                          REVOLVING LINE OF CREDIT NOTE


$30,000,000.00                                              San Jose, California
                                                                  April 28, 1999

        FOR VALUE RECEIVED, the undersigned SMART MODULAR TECHNOLOGIES, INC.
("Borrower") promises to pay to the order of WELLS FARGO BANK, NATIONAL
ASSOCIATION ("Bank") at its office at Santa Clara Valley Regional Commercial
Banking Office, 121 Park Center Plaza, San Jose, California, or at such other
place as the holder hereof may designate, in lawful money of the United States
of America and in immediately available funds, the principal sum of Thirty
Million Dollars ($30,000,000.00), or so much thereof as may be advanced and be
outstanding, with interest thereon, to be computed on each advance from the date
of its disbursement as set forth herein.

DEFINITIONS:

        As used herein, the following terms shall have the meanings set forth
after each, and any other term defined in this Note shall have the meaning set
forth at the place defined:

        (a)     "Business Day" means any day except a Saturday, Sunday or any
other day on which commercial banks in California are authorized or required by
law to close.

        (b)     "Fixed Rate Term" means a period commencing on a Business Day
and continuing for one (1), two (2) or three (3) months, as designated by
Borrower, during which all or a portion of the outstanding principal balance of
this Note bears interest determined in relation to LIBOR; provided however, that
no Fixed Rate Term may be selected for a principal amount less than one Million
Dollars ($1,000,000.00); and provided further, that no Fixed Rate Term shall
extend beyond the scheduled maturity date hereof. If any Fixed Rate Term would
end on a day which is not a Business Day, then such Fixed Rate Term shall be
extended to the next succeeding Business Day.

        (c)     "LIBOR" means, for each Fixed Rate Term, the rate per annum
(rounded upward, if necessary, to the nearest whole 1/16 of 1%) and determined
pursuant to the following formula:

        LIBOR =                Base LIBOR
                      -------------------------------
                      100% - LIBOR Reserve Percentage

        (i)     "Base LIBOR" means the average of the rates per annum (rounded
upward, if necessary, to the nearest 1/16 of 1%) at which U.S. dollar deposits
are offered to Agent in the London interbank Eurocurrency market on the second
Business Day prior to the commencement of a Fixed Rate Term at or about 11:00
A.M. (London time), for delivery on the first day of such Fixed Rate



<PAGE>   2

Term, for a term comparable to the number of days in such Fixed Rate Term and in
an amount approximately equal to the principal amount to which such Fixed Rate
Term shall apply.

        (ii)    "LIBOR Reserve Percentage" means the reserve percentage
prescribed by the Board of Governors of the Federal Reserve System (or any
successor) for "Eurocurrency Liabilities" (as defined in Regulation D of the
Federal Reserve Board, as amended), adjusted by Bank for expected changes in
such reserve percentage during the applicable Fixed Rate Term.

        (d)     "Prime Rate" means at any time the rate of interest most
recently announced within Bank at its principal office as its Prime Rate, with
the understanding that the Prime Rate is one of Bank's base rates and serves as
the basis upon which effective rates of interest are calculated for those loans
making reference thereto, and is evidenced by the recording thereof after its
announcement in such internal publication or publications as Bank may designate.

INTEREST:

        (a)     Interest. The outstanding principal balance of this Note shall
bear interest (computed on the basis of a 360-day year, actual days elapsed)
either (i) at a fluctuating rate per annum one percent (1.0%) below the Prime
Rate in effect from time to time, or (ii) at a fixed rate per annum determined
by Bank to be one percent (1.0%) above LIBOR in effect on the first day of the
applicable Fixed Rate Term. When interest is determined in relation to the Prime
Rate, each change in the rate of interest hereunder shall become effective on
the date each Prime Rate change is announced within Bank. With respect to each
LIBOR selection hereunder, Bank is hereby authorized to note the date, principal
amount, interest rate and Fixed Rate Term applicable thereto and any payments
made thereon on Bank's books and records (either manually or by electronic
entry) and/or on any schedule attached to this Note, which notations shall be
prima facie evidence of the accuracy of the information noted.

