            SERIES A CUMULATIVE CONVERTIBLE PREFERRED STOCK PURCHASE AGREEMENT
(this "Agreement") dated as of [        ], 1999, among MONSTERDAATA.COM, INC., a
Delaware corporation (the "Company"), and the several PURCHASERS named in
Exhibit A (individually a "Purchaser" and collectively, the "Purchasers").

            The Company desires to issue and sell to Purchasers, and Purchasers
desire to purchase from the Company, shares (the "Preferred Shares") of Series A
Convertible Preferred Stock, par value $.01 per share, of the Company (the

forth in the Certificate of Designations of the Company (the "Certificate of
Designations") in the identical form and substance of Exhibit B, upon and
subject to the terms and conditions of this Agreement.

            Pursuant to the terms of the Certificate of Designations, the
Preferred Shares will be convertible into shares ("Common Shares") of common
stock, par value $.01 per share, of the Company ("Common Stock"). Unless the
context otherwise requires, the term Common Shares shall be deemed to include
any shares of Common Stock issued or issuable upon conversion of Preferred
Shares (the "Conversion Shares").

            Accordingly, in consideration of the premises and the mutual

(allocated among the Purchasers as set forth on Exhibit A). The Company may
issue and sell to the Purchasers fractional Preferred Shares.

            Section 2. Closing. The closing (the "Closing") of the purchase and
sale of the Preferred Shares shall take place immediately upon the fulfillment
(or waiver) of the conditions precedent set forth in Sections 3 and 4. The date
of the Closing is referred to as the "Closing Date." On or as soon as possible
following the Closing Date, the Company shall issue to each Purchaser stock
certificates representing the Preferred Shares in accordance with the allocation
on Exhibit A, against payment of each Purchaser's Aggregate Purchase Price. All
checks delivered to the Company by Purchasers on or prior to the date hereof for
the Aggregate Purchase Price will be deposited by the Company in escrow and held
in trust until the stock certificates for the Preferred Shares are delivered to
Purchasers. The Preferred Shares shall be registered in Purchasers' names or the
names of the nominees of Purchasers in such denominations as Purchasers shall
request pursuant to instructions delivered to the Company not more than two
business days after the date hereof.

                                                                               2

            5.4 Certain Risks. Such Purchaser recognizes that the purchase of

execution and delivery by such Purchaser of this Agreement and the consummation
of the transactions contemplated hereby have been duly authorized by all
necessary corporate or partnership, as the

            5.10 No Conflicts. No court or governmental injunction, order or
decree affecting such Purchaser and prohibiting the execution and delivery by
such Purchaser of this Agreement and the consummation of the transactions
contemplated hereby is in effect and no provision of the Certificate or Articles
of Incorporation or by-laws (or comparable charter, partnership or other
organizational documents) of such Purchaser, will conflict with, or result in a
material breach or violation of, any of the terms or provisions of, or
constitute (with due notice or lapse of time or both) a material default under,
any material lease, loan agreement, mortgage, security agreement, trust
indenture or other agreement or instrument to which such Purchaser is a party or
by which it is bound or to which any of its material properties or assets is
subject, nor result in the creation or imposition of any lien upon any of the
material properties or assets of such Purchaser.

            5.11 Consents, Approvals, etc. No material consent, approval,
license, permit, order or authorization of, or registration, declaration or

perform its obligations under this Agreement or the Preferred Shares (a
"Material Adverse Effect").

                                                                               5

            Section 7. Registration of Common Stock.

            7.1. Registrable Securities. For the purposes of this Agreement,
"Registrable Securities" shall mean shares of Common Stock issued or issuable
upon the conversion of Preferred Shares or the exercise of any warrants held by
a Purchaser (other than the warrants described in Section 6.2(iii) above);
provided that (i) any such shares of Common Stock shall cease to be Registrable
Securities, and (ii) the Company shall not be obligated to maintain the
effectiveness of the Shelf Registration Statement (as defined below), and the
Company's obligations under this Section 7 shall cease, with respect to a
holder's (a "Holder") Registrable Securities on the first anniversary of the
Closing Date. The period of time during which the Company is required to keep
the Shelf Registration Statement effective is referred to herein as the
"Registration Period."

                                                                               6


            7.2 Registration (a) The Company will as soon as practicable
following the date hereof, but no later than December 15, 1999 (the "Filing
Period"), file with the SEC a shelf registration statement on Form SB-2 or
successor form or such other form as shall be selected by the Company that is
available to it under the Securities Act (the "Shelf Registration Statement")
with respect to the Registrable Securities beneficially owned by Purchasers
following the Closing. If permitted by the SEC's rules, the Company shall be
entitled to amend the Shelf Registration Statement from time to time to register
securities other than Registrable Securities for sale for the account of any
person or entity.

            (b) The Filing Period and the Effectiveness Period (as defined
below) shall be extended by the number of days that (i) any delay is due to the
failure of a Holder to reasonably cooperate in providing to the Company such
information as shall be reasonably requested by the Company in writing for use
in connection with the Shelf Registration Statement and (ii) the SEC does not
provide comments to the Company (or declare the Shelf Registration Statement
effective) within (A) 25 days after the initial filing of the Shelf Registration
Statement or (B) seven days after the filing of any pre-effective amendment to
the Shelf Registration Statement.

