2.Corporate Structure



We were incorporated on June 10, 2009 under the Canada Business
Corporations Act, under the name “7188501 Canada Inc.” We changed our name to “Hydrogenics Corporation-Corporation
Hydrogenique” on October 27, 2009 in connection with the transaction involving Algonquin Power Income Fund (“APIF”),
as described further below under “APIF Transaction.”



Old Hydrogenics was founded in 1988 under the name “Traduction
Militech Translation Inc.” It subsequently changed its name to “Société Hydrogenique Incorporée-Hydrogenics
Corporation Incorporated”. From 1990 to August 1995, Société Hydrogenique Incorporée-Hydrogenics
Corporation Incorporated did not actively carry on business. In August 1995, we commenced our fuel cell technology development
business, and in 2000, changed our name to Hydrogenics Corporation - Corporation Hydrogenique. Until October 27, 2009, we
were a wholly owned subsidiary of Old Hydrogenics.



We are a globally recognized developer and provider of hydrogen
generation and fuel cell products. We conduct our business through the following business units: (i) OnSite Generation, which
focuses on hydrogen generation products for renewable energy, industrial and transportation customers; and (ii) Power Systems,
which focuses on fuel cell products for original equipment manufacturers, or OEMs, systems integrators and end users for stationary
applications, including backup power, and motive applications, such as forklift trucks. In November 2007, we announced we
were exiting the fuel cell test products, design, development and manufacturing business that was conducted through our test systems
business unit (“Test Systems”).



Our business units are supported by a corporate services group providing
finance, insurance, investor relations, communications, treasury, human resources, strategic planning, compliance, and other administrative
services.



Our principal executive offices are located at 220 Admiral Boulevard,
Mississauga, Ontario, Canada L5T 2N6. Our telephone number is (905) 361-3660. Our agent for service in the United States for any
actions relating to our common shares is CT Corporation System, 111 Eighth Avenue, New York, New York 10011, (212) 894-8400.



As of March 9, 2016, we beneficially owned, directly or indirectly,
100% of the voting and non-voting securities of the material subsidiaries listed below.

Where applicable, corporate and other activities are reported separately
as Corporate and Other. This is the provision of corporate services and administrative support. At December 31, 2015, our Corporate
and Other activities had five full-time employees.



Our business, as at March 9, 2016, is summarized below:



OnSite Generation



Our OnSite Generation business segment, is based on water electrolysis
technology which involves the decomposition of water into oxygen (O2) and hydrogen gas (H2) by passing an electric current through
a liquid electrolyte or a polymer electrolyte membrane (“PEM”). The resultant hydrogen gas is then captured and used
for industrial gas applications, hydrogen fueling applications, and is used to store renewable and surplus energy in the form of
hydrogen gas. Our HySTAT® branded electrolyzer products are based on 60 years of hydrogen experience, meet international standards,
such as ASME, CE, Rostechnadzor and UL, and are certified ISO 9001 from design to delivery. We configure our HySTAT® products
for both indoor and outdoor applications and tailor our products to accommodate various hydrogen gas requirements.



The worldwide market for hydrogen, which includes the merchant gas
market for hydrogen, is estimated at $5 billion annually, and is served by industrial gas companies as well as on-site hydrogen
generated by products manufactured by companies such as ours. We believe the annual market for on-site hydrogen generation equipment
is approximately $100 million to $200 million. We believe the size of the addressable market for on-site hydrogen generation equipment
could more than double if energy storage and electrolysis based hydrogen fueling stations gain widespread acceptance.



Our OnSite Generation products are sold to leading merchant gas
companies, such as Air Liquide and Linde Gas and end-users requiring high purity hydrogen produced on-site for industrial applications.
We also sell and service products for progressive oil and gas companies, such as Shell Hydrogen, requiring hydrogen fueling stations
for transportation applications. Recently, an increase in orders and interest for fueling stations in Europe and elsewhere, has
signaled what we believe could be a major increase in the size of this market. During the past year, we have also witnessed an
increase in interest and orders for our small, medium and large scale energy storage products, which also service the need for
ancillary electrical power services, such as grid balancing and load profiling. While this area is heavily dependent on public
funding initiatives, particularly in Europe, it continues to present compelling growth opportunities. In 2009, we began to sell
our products to leading electric power utilities to satisfy the need for renewable energy storage.



The business objectives for our OnSite Generation group are to:
(i) continue to pursue opportunities for customers to convert otherwise wasted renewable and other excess energy, such as wind,
solar or excess baseload energy, into hydrogen; (ii) further expand into traditional markets, such as Eastern Europe (including
Russia), Asia and the Middle East; (iii) grow our fueling station business; (iv) further increase the gross margins of existing
product lines by improving our procurement and manufacturing processes; (v) reduce the cost of ownership of our products through
design and technology improvement; and (vi) further increase the reliability and durability of our products to exceed the expectations
of our customers and improve the performance of our applications.



Our OnSite Generation business competes with merchant gas companies,
such as Air Liquide and Linde Gas which, in addition to being customers, operate large scale centralized hydrogen production plants
and are providers of alternative on-site hydrogen generation products using steam methane reforming (“SMR”) technology
or other electrolysis technology. We compete on performance, reliability and cost and believe we are well positioned in situations
where there is a need for high purity hydrogen manufactured on-site.



Hydrogenics is pioneering Power-to-Gas, an innovative energy conversion
and storage solution using electrolysis. Power-to-Gas is the three-step process of integrating renewable sources of generation
by load-following, converting the surplus electricity to hydrogen or renewable gas, and leveraging the existing natural gas infrastructure
for seasonal storage. An electrolyzer provides the rapid, dynamic response to the Independent System Operator’s signals to
accurately load-follow the intermittent generation pattern of renewable sources such as wind turbines. The hydrogen produced is
injected into the natural gas system and can be intermingled with natural gas and thus additional storage vessels are not needed.
Surplus electricity can be stored for consecutive days or even consecutive weeks without the need to discharge; it is a seasonal
storage capability. This energy storage solution bridges the power grid and the gas grid to unlock new options. It enhances the
flexibility of managing the power grid and provides the means to capitalize on the vast potential of alternative sources of generation
to produce a local source of renewable gas to de-carbonize the gas system. Hydrogenics is working with global energy utilities
such as E.ON and Enbridge to commercialize Power-to-Gas energy storage globally.

We also are promoting electrolysis in hydrogen fueling stations
as possible Power-to-Gas solutions at a distributed storage level. The electrolyzer can be used to generate hydrogen during periods
of surplus energy levels, thus absorbing the excess energy at lower cost to generate hydrogen. This hydrogen is then stored at
site and can be used to fuel hydrogen cars and busses. If the surplus power is generated from renewable energy sources such as
wind and solar, the potential exists for a completely green solution as hydrogen fuel cell vehicles emissions are only water vapor.



Power Systems



Our Power Systems business segment is based on PEM fuel cell technology,
which transforms chemical energy liberated during the electrochemical reaction of hydrogen and oxygen into electrical energy. Our
HyPM® branded fuel cell products are based on our extensive track record of on-bench testing and real-time deployments across
a wide range of stationary and motive power profiles. We configure our HyPM® products into multiple electrical power outputs
ranging from 1 kilowatt to 1 megawatt (“MW”) with ease of integration, high reliability and operating efficiency, delivered
from a highly compact area.



Our target markets include backup power for telecom and data centre
installations and motive power applications, such as buses, trucks and utility vehicles. The military, historically an early technology
adopter, is a specialized market for our innovative fuel cell based products. The worldwide market for data centre backup power
is estimated to be in excess of $6 billion and the market for telecom backup power is estimated to be $2 to $3 billion in the United
States alone, based on a complete displacement of existing products serving this market.



Our Power Systems products are sold to leading Original Equipment
Manufacturers (“OEMs”), to provide backup power applications for telecom installations and vehicle and other integrators
for motive power, direct current (“DC”) and alternative current (“AC”) backup. Additionally, our products
are sold for prototype field tests intended to be direct replacements for traditional lead-acid battery packs for motive applications.
We also sell our Power systems in stationary power applications such as that employed by our Kolon-Hydrogenics joint venture in
South Korea. Finally, we also sell our Power Systems products to the military, aerospace and other early adopters of emerging technologies.



The business objectives for our Power Systems group are to: (i)
offer a standard fuel cell platform for many markets, thereby enabling ease of manufacturing and reduced development spending;
(ii) achieve further market penetration in the backup power and motive power markets by tailoring our HyPM® fuel cell products
to meet market specific requirements, including price, performance and features; (iii) reduce product cost; (iv) invest in sales
and market development activities in the backup power and motive power markets; (v) continue to target the military and other early
adopters of emerging technologies as a bridge to future commercial markets; and (vi) secure the requisite people and processes
to align our anticipated growth plans with our resources and capabilities.



Our Power Systems business competes with several well-established
battery and internal combustion engine companies in addition to several other fuel cell companies. We compete on relative price/performance
and design innovation. In the backup power market, we believe our HyPM® systems have an advantage over batteries and internal
combustion engines for customers seeking extended run requirements, by offering more reliable and economical performance. In motive
power markets, we believe our HyPM® products are well positioned against diesel generation and lead-acid batteries by offering
increased productivity and lower operational costs.



There are four types of fuel cells other than PEM fuel cells that
are generally considered to have possible commercial applications, including phosphoric acid fuel cells, molten carbonate fuel
cells, solid oxide fuel cells and alkaline fuel cells. Each of these fuel cell technologies differs in their component materials
and operating characteristics. While all fuel cell types may have potential environmental and efficiency advantages over traditional
power sources, we believe PEM fuel cells can be manufactured less expensively and are more efficient and more practical in small-scale
stationary and motive power applications. Further, most automotive companies have selected PEM technology for fuel cell powered
automobiles. We expect this will help establish a stronger industry around PEM technology and may result in a lower cost, as compared
to the other fuel cell technologies.

History



From inception through to the end of 2000, our revenues were predominantly
derived from selling test products and related diagnostic equipment, with limited sales of fuel cell products and engineering services,
principally under military and government contracts. In November 2000, we completed our initial public offering of common shares
generating net proceeds of $84 million and listed our common shares on the Toronto Stock Exchange (“TSX”) and the Nasdaq
Global Market (“Nasdaq”). These funds, combined with our expertise in the fuel cell testing business, provided the
platform for advancing the development of our fuel cell power products. In 2001, we began to expand the sale of our fuel cell products
and of our integration services.



In January 2003, we acquired Greenlight Power Technologies, Inc.,
our principal competitor in the fuel cell test equipment business, for $20 million, satisfied by approximately $2.3 million of
cash and 4.2 million common shares. Subsequent to our acquisition, we consolidated our fuel cell test businesses in Burnaby, British
Columbia allowing us to accelerate our fuel cell development activities in Mississauga, Ontario.



In a February 2004 offering, we issued a total of 11.4 million common
shares for net proceeds of $61.6 million including the over-allotment option.



