Prospectus dated November 8, 1996
On March 7, 1997, Conolog Corporation (the "Company") announced that it
plans a public offering of 380,000 shares of a new cumulative, non-convertible,
voting 8% Preferred Stock (with a possible additional 57,000 shares of Preferred
Stock subject to over-allotment option). The Company also plans to register
1,200,000 preferred stock purchase warrants of selling securityholders and
reserve an identical amount of underlying Preferred Stock in the proposed
registration.
It is anticipated that the new shares will have one vote per share voting
together with the Common Stock. The dividend on the new Preferred Stock may be
payable at the Company's option, in Commmon Stock with a limit of 32,000 shares
per year.
The Company is in the process of selecting an underwriter for this
offering but has not yet signed a letter of intent. The terms of the Preferred
Stock are subject to negotiation with any underwriter which is selected. A
registration statement relating to these securities has not yet been filed with
the Securities and Exchange Commission.
