                         REGISTRATION RIGHTS AGREEMENT

         THIS REGISTRATION RIGHTS AGREEMENT ("Agreement") dated November 25,
1998 among DUALSTAR TECHNOLOGIES CORPORATION, a Delaware corporation having its
principal office at 11-30 47th Avenue, Long Island City, New York 11101 (the
"Corporation"); the stockholders of the Corporation set forth on Schedule 1
hereto (the "Stockholders"); and TECHNOLOGY INVESTORS GROUP, LLC, a Delaware
limited liability company ("TIG").

         WHEREAS, in connection with a Note Purchase Agreement dated the date
hereof (the "Note Purchase Agreement"), the Corporation has agreed to sell its
Subordinated Convertible Note to TIG (the "Note");

         WHEREAS, the Corporation has agreed to provide certain registration
rights under the Securities Act of 1933, as amended (the "Act");

         NOW, THEREFORE, in consideration of the foregoing premises and the
covenants and agreements contained herein, the parties agree as follows:

         1. Registration Rights.

         1.1. Piggyback Registration Rights.

                  1.1.1. Right to Piggyback. If the Corporation proposes to
register any shares of its common stock (or securities convertible into or
exchangeable or exercisable for common stock) (the "Common Stock") under the
Act (a "Proposed Registration") and the registration form to be used may be
used for the registration of the Registrable Securities as defined in Section
1.5.6 below (a "Piggyback Registration"), the Corporation will give prompt
written notice to all holders of Registrable Securities of its intention to
effect such a registration and will, subject to Section 1.1.2 below, include in
such Piggyback Registration all Registrable Securities with respect to which
the Corporation has received written requests for inclusion therein within
fifteen (15) days after receipt of the Corporation's notice; provided that, the
maximum number of Registrable Securities that may be registered by TIG pursuant
to any such Piggyback Registration (the "TIG Maximum") shall not exceed the
percentage of TIG's total Registrable Securities equal to the percentage that
the total number of shares offered by the Corporation in the Proposed
Registration bears to the total number of issued and outstanding shares of the
Corporation. In the case of an underwritten offering, Registrable Securities
with respect to which such request for registration has been received will be
registered by the Corporation pursuant to this Section 1 on the same terms and
subject to the same conditions applicable to the stock to be sold by the
Corporation or by other persons selling under such Proposed Registration.
Holders of Registrable Securities will be entitled to include shares pursuant
to this Section 1.1.1 in (A) demand registrations of any shareholder of the
Corporation, or (B) registrations of the Corporation, other than a registration
statement on Form S-4 or S-8.

                  1.1.2. Priority on Piggyback Registrations. If the managing
underwriter or underwriters advise the Corporation in writing that in its or
their opinion (with respect to which opinion, the Company shall act in good
faith), (i) the number of securities proposed to be sold in a Proposed
Registration exceeds the number which can be sold in such offering, the
Corporation will include in such registration the number of securities which,
in the opinion of such underwriter or underwriters, can be sold as follows: (A)
first, the shares of Common Stock the Corporation proposes to sell, (B) second,
the shares of Common Stock requested to be included in such registration
pursuant to a demand registration right, if any, (C) third, the Registrable
Securities requested to be included in such registration, pro rata among the
holders of Registrable Securities to be included therein, and (D) fourth, other
shares of Common Stock requested to be included in such registration, or (ii)
it is inadvisable to include any Registrable Securities in such a Proposed
Registration, then no Registrable Securities shall be included in any such
registration.

                  1.1.3 Registration on Request. If, pursuant to Section 1.1.2
above, the TIG Maximum is reduced by more than twenty-five percent (25%),
thereafter, TIG shall have the right to require the Corporation upon its
written request to effect the registration of any remaining Registrable
Securities owned by TIG ("Demand Registration"); provided that, (i) the
Corporation shall not be obligated to effect more than one Demand Registration;
(ii) the Corporation shall be entitled to postpone for a reasonable period (but
not exceeding 135 days) the filing of any registration statement otherwise
required to be filed pursuant to this Section 1.1.3 if the Corporation
determines, in its sole discretion, that such registration or offering pursuant
thereto could interfere with any financing, acquisition, corporate
reorganization, or other material transaction or event involving the
Corporation, or would require premature disclosure thereof; and (iii) the
Corporation shall not be required to file any such registration statement at
any time when the Corporation would be required to undergo an interim audit or
to prepare financial statements other than the regular quarterly or annual
statements in order to comply with the requirements of such registration
statement with respect to financial information.