In January 2005, we acquired Stuart Energy, a recognized leader
in onsite hydrogen generation systems for industrial, transportation and energy markets, for $129 million. We satisfied the purchase
price by issuing approximately 27 million shares. This acquisition diversified our product portfolio, provided us with a world
class customer base including Air Liquide, Air Products, Cheung Kong Infrastructure, Chevron, Ford, General Motors, Linde, Shell
Hydrogen and Toyota, strengthened our European presence, and augmented our management team and employee base. On completion of
our acquisition, we carried out a comprehensive integration program achieving annualized cost savings exceeding $10 million.



In March 2007, we implemented a restructuring and streamlining of
our operations to reduce its overall cost structure. Subsequently, in November 2007, further cost reduction initiatives were undertaken.
These initiatives resulted in a workforce reduction of approximately 100 full-time equivalent positions. The Company incurred approximately
$4.1 million pre-tax charges in 2007 in connection with these initiatives.



In November 2007, after conducting an extensive evaluation of the
opportunities for our fuel cell test products design, development and manufacturing business and canvassing all opportunities,
our Board of Directors approved plans for an orderly windup of the business which is based in our Burnaby, British Columbia facility.



In 2008, we further streamlined our operations, which resulted in
a workforce reduction of approximately 25 full-time equivalent positions representing approximately $1.3 million of annual payroll
costs.



On June 11, 2009, we, Old Hydrogenics, the Board of Trustees of
Algonquin Power Income Fund (“APIF”) and APIF’s manager, Algonquin Power Management Inc., agreed on the terms
of a series of transactions (collectively, the “APIF Transaction”) and agreements, pursuant to which Old Hydrogenics
agreed to transfer its entire business and operations to us, including all assets, liabilities, directors, management and employees,
but excluding its tax attributes. Concurrently, the APIF Transaction enabled unitholders of APIF to continue to hold their interest
in APIF as shareholders of Old Hydrogenics, which was renamed Algonquin Power & Utilities Corp. (“APUC”), a publicly
traded Canadian corporation. APUC has the ability to make efficient use of our accumulated tax attributes in the continued execution
of APIF’s business plans. Under the APIF Transaction, our shareholders had their common shares in the capital of Old Hydrogenics
redeemed for our common shares on a one-for-one basis. At the same time APIF unitholders exchanged their units for APUC common
shares.



As a result of completion of the APIF Transaction on October 27,
2009, unitholders of APIF did not retain any interest in the business of the Corporation nor did the Corporation’s shareholders
retain any interest in the business of APIF. We have continued to carry on the hydrogen generation and fuel cell business as a
public entity with all of the assets (including the intellectual property), except for certain tax assets, of our predecessor prior
to the APIF Transaction.

During 2010, we completed an offering of common shares and warrants
for gross cash proceeds of $5.0 million before placement agent’s fees and other offering expenses.



On August 9, 2010, we entered into a subscription agreement (the
“Agreement”) with CommScope Inc. of North Carolina, a subsidiary of CommScope wherein CommScope will purchase from
us common shares in four tranches, up to a maximum of 2,186,906 shares for a maximum aggregate purchase price of $8.5 million,
subject to achieving certain product development milestones. During 2010, we closed the first two tranches under the terms of the
Agreement for gross cash proceeds of $4.0 million. We incurred issuance costs of $0.2 million in connection with the issuance of
the first and second tranches. During 2011, we completed the final two tranches of a private placement offering of common shares
with CommScope for gross cash proceeds of $4.5 million.



In September 2011, the Corporation entered into an agreement with
the Province of Ontario’s Ministry of Economic Development, Strategic Jobs and Investment Fund
for a low-interest rate loan of up to CA$6.0 million.



During 2012, we completed a private placement offering of common
shares with Enbridge for gross cash proceeds of $5.0 million.



In 2013, we completed an offering of common shares for gross cash
proceeds of $6.9 million, including an overallotment.



In 2014, we completed an offering of common shares for gross cash
proceeds of $15 million. Also in 2014 we entered into a joint venture with Kolon Water and Energy, a South Korean company to develop
stationary power applications using fuel cell technology for the Korean market. Hydrogenics owns 49% of the joint venture and contributed
2.45 billion Korean Won to the transaction (approximately $2.3 million).



During 2015, we completed an offering of common shares and warrants
for gross cash proceeds of $19.0 million before placement agent’s fees and other offering expenses.



Industry Trends



A discussion of industry trends, by its nature, necessarily contains
certain forward-looking statements.  Forward-looking statements require us to make assumptions and are subject to inherent
risks and uncertainties that could cause actual results or events to differ materially from current expectations.  Please
refer to the caution regarding Forward-looking statements contained in the “Forward-looking Statements” section on
page 1 and the “Risk Factors” section beginning on page 21 for a discussion of such risks and uncertainties and the
material factors and assumptions related to the statements set forth in this section.



We anticipate our business will continue to benefit from several
broad trends including: (i) increased government legislation and programs worldwide promoting alternative energy sources such as
synthetic fuels, including hydrogen; (ii) increased awareness of the adverse impact of fossil fuels on our climate and environment;
and (iii) the need for industrialized economies to access alternative sources of energy to reduce fossil fuel dependency. 
We anticipate these trends will continue and intensify in the future, allowing the benefits of hydrogen to be further demonstrated
in numerous applications. In particular, hydrogen can be generated universally from renewable power sources such as hydroelectric,
geothermal, solar and wind or from low-emission sources such as biomass and nuclear.  These industry trends are discussed
below.



Increased government legislation and programs worldwide promoting
alternative energy sources including hydrogen. In recent years, numerous governments have introduced legislation to promote
and develop the use of hydrogen in energy applications as a partial response to the risks and adverse effects associated with fossil
fuels.  We anticipate this interest will accelerate over time.  Recent government legislation has been proposed or passed
in many jurisdictions to support renewable energy initiatives.



The European Union has set a series of demanding climate and energy
targets to be met by 2020, known as the "20-20-20" targets. The targets are i) a reduction in EU greenhouse gas emissions
of at least 20% below 1990 levels ii) to have 20% of EU energy consumption to come from renewable resources and iii) a 20% reduction
in primary energy use compared with projected levels, to be achieved by improving energy efficiency. One of the significant results
of these targets are that a significant amount of vehicles using diesel and gasoline fuels in the road transportation sector will
be replaced with vehicles that use natural gas and hydrogen by 2020. European efforts include the European Commission (“EC”)
establishing a platform to bring hydrogen and fuel cells to market and a proposed Joint Technology Initiative for public-private
partnership.  The EC’s 7th Framework Programme is currently providing $1.2 billion over five years for hydrogen and
fuel cell initiatives under the European Hydrogen and Fuel Cell Technology Platform.  In 2016, 117.5M euros of funding is
provided. There has been an increased commitment from German’s H2Mobility consortia to put the needed hydrogen filling stations
in place to meet these targets. There have also been EU early policy statements targeting hydrogen filling stations every 300 km
to ensure suitable coverage for the fuel cell vehicles intended to be brought to market.

Additionally, several Asian countries are responding to environmental,
energy, security and socio-economic concerns by introducing legislation and initiatives to promote hydrogen and fuel cell technologies. 
Japan, Korea, India and China continue to invest significantly in the development and commercialization of hydrogen and fuel cells.



Finally, the global commitment to combating climate change was memorialized
with definitive greenhouse gas reduction targets at the United Nations Climate Change Conference (COP21) held in the fall of 2015.
Hydrogenics should benefit from these targets as countries look to invest into clean technology applications.



Finally, Hydrogenics is pioneering Power-to-Gas, an innovative energy
conversion and storage solution using electrolysis, which will assist the government to reach their goals on the climate and energy
targets.  Power-to-Gas helps the grid operator integrate renewable sources of generation and converts this power into hydrogen
using electrolysis. The hydrogen can be used as a renewable fuel or renewable gas in different applications as follows: hydrogen
for FCEVs (fuel cell electric vehicles), direct injection into the natural gas grid, methanation for synthetic natural gas, or
as a renewable fuel stock for refineries or other industrial processes. Power-to-Gas is an energy storage solution which bridges
the electricity sector with the much largernatural gas and transport energy sectors using hydrogen as decarbonized gas or liquid
fuels. It is a scalable solution with expected commercial deployments in the 15 to 50 MW range. Hydrogenics is currently working
with leading utilities worldwide on demonstration projects.



Increased awareness of the adverse impact of fossil fuels on
our climate, environment and air quality.Governments worldwide continue to enact legislation aimed at curtailing the
impact of fossil fuels on the environment. In addition to well established protocols such as COP21, the Kyoto Accord and the Canada
Clean Air Act there have been recent initiatives in various jurisdictions which continue to reinforce that the impact of fossil
fuels on the environment must be reduced. De-carbonization for urban transit remains a high priority in many urban centers around
the world. Certain urban centers, such as Beijing are recording their highest ever levels of pollutants emphasizing the growing
awareness of the adverse impact of fossil fuels. In 2012 the EU brought out its airline carbon tax and enacted legislation requiring
airlines to pay a carbon emissions charge for all flights landing in the EU based on the amount of carbon emitted



The need for industrialized economies to access alternative sources
of energy to reduce their dependency on fossil fuels. Many industrialized nations, including some of the fastest growing
economies, import most, or all, of the fossil fuels consumed. This creates a dependency on external sources and exposes them to
significant trade imbalances. In addition, the earthquake and resulting tsunami in Japan has caused many governments to consider
reducing dependency on nuclear power plants and consider alternative power sources such as hydrogen. The growing concern over volatile
climate occurrences often attributed to climate change is driving the desire for longer backup power requirements. While conventional
backup systems are adequate for several hours of backup, the world has seen an increase of incidences requiring the ability to
maintain power over the course of several days, and we believe hydrogen fuel cell power is ideal for such applications.



For stationary power, in the United States alone, approximately 400,000 MWs of new electricity generating
capacity is forecast to be needed by 2020 to meet growing demand and to replace retiring generating units.  The existing electricity
transmission and distribution grid in the United States is overburdened in many regions.  By locating power generation products
close to where the power is used, known as distributed generation, it is possible to bypass the overloaded transmission and distribution
grid.  Hydrogen and fuel cell technologies are well suited to a distributed generation model thereby providing an emerging
opportunity for hydrogen fuel cells and hydrogen powered internal combustion engines to provide stationary generating capacity.



China also has growing concerns about air quality, energy supply
and security, which is leading it to pursue initiatives promoting hydrogen and energy efficiency programs especially in urban transport.
Further, as the introduction of automobiles and transit vehicles continues to accelerate in China, such dependency on fossil fuels
may become increasingly unsustainable, creating an opportunity for hydrogen and fuel cells.



7






The above noted factors have led to increased interest from progressive electric power
and gas utilities throughout the world seeking a robust and cost-effective solution for renewable and excess energy storage and
the provision of ancillary services such as grid balancing and load following.



