2.3   RIGHT OF FIRST REFUSAL - HOLDINGS

      (a)   Subject to Section 2.2, if the Investor desires to sell any or all

            fide irrevocable written offer from a Person dealing at arms' length
            (within the meaning of the Income Tax Act (Canada)) with the
            Investor (in this section the "THIRD PARTY") to purchase any or all
            of the Shares held by the Investor (in this section the "THIRD PARTY
            OFFER"), then it shall first offer to sell (the "OFFER") all, but

                  copy of the Third Party Offer, and reasonable detail as to the
                  identity and, where applicable, the ownership of the Third
                  Party, and the terms and conditions of the Offer shall be not
                  less favorable, in the aggregate, for the Notified Parties
                  than those contained in the Third Party Offer;

            (ii)  in the case of a an Investor Offer, the sale price in the
                  Offer shall be the Value of the Offered Securities as at the
                  last day of the Corporation's most recently-completed fiscal
                  year, or as otherwise determined pursuant to Section 2.11
                  hereof; and

            (iii) in all cases, the Offer shall be open for acceptance by the
                  Notified Parties for twenty (20) Business Days (the "OFFER
                  PERIOD") from the receipt of the Offer by the Notified
                  Parties.

            The Notified Parties shall be obliged by delivering notice to the
            Investor within, but not after the expiration of, the Offer Period
            at their sole option to either accept the Offer or reject the Offer.
            If a Notified Party does not accept the Offer, then such Notified
            Party shall be deemed to have rejected the Offer. If a Notified
            Party has accepted the Offer, then the Investor shall sell to the
            Notified Party, and the Notified Party shall purchase from the
            Investor, the Offered Securities in accordance with this Agreement.
            If both Notified Parties accept the Offer, the Offered Securities
            shall be sold to the Corporation.

      (b)   If both of the Notified Parties have or are deemed to have rejected
            the Offer, then the Investor shall be free for a period of thirty
            (30) Business Days immediately following the last day of the Offer
            Period to sell all, but not less than all, of the Offered Securities

            (i)   in the case of a Third Party Offer, to the Third Party on
                  terms not more favorable in the aggregate for the Third Party
                  than those contained in the Third Party Offer; or

            (ii)  in the case of an Investor Offer, to any Person on terms not
                  more favorable, in the aggregate, for such Person than those
                  contained in the Offer;

                                      -7-

            provided, however, that in either case it shall be a condition
            precedent to the right of the Investor to sell the Offered
            Securities that the purchaser has executed a counterpart of this
            Agreement in accordance with Section 8.5. If no sale takes place
            within the said thirty (30) Business Day period, then the Investor

following the last day of the Offer Period (as defined in Section 3.4(a) of the
Management Shareholders' Agreement).

      Holdings shall provide the Investor with any and all notices it provides
to or receives from the Management Investors under Section 3.4 of the Management
Shareholders' Agreement no later that one (1) Business Day after Holdings sends
or receives such notice. The Investor shall exercise its rights under this
Section 2.3 by notifying Holdings and the Corporation in writing within twenty
(20) Business Days of the Investor's receipt of the Offer (as defined in Section
3.4(a) of the Management Shareholders' Agreement) which Offer shall be sent to
the Investor by Holdings as if the Investor were a Management Investor as
provided in Section 3.4 of the Management Shareholders' Agreement.

      If the Investor does not elect to purchase the Offered Securities (as
defined in Section 3.4(a) of the Management Shareholders' Agreement) as provided
in this Section 2.4, then Holdings shall be free to sell all of such Offered
Securities in accordance with Section 3.4(d) of the Management Shareholders'
Agreement, provided that it shall be a condition precedent to the right of
Holdings to sell the Offered Securities (as defined in Section 3.4(a) of the
Management Shareholders' Agreement, that the purchaser has executed a
counterpart of this Agreement in accordance with Section 8.5. If no sale takes
place within the period set forth in Section 3.4(d) of the Management
Shareholders' Agreement, then Holdings shall not transfer the Offered Securities
(as defined in Section 3.4(a) of the Management Shareholders' Agreement),
without again following and being subject to this Article II.

2.5   DRAG ALONG RIGHTS

      If Holdings (and/or its Permitted Transferees) holds, in the aggregate,
not less than seventy-five percent (75%) of the outstanding Shares and it
receives a bona fide irrevocable written offer (in this section the "THIRD PARTY
OFFER") from a Person dealing at arms' length (within the meaning of the Income
Tax Act (Canada)) with Holdings (in this section the "THIRD PARTY"), to purchase
all (but not less than all) of the Shares held by Holdings (and its Permitted
Transferees), which it has accepted or intends to accept, then Holdings shall
have the right, upon written notice to the Investor, to require that the
Investor sell all of the Shares held by the

                                      -8-
<PAGE>

Investor together with the Shares held by Holdings on the same terms as those
contained in the Third Party Offer. In such event, the Investor shall be obliged
to sell all of the Shares held by it in accordance with the terms of the Third
Party Offer.