        (b)     Selection of Interest Rate Options. At any time any portion of
this Note bears interest determined in relation to LIBOR, it may be continued by
Borrower at the end of the Fixed Rate Term applicable thereto so that all or a
portion thereof bears interest determined in relation to the Prime Rate or to
LIBOR for a new Fixed Rate Term designated by Borrower. At any time any portion
of this Note bears interest determined in relation to the Prime Rate, Borrower
may convert all or a portion thereof so that it bears interest determined in
relation to LIBOR for a Fixed Rate Term designated by Borrower. At such time as
Borrower requests an advance hereunder or wishes to select a LIBOR option for
all or a portion of the outstanding principal balance hereof, and at the end of
each Fixed Rate Term, Borrower shall give Bank notice specifying: (i) the
interest rate option




                                      -2-
<PAGE>   3

selected by Borrower; (ii) the principal amount subject thereto; and (iii) for
each LIBOR selection, the length of the applicable Fixed Rate Term. Any such
notice may be given by telephone so long as, with respect to each LIBOR
selection, (A) Bank receives written confirmation from Borrower not later than
three (3) Business Days after such telephone notice is given (provided that
Bank's failure to receive such notice shall not invalidate an advance which has
been made), and (B) such notice is given to Bank prior to 10:00 a.m., California
time, on the first day of the Fixed Rate Term. For each LIBOR option requested
hereunder, Bank will quote the applicable fixed rate to Borrower at
approximately 10:00 a.m., California time, on the first day of the Fixed Rate
Term. If Borrower does not immediately accept the rate quoted by Bank, any
subsequent acceptance by Borrower shall be subject to a redetermination by Bank
of the applicable fixed rate; provided however, that if Borrower fails to accept
any such rate by 11:00 a.m., California time, on the Business Day such quotation
is given, then the quoted rate shall expire and Bank shall have no obligation to
permit a LIBOR option to be selected on such day. If no specific designation of
interest is made at the time any advance is requested hereunder or at the end of
any Fixed Rate Term, Borrower shall be deemed to have made a Prime Rate interest
selection for such advance or the principal amount to which such Fixed Rate Term
applied.

        (c)     Additional LIBOR Provisions.

        (i)     If Bank at any time shall determine that for any reason adequate
and reasonable means do not exist for ascertaining LIBOR, then Bank shall
promptly give notice thereof to Borrower. If such notice is given and until such
notice has been withdrawn by Bank, then (A) no new LIBOR option may be selected
by Borrower, and (B) any portion of the outstanding principal balance hereof
which bears interest determined in relation to LIBOR, subsequent to the end of
the Fixed Rate Term applicable thereto, shall bear interest determined in
relation to the Prime Rate.

        (ii)    If any change after the date hereof in law, treaty, rule,
regulation or determination of a court or governmental authority or any change
therein or in the interpretation or application thereof (each, a "Change in
Law") shall make it unlawful for Bank (A) to make LIBOR options available
hereunder, or (B) to maintain interest rates based on LIBOR, then in the former
event, any obligation of Bank to make available such unlawful LIBOR options
shall immediately be cancelled, and in the latter event, any such unlawful
LIBOR-based interest rates then outstanding shall be converted, at Bank's
option, so that interest on the portion of the outstanding principal balance
subject thereto is determined in relation to the Prime Rate; provided however,
that if any such Change in Law shall permit any LIBOR-based interest rates to
remain in effect until the expiration of the Fixed Rate Term applicable
thereto, then such




                                      -3-
<PAGE>   4
permitted LIBOR-based interest rates shall continue in effect until the
expiration of such Fixed Rate Term. Upon the occurrence of any of the foregoing
events, Borrower shall pay to Bank immediately upon demand such amounts as may
be necessary to compensate Bank for any fines, fees, charges, penalties or other
costs incurred or payable by Bank as a result thereof and which are attributable
to any LIBOR options made available to Borrower hereunder, and any reasonable
allocation made by Bank among its operations shall be conclusive and binding
upon Borrower.

