adds to and updates information contained in the accompanying Base Shelf Prospectus and the documents incorporated by reference in the Base Shelf Prospectus for the purposes of the distribution of the

refer to the "Prospectus" as this Prospectus Supplement, together with the accompanying Base Shelf Prospectus and each document incorporated or deemed to be incorporated by reference in the Base Shelf

should rely only on the information contained in the Prospectus. Neither we nor the Underwriters have authorized anyone to provide you with different or additional information. If
the description of
the Offered Shares varies between this Prospectus Supplement and the Base Shelf Prospectus, you should rely on the information in this Prospectus Supplement. If anyone provides you with any

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Before filing this Prospectus Supplement, we and the Underwriters held roadshows that potential investors in the United States and in each of
the provinces of Canada, other than Quebec, were able to attend. We and the Underwriters provided marketing materials to those potential investors in connection with those roadshows. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
and the Underwriters are relying on a provision in applicable Canadian securities legislation that allows issuers in certain U.S. cross-border offerings to not have to file marketing
materials relating to those roadshows on the System for Electronic Document Analysis and Retrieval ("</FONT><FONT SIZE=2><B>SEDAR</B></FONT><FONT SIZE=2>") website at
www.sedar.com or include or incorporate by reference those marketing materials in this Prospectus Supplement. To rely on this exemption, we and the Underwriters must give a contractual right to
Canadian investors in the event the marketing materials contain a misrepresentation. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Accordingly,
we and the Underwriters signing the certificate contained in this Prospectus Supplement have agreed that in the event the marketing materials relating to the roadshows
described above contain a misrepresentation (as defined in securities legislation in each of the provinces of Canada, other than Quebec), a purchaser resident in a province of Canada, other than
Quebec, who was provided with those marketing materials in connection with the roadshows and who purchases the securities under the Prospectus during the period of distribution shall have, without
regard to whether the purchaser relied on the misrepresentation, rights against us and each Underwriter with respect to the misrepresentation which are equivalent to the rights under the securities
legislation of the jurisdiction of Canada where the purchaser is resident, subject to the defences, limitations and other terms of that legislation, as if the misrepresentation was contained in the
Prospectus. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;However,
this contractual right does not apply (i)&nbsp;to the extent that the contents of the marketing materials relating to the roadshows have been modified or superseded by a
statement in this Prospectus Supplement, and (ii)&nbsp;to any "comparables" (as such term is defined in National Instrument&nbsp;41-101&#151;</FONT><FONT SIZE=2><I>General Prospectus

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Prospectus contains references to Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues, which are not measures under GAAP and
which are provided as a complement to financial results presented in accordance with GAAP. We believe that our current shareholders and potential investors in our company use non-GAAP financial
measures, such as Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues, in making investment decisions about our company and measuring our operational results. We define Adjusted EBITDA as
earnings before interest, taxes, depreciation, amortization, stock-based compensation (for which we include related fees and taxes) and other charges (for which we include restructuring charges and
acquisition-related expenses). We define Adjusted EBITDA as a percentage of revenues as the quotient, expressed as a percentage, obtained from dividing Adjusted EBITDA for a period by revenues for the
corresponding period. For a reconciliation of Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues to net income determined in accordance with GAAP, see
"</FONT><FONT SIZE=2><I>Summary&#151;Summary Consolidated Financial Data</I></FONT><FONT SIZE=2>" in this Prospectus Supplement. See also "</FONT><FONT SIZE=2><I>Summary&#151;Baseline

considers these non-operating expenses to be outside the scope of our ongoing operations and the related expenses are not used by management to measure operations.
Accordingly, these expenses are excluded from Adjusted EBITDA, which we reference to both measure our operations and as a basis of comparison of our operations from period-to-period. Management
believes that
investors and financial analysts measure our business on the same basis, and we are providing the Adjusted EBITDA financial metric to assist in this evaluation and to provide a higher level of
transparency into how we measure our own business. However, Adjusted EBITDA and Adjusted </FONT></P>

as a percentage of revenues are non-GAAP financial measures and may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA and Adjusted EBITDA as a
percentage of revenues should not be construed as a substitute for net income determined in accordance with GAAP or other non-GAAP measures that may be used by other companies, such as EBITDA. The use
of Adjusted EBITDA and Adjusted EBITDA as a percentage of revenues does have limitations. In particular, we have completed seven acquisitions since the beginning of fiscal 2018 and may complete
additional acquisitions in the future that will result in acquisition-related expenses and restructuring charges. As these acquisition-related expenses and restructuring charges may continue as we
pursue our consolidation strategy, some investors may consider these charges and expenses as a recurring part of operations rather than expenses that are not part of operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>of
destination&#151;processes that move items (such as goods, people, information) from point A to point&nbsp;B. Supply chain management is broader than logistics and includes the sourcing,
procurement, conversion and storage of resources for consumption by an enterprise. Logistics and supply chain management have been evolving as companies are increasingly seeking automation and
real-time control of their supply chain activities. We believe companies are looking for integrated solutions, like the ones that we offer, for managing inventory in transit, conveyance units, people,
data and business documents. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
believe logistics-intensive organizations are seeking to reduce operating costs, differentiate themselves, improve margins and better serve customers. Global trade and transportation
processes are often manual and complex to manage. This is a consequence of the growing number of business partners participating in companies' global supply chains and a lack of standardized business
processes. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Additionally,
global sourcing, logistics outsourcing, imposition of additional customs and regulatory requirements, rapidly changing international trade arrangements and changes in
day-to-day business requirements are adding to the overall complexities that companies face in planning and executing in their supply chains. Whether a shipment is delayed at the border, a customer
changes an order or a breakdown occurs on the road, there are increasingly more issues that can significantly impact the execution of fulfillment schedules and associated costs. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These
challenges are heightened for suppliers that have end-customers frequently demanding narrower order-to-fulfillment periods, lower prices and greater flexibility in scheduling and
rescheduling deliveries. End-customers also want real-time updates on delivery status, adding considerable burden to supply chain management as process efficiency is balanced with affordable service. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
this market, the movement and sharing of data between parties involved in the logistics process is equally important to the physical movement of goods. Manual, fragmented and
distributed logistics solutions are often proving inadequate to address the needs of operators. Connecting manufacturers and suppliers to carriers on an individual, one-off basis is costly, complex
and risky for organizations dealing with many trading partners. Further, many of these solutions do not provide the flexibility, and real-time information exchange, required to efficiently accommodate
varied processes for organizations to remain competitive. We believe this presents an opportunity for logistics technology providers to unite this highly fragmented community and help customers
improve efficiencies in their operations. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;As
the market continues to change, we have been evolving to meet our customers' needs. While the rate of adoption of newer logistics and supply chain management technologies is
increasing, many organizations still have manual or antiquated business processes. We have been educating our prospects and customers on the value of connecting to trading partners through our Global
Logistics Network ("</FONT><FONT SIZE=2><B>GLN</B></FONT><FONT SIZE=2>") and automating, as well as standardizing, multi-party business processes. We believe that our target customers are
increasingly looking for a single source, neutral, network-based solution provider who can help them manage the end-to-end shipment process&#151;from researching global trade information, to
the booking of a shipment, to the tracking of that shipment as it moves, to the regulatory compliance filings to be made during the move and, finally, to the settlement and audit of the invoice. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Additionally,
regulatory initiatives mandating electronic filing of shipment information with customs authorities require companies to automate aspects of their shipping processes to
remain compliant and competitive. Our customs compliance technology helps shippers, transportation providers, freight forwarders and other logistics intermediaries to securely and electronically file
shipment and tariff/duty information with customs authorities and self-audit their own efforts. Our technology also helps carriers and freight forwarders efficiently coordinate with customs brokers
and agencies to expedite cross-border shipments. While many compliance initiatives started in the US, compliance has now become a global issue with significantly more international shipments crossing
several borders on the way to their final destinations. </FONT></P>

