$6,600,000                                                     April 29, 1997


                             SECURED PROMISSORY NOTE

FOR VALUE RECEIVED, the undersigned, 710 RT. 46 REALTY, LLC., a limited 
liability company organized under New Jersey law, and whose principal place 
of business is c/o Principal Investment Group, 950 3rd Avenue, 31st floor, 
New York, New York 10022 (the "Borrower"), promises to pay SIX MILLION SIX 
HUNDRED THOUSAND DOLLARS ($6,600,000), together with interest according to 
the terms of this secured promissory note (the "Note"), to the order of LIFE 
INVESTORS INSURANCE COMPANY OF AMERICA, an Iowa corporation (together with 
any future holder, (the "Lender"), whose address is c/o AEGON USA Realty 
Advisors, Inc., 4333 Edgewood Road, N.E., Cedar Rapids, Iowa 52499-5223.

1.   CONTRACT INTEREST RATE

     The principal balance of this Note shall bear interest at the rate of 
     eight and twenty nine one hundredths percent (8.29%) per annum (the 
     "Note Rate"). Interest shall be calculated on the basis of a 360-day 
     year and computed each month in arrears on the basis of a 30-day month.

2.   SCHEDULED PAYMENTS

     A)   PREPAYMENT OF INTEREST FOR THE MONTH OF FUNDING

          On the date of this Note, Borrower shall prepay interest due from 
          and including the date of this Note through and including the last 
          day of April, 1997.

     B)   MONTHLY PRINCIPAL AND INTEREST PAYMENTS

          On the first day of June 1997 and of each subsequent calendar month 
          through May 2007, Borrower shall pay an installment in the amount 
          of $56,402.15. Monthly installments of principal and interest shall 
          be made when due, regardless of the prior acceptance by the Lender 
          of unscheduled payments.

     C)   FINAL PAYMENT

          This Note shall mature on the first day of May, 2007 (the "Maturity 
          Date"), when the Borrower shall pay its entire principal balance, 
          together with all accrued interest and any other amounts owed by 
          the Borrower under this Note or under any of the other documents

                                      -1-



          enter into now or in the future in connection with the loan 
          evidenced by this Note (the "Loan Documents").

3.   BALLOON PAYMENT ACKNOWLEDGEMENT

     The Borrower acknowledges that the scheduled monthly installments 
     referred to in Subsection 2(B) will not amortize fully the principal sum 
     of this Note over its term, resulting in a "balloon" payment at 
     maturity. Any future agreement to extend the Note or refinance the 
     indebtedness it evidences may be made only by means of a writing 
     executed by a duly authorized officer of the Lender.

4.   APPLICATION OF MONTHLY PRINCIPAL AND INTEREST PAYMENTS

     When the Lender receives a monthly principal and interest payment, the 
     Lender shall apply it first to interest in arrears for the previous 
     month and then to the amortization of the principal amount of the Note, 
     unless other amounts are then due under the Note or the other Loan 
     Documents. If other amounts are due when a payment is received, the 
     Lender shall apply the payment first to accrued interest and then, at 
     its discretion, to either those other amounts or to principal.

5.   DEFAULT INTEREST

     If a Default exists (as defined in Section 8 below) the outstanding 
     principal balance of this Note shall, at the option of Lender, bear 
     interest at a rate (the "Default Rate") equal to the lesser of (i) 
     eighteen percent (18%) per annum and (ii) the maximum rate allowed by 
     law. If a court of competent jurisdiction determines that any interest 
     charged has exceeded the maximum rate allowed by law, the excess of the 
     amount collected over the legal rate of interest will be applied to the 
     indebtedness as a principal prepayment without premium, retroactively, 
     as of the date of receipt.

6.   LATE CHARGE

     Borrower shall pay a late charge equal to five percent (5%) of the 
     amount of each scheduled monthly principal and interest payment that is 
     not received by Lender on or before the tenth day of the calendar month 
     in which it is due. Late charges shall be paid on or before the tenth 
     day of the calendar month following the month during which they accrue. 
     Interest on unpaid late charges shall, at Lender's discretion, accrue at 
     the

                                      -2-



     Note Rate beginning on the first day of the calendar month following 
     their accrual.

