- 6 -

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

Shares or such other securities, in cash or otherwise; or

 

  (iii) publicly announce an intention to effect any transaction specified in

part, from the lock-up restrictions of any similar voting support agreement
related to the transactions contemplated by the Arrangement Agreement, then the
Securityholder shall be released in the same manner from the restrictions of
this Agreement (i.e., in the case where shares of such individual or entity are
released from lock-up restrictions, the same percentage of shares held by the
Securityholder shall be released from the restrictions of this Agreement on the
same terms).

 

  (d) The Securityholder agrees that, until the Expiry Time, neither the
Securityholder nor any of its Representatives will, directly or indirectly:

submissions of proposals or offers from, or provide information to, any other
person, entity or group (other than Aastra or Mitel) relating to any Acquisition
Proposal or potential Acquisition Proposal, (B) participate in any discussions
or negotiations regarding any Acquisition Proposal, or (C) accept or enter into,
or publicly propose to accept or enter into, any letter of intent, agreement,
arrangement or understanding related to any Acquisition Proposal. Nothing
hereunder shall prevent any shareholder, director or officer of the
Securityholder who is a director or officer of Mitel from doing any act or thing
that such director or officer is properly obligated to do in such capacity,
provided that such act or thing is permitted by and is done in strict compliance
with the terms of the Arrangement Agreement.

 

  (e) The Securityholder hereby agrees to:

 

  (i)

immediately cease and cause to be terminated any and all solicitations,
encouragements, existing discussions and negotiations, if any, with any

delaying or varying such transactions or any aspect thereof.

Securityholder on the date hereof.

 

  (i) The Securityholder agrees that, until the Expiry Time, it will not
(i) exercise any securityholder rights or remedies available at common law or
pursuant to applicable securities legislation; or (ii) take any other action of
any kind, in each case which might reasonably be regarded as likely to reduce
the success of, or delay or interfere with the completion of, the transactions
contemplated by the Arrangement Agreement.

 

  (j) The Securityholder hereby irrevocably consents to:

 

  (i) details of this Agreement being set out in any information circular and
court documents produced by Aastra, Mitel or any of their respective Affiliates