 <P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Increasingly,
data and content have become central to supply chain planning and execution. The review of people, goods, services and/or commodities against comprehensive lists of
restricted or sanctioned
parties published by governments and international organizations has become an essential compliance requirement as the penalties for doing business with sanctioned parties can be far-reaching and
severe. Our content and compliance solutions help simplify and automate the screening processes. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Complex
international supply chains are also affected by logistics service provider performance, capacity, and productivity, as well as regulatory frameworks such as free trade
agreements and trade sanctions. We believe our global trade data, denied party screening, trade regulations and free-trade agreement and duty rate and calculation solutions help customers improve
their sourcing, compliance, landed-cost, and transportation lane and provider selection processes. </FONT></P>

electronic transportation network that provides global air carriers and ground handlers with shipment scanning and tracking solutions. CORE has been connecting commercial airlines, ground handlers and
the wider logistics community with trading partners and government postal authorities around the world for more than 10&nbsp;years. Customers use CORE's network to accurately track international

restricted party screening processes and export licensing. The purchase price for the acquisition was approximately US$249&nbsp;million at February&nbsp;12, 2019 (approximate C$330&nbsp;million
purchase price), net of cash acquired, which consisted of cash funded from a combination of drawing on our Credit Facility and issuance to the sellers of 0.3&nbsp;million Common Shares from
treasury. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;On
January&nbsp;28, 2019, we announced that we had amended and increased our US$150&nbsp;million senior secured revolving credit facility to a US$350&nbsp;million revolving
operating credit facility (the "</FONT><FONT SIZE=2><B>Credit Facility</B></FONT><FONT SIZE=2>"). The Credit Facility, for which a Canadian chartered bank that is an affiliate of BMO is sole lead and
arranger, is available for general corporate purposes, including the financing of ongoing working capital needs and acquisitions, such as the Visual Compliance transaction. With the approval of the
lenders, the Credit Facility can be further expanded to a total of US$500&nbsp;million. The Credit Facility has a five-year maturity with no fixed repayment dates prior to the end of the five-year
term ending in January 2024. Borrowings under the Credit Facility are secured by a first charge over substantially all of our assets. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
the ordinary course, we consider and negotiate potential acquisition opportunities to achieve our business and growth strategies. Accordingly, we may have proposals, letters of
intent, exclusivity arrangements or conditional agreements outstanding at any time. However, there can be no assurance that any of these discussions will result in a definitive agreement and, if they
do, what the terms or timing of any acquisition would be or that such acquisition will be completed by us. At the present time, we are actively considering two potential acquisitions, neither of which
is expected to be material to us. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We internally measure and manage our "baseline calibration," a non-GAAP financial measure, which we define as the difference between our
"baseline revenues" and "baseline operating expenses". We define our "baseline revenues," a non-GAAP financial measure, as our visible, recurring and contracted revenues. Baseline revenues are not a
projection of anticipated total revenues for a period as they exclude any anticipated or expected new sales for a period beyond the date that the baseline revenues are measured. We define our
"baseline operating expenses," a non-GAAP financial measure, as our total expenses less interest, investment income, taxes, depreciation and amortization, stock-based compensation (for which we
include related costs and taxes), acquisition-related costs and restructuring charges. Baseline operating expenses are not a projection of anticipated total expenses for a period as they exclude any
expenses associated with anticipated or expected new sales for a period beyond the date that the baseline expenses are measured. Our baseline calibration is not a projection of net income for a period
as determined in accordance with GAAP, or Adjusted EBITDA for a period, as it excludes anticipated or expected new sales for a period beyond the date that the baseline calibration is measured,
excludes any costs of goods sold or other expenses associated with such new sales, and excludes the expenses identified as excluded in the definition of "baseline operating expenses," above. We
calculate and disclose "baseline revenues," "baseline operating expenses" and "baseline calibration" because management uses these metrics in determining its planned levels of expenditures for a
period and we believe this information is useful to our investors. However, because these metrics are limited estimated operating metrics that do not have comparable GAAP measures, we are unable to
provide quantitative reconciliations of these measures to GAAP measures without unreasonable efforts and accordingly are omitting this information. These metrics are estimated operating metrics and
not projections, nor actual financial results, and are not indicative of current or future performance. These metrics do not have a standardized meaning prescribed by GAAP and are unlikely to be
comparable to similarly-titled metrics used by other companies and are not a replacement or proxy for any GAAP measure. </FONT></P>

Mail and PinPoint. In fiscal 2018, we acquired ShipRush, PCSTrac and MacroPoint. We're unable to predict whether or when we will be able to identify any appropriate products, technologies or
businesses for acquisition, or the likelihood that any potential acquisition will be available on terms acceptable to us or will be completed. We also, from time to time, take on investments in other
business initiatives, such as the implementation of new systems. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Acquisitions
and other business initiatives involve a number of risks, including: substantial investment of funds, diversion of management's attention from current operations; additional
demands on resources, systems, procedures and controls; and disruption of our ongoing business. Acquisitions specifically involve risks, including: difficulties in integrating and retaining all or
part of the acquired business, its customers and its personnel; assumption of disclosed and undisclosed liabilities; dealing with unfamiliar laws, customs and practices in foreign jurisdictions; and
the effectiveness of the acquired company's internal controls and procedures. In addition, we may not identify all risks or fully assess risks identified in connection with an investment. As well, by
investing in such initiatives, we may deplete our cash resources or dilute our shareholder base by issuing additional shares. Furthermore, for acquisitions, there is a risk that our valuation
assumptions, customer retention expectations and our models for an acquired product or business may be erroneous or inappropriate due to foreseen or unforeseen circumstances and thereby cause us to
overvalue an acquisition target. There is also a risk that the contemplated benefits of an acquisition or other investment may not materialize as planned or may not materialize within the time period
or to the extent anticipated. The individual or combined effect of these risks could have a material adverse effect on our business. </FONT></P>

