              DURATION
      AND EXERCISE OF WARRANTS

            


    

    


    (a)           Exercise
Period.  The Holder may exercise this Warrant in whole or in
part on any Business Day on or before 5:00 P.M., Eastern Time, on the Expiration
Date, at which time this Warrant shall become void and of no value.

    


    
      	
               
      

            	
              (b)

            	
              Exercise
      Procedures.

            


    

    


    (i)           While
this Warrant remains outstanding and exercisable in accordance with Section
1(a), in addition to the manner set forth in Section 1(b)(ii) below, the Holder
may exercise this Warrant in whole or in part at any time and from time to time
by:

    


    (A)           delivery
to the Company of a duly executed copy of the Notice of Exercise attached as
Exhibit A;

    


    (B)           surrender
of this Warrant to the Secretary of the Company at its principal offices or at
such other office or agency as the Company may specify in writing to the Holder;
and

    


    (C)           payment
of the then-applicable Exercise Price per share multiplied by the number of
Warrant Shares being purchased upon exercise of the Warrant (such amount, the
“Aggregate Exercise
Price”) made in the form of cash, or by certified check, bank draft or
money order payable in lawful money of the United States of America or in the
form of a Cashless Exercise to the extent permitted in Section 1(b)(ii)
below.

    


    (ii)           In
addition to the provisions of Section 1(b)(i) above, if any time after the first
anniversary of the date of the filing of the Current Report on Form 8-K
reporting the reverse merger (the “Merger”) of InVivo Therapeutics Corporation,
and a wholly owned subsidiary of the Company, a registration statement
covering the resale of the Warrant Shares by the Holder is not effective with
the Securities and Exchange Commission (the “SEC”), the Holder may, in its
sole discretion, exercise all or any part of the Warrant in a “cashless” or
“net-issue” exercise (a “Cashless Exercise”) by
delivering to the Company (1) the Notice of Exercise and (2) the original
Warrant, pursuant to which the Holder shall surrender the right to receive upon
exercise of this Warrant, a number of Warrant Shares having a value (as
determined below) equal to the Aggregate Exercise Price, in which case, the
number of Warrant Shares to be issued to the Holder upon such exercise shall be
calculated using the following formula:


    
      
         


      

      
        2

        
          

        

      

      
         


      

    

    


    X           =              Y * (A -
B)

      
   A

    


    with:        
  X
=           the number of
Warrant Shares to be issued to the Holder

    


    
      	
               
      

            	
              Y
      =

            	
              the
      number of Warrant Shares with respect to which the Warrant is being
      exercised

            


    

    


    
      	
               
      

            	
              A
      =

            	
              the
      fair value per share of Common Stock on the date of exercise of this
      Warrant

            


    

    


    B
=            the
then-current Exercise Price of the Warrant

    


    Solely
for the purposes of this paragraph, “fair value” per share of
Common Stock shall mean the average Closing Price (as defined below) per share
of Common Stock for the twenty (20) trading days immediately preceding the date
on which the Notice of Exercise is deemed to have been sent to the
Company.  “Closing
Price” means, for any date, the price determined by the first of the
following clauses that applies:  (a) if the Common Stock is then
listed or quoted on the New York Stock Exchange, the American Stock Exchange,
the NASDAQ Global Select Market, the NASDAQ Global Market or the NASDAQ Capital
Market or any other national securities exchange, the closing price per
share of the Common Stock for such date (or the nearest preceding date) on the
primary eligible market or exchange on which the Common Stock is then listed or
quoted; (b) if prices for the Common Stock are then quoted on the OTC Bulletin
Board, the closing bid price per share of the Common Stock for such date (or the
nearest preceding date) so quoted; or (c) if prices for the Common Stock are
then reported in the “Pink Sheets” published by the National Quotation
Bureau Incorporated (or a similar organization or agency succeeding to its
functions of reporting prices), the most recent closing bid price per share of
the Common Stock so reported.  If the Common Stock is not publicly
traded as set forth above, the “fair value” per share of Common Stock shall be
reasonably and in good faith determined by the Board of Directors of the Company
as of the date which the Notice of Exercise is deemed to have been sent to the
Company.

