Value Added Resellers (VARs) to market, sell, install, and maintain certain of
its most leading edge products in a way that meets Mitel's highest standards in
order to enhance the goodwill of the Mitel name and product lines in the
industry. Mitel has two VAR levels, VARs which primarily sell the traditional
Time Division Multiplexor ("TDM") product lines (e.g. SX-200 & SX-2000),
however, Elite VARs also have the ability to sell Mitel's Voice Over Internet
Protocol ("VOIP") product family, as well, under certain restricted conditions;

sell Mitel's various desktop devices, as well as, Mitel peripherals, including
Mitel's messaging offerings.

the parties hereto, the parties, intending to be bound, hereby agree, in
writing, as follows:

Mitel as an Elite VAR or as a Platinum Elite VAR. A traditional hard copy of the
appropriate price list is also available from Mitel upon request but Mitel
reserves the right to charge a fee for such. Such price list is incorporated by
reference herein. Mitel will update the Mitel Caribbean Price List from time to
time. Mitel will provide VAR thirty (30) day's prior written notice, via Mitel
On-Line of any price changes and/or additions to such. It is the responsibility
of the VAR to periodically review the price list in order to ensure it has
current pricing when providing quotations to end users. VAR also agrees to

subject to applicable terms and conditions, disclaimers and warnings regarding
its utilization. VAR agrees to keep the Mitel Caribbean Price list strictly
confidential. Mitel PRODUCTS will be sold and/or licensed (in the case of
software) to VAR directly from Mitel.

         b) VAR agrees to sell or sub-license (in the case of software) Mitel
PRODUCTS only to its own end-user customers for installation and use in the
Caribbean; VAR agrees not to sell (or trans-ship) Mitel PRODUCTS to wholesalers
or other value added resellers or dealers, interconnects or brokers of
communication solutions (whether authorized resellers of Mitel or otherwise)
without first obtaining the express written consent of an Officer of Mitel.

         d) This appointment by Mitel is nonexclusive, and Mitel expressly
reserves the right, in its reasonable discretion, to appoint other VARs who are
in competition with VAR, as well as to sell through telephone companies
(hereinafter referred to as "telcos"), as it sees fit, from time to time
hereafter. Mitel also reserves the right, in its reasonable discretion, to
hereafter develop new channels of distribution through which certain new
PRODUCTS may be best sold including but not limited to CLEC's, ISP's, Carriers
and Data VARs). Access to such channels will be based on meeting certain
standards as set by Mitel from time to time in its reasonable discretion.

         e) VAR agrees to use its best efforts to legally and ethically promote
the sale, lease, licensing, installation, service, and maintenance of all

                                     Page 3                            June 2001
<PAGE>
PRODUCTS in its assigned territory. VAR likewise agrees not to tortiously
interfere with the advantageous contractual and/or business relationships of
other Mitel authorised VARs and/or distributors of PRODUCTS or the provision of
services for Mitel PRODUCTS (e.g., installation and/or maintenance) inherently
related to such. VAR also understands and agrees to the implied covenant of good
faith and fair dealing as well as agreeing to abide by fair trade practices with
respect to the purchase and sale of Mitel PRODUCTS and the provision of services
for such.

2. TERM. This Agreement shall commence upon execution, and expire on April 30,
2002. Mitel may elect to renew the agreement for an additional one year term
provided Mitel has given notice of such no later than April 1, 2002. This
Agreement also may be terminated in accordance with Paragraph 14 hereinbelow.
Unless otherwise stated herein, "yearend" or "fiscal year end" shall be April
30th and a number of days shall be considered as calendar days. For Financial
accounting purposes it is understood that Mitel closes its books on its year on
the last Friday in April each year.

3. TERRITORY.

         a) VAR's Primary Area of Responsibility (herein after referred to as
"PAR") for the distribution and support of Mitel PRODUCTS shall be as listed on
SCHEDULE A attached to and made a part of this Agreement. Mitel may authorise,
in its reasonable discretion, distribution of Mitel PRODUCTS by VAR outside of
VAR's PAR on a case by case basis or on a pre-approved blanket basis in certain
instances. VAR is required to obtain prior written permission from Mitel,
however, before attempting to make sales of Mitel PRODUCT outside its PAR. VAR
must assure Mitel that all proposed sale will be installed, supported and
maintained in strict accordance with Mitel standards and in conjunction with, if
reasonably necessary, an authorised Mitel VAR operating in the area where the
Mitel PRODUCTS is to be installed or by Mitel itself if it has such
capabilities in the area where installation is to occur. VAR is also required to
comply with Mitel's Out-Of-PAR Permission Policy which is available for review
via Mitel-OnLine.

         b) In the event of unauthorized sales of Mitel PRODUCTS outside of the
PAR, said sales do not count towards VAR's Minimum Purchase Requirement (MPR),
as hereinafter defined. Mitel may also declare a default or material breach
under this Agreement for disregard of this covenant by VAR.

         c) VAR understands and agrees that Mitel may, in its reasonable
discretion, appoint other VARs within VAR's PAR (to overlap same in whole or in
part) as well as other channels (see paragraph 1c, above) and, in its
discretion, also may sell direct (including but not limited to through its
subsidiary Mitel Network Solutions, or through Telcos, or through Dedicated
Accounts sales within a VAR's PAR. VAR understands and agrees that Mitel may
consider, among other factors, the overall potential for Mitel sales in a PAR in
determining the appropriate number of VARs to have in a particular PAR. VAR
understands and agrees that it must first subscribe to the PAR where its
corporate headquarters is located before it may request another PAR (s)
elsewhere, contiguous or otherwise.

         d) VAR understands and agrees that Mitel has certain exclusive
arrangements with certain telcos and will not, therefore, award a PAR to an VAR
to sell Mitel Product in certain Caribbean areas.

