     THIS SUBSCRIPTION AGREEMENT ("Agreement") is made as of March 27, 2001, by
and between JOHN J. CADIGAN ("PURCHASER"), and STRATEGIC SOLUTIONS GROUP, INC.,
a Delaware corporation ("SELLER").

                                  WITNESSETH

     WHEREAS, SELLER desires to obtain additional working capital through the
sale and issuance of "Units". As used in this Agreement, a "Unit" means 50,000
shares of the common voting stock, par value $0.0001 of SELLER ("Common Stock"),
and a Convertible Subordinated Debenture made payable to the PURCHASER for the
principal amount of Twenty-Five Thousand Dollars ($25,000), bearing interest at
a rate of ten percent (10%) per annum, and with the outstanding principal
balance convertible into Common Stock at a conversion price of $.10 per share
("Debenture").

     WHEREAS, SELLER has offered to sell, and PURCHASER desires to acquire Units
in accordance with the terms and conditions of this Agreement.

     NOW, THEREFORE, in consideration of the mutual undertakings herein and
other good and valuable consideration, the sufficiency of which is hereby
acknowledged, the parties hereto do hereby agree as follows:

     Section 1.   Purchase and Sale of Units. SELLER hereby agrees to sell to
                  --------------------------
PURCHASER and PURCHASER hereby agrees to purchase, two (2) Units, in exchange
for the sum of Fifty Thousand Dollars ($50,000) ("Purchase Price"), and upon the
terms and conditions described herein. Upon receipt of the Purchase Price and
the below-defined Accredited Investor Certificate, SELLER will (i) execute and
deliver a Debenture for the principal amount corresponding to the number of
Units purchased as defined above, and (ii) instruct its transfer agent to issue
and deliver a certificate representing the corresponding number of shares of
Common Stock to PURCHASER or its nominee.

     Section 2.   Purchaser Representations and Warranties. PURCHASER hereby
                  ----------------------------------------
acknowledges, represents and warrants to, and agrees with, SELLER as follows:

            (a)   "Accredited Investor"; Resale Restrictions.
                  ------------------------------------------

                  (i)    The PURCHASER is an "accredited investor" as that term
     is defined in Regulation D promulgated under the Securities Act of 1933.
     The

<PAGE>

     PURCHASER will accurately complete and return the Accredited Investor
     Certificate attached hereto as Appendix A.
                                    ----------

                  (ii)   The PURCHASER is purchasing the Units for the
     PURCHASER's own account, for investment, and not with a view to, or for
     offer or sale in connection with, any distribution thereof in violation of
     the Securities Act.

                  (iii)  The Debenture and the certificates representing the
     Common Stock will bear a legend substantially as follows:

          [THIS CONVERTIBLE SUBORDINATED DEBENTURE AND THE SHARES OF COMMON
          STOCK ISSUABLE UPON CONVERSION] [THE SHARES OF COMMON STOCK
          REPRESENTED HEREBY] HAVE NOT BEEN REGISTERED UNDER THE UNITED STATES
          SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT
          BE OFFERED OR SOLD EXCEPT PURSUANT TO REGISTRATION UNDER THE
          SECURITIES ACT OR PURSUANT TO AN AVAILABLE EXEMPTION FROM
          REGISTRATION. THE ISSUER WILL REFUSE TO REGISTER ANY TRANSFER OF SUCH
          SECURITIES NOT MADE IN ACCORDANCE WITH THE SECURITIES ACT AND MAY
          REQUIRE, AS A CONDITION TO ANY REGISTRATION OF TRANSFER, AN OPINION OF
          COUNSEL, A CERTIFICATE OR SUCH OTHER EVIDENCE AS MAY BE SATISFACTORY
          TO THE ISSUER TO THE EFFECT THAT THE TRANSFER HAS BEEN MADE IN
          ACCORDANCE WITH THE SECURITIES ACT.

                  (iv)   The PURCHASER agrees that it will only offer, sell or
     transfer the Common Stock prior to the date which is two years (or such
     shorter period of time as permitted by Rule 144 under the Securities Act or
     any successor provisions thereunder) after the date on which the Units are
     issued to the PURCHASER or such later date, if any, as may be required by
     applicable law, to (i) SELLER, (ii) pursuant to a registration statement
     that has been declared effective under the Securities Act; or (iii)
     pursuant to an available exemption from the registration requirements of
     the Securities Act.

