2.5           Most Favored Nation.
 
(a)           If and whenever, on or after the date hereof and before June 30,
2009 (the “MFN Period”), the Company (i) permits the conversion of any note
payable outstanding as of the date hereof at a conversion price below $.53 per
share, then immediately after such conversion, the Company shall issue to
Roaring Fork additional shares of the common stock such that Roaring Fork shall
receive benefit of the more favorable terms of the subsequent conversion or
issuance(s).  By way of example, if the Company permits the conversion of a note
payable outstanding as of the date hereof at a conversion price of $.50 per
share, then Roaring Fork would receive an additional 117,494 shares of the
common stock (calculated by dividing the unpaid principal, interest and
penalties of the Note, as identified in Section 1 above, in the amount of
$1,038,495 by $.50 (2,076,918) and subtracting from that amount the 1,959,424
shares issued to Roaring Fork pursuant to Section 1 above (2,076,918 - 1,959,424
= 117,494)).
 
(b)           If and whenever, during the MFN Period, the Company permits the
exercise of any warrant outstanding as of the date hereof at an exercise price
below $.40 per share, the Company shall issue to Roaring Fork additional shares
of the common stock such that Roaring Fork shall receive benefit of the more
favorable terms of the subsequent exercise.  By way of example, if the Company
permits the exercise of a warrant outstanding as of the date hereof at an
exercise price of $.30 per share, then Roaring Fork would receive an additional
333,334 shares of the common stock (calculated by dividing the aggregate
exercise price paid with respect to Roaring Fork’s exercise of the Warrant
pursuant to Section 2 above ($400,000) by $.30 (1,333,334) and subtracting from
that amount the 1,000,000 shares issued to Roaring Fork pursuant to Section 2
above (1,333,334 - 1,000,000 = 333,334)).
 
(c)           If, during the MFN Period, the Company in any manner issues or
sells any (i) shares of its common stock for no consideration or any
consideration below $.53 per share, or (ii) any Convertible Securities (as
defined below), other than Options (as defined below) granted or sold in
accordance with any employee equity incentive plan, and the lowest price per
share for which one share of the Company's common stock is issuable upon such
conversion or exchange or exercise thereof is less than $.53 per share, then
such share of common stock shall be deemed to be outstanding and to have been
issued and sold by the Company at the time of the issuance or sale of such
Convertible Securities for such price per share.  For the purposes of this
agreement, the  “lowest price per share for which one share of the Company's
common stock is issuable upon such conversion or exchange or exercise ” shall be
equal to the sum of the lowest amounts of consideration (if any) received or
receivable by the Company with respect to any one share of its common stock upon
the issuance or sale of the Convertible Security and upon the conversion or
exchange or exercise of such Convertible Security.  Notwithstanding the
foregoing, this Section (c) shall only apply, and the issuances to Roaring Fork
described in Sections 2.4(a) and (b) shall only be made, (x) after the first
$200,000 in aggregate gross proceeds received by the Company with respect to
sales of common stock or Convertible Securities, and thereafter, (y) only if the
Company repays, redeems, repurchases, retires or otherwise terminates the notes
payable or warrants described in Sections 2.4(a) and (b), within 180 days of the
issuance of shares of common stock or Convertible Securities described in this
Section 2.4(c).
 

 
 

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

 

For purposes of this Agreement, issuances of any rights, warrants or options to
subscribe for or purchase shares of common stock of the Company (“Options”) and
issuances of any stock or securities (other than Options) directly or indirectly
convertible into or exercisable or exchangeable for shares of common stock of
the Company (“Convertible Securities”).

(d)           Notwithstanding this Section 2.4, no issuance of common stock
pursuant to this Section 2.4 shall be made to Roaring Fork with respect to any
shares of common stock or Convertible Securities issued by the Company in
connection with the settlement of its current litigation pending in Dallas,
Texas, styled KINGDON R. HUGHES VS. GREGORY T. ROYAL, CYNTHIA A. GARR, JAMES T.
MILLER, JR., CHARLES STIDHAM, CNH HOLDINGS COMPANY D/B/A CISTERA NETWORKS AND
XBRIDGE SOFTWARE, INC.; Cause No. DV05-0600-G; G-134th District Court, Dallas
County, Texas.
 
2.6           Acknowledgments.  The Company acknowledges that the provisions of
this Section 2 are material to Roaring Fork’s investment decision to convert the
Note, exercise the Warrant and purchase the additional shares of stock as set
forth in Sections 2.3 above and to terminate the registration obligation in
Section 1.