        (iii)   If any Change in Law or compliance by Bank with any request or
directive (whether or not having the force of law) from any central bank or
other governmental authority shall:

        (A)     subject Bank to any tax, duty or other charge with respect to
                any LIBOR options, or change the basis of taxation of payments
                to Bank of principal, interest, fees or any other amount payable
                hereunder (except for changes in the rate of tax on the overall
                net income of Bank); or

        (B)     impose, modify or hold applicable any reserve, special deposit,
                compulsory loan or similar requirement against assets held by,
                deposits or other liabilities in or for the account of, advances
                or loans by, or any other acquisition of funds by any office of
                Bank; or

        (C)     impose on Bank any other condition;

and the result of any of the foregoing is to increase the cost to Bank of
making, renewing or maintaining any LIBOR options hereunder and/or to reduce any
amount receivable by Bank in connection therewith, then in any such case,
Borrower shall pay to Bank immediately upon demand such amounts as may be
necessary to compensate Bank for any additional costs incurred by Bank and/or
reductions in amounts received by Bank which are attributable to such LIBOR
options. In determining which costs incurred by Bank and/or reductions in
amounts received by Bank are attributable to any LIBOR options made available to
Borrower hereunder, any reasonable allocation made by Bank among its operations
and demonstrated to Borrower shall be conclusive and binding upon Borrower.

        (d)     Payment of Interest. Interest accrued on this Note shall be
payable on the first day of each month, commencing June 1, 1999.

        (e)     Default Interest. From and after the maturity date of this Note,
or such earlier date as all principal owing hereunder becomes due and payable by
acceleration or otherwise, the outstanding principal balance of this Note shall
bear interest until paid in full at an increased rate per annum (computed on the
basis of a 360-day year, actual days elapsed) equal to four




                                      -4-

percent (4%) above the rate of interest from time to time applicable to this
Note.

BORROWING AND REPAYMENT:

        (a)     Borrowing and Repayment. Borrower may from time to time during
the term of this Note borrow, partially or wholly repay its outstanding
borrowings, and reborrow, subject to all of the limitations, terms and
conditions of this Note and of the Credit Agreement, defined below; provided
however, that the total outstanding borrowings under this Note shall not at any
time exceed the principal amount stated above. The unpaid principal balance of
this obligation at any time shall be the total amounts advanced hereunder by the
holder hereof less the amount of principal payments made hereon by or for
Borrower, which balance may be endorsed hereon from time to time by the holder.
The outstanding principal balance of this Note shall be due and payable in full
on May 1, 2000.

        (b)     Advances. Advances hereunder, to the total amount of the
principal sum stated above, shall be made by the holder at the oral or written
request of (i) Ajah Shah or Lata Krishnan or David Mullin or Jack Pacheco, any
one acting alone, who are authorized to request advances and direct the
disposition of any advances until written notice of the revocation of such
authority is received by the holder at the office designated above, or (ii) any
person, with respect to advances deposited to the credit of any account of any
Borrower with the holder, which advances, when so deposited, shall be
conclusively presumed to have been made to or for the benefit of each Borrower
regardless of the fact that persons other than those authorized to request
advances may have authority to draw against such account. The holder shall have
no obligation to determine whether any person requesting an advance is or has
been authorized by any Borrower.

        (c)     Application of Payments. Each payment made on this Note shall be
credited first, to any interest then due and second, to the outstanding
principal balance hereof. All payments credited to principal shall be applied
first, to the outstanding principal balance of this Note which bears interest
determined in relation to the Prime Rate, if any, and second, to the outstanding
principal balance of this Note which bears interest determined in relation to
LIBOR, with such payments applied to the oldest Fixed Rate Term first.

PREPAYMENT:

        (a)     Prime Rate. Borrower may prepay principal on any portion of this
Note which bears interest determined in relation to the Prime Rate at any time,
in any amount and without penalty.