         e) Only Mitel's Professional Services Group, VARs or Mitel authorized
resellers that also employ technicians certified by Mitel on the PRODUCTS to be
installed may be used as a Subcontractor or with respect to a Teaming or Agency
Agreement for the installation and maintenance of PRODUCT, whether in PAR or
Out-Of-PAR. If the VAR requesting Out-Of-PAR approval will or may utilise a
Subcontractor for performance, in whole or in part, of the Out-Of-PAR work, then
the VAR must also first identify and properly register the VAR, or Mitel
authorized reseller that is to be the Subcontractor, all in accordance with
Mitel marketing policy.

         f) To the extent VAR chooses to promote Mitel PRODUCTS via a web site
on the internet, VAR agrees to place the following statement in a prominent,
conspicuous location on all pages promoting Mitel PRODUCTS in no less than 12
point type and in all caps as follows: "THIS PROMOTION OF MITEL PRODUCTS IS NOT
INTENDED AS A SOLICITATION OF ANYONE LOCATED OUTSIDE OF OUR PRIMARY AREA OF
RESPONSIBILITY WHICH IS (at this point insert the name of the town(s) and/or
county(ies) that comprise your PAR(s)." Should VAR wish to advertise Product
pricing via their web site or otherwise via the internet, VAR shall comply with
Mitel's Web Advertising Policy read in conjunction

                                     Page 4                            June 2001
<PAGE>
with Mitel's Out-Of-PAR Permission Policy, as defined in paragraph 5(u) below;
additionally both policies are available for review via Mitel On-Line. VAR
understands and agrees that internet opportunities that are out-of-PAR are to be
handled exactly the same as non-internet opportunities in terms of the need to
obtain and receive prior written permission from Mitel before proceeding with a
particular sale or sales. Mitel reserves the right to audit compliance with this
provision and VAR agrees to co-operate with Mitel in complying with the spirit
of this provision to avoid the solicitation and acceptance of out of PAR
business without first seeking and obtaining Mitel's prior express written
consent for each such proposed sale.

4. MITEL'S OBLIGATIONS TO VAR.

         a) Materials/Documentation. Mitel agrees to provide VAR with a

corrections to Mitel software. When these new Release Levels are made available
commercially, they shall be provided at nominal cost to VAR if the new Release
Level is of a corrective nature. If, however, new features are incorporated in
addition to operational corrections and/or if the Release consists solely of new
features or functionality, then VAR still will be provided with

                                     Page 5                            June 2001
<PAGE>
the corrections as aforesaid, but new features will be made available to VAR at
the then current VAR price for such new features. Mitel reserves the right to
give sixty (60) days prior written notice that it will no longer provide
out-of-warranty after market technical support to a particular PRODUCT and/or

         h) Right to VAR Comfort Letter. Mitel, in its reasonable discretion,

Requirement (MPR) and shall be as delineated on SCHEDULE A. SCHEDULE A will

         b) Late Payment Interest. VAR agrees to timely pay for Mitel Products
ordered under the Agreement. At Mitel's option all amounts which are more than
fifteen (15) days past due shall accrue interest from the due date at a rate

please see paragraph 6(e) hereinbelow).

         c) Feature Mitel PRODUCTS. VAR agrees to feature Mitel PRODUCTS to its

1, 2003 if the Agreement is renewed. VAR agrees to supply true copies of all
invoices rendered by VAR during such period within twenty (20) days of a written
request by Mitel for such information. This requirement to feature Mitel
products only applies in situations where Mitel offers a viable competing
product. For example, Mitel will not, for the first term hereof, count sales of
messaging products above fifty (50) ports per installation in determining
whether or not VAR has met its obligation to feature Mitel product. Failure to
feature Mitel products shall constitute a material breach of this Agreement.

         d) Pursue Sales Leads. VAR agrees to timely act on sales leads
originating from Mitel and to offer only Mitel PRODUCT with respect to such
referrals.

         e) Maintain Customer Satisfaction. VAR agrees to participate in Mitel's
Customer Value Program (CVP). VAR is required to maintain a customer value
rating which is equal to or above an eighty percent (80%) score as determined by
Mitel. Mitel reserves the right to review VAR's rating and to take appropriate
action with VAR to improve its rating. Mitel will employ an independent
third-party to conduct surveys of VAR's customer base in order to ascertain the
degree of customer satisfaction VAR has attained, and VAR agrees to cooperate
with Mitel or a third-party to enable it to conduct such surveys. VAR is
required to provide a complete customer listing to Mitel on a quarterly basis.
Should VAR not provide Mitel a customer listing, Mitel reserves the right to
terminate VAR from the Mitel reseller program.

         f) Customer Service and Support Requirements. VAR agrees to comply with
the Mitel Customer Service and Support Requirements attached hereto and
incorporated by reference herein as SCHEDULE H as well as with the usual and
customary standards within the telecommunications industry. VAR agrees to
attempt in good faith to resolve customer complaints, and Mitel undertakes to
work with VAR to help accomplish same on a second line support basis. VAR

certified technicians on a per product per PAR basis (also see subparagraph 5
(h) below).

with those practices published from time to time by Mitel. Mitel agrees to

<PAGE>
published practices and technical service bulletins on a regular basis. In the
event VAR fails to perform its obligations to its customers, as per sub -
paragraphs "5e)" and "5f)" above, VAR agrees that Mitel shall have the right to
either provide such technical assistance itself or refer the said end-user to
another qualified Mitel authorized reseller. Before so proceeding, however,
Mitel agrees to give VAR prior notice of the problem and a reasonable
opportunity to promptly correct the matter. Should VAR then fail to take
appropriate corrective steps on a timely basis, it shall be responsible for
reasonable expenses incurred by Mitel in resolving the problem.

