See accompanying notes. 6 FORM 10-Q PART 1 ITEM 1 PAGE 4 VICOR CORPORATION Notes to Condensed Consolidated Financial Statements June 30, 1997 (Unaudited) 1. BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and pursuant to the rules and regulations of the Securities and Exchange Commission. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments (consisting of only normal recurring adjustments) considered necessary for a fair presentation have been included. Operating results for the three- and six-month periods ended June 30, 1997 are not necessarily indicative of the results that may be expected for the year ended December 31, 1997. For further information, refer to the consolidated financial statements and notes thereto included in the Company's audited financial statements for the year ended December 31, 1996, contained in the Company's annual report filed on Form 10-K (File #0-18277) with the Securities and Exchange Commission. 2. NET INCOME PER SHARE Net income per common share is based on the weighted average number of shares of common shares and common share equivalents. In February 1997, the Financial Accounting Standards Board issued Statement No. 128, "Earnings per Share," which is effective for the Company on December 31, 1997. At that time, the Company will be required to change the method currently used to compute earnings per share and to restate all prior periods. Under the new requirements for calculating primary earnings per share, the dilutive effect of stock options will be excluded. There is not expected to be any material change to either primary or fully diluted net income per share for the quarters or the six months ended June 30, 1997 and 1996 as a result of the new method. 3. INVENTORIES Inventories are valued at the lower of cost (determined using the first-in, first-out method) or market. Costs associated with the long-term contract for the sale of automated manufacturing line equipment are included in inventories reduced by amounts identified with revenues recognized under the contract. Inventories were as follows as of June 30, 1997 and December 31, 1996 (in thousands):
June 30, 1997 December 31, 1996 ------------- ----------------- Raw materials ................. $12,682 $12,627 Work-in-process ............... 3,179 2,290 Finished goods ................ 3,915 6,212 Unbilled costs ................ 1 - ------- ------- $19,777 $21,129 ======= =======
7 FORM 10-Q PART I ITEM 2 PAGE 5 VICOR CORPORATION Notes to Condensed Consolidated Financial Statements June 30, 1997 (Continued) 4. MORTGAGE NOTE RECEIVABLE In May 1997, the Company received a promissory note in the amount of $7,500,000 from an unrelated third party in exchange for $5,000,000 in cash plus the termination of an existing note in the amount of $2,500,000. The note bears interest at 9% and is due in May 2002. The note is secured by a mortgage on certain real estate and by the assignment of certain leases and other contracts. 5. IMPACT OF RECENTLY ISSUED ACCOUNTING STANDARDS In June 1997, the FASB issued Statement No. 130, "Reporting Comprehensive Income," and Statement No. 131, "Disclosures About Segments of an Enterprise and Related Information." Statement No. 130 establishes standards for the reporting and display of comprehensive income and its components. Statement No. 131 establishes standards for the way that public companies report information about operating segments in financial statements. This Statement supersedes Statement No. 14, "Financial Reporting for Segments of a Business Enterprise," but retains the requirements to report information about major customers. Statements 130 and 131 are effective for the Company in fiscal 1998. The Company does not believe that the adoption of these Statements will have a material effect on the Company's financial statements. 8 FORM 10-Q PART I ITEM 2 PAGE 6 VICOR CORPORATION Management's Discussion and Analysis of Financial Condition and Results of Operations June 30, 1997 Except for historical information contained herein, some matters discussed in this report constitute forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Actual results could differ materially from those projected in the forward-looking statements as a result of the risk factors set forth in this report and in the Company's Annual Report on Form 10-K for the year ended December 31, 1996. Reference is made in particular to the discussions set forth below in this Report under "Management's Discussion and Analysis of Financial Condition and Results of Operations," and set forth in the Annual Report on Form 10-K under Item 1 -- "Business -- Next-Generation Automated Manufacturing Line," "--Competition," "--Patents," and "--Licensing," and under Item 7 -- "Management's Discussion and Analysis of Financial Condition and Results of Operations." Results of Operations - --------------------- Three months ended June 30, 1997, compared to three months ended June 30, 1996 - ------------------------------------------------------------------------------ Net revenues for the second quarter of 1997 were $39,718,000, an increase of $3,016,000 (8.2%) as compared to $36,702,000 for the same period a year ago. The increase in net revenues was primarily due to an increase of unit shipments of standard and custom products of approximately $4,400,000, offset by a reduction in license income of approximately $1,100,000. Gross margin increased $569,000 (2.9%) to $20,416,000 from $19,847,000, but decreased as a percentage of net revenues from 54.1% to 51.4%. The primary components of the increase in gross margin were changes in the revenue mix. Selling, general and administrative expenses were $7,483,000 for the period, an increase of $711,000 (10.5%) over the same period in 1996. As a percentage of net revenues, selling, general and administrative expenses increased to 18.8% compared to 18.5% in 1996. The principal components of the $711,000 increase were $470,000 (19.3%) of increased compensation expense due to growth in staffing levels of selling and administrative personnel; $142,000 (125.1%) of increased legal expenses; $84,000 (10.0%) of increased advertising expenses; and $84,000 (8.0%) of increased sales commission expense. Research and development expenses increased $915,000 (27.7%) to $4,221,000 and increased as a percentage of net revenues to 10.6% from 9.0%. The principal components of the $915,000 increase were $484,000 (25.0%) of increased compensation expense due to growth in staffing levels of engineering personnel and $148,000 (30.7%) of increased project material costs. The Company continues work on its next-generation products. The Company does not expect revenues or earnings from this new product family to be material over the next several quarters. See also the discussion under "Liquidity and Capital Resources." Other income increased $337,000 (37.7%) from the same period a year ago, to $1,230,000. Other income is primarily comprised of interest income derived from cash and cash equivalents, short-term investments, and notes receivable associated with the Company's real estate transactions in Andover, Massachusetts. Interest income increased primarily due to an increase in cash balances earning interest. Income before income taxes was $9,942,000, a decrease of $720,000 (6.8%) compared to the same period in 1996. As a percentage of net revenues, income before income taxes decreased from 29.1% to 25.0% primarily due to the increase in operating expenses as discussed above. Net income per share for the second quarter of 1997 was $.15, compared to $.16 for the second quarter of 1996, a decrease of $.01 (6.3%). 9 FORM 10-Q PART I ITEM 2 PAGE 7 VICOR CORPORATION Management's Discussion and Analysis of Financial Condition and Results of Operations June 30, 1997 (continued) Six months ended June 30, 1997, compared to six months ended June 30, 1996 - -------------------------------------------------------------------------- Net revenues for the first six months of 1997 were $77,657,000, an increase of $5,149,000 (7.1%) as compared to $72,508,000 for the same period a year ago. The increase in net revenues was primarily due to an increase of unit shipments of standard and custom products of approximately $5,800,000, offset by a reduction in license income of approximately $1,100,000. Gross margin increased $1,372,000 (3.5%) to $40,478,000 from $39,106,000, but decreased as a percentage of net revenues from 53.9% to 52.1%. The primary components of the increase in gross margin were changes in the revenue mix. Selling, general and administrative expenses were $14,930,000 for the period, an increase of $1,923,000 (14.8%) over the same period in 1996. As a percentage of net revenues, selling, general and administrative expenses increased to 19.2% compared to 17.9% in 1996. The principal components of the $1,923,000 increase were $1,064,000 (22.8%) of compensation expense due to growth in staffing levels of selling and administrative personnel; $401,000 (27.0%) of increased advertising expenses; $184,000 (48.6%) of increased legal expenses; and $139,000 (6.8%) of increased sales commission expense. Research and development expenses increased $1,852,000 (27.4%) to $8,600,000 and increased as a percentage of net revenues to 11.1% from 9.3%. The principal components of the $1,852,000 increase were $1,036,000 (27.2%) of compensation expense due to growth in staffing levels of engineering personnel and $264,000 (22.7%) of increased project material costs. Other income increased $449,000 (23.8%) to $2,332,000. Other income is primarily comprised of interest income derived from cash and cash equivalents, short-term investments, and notes receivable associated with the Company's real estate transactions in Andover, Massachusetts. Interest income increased primarily due to an increase in cash balances earning interest. Income before income taxes was $19,280,000, a decrease of $1,954,000 (9.2%) compared to the same period in 1996. As a percentage of net revenues, income before income taxes decreased from 29.3% to 24.8% primarily due to the increase in operating expenses as discussed above. Net income per share for the first six months of 1997 was $.29, compared to $.32 for the first six months of 1996, a decrease of $.03 (9.4%). Liquidity and Capital Resources - ------------------------------- At June 30, 1997 the Company had $80,843,000 in cash and cash equivalents. The ratio of current assets to current liabilities was 8.2:1 compared to 8.8:1 at December 31, 1996. Working capital increased $8,898,000, from $108,551,000 at December 31, 1996 to $117,449,000 at June 30, 1997. The primary factor affecting the working capital increase was an increase in cash of $7,196,000 during the first six months of 1997. The increase in cash was primarily attributable to cash derived from operating activities of $14,882,000; the net proceeds from the issuance of Common Stock upon the exercise of stock options, and the related income tax benefit derived from such issuance, of $6,308,000. The primary uses of cash for the first six months of 1997 were for additions to property and equipment of $8,406,000 and for increased notes receivable of $5,215,000. See the discussion under "Notes to Condensed Consolidated Financial Statements," Item 4--"Mortgage Note Receivable." 10 FORM 10-Q PART I ITEM 2 PAGE 8 VICOR CORPORATION Management's Discussion and Analysis of Financial Condition and Results of Operations June 30, 1997 (continued) The Company plans to make continuing investments in manufacturing equipment, much of which is built internally. The internal construction of manufacturing machinery is a practice which the Company expects to follow over the next several years. In 1995, the Company announced that it had started prototype production on a new automated manufacturing line specifically designed to manufacture next-generation products. In the fourth quarter of 1996, the Company began introducing selected models of its next-generation product families. While management believes that the initiation of limited production on the new manufacturing line and the introduction of selected models of its next-generation product families are important milestones, there can be no assurance that problems will not substantially delay the ultimate general introduction of the complete product line, require modification of product specifications, or prevent attainment of the anticipated capacity of the new manufacturing line. Significant revenues from the sale of any products in the Company's next-generation product line are not expected to occur for several quarters. In February, 1996, the Board of Directors of the Company authorized the repurchase of the Company's Common Stock up to an aggregate amount of approximately $19,500,000, including amounts remaining under a prior authorization. The plan authorized the Company to make such repurchases from time to time in the open market or through privately negotiated transactions. The timing of this program and the amount of the stock that may be repurchased is at the discretion of management based on its view of economic and financial market conditions. There were no repurchases in the six months ended June 30, 1997. The Company has an unused line of credit with a bank under which the Company may borrow up to $4,000,000 on a revolving credit basis. The Company believes that cash generated from operations and the total of its cash and cash equivalents, together with other sources of liquidity, will be sufficient to fund planned operations and capital equipment purchases for the foreseeable future. At June 30, 1997, the Company had approximately $700,000 of capital expenditure commitments. The Company does not consider the impact of inflation on its business activities to have been significant to date. 11 FORM 10-Q PART II ITEM 1-6 PAGE 9 VICOR CORPORATION Part II - Other Information June 30, 1997 Item 1 - Legal Proceedings - -------------------------- The Company is involved in certain litigation incidental to the conduct of its business. While the outcome of lawsuits against the Company cannot be predicted with certainty, management does not expect any current litigation to have a material adverse impact on the Company.