Our Strategy



Our strategy is to develop electrolyzer and fuel cell products for
sale to OEMs, electric utilities, gas utilities, merchant gas companies and end-users requiring highly reliable products offered
at competitive prices. We believe our success will be substantially predicated on the following factors:





Increasing Market Penetration



At December 31, 2015, we had 16 full-time staff employed in sales
functions. Our senior management team is also actively involved in sales initiatives, including maintaining close contact with
our more significant customers. In the year, significant efforts were made in the sales function; including repositioning of responsibilities
to permit dedicated leadership for the sales function, obtaining detailed assessments of markets, and leveraging our strategic
relationships with companies such as Enbridge and Kolon.



2015 was a strong year for product launches. In Power Systems, we
launched a 1 MW stationary baseload power system with our Korean partner Kolon Water and Energy. The unit began commercial operation
in October 2015 at a refinery site in Korea. On the mobility front Hydrogenics signed a 10 year contract to develop and supply
hydrogen fuel cell propulsion systems for Alstom Transport for passenger rail in Europe,  In Q4 the first prototype was shipped
to Alstom Transport to begin early trials.  In On Site Generation, our customer E.ON, a major global energy and gas company
headquartered in Germany, went live with our 1.5 MW unit using our newer PEM electrolyzer technology in Hamburg Germany. This energy
storage application is in addition to the 2 MW application of alkaline electrolysis that was sold in 2012.  We are now
the only company in the world to successfully launch PEM technology that can absorb a MW of energy in a single PEM stack. In addition,
Hydrogenics shipped and successfully started a 0.5 MW electrolyser for Kurion, an environmental company specializing in the cleanup
of radioactive contaminated water.  Kurion has been a key player in the decontamination of the Fukushima plant in Japan. 
The electrolyser is part of a pilot plant that if successful could be the technology selected by Japan to remediate the expanding
volume of tritiated water at Fukushima.



Additionally, we have developed or maintained relationships with
third parties we believe are well positioned in our relevant markets to identify new market opportunities for our products. In
the industrial gas market, these third parties include leading merchant gas companies, such as Air Liquide and Linde Gas. In the
energy storage market, it is leveraging our strategic relationship with Enbridge as well as our global contacts with other large
utilities, gas companies and regulators



We are also noting increased success in partnering with companies
to develop hydrogen fueling stations using our electrolysis technology as automobile manufacturers begin to roll out hydrogen fuel
cell vehicles at commercial production levels (principally for the European, Asian and California markets).





Future Markets



The ongoing development of Power-to-Gas applications continues in
cooperation with global partners such as Enbridge in Canada and E.ON in Germany. Power-to-Gas enhances the flexibility of managing
the power grid andprovides the means to capitalize on the vast potential of alternative sources of generation to produce
a local source of renewable gas to de-carbonize the gas system. As the existing fleet of Combined Cycle Gas Turbine (“CCGT”)
generators contract for this renewable gas, the clean but intermittent characteristics of renewable generation are transformed
into a dispatchable renewable resource when and where it is needed. Since the hydrogen or substitute natural gas is stored in the
natural gas system, the discharge of stored energy is not restricted to the site of charging like other technologies such as pumped
hydro storage and CAES (Compressed Air Energy Storage). As a result, a Power-to-Gas plant can be optimally sited at a point of
congestion on the power grid to alleviate the problem. It is also a scalable solution, with expected commercial deployments between
5MW to 100MW. Hydrogenics is currently working with leading utilities worldwide in demonstration projects and setting the stage
for commercial-scale projects.



We also are promoting electrolysis in hydrogen fueling stations
as possible Power-to-Gas solutions at a distributed storage level. The electrolyzer can be used to generate hydrogen during periods
of surplus energy levels, thus absorbing the excess energy at lower cost to generate hydrogen. This hydrogen is then stored at
site and can be used to fuel hydrogen cars and busses. If the surplus power is generated from renewable energy sources such as
wind and solar, the potential exists for a completely green solution as hydrogen fuel cell vehicles emissions are only water vapor.

Advancing Our Product Designs



Within our OnSite Generation business segment, we remain focused
on two key areas. First, reducing the cost of our HySTAT® alkaline electrolyzer and improving its efficiency. Innovation
in the design, elimination of non-value adding components, improved component sourcing and fundamental electrochemical improvements
have all contributed to ongoing cost reduction initiatives in 2015 and beyond. We also recognize the opportunity for larger scale
energy storage installations and are continuing to develop significantly scale-up products to better meet this market opportunity.
Second, we are looking at continuing the rollout of PEM electrolysis, particularly in the area of Power-to-Gas where the PEM technology
provides a more scalable solution than alkaline electrolysis at higher power levels.



Within our Power Systems business segment, we spent much of 2015
focusing on further reducing the cost of a fully integrated fuel cell system inclusive of its components. We have achieved significant
cost reduction milestones but will continue to further improve the financial viability of the product in the marketplace by looking
at both scale (increased volume ordering from suppliers) as well as bringing components of the supply chain in-house to further
reduce production cost.





Securing Additional Capital



As at December
31, 2015, we had $24.9 million of cash, cash equivalents and restricted cash, had $21.2 million of shareholders’ equity and
$59.6 million of assets.



Historically
we have not been profitable and we do not anticipate achieving a consistent level of profitability, and hence, generate consistent
positive cash flow from operations for the next several quarters. The failure to raise sufficient funds necessary to finance future
cash requirements could adversely affect our ability to pursue our strategy and negatively affect our operations in future periods.
We are addressing this matter by maintaining contact with analysts and institutional investors to better articulate our investment
merits and are advancing discussions with possible strategic investors.



In the second
quarter of 2014, we filed a final short form base shelf prospectus with certain Canadian and US securities regulatory authorities.
The shelf prospectus will allow us to offer, from time to time over a 25-month period, up to $100 million of debt, equity and other
securities.



Our intention
was to use any net proceeds received from any offering pursuant to such shelf prospectus to fund current operations and potential
future growth opportunities, except as otherwise may be disclosed in a prospectus supplement relating to such offering.



We are not required
to offer or sell all or any portion of the securities pursuant to the shelf prospectus in the future and will only do so if we
believe market conditions warrant it.



On May 13, 2014 we entered into an underwriting agreement with Canaccord
Genuity to issue 1,000,000 common shares of the Company at an issue price of $15.00 per share. Commscope participated in this offering
as a secondary issuer and sold 500,000 of their shares, also at $15.00 per share. On May 16, 2014 the Company issued 1,000,000
shares for gross proceeds of $15 million. Net proceeds after underwriting fees and expenses were $13.5 million.



On December 11, 2015 we entered into an underwriting agreement with
Craig-Hallum Capital Group LLC to issue 2,129,031 common shares of the Company at an issue price of $7.75 per share. Craig-Hallum
Capital Group also retained an overallotment of 319,354 shares that could be issued at any time on the ensuing 30 days. On December
16, 2015 the Company issued 2,448,385 shares for gross proceeds of $18,975 inclusive of the overallotment. Net proceeds after underwriting
fees and expenses were $17,549.



Retaining and Engaging Our
Staff



At December
31, 2015, we had 174 full-time employees, the majority of who have been employed by the Corporation for several years and possess
strong technical backgrounds with extensive industry experience. We strive to maintain a high level of employee engagement by compensating
at market rates, and providing interesting and challenging work.



9






At December 31, 2015, we had sixteen full-time staff employed in
sales functions. Our senior management team is also actively involved in sales initiatives, including maintaining close contact
with our more significant customers.

market and stage of technology adoption.



Customers



Our OnSite Generation products are sold to leading merchant gas
companies such as Air Liquide and Linde Gas and end users requiring high purity hydrogen produced on-site for industrial applications. 
We also sell and service products for progressive oil and gas companies such as Shell Hydrogen requiring hydrogen fueling stations
for transportation applications. During the past year we have also witnessed an increase in interest and orders for our small,
medium and large scale energy storage products which also service the need for ancillary electrical power services such as grid
balancing and load profiling.



10






Our Power Systems products are sold to leading Original Equipment
Manufacturers (“OEMs”) such as CommScope, Inc. (“CommScope”) to provide backup power for telecom installations
and Alstom Transport for passenger rail propulsion. Supply to other integrators for mobility and other stationary applications
included AC backup and baseload power. Additionally, our products are sold for prototype field tests intended to be direct replacements
for traditional lead-acid battery packs for motive applications. We also sell our Power Systems products to the military and other
early adopters of emerging technologies.



In 2015, three customers each comprised 25% of our revenue (in 2014,
three customers each comprised 32% of our revenue). In 2015, 64% of our revenues was derived from Europe, 18% from North and South
America, 12% from Asia, and the remaining 6% were derived from other foreign jurisdictions (in 2014, these numbers were 59%, 21%,
18% and 2%, respectively). Accordingly, we have mitigated risk to any single market or adoption rate by diversifying our product
portfolio across the markets in which we operate.



We have entered into agreements with several customers to pursue
commercial opportunities, which we view as important to our success. Our key customer agreements are summarized below.



Leading Global Industrial Gas
Companies. We have previously established preferred supplier agreements with Air Liquide S.A., Air Products and Chemicals,
Inc., and Linde A.G., three of the leading global industrial gas companies. Typically, these agreements provide that for industrial
applications we will be the preferred supplier of on-site, electrolysis-based hydrogen generators to the applicable industrial
gas company. We believe these relationships represent valuable sales channels, while providing validation of our technology from
highly credible partners.



Enbridge. In April 2012,
we entered into a joint development agreement with Enbridge, the owner and operator of Canada's largest natural gas distribution
company, various North American midstream gas assets, and a leader in clean energy solutions, to jointly develop utility scale
energy storage in North America.



OEM. In October 2012, we
entered into a multi-year joint cooperation agreement with an OEM. In conjunction with the signing of the cooperation agreement,
we were awarded a $36 million contract for the supply of propulsion system equipment including integrated fuel cell power systems,
power electronic converters, associated hardware and propulsion system software. The contract includes additional equipment commitments
of $13 million as well as optional equipment and services totaling another $43 million over a 10 year period. These options will
be triggered as required for production, spare parts, warranty, and service requirements



CommScope. In August 2010,
we entered into a strategic alliance with CommScope, a global leader in infrastructure solutions for communications networks, that
calls for the development and distribution of specialized fuel cell power systems and includes an equity investment in Hydrogenics.
Under the terms of the agreement, CommScope and Hydrogenics have jointly developed next-generation power modules for telecom-related

Research and Product Development

Our research and product development team consists of approximately
44 staff, the majority of whom are located in Mississauga, Ontario, and are focused primarily on our fuel cell and PEM technology
activities. The remainder is located in Oevel, Belgium. Collectively, these individuals have many years of experience in the design
of electrolysis and fuel cell products. Our product development team combines leaders with extensive experience in their fields
with younger graduates from leading universities.



Our objective is to develop complete products rather than components
and to ensure these products are constantly improved throughout the product’s life. Our research activities are unique to
each of our business units but typically focus on the cost, performance and durability of our products. Our product development
activities commence with a market requirement document establishing the business case for the proposed product. This process involves
staff from our business development, finance, engineering and operations departments who balance the requirements of performance,
time to market, and product cost. Prototypes are often validated by lead customers such as CommScope.



