THESE SECURITIES HAVE NOT BEEN REGISTERED WITH THE SECURITIES AND EXCHANGE
COMMISSION OR THE SECURITIES COMMISSION OF ANY STATE IN RELIANCE UPON AN
EXEMPTION FROM REGISTRATION UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE

                             PROCOM TECHNOLOGY, INC.

                                     WARRANT

Warrant No. 1                                            Dated: October 31, 2000

        Procom Technology, Inc., a California corporation (the "COMPANY"),
hereby certifies that, for value received, Montrose Investments Ltd., or its
registered assigns (the "HOLDER"), is entitled to purchase from the Company up
to a total of 32,916 shares of common stock, $.01 par value per share (the
"COMMON STOCK"), of the Company (each such share, a "WARRANT SHARE" and all such
shares, the "WARRANT SHARES") at an exercise price equal to $32.55 per share (as
adjusted from time to time as provided in Section 9, the "EXERCISE PRICE"), at
any time and from time to time from and after the date hereof and through and
including October 31, 2005 (the "EXPIRATION DATE"), and subject to the following
terms and conditions.

        1.      Definitions. In addition to the terms defined elsewhere in this
Warrant, capitalized terms that are not otherwise defined herein have the
meanings given to such terms in the Securities Purchase Agreement, dated as of
October 31, 2000 among the Company and the Purchasers identified therein (the
"PURCHASE AGREEMENT").

        2.      Registration of Warrant. The Company shall register this
Warrant, upon records to be maintained by the Company for that purpose (the
"WARRANT REGISTER"), in the name of the record Holder hereof from time to time.
The Company may deem and treat the registered Holder of this Warrant as the
absolute owner hereof for the purpose of any exercise hereof or any distribution
to the Holder, and for all other purposes, and the Company shall not be affected
by notice to the contrary.

        3.      Registration of Transfers. The Company shall register the
transfer of any portion of this Warrant in the Warrant Register, upon surrender
of this Warrant, with the Form of Assignment attached hereto duly completed and
signed, to the Transfer Agent or to the Company at its address specified herein.
Upon any such registration or transfer, a new warrant to purchase Common Stock,
in substantially the form of this Warrant (any such new warrant, a "NEW
WARRANT"), evidencing the portion of this Warrant so transferred shall be issued
to the transferee and a New Warrant evidencing


                                       1


   2
the remaining portion of this Warrant not so transferred, if any, shall be
issued to the transferring Holder. The acceptance of the New Warrant by the
transferee thereof shall be deemed the acceptance by such transferee of all of
the rights and obligations of a holder of a Warrant.

        4.      Exercise and Duration of Warrants.

               (a) This Warrant shall be exercisable by the registered Holder at
any time and from time to time on or after the date hereof to and including the
Expiration Date. At 6:30 P.M., New York City time on the Expiration Date, the
portion of this Warrant not exercised prior thereto shall be and become void and
of no value; provided that, if the Closing Price on the Expiration Date is
greater than 102% of the Exercise Price on the Expiration Date, then this
Warrant shall be deemed to have been exercised in full (to the extent not
previously exercised) on a "cashless exercise" basis at 6:30 P.M. New York City
time on the Expiration Date; provided that so long as such exercise is honored
by the Company, the Company will have no responsibility to deliver certificates
until it receives written notice requesting such delivery.

               (b) A Holder may exercise this Warrant by delivering to the
Company (i) an Exercise Notice, in the form attached hereto, appropriately
completed and duly signed, and (ii) payment of the Exercise Price for the number
of Warrant Shares as to which this Warrant is being exercised (which may take
the form of a "cashless exercise" if so indicated in the Exercise Notice), and
the date such items are delivered to the Company (as determined in accordance
with the notice provisions hereof) is an "EXERCISE DATE." Within two Trading
Days after each Exercise Date, the Holder will deliver this Warrant (or a New
Warrant, as defined below, if applicable) to the Company, unless the Holder is
awaiting receipt of a New Warrant from the Company pursuant to another provision
hereof.

