Borrower shall reimburse and indemnify, within 10 days after receipt of demand therefor, each
Lender for all Indemnified Taxes (including all Taxes and Other Taxes imposed by any jurisdiction on amounts payable under this
Section 2.5(c)) paid by such Lender, whether or not such Indemnified Taxes were correctly or legally asserted. A certificate of
the applicable Lender(s) setting forth the amounts to be paid thereunder and delivered to Borrower shall be conclusive, binding

shall provide to Borrower a properly completed and executed IRS Form W-9 certifying that such Lender is organized under the laws

which would modify or render invalid any claimed exemption or reduction. 


(e)                
If a Lender determines in good faith that it has received a refund from a Government Authority
of Taxes in respect of which the Borrower paid Additional Amounts or made a payment pursuant to Section 2.5(c), such Lender shall
promptly pay such refund to the Borrower, net of all out-of-pocket expense (including any Taxes imposed thereon) of such Lender
incurred in obtaining such refund, provided that the Borrower, upon the request of such Lender, agrees to repay the amount paid
over to the Borrower (plus any penalties, interest or other charges imposed by the relevant Governmental Authority) to such Lender
if such Lender is required to repay such refund to such Governmental Authority. Nothing in this Section shall require any Lender
to disclose any information it deems confidential (including, without limitation, its tax returns) to any Person, including Borrower.

shall be paid quarterly in arrears commencing the last Business Day on the first such calendar quarter end following the initial
Disbursement and on the last Business Day of each calendar quarter thereafter.


Section
2.8

available to the Lenders under the Financing Documents or otherwise, to the maximum extent permitted by applicable law, if the

(i)                  
The Financing Documents have been duly authorized, executed and delivered by the Borrower,
and constitute a valid, legal and binding obligation of the Borrower, enforceable in accordance with their terms, except as such
enforceability may be limited by (i) applicable insolvency, bankruptcy, reorganization, moratorium or other similar laws affecting
creditors’ rights generally, and (ii) applicable equitable principles (whether considered in a proceeding at law or in equity).
The execution, delivery and performance of the Financing Documents by the Borrower and the consummation of the transactions therein
contemplated will not (A) conflict with or result in a breach or violation of any of the terms or provisions of, or constitute
a default under, or result in the creation or imposition of any Lien upon any assets of the Borrower pursuant to any agreement

which any of the assets of the Borrower or any of its Subsidiaries is subject, (B) result in any violation of or conflict with,

and all Necessary Documents are valid and in full force and effect; and neither the Borrower nor any of its Subsidiaries has received
written notice of any revocation or modification of any of the Necessary Documents and neither the Borrower nor any of its Subsidiaries
has reason to believe that any of the Necessary Documents will not be renewed in the ordinary course, which revocation, modification
or non-renewal, individually or in the aggregate, would result in a Material Adverse Effect; and each of the Borrower and each
of its Subsidiaries is in compliance in all respects with all applicable federal, state, local and foreign laws, regulations, orders

There is then in effect a registration statement under the Securities Act covering such proposed
disposition and such disposition is made in accordance with said registration statement; or

Such Lender shall have notified the Borrower of the proposed disposition and, in the case
of a sale or transfer in a so-called “4(1) and a half” transaction, shall have furnished counsel for the Borrower with
an opinion of counsel, substantially in the form annexed as Exhibit C to the Warrant. The Borrower agrees that it will not require
an opinion of counsel with respect to transactions under Rule 144 or Rule 144A of the Securities Act.

laws affecting creditors’ rights generally, and (ii) applicable equitable principles (whether considered in a proceeding
at law or in equity).

Such Lender (A) has had reasonable opportunity to ask questions of and receive answers from
Borrower concerning the Financing Documents, (B) has been permitted access, to such Lender’s satisfaction, to the Borrower
SEC Reports, and (C) understands that the entry into the Financing Documents and the investment in the securities issued thereunder
is subject to risks as stated in the risk factors disclosed in the Borrower SEC Reports or as otherwise may be applicable to similar
investments and acknowledges that it has had an opportunity to review, and upon review, fully understands such risk factors.

the conflicts of laws principles thereof other than Sections 5-1401 and 5-1402 of the General Obligations Law of such State.


(a)                
 Each Party hereby irrevocably agrees that any legal action, suit or other proceeding arising
out of any Financing Document may be brought in the courts of the State of New York or of the United States of America for the
Southern District of New York. Each Party irrevocably consents to the service of any process in any such legal action, suit or

    	22





    	 



    

(b)                
Each Party irrevocably waives, to the fullest extent permitted by applicable law, any objection
which it may now or hereafter have to the laying of venue of any action, suit or other proceeding arising out of or relating to
any Financing Document, brought in the courts of the State of New York or in the United States District Court for the Southern

court arising out of or in connection with any Financing Document, be entitled to the benefit of any provision of law requiring
another Party in such suit, action or other proceeding to post security for the costs of another Party, or to post a bond or to
take similar action, each Party hereby irrevocably waive such benefit, in each case to the fullest extent now or hereafter permitted
under any applicable law.


Section
6.5                 
Successors and Assigns. This Agreement shall bind
and inure to the respective successors and assigns of the Parties, except that Borrower may not assign or otherwise transfer all
or any part of its rights under this Agreement or the Obligations (a “Transfer”) without the prior written consent
of the Lenders and the Lenders may not effect a Transfer to an entity that is an operating business (rather than an investment
vehicle) without the consent of the Borrower, which shall not be unreasonably withheld. Subject to the recording of an assignment
by a Lender in the Register pursuant to Section 1.4(b), (i) the assignee thereunder shall become a party hereto and, to the extent
that rights and obligations under Financing Documents have been assigned to such assignee pursuant to such assignment, shall have
the rights and obligations of a Lender, (ii) any applicable Note shall be transferred to such assignee through such entry and (iii)
the assignor thereunder shall, to the extent that its rights and obligations under this Agreement have been assigned by it pursuant
to such assignment, relinquish its rights (except for those surviving the payment in full of the Obligations) and be released from
its obligations under the Financing Documents, other than those relating to events or circumstances occurring prior to such assignment
(and, in the case of an assignment covering all or the remaining portion of an assigning Lender’s rights and obligations
under the Loan Documents, such Lender shall cease to be a party hereto). 


Section
6.6                 
Entire Agreement. The Financing Documents contain
the entire understanding of the Parties with respect to the matters covered thereby and supersede any and all other written and
oral communications, negotiations, commitments and writings with respect thereto. The provisions of this Agreement may be waived,
modified, supplemented or amended only by an instrument in writing signed by the authorized officer of each Party.



    	23





    	 



    

Section
6.7                 
Severability. If any provision of this Agreement
shall be invalid, illegal or unenforceable in any respect under any law, the validity, legality and enforceability of the remaining
provisions shall not in any way be affected or impaired thereby. The Parties shall endeavor in good faith negotiations to replace
the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible
to that of the invalid, illegal or unenforceable provision.


Section
6.8                 
Counterparts. This Agreement may be executed in several
counterparts, and by each Party on separate counterparts, each of which and any photocopies and facsimile copies thereof shall
be deemed an original, but all of which together shall constitute one and the same agreement.


Section
6.9                 
Survival. 


(a)                
This Agreement and all agreements, representations and warranties made in the Financing Documents,
and in any document, certificate or statement delivered pursuant thereto or in connection therewith shall be considered to have
been relied upon by the other Parties and shall survive the execution and delivery of this Agreement and the making of the Loan
hereunder regardless of any investigation made by any such other Party or on its behalf, and shall continue in force until all
amounts payable under the Financing Documents shall have been fully paid in accordance with the provisions thereof, and the Lenders
shall not be deemed to have waived, by reason of making the Loan, any Event of Default that may arise by reason of such representation
or warranty proving to have been false or misleading, notwithstanding that the Lenders may have had notice or knowledge of any
such Event of Default or may have had notice or knowledge that such representation or warranty was false or misleading at the time
the Disbursement was made.


(b)                
The obligations of the Borrower under Section 2.5 and the obligations of the Borrower
and the Lenders under this Article 6 shall survive and remain in full force and effect regardless of the consummation of the
transactions contemplated hereby, the repayment of the Loan, or the termination of this Agreement or any provision hereof.


Section
6.10             
Waiver. Neither the failure of, nor any delay on
the part of, any Party in exercising any right, power or privilege hereunder, or under any agreement, document or instrument mentioned
herein, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder,
or under any agreement, document or instrument mentioned herein, preclude other or further exercise thereof or the exercise of
any other right, power or privilege; nor shall any waiver of any right, power, privilege or default hereunder, or under any agreement,
document or instrument mentioned herein, constitute a waiver of any other right, power, privilege or default or constitute a waiver
of any default of the same or of any other term or provision. No course of dealing and no delay in exercising, or omission to exercise,
any right, power or remedy accruing to the Lenders upon any default under this Agreement, or any other agreement shall impair any
such right, power or remedy or be construed to be a waiver thereof or an acquiescence therein; nor shall the action of the Lenders
in respect of any such default, or any acquiescence by it therein, affect or impair any right, power or remedy of the Lenders in
respect of any other default. All rights and remedies herein provided are cumulative and not exclusive of any rights or remedies
otherwise provided by law.



    	24





    	 



    

Section
6.11             
Indemnity.


(a)                
The Parties shall, at all times, indemnify and hold each other harmless (the “Indemnity”)
and each of their respective directors, partners, officers, employees, agents, counsel and advisors (each, an “Indemnified
Person”) in connection with any losses, claims (including the cost of defending against such claims), damages, liabilities,
penalties, or other expenses arising out of, or relating to, the Financing Documents, the extension of credit hereunder or the
Loan or the use or intended use of the Loan, which an Indemnified Person may incur or to which an Indemnified Person may become
subject (each, a “Loss”). The Indemnity shall not apply to the extent that a court or arbitral tribunal with
jurisdiction over the subject matter of the Loss, and over the Lenders or the Borrower, as applicable, and such other Indemnified
Person that had an adequate opportunity to defend its interests, determines that such Loss resulted from the gross negligence or
willful misconduct of the Indemnified Person, which determination results in a final, non-appealable judgment or decision of a
court or tribunal of competent jurisdiction. The Indemnity is independent of and in addition to any other agreement of any Party
under any Financing Document to pay any amount to the Lenders or the Borrower, as applicable, and any exclusion of any obligation
to pay any amount under this subsection shall not affect the requirement to pay such amount under any other section hereof or under
any other agreement.


(b)                
Without prejudice to the survival of any other agreement of any of the Parties hereunder,
the agreements and the obligations of the Parties contained in this Section 6.11 shall survive the termination of each other
provision hereof and the payment of all amounts payable to the Lenders hereunder.


Section
6.12             
No Usury. The Financing Documents are hereby expressly
limited so that in no contingency or event whatsoever, whether by reason of acceleration or otherwise, shall the amount paid or
agreed to be paid to the Lenders for the Loan exceed the maximum amount permissible under applicable law. If from any circumstance
whatsoever fulfillment of any provision hereof, at the time performance of such provision shall be due, shall involve transcending
the limit of validity prescribed by law, then, ipso facto, the obligation to be fulfilled shall be reduced to the limit of such
validity, and if from any such circumstance the Lenders shall ever receive anything which might be deemed interest under applicable
law, that would exceed the highest lawful rate, such amount that would be deemed excessive interest shall be applied to the reduction
of the principal amount owing on account of the Loan, or if such deemed excessive interest exceeds the unpaid balance of principal
of the Loan, such deemed excess shall be refunded to the Borrower. All sums paid or agreed to be paid to the Lenders for the Loan
shall, to the extent permitted by applicable law, be deemed to be amortized, prorated, allocated and spread throughout the full
term of the Loan until payment in full so that the deemed rate of interest on account of the Loan is uniform throughout the term
thereof. The terms and provisions of this Section shall control and supersede every other provision of this Agreement and the Notes.



    	25





    	 



    

Section
6.13             
Further Assurances. From time to time, the Borrower
shall perform any and all acts and execute and deliver to the Lenders such additional documents as may be necessary or as requested
by the Lenders to carry out the purposes of any Financing Document or any or to preserve and protect the Lenders’ rights
as contemplated therein.

Notes to Condensed Financial Statements


March 31, 2012


(Unaudited)


 


 


1.  Organization and Basis of Presentation


 


MAKO Surgical Corp. (the “Company”
or “MAKO”) is an emerging medical device company that markets its advanced robotic arm solution and orthopedic implants
for orthopedic procedures called MAKOplasty®. The Company was incorporated in the State of Delaware on November 12,
2004 and is headquartered in Fort Lauderdale, Florida. The Company’s common stock trades on The NASDAQ Global Select
Market under the ticker symbol “MAKO.”


 


Basis of Presentation


 


In the opinion of management, the accompanying
unaudited condensed financial statements (“condensed financial statements”) of the Company have been prepared on a
basis consistent with the Company’s December 31, 2011 audited financial statements and include all adjustments, consisting
of only normal recurring adjustments, necessary to fairly state the information set forth herein. These condensed financial statements
have been prepared in accordance with the regulations of the Securities and Exchange Commission and, therefore, omit certain information
and footnote disclosure necessary to present the statements in accordance with accounting principles generally accepted in the
United States. These quarterly condensed financial statements should be read in conjunction with the audited financial statements
and notes thereto included in the Company’s annual report on Form 10-K for the year ended December 31, 2011 (the “Form
10-K”). The results of operations for the three months ended March 31, 2012 may not be indicative of the results to be expected
for the entire year or any future periods.


 


Liquidity and Operations


 


In executing its current business plan, the
Company believes its existing cash, cash equivalents and investment balances will be sufficient to meet its anticipated cash requirements
for at least the next twelve months. To the extent the Company’s available cash, cash equivalents and investment balances
are insufficient to satisfy its operating requirements, the Company will need to seek additional sources of funds, including selling
additional equity, debt or other securities or drawing on our available credit facility (see Note 8 for a discussion of the Facility
Agreement), or modifying its current business plan. The sale of additional equity or convertible debt securities may result in
dilution to the Company’s current stockholders. If the Company raises additional funds through the issuance of debt securities,
these securities may have rights senior to those of its common stock and could contain covenants that could restrict the Company’s
operations and ability to issue dividends. The Company may also require additional capital beyond its currently forecasted amounts.
Any required additional capital, whether forecasted or not, may not be available on reasonable terms, or at all. If the Company
is unable to obtain additional financing, the Company may be required to reduce the scope of, delay or eliminate some or all of
its planned research, development and commercialization activities, which could materially harm its business and results of operations.


 


Concentrations of Credit Risk and Other Risks and Uncertainties


 


Financial instruments that potentially subject
the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents, investments, and accounts
receivable. The Company’s cash and cash equivalents are held in demand and money market accounts at four large financial
institutions. The Company’s investments are held in a variety of interest bearing instruments, including notes and bonds
from U.S. government agencies and certificates of deposit at three large financial institutions. Such deposits are generally in
excess of insured limits. The Company has not experienced any historical losses on its deposits of cash and cash equivalents.


 



    	 



    	 



    

The Company may perform credit evaluations
of its customers’ financial condition and, generally, requires no collateral from its customers. The Company provides an
allowance for doubtful accounts when collections become doubtful but has not experienced any significant credit losses to date.


 


The Company is subject to risks common to emerging
companies in the medical device industry including, but not limited to: new technological innovations, dependence on key personnel,
dependence on key suppliers, changes in general economic conditions and interest rates, protection of proprietary technology, compliance
with new and established domestic and foreign government regulations and taxes, uncertainty of widespread market acceptance of
products, access to credit for capital purchases by our customers, product liability and the need to obtain additional financing.
The Company’s products include components subject to rapid technological change. Certain components used in manufacturing
have relatively few alternative sources of supply and establishing additional or replacement suppliers for such components cannot
be accomplished quickly. The inability of any of these suppliers to fulfill the Company’s supply requirements may negatively
impact future operating results. While the Company has ongoing programs to minimize the adverse effect of such uncertainty and
considers technological change in estimating the net realizable value of its inventory, uncertainty continues to exist.


 


The Company expects to derive most of its revenue
from capital sales of its RIO® Robotic Arm Interactive Orthopedic (“RIO”) system, current and future MAKOplasty
applications to the RIO system, recurring sales of implants and disposable products required for each MAKOplasty procedure, and
service plans that are sold with the RIO system. If the Company is unable to achieve broad commercial acceptance of MAKOplasty
or obtain regulatory clearances or approvals for future products, including other orthopedic products, its revenue would be adversely
affected and the Company would not become profitable.


 


The Company’s current versions of its
RIO system, its MAKOplasty partial knee and total hip arthroplasty applications, and its RESTORIS® MCK multicompartmental knee
implant systems and RESTORIS total hip implant systems have been cleared by the U.S. Food and Drug Administration (“FDA”).
Certain products currently under development by the Company will require clearance or approval by the FDA or other international
regulatory agencies prior to commercial sale. There can be no assurance that the Company’s products will receive the necessary
clearances or approvals. If the Company were to be denied any such clearance or approval or such clearance or approval were delayed,
it could have a material adverse impact on the Company.


 


2.  Summary of Significant Accounting Policies


 


Revenue Recognition


 


Revenue is generated: from (1) unit sales of
the Company’s RIO system and MAKOplasty applications (collectively, the “RIO system”), including associated instrumentation,
installation services and training; (2) sales of implants and disposable products utilized in MAKOplasty procedures; and (3) sales
of warranty and maintenance services. The Company recognizes revenue in accordance with ASC 605-10, Revenue Recognition,
when persuasive evidence of an arrangement exists, the fee is fixed or determinable, collection of the fee is probable and delivery
has occurred. For all sales, the Company uses either a signed agreement or a binding purchase order as evidence of an arrangement.


 



    	 



    	 



    

The Company’s multiple-element arrangements
are generally comprised of the following elements that qualify as separate units of accounting: (1) RIO system sales; (2) sales
of implants and disposable products; and (3) warranty and maintenance services on the RIO system hardware. The Company’s
revenue recognition policies generally result in revenue recognition at the following points:


 


	1.  	RIO system sales: Revenues related to RIO system sales are recognized upon installation of the system, training of at least one surgeon, which typically occurs prior to or concurrent with the RIO system installation, and customer acceptance, if required.
	 	 
	2.	Procedure revenue: Revenues from the sale of implants and disposable products utilized in MAKOplasty procedures are recognized at the time of sale (i.e., at the time of the related surgical procedure).
	 	 
	3.	Service revenue: Revenues from warranty and maintenance services, including extended warranty services, on the RIO system hardware are deferred and recognized ratably over the service period until no further obligation exists. Sales of the Company’s RIO system generally include a one-year warranty and maintenance obligation for services. Costs associated with providing warranty and maintenance services are expensed to cost of revenue as incurred.


 


Provisions for discounts and rebates to customers
are established as a reduction to revenue in the same period as the related sales are recorded.


