MIMEDX GROUP, INC.

NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE THREE MONTHS ENDED MARCH 31, 2015 AND 2014

1. Basis of Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) from interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X.  Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.  Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of Accounting Standards Updates (“ASU’’) to the FASB’s Accounting Standards Codification (“ASC”).  In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the results of operations for the periods presented have been included.  Operating results for the three months endedMarch 31, 2015 and 2014, are not necessarily indicative of the results that may be expected for the fiscal year.  The balance sheet at December 31, 2014, has been derived from the audited consolidated financial statements at that date, but does not include all of the information and footnotes required by GAAP for complete financial statements. 

You should read these condensed consolidated financial statements together with the historical consolidated financial statements of the Company for the year ended December 31, 2014, included in the Company's Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 13, 2015. 

The Company operates in one business segment, Regenerative Biomaterials, which includes the design, manufacture, and marketing of products and tissue processing services for the Wound Care, Surgical, Sports Medicine, Ophthalmic and Dental market categories. The Company's biomaterial platform technologies include tissue technologies, AmnioFix® and EpiFix®, and device technology, CollaFix™, which the Company has yet to commercialize.

2. Significant Accounting Policies

Please see Note 2 to the Company's Consolidated Financial Statements included in the Company’s Form 10-K for the fiscal year ended December 31, 2014, for a description of all significant accounting policies. 

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. 

Accounts Receivable

Accounts receivable represent amounts due from customers for which revenue has been recognized. Generally, the Company does not require collateral or any other security to support its receivables.

The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing receivables. The Company determines the allowance based on factors such as historical collection experience, customers' current creditworthiness, customer concentrations, age of accounts receivable balance and general economic conditions that may affect the customers' ability to pay. 

Inventories

Inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of market value. The Company assesses the valuation of its inventory on a periodic basis and makes adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand. The excess balance determined by this analysis becomes the basis for the Company's excess inventory charge. The Company's excess inventory review process includes analysis of sales forecasts, managing product rollovers and working with operations to maximize recovery of excess inventory.

Revenue Recognition

The Company sells its products through a combination of a direct sales force and independent stocking distributors and representatives in the U.S. and independent distributors in international markets. The Company recognizes revenue when title to the goods transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance. In cases where the Company utilizes distributors or ships product directly to the end user, it recognizes revenue upon shipment provided all other revenue recognition criteria have been met. A portion of the Company's revenue is generated from inventory maintained at hospitals or with the field representatives. For these products,

8

revenue is recognized at the time the product has been used or implanted. The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized.  

Patent Costs

The Company incurs certain legal and related costs in connection with patent applications for tissue-based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company and are included in Intangible Assets in the Condensed Consolidated Balance Sheets. The Company capitalized approximately $201,000 of patent costs during the first three months of 2015. The Company capitalized approximately $168,000 of patent costs during the first three months of 2014.

Treasury Stock

The Company accounts for the purchase of treasury stock under the cost method. Treasury stock which is reissued for the exercise of option grants and the issuance of restricted stock grants is accounted for on a first - in first - out (FIFO) basis.

Recent Accounting Pronouncements

The Company considers the applicability and impact of all ASUs issued effective and not yet effective. In May 2014, the Financial Accounting Standards Board issued ASU 2014-09, “Revenue Recognition - Revenue from Contracts with Customers” (ASU 2014-09) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. This update is effective for annual reporting periods beginning on or after December 15, 2016 and interim periods therein and requires expanded disclosures. We are currently assessing the impact the adoption of ASU 2014-09 will have on our condensed consolidated financial statements. All other ASUs issued effective and not yet effective for the three months endedMarch 31, 2015, and through the date of this report, were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's financial position or results of operations.

3. Liquidity and Management’s Plans

As of March 31, 2015, the Company had approximately $38,696,000 of cash and cash equivalents.  The Company reported total current assets of approximately $82,286,000 and current liabilities of approximately $18,460,000 as of March 31, 2015.  The Company believes that its anticipated cash from operating and financing activities, and existing cash and cash equivalents will enable the Company to meet its operational liquidity needs and fund its planned investing activities for the next twelve months.

4. Short Term Investments

Short term investments consist of approximately $6,000,000 of FDIC insured certificates of deposit held with various financial institutions as of March 31, 2015.

(a) On January 29, 2007, the Company acquired a license from Shriners Hospitals for Children and University of South Florida Research Foundation, Inc. in the amount of $996,000.  Within 30 days after the receipt by the Company of approval by the FDA allowing the sale of the first licensed product, the Company is required to pay an additional $200,000 to the licensor.  Due to its contingent nature, this amount is not recorded as a liability. The Company will also be required to pay a royalty of 3% on all commercial sales revenue from the licensed products. The Company is

10

also obligated to pay a $50,000 minimum annual royalty payment over the life of the license. As of March 31, 2015, this license had a remaining net book value of approximately $184,000.

(b) On January 5, 2011, the Company acquired Surgical Biologics, LLC.  As a result, the Company recorded intangible assets for Customer & Supplier Relationships of $3,761,000, Patents & Know-How of $7,690,000, Licenses of $13,000, Trade Names & Trademarks of $1,008,000 and In-Process Research & Development of $25,000.

	$	9,805

(a) Estimated amortization expense for the year ending December 31, 2015, includes only amortization to be recorded after March 31, 2015.

9. Net Income (Loss) Per Share

Basic net income (loss) per common share is computed using the weighted-average number of common shares outstanding during the period.  Diluted net income per common share is computed using the weighted-average number of common and dilutive common equivalent shares from stock options, restricted stock, and warrants using the treasury stock method. 

The following table sets forth the computation of basic and diluted net income (loss) per share (in thousands except share data):

	Three Months Ended March 31,
	2015		2014
Net income (loss)	$	4,087	$	(922	)
Denominator for basic earnings per share - weighted average shares	105,820,335		105,358,694
Effect of dilutive securities: Stock options, restricted stock, and warrants outstanding(a)	7,818,216		—
Denominator for diluted earnings per share - weighted average shares adjusted for dilutive securities	113,638,551		105,358,694
Income (loss) per common share - basic	$	0.04	$	(0.01	)
Income (loss) per common share - diluted	$	0.04	$	(0.01	)

11

(a) Securities outstanding that are included in the computation above, utilizing the treasury stock method for the three months ended March 31, 2015, are as follows:

Outstanding Stock Options	7,392,355
Outstanding Warrants	42,400
Restricted Stock Awards	383,461
	7,818,216

Securities outstanding for the three months ended March 31, 2014 were excluded from the computation of diluted earnings per share because they would have been anti-dilutive.

10. Equity

Stock Incentive Plans

The Company has three share-based compensation plans: the MiMedx Group, Inc. Assumed 2006 Stock Incentive Plan (the “2006 Plan”), the MiMedx Inc. 2007 Assumed Stock Plan (the “Assumed 2007 Plan”) and the MiMedx Group Inc. Amended and Restated Assumed 2005 Stock Plan (the “Assumed 2005 Plan”) which provide for the granting of qualified incentive and non-qualified stock options, stock appreciation awards and restricted stock awards to employees, directors, consultants and advisors. The awards are subject to a vesting schedule as set forth in each individual agreement. The Company intends to use only the 2006 Plan to make future grants. The number of assumed options under the Assumed 2005 Plan and Assumed 2007 Plan outstanding at March 31, 2015 totaled 195,000.  On July 28, 2014, the Company's shareholders approved 4,000,000 additional shares to be made available under the 2006 Plan, bringing the maximum number of shares of common stock that can be issued under the 2006 Plan to 26,500,000 at March 31, 2015.

Total unrecognized compensation expense related to granted stock options at March 31, 2015, was approximately $12,426,694 and will be charged to expense ratably through February 2018. 

The fair value of options granted by the Company is estimated on the date of grant using the Black-Scholes-Merton option-pricing model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate.  Expected volatilities are based on historical volatility of peer companies and other factors estimated over the expected term of the options.  The term of employee options granted is derived using the “simplified method,” which computes expected term as the mid point between the weighted average time to vesting and the contractual maturity. The simplified method was used due to the Company's lack of sufficient historical data to provide a reasonable basis upon which to estimate the expected term due to the limited period of time its equity shares have been publicly traded.  The term for non-employee options is generally based upon the contractual term of the option.  The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term or contractual term as described.

The assumptions used in calculating the fair value of options using the Black-Scholes-Merton option-pricing model are set forth in the following table:

	Three Months Ended March 31,
	2015	2014
Expected volatility	56.8- 58.1%	64.1 - 64.5%
Expected life (in years)	6.0	6.0
Expected dividend yield	—	—
Risk-free interest rate	1.57% - 1.66%	1.69% - 1.96%

The weighted-average grant date fair value for options granted during the three months endedMarch 31, 2015, was approximately $5.13.

