices  and  multiples  paid  in  selected
acquisitions of telecommunications  equipment manufacturers that, in SoundView's
judgment, were comparable to the business of Teltrend.  However, SoundView noted
that none of such acquisitions took place under market conditions or competitive
conditions or circumstances  that are directly  comparable to a merger as of the
date of SoundView's opinion and that, accordingly, qualitative judgments must be
made concerning the difference between the characteristics of these transactions
and other factors and issues which would affect the price an acquiror is willing
to pay in an acquisition. For each of the selected targets, SoundView calculated
a multiple of enterprise  value to LTM revenue.  Enterprise value was calculated
by  adding  net  debt to the  company's  market  capitalization.  Net  debt  was
calculated by subtracting cash and cash  equivalents from total debt.  SoundView
analyzed 19  transactions  that were  completed  between  November  21, 1994 and
November  21,  1999,  and the table below  shows the  results of such  analysis.

Stock on December 10, 1999.

         Premiums  Paid  Analysis.   SoundView   reviewed   publicly   available
information  for  selected  completed  stock-for-stock  merger  and  acquisition
transactions,  which were announced  between  November 21, 1996 and November 21,
1999,  with a value of $50 million to $500  million  and in which the  acquiring
company purchased greater than 50% of a public target.

         SoundView performed its analysis on 424 transactions that satisfied the
criteria,  and the table below shows a comparison of those  premiums paid to the
premium that would be paid to Teltrend stockholders based upon the implied value
payable in the  transaction.  The premium  calculations  for Teltrend  stock are
based upon the value of Westell Class A Common Stock on December 10, 1999.

         Discounted  Cash Flow  Analysis.  SoundView  conducted  an  unleveraged
discounted  cash flow analysis  based upon  financial  information  for Teltrend
provided by its management.  SoundView  calculated a range of net present values
of the  projected  unleveraged  free cash flows in the  forecast  using  various
discount rates reflecting  weighted average costs of capital in the range of 15%
to 20%.  SoundView then combined such values with the terminal values calculated
by multiplying  projected revenue for the year 2004 by a range of exit multiples
from 0.5 to 1.5 times and using the same  discount  rates as those  utilized for
unleveraged  free cash flows to obtain ranges of implied total  enterprise value
for Teltrend.  The net present  value of free cash flow,  when combined with the



<PAGE>



terminal values, yielded an implied total enterprise value in the range of $96.1
million to $249.3  million.  In order to derive  implied  equity value per share
ranges for Teltrend,  SoundView subtracted the estimated net debt of Teltrend as
of October  31, 1999 from the implied  total  enterprise  values and divided the
result  by the fully  diluted  shares  outstanding  for  Teltrend.  Net debt was
calculated by subtracting cash and cash equivalents from total debt. The implied
equity  value per share for  Teltrend  was in the range of $18.45 to $41.25  per
share.

         ANALYSES RELATING TO WESTELL

         Analysis  of  Selected  Comparable  Publicly  Traded  Companies.  Using
publicly available information, SoundView analyzed certain financial, market and
operating  information of selected  publicly traded  companies in the two market
segments  where  Westell  operates.   These  segments  are  asymmetric   digital
subscriber  line (ADSL)  products and  telecommunications  equipment.  Companies
analyzed  by  SoundView  in the  ADSL  industry  included  Aware,  Inc.,  Orckit
Communications  Ltd.  and  Paradyne  Networks,  Inc.  For  each of the  selected
companies,  SoundView calculated enterprise value as a multiple of calendar 1998
and projected  calendar 1999 and 2000 revenues.  Enterprise value was calculated
by  adding  net  debt to the  company's  market  capitalization.  Net  debt  was
calculated by subtracting  cash and cash  equivalents from total debt. The table
below shows the results of such analysis.

2000 revenue).

         Companies  analyzed by  SoundView in the  telecommunications  equipment
market analysis included ADC  Telecommunications,  Inc.,  ADTRAN,  Inc., Larscom
Incorporated, PairGain Technologies, Inc. and Tollgrade Communications, Inc. For
each of the  selected  companies,  SoundView  calculated  enterprise  value as a
multiple of 1998 and  projected  1999 and 2000  revenues.  Enterprise  value was
calculated by adding net debt to the company's market  capitalization.  Net debt
was calculated by  subtracting  cash and cash  equivalents  from total debt. The
following table shows the results of such analysis.

*  Revenues  are for the  fiscal  years  ended  March  31,  1999  (shown as 1998
revenue),  2000 (shown as projected  1999  revenue) and 2001 (shown as projected
2000 revenue).

         Discounted  Cash Flow  Analysis.  SoundView  conducted  an  unleveraged
discounted  cash flow  analysis  based upon  financial  information  for Westell
provided by its management.  SoundView  calculated a range of net present values
of the  projected  unleveraged  free cash flows in the  forecast  using  various
discount rates reflecting  weighted average costs of capital in the range of 15%
to 25%.  SoundView then combined such values with the terminal values calculated
by multiplying  projected revenue for the year 2004 by a range of exit multiples
from 2.0 to 4.0 times and using the same  discount  rates as those  utilized for
unleveraged  free cash flows to obtain ranges of implied total  enterprise value
for Westell.  The net present  value of free cash flow,  when  combined with the
terminal value, yielded an implied total enterprise value in the range of $300.8
million to $778.1  million.  In order to derive  implied  equity value per share
ranges for Westell, SoundView subtracted the estimated net debt of Westell as of
September  30, 1999 from the  implied  total  enterprise  values and divided the
result by the fully diluted shares  outstanding for Westell.  The implied equity
value per share for Westell was in the range of $6.98 to $17.70 per share.

         In  arriving  at its opinion  and in  discussing  its opinion  with the
Teltrend  Board,  SoundView  performed  various  financial  analyses.  While the
foregoing  summary  describes  all material  analyses and factors  considered by
SoundView  in  rendering  its  opinion,  such  summary  does not purport to be a
complete  description  of  SoundView's  analyses.  SoundView  believes  that its
analyses and  summaries  should be  considered  as a whole,  and that  selecting
portions of its analyses or the factors  considered by it,  without  considering
all  factors  and  analyses,  could  create  a  misleading  view of the  process
underlying  its  opinion.  The  preparation  of a fairness  opinion is a complex
process  and is not  necessarily  susceptible  to partial  analyses  and summary
description. In performing its analyses,  SoundView considered general economic,
market and financial conditions and other matters,  many of which are beyond the
control of Teltrend and Westell.  The  analyses  performed by SoundView  are not
necessarily  indicative  of  actual  values  or  future  results,  which  may be
significantly  more or less  favorable  than those  suggested by such  analyses.
Accordingly,  such analyses and estimates are inherently  subject to substantial
uncertainty.

         SoundView is a nationally  recognized  investment banking firm. As part
of its  investment  banking  services,  SoundView is  frequently  engaged in the
valuation of businesses  and their  securities  in  connection  with mergers and
acquisitions,  underwritings,  secondary  distributions  of securities,  private
placements and valuations for estate,  corporate and other  purposes.  SoundView
was retained by the Teltrend Board to act as its financial advisor in connection
with the merger  based upon  SoundView's  experience  as a financial  advisor in
mergers  and   acquisitions  as  well  as  SoundView's   familiarity   with  the
telecommunications equipment manufacturing industry.

         Except  as  described  above,   SoundView  has  not  rendered  material
financial  advisory  or  investment  banking  services to Teltrend or to Westell
during the last three years. In the ordinary  course of its business,  SoundView
may actively trade in the equity  securities of Teltrend and Westell for its own
account and for the accounts of its customers and, accordingly,  may at any time
hold a long or short position in such securities.

         Pursuant to the terms of its engagement letter with SoundView, Teltrend
has agreed to pay  SoundView a cash fee at the  closing of the merger  equal to:
(1) 1.50% of the first $40 million of  consideration  paid by Westell at closing
(defined as gross value of cash and the fair market value of all other  property
paid by Westell in connection  with the merger);  plus (2) 1.00% of the next $40
million of consideration; plus (3) 0.05% of any consideration over $80 million.


<PAGE>


         In  addition,  Teltrend  has  agreed  to  reimburse  SoundView  for all
reasonable  expenses  incurred by it in  connection  with the merger,  including
reasonable  professional  fees and  disbursements.  Teltrend  has also agreed to
indemnify   SoundView  against  certain   liabilities  in  connection  with  its
engagement.

VOTING AGREEMENT WITH WESTELL CONTROLLING STOCKHOLDERS

         Concurrently  with the  execution  of the merger  agreement,  Robert C.
Penny III and Melvin J. Simon,  individually  and as  co-trustees of the Westell
Technologies,  Inc. Voting Trust,  entered into an agreement with Teltrend under
which each of them has agreed to vote all of the  capital  stock of Westell  for
which he has the power to vote in favor of the merger proposals if a majority of
the votes  held by  Westell's  public  stockholders  are voted in favor of these
proposals.  For purposes of the voting agreement,  Westell's public stockholders
include all holders of Westell  Class A Common Stock,  other than Messrs.  Penny
and Simon and  members  of their  families  and any  officers  or  directors  of
Westell.

         While the  co-trustees  are  obligated  to vote in favor of the  merger
proposals if a majority of Westell's  public  stockholders  so vote,  the voting
agreement does not prevent or prohibit the co-trustees from also voting in favor
of the proposals even if a majority of Westell's public  stockholders reject the
proposals. The co-trustees have indicated their current intention to vote as the
majority of Westell's  non-affiliated,  public stockholders vote with respect to
the proposals.

         Messrs.  Penny and Simon,  as co-trustees of the Westell  Technologies,
Inc.  Voting  Trust,  beneficially  own  approximately  80% of the voting  power
entitled to vote at the  Westell  special  meeting.  The  affirmative  vote of a
majority of the total  votes cast is required to approve the  issuance of shares
of Westell's  Class A Common Stock in the merger and the  affirmative  vote of a
majority of the total votes  outstanding is required to approve the amendment to
Westell's Certificate of Incorporation.

         Until the merger is  completed or the merger  agreement is  terminated,
the voting agreement only allows the co-trustees to transfer shares of Westell's
Class B Common Stock in transactions where:

          o    the Class B Common Stock is  converted  into Class A Common Stock
               which is then sold to unaffiliated third parties; or
          o    the  recipient  of the Class B Common Stock agrees to be bound by
               the terms of the voting agreement.

MATERIAL FEDERAL INCOME TAX CONSEQUENCES

         The following  outlines the material  United States  federal income tax
consequences of the merger and is not a complete  analysis of all tax effects of
the  merger.  The  discussion  does not  address  the effect of state,  local or
non-U.S.  tax laws, or the effect of any U.S.  federal tax laws other than those
pertaining to United States federal income tax.

         Westell  and  Teltrend   intend  that  the  merger  will  constitute  a
"reorganization"  within the meaning of Section  368(a) of the Internal  Revenue
Code of  1986.  As a  reorganization  under  Section  368(a)  of the  Code,  the
following are the material United States federal income tax  consequences of the
merger:

          o    no gain or loss will be recognized by Teltrend,  Westell or Theta
               Acquisition Corp. as a result of the merger;
          o    no gain or loss will be recognized by Teltrend  stockholders upon
               the  conversion  of Teltrend  common stock into shares of Westell
               Class A Common Stock pursuant to the merger,  except with respect
               to cash, if any, received in lieu of fractional shares of Westell
               Class A Common Stock;
          o    the  aggregate  tax basis of the shares of Westell Class A Common
               Stock  received in exchange  for shares of Teltrend  common stock
               pursuant to the merger,  including a fractional  share of Westell
               Class A Common Stock for which cash is received, will be the same
               as the aggregate tax basis of the shares of Teltrend common stock
               exchanged therefor;

<PAGE>

          o    the holding  period of the shares of Westell Class A Common Stock
               received  in the merger will  include  the holding  period of the
               shares of Teltrend common stock exchanged therefor; and
          o    a Teltrend  stockholder who receives cash in lieu of a fractional
               share of Westell Class A Common Stock will recognize gain or loss
               equal to the difference,  if any, between the  stockholder's  tax
               basis in the fractional share and the amount of cash received.

         THE  CONCLUSIONS  EXPRESSED  ABOVE ARE  BASED ON  CURRENT  LAW.  FUTURE
LEGISLATIVE,  ADMINISTRATIVE OR JUDICIAL CHANGES OR  INTERPRETATIONS,  WHICH CAN
APPLY RETROACTIVELY,  COULD AFFECT THE ACCURACY OF THOSE CONCLUSIONS. NO RULINGS
HAVE OR WILL BE SOUGHT FROM THE  INTERNAL  REVENUE  SERVICE  CONCERNING  THE TAX
CONSEQUENCES OF THE MERGER.

         THE DISCUSSION DOES NOT ADDRESS ALL OF THE TAX CONSEQUENCES THAT MAY BE
RELEVANT TO PARTICULAR TAXPAYERS IN LIGHT OF THEIR PERSONAL  CIRCUMSTANCES OR TO
TAXPAYERS  SUBJECT TO SPECIAL  TREATMENT UNDER THE CODE. SUCH TAXPAYERS  INCLUDE
NON-U.S. PERSONS,  INSURANCE COMPANIES,  TAX-EXEMPT ENTITIES,  RETIREMENT PLANS,
DEALERS IN SECURITIES, BANKS AND PERSONS WHO ACQUIRED TELTREND STOCK PURSUANT TO
THE EXERCISE OF EMPLOYEE STOCK OPTIONS OR OTHERWISE AS COMPENSATION.

         BECAUSE  OF THE  COMPLEXITY  OF THE  TAX  LAWS,  AND  BECAUSE  THE  TAX
CONSEQUENCES TO ANY PARTICULAR  TELTREND  STOCKHOLDER MAY BE AFFECTED BY MATTERS
NOT DISCUSSED  ABOVE,  EACH TELTREND  STOCKHOLDER IS URGED TO CONSULT A PERSONAL
TAX ADVISOR WITH RESPECT TO THE SPECIFIC TAX  CONSEQUENCES  OF THE MERGER TO HIM
OR HER TAKING INTO ACCOUNT HIS OR HER OWN  PARTICULAR  CIRCUMSTANCES,  INCLUDING
THE APPLICABILITY AND EFFECT OF STATE,  LOCAL AND NON-U.S.  TAX LAWS, AS WELL AS
OF THE FEDERAL TAX LAWS.

ACCOUNTING TREATMENT

         Westell and Teltrend  anticipate  that the merger will be accounted for
as a purchase. Merger related costs of approximately $5 million will be included
in the determination of the purchase price. See "Westell and Teltrend  Unaudited
Condensed Consolidated Pro Forma Financial Data" beginning on page II-24.

         The unaudited pro forma financial  information  contained in this joint
proxy  statement/prospectus  has been prepared by accounting for the merger as a
purchase.

REGULATORY APPROVALS

         Under the  Hart-Scott-Rodino  Antitrust  Improvements  Act of 1976,  as
amended (the "HSR Act"), and the rules and regulations  promulgated  thereunder,
specified  transactions,  including the merger,  may not be  consummated  unless
certain waiting period requirements have expired or been terminated. Westell and
Teltrend filed their Premerger Notification and Report Forms pursuant to the HSR
Act with the United  States  Department  of Justice  (the  "DOJ") and the United
States Federal Trade  Commission  (the "FTC") on January 3, 2000 and are waiting
for the expiration of the required waiting period. Under the HSR Act, the merger
may not be  consummated  until thirty days  (unless  early  termination  of this
waiting period is granted) after the initial filing or, if the FTC or DOJ issues
a request for additional  information and other documentary  material (a "second
request"),  twenty days after Westell and Teltrend have  substantially  complied
with such a second  request.  If no second  request is made,  the waiting period
will expire on February 2, 2000.

         The FTC and DOJ frequently  scrutinize the legality under the antitrust
laws of  transactions  such as the  merger.  At any time  before  or  after  the
effective time of the merger, the FTC, the DOJ or others could take action under
the antitrust laws with respect to the merger,  including  seeking to enjoin the
consummation of the merger,  to rescind the merger or to require the divestiture
of substantial  assets of Westell or Teltrend.  While the companies believe that
the merger is legal under the antitrust  laws,  there can be no assurance that a
challenge  to the  merger on  antitrust  grounds  will not be made or, if such a
challenge is made, that it would not be successful.

         Under the merger  agreement,  Westell and  Teltrend  have agreed to use
their reasonable  efforts to comply as expeditiously as possible with all lawful
requests of the FTC or the DOJ for additional information and documents and have
agreed  not to extend  the  waiting  period  under the HSR Act or enter into any
agreement  with  the  FTC  or  the  DOJ  not  to  consummate  the   transactions
contemplated  by the merger  agreement  without the each other's  prior  written


<PAGE>



consent.  In addition,  Westell has agreed to  reasonably  consider  taking such
actions  as may be useful in  resolving  any  antitrust  objections  that may be
asserted  with respect to the merger by the FTC, the DOJ or any other federal or
state agency.

NO APPRAISAL RIGHTS

         Neither the  Teltrend  stockholders  nor the Westell  stockholders  are
entitled to appraisal rights under Delaware law in connection with the merger.

RESTRICTIONS ON RESALES BY AFFILIATES

         All shares of Westell  Class A Common Stock to be issued in  connection
with the  merger  have been  registered  under the  Securities  Act of 1933,  as
amended. As a result,  these shares may be traded freely and without restriction
by those  stockholders  not deemed to be  "affiliates"  of Teltrend prior to the
date of the  Teltrend  special  meeting,  as  that  term is  defined  under  the
Securities  Act,  or of Westell  following  the  effective  time of the  merger.
Affiliates  are generally  defined as persons who control,  are controlled by or
are under  common  control  with  Teltrend at the time of the  Teltrend  special
meeting,  or Westell  following the effective  time,  and include  directors and
executive officers of Teltrend or Westell.

         This joint  proxy  statement/prospectus  does not cover any  resales of
Westell Class A Common Stock to be received by these affiliates and no person is
authorized  to  make  any  use  of  this  joint  proxy  statement/prospectus  in
connection  with any such resale.  As a result,  any  subsequent  transfer by an
affiliate of Teltrend must be one permitted by the resale provisions of Rule 145
under the  Securities  Act, or Rule 144 under the  Securities Act in the case of
such persons who become affiliates of Westell,  or as otherwise  permitted under
the Securities Act. These  restrictions  are expected to apply to the directors,
executive  officers and holders of 10% or more of the Teltrend  common stock, as
well as to certain other related  individuals or entities.  The merger agreement
requires  Teltrend to obtain from its executive  officers and directors,  and to
use its reasonable best efforts to obtain from its other  affiliates,  a written
agreement  to the effect that such  persons  will not offer,  sell or  otherwise
dispose  of any  shares of Westell  Class A Common  Stock  issued to them in the
merger,  except as  permitted  by the  Securities  Act or the rules  promulgated
thereunder.

                              WESTELL AND TELTREND
            UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL DATA


         The following  unaudited  pro forma  condensed  consolidated  financial
statements give effect to the proposed  acquisition of Teltrend by Westell under
the purchase method of accounting as defined in APB Opinion No. 16.

         When  reviewing the following  pro forma  information,  you should note
that:

          o    the  pro  forma  condensed   consolidated  balance  sheet  as  of
               September  30,  1999  assumes  that  the  merger  took  place  on
               September  30, 1999 and  combines  Westell's  September  30, 1999
               unaudited  consolidated balance sheet with Teltrend's October 30,
               1999 unaudited consolidated balance sheet;

          o    the pro forma condensed  consolidated statement of operations for
               the fiscal  year ended  March 31,  1999  assumes  the merger took
               place as of April 1, 1998,  and combines  Westell's  consolidated
               statement of operations  for its fiscal year ended March 31, 1999
               with Teltrend's  unaudited  consolidated  statement of operations
               for the comparable twelve month period ending May 1, 1999; and

          o    the pro forma condensed  consolidated statement of operations for
               the six month  period ended  September  30, 1999 assumes that the
               merger took place as of April 1, 1999, and combines the unaudited
               consolidated statement of operations of Westell for the six month
               period  ending  September  30,  1999  with  Teltrend's  unaudited
               consolidated statement of operations for the comparable six month
               period ending October 30, 1999.

         The unaudited pro forma condensed consolidated financial data have been
included for illustrative purposes only, and do not reflect any cost savings and
other synergies anticipated by Westell's management as a result of the merger or
any nonrecurring charges directly  attributable to the merger. The unaudited pro
forma condensed  consolidated  financial data are not necessarily  indicative of
the results of operations or financial position that would have occurred had the
merger  been  completed  on  the  dates  indicated,  nor  are  they  necessarily
indicative  of  future  results  of  operations  or  financial  position  of the
consolidated company.

         The purchase price  reflected in the  accompanying  pro forma condensed
consolidated  financial  data has been  calculated  based upon an estimated fair
market  value of  Westell's  Class A Common Stock of $ 11.16 per share which was
the average  high/low  on January  14,  2000.  The  effects  resulting  from any
differences  in the final  purchase  price  may  differ  significantly  from the
estimate used herein,  and changes in the fair market value of the Westell Class
A Common Stock  through the date of  consummation  of the merger will affect the
purchase  price to be  allocated.  For example,  every $1 increase in the market
price of  Westell's  Class A Common  Stock  would  result  in a  purchase  price
increase of approximately $22.2 million and a goodwill increase of approximately
$22.2 million,  and would decrease  annual  earnings per share by  approximately
$.02 per share after the merger.

         The  acquired  assets and  liabilities  of  Teltrend  are stated in the
accompanying  pro forma condensed  consolidated  financial  statements at values
representing  a  preliminary  allocation  of  the  purchase  price.  Westell  is
currently in the process of obtaining valuations for the tangible and intangible
assets of Teltrend.  The effects  resulting  from any  differences  in the final
allocation  of the purchase  price may differ  significantly  from the estimates
used herein.

         The  accompanying pro forma  information  should be read in conjunction
with the historical  financial statements and related notes for both Westell and
Teltrend,  which are included in their annual and quarterly reports on file with
the   SEC   and  are   incorporated   by   reference   in   this   joint   proxy
statement/prospectus. See "Where You Can Find More Information" on page VI-1.

                      CONDENSED CONSOLIDATED FINANCIAL DATA

NOTE 1 -- PURCHASE PRICE ALLOCATION

         Westell  estimates that the purchase price for the acquisition  will be
approximately  $243.0  million,  based upon an  estimated  fair market  value of
Westell's  Class A Common  Stock of  $11.16  per  share  which  was the  average
high/low on January 14,  2000,  and the  issuance  of 19.159  million  shares of
Westell  Class A Common  Stock in  exchange  for all shares of  Teltrend  common
stock,  plus the fair market  value of the 3.1  million  Westell  stock  options
issued in exchange  for the  outstanding  Teltrend  stock  options.  The effects
resulting  from  any   differences  in  the  final  purchase  price  may  differ
significantly  from the  estimate  used  herein,  and changes in the fair market
value of the Westell  Class A Common Stock through the date of  consummation  of
the merger will affect the purchase price to be allocated. For example, every $1
increase in the market price of Westell's Class A Common Stock would result in a
purchase price increase of approximately  $22.2 million and a goodwill  increase
of approximately $22.2 million,  and would decrease annual earnings per share by
approximately $.02 per share after the merger.

      The  acquired  assets  and  liabilities  of  Teltrend  are  stated  in the
accompanying  pro forma condensed  consolidated  financial  statements at values
representing  a  preliminary  allocation  of  the  purchase  price.  Westell  is
currently in the process of obtaining valuations for the tangible and intangible
assets of Teltrend.  The effects  resulting  from any  differences  in the final
allocation  of the purchase  price may differ  significantly  from the estimates
used herein.

      Total purchase  consideration  and allocation of increase in basis used in
the preparation of these statements was computed as follows:

NOTE 2 -- PRO FORMA ADJUSTMENTS

         Certain pro forma adjustments have been made to the historical  amounts
in the unaudited pro forma condensed consolidated financial data:

a)    Total costs  associated with the merger are estimated to be  approximately
      $5.0  million.  Costs to be incurred by Westell and Teltrend in connection
      with the merger include investment  banking,  legal,  accounting and other
      related fees,  and have been reflected in the  accompanying  unaudited pro
      forma condensed consolidated balance sheet as a reduction to cash.

b)    Reflects  (i) the  issuance of 19.159  million  shares of Westell  Class A
      Common  Stock in exchange  for all shares of Teltrend  common  stock based
      upon an exchange  ratio of 3.3 shares of Westell  Class A Common Stock for

<PAGE>


      each share of Teltrend common stock at an estimated fair market value of $
      11.16 per share of Westell  Class A Common  Stock and (ii) the fair market
      value of 3.1 million  Westell  stock  options  issued in exchange  for the
      outstanding  Teltrend  stock  options.  Also reflects the  elimination  of
      Teltrend equity accounts.

c)   Adjustment to record inventory and property and equipment to estimated fair
     market value, less selling costs.

d)    Excess  of  purchase  price   consideration  over  fair  market  value  of
      identifiable tangible and intangible assets.

e)   Estimated  severance costs that will be accrued at the acquisition date and
     paid over the following year.

f)   Additional  depreciation  as a  result  of the  increase  of  property  and
     equipment to fair market value.

g)   Amortization of goodwill on a straight-line basis over a 20 year life.

h)   Elimination of tax provision  recorded due to the combined entity operating
     at a pro forma loss. All tax benefit is offset by a valuation  allowance in
     pro forma analysis.

i)   The  calculation of weighted  average common and common  equivalent  shares
     assumes an exchange ratio of 3.3 shares of Westell Class A Common Stock for
     each share of Teltrend common stock.  Common  equivalent  shares consist of
     dilutive  shares  issuable upon the exercise of stock options and have been
     excluded from the calculation, as their effect would be anti-dilutive.

          INTERESTS OF TELTREND'S DIRECTORS AND OFFICERS IN THE MERGER

         In considering the recommendation of the Teltrend Board with respect to
the merger agreement, Teltrend stockholders should be aware that certain members
of Teltrend's management and the Teltrend Board may have interests in the merger
that  are  different  from,  or  in  addition  to,  the  interests  of  Teltrend
stockholders  generally,  and which may create potential  conflicts of interest.
The Teltrend Board was aware of, and considered,  the interests of its directors
and officers when it approved the merger agreement and the merger.

TELTREND SEVERANCE PLAN

         The merger agreement provides that Westell will assume, and (subject to
Westell's  right to thereafter  amend,  modify or terminate the policy)  Westell
will  thereafter  pay,  perform  and  discharge  when  due,  all  of  Teltrend's
obligations  under Teltrend's  Executive  Officer Severance Plan with respect to
the individuals who participate  therein.  The following  executive  officers of
Teltrend currently participate in the severance policy:


          o    Howard L, Kirby, Jr.          o    Michael S. Grzeskowiak
          o    Douglas P. Hoffmeyer          o    Theodor A. Maxeiner
          o    Laurence L. Sheets            o    Micahael A. Samocki
          o    Jack C. Parker                o    Janice Lollini
          o    Steven R. Snow                o    Michael Burgess
          o    Gilbert H. Hosie

         The  severance  policy  provides  for the payment of certain  severance
amounts to the participants if they are involuntarily  terminated from Teltrend.
Involuntary termination includes the participant's  resignation or retirement as
a result of a change of control of Teltrend if such resignation or retirement:

          o    is requested or required by the  acquiring  entity as a condition
               to the change of control; or
          o    occurs  within  one  year  of the  completion  of the  change  of
               control.

