Restricted Securities (a "POST-EFFECTIVE AMENDMENT") (subject to the right of
the Company to suspend the use of the Prospectus as described in Section 2.1(d)
hereof); provided, however, that (i) if a supplement to the related Prospectus
is required to permit the Holder (or other Holders not included in the Shelf
Registration Statement upon effectiveness) to deliver the Prospectus to
purchasers of Transfer Restricted Securities, the Company shall not be required
to file more than one (1) such supplement during any thirty (30) day period and
(ii) if a post effective amendment to the Shelf Registration Statement is
required to permit the Holder (or other Holders not included in the Shelf
Registration Statement upon

                                       6
<PAGE>

effectiveness) to deliver the Prospectus to purchasers of Transfer Restricted
Securities, the Company shall not be required to file more than one (1)
post-effective amendment to the Shelf Registration Statement in any ninety (90)
day period. The Company shall use its reasonable best efforts to cause any such
post-effective amendment to become effective under the 1933 Act as promptly as
is practicable; provided, that if a Notice and Questionnaire is delivered to the
Company during a Suspension Period, the Company shall not be obligated to amend
the Shelf Registration Statement or supplement the Prospectus until the
termination of such Suspension Period.

                        (iii) Each Holder as to which the Shelf Registration
Statement is being effected shall furnish promptly to the Company (x) such other
information as the Company may reasonably request for use in connection with the
Shelf Registration Statement or Prospectus or in any application to be filed
with or under state securities laws and (y) all information required to be
disclosed in order to make the information previously furnished to the Company
by such Holder not misleading.

                  c. The Company shall use its reasonable best efforts to keep
the Shelf Registration Statement continuously effective, supplemented and
amended under the 1933 Act in order to permit the Prospectus forming a part
thereof to be usable, subject to Section 2(d) hereof, by all Notice Holders
until there ceases to be any Transfer Restricted Securities outstanding (such
period being called the "SHELF REGISTRATION PERIOD"). The Company will, in order
to fulfill its obligations and this Section 2.1(c): (x) subject to Section
2.1(b)(ii) and 2.1(d), use its reasonable best efforts to prepare and file with
the SEC such amendments and post-effective amendments to the Shelf Registration
Statement as may be necessary to keep the Shelf Registration Statement
continuously effective for the Shelf Registration Period; (y) subject to Section
2.1(b)(ii) and 2.1(d), cause the related Prospectus to be supplemented by any
required supplement, and as so supplemented to be filed pursuant to Rule 424 (or

material respects with the provisions of the 1933 Act with respect to the
disposition of all Transfer Restricted Securities covered by the Shelf
Registration Statement during the Shelf Registration Period.

                  d. The Company may suspend the availability of any Shelf
Registration Statement and the use of any Prospectus (the period during which
the availability of any Shelf Registration Statement and any Prospectus may be
suspended herein referred to as the "SUSPENSION PERIOD"), without incurring any
obligation to pay Special Interest Payments pursuant to Section 2.1(e), for a
period not to exceed: (i) 30 consecutive days at any one time; (ii) 45 days in
the aggregate in any three-month period; or (iii) 90 days in the aggregate
during any 12-month period, in each case only for valid business reasons, to be
determined in good faith by the Company in its reasonable judgment (which shall
not include the avoidance of the Company's obligations hereunder), including,
without limitation, the acquisition or divestiture of assets, pending corporate
developments, events listed in Section 3(c), public filings with the SEC and
similar events; provided, that the Company promptly thereafter complies with the
requirements of Section 3(j) hereof, if applicable, and provided further that,
if a Post-Effective Amendment is required by applicable law to cause a Holder to
be named as a selling securityholder in the Shelf Registration Statement, the
period of time between the filing and the effectiveness of any Post-Effective
Amendment shall be not deemed to be a Suspension Period

                                       7

<PAGE>

hereunder. The first day of any Suspension Period must be at least two (2)
trading days after the last day of any prior Suspension Period.

                  e. If: (i) the Shelf Registration Statement has not been
declared effective by the SEC on or prior to the date that is 180 days following
the completion of the Qualified IPO, or in the case of Warrant Shares, on or
prior to the date that is 180 days following the completion of the first to
occur of a Qualified IPO or a Non-Qualified IPO; or (ii) the Shelf Registration
Statement is filed and declared effective but shall thereafter cease to be
effective (without being succeeded within 3 Business Days by a replacement Shelf
Registration Statement filed and declared effective) or usable (including as a
result of a Suspension Period) for the offer and sale of Transfer Restricted
Securities for a period of time (including any Suspension Period) which exceeds:
(x) 30 consecutive days at any time; (y) 45 days in the aggregate in any three-
month period; or (z) 90 days in the aggregate in any 12-month period (each such
event referred to in clauses (i) and (ii), a "SPECIAL INTEREST TRIGGER"),
provided that any suspension of the Shelf Registration Statement as a result of
the time required by the SEC to declare effective a post- effective amendment to
the Shelf Registration Statement in connection with the Company's obligation to
file such an amendment pursuant to Section 2.1(b)(ii) hereof shall not be
included in the calculation of a Special Interest Trigger; the Company shall pay
to each Notice Holder, as additional Interest (as defined in the Notes) under
any outstanding Notes held by such Notice Holder, during any period in which a
Special Interest Trigger has occurred or is continuing, as partial relief (which
remedy shall not be exclusive of any other remedies available at law or in
equity), in an amount (the "SPECIAL INTEREST PAYMENTS") equal to one-half of one
percent (50 basis points) per annum per US$1,000 principal amount of such
outstanding Notes during which such Special Interest Trigger has occurred and is
continuing, it being understood that all calculations pursuant to this and the
preceding sentence shall be carried out to five decimal places. Following the
cure of all Special Interest Triggers, Special Interest Payments will cease to
accrue with respect to such Special Interest Triggers. All accrued Special
Interest Payments shall be paid by the Company on each Interest Date (as defined
in the Note) to the date of such cure and Special Interest Payments will be
calculated on the basis of a 360-day year consisting of twelve 30-day months.
Notwithstanding anything in the Agreement to the contrary, Special Interest
Payments shall only be payable to Notice Holders.

                  f. Immediately upon the occurrence or the termination of a
Special Interest Trigger, the Company shall give the Notice Holders, so long as
any Notes remain outstanding, notice of such commencement or termination of the
obligation to pay Special Interest Payments with regard to the Notes, and the
amount thereof and of the nature of the default giving rise to such commencement
or the event giving rise to such termination, as the case may be, and prior to
receipt of such notice the Notice Holders shall be entitled to assume that no
such commencement or termination has occurred.

            2.2 Incidental Registration Statement.

                  a. (i) Following a Qualified IPO or a Non-Qualified IPO, if
the Company at any time or from time to time proposes or is required to register
any of its securities under the 1933 Act (other than (x) in a registration on
Form F-4, S-4, F-8, F-80 or S-8 or any successor form to such forms for
compensatory, bonus or other similar plans, dividend reinvestment plans and
stock purchase plans, or (y) at such times as a Shelf Registration

                                       8
<PAGE>

Statement is effective) whether or not pursuant to registration rights granted
to other holders of its securities and whether or not for sale for its own
account, the Company shall deliver prompt written notice (which notice shall be
given (i) in the event that the Company has publicly disclosed such proposed
registration, at least thirty (30) calendar days prior to such proposed
registration and (ii) in the event that the Company has not publicly disclosed
such proposed registration (a "NON-PUBLIC INCIDENTAL REGISTRATION NOTICE"), no
more than ten (10) Business Days prior to the filing of such proposed
registration with the SEC (such period not in excess of ten (10) Business Days,
the "NON-PUBLIC INCIDENTAL REGISTRATION NOTICE PERIOD")) to all Holders of its
intention to undertake such registration, describing in reasonable detail the
proposed registration and distribution (including the anticipated range of the
proposed offering price, the class and number of securities proposed to be
registered and the distribution arrangements) and of such Holders' right to
participate in such registration under this Section 2.2 as hereinafter provided.
If the Holder elects to participate in such proposed registration, the Holder
shall keep the contents of any Non-Public Incidental Registration Notice
confidential prior to the filing of such proposed registration with the SEC and
if the Holder has elected not to participate in such proposed registration, the
Holder shall keep the contents of any Non-Public Incidental Registration Notice
confidential during the Non-Public Incidental Registration Notice Period.
Subject to the other provisions of this Section 2.2(a) and Section 2.2(b), upon
the written request of any Holder made within twenty (20) calendar days, or in
the case of a Non-Public Incidental Registration Notice, within five (5)
Business Days, after the receipt of such written notice (which request shall
specify the amount of Transfer Restricted Securities to be registered and the
intended method of disposition thereof), the Company shall effect the
registration under the 1933 Act of all Transfer Restricted Securities requested
by Holders to be so registered (an "INCIDENTAL REGISTRATION"), to the extent
requisite to permit the disposition (in accordance with the intended methods
thereof as aforesaid) of the Transfer Restricted Securities so to be registered,
by inclusion of such Transfer Restricted Securities in the Incidental
Registration Statement and shall cause such Registration Statement to become and
remain effective with respect to such Transfer Restricted Securities in
accordance with the registration procedures set forth in Section 3. If an
Incidental Registration involves an Underwritten Offering, immediately upon
notification to the Company from the Underwriter of the price at which such
securities are to be sold, the Company shall so advise each participating
Holder. The Holders requesting inclusion in an Incidental Registration may, at
any time prior to the Effective Date of the Incidental Registration Statement
(and for any reason), revoke such request by delivering written notice to the
Company revoking such requested inclusion.

                        (ii) If at any time after giving written notice of its
intention to register any securities and prior to the Effective Date of the
Incidental Registration Statement filed in connection with such registration,
the Company shall determine for any reason not to register or to delay
registration of such securities, the Company may, at its election, give written
notice of such determination to each Holder and, thereupon, (A) in the case of a
determination not to register, the Company shall be relieved of its obligation
to register any Transfer Restricted Securities in connection with such
registration (but not from its obligation to pay the fees and expenses incurred
in connection therewith as set forth in Section 4), without prejudice, however,
to the Company's obligation to effect a registration under Section 2.1, and (B)
in the case of a determination to delay such registration, the Company shall be
permitted to delay the registration of such Transfer Restricted Securities for
the same period as the delay in registering such other securities; provided,
however, that if such delay shall extend beyond 120 days from the date the

                                       9
<PAGE>

Company received a request to include Transfer Restricted Securities in such
Incidental Registration, upon making the determination to proceed with such
registration the Company shall again give all Holders the opportunity to
participate therein and shall follow the notification procedures set forth in
the preceding paragraph. There is no limitation on the number of such Incidental
Registrations pursuant to this Section 2.2 which the Company is obligated to
effect.

