COMMON UNITS PURCHASE WARRANT 


SUMMIT SEMICONDUCTOR, LLC


 


	Warrant Units: [*]	 	 	Original Issue Date: [*]


 


 


THIS COMMON UNITPURCHASE WARRANT (the “Warrant”)
certifies that, for value received [*] or its assigns (the “Holder”) is entitled, upon the terms and subject
to the limitations on exercise and the conditions hereinafter set forth and in the Securities Purchase Agreement between the Company
and the Holder (the “Purchase Agreement”), at any time on or after the Original Issue Date and on or prior to
the close of business on the fifth anniversary of the Original Issue Date (the “Termination Date”) but not thereafter,
to subscribe for and purchase from Summit Semiconductor, LLC, a Delaware limited liability company (the “Company”),
up to [*] Common Units (as subject to adjustment hereunder, the “Warrant Units”); provided, however, the number
of Warrant Units exercisable pursuant to this Warrant shall double in the event the Company does not consummate an IPO by June
1, 2017. The purchase price of one Common Unit under this Warrant shall be equal to the Exercise Price, as defined in Section 2(b).


 


Section 1.               Definitions. Capitalized
terms used and not otherwise defined herein shall have the meanings set forth in the Senior Secured Original Issue Discount Convertible
Notes (the “Notes”), dated [*], issued by the Company to the purchasers pursuant to the Purchase Agreement.

Section 2.              Exercise.


 


a)            Exercise
of Warrant. Exercise of the purchase rights represented by this Warrant may be made, in whole or in part, at any time or times
on or after the Initial Exercise Date and on or before the Termination Date by delivery to the Company (or such other office or
agency of the Company as the Company may designate by notice in writing to the registered Holder at the address of the Holder appearing
on the books of the Company) of a duly executed facsimile copy of the Notice of Exercise form annexed hereto and within three (3)
Trading Days of the date said Notice of Exercise is delivered to the Company, the Company shall have received payment of the aggregate
Exercise Price of the Common Units thereby purchased by wire transfer to an account designated by the Company or cashier’s
check drawn on a United States bank or, if available, pursuant to the cashless exercise procedure specified in Section 2(c) below.
If the amount of payment received by the Company is less than the aggregate Exercise Price of the Common Units being purchased,
the Holder shall make payment of the deficiency within three (3) Trading Days following notice thereof. Notwithstanding anything
herein to the contrary, the Holder shall not be required to physically surrender this Warrant to the Company until the Holder has
purchased all of the Warrant Units available hereunder and the Warrant has been exercised in full, in which case, the Holder shall
surrender this Warrant to the Company for cancellation within three (3) Trading Days of the date the final Notice of Exercise is
delivered to the Company. Partial exercises of this Warrant resulting in purchases of a portion of the total number of Warrant
Units available hereunder shall automatically reduce the outstanding number of Warrant Units purchasable hereunder in an amount
equal to the applicable number of Warrant Units purchased. The Holder and the Company shall maintain records showing the number
of Warrant Units purchased and the date of such purchases. The Company shall deliver any objection to any Notice of Exercise Form
within two (2) Business Days of receipt of such notice. The Holder and any assignee, by acceptance of this Warrant, acknowledge
and agree that, by reason of the provisions of this paragraph, following the purchase of a portion of the Warrant Units hereunder,
the number of Warrant Units available for purchase hereunder at any given time may be less than the amount stated on the face hereof.


 


b)            Exercise
Price. The exercise price per Common Unit under this Warrant shall be $0.36 (the “Exercise Price”).