7.   PREPAYMENT

     A.   This Note may be prepaid, in whole or in part, upon not less than 
     thirty (30) days' prior written notice to the Lender. At the time of any 
     prepayment, the Borrower shall pay all accrued interest on the principal 
     balance of the Note and all other sums due to the Lender under the Loan 
     Documents. In addition, unless the prepayment occurs during the 90-day 
     period preceding the Maturity Date, the Borrower shall pay a prepayment 
     premium equal to the greater of (a) one percent of the prepayment and 
     (b) an amount that the parties agree will compensate the Lender for the 
     loss of its bargained-for investment (the "Yield Protection Amount").

     B.   The Lender shall calculate the Yield Protection Amount as follows:

     C.   First, the Lender shall determine the annual percentage yield on 
     U.S. Treasury securities maturing at the end of the term of the loan 
     evidenced by this Note (the "Annual Treasury Instrument Yield"). The 
     Annual Treasury Instrument Yield shall be determined as of ten (10) 
     business days before the effective date of the prepayment. The Lender 
     shall base its determination of the Annual Treasury Instrument Yield on 
     the yield on U.S. Treasury Instruments, as published in THE WALL STREET 
     JOURNAL (or, if THE WALL STREET JOURNAL is not then being published or 
     if no such reports are then being published in THE WALL STREET JOURNAL, 
     as reported in another public source of information nationally 
     recognized for accuracy in the reporting of the trading of governmental 
     securities). If no such instruments mature on the exact maturity date of 
     the Note, the Lender shall interpolate the Annual Treasury Instrument 
     Yield on a straight-line basis using the yield on the instrument whose 
     maturity date most closely precedes that of the Note and the yield on 
     the instrument whose maturity date most closely succeeds that of the 
     Note.

     D.   Second, the Lender shall determine the hypothetical monthly 
     interest-only payment (based on a 360-day year and 30-day months) which 
     would be payable on a promissory note having a principal balance equal 
     to the prepaid amount and bearing interest at the "bond-equivalent" rate 
     which would produce a yield equal to the Annual Treasury Instrument 
     Yield (the "Monthly Reinvestment Payment").

     E.   Third, the Lender shall determine the hypothetical monthly 
     interest-only payment (based on a 360-day year and 30-day months) which 
     would be payable on a promissory note having a principal balance equal 
     to the prepaid amount and bearing interest at the Note Rate (the 
     "Monthly Coupon Rate Payment").

                                      -3-



     F.   Fourth, the Lender shall determine the present value of a series of 
     monthly payments, each equal in amount to the amount by which the 
     Monthly Coupon Rate Payment exceeds the Monthly Reinvestment Payment, 
     received on the first day of each calendar month from and including the 
     first day of the first full calendar month immediately following the 
     effective date of prepayment to and including the Maturity Date, using 
     the Annual Treasury Instrument Yield as the discount rate.

     G.   The present value of that series of payments is the "Yield 
     Protection Amount."

8.   DEFAULT

     A default on this Note ("Default") shall exist if (a) the Lender fails 
     to receive any required installment of principal and interest on or 
     before the tenth day of the calendar month in which it is due, (b) the 
     Borrower fails to pay the matured balance of the Note on the Maturity 
     Date or (c) a "Default" exists as defined in any other Loan Document.

9.   ACCELERATION

     If a Default exists, the Lender may, at its option, without notice to 
     Borrower, declare the unpaid principal balance of this Note to be 
     immediately due and payable, together with all accrued interest on the 
     indebtedness and all other charges due and payable by Borrower under any 
     other Loan Document.