        5.      Delivery of Warrant Shares.

               (a) Upon exercise of this Warrant, the Company shall promptly
(but in no event later than three Trading Days after the Exercise Date) issue or
cause to be issued and cause to be delivered to or upon the written order of the
Holder and in such name or names as the Holder may designate, a certificate for
the Warrant Shares issuable upon such exercise, free of restrictive legends
unless a registration statement covering the resale of the Warrant Shares and
naming the Holder as a selling stockholder thereunder is not then effective and
the Warrant Shares are not freely transferable without volume restrictions
pursuant to Rule 144 under the Securities Act. The Holder, or any Person so
designated by the Holder to receive Warrant Shares, shall be deemed to have
become holder of record of such Warrant Shares as of the Exercise Date. The
Company shall, upon request of the Holder, use its best efforts to deliver
Warrant Shares hereunder electronically through the Depository Trust Corporation
or another established clearing corporation performing similar functions.

               (b) This Warrant is exercisable, either in its entirety or, from
time to time, for a portion of the number of Warrant Shares. If less than all of
the Warrant Shares which may be purchased under this Warrant are exercised at
any time, the Company shall issue or cause to be issued, at its expense, a New
Warrant evidencing the right to purchase the remaining number of Warrant Shares.

                                       2


   3
               (c) The Company's obligations to issue and deliver Warrant Shares
in accordance with the terms hereof are absolute and unconditional, irrespective
of any action or inaction by the Holder to enforce the same, any waiver or
consent with respect to any provision hereof, the recovery of any judgment
against any Person or any action to enforce the same, or any setoff,
counterclaim, recoupment, limitation or termination, or any breach or alleged
breach by the Holder or any other Person of any obligation to the Company or any
violation or alleged violation of law by the Holder or any other Person, and
irrespective of any other circumstance which might otherwise limit such
obligation of the Company to the Holder in connection with the issuance of
Warrant Shares.

        6.      Charges, Taxes and Expenses. Issuance of certificates for shares
of Common Stock upon exercise of this Warrant shall be made without charge to
the Holder for any issue or transfer tax, withholding tax, transfer agent fee or
other incidental tax or expense in respect of the issuance of such certificates,
all of which taxes and expenses shall be paid by the Company; provided, however,
that the Company shall not be required to pay any tax which may be payable in
respect of any transfer involved in the registration of any certificates for
Warrant Shares or Warrants in a name other than that of the Holder. The Holder
shall be responsible for all other tax liability that may arise as a result of
holding or transferring this Warrant or receiving Warrant Shares upon exercise
hereof.

        7.      Replacement of Warrant. If this Warrant is mutilated, lost,
stolen or destroyed, the Company shall issue or cause to be issued in exchange
and substitution for and upon cancellation hereof, or in lieu of and
substitution for this Warrant, a New Warrant, but only upon receipt of evidence
reasonably satisfactory to the Company of such loss, theft or destruction and
customary and reasonable indemnity, if requested. Applicants for a New Warrant
under such circumstances shall also comply with such other reasonable
regulations and procedures and pay such other reasonable third-party costs as
the Company may prescribe.

        8.      Reservation of Warrant Shares. The Company covenants that it
will at all times reserve and keep available out of the aggregate of its
authorized but unissued and otherwise unreserved Common Stock, solely for the
purpose of enabling it to issue Warrant Shares upon exercise of this Warrant as
herein provided, the number of Warrant Shares which are then issuable and
deliverable upon the exercise of this entire Warrant, free from preemptive
rights or any other contingent purchase rights of persons other than the Holder
(taking into account the adjustments and restrictions of Section 9). The Company
covenants that all Warrant Shares so issuable and deliverable shall, upon
issuance and the payment of the applicable Exercise Price in accordance with the
terms hereof, be duly and validly authorized, issued and fully paid and
nonassessable.

        9.      Certain Adjustments. The Exercise Price and number of Warrant
Shares issuable upon exercise of this Warrant are subject to adjustment from
time to time as set forth in this Section 9.

