         MEETING

         (a)      In connection with each Amdocs Meeting and Amdocs Consent, the
                  Trustee shall exercise, either in person or by proxy, in
                  accordance with the instructions received from a Holder
                  pursuant to Section 4.3 hereof, the Holder Votes as to which
                  such Holder is entitled to direct the vote (or any lesser
                  number thereof as may be set forth in the instructions);
                  provided, however, that such written instructions are


                                       10
<PAGE>   11
                  received by the Trustee from the Holder prior to the time and
                  date fixed by it for receipt of such instructions in the
                  notice given by the Trustee to the Holder pursuant to Section
                  4.3 hereof.

         (b)      The Trustee shall cause such representatives as are empowered
                  by it to sign and deliver, on behalf of the Trustee, proxies
                  for Voting Rights to attend each Amdocs Meeting. Upon
                  submission by a Holder (or its designee) of identification
                  satisfactory to the Trustee's representatives, and at the
                  Holder's request, such representatives shall sign and deliver
                  to such Holder (or its designee) a proxy to exercise
                  personally the Holder Votes as to which such Holder is
                  otherwise entitled hereunder to direct the vote, if such
                  Holder either (i) has not previously given the Trustee
                  instructions pursuant to Section 4.3 hereof in respect of such
                  meeting, or (ii) submits to the Trustee's representatives
                  written revocation of any such previous instructions. At such
                  meeting, the Holder exercising such Holder Votes shall have
                  the same rights as the Trustee to speak at the meeting in
                  respect of any matter, question or proposition, to vote by way
                  of ballot at the meeting in respect of any matter, question or
                  proposition and to vote at such meeting by way of a show of
                  hands in respect of any matter, question or proposition.

4.9      DISTRIBUTION OF WRITTEN MATERIALS

                  Any written materials distributed by the Trustee to the
Holders pursuant to this Agreement shall be delivered or sent by mail (or
otherwise communicated in the same manner as Amdocs utilizes in communications
to holders of Amdocs Ordinary Shares) to each Holder at its address as shown on
the books of the Company. The Company shall provide or cause to be provided to
the Trustee for this purpose, on a timely basis and without charge or other
expense:

         (a)      a current List; and

         (b)      upon the request of the Trustee, mailing labels to enable the
                  Trustee to carry out its duties under this Agreement.

4.10     TERMINATION OF VOTING RIGHTS

                  The rights of a Holder with respect to the Holder Votes
exercisable in respect of the Exchangeable Shares held by such Holder, including
the right to instruct the Trustee as to the voting of or to vote personally such
Holder Votes, shall be deemed to be surrendered by the Holder to Amdocs or
Holdco, as the case may be, and such Holder Votes and the Voting Rights
represented thereby shall cease immediately upon the delivery by such holder to
the Trustee of the certificates representing such Exchangeable Shares in
connection with the exercise by the Holder of the Exchange Right or the
occurrence of the automatic exchange of Exchangeable Shares for Amdocs Ordinary
Shares, as specified in Article 5 hereof (unless, in either case,


                                       11
<PAGE>   12
Holdco shall not have delivered the requisite Amdocs Ordinary Shares issuable in
exchange therefor to the Trustee for delivery to the Holders), or upon the
retraction or redemption of Exchangeable Shares pursuant to Article 6 or Article
7 of the Exchangeable Share Provisions, or upon the effective date of the
liquidation, dissolution or winding-up of the Company pursuant to Article 5 of
the Exchangeable Share Provisions, or upon the purchase of Exchangeable Shares
from the holder thereof by Holdco (or Amdocs or Parentco) pursuant to the
exercise by such person of the Retraction Call Right, the Redemption Call Right
or the Liquidation Call Right.

                                    ARTICLE 5
                      EXCHANGE RIGHT AND AUTOMATIC EXCHANGE

5.1      GRANT AND OWNERSHIP OF THE EXCHANGE RIGHT

                  Holdco hereby grants to the Trustee as trustee for and on
behalf of, and for the use and benefit of, the Holders (a) the right (the
"Exchange Right"), upon the occurrence and during the continuance of an
Insolvency Event, to require Holdco to purchase from each or any Holder all or
any part of the Exchangeable Shares held by the Holder and (b) the Automatic
Exchange Rights, all in accordance with the provisions of this Agreement. Holdco
hereby acknowledges receipt from the Trustee as trustee for and on behalf of the
Holders of good and valuable consideration (and the adequacy thereof) for the
grant of the Exchange Right and the Automatic Exchange Rights by Holdco to the
Trustee. During the term of the Trust and subject to the terms and conditions of
this Agreement, the Trustee shall possess and be vested with full legal
ownership of the Exchange Right and the Automatic Exchange Rights and shall be
entitled to exercise all of the rights and powers of an owner with respect to
the Exchange Right and the Automatic Exchange Rights, provided that the Trustee
shall:

         (a)      hold the Exchange Right and the Automatic Exchange Rights and
                  the legal title thereto as trustee solely for the use and
                  benefit of the Holders in accordance with the provisions of
                  this Agreement; and

         (b)      except as specifically authorized by this Agreement, have no
                  power or authority to exercise or otherwise deal in or with
                  the Exchange Right or the Automatic Exchange Rights, and the
                  Trustee shall not exercise any such rights for any purpose
                  other than the purposes for which this Trust is created
                  pursuant to this Agreement.

