dated April 24, 1997 (the "Execution Date") and made effective as of the 21st
day of February, 1997 (the "Effective Date") by and between ROSS Technology,

YORK BRANCH, and its successors and assigns (the "Bank"). This Loan Agreement is
the First Amendment and Restatement of that certain Letter Loan Agreement made
as of the 15th day of November 1996 between ROSS and the Bank (the "Original

Substitution and full replacement of the original Loan Agreement. From and after
the date hereof, this Loan Agreement shall evidence all of the indebtedness
evidenced by the original Loan Agreement and the original Loan Agreement shall
be cancelled and of no further force. ROSS and the Bank hereby agree as follows:

            1.    ADVANCES.

                  a.    Revolving Facility A

                        (i) Upon the terms and conditions and relying upon the
representations and warranties herein set forth, the Bank agrees to make
multiple advances (each an "Advance") to ROSS in a maximum aggregate amount of
U.S. $25,000,000.00 (the "Facility A Commitment"), with effect from November 15,
1996. Within the limits of the Facility A Commitment and subject to the terms
and conditions contained herein, ROSS may borrow, repay and reborrow until the

<PAGE>   2


                        (iii) Subject to the terms and conditions of this Loan
Agreement, the aggregate principal sum which ROSS shall be entitled to borrow
and which the Bank is committed to advance hereunder is US $50,000,000.

                  b.    Note.

                        Each Advance made pursuant to the Facility
A Commitment and the Facility B Commitment shall be evidenced by a separate
promissory note (each a "Note", collectively, the "Notes"), which shall be (i)
dated the date of the Advance; (ii) in the principal amount of the Advance;
(iii) in substantially the form attached to this Loan Agreement as Exhibit A,
with the blanks appropriately filled; (iv) payable to the order of the Bank in
one (1) installment of principal in the amount of the Advance on a date no later
than June 30, 1997 (the "Maturity Date") and (v) subject to acceleration upon
the occurrence of an Event of Default (as hereinafter defined). Each Note shall
bear interest on the unpaid principal amount thereof from time to time
outstanding, payable on the date indicated in the Note (but in any event no
later than the Maturity Date), at a rate per annum (calculated based on a year
of 360 days) which shall be equal to the lesser of (i) the Bank's Quoted Rate or
(ii) the highest lawful rate of interest permitted under applicable law. For
purposes of this Loan Agreement, the Bank's Quoted Rate means, as of the
particular day on which an inquiry is made by ROSS, the rate quoted to ROSS by a
responsible officer of the Bank in New York, New York for such Advance, in
accordance with the borrowing procedure set forth in paragraph 1.c. below.

                  c.    Borrowing Procedure and Funding.

                        (1)   At any time before the Maturity Date,
ROSS may request an Advance under the Facility A Commitment or the Facility B
Commitment using the following borrowing procedure:

                              (a) ROSS shall telephone the Bank in New York and
ask a responsible officer of the Bank to provide the Bank's Quoted Rate for the
proposed Advance. ROSS shall indicate at the time of such request the amount,
the term, the borrowing date (which must be a Business Day) and whether such
proposed Advance is to be made under the Facility A Commitment or the Facility B
Commitment. To be considered, such request must be made on or before 11:00 a.m.
(New York time) on the proposed borrowing date. For the purposes of this Loan
Agreement a "Business Day" shall mean any day on which the Bank is open for
business in New York, New York.

                              (b) If ROSS accepts the Bank's Quoted Rate for
such Advance, ROSS shall complete a Note with the Bank's Quoted Rate, the amount
of the Advance and the due date of the Advance, and shall (x) send by telecopier
to the Bank a completed copy of the Note and (y) send by courier the original of
such Note for overnight delivery to the Bank in New York. The sending of the
Note by telecopier shall constitute irrevocable notice by ROSS to the Bank that
it is requesting the Advance on the basis of the terms contained in such Note.

In the event that the provisions of any Note shall conflict with the provisions
of this Loan Agreement or if any blanks in the form of note executed by ROSS
shall for any reason be left incompleted, the provisions of this Loan Agreement
(including, without limitation, Sec. 6 (c) of this Loan Agreement) shall be
controlling and resolution of any such conflict or incomplete blank shall be
made by reference to this Loan Agreement.