    


    Notwithstanding
the foregoing, provided that a registration statement covering the resale of the
Warrant Shares by the Holder has (x) been declared effective by the SEC and
(y) remained effective for a period of one year, any Cashless Exercise right
hereunder shall thereupon terminate.

    


    For purposes of Rule 144 promulgated
under the Securities Act, it is intended, understood and acknowledged that the
Warrant Shares issued in a cashless exercise transaction shall be deemed to have
been acquired by the Holder, and the holding period for such shares shall be
deemed to have commenced, on the date this Warrant was originally
issued.

    (iii)           Upon
the exercise of this Warrant in compliance with the provisions of this Section
1(b), and except as limited pursuant to the last paragraph of Section 1(b)(ii),
the Company shall promptly issue and cause to be delivered to the Holder a
certificate for the Warrant Shares purchased by the Holder.  Each
exercise of this Warrant shall be effective immediately prior to the close of
business on the date (the “Date
of Exercise”) that the conditions set forth in Section 1(b) have been
satisfied, as the case may be.  On the first Business Day following
the date on which the Company has received each of the Notice of Exercise and
the Aggregate Exercise Price (or notice of a Cashless Exercise in accordance
with Section 1(b)(ii)) (the “Exercise Delivery Documents”),
the Company shall transmit an acknowledgment of receipt of the Exercise Delivery
Documents to the Company’s transfer agent (the “Transfer Agent”). On or before the third
Business Day following the date on which the Company has received all of the
Exercise Delivery Documents (the “Share Delivery Date”), the
Company shall (X) provided that the Transfer Agent is participating in The
Depository Trust Company (“DTC”) Fast Automated
Securities Transfer Program, upon the request of the Holder, credit such
aggregate number of shares of Common Stock to which the Holder is entitled
pursuant to such exercise to the Holder’s or its designee’s balance account with
DTC through its Deposit Withdrawal Agent Commission system, or (Y) if the
Transfer Agent is not participating in the DTC Fast Automated Securities
Transfer Program, issue and dispatch by overnight courier to the address as
specified in the Notice of Exercise, a certificate, registered in the Company’s
share register in the name of the Holder or its designee, for the number of
shares of Common Stock to which the Holder is entitled pursuant to such
exercise.  Upon delivery of the Exercise Delivery Documents, 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 of delivery of the certificates evidencing
such Warrant Shares.

    


    (iv)           If
the Company shall fail for any reason or for no reason to issue to the Holder,
within three (3) Business Days of receipt of the Exercise Delivery Documents, a
certificate for the number of shares of Common Stock to which the Holder is
entitled and register such shares of Common Stock on the Company’s share
register or to credit the Holder’s balance account with DTC for such number of
shares of Common Stock to which the Holder is entitled upon the Holder’s
exercise of this Warrant, and if on or after such Business Day the Holder
purchases (in an open market transaction or otherwise) shares of Common Stock to
deliver in satisfaction of a sale by the Holder of shares of Common Stock
issuable upon such exercise that the Holder anticipated receiving from the
Company (a “Buy-In”),
then the Company shall, within three (3) Business Days after the Holder’s
request and in the Holder’s discretion, either (i) pay cash to the Holder in an
amount equal to the Holder’s total purchase price (including brokerage
commissions, if any) for the shares of Common Stock so purchased (the “Buy-In Price”), at which point
the Company’s obligation to deliver such certificate (and to issue such shares
of Common Stock) shall terminate, or (ii) promptly honor its obligation to
deliver to the Holder a certificate or certificates representing such shares of
Common Stock and pay cash to the Holder in an amount equal to the excess (if
any) of the Buy-In Price over the product of (A) such number of shares of Common
Stock, times (B) the closing bid price on the date of
exercise.