5.2      LEGENDED SHARE CERTIFICATES

                  The Company will cause each certificate representing
Exchangeable Shares to bear an appropriate legend notifying the Holders of:


                                       12
<PAGE>   13
         (a)      their right to instruct the Trustee with respect to the
                  exercise of the Exchange Right in respect of the Exchangeable
                  Shares held by a Holder; and

         (b)      the Automatic Exchange Rights.

5.3      GENERAL EXERCISE OF EXCHANGE RIGHTS

                  The Exchange Right shall be and remain vested in and exercised
by the Trustee. Subject to Section 7.15 hereof, the Trustee shall exercise the
Exchange Right only on the basis of instructions received pursuant to this
Article 5 from Holders entitled to instruct the Trustee as to the exercise
thereof. To the extent that no instructions are received from a Holder with
respect to the Exchange Right, the Trustee shall not exercise or permit the
exercise of the Exchange Right.

5.4      PURCHASE PRICE

                  The purchase price payable by Holdco for each Exchangeable
Share to be purchased by Holdco under the Exchange Right shall be an amount per
share equal to (a) the Current Market Price of an Amdocs Ordinary Share on the
last Business Day prior to the day of closing of the purchase and sale of such
Exchangeable Share under the Exchange Right plus (b) an additional amount
equivalent to the full amount of all dividends declared and unpaid on each such
Exchangeable Share (provided that if the record date for any such declared and
unpaid dividends occurs on or after the day of closing of such purchase and sale
the purchase price shall not include such additional amount equivalent to the
declared and unpaid dividends). In connection with each exercise of the Exchange
Right, Holdco will provide to the Trustee an Officer's Certificate setting forth
the calculation of the purchase price for each Exchangeable Share. The purchase
price for each such Exchangeable Share so purchased may be satisfied only by
Amdocs issuing and delivering or causing to be delivered to the Trustee, on
behalf of the relevant Holder, one Amdocs Ordinary Share and a check for the
balance, if any, of the purchase price without interest (but less any amounts
withheld pursuant to Section 5.13).

5.5      EXERCISE INSTRUCTIONS

                  Subject to the terms and conditions herein set forth, a Holder
shall be entitled, upon the occurrence and during the continuance of an
Insolvency Event, to instruct the Trustee to exercise the Exchange Right with
respect to all or any part of the Exchangeable Shares registered in the name of
such Holder on the books of the Company. To cause the exercise of the Exchange
Right by the Trustee, the Holder shall deliver to the Trustee, in person or by
mail, at its principal office in Toronto, Ontario or at such other places in
Canada as the Trustee may from time to time designate by written notice to the
Holders, the certificates representing the Exchangeable Shares which such Holder
desires Holdco to purchase, duly endorsed in blank, and accompanied by such
other documents and instruments as may be required to effect a transfer of
Exchangeable Shares under the NBBCA and the by-laws of the Company and such
additional documents and


                                       13
<PAGE>   14
instruments as the Trustee may reasonably require together with (a) a duly
completed form of notice of exercise of the Exchange Right, contained on the
reverse of or attached to the Exchangeable Share certificates, stating (i) that
the Holder thereby instructs the Trustee to exercise the Exchange Right so as to
require Holdco to purchase from the Holder the number of Exchangeable Shares
specified therein, (ii) that such Holder has good title to and owns all such
Exchangeable Shares to be acquired by Holdco free and clear of all liens, claims
and encumbrances, (iii) the names in which the certificates representing Amdocs
Ordinary Shares issuable in connection with the exercise of the Exchange Right
are to be issued and (iv) the names and addresses of the persons to whom such
new certificates should be delivered and (b) payment (or evidence satisfactory
to the Trustee, the Company, Amdocs and Holdco of payment) of the taxes (if any)
payable as contemplated by Section 5.8 of this Agreement. If only a part of the
Exchangeable Shares represented by any certificate or certificates delivered to
the Trustee are to be purchased by Holdco under the Exchange Right, a new
certificate for the balance of such Exchangeable Shares shall be issued by
Amdocs to the holder at the expense of the Company.

5.6      DELIVERY OF AMDOCS ORDINARY SHARES; EFFECT OF EXERCISE

                  Promptly after receipt of the certificates representing the
Exchangeable Shares which the Holder desires Holdco to purchase under the
Exchange Right (together with such documents and instruments of transfer and a
duly completed form of notice of exercise of the Exchange Right (and payment of
taxes, if any, payable as contemplated in Section 5.8 hereof or evidence
thereof)), duly endorsed in blank, the Trustee shall notify Holdco, Amdocs and
the Company of its receipt of the same, which notice to Holdco, Amdocs and the
Company shall constitute exercise of the Exchange Right by the Trustee on behalf
of the holder of such Exchangeable Shares, and Holdco shall immediately
thereafter deliver or cause to be delivered to the Trustee, for delivery to the
Holder of such Exchangeable Shares (or to such other persons, if any, properly
designated by such Holder), the certificates for the number of Amdocs Ordinary
Shares issuable in connection with the exercise of the Exchange Right, which
shares shall be duly issued and fully paid and non-assessable and shall be free
and clear of any lien, claim or encumbrance, and checks for the balance, if any,
of the total purchase price therefor without interest, but less any amounts
withheld pursuant to Section 5.13 hereof; provided, however, that no such
delivery shall be made unless and until the Holder requesting the same shall
have paid (or provided evidence satisfactory to the Trustee, the Company, Amdocs
and Holdco of the payment of) the taxes (if any) payable as contemplated by
Section 5.8 of this Agreement. Immediately upon the giving of notice by the
Trustee to Holdco, Amdocs and the Company of the exercise of the Exchange Right,
as provided in this Section 5.6, the closing of the transaction of purchase and
sale contemplated by the Exchange Right shall be deemed to have occurred, and
the Holder of such Exchangeable Shares shall be deemed to have transferred to
Holdco all of its right, title and interest in and to such Exchangeable Shares
and in the related interest in the Trust Estate and shall cease to be a holder
of such Exchangeable Shares and shall not be entitled to exercise any of the
rights of a holder in respect thereof, other than the right to receive his


