                            THE NETPLEX GROUP, INC.

              Warrant for the Purchase of Shares of Common Stock
              --------------------------------------------------

No. RII-001                                              Up to 15,000 Shares of
Date: May 15, 2000                            Common Stock, $.001 par value

          FOR VALUE RECEIVED, THE NETPLEX GROUP, INC., a New York corporation
(the "Company"), with its principal office at 1800 Robert Fulton Drive, Suite
250, Reston, Virginia 20191, hereby certifies that Roseland II L.L.C., its
assignees, successors and assigns (the "Holder") is entitled, subject to the
provisions of this Warrant, to purchase from the Company, at any time after the
date hereof and continuing for a period of five (5) years (the "Expiration
Date"), up to the number of fully paid and nonassessable shares of Common Stock
of the Company set forth above, subject to adjustment as hereinafter provided.

          The Holder may purchase such number of shares of Common Stock at a
purchase price per share (as appropriately adjusted pursuant to Section 6
hereof) of $7.72 (the "Exercise Price"), subject to the limitations set forth in
Section 1. The term "Common Stock" shall mean the aforementioned Common Stock of
the Company, together with any other equity securities that may be issued by the
Company in addition thereto or in substitution therefor as provided herein.

          The number of shares of Common Stock to be received upon the exercise
or exchange of this Warrant and the price to be paid for a share of Common Stock
are subject to adjustment from time to time as hereinafter set forth. The shares
of Common Stock deliverable upon such exercise or exchange, as adjusted from
time to time, are hereinafter sometimes referred to as "Warrant Shares."

          Section 1. Exercise of Warrant. This Warrant may be exercised in whole
                     -------------------
or in part on any business day on or before the Expiration Date by presentation
and surrender hereof to the Company at its principal office at the address set
forth in the initial paragraph hereof (or at such other

<PAGE>

address as the Company may hereafter notify the Holder in writing) with the
Purchase Form annexed hereto duly executed and accompanied by proper payment of
the Exercise Price in lawful money of the United States of America in the form
of a check, subject to collection, for the number of Warrant Shares specified in
the Purchase Form. If this Warrant should be exercised in part only, the Company
shall, upon surrender of this Warrant, execute and deliver a new Warrant
evidencing the rights of the Holder thereof to purchase the balance of the
Warrant Shares purchasable hereunder. Upon receipt by the Company of this
Warrant and such Purchase Form, together with proper payment of the Exercise
Price, at such office, the Holder shall be deemed to be the holder of record of
the Warrant Shares, notwithstanding that the stock transfer books of the Company
shall then be closed or that certificates representing such Warrant Shares shall
not then be actually delivered to the Holder. The Company shall pay any and all
documentary stamp or similar issue or transfer taxes payable in respect of the
issue or delivery of the Warrant Shares. The Company shall cause the Warrant
Shares to be delivered to the Holder within five (5) days after the receipt of
the Purchase Form and payment of the Exercise Price.

          Section 2.  Reservation of Shares. The Company hereby agrees that at
                      ---------------------
all times there shall be reserved for issuance and delivery upon exercise or
exchange of this Warrant all shares of its Common Stock or other shares of
capital stock of the Company from time to time issuable upon exercise or
exchange of this Warrant. All such shares shall be duly authorized and, when
issued upon the exercise or exchange of the Warrant in accordance with the terms
hereof, shall be validly issued, fully paid and nonassessable, free and clear of
all liens, security interests, charges and other encumbrances or restrictions on
sale (other than any restrictions on sale pursuant to applicable federal and
state securities laws) and free and clear of all preemptive rights.

          Section 3.  Fractional Interest
                      -------------------

          The Company will not issue a fractional share of Common Stock upon
exercise or exchange of this Warrant. Instead, the Company will deliver its
check for the current market value of the fractional share. The current market
value of a fraction of a share is determined as follows: multiply the Market
Price (as defined in Section 6(g) below) of a full share by the fraction of a
share and round the result to the nearest cent.