            7.3. Registration Procedures. In connection with the registration of
any Registrable Securities under the Securities Act as provided in this Section
7, the Company will use its reasonable best efforts:

            (a) To cause the Shelf Registration Statement to become effective as
soon as practicable following the filing thereof within 45 days after the
Closing Date (the "Effectiveness Period"); provided that if the Shelf
Registration Statement is not declared effective by the SEC by the end of the
Effectiveness Period (as it may be extended pursuant to Section 7.2(b)), then
the exercise price of any warrants for Registrable Securities will be reduced by
5% for each 30-day period that Shelf Registration Statement is not declared
effective by the SEC after such Effectiveness Date.

            (b) Prepare and file with the SEC such amendments and supplements to
such Shelf Registration Statement and the prospectus used in connection
therewith and take all other actions as may be necessary to keep such Shelf
Registration Statement continuously effective until the disposition of all
securities in accordance with the intended methods of disposition by the seller
or sellers thereof set forth in such Shelf Registration Statement shall be
completed, and to comply with the provisions of the Securities Act (to the
extent applicable to the Company) with respect to such dispositions;

            (c) Furnish to each seller of such Registrable Securities such
reasonable number of copies of such Shelf Registration Statement and of each
such amendment and supplement thereto, such reasonable number of copies of the
prospectus included in such Shelf Registration Statement (including each
preliminary prospectus), in conformity with the requirements of the Securities
Act, and such other documents (including exhibits to any of the foregoing), as
such seller may reasonably request (not to exceed 10 copies per seller), in
order to facilitate the disposition of the Registrable Securities owned by such
seller;

                                                                               7


            (d) To register or qualify such Registrable Securities covered by
such Shelf Registration Statement under such other securities or blue sky laws
of such jurisdictions as any seller reasonably requests, except that the Company
will not for any such purpose be required to qualify generally to do business as
a foreign corporation in any jurisdiction wherein it would not, but for the
requirements of this Section 7.3(d) be obligated to be qualified, to subject
itself to taxation in any such jurisdiction, or to consent to general service of
process in any such jurisdiction;

            (e) With a view to making available to the Holders the benefits of
certain rules and regulations of the SEC which at any time permit the sale of
the Registrable Securities to the public without registration, commencing on the
date hereof, the Company agrees to use its reasonable best efforts to:

                  (i) file with the SEC in a timely manner all reports and other
            documents required of the Company under the Exchange Act; and

                  (ii) so long as a Holder owns any unregistered Registrable
            Securities, furnish to such Holder upon any reasonable request a
            written statement by the Company as to its compliance with the
            public information requirements of Rule 144 under the Securities
            Act, and of the Exchange Act, a copy of the most recent annual or
            quarterly report of the Company, and such other reports and
            documents of the Company as such Holder may reasonably request in
            availing itself of any rule or regulation of the SEC allowing a
            Holder to sell any such securities without registration (excluding
            any such reports or documents of the Company which the Company, in
            its sole discretion, shall deem confidential).

            7.4 Registration and Selling Expenses. All expenses incurred by the
Company in connection with the Company's performance of or compliance with this
Section 7, including, without limitation, (i) all registration and filing fees,
(ii) blue sky fees and expenses and (iii) all fees and disbursements of counsel
and accountants retained on behalf of the Company (all such expenses being
called "Registration Expenses"), will be paid by the Company.

            7.5 No Delay. The Holders shall have no right to take any action to
restrain, enjoin or otherwise delay any registration pursuant to Section 7.2
hereof as a result of any dispute, controversy or other matter that may arise
with respect to the interpretation or implementation of this Agreement.

            7.6 Certain Obligations of Holders. (a) Each Holder agrees that,
upon receipt of any written notice from the Company of the happening of any
event requiring the preparation of a supplement or amendment to the Shelf
Registration Statement so that, as thereafter delivered to the Holders, such
prospectus will not contain an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading, each Holder will forthwith discontinue
disposition of Registrable Securities pursuant to the Shelf Registration
Statement until its receipt of copies of

                                                                               8


the supplemented or amended effective prospectus from the Company and, if so
directed by the Company, each Holder shall deliver to the Company all copies,
other than permanent file copies then in such Holder's possession, of the
prospectus covering such Registrable Securities current at the time of receipt
of such notice.

            (b) As a condition to the inclusion of its Registrable Securities,
each Holder shall furnish to the Company such information regarding such Holder
and the intended method of distribution of such securities as the Company may
from time to time request or as shall be required in connection with any
registration, qualification or compliance referred to in this Section 7. Each
such Holder promptly shall furnish to the Company all information required to be
disclosed in order to make the information previously furnished to the Company
not materially misleading.

            (c) Each Holder hereby covenants with the Company (1) not to make
any sale of the Registrable Securities without effectively causing the
prospectus delivery requirements under the Act to be satisfied, and (2) if such
Registrable Securities are to be sold by any method or in any transaction other
than in the over-the-counter market, in privately negotiated transactions, or in
a combination of such methods, to notify the Company at least five business days
prior to the date on which the Holder first offers to sell any such Registrable
Securities.