         Notwithstanding those provisions, however, no severance will be paid to
participants  who  accept  employment,  or refuse  comparable  employment,  with
Teltrend or the acquiring company in a change in control.

         Severance  amounts to be paid to the participants  will be based on the
participant's  annual  base  salary  in  effect  on the date of  termination  of
employment and will vary depending upon his or her position with Teltrend at the
time of the termination  and whether or not the termination  follows a change of
control, as follows. Ten years' service is the maximum period available.

<TABLE>


         Executive                       Standard Termination                           Change-in-Control
         ---------                       --------------------                           -----------------
<S>                          <C>                                           <C>
CEO                          2.4 months base pay for each year of service  4.8 months base pay for each year of service
Senior Vice President        1.8 months base pay for each year of service  3.6 months base pay for each year of service
Vice President               1.2 months base pay for each year of service  2.4 months base pay for each year of service
Assistant Vice President     0.6 months base pay for each year of service  1.2 months base pay for each year of service

</TABLE>

         In addition to the base salary amounts,  the participants  will receive
the same  life,  health and  disability  plan  participation  to which they were
entitled as an employee immediately before the termination.

         Participants who are eligible to receive  severance  payments under the
policy may also request that  Teltrend  amend their stock  options to extend the
period during which the option will vest and be exercisable during the severance
period.  Pursuant to  Teltrend's  stock option  plans,  the vesting of all stock
options held by the  participants  in the severance  policy will accelerate upon
the merger.  Teltrend and Westell have agreed that, prior to the consummation of
the merger,  Teltrend will amend the stock options held by the  participants  to
permit an extension of the time during which the options may be exercised if the
participant becomes so entitled pursuant to the severance policy.

<PAGE>



         The  severance  policy  provides  that,  while it may be  terminated or
amended at any time,  no such  termination  or amendment may reduce or adversely
affect the severance of any participant  whose employment  terminates within two
years of the policy's termination or amendment.

         Neither  Westell  nor  Teltrend  has  determined  whether  any  of  the
above-named  executives who participate in the severance  policy will be offered
comparable employment following the effective time of the merger.  Assuming that
all such executives are terminated or are not offered comparable  employment and
resign,  Westell  will pay to such  executive  officers an  aggregate  severance
payment estimated to be approximately $3.2 million.

TELTREND STOCK OPTION PLANS

         In the merger agreement,  Westell and Teltrend have each agreed to take
all actions necessary to cause each option to purchase shares of Teltrend common
stock which is unexpired and  unexercised as of the merger  effective time to be
automatically  converted at the effective  time into an option (1) to purchase a
number of shares of Westell  Class A Common  Stock equal to the number of shares
of Teltrend common stock subject to the option  multiplied by the exchange ratio
of 3.3,  which is (2) at an exercise price per share equal to the exercise price
in effect under the option  immediately  prior to the effective  time divided by
the exchange ratio.  The date of grant of each converted option will be the date
on which  the  corresponding  Teltrend  option  was  granted.  Each  option,  as
converted,  will  otherwise be subject to the same terms and  conditions  as the
corresponding Teltrend option, except that:

          o    if the applicable  Teltrend option  provides for  acceleration of
               vesting upon the merger,  the converted  option will be so vested
               following the merger; and
          o    the terms of Teltrend options  outstanding  under Teltrend's 1997
               Non-Employee  Director  Stock Option Plan will be amended so that
               the options may be exercised for longer  periods than  previously
               provided, as follows:
               o    with respect to those  Teltrend  directors who do not become
                    directors of Westell following the merger,  until six months
                    following the effective  time of the merger,  or the date on
                    which the options expire (whichever is earlier), and
               o    with  respect  to  Howard  L.  Kirby,  Jr.  and  Bernard  F.
                    Sergesketter,  Teltrend  directors who will become directors
                    of Westell following the merger, until 90 days following the
                    date  on  which  such  person  ceases  to be a  director  of
                    Westell,  or the date on which the options expire (whichever
                    is earlier).

         Substantially  all of  Teltrend's  stock  options  will  vest  upon the
consummation of the merger.  With respect to the following executive officers of
Teltrend:  Howard L. Kirby, Jr., Steven R. Snow,  Douglas P. Hoffmeyer,  Jack C.
Parker,  Michael S. Grzeskowiak,  Gilbert H. Hosie,  Laurence L. Sheets,  Janice
Lollini, Theodor A. Maxeiner, Michael A. Samocki and Michael Burgess, options to
acquire an aggregate of  approximately  167,575 shares of Teltrend  common stock
will vest upon the merger. With respect to the following  non-employee directors
of Teltrend:  Frank T. Cary,  Harry Crutcher,  III,  William R. Delk,  Donald R.
Hollis,  Susan B.  Major and  Bernard  F.  Sergesketter,  options  to acquire an
aggregate of approximately 27,000 shares of Teltrend common stock will vest upon
the merger.

INDEMNIFICATION AND INSURANCE

         Westell  has  agreed  that,  from and after the  effective  time of the
merger,  Teltrend,  as a wholly-owned  subsidiary of Westell, will indemnify and
hold harmless all of Teltrend's  past and present  officers and directors to the
same  extent  and in the same  manner and  subject  to the same  limits as these
persons were indemnified on the date the merger agreement was signed.

         Further,  for six years  following  the  merger,  Westell has agreed to
cause  Teltrend  to use its  reasonable  best  efforts  to  provide  one or more
policies  of  directors'  and  officers'  liability  insurance  that  provide(s)
coverage for events  occurring  prior to the effective time of the merger.  This
insurance must be  substantially  similar to Teltrend's  existing  policy or, if
substantially  equivalent  insurance  coverage is unavailable,  the most similar
available  coverage;  provided,  however,  that in no  event  will  Teltrend  be
required  to pay an annual  premium for the  insurance  in excess of 150% of the

<PAGE>


last annual premium paid prior to the date the merger  agreement was signed.  If
the insurance  expires,  is terminated or canceled during the six-year period or
exceeds  the  maximum  premium,  Westell  will cause  Teltrend to obtain as much
directors'  and  officers'  liability  insurance  as can  be  obtained  for  the
remainder of the period for an  annualized  premium not in excess of the maximum
premium,  on terms and conditions no less advantageous than Teltrend's  existing
directors' and officers' liability insurance.

         In addition, in the event that

          o    the  indemnification or advancement of expenses to be provided by
               Teltrend following the merger,  together with the insurance to be
               maintained  by Teltrend,  after each is fully  exhausted,  is not
               adequate to fully indemnify or provide advancement of expenses to
               any covered  party to the same extent and in the same manner that
               such  indemnification  or advancement of expenses would have been
               required to be provided by Teltrend  prior to the effective  time
               of the merger, and
          o    there has been a diminution in Teltrend's net book value from its
               net book value as  reflected  on its  October  30,  1999  balance
               sheet,

then  Westell has agreed to  indemnify  the  covered  party to the extent of the
diminution.

DIRECTORS AND EXECUTIVE OFFICERS OF WESTELL FOLLOWING THE MERGER

         Westell has agreed to take such  actions as are  necessary  so that the
Westell Board immediately following the merger includes Howard L. Kirby, Jr. and
Bernard F. Sergesketter, each of whom is currently a director of Teltrend. It is
expected that all of the directors  currently  serving on the Westell Board will
continue  to serve as members of the Westell  Board  immediately  following  the
merger. In January 2000,  Westell's Board increased its size from six members to
eight and elected Marc Zionts, Westell's chief executive officer, and J. William
Nelson,   Westell's   president,   as  directors  to  fill  the  newly   created
directorships.  In addition, in January 2000, Ormand Wade resigned as a director
and was replaced, by the vote of the remaining directors, by Thomas A. Reynolds,
III. Mr. Reynolds is a partner with Winston & Strawn,  an international law firm
headquartered  in Chicago which he joined in 1983. Mr. Reynolds is also a member
of the board of directors of Smurfit Stone Container Corporation,  an integrated
producer of paperboard and paper-based packaging products.

         Mr. Kirby has served as the president,  the chief executive officer and
a director of Teltrend  since January 1990.  Mr. Kirby was named chairman of the
Teltrend   Board  in  February   1997.   Mr.  Kirby  began  his  career  in  the
telecommunications   industry  in  1962  with  Collins  Radio   Company   (which
subsequently  became a part of  Rockwell  International  Corporation),  where he
spent 20 years in various  management  positions in  engineering,  marketing and
sales.  From 1982 to 1984,  Mr.  Kirby was the director of planning and business
development for U.S.  Telephone,  now part of Sprint  Corporation.  In 1984, Mr.
Kirby became the vice  president  and general  manager at Pulse  Communications,
Inc., a subsidiary  of Hubbell  Incorporated,  and held that  position  until he
joined Teltrend in 1990. Mr. Kirby is 63 years old.

         Mr.  Sergesketter  has been a director of Teltrend  since January 1996.
Since August 1994, Mr.  Sergesketter  has been the president and chief executive
officer of  Sergesketter  & Associates  Inc., a firm which  provides  consulting
services in the areas of marketing,  telecommunications  and quality management.
Prior to that, Mr. Sergesketter held various positions  (including  positions in
engineering,  finance, sales and marketing) during his 36-year career with AT&T,
including,  from January 1983 to August 1994,  vice president -- central region.
As vice  president  --  central  region of AT&T,  Mr.  Sergesketter's  principal
responsibilities  were for AT&T's sales and marketing operations in the midwest.
Mr.  Sergesketter  is a director of the Illinois  Institute of  Technology,  The
Cradle, The Sigma Chi Foundation,  and Mather Foundation. Mr. Sergesketter is 63
years old.

         Upon  consummation  of the  merger,  Teltrend  will  be a  wholly-owned
subsidiary  of Westell.  The current  directors  of Teltrend  will resign at the
effective time, and Westell will name a new board of directors for Teltrend.

         Westell has not yet determined  whether the current executive  officers
of Teltrend will continue to serve in executive positions at Westell or in their
current  positions  with  Teltrend,  which will become a subsidiary  of Westell,
after the effective  time of the merger.  Such decisions are expected to be made
promptly following the effective time.

                                  CHAPTER THREE
                             THE MEETINGS AND VOTING

                           THE WESTELL SPECIAL MEETING

PURPOSE OF THE MEETING

         At the Westell special meeting,  Westell  stockholders will be asked to
consider and vote upon the  proposals  described  below.  Each  proposal will be
voted upon separately by Westell  stockholders;  however, the merger will not be
completed  and the  actions  contemplated  in the merger  proposals  will not be
effected  unless each of the  proposals  are  approved by the  required  vote of
Westell stockholders.

         (1) Westell  stockholders  are being  asked to approve the  issuance of
shares of Westell Class A Common Stock in accordance with the merger agreement.

         (2)  Westell  stockholders  are  being  asked to  approve  and adopt an
amendment to Westell's  Amended and Restated  Certificate  of  Incorporation  to
increase the number of shares of Class A Common Stock that Westell is authorized
to issue to 85 million from 65.5 million.

         Westell does not  currently  have enough  authorized  shares of Westell
Class A Common  Stock to  consummate  the  merger.  As a  result,  and given the
reservation  of the shares to be issued upon  conversion  of  Westell's  Class B
Common Stock and  convertible  debentures  and upon the exercise of  outstanding
options  and  warrants,  the  authorized  shares must be  increased  to at least
approximately  71 million  shares in order to effect the  merger.  In  addition,
since  the  number  of  shares  of Class A Common  Stock  into  which  Westell's
convertible  debentures and warrants is variable,  and therefore may increase in
certain  circumstances,  Westell  must have the  ability to  reserve  additional
shares for issuance  with  respect  thereto.  The Westell  Board  believes  that
increasing the authorized  shares to 85 million is advisable since it will allow
Westell to reserve  such  additional  shares,  if  necessary,  and will  provide
Westell with some additional flexibility to issue shares of Class A Common Stock
in  connection  with  employee   benefit  plans,   possible   future   financing
transactions,  acquisitions  of other  companies or business  properties,  stock
splits, and other corporate purposes. While the issuance of additional shares of
Class A Common Stock may dilute the ownership  interests of a person  seeking to
obtain control of Westell, and thus discourage a change in control of Westell by
making it more  difficult or costly,  Westell is not aware of anyone  seeking to
accumulate Class A Common Stock for such purpose and has no present intention of
using any additional  Class A Common Stock to deter a change in control.  Except
as otherwise required by applicable law or the rules of the National Association
of Securities  Dealers,  Inc.,  authorized but unissued shares of Class A Common
Stock may be issued at such time, for such purposes,  and for such consideration
as  the  Westell  Board  may  determine  to  be  appropriate,   without  further
authorization by the Westell stockholders.

         It is not expected that any matters other than the proposals  described
above will be brought before the Westell special  meeting.  If,  however,  other
matters  are  properly  presented,  the  persons  named in the  proxy  will have
authority to vote in accordance with their judgment on any such matters,  except
that no proxy that  directs a vote  against or  abstention  with  respect to the
merger  proposals  will be voted to  adjourn or  postpone  the  Westell  special
meeting.

DATE, PLACE AND TIME

         The Westell special meeting will be held at 10:00 a.m.,  local time, on
_________________,  2000, at Westell's corporate headquarters, 750 North Commons
Drive, Aurora, Illinois 60504.

RECORD DATE; STOCK OUTSTANDING

         The Westell Board has fixed the close of business on  __________,  2000
as the record date for  determining the holders of Westell common stock that are
entitled to receive notice of and to vote at the Westell special meeting. On the
record date,  there were _____  shares of Westell  Class A Common Stock and ____

<PAGE>


shares of Westell Class B Common Stock outstanding.  Each share of Westell Class
A Common Stock entitles its holder to one vote and each share of Westell Class B
Common Stock entitles its holder to four votes.

VOTES REQUIRED FOR APPROVAL

         Each proposal will be voted upon separately by Westell's  stockholders,
with the  holders  of  shares of Class A Common  Stock and Class B Common  Stock
voting together as a single class with respect to each proposal. The affirmative
vote of a majority of the total  votes cast is required to approve the  issuance
of shares of Westell's  Class A Common  Stock in the merger and the  affirmative
vote of a majority  of the total  votes  outstanding  as of the  record  date is
required to approve the amendment to Westell's Amended and Restated  Certificate
of Incorporation.

         Because the amendment to Westell's Amended and Restated  Certificate of
Incorporation   requires   the  approval  of  a  majority  of  the  total  votes
outstanding,  abstentions or the failure to vote and broker  non-votes will have
the same  effect as a negative  vote.  A broker  non-vote  occurs when a nominee
holding  shares for a beneficial  owner does not vote on a proposal  because the
nominee does not have  discretionary  voting power with respect to that item and
has not received instructions from the beneficial owner.

QUORUM REQUIREMENT

         A quorum of Westell  stockholders is necessary to hold a valid meeting.
The presence in person or by proxy of holders of shares  representing a majority
of Westell's  outstanding votes on the record date is a quorum.  Abstentions and
broker  non-votes  count as present for  establishing  a quorum.  Shares held by
Westell in its  treasury  are not  counted as  outstanding  for quorum or voting
purposes.

STOCK OWNERSHIP OF MANAGEMENT; VOTING AGREEMENT

         On _____,  2000,  directors and executive officers of Westell and their
affiliates  owned and were entitled to vote ___ shares of Westell Class A Common
Stock and all outstanding  shares of Class B Common Stock, or approximately  __%
of Westell's outstanding votes.

         Messrs.  Penny  and  Simon,  two of  Westell's  directors,  who are the
co-trustees of the Westell Technologies, Inc. Voting Trust, and beneficially own
approximately  80% of the voting power of Westell,  have agreed to vote in favor
of the merger proposals if a majority of Westell's public  stockholders so vote.
For purposes of the voting agreement,  Westell's public stockholders include all
holders of Westell Class A Common Stock, other than Messrs.  Penny and Simon and
members of their families and any officers or directors of Westell.

         While the  co-trustees  are  obligated  to vote in favor of the  merger
proposals if a majority of Westell's  public  stockholders  so vote,  the voting
agreement does not prevent or prohibit the co-trustees from also voting in favor
of the proposals even if a majority of Westell's public  stockholders reject the
proposals. The co-trustees have indicated their current intention to vote as the
majority of Westell's  non-affiliated,  public stockholders vote with respect to
the  proposals.  The voting  agreement  is  described  in more detail in "Voting
Agreement with Westell Controlling Stockholders" on page II-18.

VOTING AND REVOCATION OF PROXIES

         Westell Class A Common Stock represented by a proxy properly signed and
received  at or  prior  to the  Westell  special  meeting,  unless  subsequently
revoked,  will be voted in accordance with the instructions  thereon. IF A PROXY
IS SIGNED  AND  RETURNED  WITHOUT  INDICATING  ANY VOTING  INSTRUCTIONS,  SHARES
REPRESENTED BY THE PROXY WILL BE VOTED "FOR" EACH OF THE PROPOSALS.  If you vote
in favor of either of the proposals, the proxy holders may, in their discretion,
vote your shares to adjourn the Westell  special  meeting to solicit  additional
proxies in favor of the proposals.

         A Westell  stockholder  who  executes  a proxy  may  revoke it any time
before it is exercised by giving  written  notice of revocation to the corporate
secretary of Westell,  by subsequently  filing another,  later-dated proxy or by

<PAGE>


attending the Westell  special  meeting and voting in person.  Attendance at the
Westell  special  meeting will not in and of itself  constitute  revocation of a
proxy.

SOLICITATION OF PROXIES

         The  Westell  Board is  soliciting  proxies  on behalf of  Westell.  In
addition to solicitation by mail, directors,  officers and employees of Westell,
none of whom will be  specifically  compensated  for such services,  may solicit
proxies from the  stockholders  of Westell,  personally or by telephone or other
forms of  communication.  Brokerage  houses,  nominees,  fiduciaries  and  other
custodians  will be requested  to forward  soliciting  materials  to  beneficial
owners and will be reimbursed for their reasonable  expenses incurred in sending
proxy materials to beneficial owners.

                          THE TELTREND SPECIAL MEETING

GENERAL

         This joint proxy  statement/prospectus  is  furnished to the holders of
Teltrend  common stock in  connection  with the  solicitation  of proxies by the
Teltrend  Board  for use at the  Teltrend  special  meeting  to be held  for the
purposes described in this document.

         This joint proxy  statement/prospectus  is also  furnished  to Teltrend
stockholders  as a  prospectus  in  connection  with the  issuance by Westell of
shares of Westell Class A Common Stock pursuant to the merger.

PURPOSE OF THE MEETING

         At the Teltrend special meeting, Teltrend stockholders will be asked to
consider  and vote upon a  proposal  to adopt the merger  agreement.  The merger
agreement is attached as Appendix A to this joint proxy statement/prospectus and
described under "The Merger Agreement" beginning on page IV-1.

         It is not expected that any matters  other than the proposal  described
above will be brought before the Teltrend  special meeting.  If, however,  other
matters  are  properly  presented,  the  persons  named in the  proxy  will have
authority to vote in accordance with their judgment on any such matters,  except
that no proxy that  directs a vote  against or  abstention  with  respect to the
adoption  of the  merger  agreement  will be voted to adjourn  or  postpone  the
Teltrend special meeting.

DATE, PLACE AND TIME

         The Teltrend special meeting will be held at 10:00 a.m., local time, on
________,  __________,  2000, at Teltrend's corporate headquarters,  620 Stetson
Avenue, St. Charles, Illinois 60174.

RECORD DATE; STOCK OUTSTANDING

         The Teltrend Board has fixed the close of business on __________,  2000
as the record date for determining the holders of Teltrend common stock that are
entitled to receive notice of and to vote at the Teltrend  special  meeting.  On
the record date,  there were _____ shares of Teltrend common stock  outstanding.
Each share of Teltrend common stock entitles its holder to one vote.

VOTES REQUIRED FOR APPROVAL

         The affirmative vote of a majority of the total votes outstanding as of
the record date is required to approve the adoption of the merger agreement.

         Because the adoption of the merger agreement requires the approval of a
majority of the total votes outstanding,  abstentions or the failure to vote and
broker non-votes will have the same effect as a negative vote. A broker non-vote
occurs when a nominee  holding shares for a beneficial  owner does not vote on a

<PAGE>


proposal  because  the nominee  does not have  discretionary  voting  power with
respect  to that  item and has not  received  instructions  from the  beneficial
owner.

QUORUM REQUIREMENT

         A quorum of Teltrend stockholders is necessary to hold a valid meeting.
The presence in person or by proxy of holders of shares  representing a majority
of the  Teltrend's  outstanding  common  stock on the  record  date is a quorum.
Abstentions  and broker  non-votes  count as present for  establishing a quorum.
Shares held by  Teltrend in its  treasury  are not  counted as  outstanding  for
quorum or voting purposes.

STOCK OWNERSHIP OF MANAGEMENT

         On _____, 2000,  directors and executive officers of Teltrend and their
affiliates  owned and were entitled to vote ___ shares of Teltrend common stock,
or approximately  ___% of the outstanding shares of Teltrend common stock. These
individuals and their  affiliates have indicated that they will vote in favor of
approval and adoption of the merger agreement.

VOTING AND REVOCATION OF PROXIES

         Teltrend  common  stock  represented  by a proxy  properly  signed  and
received  at or prior  to the  Teltrend  special  meeting,  unless  subsequently
revoked,  will be voted in accordance with the instructions  thereon. IF A PROXY
IS SIGNED  AND  RETURNED  WITHOUT  INDICATING  ANY VOTING  INSTRUCTIONS,  SHARES
REPRESENTED  BY THE  PROXY  WILL BE  VOTED  "FOR"  THE  ADOPTION  OF THE  MERGER
AGREEMENT.  If you vote in favor of adoption of the merger agreement,  the proxy
holders  may, in their  discretion,  vote your  shares to adjourn  the  Teltrend
special meeting to solicit additional proxies in favor of adoption of the merger
agreement.

         A  Teltrend  stockholder  who  executes  a proxy may revoke it any time
before it is exercised by giving  written  notice of revocation to the corporate
secretary of Teltrend,  by subsequently filing another,  later-dated proxy or by
attending the Teltrend  special meeting and voting in person.  Attendance at the
Teltrend  special meeting will not in and of itself  constitute  revocation of a
proxy.

SOLICITATION OF PROXIES

         The Teltrend  Board is  soliciting  proxies on behalf of  Teltrend.  In
addition to solicitation by mail, directors, officers and employees of Teltrend,
none of whom will be  specifically  compensated  for such services,  may solicit
proxies from the  stockholders of Teltrend,  personally or by telephone or other
forms of  communication.  Brokerage  houses,  nominees,  fiduciaries  and  other
custodians  will be requested  to forward  soliciting  materials  to  beneficial
owners and will be reimbursed for their reasonable  expenses incurred in sending
proxy materials to beneficial owners.

                                  CHAPTER FOUR
                              THE MERGER AGREEMENT

         THE  FOLLOWING  IS A  SUMMARY  OF  CERTAIN  PROVISIONS  OF  THE  MERGER
AGREEMENT,  A COPY OF  WHICH IS  ATTACHED  AS  APPENDIX  A TO THIS  JOINT  PROXY
STATEMENT/PROSPECTUS AND WHICH IS INCORPORATED HEREIN BY REFERENCE. THIS SUMMARY
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE MERGER  AGREEMENT.  ALL WESTELL
STOCKHOLDERS  AND TELTREND  STOCKHOLDERS  ARE URGED TO READ THE MERGER AGREEMENT
CAREFULLY FOR A COMPLETE DESCRIPTION OF THE MERGER.

TERMS OF THE MERGER

         After the  conditions  precedent  to the merger have been  fulfilled or
waived,  a  certificate  of merger will be filed with the Delaware  Secretary of
State.  The merger will become  effective upon the filing of the  certificate of
merger, and Teltrend will become a wholly-owned subsidiary of Westell.

         At the effective time of the merger:

          o    each share of Teltrend common stock outstanding will be converted
               into the right to receive  3.3  shares of Westell  Class A Common
               Stock,  subject  to the  provisions  below  regarding  fractional
               shares;
          o    each option or warrant exercisable for Teltrend common stock will
               be converted  into an option or warrant  exercisable  for Westell
               Class A Common  Stock,  for a number of shares and at an exercise
               price adjusted to reflect the exchange ratio; and
          o    all shares of Teltrend  common  stock,  when  converted,  will no
               longer be outstanding and will automatically be canceled.

         No fractional  shares of Westell Class A Common Stock will be issued in
the merger.  Instead,  each Teltrend stockholder who would otherwise be entitled
to  receive  a  fraction  of a share  of  Westell  Class A Common  Stock,  after
aggregating  all  shares of  Westell  Class A Common  Stock  which the holder is
entitled to receive,  will be paid an amount in cash,  determined by multiplying
the fraction by the average  closing  price per share of Westell  Class A Common
Stock on the Nasdaq  National  Market  during the 10  trading  days  immediately
preceding the effective time.

         Because the  exchange  ratio is fixed,  the number of shares of Westell
Class A Common Stock to be received by Teltrend  stockholders  upon consummation
of the merger will depend only on the number of shares of Teltrend  common stock
outstanding  at the effective  time and will not be adjusted due to any increase
or  decrease in the market  price of the  Teltrend  common  stock or the Westell
Class A Common Stock. This includes any such increase or decrease after the date
of this  joint  proxy  statement/prospectus  and after the dates of the  Westell
special meeting and the Teltrend special meeting.

EXCHANGE OF SHARES

         Westell  will  appoint  an  exchange  agent to handle the  exchange  of
Teltrend  stock  certificates  in the merger for  Westell  Class A Common  Stock
certificates  and the  payment of cash in lieu of  fractional  shares of Westell
Class A Common Stock.

         Soon after the effective time, the exchange agent will mail a letter of
transmittal  which will contain  instructions  for delivery of Teltrend stock in
exchange  for  Westell  Class A Common  Stock  (and  cash in lieu of  fractional
shares) to each Teltrend stockholder.  Upon delivery of Teltrend common stock to
the  exchange  agent  and  the  signed  letter  of  transmittal,   the  Teltrend
stockholder will receive certificates representing the number of whole shares of
Westell Class A Common Stock to which the holder of the  certificate is entitled
under the merger agreement,  and cash in lieu of any fractional  shares, and the
Teltrend certificates surrendered will be canceled. TELTREND STOCKHOLDERS SHOULD
NOT SURRENDER THEIR  CERTIFICATES  FOR EXCHANGE UNTIL THEY RECEIVE THE LETTER OF
TRANSMITTAL FROM THE EXCHANGE AGENT.



