All capitalized terms used herein shall have the
meaning ascribed to them in the Purchase Agreement unless otherwise defined

defined in the body of this Agreement shall have the respective meanings given
to such terms in Exhibit A attached hereto.

 

Buyer and Seller wish to make arrangements for the
transition of the Business from Seller to Buyer following the Closing of the
transactions contemplated by the Purchase Agreement, pursuant to this
Agreement.

 

NOW, THEREFORE, in consideration of the promises and
mutual covenants set forth in the Purchase Agreement and herein, and other good
and valuable consideration, and contingent upon the Closing, the parties hereby
agree as follows:

 

1.                   Transition of
the HM5600 Business.  Pursuant to
the Purchase Agreement, Seller has retained all obligations under the HM5000
Contracts and Buyer has acquired all rights under the HM5000 Contracts.  Therefore, pursuant to the Purchase,
Agreement, with respect to the HM5000 Customers, Seller has retained all
liability and responsibility under the HM5000 Contracts and Buyer has acquired
all rights under the HM5000 Contracts, including the sole right to enforce the
term thereof and, subject to the limitations set forth herein, to modify the
terms thereof (including the rates thereunder) and terminate the contract, in
each case in accordance with the terms of thereof.  However, as between Seller and Buyer, certain rights and
responsibilities with respect to the HM5000 Customers shall be as set forth in
this Section 1.

 

1.1                                 Provision
of HM5000 Airtime Services. 
Pursuant to the HM5000 Contracts, Seller shall remain obligated to the
HM5000 Customers to provide the Enhanced Services (as defined in the HM5000
Contracts) and the Enhanced Cellular Roaming (as defined in the HM5000
Contracts) during the respective terms of such contracts and in accordance with
the terms and conditions thereof (collectively, the “HM5000 Airtime Services”).
With respect to the Term HM5000 Customers, Seller hereby agrees with and
covenants to Buyer that Seller shall, unless and until otherwise directed by
Buyer, provide HM5000 Airtime Services to each such Term HM5000 Customer
pursuant to the terms of its HM5000 Contract until the later of (i) the
expiration of the fixed term of its HM5000 Contract and (ii) September 30,
2003, or such later date as may be mutually agreed by the parties. With respect
to the Month-to-Month HM5000 Customers, Seller hereby agrees with and covenants
to Buyer that Seller shall, unless and until otherwise directed by Buyer,
provide HM5000 Airtime Services to each such Month-to-Month HM5000 Customer
pursuant to the terms of its HM5000 Contract until September 30, 2003, or

 

 

such later date as may be
mutually agreed by the parties.  Each
HM5000 Customer shall be permitted to renew its HM5000 Contract upon expiration
in accordance with the renewal terms thereof and, in the event of any such
renewal (whether automatic or otherwise), such expiration shall not constitute
a termination of such contract that would relieve Seller of its obligation to
Buyer to provide HM5000 Airtime Services to such HM5000 Customer pursuant to
this Section 1.1; provided, however, that no HM5000 Customer may
renew its HM5000 Contract for a term that extends beyond September 30,2003,
unless otherwise mutually agreed by the parties.  Upon instruction from Buyer, and provided that such suspension
would not result in Seller’s breach of the applicable HM5000 Contract, Seller
shall permanently cease or temporarily suspend providing HM5000 Airtime
Services to any HM5000 Customer. 
Because, subject to the limitations set forth above, all rights under
the HM5000 Contracts have been assigned to Buyer pursuant to the Purchase
Agreement, subject to Section 4.l(c), Seller shall have no right to terminate
or modify the HM5000 Contracts or to discontinue provision of the HM5000
Airtime Services, except as directed by Buyer in accordance with the foregoing.

 

1.2                                 Consideration
for Provision of HM5000 Airtime Services. 
In exchange for Seller’s promise to Buyer to provide the HM5000 Airtime
Services to the HM5000 Customers in accordance with Section 1.1, for so long as
Seller provides such HM5000 Airtime Services pursuant to Section 1.1, except as
otherwise provided in paragraph (g), Buyer hereby agrees to pay Seller Seller’s
actual costs of providing the HM5000 Airtime Services to the extent set forth
below:

 

(a)  Third
Party Cellular Services.