          Section 4.  Assignment or Loss of Warrant.
                      -----------------------------

          (a)   Except as provided in Section 9, the Holder of this Warrant
shall be entitled, without obtaining the consent of the Company, to assign its
interest in this Warrant, or any of the Warrant Shares, in whole or in part to
any bona fide affiliate, officer, director or partner of Holder, provided,
however, that the transferee, prior to any such transfer, agrees in writing, in
form and substance satisfactory to the Company, to be bound by the terms of this
Agreement as if originally a party hereto and provides the Company with an
opinion of counsel in such form reasonably acceptable to the Company and its
counsel, that such transfer would not be in violation of the Act or any
applicable state securities or blue sky laws. Subject to the provisions hereof
and of Section 9, upon surrender of this Warrant to the Company or at the office
of its stock transfer agent or warrant agent, with the Assignment Form annexed
hereto duly executed and funds sufficient to pay any transfer or other tax
payable in respect thereof, the Company shall, without charge, execute and
deliver a new Warrant or Warrants in the name of the assignee or assignees named
in such instrument of assignment and, if the Holder's entire interest is not
being assigned, in the name of the Holder, and this Warrant shall promptly be
canceled.

                                       2
<PAGE>

          (b)  Upon receipt of evidence satisfactory to the Company of the loss,
theft, destruction or mutilation of this Warrant, and (in the case of loss,
theft or destruction) of indemnification satisfactory to the Company, and upon
surrender and cancellation of this Warrant, if mutilated, the Company shall
execute and deliver a new Warrant of like tenor and date, provided, however,
that Holder shall reimburse the Company for its reasonable costs and expenses to
do so.

          Section 5.   Rights of the Holder.  The Holder shall not, by virtue
                       --------------------
hereof, be entitled to any rights of a shareholder in the Company, either at law
or equity, and the rights of the Holder are limited to those set forth in this
Warrant. Nothing contained in this Warrant shall be construed as conferring upon
the Holder hereof the right to vote or to consent or to receive notice as a
shareholder of the Company on any matters or with respect to any rights
whatsoever as a shareholder of the Company. No dividends or interest shall be
payable or accrued in respect of this Warrant or the interest represented hereby
or the Warrant Shares purchasable hereunder until, and only to the extent that,
this Warrant shall have been exercised or exchanged in accordance with its
terms.

          Section 6.   Adjustment of Exercise Price and Number of Shares. The
                       -------------------------------------------------
number and kind of securities purchasable upon the exercise or exchange of this
Warrant and the Exercise Price shall be subject to adjustment from time to time
upon the occurrence of certain events, as follows:

          (a)     Adjustment for Change in Capital Stock. If at any time after
                  --------------------------------------
May 15, 2000, the Company:

                  (A)  pays a dividend or makes a distribution on its Common
                       Stock, in either case in shares of its Common Stock;

                  (B)  subdivides its outstanding shares of Common Stock into a
                       greater number of shares;

                  (C)  combines its outstanding shares of Common Stock into a
                       smaller number of shares; or

                  (D)  makes a distribution on its Common Stock either in
                       property or in shares of its capital stock other than
                       Common Stock;

then the Exercise Price in effect immediately prior to such action shall be
adjusted so that the Holder may receive, upon exercise or exchange of this
Warrant and payment of the same aggregate consideration, the number of shares of
capital stock or other property of the Company which the Holder would have owned
immediately following such action if the Holder had exercised or exchanged the
Warrant immediately prior to such action.

          The adjustment shall become effective immediately after the record
date in the case of a dividend or distribution and immediately after the
effective date in the case of a subdivision, combination or reclassification.

          This subsection does not apply to cash dividends or cash distributions
paid out of consolidated current or retained earnings as shown on the books of
the Company and paid in the ordinary course of business.