            (b)   Investor Suitability; Independent Investigation; Access to
                  ----------------------------------------------------------
Information; Risk Factors.
-------------------------

                  (i)    PURCHASER has the financial ability to bear the
     economic risk of his investment in the SELLER (including its possible loss)
     and has no need for liquidity with respect to his investment in the Units.

                  (ii)   PURCHASER has such knowledge and experience in
     financial and business matters so as to be capable of evaluating the merits
     and risks of an investment in the Units and has obtained, in its judgment,
     sufficient information from SELLER to evaluate the merits and risks of an
     investment in the Units.

                  (iii)  The Units are not being subscribed for by PURCHASER as
     a result of any material information about SELLER's affairs that has not
     been publicly disclosed.

                                       2
<PAGE>

                  (iv)   PURCHASER acknowledges that SELLER regularly files
     publicly available reports under the Securities Exchange Act of 1934 (the
     "Exchange Act") and PURCHASER is familiar with the previous reports filed
     by SELLER with the Securities and Exchange Commission (the "SEC").

                  (v)    PURCHASER acknowledges that an investment in SELLER
     involves a high degree of risk, and has taken full cognizance of and
     understands all of the risk factors related to an investment in SELLER.

                  (vi)   PURCHASER has determined that an investment in the
     Units is a suitable investment for it.

                  (vii)  In making its decision to purchase the Units herein
     subscribed for, PURCHASER has relied solely upon independent investigations
     made by it. PURCHASER is not relying on SELLER with respect to tax and
     other economic considerations involved in his investment.

                  (viii) PURCHASER understands that sales or transfers of the
     Units, or any part thereof, may be further restricted by provisions of the
     applicable state securities laws. However, SELLER agrees to file a
     registration statement with the Securities and Exchange Commission for a
     public offering of its Units or the resale of certain of its Common Stock
     within one year of the closing of PURCHASER's acquisition of the Units
     under this Agreement.

     Section 3.   Seller Representations and Warranties. SELLER hereby
                  -------------------------------------
acknowledges, represents and warrants to, and agrees with, PURCHASER as follows:

            (a)   Seller Reports and Financial Statements.
                  ---------------------------------------

                  (i)    SELLER is registered under the Exchange Act and has
     filed all forms and reports required to be filed with the SEC
     (collectively, the "SELLER SEC Reports"). The SELLER SEC Reports were
     prepared in all material respects in accordance with the requirements of
     applicable law (including the Exchange Act and the rules and regulations of
     the SEC thereunder applicable to such SELLER SEC Reports). As of their
     respective dates, the SELLER SEC Reports did not contain any untrue
     statement of a material fact or omit to state a material fact required to
     be stated therein or necessary to make the statements made therein, in the
     light of the circumstances under which they were made, not misleading.

                  (ii)   Each of the financial statements (including, in each
     case, any related notes thereto) contained in the SELLER SEC Reports, if
     any, filed prior to, on or after the date of this Agreement (i) have been
     or will be prepared in accordance with, and complied or will comply as to
     form with, the published rules and regulations of the SEC and GAAP applied
     on a consistent basis throughout the periods involved (except as otherwise
     noted therein) and (ii) fairly present or will fairly present the financial
     position of SELLER as of the respective dates thereof and the results of
     its operations and cash flows for the periods indicated, except that any
     unaudited interim financial statements were or will be subject to normal
     and recurring year-end adjustments.

                  ----------------------------

and validly authorized and, when so issued in accordance with the terms of this
Agreement, will be duly and validly issued, fully paid and nonassessable.

     Section 4.     Indemnity. PURCHASER and SELLER each hereby agrees to
                    ---------
indemnify and hold harmless the other and its respective officers, directors and
agents and each other person, if any, who controls or is controlled by any
thereof, within the meaning of Section 15 of the Securities Act, against any and
all loss, liability, claim, damage and expense whatsoever (including, but not
limited to, any and all expenses whatsoever reasonably incurred in
investigating, preparing or defending against any litigation commenced or
threatened or any claim whatsoever) arising out of or based upon any false
representation or warranty or breach or failure by the indemnifying party herein
or in any other document furnished in connection with this transaction by the
indemnifying party to the other party or any of it officers, directors, agents

                          REGISTRATION RIGHTS AGREEMENT

        THIS REGISTRATION RIGHTS AGREEMENT (this "Agreement") is entered into as
of March 27, 2001 ("Effective Date") between STRATEGIC SOLUTIONS GROUP, INC., a
Delaware corporation (the "Company"), and JOHN J. CADIGAN (the "Investor").