We seek cost-sharing projects with various government and non-government
agencies, to offset, to the extent possible, our research and product development expenses. We currently have contribution agreements
with Natural Resources Canada and the Province of Ontario. In 2012, $3.0 million, or 54% of our research and product development
expenses, were funded by various governments. In 2013 Hydrogenics Corporation entered into a loan agreement with the Province of
Ontario’s Ministry of Economic Development and Trade, Strategic Jobs and Investment Fund for up to CA$6.0 million. In 2013
and 2014, the Corporation drew down CA $5.9 million of the loan, which is calculated based on 50% of eligible costs to a maximum
of CA $1.5 million per disbursement. The loan is a low interest rate loan, and if certain criteria are met, such as the retention
and creation of a specified number of jobs, the loan will be interest free for the first five years. In 2014, Hydrogenics Corporation
entered into a loan agreement with the Province of Ontario’s Ministry of Economic Development and Innovation, Innovation
Development Fund for up to CA$4.0 million. As of March 9, 2016, $0.3 million has been drawn on this loan. If conditions are met,
this loan is interest free and forgivable upon project completion.



Our current research and product development plans are summarized
below:



OnSite Generation. Our research
activities are focused on improving the performance and reducing the cost of our electrolyzer stacks and systems through advances
in materials, design and components. Our product development team is working on advancing the next generation of on-site hydrogen
generators by developing mega-watt (MW) scale PEM electrolyzer systems utilizing Hydrogenics’ MW scale PEM electrolyzer stack
technology.  These new products are designed to store large amounts of renewable or other excess energy as hydrogen, thereby
helping to address large scale grid energy storage problems, for Power-to-Gas applications and for vehicle refueling.



Power Systems.  Since
the late 90’s, research and development has focused on polymer electrolyte fuel cells (PEMFC) for hydrogen and reformate
applications.  Our fuel cell research activities are concentrated on lowering the cost, improving the fuel efficiency, product
lifetime and reducing system complexity. Activities range from focused fundamental materials research to stack and system development
and testing.  At the stack level, our research and development team is working on developing our next generation of stack
technology which is expected to significantly increase power density and lower costs.  At the fuel cell engine or module
level, we continue to expand our product line by leveraging our proven stack and system architecture while continuing to lower
cost on existing products in order to meet market specific cost requirements.





Intellectual Property

We protect our intellectual property by means of a combination
of patent protection, copyrights, trademarks, trade secrets, licences, non-disclosure agreements and contractual provisions. We
generally enter into non-disclosure and confidentiality agreements with each of our employees, consultants and third parties that
have access to our proprietary technology. We currently hold 122 patents in a variety of jurisdictions and have 48 patent applications
pending. Additionally, we enter into commercial licences and cross-licences to access third party intellectual property.



12






We believe our intellectual property provides us a strong competitive
advantage and represents a significant barrier to entry into our industry for potential competitors.  As part of our patent
portfolio, we maintain a collection of innovative energy storage patents with broad and exclusive rights concerning the use of
excess electrical power to produce hydrogen from water while simultaneously providing electric grid stabilization services. 
We believe these patents place Hydrogenics in the strongest possible position to build our company over the long-term and will
continue to strengthen our efforts as electric grid operators look to hydrogen as an important strategy for utility-scale energy
storage.



We typically retain sole ownership of intellectual property developed
by us. In certain situations we provide for shared intellectual property rights. For example, with General Motors, we have a non-exclusive,
royalty free licence to use certain of General Motors’ proprietary fuel cell stack intellectual property in certain applications
and markets. We have these rights in perpetuity, including subsequent improvements to the licensed technology.



Given the relative early stages of our industry, our intellectual
property is and will continue to be important in providing differentiated products to customers.



Manufacturing

The majority of our manufacturing services, including parts procurement,
kitting, assembly and repair, are carried out in-house at our respective business unit manufacturing facilities. We also perform
certain manufacturing-related functions in-house, including manufacturing engineering and the development of manufacturing test
procedures and fixtures.



We anticipate being able to move various aspects of our manufacturing
operations to third parties or other lower cost jurisdictions as production volumes increase. By moving to third parties, we would
benefit from contract manufacturing economies of scale, access to high quality production resources and reduced equipment capital
costs and equipment obsolescence risk. We have also commenced sourcing components from third parties in Asia and expect to increase
the volume over time to reduce our material costs.



We are dependent on third party suppliers for certain key materials
and components for our products such as membrane electrode assemblies and ultra capacitors. We believe we have sufficient sources
and price stability of our key materials and components.



We have certifications in ISO 9001-2008 in both our Oevel and Mississauga
facilities, and ISO 14001 and OHSAS 18001 in our Oevel facility.

performance based compensation structure. We have entered into non-disclosure and confidentiality agreements with key management
personnel and with substantially all employees. None of our employees are represented by a collective bargaining agreement and
we believe our relations with our employees are good.



Legal Proceedings



We are not currently party to any material legal proceedings.



Government Regulation



We are not subject to regulatory commissions governing traditional
electric utilities and other regulated entities in any of the jurisdictions that we operate in. Our products are however subject
to oversight and regulation by governmental bodies in regards to building codes, fire codes, public safety, electrical and gas
pipeline connections and hydrogen siting, among others.



4.Description of Share Capital



Our authorized capital consists of an unlimited number of common
shares and an unlimited number of preferred shares issuable in series, of which 12,540,757 common shares and no preferred shares
were issued and outstanding as of March 9, 2016.



Each common share carries one vote on all matters to be voted on
by our shareholders. Holders of common shares are entitled to receive dividends as and when declared by our Board of Directors
and to share ratably in our remaining assets available for distribution, after payment of liabilities, upon Hydrogenics’
liquidation, dissolution or winding up. Common shares do not carry pre-emptive rights or rights of conversion into any other securities.
All outstanding common shares are fully paid and non-assessable. There are no limitations on the rights of non-resident owners
of common shares to hold or vote their shares.



Our Board of Directors has the authority, without further action
by the shareholders, to issue an unlimited number of preferred shares in one or more series and, in the event that preferred shares
are issued, the Board also has the authority to fix the designations, powers, preferences, privileges and relative, participating,
optional or special rights of any preferred shares including any qualifications, limitations or restrictions. Special rights that
may be granted to a series of preferred shares include dividend rights, conversion rights, voting rights, redemption and liquidation
preferences, any or all of which may be superior to the rights of the common shares. Preferred share issuances could decrease the
market price of common shares and may adversely affect the voting and other rights of the holders of common shares. The issuance
of preferred shares could also have the effect of delaying or preventing a change in control of Hydrogenics.



5.Dividends



We have never declared or paid any cash dividends on our common
shares. We currently intend to retain any future earnings to fund the development and growth of our business and we do not anticipate
paying any cash dividends in the foreseeable future.

The Audit Committee charter requires each member of the Audit Committee
to be unrelated and independent, and the composition of the Audit Committee satisfy the independence, experience and financial
expertise requirements of the Nasdaq, the TSX and Section 10A of the Securities Exchange Act of 1934 (United States), as amended
by the Sarbanes-Oxley Act of 2002 (United States), and the rules promulgated thereunder. Accordingly, all committee members are
required to be financially literate or be willing and able to acquire the necessary knowledge quickly. Financial literacy means
the person has the ability to read and understand financial statements that present a breadth and level of complexity of accounting
issues that are generally comparable to the breadth and complexity of the issues that can reasonably be expected to be raised by
our consolidated financial statements. We believe all of the current members of the Audit Committee are financially literate.



In addition, the Audit Committee charter contains independence requirements
that each committee member must satisfy each current member meets those requirements. Specifically, the charter provides that no
member of the committee may be an officer or retired officer of Hydrogenics and each member must be independent of Hydrogenics
within the meaning of all applicable laws, rules and regulations and any other relevant consideration, including laws, rules and
regulations particularly applicable to Audit Committee members. We believe all of the current members of the Audit Committee are
independent.



The Audit Committee has a policy restricting the provision of non-audit
services by our auditors. Any such services must be permitted engagements as provided by the Audit Committee charter and must be
pre-approved by the Audit Committee. The Audit Committee also pre-approves audit services and the related fees.





8.Interest of Management and Others in Material Transactions



Transactions with Viking Engineering
& Tool Co.



In the normal course of operations, we subcontract certain machining
and sheet metal fabrication of parts to Viking Engineering & Tool Co., a company owned by the father and uncle of Joseph
Cargnelli, a director and senior officer of the Company and one of our principal shareholders. For the fiscal year ended December
31, 2015, billings by this related company totalled $0.1 million (2014 - $0.2 million, 2013 - $0.2 million). At December 31, 2015,
and February 29, 2016 we had an accounts payable balance due to this related company of less than $0.1 million in both periods.
We believe that transactions with this company are consistent with those we have with unrelated third parties.





Transactions with Joint Venture



The Company holds an equity investment in the joint venture Kolon
Hydrogenics. During 2015, the Company had sales to the joint venture of $0.7 million (2014 - $3.1 million), and at the end of December
31, 2015 the Company had a receivable of $0.4 million (2014 - $0.9 million) owing from the joint venture.

9.Risk Factors



An investment in our common shares involves risk. Investors
should carefully consider the risks described below and the other information contained in, and incorporated by reference in, this
annual information form, including management’s discussion and analysis and our financial statements for the year ended December
31, 2015, which is available on SEDAR atwww.sedar.com. The risks described below are not the only ones we face.
Additional risks and uncertainties, including those that we do not know about now or that we currently deem immaterial, may also
adversely affect our business.



Risk Factors Related to Our Financial Condition



Our inability to generate sufficient cash flows, raise additional
capital and actively manage our liquidity may impair our ability to execute our business plan, and result in our reducing or eliminating
product development and commercialization efforts, reducing our sales and marketing efforts, and having to forego attractive business
opportunities.

At December 31, 2015, we had approximately $24.9 million of cash
and cash equivalents and restricted cash (2014 - $10.6 million). Restricted cash of $1.5 million is held as partial security for
standby letters of credit and letters of finance. There are uncertainties related to the timing and use of our cash resources and
working capital requirements. These uncertainties include, among other things, the timing and volume of commercial sales and associated
gross margins of our existing products and the development of markets for, and customer acceptance of, new products. To the extent
possible, we attempt to limit the significance of these risks by: (i) continually monitoring our sales prospects; (ii) continually
aiming to reduce product cost; and (iii) advancing our technology platforms and product designs. However, given that many of the
above noted factors are outside of our control, we may not be able to accurately predict our necessary cash expenditures or obtain
financing in a timely manner to cover any shortfalls.



If we are unable to generate sufficient cash flows or obtain adequate
additional financing which, given the current global economy and credit markets, is challenging, we may be unable to respond to
the actions of our competitors or we may be prevented from executing our business plan, or conducting all or a portion of our planned
operations. In particular, the development and commercialization of our products could be delayed or discontinued if we are unable
to fund our research and product development activities or the development of our manufacturing capabilities. In addition, we may
be forced to reduce our sales and marketing efforts or forego attractive business opportunities.



