servicing agreement, to be entered into by and among Structured Asset Securities
Corporation (the "Registrant") and a master servicer, a special servicer and a
trustee. It is expected that certain classes of the Certificates (the
"Underwritten Certificates") will be registered under the Registrant's

Inc., Warburg Dillon Read LLC, Morgan Stanley & Co. Incorporated and Deutsche

            o     Newly Originated Collateral. The collateral consists of 190
                  mortgage loans (the "Mortgage Loans") with a principal
                  balance, as of March 11, 2000 (the "Cut-Off Date"), of
                  approximately $1.37 billion. All of the mortgage loans were
                  originated by affiliates of Lehman Brothers Inc. as well as

                  Loans prohibit voluntary prepayments but permit defeasance for
                  some part of their remaining terms. The Mortgage Loans are
                  generally prepayable without penalty between zero to six
                  months from Mortgage Loan maturity or anticipated repayment
                  date ("ARD"), with a weighted average open period of 2.5
                  months.

            o     57.4% Weighted Average LTV at Balloon (excluding CTL loans but
                  including other fully amortizing loans).

                  Tenant Lease ("CTL"), 1.0% Self Storage, and 0.7% Mixed Use.

            o     Geographic Distribution (by balance). The properties are

                  addition to detailed P&I payment and delinquency information.
                  Quarterly NOI and Occupancy information to the extent
                  delivered by borrowers, will be available to
                  Certificateholders.

            o     Cash flows will be modeled on BLOOMBERG.

                  Except as otherwise indicated, percentages (%) represent the
                  scheduled principal balance of the subject loan or loans as of
                  the Cut-Off Date (as to each loan, the "Cut-Off Date Balance")
                  compared to aggregate mortgage pool balance as of the Cut-Off
                  Date (the "Initial Pool Balance"); weighted averages are
                  weighted using Cut-Off Date Balance; loans with properties in
                  multiple states have been allocated to certain states based
                  upon "allocated loan amounts" or appraisal amount if the loan
                  did not have allocated loan amounts.

                              correspondents of those affiliates. As of the
                              Cut-off Date, the Mortgage Loans have a weighted
                              average coupon ("WAC") of 8.336% and a weighted

                              months (assuming that the ARD loans mature on
                              their ARD date). See the Collateral Overview
                              Tables at the end of this memo for more Mortgage

                                          Private Classes, sequentially.

                              *     A-1 and A-2 Classes are pro rata if Classes
                                    B through P are retired.

REALIZED LOSSES:              Realized Losses from any Mortgage Loan will be
                              allocated in reverse sequential order (i.e.
                              Classes P, N, M, L, K, J, H, G, F, E, D, C and B,
                              in that order). If Classes B through P have been
                              retired by losses, Realized Losses shall be
                              applied to the then existing A Classes pro-rata.

APPRAISAL REDUCTIONS:         With respect to certain specially serviced
                              Mortgage Loans as to which an appraisal is
                              required, including any Mortgage Loan that becomes
                              60 days delinquent, an Appraisal Reduction Amount
                              may be created, generally in the amount, if any,
                              by which the Stated Principal Balance of such
                              Mortgage Loan, together with unadvanced interest,
                              unreimbursed P&I advances and certain other items,
                              exceeds 90% of the appraised value of the related
                              Mortgaged Property. The Appraisal Reduction Amount
                              will reduce proportionately the P&I Advance for
                              that loan, which reduction may result in a
                              shortfall of interest to the most subordinate
                              class of Principal Balance Certificates
                              outstanding. The Appraisal Reduction Amount will
                              be reduced to zero as of the date the related
                              Mortgage Loan has been brought current for a
                              specified number of months, paid in full,
                              repurchased or otherwise liquidated, and any
                              shortfalls borne by the subordinate classes may be
                              paid from amounts recovered from the related
                              borrower.

CREDIT TENANT
LEASE LOANS:                  Credit Tenant Lease Loans are secured by mortgages
                              on properties which are leased (each a "Credit
                              Tenant Lease") to a tenant which possesses (or
                              whose parent or other affiliate which guarantees
                              the lease obligation possesses) the rating
                              indicated in the following table. Scheduled
                              monthly rent payments under the Credit Tenant
                              Leases are generally sufficient to pay in full and
                              on a timely basis all interest and principal
                              scheduled to be paid with respect to the related
                              Credit Tenant Lease Loans.