            (d) Each Holder acknowledges and agrees that the Registrable
Securities sold pursuant to the Shelf Registration Statement are not
transferable on the books of the Company unless the stock certificate submitted
to the transfer agent evidencing such Registrable Securities is accompanied by a
certificate reasonably satisfactory to the Company to the effect that (A) the
Registrable Securities have been sold in accordance with such Shelf Registration
Statement and (B) the requirement of delivering a current prospectus has been
satisfied.

            (e) Each Holder has been hereby advised that the anti-manipulation
provisions of Regulation M under the Exchange Act may apply to sales of the
Registrable Securities offered pursuant to the Shelf Registration Statement, and
agrees not to take any action with respect to any distribution deemed to be made
pursuant to such Shelf Registration Statement, that constitutes a violation of
Regulation M under the Exchange Act or any other applicable rule, regulation or
law.

            (f) At the end of the Registration Period, the Holders of
Registrable Securities included in the Shelf Registration Statement shall
discontinue sales of shares pursuant to such registration statement upon receipt
of notice from the Company of its intention to remove from registration the
shares covered thereby which remain unsold, and such Holders promptly shall
notify the Company of the number of shares registered which remain unsold
immediately upon receipt of such notice from the Company.

            (g) The rights of a Holder with respect to Registrable Securities
shall not be assignable or transferable to any other person or entity other than
an affiliate of the Holder, and any attempted transfer shall cause all rights of
such Holder therein to be forfeited, void ab initio and of no further force and
effect.

                                                                               9


            (h) With the written consent of the Company and the Holders holding
at least majority of the Registrable Securities that are then outstanding, any
provision of this Section 7 may be waived (either generally or in a particular
instance, either retroactively or prospectively and either for a specified
period of time or indefinitely) or amended.

            7.7 Indemnification. (a) The Company shall indemnify, to the extent
permitted by law, each Holder of Registrable Securities against all losses,
claims, damages, liabilities and expenses (or action in respect thereof)
including any of the foregoing incurred in settlement of any litigation, based
on any untrue statement of a material fact or material omission contained in any
registration statement or prospectus (or any amendment or supplement thereto) or
any preliminary prospectus, which registration statement, prospectus or
preliminary prospectus shall be prepared in connection with the registration
contemplated by this Section 7, and will reimburse such Holder and each
controlling person for reasonable legal and other expenses incurred in
connection with defending any such claim, loss, damage, liability or action as
incurred, except insofar as such losses, claims, damages, liabilities or
expenses are caused by any untrue statement or omission made in reliance upon
and in conformity with written information furnished by such Holder and stated
to be specifically for use in the preparation of such registration statement or
prospectus; provided, however, that the Company will not be liable pursuant to
this Section 7.7 if such losses, claims, damages, liabilities or expenses have
been caused by (i) any selling security holder's failure to deliver a copy of
the Shelf Registration Statement or prospectus, or any amendments or supplements
thereto or at or prior to the time such furnishing is required by the Securities
Act; (ii) the failure by such Holder to discontinue disposition of Registrable
Securities pursuant to the Shelf Registration Statement upon a written request
or notice from the Company in accordance with Section 7.6(a); or (iii) any other
violation of any federal or state securities laws or this Agreement by such
Holder.

            (b) In connection with any registration statement in which a Holder
of Registrable Securities is participating, each such Holder shall furnish to
the Company in writing such information as is reasonably requested by the
Company for use in any such registration statement or prospectus and shall
severally, but not jointly, indemnify, to the extent permitted by law, the
Company, its directors and officers and each person or entity, if any, who
controls the Company within the meaning of the Securities Act, against any
losses, claims, damages, liabilities and expenses resulting from any untrue
statement or alleged untrue statement of a material fact or any omission or
alleged omission of a material fact required to be stated in the registration
statement or prospectus or any amendment thereof or supplement thereto or
necessary to make the statements therein not misleading, but only to the extent
such losses, claims, damages, liabilities or expenses are caused by an untrue
statement or alleged untrue statement or by an omission or alleged omission and
made in conformity with such written information so furnished by such Holder;
provided that, the indemnity shall not apply to the extent that such loss,
claim, damage, liability or expense is based upon the fact that a copy of the
registration statement or prospectus or amendment thereof was not delivered to
the Holder at or prior to the time such registration statement or prospectus or
amendment thereof is required to be delivered by the Holder to the applicable
purchaser. If the offering pursuant to any such registration is made through
underwriters, each such Holder agrees to enter into an underwriting

                                                                              10


agreement in customary form with such underwriters and to indemnify such
underwriters, their officers and directors, if any, and each person or entity
who controls such underwriters within the meaning of the Securities Act to the
same extent as hereinabove provided with respect to indemnification by such
Holder.

