follows:

         (a) On each Reset Date,  the Servicer will  determine the LIBOR Rate on
         the basis of the rate for deposits in U.S.  Dollars for a period of one
         month that appears on Bloomberg MMR2 or, if unavailable,  Telerate Page
         3750, as of 11:00 a.m. (London time) on such Reset Date.

         the  rates  at  which  deposits  in U.S.  Dollars  are  offered  by the
         Reference Banks at approximately  11:00 a.m. (London time) on such date

<PAGE>


         Servicer  will  request  the  principal  London  office  of each of the
         Reference Banks to provide such a quotation. If, on any Reset Date: (i)
         at least two Reference Banks provide  quotations  when  requested,  the
         LIBOR  Rate for such  Reset  Date  will be the  arithmetic  mean of the
         quotations so received; or (ii) only one or none of the Reference Banks
         provides such a quotation,  the LIBOR Rate will be the arithmetic  mean
         of the offered rates quoted by major banks in New York City selected by
         the Servicer at  approximately  11:00 a.m. (New York City time) on such
         Reset Date for loans to leading  European  banks in U.S.  Dollars for a
         period of one month commencing on that Reset Date.

Certificates that is derived from its pro rata share of the Series Percentage of
interest due on the Loans less the Series Percentage of Scheduled Expenses, with
such pro ration based upon the relative rate at which interest otherwise accrues

Certificates in this Series shall be as otherwise adjusted pursuant to Section 4
hereof.

Funding Termination Date, an amount,  payable to *** to the account specified in
Annex 2 to the  Certificate  Purchase  Agreement,  equal to the  product  of (a)

proceeds  being  used to  prepay  all 98-1  Revolving  Certificates  by Class in
reverse order of issuance;  provided that no such  prepayment of 98-1  Revolving
                            --------

downward,  as  appropriate.  Notwithstanding  the foregoing,  the Maximum Series
Amounts and Minimum Funding  Amounts shall not be increased  without the consent
of the Holders of Certificates in the relevant Class, and the  Certificateholder
Agent shall use its best efforts to obtain any required approvals.

         In addition, on any Funding Date: (i) the Class D-R Certificates may be
prepaid,  without premium or penalty, in the amount of any Excess Funding Amount
being  funded on such date by the  Holders of Rated  Certificates;  and (ii) the
Maximum  Series  Amount for the Class D-R  Certificates  shall be  increased  if
required by the Rating Agency to maintain the rating of any Certificates of this
Series in  connection  with a  specific  Funding  that  involves  Loans that are
permitted to deviate from the Program Guidelines or the Pool Criteria.

         The parties  agree that the  aggregate  amount of each Funding  under a
Term Series shall be at least $15,000,000.

the Controlling Holders.

         The   Certificates   of  this  Series  shall  be  issuable  in  minimum
denominations greater than $100,000 which denominations shall be, in the case of
the Class A-R Certificates, integral multiples of $500, in the case of the Class
B-R and Class C-R Certificates,  integral  multiples of $105, and in the case of

       -----------                       ----------  
undivided  fractional  interest in the Allegiance  Capital Trust I (the "Trust")
formed by Allegiance  Funding Corp. I (the  "Depositor").  The Trust was created
pursuant  to the  Trust  Agreement,  dated  as of  August  1,  1998,  among  the
Depositor,  Manufacturers and Traders Trust Company, as Trustee (the "Trustee"),
and Point West Capital  Corporation,  as Servicer,  and the  Supplement to Trust
Agreement for Revolving  Series  1998-1,  dated as of August 1, 1998,  among the
Depositor,  the  Trustee  and  Point  West  Capital  Corporation,   as  Servicer
(collectively, the "Trust Agreement").  Reference is made to the Trust Agreement
for a statement  of the  respective  rights  thereunder  of the  Depositor,  the
Trustee  and the  Holders  of the  Certificates,  and the terms  upon  which the
Certificates are, and are to be, authenticated and delivered.  To the extent not
otherwise  defined  herein,  each  capitalized  term used herein has the meaning
assigned to it in the Trust Agreement.