2.6   TAG ALONG RIGHTS

      If Holdings (and its Permitted Transferees) holds, in the aggregate, not
less than fifty percent (50%) of the outstanding Shares and it receives a bona
fide irrevocable written offer (in this section the "THIRD PARTY OFFER") from a
Person dealing at arms' length (within the meaning of the Income Tax Act
(Canada)) with Holdings (in this section the "THIRD PARTY") to purchase any or
all of the Shares held by Holdings (and/or its Permitted Transferees), which it
has accepted or intends to accept, Holdings shall so notify the Investor in
writing, setting forth the terms of the Third Party Offer, including the name of
the Third Party, the number of Shares Holdings (and/or its Permitted
Transferees) intend to sell to the Third Party (in this section the "OFFERED
SECURITIES") and the material terms of the sale, including the price per Share
and the expected Closing Date. The Investor shall have the right, upon written
notice to Holdings sent within ten (10) days of Investor's receipt of the notice
from Holdings, to require the Third Party (or the Management Investors,
exercising their rights under the Management Shareholders' Agreement) to acquire
from the Investor (rather than from Holdings) a number of Shares equal to the
product of the number of Offered Securities multiplied by a fraction, the
numerator of which is the number of Shares owned by the Investor and the
denominator of which is the number of Shares owned by Holdings (and its
Permitted Transferees). Any Shares sold by the Investor hereunder shall be sold
on the same terms as those contained in the Third Party Offer.

2.7   REFUSAL OF CORPORATION

      The Corporation shall record each transfer of Shares; provided, however,
that the Corporation shall refuse to record a transfer of Shares made in
contravention of this Agreement. The Corporation and its board of directors,
prior to consenting to the transfer of Shares, shall be entitled to require
proof that the transfer took place in accordance with this Agreement.

2.8   OFFER; THIRD PARTY OFFER NOTICE

      Each Offer and Third Party Offer Notice shall be in writing signed by the
offering party and shall:

      (a)   identify the Section pursuant to which it is delivered;

      (c)   state the purchase price per Offered Security;

            party within the meaning of the Income Tax Act (Canada)) to whom it
            proposes to sell the Offered Securities;

      (e)   in the case where a Third Party Offer is made, the Offer or Third
            Party Offer Notice shall be accompanied by a true copy of the Third
            Party Offer;

                                      -9-
<PAGE>

      (f)   in the case where a Third Party Offer is made, be accompanied by an
            affidavit of the offering party attesting that there is no
            commission or similar fee that may be or may become due and payable
            to any broker, agent or other intermediary in connection with the
            sale of the Offered Securities; and

      (g)   in the case of an Offer, be accompanied by the certificate or
            certificates representing the Offered Securities.

2.9   IRREVOCABILITY

      All Offers and Third Party Offer Notices and their acceptance, rejection
or deemed acceptance or rejection are irrevocable.

2.10  INSCRIPTION

      The Corporation shall cause, and the Shareholders shall vote their Shares
to cause the Corporation to cause, all certificates for Shares to be endorsed
with the following inscription:

      "OWNERSHIP, ALIENATION AND ENCUMBRANCE OF THE SECURITIES REPRESENTED BY
      THIS CERTIFICATE ARE SUBJECT TO THE TERMS OF THE SHAREHOLDERS' AGREEMENT
      MADE AS OF AUGUST 15, 2002 AS AMENDED, A COPY OF WHICH IS ON FILE AT THE
      REGISTERED OFFICE OF THE CORPORATION."

2.11  DETERMINATION OF VALUE

      The auditors of the Corporation or a nationally recognized valuation or
investment banking firm (the "AUDITORS") shall determine the Value of a Share at
least once in every fiscal year of the Corporation and, in any event, they shall
determine the Value as at the last day of each fiscal year of the Corporation.
In the event that, at the time a Value must be attributed to Shares for purposes
of any of the provisions of this Article II or Section 3.1, the Value has not
been determined by the Auditors as at the last day of the most recently
completed fiscal year of the Corporation, then the Closing of the relevant
transaction shall be deferred until such Value has been determined, and it is
such Value which shall be applied to such transaction.

      Notwithstanding the foregoing, in the event that, at the time that a Value
must be attributed to Shares for purposes of any of the provisions of this
Article II or Section 3.1, more than three (3) months have passed since the date
as of which the Value of the Shares was last determined by the Auditors, the
Investor who is selling Shares pursuant to this Article III shall be entitled to
require a new valuation of the Shares, in which case the Auditors shall
determine the Value of the Shares as at the last day of the most
recently-completed month-end of the Corporation, and all costs, fees and
expenses of such valuation shall be borne equally by the Investor and the
Corporation.