$7,500,000.00                                                  May 29, 1997

         FOR VALUE RECEIVED, WILLIAM J. CALLAHAN and WILLIAM J. CALLAHAN, JR.,
Trustees of ANDOVER PARK REALTY TRUST, u/d/t dated June 25, 1986 and recorded
with the Essex County (North District) Registry of Deeds in Book 2226, Page 284
(the "Borrower") having a mailing address of P. O. Box 269, Bedford, MA 01730,
promise to pay to the order of VICOR CORPORATION, a Delaware corporation
(together with any successor holder or holders of this Note, the "Lender") at
its office at 23 Frontage Road, Andover, MA 01810, or such other place as Lender
may designate, the principal sum of Seven Million Five Hundred Thousand
($7,500,000.00) Dollars, or so much thereof as shall be advanced hereunder,
together with interest thereon, as hereinafter set forth.

         Interest on the principal balance of this Note from time to time
outstanding shall accrue from the date hereof at a monthly rate of nine (9%)
percent. Interest only shall be payable monthly, in arrears, on the first day of
each month, in each calendar year. Interest shall be computed on the basis of a
three hundred sixty (360) day year and shall be paid for the actual number of
days on which principal is outstanding.

         In any event, the entire outstanding principal balance of this Note,
together with any accrued interest and other charges as may be due hereunder,
shall be paid on May 29, 2002 (the "Maturity Date").

         In the event that any regularly scheduled payment of interest due
hereunder is not paid within ten (10) days after the date it is due, the Lender
shall have the right, in addition to any other rights hereunder, to collect a
late charge as compensation for increased costs of administering such late
payment. Such late charge shall be in an amount equal to three (3%) percent of
the amount of such late payment, and shall be due and payable upon demand.

         In the event that any payment due hereunder is not paid within ten (10)
days after the date it is due or upon a default under the mortgage securing this
Note (the "Mortgage") or under any other instrument executed by the Borrower in
connection with the loan evidenced by this Note (together with this Note and the
Mortgage, the "Loan Documents") which default is not cured within the applicable
grace period, if any, the Lender at its option, may declare immediately due and
payable the entire outstanding balance of principal and interest, together with
all other charges to which the Lender may be entitled. If this Note is so
accelerated or any amounts due hereunder are not paid on the Maturity Date, all
amounts due hereunder shall, after such acceleration or such Maturity Date, as
the case may be, bear interest at a rate which shall equal the Prime Rate, plus
five (5) percentage points, until paid.

         The outstanding balance of principal due hereunder may be prepaid in
full, but not in part, without penalty, only after the expiration of twenty-four
(24) months from the date of this Note and the sale of the premises described in
the Mortgage. The Lender may at its sole and exclusive option require a
prepayment of One Million Five Hundred Thousand ($1,500,000) Dollars from the
Borrower upon the sale or transfer of Lot 6A Federal Street, Woodland Park,
Andover, Massachusetts as set forth in the Loan Documents, such payment, if
required, shall be made without penalty during the Term or the Extended Term
(hereinafter defined) of this Note.

         In the event the Borrower has not defaulted under the Loan Documents,
at the option of the Borrower, the term of this Note may be extended for an
additional twenty-four (24) months (the "Extended Term") by written notice
delivered to the Lender after January 1, 2002 and prior to February 15, 2002.
The annual rate of interest payable under this Note during the Extended Term
shall be calculated on May 29, 2002 at the greater of eleven (11%) percent or
the Prime Rate, plus two (2%) percent.