                        (iii) The registration rights granted pursuant to the
provisions of this Section 2.2 shall be in addition to the registration rights
granted pursuant to the other provisions of Section 2 hereof.

                  b. If an Incidental Registration involves an Underwritten
Offering (on a firm commitment basis), and the sole or the lead managing
Underwriter, as the case may be, of such Underwritten Offering shall advise the
Company in writing (with a copy to each Holder requesting registration) on or
before the date five days prior to the date then scheduled for such offering
that, in its opinion, the amount of securities (including Transfer Restricted
Securities) requested to be included in such registration exceeds the amount
which can be sold in such offering without materially interfering with the
successful marketing of the securities being offered (such writing to state the
basis of such opinion and the approximate number of such securities which may be
included in such offering without such effect), the Company shall include in
such registration, to the extent of the number which the Company is so advised
may be included in such offering without such effect, (i) in the case of a
registration initiated by the Company, (A) first, the securities that the
Company proposes to register for its own account, (B) second, other securities
of the Company to be registered on behalf of holders of Existing Incidental
Registration Rights in accordance with the terms of the Existing Registration
Rights Agreement, (C) third, the Transfer Restricted Securities requested to be
included in such registration by the Holders, allocated pro rata in proportion
to the number of Transfer Restricted Securities requested to be included in such
registration by each of them, and (D) fourth, other securities of the Company to
be registered on behalf of any other Person, and (ii) in the case of a
registration initiated by any Person other than the Company, (A) first, the
securities of the Company to be registered on behalf of holders of Existing
Demand Registration Rights, (B) second, the Transfer Restricted Securities
requested to be included in such registration by the Holders, allocated pro rata
in proportion to the number of Transfer Restricted Securities requested to be
included in such registration by each of them, (C) third, other securities of
the Company to be registered on behalf of any other Person, and (D) fourth, any
securities that the Company proposes to register for its own account; provided,
however, that in the event any Holder who requests to be included in such
registration is not so included with respect to all of the Transfer Restricted
Securities it has requested to be included, and any other Person, other than the
Company, is included in such registration, the Company shall, at its expense,
prepare and file with the SEC, concurrently with the filing of the registration
statement (the "Applicable Registration Statement") for the underwritten
offering described in this Section 2.2(b), a Shelf Registration Statement with
respect to resales, from time to time, of the Transfer Restricted Securities
that were not included in the Applicable Registration Statement, substantially
in accordance with the procedures for Shelf Registration set forth in Section
2.1 hereof and on terms no less favorable to the Holders than the terms and
conditions for the holders of securities under the Applicable Registration
Statement (other than such terms that specifically relate to differences between
the firm commitment underwritten nature of the Applicable Registration

                                       10
<PAGE>

Statement and the continuous offering nature of the Shelf Registration
Statement), and shall cause such Shelf Registration Statement to become
effective as soon as reasonably practicable.

            3. Registration Procedures.

            In connection with any Registration Statement, the following
provisions shall apply:

                  a. The Company shall: (i) furnish to the Holders, within a
reasonable period of time, but in any event within four (4) Business Days prior
to the filing thereof with the SEC to afford the Holders and their counsel a
reasonable opportunity for review and to participate in the preparation thereof,
a copy of each Registration Statement, and each amendment thereof, and a copy of
each Prospectus, and each amendment or supplement thereto (excluding amendments
caused by the filing of a report under the 1934 Act); and (ii) include
information regarding the Notice Holders and the methods of distribution they
have elected for their Transfer Restricted Securities provided to the Company in
Notice and Questionnaires as necessary to permit such distribution by the
methods specified therein.

                  b. Subject to Section 2.1(d), the Company shall ensure that:
(i) any Registration Statement and any amendment thereto and any Prospectus
forming a part thereof and any amendment or supplement thereto comply as to form
in all material respects with the 1933 Act; (ii) any Registration Statement and
any amendment thereto does not, when it becomes effective, contain an untrue
statement of a material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein not misleading; and
(iii) any Prospectus forming a part of any Registration Statement, and any
amendment or supplement to such Prospectus, does not include an untrue statement
of a material fact or omit to state a material fact necessary in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading; provided that the Company makes no representation with
respect to any Holder Information.

                  c. The Company, as promptly as reasonably practicable (but in
any event within two (2) Business Days), shall notify each Notice Holder:

                        (i) When a Registration Statement or any post-effective
amendment thereto or any Prospectus or any supplement thereto has been filed
with the SEC and when the Registration Statement or any post-effective amendment
thereto has become effective which notice and confirmation can be made at the
election of the Company by making a public announcement thereof by release made
to Reuters Economic Services, Bloomberg Business News or a similar service;

                        (ii) of any request, following effectiveness of the
Registration Statement under the 1933 Act, by the SEC or any other federal or
state governmental authority for amendments or supplements to the Registration
Statement or the Prospectus or for additional information (other than any such
request relating to a review of the Company's 1934 Act filings);

                        (iii) of the issuance by the SEC or any other federal or
state governmental authority of any stop order suspending the effectiveness of
the Registration

                                       11
<PAGE>

Statement or of any order preventing or suspending the use of any Prospectus or
the initiation or threat of any proceedings for that purpose;

                        (iv) of the receipt by the Company of any notification
with respect to the suspension of the qualification or exemption from
qualification of the Transfer Restricted Securities included in any Registration
Statement for sale in any jurisdiction or the initiation or threat of any
proceeding for that purpose;

                        (v) of the occurrence of, but not the nature of or
details concerning, any event or the existence of any condition that requires
the making of any changes in the Registration Statement or the Prospectus or any
document incorporated by reference therein so that, as of such date, the
statements therein are not misleading and the Registration Statement or the
Prospectus or any document incorporated by reference therein, as the case may
be, does not include an untrue statement of a material fact or omit to state a
material fact required to be stated therein or necessary to make the statements
therein (in the case of the Prospectus, in the light of the circumstances under
which they were made) not misleading;

                        (vi) of the Company's determination that a
post-effective amendment to the Registration Statement is necessary (other than
a post-effective amendment pursuant to Section 2.1(b)(ii)); and

                        (vii) of the commencement (including as a result of any
of the events or circumstances described in paragraph (ii) above) and
termination of any Suspension Period.

                  d. The Company shall use its reasonable best efforts to
obtain: (i) the withdrawal of any order suspending the effectiveness of any
Registration Statement and the use of any related Prospectus; and (ii) the
lifting of any suspension of the qualification (or exemption from qualification)
of any of the Transfer Restricted Securities for offer or sale in any
jurisdiction in which they have been qualified for sale, in each case at the
earliest possible time, and shall provide notice to each Notice Holder of the
withdrawal of any such orders or suspensions.

                  e. The Company shall promptly furnish to each Notice Holder,
without charge, at least one copy of any Registration Statement and any
post-effective amendment thereto, excluding all documents incorporated or deemed
to be incorporated therein by reference and all exhibits thereto.

                  f. The Company shall promptly furnish to the Legal Counsel (i)
copies of any correspondence from the SEC or the staff of the SEC to the Company
or its representatives relating to any Registration Statement, (ii) promptly
after the same is prepared and filed with the SEC, one copy of any Registration
Statement and any amendment(s) thereto, including financial statements and
schedules, all documents incorporated therein by reference, if requested by a
Notice Holder, and all exhibits and (iii) upon the effectiveness of any
Registration Statement, one copy of the prospectus included in such Registration
Statement and all amendments and supplements thereto.

                                       12
<PAGE>

                  g. The Company shall, at the Effective Date, promptly provide
each Notice Holder a copy of the Prospectus included in the Registration
Statement and during the Shelf Registration Period or the period of time during
which any Incidental Registration Statement is effective, as applicable,
promptly deliver to each Notice Holder, without charge, as many copies of the
Prospectus (including each preliminary Prospectus) included in any Registration
Statement, and any amendment or supplement thereto, as such person may
reasonably request and except as provided in Sections 2.1(d) and 3(r) hereof;
and the Company hereby consents to the use of the Prospectus and any amendment
or supplement thereto by each of the selling Notice Holders in connection with
the offering and sale of the Transfer Restricted Securities covered by the
Prospectus or any amendment or supplement thereto.

                  h. The Company shall submit to the SEC, within two (2)
Business Days after the Company learns that no review of a particular
Registration Statement will be made by the staff of the SEC or that the staff
has no further comments on a particular Registration Statement, as the case may
be, a request for acceleration of effectiveness of such Registration Statement
to a time and date not later than 48 hours after the submission of such request.

                  i. Prior to any offering of Transfer Restricted Securities
pursuant to any Registration Statement, the Company shall register or qualify or
cooperate with the Notice Holders and their respective counsel in connection
with the registration or qualification (or exemption from such registration or
qualification) of such Transfer Restricted Securities for offer and sale, under
the securities or blue sky laws of such jurisdictions within the United States
as any such Notice Holders reasonably request and shall maintain such
qualification in effect during the Shelf Registration Period or the period of
time during which any Incidental Registration Statement is effective, as
applicable, and do any and all other acts or things necessary or advisable to
enable the offer and sale in such jurisdictions of the Transfer Restricted
Securities covered by such Registration Statement; provided, however, that the
Company will not be required to: (i) qualify generally to do business as a
foreign, corporation or as a dealer in securities in any jurisdiction where it
is not then so qualified or, (ii) take any action which would subject it to
service of process or taxation in excess of a nominal dollar amount in any such
jurisdiction where it is not then so subject.

                  j. The Company shall cooperate with the Notice Holders to
facilitate the timely preparation and delivery of certificates representing
Transfer Restricted Securities sold pursuant to any Registration Statement free
of any restrictive legends that are placed on such certificates in accordance
with the Securities Purchase Agreement, the Notes and the Warrants, as
applicable.

                  k. Subject to the exceptions contained in (i) and (ii) of
Section 3(i) above, the Company shall use its reasonable best efforts to cause
the Transfer Restricted Securities covered by the applicable Registration
Statement to be registered with or approved by such other federal, state and
local governmental agencies or authorities, and self-regulatory organizations in
the United States as may be necessary to enable the Notice Holders to consummate
the disposition of such Transfer Restricted Securities as contemplated by the
Registration Statement; without limitation to the foregoing, the Company shall
provide all such information as may be required by the NASD in connection with
the offering under the Registration Statement of the Transfer Restricted
Securities (including, without limitation, such as may be required by NASD

                                       13
<PAGE>

Rule 2710 or 2720), and shall cooperate with each Notice Holder in connection
with any filings required to be made with the NASD by such Notice Holder in that
regard.

