assert  a claim  or  cause of  action  when  such a claim  or  cause of  action,
otherwise meeting the prerequisites of the previous sentence, is asserted by any
Releasor against the Lender in legal or equitable proceedings  instituted by any
Releasor,  the  Lender,  or any third  party.  Anything  herein to the  contrary
notwithstanding,  this Mutual  Limited  Release  will not extend to and will not

other Loan Documents or with respect to claims accruing or arising in respect of
acts, omissions or events after the date of this Agreement.

all other persons and entities to whom any of the  Releasors  would be liable if
such persons or entities  were found to be liable to the Lender from any and all
manner of action and actions, cause and causes of action, counterclaims,  suits,
debts,  dues,  sums of money,  accounts,  covenants,  contracts,  controversies,

nature relating to, arising out of or in connection with the Loan Documents,  or
in any way  connected  with  the  Lender,  including  but not  limited  to acts,
omissions  to  act,  negotiations,  discussions  and  events  resulting  in  the

instituted by the Lender, any Releasor,  or any third party.  Anything herein to
the contrary notwithstanding, this Mutual Limited Release will not extend to and
will not affect any claims which may be asserted  pursuant to the Loan Agreement
or all other Loan  Documents  or with  respect to claims  accruing or arising in
respect of acts, omissions or events after the date of this Agreement.

         Anything in this  instrument  to the  contrary  notwithstanding,  it is
expressly understood and agreed that this instrument does not in any way affect,

EqualNet,  Inc.  ("EqualNet")  payable  to  Ciera,  and  that  certain  Security
Agreement  dated as of May 28, 2003, by and between  EqualNet and Ciera,  all of
Ciera's rights under such  instrument and document having been pledged to Lender
as security for the  Obligations,  and which  instruments  and  documents  shall
survive the execution of this Mutual Limited Release.

other  than as  contained  herein,  in the Loan  Agreement,  and the other  Loan
