 SAVVIS COMMUNICATIONS
CORPORATION, a Delaware corporation (hereinafter called the “Corporation”), for value received, hereby promises to pay                  or any
permitted transferee (the “Holder”), the principal sum of                  

 dollars ($            ), in a single installment on
January 30, 2009 (the “Maturity Date”), or the next preceding Business Day (as defined below) with interest (computed on the basis of a 365-day year for the actual number of days lapsed) from the date hereof on the unpaid principal
amount hereof. Such interest shall accrue at the rate of (a) 12.5% per annum until the date that is 360 days from February 9, 2004 and (b) 15% per annum thereafter, in each case, payable on each June 30 and December 31, beginning on June 30, 2004,
(each such day being an “Interest Payment Date”), by the issuance of an additional Note or Notes (each a “PIK Note”) by the Corporation in favor of the Holder, in substantially the form hereof, in a principal amount
equal to the interest payable to such holder on such Interest Payment Date, until the principal amount hereof shall have become due and payable, whether at maturity or by acceleration or otherwise, and thereafter at the lesser of (x) 20% per annum
and (y) the highest rate permitted by applicable law on any overdue principal amount. Delivery of any PIK Notes shall be made by the Corporation to the Holder within five Business Days of an applicable Interest Payment Date. 
  
 The payment of principal and interest on this Note shall be in such currency
of the United States of America as at the time of payment shall be legal tender for payment of public and private debts. 
  
 If for any reason one or more PIK Notes shall not be delivered in accordance herewith, interest on the unpaid principal of each PIK Note shall accrue from
the Interest Payment Date in respect of which such PIK Note should have been issued until repayment in cash of the principal and payment in cash of all accrued interest in full or delivery of the applicable PIK Note. Interest shall accrue on this
Note such that the aggregate interest due and payable on the Maturity Date and on each Interest Payment Date would be the same as if all PIK Notes not issued had been issued in accordance with the terms of this Note, and the principal payable on the
Maturity Date with respect to this Note shall be an amount equal to the sum of the principal outstanding hereunder and the aggregate principal which would be outstanding if the PIK Notes not issued had been issued in accordance with the terms of
this Note. 
  
 For purposes of this Note, “Business
Day” shall mean any day other than a Saturday, Sunday or a legal holiday under the laws of the State of New York. 
  
 1. Notes. This Note is issued pursuant to the Amended and Restated Securities Purchase Agreement, dated as of February 9, 2004 (the
“Purchase Agreement”), by and among the Corporation and the purchaser parties thereto, providing for, among other things, the issuance of Series A Subordinated Notes (such Series A Subordinated Notes (including the PIK Notes) are
referred to herein collectively as the “Notes”). Capitalized terms used herein but not otherwise defined shall have the meaning ascribed to them in the Purchase Agreement. 
  
 2. Transfer or Exchange of Notes. The Corporation shall keep at its
office or agency maintained as provided in subsection (a) of Section 9 a register in which the Corporation shall provide for the registration of Notes and for the registration of transfer and exchange of Notes. The holder of this Note may, at its
option, and either in person or by duly authorized attorney, surrender the same for registration of transfer or exchange at the office or 
  

 2 

 agency of the Corporation maintained as provided in subsection (a) of Section 9, and, without expense to such holder
(except for taxes or governmental charges imposed in connection therewith), receive in exchange therefore a Note or Notes in such denomination or denominations as such holder may request (but in any event in denominations of not less than $1,000
principal amount), dated as of the date to which interest has been paid on the Note or Notes so surrendered for transfer or exchange, for the same aggregate principal amount as the then unpaid principal amount of the Note or Notes so surrendered for
transfer or exchange, and registered in the name of such person or persons as may be designated by such holder. Every Note presented or surrendered for registration of transfer or exchange shall be duly endorsed, or shall be accompanied by a written
instrument of transfer, satisfactory in form to the Corporation, duly executed by the holder of such Note or his attorney, duly authorized in writing. Every Note so made and delivered in exchange for this Note shall in all other respects be in the
same form and have the same terms as this Note. No transfer or exchange of any Note shall be valid unless made in the foregoing manner at such office or agency. Notwithstanding anything to the contrary contained herein, this Note may not be
transferred by the Holder (other than to a parent, subsidiary, successor or affiliate of such Holder or to those participants set forth on Annex II to the Purchase Agreement) during the six-month period immediately succeeding the date hereof without
the prior written consent of Welsh, Carson, Anderson & Stowe VIII, L.P., which will be granted or withheld in its sole commercially reasonable judgment. 
  
 3. Loss, Theft, Destruction or Mutilation of Note. Upon receipt of evidence satisfactory to the Corporation of the loss, theft, destruction or
mutilation of this Note, and, in the case of any such loss, theft or destruction, upon receipt of an affidavit of loss from the holder hereof reasonably satisfactory to the Corporation, or, in the case of any such mutilation, upon surrender and
cancellation of this Note, the Corporation will make and deliver, in lieu of this Note, a new Note of like tenor and unpaid principal amount and dated as of the date to which interest has been paid on this Note. 
  
 4. Persons Deemed Owners; Holders. The Corporation may deem and treat
the person in whose name any Note is registered as the owner and holder of such Note for the purpose of receiving payment of principal and premium, if any, and interest on such Note and for all other purposes whatsoever, whether or not such Note
shall be overdue. With respect to any Note at any time outstanding, the term “holder,” as used herein, shall be deemed to mean the person in whose name such Note is registered as aforesaid at such time. 
  