         h) Use Only Certified Technicians. VAR agrees that each and every
installation of Mitel PRODUCT shall be directly supervised and approved by a
qualified technician employed by VAR. VAR agrees that such technician shall be
certified by Mitel (at VAR's expense) as meeting the minimum standards necessary
to install and maintain the particular product in question in accordance with
Mitel conducted installation and maintenance courses in order that the goodwill
inherent in the Mitel name and product line is not harmed. VAR also agrees to
send its technicians at its own expense to Mitel courses regarding new Mitel
PRODUCTS and/or new Mitel software releases so that its technicians will
maintain the requisite proficiency level. VAR also agrees to employ an
acceptable number (in Mitel's reasonable discretion) of trained (Mitel
certified) technicians to support VAR's installed base of Mitel PRODUCT.
Attached hereto and incorporated by reference herein as SCHEDULE I is the
Certified Technician Training and Registration Plan which delineates the
undertakings of Mitel and of VAR relating to the training and certification of
technicians by Mitel. In order to achieve and retain certification, a technician
must be trained by Mitel, approved by Mitel as having successfully completed the
course of studies and received a passing grade in Mitel's reasonable discretion
and be employed by a Mitel authorized entity which duly registers the technician
with Mitel's consent and obtains the requisite continuing training deemed
reasonably necessary by Mitel to retain his or her certification. A technician
looses his or her certification if it has expired by its terms, if it has not
been maintained in terms of renewal and/or continuing training that is required
or if he or she is no longer registered by an authorized entity and approved by
Mitel. Mitel also reserves the right to cancel the registration of those
technicians no longer sponsored by an authorized entity (e.g., should a VAR lose
its dealership or should the VAR inform Mitel that a technician has left its
employ). Mitel also reserves the right to require a certified technician to take
a refresher course if he or she is deemed, in the reasonable discretion of a
Mitel Technical Account Manager to need such remedial assistance in order to
achieve customer satisfaction in Mitel's reasonable discretion. Please see
additional requirement with respect to training and certification as reflected
in SCHEDULE I.

         i) Limit Claims to Written Specifications. VAR agrees to limit its
claims and representations concerning Mitel PRODUCTS to those in conformity with
Mitel's published written specifications.

         j) Toll Fraud. VAR agrees not to expressly state or imply that Mitel
PRODUCTS provide technical immunity from fraudulent intrusion or toll fraud, and
VAR agrees to include in its agreement with its customer a warning concerning
the possibility of toll fraud occurring and a written disclaimer regarding
responsibility for same. VAR also agrees to follow the recommendations in the
Mitel Technical Service Bulletin series entitled "PABX--CDE Programming
Pertaining to Unauthorised Toll Calling Access".

         k) Security Interest/Set-off. VAR hereby grants to Mitel a purchase
money security interest in all Mitel Products for which Mitel has not been
timely paid either now possessed by VAR or hereafter acquired by VAR pursuant to
this Agreement (the "collateral") and in the proceeds of the sale of Mitel
PRODUCTS, as well as the proceeds of any insurance covering the collateral. VAR,
likewise, grants a right of set-off to Mitel regarding any monies owed by Mitel
to VAR.

         l) Product Demonstration Centre. VAR agrees to establish and maintain a
Product Demonstration Centre, within each assigned PAR, that prominently
displays and promotes Mitel Products. Mitel agrees to provide special pricing
and terms to VAR from time to time to enable it to equip its Product
Demonstration Centre with current products. VAR understands and agrees that it
may not re-sell any Product obtained through this program or the program
delineated in subparagraph 4 (x), above, regarding the Virtual Classroom Kit,
without first offering, in writing, to sell the PRODUCT back to Mitel at the
price originally paid to Mitel by VAR minus depreciation.

         m) Sales/Product Training. VAR agrees to have its sales staff
participate in the sales

                                     Page 9                            June 2001
<PAGE>
training Mitel makes available to VAR. VAR agrees to pay tuition costs and
associated expenses for participation in these courses.

         n) Supply Summary Financial Information. VAR agrees to provide to Mitel
such summary financial information as may be requested by Mitel, including
without limitation, balance sheet/profit and loss statements, upon application
to become a VAR and on an annual basis as requested by Mitel from time to time.

         o) Protect Confidential Information. VAR agrees to protect Mitel
confidential information and not to disclose such to others or use such except
for the purposes of this Agreement. Upon termination VAR likewise agrees not to
utilise such information in a way that is not in the best interests of Mitel.

         p) Extend Mitel Warranty. VAR agrees to extend a substantially similar
version of Mitel's Caribbean Product Warranty, attached hereto and incorporated
by reference herein as composite SCHEDULE B, to and in favour of its
customer(s), subject to the terms and conditions, disclaimers and limitations of
liability stated therein. VAR agrees to incorporate said warranty along with the
material terms, disclaimers, and limitations of liability of said warranty in
its written agreement with its customer. VAR agrees to provide customer(s), at
no charge to Mitel, with the warranty service inherent in honouring the
aforesaid Mitel warranty.

         q) Insurance. VAR agrees to insure Mitel PRODUCT purchased hereunder
from the point of receipt by carrier at Mitel plant, until an accepted
installation at customer's site has been achieved, against loss by fire, theft,
damage or other casualty, as well as to maintain products and public casualty
liability insurance covering the sale and installation of the Mitel PRODUCT.
Such insurance shall be in amounts acceptable to Mitel, and VAR agrees to
provide Mitel with a true copy of a certificate of insurance evidencing such
coverage upon Mitel's request.

         r) Indemnification. VAR agrees to indemnify, defend, and hold Mitel
harmless from any and all costs, expenses, damages, and liabilities arising to
Mitel as a result of a material breach of this Agreement by VAR or as a result
of negligent acts or omissions of VAR in performing hereunder. Mitel likewise
agrees to indemnify, defend and hold harmless VAR for any and all costs,
expenses, damages, or liability arising to VAR from a material breach by Mitel
of this Agreement, the terms and conditions of the Mitel Product Warranty, or
the negligent acts or omissions of Mitel in performing hereunder.

         s) HCI/MiTAI RunTime License. VAR agrees to enter into the attached
Tri-Party HCI/MiTAI RunTime License Agreement with Mitel and VAR's customer(s)
in instances where VAR is providing to its customer(s) a software application
program that requires Mitel's HCI/MiTAI interface to enable the said program to
be run in conjunction with certain Mitel SX200 and/or SX-2000 PABXs (see a true
copy of such Agreement at SCHEDULE J). VAR agrees to provide an executed copy of
said Agreement at time of order.