Restricted Stock Awards                                                    

Activity with respect to restricted stock awards is summarized as follows: 

	Number of Shares		Weighted-Average Grant Date Fair Value
Unvested at January 1, 2015	1,228,898		$7.16
Granted	1,290,858		9.52
Vested	(232,691	)	6.54
Forfeited	(715	)	7.24
Unvested at March 31, 2015	2,286,350		$8.56

As of March 31, 2015, there was approximately $17,989,017 of total unrecognized stock-based compensation related to time-based, nonvested restricted stock.  That expense is expected to be recognized on a straight-line basis over a weighted-average

13

period of 2.6 years, which approximates the remaining vesting period of these grants. All shares noted above as unvested are considered issued and outstanding at March 31, 2015.

For the three months ended March 31, 2015 and 2014, the Company recognized stock-based compensation as follows (in thousands): 

	Three Months Ended March 31,
	2015		2014
Cost of sales	$	95	$	97
Research and development	186		160
Selling, general and administrative	3,652		2,115
	$	3,933	$	2,372

Warrants

As of March 31, 2015, the Company had 42,400 common stock warrants with an exercise price of $1.09 outstanding representing compensation to consultants and advisors in connection with previous debt offerings. The warrants expire in December 2016 and are classified as equity.

Treasury Stock

On May 12, 2014, the Company announced that its Board of Directors had authorized the repurchase of up to $10,000,000 of its common stock from time to time, through December 31, 2014. On December 12, 2014, the Board extended this program until December 31, 2015. On January 5, 2015, the Board increased the authorization under the program to $20,000,000. The timing and amount of future repurchases, if any, will depend upon the Company's stock price, economic and market conditions, regulatory requirements, and other corporate considerations. The Company may initiate, suspend or discontinue purchases under the stock repurchase program at any time.

For the three months ended March 31, 2015, the Company purchased 1,359,753 shares of its common stock for an aggregate purchase price of approximately $12,254,000 before brokerage commissions of approximately $41,000. As of March 31, 2015, the Company had approximately $2,162,000 remaining under the repurchase program.

Additionally, for the three months ended March 31, 2015, the Company reissued 1,369,108 shares from the Treasury for restricted stock grants and stock option exercises with an aggregate carrying value of $9,310,268.

11. Income taxes

The effective tax rates for continuing operations of 3.4% and (1.1%), respectively, for the three months ended March 31, 2015 and March 31, 2014, were determined using an estimated annual effective tax rate and after considering any discrete items for such periods. Due to a valuation allowance against the Company's U.S. deferred tax assets, the effective tax rate for the three months ended March 31, 2015, does not include the expense of the current period U.S. taxable income. A valuation allowance is recorded to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that a portion or none of the deferred tax assets will be realized.  After consideration of all the evidence, including reversal of deferred tax liabilities, future taxable income and other factors, management has determined that a full valuation allowance is necessary as of March 31, 2015. As a result, income tax expense for the three months ended March 31, 2015, is primarily due to income tax expense in certain state jurisdictions.

As a result of anticipated profitability for the year and positive trends in the foreseeable future, the Company may release all or a portion of this valuation allowance by the end of 2015. However, the exact timing and amount of the valuation allowance released are subject to change based on the level of profitability that the Company is able to actually achieve for the year and its visibility into future period results. The potential release of this valuation allowance during 2015 would have a material impact on the Company's recorded tax expense in the period of reversal. The Company will release this valuation allowance when management determines that it is more likely than not that its deferred tax asset will be realized.

FDA Untitled Letter and Related Litigation

Initially, MiMedx processed its tissue allografts in only one form, which was a sheet form. In 2011, MiMedx introduced a micronized form of its sheet allografts.

The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient. If an HCT/P meets the criteria for regulation solely under Section 361 of the Public Health Service Act (so-called “361 HCT/Ps”), no FDA review for safety and effectiveness under a drug, device, or biological product marketing application is required.

MiMedx believes that all of its tissue products qualify as 361 HCT/Ps. On August 28, 2013, however, the FDA issued an Untitled Letter alleging that the Company’s micronized allografts do not meet the criteria for regulation solely under Section 361 of the Public Health Service Act and that, as a result, MiMedx would need a biologics license to lawfully market the micronized products.

In November 2013, the FDA clarified the basis for its position regarding the micronized products. Specifically, the FDA explained its belief that “[c]ryo-milling cut, dehydrated amniotic/chorionic membrane results in a micron-sized powder and the loss of the tensile strength and elasticity that are essential characteristics of the original amniotic/chorionic tissue relating to its utility to function as a ‘physical membrane’ (i.e. covering, barrier).” The Company responded to the FDA that while it does not agree with the FDA’s position, it understands the FDA’s interest in further regulating this emerging technology. Accordingly, the Company proposed to the FDA that it would pursue the Investigational New Drug (“IND”) and Biologics License Application (“BLA”) process for certain micronized products, and, in parallel, also proposed to enter into negotiations with the

15

FDA on a plan to transition the micronized products to licensed biological products and continue to market the micronized products under specific conditions.

On July 22, 2014, the Company filed its first IND application with the FDA. The application was allowed, paving the way for a Phase IIB clinical trial of its micronized product for a specified indication of use in anticipation of a BLA, which the Company expects to submit at a future date.  The clinical trial is expected to enroll approximately 150 patients in 10 - 20 clinical sites in the U.S. The Company initiated the trial in March of 2015.

The Company also requested a transition agreement to allow it to continue to market its current micronized products for certain specified uses while pursuing one or more BLAs. The Agency continues to assert that the current form of the Company’s micronized products are more than minimally manipulated and therefore are not eligible for marketing solely under Section 361 of the Public Health Service Act. The Company has conducted tests and has engaged independent laboratories to conduct tests that confirm that tensile strength and modulus of elasticity are not diminished by the process used by the Company to create its micronized products.

On December 22, 2014, the FDA issued for comment “Draft Guidance for Industry: Minimal Manipulation of Human Cells, Tissues, and Cellular and Tissue-Based Products.” Essentially the draft guidance takes the same position with respect to micronized amniotic tissue that it took in the Untitled Letter to MiMedx 16 months earlier.

The period for submitting comments on the Draft Guidance expired on February 23, 2015. The Company has submitted comments to the Draft Guidance asserting that the Draft Guidance represents agency action that goes far beyond FDA’s statutory authority, is inconsistent with existing HCT/ P regulations and FDA’s prior positions, and is internally inconsistent and is scientifically unsound. Additionally, the Company asked the FDA to allow MiMedx to continue to market its micronized products until the guidance or regulations as the case may be have been fully vetted through a process of notice and comment rule making. Preliminarily, FDA has indicated that it intends to issue for comment Draft Guidance on homologous use later this year and that industry and other interested parties will have an opportunity to comment on both guidance documents as a whole at that time.

If the FDA does allow the Company to continue to market a micronized form of its sheet allografts either prior to or after finalization of the Draft Guidance, it may impose conditions, such as labeling restrictions and compliance with Current Good Manufacturing Practices (“cGMP”). It is also possible that the FDA will not allow the Company to market any form of a micronized product without a biologics license even prior to finalization of the Draft Guidance and could even require the Company to recall its micronized products. Revenues from micronized products comprised approximately 14% of the Company's revenues in 2014.

Following the publication of the Untitled Letter from the FDA regarding the Company’s micronized products in September 2013, the trading price of the Company’s stock dropped sharply and several purported class action lawsuits were filed against the Company and certain of its executive officers asserting violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s belief that its products were 361 HCT/Ps, including its micronized products. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. The case is currently in the discovery phase. The Company currently believes that the outcome of this litigation will not have a material adverse impact on the Company's financial position or results of operations.

OIG Subpoena And Other Shareholder Litigation

In the fourth quarter of 2014, the Company received a subpoena from the Office of Inspector General, U.S. Department of Health and Human Services, or OIG, in connection with a civil investigation into matters primarily related to the Company's sales and marketing activities. In March 2015, the Company received notice from the Department of Justice that it declined at that time to intervene in the qui tam action that gave rise to the issuance of a subpoena. While it is still possible that the qui tam action could be brought privately by the relator and the government could opt to intervene in the qui tam action at a later date, the Company currently believes that the outcome of this litigation will not have a material adverse impact on the Company's financial condition or results of operations.

On February 19, 2015, a separate purported class action lawsuit was filed against the Company and certain of its executive officers in the United States District Court for the Southern District of New York. The suit alleged violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the

16

Company’s receipt of the subpoena discussed above. On April 22, 2015, the plaintiffs voluntarily dismissed this purported class action lawsuit against the Company.

