                                    GUARANTEE

By: AEGON N.V. (the "Guarantor")

Whereas:

A.                As part of its CDN 500,000,000 commercial paper program (the
"Program") Transamerica Commercial Finance Corporation, Canada (the "Issuer")
proposes, from time to time, to issue Notes.

B.                The Notes will be issued pursuant to an issuing and paying
agency agreement made as of April 30, 1989 as amended by a letter agreement
dated October 1, 1998 between, the Issuer, Transamerica Finance Group, Inc. (nka
Transamerica Finance Corporation) and Canadian Imperial Bank of Commerce in its
capacity as agent (as the same may be replaced from time to time, the "Issuing
and Paying Agent") (as such agreement may be further amended, supplemented,
replaced or otherwise modified from time to time, the "Issuing and Paying Agency
Agreement").

C.                The Notes will be sold pursuant to one or more dealer
agreements entered into from time to time between the Issuer and the dealers
named therein including without limitation, the dealer agreement dated May 31,
1989 between the Issuer and the dealers named in it (collectively, as such
agreements may be amended, supplemented, replaced or otherwise modified from
time to time, the "Dealer Agreements").

D.                AEGON has agreed to guarantee unconditionally and irrevocably
all payments of principal, premium (if any) and interest (if any) due in respect
of the Notes issued during the term of this Guarantee as set forth above and
issued as part of the Program (the "Notes") by the Issuer pursuant to the
Issuing and Paying Agency Agreement.

Now this Guarantee witnesses and it is hereby declared as follows:

                   AEGON N.V., a corporation duly incorporated under the laws of
The Netherlands, hereby unconditionally and irrevocably guarantees to CDS & Co.,
as nominee of the Canadian Depository for Securities Limited, or to its
registered assigns (in such capacity together with its registered assigns,
"CDS") for the benefit of CDS and each holder (a "Holder") of a Note issued by
the Issuer, a wholly-owned subsidiary of the Guarantor, and evidenced by one or
more global notes deposited with CDS (the "Global Notes"), the prompt and
punctual payment (and not merely the collection) of all obligations represented
by the Global Notes, when and as the same shall become due and payable, without
any requirement that CDS, the Holder or the Issuing and Paying Agent first
proceed against the Issuer. All payments to be made under this Guarantee in
respect of the Global Notes shall be payable to CDS. This Guarantee shall also
cover all charges and expenses related to the Notes and all expenses incurred by
either CDS or the Holder in enforcing its rights under this Guarantee.

<PAGE>

                                       -2-

                  The liability of the Guarantor under this Guarantee shall be
unconditional and irrevocable for the duration of this Guarantee, as hereinafter
set forth, irrespective of (i) any lack of validity or enforceability of any
Global Note or any Note, (ii) any change of the time, manner or place or
payment, or any other term, of any Global Note or any Note, (iii) any law,
regulation or order of any jurisdiction affecting any term of any Global Note or
any Note or CDS's or any Holder's rights with respect thereto, and (iv) any
other circumstances which might otherwise constitute a defence available to, or
a discharge of, the Issuer or the Guarantor.

                   The Guarantee shall extend to all Notes issued by the Issuer
for the period from August 1, 2000 until June 30, 2003 (the "Duration"). The
Guarantee shall continue in full force and effect until all principal, premium
and interest (including any additional amounts required to be paid in accordance
with the Notes) and all other monies payable in respect of each Note issued by
the Issuer during the Duration of this Guarantee have been paid. The Guarantee
may be renewed, in Guarantor's sole discretion, for a specified duration in
order to continue to serve in full force and effect for Notes issued by the
Issuer after the Duration of this Guarantee. Renewal of the Guarantee will
require an amendment to this Guarantee to be issued by the Guarantor on or
before June 15, 2003. In the event that the Issuer is no longer an affiliated
company of Guarantor, this Guarantee shall automatically terminate and be of no
force or effect with respect to all Notes issued subsequent to such event. Any
such termination of this Guarantee shall not affect the rights of any holders of
Notes issued during the Duration while the Issuer was an affiliated company of
Guarantor.

                  This Guarantee is unsecured and unsubordinated and ranks pari
passu with all unsecured and unsubordinated indebtedness of the Guarantor other
than obligations that by mandatory operation of law would be given priority in a
dissolution of the Guarantor.