            (c) Promptly after receipt by an indemnified party under Section 7.7
(a) or (b) of notice of any claim as to which indemnity may be sought,
including, without limitation, the commencement of any action or proceeding,
such indemnified party will, if a claim in respect thereof may be made against
the indemnifying party under such Section, promptly notify the indemnifying
party in writing of the commencement thereof; provided that, the failure of the
indemnified party so to notify the indemnifying party will not relieve the
indemnifying party from its obligations under such Section except to the extent
that the indemnified party is adversely affected by such failure. In case any
such action or proceeding is brought against any indemnified party, and it
notifies the indemnifying party of the commencement thereof, the indemnifying
party and its counsel will conduct the defense of any such action with counsel
approved by such indemnified party (which approval shall not be withheld or
delayed unreasonably) although the indemnified party will be entitled to
participate therein. Notwithstanding the above, the indemnified party will have
the right to employ counsel of its own choice in any such action or proceeding
(and be reimbursed by the indemnifying party for the reasonable fees and
expenses of such counsel) if representation of such indemnified party by the
counsel retained by the indemnifying party would be inappropriate due to
conflicts between the indemnified party and any other party represented by such
counsel in such action or proceeding; provided, however, that the indemnifying
party shall not in connection with any one such action or proceeding or separate
but substantially similar actions or proceedings arising out of the same general
allegations, be liable for the reasonable fees and expenses of more than one
separate firm of attorneys at any time for all indemnified parties, except to
the extent that local counsel, in addition to regular counsel, is required in
order to effectively defend against such action or proceeding. An indemnifying
party will not be liable to any indemnified party for any settlement or entry of
judgment concerning any such action or proceeding effected without the consent
of such indemnifying party.

            (d) If the indemnification provided for in Section 7.7(a) or (b) is
held by a court of competent jurisdiction to be unavailable under applicable law
to an indemnified party in respect of any losses, claims, damages or liabilities
referred to therein, then each applicable indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claims, damages or
liabilities in such proportion as is appropriate to reflect the relative fault
of the Company on the one hand and of the indemnified party on the other in
connection with the statements or omissions which resulted in such losses,
claims, damages, or liabilities, as well as any other relevant equitable
considerations including the relative benefits to such parties. The relative
fault of the Company on the one hand and of the indemnified party on the other
shall be determined by reference to, among other things, whether the untrue or
alleged untrue statement of a material fact or the omission to state a material
fact relates to information supplied by the Company or by the indemnified party
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission. The amount paid or
payable by a

                                                                              11


party as a result of the losses, claims, damages and liabilities referred to
above shall be deemed to include, subject to the limitations set forth in
Section 7.7(c), any legal or other fees or expenses reasonably incurred by such
party in connection with investigating or defending any action or claim. No
person or entity guilty of fraudulent misrepresentation (within the meaning of
Section 11(f) of the Securities Act) will be entitled to contribution from any
person or entity that is not guilty of such fraudulent misrepresentation.

            Section 8. Limitations on Purchasers' Ownership. No Purchaser nor
any of its affiliates (as such term is defined in Rule 12b-2 under the Exchange
Act) shall directly or indirectly without the prior written consent of the Board
of Directors of the Company acquire beneficial ownership within the meaning of
Rule 13d-3 of the Exchange Act (except by way of stock splits, stock dividends
or similar events affecting holders of securities of the Company generally) if
the effect of the acquisition would be to increase the aggregate voting power in
the election of Directors of the Company's Board of Directors of all securities
of the Company owned by such Purchaser and such affiliates to more than 15% of
the total combined voting power of all securities of the Company then
outstanding.

            9.2 Successors and Assigns. This Agreement shall be binding upon and
inure to the benefit of the parties hereto and to their respective heirs, legal
representatives, successors and assigns.

            9.3 Entire Agreement; Survival of Representations and Warranties.
This Agreement sets forth the entire agreement and understanding among the
parties as to the subject matter hereof and merges and supersedes all prior
discussions, agreements and understandings of any and every nature among them.
This Agreement may be amended only by mutual written agreement of the Company
and the Purchasers, and the Company may take any action herein prohibited or
omit to take any action herein required to be performed by it, and any breach of
any covenant, agreement, warranty or representation may be waived, only if the
Company has obtained the written consent or waiver of the Purchasers. The
representations and warranties of the Company set forth in this Agreement shall
survive the Closing Date for 18 months notwithstanding any earlier delivery and
conversion of Preferred Shares except that the representations and warranties
set forth in Sections 6.2 and 6.3 shall survive such 18 months period
indefinitely.

            9.4 Governing Law; Consent to Jurisdiction; etc. (a) Notwithstanding
the place where this Agreement may be executed by any of the parties hereto, the
parties expressly agree that all the terms and provisions hereof shall be
construed in accordance with and governed by the laws of the State of New York
without regard to that State's conflicts of law principles. In the event that a
judicial proceeding is necessary, the sole forum for resolving disputes arising
out of or relating to this agreement is any federal or state court in the State
of New York, and all related appellate courts (collectively, the "Courts"). The
parties irrevocably and unconditionally consent to the jurisdiction of such
courts.

            (b) Each of the parties irrevocably and unconditionally consents to
venue in the Courts, and irrevocably and unconditionally waives any objection to
the laying of venue of any judicial proceeding in the Courts, and agrees not to
plead or claim in any such Court that any such judicial proceeding brought in
any such court has been brought in an inconvenient forum.