 


A portion of the Company’s end-user customers
acquire the RIO system through a leasing arrangement with qualified third-party leasing companies. In these instances, the
Company sells the RIO system to the third-party leasing company, and the end-user customer enters into an independent leasing arrangement
with the third-party leasing company. The Company recognizes RIO system revenue for a RIO system sale to a third-party leasing
company on the same basis as a RIO system sale directly to an end-user customer. The Company sells implants and disposable products
utilized in MAKOplasty procedures directly to end-user customers under a separate agreement.


 


The Company’s domestic sales contracts
generally do not provide the customer with a right of return. If such a right is provided, all related revenues would be deferred
until such right expires or is waived. The Company’s domestic sales contracts generally do not provide the customer with
a customer acceptance period.  If such a right is provided, all related revenues would be deferred until the customer has
unconditionally accepted the RIO system.


 


Sales of implants and disposable products to
independent international distributors generally provide for a right of return. Accordingly, no revenue is recognized for these
sales until the right of return expires or is waived. Sales of the Company’s RIO system to international distributors generally
do not provide the distributor with a right of return. If such a right is provided, all related revenues would be deferred until
such right expires or is waived. The one-year warranty for RIO system sales to international distributors is limited to replacing
parts within the warranty period and does not provide for maintenance services. The Company accrues for the estimated costs of
providing the one-year warranty for RIO system sales to international distributors upon installation as a component of cost of
revenue - systems in the statements of operations.


 


The Company’s RIO system includes software
that is essential to the functionality of the product. Since the RIO system’s software and non-software components function
together to deliver the RIO system’s essential functionality, they are considered one deliverable that is excluded from the
software revenue recognition guidance. 


 



    	 



    	 



    

The Company allocates arrangement consideration
to the RIO systems and associated instrumentation, its implants and disposables and its warranty and maintenance services based
upon the relative selling-price method. Under this method, revenue is allocated at the time of sale to all deliverables based on
their relative selling price using a specific hierarchy. The hierarchy is as follows: vendor-specific objective evidence (“VSOE”)
of fair value of the respective elements, third-party evidence of selling price, or best estimate of selling price (“ESP”).


 


The Company allocates arrangement consideration
using ESP for its RIO system, ESP for its implants and disposables and VSOE of fair value for its warranty and maintenance services.
VSOE of fair value is based on the price charged when the element is sold separately. ESP is established by determining the price
at which the Company would transact a sale if the product was sold on a stand-alone basis. The Company determines ESP for its products
by considering multiple factors including, but not limited to, geographies, type of customer, and market conditions. The Company
regularly reviews ESP and maintains internal controls over the establishment and updates of these estimates.


 


Costs associated with establishing an accrual
for royalties covered by licensing arrangements related to the sale of RIO systems are expensed upon installation and are included
in cost of revenue - systems, in the statements of operations.


 


Deferred Revenue and Deferred Cost of Revenue


 


Deferred revenue consists of deferred service
revenue, deferred system revenue and deferred procedure revenue. Deferred service revenue results from the advance payment for
services to be delivered over a period of time, usually in one-year increments. Deferred system revenue arises from timing differences
between the installation of RIO systems and satisfaction of all revenue recognition criteria consistent with the Company’s
revenue recognition policy. Deferred procedure revenue arises from sales to independent international distributors which provide
for a right of return. No revenue is recognized for these sales until the right of return expires or is waived. Deferred revenue
expected to be realized within one year is classified as a current liability. Deferred cost of revenue consists of the direct costs
associated with the manufacture of RIO systems and implants and disposable products for which the revenue has been deferred in
accordance with the Company’s revenue recognition policy. The deferred revenue balance as of March 31, 2012 consisted primarily
of deferred service revenue for warranty and maintenance services on the RIO system hardware.


 


Inventory


 


Inventory is stated at the lower of cost or
market value on a first-in, first-out basis. Inventory costs include direct materials, direct labor and manufacturing overhead.
The Company reviews its inventory periodically to determine net realizable value and considers product upgrades in its periodic
review of realizability. The Company writes down inventory, if required, based on forecasted demand and technological obsolescence.
These factors are impacted by market and economic conditions, technology changes and new product introductions and require estimates
that may include uncertain elements.


 


Net Loss Per Share


 


The Company calculated net loss per share in
accordance with ASC 260, Earnings per Share. Basic earnings per share (“EPS”) is calculated by dividing the
net income or loss by the weighted average number of common shares outstanding for the period, without consideration for common
stock equivalents. Diluted EPS is computed by dividing the net income or loss by the weighted average number of common shares outstanding
for the period and the weighted average number of dilutive common stock equivalents outstanding for the period determined using
the treasury stock method. The following table sets forth potential shares of common stock that are not included in the calculation
of diluted net loss per share because to do so would be anti-dilutive as of the end of each period presented:

Recent Accounting Pronouncements 


 


In June 2011, the Financial Accounting Standards
Board issued new accounting guidance related to the presentation of comprehensive income that increases comparability between U.S.
generally accepted accounting principles and International Financial Reporting Standards. This guidance will require companies
to present the components of net income and other comprehensive income (“OCI”) either as one continuous statement or
as two consecutive statements, eliminating the option to present components of other comprehensive income as part of the statement
of changes in stockholders’ equity. This guidance is effective for the Company’s interim and annual periods beginning
January 1, 2012. The Company early adopted this guidance in 2011 and reports OCI in a separate statement. The adoption did
not have a material impact on the Company’s results of operations or financial position.


 


3.  Investments


 


The Company’s investments are classified
as available-for-sale. Available-for-sale securities are carried at fair value, with the unrealized gains and losses included in
other comprehensive gain (loss) within stockholders’ equity. Realized gains and losses, interest and dividends, amortization
of premium and discount on investment securities and declines in value determined to be other-than-temporary on available-for-sale
securities are included in other income, net. During the three months ended March 31, 2012 and 2011, realized gains and losses
recognized on the sale of investments were not significant. The cost of securities sold is based on the specific identification
method.


 


The amortized cost and fair value of short
and long-term investments, with gross unrealized gains and losses, were as follows:

Level 2 securities are priced using quoted
market prices and other observable market inputs for similar securities or discounted cash flow techniques. There have been no
transfers between Level 1 and Level 2 measurements during the three months ended March 31, 2012. No investments measured at fair
value on a recurring basis used Level 3 or significant unobservable inputs for the three months ended March 31, 2012.


 


Carrying amounts of certain of the Company’s
financial instruments, including cash and cash equivalents, investments, accounts receivable and other accrued liabilities approximate
fair value due to their short maturities or market rates of interest.


 



    	 



    	 



    

4.  Inventory


 


Inventory consisted of the following:


 


	(in thousands)	 	March 31,	 	 	December 31,	 
	 	 	2012	 	 	2011

	Total inventory	 	$	23,248	 	 	$	19,529	 


 


The Company reviews its inventory periodically
to determine net realizable value and considers product upgrades in its periodic review of realizability. Depending on demand for
the Company’s products and technical obsolescence, future write-offs of the Company’s inventory may occur.


 


5.  Commitments and Contingencies


 


Purchase Commitments


 


At March 31, 2012, the Company was committed
to make future purchases for inventory and other items that occur in the ordinary course of business under various purchase arrangements
with fixed purchase provisions aggregating $16.5 million.


 


Contingencies


 


The Company accrues a liability for legal contingencies
when it believes that it is both probable that a liability has been incurred and that it can reasonably estimate the amount of
the loss. The Company reviews these accruals and adjusts them to reflect ongoing negotiations, settlements, rulings, advice of
legal counsel and other relevant information. To the extent new information is obtained and the Company's views on the probable
outcomes of claims, suits, assessments, investigations or legal proceedings change, changes in the Company's accrued liabilities
would be recorded in the period in which such determination is made. For the matters referenced below, the amount of liability
is not probable or the amount cannot be reasonably estimated; and, therefore, accruals have not been made. In addition, in accordance
with the relevant authoritative guidance, for matters which the likelihood of material loss is at least reasonably possible, the
Company provides disclosure of the possible loss or range of loss; however, if a reasonable estimate cannot be made, the Company
will provide disclosure to that effect.


 


The Company is a defendant in various litigation
matters generally arising in the normal course of business. Although it is difficult to predict the ultimate outcomes of these
cases, the Company believes that it is not reasonably possible that the ultimate outcomes will materially and adversely affect
its business, financial position, results of operations or cash flows.


 



    	 



    	 



    

6.  Stockholders’ Equity


 


Preferred Stock


 


As of March 31, 2012 and December 31, 2011,
the Company was authorized to issue 27,000,000 shares of $0.001 par value preferred stock. As of March 31, 2012 and December
31, 2011, there were no shares of preferred stock issued or outstanding.


 


Common Stock


 


As of March 31, 2012 and December 31, 2011,
the Company was authorized to issue 135,000,000 shares of $0.001 par value common stock. Common stockholders are entitled to dividends
as and if declared by the Board of Directors, subject to the rights of holders of all classes of stock outstanding having priority
rights as to dividends. There have been no dividends declared to date on the common stock. The holder of each share of common stock
is entitled to one vote.


 


Stock Option Plans and Stock-Based Compensation


 


The Company recognizes compensation expense
for its stock-based awards in accordance with ASC 718, Compensation-Stock Compensation. ASC 718 requires the recognition
of compensation expense, using a fair value based method, for costs related to all stock-based payments including stock options.
ASC 718 requires companies to estimate the fair value of stock-based payment awards on the date of grant using an option-pricing
model.


 


During the three months ended March 31, 2012
and 2011, stock-based compensation expense was $2.7 million and $2.3 million, respectively. Included within stock-based compensation
expense for the three months ended March 31, 2012 were $2.2 million related to stock option grants, $386,000 related to restricted
stock granted to the Company’s CEO at various dates from 2009 through 2011, and $125,000 related to employee stock purchases
under the 2008 Employee Stock Purchase Plan.


 


The Company’s 2004 Stock Incentive Plan
(the “2004 Plan”), its 2008 Omnibus Incentive Plan (the “2008 Plan,” and together with the 2004 Plan, the
“Plans”), and its 2008 Employee Stock Purchase Plan are described in the notes to financial statements in the Form
10-K. Generally, the Company’s outstanding stock options vest over four years. Stock options granted to certain non-employee
directors generally vest over one year. Continued vesting typically terminates when the employment or consulting relationship ends.
Vesting generally begins on the date of grant.


 


The 2008 Plan contains an evergreen provision
whereby the authorized shares increase on January 1st of each year in an amount equal to the least of (1) 4% of the total number
of shares of the Company’s common stock outstanding on December 31st of the preceding year, (2) 2.5 million shares and (3)
a number of shares determined by the Company’s Board of Directors that is lesser than (1) and (2). The number of additional
shares authorized under the 2008 Plan on January 1, 2012 was approximately 1,676,000.


 


Under the terms of the Plans, the maximum term
of options intended to be incentive stock options granted to persons who own at least 10% of the voting power of all outstanding
stock on the date of grant is 5 years. The maximum term of all other options is 10 years. Options issued under the 2008
Plan that are forfeited or expire will again be made available for issuing grants under the 2008 Plan. Options issued under the
2004 Plan that are forfeited or expire will not be made available for issuing grants under the 2008 Plan. All future equity awards
will be made under the Company’s 2008 Plan.


 



    	 



    	 



    

Activity under the Plans is summarized as follows:


 


	(in thousands, except per share data)	 	 	 	 	Outstanding Options	 
	 	 	Shares/Options 
 Available 
 For Grant	 	 	Number of 
 Options	 	 	Weighted

	Balance at March 31, 2012	 	 	1,100	 	 	 	5,541	 	 	 	16.29	 


 


The Company records stock-based compensation
expense on a straight-line basis over the vesting period. As of March 31, 2012, there was total unrecognized compensation cost
of $32.1 million, net of estimated forfeitures, related to non-vested stock-based payments (including stock option grants, restricted
stock grants and compensation expense relating to shares issued under the 2008 Employee Stock Purchase Plan). The unrecognized
compensation cost will be adjusted for future changes in estimated forfeitures, and is expected to be recognized over a remaining
weighted average period of 3.0 years as of March 31, 2012.


 


The estimated grant date fair values of the
employee stock options were calculated using the Black-Scholes valuation model, based on the following assumptions:




 


	 	 	Three Months Ended March 31,	 
	 	 	2012	 	 	2011	 
	Risk-free interest rate	 	 	1.35% - 1.40%	 	 	 	2.71% - 2.92%	 
	Expected life	 	 	6.25 years	 	 	 	6.25 years	 
	Expected dividends	 	 	―	 	 	 	―	 
	Expected volatility	 	 	48.49% - 48.62%	 	 	 	49.87% - 50.12%	 


 


During the three months ended March 31, 2012,
2,278 shares of common stock were surrendered by the CEO to the Company to cover payroll taxes associated with the taxable income
from the vesting of restricted stock previously granted to the CEO. As of March 31, 2012, 1,064,387 shares of restricted stock
granted to the CEO were issued and outstanding.


 


Warrants


 


In December 2004, the Company issued warrants
to purchase 462,716 shares of common stock at a purchase price of $0.03 per share. The warrants were immediately exercisable at
an exercise price of $3.00 per share, with the exercise period expiring in December 2014. As of March 31, 2012, 310,872 warrants
were outstanding and exercisable.                



 


In October 2008, the Company issued warrants
to purchase 1,290,323 shares of common stock at a purchase price of $0.125 per share and an exercise price of $7.44 per share.
The warrants became exercisable on April 29, 2009 and have a seven-year term. As of March 31, 2012, 598,741 warrants were outstanding
and exercisable.


 



    	 



    	 



    

In October 2008, the Company issued warrants
to purchase 322,581 shares of common stock at a purchase price of $0.125 per share and an exercise price of $6.20 per share. These
warrants became exercisable on December 31, 2009 and have a seven-year term. As of March 31, 2012, 143,157 warrants were outstanding
and exercisable.


 


See Note 8 for a discussion of warrants issued
after March 31, 2012.


 


7.  Income Taxes


 


The Company accounts for income taxes under
ASC 740, Income Taxes. Deferred income taxes are determined based upon differences between financial reporting and income
tax bases of assets and liabilities and are measured using the enacted income tax rates and laws that will be in effect when the
differences are expected to reverse. The Company recognizes any interest and penalties related to unrecognized tax benefits as
a component of income tax expense.


 


Due to uncertainty surrounding realization
of the deferred income tax assets in future periods, the Company has recorded a 100% valuation allowance against its net deferred
tax assets. If it is determined in the future that it is more likely than not that the deferred income tax assets are realizable,
the valuation allowance will be reduced.


 


8.  Subsequent Event


 


On May 7, 2012, the Company entered into a
Facility Agreement with affiliates of Deerfield Management Company, L.P. (“Deerfield”), pursuant to which Deerfield
agreed to loan the Company up to $50 million, subject to the terms and conditions set forth in the Facility Agreement. Under
the terms of the agreement, the Company has the flexibility, but is not required, to draw down on the Facility Agreement in $10 million
increments at any time until May 15, 2013. The Company was not required to pay an upfront transaction fee to Deerfield under the
Facility Agreement.


 


Any amounts drawn under the Facility Agreement
accrue interest at a rate of 6.75% per annum and will be secured by all of the Company’s assets excepting only the Company’s
intellectual property assets. Accrued interest is payable quarterly in cash. The Company has the right to prepay any amounts owed
without penalty. All principal amounts outstanding under the Facility Agreement are payable on the third anniversary of each draw.
If no funds have been drawn under the Facility Agreement by May 15, 2013, the Company is required to pay Deerfield a fee of $1.0
million. As of May 7, 2012, the Company has not drawn any amounts under the Facility Agreement.


 


In connection with the execution of the Facility
Agreement, on May 7, 2012, the Company issued to Deerfield warrants to purchase 275,000 shares of the Company’s common stock
at an exercise price equal to a 20% premium to the mean closing price of the Company’s common stock over the 20 trading days
beginning on May 8, 2012. As noted above, the Company has the right to draw down on the Facility Agreement one or more cash disbursements
in the minimum amount of $10 million per disbursement. Each $10 million disbursement shall be accompanied by the issuance
to Deerfield of warrants to purchase 140,000 shares of common stock, at an exercise price equal to a 20% premium to the mean closing
price of the Company’s common stock over the 5 trading days following receipt by Deerfield of the draw notice. If the Company,
in its discretion, elects to draw down the entire $50 million available under the Facility Agreement, the Company will have
issued warrants to purchase a total of 975,000 shares of its common stock. The warrants expire seven years from their issuance.

	Warrant to Purchase
                     shares	Warrant Number 


 


Warrant to Purchase Common Stock

of

MAKO Surgical Corp.


THIS CERTIFIES that ____________ or any subsequent holder hereof
(“Holder”) has the right to purchase from MAKO Surgical Corp., a Delaware corporation, (the “Company”),
________ (______) fully paid and nonassessable shares of the Company’s common stock, $0.001 par value per share (“Common
Stock”), subject to adjustment as provided herein, at a price equal to the Exercise Price as defined in Section 3 below,
at any time during the Term (as defined below).


Holder agrees with the Company that this Warrant to Purchase Common
Stock of the Company (this “Warrant” or this “Agreement”) is issued and all rights hereunder shall be held
subject to all of the conditions, limitations and provisions set forth herein.


1. Date
of Issuance and Term.


This Warrant shall be deemed to be issued on May 7, 2012 (“Date
of Issuance”). The term of this Warrant begins on the Date of Issuance and ends at 5:00 p.m., New York City time, on the
date that is seven (7) years after the Date of Issuance (the “Term”). This Warrant was issued in conjunction with that
certain Facility Agreement (the “Facility Agreement”) and the Registration Rights Agreement (“Registration Rights
Agreement”) by and between the Company, Holder and __________, each dated May 7, 2012, entered into in conjunction herewith.


Notwithstanding anything herein to the contrary, the Company shall
not issue to the Holder, and the Holder may not acquire, a number of shares of Common Stock upon exercise of this Warrant to the
extent that, upon such exercise, the number of shares of Common Stock then beneficially owned by the Holder and its Affiliates
and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes
of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (including shares held
by any “group” of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership
of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the
limitation set forth herein) would exceed 9.985% of the total number of shares of Common Stock then issued and outstanding (the
“9.985% Cap”), provided, however, that the 9.985% Cap shall not apply with respect to the issuance of shares of Common
Stock pursuant to a Cashless Major Exercise (as defined below) in connection with a Major Transaction (as defined below) covered
by the provisions of Section 5(c)(i)(A)(1) below in which the Company is not the surviving entity (a “Non-Surviving Change
of Control Transaction”) to the extent that the number of shares beneficially owned by the Holder and its affiliates in the
successor entity immediately following consummation of such Non-Surviving Change of Control Transaction does not exceed 9.985%
of the outstanding common stock of such successor entity and provided, further, that the 9.985% Cap shall only apply to the extent
that the Common Stock is deemed to constitute an “equity security” pursuant to Rule 13d-1(i) promulgated under the
Exchange Act. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and
applicable regulations of the Securities and Exchange Commission (the “SEC”), and the percentage held by the Holder
shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. Upon the written request
of the Holder, the Company shall, within two (2) Trading Days, confirm orally and in writing to the Holder the number of shares
of Common Stock then outstanding.