 

(i)                                     Seller
is charged for the HM5000 Airtime Services by Seller’s cellular carriers (the “Cellular
Carriers”), who charge Seller per minute of HM5000 Airtime Services. The
per minute rates for each Cellular Carrier that Seller uses to provide the
HM5000 Airtime Services are attached hereto, listed by carrier, as Exhibit

warrants to Purchaser that the rates and information set forth on Exhibit
B-1 are true, correct and complete as of the date hereof.  Seller shall charge Buyer for the HM5000
Airtime Services invoiced to Seller by the Cellular Carriers at the applicable
rate Seller is charged for such HM5000 Airtime Services, as set forth in Exhibit
B-1.  Seller may amend Exhibit
B-1 only upon thirty (30) days prior written notice to Buyer and only to
the extent necessary to reflect actual rate increases imposed on Seller by the
Cellular Carriers and to reflect changes in Cellular Carriers.

 

(ii)                                  Seller
shall use commercially reasonable efforts (and in no event less than the same
level of efforts that Seller used in such situations prior to Closing) (A) to
audit the charges made to it by the Cellular Carriers for the HM5000 Airtime
Services in order to verify that Seller was charged at the correct rates and
(B) in the event such audit reveals an overcharge by such Cellular Carriers, to
seek a refund.  Seller shall inform
Buyer of any such overcharge, keep Buyer apprised of efforts to obtain a refund
of such overcharge, and promptly remit any such refund received to Buyer.

for the Administrative Carrier Services used by Seller for the provision of the
HM5000 Airtime Services and invoiced to Seller by Cingular Wireless at the rate

and Toll-Free Services used by Seller for the provision of the HM5000 Airtime
Services and invoiced to Seller by its long-distance/toll-free service
providers at the applicable rate Seller is charged for such Long Distance and
Toll-Free Services as set forth in Exhibit B-2.  Seller may amend Exhibit B-2 only
upon thirty (30) days prior written notice to Buyer and only to the extent
necessary to reflect actual rate increases imposed on Seller by its

Seller ceases to provide HM5000 Airtime Services hereunder) shall be prorated
accordingly.  In exchange for the
foregoing payment, Seller agrees to maintain and technically support the NSC
with same level of care as Seller used to perform these activities prior to
Closing, but in no event less than a commercially reasonable standard of care.  With respect to the Cellemetry Gateway, the
foregoing obligation to provide maintenance and technical support shall
continue only until Buyer has implemented a replacement of the Cellemetry
Gateway in accordance with Section 2.4.

passed through to Buyer
pursuant to such invoice to verify that Seller has charged Buyer in accordance
with this Section 1.  For a period of
one year after Buyer receives my invoice under this paragraph (f), Seller shall
retain all documentation (including the bills Seller received from the
applicable service provider and the documentation recording the usage of the
HM5000 Airtime Services by the HM5000 Customers) necessary for Buyer to verify
the accuracy of the charges passed through to Buyer pursuant to such invoice
and Seller shall make such documentation available to Buyer in the event Buyer
exercises its audit right.  Seller shall
promptly remit to Buyer the amount of any overcharge revealed as a result of
any Buyer audit; provided, that Buyer shall provide Seller with the
documentation substantiating any such overcharge.  To the extent any Buyer audit reveals that Seller has overcharged
Buyer by greater than five percent (5%), Seller shall remit to Buyer the amount
of such overcharge plus twenty percent (20%) of such amount.

 

(g)  Direct
Payment to Third-Party Providers. 
Notwithstanding any other provision of this Section 1.2, in the event
that Seller is more than thirty (30) days past due on the payments it awes to
my third party provider of the HM5000 Airtime Services, the TSI Services, the
Administrative Carrier Services or the Long Distance or the Toll-Free Services,
Buyer may, at its option, choose to pay the mounts it would otherwise pay to
Seller pursuant to this Section 1.2 directly to the applicable third-party
provider instead.  In such case, Buyer
shall make clear to the third-party provider that it is making such payments on
Seller’s behalf and shall provide evidence to Seller that it has made such
payments.

and (d) shall be reduced accordingly, as further described in Exhibit C.