 


c)            Cashless
Exercise. In connection with a Cashless Exercise, this Warrant shall represent the right to subscribe for and acquire the number
of Warrant Units equal to (i) the number of Warrant Units specified by the Holder in its Notice of Exercise (the “Total
Number”) less (ii) the number of Warrant Units equal to the quotient obtained by dividing (A) the product of the Total
Number and the applicable existing Exercise Price by (B) the Fair Market Value. “Fair Market Value” shall mean:
(1) if the Warrant Units are listed on the NYSE MKT (formerly NYSE AMEX), the Nasdaq Capital Market, the Nasdaq Global Market,
the Nasdaq Global Select Market, the New York Stock Exchange, the OTC Bulletin Board or the Pink OTC Markets (or any successors
to any of the foregoing), the last reported sale price of the Warrant Units on such exchange or Nasdaq on the date for which the
determination is being made; or (2) if the Warrant Units are not so listed, “Fair Market Value” shall be determined
in good faith by the Board of Directors of the Company.


 


d)            Mechanics
of Exercise.


 


i.            Delivery
of Certificates Upon Exercise at IPO. If Holder exercises this Warrant in connection with the Company’s initial public
offering (the “IPO”), certificates for Common Units purchased hereunder shall be transmitted by the Transfer
Agent to the Holder by crediting the account of the Holder’s prime broker with The Depository Trust Company through its Deposit
or Withdrawal at Custodian system (“DWAC”) if the Company is then a participant in such system and either (A)
there is an effective registration statement permitting the issuance of the Warrant Units to or resale of the Warrant Units by
the Holder and such Warrant Units have been sold or (B) the Common Units are eligible for resale by the Holder without volume or
manner-of-sale limitations pursuant to Rule 144, and otherwise by physical delivery to the address specified by the Holder in the
Notice of Exercise by the date that is five (5) Trading Days after the latest of (A) the delivery to the Company of the Notice
of Exercise, (B) surrender of this Warrant (if required), and (C) payment of the aggregate Exercise Price as set forth above (including
by cashless exercise, if permitted) (such date, the “Warrant Unit Delivery Date”). The Warrant Units shall be
deemed to have been issued, and Holder or any other person so designated to be named therein shall be deemed to have become a holder
of record of such shares for all purposes, as of the date the Warrant has been exercised in accordance with the requirements of
the preceding sentence and with payment to the Company of the Exercise Price (or by cashless exercise, if permitted) and all taxes
required to be paid by the Holder, if any, pursuant to Section 2(d)(vi) prior to the issuance of such Common Units, having been
paid.


 




    	 	2	 



     


    

 


ii.         Delivery
of New Warrants Upon Exercise. If this Warrant shall have been exercised in part, the Company shall, at the request of a Holder
and upon surrender of this Warrant certificate, at the time of delivery of the certificate or certificates representing Warrant
Units, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unpurchased Warrant Units called
for by this Warrant, which new Warrant shall in all other respects be identical with this Warrant.


 


iii.         Rescission
Rights. If the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing
the Warrant Units pursuant to Section 2(d)(i) by the Warrant Unit Delivery Date, then the Holder will have the right to rescind
such exercise.


 


iv.         Compensation
for Buy-In on Failure to Timely Deliver Certificates Upon Exercise at IPO. In addition to any other rights available to the
Holder, if the Company fails to cause the Transfer Agent to transmit to the Holder a certificate or the certificates representing
the Warrant Units pursuant to an exercise on or before the Warrant Unit Delivery Date, 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,
Common Units to deliver in satisfaction of a sale by the Holder of the Warrant Units which the Holder anticipated receiving upon
such exercise (a “Buy-In”), then the Company shall (A) pay in cash to the Holder the amount, if any, by which
(x) the Holder’s total purchase price (including brokerage commissions, if any) for the Common Units so purchased exceeds
(y) the amount obtained by multiplying (1) the number of Warrant Units that the Company was required to deliver to the Holder in
connection with the exercise at issue times (2) the price at which the sell order giving rise to such purchase obligation was executed,
and (B) at the option of the Holder, either reinstate the portion of the Warrant and equivalent number of Warrant Units for which
such exercise was not honored (in which case such exercise shall be deemed rescinded) or deliver to the Holder the number of Common
Units that would have been issued had the Company timely complied with its exercise and delivery obligations hereunder subject
to payment of the Exercise Price therefor. For example, if the Holder purchases Common Units having a total purchase price of $11,000
to cover a Buy-In with respect to an attempted exercise of Common Units with an aggregate sale price giving rise to such purchase
obligation of $10,000, under clause (A) 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 and,
upon request of the Company, evidence of the amount of such loss. 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 Common Units upon exercise
of the Warrant as required pursuant to the terms hereof.