                                       14
<PAGE>   15
proportionate part of the total purchase price therefor, unless the requisite
number of Amdocs Ordinary Shares (together with a check for the balance, if any,
of the total purchase price therefor without interest) is not allotted and
delivered by Holdco to the Trustee, for delivery to such Holder (or to such
other persons, if any, properly designated by such Holder), within five Business
Days of the date of the giving of such notice by the Trustee, in which case the
rights of the Holder shall remain unaffected until such Amdocs Ordinary Shares
are so allotted and delivered by Holdco and any such check is so delivered and
paid. Upon delivery by Holdco to the Trustee of such Amdocs Ordinary Shares, the
Trustee shall deliver such Amdocs Ordinary Shares to such Holder (or to such
other persons, if any, properly designated by such Holder). Concurrently with
such Holder ceasing to be a holder of Exchangeable Shares, the Holder shall be
considered and deemed for all purposes to be the holder of the Amdocs Ordinary
Shares delivered to it pursuant to the Exchange Right.

5.7      EXERCISE OF EXCHANGE RIGHT SUBSEQUENT TO RETRACTION

                  In the event that a Holder has exercised its right under
Article 6 of the Exchangeable Share Provisions to require the Company to redeem
any or all of the Exchangeable Shares held by the Holder (the "Retracted
Shares") and is notified by the Company pursuant to Section 6.7 of the
Exchangeable Share Provisions that the Company will not be permitted as a result
of solvency requirements of applicable law to redeem all such Retracted Shares,
provided that Holdco shall not have exercised the Retraction Call Right with
respect to the Retracted Shares and that the Holder has not revoked the
retraction request delivered by the Holder to the Company pursuant to Section
6.1 of the Exchangeable Share Provisions, the retraction request will constitute
and will be deemed to constitute notice from the Holder to the Trustee
instructing the Trustee to exercise the Exchange Right with respect to those
Retracted Shares which the Company is unable to redeem. In any such event, the
Company hereby agrees with the Trustee and in favor of the Holder immediately to
notify the Trustee of such prohibition against the Company redeeming all of the
Retracted Shares and immediately to forward or cause to be forwarded to the
Trustee all relevant materials delivered by the Holder to the Company or to the
transfer agent of the Exchangeable Shares (including without limitation a copy
of the retraction request delivered pursuant to Section 6.1 of the Exchangeable
Share Provisions) in connection with such proposed redemption of the Retracted
Shares and the Trustee will thereupon exercise the Exchange Right with respect
to the Retracted Shares that the Company is not permitted to redeem and will
require Holdco to purchase such shares in accordance with the provisions of this
Article 5.

5.8      STAMP OR OTHER TRANSFER TAXES

                  Upon any sale of Exchangeable Shares to Holdco pursuant to the
Exchange Right or the Automatic Exchange Rights, the share certificate or
certificates representing Amdocs Ordinary Shares to be delivered in connection
with the payment of the total purchase price therefor shall be issued in the
name of the Holder of the Exchangeable Shares so sold or in such


                                       15
<PAGE>   16
names as such Holder may otherwise direct in writing without charge to the
holder of the Exchangeable Shares so sold, provided, however, that such Holder
(a) shall pay (and neither Holdco, Amdocs, the Company nor the Trustee shall be
required to pay) any documentary, stamp, transfer or other similar taxes that
may be payable in respect of any transfer involved in the issuance or delivery
of such shares to a person other than such Holder or (b) shall have established
to the satisfaction of the Trustee, Amdocs, Holdco and the Company that such
taxes, if any, have been paid.

5.9      NOTICE OF INSOLVENCY EVENT

                  Immediately upon the occurrence of an Insolvency Event or any
event which with the giving of notice or the passage of time or both would be an
Insolvency Event, the Company and Amdocs shall give written notice thereof to
the Trustee. As soon as practicable after receiving notice from the Company and
Amdocs or from any other person of the occurrence of an Insolvency Event, the
Trustee will mail to each Holder, at the expense of Amdocs, a notice of such
Insolvency Event in the form provided by Amdocs, which notice shall contain a
brief statement of the right of the Holders with respect to the Exchange Right.