Patent Litigation

On April 22, 2014, the Company filed a patent infringement lawsuit against Liventa Bioscience, Inc. ("Liventa"), Medline Industries, Inc. ("Medline") and Musculoskeletal Transplant Foundation, Inc. ("MTF") for permanent injunctive relief and unspecified damages. In addition to the allegations of infringement of certain of MiMedx's patents, the lawsuit asserts that Liventa and Medline knowingly and willfully made false and misleading representations about their respective products to providers, patients, and in some cases, prospective investors. The suit was filed in the United States District Court for the Northern District of Georgia. In the suit, MiMedx asserts that Liventa (formerly known as AFCell Medical, Inc.), Medline and MTF infringed and continue to infringe certain of the Company’s patents relating to the MiMedx dehydrated human amnion/chorion membrane ("dHACM") allografts. MTF is the processor and Liventa and Medline are the distributors of the allegedly infringing products. On May 30, 2014, the defendants filed answers to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement, invalidity, laches and estoppel. MTF and Medline also filed counterclaims seeking declaratory judgments of non-infringement and invalidity. On May 16, 2014, the Company also filed a patent infringement lawsuit against Transplant Technology, Inc. d/b/a Bone Bank Allografts (“Bone Bank”) and Texas Human Biologics, Ltd. (“Biologics”) for permanent injunctive relief and unspecified damages. The lawsuit was filed in the United States District Court for the Western District of Texas. This lawsuit similarly asserts that Bone Bank and Biologics infringed certain of the Company’s patents through the manufacturing and sale of tissue graft products. The defendants have denied the allegations in the Complaint. They also have raised affirmative defenses of non-infringement and invalidity and filed counterclaims seeking declaratory judgments of non-infringement and invalidity. The lawsuits currently are in the discovery and claim construction phases. In addition to defending the pending district court litigations, to avoid the high burden of proof required to prove invalidity of the Company's patent claims in the district court litigation, the defendants have filed several requests for inter-partes review by the Patent Trial and Appeal Board seeking to invalidate some of the Company's patent claims.

On March 2, 2015, the Company filed a patent infringement lawsuit against Nutech Medical, Inc. (“Nutech”) and DCI Donor Services, Inc. (“DCI”) for permanent injunctive relief and unspecified damages.  This lawsuit has been filed in the United States District Court for the Northern District of Alabama.  The lawsuit alleges that Nutech and DCI have infringed and continue to infringe MiMedx’s patents through the manufacture, use, sale, and/or offering of their tissue graft product.  The lawsuit also asserts that Nutech knowingly and willfully made false and misleading representations about its products to customers and/or prospective customers. 

14. Subsequent Events

On April 27, 2015, the Company's Board of Directors increased the authorization under the share repurchase program from $20,000,000 to $30,000,000.

MiMedx® is the leading supplier of amniotic tissue allografts, having supplied over 400,000 allografts for application in the Wound Care, Surgical, Sports Medicine, Ophthalmic and Dental sectors of healthcare.

Recent Events

Draft Guidance

On December 22, 2014, the FDA issued for comment “Draft Guidance for Industry: Minimal Manipulation of Human Cells, Tissues, and Cellular and Tissue-Based Products.” Essentially, the draft guidance takes the same position with respect to micronized amniotic tissue that it took in the Untitled Letter to the Company 16 months earlier. The period for submitting comments on the Draft Guidance expired on February 23, 2015. The Company has submitted comments to the Draft Guidance asserting that the Draft Guidance represents agency action that goes far beyond FDA’s statutory authority, is inconsistent with existing HCT/ P regulations and FDA’s prior positions, and is internally inconsistent and scientifically unsound. Additionally, the Company asked the FDA to allow MiMedx to continue to market its micronized products until the guidance or regulations as the case may be have been fully vetted through a process of notice and comment rule making. Preliminarily, FDA has indicated that it intends to issue for comment Draft Guidance on homologous use later this year and that industry and other interested parties will have an opportunity to comment on both guidance documents as a whole at that time.

The FDA’s recent actions in regards to using draft guidance documents to effect change without notice and comment rulemaking have garnered the attention of Congress and industry.  In May 2014, Senators Lamar Alexander, Richard Burr, Orrin Hatch, and Johnny Isaakson wrote to then-FDA Commissioner Margaret Hamburg expressing concern over the use of draft guidances to make substantive policy changes.  One noted concern was that draft guidances are not being revised, finalized, or withdrawn in a timely manner, leaving FDA-regulated entities without certainty as to what FDA’s expectations are.  The Senators further remarked that “FDA issues guidance that seemingly does not take into account, or may even conflict with, the scientific community.”  May 6, 2014 Letter to Commissioner Hamburg at page 2.   On January 29, 2015, Senator Lamar Alexander and Senator Richard Burr jointly released their report, “Innovation for Healthier Americans: Identifying Opportunities for Meaningful Reform to Our Nation’s Medical Product Discovery and Development,” in which they express concern that the current FDA framework is stifling medical innovation and depriving patients of cutting-edge medical treatment. The report notes “[t]he disparity between the pace of scientific discovery and development outside of the FDA and the pace of growth in FDA’s scientific knowledge threatens America’s position as a global leader in medical innovation.”   Report at page 7.  Additionally, FDA’s recent Draft Guidance on minimal manipulation evoked wide-ranging commentary from industry, many of which were similar to the Company’s comments as described above. 

Sales to Government Accounts

In 2014, we provided products to Government accounts, including the Department of Veteran's Affairs, through a distributor relationship with AvKARE, Inc. ("AvKARE"), which is a veteran-owned General Services Administration Federal Supply Schedule (FSS) Contractor.   In 2014, we applied for, and in early 2015 received, our own FSS contract with a term through 2020, which allows us to sell directly to Government accounts. The initial term of the distribution agreement with AvKARE was due to expire in April 2015. In April 2015, we entered into an amendment to the distributor agreement with AvKARE to extend the distribution agreement through June 30, 2016, with the ability to further extend under certain circumstances. The amendment allows the Company to begin selling its products directly on the FSS. Ultimately, we intend to transition all of our Government sales to sales sold directly to Government accounts on the FSS.

OIG Subpoena And Related Shareholder Litigation

In the fourth quarter of 2014, the Company received a subpoena from the Office of Inspector General, U.S. Department of Health and Human Services, or OIG, in connection with a civil investigation into matters primarily related to the Company's sales and marketing activities. In March 2015, the Company received notice from the Department of Justice that it declined at

19

that time to intervene in the qui tam action that gave rise to the issuance of a subpoena. While it is still possible that the qui tam action could be brought privately by the relator and the government could opt to intervene in the qui tam action at a later date, the Company currently believes that the outcome of this litigation will not have a material adverse impact on the Company's financial condition or results of operations.

On February 19, 2015, a purported class action lawsuit was filed against the Company and certain of its executive officers in the United States District Court for the Southern District of New York. The suit alleged violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s receipt of the subpoena discussed above. On April 22, 2015, the plaintiffs voluntarily dismissed this purported class action lawsuit against the Company.

Results of Operations Comparison for the Three Months Ended March 31, 2015, to the Three Months Ended March 31, 2014

Revenue

Total revenue increased approximately $21.2 million, or 108%, to $40.8 million for the three months ended March 31, 2015, as compared to $19.6 million for the three months ended March 31, 2014. The increase in revenue as compared to the prior year is due to increased wound care sales of EpiFix® and surgical sales of AmnioFix®in both commercial and government accounts.

Tissue Processing Costs and Cost of Products Sold

Cost of products sold as a percentage of revenue improved to 12.6% from 15.2% as compared to prior year. The improvement was due primarily to the increase in direct sales revenue, improved product mix and higher production rates that absorb a greater percentage of fixed manufacturing costs.

Research and Development Expenses

The Company's research and development expenses (“R&D expenses”) increased approximately $0.4 million, or 31.7% , to $1.8 million during the three months ended March 31, 2015, compared to approximately $1.4 million in the prior year. The increase is primarily related to increased investments in clinical trials and personnel costs.

R&D expenses consist primarily of internal personnel costs, expenses of clinical trials, fees paid to external consultants, and the cost of supplies and instruments used in the Company's laboratories.

Selling, General and Administrative Expenses

Selling, General and Administrative expenses for the three months ended March 31, 2015, increased approximately $13.5 million to $29.3 million compared to $15.9 million for the three months ended March 31, 2014. Selling expense increases were driven by costs associated with expanding the Company's direct sales organization, increased commissions due to higher sales volume and an increase in share-based compensation. Additional spending increases included support costs related to medical reimbursement, including the Company's reimbursement hotline, information technology infrastructure to help manage the growth of the business, and legal costs due to patent litigation. Selling, General and Administrative expenses consist of personnel costs, professional fees, sales commissions, sales training costs, industry trade show fees and expenses, product promotion and product literature costs, facilities costs and other sales, marketing and administrative costs, depreciation and amortization, and share-based compensation.

Net Interest Expense

The Company recorded net interest expense of approximately $14,000 during the three months ended March 31, 2015, compared with approximately $21,000 of net interest expense during the three months ended March 31, 2014.  

Liquidity and Capital Resources

Revenue continues to increase quarter - over - quarter while management strives to maintain tight controls over spending. As of March 31, 2015, the Company had approximately $38.7 million of cash and cash equivalents. The Company reported total current assets of approximately $82.3 million and total current liabilities of approximately $18.5 million at March 31, 2015, which represents a current ratio of 4.5 as of March 31, 2015. Management believes that its anticipated cash from operating and financing activities, and existing cash and cash equivalents as well as its investments in certificates of deposit will enable the Company to meet its operational liquidity needs and fund its planned investing activities for the next year.