                                   RECITALS
                                   --------

        A. The Investor has executed a Subscription Agreement of even date
hereof ("Subscription Agreement") for the purchase of "Units", with each Unit
consisting of 50,000 shares of the Company's common stock, par value $.0001 (the
"Common Stock") and a Convertible Subordinated Debenture for the principal
amount of Twenty Five Thousand Dollars ($25,000) (the "Debenture").

        B. The Company has agreed to enter this Agreement with each investor
(collectively, "Investors") that subscribes to purchase Units pursuant to a
Subscription Agreement in substantially the form executed by the Investor.

        NOW, THEREFORE, in consideration of these premises, the terms and
conditions set forth herein, and other good and valuable consideration, the
receipt and sufficiency of which are acknowledged, the Company and the Investor
agree as follows:

        1.     Registration.
               ------------

               (a)  Agreement to Register. The Company covenants and agrees to
                    ---------------------
cause the Investor's Common Stock and the Registrable Securities (as defined
below) to be registered with the Securities and Exchange Commission
("Commission") under the Securities Act of 1933 (the "Securities Act"), within
365 days from the Effective Date ("Registration Deadline"). The securities
entitled to the benefits of this Agreement ("Registrable Securities") are (i)
the shares of Common Stock subscribed and purchased by the Investor pursuant to
the Subscription Agreement, and (ii) any securities issued or issuable upon the
Investor's conversion of the Debentures (and after giving effect to any stock
split, recapitalization, reclassification, merger, consolidation or exchange
offer). For purposes of this Agreement, a Registrable Security ceases to be a
Registrable Security when it has been sold or distributed to any person pursuant
to Rule 144 of the Securities Act.

               (b)  Procedure and Duration. The Company will prepare and file
                    ----------------------
with the Commission the necessary registration statement, amendments,
supplements and other filings (collectively, "Registration Statement") for an
offering to be made covering the resale by the Investors thereof of all the
Registrable Securities. The registration will be on Form S-3 or another
appropriate form permitting registration of such Registrable Securities for
resale by the Investors. The Company will cause the Registration Statement to
remain continuously effective under the Securities Act for a period of thirty
(30) days (the "Effectiveness Period").

        2.     Failure to Register. In the event that the Registration Statement
               -------------------
is not declared
<PAGE>

effective by the Commission on or before the Registration Deadline, then the
Company shall pay to the Investor an amount equal to three percent (3%) of the
Investor's original purchase price of the Registrable Securities per month, for
each month that the Registration Statement has not been declared effective.
Payment of amounts due and owing under this Section 2 shall be payable by the
Company within thirty (30) days of its receipt of a written demand from the
Investor.

        3.     Company Covenants.
               -----------------

        (a)    If the Registration Statement ceases to be effective for any
reason at any time during the Effectiveness Period (other than because of the
sale of all of the securities registered thereunder), the Company will obtain
the prompt withdrawal of any order suspending the effectiveness thereof, and
will within thirty (30) days of such cessation of effectiveness amend the
Registration Statement in a manner reasonably expected to obtain the withdrawal
of the order suspending the effectiveness thereof, or file an additional
Registration Statement covering all of the Registrable Securities (that have not
otherwise been sold or transferred).

        (b)    The Company will supplement and amend the Registration Statement
if required by the rules, regulations or instructions applicable to the
registration form used by the Company, if required by the Securities Act, or if
reasonably requested by the Investors holding a majority in aggregate principal
amount of the Registrable Securities ("Majority Registrable Investors").

        (c)    The Company will notify the Investors (providing, if requested by
any such persons, confirmation in writing) as soon as practicable after becoming
aware of: (A) the filing of the Registration Statement or any post-effective
amendment thereto; (B) any request by the Commission for amendments or
supplements to such Registration Statement or for additional information; (C)
the receipt by the Company of any notification with respect to the suspension of
the qualification or registration (or exemption therefrom) of any Registrable
Securities for sale in any jurisdiction in the United States or the initiation
or threatening of any proceeding for such purposes; or (E) the happening of any
event that makes any statement made in such Registration Statement or any
supplement, amendment or document incorporated therein by reference untrue in
any material respect or that requires the making of any changes in such
Registration Statement or in any such supplement, amendment or other such
document so that it will not contain any 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.