                    The Guarantor hereby waives (i) demand, notice and
presentment, promptness, diligence, notice of acceptance and all other notice,
marshalling of assets and set-off, together with any defence by reason of
extension of time for payment or other indulgence granted by the Issuing and
Paying Agent, CDS or any Holder, or any other defence or matter whatsoever which
would otherwise release the Guarantor, and (ii) any requirement that the Issuing
and Paying Agent, CDS or any Holder exhaust any right or take any action against
the Issuer or any collateral security before proceeding against the Guarantor.
The Guarantor will not exercise any rights which it may acquire by way of
subrogation or by any indemnity, reimbursement or other agreement until all
outstanding Notes and all of the obligations under this Guarantee shall have
been paid in full. The Guarantor agrees that, if at any time all or any part of
any payment under this Guarantee is or must be rescinded or returned by CDS, the
Holder or the Issuing and Paying Agent for any reason whatsoever (including,
without limitation, the insolvency, bankruptcy or reorganization of the Issuer
or the Guarantor), then such amount shall, for purposes of this Guarantee, to
the extent that such payment is or must be rescinded or returned, be deemed to
have continued to be outstanding, notwithstanding such payment hereunder to CDS,
the Holder or the Issuing and Paying Agent, as the case may be, and this
Guarantee shall continue to be effective or be reinstated, as the case may be,
as to such amount, all as though such application has not been made.

                                      -3-

                    Any payments to CDS or the Issuing and Paying Agent or to
any Holder (each Dealer and Holder is hereinafter referred to in this paragraph
as a "Payee") from time to time with respect to this Guarantee shall be in
Canadian dollars and shall be payable free and clear of and without deduction or
withholding for, or on account of, any and all present or future taxes, duties,
assessments, levies and other governmental charges of any nature whatsoever no
or hereafter imposed, levied, collected, withheld or assessed in The Netherlands
or in any other jurisdiction from which such payments are made or any territory
or political subdivision thereof, unless such deduction or withholding is
required by law ("Foreign Taxes"). If by operation of law or otherwise, Foreign
Taxes are required to be deducted or withheld from any amounts payable to a
Payee, the Guarantor agrees to pay such additional amounts to each Payee (the
"Additional Amounts") as may be necessary to ensure that the net amount actually
received by the Payee, after deduction of any Foreign Taxes imposed with respect
to the payment of such Additional Amounts, shall equal the amount the Payee
would have received if no Foreign Taxes had been deducted or withheld from such
payment; provided, however, that no Additional Amounts shall be so payable for
or on account of: (i) any Foreign Taxes which would not have been imposed but
for the fact that any Payee: (A) had a present or former personal or business
connection with The Netherlands or any other jurisdiction from which payments
are made, or any territory or political subdivision thereof (a "Foreign
Jurisdiction") other than the mere ownership of, or receipt of payment under,
the Notes; (B) presented such Notes for payment in any Foreign Jurisdiction
unless such Notes could not have been presented for payment elsewhere;
(C) presented a Note for payment more than fifteen (15) days after the date on
which such payment became due and payable or the date on which payment thereof
is duly provided for, whichever occurs later; or (D) did not provide to the
Issuer correct or sufficient information to avoid any withholding of taxes;
(ii) any estate, inheritance, gift, sale, transfer, personal property or similar
tax, assessment or other governmental charge; or (iii) any Foreign Taxes which
are payable otherwise than by withholding or deduction.

                    To the extent that the Guarantor or any of its respective
properties, assets or revenues may have or may hereafter become entitled to, or
have attributed to it, any right of immunity, on the grounds of sovereignty or
other similar grounds, from any legal action, suit or proceeding in connection
with or arising out of this Guarantee, from the giving of any relief hereunder,
from set-off or counterclaim, from the jurisdiction of any court, from service
of process, from attachment upon or prior to judgement, from attachment in aid
of execution of judgement, or from execution of judgement or other legal process
or proceeding for the giving of any relief or for the enforcement of any
judgement, in any jurisdiction in which any proceeding may at any time be
commenced, with respect to its obligations, liabilities or any other matter
under or arising out of or in connection with this Guarantee, the Guarantor
hereby irrevocably and unconditionally waives, and agrees for the benefit of CDS
and each Holder from time to time of a Note, not to plead or claim any such
immunity, and consents to such relief and enforcement.