                        (2) Upon due receipt by the Bank of the telecopied form
of the Note on or before noon (New York time) on the proposed borrowing date,
properly completed with the Bank's Quoted Rate for the Advance, the amount of
the Advance and the due date of the Advance as provided above, the Bank shall
pay or deliver the proceeds of the Advance into ROSS' account with the Bank in
New York, New York. In the event of any discrepancy between the terms of the
telecopied form of the Note and the original Note as received by the Bank, the
terms in the telecopied form of the Note shall prevail. In the event the
applicable rate of interest is not completed on the Note, the Quoted Rate given
in connection with such Advance shall for all purposes be the rate of interest
for such Note. A certificate of such Quoted Rate, submitted by the Bank to ROSS,
will be conclusive as to the amount thereof.

                        (3) Unless an Event of Default (as hereafter defined)
has occurred and is continuing, the proceeds of the Advance in ROSS' account
with the Bank shall be available for withdrawal from the account in immediately
available funds upon receipt by the Bank of the telecopied form of the
promissory note, duly completed as aforesaid.

                  d.    Payments and Prepayments.

                        (1) ROSS shall have the right at any time and from time
to time to prepay each Note, in whole or in part, provided that each partial
prepayment shall be in an aggregate principal amount of $1,000,000.00, or
multiples thereof, and if to be applied to a Note, shall be applied to the
principal installments thereof in the inverse order of their due dates.

                        (2) All payments and prepayments made in accordance with
the provisions of this Loan Agreement or of the Notes in respect of principal or
interest on the Notes under this Loan Agreement shall be made to the Bank at its
office in New York, New York, no later than 2:00 p.m., New York time, in
immediately available funds. All payments (whether of principal, interest,
reimbursements or otherwise) under this Agreement or on the Notes shall be made
by ROSS without set-off or counterclaim and shall be made free and clear of and
without deduction for any present or future tax, levy, impost or any other
charge, if any, of any nature whatsoever now or hereafter imposed by any taxing
authority.

                        (3) If any payment shall become due on a Saturday,
Sunday, or public holiday on which the Bank is not open for business, such
payment shall be made on the next preceding day on which the Bank is open for
business.



<PAGE>   4
                        (4) ROSS hereby authorizes the Bank, if and to the
extent payment by ROSS is not made when due hereunder, to charge from time to
time against any balance in ROSS' account maintained with the Bank any amount so
due.

                        (5) ROSS shall pay a default rate on any principal and
interest which is not paid when due in an amount equal to the lesser of (A) the
Bank's Prime Rate, plus two percent (2%) per annum or (B) the highest lawful
rate permitted under applicable law. For the purposes of this provision, the
"Bank's Prime Rate" shall mean the fluctuating rate of interest from time to
time quoted by the Bank in New York as its Prime Rate.

                        (6) After any such prepayment, ROSS may request and
subject to the other terms and conditions of this Loan Agreement and provided no
Event of Default shall have occurred and be continuing, the Bank shall permit
ROSS to provide a Substitute Note for the Note upon which such prepayment was
made, which Substitute Note shall reflect the then current principal balance,
whereupon Bank shall return the Original Note to ROSS upon written request from
ROSS. ROSS hereby agrees that the execution and delivery of such Substitute Note
in the manner hereinabove provided shall not be construed, interpreted or
asserted by ROSS to constitute a novation or accord and satisfaction of the
indebtedness evidenced by the Original Note or subject to any other legal or
equitable theory or remedy pursuant to which the entire unpaid balance of
principal and interest on the Original Note might be deemed paid or satisfied
and ROSS agrees that any such legal or equitable claim or assertion shall be
void and unenforceable ab initio.

      (e)   Increased Costs.