                                       3

<PAGE>

     (b)  Deferral of Issuance of Payment.  In any case in which an event
          -------------------------------
covered by this Section 6 shall require that an adjustment in the Exercise Price
be made effective as of a record date, the Company may elect to defer until the
actual occurrence of such event (i) issuing to the Holder, if this Warrant is
exercised after such record date, the shares of Common Stock and other capital
stock of the Company, if any, issuable upon such exercise over and above the
shares of Common Stock or other capital stock of the Company, if any, issuable
upon such exercise on the basis of the Exercise Price in effect prior to such
adjustment, and (ii) paying to the Holder by check any amount in lieu of the
issuance of fractional shares pursuant to Section 3.

     (c)  When No Adjustment Required.  No adjustment need be made for a change
          ---------------------------
in the par value of the Common Stock.

     (d)  Market Price.  The "Market Price" per share of Common Stock is the
          ------------
last reported sales price of the Common Stock as reported by NASDAQ, or the
primary national securities exchange on which the Common Stock is then quoted;
provided, however, that if quotes for the Common Stock are not reported by
NASDAQ and the Common Stock is neither traded on the NASDAQ National Marker, on
a national securities exchange, on the NASDAQ Small Cap Market nor on the OTC
Electronic Bulletin Board, the price referred to above shall be the price
reflected in the over-the-counter market as reported by the National Quotation
Bureau, Inc. or any organization performing a similar function, and provided,
further, that if the Common Stock is not then publicly traded, the Market Price
shall equal the Conversion Price.

     (e)  No Adjustment Upon Exercise of Warrants.  No adjustments shall be made
          ---------------------------------------
under any Section herein in connection with the issuance of Warrant Shares upon
exercise or exchange of the Warrants.

     (f)  Common Stock Defined.  Whenever reference is made in Section 6(a) to
          --------------------
the issue of shares of Common Stock, the term "Common Stock" shall include any
equity securities of any class of the Company hereinafter authorized which shall
not be limited to a fixed sum or percentage in respect of the right of the
thereof to participate in dividends or distributions of assets upon the
voluntary or involuntary liquidation, dissolution or winding up of the Company.
Subject to the provisions of Section 8 hereof, however, shares issuable upon
exercise or exchange hereof shall include only shares of the class designated as
Common Stock of the Company as of the date hereof or shares of any class or
classes resulting from any reclassification or reclassifications thereof or as a
result of any corporate reorganization as provided for in Section 8 hereof.

     Section 7.  Officers' Certificate.  Whenever the Exercise Price shall be
                 ---------------------
adjusted as required by the provisions of Section 6, the Company shall forthwith
file in the custody of its secretary or an assistant secretary at its principal
office an officers' certificate showing the adjusted Exercise Price determined
as herein provided, setting forth in reasonable detail the facts requiring such
adjustment and the manner of computing such adjustment. Each such officers'
certificate shall be signed by the chairman, president or chief financial
officer of the Company and by the secretary or any assistant secretary of the
Company. Each such Officers' certificate shall be made available at all
reasonable times for inspection by the Holder or any holder of a Warrant
executed and delivered pursuant to Section 4 hereof.

                                       4

<PAGE>

          Section 8. Reclassification, Reorganization, Consolidation or Merger.
                     ---------------------------------------------------------
In the event of any reclassification, capital reorganization or other change of
outstanding shares of Common Stock of the Company (other than a subdivision or
combination of the outstanding Common Stock and other than a change in the par
value of the Common Stock) or in the event of any consolidation or merger of the
Company with or into another corporation (other than a merger in which merger
the Company is the continuing corporation and that does not result in any
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the class issuable upon exercise or exchange of this Warrant)
or in the event of any sale, lease, transfer or conveyance to another
corporation of the property and assets of the Company as an entirety or
substantially as an entirety, the Company shall use its best efforts to cause
effective provisions to be made so that the Holder shall have the right
thereafter, by exercising this Warrant, to purchase the kind and amount of
shares of stock and other securities and property (including cash) receivable
upon such reclassification, capital reorganization and other change,
consolidation, merger, sale or conveyance by a holder of the number of shares of
Common Stock that would have been received upon exercise or exchange of this
Warrant immediately prior to such reclassification, capital reorganization,
change, consolidation, merger, sale or conveyance. Any such provision shall
include provisions for adjustments in respect of such shares of stock and other
securities and property that shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Warrant. The foregoing provisions of
this Section 8 shall similarly apply to successive reclassifications, capital
reorganizations and changes of shares of Common Stock and to successive
consolidations, mergers, sales or conveyances.