         As used herein, the term Prime Rate shall mean the rate of interest (or
the higher of a range of rates) announced or published by The Wall Street
Journal from time to time as the Prime Rate as determined based upon corporate
loans on at least 75% of the nation's largest banks. In the event the Prime Rate
is no longer published or announced or becomes unascertainable for any reason,
the Lender shall designate a comparable reference rate which shall be deemed the
Prime Rate hereunder.


   2


         Any notice required or permitted to be delivered hereunder shall be in
writing and shall be deemed to be delivered on the earlier of (i) the date
received, or (ii) the date of delivery, refusal, or non-delivery indicated on
the return receipt, if deposited in a United States Postal Service depository,
postage prepaid, sent registered or certified mail, return receipt requested,
addressed to the party to receive the same at the address of such party set
forth at the beginning of this Note, or at such other address as may be designed
in a notice delivered or mailed as herein provided.

         The obligations of Borrower hereunder, if more than one, shall be joint
and several.

         The Lender agrees that except as otherwise provided in any Guaranty of
this Note or the Loan Documents, it shall proceed only against the premises
described in the Mortgage and other collateral given to secure this Note and
that neither Borrower nor any trustee or beneficiary of Borrower shall be
personally liable for any amounts due hereunder or under the other Loan
Documents for any deficiency which may arise upon a foreclosure of the Mortgage
or the liquidation of other collateral given to secure this Note; provided that
this provision shall not diminish in any way the powers of the Lender to
foreclose the Mortgage and to exercise its other rights under the Loan Documents
and at law in the event of a default; and provided further that the Borrower and
the Borrower's trustees and beneficiaries shall be personally liable to the
Lender to the same extent as they would have been liable absent the foregoing
(a) for fraud or willful misrepresentation, or (b) for the retention of any
rental or other sums with respect to the premises described in the Mortgage, net
of operating and tax expenses actually paid to third parties, which are received
at any time after the earlier of (i) the acceleration of this Note, (ii) a
default by the Borrower under any of the Loan Documents which is not cured
within the applicable grace period, or (iii) if notice of default is required
under the Loan Documents, the date such notice is deemed to be delivered to
Borrower, or (c) if the Borrower or any successor entity files a petition for
reorganization or liquidation or for protection from creditors under the United
States Bankruptcy Code or any similar state law.

         The Borrower agrees to pay all charges (including reasonable attorney's
fees) of Lender in connection with the collection and/or enforcement of this
Note or any other Loan Document or in protecting or preserving the security for
this Note, including without limitation, any costs incurred in connection with
pursuing its rights in any bankruptcy proceeding affecting the Borrower, whether
or not suit is brought against the Borrower.

         The failure of the Lender at any time to exercise any option or right
hereunder shall not constitute a waiver of the Lender's right to exercise such
option or right at any other time.

         The Borrower and all endorsers and guarantors of this Note hereby
jointly and severally waive presentment, demand, notice, protest and all other
suretyship defenses generally and agree that (i) any renewal, extension or
postponement of the time of payment or any other indulgence, (ii) any
modification, supplement or alteration of any of the Borrower's obligations
undertaken in connection with this Note or any of the other Loan Documents, or
(iii) any substitution, exchange or release of collateral or the addition or
release of any person or entity primarily or secondarily liable, may be effected
without notice to the Borrower or any endorser or guarantor of the Borrower's
obligations, and without releasing the Borrower or such endorser or guarantor
from any liability hereunder.

         The Borrower and all endorsers and guarantors of this Note hereby
jointly and severally agree that this Note constitutes a written consent to
waiver of trial by jury. The Borrower and all endorsers and guarantors of this
Note hereby jointly and severally authorize and empower the Lender in the name,
place and stead of the Borrower and any endorser or guarantor, to file this Note
with the clerk or judge of any court of competent jurisdiction as a statutory
written consent to waiver of trial by jury.

         This Note shall be governed by, construed, and enforced in accordance
with the laws of The Commonwealth of Massachusetts. If any provision of this
Note is held to be invalid or unenforceable by a court of competent
jurisdiction, the other provisions of this Note shall remain in full force and
effect. If the payment of any interest due hereunder would subject the Lender to
any penalty under applicable law, then the payments due hereunder shall be
automatically reduced to what they would be at the highest rate authorized under
applicable law.

3.       HAZARDOUS SUBSTANCES.

         (a) The Mortgagor represents and warrants that except as customarily
and lawfully used in connection with the construction and operation of the
Mortgaged Property, it has never generated, stored or disposed of any hazardous
substances, as defined herein, on the Mortgaged Property; that the Mortgagor is
not aware of the generation, storage, disposal or release of such substances on
the Mortgaged Property by anyone else; and that the Mortgagor is not aware of
the generation, storage, disposal or release of such substances upon or into the
real property adjoining or in the vicinity of the Mortgaged Property which
through soil or groundwater migration could have come to be located at the
Mortgaged Property. For the purposes of this Mortgage and the other Loan
Documents, "hazardous substances" shall mean "oil" and "hazardous materials" as
defined in M.G.L., Ch. 21E and "hazardous substances" as defined in the
Comprehensive Environmental Response Compensation and Liability Act of l980, 42
U.S.C., Section 9601, ET SEQ., as amended by the Superfund Amendments and
Reauthorization Act of 1986, Pub. L. No. 99-499, 100 Stat. 1613, and as
otherwise amended ("CERCLA"), and regulations adopted pursuant to such Acts or
in any Hazardous Materials Laws, as hereinafter defined. The Mortgagor agrees
not to release or dispose of any hazardous substances at the Mortgaged Property,
nor to permit the same, at any time.

         (b) The Mortgagor represents and warrants that to the best of
Mortgagor's knowledge the Mortgaged Property currently complies and that the
Mortgaged Property and the Mortgagor shall comply with all federal, state and
local laws and regulations, including but not limited to M.G.L., Ch. 21E, CERCLA
and the Resource Conservation and Recovery Act of 1976, 42 U.S.C.,
ss.ss.6901-6987, as each may be amended from time to time, and regulations
promulgated pursuant to such Acts (such Acts and other similar laws and
regulations are collectively referred to as the "Hazardous Materials Laws")
relating to the storage, use, disposal, generation, transportation, or treatment
of hazardous, toxic or radioactive matter, including but not limited to
hazardous substances. The Mortgagor covenants to strictly comply with the
requirements of all Hazardous Materials Laws and to immediately notify the
Mortgagee of the presence, "release" or "threat of release" (as those terms are
defined in M.G.L., Ch. 21E) of any hazardous substances at or from the Mortgaged
Property or of any notice or claim received by it of any violation of any
Hazardous Materials Laws.

         (c) To the fullest extent permissible according to law, and without
limiting any other rights or remedies of the Mortgagee, the Mortgagor
unconditionally, absolutely and irrevocably agrees to defend, hold harmless and
indemnify the Mortgagee and its officers, employees, agents and contractors
against all damages (including consequential damages), claims, costs, losses,
liabilities and expenses, including attorneys' fees and expenses, suffered or
incurred by the Mortgagee due to the existence at any time of any hazardous
substances at the Mortgaged Property or at any other property owned, occupied or
operated by the Mortgagor or by any other person for whose conduct the Mortgagor
is responsible, other than such claims, costs, liabilities and expenses arising
out of the intentional acts or negligence of the Mortgagee, its agents,
employees and independent contractors, including without limitation, any such
claims, costs, losses, liabilities and expenses arising from the violation of
any Hazardous Materials Laws or the imposition by any local, state or federal
government or governmental agency, department or authority, of a lien,
attachment or other encumbrance on any part of the Mortgaged Property or any
other property then owned by the Mortgagor. The foregoing indemnification shall
survive the satisfaction of the Mortgagor's obligations under the Loan Documents
and the release, foreclosure or assignment of this Mortgage. In addition, the
Mortgagee may (but shall not be obligated to), from time to time at the
Mortgagee's expense, conduct such investigations as the Mortgagee deems
reasonable to determine whether hazardous substances exist on any 


   3


part of the Mortgaged Property and to determine the source, quantity and type of
such hazardous substances, if any, and the Mortgagor shall cooperate with the
Mortgagee in conducting such investigations. Such investigations may include
without limitation a detailed visual inspection of the Mortgaged Property,
including all storage areas, storage tanks, drains and dry wells, as well as the
taking of soil samples, surface water samples, and ground water samples and such
other investigations or analyses as are necessary or appropriate in the
Mortgagee's sole discretion for a complete assessment of the compliance of the
Mortgaged Property and the use and operation thereof with all of the Mortgaged
Property and the use and operation thereof with all Hazardous Materials Laws.
The Mortgagee and its officers, employees, agents and contractors shall have and
are hereby granted the right to enter upon the Mortgaged Property for the
foregoing purposes.