 

(b)  Seller
shall notify a Buyer Customer Care manager immediately in the event of any
unscheduled interruption of the Network Service and shall keep Customer Care

Service.

and pursuant to the terms and conditions of, the HM5000 Contracts.  Buyer shall indemnify, defend, protect and
hold harmless the Seller Indemnified Parties from, against and in respect of
any and all Damages suffered, sustained, incurred or paid by any of the Seller

shall be to foster and encourage a future business relationship between Buyer
and such Major HM5000 Customers and the conduct of the meeting, by both
parties, shall be consistent with such purpose.  “Major HM5000 Customers” shall mean the top ten (10)
HM5000 Customers as measured by HM5000 mobile unit installation base as of the
Closing.

 

1.6                                 Indemnification.  Except as otherwise provided in this

intend that such terms shall refer to the most closely corresponding terms and

each case as required for Seller to perform the Cellemetry Billing Services in
accordance with this Agreement.

 

(c)  Consideration
for Billing Services.  In exchange

shall appear in place of Seller’s payment information on all such invoices.

 

(e)  Service
Level Guarantees.  As further
described in Exhibit D, Seller shall guarantee Buyer that it shall

that Seller does not meet such service levels, the amounts paid by Buyer to
Seller pursuant to Section 3.3(c) shall be reduced accordingly, as further

(f)  Notification
to Customers.  Within ten (10)

Business (including the HM5000 Customers) that the rights under the applicable
contracts with Seller have been assigned to Buyer, that payment in respect of
all invoices under such contracts that are received by such customer after the

the Business shall be made to Buyer (but may be still be made by calling the
same toll-free number as set forth in their contract or writing to the same
address as set forth in their contract). 
In addition, such notices shall provide Buyer’s email contact

Seller shall provide a draft version of the foregoing notice to Buyer for
Buyer’s review and comment.  Seller
shall incorporate all suggestions and changes reasonably requested by Buyer to
such notice.  To the extent that Buyer
takes longer than two (2) business days either to provide suggestions and

to the customers shall be extended.

 

(g)  Taxes

Seller shall be responsible for remitting to the appropriate local,
state, federal or foreign government or governmental agency (“Taxing

Customers pursuant to Section 3.3(a) hereof (collectively, the “HM5000 Taxes”).  Seller shall invoice Buyer on a monthly
basis for any HM5000 Taxes paid by Seller. 
Upon receipt of an invoice and supporting documentation showing the
calculation of the HM5000 Taxes and evidencing that such Taxes have been
properly and timely paid to the appropriate Taxing Authorities, Buyer shall
reimburse Seller within fifteen (15) business days for the amount of such
HM5000 Taxes.  Notwithstanding the
foregoing, Buyer shall not be responsible for reimbursing Seller for any Taxes

(ii) any assertion,
allegation or claim, of whatever nature, by any Taxing Authority that any Buyer
Indemnified Party is liable for payment of or was required to remit any HM5000
Taxes, but in no event shall such indemnification exceed fifteen million
dollars ($15,000,000).  Seller shall
provide such Buyer Indemnified Party with such assistance as may be reasonably
requested in connection the with any claim for which Seller may have
indemnification responsibility pursuant to the preceding sentence.  In its performance of the HM5000 Billing
Services, Seller shall accommodate Buyer’s requests regarding the invoicing and
remittance of Taxes to the extent that Buyer has been advised by its outside
legal counsel or its outside accountants that Buyer is legally obligated to
collect from customers and remit to any Taxing Authority any such Tax.

 

(h)   Taxes
with Respect to TrackWare and 20/20V Business.  Buyer shall be responsible for remitting to the appropriate
Taxing Authority all Taxes owed in respect of the amounts billed to TrackWare
Product Line and 20/20V Product Line customers with respect to the period after
the Closing.  In addition, Buyer shall
have sole control over what Taxes are invoiced to such customers and, in its
performance of the Cellemetry Billing Services, Seller shall follow Buyer’s
instruction in the preparation of the invoice, including with respect to
invoicing of Taxes.