                  1. Upon the occurrence of any event described in Section
3(c)(iv) or 3(c)(v) hereof, the Company shall promptly prepare and file with the
SEC a post-effective amendment to any Registration Statement, or an amendment or
supplement to the related Prospectus, or any document incorporated therein by
reference, or file a document which is incorporated or deemed to be incorporated
by reference in such Registration Statement or Prospectus, as the case may be,
so that, as thereafter delivered to purchasers of the Transfer Restricted
Securities included therein, the Registration Statement and the Prospectus, in
each case as then amended or supplemented, will not include an untrue statement
of a material fact or omit to state any material fact required to be stated
therein or necessary in order to make the statements therein (in the case of the
Prospectus, in the light of the circumstances under which they were made) not
misleading and, in the case of a post-effective amendment, use its reasonable
best efforts to cause it to become effective as promptly as practicable;
provided that the Company's obligations under this paragraph (1) shall be
suspended if the Company has suspended the use of the Prospectus in accordance
with Section 2.1(d) hereof and given notice of such suspension to Notice
Holders, it being understood that the Company's obligations under this Section
3(1) shall be automatically reinstated at the end of such Suspension Period.

                  m. The Company shall provide, prior to the effective date of
any Registration Statement hereunder, a CUSIP number for the Transfer Restricted
Securities registered under such Registration Statement.

                  n. The Company shall use its reasonable best efforts to comply
with all applicable rules and regulations of the SEC and shall make generally
available to its security holders an earnings statement satisfying the
provisions of Section 1l(a) of the 1933 Act and Rule 158 promulgated by the SEC
thereunder (or any similar rule promulgated under the 1933 Act) for a 12-month
period commencing on the first day of the first fiscal quarter of the Company
commencing after the effective date of any Registration Statement or each
post-effective amendment to any Registration Statement.

                  o. The Company shall cause all Common Shares issuable upon
conversion of the Notes or upon exercise of Warrants to be reserved for listing
on each securities exchange or quotation system on which the Common Shares are
then listed no later than the date the applicable Registration Statement is
declared effective and, shall cause all Common Shares to be so listed when
issued, and, in connection therewith, to make such filings as may be required
under the 1934 Act and to have such filings declared effective as and when
required thereunder.

                  p. The Company may require each Notice Holder of Transfer
Restricted Securities to be sold pursuant to any Registration Statement to
furnish to the Company such information regarding the Notice Holder and the
distribution of such Transfer Restricted Securities sought by the Notice and
Questionnaire and such additional information as may, from time to time, be
required by the 1933 Act and/or the SEC or any other federal or state
governmental authority, and the obligations of the Company to any Notice Holder
under this Agreement shall be expressly conditioned on the compliance of such
Notice Holder with such request.

                                       14
<PAGE>

                  q. If reasonably requested in writing in connection with any
disposition of Transfer Restricted Securities pursuant to a Registration
Statement, make reasonably available for inspection during normal business hours
by a representative for the Notice Holders of such Transfer Restricted
Securities and any broker-dealers, attorneys and accountants retained by such
Notice Holders, all relevant financial and other records, pertinent corporate
documents and properties of the Company and its subsidiaries, and cause the
appropriate executive officers, directors and designated employees of the
Company and its subsidiaries to make reasonably available for inspection during
normal business hours all relevant information reasonably requested by such
representative for the Notice Holders or any such broker-dealers, attorneys or
accountants in connection with such disposition, in each case as is customary
for similar "due diligence" examinations; provided, however, that any
information that is designated by the Company, in good faith, as confidential at
the time of delivery of such information shall be kept confidential by such
Persons, unless disclosure thereof is made in connection with a court,
administrative or regulatory proceeding or required by law, or such information
has become available to the public generally through the Company or through a
third party without an accompanying obligation of confidentiality.

                  r. Each Notice Holder agrees that, upon receipt of notice of
the happening of an event described in Sections 3(c)(ii) through and including
3(c)(vi), it shall forthwith discontinue (and shall cause its agents and
representatives to discontinue) disposition of Transfer Restricted Securities
and will not resume disposition of Transfer Restricted Securities until such
Holder has received copies of an amended or supplemented Prospectus contemplated
by Section 3(1) hereof, or until such Notice Holder is advised in writing by the
Company that the use of the Prospectus may be resumed or that the relevant
Suspension Period has been terminated, as the case may be, provided that the
foregoing shall not prevent the sale, transfer or other disposition of Transfer
Restricted Securities by a Holder in a transaction which is exempt from, or not
subject to, the registration requirements of the 1933 Act, so long as such
Holder does not and is not required to deliver the applicable Prospectus or
Registration Statement in connection with such sale, transfer or other
disposition, as the case may be; and provided, further, that the provisions of
this Section 3(r) shall not prevent the occurrence of a Special Interest Trigger
or otherwise limit the obligation of the Company to pay Special Interest
Payments.

                  s. Each Notice Holder shall promptly notify the Company of any
inaccuracies or changes in the information requiring an amendment to the
applicable Registration Statement or Prospectus provided in such Notice Holder's
Notice and Questionnaire that may occur subsequent to the date thereof at any
time while the Registration Statement remains effective.

                  t. The Company shall use its reasonable best efforts to take
all other steps necessary to effect the registration of the Notes covered by the
Registration Statement contemplated hereby.

            4. Registration Expenses.

            The Company shall bear all fees and expenses incurred in connection
with the performance of its obligations under Sections 2 and 3 hereof and shall
reimburse the Holders for

                                       15
<PAGE>

the reasonable fees and disbursements of the Legal Counsel in an amount not to
exceed US$25,000 per registration. Such fees and expenses shall include, without
limitation: (i) all registration and filing fees and expenses (including filings
made with the NASD); (ii) all fees and expenses of compliance with federal
securities and state Blue Sky or securities laws; (iii) all expenses of printing
(including printing of Prospectuses and certificates for the Common Shares to be
issued upon conversion of the Notes and the Warrants) and the Company's expenses
for messenger and delivery services and telephone; (iv) all fees and
disbursements of counsel to the Company; (v) all application and filing fees in
connection with listing (or authorizing for quotation) the Common Shares on a
national securities exchange or automated quotation system pursuant to the
requirements hereof; and (vi) all fees and disbursements of independent
certified public accountants of the Company. The Company shall bear its internal
expenses (including, without limitation, all salaries and expenses of their
officers and employees performing legal, accounting or other duties), the
expenses of any annual audit and the fees and expenses of any Person, including
special experts, retained by the Company. Notwithstanding the provisions of this
Section 4, each Holder shall bear the expense of any broker's commission, agency
fee and underwriter's discount or commission, if any, relating to the sale or
disposition of such Holder's Transfer Restricted Securities pursuant to a
Registration Statement.

            5. Holdback Arrangements.

            The Company and each Holder of Transfer Restricted Securities
agrees, if timely requested in writing by the sole or lead managing underwriter
in a Qualified IPO or a Non-Qualified IPO, not to (i) sell, offer to sell,
contract or agree to sell, hypothecate, hedge, pledge, grant any option to
purchase or otherwise dispose of or agree to dispose of, directly or indirectly,
any Transfer Restricted Securities or warrants or other rights to purchase
Transfer Restricted Securities, or file or cause to be declared effective a
registration statement under the 1933 Act relating to the offer and sale of any
shares of Transfer Restricted Securities, or (ii) enter into any swap or other
arrangement that transfers to another, in whole or in part, any of the economic
consequences of ownership of Transfer Restricted Securities, or warrants or
other rights to purchase Transfer Restricted Securities, whether any such
transaction is to be settled by delivery of such securities, in cash or
otherwise (the agreements contained in clauses (i) and (ii) of this Section 5,
collectively, the "LOCK-UP AGREEMENT"), during the time period reasonably
requested by the sole or lead managing underwriter not to exceed 180 days,
beginning on the later of (x) the effective date of the Registration Statement
for such Qualified IPO or Non-Qualified IPO, respectively, and (y) in the case
of a Qualified IPO or Non-Qualified IPO involving a Canadian prospectus, the
date upon which a final receipt is obtained from the applicable Canadian
regulatory authority or Canadian regulatory authorities, as applicable, for such
prospectus (except as part of such underwritten offering or pursuant to
registrations on Forms S-4, F-4, S-8, F-8 or F-80) without the prior written
consent of the sole or lead managing underwriter (the "PUBLIC OFFERING LOCK-UP
PERIOD"); provided, however, that if (i) during the period that begins on the
date that is fifteen (15) calendar days plus three (3) Business Days before the
last day of the Public Offering Lock-Up Period and ends on the last day of the
Public Offering Lock-Up Period, the Company issues an earnings release or
material news or a material event relating to the Company occurs, or (ii) prior
to the expiration of the Public Offering Lock-Up Period, the Company announces
that it will release earnings results during the sixteen (16) day period
beginning on the last day of the Public Offering Lock-Up Period, the
restrictions imposed shall continue to apply until the expiration of the date
that is fifteen (15) calendar days plus three (3)

                                       16
<PAGE>

Business Days after the date on which the issuance of the earnings release or
the material news or material event occurs. Notwithstanding the foregoing, (i)
the Holders of Transfer Restricted Securities shall not be obligated to enter
into the Lock-Up Agreement unless (A) all officers and directors of the Company
and all Persons holding at least 2.5% of the Company's voting securities enter
into substantially similar agreements, with the agreement of the Holders
(including the proviso set forth in the immediately preceding sentence) being on
no more onerous terms than any other agreements entered into by any other
Person, and (B) the Lock-Up Agreement is explicitly conditioned on the Holder
receiving the benefits of any release or modification of such agreement for any
other Person subject to such an agreement or similar agreement, and (ii) the
Lock-Up Agreement shall immediately terminate in respect of the Notes and the
Conversion Shares upon the occurrence of an Event of Default (as defined in the
Notes).

            6. Indemnification and Contribution.

                  a. The Company shall indemnify and hold harmless each Holder
of Transfer Restricted Securities covered by any Registration Statement, its
directors, officers, partners, members and employees and each Person, if any,
who controls any such Holder within the meaning of either the 1933 Act or the
1934 Act (collectively referred to for purposes of this Section 6 as a "HOLDER")
against any losses, claims, damages or liabilities, joint or several, or actions
in respect thereof, to which any of them may become subject, under the 1933 Act
or otherwise, insofar as such losses, claims, damages, liabilities or actions
arise out of or are based upon an untrue statement or alleged untrue statement
of a material fact contained in the Registration Statement, or in any
Prospectus, or any amendment thereof or supplement thereto, or arise out of or
are based upon the omission or alleged omission to state therein a material fact
necessary to make the statements therein (in the case of any Prospectus, in the
light of the circumstances under which they were made) not misleading, and will
reimburse each such party for any legal or other expenses reasonably incurred by
such party in connection with investigating or defending any such action or
claim as such expenses are incurred; provided, however, that: (i) the Company
shall not be liable in any such case to the extent that any such loss, claim,
damage or liability arises out of or is based upon Holder Information; (ii) with
respect to any untrue statement or omission of material fact made in any
Registration Statement, or in any Prospectus, the indemnity agreement contained
in this Section 6(a) shall not inure to the benefit of a Holder from whom the
Person asserting any such loss, claim, damage or liability purchased the
securities concerned, to the extent that any such loss, claim, damage or
liability of such Holder occurs under the circumstance where it shall have been
established that: (w) the Company had previously furnished copies of the
Prospectus, and any amendments and supplements thereto, to such Holder; (x)
delivery of the Prospectus, and any amendment or supplements thereto, was
required by the 1933 Act to be made to such Person; (y) the untrue statement or
omission of a material fact contained in the Prospectus was corrected in
amendments or supplements thereto; and (z) there was not received by such
Person, at or prior to the written confirmation of the sale of such securities
to such Person, a copy of such amendments or supplements to the Prospectus; and
(iii) the indemnification provisions of this Section shall not apply to amounts
paid in settlement of any loss, claim, damage or liability if such settlement is
effected without the prior written consent of the Company, which consent shall
not be unreasonably withheld or delayed. This indemnity agreement will be in
addition to any liability that the Company may otherwise have. This indemnity
agreement will not apply to any loss, damage, expense, liability or claim
arising from an offer or sale, occurring during a Suspension