            9.5 Severability. The holding of any provision of this Agreement to
be invalid or unenforceable by a court of competent jurisdiction shall not
affect any other provision of this Agreement, which shall remain in full force
and effect. If any provision of this Agreement shall be declared by a court of
competent jurisdiction to be invalid, illegal or incapable of being enforced in
whole or in part, such provision shall be interpreted so as to remain
enforceable to the maximum extent permissible consistent with applicable law and
the remaining conditions and provisions or portions thereof shall nevertheless
remain in full force and effect and enforceable to the extent they are valid,
legal and enforceable, and no provisions shall be deemed dependent upon any
other covenant or provision unless so expressed herein.

            9.6 No Waiver. A waiver by either party of a breach of any provision
of this Agreement shall not operate, or be construed, as a waiver of any
subsequent breach by that same party.

                                                                              13


            9.7 Further Assurances. The parties agree to execute and deliver all
such further documents, agreements and instruments and take such other and
further action as may be necessary or appropriate to carry out the purposes and
intent of this Agreement. Any documentary, stamp tax or similar issuance or
transfer taxes due as a result of the conveyance, transfer or sale of the
Preferred Shares between any of the Purchasers (or any of their permitted
transferees), on the one hand, and the Company, on the other hand, pursuant to
this Agreement shall be borne by such Purchasers (or their respective permitted
transferees).

            9.8 Counterparts. This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original, but all of which shall
together constitute the same instrument.

            9.9 No Third Party Beneficiaries. Nothing in this Agreement shall
create or be deemed to create in any person or entity not a party to this
Agreement any legal or equitable right, remedy or claim under this Agreement,
and this Agreement shall be for the sole and exclusive benefit of the parties
hereto. The parties hereto expressly recognize that this Agreement is not
intended to create a partnership, joint venture or other similar arrangement
between or among any of such parties or their respective affiliates.

            9.10 Publicity Restrictions. No press release or other public
disclosure relating to the transactions contemplated by this Agreement shall be
issued or made by or on behalf of any Purchaser without prior consultation with
the Company, except as required by applicable law, court process or stock
exchange rules, in which case the Purchaser required to make such disclosure
shall allow the Company reasonable time (to the extent practicable) to comment
thereon in advance of such issuance.




            IN WITNESS WHEREOF, the undersigned have duly executed this
Agreement as of the date first above written.

declaration and setting apart for payment of any amount shall be made in respect
of Junior Stock, an amount equal to $1,000 per share (subject to appropriate
adjustment to reflect any stock split, combination, reclassification or
reorganization of the Series A Preferred Stock) plus an amount equal to all
declared and unpaid dividends thereon. If upon any Liquidation Event, whether
voluntary or involuntary, the assets to be distributed to the holders of the
Series A Preferred Stock shall be insufficient to permit the payment to such
shareholders of the full preferential amounts aforesaid, then all of the assets
of the Corporation to be distributed shall be so distributed ratably to the
holders of the Series A Preferred Stock on the basis of the number of shares of
Series A Preferred Stock held. All shares of Series A Preferred Stock shall rank
as to payment, upon the occurrence of a Liquidation Event, senior to the Common
Stock as provided herein and, unless the terms of such series shall provide
otherwise, senior to all other series of the Corporation's preferred stock.

            (a) Restriction on Redemption and Purchase. Except as expressly
provided in this Section 6, the Corporation shall not have the right to
purchase, call, redeem or otherwise acquire for value any or all of the Series A
Preferred Stock.

            (b) Optional Redemption. At any time after the first anniversary of
the Issuance Date, the Corporation may, at its option, redeem the Series A
Preferred Stock in whole, but not in part, at the Redemption Price hereinafter
specified; provided, however, that the Corporation shall not redeem Series A
Preferred Stock or give notice of any redemption unless the Corporation has
sufficient and lawful funds to redeem all of the then outstanding Series A
Preferred Stock. The date on which the Series A Preferred Stock is to be
redeemed pursuant to this Section 6(b) is herein called the "Redemption Date."

            (c) Redemption Price. The Redemption Price of the Series A Preferred
Stock (the "Redemption Price") shall be an amount per share equal to $1,100
(subject to appropriate adjustment to reflect any stock split, combination,
reclassification or reorganization of the Series A Preferred Stock) plus all
declared and unpaid dividends thereon, to and including the Redemption Date.

            (d) Redemption Notice. The Corporation shall, not less than thirty
(30) days nor more than sixty (60) days prior to the Redemption Date, give
written notice ("Redemption Notice") to each holder of record of Series A
Preferred Stock to be redeemed. The Redemption Notice shall state:

                  (1)   that all of the outstanding shares of Series A Preferred
                        Stock are to be redeemed and the total number of shares
                        being redeemed;

                  (2)   the number of shares of Series A Preferred Stock held by
                        the holder which the Corporation intends to redeem;

                  (3)   the Redemption Date and Redemption Price;

                  (4)   that the holder's right to convert the Series A
                        Preferred Stock into shares of the Common Stock as
                        provided in Section 8 hereof will terminate on the
                        Redemption Date; and

                  (5)   the time, place and manner in which the holder is to
                        surrender to the Corporation the certificate or
                        certificates representing the shares of Series A
                        Preferred Stock to be redeemed.

