This presentation contains forward-looking statements, including, but not limited to, statements related to Horizon's offer to exchange
its ordinary shares  for all issued and outstanding shares of Depomed’s stock and the potential strategic and financial benefits thereof,
the future financial performance and prospects of each of Horizon and Depomed, Horizon’s business strategy and plans and other
statements that are not historical facts. 
These forward-looking statements are based on Horizon's current expectations and inherently involve significant risks and
uncertainties. Actual results and the timing of events could differ materially from those anticipated in such forward-looking statements
as a result of these risks and uncertainties, which include, without limitation, risks that the conditions to the exchange offer will not be
satisfied, Horizon will ultimately not pursue a transaction with Depomed or Depomed will reject engaging in any transaction with
Horizon;  if the conditions of the exchange offer are satisfied and/or a transaction is negotiated between Horizon and Depomed, risks
related to Horizon's ability to complete the acquisition on the proposed terms;  the possibility that competing offers will be made;  risks
associated with business combination transactions, such as the risk that the businesses will not be integrated successfully, that such
integration may be more difficult, time-consuming or costly than expected or that the expected benefits of the acquisition will not be
realized;  risks related to future opportunities and plans for the combined company, including uncertainty of the expected financial
performance and results of the combined company following completion of the proposed acquisition;  disruption from the proposed
acquisition, making it more difficult to conduct business as usual or maintain relationships with customers, employees or suppliers; 
and the possibility that if the combined company does not achieve the perceived benefits of the proposed acquisition as rapidly or to
the extent anticipated by financial analysts or investors, the market price of Horizon's shares could decline, as well as other risks
related to the Horizon and Depomed's businesses, including the ability to grow sales and revenues from existing products; 
competition, including potential generic competition;  the ability to protect intellectual property and defend patents;  regulatory
obligations and oversight;  and those risks detailed from time-to-time under the caption "Risk Factors" and elsewhere in Horizon's and
Depomed's respective filings and reports with the U.S. Securities and Exchange Commission.  Horizon Pharma undertakes no duty or
obligation to update any forward-looking statements contained in this presentation as a result of new information except as required by
applicable law or regulation.

Forward-Looking Statements

Non-Confidential Information – Horizon Pharma plc
Horizon Pharma provides certain financial measures such as adjusted EBITDA, or earnings before interest, taxes, depreciation and
amortization, pro forma net sales adjusted for sales of certain products pre-acquisition and adjusted net income that include
adjustments to GAAP figures. Adjustments to GAAP figures as well as EBITDA exclude acquisition transaction related expenses,
loss on debt extinguishment, as well as non-cash items such as share-based compensation, depreciation and amortization, royalty
accretion, non-cash interest expense, and other non-cash adjustments. Certain other special items or substantive events may also
be included in the non-GAAP adjustments periodically when their magnitude is significant within the periods incurred. In the case of
pro forma net sales, the figures exclude net sales of orphan and oncology products and include net sales attributed to other
companies that marketed certain products prior to their acquisition by Horizon Pharma or Depomed, as applicable. 
Horizon Pharma believes that these non-GAAP financial measures, when considered together with the GAAP figures, can
enhance an overall understanding of Horizon Pharma's and Depomed’s financial performance.  The non-GAAP financial measures
are included with the intent of providing investors with a more complete understanding of the Company’s operational results, trends
and expectations, including in relation to Depomed.  In addition, these non-GAAP financial measures are among the indicators
Horizon Pharma’s management uses for planning and forecasting purposes and measuring the Company's performance.  These
non-GAAP financial measures should be considered in addition to, and not as a substitute for, or superior to, financial measures
calculated in accordance with GAAP.  The non-GAAP financial measures used by the Company may be calculated differently from,
and therefore may not be comparable to, non-GAAP financial measures used by other companies.  The Company has not
provided a reconciliation of adjusted EBITDA or adjusted net income outlook for future periods to a net income (loss) outlook
because certain items that are a component of net income (loss) but not part of adjusted EBITDA and/or adjusted net income, such
as the gain (loss) on derivative revaluation associated with convertible senior notes, stock compensation, acquisition related
expenses and certain purchase accounting items such as intangibles and step-up inventory, cannot be reasonably projected, either
due to the significant impact of changes in Horizon Pharma's or Depomed’s stock price on share-based compensation, the
variability associated with acquisition related expenses due to timing and other factors.