    


    (c)           Partial
Exercise.  This Warrant shall be exercisable, either in its
entirety or, from time to time, for part only of the number of Warrant Shares
referenced by this Warrant. If this Warrant is submitted in connection with any
exercise pursuant to Section 1 and the number of Warrant Shares represented by
this Warrant submitted for exercise is greater than the actual number of Warrant
Shares being acquired upon such an exercise, then the
Company shall as soon as practicable and in no event later than five (5)
Business Days after any exercise and at its own expense, issue a new Warrant of
like tenor representing the right to purchase the number of Warrant Shares
purchasable immediately prior to such exercise under this Warrant, less the
number of Warrant Shares with respect to which this Warrant is
exercised.

    (d)           Disputes.  In
the case of a dispute as to the determination of the Exercise Price or the
arithmetic calculation of the Warrant Shares, the Company shall promptly issue
to the Holder the number of Warrant Shares that are not disputed and resolve
such dispute in accordance with Section 16.

              ISSUANCE
      OF WARRANT SHARES

            


    

    


    (a)           The
Company covenants that all Warrant Shares will, upon issuance in accordance with
the terms of this Warrant, be (i) duly authorized, fully paid and
non-assessable, and (ii) free from all liens, charges and security interests,
with the exception of claims arising through the acts or omissions of any Holder
and except as arising from applicable Federal and state securities
laws.

    


    (b)           The
Company shall register this Warrant upon records to be maintained by the Company
for that purpose in the name of the record holder of such Warrant from time to
time. The Company may deem and treat the registered Holder of this Warrant as
the absolute owner thereof for the purpose of any exercise thereof, any
distribution to the Holder thereof and for all other purposes.

    


    (c)           The
Company will not, by amendment of its certificate of incorporation, by-laws 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 to be observed
or performed hereunder by the Company, but will at all times in good faith
assist in the carrying out of all the provisions of this Warrant and in the
taking of all action necessary or appropriate in order to protect the rights of
the Holder to exercise this Warrant, or against impairment of such
rights.

              ADJUSTMENTS
      OF EXERCISE PRICE, NUMBER AND TYPE OF WARRANT
  SHARES

            


    

    


    (a)           The
Exercise Price and the number of shares purchasable upon the exercise of this
Warrant shall be subject to adjustment from time to time upon the occurrence of
certain events described in this Section 3; provided, that
notwithstanding the provisions of this Section 3, the Company shall not be
required to make any adjustment if and to the extent that such adjustment would
require the Company to issue a number of shares of Common Stock in excess of its
authorized but unissued shares of Common Stock, less all amounts of Common Stock
that have been reserved for issue upon the conversion of all outstanding
securities convertible into shares of Common Stock and the exercise of all
outstanding options, warrants and other rights exercisable for shares of Common
Stock.  If the Company does not have the requisite number of
authorized but unissued shares of Common Stock to make any adjustment, the
Company shall use its commercially best efforts to obtain the necessary
stockholder consent to increase the authorized number of shares of Common Stock
to make such an adjustment pursuant to this Section 3.


    
      
         


      

      
        5

        
          

        

      

      
         


      

    

     

    (i)           Subdivision or Combination
of Stock. In case the Company shall at any time subdivide (whether by way
of stock dividend, stock split or otherwise) its outstanding shares of Common
Stock into a greater number of shares, the Exercise Price in effect immediately
prior to such subdivision shall be proportionately reduced and the number of
Warrant Shares shall be proportionately increased, and conversely, in case the
outstanding shares of Common Stock of the Company shall be combined (whether by
way of stock combination, reverse stock split or otherwise) into a smaller
number of shares, the Exercise Price in effect immediately prior to such
combination shall be proportionately increased and the number of Warrant Shares
shall be proportionately decreased.  The Exercise Price and the
Warrant Shares, as so adjusted, shall be readjusted in the same manner upon
the happening of any successive event or events described in this Section
3(a)(i).