         (d) If the presence or release of hazardous substances at or from the
Mortgaged Property has resulted in contamination or determination of any portion
of the Mortgaged Property or any other affected property resulting in a level of
contamination greater than the levels permitted or established by any
governmental agency having jurisdiction, then the Mortgagor shall promptly take
any and all action necessary to clean up such contamination to the extent
required by any governmental authority having jurisdiction or as a condition to
the issuance or continuing effectiveness of any governmental approval or any
insurance policy that relates to the Mortgaged Property or the use thereof. The
Mortgagor shall further be solely responsible for, and shall defend, indemnify
and hold the Mortgagee and its officers, employees, agents and contractors
harmless from and against all damages (including consequential damages), claims,
costs, losses, liabilities and expenses, including attorneys' fees and expenses,
of whatever nature, on account of, arising out of or in connection with any
removal, cleanup and restoration work required to return the Mortgaged Property
and any other affected property of whatever nature to their conditions existing
prior to the presence or release of the hazardous substances; provided, however,
that the foregoing indemnity shall not apply if the presence or release of
hazardous substances is caused by the Mortgagee, its agents, employees and
independent contractors.

         (e) Without limiting the generality of the foregoing, the Mortgagor,
and the Mortgaged Property and all alterations thereof, shall comply with all
local, state and federal laws and regulations now or hereafter in effect and
applicable relating to the presence, abatement, removal, disposal,
transportation or treatment of materials containing asbestos. To the fullest
extent permissible according to law, and without limiting any other rights or
remedies of the Mortgagee, the Mortgagor unconditionally, absolutely and
irrevocably agrees to defend, hold harmless and indemnify the Mortgagee and each
of its officers, employees, agents and contractors against all damages
(including consequential damages), claims, costs, losses, liabilities and
expenses, including attorneys' fees and expenses, suffered or incurred by the
Mortgagee on account of the existence at the Mortgaged Property of any materials
containing asbestos at any time, including without limitation, any such claims,
costs, losses, liabilities and expenses arising from the violation of any laws
relating thereto. The foregoing indemnification shall survive satisfaction of
the Mortgagor's obligations under the Loan Documents and the release,
foreclosure or assignment of this Mortgage. In addition, the Mortgagee may (but
shall not be obligated to), from time to time at the Mortgagor's expense,
conduct such investigations as the Mortgagee deems reasonable to determine
whether asbestos or materials containing asbestos are being released in to the
environment at the Mortgaged Property, and the Mortgagor shall cooperate with
the Mortgagee in conducting such investigations. The Mortgagee and its officers,
employees, agents and contractors shall have and are hereby granted the right to
enter upon the Mortgaged Property for the foregoing purposes.

4.       TAXES AND ASSESSMENTS. The Mortgagor shall pay or cause to be paid, not
later than the last day upon which payment may be made without penalty or
interest, all taxes, charges for water, sewer and other municipal services and
assessments and any other charges or assessments that might become a lien prior
to the lien of this Mortgage, whether or not assessed against the Mortgagor or
the Mortgagee, and whether or not assessed pursuant to authority adopted before
or after the date of this Mortgage if applicable or related in any way to the
Mortgaged Property, any interest in the Mortgaged Property of the Mortgagor or
the Mortgagee or the debt, obligations or performance secured hereby, or the
disbursement or application of the proceeds therefrom (collectively, the
"Impositions"), excluding, however, any income or corporation excise tax of the
Mortgagee. If at any time the Mortgagee does not require the escrow of payments
for Impositions, the Mortgagor shall furnish to the Mortgagee receipted real
estate tax bills for the Mortgaged Property not later than ten (10) days after
the date from which any interest or penalty would accrue for nonpayment thereof.
The Mortgagor shall also furnish to the Mortgagee 

   4


evidence of payment of all other Impositions within fifteen (15) days after
written request therefor by the Mortgagee. If the Mortgagor is not permitted by
applicable law to pay any Imposition or the payment of such Imposition would
violate any usury law applicable to the transaction contemplated by this
Mortgage, at the option of the Mortgagee, the principal sum secured by this
Mortgage shall become due and payable upon the date specified by written notice
given by the Mortgagee to the Mortgagor, which date shall be at least thirty
days after the date of such notice. The Mortgagor shall require all tenants of
the Mortgaged Property to pay, when due, all taxes assessed against personal
property and trade fixtures of each said tenant.

         If requested by the Mortgagee, after an Event of Default (as herein
defined), the Mortgagor shall pay to the Mortgagee monthly, on the first day of
each month, a sum reasonably determined by the Mortgagee to be sufficient to
provide in the aggregate a fund adequate to pay each Imposition at least thirty
(30) days before it becomes delinquent, and, in addition, shall pay to the
Mortgagee on demand any balance necessary to pay in full each Imposition at
least thirty (30) days before the date on which it becomes due and payable. Such
sums shall not bear interest and may be commingled with the general assets of
the Mortgagee. The Mortgagee shall not be required to account for any profits
resulting from its use thereof. Such sums may be applied by the Mortgagee to the
payment of the Impositions or any other obligation of the Mortgagor hereunder.
The Mortgagor shall furnish to the Mortgagee all original bills relating to any
Imposition promptly upon issuance.

         The Mortgagor shall have the right, after giving written notice to the
Mortgagee and subject to the conditions stated below, to contest by appropriate
legal proceedings the amount or validity of any Imposition. In no event shall
the Mortgagor be entitled to delay payment of any Imposition if the delay in
payment could subject any portion of the Mortgaged Property to possible
foreclosure or in any event unless the Mortgagor deposits with Mortgagee a sum
of money or such other security as the Mortgagee deems reasonable to cover the
amount of such Imposition plus any interest or penalty that may become due as a
result of such contest.

5.       INSURANCE. The Mortgagor agrees, at the Mortgagor's sole cost and
expense, to keep the Mortgaged Property insured at all times throughout the term
of this Mortgage with policies of insurance of the types set forth below:

         (a) PROPERTY INSURANCE. Physical hazard insurance on an "all risks"
basis, including without limitation the hazards of earthquake and collapse, with
a full replacement cost endorsement (including builder's risk during any period
or periods of time that construction or remodeling is being performed on the
Mortgaged Property), in an amount equal to 100% of the full replacement cost of
all improvements (excluding only the reasonable value of footings and
foundations) and the Mortgagor's contents therein, determined to the reasonable
satisfaction of the Mortgagee, and in any event, in an amount sufficient to
prevent the Mortgagor from incurring any co-insurance liability.