          Section 9. Transfer to Comply with the Securities Act of 1933;
                     ---------------------------------------------------
Registration Rights.
-------------------

          9.1 No sale, transfer, assignment, hypothecation or other disposition
of this Warrant or of the Warrant Shares shall be made unless any such transfer,
assignment or other disposition will comply with the rules and statutes
administered by the Securities and Exchange Commission and (i) a Registration
Statement under the Act including such Shares is currently in effect, or (ii) in
the written opinion of counsel, which counsel and which opinion shall be
reasonably satisfactory to the Company, a current registration Statement is not
required for such disposition of the shares. Each stock certificate representing
Warrant Shares issued upon exercise or exchange of this Warrant shall bear a
legend in substantially the following form (unless, in the opinion of counsel,
which counsel and which opinion shall be reasonably satisfactory to the Company,
such legend is not required):

          "THE SECURITIES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED
          UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "ACT"), OR
          UNDER THE SECURITIES LAWS OF ANY STATE. THESE SECURITIES ARE
          SUBJECT TO RESTRICTIONS ON TRANSFERABILITY AND RESALE AND MAY
          NOT BE TRANSFERRED OR RESOLD EXCEPT AS PERMITTED UNDER THE
          ACT AND THE APPLICABLE STATE SECURITIES LAWS, PURSUANT TO
          REGISTRATION OR EXEMPTION THEREFROM. THE ISSUER OF THESE
          SECURITIES MAY REQUIRE AN OPINION OF COUNSEL IN FORM AND
          SUBSTANCE SATISFACTORY TO THE ISSUER TO THE EFFECT THAT ANY
          PROPOSED TRANSFER OR RESALE IS IN COMPLIANCE WITH THE ACT AND
          ANY APPLICABLE STATE SECURITIES LAWS."

                                       5

<PAGE>

     9.2  The Company agrees that during the term of this Warrant, the Company
shall register the Warrant Shares with any subsequent registration statement
filed by the Company.  Holder acknowledges that, in the event a transfer of the
Warrant occurs subsequent to the Company's registration of the Warrant Shares,
the registration of the Warrant Shares may not be effective as to the transferee
of this Warrant.  In such event, the Company agrees to file a post-effective
amendment to such registration statement, or take such other reasonable action,
which in the Company's sole discretion, may be required to make such
registration effective as to the transferee, provided the Holder reimburses the
Company for its costs and expenses, including reasonable attorneys fees, to
effectuate the registration.

     Section 10.  Modification and Waiver.  Except as otherwise provided herein,
                  -----------------------
any term of this Warrant may be amended, and the observance of any term of this
Warrant may be waived (either generally or in a particular instance, either
retroactively or prospectively, and either for a specified period of time or
indefinitely), with the written consent of the Company and the Holder of this
Warrant.  Any amendment or waiver effected in accordance with this section shall
be binding upon each future Holder of this Warrant and the Company.

     Section 11.  Notices.  All notices and other communications required or
                  -------
permitted hereunder shall be in writing and shall be deemed effectively given
upon personal delivery, on the first business day following mailing by overnight
courier, or on the fifth day following mailing by registered or certified mail,
return receipt requested, postage prepaid, addressed to the Company at the
address indicated therefor in the first paragraph of this Warrant and the Holder
at its address as shown on the books of the Company; provided, however, that
presentation of a Purchase Form and payment of any Exercise Price shall be
effective only upon receipt by the Company.

