to the Underwriter in any such case to the extent that any such loss, claim,
damage or liability arises out of, or is based upon any untrue statement or
omission or alleged untrue statement or omission made in the Official Statement
with respect to the Underwriter, Issuer and the Bank and shall not be liable to
the Issuer in any such case to the extent that any such loss, claim, damage or
liability arises out of, or is based upon, any untrue statement or omission or
alleged untrue statement or omission made in the Official Statement with respect
to the Issuer, the Bank or the Underwriter.

            (b) In case any such action shall be brought against any Indemnified
Person, the Borrower shall be entitled to participate therein and, to the extent
that the Borrower wishes, to assume the defense thereof, with counsel reasonably
satisfactory to such Indemnified Person. The Indemnified Person shall promptly
notify the Borrower in writing of any claim within the scope of Section 10(a)
and after notice from the Borrower to such Indemnified Person of its election to
assume the defense thereof and the acceptance by such Indemnified Person of the
counsel chosen for such defense, the Borrower shall not be liable to such
Indemnified Person under this Section for any legal or other expenses
subsequently incurred by such Indemnified Person in connection with the defense
thereof other than reasonable costs of any investigation; provided, however that
if the named parties to any such action (including any impleaded parties)
include both the Indemnified Persons and the Borrower, the Indemnified Persons
shall have the right to select separate counsel to assume such legal defense and
to participate otherwise in the defense of such action on behalf of the
Indemnified Persons; provided, further, however, that the Borrower shall not, in
connection with any one such action or separate but substantially similar or
related actions arising out of the same general allegations or circumstances, be
liable for the fees and expenses of more than one separate firm of attorneys at
any point in time for the

                                      -10-
   11

Indemnified Persons. The Indemnified Person shall cooperate with the Borrower in
connection with the defense of any claim against which the Borrower is providing
indemnification under this Section.

            (c) The indemnity agreements contained in this Section 8 shall
remain operative and in full force and effect, regardless of any investigation
made by or on behalf of the Underwriter, or the delivery of and any payment for
any Bonds hereunder, and shall survive the termination or cancellation of this
Bond Purchase Agreement. The indemnity agreements contained in this Section
shall be in addition to and shall not limit any other indemnity agreement made
by the Borrower in connection with the transactions contemplated hereby and by
the Loan Agreement.

        9. Miscellaneous.

               Variable Rate Demand Revenue Bonds,
               Frequency & Time Systems Issue, Series 2001

Ladies and Gentlemen:

        This supplemental opinion is delivered pursuant to Section 6(a) of the
Bond Purchase Agreement dated May 30, 2001 among the Massachusetts Development
Finance Agency (the "Issuer"), Wells Fargo Brokerage Services, LLC (the
"Underwriter") and Frequency & Time Systems, Inc., a Delaware corporation (the
"Borrower"). Capitalized terms used in this opinion that are not otherwise
defined have the meanings given such terms in the Loan and Trust Agreement dated
as of May 1, 2001 (the "Loan Agreement") among the Issuer, the Borrower and
Wells Fargo Bank Minnesota, National Association, Columbia, Maryland, as
Trustee.

        1. The statements contained in the Official Statement in the sections
thereof entitled: "INTRODUCTORY STATEMENT" (excluding therefrom information
about the Bank, the Letter of Credit, the Borrower and Datum, as to which no
opinion is expressed) "SECURITY FOR THE BONDS" (excluding therefrom the material
in the subsection labeled "Letter of Credit," as to which no opinion is
expressed), "THE BONDS," "THE ISSUER" "COMMONWEALTH NOT LIABLE ON BONDS," and
"TAX MATTERS," insofar as such statements purport to summarize certain
provisions of the Bonds, and the Loan Agreement and to describe statutory
provisions relating to the exemption from Commonwealth taxes and federal


                                      A-1
   15

income taxes of interest on the Bonds, present a fair and accurate summary of
such provisions, and the statements of law and legal conclusions stated in such
sections of the Official Statement are correct.