         (b) SYSTEM INSURANCE. A policy or policies of insurance against loss or
damage arising from incidents relating to the air conditioning and/or heating
systems, electrical systems, other pressure vessels, high pressure piping and
machinery, if any, installed in the buildings and improvements, for an amount
reasonably satisfactory to the Mortgagee.

         (c) BUSINESS INTERRUPTION AND/OR LOSS OF RENTAL VALUE INSURANCE.
Business interruption and/or loss of rental insurance for a period of twelve
months in such amounts as are reasonably satisfactory to the Mortgagee.

         (d) FLOOD INSURANCE. If the Real Property is located in an area
designated by any governmental agency as an area of special flood hazard, such
insurance against damage caused by flooding as the Mortgagee shall reasonably
request.

         (e) AUTOMOBILE INSURANCE. Policies of comprehensive automobile
liability insurance on an occurrence basis arising out of vehicles owned,
unowned or hired by Mortgagor for bodily injury and property damage with limits
of not less than $1,000,000 in the aggregate, including $1,000,000 of primary
coverage.


   5


         (f) WORKER'S COMPENSATION. Policies of worker's compensation insurance
including employer's liability with policy limits of not less than $100,000.

         (g) LIABILITY/UMBRELLA INSURANCE. Policies of comprehensive general

bodily injury and property damage with limits of liability satisfactory to the
Mortgagee and in any event not less than $10,000,000 in the aggregate, including
$1,000,000 of primary coverage. The Mortgagor and the Mortgagee shall be named
insurers under such policies, as their interests may appear.

         (h) ADDITIONAL INSURANCE. Insurance with respect to such other
insurable risks relating to the Mortgaged Property or the Mortgagor in such
amounts and containing such terms and conditions as the Mortgagee may reasonably
require from time to time.

No such insurance shall be blanketed with insurance on other properties without
the prior written consent of the Mortgagee, which consent shall not be
unreasonably withheld. The Mortgagor shall deposit all insurance policies (or
certificates thereof acceptable to the Mortgagee) providing coverage applicable
to the Mortgaged Property, whether or not required by this Mortgage, with the
Mortgagee forthwith after the binding of such insurance, and shall deliver to
the Mortgagee new policies (or certificates thereof acceptable to the Mortgagee)
for any insurance about to expire at least thirty (30) days before such
expiration. All such insurance policies shall be first payable in case of loss
to the Mortgagee by means of a standard non-contributory mortgagee clause, shall
be written by such companies, on such terms, in such form and for such periods
and amounts as the Mortgagee shall from time to time designate or approve, shall
be primary and without right of contribution from other insurance which may be
available, shall waive any right of setoff, counterclaim, subrogation, or any
deduction in respect of any liability of the Mortgagor and the Mortgagee, shall
provide that with respect to the Mortgagee, the insurance shall not be
invalidated by any action or inaction by the Mortgagor including without
limitation any representations made by the Mortgagor in the procurement of such
insurance, and shall provide that they shall not be canceled or amended without
at least thirty (30) days' prior written notice to the Mortgagee. The Mortgagor
hereby grants the Mortgagee full power and authority as attorney irrevocable of
the Mortgagor to cancel or transfer such insurance, to collect and endorse any
checks issued in the name of the Mortgagor and to retain any premium and to
apply the same to the obligations secured hereby provided, however, that
Mortgagee shall provide Mortgagor five (5) days prior written notice before
executing any instrument as attorney in fact.

6.       MAINTENANCE AND ALTERATIONS. The Mortgagor shall maintain the Mortgaged
Property at all times in as good repair and condition as the same now is or may
hereafter be put, damage from casualty expressly not excepted. The Mortgagor
shall not take any action, or permit any condition or activity, which could
diminish the value of the Mortgaged Property or invalidate any insurance
required to be provided under this Mortgage. The Mortgagor shall not remove or
alter any of the improvements, equipment, appliances, furnishings and fixtures
constituting part of the Mortgaged Property without promptly replacing any such
item with an item of equivalent utility and value. The Mortgagor shall permit
the Mortgagee, its agents and employees reasonable opportunity to enter upon the
Mortgaged Property for the purpose of inspecting the condition of the Mortgaged
Property and determining the Mortgagor's compliance with the covenants contained
in this Mortgage.

7.       USE AND COMPLIANCE WITH LAW. The Mortgagor shall maintain the Mortgaged
Property in a first class condition and shall not change nor suffer or permit
any change in the use or character thereof without the prior written consent of
the Mortgagee. The Mortgagor shall continuously occupy all of the Real Property,
or cause the same to be occupied by the Mortgagor's lessees, licensees, or
concessionaires. The Mortgagor shall not permit any violation of any law,
by-law, ordinance, public or private restriction, regulation, order or code
affecting the Mortgaged Property or the use thereof or take any action or permit
any condition or activity which could invalidate any license or permit needed
for the use and occupancy of the Mortgaged Property. The Mortgagor shall
indemnify, defend and hold harmless the Mortgagee and each of the Mortgagee's
agents, employees, successors and contractors from and against all loss,
liability, damage and expense, and all costs associated with any defense of any
claim with respect to any of the foregoing, including attorneys' fees and
expenses, occasioned by or associated with the actual or alleged existence at
the Real Property of any substance or material, the generation, handling,
storage or disposal of which is regulated by any governmental requirement;
provided, however, that the foregoing 

   6


indemnity shall not apply if the loss, liability, damage or expense is a result
of the act or omission by the Mortgagee, its lessees, tenants, agents, employees
and independent contractors.

8.       LEASES. The Mortgagor shall observe and perform all the obligations
imposed upon the Mortgagor under any lease of the Real Property or any portion
thereof, and shall not do or permit to be done anything which would impair the
security of any such lease to the Mortgagee, nor cancel or change any terms,
conditions or covenants of any lease of the Real Property or any portion thereof
without the prior written consent of the Mortgagee, nor execute any lease
providing for payment of rent for more than one month in advance, nor receive
rent from any tenant of all or any part of the Real Property for more than one
month in advance without the prior written consent of the Mortgagee. The
Mortgagee agrees not to unreasonably withhold its consent to any change,
cancellation of the covenants of any Lease, any change in the condition of the
Premises, or concerning the execution of a Lease providing for payment of rent
for more than one month in advance. The Mortgagor agrees to hold in trust for
the benefit of the Mortgagee any such advance rent in excess of one month
received by the Mortgagor. The Mortgagor agrees to send to the Mortgagee any
notice of default given by the Mortgagor to any lessee or occupant of the Real
Property and any notice of default received by the mortgagor from any tenant or
other occupant of the Real Property, and to give prompt written notice to the
Mortgagee of any material default on the part of any tenant or other occupant of
the Real Property, whether or not the Mortgagor has given notice of such
condition to the tenant or occupant in default. No tenant or occupant under any
lease of the Real Property which is subordinate to this Mortgage shall be
entitled to terminate such tenant's or occupant's lease without giving the
Mortgagee written notice of the Mortgagor's default under such lease and, if
Mortgagor fails to cure any default within the applicable grace period, if any,
contained in said lease, giving Mortgagee an additional reasonable period of
time to cure such default. In no event shall the Mortgagee have any liability to
any tenant or occupant for any default by Mortgagor or for the return of any
security deposit given to the Mortgagor and in no event shall the Mortgagee be
subject to any setoff, defense or claim which any tenant or occupant may have
against the Mortgagor. Any tenant or occupant of the Real Property shall,
promptly after receipt of a request from the Mortgagee made at any time prior to
foreclosure of this Mortgage, execute, acknowledge and deliver to the Mortgagee
such instrument as the Mortgagee may reasonably request agreeing to attorn to
the Mortgagee, at the election of the Mortgagee, after the foreclosure of this
Mortgage.

