--------------------------------------------------------------------------------

A.

In February and May 2001, Fonix advanced an aggregate of $400,000 to Audium as a
bridge loan under the terms of a promissory note (the “Audium Note”) entered
into in conjunction with the Purchase Agreement (defined below).  The Audium
Note is convertible into shares of Audium Series A Convertible Preferred Stock
(“Audium Preferred Stock”).  Fonix has not converted any amount of the Audium
Note into shares of Audium Preferred Stock.  Payment of the Audium Note is
secured by certain of Audium’s intellectual property (the “Audium IP”) pursuant
to a Security Agreement entered into in conjunction with the Audium Note (the
"Audium Security Agreement").  Further, Audium granted to Fonix a fully paid,
worldwide, non-exclusive license to Audium’s software to make, manufacture, and
use the software and any derivative works if Audium declares bankruptcy or
ceases to do business (the  “Audium License”).

B.

In April 2001, Fonix and Audium entered into a Stock Purchase Agreement (as
amended or modified (including waivers) through the date of the execution of
this Settlement Agreement, the “Purchase Agreement”), wherein Fonix agreed to
purchase up to $2,800,000 of Audium Preferred Stock at a price of $1.46 per
share.  At closing, Fonix paid $200,000 in cash and gave Audium a non-interest
bearing promissory note (the “Fonix Note”) for the remaining $2,600,000 and
executed a Security Agreement in favor of Audium secured by the Audium Preferred
Stock (the "Fonix Security Agreement").  Each share of Audium Preferred Stock is
convertible into one share of Audium’s common stock.  Fonix has not converted
any Audium Preferred Stock into common stock.  The Purchase Agreement also
entitles Fonix to elect one member of Audium’s board of directors pursuant to a
Voting Agreement (the "Voting Agreement") entered into in conjunction with the
Purchase Agreement.  

C.

At closing of the Purchase Agreement, Audium issued 14 Audium Preferred Stock
certificates to Fonix, each certificate for 136,986 shares, and delivered one
certificate in exchange for the initial payment of $200,000.  The remaining
certificates were held by Audium as collateral for the Fonix Note under the
terms of the Fonix Security Agreement.  For each payment of $200,000 or multiple
payments that aggregate $200,000, Audium agreed to release to Fonix one
certificate for 136,986 shares of Audium Preferred Stock.  

D.

Through December 31, 2003, payments amounting to $1,800,000 had been made under
the Purchase Agreement and Audium had delivered nine certificates to Fonix.  At
December 31, 2003, the outstanding balance due under the Fonix Note was
$1,000,000 and Audium continues to hold five certificates.

E.

Audium and Fonix also have certain rights and obligations pursuant to an Amended
and Restated First Refusal and Co-Sale Agreement (the "First Refusal Agreement")
and a Registration Rights Agreement (herein so called) entered into at the time
of the Purchase Agreement, and Fonix holds certain rights, solely as a holder of
Audium Preferred Stock, pursuant to the Certificate of Designation (the
"Certificate") relating to the Audium Preferred Stock.

F.

interests under and in connection with the Purchase Agreement, the Audium Note,
the Fonix Note, the Certificate, the Audium Security Agreement, the Fonix
Security Agreement, the Voting Agreement, the First Refusal Agreement and the
Registration Rights Agreement (collectively, the "Transaction Documents"), and