Operational Synergies
(1)
Tax Synergies
Horizon expects combined company tax rate
to be in the mid-single digits, increasing to
the low-teens over the next five years
We believe that the costs of operating
Depomed’s existing business could be
significantly reduced through the elimination
of certain general and administrative costs,
including consolidation of locations,
reductions in headcount and elimination of
duplicate external costs, including public
company expenses
“DEPO should have a long term tax rate in
the high 30's.”
Piper Jaffray, July 7, 2015, Depomed
“DEPO pays a corporate tax rate of 37%
and HZNP of course has a tax-advantaged
corporate structure in place.”
Piper Jaffray, July 7, 2015, Depomed
“Given the broader platform, larger
anticipated rep base and re-price potential
we think HZNP could drive upside.
NUCYNTA is the biggest value driver with
each 500 bps of annual TRx growth through
2022E driving +$3 in NPV (and opportunity
in other products).
Other synergy
opportunities are to refinance the 10.75%
debt, cut G&A and lower the full DEPO tax
rate.”

“We had been evaluating the performance
of XARTEMIS XR.
And certainly, as the
company has changed its focus to
autoimmune rare diseases in the hospital
sector, our emphasis on the office space
pain activities has certainly been less
strategic.
And so in light of that change in
strategic direction, coupled with the
performance of XARTEMIS XR, as of June,
we have discontinued promotion of
XARTEMIS XR, and we're considering a
number of different strategic alternatives for
that product.”

“…called MNK-155, and it's a combination
product of hydrocodone and acetaminophen with
similar technology to that of XARTEMIS XR.  And
again, it would be focused on the office space
pain marketplace, which, as I mentioned, is not
really a strategic focus for us going forward.”

“Perception that this deal may
not generate an adequate
amount of synergies to be
attractive does not make sense
to us.
If we looked through
Horizon's past deal transaction
history, none was built on cost
cutting
-
rather
all
were
based
on generating revenue upside
from increased promotion and
better pharmacy pull through.
We see the Depomed deal as
being no different.”
Leerink, Depomed
“Per our earlier note, we believe
the asset is worth more in the
hands of Horizon given the
greater S&M resources Horizon
could provide, cost savings
opportunity, ability to refinance
the 10.75% debt and expected
reduction of the tax burden.”
“Viewing the proposed
Depomed transaction within that
broader context of Horizon's
evolution, we believe this
transaction makes exceedingly
good strategic sense, is nicely
value creating and provides
enhanced and durable
diversification.”
Cowen, Horizon
“The debate whether Depomed
overpaid for Nucynta is yet to be
determined, but we believe this
is a growth product and the
numbers work better within
Horizon with the significant tax
advantages.”
“We continue to view a HZNP-
DEPO combination as attractive,
and believe HZNP has made a
strong case to DEPO
shareholders.”

Continues to Work Against the Best Interests
of Shareholders
Horizon Pharma believes that Depomed will do whatever it can to delay
Depomed’s shareholders from expressing their views on Horizon Pharma’s
proposals
On July 12
, Depomed’s board adopted the Poison Pill
That same day, Depomed’s board amended the Depomed bylaws to allow the
Depomed board to delay any special meeting of Depomed shareholders to vote
on any Horizon Pharma proposals for almost five months
On August 21    
, Depomed informed Horizon Pharma that it was not allowing
Horizon Pharma to hold a single special meeting to hear all of its proposals
without incurring further delays
On August 31  
, Depomed informed Horizon Pharma that it had set the record
date for determining shareholders eligible to call the first special meeting as
October 29, 2015, 87 days after the initial request and the SECOND TO LAST
possible day that it could under the Depomed bylaws
On September 15      
, Depomed informed Horizon Pharma that it had set the
record date for determining shareholders eligible to call the second special
meeting as November 13, 2015, 86 days after the initial request and the THIRD TO