The uncertain and unpredictable condition of the global economy
could have a negative impact on our business, results of operations and consolidated financial condition, or our ability to accurately
forecast our results, and it may cause a number of the risks that we currently face to increase in likelihood, magnitude and duration.

While we continuously monitor the state of the broader economic
climate and, particularly, the markets in which we operate, the uncertain and unpredictable condition of the current global economy
and credit markets affects our outlook in three distinct ways. First, our products depend to some degree on general world economic
conditions and activity. If the current condition of the economy declines or we experience a continued slow return to economic
growth, demand for our products is not likely to increase significantly. Second, the current uncertain economic climate could adversely
affect our ability to conduct normal day-to-day selling activities, which depend on the granting of short-term credit to a wide
variety of purchasers and, particularly, the corresponding needs of those purchasers. Third, those purchasers have a corresponding
need to finance purchases by accessing their own lines of credit, which could become increasingly difficult. If the current condition
of the economy does not continue to improve, our business will likely be adversely affected.



In the case of an economic decline or a sustained period of slow
economic growth, we expect to experience significant difficulties on a number of fronts. As a result, we may face new risks as
yet unidentified. In addition, a number of risks that we ordinarily face and that are further described herein may increase in
likelihood, magnitude and duration. These risks include but are not limited to deferrals or reductions of customer orders, potential
deterioration of our customers’ ability to finance purchases, reduced revenue, further deterioration in our cash balances
and liquidity due to negative foreign currency exchange rates, and an inability to access capital markets.



Our operating results may be subject to currency fluctuation.

Our monetary assets and liabilities denominated in currencies other
than the US dollar will give rise to a foreign currency gain or loss reflected in net income (loss). To the extent the Canadian
dollar or the Euro strengthens against the US dollar, we may incur foreign exchange losses on our net consolidated monetary asset
balance, which is denominated in those currencies. Such losses would be included in our financial results, and consequently, may
have an adverse effect on our share price.



As we currently have operations based in Canada and Europe, a significant
portion of our expenses are in Canadian dollars and Euros. However, a significant part of our revenues are currently generated
in US dollars and Euros, and we expect this will continue for the foreseeable future. In addition, we may be required to finance
our European operations by exchanging Canadian dollars or US dollars into Euros. The exchange rates between the Canadian dollar,
the US dollar and the Euro are subject to daily fluctuations in the currency markets and these fluctuations in market exchange
rates are expected to continue in the future. Such fluctuations affect both our consolidated revenues as well as our consolidated
costs. If the value of the US dollar weakens against the Canadian dollar or the Euro, the profit margin on our products may be
reduced. Also, changes in foreign exchange rates may affect the relative costs of operations and prices at which we and our foreign
competitors sell products in the same market. While we continuously monitor foreign exchange fluctuations and review forecasted
changes regularly, we currently have limited currency hedging through financial instruments. We carry a portion of our short-term
investments in Canadian dollars and Euros.



21






Our mix of revenues in the recent past does not reflect our current
business strategy, it may be difficult to assess our business and future prospects.

For the year ended December 31, 2015,
we derived $23.6 million or 66% of revenues from our sales of hydrogen generation products and services and $12.3 million, or 34%,
of our revenues from sales of power products and services. For the year ended December 31, 2014, we derived $30.2 million or 66%
of revenues from our sales of hydrogen generation products and services and $15.3 million, or 34%, of our revenues from sales of
power products and services.Our current business strategy is to develop, manufacture and sell hydrogen energy storage systems,
hydrogen generation products and fuel cell power products in larger quantities. Because we have made limited sales of hydrogen
energy storage systems and fuel cell power products to date, our historical operating data may be of limited value in evaluating
our future prospects.



We may not be able to implement our business strategy and the price of our common
shares may decline.

We have not generated positive net income since our inception. Our
current business strategy is to develop a portfolio of hydrogen and fuel cell products with market leadership positions for each
product. In so doing, we will continue to incur significant expenditures for general administrative activities, including sales
and marketing and product research and development. As a result of these costs, we will need to generate and sustain significantly
higher revenues and positive gross margins to achieve and sustain profitability. We incurred a net loss for the year ended December
31, 2015 of $11.7 million, and a net loss for the year ended ended December 31, 2014 of $4.5 million, and a net loss for the year
ended December 31, 2013. Our accumulated deficit as at December 31, 2015 was $361.6 million, at December 31, 2014 was $349.6 million,
and at December 31, 2013 was $345.4 million.



As noted above, our strategy to limit the significance of these
risks and uncertainties is to execute a business plan aimed at increasing market penetration to achieve
forecasted revenues, improving operating cash flows, continuing to invest in product research and development, entering into complementary
markets, improving overall gross margins, and securing additional financing to fund our operations as needed. However,we
expect to incur significant operating expenses over the next several years. Accordingly, we may not be able to implement our business
strategy and the price of our common shares may decline.



Our quarterly operating results are likely to fluctuate significantly
and may fail to meet the expectations of securities analysts and investors and may cause the price of our common shares to decline.

Our quarterly revenues and operating results have varied significantly
in the past and are likely to vary in the future. These quarterly fluctuations in our operating performance result from the length
of time between our first contact with a customer and the recognition of revenue from sales to that customer. Some of our products
are highly engineered and many are still in development stages; therefore, the length of time between approaching a customer and
delivering our products to that customer can span many quarterly periods. In many cases, a customer’s decision to buy our
products and services may require the customer to change its established business practices and to conduct its business in new
ways. As a result, we must educate customers on the use and benefits of our products and services. This can require us to commit
significant time and resources without necessarily generating any revenues. Many potential customers may wish to enter into trial
arrangements with us in order to use our products and services on a trial basis. The success of these trials may determine whether
or not the potential customer purchases our products or services on a commercial basis. Potential customers may also need to obtain
approval at a number of management levels and one or more regulatory approvals. This may delay a decision to purchase our products.



22






The length and variability of the sales cycles for our products
make it difficult to forecast accurately the timing and amount of specific sales and corresponding revenue recognition. The delay
or failure to complete one or more large sales transactions could significantly reduce our revenues for a particular quarter. We
may expend substantial funds and management effort during our sales cycle with no assurance that we will successfully sell our
products. As a result, our quarterly operating results are likely to fluctuate significantly and we may fail to meet the expectations
of securities analysts and investors, and the price of our common shares may decline.



We currently depend on a relatively limited number of customers
for a majority of our revenues and a decrease in revenue from these customers could materially adversely affect our business, consolidated
financial condition and results of operations.

While our business plan and sales and marketing strategy contemplates
a diverse base of future customers, to date a relatively limited number of customers have accounted for a majority of our revenues
and we expect they will continue to do so for the foreseeable future. Our four largest customers accounted for 29% of revenues
for the year ended December 31, 2015 (39% of revenues for the year ended December 31, 2014, 48% of revenues for the year ended
December 31, 2013). The identities of some of our largest customers have changed from year to year. Our arrangements with these
customers are generally non-exclusive, have no volume commitments and are often on a purchase order basis. We cannot be certain
customers who have accounted for significant revenue in past periods will continue to purchase our products and allow us to generate
revenues. Accordingly, our revenue and results of operations may vary from period to period. We are also subject to credit risk
associated with the concentration of our accounts receivable from these significant customers. If one or more of these significant
customers were to cease doing business with us, significantly reduce or delay purchases from us, or fail to pay on a timely basis,
our business, consolidated financial condition and results of operations could be materially adversely affected.



Our insurance may not be sufficient.

We carry insurance that we consider adequate considering the nature
of the risks and costs of coverage. We may not, however, be able to obtain insurance against certain risks or for certain products
or other resources located from time to time in certain areas of the world. We are not fully insured against all possible risks,
nor are all such risks insurable. Thus, although we maintain insurance coverage, such coverage may not be adequate.



Certain external factors may affect the value of goodwill, which
may require us to recognize an impairment charge.

Goodwill arising from our acquisition of Stuart Energy in 2005 comprises
approximately 6.9% of our total assets at December 31, 2015 (9.6% of our total assets at December 31, 2014, 13.1% of our total
assets at December 31, 2013). Economic, market, legal, regulatory, competitive, customer, contractual and other factors may affect
the value of goodwill. If any of these factors impair the value of these assets, accounting rules require us to reduce their carrying
value and recognize an impairment charge. This would reduce our reported assets and earnings in the year the impairment charge
is recognized.



Risk Factors Related to Our Business and Industry



Significant markets for fuel cell and other hydrogen energy products
may never develop or may develop more slowly than we anticipate. This would significantly harm our revenues and may cause us to
be unable to recover the losses we have incurred and expect to incur in the development of our products.

Significant markets may never develop for fuel cell and other hydrogen
energy products or they may develop more slowly than we anticipate. Any such delay or failure would significantly harm our revenues
and we may be unable to recover the losses we have incurred and expect to continue to incur in the development of our products.
If this were to occur, we may never achieve profitability and our business could fail. Fuel cell and other hydrogen energy products
represent an emerging market, and whether or not end-users will want to use them may be affected by many factors, some of which
are beyond our control, including: the emergence of more competitive technologies and products; other environmentally clean technologies
and products that could render our products obsolete; the future cost of hydrogen and other fuels used by our fuel cell products;
the future cost of the membrane electrode assembly used in our fuel cell products; the future cost of platinum group metals, a
key catalyst used in our fuel cell and hydrogen generation products; the regulatory requirements of agencies, including the development
of uniform codes and standards for fuel cell products, hydrogen refueling infrastructure and other hydrogen energy products; government
support by way of legislation, tax incentives, policies or otherwise, of fuel cell technology, hydrogen storage technology and
hydrogen refueling technology; the manufacturing and supply costs for fuel cell components and systems; the perceptions of consumers
regarding the safety of our products; the willingness of consumers to try new technologies; the continued development and improvement
of existing power technologies; and the future cost of fuels used in existing technologies.



23






Hydrogen may not be readily available on a cost-effective basis,
in which case our fuel cell products may be unable to compete with existing power sources and our revenues and results of operations
would be materially adversely affected.

If our fuel cell product customers are not able to obtain hydrogen
on a cost-effective basis, we may be unable to compete with existing power sources and our revenues and results of operations would
be materially adversely affected. Our fuel cell products require oxygen and hydrogen to operate. While ambient air can typically
supply the necessary oxygen, our fuel cells rely on hydrogen derived from water or from fuels, such as natural gas, propane, methanol
and other petroleum products. We manufacture and develop hydrogen generation systems called electrolyzers that use electricity
to separate water into its constituent parts of hydrogen and oxygen. In addition, third parties are developing systems to extract,
or reform, hydrogen from fossil fuels. Significant growth in the use of hydrogen powered devices, particularly in the motive power
market, may require the development of an infrastructure to deliver the hydrogen. There is no guarantee that such an infrastructure
will be developed on a timely basis or at all. Even if hydrogen is available for our products, if its price is such that electricity
or power produced by our systems would cost more than electricity provided by other means, we may be unable to compete successfully.