         This  Certificate  is one of a duly  authorized  issue of  Certificates
designated  as the Class A-R  Revolving  Certificates,  Series  1998-1  having a
scheduled  maturity of August 16, 1999 and a Series Termination Date of July 15,
2019 (herein called the "Class A-R Certificates")  issued and to be issued under
the Trust  Agreement.  This Class A-R Certificate is issued under and is subject
to the terms,  provisions and conditions of the Trust Agreement,  to which Trust
Agreement  the holder of this Class A-R  Certificate  by virtue of such Holder's
acceptance hereof assents and by which such Holder is bound.

         The Holder of this  Certificate  is obligated  to provide  funds to the
Depositor  on each  Funding  Date  during  the  Funding  Period  subject  to the
applicable  terms and conditions  set forth in the  Transaction  Documents.  The
Fundings  made by the  Holder  of this  Certificate  to the  Depositor  shall be
evidenced by this  Certificate  and the  Certificateholder  shall endorse on the
schedule  annexed  hereto and made a part  hereof,  or elsewhere in its internal
records, the date and amount of each Funding made by it to the Depositor and the
amount of each payment of principal made by the Depositor with respect  thereto.
The Certificateholder is authorized and directed by the Depositor to endorse the
schedule   attached  hereto  or  maintain  such  records;   provided  that  each
                                                            --------
Certificateholder's  endorsements or records shall be effective only if they are
in agreement with the register maintained by the Trustee,  absent manifest error
in such register.  The failure of the  Certificateholder to make, or an error in
making,  a notation  with  respect to any Funding  shall not limit or  otherwise
affect the obligations of the Depositor  hereunder or under the Trust Agreement.
The aggregate  amount of all Fundings made by the Holder of this Certificate (as
reduced by any amounts  distributed  as  principal  during the Funding  Period),
pursuant to this Certificate, shall not exceed ($        ).
                                                 --------
         This Class A-R Certificate bears interest during each Accrual Period on
the  Outstanding  Principal  Amount  hereof (as of the first day of the  Accrual
Period) at the  Certificate  Interest  Rate,  until and  including  the last day
preceding the Payment Date on which the Outstanding  Principal Amount hereof has
been reduced to zero. Interest on the Outstanding  Principal Amount hereof shall
be calculated on the basis of a 360-day year  consisting of 12 months of 30 days
each.  Interest  shall be due and payable in arrears on each  Payment  Date.  In
addition,  with  respect to any  Funding by the Class A-R  Certificates  of this
Series occurring in any Accrual Period following the preceding Payment Date, the
related  Funding  Amounts shall accrue  interest  from the related  Funding Date
through the end of the Accrual Period in which such Funding occurs in the amount
of the  applicable  First Period  Interest,  which interest shall be paid on the
next  Payment  Date.  The First Period  Interest on the Funding  Amount shall be
determined on the Funding Date at the rate  established on the applicable  Reset
Date. Notwithstanding the foregoing, if the Outstanding Principal Amount of this
Certificate is not paid in full by its Scheduled Maturity, then, for any Accrual
Period 

                                      A-2

<PAGE>



commencing on or after such Scheduled Maturity, the Floating Rate Spread on this
Certificate shall be increased by 1.00%. In making any interest payment,  if the
interest  calculation with respect to a Certificate shall result in a portion of
such payment being less than $0.01,  then such payment shall be decreased to the
nearest  whole  cent,  and no  subsequent  adjustment  shall be made in  respect
thereof.