                                       17
<PAGE>

Period, of Transfer Restricted Securities by a Notice Holder who has previously
received notice from the Company of the commencement of the Suspension Period
pursuant to Section 3(c)(vii).

                  b. Each Holder, severally and not jointly, agrees to indemnify
and hold harmless the Company, each of its directors and officers and each
Person, if any, who controls the Company within the meaning of either the 1933
Act or the 1934 Act, to the same extent as the foregoing indemnity from the
Company to the Holders and shall reimburse each such indemnified party, as
incurred, for any legal or other expenses reasonably incurred by them in
connection with investigating or defending any loss, claim, damage, liability or
action, but only with reference to Holder Information supplied by such Holder.
In no event shall any Holder be liable or responsible for any amount in excess
of the net proceeds to such Holder as a result of the sale of Transfer
Restricted Securities pursuant to such Registration Statement by reason of such
untrue or alleged untrue statement or omission or alleged omission. This
indemnity agreement will be in addition to any liability that such Holder may
otherwise have.

                  c. Promptly after receipt by an indemnified party under this
Section 6 of notice of any claim or the commencement of any action or proceeding
(including any governmental investigation), such indemnified party will, if a
claim for indemnification in respect thereof is to be made against the
indemnifying party under Section 6(a) or 6(b) hereof, notify the indemnifying
party in writing of the commencement thereof; but the omission to so notify the
indemnifying party will not relieve it from any liability which it may have to
any indemnified party to the extent it is not materially prejudiced as a result
thereof. In case any such action or proceeding is brought against any
indemnified party, and it notifies the indemnifying party of the commencement
thereof, the indemnifying party will be entitled to participate therein (jointly
with any other indemnifying party similarly notified), and to the extent that it
may elect, by written notice, delivered to such indemnified party promptly after
receiving the aforesaid notice from such indemnified party, to assume the
defense thereof, with counsel reasonably satisfactory to such indemnified party;
provided, however, that if the defendants (including any impleaded parties) in
any such action include both the indemnified party and the indemnifying party
and the indemnified party shall have reasonably concluded that there may be
legal defenses available to it and/or other indemnified parties which are
different from or additional to those available to the indemnifying party, the
indemnified party or parties shall have the right to select separate counsel to
defend such action on behalf of such indemnified party or parties. Upon receipt
of notice from the indemnifying party to such indemnified party of its election
to so appoint counsel to defend such action and approval by the indemnified
party of such counsel, the indemnifying party will not be liable to such
indemnified party under this Section 6 for any legal or other expenses
subsequently incurred by such indemnified party in connection with the defense
thereof unless: (i) the indemnified party shall have employed separate counsel
in accordance with the proviso to the preceding sentence (it being understood,
however, that the indemnifying party shall not be liable for the expense of more
than one separate counsel (in addition to any local counsel), approved by the
Holders in the case of paragraph (a) of this Section 6, representing the
indemnified parties under such paragraph (a) who are parties to such action);
(ii) the indemnifying party shall not have employed counsel reasonably
satisfactory to the indemnified party to represent the indemnified party within
a reasonable time after notice or commencement of the action; (iii) the
indemnifying party has authorized the employment of counsel for the indemnified
party at the expense of the indemnifying party; or (iv) the use of counsel
chosen by the indemnifying party to represent the

                                       18
<PAGE>

indemnified party would present such counsel with a conflict of interest. An
indemnifying party will not, without the prior written consent of the
indemnified parties, settle or compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit or
proceeding in respect of which indemnification or contribution may be sought
hereunder (whether or not the indemnified parties are actual or potential
parties to such claim or action) unless such settlement, compromise or consent
includes an unconditional release of each indemnified party from all liability
arising out of such claim, action, suit or proceeding. Subject to the provisions
of the immediately following sentence, no indemnifying party shall be liable for
any settlement, compromise or the consent to the entry of judgment in connection
with any such action effected without its written consent, but if settled with
its written consent or if there be a final judgment for the plaintiff in any
such action other than a judgment entered with the consent of such indemnified
party, the indemnifying party shall indemnify and hold harmless any indemnified
party from and against any loss or liability by reason of such settlement or
judgment. If at any time an indemnified party shall have requested that an
indemnifying party reimburse the indemnified party for reasonable fees and
expenses of counsel as contemplated by this Section 6(c) and to which it would
be entitled under Section 6(a) or 6(b) hereof, the indemnifying party agrees
that it shall be liable for any settlement of any proceeding effected without
its written consent if: (x) such settlement is entered into more than 60 days
after receipt by such indemnifying party of such request for reimbursement, (y)
such indemnifying party shall have received notice of the terms of such
settlement at least 45 days prior to such settlement being entered into and (z)
such indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement. Each
indemnified party shall furnish such information regarding itself or the claim
in question as an indemnifying party may reasonably request in writing and as
shall be reasonably required in connection with the defense of such claim and
litigation arising therefrom.

                  d. In the event that the indemnity provided in paragraph (a)
or (b) of this Section 6 is unavailable to or insufficient to hold harmless an
indemnified party for any reason, each indemnifying party shall contribute to
the aggregate losses, claims, damages and liabilities (including legal or other
expenses reasonably incurred in connection with investigating or defending same)
(collectively, "LOSSES") to which the indemnified party may be subject to the
fullest extent permitted by law; provided, however, that in no case shall an
indemnifying party that is a Holder be responsible for any amount in excess of
the total price at which the Transfer Restricted Securities are sold by such
Holder to a purchaser. If the allocation provided by the immediately preceding
sentence is unavailable for any reason, the Company and such Holder shall
contribute in such proportion as is appropriate to reflect not only the relative
benefits but also the relative fault of the Company on the one hand and of such
Holder on the other in connection with the statements or omissions which
resulted in such Losses, as well as any other relevant equitable considerations.
The relative benefits received by the Company on the one hand and such Holder on
the other shall be deemed to be in the same respective proportions as the total
net proceeds from the sale of the Notes (before deducting expenses) received by
or on behalf of the Company, on the one hand, and the total net proceeds
received by such Holder with respect to its sale of Transfer Restricted
Securities under the Registration Statement, on the other hand, bear to the
total net proceeds from the sale of the Notes. Relative fault shall be
determined by reference to, among other things, whether any untrue or any
alleged untrue statement of a material fact or the omission or alleged omission
to state a material fact relates to information provided by the Company on the
one hand or relates to Holder Information supplied by such

                                       19
<PAGE>

Holder, on the other, the intent of the parties and their relative knowledge,
information and opportunity to correct or prevent such untrue statement or
omission. The parties agree that it would not be just and equitable if
contribution pursuant to this paragraph (d) were determined by pro rata
allocation or any other method of allocation that does not take account of the
equitable considerations referred to above. Notwithstanding the provisions of
this paragraph (d), no Person guilty of fraudulent misrepresentation (within the
meaning of Section (1)(f) of the 1933 Act) shall be entitled to contribution
from any Person with respect to claims arising directly out of or relating to
such fraudulent misrepresentation who was not guilty of such fraudulent
misrepresentation. For purposes of this Section 6(d), each Person who controls
such Holder within the meaning of either the 1933 Act or the 1934 Act shall have
the same rights to contribution as such Holder, and each Person who controls the
Company within the meaning of either the 1933 Act or the 1934 Act shall have the
same rights to contribution as the Company, subject in each case to the
applicable terms and conditions of this paragraph (d).

                  e. The remedies provided for in this Section 6 are not
exclusive and shall not limit any rights or remedies which may otherwise be
available to any indemnified party at law or in equity.

                  f. The provisions of this Section 6 will remain in full force
and effect regardless of (i) the termination of this Agreement, (ii) any
investigation made by or on behalf of any Holder, any underwriter or the Company
or any of the officers, directors or controlling Persons referred to in Section
6 hereof and (iii) the sale by a Holder of Transfer Restricted Securities
covered by a Registration Statement.

                  g. Rules 144 and 144A. The Company covenants that it shall use
its reasonable best efforts to file the reports required to be filed by it under
the 1934 Act in a timely manner so long as the Transfer Restricted Securities
remain outstanding. If at any time the Company is not required to file such
reports, it will, upon request of any Holder or beneficial owner of Transfer
Restricted Securities, make available such information necessary to permit sales
pursuant to Rule 144A. The Company further covenants that, for as long as any
Transfer Restricted Securities remain outstanding, it will take such further
action as any Holder of Transfer Restricted Securities may reasonably request,
all to the extent required from time to time to enable such Holder to sell
Transfer Restricted Securities without registration under the 1933 Act within
the limitation of the exemptions provided by Rule 144 and Rule 144A. Upon the
written request of any Holder of Transfer Restricted Securities, the Company
shall deliver to such Holder a written statement as to whether it has complied
with such requirements.

            7. Miscellaneous.

                  a. No Inconsistent Agreements. The Company has not, as of the
date hereof, entered into nor shall it, on or after the date hereof, enter into,
any agreement with respect to its securities that is inconsistent with the
rights granted to the Holders herein or otherwise conflicts with the provisions
hereof (except for such conflicting provisions existing as of the date hereof in
respect of which the Company has obtained valid and binding waivers of such
provisions eliminating any such inconsistencies or conflicts thereunder). In
addition, the Company shall not grant to any of its securityholders (other than
the Holders of Transfer Restricted Securities in such capacity) the right to
include any of such securityholder's securities

                                       20
<PAGE>

in the Registration Statement provided for in this Agreement other than the
Transfer Restricted Securities.

                  b. Amendments and Waivers. The provisions of this Agreement,
including the provisions of this sentence, may not be amended, qualified,
modified or supplemented, and waivers or consents to departures from the
provisions hereof may not be given, unless the Company consents in writing and
the Company has obtained the written consent of the Majority Holders; provided
that with respect to any matter that directly or indirectly affects the rights
of the Buyers hereunder, the Company shall obtain the written consent of the
Buyers against which such amendment, qualification, supplement, waiver or
consent is to be effective. Notwithstanding the foregoing (except the foregoing
proviso), a waiver or consent to departure from the provisions hereof with
respect to a matter that relates exclusively to the rights of Holders whose
Transfer Restricted Securities are being sold pursuant to a Registration
Statement and that does not directly or indirectly affect the rights of other
Holders may be given by the Majority Holders.

                  c. Notices. All notices and other communications provided for
or permitted hereunder shall be made in writing by hand-delivery, first-class

            All such notices and communications shall be deemed to have been
duly given when received, if delivered by hand or air courier, and when sent, if
sent by first-class mail or telecopier.