On May 12, 2014, the Company announced that its Board of Directors had authorized the repurchase of up to $10,000,000 of its common stock from time to time, through December 31, 2014. On December 12, 2014, the Board extended this program until December 31, 2015. On January 5, 2015, the Board increased the authorization under the program to $20,000,000.

For the three months ended March 31, 2015, the Company purchased approximately 1,359,753 shares of its common stock for an aggregate purchase price of approximately $12,254,000, before brokerage commissions of approximately $41,000 bringing the total amount spent under the program to approximately $17,838,000. As of March 31, 2015, the Company had approximately $2,162,000 remaining under the repurchase program.

On April 27, 2015, the authorization was further increased from $20,000,000 to $30,000,000. The timing and amount of future repurchases, if any, will depend upon the Company's stock price, economic and market conditions, regulatory requirements, and other corporate considerations. The Company may initiate, suspend or discontinue purchases under the stock repurchase program at any time.

Discussion of cash flows

Net cash from operations during the three months endedMarch 31, 2015, increased approximately $5.8 million to approximately $4.2 million compared to $1.6 million used in operating activities for the three months endedMarch 31, 2014, primarily attributable to the generation of net income compared to a net loss for the previous year and the increase in adjustments to net income for share-based compensation.

Net cash used in investing activities during the three months endedMarch 31, 2015, was $1.0 million compared to $0.6 million for 2014. Funds were used to purchase equipment to expand production capacity and capitalize patent application costs.

Net cash used in financing activities during the three months endedMarch 31, 2015, increased approximately $12.2 million to $11.0 million compared to $1.2 million of cash flows received from financing activities during the three months endedMarch 31, 2014. Cash flows used in financing activities during the three months include approximately $12.3 million for stock repurchases, partially offset by $1.3 million from the exercise of stock options. For the three months ended March 31, 2014, the Company received approximately $1.2 million in total from the exercise of warrants and stock options.

Due to the material amount of non-cash related items included in the Company results of operations, the Company reports an Adjusted EBITDA metric which provides management with a clearer view of operational use of cash (see the table below). The Company's Adjusted EBITDA for the three months ended March 31, 2015, was approximately $8.8 million which is an improvement of $6.8 million as compared to the three months ended March 31, 2014. The improvement was primarily the result of the generation of greater revenue and resulting net income compared to a net loss for the prior year.

22

Adjusted EBITDA is a non-GAAP measure. Non-GAAP financial measures are commonly used in the industry and are presented because management believes they provide relevant and useful information to investors. However, there are limitations to using these non-GAAP financial measures. Adjusted EBITDA is not indicative of cash provided or used by operating activities and may differ from comparable information provided by other companies. Adjusted EBITDA should not be considered in isolation, as an alternative to, or more meaningful than measures of financial performance determined in accordance with GAAP. The following table presents a reconciliation of Adjusted EBITDA to Net Income (loss) the most comparable financial measure reported under GAAP for the three months ended March 31, 2015 and 2014, (in thousands), respectively.

	Three Months Ended March 31,

Critical Accounting Policies

In preparing financial statements, the Company follows accounting principles generally accepted in the United States, which require the Company to make certain estimates and apply judgments that affect its financial position and results of operations.

Item 4. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), the Company carried out an evaluation of the effectiveness of the design and operation of its disclosure controls and procedures as of the end of the period covered by this report. This evaluation was carried out under the supervision and with the participation of Company management, including its Chief Executive Officer and Chief Financial Officer. Based upon that evaluation, the Company's Chief Executive Officer and Chief Financial Officer concluded that the Company's controls and procedures were effective as of the end of the period covered by this report.

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in the Company's reports filed or submitted under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in the Company's reports filed under the Exchange Act is accumulated and communicated to management, including the Company's Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding disclosures.

Changes in Internal Control over Financial Reporting

There was no change in the Company's internal control over financial reporting that occurred during the quarter ended March 31, 2015, that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

Limitations on the Effectiveness of Controls

The Company has confidence in its internal controls and procedures. Nevertheless, management, including the Company's Chief Executive Officer and Chief Financial Officer, does not expect that the Company's disclosure procedures and controls or its internal controls will prevent all errors or intentional fraud. An internal control system, no matter how well-conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of such internal controls are met. Further, the design of an internal control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all internal control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings

Following the publication of an Untitled Letter from the FDA regarding the Company’s micronized products in September 2013, the trading price of the Company’s stock dropped sharply and several purported class action lawsuits were filed against the Company and certain of its executive officers asserting violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s belief that its products were 361 HCT/Ps, including its micronized products. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. The case is currently in the discovery phase. The Company currently believes that the outcome of this litigation will not have a material adverse impact on the Company's financial condition or results of operations.

In the fourth quarter of 2014, the Company received a subpoena from the Office of Inspector General, U.S. Department of Health and Human Services, or OIG, in connection with a civil investigation into matters primarily related to the Company's sales and marketing activities. In March 2015, the Company received notice from the Department of Justice that it declined at that time to intervene in the qui tam action that gave rise to the issuance of a subpoena. While it is still possible that the qui tam action could be brought privately by the relator and the government could opt to intervene in the qui tam action at a later date, the Company currently believes that the outcome of this litigation will not have a material adverse impact on the Company's financial condition or results of operations.

On February 19, 2015, a separate purported class action lawsuit was filed against the Company and certain of its executive officers in the United States District Court for the Southern District of New York. The suit alleged violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s receipt of the subpoena discussed above. On April 22, 2015, the plaintiffs voluntarily dismissed this purported class action lawsuit against the Company.

24

On April 22, 2014, the Company filed a patent infringement lawsuit against Liventa Bioscience, Inc. ("Liventa"), Medline Industries, Inc. ("Medline") and Musculoskeletal Transplant Foundation, Inc. ("MTF") for permanent injunctive relief and unspecified damages. In addition to the allegations of infringement of MiMedx's patents, the lawsuit asserts that Liventa and Medline knowingly and willfully made false and misleading representations about their respective products to providers, patients, and in some cases, prospective investors. The suit was filed in the United States District Court for the Northern District of Georgia. In the suit, MiMedx asserts that Liventa (formerly known as AFCell Medical, Inc.), Medline and MTF infringed and continue to infringe certain of the Company’s patents relating to the MiMedx dehydrated human amnion/chorion membrane ("dHACM") allografts. MTF is the processor and Liventa and Medline are the distributors of the allegedly infringing products. On May 30, 2014, the defendants filed answers to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement, invalidity, laches and estoppel. MTF and Medline also filed counterclaims seeking declaratory judgments of non-infringement and invalidity. On May 16, 2014, the Company also filed a patent infringement lawsuit against Transplant Technology, Inc. d/b/a Bone Bank Allografts (“Bone Bank”) and Texas Human Biologics, Ltd. (“Biologics”) for permanent injunctive relief and unspecified damages. The lawsuit was filed in the United States District Court for the Western District of Texas. This lawsuit similarly asserts that Bone Bank and Biologics infringed the Company’s patents through the manufacturing and sale of tissue graft products. On July 10, 2014, the defendants filed an answer to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement and invalidity and filed counterclaims seeking declaratory judgments of non-infringement and invalidity. The lawsuits currently are in the discovery and claim construction phases. In addition to defending the claims in the pending district court litigations, defendants in each case, have challenged certain of the Company's patents in several inter-partes review proceedings to avoid the high burden of proof of proving invalidity by “clear and convincing evidence” in the district court litigations. An inter partes review is a request for a specialized group within the USPTO to review the validity of plaintiff’s patent claims. The Texas Defendants have challenged the validity of the Company's 8,597,687 and 8,709,494 patents; while the Georgia defendants have challenged the validity of the Company's 8,372,437 and 8,323,701 patents. The Company has successfully defeated an attempt by defendants to stay the litigation in Texas and Georgia pending the outcome of the inter-partes review.

On March 2, 2015, the Company filed a patent infringement lawsuit against Nutech Medical, Inc. (“Nutech”) and DCI Donor Services, Inc. (“DCI”) for permanent injunctive relief and unspecified damages.  This lawsuit has been filed in the United States District Court for the Northern District of Alabama.  The lawsuit alleges that Nutech and DCI have infringed and continue to infringe MiMedx’s patents through the manufacture, use, sale, and/or offering of their tissue graft product.  The lawsuit also asserts that Nutech knowingly and willfully made false and misleading representations about its products to customers and/or prospective customers. 