(1) If any change in any applicable law, regulation or treaty or in the
interpretation thereof by any governmental or other authority or entity charged
with the administration thereof: (A) imposes, modifies or deems applicable any
reserve, special deposit or similar requirements against assets held by, or
deposits in or for the account of, or loans by, or any other acquisition of
funds for loans by Bank; or (B) imposes on Bank any other condition regarding
this Loan Agreement or the loans to be made pursuant hereto; or (C) changes the
basis of taxation of payments due to Bank hereunder or under any of the Notes,
this Loan Agreement or any other agreement or instrument provided by ROSS,
Fujitsu or any other person in connection herewith or as security herefor
(otherwise than by a change in taxation of the overall net income of Bank); and
if, in the sole determination of Bank, the result of any of the foregoing is to
increase the cost to Bank of making or maintaining the loans to be made pursuant
hereto or to reduce the amount
<PAGE>   5
of principal or interest received by Bank, then, upon demand made by Bank to
ROSS, ROSS will pay to Bank from time to time additional amounts specified by
Bank to compensate Bank for such increased cost or reduced amount. Bank will
promptly notify ROSS of any event which will entitle Bank to claim additional
amounts pursuant to this subsection. A certificate as to the increased cost or
expense incurred by Bank as a result of any event mentioned in this subsection,
submitted by Bank to ROSS, will be conclusive as to the amount thereof except in
the case of a manifest error.

(2) In addition to the interest payable at the Default Rate, ROSS will indemnify
Bank and hold Bank harmless against any loss or expense incurred by Bank
(including, without limitation, any loss or expense incurred by reason of the
liquidation or reemployment of deposits or other funds acquired by Bank to fund
or maintain the loans to be made pursuant hereto) as a result of the failure to
pay the outstanding principal amount of such loans at maturity. Bank will
certify to ROSS the amount of, and the basis of determination of, the loss or
expense so incurred (which certification will be conclusive in the absence of
arithmetical error).

(3) If, after the date hereof, any law, regulation or treaty or any change
therein or in the interpretation thereof by any authority or agency charged with
the administration thereof or by any court will make it, in the sole opinion of
Bank, unlawful for Bank to maintain the loans to be made pursuant hereto or to
give effect to its obligations as contemplated hereby, Bank will so notify ROSS,
and the aggregate outstanding principal amount of such loans, together with the
interest accrued thereon and any other amounts payable to Bank under the Notes,
this Loan Agreement or any other agreement or instrument provided by ROSS,
Fujitsu or any other person in connection herewith or as security herefor will
be paid or prepaid as provided in such notice.

(4) ROSS shall indemnify the Bank against and hold the Bank harmless from any
funding loss or breakage costs with respect to (a) ROSS' payment of principal of
loans on a



<PAGE>   6
day other than the last day of the applicable period for which the Quoted Rate
was given; (b) ROSS' failure to borrow the proceeds of any Advance requested by
ROSS on the date specified by ROSS; (c) ROSS' failure to make any prepayment on
the date specified by ROSS; or (d) any cessation of the Eurodollar interbank
rate relied upon by Bank in issuing the Quoted Rate to apply to any Advance or
any part thereof pursuant to Sections 1(e)(1), (2) and (3) hereof, in each case
whether voluntary or involuntary, any loss, expense, penalty, premium or
liability incurred by Bank (including but not limited to any loss or expense
incurred by reason of the liquidation or reemployment of deposits or other
funds acquired by Bank to fund or maintain a loan). This agreement shall survive
the payment of the Notes. A certificate as to any additional amounts payable
pursuant to this subsection as a result of any event mentioned in this
subsection, submitted by Bank to ROSS, will be conclusive as to the amount
thereof except in the case of a manifest error.

the Bank have been prepared on the basis of ROSS being a subsidiary of Fujitsu

with generally accepted accounting principles. At such time as any change occurs

statements shall be delivered in the manner otherwise required herein.

                  b.    Other Remedies.

                        In addition to and cumulative of any rights or remedies
expressly provided for in this Loan Agreement, if any one or more Events of
Default shall have occurred, the Bank may proceed to protect and enforce its
rights hereunder by any appropriate proceedings. The Bank may also proceed

assets in favor of ROSS or any other person.

                  c.    Cumulative Rights.

                        No remedy, right or power conferred upon the Bank is
intended to be exclusive of any other remedy, right or power given hereunder or
now or hereafter existing at law, in equity, or otherwise, and all such
remedies, rights and powers shall be cumulative.

            6.    OTHER PROVISIONS.

                  a.    No Waiver, Modifications, Conflicts.