<PAGE>


TREATMENT OF TELTREND STOCK OPTIONS

         Westell and Teltrend have each agreed to take all actions  necessary to
cause each option to purchase shares of Teltrend common stock which is unexpired
and  unexercised as of the effective time to be  automatically  converted at the
effective  time into an option  (1) to  purchase  a number of shares of  Westell
Class A Common  Stock  equal to the number of shares of  Teltrend  common  stock
subject to such option  multiplied by the exchange ratio of 3.3, which is (2) at
an exercise  price per share equal to the  exercise  price in effect  under such
option  immediately  prior to the effective time divided by the exchange  ratio.
The date of  grant  of each  converted  option  will be the  date on  which  the
corresponding  Teltrend  option was granted.  Each option,  as  converted,  will
otherwise  be  subject  to the same terms and  conditions  as the  corresponding
Teltrend option, except that:

          o    if the applicable  Teltrend option  provides for  acceleration of
               vesting upon the merger,  the converted  option will be so vested
               following the merger; and
          o    the terms of Teltrend options  outstanding  under Teltrend's 1997
               Non-Employee  Director  Stock Option Plan will be amended so that
               the options may be exercised for longer  periods than  previously
               provided, as follows:
               o    with respect to those  Teltrend  directors who do not become
                    directors of Westell following the merger,  until six months
                    following  the  effective  time,  or the date on  which  the
                    options expire (whichever is earlier), and
               o    with respect to Howard L. Kirby and Bernard F. Sergesketter,
                    Teltrend  directors  who will  become  directors  of Westell
                    following  the merger,  until 90 days  following the date on
                    which such person ceases to be a director of Westell, or the
                    date on which the options expire (whichever is earlier).

      Westell will file with the SEC a  registration  statement on Form S-8 with
respect to the issuance of shares of Westell  Class A Common Stock upon exercise
of the converted options.

that it and each of its subsidiaries will:

          o    not incur any  indebtedness,  subject to certain  ordinary course
               exceptions;
          o    not take or fail to take any action which would cause  Westell or
               Teltrend's  stockholders  to  recognize  gain or loss for federal
               income  tax  purposes  as a  result  of the  consummation  of the
               merger,  except to the extent that any stockholders  receive cash
               in lieu of fractional shares;
          o    not make any  acquisition of any assets or businesses  other than
               in the ordinary course of business;
          o    not sell,  pledge,  dispose of or encumber any material assets or
               businesses other than sales in the ordinary course of business;
          o    except as otherwise  permitted  pursuant to the merger agreement,
               not take any action which would be  reasonably  likely to prevent
               Westell from (1) obtaining any necessary governmental  approvals,
               (2)  performing  its  covenants and  agreements  under the merger
               agreement,  or (3) consummating the transactions  contemplated by
               the merger agreement;
          o    use all  reasonable  efforts  to  preserve  intact  its  business
               organization  and  goodwill,  keep  available the services of its
               present officers and key employees, and preserve the goodwill and
               business  relationships with customers and others having business
               relationships  with it and not engage in any action,  directly or
               indirectly,  with the intent to adversely impact the transactions
               contemplated by the merger agreement;
          o    not implement any change in accounting  principles,  practices or
               methods, other than as may be required by United States generally
               accepted   accounting   principles,   the  financial   accounting
               standards  board,  the SEC or any other  government  authority or
               oversight agency; and
          o    use commercially  reasonable efforts to maintain with financially
               responsible  insurance companies insurance on its tangible assets
               and its  businesses  in such  amounts and against  such risks and
               losses as are consistent with past practice.

         No Solicitation by Teltrend

         Teltrend has agreed that it and its  subsidiaries  and their  officers,
directors,  employees  and  advisors  will  not  initiate,  solicit,  negotiate,
knowingly  encourage  or  provide  non-public  or  confidential  information  to
facilitate any proposal or offer to acquire all or any  substantial  part of the
business and properties of Teltrend or any capital stock of Teltrend.

         However,  notwithstanding the restrictions in the preceding  paragraph,
Teltrend may, in response to an  unsolicited  written  proposal or indication of
interest with respect to a potential or proposed acquisition transaction,

          o    furnish  confidential or non-public  information to a financially
               capable  potential  acquirer,  subject to a  confidentiality  and
               standstill  agreement  no more  favorable  than  the one  between
               Teltrend and Westell; and

<PAGE>

          o    negotiate with such potential acquirer,

but  only if the  Teltrend  Board in good  faith,  after  consultation  with its
outside legal counsel,  determines that the failure to provide such confidential
or non-public  information to or negotiate  with such  potential  acquirer would
constitute a breach of its fiduciary duty to the Teltrend stockholders.

         Teltrend must notify Westell as soon as practicable  after (1) Teltrend
has  received any  acquisition  proposal,  (2) the  Teltrend  Board or its chief
executive  officer or chief financial  officer has actual  knowledge that anyone
intends to make an acquisition  proposal, or (3) Teltrend has received specified
requests  for  nonpublic  information  relating to it or its  subsidiaries.  The
notice must be made orally and in writing and must indicate in reasonable detail
the  identity  of the  offeror  and the terms and  conditions  of the  proposal,
inquiry or contact.  Teltrend must keep Westell fully informed of the status and
details of any such acquisition proposal or request.

         Teltrend Board's Covenant to Recommend

         Teltrend  has  agreed  that it will  submit the  merger  agreement  for
adoption  at a meeting of its  stockholders  as  promptly  as  practicable  and,
subject to the next  sentence,  will use its  reasonable  best efforts to obtain
stockholder  adoption of the merger  agreement.  Further,  Teltrend's  Board has
agreed  to  recommend   adoption  of  the  merger   agreement  to  the  Teltrend
stockholders, except as may be required in response to any unsolicited bona fide
written acquisition proposal, in order to comply with its fiduciary duties under
Delaware  corporate law as it determines in good faith,  after consultation with
Teltrend's outside legal counsel.

         Westell Board's Covenant to Recommend

         Westell  has agreed that it will  submit the issues  described  in this
joint proxy  statement/prospectus  for approval at a meeting of its stockholders
as promptly  as  practicable  and,  subject to the next  sentence,  will use its
reasonable best efforts to obtain  stockholder  approval thereof.  Further,  the
Westell Board has agreed to recommend approval of such issues,  except as may be
required,  in response to any bona fide  acquisition  proposal  with  respect to
Westell,  in order to comply with the Westell  Board's  fiduciary  duties  under
Delaware  corporate law as it determines in good faith,  after consultation with
Westell's outside legal counsel.

         Westell has also agreed to authorize and cause an officer of Westell to
vote Westell's shares of capital stock of Theta  Acquisition  Corp. for adoption
of  the  merger  agreement  and to  take  all  additional  actions  as the  sole
stockholder of Theta Acquisition Corp. necessary to adopt the merger agreement.

         Listing of Westell Class A Common Stock

         Westell  has  agreed  to cause the  shares of its Class A Common  Stock
which will be issued in  connection  with the merger and  reserved  for issuance
upon the exercise of the  converted  Teltrend  stock options to be listed on the
Nasdaq National Market.

         Covenant to Cooperate

         Westell and Teltrend have each agreed to use all reasonable  efforts to
do  everything  necessary or advisable  to  consummate  the merger and the other
transactions  contemplated by the merger  agreement.  In addition,  Teltrend has
granted to Westell  the right,  at  Westell's  expense,  to  participate  in any
litigation commenced against Teltrend relating to the transactions  contemplated
by the merger  agreement.  Teltrend  has also agreed that it will not settle any
such  litigation  without  Westell's  prior  consent,  unless the Teltrend Board
determines  in good faith  after  consultation  with  Teltrend's  outside  legal
counsel  that  the  existence  or  exercise  of such  right  with  respect  to a
particular settlement would violate the fiduciary duties of the Teltrend Board.

         Director's and Officer's Indemnification

         Westell  has  agreed  that  from and after  the  effective  time of the
merger,  Teltrend,  as a wholly-owned  subsidiary of Westell, will indemnify and
hold harmless all of Teltrend's  past and present  officers and directors to the

<PAGE>


same  extent  and in the same  manner  and  subject  to the same  limits as such
persons were  indemnified  on December 13, 1999  pursuant to Delaware  corporate
law,  Teltrend's  certificate of incorporation or Teltrend's  bylaws for acts or
omissions occurring at or prior to the effective time of the merger.

         Further,  for six years  following  the  merger,  Westell has agreed to
cause  Teltrend  to use its  reasonable  best  efforts  to  provide  one or more
policies  of  directors'  and  officers'  liability  insurance  that  provide(s)
coverage for events  occurring  prior to the effective time of the merger.  This
insurance must be  substantially  similar to Teltrend's  existing  policy or, if
substantially  equivalent  insurance  coverage is unavailable,  the most similar
available  coverage;  provided,  however,  that in no  event  will  Teltrend  be
required  to pay an annual  premium for the  insurance  in excess of 150% of the
last annual  premium  paid prior to the  December  13,  1999.  If the  insurance
expires,  is  terminated or canceled  during the six-year  period or exceeds the
maximum  premium,  Westell will cause Teltrend to obtain as much  directors' and
officers' liability insurance as can be obtained for the remainder of the period
for an  annualized  premium not in excess of the maximum  premium,  on terms and
conditions  no  less  advantageous  than  Teltrend's   existing  directors'  and
officers' liability insurance.

         In addition, in the event that

          o    the  indemnification or advancement of expenses to be provided by
               the Teltrend following the merger, together with the insurance to
               be maintained by Teltrend,  after each is fully exhausted, is not
               adequate to fully indemnify or provide advancement of expenses to
               any covered  party to the same extent and in the same manner that
               such  indemnification  or advancement of expenses would have been
               required to be provided by Teltrend  prior to the effective  time
               of the merger, and
          o    there has been a diminution in Teltrend's net book value from its
              net book value as reflected on its October 30, 1999 balance sheet,

then  Westell has agreed to  indemnify  the  covered  party to the extent of the
diminution.

         Teltrend Severance Policy

         Westell has agreed that, at the effective  time of the merger,  it will
assume,  and, subject to its right to thereafter amend,  modify or terminate the
policy in accordance with its terms,  Westell will  thereafter pay,  perform and
discharge when due, all of Teltrend's  obligations  under  Teltrend's  Executive
Officer  Severance Plan with respect to the individuals who  participated in the
policy as of December 13, 1999, the date the merger agreement was signed.

         Other Covenants

         The  merger  agreement  contains  various  other  covenants,  the  most
significant of which are as follows:

          o    Westell  and  Teltrend  have each  agreed to  provide  reasonable
               access to the other to its properties and records;
          o    Westell  and  Teltrend  have each agreed to prepare and file this
               joint  proxy  statement/prospectus  and  to  use  all  reasonable
               efforts to have the registration  statement,  of which this joint
               proxy  statement/prospectus  is a part, declared effective by the
               SEC;
          o    Westell and Teltrend  have each agreed to consult with each other
               before  issuing  any press  release  or  similar  written  public
               statement with respect to the merger agreement or the merger; and
          o    Westell and  Teltrend  have each  agreed to promptly  notify each
               other of specified events.

         Teltrend will have the right to terminate the merger agreement:

          o    if the merger is not  completed by June 30, 2000 (unless due to a
               delay or default  on the part of  Teltrend),  provided,  however,
               that such date shall be extended to September  30, 2000 if, as of
               June 30,  2000,  the parties  are engaged in ongoing  discussions

               contemplated by the merger agreement;
          o    if the merger is  enjoined by a final,  unappealable  court order
               not entered at the request or with the support of Teltrend and if

               of such order;
          o    if:
               o    Teltrend  receives an offer or proposal  from any  potential

                    with  respect  to a merger,  sale of  substantial  assets or
                    other business combination involving Teltrend;
               o    the Teltrend Board determines, in good faith and after
                    consultation  with an independent  financial  advisor,  that
                    such  offer or  proposal,  if  consummated  pursuant  to its
                    terms,  would  result in an  transaction  more  favorable to
                    Teltrend's  stockholders  than the  merger and  resolves  to
                    accept this superior proposal;
               o    Teltrend  shall have given  Westell two days' prior  written
                    notice  of its  intention  to  terminate  pursuant  to  this
                    provision; and
               o    such termination  shall not be effective until Teltrend pays
                    to Westell the $7.2 million break-up fee described below;
          o    if the Westell  stockholders  fail to approve the issuance of the

               Westell's Amended and Restated Certificate of Incorporation, each
               as contemplated by this joint proxy statement/prospectus;
          o    if the Teltrend  stockholders  fail to adopt the merger agreement
               at a duly held meeting called for such purpose or any adjournment
               thereof;
          o    if Westell's  representations  and warranties fail to be true and
               correct in all material  respects in  accordance  with the merger
               agreement;
          o    if Westell  fails to perform in any  material  respect any of its
               material covenants in the merger agreement and does not cure such
               default in all material  respects  within 30 days after notice of
               such default is given by Teltrend; or
          o    if the Board of  Directors  of  Westell  shall have  resolved  to
               accept a superior proposal.

         Westell will have the right to terminate the merger agreement:

          o    if Teltrend's  representations and warranties fail to be true and
               correct in all material  respects in  accordance  with the merger
               agreement;

               Corp.),  provided,  however,  that such date shall be extended to

               proposal or shall have  recommended to the Teltrend  stockholders

                    consummating the transactions  contemplated  thereby,
               o    as a  result,  the  Westell  Board  does  not  recommend  to

                    Incorporation, and
               o    the  Westell  Board  determines,  in good  faith  and  after
                    consultation  with an independent  financial  advisor,  that
                    such  offer or  proposal,  if  consummated  pursuant  to its
                    terms,  would  result in a  transaction  more  favorable  to
                    Westell's  stockholders  than the  merger  and  resolves  to
                    accept such superior proposal.

         Termination Fees

         Teltrend has agreed to pay to Westell a break-up  fee of  approximately
$7.2 million under the following circumstances:

          o    Teltrend  terminates  the  merger  agreement  as  a  result  of a
               superior  proposal,  in  accordance  with the  termination  right
               described above;
          o    Westell  terminates  the merger  agreement  because the  Teltrend
               Board  has  resolved  to  accept  a  superior   proposal  or  has
               recommended to the Teltrend  stockholders  that they tender their
               shares in a tender offer commenced by a third party; or
          o    either  Westell  or  Teltrend  terminates  the  merger  agreement
               because  the  Teltrend  stockholders  have not adopted the merger
               agreement  at a duly held  meeting,  but only if Teltrend  enters
               into  a  definitive  agreement  with  respect  to an  acquisition
               transaction within three months following such termination.

         Westell has agreed to pay to Teltrend a break-up  fee of  approximately
$7.2 million under the  following  circumstances:

          o    either  Westell  or  Teltrend  terminates  the  merger  agreement
               because the Westell Board resolves to accept a superior proposal,
               which requires the merger agreement to be terminated, but only if
               Westell  enters into a  definitive  agreement  with respect to an
               acquisition   transaction   within  nine  months  following  such
               termination; or
          o    Westell,  in  accordance  with  the  merger  agreement,  does not
               recommend  to its  stockholders  approval of the  issuance of the
               Westell  Class A Common  Stock in the merger or the  amendment to
               Westell's Amended and Restated Certificate of Incorporation, each
               as  described  in  this  joint  proxy  statement/prospectus,  and
               Teltrend  terminates  the merger  agreement  because  the Westell
               stockholders  have failed to approve these matters at a duly held
               meeting called for that purpose,  but only if Westell enters into
               a definitive agreement with respect to an acquisition transaction
               within three months following such termination.

OTHER EXPENSES

         Except  as  described  above,  all  costs  and  expenses   incurred  in
connection with the merger agreement and the transactions  contemplated  thereby
will be paid by the party  incurring  such  expenses,  except that all  expenses
incurred  in   connection   with  printing  and  filing  the  this  joint  proxy
statement/prospectus will be shared equally by Teltrend and Westell.

taken  by the  parties'  respective  Boards  of  Directors  or  duly  authorized
committees thereof and then only by an instrument in writing signed on behalf of
each of the parties and in compliance with applicable law. An amendment may take
place at any time prior to the closing date, whether before or after approval by

                            CERTAIN LEGAL INFORMATION

       MATERIAL DIFFERENCES IN RIGHTS OF TELTREND AND WESTELL STOCKHOLDERS

         The  following  summary  compares  certain  rights  of the  holders  of
Teltrend  common  stock to the rights of the  holders of Westell  Class A Common
Stock.  The rights of holders of Teltrend common stock are principally  governed
by Delaware law, the Teltrend  Restated  Certificate  of  Incorporation  and the
Teltrend bylaws.  Upon completion of the merger, the Teltrend  stockholders will
become  holders  of  Westell  Class A Common  Stock,  and their  rights  will be
principally   governed  by  Delaware  law,  the  Westell  Amended  and  Restated
Certificate of  Incorporation  and the Westell bylaws.  The rights of holders of
Westell  Class A Common Stock are  different in certain  material  respects from
those of holders of Teltrend common stock.

         The  statements  set forth this  section  with  respect to the Delaware
General   Corporation  Law,  Westell's  Amended  and  Restated   Certificate  of
Incorporation and bylaws, and Teltrend's  Restated  Certificate of Incorporation
and bylaws are brief  summaries.  For more  information as to how you can obtain

AUTHORIZED CAPITAL STOCK

         Westell's  authorized  capital stock currently consists of 65.5 million
shares of Class A Common Stock, 25 million shares of Class B Common Stock, and 1
million shares of preferred stock, each with a par value of $0.01 per share. If,
at the Westell special meeting,  the Westell  stockholders approve the amendment
to Westell's Amended and Restated  Certificate of  Incorporation,  the number of
authorized  shares of  Westell  Class A Common  Stock  will be  increased  to 85
million. As of ____, 2000,  __________ shares of Class A Common Stock and shares
of Class B Common  Stock  were  issued and  outstanding.  As of the date of this
joint proxy  statement/prospectus,  no classes or series of preferred  stock had
been  designated  by the  Westell  Board and  therefore  no  shares  of  Westell
preferred stock were issued or outstanding.

         Teltrend's  authorized  capital stock  consists of 15 million shares of
common stock,  1 million  shares of class A common stock,  and 750,000 shares of
preferred  stock,  each with a par value of $.01 per  share.  As of ____,  2000,
__________  shares of Teltrend  common stock were issued and outstanding and ___
shares of Teltrend common stock were held as treasury shares.  As of the date of
this joint proxy statement/prospectus, 80,000 shares of preferred stock had been
designated as Series A Junior  Participating  Preferred Stock in connection with
Teltrend's  stockholder rights plan,  described below, and no shares of Teltrend
class  A  common  stock  or  Teltrend   preferred   stock  or  Series  A  Junior
Participating Preferred Stock were issued or outstanding.

DIVIDENDS

         The holders of Teltrend common stock are entitled to dividends when and
as  they  are  declared,   whether  in  cash,  property  or  securities  of  the
corporation.  In the event  Teltrend  issues shares of its class A common stock,
then the holders of Teltrend common stock and Teltrend class A common stock will
be entitled to dividends at the same rate per share,  provided that if dividends
are  declared  which are  payable  in  shares of common  stock or class A common
stock,  dividends  will be  declared  payable  at the same rate on each class of
common stock and the  dividends  payable to holders of common stock will be paid
in shares of common stock and the dividends payable to holders of class A common
stock  will be paid in shares  of class A common  stock.  In the event  Teltrend
issues shares of its Series A Junior  Participating  Preferred Stock, holders of
that  series will be entitled to receive  quarterly  dividends  when,  as and if
declared by the Teltrend Board out of funds legally available for such purposes.
The holders'  right to any dividend is subject to any prior and superior  rights
of any  holders of Teltrend  stock  ranking  prior and  superior to the Series A
Junior Participating Preferred Stock with respect to dividends.

         Holders  of  record  of  shares  of  Westell  Class A Common  Stock are
entitled  to receive  dividends  when,  if and as may be declared by the Westell
Board out of funds legally  available for such  purposes,  although no dividends
may be declared or paid with respect to Westell's  Class A Common Stock unless a

<PAGE>


dividend,  at the same rate per share, is  simultaneously  declared or paid with
respect to Westell's  Class B Common Stock.  In the case of a stock  dividend or
distribution,  holders of Class A Common  Stock are entitled to receive the same
percentage  dividend or  distribution  as holders of Class B Common Stock except
that stock dividends and distributions shall be made in shares of Class A Common
Stock to the  holders  of Class A Common  Stock and Class B Common  Stock to the
holders of Class B Common Stock.

VOTING RIGHTS

         The holders of Teltrend  common stock are each entitled to one vote per
share held on all matters voted on by the  stockholders.  The holders of Westell
Class A Common  Stock  are each  entitled  to one  vote per  share  held and the
holders of shares of Westell Class B Common Stock are entitled to four votes per
share on all  matters  voted on by the  stockholders.  Holders of shares of both
classes of  Westell's  common  stock will vote as a single  class on all matters
submitted to a vote of stockholders except:

          o    with  respect to future  issuances of Class B Common Stock (which
               must be  approved by the  affirmative  vote of a majority of each
               class of Westell's  common stock,  voting  separately as a class,
               unless  the Class B Common  Stock is being  issued as  payment of
               stock  dividends  on  Class B Common  Stock or in a stock  split,
               reclassification  or other  subdivision  of the  shares of common
               stock); and
          o    as otherwise required by law.

         In the merger,  approximately 19 million shares of Class A Common Stock
will be issued to Teltrend's stockholders, which will represent approximately:

          o    52% of Westell's then outstanding Class A Common Stock;
          o    34% of Westell's then outstanding  Class A Common Stock and Class
               B Common Stock, considered together; and
          o    17% of Westell's then outstanding voting power.

         This  information  is based on the number of shares of Westell  Class A
Common  Stock and Class B Common  Stock and  shares  of  Teltrend  common  stock
outstanding  on ____ __,  2000,  and does not take into account  stock  options,
Westell's warrants or Westell's convertible debentures. Assuming the exercise of
all outstanding options (including the options issued by Westell upon conversion
of the  outstanding  Teltrend  options) and warrants to purchase  Class A Common
Stock and the conversion of Westell's outstanding  convertible debentures at the
current  conversion  price,  upon  completion of the merger,  the Class A Common
Stock to be received by the Teltrend  stockholders will represent  approximately
40% of the  outstanding  Class A Common Stock,  29% of the  outstanding  Class A
Common Stock and Class B Common Stock, considered together, and 16% of Westell's
outstanding voting power.

         Under Delaware law, the  affirmative  vote of the holders of a majority
of the  outstanding  voting  power of any class of common  stock is  required to
approve, among other things, an adverse change in the designations,  preferences
or limitations of the shares of such class of common stock.

CONVERTIBILITY

         Each  share of  Westell  Class B Common  Stock is  convertible,  at the
option of its  holder,  into one share of  Westell  Class A Common  Stock at any
time. In addition, each share of Westell Class B Common Stock will automatically
be converted into one share of Class A Common Stock in the event:

          o    such share is  transferred  to any person or entity  other than a
               "permitted transferee" or
          o    the number of shares of Class B Common Stock  outstanding  at any
               time  represents less than 10% of the total number of outstanding
               shares of Class B Common Stock and Class A Common Stock.


<PAGE>


         A  "permitted  transferee"  includes  (i) any  other  holder of Class B
Common  Stock,  (ii) any member of Robert C.  Penny,  III's  family or Melvin J.
Simon's family,  (iii) Gary F. Seamans,  his spouse or any of their descendants,
and (iv) certain other permitted transferees.

         The Westell Class A Common Stock is not convertible  into Westell Class
B Common Stock.

LIQUIDATION RIGHTS

         As the only class of Teltrend capital stock  outstanding,  the Teltrend
common stock is currently  entitled to all assets  available  for  distributions
after  payment  in  full to  creditors  upon  the  liquidation,  dissolution  or
winding-up of Teltrend. Upon liquidation,  dissolution or winding-up of Westell,
the holders of Westell  Class A Common Stock will share ratably with the holders
of Westell Class B Common Stock in all assets available for distributions  after
payment in full to creditors.

OTHER PROVISIONS

         Neither the holders of Teltrend common stock nor Westell Class A Common
Stock are entitled to  preemptive  or  subscription  rights and neither have any
cumulative voting rights. In any merger,  consolidation or business  combination
at Westell,  the  consideration  to be received  per share by holders of Westell
Class A Common Stock must be  identical  to that  received by holders of Westell
Class B Common  Stock.  In  addition,  no class of Westell  common  stock may be
subdivided,  consolidated,  reclassified  or otherwise  changed unless the other
class of common stock concurrently is subdivided, consolidated,  reclassified or
otherwise changed in the same proportion and in the same manner.

PREFERRED STOCK

         The Westell  Board and the  Teltrend  Board each has the  authority  to
issue shares of preferred stock in one or more series (up to 1 million shares of
preferred  stock may be issued by the Westell Board and up to 750,000  shares of
preferred  stock  may be  issued  by the  Teltrend  Board).  Each  Board has the
authority to fix the rights,  preferences,  privileges and restrictions  thereof
(including  dividend  rights,   conversion  rights,   voting  rights,  terms  of
redemption,  and liquidation  preferences) and the number of shares constituting
any series or the designation of such series, without any further vote or action
by stockholders.

         The issuance of preferred stock by Westell could  adversely  affect the
voting  power of  holders  of both  classes  of  Westell  common  stock  and the
likelihood  that such holders will receive  dividend  payments and payments upon
liquidation  and could have the effect of delaying,  deferring  or  preventing a
change in control of Westell.
Westell has no present plan to issue any shares of preferred stock.

RIGHTS PLAN

         On January 16,  1997,  the  Teltrend  Board  declared a dividend of one
preferred  share purchase right for each  outstanding  share of Teltrend  common
stock.  The dividend was payable on January 27, 1997 to holders of record of the
common stock as of the close of business on that date.  Each right  entitles the
registered  holder  to  purchase  from  Teltrend,  under  certain  circumstances
involving the  acquisition or the  announcement  of the intent to acquire 20% or
more of Teltrend's  common  stock,  one  one-hundredth  of a share of Teltrend's
Series A Junior  Participating  Preferred  Stock at a price of  $160.00  per one
one-hundredth  of a share,  subject to adjustment.  The description and terms of
the rights are detailed in a rights agreement dated January 16, 1997, as amended
on June 1, 1998 and further amended on December 13, 1999, and as the same may be
further  amended from time to time,  between  Teltrend and LaSalle Bank National
Association,  as rights  agent.  The  amendment  dated as of  December  13, 1999
excepted the adoption of the merger agreement and the consummation of the merger
and any related  transactions  from the events which trigger the purchase rights
under the rights agreement.

         Westell does not have a rights plan.

DIRECTORS

Number and Election

         The Teltrend  bylaws  provide  that the number of  directors  who shall
constitute  the whole Board of  Directors  shall not be less than three nor more
than nine, as fixed from time to time by resolution of the Board of Directors by
a majority  vote of the  directors  then in office.  Directors  of Teltrend  are
elected at the annual  meeting of Teltrend  stockholders  and hold office  until
their  respective  successors  are elected and  qualified or until their earlier
resignation  or  removal.   The  Teltrend  Board  currently  consists  of  seven
directors.