               (a) Stock Dividends and Splits. If the Company, at any time while
this Warrant is outstanding, (i) pays a stock dividend on its Common Stock or
otherwise makes a distribution on any class of capital stock that is payable in
shares of Common Stock, (ii) subdivides outstanding shares of Common Stock into
a larger number of shares, or (iii) combines outstanding shares of Common Stock
into a smaller number of shares, then in each such case the Exercise Price shall
be


                                       3


   4
multiplied by a fraction of which the numerator shall be the number of shares of
Common Stock outstanding immediately before such event and of which the
denominator shall be the number of shares of Common Stock outstanding
immediately after such event. Any adjustment made pursuant to clause (i) of this
paragraph shall become effective immediately after the record date for the
determination of stockholders entitled to receive such dividend or distribution,
and any adjustment pursuant to clause (ii) or (iii) of this paragraph shall
become effective immediately after the effective date of such subdivision or
combination.

               (b) Pro Rata Distributions. If the Company, at any time while
this Warrant is outstanding, distributes to all holders of Common Stock (i)
evidences of its indebtedness, (ii) any security (other than a distribution of
Common Stock covered by the preceding paragraph), (iii) rights or warrants to
subscribe for or purchase any security, or (iv) any other asset (in each case,
"DISTRIBUTED PROPERTY"), then in each such case the Exercise Price in effect
immediately prior to the record date fixed for determination of stockholders
entitled to receive such distribution shall be adjusted (effective on such
record date) to equal the product of such Exercise Price times a fraction of
which the denominator shall be such Exercise Price and of which the numerator
shall be such Exercise Price less the then fair market value of the Distributed
Property distributed in respect of one outstanding share of Common Stock, as
determined by the Company's independent certified public accountants that
regularly examine the financial statements of the Company (an "APPRAISER"). The
Appraiser will allocate its fees and expenses equitably among the parties. In
such event, the Holder, after receipt of the determination by the Appraiser,
shall have the right to select an additional appraiser (which shall be a
nationally recognized accounting firm), in which case such fair market value
shall be deemed to equal the average of the values determined by each of the
Appraiser and such appraiser. As an alternative to the foregoing adjustment to
the Exercise Price, at the request of the Holder delivered before the 90th day
after such record date, the Company will deliver to such Holder, within five
Trading Days after such request (or, if later, on the effective date of such
distribution), the Distributed Property that such Holder would have been
entitled to receive in respect of the Warrant Shares for which this Warrant
could have been exercised immediately prior to such record date.

               (c) Fundamental Transactions. If, at any time while this Warrant
is outstanding, (i) the Company effects any merger or consolidation of the
Company with or into another Person, (ii) the Company effects any sale of all or
substantially all of its assets in one or a series of related transactions,
(iii) any tender offer or exchange offer (whether by the Company or another
Person) is completed pursuant to which holders of Common Stock are permitted to
tender or exchange their shares for other securities, cash or property, or (iv)
the Company effects any reclassification of the Common Stock or any compulsory
share exchange pursuant to which the Common Stock is effectively converted into
or exchanged for other securities, cash or property (in any such case, a
"FUNDAMENTAL TRANSACTION"), then the Holder shall have the right thereafter to
receive, upon exercise of this Warrant, the same amount and kind of securities,
cash or property as it would have been entitled to receive upon the occurrence
of such Fundamental Transaction if it had been, immediately prior to such
Fundamental Transaction, the holder of the number of Warrant Shares then
issuable upon exercise in full of this Warrant (the "ALTERNATE CONSIDERATION").
The aggregate Exercise Price for this Warrant will not be affected by any such
Fundamental Transaction, but the Company shall apportion such aggregate Exercise
Price among the Alternate Consideration in a reasonable manner reflecting the
relative value of any different components of the Alternate