 5. Early Redemption. 
  
 (a) Upon Change of Control. The Corporation shall promptly notify the
Holder of a Change of Control. Upon receipt of such notice, the Holder shall have the right during the 30 day period after receipt of such notice to require the Corporation, subject to the terms of the Subordination Agreement, to redeem any or all
of this Note at a cash price equal to 100% of the principal amount of this Note, plus all accrued and unpaid interest as of the effective date of the Change of Control. 
  

 3 

 (b) Optional Prepayment by the Corporation. Prior to the date that is 360 days from February 9,
2004, the Corporation shall have the right, subject to the terms of the Subordination Agreement, to prepay in cash the outstanding principal amount of the Notes in whole or in part in increments of not less than $5,000,000 principal amount with all
accrued and unpaid interest to the date of prepayment, at any time without premium or penalty, upon at least 3 Business Days’ notice of the date of prepayment. Prepayments shall be applied pro rata among the holders of the Notes based on the
outstanding principal amounts thereof. From the date that is 360 days from February 9, 2004 through January 29, 2008, the Company shall have the right, subject to the terms of the Subordination Agreement, to prepay in cash the entire principal
amount, and only the entire principal amount, of this Note with all accrued and unpaid interest to the date of prepayment, at any time, in cash in an amount equal to the entire outstanding principal amount, all accrued and unpaid interest to the
date of prepayment, and the Make-Whole Premium, upon at least 3 Business Days’ notice of the date of prepayment. From and after January 30, 2008, the Corporation shall have the right, subject to the terms of the Subordination Agreement, to
prepay in cash the entire principal amount, and only the entire principal amount, of this Note with all accrued and unpaid interest to the date of prepayment, at any time, in cash in an amount equal to 101% of the entire outstanding principal amount
and all accrued and unpaid interest to the date of repayment, upon at least 3 Business Days’ notice of the date of prepayment. Except as provided in this Section 5, the Notes may not be prepaid. 
  
 For purposes of this Note, “Make-Whole Premium” shall mean
the sum of (x) the sum of the present values of all remaining scheduled payments of interest on this Note and all PIK Notes required to be issued with respect to this Note and such PIK Notes through and including January 30, 2008 from the effective
date of the proposed refinancing (the “Refinancing Date”) discounted semi-annually on each Interest Payment Date at a rate equal to the Treasury Rate plus 0.50%, based on a 360-day year of twelve 30-day months and (y) 1% of the
principal amount of such Note. 
  
 For purposes of this Note,
“Treasury Rate” means a per annum rate (expressed as a semi-annual equivalent and as a decimal and, in the case of United States Treasury bills, converted to a bond equivalent yield) determined to be the per annum rate equal to the
yield for U.S. Treasury securities as indicated by Bloomberg Financial Markets (page PX1 or the relevant page at the date of determination indicating such yields) (or, if such data ceases to be available, any publicly available source of similar
market data) at approximately 10:00 A.M., New York city time, on the third Business Day prior to the Refinancing Date, and shall be the yield on the U.S. Treasury security having a constant maturity to January 30, 2008; provided, that if January 30,
2008 is not the maturity of a U.S. Treasury security, such yield shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the yields of the U.S. Treasury securities having constant maturities closest to
January 30, 2008. 
  
 6. Notice of Prepayment and Other
Notices. The Corporation shall give written notice of any prepayment of this Note pursuant to Section 5 not less than 3 Business Days prior to the date fixed for such prepayment. Such notice shall include a reasonably-detailed description of the
consideration, if any, to be received by holders of Common Stock in 
  

 4 

 connection with the related Change of Control, if applicable. Such notice of prepayment and all other notices to be given
to any holder of this Note shall be given by registered or certified mail to the person in whose name this Note is registered at its address designated on the register maintained by the Corporation on the date of mailing such notice of prepayment or
other notice. Upon notice of prepayment being given as aforesaid, the Corporation covenants and agrees that it will prepay, on the date therein fixed for prepayment, the entire principal amount hereof together with interest accrued hereon in cash in
an amount determined pursuant to Section 5. Notwithstanding the foregoing, any such notice may specify that the obligation to make such prepayment is conditional upon the closing of the transaction requiring such prepayment, and no prepayment shall
be required unless and until such transaction is consummated. 
  
 7. Interest and Premium After Date Fixed for Prepayment. If this Note is to be prepaid pursuant to Section 5 hereof, this Note shall (unless the provisions of the last sentence of Section 6 become applicable) cease to bear interest
on and after the date fixed for such prepayment unless, upon presentation for the purpose, the Corporation shall fail to pay this Note, in which event the principal amount of this Note, and, so far as may be lawful, any overdue installment of
interest, shall bear interest on and after the date fixed for such prepayment and until paid at the rate per annum provided herein for overdue principal. 
  

8. Surrender of Notes; Notation Thereon. As a condition to obtaining any payment of all or any portion of the principal amount of this Note, the
Corporation may require the holder hereof to surrender this Note, and in such event the Corporation will execute and deliver at the expense of the Corporation, upon such surrender, a new Note registered in the name of such person or persons as may
be designated by such holder for the principal amount of this Note then remaining unpaid, dated as of the date to which interest has been paid on the principal amount of this Note then remaining unpaid. 
  
 9. Affirmative Covenants. The Corporation covenants and agrees that,
so long as any Note shall be outstanding: 
  
 (a) Maintenance
of Office. The Corporation will maintain an office or agency in Town and Country, Missouri (or such other place in the United States of America as the Corporation may designate in writing to the registered holder hereof), where the Notes may be
presented for registration of transfer and for exchange as herein provided, where notices and demands to or upon the Corporation in respect of the Notes may be served and where, at the option of the holders thereof, the Notes may be presented for
payment. Until the Corporation otherwise notifies the holders of the Notes, said office shall be the principal office of the Corporation in Town and Country, Missouri. 
  