         The  principal  of this  Class  A-R  Certificate  shall be  payable  in
installments  ending no later than the Series Termination Date unless this Class
A-R  Certificate  becomes  due and  payable  at an  earlier  date  by  call  for
redemption or otherwise.  All reductions in the principal  amount of a Class A-R
Certificate  effected by  payments  of  installments  of  principal  made on any
Payment  Date  shall be  binding  upon all  future  Holders  of this  Class  A-R
Certificate  and of any Class A-R  Certificate  issued upon the  registration of
transfer  hereof or in exchange  herefor or in lieu hereof,  whether or not such
payment is noted on this Class A-R  Certificate.  Each  installment of principal
payable  on this  Class  A-R  Certificate  shall be in an  amount  equal to this
Certificateholder's  pro rata  share of the  Class  A-R  Principal  Distribution
Amount  available to be paid in accordance  with the  priorities of Section 3 of
the Supplement for this Series and Section 5.02 of the Trust Agreement.  Subject
to the terms of the Trust  Agreement,  the  principal  payable on this Class A-R
Certificate  shall be paid on each  Payment  Date  during  the term of the Trust
Agreement, beginning on the Initial Payment Date. All payments of principal with
respect to all of the Class A-R  Certificates of a Series shall be made on a pro
rata basis based upon the ratio that the Outstanding Principal Amount of a Class
A-R  Certificate  bears to the  Outstanding  Principal  Amount  of all Class A-R
Certificates  of such Series;  provided that, if as a result of such proration a
portion of such principal  would be less than $0.01,  then such payment shall be
reduced to the nearest whole cent.

         In addition,  the Certificate  Prepayment Fee Amount,  if any, shall be
distributed on each Payment Date to the Holders of the Class A-R Certificates to
the extent such Class is receiving a distribution of Prepaid Principal Amount on
such date.  All payments of  Certificate  Prepayment Fee Amounts with respect to
the Class A-R  Certificates  shall be made  prorata  based upon the ratio of the
Outstanding  Principal Amount of this  Certificate to the Outstanding  Principal
Amount of Class A-R Certificates of this Series, provided that if as a result of
such  proration,  a portion of such payment would be less than $0.01,  then such
payment shall be reduce to the nearest whole cent.

         The  interest and  principal  so payable on any Payment  Date will,  as
provided  in the  Trust  Agreement,  be paid to the  Person  in whose  name this
Certificate is registered on the Record Date for such Payment Date,  which shall
be the close of business on the last day of the month prior to such Payment Date
(whether or not a Business Day). The principal and interest on this  Certificate
are  payable by wire  transfer  in  immediately  available  funds to the account
specified  in writing to the  Trustee  by the Person  whose name  appears as the
Registered  Holder of this Certificate on the Certificate  Register  received at
least five (5)  Business  Days prior to the Record Date for the Payment Date (or
if no such  account  is  specified  or if such wire  fails,  by check  mailed by
first-class  mail to the Person whose name appears as the  Registered  Holder of
this Certificate on the Certificate Register at the address of such Person as it
appears on the  Certificate  Register),  in such coin or  currency of the United
States of  America as at the time of  payment  is legal  tender  for  payment of
public and private debts. Funds represented by checks returned  undelivered will
be held for payment to the Person entitled thereto,  subject to the terms of the
Trust  Agreement,  at the  office  or  agency in the  United  States of  America
designated  as such by the  Depositor  for such  purpose  pursuant  to the Trust
Agreement.

         The Depositor has structured the Trust  Agreement and the  Certificates
with the intention that the Trust be treated as a  partnership,  with the assets
of the  partnership  including  all of the  assets of the Trust  Estate  and the
partners  of  the  partnership  being  all  of the  Certificateholders  and  the
Depositor.  The Depositor, the Trustee, the Servicer and each Certificateholder,
by acceptance of its Certificate  (and any 

                                      A-3

<PAGE>

Person that is a beneficial owner of any interest in a Certificate, by virtue of
such Person's acquisition of a beneficial interest therein), agree to report the
transactions  contemplated  thereby in  accordance  with such stated  intentions
unless and until determined to the contrary by an applicable taxing authority.