Changes in government policies and regulations could hurt the market for our products.

The fuel cell and hydrogen industry is in its development phase
and is not currently subject to industry specific government regulations in Canada, the European Union, the United States, as well
as other jurisdictions, relating to matters such as design, storage, transportation and installation of fuel cell systems and hydrogen
infrastructure products. However, given that the production of electrical energy has typically been an area of significant government
regulation, we expect we will encounter industry specific government regulations in the future in the jurisdictions and markets
in which we operate. For example, regulatory approvals or permits may be required for the design, installation and operation of
stationary fuel cell systems under federal, state and provincial regulations governing electric utilities and motive power fuel
cell systems under federal, state and provincial emissions regulations affecting automobile and truck manufacturers. To the extent
there are delays in gaining such regulatory approval, our development and growth may be constrained. Furthermore, the inability
of our potential customers to obtain a permit, or the inconvenience often associated with the permit process, could harm demand
for fuel cell and other hydrogen products and, therefore, harm our business.



Our business will suffer if environmental policies change and no
longer encourage the development and growth of clean power technologies. The interest by automobile manufacturers in fuel cell
technology has been driven in part by environmental laws and regulations. There is no guarantee these laws and regulations will
not change and any such changes could result in automobile manufacturers abandoning their interest in fuel cell powered vehicles.
In addition, if current laws and regulations are not kept in force, or if further environmental laws and regulations are not adopted,
demand for vehicular fuel cells may be limited.



The market for stationary and portable energy related products is
influenced by federal, state and provincial government regulations and policies concerning the electric utility industry. Changes
in regulatory standards or public policy could deter further investment in the research and development of alternative energy sources,
including fuel cells and fuel cell products, and could result in a significant reduction in the potential market demand for our
products. We cannot predict how changing government regulation and policies regarding the electric utility industry will affect
the market for stationary and portable fuel cell systems.



Although the development of alternative energy sources and, in particular,
fuel cells, has been identified as a significant priority by many governments, we cannot be assured that governments will not change
their priorities or that any such change would not materially affect our revenues and our business. If governments change their
laws and regulations such that the development of alternative energy sources is no longer required or encouraged, the demand for
alternative energy sources, such as our fuel cell products may be significantly reduced or delayed and our sales would decline.



24






Lack of new government policies and regulations for the energy
storage technologies could hurt the development of the Power-to-Gas market for our hydrogen energy storage products.

One of the critical factors for Power-to-Gas project developers
in securing project financing, or to justify the capital investment internally, is the ability to monetize a sufficient portion
of the “diffused benefits” of the project.  This may be accomplished through a contract mechanism or a combination
of new market reforms such as provision of new ancillary services such as load following or ramping service, tariffs for renewable
gas, and favourable electricity purchase provisions (eg. special exemption for transmission and network uplifts and other charges
on wholesale power purchases).  While Power-to-Gas demonstration projects are being built today, if new government regulations
for large scale energy storage projects are not implemented, or are not sufficient to justify the investment by project developers,
it would critically impede our ability to sell electrolyzers for commercial-scale Power-to-Gas into those markets.



The development of uniform codes and standards for hydrogen powered
vehicles and related hydrogen refueling infrastructure may not develop in a timely fashion, if at all.

Uniform codes and standards do not currently exist for fuel cell
systems, fuel cell components, hydrogen internal combustion engines or for the use of hydrogen as a vehicle fuel. Establishment
of appropriate codes and standards is a critical element to allow fuel cell system developers, fuel cell component developers,
hydrogen internal combustion engine developers, hydrogen infrastructure companies and hydrogen storage and handling companies to
develop products that will be accepted in the marketplace.



The development of hydrogen standards is being undertaken by numerous
organizations. Given the number of organizations pursuing hydrogen codes and standards, it is not clear whether universally accepted
codes and standards will occur in a timely fashion, if at all.



We could be liable for environmental damages resulting from our
research, development or manufacturing operations.

Our business exposes us to the risk of harmful substances escaping
into the environment, resulting in personal injury or loss of life, damage to or destruction of property, and natural resource
damage. Depending on the nature of the claim, our current insurance policies may not adequately reimburse us for costs incurred
in settling environmental damage claims and, in some instances, we may not be reimbursed at all. Our business is subject to numerous
laws and regulations that govern environmental protection and human health and safety. These laws and regulations have changed
frequently in the past and it is reasonable to expect additional more stringent changes in the future. Our operations may not comply
with future laws and regulations and we may be required to make significant unanticipated capital and operating expenditures. If
we fail to comply with applicable environmental laws and regulations, government authorities may seek to impose fines and penalties
on us, or to revoke or deny the issuance or renewal of operating permits, and private parties may seek damages from us. Under those
circumstances, we might be required to curtail or cease operations, conduct site remediation or other corrective action, or pay
substantial damage claims.



We currently face and will continue to face significant competition
from other developers and manufacturers of fuel cell power products and hydrogen generation systems. If we are unable to compete
successfully, we could experience a loss of market share, reduced gross margins for our existing products and a failure to achieve
acceptance of our proposed products.

In our markets for hydrogen generation systems, we compete with
a number of companies that develop and manufacture hydrogen generation products based on on-site water electrolysis and/or reforming
technologies. We also compete with suppliers of hydrogen gas that deliver hydrogen to the customer’s site in tube trailers
or cylinders or by pipeline. In many cases, these suppliers have established delivery infrastructure and customer relationships.



In the commercial production of fuel cell power products, we compete
with a number of companies that currently have fuel cell and fuel cell system development programs. We expect several of these
competitors will be able to deliver competing products to certain markets before we do. While our strategy is the development of
fuel cell and hydrogen generation technologies for sale to end-users, systems integrators, governments and market channel partners,
many of our competitors are developing products specifically for use in particular markets. These competitors may be more successful
in penetrating their specific markets than we are. In addition, an increase in the popularity of fuel cell power in particular
market channels may cause certain of our customers to develop and produce some or all of the fuel cell technologies we are developing.



Competition in the markets for fuel cell power modules and hydrogen
generation equipment is significant and will likely persist and intensify over time. We compete directly and indirectly with a
number of companies that provide products and services that are competitive with all, some or part of our products and related
services. Many of our existing and potential competitors have greater brand name recognition and their products may enjoy greater
initial market acceptance among our potential customers. In addition, many of these competitors have significantly greater financial,
technical, sales, marketing, distribution, service and other resources than we have and may also be better able to adapt quickly
to customers’ changing demands and to changes in technology.



25






While it is our strategy to continuously improve our products, if
we are unable to do so, and if we cannot generate effective responses to our competitors’ brand power, product innovations,
pricing strategies, marketing campaigns, partnerships, distribution channels, service networks and other initiatives, our ability
to gain market share or market acceptance for our products could be limited, our revenues and our profit margins may suffer, and
we may never become profitable.



We face competition for fuel cell power products from developers and manufacturers
of traditional technologies and other alternative technologies.

Each of our target markets is currently served by manufacturers
with existing customers and suppliers. These manufacturers use proven and widely accepted traditional technologies such as internal
combustion engines and turbines, as well as coal, oil, gas and nuclear powered generators. Additionally, there are competitors
working on developing technologies that use other types of fuel cells, energy storage technologies, hydrogen generation technologies
and other alternative power technologies, advanced batteries and hybrid battery/internal combustion engines, which may compete
for our target customers. Given that PEM fuel cells and electrolyzers have the potential to replace these existing power sources,
competition in our target markets will also come from these traditional power technologies, from improvements to traditional power
technologies and from new alternative power technologies, including other types of fuel cells.



If we are unable to continuously improve our products and if we
cannot generate effective responses to incumbent and/or alternative energy competitors’ brand power, product innovations,
pricing strategies, marketing campaigns, partnerships, distribution channels, service networks and other initiatives, our ability
to gain market share or market acceptance for our products could be limited, our revenues and our profit margins may suffer, and
we may never become profitable.



Our strategy for the sale of fuel cell power products depends
on developing partnerships with OEMs, governments, systems integrators, suppliers and other market channel partners who will incorporate
our products into theirs.

Other than in a few specific markets, our strategy is to develop
and manufacture products and systems for sale to OEMs, governments, systems integrators, suppliers and other market channel partners
that have mature sales and distribution networks for their products. Our success may be heavily dependent on our ability to establish
and maintain relationships with these partners who will integrate our fuel cell products into their products and on our ability
to find partners who are willing to assume some of the research and development costs and risks associated with our technologies
and products. Our performance may, as a result, depend on the success of other companies, and there are no assurances of their
success. We can offer no guarantee that OEMs, governments, systems integrators, suppliers and other market channel partners will
manufacture appropriate products or, if they do manufacture such products, that they will choose to use our products as components.
The end products into which our fuel cell technology will be incorporated will be complex appliances comprising many components
and any problems encountered by such third parties in designing, manufacturing or marketing their products, whether or not related
to the incorporation of our fuel cell products, could delay sales of our products and adversely affect our financial results. Our
ability to sell our products to the OEM markets depends to a significant extent on our partners’ worldwide sales and distribution
networks and service capabilities. In addition, some of our agreements with customers and partners require us to provide shared
intellectual property rights in certain situations, and there can be no assurance that any future relationships we enter into will
not require us to share some of our intellectual property. Any change in the fuel cell, hydrogen or alternative fuel strategies
of one of our partners could have a material adverse effect on our business and our future prospects.



In addition, in some cases, our relationships are governed by a
non-binding memorandum of understanding or a letter of intent. We cannot provide the assurance that we will be able to successfully
negotiate and execute definitive agreements with any of these partners, and failure to do so may effectively terminate the relevant
relationship. We also have relationships with third party distributors who also indirectly compete with us. For example, we have
targeted industrial gas suppliers as distributors of our hydrogen generators. Because industrial gas suppliers currently sell hydrogen
in delivered form, adoption by their customers of our hydrogen generation products could cause them to experience declining demand
for delivered hydrogen. For this reason, industrial gas suppliers may be reluctant to purchase our hydrogen generators. In addition,
our third party distributors may require us to provide volume price discounts and other allowances, or customize our products,
either of which could reduce the potential profitability of these relationships.



26






We are dependent on third party suppliers for key materials and
components for our products. If these suppliers become unable or unwilling to provide us with sufficient materials and components
on a timely and cost-effective basis, we may be unable to manufacture our products cost-effectively or at all, and our revenues
and gross margins would suffer.

We rely on third party suppliers to provide key materials and components
for our fuel cell power products and hydrogen generation products. While we undertake due diligence before engaging with a supplier,
a supplier’s failure to provide materials or components in a timely manner, or to provide materials and components that meet
our quality, quantity or cost requirements, or our inability to obtain substitute sources for these materials and components in
a timely manner or on terms acceptable to us, may harm our ability to manufacture our products cost-effectively or at all, and
our revenues and gross margins might suffer. To the extent we are unable to develop and patent our own technology and manufacturing
processes and, to the extent that the processes our suppliers use to manufacture materials and components are proprietary, we may
be unable to obtain comparable materials or components from alternative suppliers and that could adversely affect our ability to
produce commercially viable products.