Item 1A. Risk Factors

There have been no material changes to the risk factors previously disclosed in the Company's Annual Report on Form 10-K for the year ended December 31, 2014.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On May 12, 2014, MiMedx Group, Inc. (the “Company”) announced that its Board of Directors had authorized the repurchase of up to $10,000,000 of its common stock from time to time through December 31, 2014. On December 12, 2014, the Board extended this program to December 31, 2015. On January 5, 2015, the Board increased the authorization under the program to $20,000,000 and on April 27, 2015, the authorization was further increased to $30,000,000. The timing and amount of future repurchases, if any, will depend upon the Company's stock price, economic and market conditions, regulatory requirements, and other corporate considerations. The Company may initiate, suspend or discontinue purchases under the stock repurchase program at any time. The following is a summary of the Company's stock repurchases, before brokerage commissions of approximately $41,000, for the quarter ended March 31, 2015:

EX-10.1

Exhibit 10.1

MIMEDX GROUP, INC.

2015 MANAGEMENT INCENTIVE PLAN (MIP)

I. Purpose

The 2015 MIP is designed to provide an incentive for key members of the MiMedx Group, Inc. (“MiMedx” or “Company”) management team to exceed the 2015 Business Plan and reward those management team members with deserving performance. The MiMedx Board of Directors (the “Board of Directors”) has complete authority to interpret the 2015 MIP, to prescribe, amend and rescind rules and regulations relating to it, and to make all other determinations necessary or advisable for the administration of the 2015 MIP (to the extent not inconsistent with Section 162(m) of the Code for payments to Covered Employees).

The portion of the 2015 MIP applicable to Covered Employees (as defined by Section 162(m) of the Internal Revenue Code (the “Code”)) is contingent upon the approval of the shareholders of the Company. No bonuses may be paid under the 2015 MIP to Covered Employees unless and until the shareholders of the Company approved the 2015 MIP. The provisions of the 2015 MIP shall be bifurcated, so that certain provisions of the 2015 MIP required in order to satisfy the requirements of Section 162(m) of the Code are only applicable to participants whose compensation is subject to 162(m) of the Code.

The goals of the 2015 MIP are:

1. To increase shareholder value.

2. To achieve and exceed the MiMedx 2015 Business Plan.

3. To reward key individuals for demonstrated performance that is sustained throughout the year.

4. To enhance the Company’s ability to be competitive in the marketplace for executive talent, and to attract, retain and motivate a high-performing and high-potential management team.

II. MIP Program Period

This program is in effect from January 1, 2015 through December 31, 2015. The program is subject to adjustment by the Company at any time during or after the program period. In the event of a program adjustment, an addendum will be published to inform eligible participants. No such adjustment may be made if it causes payments to Covered Employees to no longer qualify as qualified performance-based compensation under Section 162(m) of the Code.

III. MIP Participation and Eligibility

Participation and eligibility is determined by the Board of Directors with the Compensation Committee, as defined herein, approving the eligibility of Covered Employees. No individual is automatically included in the 2015 MIP. Only those individuals approved by the Board of Directors and confirmed in writing are eligible.

1

Verbal comments or promises to any employee or past practices are not binding on MiMedx or any of its divisions or subsidiaries in any manner.

Terminated Employees: If a participant terminates from the Company, the following guidelines will be used for all voluntary or involuntary terminations as well as terminations due to a Reduction in Force: Incentives are only earned by employees who are in good standing and employed on the date payment is made. Participants terminating employment prior to the date of payment are not eligible for any incentive payment, regardless of the reason for termination of employment.

First Time Participants: New management employees hired or promoted into an eligible position will be able to begin participating in the MIP on the first day of the first full month in the eligible position. The Base Bonus will be prorated based on the number of months employed in the eligible position. No incentives will be earned or paid for new hires beginning employment after September 30, 2015.

Existing Participants: Participants who transfer during the period January 1, 2015, through December 31, 2015, from one MIP eligible position to another MIP eligible position, having either a higher or lower Base Bonus, will begin participating at the new MIP level on the first day of the first full month in the new position. The participant’s Base Bonus will be prorated for the months employed in each eligible position.

Leave of Absence: Participants who have been on an approved leave of absence for medical or other reasons for greater than 60 cumulative days during the year will receive a prorated portion of their earned Base Bonus. The earned Base Bonus for participants on approved leaves of absence of less than 60 cumulative days will not be prorated based on the period of approved leave. Participants who have been on an approved leave of absence for medical or other reasons for greater than 120 cumulative days during the year will not be eligible to earn any amount of MIP for the year.

Covered Employees: The Compensation Committee shall retain discretion to name as a participant any otherwise-eligible Covered Employee hired or promoted after the commencement of the Plan.

IV. MIP Administration

The Board of Directors has the discretion, subject to the provisions of the 2015 MIP, to make or to select the manner of making all determinations with respect to the 2015 MIP to the extent not inconsistent with Section 162(m) for Covered Employees. The Board of Directors had delegated the administration of the MIP to the Compensation Committee of the Board of Directors (the “Compensation Committee”), who in turn, will approve and subsequently make recommendations to the Board of Directors for final approval of all determinations with respect the MIP. As delegated by the Board of Directors, the Compensation Committee shall have full authority to formulate adjustments and make interpretations under the 2015 MIP as it deems appropriate. As delegated, the Compensation Committee shall also be empowered to make any and all of the determinations not herein specifically authorized which may be necessary or desirable for the effective administration of the 2015 MIP. As delegated, the bonus amounts calculated under the 2015 MIP shall be paid only upon the Compensation Committee’s determination, in its sole discretion, that the participant is entitled to them. All matters of delegation of the 2015 MIP will be approved by the Compensation Committee prior to its recommendation to the Board of Directors for final approval. The Compensation Committee shall be comprised at all times solely of two or more directors who are “outside directors” within the meaning of Section 162(m) of the Code.

2

The Board of Directors may change the plan from time to time in any respect. All decisions made on behalf of the Company by the Board of Directors relative to the plan are final and binding. The determination of compliance with the individual objectives established under the plan for an employee shall be made by the Board of Directors in its sole discretion.

V. MIP Incentive Determination and Payment

The 2015 MIP provides for the determination of a Base Bonus expressed as a percentage of the participant’s annual salary in effect at the end of the program period or the end of each respective period when a participant transfers from one MIP eligible position to another.

Participants approved for MIP participation as of January 1, 2015, are eligible for a full year’s participation not subject to proration in accordance with the provisions hereof. All incentives earned under the MIP will be measured and paid annually.

VI. MIP Participants

The 2015 MIP participants include the Chief Executive Officer (the “CEO”), plus the direct reports to the CEO and Chief Operating Officer (the “COO”).

VII. MIP Method of Calculation

Each participant’s incentive will be calculated based on the achievement of financial targets and individual objectives. Base bonus for all MIP participants is divided into two financial components and an individual objectives component. 80% of the base bonus is allocated to 2015 Consolidated MiMedx Revenue performance (“Revenue”); 10% is allocated to 2015 Consolidated MiMedx Earnings Before Interest, Taxes, Depreciation, Amortization, and Share Based Compensation Expense performance (“Adjusted EBITDA”); and 10% is allocated to individual objectives performance (“Individual Objectives”).

The financial thresholds for 2015 Revenue and 2015 Adjusted EBITDA indicate the level of respective performance where partial payouts commence. Increased partial payouts are indicated for respective 2015 Revenue and 2015 Adjusted EBITDA performance above the financial threshold and below the financial target. The respective 2015 Revenue and 2015 Adjusted EBITDA targets indicate the point at which the respective target base bonuses are earned. Provided a minimum Adjusted EBITDA Threshold is achieved, each partial level of payout and target base bonus payout is determined independent of the other. Provided a minimum Adjusted EBITDA Threshold is achieved, at each respective level above of Adjusted EBITDA performance and Revenue performance a portion or the entire incentive amount allocated to individual objectives performance may be earned depending on the participant’s achievement of the individual objective(s).

All performance measures and/or metrics and performance goals will be established in writing and approved by the Compensation Committee and the Board of Directors no later than the earlier of (i) ninety (90) days following the start of the fiscal year to which they relate and (ii) before the lapse of twenty-five percent (25%) of the period to which they relate. All performance measures and/or metrics and performance goals must be uncertain of achievement at the time they are established, and the achievement of the performance measures

3

and/or metrics and performance goals must be determinable by a third party with knowledge of the relevant facts.

Following the end of the Program Period, management will provide documentation to the Compensation Committee confirming the degree of achievement of all performance measures and/or metrics and performance goals pertaining to the 2015 MIP. The Compensation Committee will review the documentation from management, and following its review, the Compensation Committee will certify, in writing, the achievement of such performance measures and/or metrics and performance goals prior to the approval of the Compensation Committee and its subsequent recommendation to the Board of Directors for final approval and payment in accordance with such achievement.

EBITDA Performance

MiMedx Adjusted EBITDA performance has 6 designated levels at which specific portions of the EBITDA component (up to 100% of the Adjusted EBITDA target) are funded for payout.

◦ Financial Gatekeeper: The Adjusted EBITDA component is a gatekeeper for the Revenue component and the individual objectives component. If Adjusted EBITDA performance is unfavorable to the Adjusted EBITDA Threshold, no payout for Adjusted EBITDA performance, as well as Revenue performance or individual objectives performance can be made. If Adjusted EBITDA performance is favorable to the Adjusted EBITDA Threshold, the Revenue component and the Individual Objectives component are paid out independent of and in addition to the Adjusted EBITDA component.