                  1.1.4. Selection of Underwriters. If any Proposed
Registration is an underwritten offering, the Corporation will select a
managing underwriter or underwriters to administer the offering.

         1.2. Registration Procedures. With respect to any Piggyback
Registration or Demand Registration, the Corporation will, subject to Sections
1.1.2 and 1.1.3, as expeditiously as practicable:

                  1.2.1. prepare and file with the Commission a Registration
Statement which includes the Registrable Securities and use its best efforts to
cause such Registration Statement to become effective;


                  1.2.2. prepare and file with the Commission such amendments
and post-effective amendments to the Registration Statement as may be necessary
to keep the Registration Statement effective for a period of not less than
three (3) months (or such shorter period which 


                                       2
<PAGE>

will terminate when all Registrable Securities covered by such Registration
Statement have been sold or withdrawn, but not prior to the expiration of the
forty-day period referred to in Section 4(3) of the Act and Rule 174
thereunder, if applicable); cause the Prospectus to be supplemented by any
required Prospectus supplement; and cause such supplement to be filed pursuant
to Rule 424 under the Act;

                  1.2.3. furnish to any person holding Registrable Securities
included in such Registration Statement and the underwriter or underwriters, if
any, without charge, at least one copy of the Registration Statement and any
post-effective amendment thereto, upon request, and such number of conformed
copies thereof and such number of copies of the Prospectus (including the
preliminary Prospectus) and any amendments or supplements thereto, and any
document incorporated by reference therein, as such person or underwriter may
reasonably request in order to facilitate the disposition of the Registrable
Securities being sold by such person, (it being understood that the Corporation
consents to the use of the Prospectus and any amendment or supplement thereto
by each person holding Registrable Securities covered by the Registration
Statement and the underwriter or underwriters, if any, in connection with the
offering and sale of the Registrable Securities covered by the Prospectus or
any amendment or supplement thereto);

                  1.2.4. notify each person holding Registrable Securities
included in such Registration Statement, at any time when a Prospectus relating
thereto is required to be delivered under the Act, when the Corporation becomes
aware of the happening of any event as a result of which the Prospectus
included in such Registration Statement (as then in effect) contains any untrue
statement of a material fact or omits to state a material fact necessary to
make the statements therein not misleading and, as promptly as practicable
thereafter, prepare and file with the Commission and furnish a supplement or
amendment to such Prospectus so that, as thereafter delivered to the purchasers
of such Registrable Securities, such Prospectus will not contain any untrue
statement of a material fact or omit to state a material fact necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading;

                  1.2.5. make generally available to its security holders an
earnings statement satisfying the provisions of Section 11(a) of the Act no
later than ninety (90) days after the end of the twelve-month period beginning
with the first month of the Corporation's first fiscal quarter commencing after
the effective date of the Registration Statement, which statement shall cover
said twelve-month period; and

                  1.2.6. use its reasonable best efforts to obtain the 
withdrawal of any order suspending the effectiveness of the Registration
Statement.

         Each holder of Registrable Securities, upon receipt of any notice from
the Corporation of the happening of any event of the kind described in Section
1.2.4, will forthwith discontinue disposition of the Registrable Securities
until such holder's receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 1.2.4 or until it is advised in 

                                       3
<PAGE>

writing (the "Advice") by the Corporation that the use of the Prospectus may be
resumed, and has received copies of any additional or supplemental filings
which are incorporated by reference in the Prospectus, and, if so directed by
the Corporation, such holder will, or will request the managing underwriter or
underwriters, if any, to deliver to the Corporation (at the Corporation's
expense) 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. In the event the Corporation shall give any
such notice, the time periods mentioned in Section 1.2.2 shall be extended by
the number of days during the period from and including the date of the giving
of such notice to and including the date when each seller of Registrable
Securities covered by such Registration Statement shall have received the
copies of the supplemented or amended Prospectus contemplated by Section 1.2.4
or the Advice.

         1.3. Restrictions on Public Sale. Each person holding Registrable
Securities included in a Registration Statement, if requested by the managing
underwriter or underwriters of any underwritten Proposed Registration, agrees
not to effect any public sale or distribution of Registrable Securities under
the Act during the five (5) business days prior to and during the sixty-day
period beginning on the effective date of such Proposed Registration (except as
part of such Proposed Registration) (or such earlier time as all the shares of
Common Stock included in such Registration Statement have been disposed of
pursuant thereto).

