(iii) to provide financing for ongoing working capital needs and (iv) to finance
expenses relating to the acquisition and the Bridge Facility.

The summary of terms attached hereto is intended to be indicative of the
principal terms of the Bridge Facility and does not purport to specify all of
the terms, conditions, representations and warranties, covenants and other
provisions that will be contained in the final loan documents for the Bridge
Facility.

Dymas is delivering this commitment letter to you in reliance upon the accuracy
of all information furnished to Dymas by you or on your behalf. You agree that
you will not disclose the contents of the summary of terms attached hereto to
any third party (including, without limitation, any financial institution or

directors of and advisors to (including Mooreland Partners) T-NETIX,
shareholders of T-NETIX, providers of subordinated debt, prospective equity
investors, governmental and regulatory authorities and your advisors and
officers ("Approved Third Parties") on a need-to-know basis. You agree to inform
all such persons who receive information concerning Dymas, this commitment
letter, or the summary of terms that such information is confidential and may
not be disclosed to any other person. Not withstanding the preceding paragraph
however, HIG and T-NETIX shall be allowed to provide any and all information to
the extent required by the SEC in connection with the tender offer.

By executing this commitment letter, you agree to pay the fees, costs and
expenses provided for in the summary of terms attached hereto and to indemnify
Dymas, its directors, officers, employees, agents, auditors, accountants,

action arising from an alleged breach by Dymas of this commitment letter the
only damages that may be sought are only those which are direct and reasonably
foreseeable as the probable result of any breach thereof and any right to
indirect, special or punitive damages or lost anticipated profits is hereby
waived.

This commitment letter and the summary of terms attached hereto supersede all
prior discussions, indications of interest and proposals previously delivered to
you. Unless extended in writing by Dymas, in its discretion, this commitment

conditions specified in the summary of terms attached hereto, it is contemplated
that the proceeds of the facility provided for herein and therein shall be used