      The standard for determining Value shall be the highest price available in
an open and unrestricted market between informed, prudent parties acting at
arm's length and under no compulsion to act, expressed in terms of money. In
furtherance of the foregoing, in determining the Value for the Shares, no
discount shall be taken with respect to any Shares by virtue of the fact that
they lack marketability, are not freely transferable or that they represent a
minority

                                      -10-
<PAGE>

interest in the Corporation, nor shall any premium be attributable to any freely
transferable Shares or Shares that are part of a controlling interest in the
Corporation.

      In the event that the outstanding Shares shall be subdivided into a
greater or lesser number of Shares, whether by stock dividend, stock split or
combination of Shares, subsequent to the date as of which the Value is
determined but prior to any Closing pursuant to Article V occasioned by any
event described in Article II or III, the Value for purposes of Articles II, III
and V shall be proportionately decreased or increased as the case may be and the
number of Shares to be sold or purchased shall be adjusted so as to
appropriately reflect such stock dividend, split, subdivision or combination. No
such adjustment shall be made, however, by reason of the issuance of Shares for
cash, property or services, by way of stock options, stock warrants,
subscription rights or otherwise.

                                  ARTICLE III
                                   CONVERSION

3.1   CONVERSION PRIVILEGE

      (a)   In the event that the Corporation does not issue and does not intend
            to issue shares of its share capital to the general public and
            Holdings intends to issue shares in its share capital to the general
            public and such offering subsequently occurs, then the Investor
            shall have the right and option (exercised by written notice to
            Holdings) to cause Holdings to exchange the Shares held by the
            Investor for securities in the share capital of Holdings, which
            securities shall have a value (without reference to their proposed
            issue price) identical to the value of the Shares held by the
            Investor. In the event of any dispute between Holdings and the
            Investor as to the number or value of the securities in the share
            capital of Holdings to be issued in accordance herewith (or anything
            incidental thereto), such number shall be absolutely determined by
            an Auditor to be designated by Holdings with the approval of the
            Investor, whose determination shall be final and binding on the
            parties hereto, to the complete exclusion of any court or trial. The
            standard for determining value shall be the highest price available
            in an open and unrestricted market between informed, prudent parties
            acting at arm's length and under no compulsion to act, expressed in
            terms of money.

      (b)   Holdings agrees that its rights and obligations under Articles III
            and VI hereof shall be assumed by any other issuer of securities
            into which all or substantially all of the equity securities of
            Holdings are directly or indirectly converted or exchanged if such
            issuer has securities which have been sold to the general public or
            if such issuer intends to issue such securities to the general
            public and such offering subsequently occurs. Such other issuer
            shall expressly acknowledge its obligations under Articles III and
            VI in connection with any such conversion or exchange by Holdings
            with such issuer.

<PAGE>

3.2   NO FRACTIONAL SHARES

      Notwithstanding anything herein contained, Holdings shall in no case be
required to issue fractional securities upon the conversion of the Shares. If
any fractional share would, except for this Section 3.2, be deliverable upon the
conversion of the Shares, Holdings shall satisfy all of its obligations under
this Agreement with respect to such fractional share by paying to the
Shareholder an amount in cash equal (to the nearest cent) to the value of the
fractional share.

      In determining the value, no discount shall be taken with respect to any
securities by virtue of the fact that they lack marketability, are not freely
transferable or represent a monetary interest in the issues nor shall any
premium be attributable to any freely transferable securities or securities that
are part of a controlling interest in the applicable issuer.

                                   ARTICLE IV
                                PREEMPTIVE RIGHTS

4.1   PREEMPTIVE RIGHTS

      If the Corporation proposes to sell additional equity securities other
than (a) to employees of the Corporation pursuant to employee benefit plans and
other employee compensation plans approved by the Board, (b) pursuant to an
acquisition or business combination approved by the Board, (c) in an offering
registered under the US Securities Act of 1933, as amended or qualified for sale
under the securities laws of any province of Canada, or (d) in connection with
the exercise, exchange or conversion of securities of the Corporation, the
Investor shall have the right to purchase up to such Shareholder's "pro rata
share" of such additional securities. The Investor's "pro rata share" shall be
that number of additional securities that would result in the Investor owning
the same percentage of the Corporation's fully diluted shares (assuming all
convertible securities or instruments were converted into Common Shares or
Non-Voting Common Shares) after the issuance of the additional securities (the
"ISSUANCE") as the Investor owned immediately prior to the Issuance. In the
event of a proposed Issuance, the Corporation shall deliver to the Investor
written notice describing the proposed Issuance, specifying the Investor's pro
rata share and stating the purchase price for the additional securities, and the
date, time and place of settlement for payment for the additional securities
(which shall be no sooner than twenty-five (25) Business Days following the date
of the notice). For a period of twenty (20) Business Days following such notice,
the Investor shall have the right to subscribe, at the offering price
established by the Corporation, by written notice to the Corporation, to
purchase all or any portion of the Investor's pro rata share of the additional
securities. Following such twenty (20) Business Day period, the Corporation
shall be free for a period of ninety (90) Business Days thereafter to sell all
or any part of the unsubscribed for additional securities and any Shares that
have not been purchased as of the applicable Closing Date at a price no more
favorable to such purchasers than the price offered to the Investor