10.  PREPAYMENT FOLLOWING ACCELERATION

     Any Default resulting in the acceleration of the indebtedness shall be 
     presumed to be an attempt to avoid the provisions of Section 7 of this 
     Note, which prohibit prepayment on condition the Lender's obligation to 
     accept prepayment on the payment of a prepayment premium. Accordingly, 
     if the indebtedness is accelerated, any amounts tendered to repay the 
     accelerated indebtedness, or realized by the Lender through its remedies 
     following acceleration, shall be subject to the prepayment premium 
     required under Section 7.

11.  SECURITY

     This Note is secured by a Mortgage and Security Agreement (the 
     "Mortgage") granted by Borrower to the Lender, encumbering certain real 
     property located in the Essex County, New Jersey and granting a security 
     interest in certain fixtures and personal property, and by an Absolute

                                      -4-



     Assignment of Leases and Rents made by Borrower to Lender, assigning the 
     landlord's interest in all present and future leases of all or any 
     portion of the real property encumbered by the Mortgage. Reference is 
     made to the Loan Documents for a description of the security and rights 
     of the Lender. This reference shall not affect the absolute and 
     unconditional obligation of the Borrower to pay the indebtedness 
     evidenced by this Note in accordance with its terms.

12.  RECOURSE TO BORROWER

     Borrower shall have no personal liability for, and the Lender shall have 
     no recourse to any property of Borrower other than the property 
     subjected to the liens or security interests of any of the Loan 
     Documents (the "Property"), in the event of Default by Borrower in 
     performing its obligations under this Note or any other Loan Document; 
     PROVIDED, HOWEVER, that Borrower shall be personally liable for, and 
     shall defend the Lender and hold Lender harmless from and against any 
     and all Lender's costs, expenses (including reasonable attorneys' fees), 
     losses and actual damages caused by, or incurred in connection with, (i) 
     waste, not including ordinary wear and tear, unless Borrower fails to 
     maintain the real property securing the Note (the "Real Property") with 
     ordinary care; (ii) fraud or written material misrepresentation; (iii) 
     failure to pay taxes, assessments, ground rent or any other lienable 
     impositions as required under the Loan Documents; (iv) misapplication of 
     tenant security deposits, insurance proceeds or condemnation proceeds, 
     or the unavailability to the Lender of condemnation proceeds because a 
     lease of the Real Property grants a tenant the right to a portion of the 
     award for the estate taken (unless that portion is specifically awarded 
     to the tenant or allocated to the tenant's interest by the condemning 
     authority); (v) failure while in monetary default to pay to Lender all 
     rents, income and profits, while in monetary default to pay to Lender 
     all rents, income and profits, net or reasonable and customary operating 
     expenses; (vi) failure to perform under the environmental covenants or 
     indemnifications set forth in the Loan Documents; (vii) destruction or 
     removal from the Real Property of fixtures or personal property securing 
     the Loan, unless replaced by items of equal value; (viii) terminating, 
     amending or entering into a lease of the Real Property in violation of 
     the Loan Documents; or (ix) wilful or grossly negligent violation of 
     applicable law. The Borrower may also assume recourse liability under 
     Loan Documents or other agreements that expressly provide for such 
     personal liability, and such Loan Documents or agreements, if any, shall 
     not be subject to the exculpation from personal liability set forth in 
     this Paragraph.

     In addition, the Borrower shall have personal liability for the entire 
     indebtedness if the Borrower (a) voluntarily transfers or encumbers the 
     Property in violation of the Loan Documents, or (b) files a voluntary

                                      -5-



     petition for reorganization under the Bankruptcy Code and has not 
     offered, prior to the filing, to enter into the Lender's choice of 
     either an agreement to permit an uncontested foreclosure or an agreement 
     to deliver a deed in lieu of foreclosure, within sixty days of Lender's 
     acceptance of the offer. Following Lender's acceptance of such an 
     offer, default by the Borrower shall trigger personal liability for the 
     entire indebtedness. No such offer shall be conditioned on any payment 
     by the Lender, on the release of any obligor from any recourse 
     obligation, or on any other concession.

