                                                   ------
Teleconferencing, Inc., a Colorado corporation ("Secured Party").
                                                 -------------

                                    RECITALS

         A.       Secured Party has accepted a promissory note in the amount of
$347,875 (the "Note") as full consideration for a loan to Debtor, pursuant to a
               ----
resolution by the Board of Directors of even date herewith.

         B.       In order to induce Secured Party to accept the Note, Debtor
has executed and delivered a this Security Agreement.

                                    AGREEMENT

         NOW, THEREFORE, for and in consideration of the mutual covenants and
agreements contained herein, and other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, Debtor and Secured
Party hereby agree as follows:

                  1.       Grant of Security Interest.  Subject to the terms
                           --------------------------
and provisions contained herein, Debtor hereby grants to Secured Party a
security interest in all tangible personal property and receivables in which
Debtor holds an ownership interest (the "Collateral").

                  2.       Covenants and Agreements of Debtor.  Debtor hereby
                           ----------------------------------
covenants and agrees:

                           (a)      to promptly pay all taxes and  assessments
         of every nature which may be levied or assessed against the Collateral.

                           (b)      to maintain and preserve ownership of the
         Collateral.

                           (c)      to not transfer or attempt to transfer any
         interest in such Collateral.

                           (d)      from time to time to execute such additional
         documents and take such other action as Secured Party may deem
         necessary to effectuate, maintain and preserve its security interest
         in the Collateral and the perfection of the same and shall indemnify
         Secured Party from and against all reasonable costs and expenses
         incurred in connection therewith, including reasonable attorneys'
         fees.  Without limitation on the generality of the foregoing, to the
         extent any of the Collateral or proceeds therefrom constitutes cash
         or other property for which a security interest under the Colorado
         Uniform Commercial Code may be perfected only by possession, upon
         written request
<PAGE>

         from Secured Party, Debtor shall forthwith deliver the same to
         Secured Party upon Debtor's receipt thereof.

                  3.       Events of Default. The following shall constitute
                           -----------------
"Events of Default" hereunder, and each such Event of Default shall also
 -----------------
constitute an Event of Default under the Note, entitling Secured Party to
exercise all or any of the remedies available to Secured Party under the terms
of the Note and this Agreement:

                           (a)      Any default by Debtor under the Note,
         including the failure by Debtor to pay any sum when due and payable
         under the Note; or

                           (b)      The failure of Debtor to perform or observe,
         or other breach of, any other covenant, obligation, agreement,
         condition, prohibition, representation, warranty or any other term or
         provision hereunder.

                  4.       Cure by Secured Party. Debtor agrees that Secured
                           ---------------------
Party shall have the right, but not the obligation, to take any action
reasonably necessary to maintain, protect and preserve the Collateral. The
amount due under the Note shall be increased by any amounts so paid by Secured
Party. Payment or action by the Secured Party under this Section 4 shall not be
deemed to cure any default by Debtor under the Note or this Agreement.

                  5.       Secured Party's Right Upon an Event of Default.
                           ----------------------------------------------

                           (a)      Upon the occurrence of an Event of Default
         hereunder, Secured Party shall have all of the remedies of a secured
         party under the Uniform Commercial Code as enacted by the State of
         Colorado and then in effect. Without limiting the foregoing, Secured
         Party shall be entitled to recover all of its costs and expenses
         incurred in enforcing its rights hereunder and under the Note,
         including reasonable attorneys' fees and costs.

                           (b)      For any Collateral which constitutes
         proceeds resulting from liquidated proceeds or sums of any nature,
         Secured Party may, without being obligated to sell or attempt to sell
         any Collateral, giving rise to the proceeds or sums, collect such
         proceeds or sums from the Debtor and apply the same in reduction of
         the indebtedness secured hereby in such order and manner as Secured
         Party shall determine in its discretion. Debtor hereby authorizes any
         such account debtor or obligor to perform for Secured Party upon
         receiving notice from Secured Party that it is entitled to such
         performance, regardless of any dispute between Debtor and Secured
         Party concerning the existence of the requisite Event of Default or
         any other matter, and the Debtor hereby releases any such debtor or
         obligor from any liability for so performing. In connection
         therewith, such indebtedness shall be reduced only to the extent that
         such liquidated sums are actually received and actually applied by
         Secure Party as aforesaid.

                           (c)      The rights and remedies of Secured Party
         hereunder are cumulative and are not in lieu of, but are in addition
         to, any other rights or remedies which Secured Party may have under the
         Note, at law or in equity.

                           ------------------
such other documents and perform such other acts as may be deemed necessary or
appropriate by Secured Party to perfect, protect or enforce the rights
hereunder.

                  7.       Binding Effect.  The provisions of this Agreement
                           --------------