                                      -5-
<PAGE>   6

        (b)     LIBOR. Borrower may prepay principal on any portion of this Note
which bears interest determined in relation to LIBOR at any time and in the
minimum amount of Ten Thousand Dollars ($10,000.00); provided however, that if
the outstanding principal balance of such portion of this Note is less than said
amount, the minimum prepayment amount shall be the entire outstanding principal
balance thereof. In consideration of Bank providing this prepayment option to
Borrower, or if any such portion of this Note shall become due and payable at
any time prior to the last day of the Fixed Rate Term applicable thereto by
acceleration or otherwise, Borrower shall pay to Bank immediately upon demand a
fee which is the sum of the discounted monthly differences for each month from
the month of prepayment through the month in which such Fixed Rate Term matures,
calculated as follows for each such month:

        (i)     Determine the amount of interest which would have accrued each
                month on the amount prepaid at the interest rate applicable to
                such amount had it remained outstanding until the last day of
                the Fixed Rate Term applicable thereto.

        (ii)    Subtract from the amount determined in (i) above the amount of
                interest which would have accrued for the same month on the
                amount prepaid for the remaining term of such Fixed Rate Term at
                LIBOR in effect on the date of prepayment for new loans made for
                such term and in a principal amount equal to the amount prepaid.

        (iii)   If the result obtained in (ii) for any month is greater than
                zero, discount that difference by LIBOR used in (ii) above.

Each Borrower acknowledges that prepayment of such amount may result in Bank
incurring additional costs, expenses and/or liabilities, and that it is
difficult to ascertain the full extent of such costs, expenses and/or
liabilities. Each Borrower, therefore, agrees to pay the above-described
prepayment fee and agrees that said amount represents a reasonable estimate of
the prepayment costs, expenses and/or liabilities of Bank. If Borrower fails to
pay any prepayment fee when due, the amount of such prepayment fee shall
thereafter bear interest until paid at a rate per annum two percent (2.0%) above
the Prime Rate in effect from time to time (computed on the basis of a 360-day
year, actual days elapsed). Each change in the rate of interest on any such past
due prepayment fee shall become effective on the date each Prime Rate change is
announced within Bank.

EVENTS OF DEFAULT:

        This Note is made pursuant to and is subject to the terms and conditions
of that certain Credit Agreement between Borrower and Bank dated as of May 1,
1998, as amended from time to time




                                      -6-
<PAGE>   7

(the "Credit Agreement"). Any default in the payment or performance of any
obligation under this Note, or any defined event of default under the Credit
Agreement, shall constitute an "Event of Default" under this Note.

MISCELLANEOUS:

        (a)     Remedies. Upon the occurrence of any Event of Default, the
holder of this Note, at the holder's option, may declare all sums of principal
and interest outstanding hereunder to be immediately due and payable without
presentment, demand, notice of nonperformance, notice of protest, protest or
notice of dishonor, all of which are expressly waived by each Borrower, and the
obligation, if any, of the holder to extend any further credit hereunder shall
immediately cease and terminate. Borrower shall pay to the holder immediately
upon demand the full amount of all payments, advances, charges, costs and
expenses, including reasonable attorneys' fees (to include outside counsel fees
and all allocated costs of the holder's in-house counsel), expended or incurred
by the holder in connection with the enforcement of the holder's rights and/or
the collection of any amounts which become due to the holder under this Note,
and the prosecution or defense of any action in any way related to this Note,
including without limitation, any action for declaratory relief, whether
incurred at the trial or appellate level, in an arbitration proceeding or
otherwise, and including any of the foregoing incurred in connection with any
bankruptcy proceeding (including without limitation, any adversary proceeding,
contested matter or motion brought by Bank or any other person) relating to any
Borrower or any other person or entity.

        (b)     Obligations Joint and Several. Should more than one person or
entity sign this Note as a Borrower, the obligations of each such Borrower shall
be joint and several.

        (c)     Governing Law. This Note shall be governed by and construed in
accordance with the laws of the State of California.


        IN WITNESS WHEREOF, the undersigned has executed this Note as of the
date first written above.