 

3.4                                 Buyer
Responsible for Collection Efforts. 
Although Seller will send out all invoices to customers pursuant to
performance of the Billing Services, Buyer shall control all collection and
posting of payment.  Buyer shall send
Seller a file containing the posting records of all moneys received in payment
of the invoices sent by Seller in the performance of the Billing Services
within one business day after posting in Buyer’s billing system.  Such file shall be in a format reasonably
specified by Seller, which format may be changed by Seller from time to time
upon reasonable advance notice to Buyer. 
All post office boxes listed as the address for payment in the customer
contracts of the Business acquired by Buyer pursuant to the Purchase Agreement
(including the HM5000 Contracts) (“Acquired Post Office Boxes”) are an
Acquired Asset and Seller shall take all action necessary to transfer ownership
of such post office boxes and keys to Buyer promptly after Closing.

 

3.5                                 Customer
Billing Inquiries.  Because Seller’s
performance of the Billing Services for Buyer will result in Seller employees
who have the knowledge and access to information to answer the billing inquires
of Buyer’s customers, Seller shall insure that personnel familiar with the
Billing Services and qualified to answer such inquiries will be available to
Buyer’s Customer Care representatives to answer such inquires during regular
business hours.

 

4.                   Accounts
Receivable and Payable.

 

4.1                                 Accounts
Receivable: General.

 

(a)  Pursuant
to the Purchase Agreement, it is generally understood that all receivables (i)
of the Business for activities on and before the Closing and (ii) in respect of
the provision of HM5000 Airtime Services on and before the Closing (“Pre-Closing
Receivables”) are the property of Seller, and that all receivables (x) of
the Business for activities after the Closing, and (y) in respect of the
provision of HM5000 Airtime Services after the Closing (“Post-Closing
Receivables”) are the property of Buyer. 
The parties shall cooperate to insure

 

10

 

that Buyer receives
payment in respect of Post-Closing Receivables and Seller receives payment in
respect of Pre-Closing Receivables. 
However, to the extent that Buyer receives payment in respect of a
Pre-Closing Receivable it shall transfer such payment promptly to Seller and to
the extent that Seller receives payment in respect of a Post-Closing
Receivable, it shall transfer such payment promptly to Buyer.  For example, if a customer makes a payment
for the billing cycle in which Closing occurs, and such amount was billed in
arrears, Buyer shall remit the pre-Closing portion of such payment to Seller
and if such amount was billed in advance, Seller shall remit the post-Closing
portion of such payment to Buyer.  In
the event that (A) a payment is received by either party within the forty-five
(45) day period following Closing that is not designated by the payor as being
in respect of either a Pre-Closing Receivable or Post-Closing Receivable, (B) the
designation of such payment as a Pre-Closing or Post-Closing Receivable is not
otherwise addressed by Section 4.2, and (C) such payor owes money with respect
to at least one Pre-Closing Receivable and at least one Post-Closing
Receivable, Seller shall be entitled to such payment to the extent required to
cover all Recent Receivables owed by such payor and Buyer shall be entitled to
the balance thereof.  In the event that
(A) a payment is received by either party after the forty-five (45) day period
following Closing that is not designated by the payor as being in respect of
either a Pre-Closing Receivable or Post-Closing Receivable, (B) the designation
of such payment as a Pre-Closing or Post-Closing Receivable is not otherwise
addressed by Section 4.2, and (C) such payor owes money with respect to at
least one Pre-Closing Receivable and at least one Post-Closing Receivable,
Buyer shall be entitled to such payment to the extent required to cover all
Post-Closing Receivables owed by such payor and Seller shall be entitled to the
balance thereof to the extent required to cover all Recent Receivables owed by
such payor.

 

(b)  With
respect to Pre-Closing Receivables that, as of the Closing, have been
outstanding for more than ninety (90) days, Seller, agrees with and covenants
to Buyer that Seller shall not seek payment from or legal recourse against
customers with respect to such receivables or contact customers with respect to
such receivables.  For the avoidance of
doubt, to the extent that, after Closing, Buyer receives payment that is
designated by payor in respect of any Pre-Closing Receivable, including any
receivable that was outstanding for more than ninety (90) days as of the
Closing, Buyer shall promptly transfer such payment to Seller in accordance with
paragraph (a).