 




    	 	3	 



     


    

 


v.           No
Fractional Common Units. No fractional Common Units shall be issued upon the exercise of this Warrant. As to any fraction of
a Common Unit which the Holder would otherwise be entitled to purchase upon such exercise, the Company shall, at its election,
either pay a cash adjustment in respect of such final fraction in an amount equal to such fraction multiplied by the Exercise Price
or round to the nearest whole Common Unit.


 


Section 3.              Certain
Adjustments.


 


a)            Issuance
of Additional Common Units.


 


i.            Until
the Company consummates its IPO, in the event the Company shall issue any Additional Common Units (as defined below), at a price
per share less than the Exercise Price then in effect or without consideration, then the Exercise Price upon each such issuance
shall be adjusted to that price determined by multiplying the Exercise Price then in effect by a fraction:


 


(A)         the
numerator of which shall be equal to the sum of (x) the number of outstanding Common Units (assuming full exercise, conversion
or exchange of all warrants and other securities which are convertible into or exercisable or exchangeable for, and any right to
subscribe for, Common Units) immediately prior to the issuance of such Additional Common Units plus (y) the number of Common Units
(rounded to the nearest whole Common Unit) which the aggregate consideration for the total number of such Additional Common Units
so issued would purchase at a price per share equal to the Exercise Price then in effect, and


 


(B)         the
denominator of which shall be equal to the number of outstanding Common Units (assuming full exercise, conversion or exchange of
all warrants and other securities which are convertible into or exercisable or exchangeable for, and any right to subscribe for,
Common Units) immediately after the issuance of such Additional Common Units.


 


ii.         “Additional
Common Units” means all Common Units issued by the Company after the date hereof, except: (i) securities issued (other
than for cash) in connection with a merger, acquisition, or consolidation, (ii) securities issued pursuant to the conversion or
exercise of convertible or exercisable securities issued or outstanding on or prior to the date of the Purchase Agreement or issued
pursuant to the Purchase Agreement (so long as the conversion or exercise price in such securities are not amended to lower such
price and/or adversely affect the Holders), (iii) the Warrant Units, (iv) securities issued in connection with bona fide strategic
license agreements or other partnering arrangements so long as such issuances are not for the purpose of raising capital, (v) Common
Units issued to the Company’s employees, directors, consultants or advisors, and (vi) any warrants issued to any placement
agent and its designees for the transactions contemplated by the Purchase Agreement.


 




    	 	4	 



     


    

 


c)            Calculations.
All calculations under this Section 3 shall be made to the nearest cent or the nearest 1/100th of a Common Unit, as the case may
be. For purposes of this Section 3, the number of Common Units deemed to be issued and outstanding as of a given date shall be
the sum of the number of Common Units issued and outstanding.


 


d)            Notice
to Holder.


 


i.            Adjustment
to Exercise Price. Whenever the Exercise Price is adjusted pursuant to any provision of this Section 3, the Company shall promptly
mail to the Holder a notice setting forth the Exercise Price after such adjustment and any resulting adjustment to the number of
Warrant Units and setting forth a brief statement of the facts requiring such adjustment.