                        No failure or delay on the part of the Bank in
exercising any power or right hereunder shall operate as a waiver thereof, nor
shall any single or partial exercise of any such right or power, or any
abandonment or discontinuance of steps to enforce such a right or power,
preclude any other or further exercise thereof or the exercise of any other
right or


<PAGE>   12
power. No course of dealing between ROSS and the Bank shall operate as a waiver
of any right of the Bank. No modification or waiver of any provision of this
Loan Agreement, any Note or the Facility A Guaranty or the Facility B Guaranty
nor consent to any departure by ROSS therefrom shall in any event be effective
unless the same shall be in writing, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No
notice to or demand on ROSS in any case shall entitle ROSS to any other or
further notice or demand in similar or other circumstances. Notwithstanding
anything to the contrary contained herein or in a Note, in the event that the
provisions of any Note shall conflict with the provisions of this Loan Agreement
or if any blanks in the form of note executed by ROSS shall for any reason be
left incompleted, the provisions of this Loan Agreement (including, without
limitation, 6(c) of this Loan Agreement) shall be controlling and resolution of
any such conflict or incomplete blank shall be made by reference to this Loan
Agreement.

                  b.    Notices.

                        All notices and other communications provided for herein
shall be in writing (including telex, facsimile, or cable communication) and
shall be mailed, telecopied, telexed, cabled or delivered addressed to a party
at the address set forth on the first page of this Loan Agreement, or to such
other address as shall be designated by such party in a written notice to the
other party. All such notices and communications shall, when mailed, telecopied,
telexed, transmitted, or cabled, become effective when deposited in the mail,
confirmed by telex answerback, transmitted to the telecopier, or delivered to
the cable company, except that notices and communications to the Bank shall not
be effective until actually received by the Bank.

                  c.    Reimbursement of Expenses.

                        Any provision hereof to the contrary notwithstanding,
ROSS agrees to reimburse the Bank for its reasonable out-of-pocket expenses,
including the reasonable fees and expenses of counsel to the Bank, in connection
with transactions contemplated by this Loan Agreement, including its preparation
and its enforcement. ROSS agrees to pay any and all stamp and other taxes
related to this Loan Agreement and the transactions contemplated hereby, and to
save the Bank harmless from any and all liabilities with respect to or resulting
from any delay or omission to pay any such taxes which may be payable or
determined to be payable in connection with the execution and delivery of this
Loan Agreement or any of the Notes. The obligations of ROSS under this paragraph
shall survive the termination of this Loan Agreement and the payment of the
Notes.

                  d.    Set-Off.

                        If one or more Events of Default shall occur and be
continuing, the Bank shall have the right, in addition to all other rights and
remedies available to it, to set off against the unpaid balance of any Note any
debt owing to ROSS by the Bank, including, without limitation, any funds in any
deposit account, whether general or special in nature, maintained



<PAGE>   13

by ROSS with the Bank, and nothing in this Loan Agreement shall be deemed a
waiver or prohibition of the Bank's right of banker's lien or set-off.

                  e.    Indemnification.

                        ROSS agrees to indemnify, defend, and save harmless the
Bank and its officers, directors, employees, agents, and attorneys, and each of
them (the "Indemnified Parties"), from and against all claims, actions, suits,
and other legal proceedings, damages, costs, interest, charges, taxes (other
than income taxes of the Bank), counsel fees, and other expenses and penalties
which any of the Indemnified Parties may sustain or incur by reason of or
arising out of (i) the making of the Advances hereunder, the execution and
delivery of this Loan Agreement and the Notes and the consummation of the
transactions contemplated thereby and the exercise of any of the Bank's rights
under this Loan Agreement and any Note; provided, that no Indemnified Party
shall be entitled to the benefits of this paragraph to the extent its own gross
negligence or willful misconduct contributed to its loss; and provided, further,
that it is the intention of ROSS to indemnify the Indemnified Parties against
the consequences of their own negligence. This Loan Agreement is intended to
protect and indemnify the Indemnified Parties against all risks hereby assumed
by ROSS. The obligations of ROSS under this paragraph shall be notwithstanding
any other provision of this Loan Agreement to the contrary and shall survive the
repayment of the Notes and any termination of this Loan Agreement.

                  f.    Interest.