                              The Credit Tenant Lease Loans generally provide
                              that the tenant is responsible for all costs and
                              expenses incurred in connection with the
                              maintenance and operation of the related Credit
                              Tenant Lease property and that, in the event of a
                              casualty or condemnation of a material portion of
                              the related Mortgaged Property:

                                    (i)   the Tenant is obligated to continue
                                          making payments;

                                    (ii)  the Tenant must make an offer to
                                          purchase the applicable property
                                          subject to the Credit Tenant Lease for
                                          an amount not less than the unpaid
                                          principal balance plus accrued
                                          interest on the related Credit Tenant
                                          Lease Loan; or

                                    (iii) the Trustee on behalf of the
                                          Certificateholders will have the
                                          benefit of certain non-cancelable
                                          credit lease enhancement policies
                                          obtained to cover certain casualty
                                          and/or condemnation risks.

                              Approximately 2.3% of the Mortgage Loans are
                              Credit Tenant Lease Loans.

SIGNIFICANT
MORTGAGE LOANS:               There are four loans with a Cut-Off Date principal
                              balance in excess of $50 million. Each of the
                              large loans has been bifurcated into an A Note and
                              a B Note. The A Note has been deposited into the
                              Trust and will pay principal and interest to the
                              Trust, with the B Note, paying interest only until
                              the A Note is retired. Each B Note or securities
                              backed thereby will be rated investment grade by
                              Fitch. The following table provides a summary of

PREPAYMENT PREMIUM ALLOCATION EXAMPLE:

                              The yield maintenance charge due in connection
                              with a prepayment will generally be equal to the
                              present value of the reduction in interest
                              payments as a result of the prepayment through the
                              maturity of the prepaid Mortgage Loan, discounted
                              at the yield (converting from semi-annual to
                              monthly pay) of a Treasury security of similar
                              maturity in most cases, assuming ARD loans mature
                              on their anticipated repayment dates.

                              A portion of any collected prepayment premium will
                              be paid on the Class of Principal Balance
                              Certificates senior to the Class J Certificates
                              then receiving principal based on the Discount
                              Rate Fraction Methodology. The following example
                              reflects that method. The balance of the
                              prepayment premium will be distributed to the
                              Class X Certificates.

ANTICIPATED REPAYMENT DATE LOANS:

                              Mortgage Loans representing 51.4% of the Initial
                              Pool Balance provided that if the unamortized
                              principal amount thereof is not repaid on a date
                              (the "Anticipated Repayment Date") set forth in
                              the related Mortgage Note, the Mortgage Loan will
                              accrue additional interest at the rate set forth
                              therein and the borrower will be required to apply
                              excess monthly cash flow generated by the
                              Mortgaged Property (as determined in the related
                              Mortgage) to the repayment of principal
                              outstanding on the Mortgage Loan. With respect to
                              such Mortgage Loans, no prepayment consideration
                              will be due in connection with any principal
                              prepayment on or after the Anticipated Repayment
                              Date. For purposes of analysis and presentation,
                              such loans are assumed to pay off at the ARD and
                              are treated like balloon loans that mature on the
                              ARD.

ADVANCING:                    The Master Servicer will be obligated to make
                              advances of scheduled principal and interest
                              payments (excluding balloon payments and subject
                              to reduction for Appraisal Reduction Amounts) and

                              extent that such Advances are deemed to be
                              recoverable out of collections on the related
                              loan. If the Master Servicer fails to make a
                              required Advance, the Trustee will be obligated to

                              subject to certain limitations, be entitled to
                              replace the Special Servicer. Such holders of the
                              Controlling Class will also have the right to
                              direct or advise the Special Servicer with respect
                              to special servicing actions subject to the
                              servicing standards set in the Pooling and

                              amount of such B Note, the holder of such B Note

                              Special Servicer with respect to special servicing
                              actions for such Mortgage Loan and the
                              corresponding B Note.

Prepayment Premium Allocation Example:

The yield maintenance charge due in connection with a prepayment will generally
be equal to the present value of the reduction in interest payments as a result
of the prepayment through the maturity of the prepaid Mortgage Loan, discounted
at the yield (converted from semi-annual to monthly pay) of a Treasury security
of similar maturity in most cases, assuming ARD loans mature on their
Anticipated Repayment Dates.

A portion of any collected prepayment premium will be paid on the Class of
Principal Balance Certificates senior to the Class J Certificates then receiving
principal based on the Discount Rate Fraction Methodology. The following example
reflects that method. The balance of the prepayment premium will be distributed
to the Class X Certificates.
