                            APOGEE TECHNOLOGY, INC.
                         STOCK SUBSCRIPTION AGREEMENT

Apogee Technology, Inc.
129 Morgan Avenue
Norwood, MA  02760

Ladies and Gentlemen:

      Subject to the terms and conditions set forth below, the undersigned
hereby offers to purchase from Apogee Technology, Inc., a Delaware corporation
(the "Company"), ____ units (the "Securities"), each unit consisting of one (1)
share of the Company's Common Stock, par value $.01 per share, and a right to
purchase one-fifth (1/5) of a share of Common Stock, for the aggregate purchase
price of $______ in cash ($2.00 per unit), which accompanies this Agreement.
Attached hereto is a form of warrant which will be issued to the undersigned to
evidence the aggregate rights to be received along with the unit shares.

      In connection with the execution of this Agreement and to induce the
Company to sell the Securities to the undersigned, the undersigned hereby
represents, warrants and agrees as follows:

      1. Accredited Investor. I am an "accredited investor" as such term is
defined in Regulation D under the Securities Act of 1933, as amended (the
"Securities Act"), for the following reason (Please initial one or more):

      ___   My individual income was in excess of $200,000 in each of the past
            two years, or my joint income with my spouse was in excess of
            $300,000 in each of those years, and I reasonably expect my income
            to reach the same level in the current year.

      ___   My individual net worth or joint net worth with my spouse exceeds
            $1,000,000.

      ___   The undersigned is a trust, corporation or partnership with total
            assets in excess of $5,000,000, not formed for the specific purpose
            of acquiring the Securities, whose purchase of the Securities will
            be directed by a person whose knowledge and experience in financial
            and business matters is such that he or she is capable of evaluating
            the merits and risks of the investment in the Securities.

      ___   The undersigned is an entity in which all of the equity owners are
            accredited investors.

      ___   Other (Please specify): ___________________________________________

      2. Experience and Suitability. I am qualified by my knowledge and
experience in financial and business matters to evaluate the merits and risks of
an investment in the Securities and to make an informed decision relating
thereto. I have the financial capability for making the

<PAGE>

investment and protecting my interests, and I can afford a complete loss of the
investment. The investment is a suitable one for me.

      3. No Need for Liquidity. I am aware that I will be unable to liquidate my
investment readily in case of an emergency and that the Securities being
purchased may have to be held for an indefinite period of time. My overall
commitment to investments which are not readily marketable is not excessive in
view of my net worth and financial circumstances and the purchase of the
Securities will not cause such commitment to become excessive. In view of such
facts, I acknowledge that I have adequate means of providing for my current
needs, anticipated future needs and possible contingencies and emergencies and
have no need for liquidity in the investment in the Securities. I am able to
bear the economic risk of this investment.

      4. Opportunity to Investigate. Prior to the execution of this Agreement,
my advisors and I have had the opportunity to ask questions of, and receive
answers from, representatives of the Company concerning the terms and conditions
of this transaction, and the finances, operations, business and prospects of the
Company. My advisors and I have also had the opportunity to obtain additional
information necessary to verify the accuracy of information furnished about the
Company. Accordingly, I have independently evaluated the risks of purchasing the
Securities, and I am satisfied that I have received information with respect to
all matters which I consider material to my decision to make this investment.

      5. Investment Purpose. I am acquiring the Securities for my own account
for the purpose of investment and not with a view to, or for resale in
connection with, the distribution thereof, nor with any present intention of
distributing or selling the Securities. I understand that the Securities have
not been registered under the Securities Act or the securities laws of any
state, and I hereby agree not to make any sale, transfer or other disposition of
any such Securities unless either (i) the Securities first shall have been
registered under the Securities Act and all applicable state securities laws, or
(ii) an exemption from such registration is available, and the Company has
received such documents and agreements from me and the transferee as the Company
requests at such time.

      6. Legends. I understand that until the Securities have been registered
under the Securities Act and applicable state securities laws each certificate
representing such securities shall bear a legend substantially similar to the
following:

            The securities represented by this certificate have not been
            registered under the Securities Act of 1933, as amended (the "Act"),
            or any state securities laws, have been acquired for investment, and
            may not be sold, pledged, hypothecated or otherwise transferred
            unless a registration statement under the Act and applicable state
            law is in effect with regard thereto or unless an exemption from
            such registration is available.

      7. No Regulatory Approval of Merits. I understand that neither the
Securities and


                                     - 2 -

<PAGE>

Exchange Commission nor the commissioner or department of securities or attorney
general of any state has passed upon the merits or qualifications of, nor
recommended nor approved, the Securities. Any representation to the contrary is
a criminal offense.

      8. Independent Advice. I understand that I am urged to seek independent
advice from my professional advisors relating to the suitability for me of an
investment in the Company in view of my overall financial needs and with respect
to the legal and tax implications of such an investment.

      9. Indemnification. I understand the meaning and legal consequences of
this Agreement and agree to indemnify and hold harmless the Company and each
director and officer thereof from and against any and all loss, damage or
liability due to or arising out of a breach of any representation, warranty or
agreement of the undersigned contained in this Agreement.

      10. Authority and Noncontravention. The execution and performance hereof
violates no order, judgment, injunction, agreement or controlling document to
which the undersigned is a party or by which the undersigned is bound. If an
organization, (i) the undersigned is duly organized, validly existing and in
good standing under the laws of the jurisdiction in which it has been formed;
(ii) the undersigned has the right and power under its organizational
instruments to execute, deliver and perform its obligations hereunder; and (iii)
this Agreement has been duly authorized by all necessary action on the part of
all officers, directors, partners, stockholders and trustees and will not
violate any agreement to which the undersigned is a party; and (iv) the
individual executing and delivering this Agreement has the requisite right,
power, capacity and authority to do so on behalf of the organization. The
undersigned has not been organized for the purpose of subscribing for the
Securities.

      11. Duration. I understand that I may not cancel, terminate or revoke this
Agreement or any agreement made by me hereunder and that this Agreement shall
survive my death or disability and shall be binding upon my heirs, executors,
administrators, successors and assigns.

      12. Further Assurances. Within ten (10) days after receipt of a written
request from the Company, I agree to provide such information and to execute and
deliver such documents as reasonably may be necessary to comply with any and all
laws and ordinances to which the Company is subject.

      such notice or demand to any other or further notice or demand in similar

      warrants to the other that no broker, finder or other financial consultant
      has acted on its behalf in connection with this Agreement or the
      transactions contemplated hereby in such a way as to create any liability
      on the part of the other. Each of the parties hereto agrees to indemnify
      and save the other harmless from any claim or demand for commission or