5.10     QUALIFICATION OF AMDOCS ORDINARY SHARES

                  Amdocs covenants that if any Amdocs Ordinary Shares to be
issued and delivered pursuant to the Exchange Right or the Automatic Exchange
Rights require registration or qualification with or approval of or the filing
of any document including any prospectus or similar document or the taking of
any proceeding with or the obtaining of any order, ruling or consent from any
governmental or regulatory authority under any Canadian or United States
federal, provincial or state law or regulation or pursuant to the rules and
regulations of any regulatory authority or the fulfillment of any other Canadian
or United States federal, provincial or state legal requirement (collectively,
the "Applicable Laws") before such shares may be delivered by Holdco to the
initial Holder thereof, Amdocs will in good faith expeditiously take all such
actions and do all such things as are necessary or desirable to cause such
shares of Amdocs Ordinary Shares to be and remain duly registered, qualified or
approved. Amdocs will in good faith expeditiously take all such actions and do
all such things as are reasonably necessary or desirable, pursuant to the terms
of the Combination Agreement to cause all shares of Amdocs Ordinary Shares to be
delivered pursuant to the Exchange Right or the Automatic Exchange Rights to be
listed, quoted or posted for trading on all stock exchanges and quotation
systems on which such shares have been listed by Amdocs and remain listed,
quoted or posted for trading at such time.

5.11     RESERVATION OF AMDOCS ORDINARY SHARES

                  Amdocs hereby represents, warrants and covenants for the
benefit of the holders of the Exchangeable Shares that it has irrevocably
reserved for issuance and will at all times keep


                                       16
<PAGE>   17
available, free from pre-emptive and other rights, out of its authorized and
unissued capital stock such number of Amdocs Ordinary Shares (a) as is equal to
the sum of (i) the number of Exchangeable Shares issued and outstanding from
time to time and (ii) the number of Exchangeable Shares issuable upon the
exercise of all rights to acquire Exchangeable Shares outstanding from time to
time and (b) as are now and may hereafter be required to enable and permit the
Company and Holdco to meet their respective obligations hereunder, under the
Support Agreement, under the Exchangeable Share Provisions and under any other
security or commitment pursuant to which Amdocs or Holdco may now or hereafter
be required to issue or deliver Amdocs Ordinary Shares to Holders.

5.12     AUTOMATIC EXCHANGE ON LIQUIDATION OF PARENT

         (a)      Amdocs will give the Trustee written notice of each of the
                  following events at the time set forth below:

                  (i)      in the event of any determination by the Board of
                           Directors of Amdocs to institute voluntary
                           liquidation, dissolution or winding-up proceedings
                           with respect to Amdocs or to effect any other
                           distribution of assets of Amdocs among its
                           shareholders for the purpose of winding up its
                           affairs, at least 60 days prior to the proposed
                           effective date of such liquidation, dissolution,
                           winding-up or other distribution; and

                  (ii)     as soon as practicable following the earlier of (A)
                           receipt by Amdocs of notice of, and (B) Amdocs
                           otherwise becoming aware of any threatened or
                           instituted claim, suit, petition or other proceedings
                           with respect to the involuntary liquidation,
                           dissolution or winding up of Amdocs or to effect any
                           other distribution of assets of Amdocs among its
                           shareholders for the purpose of winding up its
                           affairs, in each case where Amdocs has failed to
                           contest in good faith any such proceeding within 30
                           days of becoming aware thereof.

         (b)      As soon as practicable following receipt by the Trustee from
                  Amdocs of notice of any event (a "Liquidation Event")
                  contemplated by Section 5.12(a)(i) or 5.12(a)(ii) above, the
                  Trustee will give notice thereof to the Holders. Such notice
                  shall include a brief description of the automatic exchange of
                  Exchangeable Shares for Amdocs Ordinary Shares provided for in
                  Section 5.12(c) below.

         (c)      In order that the Holders will be able to participate on a pro
                  rata basis with the holders of Amdocs Ordinary Shares in the
                  distribution of assets of Amdocs in connection with a
                  Liquidation Event, on the fifth Business Day prior to the
                  effective date (the "Liquidation Event Effective Date") of a
                  Liquidation Event all of the then outstanding Exchangeable
                  Shares shall be automatically exchanged for


                                       17
<PAGE>   18
                  Amdocs Ordinary Shares. To effect such automatic exchange,
                  Holdco shall purchase each Exchangeable Share outstanding on
                  the fifth Business Day prior to the Liquidation Event
                  Effective Date and held by Holders, and each Holder shall sell
                  the Exchangeable Shares held by it at such time, for a
                  purchase price per share equal to (a) the Current Market Price
                  of an Amdocs Ordinary Share on the fifth Business Day prior to
                  the Liquidation Event Effective Date, which shall be satisfied
                  in full by Holdco issuing to the Holder one Amdocs Ordinary
                  Share, plus (b) to the extent not paid by the Company, an
                  additional amount equivalent to the full amount of all
                  dividends declared and unpaid on each such Exchangeable Share
                  and all dividends declared on Amdocs Ordinary Shares that have
                  not been declared on such Exchangeable Shares in accordance
                  with Section 3.1 of the Exchangeable Share Provisions
                  (provided that if the record date for any such declared and
                  unpaid dividends occurs on or after the day of closing of such
                  purchase and sale, the purchase price shall not include such
                  additional amounts equivalent to such declared and unpaid
                  dividends). In connection with such automatic exchange,
                  Holdco will provide to the Trustee an Officer's Certificate
                  setting forth the calculation of the purchase price for each
                  Exchangeable Share.