System or network failures, information security breaches, including unauthorized parties obtaining access to
our users' personal or other data, or any other data protection compliance issue, or other cyber-security threats in connection with our services and products could have a material adverse effect on
our operations, reduce our sales, impair our reputation, increase costs or result in liability claims, and seriously harm our business.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We rely on information technology networks and systems to process, transmit and store electronic information, including any information relating
to an identified or identifiable natural person ("personal data"). We leverage our internal IT infrastructures, and those of our service providers, to enable, sustain, and support our business
interests. In the event that we or our service providers are unable to prevent, detect, and remediate cyber-based attacks, computer viruses, breaches of customer privacy or other security incidents in
a timely manner, our operations could be disrupted or we could incur financial, legal or reputational losses arising from misappropriation, misuse, leakage, falsification or intentional or accidental
release or loss of information maintained in our information systems and networks, including personal information of our employees and our customers. Any disruption to our services and products, our
own information systems or communications networks or
those of third-party providers on which we rely as part of our own product offerings could result in the inability of our customers to receive our products for an indeterminate period of time. Our
ability to deliver our products and services depends on the development and maintenance of internet infrastructure by third parties. This includes maintenance of reliable networks with the necessary
security, speed, data capacity and bandwidth. While our services are designed to operate without interruption, we have experienced, and may in the future experience, interruptions and delays in
services and availability from time to time. In the event of a catastrophic event with respect to one or more of our systems, we may experience an extended period of system unavailability, which could
negatively impact our relationship with customers. Our services and products may not function properly for reasons which may include, but are not limited to, the

addition, any disruption to the availability of customer information, or any compromise to the integrity or confidentiality of customer information in our systems or networks, or the
systems or networks of third parties on which we rely, could result in our customers being unable to effectively use our products or services or being forced to take mitigating actions to protect
their information. Back-up and redundant systems may be insufficient or may fail and result in a disruption of availability of our products or services to our customers or the integrity or
availability of our customers' information. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Furthermore,
outside parties may attempt to fraudulently induce our employees or employees of our vendors to disclose sensitive information in order to gain access to our data. The
number and complexity of these threats continue to increase over time. Although we develop and maintain systems and controls designed to prevent these events from occurring, and we have a process to
identify and mitigate threats, the development, and maintenance of these systems, controls, and processes require ongoing monitoring and updating as technologies change and efforts to overcome
security measures become more sophisticated. Despite our efforts, the possibility of these events occurring cannot be eliminated entirely. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Some
jurisdictions have enacted laws requiring companies to notify individuals of data security breaches involving certain types of personal data and/or, as set out under the General
Data Protection Regulation (2016/679) ("GDPR"), is likely to result in a high risk to the rights and freedoms of these individuals, and in some cases our agreements with certain customers require us
to notify them in the event of a security incident. Such mandatory disclosures could lead to negative publicity and may cause our current and prospective customers to lose confidence in the
effectiveness of our data security measures. Moreover, if a high-profile security breach occurs with respect to another SaaS provider,
customers may lose trust in the security of the SaaS business model generally, which could adversely impact our ability to retain existing customers or attract new ones. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
actual or perceived threat of disruption to our services or any compromise of personal data, including customer information, or any actual or perceived violations of cybersecurity
regulations, such as, where applicable, the Network and Information Systems Directive (EU) 2016/1148 ("NIS Directive") and any national implementing legislation, could impair our reputation and cause
us to lose customers or revenue, or face litigation or administrative proceedings, necessitate customer service or repair work that would involve substantial costs and distract management from
operating our business. Despite the implementation of advanced threat protection, information and network security measures and disaster recovery plans, our systems and those of third parties on which
we rely may be vulnerable. If we are unable (or are perceived as being unable) to prevent, or promptly identify and remedy, such outages and breaches, our operations may be disrupted, our business
reputation could be adversely affected, and there could be a negative impact on our financial condition and results of operations. </FONT></P>

Our existing customers might cancel contracts with us, fail to renew contracts on their renewal dates, and/or
fail to purchase additional services and products, and we may be unable to attract new customers.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We depend on our installed customer base for a significant portion of our revenues including a significant portion of our revenues from
subscription offerings. We have significant contracts with our license customers for ongoing support and maintenance, as well as significant service contracts that provide recurring services revenues
to us. In addition, our installed customer base has historically generated additional new license and services revenues for us. Service contracts are generally renewable at a customer's option and/or
subject to cancellation rights, and there are generally no mandatory payment obligations or obligations to license additional software or subscribe for additional services. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
our customers fail to renew their subscriptions or service contracts, fail to purchase additional services or products, or we are unable to attract new customers, then our revenues
could decrease and our operating results could be adversely affected. Costs associated with renewals of subscriptions or service agreements from our installed customer base are lower than costs
associated with generating revenue from new customers. Therefore, if we are unable to retain revenue from installed customers, even if losses are offset by an increase in new customers, our operating
results could be adversely affected. Factors influencing such contract terminations could include changes in the financial circumstances of our customers, dissatisfaction with our products or
services, our retirement or lack of support for our legacy products and services, our customers selecting or building alternate technologies
to replace us, the cost of our products and services as compared to the cost of products and services offered by our competitors, our ability to attract, hire and maintain qualified personnel to meet
customer needs, consolidating activities in the market, and changes in our customers' business or in regulation impacting our customers' business that may no longer necessitate the use of our products
or services, general economic or market conditions, or other reasons. Further, our customers could delay or terminate implementations or use of our services and products or be reluctant to migrate to
new products. Such customers will not generate the revenues we may have anticipated within the timelines anticipated, if at all, and may be less likely to invest in additional services or products
from us in the future. We may not be able to adjust our expense levels quickly enough to account for any such revenue losses. In addition, loss of one or more of our key customers could adversely
impact our competitive position in the marketplace and hurt our credibility and ability to attract new customers. </FONT></P>

Disruptions in the movement of freight could negatively affect our revenues.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our business is highly dependent on the movement of freight from one point to another since we generate transaction revenues as freight is moved
by, to or from our customers. If there are disruptions in the movement of freight, proper reporting or the overall volume of international shipments, whether as a result of labor disputes, weather or
natural disaster, terrorist events, political instability, changes in cross border trade agreements, contagious illness outbreaks, or otherwise, then the traffic volume on our Global Logistics Network
will be impacted and our revenues will be adversely affected. As these types of freight disruptions are generally unpredictable, there can be no assurance that our business, results of operations and
financial condition will not be adversely affected by such events. Further, governments may turn to trade barriers and trade protectionist policies to protect their domestic industries against foreign
imports and curtail or reduce shipping demand. The U.S. government has indicated it may seek to implement more protective trade measures, which yields significant uncertainty about the future
relationship (including with respect to trade policies, tariffs, treaties, sanctions, laws and regulations) between the U.S., China and other exporting countries. For example, trade tensions between
the U.S. and China have resulted in both governments imposing tariffs. Increasing government trade protectionism may increase the cost of goods exported globally, the length of time required to
transport goods and the associated export risks, which may significantly affect the quantity of goods to be shipped, shipping time schedules, voyage costs and other associated costs. As such, any
increase in trade barriers or restrictions on trade, including the U.S. position on trade with China, may have a material and adverse impact on our customer's business, operating results, financial
condition and ultimately, affect their ability to make timely payments to us and to renew and increase the number of subscriptions, service agreements or licenses with us. Such a result may have a
material adverse effect on our business, results of operations and financial condition. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Our performance is substantially dependent on the performance of our highly qualified management, technical expertise, and sales and marketing
personnel, which we regard as key individuals to our business. We do not maintain life insurance policies on any of our employees that list
Descartes as a loss payee. Our success is highly dependent on our ability to identify, hire, train, motivate, promote, and retain key individuals. Significant competition exists for management and
skilled personnel. If we fail to cross train key employees, particularly those with specialized knowledge it could impair our ability to provide consistent and uninterrupted service to our customers.