5.1   TIME, PLACE, TERMS AND CONDITIONS

      (a)   Each Closing shall be held at the registered office of the
            Corporation at 10:00 a.m. (Montreal, Canada time) on the Closing

                  be accompanied by a duly executed assignment of the Shares to
                  the purchaser; and

            (ii)  payment for Shares shall be made in full at Closing.

      (b)   At Closing, the selling shareholder shall deliver to the purchaser a
            written warranty that:

            (i)   there are no contractual or other restrictions on the transfer
                  of the purchased Shares (other than the restrictions set out
                  in the Articles of the Corporation and in this Agreement); and

            (ii)  the selling shareholder is the sole beneficial owner of the
                  purchased Shares with full right, title and authority to
                  transfer the purchased Shares to the purchaser, free and clear
                  of all claims, liens and other encumbrances whatsoever.

      (c)   At Closing, all necessary and proper corporate proceedings required
            by counsel for the purchaser, acting reasonably, shall be taken for
            the transfer of the purchased Shares.

      (d)   If the purchaser fails for any reason whatsoever to proceed with
            Closing or to pay to the selling shareholder any amount due
            hereunder, then all amounts due hereunder but not paid shall bear
            interest from the date of Closing until paid in full at a rate of
            interest per annum equal to the Prime Rate plus three percent (3%).
            Such interest shall be payable on demand.

      The conditions set forth in this Section 5.1 are each made for the
exclusive benefit of the purchaser and if any such conditions is not satisfied
at the Closing, then the purchaser may, at its option, either refuse to proceed

such condition not being satisfied.

Closing, shall do, execute, acknowledge and deliver or cause to be done,
executed, acknowledged or delivered all such further acts, deeds, documents,
assignments, transfers, conveyances, powers of attorney and assurances as may be
reasonably necessary or desirable to effect complete consummation of the
transactions contemplated by this Agreement.

                               REGISTRATION RIGHTS

6.1   REGISTRATION RIGHTS

      (a)   The Investor shall have the registration rights described in Exhibit
            A attached hereto which shall be deemed an integral part hereof with
            respect to any Shares now or hereafter acquired by the Investor,
            including Shares acquired upon the conversion of the Preferred
            Shares, Shares acquired upon conversion of the Notes and Shares
            acquired by the Investor under Articles II, III or IV, or otherwise.

      (b)   Notwithstanding anything herein to the contrary, and without

            applicable Law, if at any time after the date hereof, there shall be
            (i) any reclassification, recapitalization or other change of the
            outstanding Shares (other than as a result of a subdivision or
            combination thereof), (ii) any consolidation, combination,
            amalgamation, merger or similar transaction of the Corporation with
            any other entity (other than a merger in which the Corporation is
            the surviving or continuing entity and its capital stock is
            unchanged) in which the Shares are converted into any other
            securities or (iii) any share exchange or similar transaction
            pursuant to which the outstanding Shares are converted into other
            securities, then the registration rights of the Investor as set
            forth in Exhibit A shall be deemed to apply to the securities
            received by the Investor in or as a consequence of such transaction
            and the issuer of such securities shall expressly acknowledge its
            obligations under this Article VI.

                       CORPORATE GOVERNANCE AND COVENANTS

7.1   BOARD OF DIRECTORS

      From and after the date hereof, Holdings agrees to vote (including by
execution of a written consent or in any other manner permitted by Law and the