 

(c)  With
respect to Pre-Closing Receivables that, as of the Closing, have been
outstanding for ninety (90) days or less (the “Recent Receivables”),
during the sixty (60) day period following the Closing, Seller may contact
customers to seek payment of such Recent Receivables in the ordinary course,
but may not take or threaten to take legal action against such customers, or
terminate or threaten to terminate such customers’ HM5000 Airtime Services or
Cellemetry Services, as the case may be. 
After the first sixty (60) days following the Closing, in the event that
(A) a Recent Receivable is more than 90 days’ past due and (B) Seller has made
at least one post-Closing request for payment of such Recent Receivable from
such customer and customer either has not responded to such request or has not
provided any valid reason to Seller for non-payment in response to such
request, Seller shall be entitled to request in writing consent from Buyer for
Seller to terminate such customer’s HM5000 Airtime Services or request that
Buyer terminate such customer’s Cellemetry Services, as the case may be.  Buyer shall have thirty (30) days from the
time of such request to attempt to resolve the situation with the customer.  If, by the end of such thirty-day period,
Buyer has not (i) obtained payment of any

 

11

 

Pre-Closing Receivable
from such customer or caused such customer to make payment of any Pre-Closing
Receivable to Seller, (ii) entered into a payment plan with such customer with
respect to the Recent Receivable that has been approved by Seller or (iii)
discovered a valid reason that such customer has not paid the Recent
Receivable, Buyer shall terminate, or shall authorize Seller to terminate, as
applicable, such customer’s services if requested by Seller in writing and, in
addition to the foregoing right to terminate service, Seller shall then be free
to pursue legal recourse against such customer with respect to such Recent
Receivable.

General.  Within one hundred and
eighty (180) days after Closing, the parties shall have developed a complete
plan for the smooth transition from Seller systems to Buyer systems, including
a time frame for completing such transition. 
In general, Seller agrees to use all reasonable efforts to assist Buyer
in transitioning from Seller’s system to Buyer’s systems.  For example, Seller will continue to
maintain and support all Seller systems required (i) for Buyer to continue to
operate the Business in substantially the same manner as Seller operated the
Business prior to Closing during the agreed-upon transition period and (ii) for
Seller to perform its obligations under this Agreement.  The foregoing maintenance, activities shall

Buyer to operate the Business in substantially the same manner as Seller
operated the Business prior to Closing. 
In addition, Seller shall allow Buyer to keep certain Buyer equipment in
Seller’s data center, and shall allow Buyer access to the data center in order
for Buyer to maintain such equipment. 
Seller shall cooperate with Buyer to make all arrangements reasonably
necessary, as determined by Buyer, to facilitate the prompt integration of the
systems Buyer has acquired from Seller pursuant to the Purchase Agreement with

Seller shall, allow Buyer employees to continue using Seller network,
phone system and automated call distribution (ACD) system during the Lease
Transition Period.  The New Buyer
Employees will retain the same phones and phone numbers after Closing as they
had before Closing.  Seller will charge
Buyer a pro-rated portion of Seller’s monthly operation costs for its network,
phone system and ACD system based on the number of New Buyer Employees using
such systems as of the Closing versus the total number of persons using such
systems as of the Closing.  The
foregoing operation costs are itemized in Schedule 9.2(a) and shall not
be modified without the consent of both parties.  Buyer may terminate any or all of the network, phone system or
ACD system sharing arrangements upon thirty (30) days notice to Seller, in
which event Buyer shall no longer pay any portion of the applicable operation
costs.

 

(b)  General
Office Systems.  Buyer employees
working in the Office Space or the Warehouse Space shall retain access to
Seller’s general office software (e.g., e-mail, print functionality, word

established connectivity between the Office Space and Warehouse Space and
Buyer’s network and has provided Buyer employees located at the Office Space
and Warehouse Space access to the equivalent Buyer office software on Buyer’s
network.  Buyer shall use

 

15

 

commercially reasonable
efforts to establish such connectivity and provide such access in an
expeditious manner.

 

(c)  SCOPUS.  Seller shall obtain consent to assign twenty
(20) SCOPUS licenses to Buyer no later than ten (10) business days after
Closing.