We may not be able to manage successfully the anticipated expansion of our operations.

The uneven pace of our anticipated expansion in facilities, staff
and operations may place serious demands on our managerial, technical, financial and other resources. We may be required to make
significant investments in our engineering and logistics systems and our financial and management information systems, as well
as retaining, motivating and effectively managing our employees. While we continually monitor our sales outlook and adjust our
business plans as necessary, our management skills and systems currently in place may not enable us to implement our strategy or
to attract and retain skilled management, engineering and production personnel. Our failure to manage our growth effectively or
to implement our strategy in a timely manner may significantly harm our ability to achieve profitability.



If we do not properly manage foreign sales and operations, our business could suffer.

We expect that a substantial portion of our future revenues will
continue to be derived from foreign sales. Our international activities may be subject to inherent risks, including regulatory
limitations restricting or prohibiting the provision of our products and/or services, unexpected changes in regulatory requirements,
tariffs, customs, duties and other trade barriers, difficulties in staffing and managing foreign operations, longer payment cycles,
problems in collecting accounts receivable, fluctuations in currency exchange rates, foreign exchange controls that restrict or
prohibit repatriation of funds, technology export and/or import restrictions or prohibitions, delays from customs brokers or government
agencies, seasonal reductions in business activity and potentially adverse tax consequences resulting from operating in multiple
jurisdictions. While we aim to employ experienced knowledgeable management in our foreign operations, if we do not properly manage
foreign operations, our business could suffer.



We will need to recruit, train and retain key management and other qualified personnel
to successfully expand our business.

Our future success will depend in large part on our ability to recruit
and retain experienced research and development, engineering, manufacturing, operating, sales and marketing, customer service and
management personnel. We compete in emerging markets and there are a limited number of people with the appropriate combination
of skills needed to provide the services our customers require. In the past, we have experienced difficulty in recruiting qualified
personnel and we expect to experience continued difficulties in personnel recruiting. If we do not attract such personnel, we may
not be able to expand our business. In addition, new employees generally require substantial training, which requires significant
resources and management attention. Our success also depends on retaining our key management, research, product development, engineering,
marketing and manufacturing personnel. Even if we invest significant resources to recruit, train and retain qualified personnel,
we may not be successful in our efforts.



We may acquire technologies or companies in the future, and these acquisitions could
disrupt our business and dilute our shareholders’ interests.

We may acquire additional technologies or other companies in the
future and we cannot provide assurances that we will be able to successfully integrate their operations or that the cost savings
we anticipate will be fully realized. Entering into an acquisition or investment entails many risks, any of which could materially
harm our business, including: diversion of management’s attention from other business concerns; failure to effectively assimilate
the acquired technology, employees or other assets into our business; the loss of key employees from either our current business
or the acquired business; and the assumption of significant liabilities of the acquired company.



27






If we complete additional acquisitions, we may dilute the ownership
of current shareholders. In addition, achieving the expected returns and cost savings from our past and future acquisitions will
depend in part on our ability to integrate the products and services, technologies, research and development programs, operations,
sales and marketing functions, finance, accounting and administrative functions, and other personnel of these businesses into our
business in an efficient and effective manner. We cannot ensure we will be able to do so or that the acquired businesses will perform
at anticipated levels. If we are unable to successfully integrate acquired businesses, our anticipated revenues may be lower and
our operational costs may be higher.



We have no experience manufacturing our fuel cell products on
a large scale basis and if we do not develop adequate manufacturing processes and capabilities to do so in a timely manner, we
will be unable to achieve our growth and profitability objectives.

We have manufactured most of our products in our Power Systems segment
for prototypes and initial sales, and we have limited experience manufacturing products on a larger scale. We have experience manufacturing
products on a larger scale in our Generation segment. In order to produce certain of our products at affordable prices, we will
have to manufacture a large volume of such products. While several members of our senior management team have significant experience
in developing high volume manufacturing strategies for new products and while we have developed plans for efficient, low-cost manufacturing
capabilities and processes that will enable us to meet the quality, price, engineering, design and production standards or production
volumes required to successfully mass market such products, we do not know whether these plans will be implemented such that they
will satisfy the requirements of our customers and the market for the Power Systems segment. Our failure to develop these manufacturing
processes and capabilities in a timely manner could prevent us from achieving our growth and profitability objectives.





Risk Factors Related to Our Products and Technology



We may never complete the development of commercially viable
fuel cell power products and/or commercially viable hydrogen generation systems for new hydrogen energy applications, and if we
fail to do so, we will not be able to meet our business and growth objectives.

We have made commercial sales of fuel cell power modules, integrated
fuel cell systems, hydrogen refueling stations and hydrogen energy storage systems for a relatively short period of time. Because
both our business and industry are still in the developmental stage, we do not know when or whether we will successfully complete
research and development of commercially viable fuel cell power products and commercially viable hydrogen generation equipment
for new hydrogen energy applications. If we do not complete the development of such commercially viable products, we will be unable
to meet our business and growth objectives. We expect to face unforeseen challenges, expenses and difficulties as a developing
company seeking to design, develop and manufacture new products in each of our targeted markets. Our future success also depends
on our ability to effectively market fuel cell products and hydrogen generation products once developed.



We must lower the cost of our fuel cell and hydrogen generation
products and demonstrate their reliability or consumers will be unlikely to purchase our products and we will therefore not generate
sufficient revenues to achieve and sustain profitability.

While we have significantly reduced the cost of our technology and
products in the past few years and we are continuously seeking and implementing additional product and manufacturing cost reductions,
fuel cells currently cost more than many established competing technologies, such as internal combustion engines and batteries.
The prices of fuel cell and hydrogen generation products are dependent largely on material and manufacturing costs. We cannot guarantee
we will be able to lower these costs to a level where we will be able to produce a competitive product or that any product we produce
using lower cost materials and manufacturing processes will not suffer from lower performance, reliability and longevity. If we
are unable to produce fuel cell and hydrogen generation products that are competitive with other technologies in terms of price,
performance, reliability and longevity, consumers will be unlikely to buy our fuel cell and hydrogen generation products. Accordingly,
we would not be able to generate sufficient revenues with positive gross margins to achieve and sustain profitability.



Any failures or delays in field tests of our products could negatively
affect our customer relationships and increase our manufacturing costs.

We regularly field test our products and we plan to conduct additional
field tests in the future. While we dynamically manage the execution and results of these tests, any failures or delays in our
field tests could harm our competitive position and impair our ability to sell our products. Our field tests may encounter problems
and delays for a number of reasons, including the failure of our technology, the failure of the technology of others, the failure
to combine these technologies properly, operator error and the failure to maintain and service the test prototypes properly. Many
of these potential problems and delays are beyond our control. In addition, field test programs, by their nature, may involve delays
relating to product roll-out and modifications to product design, as well as third party involvement. Any problem or perceived
problem with our field tests, whether it originates from our technology, our design, or third parties, could damage our reputation
and the reputation of our products and limit our sales. Such field test failures may negatively affect our relationships with customers,
require us to extend field testing longer than anticipated before undertaking commercial sales and require us to develop further
our technology to account for such failures prior to the field tests, thereby increasing our manufacturing costs.



28






The components of our products may contain defects or errors
that could negatively affect our customer relationships and increase our development, service and warranty costs.

Our products are complex and must meet the stringent technical requirements
of our customers. The software and other components used in our fuel cell and hydrogen generation products may contain undetected
defects or errors, especially when first introduced, which could result in the failure of our products to perform, damage to our
reputation, delayed or lost revenue, product returns, diverted development resources and increased development, service and warranty
costs.



Rapid technological advances or the adoption of new codes and
standards could impair our ability to deliver our products in a timely manner and, as a result, our revenues would suffer.

While we actively and continuously monitor the developing markets
and regulations in markets for our products, our success depends in large part on our ability to keep our products current and
compatible with evolving technologies, codes and standards. Unexpected changes in technology or in codes and standards could disrupt
the development of our products and prevent us from meeting deadlines for the delivery of products. If we are unable to keep pace
with technological advancements and adapt our products to new codes and standards in a timely manner, our products may become uncompetitive
or obsolete and our revenues would suffer.



We depend on intellectual property and our failure to protect
that intellectual property could adversely affect our future growth and success.

While we proactively and regularly review our intellectual property
protection strategy, failure to protect our intellectual property rights may reduce our ability to prevent others from using our
technology. We rely on a combination of patent, trade secret, trademark and copyright laws to protect our intellectual property.
Some of our intellectual property is currently not covered by any patent or patent application. Patent protection is subject to
complex factual and legal criteria that may give rise to uncertainty as to the validity, scope and enforceability of a particular
patent. Accordingly, we cannot be assured that: any of the United States, Canadian or other patents owned by us or third party
patents licensed to us will not be invalidated, circumvented, challenged, rendered unenforceable, or licensed to others; or any
of our pending or future patent applications will be issued with the breadth of protection that we seek, if at all.



In addition, effective patent, trademark, copyright and trade secret
protection may be unavailable, limited, not applied for, or unenforceable in foreign countries.



Furthermore, although we typically retain sole ownership of the
intellectual property we develop, in certain circumstances we provide for shared intellectual property rights.



We have also entered into agreements with other customers and partners
that involve shared intellectual property rights. Any developments made under these agreements will be available for future commercial
use by all parties to the agreement.



We also seek to protect our proprietary intellectual property through
contracts including, when possible, confidentiality agreements and inventors’ rights agreements with our customers and employees.
We cannot be sure that the parties who enter into such agreements with us will not breach them, that we will have adequate remedies
for any breach or that such persons or institutions will not assert rights to intellectual property arising out of these relationships.
If necessary or desirable, we may seek licences under the patents or other intellectual property rights of others. However, we
cannot be sure we will obtain such licences or that the terms of any offered licences will be acceptable to us. Our failure to
obtain a licence from a third party for intellectual property we use in the future could cause us to incur substantial liabilities
and to suspend the manufacture and shipment of products or our use of processes that exploit such intellectual property.



Our involvement in intellectual property litigation could negatively
affect our business.

Our future success and competitive position depend in part on our
ability to obtain or maintain the proprietary intellectual property used in our principal products. In order to establish and maintain
such a competitive position, we may need to prosecute claims against others who we believe are infringing our rights and defend
claims brought by others who believe we are infringing their rights. Our involvement in intellectual property litigation could
result in significant expense to us, adversely affect the sale of any products involved or the use or licensing of related intellectual
property and divert the efforts of our technical and management personnel from their principal responsibilities, regardless of
whether such litigation is resolved in our favour. If we are found to be infringing on the intellectual property rights of others,
we may, among other things, be required to: pay substantial damages; cease the development, manufacture, use, sale or importation
of products that infringe on such intellectual property rights; discontinue processes incorporating the infringing technology;
expend significant resources to develop or acquire non-infringing intellectual property; or obtain licences to the relevant intellectual
property.



