                                    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:

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 until 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

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

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,

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

-------------------------                               ---------
<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.

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.

                                   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.

      RE:  Geographic Location Wage Differentials

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:

Dear Mr. Barry:

This is to confirm that neither this collective bargaining agreement nor its

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") with respect to secondary and tertiary markets.

term of this Agreement continue to be, in the process of selling off its
installed base of customers in certain secondary and tertiary markets to

"Dealers"). The Company agrees to use its good faith, best efforts to encourage
said Dealers to employ technicians affected by this process on mutually
satisfactory terms and conditions.

      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
demand.