         The  Westell  bylaws  provide  that  the  number  of  directors   which
constitute  the whole  board  will be not less  than six nor more than ten.  The
Westell Board currently  consists of eight directors.  Following the merger, the
number of  directors  serving on the Westell  Board will be increased by two and
Messrs.  Kirby and Sergesketter,  currently members of Teltrend's Board, will be
added.

Removal

         Directors of Teltrend  may be removed,  with or without  cause,  by the
stockholders  at any  special  meeting as long as the  notice  for that  meeting
states  that it is for that  purpose.  Similarly,  directors  of Westell  may be
removed, with or without cause, at any meeting of the stockholders by a majority
vote of those stockholder entitled to vote in elections of directors.

SPECIAL MEETINGS

         The Teltrend bylaws provide that a special meeting of the  stockholders
may be called at any time by the  Teltrend  Board,  the chairman of the Teltrend
Board or Teltrend's president and chief executive officer and shall be called be
called by the chairman of the Board,  the president and chief executive  officer
or the secretary at the request in writing of Teltrend  stockholders  holding at
least fifty percent of the shares of stock  outstanding  and entitled to vote at
that meeting.  The Teltrend bylaws provide that special meetings of the Teltrend
Board  may be called by the  chairman  of the  Board,  the  president  and chief
executive officer or by any two of the directors then in office.

         The Westell Amended and Restated Certificate of Incorporation  provides
that special  meetings of the  stockholders may be called by the chairman of the
Westell Board, the president,  a majority of the Westell Board then in office or
stockholders  owning at least a majority of the voting power  represented by all
of the issued and  outstanding  capital  stock of the  corporation.  The Westell
bylaws provide that a special  meeting of the Westell Board may be called by the
chairman of the Board, the president or any two or more directors.

AMENDMENT TO CERTIFICATE OF INCORPORATION AND BYLAWS

Certificate of Incorporation

         Under  the  Delaware  General   Corporation  Law,  the  certificate  of
incorporation  of a  corporation  may be amended by  resolution  of the board of
directors  and  the  affirmative  vote of the  holders  of the  majority  of the
outstanding voting power entitled to vote thereon. With respect to any amendment
to the certificate of incorporation of a corporation that would adversely affect
a particular  class or series of stock,  Delaware law also requires the separate
approval  by the  holders  of the  affected  class or series  of  stock,  voting
together as a single class.

Bylaws

         Under the Delaware General  Corporation Law, the power to adopt, amend,
or repeal bylaws is vested  exclusively  in the  stockholders  entitled to vote,
unless the corporation's  certificate of incorporation confers such power on the
board of directors as well.

         The Teltrend  Restated  Certificate of  Incorporation  and the Teltrend
bylaws  provide for bylaw  amendments by the Teltrend  Board and by the Teltrend
stockholders.

<PAGE>



         The Westell Amended and Restated  Certificate of Incorporation  and the
Westell bylaws provide for bylaw  amendments by either the Westell Board,  or by
the  Westell  stockholders,  provided  that any bylaw  provision  adopted by the
stockholders  may be  amended or  repealed  only by a  majority  of the  Westell
stockholders, voting as a single class.

STOCKHOLDER PROPOSALS

         Each of Teltrend's  and Westell's  bylaws  establish an advance  notice
procedure  for  stockholders  to bring  business  before  an annual  meeting  of
stockholders.

         Teltrend's  bylaws require that any Teltrend  stockholder who wishes to
bring any matter  before an annual  meeting,  including  the  nomination  of any
person for  election as a Teltrend  director,  must  provide  written  notice to
Teltrend at its  principal  executive  offices not less than 60 nor more than 90
days prior to the date of the meeting,  except that if less than 70 days' notice
or prior  public  disclosure  of the  meeting  date is given or made to Teltrend
stockholders,  notice of the matter  must be received no later than the 10th day
following the date of notice or public disclosure of the meeting date, whichever
occurs  first.   Such  notice  must  include  detailed   information  about  the
stockholder  giving the notice and a  description  of the  proposed  business or
nominees for director, as applicable.

         Westell's  bylaws  require that any Westell  stockholder  who wishes to
bring business  before a stockholders  meeting,  including the nomination of any
person for  election  as a Westell  director,  must  provide  written  notice to
Westell no later than 60 days prior to the annual meeting date.

         The notice  requirements in each of Teltrend's and Westell's bylaws are
independent of the notice provisions and deadlines under SEC Rule 14a-8.

BUSINESS COMBINATIONS

         Teltrend  and Westell are both  subject to Section 203 of the  Delaware
General  Corporation  Law, which prohibits a publicly held Delaware  corporation
from engaging in a "business combination" with an "interested stockholder" for a
period  of three  years  after  the time that the  person  became an  interested
stockholder, unless:

          o    prior to such time,  the board of  directors  of the  corporation
               approved either the business combination or the transaction which
               resulted in the stockholder becoming an interested stockholder;
          o    upon  consummation  of  the  transaction  which  resulted  in the
               stockholder  becoming an interested  stockholder,  the interested
               stockholder owned at least 85% of the outstanding voting stock at
               the time the transaction commenced, excluding certain shares held
               by employee directors and employee stock plans; or
          o    at or  subsequent  to such  time,  the  business  combination  is
               approved by the board of directors and authorized at an annual or
               special meeting of the stockholders by the affirmative vote of at
               least 66 2/3% of the  outstanding  voting stock that is not owned
               by the interested stockholder.

         For purposes of Section 203, a "business combination"  includes,  among
other things, a merger, asset sale or other transaction resulting in a financial
benefit  to the  interested  stockholder,  and an  "interested  stockholder"  is
generally a person who, together with affiliates and associates, owns (or within
three years, did own) 15% or more of the corporation's voting stock.

LIMITATION ON LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS

         Limitations  on  Liability  Permitted  by Delaware  Law.  The  Delaware
General   Corporation   Law  provides  that  a   corporation's   certificate  of
incorporation  may include a provision  eliminating  or  limiting  the  personal
liability  of a director to the  corporation  or its  stockholders  for monetary
damages for breach of fiduciary  duty as a director.  However,  no provision can
eliminate or limit the liability of a director for:

          o    any breach of the director's  duty of loyalty to the  corporation
               or its stockholders;
<PAGE>


          o    acts or omissions  not in good faith or that involve  intentional
               misconduct or a knowing violation of the law;
          o    any improper distribution to stockholders;
          o    any  transaction  from which the  director  derived  an  improper
               personal  benefit;  or
          o    any acts or  omissions  prior to the adoption of such a provision
               in the certificate of incorporation.

         Indemnification   Permitted  by  Delaware  Law.  The  Delaware  General
Corporation  Law  generally  permits a corporation  to indemnify its  directors,
officers,  employees and agents against expenses,  judgments,  fines and amounts
paid in  settlement  actually  and  reasonably  incurred  in  connection  with a
third-party  action,  other  than a  derivative  action,  and  against  expenses
actually and  reasonably  incurred in the defense or  settlement of a derivative
action, provided that there is a determination that the individual acted in good
faith and in a manner  reasonably  believed  to be in or not opposed to the best
interests of the corporation.  Such determination  shall be made, in the case of
an individual who is a director or officer at the time of such determination:

          o    by a majority of the  disinterested  directors,  even though less
               than a quorum;
          o    by a committee of such directors designated by a majority vote of
               such directors, even though less than a quorum;
          o    if  there  are no  independent  directors  or if the  independent
               directors so direct,  by  independent  legal counsel in a written
               opinion; or
          o    by the stockholders.

         Without court  approval,  however,  no  indemnification  may be made in
respect of any derivative  action in which such individual is adjudged liable to
the corporation.  The Delaware General Corporation Law requires  indemnification
of directors and officers for expenses  relating to a successful  defense on the
merits or otherwise of a derivative or third-party action.

         Westell and Teltrend Provisions Regarding  Limitations of Liability and
Indemnification. Westell's Amended and Restated Certificate of Incorporation and
Teltrend's Restated Certificate of Incorporation each contain provisions:

          o    eliminating the personal  liability of its directors for monetary
               damages  resulting  from breaches of their  fiduciary duty to the
               fullest extent permitted by the Delaware General Corporation Law;
               and
          o    indemnifying  its  directors  and officers to the fullest  extent
               permitted  by the Delaware  General  Corporation  Law,  including
               circumstances    in   which    indemnification    is    otherwise
               discretionary.

         Westell's  and  Teltrend's  bylaws  each  provide  that the  applicable
company will indemnify its directors and executive  officers,  and may indemnify
its other officers,  employees and other agents, to the fullest extent permitted
by law. The bylaws also permit each company to secure insurance on behalf of any
person it is required or permitted to indemnify for any liability arising out of
his or her actions in such  capacity,  regardless  of whether  the bylaws  would
permit  indemnification.  Westell and Teltrend each maintain liability insurance
for its directors and officers.

                                   CHAPTER SIX
                     ADDITIONAL INFORMATION FOR STOCKHOLDERS

                   SUBMISSION OF FUTURE STOCKHOLDER PROPOSALS

         A stockholder  proposal to be included in Westell's proxy statement and
presented  at  Westell's  2000 annual  meeting  must be  received  at  Westell's
executive  offices,  750 North Commons Drive Aurora,  Illinois 60504 by no later
than May 3,  2000 for  evaluation  as to  inclusion  in the proxy  statement  in
connection  with that  meeting.  Westell  stockholders  wishing  to  nominate  a
director or bring a proposal before the 2000 annual meeting, but not include the
proposal in Westell's proxy statement, must cause written notice of the proposal
to be received by the  secretary  of Westell at  Westell's  principal  executive
offices by no later than 60 days prior to the annual  meeting  date,  as well as
comply with  specified  provisions of Westell's  bylaws.  In order for a Westell
stockholder  to  nominate a candidate  for  director,  the  related  notice must
describe  various matters  regarding the nominee and the stockholder  giving the
notice, including such information as name, address, occupation and shares held.
In order for a Westell stockholder to bring other business before a stockholders
meeting,  the notice for the meeting must include various matters  regarding the
stockholder giving the notice and a description of the proposed business.  These
requirements are separate from and in addition to the requirements a stockholder
must meet to have a proposal included in Westell's proxy statement.

         Teltrend  will  hold an  annual  meeting  in the year  2000 only if the
merger has not  already  been  completed.  If a meeting is held,  a  stockholder
proposal to be included in  Teltrend's  proxy  statement  and  presented  at the
annual meeting must be received at Teltrend's executive offices by no later than
June  24,  2000  for  evaluation  as to  inclusion  in the  proxy  statement  in
connection with the meeting.  In addition,  under certain SEC rules, a proxy may
confer  discretionary  authority to vote on any matter in the event that,  among
other  situations,  Teltrend does not have notice of the matter at least 45 days
before the date on which  Teltrend's  proxy  materials  were mailed for the 1999
annual  meeting.  For the 2000 annual  meeting,  this date would be September 7,
2000.  This is in addition to the date for  submission of business at the annual
meeting under Teltrend's bylaws which require,  among other things,  that notice
of any matter be received by Teltrend  at its  principal  executive  offices not
less than 60 nor more than 90 days prior to the date of the meeting, except that
if less than 70 days' notice or prior public  disclosure  of the meeting date is
given or made to  stockholders,  notice of the matter  must be received no later

         that could be purchased under such option or warrant  multiplied by the
         Exchange  Ratio,  at a price per share of Parent Stock equal to the per
         share exercise price of such option or warrant  divided by the Exchange

         SECTION 3.3 EXCHANGE OF CERTIFICATES.

              (a)  From  and  after  the  Effective   Time,  each  holder  of  a
         certificate  which  immediately prior to the Effective Time represented
         issued and  outstanding  shares of Company  Common  Stock  (other  than
         shares  described  in Section  3.1(b))  shall be entitled to receive in
         exchange  therefor,   upon  surrender  thereof  to  an  exchange  agent
         reasonably  satisfactory  to  Parent  and the  Company  (the  "EXCHANGE
         AGENT"), a certificate or certificates representing the number of whole
         shares of Parent  Stock to which such  holder is  entitled  pursuant to
         Section  3.1(a),  any  dividends and  distributions  in respect of such
         shares of Parent Stock and any cash in lieu of a fractional  share,  as
         contemplated by Sections 3.3 and 3.4 hereof.  Notwithstanding any other
         provision  of this  Agreement,  (i) until  holders  or  transferees  of
         certificates  formerly representing shares of Company Common Stock have
         surrendered  them for  exchange as provided  herein,  no  dividends  or
         distributions  on shares of Parent  Stock shall be paid with respect to
         any shares of Parent Stock to which the holder of any such  certificate
         would be  entitled  pursuant  to the terms  hereof and no  payment  for
         fractional  shares shall be made and (ii)  without  regard to when such
         certificates  formerly  representing shares of Company Common Stock are
         surrendered for exchange as provided herein,  no interest shall be paid
         on any dividends or distributions or any payment for fractional shares.
         Upon  surrender  of  a  certificate  which  immediately  prior  to  the
         Effective Time  represented  issued and  outstanding  shares of Company
         Common Stock (other than shares  described  in Section  3.1(b)),  there
         shall be paid to the holder of such certificate (i) at the time of such
         surrender, the amount of any cash payable in lieu of a fractional share
         of Parent  Stock to which such holder is  entitled  pursuant to Section
         3.4 and the  amount  of any  dividends  or other  distributions  with a
         record date after the Effective Time  theretofore  paid with respect to
         the whole  shares of  Parent  Stock  issuable  upon  surrender  of such
         certificate,  and (ii) at the  appropriate  payment date, the amount of
         any  dividends  or other  distributions  with a record  date  after the
         Effective  Time  but  prior  to  such  surrender  and  a  payment  date
         subsequent to such surrender  payable with respect to such whole shares
         of Parent Stock.

              (b) If any  certificate for shares of Parent Stock is to be issued
         in  a  name  other  than  that  in  which  the   certificate   formerly
         representing  shares of Company  Common Stock  surrendered  in exchange
         therefor is registered in the Company's transfer records, it shall be a
         condition of such  exchange  that the person  requesting  such exchange
         shall pay any applicable  transfer or other taxes required by reason of
         such issuance.

              (c) As soon as practicable  after the Effective Time, Parent shall
         make  available to the  Exchange  Agent the  certificates  representing
         shares of Parent Stock required to effect the exchanges  referred to in
         paragraph  (a)  above and cash for  payment  of any  fractional  shares
         referred to in Section 3.4.

              (d) As soon as practicable  after the Effective Time, the Exchange
         Agent  shall  mail  to  each  holder  of  record  of a  certificate  or
         certificates  that immediately  prior to the Effective Time represented
         issued and  outstanding  shares of Company  Common  Stock  (other  than
         shares described in Section 3.1(b)) (the "COMPANY  CERTIFICATES") (i) a
         letter of  transmittal  (which  shall  specify that  delivery  shall be
         effected,  and risk of loss and title to the Company Certificates shall
         pass,  only upon actual  delivery of the  Company  Certificates  to the
         Exchange  Agent)  and  (ii)  instructions  for  use  in  effecting  the
         surrender  of the Company  Certificates  in exchange  for  certificates
         representing   shares  of  Parent  Stock.  Upon  surrender  of  Company
         Certificates  for  cancellation to the Exchange Agent,  together with a
         duly executed  letter of  transmittal  and such other  documents as the


<PAGE>


         Exchange  Agent shall  reasonably  require,  the holder of such Company
         Certificates  shall be  entitled  to  receive  in  exchange  therefor a
         certificate or certificates representing that number of whole shares of
         Parent  Stock into which the shares of Company  Common  Stock  formerly
         represented by the Company  Certificates so surrendered shall have been
         converted  into the right to  receive  pursuant  to the  provisions  of
         Section  3.1(a),  any cash paid in lieu of a  fractional  share and any
         dividends and  distributions  contemplated by Section  3.3(a),  and the
         Company Certificates so surrendered shall be canceled.  Notwithstanding
         the foregoing, neither the Exchange Agent nor any party hereto shall be
         liable to a holder of a Company  Certificate  for any  shares of Parent
         Stock,  dividends or distributions thereon or cash payment in lieu of a
         fractional share delivered to a public official  pursuant to applicable
         abandoned property, escheat or similar laws.

              (e)  Promptly  following  the date which is nine months  after the
         Effective  Time,  the Exchange  Agent shall deliver to Parent all cash,
         certificates  (including  any Parent Stock) and other  documents in its
         possession  relating to the  transactions  described in this Agreement,
         and the Exchange  Agent's  duties  shall  terminate.  Thereafter,  each
         holder of a Company  Certificate may surrender such Company Certificate
         to the  Surviving  Corporation  and  (subject to  applicable  abandoned
         property,  escheat and similar laws)  receive in exchange  therefor the
         Parent  Stock,  any cash  paid in lieu of a  fractional  share  and any
         dividends and distributions contemplated by Section 3.3(a), without any
         interest thereon.  Notwithstanding the foregoing,  none of the Exchange
         Agent,  Parent,  Subsidiary,  the Company or the Surviving  Corporation
         shall be liable to a holder of a Company  Certificate for any shares of
         Parent  Stock,  dividends or  distributions  thereon or cash payment in
         lieu of a fractional  share delivered to a public official  pursuant to
         applicable abandoned property, escheat or similar laws.

              (f) In the event any  Company  Certificate  shall  have been lost,
         stolen or  destroyed,  upon the making of an  affidavit of that fact by
         the person  claiming  such Company  Certificate  to be lost,  stolen or
         destroyed,  the Surviving  Corporation shall issue in exchange for such
         lost,  stolen  or  destroyed  Company   Certificate  the  Parent  Stock
         deliverable  in respect  thereof  determined  in  accordance  with this
         Article III. When authorizing such issuance in exchange  therefor,  the
         Board of Directors of the Surviving  Corporation may, in its discretion
         and as a condition precedent to the issuance thereof, require the owner
         of such  lost,  stolen or  destroyed  Company  Certificate  to give the
         Surviving  Corporation  such indemnity as it may  reasonably  direct as
         protection  against any claim that may be made  against  the  Surviving
         Corporation  with  respect to the Company  Certificate  alleged to have
         been lost, stolen or destroyed.

         SECTION  3.4  NO  FRACTIONAL  SECURITIES.   Notwithstanding  any  other
provision of this Agreement,  no fractional  shares and no certificates or scrip
for  fractional  shares of Parent Stock shall be issued in  connection  with the
Merger. In lieu of any such fractional shares,  each holder of shares of Company
Common Stock who would  otherwise  have been entitled to receive a fraction of a
share of Parent  Stock upon  surrender  of  Company  Certificates  for  exchange
pursuant to this Article III (after taking into account all Company Certificates
registered  in the name of such  holder),  shall be entitled to receive from the
Exchange  Agent a cash payment equal to such fraction  multiplied by the average
closing  price per share of  Parent  Stock on the  Nasdaq  National  Market,  as
reported  by the Wall Street  Journal,  during the 10 trading  days  immediately
preceding the Effective Time.

         SECTION  3.5  THE  CLOSING.   The  closing  (the   "CLOSING")   of  the
transactions  contemplated  by this  Agreement  shall  take  place at a location
mutually  agreeable  to  Parent  and the  Company  as  promptly  as  practicable
following the date on which the last of the conditions set forth in Article VIII
is  fulfilled  or  waived,  or at such  other  time and place as Parent  and the
Company shall agree. The date on which the Closing occurs is referred to in this
Agreement as the "CLOSING DATE."

<PAGE>



         SECTION 3.6 CLOSING OF THE COMPANY'S  TRANSFER  BOOKS. At and after the
Effective Time,  holders of Company  Certificates shall cease to have any rights
as stockholders of the Company, except for the right to receive shares of Parent
Stock  pursuant  to  Section  3.1 and the right to receive  cash for  payment of
fractional  shares  pursuant to Section 3.4. At the  Effective  Time,  the stock
transfer  books of the  Company  shall be closed  and no  transfer  of shares of
Company Common Stock which were outstanding  immediately  prior to the Effective
Time shall  thereafter  be made.  If, after the Effective  Time,  subject to the
terms  and  conditions  of  this  Agreement,   Company   Certificates   formerly
representing  shares of Company  Common  Stock are  presented  to the  Surviving
Corporation,  they shall be canceled and exchanged for shares of Parent Stock in
accordance with this Article III.

                                   ARTICLE IV

             REPRESENTATIONS AND WARRANTIES OF PARENT AND SUBSIDIARY

         Parent and  Subsidiary  each represent and warrant to the Company that,
except as set forth in the  Disclosure  Schedule dated as of the date hereof and
signed by an authorized  officer of Parent (the "PARENT  DISCLOSURE  SCHEDULE"),
each of which exceptions shall specifically identify the relevant Section hereof
to which it relates:

         SECTION  4.1  ORGANIZATION  AND  QUALIFICATION.   Each  of  Parent  and
Subsidiary  is a  corporation  duly  organized,  validly  existing  and in  good
standing under the laws of the state of its  incorporation and has the requisite
power and authority to own,  lease and operate its assets and  properties and to
carry  on  its  business  as it is now  being  conducted.  Each  of  Parent  and
Subsidiary  is  qualified  to do  business  and  is in  good  standing  in  each
jurisdiction  in which the  properties  owned,  leased or  operated by it or the
nature of the  business  conducted  by it makes  such  qualification  necessary,
except  where  the  failure  to be so  qualified  and in  good  standing  is not
reasonably  likely to, when taken together with all other such failures,  have a
Parent  Material  Adverse  Effect.  For  purposes of this  Agreement,  a "PARENT
MATERIAL  ADVERSE EFFECT" is any event,  change or effect that (i) is materially
adverse to the business, operations, properties, assets, condition (financial or
other) or  results of  operations  of Parent  and its  subsidiaries,  taken as a
whole,  other than any event,  change or effect  resulting  from (a)  changes in
general economic conditions (including United States stock market conditions) or
(b)  changes in the market  price for Parent  Stock or Company  Common  Stock as
reflected on the Nasdaq National  Market,  or (ii) prevents Parent or Subsidiary
from consummating the transactions  contemplated  hereby,  including the Merger,
prior to the date  specified in Section  9.1(b)(i)  hereof.  True,  accurate and
complete   copies  of  each  of  Parent's  and   Subsidiary's   certificate   of
incorporation  and  by-laws,  in each  case as in  effect  on the  date  hereof,
including all amendments  thereto,  have  heretofore  been made available to the
Company.

         SECTION 4.2 CAPITALIZATION.

              (a) As of the date of this Agreement, the authorized capital stock
         of Parent  consists  of (a)  65,500,000  shares of  Parent  Stock,  (b)
         25,000,000  shares of Class B Common  Stock , par value $0.01 per share
         ("PARENT CLASS B COMMON STOCK"),  and (c) 1,000,000 shares of preferred
         stock, par value $0.01 per share ("PARENT PREFERRED STOCK").  As of the
         close of business on  September  30,  1999,  (i)  17,489,521  shares of
         Parent Stock and 19,124,869  shares of Parent Class B Common Stock were
         issued and  outstanding,  (ii) no shares of Parent Preferred Stock were
         issued and outstanding, (iii) no shares of Parent Stock, Parent Class B
         Common  Stock or Parent  Preferred  Stock were held in the  treasury of
         Parent,  (iv)  4,768,304  shares  of Parent  Stock  were  reserved  for
         issuance  pursuant to the exercise of outstanding  options and warrants
         to  purchase  Parent  Stock,  (v) 131,825  shares of Parent  Stock were
         reserved for issuance under  Parent's  Employee Stock Purchase Plan and
         (vi) 19,124,869  shares of Parent Stock were reserved for issuance upon

<PAGE>


         conversion of Parent's Class B Common Stock. Between September 30, 1999
         and the date of this  Agreement,  Parent  has  issued  no shares of its
         capital  stock except for 62,836 shares of Parent Stock issued upon the
         exercise of options  granted  pursuant to Parent's 1995 Stock Incentive
         Plan. As of the date of this Agreement all outstanding shares of Parent
         Stock and Parent Class B Common Stock are, and immediately prior to the
         Effective Time all outstanding  shares of Parent Stock and Parent Class
         B Common Stock will be, validly  issued,  fully paid and  nonassessable
         and free of any preemptive (or similar) right.

              (b) The authorized  capital stock of Subsidiary  consists of 1,000
         shares of Subsidiary  Common Stock,  of which 100 shares are issued and
         outstanding,  which  shares  are  owned  beneficially  and of record by
         Parent.

              (c) Except as disclosed in the Parent Disclosure  Schedule,  as of
         the date hereof, there are no outstanding subscriptions, options, puts,
         calls,   contracts,    commitments,    understandings,    restrictions,
         arrangements,  rights or warrants, including any right of conversion or
         exchange under any outstanding security,  instrument or other agreement
         and also  including any rights plan or other  anti-takeover  agreement,
         obligating  Parent or any  subsidiary  of Parent to issue,  deliver  or
         sell, or cause to be issued,  delivered or sold,  additional  shares of
         the capital  stock of Parent or any  subsidiary of Parent or obligating
         Parent or any  subsidiary of Parent to grant,  extend or enter into any
         such  agreement or  commitment.  Except as  otherwise  disclosed in the
         Parent  Disclosure  Schedule,  there are no voting  trusts,  proxies or
         other agreements or understandings to which Parent or any subsidiary of
         Parent  is a party or by which  Parent or any  subsidiary  of Parent is
         bound with  respect  to the  voting of any  shares of capital  stock of
         Parent, and there are no registration rights or similar agreements with
         respect  to  any  shares  of  capital  stock  of  Parent  or any of its
         subsidiaries.  The shares of Parent Stock issued to stockholders of the
         Company in connection with the Merger will be duly authorized,  validly
         issued, fully paid and nonassessable and free of preemptive rights.

              (d) Except for the Parent Stock and Parent Class B Common Stock or
         as otherwise  described in the Parent Disclosure  Schedule,  Parent has
         outstanding  no  bonds,  debentures,  notes  or  other  obligations  or
         securities  the  holders  of  which  have  the  right  to vote  (or are
         convertible or exchangeable  into or exercisable for securities  having
         the right to vote) with the stockholders of Parent on any matter.

         SECTION 4.3 SUBSIDIARIES. Each direct and indirect corporate subsidiary
of Parent is duly  organized,  validly  existing and in good standing  under the
laws of its  jurisdiction  of  incorporation  and has the  requisite  power  and
authority to own,  lease and operate its assets and  properties  and to carry on
its  business  as it is now  being  conducted.  Each  subsidiary  of  Parent  is
qualified to do business, and is in good standing, in each jurisdiction in which
the  properties  owned,  leased or operated by it or the nature of the  business
conducted by it makes such qualification necessary,  except where the failure to
be so qualified  and in good standing  would not,  when taken  together with all
such other failures,  have a Parent Material Adverse Effect. Except as disclosed
in the Parent  Disclosure  Schedule,  all of the  outstanding  shares of capital
stock of each  corporate  subsidiary of Parent are validly  issued,  fully paid,
nonassessable  and  free  of  preemptive  rights,  and  are  owned  directly  or
indirectly  by  Parent,  free and clear of any  liens,  claims or  encumbrances,
except that such shares are pledged to secure Parent's credit facilities. Except
as  disclosed in the Parent  Disclosure  Schedule,  there are no  subscriptions,
options,  warrants,  rights, puts, calls,  contracts,  voting trusts, proxies or
other commitments, understandings,  restrictions or arrangements relating to the
issuance, sale, voting, transfer,  ownership or other rights with respect to any
shares of capital  stock of any corporate  subsidiary  of Parent,  including any
right of conversion or exchange under any  outstanding  security,  instrument or
agreement.