    


    (ii)           Dividends in Stock,
Property, Reclassification. If at any time, or from time to time, all of
the holders of Common Stock (or any shares of stock or other securities at the
time receivable upon the exercise of this Warrant) shall have received or become
entitled to  receive, without payment therefore:

    


    (A)           any
shares of stock or other securities that are at any time directly or indirectly
convertible into or exchangeable for Common Stock, or any rights or options to
subscribe for, purchase or otherwise acquire any of the foregoing by way of
dividend or other distribution, or

    


    (B)           additional
stock or other securities or property (including cash) by way of spin-off,
split-up, reclassification, combination of shares or similar corporate
rearrangement (other than shares of Common Stock issued as a stock split or
adjustments in respect of which shall be covered by the terms of Section 3(a)(i)
above),

    


    then and
in each such case, the Exercise Price and the number of Warrant Shares to be
obtained upon exercise of this Warrant shall be adjusted proportionately, and
the Holder hereof shall, upon the exercise of this Warrant, be entitled to
receive, in addition to the number of shares of Common Stock receivable
thereupon, and without payment of any additional consideration therefor, the
amount of stock and other securities and property (including cash in the cases
referred to above) that such Holder would hold on the date of such exercise had
such Holder been the holder of record of such Common Stock as of the date on
which holders of Common Stock received or became entitled to receive such shares
or all other additional stock and other securities and
property.  The Exercise Price and the Warrant Shares, as so adjusted,
shall be readjusted in the same manner upon the happening of any successive
event or events described in this Section 3(a)(ii).

     

    
      
         


      

      
        6

        
          

        

      

      
         


      

    


    (iii)           Reorganization,
Reclassification, Consolidation, Merger or
Sale. If any
recapitalization, reclassification or reorganization of the capital stock of the
Company, or any consolidation or merger of the Company with another corporation,
or the sale of all or substantially all of its assets or other
transaction shall be
effected in such a way that holders of Common Stock shall be entitled to receive
stock, securities, or other assets or property (an “Organic
Change”), then, as a condition of such Organic
Change, lawful and adequate provisions shall be made by the Company whereby the Holder
hereof shall thereafter have the right to purchase and receive (in lieu of the
shares of the Common Stock of the Company immediately theretofore purchasable
and receivable upon the exercise of the rights represented by this Warrant) such shares of stock,
securities or other assets or property as may be issued or payable with respect
to or in exchange for a number of outstanding shares of such Common Stock equal
to the number of shares of such stock immediately theretofore purchasable and receivable assuming the
full exercise of the rights represented by this Warrant. In the event of any
Organic Change, appropriate provision shall be made by the Company with respect
to the rights and interests of the Holder of this Warrant to the end that the provisions hereof
(including, without limitation, provisions for adjustments of the Exercise Price
and of the number of shares purchasable and receivable upon the exercise of this
Warrant and registration rights) shall thereafter be applicable, in relation to any shares of
stock, securities or assets thereafter deliverable upon the exercise hereof. The
Company will not effect any such consolidation, merger or sale unless, prior to
the consummation thereof, the successor corporation (if other than the Company) resulting from
such consolidation or merger or the corporation purchasing such assets shall
assume by written instrument reasonably satisfactory in form and substance to
the Holder executed and mailed or delivered to the registered Holder hereof at the last address of such
Holder appearing on the books of the Company, the obligation to deliver to such
Holder such shares of stock, securities or assets as, in accordance with the
foregoing provisions, such Holder may be entitled to purchase. If there is an Organic Change, then the
Company shall cause to be mailed to the Holder at its last address as it shall
appear on the books and records of the Company, at least 10 calendar days before
the effective date of the Organic Change, a notice stating the date on which such Organic
Change is expected to become effective or close, and the date as of which it is
expected that holders of the Common Stock of record shall be entitled to
exchange their shares for securities, cash, or other property delivered upon such Organic Change;
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.  The Holder is entitled to
exercise this Warrant during the 10-day
period commencing on the date of such notice to the effective date of the event
triggering such notice. In any event, the successor corporation
(if other than the Company) resulting from such consolidation or merger or
the corporation purchasing
such assets shall be deemed to assume such obligation to deliver to such Holder
such shares of stock, securities or assets even in the absence of a written
instrument assuming such obligation to the extent such assumption occurs
by operation of law.

    


    (b)           Certificate as to
Adjustments. Upon the occurrence of each adjustment or readjustment
pursuant to this Section 3, the Company at its expense shall promptly compute
such adjustment or readjustment in accordance with the terms hereof and furnish
to each Holder of this Warrant a certificate setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Company shall promptly furnish or cause to be
furnished to such Holder a like certificate setting forth: (i) such adjustments
and readjustments; and (ii) the number of shares and the amount, if any, of
other property which at the time would be received upon the exercise of the
Warrant.

