Roth IRA/SEP IRA/SIMPLE IRA

The  section of the  Prospectus  entitled  "Purchasing  Annuities  - Uses of the
Annuity" is amended as follows:

The Annuity may be issued in connection  with or purchased as a funding  vehicle
for  certain  retirement  plans  designed  to meet the  requirements  of various
sections of the Code. These include,  but are not limited to: (a) Section 403(b)
(tax-sheltered   annuities   available  to   employees  of  certain   qualifying
employers);  (b) Section 408  (individual  retirement  accounts  and  individual
retirement  annuities  - "IRAs";  Simplified  Employee  Pensions  - "SEPs";  and
Savings  Incentive Match Plans for Employees - "SIMPLE  IRAs");  and (c) Section
408A (Roth IRAs).

The section of the Prospectus  entitled "Certain Tax Considerations - Penalty on
Distributions" is amended as follows:

 With respect to Roth IRAs only, distributions are not subject to federal income
tax or the 10%  penalty  tax if five (5) tax years have  passed  since the first
contribution was made or any conversion from a traditional IRA was made, and the
distribution is made (a) once the taxpayer is age 59 1/2 or older,  (b) upon the
death or disability of the taxpayer,  or (c) for qualified first-time home buyer
expenses, subject to certain limitations. Distributions from a Roth IRA that are
not "qualified" as described above may be subject to a penalty tax.












Wells XT/WellsVA+  (3/98)

The section of the Prospectus  entitled "Certain Tax Considerations - Individual
Retirement Programs" is amended as follows:

Eligible individuals may maintain an individual retirement account or individual
retirement  annuity  ("IRA").  Subject to limitations,  contributions of certain
amounts may be deductible  from gross  income.  Such persons may also maintain a
form of IRA called a "Roth IRA".  Contributions to a Roth IRA are not deductible
but,  under  certain  circumstances,  distributions  from  such an  account  are
tax-free.  Purchasers  of IRAs and Roth IRAs will  receive a special  disclosure
document,   which   describes   limitations   on   eligibility,   contributions,
transferability and distributions.  It also describes the conditions under which
distributions  from IRAs and qualified  plans may be rolled over or  transferred
into an IRA on a tax-deferred basis and the conditions under which distributions
from  traditional  IRAs may be rolled over to, or the traditional IRA itself may
be converted into a Roth IRA.  Eligible  employers that meet specified  criteria
may establish savings incentive match plans for employees or Simplified Employee
Pensions using the employees' IRAs. These  arrangements are known as SIMPLE IRAs
and others as SEP IRAs.  Employer  contributions that may be made to SIMPLE IRAs
and SEP IRAs are larger than the amounts that may be  contributed to other IRAs,
and may be deductible to the employer.