     Section 12.  Description Headings and Governing Law.  The titles of the
                  --------------------------------------
paragraphs and subparagraphs of this Warrant are for convenience of reference
only and are not to be considered in construing this Warrant. This Warrant shall
be governed by and construed under the laws of the State of New York without
regard to any otherwise applicable principles of conflicts of laws.

     Section 13.  Entire Agreement.  This Warrant and the other documents
                  ----------------
delivered pursuant hereto constitute the full and entire understanding and
agreement among the parties with regard to the subjects hereof and no party
shall be liable or bound to any other party in any manner by any
representations, warranties, convenants or agreements except as specifically set
forth herein or therein.  Nothing in this Warrant, express or implied, is
intended to confer upon any party, other than the parties hereto and their
respective successors and assigns, any rights, remedies, obligations, or
liabilities under or by reason of this Warrant, except as expressly provided
herein.

     Section 14.  Severability.  In the event that any provision of this Warrant
                  ------------
shall be invalid, illegal or unenforceable, it shall, to the extent practicable,
be modified so as to make it valid, legal and enforceable and to retain as
nearly as practicable the intent of the parties, and the validity, legality, and
enforceability of the remaining provisions shall not in any way be affected or
impaired thereby.  To the extent permitted by law, the parties hereto waive the
benefit of any provision of law that renders any provision of this Warrant
invalid or unenforceable in any respect.

     Section 15.  No Waiver.  No waiver by any party to this Warrant of any one
                  ---------
or more defaults by any other party or parties in the performance of any of the
provisions hereof shall operate or be construed as a waiver of any future
default or defaults, whether of a like or different

                                       6

<PAGE>

nature. Except as expressly provided herein, no failure or delay on the part of
any party in exercising any right, power or remedy hereunder shall operate as a
waiver thereof, nor shall any single or partial exercise of any such right,
power or remedy preclude any other or further exercise thereof or the exercise
of any other right, power or remedy.

          IN WITNESS WHEREOF, the Company has duly caused this Warrant to be
signed by its duly authorized officer and to be dated as of this 15th day of
May, 2000.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY STATE SECURITIES LAWS AND MAY
NOT BE SOLD, PLEDGED, OR OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION
THEREOF UNDER SUCH ACT AND SUCH LAWS OR AN OPINION OF COUNSEL REASONABLY
SATISFACTORY TO THE CORPORATION AND ITS COUNSEL, THAT SUCH REGISTRATION IS NOT
REQUIRED.

                           WARRANT TO PURCHASE STOCK

Corporation: The NetPlex Group, Inc.
Number of Shares: 75,000
Class of Stock: Common
Initial Exercise Price: $6.00
Issue Date: July 31, 2000
Expiration Date: July 31, 2005

     THIS WARRANT CERTIFIES THAT, for the agreed upon value of $1.00 and for
other good and valuable consideration, SILICON VALLEY BANK ("Holder") is
entitled to purchase the number of fully paid and nonassessable shares of the
class of securities (the "Shares") of the corporation (the "Company") at the
initial exercise price per Share (the "Warrant Price") all as set forth above
and as adjusted pursuant to Article 2 of this Warrant, subject to the provisions
and upon the terms and conditions set forth in this Warrant.

ARTICLE 1.  EXERCISE.
            --------

            1.1  Method of Exercise. Holder may exercise this Warrant by
                 ------------------
delivering a duly executed Notice of Exercise in substantially the form attached
as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

            1.2  Conversion Right. In lieu of exercising this Warrant as
                 ----------------
specified in Section 1.1, Holder may from time to time convert this Warrant, in
whole or in part, into a number of Shares determined by dividing (a) the
aggregate fair market value of the Shares or other securities otherwise issuable
upon exercise of this Warrant (whether exercised in whole or in part) minus the
aggregate Warrant Price of such Shares by (b) the fair market value of one
Share. The fair market value of the Shares shall be determined pursuant to
Section 1.4.