         1.4. Registration Expenses. All of the costs and expenses of each
registration hereunder will be borne by the Corporation, including the fees and
expenses of counsel and accountants for the Corporation, and all other costs
and expenses of the Corporation incident to the preparation, printing and
filing under the Act of the Registration Statement (and all amendments and
supplements thereto) and furnishing copies thereof and of the Prospectus
included therein, and the costs and expenses incurred by the Corporation in
connection with the qualification of the Registrable Securities under the state
securities or "blue-sky" laws of various jurisdictions; provided that, the
Corporation shall not bear costs and expenses of any holders of Registrable
Securities, including, but not limited to, underwriters' commissions, brokerage
fees, transfer taxes, transaction fees, or the fees and expenses of any
counsel, accountants or other representatives retained by any holder.

         1.5. Indemnification.

                  1.5.1. Indemnification by the Corporation. The Corporation
agrees to indemnify, to the full extent permitted by law, each holder of
Registrable Securities, its officers and directors and each person who controls
such holder (within the meaning of either Section 15 of the Act or Section 20
of the Exchange Act), against all losses, claims, damages, liabilities and
expenses caused by any untrue or alleged untrue statement of a material fact
contained in any Registration Statement, Prospectus or preliminary Prospectus
or any omission or alleged omission to state therein a material fact necessary
to make the statements therein (in the case of the Prospectus or any
preliminary Prospectus, in light of the circumstances under which they were
made) not misleading, except insofar as the same are caused by or contained in
any information with respect 


                                       4
<PAGE>

to such holder furnished in writing to the Corporation by or on behalf of such
holder for use therein or by such holder's failure to deliver a copy of the
Registration Statement or Prospectus or any amendments or supplements thereto
after the Corporation has furnished such holder with a sufficient number of
copies of the same.

                  1.5.2. Indemnification by Holders of Registrable Securities.
In connection with any Registration Statement in which a holder of Registrable
Securities is participating, each such holder will furnish to the Corporation
in writing such information and affidavits with respect to such holder as the
Corporation reasonably requests for use in connection with any Registration
Statement or Prospectus and agrees to indemnify, to the full extent permitted
by law, the Corporation, its directors and officers and each person who
controls the Corporation (within the meaning of either Section 15 of the Act or
Section 20 of the Exchange Act) against any losses, claims, damages,
liabilities and expenses resulting from any untrue or alleged untrue statement
of a material fact or any omission or alleged omission to state a material fact
necessary to make the statements in the Registration Statement or Prospectus or
preliminary Prospectus (in the case of the Prospectus or any preliminary
Prospectus, in light of the circumstances under which they were made) not
misleading, to the extent that such untrue statement or omission is contained
in any information or affidavit with respect to such holder so furnished in
writing by or on behalf of such holder for inclusion in any Prospectus or
Registration Statement. The Corporation shall be entitled to receive
indemnification from underwriters, selling brokers, dealer managers and similar
securities industry professionals participating in the distribution, to the
same extent as provided above with respect to information with respect to such
persons so furnished in writing by such persons specifically for inclusion in
any Prospectus or Registration Statement.

                  1.5.3. Conduct of Indemnification Proceedings. Any person
entitled to indemnification hereunder will (i) give prompt written notice to
the indemnifying party of any claim with respect to which it seeks
indemnification, and (ii) unless in the indemnifying party's reasonable
judgment a conflict of interest may exist between such indemnified and
indemnifying parties with respect to such claim, permit such indemnifying party
to assume the defense of such claim with counsel reasonably satisfactory to the
indemnified party. Whether or not such defense is assumed by the indemnifying
party, the indemnifying party will not be subject to any liability for any
settlement made without its consent. No indemnifying party will consent to
entry of any judgment or enter into any settlement which does not include as an
unconditional term thereof the giving by the claimant or plaintiff to such
indemnified party of a release from all liability in respect of such claim or
litigation. An indemnifying party who is not entitled to, or elects not to,
assume the defense of a claim will not be obligated to pay the fees and
expenses of more than one counsel for all parties indemnified by such
indemnifying party with respect to such claim, unless in the reasonable
judgment of the indemnifying party a conflict of interest may exist between
such indemnified party and any other of such indemnified parties with respect
to such claim, in which event the indemnifying party shall be obligated to pay
fees and expenses of such additional counsel or counsels.