            (e) Payment of Redemption Price and Surrender of Stock. On the
Redemption Date, the Redemption Price of the Series A Preferred Stock scheduled
to be redeemed or called for redemption shall be payable to the holders of the
Series A Preferred Stock. On or before the Redemption Date, each holder of
Series A Preferred Stock to be redeemed, unless the holder has exercised his
right to convert the shares as provided in Section 8 hereof, shall surrender the
certificate or certificates representing such shares to the Corporation, in the
manner and at the

                                                                               5


place designated in the Redemption Notice, and thereupon the Redemption Price
for such shares shall be payable to the order of the person or entity whose name
appears on such certificate or certificates as the owner thereof, and each
surrendered certificate shall be cancelled and retired.

            (f) Termination of Rights. If the Redemption Notice is duly given,
and, if at least ten (10) days prior to the Redemption Date, the Redemption
Price is either paid or made available for payment through the arrangement
specified in subsection (g) below, then notwithstanding that the certificates
evidencing any of the shares of Series A Preferred Stock so called or scheduled
for redemption have not been surrendered, all rights with respect to such shares
shall forthwith after the Redemption Date cease and terminate, except only (i)
the right of the holders to receive the Redemption Price without interest upon
surrender of their certificates therefor or (ii) the right to receive shares of
Common Stock upon exercise of the conversion rights provided in Section 8 hereof
on or before the Redemption Date.

            (g) Deposit of Funds. At least ten (10) days prior to the Redemption
Date, the Corporation shall deposit with any bank or trust company in New York,
New York, a sum equal to the aggregate Redemption Price of all shares of the
Series A Preferred Stock scheduled to be redeemed or called for redemption and
not yet redeemed, with irrevocable instructions and authority to the bank or
trust company to pay the Redemption Price to the respective holders upon the
surrender of their share certificates. The deposit shall constitute full payment
for the shares of Series A Preferred Stock to the holders thereof, and from and
after the later of the date of such deposit and the Redemption Date, the shares
of Series A Preferred Stock shall be deemed to be redeemed and no longer
outstanding, and the holders thereof shall cease to be shareholders with respect
to such shares of Series A Preferred Stock and shall have no rights with respect
thereto, except the right to receive from the back or trust company payment of
the Redemption Price of the shares of Series A Preferred Stock, without
interest, upon surrender of their certificates therefor and the right, prior to
the Redemption Date, to convert such shares of Series A Preferred Stock into
shares of Common Stock as provided in Section 8 hereof. Any monies so deposited
and unclaimed at the end of one year from the Redemption Date shall be released
or repaid to the Corporation, after which time the holder of shares of Series A
Preferred Stock called for redemption shall be entitled to receive payment of
the Redemption Price only from the Corporation.

            Section 7. Voting Rights.

            (a) Series A Preferred Stock. Except as set forth in paragraph (b)
of this Section, the holders of Series A Preferred Stock shall have no voting
rights on any matters.

            (b) Amendment of Certificate of Incorporation. Any amendment to the
Certificate of Incorporation of the Corporation that adversely affects the
conversion terms or other economic rights or preferences of the Series A
Preferred Stock shall require the approval of the holders of a Supermajority of
the Series A Preferred Stock. The adoption of a Certificate of Designations for
a senior class of Preferred Stock by itself shall be deemed to not constitute an
amendment to the Certificate of Incorporation of the Corporation for the
purposes of this Section.

                                                                               6


            Section 8. Conversion. The holders of Series A Preferred Stock shall
have the following conversion rights:

            (a) Right to Convert. Each share of Series A Preferred Stock shall
be convertible, at any time at the option of the holder thereof, into validly
issued, fully paid and nonassessable shares of Common Stock.

            (b) Series A Conversion Ratio. Each share of Series A Preferred
Stock shall be convertible into shares of Common Stock at a ratio (the "Series A
Conversion Ratio") equal to 300 shares of Common Stock for each share of Series
A Preferred Stock, subject to adjustment as hereinafter provided; provided,
however, that if the Conversion Adjustment Condition has not been satisfied on
or prior to February 28, 2000, the Series A Conversion Ratio shall be equal to
450 shares of Common Stock for each outstanding share of Series A Preferred
Stock from and after such February 28, 2000 date, subject to adjustment as
hereinafter provided.

            (c) Dividends Upon Conversion. Upon conversion, all accrued and
unpaid dividends (whether or not declared), if any, on the Series A Preferred
Stock shall be canceled.

            (d) Automatic Conversion.

                  (1) The Series A Preferred Stock will be automatically
converted into shares of Common Stock (i) in the event of (A) any consolidation
or merger of the Corporation with or into any other unrelated corporation or
other entity in which the Corporation is not the surviving entity, or any other
corporate reorganization or transaction or series of related transactions by the
Corporation in which in excess of 75% of the Corporation's voting power is
transferred to an unrelated person or entity, or (B) a sale or other disposition
of all or substantially all of the assets of the Corporation (any such event in
(A) or (B), a "Merger Transaction") or (ii) upon receipt by the Corporation of a
written notice from the holders of a Supermajority of the Series A Preferred
Stock electing to convert their shares of Series A Preferred Stock.