        2. The Issuer has duly consented to the distribution of the Official
Statement.

        3. There is no authorization, approval, consent of or to the issuance by
the Issuer of the Bonds or in connection with its entering into the performance
of its obligations under the Loan Agreement or the Bond Purchase Agreement
required to be obtained by the Issuer by any federal, state, or other
governmental regulatory authority having jurisdiction in the premises that has
not been obtained, other than Blue Sky compliance and a determination of the
Massachusetts Historical Commission that the Project does not have an adverse
effect on historic resources of The Commonwealth.

        This opinion is furnished by us pursuant to your request therefor and
does not consider or extend to any agreements, representations or offering
materials concerning the Bonds not mentioned in this opinion.

        This opinion is addressed to you and may not be relied upon by any other
person. This opinion may not be published, transmitted to, filed with or
otherwise communicated to any person, firm, or institution unless we have given
our prior explicit, written consent in each instance.

        Re:    Massachusetts Development Finance Agency Variable Rate Demand
               Revenue Bonds Frequency & Time Systems Issue, Series 2001 (the
               "Bonds)


Ladies and Gentlemen:

        We have acted as counsel to Frequency & Time Systems, Inc., a Delaware
corporation (the "Borrower"), in connection with the execution and delivery by
the Company of that certain Bond Purchase Agreement, dated as of May 30, 2001
(the "Bond Purchase Agreement") among the Borrower, the Massachusetts
Development Finance Agency (the "Issuer"), and Wells Fargo Brokerage Services,
LLC (the "Underwriter") and the transactions contemplated therein. This opinion
is being delivered pursuant to Section 6(a) of the Bond Purchase Agreement.
Unless specifically defined herein or the context requires otherwise,
capitalized terms used herein shall have the meanings ascribed to them in the
Loan and Trust Agreement, dated as of May 1, 2001 (the "Loan and Trust
Agreement"), among the Issuer, the Borrower and Wells Fargo Bank Minnesota,
National Association, as trustee. (the "Trustee").

        In connection with the preparation of this opinion, we have examined the
documents listed below:

        a.     the Loan and Trust Agreement;

        b.     the Bond Purchase Agreement;

        c.     the Remarketing Agreement;

        d.     the Preliminary Official Statement, dated May 25, 2001, and the
               Official Statement, dated May 30, 2001, pertaining to the Bonds
               (collectively, the "Official Statements");

                                      B-1
   17

        e.     the Federal Tax Certificate;

        f.     the borrowing resolution of the Borrower, approving the Official
               Statements and approving and authorizing the execution and
               delivery of the Loan and Trust Agreement, the Bond Purchase
               Agreement, the Remarketing Agreement and the Federal Tax
               Certificate (the "Resolution"); and

        g.     The Certificate of Incorporation and Bylaws of the Borrower.

        The documents listed in items (a) through (c) above are hereinafter
sometimes referred to as the "Financing Documents."

        In addition, we have examined such other documents and considered such
questions of law as we have deemed necessary or appropriate. We have assumed
that there are no other documents or agreements between the Borrower, Issuer and
Underwriter which would expand or otherwise modify the respective rights and
obligations of the Borrower, Issuer and Underwriter as set forth in the Bond
Purchase Agreement and the documents required or contemplated thereby.

        We have assumed the authenticity of all documents submitted to us as
originals, the conformity with originals of all documents submitted to us as
copies, and the genuineness of all signatures (other than signatures of officers
of the Borrower). We have also assumed that, with respect to all parties to
agreements or instruments relevant hereto (other than the Borrower), such
parties had the requisite power and authority to execute, deliver and perform
such agreements or instruments, that such agreements or instruments have been
duly authorized by all requisite action, executed and delivered by such parties,
and that such agreements or instruments are the valid, binding and enforceable
obligations of such parties.

        As to questions of fact material to our opinions, we have relied upon
the representations of each party made in the Bond Purchase Agreement and the
other documents and certificates delivered in connection therewith, certificates
of officers of the Borrower, and certificates and advices of public officials
and we have made no independent investigation of such matters.