<PAGE>


         As used in this Agreement,  the term "SUBSIDIARY" shall mean, when used
with reference to any person or entity,  any corporation,  partnership,  limited
liability company,  joint venture or other entity of which such person or entity
(either acting alone or together with its other  subsidiaries) owns, directly or
indirectly,  50% or more of the stock or other voting interests,  the holders of
which  are  entitled  to vote for the  election  of a  majority  of the board of
directors  or any  similar  governing  body  of such  corporation,  partnership,
limited liability company, joint venture or other entity.

         SECTION 4.4 AUTHORITY; NON-CONTRAVENTION; APPROVALS.

              (a)  Parent  and  Subsidiary  each have full  corporate  power and
         authority  to enter  into this  Agreement  and,  subject  to the Parent
         Stockholders'  Approval  (as defined in Section  7.3(b)) and the Parent
         Required  Statutory  Approvals  (as  defined  in  Section  4.4(c)),  to
         consummate the  transactions  contemplated  hereby.  This Agreement has
         been approved by the Boards of Directors of Parent and Subsidiary,  and
         has been  approved  by a majority  of the  non-employee  members of the
         Board of Directors of Parent, and no other corporate proceedings on the
         part of Parent or  Subsidiary  are necessary to authorize the execution
         and delivery of this Agreement or, except for the Parent  Stockholders'
         Approval, the consummation by Parent and Subsidiary of the transactions
         contemplated   hereby.  This  Agreement  has  been  duly  executed  and
         delivered  by each of Parent  and  Subsidiary,  and,  assuming  the due
         authorization,   execution   and   delivery   hereof  by  the  Company,
         constitutes a valid and legally binding agreement of each of Parent and
         Subsidiary  enforceable  against  each of them in  accordance  with its
         terms,  except that such  enforcement may be subject to (i) bankruptcy,
         insolvency, reorganization,  moratorium or other similar laws affecting
         or relating to  enforcement  of  creditors'  rights  generally and (ii)
         general equitable principles.

              (b) The execution and delivery of this Agreement by each of Parent
         and Subsidiary do not and will not violate,  conflict with or result in
         a breach of any  provision  of, or  constitute  a default  (or an event
         which,  with  notice  or  lapse  of time or both,  would  constitute  a
         default)  under,  or result in the  termination  of, or accelerate  the
         performance   required  by,  or  result  in  a  right  of  termination,
         acceleration or amendment under, or result in the creation of any lien,
         security interest,  charge or encumbrance upon any of the properties or
         assets  of Parent or any of its  subsidiaries  under any of the  terms,
         conditions  or  provisions  of  (i)  the  respective   certificates  of
         incorporation or by-laws of Parent or any of its subsidiaries, (ii) any
         statute, law, ordinance,  rule,  regulation,  judgment,  decree, order,
         injunction,  writ,  permit  or  license  of any  court or  governmental
         authority  applicable  to Parent or any of its  subsidiaries  or any of
         their  respective  properties  or  assets  or  (iii)  any  note,  bond,
         mortgage,   indenture,  deed  of  trust,  license,  franchise,  permit,
         concession,   contract,  lease  or  other  instrument,   obligation  or
         agreement of any kind to which Parent or any of its subsidiaries is now
         a party or by which Parent or any of its  subsidiaries  or any of their
         respective  properties  or assets  may be bound.  The  consummation  by
         Parent and Subsidiary of the transactions  contemplated hereby will not
         result  in  any  violation,  conflict,  breach,  default,  termination,
         acceleration  or  creation  of rights or liens  under any of the terms,
         conditions or provisions  described in clauses (i) through (iii) of the
         preceding sentence, subject (x) in the case of the terms, conditions or
         provisions described in clauses (i) and (ii) above, to obtaining (prior
         to the Effective Time) the Parent Required Statutory  Approvals and the
         Parent  Stockholder's  Approval  and  (y) in  the  case  of the  terms,
         conditions or provisions  described in clause (iii) above, to obtaining
         (prior  to  the  Effective  Time)  consents  required  from  commercial
         lenders,  lessors or other  third  parties as  specified  on the Parent
         Disclosure  Schedule.  Excluded  from the  foregoing  sentences of this
         paragraph  (b),  insofar  as they  apply to the  terms,  conditions  or
         provisions described in clauses (ii) and (iii) of the first sentence of
         this paragraph (b), are such violations, conflicts, breaches, defaults,
         terminations,  accelerations or creations of liens, security interests,
         charges or encumbrances that would not, in the aggregate, have a Parent
         Material Adverse Effect.

         Delaware in connection with the Merger,  and (iv) the filings by Parent
         required in order for the Parent Stock to be issued in connection  with
         the Merger to be listed on the Nasdaq  National Market (the filings and
         approvals  referred  to in clauses (i)  through  (iv) are  collectively
         referred  to  as  the  "PARENT  REQUIRED  STATUTORY   Approvals"),   no
         declaration,   filing  or   registration   with,   or  notice   to,  or
         authorization,  consent or approval of, any  governmental or regulatory
         body or authority is necessary  for the  execution and delivery of this
         Agreement  by Parent or  Subsidiary  or the  consummation  by Parent or
         Subsidiary of the  transactions  contemplated  hereby,  other than such
         declarations, filings, registrations, notices, authorizations, consents
         or approvals which, if not made or obtained,  as the case may be, would
         not, in the aggregate, have a Parent Material Adverse Effect.

         SECTION 4.5 REPORTS AND FINANCIAL STATEMENTS. Parent has filed with the
SEC all forms,  statements,  reports and documents (including all post-effective
amendments and supplements thereto) required to be filed by it under each of the
Securities  Act,  the  Exchange  Act and the  respective  rules and  regulations
thereunder,  all of which, as amended if applicable,  complied when filed in all
material  respects with all applicable  requirements  of the appropriate act and
the rules and regulations  thereunder.  Parent has made available to the Company
copies  (including  all  exhibits,  post-effective  amendments  and  supplements
thereto) of its (a) Annual  Reports on Form 10-K for the fiscal year ended March

(b)  proxy  and  information  statements  relating  to (i) all  meetings  of its
stockholders  (whether annual or special) and (ii) actions by written consent in
lieu of a stockholders' meeting from January 1, 1997, until the date hereof, and
(c) all other reports,  including quarterly reports, and registration statements
filed by Parent  with the SEC since  January 1, 1997  (other  than  registration
statements filed on Form S-8) (the documents referred to in clauses (a), (b) and
(c) filed prior to the date hereof are  collectively  referred to as the "PARENT
SEC REPORTS").  The Parent SEC Reports are  identified on the Parent  Disclosure
Schedule.  As of  their  respective  filing  dates  (and,  in  the  case  of any
registration statement,  on the date it was declared effective),  the Parent SEC
Reports did not contain any untrue statement of a material fact or omit to state
a  material  fact  required  to be  stated  therein  or  necessary  to make  the
statements  therein,  in the light of the  circumstances  under  which they were
made,  not  misleading.   The  audited  consolidated  financial  statements  and
unaudited interim  consolidated  financial  statements of Parent included in the
Parent SEC Reports  (collectively,  the "PARENT FINANCIAL STATEMENTS") have been
prepared  in  accordance  with  United  States  generally  accepted   accounting
principles  applied on a consistent basis (except as may be indicated therein or
in the  notes  thereto)  and  fairly  present,  in all  material  respects,  the
financial  position of Parent and its  subsidiaries  as of the dates thereof and
the results of their operations and their cash flows for the periods then ended,
subject,  in the case of the unaudited interim financial  statements,  to normal
year-end and audit adjustments and any other adjustments described therein.

         SECTION 4.6 ABSENCE OF UNDISCLOSED LIABILITIES.  Except as disclosed in
the Parent SEC Reports or as contemplated by this Agreement,  neither Parent nor
any of its  subsidiaries  had at September 30, 1999, or has incurred  since that

otherwise) of any nature, except: (a) liabilities,  obligations or contingencies
(i) which are accrued or reserved against in the Parent Financial  Statements or
reflected in the notes thereto or (ii) which were incurred  after  September 30,
1999, and were incurred in the ordinary  course of business and consistent  with
past practices;  (b) liabilities,  obligations or contingencies  which (i) would
not, in the aggregate,  have a

<PAGE>

Parent  Material  Adverse  Effect,  or (ii) have been discharged or paid in full
prior to the date hereof;  and (c) liabilities  and  obligations  which are of a
nature not required to be reflected in the consolidated  financial statements of
Parent and its subsidiaries  prepared in accordance with United States generally
accepted accounting  principles  consistently applied and which were incurred in
the ordinary course of business.

         SECTION 4.7 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since the date of the
balance sheet  included in the most recently  filed Parent SEC Report (the "LAST
PARENT SEC REPORT") that contains  consolidated  financial statements of Parent,
there has not been any Parent  Material  Adverse  Effect other than changes that
affect the industries in which Parent and its subsidiaries operate generally.

         SECTION  4.8  LITIGATION.  Except as  disclosed  in the Last Parent SEC
Report,  there are no claims,  suits,  actions or proceedings pending or, to the
knowledge  of  Parent,  threatened  against  Parent or any of its  subsidiaries,
before any court, governmental department,  commission,  agency, instrumentality
or authority, or any arbitrator that seek to restrain or enjoin the consummation
of the Merger or which would  reasonably  be  expected,  either  alone or in the
aggregate  with  all  such  claims,  actions  or  proceedings,  to have a Parent
Material  Adverse  Effect.  Except as set forth in the Last  Parent SEC  Report,
neither Parent nor any of its  subsidiaries is subject to any judgment,  decree,
injunction,  rule or order of any court,  governmental  department,  commission,
agency,  instrumentality  or  authority  or any  arbitrator  which  prohibits or
restricts the consummation of the transactions contemplated hereby or would have
any Parent Material Adverse Effect.

         SECTION 4.9  REGISTRATION  STATEMENT AND PROXY  STATEMENT.  None of the
information  to be  supplied by Parent or its  subsidiaries  or  Affiliates  for
inclusion  in (a) the  Registration  Statement on Form S-4 to be filed under the
Securities  Act with the SEC by Parent in  connection  with the  Merger  for the

distributed  in connection  with the  Company's  and Parent's  meetings of their
respective  stockholders  to vote  upon  this  Agreement  and  the  transactions
contemplated  hereby (the "PROXY  STATEMENT"  and,  together with the prospectus
included in the Registration Statement, the "JOINT PROXY  STATEMENT/PROSPECTUS")
will  contain  any  untrue  statement  of a  material  fact or omit to state any
material  fact  required to be stated  therein or necessary in order to make the
statements therein, in the light of the circumstances under which they are made,
not  misleading,  at any of:  (i) the time the  Registration  Statement  (or any
amendment or supplement thereto) is declared effective;  (ii) the time the Joint
Proxy  Statement/Prospectus  (or any amendment or  supplement  thereto) is first
mailed to the stockholders of Parent and Company;  (iii) the time of each of the
meetings of the stockholders of Parent and Company to be held in connection with
the  transactions  contemplated by this Agreement;  and (iv) the Effective Time.
The Joint Proxy Statement/ Prospectus will, as of its mailing date, comply as to
form in all material respects with all applicable laws, including the provisions
of the  Securities  Act and the  Exchange  Act and  the  rules  and  regulations
promulgated  thereunder,  except  that no  representation  is made by  Parent or
Subsidiary  with  respect  to  information   supplied  by  the  Company  or  the
stockholders  of the  Company  for  inclusion  therein.  For  purposes  of  this
Agreement,  the term  "Affiliate"  means,  when used with respect to a specified
person or entity,  another person or entity that, directly or indirectly through
one or more  intermediaries,  controls or is  controlled  by or is under  common
control with the person or entity specified. For the purpose of this definition,
"control"  means (i) the  ownership  or  control  of more than 50% of the equity
interest  in any  person or entity,  or (ii) the  ability to direct or cause the
direction of the  management or affairs of a person or entity,  whether  through
the direct or indirect ownership of voting interests, by contract or otherwise.

         SECTION  4.10 NO  VIOLATION  OF LAW.  Except as  disclosed  in the Last
Parent SEC Report,  neither Parent nor any of its  subsidiaries  is in violation
of, or has been given  notice or been charged  with any  violation  of, any law,
statute,  order, rule, regulation,  ordinance,  or judgment (including,  without
limitation,

<PAGE>


any applicable  environmental  law, ordinance or regulation) of any governmental
or regulatory body or authority,  except for violations which, in the aggregate,
would not  reasonably  be expected  to have a Parent  Material  Adverse  Effect.
Except  as  disclosed  in the Last  Parent  SEC  Report,  as of the date of this
Agreement,  to the  knowledge  of  Parent,  no  investigation  or  review by any
governmental or regulatory  body or authority is pending or threatened,  nor has
any  governmental  or  regulatory  body or  authority  indicated an intention to
conduct the same,  other than, in each case,  those the outcome of which, as far
as reasonably can be foreseen,  will not have a Parent Material  Adverse Effect.
Parent and its subsidiaries have all permits, licenses,  franchises,  variances,
exemptions, orders and other governmental authorizations, consents and approvals
necessary to conduct their businesses as presently conducted (collectively,  the
"PARENT  PERMITS"),  except  for  permits,  licenses,   franchises,   variances,
exemptions, orders, authorizations, consents and approvals the absence of which,
alone or in the  aggregate,  would not have a Parent  Material  Adverse  Effect.
Parent  and its  subsidiaries  are not in  violation  of the terms of any Parent
Permit, except for delays in filing reports or violations which, alone or in the
aggregate, would not have a Parent Material Adverse Effect.

         SECTION 4.11  COMPLIANCE  WITH  AGREEMENTS.  Except as disclosed in the
Last Parent SEC Report , each of Parent and its subsidiaries is not in breach or
violation  of or in  default in the  performance  or  observance  of any term or
provision of, and no event has occurred which, with lapse of time or action by a
third party, could result in a default under (a) the respective  certificates of
incorporation,  by-laws or other similar organizational instruments of Parent or
any of its subsidiaries or (b) any contract, commitment,  agreement,  indenture,
mortgage,  loan  agreement,  note,  lease,  bond,  license,  approval  or  other
instrument to which Parent or any of its subsidiaries is a party or by which any
of them is bound or to which  any of their  properties  or assets  are  subject,
other than, in the case of clause (b) of this Section 4.11, breaches, violations
and defaults which would not have, in the aggregate,  a Parent Material  Adverse
Effect.

         SECTION 4.12 TAXES.

              (a)  Parent  and its  subsidiaries  have (i) duly  filed  with the
         appropriate  governmental  authorities  all Tax  Returns (as defined in
         Section 4.12(c)) required to be filed by them for all periods ending on
         or prior to the  Effective  Time,  other  than  those Tax  Returns  the
         failure  of which to file  would  not  have a Parent  Material  Adverse
         Effect,  and such Tax Returns  were,  as of their  respective  dates of
         filing,  true,  correct and complete in all material  respects and (ii)
         duly paid in full or made  adequate  provision  for the  payment of all
         Taxes (as defined in Section 4.12(b)) for all past and current periods.
         The  liabilities and reserves for Taxes reflected in the Parent balance
         sheet  included in the Last Parent SEC Report are adequate to cover all
         Taxes for all  periods  ending at or prior to the date of such  balance
         sheet and there is no  liability  for  Taxes for any  period  beginning
         after  such date other than  Taxes  arising in the  ordinary  course of
         business.  There are no material  liens for Taxes upon any  property or
         assets of Parent or any subsidiary thereof,  except for liens for Taxes
         not yet due. There are no unresolved  issues of law or fact arising out
         of a notice of deficiency,  proposed  deficiency or assessment from the
         Internal Revenue Service (the "IRS") or any other  governmental  taxing
         authority   with  respect  to  Taxes  of  the  Parent  or  any  of  its
         subsidiaries  which, if decided adversely,  singly or in the aggregate,
         would have a Parent Material Adverse Effect. Except as disclosed on the
         Parent  Disclosure  Schedule,  neither Parent nor its  subsidiaries has
         waived any statute of  limitations in respect of Taxes or agreed to any
         extension of time with respect to a Tax assessment or deficiency  other
         than  waivers  and  extensions  which are no longer in effect.  Neither
         Parent  nor  any of  its  subsidiaries  is a  party  to  any  agreement
         providing  for the  allocation or sharing of Taxes with any entity that
         is not, directly or indirectly,  a corporate subsidiary of Parent other
         than  agreements  the  consequences  of which are fully and  adequately
         reserved for in the Parent Financial Statements. Neither Parent nor any
         of its  corporate  subsidiaries

<PAGE>

         has,  with  regard to any assets or  property  held,  acquired or to be
         acquired by any of them,  filed a consent to the application of Section
         341(f) of the Code.

              (b) For purposes of this  Agreement,  the term "TAXES"  shall mean
         all taxes,  including,  without  limitation,  income,  gross  receipts,
         excise, property, sales, withholding, social security, occupation, use,
         service,  license,  payroll,  franchise,  transfer and recording taxes,
         fees and charges, windfall profits, severance, customs, import, export,
         employment or similar taxes, charges, fees, levies or other assessments
         imposed by the United States, or any state, local or foreign government
         or  subdivision  or agency  thereof,  whether  computed  on a separate,
         consolidated, unitary, combined or any other basis, and such term shall
         include any interest,  fines,  penalties or additional  amounts and any
         interest in respect of any additions,  fines or penalties  attributable
         or imposed or with respect to any such taxes, charges,  fees, levies or
         other assessments.

              (c) For purposes of this  Agreement,  the term "TAX RETURN"  shall
         mean any return, report or other document or information required to be
         supplied to a taxing authority in connection with Taxes.

         hereof, Parent and its subsidiaries do not maintain or contribute to or
         have any  obligation  or  liability  to or with respect to any material
         employee  benefit  plans,  programs,  arrangements  or practices  (such
         plans,   programs,   arrangements   or  practices  of  Parent  and  its
         subsidiaries  being  referred  to as  the  "PARENT  PLANS"),  including
         employee  benefit plans within the meaning set forth in Section 3(3) of
         the  Employee  Retirement  Income  Security  Act of  1974,  as  amended
         ("ERISA"),  or other similar material arrangements for the provision of
         benefits.  Neither Parent nor any of its subsidiaries  maintains or has
         any financial or funding liability with respect to any  "Multi-employer
         Plan"  within  the  meaning of  Section  3(37) of ERISA or a  "Multiple
         Employer  Plan"  within  the  meaning  of  Section  413(c) of the Code.
         Neither Parent nor any of its subsidiaries has any obligation to create
         or contribute to any  additional  such plan,  program,  arrangement  or
         practice or to amend any such plan, program, arrangement or practice so
         as to increase benefits or contributions thereunder, except as required
         under  the  terms  of  the  Parent  Plans,  under  existing  collective
         bargaining  agreements or to comply with applicable law. Neither Parent
         nor any of its  subsidiaries  has any  obligation  to contribute to any
         plan subject to Title IV of ERISA.

              (b) Except as disclosed in the Parent SEC Reports,  (i) there have
         been no  prohibited  transactions  within the meaning of Section 406 or
         407 of ERISA or  Section  4975 of the Code with  respect  to any of the
         Parent  Plans  that could  result in  penalties,  taxes or  liabilities
         which, singly or in the aggregate, could have a Parent Material Adverse
         Effect,   (ii)  each  of  the  Parent  Plans  has  been   operated  and
         administered  in all material  respects in accordance  with  applicable
         laws  during the period of time  covered by the  applicable  statute of
         limitations,  (iii) each of the Parent  Plans  which is  intended to be
         "qualified"  within the meaning of Section  401(a) of the Code has been
         determined by the Internal  Revenue Service to be so qualified and such
         determination  has not been modified,  revoked or limited by failure to
         satisfy any condition thereof or by a subsequent amendment thereto or a
         failure to amend,  except that it may be necessary  to make  additional
         amendments  retroactively  to maintain the  "qualified"  status of such
         Parent Plans, and the period for making any such necessary  retroactive
         amendments  has not expired,  (iv) to the best  knowledge of Parent and
         its  subsidiaries,   there  are  no  material  pending,  threatened  or
         anticipated  claims involving any of the Parent Plans other than claims
         for  benefits  in the  ordinary  course,  and (v) no act,  omission  or
         transaction  (individually  or in  the  aggregate)  has  occurred  with

         of Parent or any  subsidiary  under Sections 409 or 502(c)(i) or (l) of
         ERISA or Chapter 43 of Subtitle  (A) of the Code.  Each Parent Plan can
         be  unilaterally  terminated  by  Parent  or a  subsidiary  at any time
         without material liability, other than for amounts previously reflected
         in the financial  statements (or notes thereto)  included in the Parent
         SEC Reports.

              (c) The Parent SEC Reports contain a true and complete  summary or
         list of or otherwise  describe all material  employment  contracts  and

         provisions and all severance agreements with executive officers.

         and its  subsidiaries  have conducted  their  respective  businesses in

         Environmental  Law  including,  without  limitation,  any toxic  waste,
         pollutant, contaminant, hazardous substance, toxic substance, hazardous
         waste,  special  waste,   industrial  substance  or  petroleum  or  any
         derivative  or  by-product  thereof,   radon,   radioactive   material,
         asbestos,  or asbestos  containing  material,  urea  formaldehyde  foam
         insulation, lead or polychlorinated biphenyls.

         SECTION 4.16 TITLE TO ASSETS.  Parent and each of its  subsidiaries has
good and marketable  title in fee simple to all its real property and good title
to all its leasehold  interests  and other owned  properties as reflected in the
most recent balance sheet included in the Parent  Financial  Statements,  except
for such properties and assets that have been disposed of in the ordinary course
of  business  since  the  date of such  balance  sheet,  free  and  clear of all
mortgages,  liens,  pledges,  charges or encumbrances of any nature  whatsoever,
except (i) the lien for current taxes, payments of which are not yet delinquent,
(ii) such imperfections in title and easements and encumbrances,  if any, as are
not  substantial in character,  amount or extent and do not  materially  detract
from the value or interfere with the present use of the property subject thereto
or affected  thereby,  or  otherwise  materially  impair the  Parent's  business
operations  (in the  manner  presently  carried on by the  Parent),  or (iii) as
disclosed  in the Last Parent SEC  Report,  and except for such  matters  which,
singly or in the  aggregate,  could not  reasonably be expected to have a Parent
Material  Adverse  Effect.  All leases  under  which  Parent  leases any real or
personal  property are valid and effective in accordance  with their  respective
terms, and there is not, under any of such leases, any existing default or event
which  with  notice or lapse of time or both would  become a default  other than
failures to be valid and effective  and defaults  under such leases which in the
aggregate will not have a Parent Material Adverse Effect.

         SECTION  4.17  REORGANIZATION.  None of the Parent,  Subsidiary  or, to
their knowledge,  any of their Affiliates has taken or agreed or intends to take
any action or has any knowledge of any fact or

<PAGE>


circumstance  that would prevent the Merger from  constituting a  reorganization
qualifying under the provisions of Section 368(a) of the Code.

         SECTION 4.18 PARENT  STOCKHOLDERS'  APPROVAL.  The affirmative  vote of
stockholders of Parent required for approval of (i) the issuance of Parent Stock
in connection with the Merger (the "Parent Stock Issuance") is a majority of the
total  votes  cast  thereon,  in  person  or  by  proxy  at a  meeting  of  such
stockholders,  by  holders  of Parent  Stock  and  Parent  Class B Common  Stock
entitled  to vote  thereon,  voting  together  as a  single  class  and (ii) the
amendment  to Parent's  Amended and Restated  Certificate  of  Incorporation  to
increase the authorized Parent Stock to 85,000,000 shares in connection with the
Merger  (the  "Parent  Charter  Amendment")  is a  majority  of the votes of the
outstanding  shares of Parent Stock and Parent Class B Common Stock  entitled to
vote thereon, voting together as a single class.

         SECTION  4.19  BROKERS AND  FINDERS.  Except for the fees and  expenses
payable to  Goldman,  Sachs & Co.  and  Hambrecht  & Quist  LLC,  which fees are
reflected in their  respective  agreements  with Parent (a copy of each of which
has been  delivered to the  Company),  Parent has not entered into any contract,
arrangement  or  understanding  with any  person or firm which may result in the
obligation  of  Parent  to pay  any  investment  banking  fees,  finder's  fees,
brokerage or agent  commissions  or other like payments in  connection  with the
transactions contemplated hereby.

         SECTION 4.20 OPINION OF FINANCIAL  ADVISOR.  The  financial  advisor of
Parent, Goldman, Sachs & Co., has rendered a written opinion, dated December 13,
1999,  to the Board of Directors of Parent to the effect that as of December 13,
1999,  the Exchange  Ratio  pursuant to this  Agreement is fair from a financial
point of view to Parent.

         SECTION 4.21 COMPANY  STOCK.  Neither  Parent nor Subsidiary is, nor at
any time during the last three years has it been, an "interested stockholder" of
the Company as defined in Section 203 of the DGCL (other than as contemplated by
this  Agreement).  Neither Parent nor  Subsidiary  owns (directly or indirectly,
beneficially  or of  record)  or is a party  to any  agreement,  arrangement  or
understanding for the purpose of acquiring,  holding, voting or disposing of, in
each  case,  any  shares  of  capital  stock  of  the  Company  (other  than  as
contemplated by this Agreement).

         SECTION  4.22  SECTION  203.  The action of the Board of  Directors  of
Parent in approving this Agreement (and the transactions provided for herein) is
sufficient  to  render  inapplicable  to this  Agreement  (and the  transactions
provided for  herein),  in light of the Voting  Agreement,  dated as of the date
hereof,  among the  Company  and  certain of the  stockholders  of  Parent,  the
restrictions on "business  combinations" (as defined in Section 203 of the DGCL)
as set forth in Section 203 of the DGCL.