                                       4


   5
Consideration. If holders of Common Stock are given any choice as to the
securities, cash or property to be received in a Fundamental Transaction, then
the Holder shall be given the same choice as to the Alternate Consideration it
receives upon any exercise of this Warrant following such Fundamental
Transaction. At the Holder's request, any successor to the Company or surviving
entity in such Fundamental Transaction shall issue to the Holder a new warrant
consistent with the foregoing provisions and evidencing the Holder's right to
purchase the Alternate Consideration for the aggregate Exercise Price upon
exercise thereof. The terms of any agreement pursuant to which a Fundamental
Transaction is effected shall include terms requiring any such successor or
surviving entity to comply with the provisions of this paragraph (c) and
insuring that the Warrant (or any such replacement security) will be similarly
adjusted upon any subsequent transaction analogous to a Fundamental Transaction.
If any Fundamental Transaction constitutes or results in a Change of Control,
then at the request of the Holder delivered before the 90th day after such
Fundamental Transaction, the Company (or any such successor or surviving entity)
will purchase the Warrant from the Holder for a purchase price, payable in cash
within five Trading Days after such request (or, if later, on the effective date
of the Fundamental Transaction), equal to the Black Scholes value of the
remaining unexercised portion of this Warrant on the date of such request.

               (d) Subsequent Equity Sales.

                      (i) If, at any time while this Warrant is outstanding, the
        Company or any Subsidiary issues additional shares of Common Stock or
        rights, warrants, options or other securities or debt convertible,
        exercisable or exchangeable for shares of Common Stock or otherwise
        entitling any Person to acquire shares of Common Stock (collectively,
        "COMMON STOCK EQUIVALENTS"); (except for issuance of Common Stock or
        Common Stock Equivalents in a Strategic Transaction or the issuance of
        up to an aggregate of 100,000 shares of Common Stock after the date
        hereof (appropriately adjusted for stock splits, stock dividends,
        reverse stock splits and similar events)) at an effective price per
        share of Common Stock (the "EFFECTIVE PRICE") less than the Exercise
        Price, then the Exercise Price shall be reduced to equal the product of
        (A) the Exercise Price in effect immediately prior to such issuance of
        Common Stock or Common Stock Equivalents times (B) a fraction, the
        numerator of which is the sum of (1) the number of shares of Common
        Stock outstanding immediately prior to such issuance, plus (2) the
        number of shares of Common Stock which the aggregate Effective Price of
        the Common Stock issued (or deemed to be issued) would purchase at the
        Exercise Price, and the denominator of which is the aggregate number of
        shares of Common Stock outstanding or deemed to be outstanding
        immediately after such issuance. For purposes of the foregoing
        adjustment, in connection with any issuance of any Common Stock
        Equivalents, (x) the maximum number of shares of Common Stock
        potentially issuable at any time upon conversion, exercise or exchange
        of such Common Stock Equivalents (the "DEEMED NUMBER") shall be deemed
        to be outstanding upon issuance of such Common Stock Equivalents, (y)
        the Effective Price applicable to such Common Stock shall equal the
        minimum dollar value of consideration payable to the Company to purchase
        such Common Stock Equivalents and to convert, exercise or exchange them
        into Common Stock, divided by the Deemed Number, and (z) no further
        adjustment shall be made to the Exercise Price upon the actual issuance
        of Common Stock upon conversion, exercise or exchange of such Common
        Stock Equivalents.


                                       5


   6
                      (ii) If, at any time while this Warrant is outstanding,
        the Company or any Subsidiary issues Common Stock Equivalents with an
        Effective Price that floats or resets or otherwise varies or is subject
        to adjustment based on market prices of the Common Stock (a "FLOATING
        PRICE SECURITY"), then for purposes of applying the preceding paragraph
        in connection with any subsequent exercise, the Effective Price will be
        determined separately on each Exercise Date and will be deemed to equal
        the lowest Effective Price at which any holder of such Floating Price
        Security is entitled to acquire shares of Common Stock on such Exercise
        Date (regardless of whether any such holder actually acquires any shares
        on such date).

                      (iii) Notwithstanding the foregoing, no adjustment will be
        made under this paragraph (d) in respect of (A) the issuance of Common
        Stock upon exercise or conversion of any Common Stock Equivalents
        described in Schedule 3.1(g) to the Purchase Agreement (provided that
        such exercise or conversion occurs in accordance with the terms thereof,
        without material amendment or material modification, and that the
        applicable exercise or conversion price or ratio is described in such
        schedule), or (B) any grant of options to employees, officers or
        directors of the Company pursuant to any stock option plan duly adopted
        by the Company's board of directors or in respect of the issuance of
        Common Stock upon exercise of any such options.