                  (2) Upon the occurrence of any of the events specified in
paragraph (d)(1) above, the outstanding shares of Series A Preferred Stock shall
be converted automatically without any further action by the holders of such
shares and whether or not the certificates representing such shares are
surrendered to the Corporation or its transfer agent; provided, however, that
the Corporation shall not be obligated to issue certificates evidencing the
shares of Common Stock issuable upon such conversion unless the certificates
evidencing such shares of Series A Preferred Stock are either delivered to the
Corporation or its transfer agent as provided below, or the holder thereof
notifies the Corporation or its transfer agent that such certificates have been
lost, stolen, mutilated or destroyed and executes an agreement satisfactory to
the Corporation to indemnify the Corporation from any loss incurred by it in
connection with such certificates. Upon the occurrence of such automatic
conversion of the Series A Preferred Stock, the holders of Series A Preferred
Stock shall surrender the certificates representing such shares at the office of
the Corporation or any transfer agent for the Series A Preferred Stock.
Thereupon, there shall be issued and delivered to such holder promptly at such
office and in its name as

                                                                               7


shown on such surrendered certificate or certificates, a certificate or
certificates for the number of shares of Common Stock into which the share of
Series A Preferred Stock surrendered were convertible on the date on which such
automatic conversion occurred.

            (e) Mechanics of Conversion. Each holder of Series A Preferred Stock
that desires to convert its shares of Series A Preferred Stock into shares of
Common Stock shall surrender the certificate or certificates therefor, duly
endorsed, at the office of the Corporation or of any transfer agent for the
Series A Preferred Stock or Common Stock, and shall give written notice to the
Corporation at such office that such holder elects to convert the same and shall
state therein the number of shares of Series A Preferred Stock being converted.
Thereupon the Corporation shall promptly issue and deliver to such holder a
certificate or certificates for the number of shares of Common Stock to which
such holder is entitled. Such conversion shall be deemed to have been made
immediately prior to the close of business on the date of such surrender of the
certificate or certificates representing the shares of Series A Preferred Stock
to be converted, and the person or entity entitled to receive the shares of
Common Stock issuable upon such conversion shall be treated for all purposes as
the record holder of such shares of Common Stock on such date. In the event that
a notice to convert is given following a Redemption Notice and such redemption
is not consummated, the conversion shall, at the option of the holder of the
Series A Preferred Stock who tendered for conversion, be voidable and such
holder shall have the right to maintain ownership of the shares of Series A
Preferred Stock tendered for conversion.

            (f) Adjustment for Stock Splits and Combinations. If the Corporation
at any time or from time to time after the Issuance Date effects a subdivision
of the outstanding Common Stock, the Series A Conversion Ratio then in effect
immediately before that subdivision shall be proportionately increased (and the
Series A Conversion Ratio that would apply after February 28, 2000, if the
Conversion Adjustment Condition is not satisfied, shall be proportionately
increased), and conversely, if the Corporation at any time or from time to time
after the Issuance Date combines the outstanding shares of Common Stock into a
smaller number of shares, the Series A Conversion Ratio then in effect
immediately before the combination shall be proportionately decreased (and the
Series A Conversion Ratio that would apply after February 28, 2000, if the
Conversion Adjustment Condition is not satisfied, shall be proportionately
decreased). Any adjustment under this subsection (f) shall become effective at
the close of business on the date the subdivision or combination becomes
effective.

            (g) Adjustment for Certain Dividends and Distributions. If the
Corporation at any time or from time to time after the Issuance Date makes, or
fixes a record date for the determination of holders of Common Stock entitled to
receive, a dividend or other distribution payable in additional shares of Common
Stock, then and in each such event the Series A Conversion Ratio then in effect
shall be increased (and the Series A Conversion Ratio that would apply after
February 28, 2000, if the Conversion Adjustment Condition is not satisfied,
shall be proportionately increased) as of the time of such issuance or, in the
event such record date is fixed, as of the close of business on such record
date, by multiplying the Series A Conversion Ratio then in effect by a fraction
(1) the numerator of which shall be the total number of shares of Common Stock
issued and outstanding immediately prior to the time of such issuance or the

                                                                               8


close of business on such record date plus the number of shares of Common Stock
issuable in payment of such dividend or distribution, and (2) the denominator of
which shall be the total number of shares of Common Stock issued and outstanding
immediately prior to the time of such issuance or the close of business on such
record date; provided, however, that, if such record date is fixed and such
dividend is not fully paid or if such distribution is not fully made on the date
fixed therefor, the Series A Conversion Ratio shall be recomputed accordingly as
of the close of business on such record date and thereafter the Series A
Conversion Ratio shall be adjusted pursuant to this subsection (g) as of the
time of actual payment of such dividends or distributions.