         (d)      On the fifth Business Day prior to the Liquidation Event
                  Effective Date, the closing of the transaction of purchase and
                  sale contemplated by the automatic exchange of Exchangeable
                  Shares for Amdocs Ordinary Shares shall be deemed to have
                  occurred, and each Holder of Exchangeable Shares shall be
                  deemed to have transferred to Holdco all of the Holder's
                  right, title and interest in and to such Exchangeable Shares
                  and the related interest in the Trust Estate and shall cease
                  to be a holder of such Exchangeable Shares and Holdco shall
                  deliver to the Holder the Amdocs Ordinary Shares issuable upon
                  the automatic exchange of Exchangeable Shares for Amdocs
                  Ordinary Shares and on the applicable payment date shall
                  deliver to the Trustee for delivery to the Holder a check for
                  the balance, if any, of the total purchase price for such
                  Exchangeable Shares without interest, but less any amounts
                  withheld pursuant to Section 5.13 hereof. Concurrently with
                  such Holder ceasing to be a holder of Exchangeable Shares, the
                  Holder shall be considered and deemed for all purposes to be
                  the holder of the Amdocs Ordinary Shares issued to it pursuant
                  to the automatic exchange of Exchangeable Shares for Amdocs
                  Ordinary Shares and the certificates held by the Holder
                  previously representing the Exchangeable Shares exchanged by
                  the Holder with Holdco pursuant to such automatic exchange
                  shall thereafter be deemed to represent the Amdocs Ordinary
                  Shares delivered to the Holder by Holdco pursuant to such
                  automatic exchange. Upon the request of a Holder and the
                  surrender by the Holder of Exchangeable Share certificates
                  deemed to represent shares of Amdocs Ordinary Shares, duly
                  endorsed in blank and accompanied by such instruments of
                  transfer as Amdocs and Holdco may reasonably require, Holdco
                  shall deliver or


                                       18
<PAGE>   19
                  cause to be delivered to the Holder certificates representing
                  the Amdocs Ordinary Shares of which the Holder is the holder.

5.13     WITHHOLDING RIGHTS

                  Prior to the exchange or disposition of any Exchangeable
Shares in accordance with this Article, each Holder shall deliver to the
purchaser, at or before such time:

         (a)      a certificate confirming that such Holder is a resident of
                  Canada for the purposes of the ITA; or

         (b)      in the case of a Holder who is a non-resident of Canada for
                  the purposes of the ITA: (i) a certificate satisfactory to the
                  purchaser acting reasonably, issued pursuant to subsection
                  116(2) or 116(4) of the ITA, with respect to the Exchangeable
                  Shares, and having, in the case of a certificate under
                  subsection 116(2) as the "certificate limit", as defined in
                  subsection 116(2) of the ITA, an amount no less than the cost
                  to the purchaser of the Exchangeable Shares, as the case may
                  be; and (ii) if applicable, a certificate reasonably
                  satisfactory to the purchaser issued pursuant to Section 1098
                  of the Taxation Act (Quebec) or any other analogous
                  certificate required by any other provincial taxing authority.

                  In the case of a Holder who is a partnership, the Holder shall
also provide a certificate confirming the name and address of each member
thereof and the percentage of partnership interest held by each member (which
partners and percentages are clearly contemplated in the applicable
certificate).

                  In the event that a Holder fails to deliver the requisite
certificates described above at or before the exchange or disposition of such
shares, the purchaser of the Exchangeable Shares shall be entitled to deduct and
withhold from any consideration otherwise payable to any Holder such amounts as
the purchaser is required or permitted to deduct and withhold with respect to
such payment under the ITA or any provision of provincial or governmental tax
law, in each case, as amended or succeeded, provided that such withheld amount
shall not be remitted prior to two business days prior to the date such amount
is required by law to be remitted (the "Remittance Date") and where such
certificate is delivered prior to such Remittance Date, such withheld amount
shall be released. To the extent that amounts are so withheld, such withheld
amounts shall be treated for all purposes hereof as having been paid to the
Holder in respect of which such deduction and withholding was made, provided
that such withheld amounts are actually remitted to the appropriate taxing
authority. To the extent that the amount so required or permitted to be deducted
or withheld from any payment to a Holder exceeds the cash portion of the
consideration otherwise payable to the Holder, the purchaser, as agent of such
Holder, is hereby authorized to sell or otherwise dispose of such portion of the
consideration as is necessary to provide sufficient funds to the purchaser to
enable it to comply with such deduction or


                                       19
<PAGE>   20
withholding requirement and the purchaser shall notify the Holder thereof and
remit to such Holder any unapplied balance of the net proceeds of such sale. If
the proceeds of such sale are insufficient to fund the required withholding, the
Holder shall forthwith pay to the purchaser or remit to the applicable taxing
authority the deficiency. The Holder shall bear all reasonable costs and expense
associated with such sale by purchaser pursuant to the two immediately preceding
sentences.

succeeding to all or any part of the interest of any Holder in any Exchangeable
Shares resulting in conflicting claims or demands being made in connection with
such interest, then the Trustee shall be entitled, at its sole discretion, to
refuse to recognize or to comply with any such claim or demand. In so refusing,
the Trustee may elect not to exercise any Voting Rights, Exchange Right or
Automatic Exchange Rights subject to such conflicting claims or demands and, in
so doing, the Trustee shall not be or become liable to any person on account of
such election or its failure or refusal to comply with any such conflicting
claims or demands. The Trustee shall be entitled to continue to refrain from
acting and to refuse to act until:

         (a)      the rights of all adverse claimants with respect to the Voting
                  Rights, Exchange Right or Automatic Exchange Rights subject to
                  such conflicting claims or demands have been adjudicated by a
                  final judgment of a court of competent jurisdiction; or

         (b)      all differences with respect to the Voting Rights, Exchange
                  Right or Automatic Exchange Rights subject to such conflicting
                  claims or demands have been conclusively settled by a valid
                  written agreement binding on all such adverse claimants, and
                  the Trustee shall have been furnished with an executed copy of
                  such agreement.