 

(i)                                     In
the event that Seller obtains such SCOPUS licenses within such period, then
within thirty (30) days after Closing, Seller shall segregate the SCOPUS
database into two instances and transfer one to Buyer.  Prior to such transfer, Seller may purge the
Buyer’s instance of the SCOPUS database of any information not related to or
reasonably necessary for the conduct of the Business by Buyer in the
substantially the same manner as conducted by Seller prior to Closing.  During the period prior to which the
database instance is transferred to Buyer in accordance with the foregoing,
Seller shall make available its instance of the database to Buyer to the extent
reasonably necessary for the conduct of the Business by Buyer in the
substantially the same manner as conducted by Seller prior to Closing.

 

(ii)                                  In
the event that Seller does not obtain such SCOPUS licenses within such period,
then Buyer shall be permitted to continue to use twenty (20) of Seller’s SCOPUS
seats and have full access to the SCOPUS database until all current and
historical customer data contained in the SCOPUS database, current through the
date of migration, have been migrated to Buyer’s customer, service database, provided,
that Seller shall cooperate with Buyer to perform the foregoing migration in
accordance with the reasonable specifications provided by Buyer and provided,
further, that such migration shall be completed no later than one
hundred and twenty (120) days after the date on which Buyer has established
connectivity between the Office Space and Buyer’s network and has provided
Buyer employees located at the Office Space access to the Buyer customer
service software on Buyer’s network. 
The parties will use commercially reasonable efforts to establish such
connectivity expeditiously.

 

(d)  Provisioning
and Activation.  Provisioning and
activation of the Units shall be initiated by Buyer via SCOPUS.  However, to the extent that implementation
of such provisioning and activation functions involves systems other than
SCOPUS, Seller shall support such provisioning and activation activities: (i)
for the HM5000 mobile units, for so long as Seller provides the HM5000 Airtime
Services hereunder and (ii) for the TrackWare Product Line and 20/20V Product
Line, until the replacement of the Cellemetry Gateway pursuant to 2.4.  Notwithstanding the foregoing, in the event
that the twenty (20) SCOPUS licenses are not assigned to Buyer in accordance
with paragraph (c) above, after Buyer has transitioned off the SCOPUS system
pursuant to clause (ii) of paragraph (c) above, Seller shall support all
provisioning and activation activities: (i) for the HM5000 mobile units, for so
long as Seller provides the HM5000 Airtime Services hereunder and (ii) for the
TrackWare Product Line and 20/20V Product Line, until the end of the Lease
Transition Period or such earlier time as Buyer has implemented the capability
to perform such activities itself.

 

(e)  Billing.

 

(i)                                     For
so long as Seller performs any Billing Services hereunder, Seller shall send
Buyer a file containing the invoice records of all customers invoiced by Seller
pursuant to its performance of the Billing Services within one business day of
the billing run

 

16

 

completion.  Such file shall be in a format reasonably
specified by Buyer, which format may be changed by Buyer from time to time upon
reasonable advance notice to Seller. 
Such file shall be transmitted to Buyer for manual input by Buyer into
Buyer’s billing systems until connectivity is established between Seller’s
billing systems (including, for so long as Seller performs the Cellemetry
Billing Services, the Cellemetry Billing System) and Buyer’s billing system,
after which Seller shall download the file to Buyer’s billing system on an
automated basis.  The parties will use
commercially reasonable efforts to establish such connectivity expeditiously.

 

(ii)                                  If
Seller has not already done so prior to Closing, no later than five (5)
business days after Closing, Seller shall provide Buyer with a file containing
all customer billing records of the Business which shall contain at least the
following information with respect to each customer: (i) such customer’s name,
billing address, customer number, and billing cycle information; (ii) for
HM5000 Customers, the activation fee and unit purchase prices applicable to
such customer; (iii) for 20/20V and TrackWare customers, the activation fee,
unit purchase prices and website subscription fee applicable to such to
customer; (iv) for Platinum Service customers, all fees applicable to such
customer pursuant to its Information Management Services Agreement.  Such file shall be in a format reasonably
specified by Buyer.  To the extent that
Buyer has not provided Seller with the format for such file, Seller’s
obligation to provide the records shall be extended.