 


ii.         Notice
to Allow Exercise by Holder. If (A) the Company shall declare a dividend on the Common Units, (B) the Company shall declare
a special nonrecurring cash dividend on or a redemption of the Common Units, (C) the Company shall authorize the granting to all
holders of the Common Units rights or warrants to subscribe for or purchase any Common Units of any class or of any rights, (D)
the approval of any members of the Company shall be required in connection with any reclassification of the Common Units, any consolidation
or merger to which the Company is a party, any sale or transfer of all or substantially all of the assets of the Company, or any
compulsory share exchange whereby the Common Units are converted into other securities, cash or property, or (E) the Company shall
authorize the voluntary or involuntary dissolution, liquidation or winding up of the affairs of the Company, then, in each case,
the Company shall cause to be mailed to the Holder at its last address as it shall appear upon the Warrant Register of the Company,
at least 10 calendar days prior to the applicable record or effective date hereinafter specified, a notice stating (x) the date
on which a record is to be taken for the purpose of such dividend, redemption, rights or warrants, or if a record is not to be
taken, the date as of which the holders of the Common Units of record to be entitled to such dividend, redemption, rights or warrants
are to be determined or (y) the date on which such reclassification, consolidation, merger, sale, transfer or Common Unit exchange
is expected to become effective or close, and the date as of which it is expected that holders of the Common Units of record shall
be entitled to exchange their Common Units for securities, cash or other property deliverable upon such reclassification, consolidation,
merger, sale, transfer or Common Unit exchange; provided that the failure to mail such notice or any defect therein or in the mailing
thereof shall not affect the validity of the corporate action required to be specified in such notice. To the extent that any notice
provided hereunder constitutes, or contains, material, non-public information regarding the Company or any of the Subsidiaries,
the Company shall simultaneously publicly disclose such notice. The Holder shall remain entitled to exercise this Warrant during
the period commencing on the date of such notice to the effective date of the event triggering such notice except as may otherwise
be expressly set forth herein.


 


e)            Voluntary
Adjustment By Company. The Company may at any time during the term of this Warrant reduce the then current Exercise Price to
any amount and for any period of time deemed appropriate by the Board of Directors of the Company.


 




    	 	5	 



     


    

 


f)             Adjustment
for Number of Warrant Units. In the event that the Company is unable to include at least 25% of the Conversion Units in the
IPO registration, then the number of Warrant Units will be recalculated as follows:


 


New Number of Warrant Units = Principal Amount divided
by the Exercise Price.


 


Section 4.             Transfer
of Warrant.


 


a)           Transferability.
Subject to compliance with any applicable securities laws and the conditions set forth in Section 4(d) hereof, this Warrant and
all rights hereunder (including, without limitation, any registration rights) are transferable, in whole or in part, upon surrender
of this Warrant at the principal office of the Company or its designated agent, together with a written assignment of this Warrant
substantially in the form attached hereto duly executed by the Holder or its agent or attorney and funds sufficient to pay any
transfer taxes payable upon the making of such transfer, but only after such transferee agrees to be bound by the provisions of
this Agreement. Upon such surrender and, if required, such payment, the Company shall execute and deliver a new Warrant or Warrants
in the name of the assignee or assignees, as applicable, and in the denomination or denominations specified in such instrument
of assignment, and shall issue to the assignor a new Warrant evidencing the portion of this Warrant not so assigned, and this Warrant
shall promptly be cancelled. The Warrant, if properly assigned in accordance herewith, may be exercised by a new holder for the
purchase of Warrant Units without having a new Warrant issued.


 


b)            New
Warrants. This Warrant may be divided or combined with other Warrants upon presentation hereof at the aforesaid office of the
Company, together with a written notice specifying the names and denominations in which new Warrants are to be issued, signed by
the Holder or its agent or attorney. Subject to compliance with Section 4(a), as to any transfer which may be involved in such
division or combination, the Company shall execute and deliver a new Warrant or Warrants in exchange for the Warrant or Warrants
to be divided or combined in accordance with such notice. All Warrants issued on transfers or exchanges shall be dated the Original
Issue Date and shall be identical with this Warrant except as to the number of Warrant Units issuable pursuant thereto.