                  This Guarantee shall be governed by and construed in
accordance with the laws of the State of New York without regard to conflicts of
law provisions, except with respect to authorization and execution by or on
behalf of the Guarantor which are required to be governed by the laws of The
Netherlands. The Guarantor agrees that any legal action suit or proceeding

<PAGE>

                                      - 4 -

against it arising out of or related to this Guarantee may be brought in the
United States federal courts located in the Borough of Manhattan or the courts
of the State of New York located in the Borough of Manhattan and hereby
irrevocably accepts and submits to the non-exclusive jurisdiction of the
aforementioned courts, in personam, generally and unconditionally, with respect
to any suit, action or proceeding in connection with or arising out of this
Guarantee for itself and its respective properties, assets and revenues. The
Guarantor agrees that a final unappealable judgement in any action or proceeding
arising out of or relating to this Guarantee shall be conclusive and may be
enforced in any other jurisdiction otherwise having jurisdiction over the
Guarantor by suit on the judgement or in any other manner provided by law.

                   The Guarantor, hereby consents to accept service of process
at the offices of LeBouef, Lamb, Greene & MacRae Attention Donald Henderson,
located at 125 West 55th Street, New York, New York 10019 and acknowledges that
process may be served in any suit or proceeding instituted in any Federal or
State court located in the Borough of Manhattan arising out of or relating to
this Guarantee, in accordance with legal procedures prescribed for such courts,
provided that in the case of such service of process upon the process agent, the
party effecting the service shall also deliver a copy thereof to Guarantor via
overnight courier service to the attention of Group Treasury at AEGON NV,
AEGONplein 50, 2591 TV, The Hague, The Netherlands. Nothing herein shall in any
way be deemed to limit the ability of CDS, the Issuing and Paying Agent or the
Holder to serve any such legal process, summons, notices and documents in any
other manner permitted by applicable law or to obtain jurisdiction over the
Guarantor or bring actions, suits or proceedings against the Guarantor in such
other jurisdictions, and in such manner, as may be permitted by applicable law.

securities laws as set forth herein or as otherwise required by such laws at the time a transfer is proposed.

of its employees is obligated under any contract (including licenses, covenants or commitments of any nature) or other agreement, or subject to any judgment, decree or order of any court or administrative agency, that would interfere with their
duties to the Company or that would conflict with the Company’s business as proposed to be conducted. Neither the execution nor delivery of this Agreement, nor the carrying on of the Company’s business by the employees of the Company, nor
the conduct of the Company’s business as proposed, will, to the Company’s knowledge, conflict with or result in a breach of the terms, conditions or provisions of, or constitute a default under, any contract, covenant or instrument under
which any employee is now obligated. The Company does not believe it is or will be necessary to utilize any inventions, trade secrets or proprietary information of any of its employees made prior to their employment by the Company, except for

experience in evaluating and investing in private placement transactions of securities in companies similar to the Company so that it is capable of evaluating the merits and risks of its investment in the Company and has the capacity to protect its

understands that other than pursuant to the terms of this Agreement, the Company has no present intention of registering the Securities or the Conversion Shares. Purchaser also understands that there is no assurance that any exemption from
registration under the Securities Act will be available and that, even if available, such exemption may not allow Purchaser to transfer all or any portion of the Securities or the Conversion Shares under the circumstances, in the amounts or at the
times Purchaser might propose. 
 
(b)    Acquisition for Own Account.    Purchaser is acquiring the Securities and the Conversion Shares for Purchaser’s own account for investment only, and not with a present
view towards their distribution other than in compliance with the Securities Act.

they are subsequently registered under the Securities Act or an exemption from such registration is available. Purchaser has been advised or is aware of the provisions of Rule 144 promulgated under the Securities Act as in effect from time to time,
which permits limited resale of shares purchased in a private placement subject to the satisfaction of certain conditions, including, among other things: the availability of certain current public information about the Company, the resale occurring
following the required holding period under Rule 144 and (other than Rule 144(k)) the number of shares being sold during any three-month period not exceeding specified limitations.

