                              STORAGENETWORKS, INC.
                                 2000 STOCK PLAN

1.  Purpose


     The purpose of this 2000 Stock Plan (the "Plan") of StorageNetworks, Inc, a
Delaware corporation (the "Company"), is to advance the interests of the
Company's stockholders by enhancing the Company's ability to attract, retain and
motivate persons who make (or are expected to make) important contributions to
the Company by providing such persons with equity ownership opportunities and
performance-based incentives and thereby better aligning the interests of such
persons with those of the Company's stockholders.  Except where the context
otherwise requires, the term "Company" shall include any of the Company's
present or future subsidiary corporations as defined in Section 424(f) of the
Internal Revenue Code of 1986, as amended, and any regulations promulgated
thereunder (the "Code") and any other business venture (including, without
limitation, joint venture or limited liability company) in which the Company has
a significant interest, as determined by the Board of Directors of the Company
(the "Board").

2.  Eligibility


     All of the Company's employees, officers, directors, consultants and
advisors (and any individuals who have accepted an offer for employment) are
eligible to be granted options, restricted stock awards, or other stock-based
awards (each, an "Award") under the Plan.  Each person who has been granted an
Award under the Plan shall be deemed a "Participant".

3.  Administration, Delegation


     (a) Administration by Board of Directors. The Plan will be administered by
the Board of Directors of the Company. The Board shall have authority to grant
Awards and to adopt, amend and repeal such administrative rules, guidelines and
practices relating to the Plan as it shall deem advisable. The Board may correct
any defect, supply any omission or reconcile any inconsistency in the Plan or
any Award in the manner and to the extent it shall deem expedient to carry the
Plan into effect and it shall be the sole and final judge of such expediency.
All decisions by the Board shall be made in the Board's sole discretion and
shall be final and binding on all persons having or claiming any interest in the
Plan or in any Award. No director or person acting pursuant to the authority
delegated by the Board shall be liable for any action or determination relating
to or under the Plan made in good faith.

     (b) Appointment of Committees. To the extent permitted by applicable law,
the Board may delegate any or all of its powers under the Plan to one or more
committees or subcommittees of the Board (a "Committee"). All references in the
Plan to the "Board" shall mean the Board or a Committee of the Board to the
extent that the Board's powers or authority under the Plan have been delegated
to such Committee.

4.  Stock Available for Awards


     (a) Number of Shares. Subject to adjustment under Section 9 below, Awards
may be made under the Plan for 12,000,000 shares of common stock, $.01 par value
per share, of the Company (the "Common Stock"), such number to be increased
annually beginning on March 1, 2001, by the lesser of (i) 3,000,000 shares of
Common Stock; (ii) 4% of the outstanding shares of Common Stock on that date; or
(iii) a lesser amount as determined by the Board; provided, however, that the
maximum number of shares issuable under the Plan shall not exceed 120,000,000
shares of Common Stock. If any Award expires or is terminated, surrendered or
canceled without having been fully exercised or is forfeited in whole or in part
or results in any Common Stock not being issued, the unused Common Stock covered
by such Award shall again be available for the grant of Awards under the Plan,
subject, however, in the case of Incentive Stock Options (as hereinafter
defined), to any limitation required under the Code. Shares issued under the
Plan may consist in whole or in part of authorized but unissued shares or
treasury shares.

     (b) Per-Participant Limit. Subject to adjustment under Section 9 below, for
Awards granted after the Common Stock is registered under the Securities
Exchange Act of 1934 (the "Exchange Act"), the maximum number of shares of
Common Stock with respect to which Awards may be granted to any Participant
under the Plan shall be 1,000,000 shares per calendar year. The per-Participant
limit described in this Section 4(b) shall be construed and applied consistently
with Section 162(m) of the Code ("Section 162(m)").

5.  Stock Options


     (a) General. The Board may grant options to purchase Common Stock (each, an
"Option") and determine the number of shares of Common Stock to be covered by
each Option, the exercise price of each Option and the conditions and
limitations applicable to the exercise of each Option, including conditions
relating to applicable federal or state securities laws, as it considers
necessary or advisable. An Option which is not intended to be an Incentive Stock
Option (as hereinafter defined) shall be designated a "Nonstatutory Stock
Option".

