NOTES TO UNAUDITED, PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

(1) DESCRIPTION OF TRANSACTION

On November 19, 2013, Amicus Therapeutics Inc. (“Amicus”) and its wholly-owned subsidiary CB Acquisition Corp., a Delaware corporation, entered into acquired an Agreement and Plan of Merger (the “Merger Agreement”) with Callidus Biopharma, Inc., a Delaware corporation, (“Callidus”) and a stockholders’ representative.  Pursuant to the Merger Agreement, at the closing on November 19, 2013, the Company acquired Callidus, a privately-held drug discovery company focused on enzyme replacement therapies for lysosomal storage disorders.

Under the terms of Merger Agreement, Amicus acquired Callidus and issued an aggregate of 7.2 million shares of its common stock, par value $0.01 per share (the “Common Stock”), to the former stockholders of Callidus (the “Closing Consideration”) which was valued at approximately $15 million on November 19, 2013.  In addition, the Company will be obligated to make additional payments to the former stockholders of Callidus upon the achievement by Callidus of certain regulatory approval and clinical milestones set forth in the Merger Agreement (such payments, in the aggregate, the “Milestone Consideration,” and together with the Closing Consideration, the “Merger Consideration”), provided that the aggregate Merger Consideration shall not exceed $130 million.

(2) BASIS OF PRESENTATION

The unaudited pro forma consolidated statements of operations are based on historical statements of operations of Amicus and Callidus, after giving effect to the acquisition of Callidus as if it occurred on January 1, 2012 for the year ended December 31, 2012 and the nine months ended September 30, 2013.

The unaudited pro forma balance sheet is based on the historical balance sheets of Amicus and Callidus, after giving effect to the acquisition of Callidus as if it occurred on September 30, 2013.

(3) PURCHASE PRICE ALLOCATION

The acquisition has been accounted for under the purchase method of accounting, which requires the Company to recognize the assets acquired and liabilities assumed and contingent consideration at their respective fair values on the acquisition date. The Company’s consolidated financial statements for the periods subsequent to the acquisition date reflect these values and Callidus’ results of operations.

The following table presents the allocation of the purchase consideration, including the contingent acquisition consideration payable, based on fair value on the acquisition date (in thousands):

Upfront equity payments	$	15,000
Contingent consideration payable	10,600
Total consideration	$	25,600
Cash and cash equivalents	$	363
Other assets	90
Property, plant and equipment	174
Acquired deferred tax assets	328
Intangible assets — in-process research and development	29,000
Total identifiable assets acquired	$	29,955
Accounts payable and accrued expenses	(276		)
Deferred tax liability	(11,583		)
Total liabilities assumed	$	(11,859	)
Net identifiable assets acquired	18,096
Goodwill	7,504
Net assets acquired	$	25,600

The deferred tax liability relates to the tax impact of future amortization or possible impairments associated with the identified intangible assets acquired, which are not deductible for tax purposes. The goodwill results from the recognition of the deferred tax liability on the intangible assets.

(4) ADJUSTMENTS TO PRO FORMA CONSOLIDATED BALANCE SHEET AS OF SEPTEMBER 30, 2013 AND THE STATEMENTS OF OPERATIONS FOR THE YEAR ENDED DECEMBER 31, 2012 AND NINE MONTHS ENDED SEPTEMBER 30, 2013 (UNAUDITED)

The adjustments to the pro forma consolidated statements of operations have been calculated as if the acquisition occurred on January 1, 2012 and are as follows (unaudited):

(A) To record the acquisition of the net assets of Callidus. Intangible assets of approximately $26.0 million are comprised of the intellectual property related to Callidus’ lead enzyme replacement therapy for Pompe disease that is in late preclinical development.  These intangible assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development efforts.

(B) To eliminate Callidus’ historical stockholders’ equity amounts.

(C) To reflect contingent consideration payable to the former Callidus stockholders that is included in long term liabilities.

(D) To reflect the deferred tax liability which relates to the tax impact of future amortization or possible impairments associated with the identified intangible assets acquired.

(E) To reclassify certain expense amounts to conform to current presentation.

(F) To reflect the estimated change in the fair value of the contingent consideration payable to former Callidus’ stockholders.

(G) To reflect the cumulative impact of the pro forma adjustments in the statements of operations.