            (h) Adjustment for Reclassification, Exchange and Substitution. In
the event that at any time or from time to time after the Issuance Date, the
Common Stock issuable upon the conversion of the Series A Preferred Stock is
changed into the same or a different number of shares of any class or classes of
stock, whether by recapitalization, reclassification or otherwise (other than a
subdivision or combination of shares of stock dividend or a reorganization,
merger, consolidation or sale or assets, provided for elsewhere in this Section
8), then and in any such event each holder of Series A Preferred Stock shall
have the right thereafter to convert such Series A Preferred Stock into the kind
and amount of stock and other securities and property receivable upon such
recapitalization, reclassification or other change, by holders of the maximum
number of shares of Common Stock into which such shares of Series A Preferred
Stock could have been converted immediately prior to such recapitalization,
reclassification or change, all subject to further adjustment as provided
herein.

            (i) Certificate of Adjustment. In each case of an adjustment or
readjustment of the Series A Conversion Ratio, the Corporation, at its expense,
shall cause its Chief Financial Officer or Chief Accounting Officer to compute
such adjustment or readjustment in accordance with the provisions hereof and
prepare a certificate showing such adjustment or readjustment, and shall mail
such certificate, by certified mail, return receipt requested, postage prepaid,
to cash registered holder of Series A Preferred Stock at the holder's address as
shown in the Corporation's books. The certificate shall set forth such
adjustment or readjustment, showing in detail the facts upon which such
adjustment or readjustment is based, including a statement of (1) the Series A
Conversion Ratio at the time in effect and (2) the type and amount, if any, of
other property which at the time would be received upon conversion of the Series
A Preferred Stock.

            (j) Fractional Shares. No fractional shares of Common Stock shall be
issuable upon conversion of the Series A Preferred Stock. In lieu of any
fractional share to which the holder would otherwise be entitled, the
Corporation shall pay cash equal to the product of such fraction multiplied by
the fair market value of one share of Common Stock on the date of conversion, as
determined in good faith by the Board.

            (k) Reservation of Common Stock Issuable Upon Conversion. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Series A Preferred Stock, such number of its
shares of Common Stock as shall from time to time be sufficient to effect the
conversion of all outstanding shares of the Series A Preferred Stock.

                                                                               9


            (l) Notices. Any notice required or permitted by this Section 8 or
any other provision hereof to be given shall be deemed sufficient and effective
when received if in writing and sent by hand delivery, overnight courier or
certified or registered mail, return receipt requested, postage prepaid, and
addressed (x) to a holder of record of Series A Preferred Stock at the address
of such holder appearing on the books of the Corporation, or (y) to the
Corporation at 115 Stevens Avenue, Valhalla, NY, 10595 or (z) to the Corporation
or any such holder, at any other address for the giving of notice specified in a
written notice given to the other.

            (m) Payment of Taxes and Other Charges. The Corporation will pay all
taxes (other than taxes based upon income) and other governmental or third party
charges that may be imposed with respect to the issue or delivery of shares of
Common Stock upon conversion of shares of Series A Preferred Stock, including,
without limitation, any tax or other charge imposed in connection with any
transfer involved in the issue and delivery of shares of Common Stock in a name
other than that in which the shares of Series A Preferred Stock so converted
were registered.

            Section 9. No Amendment or Impairment. The Corporation shall not
amend its Certificate of Incorporation or participate in any reorganization,
transfer of assets, consolidation, merger, dissolution, issue or sale of
securities or any other voluntary action, for the purpose of avoiding or seeking
to avoid the observance or performance of any of the terms to be observed or
performed hereunder by the Corporation.

            Section 10. No Reissuance of Series A Preferred Stock. No share or
shares of Series A Preferred Stock acquired by the Corporation by reason of
redemption, purchase, conversion or otherwise shall be reissued.

            Section 11. Outstanding Shares. For the purpose of this Certificate
of Designations, all shares of Series A Preferred Stock issued shall be deemed
outstanding except (i) from the date, or the deemed date, of surrender of
certificates evidencing shares of Series A Preferred Stock, all shares of Series
A Preferred Stock converted into Common Stock, (ii) from the date of
registration of transfer, all shares of Series A Preferred Stock held of record
by the Corporation or any subsidiary of the Corporation and (iii) any and all
shares of Series A Preferred Stock held (in escrow or otherwise) prior to
delivery of such stock by the Corporation to the initial beneficial owners
thereof.

            Section 12. Status of Acquired Shares. Shares of Series A Preferred
Stock received upon redemption, purchase, conversion or otherwise acquired by
the Corporation will be restored to the status of authorized but unissued shares
of Preferred Stock, without designation as to class, and may thereafter be
issued, but not as shares of Series A Preferred Stock.

            Section 13. Preemptive Rights. The Series A Preferred Stock is not
entitled to any preemptive or subscription rights in respect of any securities
of the Corporation.

            Section 14. Severability of Provisions. Whenever possible, each
provision hereof shall be interpreted in a manner as to be effective and valid
under applicable law, but if

                                                                              10


any provision hereof is held to be prohibited by or invalid under applicable law
, such provision shall be ineffective only to the extent of such prohibition or
invalidity, without invalidating or otherwise adversely affecting the remaining
provisions hereof. If a court of competent jurisdiction should determine that a
provision hereof would be valid or enforceable if a period of time were extended
or shortened or a particular percentage were increased or decreased, then such
court may make such change as shall be necessary to render the provision in
question effective and valid under applicable law.