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Demand for our products depends in large part upon the level of capital and operating expenditures by many of our customers. Decreased capital

financial markets may adversely impact the availability of credit already arranged and the availability and cost of credit in the future, which could result in the delay or cancellation of projects or
capital programs on which our business depends. In addition, disruptions in the financial markets may also have an adverse impact on regional economies or the world economy, which could negatively
impact the capital and operating expenditures of our customers. These conditions may reduce the willingness or ability of our customers and prospective customers to commit funds to purchase our
products and services, or their ability to pay for our products and services after purchase. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Historically, we have financed our operations primarily through cash flows from our operations, the sale of our equity securities and borrowing
under our Credit Facility. In addition to our current cash and available debt facilities, we may need to raise additional debt or equity capital to repay existing debt, fund expansion of our
operations, to enhance our services and products, or to acquire or invest in complementary products, services, businesses or technologies. However, there can be no assurance that we will be able to
undertake incremental financing transactions. If we raise additional funds through further issuances of convertible debt or equity securities, our existing shareholders could suffer significant
dilution and any new equity securities we issue could have rights, preferences and privileges superior to those attaching to our Common Shares. Our current Credit Facility contains, and any debt
financing secured by us in the future could contain restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for
us to obtain additional capital and to pursue business opportunities, including potential acquisitions. In addition, we may not be able to obtain additional financing on terms favorable to us, if at
all. If adequate funds are not available on terms favorable or at all, our operations and growth strategy may be adversely affected and the market price for our Common Shares could decline. </FONT></P>

We may have exposure to greater than anticipated tax liabilities or expenses.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We are subject to income and non-income taxes in various jurisdictions and our tax structure is subject to review by both domestic and foreign
taxation authorities and currently has tax audits open in a number of jurisdictions in which we operate. On a quarterly basis, we assess the status of these audits and the potential for adverse
outcomes to determine whether a provision for income and other taxes is appropriate. The timing of the resolution of income tax audits is highly uncertain, and the amounts ultimately paid, if any,
upon resolution of the issues raised by the taxing authorities may differ from any amounts that we accrue from time to time. The actual amount of any change could vary significantly depending on the
ultimate timing and nature of any settlements. We cannot currently provide an estimate of the range of possible outcomes. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
determination of our worldwide provision for income taxes and other tax liabilities requires significant judgment. In the ordinary course of a global business, there are many
transactions and calculations where the ultimate tax outcome is uncertain. Any audit of our tax filings could materially change the amount of current and deferred income tax assets and liabilities. We
have recorded a valuation allowance against a portion of our net deferred tax assets. If we achieve a consistent level of profitability, the likelihood of further reducing our deferred tax valuation
allowance for some portion of the losses incurred in prior periods in one of our jurisdictions will increase. We calculate our current and deferred tax provision based on estimates and assumptions
that could differ from the actual results reflected in income tax returns filed during subsequent years. Adjustments based on filed returns are generally recorded in the period when the tax returns
are filed and the global tax implications are known. Our estimate of the potential outcome for any uncertain tax issue is based on a number of assumptions. Any further changes to the valuation
allowance for our deferred tax assets would also result in an income tax recovery or income tax expense, as applicable, on the consolidated statements of operations in the period in which the
valuation allowance is changed. </FONT></P>

accordance with their functional specifications. We may also have disputes with key suppliers for damages incurred which, depending on resolution of the disputes, could impact the ongoing quality,
price or availability of the services or products we procure from the supplier. Limitation of liability provisions in certain third-party contracts may not be enforceable under the laws of some
jurisdictions. As a result, we could be required to pay substantial amounts of damages in settlement or upon the determination of any of these types of claims, and incur damage to our reputation and
products. The likelihood of such claims and the amount of damages we may be required to pay may increase as our customers increasingly use our services and products for critical business functions, or
rely on our services and products as the systems of record to store data for use by other customer applications. Our insurance may not cover potential claims, or may not be adequate to cover all costs
incurred in defense of potential claims or to indemnify us for all liability that may be imposed. A claim brought against us that is uninsured or underinsured could result in unanticipated costs,

intellectual property rights could be costly regardless of venue. In order to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these
rights. The Company is currently involved in, and expects to remain involved in, certain litigation to protect its intellectual property from infringement or other violations by third parties. In
addition, further litigation may be necessary in the future to enforce our intellectual property rights, to protect our trade secrets, to determine the validity and scope of the intellectual property
rights of others or to defend against claims of infringement or other violation or invalidity. Litigation brought to protect and enforce our intellectual property rights could be costly, time
consuming and distracting to management and could result in the impairment or loss of portions of our intellectual property. Furthermore, our efforts to enforce our intellectual property rights may be
met with defenses, counterclaims and countersuits attacking the validity and enforceability of our intellectual property rights and/or exposing us to claims for damages in any related counterclaims or
countersuits. Our inability to protect our proprietary technology against unauthorized copying or use, as well as any costly litigation or diversion of our management's attention and resources, could
delay further sales or the implementation of our solutions, impair the functionality of our solutions, delay introductions of new solutions, result in our substituting inferior or more costly
technologies into our solutions, or injure our reputation. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The impacts of human activity on global climate change have attracted considerable public and scientific attention, as well as the attention of
governments. Efforts are being made to reduce greenhouse gas emissions and energy consumption, including those from automobiles and other modes of transportation. The added cost of any environmental
regulation, taxes, charges, assessments or penalties levied or imposed on our customers in light of these efforts could result in additional costs for our customers, which could lead them to reduce
use of our services. There are also a number of legislative and environmental regulatory initiatives internationally that could restrict or negatively impact our operations or increase our costs.
Additionally, environmental regulation, taxes, charges, assessments or penalties could be levied or imposed directly on us. Any enactment of laws or passage of regulations regarding greenhouse gas
emissions by Canada, the United States, or any other jurisdiction we conduct our business in, could adversely affect our operations and financial results. </FONT></P>

our customers in compliance with such privacy laws. The functional and operational requirements and costs of
compliance with privacy laws may adversely impact our business, and failure to enable our products to comply privacy laws could lead to significant fines and penalties imposed by regulators, as well
as claims by our customers or third parties. Additionally, all of these domestic and international legislative and regulatory initiatives could adversely affect our customers' ability or desire to

we have implemented various measures intended to enable us to comply with applicable privacy laws and contractual obligations, these measures may not always be effective and do not
guarantee compliance. In addition, privacy laws and regulations are evolving and subject to potentially differing interpretations and may be modified, interpreted and applied in an inconsistent manner
from one jurisdiction to another, and may conflict with one another, other requirements or legal obligations, or our practices. As a result, our practices may not comply in the future with all such
laws, regulations, requirements and obligations. Further, the existence and need to comply in certain markets could impact our ability to offer our platform in those markets (without taking additional
compliance steps). </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These
privacy or data protection laws and regulations may also result in increasing regulatory and public scrutiny, escalating levels of enforcement and sanctions, and impose compliance
challenges on our business. For instance, expanding definitions of what constitutes "personal data" (or equivalent) within the European Union, the United States and elsewhere may increase our
compliance costs. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Any
failure or perceived failure to comply with federal, state or foreign laws or regulations, contractual or other legal obligations related to data privacy or data protection may