     (b) Incentive Stock Options. An Option that the Board intends to be an
"incentive stock option" as defined in Section 422 of the Code (an "Incentive
Stock Option") shall only be granted to employees of the Company and shall be
subject to and shall be construed consistently with the requirements of Section
422 of the Code. The Company shall have no liability to a Participant, or any
other party, if an Option (or any part thereof) which is intended to be an
Incentive Stock Option is not an Incentive Stock Option.

     (c) Exercise Price. The Board shall establish the exercise price at the
time each Option is granted and specify it in the applicable option agreement.

     (d) Duration of Options. Each Option shall be exercisable at such times and
subject to such terms and conditions as the Board may specify in the applicable
option agreement.

     (e) Exercise of Option. Options may be exercised by delivery to the Company
of a written notice of exercise signed by the proper person or by any other form
of notice (including

                                      -2-
<PAGE>

electronic notice) approved by the Board together with payment in full as
specified in Section 5(f) for the number of shares for which the Option is
exercised.

     (f) Payment Upon Exercise. Common Stock purchased upon the exercise of an
Option granted under the Plan shall be paid for as follows:

          (1) in cash or by check, payable to the order of the Company;

          (2) except as the Board may, in its sole discretion, otherwise provide
in an option agreement, by (i) delivery of an irrevocable and unconditional
undertaking by a creditworthy broker to deliver promptly to the Company
sufficient funds to pay the exercise price or (ii) delivery by the Participant
to the Company of a copy of irrevocable and unconditional instructions to a
creditworthy broker to deliver promptly to the Company cash or a check
sufficient to pay the exercise price;

          (3) when the Common Stock is registered under the Exchange Act, by
delivery of shares of Common Stock owned by the Participant valued at their fair
market value as determined by (or in a manner approved by) the Board in good
faith ("Fair Market Value"), provided such method of payment is then permitted
under applicable law and (ii) such Common Stock was owned by the Participant at
least six months prior to such delivery;

          (4) to the extent permitted by the Board, in its sole discretion by
(i) delivery of a promissory note of the Participant to the Company on terms
determined by the Board, or (ii) payment of such other lawful consideration as
the Board may determine; or

          (5) by any combination of the above permitted forms of payment.

     (g) Substitute Options. In connection with a merger or consolidation of an
entity with the Company or the acquisition by the Company of property or stock
of an entity, the Board may grant Options in substitution for any options or
other stock or stock-based awards granted by such entity or an affiliate
thereof. Substitute Options may be granted on such terms as the Board deems
appropriate in the circumstances, notwithstanding any limitations on Options
contained in the other sections of this Section 5.

6.  Restricted Stock
    ----------------

     (a) Grants. The Board may grant Awards entitling recipients to acquire
shares of Common Stock, subject to the right of the Company to repurchase all or
part of such shares at their issue price or other stated or formula price (or to
require forfeiture of such shares if issued at no cost) from the recipient in
the event that conditions specified by the Board in the applicable Award are not
satisfied prior to the end of the applicable restriction period or periods
established by the Board for such Award (each, a "Restricted Stock Award").

     (b) Terms and Conditions. The Board shall determine the terms and
conditions of any such Restricted Stock Award, including the conditions for
repurchase (or forfeiture) and the issue price, if any. Any stock certificates
issued in respect of a Restricted Stock Award shall be registered in the name of
the Participant and, unless otherwise determined by the Board,

                                      -3-
<PAGE>

deposited by the Participant, together with a stock power endorsed in blank,
with the Company (or its designee). At the expiration of the applicable
restriction periods, the Company (or such designee) shall deliver the
certificates no longer subject to such restrictions to the Participant or if the
Participant has died, to the beneficiary designated, in a manner determined by
the Board, by a Participant to receive amounts due or exercise rights of the
Participant in the event of the Participant's death (the "Designated
Beneficiary"). In the absence of an effective designation by a Participant,
Designated Beneficiary shall mean the Participant's estate.