7.2   RIGHT OF INSPECTION

      So long as the Investor owns any Shares or any securities or instruments
convertible into or exchangeable for Shares, the Investor and its
representatives and agents (collectively, the "INSPECTORS") shall have the right
at the Investor's expense, to visit and inspect any of the properties of the
Corporation and its subsidiaries, to examine the books of account and records of
the Corporation and its subsidiaries, to make or be provided with copies and
extracts therefrom, to discuss the affairs, finances and accounts of the
Corporation and its subsidiaries with, to be advised as to the same by, its and
their officers, and independent public accountants (and by this provision the
Corporation authorizes such accountants to discuss such affairs, finances and
accounts, whether or not a representative of the Corporation is present) all at
such reasonable times and intervals and to such reasonable extent as such
Investor may desire; provided, however, that each Inspector shall hold in
confidence and shall not make any disclosure (except to the Investor) of any
such information which the Corporation determines in good faith to be
confidential, and of which determination the Inspectors are so notified, unless
(a) the release of such information is ordered pursuant to a subpoena or other
order form a court or government body of competent jurisdiction, or (b) such
information to any Inspector until and unless such Inspector shall have entered
into confidentiality agreements (in form and substance satisfactory to the
Corporation) with the Corporation with respect thereto. The Investor agrees that
it shall, upon learning that disclosure of such information is sought in or by a
court or governmental body of competent jurisdiction or through other means,
give prompt notice to the Corporation and allow the Corporation, at its expense,
to undertake appropriate action to prevent disclosure of, or to obtain a
protective order for, the information deemed confidential. Notwithstanding the
first sentence of this Section 7.2, the Corporation shall bear the costs of
Investor's expenses under this section 7.2 after and during the continuance of
any Event of Default as defined in the Notes. Notwithstanding the foregoing, the
Corporation shall be entitled to restrict the rights of inspection granted to
the Investors hereunder and shall not be required to disclose to the Investors
any information where the Corporation deems in good faith that the exercise of
such inspection rights or the disclosure of such information would entail
disclosure of a trade secret or other confidential information of the
Corporation or information of a commercially sensitive nature the disclosure of
which would be detrimental to the Corporation or its business.

in good faith to be a trade secret or similar confidential information.

7.4   COVENANTS

      So long as the Investor owns Preferred Shares, Notes and Shares which on
an as-converted basis equal the Minimum Number of Shares, the Corporation agrees
to take the actions listed below.

      (a)   The Corporation will promptly pay and discharge, or cause to be paid
            and discharged when due and payable, all lawful taxes, assessments,
            and governmental charges or levies imposed upon the income, profits,
            property, or business of the Corporation or any subsidiary;
            provided, however, that any such tax, assessment, charge, or levy
            need not be paid if the validity hereof shall currently be contested
            in good faith by appropriate proceedings and if the Corporation
            shall have set aside on its books adequate reserves with respect
            thereof, and provided further, that the Corporation will pay all
            such taxes, assessments, charges, or levies forthwith upon the
            commencement of proceedings to foreclose any lien that may have
            attached as security therefor. The Corporation will promptly pay or
            cause to be paid when due, or in conformance with customary trade
            terms, all other indebtedness incident to the operations of the
            Corporation.

      (b)   The Corporation will keep its properties and those of its
            subsidiaries in good repair, working order, and condition,
            reasonable wear and tear excepted, and from time to time make all
            needful and proper repairs, renewals, replacements, additions, and
            improvements thereto; and the Corporation and its subsidiaries will
            at all times comply with the provisions of all material leases to
            which any of them is a party or under which any of them occupies
            property so as to prevent any loss or forfeiture thereof or
            thereunder.

      (c)   Except as otherwise decided in accordance with policies adopted by
            the Board, the Corporation will keep its assets and those of its
            subsidiaries that are of an insurable character insured by
            financially sound and reputable insurers against loss or damage by
            fire, extended coverage, and explosion insurance in amounts
            customary for companies in similar businesses similarly situated;
            and the Corporation will maintain, with financially sound and
            reputable insurers, insurance against other hazards, risks, and
            liabilities to persons and property to the extent and in the manner
            customary for companies in similar businesses similarly situated.

      (d)   The Corporation and all of its subsidiaries will keep records and
            books of account in which full, true, and correct entries will be
            made of all dealings or transactions in relation to its business and
            affairs in accordance with GAAP applied on a consistent basis.

      (e)   The Corporation and all its subsidiaries shall duly observe and
            conform to all valid requirements of governmental authorities
            relating to the conduct of their businesses or to their properties
            or assets.

                                      -17-
<PAGE>

      (f)   The Corporation shall maintain in full force and effect its
            corporate existence, rights, and franchises and all licenses and
            other rights to use patents, processes, licenses, trademarks, trade
            names, or copyrights owned or possessed by it or any subsidiary and
            deemed by the Corporation to be necessary to the conduct of its
            business.

      (g)   The Corporation will retain independent public accountants of
            recognized national standing who shall certify the Corporation's
            financial statements at the end of each fiscal year. In the event
            the services of the independent public accountants so selected, or
            any firm of independent public accountants hereafter employed by the
            Corporation are terminated, the Corporation will promptly thereafter
            notify the Investor and will request the firm of independent public
            accountants whose services are terminated to deliver to the
            Investors a letter from such setting forth the reasons for the
            termination of their services. In the event of such termination the
            Corporation will promptly thereafter engage another firm of
            independent public accountants of recognized national standing. In
            its notice to the Investor the Corporation shall state whether the
            change of accountants was recommended or approved by the Board of
            Directors of the Corporation or any committee thereof.