               (e) Number of Warrant Shares. Simultaneously with any adjustment
to the Exercise Price pursuant to paragraphs (a), (b) or (d) of this Section,
the number of Warrant Shares that may be purchased upon exercise of this Warrant
shall be increased proportionately, so that after such adjustment the aggregate
Exercise Price payable hereunder for the increased number of Warrant Shares
shall be the same as the aggregate Exercise Price in effect immediately prior to
such adjustment.

               (f) Calculations. All calculations under this Section 9 shall be
made to the nearest cent or the nearest 1/100th of a share, as applicable. The
number of shares of Common Stock outstanding at any given time shall not include
shares owned or held by or for the account of the Company, and the disposition
of any such shares shall be considered an issue or sale of Common Stock.

               (g) Notice of Adjustments. Upon the occurrence of each adjustment
pursuant to this Section 9, the Company at its expense will promptly compute
such adjustment in accordance with the terms of this Warrant and prepare a
certificate setting forth such adjustment, including a statement of the adjusted
Exercise Price and adjusted number or type of Warrant Shares or other securities
issuable upon exercise of this Warrant (as applicable), describing the
transactions giving rise to such adjustments and showing in reasonable detail
the facts upon which such adjustment is based. Upon written request, the Company
will promptly deliver a copy of each such certificate to the Holder and to the
Company's Transfer Agent.

               (h) Notice of Corporate Events. If the Company (i) declares a
dividend or any other distribution of cash, securities or other property in
respect of its Common Stock, including without limitation any granting of rights
or warrants to subscribe for or purchase any capital stock of the Company or any
Subsidiary, (ii) authorizes or approves, enters into any agreement


                                       6


   7
contemplating or solicits stockholder approval for any Fundamental Transaction
or (iii) authorizes the voluntary dissolution, liquidation or winding up of the
affairs of the Company, then the Company shall deliver to the Holder a notice
describing the material terms and conditions of such transaction, at least 20
calendar days prior to the applicable record or effective date on which a Person
would need to hold Common Stock in order to participate in or vote with respect
to such transaction, and the Company will take all steps reasonably necessary in
order to insure that the Holder is given the practical opportunity to exercise
this Warrant prior to such time so as to participate in or vote with respect to
such transaction; provided, however, that the failure to deliver such notice or
any defect therein shall not affect the validity of the corporate action
required to be described in such notice.

        10.     Payment of Exercise Price. The Holder shall pay the Exercise
Price in one of the following manners:

               (a) Cash Exercise. The Holder may deliver immediately available
funds; or

               (b) Cashless Exercise. The Holder may satisfy its obligation to
pay the Exercise Price through a "cashless exercise," in which event the Company
shall issue to the Holder the number of Warrant Shares determined as follows:

                             X = Y [(A-B)/A]

                where:

                             X = the number of Warrant Shares to be issued to
                             the Holder.

                             Y = the number of Warrant Shares with respect to
                             which this Warrant is being exercised.

                             A = the average of the Closing Prices for the five
                             Trading Days immediately prior to (but not
                             including) the Exercise Date.

                             B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have commenced, on
the date this Warrant was originally issued pursuant to the Purchase Agreement.

        11.     Limitation on Exercise. Notwithstanding anything to the contrary
contained herein, the number of shares of Common Stock that may be acquired by
the Holder upon any exercise of this Warrant (or otherwise in respect hereof)
shall be limited to the extent necessary to insure that, following such exercise
(or other issuance), the total number of shares of Common Stock then
beneficially owned by such Holder and its Affiliates and any other Persons whose
beneficial ownership of Common Stock would be aggregated with the Holder's for
purposes of Section 13(d) of the Exchange Act, does not exceed 4.999% (the
"MAXIMUM PERCENTAGE") of the total number of issued and outstanding shares of
Common Stock (including for such purpose the shares of Common Stock issuable
upon such exercise). For such purposes, beneficial ownership shall be