    	 



    	 



    

“Affiliate” means any person or entity that, directly
or indirectly through one or more intermediaries, controls or is controlled by or is under common control with a person or entity,
as such terms are used in and construed under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”).
With respect to a Holder of Warrants, any investment fund or managed account that is managed on a discretionary basis by the same
investment manager as such Holder will be deemed to be an Affiliate of such Holder.


“Holder” means ______ and any transferee or assignee
pursuant to the terms of this Warrant.


2. Exercise.


(a) Manner
of Exercise. Beginning on the twenty-first (21st) Trading Day following the Date of Issuance and continuing during
the Term, this Warrant may be Exercised as to all or any lesser number of whole shares of Common Stock covered hereby (the “Warrant
Shares” or the “Shares”) upon surrender of this Warrant, with the Exercise Form attached hereto as Exhibit A
(the “Exercise Form”) duly completed and executed, together with the full Exercise Price (as defined below, which may
be satisfied by a Cash Exercise or a Cashless Exercise, as each is defined below) for each share of Common Stock as to which this
Warrant is Exercised, at the office of the Company, 2555 Davie Road, Fort Lauderdale, FL 33317, Phone: (954) 927-2044, Fax:
(954) 707-5360, electronic mail:adminteam@makosurgical.com), or at such other office or agency as the Company may designate
in writing, by overnight mail, with an advance copy of the Exercise Form sent to the Company by facsimile or electronic mail (such
surrender and payment of the Exercise Price hereinafter called the “Exercise” of this Warrant).


(b) Date
of Exercise. The “Date of Exercise” of the Warrant shall be defined as the date that the Exercise Form attached
hereto as Exhibit A, completed and executed, is sent by facsimile or electronic mail to the Company, provided that
the original Warrant and Exercise Form are received by the Company and the Exercise Price is satisfied, each as soon as practicable
thereafter but in no event later than two (2) business days following the date of such facsimile or electronic mail. Alternatively,
the Date of Exercise shall be defined as the date the original Exercise Form is received by the Company, if Holder has not sent
advance notice by facsimile or electronic mail. Upon delivery of the Exercise Form to the Company by facsimile, electronic mail
or otherwise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with
respect to which this Warrant has been Exercised, irrespective of the date such Warrant Shares are credited to the Holder’s
Depository Trust Company (“DTC”) account or the date of delivery of the certificates evidencing such Warrant Shares,
as the case may be; provided, however, that in the event of a Cashless Major Exercise in respect of a Non-Surviving Change of Control
Transaction, the Holder shall be deemed to have become the holder of record of the shares issuable upon such exercise immediately
prior to the consummation of such Non-Surviving Change of Control Transaction.


(c) Delivery
of Common Stock Upon Exercise. Within three (3) business days after the Date of Exercise (but, in the case of a Cash Exercise,
within two (2) business days following the Company’s receipt of the full Exercise Price, if later) or, in
the case of a Cashless Major Exercise or a Cashless Default Exercise (each as defined in Section 5(c) below), within the period
provided in Section 5(c)(iv) or Section 3(c), as applicable (the “Delivery Period”), the Company shall issue
and deliver (or cause its Transfer Agent to issue and deliver) in accordance with the terms hereof to or upon the order of the
Holder that number of shares of Common Stock (“Exercise Shares”) for the portion of this Warrant converted as shall
be determined in accordance herewith. Upon the Exercise of this Warrant or any part hereof, the Company shall, at its own cost
and expense, take all necessary action, including obtaining and delivering an opinion of counsel, to assure that the Company’s
transfer agent (the “Transfer Agent”) shall issue stock certificates in the name of Holder (or its nominee) or such
other persons as designated by Holder and in such denominations to be specified at Exercise representing the number of shares of
Common Stock issuable upon such Exercise. The Company warrants that no instructions other than these instructions have been or
will be given to the Transfer Agent and that, unless waived by the Holder, this Warrant and the Exercise Shares will be free-trading,
and freely transferable, and will not contain a legend restricting the resale or transferability of the Exercise Shares if the
Unrestricted Conditions (as defined below) are met.



    	2



    	 



    

(d) Delivery
Failure. In addition to any other remedies which may be available to the Holder, in the event that the Company fails for any
reason to effect delivery of the Exercise Shares by the end of the Delivery Period (a “Delivery Failure”), the Holder
will be entitled to revoke all or part of the relevant Exercise Form by delivery of a notice to such effect to the Company whereupon
the Company and the Holder shall each be restored to their respective positions immediately prior to the delivery of such notice,
except that the liquidated damages described herein shall be payable through the date notice of revocation or rescission is given
to the Company.


(e) Legends.


(i) Restrictive
Legend. The Holder understands that until such time as this Warrant, the Exercise Shares and the Failure Payment Shares have
been registered under the Securities Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant
to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the
number of securities as of a particular date that can then be immediately sold, this Warrant, the Exercise Shares and the Failure
Payment Shares, as applicable, may bear a restrictive legend in substantially the following form (and a stop-transfer order may
be placed against transfer of the certificates for such securities):


“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION,
PURSUANT TO RULES 144 OR 144A UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION
OR GUIDANCE, SUCH AS A SO-CALLED “4(1) AND A HALF” SALE.”


“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED
BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN REGISTRATION RIGHTS AGREEMENT DATED AS OF MAY 7, 2012,
AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY
BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.”


(ii) Removal
of Restrictive Legends. This Warrant and the certificates evidencing the Exercise Shares and the Failure Payment Shares, as
applicable, shall not contain any legend restricting the transfer thereof (including the legend set forth above in subsection 2(e)(i)):
(A) while a registration statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering
the sale or resale of such security is effective under the Securities Act, or (B) following any sale of such Warrant, Exercise
Shares and/or Failure Payment Shares pursuant to Rule 144, or (C) if such Warrant, Exercise Shares and/or Failure Payment
Shares are eligible for sale under Rule 144(b)(1), or (D) if such legend is not required under applicable requirements of
the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted
Conditions”). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective
Date if required by the Company’s transfer agent to effect the issuance of the Exercise Shares or the Failure Payment Shares,
as applicable, without a restrictive legend or removal of the legend hereunder. If the Unrestricted Conditions are met at the time
of issuance of this Warrant, the Exercise Shares or the Failure Payment Shares, then such Warrant, Exercise Shares or Failure Payment
Shares, as applicable, shall be issued free of all legends. The Company agrees that following the Effective Date at such time as
the Unrestricted Conditions are met or such legend is otherwise no longer required under this Section 2(e), it will, no later
than three (3) Trading Days following the delivery (the “Unlegended Shares Delivery Deadline”) by the Holder to the
Company or the Transfer Agent of this Warrant and a certificate representing Exercise Shares and/or Failure Payment Shares, as
applicable, issued with a restrictive legend (such third Trading Day, the “Legend Removal Date”), deliver or cause
to be delivered to such Holder a certificate (or electronic transfer) representing such shares that is free from all restrictive
and other legends. For purposes hereof, “Effective Date” shall mean the date that the
Registration Statement that the Company is required to file pursuant to the Registration Rights Agreement has been declared effective
by the SEC. 



    	3



    	 



    

(iii) Sale
of Unlegended Shares. Holder agrees that the removal of the restrictive legend from this Warrant and any certificates representing
securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that the Holder will sell this
Warrant or any Exercise Shares and/or any Failure Payment Shares, as applicable, pursuant to either the registration requirements
of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities
are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein.


(f) Cancellation
of Warrant. This Warrant shall be canceled upon the full Exercise, of this Warrant, and, as soon as practical after the Date
of Exercise, Holder shall be entitled to receive Common Stock for the number of shares purchased upon such Exercise of this Warrant,
and if this Warrant is not Exercised in full, Holder shall be entitled to receive a new Warrant (containing terms identical to
this Warrant) representing any unexercised portion of this Warrant in addition to such Common Stock.


(g) Holder
of Record. Each person in whose name any Warrant for shares of Common Stock is issued shall, for all purposes, be deemed to
be the Holder of record of such shares on the Date of Exercise of this Warrant, irrespective of the date of delivery of the Common
Stock purchased upon the Exercise of this Warrant. Prior to the exercise of this Warrant, nothing in this Warrant shall be construed
as conferring upon Holder any rights as a stockholder of the Company.


(h) Delivery
of Electronic Shares. In lieu of delivering physical certificates representing the Common Stock issuable upon Exercise or legend
removal, or representing Failure Payment Shares, provided the Transfer Agent is participating in the DTC Fast Automated Securities
Transfer (“FAST”) program, upon written request of the Holder, the Company shall use its best efforts to cause its
Transfer Agent to electronically transmit the Common Stock issuable upon Exercise to the Holder by crediting the account of the
Holder’s prime broker with DTC through its Deposit Withdrawal Agent Commission (DWAC) system. The time periods for delivery
and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic
transmission shall be effected by delivery of physical certificates.


(i) Buy-In.
In addition to any other rights available to the Holder, if the Company fails to cause its Transfer Agent to transmit to the Holder
a certificate or certificates, or electronic shares through DWAC, representing the Exercise Shares pursuant to an Exercise on or
before the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company
hereunder), and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise)
or the Holder’s brokerage firm otherwise purchases shares of Common Stock to deliver in satisfaction of a sale by the Holder
of the Exercise Shares which the Holder anticipated receiving upon such Exercise (a “Buy-In”), then the Company shall
(1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions,
if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of
Exercise Shares that the Company was required to deliver to the Holder in connection with the Exercise at issue times and (B) the
price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either
reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such Exercise was not honored or deliver
to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its Exercise
and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000
to cover a Buy-In with respect to an attempted Exercise to cover the sale of Common Stock with an aggregate sale price giving rise
to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required
to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect
of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall
limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates
representing shares of Common Stock upon Exercise of the Warrant as required pursuant to the terms hereof.

3. Payment
of Warrant Exercise Price for Cash Exercise or Cashless Exercise; Cashless Major Exercise and Cashless Default Exercise.


(a) Exercise
Price. The Exercise Price (“Exercise Price”) shall initially equal 120% of the mean of the closing share prices
of the Common Stock on NASDAQ (as defined below) as reported by Bloomberg (as defined below) over the twenty (20) consecutive Trading
Day period beginning on May 8, 2012, subject to adjustment pursuant to the terms hereof, including but not limited to Section 5
below. As soon as practicable following the foregoing twenty (20) Trading Day period, the Company shall send a notice by facsimile
to the Holder of the Company’s calculation of the Exercise Price. The Company’s calculation of the Exercise Price shall
be deemed to be final and binding upon the Holder unless, within two (2) business days of receipt of such notice, the Holder sends
a notice by facsimile ((954) 707-5360) to the Company disputing the calculation of the Exercise Price. If the Holder and the
Company are unable to agree upon the Exercise Price within two (2) business days following the receipt by the Company of the Holder’s
notice disputing the calculation of the exercise price, then the dispute shall be submitted by the Company to the Company’s
independent outside accountant and resolved in accordance with Section 3(d).


Payment of the Exercise Price may be made by either of the following,
or a combination thereof, at the election of Holder:


(i) Cash
Exercise: The Holder, at its option, may exercise this Warrant in cash, bank or cashier’s check, wire transfer or through
a reduction of an amount of principal outstanding under any Notes (as defined in the Facility Agreement) in accordance with Section
2.3 of the Facility Agreement, then held by the Holder (a “Cash Exercise”); or


(ii) Cashless
Exercise: The Holder may exercise this Warrant in a cashless exercise transaction. In order to effect a Cashless Exercise,
the Holder shall surrender this Warrant at the principal office of the Company together with notice of cashless election, in which
event the Company shall issue Holder a number of shares of Common Stock computed using the following formula (a “Cashless
Exercise”):


X = Y (A-B)/A


	where:	X = the number of shares of Common Stock to be issued to Holder.



Y = the number of shares of Common Stock for which this Warrant
is being Exercised.


A = the Market Price of one (1) share of Common Stock (for
purposes of this Section 3(a)(ii), where “Market Price,” as of any date, means the Volume Weighted Average Price
(as defined herein) of the Company’s Common Stock for the ten (10) consecutive Trading Day period immediately preceding the
date in question.


B = the Exercise Price.


As used herein, “Volume Weighted Average Price”
for any security as of any date means the volume weighted average sale price on The NASDAQ Global Select Market (“NASDAQ”)
as reported by, or based upon data reported by Bloomberg Financial Markets or an equivalent, reliable reporting service mutually
acceptable to and hereinafter designated by holders of a majority in interest of the Warrants and the Company (“Bloomberg”)
or, if NASDAQ is not the principal trading market for such security, the volume weighted average sale price of such security on
the principal securities exchange or trading market where such security is listed or traded as reported by Bloomberg or, if no
volume weighted average sale price is reported for such security by Bloomberg, then the last closing trade price of such security
as reported by Bloomberg, or, if no last closing trade price is reported for such security by Bloomberg, the average of the bid
prices of any market makers for such security that are listed in the over the counter market by the Financial Industry Regulatory
Authority, Inc. or on the “over the counter” Bulletin Board (or any successor) or in the “pink sheets”
(or any successor) by the OTC Markets Group, Inc. If the Volume Weighted Average Price cannot be calculated for such security on
such date in the manner provided above, the Volume Weighted Average Price shall be the fair market value as mutually determined
by the Company and the Holders of a majority in interest of the Warrants being Exercised for which the calculation of the Volume
Weighted Average Price is required in order to determine the Exercise Price of such Warrants. “Trading
Day” shall mean any day on which the Common Stock is traded for any period on NASDAQ, or on the principal securities exchange
or other securities market on which the Common Stock is then being traded. 



    	5



    	 



    

For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended, understood and acknowledged that the Common Stock issuable upon Exercise of this Warrant in a Cashless Exercise transaction
shall be deemed to have been acquired at the time this Warrant was issued. Moreover, it is intended, understood and acknowledged
that the holding period for the Common Stock issuable upon Exercise of this Warrant in a Cashless Exercise transaction shall be
deemed to have commenced on the date this Warrant was issued.


(b)
Cashless Major Exercise. To the extent the Holder shall exercise this Warrant or any portion thereof as a Cashless Major
Exercise pursuant to Section 5(c)(i) below, the Holder shall surrender this Warrant at the principal office of the Company together
with the Exercise Form indicating that the Holder is exercising this Warrant (or such portion thereof) pursuant to a Cashless Major
Exercise, in which event the Company shall issue a number of shares of Common Stock equal to the Black-Scholes Value (as defined
in Section 5(c)(iii) below) of the Warrant (or such applicable portion being exercised) divided by the closing price of the Common
Stock on the principal securities exchange or other securities market on which the Common Stock is then traded on the Trading Day
immediately preceding the date on which the applicable Major Transaction is consummated.


(c)
Cashless Default Exercise. To the extent the Holder exercises this Warrant as a Cashless Default Exercise pursuant to Section
11(b)(i) below, the Holder shall surrender this Warrant to the principal office of the Company together with the Exercise Form
indicating that the Holder is exercising this Warrant pursuant to a Cashless Default Exercise, in which event the Company shall,
at the election of the Company, (i) issue to the Holder, within five (5) Trading Days of the applicable Default Notice, a number
of shares of Common Stock (which shares shall be valued at the Volume Weighted Average Price for the five (5) Trading Days prior
to the applicable Default Notice) equal to the Black-Scholes value (determined by use of the Black-Scholes Option Pricing Model
using the criteria set forth on Schedule I hereto) of the remaining unexercised portion of this Warrant on the date of such Default
Notice (the “Cashless Default Exercise Amount”), or (ii) pay the Cashless Default Exercise Amount to the Holder in
cash.


(d) Dispute
Resolution. Subject to the provisions of Section 3(a), in the case of a dispute as to the determination of the closing price
or Volume Weighted Average Price of the Company’s Common Stock or the arithmetic calculation of the Exercise Price, Market
Price or any Major Transaction Warrant Early Termination Price, the Company shall submit the disputed determinations or arithmetic
calculations via facsimile within two (2) business days of receipt, or deemed receipt, of the Exercise Notice or Major Transaction
Early Termination Notice, or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder and the
Company are unable to agree upon such determination or calculation within two (2) business days of such disputed determination
or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) business days submit via facsimile
(i) the disputed determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock
to an independent, reputable investment bank selected by the Company and approved by the Holder, which approval shall not be unreasonably
withheld or (ii) the disputed arithmetic calculation of the Exercise Price, Market Price or any Major Transaction Warrant
Early Termination Price to the Company’s independent, outside accountant. The Company shall use reasonable commercial efforts
to cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the
Company and the Holder of the results no later than five (5) business days from the time it receives the disputed determinations
or calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be
binding upon all parties absent demonstrable error, and the Company and the Holder shall each pay one half of the fees and costs
of such investment banker or accountant.


4. Transfer
and Registration.


(a) Transfer
Rights. Subject to the provisions of Section 8 of this Warrant, this Warrant may be transferred on the books of the Company,
in whole or in part, in person or by attorney, upon surrender of this Warrant properly completed and endorsed. This Warrant shall
be canceled upon such surrender and, as soon as practicable thereafter, the person to whom such transfer is made shall be entitled
to receive a new Warrant or Warrants as to the portion of this Warrant transferred, and Holder shall be entitled to receive a new
Warrant as to the portion hereof retained.



    	6



    	 



    

(b) Registrable
Securities. The Common Stock issuable upon the Exercise of this Warrant has registration rights pursuant to the Registration
Rights Agreement.


5. Adjustments
Upon Certain Events.


(a) Participation.
The Holder, as the holder of this Warrant, shall be entitled to receive such dividends paid and distributions of any kind made
to the holders of Common Stock of the Company to the same extent as if the Holder had Exercised this Warrant into Common Stock
(without regard to any limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of
shares are authorized and reserved to effect any such exercise and issuance) and had held such shares of Common Stock on the record
date for such dividends and distributions. Payments under the preceding sentence shall be made concurrently with the dividend or
distribution to the holders of Common Stock.


(b) Recapitalization
or Reclassification. If the Company shall at any time effect a stock split, payment of stock dividend, recapitalization, reclassification
or other similar transaction of such character that the shares of Common Stock shall be changed into or become exchangeable for
a larger or smaller number of shares, then upon the effective date thereof, the number of shares of Common Stock which Holder shall
be entitled to purchase upon Exercise of this Warrant shall be increased or decreased, as the case may be, in direct proportion
to the increase or decrease in the number of shares of Common Stock by reason of such stock split, payment of stock dividend, recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the case of an increase in the number of shares, proportionally
decreased and, in the case of decrease in the number of shares, proportionally increased. The Company shall give Holder the same
notice it provides to holders of Common Stock of any transaction described in this Section 5(b).


(c) Rights
Upon Major Transaction.


