6789722 Canada Inc. (“ExchangeCo”) and NewHeights Software Corporation (the
“Company”) intend to effect a business combination by way of a plan of
arrangement (the “Arrangement”) pursuant to an arrangement agreement (the

the Company and, as an inducement and a condition to Parent entering into the
Arrangement Agreement and for other good and valuable consideration (the receipt
and sufficiency of which are hereby acknowledged by the undersigned), the
undersigned covenants and agrees with Parent as set forth herein. For greater
certainty, the undersigned is executing this agreement solely in his capacity as
a holder of common shares of the Company as described in Section 2(a) below and
not in any other capacity (including, without limitation, as a director or

Agreement, or, subject to the Company’s obligations under the Arrangement
Agreement, from taking, or refraining to take, any action whatsoever as a
director, officer, employee or agent of the Company.

all voting rights in respect of such Common Shares and to transfer or cause to

the undersigned is competent to execute and deliver this agreement and this
agreement is a valid and binding agreement enforceable by Parent against the
undersigned in accordance with its terms, subject to the usual exceptions as to
bankruptcy, insolvency, reorganization, moratorium and other laws relating to or
affecting creditors’ rights generally and the availability of equitable
remedies;

      (d)

the execution and delivery of this agreement and the fulfilment of the terms
hereof by the undersigned does not and will not result in a breach of any
agreement or instrument to which the undersigned is a party or by which the

not constitute a violation of this covenant.