                                       7


   8
determined in accordance with Section 13(d) of the Exchange Act and the rules
and regulations promulgated thereunder. Each delivery of an Exercise Notice
hereunder will constitute a representation by the Holder that it has evaluated
the limitation set forth in this paragraph and determined that issuance of the
full number of Warrant Shares requested in such Exercise Notice is permitted
under this paragraph, and the Company will have no liability for the accuracy of
such determination. The Company's obligation to issue shares of Common Stock in
excess of the limitation referred to in this Section shall be suspended (and
shall not terminate or expire notwithstanding any contrary provisions hereof)
until such time, if any, as such shares of Common Stock may be issued in
compliance with such limitation. By written notice to the Company, the Holder
may waive the provisions of this Section or increase or decrease the Maximum
Percentage to any other percentage specified in such notice, but (i) any such
waiver or increase will not be effective until the 61st day after such notice is
delivered to the Company, and (ii) any such waiver or increase or decrease will
apply only to the Holder and not to any other holder of Warrants.

        12.     Fractional Shares. The Company shall not be required to issue or
cause to be issued fractional Warrant Shares on the exercise of this Warrant. If
any fraction of a Warrant Share would, except for the provisions of this
Section, be issuable upon exercise of this Warrant, the Company shall pay an
amount in cash equal to the average of the Closing Prices of the Common Stock
for the five Trading Days immediately prior to (but not including) the Exercise
Date multiplied by such fraction; provided that, unless the Holder requests
otherwise, no payment shall be required pursuant to this sentence until the
aggregate amount payable exceeds $1,000, at which time all previously deferred
payments shall be made.

        13.     Notices. Any and all notices or other communications or
deliveries hereunder (including without limitation any Exercise Notice) shall be
in writing and shall be deemed given and effective on the earliest of (i) the
date of transmission, if such notice or communication is delivered via facsimile
at the facsimile number specified in this Section prior to 6:30 p.m. (New York
City time) on a Trading Day, (ii) the next Trading Day after the date of
transmission, if such notice or communication is delivered via facsimile at the
facsimile number specified in this Section on a day that is not a Trading Day or
later than 6:30 p.m. (New York City time) on any Trading Day, (iii) the Trading
Day following the date of mailing, if sent by nationally recognized overnight
courier service, or (iv) upon actual receipt by the party to whom such notice is
required to be given. The addresses for such communications shall be those set
forth in the Purchase Agreement (with copies as indicated therein) or such other
address or facsimile number as either party may provide to the other in
accordance with this Section.

        14.     Warrant Agent. The Company shall serve as warrant agent under
this Warrant. Upon 30 days' notice to the Holder, the Company may appoint a new
warrant agent. Any corporation into which the Company or any new warrant agent
may be merged or any corporation resulting from any consolidation to which the
Company or any new warrant agent shall be a party or any corporation to which
the Company or any new warrant agent transfers substantially all of its
corporate trust or shareholders services business shall be a successor warrant
agent under this Warrant without any further act. Any such successor warrant
agent shall promptly cause notice of its succession as warrant agent to be
mailed (by first class mail, postage prepaid) to the Holder at the Holder's last
address as shown on the Warrant Register.


                                       8


   9
        15.     Miscellaneous.

               (a) This Warrant shall be binding on and inure to the benefit of
the parties hereto and their respective successors and assigns. Subject to the
preceding sentence, nothing in this Warrant shall be construed to give to any
Person other than the Company and the Holder any legal or equitable right,
remedy or cause of action under this Warrant. This Warrant may be amended only
in writing signed by the Company and the Holder and their successors and
assigns.

               (b) The corporate laws of the State of California shall govern
all issues concerning the relative rights of the Company and its stockholders.
All other questions concerning the construction, validity, enforcement and
interpretation of this Warrant shall be governed by and construed and enforced
in accordance with the internal laws of the State of Texas, without regard to
the principles of conflicts of law thereof. The Company and the Holder hereby
irrevocably submit to the exclusive jurisdiction of the state and federal courts
sitting in Dallas, Texas, for the adjudication of any dispute hereunder or in
connection herewith or with any transaction contemplated hereby or discussed
herein, and hereby irrevocably waives, and agrees not to assert in any suit,
action or proceeding, any claim that it is not personally subject to the