                  If the Trustee elects to recognize any claim or comply with
any demand made by any such adverse claimant, it may in its discretion require
such claimant to furnish such surety bond or other security satisfactory to the
Trustee as it shall deem appropriate fully to indemnify it as between all
conflicting claims or demands.

7.16     ACCEPTANCE OF TRUST

                  The Trustee hereby accepts the Trust created and provided for
by and in this Agreement and agrees to perform the same upon the terms and
conditions herein set forth and to hold all rights, privileges and benefits
conferred hereby and by law in trust for the various persons who shall from time
to time be Holders, subject to all the terms and conditions herein set forth.

                                  COMPENSATION

8.1      FEES AND EXPENSES OF THE TRUSTEE

                  The Company shall pay to the Trustee reasonable compensation
for all of the services rendered by it under this Agreement and will reimburse
the Trustee for all reasonable expenses (including but not limited to taxes,
compensation paid to experts, agents and advisors and travel expenses) and
disbursements, including the cost and expense of any suit or litigation of any
character and any proceedings before any governmental agency reasonably incurred
by the Trustee in connection with its rights and duties under this Agreement;
provided that the Company shall have no obligation to reimburse the Trustee for
any expenses or disbursements paid, incurred or suffered by the Trustee in any
suit or litigation in which the Trustee is determined to have acted in bad faith
or with negligence, recklessness or willful misconduct.

                                    ARTICLE 9
                   INDEMNIFICATION AND LIMITATION OF LIABILITY

9.1      INDEMNIFICATION OF THE TRUSTEE

                  The Company shall indemnify and hold harmless the Trustee and
each of its directors, officers, employees and agents appointed and acting in
accordance with this Agreement (collectively, the "Indemnified Parties") against
all claims, losses, damages, costs, penalties, fines and reasonable expenses
(including reasonable expenses of the Trustee's legal counsel) which, without
fraud, negligence, recklessness, willful misconduct or bad faith on the part of
such Indemnified Party, may be paid, incurred or suffered by the Indemnified
Party by reason of or as a result of the Trustee's acceptance or administration
of the Trust, its compliance with its duties set forth in this Agreement, or any
written or oral instructions delivered to the Trustee by Amdocs or the Company
pursuant hereto. In no case shall the Company be liable under this indemnity for
any claim against any of the Indemnified Parties unless the Company shall be
notified by the Trustee of the written assertion of a claim or of any action
commenced against the Indemnified Parties, promptly after any of the Indemnified
Parties shall have received any such written assertion of a claim or shall have
been served with a summons or other first legal process giving information as to
the nature and basis of the claim. Subject to (ii), below, the Company shall be
entitled to participate at its own expense in the defense and, if the Company so
elects at any time after receipt of such notice, it may assume the defense of
any suit brought to enforce any such claim. The Trustee shall have the right to
employ separate counsel in any such suit and participate in the defense thereof
but the fees and expenses of such counsel shall be at the expense of the Trustee
unless: (i) the employment of such counsel has been authorized by the Company,
such authorization not to be unreasonably withheld; or (ii) the named parties to
any such suit include both the Trustee and Amdocs or the Company and the Trustee
shall have been advised by counsel acceptable to the Company that there may be
one or more legal defenses available to the Trustee that are different from or
in addition to those

                                       28
<PAGE>   29
available to Amdocs or the Company and that an actual or potential conflict of
interest exists (in which case the Company shall not have the right to assume
the defense of such suit on behalf of the Trustee but shall be liable to pay the
reasonable fees and expenses of counsel for the Trustee).

9.2      LIMITATION OF LIABILITY

                  The Trustee shall not be held liable for any loss which may
occur by reason of depreciation of the value of any part of the Trust Estate or
any loss incurred on any investment of funds pursuant to this Agreement, except
to the extent that such loss is attributable to the fraud, negligence, willful
misconduct or bad faith on the part of the Trustee.

                                CHANGE OF TRUSTEE

10.1     RESIGNATION

                  The Trustee, or any trustee hereafter appointed, may at any
time resign by giving written notice of such resignation to Amdocs and the
Company specifying the date on which it desires to resign, provided that such
notice shall never be given less than 60 days before such desired resignation
date unless Amdocs and the Company otherwise agree and provided further that
such resignation shall not take effect until the date of the appointment of a
successor trustee and the acceptance of such appointment by the successor
trustee. Upon receiving such notice of resignation, Amdocs and the Company shall
promptly appoint a successor trustee by written instrument in duplicate, one
copy of which shall be delivered to the resigning trustee and one copy to the
successor trustee. Failing acceptance by a successor trustee, a successor
trustee may be appointed by an order of the Court upon application of one or
more of the parties hereto.