(i) Major Transaction. In the event
that a Major Transaction (as defined below) occurs, then
(1) in the case of a Major Transaction covered by the provisions of Section 5(c)(i)(A) below in which the Company is not the surviving
entity and in which the consideration consists solely of securities of a Publicly Traded Successor Entity, as defined below (a
“Qualified Change of Control Transaction”), the Company shall have the right to treat such Major Transaction as an
Assumption, (2) in the case of a Cash-Out Major Transaction, and in the case of a Mixed Major Transaction to the extent of the
percentage of the cash consideration in the Mixed Major Transaction (determined in accordance with the definition of a Mixed Major
Transaction below), the Holder, at its option, may require the Company to redeem the Holder’s outstanding Warrants
in accordance with Section 5(c)(iii) below and
(3) in the case of all other Major Transactions (including, without limitation, a Qualified Change of Control Transaction for which
the Company does not make an Assumption Election (as defined below)), and in the case of a Mixed Major Transaction to the extent
of the percentage of the consideration represented by securities of a Successor Entity in the Mixed Major Transaction, the Holder
shall have the right to exercise this Warrant as a Cashless Major Exercise. In the event the Holder shall not have exercised any
of its rights under clauses (2) or (3) above within the applicable time periods set forth herein, then the Major Transaction shall
be treated as an Assumption (as defined below) in accordance with Section 5(c)(ii) below. Notwithstanding anything herein to the
contrary, the Holder may waive its rights under this Section 5(c) with respect to any Major Transaction in which event
none of the provisions of this Section 5(c) shall apply with respect to such Major Transaction. In the event of a Major Transaction
in which all shares of Common Stock are cancelled and converted into the right to receive cash and/or securities of Another Entity
(as defined below), then, any portion of this Warrant that is neither redeemed, assumed or exercised pursuant to the terms of this
Warrant prior to the closing of such Major Transaction, shall automatically and immediately convert into shares of Common Stock,
and shall be deemed to have been exercised pursuant to a Cashless Exercise, immediately prior to the consummation of such Major
Transaction. Each of the following events shall constitute a “Major Transaction”.


(A) a
consolidation, merger, exchange of shares, recapitalization, reorganization, business combination or other similar event, (1) following
which the holders of Common Stock immediately preceding such consolidation, merger, exchange, recapitalization, reorganization,
combination or event either (a) no longer hold a majority of the shares of Common Stock or (b) no longer have the ability
to elect a majority of the board of directors of the Company or (2) as a result of which shares of Common Stock shall be changed
into (or the shares of Common Stock become entitled to receive) a different class or classes of stock or securities of the Company
or another entity (collectively, a “Change of Control Transaction”);



    	7



    	 



    

(B) the
sale or transfer in one transaction or a series of related transactions of (i) all or substantially all of the assets of the Company,
or (ii) assets of the Company for a purchase price equal to more than 50% of the Enterprise Value (as defined below) of the Company.
For purposes of this clause (B), “Enterprise Value” shall mean (I) the product of (x) the number of issued and outstanding
shares of Common Stock on the date the Company delivers the Major Transaction Notice (defined below) multiplied by (y) the per
share closing price of the Common Stock on such date plus (II) the amount of the Company’s debt as shown on the latest financial
statements filed with the SEC (the “Current Financial Statements”) less (III) the amount of cash and cash equivalents
of the Company as shown on the Current Financial Statements;


(C) a
purchase, tender or exchange offer made to the holders of outstanding shares of Common Stock, such that following such purchase,
tender or exchange offer a Change of Control Transaction shall have occurred; or


(D) the
liquidation, bankruptcy, insolvency, dissolution or winding-up (or the occurrence of any analogous proceeding) of the Company.


(ii) Assumption.
The Company shall not enter into or be party to a Major Transaction that is to be treated as an Assumption pursuant to Section
5(c)(i), unless (A) the successor entity resulting from such Major Transaction (in each case, a “Successor Entity”),
assumes in writing all of the obligations of the Company under this Warrant, the Facility Agreement (but only if there will be
an outstanding balance under the Facility Agreement immediately following the closing of the Major Transaction) and the Registration
Rights Agreement  in accordance with the provisions of this Section (ii) pursuant to written agreements in form and substance
reasonably satisfactory to the Holder and approved by the Holder prior to such Major Transaction (not to be unreasonably withheld
or delayed), including agreements to deliver to each holder of Warrants in exchange for such Warrants a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to the Warrants, including, without limitation,
representing the appropriate number of shares of the Successor Entity, having similar exercise rights as the Warrants (including
but not limited to a similar Exercise Price and similar Exercise Price adjustment provisions based on the price per share or conversion
ratio to be received by the holders of Common Stock in the Major Transaction) and similar registration rights as provided by the
Registration Rights Agreement, reasonably satisfactory to the Holder and (B) the Successor Entity is a Public Successor Entity.
Upon the occurrence of any Major Transaction, any Successor Entity shall succeed to, and be substituted for (so that from and after
the date of such Major Transaction, the provisions of this Warrant and the Registration Rights Agreement referring to the “Company”
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.
Upon consummation of the Major Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued
upon exercise or redemption of this Warrant at any time after the consummation of the Major Transaction, in lieu of the shares
of Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the Warrants prior to such
Major Transaction, such shares of publicly traded common stock (or their equivalent) of the Successor Entity, as adjusted in accordance
with the provisions of this Warrant. The provisions of this Section shall apply similarly and equally to successive Major Transactions
and shall be applied without regard to any limitations on the exercise of this Warrant other than any applicable beneficial ownership
limitations. Any assumption of Company obligations under this paragraph shall be referred to herein as an “Assumption”


(iii) Notice;
Major Transaction Early Termination Right; Notice of Cashless Major Exercise. At least thirty (30) days prior to the consummation
of any Major Transaction, but, in any event, within five (5) Business Days following the first to occur of (x) the date of
the public announcement of such Major Transaction if such announcement is made before 4:00 p.m., New York City time, or (y) the
day following the public announcement of such Major Transaction if such announcement is made on and after 4:00 p.m., New York City
time, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Major Transaction
Notice”). The Major Transaction Notice with respect to a Qualified Change of Control Transaction shall also state whether
the Company is electing to treat such Major Transaction as an Assumption (an “Assumption Election”). At any time during
the period beginning after the Holder’s receipt of a Major Transaction Notice and ending five (5) Trading Days prior to the
consummation of such Major Transaction (the “Early Termination Period”), the Holder may require the Company to redeem
(an “Early Termination Upon Major Transaction”) all or any portion of this Warrant not treated as an Assumption and
not eligible to be treated as a Cashless Major Exercise (without taking into consideration the 9.985% Cap) by delivering written
notice thereof (“Major Transaction Early Termination Notice”) to the Company, which Major Transaction Early Termination
Notice shall indicate the portion of this Warrant, measured by the number of Shares then subject to this Warrant (the “Early
Termination Principal Amount”) of the Warrant that the Holder is electing to have redeemed. The portion of this Warrant subject
to early termination pursuant to this Section 5(c)(iii) (the “Redeemable Shares”), shall be redeemed by the Company
at a price (the “Major Transaction Warrant Early Termination Price”) payable in cash equal to the “Black Scholes
Value” of the Redeemable Shares determined by use of the Black Scholes Option Pricing Model using the criteria set forth
in Schedule 1 hereto (the “Black Scholes Value”). In the event the Major Transaction Notice relating to a Qualified
Change of Control Transaction includes an Assumption Election, the Holder shall send written notice to the Company within the Early
Termination Period if the Holder elects to waive this Section 5(c) in its entirety in which event no Assumption shall occur.



    	8



    	 



    

To
the extent the Holder shall elect to effect a Cashless Major Exercise in respect of a Major Transaction, the Holder shall deliver
its exercise notice in accordance with Section 3(b), within the Early Termination Period.


(iv) Escrow;
Payment of Major Transaction Warrant Early Termination Price. Following the receipt of a Major Transaction Early Termination
Notice or a Cashless Major Exercise from the Holder, the Company shall not effect a Major Transaction that is being treated as
an early termination or is eligible to be treated as a Cashless Major Exercise unless either (a) it obtains the written agreement
of the Successor Entity that payment of the Major Transaction Warrant Early Termination Price and/or issuance of the applicable
Exercise Shares shall be made to the Holder prior to consummation of such Major Transaction and such issuance or payment shall
be a condition precedent to consummation of such Major Transaction or (b) it shall first place into an escrow account with an independent
escrow agent, at least three (3) business days prior to the closing date of the Major Transaction (the “Major Transaction
Escrow Deadline”), an amount in shares of Common Stock or cash, as applicable, equal to the Major Transaction Warrant Early
Termination Price and/or applicable Exercise Shares. Concurrently upon closing of such Major Transaction, the Company shall pay
or shall instruct the escrow agent to pay the Major Transaction Warrant Early Termination Price and/or to deliver the applicable
Exercise Shares to the Holder. For purposes of determining the amount required to be placed in escrow pursuant to the provisions
of this subsection (iv) and without affecting the amount of the actual Major Transaction Warrant Early Termination Price and/or
applicable Exercise Shares, the calculation of the price referred to in clause (1) of the first column of Schedule 1 hereto
with respect to Stock Price shall be determined based on the Closing Market Price (as defined on Schedule I) of the Common Stock
on the Trading Day immediately preceding the date that the funds and/or applicable Exercise Shares, as applicable, are deposited
with the escrow agent.


(v) Injunction.
Following the receipt of a Major Transaction Early Termination Notice or notice of a Cashless Major Exercise from the Holder, in
the event that the Company attempts to consummate a Major Transaction without either (1) placing the Major Transaction Warrant
Early Termination Price or applicable Exercise Shares, as applicable, in escrow in accordance with subsection (iv) above, (2) payment
of the Major Transaction Warrant Early Termination Price or issuance of the applicable Exercise Shares, as applicable, to the Holder
prior to consummation of such Major Transaction or (3) obtaining the written agreement of the Successor Entity described in subsection
(iv) above, the Holder shall have the right to apply for an injunction in any state or federal courts sitting in the City of New
York, borough of Manhattan to prevent the closing of such Major Transaction until the Major Transaction Warrant Early Termination
Price is paid to the Holder, in full or the applicable Exercise Shares are delivered or deposited in escrow, as applicable.


An early termination required by this Section 5(c) shall be
made in accordance with the provisions of Section 12 and shall have priority to payments to holders of Common Stock in connection
with a Major Transaction , and to the extent an early termination required by this Section 5(c)(iii) are deemed or determined
by a court of competent jurisdiction to be prepayments of the Warrant by the Company, such early termination shall be deemed to
be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, until the Major Transaction Warrant Early
Termination Price is paid in full, this Warrant may be exercised, in whole or in part, by the Holder into shares of Common Stock,
or in the event the Exercise Date is after the consummation of the Major Transaction, shares of publicly traded common stock (or
their equivalent) of the Successor Entity pursuant to Section 5(c). The parties hereto agree that in the event of the early termination
of any portion of the Warrant under this Section 5(c), the Holder’s damages would be uncertain and difficult to estimate
because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable
substitute investment opportunity for the Holder. Accordingly, any premium due under this Section 5(c) is intended by the
parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not
as a penalty.



    	9



    	 



    

For purposes hereof:


“Another Entity” shall mean an entity in which the holders
of a majority of the shares of Common Stock of the Company immediately prior to the consummation of a Major Transaction do not
hold a majority of the equity securities in such entity.


“Cash-Out Major Transaction” means a Major Transaction
in which the consideration payable to holders of Common Stock in connection with the Major Transaction consists solely of cash.


“Cashless

of the Publicly Traded Successor Entity to be issued to holders of Common Stock of the Company represents in comparison to the
aggregate value of all consideration, including cash consideration, in such Mixed Major Transaction, as such values are set forth
in any definitive agreement for the Mixed Major Transaction that has been executed at the time of the first public announcement
of the Major Transaction or, if no such value is determinable from such definitive agreement, based on the closing market price
for shares of the Publicly Traded Successor Entity on its principal securities exchange on the Trading Day preceding the first

represented by securities of such Successor Entity shall be determined in good-faith by the Company's Board of Directors

(d) Exercise
Price Adjusted. As used in this Warrant, the term “Exercise Price” shall mean the purchase price per share specified
in Section 3(a) of this Warrant, until the occurrence of an event stated in this Section 5 or otherwise set forth in
this Warrant, and thereafter shall mean said price as adjusted from time to time in accordance with the provisions of said subsection.
No adjustment made pursuant to any provision of this Section 5 shall have the net effect of increasing the Exercise Price
in relation to the split adjusted and distribution adjusted price of the Common Stock.


(e) Adjustments:
Additional Shares, Securities or Assets. In the event that at any time, as a result of an adjustment made pursuant to this
Section 5 or otherwise, Holder shall, upon Exercise of this Warrant, become entitled to receive shares and/or other securities
or assets (other than Common Stock) then, wherever appropriate, all references herein to shares of Common Stock shall be deemed
to refer to and include such shares and/or other securities or assets; and thereafter the number of such shares and/or other securities
or assets shall be subject to adjustment from time to time in a manner and upon terms as nearly equivalent as practicable to the
provisions of this Section 5.


(f) Notice
of Adjustments. Whenever the Exercise Price is adjusted pursuant to the terms of this Warrant, the Company shall promptly mail
to the Holder a notice (an “Exercise Price Adjustment Notice”) setting forth the Exercise Price after such adjustment
and setting forth a statement of the facts requiring such adjustment. The Company shall, upon the written request at any time of
the Holder, furnish to such Holder a like Warrant setting forth (i) such adjustment or readjustment, (ii) the Exercise
Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or
property which at the time would be received upon Exercise of the Warrant. For purposes of clarification, whether or not the Company
provides an Exercise Price Adjustment Notice pursuant to this Section 5(f), upon the occurrence of any event that leads to
an adjustment of the Exercise Price, the Holder would be entitled to receive a number of Exercise Shares based upon the new Exercise
Price, as adjusted, for exercises occurring on or after the date of such adjustment, regardless of whether the Holder accurately
refers to the adjusted Exercise Price in the Exercise Form.


6. Fractional
Interests.


No fractional shares or scrip representing fractional shares shall
be issuable upon the Exercise of this Warrant, but on Exercise of this Warrant, Holder may purchase only a whole number of shares
of Common Stock. If, on Exercise of this Warrant, Holder would be entitled to a fractional share of Common Stock or a right to
acquire a fractional share of Common Stock, such fractional share shall be disregarded and the number of shares of Common Stock
issuable upon Exercise shall be the next higher whole number of shares.


7. Reservation
of Shares.


From and after the date hereof, the Company shall at all times reserve
for issuance such number of authorized and unissued shares of Common Stock (or other securities substituted therefor as herein
above provided) as shall be sufficient for the Exercise of this Warrant and payment of the Exercise Price. If at any time the number
of shares of Common Stock authorized and reserved for issuance is below the number of shares sufficient for the Exercise of this
Warrant (a “Share Authorization Failure”) (based on the Exercise Price in effect from time to time), the Company will
promptly take all corporate action necessary to authorize and reserve a sufficient number of shares, including, without limitation,
calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations under this Section 7,
in the case of an insufficient number of authorized shares, and using its best efforts to obtain stockholder approval of an increase
in such authorized number of shares. The Company covenants and agrees that upon the Exercise of this Warrant, all shares of Common
Stock issuable upon such Exercise shall be duly and validly issued, fully paid and nonassessable and not subject to preemptive
rights, rights of first refusal or similar rights of any Person.


8. Restrictions
on Transfer.


(a) Registration
or Exemption Required. This Warrant has been issued in a transaction exempt from the registration requirements of the Securities
Act by virtue of Regulation D and exempt from state registration or qualification under applicable state laws. None of the Warrant,
the Exercise Shares or Failure Payment Shares may be pledged, transferred, sold or assigned except pursuant to an effective registration
statement or an exemption to the registration requirements of the Securities Act and applicable state laws including, without limitation,
a so-called “4(1) and a half” transaction.



    	11



    	 



    

(b) Assignment.
Subject to Section 8(a), the Holder may sell, transfer, assign, pledge, or otherwise dispose of this Warrant, in whole or
in part. Holder shall deliver a written notice to Company, substantially in the form of the Assignment attached hereto as Exhibit B,
indicating the Person or Persons to whom the Warrant shall be assigned and the respective number of warrants to be assigned to
each assignee. The Company shall effect the assignment within three (3) business days (the “Transfer Delivery Period”),
and shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of like tenor and terms for the appropriate number
of shares. This Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns
of the Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant,
and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or
transfer is a so called “4(1) and half” transaction, the parties hereto agree that a legal opinion from outside counsel
for the Holder delivered to counsel for the Company substantially in the form attached hereto as Exhibit C shall be
the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4(1) and half”
transaction.


9. Noncircumvention.


The Company hereby covenants and agrees that the Company will not,
by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger,
scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant
and take all action as may be reasonably required to protect the rights of the Holder. Without limiting the generality of the foregoing,
the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant
above the Exercise Price then in effect, and (ii) shall take all such actions as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant.


10. Events
of Failure; Definition of Black Scholes Value.


(a) Definition. 


The occurrence of each of the following shall be considered to be
an “Event of Failure.”


(i) A Delivery Failure occurs, where a “Delivery Failure”
shall be deemed to have occurred if the Company fails to use its best efforts to deliver Exercise Shares to the Holder within any
applicable Delivery Period (other than due to the limitation contained in the proviso in the second paragraph of Section 1);


(ii) A Legend Removal Failure occurs, where a “Legend
Removal Failure” shall be deemed to have occurred if the Company fails to use its best efforts to issue this Warrant and/or
Exercise Shares without a restrictive legend, or fails to use it best efforts to remove a restrictive legend, when and as required
under Section 2(e) hereof;


(iii) a Transfer Delivery Failure occurs, where a “Transfer
Delivery Failure” shall be deemed to have occurred if the Company fails to use its best efforts to deliver a Warrant within
any applicable Transfer Delivery Period; and


(iv) a Registration Failure (as defined below).



    	12



    	 



    

For purpose hereof, “Registration Failure” means that
(A) the Company fails to file with the SEC on or before the Filing Deadline (as defined in the Registration Rights Agreement)
any Registration Statement required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, (B) the
Company fails to use its reasonable commercial efforts to obtain effectiveness with the SEC, prior to the Registration Deadline
(as defined in the Registration Rights Agreement), and if such Registration Statement is not so filed prior to the Registration
Deadline, as soon as possible thereafter, of any Registration Statement (as defined in the Registration Rights Agreement) that
are required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, or fails to use reasonable commercial
efforts to keep such Registration Statement current and effective as required in Section 3 of the Registration Rights Agreement,
(C) The Company fails to file any additional Registration Statements required to be filed pursuant to Section 2(a)(ii) of the Registration
Rights Agreement on or before the Additional Filing Deadline or fails to use its reasonable commercial efforts to cause such new
Registration Statement to become effective on or before the Additional Registration Deadline, and if such effectiveness does not
occur within such period, as soon as possible thereafter, (D) the Company fails to file any amendment to any Registration
Statement, or any additional Registration Statement required to be filed pursuant to Section 3(b) of the Registration Rights
Agreement within twenty (20) days of the applicable Registration Trigger Date (as defined in the Registration Rights Agreement),
or fails to use its reasonable commercial efforts to cause such amendment and/or new Registration Statement to become effective
within sixty (60) days of the applicable Registration Trigger Date, and, if such effectiveness does not occur within such
period, as soon as possible thereafter, (E) any Registration Statement required to be filed under the Registration Rights
Agreement, after its initial effectiveness and during the Registration Period (as defined in the Registration Rights Agreement),
lapses in effect or sales of all of the Registrable Securities (as defined in the Registration Rights Agreement) cannot otherwise
be made thereunder (whether by reason of the Company’s failure to amend or supplement the prospectus included therein in
accordance with the Registration Rights Agreement, the Company’s failure to file and, use reasonable commercial efforts to
obtain effectiveness with the SEC of an additional Registration Statement or amended Registration Statement required pursuant to
Sections 2(a)(ii) or 3(b) of the Registration Rights Agreement, as applicable, or otherwise), and (F) the Company fails to
provide a commercially reasonable written response to any comments to any Registration Statement submitted by the SEC within twenty
(20) days of the date that such SEC comments are received by the Company.


