                             STORAGENETWORKS, INC.

                       2000 EMPLOYEE STOCK PURCHASE PLAN

     The purpose of this 2000 Employee Stock Purchase Plan (the "Plan") is to
provide eligible employees of StorageNetworks, Inc., a Delaware corporation (the
"Company"), and certain of its subsidiaries with opportunities to purchase
shares of the Company's common stock, $0.01 par value (the "Common Stock").
This Plan is intended to qualify as an "employee stock purchase plan" as defined
in Section 423 of the Internal Revenue Code of 1986, as amended (the "Code"),
and the regulations promulgated thereunder, and shall be interpreted consistent
therewith.

     1.  Administration.  The Plan will be administered by the Company's Board
of Directors (the "Board") or by a Committee appointed by the Board (the
"Committee").  The Board or the Committee has authority to make rules and
regulations for the administration of the Plan and its interpretation and
decisions with regard thereto shall be final and conclusive.

     2.  Eligibility.  All employees of the Company, including Board members who
are employees, and all employees of any subsidiary of the Company (as defined in
Section 424(f) of the Code) designated by the Board or the Committee from time
to time (a "Designated Subsidiary"), are eligible to participate in any one or
more of the offerings of Options (as defined in Section 9) to purchase Common
Stock under the Plan provided that:

          (a) they are customarily employed by the Company or a Designated
     Subsidiary for more than 20 hours a week and for more than five months in a
     calendar year; and

          (b) for the first Offering (as defined below), they were employed by
     the Company or a Designated Subsidiary on or before the date that is at
     least 30 days prior to the first Offering Commencement Date (as described
     in Section 4 below), and for each subsequent Offering, they have been
     employed by the Company or a Designated Subsidiary for at least one month
     prior to enrolling in the Plan; and

          (c) they are employees of the Company or a Designated Subsidiary on
     the first day of the applicable Plan Period (as defined below).

  No employee may be granted an option hereunder if such employee, immediately
after the option is granted, owns 5% or more of the total combined voting power
or value of the stock of the Company or any subsidiary.  For purposes of the
preceding sentence, the attribution rules of Section 424(d) of the Code shall
apply in determining the stock ownership of an employee, and all stock which the
employee has a contractual right to purchase shall be treated as stock owned by
the employee.

     3.  Stock Subject to the Plan.  Subject to adjustment under Section 15
below,  1,000,000 shares of Common Stock may be issued under this Plan,
increased annually on the first day of March, beginning on March 1, 2001, by an
amount equal to the number of shares of Common Stock required to restore the
total number of shares of Common Stock then available for issuance under the
Plan to 1,000,000; provided, however, that the maximum number of shares issuable
under the Plan shall not exceed 10,000,000 shares of Common Stock.

     4.  Offerings.  The Company will make one or more offerings ("Offerings")
to employees to purchase stock under this Plan.  Offerings will begin on such
date or dates as may be established by the Board from time to time (the
"Offering Commencement Dates"), provided that the first Offering Commencement
Date shall be the later of (i) November 1, 2000, or (ii) such other date as the
Board of Directors in its discretion shall determine, if trading of the Common
Stock shall not have commenced on or prior to June 1, 2000 on the Nasdaq
National Market in connection with an initial public offering of Common Stock
pursuant to an effective registration statement under the Securities Act of
1933, as amended (the "Securities Act"), and the first Offering will terminate,
in the case of clause (i) above, on April 30, 2001, and in the case of (ii)
above, on such other date as the Board of Directors in its discretion shall
determine.  After the first Offering, each Offering Commencement Date will begin
a six-month period (a "Plan Period") during which payroll deductions will be
made and held for the purchase of Common Stock at the end of the Plan Period.
Unless the Board or the Committee in its  discretion, chooses a different Plan
Period, each Offering subsequent to the first Offering shall have a Plan Period
of six months, beginning on November 1 and May 1 of each year.

     5.  Participation.  An employee eligible on the Offering Commencement Date
of any Offering may participate in such Offering by completing and forwarding a
payroll deduction authorization form to the employee's appropriate payroll
office at least 14 days prior to the applicable Offering Commencement Date.  The
form will authorize a regular payroll deduction from the Compensation (as
defined below) received by the employee during the Plan Period.  Unless an
employee files a new form or withdraws from the Plan, his or her deductions and
purchases will continue at the same rate for future Offerings under the Plan as
long as the Plan remains in effect.  The term "Compensation" means the amount of
money reportable on the employee's Federal Income Tax Withholding Statement,
excluding overtime, shift premium, sales commissions, incentive or bonus awards,
allowances and reimbursements for expenses such as relocation allowances for
travel expenses, income or gains on the exercise of Company stock options or
stock appreciation rights, and similar items, whether or not shown on the
employee's Federal Income Tax Withholding Statement.