            The Buyers or the Company by notice to the other may designate
additional or different addresses for subsequent notices or communications.

            The Company hereby irrevocably appoints Mitel Networks, Inc. at 205
Van Buren Street, Herndon, Virginia 20170, Telephone: (613) 592-2122, Facsimile:
(613) 592-7802, Attention: Greg Hiscock, Corporate Counsel, as its agent for the
receipt of service of process in connection with any action pursuant to this
Agreement in the United States. The Company agrees that any document may be
effectively served on it in connection with any action, suit or proceeding in
the United States by service on its agents.

            Any document shall be deemed to have been duly served if marked for
the attention of the agent at its address (as set out above) or such other
address in the United States as may be notified to the party wishing to serve
the document and delivered in accordance with the notice provisions set forth in
this Section 7(c).

            If the Company's agent at any time ceases for any reason to act as
such, the Company shall appoint a replacement agent having an address for
service in the United States and shall notify each Buyer in writing of the name
and address of the replacement agent. Failing such appointment and notification,
each Buyer shall be entitled by notice to the Company to appoint a replacement
agent to act on the Company's behalf. The provisions of this Section 7(c)
applying to service on an agent apply equally to service on a replacement agent.

                  d. Successors and Assigns. This Agreement shall inure to the
benefit of and be binding upon the successors and assigns of each of the
parties, including, without the need for an express assignment or any consent by
the Company thereto, subsequent Holders. The Company hereby shall extend the
benefits of this Agreement to any Holder and any such Holder may specifically
enforce the provisions of this Agreement as if an original party hereto. Any
heir, successor or assign of a Holder wishing to avail itself of the benefits of
this Agreement agrees to acquire and hold the Transfer Restricted Securities
subject to all of the terms hereof. In the event that any other Person shall
succeed to the Company under the Notes, then such successor shall enter into an
agreement, in form and substance reasonably satisfactory to the Majority
Holders, whereby such successor shall assume all of the Company's obligations
under this Agreement.

<PAGE>

                  e. Counterparts. This Agreement may be executed in any number
of counterparts and by the parties hereto in separate counterparts, each of
which when so executed shall be deemed to be an original and all of which taken
together shall constitute one and the same agreement; provided that a facsimile
signature shall be considered due execution and shall be binding upon the
signatory thereto with the same force and effect as if the signature were an
original, not a facsimile signature.

                  f. Headings. The headings in this Agreement are for
convenience of reference only and shall not limit or otherwise affect the
meaning hereof.

                  g. Governing Law. All questions concerning the construction,
validity, enforcement and interpretation of this Agreement shall be governed by
the internal laws of the State of New York, without giving effect to any choice
of law or conflict of law provision or rule (whether of the State of New York or
any other jurisdictions) that would cause the application of the laws of any
jurisdictions other than the State of New York. Each party hereby irrevocably
submits to the exclusive jurisdiction of the state and federal courts sitting in
The City of New York, Borough of Manhattan, for the adjudication of any dispute
hereunder or in connection herewith or with any transaction contemplated hereby
or discussed herein, and hereby irrevocably waives, and agrees not to assert in
any suit, action or proceeding, any claim that it is not personally subject to
the jurisdiction of any such court, that such suit, action or proceeding is
brought in an inconvenient forum or that the venue of such suit, action or
proceeding is improper. Each party hereby irrevocably waives personal service of
process and consents to process being served in any such suit, action or
proceeding by mailing a copy thereof to such party at the address for such
notices to it under this Agreement and agrees that such service shall constitute
good and sufficient service of process and notice thereof. Nothing contained
herein shall be deemed to limit in any way any right to serve process in any
manner permitted by law. EACH PARTY HEREBY IRREVOCABLY WAIVES ANY RIGHT IT MAY
HAVE, AND AGREES NOT TO REQUEST, A JURY TRIAL FOR THE ADJUDICATION OF ANY
DISPUTE HEREUNDER OR IN CONNECTION HEREWITH OR ARISING OUT OF THIS AGREEMENT OR
ANY TRANSACTION CONTEMPLATED HEREBY.

                  h. Severability. In the event that any of the provisions
contained herein, or the application thereof in any circumstances, is held
invalid, illegal or unenforceable in any respect for any reason, the validity,
legality and enforceability of any such provision in every other respect and of
the remaining provisions hereof shall not be in any way impaired or affected
thereby, it being intended that all of the rights and privileges of the parties
shall be enforceable to the fullest extent permitted by law.

                  i. Notes Held by the Company, Etc. Whenever the consent or
approval of Holders of a specified percentage of principal amount of Notes or
the Common Shares issuable upon conversion thereof is required hereunder, Notes
or the Common Shares issued upon conversion thereof held by the Company or its
Affiliates (other than subsequent Holders of Notes or the Common Shares issued
upon conversion thereof if such subsequent Holders are deemed to be Affiliates
solely by reason of their holdings of such Notes) shall not be counted in
determining whether such consent or approval was given by the Holders of such
required percentage.

                  j. Termination. This Agreement and the obligations of the
parties hereunder shall terminate upon the later of (i) the end of the Shelf
Registration Period, and (ii) the end of the period of time during which the
Incidental Registration Statement is effective, except for any liabilities or
obligations under Section 2.1(e), 4 or 6.

                  k. Independent Nature of Buyers' Obligations and Rights. The
obligations of each Buyer in connection with the provisions of this Agreement or
the Securities Purchase Agreement are several and not joint with the obligations
of any other Buyer, and no Buyer shall be responsible in any way for the
performance of the obligations of any other Buyer under this Agreement or the
Securities Purchase Agreement. Nothing contained herein or therein, and no
action taken by any Buyer pursuant hereto or thereto, shall be deemed to
constitute the Buyers as a partnership, an association, a joint venture or any
other kind of entity, or create a presumption that the Buyers are in any way
acting in concert or as a group with respect to such obligations or the
transactions contemplated by this Agreement. Each Buyer confirms that it has
independently participated in the negotiation of the transaction contemplated
hereby with the advice of its own counsel and advisors. Each Buyer shall be
entitled to independently protect and enforce its rights, including, without
limitation, the rights arising out of this Agreement, and it shall not be
necessary for any other Buyer to be joined as an additional party in any
proceeding for such purpose.

                  l. Currency. Unless otherwise indicated, all dollar amounts
referred to in this Agreement are in United States Dollars.

                                    AGREEMENT

AGREEMENT made this first day of October, 2004 ("Effective Date") between MITEL
NETWORKS SOLUTIONS, INC. (hereinafter referred to as the "Company") and the
INTERNATIONAL BROTHERHOOD OF ELECTRICAL WORKERS, AFLCIO (hereinafter referred to
as the "Union"). All references herein to gender shall be construed as being
equally applicable without any reservation to both males and females.

                                   RECOGNITION

Section 1. The Company recognizes the International Brotherhood of Electrical
Workers as the exclusive collective bargaining agent for all technicians
employed by Mitel Networks Solutions, Inc. who are engaged in the installation
and service of telecommunications systems within the geographic United States.
This Agreement does not cover employees covered by another collective-bargaining
agreement and specifically excludes all (a) clerical employees, (b) professional
employees, (c) marketing representatives, (d) guards, (e) supervisors as defined
in the National Labor Relations Act, and (f) all other employees.

                                  WORK COVERED

Section 2. This Agreement covers all installation, inspection and service work
in connection with telephone systems, sound and intercommunication systems,
including such work in connection with other brands as may be assigned to
employees represented by the Union, but does not cover the installation of
building power supply outlets by means of which external electrical power is
supplied to the aforesaid products. Nothing herein contained shall limit the
right of the Company to use its employees for installation and service work on
electronic equipment, provided that such other work shall not conflict with the
established jurisdictional rights and privileges of the other members of the
Union.

Supervisors and other employees outside the bargaining unit shall not be
assigned or permitted to perform bargaining unit work except to (a) instruct
bargaining unit member(s), or (b) perform experimental work. Supervisors and
trainers may assist bargaining unit member(s) in their duties as long as such
assignment does not circumvent the terms of this Agreement.

A stockperson shall be employed whenever there are twenty (20) or more hours of
stock handling work to be performed weekly in a Geographic Location. Stock
handling includes receipt, storage, shipping and handling of inventory,
including the keeping of such inventory records as the Regional Director may
require of the stockperson. In any cases where there are twenty (20) or more,
but less than forty (40) hours of work per week of stock handling, the
stockperson may be assigned by the Regional Director to other than technical
work sufficient to complete a forty (40) hour work week; provided, however, that
no stockperson shall be required to perform complete janitorial service for a
Geographical Location.

                                MANAGEMENT RIGHTS

Section 3. The rights of management in the operation of its business are limited
only by the provisions of this Agreement as specifically stated herein. Without
limiting the generality of the foregoing, the Company reserves the right to
determine the number of employees within each job classification as well as the
right to assign work based on business needs.

                                   WAGE RATES

Section 4. The minimum basic hourly wage rates of all employees covered by this
Agreement and the dates on which they are effective are set forth below:

  10/2/04

Senior Field Service Engineer
Field Service Engineer

<PAGE>

Master Telephone Tech
Telephone Technician-4
Telephone Technician-3
Telephone Technician-2
Telephone Technician-1

If the Company on or before December 31, 2006 does not file with the U.S.
Securities and Exchange Commission to provide its securities in an Initial
Public Offering, then employees will receive a four percent (4%) wage increase
effective as of October 1, 2006.

The Company will provide a One Dollar ($1.00) per hour additional pay to FSEs
and Senior FSEs who have obtained Microsoft Certified Service Engineer (MCSE)
certification as of the Effective Date. For those FSEs and Senior FSEs who have
not received MCSE certification as of the Effective Date, the Company will
provide One Dollar ($1.00) per hour additional pay for obtaining Cisco Certified
Network Associate (CCNA) certification. The number and locations of these
candidates will be at the discretion of the Company based on market and business
needs.

On new construction jobs where telephone systems are to be installed and a Local
Union of the IBEW has an agreement or agreements containing a higher rate of pay
than the rates in this Agreement for such telephone installation work, and it is
established that competitors of the Company are performing such work and are
also required to pay this scale of wages, the higher rate of pay less fringe
benefit value as established for the journeymen inside wiremen shall be paid on
new construction jobs whenever telephone systems and their associated equipment
and wiring are to be installed. In locations where no such higher rates exist,
the Company shall pay not less than the rates specified in this Agreement. In
all cases this national agreement will supercede any local agreement.

An addition to an existing structure shall be considered as new construction for
this purpose.

Redecoration, refurbishing, and rehabilitation do not constitute new
construction except in that instance where there now exists a practice which was
established by mutual agreement prior to the date of this Agreement. Work shall
be considered as performed on a new construction job under the foregoing until
new construction work is completed and Building Trades workers are no longer
performing work at the construction site.

While the foregoing provision as to the scale of wages applies to cabling and
other installation work, it does not apply to the work of delivery, uncrating,
set-up, programming, adjusting, and servicing of the equipment, which work shall
be performed by the Company's employees under the terms of this Agreement.