                                   ARTICLE V

                  REPRESENTATIONS AND WARRANTIES OF THE COMPANY

         The Company  represents  and  warrants to Parent and  Subsidiary  that,
except as set forth in the  disclosure  schedule dated as of the date hereof and
signed  by an  authorized  officer  of  the  Company  (the  "COMPANY  DISCLOSURE
SCHEDULE"),  each of which exceptions shall  specifically  identify the relevant
Section hereof to which it relates:

         SECTION  5.1   ORGANIZATION  AND   QUALIFICATION.   The  Company  is  a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware and has the requisite  corporate power and authority to
own, lease and operate its assets and properties and to carry on its business as
it is now being  conducted.  The Company is  qualified  to do business and is in
good standing in each  jurisdiction


<PAGE>


in which the  properties  owned,  leased or  operated by it or the nature of the
business  conducted by it makes such qualification  necessary,  except where the
failure to be so qualified  and in good  standing is not  reasonably  likely to,
when  taken  together  with all other  such  failures,  have a Company  Material
Adverse Effect.  For purposes of this  Agreement,  a "COMPANY  MATERIAL  ADVERSE
EFFECT" is any event,  change or effect  that (i) is  materially  adverse to the
business,  operations,  properties,  assets,  condition  (financial or other) or
results of  operations  of the  Company and its  subsidiaries  taken as a whole,
other than any event,  change or effect  resulting  from (a)  changes in general
economic  conditions  (including  United States stock market  conditions) or (b)
changes in the  market  price of the  Company  Common  Stock or Parent  Stock as
reflected  on the Nasdaq  National  Market,  or (ii)  prevents  the Company from
consummating the transactions  contemplated hereby,  including the Merger, prior
to the date specified in Section 9.1(a)(i) hereof.  True,  accurate and complete
copies of the Company's  Restated  Certificate of Incorporation  and Amended and
Restated  Bylaws,  in each case as in effect on the date hereof,  including  all
amendments thereto, have heretofore been delivered to Parent.

         SECTION 5.2 CAPITALIZATION.

              (a) The  authorized  capital  stock  of the  Company  consists  of
         15,000,000 shares of Company Common Stock,  1,000,000 shares of Class A
         Common  Stock,  par  value  $.01  per  share  ("COMPANY  CLASS A COMMON
         STOCK"),  and 750,000  shares of  Preferred  Stock,  par value $.01 per
         share,  of which 80,000 shares have been  designated as Series A Junior
         Participating  Preferred Stock ("COMPANY  PREFERRED STOCK").  As of the
         close of  business on  September  30,  1999,  (i)  5,779,720  shares of
         Company  Common  Stock were issued and  outstanding,  (ii) no shares of
         Company Class A Common Stock or Company Preferred Stock were issued and
         outstanding,  (iii) 735,000 shares of Company Common Stock were held in
         the treasury of the Company,  (iv) no shares of Company  Class A Common
         Stock  and no  shares  of  Company  Preferred  Stock  were  held in the
         treasury of the  Company,  (v) 929,904  shares of Company  Common Stock
         were  reserved  for issuance  pursuant to the  exercise of  outstanding
         options to purchase  Company  Common  Stock;  and (vi) 80,000 shares of
         Company  Preferred  Stock were reserved for issuance in connection with
         the rights (the "RIGHTS") to purchase shares of Company Preferred Stock
         issued pursuant to the Rights Agreement,  dated as of January 16, 1997,
         as amended  (the "RIGHTS  AGREEMENT"),  between the Company and LaSalle
         National Bank, as Rights Agent. Between September 30, 1999 and the date
         of this  Agreement,  the  Company  has issued no shares of its  capital
         stock except for 1,117  shares of Company  Common Stock issued upon the
         exercise of options  granted  pursuant to the Company  Option Plans (as
         defined below). As of the date of this Agreement all outstanding shares
         of Company  Common Stock are, and  immediately  prior to the  Effective
         Time all  outstanding  shares of Company  Common Stock will be, validly
         issued,  fully paid and  nonassessable  and free of any  preemptive (or
         similar)  right.  As used  herein,  "COMPANY  OPTION  PLANS"  means the
         following,  in each case as amended: the TI Investors Inc. Stock Option
         Plan,  Teltrend Inc.  1995 Stock Option Plan,  Teltrend Inc. 1996 Stock
         Option Plan, and Teltrend Inc. 1997 Non-Employee  Director Stock Option
         Plan.

              (b) Except as disclosed in the Company  Disclosure  Schedule,  and
         except for the Rights and the Rights  Agreement,  as of the date hereof
         there  were  no  outstanding   subscriptions,   options,  puts,  calls,
         contracts,  commitments,  understandings,  restrictions,  arrangements,
         rights or warrants, including any right of conversion or exchange under
         any  outstanding  security,  instrument  or  other  agreement  and also
         including any rights plan or other anti-takeover agreement,  obligating
         the Company or any subsidiary of the Company to issue, deliver or sell,
         or cause to be  issued,  delivered  or sold,  additional  shares of the
         capital  stock of the  Company  or any  subsidiary  of the  Company  or
         obligating  the  Company  or any  subsidiary  of the  Company to grant,
         extend or enter into any such  agreement  or  commitment.  There are no
         voting trusts,  proxies or other agreements or  understandings to which
         the  Company or any  subsidiary  of the  Company is a party or by which


<PAGE>



         Company or any  subsidiary  of  Company  is bound  with  respect to the
         voting of any  shares of capital  stock of the  Company,  although  the
         Company  has  been  advised,  as of the  date  hereof,  that all of its
         directors  and  executive  officers  intend  to  vote in  favor  of the
         adoption  of this  Agreement,  and,  except as set forth on the Company
         Disclosure  Schedule,  there  are no  registration  rights  or  similar
         agreements  with respect to any shares of capital  stock of the Company
         or any of its subsidiaries.

              (c) Except  for the  Company  Common  Stock,  options to  purchase
         Company  Common Stock  granted  under the Company  Option Plans and the
         Rights,  the Company has  outstanding  no bonds,  debentures,  notes or
         other  obligations or securities the holders of which have the right to
         vote  (or are  convertible  or  exchangeable  into or  exercisable  for
         securities  having the right to vote) with the  stockholders of Company
         on any matter.

         SECTION 5.3 SUBSIDIARIES. Each direct and indirect corporate subsidiary
of the Company is duly  organized,  validly  existing and in good standing under
the laws of its  jurisdiction of  incorporation  and has the requisite power and
authority to own,  lease and operate its assets and  properties  and to carry on
its business as it is now being  conducted.  Each  subsidiary  of the Company is
qualified to do business, and is in good standing, in each jurisdiction in which
the  properties  owned,  leased or operated by it or the nature of the  business
conducted by it makes such qualification necessary,  except where the failure to
be so qualified and in good standing will not, when taken together with all such
other failures,  have a Company Material Adverse Effect.  All of the outstanding
shares of capital stock of each corporate  subsidiary of the Company are validly
issued,  fully paid,  nonassessable  and free of preemptive rights and are owned
directly  or  indirectly  by the  Company  free and clear of any liens,  claims,
encumbrances,  security interests,  equities,  charges and options of any nature
whatsoever. There are no subscriptions,  options, warrants, rights, puts, calls,
contracts,   voting  trusts,  proxies  or  other  commitments,   understandings,
restrictions or arrangements relating to the issuance,  sale, voting,  transfer,
ownership  or other  rights with  respect to any shares of capital  stock of any
corporate  subsidiary  of the  Company,  including  any right of  conversion  or
exchange under any outstanding security, instrument or agreement.

         SECTION 5.4 AUTHORITY; NON-CONTRAVENTION; APPROVALS.

              (a) The Company has full  corporate  power and  authority to enter
         into this Agreement and, subject to the Company Stockholders'  Approval
         (as  defined in Section  7.3(a))  and the  Company  Required  Statutory
         Approvals  (as  defined  in  Section   5.4(c)),   to   consummate   the
         transactions contemplated hereby. The Board of Directors of the Company
         has at a meeting duly called and held and at which a quorum was present
         and acting  throughout,  by the affirmative vote of the majority of the
         directors of the Company,  (i)  determined  that this Agreement and the
         Merger are advisable  and in the best  interests of the Company and its
         stockholders,  (ii)  approved  this  Agreement in  accordance  with the
         provisions of the DGCL,  and (iii)  resolved,  in  accordance  with and
         subject to the terms of this Agreement,  to recommend  adoption of this
         Agreement  by  the  Company's   stockholders  and  directed  that  this
         Agreement be submitted for consideration by the Company's stockholders.
         No other corporate proceedings on the part of the Company are necessary
         to authorize the  execution  and delivery of this  Agreement or, except
         for the Company Stockholders' Approval, the consummation by the Company
         of the transactions  contemplated  hereby. This Agreement has been duly
         executed  and  delivered  by  the  Company,   and,   assuming  the  due
         authorization,  execution and delivery hereof by Parent and Subsidiary,
         constitutes  a valid and  legally  binding  agreement  of the  Company,
         enforceable  against the Company in accordance  with its terms,  except
         that such  enforcement  may be subject to (a)  bankruptcy,  insolvency,
         reorganization,  moratorium or other similar laws affecting or relating
         to enforcement of creditors' rights generally and (b) general equitable
         principles.


<PAGE>


              (b) The execution and delivery of this Agreement by the Company do
         not and will not  violate,  conflict  with or result in a breach of any
         provision of, or  constitute a default (or an event which,  with notice
         or lapse of time or both,  would constitute a default) under, or result
         in the termination  of, or accelerate the  performance  required by, or
         result in a right of termination,  acceleration or amendment  under, or
         result  in the  creation  of any  lien,  security  interest,  charge or
         encumbrance  upon any of the properties or assets of the Company or any
         of its subsidiaries under any of the terms, conditions or provisions of
         (i)   the   certificates   of   incorporation,   by-laws   or   similar
         organizational  documents  of the  Company or any of its  subsidiaries,
         (ii) any statute, law, ordinance,  rule, regulation,  judgment, decree,
         order, injunction, writ, permit or license of any court or governmental
         authority  applicable to the Company or any of its  subsidiaries or any
         of their  respective  properties  or assets,  or (iii) any note,  bond,
         mortgage,   indenture,  deed  of  trust,  license,  franchise,  permit,
         concession,   contract,  lease  or  other  instrument,   obligation  or
         agreement  of any kind to which the Company or any of its  subsidiaries
         is now a party or by which the  Company or any of its  subsidiaries  or
         any  of  their  respective  properties  or  assets  may be  bound.  The
         consummation  by the Company of the  transactions  contemplated  hereby
         will  not  result  in  any  violation,   conflict,   breach,   default,
         termination,  acceleration  or creation of liens or rights under any of
         the terms,  conditions or  provisions  described in clauses (i) through
         (iii) of the preceding sentence,  subject (x) in the case of the terms,
         conditions  or provisions  described in clauses (i) and (ii) above,  to
         obtaining (prior to the Effective Time) the Company Required  Statutory
         Approvals and the Company Stockholders' Approval and (y) in the case of
         the terms, conditions or provisions described in clause (iii) above, to
         obtaining  (prior  to  the  Effective  Time)  consents   required  from
         commercial lenders,  lessors or other third parties as specified in the
         Company Disclosure  Schedule.  Excluded from the foregoing sentences of
         this paragraph (b),  insofar as they apply to the terms,  conditions or
         provisions described in clauses (ii) and (iii) of the first sentence of
         this paragraph (b), are such violations, conflicts, breaches, defaults,
         terminations,  accelerations or creations of liens, security interests,
         charges  or  encumbrances  that  would not,  in the  aggregate,  have a
         Company Material Adverse Effect.

              (c) Except for (i) the filings by the Company required by, and the
         expiration or termination of any applicable  waiting period under,  the
         HSR Act, (ii) the filing of the Joint Proxy  Statement/Prospectus  with
         the SEC  pursuant  to the  Exchange  Act,  and (iii) the  making of the
         Merger  Filing with the  Secretary of State of the State of Delaware in
         connection  with the Merger (the filings and  approvals  referred to in
         clauses (i) through (iii) are collectively  referred to as the "COMPANY
         REQUIRED STATUTORY APPROVALS"), no declaration,  filing or registration
         with,  or notice  to, or  authorization,  consent or  approval  of, any
         governmental  or  regulatory  body or authority  is  necessary  for the
         execution  and  delivery  of  this  Agreement  by  the  Company  or the
         consummation by the Company of the  transactions  contemplated  hereby,
         other  than  such  declarations,   filings,   registrations,   notices,
         authorizations,  consents or approvals  which, if not made or obtained,
         as the  case  may be,  would  not,  in the  aggregate,  have a  Company
         Material Adverse Effect.

         SECTION  5.5 REPORTS AND  FINANCIAL  STATEMENTS.  The Company has filed
with the SEC all material forms,  statements,  reports and documents  (including
all post-effective  amendments and supplements  thereto) required to be filed by
it under each of the Securities  Act, the Exchange Act and the respective  rules
and regulations  thereunder,  all of which,  as amended if applicable,  complied
when filed in all material  respects  with all  applicable  requirements  of the
appropriate  act and the rules  and  regulations  thereunder.  The  Company  has
previously  delivered to Parent copies  (including all exhibits,  post-effective
amendments and  supplements  thereto) of its (a) Annual Reports on Form 10-K for
the year ended July 31, 1999, and for the immediately  preceding fiscal year, as
filed with the SEC,  (b) proxy and  information  statements  relating to (i) all
meetings of its  stockholders  (whether  annual or special)  and (ii) actions by
written consent in lieu of a stockholders'  meeting from January 1, 1997,  until
the date hereof, and (c) all

<PAGE>


other reports, including quarterly reports, and registration statements filed by
the  Company  with the SEC  since  January  1,  1997  (other  than  registration
statements filed on Form S-8) (the documents referred to in clauses (a), (b) and
(c) filed prior to the date hereof are collectively  referred to as the "COMPANY
SEC REPORTS").  The Company SEC Reports are identified on the Company Disclosure
Schedule.  As of  their  respective  filing  dates  (and,  in  the  case  of any
registration  statement,  the  date on  which it was  declared  effective),  the
Company SEC Reports did not contain any untrue  statement of a material  fact or
omit to state a material fact required to be stated therein or necessary to make
the statements  therein, in the light of the circumstances under which they were
made,  not  misleading.   The  audited  consolidated  financial  statements  and
unaudited interim  consolidated  financial statements of the Company included in
the Company SEC Reports (collectively,  the "COMPANY FINANCIAL STATEMENTS") have
been prepared in accordance  with United States  generally  accepted  accounting
principles  applied on a consistent basis (except as may be indicated therein or
in the  notes  thereto)  and  fairly  present,  in all  material  respects,  the
financial  position of the Company and its  subsidiaries as of the dates thereof
and the results of their  operations  and their cash flows for the periods  then
ended,  subject, in the case of the unaudited interim financial  statements,  to
normal  year-end  and  audit  adjustments  and any other  adjustments  described
therein.

         SECTION 5.6 ABSENCE OF UNDISCLOSED LIABILITIES.  Except as disclosed in
the  Company  SEC  Reports or as  contemplated  by this  Agreement,  neither the
Company nor any of its  subsidiaries had at July 31, 1999, or has incurred since
that date, any liabilities or obligations (whether absolute, accrued, contingent
or  otherwise)  of  any  nature,   except  (a)   liabilities,   obligations   or
contingencies (i) which are accrued or reserved against in the Company Financial
Statements or reflected in the notes  thereto or (ii) which were incurred  after
July 31,  1999,  and were  incurred  in the  ordinary  course  of  business  and
consistent with past practices,  (b)  liabilities,  obligations or contingencies
which (i) would not, in the aggregate, have a Company Material Adverse Effect or
(ii) have been  discharged  or paid in full  prior to the date  hereof,  and (c)
liabilities and  obligations  which are of a nature not required to be reflected
in the  consolidated  financial  statements of the Company and its  subsidiaries
prepared  in  accordance  with  United  States  generally  accepted   accounting
principles  consistently  applied and which were incurred in the ordinary course
of business.

         SECTION 5.7 ABSENCE OF CERTAIN CHANGES OR EVENTS. Since the date of the
balance sheet  included in the most recently filed Company SEC Report (the "LAST
COMPANY SEC REPORT")  that  contains  consolidated  financial  statements of the
Company,  there has not been any Company  Material  Adverse  Effect,  other than
changes  that affect the  industries  in which the Company and its  subsidiaries
operate generally.

         SECTION 5.8  LITIGATION.  Except as  disclosed  in the Last Company SEC
Report or the Company Disclosure Schedule,  there are no claims,  suits, actions
or proceedings  pending or, to the knowledge of the Company,  threatened against
the  Company  or  any  of  its  subsidiaries,  before  any  court,  governmental
department, commission, agency, instrumentality or authority, or any arbitrator,
that seek to restrain the  consummation of the Merger or which would  reasonably
be expected,  either alone or in the aggregate with all such claims,  actions or
proceedings,  to have a Company Material Adverse Effect.  Except as set forth in
the Last Company SEC Report,  neither the Company nor any of its subsidiaries is
subject  to any  judgment,  decree,  injunction,  rule or  order  of any  court,
governmental department,  commission,  agency,  instrumentality or authority, or
any  arbitrator,   which   prohibits  or  restricts  the   consummation  of  the
transactions  contemplated  hereby or would have any  Company  Material  Adverse
Effect.

         SECTION 5.9  REGISTRATION  STATEMENT AND PROXY  STATEMENT.  None of the
information to be supplied by the Company or its  subsidiaries or Affiliates for
inclusion  in (a) the  Registration  Statement or (b) the Proxy  Statement  will
contain any untrue  statement  of a material  fact or omit to state any material
fact required to be stated  therein or necessary in order to make the statements
therein,  in the light of the

<PAGE>

circumstances under which they are made, not misleading, at any of: (i) the time
the Registration  Statement (or any amendment or supplement thereto) is declared
effective; (ii) the time the Joint Proxy  Statement/Prospectus (or any amendment
or  supplement  thereto)  is first  mailed to the  stockholders  of  Parent  and
Company;  (iii) the time of each of the meetings of the  stockholders  of Parent
and Company to be held in connection with the transactions  contemplated by this
Agreement; and (iv) the Effective Time. The Joint Proxy Statement/Prospectus, as
it relates to the meeting of the Company's stockholders to be held in connection
with the transactions  contemplated hereby, will comply, as of its mailing date,
as to form in all material  respects  with all  applicable  laws,  including the
applicable  provisions of the  Securities Act and the Exchange Act and the rules
and regulations promulgated thereunder, except that no representation is made by
the Company with respect to  information  supplied by Parent,  Subsidiary or any
stockholder or Affiliate of Parent for inclusion therein.

         SECTION  5.10 NO  VIOLATION  OF LAW.  Except as  disclosed  in the Last
Company SEC  Report,  neither  the  Company  nor any of its  subsidiaries  is in
violation  of, or has been given notice or been charged with any  violation  of,
any law, statute,  order, rule,  regulation,  ordinance or judgment  (including,
without limitation,  any applicable  environmental law, ordinance or regulation)
of any  governmental  or  regulatory  body or authority,  except for  violations
which,  in the  aggregate,  could not  reasonably  be expected to have a Company
Material Adverse Effect.  Except as disclosed in the Last Company SEC Report, as
of the date of this Agreement, to the knowledge of the Company, no investigation
or review by any  governmental  or  regulatory  body or  authority is pending or
threatened,  nor has any governmental or regulatory body or authority  indicated
an intention to conduct the same, other than, in each case, those the outcome of
which,  as far as reasonably can be foreseen,  will not have a Company  Material
Adverse Effect.  The Company and its  subsidiaries  have all permits,  licenses,
franchises, variances, exemptions, orders and other governmental authorizations,
consents  and  approvals  necessary  to conduct  their  businesses  as presently
conducted (collectively,  the "COMPANY PERMITS"),  except for permits, licenses,
franchises,   variances,   exemptions,  orders,  authorizations,   consents  and
approvals  the  absence of which,  alone or in the  aggregate,  would not have a
Company  Material  Adverse Effect.  The Company and its  subsidiaries are not in
violation  of the  terms of any  Company  Permit,  except  for  delays in filing
reports or violations which, alone or in the aggregate, would not have a Company
Material Adverse Effect.

         SECTION 5.11  COMPLIANCE  WITH  AGREEMENTS.  Except as disclosed in the
Last  Company SEC Report,  each of the  Company and its  subsidiaries  is not in
breach or violation of or in default in the  performance  or  observance  of any
term or  provision  of, and no event has occurred  which,  with lapse of time or
action by a third party,  could result in a default  under,  (a) the  respective
certificates of incorporation,  by-laws or similar organizational instruments of
the  Company  or any of  its  subsidiaries  or  (b)  any  contract,  commitment,
agreement,  indenture,  mortgage,  loan agreement,  note, lease, bond,  license,
approval or other  instrument to which the Company or any of its subsidiaries is
a party or by which any of them is bound or to which any of their  properties or
assets are subject,  other than, in the case of clause (b) of this Section 5.11,
breaches,  violations  and defaults  which would not have, in the  aggregate,  a
Company Material Adverse Effect.

         SECTION  5.12 TAXES.  The Company and its  subsidiaries  have as of the
date  hereof  and will have as of the  Effective  Time (i) duly  filed  with the
appropriate  governmental  authorities  all Tax Returns  required to be filed by
them for all periods ending on or prior to the Effective Time,  other than those
Tax  Returns  the  failure  of which to file  would not have a Company  Material
Adverse Effect,  and such Tax Returns were, as of their respective filing dates,
true, correct and complete in all material respects,  and (ii) duly paid in full
or made adequate provision for the payment of all Taxes for all past and current
periods. The liabilities and reserves for Taxes reflected in the Company balance
sheet  included in the Last  Company SEC Report are  adequate to cover all Taxes
for all periods  ending at or prior to the date of such balance  sheet and there
is no liability  for Taxes for any period  beginning  after such date other than
Taxes arising in

property or asset of the Company or any subsidiary thereof, except for liens for
Taxes not yet due. There are no unresolved  issues of law or fact arising out of
a notice of deficiency,  proposed  deficiency or assessment  from the IRS or any
other governmental  taxing authority with respect to Taxes of the Company or any
of its  subsidiaries  which, if decided  adversely,  singly or in the aggregate,
would have a Company Material Adverse Effect. Except as set forth in the Company
Disclosure  Schedule,  neither the Company nor its  subsidiaries  has waived any
statute of  limitations  in respect of Taxes or agreed to any  extension of time
with respect to a Tax assessment or deficiency other than waivers and extensions
which are no longer in  effect.  Except as set forth in the  Company  Disclosure
Schedule,  neither  the Company  nor any of its  subsidiaries  is a party to any
agreement  providing for the allocation or sharing of Taxes with any entity that
is not, directly or indirectly,  a wholly-owned  corporate subsidiary of Company
other  than  agreements  the  consequences  of which are  fully  and  adequately
reserved for in the Company Financial Statements. Neither the Company nor any of
its  corporate  subsidiaries  has,  with regard to any assets or property  held,
acquired or to be acquired by any of them, filed a consent to the application of
Section 341(f) of the Code.

         material  employee benefit plans,  programs,  arrangements or practices

         subsidiaries  being  referred  to as the  "COMPANY  PLANS"),  including
         employee  benefit plans within the meaning set forth in Section 3(3) of
         ERISA,  or other  similar  material  arrangements  for the provision of
         benefits.  Neither the Company nor any of its subsidiaries maintains or
         has  any   financial   or  funding   liability   with  respect  to  any
         "Multi-employer  Plan" within the meaning of Section  3(37) of ERISA or
         "Multiple  Employer  Plan" within the meaning of Section  413(c) of the
         Code.  Neither  the  Company  nor  any  of  its  subsidiaries  has  any
         obligation  to  create  or  contribute  to any  additional  such  plan,
         program,  arrangement  or practice or to amend any such plan,  program,
         arrangement  or practice so as to  increase  benefits or  contributions
         thereunder,  except as required  under the terms of the Company  Plans,
         under  existing  collective  bargaining  agreements  or to comply  with
         applicable law. Neither the Company nor any of its subsidiaries has any

         Company  Plans that could  result in  penalties,  taxes or  liabilities
         which,  singly  or in the  aggregate,  could  have a  Company  Material
         Adverse  Effect,  (ii) each of the Company  Plans has been operated and
         administered  in all material  respects in accordance  with  applicable
         laws  during the period of time  covered by the  applicable  statute of
         limitations,  (iii) each of the  Company  Plans which is intended to be
         "qualified"  within the meaning of Section  401(a) of the Code has been
         determined by the Internal  Revenue Service to be so qualified and such
         determination  has not been modified,  revoked or limited by failure to
         satisfy any condition thereof or by a subsequent amendment thereto or a
         failure to amend,  except that it may be necessary  to make  additional
         amendments  retroactively  to maintain the  "qualified"  status of such
         Company Plans, and the period for making any such necessary retroactive
         amendments  has not expired,  (iv) to the best knowledge of the Company
         and its  subsidiaries,  there are no material  pending,  threatened  or
         anticipated claims involving any of the Company Plans other than claims
         for  benefits  in the  ordinary  course,  and (v) no act,  omission  or
         transaction  (individually  or in  the  aggregate)  has  occurred  with
         respect to any Company  Plan that has  resulted or could  result in any
         material   liability  (direct  or  indirect)  of  the  Company  or  any
         subsidiary  under  Sections 409 or 502(c)(i) or (l) of ERISA or Chapter
         43 of  Subtitle  (A) of the Code.  Except  as set forth in the  Company

         the Company SEC Reports.

              (c) The Company SEC Reports,  together with the Company Disclosure
         Schedule,  contain a true and complete  summary or list of or otherwise
         describe all material  employment  contracts and other employee benefit
         arrangements  with  "change of control" or similar  provisions  and all
         severance agreements with executive officers.

              (d) There are no agreements  which will or may provide payments to
         any officer,  employee,  stockholder,  or highly compensated individual
         which will be  "parachute  payments"  under Code  Section 280G that are
         nondeductible  to the Company or subject to tax under Code Section 4999
         for which the  Company or any ERISA  Affiliate  would have  withholding
         liability.

SEC  Reports,  (a)  there  are no  material  controversies  pending  or,  to the
knowledge of the Company, threatened between the Company or its subsidiaries and
any  representatives  of any of their  employees and (b) to the knowledge of the
Company,  there are no  material  organizational  efforts  presently  being made
involving  any of the  presently  unorganized  employees  of the  Company or its
subsidiaries,  except for such controversies and organizational  efforts, which,
singly or in the  aggregate,  could not reasonably be expected to have a Company
Material Adverse Effect.

         SECTION  5.15  ENVIRONMENTAL  MATTER.  Except as  disclosed in the Last
Company SEC Report or on the Company  Disclosure  Schedule,  (i) the Company and

         duty to the Company's  stockholders.  It is understood  and agreed that

         heretofore with respect to any Acquisition Proposals.

         received any request for nonpublic  information relating to the Company
         or its  subsidiaries in connection with an Acquisition  Proposal or for
         access  to the  properties,  books or  records  of the  Company  or any
         subsidiary  by any person or entity that informs the Board of Directors
         of the Company or such subsidiary that it is considering making, or has
         made,  an  Acquisition  Proposal.  Such notice to Parent  shall be made
         orally and in  writing  and shall  indicate  in  reasonable  detail the
         identity of the offeror and the terms and  conditions of such proposal,
         inquiry or contact.  The Company will keep Parent fully informed of the
         status and details of any such Acquisition Proposal or request.

         memoranda,  notes and other writings  prepared by Parent or the Company
         based on the  information  in such  material  shall be  destroyed  (and
         Parent  and the  Company  shall use their  respective  reasonable  best
         efforts to cause  their  respective  advisors  and  representatives  to
         similarly  destroy  their  documents,  memoranda  and notes),  and such
         destruction (and reasonable best efforts) shall be certified in writing

         required by applicable law.