 (b) Payment of Taxes. The Corporation will promptly file all tax returns required to be filed in any jurisdiction and
pay and discharge or cause to be paid and discharged, before the same shall become in default, all lawful taxes and assessments imposed upon the Corporation or any subsidiary or upon the income and profits of the Corporation or any subsidiary, or
upon any property, real, personal or mixed, belonging to the Corporation or any subsidiary, or upon 
  

 5 

 any part thereof by the United States or any State or locality thereof, as well as all lawful claims for labor, materials
and supplies, which, if unpaid, would become a lien or charge upon such property or any part thereof; provided, however, that the Corporation shall not be required to pay and discharge or to cause to be paid and discharged any such
tax, assessment, charge, levy or claim (i) so long as both (x) the Corporation has set aside adequate reserves for such tax, assessment, charge, levy or claim in accordance with GAAP on the books of the Corporation and (y) the Corporation shall be
contesting the validity thereof on a timely basis in good faith by appropriate proceedings or the Corporation shall, in its good faith judgment, deem the validity thereof to be questionable and the party to whom such tax, assessment, charge, levy or
claim is allegedly owed shall not have made written demand for the payment thereof or (ii) where the failure to pay or discharge would not have a material adverse effect on the properties, assets, financial condition, operating results, business or
prospects of the Corporation and its subsidiaries, taken as a whole (a “Material Adverse Effect”). 
  
 (c) Corporate Existence. The Corporation will do or cause to be done all things necessary and lawful to preserve and keep in full force and effect
its corporate existence, rights and franchises under the laws of the United States or any State thereof; provided, however, that nothing in this subsection (c) shall prevent a consolidation or merger of, or a sale, transfer or
disposition of all or any substantial part of the property and assets of, the Corporation, or the abandonment or termination of any rights or franchises of the Corporation, if such abandonment or termination is, in the good faith business judgment
of the Corporation, in the best interests of the Corporation or would not have a Material Adverse Effect. 
  
 (d) Maintenance of Property. The Corporation will at all times maintain and keep, or cause to be maintained and kept, in good repair, working order
and condition all significant properties of the Corporation used in the conduct of the business of the Corporation, and will from time to time make or cause to be made all needful and proper repairs, renewals, replacements, betterments and
improvements thereto, so that the business carried on in connection therewith may be properly and advantageously conducted at all times; provided, however, that nothing in this subsection (d) shall require the making of any repair or
renewal or the continuance of the operation and maintenance of any property or the retention of any assets, if such action (or inaction) is, in the good faith business judgment of the Corporation, in the best interests of the Corporation or would
not have a Material Adverse Effect. 
  
 (e) Insurance. The
Corporation will keep adequately insured, by financially sound and reputable insurers, all property of a character usually insured by corporations engaged in the same or a similar business similarly situated against loss or damage of the kinds
customarily insured against by such corporations and carry, with financially sound and reputable insurers, such other insurance (including, without limitation, liability insurance) in such amounts as are available at reasonable expense and to the
extent believed necessary in the good faith business judgment of the Corporation. 
  

 6 

 (f) Keeping of Books. The Corporation will at all times keep proper books of record and account in
which proper entries will be made of its transactions in accordance with generally accepted accounting principles consistently applied. 
  
 (g) Notice of Default. If any one or more events which constitute, or which with notice or lapse of time or both would constitute, an Event of
Default under Section 12 shall occur, or if the holder of any Note shall demand payment or take any other action permitted upon the occurrence of any such Event of Default, the Corporation shall immediately after it becomes aware that any such event
would with or without notice or lapse of time or both constitute such an Event or that such demand has been made or that any such action has been taken, give notice to the holder of this Note, specifying the nature of such event or of such demand or
action, as the case may be; provided, however, that if such event, in the good faith judgment of the Corporation, will be cured within ten Business Days after the Corporation has knowledge that such event would, with or without notice
or lapse of time or both, constitute such an Event of Default, no such notice need be given if such Event of Default shall be cured within such ten-Business Day period. 
  
 (h) Information Covenants. The Corporation will furnish each Holder: 
  
 (i) Annual Financial Statements. As soon as

however, that notwithstanding the foregoing, the Corporation will not furnish to any Holder any material non-public information regarding the Corporation unless such Holder shall have signed a confidentiality agreement reasonably acceptable
to the Corporation agreeing to maintain such information confidential and to refrain from trading in the Common Stock until the Corporation has advised such Holder, or such Holder otherwise discovers, that such information has ceased to be material
or has been disclosed to the public. 
  
 (j) At the request of the
holders of at least a majority in aggregate principal amount of the Notes at the time outstanding (other than those owned beneficially or of record by Welsh, Carson, Anderson & Stowe VIII, L.P. or any of its affiliated investment limited
partnerships or individuals that are affiliates thereof), the Corporation shall use commercially reasonable best efforts to obtain a cusip number for the Notes and take action necessary to have the Notes be DTC eligible (it being understood that a

written consent of the holders as herein provided, the Corporation shall transmit a copy of such modification or waiver to all the holders of the Notes at the time outstanding. 
  