When rate of pay is involved in other benefits under this Agreement, the rate
shall be the employee's existing rate of pay under this Agreement.

With respect to telephone systems work to be performed at a location within the
top sixteen (16) Metropolitan Statistical Areas (MSAs) as determined by the U.S.
Department of Commerce, the Company agrees that it may subcontract such work
only where such action will not cause a loss of work opportunities within that
MSA to a technician covered by this Agreement. In addition, the Company may not
subcontract work inside an MSA in the top sixteen (16) MSAs in excess of forty
(40) hours per week for a period of six (6) months. Should such subcontract work
be sustained for a six (6) month period and should it be reasonably believed to
be sustainable over the near term, the Company will hire an employee for each
forty (40) hours of work that the Company anticipates will continue. Upon
request of a Local Union, the Company will provide documentation of how many
hours of work per week have been subcontracted within the relevant MSA during
the prior six (6) month period.

With respect to telephone systems work to be performed at a location outside of
the top sixteen (16) MSAs, the Company agrees that it may subcontract such work
only where such action will not cause a loss of work opportunities within fifty
(50) miles of the domicile of a technician covered by this Agreement.

When subcontracting, Company will make a reasonable effort to give preference to
subcontractors who are signatory to an International Brotherhood of Electrical
Workers contract. Notwithstanding the above, the Union

<PAGE>

agrees to cooperate with the Company in meeting its commitments to the U.S.
Government to subcontract work to minority businesses.

With respect to the installation of telephone systems wiring to be performed at
a location located fifty (50) miles or less from the domicile of a technician,
the Company agrees it will not subcontract any such work without first ensuring
that none of the employees in the Geographic Location are on lay-off status and
such action will not cause a loss of work opportunities to employees covered by
this Agreement. Moreover, the Company agrees that subcontracting will not be
used as a substitute for the hiring of technicians.

Notwithstanding the above, the Company reserves the right to subcontract work to
its authorized and certified dealers when it is requested by a customer or a
dealer. The International Office of the International Brotherhood of Electrical
Workers in Washington, D.C. shall have the right to verify whether a dealer is
authorized and certified by contacting an independent third party.

The Company reserves the right to select the employees to be assigned to this
work. Should it become necessary for the Company to subcontract work normally
performed by employees in this bargaining unit, the International Office of the
Union will, if it believes the Company did not give reasonable consideration to
the employees in the bargaining unit, bypass the grievance procedure and refer
the issue to the Home Office of the Company.

Senior Field Service Engineers shall be appointed and retained in said
classification by fulfilling and maintaining the standards as set forth in
Schedule "A" which is incorporated by reference to this Agreement. The Company
shall determine at its exclusive discretion the work to be performed by Senior
Field Service Engineers.

Field Service Engineers shall be appointed and retained in said classification
by fulfilling and maintaining the standards as set forth in Schedule "A" which
is incorporated by reference to this Agreement. The Company shall determine at
its exclusive discretion the work to be performed by Field Service Engineers.

Master Technicians shall be appointed and retained in said classification by
fulfilling and maintaining the standards as set forth in Schedule "A" which is
incorporated by reference to this Agreement. The Company shall determine at its
exclusive discretion the work to be performed by Master Technicians.

Technicians shall be appointed and retained in one of four levels by fulfilling
and maintaining the standards as set forth in Schedule "A" which is incorporated
by reference to this Agreement. The Company shall determine at its exclusive
discretion the work to be performed by Technicians.

                               HOURS AND OVERTIME

Section 5.A. The normal work schedule for all employees covered by this
Agreement shall consist of five (5) consecutive days, Monday through Friday,
inclusive, in each calendar week. The Company shall give employees at least one
(1) calendar week's notice of a change in their work schedule.

The two (2) days on which an employee is not scheduled to work shall be
scheduled days off, and shall be designated as the "first scheduled day off" and
"second scheduled day off". The first scheduled day off shall be Saturday. The
second scheduled day off shall be Sunday.

Assignments for Sunday work shall be distributed as equally as possible,
dependent upon the character of work to be done, among the employees of a
particular Geographic Location.

Subject to the overtime provisions of this Section, the workday of employees
shall be scheduled between 8:00 a.m. and 8:00 p .m., except as provided in
Section 5 .C. If the normal workday shift starts after 9:30 a.m. the Company
shall first seek volunteers for such shift. Should an insufficient number of
individuals volunteer then the Company may assign by inverse seniority an
individual to such shift.

The Company retains the right to schedule employees on a regular basis for five
(5) consecutive days, Tuesday through Saturday, inclusive. If an employee is
scheduled for five consecutive days, Tuesday through Saturday, he will be paid
time and one-half for hours worked on Saturday and double time for hours worked
on Sunday. The

<PAGE>

Company shall first seek volunteers for such shift. Should an insufficient
number of individuals volunteer, then the Company may assign by inverse
seniority individuals to such shift. For the purpose of overtime, Monday shall
be considered the "first scheduled day off" for an individual assigned to this
shift.

All employees, during their regular scheduled workday, shall have a lunch
period, without pay, of not less than thirty (30) minutes or more than one (1)
hour, as determined by mutual agreement between the Manager and the respective
Local Union involved. If an employee is scheduled to work and actually works ten
(10) hours or more in a day, the Company shall allow him a second meal period,
without pay, of not over thirty (30) minutes. If the meal period is actually
taken, the Company shall reimburse the employee $8.50 to cover the cost of the
meal.

Whether or not an employee has been previously scheduled to work on a holiday or
on one of his scheduled days off and is called into work such days, or is
recalled to work after completing a day's assignment, he shall receive not less
than the equivalent of six (6) hours' pay at his basic salary rate (straight
time rate), provided that any amount paid for hours actually worked shall be
credited against such minimum guarantee. Notwithstanding the above provision, if
a technician handles a service call over the telephone under the provisions
provided for under this paragraph, he shall receive not less than one (1) hours'
pay at his straight time rate. In accordance with this provision, Technicians
may be required to carry and/or wear a mobile communications device provided to
them by the Company.

Section 5.B. Consistent with efficient operations, overtime shall be distributed
equitably among employees in each occupational group. As much advance notice as
practicable will be given each employee required to work overtime. Notice will
be given no later than the end of an employee's workday when he is required to
work overtime on his next scheduled workday and no later than the end of the
employee's second workday prior to his first scheduled day off when he is
required to work on his first scheduled day off. When conditions make it
impracticable to give advance notice of overtime requirements, an employee will
be expected to work such overtime unless he has a bona fide reason for
declining. Overtime and premium time shall be paid for as follows:

Time and one-half shall be paid (except in those states where the law requires a
greater payment):

(1) for hours worked in excess of eight (8) hours in a day;

(2) for hours worked in excess of forty (40) hours in a calendar week, provided
that time and one-half shall be paid for hours worked in excess of thirty-two
(32) hours if one of the holidays designated in this Agreement falls on one of
the employees five (5) regular workdays; and

(3) for hours worked on Saturday (except for travel per Section 10(b)).

Double time shall be paid for hours worked on Sunday (except for travel per
Section 10(b)).

Holiday double time shall be paid for hours worked on any holiday designated in
this Agreement, such payment to be made in addition to the employee's basic
salary

Section 5.C. The normal scheduled workday shall be scheduled in advance and
shall consist of a regular day shift of eight (8) hours between 8:00 a.m. and
8:00 p.m. except for employees assigned to a night shift. The term "night shift"
shall mean any shift of eight (8) consecutive hours exclusive of meal periods,
Monday through Friday, starting before 6:00 a.m. or at or after 1:00 p.m.
Employees qualified to perform the available work shall be required to work
night shifts on the basis of seniority; the most senior of the qualified
employees shall be offered first opportunity to work such shift and, if
necessary, the next senior employee until the employee with the lowest seniority
is reached, which lowest senior employee shall be required to work the night
shift. Assignment to a night shift shall be scheduled one week in advance and
shall be for at least one (1) workweek. The scheduled starting time of a night
shift shall be the same each workday during any one workweek. Employees shall
not be required to work night shifts for a continuous period of more than ninety
(90) days in any one hundred eighty-- (180) day period. A night shift
differential of twelve per cent (12%) per hour shall be paid in addition to the
straight time base rate for hours worked Monday through Friday on a night shift
and shall also be paid in addition to the applicable overtime rate for hours
worked before or after a scheduled night shift and for hours worked on a night
shift on a holiday, Saturday or Sunday. An employee shall not receive the night
shift differential for hours worked before or after a regular day shift. No
employee shall be required to work more than six (6) hours without being given a
meal period, as defined in Section 5.A., such meal period to be given after the
third hour and to be completed by the sixth hour.

<PAGE>

Time and one-half shall be paid for hours worked before the beginning of or
after the ending of the employee's scheduled workday (regular day shift or night
shift). If an employee is called in before the commencement of the employee's
scheduled workday and works at least eight (8) hours, there shall be no
guarantee of work for any hours remaining in the employee's scheduled workday.
When an employee is required to report to work without being given at least
eight (8) hours off after the completion of his previous work period of not less
than eight (8) hours, he/she shall be paid at the overtime rate for all time
worked during the succeeding work period.

When the longest period worked in a calendar day is less than eight (8)
consecutive hours, the Company will pay an employee, who is available for work,
at a straight time rate for the difference between the number of hours worked in
one such period and eight (8) hours. In computing the payment due under this
provision for hours not worked, no other Section of this Agreement shall apply,
except that hours paid in accordance with Section 5.A. for call-in shall be
considered as time worked. This provision shall not apply to scheduled days off
holidays or temporary closings because of weather conditions, power failure, an
Act of God or other circumstances beyond the Company's control. For purpose of
this paragraph only, except for employees assigned to a night shift which
includes midnight, hours of work performed before midnight will be considered as
performed in the calendar day starting at midnight. For employees assigned to a
night shift Which includes midnight, the calendar day will be the twenty-four
(24) hour period beginning with the starting time of the employee's scheduled
workday.

Any employee scheduled to work during the period of time that commences eight
(8) hours after the end of his regular shift and 2 hours prior to the start of
his regular shift shall continue to be paid at a rate of 1-1/2 times his regular
rate until he receives at least eight (8) hours rest period (excluding
call-outs).

Section 5.D, Depending on business and market needs, the Company will determine
the need for stand-by duty for after-hours call-outs, and the number of
technicians required in each location. Stand-by duty assignments will be done on
a voluntary basis by Company seniority. However should an insufficient number of
volunteers be available to meet the requirements, assignments will be rotated on
an inverse seniority basis.

Stand-by is defined as being available and responding to call-out when called
(i.e., travel outside the coverage area is restricted).

For stand-by duty the Company will provide compensation of       plus a minimum
of 3 hours at straight time rate when called-out and dispatched to customer
location.

In situations where a technician is not on stand-by duty, but responds to and
accepts a dispatched call, compensation shall not be less than the equivalent of
six (6) hours basic salary rate (straight time rate).