         "AFFILIATE AGREEMENT") to the effect that such person will not offer to
         sell, sell or otherwise dispose of any shares of Parent Stock issued in
         connection  with the  Merger,  except,  in each  case,  pursuant  to an
         effective  registration  statement or in  compliance  with Rule 145, as
         amended from time to time, or in a transaction which, in the opinion of
         legal counsel  reasonably  satisfactory  to Parent,  is exempt from the
         registration  requirements of the Securities  Act. In addition,  Parent
         shall cause all certificates for Parent Stock to be received by the 145
         Affiliates to bear a legend substantially similar to the following:

              THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO THE
              PROVISIONS OF RULE 145  PROMULGATED  UNDER THE SECURITIES ACT
              OF  1933,  AS  AMENDED  (THE  "ACT"),  AND MAY  NOT BE  SOLD,
              TRANSFERRED OR OTHERWISE DISPOSED OF BY THE HOLDER EXCEPT (A)
              PURSUANT TO AN EFFECTIVE  REGISTRATION  STATEMENT FILED UNDER
              THE ACT AND IN COMPLIANCE WITH APPLICABLE  SECURITIES LAWS OF
              ANY STATE WITH RESPECT  THERETO,  (B) IN ACCORDANCE WITH RULE
              145(d) UNDER THE ACT, OR (C) IN ACCORDANCE WITH AN OPINION OF
              COUNSEL IN FORM AND SUBSTANCE SATISFACTORY TO THE ISSUER THAT
              AN EXEMPTION FROM SUCH REGISTRATION IS AVAILABLE.

              (b) The  Board  of  Directors  or  Compensation  Committee  of the
         Company  and Parent  will each grant all  approvals  and take all other
         actions  required  pursuant to Rules  16b-3(d) and  16b-3(e)  under the
         Exchange Act to cause the  disposition in connection with the Merger of
         Company Common Stock and Company Options (as  hereinafter  defined) and
         the  acquisition  in  connection  with the  Merger of Parent  Stock and
         options to acquire Parent Common Stock to be exempt from the provisions
         of Section  16(b) of the  Exchange  Act.  SECTION  7.5 NASDAQ  LISTING.
         Parent shall cause, at or before the Effective Time,  authorization for
         listing on the Nasdaq National Market ("NASDAQ"),  upon official notice
         of  issuance,  of the  shares  of  Parent  Stock  (i) to be  issued  in
         connection  with the Merger and (ii) to be reserved for  issuance  upon
         exercise of stock options issued in connection with the Merger.

         SECTION 7.6 EXPENSES AND FEES.

              (a)  Except  as set  forth in this  Section  7.6,  all  costs  and
         expenses   incurred  in   connection   with  this   Agreement  and  the
         transactions  contemplated  hereby shall be paid by the party incurring
         such expenses,  except that those expenses  incurred in connection with
         printing  and  filing  the Joint  Proxy  Statement/Prospectus  shall be
         shared equally by Parent and the Company.

              (b) The  Company  agrees  to  immediately  pay to  Parent a fee of
         $7,177,632 if:

                   (i) the Company  terminates this Agreement pursuant to clause
              (iii) of Section 9.1(a); or

<PAGE>


                   (ii) Parent terminates this Agreement pursuant to clause (iv)
              of Section 9.1(b); or

              (vi) of Section  9.1(b) or the Company  terminates  this Agreement
              pursuant to clause (iv)(2) of Section 9.1(a), in each case if, but
              only if, the  Company  enters  into a  definitive  agreement  with
              respect  to  an  Acquisition   Transaction   within  three  months
              following such termination.

              (c)  Parent  agrees  to  immediately  pay to the  Company a fee of
         $7,177,632 if:

                   (i) Parent terminates this Agreement pursuant to clause (vii)
              of  Section  9.1(b)  or  the  Company  terminates  this  Agreement
              pursuant to clause (vii) of Section  9.1(a) and, in each case, if,
              but  only if,  Parent  enters  into a  definitive  agreement  with
              respect  to a  Parent  Acquisition  Proposal  within  nine  months
              following such termination; or

                   (ii) Parent,  in  accordance  with Section  7.3(b),  does not
              recommend  to  its  stockholders  approval  of  the  Parent  Stock
              Issuance  and  the  Parent  Charter   Amendment  and  the  Company
              terminates  this  Agreement  pursuant to clause (iv)(1) of Section
              9.1(a), if, but only if, Parent enters into a definitive agreement
              with respect to a Parent Acquisition  Proposal within three months
              following such termination.

         SECTION 7.7 AGREEMENT TO COOPERATE.

              (a) Subject to the terms and conditions  herein provided,  each of
         the parties hereto shall use all  reasonable  efforts to take, or cause
         to be taken,  all  action  and to do, or cause to be done,  all  things
         necessary, proper or advisable under applicable laws and regulations to
         consummate and make  effective the  transactions  contemplated  by this
         Agreement,  including  using  its  reasonable  efforts  to  obtain  all
         necessary  or  appropriate  waivers,  consents  or  approvals  of third
         parties   required   in  order   to   preserve   material   contractual
         relationships  of the Company and its  subsidiaries,  all  necessary or
         appropriate waivers, consents and approvals and SEC "no-action" letters
         to effect all necessary  registrations,  filings and submissions and to
         lift any  injunction  or other  legal bar to the Merger  (and,  in such
         case, to proceed with the Merger as expeditiously as possible).

              (b) Without  limitation of the  foregoing,  each of Parent and the
         Company  undertakes and agrees to file as soon as practicable after the
         date hereof a  Notification  and Report Form under the HSR Act with the
         Federal Trade Commission (the "FTC") and the Antitrust  Division of the
         Department of Justice (the  "ANTITRUST  DIVISION").  Each of Parent and
         the  Company  shall  (i)  use  its  reasonable  efforts  to  comply  as
         expeditiously  as possible  with all lawful  requests of the FTC or the
         Antitrust  Division for additional  information  and documents and (ii)
         not  extend  any  waiting  period  under the HSR Act or enter  into any
         agreement with the FTC or the Antitrust  Division not to consummate the
         transactions  contemplated  by this  Agreement,  except  with the prior
         written consent of the other parties hereto.

              (c) In the event any  litigation is commenced  against the Company
         by any person or entity  relating to the  transactions  contemplated by
         this  Agreement,  including any Acquisition  Transaction,  Parent shall
         have the right,  at its own expense,  to participate  therein,  and the
         Company  will not settle any such  litigation  without  the  consent of
         Parent,  which  consent will not be  unreasonably  withheld or delayed;
         provided,  however, that nothing contained in this Section 7.7(c) shall
         be  construed  as  granting  Parent a right to consent to a  particular
         settlement,  if the  Company's  Board of Directors  determines  in good
         faith after  consultation with the Company's outside legal counsel that


<PAGE>


         the existence or exercise of such right with respect to that particular
         settlement would violate the fiduciary duties of the Company's Board of
         Directors.

              (d) Parent shall reasonably consider taking such actions as may be
         useful in resolving any antitrust  objections that may be asserted with
         respect to the transactions  contemplated by this Agreement by the FTC,
         the Antitrust Division or any other federal or state agency.

         SECTION 7.8 Each party  hereto  shall  consult  with each other  before
issuing any press release or otherwise  issuing any other similar written public
statement  with respect to this  Agreement or the Merger and shall not issue any
such press release or make any such public  statement  without the prior consent
of each  other  party,  which  consent  shall not be  unreasonably  withheld  or
delayed;  provided,  however, that a party may, without the prior consent of any
other  party,  issue  such a press  release  or  other  similar  written  public
statement  as may be required by law or any  listing  agreement  with a national
securities  exchange  or market to which  Parent or the Company is a party if it
has used all  reasonable  efforts to consult with such other party and to obtain
such other  party's  consent  but has been  unable to do so in a timely  manner.
Further,  the parties  shall use their  respective  reasonable  best  efforts to
coordinate  and jointly  schedule and  interface  with the various  governmental
authorities  and  other  applicable  regulatory  bodies  involved  or  otherwise
interested in the transactions contemplated by this Agreement.

         SECTION 7.9 OPTION PLANS.

              (a) Prior to the Effective Time, the Company and Parent shall take
         such action as may be necessary to cause each unexpired and unexercised
         option to  purchase  shares of Company  Common  Stock  (each a "COMPANY
         Option") to be  automatically  converted at the Effective  Time into an
         option (each a "PARENT  OPTION") which will be (1) to purchase a number
         of shares  of Parent  Stock  equal to the  number of shares of  Company
         Common Stock that could have been  purchased  under the Company  Option
         multiplied by the Exchange  Ratio, at a price per share of Parent Stock
         equal to the option exercise price  determined  pursuant to the Company
         Option divided by the Exchange  Ratio and (2) otherwise  subject to the
         same terms and conditions as the Company  Option;  provided that (i) if
         the applicable  agreement  evidencing  the Company Option  provides for
         acceleration  of vesting of such  Company  Option upon the Merger,  the
         converted stock option will be so vested following the Merger and, (ii)
         the terms of the Company Options  outstanding  under the Company's 1997
         Non-Employee  Director  Stock Option Plan shall be amended so that such
         options may be  exercised  (A) with  respect to those  directors of the
         Company who do not become directors of Parent, until the earlier of (x)
         six months  following the  Effective  Time or (y) the date on which the
         options expire in accordance with their terms,  and (B) with respect to
         those  directors of the Company who are  appointed  directors of Parent
         pursuant to Section 2.4, until the earlier of (x) 90 days following the
         date on which such persons  cease to be directors of Parent and (y) the
         date on which the options  expire in accordance  with their terms.  The
         date of grant of a substituted Parent Option shall be the date on which
         the  corresponding  Company Option was granted.  At the Effective Time,
         all references in the Company Options to the Company shall be deemed to
         refer to Parent.  Parent shall assume all of the Company's  obligations
         with respect to Company Options as so amended and shall, from and after
         the Effective  Time,  make  available for issuance upon exercise of the
         Parent  Options all shares of Parent Stock  covered  thereby and, at or
         prior to the Effective Time, amend its  Registration  Statement on Form
         S-8 or file a new registration statement to cover the additional shares
         of Parent Stock subject to Parent  Options  granted in  replacement  of
         Company  Options.  Following  the Effective  Time,  Parent will use all
         reasonable  efforts to  maintain  the  effectiveness  of the  foregoing
         registration   statement  (and  maintain  the  current  status  of  the
         prospectus or prospectuses contained therein) for so long as any of the
         converted Company Options remain outstanding and unexercised.

<PAGE>

              (b) As soon as practicable  after the Effective Time, Parent shall
         deliver  to the  holders of Company  Options  immediately  prior to the
         Effective  Time  appropriate  notices  setting  forth (1) such holders'
         rights pursuant to the respective Company Options, and (2) stating that
         the  Company  Options  have  been  converted  into  Parent  Options  as
         contemplated  herein and have been assumed by Parent and shall continue
         in effect on the same terms and conditions  (subject to the adjustments
         required by this Section to give effect to the Merger).

              (c) The  holders  of  Company  Options  immediately  prior  to the
         Effective Time, and their respective legal  representatives  and heirs,
         shall be deemed third-party beneficiaries of this Section 7.9.

         SECTION  7.10  NOTIFICATION  OF CERTAIN  MATTERS.  Each of the Company,
Parent and Subsidiary  agrees to give prompt notice to each other of, and to use
their respective  reasonable best efforts to prevent or promptly remedy, (i) the
occurrence  or failure to occur or the  impending or  threatened  occurrence  or
failure to occur,  of any event  which  occurrence  or failure to occur would be
likely to cause any of its representations or warranties in this Agreement to be
untrue or inaccurate in any material respect at any time from the date hereof to
the Effective  Time and (ii) any material  failure on its part to comply with or
satisfy any covenant, condition or agreement to be complied with or satisfied by
it hereunder;  provided,  however,  that the delivery of any notice  pursuant to
this  Section 7.10 shall not limit or  otherwise  affect the remedies  available
hereunder to the party receiving such notice.

         SECTION 7.11 DIRECTORS' AND OFFICERS' INDEMNIFICATION.

              (a) From and after the Effective  Time, the Surviving  Corporation
         shall  indemnify  and hold  harmless all past and present  officers and
         directors of the Company (the "COVERED PARTIES") to the same extent and
         in the same manner and  subject to the same limits as such  persons are
         indemnified as of the date of this Agreement by the Company pursuant to
         the DGCL, the Company's  Certificate of  Incorporation or the Company's
         By-Laws for acts or omissions  occurring  at or prior to the  Effective
         Time.

              (b) The Certificate of Incorporation  and By-laws of the Surviving
         Corporation  shall contain,  and Parent shall cause the  Certificate of
         Incorporation  and  By-laws of the  Surviving  Corporation  to contain,
         provisions  no  less   favorable   with  respect  to   indemnification,
         advancement   of  expenses  and   exculpation  of  present  and  former
         directors,  officers,  employees  and  agents  of the  Company  and its
         subsidiaries  than are presently set forth in the Restated  Certificate
         of  Incorporation,  as amended,  and Amended and Restated Bylaws of the
         Company.

              (c)  The  Surviving  Corporation  shall  use its  reasonable  best
         efforts to provide, and Parent shall cause the Surviving Corporation to
         use its  reasonable  best efforts to provide,  for a period of not less
         than 6  years  from  the  Effective  Time,  one  or  more  policies  of
         directors' and officers'  liability  insurance that provide(s) coverage
         for events  occurring prior to the Effective Time (the "D&O INSURANCE")
         that is/are substantially  similar to the Company's existing policy or,
         if substantially equivalent insurance coverage is unavailable, the most
         similar available coverage;  provided,  however, that in no event shall
         the Surviving  Corporation be required to pay an annual premium for the
         D&O  Insurance in excess of 150% of the last annual  premium paid prior
         to the date hereof (the "MAXIMUM  PREMIUM").  If the Company's existing
         insurance  expires,  is  terminated  or canceled  during such  six-year
         period or exceeds the Maximum Premium, the Surviving  Corporation shall
         obtain, and Parent shall cause the Surviving  Corporation to obtain, as
         much  directors' and officers'  liability  insurance as can be obtained
         for the  remainder  of such  period for an  annualized  premium  not in
         excess  of the  Maximum  Premium,  on  terms  and  conditions  no

<PAGE>

         less advantageous to the Covered Parties than  the  Company's  existing
         directors' and officers' liability insurance.

              (d) In addition to the indemnification and advancement of expenses
         provisions set forth herein, in the event that (i) the  indemnification
         or advancement of expenses to be provided by the Surviving  Corporation
         in accordance with Section 7.11(a) or 7.11(b) above,  together with the
         D&O  Insurance  to  be  maintained  by  the  Surviving  Corporation  in
         accordance with Section 7.11(c) above,  after each is fully  exhausted,
         is not adequate to fully  indemnify or provide  advancement of expenses
         to any  Covered  Party to the same  extent and in the same  manner that
         such  indemnification  or  advancement  of  expenses  would  have  been
         required to be provided by the Company prior to the Effective Time, and
         (ii) there has been a diminution of the net book value of the Surviving
         Corporation  from the net book value of the Company as reflected on the
         balance  sheet  included in the Last  Company  SEC Report,  then Parent
         shall indemnify such Covered Party to the extent of such diminution.

              (e) Notwithstanding anything herein to the contrary, if any claim,
         action, suit,  proceeding or investigation  (whether arising before, at
         or after the Effective  Time) is made against any Covered Party,  on or
         prior to the sixth anniversary of the Effective Time, the provisions of
         this Section 7.11 shall continue in effect until the final  disposition
         of such claim, action, suit, proceeding or investigation.

              (f) The covenants contained in this Section are intended to be for
         the  benefit  of,  and shall be  enforceable  by,  each of the  Covered
         Parties and their respective heirs and legal  representatives and shall
         not be deemed exclusive of any other rights to which a Covered Party is
         entitled, whether pursuant to law, contract or otherwise.

              (g) In the event that Parent, the Surviving  Corporation or any of
         their respective  successors or assigns (i) consolidates with or merges
         into any other  person  and shall not be the  continuing  or  surviving
         corporation or entity of such consolidation or merger or (ii) transfers
         or conveys all or substantially all of its properties and assets to any
         person,  then, and in each such case, proper provision shall be made so
         that the successors or assigns of Parent, the Surviving  Corporation or
         any of their  respective  successors  or  assigns,  as the case may be,
         shall succeed to the obligations set forth in this Section 7.11.

         SECTION 7.12  CERTAIN  BENEFITS.  At the  Effective  Time,  Parent will
assume,  and, subject to Parent's right to thereafter amend, modify or terminate
the Policy in accordance with its terms, Parent will thereafter pay, perform and
discharge  when  due,  all of the  Company's  obligations  under  the  Company's
Executive Officer Severance Plan, as amended (the "POLICY"), with respect to the
individuals  who participate in the Policy (the  "PARTICIPANTS").  A copy of the
Policy and a list of the  Participants  is attached  to the  Company  Disclosure
Schedule.  With respect to those  Participants  who become employed by Parent or
any of its  subsidiaries  in connection  with the Merger,  all references in the
Policy  to the  "Company"  shall be deemed to be  references  to Parent  and its
subsidiaries,  each such  Participant  shall be an "Executive"  for all purposes
under  the  Policy  and  such  Participants'  service  to the  Company  and  its
subsidiaries  prior to the Merger shall be included in  determining  their total
years of  services  for  purposes  of the Policy.  The  Participants,  and their
respective legal  representatives and heirs, shall be third-party  beneficiaries
of this Section  7.12.  Prior to the Effective  Time,  the Company shall use its
reasonable  best  efforts to amend the options to acquire  Company  Common Stock
which are held by  Participants  so that the  provisions  of Section  2.6 of the
Policy are reflected in such options.

         SECTION  7.13  SEC  REPORTS.   The  parties   agree  that   whenever  a
representation  or warranty  contained in this  Agreement is made subject to any
fact or circumstance referenced, disclosed, set forth or described in either the
Parent SEC Reports or the Company SEC Reports (collectively, the "SEC REPORTS"),
such  representation  or warranty shall be subject only to those matters that it
is reasonably apparent from a reading of such SEC Reports would apply thereto.

                                   CONDITIONS

              (d) the  Registration  Statement  shall have become  effective  in
         accordance with the provisions of the Securities Act, and no stop order
         suspending  such  effectiveness  shall  have been  issued and remain in

                        TERMINATION, AMENDMENT AND WAIVER

         SECTION 9.1  TERMINATION.  This Agreement may be terminated at any time
prior to the Closing Date,  whether before or after adoption by the stockholders
of the  Company or Parent,  by the mutual  written  consent of the  Company  and
Parent or as follows:

              (a) The Company shall have the right to terminate this Agreement:

                   (i) if the Merger is not  completed  by June 30, 2000 (unless
              due to a delay or default on the part of the  Company),  provided,
              however,  that such date shall be extended to  September  30, 2000
              if, as of June 30,  2000,  the  parties  are  engaged  in  ongoing
              discussions  with  the FTC or  Antitrust  Division  regarding  the
              transactions contemplated hereby;

                   (ii) if the Merger is enjoined by a final, unappealable court
              order  not  entered  at the  request  or with the  support  of the
              Company and if the Company shall have used  reasonable  efforts to
              prevent the entry of such order;

                   (iii) if (A) the Company  receives an offer or proposal  from
              any Potential  Acquirer  (excluding any director or officer of the
              Company  or any  group of which any  director  or  officer  of the
              Company is a member) with respect to a merger, sale of substantial
              assets or other business  combination  involving the Company,  (B)
              the  Company's  Board of Directors  determines,  in good faith and
              after  consultation with an independent  financial  advisor,  that
              such offer or  proposal  (if  consummated  pursuant  to its terms)
              would result in an Acquisition  Transaction  more favorable to the
              Company's stockholders than the Merger (any such offer or proposal
              being referred to as a "SUPERIOR PROPOSAL") and resolves to accept
              such Superior Proposal and (C) the Company shall have given Parent
              two days'  prior  written  notice of its  intention  to  terminate
              pursuant  to  this  provision;   provided,   however,   that  such
              termination  shall not be effective until such time as the payment
              required by Section 7.6(b) shall have been received by Parent;


<PAGE>


                   (iv) if (1) the  stockholders  of Parent  fail to approve the
              Parent Stock Issuance and Parent Charter  Amendment at a duly held
              meeting of stockholders called for such purpose or any adjournment
              thereof or (2) the  stockholders of the Company fail to adopt this
              Agreement at a duly held meeting of  stockholders  called for such
              purpose or any adjournment thereof;

                   (v) if the representations and warranties of the Parent shall
              fail to be true and correct in all material  respects on and as of
              the date made or,  except in the case of any such  representations
              and  warranties  made  as of a  specified  date,  on and as of any
              subsequent  date as if made at and as of such  subsequent date and
              such failure  shall not have been cured in all  material  respects
              within 30 days after  written  notice of such  failure is given to
              the Parent by the Company;

                   (vi) if Parent (A) fails to perform in any  material  respect
              any of its material  covenants in this  Agreement and (B) does not
              cure such  default in all material  respects  within 30 days after
              notice of such default is given to Parent by the Company; or

                   (vii) if the Board of Directors of Parent shall have resolved
              to accept a Parent Superior Proposal.

              (b) Parent shall have the right to terminate this Agreement:

                   (i) if the  representations  and  warranties  of the  Company
              shall fail to be true and correct in all material  respects on and
              as  of  the  date  made  or,  except  in  the  case  of  any  such
              representations and warranties made as of a specified date, on and
              as of any subsequent  date as if made at and as of such subsequent
              date and such  failure  shall not have been cured in all  material
              respects  within 30 days after  written  notice of such failure is
              given to the Company by Parent;

                   (ii) if the Merger is not  completed by June 30, 2000 (unless
              due to a delay or  default  on the part of Parent or  Subsidiary),
              provided,  however,  that such date shall be extended to September
              30,  2000 if, as of June 30,  2000,  the  parties  are  engaged in
              ongoing  discussions with the FTC or Antitrust  Division regarding
              the transactions contemplated hereby;

                   (iii) if the  Merger  is  enjoined  by a final,  unappealable
              court  order not  entered at the  request  or with the  support of
              Parent or  Subsidiary  and if Parent  shall  have used  reasonable
              efforts to prevent the entry of such order;

                   (iv) if the Board of  Directors  of the  Company  shall  have
              resolved to accept a Superior  Proposal or shall have  recommended
              to the  stockholders  of the Company that they tender their shares
              in a  tender  or an  exchange  offer  commenced  by a third  party
              (excluding  any  affiliate  of  Parent  or any  group of which any
              affiliate of Parent is a member);

                   (v) if the  Company  (A)  fails to  perform  in any  material
              respect any of its material  covenants in this  Agreement  and (B)
              does not cure such default in all material respects within 30 days
              after notice of such default is given to the Company by Parent;

                   (vi) if the  stockholders  of the Company  fail to adopt this
              Agreement at a duly held meeting of  stockholders  called for such
              purpose or any adjournment thereof; or


<PAGE>


                   (vii) if (A) Parent receives a Parent  Acquisition  Proposal,
              which proposal  expressly  states in writing that it is subject to
              Parent terminating this Agreement or to otherwise not consummating
              the  transactions  contemplated  hereby,  (B) as a result thereof,
              Parent's  Board  of  Directors  does  not  recommend  to  Parent's
              stockholders  approval  of the Parent  Stock  Issuance  and Parent
              Charter  Amendment  in reliance  on the third  sentence of Section
              7.3(b) hereof, and (C) Parent's Board of Directors determines,  in
              good faith and after  consultation  with an independent  financial
              advisor,  that such offer or proposal (if consummated  pursuant to
              its  terms)  would  result  in a  transaction  more  favorable  to
              Parent's  stockholders than the Merger (any such offer or proposal
              being referred to as a "PARENT SUPERIOR PROPOSAL") and resolves to
              accept such Parent Superior Proposal.

         SECTION 9.2 EFFECT OF TERMINATION.  In the event of termination of this
Agreement by either Parent or the Company  pursuant to the provisions of Section
9.1, this Agreement  shall  forthwith  become void and there shall be no further
obligation on the part of the Company,  Parent,  Subsidiary or their  respective
officers or  directors  (except as set forth in this  Section 9.2, in the second
sentence of Section  7.1(a) and in Sections  7.1(b) and 7.6,  all of which shall
survive the  termination).  Nothing in this Section 9.2 shall  relieve any party
from liability for any willful or intentional breach of this Agreement.

         SECTION 9.3  AMENDMENT.  This  Agreement  may not be amended  except by
action taken by the parties'  respective  Boards of Directors or duly authorized
committees thereof and then only by an instrument in writing signed on behalf of
each of the parties hereto and in compliance with applicable law. Such amendment
may take place at any time prior to the Closing  Date,  whether  before or after
approval by the  stockholders  of the Company,  Parent or Subsidiary;  provided,
however,  that after any such  approval,  there shall not be made any  amendment
that by law  requires  the further  approval of such  stockholders  without such
further approval.

         SECTION 9.4 WAIVER. At any time prior to the Effective Time, subject to
applicable  law, the parties hereto may (a) extend the time for the  performance
of any of the obligations or other acts of the other parties  hereto,  (b) waive

Board of Directors
Westell Technologies, Inc.
750 N. Commons Drive
Aurora, IL 60504

Gentlemen:

You have requested our opinion as to the fairness from a financial point of view
to  Westell  Technologies,  Inc.  (the  "Company")  of the  exchange  ratio (the
"Exchange  Ratio") of 3.30 shares of Class A Common  Stock,  par value $0.01 per
share (the "Company Shares"),  of the Company to be exchanged by the Company for
each share of Common Stock,  par value $0.01 per share (the "Teltrend  Shares"),
of Teltrend  Inc.  ("Teltrend")  pursuant to the  Agreement  and Plan of Merger,
dated as of December  13,  1999,  by and among the  Company,  Theta  Acquisition
Corp., a wholly owned subsidiary of the Company, and Teltrend (the "Agreement").

Goldman, Sachs & Co., as part of its investment banking business, is continually
engaged in the valuation of businesses and their  securities in connection  with
mergers  and  acquisitions,  negotiated  underwritings,   competitive  biddings,
secondary  distributions of listed and unlisted  securities,  private placements
and valuations for estate,  corporate and other  purposes.  We are familiar with
the Company having acted as its financial advisor in connection with, and having
participated in certain of the negotiations leading to, the Agreement.  Goldman,
Sachs & Co. provides a full range of financial advisory and securities  services
and,  in the  course of its  normal  trading  activities,  may from time to time
effect transactions and hold securities, including derivative securities, of the
Company or Teltrend for its own account and for the accounts of customers.