7.  Other Stock-Based Awards

     The Board shall have the right to grant other Awards based upon the Common
Stock having such terms and conditions as the Board may determine, including the
grant of shares based upon certain conditions, the grant of securities
convertible into Common Stock and the grant of stock appreciation rights.

8.  Legends.

     The Company may at any time place legends referencing the repurchase right
described in Section 6(a) above and any applicable federal or state securities
law restrictions on all certificates representing shares of restricted stock
subject to the provisions of this Plan.  Participants shall, at the request of
the Company, promptly present to the Company any and all certificates
representing shares acquired pursuant to an Award in the possession of a
Participant in order to effectuate the provisions of this paragraph.  Unless
otherwise specified by the Company, legends placed on such certificates may
include, but shall not be limited to, the following:

     "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A RIGHT OF
     REPURCHASE IN FAVOR OF THE CORPORATION OR ITS ASSIGNEE SET FORTH IN AN
     AGREEMENT BETWEEN THE CORPORATION AND THE REGISTERED HOLDER, OR SUCH
     HOLDER'S PREDECESSOR IN INTEREST, A COPY OF WHICH IS ON FILE AT THE
     PRINCIPAL OFFICE OF THE CORPORATION."


9.  Adjustments for Changes in Common Stock and Certain Other Events

(a)  Changes in Capitalization.  In the event of any stock split, reverse stock
     split, stock dividend, recapitalization, combination of shares,
     reclassification of shares, spin-off or other similar change in
     capitalization or event, or any distribution to holders of Common Stock
     other than a normal cash dividend, (i) the number and class of securities
     available under this Plan, (ii) the per-Participant limit set forth in
     Section 4(b), (iii) the number and class of securities and exercise price
     per share subject to each outstanding Option, (iv) the repurchase price per
     share subject to each outstanding Restricted Stock Award, and (v) the terms
     of each other outstanding Award shall be appropriately adjusted by the
     Company (or substituted Awards may be made, if applicable) to the extent
     the Board shall determine, in good faith, that such an adjustment (or
     substitution) is necessary and appropriate.  If this Section 8(a) applies
     and Section

                                      -4-

<PAGE>

     8(c) also applies to any event, Section 8(c) shall be applicable to such
     event, and this Section 8(a) shall not be applicable.

     (b) Liquidation or Dissolution. In the event of a proposed liquidation or
dissolution of the Company, the Board shall upon written notice to the
Participants provide that all then unexercised Options will (i) become
exercisable in full as of a specified time at least 10 business days prior to
the effective date of such liquidation or dissolution and (ii) terminate
effective upon such liquidation or dissolution, except to the extent exercised
before such effective date. The Board may specify the effect of a liquidation or
dissolution on any Restricted Stock Award or other Award granted under the Plan
at the time of the grant of such Award.

(c)  Acquisition Events

          (1) Definition. An "Acquisition Event" shall mean: (a) any merger or
consolidation of the Company with or into another entity as a result of which
the Common Stock is converted into or exchanged for the right to receive cash,
securities or other property or (b) any exchange of shares of the Company for
cash, securities or other property pursuant to a statutory share exchange
transaction.

          (2) Consequences of an Acquisition Event on Options. Upon the
occurrence of an Acquisition Event, or the execution by the Company of any
agreement with respect to an Acquisition Event, the Board shall provide that all
outstanding Options shall be assumed, or equivalent options shall be
substituted, by the acquiring or succeeding corporation (or an affiliate
thereof). For purposes hereof, an Option shall be considered to be assumed if,
following consummation of the Acquisition Event, the Option confers the right to
purchase, for each share of Common Stock subject to the Option immediately prior
to the consummation of the Acquisition Event, the consideration (whether cash,
securities or other property) received as a result of the Acquisition Event by
holders of Common Stock for each share of Common Stock held immediately prior to
the consummation of the Acquisition Event (and if holders were offered a choice
of consideration, the type of consideration chosen by the holders of a majority
of the outstanding shares of Common Stock); provided, however, that if the
consideration received as a result of the Acquisition Event is not solely common
stock of the acquiring or succeeding corporation (or an affiliate thereof), the
Company may, with the consent of the acquiring or succeeding corporation,
provide for the consideration to be received upon the exercise of Options to
consist solely of common stock of the acquiring or succeeding corporation (or an
affiliate thereof) equivalent in fair market value to the per share
consideration received by holders of outstanding shares of Common Stock as a
result of the Acquisition Event.