         t) Purchases from Third Party. VAR agrees that it will procure all its
new and/or used PRODUCTS solely and directly from Mitel itself. VAR may purchase
used and/or refurbished PRODUCTS from Mitel or from a third-party for resale to
an end-user so long as it abides by the CONDITIONS CONCERNING RESTRICTIONS ON
USE OF SOFTWARE (see SCHEDULE B attached) including the provisions concerning
sub-licensing. Mitel will not unreasonably withhold its consent to transfer
software so long as the transferee agrees to execute and abide by an acceptable
Sub-license and so long as the transferor agrees to comply with Mitel's software
re-licensing policy. In no event, however, may VAR substitute new or unused
software in a used and/or refurbished system without first obtaining Mitel's
prior express written consent and without conspicuously disclosing to the
end-user, in writing, whether or not the system is "like new", used, or
otherwise.

         u) Out-Of-PAR and Web Advertising Policies. In addition to the
information provided in paragraph # 1, above, "Appointment", and paragraph # 3,
above, entitled "Territory", Mitel has further explained the Out-Of-PAR and Web
Advertising Policies on Mitel On-Line. VAR agrees to review such policies and
abide by them in all material aspects.

                                     Page 10                           June 2001
<PAGE>
product) list by giving thirty (30) days prior written notice to VAR. VAR shall
pay the prices set out in the Mitel Caribbean Price List less any applicable
discounts as calculated by SCHEDULE D (VOLUME DISCOUNTS).

         b) VAR agrees to place orders on Mitel by written Purchase Order
("Purchase Order") for all Mitel PRODUCTS to be ordered directly from Mitel
hereunder. Mitel VAR will be offered the option to order product ON-LINE during
the contract year. Irrespective of VAR's Purchase Order, the parties agree to
abide by the Terms and Conditions of Sale as set out in SCHEDULE K, attached
hereto and incorporated by reference herein.

         c) VAR agrees that the SCHEDULE K Terms and Conditions of Sale shall
take precedence over the terms and conditions of the Purchase Order in the event
of a conflict, but that this Agreement shall prevail in the event of a conflict
between it and either the Purchase Order or the SCHEDULE K Terms and Conditions
of Sale. Mitel reserves the right to reject any Purchase Order, in whole or in
part, or to decline to ship an accepted order should it feel insecure in VAR's
ability to pay.

         d) Mitel also reserves the right to impose a minimum purchase amount
per order of Two Hundred Dollars ($200) before taxes and net of all discounts or
reductions.

         e) Mitel shall issue invoices to VAR for Mitel Product shipped to it
hereunder which shall be due and payable thirty (30) days from their date,
subject to paragraph 5(b) hereinabove. VAR shall pay to Mitel the full amount of
the invoice on or before its due date. VAR's obligation to pay and Mitel's right
to receive same shall be absolute and unconditional and not subject to
reduction, set-off or abatement. If, at any time, in Mitel's judgement, VAR's
financial condition and/or payment record makes Mitel feel insecure, Mitel may
deny the further extension of credit, require C.O.D. or otherwise

         f) VAR shall notify Mitel within twenty (20) days from receipt of
invoice of any errors on the invoice. Mitel may grant an extended payment term
of ten (10) business days on the portion of the invoice which is in dispute; the
remainder of the invoice shall be timely paid notwithstanding the extension.

         g) Mitel reserves the right to refuse to accept or process Purchase
Orders from VAR when its account with Mitel is in arrears, and VAR hereby grants
unto Mitel a lien on any Mitel Product being repaired by Mitel until the account
is brought current.

         h) VAR shall pay all taxes, levies or duties now or hereafter imposed
on the importation and/or sales and/or rendering of services with respect to
Mitel Products.

         i) VAR shall have the right, in Mitel's reasonable discretion, to
return unused Mitel Product, if that type of product is still in production,
subject to a reasonable restocking charge at Mitel's then current published rate
(which is currently twenty percent [20%] of list).

         j) VAR recognises and agrees that all prices shall be Ex Works Kanata.
All prices are exclusive of any taxes or charges for insurance or freight, all
of which are the obligations of VAR.

7. SHIPMENT, DELIVERY, TITLE, RISK OF LOSS, INSPECTION, AND CANCELLATION.

         a) Mitel shall use its best efforts to meet any requested delivery date
(to the extent reasonable), but Mitel does not guarantee delivery by that date;
and Mitel shall not be liable to VAR or any third-party (including, but not
limited to, VAR's customer) for any loss or damage, whether direct, special,
collateral, incidental, consequential or otherwise arising from any failure to
ship any Mitel PRODUCTS, or any delay or errors in such shipment regardless of
notice to Mitel of the possibility of such loss or damage. Each shipment shall
be considered an independent and separate transaction, and payment therefore
shall be made accordingly.

         b) Risk of loss for all purposes shall pass to VAR upon delivery of the
Mitel PRODUCTS to VAR Ex Works Kanata. VAR agrees to pursue any claim for
damaged product against the insurer and/or carrier as the case may be. Mitel
shall offer reasonable support of VAR in its pursuit of same. Title to Mitel
PRODUCT shall not pass to VAR until VAR has paid Mitel in full for such product.

         c) Within fifteen (15) days following date of shipment or ten (10) days
following the date of receipt by VAR, whichever expires first, VAR agrees to
inspect the Mitel PRODUCTS ordered and shall promptly notify Mitel, in writing,
of any discrepancies or damages. Failure to so timely notify Mitel shall be
conclusive proof that the Mitel

                                     Page 11                           June 2001
<PAGE>
PRODUCTS were received by VAR as ordered and in good condition.

         d) VAR may cancel any or all portions of a Purchase Order upon a
minimum of thirty (30) days prior written notice to Mitel in advance of the
requested ship date. In the event Mitel ships any or all portions of a Purchase
Order prior to receipt of the cancellation notice, then the purported
cancellation notice shall have no force or effect. No cancellations are allowed
on Purchase Orders within thirty (30) days of requested ship date. In the event
VAR so cancels any or all portions of a Purchase Order, VAR agrees to pay a
cancellation charge equal to twenty percent (20%) of the VARs cost of the
item(s) cancelled, as liquidated damages, which shall constitute the entire
liability of VAR to Mitel with respect to the cancellation.