 

(f)  Inventory
Management Stems.  If Seller has not
already done so prior to Closing, no later than three (3) business days after
Closing, Seller shall provide Buyer with a file containing the inventory
records with respect to all Inventory acquired by Buyer pursuant to the

such file, Seller’s obligation to provide the records shall be extended.

 

10.            Manner of Performance.
 Each party shall provide the
services to be provided by it hereunder with the same degree of care, skill and
diligence with which it performs similar services for itself or others, but in
no event less than a commercially reasonable degree of care and, in the ease of
Seller, in no event less than the degree of care it used to perform such
services for itself prior to the Closing.

FIRST AMENDMENT TO
TRANSITION SERVICES AGREEMENT

 

THIS FIRST AMENDMENT TO TRANSITION SERVICES AGREEMENT
(“First Amendment”) is made and entered into this 8th day of
July, 2003, by and between Aether Systems, Inc., a Delaware corporation
(the “Buyer”), and Minorplanet Systems USA, Inc. formerly @Track
Communications, Inc., a Delaware corporation (the “Seller”) and is
effective July 8, 2003.   This Amendment
shall not be applied retroactively.

 

RECITALS

 

WHEREAS, Buyer and Seller have entered into that
certain Asset Purchase Agreement dated as of March 15, 2002 (the “Purchase
Agreement”), whereby Seller has conveyed and Buyer has acquired the
Acquired Assets used by Seller with respect to the Business

 

WHEREAS, Buyer and Seller entered into that certain
Transition Services Agreement dated as of March 15, 2002 (the “Transition
Agreement”);

 

WHEREAS, Buyer and Seller wish to amend the Transition
Agreement as more specifically set forth below herein:

 

NOW, THEREFORE, in consideration of the promises and
mutual covenants set forth herein, and other good and valuable consideration,
the parties hereby agree as follows:

 

1.               Section
1.1 of the Transition Agreement is deleted in its entirety and replaced with
the following new Section 1.1:

 

“1.1                           Provision
of HM5000 Airtime Services.  
Pursuant to the HM5000 Contracts, Seller shall remain obligated to the
HM5000 Customers to provide the Enhanced Services (as defined in the HM5000
Contracts) and the Enhanced Cellular Roaming (as defined in the HM5000
Contracts) during the respective terms of such contracts and in accordance with
the terms and conditions thereof (collectively, the “HM5000 Airtime
Services”).  With respect to the Term
HM5000 Customers, Seller hereby agrees with and covenants to Buyer that Seller
shall, unless and until otherwise directed by Buyer, provide HM5000 Airtime
Services to each such Term HM5000 Customer pursuant to the terms of its HM5000
Contract until the later of (i) the expiration of the fixed term of its HM5000
Contract and (ii) January 30, 2005, or such later date as may be mutually
agreed by the parties.  With respect to
the Month-to-Month HM5000 Customers, Seller hereby agrees with and covenants to
Buyer that Seller shall, unless and until otherwise directed by Buyer, provide
HM5000 Airtime Services to each such Month-to-Month HM5000 Customer pursuant to
the terms of its HM5000 Contract until January 30, 2005, or such later date as
may be mutually agreed by the parties. 
Each HM5000 Customer shall be permitted to renew its HM5000 Contract
upon expiration in accordance with the renewal terms thereof and, in the event
of any such renewal (whether automatic or otherwise), such expiration shall not
constitute a termination of such contract that would relieve Seller of its
obligation to Buyer to provide HM5000 Airtime Services to such HM5000 Customer
pursuant to this Section 1.1; provided, however, that no HM5000
Customer may renew its HM5000 Contract for a term that extends beyond January
30, 2005, unless otherwise mutually agreed by the parties.  Upon instruction from Buyer, and provided

 

 

that such suspension would not result in Seller’s
breach of the applicable HM5000 Contract, Seller shall permanently cease or
temporarily suspend providing HM5000 Airtime Services to any HM5000
Customer.   Because, subject to the
limitations set forth above, all rights under the HM5000 Contracts have been
assigned to Buyer pursuant to the Purchase Agreement, subject to Section
4.l(c), Seller shall have no right to terminate or modify the HM5000 Contracts
or to discontinue provision of the HM5000 Airtime Services, except as directed
by Buyer in accordance with the foregoing.”