                                       5
<PAGE>

                  1.5.4. Contribution. If for any reason the indemnification
provided for in Sections 1.5.2 and 1.5.3, respectively, is unavailable to an
indemnified party, then the indemnifying party shall contribute to the amount
paid or payable by the indemnified party as a result of such loss, claim,
damage or liability in such proportion as is appropriate to reflect the
relative fault of the indemnified party and the indemnifying party, as well as
any other relevant equitable consideration. The relative fault of such
indemnifying party and indemnified parties shall be determined by reference to,
among other things, whether any action in question, including any untrue and
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 a party as a result of the losses,
claims, damages, liabilities and expenses referred to above shall be deemed to
include, subject to the limitations set forth in Section 1.5.3, any legal or
other fees or expenses reasonably incurred by such party in connection with any
investigation or proceeding.

         The parties hereto agree that it would not be just and equitable if
contribution pursuant to this Section 1.5.4 were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to in the immediately preceding
paragraph. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

                  1.5.5. Participation in Underwritten Registrations. No holder
of Registrable Securities may participate in any underwritten registration
hereunder unless such holder (i) agrees to sell its Registrable Securities on
the basis provided in any underwriting arrangements, and (ii) completes and
executes all questionnaires, powers of attorney, underwriting agreements and
other documents customarily required under the terms of such underwriting
arrangements.

                  1.5.6. Definitions. "Registrable Securities" means the shares
of DualStar Technologies Corporation Common Stock held by the Stockholders or
issued upon conversion of the Note and held by TIG, only so long as any share
of Common Stock continues to be a "Restricted Security." A share shall be
deemed to be a Restricted Security (i) until such share has been effectively
registered under the Act, or (ii) unless such share may be sold pursuant to
Rule 144(k) (or any similar provision then in force) under the Act.

                  1.5.7. Amendments and Waivers. Nothing contained herein shall
alter, modify or affect anything contained in the Stockholders Agreement dated
the date hereof. The provisions of this Section 1, including the provisions of
this sentence, may not be amended, modified or supplemented, and waivers of or
consents to departures from the provisions hereof may not be given unless the
Corporation has obtained the written consent of entities or individuals holding
more than fifty percent (50%) of the outstanding Registrable Securities.

                                       6
<PAGE>

                  1.5.8. Termination. This Section 1 shall continue in full
force and effect until none of the shares are Registrable Securities; provided,
however, that the rights set forth in this Section 1 shall only inure to the
benefit of the Stockholders and TIG.

         2. Miscellaneous.

         2.1. Governing Law. The interpretation and construction of this
Agreement, and all matters relating hereto, shall be governed by the laws of

this Agreement.

         2.3. Publicity. None of the parties hereto shall issue any press
release or make any other public statement, in each case relating to or
connected with or arising out of this Agreement or the matters contained
herein, without obtaining the prior approval of the other parties to the
contents and the manner of presentation and publication thereof, except such
reports or other notices that the party issuing or making same has been advised
by counsel are required pursuant to applicable law or regulation.

         2.4. Notices. Any notice required hereunder shall be in writing and
shall be sufficiently given if delivered or sent by reputable overnight courier
or facsimile transmission (in each case with evidence of receipt), addressed to
the Corporation at its principal office first set forth above, and to the
Stockholders and TIG, respectively, at the addresses set forth on Schedule 1
hereto. Any party may change such address by like notice. If sent by courier,
such notice shall be deemed to have been given as of the next business day
after it was deposited with the courier service and if sent by facsimile such
notice shall be deemed to have been given when transmitted.

         2.5. Parties in Interest. Subject to Sections 1.5.7 and 1.5.8 above,
this Agreement shall not be assignable or transferable by any of the parties.

         2.6. Counterparts. This Agreement may be executed in two or more
counterparts, all of which taken together shall constitute one instrument.

         2.7. Entire Agreement. This Agreement, including the other documents
referred to herein which form a part hereof, contains the entire understanding
of the parties hereto with respect to the subject matter contained herein and
therein. This Agreement supersedes all prior agreements and understandings
between the parties with respect to such subject matter.

                                       7

         IN WITNESS WHEREOF, each of the Corporation and TIG has caused this
Agreement to be executed by its officer thereunto duly authorized, and each of
the Stockholders has executed this Agreement, all as of the day and year first
above written.