 


c)            Warrant
Register. The Company shall register this Warrant, upon records to be maintained by the Company for that purpose (the “Warrant
Register”), in the name of the record Holder hereof from time to time. The Company may deem and treat the registered
Holder of this Warrant as the absolute owner hereof for the purpose of any exercise hereof or any distribution to the Holder, and
for all other purposes, absent actual notice to the contrary.


 


d)           Transfer
Restrictions. The Warrant may only be disposed of in compliance with state and federal securities laws and shall not transferred
unless the Warrant is (i) registered pursuant to an effective registration statement under the Securities Act and under applicable
state securities or blue sky laws or (ii) eligible for resale without volume or manner-of-sale restrictions or current public information
requirements pursuant to Rule 144.


 




    	 	6	 



     


    

 


e)             Representation
by the Holder. The Holder, by the acceptance hereof, represents and warrants that it is acquiring this Warrant and, upon any
exercise hereof, will acquire the Warrant Units issuable upon such exercise, for its own account and not with a view to or for
distributing or reselling such Warrant Units or any part thereof in violation of the Securities Act or any applicable state securities
law, except pursuant to sales registered or exempted under the Securities Act.


 


Section 5.               Miscellaneous.


 


a)             No
Rights as Member Until Exercise. This Warrant does not entitle the Holder to any voting rights or other rights as a member
of the Company prior to the exercise hereof as set forth in Section 2(d)(i), except as expressly set forth in Section 3.


 


b)            Loss,
Theft, Destruction or Mutilation of Warrant. The Company covenants that upon receipt by the Company of evidence reasonably
satisfactory to it of the loss, theft, destruction or mutilation of this Warrant or any stock certificate relating to the Warrant
Units, and in case of loss, theft or destruction, of indemnity or security reasonably satisfactory to it (which, in the case of
the Warrant, shall not include the posting of any bond), and upon surrender and cancellation of such Warrant or stock certificate,
if mutilated, the Company will make and deliver a new Warrant or stock certificate of like tenor and dated as of such cancellation,
in lieu of such Warrant or stock certificate.


 


c)            Saturdays,
Sundays, Holidays, etc. If the last or appointed day for the taking of any action or the expiration of any right required or
granted herein shall not be a Business Day, then, such action may be taken or such right may be exercised on the next succeeding
Business Day.


 


d)            Authorized
Common Units.


 


The Company will
take all such reasonable action as may be necessary to assure that such Warrant Units may be issued as provided herein without
violation of any applicable law or regulation, or of any requirements of the Trading Market upon which the Common Units may be
listed. The Company covenants that all Warrant Units which may be issued upon the exercise of the purchase rights represented by
this Warrant will, upon exercise of the purchase rights represented by this Warrant and payment for such Warrant Units in accordance
herewith, be duly authorized, validly issued, fully paid and nonassessable and free from all taxes, liens and charges created by
the Company in respect of the issue thereof (other than taxes in respect of any transfer occurring contemporaneously with such
issue).


 


Except and to the
extent as waived or consented to by the Holder, the Company shall not by any action, including, without limitation, amending its
Operating Agreement or through any reorganization, transfer of assets, consolidation, merger, 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, but will
at all times in good faith assist in the carrying out of all such terms and in the taking of all such actions as may be necessary
or appropriate to protect the rights of Holder as set forth in this Warrant against impairment. Without limiting the generality
of the foregoing, the Company will (i) take all such action as may be necessary or appropriate in order that the Company may validly
and legally issue fully paid and nonassessable Warrant Units upon the exercise of this Warrant and (ii) use commercially reasonable
efforts to obtain all such authorizations, exemptions or consents from any public regulatory body having jurisdiction thereof,
as may be, necessary to enable the Company to perform its obligations under this Warrant.


 




    	 	7	 



     


    

 


Before taking any
action which would result in an adjustment in the number of Warrant Units for which this Warrant is exercisable or in the Exercise
Price, the Company shall obtain all such authorizations or exemptions thereof, or consents thereto, as may be necessary from any
public regulatory body having jurisdiction thereof.