Revenue Performance

The Revenue performance has 6 designated levels at which specific portions of the Revenue component (up to 100% of the Revenue target) are funded for payout. The Revenue performance also has an additional 6 designated levels (levels 7 through 12 in the table below) above 100% of the Revenue target at which an excess bonus is funded for payout.

Revenue Performance Excess Bonus

If Revenue performance is greater than 100% of the Revenue Target (Level 6 in the Revenue performance table below), the participant may earn an excess bonus. The excess bonus is earned for each level of designated revenue performance at the excess percentage of the Revenue component plus the same excess percentage of the earned EBITDA component and the earned Individual Objectives component (levels 7 through 12 in the Revenue performance table below). Including the excess bonus, the total bonus cannot exceed two (2) times a participant’s Base Bonus amount.

Individual Objectives Performance

If Adjusted EBITDA performance is less than the Adjusted EBITDA Threshold (Level 1 in the EBITDA performance table below), no amounts can be earned for this component of the MIP. If Adjusted EBITDA performance is at or favorable to the Adjusted EBITDA Threshold (Level 1 in the EBITDA performance table below) the participant is eligible to earn a portion or all of the Base Bonus allocated to the Individual Objectives component.

Individual Objectives for the participants are reviewed and approved by the Compensation Committee and recommended for approval by the Board of Directors. The individual objectives are key operational measures

4

and/or major milestone outcomes that are specific the participant’s position and directly related to the overall achievement of the MiMedx Business Plan and/or the MiMedx Strategic Plan. The individual objectives for all participants will be limited to one or more of the following performance measures and/or metrics: (i) Revenue; (ii) EBITDA; (iii) Adjusted EBITDA; (iv) cash flow (v) Days Sales Outstanding (DSO); (vi) return on equity; (vii) return on assets; (viii) earnings per share; (ix) operations expense efficiency; (x) return on investment; (xi) return on capital; (xii) improvements in capital structure; (xiii) expense management; (xiv) profitability of an identifiable business unit or product; (xv) maintenance or improvement of profit margins; (xvi) total shareholder return; (xvii) market share; (xviii) working capital; (xix) efficiency ratios; (xx) comparison with stock market indices or performance of metrics with peer companies; and (xxi) achievement of performance measures consistent with the foregoing performance measures within a division group, product line, or sales channel. Individual performance objectives for Covered Employees can only be based on the specific business criteria described herein as is acceptable for qualified performance-based compensation under Section 162(m) of the Code.

If all of the individual objectives are achieved, the participant may earn the full Base Bonus amount allocated to the Individual Objectives component of the MIP. If some, but not all, of the individual objectives are attained, a partial amount of the Base Bonus allocated to the individual objectives component may be earned on a proportionate basis.

A table summary of the MIP calculations is as follows:

Adjusted EBITDA Performance and Portions of EBITDA Component Funded

◦ Adjusted EBITDA < Level 1 = no incentive earned for any MIP component

◦ Adjusted EBITDA at Level 1 = 10% of Adjusted EBITDA target bonus (plus earned Revenue and Individual Objectives)

◦ Adjusted EBITDA at Level 2 = 25% of Adjusted EBITDA target bonus (plus earned Revenue and Individual Objectives)

◦ Adjusted EBITDA at Level 3 = 50% of Adjusted EBITDA target bonus (plus earned Revenue and Individual Objectives)

◦ Adjusted EBITDA at Level 4 = 75% of Adjusted EBITDA target bonus (plus earned Revenue and Individual Objectives)

◦ Adjusted EBITDA at Level 5 = 90% of Adjusted EBITDA target bonus (plus earned Revenue and Individual Objectives)

◦ Adjusted EBITDA at Level 6 = 100% of Adjusted EBITDA target bonus (plus earned Revenue and Individual Objectives)

◦ Adjusted EBITDA > Level 6 = 100% of Adjusted EBITDA target bonus (plus earned Revenue and Individual Objectives)

▪ For Adjusted EBITDA performance greater that the Adjusted EBITDA target, an Excess Bonus may only be funded based upon Revenue performance greater than 100% of revenue target as described below.

Revenue Performance and Portions of Revenue Component Funded

◦ Revenue < Level 1 = no incentive earned for Revenue component.

5

◦ Revenue at Level 1 = 15% of Revenue target bonus (plus earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 2 = 40% of Revenue target bonus (plus earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 3 = 60% of Revenue target bonus (plus earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 4 = 80% of Revenue target bonus (plus earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 5 = 95% of Revenue target bonus (plus earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 7 = 110% of Revenue target bonus and 110% of earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 8 = 125% of Revenue target bonus and 125% of earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 9 = 140% of Revenue target bonus and 140% of earned Adjusted EBITDA and earned Individual Objectives)

◦ Revenue at Level 12 = 200% of Revenue target bonus and 200% of earned Adjusted EBITDA and earned Individual Objectives)

▪ The maximum MIP amount is limited to two (2) times the participant’s Base Bonus.

The Compensation Committee shall adjust the corporate and individual performance objectives as the Compensation Committee in its sole discretion may determine is appropriate in the event of unbudgeted acquisitions or divestitures or other unexpected fundamental changes in the business, any business unit or any product to fairly and equitably determine the bonus amounts and to prevent any inappropriate enlargement or dilution of the bonus amounts.  In that respect, the corporate and individual performance objectives may be adjusted to reflect, by way of example and not of limitation, (i) unanticipated asset write-downs or impairment charges, (ii) litigation or claim judgments or settlements thereof, (iii) changes in tax laws, accounting principles or other laws or provisions affecting reported results, (iv) accruals for reorganization or restructuring programs, or extraordinary non-reoccurring items as described in Accounting Principles Board Opinion No.  30 or as described in management’s discussion and analysis of the financial condition and results of operations appearing in the Annual Report on Form 10-K for the applicable year, (v) acquisitions or dispositions or (vi) foreign exchange gains or losses.  To the extent any such adjustments affect any bonus amounts, the intent is that the adjustments shall be in a form that allows the bonuses payable to Covered Employees to continue to meet the requirements of Section 162(m) of the Code for deductibility to the extent intended to constitute qualified performance-based compensation.

6

VIII. Maximum MIP Payment Amounts

The maximum potential amount to be earned by a participant is two (2) times the participant’s Base Bonus Amount. The determining annual base salary in the earned payout calculation is the annual base salary in effect at the end of the program period or the end of each respective period when a participant transfers from one MIP eligible position to another. In all cases, the maximum earned payout for the 2015 MIP for any one individual participant cannot exceed $750,000.

IX. Payment of Earned MIP Amounts

Amounts earned by participants will be paid following the Board of Directors meeting in late February or early March, and such payment date shall be paid between February 15,2016 and March 15,2016.

X. Compliance with Section 162 (m)

It is the intent of the Company that the 2015 MIP and any bonuses payable under the 2015 MIP to participants who are or may become persons whose compensation is subject to Section 162(m) of the Code and that are intended to constitute qualified performance-based compensation satisfy any applicable requirements of Section 162(m) of the Code to qualify as qualified performance-based compensation. Any provision, application or interpretation of the 2015 MIP inconsistent with this intent shall be disregarded or deemed to be amended to the extent necessary to conform to such requirements. The provisions of the 2015 MIP may be bifurcated by the Board of Directors upon recommendation by the Compensation Committee at any time, so that certain provisions of the 2015 MIP required in order to satisfy the requirements of Section 162(m) of the Code are only applicable to participants whose compensation is subject to 162(m) of the Code.

XI. Exemption from 409A

This Plan is intended to be exempt from the applicable requirements of Section 409A of the Code and shall be construed and interpreted in accordance therewith. The Committee may at any time amend, suspend or terminate this Plan, or any payments to be made hereunder, as necessary to be exempt from Section 409A of the Code. Notwithstanding the preceding, MiMedx shall be liable to any participant or any other person if the Internal Revenue Service or any court or other authority having jurisdiction over such matter determines for any reason that any bonus to be made under this Plan is subject to taxes, penalties or interest as a result of failing to be exempt from, or comply with, Section 409A of the Code. The bonuses under the Plan are intended to satisfy the exemption from Section 409A of the Code for “short-term deferrals.”

XII. MIP Miscellaneous

Nothing in the MIP shall be deemed to constitute a contract for the continuance of employment of the participants or bring about a change of status of employment. Neither the action of the Company in establishing this program, nor any provisions hereof, nor any action taken by the Company shall be construed as giving any employee the right to be retained in the employ of the Company for any period of time, or to be employed in any particular position, or at any particular rate of remuneration.

7

Further, nothing contained herein shall in any manner inhibit the day-to-day conduct of the business of the Company and its subsidiaries, which shall remain within the sole discretion of management of the Company; nor shall any requirements imposed by management or resulting from the conduct of the business of the Company constitute an excuse for, or waiver from, compliance with any goal established under this plan.