        Whenever a statement herein is qualified by "known to us," "to our
current actual knowledge," or similar phrase, it is intended to indicate that,
during the course of our representation of the Borrower, no information that
would give us current actual knowledge of the inaccuracy of such statement has
come to the attention of those attorneys in this firm who have rendered legal
services in connection with the transaction described in the introductory
paragraph hereof. However, except as otherwise expressly indicated, we have not
undertaken any independent investigation to determine the accuracy of such
statement, and any limited inquiry undertaken by us during the preparation of
this opinion letter should not be regarded as such an investigation; no
inference as to our knowledge of any matters bearing on the accuracy of any such
statement should be drawn from the fact of our representation of the Borrower.

        Based upon the foregoing, and subject to the additional assumptions,
exceptions, qualifications and limitations set forth below, we are of the
opinion that:

                                      B-2
   18

        1. The Borrower is a corporation duly incorporated, validly existing and
in good standing under the laws of the State of Delaware. The Borrower is duly
qualified to do business as a foreign corporation and is in good standing in The
Commonwealth of Massachusetts.

        2. The Borrower has the corporate power and authority to own its
properties and assets, to carry on its business as presently conducted, and to
enter into the Financing Documents and perform its obligations thereunder.

        3. The Financing Documents and the Federal Tax Certificate have been
duly authorized by all necessary corporate action on the part of the Borrower
and have been duly executed and delivered by the Borrower.

        4. The Resolution has been duly authorized by all necessary corporate
action on the part of the Borrower.

        5. The Financing Documents are legal, valid and binding obligations of
the Borrower enforceable against it in accordance with their respective terms,
except as the enforceability thereof may be subject to or limited by (a)
bankruptcy, insolvency, reorganization, arrangement, moratorium, or other
similar laws relating to or affecting the rights of creditors, and (b) general
equitable principles, regardless of whether the issue of enforceability is
considered in a proceeding in equity or at law.

        6. The execution and delivery of the Financing Documents and the
performance by the Borrower of their respective terms (a) will not breach or
result in a violation of the Borrower's Certificate of Incorporation or Bylaws,
or any judgment, order or decree of any court or arbitrator, known to us, to
which the Borrower is a party or is subject, and (b) will not, to our knowledge,
constitute a material breach of the terms, conditions or provisions of, or
constitute a default under, any material contract, undertaking, indenture or
other agreement or instrument known to us to which the Borrower is a party or by
which the Borrower's properties are bound.

        7. Except as disclosed in the Financing Documents, the exhibits and
schedules delivered in connection therewith or in the Federal Tax Certificate,
there is, to our current actual knowledge, no action, suit or proceeding pending
against the Borrower, or its properties in any court or before any governmental
authority or agency, or arbitration board or tribunal (a) which seeks to
restrain, enjoin, prevent the consummation of, or otherwise challenge the
Financing Documents or any of the transactions contemplated thereby, or (b)
which, if adversely determined, could reasonably be expected to have a material
adverse effect on the Borrower, or its business or properties (taken as a
whole).

        8. No consent, approval or authorization of, or designation, declaration
or filing with, any governmental authority is required in connection with the
valid execution, delivery and performance by the Borrower of the Financing
Documents, other than such consents, approvals, authorizations, designations,
declarations or filings as have been made or obtained on or before the date
hereof.

        In addition, we advise you, not as part of the legal opinions expressed
above, but rather on the basis of our participation in the preparation of the
Official Statements and our discussion of the contents thereof with certain
officers of the Borrower and your representatives, but without

                                      B-3
   19

independent verification, that we have no reason to believe that, as of the
respective dates of the Official Statements, the Official Statements (other than
the financial or statistical data contained therein, as to which with your
consent we are not expressing any comments) contained any untrue statement of a
material fact or omitted to state a material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading.