 12. Events of Default. If any one or more of the following events, herein called “Events of
Default,” shall occur, for any reason whatsoever, and whether such occurrence shall, on the part of the Corporation, be voluntary or involuntary or come about or be effected by operation of law or pursuant to or in compliance with any

shall continue undismissed or unstayed for a period of 60 consecutive days; or 
  
 (e) a default by the Corporation of its obligations under Section 10(a) hereof shall have occurred and such default shall continue for 30
days; 
  
 then, the holder or holders of at least 66-2/3% in aggregate principal
amount of the Notes at the time outstanding (other than those owned beneficially or of record by Welsh, Carson, Anderson & Stowe VIII, L.P. or any of its affiliated investment limited partnerships or individuals that are affiliates thereof) may,
at its or their option (subject to the terms of the Subordination Agreement), by written notice to the Corporation, declare all the Notes to be, and all the Notes shall thereupon be and become, forthwith due and payable together with interest
accrued thereon without presentment, demand, protest or further notice of any kind, all of which are expressly waived to the extent permitted by law; provided, however, that, upon the occurrence and during the continuance of any of the
events specified in subsections (a) or (b) of this Section 12, the holder of any Note at the time outstanding may, at its option by notice in writing to the Corporation, subject to the terms of the Subordination Agreement, declare any Note or Notes

the extent permitted by law. 
  

 10 

 Notwithstanding the foregoing, upon the occurrence and during the continuance of any of the events specified in
subsections (c) and (d) of this Section 12, the Notes shall automatically, with no further action on the part of the Holder, be forthwith due and payable together with the interest accrued thereon. 
  
 At any time after any declaration of acceleration has been made as provided
in this Section 12, the holders of at least 66 2/3% in principal amount of the Notes then outstanding (other than
Notes owned beneficially or of record by Welsh, Carson, Anderson & Stowe VIII, L.P. or any of its affiliated investment limited partnerships or individuals that are affiliates thereof) may, by notice to the Corporation, rescind such declaration
and its consequences if the Corporation has paid all overdue installments of interest on the Notes and all principal (and premium, if any) that has become due otherwise than by such declaration of acceleration; and all other defaults and Events of
Default (other than nonpayments of principal and interest that have become due solely by reason of acceleration) shall have been remedied or cured or shall have been waived pursuant to this paragraph; provided, however, that no such
rescission shall extend to or affect any subsequent default or Event of Default or impair any right consequent thereon. 
  
 Without limiting the foregoing, the Corporation hereby waives any right to trial by jury in any legal proceeding related in any way to this Note or the
Notes and agrees that any such proceeding may, if the holder so elects, be brought and enforced in any state or, if applicable federal court, located in New York City in the Borough of Manhattan and the Corporation hereby waives any objection to
jurisdiction or venue in any such proceeding commenced in such court. The Corporation further agrees that any process required to be served on it for purposes of any such proceeding may be served on it, with the same effect as personal service on it
within the State of Delaware, by registered mail addressed to it at its office or agency set forth in Section 19 for purposes of notices hereunder. 
  
 13. Suits for Enforcement. In case any one or more of the Events of Default specified in Section 12 of this Note shall happen and be continuing,
the holder of this Note may, subject to the terms of the Subordination Agreement, proceed to protect and enforce its rights by suit in equity, action at law and/or by other appropriate proceeding, whether for the specific performance of any covenant
or agreement contained in this Note or in aid of the exercise of any power granted in this Note, or, subject to the terms of the Subordination Agreement, may proceed to enforce the payment of this Note or to enforce any other legal or equitable
right of the holder of this Note. 
  
 In case of any default under
any Note, the Corporation will pay to the holder thereof such amounts as shall be sufficient to cover the out-of-pocket costs and expenses of such holder due to said default, including, without limitation, collection costs and reasonable

 WARRANT

  
 To Purchase Shares of Series B Convertible Preferred Stock
of 
 SAVVIS Communications Corporation, a Delaware corporation 
  
 1. Grant of Warrant. THIS IS TO CERTIFY THAT
            , or its registered assigns (the “Holder”), is entitled to exercise this Warrant to purchase from SAVVIS Communications Corporation, a Delaware
corporation (the “Company”), up to an aggregate of              shares of Series B Convertible Preferred Stock, par value $0.01 per share, of the Company (the
“Series B Stock”), subject to adjustment as set forth in accordance with Section 5 and exercisable in accordance with Section 3, all on the terms and conditions and pursuant to the provisions hereinafter set forth. This Warrant is
being granted pursuant to the terms of that certain Amended and Restated Securities Purchase Agreement dated as of February     , 2004 (the “Agreement”) by and among the Company, Welsh, Carson, Anderson
& Stowe VIII, L.P., the other purchaser parties thereto, and the Company and the Holder intend to be legally bound hereby and thereby. Any capitalized terms used herein but not defined herein shall have the meanings ascribed to them in the
Agreement. 
  
 2. Exercise Price. The purchase price
payable for each of the shares of Series B Stock sold upon exercise or exchange of this Warrant shall be $16.30 (the “Exercise Price”). Such Exercise Price and the number of shares of Series B Stock into which this Warrant is
exercisable or exchangeable are subject to adjustment from time to time as provided in Section 5. 
  
 3. Exercise. This Warrant may be exercised or exchanged in whole or in part at any time prior to January 30, 2009 (the “Expiration
Date”). 
  
 Subject to the foregoing, in order to
exercise or exchange this Warrant, in whole or in part, the Holder hereof shall deliver to the Company at its office at 12851 Worldgate Drive, 
  

 1 

 Herndon, Virginia 20170 Attention: Chief Legal Officer, or at such other office as shall be designated by the Company
pursuant to the Agreement: 
  
 (a) written notice of the
Holder’s election to exercise or exchange this Warrant, which notice shall be substantially in the form of the attached “Subscription Form” and shall specify the number of shares of Series B Stock to be purchased pursuant to such
exercise or exchange; 
  
 (b) at the election of the Holder,
either (i) a wire transfer of immediately available funds to the Company or (ii) notice that the Exercise Price is satisfied by reduction of the number of shares to be received by the Holder upon exercise of this Warrant as provided in Section
4 below, with the amount of such reduction specified in such notice; in each case such wire transfer or reduction in the number of shares shall be in an amount equal to the aggregate purchase price for all shares of Series B Stock to be
purchased pursuant to such exercise or exchange; and 
  
 (c) this
Warrant, properly endorsed. 
  