 

2.               The
first full sentence in Section 1.2 (e) of the Transition Agreement is deleted
in its entirety and replaced with the following:

 

[*]

 

3.               Section
6.2 of the Transition Agreement and Exhibit F to the Transition Agreement shall
be deleted in their entirety.

 

4.               Section
1.9 of Exhibit C to the Transition Agreement shall be deleted in its entirety
and replaced with the following new Section 1.9:

 

“1.9 “Network Downtime Credits” shall mean
credits issued by Seller to Buyer against the charges made by Seller to Buyer
pursuant to Sections 1.2(e) of the Agreement, pursuant to which Buyer
reimburses Seller for certain of its costs of providing the HM5000 Airtime
Services, as per the terms and conditions of Section 3 below.”

 

5.               The
second and third full sentences in Section 2.1 of Exhibit C to the Transition
Agreement shall be deleted in their entirety.

 

6.               Section
3.1 of Exhibit C to the Transition Agreement shall be deleted in its entirety
and replaced with the following new Section 3.1:

 

“Buyer shall receive a credit against the monthly
charges made by Seller to Buyer pursuant to Section 1.2(e) of the Agreement,
based upon “Network Availability Percentage” calculated as follows:”

 

100% – Network Downtime Percentage = Network
Availability Percentage

 

7.               Section
3.3 of Exhibit C to the Transition Agreement shall be deleted in its entirety
and replaced with the following new Section 3.3:

 

“3.3                           Based
on the Network Availability Percentage, the following Network Downtime Credits
will be applied:

“If during any given calendar month, the Network
Availability Percentage is below 98.0%, Buyer shall be entitled to a financial
credit in the form of a discount on the charges made by Seller to Buyer
pursuant to Section 1.2(e) of the Agreement applicable to such calendar
month.  The amount of such credit shall
be determined based on the Network Availability Percentage during such calendar
month and the corresponding credit amount as set forth above.  The amount of any credit due shall be
applied against the invoice sent to Buyer pursuant to Section 1.2(e) that is
applicable to such calendar month; provided, however, that if the
calculation of the Network Availability Percentage cannot reasonably be
completed before such invoice is sent out, the credit shall be applied against
the invoice for the following calendar month.”

NOW, THEREFORE, for
good and valuable consideration, the receipt and sufficiency of which is hereby
acknowledged, MOTIENT COMMUNICATIONS, MOTIENT SERVICES and AETHER agree as
follows:

 

 

1.             Concurrent
with the execution of this Amendment, AETHER and MOTIENT SERVICES shall also
sign the attached joint written notice to the Escrow Agent, pursuant to Section

2.             At
the request of AETHER, any unused balance of the prepayment set forth in

3.             At
the request of AETHER, any unused balance of the prepayment set forth in

applied to amounts owed under the Satellite Network Agreement, shall be applied
to amounts owed by AETHER to MOTIENT COMMUNICATIONS for provision of the
Service under the Terrestrial Network Agreement.

 

4.             Section
8(a) of the Terrestrial Network Agreement is amended and restated in its
entirety as follows:

 

“The Initial Term of this Agreement shall be November
29, 2000 through November 29, 2006 (the “Initial Term”). At the end of the
Initial Term, the Agreement may be renewed on terms and conditions and at rates
to be agreed in writing by the parties, provided that neither party is then in
default under the Agreement. Notwithstanding the foregoing, if, at the end of
the Initial Term, Aether Systems has made all of the prepayments described in

prepayment obligations under the Terrestrial Network Agreement and shall pay
for the Services under the Terrestrial Network Agreement as such Services are
consumed by AETHER and invoiced by MOTIENT COMMUNICATIONS.”

 

8.             Section
1.1 of the Satellite Network Agreement is hereby deleted and replaced with the

to in writing by the parties, provided that neither party is in default under
this Agreement. The Initial Term, and any extension thereof in accordance with
the preceding sentence, shall automatically end, with no further liability or