(b) Failure Payments; Black-Scholes Determination. The Company
understands that any Event of Failure (as defined above) could result in economic loss to the Holder. In the event that any Event
of Failure occurs, as compensation to the Holder for such loss, the Company agrees to pay (as liquidated damages and not as a penalty)
to the Holder an amount (“Failure Payments”) payable, at the Company’s option, either (i) in cash or (ii) in
shares of Common Stock that are valued for these purposes at the Volume Weighted Average Price on the date of such calculation
(“Failure Payment Shares”), in each case equal to 15% per annum (or the maximum rate permitted by applicable law,
whichever is less) of the Black-Scholes value (as determined below) of the remaining unexercised portion of this Warrant on the
date of such Event of Failure (as recalculated on the first business day of each month thereafter for as long as Failure Payments
shall continue to accrue), which shall accrue daily from the date of such Event of Failure until the Event of Failure is cured,
accruing daily and compounded monthly, provided, however, the Holder shall only receive up to such amount of shares of Common Stock
in respect of Failure Payments such that Holder and any other persons or entities whose beneficial ownership of Common Stock would
be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group”
of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to
acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein)
shall not collectively beneficially own greater than 9.985% of the total number of shares of Common Stock of the Company then issued
and outstanding. For purposes of clarification, it is agreed and understood that Failure Payments shall continue to accrue following
any Event of Default until the applicable Default Amount is paid in full.


Notwithstanding the above, (1) in the event that the Company (i) has,
by the Filing Deadline (as defined the Registration Rights Agreement) filed a Registration Statement (as defined in the Registration
Rights Agreement) covering the number of shares required by the Registration Rights Agreement, and (ii) has responded in writing
to any comments to the Registration Statement that the Company has received from the SEC, within seven (7) Business Days of
such receipt, and nevertheless the SEC has not declared effective a Registration Statement covering the full number of Warrant
Shares issuable upon exercise of the Warrants by the Registration Deadline (as defined in the Registration Rights Agreement) then,
the Failure Payments attributable to such late Registration Effectiveness shall be reduced from 15% per annum to 12% (calculated
as set forth above) and (2) in no event shall the aggregate Failure Payments attributable solely to the failure by the SEC to declare
a Registration Statement effective exceed 10% of the Black-Scholes value of the Warrant. The Company shall satisfy any Failure
Payments under this Section pursuant to Section 10(c) below. Failure Payments are in addition to any Shares that the Holder is
entitled to receive upon Exercise of this Warrant.


For purposes hereof, the “Black-Scholes” value of a Warrant
shall be determined by use of the Black Scholes Option Pricing Model using the criteria set forth on Schedule 1 hereto.



    	13



    	 



    

(c) Payment of Accrued Failure Payments. The Failure Payment
Shares representing accrued Failure Payments for each Event of Failure shall be issued and delivered on or before the fifth (5th) business
day of each month following a month in which Failure Payments accrued and shall be the sole measure of damages for the Event of
Failure to which the Failure Payments relate. Nothing herein shall limit the Holder’s right to pursue a claim for specific
performance and/or injunctive relief. Notwithstanding the above, if a particular Event of Failure results in an Event of Default
pursuant to Section 11 hereof, then the Failure Payment, for that Event of Failure only, shall be considered to have been
satisfied upon payment to the Holder of an amount equal to the greater of (i) the Failure Payment, or (ii) the Default
Amount, payable in accordance with Section 11.


(d) Maximum Interest Rate. Nothing contained herein or in any
document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of
interest or other charges in excess of the maximum permitted by applicable law. In the event that the rate of interest or dividends
required to be paid or other charges hereunder exceed the maximum permitted by such law, any payments in excess of such maximum
shall be credited against amounts owed by the Company to the Holder and thus refunded to the Company.


 


11. Default.


(a) Events Of Default. Each of the following events shall
be considered to be an “Event of Default,” unless waived by the Holder:


(i) Failure
To Effect Registration. With respect to all Registration Failures, a Registration Failure occurs and remains uncured for a
period of more than forty-five (45) days (or sixty (60) days in the case where the Company (i) has, by the Filing Deadline
(as defined the Registration Rights Agreement) filed a Registration Statement (as defined in the Registration Rights Agreement)
covering the number of shares required by the Registration Rights Agreement, and (ii) has responded in writing to any comments
to the Registration Statement that the Company has received from the SEC, within seven (7) Business Days of such receipt,
and nevertheless the SEC has not declared effective a Registration Statement covering the Shares by the Registration Deadline (as
defined in the Registration Rights Agreement)), and such Registration Failure relates solely to the Company’s failure
to have the Registration Statement declared effective by the Registration Deadline (as defined in the Registration Rights Agreement)
and with respect to a Registration Failure provided in clause (E) of the definition of “Registration Failure”, such
Registration Failure occurs and remains uncured for a period of more than forty-five (45) days.


(ii) Failure
To Deliver Common Stock. A Delivery Failure (as defined above) occurs and remains uncured for a period of more than twenty
(20) days; or at any time, the Company announces or states in writing that it will not honor its obligations to issue shares of
Common Stock to the Holder upon Exercise by the Holder of the Exercise rights of the Holder in accordance with the terms of this
Warrant.


(iii) Legend
Removal Failure. A Legend Removal Failure (as defined above) occurs and remains uncured for a period of twenty (20) days; and


(iv) Corporate
Existence; Major Transaction. (A) The Company has failed to either (1) place the Major Transaction Warrant Early Termination
Price or the Exercise Shares issuable upon exercise of a Cashless Major Exercise, as the case may be, into escrow or (2) obtain
the written agreement of the Successor Entity as described in Section 5(c)(iv), or the Company has failed to instruct the escrow
agent to release such amount or such shares, as the case may be, to the Holder pursuant to Section 5(c)(iv), or
(B) with respect to a Major Transaction that is to be treated as an Assumption under the terms hereof, the Company has failed to
meet the Assumption requirements of Section 5(c)(ii).


(b) Mandatory
Early Termination.


(i) Mandatory
Early Termination Amount; Cashless Default Exercise. If any Events of Default shall occur then, unless waived by the Holder,
upon the occurrence and during the continuation of any Event of Default, at the option of the Holder, such option exercisable through
the delivery of written notice to the Company by such Holder (the “Default Notice”), the Company shall have the right
to terminate the outstanding amount of this Warrant and pay to the Holder (a “Mandatory Early Termination”), in full
satisfaction of its obligations hereunder by delivery of a notice to such effect to the Holder within two (2) Business Days following
receipt of the Default Notice, an amount payable in cash (the “Mandatory Early Termination Amount” or the “Default
Amount”) equal to the Black-Scholes value (as determined in accordance with Section 10(b)) of the remaining unexercised
portion of this Warrant on the date of such Default Notice. In
the event the Company does not exercise its right to consummate a Mandatory Early Termination, then the Holder shall have the right
to exercise this Warrant pursuant to a Cashless Default Exercise in accordance with Section 3(c) above.



    	14



    	 



    

The Mandatory Early Termination Amount shall be payable within five
(5) Business Days following the date of the applicable Default Notice.


(ii) Liquidated
Damages. The parties hereto acknowledge and agree that the sums payable as Failure Payments or pursuant to a Mandatory Early
Termination shall give rise to liquidated damages and not penalties. The parties further acknowledge that (i) the amount of
loss or damages likely to be incurred by the Holder is incapable or is difficult to precisely estimate, (ii) the amounts specified
bear a reasonable proportion and are not plainly or grossly disproportionate to the probable loss likely to be incurred by the
Holder, and (iii) the parties are sophisticated business parties and have been represented by sophisticated and able legal
and financial counsel and negotiated this Agreement at arm’s length.


(c) Posting
Of Bond. In the event that any Event of Default occurs hereunder, the Company may not raise as a legal defense (in any Lawsuit,
as defined below, or otherwise) or justification to such Event of Default any claim that such Holder or any one associated or affiliated
with such Holder has been engaged in any violation of law, unless the Company has posted a surety bond (a “Surety Bond”)
for the benefit of such Holder in the amount of 130% of the aggregate Surety Bond Value (as defined below) of all of the Holder’s
Warrants (the “Bond Amount”), which Surety Bond shall remain in effect until the completion of litigation of the dispute
and the proceeds of which shall be payable to such Holder to the extent Holder obtains judgment.


For purposes hereof, a “Lawsuit” shall
mean any lawsuit, arbitration or other dispute resolution filed by either party herein pertaining to any of this Warrant, the Facility
Agreement and the Registration Rights Agreement.


“Surety Bond Value,” for the Warrants
shall mean 130% of the of the Black-Scholes value of the remaining unexercised portion of this Warrant on the Trading Day immediately
preceding the date that such bond goes into effect).


(d) Remedies,
Other Obligations, Breaches And Injunctive Relief. The remedies provided in this Warrant shall be cumulative and in addition
to all other remedies available under this Warrant, the Facility Agreement and the Registration Rights Agreement, at law or in
equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of
the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such
breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of
this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being required.


12. Holder’s
Early Terminations.


(a) Mechanics
of Holder’s Early Terminations. In the event that the Company does not deliver the applicable Major Transaction Warrant
Early Termination Price or Default Amount or the Exercise Shares in respect of a Cashless Major Exercise or a Cashless Default
Exercise, as the case may be, to the Holder within ten (10) days following the time period or as otherwise required pursuant to
the terms hereof, at any time thereafter the Holder shall have the option, upon notice to the Company, in lieu of early termination,
Cashless Major Exercise or Cashless Default Exercise, as the case may be, to require the Company to promptly return to the Holder
all or any portion of this Warrant that was submitted for early termination or exercise. Upon the Company’s receipt of such
notice, (x) the applicable early termination or exercise, as the case may be, shall be null and void with respect to such
applicable portion of this Warrant, (y) the Company shall immediately return this Warrant, or issue a new Warrant to the Holder
representing the portion of this Warrant that was submitted for early termination or exercise and (z) the Exercise Price of
this Warrant or such new Warrant shall be adjusted to the lesser of (A) the Exercise Price as in effect on the date on which the
applicable early termination, default or exercise notice, as the case may be, is voided and (B) the lowest closing price for the
Common Stock on NASDAQ, or, if NASDAQ is not the principal trading market for the Common Stock, the principal securities exchange
or other securities market on which the Common Stock is then being traded, during the period beginning on and including the date
on which the applicable early termination or exercise notice, as the case may be, is delivered to the Company and ending on and
including the date on which the applicable early termination or exercise is voided. The Holder’s delivery of a notice voiding
an early termination or exercise and exercise of its rights following such notice shall not affect the Company’s obligations
to make any payments of Failure Payments which have accrued prior to the date of such notice with respect to the Warrant subject
to such notice.



    	15



    	 



    

13. Benefits
of this Warrant.


Nothing in this Warrant shall be construed to confer upon any person
other than the Company and Holder any legal or equitable right, remedy or claim under this Warrant and this Warrant shall be for
the sole and exclusive benefit of the Company and Holder.


14. Governing
Law.


All questions concerning the construction, validity, enforcement
and interpretation of this Agreement shall be governed by and construed and enforced in accordance with the internal laws of the
State of New York, without regard to the principles of conflicts of law thereof. Each party agrees that all legal proceedings concerning

hereto or its respective affiliates, directors, officers, shareholders, employees or agents) shall be commenced exclusively in
the state and federal courts sitting in the City of New York. Each party hereby irrevocably submits to the exclusive jurisdiction

or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees

that such suit, action or proceeding is improper or is an inconvenient venue for such proceeding. Each party hereby irrevocably
waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing a copy
thereof via registered or certified mail or overnight delivery (with evidence of delivery) to such party at the address in effect
for notices to it under this Agreement and agrees that such service shall constitute good and sufficient service of process and
notice thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any other manner permitted
by law. The parties hereby waive all rights to a trial by jury. If either party shall commence an action or proceeding to enforce
any provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party
for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution
of such action or proceeding.


15. Loss
of Warrant.


Upon receipt by the Company of evidence of the loss, theft, destruction
or mutilation of this Warrant, and (in the case of loss, theft or destruction) of indemnity or security reasonably satisfactory
to the Company, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver a new
Warrant of like tenor and date.


16. Notice

to this Warrant to be given or made by Holder to or on the Company shall be sufficiently given or made if sent by overnight delivery

    	16



    	 



    

17. Limitation
on Issuance of Common Stock.


Notwithstanding anything herein to the contrary, the maximum number
of shares of Common Stock issued or issuable pursuant to this Warrant and all additional Warrants issued pursuant to Section 2.10
of the Facility Agreement may not exceed the aggregate number of shares of Common Stock which the Company may issue upon exercise
of the Warrants without violating NASDAQ Rule 5635(d).

Warrant to Purchase Common Stock

of

MAKO Surgical Corp.


THIS CERTIFIES that ____________ or any subsequent holder hereof
(“Holder”) has the right to purchase from MAKO Surgical Corp., a Delaware corporation, (the “Company”),
________ (______) fully paid and nonassessable shares of the Company’s common stock, $0.001 par value per share (“Common
Stock”), subject to adjustment as provided herein, at a price equal to the Exercise Price as defined in Section 3 below,
at any time during the Term (as defined below).


Holder agrees with the Company that this Warrant to Purchase Common
Stock of the Company (this “Warrant” or this “Agreement”) is issued and all rights hereunder shall be held
subject to all of the conditions, limitations and provisions set forth herein.


1. Date of
Issuance and Term.


This Warrant shall be deemed to be issued on ____________ (“Date
of Issuance”). The term of this Warrant begins on the Date of Issuance and ends at 5:00 p.m., New York City time, on the
date that is seven (7) years after the Date of Issuance (the “Term”). This Warrant was issued in conjunction with that
certain Facility Agreement (the “Facility Agreement”) and the Registration Rights Agreement (“Registration Rights
Agreement”) by and between the Company, Holder and __________, each dated May 7, 2012, entered into in conjunction herewith.


Notwithstanding anything herein to the contrary, the Company shall
not issue to the Holder, and the Holder may not acquire, a number of shares of Common Stock upon exercise of this Warrant to the
extent that, upon such exercise, the number of shares of Common Stock then beneficially owned by the Holder and its Affiliates
and any other persons or entities whose beneficial ownership of Common Stock would be aggregated with the Holder’s for purposes
of Section 13(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) (including shares held
by any “group” of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership
of securities or rights to acquire securities that have limitations on the right to convert, exercise or purchase similar to the
limitation set forth herein) would exceed 9.985% of the total number of shares of Common Stock then issued and outstanding (the
“9.985% Cap”), provided, however, that the 9.985% Cap shall not apply with respect to the issuance of shares of Common
Stock pursuant to a Cashless Major Exercise (as defined below) in connection with a Major Transaction (as defined below) covered
by the provisions of Section 5(c)(i)(A)(1) below in which the Company is not the surviving entity (a “Non-Surviving Change
of Control Transaction”) to the extent that the number of shares beneficially owned by the Holder and its affiliates in the
successor entity immediately following consummation of such Non-Surviving Change of Control Transaction does not exceed 9.985%
of the outstanding common stock of such successor entity and provided, further, that the 9.985% Cap shall only apply to the extent
that the Common Stock is deemed to constitute an “equity security” pursuant to Rule 13d-1(i) promulgated under the
Exchange Act. For purposes hereof, “group” has the meaning set forth in Section 13(d) of the Exchange Act and
applicable regulations of the Securities and Exchange Commission (the “SEC”), and the percentage held by the Holder
shall be determined in a manner consistent with the provisions of Section 13(d) of the Exchange Act. Upon the written request
of the Holder, the Company shall, within two (2) Trading Days, confirm orally and in writing to the Holder the number of shares
of Common Stock then outstanding.



    	 



    	 



    

“Affiliate” means any person or entity that, directly
or indirectly through one or more intermediaries, controls or is controlled by or is under common control with a person or entity,
as such terms are used in and construed under Rule 144 under the Securities Act of 1933, as amended (the “Securities Act”).
With respect to a Holder of Warrants, any investment fund or managed account that is managed on a discretionary basis by the same
investment manager as such Holder will be deemed to be an Affiliate of such Holder.


“Holder” means ______ and any transferee or assignee
pursuant to the terms of this Warrant.


2. Exercise.


(a) Manner
of Exercise. Beginning on the Date  of Issuance and continuing during the Term, this Warrant may be Exercised as to all
or any lesser number of whole shares of Common Stock covered hereby (the “Warrant Shares” or
the “Shares”) upon surrender of this Warrant, with the Exercise Form attached hereto as Exhibit A
(the “Exercise Form”) duly completed and executed, together with the full Exercise Price (as defined below, which
may be satisfied by a Cash Exercise or a Cashless Exercise, as each is defined below) for each share of Common Stock as to
which this Warrant is Exercised, at the office of the Company, 2555 Davie Road, Fort Lauderdale, FL 33317,
Phone: (954) 927-2044, Fax: (954) 707-5360, electronic mail:adminteam@makosurgical.com), or at such other office or
agency as the Company may designate in writing, by overnight mail, with an advance copy of the Exercise Form sent to the
Company by facsimile or electronic mail (such surrender and payment of the Exercise Price hereinafter called the
“Exercise” of this Warrant).


(b) Date
of Exercise. The “Date of Exercise” of the Warrant shall be defined as the date that the Exercise Form attached
hereto as Exhibit A, completed and executed, is sent by facsimile or electronic mail to the Company, provided that
the original Warrant and Exercise Form are received by the Company and the Exercise Price is satisfied, each as soon as practicable
thereafter but in no event later than two (2) business days following the date of such facsimile or electronic mail. Alternatively,
the Date of Exercise shall be defined as the date the original Exercise Form is received by the Company, if Holder has not sent
advance notice by facsimile or electronic mail. Upon delivery of the Exercise Form to the Company by facsimile, electronic mail
or otherwise, the Holder shall be deemed for all corporate purposes to have become the holder of record of the Warrant Shares with
respect to which this Warrant has been Exercised, irrespective of the date such Warrant Shares are credited to the Holder’s
Depository Trust Company (“DTC”) account or the date of delivery of the certificates evidencing such Warrant Shares,
as the case may be; provided, however, that in the event of a Cashless Major Exercise in respect of a Non-Surviving Change of Control
Transaction, the Holder shall be deemed to have become the holder of record of the shares issuable upon such exercise immediately
prior to the consummation of such Non-Surviving Change of Control Transaction.