8. PRODUCT WARRANTIES. Mitel agrees to provide VAR, on all Mitel PRODUCTS
ordered to hereunder, its express limited product warranty as same may be
amended from time to time (Product Warranty is provided to VAR electronically,
see composite SCHEDULE B, attached, for the current version of said Warranty),
subject to the conditions, disclaimers, and limitations of liability stated
therein. VAR accepts said express limited warranty as its sole and exclusive
remedy for defects in Mitel PRODUCT and agrees to the terms and conditions,
disclaimers, and limitations of liability thereof.

9. PRODUCT SPECIFICATION CHANGES. Mitel reserves the right to make changes in
the design or construction of any Mitel PRODUCTS as it deems necessary or
desirable. Mitel will make a reasonable effort to provide prior notification to
VAR of said changes. VAR agrees that Mitel shall incur no obligation to make any
change whatsoever on product previously sold hereunder should it make a
subsequent change nor shall any change create any implications whatsoever that
any part manufactured or furnished without such change is in any way defective.
Mitel agrees to provide reasonable notice of its intent to discontinue
manufacture of a Mitel PRODUCT.

10. SOFTWARE LICENSE. Mitel hereby grants to VAR a non-exclusive license to use
Mitel Software subject to the Terms and Conditions Concerning Use of Mitel
Software. Such is provided electronically, a copy of which is attached hereto as
composite SCHEDULE B. VAR agrees to abide by such terms and conditions. VAR also
agrees to enter into a written sub-license with its customers regarding the use
of Mitel Software, which is at least as protective of Mitel and the Mitel
Software as the license hereby granted. A form of such sub-license approved by
Mitel for use by VAR is attached hereto as SCHEDULE L. VAR recognises and
understands that it receives no license from Mitel should it purchase new or
unused software from a third-party and VAR agrees not to deal in such unlicensed
software. Furthermore, Mitel reserves the right from time to time to distribute
its software via Mitel On-Line and to the extent VAR downloads such for its
business purposes it agrees to abide by the Software License contained herein in
all respects. Likewise, VAR agrees that no additional warranty is offered by
Mitel on software updates or maintenance releases and that such are provided "AS
IS/WHERE IS".

11. PATENT OR TRADEMARK INFRINGEMENT.

         11.1 Mitel's Responsibilities to Defend. Mitel shall indemnify, defend,
and otherwise hold VAR harmless from all cost, loss, damage, and liability
arising from any proceedings brought against VAR to the extent such proceedings
are based on a claim that the Mitel PRODUCTS furnished by Mitel and used within
the scope of this Agreement infringe any Canadian an/or US patent or copyright
or trademark in existence at the commencement of the term of this Agreement.
Mitel shall defend any proceeding alleging such infringement, which is brought
against VAR, and shall pay all costs and expenses incurred and satisfy all
judgements and decrees against VAR in such proceedings, if (i) VAR notifies
Mitel, in writing, within ten (10) business days of the date any such proceeding
becomes known to VAR, (ii) VAR gives Mitel sole control of the defence thereof
and all related settlement negotiations and (iii) VAR provides such assistance,
information, and co-operation to Mitel as is reasonably requested.

         11.2 Mitel's Options. If any of the Mitel PRODUCTS becomes, or in the
opinion of Mitel may become, the subject of such proceedings based upon
infringement or in the event VAR or its customers are enjoined from their use of
Mitel PRODUCTS due to such proceedings based upon infringement, Mitel shall have
the following options:

                  (i) Render the Mitel Products non-infringing and capable of
providing services as intended;

                                     Page 12                           June 2001
<PAGE>
                  (ii) Procure for VAR the right to continue using the Mitel
Products;

                  (iii) Replace the Mitel Products with non-infringing goods
capable of providing services as intended; or

                  (iv) In the event that none of the foregoing options are
technically or economically feasible, remove the Mitel Products and refund the
purchase price thereof less depreciation for use, if any.

         11.3 Exclusions From Liability. Mitel shall have no liability for any
such infringement proceedings, which is based upon:

                  (i) use, operation or combination of the Mitel PRODUCTS with
non-Mitel supplied software, hardware, data or equipment if such infringement
would have been avoided, but for such use, operation or combination;

                  (ii) use of the Mitel PRODUCTS other than in accordance with
Mitel's standard specifications;

                  (iii) modification of the Mitel PRODUCTS by any party other
than Mitel; or

                  (iv) marketing, distribution or use of the Mitel PRODUCTS
other than as authorised herein or other than in a manner for which they were
not designed.

         11.4 Limit of Mitel's Liabilities. The foregoing constitutes the entire
liability of Mitel with respect to infringement of patents, copyrights, and
trademarks, and other intellectual property rights by Mitel PRODUCTS purchased
pursuant to this Agreement. Such liability does not include consequential,
special or punitive damages, such as, without limitation, loss of actual or
prospective profits, or loss of use, all of which are hereby expressly
disclaimed. In no event shall Mitel's liability under this paragraph 11, as a
result of any such proceedings being brought, exceed the amount paid by VAR to
Mitel with regard to the particular transaction, which gives rise to the
liability.

         If any infringement or suspected infringement of the intellectual
property rights of Mitel in relation to the Mitel PRODUCTS or packaging of the
Mitel PRODUCTS by any other company or person in the PAR shall come to the
attention of VAR, VAR shall promptly give notice thereof in writing to Mitel.

12. INDUSTRIAL AND TRADE SECRETS.

         12.1 VAR Acknowledgement. VAR acknowledges that Mitel has developed and
used valuable technical and non-technical information, inventions, copyrights,
trade secrets and other confidential information, and the like (collectively
hereinafter called "Confidential Information") in the development of the Mitel
PRODUCTS. VAR shall use its best efforts to ensure that neither it nor any of
its employees will convert to their own use or to the use of any other party any
Confidential Information owned by Mitel, that is obtained by VAR by reason of
this Agreement or otherwise. VAR agrees to use the same degree of care in
protecting such Confidential Information, as it would use in protecting its own
Confidential Information.