                            CONTINUOUS SERVICE CREDIT

Section 6. Each employee shall have continuous service credit with the Company
dating from the first date of unbroken service with the Company or any of its
predecessors.

The continuous service credit and seniority of an employee will be broken under
the following conditions, and when so broken such employee shall be for all
purposes considered a new employee if and when rehired:

(a) Resignation or other voluntary termination of employment.

(b) Discharge for just cause.

(c) Absence in excess of three (3) consecutive working days without notice,
either by telephone or written message to the District Operations Manager
("DOM"), or his designee, unless satisfactory evidence of inability to so report
is shown.

(d) Unauthorized absence after the time limit of an authorized vacation or an
approved absence, unless satisfactory evidence of inability to report for work
is shown.

<PAGE>

(e) Failure to report to work after layoff within seven (7) calendar days after
indicating willingness to accept reinstatement when the Company has given the
employee written notice to return to such work or failure to notify the Company
of his intention to return to work within seventy-two (72) hours after such
notice is mailed. Such notice shall be deemed to have been sufficiently given if
sent to the employee by certified mail to the last address furnished by the
employee to the Company. A copy of such notice shall also be sent to the Local
Union involved.

Layoff without recall to work within three years from the date of such layoff.

                                    SENIORITY

Section 7. Based upon an employee's continuous service credit and subject to the
following conditions, an employee shall have seniority in a "Geographic
Location," and an "occupational group" as those terms are described in the
attached Schedule B, which is made a part hereof.

Each new employee shall be hired as an introductory employee and shall not have
seniority untill the end of an introductory period of thirty (30) days. The DOM,
with the concurrence of the Local Union and the introductory employee, may
extend the introductory period for up to sixty (60) additional days; in which
event the Company's Human Resources Department shall so inform the International
Office of the Union. Upon completion of the introductory period, the employee
shall be considered as a regular employee and shall have seniority from date of
hire. When thus established, such seniority will equal the employee's continuous
service credit. There shall be no requirement that the company reinstate or
rehire introductory employees if they are discharged during their introductory
period. During the period of introductory employment, an employee shall work
under the conditions established in this Agreement and shall receive not less
than the minimum rates of pay as provided in the attached Wage Schedules.

Credit for continuous service and seniority shall accumulate for two (2) years
while an employee is on leave of absence, except for employees on a leave of
absence for personal reasons. If an employee takes a leave of absence to serve
in the Armed Forces, he shall continue to accumulate credit for continuous
service and seniority for the period of such leave of absence.

Duly designated Shop Stewards and the President, Vice President, Recording
Secretary, Financial Secretary, Treasurer, Business Manager, and the Executive
Board Members of a Local Union shall have top seniority for layoff purposes in
their occupational group in their Geographic Location only if they perform
steward-like functions, i.e., grievance processing or other on-the job contract
administration responsibilities and only to the extent allowed by law.

The Company shall supply the respective Local Unions with a seniority list of
the employees covered by this Agreement within each Geographic Location. Such
list shall be revised quarterly. The Company shall also provide the Local Union
involved with the names of all new employees and those who have been permanently
transferred or terminated.

                               SENIORITY TRANSFERS

Section 7A. An employee who is permanently transferred to an established
Geographic Location at his own request shall retain his seniority in the
Geographic Location from which he was transferred for a period of three (3)
months. Thereafter, he shall have seniority in the Geographic Location here then
employed equal to his total length of service in such Geographic Location, plus
a seniority credit equal to fifty percent (50%) of his previous unbroken
seniority with the bargaining unit. After an additional nine (9) months' service
in such Geographic Location, he shall be given an additional seniority credit
equal to twenty-five (25%) of his unbroken seniority within the bargaining unit
prior to this permanent transfer.

An employee who is permanently transferred outside a given Geographic Location
at the request of the Company, or who is permanently transferred to a newly
established Geographic Location, shall retain full seniority credit as is in
effect at the date of transfer.

<PAGE>

                                     LAYOFFS

Section 7B. In the event of a layoff, the least senior employee within the
Occupational Group selected by the Company within the geographic location where
there is a lack of work, will be displaced. An employee who is displaced will
have the opportunity to bump the least senior employee within his occupational
group who is in his Geographic Location, provided that the displaced employee
chooses to travel to the Geographic Location where the work needs to be
performed during non-work time and at his own expense.

In the event of layoff, an employee shall receive a gratuity payment equal to
two (2) times his/her vacation entitlement.

                                 REINSTATEMENTS

Section 7C. When additional employees are needed in any Geographic Location,
employees who have been laid off shall be offered reinstatement in the reverse
order in which they were laid off before the positions are filled by the
transfer of employees with less seniority or by the employment of new employees.
Notification of opening for reinstatement shall be given by the Company, by
certified mail, to the last address furnished by the employee to the Company. A
copy of such notice shall also be sent to the Local Union involved. Within
ninety-six (96) hours after such notice is received by the laid off employee,
the laid off employee must advise the Company whether he accepts such
reinstatement. If no reply is received by the Company within 7 days after the
notice is mailed, the next employee on the seniority list may be notified of the
opening. If no employee remains on the seniority list, a new employee may be
hired. Employees recalled shall report to work within seven (7) calendar days
after indicating their willingness to accept reinstatement. If they fail to
report within such time, they shall lose their seniority rights. It will be the
responsibility of the laid-off employee to keep the Company and Union advised of
the employee's current mailing address.

                                WORK ASSIGNMENTS

Section 7D. The Company has the right to assign any type of work to an employee,
and to rotate employees between locations in a Geographic Location. However,
consideration will be given to seniority in making such work assignments.

                                    TRANSFERS

Section 8. An employee may be temporarily assigned to work at any location in
the United States. Such assignment shall normally not exceed thirty (30) days
except that employees may be required to remain at the customer location for
periods exceeding thirty (30) days as necessary to complete the assignment. An
employee who is assigned a temporary remote job that requires the employee to be
away from home from Monday through Friday of the following week will be allowed
the two week-end days (i.e. Saturday and Sunday) actually at home. However, no
employee may be permanently transferred without his consent. When transferred
either on a temporary or a permanent basis, the employee shall be permitted by
the International and Local Unions of the IBEW to work at the assigned location.

The Company shall reimburse the employee for any reasonable expenses that are
incurred by him in connection with any temporary assignment or permanent
transfer which is made at the request of the Company but the Company shall not
be liable for any expenses incurred by an employee in connection with any
assignment or transfer which is made at the request of the employee. Transfers
effected within a Geographic Location as a result of applying the seniority
provisions of this Agreement shall be made solely at the expense of the employee
involved. In cases of temporary transfer, the employee, upon request, shall be
advanced not less than two weeks' prepaid expenses.

                               GRIEVANCE PROCEDURE

Section 9. If there is any grievance, dispute by any employee covered by this
Agreement or Union with respect to the interpretation or application of any
provision of this Agreement, such grievance, dispute or difference shall be
reduced to writing and processed in accordance with the following steps in this
grievance

<PAGE>

procedure, provided, however, that any individual employee, or group of
employees, shall have the right at any time to present verbally, or in writing,
complaints or grievances to the Company and to have such grievances adjusted,
without the intervention of the Union, as long as the adjustment is not
inconsistent with the terms of this Agreement, and provided the Union's
representative has been given an opportunity to be present at such adjustments.

Step One. The grievance shall be submitted to the aggrieved employee's DOM if
the employee's Steward and the DOM fail to settle the grievance within three (3)
days, it may be submitted to Step Two.

Step Two. The Region Director and the Union's Business Representative shall
attempt to settle the grievance. If no settlement is reached within five (5)
days, the grievance may be submitted to Step Three. The Company's Human
Resources Department shall be copied.

Step Three. The President and Chief Operating Officer of the Company, or his
designated representative, and the International President of the Union, or his
designated representative, shall attempt to settle the grievance. If no
settlement is reached within a reasonable time (not to exceed thirty (30) days),
the grievance may be submitted to arbitration as set forth in Step Four.

Step Four. Any grievance not satisfactorily disposed of in accordance with the
steps of the grievance procedure above may be submitted to arbitration under the
voluntary arbitration rules then obtaining with the Federal Mediation and
Conciliation Service except the Arbitrator shall be selected as follows: The
Federal Mediation and Conciliation Service shall submit as soon as possible, to
each of the Parties, duplicate lists of the names of seven (7) persons qualified
to act. The Union and the Company shall within ten (10) days from the receipt of
such lists, indicate the order of preference, if any, for names on their
respective lists. These lists shall be returned to the FMCS which shall,
thereupon, select the Arbitrator from the name or names remaining.

The Parties agree that the decision or award of such Arbitrator shall be final
and binding on each of the Parties and that they will abide thereby, subject to
such laws, rules and regulations as may be applicable. The authority of the
Arbitrator shall be limited to determining questions directly involving the
interpretation or application of specific provisions of this Agreement, and no
other matter shall be subject to arbitration hereunder. The Arbitrator shall
have no authority to add to, subtract from, or to change any of the terms of
this Agreement to change an existing wage rate or to establish a new wage rate.
In no event shall the same question or issue be the subject of arbitration more
than once. Each Party shall bear the expense of preparing and presenting its own
case. The cost of the arbitrator's services and any other expenses incidental to
the arbitration, mutually agreed to in advance, shall be borne equally by the
Parties.

All grievances shall be presented as soon as practicable after the occurrence
upon which the same is based, but in no event later than seven (7) days if the
same is a dismissal grievance or later than thirty (30) days if the grievance
arises from any other cause.

The failure to submit a grievance within such periods shall constitute a bar to
further action thereon. If it is determined under the grievance procedure,
including arbitration, that any adjustment in wages is appropriate, such
adjustment shall be based upon existing wage rates, and shall be applied
retroactively to the date of occurrence, provided that such date is not more
than thirty (30) days prior to the date upon which the grievance was presented.

The Company will consider reprimands or disciplinary action against an employee
as cleared from his record after an eighteen (18) month period from the date of
issuance; provided that there have been no further infractions during that
period. The employee's record may be cleared earlier when, in the judgment of
the Company, his past service record warrants such action.

                           TRAVEL AND LIVING EXPENSES

Section 10. Employees who are required by the Company to travel on Company
assignments shall be compensated as follows:

<PAGE>

(a) when temporarily transferred outside the Geographic Location on productive
work assignments, a travel allowance at the applicable rate, calculated on his
regular base rate of pay for all time required, not to exceed eight (8) hours in
any one (1) day.

(b) When traveling for instructional purposes and other nonproductive
assignments, a travel allowance for the time spent in such travel, not to exceed
eight (8) hours in any one day, at the employee's straight time rate of pay
without regard for whether such travel is on a Saturday or Sunday.

When an employee is required to report directly from his residence to a work
location other than within his assigned Geographic Location, the time spent in
travel which is in excess of the normal travel time between his residence and
his assigned Geographic Location and toll charges which are in excess of those
normally required in travel between his residence and his assigned Geographic
Location shall be paid. There shall be a maximum of forty-five (45) minutes
normal travel time for those Technicians on truck take home. The Company shall
determine the amount of the excess travel time and it shall be paid at the
employee's applicable rate calculated on his basic wage rate.