(c) Delivery
of Common Stock Upon Exercise. Within three (3) business days after the Date of Exercise (but, in the case of a Cash Exercise,
within two (2) business days following the Company’s receipt of the full Exercise Price, if later) or, in the case of a Cashless
Major Exercise or a Cashless Default Exercise (each as defined in Section 5(c) below), within the period provided in Section 5(c)(iv)
or Section 3(c), as applicable (the “Delivery Period”), the Company shall issue and deliver (or cause its Transfer
Agent to issue and deliver) in accordance with the terms hereof to or upon the order of the Holder that number of shares of Common
Stock (“Exercise Shares”) for the portion of this Warrant converted as shall be determined in accordance herewith.
Upon the Exercise of this Warrant or any part hereof, the Company shall, at its own cost and expense, take all necessary action,
including obtaining and delivering an opinion of counsel, to assure that the Company’s transfer agent (the “Transfer
Agent”) shall issue stock certificates in the name of Holder (or its nominee) or such other persons as designated by Holder
and in such denominations to be specified at Exercise representing the number of shares of Common Stock issuable upon such Exercise.
The Company warrants that no instructions other than these instructions have been or will be given to the Transfer Agent and that,
unless waived by the Holder, this Warrant and the Exercise Shares will be free-trading, and freely transferable, and will not contain
a legend restricting the resale or transferability of the Exercise Shares if the Unrestricted Conditions (as defined below) are
met.



    	2



    	 



    

(d) Delivery
Failure. In addition to any other remedies which may be available to the Holder, in the event that the Company fails for any
reason to effect delivery of the Exercise Shares by the end of the Delivery Period (a “Delivery Failure”), the Holder
will be entitled to revoke all or part of the relevant Exercise Form by delivery of a notice to such effect to the Company whereupon
the Company and the Holder shall each be restored to their respective positions immediately prior to the delivery of such notice,
except that the liquidated damages described herein shall be payable through the date notice of revocation or rescission is given
to the Company.


(e) Legends.


(i) Restrictive
Legend. The Holder understands that until such time as this Warrant, the Exercise Shares and the Failure Payment Shares have
been registered under the Securities Act as contemplated by the Registration Rights Agreement or otherwise may be sold pursuant
to Rule 144 under the Securities Act or an exemption from registration under the Securities Act without any restriction as to the
number of securities as of a particular date that can then be immediately sold, this Warrant, the Exercise Shares and the Failure
Payment Shares, as applicable, may bear a restrictive legend in substantially the following form (and a stop-transfer order may
be placed against transfer of the certificates for such securities):


“THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE
NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS. THE SECURITIES MAY NOT BE
SOLD, TRANSFERRED, ASSIGNED, PLEDGED, HYPOTHECATED OR OTHERWISE DISPOSED OF IN THE ABSENCE OF AN EFFECTIVE REGISTRATION STATEMENT
FOR THE SECURITIES UNDER SAID ACT, OR PURSUANT TO AN EXEMPTION FROM REGISTRATION UNDER SAID ACT INCLUDING, WITHOUT LIMITATION,
PURSUANT TO RULES 144 OR 144A UNDER SAID ACT OR PURSUANT TO A PRIVATE SALE EFFECTED UNDER APPLICABLE FORMAL OR INFORMAL SEC INTERPRETATION
OR GUIDANCE, SUCH AS A SO-CALLED “4(1) AND A HALF” SALE.”


“THE SALE, TRANSFER OR ASSIGNMENT OF THE SECURITIES REPRESENTED
BY THIS CERTIFICATE ARE SUBJECT TO THE TERMS AND CONDITIONS OF A CERTAIN REGISTRATION RIGHTS AGREEMENT DATED AS OF MAY 7, 2012,
AS AMENDED FROM TIME TO TIME, AMONG THE COMPANY AND CERTAIN HOLDERS OF ITS OUTSTANDING SECURITIES. COPIES OF SUCH AGREEMENT MAY
BE OBTAINED AT NO COST BY WRITTEN REQUEST MADE BY THE HOLDER OF RECORD OF THIS CERTIFICATE TO THE SECRETARY OF THE COMPANY.”


(ii) Removal
of Restrictive Legends. This Warrant and the certificates evidencing the Exercise Shares and the Failure Payment Shares, as
applicable, shall not contain any legend restricting the transfer thereof (including the legend set forth above in subsection 2(e)(i)):
(A) while a registration statement (including a Registration Statement, as defined in the Registration Rights Agreement) covering
the sale or resale of such security is effective under the Securities Act, or (B) following any sale of such Warrant, Exercise
Shares and/or Failure Payment Shares pursuant to Rule 144, or (C) if such Warrant, Exercise Shares and/or Failure Payment
Shares are eligible for sale under Rule 144(b)(1), or (D) if such legend is not required under applicable requirements of
the Securities Act (including judicial interpretations and pronouncements issued by the staff of the SEC) (collectively, the “Unrestricted
Conditions”). The Company shall cause its counsel to issue a legal opinion to the Transfer Agent promptly after the Effective
Date if required by the Company’s transfer agent to effect the issuance of the Exercise Shares or the Failure Payment Shares,
as applicable, without a restrictive legend or removal of the legend hereunder. If the Unrestricted Conditions are met at the time
of issuance of this Warrant, the Exercise Shares or the Failure Payment Shares, then such Warrant, Exercise Shares or Failure Payment
Shares, as applicable, shall be issued free of all legends. The Company agrees that following the Effective Date at such time as
the Unrestricted Conditions are met or such legend is otherwise no longer required under this Section 2(e), it will, no later
than three (3) Trading Days following the delivery (the “Unlegended Shares Delivery Deadline”) by the Holder to the
Company or the Transfer Agent of this Warrant and a certificate representing Exercise Shares and/or Failure Payment Shares, as
applicable, issued with a restrictive legend (such third Trading Day, the “Legend Removal Date”), deliver or cause
to be delivered to such Holder a certificate (or electronic transfer) representing such shares that is free from all restrictive
and other legends. For purposes hereof, “Effective Date” shall mean the date that the Registration Statement that the
Company is required to file pursuant to the Registration Rights Agreement has been declared effective by the SEC.



    	3



    	 



    

(iii) Sale
of Unlegended Shares. Holder agrees that the removal of the restrictive legend from this Warrant and any certificates representing
securities as set forth in Section 2(e) above is predicated upon the Company’s reliance that the Holder will sell this
Warrant or any Exercise Shares and/or any Failure Payment Shares, as applicable, pursuant to either the registration requirements
of the Securities Act, including any applicable prospectus delivery requirements, or an exemption therefrom, and that if such securities
are sold pursuant to a Registration Statement, they will be sold in compliance with the plan of distribution set forth therein.


(f) Cancellation
of Warrant. This Warrant shall be canceled upon the full Exercise, of this Warrant, and, as soon as practical after the Date
of Exercise, Holder shall be entitled to receive Common Stock for the number of shares purchased upon such Exercise of this Warrant,
and if this Warrant is not Exercised in full, Holder shall be entitled to receive a new Warrant (containing terms identical to
this Warrant) representing any unexercised portion of this Warrant in addition to such Common Stock.


(g) Holder
of Record. Each person in whose name any Warrant for shares of Common Stock is issued shall, for all purposes, be deemed to
be the Holder of record of such shares on the Date of Exercise of this Warrant, irrespective of the date of delivery of the Common
Stock purchased upon the Exercise of this Warrant. Prior to the exercise of this Warrant, nothing in this Warrant shall be construed
as conferring upon Holder any rights as a stockholder of the Company.


(h) Delivery
of Electronic Shares. In lieu of delivering physical certificates representing the Common Stock issuable upon Exercise or legend
removal, or representing Failure Payment Shares, provided the Transfer Agent is participating in the DTC Fast Automated Securities
Transfer (“FAST”) program, upon written request of the Holder, the Company shall use its best efforts to cause its
Transfer Agent to electronically transmit the Common Stock issuable upon Exercise to the Holder by crediting the account of the
Holder’s prime broker with DTC through its Deposit Withdrawal Agent Commission (DWAC) system. The time periods for delivery
and penalties described herein shall apply to the electronic transmittals described herein. Any delivery not effected by electronic
transmission shall be effected by delivery of physical certificates.


(i) Buy-In.
In addition to any other rights available to the Holder, if the Company fails to cause its Transfer Agent to transmit to the Holder
a certificate or certificates, or electronic shares through DWAC, representing the Exercise Shares pursuant to an Exercise on or
before the Delivery Period (other than a failure caused by any incorrect or incomplete information provided by Holder to the Company
hereunder), and if after such date the Holder is required by its broker to purchase (in an open market transaction or otherwise)
or the Holder’s brokerage firm otherwise purchases shares of Common Stock to deliver in satisfaction of a sale by the Holder
of the Exercise Shares which the Holder anticipated receiving upon such Exercise (a “Buy-In”), then the Company shall
(1) pay in cash to the Holder the amount by which (x) the Holder’s total purchase price (including brokerage commissions,
if any) for the shares of Common Stock so purchased exceeds (y) the amount obtained by multiplying (A) the number of
Exercise Shares that the Company was required to deliver to the Holder in connection with the Exercise at issue times and (B) the
price at which the sell order giving rise to such purchase obligation was executed, and (2) at the option of the Holder, either
reinstate the portion of the Warrant and equivalent number of Exercise Shares for which such Exercise was not honored or deliver
to the Holder the number of shares of Common Stock that would have been issued had the Company timely complied with its Exercise
and delivery obligations hereunder. For example, if the Holder purchases Common Stock having a total purchase price of $11,000
to cover a Buy-In with respect to an attempted Exercise to cover the sale of Common Stock with an aggregate sale price giving rise
to such purchase obligation of $10,000, under clause (1) of the immediately preceding sentence the Company shall be required
to pay the Holder $1,000. The Holder shall provide the Company written notice indicating the amounts payable to the Holder in respect
of the Buy-In, together with applicable confirmations and other evidence reasonably requested by the Company. Nothing herein shall
limit a Holder’s right to pursue any other remedies available to it hereunder, at law or in equity including, without limitation,
a decree of specific performance and/or injunctive relief with respect to the Company’s failure to timely deliver certificates
representing shares of Common Stock upon Exercise of the Warrant as required pursuant to the terms hereof.

3. Payment
of Warrant Exercise Price for Cash Exercise or Cashless Exercise; Cashless Major Exercise and Cashless Default Exercise.


(a) Exercise
Price. The Exercise Price (“Exercise Price”) shall initially equal 120% of the mean of the Closing Prices (as defined
below) of the Common Stock for each of the five (5) consecutive Trading Days beginning with the first full Trading Day following
receipt by the Lenders of a Disbursement Request (as such terms are defined in the Facility Agreement), subject to adjustment pursuant
to the terms hereof, including but not limited to Section 5 below. The Company’s calculation of the Exercise Price shall
be deemed to be final and binding upon the Holder unless, within two (2) business days of receipt of such notice, the Holder sends
a notice by facsimile ((954) 707-5360) to the Company disputing the calculation of the Exercise Price. If the Holder and the
Company are unable to agree upon the Exercise Price within two (2) business days following the receipt by the Company of the Holder’s
notice disputing the calculation of the exercise price, then the dispute shall be submitted by the Company to the Company’s
independent outside accountant and resolved in accordance with Section 3(d). As used herein, the “Closing Price” for
the Common Stock as of any date means the closing trade price (based on regular hours trading) of the Common Stock on NASDAQ, as
reported by Bloomberg or, if NASDAQ is not the principal trading market for the Common Stock, the closing trade price of the Common
Stock on the principal securities exchange or trading market where the Common Stock is listed or traded as reported by Bloomberg
or, if no last closing trade price is reported for the Common Stock by Bloomberg, the average of the bid prices of any market makers
for the Common Stock in the over the counter market maintained by the Financial Industry Regulatory Authority, Inc. or in the “pink
sheets” (or any successor) maintained by the OTC Markets Group, Inc.


Payment of the Exercise Price may be made by either of the following,
or a combination thereof, at the election of Holder:


(i) Cash Exercise:
The Holder, at its option, may exercise this Warrant in cash, bank or cashier’s check, wire transfer or through a reduction
of an amount of principal outstanding under any Notes (as defined in the Facility Agreement) in accordance with Section 2.3 of
the Facility Agreement, then held by the Holder (a “Cash Exercise”); or


(ii) Cashless
Exercise: The Holder may exercise this Warrant in a cashless exercise transaction. In order to effect a Cashless Exercise,
the Holder shall surrender this Warrant at the principal office of the Company together with notice of cashless election, in which
event the Company shall issue Holder a number of shares of Common Stock computed using the following formula (a “Cashless
Exercise”):


X = Y (A-B)/A


	where:	X = the number of shares of Common Stock to be issued to Holder.



Y = the number of shares of Common Stock for which this Warrant
is being Exercised.


A = the Market Price of one (1) share of Common Stock (for
purposes of this Section 3(a)(ii), where “Market Price,” as of any date, means the Volume Weighted Average Price
(as defined herein) of the Company’s Common Stock for the ten (10) consecutive Trading Day period immediately preceding the
date in question.


B = the Exercise Price.



    	5



    	 



    



As used herein, “Volume Weighted Average Price”
for any security as of any date means the volume weighted average sale price on The NASDAQ Global Select Market (“NASDAQ”)
as reported by, or based upon data reported by Bloomberg Financial Markets or an equivalent, reliable reporting service mutually
acceptable to and hereinafter designated by holders of a majority in interest of the Warrants and the Company (“Bloomberg”)
or, if NASDAQ is not the principal trading market for such security, the volume weighted average sale price of such security on
the principal securities exchange or trading market where such security is listed or traded as reported by Bloomberg or, if no
volume weighted average sale price is reported for such security by Bloomberg, then the last closing trade price of such security
as reported by Bloomberg, or, if no last closing trade price is reported for such security by Bloomberg, the average of the bid
prices of any market makers for such security that are listed in the over the counter market by the Financial Industry Regulatory
Authority, Inc. or on the “over the counter” Bulletin Board (or any successor) or in the “pink sheets”
(or any successor) by the OTC Markets Group, Inc. If the Volume Weighted Average Price cannot be calculated for such security on
such date in the manner provided above, the Volume Weighted Average Price shall be the fair market value as mutually determined
by the Company and the Holders of a majority in interest of the Warrants being Exercised for which the calculation of the Volume
Weighted Average Price is required in order to determine the Exercise Price of such Warrants.  “Trading
Day” shall mean any day on which the Common Stock is traded for any period on NASDAQ, or on the principal securities exchange
or other securities market on which the Common Stock is then being traded. 


For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended, understood and acknowledged that the Common Stock issuable upon Exercise of this Warrant in a Cashless Exercise transaction
shall be deemed to have been acquired at the time this Warrant was issued. Moreover, it is intended, understood and acknowledged
that the holding period for the Common Stock issuable upon Exercise of this Warrant in a Cashless Exercise transaction shall be
deemed to have commenced on the date this Warrant was issued.


(b) Cashless Major Exercise. To the extent the Holder shall
exercise this Warrant or any portion thereof as a Cashless Major Exercise pursuant to Section 5(c)(i) below, the Holder shall surrender
this Warrant at the principal office of the Company together with the Exercise Form indicating that the Holder is exercising this
Warrant (or such portion thereof) pursuant to a Cashless Major Exercise, in which event the Company shall issue a number of shares
of Common Stock equal to the Black-Scholes Value (as defined in Section 5(c)(iii) below) of the Warrant (or such applicable portion
being exercised) divided by the closing price of the Common Stock on the principal securities exchange or other securities market
on which the Common Stock is then traded on the Trading Day immediately preceding the date on which the applicable Major Transaction
is consummated.


(c) Cashless Default Exercise. To the extent the Holder exercises
this Warrant as a Cashless Default Exercise pursuant to Section 11(b)(i) below, the Holder shall surrender this Warrant to the
principal office of the Company together with the Exercise Form indicating that the Holder is exercising this Warrant pursuant
to a Cashless Default Exercise, in which event the Company shall, at the election of the Company, (i) issue to the Holder, within
five (5) Trading Days of the applicable Default Notice, a number of shares of Common Stock (which shares shall be valued at the
Volume Weighted Average Price for the five (5) Trading Days prior to the applicable Default Notice) equal to the Black-Scholes
value (determined by use of the Black-Scholes Option Pricing Model using the criteria set forth on Schedule I hereto) of the remaining
unexercised portion of this Warrant on the date of such Default Notice (the “Cashless Default Exercise Amount”), or
(ii) pay the Cashless Default Exercise Amount to the Holder in cash.


(b) Dispute
Resolution. Subject to the provisions of Section 3(a), in the case of a dispute as to the determination of the closing price
or Volume Weighted Average Price of the Company’s Common Stock or the arithmetic calculation of the Exercise Price, Market
Price or any Major Transaction Warrant Early Termination Price, the Company shall submit the disputed determinations or arithmetic
calculations via facsimile within two (2) business days of receipt, or deemed receipt, of the Exercise Notice or Major Transaction
Early Termination Notice, or other event giving rise to such dispute, as the case may be, to the Holder. If the Holder and the
Company are unable to agree upon such determination or calculation within two (2) business days of such disputed determination
or arithmetic calculation being submitted to the Holder, then the Company shall, within two (2) business days submit via facsimile
(i) the disputed determination of the closing price or the Volume Weighted Average Price of the Company’s Common Stock
to an independent, reputable investment bank selected by the Company and approved by the Holder, which approval shall not be unreasonably
withheld or (ii) the disputed arithmetic calculation of the Exercise Price, Market Price or any Major Transaction Warrant
Early Termination Price to the Company’s independent, outside accountant. The Company shall use reasonable commercial efforts
to cause the investment bank or the accountant, as the case may be, to perform the determinations or calculations and notify the
Company and the Holder of the results no later than five (5) business days from the time it receives the disputed determinations
or calculations. Such investment bank’s or accountant’s determination or calculation, as the case may be, shall be
binding upon all parties absent demonstrable error, and the Company and the Holder shall each pay one half of the fees and costs
of such investment banker or accountant.

4. Transfer
and Registration.


(a) Transfer
Rights. Subject to the provisions of Section 8 of this Warrant, this Warrant may be transferred on the books of the Company,
in whole or in part, in person or by attorney, upon surrender of this Warrant properly completed and endorsed. This Warrant shall
be canceled upon such surrender and, as soon as practicable thereafter, the person to whom such transfer is made shall be entitled
to receive a new Warrant or Warrants as to the portion of this Warrant transferred, and Holder shall be entitled to receive a new
Warrant as to the portion hereof retained.