         12.2 VAR's Responsibilities & Limitations. Any Confidential Information
shall be clearly and conspicuously marked by each party as Confidential
Information. VAR shall not be liable for disclosure or use of Confidential
Information marked as proprietary information as provided above which:

                  (i) Is or becomes legally available to the public from a
source other than Mitel before or during the period of this Agreement;

                  (ii) Is released in writing by Mitel;

                  (iii) Is at any time developed by the other party completely
independent of any such disclosure or disclosures.

                                     Page 13                           June 2001
<PAGE>
13. INDEPENDENT CONTRACTORS. VAR's officers, employees or agents shall not be
deemed officers, employees or agents of Mitel, and VAR shall not represent that
its relationship with Mitel is other than that of an independent contractor.
Nothing in this Agreement shall create in either party any right or authority to
incur any obligations on behalf of, or to bind in any respect, the other party.
The parties hereto agree that the arrangement created by this Agreement is not
in the nature of a franchise, partnership, joint venture or agency. VAR agrees
that there is no required payment to become a Mitel VAR and the purchase of any
offering from Mitel is solely to promote and/or for the resale of Mitel
PRODUCTS.

14. TERMINATION.

         14.1 Acknowledgement of Mitel's Marketing Needs. VAR fully understands
the business necessity for Mitel to retain flexibility in Mitel's methods of
selling, marketing, distributing, installing, maintaining, and servicing Mitel
Products. Accordingly, VAR expressly recognises the valid business need for, and
agrees to, the termination provisions set forth below.

         14.2 Termination Provisions. This Agreement may be terminated by Mitel
in its entirety with ten (10) business day's notice in the event:

                  14.2.1 Insolvency or General Assignment for Creditors. VAR
becomes bankrupt or insolvent; the filing by the VAR of a petition in
bankruptcy; the making of an assignment for the benefit of creditors by the VAR;
the appointment of a receiver or trustee for the VAR or for any assets of the
VAR; or the institution by or against the VAR of any other type of insolvency
proceeding under the Bankruptcy Act (Canada), the Company Creditors Arrangements
Act (Canada) or otherwise. The term insolvent shall mean either inability of VAR
to pay its bills as they mature or total liabilities exceed total assets. All
calculations shall be determined in accordance with generally accepted
accounting principles; or

                  14.2.2 Breach Of Representations And Warranties. VAR breaches
any of its material representations and warranties or (except as provided in
14.2.3 below) any other term or obligation of this Agreement and fails to cure
such within thirty (30) days of receiving written notice from Mitel regarding
same in the event the breach is capable of being cured; or

                  14.2.3 Failure To Pay. VAR fails to pay in full all amounts
due Mitel within sixty (60) days of invoice (not including invoices about which
there is a reasonable dispute) except as expressly provided for under the terms
and conditions of this Agreement or if Mitel, in good faith, believes and has
commercially reasonable grounds to believe that the prospect of payment is or is
about to be impaired; or

                  14.2.4 Attempt To Assign Or Transfer. VAR attempts to assign
or transfer its rights or delegate, transfer or subcontract its obligations
under this Agreement to a third party without the prior written consent of
Mitel; or

                  14.2.5 Change Of Business Nature, Ownership Or Control. VAR
notifies Mitel or Mitel becomes aware there is a material change in the nature
or ownership of VAR or its parent or change of control of VAR or its parent
during the term of this Agreement including, but not limited to, any change in
which a competitor of Mitel becomes financially involved in the business of VAR
or any change in which a majority of the stock or substantial portion of the
assets of VAR are transferred in a transaction; or

                  14.2.6 Failure To Achieve Minimum Purchase Requirement (MPR).
VAR fails to meet the Minimum Purchase Requirement of this Agreement during any
annual period of this Agreement or renewal hereof (Mitel also reserves the
right, in its discretion, to redefine the geographic area comprising the VAR's
PAR, when the MPR has not been achieved, instead of terminating the entire
Agreement).

                  14.2.7 VAR Applicability. VAR shall also be entitled to
terminate this Agreement as if it were Mitel in the following sub-paragraphs:
12.2.1, 14.2.2, 14.2.4 and 14.2.5.

         14.3 Termination For Convenience. Either party may, upon the giving of
ninety (90) days prior written notice, terminate this Agreement for its
convenience without incurring any liability to the other except the obligation
to meet all duties arising prior to said termination as well as adhere to those
obligations which by their inherent nature are intended to survive termination.

         14.4 Post Termination Sales. The acceptance by Mitel of any Purchase
Order from VAR or the sale of any Mitel PRODUCTS by Mitel to VAR after the
expiration and/or termination of this

                                     Page 14                           June 2001
<PAGE>
Agreement shall not be construed as a renewal or an extension, or as a waiver of
termination of this Agreement, but in the absence of a new written Agreement,
all such transactions shall be governed by the provisions of this Agreement with
regard to the obligations of VAR to Mitel as stated in Paragraphs 5, 6, 7 and 8
above.

         14.5 Post Termination Rights & Responsibilities. Termination under this
Agreement shall not affect the rights and obligations of the parties concerning
orders accepted by Mitel prior to the effective date of the termination but in
the case of a prior commitment arising as a result of VAR enrolling in the
Software Migration Program, Mitel may elect, in its sole discretion, to return
any monies pre-paid by the VAR and such election and refund shall have the
effect of precluding VAR from receiving any new software loads from Mitel under
such program given the fact that it is no longer an authorized VAR.