The time and method of traveling shall be subject to Company instruction.

Each employee shall be reimbursed by the Company for reasonable living expenses
incurred by him while away from the city assigned as his base of operations,
provided that no such reimbursement shall be made for any particular day unless
the employee is required to use a hotel because the distance between his
location at the end of the day and his assigned base of operations, or other
circumstances, prohibits his return to the city in which his base of operations
is located. Employees are to submit valid expense reports in a timely manner.
Approved expenses will be paid through the accounts payable system generally
within three weeks of submission.

                                   AUTOMOBILES

Section 11. No employee shall be required, as a condition of employment, to
furnish an automobile for use in connection with his work.

                                    VACATIONS

Section 12. Employees who on January 1 of each year have continuous service
credit as set forth below will be entitled to an amount of vacation in
accordance with the following schedule to be taken during the subsequent twelve
(12) month period:

<TABLE>
<CAPTION>
Continuous Service Credit                               Vacations
-------------------------                               ---------
<S>                                                     <C>
More than 6 months but less than 1 year                  1 week
1 year but less than 5 years                             2 weeks
5 years but less than 10 years                           3 weeks
10 years or more                                         4 weeks
25 years or more                                         5 weeks
</TABLE>

The vacation year will begin on January 1 and end on December 31. For the
purposes of determining vacation entitlement, continuous service credit does not
accrue while an employee is on layoff or leave of absence.

Employees will be paid at their regular rate of pay for any vacation time which
they take. Payment in lieu of taking accrued vacation will not be allowed.
Employees may carry over a maximum of five (5) days from one vacation year to
another. An employee will be entitled to an additional vacation day if a paid
holiday falls during his vacation.

Employees must be on the active payroll on January 1 to be eligible for vacation
benefits for the subsequent year. An employee who is terminated for any reason
will be granted payment for vacation time which had accrued in the preceding
vacation year but was not taken in the current year. In addition, where required
by state law or when an employee retires, accrued vacation will be paid on a
prorated basis.

<PAGE>

Vacation scheduling must be approved in advance by the DOM. The DOM, or his
designee will consider an employee's seniority in making vacation scheduling
decisions, provided that doing so is consistent with the Company's efficient
operations.

                                    HOLIDAYS

Section 13. The following holidays shall be observed: New Years' Day, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day. Four (4)
personal holidays will be observed by all employees covered by this Agreement
during the period January 1 to December 31 of each year. Each employee shall
select the day he desires to celebrate such holidays except that such holidays
shall be distributed evenly across the period for each seniority group. Choice
of the holidays shall be governed by seniority.

For the term of this Agreement other recognized holidays may be observed in
place of Memorial Day and the four (4) personal holidays on the basis of a local
understanding between the Local Union Business Representative and the Company
Regional Director, subject to the approval by the Human Resources Department of
the Company and the International Office of the Union. In the absence of any
local agreement with respect to these five (5) holidays, the above named
holidays shall be observed. When any holiday designated in this Section falls on
Sunday, and Monday is the day commonly observed for that holiday, such Monday
shall be considered as the designated holiday. When any holiday designated in
this Section falls on a Saturday, and Friday is the day commonly observed for
that holiday, such Friday shall be considered as the designated holiday. In the
event that a designated holiday falls on an employee's designated day off other
than Saturday or Sunday, the DOM, or his designee, shall grant the employee his
next scheduled workday off, or permit the employee to select any day off within
the next fourteen (14) calendar days. In order to qualify for holiday pay, an
employee must work his scheduled day before and after the holiday unless excused
in writing by medical authority.

The Company shall pay employees at their straight time hourly base rate not to
exceed eight (8) hours for each of the above-designated holidays. Employees who
are required to work on any one of the designated holidays shall be paid at two
times their straight hourly base rate for hours worked. Such payment to be made
in addition to the employee's basic salary. An employee who is on jury duty,
appearing as a subpoenaed witness in court or on non-war military duty shall
receive holiday pay in accordance with this Section instead of the payments
provided for in Section 17.

                            AGREEMENT AGAINST STRIKES
                                  AND LOCKOUTS

Section 14. There will be no strike, refusal to work, slowdown, sit-down,
picketing, or boycott by the Union or its affiliated Locals or members, or
lockout on the part of the Company during the term of this Agreement, provided
that a member of the Union may refuse to enter upon the premises of any employer
other than the Company if the employees of such employer are engaged in a strike
ratified or approved by a representative of such employees whom such employer is
required to recognize pursuant to an applicable state law or the labor
Management Relations Act of 1947, as amended.

In consideration of this Agreement, the Union agrees not to sue the Company, its
officers or representatives, and the Company agrees not to sue the Union, its
officers, agents or members for any labor matters in any court of law or equity.

assignment is prohibited or void, upon receipt of an employee's written
authorization which shall not be irrevocable for more than one year, or beyond
the termination day of this Agreement, whichever occurs sooner, the Company
shall deduct from such employee's wage on the second bi-weekly pay day of each
month the Union dues and remit same to the duly authorized representative of the
Union, together with a list of names of the employees from whose pay deductions
were made.

Within thirty (30) days after receipt of a written authorization from the
employee, the Company will deduct an amount equal to the reasonable initiation
fee uniformly required as a condition of acquiring membership in the Union and
will remit said amount to the duly authorized representative of the Union,
together with a list of the names of the employees from whose wages such
deductions were made.

The Local Union agrees to hold the Company free from all liability in connection
with dues and/or initiation fee collection except for ordinary diligence and
care in transmittal of the monies to the Local Union, and further agrees that
the Company will not be required to deduct from an employee's wages both Union
dues and initiation fees in the same month.

for each such absence and up to eight (8) hours per day.

If an employee is entitled to receive, upon proper application, weekly
disability benefits under the California Unemployment Insurance Code for the
same period when he is also eligible for "absence payments" under this Section,
the Company will pay such "absence payments" if otherwise eligible, in an amount
equal to the difference between the employee's basic weekly rate and the amount
paid to the employee under the California Unemployment Insurance Code.

If an employee is entitled to receive temporary disability benefits under any
State Workers Compensation Law and state law provides that such benefits must be
paid to the employee regardless of his pay status, any "absence payments" under

additional six (6) months, without pay, with service credit and seniority
accumulating. If the disability continues beyond one (1) year, the employee
shall receive additional leaves of absence, without pay, not to exceed six (6)

                                   SCHEDULE A

Introduction

The Company maintains four occupational groups within its represented field
technical group. Each occupational group has specific requirements that must be
met. New hires can be assigned to any occupational group provided they meet the
necessary requirements. After a new hire completes his introductory period, he
can request that his Status be reviewed to determine if he should be placed at a
higher Technician level. In the event that such employee is not placed in a
higher Technician level, he may avail himself of the grievance procedure to
contest such action.

The Company reserves the right to require re-certification of any employee in
any occupational group when it has reasonable cause to believe such employee
does not fulfill the requirements for such position. An employee who fails to
pass a re-certification will be given six months to re-certify. If the employee
fails such second attempt to pass the re-certification such employee may be
reclassified. In the event an employee who has been re-classified again fails to
re-certify at his former level within a six (6) month period, such employee will
be subject to termination. In the event that an employee is re-classified or
terminated, he may avail himself of the grievance procedure to contest such
demotion or termination.

Notwithstanding the above, the Company has the right to require re-certification
of senior field service engineers every two (2) years at the direction of the
Company.

Training

The District Operations Manager will develop with each employee covered under
this Agreement a mutually agreed upon training plan to aid each such employee in
his or her efforts to obtain the requisite training to maintain his or her job
classification during the term of this Agreement. As a part of the training
plan, each such employee may, as required in each individual case, be scheduled
for up to one hundred twenty (120) personal training hours during the term of
this Agreement. The Company will make a good faith effort to ensure the employee
scheduled for personal training is not interrupted during the scheduled time to
perform service.

On at least a yearly basis, the Company will meet with the Union to review the
criteria which is taken into account in deciding who is selected for products
specific training, when they are selected, on which equipment they are trained,
and how the procedure will be performed in the future.

In deciding which employees are trained on which equipment, a major factor that
will be taken into account is what type of equipment is installed and serviced
in the Geographic Location in which the Technician works.

Any training provided to members of a particular job classification in a
particular Geographical Location will be offered on a seniority basis provided
the senior person or persons have the requisite minimum skills and attributes
necessary to make such training mutually advantageous to the Company and
employee.

In order to help ensure that an employee may maintain competence at his level,
and improve upon already existing skills, the Company will provide training
which is specific to the equipment that the technician is expected to install
and service. It is the employee's responsibility, however, to seek out and
acquire general technological training which is generic in scope. In order to
assist an employee in acquiring such training, the Company has implemented a
tuition reimbursement program. Employees will reimburse the Company for any
moneys the Company expends in providing non product specific training, which is
intended to lead to certification, by an independent party, to the extent the
employee leaves the Company on his/her own volition within two (2) years of
receiving such training. The training will-be deemed to have been received at
such time as the employee becomes certified or fails to pass the certification
test. The Company will have employees sign an agreement with respect to such
before employee enters the program.

Evaluation

Employees will be given annual performance evaluations. One component of this
evaluation will be customer

<PAGE>

satisfaction, but only as it relates to the performance of the employee. The
Company may, in its sole discretion, provide remuneration based on customer
satisfaction and recognition upon achievement of a higher level of
certification. However, such remuneration shall not be part of, or included in,
an employee's wage rate. The Company may also, in its sole discretion, provide
recognition to employees who achieve outstanding customer satisfaction.

In no event will said performance evaluation be used, however, to discipline an
employee, but it may be utilized to develop a plan for improvement in areas
where the Company has determined it is required.

Dear Mr. Barry:

This is to confirm the understanding reached between Mitel Communications
Solutions, Inc. (the "Company") and the International Brotherhood of Electrical
Workers (the "Union") regarding potential Geographic Location wage
differentials.

Subsequent to the ratification of the collective bargaining agreement recently
negotiated between the parties, the Company will consider the application by any
local Union for a wage rate differential in excess of the negotiated rates based
upon such considerations as the cost of living and market conditions in a
particular Geographic Location.

It is understood and agreed that this letter shall be effective only for the
duration of the recently negotiated collective bargaining agreement, unless
terminated at an earlier date by mutual consent of said parties.

FOR THE UNION:                           FOR THE COMPANY:

      RE:  Special Skill Work

Dear Mr. Barry:

This is to confirm the understanding that from time to time, the Company may
have opportunities which involve work which requires skills or knowledge not
possessed by its bargaining unit employees. The parties agree that the Company
may subcontract this work notwithstanding any limit on its right to subcontract
contained in the collective bargaining agreement. However, the parties agree
that this side letter will not be utilized to avoid training bargaining unit
employees to do this work. Rather, in the event the Company reasonably expects
the demand for a particular type of work or skill to continue for longer than
six (6) months, the Company will attempt to develop its employees to meet the