29






We cannot offer any assurance we will prevail in any such intellectual
property litigation or, if we were not to prevail in such litigation that licences to the intellectual property we are found to
be infringing on would be available on commercially reasonable terms, if at all. The cost of intellectual property litigation as
well as the damages, licensing fees or royalties that we might be required to pay could have a material adverse effect on our business
and financial results.



Our products use flammable fuels that are inherently dangerous
substances and could subject us to product liabilities.

While it is a key focus of management to develop and manufacture
safe and reliable products, our financial results could be materially impacted by accidents involving either our products or those
of other fuel cell manufacturers, either because we face claims for damages or because of the potential negative impact on demand
for fuel cell products. Our products use hydrogen, which	 is typically generated from gaseous and liquid fuels, such as propane,
natural gas or methanol, in a process known as reforming. While our fuel cell products do not use these fuels in a combustion process,
natural gas, propane and other hydrocarbons are flammable fuels that could leak and then combust if ignited by another source.
In addition, certain of our OEM partners and customers may experience significant product liability claims. As a supplier of products
and systems to these OEMs, we face an inherent business risk of exposure to product liability claims in the event our products,
or the equipment into which our products are incorporated, malfunction and result in personal injury or death. We may be named
in product liability claims even if there is no evidence our systems or components caused the accidents. Product liability claims
could result in significant losses from expenses incurred in defending claims or the award of damages. Since our products have
not yet gained widespread market acceptance, any accidents involving our systems, those of other fuel cell products or those used
to produce hydrogen could materially impede acceptance of our products. In addition, although our management believes our liability
coverage is currently adequate to cover these risks, we may be held responsible for damages beyond the scope of our insurance coverage.





Risk Factors Related to Ownership of Our Common Shares



If at any time we are classified as a passive foreign investment
company under United State tax laws, our US shareholders may be subject to adverse tax consequences.

We would be classified as a passive foreign investment company (“PFIC”),
for US federal income tax purposes, in any taxable year in which, after applying relevant look-through rules with respect to the
income and assets of our subsidiaries, either at least 75% of our gross income is ‘‘passive income,’’ or
on average at least 50% of the gross value of our assets is attributable to assets that produce passive income or are held for
the production of passive income.



Based on our structure, and the composition of our income and assets,
we do not believe we were a PFIC for the taxable year ended December 31, 2015 or the prior taxable year. However, there can be
no assurance the Internal Revenue Service will not successfully challenge our position or that we will not become a PFIC in a future
taxable year, as PFIC status is retested each year and depends on our assets and income in that year. If we are classified as a
PFIC at any time that a US shareholder holds our common shares, such shareholder may be subject to an increased US federal income
tax liability and a special interest charge in respect of a gain recognized on the sale or other disposition of our common shares
and upon the receipt of certain ‘‘excess distributions’’ (as defined in the United States Internal Revenue
Code of 1986, as amended).



US shareholders should consult their own tax advisors concerning
the US federal income tax consequences of holding our common shares if we were a PFIC in any taxable year and its potential application
to their particular situation.



30






A limited number of shareholders collectively own a significant
portion of our common shares and may act, or prevent corporate actions, to the detriment of other shareholders.

A limited number of shareholders, including our founders, CommScope,
Enbridge, and General Motors, currently own a significant portion of our outstanding common shares. CommScope currently owns approximately
10.6% of our outstanding common shares. Enbridge currently owns approximately 4.7% of our outstanding common shares. General Motors
currently owns approximately 4.5% of our outstanding common shares. Accordingly, these shareholders may exercise significant influence
over all matters requiring shareholder approval, including the election of a majority of our directors and the determination of
significant corporate actions. This concentration could also have the effect of delaying or preventing a change in control that
could otherwise be beneficial to our shareholders.



If we fail to maintain the requirements for continued listing
on Nasdaq, our common shares could be delisted from trading on Nasdaq, which would materially adversely affect the liquidity of
our common shares, the price of our common shares, and our ability to raise additional capital.

Failure to meet the applicable continued listing requirements of
Nasdaq could result in our common shares being delisted from Nasdaq. In the past we have been unable to meet the Nasdaq requirements
for continued listing on the Nasdaq Global Market for certain periods of time, and though we have regained compliance of such requirements,
we may not be able to meet the requirements in the future. On September 18, 2012, we received notices from Nasdaq informing us
that we failed to maintain a market value of listed securities of at least $50.0 million for 30 consecutive business days, in addition
to the fact that we did not meet the minimum $50.0 million total assets and total revenues standard under Nasdaq Listing Rule 5450(b)(3)(A).
We were given 180 days to regain compliance by having our market capitalization exceed $50.0 million for a minimum of 10 consecutive
business days prior to the end of the 180-day period. We regained compliance on December 10, 2012.



If we fail to satisfy Nasdaq’s continued listing requirements,
our common shares could be delisted from Nasdaq, in which case we may transfer to the Nasdaq Capital Market, which generally has
lower financial requirements for initial listing or, if we fail to meet its listing requirements, the over-the-counter bulletin
board. However, there can be no assurance that our common shares will be eligible for trading on any such alternative exchanges
or markets in the United States. If we are delisted from Nasdaq, it could materially reduce the liquidity of our common shares,
lower the price of our common shares, and impair our ability to raise financing.



Future sales of common shares by our principal shareholders could
cause our share price to fall and reduce the value of a shareholder’s investment.

If our principal shareholders, including our founders, sell substantial
amounts of their common shares in the public market, the market price of our common shares could fall and the value of a shareholder’s
investment could be reduced. The perception among investors that these sales may occur could have a similar effect. Share price
declines may be exaggerated if the low trading volume that our common shares have experienced to date continues. These factors
could also make it more difficult for us to raise additional funds through future offerings of our common shares or other securities.



Our articles of incorporation authorize us to issue an unlimited
number of common and preferred shares. Significant issuances of common or preferred shares could dilute the share ownership of
our shareholders, deter or delay a takeover of us that our shareholders may consider beneficial or depress the trading price of
our common shares.

Our articles of incorporation permit us to issue an unlimited number
of common and preferred shares. If we were to issue a significant number of common shares, it would reduce the relative voting
power of previously outstanding shares. Such future issuances could be at prices less than our shareholders paid for their common
shares. If we were to issue a significant number of common or preferred shares, these issuances could also deter or delay an attempted
acquisition of us that a shareholder may consider beneficial, particularly, in the event that we issue preferred shares with special
voting or dividend rights. While NASDAQ and Toronto Stock Exchange rules may require us to obtain shareholder approval for significant
issuances, we would not be subject to these requirements if we ceased, voluntarily or otherwise, to be listed on NASDAQ and the
Toronto Stock Exchange. Significant issuances of our common or preferred shares, or the perception that such issuances could occur,
could cause the trading price of our common shares to drop.



US investors may not be able to enforce US civil liability judgments
against us or our directors and officers.

We are organized under the laws of Canada. A majority of our directors
and officers are residents of Canada and all or a substantial portion of their assets and substantially all of our assets are located
outside of the United States. As a result, it may be difficult for US holders of our common shares to effect service of process
on these persons within the United States or to realize in the United States on judgments rendered against them. In addition, a
shareholder should not assume that the courts of Canada: (i) would enforce the judgments of US courts obtained in actions against
us or such persons predicated on the civil liability provisions of US federal securities laws or other laws of the United States;
or (ii) would enforce, in original actions, claims against us or such persons predicated on the US federal securities laws.



31






Our share price is volatile and we may continue to experience
significant share price and volume fluctuations.

Since our common shares were initially offered to the public in
November 2000, the stock markets, particularly in the technology and alternative energy sectors, and our share price have experienced
significant price and volume fluctuations. Our common shares may continue to experience volatility for reasons unrelated to our
own operating performance, including: performance of other companies in the fuel cell or alternative energy business; news announcements,
securities analysts’ reports and recommendations and other developments with respect to our industry or our competitors;
or changes in general economic conditions.



As at December 31, 2015 there were 536,174 stock options to purchase
our common shares. If these securities are exercised, our shareholders will incur substantial dilution.

A significant element in our business plan to attract and retain
qualified personnel is the issuance to such persons options to purchase our common shares. At December 31, 2015, we have issued
and have outstanding 536,174 options to purchase our common shares at an average price of CA$6.97 per common share. Accordingly,
to the extent that we are required to issue significant numbers of options to our employees, and such options are exercised, our
shareholders could experience significant dilution.







10.TRANSFER AGENTS AND REGISTRARS



The registrar and transfer agent for our common shares in Canada
is CST Trust Company at its principal offices in Toronto, Ontario and the co-transfer agent and co-registrar for our common shares
in the United States is Computershare Investor Services LLC at its offices in New York, New York.

                                         Committee Authority and Responsibilities
                                                                        
                                                                        The Audit Committee shall have the sole authority to appoint or replace the public accountants (subject, if applicable, to shareholder ratification), and shall approve all audit engagement fees and terms and all non-audit engagements with the |  | public accountants.  The Audit Committee shall consult with management but shall not delegate these responsibilities.  In its capacity as a committee of the Board, the Audit Committee shall be directly responsible for the oversight of the work of the public accounting firm (including resolution of disagreements between management and the public accounting firm regarding financial reporting) for the purpose of preparing or issuing an audit report or related work, and the public accounting firm shall report directly to the Audit Committee.  The Audit Committee shall have the authority, to the extent it deems necessary or appropriate, to retain and set and pay the compensation for special legal, accounting or other consultants to advise the committee and carry out its duties, and to conduct or authorize investigations into any matters within its scope of responsibilities.
                                                   
                                                   The Audit Committee may request any officer or employee of the Company or the Company’s outside counsel or public accountants to attend a meeting of the Audit Committee or to meet with any members of, or consultants to, the Audit Committee.  The Audit Committee shall have the ability to communicate directly with the public accountants and the Company’s internal auditor (if applicable).
                                                   
                                                   The Audit Committee shall make regular reports to the Board.  The Audit Committee shall review and reassess the adequacy of this Charter annually and recommend any proposed changes to the Board for approval.  The Audit Committee shall annually review the Audit Committee’s own performance.
                                                   
                                                   In performing its functions, the Audit Committee shall undertake those tasks and responsibilities that, in its judgment, would most effectively contribute and implement the purposes of the Audit Committee.  The following functions are some of the common recurring activities of the Audit Committee in carrying out its oversight responsibility:
                                                   
                                                   •    Review and discuss with management and the public accountants the Company’s annual audited consolidated financial statements, including disclosures made in Management’s Discussion and Analysis of Financial Condition and Results of Operations and recommend to the Board whether the audited consolidated financial statements should be included in the Company’s annual report.
                                                   
                                                   •   Review and discuss with management and the public accountants the
                                                   Company’s quarterly financial statements, including disclosures made in Management’s Discussion and Analysis