        We expressly do not comment upon or render any opinion with respect to
any documents referenced in the Financing Documents, except for the Federal Tax
Certificate, the Resolution and Financing Documents themselves.

        We call your attention to the fact that the Financing Documents state
that they are governed by the laws of the Commonwealth of Massachusetts and that
we are not rendering any opinion with respect to Massachusetts law. We have not
examined the question of what law would govern the interpretation or enforcement
of the Financing Documents and our opinion is based on the assumption that the
laws of the Commonwealth of Massachusetts are identical to the internal laws of
the State of California.

        We express no opinion with respect to the following:

        (i) the effect of provisions releasing or indemnifying a party against
liability for its own wrongful or negligent acts, or where indemnification is
contrary to public policy;

        (ii) the enforceability of Section 8 of the Bond Purchase Agreement or
Section 7 of the Remarketing Agreement regarding indemnification;

        (iii) the effect of California Civil Code Section 1670.5 which provides
that a court may refuse to enforce, or may limit the application of, a contract
or any clause thereof which the court finds as a matter of law to have been
unconscionable at the time it was made;

        (iv) the effect of Section 1698 of the California Civil Code which
provides in part that provisions of any instrument or agreement may only be
waived in writing will not be enforced to the extent that an oral agreement has
been executed modifying provisions of such instrument or agreement; or

        (v) any laws, statutes, ordinances, rules or regulations concerning
federal or state securities laws of "blue-sky" laws, federal or state tax laws
and regulations, or federal or state banking laws.

        We are members of the Bar of the State of California and, accordingly,
do not purport to be experts on or to be qualified to express any opinion herein
concerning, nor do we express any opinion herein concerning, any laws other than
the laws of the State of California, the General Corporation Law of the State of
Delaware and federal law.

        The foregoing opinions are being furnished to you solely for your
benefit and may not be relied upon by any other person without our prior written
consent.

                                            Very truly yours,

               Rate Demand Revenue Bonds, Frequency & Time Systems Issue, Series
               2001) (the "Bonds")

Ladies and Gentlemen:

        We have acted as counsel to Wells Fargo Bank, National Association (the
"Bank"), in connection with the issuance by the Bank of an irrevocable letter of
credit in the maximum amount of $________________ (the "Letter of Credit") in
favor of Wells Fargo Bank, National Association, pursuant to the terms of a
Second Amended and Restated Credit Agreement dated as of July 7, 2000 (as
amended from time to time, the "Credit Agreement") between the Bank and Datum
Inc., a Delaware corporation, in support of certain payments of principal and
interest due on the above-referenced Bonds.

        In so acting, we have examined executed copies of the Credit Agreement
and the Letter of Credit, and have examined and relied upon originals, or copies
certified or otherwise identified to our satisfaction, of such records,
documents, certificates or other instruments as we have deemed necessary to
enable us to render the opinion expressed below. In such examination, we have
assumed the genuineness of all signatures (other than those of the Bank), the
authenticity of all documents submitted to us as originals, the conformity with
the originals of all documents submitted to us as copies, and the accuracy of
the contents thereof.


                                      C-1
   21

        On the basis of such examination and our consideration of such questions
of law as we have deemed relevant in the circumstances, and subject to the
qualifications set forth below, we are of the opinion that:

            1. The Bank is qualified to conduct a commercial banking business in
California and, as part of such commercial banking business, has the power and
authority to execute and deliver the Credit Agreement and the Letter of Credit.

            2. The Letter of Credit is a legally valid and binding agreement of
the Bank, enforceable against it in accordance with its terms, except as
enforcement may be limited by (a) insolvency, conservatorship, receivership,
reorganization, liquidation, readjustment of debt or other similar laws
affecting or limiting the enforcement of creditors' rights generally, as such
laws may be applied in the event of the insolvency, conservatorship,
receivership, reorganization, liquidation, readjustment of debt or similar event
of the Bank, or (b) a moratorium or similar occurrence affecting the Bank. We
express no opinion as to (i) the availability of equitable remedies to persons
seeking to enforce the Letter of Credit, or (ii) whether a court in the exercise
of its equitable powers may temporarily restrain payment by the Bank of a
drawing under the Letter of Credit.