For example, administrative fines of up to the greater of &euro;20&nbsp;million and 4% of our global turnover can be imposed for breaches of the GDPR; we may also be liable should any

and may issue additional equity securities to finance operations, acquisitions or other projects. We cannot predict the size of future issuances of equity securities or the size and terms of future
issuances of debt instruments or other securities convertible into equity securities or the effect, if any, that future issuances and sales of our securities
will have on the market price of the Common Shares. Any transaction involving the issuance of previously authorized but unissued Common Shares, or securities convertible into Common Shares, would
result in dilution, possibly substantial, to security holders. Exercises of presently outstanding share options may also result in dilution to security holders. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Sales
of substantial amounts of our securities, or the availability of such securities for sale, could adversely affect the prevailing market prices for our securities and dilute
investors' earnings per share. A decline in the market prices of our securities could impair our ability to raise additional capital through the sale of securities should we desire to do so. </FONT></P>

We do not currently intend to pay any cash dividends on our Common Shares in the foreseeable future.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have not declared or paid any cash dividends on our Common Shares to date. Although we review our dividend policy from time to time, our
current policy is to retain earnings to finance expansion and to develop, license and acquire new products and to otherwise reinvest in its business. Therefore, we do not anticipate paying cash
dividends in the foreseeable future. Until we pay dividends, which we may never do, shareholders will not be able to receive return on their Common Shares unless they sell them at an amount greater
than the price at which shares were acquired. </FONT></P>

Discretion in use of proceeds.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We will have broad discretion concerning the use of the net proceeds of the Offering as well as the timing of any expenditures. As a result, a
purchaser of Offered Shares will be relying on the judgment of management with respect to the application of the net proceeds of the Offering. Management may use the net proceeds of the Offering in
ways that an investor may not consider desirable. The results and the effectiveness of the application of the net proceeds are uncertain. If the net proceeds are not applied effectively, our financial
performance and financial condition may be adversely affected and the Common Shares could lose value. </FONT></P>

Future sales of Common Shares by our existing shareholders could cause our Common Share price to fall.  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If our shareholders sell substantial amounts of the Common Shares in the public market, the market price of the Common Shares could fall. The
perception among investors that these sales will occur could also produce this effect. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We expect to receive net proceeds from the sale of the Common Shares in this Offering of approximately US$205.4&nbsp;million, after deducting
underwriting fees of approximately US$6.9&nbsp;million and estimated offering expenses of approximately US$0.7 million. If the Over-Allotment Option is exercised in full, the net proceeds that we
will receive from the Offering are estimated to be approximately US$236.3&nbsp;million after deducting underwriting fees of approximately US$8.0&nbsp;million and estimated offering expenses of
approximately US$0.7 million. See "</FONT><FONT SIZE=2><I>Underwriting (Conflicts of Interest)</I></FONT><FONT SIZE=2>" in this Prospectus Supplement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
intend to use the net proceeds from this Offering to repay outstanding indebtedness under our Credit Facility, for potential future acquisition opportunities and for general corporate
purposes. See "</FONT><FONT SIZE=2><I>Relationship Between Descartes and the Underwriters"</I></FONT><FONT SIZE=2>. Amounts repaid under the Credit Facility may be re-borrowed and used by Descartes
for funding future acquisitions and for general corporate purposes, subject in each case to satisfaction of certain covenant and financial ratios. The current amount
outstanding under the Credit Facility was used by us to fund acquisitions, including part of the purchase price for the acquisition of Visual Compliance and to fund the up-front consideration that was
payable in connection with the acquisition of CORE. See "</FONT><FONT SIZE=2><I>Summary&#151;Recent Developments</I></FONT><FONT SIZE=2>" in this Prospectus Supplement. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
invest our cash balances in accordance with our investment policy as approved by our board of directors. This generally results in cash being invested in short-term, interest bearing
securities such as government securities and other highly rated investment-grade securities. Our board of directors has established an investment policy which requires that our cash reserves be
invested with the purpose of ensuring the highest level of safety of principal, liquidity and yield, in that order of importance. Our audit committee is responsible for reviewing and approving our
investment policy on an annual basis. While we currently anticipate that we will use the net proceeds of the Offering received as set forth above, we may re-allocate these proceeds from time to time
having consideration to our strategy relative to the market and other conditions in effect at the time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;From
time to time, we evaluate various potential acquisition opportunities, some of which could, if consummated, have a material impact on us. There can be no assurance that we will be
able to identify acquisition opportunities that meet our strategic objectives, or to the extent such opportunities are identified, that we will be able to negotiate acquisition terms that are
acceptable to us. At this time, we are actively considering two potential acquisitions. Neither of these acquisitions is expected to be material to us. It is not possible to predict whether
discussions may lead to the announcement of a transaction, or the timeframe within which this might occur. However, we cannot preclude the possibility that agreement on one or more acquisition
transactions will be reached in the weeks or months following the closing of this Offering. In such circumstances, as noted above, all or a portion of the net proceeds of the Offering received by us
may be allocated to effect such acquisitions. See "</FONT><FONT SIZE=2><I>Risk Factors</I></FONT><FONT SIZE=2>" in this Prospectus Supplement. </FONT></P>

United States  </B></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following discussion summarizes certain U.S. federal income tax considerations generally applicable to the ownership and taxable disposition
of our Common Shares by a U.S. holder. For purposes of this discussion, a "U.S. holder" is a beneficial owner of Common Shares that has acquired such shares for cash pursuant to this Offering and
holds such shares as capital assets within the meaning of section&nbsp;1221 of the U.S. Internal Revenue Code of 1986, as amended (the "</FONT><FONT SIZE=2><B>Code</B></FONT><FONT SIZE=2>"), and is
any of the following: (i)&nbsp;a citizen or individual resident of the United States and not of Canada, (ii)&nbsp;a corporation (or any entity treated as a corporation for U.S. federal income tax
purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia, (iii)&nbsp;an estate, the income of which is includible in gross income for U.S.
federal income tax purposes regardless of its source, or (iv)&nbsp;a trust if (a)&nbsp;a court within the United States is able to exercise primary supervision over the administration of the trust
and one or more U.S. persons (as defined in the Code) have the authority to control all substantial decisions of the trust or (b)&nbsp;it has a valid election in effect under applicable Treasury
regulations to be treated as a U.S. person. This discussion does not address (i)&nbsp;any other aspect of U.S. federal tax law, such as the gift or estate tax, (ii)&nbsp;the 3.8% tax on net
investment income, (iii)&nbsp;any aspect of state, local or non-U.S. tax law, (iv)&nbsp;the application of any tax treaty, or (v)&nbsp;any aspects of U.S. federal income taxation applicable to
U.S. holders holding options, warrants or other rights to acquire Common Shares. Further, this discussion does not address the U.S. federal income tax consequences to U.S. holders that are subject to
special treatment under U.S. federal income tax laws, including, but not limited to U.S. holders that own, have owned or will own directly, indirectly or by attribution, 10% or more of the total
combined voting power or total value of our stock; broker dealers; banks or other financial institutions; insurance companies; real estate investment trusts; regulated investment companies; U.S.
holders who have elected mark-to-market accounting; tax-exempt organizations; governments, agencies or instrumentalities thereof, or entities they control; U.S. holders who hold Common Shares as part
of a "straddle," "hedge," or "conversion transaction" with other investments; individual retirement or other tax deferred accounts; U.S. holders whose functional currency is not the U.S. dollar or who
hold Common Shares through a "qualified business unit" whose functional currency is not the U.S. dollar; partnerships (or entities or arrangements treated as partnerships for U.S. federal income tax
purposes) or the partners therein; S&nbsp;corporations; U.S. holders subject to the alternative minimum tax; or U.S. expatriates and certain former long-term residents of the United States. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;If
a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) owns Common Shares, the tax treatment of a partner in the partnership will
generally depend upon the status of the partner and the activities of the partnership. Partnerships holding Common Shares and their partners should consult their tax advisers regarding an investment
in Common Shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
discussion is based upon the provisions of the Code, the Treasury regulations promulgated thereunder, judicial decisions, and published rulings, administrative procedures, and other
guidance of the U.S. Internal Revenue Service ("</FONT><FONT SIZE=2><B>IRS</B></FONT><FONT SIZE=2>"), all as in effect as of the date of this Prospectus Supplement. These authorities are subject to
change and to differing interpretations, possibly with retroactive effect, which could result in U.S. federal income tax consequences different from those summarized below. No ruling has been or is