13.  SEVERABILITY

     If any provision of this Note is held to be invalid, illegal or 
     unenforceable in any respect, or operates, or would if enforced operate 
     to invalidate this Note, then that provision shall be deemed null and 
     void. Nevertheless, its nullity shall not affect the remaining 
     provisions of this Note, which shall in no way be affected, prejudiced 
     or disturbed.

14.  WAIVER

     A.   The Borrower waives demand, presentment for payment, protest, 
     notice of protest, dishonor and of nonpayment and any and all lack of 
     diligence or delays in collection or enforcement of this Note. Without 
     affecting the liability of Borrower under this Note, the Lender may 
     release any of the Property, grant any indulgence, forbearance or 
     extension of time for payment, or release any other person now or in the 
     future liable for the payment or performance of any obligation under 
     this Note or any of the Loan Documents.

     B.   Borrower (i) waives any homestead of similar exemption; (ii) waives 
     any statute of limitation; (iii) agrees that the Lender may, without 
     impairing any future right to insist on strict and timely compliance 
     with the terms of this Note, grant any number of extensions of time for 
     the scheduled payments of any amounts due, and may make any other 
     accommodation with respect to the indebtedness; (iv) waives any right to 
     require a marshalling of assets; and (v) to the extent not prohibited by 
     applicable law, waives the benefit of any law or rule of law intended 
     for its advantage or protection as a debtor or providing for its release 
     or discharge from liability under this Note, excepting only the defense 
     of full and complete payment of all amounts due under this Note and the 
     Loan Documents.

                                    -6-


15.  VARIATION IN PRONOUNS

     All the terms and words used in this Note, regardless of the number and 
     gender in which they are used, shall be deemed and construed to include 
     any other number, singular or plural, and any other gender, masculine, 
     feminine, or neuter, as the context or sense of this Note or any 
     paragraph or clause herein may require, the same as if such word had 
     been fully and properly written in the correct number and gender.

16.  WAIVER OF JURY TRIAL

     THE BORROWER AND LENDER WAIVE ANY RIGHT TO A TRIAL BY JURY IN ANY ACTION 
     OR PROCEEDING TO ENFORCE OR DEFEND ANY RIGHTS (A) UNDER THIS NOTE OR ANY 
     OTHER LOAN DOCUMENT OR (B) ARISING FROM ANY LENDING RELATIONSHIP 
     EXISTING IN CONNECTION WITH THIS NOTE OR ANY OTHER LOAN DOCUMENT, AND 
     THE BORROWER AND LENDER AGREE THAT ANY SUCH ACTION OR PROCEEDING SHALL 
     BE TRIED BEFORE A JUDGE AND NOT BEFORE A JURY.

17.  OFFSET RIGHTS

     In addition to all liens upon and rights of setoff against the money, 
     securities, or other property of the Borrower given to the Lender by 
     law, the Lender shall have a lien upon and a right of setoff against all 
     money, securities, and other property of the Borrower, now or hereafter 
     in possession of or on deposit with Lender, whether held in a general or 
     special account or deposit, or safe-keeping or otherwise, and every such 
     lien and right of setoff may be exercised without demand upon, or 
     notice to the Borrower. No lien or right of setoff shall be deemed to 
     have been waived by any act or conduct on the part of the Lender, or by 
     any neglect to exercise such right of setoff or to enforce such lien, or 
     by any delay in so doing, and every right of setoff and lien shall 
     continue in full force and effect until such right of setoff or lien is 
     specifically waived or released by an instrument in writing executed by 
     the Lender.

18.  COMMERCIAL LOAN

     The Borrower hereby represents and warrants to the Lender that the Loan 
     was made for commercial or business purposes, and that the funds 
     evidenced by this Note will be used solely in connection with such 
     purposes.

                                    -7-


19.  GOVERNING LAW

     This Note shall be construed and enforced according to, and governed by, 
     the laws of New Jersey without reference to conflicts of laws provisions 
     which, but for this provision, would require the application of the law 
     of any other jurisdiction.

20.  TIME OF ESSENCE

     In the performance of the Borrower's obligations under this Note, time 
     is of the essence.