10.2     REMOVAL

                  The Trustee, or any trustee hereafter appointed, may be
removed with or without cause, at any time on 30 days' prior notice by written
instrument executed by Amdocs and the Company, in duplicate, one copy of which
shall be delivered to the trustee so removed and one copy to the successor
trustee.

10.3     SUCCESSOR TRUSTEE

                  Any successor trustee appointed as provided under this
Agreement shall execute, acknowledge and deliver to Amdocs, Parentco, Holdco and
the Company and to its predecessor trustee an instrument accepting such
appointment. Thereupon the resignation or removal of the predecessor trustee
shall become effective and such successor trustee, without any further act, deed
or conveyance, shall become vested with all the rights, powers, duties and
obligations of its

                                       29
<PAGE>   30
predecessor under this Agreement, with like effect as if originally named as
trustee in this Agreement. However, on the written request of Amdocs, Parentco,
Holdco and the Company or of the successor trustee, the trustee ceasing to act
shall, upon payment of any amounts then due it pursuant to the provisions of
this Agreement, execute and deliver an instrument transferring to such successor
trustee all the rights and powers of the trustee so ceasing to act. Upon the
request of any such successor trustee, Amdocs, Parentco, Holdco, the Company and
such predecessor trustee shall execute any and all instruments in writing for
more fully and certainly vesting in and confirming to such successor trustee all
such rights and powers.

10.4     NOTICE OF SUCCESSOR TRUSTEE

                  Upon acceptance of appointment by a successor trustee as
provided herein, Amdocs and the Company shall cause to be mailed notice of the
succession of such trustee hereunder to each Holder specified in a List. If
Amdocs or the Company shall fail to cause such notice to be mailed within 10
days after acceptance of appointment by the successor trustee, the successor
trustee shall cause such notice to be mailed at the expense of the Company.

                                AMDOCS SUCCESSORS

11.1     CERTAIN REQUIREMENTS IN RESPECT OF COMBINATION, ETC.

                  Amdocs, directly or indirectly, shall not consummate any
transaction (whether by way of reconstruction, reorganization, consolidation,
merger, transfer, sale, lease or otherwise) whereby all or substantially all of
its undertaking, property and assets would become the property of any other
person or, in the case of a merger, of the continuing corporation resulting
therefrom unless, but may do so if:


         (a)      such other person or continuing corporation (herein called the
                  "Amdocs Successor"), by operation of law, becomes, without
                  more, bound by the terms and provisions of this Agreement or,
                  if not so bound, executes, prior to or contemporaneously with
                  the consummation of such transaction an agreement supplemental
                  hereto and such other instruments (if any) as are reasonably
                  satisfactory to the Trustee and in the opinion of legal
                  counsel to the Trustee are reasonably necessary or advisable
                  to evidence the assumption by the Amdocs Successor of Amdocs'
                  liability for all moneys payable and property deliverable by
                  Amdocs hereunder and the covenant of such Amdocs Successor to
                  pay and deliver or cause to be delivered the same and its
                  agreement to observe and perform all the covenants and
                  obligations of Amdocs under this Agreement; and

         (b)      such transaction shall, to the reasonable satisfaction of the
                  Trustee and in the opinion of legal counsel to the Trustee, be
                  upon such terms so as to substantially

                                       30
<PAGE>   31
                  preserve and not to impair in any material respect any of the
                  rights, interests, duties, powers and authorities of the
                  Trustee or of the Holders hereunder.

11.2     VESTING OF POWERS IN SUCCESSOR

                  Whenever the conditions of Section 11.1 hereof have been duly
observed and performed, the Amdocs Successor and the parties hereto, if required
by Section 11.1 hereof, shall execute and deliver the supplemental agreement
provided for in Section 12.5 hereof and thereupon Amdocs Successor shall possess
and from time to time may exercise each and every right and power of Amdocs
under this Agreement in the name of Amdocs or otherwise and any act or
proceeding by any provision of this Agreement required to be done or performed
by the Board of Directors of Amdocs or any officers of Amdocs may be done and
performed with like force and effect by the directors or officers of such Amdocs
Successor.

11.3     WHOLLY-OWNED SUBSIDIARIES

                  Nothing herein shall be construed as preventing the
amalgamation, merger or other combination of any wholly-owned direct or indirect
subsidiary of Amdocs with or into Amdocs or the winding-up, liquidation or
dissolution of any wholly-owned subsidiary of Amdocs provided that all of the
assets of such subsidiary are transferred to Amdocs or another wholly-owned
subsidiary of Amdocs, and any such transactions are expressly permitted by this
Article 11.

                  AMENDMENTS AND SUPPLEMENTAL TRUST AGREEMENTS

12.1     AMENDMENTS, MODIFICATIONS, ETC.

                  This Agreement may not be amended or modified except by an
agreement in writing executed by the Company, Amdocs, Parentco, Holdco and the
Trustee and approved by the Holders in accordance with Section 10.2 of the
Exchangeable Share Provisions.