         The  property  of the Trust  Estate  includes  certain  Loan Assets and
certain  other  assets  described  in  the  Trust   Agreement.   The  Class  A-R
Certificates of the 1998-1 Series and all other Series of Class A-R Certificates
issued under the Trust  Agreement are payable out of the Trust Estate pari passu
among such Class A-R  Certificateholders  equally and ratably without prejudice,
priority or distinction  between any Class A-R  Certificate by reason of time of
issue or otherwise. The Class A-R Certificates are payable only out of the Trust
Estate and do not represent  recourse  obligations of the Depositor,  Allegiance
Capital,  LLC or any of their  respective  affiliates or  successors.  The Trust
Agreement  pursuant to which this Class A-R  Certificate is issued also provides
for the issuance of other Classes and Series of Certificates  from time to time.
Payments of interest on the Class A-R  Certificates  are senior to such payments
on other  Classes  having a lower credit  rating from the Rating  Agency and are
subordinate to payments of interest on any Classes having a higher credit rating
form the Rating Agency.  Payments of principal in the Class A-R Certificates are
senior to payments of principal on other  classes  having a lower credit  rating
from the Rating Agency and are  subordinate to such payments on any Class having
a higher credit rating from the Rating Agency.

         Unless the Depositor  exercises its Optional  Termination  rights,  the
Certificates  are  payable  only at the time and in the manner  provided  in the
Trust  Agreement  and are not  redeemable  or  prepayable  at the  option of the
Depositor  before such time,  except that the  Depositor  may cause the Trust to
prepay on a dollar for dollar basis the principal,  without  penalty or premium,
of any  Outstanding  Series of Revolving  Certificates  with the proceeds of the
issuance of a Series of Term Certificates.

         As provided in the Trust  Agreement and subject to certain  limitations
therein set forth,  the transfer of this  Certificate  may be  registered on the
Certificate  Register of the Depositor  upon surrender of this  Certificate  for
registration  of transfer at the office or agency of the Depositor in the United
States of America maintained for such purpose,  duly endorsed by, or accompanied
by a written  instrument  of transfer  in form  reasonably  satisfactory  to the
Depositor and the Trustee and duly executed by the holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Class A-R Certificates
of the same  Scheduled  Maturity of  authorized  denominations  and for the same
initial aggregate principal amount will be issued to the designated transferees.

         Prior  to  due  presentment  for   registration  of  transfer  of  this
Certificate,  the  Depositor,  the Trustee and any agent of the Depositor or the
Trustee shall treat the Person in whose name this  Certificate  is registered as
the owner hereof for the purpose of receiving payment as herein provided and for
all other purposes whether or not this  Certificate be overdue,  and neither the
Depositor,  the  Trustee,  nor any such agent shall be affected by notice to the
contrary.

         The Holder of this  Certificate,  by  acceptance  of this  Certificate,
agrees that for one year and one day after it has been paid hereunder, it or any
Affiliate thereof will not file any involuntary  petition or otherwise institute
any   bankruptcy,   reorganization,   arrangement,   insolvency  or  liquidation
proceeding or other  proceeding under any federal or state bankruptcy or similar
law against the Depositor.

         The  Trust  Agreement  permits,  with  certain  exceptions  as  therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of the Depositor and the rights of the Holders of the  

                                      A-4

<PAGE>

Certificates under the Trust Agreement at any time by the Depositor, the Trustee
and the Servicer without the consent of the Holders of the Certificates.

         The  Certificates  are issuable only in registered form without coupons
in such authorized  denominations as provided in the Trust Agreement and subject
to certain limitations therein set forth.

         This Class A-R Certificate and the Trust Agreement shall be governed by
and  construed in  accordance  with the internal  laws of the State of New York,
without regard to conflicts of laws principles.

         No  reference  herein to the Trust  Agreement  and no provision of this
Class  A-R  Certificate  or of the Trust  Agreement  shall  alter or impair  the
obligation  of the Trust  Estate to pay the  principal  of and  interest on this
Class A-R  Certificate,  but solely from the assets of the Trust  Estate and the
Class A-R Certificate  Insurance Policy at the times, place and rate, and in the
coin or currency, herein prescribed.