                                                     Per: ______________________

<PAGE>

                      EXHIBIT A TO SHAREHOLDERS' AGREEMENT

      This Exhibit A is a part of and is incorporated into that certain
Shareholders' Agreement (the "SHAREHOLDERS' AGREEMENT"), dated as of August 15,
2002, among Henry Birks & Sons Inc., a corporation amalgamated under the laws of
Canada (the "CORPORATION"), Henry Birks & Sons Holdings Inc., a corporation
incorporated under the laws of Canada ("HOLDINGS") and Prime Investments SA, a
Luxembourg corporation (together, with each transferee thereof of Common Shares
that agrees to be bound by the terms of the Shareholders' Agreement in
accordance with Section 8.5 thereof, the "INVESTORS.") Capitalized terms used in
this Exhibit A without definition herein shall have the meanings assigned to
them in the Shareholders' Agreement.

      1. Registration on Request.

            1.1 Request. Subject to the other provisions of this Section 1 and
the other provisions of this Exhibit A, at any time after (i) the Corporation's
initial Qualified Public Offering (ii) a transaction described in Section
6.1(b)(ii) or (iii) of the Shareholders Agreement with an issuer whose Shares
are listed on a US national securities exchange or a Canadian securities
exchange or quoted on the NASDAQ, NMS or Small Cap, or (iii) the conversion by
the Investor of its Shares as provided in Article III of the Shareholders'
Agreement, upon the written request of the Investor, requesting that the issuer
of the Registrable Securities (the "ISSUER") held by the Investor effect the
registration under the securities laws of the jurisdiction in which such
Issuer's Shares are registered or the qualification for sale in Canada (a
"QUALIFICATION") pursuant to a final prospectus (a "CANADIAN PROSPECTUS") filed
with, and in respect of which a receipt has been issued by, each of the
securities commissions or similar regulatory authority of each of the provinces
of Canada (the "CANADIAN COMMISSIONS"), of all or any part of such the
Investor's Registrable Securities (but not less than 250,000 Registrable
Securities), the Issuer will as soon as is practicable give written notice of
such requested registration or Qualification to all holders of Registrable
Securities, and thereupon will use its reasonable best efforts to effect, as
expeditiously as practicable, the registration or Qualification under the
applicable securities laws of Registrable Securities which the Issuer has been
so requested to register by the Investor. Notwithstanding the foregoing, the
Issuer shall not be required to effect a registration or Qualification pursuant
to this Section 1.1:

      (a) if the Issuer has already effected one (1) registration or
Qualification pursuant to this Section 1.1 at the request of Investor and such
registration or Qualification has been declared or ordered effective; or

      (b) within one hundred eighty (180) days after a merger, amalgamation or
other reorganization pursuant to which the Common Shares have been exchanged or
converted into common shares of Mayor's Jewelers Inc.

            1.2 Registration Statement Form. Registrations under this Section 1
shall be on such appropriate registration form and Qualifications shall be made
pursuant to such appropriate type of Canadian Prospectus, as permitted by
applicable securities

<PAGE>

laws and the rules and regulations thereunder and as selected by the Issuer and
as acceptable to the Investor. The Issuer agrees to include in any such
registration statement and Canadian Prospectus all information which the
Investor, upon advice of counsel, shall reasonably request. The Issuer may, if
permitted by applicable law, effect any registration requested under this
Section 1 by the filing of a short-form registration statement (such as a Form
S-3 if the registration statement is filed under the United States Securities
Act) unless the Investor (or, if such registration involves an underwritten
public offering of Registrable Securities, the managing underwriter of such
public offering) shall notify the Issuer in writing that, in the reasonable
judgment of such managing underwriter, the use of a more detailed form specified
in such notice is of material importance to the success of such public offering,
in which case such registration shall be effected on the form so specified.

            1.3 Effective Registration Statement. A registration or
Qualification requested pursuant to this Section 1 shall not be deemed to have
been effected (a) unless a registration statement with respect thereto has
become effective or a receipt for a Canadian Prospectus has been issued by each
of the Canadian Commissions, provided that a registration which does not become
effective after the Issuer has filed a registration statement with respect
thereto or a Canadian Prospectus which is not receipted by the Canadian
Commissions solely by reason of the refusal to proceed of the Investor (other
than a refusal to proceed based upon the advice of counsel relating to a matter
with respect to the Issuer or the withdrawal of a request for registration or
Qualification pursuant to Subsection 1.1) shall be deemed to have been effected
by the Issuer unless the Investor shall have elected to pay all Registration
Expenses (as defined in Section 6 below) in connection with such registration or
Qualification, (b) if the registration does not remain effective or the
Registrable Securities do not remain qualified for sale pursuant to a Canadian
Prospectus for a period of at least 180 days or, if earlier, until all the
Registrable Securities requested to be registered or qualified for sale in
connection therewith were sold, (c) if, after it has become effective, such
registration or, after the qualification for sale of the Registrable Securities
in Canada, is interfered with by any stop order, injunction or other order or
requirement of the Securities and Exchange Commission (the "COMMISSION"), if the
registration involves a public offering in the United States, any of the
Commissions or other governmental authority or court for any reason, or (d) if
the conditions to closing specified in the purchase agreement or underwriting
agreement entered into in connection with such registration or Qualification are
not satisfied and no such registration or Qualification occurs, other than by
reason of some act or omission by the Investor.