6.    REGISTRATION RIGHTS. 
 
6.1    Definitions.    As used in this Section 6, the following terms shall have the following respective meanings: 
 
“Form S-3” means such form under the Securities Act as in effect on the date hereof
or any successor registration form under the Securities Act subsequently adopted by the SEC which permits inclusion or incorporation of substantial information by reference to other documents filed by the Company with the SEC. 
 
“Holder” means any person owning of
record Registrable Securities that have not been sold to the public or any assignee of record of such Registrable Securities in accordance with Section 6.7 hereof. 
 
“Register,” “registered,” and “registration” refer
to a registration effected by preparing and filing a registration statement in compliance with the Securities Act, and the declaration or ordering of effectiveness of such registration statement or document. 
 
“Registrable Securities” means (a)
Common Stock of the Company issued or issuable upon conversion of the Shares; (b) Common Stock of the Company issued or issuable upon exercise of the Warrants; and (c) any Common Stock of the Company issued as (or issuable upon the conversion or

shall not include (i) any securities held by a registered broker-dealer, or any securities held by an affiliate or associate of a broker-dealer who (x) did not purchase the securities in the ordinary course of business or personal affairs or (y) at
the time of purchase of the securities, had an agreement or understanding, directly or indirectly, with any person to distribute such securities, and (ii) any 
 

13 

securities sold by a person to the public either pursuant to a registration statement or Rule 144 or sold
in a private transaction in which the transferor’s rights under this Section 6 are not assigned. 
 
“Registrable Securities then outstanding” shall be the number of shares determined by calculating the total number

“Selling Expenses” shall mean all underwriting discounts and selling commissions applicable to the sale. 
 
6.2    Mandatory Registration.    The Company shall prepare
and file with the SEC on or before May 31, 2003 (the “SEC Filing Date”) a Registration Statement on Form S-3 or, if Form S-3 is not available, on another appropriate form reasonably acceptable to the Purchasers, which covers the resale of
a number of shares of Common Stock equal to at least the number of Registrable Securities issuable to each Holder upon conversion of the Shares and exercise of the Warrants, determined as if the Shares were converted in full (based on a $3.25 per
share conversion price) and the Warrants were exercised in full. If at any time the number of shares of Common Stock included in the Registration Statement required to be filed as provided in the first sentence of this Section 6.2(a) shall be
insufficient to cover the number of shares of Common Stock issuable on conversion in full of the unconverted Shares and unexercised Warrants, then promptly, but in no event later than 60 days after such insufficiency shall occur, the Company shall
file with the SEC an additional Registration Statement on Form S-3, or another appropriate form (which shall not constitute a post-effective amendment to the Registration Statement filed pursuant to the first sentence of this Section 6.2(a))
covering such number of shares of Common Stock as shall be sufficient to permit such conversion and exercise. For all purposes of this Agreement such additional Registration Statement shall be deemed to be the Registration Statement required to be
filed by the Company pursuant to this Section 6.2(a), and the Company and the Holders shall have the same rights and obligations with respect to such additional Registration Statement as they shall have with respect to the initial Registration

the number of shares so registered. 
 

14 

 
6.4    Obligations of the Company.    Whenever required to effect the registration of any Registrable Securities, the Company shall: 
 
(a)    Prepare and
file with the SEC a Registration Statement on Form S-3 with respect to the number of Registrable Securities provided in Section 6.2(a), and thereafter to use all reasonable efforts to cause each Registration Statement relating to Registrable
Securities to become effective and keep the Registration Statement effective for two years after the Closing Date. 
 
(b)    Prepare and file with the SEC such amendments and supplements to such registration
statement and the prospectus used in connection with such registration statement as may be necessary to comply with the provisions of the Securities Act with respect to the disposition of all securities covered by such registration statement for the
period set forth in paragraph (a) above. 
 
(c)    Furnish to the Holders such number of copies of a prospectus, including a preliminary prospectus, in conformity with the requirements of the Securities Act, and such other documents as they may
reasonably request in order to facilitate the disposition of Registrable Securities owned by them. 
 
(d)    Use its reasonable best efforts to register and qualify the securities covered by such
registration statement under such other securities or Blue Sky laws of such jurisdictions as shall be reasonably requested by the Holders; provided that the Company shall not be required in connection therewith or as a condition thereto to
qualify to do business or to file a general consent to service of process in any such states or jurisdictions. 
 