     Notwithstanding the foregoing, if the acquiring or succeeding corporation
(or an affiliate thereof) does not agree to assume, or substitute for, such
Options, then the Board shall, upon written notice to the Participants, provide
that all then unexercised Options will become exercisable in full as of a
specified time prior to the Acquisition Event and will terminate immediately
prior to the consummation of such Acquisition Event, except to the extent
exercised by the Participants before the consummation of such Acquisition Event;
provided, however, that in the event of an Acquisition Event under the terms of
which holders of Common Stock will receive upon consummation thereof a cash
payment for each share of Common Stock

                                      -5-

<PAGE>

surrendered pursuant to such Acquisition Event (the "Acquisition Price"), then
the Board may instead provide that all outstanding Options shall terminate upon
consummation of such Acquisition Event and that each Participant shall receive,
in exchange therefor, a cash payment equal to the amount (if any) by which (A)
the Acquisition Price multiplied by the number of shares of Common Stock subject
to such outstanding Options (whether or not then exercisable), exceeds (B) the
aggregate exercise price of such Options.

          (3) Consequences of an Acquisition Event on Restricted Stock Awards.
Upon the occurrence of an Acquisition Event, the repurchase and other rights of
the Company under each outstanding Restricted Stock Award shall inure to the
benefit of the Company's successor and shall apply to the cash, securities or
other property which the Common Stock was converted into or exchanged for
pursuant to such Acquisition Event in the same manner and to the same extent as
they applied to the Common Stock subject to such Restricted Stock Award.

          (4) Consequences of an Acquisition Event on Other Awards. The Board
shall specify the effect of an Acquisition Event on any other Award granted
under the Plan at the time of the grant of such Award.

10.  General Provisions Applicable to Awards

     (a) Transferability of Awards. Except as the Board may otherwise determine
or provide in an Award, Awards shall not be sold, assigned, transferred, pledged
or otherwise encumbered by the person to whom they are granted, either
voluntarily or by operation of law, except by will or the laws of descent and
distribution, and, during the life of the Participant, shall be exercisable only
by the Participant. References to a Participant, to the extent relevant in the
context, shall include references to authorized transferees.

     (b) Documentation. Each Award shall be evidenced by a written instrument in
such form as the Board shall determine. Each Award may contain terms and
conditions in addition to those set forth in the Plan.

     (c) Board Discretion. Except as otherwise provided by the Plan, each Award
may be made alone or in addition or in relation to any other Award. The terms of
each Award need not be identical, and the Board need not treat Participants
uniformly.

     (d) Termination of Status. The Board shall determine the effect on an Award
of the disability, death, retirement, authorized leave of absence or other
change in the employment or other status of a Participant and the extent to
which, and the period during which, the Participant, the Participant's legal
representative, conservator, guardian or Designated Beneficiary may exercise
rights under the Award.

     (e) Withholding. Each Participant shall pay to the Company, or make
provision satisfactory to the Board for payment of, any taxes required by law to
be withheld in connection with Awards to such Participant no later than the date
of the event creating the tax liability. Except as the Board may otherwise
provide in an Award, when the Common Stock is registered under the Exchange Act,
Participants may, to the extent then permitted under applicable law, satisfy
such tax obligations in whole or in part by delivery of shares of Common Stock,
including

                                      -6-

<PAGE>

shares retained from the Award creating the tax obligation, valued at their Fair
Market Value. The Company may, to the extent permitted by law, deduct any such
tax obligations from any payment of any kind otherwise due to a Participant.