         14.6 Limitation Of Post Termination Liabilities. Mitel shall not, by
reason of the termination or non-renewal of the VAR Agreement hereby created, be
liable to VAR for recoupment, compensation, reimbursement or damages on the
account of the loss of prospective profits on anticipated sales, or on account
of expenditures, investments, leases or commitments in connection with the
business or goodwill of VAR. VAR shall likewise have no such liability to Mitel.
Likewise, VAR acknowledges that it will not be substantially affected in its
business by any inability, upon termination or expiry of the Agreement, to
obtain Mitel PRODUCTS beyond the term and scope provided for in the
Post-Termination Support Services delineated in paragraph 14.8 hereinbelow.

         14.7 Obligations After Termination.

                  14.7.1 Payment To Mitel/Survival Of Obligations. Termination
of this Agreement shall not relieve VAR of any obligations to pay Mitel for any
amount payable for transactions prior to or after termination or of the duty to
perform as agreed with regard to Paragraph 5, above, with reference to Mitel
PRODUCTS purchased from and/or sold by VAR.

                  14.7.2 Fulfilment Of Orders. Mitel shall have no obligation to
fill any orders for complete systems placed by VAR after the date of termination
of this Agreement, whether previously quoted or otherwise.

         14.8 Post Termination Support Services. In the event of the
termination, expiration and/or nonrenewal of this Agreement, for reasons other
than VAR's material breach, bankruptcy or insolvency, Mitel shall make available
to VAR, for a period of seven (7) years from the date of such termination,
expiration and/or non-renewal that information and the spare parts (together
herein referred to as "support materials") generally available to Mitel's VARs
which would enable said former VAR to maintain and support its Mitel installed
base as such base existed (site and system) as of the date of termination,
expiration, and/or non-renewal. In no event may the former VAR purchase systems
for such base, however, nor may it purchase new software loads introduced by
Mitel after said termination occurs. These support materials will be made
available at your then current/password protected subsection of the Mitel
Caribbean List Price and in accordance with Mitel's then standard terms and
conditions, but former VAR will not be eligible to take advantage of any
discounts (volume or functional). Likewise, this section does not give VAR a
right to participate in any Mitel Marketing Programs and/or Special Promotions
(e.g., see paragraph 4 above). This provision also does not give VAR a right to
purchase new products (including new software releases) added to Mitel VAR Price
List after the termination, expiration and/or non-renewal of this VAR Agreement.
Termination, expiration and/or non-renewal is also agreed to eliminate the right
of VAR to any benefits it would have been eligible to utilize in any new term or
extension of the contract had cessation of the contract not transpired.
Termination, expiration and/or non-renewal is also agreed to eliminate the right
of VAR to any benefits it would have been eligible to utilize in any new term or
extension of the contract had cessation of the contract not transpired.

other natural catastrophes, or other force majeure events beyond the reasonable

                           CARIBBEAN PRODUCT WARRANTY
                                 FOR MITEL VARS

a. Mitel warrants that its private branch exchange (pbx) customer premises
switches (including its new VOIP version) as well as its voice-mail and
messaging offerings, (hereinafter "PRODUCTS"), except the firmware and software
program components thereof, will, if delivered by VAR to the end-user in
undamaged condition, be free from defects in material and workmanship under
normal use and service for a period of fifteen (15) months from the date of
shipment by Mitel to VAR.

b. Mitel likewise warrants that the software and firmware program components
(including the media itself) of all PRODUCTS, to the extent such are utilized to
provide an operating system or an embedded application ("inside the skins") for
a Mitel pbx or Mitel voice mail or messaging offering, will likewise perform for
fifteen (15) months from the date of shipment from Mitel factory, substantially
in conformity with the Mitel provided technical documentation (functional and
operating specifications) that Mitel publishes regarding same (end-user
reference and operating manuals and guides relating to the program).

c. Mitel likewise warrants that the software and firmware program components of
its PRODUCTS, to the extent such are utilized to provide an external
(peripheral) operating system or an external (peripheral) application for a
Mitel pbx and/or voicemail or messaging offering will perform for a period of
either one hundred twenty (120) days from the date of shipment or ninety (90)
days from the date VAR cuts over the PRODUCT, whichever is sooner. The software
and firmware media for such will nevertheless be warranted for fifteen (15)
months from the date of shipment from the Mitel factory.

d. MITEL DOES NOT, HOWEVER, WARRANT THAT THE FUNCTIONS CONTAINED IN THE SOFTWARE
AND FIRMWARE PROGRAMS AS DESCRIBED IN SUBPARAGRAPHS b) AND c) ABOVE, WILL
SATISFY VAR PARTICULAR PURPOSE AND/OR REQUIREMENTS OR THAT THE OPERATION OF THE
PROGRAM WILL BE UNINTERRUPTED OR ERROR FREE.

e. Notwithstanding anything hereinabove to the contrary, any third-party
developed and licensed software that is not branded by Mitel as a Mitel PRODUCT
or any non-Mitel developed software that is included with a PRODUCT in an
unmodified condition under license from a third-party (e.g., TASKS programs, a
Microsoft program or Novell program) carries just the warranty of the Licensor
which Mitel will pass through to the VAR. SUCH A NON-MITEL PROGRAM IS NOT
SEPARATELY WARRANTED BY MITEL.

f. Mitel shall incur no liability under this warranty and this warranty is
voidable by Mitel (a) if the PRODUCT is used other than under normal use, if the
PRODUCT is not properly serviced and maintained by certified technicians and if
the PRODUCT is not maintained under proper environmental conditions, (b) if the
PRODUCT is subject to abuse, misuse, neglect, flooding, fire, lightning, power
surges or "dirty" power, third-party error or omission, acts of God, damage or
accident, (c) if the PRODUCT is modified or altered (unless expressly authorized
in writing by Mitel), (d) if the PRODUCT is installed or used in combination or
in assembly with products not supplied or authorized by Mitel and/or which are
not compatible with or are of inferior quality, design or performance to Mitel
or Mitel supplied PRODUCTS so as to cause a diminution or degradation in
functionality, (e) if there is a failure to follow specific restrictions in
operating instructions or (f) if payment for PRODUCT has not been timely made.