(e)    Notify each Holder of Registrable Securities covered by such registration statement at
any time when a prospectus relating thereto is required to be delivered under the Securities Act of the happening of any event as a result of which the prospectus included in such registration statement, as then in effect, includes an untrue
statement of a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, and use its best efforts to prepare a supplement
or amendment to the Registration Statement to correct such untrue statement or omission, and deliver such number of copies of such supplement or amendment to each Holder as such Holder may reasonably request. 
 
(f)    Use all
reasonable efforts to prevent the issuance of stop orders or any other suspensions in trading of the Company’s Common Stock by the SEC or any applicable exchange or market, and use its best efforts to have removed or reversed any such stop
order or suspension in trading that occurs. 
 
6.5    Obligations of Holder. 
 
(a)    No Holder shall have any right to obtain or seek an injunction restraining or otherwise delaying any such registration as the result of any controversy that might
arise with respect to the interpretation or implementation of this Section 6. 
 

15 

 
(b)    It shall be a condition precedent to the obligations of the Company to take any action pursuant to Section 6.2 or 6.4 that each Holder shall furnish to the Company such information regarding itself,
the Registrable Securities held by it and the intended method of disposition of the Registrable Securities held by it as shall be reasonably required to effect the registration of such Registrable Securities and shall execute such documents in
connection with such registration as the Company may reasonably request. 
 
(c)    Each Holder by such Holder’s acceptance of the Registrable Securities agrees to cooperate with the Company as reasonably requested by the Company in connection
with the preparation and filing of the Registration Statement hereunder, unless such Holder has notified the Company in writing of such Holder’s election to waive all of such Holder’s rights to register any securities under this Section 6;

 
(d)    Each Holder agrees that, upon receipt of any notice from the Company of the happening of any event of the kind described in Section 6.4(e), such Holder will immediately discontinue disposition of
Registrable Securities pursuant to the Registration Statement covering such Registrable Securities and all other transactions involving or relating to the Company’s securities until such Holder’s receipt of copies of a supplemented or
amended prospectus and, if so directed by the Company, such Holder shall deliver to the Company (at the expense of the Company) or destroy (and deliver to the Company a certificate of destruction) all copies in such Holder’s possession, of the
prospectus covering such Registrable Securities current at the time of receipt of such notice. 
 
6.6    Indemnification.    In the event any Registrable Securities are included in a registration statement under this Section 6: 
 
(a)    To the
extent permitted by law, the Company will indemnify and hold harmless each Holder, any partner, officer or director of each Holder, any underwriter (as defined in the Securities Act) for such Holder and each person, if any, who controls such Holder
or underwriter within the meaning of the Securities Act or the Exchange Act, against any losses, claims, damages, or liabilities (joint or several) to which they may become subject under the Securities Act, the Exchange Act or other federal or state
law, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any of the following statements, omissions or violations (collectively a “Violation”) by the Company: (i) any untrue
statement or alleged untrue statement of a material fact contained in such registration statement, including any preliminary prospectus or final prospectus contained therein or any amendments or supplements thereto, (ii) the omission or alleged
omission to state therein a material fact required to be stated therein, or necessary to make the statements therein not misleading, or (iii) any violation or alleged violation by the Company of the Securities Act, the Exchange Act, any state
securities law or any rule or regulation promulgated under the Securities Act, the Exchange Act or any state securities law in connection with the offering covered by such registration statement; and the Company will pay as incurred to each such
Holder, partner, officer, director, underwriter or controlling person for any legal or other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, damage, liability or action; provided
however, that the indemnity agreement contained in this Section 6.6 shall not apply to amounts paid in settlement of any such loss, claim, damage, 
 

16 

 
liability or
action if such settlement is effected without the consent of the Company, which consent shall not be unreasonably withheld, nor shall the Company be liable in any such case for any such loss, claim, damage, liability or action to the extent that it
arises out of or is based upon a Violation which occurs in reliance upon and in conformity with written information furnished expressly for use in connection with such registration by such Holder, partner, officer, director, underwriter or
controlling person of such Holder. 
 