         The Mortgagee shall have the right to subordinate this Mortgage and its
rights hereunder to any lease of the Real Property or any portion thereof which
is subordinate to this Mortgage, except that the Mortgagee shall be entitled to
expressly exclude from such subordination the Mortgagee's rights to insurance
proceeds and eminent domain awards in the event of a loss or casualty or eminent
domain taking of the Mortgaged Property or any portion thereof. If the Mortgagee
executes and records an instrument which purports to effect a partial or
complete subordination of this Mortgage to any lease which is subordinate to
this Mortgage, such lease shall not be terminated by a foreclosure of this
Mortgage, but any rights of the Mortgagee to insurance proceeds or eminent
domain awards which are expressly excluded from such subordination shall remain
superior to the rights of the tenant under such lease.

9.       CONDITIONAL ASSIGNMENT OF LEASES AND RENTS. As additional security for
the obligations secured hereby, the Mortgagor hereby assigns to the Mortgagee
all of the Mortgagor's rights under any and all leases or other arrangements for
the use or occupancy of all or any part of the Mortgaged Property, including
without limitation, the right to receive rent or other payment, provided,
however, the Mortgagor shall retain the right to receive such rents and payments
and exercise its other rights under such leases and other arrangements until the
occurrence of an Event of Default, as defined herein, under this Mortgage. After
an Event of Default, the Mortgagee shall be entitled to modify and otherwise
deal with all such leases and other arrangements with the same power and
discretion which the Mortgagee would have if it were the lessor thereof, and the
Mortgagee shall be entitled to collect all of the rents and other payments, to
collect and endorse any checks issued in the name of the Mortgagor and to apply
the same to the debt secured hereby, and after foreclosure the Mortgagee shall
not be liable to account to the Mortgagor for rents or other payments thereafter
accruing.

10.      REPORTING REQUIREMENTS. The Mortgagor shall furnish the Mortgagee, from
time to time, within a reasonable time after its demand, a true and complete
statement of the annual operating expenses and income of the Mortgaged Property
together with a rent roll, description of leasing prospects, forecasts for
income and 

   7


expenditures, and such other information concerning the Mortgaged Property as
the Mortgagee may reasonably request, and financial statements of the principal
owners and any guarantors and endorsers and if requested, shall furnish such
information on a periodic basis without additional requests. Such financial
statements shall be prepared in accordance with generally accepted principles of
accounting consistently applied, shall be in a form satisfactory to the
Mortgagee, and if requested by the Mortgagee, shall be reviewed by an
independent public accountant satisfactory to the Mortgagee.

11.      CASUALTIES AND TAKINGS. If the Mortgaged Property or any part thereof
shall be damaged or destroyed by fire or other hazard insured against, or if the
Mortgaged Property or any portion thereof or interest therein shall be taken by
eminent domain, the Mortgagor shall promptly give written notice thereof to the
Mortgagee and promptly take such action as is required to collect any applicable
insurance proceeds or any eminent domain award. No settlement on account of any
loss, damage or taking shall be made without the prior written consent of the
Mortgagee. If, in the Mortgagee's sole judgment, the Mortgagor is not proceeding
promptly to settle such claims in a manner satisfactory to the Mortgagee, or if
there has occurred an Event of Default, as defined herein, which has not been
waived in writing by the Mortgagee, the Mortgagee may settle any claims with the
insurers or taking authority and the Mortgagee is hereby irrevocably appointed
attorney-in-fact for the Mortgagor to settle such claims and to collect and
endorse any checks issued in the name of the Mortgagor. Any proceeds from
insurance or wards for such taking, as the case may be, shall be paid to the
Mortgagee.

The Mortgagee, in its discretion, may either apply any insurance proceeds or
eminent domain award against any of the obligations secured hereby, or release
all or a portion of the proceeds to the Mortgagor upon such terms and conditions
as the Mortgagee deems appropriate, and apply the balance thereof, if any, to
the obligation secured hereby.

12.      OTHER SECURITY INTERESTS AND EQUIPMENT LEASING. The Mortgagor shall not
permit, without the prior written consent of the Mortgagee, (i) the creation or
continued existence, whether by voluntary action or operation of law, of any
security interest in or other encumbrance on the Mortgaged Property other than
the lien for unpaid real estate taxes and betterment assessments prior to the
commencement of interest and penalties thereon, or (ii) the leasing of any
equipment to be used by the Mortgagor at or in connection with the operation of
the Mortgaged Property; provided, however, that in the case of a security
interest or encumbrance created by operation of law, the Mortgagor shall be
required to discharge any such encumbrance or cause the encumbrance to be bonded
over within fourteen (14) days. The Mortgagor shall notify the Mortgagee
promptly of the existence of and the terms of any security interest affecting
any portion of the Mortgaged Property and any lease of personal property to be
used by the Mortgagor at or in connection with the operation of the Real
Property, whether now existing or hereafter arising, shall make all payments
that become due to any secured party having any such security interest or any
lessor of such equipment, and at the request of the Mortgagee shall assign to
the Mortgagee all of its right, title and interest in and to any and all
agreements evidencing such security interest or lease. The Mortgagor hereby
grants the Mortgagee full power and authority as attorney-in-fact of the
Mortgagor to make, execute, acknowledge and deliver such assignments. The
Mortgagor represents that, except as previously disclosed in writing to the
Mortgagee, no such security interest or lease presently exists.

         If at any time the Mortgaged Property or any portion thereof is subject
to a security interest other than this Mortgage, or any equipment used by the
Mortgagor at or in connection with the operation of the mortgaged Property is
owned other than by the Mortgagor, the Mortgagor shall not modify, amend or fail
to comply with any term or condition of such security interest or the
obligations secured thereby, or any lease of such equipment, without the prior
written consent of the Mortgagee. Notice is given hereby to any holder of a
junior security interest in or other encumbrance on the Mortgaged Property that
the Loan Documents may be amended. The holder of any such security interest or
encumbrance, by accepting such security interest or encumbrance subject to this
Mortgage shall be deemed to have agreed to any amendment of the Loan Documents,
including without limitation any change in interest rate.

13.      UCC REPRESENTATIONS. The Mortgagor warrants that the Mortgagor's
principal place of business in Massachusetts is at 20 North Road, Bedford,
Massachusetts, and that Mortgagor has no other place of business in
Massachusetts. The Mortgagor agrees to maintain complete and accurate records
listing and describing the 

   8

Personal Property and to deliver such records to the Mortgagee form time to time
upon request of the Mortgagee. Without limiting any of the provisions of this
Mortgage, the Mortgagor hereby grants to the Mortgagee a security interest in
the Personal Property. This Mortgage shall constitute a security agreement
within the meaning of the Uniform Commercial Code as enacted in Massachusetts
with respect to the Personal Property and a security interest shall attach
thereto and shall be vested directly in the Mortgagee to secure the obligations
secured by this Mortgage. Upon the occurrence of an Event of Default, as defined
herein, and at all other times, in addition to all of its other rights hereunder
and t law and in equity, the Mortgagee shall have all of the rights of a secured
party under the Uniform Commercial Code. The Mortgagee shall have no duty of
care with respect to any part of the Mortgaged Property.