 Upon receipt thereof, the Company shall, as
promptly as practicable, and in any event within ten (10) days thereafter, execute or cause to be executed and delivered to the Holder a certificate or certificates representing the aggregate number of fully paid and nonassessable shares of Series B
Stock issuable upon such exercise or exchange plus, in lieu of any fractional share to which such holder would otherwise be entitled, cash in an amount equal to such fraction multiplied by the then Current Market Value of one full share. The stock
certificate or certificates so delivered shall be registered in the name of the Holder or such other name as shall be designated in said notice. 
  
 “Current Market Value” means the Base Market Value multiplied by ten. “Base Market Value” means, on any date, the
average of the daily closing market prices of the Company’s common stock, par value $0.01 (the “Common Stock”) for each day for five trading days ending [one business day] [two business days] before such date as of which such a
price can be established in the manner set forth below. The closing market price for each such trading day shall be the last sale price on such day as reported in the Consolidated Last Sale Reporting System or as quoted in the National Association
of Securities Dealers Automated Quotation System, or if such last sale price is not available, the average of the closing bid and asked prices as reported in either such system, or in any other case the higher bid price quoted for such day as
reported by The Wall Street Journal and the National Quotation Bureau pink sheets. If there is no active public market, the value shall be the fair market value thereof as reasonably determined in good faith by the Board of Directors of the Company.

  
 This Warrant shall be deemed to have been exercised or
exchanged and such certificate or certificates shall be deemed to have been issued, and the 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 of that said notice, together with said payment and this Warrant, is received by the Company as aforesaid (the “Exercise Date”). Except as otherwise provided in the Agreement or this Warrant, the Holder of this Warrant shall
not, by virtue of its ownership of this Warrant, be entitled to any rights of a stockholder in the Company, either at law or in equity, obligated to purchase any shares of Series B Stock or subject to any liabilities on 
  

 2 

 such Holder as a stockholder of the Company; provided, however, that the Holder shall, for all purposes, be
deemed to have become the Holder of record of such shares on the Exercise Date. If the exercise or exchange is for less than all of the shares of Series B Stock issuable as provided in this Warrant, the Company shall issue a new Warrant of like
tenor and date for the balance of such shares issuable hereunder to the Holder. The Holder of this Warrant, by its acceptance hereof, consents to and agrees to be bound by and to comply with all of the provisions of this Warrant. 
  
 4. “Cashless” Exchange. At the election of the
Holder, the Holder may exchange this Warrant without a cash payment of the Exercise Price, by designating that the number of the shares of Series B Stock issuable to the Holder upon such exchange shall be reduced by the number of shares having a
Current Market Value as of the Exercise Date equal to the amount of the total Exercise Price for such exchange. In such instance, no cash or other consideration will be paid by the Holder in connection with such exchange other than the surrender of
the Warrant itself, and no commission or other remuneration will be paid or given by the Holder or the Company in connection with such exchange. If such exchange results in only a partial exchange of this Warrant, then the Company shall deliver to
the Holder a new Warrant evidencing the remaining rights under the Warrant, as provided in Section 3 above. 
  
 5. Adjustments. If any of the following events shall occur at any time or from time to time prior to the exercise or exchange of the
Warrant, the following adjustments shall be made in the Exercise Price and/or the number of shares then purchasable upon the exercise or exchange of the Warrant, as appropriate: 
  
 (a) “Stock Splits and Combinations.” In case the Company shall at any time or from time to time after the
date hereof (i) subdivide or split the outstanding shares of Common Stock, (ii) combine or reclassify the outstanding shares of Common Stock into a smaller number of shares or (iii) issue by reclassification of the shares of Common Stock any shares
of capital stock of the Company, then, and in each such case, the Exercise Price in effect immediately prior to such event or the record date therefor, whichever is applicable, shall be proportionately increased or reduced, as applicable, and the
aggregate number of shares for which this Warrant shall be exercisable or exchangeable shall be proportionately increased or reduced, as applicable, so that the Holder of this Warrant thereafter surrendered for exercise or exchange shall be entitled
to receive the number of shares of Series B Stock or other securities of the Company such that the number of shares of Common Stock into which such Series B Stock is convertible equals the number of shares of Common Stock which such Holder would
have owned or have been entitled to receive after the occurrence of any of the events described above, had such Warrant been surrendered for exercise or exchange, and the Series B Stock received upon such exercise or exchange been converted into
shares of Common Stock, immediately prior to the occurrence of such event or the record date therefor, whichever is applicable. An adjustment made pursuant to this subparagraph (a) shall become effective at the close of business on the day upon
which such corporate action becomes effective. Such adjustment shall be made successively whenever any event listed above shall occur. 
  
 (b) “Dividends and Distributions in Common Stock.” In case the Company shall at any time or from time to time after the date hereof pay a
dividend or make a distribution payable in shares of Common Stock on any class of Capital Stock of the Company other than dividends 
  

 3 

 or distributions of shares of Common Stock or other securities with respect to which adjustments are provided in
paragraph (a) above, the Exercise Price shall be reduced to the price determined by multiplying (i) the applicable Exercise Price by (ii) a fraction, the numerator of which shall be the number of shares of Common Stock theretofore outstanding and
the denominator of which shall be the sum of such number of shares and the total number of shares issuable in such dividend or distribution. An adjustment made pursuant to this subparagraph (b) shall become effective as of the close of business on
the record date of such dividend or distribution provided such plan to pay or deliver such dividend or distribution is not thereafter legally abandoned. The provisions of this clause shall similarly apply to successive distributions. 
  