            1.3  Intentionally Omitted
                 ---------------------

            1.4  Fair Market Value. If the Shares are traded in a public market,
                 -----------------
the fair market value of the Shares shall be the closing price of the Shares (or
the closing price of the

<PAGE>

Company's stock into which the Shares are convertible) reported for the business

the Shares are not traded in a public market, the Board of Directors of the
Company shall determine fair market value in its reasonable good faith judgment.
The foregoing notwithstanding, if Holder advises the Board of Directors in
writing that Holder disagrees with such determination, then the Company and
Holder shall promptly agree upon a reputable investment banking firm to
undertake such valuation. If the valuation of such investment banking firm is
greater than that determined by the Board of Directors, then all fees and
expenses of such investment banking firm shall be paid by the Company. In all
other circumstances, such fees and expenses shall be paid by Holder.

new warrant of like tenor.

            1.7  Repurchase on Sale, Merger, or Consolidation of the Company.
                 -----------------------------------------------------------

                 1.7.1.  "Acquisition". For the purpose of this Warrant,
                          -----------
"Acquisition" means any sale, license, or other disposition of all or
substantially all of the assets of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

record date for the Acquisition and subsequent closing. The Warrant Price shall
be adjusted accordingly.

ARTICLE 2.  ADJUSTMENTS TO THE SHARES.
            -------------------------

            2.1  Stock Dividends, Splits, Etc. If the Company declares or pays a
                 ----------------------------
dividend on its common stock (or the Shares if the Shares are securities other
than common stock) payable in common stock, or other securities, subdivides the
outstanding common stock into a greater amount of common stock, or, if the
Shares are securities other than common stock, subdivides the Shares in a
transaction that increases the amount of common stock into which the Shares are
convertible, then upon exercise of this Warrant, for each Share acquired, Holder
shall receive,

                                       2
<PAGE>

without cost to Holder, the total number and kind of securities to which Holder
would have been entitled had Holder owned the Shares of record as of the date
the dividend or subdivision occurred.

          2.2  Reclassification, Exchange or Substitution. Upon any
               ------------------------------------------
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this Warrant, Holder shall be entitled to receive, upon exercise
or conversion of this Warrant, the number and kind of securities and property
that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. The Company or its successor shall promptly issue to Holder a new
Warrant for such new securities or other property. The new Warrant shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property
issuable upon exercise of the new Warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, substitutions,
or other events.

          2.3  Adjustments for Combinations, Etc.  If the outstanding shares are
               ---------------------------------
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased and the number
of Shares issuable upon exercise of this Warrant shall be proportionately
decreased.

          2.4  Adjustments for Diluting Issuances. The Warrant Price and the
               ----------------------------------
number of Shares issuable upon exercise of this Warrant or, if the Shares are
Preferred Stock, the number of shares of common stock issuable upon conversion
of the Shares, shall be subject to adjustment, from time to time in the manner
set forth on Exhibit A in the event of Diluting Issuances (as defined on Exhibit
A).

          2.5  No Impairment. The Company shall not, by amendment of its
               -------------
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this Warrant by the Company, but
shall at all times in good faith assist in carrying out of all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment. If the Company
takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this Warrant, the
Warrant Price shall be adjusted downward and the number of Shares issuable upon
exercise of this Warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this Warrant is unchanged.

          2.6  Fractional Shares. No fractional Shares shall be issuable upon
               -----------------
exercise or conversion of the Warrant and the number of Shares to be issued
shall be rounded down to the

                                       3
<PAGE>

nearest whole Share. If a fractional share interest arises upon any exercise or
conversion of the Warrant, the Company shall eliminate such fractional share
interest by paying Holder an amount computed by multiplying the fractional
interest by the fair market value of a full Share.

            2.7  Certificate as to Adjustments. Upon each adjustment of the
                 -----------------------------
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial Officer
setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting
forth the Warrant Price in effect upon the date thereof and the series of
adjustments leading to such Warrant Price.