(b) Registrable
Securities. The Common Stock issuable upon the Exercise of this Warrant has registration rights pursuant to the Registration
Rights Agreement.


5. Adjustments
Upon Certain Events.


(a) Participation.
The Holder, as the holder of this Warrant, shall be entitled to receive such dividends paid and distributions of any kind made
to the holders of Common Stock of the Company to the same extent as if the Holder had Exercised this Warrant into Common Stock
(without regard to any limitations on exercise herein or elsewhere and without regard to whether or not a sufficient number of
shares are authorized and reserved to effect any such exercise and issuance) and had held such shares of Common Stock on the record
date for such dividends and distributions. Payments under the preceding sentence shall be made concurrently with the dividend or
distribution to the holders of Common Stock.


(b) Recapitalization
or Reclassification. If the Company shall at any time effect a stock split, payment of stock dividend, recapitalization, reclassification
or other similar transaction of such character that the shares of Common Stock shall be changed into or become exchangeable for
a larger or smaller number of shares, then upon the effective date thereof, the number of shares of Common Stock which Holder shall
be entitled to purchase upon Exercise of this Warrant shall be increased or decreased, as the case may be, in direct proportion
to the increase or decrease in the number of shares of Common Stock by reason of such stock split, payment of stock dividend, recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the case of an increase in the number of shares, proportionally
decreased and, in the case of decrease in the number of shares, proportionally increased. The Company shall give Holder the same
notice it provides to holders of Common Stock of any transaction described in this Section 5(b).


(c) Rights
Upon Major Transaction.


(i) Major Transaction. In the event that a Major Transaction
(as defined below) occurs, then (1) in the case of a Major Transaction covered by the provisions
of Section 5(c)(i)(A) below in which the Company is not the surviving entity and in which the consideration consists solely of
securities of a Publicly Traded Successor Entity, as defined below (a “Qualified Change of Control Transaction”), the
Company shall have the right to treat such Major Transaction as an Assumption, (2) in the case of a Cash-Out Major Transaction,
and in the case of a Mixed Major Transaction to the extent of the percentage of the cash consideration in the Mixed Major Transaction
(determined in accordance with the definition of a Mixed Major Transaction below), the Holder, at its option, may require the Company
to redeem the Holder’s outstanding Warrants in accordance with Section 5(c)(iii) below and (3) in the case of all other
Major Transactions (including, without limitation, a Qualified Change of Control Transaction for which the Company does not make
an Assumption Election (as defined below)), and in the case of a Mixed Major Transaction to the extent of the percentage of the
consideration represented by securities of a Successor Entity in the Mixed Major Transaction, the Holder shall have the right to
exercise this Warrant as a Cashless Major Exercise. In the event the Holder shall not have exercised any of its rights under clauses
(2) or (3) above within the applicable time periods set forth herein, then the Major Transaction shall be treated as an Assumption
(as defined below) in accordance with Section 5(c)(ii) below. Notwithstanding anything herein to the contrary, the Holder may waive
its rights under this Section 5(c) with respect to any Major Transaction in which event none of the provisions of this Section
5(c) shall apply with respect to such Major Transaction. In the event of a Major Transaction in which all shares of Common Stock
are cancelled and converted into the right to receive cash and/or securities of Another Entity (as defined below), then, any portion
of this Warrant that is neither redeemed, assumed or exercised pursuant to the terms of this Warrant prior to the closing of such
Major Transaction, shall automatically and immediately convert into shares of Common Stock, and shall be deemed to have been exercised
pursuant to a Cashless Exercise, immediately prior to the consummation of such Major Transaction. Each of the following events
shall constitute a “Major Transaction”.



    	7



    	 



    

(A) a consolidation,
merger, exchange of shares, recapitalization, reorganization, business combination or other similar event, (1) following which
the holders of Common Stock immediately preceding such consolidation, merger, exchange, recapitalization, reorganization, combination
or event either (a) no longer hold a majority of the shares of Common Stock or (b) no longer have the ability to elect
a majority of the board of directors of the Company or (2) as a result of which shares of Common Stock shall be changed into
(or the shares of Common Stock become entitled to receive) a different class or classes of stock or securities of the Company or
another entity (collectively, a “Change of Control Transaction”);


(B) the sale
or transfer in one transaction or a series of related transactions of (i) all or substantially all of the assets of the Company,
or (ii) assets of the Company for a purchase price equal to more than 50% of the Enterprise Value (as defined below) of the Company.
For purposes of this clause (B), “Enterprise Value” shall mean (I) the product of (x) the number of issued and outstanding
shares of Common Stock on the date the Company delivers the Major Transaction Notice (defined below) multiplied by (y) the per
share closing price of the Common Stock on such date plus (II) the amount of the Company’s debt as shown on the latest financial
statements filed with the SEC (the “Current Financial Statements”) less (III) the amount of cash and cash equivalents
of the Company as shown on the Current Financial Statements;


(C) a purchase,
tender or exchange offer made to the holders of outstanding shares of Common Stock, such that following such purchase, tender or
exchange offer a Change of Control Transaction shall have occurred; or


(D) the liquidation,
bankruptcy, insolvency, dissolution or winding-up (or the occurrence of any analogous proceeding) of the Company.


(ii) Assumption.
The Company shall not enter into or be party to a Major Transaction that is to be treated as an Assumption pursuant to Section
5(c)(i), unless (A) the successor entity resulting from such Major Transaction (in each case, a “Successor Entity”),
assumes in writing all of the obligations of the Company under this Warrant, the Facility Agreement (but only if there will be
an outstanding balance under the Facility Agreement immediately following the closing of the Major Transaction) and the Registration
Rights Agreement  in accordance with the provisions of this Section (ii) pursuant to written agreements in form and substance
reasonably satisfactory to the Holder and approved by the Holder prior to such Major Transaction (not to be unreasonably withheld
or delayed), including agreements to deliver to each holder of Warrants in exchange for such Warrants a security of the Successor
Entity evidenced by a written instrument substantially similar in form and substance to the Warrants, including, without limitation,
representing the appropriate number of shares of the Successor Entity, having similar exercise rights as the Warrants (including
but not limited to a similar Exercise Price and similar Exercise Price adjustment provisions based on the price per share or conversion
ratio to be received by the holders of Common Stock in the Major Transaction) and similar registration rights as provided by the
Registration Rights Agreement, reasonably satisfactory to the Holder and (B) the Successor Entity is a Public Successor Entity.
Upon the occurrence of any Major Transaction, any Successor Entity shall succeed to, and be substituted for (so that from and after
the date of such Major Transaction, the provisions of this Warrant and the Registration Rights Agreement referring to the “Company”
shall refer instead to the Successor Entity), and may exercise every right and power of the Company and shall assume all of the
obligations of the Company under this Warrant with the same effect as if such Successor Entity had been named as the Company herein.
Upon consummation of the Major Transaction, the Successor Entity shall deliver to the Holder confirmation that there shall be issued
upon exercise or redemption of this Warrant at any time after the consummation of the Major Transaction, in lieu of the shares
of Common Stock (or other securities, cash, assets or other property) issuable upon the exercise of the Warrants prior to such
Major Transaction, such shares of publicly traded common stock (or their equivalent) of the Successor Entity, as adjusted in accordance
with the provisions of this Warrant. The provisions of this Section shall apply similarly and equally to successive Major Transactions
and shall be applied without regard to any limitations on the exercise of this Warrant other than any applicable beneficial ownership
limitations. Any assumption of Company obligations under this paragraph shall be referred to herein as an “Assumption”



    	8



    	 



    

 


(iii) Notice;
Major Transaction Early Termination Right; Notice of Cashless Major Exercise. At least thirty (30) days prior to the consummation
of any Major Transaction, but, in any event, within five (5) Business Days following the first to occur of (x) the date of
the public announcement of such Major Transaction if such announcement is made before 4:00 p.m., New York City time, or (y) the
day following the public announcement of such Major Transaction if such announcement is made on and after 4:00 p.m., New York City
time, the Company shall deliver written notice thereof via facsimile and overnight courier to the Holder (a “Major Transaction
Notice”). The Major Transaction Notice with respect to a Qualified Change of Control Transaction shall also state whether
the Company is electing to treat such Major Transaction as an Assumption (an “Assumption Election”). At any time during
the period beginning after the Holder’s receipt of a Major Transaction Notice and ending five (5) Trading Days prior to the
consummation of such Major Transaction (the “Early Termination Period”), the Holder may require the Company to redeem
(an “Early Termination Upon Major Transaction”) all or any portion of this Warrant not treated as an Assumption and
not eligible to be treated as a Cashless Major Exercise (without taking into consideration the 9.985% Cap) by delivering written
notice thereof (“Major Transaction Early Termination Notice”) to the Company, which Major Transaction Early Termination
Notice shall indicate the portion of this Warrant, measured by the number of Shares then subject to this Warrant (the “Early
Termination Principal Amount”) of the Warrant that the Holder is electing to have redeemed. The portion of this Warrant subject
to early termination pursuant to this Section 5(c)(iii) (the “Redeemable Shares”), shall be redeemed by the Company
at a price (the “Major Transaction Warrant Early Termination Price”) payable in cash equal to the “Black Scholes
Value” of the Redeemable Shares determined by use of the Black Scholes Option Pricing Model using the criteria set forth
in Schedule 1 hereto (the “Black Scholes Value”). In the event the Major Transaction Notice relating to a Qualified
Change of Control Transaction includes an Assumption Election, the Holder shall send written notice to the Company within the Early
Termination Period if the Holder elects to waive this Section 5(c) in its entirety in which event no Assumption shall occur.


To the extent the Holder shall elect to effect a Cashless Major Exercise
in respect of a Major Transaction, the Holder shall deliver its exercise notice in accordance with Section 3(b), within the Early
Termination Period.


(iv) Escrow;
Payment of Major Transaction Warrant Early Termination Price. Following the receipt of a Major Transaction Early Termination
Notice or a Cashless Major Exercise from the Holder, the Company shall not effect a Major Transaction that is being treated as
an early termination or is eligible to be treated as a Cashless Major Exercise unless either (a) it obtains the written agreement
of the Successor Entity that payment of the Major Transaction Warrant Early Termination Price and/or issuance of the applicable
Exercise Shares shall be made to the Holder prior to consummation of such Major Transaction and such issuance or payment shall
be a condition precedent to consummation of such Major Transaction or (b) it shall first place into an escrow account with an independent
escrow agent, at least three (3) business days prior to the closing date of the Major Transaction (the “Major Transaction
Escrow Deadline”), an amount in shares of Common Stock or cash, as applicable, equal to the Major Transaction Warrant Early
Termination Price and/or applicable Exercise Shares. Concurrently upon closing of such Major Transaction, the Company shall pay
or shall instruct the escrow agent to pay the Major Transaction Warrant Early Termination Price and/or to deliver the applicable
Exercise Shares to the Holder. For purposes of determining the amount required to be placed in escrow pursuant to the provisions
of this subsection (iv) and without affecting the amount of the actual Major Transaction Warrant Early Termination Price and/or
applicable Exercise Shares, the calculation of the price referred to in clause (1) of the first column of Schedule 1 hereto
with respect to Stock Price shall be determined based on the Closing Market Price (as defined on Schedule I) of the Common Stock
on the Trading Day immediately preceding the date that the funds and/or applicable Exercise Shares, as applicable, are deposited
with the escrow agent.



    	9



    	 



    

(v) Injunction.
Following the receipt of a Major Transaction Early Termination Notice or notice of a Cashless Major Exercise from the Holder, in
the event that the Company attempts to consummate a Major Transaction without either (1) placing the Major Transaction Warrant
Early Termination Price or applicable Exercise Shares, as applicable, in escrow in accordance with subsection (iv) above, (2) payment
of the Major Transaction Warrant Early Termination Price or issuance of the applicable Exercise Shares, as applicable, to the Holder
prior to consummation of such Major Transaction or (3) obtaining the written agreement of the Successor Entity described in subsection
(iv) above, the Holder shall have the right to apply for an injunction in any state or federal courts sitting in the City of New
York, borough of Manhattan to prevent the closing of such Major Transaction until the Major Transaction Warrant Early Termination
Price is paid to the Holder, in full or the applicable Exercise Shares are delivered or deposited in escrow, as applicable.


An early termination required by this Section 5(c) shall be
made in accordance with the provisions of Section 12 and shall have priority to payments to holders of Common Stock in connection
with a Major Transaction , and to the extent an early termination required by this Section 5(c)(iii) are deemed or determined
by a court of competent jurisdiction to be prepayments of the Warrant by the Company, such early termination shall be deemed to
be voluntary prepayments. Notwithstanding anything to the contrary in this Section 5, until the Major Transaction Warrant Early
Termination Price is paid in full, this Warrant may be exercised, in whole or in part, by the Holder into shares of Common Stock,
or in the event the Exercise Date is after the consummation of the Major Transaction, shares of publicly traded common stock (or
their equivalent) of the Successor Entity pursuant to Section 5(c). The parties hereto agree that in the event of the early termination
of any portion of the Warrant under this Section 5(c), the Holder’s damages would be uncertain and difficult to estimate
because of the parties’ inability to predict future interest rates and the uncertainty of the availability of a suitable
substitute investment opportunity for the Holder. Accordingly, any premium due under this Section 5(c) is intended by the
parties to be, and shall be deemed, a reasonable estimate of the Holder’s actual loss of its investment opportunity and not
as a penalty.


For purposes hereof:


“Another Entity” shall mean an entity in which the holders
of a majority of the shares of Common Stock of the Company immediately prior to the consummation of a Major Transaction do not
hold a majority of the equity securities in such entity.


“Cash-Out Major Transaction” means a Major Transaction
in which the consideration payable to holders of Common Stock in connection with the Major Transaction consists solely of cash.


“Cashless Default Exercise” shall mean an exercise of
this Warrant as a “Cashless Default Exercise” in accordance with Section 3(c) and 11(b) hereof.


“Cashless Major Exercise” shall mean an exercise of this
Warrant or portion thereof as a “Cashless Major Exercise” in accordance with Section 3(b) and 5(c)(i) hereof.


“Eligible Market” means the over the counter Bulletin
Board, the New York Stock Exchange, Inc., the NYSE Arca, the NASDAQ Capital Market, the NASDAQ Global Market, the NASDAQ Global
Select Market or the NYSE Alternext U.S.


“Mixed Major Transaction” means a Major Transaction in
which the consideration payable to the stockholders of the Company consists partially of cash and partially of securities of a
Successor Entity. If the Successor Entity is a Publicly Traded Successor Entity, the percentage of consideration represented by
securities of such Successor Entity shall be equal to the percentage that the value of the aggregate anticipated number of shares
of the Publicly Traded Successor Entity to be issued to holders of Common Stock of the Company represents in comparison to the
aggregate value of all consideration, including cash consideration, in such Mixed Major Transaction, as such values are set forth
in any definitive agreement for the Mixed Major Transaction that has been executed at the time of the first public announcement
of the Major Transaction or, if no such value is determinable from such definitive agreement, based on the closing market price
for shares of the Publicly Traded Successor Entity on its principal securities exchange on the Trading Day preceding the first
public announcement of the Mixed Major Transaction. If the Successor Entity is a Private Successor Entity, the percentage of consideration
represented by securities of such Successor Entity shall be determined in good-faith by the Company's Board of Directors



    	10



    	 



    

“Parent Entity” of a Person means an entity that, directly
or indirectly, controls the applicable Person and whose common stock or equivalent equity security is quoted or listed on an Eligible
Market, or, if there is more than one such Person or Parent Entity, the Person or Parent Entity with the largest public market
capitalization as of the date of consummation of a Major Transaction.


“Person” means an individual, a limited liability company,
a partnership, a joint venture, a corporation, a trust, an unincorporated organization, any other entity and a government or any
department or agency thereof.


“Private Successor Entity” means a Successor Entity that
is not a Publicly Traded Successor Entity.


“Publicly Traded Successor Entity” means a Successor
Entity that is a publicly traded corporation whose common stock is quoted on or listed for trading on an Eligible Market (as defined
above).


“Successor Entity” means any Person purchasing the Company’s
assets or Common Stock, or any successor entity resulting from such Major Transaction, or if the Warrant is to be exercisable for
shares of capital stock of its Parent Entity (as defined above), its Parent Entity.


(d) Exercise
Price Adjusted. As used in this Warrant, the term “Exercise Price” shall mean the purchase price per share specified
in Section 3(a) of this Warrant, until the occurrence of an event stated in this Section 5 or otherwise set forth in
this Warrant, and thereafter shall mean said price as adjusted from time to time in accordance with the provisions of said subsection.
No adjustment made pursuant to any provision of this Section 5 shall have the net effect of increasing the Exercise Price
in relation to the split adjusted and distribution adjusted price of the Common Stock.


(e) Adjustments:
Additional Shares, Securities or Assets. In the event that at any time, as a result of an adjustment made pursuant to this
Section 5 or otherwise, Holder shall, upon Exercise of this Warrant, become entitled to receive shares and/or other securities
or assets (other than Common Stock) then, wherever appropriate, all references herein to shares of Common Stock shall be deemed
to refer to and include such shares and/or other securities or assets; and thereafter the number of such shares and/or other securities
or assets shall be subject to adjustment from time to time in a manner and upon terms as nearly equivalent as practicable to the
provisions of this Section 5.


(f) Notice
of Adjustments. Whenever the Exercise Price is adjusted pursuant to the terms of this Warrant, the Company shall promptly mail
to the Holder a notice (an “Exercise Price Adjustment Notice”) setting forth the Exercise Price after such adjustment
and setting forth a statement of the facts requiring such adjustment. The Company shall, upon the written request at any time of
the Holder, furnish to such Holder a like Warrant setting forth (i) such adjustment or readjustment, (ii) the Exercise
Price at the time in effect and (iii) the number of shares of Common Stock and the amount, if any, of other securities or
property which at the time would be received upon Exercise of the Warrant. For purposes of clarification, whether or not the Company
provides an Exercise Price Adjustment Notice pursuant to this Section 5(f), upon the occurrence of any event that leads to
an adjustment of the Exercise Price, the Holder would be entitled to receive a number of Exercise Shares based upon the new Exercise
Price, as adjusted, for exercises occurring on or after the date of such adjustment, regardless of whether the Holder accurately
refers to the adjusted Exercise Price in the Exercise Form.


6. Fractional
Interests.


No fractional shares or scrip representing fractional shares shall
be issuable upon the Exercise of this Warrant, but on Exercise of this Warrant, Holder may purchase only a whole number of shares
of Common Stock. If, on Exercise of this Warrant, Holder would be entitled to a fractional share of Common Stock or a right to
acquire a fractional share of Common Stock, such fractional share shall be disregarded and the number of shares of Common Stock
issuable upon Exercise shall be the next higher whole number of shares.