Distributions on the Common Shares  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We have never declared or paid any dividends on our Common Shares and we do not intend to pay dividends in the foreseeable future. Subject to
the discussion below under "</FONT><FONT SIZE=2><I>Passive Foreign Investment Company Rules</I></FONT><FONT SIZE=2>," U.S. holders generally will treat the gross amount of any distributions that we
pay, without reduction for Canadian withholding tax (see "</FONT><FONT SIZE=2><I>Certain Income Tax Considerations&#151;Canada&#151;Dividends</I></FONT><FONT SIZE=2>"), as dividend
income for U.S. federal income tax purposes to the extent of our current and accumulated earnings and profits, as determined under U.S. federal income tax principles. To the extent that any
distribution is not paid out of our current and accumulated earnings and profits, the distribution would be treated as a return of capital to the extent of, and in reduction of, the U.S. holder's
adjusted tax basis in the Common Shares with respect to which the distribution is made. To the extent that a distribution to a U.S. holder is not paid out of our current and accumulated earnings and
profits and exceeds a U.S. holder's adjusted tax basis, it would be treated as a gain from the taxable disposition of the applicable Common Shares (which gain would be taxable in the manner described
below under "Sale or Other Taxable Disposition of Common Shares"). Because we do not maintain calculations of our earnings and profits under U.S. federal income tax principles, U.S. holders should
assume that any distribution with respect to our Common Shares would need to be reported as dividend income. Corporate U.S. holders that own less than 10% of our stock (by voting power and value) will
not be eligible for a dividends received deduction with respect to dividends paid to them on our Common Shares. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;With
respect to non-corporate U.S. holders, certain dividends received from a qualified foreign corporation (such dividends, "</FONT><FONT SIZE=2><B>qualified dividend
income</B></FONT><FONT SIZE=2>") may be subject to reduced rates of taxation. A qualified foreign corporation includes a foreign corporation that is not a PFIC for the taxable year
of the corporation in which the dividend is paid, or any preceding taxable year, and that is eligible for the benefits of a comprehensive income tax treaty with the United States that the U.S.
Treasury Department determines to be satisfactory for these purposes and that includes an exchange of information provision. The U.S. Treasury Department has determined that the income tax treaty
between Canada and the United States meets these requirements. Non-corporate holders that do not meet a minimum holding period requirement during which they are not protected from the risk of loss or
that elect to treat the dividend income as "investment income" pursuant to section&nbsp;163(d)(4) of the Code (dealing with the deduction for investment interest expense) will not be eligible for
the reduced rates of taxation applicable to qualified dividend income regardless of our status as a "qualified foreign corporation." In addition, the rate reduction will not apply to dividends if the
recipient of a dividend is obligated to make related payments with respect to positions in substantially similar or related property. This disallowance applies even if the minimum holding period has
been met. </FONT></P>

Receipt of Foreign Currency  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The amount of any distribution paid to a U.S. holder in foreign currency, or the amount realized on the sale or other taxable disposition of
Common Shares in exchange for foreign
currency, generally will be equal to the U.S. dollar value of such foreign currency based on the exchange rate applicable on the date of receipt (regardless of whether such foreign currency is
converted into U.S. dollars at that time). A U.S. holder will have a tax basis in the foreign currency received equal to its U.S. dollar value on the date of receipt. Any U.S. holder who converts or
otherwise disposes of the foreign currency after the date of receipt may have a foreign currency exchange gain or loss that would be treated as ordinary income or loss. Different rules apply to U.S.
holders who use the accrual method of tax accounting. Each U.S. holder should consult its tax adviser regarding the U.S. federal income tax consequences of receiving, owing, and disposing of foreign
currency. </FONT></P>

Foreign Tax Credit  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;A U.S. holder may be eligible to elect to claim a U.S. foreign tax credit against its U.S. federal income tax liability, subject to applicable
limitations and holding period requirements, for Canadian tax withheld, if any, from distributions on our Common Shares. A U.S. holder that does not elect to claim a U.S. foreign tax credit may
instead claim a deduction for Canadian tax withheld, but only for a taxable year in which the U.S. holder elects to do so with respect to all foreign taxes paid or accrued in such taxable year. The
rules relating to U.S. foreign tax credits are complex, and each U.S. holder should consult its tax adviser regarding the application of those rules and the manner of computing the allowable amount
of, and limitations on, U.S. foreign tax credits. </FONT></P>

Passive Foreign Investment Company Rules  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Special U.S. federal income tax rules apply to U.S. persons owning shares of a "passive foreign investment company"
("</FONT><FONT SIZE=2><B>PFIC</B></FONT><FONT SIZE=2>"). In general, a non-U.S. corporation such as our company will be classified as a PFIC in a particular taxable year if either:
(i)&nbsp;75&nbsp;percent or more of the corporation's gross income for the taxable year is passive income, or (ii)&nbsp;50&nbsp;percent or more of the value of the corporation's assets
(determined on the basis of a quarterly average) during such year produce or are held for the production of passive income. For this purpose, "passive income" generally includes interest, dividends,
rents, royalties and certain gains. If we were to be treated as a PFIC for any year, U.S. holders may be subject to adverse tax consequences upon a sale, exchange, or other disposition of the Common
Shares, or upon the receipt of certain "excess distributions" in respect of the Common Shares. Dividends paid by a PFIC are not eligible for treatment as qualified dividend income. Further adverse tax
consequences could result if we were to be treated as a PFIC and any of our subsidiaries were also treated as PFICs. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We
believe that we have not been a PFIC with respect to any prior taxable year and we do not anticipate becoming a PFIC for the current, or any subsequent, taxable year. However, the
determination as to whether we are a PFIC for any taxable year is based on the application of complex U.S. federal income tax rules, which are subject to differing interpretations, and such status is
not determinable until after the end of each such taxable year. Further, the determination of PFIC status is based in part on the mix, use and value of our assets, which values may be treated as
changing for U.S. </FONT></P>

manner. Certain elections may be available to U.S. holders of our Common Shares that may mitigate some of the adverse consequences that could result if we were to be treated as a PFIC. U.S. holders