            1.4 Priority in Requested Registrations. If a requested registration
or Qualification pursuant to this Section 1 involves an underwritten offering,
and the managing underwriter shall advise the Issuer in writing that, in its
opinion, the number of securities requested to be included in such registration
or Qualification exceeds the number which can be sold in such offering within a
price range acceptable to the Investor (such writing to state the basis of such
opinion and the approximate number of shares of securities which may be included
in such offering without such effect), the Issuer will include in such
registration or qualification for sale in Canada, to the extent of the number of
securities which the Issuer is so advised can be sold in such offering, first,
any

                                      A-2
<PAGE>

and all securities proposed to be registered or qualified for sale in Canada by
the Issuer for its own account as part of such registration or qualification,
second, Registrable Securities requested by the Investor, and third all other
securities of the Issuer proposed to be included in such registration or
qualification for sale in Canada, in accordance with the priorities, if any,
then existing among the Issuer and the holders of such securities.

            1.5 Registration Expenses. In connection with one registration or
Qualification of Registrable Securities pursuant to this Section 1, the Issuer
shall pay all Registration Expenses and the Investor shall pay all underwriting
discounts and commissions applicable to its Registrable Securities and any fees
of separate counsel employed by the Investor.

      2. Incidental Registration.

            2.1 Right to Include Registrable Securities. If, following the
public offering of the securities of the Issuer (which in the case of the
Corporation shall be a Qualified Public Offering), the Issuer proposes to
register or qualify for sale any of its securities (which are the same type as
Registrable Securities then held by the Investor) under the US Securities Act or
the securities laws of any province or territory of Canada by registration on
any form or qualification for sale in Canada pursuant to any type of Canadian
prospectus, for public sale for its own account or the account of any other
shareholder, it will each such time give prompt written notice to the Investor
of its intention to do so and of the Investor's rights under this Section 2,
prior to the proposed registration or qualification for sale (such notice, a
"REGISTRATION NOTICE"). Upon the written request of the Investor made as
promptly as practicable and in any event within ten (10) days after the receipt
of any such Registration Notice (which request shall specify the Registrable
Securities intended to be disposed of by the Investor), the Issuer will file a
registration statement or a Canadian Prospectus with respect to, and use its
reasonable best efforts to make effective or obtain receipts therefor from each
of the Commissions, at the earliest possible date, the registration or
qualification for sale in Canada under the applicable securities laws of all
Registrable Securities which the Issuer has been so requested to register by the
Investor thereof; provided, however, that if, at any time after giving written
notice of its intention to register or qualify for sale in Canada any
Registrable Securities and prior to the effective date of the registration
statement filed in connection with such registration or date of issuance of
receipts for a Canadian Prospectus, the Issuer shall determine for any reason
not to register or to delay registration or qualification for sale of such
securities, the Issuer may, at its election, give written notice of such
determination to the Investor and (i) in the case of a determination not to
register or qualify for sale, the Issuer shall be relieved of its obligation to
register or qualify for sale in Canada any Registrable Securities in connection
with such registration or offering and (ii) in the case of a determination to
delay registering or qualifying for sale in Canada, the Issuer shall be
permitted to delay registering or qualifying for sale any Registrable
Securities, for the same period as the delay in registering or qualifying for
sale such other securities.

            2.2 Priority in Incidental Registrations. If the managing
underwriter of any underwritten offering shall advise the Issuer that the number
of Registrable Securities

                                      A-3
<PAGE>

requested to be included in such registration or qualification exceeds the
number which can be sold in such offering, and the Issuer has so advised the
Investor in writing, then the Issuer will include in such registration or
qualification, to the extent of the number of Registrable Securities which the
Issuer is so advised can be sold in (or during the time of) such offering,
first, any and all securities proposed to be registered or qualified for sale in
Canada by the Issuer for its own account as part of such registration, second,
the Registrable Securities requested to be included in such registration or
qualification by the Investor if exercising its rights under Section 2.1 hereof
and other holders of Registrable Securities, who have exercised demand
registration rights comparable to the Investor's rights under Section 2.1
hereof, pro rata among such holders on the basis of the number of Registrable
Securities requested to be registered or qualified by such holders and third,
all other securities of the Issuer proposed to be included in such registration,
in accordance with the priorities, if any, then existing among the Issuer and
the holders of such securities. In connection with any registration or

            3.3 Underwriters. The distribution for the account of the Investor
shall in any underwritten offering be underwritten by the same underwriters who
underwrite the distribution of Registrable Securities for the account of any
other holder of Registrable Securities exercising demand registration rights
comparable to those set forth in Section 2.1 hereof and the Issuer.