We understand that SoundView  Technology Group, Inc.  ("SoundView") is acting as
financial advisor to Teltrend in connection with the transaction contemplated by
the Agreement.  SoundView and Wit Capital Group,  Inc. ("Wit") have entered into
an agreement pursuant to which Wit will acquire SoundView.  Goldman, Sachs & Co.
currently owns approximately  16.5% of the outstanding shares of common stock of
Wit and warrants to acquire  additional  shares of common stock of Wit which, if
exercised,  would result in Goldman,  Sachs & Co. owning  approximately 24.7% of
the outstanding shares of common stock of Wit.

In  connection  with this opinion,  we have  reviewed,  among other things,  the
Agreement;  Annual  Reports to  Stockholders  and Annual Reports on Form 10-K of
Teltrend  and of the Company  for the five fiscal  years ended July 31, 1999 and
the four fiscal  years  ended  March 31,  1999,  respectively;  certain  interim
reports to stockholders  and Quarterly  Reports on Form 10-Q of Teltrend and the
Company;  certain  other  communications  from Teltrend and the Company to their
respective  stockholders;  and certain internal financial analyses and forecasts
for Teltrend  and the Company  prepared by the  managements  of Teltrend and the
Company, including certain cost savings and operating synergies projected by the
management  of the Company to result from the  transaction  contemplated  by the

<PAGE>


Agreement (the  "Synergies").  We also have held discussions with members of the
senior  management of Teltrend and the Company regarding their assessment of the
strategic  rationale  for,  and  the  potential  benefits  of,  the  transaction
contemplated  by the  Agreement  and the past and current  business  operations,
financial  condition  and future  prospects of their  respective  companies.  In
addition,  we have  reviewed  the  reported  price and trading  activity for the
Teltrend Shares and the Company  Shares,  compared  certain  financial and stock
market  information  for Teltrend and the Company with similar  information  for
certain other  companies the securities of which are publicly  traded,  reviewed
the  financial   terms  of  certain   recent   business   combinations   in  the
telecommunications  equipment,  data  communications  and networking  industries
specifically and in other industries  generally and performed such other studies
and analyses as we considered appropriate.

We have relied upon the accuracy and  completeness  of all of the  financial and
other  information  discussed  with or  reviewed  by us and  have  assumed  such
accuracy  and  completeness  for  purposes of rendering  this  opinion.  In that
regard,  we have  assumed,  with  your  consent,  that  the  internal  financial
forecasts prepared by the managements of Teltrend and the Company, including the
Synergies,  have  been  reasonably  prepared  on a  basis  reflecting  the  best
currently  available  estimates and  judgments of Teltrend and the Company,  and
that the Synergies will be realized in the amounts and time periods contemplated
thereby. In addition, we have not made an independent evaluation or appraisal of
the  assets  and  liabilities  of  Teltrend  or the  Company  or  any  of  their
subsidiaries  and we have  not  been  furnished  with  any  such  evaluation  or
appraisal.  We also have assumed that all material  governmental,  regulatory or
other consents and approvals  necessary for the  consummation of the transaction
contemplated  by the Agreement  will be obtained  without any adverse  effect on
Teltrend or the Company or on the benefits of the  transaction  contemplated  by
the  Agreement.  Our  advisory  services  and the opinion  expressed  herein are
provided for the  information  and  assistance  of the Board of Directors of the
Company in connection with its consideration of the transaction  contemplated by
the Agreement,  and such opinion does not constitute a recommendation  as to how
any holder of Company Shares should vote with respect to such transaction.

Based upon and subject to the  foregoing and based upon such other matters as we
consider  relevant,  it is our opinion  that as of the date hereof the  Exchange
Ratio  pursuant to the  Agreement is fair from a financial  point of view to the
Company.

Very truly yours,


/s/ Goldman, Sachs & Co.

(GOLDMAN, SACHS & CO.)

Board of Directors
Teltrend Inc.
620 Stetson Avenue
St. Charles, IL 60174

Ladies and Gentlemen:

         We  understand  that  Westell  Technologies,  Inc.  ("Westell"),  Theta
Acquisition  Corp., a wholly owned  subsidiary of Westell  ("Merger  Sub"),  and
Teltrend Inc.  ("Teltrend" or the "Company")  are  considering  entering into an
agreement  and  plan of  merger  substantially  in the form of the  draft  dated
December 13, 1999 (the "Draft Merger Agreement")  pursuant to which, among other
things,  Merger Sub shall be merged with and into the  Company in a  transaction
(the "Merger") in which each share of common stock, par value $.01 per share, of
the Company,  subject to the conditions and  limitations  set forth in the Draft
Merger  Agreement,  shall be  converted  into  the  right  to  receive,  without
interest,  3.3 shares (the  "Exchange  Ratio") of the Class A Common Stock,  par
value $0.01 per share,  of Westell.  The terms and  conditions of the Merger are
set forth in more detail in the Draft Merger Agreement, a copy of which has been
furnished to us.

         You  have  requested  our  opinion  as  investment  bankers  as to  the
fairness, from a financial point of view, to the stockholders of the Company, of
the Exchange Ratio.

         In  conducting  our  analysis  and arriving at our opinion as expressed
herein, we have, among other things:

               (i)  reviewed the Draft Merger  Agreement and the specific  terms
                    of the Merger set forth therein;

               (ii) reviewed the draft Voting Agreement dated December 13, 1999;

               (iii)reviewed Teltrend's financial and operating  information for
                    the two-year  period ended July 31, 1999 and the three-month
                    period ended October 30, 1999;

               (iv) reviewed Westell's  financial and operating  information for
                    the two-year  period ended March 31, 1999 and the  six-month
                    period ended September 30, 1999;

               (v)  reviewed certain information regarding the private placement
                    by Westell of 6%  Subordinated  Convertible  Debentures  and
                    Stock Purchase  Warrants to Capital Ventures  International,
                    Castle Creek  Technology  Partners LLC, and Marshall Capital
                    Management, Inc.;

               (vi) reviewed   certain   financial  and  operating   information
                    regarding the business, operations and prospects of Teltrend
                    and Westell,  including forecasts and projections,  provided
                    to us  by  the  managements  of  the  Company  and  Westell,
                    respectively;

               (vii)reviewed certain publicly available  information  concerning
                    certain other  companies we deemed to be reasonably  similar
                    to the  Company  and  Westell  and the  trading  markets for
                    certain of such companies' securities;


<PAGE>

               (viii) reviewed the financial terms of certain recent mergers and
                    acquisitions that we deemed relevant;

               (ix) conducted   discussions   with  certain  members  of  senior
                    management  of the  Company  and  Westell  concerning  their
                    respective  businesses  and  operations,   assets,   present
                    condition and future prospects; and

               (x)  performed such other analyses,  examinations and procedures,
                    reviewed such other agreements and documents, and considered
                    such other factors as we have deemed,  in our sole judgment,
                    to be  necessary,  appropriate  or  relevant  to render  the
                    opinion set forth herein.

         In arriving at our opinion,  we have not made,  obtained or assumed any
responsibility for any independent evaluation or appraisal of the properties and
facilities or of the assets and liabilities  (contingent or otherwise) of either
the  Company or  Westell.  We have  assumed  and relied  upon the  accuracy  and
completeness  of the  financial and other  information  supplied to or otherwise
used by us in arriving at our opinion and have not  attempted  independently  to
verify, or undertaken any obligation to verify such information. We have further
relied upon the assurances of the  managements of Teltrend and Westell that they
were not aware of any facts  that  would  make such  information  inaccurate  or
misleading.  In addition,  we have assumed that the  forecasts  and  projections
provided  to  SoundView  Technology  Group,  Inc.  by  Westell  and the  Company
represent the best currently  available estimates and judgments of Westell's and
the Company's  managements as to the future  financial  condition and results of
operations of Westell and the Company,  respectively, and have assumed that such
forecasts and projections have been reasonably  prepared based on such currently
available  estimates and judgments.  We assume no responsibility for and express
no view as to such forecasts and  projections  or the  assumptions on which they
are based.

         We have also taken into  account our  assessment  of general  economic,
market and financial conditions and our experience in similar  transactions,  as
well as our  experience  in  securities  valuation  in  general.  Our opinion is
necessarily based upon conditions as they exist and can be evaluated on the date
hereof.

         We do not express any view as to the price at which the Company's stock
will trade prior to the closing of the Merger,  or the price at which  Westell's
stock will trade  prior to or  subsequent  to the  closing of the  Merger.  This
letter is for the  benefit and use of the Board of  Directors  of the Company in
its   consideration   of  the  Merger.   This  letter  does  not   constitute  a
recommendation of the Merger over any other alternative  transactions  which may
be  available  to the  Company  and does not  address  the  underlying  business
decision of the Board of  Directors of the Company to proceed with or effect the
Merger.

         We have,  in the  past,  provided  financial  advisory  and  investment
banking  services for the Company and have  received  fees for the  rendering of
such  services.  In the  ordinary  course of our  business,  we may trade in the
equity securities of the Company for our own account and for the accounts of our
customers  and,  accordingly,  may at any time hold a long or short  position in
such securities.  The Company has agreed to indemnify us for certain liabilities
that may arise out of the rendering of this opinion.

         Based  upon  and  subject  to  the  foregoing,  it is  our  opinion  as
investment  bankers that, as of the date hereof,  the Exchange Ratio pursuant to
the Draft  Merger  Agreement  is fair,  from a financial  point of view,  to the
Company's stockholders.
                                           Very truly yours,


                                           /s/ SoundView Technology Group, Inc.

                                           SoundView Technology Group, Inc.

                   INFORMATION NOT REQUIRED IN THE PROSPECTUS


ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS


         Under  Delaware law, a corporation  may indemnify any person who was or
is a party or is  threatened  to be made a party  to an  action  (other  than an
action by or in the right of the  corporation)  by  reason of his  service  as a
director,  officer, employee or agent of the corporation, or his service, at the
corporation's  request,  as a  director,  officer,  employee or agent of another
corporation or other enterprise,  against expenses  (including  attorneys' fees)
that are actually and reasonably  incurred by him  ("Expenses"),  and judgments,
fines and amounts paid in settlement  that are actually and reasonably  incurred
by him in connection  with the defense or  settlement  of such action,  provided
that he acted in good faith and in a manner he  reasonably  believed to be in or
not  opposed  to the  corporation's  best  interests  and,  with  respect to any
criminal  action or  proceeding,  had no  reasonable  cause to believe  that his
conduct was unlawful.  Although  Delaware law permits a corporation to indemnify
any person referred to above against  Expenses in connection with the defense or
settlement of an action by or in the right of the corporation,  provided that he
acted in good  faith  and in a manner  he  reasonably  believed  to be in or not
opposed to the  corporation's  best  interests,  if such  person has been judged
liable to the corporation,  indemnification is only permitted to the extent that
the Court of Chancery (or the court in which the action was brought)  determines
that,  despite  the  adjudication  of  liability,  such  person is  entitled  to
indemnity for such Expenses as the court deems proper.  The  determination as to
whether  a person  seeking  indemnification  has met the  required  standard  of
conduct is to be made (1) by a  majority  vote of  disinterested  members of the
board of  directors  even  though less than a quorum,  or (2) by a committee  of
disinterested  directors  designated by a majority vote of such directors,  even
though  less than a quorum,  or (3) by  independent  legal  counsel in a written
opinion,  if  there  are no  disinterested  directors  or if  the  disinterested
directors so direct, or (4) by the stockholders.  The General Corporation Law of
the State of Delaware also provides for mandatory indemnification of any present
or former  director  or officer  against  Expenses to the extent such person has
been  successful  in any  proceeding  covered by the statute.  In addition,  the
General   Corporation  Law  of  the  State  of  Delaware  provides  the  general
authorization of advancement of a director's,  officer's, employee's and agent's
litigation  expenses  and  that  indemnification  and  advancement  of  expenses
provided by the statute  shall not be deemed  exclusive  of any other  rights to
which those seeking  indemnification  or advancement of expenses may be entitled
under any bylaw, agreement or otherwise.

         Westell's  Amended  and  Restated   Certificate  of  Incorporation  and
Westell's Amended and Restated By-laws provide for  indemnification of Westell's
directors,  officers,  employees  and other  agents to the  fullest  extent  not
prohibited by the Delaware law.

         Westell maintains  liability insurance for the benefit of its directors
and officers.

ITEM 22. UNDERTAKINGS

         (a)  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 foregoing  provisions,  or otherwise,
the   Registrant  has  been  advised  that  in  the  opinion  of  the  SEC  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.

         (b) 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) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of a
prospectus  which is a part of this  Registration  Statement,  by any  person or
party who is deemed to be an underwriter  within the meaning of Rule 145(c), the
issuer  undertakes that such reoffering  prospectus will contain the information
called for by the  applicable  registration  form with respect to reofferings by
persons who may be deemed  underwriters,  in addition to the information  called
for by the other items of the applicable form.

         (d) The Registrant undertakes that every prospectus:  (i) that is filed
pursuant to paragraph (c) immediately  preceding,  or (ii) that purports to meet

business  except as  otherwise  provided  by  statute or by the  certificate  of
incorporation;  provided,  however, that with respect to any matter on which any

quorum for  purposes of such  matter.  If,  however,  such  quorum  shall not be

office  until the next  annual  election  and until  their  successors  are duly
elected and shall qualify, unless sooner displaced. If there are no directors in
office,  then an election  of  directors  may be held in the manner  provided by
statute.

                  Section 3. General  Powers.  The  business of the  corporation
shall be managed by its board of directors which may exercise all such powers of
the  corporation and do all such lawful acts and things as are not by statute or

without other notice than such resolution.

                  Section 6. Special Meetings. Special meetings of the board may
be called by the  chairman of the board or the  president on one day's notice to
each director,  either  personally or by mail or by telegram;  special  meetings

business and the act of 80% of the directors present at any meeting duly held at
which a quorum  is  present  shall be the act of the  board of  directors.  If a
quorum  shall not be  present  at any  meeting  of the  board of  directors, the
directors  present  thereat may adjourn the meeting  from time to time,  without
notice other than announcement at the meeting, until a quorum shall be present.

chairman of the board, the president, or the secretary of the corporation.  Such
resignation  shall  take  effect  at the time  specified  therein;  and,  unless
tendered to become  effective only upon  acceptance  thereof,  the acceptance of
such resignation shall not be necessary to make it effective.

                  Section 9.  Removal.  At any meeting of the  stockholders  any
director or  directors  may be removed from office,  without  assignment  of any
reason therefor, by a majority of the voting power entitled to vote in elections
of directors.

the  certificate  of  incorporation  or these  by-laws,  any action  required or
permitted  to be taken  at any  meeting  of the  board  of  directors  or of any
committee thereof may be taken without a meeting, if all members of the board or
committee,  as the case may be, consent  thereto in writing,  and the writing or
writings are filed with the minutes of proceedings of the board or committee.

                  Section  11.   Presumption  of  Assent.   A  director  of  the
corporation  who is  present  at a meeting  of the board of  directors  at which
action on any corporate  matter is taken shall be conclusively  presumed to have
assented to the action taken unless his dissent  shall be entered in the minutes
of the meeting or unless he shall file his  written  dissent to such action with
the person acting as the secretary of the meeting before the adjournment thereof
or shall  forward  such  dissent  by  registered  mail to the  secretary  of the
corporation  immediately  after the  adjournment  of the meeting.  Such right to

directors or a stated salary as a director.  No such payment shall  preclude any
director  from  serving the  corporation  in any other  capacity  and  receiving
compensation therefor.  Members of special or standing committees may be allowed
like compensation for attending committee meetings.

                  Section 12. The Assistant Secretary.  The assistant secretary,

directors,  at its regular meetings, or when the board of directors so requires,
an account of all his  transactions as treasurer and of the financial  condition

the faithful  performance of the duties of his office and for the restoration to
the corporation,  in the case of his death,  resignation,  retirement or removal
from  office,  of all  books,  papers,  vouchers,  money and other  property  of

                  Section 14. The Assistant Treasurer.  The assistant treasurer,
or if there  shall be more  than  one,  the  assistant  treasurers  in the order
determined by the board of directors (or if there be no such determination, then

the event of his  inability  or refusal to act,  perform the duties and exercise
the powers of the  treasurer  and shall  perform such other duties and have such

                                   ARTICLE VI

               CERTIFICATES OF STOCK, TRANSFERS, AND RECORD DATES

                  Section 1. Form of Certificates.  Every holder of stock in the
corporation  shall be entitled to have a certificate,  signed by, or in the name
of the corporation  by, the board of directors,  or the chairman of the board or
the president or a vice-president  and the treasurer or an assistant  treasurer,
or the secretary or an assistant  secretary of the  corporation,  certifying the
number of shares owned by him in the  corporation.  If the corporation  shall be
authorized  to issue more than one class of stock or more than one series of any
class,  the  powers,  designation,   preferences  and  relative,  participating,
optional or other  special  rights of each class of stock or series  thereof and
the  qualifications,  limitations or  restrictions  of such  preferences  and/or
rights  shall  be set  forth  in full or  summarized  on the face or back of the
certificate  which the corporation shall issue to represent such class or series
of stock,  provided  that,  except as  otherwise  provided in Section 202 of the
Delaware General Corporation Law, in lieu of the foregoing  requirements,  there
may be set forth in full or  summarized  on the face or back of the  certificate
which the corporation  shall issue to represent such class or series of stock, a
statement that the corporation  will furnish without charge to each  stockholder
who  so  requests   the  powers,   designations,   preferences   and   relative,
participating, optional or other special rights of each class of stock or series
thereof and the qualifications,  limitations or restrictions of such preferences
and/or rights.

                  Section  2.  Facsimile  Signatures.  Where  a  certificate  is
countersigned  (1)  by a  transfer  agent  other  than  the  corporation  or its
employee, or (2) by a registrar other than the corporation or its employee,  any
other  signature  on the  certificate  may be  facsimile.  In case any  officer,
transfer agent or registrar who has signed or whose facsimile signature has been
placed upon a certificate  shall have ceased to be such officer,  transfer agent
or  registrar  before  such  certificate  is  issued,  it may be  issued  by the
corporation  with the same effect as if he were such officer,  transfer agent or
registrar at the date of issue.

                  Section  3.  Lost  Certificates.  The board of  directors  may
direct  a new  certificate  or  certificates  to  be  issued  in  place  of  any
certificate or certificates  theretofore  issued by the  corporation  alleged to
have been lost,  stolen or  destroyed,  upon the making of an  affidavit of that
fact by the  person  claiming  the  certificate  of stock to be lost,  stolen or
destroyed. When authorizing such issue of a new certificate or certificates, the
board of directors may, in its  discretion  and as a condition  precedent to the
issuance  thereof,   require  the  owner  of  such  lost,  stolen  or  destroyed
certificate or certificates, or his legal representatives, to advertise the same
in such manner as it shall require and/or to give the corporation a bond in such
sums it may direct to  indemnify  against any claim that may be made against the
corporation with respect to the certificate alleged to have been lost, stolen or
destroyed.

                  Section  4.   Transfers  of  Stock.   Upon  surrender  to  the
corporation or the transfer agent of the corporation of a certificate for shares
duly endorsed or  accompanied by proper  evidence of  succession,  assignment or
authority to transfer,  it shall be the duty of the  corporation  to issue a new
certificate  to the person  entitled  thereto,  cancel the old  certificate  and
record the transaction upon its books.

                  Section 5. Fixing Record Date.  In order that the  corporation
may determine the  stockholders  entitled to notice of or to vote at any meeting
of stockholders or any adjournment  thereof,  or to express consent to corporate
action in  writing  without a meeting,  or  entitled  to receive  payment of any
dividend  or other  distribution  or  allotment  of any  rights,  or entitled to
exercise any rights in respect or any change, conversion or exchange of stock or
for the purpose of any other lawful  action,  the board of directors may fix, in
advance,  a record  date,  which  shall not be more than sixty nor less than ten
days  before  the date of such  meeting,  nor more than  sixty days prior to any
other action. A determination of stockholders of record entitled to notice of or
to vote at a meeting  of  stockholders  shall  apply to any  adjournment  of the
meeting;  provided,  however,  that the board of directors  may fix a new record
date for the adjourned meeting.

                  Section 6. Registered  Stockholders.  The corporation shall be
entitled to recognize the exclusive right of a person registered on its books as
the owner of shares to receive dividends, and to vote as such owner, and to hold
liable for calls and  assessments a person  registered on its books as the owner
of shares,  and shall not be bound to recognize  any equitable or other claim to
or interest in such share or shares on the part of any other person,  whether or
not it shall have express or other notice thereof,  except as otherwise provided
by the Delaware General Corporation Law.

                                   ARTICLE VII

                               GENERAL PROVISIONS

                  Section 1. Dividends.  Dividends upon the capital stock of the
corporation,  subject to the provisions of the certificate of incorporation,  if
any,  may be  declared  by the board of  directors  at any  regular  or  special
meeting,  pursuant to law.  Dividends  may be paid in cash,  in property,  or in
shares of the  corporation's  capital  stock,  subject to the  provisions of the
certificate of incorporation.  Before payment of any dividend,  there may be set
aside out of any funds of the  corporation  available for dividends  such sum or
sums as the directors  from time to time, in their  absolute  discretion,  think
proper  as a  reserve  or  reserves  to meet  contingencies,  or for  equalizing
dividends,  or for repairing or maintaining any property of the corporation,  or
for such other purpose as the  directors,  in their absolute  discretion,  think
proper,  and the  directors may modify or abolish any such reserve in the manner
in which it was created.

                  Section 2.  Checks.  All checks or demands for money and notes
of the  corporation  shall be signed by such  officer or  officers or such other
person or persons as the board of directors may from time to time designate.

                  Section 3. Fiscal  Year.  The fiscal year of the  corporation,
unless otherwise  provided by resolution of the board of directors,  shall begin
on the  first day of April in each year and end on the last day of March in each
year.

                  Section 4. Seal. The corporate seal shall be inscribed thereon
with the name of the corporation and the words "Corporate  Seal,  Delaware." The
seal may be used by causing it or a facsimile thereof to be impressed or affixed
or reproduced or otherwise.

                  Section  5. Stock in Other  Corporations.  Shares of any other
corporation  which  may  from  time to time be held by this  corporation  may be
represented and voted at any meeting of shareholders of such  corporation by the
chairman of the board, president or vice-president, or by any proxy appointed in
writing by the  chairman  of the board,  president  or a  vice-president  of the
corporation, or by any other person or persons thereunto authorized by the board
of directors.  Shares  represented by  certificates  standing in the name of the
corporation  may be endorsed for sale or transfer in the name of the corporation
by the chairman of the board,  president or any  vice-president  or by any other
officer or  officers  thereunto  authorized  by the board of  directors.  Shares
belonging to the corporation need not stand in the name of the corporation,  but
may be held for the benefit of the  corporation  in the  individual  name of the
treasurer or of any other  nominee  designated  for that purpose by the board of
directors.

                                  ARTICLE VIII

                                 INDEMNIFICATION

                  Section 1. Indemnification. (a) Each person who was or is made
a party or is threatened  to be made a party to or is otherwise  involved in any
action,  suit  or  proceeding,   whether  civil,  criminal,   administrative  or
investigative (hereinafter a "proceeding"), by reason of the fact that he or she
is or was a director or officer of the  corporation  or is or was serving at the
request of the corporation as a director,  officer, employee, agent or fiduciary
of  another  corporation  or of a  partnership,  joint  venture,  trust or other
enterprise,  including  service with respect to employee benefit plans,  whether
the basis of such  proceeding  is alleged  action in an  official  capacity as a
director, officer, employee or agent or in any other capacity while serving as a
director,  officer, employee or agent, shall be indemnified and held harmless by
the  corporation  to the  fullest  extent  authorized  by the  Delaware  General
Corporation  Law, as the same exists or may  hereafter be amended  (but,  in the
case of any such amendment,  only to the extent that such amendment  permits the
corporation to provide  broader  indemnification  rights than such law permitted
the  corporation  to provide  prior to such  amendment),  against  all  expense,
liability and loss (including  attorneys' fees,  judgments,  fines, ERISA excise
taxes or  penalties  and  amounts  paid in  settlement)  reasonably  incurred or
suffered by such person in connection therewith and such  indemnification  shall
continue  as to a person who has ceased to be a director,  officer,  employee or
agent  and  shall  inure  to the  benefit  of his or her  heirs,  executors  and
administrators;  provided, however, that, except as provided in paragraph (B) of
Article EIGHTH of the corporation's certificate of incorporation with respect to
proceedings  to  enforce  rights  to  indemnification,   the  corporation  shall
indemnify  any such person in  connection  with a proceeding  (or part  thereof)
initiated  by  such  person  only if  such  proceeding  (or  part  thereof)  was
authorized  by  the  board  of  directors  of  the  corporation.  The  right  to
indemnification  conferred in this Section  shall be a contract  right and shall
include  the  right  to be paid by the  corporation  the  expenses  incurred  in
defending  any such  proceeding in advance of its final  disposition;  provided,
however,  that, if the Delaware General Corporation Law requires, an advancement
of expenses incurred by a person in his or her capacity as a director or officer
(and not in any other  capacity  in which  service  was or is  rendered  by such
person,  including,  without  limitation,  service to an employee  benefit plan)
shall be made only upon delivery to the corporation of an undertaking,  by or on
behalf of such director or officer, to repay all amounts so advanced if it shall
ultimately  be  determined  that the  director or officer is not  entitled to be
indemnified  under this Section or otherwise.  The corporation may, by action of
its board of directors, grant rights to indemnification,  and to the advancement
of expenses,  to employees and agents of the  corporation  to the fullest extent
and with the same  scope and  effect as the  foregoing  indemnification  of, and
advancement of expenses to, directors and officers.

                  (b) The right to  indemnification  and the payment of expenses
incurred in defending a proceeding in advance of its final disposition conferred
in this  Section  shall not be exclusive of any other right which any person may
have or hereafter  acquire under any statute,  provision of the  certificate  of
incorporation,   by-laws,  agreement,  vote  of  stockholders  or  disinterested
directors or otherwise.

                  (c) The corporation may maintain insurance, at its expense, to
protect itself and any director,  officer,  employee or agent of the corporation
or another corporation,  partnership,  joint venture,  trust or other enterprise
against any expense,  liability or loss,  whether or not the  corporation  would
have the power to indemnify such person against such expense,  liability or loss
under Delaware law.

                  (d) Any amendment,  repeal or modification of any provision of
this Section by the  stockholders or the directors of the corporation  shall not
adversely  affect  any right or  protection  of a  director  or  officer  of the
corporation existing at the time of such amendment, repeal or modification.

                                   ARTICLE IX

                                   AMENDMENTS

                  These  by-laws  may be  altered,  amended or  repealed  or new
by-laws may be adopted by the  stockholders  or by the board of directors at any
regular  meeting  of the board of  directors  or of the  stockholders  or at any
special meeting of the board of directors or of the  stockholders,  if notice of
such  alteration,  amendment,  repeal or adoption of new by-laws be contained in
the notice of such special meeting of the stockholders.



                                                                    Exhibit 23.1