No persons shall have any right, vested or contingent, or any claim whatsoever, to be granted any award or receive any payment hereunder, except payments of awards determined and payable in accordance with the specific provisions hereof or pursuant to a specific and properly approved agreement regarding the granting or payment of an award to a designated individual.

Neither this program, nor any payments pursuant to this program, shall affect, or have any application to, any of the Company’s life insurance, disability insurance, PTO, medical or other related benefit plans, whether contributory or non-contributory on the part of the employee except as may be specifically provided by the terms of the benefit plan.

All payments pursuant to this program are in gross amounts less applicable withholdings.

MiMedx reserves the right to apply a participant’s incentive payment against any outstanding obligations owed to the Company.

[3] On January 29, 2007, the Company acquired a license from Shriners Hospitals for Children and University of South Florida Research Foundation, Inc. in the amount of $996,000. Within 30 days after the receipt by the Company of approval by the FDA allowing the sale of the first licensed product, the Company is required to pay an additional $200,000 to the licensor. Due to its contingent nature, this amount is not recorded as a liability. The Company will also be required to pay a royalty of 3% on all commercial sales revenue from the licensed products. The Company is also obligated to pay a $50,000 minimum annual royalty payment over the life of the license. As of March 31, 2015, this license had a remaining net book value of approximately $184,000

[4] Patents in Process consist of capitalized external legal and other registration costs in connection with internally developed tissue-based patents that are pending. Once issued, the costs associated with a given patent will be included in Patents & Know-How under intangible assets subject to amortization.

Accounting Policies [Abstract]

Significant Accounting Policies

Significant Accounting Policies

Please see Note 2 to the Company's Consolidated Financial Statements included in the Company’s Form 10-K for the fiscal year ended December 31, 2014, for a description of all significant accounting policies. 

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. 

Accounts Receivable

Accounts receivable represent amounts due from customers for which revenue has been recognized. Generally, the Company does not require collateral or any other security to support its receivables.

The allowance for doubtful accounts is the Company’s best estimate of the amount of probable credit losses in the Company’s existing receivables. The Company determines the allowance based on factors such as historical collection experience, customers' current creditworthiness, customer concentrations, age of accounts receivable balance and general economic conditions that may affect the customers' ability to pay. 

Inventories

Inventory is valued at standard cost, which approximates actual cost computed on a first-in, first-out basis, not in excess of market value. The Company assesses the valuation of its inventory on a periodic basis and makes adjustments to the value for estimated excess and obsolete inventory based on estimates about future demand. The excess balance determined by this analysis becomes the basis for the Company's excess inventory charge. The Company's excess inventory review process includes analysis of sales forecasts, managing product rollovers and working with operations to maximize recovery of excess inventory.

Revenue Recognition

The Company sells its products through a combination of a direct sales force and independent stocking distributors and representatives in the U.S. and independent distributors in international markets. The Company recognizes revenue when title to the goods transfers to customers, provided there are no material remaining performance obligations required of the Company or any matters of customer acceptance. In cases where the Company utilizes distributors or ships product directly to the end user, it recognizes revenue upon shipment provided all other revenue recognition criteria have been met. A portion of the Company's revenue is generated from inventory maintained at hospitals or with the field representatives. For these products, revenue is recognized at the time the product has been used or implanted. The Company records estimated sales returns, discounts and allowances as a reduction of net sales in the same period revenue is recognized.  

Patent Costs

The Company incurs certain legal and related costs in connection with patent applications for tissue-based products and processes. The Company capitalizes such costs to be amortized over the expected life of the patent to the extent that an economic benefit is anticipated from the resulting patent or alternative future use is available to the Company and are included in Intangible Assets in the Condensed Consolidated Balance Sheets. The Company capitalized approximately $201,000 of patent costs during the first three months of 2015. The Company capitalized approximately $168,000 of patent costs during the first three months of 2014.

Treasury Stock

The Company accounts for the purchase of treasury stock under the cost method. Treasury stock which is reissued for the exercise of option grants and the issuance of restricted stock grants is accounted for on a first - in first - out (FIFO) basis.

Recent Accounting Pronouncements

The Company considers the applicability and impact of all ASUs issued effective and not yet effective. In May 2014, the Financial Accounting Standards Board issued ASU 2014-09, “Revenue Recognition - Revenue from Contracts with Customers” (ASU 2014-09) that requires companies to recognize revenue when a customer obtains control rather than when companies have transferred substantially all risks and rewards of a good or service. This update is effective for annual reporting periods beginning on or after December 15, 2016 and interim periods therein and requires expanded disclosures. We are currently assessing the impact the adoption of ASU 2014-09 will have on our condensed consolidated financial statements. All other ASUs issued effective and not yet effective for the three months endedMarch 31, 2015, and through the date of this report, were assessed and determined to be either not applicable or are expected to have minimal impact on the Company's financial position or results of operations.

Income taxes

Income taxes

The effective tax rates for continuing operations of 3.4% and (1.1%), respectively, for the three months ended March 31, 2015 and March 31, 2014, were determined using an estimated annual effective tax rate and after considering any discrete items for such periods. Due to a valuation allowance against the Company's U.S. deferred tax assets, the effective tax rate for the three months ended March 31, 2015, does not include the expense of the current period U.S. taxable income. A valuation allowance is recorded to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that a portion or none of the deferred tax assets will be realized.  After consideration of all the evidence, including reversal of deferred tax liabilities, future taxable income and other factors, management has determined that a full valuation allowance is necessary as of March 31, 2015. As a result, income tax expense for the three months ended March 31, 2015, is primarily due to income tax expense in certain state jurisdictions.

As a result of anticipated profitability for the year and positive trends in the foreseeable future, the Company may release all or a portion of this valuation allowance by the end of 2015. However, the exact timing and amount of the valuation allowance released are subject to change based on the level of profitability that the Company is able to actually achieve for the year and its visibility into future period results. The potential release of this valuation allowance during 2015 would have a material impact on the Company's recorded tax expense in the period of reversal. The Company will release this valuation allowance when management determines that it is more likely than not that its deferred tax asset will be realized.

FDA Untitled Letter and Related Litigation

Initially, MiMedx processed its tissue allografts in only one form, which was a sheet form. In 2011, MiMedx introduced a micronized form of its sheet allografts.

The FDA has specific regulations governing human cells, tissues and cellular and tissue-based products, or HCT/Ps. An HCT/P is a product containing or consisting of human cells or tissue intended for transplantation into a human patient. If an HCT/P meets the criteria for regulation solely under Section 361 of the Public Health Service Act (so-called “361 HCT/Ps”), no FDA review for safety and effectiveness under a drug, device, or biological product marketing application is required.

MiMedx believes that all of its tissue products qualify as 361 HCT/Ps. On August 28, 2013, however, the FDA issued an Untitled Letter alleging that the Company’s micronized allografts do not meet the criteria for regulation solely under Section 361 of the Public Health Service Act and that, as a result, MiMedx would need a biologics license to lawfully market the micronized products.

In November 2013, the FDA clarified the basis for its position regarding the micronized products. Specifically, the FDA explained its belief that “[c]ryo-milling cut, dehydrated amniotic/chorionic membrane results in a micron-sized powder and the loss of the tensile strength and elasticity that are essential characteristics of the original amniotic/chorionic tissue relating to its utility to function as a ‘physical membrane’ (i.e. covering, barrier).” The Company responded to the FDA that while it does not agree with the FDA’s position, it understands the FDA’s interest in further regulating this emerging technology. Accordingly, the Company proposed to the FDA that it would pursue the Investigational New Drug (“IND”) and Biologics License Application (“BLA”) process for certain micronized products, and, in parallel, also proposed to enter into negotiations with the FDA on a plan to transition the micronized products to licensed biological products and continue to market the micronized products under specific conditions.

On July 22, 2014, the Company filed its first IND application with the FDA. The application was allowed, paving the way for a Phase IIB clinical trial of its micronized product for a specified indication of use in anticipation of a BLA, which the Company expects to submit at a future date.  The clinical trial is expected to enroll approximately 150 patients in 10 - 20 clinical sites in the U.S. The Company initiated the trial in March of 2015.

The Company also requested a transition agreement to allow it to continue to market its current micronized products for certain specified uses while pursuing one or more BLAs. The Agency continues to assert that the current form of the Company’s micronized products are more than minimally manipulated and therefore are not eligible for marketing solely under Section 361 of the Public Health Service Act. The Company has conducted tests and has engaged independent laboratories to conduct tests that confirm that tensile strength and modulus of elasticity are not diminished by the process used by the Company to create its micronized products.

On December 22, 2014, the FDA issued for comment “Draft Guidance for Industry: Minimal Manipulation of Human Cells, Tissues, and Cellular and Tissue-Based Products.” Essentially the draft guidance takes the same position with respect to micronized amniotic tissue that it took in the Untitled Letter to MiMedx 16 months earlier.