                        All agreements between ROSS and the Bank, whether now
existing or hereafter arising and whether written or oral, are hereby expressly
limited so that in no contingency or event whatsoever, whether by reason of
demand being made on any Note or otherwise, shall the amount paid, or agreed to
be paid, to the Bank for the use, forbearance, or detention of the money to be
loaned under this Loan Agreement or otherwise or for the payment or performance
of any covenant or obligation contained herein or in the Notes exceed the
highest lawful rate permitted under applicable law. If, as a result of any
circumstances whatsoever, fulfillment of any provision hereof or of any of such
documents, at the time performance of such provision shall be due, shall involve
transcending the limit of validity prescribed by applicable usury law, then,
ipso facto, the obligation to be fulfilled shall be reduced to the limit of such
validity, and if, from any such circumstance, the Bank shall ever receive
interest or anything which might be deemed interest under applicable law which
would exceed the highest lawful rate of interest permitted under applicable law,
such amount which would be excessive interest shall be applied to the reduction
of the principal amount owing on account of the Notes or the amounts owing on
other obligations of ROSS to the Bank under any Loan Document and not to the
payment of interest, or if such excessive interest exceeds the unpaid principal
balance of the Notes and the amounts owing on other obligations of ROSS to the
Bank under any Loan Document, as the case may be, such excess shall be refunded
to ROSS. All sums paid or agreed to be paid to the Bank for the use,
forbearance, or detention of the indebtedness of ROSS to the Bank shall, to the
extent permitted by applicable law, be amortized, prorated, allocated, and
<PAGE>   14

spread throughout the full term of such indebtedness until payment in full of
the principal thereof (including the period of any renewal or extension thereof)
so that the interest on account of such indebtedness shall not exceed the
highest lawful rate of interest permitted under applicable law. The terms and
provisions of this paragraph shall control and supersede every other provision
of all agreements between ROSS and the Bank.

                  g.    Governing Law; Jurisdiction; Process Agent.

      THIS LOAN AGREEMENT AND THE NOTES SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE UNITED STATES OF
AMERICA. ROSS HEREBY EXPRESSLY SUBMITS TO THE COMPETENT JURISDICTION OF THE
COURTS OF THE STATE OF NEW YORK OR OF THE UNITED STATES DISTRICT COURTS LOCATED
IN NEW YORK, NEW YORK, AS THE BANK MAY ELECT. ROSS IRREVOCABLY CONSENTS TO THE
SERVICE OF ANY AND ALL PROCESS IN ANY SUCH ACTION OR PROCEEDING BY THE MAILING
OF COPIES OF SUCH PROCESS TO ROSS AT ITS ADDRESS SET FORTH IN THIS AGREEMENT.
ROSS AGREES THAT A FINAL JUDGMENT IN ANY SUCH ACTION OR PROCEEDING SHALL BE
CONCLUSIVE AND MAY BE ENFORCED IN OTHER JURISDICTIONS BY SUIT ON THE JUDGMENT OR
IN ANY OTHER MANNER PROVIDED BY LAW. ROSS FURTHER WAIVES ANY OBJECTION TO VENUE
IN SUCH STATE AND ANY OBJECTION TO ANY ACTION OR PROCEEDING IN SUCH STATE ON THE
BASIS OF FORUM NON CONVENIENS. NOTHING HEREIN SHALL AFFECT THE RIGHT OF THE BANK
TO SERVE LEGAL PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR AFFECT THE RIGHT
TO THE BANK TO BRING ANY ACTION OR PROCEEDING AGAINST ROSS OR ITS PROPERTY IN
THE COURTS OF ANY OTHER JURISDICTIONS.

                  h.    Counterparts.

                        This Agreement may be executed in several counterparts,
and by the parties hereto on separate counterparts, and each counterpart, when
so executed and delivered, shall constitute an original instrument, and all such
separate counterparts shall constitute but one and the same instrument.

                  i.    Final Agreement.

                        THIS WRITTEN LOAN AGREEMENT REPRESENTS THE FINAL
AGREEMENT BETWEEN THE PARTIES AND MAY NOT BE CONTRADICTED BY EVIDENCE OF PRIOR,
CONTEMPORANEOUS, OR SUBSEQUENT ORAL AGREEMENTS OF THE PARTIES. THERE ARE NO
UNWRITTEN ORAL AGREEMENTS BETWEEN THE PARTIES.