    (c)           Certain Events. If
any event occurs as to which the other provisions of this Section 3 are not
strictly applicable but the lack of any adjustment would not fairly protect the
purchase rights of the Holder under this Warrant in accordance with the basic
intent and principles of such provisions, or if strictly applicable would not
fairly protect the purchase rights of the Holder under this Warrant in
accordance with the basic intent and principles of such provisions, then the
Company's Board of Directors will, in good faith, make an appropriate adjustment
to protect the rights of the Holder; provided, that no
such adjustment pursuant to this Section 3(c) will increase the Exercise Price
or decrease the number of Warrant Shares as otherwise determined pursuant to
this Section 3.

    


    (d)           Adjustment of Exercise Price
Upon Issuance of Additional Shares of Common Stock.  In the
event the Company shall at any time prior to the Expiration Date issue
Additional Shares of Common Stock, as defined below, without consideration or
for a consideration per share less than the Exercise Price in effect immediately
prior to such issue, then the Exercise Price shall be reduced, concurrently with
such issue, to a price (calculated to the nearest cent) determined by
multiplying such Exercise Price by a fraction, (A) the numerator of which shall
be (1) the number of shares of Common Stock outstanding immediately prior to
such issue plus (2) the number of shares of Common Stock which the aggregate
consideration received or to be received by the Company for the total number of
Additional Shares of Common Stock so issued would purchase at such Exercise
Price; and (B) the denominator of which shall be the number of shares of Common
Stock outstanding immediately prior to such issue plus the number of such
Additional Shares of Common Stock so issued; provided that, (i)
for the purpose of this Section 3(d), all shares of Common Stock issuable upon
conversion or exchange of convertible securities outstanding immediately prior
to such issue shall be deemed to be outstanding, and (ii) the number of shares
of Common Stock deemed issuable upon conversion or exchange of such outstanding
convertible securities shall be determined without giving effect to any
adjustments to the conversion or exchange price or conversion or exchange rate
of such convertible securities resulting from the issuance of Additional Shares
of Common Stock that is the subject of this calculation.  For purposes
of this Warrant, “Additional Shares of Common Stock” shall mean all shares of
Common Stock issued by the Company after the Effective Date (including without
limitation any shares of Common Stock issuable upon conversion or exchange of
any convertible securities or upon exercise of any option or warrant, on an
as-converted basis), other than: (i) shares of Common Stock issued or
issuable upon conversion or exchange of any convertible securities or exercise
of any options or warrants outstanding on the Effective Date; (ii) shares
of Common Stock issued or issuable by reason of a dividend, stock split,
split-up or other distribution on shares of Common Stock that is covered by
Sections 3(a)(i) through 3(a)(iii) above; (iii) shares of Common Stock (or
options with respect thereto) issued or issuable to employees or directors of,
or consultants to, the Company or any of its subsidiaries pursuant to a plan,
agreement or arrangement approved by the Board of Directors of the Company; (iv)
any securities issued or issuable by the Company pursuant to (A) the Company’s
private offering (the “Offering”) of securities pursuant to a Private
Placement  Memorandum, dated as of October 4, 2010 (the “Memorandum”)
and the related Subscription Agreements (the “Subscription Agreement”)
thereunder, (B) the Merger or (C) the transactions contemplated by the
Memorandum and the Merger; (v) securities issued pursuant to acquisitions or
strategic transactions approved by a majority of disinterested directors of the
Company, provided that any such issuance shall only be to a person which is,
itself or through its subsidiaries, an operating company in a business
synergistic with the business of the Company and in which the Company receives
benefits in addition to the investment of funds, but shall not include a
transaction in which the Company is issuing securities primarily for the purpose
of raising capital or to an entity whose primary business is investing in
securities and (vi) securities issued to financial institutions, institutional
investors or lessors in connection with credit arrangements, equipment

upon exercise of this Warrant immediately prior to such adjustment and dividing
the product so obtained by the adjusted Exercise Price.