            3. The issuance of the Letter of Credit by the Bank is exempt from
the registration requirements of the Securities Act of 1933, as amended (the

                    FORM OF OPINION OF UNDERWRITER'S COUNSEL


                                 [Closing Date]



Wells Fargo Brokerage Services, LLC
Seattle, Washington

        Re:    Massachusetts Development Finance Agency Variable Rate Demand
               Revenue Bonds, Frequency & Time Systems Issue - Series 2001 -
               $2,725,000 (the "Bonds")

Ladies and Gentlemen:

        This opinion is rendered to Wells Fargo Brokerage Services, LLC, as the
Underwriter (the "Underwriter"), in connection with your offering and placement
of the Bonds, pursuant to a Bond Purchase Agreement dated as of May 1, 2001,
among Frequency & Time Systems, Inc. (the "Borrower"), the Massachusetts
Development Finance Agency (the "Issuer"), and the Underwriter (the "Bond
Purchase Agreement"). The Bonds are issued pursuant to a Loan and Trust
Agreement dated as of May 1, 2001 (the "Loan Agreement"), among the Issuer, the
Borrower and Wells Fargo Bank Minnesota, National Association, as trustee (the
"Trustee"), and are secured by a letter of credit (the "Letter of Credit")
issued by Wells Fargo Bank N.A. (the "Bank").

In our capacity as counsel for the Underwriter, we have examined originals, or
copies certified or otherwise identified to our satisfaction as being true
copies of originals, of such documents, records and other instruments as we have
deemed necessary or appropriate for purposes of this opinion including, without
limitation: (i) the Bond Purchase Agreement, (ii) the Loan Agreement, (iii)
Resolution No. _____ of the Board of Directors of the Issuer adopted May 10,
2001 (the "Resolution"), (iv) the Letter of Credit, and (v) the Official
Statement relating to the Bonds, dated May 30, 2001 (the "Official Statement").
Capitalized terms not otherwise defined herein shall have the meanings given
such terms in the Bond Purchase Agreement.

        Based on the foregoing and in reliance thereon, we are of the opinion
that the offer and sale of the Bonds is exempt from the registration
requirements of the Securities Act of 1933, as amended, and that the Loan
Agreement is exempt from qualification under the Trust Indenture Act of 1939, as
amended.

        We also have examined information made available to us in the course of
our participation in the preparation of the Official Statement as your counsel,
including legal matters


                                      E-1

and certain records, documents and proceedings, and we have attended telephone
conferences with, among others, representatives of the Underwriter, the Issuer
and its counsel, the Trustee and its counsel, the Borrower and its counsel, and
the Bank and its counsel, at which telephone conferences the contents of the
Official Statement were discussed; however, our examination of information and
participation in such conferences does not necessarily constitute such diligence
as may be specified, required or implied in sections 12(b) and 17 of the
Securities Act of 1933, as amended, Section 10(b) of the Securities Exchange Act
of 1934, as amended, and similar provisions under state securities or "blue sky"
laws or regulations promulgated pursuant thereto, to the extent such provisions
and regulations may be applicable (and no opinion is expressed as to such
applicability). Without undertaking to determine independently or assuming any
responsibility for the accuracy, completeness or fairness of the statements
contained in the Official Statement, we have no reason to believe that the
Official Statement as of this date contains any untrue statement of a material
fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein, in light of the circumstances in which
they were made, not misleading (except that we express no opinion or belief with
respect to any financial or statistical data contained in the Official Statement
or with respect to information relating to The Depository Trust Company
contained in the Official Statement).

        This opinion is furnished by us as your counsel and is solely for your
benefit.

                                            Respectfully submitted,

                                            PRESTON GATES & ELLIS, LLP


                                            By
                                                  David O. Thompson