14.      TRANSFERS. The Mortgagor shall not suffer or permit a change, whether
effected by voluntary act or by operation of law, in the legal or direct or
indirect beneficial ownership of (i) the Mortgaged Property or any portion
thereof or (ii) any interest in the Mortgagor except in accordance with the
terms of the Letter of Intent and Loan Agreement. The Mortgagor shall not enter
into any lease or combination of leases or other arrangements which have the
effect of transferring to any other person or affiliated group the right to use
or occupy all or substantially all of the Real Property. The Mortgagee may,
without notice to the Mortgagor, deal with the Mortgagor's successor or
successors in interest with reference to this Mortgage and the debt secured
hereby in the same manner as with the Mortgagor without in any way releasing,
discharging or modifying the Mortgagor's liability or obligations with respect
to this Mortgage or the debt secured hereby. No transfer of any interest in any
part of the Mortgaged Property or interest therein shall operate to release,
discharge, modify, change or affect the original liability of the Mortgagor, nor
the priority of this Mortgage either in whole or in part.

15.      MORTGAGEE'S RIGHT TO CURE AND EXPENSES. The Mortgagee shall be
entitled, but not obligated, to cure any failure of the Mortgagor to perform its
obligations under this Mortgage and to commence, intervene in or otherwise
participate in any legal or equitable proceeding which in the Mortgagee's sole
judgment affects the Mortgaged Property or any rights created or secured by this
Mortgage or any obligation secured hereby. If the Mortgagee shall become
involved in any action or course of conduct with respect to the Lot 3 Note, this
Mortgage, any of the other Loan Documents, the Mortgaged Property or other
security for the debt or obligations secured hereby in order to protect its
interest therein or cure any default of the Mortgagor hereunder, the Mortgagor
shall, on demand, reimburse the Mortgagee for all reasonable charges, costs and
expenses incurred by the Mortgagee in connection therewith, including without
limitation reasonable attorneys' fees and expenses, and an additional reasonable
fee to compensate the Mortgagee for overhead and personnel salaries and wages
attributable to undertaking such actions or conduct, together with interest
thereon, from the date incurred until paid at an interest rate equal to the
rate, if any, of interest specified in the Lot 3 Note to be in effect after
there has been a default and the principal sum has been declared due and
payable, but in no event higher than the highest rate permitted by law.

16.      EVENTS OF DEFAULT. Each of the following shall constitute an Event of
Default:

         (a) failure to pay interest or principal within the applicable grace
period, if any, on the Lot 3 Note in accordance with their respective terms;

         (b) breach of the covenants, conditions or agreements in any Loan
Document or in any other mortgage, debt or obligation of or from the Mortgagor
to the Mortgagee or in any other mortgage or instrument which constitutes a lien
on all or any part of the Mortgaged Property, in each case, if it remains
uncured after the expiration of any applicable grace period;

         (c) breach of any covenant contained in the Sections herein entitled
"Insurance", "Other Security Interests and Equipment Leasing" and "Transfers";

         (d) breach of any other covenant, condition or agreement contained in
this Mortgage remaining uncured for a period in excess of fifteen (15) days;
provided that in the case of any breach which is susceptible to cure but cannot
be cured within thirty (30) days through the exercise of reasonable diligence,
so long as the Mortgagor commences such cure within thirty (30) days, such
breach remains susceptible to cure, and the Mortgagor diligently pursues such
cure, such breach shall not be deemed to create an Event of Default hereunder;

   9


         (e) failure of the Mortgagor to cause to be dismissed any proceeding
against the Mortgagor, and if applicable, any holder of a general partnership
interest in the Mortgagor, any guarantor of any of the Mortgagor's obligations
or any endorser of the Lot 3 Note (the Mortgagor and if applicable any such
general partner, guarantor or endorser shall each be an "Obligor") under any law
relating to bankruptcy, reorganization, insolvency or relief of debtors, within
thirty (30) days from the date on which it is filed or instituted, or the filing
or other institution of a proceeding by any Obligor under any such law; provided
that the Mortgagor commences dismissal efforts within said thirty (30) days and
the Mortgagor thereafter diligently pursues such dismissal, such breach shall
not be deemed to create an Event of Default until a total of ninety (90) days
from the date on which it is filed or instituted has passed.

         (f) death of any Obligor who is an individual excepting only the death
of a Trustee of any obligor, the liquidation, termination, dissolution, merger
or consolidation of any Obligor which is not an individual, the insolvency of
any Obligor or the inability of any Obligor to pay such Obligor's debts when
due;

         (g) material inaccuracy when made of any statement, representation or
warranty made by the Mortgagor to the Mortgagee in this Mortgage or in any Loan
Document; and

         (h) breach of the Statutory Condition.

         If an Event of Default shall occur, then, at the option of the
Mortgagee, without any further notice to the Mortgagor, the entire debt secured
hereby, shall be due and payable, and the Mortgagee shall have the STATUTORY
POWER OF SALE and shall be entitled to exercise any and all other rights and
remedies contained herein or in any of the Loan Documents or available at law,
including all rights and remedies available to a secured party under the Uniform
Commercial Code. The Mortgagor agrees that the requirement of the Uniform
Commercial Code with respect to personal property that a secured party give a
debtor reasonable notice of any proposed sale or disposition of the collateral
shall be met if such notice is given to the Mortgagor at least five (5) days
before the time of such sale or disposition.

17.      APPLICATION OF DEPOSITS AFTER DEFAULT. If the Mortgagor shall default
in the performance or observance of any covenant or agreement herein or
contained in the Lot 3 Note, the Mortgagee may apply toward the debt secured
hereby any deposit, payment or any sum due from the Mortgagee to the Mortgagor
without first enforcing any other rights of the Mortgagee against the Mortgagor
or against the Mortgaged Property.

18.      SEPARATE FORECLOSURE SALES AND WAIVER OF MARSHALING. The Mortgagee may,
in the exercise of the power of sale herein given, sell the Mortgaged Property
and other security in parts or parcels. Such sale may be held form time to time
by public or private sale and the power shall not be fully executed until all of
the Mortgaged Property and said other security not previously sold shall have
been sold. If surplus proceeds are realized from a foreclosure sale, the
Mortgagee shall not be liable for any interest thereon pending distribution of
such proceeds by the Mortgagee. Any separate items of property sold together for
a single price may be accounted for in one account without distinction between
the items of security or without assigning to them any proportion of such
proceeds. The Mortgagor hereby waives the application of any doctrine of
marshaling of assets.

19.      COLLECTION OF ACCOUNTS. The Mortgagee may communicate with account
debtors in order to verify the existence, amount and terms of any accounts or
contract rights and to notify account debtors of the Mortgagee's security
interest in their accounts. When requested by the Mortgagee, the Mortgagor shall
notify account debtors and indicate on all billings that payments are, when
requested by the Mortgagee, to be made directly to the Mortgagee. After an Event
of Default, the Mortgagee may require that payments on accounts be made directly
to the Mortgagee and shall have full power to collect, compromise, endorse, sell
or otherwise deal with the accounts or proceeds thereof and to perform the terms
of any contract in order to create accounts in the Mortgagee's name or in the
name of the Mortgagor with respect to the business conducted at the Real
Property.

20.      FURTHER ASSURANCES. The Mortgagor agrees to execute and cause to be
filed or recorded, and hereby appoints the Mortgagee its duly authorized
attorney-in-fact, with full power of substitution and with authority to 

   10


execute, file and record on behalf of the Mortgagor, all instruments from time
to time deemed by the Mortgagee to be necessary or appropriate to evidence
further the obligations of the Mortgagor pursuant to this Mortgage or secured by
this Mortgage, or to secure further to the Mortgagee the security intended to be
provided by this Mortgage, provided that the Mortgagee provides the Mortgagor
with not less than five (5) days' prior written notice before signing any
instrument as attorney-in-fact.


