  Jeff Herrmann

  TELULAR ANNOUNCES MANDATORY CONVERSION OF PREFERRED STOCK

  VERNON HILLS, IL-October 18, 1999-Telular Corporation (Nasdaq: WRLS) today
  announced that the 11,350 outstanding shares of its 5% Series A Convertible
  Preferred Stock will automatically convert into an aggregate of
  approximately 2.1 million shares of common stock today.  The preferred stock
  converts into common stock at a post-split fixed price of $8.00 per common
  share plus accrued dividends paid in the form of approximately 700,000 shares
  of common stock valued at the weighted average closing bid price of common
  stock for the 30 consecutive days preceding conversion.

  Following the conversion of the Series A Preferred Stock into common stock,
  Telular will have approximately 11.7 million shares of common stock
  outstanding.

  The company has received a notice from two holders of preferred stock, NP
  Partners and Olympus Securities, Ltd., that they are disputing Telular's
  calculation of the number of shares of common stock to which they are
  entitled, on the grounds that the conversion price floor contained in the
  Certificate of Designations does not apply on the mandatory conversion date.
  The company does not agree with this interpretation, and has so indicated to
  those holders.  Although NP Partners and Olympus Securities have not
  indicated the number of additional shares to which they believe they are
  entitled, the company has calculated that if the conversion price floor did
  not apply, they and the other holders would be entitled to an aggregate of
  approximately 3.4 million additional shares.