     6.  Deductions.  The Company will maintain payroll deduction accounts for
all participating employees.  With respect to any Offering made under this Plan,
an employee may authorize a payroll deduction, as set forth below, from the
Compensation he or she receives during the Plan Period or such shorter period
during which deductions from payroll are made.  Payroll deductions may be at the
rate of 1%, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9% or 10% of Compensation.

                                      -2-

  No employee may be granted an Option (as defined in Section 9) which permits
his or her rights to purchase Common Stock under this Plan and any other
employee stock purchase plan (as defined in Section 423(b) of the Code) of the
Company and its subsidiaries, to accrue at a rate which exceeds $25,000 of the
fair market value of such Common Stock (determined at the Offering Commencement
Date of the Plan Period) for each calendar year in which the Option is
outstanding at any time.

     7.  Deduction Changes.  An employee may decrease or discontinue his or her
payroll deduction once during any Plan Period, by filing a new payroll deduction
authorization form.  However, an employee may not increase his or her payroll
deduction during a Plan Period.  If an employee elects to discontinue his or her
payroll deductions during a Plan Period, but does not elect to withdraw his or
her funds pursuant to Section 8 hereof, funds deducted prior to his or her
election to discontinue will be applied to the purchase of Common Stock on the
Exercise Date (as defined below).

     8.  Interest.  Interest will not be paid on any employee accounts, except
to the extent that the Board or the Committee, in its sole discretion, elects to
credit employee accounts with interest at such per annum rate as it may from
time to time determine.

     9.  Withdrawal of Funds.  An employee may at any time prior to the close of
business on the last business day in a Plan Period and for any reason
permanently draw out the balance accumulated in the employee's account and
thereby withdraw from participation in an Offering.  Partial withdrawals are not
permitted.  The employee may not begin participation again during the remainder
of the Plan Period.  The employee may participate in any subsequent Offering in
accordance with terms and conditions established by the Board or the Committee.

     10.  Purchase of Shares.  On the Offering Commencement Date of each Plan
Period, the Company will grant to each eligible employee who is then a
participant in the Plan an option ("Option") to purchase on the last business
day of such Plan Period (the "Exercise Date"), at the Option Price hereinafter
provided for, the largest number of whole shares of Common Stock of the Company
as does not exceed the number of shares determined by multiplying $2,083 by the
number of full months in the Offering Period and dividing the result by the
closing price (as defined below) on the Offering Commencement Date of such Plan
Period.

  The purchase price for each share purchased will be 85% of the closing price
of the Common Stock on (i) the first business day of such Plan Period or (ii)
the Exercise Date, whichever closing price shall be less.  Such closing price
shall be (a) the closing price on any national securities exchange on which the
Common Stock is listed, (b) the closing price of the Common Stock on the Nasdaq
National Market or (c) the average of the closing bid and asked prices in the
over-the-counter-market, whichever is applicable, as published in The Wall
Street Journal.  If no sales of Common Stock were made on such a day, the price
of the Common Stock for purposes of clauses (a) and (b) above shall be the
reported price for the next preceding day on which sales were made.  Each
employee who continues to be a participant in the Plan on the Exercise Date
shall be deemed to have exercised his or her Option at the Option Price on such
date and shall be deemed to have purchased from the Company the number of full
shares of Common Stock reserved for the purpose of the Plan that his or her
accumulated payroll

                                      -3-
<PAGE>

deductions on such date will pay for, but not in excess of the maximum number
determined in the manner set forth above.

  Any balance remaining in an employee's payroll deduction account at the end of
a Plan Period will be automatically refunded to the employee, except that any
balance which is less than the purchase price of one share of Common Stock will
be carried forward into the employee's payroll deduction account for the
following Offering, unless the employee elects not to participate in the
following Offering under the Plan, in which case the balance in the employee's
account shall be refunded to the employee.

     10.  Issuance of Certificates.  Certificates representing shares of Common
Stock purchased under the Plan may be issued only in the name of the employee,
in the name of the employee and another person of legal age as joint tenants
with rights of survivorship, or (in the Company's sole discretion) in the name
of a brokerage firm, bank or other nominee holder designated by the employee.
The Company may, in its sole discretion and in compliance with applicable laws,
authorize the use of book entry registration of shares in lieu of issuing stock
certificates.

     11.  Rights on Retirement, Death or Termination of Employment.  In the
event of a participating employee's termination of employment prior to the last
business day of a Plan Period, no payroll deduction shall be taken from any pay
due and owing to an employee and the balance in the employee's account shall be
paid to the employee or, in the event of the employee's death, (a) to a
beneficiary previously designated in a revocable notice signed by the employee
(with any spousal consent required under state law), (b) in the absence of such
a designated beneficiary, to the executor or administrator of the employee's
estate or (c) if no such executor or administrator has been appointed to the
knowledge of the Company, to such other person(s) as the Company may, in its
discretion, designate.  If, prior to the last business day of the Plan Period,
the Designated Subsidiary by which an employee is employed shall cease to be a
subsidiary of the Company, or if the employee is transferred to a subsidiary of
the Company that is not a Designated Subsidiary, the employee shall be deemed to
have terminated employment for the purposes of this Plan.