 (c) “Distribution of Indebtedness, Securities or Assets.” In
case the Company shall at any time or from time to time after the date hereof distribute to any holders of Common Stock (whether by dividend or in a merger, amalgamation, consolidation or otherwise) evidences of indebtedness, shares of Capital Stock
of any class or series, other securities, cash or assets (other than securities referred to in subparagraph (b) above or (e) below or a dividend payable exclusively in cash and other than as a result of a Fundamental Change) in respect of such
holder’s Common Stock, the Exercise Price in effect immediately prior to the close of business on the record date fixed for determination of stockholders entitled to receive such distribution shall be reduced by multiplying such Exercise Price
by a fraction, the numerator of which is the Volume Weighted Market Value on such record date less the fair market value (as determined by the Board of Directors of the Company, whose determination in good faith shall be conclusive) of the portion
of such evidences of indebtedness, shares of Capital Stock, other securities, cash and assets so distributed applicable to one share of Common Stock and the denominator of which is the Volume Weighted Market Value. Such adjustment shall be made
successively whenever any such event shall occur. “Capital Stock” means as to any entity (whether a corporation, partnership or another entity), corporate stock and any and all shares, partnership interests, limited partnership
interests, limited liability company interests, membership interests, equity interests, participations, rights or other equivalents (however designated) of corporate stock or any of the foregoing issued by any such entity. “Volume Weighted
Market Value” means, at any date, the price per share of Common Stock which equals (i) the sum of the products, for each of the 20 trading days prior to such date, of the Closing Market Price on such date, multiplied by the volume of shares
traded on such date, (ii) divided by the total volume of shares traded during the 20 trading days prior to such date. If no Closing Market Price for shares of Common Stock can be determined, the Volume Weighted Market Value shall be the fair market
value thereof as reasonably determined in good faith by the Board of Directors of the Company. For purposes of this definition, “Closing Market Price” means, on any trading day, the last sale price for shares of Common Stock on such
day as reported in the Consolidated Last Sale Reporting System or as quoted in the National Association of Securities Dealers Automated Quotation System, or if such last sale price is not available, the average of the closing bid and asked prices as
reported in either such system, or in any other case the higher bid price quoted for such day as reported by The Wall Street Journal and the National Quotation Bureau pink sheets. 
  
 (d) “Fundamental Changes”. In case of any Fundamental Change, this Warrant shall be exercisable or
exchangeable for the kind and amount of stock, other securities, cash and assets which the Holder of a Warrant would have owned immediately after the Fundamental Change if the Holder had exercised or exchanged the Warrant, and converted the shares
of Series B Stock received upon such exercise or exchange into shares of Common Stock, immediately before the 
  

 4 

 effective date of the Fundamental Change (or anything that such stock, other securities or assets are later converted or
changed into). In any such case, appropriate adjustment shall be made in the application of the provisions of this Section 5 with respect to the rights of the Holder of the Warrant after the Fundamental Change to the end that the provisions of this
Section 5 shall be applicable after that event in a manner as nearly equivalent as practicable as before the Fundamental Change. The Company shall not consummate such Fundamental Change, unless, concurrently with the consummation of such Fundamental
Change, the surviving or successor entity, if other than the Company, or the acquiror in a sale of assets of the Company, shall assume in writing all of the obligations of the Company under this Warrant and mail to the Holder a copy thereof.
“Fundamental Change” means any transaction or event, including, without limitation, any merger, consolidation, sale of assets, reclassification, recapitalization, compulsory share exchange or liquidation, in which all or
substantially all outstanding shares of the Company’s common stock are converted into or exchanged for stock, other securities or assets. 
  
 (e) “Adjustment of Exercise Price Upon Issuance of Additional Shares of Common Stock.” 
  
 (i) In the event the Company shall issue Additional Shares of Common Stock
(including Additional Shares of Common Stock deemed to be issued pursuant to Section 5(e)(ii)), without consideration or for a consideration per share less than an amount equal to (a) the Exercise Price in effect on the date of and
immediately prior to such issue, divided by (b) ten (the “Base Exercise Price”), then, and in each such event, the Exercise Price will be recalculated in accordance with the following formula: the Exercise Price then in effect shall
be multiplied by a fraction, (x) the numerator of which shall be the number of shares of Common Stock outstanding immediately prior to such issuance (“Outstanding Common Stock”) plus the number of shares of Common Stock that the
aggregate consideration (determined in the manner provided in Section 5(e)(iii)) received by the Company for such issuance would purchase at the Base Exercise Price in effect immediately prior to such issuance; and (y) the denominator of
which shall be the number of shares of Outstanding Common Stock plus the number of Additional Shares of Common Stock. For purposes of the foregoing calculation, the term “Outstanding Common Stock” shall include, without limitation, shares
of Common Stock issued or issuable upon the exercise, exchange or conversion of outstanding securities, excluding Common Stock issuable upon the exercise, exchange or conversion of options, warrants or similar rights to acquire Common Stock, at a
price greater than the Volume Weighted Market Value as of the date of adjustment. “Additional Shares of Common Stock” means any shares of Common Stock issued (or deemed to have been issued pursuant to Section 5(e)(ii)) by the
Company other than: (a) Common Stock issued pursuant to a transaction described in Section 5(a) or 5(b), (b) shares of Common Stock issued or issuable upon conversion of the Company’s Series A Convertible Preferred Stock or Series B Convertible
Preferred Stock, (c) in addition to the shares of Common Stock described in (d) below, shares of Common Stock or options, warrants or similar rights to purchase shares of Common Stock, which shares are issuable or issued to employees, consultants or
directors of the Company directly or pursuant to a stock option, restricted stock, employee stock purchase or similar plan approved by the Board of Directors of the Company, and (d) shares of Common Stock issued or issuable upon conversion of all
securities convertible, exchangeable or exercisable for, or rights to purchase, shares of Common Stock validly issued and outstanding as of the date hereof. 
  