g. The sole obligation of Mitel and the exclusive remedy and recourse of VAR
under this warranty, or any other legal obligation, with respect to PRODUCT,
including hardware, firmware, and software media, is for Mitel, at its election,
to either repair and/or replace the allegedly defective PRODUCT or component(s)
thereof and return (prepaid) same (if necessary), or grant a reimbursement
credit with respect to the PRODUCT or component. With regard to a software
program design defect, however, to the extent it prevents the program from
providing specified functionality and/or operating as intended by Mitel, is
service affecting, and prevents beneficial use of the product, Mitel does
undertake to use its best efforts to devise a suitable corrective solution to
the problem within a reasonable period of time; should said action, however, not
substantially resolve the problem, then Mitel reserves the right to incorporate
such solution in a new release ("stream") of software. The above,

                                     Page 20                           June 2001
<PAGE>
with regard to a software design defect, likewise, constitutes the sole
obligation of Mitel and exclusive remedy of VAR hereunder with respect to
PRODUCT.

h. The responsibility of Mitel to honor the express limited warranty stated
above also shall be predicated on receiving timely written notice of the alleged
defect(s) with as much specificity as is known within thirty (30) calendar days
of the malfunction or by the expiration of the warranty period (plus thirty [30]
calendar days), whichever occurs first. Mitel shall further have the right to
inspect and test the PRODUCT to determine, in its reasonable discretion, if the
alleged malfunction is actually due to defects in material or workmanship caused
by Mitel. Unless waived by Mitel, VAR agrees to return (prepaid) the allegedly
defective PRODUCT or component to Mitel for inspection and/or testing, and, if
appropriate, for repair and/or replacement.

i. THE ABOVE EXPRESS LIMITED WARRANTY IS IN LIEU OF ALL OTHER CONDITIONS AND
WARRANTIES, EXPRESS OR IMPLIED, FROM MITEL (INCLUDING ITS PARENT) AND THERE ARE
NO OTHER WARRANTIES WHICH EXTEND BEYOND THE FACE OF THIS WARRANTY. ALL OTHER
WARRANTIES, INCLUDING THE IMPLIED WARRANTY OF MERCHANTABILITY AND THE IMPLIED
WARRANTY OF FITNESS FOR A PARTICULAR PURPOSE RELATING TO USE OR PERFORMANCE OF
THE PRODUCT, INCLUDING ITS PARTS, ARE HEREBY EXCLUDED AND DISCLAIMED.

j. IN NO EVENT SHALL MITEL (INCLUDING ITS PARENT) UNDER ANY CIRCUMSTANCES, BE
LIABLE FOR NOR SHALL VAR (DIRECTLY OR INDIRECTLY) BE ENTITLED TO ANY SPECIAL,
CONSEQUENTIAL, INCIDENTAL, INDIRECT, PUNITIVE OR EXEMPLARY DAMAGES AS A RESULT
OF THE SALE OR LEASE OF PRODUCT, INCLUDING BUT NOT LIMITED TO FAILURE TO TIMELY
DELIVER THE PRODUCT OR FAILURE OF PRODUCT TO ACHIEVE CERTAIN FUNCTIONALITY, OR
ARISING OUT OF THE USE OR INABILITY TO USE THE PRODUCT, IN WHOLE OR IN PART AND
INCLUDING BUT NOT LIMITED TO LOSS OF PROFIT, LOSS OF USE, DAMAGE TO BUSINESS OR
DAMAGE TO BUSINESS RELATIONS. MITEL SHALL NOT BE LIABLE FOR PERSONAL INJURY OR
PROPERTY DAMAGE UNLESS CAUSED SOLELY BY MITEL'S NEGLIGENCE.

Mitel Networks' VOIP Readiness Services Package includes a combination of
pre-sales support, coupled with network assessment and design services, to help
assure a properly designed, configured and implemented solution for single-site,
non-networked March Networks 32001CP sales.

Pre-Sales Support - Your Mitel Account Executive and Sales Engineer will work
closely with you to help assure that all special VOIP considerations are
reviewed and to configure the appropriate March Networks IP solution.

Network Assessment - Our VOIP experts will assess the suitability of the
existing LAN infrastructure to support the proposed March Networks IP solution.
Included with this assessment is an engineering-level recommendation outlining
the network upgrades that may be required to assure relatively seamless VOIP
integration.

Network Design - Building on the Network Assessment, our next step is to define
the network structure that will fit your proposed March Networks IP solution. We
will provide written recommendations that outline the placement and
specifications of all network elements.

                             VOLUME BASED DISCOUNTS

VAR's Discount for the Mitel PRODUCTS listed in the Mitel Caribbean Price List
will be pre-determined by the VAR's historical Mitel sales volume production as
recorded by Mitel for the previous twelve (12) months as it relates to the
Volume Discount Table illustrated below. This calculation will equate to VAR's
"Annual Sales Discount Objective". If VAR has less than one (1) year of sales
history with Mitel, the "Annual Sales Discount Objective" will be based on
qualifying sales (in Mitel's discretion) of the telecommunications products of
others. If VAR is new and has no sales history, the "Annual Sales Discount
Objective" will be based on reasonable sales projections as agreed upon by Mitel
and VAR. VAR's Discount (herein called "Assigned Discount") for the agreed
Annual Sales Discount Objective will initially be subject to increase or
decrease as stated below.

Mitel reserves the right on a quarterly basis to review the Assigned Discount
based on the results of a review of the VAR's Product Purchases. If Mitel
determines, in its discretion, that based upon the prior quarter's performance
of the VAR that the VAR will not achieve its Annual Sales Discount objective,
Mitel shall adjust the Assigned Discount in accordance with the Volume Discount
Table which replacement Assigned Discount shall apply for the succeeding Quarter
and so on. Mitel shall, likewise, increase the discount on a quarterly basis to
the extent justified. To the extent VAR fails to meet or exceed its discount
objective for the preceding quarter, Mitel also reserves the right, in making
the downward adjustment for the ensuing quarter, to include the unearned
discount received the previous quarter and/or quarters in the calculation in
such a way as to recapture the shortfall.

design, project management, wireless RF site survey and advanced engineering
services.

testing.