        (d)    As soon as practicable after filing such documents with the
Commission, the Company will furnish to the Investor, without charge, at least
one manually signed or conformed copy of the Registration Statement and any
post-effective amendment thereto, including financial statements and schedules;
and as soon as practicable after the request of any Investor furnish to such
Investor at least one copy of any document incorporated by reference in such
Registration Statement or in any supplement or amendment, together with all
exhibits thereto (including those previously furnished or incorporated by
reference).

                                       2
<PAGE>

        (e)    The Company will cooperate with the Investors and their
respective counsel in connection with the registration or qualification (or
exemption therefrom) of such Registrable Securities for offer and sale under the
securities or blue sky laws of such jurisdictions in the United States as the
Investor will reasonably request in writing; and do any and all other acts and
things reasonably necessary or advisable to facilitate the disposition in such
jurisdictions of the Registrable Securities covered by such Registration
Statement; provided that the Company will not be required to qualify generally
to do business in any jurisdiction where it would not be required to qualify but
for this Agreement.

        (f)    The Company shall make available for inspection during reasonable
business hours by the Investor, and any attorney, accountant or other
representative retained by such selling Investor (provided that no more than two
law firms and one accounting firm will be retained by the Investor) all
pertinent financial and other records, pertinent corporate documents and
properties of the Company, and cause the Company's officers, directors and
employees to supply all information reasonably requested by any such
underwriter, attorney, accountant or other representative in connection with
such registration; provided, however, that if any information is determined in
good faith by the Company to be of a confidential nature at the time of delivery
of such information, then prior to delivery of such information, the Company and
the Investor will enter into a confidentiality agreement reasonably acceptable
to the Company and the Investor.

        4.     Investor Covenants.  The Investor hereby covenants and agrees to
               ------------------
use its best efforts to cooperate with the Company in all reasonable respects in
connection with the preparation and filing of the Registration Statement in
which such Registrable Securities are included or requested to be included.

        5.     Registration Expenses. All expenses incident to the Company's
               ---------------------
performance of or compliance with this Agreement, including without limitation
all registration and filing fees, fees and expenses of compliance with
securities or blue sky laws (including reasonable fees and disbursements of
counsel in connection with blue sky qualifications or registrations (or the
obtaining of exemptions therefrom) of the Registrable Securities), printing
expenses, messenger and delivery expenses, internal expenses, fees and
disbursements of its counsel and its independent certified public accountants,
securities acts liability insurance (if the Company elects to obtain such
insurance), reasonable fees and expenses of any special experts retained by the
Company in connection with any registration hereunder and reasonable fees and
expenses of other persons retained by the Company (all such expenses being
herein referred to as "Registration Expenses"), will be borne by the Company;
provided that Registration Expenses will not include any commissions or fees
--------
attributable to the sale of the Registrable Securities or fees and expenses of
counsel for any Investor or out-of-pocket expenses of any Investor which will be
paid by the Investor as incurred.

        6.     Indemnification; Contribution.
               -----------------------------

                                       3
<PAGE>

               (a)  Indemnification by the Company. The Company will indemnify,
                    ------------------------------
to the full extent permitted by law, each Investor holding Registrable
Securities and any investment adviser thereof or agent therefor, against all
losses, claims, damages, liabilities and expenses (including reasonable costs of
investigation and legal expenses) arising out of or based upon any untrue or
alleged untrue statement of a material fact contained in any Registration
Statement covering any Registrable Securities, or any amendment or supplement
thereto, or any omission or alleged omission to state in any thereof a material
fact required to be stated therein or necessary to make the statements therein
not misleading, except in each case insofar, but only insofar, as the liability
arises out of or is based upon an untrue statement or alleged untrue statement
of a material fact or an omission or alleged omission to state a material fact
in such Registration Statement, amendment or supplement, as the case may be,
made or omitted, as the case may be, in reliance upon and in conformity with
written information furnished to the Company by such Investor expressly for use
therein. This indemnity is in addition to any liability that the Company may
otherwise have.