 5 

 (ii) In the case of the issuance of options to purchase or rights to subscribe for Common Stock,
securities by their terms or by agreement with the Company convertible into or exchangeable for Common Stock or options to purchase or rights to subscribe for such convertible or exchangeable securities, the following provisions shall be taken into
account in making the adjustment: 
  
 (A) The shares of Common
Stock deliverable upon exercise of such options to purchase or rights to subscribe for Common Stock shall be deemed to have been issued at the time such options or rights were issued and for a consideration equal to the consideration (determined in
the manner provided in Section 5(e)(iii)), if any, received by the Company upon the issuance of such options or rights plus the minimum exercise price provided in such options or rights (without taking into account potential antidilution
adjustments) for the Common Stock covered thereby. 
  
 (B) The
aggregate maximum number of shares of Common Stock deliverable upon conversion of or in exchange (assuming the satisfaction of any condition to convertibility or exchangeability, including without limitation, the passage of time, but without taking
into account potential antidilution adjustments, accrual of dividends or payment of any premiums or preferences conditioned upon the occurrence of specified transactions) for any such convertible or exchangeable securities or upon the exercise of
options to purchase or rights to subscribe for such convertible or exchangeable securities and subsequent conversion or exchange thereof shall be deemed to have been issued at the time such securities were issued or such options or rights were
issued and for a consideration equal to the consideration, if any, received by the Company for any such securities and related options or rights (excluding any cash received on account of accrued interest or accrued dividends), plus the minimum
additional consideration, if any, to be received by the Company (without taking into account potential antidilution adjustments) upon the conversion or exchange of such securities or the exercise of any related options or rights (the consideration
in each case to be determined in the manner provided in Section 5(e)(iii)). 
  
 (iii) In the case of the issuance of Common Stock for cash, the consideration shall be deemed to be the amount of cash paid therefor before deducting any reasonable discounts, commissions or other expenses allowed,
paid or incurred by the Company for any underwriting or otherwise in connection with the issuance and sale thereof. In the case of the issuance of the Common Stock for a consideration in whole or in part other than cash, the consideration other than
cash shall be deemed to be the fair value thereof as determined in good faith by the Board of Directors of the Company irrespective of any accounting treatment. 
  

(iv) Notwithstanding any other provisions of this Section 5(e), no adjustment of the Exercise Price pursuant to this Section 5(e)
shall have the effect of increasing the Exercise Price above the Exercise Price in effect immediately prior to such adjustment. 
  
 (f) “Number of Shares Upon Adjustment of Exercise Price.” Upon each adjustment of the Exercise Price, the Holder of a Warrant shall
thereafter be entitled to purchase, at the Exercise Price resulting from such adjustment, the number of shares obtained by multiplying the Exercise Price in effect immediately prior to such adjustment by the number of shares purchasable pursuant to
such Warrant immediately prior to such adjustment and dividing the product thereof by the Exercise Price resulting from such adjustment. 
  

 6 

 6. Taxes. The issuance of any Common Stock or other certificate upon the exercise or
exchange of this Warrant shall be made without charge to the registered Holder hereof, or for any tax in respect of the issuance of such certificate, unless such tax is imposed by law upon the Holder (including, without limitation, Federal, state or
local income taxes), in which case such taxes shall be paid by the Holder. The obligations of the parties under this Section shall survive any redemption, repurchase or acquisition of this Warrant or the Series B Stock issued upon exercise or
exchange of this Warrant by the Company, and any cancellation or termination of this Warrant. 
  
 7. Transfer. Except as otherwise provided under the Agreement, this Warrant and all options and rights hereunder are transferable, as to all or any part of the number of shares of Series B Stock
purchasable upon its exercise or exchange, by the Holder hereof in person or by its duly authorized attorney on the books of the Company upon surrender of this Warrant at the principal offices of the Company, together with the “Assignment
Form” attached hereto duly executed. The Company shall deem and treat the registered Holder of this Warrant at any time as the absolute owner hereof for all purposes and shall not be affected by any notice to the contrary. If this Warrant is
transferred in part, the Company shall, at the time of surrender of this Warrant, issue to the transferee a Warrant covering the number of shares of Common Stock transferred and to the transferor a Warrant covering the number of shares not
transferred. 
  
 8. Reservation of Shares. The
Company shall, at all times prior to the Expiration Date, reserve and keep available such number of authorized shares of its Series B Stock, solely for the purpose of effecting the exercise or exchange of this Warrant, as may from time to time be
issuable upon exercise of this Warrant. The Company shall use reasonable best efforts to obtain any authorization, consent, approval or other action by or make any filing with any court or administrative body that may be required under applicable
state securities laws in connection with the issuance of shares of Series B Stock upon exercise or exchange of the Warrant. 
  
 9. Registration of Shares. The shares of Common Stock issuable upon conversion of the Series B Stock issuable upon exercise or exchange of
this warrant shall constitute Covered Warrant Common Shares (as such term is defined in the Registration Rights Agreement). Each Holder of this Warrant shall be entitled to all of the benefits afforded to a holder of any such Covered Warrant Common
Shares under the Registration Rights Agreement and such Holder, by its acceptance of this Warrant, agrees to be bound by and to comply with the terms and conditions of the Registration Rights Agreement applicable to such holder as a holder of such
Covered Warrant Common Shares. The Company will, at its expense, obtain promptly and maintain the approval for listing on each such exchange, upon official notice of issuance, the shares of Common Stock issuable upon conversion of the Series B Stock
issuable upon exercise of this Warrant. 
  