12.2     ADMINISTRATIVE AMENDMENTS

                  Notwithstanding the provisions of Section 12.1 hereof, the
parties to this Agreement may in writing, at any time and from time to time,
without the approval of the Holders, amend or modify this Agreement for the
purposes of:

         (a)      adding to the covenants of any or all parties hereto for the
                  protection of the Holders hereunder provided that the Board of
                  Directors of each of the Company and Amdocs shall be of the
                  good faith opinion that such additions will not be prejudicial
                  to the rights or interests of the Holders;

                                       31
<PAGE>   32
         (b)      making such amendments or modifications not inconsistent with
                  this Agreement as may be necessary or desirable with respect
                  to matters or questions which, in the good faith opinion of
                  the Board of Directors of each of Amdocs and Company and in
                  the good faith opinion of the Trustee and its counsel, having
                  in mind the best interests of the Holders as a whole, it may
                  be expedient to make, provided that such boards of directors
                  and the Trustee and its counsel shall be of the good faith
                  opinion that such amendments and modifications will not be
                  prejudicial to the interests of the Holders as a whole; or

         (c)      making such changes or corrections which, on the advice of
                  counsel to the Company, Amdocs and the Trustee, are required
                  for the purpose of curing or correcting any ambiguity or
                  defect or inconsistent provision or clerical omission or
                  mistake or manifest error, provided that the Trustee and its
                  counsel and the Board of Directors of each of the Company and
                  Amdocs shall be of the good faith opinion that such changes or
                  corrections will not be prejudicial to the interests of the
                  Holders as a whole.

12.3     MEETING TO CONSIDER AMENDMENTS

                  The Company, at the request of Amdocs, shall call a meeting or
meetings of the Holders for the purpose of considering any proposed amendment or
modification requiring approval pursuant hereto. Holders may also approve any
proposed amendment or modification by written consent of Holders holding not
less than the minimum number of Exchangeable Shares that would be necessary to
authorize or take such action at a meeting of Holders called for such purpose.
Any such meeting or meetings shall be called and held, or written consent given
shall be given in accordance with the by-laws of the Company, the Exchangeable
Share Provisions and all applicable laws.

12.4     CHANGES IN CAPITAL OF AMDOCS AND THE COMPANY

                  At all times after the occurrence of any event effected
pursuant to Section 2.7 or Section 2.8 of the Support Agreement or otherwise, as
a result of which either Amdocs Ordinary Shares or the Exchangeable Shares or
both are in any way changed, this Agreement shall forthwith be amended and
modified as necessary in order that it shall apply with full force and effect,
mutatis mutandis, to all new securities into which the Amdocs Ordinary Shares or
the Exchangeable Shares or both are so changed and the parties hereto shall
execute and deliver a supplemental agreement giving effect to and evidencing
such necessary amendments and modifications.

                  No amendment to or modification or waiver of any of the
provisions of this Agreement otherwise permitted hereunder shall be effective
unless made in writing and signed by all of the parties hereto. From time to
time the Company, Amdocs, Parentco, Holdco and the Trustee may, subject to the
provisions of these presents, and they shall, when so directed by these
presents, execute and deliver by their proper officers, agreements or other
instruments supplemental hereto, which thereafter shall form part hereof, for
any one or more of the following purposes:

         (a)      evidencing the succession of Amdocs Successors to Amdocs and
                  the covenants of and obligations assumed by each such Amdocs
                  Successor in accordance with the provisions of Article 11 and
                  the successor of any successor trustee in accordance with the
                  provisions of Article 10;

         (b)      making any additions to, deletions from or alterations of the
                  provisions of this Agreement or the Voting Rights, the
                  Exchange Right or the Automatic Exchange Rights which, in the
                  opinion of the Trustee and its counsel, will not be
                  prejudicial to the interests of the Holders as a whole or are
                  in the opinion of counsel to the Trustee necessary or
                  advisable in order to incorporate, reflect or comply with any
                  legislation the provisions of which apply to Amdocs, Parentco,
                  Holdco, the Company, the Trustee or this Agreement; and

         (c)      for any other purposes not inconsistent with the provisions of
                  this trust agreement, including without limitation to make or
                  evidence any amendment or modification to this agreement as
                  contemplated hereby, provided that, in the opinion of the
                  Trustee and its counsel, the rights of the Trustee and the
                  Holders as a whole will not be prejudiced thereby.

13.1     TERM

                  The Trust created by this Agreement shall continue until the
earliest to occur of the following events:

         (a)      no outstanding Exchangeable Shares are held by a Holder (other
                  than Amdocs and its Affiliates);

         (b)      each of the Company and Amdocs elects in writing to terminate
                  the Trust and such termination is approved by the Holders of
                  the Exchangeable Shares in accordance with Section 10.2 of the

                  This Agreement shall survive any termination of the Trust and

Holder; provided, however, that the provisions of Articles 8 and 9 hereof shall
survive any such termination of this Agreement.

                                   ARTICLE 14
                                     GENERAL

14.1     SEVERABILITY

                  If any term or other provision of this Agreement is invalid,
illegal or incapable of being enforced by any rule or law, or public policy, all
other conditions and provisions of this Agreement shall nevertheless remain in
full force and effect so long as the economic or legal substance of the
transactions contemplated hereby is not affected in any manner materially
adverse to any party. Upon such determination that any term or other provision
is invalid, illegal or incapable of being enforced, the parties hereto shall
negotiate in good faith to modify this Agreement so as to effect the original
intent of the parties as closely as possible in an acceptable manner to the end
that the transactions contemplated hereby are fulfilled to the fullest extent
possible.


14.2     INUREMENT

                  This Agreement shall be binding upon and inure to the benefit
of the parties hereto, the holders of the Exchangeable Shares and their

heirs, executors, trustees, administrators and other personal representatives.