 


e)            Jurisdiction.
All questions concerning the construction, validity, enforcement and interpretation of the Transaction Documents 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.


 


f)             Restrictions.
The Holder acknowledges that the Warrant Units acquired upon the exercise of this Warrant, if not registered and the Holder does
not utilize cashless exercise, will have restrictions upon resale imposed by state and federal securities laws.


 


g)            Nonwaiver
and Expenses. No course of dealing or any delay or failure to exercise any right hereunder on the part of Holder or Company
shall operate as a waiver of such right or otherwise prejudice the Holder’s or Company’s rights, powers or remedies,
notwithstanding the fact that all rights hereunder terminate on the Termination Date. If either party willfully and knowingly fails
to comply with any provision of this Warrant, which results in any material damages to the other, the first party shall pay to
the other party such amounts as shall be sufficient to cover any costs and expenses including, but not limited to, reasonable attorneys’
fees, including those of appellate proceedings, incurred by the affected party in collecting any amounts due pursuant hereto or
in otherwise enforcing any of its rights, powers or remedies hereunder.


 


h)            Notices.
Any and all notices or other communications or deliveries required or permitted to be provided hereunder shall be in writing and
shall be deemed given and effective on the earliest of: (a) the date of transmission, if such notice or communication is delivered
via email or facsimile at the email address or facsimile number set forth on the signature pages attached to the Purchase Agreement
at or prior to 5:30 p.m. (New York City time) on a Trading Day, (b) the next Trading Day after the date of email or facsimile transmission,
if such notice or communication is delivered via email or facsimile at the email address or facsimile number set forth on the signature
pages attached to the Purchase Agreement on a day that is not a Trading Day or later than 5:30 p.m. (New York City time) on any
Trading Day, (c) the second (2nd) Trading Day following the date of mailing, if sent by U.S. nationally recognized overnight courier
service or (d) upon actual receipt by the party to whom such notice is required to be given. The address for such notices and communications
shall be as set forth on the signature page attached to the Purchase Agreement.


 


i)             Limitation
of Liability. No provision hereof, in the absence of any affirmative action by the Holder to exercise this Warrant to purchase
Warrant Units, and no enumeration herein of the rights or privileges of the Holder, shall give rise to any liability of the Holder
for the purchase price of any Common Units or as a member of the Company, whether such liability is asserted by the Company or
by creditors of the Company.


 




    	 	8	 



     


    

 


j)             Remedies.
The Holder, in addition to being entitled to exercise all rights granted by law, including recovery of damages, will be entitled
to specific performance of its rights under this Warrant. The Company agrees that monetary damages would not be adequate compensation
for any loss incurred by reason of a breach by it of the provisions of this Warrant and hereby agrees to waive and not to assert
the defense in any action for specific performance that a remedy at law would be adequate.


 


k)            Successors
and Assigns. Subject to applicable securities laws, this Warrant and the rights and obligations evidenced hereby shall inure
to the benefit of and be binding upon the successors and permitted assigns of the Company and the successors and permitted assigns
of Holder. The provisions of this Warrant are intended to be for the benefit of any Holder from time to time of this Warrant and
shall be enforceable by the Holder or holder of Warrant Units.


 


l)             Amendment.
This Warrant may be modified or amended or the provisions hereof waived in accordance with the Purchase Agreement. Holder acknowledges
and agrees that this Warrant is subject to the Operating Agreement.


 


m)            Severability.
Wherever possible, each provision of this Warrant shall be interpreted in such manner as to be effective and valid under applicable
law, but if any provision of this Warrant shall be prohibited by or invalid under applicable law, such provision shall be ineffective
to the extent of such prohibition or invalidity, without invalidating the remainder of such provisions or the remaining provisions
of this Warrant.


 


n)            Headings.
The headings used in this Warrant are for the convenience of reference only and shall not, for any purpose, be deemed a part of
this Warrant.