     (f) Amendment of Award. The Board may amend, modify or terminate any
outstanding Award, including but not limited to, substituting therefor another
Award of the same or a different type, changing the date of exercise or
realization, and converting an Incentive Stock Option to a Nonstatutory Stock
Option, provided that the Participant's consent to such action shall be required
unless the Board determines that the action, taking into account any related
action, would not materially and adversely affect the Participant.

     (g) Conditions on Delivery of Stock. The Company will not be obligated to
deliver any shares of Common Stock pursuant to the Plan or to remove
restrictions from shares previously delivered under the Plan until (i) all
conditions of the Award have been met or removed to the satisfaction of the
Company, (ii) in the opinion of the Company's counsel, all other legal matters
in connection with the issuance and delivery of such shares have been satisfied,
including any applicable securities laws and any applicable stock exchange or
stock market rules and regulations, and (iii) the Participant has executed and
delivered to the Company such representations or agreements as the Company may
consider appropriate to satisfy the requirements of any applicable laws, rules
or regulations.

     (h) Acceleration. The Board may at any time provide that any Options shall
become immediately exercisable in full or in part, that any Restricted Stock
Awards shall be free of restrictions in full or in part or that any other Awards
may become exercisable in full or in part or free of some or all restrictions or
conditions, or otherwise realizable in full or in part, as the case may be.

     (i) Fractional Shares. The Company shall not be required to issue
fractional shares upon the exercise of an Option or the vesting of an Award.

11.  Miscellaneous

     (a) No Right To Employment or Other Status. No person shall have any claim
or right to be granted an Award, and the grant of an Award shall not be
construed as giving a Participant the right to continued employment or any other
relationship with the Company. The Company expressly reserves the right at any
time to dismiss or otherwise terminate its relationship with a Participant free
from any liability or claim under the Plan, except as expressly provided in the
applicable Award.

     (b) No Rights As Stockholder. Subject to the provisions of the applicable
Award, no Participant or Designated Beneficiary shall have any rights as a
stockholder with respect to any shares of Common Stock to be distributed with
respect to an Award until becoming the record holder of such shares.
Notwithstanding the foregoing, in the event the Company effects a split of the
Common Stock by means of a stock dividend and the exercise price of and the
number of shares subject to such Option are adjusted as of the date of the
distribution of the dividend (rather

                                      -7-

<PAGE>

than as of the record date for such dividend), then an optionee who exercises an
Option between the record date and the distribution date for such stock dividend
shall be entitled to receive, on the distribution date, the stock dividend with
respect to the shares of Common Stock acquired upon such Option exercise,
notwithstanding the fact that such shares were not outstanding as of the close
of business on the record date for such stock dividend.

     (c) Effective Date and Term of Plan. The Plan shall become effective on the
date on which it is adopted by the Board, but no Award granted to a Participant
that is intended to comply with Section 162(m) shall become exercisable, vested
or realizable, as applicable to such Award, unless and until the Plan has been
approved by the Company's stockholders to the extent stockholder approval is
required by Section 162(m) in the manner required under Section 162(m)
(including the vote required under Section 162(m)). No Awards shall be granted
under the Plan after the completion of ten years from the earlier of (i) the
date on which the Plan was adopted by the Board or (ii) the date the Plan was
approved by the Company's stockholders, but Awards previously granted may extend
beyond that date.

     (d) Amendment of Plan. The Board may amend, suspend or terminate the Plan
or any portion thereof at any time, provided that to the extent required by
Section 162(a), no Award granted to a Participant that is intended to comply
with Section 162(m) after the date of such amendment shall become exercisable,
realizable or vested, as applicable to such Award, unless and until such
amendment shall have been approved by the Company's stockholders as required by
Section 162(m) (including the vote required under Section 162(m)).

     (e) Governing Law. The provisions of the Plan and all Awards made hereunder
shall be governed by and interpreted in accordance with the laws of the State of
Delaware, without regard to any applicable conflicts of law.


                    Adopted by the Board on March 22, 2000

                    Approved by the stockholders as of March 31, 2000