The period for submitting comments on the Draft Guidance expired on February 23, 2015. The Company has submitted comments to the Draft Guidance asserting that the Draft Guidance represents agency action that goes far beyond FDA’s statutory authority, is inconsistent with existing HCT/ P regulations and FDA’s prior positions, and is internally inconsistent and is scientifically unsound. Additionally, the Company asked the FDA to allow MiMedx to continue to market its micronized products until the guidance or regulations as the case may be have been fully vetted through a process of notice and comment rule making. Preliminarily, FDA has indicated that it intends to issue for comment Draft Guidance on homologous use later this year and that industry and other interested parties will have an opportunity to comment on both guidance documents as a whole at that time.

If the FDA does allow the Company to continue to market a micronized form of its sheet allografts either prior to or after finalization of the Draft Guidance, it may impose conditions, such as labeling restrictions and compliance with Current Good Manufacturing Practices (“cGMP”). It is also possible that the FDA will not allow the Company to market any form of a micronized product without a biologics license even prior to finalization of the Draft Guidance and could even require the Company to recall its micronized products. Revenues from micronized products comprised approximately 14% of the Company's revenues in 2014.

Following the publication of the Untitled Letter from the FDA regarding the Company’s micronized products in September 2013, the trading price of the Company’s stock dropped sharply and several purported class action lawsuits were filed against the Company and certain of its executive officers asserting violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s belief that its products were 361 HCT/Ps, including its micronized products. These cases have now all been removed to, and consolidated in, the United States District Court for the Northern District of Georgia. By order dated December 9, 2013, the Court approved the appointment of a lead plaintiff and a lead counsel. A Consolidated Amended Class Action Complaint, containing substantially the same causes of action and claims for relief as the initial complaints, was filed on January 27, 2014. The case is currently in the discovery phase. The Company currently believes that the outcome of this litigation will not have a material adverse impact on the Company's financial position or results of operations.

OIG Subpoena And Other Shareholder Litigation

In the fourth quarter of 2014, the Company received a subpoena from the Office of Inspector General, U.S. Department of Health and Human Services, or OIG, in connection with a civil investigation into matters primarily related to the Company's sales and marketing activities. In March 2015, the Company received notice from the Department of Justice that it declined at that time to intervene in the qui tam action that gave rise to the issuance of a subpoena. While it is still possible that the qui tam action could be brought privately by the relator and the government could opt to intervene in the qui tam action at a later date, the Company currently believes that the outcome of this litigation will not have a material adverse impact on the Company's financial condition or results of operations.

On February 19, 2015, a separate purported class action lawsuit was filed against the Company and certain of its executive officers in the United States District Court for the Southern District of New York. The suit alleged violations of the Securities Act of 1933 and the Securities Exchange Act of 1934 with respect to various statements and alleged omissions related to the Company’s receipt of the subpoena discussed above. On April 22, 2015, the plaintiffs voluntarily dismissed this purported class action lawsuit against the Company.

Patent Litigation

On April 22, 2014, the Company filed a patent infringement lawsuit against Liventa Bioscience, Inc. ("Liventa"), Medline Industries, Inc. ("Medline") and Musculoskeletal Transplant Foundation, Inc. ("MTF") for permanent injunctive relief and unspecified damages. In addition to the allegations of infringement of certain of MiMedx's patents, the lawsuit asserts that Liventa and Medline knowingly and willfully made false and misleading representations about their respective products to providers, patients, and in some cases, prospective investors. The suit was filed in the United States District Court for the Northern District of Georgia. In the suit, MiMedx asserts that Liventa (formerly known as AFCell Medical, Inc.), Medline and MTF infringed and continue to infringe certain of the Company’s patents relating to the MiMedx dehydrated human amnion/chorion membrane ("dHACM") allografts. MTF is the processor and Liventa and Medline are the distributors of the allegedly infringing products. On May 30, 2014, the defendants filed answers to the Complaint, denying the allegations in the Complaint. They also raised affirmative defenses of non-infringement, invalidity, laches and estoppel. MTF and Medline also filed counterclaims seeking declaratory judgments of non-infringement and invalidity. On May 16, 2014, the Company also filed a patent infringement lawsuit against Transplant Technology, Inc. d/b/a Bone Bank Allografts (“Bone Bank”) and Texas Human Biologics, Ltd. (“Biologics”) for permanent injunctive relief and unspecified damages. The lawsuit was filed in the United States District Court for the Western District of Texas. This lawsuit similarly asserts that Bone Bank and Biologics infringed certain of the Company’s patents through the manufacturing and sale of tissue graft products. The defendants have denied the allegations in the Complaint. They also have raised affirmative defenses of non-infringement and invalidity and filed counterclaims seeking declaratory judgments of non-infringement and invalidity. The lawsuits currently are in the discovery and claim construction phases. In addition to defending the pending district court litigations, to avoid the high burden of proof required to prove invalidity of the Company's patent claims in the district court litigation, the defendants have filed several requests for inter-partes review by the Patent Trial and Appeal Board seeking to invalidate some of the Company's patent claims.

On March 2, 2015, the Company filed a patent infringement lawsuit against Nutech Medical, Inc. (“Nutech”) and DCI Donor Services, Inc. (“DCI”) for permanent injunctive relief and unspecified damages.  This lawsuit has been filed in the United States District Court for the Northern District of Alabama.  The lawsuit alleges that Nutech and DCI have infringed and continue to infringe MiMedx’s patents through the manufacture, use, sale, and/or offering of their tissue graft product.  The lawsuit also asserts that Nutech knowingly and willfully made false and misleading representations about its products to customers and/or prospective customers.

Stock Incentive Plans

The Company has three share-based compensation plans: the MiMedx Group, Inc. Assumed 2006 Stock Incentive Plan (the “2006 Plan”), the MiMedx Inc. 2007 Assumed Stock Plan (the “Assumed 2007 Plan”) and the MiMedx Group Inc. Amended and Restated Assumed 2005 Stock Plan (the “Assumed 2005 Plan”) which provide for the granting of qualified incentive and non-qualified stock options, stock appreciation awards and restricted stock awards to employees, directors, consultants and advisors. The awards are subject to a vesting schedule as set forth in each individual agreement. The Company intends to use only the 2006 Plan to make future grants. The number of assumed options under the Assumed 2005 Plan and Assumed 2007 Plan outstanding at March 31, 2015 totaled 195,000.  On July 28, 2014, the Company's shareholders approved 4,000,000 additional shares to be made available under the 2006 Plan, bringing the maximum number of shares of common stock that can be issued under the 2006 Plan to 26,500,000 at March 31, 2015.

Activity with respect to the stock options is summarized as follows:

	Number  of Shares		Weighted- Average Exercise Price		Weighted-Average Remaining Contractual Term (in years)	Aggregate Intrinsic Value

The intrinsic value of the options exercised during the three months endedMarch 31, 2015, was approximately $6,402,516. 

Following is a summary of stock options outstanding and exercisable at March 31, 2015:

Total unrecognized compensation expense related to granted stock options at March 31, 2015, was approximately $12,426,694 and will be charged to expense ratably through February 2018. 

The fair value of options granted by the Company is estimated on the date of grant using the Black-Scholes-Merton option-pricing model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate.  Expected volatilities are based on historical volatility of peer companies and other factors estimated over the expected term of the options.  The term of employee options granted is derived using the “simplified method,” which computes expected term as the mid point between the weighted average time to vesting and the contractual maturity. The simplified method was used due to the Company's lack of sufficient historical data to provide a reasonable basis upon which to estimate the expected term due to the limited period of time its equity shares have been publicly traded.  The term for non-employee options is generally based upon the contractual term of the option.  The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for the period of the expected term or contractual term as described.

The assumptions used in calculating the fair value of options using the Black-Scholes-Merton option-pricing model are set forth in the following table:

	Three Months Ended March 31,
	2015	2014
Expected volatility	56.8- 58.1%	64.1 - 64.5%
Expected life (in years)	6.0	6.0
Expected dividend yield	—	—
Risk-free interest rate	1.57% - 1.66%	1.69% - 1.96%

The weighted-average grant date fair value for options granted during the three months endedMarch 31, 2015, was approximately $5.13.

Restricted Stock Awards                                                    

Activity with respect to restricted stock awards is summarized as follows: 

	Number of Shares		Weighted-Average Grant Date Fair Value
Unvested at January 1, 2015	1,228,898		$7.16
Granted	1,290,858		9.52
Vested	(232,691	)	6.54
Forfeited	(715	)	7.24
Unvested at March 31, 2015	2,286,350		$8.56

As of March 31, 2015, there was approximately $17,989,017 of total unrecognized stock-based compensation related to time-based, nonvested restricted stock.  That expense is expected to be recognized on a straight-line basis over a weighted-average period of 2.6 years, which approximates the remaining vesting period of these grants. All shares noted above as unvested are considered issued and outstanding at March 31, 2015.

For the three months ended March 31, 2015 and 2014, the Company recognized stock-based compensation as follows (in thousands):