SHARES

            


    

    


    (a)           Registration of Transfers
and Exchanges. Subject to Section 4(c), upon the Holder’s surrender of
this Warrant, with a duly executed copy of the Form of Assignment attached as
Exhibit B, to the
Secretary of the Company at its principal offices or at such other office or
agency as the Company may specify in writing to the Holder, the Company shall
register the transfer of all or any portion of this Warrant. Upon such
registration of transfer, the Company shall issue a new Warrant, in
substantially the form of this Warrant, evidencing the acquisition rights
transferred to the transferee and a new Warrant, in similar form, evidencing the
remaining acquisition rights not transferred, to the Holder requesting the
transfer.

    


    (b)           Warrant Exchangeable for
Different Denominations. The Holder may exchange this Warrant for a new
Warrant or Warrants, in substantially the form of this Warrant, evidencing in
the aggregate the right to purchase the number of Warrant Shares which may then
be purchased hereunder, each of such new Warrants to be dated the date of such
exchange and to represent the right to purchase such number of Warrant Shares as
shall be designated by the Holder. The Holder shall surrender this Warrant with
duly executed instructions regarding such re-certification of this Warrant to
the Secretary of the Company at its principal offices or at such other office or
agency as the Company may specify in writing to the Holder.

    


    (c)           Restrictions on
Transfers. This Warrant may not be transferred at any time without (i)
registration under the Securities Act or (ii) an exemption from such
registration and a written opinion of legal counsel addressed to the Company
that the proposed transfer of the Warrant may be effected without registration
under the Securities Act, which opinion will be in form and from counsel
reasonably satisfactory to the Company.

    


    (d)           Permitted Transfers and
Assignments.  Notwithstanding any provision to the contrary in
this Section 4, the Holder may transfer, with or without consideration, this
Warrant or any of the Warrant Shares (or a portion thereof) to the Holder’s
Affiliates (as such term is defined under Rule 144 of the Securities Act)
without obtaining the opinion from counsel that may be required by Section
4(c)(ii), provided, that the
Holder delivers to the Company and its counsel certification, documentation, and
other assurances reasonably required by the Company’s counsel to enable the
Company’s counsel to render an opinion to the Company’s Transfer Agent that such
transfer does not violate applicable securities laws.

    If this Warrant is mutilated, lost,
stolen or destroyed, upon request by the Holder, the Company will, at its
expense, issue, in exchange for and upon cancellation of the mutilated Warrant,
or in substitution for the lost, stolen or destroyed Warrant, a new Warrant, in
substantially the form of this Warrant, representing the right to acquire the
equivalent number of Warrant Shares; provided, that, as a
prerequisite to the issuance of a substitute Warrant, the Company may require
satisfactory evidence of loss, theft or destruction as well as an indemnity from
the Holder of a lost, stolen or destroyed Warrant.

Warrant, or the issuance or delivery of certificates for Warrant Shares or other
securities in respect of the Warrant Shares to any person or entity other than

exercise hereof, nor shall anything contained herein be construed to confer upon
the holder of this Warrant, as such, the rights of a stockholder of the Company
or the right to vote for the election of directors or upon any matter submitted
to stockholders at any meeting thereof, or give or withhold consent to any
corporate action or to receive notice of meetings or other actions affecting
stockholders (except as provided herein), or to receive dividends or

as the case may be, to the Holder. If the Holder and the Company are unable

arithmetic calculation being submitted to the Holder, then the Company shall,
within two Business Days, submit via facsimile (a) the disputed determination of
the Exercise Price to an independent, reputable investment bank selected by the
Company and approved by the Holder or (b) the disputed arithmetic calculation of
the Warrant Shares to the Company’s independent, outside accountant. The Company

may be, to perform the determinations or calculations and notify the Company and
the Holder of the results no later than ten (10) Business Days from the

covenants that it will use commercially reasonable efforts to 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 Shares upon the exercise
of this Warrant and use commercially reasonable efforts to obtain all such

from the Company’s stockholders or Board of Directors or any public regulatory
