Corp., a Delaware corporation and a wholly-owned subsidiary of C-Cube 
("MERGER SUB"), and DiviCom, DiviCom will merge with and into Merger Sub (the

wholly-owned subsidiary of C-Cube; and

     B.   Stockholder is the beneficial owner (as defined in Rule 13d-3 under 
the Securities Exchange Act of 1934, as amended (the "EXCHANGE ACT")) of such 
number and class of shares of the outstanding capital stock of DiviCom as is 
indicated on Exhibit A to this Agreement (the "SHARES").

     NOW, THEREFORE, the parties agree as follows:

     1.   AGREEMENT TO RETAIN SHARES.

          1.1  TRANSFER AND ENCUMBRANCE.  Stockholder agrees not to transfer 
(except for transfers among family members for tax and estate planning 
purposes, transfers among corporate affiliates and as may be specifically 
required by court order or by operation of law), sell, exchange, pledge 
(except in connection with a bona fide loan transaction, provided that any 
pledgee agrees not to transfer, sell, exchange, pledge or otherwise dispose 
of or encumber the Shares or any New Shares (as defined in Section 1.2) prior 
to the Expiration Date or otherwise dispose of or encumber the Shares or any 
New Shares, or to make any offer or agreement relating thereto, at any time 
prior to the Expiration Date.  As used herein, the term "Expiration Date" 
shall mean the earlier to occur of (i) such date and time as the Merger shall 
become effective in accordance with the terms and provisions of the 
Reorganization Agreement, and (ii) the date of termination of the 
Reorganization Agreement in accordance with its terms.

          1.2  NEW SHARES.  Stockholder agrees that any shares of capital 
stock of DiviCom that Stockholder purchases or with respect to which 
Stockholder otherwise acquires beneficial ownership after the date of this 
Agreement and prior to the Expiration Date ("NEW SHARES") shall be subject to 
the terms and conditions of this Agreement to the same extent as if they 
constituted Shares.








     2.   AGREEMENT TO VOTE SHARES.  At every meeting of the stockholders of 
DiviCom called with respect to any of the following, and at every adjournment 
and postponement thereof, and on every action or approval by written consent 
of the stockholders of DiviCom with respect to any of the following, 
Stockholder shall vote the Shares and any New Shares (i) in favor of approval 
of the Reorganization Agreement, the Merger and any matter that could 
reasonably be expected to facilitate the Merger, (ii) against any proposal 
for any recapitalization, merger, sale of assets or other business 
combination (other than the Merger and any other matter referred to in clause 
(i) of this Section 2) between DiviCom and any person or entity other than 
C-Cube or any other action or agreement that could result in a material 
breach of any covenant, representation or warranty or any other obligation or 
agreement of DiviCom under the Reorganization Agreement or which could result 
in any of the conditions to DiviCom's obligations under the Reorganization 
Agreement not being fulfilled, and (iii) in favor of amending the Certificate 
of Incorporation of DiviCom pursuant to Section 1.13 of the Reorganization 
Agreement.

     3.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF STOCKHOLDER.  
Stockholder hereby represents, warrants and covenants to C-Cube that 
Stockholder (i) is the beneficial owner of the Shares, which at the date of 
this Agreement and at all times up until the Expiration Date will be free and 
clear of any liens, claims, options, charges or other encumbrances; (ii) does 
not beneficially own any shares of capital stock of DiviCom other than the 
Shares (excluding shares as to which Stockholder currently disclaims 
beneficial ownership in accordance with applicable law); and (iii) has full 
power and authority to make, enter into and carry out the terms of this 
Agreement.

     4.   TERMINATION.  This Agreement shall terminate and shall have no 
further force or effect as of the Expiration Date.

     5.   MISCELLANEOUS.

          5.1  SEVERABILITY.  If any term, provision, covenant or restriction 
of this Agreement is held by a court of competent jurisdiction to be invalid, 
void or unenforceable, then the remainder of the terms, provisions, covenants 
and restrictions of this Agreement shall remain in full force and effect and 
shall in no way be affected, impaired or invalidated.

          5.2  BINDING EFFECT AND ASSIGNMENT.  This Agreement and all of the 
provisions hereof shall be binding upon and inure to the benefit of the 
parties hereto and their respective successors and permitted assigns, but, 
except as otherwise specifically provided herein, neither this Agreement nor 
any of the rights, interests or obligations of the parties hereto may be 
assigned by either of the parties without the prior written consent of the 
other.  This Agreement is intended to bind Stockholder as a stockholder of 
DiviCom only with respect to the specific matters set forth herein.

          5.3  AMENDMENT AND MODIFICATION.  This Agreement may not be 
modified, amended, altered or supplemented except by the execution and

adequate remedy at law for a violation of any of the covenants or agreements 
of Stockholder set forth herein.  Therefore, it is agreed that, in addition 
to any other remedies that may be available to C-Cube upon any such 
violation, C-Cube shall have the right to enforce such covenants and