            3.4 Legal Opinions. The Investor shall retain counsel and shall
cause such counsel to deliver to the managing underwriter of any underwritten

reasonably require.

            3.5 Execution of Documents. The Investor shall, upon request of the

substance satisfactory to the managing underwriter of any underwritten offering.
The Investor shall execute an underwriting agreement in form and substance
satisfactory to such managing underwriter, which underwriting agreement shall
contain customary representations and warranties to be given by the Investor
(including representations regarding the material accuracy and completeness of
the information provided thereby pursuant to Subsection 3.1) and provisions
whereby the Issuer, on the one hand, and the Investor, on the other hand,
indemnify each other as provided in Section 6.

            3.6 Registration Statement. The Issuer will deliver to the Investor

any revised or supplemental prospectuses as the Investor may from time to time
request.

      5. INTENTIONALLY OMITTED.

      6. Indemnity.

      (a) The Issuer will indemnify and hold harmless the Investor if its
Registrable Securities were included in a registration statement or Canadian
Prospectuses prepared under Section 1 or Section 2 hereof, against all claims,
losses, damages, liabilities and expenses resulting from any untrue statement or
allegedly untrue statement of a material fact contained or incorporated by
reference in a prospectus or in any related registration statement or in any
Canadian preliminary or final Prospectus, notification or the like or from any
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances under
which they

                                      A-5
<PAGE>

were made, not misleading, except insofar as the same may have been based on
information furnished in writing to the Issuer by the Investor or such
underwriter expressly for use therein and used in accordance with such writing.
The Investor, by acceptance of the provisions herein, agrees to furnish to the
Issuer such information concerning the Investor and the proposed sale or
distribution as shall, in the opinion of counsel for the Issuer, be necessary in
connection with any such registration or Qualification of any Registrable
Securities owned by the Investor, and to indemnify and hold harmless the Issuer,
its officers and directors and each of its underwriters (and any person who
controls the Issuer or such underwriters within the meaning of Section 15 of the
US Securities Act) against all claims, losses, damages, liabilities and expenses
resulting from any untrue statement or allegedly untrue statement of a material
fact furnished in writing by the Investor to the Issuer or to any underwriter of
Registrable Securities sold by the Investor, expressly for use in connection
with such registration or Qualification and used in accordance with such writing
and from any omission therefrom or alleged omission therefrom of a material fact
needed to be furnished or necessary to make the statements therein, in light of
the circumstances under which they were made, not misleading.

      (b) Promptly after receipt by the Investor of written notice of the
commencement of any action or proceeding involving a claim referred to in
Section 6(a), the Investor will, if a claim in respect thereof is to be made
against the Issuer, give written notice to the latter of the commencement of
such action; provided, however, that the failure of the Investor to give notice
as provided herein shall not relieve the indemnifying party of its obligations
under the preceding subsections of this Section 6, except to the extent that the
Issuer is prejudiced by such failure to give notice. In case any such action
shall be brought against the Investor and it shall notify the Issuer of the
commencement thereof, the Issuer shall be entitled to participate therein and,
to the extent that it may wish, to assume the defense thereof, with counsel
reasonably satisfactory to the Investor and after written notice from the Issuer
to the Investor of its election so to assume the defense thereof, the Issuer
shall not be liable to the Investor for any legal or other expenses (including
fees and expenses of attorneys) subsequently incurred by the Investor in
connection with the defense thereof. Notwithstanding the foregoing, in any
action or proceeding in which both the Issuer and the Investor is, or is
reasonably likely to become, a party, the Investor shall have the right to
employ separate counsel at the Issuer's expense and to control its own defense
of such action or proceeding if, in the reasonable opinion of counsel to the
Investor, (a) there are or may be legal defenses available to the Investor or to
other indemnified parties that are different from or additional to those
available to the Issuer or (b) any conflict or potential conflict exists between
the Issuer and the Investor that would make such separate representation
advisable. The Issuer shall not be liable for any settlement of any action or
proceeding effected without its written consent, which consent shall not be
unreasonably withheld. The Issuer shall not, without the consent of the
Investor, which consent shall not be unreasonably withheld, 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 Investor
of a general release from all liability in respect to such claim or litigation
or which requires action by the Investor.