    	11



    	 



    

7. Reservation
of Shares.


From and after the date hereof, the Company shall at all times reserve
for issuance such number of authorized and unissued shares of Common Stock (or other securities substituted therefor as herein
above provided) as shall be sufficient for the Exercise of this Warrant and payment of the Exercise Price. If at any time the number
of shares of Common Stock authorized and reserved for issuance is below the number of shares sufficient for the Exercise of this
Warrant (a “Share Authorization Failure”) (based on the Exercise Price in effect from time to time), the Company will
promptly take all corporate action necessary to authorize and reserve a sufficient number of shares, including, without limitation,
calling a special meeting of stockholders to authorize additional shares to meet the Company’s obligations under this Section 7,
in the case of an insufficient number of authorized shares, and using its best efforts to obtain stockholder approval of an increase
in such authorized number of shares. The Company covenants and agrees that upon the Exercise of this Warrant, all shares of Common
Stock issuable upon such Exercise shall be duly and validly issued, fully paid and nonassessable and not subject to preemptive
rights, rights of first refusal or similar rights of any Person.


8. Restrictions
on Transfer.


(a) Registration
or Exemption Required. This Warrant has been issued in a transaction exempt from the registration requirements of the Securities
Act by virtue of Regulation D and exempt from state registration or qualification under applicable state laws. None of the Warrant,
the Exercise Shares or Failure Payment Shares may be pledged, transferred, sold or assigned except pursuant to an effective registration
statement or an exemption to the registration requirements of the Securities Act and applicable state laws including, without limitation,
a so-called “4(1) and a half” transaction.


(b) Assignment.
Subject to Section 8(a), the Holder may sell, transfer, assign, pledge, or otherwise dispose of this Warrant, in whole or
in part. Holder shall deliver a written notice to Company, substantially in the form of the Assignment attached hereto as Exhibit B,
indicating the Person or Persons to whom the Warrant shall be assigned and the respective number of warrants to be assigned to
each assignee. The Company shall effect the assignment within three (3) business days (the “Transfer Delivery Period”),
and shall deliver to the assignee(s) designated by Holder a Warrant or Warrants of like tenor and terms for the appropriate number
of shares. This Warrant and the rights evidenced hereby shall inure to the benefit of and be binding upon the successors and assigns
of the Holder. The provisions of this Warrant are intended to be for the benefit of all Holders from time to time of this Warrant,
and shall be enforceable by any such Holder. For avoidance of doubt, in the event Holder notifies the Company that such sale or
transfer is a so called “4(1) and half” transaction, the parties hereto agree that a legal opinion from outside counsel
for the Holder delivered to counsel for the Company substantially in the form attached hereto as Exhibit C shall be
the only requirement to satisfy an exemption from registration under the Securities Act to effectuate such “4(1) and half”
transaction.


9. Noncircumvention.


The Company hereby covenants and agrees that the Company will not,
by amendment of its certificate of incorporation, bylaws or through any reorganization, transfer of assets, consolidation, merger,
scheme of arrangement, dissolution, issue or sale of securities, or any other voluntary action, avoid or seek to avoid the observance
or performance of any of the terms of this Warrant, and will at all times in good faith carry out all the provisions of this Warrant
and take all action as may be reasonably required to protect the rights of the Holder. Without limiting the generality of the foregoing,
the Company (i) shall not increase the par value of any shares of Common Stock receivable upon the exercise of this Warrant
above the Exercise Price then in effect, and (ii) shall take all such actions as may be necessary or appropriate in order
that the Company may validly and legally issue fully paid and nonassessable shares of Common Stock upon the exercise of this Warrant.

10. Events
of Failure; Definition of Black Scholes Value.


(a) Definition. 


The occurrence of each of the following shall be considered to be
an “Event of Failure.”


(i) A Delivery Failure occurs, where a “Delivery Failure”
shall be deemed to have occurred if the Company fails to use its best efforts to deliver Exercise Shares to the Holder within any
applicable Delivery Period (other than due to the limitation contained in the proviso in the second paragraph of Section 1);


(ii) A Legend Removal Failure occurs, where a “Legend
Removal Failure” shall be deemed to have occurred if the Company fails to use its best efforts to issue this Warrant and/or
Exercise Shares without a restrictive legend, or fails to use it best efforts to remove a restrictive legend, when and as required
under Section 2(e) hereof;


(iii) a Transfer Delivery Failure occurs, where a “Transfer
Delivery Failure” shall be deemed to have occurred if the Company fails to use its best efforts to deliver a Warrant within
any applicable Transfer Delivery Period; and


(iv) a Registration Failure (as defined below).


For purpose hereof, “Registration Failure” means that
(A) the Company fails to file with the SEC on or before the Filing Deadline (as defined in the Registration Rights Agreement)
any Registration Statement required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, (B) the
Company fails to use its reasonable commercial efforts to obtain effectiveness with the SEC, prior to the Registration Deadline
(as defined in the Registration Rights Agreement), and if such Registration Statement is not so filed prior to the Registration
Deadline, as soon as possible thereafter, of any Registration Statement (as defined in the Registration Rights Agreement) that
are required to be filed pursuant to Section 2(a) of the Registration Rights Agreement, or fails to use reasonable commercial
efforts to keep such Registration Statement current and effective as required in Section 3 of the Registration Rights Agreement,
(C) The Company fails to file any additional Registration Statements required to be filed pursuant to Section 2(a)(ii) of the Registration
Rights Agreement on or before the Additional Filing Deadline or fails to use its reasonable commercial efforts to cause such new
Registration Statement to become effective on or before the Additional Registration Deadline, and if such effectiveness does not
occur within such period, as soon as possible thereafter, (D) the Company fails to file any amendment to any Registration
Statement, or any additional Registration Statement required to be filed pursuant to Section 3(b) of the Registration Rights
Agreement within twenty (20) days of the applicable Registration Trigger Date (as defined in the Registration Rights Agreement),
or fails to use its reasonable commercial efforts to cause such amendment and/or new Registration Statement to become effective
within sixty (60) days of the applicable Registration Trigger Date, and, if such effectiveness does not occur within such
period, as soon as possible thereafter, (E) any Registration Statement required to be filed under the Registration Rights
Agreement, after its initial effectiveness and during the Registration Period (as defined in the Registration Rights Agreement),
lapses in effect or sales of all of the Registrable Securities (as defined in the Registration Rights Agreement) cannot otherwise
be made thereunder (whether by reason of the Company’s failure to amend or supplement the prospectus included therein in
accordance with the Registration Rights Agreement, the Company’s failure to file and, use reasonable commercial efforts to
obtain effectiveness with the SEC of an additional Registration Statement or amended Registration Statement required pursuant to
Sections 2(a)(ii) or 3(b) of the Registration Rights Agreement, as applicable, or otherwise), and (F) the Company fails to
provide a commercially reasonable written response to any comments to any Registration Statement submitted by the SEC within twenty
(20) days of the date that such SEC comments are received by the Company.


(b) Failure Payments; Black-Scholes Determination. The Company
understands that any Event of Failure (as defined above) could result in economic loss to the Holder. In the event that any Event
of Failure occurs, as compensation to the Holder for such loss, the Company agrees to pay (as liquidated damages and not as a penalty)
to the Holder an amount (“Failure Payments”) payable, at the Company’s option, either (i) in cash or (ii) in
shares of Common Stock that are valued for these purposes at the Volume Weighted Average Price on the date of such calculation
(“Failure Payment Shares”), in each case equal to 15% per annum (or the maximum rate permitted by applicable law,
whichever is less) of the Black-Scholes value (as determined below) of the remaining unexercised portion of this Warrant on the
date of such Event of Failure (as recalculated on the first business day of each month thereafter for as long as Failure Payments
shall continue to accrue), which shall accrue daily from the date of such Event of Failure until the Event of Failure is cured,
accruing daily and compounded monthly, provided, however, the Holder shall only receive up to such amount of shares of Common Stock
in respect of Failure Payments such that Holder and any other persons or entities whose beneficial ownership of Common Stock would
be aggregated with the Holder’s for purposes of Section 13(d) of the Exchange Act (including shares held by any “group”
of which the Holder is a member, but excluding shares beneficially owned by virtue of the ownership of securities or rights to
acquire securities that have limitations on the right to convert, exercise or purchase similar to the limitation set forth herein)
shall not collectively beneficially own greater than 9.985% of the total number of shares of Common Stock of the Company then issued
and outstanding. For purposes of clarification, it is agreed and understood that Failure Payments shall continue to accrue following
any Event of Default until the applicable Default Amount is paid in full.

Notwithstanding the above, (1) in the event that the Company (i) has,
by the Filing Deadline (as defined the Registration Rights Agreement) filed a Registration Statement (as defined in the Registration
Rights Agreement) covering the number of shares required by the Registration Rights Agreement, and (ii) has responded in writing
to any comments to the Registration Statement that the Company has received from the SEC, within seven (7) Business Days of
such receipt, and nevertheless the SEC has not declared effective a Registration Statement covering the full number of Warrant
Shares issuable upon exercise of the Warrants by the Registration Deadline (as defined in the Registration Rights Agreement) then,
the Failure Payments attributable to such late Registration Effectiveness shall be reduced from 15% per annum to 12% (calculated
as set forth above) and (2) in no event shall the aggregate Failure Payments attributable solely to the failure by the SEC to declare
a Registration Statement effective exceed 10% of the Black-Scholes value of the Warrant. The Company shall satisfy any Failure
Payments under this Section pursuant to Section 10(c) below. Failure Payments are in addition to any Shares that the Holder is
entitled to receive upon Exercise of this Warrant.


For purposes hereof, the “Black-Scholes” value of a Warrant
shall be determined by use of the Black Scholes Option Pricing Model using the criteria set forth on Schedule 1 hereto.


(c) Payment of Accrued Failure Payments. The Failure Payment
Shares representing accrued Failure Payments for each Event of Failure shall be issued and delivered on or before the fifth (5th) business
day of each month following a month in which Failure Payments accrued and shall be the sole measure of damages for the Event of
Failure to which the Failure Payments relate. Nothing herein shall limit the Holder’s right to pursue a claim for specific
performance and/or injunctive relief. Notwithstanding the above, if a particular Event of Failure results in an Event of Default
pursuant to Section 11 hereof, then the Failure Payment, for that Event of Failure only, shall be considered to have been
satisfied upon payment to the Holder of an amount equal to the greater of (i) the Failure Payment, or (ii) the Default
Amount, payable in accordance with Section 11.


(d) Maximum Interest Rate. Nothing contained herein or in any
document referred to herein or delivered in connection herewith shall be deemed to establish or require the payment of a rate of
interest or other charges in excess of the maximum permitted by applicable law. In the event that the rate of interest or dividends
required to be paid or other charges hereunder exceed the maximum permitted by such law, any payments in excess of such maximum
shall be credited against amounts owed by the Company to the Holder and thus refunded to the Company.


 


11. Default.


(a) Events Of Default. Each of the following events shall
be considered to be an “Event of Default,” unless waived by the Holder:


(i) Failure
To Effect Registration. With respect to all Registration Failures, a Registration Failure occurs and remains uncured for a
period of more than forty-five (45) days (or sixty (60) days in the case where the Company (i) has, by the Filing Deadline
(as defined the Registration Rights Agreement) filed a Registration Statement (as defined in the Registration Rights Agreement)
covering the number of shares required by the Registration Rights Agreement, and (ii) has responded in writing to any comments
to the Registration Statement that the Company has received from the SEC, within seven (7) Business Days of such receipt,
and nevertheless the SEC has not declared effective a Registration Statement covering the Shares by the Registration Deadline (as
defined in the Registration Rights Agreement)), and such Registration Failure relates solely to the Company’s failure
to have the Registration Statement declared effective by the Registration Deadline (as defined in the Registration Rights Agreement)
and with respect to a Registration Failure provided in clause (E) of the definition of “Registration Failure”, such
Registration Failure occurs and remains uncured for a period of more than forty-five (45) days.



    	14



    	 



    

(ii) Failure
To Deliver Common Stock. A Delivery Failure (as defined above) occurs and remains uncured for a period of more than twenty
(20) days; or at any time, the Company announces or states in writing that it will not honor its obligations to issue shares of
Common Stock to the Holder upon Exercise by the Holder of the Exercise rights of the Holder in accordance with the terms of this
Warrant.


(iii) Legend
Removal Failure. A Legend Removal Failure (as defined above) occurs and remains uncured for a period of twenty (20) days; and


(iv) Corporate
Existence; Major Transaction. (A) The Company has failed to either (1) place the Major Transaction Warrant Early Termination
Price or the Exercise Shares issuable upon exercise of a Cashless Major Exercise, as the case may be, into escrow or (2) obtain
the written agreement of the Successor Entity as described in Section 5(c)(iv), or the Company has failed to instruct the escrow
agent to release such amount or such shares, as the case may be, to the Holder pursuant to Section 5(c)(iv), or (B) with respect
to a Major Transaction that is to be treated as an Assumption under the terms hereof, the Company has failed to meet the Assumption
requirements of Section 5(c)(ii).


(b) Mandatory
Early Termination.


(i) Mandatory
Early Termination Amount; Cashless Default Exercise. If any Events of Default shall occur then, unless waived by the Holder,
upon the occurrence and during the continuation of any Event of Default, at the option of the Holder, such option exercisable through
the delivery of written notice to the Company by such Holder (the “Default Notice”), the Company shall have the right
to terminate the outstanding amount of this Warrant and pay to the Holder (a “Mandatory Early Termination”), in full
satisfaction of its obligations hereunder by delivery of a notice to such effect to the Holder within two (2) Business Days following
receipt of the Default Notice, an amount payable in cash (the “Mandatory Early Termination Amount” or the “Default
Amount”) equal to the Black-Scholes value (as determined in accordance with Section 10(b)) of the remaining unexercised
portion of this Warrant on the date of such Default Notice. In the event the Company does not exercise its right to consummate
a Mandatory Early Termination, then the Holder shall have the right to exercise this Warrant pursuant to a Cashless Default Exercise
in accordance with Section 3(c) above.


The Mandatory Early Termination Amount shall be payable within five
(5) Business Days following the date of the applicable Default Notice.


(ii) Liquidated
Damages. The parties hereto acknowledge and agree that the sums payable as Failure Payments or pursuant to a Mandatory Early
Termination shall give rise to liquidated damages and not penalties. The parties further acknowledge that (i) the amount of
loss or damages likely to be incurred by the Holder is incapable or is difficult to precisely estimate, (ii) the amounts specified
bear a reasonable proportion and are not plainly or grossly disproportionate to the probable loss likely to be incurred by the
Holder, and (iii) the parties are sophisticated business parties and have been represented by sophisticated and able legal
and financial counsel and negotiated this Agreement at arm’s length.


(c) Posting
Of Bond. In the event that any Event of Default occurs hereunder, the Company may not raise as a legal defense (in any Lawsuit,
as defined below, or otherwise) or justification to such Event of Default any claim that such Holder or any one associated or affiliated
with such Holder has been engaged in any violation of law, unless the Company has posted a surety bond (a “Surety Bond”)
for the benefit of such Holder in the amount of 130% of the aggregate Surety Bond Value (as defined below) of all of the Holder’s
Warrants (the “Bond Amount”), which Surety Bond shall remain in effect until the completion of litigation of the dispute
and the proceeds of which shall be payable to such Holder to the extent Holder obtains judgment.



    	15



    	 



    

For purposes hereof, a “Lawsuit” shall mean any lawsuit,
arbitration or other dispute resolution filed by either party herein pertaining to any of this Warrant, the Facility Agreement
and the Registration Rights Agreement.


“Surety Bond Value,” for the Warrants shall mean 130%
of the of the Black-Scholes value of the remaining unexercised portion of this Warrant on the Trading Day immediately preceding
the date that such bond goes into effect).


(d) Remedies,
Other Obligations, Breaches And Injunctive Relief. The remedies provided in this Warrant shall be cumulative and in addition
to all other remedies available under this Warrant, the Facility Agreement and the Registration Rights Agreement, at law or in
equity (including a decree of specific performance and/or other injunctive relief), and nothing herein shall limit the right of
the Holder to pursue actual damages for any failure by the Company to comply with the terms of this Warrant. The Company acknowledges
that a breach by it of its obligations hereunder will cause irreparable harm to the Holder and that the remedy at law for any such
breach may be inadequate. The Company therefore agrees that, in the event of any such breach or threatened breach, the holder of
this Warrant shall be entitled, in addition to all other available remedies, to an injunction restraining any breach, without the
necessity of showing economic loss and without any bond or other security being required.


12. Holder’s
Early Terminations.


(a) Mechanics
of Holder’s Early Terminations. In the event that the Company does not deliver the applicable Major Transaction Warrant
Early Termination Price or Default Amount or the Exercise Shares in respect of a Cashless Major Exercise or a Cashless Default
Exercise, as the case may be, to the Holder within ten (10) days following the time period or as otherwise required pursuant to
the terms hereof, at any time thereafter the Holder shall have the option, upon notice to the Company, in lieu of early termination,
Cashless Major Exercise or Cashless Default Exercise, as the case may be, to require the Company to promptly return to the Holder
all or any portion of this Warrant that was submitted for early termination or exercise. Upon the Company’s receipt of such
notice, (x) the applicable early termination or exercise, as the case may be, shall be null and void with respect to such
applicable portion of this Warrant, (y) the Company shall immediately return this Warrant, or issue a new Warrant to the Holder
representing the portion of this Warrant that was submitted for early termination or exercise and (z) the Exercise Price of
this Warrant or such new Warrant shall be adjusted to the lesser of (A) the Exercise Price as in effect on the date on which the
applicable early termination, default or exercise notice, as the case may be, is voided and (B) the lowest closing price for the
Common Stock on NASDAQ, or, if NASDAQ is not the principal trading market for the Common Stock, the principal securities exchange
or other securities market on which the Common Stock is then being traded, during the period beginning on and including the date
on which the applicable early termination or exercise notice, as the case may be, is delivered to the Company and ending on and
including the date on which the applicable early termination or exercise is voided. The Holder’s delivery of a notice voiding
an early termination or exercise and exercise of its rights following such notice shall not affect the Company’s obligations
to make any payments of Failure Payments which have accrued prior to the date of such notice with respect to the Warrant subject
to such notice.


13. Benefits
of this Warrant.


Nothing in this Warrant shall be construed to confer upon any person
other than the Company and Holder any legal or equitable right, remedy or claim under this Warrant and this Warrant shall be for
the sole and exclusive benefit of the Company and Holder.

any provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party
for its reasonable attorneys’ fees and other costs and expenses incurred with the investigation, preparation and prosecution
of such action or proceeding.


15. Loss of
Warrant.


Upon receipt by the Company of evidence of the loss, theft, destruction
or mutilation of this Warrant, and (in the case of loss, theft or destruction) of indemnity or security reasonably satisfactory
to the Company, and upon surrender and cancellation of this Warrant, if mutilated, the Company shall execute and deliver a new
Warrant of like tenor and date.

Notwithstanding anything herein to the contrary, the maximum number
of shares of Common Stock issued or issuable pursuant to this Warrant and all additional Warrants issued pursuant to Section 2.10
of the Facility Agreement may not exceed the aggregate number of shares of Common Stock which the Company may issue upon exercise