     12.  Optionees Not Stockholders.  Neither the granting of an Option to an
employee nor the deductions from his or her pay shall constitute such employee a
stockholder of the shares of Common Stock covered by an Option under this Plan
until such shares have been purchased by and issued to him or her.

     13.  Rights Not Transferable.  Rights under this Plan are not transferable
by a participating employee other than by will or the laws of descent and
distribution, and are exercisable during the employee's lifetime only by the
employee.

     14.  Application of Funds.  All funds received or held by the Company under
this Plan may be combined with other corporate funds and may be used for any
corporate purpose.

     15.  Adjustment in Case of Changes Affecting Common Stock.  In the event of
any stock split, stock dividend, recapitalization, reorganization, merger,
consolidation, combination, exchange of shares, liquidation, spin-off or other
similar change in capitalization or event, or any

                                      -4-
<PAGE>

distribution to holders of Common Stock other than a normal cash dividend, the
number of shares approved for this Plan, the number of shares subject to any
outstanding Option and the purchase price thereof shall be adjusted
proportionately, and such other adjustment shall be made as may be deemed
equitable by the Board or the Committee. In the event of any other change
affecting the Common Stock, such adjustment shall be made as may be deemed
equitable by the Board or the Committee to give proper effect to such event.

     16.  Merger.  If the Company shall at any time merge or consolidate with
another corporation and the holders of the capital stock of the Company
immediately prior to such merger or consolidation continue to hold at least 80%
by voting power of the capital stock of the surviving corporation ("Continuity
of Control"), the holder of each Option then outstanding will thereafter be
entitled to receive at the next Exercise Date upon the exercise of such Option
for each share as to which such Option shall be exercised the securities or
property which a holder of one share of the Common Stock was entitled to upon
and at the time of such merger or consolidation, and the Board or the Committee
shall take such steps in connection with such merger or consolidation as the
Board or the Committee shall deem necessary to assure that the provisions of
Section 15 shall thereafter be applicable, as nearly as reasonably may be, in
relation to the said securities or property as to which such holder of such
Option might thereafter be entitled to receive thereunder.

  In the event of a merger or consolidation of the Company with or into another
corporation which does not involve Continuity of Control, or of a sale of all or
substantially all of the assets of the Company while unexercised Options remain
outstanding under the Plan, all outstanding Options shall be cancelled by the
Board or the Committee as of the effective date of any such transaction,
provided that notice of such cancellation shall be given to each holder of an
Option, and each holder of an Option shall have the right to exercise such
Option in full based on payroll deductions then credited to his or her account
as of a date determined by the Board or the Committee, which date shall not be
less than ten (10) days preceding the effective date of such transaction.

     17.  Amendment of the Plan.  The Board may at any time, and from time to
time, amend this Plan in any respect, except that (a) if the approval of any
such amendment by the stockholders of the Company is required by Section 423 of
the Code, such amendment shall not be effected without such approval, and (b) in
no event may any amendment be made which would cause the Plan to fail to comply
with Section 423 of the Code.

     18.  Insufficient Shares.  In the event that the total number of shares of
Common Stock specified in elections to be purchased under any Offering plus the
number of shares purchased under previous Offerings under this Plan exceeds the
maximum number of shares issuable under this Plan, the Board or the Committee
will allot the shares then available on a pro rata basis.

     19.  Termination of the Plan.  This Plan may be terminated at any time by
the Board.  Upon termination of this Plan all amounts in the accounts of
participating employees shall be promptly refunded.

     20.  Governmental Regulations.  The Company's obligation to sell and
deliver Common Stock under this Plan is subject to listing on a national stock
exchange or quotation on

                                      -5-
<PAGE>

the Nasdaq National Market and the approval of all governmental authorities
required in connection with the authorization, issuance or sale of such stock.

     21.  Governing Law.  The Plan shall be governed by Delaware law except to
the extent that such law is preempted by federal law.

     22.  Issuance of Shares.  Shares may be issued upon exercise of an Option
from authorized but unissued Common Stock, from shares held in the treasury of
the Company, or from any other proper source.

     23.  Notification upon Sale of Shares.  Each employee agrees, by entering
the Plan, to promptly give the Company notice of any disposition of shares
purchased under the Plan where such disposition occurs within two years after
the date of grant of the Option pursuant to which such shares were purchased or
one year after the date of exercise of the Option.

     24.  Effective Date and Approval of Stockholders.  The Plan shall take
effect upon the effectiveness of the Company's registration statement under the
Securities Act relating to the Company's initial public offering of Common
Stock, subject to approval by the stockholders of the Company as required by
Section 423 of the Code, which approval must occur within twelve months of the
adoption of the Plan by the Board.

                                         Approved by the Board of Directors on
                                         March 22, 2000