 10. Applicable
Law. THIS WARRANT SHALL BE GOVERNED BY, CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PROVISIONS THEREOF. EACH OF THE PARTIES HEREBY SUBMITS TO PERSONAL JURISDICTION

  

 7 

 AND WAIVES ANY OBJECTION AS TO VENUE IN THE COUNTY OF NEW YORK, STATE OF NEW YORK. SERVICE OF PROCESS ON THE PARTIES IN
ANY ACTION ARISING OUT OF OR RELATING TO THIS AGREEMENT SHALL BE EFFECTIVE IF MAILED TO THE PARTIES IN ACCORDANCE WITH SECTION 8.04 OF THE AGREEMENT. THE PARTIES HERETO WAIVE ALL RIGHT TO TRIAL BY JURY IN ANY ACTION OR PROCEEDING TO ENFORCE OR
DEFEND ANY RIGHTS HEREUNDER. 
  
 11. Successors and
Assigns. This Warrant and the rights evidenced hereby shall inure to the benefit of, and be binding upon, the successors and assigns of the Holder hereof and shall be enforceable by any such Holder. In the event this Warrant is sold,
transferred or assigned, the transferor will give written notice to the Company within fifteen (15) days following such sale, transfer or assignment and in such notice designate the name and address of the transferee. 
  
 12. Exchange of Certificates for Warrants. This Warrant may be
exchanged, at the option of the Holder, and upon surrender of such Warrant to the Company, for another Warrant, or other Warrants of different denominations, of like tenor and representing in the aggregate the right to purchase a like number of
shares of Series B Stock. The Holder shall make such request in a writing delivered to the Company, and must surrender the Warrant to be so exchanged. Thereupon, the Company will execute and deliver to the Holder the new Warrants so requested. The
Warrant surrendered for exchange will be cancelled by the Company. 
  
 13. Replacement of Instruments. Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any certificate or instrument evidencing this Warrant,
and (a) in the case of loss, theft or destruction, of indemnity reasonably satisfactory to it (provided that if the Holder is an institutional lender or investor, its own agreement of indemnity shall be deemed to be satisfactory), or (b) in the case
of mutilation, upon surrender and cancellation thereof, the Company, at its expense, shall execute, register and deliver, in lieu thereof, a new certificate or instrument for an equal number of Warrants. 
  
 14. Notices of Certain Events. 
  
 (a) In the event of (i) any setting by the Company of a record date with
respect to the holders of any class of securities of the Company for the purpose of determining which of such holders are entitled to dividends or other distributions, or any right to subscribe for, purchase or otherwise acquire any shares of Common
Stock or any other securities or property, or to receive any other right; (ii) any capital reorganization of the Company, or reclassification or recapitalization of the Common Stock of the Company or any transfer of all or substantially all of the
assets of the Company to, or consolidation or merger of the Company with or into, any other entity or Person; or (iii) any involuntary dissolution, liquidation or winding-up of the Company; then, and in each such event, the Company will mail or
cause to be mailed to the Holder of the Warrant at the time (as reflected in the records of the Company), a notice specifying, as the case may be: (A) the date on which any such record is to be set for the purpose of such dividend, distribution or
right, and stating the amount and character of such dividend, distribution or right; or (B) the date on which any such reorganization, reclassification, recapitalization, transfer, 
  

 8 

 consolidation, merger, dissolution, liquidation or winding-up is to take place and the time, if any is to be fixed, as of
which the holders of record of Common Stock (or such other Capital Stock or securities receivable upon the exercise of this Warrant) shall be entitled to exchange their shares of Common Stock (or such other Capital Stock or securities) for
securities or other property deliverable upon such event. Any such notice shall be given, as provided in Section 8.04 of the Agreement, at least fifteen (15) days prior to the date therein specified and the Holder may exercise this Warrant at any
time within the fifteen (15) day period from the date of mailing of such notice. 
  
 (b) If there shall be any adjustment as provided in Section 5, or if the securities or property other than shares of Series B Stock of the Company shall become purchasable in lieu of shares of such Series B Stock upon
exercise or exchange of the Warrant, the Company shall forthwith cause written notice thereof to be sent, as provided in Section 8.04 of the Agreement, to the Holder of this Warrant at the address of such Person shown on the books of the Company,
which notice shall be accompanied by a certificate of the chief financial officer of the Company setting forth in reasonable detail the basis for the Holder becoming entitled to purchase such shares and the number of shares that may be purchased and
the Exercise Price thereof, or the facts requiring any such adjustment and the Exercise Price and the number of shares purchasable after such adjustment, or the kind and amount of any such securities or property so purchasable upon the exercise or
exchange of this Warrant, or the number of shares issued to the Holder as ownership protection, as the case may be. At the request of the Holder and upon surrender of this Warrant, the Company shall reissue this Warrant in a form conforming to such
adjustments. 
  
 15. Amendment and Waiver. Any term,
covenant, agreement or condition in this Warrant may be amended, or compliance therewith may be waived (either generally or in a particular instance and either retroactively or prospectively), by a written instrument or written instruments executed
by the Company and the Holder. 
  
 16. Remedies. The
Company stipulates that the remedies at law of the Holder of this Warrant in the event of any default or threatened default by the Company in the performance of or compliance with any of the terms of this Warrant are not and will not be adequate and
that, to the fullest extent permitted by law, such terms may be specifically enforced by a decree for the specific performance of any agreement contained herein or by an injunction against a violation of any of the terms hereof or otherwise.