               (b)  Indemnification by Investor of Registrable Securities. Each
                    -----------------------------------------------------
Investor whose Registrable Securities are covered by an applicable Registration
Statement must furnish to the Company in writing such information and affidavits
with respect to such Investor as the Company reasonably requests for use in
connection with such Registration Statement, or any amendment or supplement
thereto, and will indemnify, to the full extent permitted by law, the Company,
the Company's directors, officers, employees and agents, each person or entity
who controls the Company (within the meaning of the Securities Act) and any
investment adviser thereof or agent therefor, against all losses, claims,
damages, liabilities and expenses (including reasonable costs of investigation
and legal expenses) arising out of or based upon any untrue or alleged untrue
statement of a material fact contained in any Registration Statement covering
any Registrable Securities, or any amendment or supplement thereto, or any
omission or alleged omission to state in any thereof a material fact required to
be stated therein or necessary to make the statements therein not misleading, in
each case to the extent, but only to the extent, that the same arises out of or
is based upon an untrue statement or alleged untrue statement of a material fact
or an omission or alleged omission to state a material fact in such Registration
Statement, amendment or supplement, as the case may be, made or omitted, as the
case may be, in reliance upon and in conformity with written information
furnished to the Company by such Investor expressly for use therein; provided,
however, that in no event will the liability of any Investor for indemnification
under this Section 6(b) exceed the proceeds received by such Investor from the
sale of Registrable Securities under the applicable Registration Statement. This
indemnity is in addition to any liability that an Investor may otherwise have.

               (c)  Conduct of Indemnification Proceedings. Any party entitled
                    --------------------------------------
to indemnification under this Section 6 agrees to give prompt written notice to
the indemnifying party after the receipt by such party of any written notice of
the commencement of any action, suit, proceeding or investigation or threat
thereof made in writing for which such party will claim indemnification or
contribution pursuant to this Agreement and, unless in the reasonable judgment
of such indemnified party a conflict of interest may exist between such
indemnified

                                       4

party and the indemnifying party with respect to such claim, permit the
indemnifying party to assume the defense of such claim with counsel reasonably
satisfactory to such indemnified party. If the indemnifying party is not
entitled to, or elects not to, assume the defense of a claim, it will not be
obligated to pay the reasonable fees and expenses of more than one counsel with
respect to such claim, unless in the reasonable judgment of counsel to such
indemnified party, expressed in a writing delivered to the indemnifying party, a
conflict of interest may exist between such indemnified party and any other
indemnified party with respect to such claim, in which event the indemnifying
party will be obligated to pay the reasonable fees and expenses of such
additional counsel or counsels (which will be limited to one counsel per
indemnified party). The indemnifying party will not be subject to any liability
for any settlement made without its consent, which consent will not be
unreasonably withheld.

               (d)  Contribution.
                    ------------

                   (i)   If the indemnification provided for in this Section 6
from the indemnifying party is unavailable to an indemnified party for any
losses, claims, damages, liabilities or expenses referred to therein, then the
indemnifying party, in lieu of indemnifying such indemnified party, will
contribute to the amount paid or payable by such indemnified party as a result
of such losses, claims, damages, liabilities or expenses in such proportion as
is appropriate to reflect the relative fault of the indemnifying party and
indemnified parties in connection with the actions that resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations; provided, however, that in no event will the liability
                          --------  -------
of any of the Investors for contribution under this Section 6(d) exceed the
proceeds received by such Investor from the sale of Registrable Securities under
the applicable Registration Statement. The relative fault of such indemnifying
party and indemnified parties will be determined by reference to, among other
things, whether any action in question, including any untrue or alleged untrue
statement of a material fact or omission or alleged omission to state a material
fact, has been made by, or relates to information supplied by, such indemnifying
party or indemnified parties, and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such action. The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages, liabilities and expenses referred to above will be deemed to
include, subject to the limitations set forth in Section 6(c) hereof, any legal
or other fees or expenses reasonably incurred by such indemnified party in
connection with any investigation or proceeding.

                 (iii)   The parties hereto agree that it would not be just and
equitable if contribution pursuant to this Section 6(d) were determined by pro
                                                                           ---
rata allocation or by any other method of allocation that does not take account
----
of the equitable considerations referred to in the immediately preceding
paragraph. No party guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Securities Act) will be entitled to contribution from
any party who was not guilty of such fraudulent misrepresentation.

                 (iii)   If indemnification is available under this Section 6,
the indemnifying parties will indemnify each indemnified party to the full
extent provided in

                                       5
<PAGE>

Section 6(a) and Section 6(b) hereof without regard to the relative fault of
said indemnifying party or indemnified party or any other equitable
consideration provided for in this Section 6(d).

        7.     Miscellaneous.
               -------------

               (a)  No Inconsistent Agreements. The Company will not hereafter

in this Agreement without providing for the granting of comparable rights to the
Investor in this Agreement or that contains provisions that conflict with the

               (b)  Amendments and Waivers. Except as otherwise provided herein,