Holder's acceptance hereof assents and by which such Holder is bound.

         The Holder of this  Certificate  is obligated  to provide  funds to the
Depositor  on each  Funding  Date  during  the  Funding  Period  subject  to the
applicable  terms and conditions  set forth in the  Transaction  Documents.  The

                                                 ---------
         This Class B-R Certificate bears interest during each Accrual Period on
the  Outstanding  Principal  Amount  hereof (as of the first day of the  Accrual
Period) at the  Certificate  Interest  Rate,  until and  including  the last day
preceding the Payment Date on which the Outstanding  Principal Amount hereof has
been reduced to zero. Interest on the Outstanding  Principal Amount hereof shall
be calculated on the basis of a 360-day year  consisting of 12 months of 30 days
each.  Interest  shall be due and payable in arrears on each  Payment  Date.  In
addition,  with  respect to any  Funding by the Class B-R  Certificates  of this
Series occurring in any Accrual Period following the preceding Payment Date, the
related  Funding  Amounts shall accrue  interest  from the related  Funding Date
through the end of the Accrual Period in which such Funding occurs in the amount
of the  applicable  First Period  Interest,  which interest shall be paid on the
next  Payment  Date.  The First Period  Interest on the Funding  Amount shall be
determined on the Funding Date at the rate  established on the applicable  Reset
Date. Notwithstanding the foregoing, if the Outstanding Principal Amount of this
Certificate is not paid in full by its Scheduled Maturity, then, for any Accrual
Period  commencing on or after such  Scheduled  Maturity,  the  Applicable  Rate
Spread on this  Certificate  shall be increased by 1.00%. In making any interest
payment, if the interest  calculation with respect to a Certificate

                                      B-2

<PAGE>

shall  result in a portion  of such  payment  being less than  $0.01,  then such
payment  shall  be  decreased  to the  nearest  whole  cent,  and no  subsequent
adjustment shall be made in respect thereof.

         The  principal  of this  Class  B-R  Certificate  shall be  payable  in
installments  ending no later than the Series Termination Date unless this Class
B-R  Certificate  becomes  due and  payable  at an  earlier  date  by  call  for
redemption or otherwise.  All reductions in the principal  amount of a Class B-R
Certificate  effected by  payments  of  installments  of  principal  made on any
Payment  Date  shall be  binding  upon all  future  Holders  of this  Class  B-R
Certificate  and of any Class B-R  Certificate  issued upon the  registration of
transfer  hereof or in exchange  herefor or in lieu hereof,  whether or not such
payment is noted on this Class B-R  Certificate.  Each  installment of principal
payable  on this  Class  B-R  Certificate  shall be in an  amount  equal to this
Certificateholder's  pro rata  share of the  Class  B-R  Principal  Distribution
Amount  available to be paid in accordance  with the  priorities of Section 3 of
the Supplement for this Series and Section 5.02 of the Trust Agreement.  Subject
to the terms of the Trust  Agreement,  the  principal  payable on this Class B-R
Certificate  shall be paid on each  Payment  Date  during  the term of the Trust
Agreement, beginning on the Initial Payment Date. All payments of principal with
respect to all of the Class B-R  Certificates of a Series shall be made on a pro
rata basis based upon the ratio that the Outstanding Principal Amount of a Class
B-R  Certificate  bears to the  Outstanding  Principal  Amount  of all Class A-R
Certificates  of such Series;  provided that, if as a result of such proration a
                               --------
portion of such principal  would be less than $0.01,  then such payment shall be
reduced to the nearest whole cent.

         In addition,  the Certificate  Prepayment Fee Amount,  if any, shall be
distributed on each Payment Date to the Holders of the Class B-R Certificates to
the extent such Class is receiving a distribution of Prepaid Principal Amount on
such date.  All payments of  Certificate  Prepayment Fee Amounts with respect to
the Class B-R  Certificates  shall be made  prorata  based upon the ratio of the
Outstanding  Principal Amount of this  Certificate to the Outstanding  Principal
Amount of all Class  B-R  Certificates  of this  Series,  provided  that if as a
result of such  proration,  a portion of such payment  would be less than $0.01,
then such payment shall be reduce to the nearest whole cent.