Information Reporting and Backup Withholding  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Except in the case of corporations or other exempt holders, dividends paid to a U.S. holder on Common Shares, and proceeds received by a U.S.

an accurate taxpayer identification number on a properly completed IRS Form&nbsp;W-9 and certifies that no loss of exemption from backup withholding has occurred and that the U.S. holder is not
otherwise subject to backup withholding. Backup withholding is not an additional tax. The amount of any backup withholding will be allowed as a credit against the U.S. holder's U.S. federal income tax
liability and may entitle the U.S. holder to a refund, provided that certain required information is timely furnished to the IRS. </FONT></P>

Non-Residents of Canada  </I></FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The following is a summary of the principal Canadian federal income tax considerations generally applicable to investors who acquire as
beneficial owner Common Shares pursuant to this Offering and who at all relevant times for purposes of the Tax Act , are not and are not deemed to be resident in Canada, deal at arm's length with
Descartes, are not affiliated with Descartes, hold the Common Shares as capital property and do not and will not use or hold, and are not and will not be deemed to use or hold, such Common Shares in
carrying on a business in Canada (a "</FONT><FONT SIZE=2><B>Non-Resident Shareholder</B></FONT><FONT SIZE=2>"). Special rules, which are not discussed in this summary, may apply to a Non-Resident
Shareholder that is an insurer carrying on an insurance business in Canada and elsewhere. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
summary is based upon the facts set out in the Prospectus, the current provisions of the Tax Act and the current administrative policies and assessing practices of the Canada
Revenue Agency ("</FONT><FONT SIZE=2><B>CRA</B></FONT><FONT SIZE=2>") made publicly available in writing prior to the date hereof. This summary also takes into account specific proposals to amend the
Tax Act announced prior to the date hereof by or on behalf of the Minister of Finance (Canada) (the "</FONT><FONT SIZE=2><B>Proposed Amendments</B></FONT><FONT SIZE=2>") and assumes that the Proposed
Amendments will be enacted as proposed. No assurances can be given that the Proposed Amendments will become law. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;This
summary is not exhaustive of all possible federal income tax considerations and does not take into account or anticipate any changes in law, administrative policy or assessing
practice, whether by legislative, governmental or judicial action, other than the Proposed Amendments. This summary does not deal with foreign, provincial or territorial income tax considerations,
which may differ from the Canadian federal income tax considerations described below. This summary does not address the deductibility of interest on any funds borrowed by an investor to purchase

any capital gain realized on a disposition or deemed disposition of Common Shares, unless the Common Share is or is deemed to be "taxable Canadian property" (as defined in the Tax Act) to the
Non-Resident Shareholder at the time of disposition and the Non-Resident Shareholder is not entitled to relief under an applicable income tax convention or treaty between Canada and the country in
which the Non-Resident Shareholder is resident. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Generally,
and provided that a particular Common Share is listed on a designated stock exchange (as defined in the Tax Act) at the time of disposition, which currently includes the TSX,
such Common Share owned by a Non-Resident Shareholder will not be taxable Canadian property of the Non-Resident Shareholder at the time of disposition unless, at any time during the 60-month period

obligations of the Underwriters under the underwriting agreement are several and may be terminated at their discretion upon the occurrence of certain stated events. Such events
include, but are not limited to (i)&nbsp;trading generally being suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, Nasdaq or the TSX, (ii)&nbsp;the
suspension of trading of our securities on Nasdaq or the TSX, (iii)&nbsp;any material disruption in securities settlement, payment or clearance services in the United States or Canada,
(iv)&nbsp;any moratorium on commercial banking activities declared by federal (U.S. or Canadian), Canadian provincial or New York State authorities, or (v)&nbsp;any outbreak or escalation of
hostilities, or any change in financial markets, currency exchange rates or controls or any calamity or crisis that, in the Underwriters' judgement, is material and adverse and which makes it
impracticable or inadvisable to proceed with the offer, sale and delivery of the Offered Shares on the terms and in the manner contemplated in the Prospectus. The Underwriters are, however, obligated
to take up and pay for all of the Offered Shares if any of the Offered Shares are purchased under the underwriting agreement. However, the Underwriters are not required to take up or pay for the
shares covered by the Underwriters' Over-Allotment Option. If an Underwriter defaults, the underwriting agreement provides that the purchase commitments of the non-defaulting Underwriters may be
increased. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Offering is being made concurrently in the United States and in each of the provinces of Canada, except Quebec, pursuant to the U.S./Canada Multijurisdictional Disclosure System (the
"</FONT><FONT SIZE=2><B>MJDS</B></FONT><FONT SIZE=2>") implemented by the securities regulatory authorities in the United States and Canada. The Offered Shares will be offered in the United States
and Canada through the Underwriters either directly or through their respective U.S. or Canadian broker dealer affiliates or agents. </FONT></P>


<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;William
Blair &amp; Company, L.L.C. is not registered to sell securities in any Canadian jurisdiction and accordingly, will only sell Offered Shares outside of Canada. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Underwriters are offering the Offered Shares subject to their acceptance of the shares from us and subject to prior sale. The underwriting agreement provides that the obligations of
the several Underwriters to pay for and accept delivery of the Offered Shares are subject to the approval of certain legal matters by their Canadian and U.S. counsel and to certain other conditions. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Underwriters initially propose to offer part of the Offered Shares directly to the public at the offering price listed on the cover page of this Prospectus Supplement and part to
certain dealers at a price that represents a concession not in excess of US$0.69225 a share under the public offering price. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>After the initial offering of the Offered Shares, the offering price and other selling terms may from time to time be varied by the representatives. In all such cases, the
compensation realized by the Underwriters will be decreased by the amount that the aggregate price paid by the purchasers for the Common Shares is less than the gross proceeds paid to us by the
Underwriters. The offering of the Offered Shares by the Underwriters is subject to receipt and acceptance and subject to the Underwriters' right to reject any order in whole or in part. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We