(b)    To the extent permitted by law, each Holder will, if Registrable Securities held by such Holder are included in the securities as to which such registration qualifications or compliance is being
effected, indemnify and hold harmless the Company, each of its directors, its officers and each person, if any, who controls the Company within the meaning of the Securities Act, any underwriter and any other Holder selling securities under such
registration statement or any of such other Holder’s partners, directors or officers or any person who controls such Holder, against any losses, claims, damages or liabilities (joint or several) to which the Company or any such director,
officer, controlling person, underwriter or other such Holder, or partner, director, officer or controlling person of such other Holder may become subject under the Securities Act, the Exchange Act or other federal or state law, insofar as such
losses, claims, damages or liabilities (or actions in respect thereto) arise out of or are based upon any Violation, in each case to the extent (and only to the extent) that such Violation occurs in reliance upon and in conformity with written
information furnished by such Holder under an instrument duly executed by such Holder and stated to be specifically for use in connection with such registration; and each such Holder will pay as incurred any legal or other expenses reasonably
incurred by the Company or any such director, officer, controlling person, underwriter or other Holder, or partner, officer, director or controlling person of such other Holder in connection with investigating or defending any such loss, claim,
damage, liability or action if it is judicially determined that there was such a Violation; provided, however, that the indemnity agreement contained in this Section 6.6 shall not apply to amounts paid in settlement of any such loss, claim,
damage, liability or action if such settlement is effected without the consent of the Holder, which consent shall not be unreasonably withheld; provided further, that in no event shall any indemnity under this Section 6.6 exceed the proceeds
from the offering received by such Holder. 
 
(c)    Promptly after receipt by an indemnified party under this Section 6.6 of notice of the commencement of any action (including any governmental action), such indemnified party will, if a claim in
respect thereof is to be made against any indemnifying party under this Section 6.6, deliver to the indemnifying party a written notice of the commencement thereof and the indemnifying party shall have the right to participate in, and, to the extent
the indemnifying party so desires, jointly with any other indemnifying party similarly noticed, to assume the defense thereof with counsel mutually satisfactory to the parties; provided, however, that an indemnified party shall have the right
to retain its own counsel, with the fees and expenses to be paid by the indemnifying party, if representation of such indemnified party by the counsel retained by the indemnifying party would be inappropriate due to actual or potential differing
interests between such indemnified party and any other party represented by such counsel in such proceeding. The failure to deliver written notice to the indemnifying party within a reasonable time of the commencement of any such action, if
materially prejudicial to its ability to defend such action, shall relieve such indemnifying party of any liability to the indemnified 
 

17 

 
party under
this Section 6.6, but the omission so to deliver written notice to the indemnifying party will not relieve it of any liability that it may have to any indemnified party otherwise than under this Section 6.6. 
 
(d)    If the
indemnification provided for in this Section 6.6 is held by a court of competent jurisdiction to be unavailable to an indemnified party with respect to any losses, claims, damages or liabilities referred to herein, the indemnifying party, in lieu of
indemnifying such indemnified party thereunder, shall to the extent permitted by applicable law contribute to the amount paid or payable by such 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 indemnifying party on the one hand and of the indemnified party on the other in connection with the Violation(s) that resulted in such loss, claim, damage or liability, as well as any other relevant
equitable considerations. The relative fault of the indemnifying party and of the indemnified party shall be determined by a court of law by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the indemnifying party or by the indemnified party and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or
omission; provided, that in no event shall any contribution by a Holder hereunder exceed the proceeds from the offering received by such Holder. 
 
(e)    The obligations of the Company and Holders under this Section 6.6 shall survive
completion of any offering of Registrable Securities in a registration statement and the termination of this agreement. No indemnifying party, in the defense of any such claim or litigation, shall, except with the consent of each indemnified party,
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 to such claim or
litigation.  
 
6.7    Assignment of Registration Rights.    The rights to cause the Company to register Registrable Securities pursuant to this Section 6 may be assigned by a Holder to a transferee or
assignee of Registrable Securities which (a) is a subsidiary, parent, general partner, limited partner, retired partner, member or retired member of a Holder, (b) is a Holder’s family member or trust for the benefit of an individual Holder, or
(c) acquires at least fifty thousand (50,000) shares of Registrable Securities (as adjusted for stock splits and combinations); provided, however, (i) the transferor shall, within ten (10) days after such transfer, furnish to the Company written
notice of the name and address of such transferee or assignee and the securities with respect to which such registration rights are being assigned and (ii) such transferee shall agree to be subject to all restrictions set forth in this Agreement.