21.      NOTICES. Any notice, demand or other communication under this Mortgage
shall be in writing and shall be deemed to be delivered on the earlier of (i)
the date received, or (ii) the date of delivery, refusal, or non-delivery
indicated on the return receipt, if deposited in a United States Postal Service
depository, postage prepaid, sent registered or certified mail, return receipt
requested, by hand delivery or by reputable overnight courier, in each case
addressed to the party to receive the same at the address of such party set
forth at the beginning of this Mortgage, or at such other address as may be
designated in a notice delivered or mailed as herein provided.

22.      WAIVERS. No course of dealing by the Mortgagee and no forbearance on
the part of the Mortgagee or extension of the time for the payment of the debt
secured hereby or any other indulgence given by the Mortgagee shall operate to
release, discharge, modify, change or affect the original liability of the
Mortgagor nor affect the Mortgagee's rights later to take such action with
respect thereto, and no waiver as to any one default shall affect the
Mortgagee's rights as to any other default.

23.      ESTOPPEL CERTIFICATE. Within ten (10) days after any request by the
Mortgagee, the Mortgagor will furnish a duly acknowledged, estoppel certificate
stating the amount of the debt secured by this Mortgage, either that no offsets
or defenses exist against the indebtedness secured by this Mortgage or if such
offsets or defenses are alleged to exist the nature and extent thereof, and such
other matters concerning any Obligor or the Mortgaged Property as the Mortgagee
may reasonably request.

24.      INTERPRETATION AND BINDING EFFECT. This Mortgage shall be governed by
and construed in accordance with the laws of The Commonwealth of Massachusetts
and shall take effect as an instrument under seal. In case any provision of the
Lot 3 Note, this Mortgage, or any instrument executed by any person or
organization in connection therewith shall be found unenforceable or invalid for
any reason, such provision shall be deemed modified to the extent necessary to
be enforceable, or if such modification is not practicable, such provision shall
be deemed deleted from this Mortgage or such other instrument and the remainder
of this Mortgage or other such instrument shall remain binding on the Mortgagor
and otherwise of full force and effect. The word "Mortgagor" as used herein
means the Mortgagor named herein, whether one or several, and also means any
subsequent owner or owners of all or any part of the Mortgaged Property. All of
the covenants and agreements of the Mortgagor herein contained shall be binding
upon the Mortgagor, its heirs, executors, administrators, successors and assigns
and shall be joint and several if more than one person constitute the Mortgagor.
The word "Mortgagee" as used herein means the Mortgagee named herein and any
subsequent holder or holders of this Mortgage.

25.      LIMITATION OF LIABILITY. The Mortgagee agrees that, except as otherwise
provided in any guarantee of the Lot 3 Note or the Loan Documents, it shall
proceed only against the Mortgaged Property and any other collateral given to
secure the Lot 3 Note and that neither the Mortgagor nor any trustee or
beneficiary of Mortgagor shall be personally liable for any amounts due under
the Lot 3 Note or under the other Loan Documents for the payment of any monetary
obligation of the Mortgagor to the Mortgagee or for any deficiency which may
arise upon a foreclosure of this Mortgage or the liquidation of other collateral
given to secure the Lot 3 Note, provided that this provision shall not diminish
in any way the powers of the Mortgagee to foreclose this Mortgage and to
exercise its rights under the Loan Documents and at law in the event of default;
provided further that Mortgagor and Mortgagor's trustees and beneficiaries shall
be personally liable to the Mortgagee, to the same extent as they would have
been liable absent the foregoing: (a) for fraud or willful misrepresentations;
or (b) for the retention of any rental or other sum, not applied to expenses of
the Mortgaged Property which are actually paid to bona fide third parties, with
respect to the Mortgaged Property received at any time after the earlier of (i)
the acceleration of the Lot 3 Note, (ii) a default by the Mortgagor under any of
the Loan Documents which is not cured within the applicable grace period, or
(iii) if notice of default is required under the Loan Documents, the date such
notice is deemed to be delivered to the Mortgagor; or (c) if the Mortgagor or
any successor entity files a petition for 

   11


reorganization or liquidation or for protection from creditors under the United
States Bankruptcy Code or any similar state law.

26.      MISCELLANEOUS.

         (a) Any person or entity taking a junior mortgage or other lien on the
Mortgaged Property or interest therein, shall take said lien subject to the
rights of the Mortgagee herein to amend, modify and supplement this Mortgage,
the Lot 3 Note, and the Loan Documents and to vary the rate of interest and the
method of computing the same, and to impose additional fees and other charges
and to extend the maturity of said indebtedness, and to grant partial releases
of the lien of this Mortgage in each and every case without obtaining the
consent of the holder of such junior lien and without the lien of this Mortgage
losing its priority over the rights of any such junior lien. Nothing contained
in this section, however, shall be construed as waiving any provision contained
herein which provides, among other things, that it shall constitute an Event of
Default if the Mortgaged Property is sold, conveyed or otherwise encumbered.

         (b) Neither this Mortgage nor any other Loan Document may be modified,
amended, waived, extended, changed, discharged or terminated orally, or by any
act or failure to act on the part of the Mortgagor or the Mortgagee, but only an
agreement in writing and signed by the party against whom enforcement of any
modification, amendment, waiver, extension, change, discharge or termination is
sought and any oral modification, amendment, waiver, extension, change,
discharge or termination of any provision of this Mortgage by a representative
of any party shall be without authority and of no force and effect.

         (c) Headings in this Mortgage are for convenience and reference only
and the words and phrases contained therein shall in no way be held to explain,
modify, amplify or aid in the interpretation, construction or meaning of any of
the provisions herein.

         (d) To the extent permitted by applicable law, the Mortgagor hereby
consents to waiver of trial by jury and the Mortgagor authorizes and empowers
the Mortgagee in the name, place and stead of the Mortgagor to file this
Mortgage with the Clerk or Judge of any court of competent jurisdiction as a
statutory written consent to waiver of trial by jury.

         (e) In the event of the passage of any law or the issuance of any
judicial decision or regulation deducting from the value of the Real Property
for the purpose of taxation, any lien or charge thereon or changing in any way
the taxation of deeds of trust, mortgages or other debts secured by the Real
Property, so as to impose a tax lien or charge thereon or changing in any way
the taxation of deeds of trust, mortgages or other debts secured by the Real
Property, so as to impose a tax, either directly or indirectly, on this Mortgage
or any other Loan Document, or if the Mortgagor shall not be permitted by
applicable law to pay any Imposition or the payment of any Imposition would
violate any applicable usury law, at the option of the Mortgagee, the
indebtedness secured by this Mortgage shall become due and payable upon the
date(s) specified in a written notice given by the Mortgagee to the Mortgagor,
which date(s) shall be at least thirty (30) days after the date of such notice,
unless the Mortgagor shall be permitted in accordance with law to, and shall
actually, pay such Imposition or any other amounts becoming due in connection
with this Mortgage or from the Mortgagee as a result of any of the foregoing in
accordance with all applicable laws.

         (f) The Mortgagor shall promptly notify the Mortgagee: (i) if the
Mortgagor learns of the occurrence of a default under any of the Loan Documents;
or (ii) if the Mortgagor is aware of any other event of condition having a
material adverse effect on the Mortgagor or the Mortgaged Property. Any such
notice shall be given in writing in accordance with the provisions of Section 21
above and shall contain a detailed statement by the Mortgagor of the steps being
taken to cure such default or to remedy the event or condition having a material
adverse effect on the Mortgagor or the Mortgaged Property.

         (g) For purposes of this Mortgage, the singular shall include the
plural and vice versa, and each of the neuter, female and male genders shall
include each of the others.