any, made in connection with the Offering. To the extent the option is exercised, each Underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the
Additional Shares as the number listed next to the Underwriter's name in the preceding table bears to the total number of Offered Shares listed next to the names of all Underwriters in the preceding
table. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Subscriptions
for Offered Shares will be received subject to rejection or allotment in whole or in part and the Underwriters reserve the right to close the subscription books at any time
without notice. It is expected that the closing of the Offering will occur on or about June&nbsp;10, 2019, or such other date as we
and the Underwriters may agree, but in any event no later than June&nbsp;17, 2019. The Offered Shares will be issued in the form of one or more global certificates registered in the name of The
Depository Trust Company ("</FONT><FONT SIZE=2><B>DTC</B></FONT><FONT SIZE=2>"), New York, New York, or its nominee. We refer to this form as "book-entry" settlement. DTC will keep a computerized
record of its participants (for example, your broker) whose clients have purchased the Offered Shares. The participant will then keep a record of its clients who purchased the Offered Shares. A global
security may not be transferred, except that DTC, its nominees and their successors may transfer an entire global security to one another. We will treat DTC's nominee as the owner of the Offered
Shares for all purposes. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Under
book-entry settlement, we will not issue certificates to individual holders of the Offered shares. Beneficial interests in global securities will be shown on, and transfers of
global securities will be made only through, records maintained by DTC and its participants, including CDS Clearing and Depository Services&nbsp;Inc. If an individual holder wants to obtain a
physical certificate, the individual holder would request the same through its broker/investment firm and the securities are withdrawn from the amount credited on our books and records to the nominee
of DTC and re-registered into the investor's name, which in many cases, will cost the individual holder a fee. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;In
order to facilitate this Offering, the Underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Common Shares. Specifically, the
Underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the
number of shares available for purchase by the Underwriters under the Over-Allotment Option. The Underwriters can close out a covered short sale by exercising the Over-Allotment Option or purchasing
shares in the open market. In determining the source of shares to close out a covered short sale, the Underwriters will consider, among other things, the open market price of shares compared to the
price available under the underwriter's Over-Allotment Option. The Underwriters may also sell shares in excess of the Over-Allotment Option, creating a naked short position. The Underwriters must
close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the Underwriters are concerned that there may be downward pressure on
the price of the Common Shares in the open market after pricing that could adversely affect investors who purchase in this Offering. As an additional means of facilitating this offering, the
Underwriters may bid for, and purchase, Common Shares in the open market to stabilize the price of the Common Shares. The Underwriters may also impose a penalty bid. Penalty bids permit the
Underwriters to reclaim a selling concession from a syndicate member when the Underwriters repurchase shares originally sold by that syndicate member in order to cover short positions or make
stabilizing purchases. These activities may raise or maintain the market price of the Common Shares above independent market levels or prevent or retard a decline in the market price of the Common
Shares. The Underwriters are not required to engage in these activities and may end any of these activities at any time. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The
Underwriters may not, throughout the period of distribution, bid for or purchase our Common Shares. The foregoing restriction is subject to certain exemptions, as long as the bid or
purchase is not engaged in for the purpose of creating actual or apparent active trading in, or raising the price of, the Common Shares. These exceptions include a bid or purchase permitted under the
Universal Market Integrity Rules administered by the Investment Industry Regulatory Organization of Canada relating to market stabilization and passive market-making activities and a bid or purchase
made for and on behalf of a customer where the order was not solicited during the period of distribution. </FONT></P>

a Canadian chartered bank that has provided to us a US$350&nbsp;million revolving operating credit facility. Consequently, we may be considered a "connected issuer" of RBC&nbsp;Capital Markets,
Scotia, BMO and CIBC Capital Markets under applicable Canadian securities laws. As at April&nbsp;30, 2019, approximately $242.7&nbsp;million was drawn down under Credit Facility. We are in
material compliance with the terms of the agreement governing the Credit Facility. The Lenders have not waived any material breach of the agreement governing the Credit Facility since its execution.
The Credit Facility is secured by a first charge over substantially all of our assets. Our financial position has remained materially unchanged since entering into the agreement governing the Credit
Facility. The value of certain of the security underlying the agreement governing the Credit Facility may fluctuate from time to time based on various factors, including changes in the market price,
ongoing operations and business prospects of our investees. </FONT></P>

decision to issue the Offered Shares and the determination of the terms of the Offering were made through negotiation between us and the Underwriters. The Lenders did not have any
involvement in such decision or determination although such Lenders may be advised of the Offering and the terms thereof. As a consequence of the Offering, each of such Underwriters will receive its
proportionate share of the Underwriters' fee. Proceeds from the sale of Offered Shares will, among other things, be used to reduce indebtedness which we have with the Lenders. See

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;We use technology and networks to simplify complex business processes. We are primarily focused on logistics and supply chain management
business processes. Our solutions are predominantly cloud-based and are focused on improving the productivity, performance and security of logistics-intensive businesses. Customers use our modular,
software-as-a-service and data solutions to route, schedule, track and measure delivery resources; plan, allocate and execute shipments; rate, audit and pay transportation invoices; access and analyze
global trade data; research and perform trade tariff and duty calculations; file customs and security documents for imports and exports; and complete numerous other logistics processes by
participating in a large, collaborative multi-modal logistics community. Our pricing model provides our customers with flexibility in purchasing our solutions either on a subscription, transactional
or perpetual license basis. Our primary focus is on serving transportation providers (air, ocean and truck modes), logistics service providers (including third-party logistics providers, freight
forwarders and customs brokers) and distribution intensive companies for which logistics is either a key or a defining part of their own product or service offering, or for which our solutions can
provide an opportunity to reduce costs, improve service levels, or support growth by optimizing the use of assets and information. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Consistent
with past practice and in the normal course, the Company may have outstanding non-binding letters of intent and/or conditional agreements or may otherwise be engaged in
discussions with respect to possible acquisitions and/or investments which may or may not be material. However, there can be no assurance that any of these letters, agreements and/or discussions will
result in an acquisition or investment and, if they do, what the final terms or timing of any acquisition or investment would be. The Company expects to continue to actively pursue acquisition and
investment opportunities during the period that this Prospectus remains valid. </FONT></P>

<P style="font-family:times;"><FONT SIZE=2>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;The Company's authorized share capital consists of an unlimited number of Common Shares. As of the date of this Prospectus, 76,814,800 Common

and/or the Selling Securityholder(s)); (ii)&nbsp;the number of Common Shares offered; (iii)&nbsp;the offering price (in the event that the offering is a fixed price distribution); (iv)&nbsp;the

the provinces, the securities legislation further provides a purchaser with remedies for rescission or, in some jurisdictions, revision of the price or damages if the prospectus and any amendment
contains a misrepresentation or is not delivered to the purchaser, provided that the remedies for rescission, revision of the price or damages are exercised by the purchaser within the time limit
prescribed by the securities legislation of the purchaser's province. The purchaser should refer to any applicable provisions of the securities legislation of the purchaser's province for the

incidental to the applicable offering as a whole) or convertible or exchangeable Debt Securities (or Units comprised partly thereof) will have a contractual right of rescission against the Company in
respect of the conversion, exchange or exercise of the convertible or exchangeable Preferred Share, Subscription Receipt, Warrant or the convertible or exchangeable Debt Security. The contractual

exchangeable or exercisable security upon surrender of the underlying securities acquired thereby, in the event that this Prospectus (as supplemented or amended) contains a misrepresentation, provided

an offering of convertible or exchangeable Preferred Shares, Subscription Receipts, Warrants or convertible or exchangeable Debt Securities (or Units comprised partly thereof),
investors are cautioned that the statutory right of action for damages for a misrepresentation contained in the prospectus is limited, in certain provincial securities legislation, to the price at
which convertible or exchangeable Preferred Shares, Subscription Receipts, Warrants or convertible or exchangeable Debt Securities (or Units comprised partly thereof) are offered to the public under
the prospectus offering. This means that, under the securities legislation of certain provinces, if the purchaser pays additional amounts upon the conversion, exchange or exercise of the security,
those amounts may not be recoverable under the statutory right of action for damages that applies in those provinces. The purchaser should refer to any applicable provisions of the securities
legislation of the purchaser's province for the particulars of this right of action for damages or consult with a legal adviser. </FONT></P>