         The  interest and  principal  so payable on any Payment  Date will,  as
provided  in the  Trust  Agreement,  be paid to the  Person  in whose  name this
Certificate is registered on the Record Date for such Payment Date,  which shall
be the close of business on the last day of the month prior to such Payment Date
(whether or not a Business Day). The principal and interest on this  Certificate
are  payable by wire  transfer  in  immediately  available  funds to the account
specified  in writing to the  Trustee  by the Person  whose name  appears as the
Registered  Holder of this Certificate on the Certificate  Register  received at
least five (5)  Business  Days prior to the Record Date for the Payment Date (or
if no such  account  is  specified  or if such wire  fails,  by check  mailed by
first-class  mail to the Person whose name appears as the  Registered  Holder of
this Certificate on the Certificate Register at the address of such Person as it
appears on the  Certificate  Register),  in such coin or  currency of the United
States of  America as at the time of  payment  is legal  tender  for  payment of
public and private debts. Funds represented by checks returned  undelivered will
be held for payment to the Person entitled thereto,  subject to the terms of the
Trust  Agreement,  at the  office  or  agency in the  United  States of  America
designated  as such by the  Depositor  for such  purpose  pursuant  to the Trust
Agreement.

         The Depositor has structured the Trust  Agreement and the  Certificates
with the intention that the Trust be treated as a  partnership,  with the assets
of the  partnership  including  all of the  assets of the Trust  Estate  and the
partners  of  the  partnership  being  all  of the  Certificateholders  and  the
Depositor.  The Depositor, the Trustee, the Servicer and each Certificateholder,
by acceptance of its Certificate  (and any Person that is a beneficial  owner of
any  interest in a  Certificate,  by virtue of such  Person's  acquisition  of a
beneficial  interest  therein),  agree to report the  transactions  contemplated
thereby in accordance with such stated intentions unless and until determined to
the contrary by an applicable taxing authority.

Certificates  are  payable  only at the time and in the manner  provided  in the
Trust  Agreement  and are not  redeemable  or  prepayable  at the  option of the
Depositor  before such time,  except that the  Depositor  may cause the Trust to
prepay on a dollar for dollar basis the principal,  without  penalty or premium,
of any  Outstanding  Series of Revolving  Certificates  with the proceeds of the
issuance of a Series of Term Certificates.

         As provided in the Trust  Agreement and subject to certain  limitations

States of America maintained for such purpose,  duly endorsed by, or accompanied
by a written  instrument  of transfer  in form  reasonably  satisfactory  to the
Depositor and the Trustee and duly executed by the holder hereof or his attorney
duly authorized in writing, and thereupon one or more new Class B-R Certificates
having  the  same  Scheduled  Maturity,   Series  Termination  Date,  authorized
denomination(s)  and for the same  initial  aggregate  principal  amount will be
issued to the designated transferees.

         Prior  to  due  presentment  for   registration  of  transfer  of  this
Certificate,  the  Depositor,  the Trustee and any agent of the Depositor or the

petition or otherwise  institute any  bankruptcy,  reorganization,  arrangement,
insolvency or liquidation  proceeding or other  proceeding  under any federal or
state bankruptcy or similar law against the Depositor.

         The  Trust  Agreement  permits,  with  certain  exceptions  as  therein
provided,  the  amendment  thereof  and  the  modification  of  the  rights  and
obligations  of the Depositor and the rights of the Holders of the  Certificates
under the Trust  Agreement  at any time by the  Depositor,  the  Trustee and the
Servicer without the consent of the Holders of the Certificates.

         The  Certificates  are issuable only in registered form without coupons
in such authorized  denominations as provided in the Trust Agreement and subject
to certain limitations therein set forth.
